To identify if e-cigarette usage is an on-campus problem for secondary schools and evaluate initial school survey responses. selleck More specifically, this survey can aid in identifying where students are seen using e-cigarettes, if smoke alarms have been newly inserted on school property, if smoke alarms have been tampered with to allow for vaping without detection; and, if any e-cigarette fires or explosions have occurred on school property.

This survey, disseminated to New Jersey secondary school teachers across seven sessions January-July 2019, resulted in 104 complete responses of 109 respondents. The survey was conducted after fire prevention, exit/egress, and life safety portions of “OSHA 10 Plus for General Industry” courses. Survey questions included number of times teachers observed students vaping and location where vaping in last 12 months, fire alarm installation and tampering, and fires or explosions and injuries from vaping/e-cigarette devices.

Many (63%) respondents reported very or moderately common rates of vaping within their schools; however, three of four questions regarding school fire and smoke alarm use specifically to detect vaping had a majority of unsure/I don’t know responses.

Results suggested concerns regarding student vaping and e-cigarette use inside and outside secondary schools. Improved school detection and response are warranted.

Coronavirus disease 2019 (COVID-19) pandemic has caused serious psychological problems, including panic attack, anxiety, stress, and depression. The main objective of this study was to measure the prevalence and compare the severity of this psychological distress among four groups of an Iranian population.

In a cross-sectional survey, the mental health status of four groups of an Iranian society including community population, patients with COVID-19, medical staff, and medical students were investigated by the self-report questionnaire of Depression, Anxiety, and Stress Scale (DASS). DASS-21 questionnaire and the demographic data sheet were filled out by the participants. All statistical analyses were done using R version 3.6.1 software. P-values less than 0.05 were considered as statistically significant. ANOVA test was used to compare the severity of stress, anxiety, and depression between the four study groups.

Of the 886 participants in this survey, 554 (62.5%) were men and 332 (37.5%) were women, a professional medical staff and community population. Continuous surveillance and monitoring of psychological distress for outbreaks should become a routine part of preparedness efforts worldwide.

COVID-19 patients and medical students in contact with these patients were at a high risk for mental illness due to lower experience compared with professional medical staff and community population. Continuous surveillance and monitoring of psychological distress for outbreaks should become a routine part of preparedness efforts worldwide.

Osteoporosis is a metabolic bone disorder characterized by deterioration in the quantity and quality of bone tissue, with a consequent increase susceptibility to fracture.

In this study, we sought to determine the efficacy of platelet-rich fibrin releasates (PRFr) in augmenting the therapeutic effects of stem cell-based therapy in treating osteoporotic bone disorder. An osteoporosis mouse model was established through bilateral ovariectomy on 12-week-old female ICR (Institute of Cancer Research) mice. Eight weeks postoperatively, the ovariectomized (OVX) mice were left untreated (control) or injected with PRFr, bone marrow stem cells (BMSCs), or the combination of BMSCs and PRFr. Two different injection (single versus quadruple) dosages were tested to investigate the accumulative effects of BMSCS and PRFr on bone quality. Eight weeks after injection, the changes in tibial microstructural profiles included the percentage of bone volume versus total tissue volume (BV/TV, %), bone mineral density (BMD, g/cm3y through the increase in effect size of cells and growth factors. Our data also revealed the combination therapy of BMSCs and PRFr has better effect in enhancing osteogenesis, which may provide insight for the development of a novel therapeutic strategy in osteoporosis treatment.

The systemic administration of combined BMSCs and PRFr protected against OVX-induced bone mass loss in mice. Moreover, the improvement of bony profile scores in quadruple-injection group is better than the single-injection group, probably through the increase in effect size of cells and growth factors. Our data also revealed the combination therapy of BMSCs and PRFr has better effect in enhancing osteogenesis, which may provide insight for the development of a novel therapeutic strategy in osteoporosis treatment.

To this date little information exists on the effects, clinical course and outcome of the COVID-19 among patients undergoing transplantation.

A 35 year old male referred with loss of sense of smell and taste after having close contact with his brother who was diagnosed with COVID-19 five days prior to his symptoms. The patient had undergone liver transplantation 3 years prior to his referral due to primary sclerosing cholangitis in association with ulcerative colitis and was using immunosuppressive medications. The patient referred to a local physician with mild symptoms of fatigue, cough, myalgia, dizziness, and nausea/vomiting with a fear of contracting the disease. Except for a CRP of 32 his other blood tests were normal. After 3 days of hospital admission the patient was discharged with a good condition. His brother had developed fever, chills, headache, mild dyspnea and an objective loss of sense of smell and taste and was sent home and advised to self-quarantine. Both patients had CT scans in favor of COVID-19.

Our patient who had liver transplantation and COVID-19 did not present more severe symptoms compared to his counterpart without liver transplantation and did not need to be hospitalized or be given antiviral drugs for COVID-19.
