Obesity-mediated inflammation represents a key connection between the intake of foods with high inflammatory potential and colorectal cancer (CRC) risk. We aimed to explore the association between energy-adjusted dietary inflammatory index (E-DII) in relation to CRC risk in both obese and non-obese subjects. This study included 99 histopathologically confirmed CRC cases, 73 colonic polyps cases, and 141 healthy controls from tertiary medical centres in both urban and suburban areas in Peninsular Malaysia. The subjects were categorised into body mass index (BMI) < 25 kg/m² and BMI ≥ 25 kg/m² groups. E-DII scores were computed based on dietary intake assessed using a validated food frequency questionnaire (FFQ). Logistic regression models were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for potential cofounders. The mean dietary energy intake and mean BMI values of the subjects tended to increase as the E-DII scores increased (p for trend < 0.001). E-DII was significantly related to CRC risk only in obese subjects (OR = 1.45; 95% CI = 1.30–1.77; p < 0.001 for trend). Stratified analyses of risk factors showed significant associations between E-DII and CRC risk by age group (p for interaction = 0.030), smoking status (p for interaction = 0.043), and anthropometric indices for both males and females (p for interaction < 0.001) in the most pro-inflammatory E-DII quartile vs. the lowest E-DII quartile. Overall, pro-inflammatory diets were associated with an increased incidence of CRC in the Malaysian population, particularly in obese subjects.

Endometriosis affects approximately 6 to 10% of reproductive-age women globally. Despite much effort invested, the pathogenesis that promotes the development, as well as the progression of this chronic inflammatory disease, is poorly understood. The imbalance in the microbiome or dysbiosis has been implicated in a variety of human diseases, especially the gut microbiome. In the case of endometriosis, emerging evidence suggests that there may be urogenital-gastrointestinal crosstalk that leads to the development of endometriosis. Researchers may now exploit important information from microbiome studies to design endometriosis treatment strategies and disease biomarkers with the use of advanced molecular technologies and increased computational capacity. Future studies into the functional profile of the microbiome would greatly assist in the development of microbiome-based therapies to alleviate endometriosis symptoms and improve the quality of life of women suffering from endometriosis.

As the number of infections and deaths attributable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection continues to rise, it is now becoming apparent that the health impacts of the Coronavirus disease (COVID-19) may not be limited to infection and the subsequent resolution of symptoms. Reports have shown that patients with SARS-CoV-2 infection may experience multiple symptoms across different organ systems that are associated with adverse health outcomes and develop new cardiac, renal, respiratory, musculoskeletal, and nervous conditions, a condition known as Long COVID or the post-acute sequelae of COVID-19 (PASC). This review provides insights into distinct subphenotypes of Long COVID and identifies microbiota dysbiosis as a common theme and crucial target for future therapies. Another important finding is that Long COVID is associated with prolonged and increased inflammation, potentially attributable to immune system dysfunction. A promising solution lies in the potential of probiotics to mitigate Long COVID symptoms by restoring gut microbiota balance and modulating the immune response. By evaluating the current clinical development landscape of the use of probiotics to treat Long COVID symptoms, this paper provides recommendations for future research by stressing the need to understand the modulation of bacterium strains followed by probiotic therapy to understand the association of microbiota dysbiosis with Long COVID symptoms. This will facilitate the development of effective probiotic formulations that could serve as reliable therapies against Long COVID.

Ulcerative colitis (UC) is a chronic disease marked by mucosal inflammation of the colon, and its prevalence has progressively increased worldwide. Gut dysbiosis is recognized as a key contributor to its pathogenesis. Although conventional treatments are effective in managing symptoms, they often fail to address the underlying gut microbial imbalance, prompting growing interest in microbiota-based therapies. Probiotic supplementation has demonstrated potential to modulate the disease. However, its clinical application is limited by variability in formulations and strain composition. Debate persists regarding the relative benefits of single-strain probiotics (SSPs), which depend on strain specificity, versus multi-strain probiotics (MSPs), which may provide synergistic effects. The literature remains inconclusive, with some studies indicating that MSPs outperform SSPs, while others emphasize the importance of strain specificity. This review describes the mechanistic basis of both approaches and descriptively synthesizes their clinical efficacy in UC management based on the clinical studies published between 2018 and 2025. Several studies report that both SSPs and MSPs are associated with clinical improvements, including reduced disease activity, symptom alleviation, and enhanced endoscopic outcomes. Given the methodological heterogeneity across included studies, comparative findings should be interpreted with appropriate caution. A direct head-to-head trial could provide a better understanding to determine the optimal approach. Advancing toward personalized probiotic therapy may further enhance the clinical application of probiotics for disease management.

Background: Quality of life (QoL) is a crucial outcome measure in cancer care. This study aimed to identify the association of health-related quality of life (HRQoL) among colorectal cancer (CRC) patients in Malaysia. Methods: The study was conducted from January 2021 to July 2022, recruiting CRC patients from two teaching hospitals in Malaysia. The validated Malay versions of EORTC QLQ-C30 and QLQ-CR29 questionnaires assessed physical, psychological, and social functioning. Patients were evaluated 6 months after diagnosis to determine QoL associations. Anthropometric measurements were recorded at baseline (diagnosis, 0 months) and at follow-up (6 months). Results: Among 87 CRC patients (55.2% male, mean age 59.8 ± 11.8 years), 37.9% had stage III disease and 13.8% had stage IV. Most patients (93%) underwent surgery and 78% received chemotherapy. The mean global health status score was 66.57 ± 20.75. Multiple linear regression analysis revealed that older age (p = 0.03), advanced cancer stage (p = 0.017), lower body weight (p = 0.017), and reduced hip circumference (p = 0.040) are significantly associated with poorer global health status quality of life (GHS QoL). Nutritional parameters specifically predicted functional domains: lower body weight and BMI predicted role and cognitive function, while lower hip circumference predicted emotional function. Conclusions: Advanced age, disease stage, and nutritional status are significant associations of QoL in Malaysian CRC patients. These findings highlight the importance of nutritional assessment and intervention in CRC survivorship care to optimize patient outcomes.
