Adenovirus 36 Coinfection in People Living with HIV and its Impact on Lipohypertrophy.

BACKGROUND: Previous studies have implicated human adenovirus 36 (Adv36) as a potential contributor to overweight and obesity. People living with HIV have an altered body composition compared to healthy individuals. There is still no evidence to confirm the relationship of Adv36 as one of the causes of lipohypertrophy. The main objective of this study was to verify the viral Adv36 infection as a factor associated with the presence of lipohypertrophy in HIV-infected individuals. METHODS: A case-control study on people with HIV treated at a specialized public health service in southern Brazil. Subjects underwent interviews, diagnostic tests, and anthropometry to determine lipodystrophy and its classification. Demographic and clinical data were examined to investigate the presence of Adv36. The cases were participants with lipohypertrophy, and the controls were eutrophic participants. RESULTS: 101 participants were included (38 cases and 63 controls), and the frequency of Adv36 infection was 10.9%. There was a statistically significant association between lipohypertrophy and the female sex (p < 0.001), and a trend for the presence of Adv36 (p = 0.059) and lipohypertrophy. After adjustment for confounders, Adv36 has not considered an independent risk factor for lipohypertrophy. Lower levels of glucose were associated with Adv36 infection. CONCLUSION: There was a significant association between lipohypertrophy and the female sex, and no association with lipohypertrophy and Adv36, perhaps due to the small sample size.

Impact of topical airway anesthesia on immediate postoperative cough/bucking: a systematic review and meta-analysis

Abstract Background Postoperative cough may occur after tracheal intubation, but it is indistinct which drug is best at diminishing these events. Additionally, airway reflexes are commonly accompanied by severe hemodynamics responses during emergence. Objectives To evaluate the role of topical airway anesthesia on immediate post-extubation cough/bucking and extubation time. Methods Randomized clinical trials from MEDLINE, EMBASE, CENTRAL, and LILACS published until December 23, 2020 were included. Our primary outcome was postoperative cough/bucking incidence which was compared between local anesthetics and controls. Extubation times were likewise considered. Predisposition appraisal and subgroup, affectability investigations were likewise performed. Results The pooled analysis found a 45% reduction in cough incidence after treatment with topical airway local anesthetic (RR = 0.55; 95% CI: 0.42 to 0.72; p< 0.001). The number needed to treat (NNT) was 4.61. The intervention showed no differences in reduction of the extubation time (mean difference = -0.07; 95% CI: -0.14 to 0.28; p= 0.49). Conclusion Topical airway anesthesia demonstrated better than placebo or no medication in reducing immediate post-extubation cough/bucking. Further studies could have this objective to combine the different ways to perform better outcomes for patients.

Post-vaccination incidence and side effects of COVID-19 in a cohort of Brazilian healthcare professionals: an internet-based survey.

OBJECTIVE: So far, at least 18 different severe acute respiratory syndrome coronavirus-2 vaccines have been approved. Until October 2022, 12.8 billion doses had been administered all over the world. Vaccination of high-risk groups and healthcare professionals was initially prioritized. This cross-sectional survey aimed to investigate the occurrence of vaccine side effects, as well as the incidence of COVID-19 among vaccinated healthcare professionals. METHODS: A survey was structured and shared with healthcare professionals using a digital platform to collect data between May and June 2021. RESULTS: This study included 6,115 participants. The most prevalent age group was 30-39 years (31.3%), 67.3% were female and 73.2% accounted for physicians, and nearly half worked in frontline care for COVID-19. Approximately, two-thirds of them were vaccinated with CoronaVac, and about 60% reported at least one side effect following the vaccination. Nevertheless, minor reactions were more frequent, such as pain at site of injection, fatigue, and headache. Our data could be used to inform people on the likelihood of side effects of COVID-19 vaccines, particularly CoronaVac, since this is the largest study about vaccine reactions using this vaccine, to our best knowledge. CONCLUSION: The incidence of side effects in Brazilian healthcare professionals was 60%, and the most common side effects included local swelling/pain, fatigue/tiredness, fever, headache, and limb pain.

Ultrasound-guided erector spinae plane block for open inguinal hernia repair: a randomized controlled trial.

BACKGROUND AND OBJECTIVES: Inguinal hernia repair is associated with significant postoperative pain. We assessed the analgesia efficacy of unilateral Erector Spinae Plane block (ESP) performed under ultrasound guidance in patients submitted to open unilateral inguinal hernia repair, comparing ESP to spinal anesthesia administered with or without opioid. METHODS: Forty-five patients with ages ranging from 27 to 83 years were randomly allocated into three groups: control group receiving spinal anesthesia (n = 14), ESP group receiving ESP block combined with spinal anesthesia (n = 16), and spinal morphine group receiving spinal anesthesia with morphine 1 mcg.kg-1 as adjuvant drug (n = 15). ESP was performed at the T8 level using 0.5% ropivacaine, 20 mL. We assessed the pain intensity in the initial 24 hours after surgery using the Visual Analogue Scale - VAS and rescue opioid requirement. RESULTS: The ESP group showed four times higher consumption of rescue opioids than the spinal morphine group, or 26.7% vs. 6.2%, respectively (RR = 4.01; 95% CI: 0.82 to 19.42; p = 0.048). The spinal morphine group showed higher incidence of adverse effects than the ESP group, 37.5% vs. 6.7%, respectively (p = 0.039). There were no statistically significant differences among groups for the mean values of VAS score at 24 hours after surgery (p = 0.304). CONCLUSION: At the doses used in this study, the ESP block was an ineffective technique for providing postoperative analgesia in unilateral open inguinal hernioplasty and was associated with higher consumption of rescue opioids when compared to spinal anesthesia with or without opioid.

Perfil dos pacientes com hiperferritinemia em acompanhamento ambulatorial em um serviço no sul do Brasil / Profile of patients with hyperferritinemia in ambulatorial follow-up in southern Brazil

O achado de hiperferritinemia é comum na prática clínica. Além de representar os estoques de ferro no organismo, a ferritina se mostra como proteína de fase inflamatória, podendo elevar-se em comorbidades inflamatórias agudas ou crônicas e se associar com a chamada síndrome plurimetabólica. Objetivo: Avaliar as características clínicas de pacientes com hiperferritinemia em acompanhamento ambulatorial no período de janeiro de 2013 a novembro de 2016. Métodos: Estudo observacional transversal, desenvolvido em um serviço de Hematologia na cidade de Tubarão, Santa Catarina. Coletaram-se dados de 136 pacientes com o diagnóstico de hiperferritinemia através de prontuários digitais. Foram realizadas análises descritivas e associações com os testes qui-quadrado e t Student, quando apropriado. Resultados: Houve um predomínio do sexo masculino (83,50%) com idade média de 56,62 anos, a média de ferritina de 693,45mcg/L e de ferro sérico 121,52mcg/dL, sendo as causas secundárias de hiperferritinemia as predominantes. Ao se estratificar os valores de ferritina constatou-se que os pacientes com ferritina >1000mcg/L tiveram um risco 50% maior de possuir alterações ao ultrassom, 70% maior prevalência de HDL<40 e 40% maior prevalência de hipertrigliceridemia. Os pacientes com ferritina >400mcg/L tiveram duas vezes maior chance de apresentar resistência à insulina. Conclusão: As principais causas de hiperferritinemia foram secundárias a doenças crônicas metabólicas

Hyperferritinemia is common in the clinical practice. In aside from representing the stocks of iron in the organism, ferritin is also a inflammatory phase protein, witch can be elevated in chronic or acute inflammatory comorbidities and be associated with plurimetabolic syndrome. This study aims the evaluation of the clinical characteristics of ambulatory patients with hyperferritinemia between January-2013 and November-2016. Methods: It is a cross-sectional, descriptive study, developed in the hematology center of the medical specialities clinic in Tubarão ­ Santa Catarina. Data from 136 patients have been collected and then transferred to an Excel spreadsheet, imported to Epiiinfo 7 and the expressed into absolute and relative numbers, graphics and figures. Results: It was found a predominance of males (83,50%) with a mean age of 56,62 years, a mean ferritin level of 693,45mcg/L and seric iron of 121,52mcg/dL being the secondary causes of hyperferritinemia the most predominant. When stratified the ferritin levels, it was verified that patients with a ferritin >1000mcg/L had 50% more risk of having ultrasound alterations, 70% more prevalence of HDL<40 and 40% more prevalence of having hypertriglyceridemia. Patients with a ferrintin >400mcg/L had twice as many chances of having insulin resistance. Conclusion: The main causes of hyperferritinemia were secondary to chronic metabolic diseases

Risk rates of workplace accidents in Brazil: effect of the Accidental Prevention Factor (APF)? / Taxas de risco de acidentes de trabalho no Brasil: efeito do Fator Acidentário de Prevenção (FAP)?

Historically, the conflict of interests between employers and workers obliged the State to assume the role of regulating this relationship, instituting laws and overseeing the application of health and safety standards at work. The Accident Prevention Factor (FAP) is one of these guidelines. This article aims to analyze the correlations between the FAP and the risk rate for occupational accidents in Brazil in the period between 2006 and 2016. Ecological study, which analyzed the occupational accidents, registered in the Brazilian Social Security database in the period between 2006 and 2016. The analysis included the calculation of accident risk rates according to the Brazilian regions, divisions of the CNAE, reason/situation, ICD-10 chapters, sex and age. The comparison between results from the two periods was performed using the average risk rates from the two periods using Student t test, Spearman correlation and beta value. Basically, all rate series analyzed had a strong downward trend in the FAP period, contrary to what occurred in the immediately previous period.

A ocorrência de acidentes e de doenças relacionadas ao trabalho são expressões concretas da exposição dos trabalhadores aos riscos presentes no ambiente laboral. Historicamente o conflito de interesses entre empregadores e trabalhadores obrigou o Estado a assumir a função de regulação desta relação, instituindo leis e fiscalizando a aplicação das normas de saúde e segurança no trabalho. O Fator Acidentário de Prevenção (FAP) é uma dessas estratégias. O objetivo deste artigo é analisar a correlação entre as taxas de risco de acidentes de trabalho no Brasil antes (2006-2009) e depois (2010-2016) da vigência do FAP. Estudo ecológico com análise temporal de séries de taxas de acidentes de trabalho registrados nas bases de dados da Previdência Social no período 2006 e 2016. A análise incluiu o cálculo das taxas de risco de acidentes segundo grandes regiões brasileiras, divisões do CNAE, motivo/situação, capítulos do CID-10, sexo e idade. A comparação entre os resultados dos dois períodos foi realizada utilizando-se as taxas de risco médias com a aplicação do teste t de Student e da correlação de Spearman. Basicamente todas as séries de taxas analisadas obtiveram forte tendência de redução no período de vigência do FAP, ao contrário do que ocorreu no período imediatamente anterior.

Melatonin can be, more effective than N-acetylcysteine, protecting acute lung injury induced by intestinal ischemia-reperfusion in rat model.

OBJECTIVES: The current study compared the impact of pretreatment with melatonin and N-acetylcysteine (NAC) on the prevention of rat lung damage following intestinal ischemia-reperfusion (iIR). METHODS: Twenty-eight Wistar rats were subjected to intestinal ischemia induced by a 60 min occlusion of the superior mesenteric artery, followed by reperfusion for 120 min. Animals were divided into the following groups (n=7 per group): sham, only abdominal incision; SS+iIR, pretreated with saline solution and iIR; NAC+iIR, pretreated with NAC (20 mg/kg) and iIR; MEL+iIR, pretreated with melatonin (20 mg/kg) and iIR. Oxidative stress and inflammatory mediators were measured and histological analyses were performed in the lung tissues. RESULTS: Data showed a reduction in malondialdehyde (MDA), myeloperoxidase (MPO), and TNF-alpha in the animals pretreated with NAC or MEL when compared to those treated with SS+iIR (p<0.05). An increase in superoxide dismutase (SOD) levels in the NAC- and MEL-pretreated animals as compared to the SS+iIR group (34±8 U/g of tissue; p<0.05) was also observed. TNF-α levels were lower in the MEL+iIR group (91±5 pg/mL) than in the NAC+iIR group (101±6 pg/mL). Histological analysis demonstrated a higher lung lesion score in the SS+iIR group than in the pretreated groups. CONCLUSION: Both agents individually provided tissue protective effect against intestinal IR-induced lung injury, but melatonin was more effective in ameliorating the parameters analyzed in this study.

Comparison between subarachnoid morphine and femoral nerve block for analgesia after knee ligament reconstruction: a randomized clinical trial / Comparação entre morfina subaracnoidea e bloqueio do nervo femoral para analgesia após reconstrução ligamentar de joelho: estudo clínico randomizado

Abstract Background and objectives There are no consensus of the ideal technique to provide analgesia in knee ligament reconstructions. The aim of this study was to compare the intensity of postoperative pain in these patients under different modalities of analgesia. Method Randomized and controlled clinical trial of patients undergoing reconstruction of the Anterior Cruciate Ligament (ACL) with flexor tendons between December 2013 and 2014. All patients underwent spinal anesthesia and rescue analgesia with tramadol. The groups C, M, R0,375 and R0,25 was compared with only the previously described technique, subarachnoid morphine (100░µg), or Femoral Nerve Block (BNF) with 25░mL of 0.375% ropivacaine and 0.25%, respectively. Pain intensity at 6, 12 and 24░hours, age, sex, rescue analgesia, adverse reactions and satisfaction were evaluated. Results Among the 83 eligible patients, a predominance of males (85.7%) was observed, between 28 and 31 years. The group C requested more opioid (27.3%) than the other groups, without significance when compared. There were no significant differences in pain intensity at 6, 12 and 24░hours. There was a higher incidence of urinary retention in the M group (23.8%) than in the R0,375 (0%) and prolonged quadriceps motor block in the R0,375 group (30%) than in the M and C groups (0%), with statistical significance (p░<░0.05). Conclusion There was no difference in the intensity of postoperative pain in patients submitted to ACL reconstruction with flexor tendons under the analgesic modalities evaluated, despite the predominance of urinary retention in the M group and motor block in the R0,375 group.

[Comparison between erector spinal plane block and epidural block techniques for postoperative analgesia in open cholecystectomies: a randomized clinical trial]. / Comparação entre as técnicas de bloqueio do plano do músculo eretor da espinha e bloqueio epidural para analgesia pós­operatória em colecistectomias abertas: um ensaio clínico randomizado.

INTRODUCTION AND OBJECTIVES: Blockade of the Erector Spinal Muscle (ESP block) is a relatively new block, initially described for chronic thoracic pain analgesia, but it has already been described for anesthesia and analgesia in thoracic surgical procedures and, more recently, for high abdominal surgeries. The aim of the study was to compare two techniques, ESP Block and Epidural block with morphine and local anesthetic for postoperative analgesia of open cholecystectomy surgeries. METHODS: Controlled single-blind randomized clinical trial with 31 patients (ESP block, n = 15; Epidural, n = 16), of both genders, ages between 27 and 77 years. The ESP block was performed at the T8 level with injection of 20 mL of 0.5% ropivacaine bilaterally. The epidural block was performed at the T8-T9 space with 20 mL of 0.5% ropivacaine and 1 mg of morphine. RESULTS: The ESP block group presented higher mean Numeric Pain Scale (NPS) values for pain in the up to 2 hour (p = 0.001) and in the 24 hour (p = 0.001) assessments. The ESP block group had a three-fold increased risk (43.7% vs. 13.3%) of rescue opioid use in the 24 postoperative hours when compared to the epidural group (RR = 3.72, 95% CI: 0.91 to 15.31, p = 0.046). CONCLUSION: ESP block did not prove to be an effective technique for postoperative analgesia of open cholecystectomy, at the doses performed in this study, having required more use of rescue opioid, and without differences in NPS. More comprehensive studies are required to assess the efficacy of ESP block for the visceral and abdominal somatic component, considering the specific blockade level.

Methods: Controlled single-blind randomized clinical trial with 31 patients (ESP Block, n = 15; Epidural, n = 16), of both genders, ages between 27 and 77 years. The ESP block was performed at the T8 level with injection of 20 mL of 0.5% ropivacaine bilaterally. The epidural block was performed at the T8-T9 space with 20 mL of 0.5% ropivacaine and 1 mg of morphine. Results: The ESP Block group presented higher mean ​​Numeric Pain Scale (NPS) values for pain in the up to 2 hour (p = 0.001) and in the 24 hour (p = 0.001) assessments. The ESP Block group had a three-fold increased risk (43.7% vs. 13.3%) of rescue opioid use in the 24 postoperative hours when compared to the epidural group (RR = 3.72, 95% CI: 0.91 to 15.31, p = 0.046). Conclusion: ESP Block did not prove to be an effective technique for postoperative analgesia of open cholecystectomy, at the doses performed in this study, having required more use of rescue opioid, and without differences in NPS. More comprehensive studies are required to assess the efficacy of ESP block for the visceral and abdominal somatic component, considering the specific blockade level.

Resumo Justificativa e objetivo: O Bloqueio do Plano do Músculo Eretor da Espinha (ESP block) é um bloqueio relativamente novo, inicialmente descrito para analgesia de dor torácica crônica, porém já descrito para anestesia e analgesia em procedimentos cirúrgicos torácicos e, mais recentemente, para cirurgias abdominais altas. O estudo objetivou comparar as técnicas de bloqueio ESP e bloqueio Epidural com morfina e anestésico local para analgesia pós-operatória de cirurgias de colecistectomia aberta. Método: Estudo clínico randomizado controlado, unicego com 31 pacientes (ESP block, n = 15; Epidural, n = 16), de ambos os sexos, idades entre 27 e 77 anos. O ESP block foi realizado no nível de T8 com injeção de 20 mL de ropivacaína 0,5% bilateral. O bloqueio Epidural foi realizado no espaço T8-T9 com 20 mL de ropivacaína 0,5% e 1 mg de morfina. Resultados: O grupo ESP block apresentou valores médios de dor pela Escala Visual Numérica (EVN) maiores nas avaliações até 2 horas (p= 0,001) e em 24 horas (p= 0,001). O grupo ESP block apresentou um risco três vezes maior - 43,7%vs.13,3% - de uso de opioide de resgate em 24 horas pós-operatórias do que o grupo epidural (RR = 3,72; 95% IC 0,91 a 15,31; p= 0,046). Conclusão: Nas doses realizadas nesse estudo, o ESP block não se mostrou uma técnica efetiva para analgesia pós-operatória de colecistectomia aberta, com mais uso de opioide de resgate e sem diferenças na escala visual numérica de dor. Necessita-se de estudos mais abrangentes avaliando a eficácia do ESP block para o componente visceral e somático abdominal, considerando o nível do bloqueio específico.

Effects of sertraline in the prevention of low blood pressure in patients undergoing hemodialysis / Efeitos da sertralina na prevenção de hipotensão arterial em pacientes submetidos à hemodiálise

Abstract Introduction: Intradialytic hypotension (IDH) is a major complication of hemodialysis, with a prevalence of about 25% during hemodialysis sessions, causing increased morbidity and mortality. Objective: To study the effects of sertraline to prevent IDH in hemodialysis patients. Methods: This was a double-blind, crossover clinical trial comparing the use of sertraline versus placebo to reduce intradialytic hypotension. Results: Sixteen patients completed the two phases of the study during a 12-week period. The IDH prevalence was 32%. A comparison between intradialytic interventions, intradialytic symptoms, and IDH episodes revealed no statistical difference in the reduction of IDH episodes (p = 0.207) between the two intervention groups. However, the risk of IDH interventions was 60% higher in the placebo group compared to the sertraline group, and the risk of IDH symptoms was 40% higher in the placebo group compared to the sertraline group. Survival analysis using Kaplan-Meier estimator supported the results of this study. Sertraline presented a number needed to treat (NNT) of 16.3 patients to prevent an episode from IDH intervention and 14.2 patients to prevent an episode from intradialytic symptoms. Conclusion: This study suggests that the use of sertraline may be beneficial to reduce the number of symptoms and ID interventions, although there was no statistically significant difference in the blood pressure levels.

Resumo Introdução: A hipotensão intradialítica (HID) é uma das principais complicações da hemodiálise, com uma prevalência de cerca de 25% durante as sessões de hemodiálise, causando aumento da morbimortalidade. Objetivo: Estudar os efeitos da sertralina na prevenção da HID em pacientes em hemodiálise. Métodos: Este foi um ensaio clínico duplo-cego, cruzado, comparando o uso de sertralina versus placebo para reduzir a hipotensão intradialítica. Resultados: Dezesseis pacientes completaram as duas fases do estudo durante um período de 12 semanas. A prevalência de HID foi de 32%. Uma comparação entre intervenções intradialíticas, sintomas intradialíticos (ID) e episódios de HID não revelou diferença estatística na redução dos episódios de HID (p = 0,207) entre os dois grupos de intervenção. No entanto, o risco de intervenções para HID foi 60% maior no grupo placebo em comparação com o grupo Sertralina, e o risco de sintomas ID foi 40% maior no grupo placebo em comparação com o grupo Sertralina. A análise de sobrevida utilizando o estimador de Kaplan-Meier corroborou os resultados deste estudo. A sertralina apresentou um número necessário para tratar (NNT) de 16,3 pacientes para prevenir um episódio de intervenção de HID e 14,2 pacientes para prevenir um episódio de sintomas intradialíticos. Conclusão: Este estudo sugere que o uso de sertralina pode ser benéfico para reduzir o número de sintomas e intervenções de HID, embora não tenha havido diferença estatisticamente significante nos níveis pressóricos.
