The association between night eating syndrome and GERD symptoms among university students at An-Najah National University in Palestine: a cross-sectional study.

BACKGROUND: Night eating syndrome (NES) is a kind of eating disorder. NES association with gastroesophageal reflux disease (GERD) symptoms among university students is still not fully understood. We aimed to determine the relationship between NES and the presence of GERD symptoms among university students at An-Najah National University in Palestine. METHODS: This study involved undergraduate students from An-Najah National University. The data were collected through online surveys from November to December 2023. The sampling frame involved voluntary sampling, as the data were collected using a structured questionnaire to collect data on sociodemographic variables, medical history, lifestyle habits, nutritional status, GERD risk, and NES. The GERD questionnaire (GerdQ) was used to assess symptoms, while the Arabic version of the validated Night Eating Questionnaire (NEQ) was used to assess night eating. Physical activity was assessed using the short form of the International Physical Activity Questionnaire (SF-IPAQ), and adherence to a Mediterranean diet was assessed using the validated Arabic version of the MEDAS. Both univariate and multivariate analyses were also conducted to assess the study hypotheses. RESULTS: The study involved 554 participants, 59.9% female. A total of 33.4% reported GERD symptoms, with 10.3% having NES. A strong association was observed between GERD and NES and between GERD and physical activity. Night eating syndrome (AOR = 2.84, CI = 1.07-3.19), high physical activity (AOR = 0.473, CI = 1.05-3.19), and non-smoking (AOR = 0.586, CI = 1.27-7.89) were identified as independent predictors of GERD symptoms. CONCLUSION: This study revealed that 33.4% of undergraduate students were at risk of GERD, with night eaters having a greater risk. GERD risk was negatively associated with physical activity level and smoking status. No associations were found between GERD risk and weight status, Mediterranean diet adherence, sociodemographic factors, or sleep disturbances.

Risk indicators for the severity of erosive wear in deciduous dentition of Mexican schoolchildren aged 5 to 7 years.

The objective of this work was to estimate the prevalence and severity of erosive tooth wear (ETW), and to identify risk indicators of deciduous dentition of a group of schoolchildren from public schools in Tlalnepantla de Baz, State of Mexico. A cross-sectional study was carried out in 352 schoolchildren from 5 to 7 years old. The severity of the ETW was evaluated using the Basic Erosive Wear Examination (BEWE). Risk indicators were evaluated through a survey which included food and beverage consumption, consumption habits, vitamin C consumption, gastroesophageal reflux, heartburn, belching, xerostomia, vomiting and teeth grinding. Multinomial logistic regression models were fitted. The prevalence of ETW was 99.7% (n = 351). Regarding severity, 46.6% were at a null/mild level, 27.3% moderate, and 26.1% severe. Males were more likely to present severe ETW (odds ratio (OR) = 2.23, 95% confidence interval (CI), 1.27-3.93; p = 0.005). The risk indicators for the severity of ETW were the frequent consumption of citrus fruits (OR = 2.09, 95% CI, 1.12-3.89; p = 0.021), fruit juice (OR = 1.99, 95% CI, 1.06-3.75; p = 0.033), processed beverages (OR = 2.15, 95% CI, 1.23-3.78; p = 0.008) and hot sauce (OR = 1.82, 95% CI, 1.03-3.20; p = 0.036). The prevalence of ETW in the deciduous dentition was very high (99.7%) and ~1/3 for severe ETW. The dietary factors associated with severe ETW are part of the regular consumption of Mexican school-age children, which impact their oral health condition. It is important to establish intervention strategies from the infant stage, focused on both children and their caregivers.

Sex difference in the associations among risk factors with gastroesophageal reflux disease in a large Taiwanese population study.

BACKGROUND: Gastroesophageal reflux disease (GERD) is a common global health issue. Previous studies have revealed a higher prevalence of GERD in females than in males, however few studies have investigated sex differences in the risk factors associated with GERD. Therefore, the aim of this population-based study was to examine sex differences in the risk factors for GERD in a large cohort of over 120,000 Taiwanese participants. METHODS: We enrolled 121,583 participants (male: 43,698; female: 77,885; mean age 49.9 ± 11.0 years) from the Taiwan Biobank. The presence of GERD was ascertained using self-reported questionnaires. Sex differences in the risk factors associated with GERD were examined using multivariable logistic regression analysis. RESULTS: The overall prevalence of GERD was 13.7%, including 13.0% in the male participants and 14.1% in the female participants (p < 0.001). Multivariable analysis showed that older age, hypertension, smoking history, alcohol history, low fasting glucose, and low uric acid were significantly associated with GERD in the male participants. In the female participants, older age, diabetes, hypertension, smoking history, alcohol history, low systolic blood pressure, low fasting glucose, high hemoglobin, high total cholesterol, low high-density lipoprotein cholesterol (HDL-C), low low-density lipoprotein cholesterol, and low uric acid were significantly associated with GERD. Significant interactions were found between sex and age (p < 0.001), diabetes (p < 0.001), smoking history (p < 0.001), fasting glucose (p = 0.002), triglycerides (p = 0.001), HDL-C (p = 0.001), and estimated glomerular filtration rate (p = 0.002) on GERD. CONCLUSIONS: Our results showed a higher prevalence of GERD among females compared to males. Furthermore, sex differences were identified in the risk factors associated with GERD, and older age, diabetes, smoking history, and low HDL-C were more closely related to GERD in females than in males.

Asthma and obstructive sleep apnea: Unveiling correlations and treatable traits for comprehensive care.

Asthma and obstructive sleep apnea (OSA) are common respiratory disorders. They share characteristics such as airway obstruction, poor sleep quality, and low quality of life. They are often present as comorbidities, along with obesity, gastroesophageal reflux disease (GERD), and allergic rhinitis (AR), which impacts the disease's control. In recent years, there has been discussion about the association between these conditions and their pathophysiological and clinical consequences, resulting in worse health outcomes, increased healthcare resource consumption, prolonged hospital stays, and increased morbidity and mortality. Some studies demonstrate that treatment with continuous positive airway pressure (CPAP) can have a beneficial effect on both pathologies. This review summarizes the existing evidence of the association between asthma and OSA at their pathophysiological, epidemiological, clinical, and therapeutic levels. It intends to raise awareness among healthcare professionals about these conditions and the need for further research.

Gastroesophageal reflux disease and atrial fibrillation: a bidirectional Mendelian randomization study.

Background: 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. Methods: 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. Results: The genetic instruments of GERD related to increasing the risk of AF, with an OR of 1.339 (95% CI: 1.242-1.444, p < 0.001). However, after removing the outlier 8 SNPs, genetically predicted AF was not associated with an elevated risk of GERD (p = 0.351). Conclusions: Our result suggested that GERD had a causal effect on AF. However, no evidence was identified that AF elevated the risk of GERD.

Gastroesophageal reflux disease symptoms and risk of atrial fibrillation in a population-based cohort study (the HUNT study).

AIMS: Gastroesophageal reflux disease (GERD) may influence the risk of atrial fibrillation (AF). We investigated the association between symptoms of GERD and AF in the Trøndelag Health Study (HUNT). METHODS: The study cohort comprised 34,120 adult men and women initially free of AF with information on GERD symptoms. Participants were followed from the baseline clinical examination (1 October 2006 to 30 June 2008) to March 31, 2018. RESULTS: During a median follow-up of 8.9 years, 1,221 cases of AF were diagnosed. When looking at the whole population, participants with much GERD symptoms did not have an increased risk of AF (HR: 1.01; CI: 95%, 0.82 to 1.24) while participants with little GERD symptoms had a 14% lower risk of AF compared those with no GERD symptoms (HR: 0.86; CI: 95%, 0.76 to 0.97). Among younger participants (<40 years of age), the risk of AF had a trend towards increased risk with increasing symptom load of GERD (little GERD symptoms, HR: 3.09; CI: 95%, 0.74 to 12.94 and much GERD symptoms, HR: 5.40; 95% CI: 0.82 to 35.58). Among older participants (≥65 years of age), we saw a slightly reduced risk of AF in participants with little symptoms (HR: 0.84; CI: 0.72 to 0.97) and no association among those with much GERD symptoms (HR: 1.06; 95% CI: 0.82 to 1.36). CONCLUSION: We did not find support for a clinically important association between symptoms of GERD and AF across all age groups but for some younger people, GERD might play a role in the development of AF. However, our estimates for this age group were very imprecise and larger studies including younger individuals are warranted.

Interstitial Lung Disease and Progressive Pulmonary Fibrosis: a World Trade Center Cohort 20-Year Longitudinal Study.

PURPOSE: World Trade Center (WTC) exposure is associated with obstructive airway diseases and sarcoidosis. There is limited research regarding the incidence and progression of non-sarcoidosis interstitial lung diseases (ILD) after WTC-exposure. ILD encompasses parenchymal diseases which may lead to progressive pulmonary fibrosis (PPF). We used the Fire Department of the City of New York's (FDNY's) WTC Health Program cohort to estimate ILD incidence and progression. METHODS: This longitudinal study included 14,525 responders without ILD prior to 9/11/2001. ILD incidence and prevalence were estimated and standardized to the US 2014 population. Poisson regression modeled risk factors, including WTC-exposure and forced vital capacity (FVC), associated with ILD. Follow-up time ended at the earliest of incident diagnosis, end of study period/case ascertainment, transplant or death. RESULTS: ILD developed in 80/14,525 FDNY WTC responders. Age, smoking, and gastroesophageal reflux disease (GERD) prior to diagnosis were associated with incident ILD, though FVC was not. PPF developed in 40/80 ILD cases. Among the 80 cases, the average follow-up time after ILD diagnosis was 8.5 years with the majority of deaths occurring among those with PPF (PPF: n = 13; ILD without PPF: n = 6). CONCLUSIONS: The prevalence of post-9/11 ILD was more than two-fold greater than the general population. An exposure-response gradient could not be demonstrated. Half the ILD cases developed PPF, higher than previously reported. Age, smoking, and GERD were risk factors for ILD and PPF, while lung function was not. This may indicate that lung function measured after respirable exposures would not identify those at risk for ILD or PPF.

Bidirectional correlation between gastroesophageal reflux disease and sleep problems: a systematic review and meta-analysis.

Objectives: Gastroesophageal reflux disease (GERD) and sleep problems are highly prevalent among the general population. Both them are associated with a variety of psychiatric disorders such as depression and anxiety, which is highlighting an underexplored connection between them. This meta-analysis aims to explore the association between sleep problems and GERD. Methods: We conducted a comprehensive search on PubMed, Cochrane Library, Embase, and Web of Science, using Medical Subject Headings (MeSH) and keywords, covering articles from the inception of the databases until August 2023. Stata statistical software, version 14.0, was utilized for all statistical analyses. A fixed-effects model was applied when p > 0.1 and I2 ≤ 50%, while a random-effects model was employed for high heterogeneity (p < 0.1 and I2 > 50%). Funnel plots and Egger's test were used to assess publication bias. Results: Involving 22 studies, our meta-analysis revealed that insomnia, sleep disturbance, or short sleep duration significantly increased the risk of GERD (OR = 2.02, 95% CI [1.64-2.49], p < 0.001; I2 = 66.4%; OR = 1.98, 95% CI [1.58-2.50], p < 0.001, I2 = 50.1%; OR = 2.66, 95% CI [2.02-3.15], p < 0.001; I2 = 62.5%, respectively). GERD was associated with an elevated risk of poor sleep quality (OR = 1.47, 95% CI [1.47-1.79], p < 0.001, I2 = 72.4%), sleep disturbance (OR = 1.47, 95% CI [1.24-1.74], p < 0.001, I2 = 71.6%), or short sleep duration (OR = 1.17, 95% CI [1.12-1.21], p < 0.001, I2 = 0). Conclusion: This meta-analysis establishes a bidirectional relationship between four distinct types of sleep problems and GERD. The findings offer insights for the development of innovative approaches in the treatment of both GERD and sleep problems.

A Mendelian randomization analysis identifies causal association between sarcopenia and gastroesophageal reflux disease.

The incidence of gastroesophageal reflux disease (GERD) is increasing with the advancement of world population aging, affecting the population health worldwide. Recently, there were several researches to suggest the association between GERD and sarcopenia, but evidence supporting the causal effect was absent. The purpose of this study is to determine the causal relationship between GERD and sarcopenia through a Mendelian randomization (MR) study. We conducted an MR analysis by using summary-level data of genome-wide association studies (GWASs) in the European population. The inverse variance weighted (IVW) method was used as the primary analytical method for evaluating causality. In addition, four other MR methods were performed to supplement the IVW results. We also used the Mendelian randomization pleiotropy residual sum and outlier (MR-PRESSO) and the multivariable Mendelian randomization (MVMR) to validate the robustness of our results. IVW analysis revealed a causally positive correlation between low hand grip strength (OR = 1.2358, 95% C.I.: 1.0521-1.4514, P = 0.0099), decreased walking pace (OR = 0.1181, 95% C.I.: 0.0838-0.1666, P = 4×10-34), and decreased appendicular lean mass (ALM) (OR = 0.8612, 95% C.I.: 0.8263-0.8975, P = 1×10-12) and GERD. MR-PRESSO and MVMR analysis confirmed the association evidence. In conclusion, this MR analysis supported the causal association between sarcopenia-related traits and GERD.

Prevalence and causes of chronic cough in Japan.

BACKGROUND: Chronic cough is one of the most common symptoms of respiratory diseases and can adversely affect patients' quality of life and interfere with social activities, resulting in a significant social burden. A survey is required to elucidate the frequency and treatment effect of chronic cough. However, clinical studies that cover all of Japan have not yet been conducted. METHODS: Patients who presented with a cough that lasted longer than 8 weeks and visited the respiratory clinics or hospitals affiliated with the Japan Cough Society during the 2-year study period were registered. RESULTS: A total of 379 patients were enrolled, and those who did not meet the definition of chronic cough were excluded. A total of 334 patients were analyzed: 201 patients had a single cause, and 113 patients had two or more causes. The main causative diseases were cough variant asthma in 92 patients, sinobronchial syndrome (SBS) in 36 patients, atopic cough in 31 patients, and gastroesophageal reflux (GER)-associated cough in 10 patients. The time required to treat undiagnosed patients and those with SBS was significantly longer and the treatment success rate for GER-associated cough was considerably poor. CONCLUSIONS: We confirmed that the main causes of chronic cough were cough variant asthma, SBS, atopic cough, and their complications. We also showed that complicated GER-associated cough was more likely to become refractory. This is the first nationwide study in Japan of the causes and treatment effects of chronic cough.

Analyzing the correlation between gastroesophageal reflux disease and anxiety and depression based on ordered logistic regression.

Numerous studies have indicated a connection between psychiatric symptoms, specifically anxiety and depression, and gastroesophageal reflux. However, the precise nature of the link between the severity of gastroesophageal reflux disease and the severity of anxiety and depression remains uncertain. Here, we gathered 24-h pH monitoring data and baseline patient information from a cohort of 518 individuals. Additionally, we evaluated their psychological well-being using the Hospital Anxiety and Depression Scale. The relationship between baseline characteristics and varying degrees of anxiety, depression, and gastroesophageal reflux disease (GERD) was assessed using R software version 4.1.3 and logistic regression models. The findings indicate a statistically significant variation in anxiety levels based on gender, as well as a significant disparity in depression groups when considering age and literacy levels. Kruskal-Wallis test analysis revealed a significant positive correlation between the severity of anxiety and depression and the 24-h pH monitoring results in our patient cohort. As the anxiety and depression levels increased, the rank mean for each examination result also increased. Logistic regression modeling analysis showed that a higher anxiety level was associated with a higher level of GERD. In the presence of mild anxiety, there is a statistically significant association with a higher incidence of GERD with an odds ratio (OR) of 2.64 (95% CI 1.50, 4.64). Similarly, the moderately severe anxiety group also exhibits a causal relationship with an increased GERD incidence, with an OR of 6.84 (95% CI 3.92, 12.17). Additionally, moderate to severe depression is associated with a higher incidence of GERD, with an OR of 2.32 (95% CI 1.23, 4.37). The prevalence of GERD was greater among males compared to females (OR 2.29, 95% CI 1.51-3.49). Additionally, an elevated body mass index (BMI) demonstrated a positive correlation with the susceptibility to GERD (OR 1.07, 95% CI 1.01-1.14). Increasing age may promote the occurrence of GERD in patients. These findings may help to provide a better basis for psychological or pharmacological interventions for GERD patients with psychosomatic symptoms in the future, and provide a reference basis for clinical treatment of the disease.

Comorbidities associated with adult asthma: a population-based matched cohort study in Finland.

BACKGROUND: Asthma is a common chronic disease characterised by variable respiratory symptoms and airflow limitation, affecting roughly 4%-10% of the adult population. Adult asthma is associated with higher all-cause mortality compared to individuals without asthma. In this study, we investigate the comorbidities that may affect the management of asthma. METHODS: Total of 1648 adults with asthma and 3310 individuals without asthma aged 30-93 were matched with age, gender and area of residency, and followed from 1 January 1997 to 31 December 2013. Baseline information was collected with questionnaires 1997 and follow-up register data from the national discharge registry Finnish Institute for Health and Welfare. Data included diagnoses from outpatient care and day surgery of specialised health care, and data from inpatient care of specialised and primary health care. We included all main diagnoses that had at minimum 200 events and number of diagnoses based on their common appearance with adult asthma. RESULTS: The mean follow-up time varied between 14.2 and 15.1 years, and age at the time of enrolment was 53.9 years for subjects without asthma and 54.4 years for patients with asthma. Chronic obstructive pulmonary disease was 10 times more common among asthmatics. Risk of acute rhinosinusitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis and vocal cord dysfunction was fourfold and risk of pneumonia, and chronic rhinosinusitis was 2.5 times more common among asthmatics. Sleep apnoea, gastro-oesophageal reflux disease, diabetes, allergic rhinitis and dysfunctional breathing were twofold and cataract nearly twofold higher in the asthmatic group. Adult asthma was also significantly associated with musculoskeletal diseases, incontinence and bronchiectasis. CONCLUSIONS: The most common and most severe comorbidity of adult asthma in this study was chronic obstructive pulmonary disease. Other common comorbidities of adult asthma include acute rhinosinusitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis, allergic rhinitis, dysfunctional breathing, diabetes, pneumonia, sleep apnoea and gastro-oesophageal reflux disease.

Applying Lyon consensus criteria in the work-up of patients with extra-oesophageal symptoms - A multicentre retrospective study.

BACKGROUND: The diagnosis of gastro-oesophageal reflux disease (GERD) based on otolaryngologist's assessment of laryngoscopic findings remains contentious in terms of sensitivity and specificity. AIMS: To evaluate GERD prevalence, applying Lyon 2.0 Consensus criteria, in patients with extra-oesophageal symptoms undergoing laryngoscopic examination and impedance-pH monitoring. METHODS: In this retrospective assessment, we included 470 patients with extra-oesophageal symptoms, either isolated or combined with typical symptoms, who had been referred to six tertiary Italian Gastroenterology Units between January and December 2020. Of these, 274 underwent 24-h impedance-pH monitoring and laryngoscopy off PPI therapy. GERD diagnosis followed Lyon Consensus 2.0 criteria, incorporating mean nocturnal baseline impedance when pH-impedance monitoring was inconclusive. RESULTS: Laryngoscopic examination revealed pathological findings (predominantly posterior laryngitis) in 71.2% (195/274). GERD was diagnosed in 29.2% (80/274) via impedance-pH monitoring. The prevalence of GERD in patients with positive or negative laryngoscopy was similar (32.3% vs. 21.5%, p = 0.075). No significant difference in proximal reflux occurrences was noted between positive and negative laryngoscopy groups (33.3% vs. 24.1%, p = 0.133). Laryngoscopy demonstrated sensitivity and specificity of 78.8% and 32.0%, respectively, with a positive predictive value (PPV) of 32.3% and negative predictive value (NPV) of 28.4%. In contrast, a threshold of four concurrent laryngoscopic signs, identified in only eight patients, demonstrated a PPV of 93.8% and a NPV of 73.6% (sensitivity 25.4%, specificity 99.2%). CONCLUSION: This study underscores the limited diagnostic accuracy of laryngoscopy, emphasising the necessity of impedance-pH monitoring for confirming GERD diagnoses using Lyon 2.0 criteria in patients with suspected extra-oesophageal symptoms.

Long-term risk factors for developing Barrett's oesophagus in patients with gastro-oesophageal reflux disease: a longitudinal cohort study.

BACKGROUND AND AIMS: Several characteristics are known to affect the risk of Barrett's oesophagus (BO) in the general population, with symptomatic gastro-oesophageal reflux disease (GORD) being a critical risk factor. In this study, we examined factors that influence BO development in people living with GORD. DESIGN: People living with GORD were recruited from an endoscopy unit with lifestyle, medical and prescribing history collected. Logistic regression analysis was undertaken to assess the effects of multiple parameters on the likelihood of developing BO. RESULTS: 1197 participants were recruited. Most were Caucasian (n=1188, 99%), had no formal educational qualifications (n=714; 59.6%) and lived with overweight (mean body mass index >25 kg/m2). Many lived in areas of least socioeconomic resource (n=568; 47.4%). 139 (11.6%) had BO at baseline. In adjusted baseline analysis (n=1197), male sex (adjusted OR, aOR 2.04 (95% CI 1.92 to 4.12), p≤0.001), increasing age (aOR 1.03 (95% CI 1.01 to 1.04), p≤0.0001) and proton pump inhibitor use (aOR 3.03 (95% CI 1.80 to 5.13), p≤0.0001) were associated with higher odds of BO. At follow-up (n=363), 22 (6.1%) participants developed BO; male sex (aOR 3.18 (95% CI 1.28 to 7.86), p=0.012), pack-years cigarettes smoked (aOR 1.04 (95% CI 1.00 to 1.08), p=0.046) and increased alcohol intake (aOR 1.02 (95% CI 1.00 to 1.04), p=0.013), were associated with increased odds of BO. CONCLUSION: Male sex, pack-years cigarettes smoked, and increasing alcohol intake, were independently associated with increased odds of developing BO over 20-year follow-up. These results align with research linking male sex and smoking with BO and extend this by implicating the potential role of alcohol in developing BO, which may require communication through public health messaging.

Impact of Gender on Gastroesophageal Reflux Disease Complications: Analysis of 27 Million Hospitalizations.

BACKGROUND AND AIMS: Previous studies have reported gender differences in patients with gastroesophageal reflux disease (GERD). These studies have also reported differences based on gender in the rates of complications. In this study, we aim to identify gender disparities in the rates of GERD complications in the United States. METHODS: We queried the 2016-2020 National Inpatient Sample database to identify patients with GERD. Patients with eosinophilic esophagitis or missing demographics were excluded. We compared patient demographics, comorbidities and complications based on gender. Multivariate logistic regression analysis was used to identify the impact of gender on complications of GERD. RESULTS: 27.2 million patients were included in the analysis. Out of them, 58.4% of the hospitalized patients with GERD were female. Majority of the women were White (75%), aged>65 years (57.5%) and were in the Medicare group (64%). After adjusting for confounders, females were noted to have lower odds of esophagitis (aOR=0.85, 95%CI: 0.84-0.86, p<0.001), esophageal stricture (aOR=0.95, 95%CI: 0.93-0.97, p<0.001), Barrett's esophagus (aOR=0.58, 95%CI: 0.57-0.59, p<0.001) and esophageal cancer (aOR=0.22, 95%CI: 0.21-0.23, p<0.001). CONCLUSIONS: Our study confirms the findings of previous literature that females, despite comprising the majority of the study population, had a lower incidence of GERD related complications. Further studies identifying the underlying reason for these differences are required.

Risk factors associated with functional esophageal disorders (FED) versus gastroesophageal reflux disease (GERD).

INTRODUCTION: Despite the high prevalence of typical symptoms of gastroesophageal reflux disease (GERD), approximately 30% of patients have functional esophageal disorders (FED) on ambulatory reflux monitoring, which may include reflux hypersensitivity (RH; defined as physiologic acid exposure but temporally correlated symptoms of reflux), or functional heartburn (FH; defined as physiologic acid exposure and negative symptom correlation). There are limited epidemiological data characterizing these conditions. We investigated demographic and socioeconomic factors as well as medical comorbidities which may predispose to FED versus pathologic GERD. METHODS: Adult patients with reflux symptoms for at least 3 months were studied with 24-h pH-impedance testing from 11/2019 to 3/2021. Participants were categorized into pathologic GERD, FH, or RH using pH-impedance data and reported symptom correlation. Demographic data, including age, gender, race/ethnicity, zip code, insurance status, and medical comorbidity data were retrospectively retrieved from the electronic medical record on all participants. RESULTS: 229 patients were included. Non-Hispanic Asian ethnicity (OR 5.65; p = 0.01), underweight BMI (OR 7.33; p = 0.06), chronic pain (OR 2.33; p < 0.01), insomnia (OR 2.83; p = 0.06), and allergic rhinitis (OR 3.90; p < 0.01) were associated with a greater risk for FED. Overweight BMI (OR 0.48; p = 0.03) and alcohol use (OR 0.57; p = 0.06) were associated with a decreased risk for FED. DISCUSSION: This is the first report of a greater risk of FED in patients with underweight BMI, insomnia, chronic pain, allergic rhinitis, or of Asian or Hispanic ethnicities. The weak associations between female gender and anxiety are corroborated in other studies. Our findings enable clinicians to better screen patients with reflux for this disorder.

Incidence of Post-operative Gastro-esophageal Reflux Disorder in Patients Undergoing Laparoscopic Sleeve Gastrectomy: A Systematic Review and Meta-analysis.

Gastroesophageal reflux disease (GERD) is a common concern following laparoscopic sleeve gastrectomy (LSG). This paper aimed to assess the incidence of reflux disease following these bariatric procedures. A literature search was conducted to identify observational studies and clinical trials reporting patients developed GERD disease after LSG. Twenty-two studies included in the analysis, involve 20,495 participants, indicated that the estimated proportion of patients who developed post-surgery GERD was 0.35 (95% CI 0.30-0.41). Subgroup analysis revealed a proportion of 0.33 (95% CI 0.27-0.38) in observational studies and 0.58 (95% CI 0.39-0.75) in clinical trials. High heterogeneity was noted across studies (I2 = 98%). Sensitivity analyses and publication bias assessments were performed to enhance the robustness of the results. Our findings highlight a moderate to high risk of developing GERD following LSG surgery.

Extrapulmonary Comorbidities Associated with Chronic Obstructive Pulmonary Disease: A Review.

Most patients with chronic obstructive pulmonary disease (COPD) suffer from at least one additional, clinically relevant chronic disease. To a degree, the high global prevalence and mortality rate of COPD is closely related to its extrapulmonary effects. Moreover, the various of comorbidities of COPD and itself interact with each other, resulting in diverse clinical manifestations and individual differences, and thus further influencing the prognosis as well as healthcare burden of COPD patients. This is closely related to the common risk factors of chronic diseases (aging, smoking, inactivity, etc.). Additionally, some pathophysiological mechanisms caused by COPD, including the systemic inflammatory response, hypoxia, oxidative stress, and others, also have an impact on other systems. But comprehensive management and medical interventions have not yet been established. The clinicians should improve their knowledge and skills in diagnosing as well as treating the comorbidities of COPD, and then aim to develop more individualized, efficient diagnostic and therapeutic strategies for different patients to achieve greater clinical benefits. In this article, we will review the risk factors, mechanisms, and treatment strategies for extrapulmonary comorbidities in chronic obstructive pulmonary disease, including cardiovascular diseases, diabetes, anemia, osteoporosis, emotional disorders, and gastroesophageal reflux disease.

Associations between Proton-Pump Inhibitor Usage, Allergy, and Asthma: An Analysis of NHANES 2005-2006.

INTRODUCTION: Acid suppression medications, such as proton-pump inhibitors (PPIs) and histamine-2 receptor antagonists, are commonly prescribed for the treatment of gastroesophageal reflux disease and other gastrointestinal disorders. However, concerns regarding potential long-term side effects are brought up by the overuse of PPIs. This study aimed to investigate the relationship between PPI usage, allergy, and asthma in the general US population. METHODS: Data of individuals aged ≥20 years who had information on PPI use and questionnaires on allergy and asthma in the US National Health and Nutrition Examination Survey (NHANES) 2005-2006 were analyzed. Univariate and multivariable logistic regression analyses were performed to determine the associations between PPI use, prevalent allergy, and asthma. RESULTS: A total of 4,481 participants (representing 198,543,007 US individuals after weighting) were included in the analyses. PPI use was not significantly associated with the presence of allergy or asthma in the general study population after adjustment. However, in females without steroid exposure, PPI use was significantly associated with increased odds of allergy (adjusted odds ratio [aOR] = 1.69, 95% confidence interval [CI]: 1.002-2.86), among which esomeprazole use was significantly associated with increased odds of allergy (aOR = 2.68, 95% CI: 1.30-5.54) and lansoprazole with increased odds of asthma (aOR = 3.44, 95% CI: 1.50-7.87) as compared to no PPI use. Duration of PPI use was not significantly associated with allergy or asthma. CONCLUSIONS: In US women without steroid exposure, PPI use is associated with increased likelihood of prevalent allergy and asthma.

Surgical Aspects of Sleeve Gastrectomy Are Related to Weight Loss and Gastro-esophageal Reflux Symptoms.

INTRODUCTION: A large variation in outcome has been reported after sleeve gastrectomy (SG) across countries and institutions. We aimed to evaluate the effect of surgical technique on total weight loss (TWL) and gastro-esophageal reflux disease (GERD). METHODS: Observational cohort study based on data from the national registries for bariatric surgery in the Netherlands, Norway, and Sweden. A retrospective analysis of prospectively obtained data from surgeries during 2015-2017 was performed based on 2-year follow-up. GERD was defined as continuous use of acid-reducing medication. The relationship between TWL, de novo GERD and operation technical variables were analyzed with regression methods. RESULTS: A total of 5927 patients were included. The average TWL was 25.6% in Sweden, 28.6% in the Netherlands, and 30.6% in Norway (p < 0.001 pairwise). Bougie size, distance from the resection line to the pylorus and the angle of His differed between hospitals. A minimized sleeve increased the expected total weight loss by 5-10 percentage points. Reducing the distance to the angle of His from 3 to just above 0 cm increased the risk of de novo GERD five-fold (from 3.5 to 17.8%). CONCLUSION: Smaller bougie size, a shorter distance to pylorus and to the angle of His were all associated with greater weight loss, whereas a shorter distance to angle of His was associated with more de novo reflux.
