COVID-19 outcomes in people living with HIV: Peering through the waves

Objective: To evaluate clinical characteristics and outcomes of COVID-19 patients infected with HIV, and to compare with a paired sample without HIV infection. Methods: This is a substudy of a Brazilian multicentric cohort that comprised two periods (2020 and 2021). Data was obtained through the retrospective review of medical records. Primary outcomes were admission to the intensive care unit, invasive mechanical ventilation, and death. Patients with HIV and controls were matched for age, sex, number of comorbidities, and hospital of origin using the technique of propensity score matching (up to 4:1). They were compared using the Chi-Square or Fisher's Exact tests for categorical variables and the Wilcoxon for numerical variables. Results: Throughout the study, 17,101 COVID-19 patients were hospitalized, and 130 (0.76%) of those were infected with HIV. The median age was 54 (IQR: 43.0;64.0) years in 2020 and 53 (IQR: 46.0;63.5) years in 2021, with a predominance of females in both periods. People Living with HIV (PLHIV) and their controls showed similar prevalence for admission to the ICU and invasive mechanical ventilation requirement in the two periods, with no significant differences. In 2020, in-hospital mortality was higher in the PLHIV compared to the controls (27.9% vs. 17.7%; p = 0.049), but there was no difference in mortality between groups in 2021 (25.0% vs. 25.1%; p > 0.999). Conclusions: Our results reiterate that PLHIV were at higher risk of COVID-19 mortality in the early stages of the pandemic, however, this finding did not sustain in 2021, when the mortality rate is similar to the control group

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

Butang® response was assessed in 224 newborns who were given the vaccine in the VG region and 250 in the ALT one. Both groups were similar regarding gender, weight, timing interval between doses of the vaccine and maternal characteristics. When comparing Butang® immunogenicity, we verified that the proportion of babies who developed anti-HBs protecting titres after three vaccine doses in the VG region was of 97.8% (IC 95%: 94.8 99.3) with geometric mean titer (GMT) of 427.5 mUI/mL (IC 95%: 344.9 530.0), similar to those who were given in the ALT region (97.6%; IC 95%: 94.8 99.1; GMT: 572.0 mUI/mL; IC 95%: 471.1 694.6), which provides evidence that this place is appropriate for hepatitis B vaccination. Eleven newborns did not respond to Butang®, being six of them vaccinated in the VG region and five in the ALT. The most of them were male, one factor which seems to interfere with hepatitis B vaccine response. We verified an increasing proportion of local reactions and fever according to the number of doses given. In addition, after the third dose the proportion of induration (4.0 vs. 11.4) was higher among babies who were given the vaccine in the ALT region when compared to those who were given in the VG region (p < 0,05). No association was observed concerning maternal anti-HBs titres and newborn vaccine response. The evidences of this study showed that the VG region is a safe and immunogenic site to hepatitis B vaccine administration in newborns.Este estudo trata-se do primeiro ensaio clínico randomizado controlado, para avaliação da imunogenicidade e reatogenicidade da vacina Butang® em recém-nascidos a termo, que receberam a primeira dose da vacina nas primeiras doze horas de vida, comparando duas regiões de aplicação do imunógeno: ventro glútea (VG) e vasto lateral da coxa (VLC). A resposta à Butang® foi avaliada em 224 RN vacinados na região VG e 250 na VLC. Os dois grupos foram semelhantes quanto ao sexo, peso, intervalo de tempo entre as doses da vacina e características maternas. Ao comparar a imunogenicidade da Butang®, verificou-se que a proporção de crianças que desenvolveu títulos protetores de anti-HBs após a vacinação na região VG foi de 97,8% (IC 95%: 94,8-99,3) com média geométrica dos títulos (GMT) de anti-HBs de 427,5 mUI/mL (IC 95%: 344,9 530,0), sendo semelhante às vacinadas na região VLC (97,6%; IC 95%: 94,8 99,1; GMT: 572,0 mUI/mL; IC 95%: 471,1 694,6), evidenciando, portanto, esses locais como apropriados para a administração do imunógeno. Onze RN não responderam à Butang® com títulos protetores, sendo que cinco foram vacinados na região VG e seis na VLC. A maioria dessas crianças era do sexo masculino, um fator que parece interferir na resposta vacinal contra hepatite B. Em geral, observou-se uma proporção maior de reações locais e febre de acordo com o número de doses recebidas. Além disso, após a terceira dose da vacina, a proporção de enduração foi menor (4,0 vs. 11,4) em crianças vacinadas na região VG do que nas vacinadas na VLC (p < 0,05). Não foi observada qualquer associação entre títulos de anti-HBs maternos e resposta vacinal dos seus conceptos. As evidências deste estudo mostram que a região VG é um local seguro e imunogênico para a administração da vacina contra hepatite B em lactentes

Ensaio clínico controlado randomizado. Participaram do estudo 61 pessoas, 31 do grupo de intervenção (região VG) e 30 do grupo controle (região DG). O teste de qui-quadrado e Mann– Whitney foram utilizados para testar diferenças entre proporções e comparar tendências centrais entre os grupos, respectivamente. Valores de p ˂ 0,05 foram considerados estatisticamente significantes. Nos três momentos avaliados, a média do escore de dor foi maior quando a aplicação do fármaco ocorreu na região VG vs. DG. No primeiro e terceiro minuto a diferença foi estatisticamente significativa. Estes resultados ratificam a região VG como local alternativo com menor reação local para aplicação de injeções intramusculares.The objective of this study was to compare the pain level related to the administration of benzathine penicillin on the ventrogluteal (VG) and dorsogluteal (DG) region. A randomized controlled trial. Sixty-one people participated in the study, 31 on the intervention group (VG region), and 30 on the control (DG region). The Chi-Squared and Mann-Whitney tests were used to test differences of proportions and to compare central tendencies between groups, respectively. Values of p <0.05 were considered statistically significant. At the three assessed moments, the mean score of pain was higher when the application of the drug was on the VG region vs. DG. At the first and third minute, the difference was statistically significant. These results confirm the VG region as alternative place with less local reaction to apply intramuscular injections

Conceptions of parents of adolescent students about the sexuality of their children

Objective: to know the conceptions of parents of adolescent students about the sexuality of their children. Methods: it is a qualitative research modality Strategic Research, using focus groups guided by a semi structured instrument with 15 parents of adolescent students. The data were submitted to content analysis in which the following categories emerged: “Understanding aspects related to sexuality”; “Difficulties for dialogue”; “Facilities for dialogue”; and “The tasks of the family and the school to support the theme.” Results: parents had superficial knowledge and misconceptions on the subject. Great difficulty of dialogue between parents and children has been identified, justified by ignorance and timidity of parents and the lack of opening of the adolescent, still, there was recognition of family responsibility in this context. Conclusion: there is need for expansion of intersectoral work involving segments of the education, health and universities to support families with information about sexuality in the school context
