Clinical and epidemiological characteristics of children with sars-cov-2 infection admitted to a peruvian hospitalRodríguez-Portilla, Ricardo, Llaque-Quiroz, Patricia, Guerra-Ríos, Claudia, Cieza-Yamunaqué, Liliana Paola, Coila-Paricahua, Edgar Juan, Baique-Sánchez, Pedro Michael, Pinedo-Torres, Isabel 01 April 2021 (has links)
We carried out an observational, retrospective and descriptive study in order to identify the clinical and epidemiological characteristics of children with SARS-CoV-2 infection admitted to a Peruvian national referral hospital. We included patients from one month old to fourteen years old hospitalized between March and August 2020. A total of 125 patients with SARS-CoV-2 infection were admitted, 18.4% (n = 23) had critical illness and 16.8% (n = 21) had multisystem inflammatory syndrome (MIS-C). The absence of comorbidities and previous history of epidemiological contact were more frequent in patients with MIS-C. Patients in critical condition and patients with MIS-C had lower lymphocyte and platelet counts, and higher C-reactive protein, ferritin and D-dimer values than patients who did not have said conditions. Six (4.8%) out of 125 children died, as well as 3 (13%) children from the group of patients in critical condition. None of the children with MIS-C died. / Revisión por pares

Blood Type Effect on COVID-19 Infection And Tooth MovementLerman, Avigael, 0000-0003-1721-4294 January 2022 (has links)
Introduction: The objective of this study was to explore the influence of ABO blood type on COVID-19 infection rate. Discovered relationships may uncover whether genetic makeup may affect treatments and such information could be related to orthodontic tooth movements.
Methods: The PubMed database was searched using the terms: ABO Blood Group System; Blood-Group System, ABO; System, ABO Blood-Group; H Blood Group System; H Blood Group; Blood Group, H; ABH Blood Group; Blood Group, ABH; Blood Group H Type 1 Antigen; ABO Factors; Factors, ABO. Also included, were studies of ABO blood type and COVID infection or outcomes. Opinion pieces, animal studies, in-vitro studies, studies using blood other than ABO, and pre-2000 papers were excluded, as were studies that were not published in or translated to English. Of the included studies, the references were manually screened to identify additional qualified studies. Two independent reviewers reviewed the initial batch of reports to select the appropriate publications. To resolve conflicts, they met to discuss for a consensus. Studies were appraised by the Joanna Briggs Institute appraisal index. For the meta-analysis, studies which used odds ratio in their statistical analysis and COVID-19 infection as an outcome were included. Outcomes were analyzed using Forest Plots.
Results: Overall, this systematic review included 39 studies. 19 studies were cohort (2 prospective and 17 retrospective), 16 retrospective case control, and 4 were systematic reviews or meta-analysis. 31 studies reported a relationship between ABO blood type and COVID infection rates and 5 studies found no relationship. For the meta-analysis, 13 studies were included and analyzed. The estimated frequency of COVID-19 infection in terms of ABO blood groups and the overall effect size between blood groups was calculated with 95% confidence interval. The effect size of COVID-19 infection for blood group O versus the other blood groups was estimated as 0.174 (95% CI, o.o86-0.261) p<0.001. The effect size of COVID-19 infection for blood group A versus non-A was estimated as -0.174 (95% CI, -o.248- -0.100) p<0.001. The effect size of COVID-19 infection for blood group B versus non-B was estimated as -0.010 (95% CI, -0.107-0.086) p=0.831. The effect size of COVID-19 infection for blood group AB versus non-AB was estimated as -0.140 (95% CI, -o.344-0.064) p=0.179.
Conclusion: This meta-analysis indicates individuals with type O blood may be less susceptible to COVID-19 infection while those with type A blood may be more susceptible. Numerous studies, however, were not methodologically strong, as they had small sample size or suffered selection bias. Furthermore, no randomized controlled trials to determine causal relationships were found. Clearly this is understandable, given the speed with which the studies needed to be published. Despite such limitation, these findings have important implications for orthodontics because it may indicate that those with variants of Type A blood are more prone to inflammation, as orthodontic tooth movement is facilitated by the inflammatory responses of periodontal tissues. / Oral Biology

Construction of the Social Distance Scale and the Relationship Between Trait Empathy and Social DistancingPrachthauser, Michaela 01 January 2021 (has links)
This paper describes the development of a brief self-report screening measure of adherence to social distancing and self-protective behaviors in pandemic situations. It provides initial statistical evaluations of correlations between social distancing behaviors and two trait measures (social desirability and trait empathy). Items measures were designed to quantify behaviors recommended by the CDC as primary strategies to prevent and reduce the spread of the COVID-19 infection. An item pool of 29 questions was generated with the aim of estimating the frequency of specific behaviors and were written to avoid confounding the description of behavioral actions with evaluative judgements. Responses were collected from 401 young adults using an anonymous online survey. An Exploratory Factor Analysis was conducted with the purpose of item reduction and subscale development. A 14-item Social Distance Scale (SDS) emerged, consisting of 4-subscales: Isolation from Community (IC), Work from Home (WH), Family Contact (FC), and Protective Behaviors (PB). The initial psychometric evaluation of the scales indicated adequate internal consistency and test-retest reliability. The Social Distance Scale is a promising new instrument which may be applied at the population or individual level. It may be used in conjunction with COVID-19 testing to measure interactions between social distancing factors and transmission. In addition, a reliable screening measure has utility for health service providers to assess patient risk and to provide education/counseling.
A secondary purpose of this research was to examine the relationship between trait empathy and social distancing. A MANCOVA was performed using the four subscales of the SDS v.1 with Empathy Group and Gender Group as fixed factors and the Socially Desirable Response Set (SDRS-5) as a covariate. The SDRS-5 was found to be a significant covariate for both the IC and PB subscales of the SDS v.1 , where higher levels of socially desirable responding lead to higher scores on IC and PB. It was hypothesized that participants high in self-reported trait empathy would demonstrate higher levels of social distancing. Indeed it was found that a significant main effect for Empathy Group emerged, where Empathy Group was significantly related to IC, WH, and PB. In line with expectations, participants in the High Empathy Group scored higher on these three dimensions of social distancing than those in the Low Empathy Group. A significant main effect for Gender Group was obtained for PB. Women were found to be significantly more likely to engage in protective behaviors such as hand washing, mask wearing, and maintaining 6 feet of distance than men.

Ramipril Reduces Acylcarnitines and Distinctly Increases Angiotensin-Converting Enzyme 2 Expression in Lungs of RatsKosacka, Joanna, Berger, Claudia, Ceglarek, Uta, Hoffmann, Anne, Blüher, Matthias, Klöting, Nora 12 June 2023 (has links)
The angiotensin-converting enzyme 2 (ACE2) receptor has been identified as the entry
receptor for the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that is abundantly
expressed in many organs. With respect to the role of circulating ACE2 and its receptor expression
in the pathogenesis of the SARS-CoV-2 infection, it is still debated whether diseases such as hypertension or pharmacotherapies, including ACE inhibitors and angiotensin receptor blockers that
affect ACE2 receptor expression, may modulate the severity and outcome of the coronavirus disease
2019 (COVID-19). We therefore tested the hypothesis that treatment with the ACE inhibitor Ramipril
affects organ-specific ACE2 receptor mRNA and protein expression as well as the serum metabolome
in BioBreeding (BB) rats. Twelve male BioBreeding rats were randomly divided into a Ramipril
(10 mg/kg body weight) treatment group or a control group (N = 12; n = 6 per group) over a
period of seven days. Ramipril treatment resulted in the reduction of acylcarnitines (C3–C6) out
of 64 metabolites. Among the different organs studied, only in the lungs did Ramipril treatment
significantly increase both Ace2 mRNA and ACE2 receptor membrane protein levels. Increased ACE2
receptor lung expression after Ramipril treatment was not associated with differences in ACE2 serum
concentrations between experimental groups. Our data provide experimental in vivo evidence that
the ACE inhibitor Ramipril selectively increases pulmonary ACE2 receptor mRNA and protein levels
and reduces acylcarnitines.

Efecto de la pronación consciente en la saturación de oxígeno en pacientes hospitalizados por COVID-19 / Effect of conscious pronation on oxygen saturation in patients hospitalized for COVID-19Chambi, Liliana, Azañero-Haro, Johan, Piscoya, Tatiana, Quiñones- Laveriano, Dante M., Soto, Alonso 10 December 2021 (has links)
Objetivo: determinar el efecto de la pronación consciente en la saturación de oxígeno (SaO2) en pacientes hospitalizados por COVID-19.
Métodos: estudio de corte transversal analítico. La población estuvo conformada por los pacientes hospitalizados en uno de los pabellones por COVID-19 en el Hospital Nacional Hipólito Unanue durante el periodo junio a agosto del 2020. Se realizó un muestreo por conveniencia de tipo consecutivo de todos los pacientes comprendidos en el periodo de estudio. Se incluyó a pacientes hospitalizados mayores de 18 años, con el diagnóstico de neumonía por COVID-19. Fueron excluidos aquellos con algún grado de encefalopatía, post operados, gestantes, pacientes con inestabilidad hemodinámica. Se comparó la media de saturación arterial de oxígeno (SaO2) basal con la obtenida luego de una y dos horas de pronación. Asimismo, se evaluaron los factores asociados al cambio en la saturación. Resultados: de los 198 pacientes hospitalizados incluidos en el estudio, 144 (72.7%) fueron varones. El 31,8% eran mayores de 65 años y 30.3% menores de 49 años. La hipertensión arterial estaba presente en el 62,6%, siendo la comorbilidad más común seguida de la diabetes mellitus y la obesidad. La media de la SaO2 antes de la pronación fue de 89,4±0,24, incrementándose significativamente (p<0,001) a la hora posterior a la pronación a 95,6±0,30. A las dos horas, la media de SaO2 se incrementó a 96,7±0,30 (p < 0,001). En el análisis multivariado, el mayor recuento de linfocitos y plaquetas se asociaron en forma significativa a una mejor respuesta a la pronación, mientras que el antecedente de tuberculosis y los niveles de urea se asociaron a una menor respuesta. Conclusión: la pronación consciente se asocia a mejoras significativas en la SaO2 luego de una y dos horas de realizada la intervención. Esta intervención debe ser incluida en los protocolos de atención hospitalaria en el paciente con neumonía grave asociada a COVID-19.
