Pelvic osteotomies with regard to acetabular dysplasia: Are there benefits, survivorship and also complications distinctions involving different osteotomy methods?
Heterotopic ossification (HO) is characterized by the abnormal growth of ectopic bone in soft tissues, frequently occurring within the military population because of extensive orthopaedic combat trauma. Tacrine MicroRNAs (miRNAs) are small noncoding RNAs that act as post-transcriptional regulators of gene expression. We hypothesized that a clinically relevant miRNA signature could be detected in patients following injury that progressed to form HO (HO+) or did not form HO (HO-).

Tissue samples were obtained from injured servicemembers during their initial surgical debridements, and miRNA profiling was performed using a real-time miRNA polymerase chain reaction (PCR) array. Primary mesenchymal progenitor cells (MPCs) were harvested from debrided traumatized human muscle tissue, and cells were isolated and cultured in vitro. Mimic miRNAs were transfected into MPCs, followed by downstream in vitro analyses.

The investigation of the miRNA expression profile in the tissue of HO+ compared with HO- patients demonstrated a molecular signature that included the upregulation of miR-1, miR-133a, miR-133b, miR-206, miR-26a, and miR-125b. Transfection of each of these mature miRNAs into MPCs followed by osteogenic induction demonstrated that miR-1, miR-133a, miR-133b, and miR-206 enhanced osteogenic differentiation compared with control treatments. In silico and in vitro analyses identified the transcription factor SOX9 as a candidate downstream target of miR-1 and miR-206 miRNAs.

Our data demonstrated a molecular signature of miRNAs in the soft tissue of wounded servicemembers that was associated with the development of HO, providing novel insights into the underlying molecular mechanisms associated with posttraumatic HO.

Businesses are struggling to re-open as the world continues to deal with the coronavirus 2019 (COVID-19) pandemic. The reopening of businesses will require employers to implement safe return-to-work strategies through evaluation, testing, work modifications, and development of appropriate workplace policies. There will be unique challenges along the way as no one approach will be ideal for all workplaces and industries. This document is intended to provide return-to-work guidance for both employers and the occupational and environmental medicine physicians who will be supporting businesses in implementing safe return-to-work strategies.
We study employee perspectives on return to physical workspaces to ultimately inform employers' and policy makers' decision making around the return to work during COVID-19.

We tested the three-component conceptual model using survey data collected in the United States in May 2020 from samples of energy workers (N = 333).

Women, non-Caucasians, and employees living in multi-generational households were less willing to return. Concerns about childcare were negatively related to willingness to return, whereas organizational strategies for mitigating COVID-19 transmission at work were positively related to willingness to return. COVID-19 infections in an employees' network were also negatively related to employees' willingness to return.

Blanket policies may miss the nuanced needs of different employee groups. Employers and policy makers should adopt flexible approaches to ensure a return to workspaces that addresses employee concerns and needs.

To identify early symptoms allowing rapid appraisal of infection with SARS-CoV-2 among healthcare workers of a large Belgian hospital.

Healthcare workers with mild symptoms of an acute respiratory tract infection were systematically screened on clinical characteristics of corona virus disease 2019 (COVID-19). A nasopharyngeal swab was taken and analyzed by real-time Reverse-Transcription-Polymerase-Chain-Reaction (rRT-PCR).

Fifty percent of 373 workers tested COVID-19 positive. The symptoms cough (82%), headache (78%), myalgia (70%), loss of smell or taste (40%), and fever more than or equal to 37.5 °C (76%) were significantly higher among those infected.

Where each individual symptom contributes to the clinical evaluation of possible infection, it is the combination of COVID-19 symptoms that could allow for a rapid diagnostic appraisal of the disease in a high prevalence setting. Early transmission control is important at the onset of an epidemic.

Certified nursing assistants (CNAs) are low-wage healthcare workers who provide direct care to nursing home residents, yet also experience significant health disparities. However, limited research has been conducted on CNAs' perceived barriers and facilitators to workplace health promotion (WHP) participation.

Informed by the Consolidated Framework for Implementation Research (CFIR), 24 CNA semi-structured, in-depth interviews were conducted in two Chicagoland nursing homes.

Key barriers were time-constraints and lack of staffing, lack of access to WHP programs, and limited organizational and employer support. Facilitators included the availability of WHP programs, breaks, and other workplace benefits, and enhanced leadership and familial support.

An effective WHP program must attempt to minimize the work-related, organizational, and environmental barriers while supporting high motivation of CNAs in health promotion. We offer some suggestions for enhancing CNAs' WHP access and utilization.
