Introduction: Several studies identified a link between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA). GERD is a condition in which acid reflux from the stomach to the esophagus causes troublesome symptoms. On the other hand, OSA is defined as a sleep-related breathing disorder in which airflow significantly decreases or ceases due to upper airway obstruction, leading to arousal from sleep. OSA was found to be associated with GERD. In this study, we aim to study the characteristics and concurrent risk factors associated with GERD and OSA in a large population-based study.Methods: Patients with the diagnosis of GERD were extracted from the National Inpatient Database (NIS) for the years 2016 to 2019. Patients' age, gender, race, and hospital information, including region and bed size, were extracted and considered as baseline characteristics. The comorbidities included are hypertension (HTN), atrial fibrillation (AFib), congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PHTN), obesity, and smoking. Patients younger than 18 years old were excluded from this study.Results: Out of 22,677,620 patients with the diagnosis of GERD, 12.21% had a concurrent diagnosis of OSA (compared to 4.79% in patients without GERD, p-value <0.001). The mean age of patients with GERD and OSA was 64.47 years vs 65.42 years in patients without OSA (p-value <0.001). The GERD and OSA group had almost identical gender distribution compared to the GERD only group, as it was predominantly female patients. The white and black races were slightly more prevalent in the GERD and OSA group compared to the GERD only group. Regarding comorbidities, the prevalence of obesity was more clear in the GERD and OSA group. It was noted that the group of patients who carry a diagnosis of GERD and OSA have more prevalence of diabetes (DM), hypertension (HTN), obesity, atrial fibrillation (Afib), congestive heart failure (CHF), and pulmonary hypertension (PHTN). Patients with GERD and OSA were 21% less likely to be older than 65 years rather than younger (95% CI: 0.79-0.8, p-value <0.001), 35% less likely to be females (95% CI: 0.65-0.65, p-value <0.001), and 22% less likely to be non-white (95% CI: 0.77-0.8, p-value <0.001). Obesity was found to be the strongest association with this population, followed by PHTN, CHF, DM, HTN, Afib, and lastly smoking.Conclusion: Patients with GERD and OSA were found more likely to be female, white, living in the southern part of the United States, obese, diabetes mellitus type 2, and being active smokers.

In patients with a functional gastrointestinal (GI) tract, enteral feeding is preferred over parenteral feeding as it has fewer complications and a relatively lower cost. Nasogastric and nasoenteric feeding tubes are available options but when long-term enteral feeding is desired, a percutaneous endoscopic gastrostomy (PEG) tube is more convenient. PEG tube can be associated with multiple complications; however, its displacement which causes gastric outlet obstruction (GOO) is a rare one. Here we present a case of an 81year-old woman with dementia who presented with upper GI bleeding and was found to have GOO causing reflux esophagitis due to PEG tube displacement.

IntroductionAspirin has been associated with a reduction in mortality in patients diagnosed with colorectal cancer (CRC). A possible mechanism for this is related to the programmed cell death 1 (PD-1) immune checkpoint pathway. Aspirin may have a synergistic effect with PD-1 inhibitors via inhibition of prostaglandin E2 (PGE2) production, which can reverse the ability of tumor cells to evade the immune system. This appears to be strongest in cancers that express PI3 kinase (PI3K) signaling activity, which aspirin downregulates. However, the benefit of pre-diagnosis aspirin use on CRC overall survival (OS) and cancer-specific survival is still controversial, and most studies have been performed in racially homogenous populations. Our study examines the effect of pre-diagnosis aspirin therapy on OS in a racially diverse group of patients with CRC. MethodsThis is a retrospective chart review of 782 patients diagnosed with CRC from January 2007 to December 2020. Kaplan-Meier curve was created to study the association of aspirin exposure compared to no exposure on OS. In addition, univariate and multivariate binary logistic regression analyses were done to investigate potential predictors of survival. ResultsOf the 782 patients with CRC, 55.1% were males, 22.2% whites, 58.5% Asians, and 17.7% Pacific-Islanders. Moreover, 38.4% of the patients had a history of aspirin use, 79% of them used it for more than one year. There were more patients with hypertension (HTN), hyperlipidemia (HLD), diabetes mellitus (DM), and chronic kidney disease (CKD) among those with a history of aspirin use.There was no difference in one, three, and five-year OS among aspirin users compared to non-users, p-value = 0.63. Age, grade, and stage were potential predictors of worsened OS. However, treatment with chemotherapy and CKD were potential predictors of worsened OS on univariate analysis only. No significant association was noticed with gender, tumor location, or other associated comorbidities. ConclusionThe effect of pre-diagnosis aspirin use on CRC survival is not clear. In this retrospective analysis of a racially diverse population of CRC patients, we found that aspirin use was not associated with improved OS. Therefore, physicians should be careful about using aspirin as adjuvant therapy in CRC patients until highquality prospective data are available, given the potential associated complications.
