A recent study conducted by The University of Hong Kong (HKU) revealed that long-term use of proton pump inhibitors (PPIs) is associated with a significantly increased risk of gastric cancer even in patients who have had Helicobacter pylori eradicated.

Men with breast cancer have tumours that are typically of the human epidermal growth factor receptor 2-negative Luminal B subtype and positive for oestrogen receptor, progesterone receptor and androgen receptor, according to the results of the EORTC 10085/TBCRC/BIG/NABCG International Male Breast Cancer Program study.

Men more sensitive to blue light

The cornea, the transparent outermost layer of the eye, protects the eye from infection and physical injury.

Sensitivity to blue-enriched light is influenced by sex differences, such that males display a stronger response even to very low light levels, a recent study suggests. Moreover, sex differences also affect the acute benefits of bedtime blue light exposure such as sustained attention.

In the study, 32 participants (mean age 25.2±3.1 years; 50 percent female) were subjected to 1.5 hours of dim light (<8 lx), 2 hours of darkness, 2 hours of light exposure (40 lx) and 45 minutes of dim light (<8 lx), in sequence, until habitual sleep time. Both groups were matched according to age, ethnicity and body mass index.

Males preferred the 40-lx light delivered by a 6,500-K than by a 2,500-K fluorescent lamp (62.5 vs 37.5 percent). An opposite trend was observed for females (12.5 vs 87.5 percent, respectively), with the difference between the sexes reaching significance (p=0.004).

In a posthoc analysis, males were found to perceive the 6,500-K light as significantly stronger than the 2,500-K light (mean, 85.6±4.5 vs 67.7±5.4).

Light condition, specifically the 6,500-K light, significantly improved the median response time (p<0.005) and 10-percent fastest response time (p<0.001) exclusively in males. No such effect was observed in females.

Moreover, following exposure to 6,500-K light before bedtime, males had significantly higher frontal nonrapid eye movement slow-wave activity (2 to 4 Hz) sleep electroencephalogram power density than women (p<0.05).

“Collectively, the data indicate that sex differences in light sensitivity might play a key role for ensuring the success of individually-targeted light interventions,” said researchers.
