Current Medicinal Chemistry Jun 2024This study aimed to explore the potential causal relationship between dietary habits and Gastroesophageal Reflux Disease (GERD).
PURPOSE
This study aimed to explore the potential causal relationship between dietary habits and Gastroesophageal Reflux Disease (GERD).
METHODS
Using the inverse-variance weighted method, a two-sample Mendelian randomization (MR) analysis was performed to investigate the causal relationship between 22 dietary habits and GERD. The stability and reliability of the results were assessed using leave-one-out analysis, heterogeneity tests, and tests for horizontal pleiotropy based on the effect measure odds ratio (OR) and 95% confidence interval (CI).
RESULTS
The results of the MR analysis indicated a positive association between alcohol drinking (OR=1.472; 95% CI, 1.331 to 1.629; p<1.0×10-3) and salt added to food (OR=1.270; 95% CI, 1.117 to 1.443; p<1.0×10-3) with the risk of GERD. Conversely, bread intake (OR=0.613; 95% CI, 0.477 to 0.790; p<1.0×10-3), cereal intake (OR=0.613; 95% CI, 0.391 to 0.677; p<1.0×10-3), cheese intake (OR=0.709; 95% CI, 0.593 to 0.846; p<1.0×10-3), dried fruit intake (OR=0.535; 95% CI, 0.404 to 0.709; p<1.0×10-3), fresh fruit intake (OR=0.415; 95% CI, 0.278 to 0.619; p<1.0×10-3), and oily fish intake (OR=0.746; 95% CI, 0.633 to 0.879; p<1.0×10-3) were negatively associated with the risk of GERD. Sensitivity analysis showed no evidence of reverse causation, pleiotropy, or heterogeneity.
CONCLUSION
Alcohol and salt added to food raised GERD risk, while bread intake, cereal intake, cheese intake, intake of certain dried fruits and certain fresh fruits, and oily fish lowered it. Our study affirms the potential causal link between these diets and GERD, offering insights into targeted prevention strategies.

Stimulants are the first-line pharmacological treatment for attention deficit hyperactivity disorder (ADHD). We present the unique case of a patient who developed a chewing compulsion when taking mixed amphetamine salts (MAS). A 32-year-old female patient with a past medical history of gastroesophageal reflux disease (GERD), gastroparesis, and migraines was seen for initial psychiatric assessment due to concerns for irritability. She was diagnosed with post-traumatic stress disorder (PTSD); generalized anxiety disorder; ADHD, inattentive type; and unspecified bipolar disorder. Lamotrigine was started and titrated to 25mg twice per day, with improved mood stability. MAS immediate-release (IR) was started at 2.5mg and titrated to 5mg daily for ADHD. She then experienced an uncontrollable urge to chew, finding relief when chewing on a child's teething necklace, which provided satisfaction and a reduction in anxiety. She denied jaw tightness or teeth grinding. The dose of MAS IR was reduced to 2.5mg daily with improvement in symptoms and later increased again to 5mg daily, which she was then able to tolerate. Stereotyped biting behaviors have been observed in rats with the use of amphetamines, and the onset of compulsive behavior has emerged in children with the use of dextroamphetamine. However, this is the first known case of compulsive chewing or biting movements reported in humans with MAS use. This case highlights the need to assess patients for adverse events, such as compulsive biting and chewing movements or other oral facial stereotypies, after commencement of stimulants, including MAS.

Meta-Analysis
BACKGROUND
Observational studies have preliminarily revealed an association between smoking and gastroesophageal reflux disease (GERD). However, little is known about the causal relationship and shared genetic architecture between the two. This study aims to explore their common genetic correlations by leveraging genome-wide association studies (GWAS) of smoking behavior-specifically, smoking initiation (SI), never smoking (NS), ever smoking (ES), cigarettes smoked per day (CPD), age of smoking initiation(ASI) and GERD.
METHODS
Firstly, we conducted global cross-trait genetic correlation analysis and heritability estimation from summary statistics (HESS) to explore the genetic correlation between smoking behavior and GERD. Then, a joint cross-trait meta-analysis was performed to identify shared "pleiotropic SNPs" between smoking behavior and GERD, followed by co-localization analysis. Additionally, multi-marker analyses using annotation (MAGMA) were employed to explore the degree of enrichment of single nucleotide polymorphism (SNP) heritability in specific tissues, and summary data-based Mendelian randomization (SMR) was further utilized to investigate potential functional genes. Finally, Mendelian randomization (MR) analysis was conducted to explore the causal relationship between the smoking behavior and GERD.
RESULTS
Consistent genetic correlations were observed through global and local genetic correlation analyses, wherein SI, ES, and CPD showed significantly positive genetic correlations with GERD, while NS and ASI showed significantly negative correlations. HESS analysis also identified multiple significantly associated loci between them. Furthermore, three novel "pleiotropic SNPs" (rs4382592, rs200968, rs1510719) were identified through cross-trait meta-analysis and co-localization analysis to exist between SI, NS, ES, ASI, and GERD, mapping the genes MED27, HIST1H2BO, MAML3 as new pleiotropic genes between SI, NS, ES, ASI, and GERD. Moreover, both smoking behavior and GERD were found to be co-enriched in multiple brain tissues, with GMPPB, RNF123, and RBM6 identified as potential functional genes co-enriched in Cerebellar Hemisphere, Cerebellum, Cortex/Nucleus accumbens in SI and GERD, and SUOX identified in Caudate nucleus, Cerebellum, Cortex in NS and GERD. Lastly, consistent causal relationships were found through MR analysis, indicating that SI, ES, and CPD increase the risk of GERD, while NS and higher ASI decrease the risk.
CONCLUSION
We identified genetic loci associated with smoking behavior and GERD, as well as brain tissue sites of shared enrichment, prioritizing three new pleiotropic genes and four new functional genes. Finally, the causal relationship between smoking behavior and GERD was demonstrated, providing insights for early prevention strategies for GERD.

Surgical Endoscopy Jun 2024To explore the feasibility of peroral endoscopic myotomy (POEM) in patients with achalasia and hiatal hernia.
PURPOSE
To explore the feasibility of peroral endoscopic myotomy (POEM) in patients with achalasia and hiatal hernia.
MATERIALS AND METHODS
We performed a retrospective review of 2136 patients with achalasia between January 2016 and December 2022. Patients with achalasia and hiatal hernia were assigned into study group, and matched patients with achalasia but no hiatal hernia were assigned into control group. The preoperative baseline information, procedure-related adverse events (AEs) and follow-up data were compared between the two groups.
RESULTS
Hiatal hernia was identified in 56/1564 (3.6%) patients with achalasia. All of these patients underwent POEM with success. The preoperative baseline characteristics were similar between the study and control group. The study group presented with a similar rate of mucosal injury (12.5% vs 16.1, P = 0.589), pneumothorax (3.6% vs 1.8%, P = 1.000), pleural effusion (8.9% vs 12.5%, P = 0.541) and major AEs (1.8% vs 1.8%, P = 1.000) compared with the control group. As for the follow-up data, no significant differences were observed in clinical success (96.4% vs 92.9%, P = 0.679; 93.6% vs 94.0%, P = 1.000; 86.5% vs 91.4%, P = 0.711) clinical reflux (25.0% vs 19.6%, P = 0.496; 31.9% vs 26.0%, P = 0.521; 35.1% vs 31.4%, P = 0.739) and proton pump inhibitor usage (17.9% vs 16.1%, P = 0.801; 29.8% vs 24.0%, P = 0.520; 32.4% vs 25.7%, P = 0.531) between the study group and control group at 1-year, 2-year and 3-year follow-ups.
CONCLUSIONS
POEM is a safe and effective treatment for achalasia combined with hiatal hernia.

To evaluate the safety and efficacy of domestically produced magnetic sphincter augmentation (MSA) for gastroesophageal reflux disease. This study is a prospective cohort study. Patients with typical heartburn and reflux symptoms (at least partial response to proton pump inhibitors), abnormal esophageal acid exposure and normal esophageal peristalsis were included, prospectively in the Department of Gastroesophageal Surgery, Rocket Force Characteristic Medical Center from June 2019 to September 2022. Patients with hiatal hernia >2 cm and severe esophagitis were excluded. The MSA was wrapped around the distal esophagus after esophageal hiatus repair by laparoscopy. A postoperative questionnaire survey was conducted to assess the relief of symptom, complications, the discontinuation rate of proton pump inhibitor, and surgical satisfaction. Gastroscopy, high-resolution esophageal pressure measurement, and pH value impedance monitoring were also reviewed. Currently, 23 patients with gastroesophageal reflux disease were enrolled and underwent MSA surgery. There were 20 males and 3 females, aged ( (IQR)) 48 (14) years (range: 25 to 64 years). All cases were successfully implanted with MSA. Subjective indicators were followed for 17 (18) months (range: 14 to 53 months), while objective indicators were followed for 17 (1) months (range: 12 to 23 months). The postoperative gastrointestinal and extraesophageal symptom scores showed a significant decrease compared to preoperative levels as follows: the degree of subjective relief of overall digestive symptoms was 90 (20)% (range:0~100%), the degree of subjective relief of overall respiratory symptoms was 100(10)% (range: 10%~100%), the overall satisfaction rate was 83% (19/23), the proton pump inhibitor discontinuation rate was 70% (16/23). The proportion of esophagitis has decreased from 44% (10/23) to 9% (2/23) (κ=0.169, =0.039), The Hill grade of gastroesophageal valve morphology improved from 1 case of grade Ⅰ, 5 cases of grade Ⅱ, 10 cases of grade Ⅲ, and 7 cases of grade Ⅲ preoperative to 22, 1, 0, and 0 cases postoperative. The proportion of lower esophageal sphincter pressure below normal has decreased from 70% (16/23) to 35% (8/23) (κ=0.170, =0.012). There were 21 patients who restored normal esophageal acid exposure. Eleven patients had mild long-term dysphagia, but it didn't affect their daily life. No postoperative device migration, erosion, or secondary surgical removal occurred. Laparoscopic implantation of the MSA device was safe and well tolerated. It can effectively control the symptoms of gastroesophageal reflux disease, reduce medication, restore normal cardia morphology and function, and esophageal acid exposure. The main postoperative complication was dysphagia, but it was relatively mild.

Modified One Anastomosis Gastric Bypass Following Sleeve Gastrectomy for Severe Reflux and Delayed Gastric Emptying: A Prospective Trial with Clinical and Physiological Outcome Measures.
BACKGROUND
Gastro-esophageal reflux (GORD) following sleeve gastrectomy (SG) is a central challenge, and precise indications for revisional surgery or the physiology have not been precisely defined. We aimed to determine whether OAGB performed for reflux post-SG (1) accelerates gastric emptying half-time, (2) reduces the frequency and severity of reflux events, and (3) improves reflux symptoms.
METHODS
We undertook a prospective trial (ACTRN12616001089426). There were 22 participants who underwent measurement before and after revisional surgery with 29 optimal SG (patients with optimal outcome from their primary surgery) as controls. All participants underwent a protocolized nuclear scintigraphy, 24-h pH monitoring, and gastroscopy and completed objective questionnaires.
RESULTS
Trial patients were 90.9% female, age 44.4 years. Conversion from SG to OAGB was at a median of 45.2 ± 19.6 months. Scintigraphy showed an increased rate of gastric emptying post-OAGB 34 (IQR 14) vs 24 (IQR 10.3) min, p-value 0.008, with decreased number of reflux events post-prandially (39 (IQR 13) vs 26 (IQR 7), p-value 0.001). This data correlated with the pH analysis; total acid events substantially reduced post-OAGB 58.5 (IQR 88) vs 12 (IQR 9.4) events, p-value 0.017. Endoscopic findings indicated a reduction in incidence of bile stasis 72.7% vs 40.9% post-OAGB, p-value < 0.00010. Post-OAGB, patients experienced less frequent regurgitation (12 ± 4.1 vs. 5.5 ± 3, p-value 0.012) and reflux (37.1 ± 15.7 vs. 16.8 ± 12.6, p-value 0.003).
CONCLUSIONS
We found OAGB is an effective treatment for reflux associated with delayed gastric emptying post-SG. The likely mechanisms is by, an increase in the rate of gastric clearance and reduced reflux events and overall esophageal acid exposure. This suggests that some forms of post-SG reflux are driven by slower emptying of the residual stomach and are amenable to treatment with drainage above the incisura.

Background Gastroesophageal reflux disease (GERD) is a global gastrointestinal disorder, and obesity is a particular risk factor. Symptoms of GERD, such as heartburn and acid reflux, are caused by abnormal relaxation in the lower esophagus, causing gastric acid reflux. Persistent symptoms can affect the patient's quality of life (QOL) and can cause complications, such as esophageal adenocarcinoma. Management of GERD includes lifestyle changes, antacids, and anti-reflux surgery. Even though GERD is a common disease, few research has been carried out on it in Saudi Arabia. Aim This study aimed to estimate the prevalence of GERD and its associated risk factors among obese individuals in the Al-Baha region population and the effect of GERD on their QOL. Methods A cross-sectional study included 314 obese participants from the Al-Baha region. A questionnaire was filled out to measure the prevalence of GERD, risk factors, and effects on the QOL of the participants. Data were analyzed by the IBM SPSS Statistics for Windows, version 26.0 (released 2019, IBM Corp., Armonk, NY). Descriptive statistics and the chi-squared test were applied. Logistic regression analysis was used to determine the factors associated with the incidence of GERD. A -value of <0.05 was considered statistically significant. Results A total of 314 patients who met our inclusion criteria completed the survey; 42% of them were women, the mean age of all patients was 35.3 ± 12.9 years, and 38.2% of the patients were diagnosed with GERD. Epigastric pain and burning sensation were the most common symptoms (44.9%). Five out of six domains in the QOL questionnaire showed more effects among GERD participants than non-GERD participants, and the results were statistically significant ( = 0.001). Logistic regression analysis showed that men are 1.8 times more likely than women to be diagnosed with GERD, and smokers have 2.6 times the risk of being diagnosed with GERD than non-smokers. Conclusion The present study showed a high prevalence of GERD among obese patients in the Al-Baha region, negatively affecting their QOL. Major risk factors included gender, smoking, dyslipidemia, and hypertension. Public health programs to raise awareness of these risk factors and lifestyle habits are necessary to improve QOL and prevent complications.

Gastric acid secretion is closely associated with the development and treatment of chronic gastritis, gastric ulcers, and reflux esophagitis. However, gastric acid secretion is affected by complex physiological and pathological factors, and real-time detection and control are complicated and expensive. A gastric delivery system for antacids and therapeutics in response to low pH in the stomach holds promise for smart and personalized treatment of stomach diseases. In this study, pH-responsive modular units were used to assemble various modular devices for self-regulation of pH and drug delivery to the stomach. The modular unit with a release window of 50 mm could respond to pH and self-regulate within 10 min, which is related to its downward floatation and internal gas production. The assembled devices could stably float downward in the medium and detach sequentially at specific times. The assembled devices loaded with antacids exhibited smart pH self-regulation under complex physiological and pathological conditions. In addition, the assembled devices loaded with antacids and acid suppressors could multi-pulse or prolong drug release after rapid neutralization of gastric acid. Compared with traditional coating technology, 3D printing can print the shell layer by layer, flexibly adjust the internal and external structure and composition, and assemble it into a multi-level drug release system. Compared with traditional coating, 3D-printed shells have the advantage of the flexible adjustment of internal and external structure and composition, and are easy to assemble into a complex drug delivery system. This provides a universal and flexible strategy for the personalized treatment of diseases with abnormal gastric acid secretion, especially for delivering acid-unstable drugs.

BACKGROUND
Patients with chronic laryngopharyngeal symptoms, with or without pathologic reflux, frequently have poor response to standard therapies, which may be a result of overlapping cognitive-affective processes. Therefore, the aims of this study included measuring psychosocial distress and laryngeal-specific cognitive distress in patients with chronic laryngopharyngeal symptoms (LPS) as well as comparing these among laryngeal symptomatic patients with and without conclusive gastroesophageal reflux disease (GERD).
METHODS
This prospective, single-center study enrolled adults with chronic LPS from 9/22 to 6/23. Patients completed eight questionnaires on quality of life, symptom burden, and psychosocial distress. The laryngeal cognitive affective tool (LCAT) assessed laryngeal-specific hypervigilance and anxiety; LCAT scores ≥33 were elevated. All patients underwent objective testing with endoscopy and/or ambulatory reflux monitoring and were categorized as proven GERD (GER+) or no proven GERD (GER-).
KEY RESULTS
One hundred twenty-nine patients were included: 66% female, mean age 54.1 (17.5) years, mean BMI 27.6 (6.8) kg/m, 66% Caucasian, 57% with an elevated LCAT, and 53% GER+. Moderate-to-severe anxiety was found in 39% and moderate-to-severe depression in 19%. An elevated LCAT alone or with an elevated anxiety/depression score was found in 58%. Patient-reported outcomes scores, including LCAT scores (32.9 (13.8) GER- vs. 33.1 (12.6) GER+, p = 0.91), were similar between patients with and without GER+.
CONCLUSIONS AND INFERENCES
Patients with chronic LPS experience heightened levels of hypervigilance, symptom-specific anxiety, and psychosocial distress, regardless of the presence of pathologic GER.
