Benefits and Drawbacks of International Medical Elective Databases in Abroad Elective Research: A Narrative Review.

Background: International medical electives (IMEs) are considered high-impact practice in global health education. Nevertheless, international medical elective (IME) research remains scarce, with only a few new publications appearing each year. The discrepancy between the many unanswered questions regarding IMEs and the lack of opportunities to perform research in this field has been further aggravated by the COVID-19 pandemic.

Nutrient Intakes in Prostate Cancer Survivors in the United States: A Nationally Representative Study.

There are currently more than 3.3 million prostate cancer (PC) survivors in the United States. Conformance with national dietary guidelines and a good diet quality may lower the risk for Gleason grade progression in PC patients.

Diet quality in U.S. adults eating in senior and community centers: NHANES 2009-2018.

Background: With advancing age, the worsening of cognitive and physical disabilities may lead older adults to seek help in their daily living activities. Community/senior centers support older adults during aging, offering a wide variety of services, including meal programs. Using data from the National Health and Nutrition Examination Surveys (2009-2018), we aimed to examine whether community/senior center meal programs were associated with an improved nutritional exposure in U.

Status of animal experimentation in nutrition and dietetic research: Policies of 100 leading journals and new approach methodologies.

Given animal research is challenged with inadequacies, e.g., animal-to-human knowledge translation, ethical considerations, and cost:benefit, new approach methodologies (NAMs) have been proposed as a replacement.

Vitamin B Status and Supplementation in Plant-Based Diets.

Plant-based diets are increasingly popular worldwide. A well-planned plant-based diet lowers the risk of cardiovascular disease, type 2 diabetes and certain cancers. In contrast, a poorly planned plant-based diet increases the risk of certain micronutrient deficiencies, chiefly, vitamin B (B).

Impact of vitamin B12 supplement intake cessation on vitamin B12 status in a healthy vegan: A close interval monitoring case study.

Background: Healthy plant-based diets, such as the lacto-ovo-vegetarian and the vegan diet, offer numerous benefits to human health. Poorly designed plant-based diets, however, bear the risk for vitamin- and micronutrient deficiencies. Vitamin B12 (B12, cobalamin) is a nutrient of particular concern in both diets, and should be readily supplemented on a continuous basis to ensure adequate B12 levels and to prevent deficiencies.

Citrate-based dietary alkali supplements available in Germany: an overview.

Background: Fruits and vegetables are abundant in alkali precursors and effectively reduce the Potential Renal Acid Load (PRAL) from diet. Oral alkali supplements are supposed to exert comparable alkalizing effects on the human body, and have been shown to beneficially affect bone and kidney health. A comparative analysis of the available dietary alkali supplements in Germany was performed, contrasting their potential PRAL-lowering potential.

The potential renal acid load of plant-based meat alternatives.

Plant-based meat alternatives (PBMAs) are food products derived from plants and designed to mimic the preparation methods, nutritional profile, and sensorial qualities of meat. PBMAs are currently subject to a controversial debate concerning their health value. Here, we reviewed PBMAs' potential renal acid load (PRAL).

Quantifying the potential renal acid load of edible mushrooms.

The capability of any food to alter net endogenous acid or base production can be estimated using the potential renal acid load (PRAL) estimation method. The PRAL of edible mushrooms has been rarely examined; thus a quantification study of n = 37 edible mushroom species was performed. Results revealed a heterogeneous picture: although the most commonly consumed mushrooms (e.

Effective management of recurrent Doege-Potter syndrome with somatostatin-analogues: A case report.

Background: Doege-Potter syndrome is defined as paraneoplastic hypoinsulinemic hypoglycemia associated with a benign or malignant solitary fibrous tumor frequently located in pleural, but also extrapleural sites. Hypoglycemia can be attributed to paraneoplastic secretion of "Big-IGF-II," a precursor of Insulin-like growth factor-II. This prohormone aberrantly binds to and activates insulin receptors, with consecutive initiation of common insulin actions such as inhibition of gluconeogenesis, activation of glycolysis and stimulation of cellular glucose uptake culminating in recurrent tumor-induced hypoglycemic episodes.

Long-term trends in international medical electives fees: a database mining study.

Background: Abroad medical electives are recognized as high-impact practice and considered a necessity to provide global health training. As of recently, the COVID-19 pandemic and its related travel restrictions prohibited most international elective activities. Another important barrier to abroad electives that received comparably little attention is elective and application fees, which - combined - may be as high as $5000 per month, and may prevent students with limited financial resources from applying for an international elective.

Bowel health, defecation patterns and nutrient intake following adoption of a vegan diet: a randomized-controlled trial.

Background: The beneficial effects of a plant-based diet on gut microbiota diversity are well documented, however, its impact on clinical bowel health and defecation patterns are less well understood. Vegetarian diets have been associated with a higher bowel movement (BM) frequency as well as softer stools in cross-sectional studies. The effects of the de-novo adoption of a vegan diet on bowel health, however, have never been investigated in a randomized-controlled trial.

Serum levels of copper but not zinc are associated with head and chest cold in the NHANES.

Background: Common colds are among the top reasons children miss school and adults miss work. The Centers for Disease Control and Prevention estimates that there are millions of cases of the common cold in the United States each year. The essential trace elements zinc and copper have immunomodulatory functions, and zinc has been reported to reduce the general risk of infection, whereas the copper-to-zinc ratio has been associated with an increased risk of incident infections in middle-aged men.

A cross-sectional study of nutritional status in healthy, young, physically-active German omnivores, vegetarians and vegans reveals adequate vitamin B status in supplemented vegans.

Background/objective: Plant-based diets reduce the risk of cardiovascular disease but also increase the risk of certain micronutrient deficiencies, particularly, of vitamin B12 (B12). The extent to which the unsupervised use of oral nutrient supplements is sufficient to prevent these deficiencies is not well established. We analyzed nutrient intake, laboratory biomarkers, supplementation behavior, and B12 status adequacy amongst young, healthy, physically active omnivores, lacto-ovo-vegetarians and vegans from Germany.

Nutrition facts labels: who is actually reading them and does it help in meeting intake recommendations for nutrients of public health concern?

Background: Fiber, potassium and calcium are nutrients of public health concern and their intakes in the United States are alarmingly low. The usage of nutrition facts labels has been reported to increase the odds for dietary reference intake of fiber in some studies. The overall evidence, however, is mixed, as some studies suggested that nutrition facts panels have little to no effect on average measures of diet quality.

The Role of Hemp ( L.) as a Functional Food in Vegetarian Nutrition.

Recently, there has been a renewed interest in and its uses. The recreational use of inflorescences as a source of THC has led to the legal restriction of cultivation to limit the detrimental effects of psychotropic substance abuse on health. However, this has also limited the cultivation of textile/industrial varieties with a low content of THC used for textile and nutritional purposes.

Dietary acid load decreases with age and is associated with sagittal abdominal diameter: a nationally representative quantification study in US adults.

Background: Dietary acid load (DAL) has been associated with frailty and hip fractures in older adults, who often have a reduced kidney function and thus compromised buffering capacities. Studies to quantify DAL in older adults are scarce and controversies persist as to whether DAL in- or decreases with age.

Aim: To enhance the understanding of DAL in older individuals, we examined its relationship with increasing age and selected anthropometric data in a well-characterized sample of US adults.

Dietary Acid Load and Cancer Risk: A Review of the Uruguayan Experience.

Dietary acid load (DAL) is recognized as a risk factor for several chronic disorders, including obesity, diabetes, and osteoporosis. Recent evidence suggests that an elevated DAL, as measured by the validated potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores, could also increase the risk for several cancers. This narrative review summarizes the potential role of DAL in Uruguayan cancer patients and outlines the potentially involved pathophysiological pathways that mediate the role of DAL in both cancer development and growth.

Dietary Acid Load Is Not Associated with Serum Testosterone in Men: Insights from the NHANES.

The dietary acid load (DAL) is a novel marker of overall diet quality, which has been associated with overweight, type 2 diabetes and altered glucocorticoid secretion. A potential association with sex hormones is thus not inconceivable. We investigated whether DAL was associated with serum total testosterone concentrations of men in the National Health and Nutrition Examination Survey.

Dietary Acid Load Correlates with Serum Amino Acid Concentrations after a Four-Week Intervention with Vegan vs. Meat-Rich Diets: A Secondary Data Analysis.

Chronic low-grade metabolic acidosis is now a common phenomenon in the Western world. The high dietary intake of sulfur-containing amino acids in the form of processed meats results in an excessive release of acid in the form of protons and non-metabolizable acidic anions. The kidneys produce increasing amounts of ammonia to excrete this acid.
