Population-level risks of alcohol consumption by amount, geography, age, sex, and year: a systematic analysis for the Global Burden of Disease Study 2020

Background The health risks associated with moderate alcohol consumption continue to be debated. Small amounts of alcohol might lower the risk of some health outcomes but increase the risk of others, suggesting that the overall risk depends, in part, on background disease rates, which vary by region, age, sex, and year. Methods For this analysis, we constructed burden-weighted dose–response relative risk curves across 22 health outcomes to estimate the theoretical minimum risk exposure level (TMREL) and non-drinker equivalence (NDE), the consumption level at which the health risk is equivalent to that of a non-drinker, using disease rates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2020 for 21 regions, including 204 countries and territories, by 5-year age group, sex, and year for individuals aged 15–95 years and older from 1990 to 2020. Based on the NDE, we quantified the population consuming harmful amounts of alcohol. Findings The burden-weighted relative risk curves for alcohol use varied by region and age. Among individuals aged 15–39 years in 2020, the TMREL varied between 0 (95% uncertainty interval 0–0) and 0·603 (0·400–1·00) standard drinks per day, and the NDE varied between 0·002 (0–0) and 1·75 (0·698–4·30) standard drinks per day. Among individuals aged 40 years and older, the burden-weighted relative risk curve was J-shaped for all regions, with a 2020 TMREL that ranged from 0·114 (0–0·403) to 1·87 (0·500–3·30) standard drinks per day and an NDE that ranged between 0·193 (0–0·900) and 6·94 (3·40–8·30) standard drinks per day. Among individuals consuming harmful amounts of alcohol in 2020, 59·1% (54·3–65·4) were aged 15–39 years and 76·9% (73·0–81·3) were male. Interpretation There is strong evidence to support recommendations on alcohol consumption varying by age and location. Stronger interventions, particularly those tailored towards younger individuals, are needed to reduce the substantial global health loss attributable to alcohol.

Clinical, epidemiological, and etiological profile of inpatients with community-acquired pneumonia at a general hospital in the Sumare microregion of Brazil

Objective: To analyze the clinical, etiological, and epidemiological aspects of community-acquired pneumonia (CAP) in hospitalized individuals. Methods: We prospectively studied 66 patients (> 14 years of age) with CAP admitted to the Hospital Estadual Sumare, located in the Sumare microregion of Brazil, between October of 2005 and September of 2007. We collected data related to clinical history, physical examination, pneumonia severity index (PSI) scores, and laboratory tests (blood culture; sputum smear microscopy and culture; serology for Chlamydophila pneumoniae, Mycoplasma pneumoniae, and Legionella pneumophila; and detection of Legionella sp. and Streptococcus pneumoniae antigens in urine). Results: The mean age of patients was 53 years. Most had a low level of education, and 55.7% presented with at least one comorbidity at the time of hospitalization. The proportion of elderly people vaccinated against influenza was significantly lower among the inpatients than in the general population of the Sumare microregion (52.6% vs. > 70%). Fever was less common among the elderly patients (p < 0.05). The clinical evolution was associated with the PSI scores but not with age. The etiology was confirmed in 31 cases (50.8%) and was attributed to S. pneumoniae, principally detected by the urinary antigen test, in 21 (34.4%), followed by C. pneumoniae, in 5 (8.2%). The mortality rate was 4.9%, and 80.3% of the patients were classified as cured at discharge. Conclusions: The knowledge of the etiologic profile of CAP at the regional level favors the appropriate choice of empirical treatment, which is particularly relevant in elderly patients and in those with comorbidities. The lack of influenza vaccination in elderly patients is a risk factor for hospitalization due to CAP.37220020

Simultaneous bleeding and thrombosis in superwarfarin poisoning

Superwarfarin poisoning causes a severe acquired coagulation disorder that, despite its frequency, severity and specific therapeutic implications, stilt goes largely unrecognized by physicians. Hematologists are often called to evaluate these patients, but unawareness of the specificities of the problem often precludes adequate diagnosis and treatment. Superwarfarin poisoning differs from coumarin overdose in that the former is resistant to reversal with standard doses of vitamin K, and that anticoagulant effects can last for weeks after drug discontinuation. Here we report a case of superwarfarin poisoning with a previously unreported clinical presentation, in which diffuse bleeding and venous thrombosis were simultaneousty present at diagnosis. The diagnostic implications and the therapeutic dilemmas raised by this new presentation are discussed.123463763

Compartment syndrome after Bothrops jararaca snakebite: monitoring, treatment, and outcome

Objective. To report the outcome of a patient who developed compartment syndrome after Bothrops jararaca snakebite. Case report. A 39-year-old male was admitted 5 h after being bitten on the lower right leg. Physical examination revealed tense swelling, ecchymosis, hypoesthesia, and intense local pain that worsened after passive stretching, limited right foot dorsiflexion, and gingival bleeding. The case was classified as moderate/severe and eight vials of bothropic antivenom (AV) were infused 1 h postadmission. The main laboratory findings upon admission were incoagulable blood (incoagulable PT, aPTT, and INR), thrombocytopenia, serum creatine kinase (CK) of 580 U/L (reference value < 170 U/L), and a serum venom level of 33.7 ng/mL (ELISA; cutoff = 2.3 ng/mL). High anterior compartment pressure (60 mmHg) was identified 8 h post bite, with progressively lower pressures after AV administration and limb elevation (36 mmHg; 19 h post bite). However, moderate pain and limited foot dorsiflexion persisted. In addition, there was a progressive increase in serum CK (6,729 U/L; 45 h post bite), as well as marked edema and hemorrhage of the anterior compartment detected by magnetic resonance imaging (MRI) at 48 h post bite. A fasciotomy done after a further increase in intracompartmental pressure (66 mmHg, 57 h post bite) revealed hemorrhage/necrosis of the anterior tibial muscle that subsequently required partial resection. The patient developed a local infection (day 15 post bite) and a permanent fibular palsy. Conclusion. Compartment syndrome is an unusual but severe complication of snakebites. MRI, in conjunction with subfascial pressure measurements, may be useful in the diagnosis of compartment syndrome after snakebites.481576

Diagnosis, Evaluation, and Treatment of Lead Poisoning in General Population

Among the heavy metals, lead still remains the major toxic pollutant of the environment. Human exposure to lead can occur through numerous pathways including air, food, dust, soil, and water. In the present study 14 lead poisoned patients with non-occupational lead exposure were evaluated. They were followed up and compared against the controls with no history of lead exposure. The patients had high blood lead levels and symptoms of weakness, dizziness, abdominal pain, generalized body ache, loss of appetite, and anxiety. Repeated course of chelation therapy helped to bring down their body burden of lead. Alternative sources for lead exposure can cause severe lead poisoning in general population. Screening and medical management of such individuals is very important to identify and eliminate sources of lead. The treatment and management requires a thorough medical evaluation and environmental intervention

OBJETIVO: Apresentar, descrever e propor como método de treinamento e/ou aperfeiçoamento em colecistectomia videolaparoscópica, um modelo desenvolvido em cadáver de feto humano. MÉTODO: No Departamento de Morfologia da Faculdade de Medicina da Universidade Federal do Ceará foram utilizados 70 cadáveres de fetos humanos, de ambos sexos, frescos-congelados, com tamanhos entre 39 e 54 centímetros (média = 49cm) e pesos entre 1.210 e 3.900 gramas (média = 2.900g). Foi empregado, ainda, todo o arsenal de equipamentos e instrumentais de cirurgia videolaparoscópica. Cada feto foi submetido à videocolecistectomia experimental e os dados referentes aos aspectos técnicos e anatômicos registrados em fitas de vídeo e em protocolo para análise posterior. A técnica cirúrgica utilizada seguiu todos as etapas operatórias da videocolecistectomia in vivo. RESULTADOS: Foi possível manter um pneumoperitônio eficiente, em torno de 18mmHg, em todos os casos. A adequada clipagem do ducto cístico foi possível em 66 dos 68 casos operados, e da artéria cística em 62 casos. A vesícula foi extirpada satisfatoriamente em 67 fetos. O tempo cirúrgico médio foi de 70 minutos. Observou-se que o método proposto permite ao cirurgião adquirir, a partir de um treinamento adequado, habilidades técnicas, bem como segurança na execução de manobras necessárias para a prática desta modalidade cirúrgica. CONCLUSÃO: A videocolecistectomia em cadáver de feto humano representa um método factível, de grande importância, que pode ser aplicado no treinamento e/ou aperfeiçoamento de cirurgiões videolaparoscópicos
