A retrospective cohort study from a referral hospital assessed 385 pregnant women with chronic hypertension over a 5-year period (2012-2017). The data, collected by Gabriela Pravatta Rezende via medical chart review, describes maternal demographics, preeclampsia prophylaxis, and birth outcomes. Key findings include a 40% rate of superimposed preeclampsia and a mean gestational age at birth of 36 weeks.
Mariana Ferreira Sbrana's retrospective study analyzes recurrence and malignant transformation rates in patients with sinonasal inverted papilloma. The dataset covers 44 patients who underwent surgery at a tertiary hospital in São Paulo between August 1998 and August 2017. It includes data on patient demographics, tumor characteristics, Krouse staging, follow-up appointments, recurrence, and malignancy.
36 pediatric patients with a mean age of 7.14 months underwent perventricular device closure of ventricular septal defects via a transverse split sternotomy. The procedure was successful in 35 patients, with a mean hospital stay of 6.58 days and no in-hospital mortality. This dataset, associated with a paper by Pankaj Garg, reports surgical outcomes including complications, ventilation duration, and follow-up results over a mean period of 23.3 months.
20.6% of 320 institutionalized elderly participants were hospitalized over a 12-month follow-up period. This concurrent cohort study collected sociodemographic, health, nutritional, functional, and cognitive data from 10 long-term care institutions in Natal, RN, Brazil. The research was authored by Fabienne Louise Juvêncio Paes de Andrade and identifies malnutrition risk and cardiovascular drug use as significant risk factors for hospitalization.
A cross-sectional epidemiological study of 154 patients registered in the HIPERDIA program at Family Health Units. The dataset likely contains survey responses on demographics, oral hygiene habits, and perceptions of the relationship between diabetes and periodontal disease. The study was authored by João Nilton Lopes de Sousa and published via the paperswithcode platform.
Aline Silva de Aguiar's study includes data from 371 medical students across three federal universities in southeastern Brazil. The cross-sectional research collected sociodemographic data and applied scales to evaluate attitudes, knowledge, and alcohol consumption patterns. Results indicate 60.4% of students reported binge drinking, and 30.7% exhibited risk behavior for alcohol consumption.
A cross-sectional study of 40 outpatients with right ventricular pacemaker stimulation and preserved left ventricular ejection fraction. The research compares pacemaker-induced dyssynchrony among apical, medial septum, and free wall lead positions using echocardiogram and chest X-ray data. The study was authored by Ana Paula Susin Osório and is available via Open Access.
A clinical study comparing the effects of pharyngeal flap surgery and sphincteroplasty on hypernasality and velopharyngeal closure in 30 patients with repaired cleft palate. The dataset likely contains pre- and post-operative nasalance scores and velopharyngeal area measurements, with results indicating a statistically significant reduction in both metrics for both surgical groups. The study was authored by Renata Paciello Yamashita and sourced from the Papers with Code platform.
95 of 353 thyroid surgery patients at a Brazilian university hospital had well-differentiated thyroid carcinoma. Papillary carcinoma was the most frequent type, affecting women around age 49 more often. The study, authored by Ricardo Rocha, analyzed surgical outcomes and recurrence over a mean follow-up of 36.9 months.
A retrospective cohort of 1,296 patients with confirmed SARS-CoV-2 infection from San Ignacio University Hospital in Bogotá, Colombia. The dataset was used to analyze the relationship between prolonged QTc interval on admission electrocardiograms and in-hospital mortality, with results published by Stephany Barbosa. Data collection occurred between March 19, 2020, and July 31, 2021.
82 patients submitted to cardiac surgery with extracorporeal circulation were studied to test predictive factors for ICU stay length. The Logistic CASUS Score on the second postoperative day showed an area under the ROC curve of 0.723, performing better than serum bilirubin dosage. The study was authored by Marcio Fernandes Pimentel and is available via Open Access.
An innovative microfluidic technique achieved cell processing rates as high as 7.5×10⁶ cells per second. The method, developed at UCLA, uses microscale vortices to separate larger cancer cells from smaller blood cells based on size without mechanical filters. Viable long-term culture was established using cells collected off-chip, suggesting utility for clinical and research applications.
303 singleton pregnancies from a Chinese tertiary center between September 2022 and September 2025. This retrospective cohort study by Dan Fu integrates non-invasive prenatal testing (NIPT) results with second-trimester ultrasound soft markers to assess diagnostic accuracy for fetal chromosomal abnormalities.
31 glaucoma patients were treated with loteprednol etabonate eyedrops for one week before trabeculectomy surgery. The study by Nikoly T. Fares measured ocular surface disease before and after surgery using questionnaires, clinical exams, and keratograph analysis. Results showed a high prevalence of ocular surface disease and significant postoperative changes in conjunctival hyperemia and tear breakup time.
184 hypertensive patients with a mean age of 60.5 years participated in the development and validation of this psychometric instrument. The HIPER-Q questionnaire achieved a clarity index of 8.7, an intraclass correlation coefficient of 0.804, and a Cronbach's alpha of 0.648. Rafaella Zulianello dos Santos authored this research to provide a tool for assessing patient knowledge in cardiac rehabilitation programs.
A retrospective case series of 70 patients with ankle tumors, covering clinical and surgical treatment outcomes from 1990 to 2020. The data includes patient demographics, symptoms, diagnosis times, and recurrence rates, with a mean patient age of 21.7 years. The study was authored by Nathalia Sundin Palmeira de Oliveira and published via paperswithcode.
478 routine electroencephalogram recordings with simultaneous 2-lead electrocardiogram data from patients aged 16 to 95, collected between January and March 2016. The dataset was analyzed by cardiology specialist Halil Önder to investigate arrhythmia rates. Findings include ventricular extrasystole in 5.6% of patients and a 17% overall arrhythmia detection rate by cardiologist evaluation.
Six U.S. states' high-risk health insurance plan data from 1988 to 1991, collected by Sally C. Stearns of the University of North Carolina at Chapel Hill. The dataset includes enrollment, utilization, and cost information aggregated by person and month. It covers individuals who were medically uninsurable or unable to find affordable private coverage.
An observational study of 1,269 dyslipidemic individuals in Greece followed for a median of 6 years. The dataset, associated with a research paper by Fotios Barkas, examines the correlation between baseline uric acid levels and incident chronic kidney disease, adjusting for factors like age, gender, diabetes, and cardiovascular disease. 11.9% of the eligible cohort developed CKD during follow-up.
