Abstract Objective COVID-19 is associated with an elevated risk of thromboembolism and excess mortality. Difficulties with best anticoagulation practices and their implementation motivated the current analysis of COVID-19 patients who developed Venous Thromboembolism (VTE). Method This is a post-hoc analysis of a COVID-19 cohort, described in an economic study already published. The authors analyzed a subset of patients with confirmed VTE. We described the characteristics of the cohort, such as demographics, clinical status, and laboratory results. We tested differences amid two subgroups of patients, those with VTE or not, with the competitive risk Fine and Gray model. Results Out of 3186 adult patients with COVID-19, 245 (7.7%) were diagnosed with VTE, 174 (5.4%) of them during admission to the hospital. Four (2.3% of these 174) did not receive prophylactic anticoagulation and 19 (11%) discontinued anticoagulation for at least 3 days, resulting in 170 analyzed. During the first week of hospitalization, the laboratory most altered results were C-reactive protein and D-dimer. Patients with VTE were more critical, had a higher mortality rate, worse SOFA score, and, on average, 50% longer hospital stay. Conclusion Proven VTE incidence in this severe COVID-19 cohort was 7.7%, despite 87% of them complying completely with VTE prophylaxis. The clinician must be aware of the diagnosis of VTE in COVID-19, even in patients receiving proper prophylaxis.

RESUMO. O tratamento antirretroviral tem aumentado significativamente a sobrevida de pacientes contaminados pelo HIV-1. Entretanto, com o aumento da sobrevida, observam-se frequentemente alterações cognitivas associadas ao HIV nessa população. As manifestações clínicas das alterações do HIV podem variar em decorrência de diversos aspectos, entre eles a via de transmissão do vírus. Diversos estudos têm apontado alterações neurológicas prematuras em pacientes contaminados por via vertical, enquanto a manifestação de danos cognitivos em adultos pode levar um tempo maior. Objetivo: O objetivo deste estudo foi verificar a prevalência das alterações cognitivas em pacientes com HIV via transmissão vertical após a era da terapia antirretroviral altamente ativa e o desempenho cognitivo desses pacientes comparado ao de um grupo de pacientes contaminados por via sexual. Métodos: Foram avaliados 48 pacientes, sendo 25 com transmissão vertical e 23 com transmissão sexual no período entre maio de 2013 e fevereiro de 2015, no Instituto de Infectologia Emílio Ribas. Foram aplicados testes neuropsicológicos para avaliar o desempenho cognitivo, escalas para avaliar sintomas de ansiedade e depressão e questionário sociodemográfico. Resultados: Os resultados demonstraram que a frequência de comprometimento cognitivo em pacientes contaminados via transmissão vertical foi maior do que naqueles contaminados via transmissão sexual. Conclusões: Essas descobertas sugerem que os efeitos deletérios do vírus HIV na formação do sistema nervoso central repercutem de forma mais acentuada do que em pacientes que o adquiriram após a vida adulta.

ABSTRACT. Antiretroviral treatment has significantly increased the survival of patients infected with HIV-1. However, with increased survival, cognitive changes associated with HIV are frequently observed in this population. The clinical manifestations of HIV changes can vary as a result of several aspects, including the virus transmission route. Several studies have pointed out premature neurological changes in vertically infected patients, while the manifestation of cognitive damage in adults may take a longer time. Objective: The aim of this study was to verify the prevalence of cognitive changes in patients with HIV via vertical transmission after the highly active antiretroviral therapy and the cognitive performance of these patients compared to a group of sexually infected patients. Methods: A total of 48 patients were evaluated, 25 with vertical transmission and 23 with sexual transmission, between May 2013 and February 2015 at the Institute of infectology Emilio Ribas. Neuropsychological tests were applied to assess cognitive performance, scales to assess symptoms of anxiety and depression, and sociodemographic questionnaire. Results: The results demonstrate that the frequency of cognitive impairment in vertically transmitted patients was higher than in sexually transmitted patients. Conclusions: These findings suggest that the deleterious effects of the HIV virus on the development of the central nervous system reverberate more strongly than in patients who acquire it after adulthood.

ABSTRACT Interferon-gamma (IFN-γ) plays a crucial role in viral infections by preventing viral replication and in the promotion of innate and adaptive immune responses. However, IFN-gamma can exert distinct effects in different persistent viral infections. The long-term overproduction of IFN-γ in retroviral infections, such as the human immunodeficiency virus (HIV), human T-lymphotropic virus type 1 (HTLV-1), and human endogenous retroviruses (HERVs), resulting in inflammation, may cause neuronal damage. This review is provocative about the role of IFN-γ during persistent retroviral infections and its relationship with the causation of some neurological disorders that are important for public health.

Abstract: En | Text: En | PDF: En

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

Abstract: En | Text: En | PDF: En

ABSTRACT Coronavirus disease 19 (COVID-19) is caused by SARS-Cov-2 and the manifestations of this infection range from an absence of symptoms all the way up to severe disease leading to death. To estimate the prevalence of past infection in a population, the most readily available method is the detection of antibodies against the virus. This study has investigated the prevalence of anti-SARS-CoV-2 antibodies in outpatients of the Hospital das Clinicas, in Sao Paulo city (Brazil), which is a large university hospital belonging to the public health system that cares for patients with complex diseases who need tertiary or quaternary medical care. Our serological inquiry was carried out for 6 weeks, with once-a-week blood sampling and included 439 patients from several outpatient services. Overall, 61 patients tested positive for anti-SARS-CoV-2 IgG (13.9%); 56.1 % of the patients live in Sao Paulo city, with the remaining living in other towns of the metropolitan area; 32.8% of the patients testing positive for IgG antibodies to SARS-CoV-2 were asymptomatic, 55.7% developed mild or moderate disease and 11.5% had to be hospitalized. The prevalence of SARS-CoV-2 positive serology was lower among patients who had received the seasonal influenza vaccine compared to the ones who did not. These findings may indicate that those individuals care more about health issues, and/or that they have a better access to health care and/or a better quality of health care service. The large proportion of patients who were unaware of having had contact with SARS-CoV-2 deserves attention, reflecting the scarcity of tests performed in the population.

RESUMO OBJETIVO Estimar a magnitude e identificar padrões de mudança na mortalidade por câncer de próstata no estado de São Paulo e nas 17 redes regionais de atenção à saúde, segundo grupos etários a partir dos 50 anos, no período de 2000 a 2015. MÉTODOS As taxas de mortalidade ajustadas por idade (por 100 mil homens) foram calculadas pelo método direto usando a população mundial de Segi como padrão. A análise de regressão Joinpoint foi utilizada para calcular as variações percentuais anuais médias (AAPC), com intervalo de confiança de 95% (IC95%), por rede regional e grupo etário (50–59, 60–69, 70–79 e 80 anos ou mais). RESULTADOS Para o estado de São Paulo, as taxas ajustadas de mortalidade foram de 15,2, 13,3 e 11,9/100 mil homens, respectivamente, nos períodos de 2000 a 2005, 2006 a 2010 e 2011 a 2015, com tendência de decréscimo significativo (AAPC = -2,10%; IC95% -2,42 – -1,79) a cada ano. Das 17 redes, 11 apresentaram reduções médias anuais significativas, que variaram entre -1,72% e -3,05%. A partir dos 50 anos, verificou-se redução mais acentuada nos grupos de 50 a 59 (AAPC = -2,33%; IC95% -3,04 – -1,62) e 60 a 69 anos (AAPC = -2,84%; IC95% -3,25 – -2,43). CONCLUSÕES Embora as reduções na mortalidade ainda sejam discretas, indicam progresso nas ações de controle do câncer de próstata. Ações de rastreamento e mudanças nas condutas terapêuticas nas últimas décadas podem estar modificando a incidência e a sobrevida, resultando em mudanças no perfil de mortalidade. Estudos mais detalhados serão úteis na compreensão dos fatores que levam às variações inter-regionais encontradas.

ABSTRACT OBJECTIVE To estimate the magnitude and identify patterns of change in prostate cancer mortality in the state of São Paulo and in the 17 regional health care networks, according to age groups from 50 years onwards, in the period between 2000 to 2015. METHODS Age-adjusted mortality rates (per 100,000 men) were calculated by the direct method using the Segi world population as standard. Joinpoint regression was used to calculate the average annual percent change (AAPC), with a confidence interval of 95% (95%CI), by regional network and age group (50–59, 60–69, 70–79 and 80 years or more). RESULTS For the state of São Paulo, age-adjusted mortality rates were 15.2, 13.3 and 11.9 per 100,000 men, respectively, in the periods between 2000 to 2005, 2006 to 2010 and 2011 to 2015, with a significant decrease trend (AAPC = -2.10%; 95%CI -2.42 – -1.79) each year. Among the 17 networks, 11 presented significant mean annual reductions, ranging from -1.72% to -3.05%. From the age of 50 onwards, there was a sharper reduction in the groups from 50 to 59 (AAPC = -2.33%; 95%CI -3.04 – -1.62) and 60 to 69 years (AAPC = -2.84%; 95%CI – 3.25 – -2.43). CONCLUSION Although reductions in mortality are still slight, they indicate progress in prostate cancer control actions. Screening actions and changes in therapeutic behaviors in recent decades may be modifying incidence and survival, resulting in changes in the mortality profile. More detailed studies will be useful in understanding the factors that lead to the interregional variations found.

ABSTRACT Objective: We evaluated the association between cognitive deficits and leukocyte telomere length (LTL) in HIV-1-infected individuals. Design: 73 HIV-1-infected patients undergoing neuropsychological evaluation and 91 healthy controls were included in this study. Fifteen HIV-1 positive patients did not have cognitive disorders whereas 26 had asymptomatic neurocognitive disorder (ANI), 13 presented mild to moderate neurocognitive disorder (MND), and 10 had HIV-associated dementia (HAD). Methods: DNA from the peripheral blood of HIV-1-infected patients was used for measurement of telomere length by real-time PCR. HIV-1 viral load was determined in blood. Results: LTL decreased with age in healthy controls (p=0.0001). Regardless of the HIV status, age-matched LTL from HIV patients, including those with ANI and MND, were shortened in comparison to the healthy control group (p=0.0073); however, no association was found among the HIV-1-infected individuals with cognitive deficits (p=0.01). In addition, no gender-related association with LTL was observed (p=0.80), smoking, physical exercise, and plasma viral load were not correlated to telomere length (p=0.66). Conclusions: We concluded that leukocyte telomere length may not be a marker of cellular senescence in individuals with HIV infection and neurocognitive disorders.

ResumoO estudo avaliou a prevalência de depressão pós-parto (DPP) e fatores associados em mulheres que deram à luz em dois hospitais da cidade de São Paulo: um público e outro privado. Foram aplicados questionários padronizados, a Escala de Depressão Pós-parto de Edimburgo (EDPE) e a Escala de Apoio Social de MOS (EAS) a 462 mulheres: 205, no hospital público e 257, no privado. Foram obtidos dados sociodemográficos, psicossociais, obstétricos e do recém-nascido (RN). Consideraram-se deprimidas mulheres com 12 ou mais pontos na EDPE, aplicada no 3º ou 4º mês após o parto. No hospital público, a prevalência de DPP foi de 26% e, no privado, de 9%. Características dos RN foram semelhantes nas duas amostras; idade, escolaridade, número de visitas de pré-natal e de cesarianas das mães foram maiores no hospital privado. Análise de regressão envolvendo características psicossociais das participantes revelou associação positiva de DPP com depressão anterior e com frequência de conflitos com o parceiro e relação negativa com anos de escolaridade e escore de apoio social.

AbstractThis study evaluated the prevalence of postpartum depression (PPD) and associated factors in women who gave birth at two hospitals in São Paulo City: one public and other private. It was applied standardized questionnaires, the Edinburgh Postnatal Depression Scale (EPDS), and the MOS Social Support Scale to 462 women: 205 in the public hospitals and 257, in the private one. Data collected included sociodemographic, psychosocial, obstetric and newborn (NB) characteristics. It was considered depressed those women with 12 or more points in EPDS, applied in the 3rd. or 4th. month after delivery. In the public hospital, the prevalence of PPD was 26% and in the private, 9%. Characteristics of infants were similar in both samples, Mothers' age, education level, number of prenatal visits and cesarean were higher in the private hospital. Regression analysis involving psychosocial characteristics of women showed a positive association of PPD with previous occurrence of depression and frequency of conflicts with partner and negative relationship with years of schooling, and social support scores.

CONTEXTO E OBJETIVO: O único tratamento eficaz para pacientes que têm reações graves após ferroada de Hymenoptera é a imunoterapia com veneno. O objetivo deste estudo foi rever a literatura para avaliar os efeitos da imunoterapia com veneno em pacientes com reações graves após ferroada de Hymenoptera. TIPO DE ESTUDO E LOCAL: Foram revisados na literatura mundial ensaios clínicos controlados e aleatórios. O manuscrito foi realizado na Disciplina de Alergia e Imunologia Clínica, Universidade de São Paulo (USP). MÉTODOS: Ensaios clínicos controlados e aleatórios envolvendo imunoterapia com veneno de Hymenoptera versus placebo ou apenas acompanhamento dos pacientes foram avaliados. Realizada imunoterapia específica, o risco de reações sistêmicas foi avaliado através de cálculo do "odds ratio" e intervalo de confiança de 95%. RESULTADOS: 2.273 resumos foram identificados na busca pelas palavras chave. Apenas quatro estudos foram incluídos nesta revisão. O teste qui-quadrado de heterogeneidade mostrou que dois estudos foram homogêneos e puderam ser incluídos na metanálise. Ao combinar os dois estudos, o "odds ratio" passou a ser significativo: 0.29 (0.10-0.87). Entretanto, ao analisar a gravidade das reações ocorridas após a imunoterapia, observou-se que os benefícios podem não ser tão relevantes, pois as reações foram, na grande maioria, ou mais leves ou semelhantes à reação original. CONCLUSÕES: A imunoterapia específica deve ser recomendada para adultos e crianças com reações moderadas a graves, porém não há necessidade de prescrevê-la para as crianças apenas com reações cutâneas, especialmente se a exposição é muito esporádica. No outro lado, a relação risco-benefício deve ser sempre avaliada em cada caso.

CONTEXT AND OBJECTIVE: The only effective treatment for patients who have severe reactions after Hymenoptera stings is venom immunotherapy. The aim of this study was to review the literature to assess the effects of venom immunotherapy among patients presenting severe reactions after Hymenoptera stings. DESIGN AND SETTING: Randomized controlled trials in the worldwide literature were reviewed. The manuscript was produced in the Discipline of Allergy and Clinical Immunology, Universidade de São Paulo (USP). METHODS: Randomized controlled trials involving venom immunotherapy versus placebo or only patient follow-up were evaluated. The risk of systemic reactions after specific immunotherapy was evaluated by calculating odds ratios (OR) and their 95% confidence intervals. RESULTS: 2,273 abstracts were identified by the keywords search. Only four studies were included in this review. The chi-square test for heterogeneity showed that two studies were homogeneous and could be included in a meta-analysis. By combining the two studies, the odds ratio became significant: 0.29 (0.10-0.87). However, analysis on the severity of the reactions after immunotherapy showed that the benefits may not be so significant because the reactions were mostly similar to or milder than the original reaction. CONCLUSIONS: Specific immunotherapy should be recommended for adults and children with moderate to severe reactions, but there is no need to prescribe it for children with skin reactions alone, especially if the exposure is very sporadic. On the other hand, the risk-benefit relation should always be assessed in each case.

OBJETIVO: A mortalidade por câncer iniciou declínio nos países desenvolvidos nos anos 90, mas seu comportamento nos países em desenvolvimento é menos conhecido. Estudo anterior abordando a mortalidade por câncer no Brasil mostrou queda na mortalidade pelo conjunto dos cânceres, mas a qualidade dos dados suscitou críticas quanto à validade dos resultados. As informações de mortalidade das capitais dos estados do Brasil são de melhor qualidade que aquelas para o país como um todo, possibilitando análise mais acurada das tendências. MÉTODOS: Os dados de mortalidade e população foram obtidos das bases de dados do Ministério da Saúde e do IBGE. Calcularam-se taxas ajustadas por idade e taxas específicas por idade, para ambos os sexos. Empregou-se regressão linear para avaliar a significância das mudanças de tendência. RESULTADOS: As taxas de mortalidade pelo conjunto dos cânceres declinaram, (-4,6% para os homens e -10,5% para as mulheres). O câncer de estômago mostrou queda de taxas nos dois sexos, assim como o câncer de pulmão entre os homens, enquanto as taxas do câncer de próstata aumentaram. No sexo feminino, â€œcâncer do útero não especificado" apresentou redução e o câncer de pulmão, aumento de taxas. O câncer de mama mostrou-se estável, e o câncer do colo do útero aumentou suas taxas ao final do período. CONCLUSÃO: Conforme já registrado em países desenvolvidos, a mortalidade pelo conjunto dos cânceres nas capitais de estados brasileiros mostrou tendência de queda entre 1980 e 2004, o que se deveu fundamentalmente ao declínio da mortalidade por câncer de estômago.

OBJECTIVE: Cancer mortality rates began to decline in developed countries in the 1990s, but their behavior in developing countries is less well-known. An earlier study on cancer mortality in Brazil showed a declining mortality trend for cancer as a whole. however the quality of data results raised some criticism t. The population of state capitals comprises about a quarter of the total Brazilian population and for these cities mortality data available have a better quality than for the entire country, enabling analyses of trends in cancer rates based on more accurate data. METHODS: Mortality and population data were collected from government databases (SIM/DATASUS and IBGE, respectively). Age-adjusted (world standard) and age-specific mortality rates were calculated for both genders . Linear regression was used to investigate changes in trends. RESULTS: For all cancers as a whole mortality rates declined throughout the study period for both men and women (-4.6% and -10.5%, respectively). For both genders , the cancer that decreased most was stomach cancer. Among men, lung cancer death rates presented a slight reduction, while prostate cancer rates increased. Among women, "uterus, site unspecified' presented a downward trend, while lung cancer rates increased. The trend for breast cancer remained stable, and cervix uterus rates showed a slight increase at the end of the period. CONCLUSION: As already seen in developed countries, all cancer mortality rates tended to decline in Brazilian state capitals over the period 1980-2004, a tendency largely due to a decline in stomach cancer death rates for both genders.

O câncer do colo do útero apresenta grande incidência em algumas cidades brasileiras e considerável mortalidade em países em desenvolvimento, não obstante a disponibilidade já antiga de teste de rastreamento. O presente estudo visou avaliar a tendência da mortalidade por câncer de colo do útero, de corpo do útero e por câncer do útero não especificado, no Município de São Paulo, entre 1980 e 1999, por meio do exame das taxas brutas, idade-específica e ajustadas por idade. Os resultados mostraram discreta redução da mortalidade por câncer do colo do útero, queda da mortalidade por câncer de útero não especificado e aumento da mortalidade por câncer do corpo do útero. Conclui-se que a queda da mortalidade por câncer do útero não especificado sinaliza uma melhora na precisão do diagnóstico clínico e na qualidade do preenchimento do atestado de óbito, e indica aumento de cobertura do teste de Papanicolaou.

Uterine cervical cancer shows a higher incidence in some Brazilian cities. It is a common cause of death in women from developing countries, despite the longstanding availability of an effective screening test, the Pap smear. This study aimed to evaluate the temporal trends of crude, age-adjusted, and age-specific mortality rates from cervical cancer, endometrial cancer, and cancer of the uterus not otherwise specified (NOS) in the city of São Paulo from 1980 to 1999. Results showed a slight reduction in cervical cancer rates, a decrease in NOS uterine cancer rates, and an increase in endometrial cancer mortality rates. The fall in mortality from NOS uterine cancer indicates an improvement in diagnostic accuracy and quality of information on death certificates and may point to an increase in coverage of cervical cancer screening using the Pap smear.
