Global veganism campaigns like 'Veganuary' have gained popularity. We conducted an observational study to assess the impact of a 4-week vegan diet during 'Veganuary' on nutrient intake, status, knowledge, and motivations for veganism. Data were collected before and after 'Veganuary', using Food Frequency Questionnaires (FFQs) to estimate dietary intake. Micronutrient knowledge and motivation were assessed through questionnaires. A total of 154 UK adults aged 18-60 years (2019: n81; 2020: n73) participated. Groups were vegetarians and omnivores committed to a 4-week vegan diet during 'Veganuary'. Control groups were vegans and omnivores who did not transition. Short-term vegan diets significantly decreased intake of iodine, B12, cholesterol, and saturated fatty acids (SFAs) in omnivores. Micronutrient knowledge was low, and motivation for veganism varied. Short-term vegan diets reduce macro- and micronutrient intake in omnivores. Veganuary participants could benefit from nutritional guidance or supplementation. Attention is required for UK micronutrient intake and knowledge. Motivations for vegan pledges may influence diets, warranting further research.
There are 14 unconfounded randomised trials of antihypertensive drugs (chiefly diuretics or beta-blockers): total 37,000 individuals, mean treatment duration 5 years, mean diastolic blood pressure (DBP) difference 5-6 mm Hg. In prospective observational studies, a long-term difference of 5-6 mm Hg in usual DBP is associated with about 35-40% less stroke and 20-25% less coronary heart disease (CHD). For those dying in the trials, the DBP difference had persisted only 2-3 years, yet an overview showed that vascular mortality was significantly reduced (2p less than 0.0002); non-vascular mortality appeared unchanged. Stroke was reduced by 42% SD 6 (95% confidence interval 35-50%; 289 vs 484 events, 2p less than 0.0001), suggesting that virtually all the epidemiologically expected stroke reduction appears rapidly. CHD was reduced by 14% SD 5 (95% CI 4-22%; 671 vs 771 events, 2p less than 0.01), suggesting that just over half the epidemiologically expected CHD reduction appears rapidly. Although this significant CHD reduction could well be worthwhile, its size remains indefinite for most circumstances (though beta-blockers after myocardial infarction are of substantial benefit). At present, therefore, a sufficiently high risk of stroke (perhaps because of age, blood pressure, or, in particular, history of cerebrovascular disease) may be the clearest indication for antihypertensive treatment.

In a mountainous but extremely green landscape goats jump over the rocks and laughing children run after them. In this paradise on earth, nomadic families have found their temporary home. From one of these families comes a teenage girl, Shahnaz. The girl should be getting married soon, but her thoughts are focused on the world of literature.
As a child, trees provided a place of solace and safety to Nalini, so much so that she swore an oath to protect them. Now, Nalini is doing the work of untangling the roots of her past and bringing family secrets to light, in order to understand how each impacted her life's course. In an attempt to heal, she revisits the site of her fall on the Olympic Peninsula in Washington, where her past, present, and future converge.
Through a series of extraordinarily honest and intimate conversations, filmmaker Aurora Brachman examines the intergenerational fallout of experiences her mother endured as a child. Together, they forge a path forward that offers them a new beginning.

Although grizzly bear use of army cutworm moth (Euxoa auxiliaris) sites was documented in northwestern Montana in the mid-1950s, it was relatively unknown to scientists studying Yellowstone grizzly bears until the 1980s. There had been undocumented reports of grizzly bears eating "bugs," "insects," or "moths;" but it was not until 1986 that a radio-collared grizzly bear was observed feeding on moths in the GYE (French et al. 1994).
Army cutworm moths do not reside in the Absaroka Mountains year-round;in early summer, they migrate long distances to these alpine areas from the agricultural fields of the Great Plains. Once in the mountains, they feed on the nectar of alpine flowers by night and hide out in the interstitial spaces of the rocky talus slopes by day.These slopes are typically at or above 3,200 meters (10,500 feet) in elevation. It is on these high-elevation talus slopes that grizzly bears seek out army cutworm moths. By moving rocks and licking up the fast-moving moths before they can escape into another hole between rocks, bears can consume from 40,000 to 60,000 moths in a single day (White et al. 1999). At 8 kilocalories per gram, army cutworm moths are the richest documented food available to grizzly bears in the GYE (French et al. 1994). Remarkably, this level of moth consumption can supply a typical grizzly bear with approximately one-half of its annual caloric requirements in a 30-day period (White et al. 1999).
The abundance of moths, their high caloric value, and their ubiquitous dispersal within sites, make grizzly bears feeding at moth sites generally tolerant of other bears;they can be found feeding in groups of a dozen or more (French et al. 1994, Robison 2009). This is similar to bears feeding on the salmon streams of Alaska, where abundant food decreases the "personal space" requirements of bears (Smith et al. 2005). Because these talus slopes are generally remote from human development, foraging on moths keeps grizzly bears away from most human activities in summer, thereby reducing the potential for human-bear conflicts in these areas.
In agricultural areas in the Great Plains, army cutworm moths are considered an agricultural nuisance, and pesticides are used to control their numbers. Concerns have been raised about the potential for bioaccumulation of pesticides in bears feeding on moths. However, tests conducted on moths collected at moth aggregation sites where grizzly bears feed found little to no pesticide residue, likely due to moths amassing most of their summer body fat in the alpine tundra where pesticides are not used (Robison 2009).
