Primary focal hyperhidrosis is a benign condition of unknown etiology. Tap water iontophoresis has long been known to inhibit sweat production. The mechanism of reduced hyperhidrosis by iontophoresis is not completely clear. For operational convenience, our patients received their treatments at different intervals to those recommended by the manufacturer of the iontophoresis unit. We performed a retrospective audit to evaluate the effectiveness of tap water iontophoresis using this regimen. This new treatment regimen was effective at controlling palmoplantar hyperhidrosis. Minimal undesirable effects such as mild skin irritation and erythema were noted but none were severe enough to necessitate discontinuation of treatment. In conclusion, tap water iontophoresis is a safe and effective treatment of palmar and plantar hyperhidrosis when used on Monday, Wednesday, and Friday for 4 weeks. Continued treatment is needed to maintain the effect and many patients go on to purchase their own machines. This technique should be considered prior to systemic or aggressive surgical intervention.

The health burden of waterborne nontuberculous mycobacteria (NTM) is a rising concern. While the water supply systems can serve as a potential reservoir for NTM, their abundance, diversity, and transmission pathways remain unknown. This study aimed to characterize the prevalence and regrowth of NTM in building water supply system in a hospital where many M.

Low levels of human norovirus (HuNoV) in food and environment present challenges for nucleic acid detection. This study reported an evaporation-enhanced hydrogel digital reverse transcription loop-mediated isothermal amplification (HD RT-LAMP) with interfacial enzymatic reaction for sensitive HuNoV quantification in food and water. By drying samples on a chamber array chip, HuNoV particles were enriched in situ.

Background/objectives: Urinary fluoride (UF) is the most well-established biomarker for fluoride exposure, and understanding its distribution can inform risk assessment for potential adverse systemic health effects. To our knowledge, this study is the first to report distributions of UF among youth according to sociodemographic factors in a nationally representative United States (US) sample.
Methods: The study included 1191 children aged 6-11 years and 1217 adolescents aged 12-19 years from the National Health and Nutrition Examination Survey (NHANES) 2015-2016.

The prevalence of metabolic syndrome has been exponentially increasing in recent decades. Thus, there is an increasing need for affordable and natural interventions for this disorder. We explored the effect of chrysin, a dietary polyphenol, on hepatic lipid and glycogen accumulation, metabolic dysfunction-associated fatty liver disease (MAFLD) activity score and oxidative stress and on hepatic and adipose tissue metabolism in rats presenting metabolic syndrome-associated conditions.

Melatonin is involved in various functions such as the timing of circadian rhythms, energy metabolism, and body mass gain in experimental animals. However, its effects on adipose tissue lipid metabolism are still unclear. This study analyzes the effects of melatonin on the relative gene expression of lipolytic proteins in rat mesenteric adipose tissue and free fatty acid (FFA) and glycerol plasma levels of male Wistar rats fed a high-fat (HFD) or maintenance diet.
