Incidence of gynaecological cancers and overall and cause specific mortality of grand multiparous women in Finland

Hinkula, M. (Marianne) 21 February 2006 (has links)
Abstract The aim of this population-based cohort study was to evaluate the incidence and relative risk ratios of gynaecological cancers and the mortality of women with at least five children (GM women) compared to the average of Finnish women. We linked together the data of the Population Register (1974–1997), the Finnish Cancer Registry and the national cause-of death files of Statistics Finland (1974–2001) by using a personal identification code. The study population consisted of 86 978 GM women (1974–1997), including 3 752 women with at least 10 children (GGM women). Altogether 7 604 cancer diagnoses and 18 870 deaths were recorded. The incidence (SIR) of breast (0.55, 95% CI 0.52–0.58), endometrial (0.57, 95% CI 0.52–0.63) and ovarian cancer (0.64, 95% CI 0.55–0.73) decreased, and that of cervical cancer (1.13, 95% CI 0.98–1.29) increased in GM women. In multivariate analysis, the increase in parity from five to eight increased the protection against breast and endometrial cancer, but not in ovarian or cervical cancer. A young age at first birth decreased the breast cancer risk, while an older age at first birth decreased the risk for endometrial and cervical cancer. A short premenopausal delivery-free period and a long birth period were risk reducers in women who contracted endometrial cancer after menopause. The mortality (SMR) of breast (0.64, 95% CI 0.59–0.69), endometrial (0.68, 95% CI 0.56–0.80), ovarian cancer (0.68, 95% CI 0.60–0.75) as well as for dementia (0.80, 95% CI 0.72–0.84) decreased. The SMR of kidney (1.38, 95% CI 1.21–1.56) cancer increased in the GM group. The SMR of ischemic heart diseases (1.10, 95% CI 1.08–1.13) and diabetes mellitus (1.42, 95% CI 1.29–1.55) increased. The overall SMR of GM women was 5% less than expected (95% CI 0.94–0.95; deficit 949 deaths), but among GGM women it coincided with the national average (1.01, 95% CI 0.93–1.08). Multiparity affected the spectrum of diseases and causes of death in a specific way: the pregnancy-specific hormonal milieu is responsible for the low SIR and SMR of hormone-dependent cancers, and increased body weight is lightly responsible for the high SMR of cardiovascular and metabolic diseases. These observations advocate for delivering the first child at an age younger than 30 years and to start measures for careful weight control not only during and after pregnancies but even later and permanently.

Prevalence and pattern of injuries among players at the university of the Western Cape volleyball club

Abdelnour, Hassan January 2008 (has links)
Magister Scientiae (Physiotherapy) - MSc(Physio) / In addition to football and basketball, volleyball has become a very popular sport globally over the last 30 years. The International Federation of Volleyball represents about 150 million players in approximately 170 countries. While a large body of research has been conducted regarding the nature and prevalence of volleyball injuries internationally, very little has been done locally or on the African continent to assess the status of injuries incurred at professional or amateur levels. The aim of this study is to determine the prevalence of injuries sustained by professional volleyball players of a club in the WPVU in one season. An exploratory, descriptive, nonexperimental approach was used for this study on 42 volleyball players at the University of the Western Cape Volleyball Club. A self–administered questionnaire that was based on a questionnaire used in a Dutch national volleyball study was used in the present study. A response rate of 89.4% was obtained. The collected data were captured and analysed by means of the Statistical Package for Social Science version 14.0 (SPSS). The associations between variables were evaluated by means of the chi-square test and a 5% level of significance was used. The results were displayed using tables, bar chart, and pie chart. Most of the volleyball players sustained one or more injuries in the season, giving a prevalence rate of 88.1%. The incidence rate was 1.2 injuries per player. Injuries prevalence was higher among male players 54.1% than female players 45.9%. Among the injured players, ankle and knee injuries showed the highest injury prevalence with 25.5% for each followed by 19.6% for shoulder injuries. The study revealed 69.2% injury prevalence with a higher significance (p=0.04) that players who are injured in the ankle were in contact. Half of the injuries (50%), which occurred gradually, were prevalent in the shoulder, followed by the knee (28.6%), then the ankle and fingers (14.3%). Players in the left and right front row were significantly (p=0.008) more prone to be injured during spiking. Awareness programmes highlighting prevention strategies and physiotherapy intervention are required for coaches and players at the University of the Western Cape Volleyball Club to assist in the prevention of volleyball injuries

Public sector spending in Nigeria: implications for poverty, demographic changes and millennium development goals target

Kanayo, Ogujiuba January 2015 (has links)
Philosophiae Doctor - PhD / Over the last two decades, budgetary allocations to both the Health and Education sectors have been on the increase in Nigeria, while a counter-factual feedback on its effects for various economic groups and distributional effect for different population households has not been defined and well known. The resultant effect has been gross inefficiency and sub-optimality in terms of observed outcomes of the fiscal framework. In-addition, there have been a continuous quest by the citizenry for increased allocations to these sectors because of its supposed impact on the poverty index and standard of living. Although this is a compelling reason, but what is worrisome and equally troubling, is that the increasing incidence of poverty and expanding inequality in the Nigerian society have not mitigated, despite the scaling up of funding on the social sectors. Furthermore, the current level of socioeconomic development in Nigeria is not in tandem with the distributive outcome targets set by the 2004 reforms. Thus, understanding the current structure of poverty in Nigeria as well as beneficiaries of public sector spending provides a sound basis for tackling inequality and redesigning the current pro-poor frameworks. However, our analysis is focused on the distributional spread of beneficiaries from services and the counterfactual reciprocity of expenditure benefits rather than measuring the exact value to recipients of government-sponsored services. Our research methodology used the 2004 Nigerian Living Standard Survey; 2010 Harmonized Nigerian Living Standard Survey; Recent Cros-sectional data (2014) in South East Nigeria and secondary sources. Econometric methods (Error Correction Method); Marginal Odds estimation techniques, Concentration Curves and Ordered Logistic Regression were used for our analysis. Statistical and Econometric Software’s (E-Views; SPSS; DAD and STATA) were used for estimations. Econometric results showed misalignments between population dynamics and public sector expenditure on education, health and economic services. The government consumption expenditure was not sensitive to demographic changes. The derived adjustment coefficients of -1.38, -1.51 and 0.51 respectively, for education, health and economic services indicate huge gaps in terms of what optimal spending should have been, giving the population dynamics. Our benefit incidence analysis indicates that substantive gains have been made at the primary education and health care level, at the state level for SE Nigeria but there is a gross misapplication of funds at the secondary and tertiary levels of both education and health sectors. Results show that the state governments’ is subsidizing the rich at the levels of both secondary and tertiary for education and health care. In addition, country wide results indicate that apart from public primary education and health care for urban residents, no other level of social service was absolutely progressive in general terms, by gender or by location while the tertiary level of both services were regressive as shown by the 2010 survey results, in comparism to the 2004 survey results. Using the Ordered Logistic Regression, our result inclines to the lifecycle hypothesis which maintains that poverty oscillates depending on the age. At a younger age, it tends to be on the high side and decreases during the middle ages and increases with age. Our results discards the feminization of poverty general framework that women or female headed households are more prone to poverty due principally to low education and lack of opportunity to own assets such as land amongst others. This wasn’t the case for the South East Region of Nigeria. Estimates indicate that education status, health status and access to health facilities affected the category of welfare of head of households and invariable, the entire household. In general, our analysis shows misalignment of social expenditure for various population groups, both at the federal and state levels; making doubtful the realization of basic MDGs. Nigeria has to combine growth policies and assuring that demographics count, with the poor fully participating in economic development. Also, the need for a refocusing in resource allocation taking into cognizance gender dimensions cannot be overemphasized. A general re-allocation of spending going to females and the poorer households would lead to improvement in gender equality and health status of women and children. Expediting actions towards qualitative education will lead directly to an acceleration of many of the other MDGs, especially those focusing on the reduction of poverty and inequality. To attain MDG targets (post 2015) within a shorter period of time, there is the need to improve the quality of social infrastructure and services. Furthermore, research should be focused on improving knowledge and understanding of what policies, technologies and investments matter for sustained growth in the country. This will create the much needed multiplier effect on other aggregates. The degree to which the poor participate in the growth process and share in its proceeds matter; both in the pace and pattern of growth. It is therefore important to have categorization of the population into economic groups when formulating a developmental framework for poverty reduction programmes. The study recommends sequencing of interventions, strengthening of institutions and other several interrelated areas to attain effectiveness of public sector spending.

Banana streak badnavirus (BSV) in South Africa : incidence, transmission and the development of an antibody based detection system

Meyer, J.B. (Jacolene Bee) 09 February 2007 (has links)
Various research efforts have focused on Banana streak badnavirus (BSV), the causal agent of banana streak disease (BSD), since the discovery of endogenous sequences of the virus in the nuclear genome of several Musa (banana and plantain) species. In vitro propagation of Musa was identified as one of the main activation triggers of integrated BSV sequences to cause systemic (episomal) BSD. This was especially observed in B genome-containing tetraploid hybrids. Although, the South African banana industry is based on Cavendish varieties, some plantations with tetraploid hybrids have been established. In order to investigate the occurrence of episomally expressed BSV, a survey was done in the Kiepersol area of South Africa and episomal BSV was detected in six out of seven locations sampled. No episomal BSV was detected in the Cavendish cultivars sampled in close proximity to BSV infected cultivars. To determine the risk of vector-assisted spread of endogenous BSV, which has become episomally activated after tissue culture, transmission studies with local mealybug species (Planococcus citri (Risso), P. ficus (Signoret), Dysmicoccus brevipes (Cockerell) and Pseudococcus longispinus (Targioni-Tozzetti)) were conducted under controlled conditions. Virus-free FHIA-21 was multiplied in vitro and resulting progeny with, putatively episomally activated BSV, served as sources for mealybug-assisted transmissions to Cavendish. Activated, episomal BSV was transmitted by three mealybug species to Cavendish. Transmission with P. ficus was demonstrated for the first time. Limited antiserum stocks against BSV occur worldwide and detection of the virus remains crucial for the safe movement of Musa germplasm between continents. Antiserum is needed in order to detect the episomal form of the virus that causes BSD. Using conventional immunization methodology, antisera against a wide spectrum of BSV isolates were produced. Twenty diverse BSV isolates were characterized by IC-PCR and selected as sources for the production of the polyclonal antiserums in two animal species. An effective triple antibody sandwich (TAS) enzyme linked immunosorbent assay (ELISA) system; able to detect various serologically different species of BSV was developed. BSV was screened with a synthetically manufactured phage displayed antibody library; however, no satisfactory polyclonal or monoclonal antibodies were obtianed in using this approach. / Dissertation (MSc (Microbiology))--University of Pretoria, 2007. / Microbiology and Plant Pathology / unrestricted

Incidence of schizophrenia and associations of schizophrenia and schizotypy with early motor developmental milestones

Filatova, S. (Svetlana) 05 December 2017 (has links)
Abstract Schizophrenia is a complex mental health disorder and its etiology can be investigated based on different theoretical prerequisites. The present thesis examines schizophrenia from the neurodevelopmental and psychosis continuum perspectives. Neurodevelopmental theories of schizophrenia see abnormalities in the developing nervous system as early predictors of vulnerability to the disease. Schizophrenia can be seen also as a progressive disorder and a continuum of symptomatology from personality traits (schizotypy) to full-blown schizophrenia. The aim of the present thesis is to study incidence of schizophrenia; prevalence of schizotypy; and associations between schizophrenia and schizotypy with early motor developmental milestones. The research design includes prospective cohort studies and systematic review, and meta-analysis. In two successive Northern Finland Birth Cohorts (NFBC) studies, 20 years apart (1966 and 1986), the incidence of schizophrenia remained the same, but the incidence of other psychoses and therefore all psychoses was higher in NFBC 1986. In NFBC 1966, mean schizotypy scores were among the lowest and the highest scores among 24 general population studies. When early motor developmental milestones were investigated in the meta-analyses (3 to 5 studies), a significant small effect size for walking, sitting, and standing unsupported was found with respect to adult schizophrenia. When schizotypy outcome was studied in the NFBC 1966, later achievement of turning from back to tummy, touching thumb with index finger, standing up, sitting unsupported, and walking with support were found to be associated with an increase in schizotypy scales and varied somewhat by gender. To conclude, there have been changes in the incidence of all psychoses but not in schizophrenia between the two NFBCs. This is in line with other studies on the trends of incidence of psychoses, which highlights the role of changes in diagnostic systems and practices that can influence rates. In this project, mean schizotypy scores were both among the highest and the lowest estimates in the studies on schizotypy in the general population. Early motor developmental milestones were both predictors of schizophrenia and schizotypy, and thus this finding supports both the neurodevelopmental and psychosis continuum approaches to the aetiology of schizophrenia. / Tiivistelmä Skitsofrenia on monimuotoinen mielenterveyden häiriö, jonka etiologiaa voidaan tutkia erilaisissa teoreettisissa viitekehyksissä. Tämä väitöskirja tutkii skitsofreniaa neurologisen kehityksen ja psykoosin jatkumon näkökulmista. Skitsofrenian neurokehitykselliset teoriat pitävät kehittyvän keskushermoston poikkeavuuksia varhaisina skitsofrenian alttiuden ennustajina. Skitsofreniaa voidaan pitää myös progressiivisena sairautena ja oireiden jatkumona persoonallisuuden piirteistä (skitsotypaalisuudesta) täysimittaiseen skitsofreniaan. Tämän väitöskirjatutkimuksen tavoitteena on tutkia skitsofrenian ilmaantuvuutta, skitsotypaalisten piirteiden yleisyyttä ja skitsofrenian ja skitsotypaalisten piirteiden yhteyttä varhaiseen motoriseen kehitykseen. Tutkimusasetelmina ovat prospektiiviset syntymäkohortit, systemaattinen katsaus ja meta-analyysi. Kahdessa peräkkäisessä 20 vuoden välein kerätyssä Pohjois-Suomen syntymäkohortissa (1966 ja 1986) skitsofrenian ilmaantuvuus pysyi samana, mutta muiden psykoosien ja siten kaikkien psykoosien ilmaantuvuudet olivat korkeampia vuoden 1986 syntymäkohortissa. Vuoden 1966 syntymäkohortissa negatiivisen skitsotypaalisuuden piirteet olivat korkeita ja positiivisen skitsotypaalisuuden piirteet alhaisia verrattuna 24 muuhun väestöaineistoon. Varhaisen motorisen kehityksen ja aikuisiän skitsofrenian välistä yhteyttä tutkittiin meta-analyysin (3–5 tutkimusta) avulla. Tilastollisesti merkitsevä pieni negatiivinen yhteys löytyi aikuisiän skitsofrenian ja kävelemään, istumaan ja seisomaan oppimisen välillä. Pohjois-Suomen vuoden 1966 syntymäkohortissa skitsotypaaliset piirteet liittyivät hitaampaan vatsalleen kääntymisen, peukalo-etusormi otteen, seisomisen, tuetta istumisen ja tuen kanssa kävelemisen oppimiseen. Näissä yhteyksissä oli vaihtelua tutkittavan sukupuolen mukaan. Yhteenvetona voidaan todeta, että psykoosien ilmaantuvuus on kasvanut Pohjois-Suomen syntymäkohorteissa, mutta skitsofrenian ei. Tämä on linjassa aikaisempien tutkimusten kanssa. On kuitenkin huomioitava myös diagnostisten järjestelmien ja käytäntöjen merkitys näiden muutosten arvioimisessa. Varhainen motorinen kehitys ennusti sekä skitsofreniaa että skitsotypaalisia piirteitä. Havainto tukee sekä neurokehityksellistä että psykoosin jatkumoon liittyvää lähestymistapaa skitsofrenian etiologiassa.

Suicide in Addis Ababa : A Mixed Method Study of Incidence and Societal Views

Gebrehiwot, Kidane Ayele January 2017 (has links)
Introduction: Suicide is a global public health and social problem affecting the most productive age group, and the elderly. In Addis Ababa, despite high suicide rates there is no proper registration and certification that is meant for public health purpose. This study is conducted to look into the incidence and explore societal views towards suicide in Addis Ababa. Methods: Secondary data was collected from registers of Forensic Pathology Department at Menilik II Hospital and Homicide Crimes Investigation Unit at Addis Ababa Police Commission. Qualitative data was also collected from experts having experience in helping suicide victims.   Results: Between January 01 and December 31st 2015, 267 residents of Addis Ababa, majority of who are males, died due to suicide. Hanging being the most frequently used means, social isolation, mental illness, family conflict, economic problems and lack of religious commitment are perceived causes of suicide. Unavailability helping institutions and individual preference as to the method of suicide and individual nature of suicide are conditions that get the attention. While respect for social and religious values is considered as protective factors, the act of suicide is religiously criminal act. The victims of suicide include family and community members.   Conclusion: There is a need to consider policy and programmatic actions directed towards suicide prevention and control. In addition to conducting community wide research in suicide, it is important to preserve social and cultural values; institutionalize traditional family conflict resolution practices and strengthen mental health institutions. / <p>Enbart abstract.</p>

Incidência, fatores preditores e consequências do delirium no pós-operatório de cirurgia cardíaca em idosos / Incidence, predictive factors and complications of delirium in postoperative cardiac surgery elderly patients

Fatima Rosane de Almeida Oliveira 18 June 2015 (has links)
Delirium é um estado confusional agudo caracterizado por um distúrbio de consciência, alteração na cognição e curso flutuante ao longo do dia. É a complicação mais comum observada em idosos hospitalizados. É freqüente no pós-operatório de cirurgia cardíaca, e pode chegar a taxas tão altas quanto 73% em pacientes mais idosos. Pacientes com delirium apresentam maior risco de morte, demência e institucionalização, aumento do tempo de internação hospitalar e dos custos. Os objetivos deste estudo foram: 1) determinar a incidência do delirium no pós-operatório de cirurgia cardíaca em idosos; 2) identificar fatores predisponentes e precipitantes neste contexto; 3) avaliar a relação entre delirium e morbimortalidade por até 18 meses de seguimento. Este estudo foi observacional, prospectivo, tipo coorte, realizado no Hospital de Messejana no período de Setembro/2011 à Dezembro/2013. Foram estudados 173 pacientes com idade > 60 anos. Antes da cirurgia, os pacientes foram avaliados quanto à função cognitiva através do MEEM e TFV, e pelo CAM, para determinar a presença de delirium pré-operatório, motivo de exclusão do estudo. Foram registradas variáveis referentes aos dados demográficos, doenças prévias, medicações utilizadas, e calculado o risco de mortalidade cirúrgica para cada paciente através do EuroSCORE II. Resultados de exames pré-operatórios como ECG, ecodopplercardiograma, cateterismo cardíaco, Doppler de carótidas e exames laboratoriais também foram registrados. Durante a cirurgia, as variáveis avaliadas foram o tempo de CEC e clampeamento de aorta, duração da cirurgia e anestesia e uso de hemoderivados. Como variáveis pós-operatórias foram analisados o TIOT, tempo de permanência na UTI, presença de disfunção renal, hipoxemia. O delirium foi avaliado pelo CAM-ICU no pós-operatório. Para o desfecho composto foram registrados óbitos por todas as causas, infecções e IAM perioperatório identificados até a alta hospitalar ou 30 dias após a cirurgia. Os pacientes foram seguidos por um período de 12 a 18 meses e registrados eventos como óbitos, reinternações e demência, através de nova avaliação com MEEM e TFV. Após análise univariada foi realizada análise multivariada por regressão logística múltipla para identificar as variáveis independentes. A idade média dos pacientes foi 69,5 + 5,8. Cerca de 75,14% eram hipertensos e 39,88% eram diabéticos. A média do EuroSCORE II foi 4,06 + 3,86. Cerca de 30,06% eram analfabetos. A média do grau de escolaridade foi 3,05 + 3,08 anos. A incidência do delirium foi 34,1%. Em 70% dos casos, o delirium foi detectado nos dois primeiros dias após a cirurgia. Foram identificados o grau de escolaridade (OR = 0,81; IC 95% 0,71 - 0,92; p=0,002), HAS (OR = 2,73; IC 95% 1,16 - 6,40; p=0,021) e a presença de valvopatia mitral ( OR = 2,93; IC 95% 1,32 - 6,50; p=0,008) como fatores predisponentes independentes para delirium. Como fator precipitante independente foi identificado o tempo de internação na UTI com OR=1,18; IC 95% 1,07 - 1,30 e p=0,001. O delirium foi fator de risco independente para o desfecho composto com OR=2,35; IC 95% 1,20 - 4,58 e p=0,012, além do TIOT > 900 minutos (OR=2,50; IC 95% 1,30 - 4,80; p=0,006) após análise multivariada. Não houve relação entre delirium e óbito após alta hospitalar, demência ou taxa de reinternação durante o seguimento / Delirium is an acute and transient syndrome with features of inattention and global cognitive dysfunction over the time. Among elderly hospitalized patients is the most common complication. The postoperative cardiac surgery delirium occurs in 73% in older patients. Delirium patients, have prominent risk factors for dementia, institutionalization, death, hospital care and increased cost of healthcare. The aims of this study were: 1) to determine the incidence of postoperative cardiac delirium, focusing particularly on elderly individuals; 2) to identify the predisposing and precipitating factors of delirium; 3) evaluate the morbi-mortality associated with delirium in a follow up of eighteen months. A prospective observational cohort study (n=173) patients, aged >= 60 years, admitted at Heart and Lung Messejana\'s Hospital between September/2011 to December/2013. Before the surgery, the Mini-Mental Status Examination (MMSE) and Verbal Fluency Test (VFT) were administered to assess patient\'s cognitive functioning. The patients were screened for delirium using the Confusion Assessment Method (CAM). Patients were excluded preoperatively if they met criteria for delirium. Variables related to demographic data, previous diseases, medications were recorded and EuroSCORE II calculated the risk of surgical mortality for each patient. Results of preoperative tests, like ECG, echocardiography, cardiac catheterization, carotid Doppler ultrassound and laboratory tests were also recorded. During the surgery, variables were ECC (extracorporeal circulation) and aortic clamping time, duration of surgery and anesthesia, and blood products were also recorded. Postoperative variables analyzed were: the orotracheal intubation time (OIT), length of stay in the ICU, renal dysfunction and hypoxemia. The postoperative delirium was accessed by CAM-ICU. Mortality from any cause, infection and perioperative myocardial infarction, identified until hospital discharge or 30 days after surgery were predefined as the composite endpoint. During a follow up of 12 to 18 months, a new assessment using MMSE and VFT were held; events such as, deaths, readmissions and dementia were recorded. Multivariate analysis was performed by multiple logistic regressions to identify independent variables. Patients aged 69.5 ± 5.8. About 75.14% were hypertensive; 39.88% were diabetic. The mean EuroSCORE II was 4.06±3.86. About 30.06% were illiterate; an average 3.05 ± 3.08 years of school. In 70% of cases, delirium was detected at the first two days after surgery with an incidence of 34.1%. The degree of literacy (OR = 0,81; 95% CI 0,71 - 0,92; p=0,002), hypertension (OR = 2,73; 95% CI 1,16 - 6,40; p=0,021) and mitral valve disease (OR = 2,93; 95% CI 1,32 - 6,50; p=0,008) were independently associated with delirium. Longer ICU length of stay (OR=1,18; 95% CI 1,07 - 1,30; p=0,001) was also independently associated with delirium as a precipitation factor. Delirium was an independent risk factor for the composite outcome (OR = 2.35; 95% CI 1.20 - 4.58 and p = 0.012); OIT > 900 minutes (OR = 2.50; 95% CI 1.30 - 4.80; p = 0.006) after multivariate analysis. There was no relationship between delirium and mortality after hospital discharge, as well as, dementia or hospital readmission during follow up

Incidência de Salmonella spp. em caqui (Diospyrus kaki) e crescimento de S. Enteritidis na casca e na polpa dessa fruta / Incidence of Salmonella spp. in persimmon (Diospyrus kaki) and growth of S. Enteritidis on the peel and in the pulp of this fruit.

Ana Carolina Bortolossi Rezende 13 February 2008 (has links)
O consumo mundial de produtos frescos tem aumentado nos últimos anos, devido a preocupação da população com a saúde. Entretanto, a busca por uma alimentação mais saudável vem aumentando o risco de surtos de doenças veiculadas por frutas e hortaliças, tendo em vista, que estes alimentos são geralmente consumidos in natura. Embora qualquer patógeno possa ser um problema potencial nesses produtos, Salmonella spp. tem grande relevância em saúde pública. A contaminação potencial por esse patógeno em frutas, é possível devido a contaminação cruzada e falta de boas práticas agrícolas durante o cultivo, colheita, manuseio e distribuição. Nas frutas de baixa acidez, dentre as quais está o caqui, Salmonella spp pode ainda ter condições para sobreviver e se multiplicar. O caqui é uma fruta de relevante importância sócio-econômica, com crescente demanda para exportação, no entanto, o mercado importador está cada vez mais exigente em relação a segurança alimentar. No Brasil, não existem informações sobre a ocorrência de Salmonella spp em caqui, bem como, a respeito do comportamento desse patógeno na polpa e na casca dessa fruta. Desse modo, os objetivos do presente estudo foram: (1) verificar a incidência de Salmonella spp na superfície do caqui, (2) estudar a sobrevivência e multiplicação de S. Enteritidis na polpa e na casca dessa fruta armazenada a diferentes temperaturas de incubação. Para tanto, em 2005 foram coletadas 77 amostras de caqui Fuyu e 80 amostras de caqui Rama Forte no varejo na cidade de Campinas-SP e a mesma proporção no ano de 2006. Adicionalmente em 2006 também foram coletadas 134 amostras de caqui Rama Forte e 134 amostras de caqui Fuyu no CEAGESP, na cidade de São Paulo. A pesquisa para Salmonella spp foi realizada pelo sistema BAX®, que se baseia na reação da polimerase em cadeia (PCR). Os parâmetros de crescimento de S. Enteritidis (duração da fase lag, taxa de crescimento exponencial e tempo de geração) foram obtidos dos dados experimentais. Os resultados mostraram que das 582 amostras analisadas 5 (0,9%) foram positivas para Salmonella spp, indicando que condições sanitárias durante o crescimento no campo (água de irrigação, adubo, etc.), colheita, condições de transporte e armazenamento, assim como a manipulação das frutas podem levar a contaminação. Os dados de crescimento obtidos para Salmonella mostram que este patógeno pode sobreviver e se multiplicar tanto na polpa quanto na casca do caqui, nas duas variedades estudadas e mesmo a baixas temperaturas. / The worldwide consumption of fresh produce has increased in the last years, due to an increased concern among the population about health. However, the search for more healthful eating habits has also increasing the risk of acquiring a foodborne disease, as these products generally are consumed raw. Although any pathogen can be a potential problem in these produces, Salmonella spp. is of great relevance in public health. The potential contamination for this pathogen in fruits, is possible due to cross contamination and poor agricultural practices during harvest, handling and distribution. In low acid fruits, amongst which is persimmon, Salmonella spp can still have conditions to survive and to multiply. The persimmon is a fruit of great economic importance, with increasing demand for exportation, however, the import market has an increase demand for food safety. There are not in Brazil, information about the occurrence of Salmonella spp in persimmon, as well as, information regarding the behavior of this pathogen in the pulp and the rind of this fruit. Thus, the objectives of the present study had been: (1) to verify the incidence of Salmonella spp on the surface of persimmon, (2) to study the survival and multiplication of S. Enteritidis on the peel and in the pulp of this fruit stored at different temperatures of incubation. For this survey in 2005 and 2006 harvests, 77 samples and 80 samples of \'Fuyu\' and \'Rama Forte\' persimmon respectively collected in the retail in Campinas city - SP. Additionally in 2006, 134 samples of each \'Rama Forte\' and \'Fuyu\' persimmon were also collected in the CEAGESP, in São Paulo city. The analyses had been carried using the BAX® system (Dupont/Qualicon), that is based on the Polymerase Chain Reaction (PCR). The parameters of growth during the evaluation of the ability of growth of S. Enteritidis (lag phase duration, exponential growth rate and generation time) were obtained from experimental data. Salmonella spp were detected in five samples (0,9%) of those analysed. The growth data obtained for Salmonella indicated that this pathogen can survive and multiply on the peel as well as in the pulp in the two studied varieties and even at low temperatures.

Incidência de úlceras por pressão e fatores de risco em idosos institucionalizados / Ulcer incidence by pressure and risk factors in institutionalized elders

Souza, Diba Maria Sebba Tosta de 08 July 2005 (has links)
A ocorrência de úlceras por pressão (UP) é realidade em vários locais de assistência à saúde e caracterizam-se por serem lesões freqüentemente encontradas em pacientes graves hospitalizados ou em locais de institucionalização por longos períodos. O objetivo geral deste estudo foi: analisar a incidência de úlceras por pressão e os fatores de risco para o seu desenvolvimento em pessoas idosas residentes em Instituições de Longa Permanência (ILPI). Trata-se de estudo quantitativo de coorte, prospectivo. Inicialmente o projeto foi aprovado pelo Comitê de Ética em Pesquisa da Universidade do Vale do Sapucaí e aprovação dos responsáveis em quatro Instituições de Longa Permanência para os idosos (ILPI), em 3 cidades do Sul de Minas Gerais, que constituíram os locais para a coleta de dados. A amostra constou de 94 idosos que atenderam os seguintes requisitos: ter idade igual ou superior a 60 anos; apresentar escore = 18 (em aplicação da Escala de Braden) e aceitar participar do estudo. Os dados foram obtidos através de exame físico, entrevista e análise dos prontuários, pela pesquisadora além de 9 colaboradores, enfermeiros e alunos de graduação, previamente treinados. Os idosos, que se enquadraram nos critérios de inclusão, foram avaliados 3 vezes na semana, durante 90 dias consecutivos ou até que desenvolvessem UP ou tivessem alta, transferência ou óbito. Os dados obtidos foram submetidos a análises descritivas e inferencial através de teste Qui-Quadrado de Pearson, Exato de Fisher, Kolmogorov-Smirnov, t-Student, e o não paramétrico de Mann-Whitney. Os resultados mostraram incidência cumulativa global de 39,4% e taxa de incidência (ou incidência por densidade) de 0,57 UP por 100 paciente-dias. Verifica-se que 37 (77,08%) idosos desenvolveram úlcera única; as localizações preferenciais foram o maléolo (27,08%) e o ísquio (25,00%) e as UP em estágio I foram as mais freqüentes (66,67%). Quanto às características demográficas dos idosos, houve predomínio do sexo feminino (62,80%) e da raça branca (68,19%), com idade média de 79,06 ± 9,59. Clinicamente, apresentaram IMC médio de 20,93 ± 4,95, predominando as doenças urinárias (58,50%), uso de neurolépticos /psicotrópicos (52,10%), não tabagismo (80,90%). Úlcera prévia esteve presente em 28,70% dos idosos estudados. Tanto na 1ª como na segunda avaliação de risco, a sub escala mobilidade apresentou os maiores valores de alfa de a-Cronbach (0,6591 e 0,6631) mostrando-se a mais relevante para a avaliação do risco. As seguintes variáveis mostraram-se associadas à presença de UP, na análise univariada: sexo feminino (p= 0,012); uso de medicamentos neurolépticos /psicotrópicos (p=0,016); presença de úlcera prévia (p=0,041); sub escala umidade (p=0,021), na primeira avaliação e sub escalas nutrição (p=0,013), fricção e cisalhamento (p=0,036) e umidade (p=0,034), na última avaliação. Sexo feminino e presença de úlcera prévia foram confirmados como preditivos para o desenvolvimento de UP, segundo a regressão logística (r2=0,311), mostrando 3,46 e 2,76 vezes mais chances de desenvolverem UP comparativamente aos homens e aos idosos sem UP, respectivamente. Além desses resultados, os escores totais da Escala de Braden diferiram entre os grupos com e sem UP, entre a 1ª (p=0,030) e última avaliações (p=0,001), sendo sempre menores para os idosos com UP. Em conclusão, este estudo contribui não somente para a informação acerca da incidência de UP e os principais fatores de risco para o seu desenvolvimento, em idosos institucionalizados, escassa em nosso meio, como para a sistematização de métodos que possam ser reaplicados em outros centros e em investigações futuras / The occurrence of ulcers by pressure (UP) is a reality in many places of health assistance and they are characterized for being frequent lesions found in serious hospitalized patients or in institutionalization places for long periods. The general aim of this study was analyzing the incidence of ulcers by pressure and the risk factors for their development in elderly people living in Long Staying Institutions (LSI). It is a prospective, cohort quantitative study. At first, the project was approved by the Ethics Committee in Research of the Universidade do Vale do Sapucaí and approved by the people in charge of four Long Staying Institutions (LSI) for elderly people in three cities in the south of Minas Gerais State which served as the place for the data collect. 94 elders who attended the following profile formed the sample: age was equal or superior to 60 years old; to show a score = 18 (in applying the Braden scale) and to accept in taking part in the study. The data were acquired through a physical examination, interview and the handbook analysis by the researcher and other nine collaborators, nurses and graduation students, previously trained for that. The elderly, who fitted into the inclusion criteria, were assessed three times a week for 90 days, with no interruption, or until they developed an ulcer or until they were send out of the hospital, were transferred or died. The data acquired were submitted to descriptive and inferential analyses through the Pearson Qui-Square test, Fisher Exact, Kolmogorov-Smirnov, t-student and the non-parametric of Mann-Whitney. The results showed a global cumulative incidence of 39,4% and incidence rate (or density by incidence) of 0,57 UP by a 100 patients-day. It is possible to verify that 37 (77,08%) elders developed single ulcer; the preferential location were the malleolus (27,08%) and the ischium (25,00%) and the UP in first stage were the most frequent ones (66,67%). In relation to the demographic features of the elders, there was a preponderance of the female sex (62,80%) and the white race (68,19%), with an age average ranging from 79,06 ± 9,59. Clinically, they presented an average CMI ranging from 20,93 ± 4,95, with a predominance of urinary diseases (58,50%), use of neuroepileptics/psycothropics (52,10%), non smoking (80,90%). The previous ulcer was present in 28,70% of the elderly studied. In the first as well as in the second risk assessment, the sub-scale mobility presented the higher values of alpha of ? -Cronbach (0,6591 and 0,6631) showing itself as the most relevant for the risk assessment. The following variables showed themselves associated to the presence of UP, in a single varied analysis: female sex (p=0,012); use of neuroepileptics/psycothropics medicines (p=0,016%); presence of previous ulcer (p=0,041%); humidity sub-scale (p=0,021), in the first assessment and the nutrition sub-scales (p=0,013), rubbing and and shearing stress (p=0,036) and humidity (p=0,034), in the last assessment. Female sex and previous ulcer presence were confirmed as predictive for the development of UP, according to the logistic regression (r2=0,311), showing 3,46 and 2,76 times more chances of developing UP comparatively to men and elderly without UP, respectively. Besides these results, the total scores of the Braden Scale were different between the groups with and without UP, between the first (p=0,030) and the last assessment, being always the smallest ones for the elderly with UP. As we can conclude, this study contributes not only for the information about the incidence of the UP and the main risk factors for its development, in institutionalized elderly, very rare in our context, as for the systematization of methods that can be reapplied in other centers and in future investigations
