Altered cerebral perfusion has been reported in obstructive sleep apnea (OSA). Using dynamic susceptibility contrast MRI, we compared cerebral perfusion between male OSA patients and male healthy reference subjects and assessed correlations of perfusion abnormalities of OSA patients with sleep parameters and neuropsychological deficits at 3 T MRI, polysomnography and neuropsychological tests in 68 patients with OSA and 21 reference subjects. We found lower global and regional cerebral blood flow and cerebral blood volume, localized mainly in bilateral parietal and prefrontal cortices, as well as multiple focal cortical and deep structures related to the default mode network and attention network. In the correlation analysis between regional hypoperfusion and parameters of polysomnography, different patterns of regional hypoperfusion were distinctively associated with parameters of intermittent hypoxia and sleep fragmentation, which involved mainly parietal and orbitofrontal cortices, respectively. There was no association between brain perfusion and cognition in OSA patients in areas where significant association was observed in reference subjects, largely overlapping with nodes of the default mode network and attention network. Our results suggest that impaired cerebral perfusion in important areas of functional networks could be an important pathomechanism of neurocognitive deficits in OSA.Rural Health Clinics (RHCs) were created in 1977 to address the high health care needs, limited provider access, and poor health outcomes of rural Americans. click here Although innovative at their inception, the provider-centric model of RHC cost-based reimbursement structures has not evolved, leaving limited opportunities for change; many have failed. Comprehensive, proactive change is needed. Registered nurses (RNs) working at the top of their practice scope are a neglected clinical resource that can improve access, quality, value, and satisfaction for rural patient communities. RHC reimbursement policy must evolve to sustain and support this significant RN role. RNs have demonstrated value in care continuity and disease management, but there is little research on the utilization of RNs using their enhanced skill set in RHCs. Using the Bardach and Patashnik's eight steps of policy analysis, the authors will describe the background and regulations of RHCs, identify current barriers to improving the health of America's rural residents, and then provide evidence to support a new policy option according to the Quadruple Aim framework. The result is a sustainable policy recommendation designed to best serve rural communities.Increasing use of evidence-based interventions (EBIs) in local settings will help reduce the research-practice gap and improve health equity. Because adaptation to new settings and populations is essential to effective EBI use, frameworks to guide practice are receiving more attention; most, however, only provide broad guidelines without instructions for making adaptations in practice. Therefore, practitioners may need additional training or technical assistance (TA) to implement and adapt EBIs. This study explores whether practitioners' and students' general EBI training or TA and level of adaptation experience are associated with self-efficacy in adapting EBIs and with attitudes toward EBI use. We analyzed baseline survey data of participants in an evaluation of IM-Adapt Online, a newly developed decision support tool. We asked about previous training on EBIs, general and specific adaptation behaviors, and attitudes toward EBIs and found an association between previous training or TA in using EBIs with higher self-efficacy for using and adapting EBIs. Respondents with prior EBI training were significantly more likely to have higher self-efficacy in EBI behaviors across subdomains and in total than those without training. Respondents reported lowest self-efficacy for planning adaptations (M = 3.35) and assessing fit of EBIs to their local context (M = 3.41). This study suggests the importance of EBI adaptation training and TA to increase adoption and adaptation of EBIs, subsequently. More adaptation-specific training is warranted to assist students, practitioners, and researchers undertaking the adaptation process and implement EBIs. Future training on EBI adaptation can help practitioners tailor EBIs to meet the specific needs of their populations.

Invasive mold infections contribute to morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplantation. The optimal strategy for primary antifungal prophylaxis in this patient population remains uncertain.

Medical records of patients who underwent allogeneic hematopoietic stem cell transplantation between 1 January 2013 and 31 December 2017 were retrospectively reviewed. Adult patients were included if they received micafungin followed by fluconazole, with the option to escalate to voriconazole, for antifungal prophylaxis. The primary outcome was the incidence rate of proven or probable invasive mold infection. Secondary outcomes were time to invasive mold infection diagnosis, invasive mold infection-related mortality, and risk factors associated with invasive mold infection.

Two hundred patients were included in the study, a majority of whom underwent matched unrelated (46%) or matched related (33%) donor transplants. The incidence rate of proven or probable invasive mort of allogeneic hematopoietic stem cell transplantation recipients, the incidence of proven or probable invasive mold infection was higher than expected based on previous literature. In the absence of standard guidance on anti-mold prophylaxis in this patient population and given that unique risk factors for invasive mold infection may differ between institutions, it is essential that centers performing allogeneic hematopoietic stem cell transplantation routinely monitor their antifungal prophylaxis strategies for effectiveness.Regenerative engineering has pioneered several novel biomaterials to treat critical-sized bone injuries. However, despite significant improvement in synthetic materials research, some limitations still exist. The constraints correlated with the current grafting methods signify a treatment paradigm shift to osteoinductive regenerative engineering approaches. Because of their intrinsic potential, inductive biomaterials may represent alternative approaches to treating critical bone injuries. Osteoinductive scaffolds stimulate stem cell differentiation into the osteoblastic lineage, enhancing bone regeneration. Inductive biomaterials comprise polymers, calcium phosphate ceramics, metals, and graphene family materials. This review will assess the cellular behavior toward properties of inductive materials.
