The most complicated problem in detecting workplace hazards is the dynamic condition of industrial settings and the unpredictability of workers' behavior. A newly developed method focusing on cognitive differences between individuals is required to evaluate unsafe behaviors of workers. This study aimed at development and validation of a new questionnaire for measuring cognitive unsafe behaviors of front-line industrial workers. A new questionnaire with 61 items was developed and the main measurement characteristics (validity and reliability) were analyzed. Content validity analysis showed that 61 items had an excellent content validity index (<0.78) and content validity ratio (>0.42). Good internal consistency (Cronbach's = 0.95) and stability (intra-class correlation coefficient = 0.98) were found for the new instrument. The result of confirmatory factor analysis indicated that the selected model was satisfactory. The new instrument appears to be a valid and reliable tool to assess cognitive unsafe behaviors of front-line industrial workers.

Time-dependent fear memory generalization triggered by phosphodiesterase 5 inhibition during reconsolidation.

Fear generalization, a lack of discrimination between safe and unsafe cues, is a hallmark of posttraumatic stress disorder. The phosphodiesterase 5 (PDE5) regulates the cyclic guanosine monophosphate (cGMP) pathway, which has been proposed to be involved in fear memory generalization. However, whether PDE5 activity underlies fear memory generalization remains unexplored.

Cumulative Dispensing of Oral Corticosteroids Over 12 Months in People with COPD.
Int J Chron Obstruct Pulmon Dis

School of Translational Medicine, Monash University, Melbourne, VIC, Australia.
Purpose: Oral corticosteroids (OCS) are recommended for the treatment of exacerbations in people with COPD; however, high cumulative lifetime doses (≥1000mg prednisolone-equivalent) are associated with adverse health effects. This issue is well defined in asthma but is less well understood in COPD. The aim of this study was to examine cumulative OCS dispensed to people with COPD over 12 months.

Department of Environment and Public Health, University of Environment and Sustainable Development, Somanya, Ghana.
Background: Good knowledge about the ovulatory cycle plays an important role in reducing unwanted pregnancies and unsafe abortions among adolescent females. However, in Ghana, knowledge of the ovulatory cycle among adolescent females is not well studied. Thus, this study sought to assess adolescent females' knowledge regarding the ovulatory cycle and its determinants in Ghana.

Background: Telehealth involves providing health care remotely using communication tools such as telephone, video, and remote patient monitoring. Research on telehealth has shown many benefits, including improved access to care and reduced costs, and drawbacks, including delays in care, breakdowns in communication, and missed diagnoses. The use of telehealth nationally, including in the Veterans Health Administration (VHA), expanded dramatically during the COVID-19 pandemic.
