Background A feasibility study (n = 19) evaluated the safety and initial efficacy of transoral incisionless fundoplication (TIF) for the treatment of gastroesophageal disease (GERD). The results at 1 year (n = 17) indicated that TIF was safe and had a significant effect on reducing GERD symptoms, proton pump inhibitor (PPI) usage, acid exposure, and small hiatal hernia. This study was designed to evaluate the long-term safety and durability of TIF. Methods Fourteen patients (50% female; median age, 34 years) completed the 2-year follow-up assessment tests. Three patients were excluded from the study after 1 year because two of them underwent retreatment and one was lost to follow-up. Results At 2 years, no adverse events related to TIF were reported. A C50% improvement in GERD-HRQL scores compared with those at baseline on PPIs was sustained by 64% of patients. TIF was effective in eliminating heartburn in 93% of patients and daily PPI therapy in 71% of patients. Significantly (p \ 0.05) more patients were able to consume reflux-causing foods and maintain lifestyle activities without GERD symptoms compared with baseline on PPIs. Fundoplications were durable and maintained their geometric dimensions. TIF was effective in eliminating hiatal hernia in 60% of patients and esophagitis in 55% of patients. Global assessment of all outcomes in each patient revealed that 79% of patients experienced complete cure (29%) or remission (50%) of GERD at 2 years after TIF. Conclusion The results at 2 years supported the longterm safety and durability of TIF and its sustained effect on the elimination of heartburn, esophagitis, B2 cm hiatal hernia, and daily dependence on PPIs.

Purpose:The optimal ventilatory settings in patients after cardiac arrest and their association with outcome remain unclear. The aim of this study was to describe the ventilatory settings applied in the first 72 h of mechanical ventilation in patients after out-of-hospital cardiac arrest and their association with 6-month outcomes.Methods: Preplanned sub-analysis of the Target Temperature Management-2 trial. Clinical outcomes were mortality and functional status (assessed by the Modified Rankin Scale) 6 months after randomization.Results: A total of 1848 patients were included (mean age 64 [Standard Deviation, SD = 14] years). At 6 months, 950 (51%) patients were alive and 898 (49%) were dead. Median tidal volume (V T ) was 7 (Interquartile range, IQR = 6.2-8.5) mL per Predicted Body Weight (PBW), positive end expiratory pressure (PEEP) was 7 (IQR = 5-9) cmH 2 0, plateau pressure was 20 cmH 2 0 (IQR = 17-23), driving pressure was 12 cmH 2 0 (IQR = 10-15), mechanical power 16.2 J/min (IQR = 12.1-21.8), ventilatory ratio was 1.27 (IQR = 1.04-1.6), and respiratory rate was 17 breaths/minute (IQR = 14-20). Median partial pressure of oxygen was 87 mmHg (IQR = 75-105), and partial pressure of carbon dioxide was

Background Optimal oxygen targets in patients resuscitated after cardiac arrest are uncertain. The primary aim of this study was to describe the values of partial pressure of oxygen values (PaO2) and the episodes of hypoxemia and hyperoxemia occurring within the first 72 h of mechanical ventilation in out of hospital cardiac arrest (OHCA) patients. The secondary aim was to evaluate the association of PaO2 with patients’ outcome. Methods Preplanned secondary analysis of the targeted hypothermia versus targeted normothermia after OHCA (TTM2) trial. Arterial blood gases values were collected from randomization every 4 h for the first 32 h, and then, every 8 h until day 3. Hypoxemia was defined as PaO2 < 60 mmHg and severe hyperoxemia as PaO2 > 300 mmHg. Mortality and poor neurological outcome (defined according to modified Rankin scale) were collected at 6 months. Results 1418 patients were included in the analysis. The mean age was 64 ± 14 years, and 292 patients (20.6%) were female. 24.9% of patients had at least one episode of hypoxemia, and 7.6% of patients had at least one episode of severe hyperoxemia. Both hypoxemia and hyperoxemia were independently associated with 6-month mortality, but not with poor neurological outcome. The best cutoff point associated with 6-month mortality for hypoxemia was 69 mmHg (Risk Ratio, RR = 1.009, 95% CI 0.93–1.09), and for hyperoxemia was 195 mmHg (RR = 1.006, 95% CI 0.95–1.06). The time exposure, i.e., the area under the curve (PaO2-AUC), for hyperoxemia was significantly associated with mortality (p = 0.003). Conclusions In OHCA patients, both hypoxemia and hyperoxemia are associated with 6-months mortality, with an effect mediated by the timing exposure to high values of oxygen. Precise titration of oxygen levels should be considered in this group of patients. Trial registration: clinicaltrials.gov NCT02908308, Registered September 20, 2016.
