RESUMEN
GOALS: To investigate the time trends of the prevalence and predictors of acute gastroenteritis (AGE) in the United States from 2005 to 2014 using nationally representative data. BACKGROUND: AGE results in numerous visits to emergency departments and outpatient clinics annually in the United States with the estimated attributable cost to the US economy up to $145 billion dollars. However, time trends and predictors of AGE are not fully understood. METHODS: Data were obtained from the National Health and Nutrition Survey (NHANES) 2005 to 2014, a nationally representative health survey. AGE was defined by a medical question (Do you have a stomach or intestinal illness with vomiting or diarrhea that started during last 30 d?). Prevalence of AGE was estimated in the total population as well as by selected demographic variables. Predictors of AGE and time trends of prevalence over survey periods were also investigated. RESULTS: Overall monthly prevalence of AGE was 8.31% (95% confidence interval, 7.81-8.81), corresponding to 22.8 million people. AGE was associated with a younger age group, the highest in ages 0 to 9 years old, females, winter to early spring season, US born, divorced/separated/widowed individuals, current smokers, heavy alcohol users, and low household income. In the trends analyses, the prevalence of AGE significantly decreased over the study periods: 10.23% in 2005 to 2006, 9.89% in 2007 to 2008, 7.58% in 2009 to 2010, 6.44% in 2011 to 2012, and 7.47% in 2013 to 2014 (trend P<0.001). CONCLUSION: In the United States from 2005 to 2014, the monthly prevalence of AGE was 8.31% and has been significantly decreasing over time.

BACKGROUND: Despite unclear benefits of gluten-free diets (GFD) in the general population, gluten-free followers without medical indications are driving the market. Few studies have investigated health benefits of GFD in the general population. AIMS: To estimate metabolic and cardiovascular disease (CVD) risk profiles among gluten-free followers without celiac disease (CD). METHODS: Data were obtained from the National Health and Nutrition Examination Survey (NHANES) 2009-2014. There were 13,523 persons without CD who had GFD information. People with known CVD were excluded. We compared gluten-free followers without CD and the general population by selective metabolic and CVD risk profiles using survey-weighted generalized logistic regression. RESULTS: There were 155 gluten-free followers without CD and CVD, corresponding to a weighted prevalence of 1.3% (3.2 million Americans). Gluten-free followers tended to be women and have a smaller waist circumference and higher HDL cholesterol. They also had a lower BMI with a borderline p value (0.053) and significant self-reported weight loss (-1.33 kg) over one year. Moreover, gluten-free followers were more likely to consider their weight appropriate. There was no statistical difference by age, smoking, hypertension, total cholesterol, triglyceride cholesterol, HbA1c, or fasting glucose. Despite a lower probability of having metabolic syndrome (33.0 vs 38.5%) and lower 10-year CVD risk score (4.52 vs 5.70%) in gluten-free followers, there was no statistical difference. CONCLUSIONS: Although being on a GFD may be beneficial in weight management, there was no significant difference in terms of prevalence of metabolic syndrome and CVD risk score in gluten-free followers without CD.

The goal of this review was to compare long-term oncologic outcomes of robotic versus laparoscopic resection of colorectal cancer. A literature search was performed using PubMed, EMBASE, Cochrane, and Medline (2002-2014). Search terms: laparoscopic, robotic, rectal, colon, surgery, oncologic, and outcomes. Studies comparing overall and disease free survival of robotic versus laparoscopic surgery for colorectal cancer were included. Meta-analysis was performed using OpenMeta[Analyst] for Windows 8. Five studies were identified reporting on overall survival, disease free survival, lymph node extraction, and distal and circumferential resection margin. Three hundred and seventeen patients underwent robotic resection and 368 underwent laparoscopic resection, with similar demographics. Operative times were longer with robotic resections, with no difference in estimated blood loss (EBL) or length of stay. The disease stage was distributed similarly in both groups. Similar numbers underwent neo-adjuvant therapy. Laparoscopic resection was associated with 3.2 mm larger distal resection margins (p = 0.04) and 2.2 more lymph nodes removed (p = 0.001), but with equivalent circumferential resection margin status. Disease-free and overall survival was equivalent. Robotic and laparoscopic surgery for colorectal cancer offer comparable overall and disease free survival. Laparoscopic surgery offered a slight advantage in operative time, distal margin, and lymph node yield. Larger, prospective trials are needed to confirm the equivalence of these approaches.
