Previous reports have suggested a possible role for vitamin D in the etiology of chronic spontaneous urticaria (CSU); however, little information is available regarding the role of other micronutrients. We, therefore, analyzed vitamin D, vitamin B12, and ferritin levels in CSU patients (n = 282) from a preexisting database at Southampton General Hospital. Data were compared against mean micronutrient levels of the general population of the UK, obtained from the National Diet and Nutrition Survey. Vitamin D levels of CSU patients were found to be higher than those of the general UK population (P = 0.001). B12 levels were lower in patients with CSU (P < 0.001) than in the general population. Ferritin levels were found to be lower in male CSU patients than in the general male population (P = 0.009). This association between low B12 and iron levels and CSU might indicate a causal link, with micronutrient replacement as a potential therapeutic option.

Acute pancreatitis (AP) is a serious inflammatory disease with high incidence rate and mortality. It was confirmed that overactivation of autophagy in acinar cells can increase the risk of AP. Nevertheless, the regulatory mechanism of autophagy in AP is unclear.

Obstructive sleep apnea (OSA) patients have varying degrees of cognitive impairment, but the specific pathogenic mechanism is still unclear. Meanwhile, poor compliance with continuous positive airway pressure (CPAP) in OSA prompts better solutions. This study aimed to identify differentially expressed genes between the non-obese OSA patients and healthy controls, and to explore potential biomarkers associated with cognitive impairment.

Sleep deficiency is associated with obesity, but the mechanisms underlying this connection remain unclear. Here, we identify a sleep-inducible hypothalamic protein hormone in humans and mice that suppresses obesity. This hormone is cleaved from reticulocalbin-2 (RCN2), and we name it Raptin.

Background: In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.
Objectives: The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.
Methods: This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines.

This study examined the link among environmentally conscious organizational citizenship behavior (OCBE) and responsible leadership among 167 management-level workers in manufacturing plants of arts industry in a developing economy. The study explored the impact of responsible leadership on OCBE, both directly and indirectly through colleague exchange. It also explored the role of a green organizational environment, employee goal orientation, and supervisory support in regulating the link between coworker exchange and OCBE.
