Current and Emerging Therapies for Lysosomal Storage Disorders.

Drugs

January 2025

Lysosomal Storage Disorders Unit, Royal Free London NHS Foundation Trust, University College London, London, NW3 2QG, UK.

Lysosomal storage disorders (LSDs) are rare inherited metabolic disorders characterized by defects in the function of specific enzymes responsible for breaking down substrates within cellular organelles (lysosomes) essential for the processing of macromolecules. Undigested substrate accumulates within lysosomes, leading to cellular dysfunction, tissue damage, and clinical manifestations. Clinical features vary depending on the degree and type of enzyme deficiency, the type and extent of substrate accumulated, and the tissues affected.

Disentangling the neural underpinnings of response inhibition in disruptive behavior and co-occurring ADHD.

Eur Child Adolesc Psychiatry

January 2025

Department of Child and Adolescent Psychiatry, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

While impaired response inhibition has been reported in attention-deficit/hyperactivity disorder (ADHD), findings in disruptive behavior disorders (DBDs) have been inconsistent, probably due to unaccounted effects of co-occurring ADHD in DBD. This study investigated the associations of behavioral and neural correlates of response inhibition with DBD and ADHD symptom severity, covarying for each other in a dimensional approach. Functional magnetic resonance imaging data were available for 35 children and adolescents with DBDs (8-18 years old, 19 males), and 31 age-matched unaffected controls (18 males) while performing a performance-adjusted stop-signal task.

The long-term clinical outcomes and associated prognostic factors in contactin-associated protein-like 2 (CASPR2)-antibody diseases are unknown. A total of 75 participants with CASPR2 antibodies were longitudinally assessed for disability, quality-of-life, and chronic pain. Although most symptoms improved within 6 months of treatment, neuropathic pain and fatigue were the most immunotherapy refractory, and persisted for up to 6 years.

The accurate assessment of body composition in cirrhosis is challenging as fluid accumulation affects most techniques. The whole-body counter is a state-of-the-art method that measures total body potassium (TBK) unbiased by fluid, from which body cell mass (BCM) is derived. This pilot study in 20 patients with cirrhosis evaluated bedside tools including the liver frailty index (LFI), bioimpedance analysis-based phase angle, calf circumference (CC), and BMI (body mass index)/edema-adjusted CC, and explored their association with TBK and BCM.

Human epidermal growth factor receptor 2 (HER2, also known as ERBB2) signaling promotes cell growth and differentiation, and is overexpressed in several tumor types, including breast, gastric and colorectal cancer. HER2-targeted therapies have shown clinical activity against these tumor types, resulting in regulatory approvals. However, the efficacy of HER2 therapies in tumors with HER2 mutations has not been widely investigated.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disease with the age at which characteristic symptoms manifest strongly influenced by inherited HTT CAG length. Somatic CAG expansion occurs throughout life and understanding the impact of somatic expansion on neurodegeneration is key to developing therapeutic targets. In 57 HD gene expanded (HDGE) individuals, ~23 years before their predicted clinical motor diagnosis, no significant decline in clinical, cognitive or neuropsychiatric function was observed over 4.

There is an ongoing need to identify novel pharmacological agents for the effective treatment of depression. One emerging candidate, which has demonstrated rapid-acting antidepressant effects in treatment-resistant groups, is nitrous oxide (NO)-a gas commonly used for sedation and pain management in clinical settings and with a range of pharmacological effects, including antagonism of NMDA glutamate receptors. A growing body of evidence suggests that subanaesthetic doses of NO (50%) can interfere with the reconsolidation of maladaptive memories in healthy participants and across a range of disorders.

The comprehensive benefit evaluation of LID based on multi-criteria decision-making methods faces technical issues such as the uncertainties and vagueness in hybrid information sources, which can affect the overall evaluation results and ranking of alternatives. This study introduces a multi-indicator fuzzy comprehensive benefit evaluation approach for the selection of LID measures, aiming to provide a robust and holistic framework for evaluating their benefits at the community level. The proposed methodology integrates quantitative environmental and economic indicators with qualitative social benefit indicators, combining the use of the Storm Water Management Model (SWMM) and ArcGIS for scenario-based analysis, and the use of hesitant fuzzy language sets and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) for decision-making.

Accurately representing the relationships between nitrogen supply and photosynthesis is crucial for reliably predicting carbon-nitrogen cycle coupling in Earth System Models (ESMs). Most ESMs assume positive correlations amongst soil nitrogen supply, leaf nitrogen content, and photosynthetic capacity. However, leaf photosynthetic nitrogen demand may influence the leaf nitrogen response to soil nitrogen supply; thus, responses to nitrogen supply are expected to be the largest in environments where demand is the greatest.

Sex and Cardiac Operations: Are We Being Fair to Our Female Patients?

Heart Lung Circ

January 2025

Division of Cardiovascular Research, School of Medcine, University of Dundee, Ninewells Hospital, Dundee, UK. Electronic address:

Background: Research suggests that although men have a higher cardiovascular disease (CVD) rate, women with CVD are more likely to experience a poorer prognosis, possibly owing to incorrect diagnosis and poorer treatment. A question not yet addressed is whether some of this inequality could be due to sex bias when selecting patients for operation.

Method: The participants were from the Scottish Heart Health Extended Cohort who had been admitted to hospital with a cardiovascular diagnosis over the study period.
