NSAID Allergy Labels Associated With Mortality and Cardiovascular Outcomes in Stroke.

Stroke

January 2025

Division of Rheumatology and Clinical Immunology (C.C.W.T., H.W.F.M., P.H.L.), Department of Medicine, The University of Hong Kong, Pokfulam.

Article Synopsis
  • The study examined how mislabeled drug allergies, particularly to NSAIDs, affect stroke patients compared to the general population in Hong Kong from 2008 to 2014.
  • Patients with stroke had a higher prevalence of allergy labels for cardiovascular and diagnostic agents, impacting their treatment options and medication prescriptions.
  • Notably, those labeled with NSAID allergies were less likely to receive important medications like aspirin, faced higher mortality rates, and most could be delabeled successfully through testing.

Article Synopsis
  • Dermatomyositis (DM) with anti-MDA5 antibodies, particularly when associated with rapidly progressive interstitial lung disease (RP-ILD), is considered hard to treat.
  • A significant case of clinically amyopathic dermatomyositis (CADM) with RP-ILD demonstrated a poor response to conventional treatments but improved after adding mycophenolate mofetil (MMF), leading to controlled symptoms and decreased antibody levels.
  • The report emphasizes the need for more research to better understand the role of inflammatory cytokines in CADM/RP-ILD and to explore MMF's potential for long-term treatment.

Perspectives of Young People on Social Media-Based Sexuality Education Using a Feminist Approach in China: A Qualitative Study.

Arch Sex Behav

November 2024

Department of Family Medicine and Primary Care, Li Ka Shing Faculty of Medicine, The University of Hong Kong, 3/F, Ap Lei Chau Clinic, 161 Main Street, Ap Lei Chau, Hong Kong SAR, China.

The feminist approach to sexuality education challenges and changes power dynamics and inequalities embedded within sexuality, while social media serves as a tool for building online communities and raising awareness about feminist issues. Adopting a feminist approach to sexuality education, particularly through social media platforms, remains largely unexplored and underdeveloped. In China, where traditional sex education is often limited and stigmatized, sexuality has been influenced by a complex interplay of traditional gender norms, evolving social attitudes, and state intervention.

GPRC5A promotes lung colonization of esophageal squamous cell carcinoma.

Nat Commun

November 2024

Department of Clinical Oncology, Centre for Cancer Medicine, Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong SAR, China.

Emerging evidence suggests that cancer cells may disseminate early, prior to the formation of traditional macro-metastases. However, the mechanisms underlying the seeding and transition of early disseminated cancer cells (DCCs) into metastatic tumors remain poorly understood. Through single-cell RNA sequencing, we show that early lung DCCs from esophageal squamous cell carcinoma (ESCC) exhibit a trophoblast-like 'tumor implantation' phenotype, which enhances their dissemination and supports metastatic growth.

Telemed J E Health

November 2024

Department of Family Medicine and Primary Care, School of Clinical Medicine, Li Ka Shing Faculty of Medicine, The University of Hong Kong, Hong Kong, China.

Article Synopsis
  • A study surveyed the general population in Hong Kong to assess their willingness to use teleconsultation in primary care, identifying factors influencing their decisions and the medical issues for which they would consider it.
  • About 51.6% of respondents were open to using teleconsultation, with major motivations being belief in its effectiveness for health issues, government subsidies, and access to technology, while low education levels posed a significant barrier.
  • The findings suggest the need for healthcare providers and the government to address these motivations and barriers, as well as to correct misconceptions, to promote teleconsultation in Hong Kong's primary care system.

Diabetic kidney disease (DKD) is the leading cause of end-stage kidney diseases resulting in enormous socio-economic burden. Accumulated evidence has indicated that C-reactive protein (CRP) exacerbates DKD by enhancing renal inflammation and fibrosis through TGF-β/Smad3 signaling. NLRP3 inflammasome is the key sensor contributing to renal inflammation.

  • Mismatch repair (MMR) deficiency can lead to diseases like constitutional mismatch repair deficiency (CMMRD) syndrome and Lynch syndrome (LS), both linked to various tumors, including brain cancers, mainly affecting adults but with some pediatric cases.
  • A study from hospitals in Hong Kong identified five patients with MMR gene mutations, revealing that four had CMMRD syndrome with various brain tumors and one had LS associated with a medulloblastoma at age 10.
  • The study noted that all CMMRD patients had café-au-lait macules (CALMs) since birth, and highlighted the challenges in diagnosing CMMRD due to similarities with other syndromes, emphasizing the need for better clinical differentiation of CALM-related genetic

  • Pelvic organ prolapse (POP) is a common issue affecting many women worldwide, and recent research highlights the effectiveness of laparoscopic pectopexy (LP) but points out its cost and complications due to synthetic mesh.
  • A new procedure called laparoscopic non-mesh cerclage pectopexy with uterine preservation (LNMCPUP) has been developed, allowing for successful uterine suspension without using mesh, resulting in high success rates and minimal complications.
  • This technique not only avoids the risks associated with synthetic mesh but also offers a solution for women who want to keep their uterus during surgery, making it a viable option especially in areas where mesh is not accessible.

Article Synopsis
  • Preeclampsia (PE) is a common pregnancy complication with unclear causes, and BMP5, a glycoprotein in the placenta, may play a crucial role in trophoblast cell function.
  • The study found that BMP5 expression and its N-glycosylation are lower in preeclamptic tissues, suggesting that changes in BMP5 may affect cell behaviors like proliferation and invasion.
  • Ultimately, the research indicates that N-glycosylated BMP5 enhances trophoblastic functions through the BMP5-SMAD1/5 signaling pathway, offering new insights for diagnosing and treating preeclampsia.

Targeting ATAD3A Phosphorylation Mediated by TBK1 Ameliorates Senescence-Associated Pathologies.

Adv Sci (Weinh)

November 2024

Guangdong Cardiovascular Institute, Medical Research Institute, Guangdong Provincial People's Hospital (Guangdong Academy of Medical Sciences), Southern Medical University, Guangzhou, 510080, China.

Targeting cellular senescence, one of the hallmarks of aging and aging-related pathologies emerges as an effective strategy for anti-aging and cancer chemotherapy. Here, a switch from TBK1-OPTN axis to TBK1-ATAD3A axis to promote cellular senescence is shown. Mechanically, TBK1 protein is abnormally activated and localized to the mitochondria during senescence, which directly phosphorylates ATAD3A at Ser321.

Electronic address:

Patients with type 2 diabetes (T2D) are more susceptible to severe respiratory viral infections, but the underlying mechanisms remain elusive. Here, we show that patients with T2D and coronavirus disease 2019 (COVID-19) infections, and influenza-infected T2D mice, exhibit defective T helper 1 (Th1) responses, which are an essential component of anti-viral immunity. This defect stems from intrinsic metabolic perturbations in CD4 T cells driven by hyperglycemia.

Article Synopsis
  • - Sjögren's syndrome (SS) is an autoimmune disease characterized by symptoms like dry eyes and mouth, primarily affecting the lacrimal and salivary glands, leading to irreversible damage known as glandular fibrosis due to chronic inflammation.
  • - The exact mechanisms behind glandular fibrosis in SS are not well understood, but it’s believed to involve interactions between immune cells and glandular epithelial cells, along with factors like TGF-β and extracellular matrix remodeling.
  • - There is a potential link between viral infections, such as COVID-19, and the worsening of SS symptoms, as viral responses can intensify autoimmune reactions and lead to increased inflammation in the salivary glands.
