Anna Wexler
This paper focuses on the history of a portable shock-producing electrotherapeutic device known as the medical battery (1870-1920), which provided both direct and alternating current and was thought to cure a wide variety of ailments. The product occupied a unique space at the nexus of medicine, consumerism and quackery: it was simultaneously considered a legitimate device by medical professionals who practiced electrotherapeutics, yet identical versions were sold directly to consumers, often via newspaper advertisements and with cure-all marketing language...

Stem cells (SCs - stem cells) are characterized by plasticity and the ability to differentiate into other cell types. They are obtained from bone marrow, peripheral blood and cord blood. Mesenchymal stem cells (MSCs) shows a broad immunomodulating, increases the number of regulatory T cells (Treg), modifies the activity of T cells, dendritic cells and NK (natural killer). Direct impact on reducing the release of proinflammatory cytokines and increased release of proinflammatory cytokines. Within the respiratory tract has a number of resident stem and progenitor cells referred to as L-MSCs (lung mesenchymal stem cells) whose presence was confirmed by markers as defined in the trachea, epithelial cells and alveolar...

Philip C Spinella
Preventable deaths after injury must be reduced to improve outcomes for trauma patients. The elimination of preventable deaths after injury has been documented by the 75th US Army Ranger Regiment. Therefore, zero preventable deaths after injury is an achievable goal. Trauma is the most common cause of death between the ages of 1-46 and is the most common cause of life-years lost, before 75 years of age, compared to all other etiologies. Traumatic Hemorrhagic Shock (THS) is the leading cause of death that is preventable after injury, accounting for potentially 17,000 preventable deaths per year in the US...

Successful management of shock heavily relies on the ability to identify early stages of hemorrhage. During blood loss and reduced blood volume, multiple physiological mechanisms are able to compensate in order to preserve tissue oxygenation and blood flow. Unfortunately, this compensation makes the crucial early stage identification of hemorrhage complicated as traditionally monitored vital signs reflect this compensation, and do not change until significant amounts of blood have been lost. New insights and a recent body of literature utilizing a human model of hemorrhage provide evidence that it is possible to measure the body's reserve to continue to compensate for a reduced circulating blood volume...

OBJECTIVE: This study evaluates whether emergency department septic shock patients without a fever (reported or measured) receive less IV fluids, have decreased antibiotic administration, and suffer increased in-hospital mortality. DESIGN: This was a secondary analysis of a prospective, observational study of patients with shock. SETTING: The study was conducted in an urban, academic emergency department. PATIENTS: The original study enrolled consecutive adult (aged 18 yr or older) emergency department patients from November 11, 2012, to September 23, 2013, who met one of the following shock criteria: 1) systolic blood pressure less than 90 mm Hg after at least 1L IV fluids, 2) new vasopressor requirement, or 3) systolic blood pressure less than 90 mm Hg and IV fluids held for concern of fluid overload...

Parenteral beta-blocker therapy via continuous infusion has shown promising results for improved outcomes for patients with septic shock. As patients with septic shock may require multiple intravenous medications, compatibility is necessary to co-infuse these medications through a y-site connector. The purpose of this study was to examine the physical compatibility of select intravenous drugs used for patients with septic shock combined with various intravenous beta-blockers including esmolol, labetalol, and metoprolol through a simulated y-site infusion...

The cellular recycling process of macroautophagy/autophagy is an essential homeostatic system induced by various stresses, but it remains unclear how autophagy contributes to organismal stress resistance. In a recent study, we report that a mild and physiologically beneficial ("hormetic") heat shock as well as overexpression of the heat-shock responsive transcription factor HSF-1 systemically increases autophagy in C. elegans. Accordingly, we found HSF-1- and heat stress-inducible autophagy to be required for C...

BACKGROUND: Patients with nonischemic cardiomyopathy (NICM) reportedly have low incidence of appropriate shocks from wearable cardioverter-defibrillators (WCDs). A recent study questions the benefit from primary preventive implantation of implantable cardioverter-defibrillators in NICM. We therefore analyzed a subgroup of patients with NICM from the PROLONG study. HYPOTHESIS: Patients with newly diagnosed NICM show a risk for ventricular tachyarrhythmia. METHODS: The PROLONG study included 167 patients with newly diagnosed heart failure and left ventricular ejection fraction (LVEF) ≤35% with a WCD...

Phenotypic plasticity is increasingly recognized to facilitate adaptive change in plants and animals, including insects, nematodes and vertebrates. Plasticity can occur as continuous or discrete (polyphenisms) variation. In social insects, e.g. in ants, some species have workers of distinct size classes while in other closely related species variation in size may be continuous. Despite the abundance of examples in nature, how discrete morphs are specified remains currently unknown. In theory, polyphenisms might require robustness, whereby the distribution of morphologies would be limited by the same mechanisms that execute buffering from stochastic perturbations, a function attributed to heat-shock proteins of the Hsp90 family...

Intra-aortic balloon pump (IABP) is commonly used as mechanical support after cardiac surgery or cardiac shock. Although its benefits for cardiac function have been well documented, its effects on cerebral circulation are still controversial. We hypothesized that transfer function analysis (TFA) and continuous estimates of dynamic cerebral autoregulation (CA) provide consistent results in the assessment of cerebral autoregulation in patients with IABP. Continuous recordings of blood pressure (BP, intra-arterial line), end-tidal CO2, heart rate and cerebral blood flow velocity (CBFV, transcranial Doppler) were obtained i) 5 minutes with IABP ratio 1:3, ii) 5 minutes, starting 1 minute with the IABP-ON, and continuing for another 4 minutes without pump assistance (IABP-OFF)...

MicroRNAs regulate gene expression at the mRNA and translational levels. Although our previous research showed that expression of miR169 and one of its targets, NFYA5, is down- and up-regulated by drought stress, respectively, the current study shows that expression of both miR169 and NFYA5 are induced by dehydration shock. Unlike overexpression of MIR169a/b, overexpression of MIR169i/l did not decrease NFYA5 transcripts but increased NFYA5 protein levels. NFYA5 protein abundance also increased in mir169a knock-out mutants and 35S::MIR169l mir169a double mutants...

The holdase activity and oligomeric propensity of human small heat shock proteins (sHSPs) are regulated by environmental factors. However, atomic-level details are lacking for the mechanisms by which stressors alter sHSP responses. We previously demonstrated that regulation of HSPB5 is mediated by a single conserved histidine over a physiologically relevant pH range of 6.5-7.5. Here, we demonstrate that HSPB1 responds to pH via a similar mechanism through pH-dependent structural changes that are induced via protonation of the structurally analogous histidine...

Abdominal pregnancy (AP) accounts for 1% of ectopic implantations. In sub-Saharan Africa, the high prevalence of sexually transmitted infections explains the increasing frequency of this pathology. In Cameroon it rose from 1/10000 deliveries (1995) to 3.3/10000 (2015). Authors herein report a case of a viable abdominal pregnancy discovered at term during emergency laparotomy for suspected uterine rupture. The 24-year-old G2P0 patient was HIV-positive, under antiretrovirals, though AP exceptionally occurs in HIV patients...

BACKGROUND: Currently, both the step-up approach, combining percutaneous drainage (PD) and video-assisted retroperitoneal debridement (VARD), and endoscopic transgastric necrosectomy (ETN) are mini-invasive techniques for infected necrosis in severe acute pancreatitis. A combination of these approaches could maximize the management of necrotizing pancreatitis, conjugating the benefits from both the experiences. However, reporting of this combined strategy is anecdotal. This is the first reported case of severe necrotizing pancreatitis complicated by biliary fistula treated by a combination of ETN, PD, VARD, and endoscopic biliary stenting...

Introduction This prospective study reports on the impact of psychological factors on women with primary breast cancer undergoing neoadjuvant chemotherapy. These women are in a special situation, where they not only have to deal with the shock of the cancer diagnosis but also with the fact that the malignant tumor will not be removed immediately but only after completing chemotherapy. A situation like this is stressful and requires a personal strength which not every woman may have. Methods In a prospective study 53 patients were assessed using various psychological and psycho-oncological questionnaires which aimed to evaluate their psychological stress and their coping resources...

A shocking Longjiang River cadmium pollution accident occurred in 2012, the effects of which on microbial communities remain unclear. Alkaline precipitation technology was applied for remediation, but concerns rose about the stability of this technology. To understand the geographic distribution of cadmium and its correlation with microbes, in this study, 39 water samples and 39 sludge samples from this river and 2 soil samples from the nearby farmland were collected for chemical and microbial analyses. The Cd concentrations of all water samples were lower than 0...

Fos induction during learning labels neuronal ensembles in the hippocampus that encode a specific physical environment, revealing a memory trace. In the cortex and other regions, the extent to which Fos induction during learning reveals specific sensory representations is unknown. Here we generate high-quality brain-wide maps of Fos mRNA expression during auditory fear conditioning and recall in the setting of the home cage. These maps reveal a brain-wide pattern of Fos induction that is remarkably similar among fear conditioning, shock-only, tone-only, and fear recall conditions, casting doubt on the idea that Fos reveals auditory-specific sensory representations...

Short thymic stromal lymphopoietin (short TSLP), one of TSLP variants, exerts anti-inflammatory activities in endotoxin shock and colitis mouse models. Our latest work reported that short TSLP prevented house dust mite (HDM)-induced epithelial barrier disruption. Yet the role of short TSLP in toluene diisocyanate (TDI)-induced asthma is unknown. Male BALB/c mice were sensitized and challenged with TDI to generate a chemical-induced asthma model. Synthetic short TSLP peptides were given intranasally (i.n.) or intraperitoneally (i...
