Consensus recommendations for measuring the impact of contraception on the menstrual cycle in contraceptive clinical trials.

Objective: We sought to develop consensus recommendations for measurement and analysis of data on contraceptive-induced menstrual changes (CIMCs) in contraceptive clinical trials. We built upon previous standardization efforts over the last 50 years and prioritized input from a variety of global experts and current regulatory authority guidance on patient-reported outcomes.

Study Design: We completed a formal consensus-building process with an interdisciplinary group of 57 experts from 30 organizations and 14 countries in five global regions who work across academia, nonprofit research organizations, the pharmaceutical industry, and funding agencies.

Examining the Impact of Diet-and-Exercise-Induced Weight Loss on Drug Metabolism and Gastric Emptying in Patients with Obesity.

Obesity significantly influences drug pharmacokinetics (PK), which challenges optimal dosing. This study examines the effects of diet-and-exercise-induced weight loss on key drug-metabolizing enzymes and gastric emptying in patients with obesity, who frequently require medications for comorbidities. Participants followed a structured weight management program promoting weight loss over 3-6 months and were not concomitantly on potential CYP inducers or inhibitors.

Management of a Muskellunge Fish Bite to the Thumb With Subsequent Flexor Tendon Laceration.

Despite frequent occurrences, especially throughout the Appalachian region, fish bite injuries remain largely underreported. Muskellunge anglers are at a particularly heightened risk due to the fish's large mouth and notably sharp teeth. We present a case of a male who sustained an injury to the right volar thumb following a muskellunge bite.

No Bridge between Us: EXAFS and Computations Confirm Two Distant Iron Ions Comprise the Active Site of Alkane Monooxygenase (AlkB).

Alkane monooxygenase (AlkB) is the dominant enzyme that catalyzes the oxidation of liquid alkanes in the environment. Two recent structural models derived from cryo-electron microscopy (cryo-EM) reveal an unusual active site: a histidine-rich center that binds two iron ions without a bridging ligand. To ensure that potential photoreduction and radiation damage are not responsible for the absence of a bridging ligand in the cryo-EM structures, spectroscopic methods are needed.

The impact of spillover and crossover effects of job stressors on pregnancy rates in couples undergoing in vitro fertilization treatments.

Purpose: Studies have shown mixed findings regarding the impact of stress on the success of fertility treatments. To the best of our knowledge, stress in the context of the workplace has not been investigated to date in relation to the success of fertility treatments. This research investigates the impact of work-related stress and emotional exhaustion experienced by both partners on in vitro fertilization (IVF) treatment outcomes.
