RESUMO

Parkinson's disease (PD) is the second most common neurodegenerative disorder. The primary pathological features of PD include the presence of α-synuclein aggregates and Lewy bodies, mitochondrial dysfunction, oxidative stress, and neuroinflammation. Recently, omega-3 fatty acids (ω-3 PUFAs) have been under investigation as a preventive and/or therapeutic strategy for PD, primarily owing to their antioxidant and anti-inflammatory properties. Therefore, the objective of this study was to conduct a systematic review of the literature, focusing on studies that assessed the effects of ω-3 PUFAs in rodent models mimicking human PD. The search was performed using the terms "Parkinson's disease," "fish oil," "omega 3," "docosahexaenoic acid," and "eicosapentaenoic acid" across databases PUBMED, Web of Science, Science Direct, Scielo, and Google Scholar. Following analysis based on predefined inclusion and exclusion criteria, 39 studies were included. Considering behavioral parameters, pathological markers of the disease, quantification of ω-3 PUFAs in the brain, as well as anti-inflammatory, antioxidant, and anti-apoptotic effects, it can be observed that ω-3 PUFAs exhibit a potential neuroprotective effect in PD. In summary, this systematic review presents significant scientific evidence regarding the effects and mechanisms underlying the neuroprotective properties of ω-3 PUFAs, offering valuable insights for the development of future clinical investigations.

RESUMO

INTRODUCTION: burns represent a pivotal component of trauma in Brazil, accounting for 2 million incidents and 2,500 deaths annually. Self-intentional burns are associated with a worse prognosis, larger burned surface area, higher infection rates, and death. The lack of studies on the issue of self-immolation raises epidemiological questions regarding Brazilian victims. This study aimed to investigate the profile of burn events associated with self-injurious behavior among Brazilian victims. METHODS: this systematic review was performed according to PRISMA 2020 guidelines and evaluated the correlation between self-injurious behavior as a cause of burns in Brazilian victims and its epidemiological implications in the last 20 years (2003-2023). The MeSH terms "Burns", "Self-Injurious Behavior", "Epidemiology" and "Brazil" were queried in the PubMed/MEDLINE, SciELO, and Cochrane Library databases, and, after selection by inclusion/exclusion criteria, the most relevant studies were critically analyzed. RESULTS: From 1,077 pre-selected studies, 92 were potentially eligible, resulting in 7 manuscripts incorporated in this review. From 3,510 burned victims assembled in the pool of selected studies, 311 cases displayed self-injurious behavior. Burned patients who attempted to burn their lives have a higher risk of death (p<0.05; RR=5.1 [3.2-8.1]) and larger burned surface area (p<0.05; MD=19.2 [10-28.2]), compared to accidental cases. Moreover, the female gender was at a higher risk of attempting self-immolation (p<0.05; RR=4.01 [2.9-5.5]). CONCLUSION: our results show that self-inflicted burn cases were associated with a larger burned surface area and a higher risk of death, and the female gender was identified as a relevant risk factor in Brazil.

RESUMO

BACKGROUND: Some maternal characteristics are related to alcohol intake during pregnancy, which irreversibly compromises the maternal-fetal binomial integrity. OBJECTIVES: To identify the frequency, impact, and factors associated with alcohol consumption during pregnancy. DESIGN AND SETTING: A cross-sectional study was performed at the Hospital Materno Infantil Presidente Vargas (HMIPV) in Porto Alegre/RS between March and December 2016. METHODS: A structured questionnaire was administered along with a medical records review. They refer to the maternal sociodemographic and gestational status, alcohol consumption patterns, and characteristics of the fetus/newborn. In the statistical analysis, P values < 0.05 were considered significant. RESULTS: The frequency of alcohol intake was 37.3%; this was characterized by the consumption of fermented beverages (89.3%), especially during the first trimester (79.6%). Risky consumption (high and/or early) occurred for 30.2% of participants. Risk factors associated with maternal alcohol consumption during pregnancy were tobacco use (P < 0.001) and abortion attempt (P = 0.023). Living with a partner (P = 0.002) and planning pregnancy (P = 0.009) were protective factors. Risky consumption was related to all of the aforementioned variables as well as threatened abortion (P = 0.023). CONCLUSIONS: Alcohol intake during pregnancy is common and affects nearly one-third of pregnant women. Knowledge of the population at risk and protective factors is essential for the development of campaigns that seek to reduce consumption and, therefore, its consequences for the mother and fetus.

RESUMO

INTRODUCTION: Venous thromboembolism is widely recognized as a life-threatening complication in trauma, yet renal vein thrombosis (RVT) following trauma is particularly rare. PRESENTATION OF CASE: We report a case of a 67-year-old man who was brought to the emergency department after falling down a 14-step staircase at home which presented right kidney trauma (parenchyma laceration with a perirenal hematoma) on computed tomography, and hematuria. Considering the patient's hemodynamic stability, a non-operative treatment was initiated, and the patient was referred to the intensive care unit for close observation. On post-trauma day 3, a repeated CT revealed right renal vein thrombosis. After evaluation, it was decided to maintain prophylactic anticoagulation doses of enoxaparin (40 mg/day) due to the elevated risk of bleeding in high-grade renal trauma and planned an inferior vena cava (IVC) filter placement. In the following days, the hematuria resolved spontaneously and an IVC filter was placed. The patient progressed with no complaints, spontaneous diuresis, improvement in laboratory parameters, and cardiovascular stability, which led to his discharge on day 12 with rivaroxaban 10 mg/day. The patient was successfully treated with a non-operative approach, and the RVT disappeared after 35 days. DISCUSSION: Post-traumatic renal vein thrombosis is a rare occurrence, and due to the infrequent nature of these events, specific management guidelines are not fully established, particularly when thrombosis is confirmed in an acutely injured patient. CONCLUSION: Conservative therapy seems to play a meaningful role in trauma-related renal vein thrombosis treatment.

RESUMO Introdução: Queimaduras representam um componente fundamental do trauma no Brasil, sendo responsáveis por 2 milhões de incidentes e 2.500 mortes anualmente. Queimaduras autointencionais estão associadas a pior prognóstico, maior superfície corporal queimada, maiores taxas de infecção e morte. A falta de estudos sobre a problemática da autoimolação levanta questões epidemiológicas em relação às vítimas brasileiras. O estudo se objetivou investigar o perfil das queimaduras associados ao comportamento autolesivo entre vítimas brasileiras. Métodos: Esta revisão sistemática foi realizada de acordo com as diretrizes PRISMA 2020 e avaliou a correlação entre comportamento autolesivo como causa de queimaduras em vítimas brasileiras e suas implicações epidemiológicas nos últimos 20 anos (2003-2023). Os termos MeSH "Burns", "Self-Injurious Behavior", "Epidemiology" e "Brazil" foram elencados no PubMed/MEDLINE, SciELO e Cochrane Library e, após seleção por critérios de inclusão/exclusão, os estudos mais relevantes foram analisados criticamente. Resultados: Dos 1.077 estudos pré-selecionados, 92 foram potencialmente elegíveis, resultando em 7 manuscritos incorporados nesta revisão. Das 3.510 vítimas queimadas reunidas no conjunto de estudos selecionados, 311 casos apresentaram comportamento autolesivo. Pacientes que tentaram autoimolação apresentam maior risco de morte (p<0,05; RR=5,1 [3,2-8,1]) e maior superfície corporal queimada (p<0,05; MD=19,2 [10-28,2]), em comparação com casos acidentais. Ademais, o sexo feminino apresentou maior risco para tentativa de autoimolação (p<0,05; RR=4,01 [2,9-5,5]). Conclusão: Nossos resultados mostram que os casos de queimaduras autoprovocadas foram associados a uma maior área de superfície corporal queimada e a um maior risco de morte, e o sexo feminino foi identificado como um fator de risco relevante no Brasil.

RESUMO

Background: Short period from diagnosis to breast cancer (BC) treatment initiation remains challenging for the public health system in Brazil, which may have been further affected by the coronavirus disease-2019 (COVID-19) pandemic. This study assessed BC diagnosis-to-treatment intervals (DTi) in Brazil and the possible effects of the COVID-19 outbreak on delays. Methods: The Painel de Monitoramento de Tratamento Oncológico database was queried to obtain the number of Brazilian patients with a BC confirmed diagnosis and initiating cancer treatment in the pre-COVID-19 (2013-2019) and during the COVID-19 (2020-2021) periods, adopting a 60-day limit as timely treatment. A p-value of <0.05 was considered significant. Results: A total of 315,951 cases were included (females: 99.3% and males: 0.7%), of which 251,667 and 64,284 records were computed before and during the COVID-19 years, respectively. Most patients failed to perform the first cancer treatment within 60 days (>60: 51.8%). We observed an upward trend in the number of BC treatments provided in the pre-COVID-19 years (r2 = 0.9575; p < 0.05), but the volume of treatments exhibited an average reduction of 24.6% yearly during the COVID-19 pandemic. The average DTi in days was 122.4, 122.5 and 122.3 in the total period studied, before and during the COVID-19 outbreak, respectively. The arrival of COVID-19 in Brazil increased the chances of treatment delay (OR = 1.043; p < 0.05) and inverted the proportion of early/advanced stages at BC diagnosis (55.8%/44.2%-48.4%/51.6%). Conclusion: COVID-19 has imposed changes in BC care in Brazil, reducing the number of treatments provided by the Brazilian public health system, increasing the chances of delayed treatment initiation despite no differences in DTi averages being identified, and raising the proportion of advanced-stage diagnoses.

RESUMO

As the coronavirus disease 2019 (COVID-19) outbreak spread, evidence has emerged that gender and race would bear a disproportionate impact on the morbimortality of COVID-19. Here, we conducted a retrospective observational study using the TabNet/Departamento de informática do sistema único de saúde platform of the city of São Paulo. COVID-19 records from March 2020 through December 2021 were included, and we evaluated the temporal trends of confirmed cases and case fatality rate by gender and ethnicity. Statistical analysis was performed using the R-software and BioEstat-software, considering p < 0.05 significant. From March/2020 to December/2021, 1 315 160 COVID-19 confirmed cases were recorded (57.1% females), and 2973 deaths were due to COVID-19. Males presented higher median mortality (0.44% vs. 0.23%; p < 0.05) and intensive care unit (ICU) admission rates (0.34% vs. 0.20%; p < 0.05). Men were also associated with a higher risk of death (risk ratio [RR] = 1.28; p < 0.05) and a higher chance of requiring ICU care (RR = 1.29; p < 0.05). Black ethnicity was associated with a higher risk of death (RR = 1.19; p < 0.05). White patients were more likely to require ICU admission (RR = 1.13; p < 0.05), whereas Browns were associated with a protective effect (RR = 0.86; p < 0.05). Furthermore, men presented a higher chance of death than women across the three major ethnic groups: Whites (RR = 1.33; p < 0.05), Blacks (RR = 1.24; p < 0.05), and Browns (RR = 1.35; p < 0.05). In this study of COVID-19 in São Paulo, men were associated with worse outcomes, including in the three major ethnicities in the population. Blacks exhibited a higher risk of death, Whites were more likely to require intensive care, and Browns were at protection from ICU hospitalization.

RESUMO

AIM: Gallbladder diseases (GBD) are one of the most common medical conditions requiring surgical intervention, both electively and urgently. It is widely accepted that sex and ethnic characteristics mighty influence both prevalence and outcomes. This study aimed to evaluate the differences on distributions of gender and ethnicity related to the epidemiology of GBD in the Brazilian public health system. METHODS: DATASUS was used to retrieve patients' data recorded under the International Code of Diseases (ICD-10) - code K80 from January 2008 to December 2019. The number of admissions, modality of care, number of deaths, and in-hospital mortality rate were analyzed by gender and ethnic groups. RESULTS: Between 2008 and 2019, a total of 2,899,712 patients with cholelithiasis/cholecystitis (K80) were admitted to the hospitals of the Brazilian Unified Health System, of whom only 22.7% were males. Yet, the in-hospital mortality rate was significantly higher in males (15.9 per 1,000 male patients) than females (6.3 per 1,000 female patients) (p<0.05). Moreover, men presented a significantly higher risk of death (RR=2.5; p<0.05) and longer hospital stay (4.4 days vs. 3.3 days; p<0.05) than females. Compared to females, men presented a higher risk of death across all self-declared ethnic groups: whites (RR=2.4; p<0.05), blacks (RR=2.7; p<0.05), browns (RR=2.6; p<0.05), and Brazilian Indians (RR=2.13; p<0.05). CONCLUSION: In the years 2008-2019, women presented the highest prevalence of hospital admissions for GBD in Brazil, and men were associated with worse outcomes, including all ethnic groups.

RESUMO - RACIONAL: Doenças da vesícula biliar (DVB) são uma das condições médicas mais comuns que requerem intervenção cirúrgica, tanto eletiva como urgente. É amplamente aceito que o sexo e as características étnicas podem influenciar a prevalência e os desfechos. OBJETIVO: Avaliar as diferenças nas distribuições de gênero e etnia relacionados à epidemiologia da DVB no sistema público de saúde brasileiro. MÉTODOS: O DATASUS foi usado para elencar os dados de pacientes registrados no Código Internacional de Doenças (CID-10) sob o código K80, de janeiro de 2008 a dezembro de 2019. O número de admissões, caráter de atendimento, número de óbitos e taxa de mortalidade hospitalar foram analisados por gênero e por etnia. RESULTADO: Entre 2008 e 2019, 2.899.712 pacientes com colelitíase/colecistite (K80) foram admitidos em hospitais do Sistema Único de Saúde (SUS), dos quais apenas 22,7% eram do sexo masculino. Ainda assim, a taxa de mortalidade intra-hospitalar masculina (15,9:1.000 pacientes homens) foi significativamente maior do que a feminina (6,3:1.000 pacientes mulheres) (p<0,05). Ademais, homens apresentaram risco de morte significativamente maior em comparação às mulheres (RR=2,5; p<0,05) e maior tempo de internação hospitalar (4,4 dias versus 3,3 dias; p<0,05). Em comparação ao sexo feminino, homens apresentaram maior risco de morte em todos os grupos étnicos autodeclarados: brancos (RR=2,4; p<0,05), negros (RR=2,7; p<0,05), pardos (RR=2,6; p<0,05) e indígena (RR=2,13; p<0,05). CONCLUSÃO: Nos anos de 2008-2019, as mulheres apresentaram as maiores prevalências de internações hospitalares por DVB no Brasil, porém, os homens foram associados a piores desfechos, inclusive entre todos os grupos étnicos.

RESUMO

Acute appendicitis is the leading cause of abdominal emergency surgery worldwide and appendectomy continues to be the definitive treatment of choice. This cost-effectiveness analysis evaluates laparoscopic versus open appendectomies performed in public health services in the state of Bahia (Brazil). We conducted a retrospective observational study using the database from the Department of Informatics of the Unified Health System (DATASUS). Available data on appendectomies between 2008 and 2019 were included, and we evaluated the temporal trend of hospital admissions, procedure-related mortality rates, length of stay, and costs. Statistical analysis was performed using the R-software (R Foundation, v.4.0.3) and the BioEstat software (IMDS, v. 5.3), considering p<0.05 as significant. During 2008-2019, 53,024 appendectomies were performed in the public health services in Bahia, of which 94.9% were open surgeries. The open technique was associated with a higher mortality rate (4.9/1,000 procedures; p<0.05) and a higher risk of death (RR=4.5; p<0.05) compared to laparoscopy (1.1/1,000 procedures). Laparoscopic appendectomy (median of 2.7 days) had a shorter length of stay compared to laparotomy (median of 4.15 days) (p<0.05). There was no difference in the medians of costs nor hospital services, per procedure (p=0.08 and p=0.08, respectively). Laparoscopic professional median costs were higher by US$ 1.39 (p<0.05). Minimally invasive surgery for appendicitis is a safe and efficacious procedure in Brazilian public health care services, as it provides advantages over the open method (including lower procedure-related mortality rate and earlier discharges), and it did not imply higher expenses for public service budgets in the state of Bahia.

RESUMO

BACKGROUND: Screening mammography for breast cancer (BC) is a current strategy that reduces the mortality of BC by up to 30 %. Although mastectomy has been an important component of treatment for decades, conservative surgery (lumpectomy) has become the gold-standard approach for most cases, yet it depends on early detection of the BC. METHODS: This was an epidemiological study performed through DATASUS (2010-2018). We evaluated the temporal trend of screening mammograms, deaths from BC, and surgical procedures at national, regional and state levels. Statistical analysis was performed on VassarStat®-Website for Statistical Computation (Vassar College, New York, USA) and the R-software (R Foundation, v.4.0.3). RESULTS: During 2010-2018 there were 67,392 oncological mastectomies and 48,567 lumpectomies in Brazil's health system. Mastectomies decreased in the Northeast (-3.67 % ± 0.43 per year) and in Bahia state (-3.58 % ± 0.24 per year). Lumpectomies increased in Brazil (median 2.19 (-9.6 to 20.96)), the Northeast (median -12.07 (-25.8 to 9.43)) and Bahia (median 0.16 (-29.1 to 1.9)). Also, screening mammograms increased in Brazil (3.29 % ± 0.43), the Northeast (6.36 % ± 0.49) and Bahia (5.51 % ± 0.31), with 35,317,728 exams during this period. Deaths from BC increased annually in Brazil (+4.13 % ± 0.86), the Northeast (+4.76 % ± 1.45) and Bahia (+5.65 % ± 0.83). CONCLUSION: The number of mammograms related to the screening program increased in the years 2010-2018 in Brazil. Furthermore, we identified an increase in lumpectomies as opposed to mastectomies, and this approach is associated with a reduction in hospitalization days by almost a half, which in turn might result in a cost decrease and probably an earlier return to work.

RESUMO

Betulinic acid (BA, 3ß-hydroxy-lup-20(29)-en-28-oic acid) is a pentacyclic triterpene acid present predominantly in Betula ssp. (Betulaceae) and is also widely spread in many species belonging to different plant families. BA presents a wide spectrum of remarkable pharmacological properties, such as cytotoxic, anti-HIV, anti-inflammatory, antidiabetic and antimicrobial activities, including antiprotozoal effects. The present review first describes the sources of BA and discusses the chemical strategies to produce this molecule starting from betulin, its natural precursor. Next, the antiprotozoal properties of BA are briefly discussed and the chemical strategies for the synthesis of analogues displaying antiplasmodial, antileishmanial and antitrypanosomal activities are systematically presented. The antiplasmodial activity described for BA was moderate, nevertheless, some C-3 position acylated analogues showed an improvement of this activity and the hybrid models-with artesunic acid-showed the most interesting properties. Some analogues also presented more intense antileishmanial activities compared with BA, and, in addition to these, heterocycles fused to C-2/C-3 positions and amide derivatives were the most promising analogues. Regarding the antitrypanosomal activity, some interesting antitrypanosomal derivatives were prepared by amide formation at the C-28 carboxylic group of the lupane skeleton. Considering that BA can be produced either by isolation of different plant extracts or by chemical transformation of betulin, easily obtained from Betula ssp., it could be said that BA is a molecule of great interest as a starting material for the synthesis of novel antiprotozoal agents.

RESUMO

BACKGROUND: Arterial diseases represent a severe public health problem in the 21st century. Although men have a higher overall prevalence, reports have suggested that women may exhibit atypical manifestations, be asymptomatic, and have hormonal peculiarities, resulting in worse outcomes and severe emergencies, such as acute limb ischemia (ALI). OBJECTIVES: To analyze the morbidity and mortality profile of ALI emergencies in Brazil between 2008 and 2019. METHODS: An ecological study was carried out with secondary data from SIH/SUS, using ICD-10 code I.74 The proportions of emergency hospital admissions and in-hospital mortality rates (HMR) by gender, ethnicity, and age were extracted from the overall figures. P<0.05 was considered significant. RESULTS: From 2008 to 2019, there were 195,567 urgent hospitalizations due to ALI in Brazil, 111,145 (56.8%) of which were of men. Women had a higher HMR (112:1,000 hospitalizations) than men (85:1,000 hospitalizations) (p<0.05), and a higher chance of death (OR=1.36; p<0.05). Furthermore, mean survival was significantly higher among men (8,483/year versus 6,254/year; p<0.05). Stratified by ethnicity, women who self-identified as white (OR=1.44; p<0.05), black (OR=1.33; p<0.05), and brown (RR=1.25; p <0.05) had greater chances of death than men in the same ethnicity categories. Moreover, women over the age of 50 years had a higher chance of death, with a progressive increment in risk as age increased. CONCLUSIONS: There was a trend to worse prognosis in ALI emergencies associated with women, especially in older groups. The literature shows that the reasons for these differences are still poorly investigated and more robust studies of this relevant disease in the area of vascular surgery are encouraged.


CONTEXTO: Doenças arteriais representam um grave problema de saúde pública no século XXI. Apesar de homens apresentarem maior prevalência geral, estudos sugerem que mulheres podem cursar com quadros assintomáticos, clínica atípica e particularidades hormonais, que resultam em desfechos desfavoráveis e urgências graves, como oclusões arteriais aguda (OAA). OBJETIVOS: Analisar o perfil de morbimortalidade das urgências em OAA no Brasil entre 2008 e 2019. MÉTODOS: Realizou-se estudo ecológico com dados secundários do Sistema de Informações Hospitalares/Sistema Único de Saúde, utilizando-se o código I.74 do Código Internacional de Doenças-10. Dos números absolutos, obteve-se proporções de internamentos de urgência e taxa de mortalidade intra-hospitalar (TMH) por gênero, etnia e idade. Considerou-se p < 0,05 significativo. RESULTADOS: Entre 2008 e 2019, houve 195.567 internamentos de urgência por OAA no Brasil, dos quais 111.145 (56,8%) eram homens. Mulheres tiveram maior TMH (112:1.000 hospitalizações) em comparação a homens (85:1.000 hospitalizações) (p < 0,05), assim como maior chance de morte (odds ratio [OR] = 1,36; p < 0,05). Ademais, a média de sobrevida anual foi maior entre homens do que entre mulheres (8.483/ano vs. 6.254/ano, respectivamente; p < 0,05). Estratificando por etnia, mulheres apresentaram maior chance de óbitos entre brancas (OR = 1,44; p < 0,05), pretas (OR = 1,33; p < 0,05) e pardas (razão de risco [RR] = 1,25; p < 0,05), comparadas a homens das mesmas etnias. Nas análises etárias, mulheres com mais de 50 anos apresentaram maior chance de óbito, com aumento progressivo do risco com o envelhecimento. CONCLUSÕES: Nossas análises comparativas evidenciaram tendência de pior prognóstico nas urgências em OAA associadas a mulheres, sobretudo em grupos de idade avançada. A literatura evidencia que as razões para essas diferenças ainda são pouco estudadas, estimulando investigações mais robustas sobre essa importante casuística da cirurgia vascular.

RESUMO

ABSTRACT Acute appendicitis is the leading cause of abdominal emergency surgery worldwide and appendectomy continues to be the definitive treatment of choice. This cost-effectiveness analysis evaluates laparoscopic versus open appendectomies performed in public health services in the state of Bahia (Brazil). We conducted a retrospective observational study using the database from the Department of Informatics of the Unified Health System (DATASUS). Available data on appendectomies between 2008 and 2019 were included, and we evaluated the temporal trend of hospital admissions, procedure-related mortality rates, length of stay, and costs. Statistical analysis was performed using the R-software (R Foundation, v.4.0.3) and the BioEstat software (IMDS, v. 5.3), considering p<0.05 as significant. During 2008-2019, 53,024 appendectomies were performed in the public health services in Bahia, of which 94.9% were open surgeries. The open technique was associated with a higher mortality rate (4.9/1,000 procedures; p<0.05) and a higher risk of death (RR=4.5; p<0.05) compared to laparoscopy (1.1/1,000 procedures). Laparoscopic appendectomy (median of 2.7 days) had a shorter length of stay compared to laparotomy (median of 4.15 days) (p<0.05). There was no difference in the medians of costs nor hospital services, per procedure (p=0.08 and p=0.08, respectively). Laparoscopic professional median costs were higher by US$ 1.39 (p<0.05). Minimally invasive surgery for appendicitis is a safe and efficacious procedure in Brazilian public health care services, as it provides advantages over the open method (including lower procedure-related mortality rate and earlier discharges), and it did not imply higher expenses for public service budgets in the state of Bahia.


RESUMO Apendicite aguda é a principal causa de cirurgia abdominal de emergência no mundo e a apendicectomia continua sendo o tratamento definitivo de escolha. A presente investigação avalia desfechos e custos das apendicectomias laparoscópicas versus abertas realizadas em serviços públicos de saúde no estado da Bahia (Brasil). Realizou-se estudo observacional retrospectivo, utilizando a base de dados do DATASUS. Incluiu-se dados disponíveis sobre apendicectomias na Bahia entre 2008 e 2019, avaliando-se a tendência temporal de internações, taxas de mortalidade por procedimentos, tempo de permanência e custos. A análise estatística foi realizada no R-software (Fundação R, v.4.0.3) e no software BioEstat (IMDS, v.5.3), considerando p<0,05 significativo. Entre 2008 e 2019, realizou-se 53.024 apendicectomias no serviço público de saúde na Bahia, das quais 94,9% foram cirurgias abertas. A laparotomia foi associada à maior taxa de mortalidade (4,9/1.000 procedimentos; p<0,05) e maior risco de morte (RR=4,5; p<0,05) do que laparoscopia (1,1/1.000 procedimentos). Apendicectomia laparoscópica (mediana de 2,7 dias) obteve menor tempo de internamento do que cirurgia laparotômica (mediana de 4,15 dias) (p<0,05). Não houve diferença entre as medianas dos custos e nem dos serviços hospitalares por procedimento (p=0,08 e p=0,08, respectivamente). A mediana do custo de profissionais na laparoscopia foi significativamente mais elevada, em US$ 1,39 (p<0,05). A cirurgia minimamente invasiva para apendicite é um procedimento seguro e eficaz, proporcionando vantagens sobre a laparotomia (incluindo menor taxa de mortalidade e alta precoce), não implicando, por sua vez, em maiores despesas para cofres públicos no estado da Bahia.

RESUMO

PURPOSE: Civil violence is responsible for 2.5% of deaths worldwide; it killed more people in the 21st century than the sum of all wars. This study describes violence victims treated at a trauma reference hospital in Salvador, Brazil and analyzes the impact of different types of interpersonal violence. METHODS: Interpersonal violence victims admitted between July 2015 and July 2017 were included. The 1,296 patients (mean age: 30.3 years; 90% male) were divided into three groups according to the mechanism of interpersonal violence: 1) beating, 2) firearm injury and 3) stab wound (STW) injury. The groups were compared for the following variables: age, gender, trauma mechanism, Revised Trauma Score (RTS) at admission, need for intensive care unit (ICU) attention, length of hospital stay, need for transfusion of blood products and death. RESULTS: Gunshot wounds (GSW) were the primary mechanism of injury (59%), followed by beating (24%) and STW (17%). Gunshot wound victims had a lower mean RTS upon admission, increased need for blood products and more Intensive Care Unit (ICU) admissions. Beating victims had the longest mean hospital stay (11.6 ± 19.6 days). The GSW group accounted for 77.4% of all deaths. The in-hospital mortality rate was significantly higher in the GSW group (12.7%) than in the beating group (5.4%) and in the STW group (4.9%). CONCLUSIONS: Gunshot wound victims are more critical: they require longer ICU stays, more transfusions of blood products and exhibit increased mortality compared with STW and beating victims.


OBJETIVO: a violência civil é responsável por 2,5% da mortalidade mundial, matou mais pessoas no século XXI do que o somatório de todas as guerras deste período. Este estudo descreve as vítimas de violência admitidas em um hospital de referência em trauma em Salvador - Bahia, Brasil e analisa o impacto dos diferentes tipos de violência interpessoal. MÉTODOS: foram incluídos vítimas de violência interpessoal admitidas entre julho de 2015 e julho de 2017. 1296 pacientes (média de idade foi 30,3 anos, 90% do sexo masculino) foram divididos em três grupos de acordo com o mecanismo de violência interpessoal: espancamento, ferimentos por projétil de arma de fogo (FPAF), ferimentos por arma branca (FAB). Os grupos foram comparados de acordo com as seguintes variáveis: idade, sexo, mecanismo de trauma, Revised Trauma Score (RTS) na admissão, necessidade de internamento em unidade de tratamento intensivo (UTI), tempo de internamento, necessidade de transfusão de hemocomponentes e morte. RESULTADOS: FPAF foram o principal mecanismo de injúria (59%), seguido por agressão (24%) e FAB (17%). As vítimas de FPAF apresentaram a menor média de RTS na admissão, maior necessidade de uso de hemocomponentes e de internamento em UTI. Vítimas de espancamento tiveram a maior média de duração de internação hospitalar (11,6±19,6 dias). Os FPAF causaram 77,4% das mortes. CONCLUSÃO: vítimas de FPAF são mais críticas, requerendo maior tempo de tratamento em UTI, mais hemocomponentes e maior mortalidade comparativamente às vítimas de FAB e espancamento.
