ICU Admission, Invasive Mechanical Ventilation, and Mortality among Children and Adolescents Hospitalized for COVID-19 in a Private Healthcare System.

Aim: The COVID-19 pandemic devastated healthcare around the world. Data about the COVID-19 outcomes among young people are still scarce. We aim to identify factors associated with the composite outcome among children and adolescents hospitalized due to COVID-19. Methods: We performed a search in the database of a large Brazilian private healthcare system. Insured people aged 21 years or younger who were hospitalized due to COVID-19 from Feb/28th/2020 to Nov/1st/2021 were included. The primary endpoint was the composite outcome consisting of ICU admission, need for invasive mechanical ventilation, or death. Results: We evaluated 199 patients who had an index hospitalization due to COVID-19. The median monthly rate of index hospitalization was 2.7 (interquartile range [IQR], 1.6-3.9) per 100,000 clients aged 21 years or less. The median age of the patients was 4.5 years (IQR, 1.4-14.1). At the index hospitalization, the composite outcome rate was 26.6%. The composite outcome was associated with all the previous coexisting morbidities evaluated. The median follow-up was 249.0 days (IQR, 152.0-438.5). There were 27 readmissions (16 patients) within 30 days after the discharge. Conclusions: In conclusion, hospitalized children and adolescents had a composite outcome rate of 26.6% at the index hospitalization. Having previous chronic morbidity was associated with the composite.

Systematic review and meta-analysis of ivermectin for treatment of COVID-19: evidence beyond the hype.

BACKGROUND: The role of ivermectin in the treatment of COVID-19 is still under debate, yet the drug has been widely used in some parts of the world, as shown by impressive market data. The available body of evidence may have changed over the last months, as studies have been retracted and "standards of care" (SOC) used in control groups have changed with rapidly evolving knowledge on COVID-19. This review aims to summarize and critically appraise the evidence of randomized controlled trials (RCTs) of ivermectin, assessing clinical outcomes in COVID-19 patients. METHODS: RCTs evaluating the effects of ivermectin in adult patients with COVID-19 were searched through June 22, 2022, in four databases, L.OVE platform, clinical trial registries and pre-prints platforms. Primary endpoints included all-cause mortality and invasive ventilation requirement. Secondary endpoint was the occurrence of adverse events. Risk of bias was evaluated using the Cochrane Risk of Bias 2.0 tool. Meta-analysis included only studies which compared ivermectin to placebo or SOC. Random-effects were used to pool the risk ratios (RRs) of individual trials. The quality of evidence was evaluated using GRADE. The protocol was register in PROSPERO (CRD42021257471). RESULTS: Twenty-five RCTs fulfilled inclusion criteria (n = 6310). Of those, 14 compared ivermectin with placebo, in night ivermectin associated with SOC was compared to SOC and two studies compared ivermectin to an active comparator. Most RCTs had some concerns or high risk of bias, mostly due to lack of concealment of the randomization sequence and allocation, lack of blinding and high number of missing cases. Ivermectin did not show an effect in reducing mortality (RR = 0.76; 95%CI: 0.52-1.11) or mechanical ventilation (RR = 0.74; 95%CI: 0.48-1.16). This effect was consistent when comparing ivermectin vs. placebo, and ivermectin associated with SOC vs. SOC, as well as in sensitivity analysis. Additionally, there was very low quality of evidence regarding adverse effects (RR = 1.07; 95%CI: 0.84-1.35). CONCLUSIONS: The evidence suggests that ivermectin does not reduce mortality risk and the risk of mechanical ventilation requirement. Although we did not observe an increase in the risk of adverse effects, the evidence is very uncertain regarding this endpoint.

Access to private health insurance in the metropolitan region of Manaus, AM, Brazil, in 2015: a cross-sectional population-based study. / Acesso a planos de saúde na região metropolitana de Manaus em 2015: estudo transversal de base populacional.

OBJECTIVE: to analyze the frequency and factors associated with coverage by health insurance in the metropolitan region of Manaus, AM, Brazil. METHOD: a cross-sectional population-based study was conducted in 2015, with data collected through household interviews; prevalence ratios (PR) and confidence intervals (95%CI) were calculated using Poisson regression with robust variance adjusted for sex and age. RESULTS: we interviewed 4,001 individuals; 13% (95%CI - 12.0;14.1%) had health insurance; greater insurance coverage was observed among military personnel (PR=3.18 - 95%CI 1.64;6.15), private sector employees (PR=1.91 - 95%CI 1.46;2.52) and public sector employees (PR=1.75 - 95%CI 1.23;2.49); health insurance was lower among poorer people (PR=0.21 - 95%CI 0.13;0.33), and those with less schooling (PR=0.66 - 95%CI 0.46;0.99). CONCLUSION: frequency of health insurance was low and was associated with better purchasing power, schooling, and employment.

Artificial urinary sphincter for urinary incontinence after radical prostatectomy: a historical cohort from 2004 to 2015

ABSTRACT This study aimed to retrospectively evaluate a cohort of patients with prostate cancer and persistent urinary incontinence after radical prostatectomy. From January 2004 to December 2015, eighty-six individuals were identified to have received an AUS implant, provided by a private nonprofit HMO operating in Belo Horizonte, Brazil. On total, there were 91 AUS implants, with a median interval between radical prostatectomy and AUS implant of 3.6 years (IQR 1.9 to 5.5). The rate of AUS cumulative survival, after a median follow-up of 4.1 years (IQR 1.7-7.2 years), was 44% (n=40). The median survival of AUS implants was 2.9 years (IQR 0.5-7.9 years). Thirty-seven AUS implants (40.7%) resulted in grade III surgical complications. There were 5 deaths at 2.1, 4.7, 5.7, 5.7 and 6.5 years of follow-up, but none due to causes directly associated to the AUS implant. Persistent severe incontinence was documented in 14 (15.3%) additional patients. From the 51 AUS implants which resulted in grade III surgical complications or persistent severe incontinence, 24 (47.1%) underwent surgical revisions. Explantation of the sphincter or its components was observed in 6 cases (25.0%). Mechanical failure, described as fluid loss and/or inability to recycle the AUS device, was observed in 4 devices (16.7%). In conclusion, although AUS implants are recommended as the gold-standard treatment of severe urinary incontinence after prostatectomy, the observed high rates of malfunction and grade III adverse events are a matter of concern warranting further assessment on the safety and efficacy of these devices.

[The profile of patients undergoing bariatric surgery in the Brazilian Unified National Health System: a systematic review]. / Perfil de pacientes submetidos à cirurgia bariátrica, assistidos pelo Sistema Único de Saúde do Brasil: revisão sistemática.

Nearly one million Brazilians were morbidly obese in 2013. Bariatric surgery is an option for sustained weight loss, and the Brazilian Unified National Health System (SUS) had provided 50,000 such procedures as of 2014. The SUS database does not provide anthropometric and comorbidity data on these patients, so the aim of the current study was to perform a systematic review to assess the profile of SUS patients that underwent bariatric surgery from 1998 to 2014. The MEDLINE, LILACS, SciELO, and Scopus databases were searched, and the methodological quality of the included articles was assessed. Of the 1,591 identified studies, 39 were selected, 95% of which were observational. Patients had a mean age of 41.4 years and mean body mass index of 48.6kg/m2; 21% were males, 61% hypertensive, 22% diabetics, and 31% presented sleep apnea. When compared to international study samples, SUS patients showed similar a anthropometric profile and comorbidities but higher prevalence of hypertension. The studies' low methodological quality suggests caution in interpreting the results.

Em 2013, quase um milhão de brasileiros eram obesos graves. A cirurgia bariátrica é uma alternativa para a perda de peso sustentada. Até 2014 foram realizadas quase 50 mil cirurgias pelo Sistema Único de Saúde (SUS) do Brasil, mas dados antropométricos e de comorbidades destes pacientes são pouco conhecidos. O objetivo do estudo foi realizar uma revisão sistemática para conhecer o perfil do paciente submetido à cirurgia bariátrica pelo SUS até 2014. Foram consultadas as bases MEDLINE, LILACS, SciELO e Scopus. A qualidade metodológica dos artigos incluídos foi avaliada por escores de Carson e Newcastle-Ottawa. Foram identificados 1.591 estudos e selecionados 39, sendo 95% observacionais. Em média, os pacientes têm 41,4 anos, índice de massa corporal 48,6kg/m2, 21% são homens, 61% hipertensos, 22% diabéticos e 31% têm apneia do sono. Comparado com pacientes incluídos em estudos internacionais, o paciente SUS apresenta perfil antropométrico e de comorbidades semelhante, exceto pela maior prevalência de hipertensão. A baixa qualidade metodológica dos estudos sugere precaução na interpretação dos resultados.

Ten-years of bariatric surgery in Brazil: in-hospital mortality rates for patients assisted by universal health system or a health maintenance organization / Dez anos de cirurgia bariátrica no Brasil: mortalidade intra-hopitalar em pacientes atendidos pelo sistema único de saúde ou por operadora da saúde suplementar

BACKGROUND: Bariatric surgery is an option for sustained weight loss for the morbidly obese patient. In Brazil coexists the Unified Health System (SUS) with universal coverage and from which depend 150 million Brazilians and supplemental health security, predominantly private, with 50 million beneficiaries. AIM: To compare access, in-hospital mortality, length of stay and costs for patients undergoing bariatric surgery, assisted in one or another system. METHODS: Data from DATASUS and IBGE were used for SUS patients' and database from one health plan of southeastern Brazil for the health insurance patients. RESULTS: Between 2001 and 2010 there were 24,342 and 4,356 surgeries performed in SUS and in the health insurance company, respectively. The coverage rates for surgeries performed in 2010 were 5.3 and 91/100.000 individuals in SUS and health insurance respectively. The rate of in-hospital mortality in SUS, considering the entire country, was 0.55 %, 0.44 % considering SUS Southeast, and 0.30 % for the health insurance. The costs of surgery in the SUS and in the health insurance trend to equalization over the years. CONCLUSION: Despite differences in access and characteristics that may compromise the outcome of bariatric surgery, patients treated at the Southeast SUS had similar rate of in-hospital mortality compared to the health insurance patients. .

RACIONAL: A cirurgia bariátrica é uma opção de perda de peso sustentada para o indivíduo obeso mórbido.

[ELSA-Brasil strategies for outcome identification, investigation and ascertainment]. / Estratégias de identifi cação, investigação e classifi cação de desfechos incidentes no ELSA-Brasil.

OBJECTIVE: The article describes the strategies adopted by the Brazilian Longitudinal Study for Adult Health (ELSA-Brasil) for participation and retention of subjects. This is key to ensure internal validity of longitudinal studies, and to identify, investigate, and ascertain outcomes of interest. METHODS: The follow-up strategies include annual telephone contacts with new assessments and interviews every three to four years this approach aims to identify transient outcomes (reversible or not), permanent outcomes as well as complications related to the progression of major diseases--cardiovascular diseases and diabetes--to be studied. RESULTS: Telephone interviews are designed to monitor subjects' health status and to identify potential health-related events such as hospital admissions, medical visits or pre-selected medical procedures. Subjects are also encouraged to report to the ELSA-Brasil team any new health-related events. When a potential event is identified, a thorough investigation is carried out to collect relevant information about that event from medical records. All data are blinded and reviewed and analyzed by a medical expert committee. Incident outcome ascertainment follows well-established international criteria to ensure data comparability and avoid misclassification. In addition to these strategies, the occurrence of health-related events is also investigated through linkage of secondary databases, such as national mortality and hospital admission databases. CONCLUSIONS: Accurate identification of outcomes will allow to estimating their incidence in the study cohort and to investigate the effect of the exposures studied in the ELSA-Brasil at baseline and at its subsequent waves.

Long-term mortality of patients submitted to Roux-en-Y gastric bypass in Public Health System: high prevalence of alcoholic cirrhosis and suicides.

BACKGROUND: Bariatric surgery is a valuable therapeutic option to severe obesity. Many researches have assessed the procedure efficiency on weight reduction, improvement in comorbidities and reduction of mortality. However, studies of late mortality and its causes are still necessary, mainly in the Brazilian population. AIM: To assess late mortality, discriminating causes of death and its association with pre-operative characteristics in a series of patients submitted to bariatric surgery. METHODS: Data analyses of 248 patients submitted to Roux-en-Y gastric bypass through Public Health System, from one up to 12 years of follow-up. The analyzed variables were: gender, age by the time of the surgery, pre-operative body mass index, comorbidities and smoking. The information about mortality was obtained through the Mortality Information System. The deaths were categorized according to International Classification of Diseases 10 and statistics analysis was done through the software STATA TM 9.2. RESULTS: There were nine deaths, five of them were female. The mean age of the patients who died was 48.3 ± 8.4 years and the pre-operative body mass index was 56.0 ± 7.4 kg/m². The causes of death were: alcoholic cirrhosis (n=2), suicide (n=2), infectious causes (n=2), respiratory insufficiency (n=1), agranulocytosis (n=1) and unknown causes (n=1). None of the deaths was directly related to the surgery and there was no association of the pre-operative characteristics in mortality. CONCLUSION: There was not any association between late mortality and pre-operative characteristics. The high frequency of suicide and alcoholic cirrhosis mortality indicates the strict follow-up concerns, with appropriate psychological support to the patients.

Mortalidade no pós-operatório tardio da derivação gástrica em pacientes do Sistema Único de Saúde: elevada frequência de cirrose alcoólica e suicídios / Long-term mortality of patients submitted to Roux-en-Y gastric bypass in Public Health System: high prevalence of alcoholic cirrhosis and suicides

RACIONAL: A cirurgia bariátrica é uma opção terapêutica valiosa para tratamento de casos graves de obesidade. Sua utilização em larga escala motivou a realização de diversas pesquisas que comprovaram a eficiência do procedimento na redução do peso corporal, melhora das comorbidades e redução da mortalidade em curto e médio prazo. Entretanto, são necessários mais estudos a respeito da mortalidade de médio e longo prazo e suas causas, principalmente na população brasileira. OBJETIVO: Avaliar a mortalidade após período mínimo de um ano da operação bariátrica discriminando as causas de óbito e sua relação com características pré-operatórias. MÉTODOS: Foram analisados os dados de 248 pacientes do Sistema Único de Saúde, com seguimento entre um e 12 anos, submetidos à derivação gástrica em Y-de-Roux. As variáveis analisadas foram: sexo, idade na operação, índice de massa corporal pré-operatório, presença de comorbidades e tabagismo. As informações sobre mortalidade foram obtidas através do Sistema de Informações sobre Mortalidade. Os óbitos foram categorizados segundo o Código Internacional de Doenças 10 e a análise estatística feita através do programa STATA TM 9.2. RESULTADOS: Ocorreram nove óbitos tardios, sendo cinco de mulheres. A média de idade dos pacientes que faleceram foi 48,3±8,4 anos e o índice de massa corporal pré-operatório foi 56,0±7,4 kg/m². As causas de óbito foram cirrose alcoólica (n=2), suicídios (n=2), causas infecciosas (n=2), insuficiência respiratória (n=1), agranulocitose (n=1) e causa desconhecida (n=1). Nenhum óbito teve relação direta com o procedimento cirúrgico e não houve influência das características pré-operatórias avaliadas na mortalidade. CONCLUSÃO: Não houve relação entre a mortalidade e as características pré-operatórias. A alta frequência de mortalidade por suicídio e por complicações do alcoolismo indica a necessidade de seguimento clínico mais rigoroso, envolvendo adequado apoio psicológico aos pacientes.

Does intravascular ultrasound provide clinical benefits for percutaneous coronary intervention with bare-metal stent implantation? A meta-analysis of randomized controlled trials.

BACKGROUND: The role of intravascular ultrasound (IVUS) in percutaneous coronary interventions (PCI) is still controversial despite several previously published meta-analyses. A meta-analysis to evaluate the controversial role of IVUS-guided PCI with bare-metal stenting was performed and a previous published meta-analysis was re-evaluated in order to clarify the discrepancy between results of these studies. METHODS: A systematic review was performed by an electronic search of the PubMed, Embase and Web of Knowledge databases and by a manual search of reference lists for randomized controlled trials published until April 2011, with clinical outcomes and, at least, six months of clinical follow-up. A meta-analysis based on the intention to treat was performed with the selected studies. RESULTS: Five studies and 1,754 patients were included. There were no differences in death (OR = 1.86; 95% CI = 0.88-3.95; p = 0.10), non-fatal myocardial infarction (OR = 0.65; 95% CI = 0.27-1.58; p = 0.35) and major adverse cardiac events (OR = 0.74; 95% CI = 0.49-1.13; p = 0.16). An analysis of the previous published meta-analysis strongly suggested the presence of publication bias. CONCLUSIONS: There is no evidence to recommend routine IVUS-guided PCI with bare-metal stent implantation. This may be explained by the paucity and heterogeneity of the studies published so far.

Costs and usage of healthcare services before and after open bariatric surgery.

CONTEXT AND OBJECTIVE: Morbidly obese individuals are major consumers of healthcare services, with high associated costs. Bariatric surgery is an alternative for improving these individuals' comorbidities. There are no studies comparing costs before and after bariatric surgery in Brazil. The aim here was to analyze results relating to healthcare usage and direct costs among morbidly obese patients undergoing bariatric surgery. DESIGN AND SETTING: Historical cohort study on patients receiving healthcare through a private health plan in Belo Horizonte, Minas Gerais. METHODS: All healthcare services and their associated costs were included in the analysis: hospitalization, hospital stay, elective outpatient consultations, emergency service usage and examinations. The analyses were treated as total when including the whole years before and after surgery, or partial when excluding the three-month periods adjacent to the operation. RESULTS: For 382 obese patients who underwent open bariatric operations, there were 53 hospitalizations one year before and 95 one year after surgery (P = 0.013). Gastrointestinal complications were the main indications for post-procedure hospitalizations. The partial average cost almost doubled after the operation (US$ 391.96 versus US$ 678.31). In subgroup analysis, the costs from patients with gastrointestinal complications were almost four times greater after bariatric surgery. Even in the subgroup without complications, the partial average cost remained significantly higher. CONCLUSION: Although bariatric surgery is the only path towards sustained weight loss for morbidly obese patients, the direct costs over the first year after the procedure are greater. Further studies, with longer follow-up, might elucidate whether long-term reversal of this trend would occur.

CONTEXTO E OBJETIVO: Indivíduos obesos mórbidos são grandes consumidores de serviços de saúde, com altos custos associados. A cirurgia bariátrica é uma alternativa para melhorar suas comorbidades. Não existem estudos comparando custos antes e após a cirurgia bariátrica no Brasil. O objetivo deste estudo foi analisar os resultados assistenciais e gastos diretos de pacientes obesos mórbidos submetidos à cirurgia bariátrica. TIPO DE ESTUDO E LOCAL: Coorte histórica de pacientes assistidos por um plano de saúde na cidade de Belo Horizonte, Minas Gerais. MÉTODOS: Foram incluídos na análise todos os serviços de saúde e seus custos associados: hospitalizações, permanência hospitalar, consultas eletivas e de emergência e exames. A análise foi tratada como total quando incluía todo o ano anterior e posterior à cirurgia, e parcial quando excluía os trimestres adjacentes à cirurgia. RESULTADOS: Para 382 pacientes obesos operados, houve 53 internações um ano antes e 95 um ano após a cirurgia (P = 0,013). As principais indicações para internação pós-procedimento foram complicações relacionadas ao trato gastrointestinal. O custo parcial médio quase dobrou no período pós-operatório (US$ 391,96 versus US$ 678,31). Em análise de subgrupo, pacientes com complicações do trato gastrointestinal apresentaram custos quase quatro vezes maiores no período pós-bariátrica, e mesmo no subgrupo sem estas complicações, o custo parcial médio permaneceu significativamente maior. CONCLUSÃO: Embora a cirurgia bariátrica seja o único caminho para perda de peso sustentada nos pacientes obesos mórbidos, os custos diretos até um ano pós-procedimento são maiores. Novos estudos, com maior tempo de acompanhamento, poderão verificar se essa tendência se reverte no longo prazo.

Mortality and hospital stay after bariatric surgery in 2,167 patients: influence of the surgeon expertise.

BACKGROUND: Postoperative mortality is a rare event after bariatric surgery. The main goal of this study was to calculate the 30-day mortality rate postbariatric "open" surgery and the length of hospital stay of patients assisted by a health maintenance organization in Brazil. We also investigate their association with sex, age, BMI, preexisting comorbidities, and volume of procedures performed by surgeons. METHODS: A total of 2,167 patients who underwent RYGB between 01/2004 and 12/2007 were analyzed. The deaths and hospital stay were identified in the healthcare transactional database and the morbidity data in the preoperative medical audit records. Factors contributing to adverse outcomes were determined by multiple logistic regression analysis. RESULTS: The overall mortality rate was 0.64%, with a decreasing trend over the years. The median hospital stay was 3.1 days. In the multivariate analysis, both mortality and longer hospital stay were positively and significantly associated with age > 50 years, BMI > 50 kg/m(2), and surgeon volume of less than 20 bariatric surgeries/year. Presence of hypertension also increased the risk of longer hospital stay. Multivariate analysis showed that the 30-day mortality was six times higher in patients operated by professionals who performed less surgeries/year and longer hospital stay, four times more frequent. CONCLUSIONS: The 30-day mortality post-RYGB is similar to the rates found in developed countries and much lower than the rates found for patients assisted by the public health system in Brazil. In addition to age and clinical factors, the results suggest that mortality and longer hospital stay are strong and inversely related to surgeon's experience.
