Functional gastrointestinal disorders (FGIDs) encompass a range of complex conditions with similar clinical characteristics and no overt pathology. Recent recognition of sub-clinical pathologies in FGIDs, in conjunction with physiological and biochemical abnormalities including increased intestinal permeability, microbial profile alterations, differences in metabolites and extra-intestinal manifestations of disease, call into question the designation of these conditions as 'functional'. This is despite significant heterogeneity in both symptom profile and specifics of reported physiological abnormalities hampering efforts to determine defined mechanisms that drive onset and chronicity of symptoms. Instead, the literature demonstrates these conditions are disorders of homeostatic imbalance, with disruptions in both host and microbial function and metabolism. This imbalance is also associated with extraintestinal abnormalities including psychological comorbidities and fatigue that may be a consequence of gastrointestinal disruption. Given the exploitation of such abnormalities will be crucial for improved therapeutic selection, an enhanced understanding of the relationship between alterations in function of the gastrointestinal tract and the response of the immune system is of interest in identifying mechanisms that drive FGID onset and chronicity. Considerations for future research should include the role of sex hormones in regulating physiological functions and treatment responses in patients, as well as the importance of high-level phenotyping of clinical, immune, microbial and physiological parameters in study cohorts. There is opportunity to examine the functional contribution of the microbiota and associated metabolites as a source of mechanistic insight and targets for therapeutic modulation.
Laparoscopic permanent contraception was previously accomplished most commonly using tubal occlusion procedures. Bilateral salpingectomy (BS) has recently been introduced as an alternative due to possibly superior contraception and greater protection against ovarian cancer.

The aim of this study is to assess uptake, feasibility and perioperative outcomes of laparoscopic BS as an alternative to tubal occlusion in Australia.

A retrospective review of permanent female contraception at two Australian hospitals from January 2014 through December 2020 was performed. The primary outcome was the uptake of BS. Secondary outcomes were feasibility, procedure length, number of ports, perioperative complications and admission length.

A total of 414 women were included; 92 (22.2%) underwent BS and 322 (77.8%) underwent tubal occlusion. There was a slow uptake of BS from 2014 to 2016 (0-3.2%), with a steep uptake from 2017 to 2020 (30-72%) (P=0.001). Procedure feasibility was 96.8% (62/64) and 99.3% (282/284) for BS and tubal occlusion group, respectively (P=0.64). BS procedure time was longer by 23min (P<0.001). Three or more surgical ports were used in all cases of BS compared to 4.5% of the tubal occlusion group (P<0.001). There were no intraoperative complications. There were nine and six postoperative complications in the tubal occlusion versus BS group, respectively (P=0.10). The median admission length was 7.1 (tubal occlusion) versus 7.3 (BS) h (P=0.10), with five unintended overnight admissions.

BS is an increasing choice for permanent contraception. It appears equally feasible as tubal occlusion but typically requires a longer procedure time and a minimum of three surgical ports.

Immune checkpoint inhibitors (ICIs) have shown significant improvements in patients with advanced non-small cell lung cancer (NSCLC). One of the major issues with ICIs is determining the optimal treatment duration.

This multicenter, retrospective study analyzed clinical outcomes in patients with NSCLC who completed 2 years of ICI therapy or were treated for more than 6 months and then discontinued ICIs without disease progression at 11 medical centers in Korea between August 2017 and December 2020.

Ninety-six patients who completed 2 years of ICIs were reviewed. The median durations of treatment and follow-up were 24.0 and 33.9 months, respectively. The objective response rate (ORR) was 85.4%. The median progression-free survival (PFS) and overall survival (OS) periods were not reached. After completion, the PFS and OS rates were 81.1% and 96.4%, respectively, at 12 months. Forty-three patients were identified who discontinued ICIs without disease progression 26 (60.5%) for adverse events and 17 (39.5%) addition, even if ICIs are discontinued after 6 months in patients without disease progression, they may achieve a durable response and facilitate long-term survival.
The optimal treatment duration for immune checkpoint inhibitors (ICIs) remains to be determined. This study reports the long-term outcomes of patients with non-small cell lung cancer who completed 2 years of ICI therapy or achieved a durable response after the discontinuation of ICIs without disease progression in real-world practice. A significantly high proportion of patients who completed 2 years of ICIs continued to experience long-term progression-free survival. In addition, even if ICIs are discontinued after 6 months in patients without disease progression, they may achieve a durable response and facilitate long-term survival.Can children exploit knowledge asymmetries to get away with selfishness? This question was addressed by testing 6- to 9-year-old children (N = 164; 81 girls) from the Northeastern United States in a modified Ultimatum Game. Children were assigned to the roles of proposers (who offered some proportion of an endowment) and responders (who could accept or reject offers). Both players in the Informed condition knew the endowment quantity in each trial. However, in the Uninformed condition, only proposers knew this information. In this condition, many proposers made "strategically selfish" offers that seemed fair based on the responders' incomplete knowledge but were actually highly selfish. These results indicate that even young children possess the ability to deceive others about their selfishness.The regulation and defense of intracellular pH is essential for homeostasis. Indeed, alterations in cerebrovascular acid-base balance directly affect cerebral blood flow (CBF) which has implications for human health and disease. BRD7389 datasheet For example, changes in CBF regulation during acid-base disturbances are evident in conditions such as chronic obstructive pulmonary disease and diabetic ketoacidosis. The classic experimental studies from the past 75+ years are utilized to describe the integrative relationships between CBF, carbon dioxide tension (PCO2 ), bicarbonate (HCO3 - ), and pH. These factors interact to influence 1) the time course of acid-base compensatory changes and the respective cerebrovascular responses (due to rapid exchange kinetics between arterial, extracellular fluid, and intracellular brain tissue). We propose that alterations in arterial [HCO3 - ] during acute respiratory acidosis/alkalosis contribute to cerebrovascular acid-base regulation; and 2) the regulation of CBF by direct changes in arterial versus extravascular/ interstitial PCO2 and pH - the latter recognized as the proximal compartment which alters vascular smooth muscle cell regulation of CBF. Taken together, these results substantiate two key ideas first, that the regulation of CBF is affected by the severity of metabolic/respiratory disturbances, including the extent of partial/full acid-base compensation. Second, that the regulation of CBF is independent of arterial pH and that diffusion of CO2 across the blood-brain barrier is integral to altering perivascular extracellular pH. Overall, by realizing the integrative relationships between CBF, PCO2 , HCO3 - , and pH, experimental studies may provide insights to improve CBF regulation in clinical practice with treatment of systemic acid-base disorders.

We sought to determine which combination of clinical and electroencephalography (EEG) characteristics differentiate between an antiseizure medication (ASM)-resistant vs ASM-responsive outcome for patients with idiopathic generalized epilepsy (IGE).

This was a case-control study of ASM-resistant cases and ASM-responsive controls with IGE treated at five epilepsy centers in the United States and Australia between 2002 and 2018. We recorded clinical characteristics and findings from the first available EEG study for each patient. We then compared characteristics of cases vs controls using multivariable logistic regression to develop a predictive model of ASM-resistant IGE.

We identified 118 ASM-resistant cases and 114 ASM-responsive controls with IGE. First, we confirmed our recent finding that catamenial epilepsy is associated with ASM-resistant IGE (odds ratio [OR] 3.53, 95% confidence interval [CI] 1.32-10.41, for all study subjects) after covariate adjustment. Other independent factors seen with ASM ree additional predictive value.
Multiple clinical and EEG characteristics independently predict ASM resistance in IGE. To improve understanding of a patient's prognosis, clinicians could consider asking about specific seizure-type combinations and track whether they experience catamenial epilepsy. Obtaining prolonged EEG studies to record the burden of GSWs in sleep and assessing for the presence of GPTs may provide additional predictive value.
Partial agonists of the nociceptin opioid peptide (NOP) receptor have potential therapeutic use as antihypertensive and water diuretic (aquaretic) agents. However, to date, peptide NOP receptor ligands have failed to progress in clinical trials due to poor pharmacokinetics and adverse effects. Non-peptide, small-molecule NOP receptor ligands may be more suitable as therapeutic agents. Therefore, this study investigated the cardiovascular and renal responses produced by the novel non-peptide NOP receptor agonists AT-403, AT-090, AT-127, and AT-039.

Changes in mean arterial pressure (MAP), heart rate (HR), renal excretory function, and occurrence of sedation and hyperphagia were determined before and after intravenous (i.v.) bolus injection or infusion of the NOP agonists in conscious Sprague-Dawley rats. Additional studies involving (i) measurement of renal sympathetic nerve activity (RSNA) and (ii) renal denervation were conducted to investigate the role of the renal nerves in the cardiorenal responses to AT-039.

I.v. bolus injection of AT-403, AT-090, AT-127, and AT-039 produced significant decreases in MAP and HR and a sodium-sparing diuresis. AT-403, AT-090, AT-127, but not AT-039, induced sedation and hyperphagia at all doses tested. I.v. infusion of AT-039 produced hypotension and aquaresis without adverse CNS effects or change inHR, responses that were also observed in renal denervated rats.

Non-peptide NOP agonists decrease blood pressure and produce aquaresis in conscious rodents. Due to lack of sedation and hyperphagia, AT-039 represents a novel NOP agonist that may be useful for treatment of hypertension and/or volume overload/hyponatremic states.
