Superconductivity in infinite-layer nickelates has stirred much research interest, to which questions regarding the nature of superconductivity remain elusive. A critical leap forward to address these intricate questions is through the growth of high-crystallinity infinite-layer nickelates, including the "parent" phase. Here, we report the synthesis of a high-quality thin-film nickelate, NdNiO.

Prognostic assessment in chronic lymphocytic leukemia (CLL) is essential for delivery of timely, personalized therapy. status, karyotype, IGHV mutational status, minimal residual disease (MRD), gene mutations and markers of cell proliferation were important prognostic tools in the era of chemo-immunotherapy (CIT). With BCL2 inhibitors (BCL2i), outcome is still impacted by IGHV status, status, complex karyotype, and achievement of undetectable MRD.

The endocrine consequences of weight loss by bariatric surgery (BS) and caloric restriction are not fully understood but contribute to variable improvements in insulin sensitivity and cardiometabolic health. This study compared changes in insulin sensitivity and plasma concentrations of gut peptides 8 weeks and 1 year after BS and a low-calorie diet (LCD). Nineteen female patients with obesity self-selected BS (gastric bypass [n = 5] or sleeve gastrectomy [n = 7]) or LCD (n = 7) in this parallel-arm, prospective observational study.

Background: Mislabelled penicillin allergies are associated with a myriad of adverse outcomes and development of anti-microbial resistance. With the overwhelming need for specialist allergy services, pharmacist initiatives such as the Hong Kong Penicillin Allergy Pharmacist Initiative (HK-PAPI) have been advocated. However, evidence of their effectiveness, safety and impact on health-related quality-of-life (HR-QoL) are lacking.

Peripheral neuropathy (PN) is a significant cause of morbidity associated with Waldenström macroglobulinemia (WM). The phase 3 ASPEN study compared the efficacy and safety of zanubrutinib with ibrutinib in patients with WM. This ad hoc analysis examined treatment outcomes with zanubrutinib or ibrutinib on PN symptoms associated with WM in patients enrolled in ASPEN.

Article Synopsis
  • Monogenic diabetes results from rare gene mutations affecting beta cell function, and this study examines how common variants may also influence young-onset type 2 diabetes (YOD) and related health issues.
  • Researchers created a weighted polygenic risk score (wPRS) using data from individuals with and without YOD to explore the association of 135 common variants across 34 monogenic diabetes genes.
  • The findings indicate that higher wPRS correlates with an increased likelihood of YOD and a higher risk for cardiovascular and kidney events in individuals with type 2 diabetes.

Aims/hypothesis: Type 2 diabetes is a complex and heterogeneous disease and the aetiological components underlying the heterogeneity remain unclear in the Chinese and East Asian population. Therefore, we aimed to investigate whether specific pathophysiological pathways drive the clinical heterogeneity in type 2 diabetes.

Methods: We employed newly developed type 2 diabetes hard-clustering and soft-clustering pathway-specific polygenic risk scores (psPRSs) to characterise individual genetic susceptibility to pathophysiological pathways implicated in type 2 diabetes in 18,217 Chinese patients from Hong Kong.

Article Synopsis
  • * The article examines the effectiveness of combining ibrutinib and venetoclax in treating relapsed or refractory MCL based on findings from two clinical studies: the AIM study, which involves a run-in period with ibrutinib, and the SYMPATICO study, which administers both drugs simultaneously.
  • * It suggests that this combination therapy may be effective and could eventually allow for fixed-duration treatment; ongoing research into measurable residual disease may help determine which patients can safely stop treatment after

Aims/hypothesis: N-terminal pro B-type natriuretic peptide (NT-proBNP) is a natriuretic peptide that is strongly associated with congestive heart failure (CHF). The utility of NT-proBNP for prediction of cardiovascular events and renal endpoints, compared with clinical risk factors, has not been evaluated in detail. We hypothesise that NT-proBNP can improve risk stratification and prediction of cardiorenal events in type 2 diabetes, beyond that provided by clinical risk factors.

Article Synopsis
  • Venetoclax is a novel drug that improves outcomes for chronic lymphocytic leukemia (CLL) patients, showing that early treatment response can predict long-term success.
  • Researchers used mass cytometry to analyze blood samples from CLL patients and found that venetoclax significantly reduced various CLL cell subpopulations while increasing survival proteins in the remaining cells.
  • The study suggests that CLL cells quickly adapt to therapies through survival signals like the B-cell activating factor (BAFF), indicating that combining treatments might lead to more effective and lasting results.

RNA-binding proteins (RBPs) are key regulators of gene expression. Here, we introduce EuPRI (Eukaryotic Protein-RNA Interactions) - a freely available resource of RNA motifs for 34,736 RBPs from 690 eukaryotes. EuPRI includes binding data for 504 RBPs, including newly collected RNAcompete data for 174 RBPs, along with thousands of reconstructed motifs.

Background: While the National Institutes of Health emphasize integrating sex as a biological variable into research, specific considerations of sex-related differences in pulmonary embolism (PE) mortality trends remain scarce. This study examines sex-based PE mortality trends across regional and demographic groups in the USA from 1999 to 2020.

Methods: A retrospective analysis of National Center for Health Statistics mortality data from 1999 to 2020 was conducted.

  • The study aimed to create and test a new framework called PACE (Population And ContExt) for adapting patient decision aids (PtDAs), specifically focusing on contraceptive options for Chinese-speaking migrant women in Australia.
  • The PACE framework included six stages: selection and appraisal, content expert review, pre-testing for usability, translation, assessing decisional needs, and testing acceptability and feasibility,
  • The pilot results showed that the adapted PtDAs were well-received by users, and the study highlighted the need for a flexible, team-based approach for successful adaptation in diverse contexts.

  • Interleukin 11 (IL11) was initially developed as a treatment for low platelet levels but has shown serious cardiac side effects, prompting researchers to investigate its toxic effects on heart cells for the first time.
  • The study involved injecting recombinant IL11 into mice and using various scientific techniques to assess its effects on heart function and gene expression, revealing drastic reductions in heart performance and increased activation of inflammatory pathways.
  • Findings from cardiomyocyte-specific knockout mouse models showed that IL11 directly induces stress responses and gene expression changes in heart cells, further solidifying its role in heart toxicity rather than protection.

Article Synopsis
  • Researchers developed a model to study how well targeted nanoparticles, specifically anti-CD20-functionalized poly(ethylene glycol) (PEG) particles, can track and attack chronic lymphocytic leukemia (CLL) cells in patients' blood, showing significant variability in effectiveness among individuals.
  • The study found that while these nanoparticles generally targeted CLL cells effectively, there was up to 234-fold difference in targeting efficacy and considerable off-target effects, killing almost all monocytes in a short period.
  • Anti-PEG antibodies in patients' blood were identified as important factors affecting how well the nanoparticles targeted CLL cells, alongside other factors like cell antigen expression and nanoparticle properties, highlighting the complexity of personalized medicine in cancer treatment.

  • BamA is a crucial part of the β-barrel assembly machine (BAM) that helps insert proteins into the outer membrane of Gram-negative bacteria like E. coli.
  • Researchers used in vitro selection techniques to find peptide macrocycles that can disrupt BamA's function by binding to different conformational states, specifically Peptide Targeting BamA-1 (PTB1) and Peptide Targeting BamA-2 (PTB2).
  • These findings are important for developing new antibiotics targeting BamA and could also be applied to discover modulators for other similar proteins in the future.
