Objective: To investigate the prevalence and risk factors of psychological symptoms and quality of life (QoL) in early patients with inflammatory bowel disease (IBD).

Methods: From September 2021 to May 2022, a unified questionnaire was developed to collect clinical data from early patients with IBD from 42 tertiary care hospitals. The influencing factors of psychological symptoms and poor QoL are screened by logistic regression analysis for constructing model in predicting poor QoL.

The lack of clear definition and classification for "moderate ulcerative colitis (UC)" creates ambiguity regarding the suitability of step-up versus top-down treatment approaches. In this paper, experts address crucial gaps in assessing and managing moderate UC. The Asia-Pacific, Middle East, and Africa Inflammatory Bowel Disease Coalition comprised 24 experts who convened to share, discuss and vote electronically on management recommendations for moderate UC.

Article Synopsis
  • The study aims to identify risk factors for thrombotic events in obstetric antiphospholipid syndrome (OAPS) patients and create a predictive model specifically for postpartum thrombosis in those without previous thrombotic history.
  • A retrospective analysis was performed on 269 OAPS patients, evaluating various clinical and laboratory factors to determine which could best predict thrombosis risk, ultimately leading to the development of a nomogram.
  • Findings showed that 32.58% of retrospective patients developed thrombosis after three years, with key risk indicators being low platelet count, multiple positive antiphospholipid antibodies, and the use of specific post-delivery medications.

Article Synopsis
  • * In a study involving 14 Chinese patients with acute severe ulcerative colitis, all showed initial clinical response to 45 mg of upadacitinib after eight weeks, with a clinical remission rate of 28.6% and some improvement in endoscopic evaluations.
  • * While upadacitinib demonstrated short-term effectiveness and safety, with some adverse events noted, further research is necessary to assess its long-term effects for patients.

Article Synopsis
  • The study aimed to create a machine learning tool to identify IBD patients at a higher risk of impaired quality of life (QOL), enabling earlier intervention and better long-term outcomes.* -
  • Researchers collected data from 2478 IBD patients through an online questionnaire across multiple hospitals in China and developed eight machine learning models to predict QOL impairments.* -
  • The support vector machine (SVM) model was found to be the most effective, highlighting key risk factors such as glucocorticoid use and anxiety, which are linked to poorer QOL.*

Hepatocellular carcinoma (HCC) is a highly heterogeneous malignancy with high incidence, recurrence, and metastasis rates. The emergence of immunotherapy has improved the treatment of advanced HCC, but problems such as drug resistance and immune-related adverse events still exist in clinical practice. The immunosuppressive tumor microenvironment (TME) of HCC restricts the efficacy of immunotherapy and is essential for HCC progression and metastasis.

Despite the success of immunotherapy in treating hepatocellular carcinoma (HCC), HCC remains a severe threat to health. Here, a crucial transcription factor, SOX12, is revealed that induces the immunosuppression of liver tumor microenvironment. Overexpressing SOX12 in HCC syngeneic models increases intratumoral regulatory T-cell (Treg) infiltration, decreases CD8T-cell infiltration, and hastens HCC metastasis.

Article Synopsis
  • * Data was collected from over 1,000 patients with a follow-up period of about 5.3 years, indicating high usage of IBD treatments but a lower rate of surgeries compared to Western counterparts.
  • * Findings suggest that while treatment exposure is similar, the natural progression of UC in China differs from that in Western countries, highlighting the need for careful monitoring and further research to confirm these results due to potential biases in the study design.

Targeted therapy is crucial for advanced colorectal cancer (CRC) positive for genetic drivers. With advances in deep sequencing technology and new targeted drugs, existing standard molecular pathological detection systems and therapeutic strategies can no longer meet the requirements for careful management of patients with advanced CRC. Thus, rare genetic variations require diagnosis and targeted therapy in clinical practice.

Article Synopsis
  • The study investigates how gastroenterologists and gastrointestinal surgeons perceive and trust AI technologies used in colonoscopies, particularly for detecting and managing colorectal polyps.
  • Researchers conducted a web-based questionnaire with 165 participants across five Asia-Pacific regions to assess their demographics, AI usage intentions, and perceived risks and acceptance.
  • Findings indicate a strong interest in using AI for diagnosis among gastroenterologists, although there are varying levels of concern regarding its risks and acceptance in practice.*

The biophysical properties of the extracellular matrix (ECM) play a pivotal role in modulating cancer progression via cell-ECM interactions. However, the biophysical properties specific to gastric cancer (GC) remain largely unexplored. Pertinently, GC ECM shows significantly heterogeneous metamorphoses, such as matrix stiffening and intricate restructuring.

Objective: To explore the impact of common gastrointestinal (GI) symptoms on psychological symptoms, sleep quality, and quality of life in patients with inflammatory bowel disease (IBD).

Methods: A unified questionnaire was developed to collect clinical data on the mental psychology and quality of life of IBD patients from 42 hospitals in 22 provinces in P. R.

Taurine is used to bolster immunity, but its effects on antitumor immunity are unclear. Here, we report that cancer-related taurine consumption causes T cell exhaustion and tumor progression. The taurine transporter SLC6A6 is correlated with aggressiveness and poor outcomes in multiple cancers.

Background: Baseline serological biomarkers have the potential to predict the benefits of adjuvant chemotherapy in patients with gastric cancer. However, the fluctuating nature of postoperative recurrence risk makes precise treatment challenging. We aimed to develop a risk score in real-time predicting outcomes for postoperative GC patients using blood chemistry tests.

Background & Aims: Hepatocellular carcinoma (HCC) is characterized by an immune-suppressive microenvironment, which contributes to tumor progression, metastasis, and immunotherapy resistance. Identification of HCC-intrinsic factors regulating the immunosuppressive microenvironment is urgently needed. Here, we aimed to elucidate the role of SYR-Related High-Mobility Group Box 18 (SOX18) in inducing immunosuppression and to validate novel combination strategies for SOX18-mediated HCC progression and metastasis.

Background: Recurrence following radical resection in patients with stage IB gastric cancer (GC) is not uncommon. However, whether postoperative adjuvant chemotherapy could reduce the risk of recurrence in stage IB GC remains contentious.

Methods: We collected data on 2110 consecutive patients with pathologic stage IB (T1N1M0 or T2N0M0) GC who were admitted to 8 hospitals in China from 2009 to 2018.

Escherichia coli LF82 (LF82) is associated with Crohn's disease. The simplicity and genetic maneuverability of honeybees' gut microbiota make them suitable for studying host-microbe interactions. To understand the interaction between LF82 and host gut, LF82 was used to infect germ-free honeybees (Apis mellifera) orally.

Alternative splicing regulates gene expression and functional diversity and is often dysregulated in human cancers. Here, we discovered that the long noncoding RNA (lncRNA) MIR99AHG regulated alternative splicing to alter the activity of a chromatin remodeler and promote metastatic behaviors in colorectal cancer (CRC). MIR99AHG was abundant in invasive CRC cells and metastatic tumors from patients and promoted motility and invasion in cultured CRC cells.
