High quality data on efficacy of L-Ornithine L-Aspartate (LOLA) in cirrhotics with bouts of overt hepatic encephalopathy (OHE) is missing. We aimed to evaluate the efficacy of intravenous LOLA in reversal of bouts of OHE in cirrhotics. In this prospective double-blind randomized placebo controlled trial conducted at two tertiary care institutes in India, 370 cirrhotics with bouts of OHE were screened. After exclusion, 193 (52.16%) patients were randomized to receive either intravenous infusions of LOLA (n=98), 30 grams daily or Placebo (n=95) for 5 days...

Objective In Stiff-Person Syndrome (SPS), an antibody-mediated impaired GABAergic neurotransmission is believed to cause muscle stiffness and spasms. Patients improve with GABA-enhancing drugs and IVIg, but several respond poorly and remain disabled. The need for more effective therapy prompted a trial with the anti-CD20 monoclonal antibody rituximab. Methods This was a placebo-controlled randomized trial of rituximab (two bi-weekly infusions of 1gr each). The primary outcome was a change in stiffness scores at 6 months...

Monitoring voltage dynamics in defined neurons deep in the brain is critical for unraveling the function of neuronal circuits, but is challenging due to the limited performance of existing tools. In particular, while genetically encoded voltage indicators have shown promise for optical detection of voltage transients, many indicators exhibit low sensitivity when imaged under two-photon illumination. Previous studies thus fell short of visualizing voltage dynamics in individual neurons in single trials. Here, we report ASAP2s, a novel voltage indicator with improved sensitivity...

Recent research supports a favorable role of cranberries on cardiometabolic health. Postprandial metabolism, especially hyperglycemia, has been shown to be an independent cardiovascular risk and few clinical studies have reported the role of berries in improving postprandial dysmetabolism. We investigated the postprandial effects of dried cranberries following a high-fat breakfast challenge in obese participants with type 2 diabetes (T2DM), in a randomized crossover trial. Blood draw and vascular measurements were conducted at fasting, 1, 2 and 4 hours (h), following the consumption of a fast-food style high-fat breakfast (70 g fat, 974 kcal) with or without cranberries (40 g)...

BACKGROUND: Quantifying hypoglycemia has traditionally been limited to using the frequency of hypoglycemic events during a given time interval using data from blood glucose (BG) testing. However, continuous glucose monitoring (CGM) captures three parameters-a Hypo-Triad-unavailable with BG monitoring that can be used to better characterize hypoglycemia: area under the curve (AUC), time (duration of hypoglycemia), and frequency of daily episodes below a specified threshold. METHODS: We developed two new analytic metrics to enhance the traditional Hypo-Triad of CGM-derived data to more effectively capture the intensity of hypoglycemia (IntHypo) and overall hypoglycemic environment called the "hypoglycemia risk volume" (HypoRV)...

Observational analyses for causal inference often rely on real world data collected for purposes other than research. A frequent goal of these observational analyses is to use the data to emulate a hypothetical randomized experiment, i.e., the target trial, that mimics the design features of a true experiment, including a clear definition of time zero with synchronization of treatment assignment and determination of eligibility. We review a recent observational analysis that explicitly emulated a target trial of screening colonoscopy using insurance claims from U...

AIMS: Results with GLP1-receptor agonists (GLP-1RA) on microvascular complications of diabetes are contrasting. In trials designed for cardiovascular outcomes, both liraglutide and semaglutide were associated with a relevant reduction in the incidence and progression of nephropathy. On the other hand, in the same trials, semaglutide was associated with an increased progression of retinopathy, and a similar trend was observed for liraglutide. This meta-analysis is aimed at assessing the effects of GLP-1RA on retinopathy and nephropathy...

Delayed language development may be an early indicator of autism spectrum disorder (ASD). Early intervention is critical for children with ASD, and the present study presents pilot data on a clinical trial of omega-3 and -6 fatty acid supplementation and language development, a secondary trial outcome, in children at risk for ASD. We randomized 31 children to receive an omega-3 and -6 supplement or a placebo for 3 months, and measured their language abilities at baseline and after supplementation. Gesture use, but not word production, increased for children in the treatment group more than children in the placebo group...
