An imported case of traumatic myiasis occurred in a soldier wounded during military action in Panama in December 1989 and evacuated to Brooke Army Medical Center, Fort Sam Houston, Texas. At the medical center, five larvae were removed from the scalp wound, reared to the adult stage, and identified as Cochliomyia hominivorax (Coquerel). Though this was the only reported case of wound myiasis of the 254 servicemen evacuated for medical treatment, this incident indicates a potential mechanism for the reintroduction of C. hominivorax into the United States.

Neurotransmitter release is triggered in microseconds by the two C domains of the Ca sensor synaptotagmin-1 and by SNARE complexes, which form four-helix bundles that bridge the vesicle and plasma membranes. The synaptotagmin-1 CB domain binds to the SNARE complex via a 'primary interface', but the mechanism that couples Ca-sensing to membrane fusion is unknown. Widespread models postulate that the synaptotagmin-1 Ca-binding loops accelerate membrane fusion by inducing membrane curvature, perturbing lipid bilayers or helping bridge the membranes, but these models do not seem compatible with SNARE binding through the primary interface, which orients the Ca-binding loops away from the fusion site.

Background: As iatrogenic hyperoxia has been related to adverse outcomes in critically ill patients, guidelines advise to titrate oxygen to physiological levels. In the prehospital setting where partial arterial oxygen (PaO) values are often not readily available, titration of oxygen is based on peripheral oxygen saturations (SpO2). In this study we aimed to investigate the efficacy of SpO guided oxygen titration in the prevention of hyperoxia.

Background: Hypertension is the leading risk factor for cardiovascular disease (CVD). Despite advances in blood pressure management, significant racial and ethnic disparities persist, resulting in higher risks of stroke, heart disease, and mortality among non-White populations. Self-measured blood pressure (SMBP) monitoring, also known as home blood pressure monitoring, has shown promise in improving blood pressure control, especially when combined with feedback from healthcare providers.

Background: Nitrous oxide (N₂O), commonly known as laughing gas, is widely recognized for its anesthetic and analgesic effects, and is frequently used in medical contexts. However, its misuse can lead to significant neurological complications, which are often under-recognized in clinical practice. Recent data on such cases in Germany are rare.

Background: Left atrial dissection is a rare and occasionally fatal complication of cardiac surgery and is defined as the creation of a false chamber through a tear in the mitral valve annulus extending into the left atrial wall. Some patients are asymptomatic, while others present with various symptoms, such as chest pain, dyspnea, and even cardiac arrest. Although there is no established management for left atrial dissection, surgery should be considered in patients with hemodynamic disruption.
