This study examined the Childhelp Speak Up Be Safe (CHSUBS) child abuse prevention curriculum for high school students and addressed a gap in evidence-based child maltreatment prevention programs. CHSUBS is grounded in theory and was developed to 1) provide students with the skills they need to prevent or interrupt child abuse, bullying, and neglect, and 2) increase student knowledge about safety related to abuse. Utilizing a cluster-randomized controlled trial design, the three high schools were randomly assigned to participate in the CHSUBS curriculum or the control group. Survey items measured the efficacy of the curriculum in grades 9 through 12. https://www.selleckchem.com/products/dc661.html Surveys were implemented at baseline, immediately after the intervention, and after 6 months for a follow-up. Analyses included exploratory factor analyses and a paired samples test to determine whether increases in child maltreatment knowledge and resistance skills were gained. Findings showed positive significant results that child maltreatment knowledge and resistance skills were significantly different from pre to post for the CHSUBS group and showed no significant control group changes. High school students in the CHSUBS group appeared to gain both child maltreatment knowledge and resistance skills. Future studies on prevention programming for high school students might show results that lead to a reduction in child maltreatment and an increase in better health outcomes for adolescents.

Emerging studies suggest that some patients may experience uncommon complications, such as thrombotic or hemorrhagic episodes. Here we present a 59-year-old male patient who had a hemorrhage episode from a branch of the pulmonary arteries and was treated by interventional embolization. Our case report demonstrates the importance of early diagnosis of hemorrhagic complications of COVID-19 and the possible benefits of early vascular intervention.The SARS-CoV-2 infection has been predominately associated with lung disease. However, emerging evidence has associated the COVID-19 infection with a hypercoagulable state. This hypercoagulable state can occur despite the use of anticoagulants and antiplatelets. In fact, it may even be the presenting symptom of COVID-19 in some patients. Thromboembolism associated with COVID-19 carries a worse prognosis and should be identified as early as possible. Therefore, we report 2 patients with arterial thrombosis in the form of limb ischemia in the setting of COVID-19.The request for CT (computed tomography) diagnostic in patients with suspected COVID-19 pneumonia has become part of the daily clinical routine. We reported a case of a 61-year-old patient with flu-like symptoms and a suspected COVID-19 pneumonia. After a negative PCR-test (polymerase chain reaction), a non-contrast enhanced CT was performed which revealed a suspicious hyperdensity in the left pulmonary artery and a pneumonia in the left lower lobe. A contrast enhanced CT confirmed a pulmonary embolism. An acute pulmonary embolism is a major complication and a main differential diagnosis of COVID-19. A hyperdense pulmonary artery sign (PAS) is a sensitive sign for a pulmonary embolism. Non-enhanced chest CT scans should be checked for hyperdense PAS in suspected of COVID-19 patients.Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused the ongoing global pandemic. It can manifest a wide range of complications depending upon the severity of infection and comorbidities of the patient. Vaccines are very important measure to provide protection against COVID-19. We report a case of 72-year-old female with past medical history of hypertension and diabetes mellitus who underwent imaging with positron emission tomography (PET) scan imaging for staging of her small cell urinary bladder cancer and was found to have hypermetabolic uptake in the deltoid muscle of the left shoulder and hypermetabolic left axillary and pectoral lymph nodes due to mRNA BNT-162b2 (Pfizer-BioNTech COVID-19 vaccine) vaccine administrated 3 days ago prior to PET scan. To explore the relationships of procollagen type 1 N-terminal propeptide (P1NP) and cross-linked C-telopeptide of type 1 collagen ( -CTX) with bone mineral density (BMD) in postmenopausal women. All postmenopausal women were selected from a community-based case-control study. The anteroposterior L1-L4 and left proximal femur BMD were measured. P1NP and -CTX were also collected and tested. The main correlation analysis was applied to explore the relationships of BMD, P1NP, and -CTX. The total 1055 postmenopausal women were enrolled. The BMD at all sites kept a decrease continually with age ( < 0.01). In addition, the level of -CTX increased significantly from 45 to 50 years old and remained at a high level in the later stage, while the level of P1NP changed little or even decreased with age. Logistic regression model showed that -CTX has better ability to predict BMD than P1NP, as demonstrated by an area under the curve (AUC) of 0.63. P1NP and -CTX are important markers to monitor bone metabolism. This trial is registered with ChiCTR-SOC-17013090. The date of registration is Oct. 23, 2017. P1NP and β-CTX are important markers to monitor bone metabolism. This trial is registered with ChiCTR-SOC-17013090. The date of registration is Oct. 23, 2017. Progranulin (PGRN) and its potential receptor Eph-receptor tyrosine kinase-type A2 (EphA2) are inflammation-related molecules that present on the atherosclerotic plaques. However, the roles of circulating PGRN and EphA2 in coronary artery disease (CAD) remain unclear. To study the clinical significance of circulating PGRN and EphA2 levels in Chinese patients undergoing coronary angiography. Levels of circulating EphA2 fragments and PGRN were examined in 201 consecutive individuals who underwent coronary angiography for suspected CAD in our center from Jan 2020 to Oct 2020. Demographic characteristics, results of biochemical and auxiliary examinations, and other relevant information were collected. The coronary atheroma burden was quantified by the Gensini score and the existence of chronic total occlusion (CTO). Univariate analysis and multivariate logistic regression analysis were used to analyze the risk factors for acute coronary syndrome (ACS). In patients with ACS and SAP, a receiver operating characteristic (ROC) curve was generated to detect the accuracy and discriminative ability of levels of EphA2 and PGRN, the Gensini score, and cardiac injury biomarkers as surrogate endpoints for CTO.
