Development of an Animal Model of Military-Relevant Traumatic Stress.

Introduction: Acute Stress Reactions (ASRs) affect a subgroup of individuals who experience traumatic stress. In the context of military operations, such reactions are often termed Combat and Operational Stress Reactions (COSRs). COSRs not only encompass all symptoms of ASRs but also include additional symptoms related to military combat and may develop at a rate higher than the general public experiences ASRs.

Clinical practice and volume trends of inferior vena cava filter usage at a single tertiary care center during a 19-year period.

Background: We investigated the clinical practice and volume trends of inferior vena cava filter (IVCF) usage at a single institution for an extended period and identified the potential factors affecting the clinical decision for placement, follow-up, and retrieval.

Methods: An institutional database was queried for IVCFs placed from 2000 to 2018 using the Current Procedural Terminology codes. The medical records were reviewed to evaluate the demographics, economic status, placement indication, IVCF type, follow-up evaluation for retrieval, and retrieval success rates.

Response and recovery of endocrine, behavioral, and neuronal morphology outcomes after different traumatic stressor exposures in male rats.

Preclinical models of organismal response to traumatic stress (threat of death or serious injury) can be monitored using neuroendocrine, behavioral, and structural metrics. While many rodent models of traumatic stress have provided a glimpse into select components of the physiological response to acute and chronic stressors, few studies have directly examined the potential differences between stressors and their potential outcomes. To address this gap, we conducted a multi-level comparison of the immediate and longer-term effects of two types of acute traumatic stressors.

Integration of Arts and Humanities in Medical Education: a Narrative Review.

This narrative review aims to identify and review the extant literature describing methods and outcomes of embedding the arts and humanities (AH) into medical school curricula. The Association of American Medical Colleges changed the Medical College Admission Test (MCAT) in 2015 to place new emphasis on the role of liberal arts in the process of developing well-rounded physicians. Consequently, medical schools have been implementing more connections to creative writing, literature, theater, movies, music, and the visual arts into their curricula.

Cost and clinical outcomes of postoperative intensive care unit versus general floor management in head and neck free flap reconstructive surgery patients.

Purpose: To compare clinical, surgical, and cost outcomes in patients undergoing head and neck free-flap reconstructive surgery in the setting of postoperative intensive care unit (ICU) against general floor management.

Methods: Retrospective analysis of head and neck free-flap reconstructive surgery patients at a single tertiary academic medical center. Clinical data was obtained from medical records.

Setting: Tertiary academic referral center.

Acute Sialadenitis After Skull Base Surgery: Systematic Review and Summative Practice Recommendations.

Background: Sialadenitis is a rare complication of skull base neurosurgery, in which the submandibular gland undergoes acute inflammation with edema after surgery. Although attributable to transient obstruction or manual compression, presentation may be rapidly life-threatening as a result of airway obstruction. Understanding risk factors is limited at present, and no practical management guidelines have been reported.

Characterization of novel neutralizing mouse monoclonal antibody JM1-24-3 developed against MUC18 in metastatic melanoma.

Background: MUC18 is a glycoprotein highly expressed on the surface of melanoma and other cancers which promotes tumor progression and metastasis. However, its mechanism of action and suitability as a therapeutic target are unknown.

Methods: A monoclonal antibody (mAb) (JM1-24-3) was generated from metastatic melanoma tumor live cell immunization, and high-throughput screening identified MUC18 as the target.

Fear expression is reduced after acute and repeated nociceptin/orphanin FQ (NOP) receptor antagonism in rats: therapeutic implications for traumatic stress exposure.

Rationale: Evaluation of pharmacotherapies for acute stress disorder (ASD) or post-traumatic stress disorder (PTSD) is challenging due to robust heterogeneity of trauma histories and limited efficacy of any single candidate to reduce all stress-induced effects. Pursuing novel mechanisms, such as the nociceptin/orphanin FQ (NOP) system, may be a viable path for therapeutic development and of interest as it is involved in regulation of relevant behaviors and recently implicated in PTSD and ASD.

Objectives: First, we evaluated NOP receptor antagonism on general behavioral performance and again following a three-species predator exposure model (Experiment 1).

Wide local excision prior to sentinel lymph node biopsy for primary melanoma of the head and neck.

Background: Previous wide local excision prior to sentinel lymph node biopsy (SLNB) may have the potential to disrupt lymphatic channels, thus incorrectly identifying the sentinel node. The purpose of this study was to investigate: (1) regional recurrence rates of prior wide local excision compared to other biopsy techniques and (2) survival outcomes in patients with melanoma of the head and neck.

Methods: Between the years 2000 and 2016, 391 cases were reviewed with a median follow-up time of 30 months in a large tertiary care center.

EUPATI Guidance for Patient Involvement in Medicines Research and Development (R&D); Guidance for Pharmaceutical Industry-Led Medicines R&D.

The importance and merits of greater patient involvement in medicines research and development (R&D) are commonly acknowledged and are thought to offer benefits for all involved parties. It helps to improve discovery, development, and evaluation of new effective medicines, based on the collaborative identification and understanding of unmet needs, research priorities, optimization of clinical study design, outcome measures, and endpoint development. It can result in increased transparency, trust and mutual respect between patients and other stakeholders.

EUPATI and Patients in Medicines Research and Development: Guidance for Patient Involvement in Ethical Review of Clinical Trials.

Involvement of patients in the research and development process (R&D) of new medicines-in all areas of indications-today is a widely accepted strategy in pharmaceutical industry to ensure relevance and suitability of the treatment under development. This may consist in, but is not limited to, patient input to achieve more patient-friendly protocol design, endpoint, and comparator selection as well as disease-adapted study conditions in a pre- or post-marketing clinical trial. Ethical aspects and especially the balance of benefit and risk in a clinical trial are frequently judged differently by clinical researchers, regulators, ethics committees, and patients due to their different focus.

EUPATI Guidance for Patient Involvement in Medicines Research and Development: Health Technology Assessment.

The main aim of health technology assessment (HTA) is to inform decision making by health care policy makers. It is a systematic process that evaluates the use of health technologies and generally involves a critical review of international evidence related to clinical effectiveness of the health technology vs. the best standard of care.

Impact of Providing Feed and/or Water on Performance, Physiology, and Behavior of Weaned Pigs during a 32-h Transport.

Transportation at weaning is a complex stressor made up of many factors, including withdrawal from feed and water, which can potentially negatively affect the health and welfare of pigs, especially those already experiencing weaning stress. The objective of this study was to evaluate the effect of weaning and extended transport durations (up to 32 h), with and without the provision of feed and/or water, on pig welfare. Treatment groups included: pigs neither weaned nor transported, control (CON); weaned pigs transported and provided with feed and water (T+); weaned pigs transported without feed and water (T-); weaned pigs transported with only feed (T+F); and weaned pigs transported with only water provided (TRAN+W).

Effect of Provision of Feed and Water during Transport on the Welfare of Weaned Pigs.

Transportation is a complex stressor made up of factors including weaning itself and withdrawal from feed and water. Therefore, transportation has the potential to negatively impact the health and welfare of weaned pigs. Pigs were transported for 32 h and measures of performance, physiology, and behavior were taken to assess piglet welfare.

Minority Participation and Well-Being in Majority Catholic Nations: What Does it Mean to be a Religious Minority?

This paper examines the effect of religious majority size on religious minority well-being. Religious minorities face a number of challenges ranging from deliberate discrimination to inadequate worship space and accommodations. Yet for many of the members of religious minority groups, religion remains an important part of community organizing and individual well-being.

Acute exposure to ultraviolet-B radiation modulates sex steroid hormones and receptor expression in the skin and may contribute to the sex bias of melanoma in a fish model.

Using the Xiphophorus fish melanoma model, we show a strong male bias for sunlight-induced malignant melanoma, consistent with that seen in the human population. To examine underlying factors, we exposed adult X. couchianus fish to a single, sublethal dose of UVB and measured circulating sex steroid hormones and expression of associated hormone receptor genes over a 24-h period.

Defensive aggregation (huddling) in Rattus norvegicus toward predator odor: individual differences, social buffering effects and neural correlates.

Aggregation is a defensive strategy employed by many prey species in response to predatory threat. Our group has characterized defensive aggregation (huddling) in Rattus norvegicus in response to a ball of cat fur. In this situation some rats huddle less, and approach the threatening cue more than others (active vs.

Rubbings deposited by cats elicit defensive behavior in rats.

Laboratory rats display pronounced defensive behaviors when confronted with a range of cat-derived stimuli, including collars worn by a cat, cloths rubbed on a cat, and cat fur. One possible explanation of this phenomenon (the "kairomone hypothesis") is that rats derive a survival advantage by eavesdropping on signals used by cats to communicate with each other. Cats are known to rub their bodies on objects at strategic environmental locations to signal their identity and mating potential to other cats.

An LC/MS method for the quantitative determination of 7alpha-OH DHEA and 7beta-OH DHEA: an application for the study of the metabolism of DHEA in rat brain.

Dehydroepiandrosterone (DHEA) is an important neurosteroid with neuronal protection and memory enhancement functions. 7alpha-OH DHEA and 7beta-OH DHEA are the two important metabolites of DHEA in the brain. We have developed an LC/MS method to quantitatively analyze 7alpha-OH DHEA and 7beta-OH DHEA.

Identification of a metabolite of atrazine, N-ethyl-6-methoxy-N'-(1-methylethyl)-1,3,5-triazine-2,4-diamine, upon incubation with rat liver microsomes.

Atrazine is an herbicide which has shown potential antimalarial effects both in vitro and in vivo in rats. In order to study the metabolism of atrazine in rat livers, we developed a sensitive LC/MS/MS method for the identification of atrazine and several of its metabolites. Using this method, we identified one previously unreported metabolite with a mass of 211 Da in addition to two known metabolites.
