A carrier-free nanovaccine combined with cancer immunotherapy overcomes gemcitabine resistance.

Drug resistance is a significant challenge in cancer chemotherapy and is a primary factor contributing to poor recovery for cancer patients. Although drug-loaded nanoparticles have shown promise in overcoming chemotherapy resistance, they often carry a combination of drugs and require advanced design and manufacturing processes. Furthermore, they seldom approach chemotherapy-resistant tumors from an immunotherapy perspective. In this study, we developed a therapeutic nanovaccine composed solely of chemotherapy-induced resistant tumor antigens (CIRTAs) and the immune adjuvant Toll-like receptor (TLR) 7/8 agonist R848 (CIRTAs@R848). This nanovaccine does not require additional carriers and has a simple production process. It efficiently delivers antigens and immune stimulants to dendritic cells (DCs) simultaneously, promoting DCs maturation. CIRTAs@R848 demonstrated significant tumor suppression, particularly when used in combination with the immune checkpoint blockade (ICB) anti-PD-1 (αPD-1). The combined therapy increased the infiltration of T cells into the tumor while decreasing the proportion of regulatory T cells (Tregs) and modulating the tumor microenvironment, resulting in long-term immune memory. Overall, this study introduces an innovative strategy for treating chemotherapy-resistant tumors from a novel perspective, with potential applications in personalized immunotherapy and precision medicine.

Chemistry/structural biology of psychedelic drugs and their receptor(s).

This brief review highlights some of the structure-activity relationships of classic serotonergic psychedelics. In particular, we discuss structural features of three chemotypes: phenethylamines, ergolines and certain tryptamines, which possess psychedelic activity in humans. Where they are known, we point out the underlying molecular mechanisms utilized by each of the three chemotypes of psychedelic molecules. With a focus on the 5-HT2A receptor subtype, a G-protein coupled receptor known to be the primary target of psychedelics, we refer to several X-ray and cryoEM structures, with a variety of ligands bound, to illustrate the underlying atomistic basis for some of the known pharmacological observations of psychedelic drug actions.

Peroxisome proliferator-activated receptor agonists: A new hope towards the management of alcoholic liver disease.

In this editorial, we examine a paper by Koizumi et al, on the role of peroxisome proliferator-activated receptor (PPAR) agonists in alcoholic liver disease (ALD). The study determined whether elafibranor protected the intestinal barrier and reduced liver fibrosis in a mouse model of ALD. The study also underlines the role of PPARs in intestinal barrier function and lipid homeostasis, which are both affected by ALD. Effective therapies are necessary for ALD because it is a critical health issue that affects people worldwide. This editorial analyzes the possibility of PPAR agonists as treatments for ALD. As key factors of inflammation and metabolism, PPARs offer multiple methods for managing the complex etiology of ALD. We assess the abilities of PPARα, PPARγ, and PPARß/δ agonists to prevent steatosis, inflammation, and fibrosis due to liver diseases. Recent research carried out in preclinical and clinical settings has shown that PPAR agonists can reduce the severity of liver disease. This editorial discusses the data analyzed and the obstacles, advantages, and mechanisms of action of PPAR agonists for ALD. Further research is needed to understand the efficacy, safety, and mechanisms of PPAR agonists for treating ALD.

Glucagon-like peptide-1 receptor agonists: Exploring the mechanisms from glycemic control to treatment of multisystemic diseases.

This editorial takes a deeper look at the insights provided by Soresi and Giannitrapani, which examined the therapeutic potential of glucagon-like peptide-1 receptor agonists (GLP-1RAs) for metabolic dysfunction-associated fatty liver disease. We provide supplementary insights to their research, highlighting the broader systemic implications of GLP-1RAs, synthesizing the current understanding of their mechanisms and the trajectory of research in this field. GLP-1RAs are revolutionizing the treatment of type 2 diabetes mellitus and beyond. Beyond glycemic control, GLP-1RAs demonstrate cardiovascular and renal protective effects, offering potential in managing diabetic kidney disease al-ongside renin-angiotensin-aldosterone system inhibitors. Their role in bone metabolism hints at benefits for diabetic osteoporosis, while the neuroprotective properties of GLP-1RAs show promise in Alzheimer's disease treatment by modulating neuronal insulin signaling. Additionally, they improve hormonal and metabolic profiles in polycystic ovary syndrome. This editorial highlights the multifaceted mechanisms of GLP-1RAs, emphasizing the need for ongoing research to fully realize their therapeutic potential across a range of multisystemic diseases.

Activation of polycystin-1 signaling by binding of stalk-derived peptide agonists.

Polycystin-1 (PC1) is the protein product of the PKD1 gene whose mutation causes autosomal dominant Polycystic Kidney Disease (ADPKD). PC1 is an atypical G protein-coupled receptor (GPCR) with an autocatalytic GAIN domain that cleaves PC1 into extracellular N-terminal and membrane-embedded C-terminal (CTF) fragments. Recently, activation of PC1 CTF signaling was shown to be regulated by a stalk tethered agonist (TA), resembling the mechanism observed for adhesion GPCRs. Here, synthetic peptides of the first 9- (p9), 17- (p17), and 21-residues (p21) of the PC1 stalk TA were shown to re-activate signaling by a stalkless CTF mutant in human cell culture assays. Novel Peptide Gaussian accelerated molecular dynamics (Pep-GaMD) simulations elucidated binding conformations of p9, p17, and p21 and revealed multiple specific binding regions to the stalkless CTF. Peptide agonists binding to the TOP domain of PC1 induced close TOP-putative pore loop interactions, a characteristic feature of stalk TA-mediated PC1 CTF activation. Additional sequence coevolution analyses showed the peptide binding regions were consistent with covarying residue pairs identified between the TOP domain and the stalk TA. These insights into the structural dynamic mechanism of PC1 activation by TA peptide agonists provide an in-depth understanding that will facilitate the development of therapeutics targeting PC1 for ADPKD treatment.

Efficacy of Different Doses and Forms of the GLP-1 Receptor Agonist Semaglutide in Weight Reduction Among Non-diabetic Obese or Overweight Populations.

Disorders linked to increased body weight are on the rise and obesity is a global epidemic associated with a rising risk for developing comorbidities, such as hypertension or type 2 diabetes. There is a significant need to develop a multimodal approach targeting obesity within clinical medicine. Pharmacological options to produce weight loss have been a popular research area and the novel glucagon-like Peptide-1 receptor agonists (GLP-1 RA) are highly effective glycemic control agents that have shown a substantial weight loss effect. This systematic review explores the efficacy of semaglutide, a GLP-1 RA agent, in a non-diabetic population, looking at endpoints of changes in weight and waist circumference and the percentage of patients achieving a clinically effective weight loss of at least 5%. This study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guidelines. A comprehensive search was undertaken to find applicable papers using three databases, including PubMed, PubMed Central, and Cochrane Library. The included articles were narrowed down from an initial pool of 423 papers using filters, automation tools, inclusion/exclusion criteria, and quality appraisal tools. In this systematic review, we have analyzed 10 high-quality studies published in the last five years, including nine randomized control trials (RCTs) and a retrospective cohort study. The aim was to combine the results of these studies, encompassing 6623 participants, to showcase the effectiveness of GLP-1 RAs in the non-diabetic obese or overweight population. The consolidated data from the literature in this systematic review endorses the use of semaglutide as a highly efficient weight-reducing agent, contributing positive insight to both clinicians and researchers in the field of obesity treatment.

Dopamine D2 receptor partial agonists in the treatment of schizophrenia -example of brexpiprazole. / Czesciowi agonisci receptora dopaminowego D2 w leczeniu schizofrenii -przyklad brekspiprazolu.

Since the 1950s, there have been rapid developments in psychiatric pharmacotherapy, resulting not only in more effective treatment of patients, but also in improvements in minimizing adverse effects of therapy. Modern third-generation antipsychotics, in addition to antagonism toward D2 receptors, also exhibit partial agonism toward dopamine receptors. Such a mechanism of action is intended to regulate dopaminergic transmission - inhibit (antagonism) it in pathways where it is excessive (excessive transmission in the mesolimbic pathway in psychotic patients, excessive transmission in the tuberoinfundibular pathway in patients with hyperprolactinemia) and stimulate (agonism) it in pathways where it is too low (mesocortical pathway). This has a beneficial effect on both the reduction of adverse symptoms and the negative, affective and cognitive symptoms of patients suffering from schizophrenia. The purpose of this review article is to present the most important clinical aspects of the use of dopamine D2 receptor partial agonists in the treatment of schizophrenia, using brexpiprazole as an example, and to define the profile of patients to whom this drug could be dedicated - based on recent studies.

Causal relationship between novel antidiabetic drugs and ischemic stroke: a drug-targeted Mendelian randomization study.

Background: The escalating global economic burden of ischemic stroke poses a significant public health challenge amid global aging trends. The broad therapeutic efficacy of new antidiabetic drugs may offer new options in the prevention and treatment of ischemic stroke. Consistent conclusions regarding the relationship between novel antidiabetic agents and the risk of ischemic stroke remain elusive, and the causal relationship deserves further investigation. Materials and methods: Three novel antidiabetic drug targets were selected, and cis-expression quantitative trait loci (cis-eQTL) were screened as instrumental variables. Genetic association data for ischemic stroke were obtained from the Genome-wide Association Study (GWAS) database. Mendelian randomization (MR) analysis, facilitated by R software, calculated MR estimates for each single nucleotide polymorphism (SNP), and meta-analysis was performed using five methods. To ensure robustness, sensitivity analyses, heterogeneity analyses, horizontal pleiotropy analyses, and co-localization analyses were conducted for significant MR associations. Results: Three eQTLs for antidiabetic drug genes served as instrumental variables, utilizing a GWAS dataset comprising 34,217 cases and 406,111 controls for ischemic stroke. Genetic variants in glucagon-like peptide-1 receptor agonists (GLP-1 RA) targets exhibited a positive correlation with ischemic stroke risk (OR 1.06, 95% CI 1.04-1.08, P = 0.000), while genetic variation in dipeptidyl peptidase 4 inhibitors (DPP-4i) targets showed a negative association with ischemic stroke risk (OR 0.93, 95% CI 0.89-0.97, P = 0.003). Sensitivity analyses supported robust conclusions, revealing no heterogeneity or horizontal pleiotropy. Conclusion: This study found that GLP-1 RA and DPP-4i were associated with an increased risk of ischemic stroke by MR analysis. Although sensitivity analyses provide support for this result, it contradicts previous knowledge. Therefore, the results of this study still need to treated with caution. Updated and more in-depth GWAS data and high-quality real-world data are expected to validate the results.

Protocol for a Series of Systematic Reviews and Network Meta-analyses of Randomized Controlled Trials of Medications for Patients with Overactive Bladder Symptoms.

Multiple randomized controlled trials (RCTs) have examined first-line pharmacological agents such as anticholinergics and ß3 agonists for the management of overactive bladder symptoms (OAB). Although earlier systematic reviews and (network) meta-analyses aimed to summarize the evidence, a substantial number of trials were not included, so a comprehensive and methodologically rigorous evaluation of the comparative effectiveness of all first-line pharmacological treatments is lacking. We aim to conduct a series of systematic reviews and network meta-analyses (NMAs) for a comprehensive assessment of the effectiveness and safety of first-line pharmacological treatments for OAB. Eligible studies will include RCTs comparing anticholinergics and ß3 agonists to one another or to placebo in adults with OAB or detrusor overactivity. Pairs of reviewers with methodological training will independently evaluate candidate studies to determine eligibility and extract relevant data. We will incorporate patient-important outcomes, including urinary urgency episodes, urgency incontinence episodes, any type of incontinence episodes, urinary frequency, nocturia, and adverse events. We will conduct the NMAs using a frequentist framework and a graph theory model for each outcome. Analysis will follow rigorous methodologies, including handling of missing data and assessment of the risk of bias. We will conduct sensitivity and subgroup analyses and will apply the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach to rate evidence certainty. Our approach aims to address the knowledge gap in the treatment of OAB by synthesizing evidence from RCTs worldwide. We will employ robust statistical methods, including frequentist NMA, to general clinically relevant and patient-important insights. Sensitivity and subgroup analyses will enhance the robustness and generalizability of our findings. Our reviews strive to inform evidence-based decisions in the management of OAB, to ultimate improve patient outcomes. Our study results may guide health policy decisions, such as reimbursement policies, and future studies in functional urology. The protocol for the review series is registered on PROSPERO as CRD42023266915.

Inflammatory proteins associated with Alzheimer's disease reduced by a GLP1 receptor agonist: a post hoc analysis of the EXSCEL randomized placebo controlled trial.

BACKGROUND: Glucagon-like peptide-1 receptor agonists are a viable option for the prevention of Alzheimer's disease (AD) but the mechanisms of this potential disease modifying action are unclear. We investigated the effects of once-weekly exenatide (EQW) on AD associated proteomic clusters. METHODS: The Exenatide Study of Cardiovascular Event Lowering study compared the cardiovascular effects of EQW 2 mg with placebo in 13,752 people with type 2 diabetes mellitus. 4,979 proteins were measured (Somascan V0.4) on baseline and 1-year plasma samples of 3,973 participants. C-reactive protein (CRP), ficolin-2 (FCN2), plasminogen activator inhibitor 1 (PAI-1), soluble vascular cell adhesion protein 1 (sVCAM1) and 4 protein clusters were tested in multivariable mixed models. RESULTS: EQW affected FCN2 (Cohen's d -0.019), PAI-1 (Cohen's d -0.033), sVCAM-1 (Cohen's d 0.035) and a cytokine-cytokine cluster (Cohen's d 0.037) significantly compared with placebo. These effects were sustained in individuals over the age of 65 but not in those under 65. CONCLUSIONS: EQW treatment was associated with significant change in inflammatory proteins associated with AD. TRIAL REGISTRATION: EXSCEL is registered on ClinicalTrials.gov: NCT01144338 on 10th of June 2010.

Glucagon-like peptide-1 receptor agonists and kidney outcomes.

Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have gained increasing attention for their potential benefits in people with type 2 diabetes mellitus (T2DM) with chronic kidney disease (CKD). Most supportive evidence of a kidney-protective effect of the GLP-1RA class of medications has been derived from kidney-related outcomes reported from cardiovascular outcome trials (CVOTs). GLP-1RAs have been shown to reduce albuminuria, mitigate cardiovascular risk, and possibly attenuate estimated glomerular filtration rate (eGFR) decline. The kidney-protective effects of GLP-1RAs are thought to be attributed to their anti-inflammatory, antioxidant, and vasodilatory properties. Despite these promising findings, the use of GLP-RAs has yet to be definitively shown to slow progression to chronic kidney failure in people with T2DM. The Research Study to See How Semaglutide Works Compared to Placebo in People With Type 2 Diabetes and Chronic Kidney Disease (FLOW trial) is the first major trial assessing the potential of a GLP-1RA to slow progression of kidney disease in people with established CKD to clinically important kidney end points. On March 5, 2024, the top line result from FLOW was announced with semaglutide 1.0 mg being reported to reduce the primary end point of the trial by a significant 24% compared with placebo. Here, we summarize the kidney outcomes reported from CVOTs for the GLP-1RA class of medication and briefly describe kidney outcomes from other major GLP-1RAs trials. We also discuss a potential role of the dual GLP-1/glucose-dependent insulinotropic polypeptide (GIP) receptor agonist, tirzepatide, as a kidney-protective agent.

Increased Cardiometabolic Risk in Men with Hypoprolactinemia: A Pilot Study.

Low prolactin levels in men predispose them to mood disturbances, sexual dysfunction, and diabetes. The purpose of the current study was to assess cardiometabolic risk in males with hypoprolactinemia. This prospective study included three age-matched groups of young and middle-aged men: individuals with cabergoline-induced hypoprolactinemia (n = 15), cabergoline-treated subjects with prolactin levels within the reference range (n = 20), and untreated men with normal prolactin levels (n = 31). In men with hypoprolactinemia, the cabergoline dose was reduced in order to normalize prolactin concentration. Anthropometric parameters, blood pressure, QRISK3 score; plasma concentrations of prolactin, glucose, insulin, lipids, uric acid, high-sensitivity C-reactive protein (hsCRP), fibrinogen, homocysteine, and testosterone; whole-blood levels of glycated hemoglobin (HbA1C); urinary albumin-to-creatinine ratio (UACR); and carotid intima-media thickness were assessed at baseline and six months later. Men with hypoprolactinemia were characterized by higher body mass index, fat content, waist circumference, systolic blood pressure, fasting and 2 h post-load glucose, HbA1C, HOMA1-IR, uric acid, hsCRP, fibrinogen, homocysteine, and UACR; by lower HDL cholesterol and testosterone; by greater intima-media thickness; and by a higher QRISK3 score than their peers with normal prolactin levels. There were no statistically significant differences in the measured parameters between both groups of men with normal prolactin levels. Normalization of prolactin concentration was accompanied by normalization of biochemical variables, systolic blood pressure, and QRISK3 score. Although cabergoline dose reduction did not cause statistically significant changes in the remaining anthropometric parameters and intima-media thickness, six months later, they did not differ from those observed in the remaining study groups. Our findings suggest that iatrogenic hypoprolactinemia is associated with increased cardiometabolic risk, which is reversible and resolves after the normalization of prolactin levels.

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) and suicidality: A replication study using reports to the World Health Organization pharmacovigilance database (VigiBase®).

INTRODUCTION: Reports of suicidality associated with glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have been reported to the European Medicines Agency (EMA) and the United States Food and Drug Administration (FDA). We previously reported an increased reporting odds ratio (ROR) of some measures of suicidality with semaglutide and liraglutide using the FDA Adverse Event Reporting System (FAERS). Notwithstanding the increased ROR, causality between GLP-1 RAs exposure and any aspect of suicidality is not established. RESEARCH DESIGN AND METHODS: The analysis herein aims to extend a previous analysis of the FAERS by evaluating the ROR for suicidality reported to the World Health Organization (WHO) Pharmacovigilance Database (VigiBase). We aimed to characterize the ROR of suicidality associated with GLP-1 RAs, as extrapolated from spontaneous reports. As per our previous report, the ROR was considered significant when the lower limit of the 95 % confidence (CI) was >1.0. RESULTS: We searched VigiBase reports from inception to January 2024. The RORs for suicidal ideation were significantly increased for semaglutide (5.82), liraglutide (4.03) and tirzepatide (2.25). For "depression/suicidal", the ROR was significantly increased for semaglutide (14.74) and liraglutide (5.86); and for suicidal behaviour, the ROR was significantly increased for semaglutide (6.52) and liraglutide (3.90). However, for suicide attempts, the ROR was significantly decreased for semaglutide (0.11), dulaglutide (0.075), exenatide (0.047) and liraglutide (0.15). For completed suicide, the ROR was also significantly decreased for semaglutide (0.01), dulaglutide (0.003), exenatide (0.002) and liraglutide (0.008). CONCLUSION: Unlike our previous report with FAERS, a mixed pattern of ROR emerged in the WHO VigiBase with respect to suicidality and exposure to select GLP-RAs. Causation between GLP-1 RA exposure and suicidality (either increased or decreased) cannot be ascertained from ROR data.

Sedation and general anaesthesia of crocodilians: a systematic review.

Sedation and general anaesthesia of crocodilians pose unique challenges due to their aggressive nature, poikilothermic physiology, and specific anatomical and physiological characteristics, all factors that complicate crocodilian anaesthesia. This review aimed to systematically review the literature regarding sedation and general anaesthesia of crocodilians with focus on efficacy and impact on vital parameters. A systematic literature search was performed according to PRISMA guidelines on May 2, 2023 in the databases Embase, PubMed, Scopus and Web of Science. Publications were excluded based on predefined exclusion criteria, which encompassed non-standard publications and publications unrelated to crocodilians, with fewer than five animals and/or with insufficient data on sedation and general anaesthesia. Five key factors were used to evaluate the strength of evidence: number of included animals, study design, definition of recovery time, blinded assessment of recovery and conflict of interest. Ten publications were included in this systematic review. Drugs used included alpha-2-adrenoceptor agonists, dissociative anaesthetics, benzodiazepines, neuromuscular blocking agents, propofol, alfaxalone, and inhalant gasses. The studies included in total 55 Alligator mississippiensis, 110 Crocodylus porosus, 15 Crocodylus johnstoni, and 15 Crocodylus niloticus. Factors such as temperature, administration route, dose, species, and age influenced protocols for sedation and general anaesthesia of crocodilians. The studies included used five different study designs. Only one study included a control group, done on retrospectively collected data. Blinded recovery assessments and declarations of no conflict of interest were noted in some studies. The use of four distinct recovery definitions posed challenges to comparability in this systematic review. The studies reported that medetomidine provided stable and reversible sedation, although it depressed heart rate. Alfaxalone was less stable outside the optimal temperature range. Intubation and inhalation anaesthesia were effective, and adrenaline reduced the length of the recovery period. Overall, the review provides valuable insights for veterinarians, researchers, and wildlife professionals involved in sedation and general anaesthesia of the crocodilian species, however, the literature is limited, and further research is needed to improve evidence-based medical management.

Use of Glucagon-Like Peptide-1 Receptor Agonists Does Not Increase the Risk of Cancer in Patients with Type 2 Diabetes Mellitus.

Background: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are increasingly used for the treatment of type 2 diabetes mellitus (T2DM) given their extra-pancreatic effects. However, there are concerns about carcinogenesis in the pancreas and thyroid gland. We aimed to evaluate the site-specific incidence of cancer in patients with T2DM-treated GLP-1 RAs using a nationwide cohort. Methods: This study included data obtained from the Korean National Health Insurance Service (between 2004 and 2021). The primary outcome was newly diagnosed cancer, and the median follow-up duration for all participants was 8 years. Results: After propensity score matching, 7,827 participants were analyzed; 2,609 individuals each were included in the GLP-1 RA, diabetes mellitus (DM) control, and non-DM control groups. The incidence rate ratio (IRR) of subsequent cancer in patients with T2DM was 1.73, which was higher than that of individuals without DM, and it increased in both men and women. Analysis of patients with T2DM showed no increased cancer risk associated with the use of GLP-1 RA, and similar results were observed in both men and women. The IRRs of pancreatic cancer (0.74), thyroid cancer (1.32), and medullary thyroid cancer (0.34) did not significantly increase in the GLP-1 RA group compared with those in the DM control group. Conclusion: There was a 73% higher risk of cancer in patients with T2DM compared with the general population. However, among patients with T2DM, there was no association between the use of GLP-1 RAs and new-onset cancers, including pancreatic and medullary thyroid cancers.

Effects of glucagon-like peptide-1 receptor agonists on cardiovascular outcomes in high-risk type 2 diabetes: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been shown to provide cardiovascular benefits in patients with type 2 diabetes mellitus (T2DM). However, their cardiovascular protective efficacy in high-risk T2DM patients, particularly those with a history of cardiovascular events or severe chronic kidney disease, remains uncertain. METHODS: A comprehensive search was conducted in PubMed, Embase, Web of Science, and The Cochrane Library to identify randomized controlled trials (RCTs) that evaluated the effects of GLP-1 RAs on cardiovascular outcomes in high-risk patients with T2DM. A random-effects model was used to calculate pooled hazard ratios (HRs) for cardiovascular outcomes. Subgroup analyses and GRADE assessment were also performed. RESULTS: Nine RCTs involving 63,613 patients were included. GLP-1 RAs significantly reduced the risk of the primary composite outcome (HR: 0.86, 95% CI: 0.80-0.92), cardiovascular death (HR: 0.85, 95% CI: 0.78-0.93), all-cause death (HR: 0.87, 95% CI: 0.82-0.93), myocardial infarction (HR: 0.90, 95% CI: 0.82-0.98), stroke (HR: 0.85, 95% CI: 0.77-0.95), and heart failure (HF) hospitalization (HR: 0.90, 95% CI: 0.83-0.97). No significant difference in unstable angina (UA) hospitalization was observed (HR: 1.04, 95% CI: 0.95-1.15). Subgroup analyses indicated greater benefits with combination therapy, particularly in patients with chronic kidney disease. The quality of evidence was rated as "High" for six outcomes and "Moderate" for UA hospitalization. CONCLUSIONS: GLP-1 RAs significantly reduce cardiovascular risk in high-risk T2DM patients, especially with combination therapy and in those with chronic kidney disease. However, further research is needed to confirm their long-term effects.

Primary healthcare professionals' perceptions, attitudes and ideas regarding asthma management in Greece: A mixed-method study.

BACKGROUND: Implementing asthma guideline recommendations is challenging and there is variation between countries, and different healthcare professionals (HCPs). The International Primary Care Respiratory Group (IPCRG) has introduced the Asthma Right Care (ARC) programme implemented in 24 low, middle, and high countries, including Greece. It offers a promising approach drawn from social movements for health to improve asthma care by engaging HCPs in implementing guideline-based asthma care. OBJECTIVES: To explore HCPs' perspectives on current provision of asthma care and their willingness to improve implementation of recommended guidelines using ARC programme tools in Greece. METHODS: A mixed methods study conducted from September 2020 to April 2021. A convenience sample of 30 pharmacists, and 10 General Practitioners (GPs), responded to a questionnaire investigating perceptions, and attitudes, towards implementation of asthma guidelines. Then, a qualitative survey followed with semi-structured interviews to evaluate the feedback obtained from HCPs to assess the content, and applicability of the ARC tools. Data were analysed using thematic analysis. RESULTS: A range of practical challenges in implementing guideline-recommended interventions, improving asthma control and management were described by all HCPs, including lack of time and education, high workload, patients' perceptions, and poor communication contributing to poor management and inadequate follow-up of people with asthma. However, most HCPs were willing to use ARC interventions to improve guideline implementation. CONCLUSION: HCPs in Greece encounter challenges in implementing asthma guidelines; however, they can overcome these challenges by using ARC interventions and engagement tools to address barriers and implement efficient asthma management strategies.

There are data indicating unwarranted variation in asthma guideline implementation between healthcare professionals (HCPs) leading to avoidable harm.Understanding HCPs' and patients' perspectives of asthma control is essential to asthma management.HCPs can change their behaviour and improve clinical outcomes by utilising IPCRG Asthma Right Care interventions and engagement tools.

Perioperative Considerations for Patients on GLP1 Agonists.

GlP-1 receptor agonists are a class of medications that are becoming increasingly popular. Large trials have shown that their use provides reliable weight loss in obese patients and improved glycemic control in diabetic patients. Its use also has broader implications for overall metabolic health and has been shown to improve cardiovascular outcomes in high-risk populations. Glucagon-like peptide 1 receptors cause multiple effects in the body through stimulation of receptors expressed in a broad range of tissues including the pancreas, liver, gastrointestinal tract, kidneys, heart, endothelium, muscle, and brain. For the anesthesia professionals the effects of these medications on gastric emptying is important.

A cost-utility analysis of single maintenance and reliever (SMART) therapy as compared to step 3 fixed-dose therapy in patients aged 12 years or more with uncontrolled asthma.

OBJECTIVES: A significant percentage of patients with asthma appear to benefit from the addition of long-acting ß2-agonists (LABAs) to ICS to achieve better control of their disease. The aim of the present study was to determine the cost-utility of single inhaler combination inhaled ICS/LABAs as both maintenance and reliever (SMART) versus remaining at the same treatment step with fixed-dose ICS-LABA maintenance with a short-acting ß2-agonist (SABA) as reliever in patients aged 12 years or more with uncontrolled asthma. METHODS: A Markov-type model was developed to estimate the costs and health outcomes of a simulated cohort of patients aged 12 years or more with uncontrolled asthma treated for 12 months. The effectiveness data and transition probabilities were obtained from a recent meta-analysis. Cost data were obtained from official databases provided by the Colombian Ministry of Health. The main outcome was the variable "quality-adjusted life-years" (QALYs). RESULTS: The base-case analysis showed that compared with remaining at the same GINA treatment step with ICS/LABA maintenance plus SABA reliever, ICS/LABAs as SMART was associated with lower costs, US$2,906.92 versus $4,462.02 average cost per patient, and the greatest gain in QALYs, 0.8540 versus 0.8258 QALYs on average per patient, thus leading to dominance. CONCLUSIONS: Compared with remaining at the same GINA treatment step with ICS/LABA maintenance plus SABA reliever, ICS/LABAs as SMART is more cost-effective in patients aged 12 years or more with uncontrolled asthma. This is because ICS/LABAs as SMART showed a greater gain in QALYs at lower total treatment costs.
