The Modified Oswestry Low Back Pain Disability Questionnaire (MODQ) is used for evaluating the functional disability in patients with low back pain (LBP). However, the measurement characteristics of the MODQ among Arab patients are unknown. In this study, we aimed to translate and cross-culturally adapt the MODQ into Arabic and evaluate its psychometric properties. ⋯ The Arabic version of the MODQ demonstrates adequate psychometric properties and can be used to assess disability level in patients with LBP in Arabic-speaking communities.

The origin of low frequency cerebral hemodynamic fluctuations (CHF) in the resting state remains unknown. Breath-by breath O2-CO2 exchange ratio (bER) has been reported to correlate with the cerebrovascular response to brief breath hold challenge at the frequency range of 0.008-0.03Hz in healthy adults. bER is defined as the ratio of the change in the partial pressure of oxygen (ΔPO2) to that of carbon dioxide (ΔPCO2) between end inspiration and end expiration. In this study, we aimed to investigate the contribution of respiratory gas exchange (RGE) metrics (bER, ΔPO2 and ΔPCO2) to low frequency CHF during spontaneous breathing. ⋯ Although the physiological mechanisms underlying the strong correlation between bER and CHF are unclear, our findings suggest the contribution of bER to low frequency resting state CHF, providing a novel insight of brain-body interaction via CHF and oscillations of RGE metrics.

To investigate the computed tomography (CT) characteristics and diagnostic value of novel coronavirus pneumonia (NCP or COVID-19) in pregnancy. ⋯ The CT characteristics of COVID-19 in pregnancy were mainly observed in early and progressive stages, and multiple new lesions were common. And there were consolidations of varying sizes and degrees within the lesion. Moreover, the original ground glass lesions could be fused or partially absorbed. Six patients had small bilateral pleural effusion. In summary, CT scans can play an important role in early screening, dynamic observation, and efficacy evaluation of suspected or confirmed cases of pregnant women with COVID-19.

Involving the autism community in research increases the real-world translation and impact of findings. The current study explored the research priorities of parents of school-aged children on the autism spectrum across the home, school, and community settings. ⋯ The Q-sort method highlighted different top priorities, with understanding the parent, sibling, child and family impact and stress the highest ranked priority for home, teacher/staff education and support for the school, and recognizing and supporting anxiety for the community. The implications of the findings are discussed in relation to shifting the framework of autism research to align research agendas with parental priorities.

Male veterans ages 55-74 comprise a disproportionate number of suicide deaths among United States veterans, for whom a majority of suicides are firearm-related. Little is known about the firearm-related experiences and beliefs of veterans, which could be informative for firearm-related lethal means safety interventions. The aim of this qualitative study was to identify themes relevant to developing such interventions among older male veterans. ⋯ We identified themes relevant to developing firearm-specific lethal means safety interventions among older male veterans. Findings suggest potential obstacles (e.g., sociocultural value of firearms) to affecting changes in firearm behaviors, and factors that could potentially facilitate interventions (e.g., family involvement). Consideration of these findings may be important for developing personalized, effective interventions for this population.
