Analyzing Potential Non-Ignorable Selection Bias in an Off-Wave Mail Survey Implemented in a Long-Standing Panel Study.

Typical design-based methods for weighting probability samples rely on several assumptions, including the random selection of sampled units according to known probabilities of selection and ignorable unit nonresponse. If any of these assumptions are not met, weighting methods that account for the probabilities of selection, nonresponse, and calibration may not fully account for the potential selection bias in a given sample, which could produce misleading population estimates. This analysis investigates possible selection bias in the 2019 Health Survey Mailer (HSM), a sub-study of the longitudinal Health and Retirement Study (HRS).

From spasms to smiles: how facial recognition and tracking can quantify hemifacial spasm severity and predict treatment outcomes.

Purpose: Currently available grading and classification systems for hemifacial spasm either rely on subjective assessments or are excessively intricate. Here, we make use of facial recognition and facial tracking technologies towards accurately grouping patients according to severity and characteristics of the spasms.

Methods: A retrospective review of our prospectively maintained preoperative videos database for hemifacial spasm was done.

Electronically Monitored Antidepressant Adherence in Adolescents with Anxiety Disorders: A Pilot Study.

Antidepressant medication adherence patterns are inconsistent in adolescents with anxiety and related disorders, and the clinical and demographic features predicting adherence are poorly understood. In an ongoing single-site prospective trial involving adolescents (aged 12-17) with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition anxiety disorders treated with escitalopram, adherence was measured for 12 weeks using electronic monitoring caps. Adherence patterns were examined using qualitative and unsupervised clustering approaches, and predictors of adherence were evaluated using logistic regression, with demographic (age, sex, and race) and clinical variables (e.

Early detection and progression of insulin resistance revealed by impaired organismal anti-inflammatory heat shock response during ex vivo whole-blood heat challenge.

Chronic inflammatory diseases, e.g., obesity, cardiovascular disease and type-2 diabetes, progressively suppress the anti-inflammatory heat shock response (HSR) by impairing the synthesis of key components, perpetuating inflammation.

Colloid cyst of the third ventricle: a rare case of spontaneous regression. Illustrative case.

Background: Colloid cysts (CCs) are benign lesions commonly located in the third ventricle, near the foramen of Monro. They constitute about 0.5%-1% of all intracranial tumors.
