Acessos vasculares para Hemodiálise no Ceará-Brasil

Backgroung: the ideal access for hemodialysis is represented by arteriovenous fistulas both as initial access and in use and are determinants of health care parameters for chronic renal patients. Objective: to evaluate vascular access for hemodialysis. Methods: this is a cross-sectional study, with a sample of 2513 individuals on hemodialysis in Ceará. Data were collected on age, sex, time of treatment, underlying disease, initial access and access in use. The data were divided into two groups, the interior of the state and the Metropolitan Region of Fortaleza, in the State of Ceará, and compared using the Student’s Test (p<0.05). Results: the most common age group was between 19 and 64 years (73%). Men prevailed in both regions, 713 (63%) in the countryside and 792 (57%) in the metropolitan area. The most common cause of Chronic Kidney Disease was Hypertension 306 (27%), followed by Disease of undetermined cause 295 (26%) in the countryside; in the metropolitan region, Diabetes Mellitus 356 (26%) was the main cause, followed by Hypertension and Disease of undetermined cause, each with 344 (25%), p=0.001. In the countryside, 9% started treatment for fistula while in the metropolitan area 12%, p=0.011. 79% of patients in the countryside used fistulas and 81% in the metropolitan area, p=0.156. Conclusion: arteriovenous fistulas are more frequent as initial accesses in the metropolitan region than in the interior, but there is an equivalence of fistulas in use in both regions. Catheter is the main initial access route. The evaluation of vascular accesses in Ceará showed that hemodialysis services are able to maintain good parameters of care for patients with chronic kidney disease.Introdução: o acesso ideal para hemodiálise é representado por fístulas arteriovenosas tanto como acesso inicial quanto em uso e são determinantes de parâmetros de atenção à saúde do paciente renal crônico.

Piomiosite tropical: diabetes facilitando o aparecimento de uma doença incomum

Introdução: A piomiosite tropical é uma doença infecciosa que afeta o músculo esquelético, aparecendo como uma inflamação difusa ou um processo mionecrótico rapidamente progressivo. A predisposição desta enfermidade em diabéticos já é referida em vários estudos. A patogênese possivelmente está relacionada a alterações nos neutrófilos e na inversão do padrão de resposta imune que acontece em situações como parasitoses. Staphylococcus aureus é o microorganismo mais comum, representando 90% dos casos de piomiosite tropical. O diagnóstico pode ser tardio porque os pacientes geralmente não buscam cuidados com os primeiros sintomas e, por ser uma doença rara, pode surpreender um médico ainda não familiarizado com esta entidade clínica. Relato de caso: Paciente do sexo masculino com 42 anos de idade com diabetes mellitus, hipotireoidismo, anemia, trombocitopenia e hipoalbuminemia que desenvolveu piomiosite tropical com múltiplos abscessos musculares em quadríceps, sóleo e tibial anterior, tríceps e bíceps braquial e pronador redondo, necessitando de antibioticoterapia prolongada e drenagem cirúrgica. Conclusão: A piomiosite não é uma doença bem conhecida e pode ser fatal se não for diagnosticada precocemente

Low Grade Myofibroblastic Sarcoma Of The Breast: Case Report And Review Of The Literature

Background: Myofibroblastic sarcomas of the breast are rare neoplasms, with aggressive behavior, wich mainly affects individuals 46-81 years old, predominantly females. They are malignant tumors composed of myofibroblasts, cells with an important role in inflammatory processes.Methods and Findings:  This study, which was performed at the Hospital Geral Waldemar de Alcântara (Waldemar de Alcântara General Hospital) of the city of Fortaleza / Ceará / Brazil, reports a case of myofibroblastic sarcoma of the breast and conducts a literature review on the subject. It is about a female patient, 51, who presented, on the left breast, a mass of rapid growth, which reached about 20 cm (7,9 inches). The diagnosis was confirmed by histology and immunohistochemistry of material obtained by incisional biopsy of the lesion, showing up non-metastatic myofibrosarcoma of the breast. The treatment was simple left mastectomy and adjuvant radiotherapy, with follow-up every six months. Since this type of cancer is rare, treatment is not well established, so more studies are needed on this subject.Conclusion: The current consensus is the complete excision of the lesion; adjuvant radiotherapy and chemotherapy may be performed. This is one of the few cases of mammary myofibrosarcoma reported in the literature and contributes to the recognition of this rare type of tumor.

Association of Country Income Level With the Characteristics and Outcomes of Critically Ill Patients Hospitalized With Acute Kidney Injury and COVID-19

Introduction: Acute kidney injury (AKI) has been identified as one of the most common and significant problems in hospitalized patients with COVID-19. However, studies examining the relationship between COVID-19 and AKI in low- and low-middle income countries (LLMIC) are lacking. Given that AKI is known to carry a higher mortality rate in these countries, it is important to understand differences in this population. Methods: This prospective, observational study examines the AKI incidence and characteristics of 32,210 patients with COVID-19 from 49 countries across all income levels who were admitted to an intensive care unit during their hospital stay. Results: Among patients with COVID-19 admitted to the intensive care unit, AKI incidence was highest in patients in LLMIC, followed by patients in upper-middle income countries (UMIC) and high-income countries (HIC) (53%, 38%, and 30%, respectively), whereas dialysis rates were lowest among patients with AKI from LLMIC and highest among those from HIC (27% vs. 45%). Patients with AKI in LLMIC had the largest proportion of community-acquired AKI (CA-AKI) and highest rate of in-hospital death (79% vs. 54% in HIC and 66% in UMIC). The association between AKI, being from LLMIC and in-hospital death persisted even after adjusting for disease severity. Conclusions: AKI is a particularly devastating complication of COVID-19 among patients from poorer nations where the gaps in accessibility and quality of healthcare delivery have a major impact on patient outcomes

Thrombotic and hemorrhagic complications of COVID-19 in adults hospitalized in high-income countries compared with those in adults hospitalized in low- and middle-income countries in an international registry

Background: COVID-19 has been associated with a broad range of thromboembolic, ischemic, and hemorrhagic complications (coagulopathy complications). Most studies have focused on patients with severe disease from high-income countries (HICs). Objectives: The main aims were to compare the frequency of coagulopathy complications in developing countries (low- and middle-income countries [LMICs]) with those in HICs, delineate the frequency across a range of treatment levels, and determine associations with in-hospital mortality. Methods: Adult patients enrolled in an observational, multinational registry, the International Severe Acute Respiratory and Emerging Infections COVID-19 study, between January 1, 2020, and September 15, 2021, met inclusion criteria, including admission to a hospital for laboratory-confirmed, acute COVID-19 and data on complications and survival. The advanced-treatment cohort received care, such as admission to the intensive care unit, mechanical ventilation, or inotropes or vasopressors; the basic-treatment cohort did not receive any of these interventions. Results: The study population included 495,682 patients from 52 countries, with 63% from LMICs and 85% in the basic treatment cohort. The frequency of coagulopathy complications was higher in HICs (0.76%-3.4%) than in LMICs (0.09%-1.22%). Complications were more frequent in the advanced-treatment cohort than in the basic-treatment cohort. Coagulopathy complications were associated with increased in-hospital mortality (odds ratio, 1.58; 95% CI, 1.52-1.64). The increased mortality associated with these complications was higher in LMICs (58.5%) than in HICs (35.4%). After controlling for coagulopathy complications, treatment intensity, and multiple other factors, the mortality was higher among patients in LMICs than among patients in HICs (odds ratio, 1.45; 95% CI, 1.39-1.51). Conclusion: In a large, international registry of patients hospitalized for COVID-19, coagulopathy complications were more frequent in HICs than in LMICs (developing countries). Increased mortality associated with coagulopathy complications was of a greater magnitude among patients in LMICs. Additional research is needed regarding timely diagnosis of and intervention for coagulation derangements associated with COVID-19, particularly for limited-resource settings

Characteristics and outcomes of an international cohort of 600 000 hospitalized patients with COVID-19

Background: We describe demographic features, treatments and clinical outcomes in the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) COVID-19 cohort, one of the world's largest international, standardized data sets concerning hospitalized patients. Methods: The data set analysed includes COVID-19 patients hospitalized between January 2020 and January 2022 in 52 countries. We investigated how symptoms on admission, co-morbidities, risk factors and treatments varied by age, sex and other characteristics. We used Cox regression models to investigate associations between demographics, symptoms, co-morbidities and other factors with risk of death, admission to an intensive care unit (ICU) and invasive mechanical ventilation (IMV). Results: Data were available for 689 572 patients with laboratory-confirmed (91.1%) or clinically diagnosed (8.9%) SARS-CoV-2 infection from 52 countries. Age [adjusted hazard ratio per 10 years 1.49 (95% CI 1.48, 1.49)] and male sex [1.23 (1.21, 1.24)] were associated with a higher risk of death. Rates of admission to an ICU and use of IMV increased with age up to age 60 years then dropped. Symptoms, co-morbidities and treatments varied by age and had varied associations with clinical outcomes. The case-fatality ratio varied by country partly due to differences in the clinical characteristics of recruited patients and was on average 21.5%. Conclusions: Age was the strongest determinant of risk of death, with a ∼30-fold difference between the oldest and youngest groups; each of the co-morbidities included was associated with up to an almost 2-fold increase in risk. Smoking and obesity were also associated with a higher risk of death. The size of our international database and the standardized data collection method make this study a comprehensive international description of COVID-19 clinical features. Our findings may inform strategies that involve prioritization of patients hospitalized with COVID-19 who have a higher risk of death

ISARIC-COVID-19 dataset: A Prospective, Standardized, Global Dataset of Patients Hospitalized with COVID-19

The International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) COVID-19 dataset is one of the largest international databases of prospectively collected clinical data on people hospitalized with COVID-19. This dataset was compiled during the COVID-19 pandemic by a network of hospitals that collect data using the ISARIC-World Health Organization Clinical Characterization Protocol and data tools. The database includes data from more than 705,000 patients, collected in more than 60 countries and 1,500 centres worldwide. Patient data are available from acute hospital admissions with COVID-19 and outpatient follow-ups. The data include signs and symptoms, pre-existing comorbidities, vital signs, chronic and acute treatments, complications, dates of hospitalization and discharge, mortality, viral strains, vaccination status, and other data. Here, we present the dataset characteristics, explain its architecture and how to gain access, and provide tools to facilitate its use
