For decades, neurologists have been advocating that anyone with acute focal deficits report immediately to the closest hospital’s emergency room. Major advancements in the hyperacute diagnosis and treatment of stroke have justified our call-to-action slogan of “Time is Brain”-faster therapy leads to superior outcomes. However, this mantra has been recently usurped by the catchphrase “Stay at Home” during the coronavirus disease 2019 (COVID-19) pandemic. Fewer patients are presenting to hospitals with acute stroke; our census is down. Presumably the etiology of this phenomenon is either strict “social distancing” that some people may misperceive to exclude even emergent situations, or fears of contracting the virus while hospitalized. In this Short Report, we describe the year-over-year drop in stroke volume (ischemic and hemorrhagic both) coinciding with a paradoxical rise in acute reperfusion therapies at our university hospital. These data imply that stroke patients with mild/moderate symptoms are most likely staying home, and not receiving urgent therapies, and correspondingly, only the most severely disabled stroke patients are ultimately seeking and receiving help. We must remind our patients and the general public that our services are essential and available, as stroke still remains a medical emergency, and carries a likely higher overall mortality risk than COVID-19. As neurologists, we also must be vigilant for the atypical presentations and varied etiologies of stroke associated with COVID-19 as well.We used cathodoluminescence (CL) spectroscopy to characterize the oxygen vacancies (VO) in ceria (CeO2). The effects of the processing atmosphere and thermal quenching temperature on the nature and distribution of the intrinsic defects and on the spectroscopic behavior were investigated. The presence of polarons and associates of the polarons with the oxygen vacancies such as (VO••-CeCe’)• is demonstrated. CL intensity quenching above a critical concentration of VO has been shown. Even though the emission centers in all samples are the same, their concentration changes with the oxygen partial pressure of the processing atmosphere. Deconvolution of the observed CL spectra shows that the emissions originating from the F0 centers prevail over those of F+ centers of VO when the defect concentration is high.

Individuals who have colorectal or endometrial cancers displaying loss of immunohistochemical staining of one or more mismatch repair proteins without an identifiable causative germline pathogenic variant have unexplained mismatch repair deficiency (UMMRD). Comprehensive germline genetic testing for Lynch syndrome (LS) includes sequencing and deletion/duplication analysis of

and

, deletion analysis of

, and

inversion analysis. Updated genetic testing to include elements of comprehensive LS testing not previously completed could further clarify LS status in individuals with UMMRD, allowing for tailored screening guidelines for affected individuals and their family members. However, patient understanding of the potential impact of updated genetic testing for LS is unclear. This study aimed to evaluate the interest in and perceived impact of updated genetic testing among individuals with UMMRD at a tertiary academic center.

Hair follicle (HF) formation and growth are sustained by epithelial-mesenchymal interaction via growth factors and cytokines. Pivotal roles of FGFs on HF regeneration and neogenesis have been reported mainly in rodent models. FGF expression is regulated by upstream pathways, represented by canonical WNT signaling; however, how FGFs influence on human folliculogenesis remains elusive. The aim of this study is to assess if human scalp-derived fibroblasts (sFBs) are able to modulate their FGF expression profile in response to WNT activation and to evaluate the influence of WNT-activated or suppressed FGFs on folliculogenesis.

Dermal papilla cells (DPCs), dermal sheath cells (DSCs), and sFBs were isolated from the human scalp and cultured independently. The gene expression profile of FGFs in DPCs, DSCs, and sFBs and the influence of WNT activator, CHIR99021, on FGF expression pattern in sFBs were evaluated by reverse transcription polymerase chain reaction, which were confirmed at protein level by western bloFGF9 increased both the number and the diameter of newly formed HFs, while FGF7 decreased HF diameter.

The results implied that sFBs support HF formation by modulating regional FGF expression profile responding to WNT activation.

Evidence suggests that targeted exercise is important for people living with dementia. The aim of this review was to collect and synthesize evidence on the known barriers and facilitators to adherence to walking group exercise of older people living with dementia in the community.

We have searched appropriate electronic databases between January 1990 until September 2019, in any language. Additionally, we searched trial registries (clinicaltrial.gov and WHO ICTRP) for ongoing studies. We included all study designs. Studies were excluded when participants were either healthy older people or people suffering from dementia but living in residential care. Narrative synthesis was used.

10 papers met the inclusion criteria. The narrative analysis focused on barriers, facilitators, and adherence. All studies reported on barriers and facilitators. Barriers included bio-medical reasons (including mental wellbeing and physical ability); relationship dynamics; and socio-economic reasons and environmental issues. see more Fained instructors or healthcare professionals are recommended as group exercise leaders.

This systematic review of literature has highlighted known barriers and facilitators to adherence to walking groups type of exercise for people living with dementia in community. Carers’ willingness to engage, their circumstances, perspectives and previous experiences of exercise seem to play a key role in facilitating adherence but there is little research that explores these. Also, the design, location and organisation of walking groups facilitate adherence. This reflects the need for such activities to be part of a wider ‘program of care’, tailored to the needs of the individual, flexible and convenient. Knowledgeable and well-trained instructors or healthcare professionals are recommended as group exercise leaders.
