Association of the VEGF 2578C>A Polymorphism With Metabolic Syndrome and Erectile Dysfunction.

Accumulating evidence suggests a link between vascular endothelial growth factor (VEGF), erectile dysfunction (ED), and metabolic syndrome (Mets), possibly because VEGF can alter the physiological pathways involved in the regulation of endothelial cell proliferation. This study aimed to investigate the genetic susceptibility of VEGF 2578C>A polymorphism to the development of ED and Mets. Collected data included five-item International Index of Erectile Function (IIEF-5), components of Mets, and VEGF 2578C>A polymorphism.

Benchmark Dose of Melamine Exposure for a Renal Injury Marker Mediated by Oxidative Stress: Examples in Patients with Urolithiasis and Occupational Workers.

Establishing a safe exposure level from epidemiological studies while providing direct hazard characterization in humans often faces uncertainty in causality, especially cross-sectional data. With advances in molecular epidemiology, it is reasonable to integrate identified intermediate biomarkers into health risk assessment. In this study, by considering the mediation of the oxidative stress marker malondialdehyde (MDA), we explored the exposure threshold of melamine on the early renal injury marker N-acetyl-β-D glucosaminidase (NAG).

Metabolic dysfunction-associated fatty liver disease is an early predictor for testosterone deficiency in aging men without metabolic syndrome.

Background And Aims: Metabolic dysfunction-associated fatty liver disease (MAFLD) has emerged as a valuable marker for identifying individuals at increased risk of metabolic dysfunction, liver-related complications, and cardiovascular disease. However, the association between MAFLD and testosterone deficiency (TD) in aging men remains poorly understood. This study aimed to investigate the association between MAFLD and the risk of TD in aging Taiwanese men, with a specific focus on those without metabolic syndrome (MetS).

Sex-specific interactive effect of melamine and DEHP on a marker of early kidney damage in Taiwanese adults: A national population-based study from the Taiwan Biobank.

Taiwan had the high incidence of chronic kidney disease (CKD) worldwide. Our objective was to examine associations between daily exposure of phthalates and melamine, two common nephrotoxins, and kidney damage risk in a well-established nationwide cohort. Study subjects were from Taiwan Biobank (TWB) with existing data of questionnaire and biochemical examinations.

Consensus of Experts on the Treatment of Sexual Dysfunction after Surgery for Prostate Cancer in Taiwan.

According to the Taiwan Cancer Report, in 2018, prostate cancer was one of the top five cancers reported in men. Each year, many patients with prostate cancer undergo radical prostatectomy (RP) therapy. One of the most common RP complications is erectile dysfunction (ED).

Benchmark dose in the presence of coexposure to melamine and diethylhexyl phthalate and urinary renal injury markers in pregnant women.

Environmental exposures to mixtures of toxic chemicals have potential interaction effects that may lead to hazard index values exceeding one. However, current regulation levels, such as tolerable daily intake (TDI), are mostly based on experimental studies conducted with a single chemical compound. In this study, we assessed the relationships between melamine and di-(2-ethylhexyl) phthalate (DEHP) exposure and their coexposure with the early renal injury markers N-acetyl -D-glucosaminidase (NAG), albumin/creatinine ratio (ACR), and microalbuminuria in 1236 pregnant women.

-Octyl Caffeamide, a Caffeic Acid Amide Derivative, Prevents Progression of Diabetes and Hepatic Steatosis in High-Fat Diet Induced Obese Mice.

The underlying pathological mechanisms of diabetes are complicated and varied in diabetic patients, which may lead to the current medications often failing to maintain glycemic control in the long term. Thus, the discovery of diverse new compounds for developing medicines to treat diabetes and its complications are urgently needed. Polyphenols are metabolites of plants and have been employed in the prevention and treatment of a variety of diseases.

Avatar-like body imaging of dermal exposure to melamine in factory workers analyzed by ambient mass spectrometry.

Ambient mass spectrometry thermal desorption-electrospray ionization/mass spectrometry (TD-ESI/MS) can rapidly identify chemicals without pretreatment of biological samples. This study used a rapid semi-quantitative TD-ESI/MS screening technique for the probe skin sampling of melamine workers occupationally exposed to different ambient melamine concentrations to create avatar-like body images, which were then used to study temporal and dynamic changes in nephrotoxic melamine exposure. We enrolled four voluntary melamine workers from one factory, each from one of four worksites.

Diminishment of Nrf2 Antioxidative Defense Aggravates Nephrotoxicity of Melamine and Oxalate Coexposure.

Chronic kidney disease (CKD) usually causes devastating healthy impacts on patients. However, the causes affecting the decline of kidney function are not fully revealed, especially the involvement of environmental pollutants. We have revealed that exposure to melamine, a ubiquitous chemical in daily life, is linked to adverse kidney outcomes.

Melamine and oxalate coexposure induces early kidney tubular injury through mitochondrial aberrations and oxidative stress.

Exposure to melamine, which is ubiquitous in daily life, is linked to adverse kidney outcomes. The melamine tolerable daily intake in humans is based on the no-observed-effect-level (NOEL) established in a single-toxicant murine model. However, humans are often simultaneously exposed to multiple environmental nephrotoxicants.

Melamine exposure threshold in early chronic kidney disease patients - A benchmark dose approach.

Environmental melamine exposure has been associated with deteriorating kidney function in early-stage chronic kidney disease patients. In this study, a benchmark dose (BMD) approach was used to establish melamine exposure threshold in 293 patients with eGFR≥30 ml/min per 1.73 m.

Fatty liver index is associated with the risk of testosterone deficiency in aging men without metabolic syndrome.

Objectives: Non-alcoholic fatty liver disease (NAFLD) is suggested to be a precursor of metabolic syndrome (MetS) and could influence the risk of testosterone deficiency (TD). Fatty liver index (FLI) is a simple and useful screening tool for NAFLD. We determined the association between the risk of NAFLD assessed by FLI and TD in aging Taiwanese men, especially those without MetS.

Clinical Practice Guideline Recommendation on the Use of Low Intensity Extracorporeal Shock Wave Therapy and Low Intensity Pulsed Ultrasound Shock Wave Therapy to Treat Erectile Dysfunction: The Asia-Pacific Society for Sexual Medicine Position Statement.

Published literature shows low intensity extracorporeal shock wave therapy (LIESWT) and low intensity pulsed ultrasound (LIPUS) therapy to improve erectile function and penile hemodynamic by inducing neovascularisation and promoting tissue regeneration. Key opinion leaders across the Asia Pacific region attended the recent biennial meeting of the Asia Pacific Society for Sexual Medicine in Australia, and presented the current evidence on LIESWT and LIPUS for erectile dysfunction (ED). The clinical findings were internally discussed, and the quality of evidence was graded based on the Oxford Centre for Evidence-Based Medicine recommendations.

A probabilistic approach for benchmark dose of melamine exposure for a marker of early renal dysfunction in patients with calcium urolithiasis.

Environmental exposure to melamine has been associated with early renal injury in urolithiasis patients even when urinary concentrations of melamine are low. The aim of this study was to derive a benchmark dose (BMD) for melamine for urolithiasis patients. To do this, one-spot urine sample from 309 participants was obtained to measure urinary melamine and N-acetyl β-D-glucosaminidase (NAG), an early renal damage biomarker.

Interrelationship of environmental melamine exposure, biomarkers of oxidative stress and early kidney injury.

Melamine contamination has remained pervasive in the environment even after the 2008 toxic milk scandal. Exposure to chronic low dosages of melamine is known to induce renal tubular damage, increasing the risk of stone formation and early kidney injury. This damage may come about via increased oxidative stress, but no studies of this possibility have been performed in humans.

Urinary Melamine Levels and Progression of CKD.

Background And Objectives: CKD is a global public health problem. Some cross-sectional studies have associated environmental melamine exposure with kidney diseases, but evidence is limited.

Design, Setting, Participants, & Measurements: We conducted this prospective cohort study to enroll patients with eGFR≥30 ml/min per 1.

Purpose: Applying low-intensity extracorporeal shockwave therapy (LI-ESWT) has been reported to improve symptoms of refractory chronic pelvic pain syndrome (CPPS) in short-term follow-up. This study aims to demonstrate the effect of LI-ESWT on refractory CPPS over the span of a 12-month follow-up.

Materials And Methods: This was an open-label, single-arm prospective study.

Hepatocyte Nuclear Factor-4α P2 Promoter Variants Are Associated With the Risk of Metabolic Syndrome and Testosterone Deficiency in Aging Taiwanese Men.

Background: Hepatocyte nuclear factor-4α (HNF4A) can influence the risk of insulin resistance that is postulated to be an important link between metabolic syndrome (MetS) and testosterone deficiency (TD) in men.

Aim: To investigate the relationship between single-nucleotide polymorphisms (SNPs) of HNF4A and the risk of developing MetS and TD in a population of aging Taiwanese men.

Methods: A free health screening of men over 40 years of age was conducted in a medical center in Kaohsiung City, Taiwan.

Efficacy of Low-Intensity Extracorporeal Shock Wave Therapy on Men With Chronic Pelvic Pain Syndrome Refractory to 3-As Therapy.

Managing patients with chronic pelvic pain syndrome (CPPS) refractory to the traditional 3-As therapy (antibiotics, alpha-blockers, and anti-inflammatories) is a challenging task. Low-intensity extracorporeal shock wave therapy (LI-ESWT) was recently reported to be able to improve pain, urinary symptoms, and even sexual function by inducing neovascularization and anti-inflammation, reducing muscle tone, and influencing nerve impulses. This study evaluates whether combined treatment with LI-ESWT can restore clinical ability and quality of life (QoL) in patients refractory to 3-As therapy.

Urinary melamine excretion and increased markers of renal tubular injury in patients with calcium urolithiasis: A cross-sectional study.

Environmental low-dose melamine exposure has been associated with urolithiasis risk in adults, but it is unclear if this exposure can cause early renal damage. This cross-sectional study investigated the association of this exposure and early renal damage in patients with calcium urolithiasis. We recruited patients diagnosed with upper urinary tract calcium urolithiasis from three hospitals in southwestern Taiwan between November 2010 and January 2015.

Low-Intensity Extracorporeal Shockwave Therapy Can Improve Erectile Function in Patients Who Failed to Respond to Phosphodiesterase Type 5 Inhibitors.

Managing patients with erectile dysfunction (ED) who failed to respond to phosphodiesterase type 5 inhibitors (PDE5is) is a challenging task. Recently, low-intensity extracorporeal shockwave therapy (LI-ESWT) was reported to improve ED by enhancing perfusion of the penis. The current study was performed to evaluate whether combined treatment with LI-ESWT and PDE5is can restore erectile function in patients who failed to respond to PDE5is alone.
