Abstract
Background In 2023, the diagnostic criteria for gastroesophageal reflux disease (GERD) were updated in the Lyon Consensus 2.0. It is important to investigate the diagnostic accuracy of complementary tests used for GERD diagnosis. Objectives To determine the diagnostic accuracy of mean nocturnal basal impedance (MNBI) measured by pH-metry in patients with suspected GERD compared to the updated 2023 Lyon Consensus Diagnostic Criteria and to identify the optimal cutoff point for diagnosis. Design Diagnostic test study based on a retrospective cohort of patients with suspected GERD. Methods Diagnosis was confirmed using the updated Lyon criteria as the gold standard. We evaluated sensitivity, specificity, and discriminatory ability via area under the receiver operating characteristic curve (AUC-ROC). The best cutoff point was determined using Liu's method for MNBI, number of reflux episodes, number of acid reflux episodes, DeMeester score, and bolus exposure time. ROC curves were compared using DeLong's method. Results A total of 55 patients were included, with 26 diagnosed positive and 29 negative for GERD. MNBI yielded an AUC-ROC of 0.77 (95% confidence interval (CI): 0.64-0.89); at 1590 ohms, sensitivity and specificity were 69.2% and 72.4%, respectively. The DeMeester score demonstrated superior discriminatory ability over MNBI (p = 0.03), with an AUC-ROC of 0.90 (95% CI: 0.80-1.00), sensitivity of 92%, and specificity of 93% at a cutoff of 15.6. No significant differences in discriminatory ability were observed when comparing MNBI with other complementary tests (p < 0.05). Conclusion MNBI and other complementary tests showed suboptimal characteristics for GERD diagnosis. These tests should be interpreted alongside clinical, endoscopic, and pH-metry findings. The DeMeester score seems promising, but further prospective studies are needed to prove its utility.

Sleep disorders and hyperarousal among patients with endometriosis: A case-control survey study. Eur J Obstet Gynecol Reprod Biol 2024; 300:287-295.

Abstract
BACKGROUND Endometriosis has been associated with sleep disorders, and hyperarousal appears to be involved in their pathogenesis; however, the presence of hyperarousal in the endometriosis population was never investigated. METHODS We conducted a case-control survey study by sending a questionnaire to all endometriosis patients followed up at our Centers. Controls were recruited among the general population. The questionnaire included demographic information, symptoms and history of endometriosis, the Hyperarousal Scale (H-Scale), the Pittsburgh Sleep Quality Index (PSQI), and the Insomnia Severity Index (ISI). RESULTS A total of 847 women completed the questionnaires: 430 (50.8 %) had endometriosis, and 417 (49.2 %) were controls. Endometriosis was associated with higher H-scale score (OR 2.9, 95 % CI 2.4-3.8, p = 0.000), higher PSQI score (OR 4.3, 95 % CI 3.2-5.7, p = 0.000), and higher ISI score (OR 4.6, 95 % CI 3.5-6.1, p = 0.000) in multivariable ordinal logistic regressions analysis. With path analysis, hyperarousal (H-Scale) reported a partial mediating role in the association between endometriosis and sleep disorders. The mediation effect represented 22.3-27.8 % of the entire association between endometriosis and sleep disturbances. CONCLUSION Endometriosis patients complaining sleep disorders may benefit by investigating the presence of hyperarousal given cognitive behavioral therapy was reported effective in improving hyperarousal and associated sleep disorders.

Abstract
OBJECTIVES The association between obesity and gastroesophageal reflux disease (GERD) is well-established in adults; however, data in pediatric population is scarce. Our study aimed to assess the association between GERD and health-related quality of life (HRQoL) in overweight children. METHODS From April to August of 2020, we included children aged 7-18 years who attended the Endocrinological Outpatient Clinic at the Paediatric Institute, University of Debrecen, Hungary. The participants completed two questionnaires: the Pediatric Gastroesophageal Reflux Disease Symptom Questionnaire (PGSQ) and the HRQoL questionnaire (PedsQL). Based on the criteria of the World Health Organization (WHO), the patients were categorized into two groups: an overweight or obese group and a group with normal weight. RESULTS A total of 107 children (51 % female, mean age 13.2 years, 46 % overweight or obese) completed the questionnaires. The median PGSQ score was similar in both groups (4.0 (IQR: 1.0-7.8) vs. 3.0 (IQR: 1.0-7.0), p=0.6). However, the total PedsQL score was significantly lower in the children with overweight or obesity compared to those with normal weight (80.1 (71.1-91.0) vs. 88.0 (76.1-94.6), p=0.031). The PedsQL score was lower among overweight patients with GERD symptoms than that of normal-weight patients without GERD symptoms. CONCLUSIONS Our findings highlight the importance of raising awareness about GERD to enhance the HRQoL and prevent long-term complications in obese children.

Abstract
Overweight and obesity are a public health problem and in 1997 obesity was recognized as a global epidemic by the World Health Organization (WHO). Overweight and obesity affect almost 60% of adults and one in three children in Europe according to the most recent WHO report. Objectively, gastroesophageal reflux disease (GERD) is defined as the presence of characteristic esophageal mucosal damage assessed by endoscopy and/or the demonstra-tion of pathological acid exposure by reflux monitoring studies. The prevalence of GERD is increased in obese patients In overweight and obese patients, the clinical symptoms of GERD are especially present in the supine position and this correlates with more frequent episodes of nocturnal reflux in the 24-h pH monitoring, there is also an increase in the number of refluxes with content acid. In the population with symptoms, digestive endoscopy detects data of erosive esophagitis in 50% of patients, while 24-h pH-impedanciometry diagnoses 92% of patients with non-erosive reflux disease (NERD) The presence of persistent GERD in the mucosa affects esophageal motility and patients may develop ineffective esophageal motility-type disorders, so we will review the interpre-tation of the functional tests that determine motility, which is esophageal manometry, and those that determine reflux gastroesophageal, acid and non-acid, which is the pH measure-ment with or without 24-h impedanciometry.

Abstract
INTRODUCTION An increased transdiaphragmatic pressure gradient (TGP) is a main element for distal gastroesophageal reflux disease (GERD). The role of TGP for proximal reflux is still unclear. This study aims to evaluate the presence, severity, and importance of proximal reflux in relationship to the TGP, comparing healthy volunteers, obese individuals, and patients with chronic obstructive pulmonary disease (COPD). METHODS We studied 114 individuals comprising 19 healthy lean volunteers, 47 obese individuals (mean body mass index 45 ± 7 kg/m2), and 48 patients with COPD. All patients underwent high-resolution manometry and dual-channel esophageal pH monitoring. Esophageal motility, thoracic pressure (TP), abdominal pressure (AP), TGP, DeMeester score, and % of proximal acid exposure time (pAET) were recorded. RESULTS Pathologic distal GERD was found in 0, 44, and 57% of the volunteers, obese, and COPD groups, respectively. pAET was similar among groups, only higher for obese individuals GERD + as compared to obese individuals GERD - and COPD GERD -. pAET did not correlate with any parameter in healthy individuals, but it correlated with AP in the obese, TP in the COPD individuals, and TGP and DeMeester score in both groups. When all individuals were analyzed as a total, pAET correlated with AP, TGP, and DeMeester score. DeMeester score was the only independent variable that correlated with pAET. CONCLUSIONS Our results show that (a) TGP is an important mechanism associated with distal esophageal acid exposure and this fact is linked with proximal acid exposure and (b) obesity and COPD both seem to be primary causes for GERD but not directly for proximal reflux.

Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is common in patients with obesity. Diagnosing GERD is important as bariatric operations have different influence on GERD. We assessed reflux symptoms and objective findings prior to surgery. METHODS Work-up included esophageal symptoms quantification by VAS-scores, esophagogastroduodenoscopy (EGD) and 24-h impedance-pH (imp-pH) monitoring off PPI therapy. Imp-pH was classified as abnormal if either %time pH<4 was abnormal, total number of reflux episodes was elevated or symptom index (SI) was positive. RESULTS Among 100 consecutive patients (68F, age 40±11years, BMI 44.9±6.9kg/m2) 54% reported heartburn and/or regurgitation, 71% had objective evidence of GERD (38% endoscopic lesions and 33% only abnormal imp-pH results). Imp-pH was superior to EGD in identifying GERD (sensitivity 85% vs. 54%, p<0.01). Symptomatic and asymptomatic patients had similar prevalence of esophageal lesions (37% vs. 39%) and abnormal imp-pH findings (68% vs. 50%). Sixty nine percent of patients with abnormal %time pH<4 had a normal number of reflux episodes. CONCLUSION Half of patients with obesity reported typical GERD symptoms and >70% had evidence of GERD. Poor acid clearance was the main mechanisms. Since typical reflux symptoms don't predict objective findings, endoscopy and reflux monitoring should be part of the surgery work-up especially before restrictive procedures.

Abstract
PURPOSE This study was performed to evaluate the quality of sleep in snoring obese children without obstructive sleep apnea (OSA); and to study the possible relationship between sleep interruption and gastroesophageal reflux (GER) in snoring obese children. METHODS Study subjects included 13 snoring obese children who were referred to our sleep lab for possible sleep-disordered breathing. Patients underwent multichannel intraluminal impedance and esophageal pH monitoring with simultaneous polysomnography. Exclusion criteria included history of fundoplication, cystic fibrosis, and infants under the age of 2 years. Significant association between arousals and awakenings with previous reflux were defined by symptom-association probability using 2-minute intervals. RESULTS Sleep efficiency ranged from 67-97% (median 81%). A total of 111 reflux episodes (90% acidic) were detected during sleep, but there were more episodes per hour during awake periods after sleep onset than during sleep (median 2.3 vs. 0.6, p=0.04). There were 279 total awakenings during the sleep study; 56 (20.1%) of them in 9 patients (69.2%) were preceded by reflux episodes (55 acid, 1 non-acid). In 5 patients (38.5%), awakenings were significantly associated with reflux. CONCLUSION The data suggest that acid GER causes sleep interruptions in obese children who have symptoms of snoring or restless sleep and without evidence of OSA.

Abstract
AIM To investigate the relationship between reflux and body mass index (BMI) in the asymptomatic obese population using the impedance-pH technique. METHODS Gastroesophageal reflux is frequent in the obese population. However, the relationship between acid reflux and BMI in asymptomatic obese people is unclear. Forty-six obese (BMI > 25 kg/m(2)) people were enrolled in this prospective study. We evaluated the demographic findings and 24-h impedance pH values of the whole group. Gas, acid (pH < 4), weak acid (pH = 4-7) and weak alkaline (pH ≥ 7) reflux parameters were analyzed. RESULTS The mean age of patients was 49.47 ± 12.24 years, and half of them were men. The mean BMI was 30.64 ± 3.95 kg/m(2) (25.14-45.58 kg/m(2)). BMI of 23 was over 30 kg/m(2). Seventeen patients had a comorbidity (hypertension, diabetes mellitus, or ischemic heart disease). Endoscopic examination revealed esophagitis in 13 of the 28 subjects (10 Grade A, 3 Grade B). The subjects were divided into two groups according to BMI (< 30 and > 30 kg/m(2)). Demographic and endoscopic findings, and impedance results were similar in these two groups. However, there was a positive correlation between BMI and total and supine pH < 4 episodes (P = 0.002, r = 0.414; P = 0.000, r = 0.542), pH < 4 reflux time (P = 0.015, r = 0.319; P = 0.003, r = 0.403), and DeMeester score (P = 0.012, r = 0.333). CONCLUSION Acid reflux is correlated with BMI in asymptomatic obese individuals.
