Cytomorphological and histomorphological features of lung adenocarcinoma with epidermal growth factor receptor mutation and anaplastic lymphoma kinase gene rearrangement.

Lung cancer is among the lethal and most prevalent oncological diseases globally. It is known that two types of mutations, namely anaplastic lymphoma kinase (ALK) gene rearrangement and epidermal growth factor receptor (EGFR) gene mutation, are responsible for the development of lung adenocarcinoma. The present study aimed to investigate the differences in the frequency of clinical, cytomorphological and histomorphological features of ALK and EGFR-positive lung adenocarcinomas. The present retrospective study comprised 101 patients diagnosed with lung adenocarcinoma. Based on the molecular findings, the patients were categorized into three groups as follows: The ALK-rearranged group (n=28), the EGFR group (n=42) and the negative group (n=31). The clinical features analyzed included sex, age, smoking status and disease stage. The cytomorphological and histomorphological features examined encompassed the following: Cell cluster size, the arrangement of tumor cells, the size of nuclei, nuclear atypia, the visibility of nucleoli, the presence of necrosis, intracytoplasmic vacuoles, signet ring cells, stromal characteristics and the presence of inflammatory infiltrate presence. The results indicated that the female sex was more prevalent in the EGFR group, but statistically significant differences (P<0.05) were observed between the EGFR and negative group. A significantly greater percentage of non-smokers was identified in the EGFR group compared with the ALK group (P<0.01). The majority of patients with confirmed ALK or EGFR mutations received onco-specific treatment. Focal and abundant necrosis was significantly less common in cytological samples in the EGFR group than in the other groups (21.43 vs. 57.14 and 51.61%, combined, P<0.01). No significant differences were observed in other cytomorphological features between the groups. Intracytoplasmic vacuoles, signet ring cells and cells with visible nucleoli were significantly more frequent in histological specimens of the ALK group (P<0.01). The predictive model composed of these features or combined with sex and smoking habits exhibited statistically significant differences for mutation status as a criterion (P<0.01). Collectively, the findings of the present study confirmed that, in addition to clinical characteristics, certain cytological and histological features of lung adenocarcinoma are associated with the mutational status of the tumor.

Prokaryotic Expression of Coat Protein Gene of Grapevine Berry Inner Necrosis Virus and Preparation of Its Polyclonal Antibody

Grapevine berry inner necrosis virus (GINV) and grapevine Pinot gris virus (GPGV) are prevalent viral diseases affecting viticulture, posing significant threats in grape-producing regions of China. Previous studies have emphasized the harmful effects of grape viruses on the grape industry all over the world. However, few reports have focused specifically on GINV. In wild grapevines, GINV infection frequently leads to grapevine fanleaf degeneration disease (GFDD). GINV often co-occurs with other grape viruses, exacerbating its harmful effects on the grapevine industry in China. In this study, we collected grapevine samples from Taizhou city, Jiangsu Province, where GINV infection was confirmed. Based on the GINV coat protein (CP) gene, we developed a high-throughput and high-sensitivity direct antigen-coated ELISA and Dot blot assay for field diagnosis of GINV CP in grape samples. The CP gene was cloned from GINV-infected grape samples, and the GINV CP was expressed using the pET30(a) vector. Specific polyclonal antiserum CPGINV was generated by immunizing rabbits with the purified protein, and its sensitivity was determined to be satisfactory. Leveraging the high accuracy and sensitivity of the CPGINV antiserum, we developed a rapid, precise, and scalable diagnostic method for GINV in the grapevine industry. The established ELISA and Dot blot assays successfully detected GINV-infected grapevine samples. The occurrence of GINV is relatively common in China, which poses a risk of transmission and threatens the healthy development of the grape industry. Therefore, this study prepared CPGINV antiserum and established an efficient, rapid, sensitive, accurate, and high-throughput diagnostic method, providing a foundational approach for the prevention and control of vitis viral diseases.

Guideline for the Prevention and Treatment of Metabolic Dysfunction-associated Fatty Liver Disease (Version 2024).

With the rising epidemic of obesity, metabolic syndrome, and type 2 diabetes mellitus in China, metabolic dysfunction-associated non-alcoholic fatty liver disease has become the most prevalent chronic liver disease. This condition frequently occurs in Chinese patients with alcoholic liver disease and chronic hepatitis B. To address the impending public health crisis of non-alcoholic fatty liver disease and its underlying metabolic issues, the Chinese Society of Hepatology and the Chinese Medical Association convened a panel of clinical experts to revise and update the "Guideline of prevention and treatment of non-alcoholic fatty liver disease (2018, China)". The new edition, titled "Guideline for the prevention and treatment of metabolic dysfunction-associated fatty liver disease (Version 2024)", offers comprehensive recommendations on key clinical issues, including screening and monitoring, diagnosis and evaluation, treatment, and follow-up for metabolic dysfunction-associated fatty liver disease and metabolic dysfunction-associated steatotic liver disease. Metabolic dysfunction-associated fatty liver disease is now the preferred English term and is used interchangeably with metabolic dysfunction-associated steatotic liver disease. Additionally, the guideline emphasizes the importance of multidisciplinary collaboration among hepatologists and other specialists to manage cardiometabolic disorders and liver disease effectively.

Molecular mechanisms of obesity predisposes to atopic dermatitis.

Obesity is a prevalent metabolic disease that reduces bacterial diversity, colonizes the epidermis with lipophilic bacteria, and increases intestinal pro-inflammatory species, all of which lead to impaired epithelial barriers. Adipose tissue secretes immunomodulatory molecules, such as adipokines, leptin, and adiponectin, which alters the morphology of adipocytes and macrophages as well as modulates T cell differentiation and peripheral Th2-dominated immune responses. Atopic dermatitis (AD) and obesity have similar pathological manifestations, including inflammation as well as insulin and leptin resistance. This review examines the major mechanisms between obesity and AD, which focus on the effect on skin and gut microbiota, immune responses mediated by the toll like receptor (TLR) signaling pathway, and changes in cytokine levels (TNF-a, IL-6, IL-4, and IL13). Moreover, we describe the potential effects of adipokines on AD and finally mechanisms by which PPAR-γ suppresses and regulates type 2 immunity.

Assessment of coral diseases in the shallow reefs of Aka-jima Marine Reserve (AMR), with a brief geographic perspective of disease occurrence throughout the larger Kerama-Shoto Marine National Park (KMNP), Okinawa, Japan

This study reports on the observation of coral diseases within the shallow/intertidal water habitat of the Akajima Marine Reserve (AMR), located within the Keramashoto Marine National Park (KMNP) of Japan. Major coral genera and species assessed during the survey included Montipora spp., Porites spp., Isopora palifera, Acropora spp., as well as others. Observed diseases and health conditions included Black Band Disease (BBD) in Montipora as well as in Goniopora, Skeletal Growth Anomalies (GAs) in Acropora, Montipora, Porites, Isopora and Astreopora, Terpios hoshinota covering Acropora, Montipora and Seriatopora, as well as bleaching, discoloration, and other compromised health signs. This field study recorded the presence of GAs in the genus Leptastrea for the first time within the Japanese Archipelago. The novelty in this study is reporting unreported genera to be infested with certain disease conditions, further this study demonstrates how surveys in previously poorly studied areas or habitats can reveal important information pertaining to coral diseases, thus helping to fill existing knowledge gaps. Another important aspect of this study is, we provide a review of the distribution of coral diseases within the KMNP based on our results and previous reports. Being a rapid survey, the dynamics of these diseases were not assessed, while the major cause(s) of the diseases remains to be identified. In general, climate change-related aspects including rises in sea surface temperature, as well as other factors such as host density may be responsible for disease prevalences in the region.

Nepali oral microbiomes reflect a gradient of lifestyles from traditional to industrialized

BackgroundLifestyle plays an important role in shaping the gut microbiome. However, its contributions to the oral microbiome remain less clear, due to the confounding effects of geography and methodology in investigations of populations studied to date. Furthermore, while the oral microbiome seems to differ between foraging and industrialized populations, we lack insight into whether transitions to and away from agrarian lifestyles shape the oral microbiota. Given the growing interest in so-called “vanishing microbiomes” potentially being a risk factor for increased disease prevalence in industrialized populations, it is important that we distinguish lifestyle from geography in the study of microbiomes across populations.ResultsHere, we investigate salivary microbiomes of 63 Nepali individuals representing a spectrum of lifestyles: foraging, subsistence farming (individuals that transitioned from foraging to farming within the last 50 years), agriculturalists (individuals that have transitioned to farming for at least 300 years), and industrialists (expatriates that immigrated to the USA within the last 20 years). We characterize the role of lifestyle in microbial diversity, identify microbes that differ between lifestyles, and pinpoint specific lifestyle factors that may be contributing to differences in the microbiomes across populations. Contrary to prevailing views, when geography is controlled for, oral microbiome alpha diversity does not differ significantly across lifestyles. Microbiome composition, however, follows the gradient of lifestyles from foraging through agrarianism to industrialism, supporting the notion that lifestyle indeed plays a role in the oral microbiome. Relative abundances of several individual taxa, including Streptobacillus and an unclassified Porphyromonadaceae genus, also mirror lifestyle. Finally, we identify specific lifestyle factors associated with microbiome composition across the gradient of lifestyles, including smoking and grain sources.ConclusionOur findings demonstrate that by studying populations within Nepal, we can isolate an important role of lifestyle in determining oral microbiome composition. In doing so, we highlight the potential contributions of several lifestyle factors, underlining the importance of carefully examining the oral microbiome across lifestyles to improve our understanding of global microbiomes.CnT2gR8wWnMkEju1223Bx6Video

MiR-193b-5p and miR-374b-5p Are Aberrantly Expressed in Endometriosis and Suppress Endometrial Cell Migration In Vitro.

(1) Background: Endometriosis is a highly prevalent gynecological disease affecting 10% of women of reproductive age worldwide. miRNAs may play a role in endometriosis, though their exact function remains unclear. This study aimed to identify differentially expressed miRNAs in endometriosis and study their functions in the disease. (2) Methods: Endometrial tissue was collected from women with endometriosis (n = 15) and non-endometriosis controls (n = 17). Dysregulated miRNAs were identified through small RNA-sequencing, and their biological significance was explored by target gene prediction and pathway analysis. Selected miRNAs were examined in paired ectopic endometriomas and eutopic endometrium (n = 10) using qRT-PCR. Their roles in cell migration and proliferation were further examined in vitro using functional assays. To identify potential target genes, we performed mRNA sequencing on transfected cells and the endometrioma cohort. (3) Results: We identified 14 dysregulated miRNAs in the eutopic endometrium of women with endometriosis compared to endometrial tissue from women without endometriosis. Pathway analysis indicated enrichment in cell migration and proliferation-associated pathways. Further ex vivo studies of miR-193b-5p and miR-374b-5p showed that both miRNAs were upregulated in endometrioma. Overexpression of these two miRNAs in vitro inhibited cell migration, and mRNA sequencing revealed several migration-related genes that are targeted by these miRNAs. (4) Conclusions: Our study identified two key endometrial miRNAs that may be involved in the pathogenesis of endometriosis by regulating cell migration.

The Impact of Combined Cranberry Supplementation and Weight Loss Diet on Inflammatory, Antioxidant, and Apoptosis Biomarkers in Patients with Non-Alcoholic Fatty Liver Disease: A Randomized, Double-Blinded, Controlled Clinical Trial

Background: Non-alcoholic fatty liver disease (NAFLD) is a prevalent chronic liver disease. The aim of this study is to evaluate the effect of combined weight loss diet and cranberry supplementation on anthropometric measurements, inflammation and antioxidant biomarkers in patients with NAFLD. Methods: In this randomized, double-blinded, and controlled clinical trial, 41 NAFLD patients were supplemented with either cranberry or placebo tablets for 12 weeks. Both groups followed a diet of 500-1000 calories less than the estimated energy requirements. Serum levels of total antioxidant capacity (TAC), malondialdehyde (MDA), cytokeratin 18 M30 (CK-18 M30), chemokine C-C motif ligand 2 (CCL2) and tumor necrosis factor alpha (TNF-α) were measured at both baseline and the end of the study. Results: Significant improvements in TAC were observed in the cranberry group and between the two groups (P=0.006 and P=0.011, respectively), but the changes in the placebo group were not significant (P=0.325). There were no statistically significant differences in the serum levels of MDA, CK-18 M30, CCL2 and TNF-α between the cranberry and the placebo groups (P&gt;0.05). Conclusions: It seems that daily consumption of cranberry supplement would be beneficial in increasing serum levels of TAC. Further studies are needed to investigate the effects of anti-inflammatory and antioxidant properties of cranberry on NAFLD.

Treatment Patterns and Glycaemic Control Between 2015 and 2019 in Tianjin, China: A Real-World Study of Adults with Type 2 Diabetes.

Diabetes is associated with a high economic burden in China; therefore, strategies to prevent diabetes, improve glycaemic control, delay disease-related complications and maintain quality of life are essential. This study was conducted to evaluate trends in treatment patterns and glycaemic control in people with type 2 diabetes (T2D) in real-world clinical practice in Tianjin, China. This retrospective, cross-sectional, multicentre study analysed data from adults with T2D living in Tianjin, China between 2015 and 2019, based on information obtained from a regional electronic medical record database. Temporal trends in treatment patterns and glycaemic control were assessed using linear regression (continuous variables), and Cochran-Armitage (two categories) or Cochran-Mantel-Haenszel (≥ 3 categories) tests. Between 2015 and 2019, data from 312,203 individuals treated at 75 hospitals were included. Over this period, there was an upward trend in the prevalence of hypertension, hyperlipidaemia, obesity, cardiovascular disease, stroke and retinopathy each year (all P < 0.001). The use of metformin or dipeptidyl peptidase-4 inhibitors increased, while thiazolidinedione, alpha-glucosidase inhibitor and glinide use decreased; the use of basal insulin (BI), glucagon-like peptide-1 receptor agonists (GLP-1 RAs), GLP-1 RAs + BI, bolus insulin and BI + bolus insulin increased, whereas the use of premixed insulin showed a downward trend (all P < 0.001). From 2015 to 2019, an increased proportion of individuals achieved glycated haemoglobin (HbA1c) < 7% (< 53 mmol/mol; 28.1-33.7%), fasting plasma glucose (FPG) < 7 mmol/l (21.7-26.9%) and postprandial glucose (PPG) < 10 mmol/l (22.0-48.2%; all P < 0.001). There was no change in the proportion of individuals with an FPG ≥ 7 mmol/l and a PPG ≥ 10 mmol/l, while the prevalence of residual hyperglycaemia increased (P < 0.001). Glycaemic control improved between 2015 and 2019 in people with T2D in Tianjin, China; however, there is an unmet need for more effective glycaemic control.

Harnessing farmer engagement to develop a 10-point plan to control Johne's disease in dairy herds

Since the launch of the voluntary National Johne's Management Plan (NJMP) in 2015, the within-herd prevalence of Johne's disease (JD) in the UK has decreased from 8.49% to 2.68%, this reduction occurred by 2022. As part of the NJMP, veterinarians and farmers are required to conduct a risk assessment, examine the herd JD status and formulate a management plan within which farmers commit to one of six management strategies. In response to the success of the NJMP, completion of the NJMP or equivalent scheme has been mandatory under the Red Tractor assurance scheme since 2019. However, levels of engagement with the NJMP among both veterinarians and farmers, and progress with respect to JD prevalence, vary considerably. This paper uses a mixture of literature and expert opinions to discuss these issues and generate the JD Control 10-Point Plan. Failing to control JD is generally not associated with technical issues or inadequate supporting science, but with attitudes, beliefs and communications. The JD Control 10-Point Plan is a practical step-by-step guide for veterinary practices detailing how to develop JD control plans. In summary, veterinary practices should agree on a database which can be used to store data, develop a ‘Johne's disease champion’, conduct knowledge exchange events and follow up with individual farmers to better understand the attitudes and beliefs of their clients. Then, in line with the NJMP, use risk assessment and initial surveillance data to discuss and develop a JD control plan which is to be reviewed annually.

Prevalence of chondrocalcinosis and calcium pyrophosphate deposition disease in a cohort of adult patients with low alkaline phosphatase levels and a positive versus negative genetic ALPL study.

To estimate the prevalence of chondrocalcinosis and calcium pyrophosphate dihydrate deposition disease (CPPD) in patients with low alkaline phosphatase (ALP) levels and a positive ALPL genetic study (+GT) for hypophosphatasia (HPP) compared to those with the same biochemical abnormality and a negative genetic test (-GT). As a secondary objective, to analyze the biochemical factors associated with its presence in subjects with ALPL variants. Seventy-eight subjects with persistently low ALP levels and ALPL genetic test were included. Baseline and 24-mo knee ultrasounds were performed in 42 + GT and 36 -GT subjects, in whom the fibrocartilage, hyaline cartilage of menisci, tendons, and synovial fluid were scanned to detect calcium pyrophosphate deposits. A MyLabTwice ultrasound machine (Esaote) with a multifrequency linear array transducer (4-13MHz) was used. A higher percentage of chondrocalcinosis was observed in the +GT group [9/42 (21.4%)] compared to the -GT group [2/36 (5.6%), p=.045)]. Two patients (4.76%), both in the +GT group, had arthritis secondary to CPPD. No new cases were identified at the 24-mo control. When comparing +GT patients with and without chondrocalcinosis, ALP levels were lower, and pyridoxal-5'-phosphate (PLP) and phosphate levels were higher in the former group (p<.05). Logistic regression analysis revealed that higher PLP levels are associated with the presence of chondrocalcinosis (OR: 1.1; 95% confidence interval, CI, 1.001-1.012). Chondrocalcinosis was a frequent ultrasonographic finding in HPP. Arthritis secondary to calcium pyrophosphate deposits, however, proved less prevalent. Genetic causes, such as HPP, should be considered when evaluating patients with chondrocalcinosis in clinical practice.

Triglyceride-glucose Index and Its combination with obesity indicators mediating the association between 2-hydroxyfluorene and the prevalence of cardiovascular disease: Evidence from the NHANES (2005–2018)

BackgroundPolycyclic aromatic hydrocarbons (PAHs) were increasingly recognized as a group of environmental pollutants associated with various health issues. The rise in their prevalence in the environment was concerning. Yet, the effects of PAH exposure on cardiovascular diseases (CVDs) were still not well understood. PurposeThis study investigated the impact of exposure to 2-hydroxyfluorene on CVDs prevalence, with a special focus on the mediating role of triglyceride-glucose (TyG) index and its combination with obesity indicators. MethodUsing National Health and Nutrition Examination Survey (NHANES) data from 2005 to 2018, this study assessed how 2-hydroxyfluorene affects CVDs prevalence through various statistical techniques. The investigation began with restricted cubic spline (RCS) analysis to explore the relationship between 2-hydroxyfluorene levels and CVDs prevalence. Logistic regression was then used to examine associations within PAH mixtures, alongside the Bayesian Kernel Machine Regression (BKMR) model. Furthermore, the Quantile G-Computation (QG-comp) model was used to evaluate the influence of weights and directions. A mediation analysis was also performed to assess the mediating role of TyG-related indicators on the relationship between 2-hydroxyfluorene and CVDs prevalence. Besides, the association between 2-hydroxyfluorene and the prevalence of each specific CVDs, congestive heart failure, myocardium infarction, angina pectoris and coronary heart disease, was also assessed and so was the mediated effect. Finally, the subgroup analysis was conducted to assess the association in each specific subgroup. ResultThe study, involving 3645 participants, found a significant positive association between 2-hydroxyfluorene exposure and CVD (OR (95 %CI) = 115.8013 (5.0521 ∼ 2654.3248), P=0.0029), with 2-hydroxyfluorene showing the positive contribution to CVDs prevalence within the phthalate mixture. The positive association also existed between 2-hydroxyfluorene and the prevalence of each specific CVDs. TyG and TyGWC (Triglyceride Glucose-Waist Circumference) were identified as mediators in the link between 2-hydroxyfluorene exposure and the prevalence of total CVD and each specific CVD, while TyGBMI (Triglyceride Glucose-Body Mass Index) can only mediate the association between 2-hydroxyfluorene and the prevalence of total CVD, congestive heart failure and angina pectoris ConclusionThe findings highlighted a significant association between 2-hydroxyfluorene exposure and CVDs prevalence, with TyG-related indicators acting as mediators.

The research of influence factors that possibly lead to cardiovascular disease

Abstract. The emergence of cardiac disease is influenced by numerous variables. Every year a large percentage of people around the world die from heart attacks. This study was to look at how important clinical variables are connected to the chance of having CVD. The analysis used a Kaggle dataset with details from 70,000 patients and 10 different variables. The study examined how factors such as age, gender and changes in cardiac activity during exercise affect overall heart health. Multiple linear regression models were used to analyze these effects. The results show a significant correlation between these factors and an increased risk of heart disease. This emphasizes the importance of these predictors in clinical assessments. It can be concluded from this study that regular medical check-ups, early prevention and treatment should be carried out for these vulnerable groups. The general prevalence of heart disease in the nation can be decreased by implementing these strategies. According to the study, personalized health strategies have the potential to improve CVD outcomes and strengthen preventive measures. All of the experimental results suggest that continued documentation and study of these pathogenic factors in medical diagnostics and experiments could aid in drug development as well as improve medical technology and help more patients with cardiovascular disease recover.

Associated risk and resilience factors of Alzheimer's disease in women with early bilateral oophorectomy: Data from the UK Biobank.

Bilateral oophorectomy (BO) confers immediate estradiol loss. We examined prevalence and predictors of Alzheimer's disease (AD) in women with early BO comparing their odds ratios of AD to those of women with spontaneous menopause (SM). A cohort from UK Biobank (n = 34,603) included women aged 60 + at baseline with and without AD who had early BO or SM. AD was determined based on AD related ICD-10 or ICD-9 code. We used logistic regression to model the association of menopause type with AD. Model predictors included age, education, age at menopause, hormone therapy (HT), APOE4, body mass index (BMI), cancer history, and smoking history. Those with early BO had four times the odds of developing AD (OR = 4.12, 95% CI [2.02, 8.44]) compared to those with SM. APOE4 (OR = 4.29, 95% CI [2.43, 7.56]), and older age (OR = 1.16, 95% CI [1.05, 1.28]) were associated with increased odds of AD in the BO group. Greater years of education were associated with reduced odds of AD for both BO (OR = 0.91, 95% CI [0.85, 0.98]), and SM (OR = 0.95, 95% CI [0.90, 0.99]), while ever use of HT was associated with decreased odds of AD only for the BO group (OR = 0.43, 95% CI [0.23, 0.82]). Women with early BO, particularly with an APOE4 allele, are at high risk of AD. Women with early BO who use HT and those with increased education have lower odds of developing AD.

Prevalence of dental caries, oral health status, malocclusion status, and dental treatment needs in thalassemic children: A cross-sectional study

ABSTRACT Background: Thalassemia is a hemoglobinopathy-associated genetic disease resulting due to defective synthesis of globin chains, causing defects in the skeletal and oral structures. Aim: This cross-sectional study was designed to analyze the prevalence of dental caries, oral health status, malocclusion status, and dental treatment needs in thalassemic children. Materials and Methods: Institutional Ethical committee clearance was obtained before starting the study. The study sample comprised 100 thalassemic and 100 normal children in which oral disease markers like dmft/DMFT index, plaque index, gingival index, and Angle’s classification for malocclusion were used. The statistical tool used was ‘one-way ANOVA’ with the probability set at 0.05. Results and Observations: Statistically significant differences in prevalence of dental caries, periodontal disease, malocclusion, and treatment needs were noted in thalassemic individuals when compared to normal subjects. Conclusion: The present study has given an insight into the various oral and dentomaxillofacial manifestations of thalassemia, thus considering the importance of routine oral examination for the prevention of dental caries and periodontal diseases.

Identification of Mood Disorders in Self-Reported Versus Health Administrative Data.

Producing relevant knowledge on the prevalence of mood disorders (MDs) requires a clear identification of people living with the condition. Analyzing this multifaceted disease from the perspective of health administrative data and population-based surveys could contribute to document inconsistencies between these data sources and highlight the strengths and limitations of each methodological approaches. The aim of this study was to estimate the prevalence of MD disease, assess concordance of MD patterns in population-based surveys versus health administrative data, and investigate statistical differences in characteristics between individuals presenting the disease in each data sources. This study used the Care Trajectories-Enriched Data (TorSaDE) cohort. The TorSaDE cohort is built by merging five waves of the Canadian Community Health Survey (CCHS) with health administrative data of the province of Quebec, Canada. The sample includes individuals who participated in at least one round of CCHS and for whom evidence of use of health services in the year of CCHS completion and the year before were present in health administrative data. The cohort was split into four groups based on the presence and absence of MD in self-reported versus health administrative data. Groups' characteristics were compared using chi-square tests and ANOVA. The study cohort was composed of 96,079 individuals, of which 10,418 (10.8%) had MD, regardless of the data sources. Self-reported prevalence of MD was 6.03%, while the prevalence from health administrative data was about 7.79%. Estimates showed a low level of concordance between the two measures, as only 27.4% of people presenting this medical condition were identified in both data sources. Furthermore, individuals identified with MD only in survey data had poorer socioeconomic outcomes but better health outcomes than those from the concordant group (i.e., identified in both data sources). In addition, people presenting MD in health administrative data only had better socioeconomic and health outcomes than those who reported MD diagnosis only in survey data. Findings suggest that each measure capture different specific subpopulations. Estimates obtained from each source should thus be contextualized and interpreted with caution.

Prevalence of Pediatric Inflammatory Bowel Disease in the United States: Pooled Estimates from Three Administrative Claims Data Sources.

Prevalence of Trypanosoma cruzi Infection in Pregnant Women and Risk of Vertical Transmission in Newborns in Chiapas, Mexico.

The Mexican state of Chiapas is considered epidemiologically significant for Chagas disease due to the coexistence of infected reservoirs and vectors, including migratory populations from Central and South America. However, there is a lack of monitoring programs for the timely detection of this disease. The objective of this study was to elucidate the prevalence of Trypanosoma cruzi infection in pregnant women and the risk of vertical transmission in newborns at two hospitals located in the Metropolitan Region of Tuxtla Gutierrez, the capital of Chiapas State Mexico. A cross-sectional study was carried out with 193 pregnant women with gestational ages between 32 and 40 weeks, who underwent immunological testing to diagnose Chagas disease. Conventional PCR testing on cord blood revealed the presence of T. cruzi in newborns. The prevalence of T. cruzi infection in pregnant women was 32.12% (95% confidence interval (CI): 0.25, 0.38). The 62 pregnant women who tested positive for Chagas disease gave birth to 63 children, and in 5 newborns (8% (5/62), 95% confidence interval (CI): 0.02, 0.19), PCR tests on umbilical cord blood were positive for T. cruzi. In conclusion, the dataset showed a high prevalence of Chagas disease in the sample of pregnant women studied and a maternal-fetal transmission rate of 8%.

Yield of Coronary Assessment in Sustained Monomorphic Ventricular Tachycardia

Coronary assessment is frequently conducted in patients with sustained monomorphic ventricular tachycardia (SMVT); however, its yield and subsequent treatment implications remain unclear. This study aimed to determine the prevalence of coronary artery disease (CAD) in patients presenting with SMVT, factors influencing clinician referral for coronary assessment, and clinical outcomes based on revascularisation or medical management of CAD. Consecutive patients presenting with acute SMVT requiring inpatient admission between 2017 and 2022 were identified. A total of 249 individual patients with SMVT were identified, with 140 undergoing coronary assessment. Referral for coronary assessment was driven by chest pain (p<0.001) and increased troponin kinetics (p<0.001). No patient with SMVT had an acute coronary occlusion. Significant CAD was found in 48 (34%) patients, and traditional ischaemic features did not predict significant CAD. Nineteen (40%) patients with significant CAD underwent revascularisation (n=15 percutaneous coronary intervention, n=4 coronary artery bypass grafting). There was no significant difference in time to ventricular tachycardia (VT) recurrence between revascularised and medically managed CAD (hazard ratio 1.670; 95% confidence interval 0.756-3.687; p=0.199). A total of five of six patients who underwent a revascularisation-only strategy (no upfront antiarrhythmic therapy or ablation) had VT recurrence (median time to recurrence 8.9 months). Despite being frequently performed, coronary assessment in SMVT has only modest yield, with no patients having an acute coronary occlusion. Traditional clinical factors of ischaemia did not improve this yield. Revascularisation alone did not improve freedom from VT.

Routine radiographs of hands and feet do not have diagnostic or prognostic value in patients with clinically suspect arthralgia: a large longitudinal study

BackgroundConventional radiographs of hands and feet are used to depict structural damage in rheumatoid arthritis (RA). This is also commonly done in clinical practice in symptomatic patients at risk for...
