We report two siblings with intractable epilepsy, developmental regression, and progressive cerebellar atrophy due to biallelic variants in the gene CAD. For the affected girl, uridine started at age 5 resulted in dramatic improvements in seizure control and development, cessation of cerebellar atrophy, and resolution of hematological abnormalities. Her older brother had a more severe course and only modest response to uridine started at 14 years old. Treatment of this progressive condition via uridine supplementation provides an example of precision diagnosis and treatment using clear outcome measures and biomarkers to monitor efficacy.Direct conversion of carbon dioxide into multicarbon liquid fuels by the CO2 electrochemical reduction reaction (CO2 RR) can contribute to the decarbonization of the global economy. Here, well-defined Cu2 O nanocubes (NCs, 35 nm) uniformly covered with Ag nanoparticles (5 nm) were synthesized. When compared to bare Cu2 O NCs, the catalyst with 5 at % Ag on Cu2 O NCs displayed a two-fold increase in the Faradaic efficiency for C2+ liquid products (30 % at -1.0 VRHE ), including ethanol, 1-propanol, and acetaldehyde, while formate and hydrogen were suppressed. Operando X-ray absorption spectroscopy revealed the partial reduction of Cu2 O during CO2 RR, accompanied by a reaction-driven redispersion of Ag on the CuOx  NCs. Data from operando surface-enhanced Raman spectroscopy further uncovered significant variations in the CO binding to Cu, which were assigned to Ag-Cu sites formed during CO2 RR that appear crucial for the C-C coupling and the enhanced yield of liquid products.
Improper use of asthma inhalers is one of the potential factors of poor asthma control among children. This study aimed to assess the proper handling of asthma inhalers and asthma control in addition to factors influencing them among pediatric patients who self-administer their inhalers.

A cross-sectional study was conducted in Jordan from February 2019 to February 2020. All eligible pediatric patients with asthma attending outpatient settings were approached. The inhalation technique was assessed according to a standard checklist, and asthma control was assessed using the Asthma Control Test.

A total of 150 patients were included in this study. A metered dose inhaler (MDI) was the most commonly used inhaler device (89.4%) which was used appropriately by only 13.4% of participants. Whereas, appropriate use of Turbohaler and Diskus was reported by 38.5% and 28.9%, respectively. The higher level of parental knowledge was associated with higher number of correct MDI steps (OR = 1.066; 95% CI = 1.010-1.125; p = .020) and less reported errors in critical steps (OR = 0.949; 95% CI = 0.900-0.999; p = .047). Higher level of both parental education and pediatric average stigma score (less stigmatized) were associated with better asthma control ([OR = 5.181; 95% CI = 1.238-21.677; p = .024], [OR = 2.825; 95% CI = 1.420-5.619; p = .003], respectively).

Continuous education on appropriate inhaler self-administration for asthmatic children is highly recommended. Clinical pharmacists play a major role toward improving the administration of inhalers through patient training and counseling.

Relationships between iron-dependent ferroptosis and nerve system diseases have been recently revealed. However, the role of ferroptosis in neuropathic pain (NeP) remains to be elucidated. Thus, we aimed to investigate whether ferroptosis in spinal cord contributes to NeP induced by a chronic constriction injury (CCI) of the sciatic nerve.

Forty Sprague-Dawley rats received CCI or sham surgery, and were randomly assigned to the following four groups sham group; CCI+LIP group; CCI+Veh group; and CCI group. Liproxstatin-1 or corn oil were separately injected intraperitoneally for three consecutive days after surgery in the CCI+LIP or CCI+Veh group. The mechanical and thermal hypersensitivities were tested after surgery. Biochemical and morphological changes related to ferroptosis in the spinal cord were also assessed. These included iron content, glutathione peroxidase 4 (GPX4) and anti-acyl-CoA synthetase long-chain family member 4 (ACSL4) expression, lipid peroxidation assays, as well as mitochondrial morivities. This knowledge suggested that ferroptosis could represent a potential therapeutic target for neuropathic pain.
The spinal ferroptosis-like cell death was involved in the development of neuropathic pain resulted from peripheral nerve injury, and inhibition of ferroptosis by liproxstatin-1 could alleviate mechanical and thermal hypersensitivities. This knowledge suggested that ferroptosis could represent a potential therapeutic target for neuropathic pain.
To investigate the present status of anxiety among nurses fighting the spread of COVID-19 and its association with perceived stress and insomnia.

With the outbreak of COVID-19, nurses have been caring for infected patients for a considerable length of time in Wuhan, China. Previous COVID-19 studies generally focused on patients' medical treatment, but few considered healthcare workers' psychological needs while working with a pandemic involving an unfamiliar infectious disease. Numerous nurses have experienced mental health problems, such as anxiety.

The STROBE guidelines for a cross-sectional questionnaire were implemented.

An online survey of 643 frontline nurses working with COVID-19 patients was conducted from March 3 to 10, 2020. Sociodemographic data were collected, and the Generalized Anxiety Disorder Scale, the Chinese Perceived Stress Scale, and the Athens Insomnia Scale were administered.

One-third (33.4%) of participants reported anxiety, which was associated with perceived stress and insmore importantly, health care authorities and nursing managers need to pay more attention to ensuring intervention training to reduce anxiety for frontline nurses worldwide.
Sacubitril/valsartan (sac/val) has shown superior effect compared with blockade of the renin-angiotensin-aldosterone system in heart failure with reduced ejection fraction. We aimed to investigate effects of sac/val compared with valsartan in a pressure overload model of heart failure with preserved ejection fraction (HFpEF).

Sprague-Dawley rats underwent aortic banding or sham (n=16) surgery and were randomized to sac/val (n=28), valsartan (n=29), or vehicle (n=26) treatment for 8weeks. Sac/val reduced left ventricular weight by 11% compared with vehicle (P=0.01) and 9% compared with valsartan alone (P=0.04). TVB-2640 mouse Only valsartan reduced blood pressure compared with sham (P=0.02). Longitudinal early diastolic strain rate was preserved in sac/val compared with sham, while it was reduced by 23% in vehicle (P=0.03) and 24% in valsartan (P=0.02). Diastolic dysfunction, measured by E/e'SR, increased by 68% in vehicle (P<0.01) and 80% in valsartan alone (P<0.001), while sac/val showed no increase. Neither sac/od pressure. Early systolic dysfunction was not affected, supporting the notion that sac/val has the largest potential in conditions characterized by reduced ejection fraction. Observed anti-hypertrophic effects in preserved ejection fraction implicate potential benefit of sac/val in the clinical setting of hypertrophic remodelling and impaired diastolic function.
Mutations in CLN3 cause Batten disease, however non-syndromic CLN3 disease, characterized by retinal-specific degeneration, has been also described. Here, we characterized an induced pluripotent stem cell (iPSC)-derived disease model derived from a patient with non-syndromic CLN3-associated retinopathy.

Patient-iPSC, carrying the 1kb-deletion and c.175G>A variants in CLN3, coisogenic iPSC, in which the c.175G>A variant was corrected, and control iPSC were differentiated into neural retinal organoids (NRO) and cardiomyocytes. CLN3 transcripts were analyzed by Sanger sequencing. Gene expression was characterized by qPCR and western blotting. NRO were characterized by immunostaining and electron microscopy.

Novel CLN3 transcripts were detected in adult human retina and control-NRO. The major transcript detected in patient-NRO displayed skipping of exons 2 and 4-9. Accumulation of subunit-C of mitochondrial ATPase (SCMAS) protein was demonstrated in patient-derived cells. Photoreceptor progenitor cells in patient-NRO displayed accumulation of peroxisomes and vacuolization of inner segments. Correction of the c.175G>A variant restored CLN3 mRNA and protein expression and prevented SCMAS and inner segment vacuolization.

Our results demonstrate the expression of novel CLN3 transcripts in human retinal tissues. The c.175G>A variant alters splicing of the CLN3 pre-mRNA, leading to features consistent with CLN3 deficiency, which were prevented by gene correction.

Effects of aging on T-cell metabolism and the potential to interfere with immunosuppressants have not been explored yet. Here, we dissected metabolic pathways of CD4+ and CD8+ T cells in aging and offer novel immunosuppressive targets. Upon activation, CD4+ T cells from old mice failed to exhibit adequate metabolic reprogramming resulting into compromised metabolic pathways, including oxidative phosphorylation (OXPHOS) and glycolysis. Comparable results were also observed in elderly human patients. Although glutaminolysis remained the dominant and age-independent source of mitochondria for activated CD4+ T cells, old but not young CD4+ T cells relied heavily on glutaminolysis. Treating young and old murine and human CD4+ T cells with 6-diazo-5-oxo-l-norleucine (DON), a glutaminolysis inhibitor resulted in significantly reduced IFN-γ production and compromised proliferative capacities specifically of old CD4+ T cells. Of translational relevance, old and young mice that had been transpvel and age-specific approaches for immunosuppression.Strategies to mitigate the pathologies from diabetes range from simply administering insulin to prescribing complex drug/biologic regimens combined with lifestyle changes. There is a substantial effort to better understand β-cell physiology during diabetes pathogenesis as a means to develop improved therapies. The convergence of multiple fields ranging from developmental biology to microfluidic engineering has led to the development of new experimental systems to better study complex aspects of diabetes and β-cell biology. Here we discuss the available insulin-secreting cell types used in research, ranging from primary human β-cells, to cell lines, to pluripotent stem cell-derived β-like cells. Each of these sources possess inherent strengths and weaknesses pertinent to specific applications, especially in the context of engineered platforms. We then outline how insulin-expressing cells have been used in engineered platforms and how recent advances allow for better mimicry of in vivo conditions. Chief among these conditions are β-cell interactions with other endocrine organs.
