Introduction: Atrial high-rate episodes (AHRE) have been linked to increased thromboembolic risk and all-cause mortality in patients with cardiac implantable electronic devices (CIEDs). Various predictors of AHRE development have been identified, emphasizing the need for close monitoring and the potential transition to clinical atrial fibrillation (AF). However, the predictive value of P wave characteristics on AHRE development remains conflicting. This meta-analysis aims to summarize existing data to investigate this association., Method: We examined studies from MEDLINE and EMBASE databases up to May 2024 to investigate the association of baseline P-wave duration (PWD), P-wave dispersion (PWDIS), and interatrial block (IAB) with the risk of developing AHRE. We extracted the mean and standard deviations of PWD and PWDIS to calculate the pooled mean difference (MD). Risk ratios (RR) and 95% confidence intervals (CIs) were used to assess the association between IAB and AHRE risk, using the generic inverse variance method for combination., Results: The meta-analysis included nine studies. Patients with AHRE had longer PWD and PWDIS compared to those without AHRE, with a pooled MD for PWD of 9.17 ms (95% CI: 4.74-13.60; I 2 = 47%, p < 0.001) and a pooled MD for PWDIS of 20.56 ms (95% CI: 11.57-29.56; I 2 = 57%, p < 0.001). Additionally, patients with IAB had a higher risk of developing AHRE, with a pooled RR of 3.33 (95% CI: 2.53-4.38; I 2 = 0%, p < 0.001), compared to those without IAB., Conclusions: Our meta-analysis found that patients with AHRE had higher PWD and PWDIS than those without AHRE. Additionally, IAB was associated with a higher risk of developing AHRE. These findings emphasize the importance of close monitoring and risk stratification, particularly for patients with P wave abnormalities., (© 2024 Wiley Periodicals LLC.)

Introduction: Colon cancer is the second most common cause of death in the United States. With an increasing number of patients diagnosed at younger ages, the disease remains a significant burden. However, recent data on early onset patients admitted with colon cancer are still limited., Methods: We utilized the 2016 to 2021 National Inpatient Sample to investigate trends and characteristics of colon cancer hospitalizations. Nonelective participants were divided into early onset and normal-age groups, with a cut point of 50 years old. In addition, we also investigated factors associated with the risk of inpatient mortality in the study population., Results: There were 26,903 early onset nonelective colon cancer hospitalizations in the population group, amounting to 11.91% of total colon cancer hospitalizations. No significant changes or trends were seen from 2016 to 2021. Compared to the normal-age population group, there was a disproportionate number of Blacks, Hispanics, and Asian Americans, as well as those with obesity and tobacco usage., Conclusion: Some demographic factors and comorbidities disproportionately affect early onset colon cancer patients when compared to the normal-age population group. Further investigations are necessary to combat the growing incidence of early onset colon cancer., Competing Interests: The authors report no funding or conflicts of interest., (Copyright © 2024 Baylor University Medical Center.)

Objective: Metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiometabolic conditions affect populations across economic strata. Nevertheless, there are limited epidemiological studies addressing these diseases in low (LICs) and lower-middle-income countries (lower MICs). Therefore, an analysis of the trend of MASLD and cardiometabolic conditions in these countries is necessary., Methods: From 2000 to 2019, jointpoint regression analysis was employed to calculate the prevalence, mortality, and disability-adjusted life years (DALYs) for cardiometabolic conditions including MASLD, type 2 diabetes mellitus (T2DM), dyslipidemia (DLP), hypertension (HTN), obesity, peripheral artery disease (PAD), atrial fibrillation and flutter (AF/AFL), ischemic heart disease (IHD), stroke, and chronic kidney disease from HTN and T2DM, in LICs and lower MICs (according to the World Bank Classification 2019) using the Global Burden of Disease 2019 data., Results: Among the eleven cardiometabolic conditions, MASLD (533.65 million), T2DM (162.96 million), and IHD (76.81 million) had the highest prevalence in LICs and Lower MICs in 2019. MASLD represented the largest proportion of global prevalence in these countries (43 %). From 2000 to 2019, mortality in LICs and lower MICs increased in all cardiometabolic conditions, with obesity-related mortality having the highest increase (+134 %). During this timeframe, there were increased age-standardized death rates (ASDR) from obesity, PAD, and AF/AFL. From all conditions, the DALYs-to-prevalence ratio was higher in LICs and lower MICs than the global average., Conclusion: The burden of MASLD and cardiometabolic conditions is increasing worldwide, with LICs and lower MICs experiencing higher (DALYs) disability per prevalence. As these conditions are preventable, counteracting these trends requires not only the modification of ongoing actions but also the strategizing of immediate interventions., Competing Interests: Declaration of competing interest Mazen Noureddin has been on the advisory board for 89BIO, Gilead, Intercept, Pfizer, Novo Nordisk, Blade, EchoSens, Fractyl, Terns, Siemens, and Roche diagnostic; has received research support from Allergan, BMS, Gilead, Galmed, Galectin, Genfit, Conatus, Enanta, Madrigal, Novartis, Pfizer, Shire, Viking and Zydus; and is a minor shareholder or has stocks in Anaetos, Rivus Pharma and Viking.

Despite advances in ablative therapies, outcomes remain less favorable for persistent atrial fibrillation often due to presence of non-pulmonary vein triggers and abnormal atrial substrates. This review highlights advances in ablation technologies and notable scientific literature on clinical outcomes associated with pursuing adjunctive ablation targets and substrate modification during persistent atrial fibrillation ablation, while also highlighting notable future directions.

Malignant small bowel obstruction (mSBO) is a frequent complication in patients with gastrointestinal or gynecologic cancers. For those with inoperable cancers and persistent obstructive symptoms, symptom palliation with a percutaneous gastrostomy tube (PGT) may be required. However, excessive fluid loss from the PGT can lead to significant fluid, electrolyte, and acid-base imbalances. We present a case of a man with metastatic colonic adenocarcinoma who developed mSBO, acute kidney injury, and metabolic alkalosis, all of which were effectively managed with octreotide., Competing Interests: Human subjects: Consent was obtained or waived by all participants in this study.

Background/aims: Various socioeconomic and racial disparities are well-documented for colon cancer. However, the association of dementia, which is a growing cause of mortality in the elderly, remains unexplored. We aim to understand the association between these two conditions, in the elderly population group., Methods: We utilized the 2020 National Inpatient Sample to investigate records admitted for colorectal cancer identified through ICD-10 CM codes. We divided records by the presence of dementia. Adjusted odds ratios (aORs) for predefined outcomes were determined using multivariable logistic and linear regression models, adjusting for comorbidities. The primary outcome assessed was inpatient mortality, while secondary outcomes include other inpatient complications., Results: We identified 33,335 hospitalizations with ages more than 60. The mean age was 75.2 and males constituted 50.4%. In a survey multivariable logistic and linear regression model adjusting for patient and hospital factors, utilizing propensity score matching, the presence of dementia is associated with lower inpatient mortality (aOR 0.49, 95% confidence interval [CI] [0.26, 0.92], p=0.03), lower hospitalization costs (beta coefficient -2,823, 95% CI [-5,266, -440], p=0.02), lower odds of acute respiratory failure (aOR 0.54, p=0.01), lower mechanical ventilation usage (aOR 0.26, p<0.01) but higher odds of mental status change (aOR 1.97, 95% CI [1.37, 2.84], p<0.01)., Conclusions: The presence of dementia is associated with a lower risk of inpatient mortality, and other clinical outcomes, in colorectal cancer cases admitted for hospitalization. Etiologies behind this relationship should be explored to understand this inverse relationship.

Introduction: Constipation is one of the most common gastrointestinal complaints in the United States, and multiple interventions and behavioral changes are often required to alleviate it. Vegetables are often one of the diet recommendations for constipated patients, but the amount required for constipation impact is still limited., Methods: We conducted a nationwide cross-sectional study with the 2006 to 2010 National Health and Nutrition Examination Survey (NHANES) database. Patients >20 years old were stratified into four quartiles of vegetable intake. We used multivariable logistic regression to determine the association between vegetable intake and constipation status as recorded in the database., Results: A total of 13,832 patients were included in the study. The average age was 50.5 years; 49.6% of the population was Caucasian, and 26.43% were Hispanic. In the population, 9.93% had constipation, and 92.65% had vegetable consumption. After adjusting for multiple factors, patients with larger vegetable consumption had lower odds of constipation (adjusted odds ratio 0.60; 95% confidence interval 0.49, 0.73; P  < 0.001) when compared to the first quartile. Postpropensity score matching revealed similar statistical significance., Conclusion: A larger amount of vegetable intake is associated with lower odds of constipation. Additional investigations on vegetable subtype, as well as the longitudinal relationship, are required to understand this relationship., Competing Interests: The authors report no funding or conflicts of interest., (Copyright © 2024 Baylor University Medical Center.)

Recent advances in immunotherapy using immune checkpoint inhibitors (ICIs) for various cancers have also highlighted a rise in immune-related adverse events, including hepatitis, potentially leading to the discontinuation of treatment. This study aimed to evaluate the prevalence of hepatitis in metastatic colorectal cancer (mCRC) patients undergoing different ICI therapies. An extensive search of PubMed, PubMed Central, and Google Scholar up to November 2023 identified relevant studies. After excluding non-English articles, case reports, reviews, ongoing trials, and studies combining other therapies, five studies qualified for inclusion. Data extraction and statistical analyses were performed using Excel and Comprehensive Meta-Analysis software, respectively. Results from a subgroup analysis indicated that the incidence of hepatitis was comparable among patients treated with PD-1 monotherapy, PDL-1 monotherapy, and combination PD-1 and CTLA-4 therapy, with rates of 2.6%, 2.2%, and 1.7% for any grade and 2.1%, 2.2%, and 1.7% for grade ≥3 hepatitis, respectively. Naive-treated mCRC patients exhibited higher hepatitis rates than those previously treated (3.2% vs 1.6% and 2.6% vs 1.6% for any grade and grade ≥3, respectively). This study underscores the similar risk of hepatitis across different ICI therapies, with an increased incidence in naive-treated mCRC patients., Competing Interests: The authors report no funding or conflicts of interests, (Copyright © 2024 Baylor University Medical Center.)

Background and Objective: Early-onset pancreatic cancer (EOPC) is associated with poor prognosis and high disease burden. Metabolic risk factors such as diabetes and obesity are considered risk factors of EOPC. Recently, there has been an increasing number of EOPCs worldwide. However, the analysis of EOPC, including its metabolic risk factors, in the Middle East and North Africa (MENA) region has not been fully addressed., Methods: Data from the Global Burden of Disease Study between 2000 and 2019 was used to analyze the prevalence, incidence, deaths and disability-adjusted life years (DALYs) associated with EOPC and its metabolic risk factors. The analysis further categorized the data based on countries, income status and sex and examined the annual percentage change (APC)., Results: Approximately 2800 cases, 2400 deaths and 114,000 DALYs were attributable to EOPC in the MENA region. The incidence (APC + 3.42%), death (APC + 0.73%) and DALYs (APC + 3.23%) rates of EOPC increased. In addition, the death and DALY rates of EOPC attributable to obesity and diabetes increased. High and upper-middle-income countries exhibited a higher burden of EOPC than lower-income countries., Conclusion: Over the past two decades, the burden of EOPC and its associated metabolic risk factors has increased. There is an urgent need for region-wide policy development, including screening methods and risk factor reduction, to mitigate the high and rising burden of EOPC in the MENA region., (© 2024.

Background: In heart failure with reduced ejection fraction (HFrEF), sodium-glucose cotransporter-2 (SGLT2) inhibitors were demonstrated to lower cardiovascular mortality (CV death) and hospitalization for heart failure (HHF); however, the advantages of SGLT2 inhibitors in heart failure with mildly reduced (HFmrEF) or preserved ejection fraction (HFpEF) are less clear. SGLT2 inhibitors were reported to enhance quality of life (QoL) in HFmrEF or HFpEF patients; however, the findings among studies are inconsistent., Objective: To conduct an updated systematic review and meta-analysis of recent data to assess the effect of SGLT2 inhibitors on cardiovascular outcomes and QoL in patients with HFmrEF or HFpEF., Method: Three databases were searched for studies that evaluated SGLT2 inhibitors and their effect on cardiovascular outcomes, including CV death, HHF, all-cause death, and the composite outcome of CV death, HHF, and urgent visit for heart failure (HF), and patient QoL (Kansas City Cardiomyopathy Questionnaire [KCCQ] score compared to baseline, and increase in KCCQ score ≥ 5 points) that were published during January 2000-August 2022. The meta-analysis was performed using the inverse variance method and random-effects model. INPLASY registration: INPLASY202290023., Results: Sixteen studies (9 recent RCTs) were included, and a total of 16,710 HFmrEF or HFpEF patients were enrolled. SGLT2 inhibitors significantly reduced composite cardiovascular outcome (CV death/HHF/urgent visit for HF; pooled hazard ratio [HR]: 0.80, 95% confidence interval [95%CI]: 0.74-0.86) and HHF alone (HR: 0.74, 95%CI: 0.67-0.82), but there was no significant reduction in CV death alone (HR: 0.93, 95%CI: 0.82-1.05). Benefit of SGLT2 inhibitors for decreasing CV death/HHF was observed across all subgroups, including left ventricular ejection fraction (LVEF) range, diabetes status, New York Heart Association functional class, and baseline renal function. For total HHF, SGLT2 inhibitors conferred benefit in both LVEF 50-60% (HR: 0.64, 95%CI: 0.54-0.76), and LVEF >60% (HR: 0.84, 95%CI: 0.71-0.98). Significant change was observed in the KCCQ-clinical summary score compared to baseline (mean difference: 1.33, 95%CI: 1.31-1.35), and meaningful improvement in QoL was shown across all 3 types of increase in KCCQ score ≥ 5 points., Conclusion: This study demonstrates the benefits of SGLT2 inhibitors for improving cardiovascular outcomes and QoL in HFmrEF or HFpEF patients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Treewaree, Kulthamrongsri, Owattanapanich and Krittayaphong.)

Background: Congenital central hypoventilation syndrome (CCHS) is a rare condition caused by mutations in the Paired-Like Homeobox 2B (PHOX2B) gene. It causes alveolar hypoventilation and autonomic dysregulation. This report aimed to raise awareness of this rare cause of neonatal apnea and hypoventilation as well as described the diagnostic work up to confirm the diagnosis in resource-limited setting where polysomnography for neonate is unavailable., Case Presentation: A late preterm female newborn born from a non-consanguineous primigravida 31-year-old mother had desaturation soon after birth followed by apnea and bradycardia. After becoming clinically stable, she still had extubation failure from apnea without hypercapnic ventilatory response which worsened during non-rapid eye movement (NREM) sleep. After exclusion of other etiologies, we suspected congenital central hypoventilation syndrome and sent genetic testing. The result showed a PHOX2B gene mutation which confirmed the diagnosis of CCHS. We gave the patient's caregivers multidisciplinary home respiratory care training including tracheostomy care, basic life support, and simulation training for respiratory problem solving. Then, the patient was discharged and scheduled for follow-up surveillance for associated conditions., Conclusion: Diagnosis of CCHS in neonates includes the main clue of the absence of hypercapnic ventilatory response which worsens during non-rapid eye movement (NREM) sleep after exclusion of other causes. Molecular testing for PHOX2B gene mutation was used to confirm the diagnosis., (© 2022. The Author(s).)
