A new population pharmacokinetic model for dosing optimization of zonisamide in patients with refractory epilepsy.

Zonisamide exhibits significant pharmacokinetic variability, demanding for the development of population pharmacokinetic (PopPK) models to identify key factors influencing drug disposition. This study aimed to develop and validate a PopPK to optimize zonisamide posology in patients with refractory epilepsy. A total of 114 plasma concentrations of zonisamide, obtained from 64 patients, were used for PopPK model development, employing the nonlinear mixed-effects modelling approach.

Impact of Expanded Eligibility for Veterans With Other Than Honorable Discharges on Treatment Courts and VA Mental Health Care.

Background: US Department of Veterans Affairs (VA) eligibility policies now allow comprehensive mental and behavioral health care services to be provided to veterans who received an Other Than Honorable (OTH) discharge upon separation from service. Research has shown a disproportionate mental health burden and elevated rates of criminal-legal involvement among these veterans. Eligibility policy shifts may impact programs and services designed to support veterans with criminal-legal involvement, such as veterans treatment courts.

Prevalence of anhedonia in women with deep endometriosis.

Anhedonia, characterized by diminished motivation and pleasure sensitivity, is increasingly recognized as prevalent among patients with chronic pain. Deep Endometriosis (DE), the most severe endophenotype of the disease, is commonly presented with chronic pelvic pain. This cross-sectional study reports, for the first time, the prevalence of anhedonia in a sample comprised by 212 premenopausal women with suspected DE referred to a tertiary hospital.

Cervical lower motor neuron syndromes: A diagnostic challenge.

Cervical lower motor neuron (LMN) syndromes, also known as brachial paresis, are characterized by muscle atrophy, weakness, and decreased reflexes in the upper limbs, devoid of sensory symptoms. These syndromes can stem from various factors, including degenerative conditions, immune-mediated diseases, infections, toxic exposures, metabolic disorders, and vascular anomalies. Clinical presentations vary, with motor neuron involvement potentially limited to the cervical area or extending to other regions, affecting prognosis.
