Association of dietary vitamin E intake with current stone formation: A NHANES analysis 2017 - 2020.

Introduction: Free radical-mediated oxidative renal tubular injury secondary to hyperoxaluria is a proposed mechanism in the formation of calcium oxalate stones. Vitamin E, an important physiologic antioxidant, has been shown in rat models to prevent calcium oxalate crystal deposition. Our objective was to determine if low dietary vitamin E intake was associated with a higher incidence of stones.

Differential Effect of TRPV1 Modulators on Neural and Behavioral Responses to Taste Stimuli.

In our diet, we ingest a variety of compounds that are TRPV1 modulators. It is important to understand if these compounds alter neural and behavioral responses to taste stimuli representing all taste qualities. Here, we will summarize the effects of capsaicin, resiniferatoxin, cetylpyridinium chloride, ethanol, nicotine, -geranyl cyclopropylcarboxamide, Kokumi taste peptides, pH, and temperature on neural and behavioral responses to taste stimuli in rodent models and on human taste perception.

Accurate Documentation Contributes to Guideline-concordant Surveillance of Nonmuscle Invasive Bladder Cancer: A Multisite Department of Veterans Affairs Study.

Objective: To determine if accurate documentation of bladder cancer risk was associated with a clinician surveillance recommendation that is concordant with AUA guidelines among patients with nonmuscle invasive bladder cancer (NMIBC).

Methods: We prospectively collected data from cystoscopy encounter notes from four Department of Veterans Affairs (VA) sites to ascertain whether they included accurate documentation of bladder cancer risk and a recommendation for a guideline-concordant surveillance interval. Accurate documentation was a clinician-recorded risk classification matching a gold standard assigned by the research team.

Attitudes towards disposition of cryopreserved sperm in the event of death.

Introduction: To evaluate patient preference for sperm disposition in case of death based on demographic factors and infertility etiology.

Materials And Methods: This retrospective cohort study was performed at a university hospital-affiliated fertility center. Charts of 550 men undergoing cryopreservation for assisted reproductive technologies (ART) between 2016-2019 were reviewed to create a descriptive dataset.

"Our Mothers Have Handed That to Us. Her Mother Has Handed That to Her": Urban Aboriginal and Torres Strait Islander Yarning about Community Wellbeing, Healthy Pregnancies, and the Prevention of Fetal Alcohol Spectrum Disorder.

In Australia, fetal alcohol spectrum disorder (FASD) is a largely hidden disability that is currently under-recognized, under-resourced, and under- or misdiagnosed. Unsurprisingly, efforts to prevent FASD in urban Aboriginal and Torres Strait Islander communities are lacking. Further, mainstream approaches are not compatible with diverse and distinct Aboriginal and Torres Strait Islander ways of approaching family, pregnancy, and parenting life.

Updates in the Treatment of Non-Metastatic Castrate-Resistant Prostate Cancer: The Benefit of Second-Generation Androgen Receptor Antagonists.

Objective: To review pharmacology, efficacy, safety, and considerations for use, of second-generation androgen receptor (AR) antagonists in treatment of nonmetastatic castrate-resistant prostate cancer (M0CRPC).

Data Sources: Conducted search in PubMed and Google scholar (January, 1, 2002-December 31, 2022), using relevant terms.

Study Selection And Data Extraction: Relevant English-language studies, conducted in humans evaluating second-generation AR antagonists for M0CRPC, and additional articles and package inserts were considered.

Improving paediatric antimicrobial stewardship in remote and regional Queensland hospitals: development and qualitative evaluation of a tailored intervention for intravenous-to-oral antibiotic switching.

Objectives: Timely intravenous-to-oral antibiotic switching for children is important for paediatric antimicrobial stewardship (AMS). However, low decision-making confidence and fragmentation of patient care can hamper implementation, with difficulties heightened regionally where AMS programmes for children are lacking. The aim of this study was to develop and evaluate user-led creation and implementation of an intervention package for early intravenous-to-oral switching at regional hospitals in Queensland, Australia.

Relationship between ENaC Regulators and SARS-CoV-2 Virus Receptor (ACE2) Expression in Cultured Adult Human Fungiform (HBO) Taste Cells.

In addition to the α, β, and γ subunits of ENaC, human salt-sensing taste receptor cells (TRCs) also express the δ-subunit. At present, it is not clear if the expression and function of the ENaC δ-subunit in human salt-sensing TRCs is also modulated by the ENaC regulatory hormones and intracellular signaling effectors known to modulate salt responses in rodent TRCs. Here, we used molecular techniques to demonstrate that the G-protein-coupled estrogen receptor (GPER1), the transient receptor potential cation channel subfamily V member 1 (TRPV1), and components of the renin-angiotensin-aldosterone system (RAAS) are expressed in δ-ENaC-positive cultured adult human fungiform (HBO) taste cells.

"The Problem Is that We Hear a Bit of Everything…": A Qualitative Systematic Review of Factors Associated with Alcohol Use, Reduction, and Abstinence in Pregnancy.

Understanding the factors that contribute to women's alcohol use in pregnancy is critical to supporting women's health and wellness and preventing Fetal Alcohol Spectrum Disorder. A systematic review of qualitative studies involving pregnant and recently postpartum women was undertaken to understand the barriers and facilitators that influence alcohol use in pregnancy (PROSPERO: CRD42018098831). Twenty-seven ( = 27) articles were identified through EMBASE, CINAHL, PsycINFO, PubMed and Web of Science.

Interactions between Chemesthesis and Taste: Role of TRPA1 and TRPV1.

In addition to the sense of taste and olfaction, chemesthesis, the sensation of irritation, pungency, cooling, warmth, or burning elicited by spices and herbs, plays a central role in food consumption. Many plant-derived molecules demonstrate their chemesthetic properties via the opening of transient receptor potential ankyrin 1 (TRPA1) and transient receptor potential vanilloid 1 (TRPV1) channels. TRPA1 and TRPV1 are structurally related thermosensitive cation channels and are often co-expressed in sensory nerve endings.

"They Were Willing to Work with Me and Not Pressure Me": A Qualitative Investigation into the Features of Value of a Smoking Cessation in Pregnancy Program for Aboriginal and Torres Strait Islander Women.

With tobacco commonly used for stress relief, smoking cessation during pregnancy can present challenges for women facing stressful circumstances. This can be pronounced for Aboriginal and Torres Strait Islander women who experience disproportionately high smoking rates during pregnancy and also have a greater intersection of stressors from social disadvantage, institutional racism and trauma. To contribute understandings into how women can be best supported at this time, this study identified the features of value of an Aboriginal and Torres Strait Islander pregnancy smoking cessation program that addressed the contexts of women's lives in culturally affirming and strength-based ways.

Mechanism of Diuresis and Natriuresis by Cannabinoids: Evidence for Inhibition of Na-K-ATPase in Mouse Kidney Thick Ascending Limb Tubules.

The endocannabinoid, anandamide (AEA), stimulates cannabinoid receptors (CBRs) and is enriched in the kidney, especially the renal medulla. AEA infused into the renal outer medulla of mice stimulates urine flow rate and salt excretion. Here we show that these effects are blocked by the CBR type 1 (CB1) inverse agonist, rimonabant.

Amyloid Deposition of the Bilateral Ureters in a Patient With Chronic Systemic AL Amyloidosis.

Amyloid of the ureter is a rare disease with less than 25 cases reported in the literature. Despite being rare, it remains an important entity as it is typically confused with a primary neoplastic process of the urinary system. We report a case of a 68-year-old male with a history of cutaneous amyloid with late presentation of bilateral ureteral involvement.

Kokumi Taste Active Peptides Modulate Salt and Umami Taste.

Kokumi taste substances exemplified by γ-glutamyl peptides and Maillard Peptides modulate salt and umami tastes. However, the underlying mechanism for their action has not been delineated. Here, we investigated the effects of a kokumi taste active and inactive peptide fraction (500-10,000 Da) isolated from mature (FII) and immature (FII) Ganjang, a typical Korean soy sauce, on salt and umami taste responses in humans and rodents.

Re-evaluating the utility of routine postoperative laboratory tests after primary total knee arthroplasty.

Background: While advancements in surgery and reduced complication rates have made total knee arthroplasty (TKA) one of the most successful and cost-effective procedures in orthopaedic surgery, routine postoperative laboratory tests are still being ordered without evidence as to their necessity. With expansion of the bundled payment models, there may exist an opportunity to cut overall costs while maintaining quality of care by eliminating unnecessary interventions. The objective of this study was to examine the utility of routine postoperative laboratory tests in TKA.

A mixed methods exploratory study tackling smoking during pregnancy in an urban Aboriginal and Torres Strait Islander primary health care service.

Background: Pregnancy can be a time of joy and a time of significant stress. For many Aboriginal and Torres Strait Islander (hereafter, respectfully, Indigenous) women, cigarette smoking, even during pregnancy, is a socially sanctioned behavioural response to stress. Indigenous women smoke during pregnancy at higher rates than their non-Indigenous counterparts.

Regulation of gastric smooth muscle contraction via Ca2+-dependent and Ca2+-independent actin polymerization.

In gastrointestinal smooth muscle, acetylcholine induced muscle contraction is biphasic, initial peak followed by sustained contraction. Contraction is regulated by phosphorylation of 20 kDa myosin light chain (MLC) at Ser19, interaction of actin and myosin, and actin polymerization. The present study characterized the signaling mechanisms involved in actin polymerization during initial and sustained muscle contraction in response to muscarinic M3 receptor activation in gastric smooth muscle cells by targeting the effectors of initial (phospholipase C (PLC)-β/Ca2+ pathway) and sustained (RhoA/focal adhesion kinase (FAK)/Rho kinase pathway) contraction.

Nicotinic acetylcholine receptors (nAChRs) are expressed in Trpm5 positive taste receptor cells (TRCs).

Nicotine evokes chorda tympani (CT) taste nerve responses and an aversive behavior in Trpm5 knockout (KO) mice. The agonists and antagonists of nicotinic acetylcholine receptors (nAChRs) modulate neural and behavioral responses to nicotine in wildtype (WT) mice, Trpm5 KO mice and rats. This indicates that nicotine evokes bitter taste by activating a Trpm5-dependent pathway and a Trpm5-independent but nAChR-dependent pathway.

Understanding practitioner professionalism in Aboriginal and Torres Strait Islander health: lessons from student and registrar placements at an urban Aboriginal and Torres Strait Islander primary healthcare service.

Aboriginal and Torres Strait Islander peoples continue to be pathologised in medical curriculum, leaving graduates feeling unequipped to effectively work cross-culturally. These factors create barriers to culturally safe health care for Aboriginal and Torres Strait Islander peoples. In this pilot pre-post study, the learning experiences of seven medical students and four medical registrars undertaking clinical placements at an urban Aboriginal and Torres Strait Islander primary healthcare service in 2014 were followed.

Cyclic-AMP regulates postnatal development of neural and behavioral responses to NaCl in rats.

During postnatal development rats demonstrate an age-dependent increase in NaCl chorda tympani (CT) responses and the number of functional apical amiloride-sensitive epithelial Na+ channels (ENaCs) in salt sensing fungiform (FF) taste receptor cells (TRCs). Currently, the intracellular signals that regulate the postnatal development of salt taste have not been identified. We investigated the effect of cAMP, a downstream signal for arginine vasopressin (AVP) action, on the postnatal development of NaCl responses in 19-23 day old rats.

Nicotine-Induced Effects on Nicotinic Acetylcholine Receptors (nAChRs), Ca2+ and Brain-Derived Neurotrophic Factor (BDNF) in STC-1 Cells.

In addition to the T2R bitter taste receptors, neuronal nicotinic acetylcholine receptors (nAChRs) have recently been shown to be involved in the bitter taste transduction of nicotine, acetylcholine and ethanol. However, at present it is not clear if nAChRs are expressed in enteroendocrine cells other than beta cells of the pancreas and enterochromaffin cells, and if they play a role in the synthesis and release of neurohumoral peptides. Accordingly, we investigated the expression and functional role of nAChRs in enteroendocrine STC-1 cells.
