A single-center retrospective study of 93 major depressive disorder patients (53 treatment-resistant, 40 non-treatment-resistant).

Fifteen studies involving 2,397 patients were included in this systematic review and meta-analysis by Kexuan Zhu, evaluating Enhanced Recovery After Surgery (ERAS) protocols for elderly patients undergoing major abdominal surgery. The analysis, last updated in May 2026, found ERAS significantly reduced hospital stay and complication rates compared to conventional care. The underlying data supporting the meta-analysis is provided as a supplementary document.
A retrospective medical record review of patients diagnosed with acquired external auditory canal stenosis (EACS) treated at The Second Xiangya Hospital between November 2020 and November 2025. The dataset includes variables such as age, gender, etiology, clinical symptoms, surgical methods, and postoperative outcomes. The study found a 57% postoperative recurrence rate in pediatric patients, significantly higher than the 25% rate observed in adults.
A prospective study at an 1800-bed tertiary-care hospital in India from March 2023 to March 2024 evaluated a structured urine-culture request form. The dataset includes 484 patients split between a test arm using the structured form and a control arm using routine forms, tracking outcomes like treatment of asymptomatic bacteriuria and guideline-concordant prescribing. The research was authored by Supreeta R Shettar and shared under a CC-BY-4.0 license.
A 2026 meta-analysis by Shu-Hong Ching synthesizes data from 16 randomized controlled trials (RCTs) sourced from PubMed, Web of Science, and other databases. It evaluates the short-term efficacy and safety of micro-osteoperforation (MOPs) as an adjunct to orthodontic treatment. The analysis includes 1,175 screened records and reports quantitative outcomes on tooth movement acceleration and adverse effects.
A dataset of 435 patients (174 with MAFLD, 261 with MAFLD and CHD) was used to evaluate coronary inflammation and insulin resistance. The data includes AI-calculated pericoronary fat attenuation index (FAI) and triglyceride-glucose (TyG) index, CT-derived fractional flow reserve (CT-FFR), and other clinical variables. The study, authored by Xiaolong Bai and last updated in May 2026, constructed a predictive nomogram for coronary heart disease and functional ischemia.
Shengjie Wu published a meta-analysis on 2026-05-21 exploring the prognostic value of the Prognostic Nutritional Index (PNI) for patients with non-small cell lung cancer undergoing curative surgery. The analysis includes 11 studies searched from PubMed, Embase, Web of Science, and Cochrane up to October 2025. It calculates pooled hazard ratios for overall, recurrence-free, and cancer-specific survival.
Ning Li's systematic review and meta-analysis, last updated in May 2026, aggregates findings from 19 studies involving over 3,900 patients. The document synthesizes evidence on cardiac magnetic resonance biomarkers like extracellular volume fraction and myocardial perfusion reserve for detecting subclinical myocardial changes in diabetes. The analysis suggests these biomarkers provide insights into myocardial involvement but notes the need for more prospective trials.
117 breast cancer patients who developed brain metastases from 2008 to 2023 were analyzed for changes in peripheral blood monocyte counts. The absolute monocyte count increased 2.11-fold at brain metastasis diagnosis, and a high lymphocyte-to-monocyte ratio was associated with a median survival of 20.0 months versus 5.13 months in the low group. This dataset, authored by Jihwan Yoo and shared under CC-BY-4.0, suggests monocyte dynamics may serve as exploratory prognostic markers.
Yukon cancer surveillance reports provide a detailed summary of cancer incidence among residents. The reports examine cancer types, distribution by sex, age at diagnosis, and stage at diagnosis. Data originates from the population-based Yukon Cancer Registry.
December 2022 to July 2024 clinical data from 372 adult patients who underwent laparoscopic colorectal surgery at the Third Xiangya Hospital of Central South University. Collected by Yu, Rili and hosted on Harvard Dataverse, it investigates the association between preoperative serum indirect bilirubin levels and chronic postsurgical pain at 3 months postoperatively.
Maisa Bastos Moroz authored a cross-sectional study analyzing blood pressure control in 190 hypertensive elderly women from a Family Health Unit. The dataset likely contains patient records with factors like age and residence distance, used to calculate prevalence ratios and conduct logistic regression. 108 patients (56.8%) had controlled blood pressure, defined as lower than 140/90mmHg.
2573 patients were enrolled across five randomized controlled trials comparing implantable cardioverter-defibrillator (ICD) therapy plus medical treatment to medical treatment alone for non-ischemic heart failure. The meta-analysis, authored by Zhenhua Xing, derived pooled risk ratios from PubMed, Embase, and Cochrane Central databases. It found ICD therapy combined with medical treatment was associated with a significantly lower risk for all-cause mortality (Risk ratio: 0.83; 95% CI 0.71 to 0.97).
A dataset from Clalit Health Services contains 611,993 chalazion diagnoses across 412,365 patients, recorded between January 2003 and December 2022. It was created by Yogev Giladi for a retrospective cohort study analyzing demographic data, medical history, treatments, procedures, and outcomes. The study found invasive procedures were required in 9.3% of cases and incidence correlated strongly with mean monthly temperature.
128 pregnant individuals diagnosed with intrahepatic cholestasis of pregnancy (ICP) and matched healthy controls were recruited for a prospective cohort study. Bile acid profiles were quantified using liquid chromatography-tandem mass spectrometry to develop a predictive nomogram model. The model demonstrated excellent discrimination, with an AUC of 0.920 in the training cohort and 0.940 in the validation cohort.
A prospective observational pilot study from January to June 2025 includes data from 27 patients with stable chronic obstructive pulmonary disease (COPD) and 10 healthy controls. The dataset, authored by Wei Sun and shared under a CC-BY-4.0 license, contains flow cytometry results for eosinophil subtypes, pulmonary function tests, and cytokine levels. It was last updated on May 25, 2026.
A retrospective cohort study of 5,650 critically ill patients with acute myocardial infarction from the MIMIC-IV v3.1 database. The research, authored by Guibao Jiang and last updated in May 2026, analyzes the association between intravenous magnesium sulfate administration and ICU mortality using multivariable Cox regression and propensity score matching. It identifies a 45% reduction in mortality risk and explores dose-response relationships.
A prospective cohort study of 103 patients with generalized myasthenia gravis (gMG) who received efgartigimod, focusing on 18 patients with an inadequate early response who were subsequently treated with eculizumab. Clinical outcomes were assessed using MG-ADL and QMG scores, with data collected by Xueting An and last updated in May 2026. The dataset likely contains patient-level clinical scores and treatment response metrics.
A single-center observational study includes 66 maintenance hemodialysis patients categorized into Normal, Pre-Frailty, and Frailty groups.

It was authored by Hongmei Liu and last updated on May 25, 2026.
669 patients initially diagnosed with positive thyroid autoantibodies in Nanjing from January 2018 to December 2024 were enrolled in this multicenter retrospective cohort study. During a median follow-up of 3.0 years, 155 patients progressed to overt or subclinical hypothyroidism. The dataset, authored by Xue Feng and shared under a CC-BY-4.0 license, contains baseline demographic data, thyroid function parameters, and autoantibody levels used to identify independent risk factors.
