Background: A significant hurdle for potential cell-based therapies is the subsequent survival and regenerative capacity of implanted cells. While many exciting developments have demonstrated promise preclinically, cell-based therapies for intervertebral disc (IVD) degeneration fail to translate equivalent clinical efficacy.

Aims: This work aims to ascertain the clinical relevance of both a small and large animal model by experimentally investigating and comparing these animal models to human from the perspective of anatomical scale and their cellular metabolic and regenerative potential.

Mitochondrial methionyl-tRNA formyltransferase (MTFMT) is required for the initiation of translation in mitochondria. Pathogenic variants in have been described in association with clinical presentations with Leigh syndrome, as well with as multisystem involvement (particularly cardiac and ocular involvement). There is a spectrum of severity, but many reported presentations have been milder with a better prognosis than other pathogenic variants associated with Leigh syndrome.

Classical galactosemia (CG) is a disorder of galactose metabolism which results from deficiency of the enzyme galactose-1-phosphate uridylyl transferase (GALT). Treatment consists of immediately eliminating galactose from the diet in the new-born and lifelong restriction of dietary galactose. The inclusion of a wider variety of foods for people with CG may provide many benefits, including improved nutritional adequacy and quality of life.

Department of Paediatric Emergency Medicine Children's Health Ireland at Crumlin Dublin Ireland.

Article Synopsis
  • The study aims to create a simplified model for predicting whether pediatric emergency department patients will be admitted or discharged, using minimal data for better patient flow management.
  • The research involved analyzing data from 2017 and 2018, employing various statistical models and finding the best predictors such as presenting complaint and triage category to develop the low-dimensional model.
  • The findings showed that using just 8 key variables, the model can accurately predict admission or discharge probabilities, suggesting opportunities for further analysis on prediction accuracy in real-world scenarios.

Background: Pulmonary endothelial injury and microcirculatory thromboses likely contribute to hypoxemic respiratory failure, the most common cause of death, in patients with COVID-19. Randomized controlled trials (RCTs) suggest differences in the effect of therapeutic heparin between moderately and severely ill patients with COVID-19. We did a systematic review and meta-analysis of RCTs to determine the effects of therapeutic heparin in hospitalized patients with COVID-19.

Article Synopsis
  • Classical galactosemia (CG) is a rare metabolic disorder caused by a deficiency in the enzyme galactose-1-phosphate uridyltransferase, leading to long-term complications such as cognitive and neurological issues, which are not well understood.
  • This study analyzed glycosylation biomarkers in 95 CG patients and found significant differences in glycan traits compared to controls, particularly in the homozygous c.563A-G/p.Gln188Arg cohort of 49 patients.
  • The results indicated that dietary galactose intake could positively influence cognitive functioning, as higher galactose intake was correlated with improved intelligence scores and certain glycan profiles in CG patients.

Extracellular vesicles (EVs) are emerging as key players in different stages of atherosclerosis. Here we provide evidence that EVs released by mixed aggregates of monocytes and platelets in response to TNF-α display pro-inflammatory actions on endothelial cells and atherosclerotic plaques. Tempering platelet activation with Iloprost, Aspirin or a P2Y inhibitor impacted quantity and phenotype of EV produced.

Excess fibroblast growth factor 23 (FGF23), excess PTH, and an increase in extracellular calcium cause hypophosphatemia by lowering the maximum renal phosphate reabsorption threshold (TmP/GFR). We recently reported two cases of X-linked hypophosphatemia (XLH) with severe tertiary hyperparathyroidism who had normalization of TmP/GFR upon being rendered hypoparathyroid following total parathyroidectomy, despite marked excess in both C-terminal FGF23 (cFGF23) and intact FGF23 (iFGF23). We explored the effects of FGF23, PTH, and calcium on TmP/GFR in a cross-sectional study ( = 74) across a spectrum of clinical cases with abnormalities in TmP/GFR, PTH, and FGF23.

Mitochondrial 3-hydroxy-3-methylglutaryl-CoA (HMG Co-A) synthase (mHS) deficiency is an autosomal recessive disorder of ketone body synthesis which has traditionally been associated with hypoketotic hypoglycemia, hepatomegaly and encephalopathy, presenting in early childhood following a period of fasting. We report the third case of mHS deficiency presenting in the absence of hypoglycemia, with profound biochemical abnormalities and further evidence of potential specific diagnostic biomarkers. A previously well, 20-month old, unvaccinated male, of nonconsanguineous Polish heritage, presented with encephalopathy, hepatomegaly, severe metabolic acidosis, and mild hyperammonemia following a brief intercurrent illness.

Platelets are regulated by extracellular cues that impact on intracellular signaling. The endothelium releases prostacyclin and nitric oxide which stimulate the synthesis of cyclic nucleotides cAMP and cGMP leading to platelet inhibition. Other inhibitory mechanisms involve immunoreceptor tyrosine-based inhibition motif-containing receptors, intracellular receptors and receptor desensitization.
