Lactulose Hydrogen Breath Test Result Is Associated with Age and Gender

Small intestinal bacterial overgrowth (SIBO) is associated with chronic gastrointestinal diseases and structural/functional abnormalities of the gastrointestinal tract. SIBO’s association with clinical characteristics is unclear. This study investigates the association between clinical factors and SIBO according to lactulose hydrogen breath test (LHBT) result. Methods. A cross-sectional study in a university-based gastroenterology practice was performed. Data was abstracted from the medical records of subjects undergoing LHBT from 6/1/2009 to 6/1/2013. Logistic regression analysis was performed to determine the association between predictor variables: age, sex, body mass index (BMI), and positive LHBT, the outcome of interest. Results. LHBT was performed in 791 subjects. Fifty-four percent had a positive LHBT. There was no statistically significant difference between the LHBT results according to age or BMI. In females, the likelihood of a positive LHBT increased with age (OR 1.02; 95% CI: 1.01–1.03). In males, the likelihood of a positive LHBT result decreased with age (OR 0.98; 95% CI: 0.97–1.00). Conclusion. There was an association between age, with respect to sex, and a positive LHBT. With increased age in females, the odds of a positive LHBT increased, while, in men, the odds of a positive LHBT decreased with age

Implications of Protein and Sarcopenia in the Prognosis, Treatment, and Management of Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a common cause of chronic liver disease globally, with prevalence rapidly increasing in parallel with rising rates of obesity and metabolic syndrome. MASLD is defined by the presence of excess fat in the liver, which may induce inflammatory changes and subsequent fibrosis in high-risk patients. Though MASLD occurs frequently, there is still no approved pharmacological treatment, and the mainstay of therapy remains lifestyle modification via dietary changes, enhancement of physical activity, and management of metabolic comorbidities. Most nutrition research and clinical guidance in this disease centers on the reduction in fructose and saturated fat in the diet, although the emerging literature suggests that protein supplementation is important and implicates muscle mass and sarcopenia in disease-related outcomes. This review will assess the current data on these topics, with the goal of defining best practices and identifying research gaps in care

Intermittent fasting improves hepatic end points in nonalcoholic fatty liver disease: A systematic review and meta-analysis

Background and Aims:. Despite NAFLD being the most prevalent liver disease globally, currently there are no FDA-approved treatments, and weight loss through caloric restriction and enhanced physical activity is the recommended treatment strategy. Intermittent fasting (IF) has been proposed as an alternative strategy with additional cardiometabolic benefits. In this systematic review and meta-analysis, we evaluated the anthropometric, biochemical, and hepatic impacts of IF in patients with NAFLD. Methods:. MEDLINE, EMBASE, Cochrane Central, and conference abstracts were searched for IF interventions in adults with NAFLD until April 2, 2023. Meta-analysis with a random effects model was used to compare pre-intervention and post-intervention changes in anthropometric, biochemical, and hepatic end points in the IF intervention group with the control group. Publication bias was assessed using Egger’s test. Results:. Fourteen studies were included in the systematic review and ten in the meta-analysis (n = 840 participants, 44.64% male). Studies varied in modalities for NAFLD diagnosis, duration of IF (4–52 weeks), and type of IF (5:2 diet, modern alternate-day fasting, time-restricted eating, or religious fasting). Body weight, body mass index, and waist to hip ratio all significantly improved following fasting intervention (p< 0.05). Adults with NAFLD showed an improvement in serum alanine transaminase, aspartate aminotransferase, hepatic steatosis (controlled attenuation parameter measured by vibration-controlled transient elastography), and hepatic stiffness (measured by vibration-controlled transient elastography) after fasting intervention (p < 0.05). Conclusions:. There is limited, but moderate- to high-quality evidence to suggest that IF can improve hepatic end points and promote weight loss in adults with NAFLD. Larger randomized controlled studies with extended duration are needed to further validate our findings

AGA Institute Quality Indicator Development and Uses

The Affordable Care Act, which was signed into law in 2010, established several national priorities for health care delivery, including reinforcing the importance of high-value health care. Cost and quality are fundamental functions of value. Although costs may be clearly definable, quality can be more elusive to calculate and measure. The use of structured quality measures, which are standardized tools to quantify health care processes and outcomes, can reduce variability in quality reporting. One prominent example of a gastroenterology-focused quality measure is the adenoma detection rate, which reflects the percentage of average-risk screening colonoscopies in which at least 1 adenoma is detected. Like adenoma detection rate, all quality measures require discrete specifications for calculating a numerator and denominator to allow widespread standardization and reliable measurement across practices. Ultimately, this reproducibility permits the establishment of benchmark targets, which in turn allow insights into variable measure adherence and opportunity to develop and implement improvement
