DISCUSSION This was the first case of rhabdomyolysis reported in Chinese civil aircrew. Excessive exercise in an overweight pilot may induce rhabdomyolysis. This condition can be controlled and cured by early and effective treatment. Rhabdomyolysis could occur in a population suffering from overweight, obesity, or hyperlipidemia. This case fits in with several other cases of military pilots exercising excessively. The progression could lead to acute kidney injury without prompt and effective intervention. And common symptoms like muscular weakness or myalgia may induce sudden in-flight incapacitation, so early medical intervention should be adopted. Moreover, recurrence of rhabdomyolysis should be considered when resuming flying duties.Liu X, Meng X, Zhang C, Chen J, Li P, Wu X, Fan H. Rhabdomyolysis in a civil aviation pilot.

One of the most commonly used classes of medications to treat mental health disorders is the selective serotonin reuptake inhibitor (SSRI). Here we present a descriptive epidemiological review of SSRI use in Army aviators over a 10-yr period.METHODS An archival dataset retrieved from the U.S. Army Aeromedical Electronic Resource Office covering the years 2005 to 2015 was queried for cases of SSRI use. Frequencies were generated by primary diagnoses and aeromedical disposition for the SSRI subset of data.RESULTS A total of 114 unique cases of SSRI use were identified (122 total aeromedical outcomes). These cases included 41 waiver recommendations, 59 suspension recommendations, and 22 cases of waiver continuations. The top five most common primary diagnoses were depressive disorder (N 32), anxiety state (N 21), posttraumatic stress disorder (N 16), single major depressive episode (N 13), and adjustment disorder with depressed mood (N 12).DISCUSSION Understanding of the etiology, pathophysiology, and treatment of mental health disorders particularly within the safety-focused and unforgiving aviation environment has continued to evolve. With the application of evidence-based policy, deliberate aeromedical decision-making, and methodical risk mitigation, SSRI use does have a place within aviation. Aviators suffering in silence with deleterious impact to performance and safety or aircrew seeking services on the outside without knowledge or oversight of certification authorities must remain in the past.Kelley AM, Bernhardt K, McPherson M, Persson JL, Gaydos SJ.

The questionnaire included the simulator sickness questionnaire (SSQ) and a subjective scale to rate their confidence to fly.RESULTS In this study, 258 pilots with a median age of 31.50 yr (range, 2155 yr) and mean age of 32.61 6.56 yr participated. The prevalence of SS was 48.1% at 0H, 30.8% at 3H, and 16.4% at 6H. Based on a threshold of an SSQ score >10, the prevalence of operationally significant SS was 33.3% at 0H, 13.2% at 3H, and 8.1% at 6H. The most frequent symptoms were fatigue (38.1%), eye strain (29.0%), and fullness of head (19.9%). There was no significant difference in mean scores between rotary and fixed wing pilots. Older, more experienced pilots had greater scores at 0H, but this association did not persist. A correlation was found between SSQ score and self-reported confidence.DISCUSSION To our knowledge, this study is the first to report the prevalence of operationally significant SS in Asian military pilots over serial time points. Most pilots with SS are able to subjectively judge their fitness to fly. Sensitivity analysis suggests the true prevalence of SS symptoms at 3H and 6H to be closer to 23.8% and 12.0%, respectively.Loi JEQ, Lee MLL, Tan BBC, See B.

Elevated hs-CRP was hs-CRP values > 3 mg L1. Determinants of elevated hs-CRP were assessed using stepwise logistic regression analysis. We used the net reclassification method to evaluate the impact of hs-CRP levels on global ASCVD risk.RESULTS Of the 335 subjects (mean age 45.4 11.6 yr, 70% pilots, 99% men, 37% Caucasians), 127 individuals (39.5%) presented with elevated hs-CRP levels. Compared to those with normal hs-CRP, individuals with elevated hs-CRP were older with faster heart rate and higher blood pressure, BMI, and P wave amplitude. The proportion of individuals with elevated hs-CRP was greater among those with smoking habits, physical inactivity, MetS, tachycardia, altered P wave axis, LVH, and HT-TOD. Aging (aOR 2.15 [1.676.98]), hypertension (aOR 3.88 [2.296.58]), type 2 diabetes (aOR 6.71 [1.7710.49]), tachycardia (aOR 2.03 [1.914.53]), and LVH (aOR 2.13 [1.647.11]) were the main factors associated with elevated hs-CRP levels. Low, moderate, high, and very high risk were observed in 24 (15%), 68 (41%), 62 (37%), and 12 (7%) subjects, respectively. Including hs-CRP resulted in the net reclassification of 25% of subjects, mostly from moderate to high risk.CONCLUSION The integration of hs-CRP improved the estimation of global ASCVD risk stratification. However, a survey with a comprehensive population assessing the cost/benefit impact of such a referral is needed.Buila NB, Ntambwe ML, Mupepe DM, Lubenga YN, Bantu J-MB, Mvunzi TS, Kabanda GK, Lepira FB, Kayembe PK, Ditu SM, MBuyamba-Kabangu J-R.
