Article Synopsis
  • Poor sleep quality is linked to cerebrovascular diseases, which can lead to cognitive decline and strokes as people age, but research on non-drug treatments is limited.
  • A study will involve Chinese participants aged 60-90 with mild vascular cognitive impairment and sleep issues, who will be assigned to different stimulation groups (hf-tRNS, tACS, or sham) over two weeks while their brain activity is monitored.
  • The study aims to evaluate the safety, feasibility, and effectiveness of high-frequency transcranial random noise stimulation (hf-tRNS) to improve cognitive function and sleep quality in these patients.

The number of people living with diabetes is expected to rise to 578 million by 2030 and to 700 million by 2045, exacting a severe socioeconomic burden on healthcare systems around the globe. This is also reflected in the increasing numbers of people with ocular complications of diabetes (namely, diabetic macular oedema (DMO) and diabetic retinopathy (DR)). In one study examining the global prevalence of DR, 35% of people with diabetes had some form of DR, 7% had PDR, 7% had DMO, and 10% were affected by these vision-threatening stages.

Purpose: To evaluate the visual outcomes and safety profile of intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy in the treatment of diabetic macular edema (DME) in real-world studies in Asian countries.

Methods: A systematic review of electronic literature databases (Embase, Medline, and the Cochrane Library from January 1, 2010, to March 16, 2021) was conducted to identify observational studies that reported clinical and safety outcomes of anti-VEGF treatments for DME in Asia. We analyzed baseline patient characteristics, treatment patterns, mean number of injections, best-corrected visual acuity (BCVA), retinal thickness, and safety outcomes.

Article Synopsis
  • Combination therapy is currently the standard treatment for relapsed/refractory non-Hodgkin's lymphoma (RR-NHL), but response rates are often low, especially in patients resistant to chemotherapy.
  • Researchers evaluated a new method called quadratic phenotypic optimization platform (QPOP), which can predict effective drug combinations using limited tumor samples from RR-NHL patients.
  • In a study involving 71 patients, QPOP-guided treatments showed improved outcomes and fewer cases of disease progression compared to traditional chemotherapy, providing a strong basis for future clinical trials on this approach.

Unlabelled: Despite the expanding portfolio of targeted therapies for adults with acute myeloid leukemia (AML), direct implementation in children is challenging due to inherent differences in underlying genetics. Here we established the pharmacologic profile of pediatric AML by screening myeloblast sensitivity to approved and investigational agents, revealing candidates of immediate clinical relevance. Drug responses ex vivo correlated with patient characteristics, exhibited age-specific alterations, and concorded with activities in xenograft models.

Purpose: Various treatment regimens are currently practiced in the treatment of CI-DMO (centre-involving diabetic macular oedema). In recent years, there has been a growing body of evidence supporting a treat and extend (T&E) regimen for DMO which offers the promise of comparable visual and anatomical outcomes while reducing injection burden. This meta-analysis was hence performed to evaluate the aforementioned outcomes in the treatment of DMO.

Knobloch syndrome is a rare collagenopathy characterized by severe early onset myopia, retinal detachment, and occipital encephalocele with various additional manifestations due to biallelic changes in the gene. Here we reported a Chinese family with two affected siblings presented with antenatal occipital encephalocele, infantile onset retinal detachment, and pronounced high myopia at early childhood. Quartet whole exome sequencing was performed in this family and identified that both siblings carried novel compound heterozygous variants in the gene (NM_001379500.

Background: Existing predictive outcomes models for type 2 diabetes developed and validated in historical European populations may not be applicable for East Asian populations due to differences in the epidemiology and complications. Despite the continuum of risk across the spectrum of risk factor values, existing models are typically limited to diabetes alone and ignore the progression from prediabetes to diabetes. The objective of this study is to develop and externally validate a patient-level simulation model for prediabetes and type 2 diabetes in the East Asian population for predicting lifetime health outcomes.

Citrin deficiency is one of the most common inborn errors of metabolism in East Asians, which may manifest as neonatal cholestasis, failure to thrive and dyslipidaemia, or recurrent hyperammonaemic encephalopathy. Its molecular diagnosis requires confirmation of the presence of biallelic pathogenic variants in SLC25A13 gene by sequencing, and analysis for a common insertion IVS16ins3kb. However, patients with compatible biochemical features but only one monoallelic pathogenic variant have remained a diagnostic challenge.

Topic: The Collaborative Ocular Tuberculosis Study (COTS), supported by the International Ocular Inflammation Society, International Uveitis Study Group, and Foster Ocular Immunological Society, set up an international, expert-led consensus project to develop evidence- and experience-based guidelines for the management of tubercular uveitis (TBU).

Clinical Relevance: The absence of international agreement on the use of antitubercular therapy (ATT) in patients with TBU contributes to a significant heterogeneity in the approach to the management of this condition.

Methods: Consensus statements for the initiation of ATT in TBU were generated using a 2-step modified Delphi technique.
