The Effects of Fat Content on the Shelf-Life of Vacuum-Packed Red Meat.

When stored at chill temperatures, vacuum-packed (VP) lamb has a much shorter shelf-life than VP beef, primarily due to its higher pH, which could be linked to the higher fat content. The higher pH would create more favourable conditions for the growth of spoilage bacteria, resulting in a shorter shelf-life of meat. To determine the effects of fat on meat shelf-life as it relates to pH, a series of shelf-life trials at 2 °C were conducted using VP beef and lamb mince with varying fat contents (i.

Student nurses' educational experiences during COVID-19: A qualitative study.

Background: Due to the COVID-19 pandemic, many unexpected changes occurred in healthcare. With the abrupt change to online education in 2020, nursing students experienced challenges with virtual learning which impacted their perception of preparedness to practice.

Spoilage potential of bacterial species from chilled vacuum-packed lamb.

The objective of this study was to establish whether specific organisms play important roles in the spoilage rate of vacuum-packed (VP) lamb at low storage temperatures. The spoilage potential of representative organisms (n = 13) of the spoilage community of VP lamb were investigated through a series of shelf-life challenge trials. Each isolate was individually inoculated onto sterile (irradiated) and non-sterile (i.

The Parasternal Long Axis View in Isolation: Is it Good Enough?

Background: Focused cardiac ultrasound (FOCUS) is a vital tool to evaluate patients at the bedside, but its use can be limited by patient habitus, sonographer skill, and time to perform the examination.

Objective: Our primary goal was to determine the diagnostic accuracy of the parasternal long axis (PSLA) view in isolation for identifying pericardial effusion, left ventricular (LV) dysfunction, and right ventricular (RV) dilatation compared with a four-view FOCUS examination.

Methods: This was a retrospective study looking at FOCUS images.

Success of implementation of a systemwide point-of-care ultrasound privileging program for emergency medicine faculty.

Objectives: Point-of-care ultrasound (POCUS) is widely used in the emergency department (ED). Not all practicing emergency physicians received POCUS training during residency, leaving a training gap that is reflected in POCUS privileging. The purpose of this study was to evaluate the success of meeting privileging criteria as well as associated factors, following implementation of a basic POCUS training and privileging program within a large emergency medicine department.

The effects of glucose on microbial spoilage of vacuum-packed lamb.

Vacuum-packed lamb produced in Australia has a shelf-life of 80-90 days under export conditions (-1 to 0 °C). However, access to some markets could involve >90 days transit time. Studies to understand the potential mechanisms of microbial spoilage of vacuum-packed lamb are, therefore, important to assist the development of shelf-life extension methods.

Design and implementation of a basic and global point of care ultrasound (POCUS) certification curriculum for emergency medicine faculty.

Point of care ultrasound (POCUS) use in the emergency department is associated with improved patient outcomes and increased patient satisfaction. When used for procedural guidance, it has been shown to increase first pass success and decrease complications. As of 2012, ultrasound has been identified as a core skill required for graduating emergency medicine (EM) residents.

Teaching Seasoned Doctors New Technology: An Intervention to Reduce Barriers and Improve Comfort With Clinical Ultrasound.

Introduction Although clinical ultrasound (CUS) is a core skill that is a requirement for emergency medicine (EM) residency graduation, only a fraction of EM practitioners who trained prior to this requirement are certified in CUS. The objective of the study was to implement a CUS workshop for practicing EM physicians, identify barriers to utilization, and assess comfort with the machine, obtaining and interpreting images, and incorporating CUS into clinical practice. Methods This was a prospective descriptive cohort study of EM physician faculty who participated in an interactive 5-hour CUS workshop intervention that introduced four core CUS modalities via didactics and hands-on scanning stations.

Abscess Size and Depth on Ultrasound and Association with Treatment Failure without Drainage.

Introduction: Skin and soft tissue infections (SSTI) occur along a continuum from cellulitis to abscess. Point-of-care ultrasound (POCUS) is effective in differentiating between these two diagnoses and guiding acute management decisions. Smaller and more superficial abscesses may not require a drainage procedure for cure.

Control of microbes on barley grains using peroxyacetic acid and electrolysed water as antimicrobial agents.

The extent and type of microbial growth on barley grain is a key determinant of malt quality for beer production, as problematic microbial products can persist into the brewing process and impact beer quality. Microbial composition on malting barley grain are influenced by field growth, storage and malting conditions. The present study investigated the efficacy of electrolysed water (EW) with free chlorine concentrations of 5, 50, 100 and 500 ppm, as well as peroxyacetic acid (PAA) at 100 and 500 ppm, as pre-steep treatments to control microbes on grains during the malting process.

Prevention and recovery in early psychosis (PREP(®)): building a public-academic partnership program in Massachusetts, United States.

Recently, there has been increasing emphasis on early intervention (EI) for psychotic disorders. EI programs in public mental health settings have been established in countries such as Australia, the United Kingdom, and Canada. However, there are relatively few EI programs in the United States (U.

The Mediating Role of Rumination in the Relation Between Quality of Attachment Relations and Depressive Symptoms in Non-Clinical Adolescents.

This study examined associations between indices of the quality of attachment relationships of adolescents with parents and peers, rumination, and symptoms of depression. More specifically, a mediation model was investigated in which rumination was hypothesized to mediate the relation between quality of attachment relations and symptoms of depression. A total of 455 high school students completed a battery of questionnaires, including quality of attachment relations, rumination, and depression.

The effects of experimentally induced rumination, positive reappraisal, acceptance, and distancing when thinking about a stressful event on affect states in adolescents.

The current study compares the effects of experimentally induced rumination, positive reappraisal, distancing, and acceptance on affect states in adolescents aged 13-18. Participants (N = 160) were instructed to think about a recent stressful event. Next, they received specific instructions on how to think about that event in each condition.

Stress-reactive rumination, negative cognitive style, and stressors in relationship to depressive symptoms in non-clinical youth.

The role of cognitive vulnerability in the development of depressive symptoms in youth might depend on age and gender. The current study examined cognitive vulnerability models in relationship to depressive symptoms from a developmental perspective. For that purpose, 805 youth (aged 10-18, 59.

Norms and screening utility of the Dutch version of the Children's Depression Inventory in clinical and nonclinical youths.

This study aimed to (a) assess relationships between the Children's Depression Inventory (CDI) and DSM-oriented depression and anxiety scales of the Youth Self Report, (b) develop reliable norms for the CDI, and (c) determine CDI cutoff scores for selecting youngsters at risk for depression and anxiety. A total of 3,073 nonclinical and 511 clinically referred children and adolescents from The Netherlands and Belgium were included. Results showed that CDI scores were significantly related to DSM-oriented symptoms of both depression and anxiety.

Dimensions of Negative Thinking and the Relations with Symptoms of Depression and Anxiety in Children and Adolescents.

The current study sought to examine three forms of negative, repetitive thinking in non-clinical children and adolescents aged between 10 and 18. More specifically, this study addressed the degree to which stress-reactive rumination can be differentiated from other forms of repetitive thinking, such as emotion-focused rumination and worry, and the associations between the various indices of repetitive thinking and symptoms of anxiety and depression. Participants completed a battery of self-report questionnaires including measures of stress-reactive rumination, emotion-focused rumination, worry, and symptoms of anxiety and depression.

The influence of emotion-focused rumination and distraction on depressive symptoms in non-clinical youth: a meta-analytic review.

This review examined evidence for some core predictions of the response styles theory (RST) concerning the relation between response styles and symptoms of depression and gender differences in the use of response styles in non-clinical children and adolescents. In summarizing the literature, effect sizes (pooled correlation coefficients) were calculated for cross-sectional and longitudinal studies. Stability of the obtained effect sizes was evaluated by means of a fail-safe N analysis.

The influence of rumination and distraction on depressed and anxious mood: a prospective examination of the response styles theory in children and adolescents.

The present study sought to test predictions of the response styles theory in a sample of children and adolescents. More specifically, a ratio approach to response styles was utilized to examine the effects on residual change scores in depression and anxiety. Participants completed a battery of questionnaires including measures of rumination, distraction, depression, and anxiety at baseline (Time 1) and 8-10 weeks follow-up (Time 2).

Blunt colon injury sustained during a kickboxing match.

Emergency physicians routinely evaluate patients for injury from blunt abdominal trauma. Most serious injuries result from high energy mechanisms such as motor vehicle collisions. This case report describes a patient who sustained blunt trauma to the descending colon during a martial arts match, necessitating a hemicolectomy.

Effects of phosphatidylinositol diphosphate on phospholipid asymmetry in the human erythrocyte membrane.

While phospholipid asymmetry has been well characterized in red blood cells (RBCs), controversy exists as to what role PIP2 plays in cation-induced phosphatidylserine (PS) exposure. We report that PIP2 can redistribute intracellular cations and thereby lead to a loss of phospholipid asymmetry. Flow cytometry was employed to monitor intracellular cation levels by using the fluorophore Fluo-3 and exposure of PS on the outer surface of the RBC bilayer by using fluorescently labeled annexin V.

An unusual complication of radial head fractures.

Radial head fractures are a fairly common injury secondary to falls on the outstretched forearm. Specific combinations of injuries involving radial head fractures and triceps tendon avulsion have been reported. Compartment syndromes secondary to distal forearm fractures are common; however fracture of the radial head rarely results in an acute compartment syndrome.

Parenteral lorazepam versus parenteral haloperidol for the control of psychotic disruptive behavior.

In a double-blind, prospective study, 2 mg of intramuscular lorazepam and 5 mg of intramuscular haloperidol were equally effective in controlling aggression, agitation, and assaultive behavior. Although lorazepam and haloperidol produced an equivalent mean decrease in aggression, significantly more subjects who received lorazepam had a greater decrease in aggression ratings than haloperidol recipients; this effect was independent of sedation. Lorazepam produced significantly fewer extrapyramidal symptoms.
