Este tesis fue publicado como artículo científico en la Revista Archivos de Medicina (DOI: http://doi.org/10.3823/1269) / Introducción. La nutrición en el Recién Nacido Pretérmino (RNPT) de Muy Bajo Peso al Nacer (MBPN) juega un rol importante en su recuperación y evolución general. Así, un soporte nutricional insuficiente puede resultar en un menor crecimiento y mayor incidencia de patologías, lo que perjudicaría la morbimortalidad de estos neonatos. Objetivo. Determinar la asociación entre el soporte nutricional y la mortalidad a los 28 días en RNPT de MBPN hospitalizados durante el año 2011 en la Unidad de Cuidados Intensivos Neonatales de un hospital público de referencia en Lima, Perú. Pacientes y método. Se realizó una cohorte retrospectiva con 60 historias clínicas de los RNPT de MBPN, nacidos y hospitalizados en la Unidad de Cuidados Intensivos Neonatales de un hospital de referencia durante el año 2011 en Lima, Perú. Se evaluó la evolución del soporte nutricional y del peso, y se asoció con la mortalidad. Resultados. 7 (11,7%) RNPT de MBPN fallecieron durante el estudio. Aquellos RNPT de MBPN que recibieron menos de 30 kcal/kg al tercer día, tuvieron 5 veces más riesgo de morir (IC 95% 1,1 – 23,5) con una diferencia estadísticamente significativa (p=0,036). Conclusiones. Recibir menores aportes nutricionales al tercer día está asociado con un mayor riesgo de mortalidad en estos neonatos. / Introduction. The nutrition in Very Low Birth Weight (VLBW) infants plays an important role in their recovery and overall development. Thus, an inadequate nutritional support can result in lower growth and higher incidence of diseases, which may affect the morbidity and mortality of these infants. Objective. Determine the association between the mortality at 28 days and the nutritional support given to VLBW infants hospitalized during 2011 in the Neonatal Intensive Care Unit of a public referral hospital in Lima, Peru. Patients and method. This retrospective cohort included 60 medical records from VLBW Infants, born and hospitalized during 2011 in the Neonatal Intensive Care Unit of a public referral hospital in Lima, Peru. The evolution of the nutritional support and weight was evaluated, and was associated with the mortality. Results. 7 (11.7%) VLBW infants died during the study. Those VLBW infants who received less than 30 kcal/kg on the third day, were 5 times more likely to die (CI 95% 1,1 – 23,5), with a statistically significant difference (p=0,036). Conclusions. Receive lower nutritional intake on the third day is associated with an increased risk of mortality in these infants. / Tesis

<p>Uvod: Infertilitet se defini&scaron;e kao bezuspe&scaron;na koncepcija nakon jedne godine seksualnih odnosa bez upotrebe kontracepcije u fertilnoj fazi menstrualnog ciklusa. Metode asistirane reprodukcije predstavljaju efektivan način lečenja infertiliteta. Ispitivanje i identifikacija kratkoročnih i dugoročnih efekata arteficijalnih reproduktivnih tehnologija je veoma izazovan zadatak. Prvenstveni razlog tome je velika heterogenost u načinu sakupljanja, obrade, klasifikacije i tumačenja, sada već, obilja informacija koje su prikupljene u različitim istraživanjima. Individualni pristup lečenju neplodnosti, brz napredak i stalne promene u metodologiji arteficijalnih reproduktivnih tehnologija, uz ranije navedene pote&scaron;koće u vezi sa prikupljanjem i analizom podataka, značajno otežavaju precizno sagledavanje svih mogućih rizika i posledica arteficijanog začeća. Uprkos brojnim istraživanjima, naučnim publikacijama i akumuliranim dokazima, ostale su mnoge dileme u vezi odgovora na pitanja - da li su arteficijalno začete trudnoće u većoj meri praćene rizicima za neadekvatan razvoj ploda, lo&scaron;ijim perinatalnim ishodom i kakve su dugoročne posledice po decu, kao i da li su ovi rizici podjednako zastupljeni u jednoplodnim i vi&scaron;eplodnim trudnoćama.<br />Cilj rada: Ciljevi rada su bili da se utvrdi struktura morbiditeta kod prevremeno rođene dece začete vantelesnom oplodnjom (iz jednoplodnih i vi&scaron;eplodnih trudnoća) u prve dve godine života, te da se identifikuju perinatalni faktori koji su povezani sa pojavom akutnih i hroničnih komplikacija i oboljenja kod prevremeno rođene dece začete vantelesnom oplodnjom. Takođe, cilj rada je bio da se utvrde karakteristike psihomotornog razvoja kod prevremeno rođene dece začete vantelesnom oplodnjom na kraju dvanestog, osamnaestog i dvadesetčetvrtog meseca života, kao i da se identifikuju specifični faktori rizika za nepovoljan telesni, neurolo&scaron;ki i psiholo&scaron;ki ishod lečenja kod prevremeno rođene dece začete vantelesnom oplodnjom.<br />Materijal i metode: U studiju su uključena prevremeno rođena deca koja su bila hospitalizovana u Službi za neonatologiju i intenzivnu i poluintenzivnu negu i terapiju, i koja su nakon toga, tokom prve dve godine života redovno praćena u neonatolo&scaron;koj ambulanti Instituta za zdravstvenu za&scaron;titu dece i omladine Vojvodine u Novom Sadu. Retrospektivnim delom studije su obuhvaćena deca koja su lečena u Službi i praćena u neonatolo&scaron;koj ambulanti, a koja su rođena počev od 01. 01. 2011. do 31.12.2012. godine i praćena do navr&scaron;ena puna 24 meseca života. Podaci o pacijentima koji su uključeni u retrospektivni deo istraživanja prikupljani su pregledom medicinske dokumentacije. U prospektivni deo studije su uključena deca koja su lečena u Službi i koja su praćena u neonatolo&scaron;koj ambulanti, a koja su rođena između 01.01. 2013.godine i 31.12.2014. godine i potom praćena do navr&scaron;enih 24 meseca života. Iz navedene kohorte, formirane se dve grupe: Ispitivana grupa (Grupa 1) je obuhavatila svu prevremeno rođenu decu začetu vantelesnom oplodnjom koja su bila hospitalizovana i praćena na Institutu u navedenom periodu. Kontrolna grupa (Grupa 2) obuhvatila je prevremeno rođenu decu začetu prirodnim putem. Deca iz kontrolne grupe izabrana su iz kohorte tako da njihov broj bude jednak broju dece iz ispitivane grupe. Ispitanici iz ove grupe su ujednačeni (&#39;&#39;mečovani&#39;&#39;) sa decom iz ispitivane grupe prema gestacijskoj starosti i datumu rođenja. Gestacijska starost ispitanika iz kontrolne grupe se ne razlikuje za vi&scaron;e od &plusmn; 4 dana u odnosu na decu iz ispitivane grupe. Datum rođenja ispitanika koji su uključeni u kontrolnu grupu se ne razlikuje za vi&scaron;e od &plusmn; 3 meseca u odnosu na decu iz ispitivane grupe.<br />U momentu uključivanja u studiju uzimani su sledeći anamezni podaci:<br />Podaci u vezi sa majkom, trudnoći i porođaju: starost majke u momentu koncepcije, broj prethodnih poku&scaron;aja asistirane koncepcije, stručna sprema, mesto stanovanja, hronične bolesti dijagnostikovane pre trudnoće, akutne i hronične bolesti dijagnostikovane tokom trudoće (hipertenzija, pre-eklampsija, eklampsija, o&scaron;tećenje jetre), prevremena ruptura plodovih ovojaka, primena lekova tokom trudnoće, jednoplodna ili vi&scaron;eplodna trudnoća. Podaci o poremećajima posteljice i ovojaka: ablacija, placenta previja, horioamnionitis. Podaci u vezi sa detetom: intrauterina infekcija, intrauterina restrikcija rasta, način porođaja, Apgar skor. Antropometrijski parametri (telesna masa, telesna dužina, obim glave) na rođenju i tokom perioda ambulantnog praćenja deteta. Dužina inicijalne hospitalizacije deteta. Dužina invazivne i/ili neinvazivne respiratorne potpore i oksigenoterapije. Dijagnoze na otpustu iz bolnice: prisustvo te&scaron;kih posledica prematuriteta, &scaron;to podrazumeva: intrakranijalnu hemoragiju 3. i 4. stepena (definisanu u međunarodnoj klasifikaciji bolesti &ndash; deseta revizija (MKB10) pod &scaron;ifrom P52.2), cističnu periventrikularnu leukomalaciju, retinopatiju prematuriteta, bronhopulmonalnu displaziju, nekrotizirajući enterokolitis, sepsu i/ili meningitis (mikrobiolo&scaron;ki ili klinički dijagnostikovanu). Prisustvo urođenih anomalija ili genetskih sindroma i bolesti (definisanih u MKB10 pod &scaron;iframa Q00 do Q99), kao i prisustvo urođenih bolesti metabolizma (definisanih u MKB10 pod &scaron;iframa E00 do E90).<br />U retrospektivnom delu studije, pregledani su specijalistički izve&scaron;taji iz neonatolo&scaron;ke ambulante pri posetama deteta u uzrastu deteta od 12, 18 i 24 meseca, i beleženi su sledeći podaci: sve prethodno postavljene dijagnoze koje su navedene na specijalističkim izve&scaron;tajima iz neonatolo&scaron;ke ambulante, antropometrijski prametri u momentu pregleda (telesna dužina, telesna masa i obim glave), neurolo&scaron;ki nalaz (tonus, trofika, kožni i tetivni refleksi, prisustvo lateralizacije u neurolo&scaron;kom nalazu), nalaz oftalmologa (uredan nalaz/patalo&scaron;ki nalaz), procena fine i grube motorike, govora, kognitivne funkcije i socijalnog kontakta i zbirna procena psihomotornog razvoja. U prospektivnom delu studije, pri kontrolnim pregledima u neonatolo&scaron;koj ambulanti, u uzrastu deteta od 12, 18 i 24 meseca, određivano je i beleženo sledeće: ranije postavljene dijagnoze koje su navedene u medicinskoj dokumentaciji, antropometrijski prametri u momentu pregleda (telesna dužina, telesna masa i obim glave), neurolo&scaron;ki nalaz (tonus, trofika, kožni i tetivni refleksi, prisustvo lateralizacije u neurolo&scaron;kom nalazu), nalaz oftalmologa (uredan nalaz/patalo&scaron;ki nalaz), procena fine i grube motorike, govora, kognitivne funkcije i socijalnog kontakta i zbirna procena psihomotornog razvoja.<br />Rezultati: Prosečna vednost TM ispitanika iz Grupe 1, u uzrastu od 12 meseci, bila je statistički značajno manja u odnosu na ispitanike iz Grupe 2 (Studentov t test). Prosečne vednosti TD ispitanika iz obe grupe, u uzrastu od 12 meseci, nisu se statistički značajno razlikovale (Studentov t test). Prosečne vednosti OGL ispitanika iz obe grupe, u uzrastu od 12 meseci, nisu se statistički značajno razlikovale (Studentov t test). Udeo ispitanika sa patolo&scaron;kim oftalmolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Fi&scaron;erov test tačne verovatnoće). Udeo ispitanika sa patolo&scaron;kim neurolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Hi kvadrat test). Prosečne vrednosti globalnog koeficijenta razvoja (RQ), kao i prosečne vrednosti skora za pojedine elemente za procenu razvoja (motorika, koordinacija, govor i dru&scaron;tvenost) po Brunet -L&eacute;zine skali, nisu se statistički značajno razlikovale između grupa (Studentov t test). U Grupi 1 bilo je 92 (59,740%) deteta čiji je nekorigovani RQ bio ispod 90, dok je u Grupi 2 bilo 61 (39,610%) dete čiji je nekorigovani RQ bio ispod 90. Ova razlika u broju dece sa RQ koji je ispod proseka za kalendarski uzrast je statistički značajna (Hi kvadrat test, p=0,0004). Relativni rizik za ispodprosečno postignuće na testu za procenu psihomotornog razvoja (RQ&lt;90), za decu iz Grupe 1 bio je vi&scaron;i, u odnosu na decu iz Grupe 2 (RR = 1,495; 95% CI 1,181 &ndash; 1,892). U Grupi 1, bilo je 87 (56,494%) dece koja su postigla ispodprosečne korigovane vrednosti skora na testu za procenu psihomotornog razvoja (korigovani RQ&lt;90). U Grupi 2 bilo je 69 (44,805%) dece koja su postigla ispodprosečne korigovane vrednosti skora na testu za procenu psihomotornog razvoja (korigovani RQ&lt;90). Ova razlika je statistički značajna (Hi kvadrat test, p =0,040). Relativni rizik za ispodprosečno postignuće na testu za procenu psihomotornog razvoja (korigovani RQ&lt;90), za decu iz Grupe 1 bio je vi&scaron;i, u odnosu na decu iz Grupe 2 (RR = 1,261; 95%CI 1,008 &ndash; 1,577). U kategoriji dece, koja su i pored korekcije u odnosu na GS imala ispodprosečno postignuće na testu za procenu psihomotornog razvoja, u Grupi 1 čak 81/87 (93,310%) dece je imalo vrednost korigovanog RQ &ge; 85, a u Grupi 2 ovu vrednost korigovanog RQ imalo je 60/69 (86,956%) dece.<br />Prosečne vednosti TM ispitanika iz obe grupe, u uzrastu od 18 meseci, nisu se statistički značajno razlikovale (Studentov t test). Prosečne vednosti TD ispitanika iz obe grupe, u uzrastu od 18 meseci, nisu se statistički načajno razlikovale (Studentov t test). Prosečne vednosti OGL ispitanika iz obe grupe, u uzrastu od 18 meseci, nisu se statistički značajno razlikovale (Studentov t test). Udeo ispitanika sa patolo&scaron;kim oftalmolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Hi kvadrat test). Udeo ispitanika sa patolo&scaron;kim neurolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Hi kvadrat test). Prosečne vrednosti RQ, kao i prosečne vrednosti skora za pojedine elemente za procenu razvoja (motorika, koordinacija, govor i dru&scaron;tvenost) po Brunet -L&eacute;zine skali su se statistički značajno razlikovale između grupa u uzrastu od 18 meseci (Studentov t test). U Grupi 1 bilo je 57 (37,013%) dece čiji je nekorigovani RQ bio ispod 90, dok je u Grupi 2 bilo 31 (20,130%) dete čiji je nekorigovani RQ bio ispod 90. Udeo dece sa RQ koji je ispod proseka za kalendarski uzrast je statistički značajno različit između grupa (Hi kvadrat test, p = 0,010). Relativni rizik za ispodprosečno postignuće na testu za procenu psihomotornog razvoja (nekorigovani RQ&lt;90), za decu iz Grupe 1 bio je vi&scaron;i, u odnosu na decu iz Grupe 2 (RR = 1,288; 95%CI 1,181 &ndash; 2,730). Statistički značajna razlika postojala je i kada je upoređen broj dece sa vrednostima korigovanog RQ ispod 90 u Grupi 1 i Grupi 2 (36 naspram 19 po redosledu navođenja; Hi kvardat test, p = 0,011). Relativni rizik za ispodprosečno postignuće na testu za procenu psihomotornog razvoja (korigovani RQ&lt;90), za decu iz Grupe 1 bio je vi&scaron;i, u odnosu na decu iz Grupe 2 (RR = 1,895; 95%CI 1,139 &ndash; 3,152).<br />Prosečne vednosti TM ispitanika iz obe grupe, u uzrastu od 24 meseca, nisu se statistički značajno razlikovale (Studentov t test). Prosečne vednosti TD ispitanika iz obe grupe, u uzrastu od 24 meseca, nisu se statistički značajno razlikovale (Studentov t test). Prosečne vednosti OGL ispitanika iz obe grupe, u uzrastu od 24 meseca, nisu se statistički značajno razlikovale (Studentov t test). Udeo ispitanika sa patolo&scaron;kim oftalmolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Hi kvadrat test). Udeo ispitanika sa patolo&scaron;kim neurolo&scaron;kim nalazom nije se statistički značajno razlikovao između Grupe 1 i Grupe 2 (Hi kvadrat test). Prosečne vrednosti RQ, kao i prosečne vrednosti skora za pojedine elemente za procenu razvoja (motorika, koordinacija, govor i dru&scaron;tvenost) po Brunet -L&eacute;zine skali, nisu se statistički značajno razlikovale između grupa, u uzrastu od 24 meseca (Studentov t test). U Grupi 1 bilo je 21 dete (13,636%) čiji je nekorigovani RQ bio ispod 90, dok je u Grupi 2 bilo 17 (11,049%) dece čiji je nekorigovani RQ bio ispod 90. Razlika u broju dece sa RQ koji je ispod proseka za kalendarski uzrast nije statistički značajna (Hi kvadrat test, p= 0,488). Statistički značajna razlika nije postojala ni kada je upoređen broj dece sa vrednostima korigovanog RQ ispod 90 u Grupi 1 i Grupi 2 (12 naspram 9 po redosledu navođenja; Hi kvardat test, p = 0,497).<br />Logističkom regresionom analizom pokazano je da su ve&scaron;tačko začeće, vi&scaron;eplodnost trudnoće i IUGR nezavisni faktori rizika za manju TM u kalendarskom uzrastu od 12 meseci. Logističkom regresionom analizom dobijena je statistički značajna korelacija između vrednosti RQ u uzrastu od 18 meseci i sledećih nezavisnih varijabli: arteficijalno začeta trudnoća i vi&scaron;eplodna trudnoća. Isptanici iz Grupe 1 i Grupe 2 nisu se statistički značajno razlikovali ni po jednom od posmatranih pokazatelja telesnog i psihomotornog razvoja u uzrastu od 24 meseca.<br />Struktura morbiditeta kod dece, tokom dvogodi&scaron;njeg perioda praćenja, nije se značajno razlikovala između grupa. Jedina razlika između grupa, konstatovana je u uzrastu od 12 i 18 meseci, bila je u učestalosti akutnih respiratornih infekcija, čija je pojava, pak, bila direktno povezana sa vi&scaron;eplodnim trudnoćama, odnosno brojem siblinga u domaćinstvu.<br />Zaključak: Prosečna starost majki dece koja su začeta IVF-om je veća od prosečne starosti majki dece koja su spontano začeta. Struktura morbiditeta majki dece koja su začeta IVF-om i majki dece koja su začeta spontanom koncepcijom je ista, ali je stopa morbiditeta veća kod majki dece koja su začeta IVF-om. Vi&scaron;eplodne trudnoće su veoma zastupljene kod začeća IVF-om. Trudnoće začete IVF-om se dominantno i skoro ekskluzivno okončavaju carskim rezom. Prevremena ruptura ovojaka ploda je česta komplikacija trudnoća koje su začete IVF-om. Stopa morbiditeta prevremeno rođene dece začete vantelesnom oplodnjom nije veća u odnosu na prevremeno rođenu decu začetu prirodnim putem. U strukturi morbiditeta kod dece koja su začeta vantelesnom opodnjom, zastupljena su ista oboljenja i komplikacije kao kod prevremeno rođene dece začete prirodnim putem. Incidencija pojedinih oboljenja je ista, sa izuzetkom bronhopulmonalne displazije koja se javlja če&scaron;če kod dece začete vantelesnom oplodnjom i retinopatije prematuriteta koja se javlja če&scaron;če kod dece začete prirodnim putem. Porođajna telesna masa, intrauterina restrikcija rasta, starost majke, stručna sprema majke, prethodna hronična oboljenja majke, bolesti majke dijagnostikovane tokom trudnoće, jednoplodna i vi&scaron;eplodna trudnoća, način porođaja i PROM su potencijalni faktori rizika za lo&scaron;iji postnatalni ishod kod dece iz arteficijalno začetih trudnoća. U uzrastu od 12 meseci, prevremeno rođena deca začeta tehnikama in vitro fetrilizacije, sem po dostignutoj telesnoj masi, ne razlikuju se značajno po drugim telesnim karakteristikama, od prevremeno rođene dece koja su začeta prirodnim putem. Faktori rizika za manju telesnu masu kod prevremeno rođene dece, u uzrastu od 12 meseci su: arteficijalno začeće, vi&scaron;eplodne trudnoće i intrauterina restrikcija rasta. U uzrastu od 12 meseci, prevremeno rođena deca začeta in vitro fertilizacijom, imaju blago lo&scaron;ije (ali ne i značajno niže) postignuće na testovima za procenu psihomotornog razvoja, odnosno imaju vi&scaron;i rizik da postignu ispodprosečne vrednosti skora na testu za procenu psihomotornog razvoja. U uzrastu od 18 meseci, nema razlike u pokazateljima telesnog razvoja između prevremeno rođene dece koja su arteficijalno začeta i dece koja su rođena iz spontano začetih trudnoća. U uzrastu od 18 meseci, prevremeno rođena deca iz arteficijalno začetih trudnoća imaju niže postignuće na testovima za procenu psihomotornog razvoja u odnosu na prevremeno rođenu decu iz spontano začetih trudnoća. Faktori rizika koji su povezani sa lo&scaron;ijim postignućem na testu za procenu psihomotornog razvoja kod prevremeno rođene dece su arteficijalno začeće trudnoće i vi&scaron;eplodnost trudnoće. U uzrastu od 24 meseca nema razlike u telesnim parametrima između prevremeno rođene dece koja su arteficijalno začeta i prevremeno rođene dece koja su začeta prirodnim putem. U uzrastu od 24 meseca nema razlike u postignuću na testu za procenu psihomotornog razvoja kod prevremeno rođene dece su arteficijalno začeće trudnoće i vi&scaron;eplodnost trudnoće. U uzrastu od 24 meseca, prevremeno rođena deca, i iz arteficijalno, i iz spontano začetih trudnoća, na testu za procenu psihomotornog razvoja postižu rezultate koji su u skladu sa njihovim kalendarskim uzrastom.</p> / <p>Introduction: Infertility is defined as an unsuccessful conception after one year of sexual intercourse without the use of contraception in the fertilizing phase of the menstrual cycle. Assisted reproduction methods represent an effective way of treating infertility. Examination and identification of short-term and long-term effects of artificial reproductive technologies is a very challenging task. The primary reason for this is the great heterogeneity in the way of collecting, processing, classifying and interpreting, now, the abundance of information that has been gathered in various studies. Individual approach to the treatment of infertility, rapid progress and constant changes in the methodology of the artificial reproductive technologies, in addition to the aforementioned difficulties associated with the collection and analysis of data, significantly hamper accurate assessment of all possible risks and consequences artificial conception. Despite numerous studies, scientific publications and the accumulated evidence, many doubts about the question whether artificially conceived pregnancies are accompanied by the higher risks or inadequate fetal development, poor perinatal and long-term outcomes still remained.<br />The Aim: The objectives of this work were to determine the structure of morbidity in prematurely born children conceived by artificial reproductive technologies (from single and multiple pregnancies) in the first two years of life, and to identify perinatal factors that are associated with the occurrence of acute and chronic complications and diseases in prematurely born children from this pregnancies. In addition, the aim of the study was to determine the characteristics of psychomotor development in prematurely born children conceived by artificial reproductive technologies at the end of the twelfth, eighteenth and twenty-fourth month of life, as well as to identify specific risk factors for the unfavorable physical, neurological and psychological outcome of those children.<br />Materials and Methods: The study included premature born newborns who were hospitalized in the Department for neonatology and intensive and semi-intensive care unit, and are thereafter, during the first two years of life. The retrospective part of the study included children who were hospitalized at the Institute, and who were born from January 1st 2011. to December 31st 2012. and were followed up to 2 years of life. Data on patients included in the retrospective part of the survey were collected through a review of medical records. The prospective part of the study included children who were treated and followed up at the Institute, and who were born between January 1st 2013 and December 31st 2014. and then followed up to 2 years of life. From this cohort two groups were formed: The tested group (Group 1) included all preterm infants who were conceived by ART. The control group (Group 2) included naturally conceived prematurely born children. The children in the control group were selected from the cohort so that their number was equal to the number of children in the study group. The gestational age of the examinees from the control group does not differ for more than &plusmn; 4 days from the children from the study group. The date of birth of subjects included in the control group does not differ for more than &plusmn; 3 months from the children in the study group.<br />At the moment of inclusion in the study, the following individual data were taken:<br />Maternal data, pregnancy and childbirth: the age of the mother at the moment of conception, the number of previous attempts at assisted conception, professional care, place of residence, chronic diseases diagnosed before pregnancy, acute and chronic diseases diagnosed during pregnancy (hypertension, pre-eclampsia, eclampsia, liver damage), premature rupture of the fetuses, the use of medication during pregnancy, single or multiple pregnancy. Data on placental disorders and abnormalities: ablation, placenta overdose, horioamnionitis. Child-related data: intrauterine infection, intrauterine growth restriction, delivery method, Apgar score. Anthropometric parameters (body weight, body length, head circumference) at birth and during the period of outpatient monitoring of the child. Length of initial hospitalization of the child. Length of invasive and / or non-invasive respiratory support and oxygen therapy. Diagnosis on discharge from the hospital: the presence of severe consequences of prematurity, which implies intracranial hemorrhage of 3rd and 4th degree (defined in International Classification of Disease - Tenth Revision (MKB10) under code P52.2), cystic periventricular leukomalacia, retinopathy of prematurity, bronchopulmonary dysplasia , necrotizing enterocolitis, sepsis and / or meningitis (microbiologically or clinically diagnosed). Presence of congenital anomalies or genetic syndromes and diseases (defined in MKB10 under codes Q00 to Q99), as well as the presence of congenital metabolic diseases (defined in MKB10 under codes E00 to E90).<br />In the retrospective part of the study, specialist reports from a neonatological clinic were examined for child visits at the age of 12, 18 and 24 months, and the following data were ecorded: all pre-diagnosis reported on specialist reports from a neonatological clinic, anthropometric arms at the moment examination (body length, body weight and head circumference), neurological findings (tone, trophic, skin and tendon reflexes, presence of lateralization in neurological findings), ophthalmologist findings (neat / patial findings), assessment of fine and coarse motoring, speech, cognitive functions and social contact and a collective assessment of psychomotor development. In the prospective part of the study, during control examinations in a neonatological clinic, at the age of 12, 18 and 24 months, the following were determined and recorded: previously set out in the current medical documentation, anthropometric parameters at the moment of examination (body length, body weight and the volume of the head), neurological findings (tone, trophic, skin and tendon reflexes, presence of lateralization in neurological findings), ophthalmologist findings, assessment of fine and grose motor functions, speech, cognitive functions, social contact and psychomotor development.<br />Results: The average BW of subjects in Group 1 at the age of 12 months, was statistically significantly lower in relation to respondents from Group 2 (Student&#39;s T test). The average length of subjects from both groups at the age of 12 months did not statistically differ (Student&#39;s T test). The average head circumference between children from both groups, at the age of 12 months, did not statistically differ (Student&#39;s T test). The proportion of subjects with pathological ophthalmological findings did not statistically significantly differ between Group 1 and Group 2 (Fischer&#39;s exact probability test). The proportion of subjects with pathological neurological findings did not statistically significantly differ between Group 1 and Group 2 (Hi square test). The average values of the global development coefficient (RQ), as well as the average score values for individual elements of development evaluation test - Brunet-L&eacute;zine scale (motor function, coordination, speech and sociability) did not differ significantly between groups (Student t test). In Group 1 there were 92 (59.740%) of children whose uncorrected RQ was under 90, while in Group 2 there were 61 (39.610%) children whose uncorrected RQ was below 90. This difference in the number of children with RQ below the average for calendar age is statistically significant (Hi square test, p = 0.0004). The relative risk of under-achievement in the psychomotor evaluation test (RQ &lt;90) for children from Group 1 was higher than in children from Group 2 (RR = 1.495; 95% CI 1.181 - 1.922). In Group 1, there were 87 (56.494%) children who achieved sub-optimal corrected score values for the assessment of psychomotor development (corrected RQ &lt;90). In Group 2, there were 69 (44.805%) children who achieved sub-optimal corrected score values for the assessment of psychomotor development (corrected RQ &lt;90). This difference is statistically significant (Hi square test, p = 0.040). The relative risk for the suboptimal achievement in the psychomotor evaluation test (corrected RQ &lt;90) for children from Group 1 was higher than in Group 2 (RR = 1.261; 95% CI 1.008 - 1.577). In Group 1, as many as 81/87 (93.310%) of children had a corrected RQ value of &ge; 85, while in Group 2 this value of the corrected RQ there were 60/69 (86.956%) children.<br />At the age of 18 months, the average BW of subjects from both groups did not differ significantly (Student&#39;s T test). The average length of subjects from both groups, at the age of 18 months, did not statistically differ (Student&#39;s T test). The average head circumference of children from both groups, at the age of 18 months, did not statistically differ (Student&#39;s T test). The proportion of subjects with pathological ophthalmological findings did not statistically significantly differ between Group 1 and Group 2 (Hi square test). The proportion of subjects with pathological neurological findings did not statistically differ between Group 1 and Group 2 (Hi square test). The average RQ values, as well as the average scores for individual elements of psychomotor development (motor function, coordination, speech and sociability) according to the Brunet-L&eacute;zine scale, have been statistically significantly different between groups, at the age of 18 months (Student&#39;s T test). In Group 1 there were 57 (37.013%) children whose uncorrected RQ was below 90, while in Group 2 there were 31 (20,130%) children whose uncorrected RQ was below 90. The share of children with RQ below the average value for the calendar age is statistically significantly different between groups (Hi square test, p = 0.010). The relative risk for the suboptimal achievement in the Psychomotor Development Assessment (uncorrected RQ &lt;90) for Group 1 children was higher than in Group 2 (RR = 1.288; 95% CI 1.181 - 2.730). A statistically significant difference between Group 1 and Group 2 existed when the number of children with corrected RQ below 90 was compared (36 naspram 19 respectively, Hi quadrate test, p = 0.011). The relative risk for the suboptimal achievement on the Psychomotor Evaluation Test (corrected RQ &lt;90) for the children from Group 1 was higher when compared to children in Group 2 (RR = 1.895; 95% CI 1.139 &ndash; 3.152).<br />At the age of 24 months the average BW, body length and head circumference of subjects in both groups were not significantly different (Student&#39;s T test). The proportion of subjects with pathological ophthalmological findings did not statistically significantly differ between Group 1 and Group 2 (Hi square test). The proportion of subjects with pathological neurological findings did not statistically significantly differ between Group 1 and Group 2 (Hi square test). The average RQ values, as well as the average score values for individual elements for development evaluation (motor function, coordination, speech and sociability) according Brunet-L&eacute;zine scale, did not significantly differ between groups at the age of 24 months (Student&#39;s T test). In Group 1, there were 21 children (13.636%) whose uncorrected RQ was under 90, while in Group 2 there were 17 (11.049%) of children whose uncorrected RQ was below 90. The difference in the number of children with RQ below the average for the calendar age was not statistically significant (Hi square test, p = 0.488). A statistically significant difference did not exist even when the number of children with values of the corrected RQ below 90 in Group 1 and Group 2 (12 naspram 9 respectively, Hi quadrate test, p = 0.497) was compared.<br />Logistic regression analysis has shown that artificial conception, multiple pregnancy and IUGR are independent risk factors for lesser BW in a calendar age of 12 months. By logistic regression analysis, a statistically significant correlation between RQ values at 18 months of age and the following independent variables was obtained: artificially started pregnancy and multiple pregnancy. Group 1 and Group 2 patients did not significantly differ by any of the indicators of physical and psychomotor development at the age of 24 months.<br />The structure of morbidity in children, during the two-year follow-up period, did not differ significantly between groups. The only difference between the groups was found in the rates of acute respiratory infections at the age of 12 and 18 months (rate of infections was higher in Group 1), whose occurrence, however, was directly related to multiple pregnancies, or the number of sibling in the household.<br />Conclusion: The average age of mothers of children conceived by the IVF is higher than the average age of mothers of children who were conceived spontaneously. The structure of the morbidity of mothers of children who were artificially conceived and mothers of children born after spontaneous conception is the same, but the morbidity rate is higher in the mothers of children who were conceived by IVF. Pregnancies concieved by IVF almost exclusively ended by cesarean section. Premature rupture of the membranes is a common complication of IVF pregnancies. The rate of morbidity of prematurely born children conceived by ART is not higher than that of prematurely born children conceived naturally. The structure of morbidity in children from ART pregnancies was the same as in naturally conceived prematurely born children. The incidence of specific illnesses is the same, with the exception of bronchopulmonary dysplasia that occurs more frequently in children born from ART pregnancies, and retinopathy of prematurity that occurs more frequently in spontaneously conceived children. Maternal birth weight, intrauterine growth restriction, mother&#39;s age, maternal care, previous mother&#39;s chronic illness, mother&#39;s disease diagnosed during pregnancy, single and multiple pregnancies and PROM are potential risk factors for worse postnatal outcome in children from artificially initiated pregnancies. Risk factors for lower body weight in premature babies, at the age of 12 months, are: artificial conception, multiple pregnancy and intrauterine growth restriction. At the age of 12 months, prematurely born children from IVF pregnancies, have slightly worse (but not significantly lower) psychomotor achievements. At the age of 18 months, there is no difference in the indicators of physical development between prematurely born children who are artificially conceived and children born from spontaneous pregnancies. At the age of 18 months, prematurely born children from ART pregnancies have lower achievement on tests for assessing psychomotor development compared to prematurely born children from spontaneously initiated pregnancies. Risk factors associated with a poor performance on the psychomotor development assessment tests, in preterm infants, are an artificial conception of pregnancy and a multi fertile pregnancy. At the age of 24 months, there is no difference in the physical parameters between prematurely born children from ART and naturally conceived pregnancies. At the age of 24 months, there is no difference in the achievement on the test for the assessment of psychomotor development between children from ART and spontaneous pregnancies. At the age of 24 months, on the psychomotor development assessment, prematurely born children achieve the results consistent with their calendar age.</p>

INTRODUÇÃO: Os relatos do desenvolvimento motor de recém-nascidos prétermo (RNPT) extremo são razoavelmente bem documentados, mas pouco se sabe sobre o desenvolvimento de RNPT Tardios (RNPT T). OBJETIVOS: Analisar o desenvolvimento motor de RNPT T desde o nascimento até a idade corrigida de termo e comparar ao de recém-nascidos de termo (RNT) ao nascer. MÉTODOS: Foi realizado um estudo de coorte, prospectivo, com 29 RNPT Te 88 RNT de 4 hospitais credenciados à rede pública de saúde no município de Cuiabá/MT. OS RNPT T foram submetidos à avaliação motora através do Test of Infant Motor Performance (TIMP) ao nascer, realizaram US de crânio nas duas primeiras semanas de vida e repetiram o TIMP a cada duas semanas até a idade equivalente ao termo, bem como as medidas de peso, comprimento e perímetro cefálico. Ao termo, foi realizada uma avaliação neurológica pelo método de Dubowitz. Os RNT foram submetidos à avaliação motora pelo TIMP e neurológica de Dubowitz ao nascer. ANÁLISE ESTATÍSTICA: O tamanho da amostra definiu 29 crianças no grupo RNPT T, considerando um poder de teste de 80% e nível de significância de 5%. As análises basearam-se nos testes Exato de Fisher e Qui Quadrado e para comparação das variáveis quantitativas, os testes t de Student para duas amostras pareadas e teste t de Student para duas amostras independentes. Para análise dos fatores preditores do TIMP ao T foi realizada Regressão Múltipla Linear. RESULTADOS: Dos 29 RNPT T avaliados, 23 (79,3%) apresentaram US de crânio dentro da normalidade, 2 (6,9%) hemorragia intracraniana (HIC) grau I e 4 (13,8%) HIC grau I bilateral. O escore total do TIMP aumentou significativamente a partir de 38 - 39 semanas no grupo RNPT T (51,9 ± 5,8 às 34-35 sem, 53,6 ± 6,4 às 36-37 sem, 57,7 ± 7,3 às 38-39 sem e 62,6 ± 5,2 às 40 sem) (p < 0,05). As médias dos escores do TIMP de RNPT T em idades equivalentes às dos RNT ao nascer foram, às 38- 39 sem, de 57,7 ± 7,3 e 59,8 ± 6,4 e, às 40 sem, de 62,6 ± 5,2 e 61,7 ± 5,0,respectivamente, sem diferenças estatísticas entre estes. Por análise de regressão múltipla linear foram identificados a idade materna e o perímetro cefálico como preditores do TIMP em RNPT T em idade equivalente ao termo. Não foram encontradas diferenças ao comparar os escores das avaliações neurológicas pelo método Dubowitz de RNPT T aos de termo ao nascer. CONCLUSÃO: RNPT T de baixo risco podem apresentar evolução motora com aumento significante a partir de 38-39 semanas pós-termo, alcançando desempenho motor em idade equivalente ao termo, semelhante ao de RNT ao nascer. A idade materna e o PC foram identificados como preditores do escore do TIMP em RNPT T à idade corrigida de termo / INTRODUCTION: Reports on the motor development of extremely preterm infants are frequent in the literature, but little is known about the development of late preterm infants (LPI). OBJECTIVES: To analyze the motor development of LPI from birth until term-corrected age, and compare with that of term infants (TI) at birth. METHODS: A cohort study was performed, in which the Test of Infant Motor Performance (TIMP) was administered to 29 LPI at birth and repeated every two weeks until term-corrected age, as well as the anthropometric measures of weight, length and head circumference. A cranial ultrasound (US) in the first two weeks of age and a Dubowitz neurological assessment were administered to LPI at term corrected age. The TIMP and the Dubowitz neurological examination were administered to TI at birth. STATISTICAL ANALYSIS: The sample size was defined as 29 LPI, considering a test power of 80 % and a significance level of 5. Qualitative variables were compared using the Fisher exact test and Chi Square and Student\'s t test for two samples and paired Student\'s t test for two independent samples for quantitative variables. The multiple linear regression was performed for analysis of predictors of TIMP at term time. RESULTS: Among the 29 LPI evaluated, 23 (79.3%) had a cranial US within normal limits, 2 (6.9%) intracranial hemorrhage (ICH) grade I, and 4 (13.8%) bilateral ICH grade I. The mean TIMP score and standard deviation of LPI was 51.9 ± 5.8 at 34-35 weeks and 62.6 ± 5.2 at 40 weeks. There was a significant increase at 38-39 weeks in the LPI group (p < 0.05). There were no significant differences in the motor evaluations between LPI at the age equivalent to TI at birth (38-39 weeks and 40 weeks). The growth of LPI until term was adequate in relation to Alexander curve. After multiple linear regression we found that maternal age and head circumference were predictors of TIMP in LP at term age. No differences were found when comparing the scores of neurological assessments by Dubowitz between LPI and T infants. CONCLUSION: Low risk LPI presented a gradual progression of motor development until the term-corrected age, but differences with TI at birth were not detected. Maternal age and head circumference were identified as predictors of TIMP score at term in LPI

Objetivo: Avaliar as lesões placentárias encontradas em gestantes com SAF e correlacionar com as intercorrências na gestação e repercussões perinatais. Casuística e Método: Foram acompanhadas 72 gestantes com diagnóstico confirmado de SAF, excluídas gestações gemelares e fetos mal-formados. Colhida placenta para análise histológica. O grupo SAF foi distribuído em três subgrupos baseando-se na história clíncia prévia e títulos de aCL e aL, e o risco de desenvolver trombose e insuficiência placentária na gestação, a saber: moderado, A(n=20), alto risco, B(n=37) e alto risco C(n=15). As pacientes foram tratadas com AAS 100mg/dia, suspensa com 36 semanas, e heparina, cuja dose era modificada de acordo com alterações na dopplervelocimetria obstétrica. Anotadas as intercorrências materno-perinatais e os achados no estudo anátomo-patológico das placentas com a aplicação de protocolo terapêutico. Um grupo de 32 gestantes normais serviu de controle. No subgrupo A, as pacientes não apresentavam colagenoses, outras trombofilias nem trombose prévia. No subgrupo B, 17 (46%) tinham LES;15(40%) fenômeno de Raynaud; 13(35%) toxemia; 12(32%) trombose prévia; nove (24,3%) outras trombofilias associadas e sete (19%) HAC. No subgrupo C, 14(93%) tinham tido trombose anterior, 4 (26,6%) LES e 2 (13,3%) outras trombofilias. As perdas fetais prévias eram 86,8%, 83% e 82,7% para subgrupos A, B e C, respectivamente. A média de início pré-natal foi de 11,8 semanas sem predominância entre os grupos. O início de AAS e heparina foi em média de 12,3 e 14,5 semanas de gestação respectivamente, igual nos subgrupos. Resultados: 1. As principais complicações maternas na média geral, foram: TPP (49,3%) e toxemia (25%). 2. Os resultados perinatais apresentaram: partos prematuros 44%; ILA diminuído 41%; SFA 40%; RCF 34%; oligoâmnio 31%.(1) e (2) semelhantes entre os subgrupos e com significância estatística com o grupo-controle. 3. A idade gestacional no parto foi em média de 35,8 semanas, e peso fetal 2493g, sem diferença estatística entre os subgrupos e grupo-controle. 4. Na análise microscópica predominou infartos com 60% das placentas afetadas, correlacionadas com alta incidência de resultados adversos nas gestações, assim como hiperplasia da camada média de ATV, 44,6%, com predomínio de RCF (60%) e prematuros (80%) no subgrupo C, necrose fibrinóide do trofoblasto com predomínio de ILA diminuído (60%) no subgrupo B, deposição maciça de fibrina perivilosa com predomínio de SFA (100%) no subgrupo A, vasculopatia trombótica fetal com predomínio de SFA (100%) e prematuros (75%) no subgrupo A e RCF (77%) no subgrupo B. Todas as lesões com significativa estatística em relação ao grupo-controle. Entre os subgrupos, a deposição maciça de fibrina perivilosa apresentou estatística significativa no subgrupo C em relação aos demais. 5. Conclusões: O protocolo terapêutico foi eficaz, porém ainda é elevado o índice de morbidades na gestação.A alta incidência de infartos e outras complicações trombóticas na placenta confirmam a agressão placentária e a necessidade de adequação nos protocolos de anticoagulação / Objective: Evaluate the placental injuries found in pregnant women with SAF and correlate with the morbidity in pregnancy and fetal repercussions. Methods: 72 pregnant women with SAF diagnosis were followed, except the twin pregnancies and inadequate formed fetus. Gathered placenta to histological examination. The SAF group was distributed in three subgroups based on the previous clinic history, aCL and aL titles, risk of thrombosis development and the placentary insuffiency in pregnancy to know: moderated, A (n=20); high risk, B (n=37) and even higher risk, C (n=15). The patients were treated with AAS 100mg/day, suspended within 36 weeks and enoxaparin which portion was modified according to the fetal placental circulation alteration on obstetric dopplervelocimetria. The outcome of pregnancy and placental pathological findings studies with the application of the therapeutic protocol were noted down.32 normal pregnant women were the control group. In subgroup A the patients did not presented any disease colagen or heritable thrombophilia.In subgroup B,17(46%) pacients presented LES; 15(40%) Raynaud phenomena; 13(35%) preeclampsia; 12(32%) had previous thrombosis; nine(24.3%) had other thrombophilia and seven(19%) HAC. In subgroup C, 14 (93%) pacients presented previous thrombosis; 4(26%) LES; 4(26%) HAC; 3(20%) preeclampsia; 3(20%) Raynaud phenomena and 2(13.3%) others thrombophilia. The previous fetus losses were 85%, 80% and 79% to subgroups A, B and C respectively. Prenatal started around 12 weeks with no advantage among the groups. Introduction of AAS and enoxaparin was 12 and 14 weeks respectively the same in subgroups. Results: 1. The main maternal complications in general were: TPP (49%) and toxemia (25%). 2. The fetal results presented: 44% early childbirth; 41% reduced ILA; 40% SFA; 34% RCF; 31% oligohydramnios. (1) e (2) similar between the subgroups and expressive statistic with the control group. 3. The pregnant age was in avarage 35,8 weeks with fetus weigh 2493g with no statistic differences between the subgroups and the control group. 4. In the microscopy analysis predominated infarcts with 60% of the placentas affected, correlated with the high incidence of adverse results in pregnancies, so as 44,6% reduction or obliteration of fetal stem vessels by mural hyperplasia; 60% RCF predominance and 80% early childbirth in subgroup C, fibrinoid necrosis trophoblast with reduced ILA predominance (60%) in subgroup B, massive perivillous fibrin deposition with SFA predominance (100%) in subgroup A, fetal thrombotic vasculopathy with SFA predominance (100%) and early birth (75%) in subgroup A and RCF (77%) in subgroup B. All the placental injuries with statistics significance related to the group control. Among the subgroups the massive perivillous fibrin deposition presented statistic significance in the subgroup C related to the others. Conclusions: The therapeutic protocol was effective, but is still high the morbidity indices among the pregnancies. The high incidences of infarcts and other thrombotic complications in the placenta confirm the placental aggression and the necessity of the adequation in the anticoagulation protocols

A prematuridade se caracteriza por ser qualitativamente distinta do nascimento de termo, em função das intercorrências neonatais, do impacto do período de permanência na incubadora e da influência da ação da gravidade no desenvolvimento postural, do equilíbrio e da locomoção. Este estudo teve como OBJETIVOS: 1- comparar a coordenação motora axial de lactentes pré-termo (RNPT) saudáveis, com a de lactentes de termo (RNT), por meio dos escores da Alberta Infant Motor Scale (AIMS), segundo a idade cronológica (ICr) e corrigida (ICo), a partir do termo até a utilização da marcha independente como principal meio de locomoção; 2- verificar período de aquisição, entre RNPT e RNT, segundo ICo, de 7 itens avaliados pela AIMS (transição de quatro apoios para sentado; engatinhar; segurar o(s) pé(s) em supino; sentar-se independente; transição de sentado para quatro apoios; ficar em pé sem apoio; marcha independente); 3- determinar a influência de variáveis biológicas e sóciodemográficas para obtenção da marcha em RNPT. MÉTODOS: estudo coorte, prospectivo, observacional, mensal e comparativo entre 101 RNPT (grupo de estudo) e 52 RNT (grupo controle). Foram ajustados modelo de regressão beta e equações de estimação generalizada para curvas de ICr e ICo, a fim de comparar a média mensal dos escores entre os grupos. Para comparar as idades de aquisição dos sete itens da AIMS entre os RNT e RNPT, foram utilizadas estimativas de Turnbull da distribuição da idade e modelo de taxa de falhas proporcionais de Cox para censuras intervalares. Para análise estatística dos resultados das médias mensais entre os grupos e as idades de aquisição dos itens, recorreu-se à construção de intervalo de confiança (IC). Para análise das variáveis prognósticas no tempo da aquisição da marcha nos RNPT, análise de sobrevivência para censuras intervalares e modelo de regressão Weibull foram utilizados. O nível de significância considerado foi < 5%. RESULTADOS: Finalizaram o estudo 77 RNPT e 49 RNT. Os escores segundo ICr dos RNPT demonstraram ser estatisticamente inferiores em relação aos dos RNT. Segundo a ICo, os escores dos RNPT tornaram-se equivalentes aos dos RNT, não demonstrando diferença estatística significativa. Dos 7 itens analisados, somente em pé sem apoio e a marcha foram adquiridos mais tardiamente pelos RNPT. As variáveis biológicas com influência significante no tempo de aquisição da marcha foram: peso ao nascimento (PN), estatura ao nascimento (EN) e permanência no hospital após nascimento. CONCLUSÃO: A coordenação motora axial dos RNPT deve ser avaliada segundo ICo para não ser subestimada. A aquisição da marcha e a posição em pé sem apoio se desenvolvem mais tardiamente nos RNPT. Além disto, a aquisição da marcha em RNPT foi tão mais tardia quanto menor o PN e EN, assim como o longo período de internação após o nascimento retardaram a marcha nos RNPT. / The prematurity characterizes to be qualitatively different from term delivery, due to neonatal morbidities, impact of the long period in the incubator and the influence of gravidity in the postural development. This study has as OBJECTIVES:1- to compare the gross motor development in healthy preterm infants (PT) with term infants (T), using Alberta Infant Motor Scale (AIMS) scores, according to corrected and chronological ages, from term to walking independently; 2- To compare the age attainment of seven AIMS items, according to corrected age (four-point kneeling to sitting; reciprocal creeping; hands to feet in supine; sitting independently; sitting to four-point kneeling; stand alone; early stepping) between PT and T infants; 3- To study biologic and sociodemographic factors that affect walking attainment in PT. METHODS: cohort, prospective, observational monthly and comparative study between 101 PT and 52 T. In order to compare descriptively mean monthly scores, beta regression models and general estimated equations were used to adjust the chronological and corrected age graphics and for statistics purposes, the confidence interval of monthly mean scores were used. Turnbull estimation of age distribution and Cox´s proportional hazards model were used to compare the age in each seven items between groups. For prognostic factors of age walking attainment in PT, methods of Kaplan-Meyer and Weibull regression model were used. The level of significance was considered significant, if p < 5%. RESULTS: 77 PT and 49 T infants finished the study. Chronological age scores of PT were statistically lower in comparison with T scores. According to corrected age, PT monthly mean scores were not statistically different from T scores. Of seven analysed items, only standing alone and early stepping were attained later in PT infants. The variables that seemed to influence statistically in age of walking attainment were: birth weight and stature and duration of hospitalization. CONCLUSION: Gross motor development of PT infants should be assessed according to corrected age, in order not to be underestimated. The both milestones standing alone and early stepping developed later in PT infants. The lower the birth stature and weight were, the longer it took for the PT infants to attain walking, while the longer the PT newborns stayed hospitalized, the later they started walking.

A necessidade de usar a idade corrigida nos recém-nascidos pré-termos (RNPTs) ao avaliar o desenvolvimento motor (DM) é um assunto controverso. Para verificar a necessidade de usar a correção de idade nos primeiros seis meses de idade corrigida, 43 RNPTs foram analisados, por meio da Alberta Infant Motor Scale (AIMS), como um todo e divididos em dois grupos segundo a idade gestacional. Os resultados sugerem que há diferença estatística significativa no DM, quando se utiliza a idade cronológica. Portanto, há necessidade de corrigir a idade, para não subestimar o DM dos RNPTs, classificando-os como atrasado / The need of using the corrected age in pre-term infants (PT) to assess the motor development (MD) is a controversial issue. To verify the need of using the corrected age, during the first six months the corrected age, 43 PT were analysed according to Alberta Infant Motor Scale (AIMS), as one group and as divided into two groups according to gestational age. The results suggested that there is statistically significance in the MD, when the chronological age is used. In conclusion, there is the need of correcting the age, in order not to under-estimate the MD of PT, classifying them as delayed

INTRODUÇÃO: A prematuridade é uma condição do nascimento que ocorre anteriormente a 37 semanas completas de gestação, e é considerada um fator de risco biológico ao desenvolvimento infantil. Nos primeiros anos de vida, crianças nascidas pretermo podem apresentar alterações no desenvolvimento da linguagem e em habilidades cognitivas, como a memória. Essas dificuldades podem perdurar e se manifestar ao longo do crescimento, nas fases pré-escolar e escolar. Devido a isso, prematuros são acompanhados em programas de seguimento ambulatorial, nos quais são utilizados testes de triagem para identificar riscos para atraso no desenvolvimento. O presente estudo investigou se pré-escolares nascidos pretermo (Grupo Pesquisa/GP) apresentavam indicativos de dificuldades de linguagem em instrumento de triagem e em testes padronizados de vocabulário e memória de curto prazo verbal; comparou seu desempenho ao de pré-escolares nascidos a termo (Grupo Controle/GC); e secundariamente verificou a associação entre os resultados obtidos no instrumento de triagem com os dos testes diagnósticos. MÉTODOS: Participaram do estudo 40 crianças de ambos os gêneros e com faixa etária entre 4 a 5 anos, divididas igualmente em dois grupos, com base na idade gestacional ao nascimento. Todas apresentavam desenvolvimento neuropsicomotor adequado para a idade e não possuíam alterações sensoriais, neurológicas e genéticas. Os grupos foram pareados pela idade, nível socioeconômico e escolaridade materna, e caracterizados quanto ao desenvolvimento fonológico por meio de teste padronizado. A avaliação experimental foi composta por testes padronizados de vocabulário expressivo, memória de curto prazo verbal e por um teste de triagem do desenvolvimento. RESULTADOS: Na comparação entre o desempenho dos grupos nas tarefas experimentais, não houve diferença entre eles no vocabulário expressivo, mas o GP apresentou desempenho inferior ao GC e maior índice de desempenho inadequado na tarefa de memória de curto prazo verbal. No teste de triagem do desenvolvimento, o GP foi classificado como Suspeito ou risco ao desenvolvimento com maior frequência do que o GC no desempenho geral. No subteste de linguagem, os prematuros também foram classificados como inadequados com maior frequência que os sujeitos do GC. Não houve associação entre a classificação do desempenho do GP no instrumento de triagem e nos demais testes experimentais, tanto para o desempenho geral, quanto para o desempenho no subteste de linguagem. CONCLUSÕES: Confirmou-se a hipótese de que pré-escolares prematuros apresentariam indicativos de dificuldades detectados por instrumento de triagem. Na habilidade lexical foi observado que o desempenho de crianças prematuras pode ser semelhante ao de crianças nascidas a termo, e na habilidade de memória de curto prazo verbal foram observados prejuízos quando os grupos foram comparados. É possível que as dificuldades observadas na habilidade de memória possam impactar negativamente a expansão lexical ao longo do desenvolvimento. Por fim, não foi observada associação dos resultados obtidos no instrumento de triagem com os dos testes de avaliação / BACKGROUND: Premature labor is a condition of birth that happens at fewer than 37 weeks gestational age and is considered a biological risk factor to child development. In the first years of life, preterm infants may present changes in language development and cognitive abilities, such as memory. These difficulties may last and manifest during growth, in preschool and school-ages. Because of that, infants followed at preterm infant follow-up outpatient clinics, where screening tests are carried out to identify risks of developmental delay. This study investigated whether preschool infants born premature (Experimental Group/EG) presented indicators of language difficulty in screening tool and in vocabulary standardized tests and verbal short-term memory; compared their performance to preschool full-term infants (Control Group/CG), and finally verified the association between results obtained from screening tool and diagnostic tests. METHOD: It took part of the study 40 male and female individuals aged 4 to 5 years, assigned equally to two groups, based on gestational age at birth. They all presented regular neuropsychomotor development for their age and did not have any sensorial, neurological or genetic alterations. The groups were paired by age, socioeconomic status and their mother\'s educational level, and characterized by phonological development according to standardized test. The experimental evaluation consisted of standardized tests on expressive vocabulary, verbal short-term memory and a development triage test. RESULTS: In comparison of performance between the groups in experimental tasks, no difference was in the expressive vocabulary was observed; however, the EG showed poorer performance compared to CG and higher rates of poor performance on the verbal short-term memory test. On the development triage test, the EG was classified as suspect or risk to development more often than CG in general performance. On the language subtest, preterm infants were also classified as unappropriated more frequently than CG individuals. There was no association between EG performance classification on the screening tool and the other experimental tests, either on general performance test or language performance subtest. CONCLUSION: It was confirmed the hypothesis that preschool preterm infants would present signs of difficulty detected by the triage tool. Regarding lexical ability, it was observed that preterm infant\'s performance may be similar to full-term infants, and in the verbal short-term memory ability it was observed drawbacks when groups where compared. It is likely that the observed difficulties on memory ability may negatively interfere the lexical expansion throughout development. Finally, it was not observed any association between the results obtained from screening tool and evaluative tests
