Pilot study of a ketogenic diet in bipolar disorder.

Background: Recent evidence from case reports suggests that a ketogenic diet may be effective for bipolar disorder. However, no clinical trials have been conducted to date.

Aims: To assess the recruitment and feasibility of a ketogenic diet intervention in bipolar disorder.

Association of Fentanyl Test Strip Use, Perceived Overdose Risk, and Naloxone Possession among People Who Use Drugs.

As opioid overdoses continue rising, interventions are needed to expand naloxone carriage, an opioid overdose reversal agent. Use of fentanyl test strips (FTS) might promote naloxone carriage. This study examines the relationship between FTS use, perceived overdose risk, and naloxone carriage in Wisconsin, United States.

Genotype-stratified treatment for monogenic insulin resistance: a systematic review.

Background: Monogenic insulin resistance (IR) includes lipodystrophy and disorders of insulin signalling. We sought to assess the effects of interventions in monogenic IR, stratified by genetic aetiology.

Methods: Systematic review using PubMed, MEDLINE and Embase (1 January 1987 to 23 June 2021).

The Queen Square Encephalitis Multidisciplinary Team Meeting - experience over three years, pre and post the COVID-19 pandemic.

Background: Patients with suspected encephalitis continue to represent a diagnostic and therapeutic challenge, even in highly resourced centres. In February 2018, we set up a monthly in-person multidisciplinary team meeting (MDT). We describe the experience and outcomes of the MDT over three years.

The sterol transporter STARD3 transports sphingosine at ER-lysosome contact sites.

Sphingolipids are important structural components of membranes. Additionally, simple sphingolipids such as sphingosine are highly bioactive and participate in complex subcellular signaling. Sphingolipid deregulation is associated with many severe diseases including diabetes, Parkinson's and cancer.

MTGR1 is required to maintain small intestinal stem cell populations.

Undifferentiated intestinal stem cells (ISCs), particularly those marked by , are crucial for maintaining homeostasis and resolving injury. + cells in the crypt base constantly divide, pushing daughter cells upward along the crypt axis, where they differentiate into a variety of specialized cell types. This process requires coordinated execution of complex transcriptional programs, which allow for the maintenance of undifferentiated stem cells while permitting differentiation of the wide array of intestinal cells necessary for homeostasis.

Volumetrically tracking retinal and choroidal structural changes in central serous chorioretinopathy.

Central serous chorioretinopathy (CSCR) leads to accumulation of subretinal fluid and retinal thickness change, which can be readily detected in clinics using optical coherence tomography (OCT). However, current quantification methods usually require sophisticated processing such as retinal layer segmentations, and volumetric visualization of structural changes is generally challenging, which can hinder fast and accurate assessment of disease progression and/or treatment efficacy. In this study, we developed an algorithm that can register the OCT scans acquired from different visits without requiring prior layer segmentation and calculated the three-dimensional (3-D) structural change maps for patients with CSCR.

Phase 1 study of JNJ-64619178, a protein arginine methyltransferase 5 inhibitor, in patients with lower-risk myelodysplastic syndromes.

Splicing factor (SF) gene mutations are frequent in myelodysplastic syndromes (MDS), and agents that modulate RNA splicing are hypothesized to provide clinical benefit. JNJ-64619178, a protein arginine methyltransferase 5 (PRMT5) inhibitor, was evaluated in patients with lower-risk (LR) MDS in a multi-part, Phase 1, multicenter study. The objectives were to determine a tolerable dose and to characterize safety, pharmacokinetics, pharmacodynamics, and preliminary clinical activity.

Predictors of Burden in Carers of Patients with Impulse Control Behaviors in Parkinson's Disease.

Background: Impulse control behaviors (ICBs) are problematic, reward-based behaviors, affecting 15% to 35% of patients with Parkinson's disease. Evidence exists of increased carer burden as a result of these behaviors; however, little is known about the variables mediating this effect and their management.

Objective: To identify factors predictive of carer burden in a cohort of patients with Parkinson's disease with ICBs to enable the development of targeted therapeutic interventions for carers.

Improving the Management of Hepatorenal Syndrome-Acute Kidney Injury Using an Updated Guidance and a New Treatment Paradigm.

Cirrhosis, or advanced scarring of the liver, represents the end stage of chronic liver disease and is associated with high morbidity and mortality. Hepatorenal syndrome-acute kidney injury (HRS -AKI), a condition causing functional and progressive kidney failure, is a complication of cirrhosis that contributes to its high mortality rate. In the United States, the standard-of-care treatments for HRS -AKI have historically been suboptimal.

Artificial microRNA suppresses C9ORF72 variants and decreases toxic dipeptide repeat proteins in vivo.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that affects motor neurons, causing progressive muscle weakness and respiratory failure. The presence of an expanded hexanucleotide repeat in chromosome 9 open reading frame 72 (C9ORF72) is the most frequent mutation causing familial ALS and frontotemporal dementia (FTD). To determine if suppressing expression of C9ORF72 gene products can reduce toxicity, we designed a set of artificial microRNAs (amiRNA) targeting the human C9ORF72 gene.

Nursing Students' Self-Efficacy and Performance in Self-Management Support for Patients in Rural Primary Care.

There is currently no evidence of undergraduate nursing students' self-efficacy and performance in self-management support for chronic diseases in rural primary care. Using the Self-Efficacy and Performance in Self-Management Support instrument, this quasi-experimental study assessed students' self-efficacy and performance in self-management support before and after implementation of a primary care enhanced curriculum. Nursing students ( n = 140) reported a significant increase in total mean scores (pretest, M = 268.

Search for Exotic Higgs Boson Decays H→AA→4γ with Events Containing Two Merged Diphotons in Proton-Proton Collisions at sqrt[s]=13 TeV.

We present the first direct search for exotic Higgs boson decays H→AA, A→γγ in events with two photonlike objects. The hypothetical particle A is a low-mass spin-0 particle decaying promptly to a merged diphoton reconstructed as a single photonlike object. We analyze the data collected by the CMS experiment at sqrt[s]=13  TeV corresponding to an integrated luminosity of 136  fb^{-1}.

Repetition costs in sequence chunking.

We examined how flexibly we plan sequences of actions when we switch between multiple action sequences. Mastering a sequential skill is assumed to involve integrating successive actions into groups known as chunks that can be efficiently planned and smoothly executed. Chunking is suggested by gains in planning efficiency for long compared to short action sequences following practice and learning associations between actions and perceptual outcomes.
