OBJECTIVE Exercise training has antihypertensive and renoprotective effects in humans and rats. However, the effects of exercise training on renal disorders that occur with salt-sensitive hypertension remains unclear. The study aim was to investigate the effects and mechanisms of exercise training on renal function in a rat model of salt-sensitive hypertension. METHODS Six-week-old male Dahl salt-sensitive rats were divided into normal-salt (0.6% NaCl) diet, high-salt (8% NaCl) diet, and high-salt diet with exercise training groups. selleckchem The high-salt diet with exercise training group underwent daily treadmill running for 8 weeks. RESULTS The high-salt diet induced severe hypertension and renal dysfunction. Exercise training significantly improved high-salt diet-induced urinary protein, albumin, and L-type fatty acid-binding protein excretion, and glomerulosclerosis but not renal interstitial fibrosis without changing blood pressure. Exercise training significantly attenuated high-salt diet-induced oxidative stress in the kidneys and decreased high-salt diet-stimulated xanthine oxidoreductase activity but not nicotinamide adenine dinucleotide phosphate oxidase activity. The high-salt diet did not change urinary excretion of 20-hydroxyeicosatetraenoic acid and decreased cytochrome P450 4A protein expression in the kidneys. Exercise training increased urinary 20-hydoroxyeicosatetraenoic acid excretion and renal cytochrome P450 4A protein expression. CONCLUSION Exercise training improved renal disorders without lowering blood pressure in Dahl salt-sensitive rats. Exercise training also decreased oxidative stress and increased 20-hydroxyeicosatetraenoic acid production in the kidneys. These results suggest that improvements in oxidative stress and 20-hydroxyeicosatetraenoic acid production may be potential mechanisms by which exercise training improved renal disorders in Dahl salt-sensitive rats.OBJECTIVES Hypertension phenotypes differ between Africans and Europeans, with a greater prevalence of low renin salt-sensitive hypertension and greater predisposition to adverse cardiac remodelling in Africans. To elucidate the roles of inheritance and environment in determining hypertension phenotypes in sub-Saharan Africans and white Europeans, we compared phenotypes in white individuals in the UK (n = 132) and in African individuals in the UK (n = 158) and Nigeria (n = 179). METHODS Biochemistry, blood pressure, left ventricular structure (echocardiography) and 24-h urinary collections of sodium and potassium were measured. link2 RESULTS Twenty-four-hour urinary sodium/potassium ratio was lower in individuals living in Europe (both African and white 2.32 ± 0.15 and 2.28 ± 0.17) than in individuals in Nigeria (4.09 ± 0.26, both P  less then  0.001) reflecting proportionately higher potassium intake in Europeans (African or white) than African residents. Plasma renin was lower in Africans irrespective of residency than white Europeans, but aldosterone was higher in Africans in Europe than those in Africa (466.15 ± 32.95 vs. 258.60 ± 17.42 pmol/l, P  less then  0.001). Left ventricular mass index adjusted for blood pressure and other confounders was greatest in Africans in Europe (103.27 ± 2.32 g/m) compared with those in Africa (89.28 ± 1.98 g/m) or white Europeans (86.77 ± 2.63 g/m, both P  less then  0.001). CONCLUSION Despite a similar low renin state in African origin individuals living in Europe and Africa, a higher aldosterone level, possibly related to higher potassium intake or other environmental factors, may contribute to greater cardiac remodelling in Africans in Europe.OBJECTIVES To describe the prevalence of healthy vascular aging (HVA), normal vascular aging and early vascular aging (EVA) in a sample of Spanish population without cardiovascular disease. The relationship of vascular aging with lifestyle, cardiovascular risk factors, psychological and inflammatory risk factors is also analyzed. METHODS A total of 501 participants were recruited (49.70% men, aged 55.90 ± 14.24 years) by random sampling. Vascular aging was defined in three steps Step 1 participants with vascular damage in carotid arteries or peripheral artery disease were classified as EVA. Step 2 with the percentiles of carotid-to-femoral pulse wave velocity (cfPWV) we used three criteria, first, the 10th and 90th cfPWV percentiles of the population studied by age and sex; second, the 10th and 90th percentiles of the European population reference values and third, the 25th and 75th cfPWV percentiles of the population studied by age and sex. Step 3 participants with hypertension or type 2 diabetes mellitus ingher in men. Study results suggest that preventive strategies aimed at increasing physical activity, reducing sedentary time and decreasing obesity and insulin resistance improve vascular aging.OBJECTIVES The aim of this study was to determine if a perineorrhaphy at the time of apical pelvic organ prolapse surgery positively affects women's body image. METHODS This is a randomized controlled trial of women undergoing apical suspension procedures in which women (GH ≥2 cm to ≤6 cm) received either perineorrhaphy or no perineorrhaphy. The primary aim compared body image between the groups postoperatively using the Body Image in Pelvic Organ Prolapse (BIPOP) questionnaire. Secondary outcomes included prolapse stage, pain, pelvic floor muscle strength, pelvic floor symptoms, and sexual function. Between- and within-group differences were compared using Fisher exact test for categorical variables and t tests for continuous variables. When continuous variables were not normally distributed, the Welch-Satterthwaite test was used. Within-group analyses were performed via paired t tests for select continuous variables. RESULTS Forty-six women were enrolled; 45 (97.8%) completed the 6-week assessment and 38 (82.6%) completed the 3-month assessment. There were no differences in baseline characteristics. Although women within groups had an expected improvement in mean Body Image in Pelvic Organ Prolapse and subscale scores between baseline and 3 months (P less then 0.05), there were no differences in the mean scores between groups. In addition, there were no differences between groups in any of the secondary outcomes. CONCLUSIONS Performance of apical prolapse surgery improved women's body image, irrespective of performance of a perineorrhaphy. Other important outcomes, including pain, did not differ between women in the 2 groups. These findings demonstrate the need for further trials to investigate the utility of this procedure.OBJECTIVES There are multiple approaches to vaginectomy for the purpose of masculinizing gender-affirming genital surgery including mucosal fulguration and excision. The outcomes of the approaches are not well described. We aim to describe the surgical outcomes of gender-affirming vaginectomy and colpocleisis by complete mucosal excision. METHODS We performed a case series study of 40 transmasculine patients who underwent gender-affirming vaginectomy and colpocleisis. Vaginectomy was performed by complete excision of the vaginal mucosa via a transperineal approach. We recorded perioperative outcomes and operative time. We performed a multivariate analysis to assess patient factors on operative outcomes. RESULTS Forty vaginectomies were performed between September 2016 and April 2019, 27 (67.5%) in phalloplasty patients and 13 (32.5%) in metoidioplasty patients. Perioperative complications included 2 blood transfusions, 1 pelvic hematoma, and 1 Clostridium cifficile colitis. No urethral fistulae to the vaginal space, mucoceles, or visceral injures were seen with a median follow-up of 7.7 months. Operative time decreased significantly with later surgery year. CONCLUSIONS This is a large series studying the outcomes of gender-affirming vaginectomy by complete mucosal excision approach in the literature. Perioperative complications were low. Operative time decreased overtime such that after approximately 20 cases, the procedure fairly consistently takes 2 to 2.5 hours to perform.OBJECTIVE The aims of the study were to determine the rate of urinary tract infection (UTI) in women undergoing colpopexy and to evaluate risk factors and timing for postoperative UTI. METHODS This was a retrospective cohort study using the American College of Surgeons National Surgical Quality Improvement Program database from 2010 to 2017. Patients were grouped into those with and without UTI. Pairwise analysis between groups was performed using χ and Fisher exact test. Multivariable logistic regression was used to identify independent predictors of UTI. RESULTS Of 23,097 women who underwent colpopexy, 1079 (4.7%) experienced a postoperative UTI. Urinary tract infection was most frequently diagnosed in the second week after surgery (38.2%), compared with week 1 (19.9%), 3 (22.8%), and 4 (19.1%) (P less then 0.001). Patients diagnosed with a UTI were more likely to have insulin-dependent diabetes (2.8% vs 1.7%, P = 0.006), coagulopathy (1.3% vs 0.7%, P = 0.04), and chronic steroid use (2.7% vs 1.8%, P = 0.004). Patients with a UTI versus those without a UTI were more likely to have undergone an intraperitoneal or extraperitoneal vaginal colpopexy (37.8% vs 30.5%, P less then 0.001) and (29.8% vs 25.6%, P = 0.003), respectively, and more likely to undergo combined anterior and posterior colporrhaphy (17.1% vs 12.2%, P less then 0.001). After logistic regression, intraoperative cystotomy repair (adjusted odds ratio = 2.93, 95% confidence interval = 1.54-5.59) was the most significant risk factor. CONCLUSIONS Postoperative UTI after colpopexy occurred less frequently than previously reported. Vaginal colpopexy is associated with a higher risk of UTI than abdominal or laparoscopic colpopexy.BACKGROUND Iron-deficiency anemia is a common perioperative condition and increases perioperative morbidity and mortality. Timely diagnosis and treatment are important. This retrospective cohort study tested the hypothesis that a newly developed preprocedure evaluation protocol diagnoses more patients with iron-deficiency anemia than the traditional practice of obtaining a complete blood count followed by iron studies. METHODS The preprocedure anemia evaluation is an order for a complete blood count and reflex anemia testing, which can be completed with a single patient visit. A hemoglobin concentration of 12 g/dl or less with serum ferritin concentration less than 30 ng/ml or transferrin saturation less than 20% defined iron-deficiency anemia. Northwestern Medicine's database was queried for preoperative clinic patients, age 16 to 89 yr, before (2015 to 2016) and after (2017 to 2018) protocol implementation. The proportion of patients diagnosed with iron-deficiency anemia before and after the preprocedure ant, allowing anemia evaluation with a single patient visit. link3 WHAT WE ALREADY KNOW ABOUT THIS TOPIC Iron-deficiency anemia is common and increases perioperative morbidity and mortalityTimely diagnosis facilitates treatment and may reduce complications WHAT THIS ARTICLE TELLS US THAT IS NEW The investigators implemented a novel screening system in which anemia automatically triggered evaluation for iron deficiency using previously collected bloodThe automated system identified iron-deficiency anemia far better than clinicians using normal procedures.
