Uncontrolled results suggest that diaphragmatic breathing (DB) is effective in gastroesophageal reflux disease (GERD) but the mechanism of action and rigor of proof is lacking. This study aimed to determine the effects of DB on reflux, lower esophageal sphincter (LES), and gastric pressures in patients with upright GERD and controls.

Adult patients with pH proven upright GERD were studied. During a high-resolution impedance manometry, study patients received a standardized pH neutral refluxogenic meal followed by LES challenge maneuvers (Valsalva and abdominal hollowing) while randomized to DB or sham. After that, patients underwent 48 hours of pH-impedance monitoring, with 50% randomization to postprandial DB during the second day.

On examining 23 patients and 10 controls, postprandial gastric pressure was found to be significantly higher in patients compared with that in controls (12 vs 7 mm Hg, P = 0.018). Valsalva maneuver produced reflux in 65.2% of patients compared with 44.4% of controls (P = 0.0number of postprandial reflux events pressure by increasing the difference between LES and gastric pressure. These data further encourage studying DB as therapy for GERD.

Epidemiological studies assessing relative risk and incidence rate of esophageal cancer in patients with achalasia are scarce. We performed a long-term prospective cohort study to evaluate the risk of both squamous cell carcinoma and adenocarcinoma of the esophagus in these patients.

Between 1973 and 2018, patients with primary achalasia were followed by the same protocol including upper endoscopy with esophageal biopsies. Standardized incidence ratios (SIRs) with 95% confidence interval (CI) were used to estimate the relative risk of esophageal cancer in patients with achalasia compared with the sex- and age-matched general population.

A cohort of 566 patients with achalasia (46% men, mean age at diagnosis 48.1 years) was followed for a mean of 15.5 years since the diagnosis of achalasia. Overall, 20 patients (15 men) developed esophageal cancer 15 squamous cell carcinoma and 5 adenocarcinoma. The risk of esophageal cancer was significantly greater than the general population (SIR 104.2, 95% CI 63.7-161), and this for both squamous cell carcinoma (SIR 126.9, 95% CI 71.0-209.3) and adenocarcinoma (SIR 110.2, 95% CI 35.8-257.2). The excess risk was higher in men than women. Annual incidence rate of esophageal cancer was only 0.24% and was higher for squamous cell carcinoma (0.18%) than adenocarcinoma (0.06%).

Patients with achalasia have an excess risk of developing both squamous cell carcinoma and adenocarcinoma of the esophagus; however, this prospective cohort study confirms that the annual incidence of esophageal cancer is rather low. These findings may have implications for endoscopic surveillance of patients with achalasia.

Risk stratification has been proposed as a strategy to improve participation in colorectal cancer (CRC) screening, but evidence is lacking. We performed a randomized controlled trial of risk stratification using the National Cancer Institute's Colorectal Cancer Risk Assessment Tool (CCRAT) on screening intent and completion.

A total of 230 primary care patients eligible for first-time CRC screening were randomized to risk assessment via CCRAT or education control. Follow-up of screening intent and completion was performed by record review and phone at 6 and 12 months. We analyzed change in intent after intervention, time to screening, overall screening completion rates, and screening completion by CCRAT risk score tertile.

Of the patients, 61.7% of patients were aged <60 years, 58.7% female, and 94.3% with college or higher education. Time to screening did not differ between arms (hazard ratio 0.78 [95% confidence interval (CI) 0.52-1.18], P = 0.24). At 12 months, screening completion was 38.6% with CCRAT vs 44.0% with education (odds ratio [OR] 0.80 [95% CI 0.47-1.37], P = 0.41). Changes in screening intent did not differ between the risk assessment and education arms (precontemplation to contemplation OR 1.52 [95% CI 0.81-2.86], P = 0.19; contemplation to precontemplation OR 1.93 [95% CI 0.45-8.34], P = 0.38). There were higher screening completion rates at 12 months in the top CCRAT risk tertile (52.6%) vs the bottom (32.4%) and middle (31.6%) tertiles (P = 0.10).

CCRAT risk assessment did not increase screening participation or intent. Risk stratification might motivate persons classified as higher CRC risk to complete screening, but unintentionally discourage screening among persons not identified as higher risk.

Blink reflex (BR) under general anesthesia as an intraoperative neuromonitoring method was used to monitor facial nerves in few studies. This study aimed to test the utility of intraoperative BR during cerebellopontine angle and skull base surgeries, assess its prognostic value for facial nerve functions, and compare it with facial corticobulbar motor evoked potentials (CoMEPs).

Blink reflex and facial CoMEPs were recorded from 40 patients undergoing skull base surgeries. Subdermal needles were placed in the supraorbital notch for stimulation and in the orbicularis oculi muscle for recording the BR. A double train of 20 to 40 V intensity with an intertrain interval of 40 to 60 milliseconds, an interstimulus interval of 2.5 milliseconds, and a stimulus duration of 0.5 milliseconds were applied. Facial nerve functions were assessed with the House-Brackmann grading system in the postoperative day 1 and third-month period and correlated with intraoperative BR and CoMEPs measurements.

Of 40 patients, BR was recordable on the affected side in 32 (80%) and contralateral side in 35 (87.
