Comparison of Methods for Sensitivity Analysis of Heterogeneous Treatment Effects in Observational Studies and Application to Alzheimer's Disease and Cognitive Decline

Statistics in Medicine, Volume 45, Issue 6-7, March 2026.
ABSTRACT In Alzheimer's disease (AD) research, many observational studies have shown that the effect of sleeping quality, a modifiable risk factor, on cognitive decline is heterogeneous, where some adults experience faster rates of cognitive decline compared to others.

Ovarian influence on circadian and infradian modulation of nicotine‐seeking in female mice

Journal of Neuroendocrinology, Volume 38, Issue 3, March 2026.
Abstract Sex differences in tobacco intake are closely associated with hormonal fluctuations during the menstrual cycle in women. Elevated estrogen levels have been associated with increased stress, which may lead to a higher likelihood of seeking psychoactive substances.

Flying Airplanes: Realizing Circadian Effects (FARCE) [PDF]

People differ in their diurnal (time-of-day) preferences—some are morning-types and others are evening-types. These differences are explored in a unique experiment design in which subjects are randomly assigned to produce paper airplanes at either 8:00 a.

Empowered or Overwhelmed? Wearable Health Technologies and Consumer Well‐Being in the Context of Consumer–Physician Interactions

Journal of Consumer Affairs, Volume 60, Issue 1, Spring 2026.
ABSTRACT Wearable health technologies (WHTs) increasingly enable continuous, consumer‐driven health monitoring, yet healthcare systems remain organized around episodic, reactive care. This research examines how this misalignment shapes consumer well‐being by integrating consumer and physician perspectives on wearable‐generated data.

Causal Associations Between Sleep Traits and Polycystic Ovary Syndrome: A Univariable, Bidirectional, and Multivariable Mendelian Randomization Study

Journal of Obstetrics and Gynaecology Research, Volume 52, Issue 3, March 2026.
ABSTRACT Background Observational studies have reported associations between various sleep traits and polycystic ovary syndrome (PCOS); however, it remains unclear whether these relationships are causal or driven by confounding factors. This study aimed to clarify the direction and magnitude of potential causal effects between eight self‐reported sleep

Can Morning Light Phase Advance Human Melatonin Rhythms in Less Than 24 h?

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Light is the primary cue that synchronises the human circadian system to the 24‐h day, advancing or delaying circadian rhythms depending on its timing. While it is known that morning light induces phase advances, most studies assess the timing of dim‐light melatonin onset (DLMO) in the subsequent circadian cycle, over 24 h after the light ...

Low‐Dose Melatonin, Climacteric Symptoms and Sleep in Female Shift Workers: A Randomized Controlled Trial

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Sleep disturbances and mood changes are common during the climacteric, often linked to hormonal fluctuations caused by reduced ovarian function. Evidence suggests that long‐term melatonin administration may improve the quality of life in climacteric women. This study aimed to evaluate the effects of exogenous melatonin on climacteric symptoms,
