To assess the prophylactic effect of anodal tDCS of the left motor cortex in patients with resistant chronic migraine (CM) and its long-term maintenance.

In a patient-assessor blinded, sham-controlled trial, 36 patients were randomized to receive anodal tDCS (active group, n=18) or sham tDCS (sham group, n=18). The studied population was characterized by a previous failure of at least 3 classes of preventive drugs and a mean duration of migraine history of 26 years. The tDCS procedure consisted of an induction phase of 5 consecutive daily sessions (week 1) followed by a maintenance phase of 1 weekly session during the next 4 weeks and two bimonthly sessions in the next month, for a total of 11 sessions during 2 months. Anodal tDCS was delivered at 2mA intensity for 20min over the left motor cortex. The primary endpoint was the reduction in the monthly number of migraine attacks from baseline to each period of follow-up (months 1, 2, 3, 5) between the active and sham groups.

The monthly number of migraine attacks expressed as the percentage of reduction from baseline was significantly reduced in the active versus the sham group, from the end of first month (-21%±22 vs.-2% ±25, p=0.019) to the end of follow-up (3-month post-treatment) (-32%±33 vs.-6% ±39, p=0.011). At this time, the rate of responders, defined as a reduction of the monthly number of migraine attacks ≥30% from baseline, was significantly higher in the active group than in the sham group (50% vs. 14%, p=0.043).

Our results show a marked prophylactic effect of anodal tDCS of the left motor cortex in resistant CM extending several months after the stimulation period, and suggest that this neuromodulatory approach may be part of the prophylactic alternatives available for CM.

Alpha oscillations have been proposed to provide phasic inhibition in the brain. Yet, pinging alpha oscillations with transcranial magnetic stimulation (TMS) to examine phase-dependent network excitability has resulted in conflicting findings. At the cellular level, such gating by the alpha oscillation remains poorly understood.

We examine how the excitability of pyramidal cells and presumed fast-spiking inhibitory interneurons depends on the phase of the alpha oscillation.

Optogenetic stimulation pulses were administered at random phases of the alpha oscillation in the posterior parietal cortex (PPC) of two adult ferrets that expressed channelrhodopsin in pyramidal cells. Post-stimulation firing probability was calculated as a function of the stimulation phase of the alpha oscillation for both verum and sham stimulation.

The excitability of pyramidal cells depended on the alpha phase, in anticorrelation with their intrinsic phase preference; pyramidal cells were more responsive to optogenetic stimulather half-cycle serves as a signal detector for unexpected input. The functional role of different parts of the alpha cycle may vary across the cortex depending on local neuronal firing properties.

This review article focuses on clinical and genetic features of paroxysmal neurological disorders featuring episodic ataxia (EA) and epilepsy and help clinicians recognize, diagnose, and treat patients with co-existing EA and epilepsy. It also provides an overview of genes and molecular mechanisms underlying these intriguing neurogenetic disorders.

Based on a literature review on Pubmed database, a list of genes linked to paroxysmal neurological disorders featuring EA and epilepsy were compiled. Online Mendelian Inheritance in Man (OMIM) was used to identify further reports relevant to each gene.

Among the various forms of EAs, only EA1 (KCNA1), EA2 (CACNA1A), EA5 (CACNB4), EA6 (SLC1A3), and EA9 (SCN2A) phenotypes with associated epilepsy have been described. Next-generation sequencing (NGS) has helped in the identification of other genes (e.g. KCNA2, ATP1A3, SLC2A1, PRRT2) which have shown an overlapping phenotype with EA and epilepsy.

Overlapping clinical features between EA and epilepsy may hinder an accurate classification, and complex genotype-phenotype correlation may often lead to misdiagnosis. NGS has increased the awareness of common genetic etiologies for these conditions. In the future, extensive genetic and phenotypic characterizations can help us to elucidate the boundaries of a wide phenotypic spectrum. These insights may help develop new precision therapies in paroxysmal neurological disorders featuring EA and epilepsy.

Current dietary guidelines recommend avoiding foods and beverages with added sugars and higher sodium before age 2 years.

The aim was to describe daily snack food intake (frequency and total energy) and the associations with overconsumed nutrients (added sugars, sodium, and saturated fats) and child weight-for-length z scores.

A cross-sectional, secondary analysis of baseline data from an ongoing longitudinal intervention was conducted.

A sample of 141 caregivers with infants (aged 9 to 11 months) and toddlers (aged 12 to 15 months) was recruited in Buffalo, NY, between 2017 and2019.

Three 24-hour dietary recalls were used to categorize 'sweet and salty snack foods' or 'commercial baby snack foods' based on the US Department of Agriculture What We Eat in America food group classifications and estimate nutrient intakes. Child recumbent length and weight were measured by trained researchers.

Daily frequency (times/day), energy (kcal/day), and overconsumed nutrients from snack food intake were calculs and toddlers and contribute to the intake of overconsumed nutrients such as added sugars and sodium. Given the current guidelines to avoid added sugars and higher sodium before age 2 years, additional recommendations related to nutrient-dense snack intake may be beneficial.

Calcium, one of the most abundant minerals in the human body, has a pivotal role in human physiology. However, only a few studies have examined the association of dietary calcium intake with mortality in a population with low calcium intake.

The aim of this study was to examine the association of dietary calcium intake with risk of all-cause and cause-specific mortality among Korean adults with low calcium intake.

This study was a prospective cohort study.

The analysis was conducted using data from 44,327 eligible Korean adults aged 19 years and older who participated in the Korea National Health and Nutrition Examination Survey 2007-2015. Dietary calcium intake was assessed using 1-day 24-hour recall data.

The main outcomes of this study were mortality from all causes, cancer, cardiovascular disease, respiratory disease, and all other causes combined. The outcome was ascertained through linkage to the death registry compiled by Statistics Korea with the use of the resident registration number.

Wessociated with a higher risk of all-cause mortality.SHP1 is a non-receptor protein tyrosine phosphatase that is widely expressed in hematopoietic cells such as white blood cells, neutrophils, and immune cells. SHP1 can regulate the occurrence and differentiation of immune cells and plays an important role as a tumor suppressor. Previous studies have suggested that SHP2, the homologous protein of phosphatase SHP1, can undergo liquid-liquid phase separation (LLPS). Therefore, in this study, we investigated if SHP1 is also capable of LLPS. To the best of our knowledge, our study is the first to reveal that SHP1 has the ability to undergo LLPS. In addition, we identified an important residue, SHP1-R360E, that can completely inhibit the LLPS ability of SHP1, but this mutation has no remarkable effect on SHP1's enzymatic activity. This allows us to explore the phosphatase activity and phase separation ability of SHP1 separately, providing a basis for future exploration of the phase separation mechanism of phosphatases.

Intrathecal baclofen (ITB) is a treatment modality used to improve the quality of life of patients with intractable spasticity and dystonia. Although it is an effective solution in patients failing oral interventions, it is associated with potential infectious complications. It is known that pediatric patients with ITB have significantly higher infection rates compared with adult patients. The cause of these higher rates in pediatric patients remains unclear. In the present study, we performed a meta-analysis focusing on the incidence of infection, and clarification of potential risk factors for infection in pediatric patients with ITB.

This meta-analysis was performed in accordance with the PRISMA guidelines. An electronic database search was performed through PubMed, Web of Science, Embase, and Cochrane Library databases. Eligibility criteria and bias assessment were applied before statistical analysis.

The 17 studies identified yielded 2238 pediatric patients treated with implanted ITB pumps between 1994 and 2014. Infection comprised 34% of observed complications, second only to catheter malfunction. Pediatric ITB primary infection ranged between 0% and 44% among included studies (interquartile range, 4.85%-18.85%). A linear mixed-effects regression model showed that subfascial implantation had 12% lower primary infection rates compared with subcutaneous implantations across the literature. The relative risk of infection was 56% lower in pediatric patients with subfascially implanted ITB pumps.

Surgeons and clinicians should use these data to better assess patient risk-benefit when considering ITB pump implantation.

Intraoperative neuromonitoring (IONM) is useful during spinal cord operations, but whether IONM is necessary for posterior cervical surgeries for degenerative conditions is unknown. We evaluated the utility of somatosensory evoked potential (SSEP) and motor evoked potential (MEP) monitoring as a tool for predicting new postoperative neurologic deficits during posterior decompression and fusion for degenerative cervical spine conditions.

We retrospectively reviewed posterior cervical operations performed at our institute over a 4-year period. Patients with postoperative neurologic deficits were identified, and a detailed analysis performed to ascertain whether SSEP or MEP monitoring accurately predicted the onset of new postoperative deficits.

Overall, 498 patients were included in the analysis (median age 66 years; range 22-93 years). SSEP monitoring was performed in all patients, and both SSEP and MEP monitoring were performed in 121 patients (24%). learn more Twenty-one patients (4.2%) had new postoperative neurologic deficits.
