Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been detected in domestic and wild cats. However, little is known about natural viral infections of domestic cats, although their importance for modelling disease spread, informing strategies for managing positive human-animal relationships and disease prevention. Here, we describe the SARS-CoV-2 infection in a household of two human adults and sibling cats (one male and two females) using real-time RT-PCR, an ELISA test, viral sequencing, and virus isolation. On May 5th, 2020, the cat-owners tested positive for SARS-CoV-2. Two days later, the male cat showed mild respiratory symptoms and tested positive. Four days after the male cat, the two female cats became positive, asymptomatically. Also, one human and one cat showed antibodies against SARS-CoV-2. All cats excreted detectable SARS-CoV-2 RNA for a shorter duration than humans and viral sequences analysis confirmed human-to-cat transmission. We could not determine if cat-to-cat transmission also occurred.

Numerous studies have found associations when change scores are regressed onto initial impairments in people with stroke (slopes ≈ 0.7). However, there are important statistical considerations that limit the conclusions we can draw about recovery from these studies.

To provide an accessible checklist of conceptual and analytical issues on longitudinal measures of stroke recovery. Proportional recovery is an illustrative example, but these considerations apply broadly to studies of change over time.

Using a pooled data set of n = 373 Fugl-Meyer Assessment upper extremity scores, we ran simulations to illustrate 3 considerations (1) how change scores can be problematic in this context; (2) how "nil" and nonzero null-hypothesis significance tests can be used; and (3) how scale boundaries can create the illusion of proportionality, whereas other analytical procedures (eg, post hoc classifications) can augment this problem.

Our simulations highlight several limitations of common methods for analyzing recovsider the influence of these factors on how we measure, analyze, and conceptualize recovery.

Transcranial direct current stimulation (tDCS), in conjunction with language therapy, improves language therapy outcomes in primary progressive aphasia (PPA). However, no studies show whether white matter integrity predicts language therapy or tDCS effects in PPA.

We aimed to determine whether white matter integrity, measured by diffusion tensor imaging (DTI), predicts written naming/spelling language therapy effects (letter accuracy on trained and untrained words) with and without tDCS over the left inferior frontal gyrus (IFG) in PPA.

Thirty-nine participants with PPA were randomly assigned to tDCS or sham condition, coupled with language therapy for 15 daily sessions. White matter integrity was measured by mean diffusivity (MD) and fractional anisotropy (FA) in DTI scans before therapy. Written naming outcomes were evaluated before, immediately after, 2 weeks, and 2 months posttherapy. To assess tDCS treatment effect, we used a mixed-effects model with treatment evaluation and time interaction. We considered a forward model selection approach to identify brain regions/fasciculi of which white matter integrity can predict improvement in performance of word naming.

Both sham and tDCS groups significantly improved in trained items immediately after and at 2 months posttherapy. Improvement in the tDCS group was greater and generalized to untrained words. White matter integrity of ventral language pathways predicted tDCS effects in trained items whereas white matter integrity of dorsal language pathways predicted tDCS effects in untrained items.

White matter integrity influences both language therapy and tDCS effects. Thus, it holds promise as a biomarker for deciding which patients will benefit from language therapy and tDCS.

Stroke is a leading cause of disability worldwide. Focused training of the impaired limb has been shown to improve its functional outcome in animal models. However, most human stroke survivors exhibit persistent motor deficits, likely due to differences in rehabilitation intensity between experimental (animal) and clinical (human) settings.

The current study investigated the effect of training intensity on behavioral outcome in a mouse model of stroke.

Mice were trained preoperatively on a skilled reaching task. After training, mice received a unilateral photothrombotic stroke. Postoperatively, animals received either daily rehabilitative training (traditional intensity), intermittent rehabilitative training (every other day), or no rehabilitative training (control). Assessment of the impaired limb occurred after 14 training sessions (14 days for the Traditional group; 28 days for the Intermittent group).

Assessment of the impaired limb illustrated that traditional, daily training resulted in significten unavailable for human stroke survivors, is necessary to achieve an optimal functional outcome. The lower bounds of training intensity for functional benefit still need to be determined.Physical inactivity is prevalent among ethnic minority women including Korean American (KA) women. We explored the barriers to and facilitators of physical activity (PA) and strategies to promote continued engagement in a PA program with a component of an online community. We conducted a qualitative descriptive study of 37 KA middle-aged women who used to be physically inactive and participated in an exit interview following postintervention visit. Using a thematic analysis approach to analyze the data, we found the individual, interpersonal, and neighborhood/community-level barriers to and facilitators of PA; social influence and social support-related themes were evident. Participants expressed benefit and interest in lifestyle modification using social media. check details Such program that reduces the barriers and reinforces the facilitators may be able to help motivate KA women to increase their PA.
