sRAGE levels were elevated during acute lung injury/acute respiratory distress syndrome, regardless of the presence or absence of severe sepsis. The plasma level of sRAGE was correlated with clinical and radiographic severity in acute respiratory distress syndrome patients and decreased over time, suggesting resolution of the injury to the alveolar epithelium. Further study is warranted to test the clinical utility of this biomarker in managing such patients and to better understand its relationship with lung morphology during acute lung injury/acute respiratory distress syndrome.
Background
Recent evidence shows accelerating worldwide adoption of social media and suggests a commensurate increase in social media use by integrated plastic surgery residency programs in the United States. Programs nationwide are now making strides to include a longitudinal social media component in their plastic surgery curriculum.
Objective
To study the use of Instagram by plastic surgery residency programs and to describe trends in adoption, volume, and content.
Methods
Current active Instagram accounts affiliated to integrated plastic surgery residency programs were surveyed to identify date of first post, number of posts, number of followers, number of following, engagement rate, most liked posts, and content of posts. All data was collected on May 12, 2020.
Results
Sixty-nine out of eighty-one (85.2%) integrated plastic surgery residency programs had Instagram accounts, totaling 5,544 posts. This represents an absolute increase in program accounts of 392% since 2018. The 100 most liked posts were categorized as: forty-six as Promotion of the Program/Individual, thirty-two as Resident Life, fourteen as Promotion of Plastic Surgery, and eight as Education.
Conclusion
Instagram use by plastic surgery residency programs has drastically increased since it was first evaluated in 2018. This trend will continue as we reach near saturation of residency programs with accounts. We remain steadfast in our belief that the advantages of social media use by plastic surgeons and trainees are far outweighed by the potential community-wide impacts of violations on peers, patients, and the general public.
Laparoscopic surgery technology continues to advance. However, much less attention has been focused on how alteration of the laparoscopic surgical environment might improve clinical outcomes. We conducted a randomized, 2 × 2 factorial trial to evaluate whether low intraperitoneal pressure (IPP) (8 mmHg) and/or warmed, humidified CO2 (WH) gas are better for minimizing the adverse impact of a CO2 pneumoperitoneum on the peritoneal environment during laparoscopic surgery and for improving clinical outcomes compared to the standard IPP (12 mmHg) and/or cool and dry CO2 (CD) gas. Herein we show that low IPP and WH gas may decrease inflammation in the laparoscopic surgical environment, resulting in better clinical outcomes. Low IPP and/or WH gas significantly lowered expression of inflammation-related genes in peritoneal tissues compared to the standard IPP and/or CD gas. The odds ratios of a visual analogue scale (VAS) pain score >30 in the ward was 0.18 (95% CI: 0.06, 0.52) at 12 hours and 0.06 (95% CI: 0.01, 0.26) at 24 hours in the low IPP group versus the standard IPP group, and 0.16 (95% CI: 0.05, 0.49) at 0 hours and 0.29 (95% CI: 0.10, 0.79) at 12 hours in the WH gas group versus the CD gas group.
IntroductionTracheal intubation and anaesthesia promotes lung collapse and hypoxemia. In acute lung injury patients, recruitment maneuvers (RMs) increase lung volume and oxygenation, and decrease atelectasis. The aim of this study was to evaluate the efficacy and safety of RMs performed immediately after intubation.MethodsThis randomized controlled study was conducted in two 16-bed medical-surgical intensive care units within the same university hospital. Consecutive patients requiring intubation for acute hypoxemic respiratory failure were included. Patients were randomized to undergo a RM immediately (within 2 minutes) after intubation, consisting of a continuous positive airway pressure (CPAP) of 40 cmH2O over 30 seconds (RM group), or not (control group). Blood gases were sampled and blood samples taken for culture before, within 2 minutes, 5 minutes, and 30 minutes after intubation. Haemodynamic and respiratory parameters were continuously recorded throughout the study. Positive end expiratory pressure (PEEP) was set at 5 cmH2O throughout.ResultsThe control (n = 20) and RM (n = 20) groups were similar in terms of age, disease severity, diagnosis at time of admission, and PaO2 obtained under 10-15 L/min oxygen flow immediately before (81 ± 15 vs 83 ± 35 mmHg, P = 0.9), and within 2 minutes after, intubation under 100% FiO2 (81 ± 15 vs 83 ± 35 mmHg, P = 0.9). Five minutes after intubation, PaO2 obtained under 100% FiO2 was significantly higher in the RM group compared with the control group (93 ± 36 vs 236 ± 117 mmHg, P = 0.008). The difference remained significant at 30 minutes with 110 ± 39 and 180 ± 79 mmHg, respectively, for the control and RM groups. No significant difference in haemodynamic conditions was observed between groups at any time. Following tracheal intubation, 15 patients had positive blood cultures, showing microorganisms shared with tracheal aspirates, with no significant difference in the incidence of culture positivity between groups.ConclusionsRecruitment maneuver following intubation in hypoxemic patients improved short-term oxygenation, and was not associated with increased adverse effects.Trial registrationNCT01014299
