38 patients completed a series of randomized, double-blind n-of-1 trials assessing on-demand sildenafil for Raynaud phenomenon. The dataset captures repeated crossover treatment blocks comparing placebo, 40 mg, and 80 mg sildenafil doses. Individual and aggregated efficacy was analyzed using mixed-effects models in a Bayesian framework.
Encompassing mass spectrometry proteomic data from cerebrospinal fluid samples of Alzheimer's disease patients and non-demented controls. It was generated by Payam Emami Khoonsari in 2020 using label-free shotgun mass spectrometry and processed with five analysis programs. The study identified eight proteins with significantly lower levels in Alzheimer's disease patients.
Municipal health care institutions in Poltava, Ukraine, maintain this list of medical equipment according to their fixed asset inventory descriptions. The dataset was last updated on August 11, 2020, and originates from the State site of Ukraine. It is provided in an Excel XLSX format.
The dataset describes the organizational structure of the CP '3rd City Clinical Hospital of PMR' in Ukraine. It was published on the States site of Ukraine and last updated on August 11, 2020. The information is structured according to the organizational and administrative document 'Structure and staffing'.
Encompassing paired, repeated measurements of coronary physiology metrics from 763 subjects enrolled from 12 international centers. It compares the diagnostic performance of contrast-based FFR (cFFR), resting distal pressure/aortic pressure (Pd/Pa), and the instantaneous wave-free ratio (iFR) against adenosine-derived fractional flow reserve (FFR).
A multicentre longitudinal cohort of 411 Parkinson's disease patients with ≤5 years disease duration at baseline, followed annually for up to 5 years. The study investigates the dose-effect relationship between dopamine replacement therapy and impulse control disorders, reporting a 5-year cumulative ICD incidence of 46.1%.
308 depth stacks of human skin from 54 volunteers in two age groups (20–30 and 50–70 years) were used to develop an automated segmentation model. The dataset supports classification of en-face sections into four anatomical strata: stratum corneum, viable epidermis, dermal-epidermal junction, and papillary dermis. The developed logistic regression classifier achieved 85.6% test accuracy.
An observational study of 87 ZIKV-infected patients with neurological manifestations during the 2016 French West Indies outbreak. The data characterizes the spectrum and prognosis of NeuroZika, with clinical follow-up available for 76 patients over a median of 14 months. It includes outcomes such as residual disability rates and mortality.
A nationwide retrospective cohort study from Taiwan's National Health Insurance Database includes 9,468 patients with primary Sjogren's syndrome (pSS) and 37,872 matched controls. The data, covering over 97% of Taiwan's population from 2002 to 2012, was used to analyze the risk of acute pancreatitis, with 44 cases identified in the pSS cohort versus 105 in controls. The study found a significantly higher incidence rate of acute pancreatitis in the pSS cohort, with specific hazard ratios calculated for medication effects.
A retrospective analysis of 222 patients with a first demyelinating event, assessing the prognostic value of serum neurofilament light chains (Nfls) for conversion to multiple sclerosis. The study includes baseline serum Nfls, CSF, MRI, and clinical data, with a mean patient follow-up of 100.6 months. It finds serum Nfls levels are prognostic for both Clinically Defined Multiple Sclerosis and McDonald 2017 MS.
2002-2014 data from 1,607 consecutive ischemic stroke patients in the Oxford Vascular Study, a population-based prospective cohort. The dataset relates 3-month modified Rankin Scale (mRS) scores to 1-year and 5-year disability, mortality, and health/social-care costs, with analysis of trial ineligibility based on pre-morbid mRS.
47% of vanA-positive Enterococcus faecium sterile site isolates were vancomycin-variable. The study prospectively collected isolates from Toronto hospitals between January 2015 and June 2016, reviewing patient charts for 36 VRE, 25 VVE, and 79 VSE bacteremia cases. Clinical characteristics like Pitt bacteremia and Charlson scores were analyzed as mortality predictors.
159 patient records from a retrospective review of extrapulmonary small cell carcinoma outcomes. The data includes stage at presentation, treatments, sites of relapse, and survival metrics. It originates from two major cancer centers.
A 2020 randomized controlled trial from a Brisbane tertiary hospital evaluated a pharmacist-led prescribing model against usual care for 400 elective surgery patients. The dataset contains results comparing the frequency and clinical significance of medication omissions and prescribing errors between the two groups. Secondary outcomes include the appropriateness of venous thromboembolism (VTE) prophylaxis prescribing.
275 adolescents with major depression were randomized to paroxetine, imipramine, or placebo across 12 North American centers from 1994 to 1998. This reanalysis under the RIAT initiative found no statistically significant efficacy for either drug compared to placebo and noted increases in specific harms. The dataset provides primary clinical trial data for re-evaluating evidence-based medicine conclusions.
Encompassing magnetic resonance diffusion kurtosis imaging (DKI) parameters for 124 breast lesions from 103 patients. It includes measured values for mean diffusivity (MD) and mean kurtosis (MK) to characterize benign and malignant tumors. The data was used to assess the diagnostic sensitivity and specificity of these DKI parameters.
Featuring audio and flow signal recordings from 20 healthy participants performing 15 inhalations each through a placebo dry powder inhaler. It was created to develop a method for estimating inhalation flow profiles using a single calibration audio recording. The study found power law regression models achieved an average flow estimation accuracy of 90.89%.
2706 patients with chronic obstructive pulmonary disease (COPD) or primary lung cancer (PLC) from three Shanghai hospitals were studied. The retrospective analysis quantified inappropriate tumor marker (TM) requests, finding 58.27–79.06% of 12,496–16,956 requests were unsuitable, costing 650,200–1,014,156 yuan. The dataset supports analysis of TM overuse, associated costs, and guideline adherence in pulmonary care.
A 2020 international survey collected 728 responses from referring physicians in 28 countries on radiation exposure knowledge and practices. The dataset captures physician opinions on patient dose tracking, self-assessment of referral appropriateness, and knowledge of radiation dose equivalencies. It was conducted via a web-based questionnaire by author Madan M. Rehani.
