Article Synopsis
  • LV systolic strain is a potentially better indicator of heart function compared to LV ejection fraction (LVEF) in patients with mildly reduced ejection fraction heart failure (HFmrEF).
  • A study involving 1,075 hospitalized HFmrEF patients demonstrated that LV strain is significantly associated with cardiac risk and clinical outcomes, outperforming LVEF in survival predictions.
  • The research suggests that lower LV strain levels can more effectively indicate the benefits of angiotensin receptor-neprilysin inhibitor (ARNi) treatments compared to traditional LVEF, making it a valuable tool for risk assessment and therapy responsiveness in these patients.

  • Taller adults tend to have a lower risk of stroke compared to shorter individuals, with the study showing significant differences in risk based on height categories.
  • Systolic blood pressure plays a crucial role in this relationship, acting as a protective factor that helps mediate the association between height and stroke risk.
  • The findings suggest that managing systolic blood pressure could be an effective strategy for preventing strokes, particularly for those at risk.

Article Synopsis
  • The study examined the relationship between omega-3 PUFAs and stroke risk across 29 global cohorts, focusing on total, ischemic, and hemorrhagic strokes.
  • Results showed that higher levels of eicosapentaenoic acid reduced the incidence of total and ischemic strokes by 17% and 18%, respectively, while docosahexaenoic acid also lowered these risks by 12% and 14%.
  • The findings indicate that although higher omega-3 PUFA levels are linked to reduced total and ischemic stroke risks, there is no effect on hemorrhagic strokes.

Article Synopsis
  • A study was conducted to evaluate whether a new mapping technique, PRISM, could improve catheter ablation outcomes for patients with persistent atrial fibrillation (AF) when combined with traditional methods.
  • The trial involved 170 patients and showed that those who underwent the PRISM-guided procedure had a significantly higher success rate in maintaining normal heart rhythm after 12 months compared to the conventional approach.
  • The findings suggest that PRISM mapping may enhance the precision of AF treatment and reduce the recurrence of atrial arrhythmias, making it a promising alternative for persistent AF management.

High-energy, low-protein formulas (HE-LPFs) are commonly used as oral nutritional supplements (ONSs) to help provide extra calories to patients who are adhering to a low-protein diet (LPD) after diagnosis with chronic kidney disease (CKD). This randomized controlled trial aimed to evaluate the efficacy and safety of an HE-LPF as either a partial or a total replacement for one meal in pre-dialysis CKD patients. Stage 4-5 CKD patients received either a once-daily HE-LPF (HE-LPF group) or normal food (control group) for a period of 4 weeks while following an LPD.

Article Synopsis
  • This study investigates how atrial fibrillation (AF) affects death risks in patients who also have dementia, using data from Taiwan's National Health Insurance Research Database.
  • The research shows that patients with both dementia and AF have a higher likelihood of dying from all causes and specifically from cardiovascular issues compared to those with dementia alone.
  • It emphasizes the need for managing AF in dementia patients, as certain medications may help lower their risk of mortality.

We report a novel approach for establishing the number and position of CO events in individual homozygous inbred plants by combining low level EMS mutagenesis, speed breeding, whole genome shotgun sequencing and sliding window analysis of the induced molecular variant data. We demonstrate the approach by exploring CO frequency and distribution in self-fertilised progeny of the inbred barley cultivar Bowman and compare these observations to similar data obtained from a Bowman nearly isogenic line (BW230 containing a mutation in the DNA mismatch repair gene We have previously shown that decreases both plant fertility and recombination by ~50%. We compare our results to those from previously published traditional genetic analysis of F3 families derived from multiple F2 lines containing WT or mutant alleles of revealing a high level of correspondence between analyses.

The distribution of recombination events along large cereal chromosomes is uneven and is generally restricted to gene-rich telomeric ends. To understand how the lack of recombination affects diversity in the large pericentromeric regions, we analysed deep exome capture data from a final panel of 815 Hordeum vulgare (barley) cultivars, landraces and wild barleys, sampled from across their eco-geographical ranges. We defined and compared variant data across the pericentromeric and non-pericentromeric regions, observing a clear partitioning of diversity both within and between chromosomes and germplasm groups.
