An important limitation of antireflux surgery is a 5%-10% failure rate. We investigated the correlation between various diaphragm stressors and failure of antireflux surgery. Forty-one study cases who underwent a reoperative antireflux operation from 1997 to 2001 and 50 control patients who had undergone a successful laparoscopic Nissen fundoplication during the same period without clinical or symptomatic evidence of failure were randomly selected for comparison. A retrospective analysis was conducted utilizing a standardized diaphragm stressor questionnaire, addressing the period between the primary and secondary operation. Stressors considered in the study included height, body mass index (BMI), postoperative gagging, vomiting, weight lifting (greater than 100 pounds), coughing, hiccuping, motion sickness, retching, belching, antidepressant use, smoking, preoperative grade of esophagitis, size of hiatal hernia, lower esophageal sphincter pressure, esophageal body pressures, and preoperative response to proton pump inhibitors. Of the potential stressors investigated, the following were significantly associated with surgical failure after adjusting for other variables through multivariate analysis: gagging (P = 0.005), belching (P = 0.02), and hernia size greater than 3 cm (P = 0.04; Table 1). Other potential risk factors show trends as obvious in Fig. 2. Vomiting was significant (P = 0.01) in the earlier models but lost significance when logistic regression was applied. Patients with postoperative gagging and an intraoperative hiatal hernia (greater than 3 cm) have a poorer outcome, whereas patients with postoperative belching have a better long-term outcome.

The majority of febrile neonates have negative bacterial cultures and presumed viral infections. During November 2014, four febrile neonates in southeastern Wisconsin required intensive care admission for human parechovirus (HPeV) infection in the blood and/or cerebral spinal fluid (CSF). Both vertical and horizontal transmission led to disease, and a variety of signs and symptoms, including tachycardia, hypotension, neutropenia, rash and irritability accompanied fever. All neonates recovered clinically, although concern for neurodevelopmental delay remains for those with meningoencephalitis. This case series describes the presentation and short-term outcomes of neonates requiring intensive care for HPeV infections.

Background Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual) to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity) at three ecological levels (the family, school, and community). Methods Participants were 1,323 children and their parents from 10 schools in two states. Schools were matched and randomly assigned to treatment and control. Measures of the key behaviors and body mass index were collected at baseline, immediately post-intervention, and 6 months post-intervention. Results The effect sizes of the differences between treatment and control groups ranged between small (Cohen's d = 0.15 for body mass index at 6 months post-intervention) to large (1.38; parent report of screen time at 6 months post-intervention), controlling for baseline levels. There was a significant difference in parent-reported screen time at post-intervention in the experimental group, and this effect was maintained at 6 months post-intervention (a difference of about 2 hours/week). The experimental group also showed a significant increase in parent-reported fruit and vegetable consumption while child-reported fruit and vegetable consumption was marginally significant. At the 6-month follow-up, parent-reported screen time was significantly lower, and parent and child-reported fruit and vegetable consumption was significantly increased. There were no significant effects on pedometer measures of physical activity or body mass index in the experimental group. The intervention effects were moderated by child sex (for fruit and vegetable consumption, physical activity, and weight status), family involvement (for fruit and vegetable consumption), and child body mass index (for screen time). The perception of change among the experimental group was generally positive with 23% to 62% indicating positive changes in behaviors. Conclusion The results indicate that the Switch program yielded small-to-modest treatment effects for promoting children's fruit and vegetable consumption and minimizing screen time. The Switch program offers promise for use in youth obesity prevention.
