BACKGROUND Several risk factors contribute to the inflammation promoting hepatocellular carcinoma (HCC) development, but the underlying mechanisms are unknown. Human endogenous retrovirus H long terminal repeat-associating 2 (HHLA2), a B7 family member, is highly expressed in various malignant tumor tissues and is related to tumor progression and metastasis. MATERIAL AND METHODS Bioinformatics analysis was used to analyze the gene expression chip GSE33006 of HCC tissue in the GEO database, draw a heat map of differentially expressed genes, and analyze the GO pathway of gene function annotation. Then, we compared HCC tissues with para-carcinoma liver tissues from 55 patients for expression patterns and associations with HHLA2. Effects of HHLA2 knockdown were examined in the human HCC cell line HepG2 to explore effects of HHLA2 on HepG2 cells. RESULTS A significantly higher expression of HHLA2 at the mRNA and protein levels was detected in HCC tissues than in para-carcinoma liver tissues, which was similar to HHLA2 expression in the GSE33006 data. A higher expression of HHLA2 protein was associated with advanced cancer stage, tumor differentiation, and invasion of adjacent structures. In vitro knockdown of HHLA2 expression significantly increased HepG2 cell adhesion, promoted cell apoptosis, induced cell cycle arrest in the G1/S phase, and inhibited cell proliferation, migration, and invasion. CONCLUSIONS Our data indicated there was a higher expression of HHLA2 in HCC tissues than in para-carcinoma liver tissues, and HHLA2 plays a major role in the development and progression of HCC. Owing to its higher expression, HHLA2 is a potential prognostic biomarker for HCC.BACKGROUND Clozapine, a second-generation antipsychotic, is often prescribed for refractory schizophrenia; however, it can cause life-threatening adverse events including agranulocytosis and myocarditis. Making the diagnosis of clozapine-induced myocarditis can be challenging given the non-specific presentation as well as risk involved in obtaining an endomyocardial biopsy. As clozapine-induced myocarditis carries a mortality risk of up to 30%, timely recognition, diagnosis, and management are vital. This report presents a case of clozapine-induced myocarditis in a 25-year-old man with refractory schizophrenia who was diagnosed using non-invasive imaging with cardiovascular magnetic resonance (CMR). CASE REPORT A 25-year-old man with refractory schizophrenia was admitted with severe psychotic symptoms and started on a rapid titration of clozapine. During his hospitalization he developed somnolence, fever, and tachycardia with leukocytosis, elevated inflammatory markers, and cardiac biomarkers concerning for clozapine-induced myocarditis. Alternative etiologies were ruled out and CMR was used to confirm the diagnosis. The patient's symptoms resolved following discontinuation of clozapine and initiation of supportive therapies. CONCLUSIONS Clozapine-induced myocarditis is challenging to diagnose due to a lack of consensus on diagnostic criteria, reliance on voluntary reporting, and non-specific presentation. This report highlights that myocarditis can be associated with clozapine pharmacotherapy in patients with schizophrenia and demonstrates the value of diagnosis using non-invasive CMR. Additional studies are needed to understand the mechanism of clozapine-induced myocarditis and how clozapine titration may affect risk.
While massive transfusion protocols (MTP) are associated with decreased mortality in adult trauma patients, there is limited research on the impact of MTP on pediatric trauma patients. The purpose of this study was to compare pediatric trauma patients requiring massive transfusion to all other pediatric trauma patients to identify triggers for MTP activation in injured children.

Using our level I trauma center's registry, we retrospectively identified all pediatric trauma patients from January 2015 to January 2018. Massive transfusion (MT) was defined as infusion of 40 mL/kg of blood products in the first 24 hours of admission. Patients missing prehospital vital sign data were excluded from the study. We retrospectively collected data including demographics, blood utilization, variable outcome data, prehospital vital signs, prehospital transport times, and injury severity scores (ISS). Statistical significance was determined using Mann-Whitney U test and chi-square test. P values less than 0.05 were consir shock indexes and lower pulse pressures. We found that shock index and systolic blood pressure are highly specific tools with promising likelihood ratios that could be used to identify patients requiring early transfusion.

Uncontrolled truncal hemorrhage remains the most common cause of potentially preventable death after injury. The notion of earlier hemorrhage control and blood product resuscitation is therefore attractive. Some systems have successfully implemented prehospital advanced resuscitative care (ARC) teams. Early identification of patients is key and is reliant on rapid decision-making and communication. The purpose of this simulation study was to explore the feasibility of early identification of patients who might benefit from ARC in a typical U.S. setting.

We conducted a prospective observational/simulation study at a level I trauma center and two associated EMS agencies over a 9-month period. The participating EMS agencies were asked to identify actual patients who might benefit from the activation of a hypothetical trauma centerbased ARC team. This decision was then communicated in real time to the study team.

63 patients were determined to require activation. The number of activations per months ranged from 2 to 15. The highest incidence of calls occurred between 4pm to midnight. Of the 63 patients, 33 were transported to the trauma center. The most common presentation was with penetrating trauma. The median age was 27 years (IQR 24-45), 75% were male, and the median injury severity score was 11 (IQR 7-20). Based on injury patterns, treatment received, and outcomes, it was determined that 6 of 33 (18%) patients might have benefited from ARC. Three of the patients died en-route to or soon after arrival at the trauma center.

The prehospital identification of patients who might benefit from ARC is possible but faces challenges. Identifying strategies to adapt existing processes may allow better utilization of the existing infrastructure and should be a focus of future efforts.

To measure the prevalence of burnout among healthcare workers (HCWs) in primary care during the COVID-19 pandemic and to understand the association between burnout, job-person fit, and perceptions of the pandemic.

We surveyed 147 HCWs (73% response rate) in two clinics in the summer of 2020 on their burnout, job-person fit, perceptions of the pandemic, and demographic/job characteristics. selleck inhibitor Logistic regression analyses were conducted to explore relationships between these variables.

Forty-three percent of HCWs reported burnout. Lower HCW burnout was associated with better job-person fit in the areas of recognition or appreciation at work (odds ratio [OR] 0.26, 95% confidence interval [CI] 0.10-0.67) and congruent worker-organization goals and values (OR 0.30, 95% CI 0.11-0.76).

Working environments with better job-person fit may be key to reducing HCW burnout even after the current crisis.

This longitudinal study of Australian workers explores a possible causal relationship between job control and general health.

Our sample included 105,017 observations (18,574 persons) over 13 annual waves from working age participants with information on job control, general health, and other sociodemographic and health factors. Three complementary longitudinal modelling approaches were used to explore the causal relationship.

There was a strong stepwise, mostly exposure to outcome, relationship between increasing job control and general health. Cumulative exposure to low job control resulted in increasingly worse general health. Taken together, these findings provide good evidence of a causal relationship between low job control and general health.

This analysis with improved causal inference over previous research showed that change in job control is strongly associated with change in general health.

The goal of this effort to investigate if experienced breachers, professionals with a career history of exposure to repeated low-level blasts, exhibited postural instability.

Postural data were examined using traditional tests of means and compared to normative data.

Breachers had significantly lower NeuroCom Sensory Organization Test (SOT) visual scores (within normative limits), prolonged Limits of Stability (LOS) test reaction time (30% of breachers and 7% of controls testing abnormal), and slower LOS movement velocity (21% of breachers and 0% of controls testing abnormal) compared to controls.

Our LOS test findings are like those previously reported for students in the military breacher training course and seem to indicate that while acute effects of blasts on sensory control of balance fade away, effects on postural LOS persist over time.

Railway accidents and suicides can have severe psychological consequences for train drivers. This study evaluates the implementation of railway critical incident management and support protocols (CIMSP) by employers. It also identifies environmental factors, characteristics of critical incidents and types of work relations affecting implementation.

A longitudinal study was conducted with 74 train drivers. Participants were interviewed one week, one, three and six months after a critical incident. Correlational analyses were performed to identify factors associated with implementation and satisfaction.

CIMSP are generally partially applied by employers when a railway incident occurs. Workers' satisfaction toward implementation of the protocol is moderate. Obstacles to implementation are geographic isolation, severity of the incident and poor quality of work relations.

These obstacles should be addressed in CIMSP design and implementation strategies.

This study aims to analyse factors that influence return to work (RTW) among workers on sickness absence due to mental disorders.

A longitudinal study conducted between 2014-2017 in São Paulo, Brazil. The 385 participants answered a questionnaire including sociodemographics, habits/lifestyle, job characteristics and clinical information. Survival analysis were performed to identify factors influencing the RTW.

Most of participants were females (74.5%), worked in jobs dealing with public (44.2%) and were depressed (52.4%). RTW occurred for 68.3% participants over 1-year follow-up. Mean duration of absence was 163.83 days. The risk profile for remaining absent was heavy smokers, be abstainer, obese, deal with the public, perceived great effort at work and low self-efficacy.

These findings can contribute in discussion about disability prevention and interventions to assure mental health care for workers.
