Construction and verification of a histone deacetylases-related prognostic signature model for colon cancer

Histone deacetylases (HDACs) contribute significantly to the initiation, progression, and prognosis of colorectal adenocarcinoma (COAD). Additionally, HDACs regulate the tumor microenvironment, immune escape, and tumor stem cells, and are closely linked to COAD prognosis. We developed a prognostic model for COAD that incorporates HDACs to evaluate their specific roles. The COAD dataset containing clinical and mutation data was collected using the TCGA and GEO databases to obtain genes associated with HDAC. LASSO analysis and univariate and multivariate Cox regression analysis were used to determine the presence of prognostic genes. Multivariate Cox analysis was also used to determine risk scores for HDAC-related features. Furthermore, genomic alterations, immune infiltration, and drug response were compared between high- and low-risk groups. Cellular experiments validated the potential regulatory role of BRD3 on COAD proliferation, migration, and apoptosis. The median risk scores, calculated based on the characteristics, demonstrated a more significant prognostic improvement in patients in the low-risk group. Furthermore, HDAC-related features were identified as important independent prognostic factors for patients with COAD. Additionally, genomic mutation status, immune infiltration, and function, as well as response to immunotherapy and chemotherapy, were found to be associated with risk scores. Subgroup analyses indicate that anti-PD-1 therapy may be beneficial for patients in the low-risk group. Additionally, a decrease in risk score was associated with a decrease in immune infiltration. Finally, HCT116 and HT29 cells exhibited inhibition of BRD3 gene proliferation and migration, as well as promotion of apoptosis. In patients with COAD, HDAC-related characteristics may be useful in predicting survival and selecting treatment.

Laboratuvarlar Tarafından Reddedilen Hasta Numunelerinin Kök Neden Analizi: 21 Adım Uygulaması Örneği

Aim: Root cause analysis is widely used in healthcare services to analyze the causes of near misses and adverse events with a systematic approach. This study, it is aimed to determine the root causes of rejected samples, define corrective/preventive actions, and create an action plan that will help the implementation of the suggested remedial actions and evaluate their effectiveness.
 Material and Methods: For the 21-step methodology, observation, interview, document and record review techniques were applied. The steps of the process were visualized with the flowchart technique and the reasons for rejected samples were analyzed with team members. The identified causes were visualized with the Fishbone Diagram technique, and the risk reduction strategies and improvement actions for rejected samples were determined by the Failure Mode Effect Analysis (FMEA) method. The Action Hierarchy tool was used to evaluate the power of improvement actions.
 Results: The root causes of rejected samples were identified as inadequate orientation and training practices, lack of applicability of policies and procedures, lack of monitoring and evaluation, inefficient process flow and lack of equipment. A total of 11 improvement actions were determined and planned for these root causes. It was predicted that there will be an approximately 64.5% decrease in risk scores in general with the basic measures presented in the performed FMEA.
 Conclusion: Overall, it was found that the 21-step methodology is suitable for determining root causes by offering detailed guidance.

Prediction of Coronary Artery Calcium in Young Adults Using the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) Risk Score

Using data from autopsied young people aged 15 to 34 years, the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) study developed a risk score based on age, sex, smoking status, high-density lipoprotein and non-high-density lipoprotein cholesterol levels, and the presence of obesity, hyperglycemia, and hypertension to predict advanced coronary artery atherosclerosis. The Coronary Artery Risk Development in Young Adults (CARDIA) study assessed coronary artery calcium (CAC) by computed tomography in young adults participating in the 15-year examination. The PDAY risk score was calculated from risk factors measured at the CARDIA examinations at years 0, 5, 10, and 15. Odds ratios for amount of CAC (6 ordinal categories) for a 1-point increase in risk score computed from the modifiable risk factors ranged from 1.10 to 1.16 (all statistically significant). Odds ratios for presence of any amount of CAC ranged from 1.09 to 1.15 (all statistically significant), with the highest odds ratio for the risk score at year 0. An increase in risk score between years 0 and 15 increased the odds of CAC, and a decrease in risk score decreased the odds of CAC. A positive family history of cardiovascular disease increased the odds of CAC. The c statistics ranged from 0.752 to 0.770, with the highest discrimination based on the year 0 revised PDAY risk score that included family history and increased the points for the sex differential. The PDAY risk score predicts CAC up to 15 years before its assessment, and risk score change during 15 years affects the risk of CAC.

Comparing environmental issues in Cuba before and after the Special Period: Balancing sustainable development and survival

Following the Earth Summit in 1992, Cuba designed and implemented a variety of programs, administrative structures, and public awareness activities to promote sound environmental management and sustainable development. This came shortly after the fall of the Soviet Union and the strengthening of the US blockade in 1990, which resulted in a 35% drop in Cuban GDP. This period, referred to as the Special Period, witnessed a decrease in many environmentally damaging activities both by choice and by necessity, but also resulted in many decisions to resuscitate the Cuban economy. The purpose of this work was to compare and rank the environmental risks Cuba faced before and during the Special Period (1990–2000) using two Comparative environmental risk assessments (CERAs). To do so, an ecosystem integrity risk assessment matrix was constructed with 42 risk end points. The matrix assessed the risk posed by 17 problem areas including air pollution, water contamination, solid waste sites, pesticides and ecosystem degradation. The risks were calculated using five criteria: area affected, vulnerability of affected population, severity of impact, irreversibility of effect and uncertainty. To construct this matrix, both literature reviews and expert interviews in Cuba were conducted in 2000. The results showed a general decrease in risk scores during the Special Period. Before the Special Period, high risks were posed by: terrestrial degradation and industrial wastewater and sludge, followed by freshwater degradation, surface water stressors, and pesticides. After the Special Period, industrial wastewater and sludge and pesticides were no longer high-risk areas, but municipal wastewater and marine coastal degradation ranked higher than previously. Also, the risk endpoints most stressed after 1990 were affected by activities controlled by the government, such as mining and tourism, and lack of infrastructure. Therefore, the claims that public environmental education is the main pathway to sustainable development in Cuba seem uninformed and other management practices should be evaluated.

Looks can be deceiving: Using a risk assessment instrument to evaluate the out-comes of child protection services

This study explores the use of a risk assessment instrument based on the Illinois CANTS-17B in the child protection services division of a large urban public social services agency. It addresses the usefulness of the instrument as an outcome measure tool, that is, as means of measuring successful case outcomes based on reductions in maltreatment risk between case opening and case closing. Two separate studies were conducted in which the initial and closing risk levels on the 14-item scale were compared. Results were highly statistically significant in both studies, with the difference being in the expected and desired direction: a decrease in risk scores at case closing. However, a more detailed exploration of the data and of the practice issues involved in the agency setting strongly suggests that these differences are largely due to the artificial inflation of initial risk scores by caseworkers in order to ensure children's acceptance for ongoing child protection services. These factors are discussed in detail, along with the policy decisions that ensued from the study.
