Gastroesophageal reflux disease: Important considerations for the older patients

Evaluation of the Susceptibility of Bangladeshi University Students to Gastroesophageal Reflux Disease (GERD) and Its Associated Factors: A Cross-Sectional Study

Background and Aims

Gastroesophageal reflux disease (GERD) is a highly prevalent clinical condition all over the world. The study was conducted to determine the GERD prevalence among Bangladeshi university students using the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) score and to find out what factors are linked to the disease.

Methods

The study was based on descriptive cross-sectional analysis. After a comprehensive literature review, a questionnaire was developed with some pre-structured options kept in the sociodemographic, dietary, and lifestyle sections along with the FSSG parameters. The tool was disseminated among students of different universities in Bangladesh. After receiving the responses, all the data was analyzed using SPSS software (version 26.0).

Results

After scrutiny, 402 responses of the study participants were subjected to statistical analysis, and among participants, 57.2% (N = 230) were female and 42.8% (N = 172) were male. The GERD prevalence was 45.5% (N = 183), which indicated the FSSG score was more than 8 among 45.5% of the individuals. Logistic regression analysis revealed that eating beyond fullness (OR = 2.859, CI = 1.811-4.515), consumption of painkillers (OR = 2.237, CI = 1.370-3.653), anxiety (OR = 2.349, CI = 1.529-3.611), being stressed (OR = 2.255, CI = 1.456-3.494), quick eating habit (OR = 1.845, CI = 1.240-2.745), poor sleep quality (OR = 1.760, CI = 1.183-2.620), fast food consumption (OR = 1.613, CI = 1.082-2.404), eating sour and spicy food regularly (OR = 1.610, CI = 1.073-2.415), female gender (OR = 1.595, CI = 1.068-2.381), less interval between dinner and sleep (OR = 1.561, CI = 1.020-2.389), being alone most of the time (OR = 1.514, CI = 1.016-2.257), were significantly associated with the occurrence of GERD symptoms.

Conclusion

GERD symptoms were seen among a large number of university students. Various sociodemographic, dietary, and lifestyle-related factors had an impact on the disease; these contributing factors should be positively modified to alleviate the burden of GERD symptoms.

Serum potassium levels as an independent predictor of unplanned enteral nutrition discontinuation in older adults with gastroesophageal reflux disease

BACKGROUND & AIMS

Enteral nutrition in older adults is often associated with intolerance, a phenomenon not well-understood in the context of gastroesophageal reflux disease (GERD). This observational study aimed to evaluate serum potassium levels as an independent prognostic factor for unplanned enteral nutrition discontinuation in older adults with GERD.

METHODS

We conducted a retrospective analysis of 213 consecutive patients with GERD who received enteral nutrition at our institution from April 2018 to March 2023. The dietary assessment involved extracting relevant nutritional information from the patients' medical records. The incidence of enteral nutrition discontinuation due to complications was monitored over a 30-day period after initiation.

RESULTS

Patients were categorized into three groups based on initial serum potassium levels: low (<4.0 mmol/L), intermediate (4.0-4.5 mmol/L), and high (≥4.5 mmol/L). During the follow-up, 35 % of patients experienced events leading to the discontinuation of enteral nutrition. Higher potassium levels correlated with an increased risk of unplanned discontinuation of enteral nutrition (log-rank P = 0.002). Multivariate Cox proportional hazards analysis identified serum potassium level as an independent predictor of unplanned discontinuation (hazard ratio: 1.700 [95 % confidence interval: 1.100-2.627] per 1 mmol/L, P = 0.017).

CONCLUSIONS

Serum potassium level is a robust independent predictor of unplanned enteral nutrition discontinuation in older adults with GERD. Our findings suggest that monitoring and adjusting potassium levels may be essential for improving outcomes in this vulnerable population.

Understanding the demographic and socioeconomic determinants of morbidity in Eastern Uganda: a retrospective analysis of the Iganga-Mayuge health and demographic surveillance data

Introduction

Understanding the determinants of disease burden is imperative in enhancing population health outcomes. This study uses data from the Iganga-Mayuge Health and Demographic Surveillance Site, to understand demographic and socioeconomic factors influencing morbidity.

Methods

We analysed secondary data from 2018 to 2023. We employed graphs and tables to present morbidity patterns across different sociodemographic factors and applied mixed-effects multinomial multivariate logistic regression model to understand the correlates of morbidity.

Results

The findings reveal a predominant prevalence of malaria, lower respiratory tract infections, coryza, gastric acid-related and urinary tract infections, collectively constituting 83% of diagnosed diseases. Noteworthy demographic variations, particularly gender and age, significantly impact disease distribution, revealing higher diagnosis rates among females. Additionally, socioeconomic factors, including education and wealth status, contribute to discernible differences in disease burden.

Conclusion

This research provides crucial insights into the implications of demographic and socioeconomic factors on disease burden in Uganda. The results contribute to evidence-based policy-making, highlighting the necessity for targeted interventions addressing specific health challenges encountered by diverse populations. The study advocates for continuous assessment of the epidemiological landscape to inform more tailored and effective health strategies, ultimately enhancing resilience in disease control efforts.

Impact of different gastric acid suppressants on chronic unpredictable mild stress-induced cognitive impairment in rats: A possible involvement of gut dysbiosis

Recently, clinical evidence indicates that gastric acid suppressants are associated with an increased risk of the development of cognitive impairment and dementia, especially in elderly patients and those with mild cognitive impairment. Therefore, the aim of this research was to explore the impact of different gastric acid suppressants use, famotidine (Famo), esomeprazole (Esome) and vonoprazan (Vono) in the absence or the presence of chronic unpredictable mild stress (CUMS) on several memory tasks with examination of the role of gut dysbiosis. In the present study, rats received famotidine (3.7 mg/kg/day, p.o.) or esomeprazole (3.7 mg/kg/day, p.o.) or vonoprazan (1.85 mg/kg/day, p.o.) for 7 weeks with or without exposure to CUMS. Remarkably, CUMS with different acid suppressants caused a significant decrease in all memory tasks in late CUMS in the current investigation. CUMS with acid suppressants also revealed a marked alteration in the fecal Firmicutes/Bacteroidetes ratio compared to CUMS alone. This gut microbiome alteration was associated with an alteration in gut membrane integrity, as revealed by colonic histopathology and an elevation of systemic inflammatory markers. Besides, upregulation of hippocampal amyloid β and p-tau proteins and modification of brain histopathology were noticed. Our findings support the detrimental effect of gastric acid suppressants, especially proton pump inhibitors, on cognitive impairment in the presence of stress, with the possible involvement of gut dysbiosis.

Pembrolizumab in combination with trastuzumab for treatment of HER2-positive advanced gastric or gastro-esophageal junction cancer

Introduction

Gastric cancer remains a challenging malignancy with a high global mortality rate. Recent advances in targeted therapy and immunotherapy have shown promise in improving patient outcomes. This paper reviews the impact of incorporating targeted agents such as trastuzumab and immunotherapeutic agents like pembrolizumab into standard chemotherapy regimens for gastric cancer treatment.

Methods

A comprehensive analysis was conducted on pivotal clinical trials, including KEYNOTE-590, KEYNOTE-811, and ToGA, focusing on their methodologies, patient populations, treatment regimens, and outcome measures. The review also explored emerging research avenues in precision medicine, particularly genomic sequencing and biomarker identification.

Aim

To assess the efficacy and survival benefits of adding trastuzumab and pembrolizumab to standard chemotherapy in the treatment of gastric cancer and to outline future directions in gastric cancer research.

Results

Including trastuzumab and pembrolizumab in treatment regimens for human epidermal growth factor receptor 2 (HER2)-positive and PD-L1-expressing gastric cancers significantly improved progression-free and overall survival rates compared to chemotherapy alone. These findings highlight the potential of personalized therapy in enhancing treatment outcomes. Furthermore, ongoing research into the gastric cancer microenvironment and the role of the microbiome suggests novel targets for future therapeutic interventions.

Conclusion

The integration of targeted and immunotherapeutic agents with traditional chemotherapy represents a pivotal shift in gastric cancer treatment, moving towards more personalized and effective regimens.

Prevalence and risk factors of gastroesophageal reflux disease in Iran: A cross-sectional analysis from the PERSIAN cohort

BACKGROUND

This study assessed the prevalence of gastroesophageal reflux disease (GERD) in a general adult population in Iran. The association between GERD and various factors was also evaluated.

METHODS

We performed a cross-sectional study on 163,018 individuals aged over 35 who were enrolled in the PERSIAN cohort. GERD was defined as the occurrence of heartburn and/or regurgitation symptoms at least several days a month. Survey design analysis for pooled data was performed and multiple regression analysis was conducted to determine the independent risk factors for GERD.

RESULTS

The prevalence of GERD in our study was estimated at 21.86% (95% confidence interval:17.4%-36.4%). The mean age of the participants was 49.84 years±9.25 (35-70) and 44.75% of the participants were male. Symptoms of heartburn and regurgitation were reported in 18.65% (n: 29,170) and 6.06% (n: 9,717) of participants, respectively. In the multivariate analysis, several factors were found to be associated with a higher prevalence of GERD: female sex, age >50, current smoking, opium use, weekly consumption of fried foods, frequent consumption of hot tea, less than 6 hours of sleep per night, psychiatric disorders, usage of NSAIDs, and poor oral hygiene, were associated with a higher prevalence of GERD. Conversely, higher education levels and average physical activity were found to be less commonly associated with GERD.

CONCLUSION

We found a relatively high prevalence of GERD (21.86%) in this population-based study in Iran. By identifying modifiable risk factors, this research offers opportunities for targeted interventions and lifestyle modifications to reduce the burden of GERD.

Prevalence of oropharyngeal dysphagia symptoms in community-dwelling older adults: A community survey

BACKGROUND

Dysphagia is a common clinical condition in older adults with significant implications for health and quality of life (QOL). However, its prevalence and associated factors in the Indian community-dwelling older adults remain understudied. The present study aims at identifying the prevalence of oropharyngeal dysphagia symptoms in Indian community-dwelling older adults and identifying the age-related comorbid variables associated with an increased risk of oropharyngeal dysphagia in this population.

METHODS

Total 384 community-dwelling older adults (60 years of age or older) who were independent in performing daily activities were included in the present study. The Malayalam version of the Eating Assessment Tool-10 (EAT-10) questionnaire was used to assess individuals at risk for dysphagia. Additionally, they also completed a self-report questionnaire addressing age-related comorbid variables associated with an increased risk of oropharyngeal dysphagia.

RESULT

Using the Malayalam version of the EAT-10, the present study identified the prevalence of oropharyngeal dysphagia symptoms in 9.9% of community-dwelling older adults. Among the EAT-10 symptoms, cough while/after swallowing, difficulty swallowing solids and difficulty swallowing liquids were the most prevalent symptoms reported by participants. Increase in age and age-related comorbidities such as tooth loss, history of heart failure and digestive diseases were found to be significantly associated with the reporting of risk for dysphagia symptoms.

CONCLUSION

As dysphagia symptoms significantly impact the social, psychological and QOL of community-dwelling older adults, it is important to develop awareness about these symptoms among older adults, caretakers and physicians. Early detection and appropriate management of community-dwelling older adults at risk for dysphagia can contribute to better health outcomes and improved QOL.

Human plasma can modulate micronucleus frequency in TK6 and OE33 cells in vitro

In this paper, we studied the potential genotoxic effects of human plasma from healthy volunteers, as well as patients with gastro-oesophageal reflux disease, Barrett's oesophagus (BO) and oesophageal adenocarcinoma (OAC) using the oesophageal adenocarcinoma cell line (OE33) and the lymphoblastoid cell line (TK6). Both TK6 and OE33 cells were treated with plasma (10 % volume, replacing foetal bovine serum (FBS) or horse serum (HS)) at different time points of 4 h (for the micronucleus (Mn) assay and the invasion assay) and 24 h (for the cell cycle studies). Plasma-induced effects on DNA damage levels, cell viability and the cell cycle were studied by the micronucleus assay, cytokinesis block proliferation index (CBPI) and flow cytometry respectively. The expression of IL-8 in supernatants of TK6 cells and IFN-β in OE33 cells was also analysed by enzyme-linked immunosorbent assay (ELISA). Finally, we carried out an assessment of cellular invasion of OE33 cells following plasma treatment. The results of the micronucleus assay confirmed the genotoxicity of direct plasma treatment from some participants through the increase in DNA damage in TK6 cells. Conversely, some individual patient plasma samples reduced background levels of TK6 cell Mn frequency, in an anti-genotoxic fashion. In TK6 cells, (on average) plasma samples from patients with Barrett's oesophagus induced higher micronucleus levels than healthy volunteers (p= 0.0019). There was little difference in Mn induction when using plasma versus serum to treat the cells in vitro. Cell cycle results showed that direct plasma treatment had a marked impact on OE33 cells at 24 h (p=0.0182 for BO and p=0.0320 for OAC) by decreasing the proportion of cells in the S phase, while plasma exposure was less impactful on the cell cycle of TK6 cells. Invasion of OE33 cells was also seen to be non-significantly affected by plasma treatment of OE33 cells. The addition of N-acetyl cysteine NAC in a dose-dependent matter did not alter the formation of Mn in TK6 cells, suggesting that reactive oxygen species (ROS) are not the root cause of plasma's genotoxicity. The concentration of IL-8 in TK6 cells and IFN-β in OE33 cells was significantly higher in cells treated with OAC-derived plasma than in the untreated negative control. Collectively, our results demonstrate that plasma-specific effects are detectable which helps us better understand some important aspects of the biology of blood-based biomarkers under development.

Impact of Age on Long-Term Outcomes of Laparoscopic Nissen Fundoplication-A Single Center Study

Background and objectives: Gastroesophageal reflux disease (GERD) is a common disease affecting approximately 20% of the adult population. This study aimed to compare the results of laparoscopic Nissen fundoplication (LNF) in the treatment of GERD in patients of different age groups. Materials and Methods: A retrospective analysis was performed on patients who underwent LNF in one surgical department between 2014 and 2018. Patients were divided into three groups based on age: under 40 years of age, 40-65 years of age, and over 65 years of age. Results: A total of 111 patients (44.1% women) were analyzed in this study. The mean age was 50.2 ±15 years, and the mean follow-up was 50 months ± 16.6 months. Recurrence of symptoms occurred in 23%, 20%, and 23% in each age group, respectively (p = 0.13), and 85%, 89%, and 80% of patients from the respective groups reported that they would recommend the surgery to their relatives (p = 0.66). Furthermore, 83%, 92%, and 73% of patients from the respective age groups reported that they would undergo the surgery again with the knowledge they now had (p = 0.16). Conclusions: Given these results and observations, LNF has been shown to be a good method of treatment for GERD in every age group. In our study, there were no differences found in terms of satisfaction with surgery and associated recommendations between the studied age groups.

Main Disorders of Gastrointestinal Tract in Older People: An Overview

From a physiological standpoint, aging is a progressive reduction in each organ system’s capacity to maintain homeostasis in the face of illness or stressors. With advancing age, gastrointestinal (GI) symptoms and signs may increase, not only due to the aging processes but also to the superimposed effects of comorbidities, which can badly affect digestive functions (i.e., diabetes, malignancy, etc.) and environmental exposure. In general, gastrointestinal symptoms in older people more often underlie organic pathologies, while GI functional disorders are less frequently diagnosed in this age group. Moreover, gastrointestinal disease can also present in a nuanced and atypical manner, making the diagnostic hypothesis and, consequently, the correct diagnosis and therapy more challenging. In addition, with reference to this age group, the clinical implications of gastrointestinal pathologies can be more severe due to a decreased physiologic reserve, with a higher risk for malnutrition resulting in falls, depression, social isolation, and a deterioration of functional status. In this review, we focused on the most frequent GI tract disorders, highlighting the main age-related changes, their epidemiological, pathophysiological and clinical implications, and any differences with younger patients.

Predictors of Pathological Gastroesophageal Reflux among Emirati Patients with Reflux Symptoms Who Undergo Wireless pH Monitoring

Background: Diagnosis of gastroesophageal reflux disease (GERD) relies on recognizing symptoms of reflux and mucosal changes during esophagogastroduodenoscopy. The desired response to acid suppression therapy is reliable resolution of GERD symptoms; however, these are not always reliable, hence the need for pH testing in unclear cases. Our objective was to identify potential predictors of a high DeMeester score among patients with potential GERD symptoms to identify patients most likely to have pathological GERD. Methods: We conducted a retrospective case-control study on patients who underwent wireless pH monitoring from January 2020 to April 2022. Cases were patients with a high DeMeester score (more than 14.7), indicating pathological reflux, and controls were those without. We collected clinical and demographic data, including age, sex, body mass index (BMI), smoking status, non-steroidal anti-inflammatory drugs (NSAIDs) use, and presence of atypical symptoms. Results: 86 patients were enrolled in the study. 46 patients with high DeMeester scores were considered cases, and 40 patients with DeMeester scores less than 14.7 were considered controls. Esophagitis (grade A) was found in 41.1% of the cases and in 22.5% of the control group. In our study, age of more than 50 years compared with age of 20-29 years and being overweight appeared to be predictors of true pathological reflux among patients with reflux symptoms who underwent wireless pH monitoring. Conclusion: Age above 50 years compared with age between 20-29 years and being overweight appeared to be predictors of true pathological reflux among patients with reflux symptoms who underwent wireless oesophageal pH monitoring. The presence of oesophagitis was approximately four times more likely to be associated with true pathological reflux.

Exploring patient treatment decision making for osteoarthritis in the UAE: a cross-sectional adaptive choice-based conjoint study

OBJECTIVE

To assess osteoarthritis (OA) patients' preferences for pharmaceutical treatment via Adaptive Choice-Based Conjoint (ACBC) method.

METHODS

A United Arab Emirates (UAE) based Patient and Public Involvement (PPI) group designed the ACBC questionnaire with 10 attributes and 34 levels. The questionnaire was developed using Sawtooth Software and analyzed through Hierarchical Bayesian (HB). Results were standardized using Z-score via SPSS.

RESULTS

Study participants were 1030 OA patients, 83.6% aged 50 or older and 83.4% female. The avoidance of medication's side effects accounted for 66% relative importance compared to 6% relative importance for the medication's benefits. The "way of taking the medicine" attribute had the highest coefficient of variation (70%) and the four side effect attributes "risk of gastric ulcer, addiction, kidney and liver impairment, and heart attacks and strokes" had a coefficient of variation from 18 to 21%.

CONCLUSIONS

Arab OA patients are similar to other ethnic groups in trading-off benefits and side effects and consistently prioritizing the avoidance of medications' side effects. Although the "Way of taking medicine" was the least important attribute it was associated with the highest variation amongst patients. OA patients also prefer prescribed medications to internet-purchased and over-the-counter options.

Atopic dermatitis and risk of gastroesophageal reflux disease: A nationwide population-based study

BACKGROUND

As atopic dermatitis (AD) has been found to be related to various comorbidities as well as substantial patient burden, questions of a possible relationship between AD and nonallergic diseases beyond allergic diseases have also been raised.

OBJECTIVE

The aim of this nationwide matched cohort study was to evaluate whether AD would increase the development of gastroesophageal reflux disease (GERD).

METHODS

Patients diagnosed with AD were identified from the National Health Insurance Service-National Sample Cohort (NHIS-NSC) 2.0 database in South Korea from 2002 to 2015. Finally, 9,164 adults with AD (≥20 years old) and age, sex, household income, region of residence, disability, and baseline year-matched 9,164 controls were included in the analysis. Hazard ratio (HR) with 95% confidence interval (CI) for the development of GERD was estimated using a Cox proportional hazard regression model.

RESULTS

Overall, 12.3% of the patients in the AD group developed GERD, whereas 10.4% of the individuals in the control group developed GERD. The results of the adjusted model revealed that patients with AD had a significantly increased risk of developing GERD (adjusted HR, 1.15; 95% CI, 1.06-1.26) compared with the matched controls. Increased risk of developing GERD was consistent in subgroup analyses by sex or age groups under 60 years old as well as all the sensitivity analyses performed.

CONCLUSIONS

This study suggested that appropriate management should be considered in adults with AD to prevent GERD, because AD was found to be associated with an increased risk of subsequent GERD.

Non-neoplastic disorders in an aging gut: concise review

The spectrum of gastrointestinal (GI) issues in the older population varies from common physiological age-related changes to devastating, less common sinister pathological illness. GI system has direct exposure to external environment. Thus, it is modeled to embrace the pathophysiological changes that occur due to interaction with external factors. Gastrointestinal tract (GIT) per se is more resilient to aging as compared to other organ systems. On the other hand, elderly may present with a large plethora of GI symptoms. This presents a challenge to all echelons of medical consultation for accurate attribution for the aging process or pathophysiological causation of GI symptoms. This dichotomy leads to hindrance in adequate and appropriate treatment of GI ailments. In GI system, non-neoplastic disorders are far more common than neoplastic disorders. Hence, it becomes imperative to understand the aging evolution of the GI system and management of GI disorders in the older population.

Aging Combined with High Waist-to-Hip Ratio Is Associated with a Higher Risk of Gastro-Esophageal Reflux Disease

Background and Objective: To assess whether the combination of high waist-to-hip ratio (WHR) and elderly age is associated with higher risk of GERD. Material and Methods: A total of 16,996 subjects aged ≥20 years who received esophagogastroduodenoscopy (EGD) between January 2010 and December 2019. We evaluated the risk of GERD in different age groups and WHR groups in unadjusted analysis and multivariate logistic regression models for predictors of GERD. Results: There was a trend towards more participants with both age ≥65 years and WHR ≥ 1 (n = 129) (n = 66, 51%) than participants with age < 65 and WHR < 0.9 (n = 10,422) (n = 2814, 27%) presenting with GERD. Participants who had both age ≥ 65 years and high WHR ≥ 1 had the highest risk of any type of GERD (adjusted OR, 2.07; 95% CI, 1.44−2.96, p value < 0.05) based on multivariate logistic regression analysis. Conclusions: The combination of having a high WHR and being elderly was associated with a higher risk of GERD, and preventing central obesity in the elderly population reduced the risk of GERD and the requirement for medical resources.

Proanthocyanidins mitigate bile acid-induced changes in GSTT2 levels in a panel of racially diverse patient-derived primary esophageal cell cultures

Persistent and symptomatic reflux of gastric and duodenal contents, known as gastroesophageal reflux disease (GERD), is the strongest risk factor for esophageal adenocarcinoma (EAC). Despite similar rates of GERD and other risk factors across racial groups, EAC progression disproportionately impacts Caucasians. We recently reported that elevated tissue levels of the detoxification enzyme GSTT2 in the esophagi of Blacks compared to Caucasians may contribute protection. Herein, we extend our research to investigate whether cranberry proanthocyanidins (C-PAC) mitigate bile acid-induced damage and GSTT2 levels utilizing a racially diverse panel of patient-derived primary esophageal cultures. We have shown that C-PACs mitigate reflux-induced DNA damage through GSTT2 upregulation in a rat esophageal reflux model, but whether effects are recapitulated in humans or differentially based on race remains unknown. We isolated normal primary esophageal cells from Black and Caucasian patients and assessed GSTT2 protein levels and cellular viability following exposure to a bile acid cocktail with and without C-PAC treatment. Constitutive GSTT2 levels were significantly elevated in Black (2.9-fold) compared to Caucasian patients, as were GSTT2 levels in Black patients with GERD. C-PAC treatment induced GSTT2 levels 1.6-fold in primary normal esophageal cells. GSTT2 induction by C-PAC was greatest in cells with constitutively low GSTT2 expression. Overall, C-PAC mitigated bile-induced reductions of GSTT2 and subsequent loss of cell viability regardless of basal GSTT2 expression or race. These data support that C-PAC may be a safe efficacious agent to promote epithelial fitness through GSTT2 induction and in turn protect against bile acid-induced esophageal injury.

Quantitative assessment of multichannel intraluminal impedance pH and its clinical implications

We sought to quantify the characteristics of acid reflux episodes in patients with extraesophageal GERD symptoms (EES), hiatal hernia (HH), and erosive esophagitis (EroE) using multichannel intraluminal impedance pH (MII‐pH) and investigate the correlation between impedance parameters and high resolution esophageal manometry (HREM). This was a retrospective analysis of esophageal manometric and impedance data inpatients with typical GERD symptoms who underwent both HREM and 24 h MII‐pH tests. Within the three patient subgroups, we evaluated impedance metrics such as average height of reflux, total duration of reflux, maximum duration of reflux, average pH, and average area of reflux. We also introduce a novel composite reflux index (CRI) metric, which is a measure of reflux height, duration, and acidity. Patients with EES exhibited a 29.3% increase in average height of reflux, compared to non‐EES patients (p < 0.01); the average height of reflux was found to be an independent predictor of EES (p < 0.01). Patients with HH showed a 190% longer total reflux duration (p < 0.01, vs. non‐HH patients). Total reflux duration was twice as long in EroE patients compared to those without (p = 0.02). Average CRI was significantly different within all three subgroup comparisons (p < 0.01). Impedance metrics shared weak negative correlations with lower esophageal sphincter (LES) rest pressure and distal contractile integral (DCI), and weak positive correlations with % absent peristalsis (p < 0.05 to p < 0.01 for various parameters). Quantitative impedance metrics provide useful insight into the pathophysiology of reflux in patients with EES, HH, and EroE.

A novel movement system screen for primary care providers: a multisite, observational study

CONTEXT

Movement of the human body is essential for the interaction of an individual within their environment and contributes to both physical and emotional quality of life. Movement system disorders (MSDs) are kinesiopathologic conditions that result from either altered movement patterns, trauma, or pathology. A screening tool may facilitate earlier diagnosis and treatment of acute MSDs. This tool could prevent progression to chronic conditions, leading to better patient outcomes and quality of life.

OBJECTIVES

Our study evaluated whether a screening tool would be able to accurately screen individuals for MSDs, explore comorbidities that may predict the prevalence of MSDs, and identify why people do not discuss these problems with their primary care provider (PCP).

METHODS

A multisite, observational study in a primary care setting. Data were analyzed to determine the psychometric properties of the screening question. Logistic regression was performed to explore the relationship of comorbidities with MSDs. Thematic analysis was performed to explore why patients do not discuss these issues with their PCP.

RESULTS

The point prevalence of MSDs was determined to be 78%. The sensitivity of the screening question was determined to be good (70%). Arthritis, obesity, sleep disorders, and gastroesophageal reflux disease (GERD) were significant predictors for an MSD. Thematic analysis regarding why patients do not discuss the MSD with their physician revealed: (1) the perceived lack of importance of the problem; (2) the lack of access to healthcare, and (3) the acuity of the problem.

CONCLUSIONS

Screening for an MSD and associated comorbidities could prevent the transition of acute conditions to chronic conditions. If PCPs can identify predictors and factors associated with an MSD, they may be able to screen for MSDs more effectively. Earlier identification of MSDs may facilitate earlier treatment and prevent costs associated with resulting chronic disorders and persistent pain and disability.

Endoscopic Findings of Gastro-Esophageal Reflux Disease in Elderly and Younger Age Groups

Objective: To determine and compare the clinical features and endoscopic findings of gastro-esophageal reflux disease (GERD) in elderly and younger age groups. Materials and Methods: The clinical and endoscopic features were evaluated for all patients with GERD between January 2017 and September 2020. The criteria for inclusion were being aged over 65 and under 50 years and having an upper gastrointestinal endoscopy with reflux symptoms resistant to ppi theraphy. The exclusion criteria included prior surgery, age under 18 years, and pregnancy. The diagnosis of GERD was made according to the patients' symptoms. The SPSS 11.0 for Windows pocket program was used for statistical analysis. Results: Two hundred eighty-six patients aged over 65 years and 261 patients aged below 50 years were enrolled in this study. The mean age of the older group was 68.2 ± 4.5 years and the mean age of the young group was 38 ± 7.2 years. The male/female ratio was 5/3 and 2/1 in the young and older groups, respectively. The older patients had less severe and rare typical symptoms than the young patients. However, significantly more serious endoscopic findings were noted in the older patients compared with the younger patients. Conclusion: The older and young patients with GERD were predominantly male and typical reflux problems were less common in older patients with GERD. Older patients had more important endoscopic findings such as hernia, esophagitis, and cancer.

Aspirin Is Safe for Venous Thromboembolism Prophylaxis for Patients With a History of Gastrointestinal Issues

BACKGROUND

The safety of acetylsalicylic acid (ASA, aspirin) in patients with prior history of gastroesophageal reflux or peptic ulcer disease remains unclear. The purpose of this study was to determine the safety of ASA for venous thromboembolism (VTE) prophylaxis after total joint arthroplasty in patients with prior history of gastrointestinal (GI) issues.

METHODS

This was an institutional, retrospective cohort study of 19,044 patients who underwent primary total hip and total knee arthroplasty from 2013 to 2019. We divided the patients into two cohorts based on the presence or absence of pre-existing GI issues. Patient demographics, VTE prophylaxis, and postoperative complications were collected. The primary outcome measure was GI bleed.

RESULTS

In our series, 3090 patients had a preoperative GI issue and 15,954 did not have a GI issue. ASA was the most common mode of VTE prophylaxis (89%), followed by Coumadin (4.7%), direct oralanticoagulants (4.2%), low-molecular-weight heparin (1.7%), and others (0.4%). In the cohort of patients given ASA, there was no significant difference in postoperative GI bleeding between those with (2/1781, 0.11%) and without preoperative GI issues (8/7,628, 0.10%, P = 1.0). In the overall cohort, history of preoperative GI issues was associated with an increased risk of postoperative GI bleeding (0.32% vs 0.11%, P = .031). In logistic regression analysis, ASA was associated with a protective effect against GI bleed (OR = 0.09, 95% CI 0.01-0.40, P = .003).

CONCLUSION

ASA is safe for VTE prophylaxis after total joint arthroplasty in patients with history of GI issues and is not associated with an increased risk of postoperative GI bleeds.

Understanding the most commonly billed diagnoses in primary care: Gastroesophageal reflux disease

ABSTRACT

Gastroesophageal reflux disease (GERD) is a chronic, relapsing condition encountered commonly in primary care with an estimated worldwide prevalence of up to 33%. GERD affects all age groups, races, and genders with 25% of the population in the Western world experiencing heartburn at least once a month.

Impact of Laparoscopic Sleeve Gastrectomy on Gastroesophageal Reflux Disease and Risk Factors Associated with Its Occurrence Based Upon Quality of Life

BACKGROUND

To assess the impact of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) symptoms and to determine factors associated with the occurrence of post-LSG GERD symptoms.

MATERIAL AND METHODS

This is a retrospective study that included all obese patients who underwent LSG in Aseer Central Hospital, during the period from August 2017 to August 2019. GERD-Health-Related Quality of Life questionnaire was used to assess the patients' pre- and postoperative GERD symptoms and their satisfaction toward their general health.

RESULTS

The study included 326 patients (195 males and 131 females) with a mean age of 39.43 ± 11.17 years. Postoperatively, GERD symptoms newly developed in 105 patients (32.2%), while 25 patients out of 127 with preoperative GERD symptoms (19.69%) showed resolution of symptoms. There were significant associations (p < 0.001) between the old age, smoking and existence of comorbidities, and the occurrence of postoperative heartburn and regurgitation symptoms. Postoperatively, excess weight loss (EWL) was significantly associated with postoperative regurgitation (p = 0.045) and patients showed significant improvement in their satisfaction toward their health condition even those who developed GERD symptoms.

CONCLUSIONS

After LSG, GERD symptoms developed in about one-third of the patients while symptoms improved in only one-fifth of patients. Older patients, smokers, patients with comorbidities, and patients with more EWL had significantly worse GERD symptoms postoperatively. Weight loss rather than GERD symptoms significantly influenced patients' satisfaction toward their general health. Further prospective studies are needed to determine the relationship between weight loss and other factors associated with post-LSG reflux and overall quality of life.

Upper Gastrointestinal Bleeding

Upper gastrointestinal (GI) bleeding is a common reason for hospital admission in older adult patients and carries a high morbidity and mortality if not properly managed. Risk factors include advanced age, Helicobacter pylori infection, medication use, smoking, and history of liver disease. Patients with known or suspected liver disease and suspected variceal bleeding should also receive antibiotics and somatostatin analogues. Risk stratification scores should be used to determine patients at highest risk for further decompensation. Upper endoscopy is both a diagnostic and therapeutic tool used in the management of upper GI bleeding. Endoscopy should be performed within 24 hours of presentation after appropriate resuscitation. Management of anticoagulation in upper GI bleeding largely depends on the indication for anticoagulation, the risk of continued bleeding with continuing the medication, and the risk of thrombosis with discontinuing the medication. A multidisciplinary approach to the decision of anticoagulation continuation is preferred when possible.

Quality of Life in Gastroesophageal Reflux Disease Three Months After Laparoscopic Nissen's Fundoplication

INTRODUCTION

Gastroesophageal reflux disease (GERD) affects various elements of life including sleep, daily and social functioning, and physical and emotional activities. This study aims to determine the impact of laparoscopic Nissen's fundoplication (LNF) on health-related quality of life.

METHODS

This prospective study was conducted in a tertiary care hospital, Pakistan, from Jan 2019 to Feb 2020. Forty-seven participants completed the study. All patients completed the Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQoL) questionnaire both pre-operatively and three months after LNF.

RESULTS

There was significant difference in pre- and post-operative median Health-Related Quality of Life score (p value: 0.0073). There was improvement in items related to heartburn in HRQoL questionnaire, while questions related to swallowing and bloating either showed no change or worsening.

CONCLUSION

LNF has a significant impact on health-related quality of life. It is important for the physician to consider the impact of GERD in daily life. Management goals for GERD should also include improvement in quality of life of the patient.

Does the Formulation of Oral Solid Dosage Forms Affect Acceptance and Adherence in Older Patients? A Mixed Methods Systematic Review

OBJECTIVES

Age-related changes mean that the older population can encounter barriers toward taking medication orally. Further work is needed to identify the characteristics of oral solid dosage forms that will improve patient acceptance and adherence. The aim of this systematic review was to identify if and how formulation aspects of oral solid dosage forms affect acceptance and adherence in older people.

DESIGN

Mixed methods systematic review using a data-based convergent synthesis design.

SETTING AND PARTICIPANTS

Articles were selected if they included participants aged 60 years and older, or included health care professionals, social care professionals, and informal carers of patients aged 60 years and older.

METHODS

A systematic search of the following databases was undertaken: Web of Science, MEDLINE, Scopus, and The Cochrane Databases. The search of databases was supplemented by a search of gray literature, and reference lists of included papers were manually searched.

RESULTS

A total of 16 studies were included in the final synthesis. Three themes were generated from the thematic analysis: (1) dimensions, (2) palatability, and (3) appearance. The dimensions and palatability are often modified to improve swallowability by breaking tablets in half or taste masking with food. Polypharmacy can lead to patients using the appearance to identify tablets; however, this can lead to confusion when products appear similar. No study was identified that explored formulation characteristics across all 3 categories directly in the older population.

CONCLUSION AND IMPLICATIONS

Manufacturers should take into account practical problems older people may encounter when considering the dimensions, palatability, and appearance of the final drug product. These characteristics should be optimized to aid visual identification and swallowability. Medical providers and pharmacists have an important role in ensuring that these patient-centric drug products are prescribed and dispensed appropriately so that patients receive the most suitable formulation.

Risk assessment of obstructive sleep apnea among gastroesophageal reflux disease patients in Taif, Saudi Arabia

Background:

Previous studies have reported the association between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA).

Objectives:

The aim of the present study was to assess the prevalence of GERD among Saudi population, and to determine the risk of OSA among those diagnosed with GERD in Taif city of Saudi Arabia.

Materials and Methods:

A cross-sectional online survey was done among 843 Saudi participants using a questionnaire by collecting demographic data, weight, height, blood group, and having a previous nose or throat surgery. The GERD questionnaire and the sleep apnea symptom index were used to determine GERD and OSA prevalence.

Results:

The prevalence of GERD and OSA was 17.6% and 2.4%, respectively. A significantly higher prevalence of GERD was found among males, those with age >50 years, employees and obese participants, and those having OSA. Participants with an age >50 years and males, had a significantly higher prevalence of OSA. Being a male and older age were predictors for GERD, and the presence of GERD was an independent predictors for OSA.

Conclusion:

Future population-based studies including a representative sample of the population should be done to confirm the revealed association between GERD and OSA. It is necessary to assess GERD in patients with OSA in clinical practice.

Short- and long-term results after laparoscopic floppy Nissen fundoplication in elderly versus non-elderly patients

Background:

Laparoscopic anti-reflux surgery could be of benefit in a subset of elderly patients with gastroesophageal reflux disease. However, there are few reports that have evaluated the long-term results. This study examined the effects of age on the short- and long-term (for at least 5 years) outcomes after laparoscopic Nissen fundoplication (LNF).

Patients and Methods:

Patients were divided into four groups as follows: young (18–49); adult (50–69); and elderly (70–84), and very elderly (85–91). The database (recorded prospectively) included operating duration, conversion, intra- and early post-operative complication and late outcomes. Mean follow-up was 14.5 years (range 5–24 years).

Results:

Five hundred and sixty-nine patients met the inclusion criteria: young n = 219 (38.4%); adult n = 248 (43.5%); elderly n = 91 (16.0%) and very elderly n = 11 (1.9%). Hiatal hernia (type I and III) was significantly less frequent in young and adult patients (P < 0.0001). The operation was significantly longer in elderly and very elderly patients (P < 0.001); the use of drains (P < 0.001) and grafts (P < 0.0001) for hiatal hernia repair was less in young and adult patients. The hospital stay, conversion (5.4%), intra-operative and early post-operative complications were not influenced by age. Dysphagia was evenly distributed among the groups. Forty-eight (8.4%) patients had recurrence: 15 in the young group (6.8%), 18 in the adult group (7.2%), 11 in the elderly group (12%) and 4 in the very elderly group (36.3%) (P < 0.0001).

Conclusions:

Age does not influence short- and long-term outcomes following LNF. Control of reflux in the elderly is worse than adult patients. Therefore, ageing is a relative contraindication to LNF.

Ankylosing Spondylitis Is Associated With Risk of New-Onset Obstructive Sleep Apnea: A Nationwide Population-Based Cohort Study

Objectives: Investigating the risk of obstructive sleep apnea(OSA) among ankylosing spondylitis (AS) patients based on administrative healthcare databases.

Methods: We conducted a nationwide cohort study by using the Taiwan National Health Insurance Research Database with 1997–2013 claim records. The AS cohort included 2,210 patients who were newly diagnosed between 2003 and 2013. Randomly selected non-AS controls were matched at a 1:4 ratio. The endpoint was set as OSA occurrence or the end of 2013. Cumulative incidences, hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated after adjusting for age, gender, comorbidities, and co-medication. Multivariate analyses were performed using the Cox proportional hazards model. Due to the violation of the proportionality assumption, landmark analysis was conducted to explore the risk of OSA during specific follow-up periods.

Results: The adjusted HR (aHR) of OSA in the AS group was 2.826 (95% C.I. = 1.727–4.625) compared to the control group. On landmark analysis, aHR was 7.919 (95% C.I. = 3.169–19.792) for the AS group 0–24 months from the index date and decreased to 1.816 (95% C.I. = 0.944–3.494) at ≥ 24 months from the index date. The increased risks of OSA in the AS group compared to the control group were found for both males and females (aHRs were 4.533 and 2.672). On age-stratified analysis, a significant risk only for the 40–59 age group with aHR of 3.913 (95% C.I. = 1.890–8.102).

Conclusions: A higher risk of developing OSA was found among newly diagnosed AS cohort during the maximum 11-year follow-up period, especially within 2 years after newly diagnosed AS and in the 40–59 age group.

Depression and Anxiety in Patients with Gastroesophageal Reflux Disorder With and Without Chest Pain

Introduction Gastroesophageal reflux disease (GERD) influences patients' general health, daily and social functioning, and physical and emotional activities. It strongly affects the health-related quality of life with frequent interruptions during sleep, work, and social activities. GERD is defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. GERD symptoms are a major concern for many patients, as they cause a disturbance in physical, social and emotional health. In this study, we determine the prevalence of anxiety and depression in patients with GERD with and without chest pain. Methods In this cross-sectional study, a total of 258 consecutive patients with a diagnosis of GERD were included in this study. Of 258 participants, 112 had concerns about chest pain. Clinical presentations and comorbid disorders were evaluated by a previously validated gastroesophageal reflux symptom questionnaire. Depressive and anxious symptoms were assessed using a Hospital Anxiety/Depression Scale. Results A total of 107 (41.4%) participants had depression, 89 (34.4%) participants had anxiety, and 70 (27.13%) had both depression and anxiety. Depression and anxiety were significantly higher in patients with GERD and chest pain. Conclusion Anxiety and depression were significantly higher in patients with GERD, particularly those who also reported concerns of chest pain. Measures should be taken to reduce the stress and anxiety of GERD patients to cope with their daily life activities and improve their quality of life.

Lifestyle Modifications in Adults and Older Adults With Chronic Gastroesophageal Reflux Disease (GERD)

Gastroesophageal reflux disease (GERD) is a chronic disorder that causes the unwanted backflow of gastric contents into the esophagus, throat, and mouth. Gastroesophageal reflux disease affects roughly 20% of the US population. It is estimated that older adults experience GERD symptoms more commonly and with greater severity because of age-related physiologic changes. Comorbidities and polypharmacy, common in older adults, can also exacerbate GERD symptoms, which can allow the disease to progress. This integrative review aims to identify key lifestyle-associated risk factors and interventions appropriate for older adults with GERD. Findings can drive evidence-based collaborative best practices to care for patients in both acute and community settings with GERD. Recommendations for nursing education material that aims to address the gap of multilingual and culturally relevant GERD content will be discussed. It is likely that the prevalence of GERD will increase as the prevalence of obesity increases. It is here that registered nurses can play an instrumental role in the prevention and management of GERD in older adults by providing education, promoting health behaviors, and serving as patient advocates.

Gastrointestinal Tract Disorders in Older Age

Considering an increase in the life expectancy leading to a rise in the elderly population, it is important to recognize the changes that occur along the process of aging. Gastrointestinal (GI) changes in the elderly are common, and despite some GI disorders being more prevalent in the elderly, there is no GI disease that is limited to this age group. While some changes associated with aging GI system are physiologic, others are pathological and particularly more prevalent among those above age 65 years. This article reviews the most important GI disorders in the elderly that clinicians encounter on a daily basis. We highlight age-related changes of the oral cavity, esophagus, stomach, small and large bowels, and the clinical implications of these changes. We review epidemiology and pathophysiology of common diseases, especially as they relate to clinical manifestation in elderly. Details regarding management of specific disease are discussed in detail if they significantly differ from the management for younger groups or if they are associated with significant challenges due to side effects or polypharmacy. Cancers of GI tract are not included in the scope of this article.

Lung function parameters in patients with gastroesophageal reflux without respiratory symptoms: a case-control study

AIM

This research aimed to evaluate the effect of gastroesophageal reflux disease (GERD) on pulmonary volumes, airflows, and airway resistance in the patients without respiratory symptoms and compare them with the healthy subjects.

BACKGROUND

GERD is the return of gastric content into the esophagus and beyond. GERD may play an essential role in the extraesophageal diseases, including chest pain, asthma, laryngitis, chronic cough, and sinusitis. The relation between GERD and airway involvement in asthma and also bronchoconstrictor effects of GERD are well recognized, but its impact on lung parameters in the patients with GERD without respiratory symptoms is unclear.

METHODS

In a case-control study, 78 GERD patients without pulmonary symptoms and 93 healthy subjects as control group were enrolled. The impulse oscillometry examined airway resistance. The body plethysmograph measured the pulmonary volumes and airflows.

RESULTS

The mean age of GERD patients and the healthy subjects were 37.30±9.76 and 34.74±11.10, respectively. A total of 53.8% of patients and 67.7% of healthy subjects were male. The lung volumes measured by the body plethysmography were normal in both patients and healthy subjects. However, there was a significant difference between the groups in forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) (P=0.01) and maximal mid expiratory flow (MMEF) (P=0.008). Airway resistance at R5Hz was significantly higher in the case group than the control group (P=0.001).

CONCLUSION

The results of the current study demonstrated that GERD patients have small airway disease even in the absence of respiratory symptoms.

The use of proton pump inhibitors among older adults with intellectual disability: A cross sectional observational study

BACKGROUND

Older people with Intellectual Disability (ID) have a high prevalence of gastrointestinal conditions such as Gastro-Oesophageal Reflux Disease (GORD). However, despite this, information about treatment, in particular the use of Proton Pump Inhibitors (PPIs), in this population is sparse and limited.

OBJECTIVE

To investigate the prevalence and pattern of PPI use among older people with ID.

METHOD

Data on PPI use and key demographics was analysed from Wave 2 (2013/2014) of IDS-TILDA, a nationally representative longitudinal study of 677 participants aged 40 years and above in Ireland. Descriptive statistics, bivariate analyses and binary logistic regression were carried out.

RESULTS

Just over a quarter, 27.9% (n = 189), of participants reported use of PPIs, and 53.4% (n = 101) were female. The largest proportion of PPI users (53.4%) were aged between 50 and 64 yrs. Most of the PPIs were used in maximum doses (66.7%). However only 43.9% of PPI users had an indication for PPI use (GORD, stomach ulcer or/and an NSAID use), and further 13.2% were also taking an antiplatelet agent. Use among those in residential care homes (54.3%) was much higher than for those living independently or with family (7%). PPI use among those who have severe/profound ID was 25% higher than those with mild ID. Information about the length of PPI use was missing for 31.2%, but of those with data, just over half recorded using the PPIs for more than a year. Apart from an indication, the factors associated with PPI use were older ages (≥50 years), severe/profound level of ID.

CONCLUSION

PPI use among older people with intellectual disability is prevalent and frequently long term, often without a clear indication. PPI use especially among those with severe/profound ID and those who live in residential care homes, could predispose these individuals to additional comorbidities and in order to avoid inappropriate long term of use regular review is required.

Older Age Reduces Upper Esophageal Sphincter and Esophageal Body Responses to Simulated Slow and Ultraslow Reflux Events and Post-Reflux Residue

BACKGROUND & AIMS

It is not clear how age affects airway protective mechanisms. We investigated the effects of aging on upper esophageal sphincter (UES) and esophageal body pressure responses to slow and ultraslow simulated reflux events and post-reflux residue.

METHODS

We performed a prospective study of 11 elderly (74 ± 9 years old) and 11 young (28 ± 7 years old) healthy volunteers. Participants were placed in a supine position and evaluated by concurrent high-resolution impedance manometry and an esophageal infusion technique. Potential conditions of gastroesophageal reflux were simulated, via infusion of 0.1 N HCl and saline. UES and esophageal pressure responses were measured during the following: slow infusion (1 mL/s) for 60 seconds, 60 seconds of postinfusion dwell period, ultraslow infusion (0.05 mL/s) for 60 seconds, and 60 seconds of a postinfusion dwell period. All infusions were repeated 3 times. We used the UES high-pressure zone contractile integral (UES-CI) to determine responses of the UES.

RESULTS

Young and elderly subjects each had a significant increase in the UES-CI during slow infusions and during entire passive dwell intervals compared with baseline (P < .01, both groups). Ultraslow infusions were associated with a significant increase in UES-CI in only the young group, in the late infusion period, and into the dwell interval (P < .01). During the slow infusions and their associated dwell periods, young subjects had a higher frequency of secondary peristalsis than elderly subjects (P < .05). There was more secondary peristalsis during active infusions than dwell intervals. Secondary peristalsis was scarce during ultraslow infusions in both groups.

CONCLUSIONS

UES and esophageal body pressure responses to low-volume ultraslow reflux and associated post-reflux residue are reduced in elderly individuals. This deterioration could have negative effects on airway protection for people in this age group.

Proton pump inhibitor-refractory gastroesophageal reflux disease: challenges and solutions

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure. Pharmacologic treatments can include antacids, prokinetics, alginates, bile acid binders, reflux inhibitors, and antidepressants. Procedural options include laparoscopic fundoplication and LINX as well as endoscopic procedures, such as transoral incisionless fundoplication and Stretta. Several alternative and complementary treatments of possible benefit also exist.

Nutrition Recommendations in Elderly and Aging

Maintaining optimal health and well-being in the older adult requires understanding of how physiologic changes influence nutritional status, familiarity with the available validated tools to assess status, identification of factors predisposing older adults to malnutrition, and evidence-based practice regarding the nutritional needs of this age group. Evidence-based guidance on these core practice components is provided to the clinician in this article.

Proton pump inhibitors for the treatment of patients with erosive esophagitis and gastroesophageal reflux disease: current evidence and safety of dexlansoprazole

Gastroesophageal reflux disease is the most common upper gastroenterology disorder in the US. It is associated with a variety of complications and significantly impacts quality of life. Proton pump inhibitors are the most effective treatment. Dexlansoprazole modified release (MR) is a proton pump inhibitor that employs a novel release formulation that prolongs its absorption and allows for more flexibility in dosing. Dexlansoprazole MR can be dosed without regard to food intake or time of day, and once-daily dosing may replace twice-daily dosing of other agents. Dexlansoprazole MR is effective for healing and maintenance of erosive esophagitis, and for the treatment of nonerosive disease, including nocturnal gastroesophageal reflux disease. Dexlansoprazole MR is safe and well tolerated, and can improve quality of life.

The combined effect of age and body mass index on outcomes in foregut surgery: a regression model analysis of the National Surgical Quality Improvement Program data

BACKGROUND

In a parallel demographic phenomenon, the elderly and obese populations will become a larger part of our population and surgical practices. The elderly obese surgical risk profile is not clearly defined, although studies have confirmed their independent negative effect on surgical outcomes. Benign foregut surgery is a relatively common complex procedure performed on this demographic and warrants deeper investigation into outcomes. We investigate the synergistic effect of age and body mass index (BMI) on the outcomes of benign foregut surgery.

METHODS

Data from National Surgical Quality Improvement Program were collected for all patients undergoing foregut surgery from 2005 to 2012. Subjects were over 18 years of age and 16 BMI. Primary and secondary outcomes were 30-day mortality and overall 30-day morbidity, respectfully. Binary logistic regression models were used to assess independent and interactive effects of age and BMI.

RESULTS

A total of 19,547 patients had an average age and BMI of 57 and 29.7, respectively. Sample 30-day mortality was 0.32 %. Every 10-year age increase led to a 46 % increased odds of mortality. BMI showed a bimodal distribution with underweight and morbidly obese patients having increased mortality. The effect of BMI only became apparent with increasing age.

CONCLUSIONS

Both age and BMI are independent predictors of mortality; only older patients experienced the bimodal BMI effect. Therefore, increasing age and BMI have a synergistic effect on outcomes after foregut operations.

Gastroesophageal reflux and congenital gastrointestinal malformations

Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

Effect of a Combination of Omeprazole Plus Sustained Release Baclofen Versus Omeprazole Alone on Symptoms of Patients with Gastroesophageal Reflux Disease (GERD)

Previous studies have reported the efficacy of baclofen in the treatment of Gastroesophageal Reflux Diseases (GERD). The objective of present study is to evaluate the effect of co-administration of omeprazole 20 mg/d plus sustained Release baclofen (SR baclofen) vs. omeprazole 20 mg/d plus placebo on alleviation of symptoms in patients with a diagnosis of GERD. A prospective, double blind, placebo controlled trial included 60 patients with diagnosis of GERD have been done. Patients were randomly selected to receive either SR baclofen or a placebo in addition to omeprazole 20 mg/d for a period of 2 weeks. Patients were questioned regarding heartburn, regurgitation, chest pain and hoarseness at the base line and after 2 weeks. All patients tolerated the medications and no patients failed to complete the study due to adverse drug reactions. A total of 53 patients completed the study, 25 in SR baclofen and 28 in placebo group. After 2 weeks, 1 patient (4%) in SR baclofen group reported heartburn and regurgitation. However 13(46.4%) and 15 (53.6%) of patients in the placebo group had heartburn and regurgitation respectively. The analysis of the data shows that there is a significant difference between the two groups in heartburn and regurgitation (p < 0.0001, p < 0.0001 respectively). Statistical analysis revealed a significant difference in two groups regarding total GERD score (p <0.0001). The results of the present study suggest that a combination of SR baclofen and omeprazole may be a more effective treatment for heartburn and regurgitation than omeprazole alone.

Texture and color based image segmentation and pathology detection in capsule endoscopy videos

This paper presents an in-depth study of several approaches to exploratory analysis of wireless capsule endoscopy images (WCE). It is demonstrated that versatile texture and color based descriptors of image regions corresponding to various anomalies of the gastrointestinal tract allows their accurate detection of pathologies in a sequence of WCE frames. Moreover, through classification of single pixels described by texture features of their neighborhood, the images can be segmented into homogeneous areas well matched to the image content. For both, detection and segmentation tasks the same procedure is applied which consists of features calculation, relevant feature subset selection and classification stages. This general three-stage framework is realized using various recognition strategies. In particular, the performance of the developed Vector Supported Convex Hull classification algorithm is compared against Support Vector Machines run in configuration with two different feature selection methods.

Update on the pathogenesis and clinical treatment of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a clinically common chronic disease which seriously lowers patient's quality of life. Despite many studies on GERD, there has been no consensus regarding its pathogenesis. Various treatments have been developed and used for clinical purposes based on the traditional Chinese and Western medicine theories. This paper summarizes the recent progress in understanding the pathogenesis and clinical treatment of GERD.
