Vaccine effectiveness in preventing deaths in people with severe acute respiratory syndrome due to COVID-19 in Blumenau, Brazil, 2021.

OBJECTIVE: to analyze the vaccine effectiveness in preventing deaths attributed to severe acute respiratory syndrome due to COVID-19 (SARS/COVID-19) in adults and the elderly, in Blumenau, state of Santa Catarina, Brazil, 2021.this was a population-based study conducted among individuals aged 20 years and older hospitalized with SARS/COVID-19; each death due to SARS/COVID-19 was considered a "case", and every survivor was considered a "control"; the association between vaccination status and the outcome of "death" was estimated using logistic regression, and vaccine effectiveness was estimated as (1-OR)*100.The study included 1,756 cases of SARS/COVID-19 (59.2% male, mean age of 56 years, 50.4% with elementary education, 68.4% with comorbidities and 39.1% in intensive care), of whom 398 died (cases) and 1,358 survived (controls); vaccine effectiveness was 74% and 85% (20-59 years old) and 72% and 75% (≥ 60 years old), respectively, for those who were partially vaccinated and fully vaccinated. CONCLUSION: vaccines proved to be effective in reducing case fatality ratio due to SARS/COVID-19 in individuals ≥ 20 years old.

Nevirapine toxicity in a cohort of HIV-1-infected pregnant women.

OBJECTIVE: The purpose of this study was to complete an evaluation of nevirapine (NVP) toxicity in a cohort of HIV+ pregnant women. STUDY DESIGN: This was a retrospective study of 611 women followed from January 1996 to December 2003. All women who used NVP for > 7 days were included. Multivariate logistic regression was used to test independent association of CD4 and hepatitis C virus (HCV) infection related to the outcome of toxic effects of NVP. RESULTS: One hundred ninety-seven women were exposed to NVP for > 7 days, and toxicity occurred in 11 (5.6%), leading to drug discontinuation in 7 patients. One case of Stevens-Johnson syndrome occurred. No serious liver toxicity occurred except for 1 grade 4 cholestasis. Median CD4 was 344 in women without toxicities and 298 in women with toxicities. HCV was the only significant factor associated to toxicity by logistic regression (odds ratio [OR] 15.61, P = .001). CONCLUSION: NVP toxicities occurred in a very small fraction of patients and were not associated with fatalities.

Vertical transmission of HIV in Rio de Janeiro, Brazil.

A cohort of 297 HIV-infected pregnant women was followed from January 1996 to December 2001. The overall transmission rate was 3.57% and remained constant over time. Low birth-weight was independently associated with a higher risk of vertical transmission (P=0.0072), whereas a longer duration of antiretroviral drugs during pregnancy was independently associated with a lower risk of transmission (P=0.0084). Further decreases in transmission should be obtained by initiating prophylaxis earlier in pregnancy.

Evaluation of liquid biphasic Granada medium and instant liquid biphasic Granada medium for group B streptococcus detection.

INTRODUCTION: Group B streptococci (GBS) are transmitted from the mother to the newborn. Prevention of neonatal infection is achieved by intrapartum prophylaxis given to mothers colonized with GBS at 35 to 37 weeks of pregnancy. MATERIALS AND METHODS: Liquid biphasic Granada medium (LB) and instant liquid biphasic Granada medium (ILB) were evaluated for GBS detection. Vaginal swabs obtained from 300 women were inoculated onto LB or ILB, or onto Todd-Hewitt broth and analyzed with the ATB system (comparison method). RESULTS: Prevalence of GBS was 20% (61/300). LB and Todd-Hewitt with ATB detected GBS in 20% of women, and ILB in 19% of women. No growth was observed at four hours in any of the media studied. At 10 h and 14 h, identification of GBS was possible in 43/300 (14%) and 53/300 (18%) of ILB cultures, respectively, and in 32/300 (11%) and 46/300 (15%) of LB cultures. CONCLUSION: All the media used are suitable for GBS detection. The majority of GBS were identified in ILB and LB cultures at 10 h and 14 h.

Profilaxia medicamentosa da trombose venosa profunda em pacientes submetidos à cirurgia do trauma em um hospital universitário / Drug prophylaxis of deep venous thrombosis in patients submitted to trauma surgery in a university hospital

CONTEXTO: Anualmente, milhões de pessoas são vítimas de trauma no mundo. Além de suas consequências sociais e econômicas, muitos dos pacientes necessitam de tratamento cirúrgico, gerando, portanto, maiores riscos à vida. O tromboembolismo venoso, consequência da trombose venosa profunda, é uma importante causa de morbimortalidade em pós-operatórios e pode ser evitado com profilaxia adequada. OBJETIVO: Avaliar a utilização da profilaxia medicamentosa para trombose venosa profunda em pacientes submetidos à cirurgia do trauma de emergência, em um hospital-escola. MÉTODOS: Estudo transversal analítico, com 153 pacientes internados no Hospital Universitário Cajuru, em Curitiba, no Paraná, durante dois meses. Foram analisados prospectivamente prontuários de pacientes que necessitaram de cirurgia devido a trauma. O estudo incluiu pacientes classificados como alto e médio risco para trombose venosa profunda e avaliou-se a realização, ou não, da profilaxia medicamentosa. A análise estatística foi feita de forma descritiva. RESULTADOS: Dos 153 pacientes incluídos no estudo, 99 (64,7%) foram classificados como alto risco para trombose venosa e 54 (35,3%) como médio, sendo que 144 (94%) não receberam profilaxia medicamentosa. Dos nove (6%) pacientes que receberam profilaxia medicamentosa, um foi estratificado como médio risco e os outros oito de alto risco. Dos pacientes que receberam profilaxia, em apenas quatro a orientação foi adequada. CONCLUSÕES: A profilaxia para trombose venosa não é realizada de maneira rotineira nos pacientes de médio e alto risco para trombose venosa profunda que são submetidos à cirurgia do trauma e, quando realizada, muitas vezes é inadequada.

BACKGROUND: Annually, millions of people are victims of trauma around the world. Besides the social and economic consequences caused by it, many of these patients need surgical treatment, thus generating greater risk to life. Venous thromboembolism, a consequence of deep vein thrombosis, represents a major cause of the morbidity and mortality in postoperative state, and it could be avoided with adequate prophylaxis. OBJECTIVE: To evaluate the use of chemoprophylaxis for deep vein thrombosis, in patients undergoing emergency trauma surgery in a teaching hospital. METHODS: A cross-sectional analytic study was conducted with 153 patients admitted to Cajuru University Hospital, in Curitiba, Paraná, in a two-month period. Records of patients who required surgery due to trauma were prospectively analyzed. The study included those classified as high and medium risk for deep vein thrombosis. Then, it was identified whether or not the drug prophylaxis was used. A statistical analysis was descriptively performed. RESULTS: Of the 153 patients included, 99 (64.7%) were classified as high risk for deep vein thrombosis and 54 (35.3%) as medium risk. Of the total, 144 (94%) did not receive prophylaxis and nine (6%) did. On those who received prophylaxis, only four patients received the adequate. CONCLUSIONS: Prophylaxis of venous thrombosis disease is not performed routinely in patients of medium and high risk of developing deep vein thrombosis, who underwent trauma surgery. And, when performed, it is often inappropriate.
