Uncovering the evolution of Hezbollah’s political communication strategy

A study by Ritsumeikan University found that Hezbollah's political communication is shaped by institutional constraints and strategic considerations in Lebanon's consociational democracy. The party adopted a more critical stance during crises but became more cooperative with rivals after diplomatic relations were restored.

Opioid prescribing standards changed practices in BC, but with caveats

The introduction of BC's opioid prescribing standard in 2016 led to a reduction in opioid prescriptions and doses, as well as declines in high-dose prescribing and coprescribing with benzodiazepines. However, this change also resulted in increased aggressive tapering of medications, which can lead to improper pain management.

3-month program of time-restricted eating at any time of the day supports long-term weight loss in adults with overweight or obesity

Researchers found that a 3-month program of time-restricted eating at any time of the day can result in significant weight loss for at least a year, regardless of eating window timing. The study suggests that restricting the eating window to 8 hours may be an effective long-term approach for sustaining weight loss.
