Genetic susceptibility of diffuse large B-cell lymphoma: a meta genome-wide association study in Asian population.

Leukemia

December 2024

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

Diffuse large B-cell lymphoma (DLBCL) is an aggressive malignancy and the most common form of non-Hodgkin lymphoma (NHL) that occurs worldwide. To discover risk factors and pathogenesis of DLBCL, we performed the largest GWAS of DLBCL to date in samples of East Asian ancestry, consisting of 2,888 patients with DLBCL and 12,458 controls. The meta-analysis identified three novel loci, rs2233434 on 6p21.

Various genetic association studies have identified numerous single nucleotide polymorphisms (SNPs) associated with nasopharyngeal carcinoma (NPC) risk. However, these studies have predominantly focused on common variants, leaving the contribution of rare variants to the "missing heritability" largely unexplored. Here, we integrate genotyping data from 3,925 NPC cases and 15,048 healthy controls to identify a rare SNP, rs141121474, resulting in a Glu510Lys mutation in KLHDC4 gene linked to increased NPC risk.

We report a case of a 60-year-old lady with metastatic follicular thyroid carcinoma (FTC) who was presented with thyrotoxicosis and heart failure symptoms after total thyroidectomy. Clinical features and investigations led to the diagnosis of functional metastatic FTC with concomitant thyrotoxicosis. Levothyroxine therapy was stopped, and she was treated with propylthiouracil (PTU) followed by serial radioiodine treatments (RAITs) with good control of thyrotoxicosis and metastases.

Background: Middle-aged adults, defined as individuals between the ages of 45 and 64, represent a significant yet under researched group of healthcare service users. This scoping review aimed to provide a comprehensive overview of the patterns of healthcare utilisation and the factors contributing to them within this demographic.

Methods: Following PRISMA-ScR guidelines and the framework proposed by Arksey and O'Malley, a systematic literature search was conducted across PubMed, EMBASE, and the Cochrane Library databases from their inception until July 2023.

Background: Web-based advance care planning (ACP) interventions offer a promising solution to improve ACP engagement, but none are specifically designed to meet the needs of patients with heart failure and their caregivers.

Objective: We aimed to develop and assess the usability and acceptability of a web-based ACP decision aid called "My Voice," which is tailored for patients with heart failure and their caregivers.

Methods: This study's team and advisory board codeveloped the content for both patient and caregiver modules in "My Voice.

Reference dosimetry measurement in a pencil beam scanning system can exhibit dose fluctuation due to intra-spill spot positional drift. This results in a noisy reference dosimetry measurement against energy which could introduce errors in monitor unit calibration. The aim of this study is to investigate the impact of smoothing the reference dosimetry measurements on the type A uncertainty.

Background: Cholecystectomy (CCE) can affect the enterohepatic circulation of bile acids and result in gut microbiome changes. This systematic review aimed to clarify the effect of CCE on gut microbiome composition and its clinical impact.

Method: A systematic search was conducted in PubMed, Web of Science, and Scopus, combining keywords such as "cholecystectomy" or "post-cholecystectomy" with "gut microbiome," "stool microbiome," or "gut dysbiosis.

TMP: A dual modulator of apoptosis and autophagy via SHP-1 regulation in hepatocellular carcinoma.

Life Sci

December 2024

Department of Science in Korean Medicine, Kyung Hee University, 24 Kyungheedae-ro, Dongdae-mun-gu, Seoul 02447, Republic of Korea. Electronic address:

Background: Hepatocellular carcinoma (HCC) poses a significant health burden due to its high incidence, and current treatment effectiveness is hindered by drug resistance. Thus, investigation of novel therapeutic approaches derived from natural sources is crucial for improving patient outcomes.

Aims: This study aimed to explore the potential of Tetramethylpyrazine (TMP), bioactive alkaloid (ligustrazine) isolated from Chuanxiong (Ligusticum Wallichii), in targeting HCC by inducing apoptosis and enhancing autophagy.

Peripheral T-cell lymphomas with gamma-delta phenotype (GDTCL) are rare lymphoid malignancies. Beyond the well-recognized entities of extranodal lymphomas with gamma-delta phenotype as defined by the 5th edition of the WHO Classification of Hematolymphoid Tumors and 2022 International Consensus Classification, there is a group of poorly-defined gamma-delta T-cell lymphomas with predominantly nodal presentation, termed as nodal GDTCL (nGDTCL). In this study, we present a series of 12 cases of EBV-negative nGDTCL, highlighting the clinical, histopathological and molecular features of this rare entity.

Purpose: Laparoscopic cholecystectomy is the gold standard procedure for benign gallbladder disease. However, reducing ports still causes frustration when using various instruments. We investigated early perioperative outcomes of laparoscopic single site + 1 cholecystectomy using ArtiSential instruments (ArtiSential laparoscopic cholecystectomy [ALC], LIVSMED).

Background: Palliative surgery reduces debilitating symptoms attributable to cancer, and the intent is to improve health-related quality of life. Malignant bowel obstruction is a common indication. Despite positive clinical outcomes, there is a shortage of economic evaluation evidence to support wider adoption of palliative surgery.

π-HuB: the proteomic navigator of the human body.

Nature

December 2024

State Key Laboratory of Medical Proteomics, Beijing Proteome Research Center, National Center for Protein Sciences (Beijing), Beijing Institute of Lifeomics, Beijing, China.

The human body contains trillions of cells, classified into specific cell types, with diverse morphologies and functions. In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

Article Synopsis
  • * The research explored how the shape and confinement of CAFs on specially designed surfaces influence their morphology and gene expression, finding that certain conditions led to changes toward more inflammatory and desmoplastic CAF types.
  • * The findings suggest that the way CAFs are physically arranged affects their response to cancer therapies, suggesting that understanding CAF plasticity can help develop better treatment strategies.

Article Synopsis
  • - The ESMO Clinical Practice Guidelines for oncogene-addicted metastatic non-small-cell lung cancer (mNSCLC) were updated into Pan-Asian adapted (PAGA) guidelines to better address the needs of Asian patients.
  • - A panel of experts from multiple Asian oncological societies collaborated to create these guidelines, focusing on scientific evidence rather than local treatment practices or drug availability.
  • - The guidelines aim to standardize the management of oncogene-addicted mNSCLC across Asia, while acknowledging regional differences in screening, treatment resources, and drug reimbursement policies.
