Purpose: Perceived cancer-related cognitive impairment (CRCI) has been reported in prostate cancer survivors. Little is known about how CRCI impacts occupational functioning in working-aged prostate cancer survivors (PCS). This study aimed to investigate the association between CRCI and occupational functioning in PCS.

These interoceptive cues may have psychological consequences, namely an ability to enhance the desire to eat, which are independent of their physiological cause. Testing this idea is difficult because the physiological processes are normally linked to any consequence.

- High-power tunable lasers are highly sought after for their applications in telecom, ranging, and molecular sensing, but integrated photonics has struggled with power due to size limitations.
- The introduction of large-mode-area (LMA) fibers in the late 90s significantly improved the power capability of fiber systems by increasing the optical mode area.
- This study demonstrates a silicon photonics-based LMA power amplifier that achieves an output power of 1.8W over a 60nm tunability range, indicating a potential advancement in integrated lasers for high-power applications that can compete with traditional bench systems.
Research on nutraceutical and dietary interventions in psychiatry has grown substantially, but progress is hindered by methodological inconsistencies and limited reporting standards. To address this, the International Society for Nutritional Psychiatry Research presents the first guidelines on clinical trial design, conduct, and reporting for future clinical trials in this area. Recommendations were developed using a Delphi process including eighteen researchers with considerable clinical trial expertise and experience in either methodology, nutraceutical, or dietary interventions in psychiatry.

- Previous research found that lead (Pb) and other heavy metals are present in eggs from backyard birds, with environmental exposure likely playing a key role in this contamination.
- A cohort study measured Pb levels in eggs and various tissues, finding much higher concentrations in bone, blood, and liver compared to eggs.
- The low Pb concentration in eggs suggests that while chickens may accumulate Pb in other tissues, this still poses a public health risk due to potential exposure through consumption.
