In vitro release studies showed that recombinant human insulin was released with a constant rate for more than 30 days. The device was able to maintain a basal level of blood glucose in diabetic rats for a prolonged period of more than 30 days, simultaneously preventing a decrease in body weight. For assessing the pharmacological effect of the device on retinal function in diabetic rats, electroretinograms were conducted for 12 weeks. The reduction in amplitude and delay in implicit time were attenuated by the device during the initial 4 weeks of application. The increase in gene expression of protein kinase C (PKC)-γ and caspase-3 in the diabetic retina was also attenuated by the device. Immunohistochemistry showed that the increase in glial fibrillary acidic protein expression in the diabetic retina was attenuated by the device. Histological evaluation of subcutaneous tissue around the device showed the biocompatibility of the device. In conclusion, the insulin-releasing device attenuated the reduction of retinal function in STZ-induced diabetic conditions for 4 weeks and the efficacy of the device might be partially related to PKC signaling in the retina. The long-term ability to control the blood glucose level might help to reduce the daily frequency of insulin injections.The original version of this article unfortunately contained a mistake.Co-occurring psychiatric diagnoses are very common in individuals with ASD. Little is known about the effect that co-occurring psychiatric conditions may have on treatment response to CBT for children with ASD and anxiety. The present study examined the relationship between co-occurring psychiatric diagnoses and response to CBT for anxiety in ninety youth with ASD. Psychiatric complexity did not appear to differentially impact treatment response. A notable portion of youth with anxiety and externalizing disorders such as ADHD, no longer met criteria for those externalizing diagnoses following intervention. Results indicate that youth with ASD and anxiety present with complex psychiatric profiles and CBT for anxiety may positively affect co-occurring diagnoses. In addition, thorough and nuanced assessment of psychiatric symptoms in youth with ASD is needed to ensure the differentiation between diagnoses of anxiety and other co-occurring psychiatric symptoms.Autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) are highly heritable neurodevelopmental disorders that frequently co-occur. Both rare and common genetic variants are important for ASD and ADHD risk but their combined contribution to clinical heterogeneity is unclear. In a sample of 39 ASD and/or ADHD families we estimated the overall variance explained by known rare copy number variants (CNVs) and polygenic risk score (PRS) from common variants to be 10% in comorbid ASD/ADHD, 4% in ASD and 2% in ADHD. We show that burden of large, rare CNVs and PRS is significantly higher in adult ASD and/or ADHD patients with sustained need for specialist care compared to their unaffected relatives, while affected relatives fall in-between the two.Background and aims Levosimendan, a calcium (Ca2+)-sensitizing cardiotonic agent, is mainly used in patients with advanced heart failure. However, no research could explain how levosimendan reduces the mortality in advanced heart failure patients. We aim to illustrate the efficacy of levosimendan through clinical indexes. Methods We searched PubMed, Embase, and CENTRAL from 1994 to August 2019 to compare the efficacy of levosimendan infusion for the treatment of advanced heart failure with that of other agents (placebo, dobutamine, furosemide, and prostaglandin E1). Levels of B-type natriuretic peptide (BNP) and N-terminal pro BNP (NT-proBNP), and left ventricular ejection fraction (LVEF) and heart rate (HR) were analyzed. The count data were analyzed by the standardized mean difference (SMD) and its 95% confidence interval (CI) to determine the effect size. We chose the random effect model or the fixed effect model according to the heterogeneity. Results Nine randomized controlled trials with 413 patients were ultimately enrolled. Compared with other agents (placebo, dobutamine, furosemide, and prostaglandin E1), levosimendan significantly reduced the BNP level (SMD - 0.91; 95% CI - 1.44 to - 0.39; p = 0.001; I2 = 74.3%) and improved the LVEF (SMD 0.74; 95% CI 0.22-1.25; p = 0.005; I2 = 79.7%). However, levosimendan did not significantly change the HR (SMD 0.09; 95% CI - 0.24 to 0.42; p = 0.592; I2 = 51.5%). Meanwhile, we found that the main source of heterogeneity was the use of loaded or unloaded levosimendan. Conclusion Our meta-analysis suggests that intravenous levosimendan can reduce BNP level and increase LVEF in patients with advanced heart failure to reduce the mortality at the shortest follow-up available.Anthocyanins are water-soluble pigments in plants known for their photoprotective role against photoinhibitory and photooxidative damage under high light (HL). However, it remains unclear whether light-shielding or antioxidant activity plays a major role in the photoprotection exerted by anthocyanins under HL stress. To shed light on this question, we analyzed the physiological and biochemical responses to HL of three Arabidopsis thaliana lines (Col, chi, ans) with different light absorption and antioxidant characteristics. Under HL, ans had the highest antioxidant capacity, followed by Col, and finally chi; Col had the strongest light attenuation capacity, followed by chi, and finally ans. The line ans had weaker physiological activity of chloroplasts and more severe oxidative damage than chi after HL treatment. Col with highest photoprotection of light absorption capacity had highest resistance to HL among the three lines. The line ans with high antioxidant capacity could not compensate for its disadvantages in HL caused by the absence of the light-shielding function of anthocyanins. In addition, the expression level of the Anthocyanin Synthase (ANS) gene was most upregulated after HL treatment, suggesting that the conversion of colorless into colored anthocyanin precursors was necessary under HL. The contribution of anthocyanins to flavonoids, phenols, and antioxidant capacity increased in the late period of HL, suggesting that plants prefer to synthesize red anthocyanins (a group of colored antioxidants) over other colorless antioxidants to cope with HL. These experimental observations indicate that the light attenuation role of anthocyanins is more important than their antioxidant role in photoprotection.Background The most common etiology of colovesical fistulas is complicated diverticular disease and the treatment of choice is surgical resection. There are very few reports of the application of minimally invasive approaches for these surgeries. The aim of our study was to evaluate the role of laparoscopy in this challenging surgical setting. Methods A retrospective analysis of patients who underwent transabdominal surgery for colovesical fistula in 2008-2018 was performed. Patients were divided into 2 groups patients who had open surgery and patients treated with laparoscopy. The postoperative course was reviewed for the length of stay, postoperative complications, readmission, emergency re-operation, and mortality RESULTS Thirty-five patients were included (13 females [37%]; median age 68 [range 28-84] years) with a mean body mass index of 29 ± 7.19 kg/m2. The main fistula etiology was diverticulitis (91%). Seventeen patients (48.5%) had laparoscopic surgery and 2 patients in whom laparoscopy was attempted underwent conversion to laparotomy. The benefits of laparoscopy included significant reductions in morbidity including surgical site infections and medical complications following laparoscopy. Conclusions Laparoscopic management of colovesical fistula is both safe and feasible in a high volume laparoscopic colorectal surgery center. Laparoscopy offers potential benefits including a decreased incidence of surgical site infections and medical complications.Longitudinal myocardial strain is considered to deteriorate in the early ischemic stage compared to circumferential and radial strains because the subendocardial inner oblique fibers are generally directed along the longitudinal axis. However, it is unclear whether the decrease in longitudinal strain precedes a decrease in circumferential and radial strains during acute coronary flow reduction. The left anterior descending artery was gradually narrowed in 13 open-chest dogs. Whole-wall and subendocardial longitudinal, circumferential, and radial strains were analyzed at baseline and during flow reduction. Peak systolic and end-systolic strains, the postsystolic strain index (PSI), and the early systolic strain index (ESI) were measured in the risk area; the decreasing rate in each parameter and the diagnostic accuracy to detect flow reduction were evaluated. Absolute values of peak systolic and end-systolic strains gradually decreased with flow reduction. The decreasing rate and diagnostic accuracy of longitudinal systolic strain were not significantly different from those in other strains, although the diagnostic accuracy of radial systolic strain tended to be lower. PSI and ESI gradually increased with flow reduction. In these parameters, a lower diagnostic accuracy with respect to radial strain was not demonstrated. During acute coronary flow reduction, the decrease in longitudinal systolic strain did not precede that in circumferential systolic strain; however, the decrease in radial systolic strain may be smaller than that of other systolic strains. In contrast, there appeared to be no differences in the PSI and ESI values among the three strains.Noninvasive estimation of systolic pulmonary artery pressure (SPAP) during exercise stress echocardiography (ESE) is recommended for pulmonary hemodynamics evaluation but remains flow-dependent. Our aim was to assess the feasibility of pulmonary vascular reserve index (PVRI) estimation during ESE combining SPAP with cardiac output (CO) or exercise-time and compare its value in three group of patients with invasively confirmed pulmonary hypertension (PH), at risk of PH development (PH risk) mainly with systemic sclerosis and in controls (C) without clinical risk factors for PH, age-matched with PH risk patients. We performed semisupine ESE in 171 subjects 31 PH, 61 PH at risk and 50 controls as well as in 29 young, healthy normals. Rest and stress assessment included tricuspid regurgitant flow velocity (TRV), pulmonary acceleration time (ACT), CO (Doppler-estimated). selleck chemical SPAP was calculated from TRV or ACT when TRV was not available. We estimated PVRI based on CO (peak CO/SPAP*0.1) or exercise-time (ESE time/SPAP*0.1). During stress, TRV was measurable in 44% patients ACT in 77%, either one in 95%. PVRI was feasible in 65% subjects with CO and 95% with exercise-time (p less then 0.0001). PVRI was lower in PH compared to controls both for CO-based PVRI (group 1 = 1.0 ± 0.95 vs group 3 = 4.28 ± 2.3, p less then 0.0001) or time-based PVRI estimation (0.66 ± 0.39 vs 3.95 ± 2.26, p less then 0.0001). The proposed criteria for PH detection were for CO-based PVRI ≤ 1.29 and ESE-time based PVRI ≤ 1.0 and for PH risk ≤ 1.9 and ≤ 1.7 respectively. Noninvasive estimation of PVRI can be obtained in near all patients during ESE, without contrast administration, integrating TRV with ACT for SPAP assessment and using exercise time as a proxy of CO. These indices allow for comparison of pulmonary vascular dynamics in patients with varied exercise tolerance and clinical status.
