An experiment evaluated the effects of early versus late calving seasons on 54 Red Angus primiparous cows at 24 months of age. The study measured calf weight gain, weaning weight, and pregnancy rates, finding higher efficiency for early calving cows. The dataset originates from research by Eduardo Madeira Castilho, published via Papers with Code.
2009 data from 1,191 confirmed severe cases of influenza A(H1N1)pdm09 among residents of Rio de Janeiro, Brazil. The dataset includes demographic, clinical, and outcome variables used to analyze factors associated with death. It was created by Gustavo Machado Felinto from secondary data analysis.
A study of 18 adult Campolina mares, aged six to fourteen years, with and without obesity, conducted by Jéssica Fontana de Magalhães. Radiographic measurements from the forelimbs were analyzed to evaluate the spatial relationship between the hoof capsule and the distal phalanx. The sinking distance of the distal phalanx was about 20% higher in obese mares and correlated with adiposity parameters.
321 milk samples from mammary glands without clinical signs were analyzed for somatic cell count, California Mastitis Test score, electrical conductivity, pH, chloride content, and bacteriological status. The study, authored by Alice Maria Melville Paiva Della Libera, calculated the predictive value of these indicators using bacteriological examination as the gold standard. Bacteriologic exam results showed 46.73% of samples were positive, with Staphylococcus sp. as the main isolated genus.
1,191 confirmed cases of Severe Acute Respiratory Infection (SARI) caused by influenza A(H1N1)pdm09 among residents of Rio de Janeiro in 2009. The data was analyzed by Gustavo Machado Felinto to study factors associated with death, including demographics, comorbidities, and radiological patterns. The analysis found a 7.4% mortality rate, with higher chances of death associated with low educational level, presence of comorbidity, and specific pulmonary radiological patterns.
776 medical students from a private Mexican university participated in a 2014 survey assessing depression, anxiety, and sleepiness. The dataset includes responses to standardized scales (PHQ-9, GAD-7, Epworth Sleepiness Scale) alongside demographic, academic, and health history variables. It was collected by Juan C. López Tavera.
A 2005-2015 literature review of voice papers in Brazilian Speech-Language Pathology journals, identifying publications on non-verbal communication. Telma Dias dos Santos performed the review, finding 342 voice papers, with 176 about voice professionals and only eight addressing non-verbal communication. The eight papers covered radio and television professionals, teachers, actors, and college students.
94 cerebrospinal fluid (CSF) samples from inpatients at Edgardo Rebagliati Martins Hospital in Peru, analyzed for physical, cytological, and chemical alterations. The study, authored by Eder Walttuoni-Picón, found the most frequent neurological disorders were encephalopathy (43%) and brain tumor (23%). It reports differences in protein concentration (p=0.001) between disorders but not in glucose concentration (p>0.05).
Medical records from 105 patients treated for acute arterial occlusions in limbs at a university hospital. The data includes patient demographics, etiology, symptoms, comorbidities, Rutherford categories, treatment details, and 30-day outcomes for limb salvage and mortality. The dataset was created by Caroline Teodoro as part of a retrospective cohort study.
Survey data from 103 health professionals in a mental hospital, evaluating patient safety culture using the Safety Attitudes Questionnaire (SAQ). The study was conducted by Isabelly Costa Lima de Oliveira as a cross-sectional analysis. The total safety culture score was 69 points, with domain scores ranging from 57 for Working Conditions to 80 for Job Satisfaction.
Tássia Moara Amorim authored a clinical study evaluating the impact of uveitis score on vision recovery in 34 dog eyes with various corneal ulcers treated via bulbar conjunctival pedicle graft. The dataset likely contains patient records from the study, including ulcer type, uveitis severity, and post-operative visual status. The overall success rate for vision recovery was reported as 73.52%.
60 patients with repaired cleft palate and residual velopharyngeal insufficiency were analyzed before and after secondary palatoplasty with intravelar veloplasty. The dataset includes perceptual hypernasality ratings on a 6-point scale and nasalance scores from nasometry, assessed pre-surgery and an average of 16 months post-surgery. The data was collected by Renata Paciello Yamashita to investigate the long-term effectiveness of the surgical procedure.
Letícia Assis Couto's study includes 40 individuals with fibromyalgia diagnosed under the 2010 American College of Rheumatology criteria. The dataset likely contains patient scores from the ASAS-R, VAS, WPI, SS, and FIQR questionnaires, measuring self-care agency, pain, symptom severity, and quality of life. Analysis used Pearson and Spearman correlation coefficients with a 5% significance level.
29 individuals affected by cerebrovascular accident were assessed for sexual function, quality of life, and functional independence. The observational study found 48.3% were sexually active, with 64.3% reporting decreased activity after stroke. Alianny Raphaely Rodrigues Pereira authored this cross-sectional research.
Seven elderly women participated in a clinical trial evaluating the effects of Pilates exercises on respiratory muscle strength. Emmanuel Dias de Sousa Lopes conducted the longitudinal study, which lasted eleven weeks and used spirometry and manometer measurements. Results showed a significant increase in maximal expiratory pressure from 46±18 to 75±29 cmH2O.
274 consecutive heart failure patients with left ventricular ejection fraction ≤ 40% were prospectively evaluated. The dataset likely contains cardiopulmonary exercise test parameters used to stratify risk for cardiac death or urgent heart transplantation over a 1-year follow-up. It was created by António Valentim Gonçalves and is available via Open Access.
A Brazilian secondary care center conducted a prospective, non-randomized study assessing pharmacist-led medication therapy management. The study included 66 patients with Alzheimer's disease, with 55 completing a six-month follow-up. Marcela Forgerini authored the research, which measured health outcomes like cognitive tests and blood pressure.
58.16% of surveyed dentistry students considered high caries risk and dentin hypersensitivity as the main factors for fluoride indication. This cross-sectional study evaluates knowledge about the rational use of fluoride among students from different semesters at the State University of Southwest Bahia Dentistry course. The data was collected via a questionnaire and authored by Solane Domingues Leal.
Jiwang Liang's retrospective study analyzes data from 599 papillary thyroid microcarcinoma patients who underwent surgery from 2005 to 2017 at a single institution. The dataset includes clinicopathologic factors and preoperative sonographic characteristics used to predict central lymph node metastasis, which had an incidence of 22.4%. A nomogram was developed based on identified risk factors to aid surgical decision-making.
A clinical study compares patients with suspected coronary microvascular dysfunction (CMD) related to Chagas disease against patients with CMD from other causes. The dataset likely contains clinical, hemodynamic, angiographic, and scintigraphic characteristics for 101 stable patients with angina and normal epicardial coronary arteries, including 15 with suspected CMD-CE. The research was published by Felipe Campos in Arquivos Brasileiros de Cardiologia in 2020.
