Pattern of psychotropic medications use in a cohort of patients with uninvestigated dyspepsia undergoing upper endoscopy: A retrospective study

Exercise is inversely associated with functional dyspepsia among a sample of Chinese male armed police recruits

BACKGROUND

There is no study evaluating the association between exercise and functional dyspepsia (FD) based on the Rome IV criteria. We aimed to investigate the prevalence of FD and evaluate the association between exercise and FD based on Rome IV criteria among a sample of Chinese armed police recruits.

METHODS

An on-site questionnaire survey on FD among a sample of Chinese armed police recruits was conducted based on the Rome IV criteria in 2021. Potential confounders included age, body mass index (BMI), race, marriage, education, smoking, and drinking variables were adjusted.

RESULTS

A total of 2594 recruits were enrolled, including 46 FD participants and 2548 non-FD participants. In the model adjusted for all demographic variables among participants excluding irritable bowel syndrome (IBS) and functional constipation (FC), compared with no exercise participants, 1 h < each exercise time ≤ 2 h (OR = 0.15, 95% CI: 0.03-0.77, P = 0.0230) was inversely associated with FD and compared with no exercise participants, mild exercise (OR = 0.09, 95% CI: 0.01-0.71, P = 0.0220) was significantly inversely associated with FD.

CONCLUSIONS

The incidence rate of FD in this sample Chinese armed police recruits was 1.77%, and 1 h < each exercise time ≤ 2 h and mild intensity exercise were independently inversely associated with FD. However, the causal relationship needs to be verified by further randomized controlled trials.

Gender Differences in Function, Physical Activity, Falls, Medication Use, and Life Satisfaction Among Residents in Assisted Living Settings

The purpose of the current study was to test for gender differences among residents living in assisted living settings. This was a secondary data analysis using data from the first 64 facilities participating in the ongoing Function Focused Care for Assisted Living study using the Evidence Integration Triangle (FFC-AL-EIT). A total of 593 residents were recruited. Differences by gender with regard to function, physical activity, falls, total number of medications, and satisfaction with assisted living were tested using multivariate analysis of variance. There were 166 (28%) men and 427 (72%) women with a mean age of 88 (SD = 7.5 years). Participants had five (SD = 2) comorbidities and took on average 6.88 medications (SD = 3.47). Participants had moderate functional impairment with a mean of 64.13 (SD = 19.09) on the Barthel Index and engaged in 43.8 (SD = 76.12) minutes daily of moderate level physical activity. Women reported higher satisfaction with activities (4.32 [SD = 1.14]) than men (3.85 [SD = 1.51]), and women received more medications than men (7.09 [SD = 3.51] vs. 6.34 [SD = 3.31]). Current study findings suggest that deprescribing may be particularly important for women versus men and focusing on expanding activity options to include those preferred by men should be considered in assisted living settings.

The association of adult height with the risk of cardiovascular disease and cancer in the population of Sardinia

The relationship between body height and the risk of non‒communicable diseases such as cardiovascular disease and cancer has been the subject of much debate in the epidemiological literature. Concerns have recently arisen over spurious associations due to confounding factors like birth cohort, especially in the context of epidemiological transition. The population of Sardinia represents an interesting case study, as the average physical stature of inhabitants was the lowest recorded in Europe until a few decades ago. In this population we tested whether height is an independent risk factor for cardiovascular disease and cancer. We analysed the stature of 10,427 patients undergoing endoscopy for any reason, for whom a detailed clinical history of cardiovascular disease and/or malignancies had been documented. Poisson regression modelling was used to test the association between stature and disease risk. When patients were subdivided according to sex and height tertiles, the risk of cardiovascular disease proved significantly greater for subjects in the lowest tertile irrespective of sex (men: 1.87; 95%CI 1.41‒2.47; women: 1.23; 95%CI 0.92‒1.66) and smaller for those in the highest tertile (men: 0.51; 95%CI 0.35‒0.75; women: 0.41; 95%CI 0.27‒0.61). However, after adjusting the risk for birth cohort and established risk factors, it mostly resulted in non-significant values, although the overall trend persisted. Similar results were obtained for all-cancer risk (relative risk for men and women in the lowest tertile: 1.44; 95%CI 1.09–1.90 and 1.17; 95%CI 0.93–1.48, in the highest tertile: 0.51; 95%CI 0.36–0.72 and 0.62; 95%CI 0.47–0.81, respectively) as well as for some of the most common types of cancer. We concluded that the risk of developing cardiovascular disease and malignancies does not vary significantly with stature in the Sardinian population, after adjusting for birth cohort and more obvious risk factors.

Updates on the biology of serotonin and tryptophan hydroxylase

PURPOSE OF REVIEW

To summarize the most recent findings relevant to the biology of serotonin (5-hydroxytryptamine; 5-HT) and the enzyme tryptophan hydroxylase (TPH) in human gastrointestinal disease.

RECENT FINDINGS

Serotonin is synthesized in the central nervous system (CNS) and the gastrointestinal tract where it is secreted from enteroendocrine cells. Its biosynthesis is regulated by two isoforms of the enzyme TPH of which TPH1 is localized predominantly in gastrointestinal enteroendocrine cells. Serotonin activates the peristaltic reflexes, regulates gastrointestinal motility, and has a role in intestinal inflammation. Inhibition of TPH with novel molecules represents a new pharmacological tool in the successful management of carcinoid syndrome in patients with gastrointestinal neuroendocrine tumors (GI-NETs). Certain 5-HT receptor subtype agonists and antagonists are useful in the treatment of functional gastrointestinal disorders.

SUMMARY

The gastrointestinal tract is the largest storage organ for serotonin where its biosynthesis is regulated by TPH1. It has several important functions in gastrointestinal motility, secretion, and inflammation. Furthermore, TPH represents a target for inhibitory pharmacological therapy of serotonin access states such as the carcinoid syndrome.
