Association of Tramadol Versus Codeine Prescriptions with all-cause mortality and cardiovascular diseases among patients with osteoarthritis: a systematic review and meta-analysis of propensity score-matched population-based cohort studies.

Background: Today, the prescription of tramadol in patients with osteoarthritis (OA) has increased significantly, which can be associated with serious consequences. Contradictory results have been reported regarding the association of tramadol versus codeine with the risk of all-cause mortality (ACM) and cardiovascular diseases (CVD).

Methods: This systematic review and meta-analysis aimed to evaluate, for the first time, the association of tramadol versus codeine with the risk of ACM and CVD in OA patients for the first time.

Computer-Aided Classification of Breast Lesions Based on US RF Time Series Using a Novel Machine Learning Approach.

Objectives: One of the most promising adjuncts for screening breast cancer is ultrasound (US) radio-frequency (RF) time series. It has the superiority of not requiring any supplementary equipment over other methods. This research aimed to propound a machine learning (ML) approach for automatically classifying benign, probably benign, suspicious, and malignant breast lesions based on the features extracted from the accumulated US RF time series.

Stroke in supplementary motor area mimicking functional disorder: a case report.

Supplementary motor area, the posterior third of the medial aspect of superior frontal gyrus, is known to be a heterogeneous area in function. It is involved in self-initiated motor movements, planning and sequencing the motor action, response inhibition, and bimanual movements. Blood supply for supplementary motor area is mostly by callosomarginal branch of anterior cerebral artery.

Metabolic Syndrome and the Iodine-Dose/Creatinine Clearance Ratio as Determinants of Contrast-Induced Acute Kidney Injury.

Background: Finding patients at risk of developing contrast-induced acute kidney injury (CI-AKI) is important because of its associated complications. In the present study, the contribution of different variables, such as the presence of metabolic syndrome (MetS), the volume creatinine clearance (V/CrCl) ratio, the iodine-dose (I-dose)/CrCl ratio, or hypertension, to CI-AKI was evaluated.

Methods: A total of 255 patients undergoing elective coronary angiography with or without intervention were enrolled and divided into a MetS and a control group.
