Early recognition of BRASH syndrome is crucial, as the synergistic interplay of AV nodal blockade, renal failure, and hyperkalemia can rapidly lead to circulatory collapse. Prompt identification and withdrawal of offending agents enable complete recovery from this reversible condition.

Young adults presenting with acute psychiatric symptoms followed by rapid neurological decline, catatonia, and autonomic instability should prompt consideration of anti–NMDA receptor encephalitis, even without detectable tumors; early recognition and immunotherapy are critical for favorable neurological recovery.

Background Previous meta‐analyses have shown mixed results regarding the association between eating disorders (EDs) and type 1 diabetes mellitus (T1DM). Our paper aimed to analyse different EDs and disordered eating behaviours that may be practiced by patients with T1DM. Methods A literature search of PubMed, Scopus and Web of Science was conducted on 17 January 2023, using the key terms “T1DM,” “Eating Disorders” and “Bulimia.” Only observational controlled studies were included. The Revman software (version 5.4) was used for the analysis. Results T1DM was associated with increased risk of ED compared with nondiabetic individuals (RR = 2.47, 95% CI = 1.84–3.32, p‐value < 0.00001), especially bulimia nervosa (RR = 2.80, 95% CI = 1.18–6.65, p‐value = 0.02) and binge eating (RR = 1.53, 95% CI = 1.18–1.98, p‐value = 0.001). Our analysis has shown that increased risk of ED among T1DM persisted regardless of the questionnaire used to diagnose ED; DM‐validated questionnaires (RR = 2.80, 95% CI = 1.91–4.12, p‐value < 0.00001) and generic questionnaires (RR = 2.03, 95% CI = 1.27–3.23, p‐value = 0.003). Prevalence of insulin omission/misuse was 10.3%; diabetic females demonstrated a significantly higher risk of insulin omission and insulin misuse than diabetic males. Conclusion Our study establishes a significant and clear connection between EDs and T1DM, particularly bulimia and binge eating, with T1DM. Moreover, female diabetics are at higher risk of insulin misuse/omission. Early proactive screening is essential and tailored; comprehensive interventions combining diabetes and ED components are recommended for this population, with referral to a specialised psychiatrist. Patients with T1DM had a higher risk of eating disorders than the control group. Specifically, bulimia nervosa and binge eating exhibited statistically significant associations with T1DM, while anorexia nervosa did not. The risk of disordered eating behaviours did not differ significantly between patients with T1DM and the control group. However, diabetic patients did exhibit a significantly elevated risk of insulin omission/misuse.

Background Studies have shown mixed results regarding the association between irritable bowel syndrome (IBS) and metabolic syndrome (MS); This study aimed to assess the susceptibility of IBS patients to MS and its individual components. Methods PubMed, Scopus, Embase, and Web of Science were searched on 1/1/2023. Eligible studies were screened, and data on study characteristics, IBS diagnostic criteria, and metabolic syndrome components were extracted. Data were analysed in RevMan 5.4, with results reported as relative risk (RR) or mean difference (MD) and 95% confidence intervals. Statistical significance was set at p < 0.05. Results IBS was associated with an increased risk of MS (RR = 2.05, 95% CI = 1.50–2.79, p < 0.00001), with a higher risk among IBS‐D patients (RR = 3.09, 95% CI = 2.41–3.97, p < 0.00001). IBS patients showed increased HOMA‐IR (MD = 0.21, 95% CI = 0.15–0.26, p < 0.00001), higher obesity risk (RR = 1.46, 95% CI = 1.10–1.93, p = 0.009), elevated BMI (MD = 1.51, 95% CI = 0.98–2.03, p‐value < 0.00001), waist circumference (MD = 5.01, 95% CI = 1.29–8.72, p = 0.008), and an association with systolic hypertension (MD = −0.50, 95% CI = −0.60 to −0.40, p‐value < 0.00001). IBS was also linked to higher LDL (MD = 5.98, 95% CI = 0.91–11.05, p = 0.02), total cholesterol (MD = 12.21, 95% CI = 6.23–18.18, p < 0.0001), and triglycerides (MD = 11.93, 95% CI = 11.55–12.31, p < 0.00001). Conclusions This analysis indicates a potential association between IBS and metabolic syndrome, including its components such as obesity, hypertension, and lipid profile abnormalities. However, significant heterogeneity among studies limits the generalisability of these findings. Clinicians should remain aware of the possible link and consider individualised preventive and management strategies.

Emerging and re-emerging plant diseases continue to present multifarious threats to global food security. Considerable recent efforts are therefore being channeled towards understanding the nature of pathogen emergence, their spread and evolution. Xanthomonas euvesicatoria pv. perforans (Xep), one of the causal agents of bacterial spot of tomato, rapidly emerged and displaced other bacterial spot xanthomonads in many tomato production regions around the world. In less than three decades, it has become a dominant xanthomonad pathogen in tomato production systems across the world and presents a compelling example for understanding diversi'cation of recently emerged bacterial plant pathogens. Although Xep has been continuously monitored in Florida since its discovery, the global population structure and evolution at the genome-scale is yet to be fully explored. The objectives of this work were to determine genetic diversity globally to ascertain if different tomato production regions contain genetically distinct Xep populations, to examine genetic relatedness of strains collected in tomato seed production areas in East Asia and other production regions, and to evaluate variation in type III secretion effectors, which are critical pathogenicity and virulence factors, in relationship to population structure. We used genome data from 270 strains from 13 countries for phylogenetic analysis and characterization of type III effector gene diversity among strains. Our results showed notable genetic diversity in the pathogen. We found genetically similar strains in distant tomato production regions, including seed production regions, and diversi'cation over the past 100 years, which is consistent with intercontinental dissemination of the pathogen in hybrid tomato production chains. Evolution of the Xep pangenome, including the acquisition and loss of type III secreted effectors, is apparent within and among phylogenetic lineages. The apparent long-distance movement of the pathogen, together with variants that may not yet be widely distributed, poses risks of emergence of new variants in tomato production.

Background Bacterial spot of pepper (BSP), caused by four different Xanthomonas species, primarily X. euvesicatoria (Xe) , poses a significant challenge in pepper cultivation. Host resistance is considered the most important approach for BSP control, offering long-term protection and sustainability. While breeding for resistance to BSP for many years focused on dominant R genes, introgression of recessive resistance has been a more recent focus of breeding programs. The molecular interactions underlying recessive resistance remain poorly understood. Results In this study, transcriptomic analyses were performed to elucidate defense responses triggered by Xe race P6 infection by two distinct pepper lines: the Xe -resistant line ECW50R containing bs5 , a recessive resistance gene that confers resistance to all pepper Xe races, and the Xe -susceptible line ECW. The results revealed a total of 3357 upregulated and 4091 downregulated genes at 0, 1, 2, and 4 days post-inoculation (dpi), with the highest number of differentially expressed genes (DEGs) observed at 2 dpi. Pathway analysis highlighted DEGs in key pathways such as plant-pathogen interaction, MAPK signaling pathway, plant hormone signal transduction, and photosynthesis – antenna proteins, along with cysteine and methionine metabolism. Notably, upregulation of genes associated with PAMP-Triggered Immunity (PTI) was observed, including components like FLS2, Ca-dependent pathways, Rboh, and reactive oxygen species (ROS) generation. In support of these results, infiltration of ECW50R leaves with bacterial suspension of Xe led to observable hydrogen peroxide accumulation without a rapid increase in electrolyte leakage, suggestive of the absence of Effector-Triggered Immunity (ETI). Furthermore, the study confirmed that bs5 does not disrupt the effector delivery system, as evidenced by incompatible interactions between avirulence genes and their corresponding dominant resistant genes in the bs5 background. Conclusion Overall, these findings provide insights into the molecular mechanisms underlying bs5 -mediated resistance in pepper against Xe and suggest a robust defense mechanism in ECW50R, primarily mediated through PTI. Given that bs5 provides early strong response for resistance, combining this resistance with other dominant resistance genes will enhance the durability of resistance to BSP.

BackgroundWide-area transepithelial sampling (WATS) is a new technique that uses an abrasive brush to obtain samples from a larger surface area of the oesophagus. Studies have shown promising results that WATS in adjunct to forceps biopsy (FB) increases the detection rate of Barrett’s oesophagus (BE) as well as oesophageal dysplasia (ED). We conducted a systematic review and meta-analysis to compare the detection rates of BE and ED between FB and WATS in adjunct to FB.MethodsA Literature search was done using electronic databases, including PubMed, Embase, Scopus, Cochrane and CINAHL from inception to 26 April 2020. A meta-analysis comparing detection rates of WATS in adjunct to FB versus FB using the random-effects model was done using RevMan V.5.3.ResultsPooled data from 20 392 endoscopies across 11 studies showed an absolute increase in detection of 16% (95% CI 0.10% to 0.22%, p<0.00001). A relative increase of 1.62 was seen in detection rates of BE (95% CI 1.28 to 2.05, p<0.0001) when WATS was used with FB with the number needed to test (NNT) of 6.1 patients. For ED, a 2% absolute increase (95% CI 0.01 to 0.03, p=0.001) in additional diagnostic yield from WATS. A relative increase of 2.05 was seen in the detection rate of ED (95% CI 1.42 to 2.98, p=0.0001) yielding an NNT of 50 patients.ConclusionOur study shows that WATS, as an adjunct to FB, improves both the absolute detection rate and relative detection rate of both BE and ED as compared to FB alone.
