Meta-Analysis
In observational studies, gastroesophageal reflux disease (GERD) is linked to atrial fibrillation (AF). It is uncertain whether the relationship is due to GERD-induced AF or GERD caused by AF, or confusion with factors related to GERD and AF such as obesity and sleep-disordered breathing. We applied bidirectional Mendelian randomization (MR), in which genetic variations are used as instrumental variables to resolve confounding and reverse causation issues, to determine the causal effect between GERD and AF. Using summary data from the GERD and AF genome-wide association study (GWAS), a bidirectional MR was performed to estimate the causative impact of GERD on AF risk and AF on GERD risk. The GWAS of GERD meta-analysis comprised 78707 cases and 288734 controls. GWAS summary data for AF, including 45766 AF patients and 191924 controls, were used to genetically predicted AF. The inverse variance weighted (IVW) method was the major MR approach used. MR-PRESSO was implemented to detect heterogeneity and correct the effect of outliers. Weighted median and MR-Egger regression were applied to test heterogeneity and pleiotropy. The genetic instruments of GERD related to increasing the risk of AF, with an OR of 1.339 (95% CI: 1.242-1.444, < 0.001). However, after removing the outlier 8 SNPs, genetically predicted AF was not associated with an elevated risk of GERD ( = 0.351). Our result suggested that GERD had a causal effect on AF. However, no evidence was identified that AF elevated the risk of GERD.

OBJECTIVE
To develop a robust machine learning prediction model for the automatic screening and diagnosis of obstructive sleep apnea (OSA) using five advanced algorithms, namely Extreme Gradient Boosting (XGBoost), Logistic Regression (LR), Support Vector Machine (SVM), Light Gradient Boosting Machine (LightGBM), and Random Forest (RF) to provide substantial support for early clinical diagnosis and intervention.
METHODS
We conducted a retrospective analysis of clinical data from 439 patients who underwent polysomnography at the Affiliated Hospital of Xuzhou Medical University between October 2019 and October 2022. Predictor variables such as demographic information [age, sex, height, weight, body mass index (BMI)], medical history, and Epworth Sleepiness Scale (ESS) were used. Univariate analysis was used to identify variables with significant differences, and the dataset was then divided into training and validation sets in a 4:1 ratio. The training set was established to predict OSA severity grading. The validation set was used to assess model performance using the area under the curve (AUC). Additionally, a separate analysis was conducted, categorizing the normal population as one group and patients with moderate-to-severe OSA as another. The same univariate analysis was applied, and the dataset was divided into training and validation sets in a 4:1 ratio. The training set was used to build a prediction model for screening moderate-to-severe OSA, while the validation set was used to verify the model's performance.
RESULTS
Among the four groups, the LightGBM model outperformed others, with the top five feature importance rankings of ESS total score, BMI, sex, hypertension, and gastroesophageal reflux (GERD), where Age, ESS total score and BMI played the most significant roles. In the dichotomous model, RF is the best performer of the five models respectively. The top five ranked feature importance of the best-performing RF models were ESS total score, BMI, GERD, age and Dry mouth, with ESS total score and BMI being particularly pivotal.
CONCLUSION
Machine learning-based prediction models for OSA disease grading and screening prove instrumental in the early identification of patients with moderate-to-severe OSA, revealing pertinent risk factors and facilitating timely interventions to counter pathological changes induced by OSA. Notably, ESS total score and BMI emerge as the most critical features for predicting OSA, emphasizing their significance in clinical assessments. The dataset will be publicly available on my Github.

Heartburn is a common symptom shared by both gastroesophageal reflux disease (GERD) and functional heartburn (FHB), which can make it challenging to differentiate between the two conditions. However, examining oral manifestations of GERD can be a cost-effective and readily available method to aid in this differentiation process. It may serve as a valuable tool in distinguishing GERD from FHB.

We present a case of a woman in her 60s, with a history of a gastric sleeve resection, over 50% excess body weight loss, and subsequent severe gastroesophageal reflux disease refractory to maximal medical therapy, who underwent a conversion of a sleeve gastrectomy to a Roux-en-Y gastric bypass with hiatal hernia repair. On postoperative day five, she was evaluated at our emergency department for vomiting and inability to tolerate oral intake. Imaging revealed a large retrocardiac hiatal hernia and extraluminal contrast extravasation. She was taken to the operating room after resuscitation, where the gastric pouch and roux limb were found to have significant edema with recurrence of the hernia. This was able to be reduced and a frank perforation was found at the posterior aspect of the anastomosis. A covered metal stent was placed by the gastroenterologist and drains were left in place. In the ICU, nasojejunal feeds were stopped given suspicion of backflow with persistent leak. A decision was made to remove the stent and place an endoluminal vacuum (endoscopic vacuum-assisted wound closure [EVAC]). After three subsequent vacuum-sponge changes, the perforation was found to have healed. Patient was tolerating a diet on discharge. This case is an example of a complication where a multidisciplinary approach to a difficult leak resulted in recovery with the use of EVAC. We believe this is a valuable tool to have in our armamentarium for difficult-to-manage leaks.

Gastroesophageal reflux disease (GERD) is one of the most common problems encountered in outpatient general medicine and gastroenterology clinics. GERD may present with classic esophageal symptoms, extraesophageal symptoms, or mixed symptoms. The diagnosis and treatment of GERD are challenging due to the variety of symptoms and multifactorial pathophysiology. Since there is no consensus on the diagnosis and treatment of GERD in Saudi Arabia, the Saudi Gastroenterology Association established an expert group to formulate a consensus on the clinical care pathway for the diagnosis and treatment of GERD to update health-care providers in Saudi Arabia. The expert group reviewed the literature including recently published international guidelines, clinical trials, and expert opinion and conducted virtual and in-person meetings. A total of 22 statements on the definition, diagnosis, and treatment of GERD were formulated, and three algorithms for the clinical care of GERD were developed with a detailed description for each step. The expert group endorsed the new definition of GERD, the practical principles of interpretation of the diagnostic GERD evaluation, and the practical guidance for GERD treatment including medical, surgical, and endoscopic therapy. The expert group recommends further studies to investigate local data on the diagnosis and treatment of GERD.

BACKGROUND
Most endoscopic anti-reflux interventions for gastroesophageal reflux disease (GERD) management are technically challenging to practice with inadequate data to support it utility. Therefore, this study was carried to evaluate the effectiveness and safety newer endoscopic full-thickness fundoplication (EFTP) device along with Argon Plasma Coagulation to treat individuals with GERD.
AIM
To evaluate the effectiveness and safety newer EFTP device along with Argon Plasma Coagulation to treat individuals with GERD.
METHODS
This study was a single-center comparative analysis conducted on patients treated at a Noble Institute of Gastroenterology, Ahmedabad, hospital between 2020 and 2022. The research aimed to retrospectively analyze patient data on GERD symptoms and proton pump inhibitor (PPI) dependence who underwent EFTP using the GERD-X system along with argon plasma coagulation (APC). The primary endpoint was the mean change in the total gastroesophageal reflux disease health-related quality of life (GERD-HRQL) score compared to the baseline measurement at the 3-month follow-up. Secondary endpoints encompassed enhancements in the overall GERD-HRQL score, improvements in GERD symptom scores at the 3 and changes in PPI usage at the 3 and 12-month time points.
RESULTS
In this study, patients most were in Hill Class II, and over half had ineffective esophageal motility. Following the EFTP procedure, there were significant improvements in heartburn and regurgitation scores, as well as GERD-HRQL scores ( < 0.001). PPI use significantly decreased, with 82.6% not needing PPIs or prokinetics at end of 1 year. No significant adverse events related to the procedures were observed in either group.
CONCLUSION
The EFTP along with APC procedure shows promise in addressing GERD symptoms and improving patients' quality of life, particularly for suitable candidates. Moreover, the application of a lone clip with APC yielded superior outcomes and exhibited greater cost-effectiveness.

BACKGROUND/AIM
Congenital anomalies of the kidney and urinary tract(CAKUT) are the leading causes of childhood chronic kidney disease (CKD). The etiology of most of the cases is thought to be multifactorial. In this study, risk factors for CAKUT and the effect of mobile phone-related electromagnetic field (EMF) exposure during pregnancy were investigated.
MATERIALS AND METHODS
Fifty-seven cases and 57 healthy controls under 2 years of age were included and their mothers were subjected to a questionnaire. Groups were compared for parents' demographics, pregestational (chronic disease, body mass index, use of the folic acid supplements) and antenatal variables (gestational disease, weight gain during pregnancy,) and exposures during pregnancy. To assess mobile phone-related radiation exposure, all participants were asked about their daily call time, the proximity of the phone when not in use, and the models of their mobile phones. The specific absorption rate (SAR) of the mobile phones and the effective SAR value (SAR × call time) as an indicator of EMF exposure were recorded.
RESULTS
Excess weight gain according to BMI during pregnancy was related to an increased risk of CAKUT (p=0.012). Folic acid use before pregnancy was protective for CAKUT (p = 0.028). The call time of mothers of the CAKUT group was significantly longer than the control (p = 0.001). An association was observed between higher effective SAR values and increased risk of CAKUT (p = 0.03). However the proximity of the mobile phone to the mother's body when not in use was not found as a risk factor.
CONCLUSION
The etiology of CAKUT is multifactorial. Our results suggest that prolonged phone call and higher EMF exposure during pregnancy increases the risk of CAKUT in the offspring.

BACKGROUND
Gastroesophageal reflux disease (GERD) is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage. Wendan Decoction (WDD) is a traditional Chinese herbal formula used to treat various gastrointestinal disorders, such as gastritis, functional dyspepsia, and irritable bowel syndrome. Mosapride, a prokinetic agent, functions as a selective 5-hydroxytryptamine 4 agonist, enhancing gastrointestinal motility.
AIM
To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.
METHODS
Eighty patients with GERD were randomly divided into treatment (receiving WDD combined with mosapride) and control (receiving mosapride alone) groups. The treatment was conducted from January 2021 to January 2023. The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire (RDQ). The secondary outcomes were improved esophageal motility (measured using esophageal manometry), gastric emptying (measured using gastric scintigraphy), and quality of life [measured the Short Form-36 (SF-36) Health Survey].
RESULTS
The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters, such as lower esophageal sphincter pressure, peristaltic amplitude, and peristaltic velocity compared to the control group. The treatment group showed significantly higher gastric emptying rates and SF-36 scores (in both physical and mental domains) compared to the control group. No serious adverse effects were observed in either group.
CONCLUSION
WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery. It can improve GERD symptoms, esophageal motility, gastric emptying, and the quality of life of patients. Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.

An air embolism is characterized by the entry of gas bubbles into the circulatory system, which can lead to the possible occlusion of blood vessels, posing a potentially life-threatening risk. While commonly associated with lung trauma or decompression sickness, it can also result from medical procedures such as central venous catheter insertion or, in our case, gas insufflation for laparoscopic surgery. We present the case of a 65-year-old female who suffered from a stroke secondary to an air embolism after undergoing a laparoscopic Nissen fundoplication in which carbon dioxide insufflation of the abdominal cavity was utilized. We also will discuss the elusive etiology of this complication as well as diagnosis, treatment, and proposed preventative measures. A 65-year-old female with gastroesophageal reflux disease and a hiatal hernia elected to undergo a laparoscopic Nissen fundoplication for hernia repair. After a successful surgery, the patient was found with significant neurological deficits, including left-sided hemiplegia, numbness in the left hand, hemianopsia, dysarthria, and a National Institutes of Health Stroke Scale score of 20. CT head imaging revealed several low-density foci in the right frontal lobe, while CT neck and chest imaging revealed subcutaneous emphysema and pneumomediastinum. Subsequent labs were significant for an elevated lactate at 7.6 mmol/L. MRI of the brain depicted evidence of an acute infarct in the right frontal lobe with diffusion-weighted imaging (DWI) sequences. The imaging results were correlated with the patient's clinical presentation to establish the diagnosis of a nondominant hemisphere stroke, localized to an anterior branch of the right middle cerebral artery (MCA). After intubation and supportive treatment for three days, the patient was extubated and able to follow commands but had left facial weakness and diminished strength in the left upper and lower extremities. At the two-month follow-up visit, the patient no longer had any focal neurological deficits. Air emboli, though very rare, can occur as a complication in laparoscopic surgeries that utilize CO for body cavity insufflation. Patients may be asymptomatic with small, self-limiting emboli, while others may exhibit pulmonary symptoms, cardiac arrest, or focal neurologic changes, depending on the emoji's size and location. Given the wide range of patient presentations, the elevated mortality of laparoscopic procedures complicated by air emboli, and the rare occurrence of focal neurological symptoms as depicted in this case, rapid diagnosis and close postoperative observation and treatment are vital for both short-term and long-term patient outcomes.

Introduction Laryngopharyngeal reflux (LPR) is a condition characterized by the backflow of gastric contents rising through the esophagus, affecting the aerodigestive tract and leading to throat symptoms such as hoarseness, chronic cough, and throat clearing. LPR is recognized as a separate condition from gastroesophageal reflux disease, despite the fact that they both involve the backflow of the stomach contents as their primary pathology. Our study aimed to evaluate the prevalence of LPR within the population of Saudi Arabia. Methods A cross-sectional study was conducted using an electronic questionnaire from August to November 2023, involving participants from all five regions of Saudi Arabia. A total of 1140 participants completed the questionnaire, which included the Reflux Symptom Index (RSI) to assess the prevalence of LPR. Results LPR was found to be prevalent in 31.2% of the study population, with the most common associated demographics being female gender (p = 0.032) and adults aged 36-45 years (p = 0.006). However, no significant relationship was observed based on region of residence or other demographic factors such as education level or occupation. Conclusion LPR has a high prevalence in the population of Saudi Arabia. Therefore, further research and awareness about this condition are warranted to better understand its impact, improve diagnosis, and develop appropriate management strategies.
