Hand dexterity dysfunction is a key feature of disability in people with progressive multiple sclerosis (PMS). It underlies corticospinal tract (CST) and cerebellar integrity, as well as disruption of cortical networks, which are hardly assessed by standard techniques. Transcranial magnetic stimulation is a promising tool for evaluating the integrity of intracortical motor pathways.
To investigate neurophysiological correlates of motor hand impairment in PMS.
Antero-posterior (AP) stimulation of the primary motor cortex activates the CST indirectly through polysynaptic pathways, while a direct CST activation occurs with latero-medial (LM) directed current. UNC0379 Thirty PMS and 15 healthy controls underwent dominant hand motor evoked potentials (MEP) using AP and LM-directed stimulation, and a clinical assessment of dexterity (nine-hole peg test) and strength (MRC scale, grip and pinch).
PMS with AP-LM latency difference 2.5 standard deviation above the mean of controls (33%) showed worse dexterity but no difference in upper limb strength. Accordingly, AP-LM latency shortening predicted dexterity (R
 = 0.538,
 < 0.001), but not strength impairment. On the contrary, absolute MEP latencies only correlated with strength (grip R
 = 0.381,
 = 0.014; MRC R
 = 0.184,
 = 0.041).
AP-LM latency shortening may be used to assess the integrity polysynaptic intracortical networks implicated in dexterity impairment.

Many older adults receive help from both family caregivers and home care workers. We aimed to understand family caregivers' perspectives on home care workers.
This qualitative study took place at an academic medical center in New York, N.Y. We interviewed family caregivers of community-dwelling older adults about their experiences with home care workers. We analyzed transcripts thematically.
We interviewed 17 family caregivers and identified four major themes (a) home care workers provide functional and emotional support; (b) home care is logistically challenging; (c) finding the right fit between home care workers, older adults, and families is essential; and (d) home care workers and family caregivers coordinate care well beyond the initiation of home care.
Despite its logistical challenges, home care benefits patients and family caregivers. Given the growing prevalence of caregiving, clinicians and family caregivers might benefit from training and support about working with home care workers.

It can be challenging to recognize undifferentiated/immature ganglion cells, especially single forms. Ganglion cells and glia are derived from enteric neural crest cells (ENCCs), a group of autonomic nervous system (ANS)-lineage neural crest progenitors that
regulates. Phox2b is an excellent marker for neoplastic and non-neoplastic ANS cells (eg, peripheral neuroblastic tumors [pNTs]). We hypothesized that Phox2b immunohistochemical staining (IHC) would also be useful for detecting ENCCs.
Hematoxylin and eosin, calretinin IHC, and Phox2b IHC were reviewed on 21 pull-through specimens and on a cohort of 12 rectal biopsies.
Phox2b IHC demonstrated nuclear positivity in all of the ganglion cells across the different phases of differentiation without background staining. The Phox2b result correlated with the morphological findings, calretinin IHC results, and diagnoses based on the routine diagnostic method. The intensity was uniformly strong in the undifferentiated/immature forms and became variable in the mature forms; this pattern was similar to that seen in pNTs.
Phox2b IHC was highly sensitive and specific for detecting ganglion cells. It worked especially well for immature ganglion cells, seen in premature neonates, and scattered single forms in transition zones. In basic research settings, Phox2b can be a useful marker for early differentiation of ENCCs.

Porphyrins and other tetrapyrrolic molecules possess unique magnetic, optical and other photophysical properties that make them useful for bioimaging and therapy. This review touches briefly on some of the synthetic strategies to obtain porphyrin- and tetrapyrrole-based nanoparticles, as well as the variety of applications in which crosslinked, self-assembled, porphyrin-coated and other nanoparticles are utilized. We explore examples of these nanoparticles' applications in photothermal therapy, drug delivery, photodynamic therapy, stimuli response, fluorescence imaging, photoacoustic imaging, magnetic resonance imaging, computed tomography and positron emission tomography. We anticipate that this review will provide a comprehensive summary of pyrrole-derived nanoparticles and provide a guideline for their further development.
Fingolimod (FTY) is an effective second-line drug for relapsing-remitting multiple sclerosis, with ~50% patients showing no evidence of disease activity (NEDA) after 2 years. Nonetheless, the early identification of non-responders is extremely important, to promptly address them to more aggressive drugs.
This cohort study evaluates FTY medium-term effectiveness, searching for early markers of treatment failure.
Three hundred eighty patients starting FTY were enrolled and classified according to NEDA and time to first relapse criteria at 4-year follow-up. Logistic and Cox regression analyses were applied to identify early predictors of non-response.
At 4 years, 65.6% of patients were free from relapses and 35.4% had NEDA. Female gender was associated with a higher risk of non-response. Moreover, evidence of clinical and/or magnetic resonance imaging (MRI) activity during the first year of treatment was highly predictive of disease activity in the follow-up the positive predictive value for non-response was 0.
