For many measurands, physicians depend on population-based reference intervals (popRI), when assessing laboratory test results. The availability of personalized reference intervals (prRI) may provide a means to improve the interpretation of laboratory test results for an individual. prRI can be calculated using estimates of biological and analytical variation and previous test results obtained in a steady-state situation. In this study, we aim to outline statistical approaches and considerations required when establishing and implementing prRI in clinical practice. Data quality assessment, including analysis for outliers and trends, is required prior to using previous test results to estimate the homeostatic set point. To calculate the prRI limits, two different statistical models based on 'prediction intervals' can be applied. The first model utilizes estimates of 'within-person biological variation' which are based on an individual's own data. This model requires a minimum of five previous test results to generate the prRI. The second model is based on estimates of 'within-subject biological variation', which represents an average estimate for a population and can be found, for most measurands, in the EFLM Biological Variation Database. This model can be applied also when there are lower numbers of previous test results available. The prRI offers physicians the opportunity to improve interpretation of individuals' test results, though studies are required to demonstrate if using prRI leads to better clinical outcomes. We recommend that both popRIs and prRIs are included in laboratory reports to aid in evaluating laboratory test results in the follow-up of patients.Despite advancements in treatments, oral squamous cell carcinoma (OSCC) has not significantly improved in prognosis or survival rate primarily due to the presence of treatment-resistant OSCC. The intercellular communication between tumour cells is a molecular mechanism involved in acquiring OSCC treatment resistance. Extracellular vesicles (EVs) and encapsulated miRNAs are important mediators of intercellular communication. Here, we focused on EVs released from clinically relevant radioresistant (CRR) OSCC cells. Additionally, we evaluated the correlation between miRNA expression in the serum samples of patients who showed resistance to radiotherapy and in EVs released from CRR OSCC cells. We found that EVs released from CRR OSCC cells conferred radioresistance to radiosensitive OSCC cells via miR-503-3p contained in EVs. This miR-503-3p inhibited BAK and impaired the caspase cascade to suppress radiation-induced apoptosis. Furthermore, OSCC cells with BAK knockdown had increased radioresistance. Additionally, the expression of circulating miR-503-3p in patients with OSCC was correlated with a poor treatment response and prognosis of radiotherapy. Our results provide new insights into the relationship between EVs and the radioresistance of OSCC and suggest that the miR-503-3p-BAK axis may be a therapeutic target and that circulating miR-503-3p is a useful prognostic biomarker in the radiotherapy of OSCC.

Hong Kong's existing mental health services are inadequate in addressing young people's needs. The LevelMind@JC project established an early intervention platform of community-based youth-specific mental health centres involving youth workers, cross-disciplinary professionals, and young people. The project intends to (1) pilot a community platform that incorporates a youth-friendly early screening tool with preventative intervention capabilities, (2) set up a state-of-the-art training system for youth mental health workers, (3) establish a community clinical support team and (4) develop a timely evaluation system to monitor the service and evaluate its outcome and cost-effectiveness against generic youth services.

Six hundred LevelMind@JC service users will be assessed alongside 600 young people visiting generic youth centres and 100 young people in the community. read more Participants will be matched according to age, gender, years of education, socioeconomic status, and level of distress. Assessments, administercost-effectiveness are established, the project could be scaled up, implicating a wider reach of care. We anticipate its success to be critical in combatting mental health issues stemming from both personal and population-level stressors.

Clinical trials have demonstrated efficacy of proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) in reducing risk of cardiovascular disease events, but effectiveness in routine clinical care has not been well-studied. We used negative control outcomes to assess potential confounding in an observational study of PCSK9i versus ezetimibe or high-intensity statin.

Using commercial claims, we identified U.S. adults initiating PCSK9i, ezetimibe, or high-intensity statin in 2015-2018, with other lipid-lowering therapy (LLT) use in the year prior (LLT cohort) or atherosclerotic cardiovascular disease (ASCVD) in the past 90 days (ASCVD cohort). We compared initiators of PCSK9i to ezetimibe and high-intensity statin by estimating one-year risks of negative control outcomes influenced by frailty or health-seeking behaviors. Inverse probability of treatment and censoring weighted estimators of risk differences (RDs) were used to evaluate residual confounding after controlling for covariates.

PCSK9i i effectiveness.Separation plays a critical role in a broad range of industrial applications. Developing advanced separation materials is of great significance for the future development of separation technology. Collagen fibers (CFs), the typical structural proteins, exhibit unique structural hierarchy, amphiphilic wettability and versatile chemical reactivity. These distinctive proprieties provided us infinite possibilities for the rational design of advanced separation materials. During the past two decades, we have already witnessed many progressive achievements in the development of CFs-derived advanced separation materials. Herein, we focused on the CFs-based separation materials and reviewed the recent progresses in this topic. CFs widely existing in animal skins display unique hierarchically fibrous structure, amphiphilicity-enabled surface wetting behaviors, multi-functionality guaranteed covalent/non-covalent reaction versatility. These outstanding merits of CFs bring great opportunities for realizing rational design of a variety of advanced separation materials that were capable of achieving high-performance separations to diverse specific targets, including oily pollutants, natural products, metal ions, anionic contaminants and proteins, etc. Besides, we also discussed the important issues for the further development of CFs-based advanced separation materials.

High glucose-induced trained immunity is a possible key player in "metabolic memory" among patients with diabetes. Increased aerobic glycolysis plays an important role in inducing trained immunity in diabetes.

Recently, multiple epidemiological studies have linked imatinib with the alteration of renal function in chronic myeloid leukaemia (CML) patients. This meta-analysis aimed to summarize the impact of imatinib use on renal function in CML patients.

A systematic search was conducted on MEDLINE and Embase to identify articles assessing the impact of imatinib exposure on renal function in CML patients. The risk of bias was assessed using the Newcastle-Ottawa scale (NOS). Two authors independently performed literature-screening, risk of bias and data extraction. The risk of renal dysfunction (chronic kidney disease or acute kidney injury) among imatinib users was computed as the primary outcome of interest. The certainty of findings was assessed using the grading of recommendations assessment, development and evaluation (GRADE) criteria.

A total of nine articles qualified for inclusion in the systematic review, of which four articles were eligible for meta-analysis. Based on the scoring on NOS, majority of the included studies were found to be of moderate risk of bias. Majority of the studies (n=6) reported significantly (p < .05) decrease in estimated glomerular filtration rate (eGFR) after imatinib treatment. The risk of developing renal dysfunction (chronic kidney disease or acute kidney injury) was found to be significantly higher in imatinib users as compared to other tyrosine kinase inhibitor (TKI) users with a pooled relative risk of 2.70 (95% CI 1.49-4.91). Sensitivity analysis also revealed a consistently high risk of renal dysfunction with imatinib use. GRADE criteria revealed low certainty of evidence.

This meta-analysis found an increased risk of renal dysfunction in imatinib users compared to other TKI users.

This meta-analysis found an increased risk of renal dysfunction in imatinib users compared to other TKI users.Atopic dermatitis (AD) is frequently misdiagnosed and undertreated, resulting in increased morbidity. In 2019, the Atopic Dermatitis Quality of Care Initiative was launched globally to investigate barriers to AD care and note good practice interventions to improve care. The initiative included a literature review to define the challenges in AD and a survey of 32 AD centers to define good practice interventions. One topic studied was best practices for clinical assessment and diagnosis. The literature review revealed the primary gaps included difficulty differentiating AD from other skin disorders, diagnosing atypical AD, staging AD severity in individual patients, and delays in assessment and treatment due to referral time lag. The best clinical practices used by leading AD centers included the use of validated diagnostic criteria, established AD scoring tools including patient-reported outcome measures and electronic health records (EHR), the formation of multidisciplinary teams (MDTs), and improved communication between health care providers (HCPs) and patients. Most centers worked with patient advocacy groups and implemented educational programs for HCPs. AD centers are overcoming issues in AD care. Educating health care providers and the public, using screening surveys, using established guidelines, and communicating with MCTs and patients through EHRs are the most frequently used strategies.Osteoarthritis (OA) is a common degenerative joint disease. The pathological changes of chondrocytes involve oxidative stress, the pro-inflammatory response, and pro-apoptotic events. Galectin-3 (Gal-3) is a 35 kDa protein with a special chimeric structure. Gal-3 participates in the progression of many diseases, such as cancer metastasis and heart failure. A previous study demonstrated that Gal-3 expression in human cartilage with OA is increased. However, the role of Gal-3 in chondrocyte dysfunction in joints is still unclear. In this study, we applied Gal-3 (5-20 μg/ml) to TC28a2 human chondrocyte cells for 24 h to induce chondrocyte dysfunction. We found that Gal-3 upregulated TLR-4 and MyD88 expression and NADPH oxidase, thereby increasing intracellular ROS in the chondrocytes. Gal-3 increased phosphorylated MEK1/2 and ERK levels, and promoted NF-κB activity. This activation of NF-κB was reduced by silencing TLR-4 and NOX-2. In addition, Gal-3 caused apoptosis of chondrocytes through the mitochondrial-dependent pathway via the TLR-4/NADPH oxidase/MAPK axis.
