Addressing tense and escalating situations with noncoercive measures is an important element of inpatient psychiatric treatment. Although restraint rates are frequently monitored, the use of pro re nata (PRN) intramuscular (IM) injections to address agitation is also an important indicator. In 2015, at the current study site, a significant increase was noted in PRN IM medication use despite unit leadership's efforts to build a culture of trauma-informed care (TIC). The purpose of the current quality improvement project was to educate staff on methods to incorporate TIC into daily practice and the use of brief solution-focused therapy techniques in escalating situations...

OBJECTIVE: Animal models are frequently used to examine stress response but experiments seldom include females. The connection between the microbiota-gut-brain axis and behavioral stress response is investigated here using a mixed-sex mouse cohort. METHODS: CF-1 mice underwent alternating days of restraint and forced swim for 19 days (Male N=8, Female N=8) with matching numbers of control animals at which point the 16S rRNA genes of gut microbiota were sequenced...

Refinement is a critical step in the determination of a model which explains the crystallographic observations and thus best accounts for the missing phase components. The scattering density is usually described in terms of atomic parameters; however, in macromolecular crystallography the resolution of the data is generally insufficient to determine the values of these parameters for individual atoms. Stereochemical and geometric restraints are used to provide additional information, but produce interrelationships between parameters which slow convergence, resulting in longer refinement times...

Refinement is a process that involves bringing into agreement the structural model, available prior knowledge and experimental data. To achieve this, the refinement procedure optimizes a posterior conditional probability distribution of model parameters, including atomic coordinates, atomic displacement parameters (B factors), scale factors, parameters of the solvent model and twin fractions in the case of twinned crystals, given observed data such as observed amplitudes or intensities of structure factors...

Although minimally invasive pancreatectomy has been performed increasingly for pancreatic malignancies, many authors feel that a history of pancreatitis is a contraindication to either laparoscopic or robotic-assisted pancreatectomy. Shown here is a video (Supplemental Digital Content 1, of a laparoscopic total pancreatectomy with splenectomy for chronic pancreatitis. This patient was denied auto-islet cell transplantation because of insurance restraints. In total, 4 laparoscopic total pancreatectomies have been attempted and completed...

Classifying eating disorders in youth is challenging in light of developmental considerations and high rates of diagnostic migration. Understanding the transactional relationships among eating disorder symptoms, both across the transdiagnostic spectrum and within specific diagnostic categories, may clarify which core eating disorder symptoms contribute to, and maintain, eating-related psychopathology in youth. We utilized network analysis to investigate interrelationships among eating disorder symptoms in 636 treatment-seeking children and adolescents (90...

While great progress has been made, only 10% of the nearly 1,000 integral, α-helical, multi-span membrane protein families are represented by at least one experimentally determined structure in the PDB. Previously, we developed the algorithm BCL::MP-Fold, which samples the large conformational space of membrane proteins de novo by assembling predicted secondary structure elements guided by knowledge-based potentials. Here, we present a case study of rhodopsin fold determination by integrating sparse and/or low-resolution restraints from multiple experimental techniques including electron microscopy, electron paramagnetic resonance spectroscopy, and nuclear magnetic resonance spectroscopy...

We investigated the effects of chewing on the anterior and posterior insular cortices during restraint stress using phosphorylated extracellular signal-regulated kinase (pERK) levels as a marker of neuronal responses. The stress only group demonstrated increased numbers of pERK-immunoreactive cells in both the anterior and posterior insular cortices compared to the control group (p < 0.01). In the stress with chewing group, the stress-induced increase of pERK-immunoreactive cell numbers was suppressed in both insular cortices and these differences were statistically significant compared to the stress-only group (p < 0...

Motor vehicle collisions (MVCs) are a significant cause of pediatric morbidity, particularly in low- to middle-income countries. We describe car seat use in children on the USA-Mexico border. A retrospective review was conducted for children 0-9 years old, admitted to the region's only Level I trauma center. Simultaneously, data were obtained from the SAFE KIDS database, a program that encourages car seat use through city checkpoints. There were 250 MVC admissions and nine fatalities in children 0-9 years old from 2010 to 2015...

Restrictive practices continue to be used in mental health care despite increasing recognition of their harms and an international effort to reduce and ultimately eliminate their use. The aim of this qualitative study was to explore mental health nurses' views of the potential elimination of these practices. Nine focus groups were conducted with 44 mental health nurses across Australia, and the data analysed using thematic analysis. Overall, the nurses expressed significant fear about the potential elimination of restrictive practices and saw themselves as being blamed for both the use of these practices and the consequences should they be eliminated...

Stressors activate the hypothalamic-pituitary-adrenal (HPA) axis and immune system eliciting changes in cognitive function, mood and anxiety. An important link between stress and altered behavior is stimulation of the Kynurenine Pathway which generates neuroactive and immunomodulatory kynurenines. Tryptophan entry into this pathway is controlled by rate-limiting indoleamine/tryptophan 2,3-dioxygenases (DOs: Ido1, Ido2, Tdo2). Although implicated as mediating changes in behavior, detecting stress-induced DO expression has proven inconsistent...

The activity of CTP:phosphocholine cytidylyltransferase (CCT), a key enzyme in phosphatidylcholine synthesis, is regulated by reversible interactions of a lipid-inducible amphipathic helix (domain M) with membrane phospholipids.  When dissociated from membranes a portion of the M domain functions as an auto-inhibitory (AI) element to suppress catalysis.  The AI helix from each subunit binds to a pair of α-helices (αE) that extend from the base of the catalytic dimer to create a four-helix bundle. The bound AI helices make intimate contact with loop L2, housing a key catalytic residue, Lys-122...

Recent research has demonstrated that certain components of body image (i.e., shape and weight over-evaluation, preoccupation, and dissatisfaction) in secondary school students shared a distinct clinical significance because of their differential relation to measures of psychopathology. The present study aimed to replicate and extend on these findings by examining the distinctiveness of these body image constructs, in addition to a fear of weight gain, in individuals with anorexia nervosa (AN)-a disorder this is facilitated and maintained by extreme body image concerns...

OBJECTIVE: Virgin coconut oil (CO) and treadmill exercise have been reported to improve memory performance in young rats. CO has also been associated with antistress properties in young, stressed mice. Therefore, in this study we aimed to investigate whether CO and treadmill exercise could synergistically ameliorate the effects of chronic stress on anxiety-like behavior and episodic-like memory in young rats. METHODS: The rats received CO and were exercised (Ex) from the 15th to the 45th day of life...

Hematology is an important health indicator in birds, but the stress from capture or anesthesia can cause alterations in blood count. This study aimed to evaluate the differences found in blood counts among guans ( Penelope obscura) under physical restraint and anesthetized with isoflurane. Thirty-two free-range guans from the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA) Park were enrolled in the study. After physical restraint, blood samples were obtained from the ulnar vein and placed in heparinized tubes...

BACKGROUND: With long-standing and widespread high rates of errors in child restraint use, there is a need to identify effective methods to address this problem. Information supplied with products at the point of sale may be a potentially efficient delivery point for such a countermeasure. The aim of this study is to establish whether product materials developed using a consumer-driven approach reduce errors in restraint use among purchasers of new child restraint systems. METHODS: A cluster randomised controlled trial (cRCT) will be conducted...
