057), but at 9 months (p less then 0.001), it became significant. CONCLUSION Our study reveals that weight loss following BS causes improvements in CV risk factors, which is evident after 9 months of surgery.OBJECTIVE Isoproterenol (ISO)-induced heart failure is a standardized model for the study of beneficial effects of various drugs. Both apelin and angiotensin 1-7 have a cardiac protective effect. We assumed that co-therapy with apelin and angiotensin 1-7 (Ang (1-7)) may have synergistic cardioprotective effects against isoproterenol-induced heart failure. Methods The animals were randomly assigned to one of eight groups of seven animals in each group as follows (1) control I (saline; IP injection) (1) control II (saline; via mini-osmotic pump) (3) ISO (5 mg/ kg; IP), (4) Apelin (20μg/ kg; IP), (5) Ang (1-7) (30 μg/kg/day; via mini-osmotic pump), (6) Apelin+ISO, (7) Ang (1-7)+ISO, (8) Apelin+Ang (1-7)+ISO. Rat myocardial injury was induced by intraperitoneal injection of 5mg/kg of ISO for ten days. Apelin and Ang (1-7) were administered 30 minutes before ISO injection. RESULTS A decrease in systolic blood pressure (SBP; p less then 0.001), diastolic blood pressure (DBP; p less then 0.05), left ventricular systolic pressure (LVSP; p less then 0.001), left ventricular contractility (dP / dt max; p less then 0.001), relaxation (dP / dt min; p less then 0.001) and an increase in left ventricular end-diastolic pressure (LVEDP; p less then 0.001) were observed in ISO-treated rats. Plasma LDH and myocardial and plasma MDA were higher in the ISO heart than in controls (P less then 0.001). Histopathological examination of cardiac tissue showed myocardial fibrosis and leukocyte infiltration in ISO-treated rats as compared to control. Co- therapy with apelin and Ang (1-7) was more effective than either agent used alone in restoring these parameters to that of control rats. CONCLUSION The results of this study showed that the combination of apelin and ang (1-7) had a more cardioprotective effect than either used alone against ISO-induced heart failure, and co-therapy may be a useful treatment option for myocardial injuries and heart failure.OBJECTIVE Periesophageal vagal plexus injury is a complication of cryoablation for atrial fibrillation (AF). The aim of this study is to investigate the effect of cryoablation on esophageal functions and to determine the relationship between esophageal temperature and esophageal motility. METHODS Twenty patients with symptomatic paroxysmal AF who underwent cryoablation were included in this study. The lowest cryoballoon temperature for each pulmonary vein (PV) was recorded. Esophageal temperature was measured using an esophageal probe during each cryoapplication. Esophageal manometry was performed before the procedure and one day after the procedure for each patient in order to assess the esophageal functions. RESULTS During the procedure, the highest esophageal temperature change was found in the left-side PVs in 13 patients (65%) and in the right-side PVs in seven patients (35%). No correlation was found between the lowest cryoballoon temperature and esophageal temperature change (r=0.22, p=0.05). It was detected that the lower esophageal sphincter pressure and esophageal contraction amplitude pressure decreased after the procedure (before 19.7±9.3 mm Hg, after 14.3±4.9 mm Hg, p=0.001; before 84.5±28.3 mm Hg, after 72.7±34.3 mm Hg, p=0.005, respectively). Five patients (25%) developed gastrointestinal symptoms after the procedure. CONCLUSION During cryoablation, esophageal temperature measurement can be performed to reduce the probability of esophageal injury. Cryoablation affects esophageal motility, and esophageal manometry can be performed to detect esophageal motility impairments in patients with gastrointestinal symptoms.PURPOSE To determine the impact of a simple preoperative geriatric assessment on the outcome in older patients with recurrent urinary retention who underwent desobstructive surgery. PATIENTS AND METHODS Patients aged 75 years or older with recurrent urinary retention referred for TURP entered this prospective, multicentre study. Several demographic, intra- and postoperative parameters were assessed. Preoperative geriatric assessment was performed by the 7-item Canadian Study of Health and Ageing (CSHA) frailty scale (1 very fit, 7 severely frail; completion takes less than a minute). The main outcome parameters were successful voiding rates at discharge and 3 months postoperatively. RESULTS A total of 54 patients were recruited; 42 (77.8%) patients had a CSHA index of 1-3 and were considered as "fit", the remaining 12 (22.2%) formed the "frail" group (CSHA index 4-7). Age was identical in both cohorts (79.5 ± 3.7 vs. 79.7 ± 3.3 years); differences were demonstrable for the American Society of Anesthesiologists (ASA) score (p = 0.001), the number of daily medications (>4 32 vs. 75%, p = 0.02), falls within the past 6 months (12 vs. 33%), and the necessity of home/nursing care (5 vs. 42%, p = 0.004). Intra- and perioperative complications, duration of postoperative catheterization, and length of hospitalization were identical in both cohorts. The success rate at discharge was 80.6% in fit and 75.0% in frail patients; the respective values at 3 months were 95.2 and 83.3%. CONCLUSIONS A simple 1-min geriatric assessment tool can predict - to a certain extent - the outcome of desobstructive surgery in older patients with recurrent urinary retention. Fit patients achieve an excellent outcome while frail patients might benefit from a more in-depth urodynamic/geriatric evaluation. © 2020 S. Karger AG, Basel.INTRODUCTION Robotic surgery for the management of localized renal cell carcinoma (RCC) has gained increasing popularity during the last decade. An endophytic renal tumour represents a surgical technical challenge in terms of identification and resection related to the lack of external visual cues on the kidney surface. MATERIALS AND METHODS There is little evidence of functional outcomes of robotic surgery on treating endophytic masses. For this reason, we wanted to review the contemporary literature on the functional outcomes of endophytic RCC treated with robotic surgery. RESULTS Many studies investigating robotic partial nephrectomy for totally endophytic RCC confirmed the good functional results of this approach at intermediate follow-up. The greater relative importance of volume loss versus ischaemia duration in predicting long-term renal function after partial nephrectomy is now established, and the robotic technique may facilitate volume preservation. Accurate use of intra-operative ultrasonography, enucleation, and intra-operative techniques using near-infrared fluorescence imaging with indocyanine green dye could minimize excision of the parenchyma and prevent devascularization of adjacent healthy parenchyma. CONCLUSIONS Unfortunately, the overall quality of the literature evidence and the high risk of selection bias limit the possibility of any causal interpretation about the relationship between the surgical technique used and functional outcomes. © 2020 S. see more Karger AG, Basel.Background: Excessive scarring of filtering blebs is the main cause of surgical failure in glaucoma. Previous studies have highlighted the role of chloride channels in scar formation , whereas the role of chloride channels in scarring of filtering blebs has not been studied. OBJECTIVES To investigate the effects of the ClC-2 chloride channel on scar formation of filtering blebs after glaucoma filtering surgery. METHODS ClC-2 siRNA-transfected Human conjunctival fibroblasts (HconFs) were cultured in type I collagen gels in the presence of transforming growth factor (TGF)-β1. Collagen gel contraction was evaluated based on the gel area. 3D-cultured HConFs were treated with the chloride channel blocker NPPB in the presence of TGF-β1, and cell proliferation collagen synthesis and contractility were measured. The expression levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in HConFs were assessed by western blotting and q-PCR. RESULTS TGF-β1induced cell proliferation, cell cycle progression, collagen synthesis, and collagen gel contraction in HConFs. TGF-β1 increased MMP-2 and MMP-9 levels but inhibited the expression of TIMPs. NPPB and ClC-2 siRNA transfection inhibited TGF-β2-induced cell proliferation, cell cycle progression, collagen synthesis, and collagen gel contraction, mediated by HConFs. TGF-β2-induced increases in MMP-2 and MMP-9 were also inhibited by NPPB and ClC-2 siRNA transfection, but TIMP expression was increased by NPPB and ClC-2 siRNA transfection. CONCLUSIONS These findings demonstrate that ClC-2 chloride channels modulate TGF-β1-induced cell proliferation, collagen synthesis, and collagen gel contraction of HConFs by attenuating MMP-2 and MMP-9 production and by stimulating TIMP-1 production. NPPB may therefore prove to be of clinical value for the inhibition of scar formation of filtering blebs. © 2020 S.

However, the significance of longitudinal changes in antigravity muscle mass remains unclear in patients with COPD. OBJECTIVES The aims of this study were to investigate the factors associated with the longitudinal loss of antigravity muscles and whether the accelerated loss of these muscles has a negative impact on prognosis. METHODS This study was part of a prospective observational study at Kyoto University. We enrolled stable male patients with COPD who underwent longitudinal quantitative CT analysis of the cross-sectional area of the erector spinae muscles (ESMCSA) at an interval of 3 years. The associations between the rate of change in ESMCSA (%ΔESM) and clinical parameters, such as anthropometry, symptoms, lung function, exacerbation frequency, and all-cause mortality, were investigated. RESULTS In total, 102 stable male COPD patients were successfully evaluated in this study (71.3 ± 8.3 years, GOLD stage I/II/III/IV = 20/47/28/7 patients). ESMCSA significantly decreased from 30.53 to 28.98 cm2 (p less then 0.0001) in 3 years, and the mean %ΔESM was 5.21 ± 7.24%. The rate of survival during the observation period was 85.3% (87/102). Patients with an accelerated decline in ESMCSA (n = 31; more than double the mean rate of decline) had a significantly higher frequency of moderate-to-severe exacerbations during the interval (p = 0.015). They also had significantly worse survival (p = 0.035 by log-rank test). A multivariate Cox proportional hazard model showed that lower ESMCSA and greater %ΔESM decline were independently and significantly associated with mortality. CONCLUSIONS Frequent exacerbations were related to the loss of antigravity muscles in COPD patients. The accelerated loss of antigravity muscles was associated with a poor prognosis. © 2020 S.

A specific human milk microbiome has relatively recently been discovered, but its origin remains poorly understood. Data from experimental and clinical studies suggest that the bacteria in milk may originate in the maternal gut and be transported via a specific enteromammary pathway, the details of which have not been elucidated yet. The milk microbiome is affected by the maternal metabolic state, antibiotic use, as well as the mode of delivery. We are only in the initial stages of understanding the biological function of the milk microbiome and its potential contribution to infant gut colonization. Several clinical studies indicate, however, that despite considerable differences in the overall composition of the milk and infant gut microbiomes, specific bacteria are detectable both in human milk and infant feces, and that the bacteria in milk are a source of microbes colonizing the neonatal gut.
