Promoting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine acceptance and uptake became necessary to achieve a high vaccination rate and subsequently herd immunity. Although the Israeli population has been largely acceptant of the SARS-CoV-2 vaccine, vaccine hesitancy has remained a major concern, especially in younger adults. We hypothesized that young adults who refused SARS-CoV-2 vaccination differed from those who have been adherent and could be characterized. Studying this specific population and recognizing individuals within this group who might be more probable to refuse vaccination can enable to target measures to further promote vaccination acceptance. ⋯ In a large cohort of enlisted IDF personnel, disparity in SARS-CoV-2 vaccine adherence was found to be related to multiple socioeconomic, educational, and military service-related variables. Although some differences were substantial, others were small and of questionable public health significance. Acknowledging these differences may enable community leaders, health care providers, and administrators to target specific populations in order to further promote SARS-CoV-2 vaccination acceptance.

Excessive gaming may be associated with sleep deprivation and self-harm. One active duty member committed self-injurious behavior to avoid work-related consequences. It was discovered that the patient participated in a video-gaming binge throughout an entire 72-hour weekend liberty. ⋯ He injured himself and fabricated a robbery and assault to avoid disciplinary consequences. Military health care providers should consider excessive gaming in patients presenting with sleep issues, self-harm, and disciplinary problems. As the prevalence of gaming increases, the military leadership should be aware that excessive gaming can degrade force readiness.

To evaluate facility postoperative opioid prescribing patterns in comparison to published guidelines and adherence to opioid safety mandates. ⋯ Most opioid prescriptions provided within the study period aligned with recommendations from author-selected guidelines. However, a review of risk prior to opioid prescribing frequently was not performed. The number of patients utilizing less than 50% of prescribed opioids, and few refills indicate that reductions in opioids prescribed would improve safety for both patients and the surrounding community without increasing the risk for the under-treatment of postoperative pain. Improved prescribing habits and patient safety will be targeted through provider education regarding risk review documentation in opioid naïve patients.

Modeling of injury risk from nonlethal weapons including flash-bangs is a critical step in the design, acquisition, and application of such devices for military purposes. One flash-bang design concept currently being developed involves multiple, area-distributed flash-bangs. It is particularly difficult to model the variation inherent in operational settings employing such devices due to the randomness of flash-bang detonation positioning relative to targets. The problem is exacerbated by uncertainty related to changes in the mechanical properties of auditory system tissues and contraction of muscles in the middle ear (the acoustic reflex), which can both immediately follow impulse-noise exposure. In this article, we demonstrate a methodology to quantify uncertainty in injury risk estimation related to exposure to multiple area-distributed flash-bang impulses in short periods of time and analyze the effects of factors such as the number of impulses, their spatial distribution, and the uncertainties in their parameters on estimated injury risk. ⋯ This work provides a methodology for exploring both the role of device parameters and the choice of dose accumulation rule in estimating the risk of significant injury and associated uncertainty for multi-impulse, area-distributed flash-bang exposures. This analysis can inform decisions about the design of flash-bangs and training for their operational usage. The methodology can be extended to other device designs or deployment concepts to generate risk maps and injury risk uncertainty ranges. This work does not account for additional injury types beyond permanent threshold shift that may occur as a result of flash-bang exposure. A useful extension of this work would be similar work connecting design and operational parameters to human effectiveness.

The beneficial effect of rivastigmine, an acetylcholinesterase inhibitor (AChEi), which increases levels of acetylcholine (ACh), was first reported in 2013. This paper replicates those findings and reports sustained symptom remission. ⋯ Low HF HRV has been reported in PTSD patients, but findings have been inconsistent. Cholinergic withdrawal could explain the disturbances in sleep, learning, and memory seen in PTSD patients. The relapse of symptoms following prolonged infection implicates the immune system as a possible initiator of the disorder. ACh and estrogen have anti-inflammatory properties, supporting a possible role of inflammation in initiating PTSD. The effect of rivastigmine treatment should be tested in properly controlled clinical trials.
