Does medullary diameter to stem width ratio and stem length affect outcomes of revision total knee arthroplasties? A case series.

Objectives: This study aimed to investigate the relationship between the ratio of stem size to intramedullary canal diameter, stem length, and functional outcome in revision total knee arthroplasty (RTKA) procedures, which remains largely unexplored in the current literature.

Patients And Methods: A single surgeon series of RTKA procedures performed between October 2014 and November 2022 were included in this case series, and data were analyzed retrospectively. A total of 32 patients (27 females, 5 males; mean age: 73.

Acute transverse myelitis after inactivated COVID-19 vaccine.

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration.

Association between serotonin 2A receptor (HTR2A), serotonin transporter (SLC6A4) and brain-derived neurotrophic factor (BDNF) gene polymorphisms and citalopram/sertraline induced sexual dysfunction in MDD patients.

Sexual dysfunction (SD) is a troublesome adverse effect of selective serotonin reuptake inhibitors (SSRIs). A variety of mechanisms might be involved in the occurrence of SD but the exact mechanism is still not clear. Genetic variations among patients treated with SSRIs are strong determinants of intolerance and poor compliance.

Interplay of Homogeneous Reactions, Mass Transport, and Kinetics in Determining Selectivity of the Reduction of CO on Gold Electrodes.

Gold electrocatalysts have been a research focus due to their ability to reduce CO into CO, a feedstock for further conversion. Many methods have been employed to modulate CO reduction (CDR) vs hydrogen evolution reaction (HER) selectivity on gold electrodes such as nano-/mesostructuring and crystal faceting control. Herein we show that gold surfaces with very different morphologies (planar, leaves, and wires) lead to similar bell-shaped CO faradaic efficiency as a function of applied potential.
