%) participants in the intravenous iron group and 47 (51%) in the oral iron group had normalised haemoglobin (odds ratio 4·65, 95% CI 2·33-9·27). Kynurenic acid antagonist There were two mild to moderate infusion-related adverse events; and five serious adverse events (three in the intravenous iron group, two in the oral iron group), unrelated to the study medication.
Intravenous iron substitution with ferric carboxymaltose was safe and yielded a better haemoglobin response than oral iron. To our knowledge, this is the first study to provide evidence of the benefits and safety of intravenous iron substitution in a low-income setting.

Documenting trends and inequalities in the prevalence of adolescent motherhood across low-income and middle-income countries (LMICs) is important to support the adolescent sexual and reproductive health target in the UN Sustainable Development Goals (SDGs). We aimed to examine time trends and sociodemographic inequalities in the prevalence of adolescent motherhood in LMICs.
We analysed data from 747 137 young women (aged 15-19 years) from 74 LMICs, using 254 nationally representative Demographic and Health Surveys done between 1990 and 2018. We estimated the population-weighted prevalence of adolescent motherhood among women aged aged 15-19 years (defined as having had a livebirth or being pregnant at the time of the survey). Trends in the prevalence were calculated at the national level using the average annual rate of change (AARC) in a subset of 61 countries with at least two surveys from different timepoints during the study period. Sociodemographic inequalities (eg, wealth quintile, level of educatiotherhood during the study period, and sociodemographic inequalities within countries persist. These results indicate that efforts to reduce adolescent motherhood and the associated health burden need to be improved within many LMICs. These findings can assist policy makers to target the rollout of interventions on the basis of observed geographic and sociodemographic inequalities to reduce adolescent motherhood among the disadvantaged, and accelerate progress towards adolescent sexual and reproductive health targets in the UN SDGs.

FHF dysfunction has been linked to neurological disorders including epilepsy. Here, we describe two sibling pairs and three unrelated males who presented in infancy with intractable focal seizures and severe developmental delay. Whole-exome sequencing identified hemi- and heterozygous variants in the N-terminal domain of the A isoform of FHF2 (FHF2A). The X-linked FHF2 gene (also known as FGF13) has alternative first exons which produce multiple protein isoforms that differ in their N-terminal sequence. The variants were located at highly conserved residues in the FHF2A inactivation particle that competes with the intrinsic fast inactivation mechanism of Nav channels. Functional characterization of mutant FHF2A co-expressed with wild-type Nav1.6 (SCN8A) revealed that mutant FHF2A proteins lost the ability to induce rapid-onset, long-term blockade of the channel while retaining pro-excitatory properties. These gain-of-function effects are likely to increase neuronal excitability consistent with the epileptic potential of FHF2 variants. Our findings demonstrate that FHF2 variants are a cause of infantile-onset developmental and epileptic encephalopathy and underline the critical role of the FHF2A isoform in regulating Nav channel function.
Prednisone is commonly used for initial short-term therapy of episodic cluster headaches before preventive medication such as verapamil becomes effective, but this strategy has not been tested in large randomised trials. We aimed to access the safety and efficacy of this treatment approach.
This study was a multicentre, randomised, double-blind, placebo-controlled trial done in ten specialised headache centres in Germany. Patients with episodic cluster headaches who were aged between 18 and 65 years and within a current pain episode for not more than 30 days, received 100 mg oral prednisone for 5 days followed by tapering of 20 mg every 3 days, or matching placebo (17 days total exposure). All patients received oral verapamil for long-term prevention, starting with 40 mg three times daily and increasing to 120 mg three times daily by day 19; patients then continued with verapamil 120 mg throughout the study. Randomisation was computer-generated at a 11 ratio by use of an interactive web-response system, wof verapamil, although the efficacy of prednisone alongside other long-term prevention requires additional investigation.

Here, we employ an integrative imaging analysis to determine morphological organelle alterations induced in SARS-CoV-2-infected human lung epithelial cells. We report 3D electron microscopy reconstructions of whole cells and subcellular compartments, revealing extensive fragmentation of the Golgi apparatus, alteration of the mitochondrial network and recruitment of peroxisomes to viral replication organelles formed by clusters of double-membrane vesicles (DMVs). These are tethered to the endoplasmic reticulum, providing insights into DMV biogenesis and spatial coordination of SARS-CoV-2 replication. Live cell imaging combined with an infection sensor reveals profound remodeling of cytoskeleton elements. Pharmacological inhibition of their dynamics suppresses SARS-CoV-2 replication. We thus report insights into virus-induced cytopathic effects and provide alongside a comprehensive publicly available repository of 3D datasets of SARS-CoV-2-infected cells for download and smooth online visualization.
