This study aimed to objectively select the most appropriate clustering method and number of clusters for describing dietary patterns using a stability-based methodology. Cluster analysis was performed on dietary data from the NESCAV study using K-means and principal component analysis (PCA). The most stable solution was obtained using K-means clustering with three clusters. This identified three main dietary patterns in the population: a "Convenient" and "Non-Prudent" pattern associated with higher cardiovascular risk, and a "Prudent" pattern associated with decreased risk.

Value of Transferability and Efficiency in HTA
1) The document proposes using value of information (VOI) analysis to calculate the value of transferability (of results from a multinational trial to a specific country) in terms of expected value of sample information (EVSI).
2) It applies this method to results from the Scandinavian Simvastatin Survival Study, defining the posterior distribution of country results given the multinational trial results.
3) The value of transferability is measured as the difference between the prior and posterior expected value of perfect information (EVPI) for each country, indicating whether the multinational trial results reduce or increase uncertainty for reimbursement decisions.

This document discusses a study analyzing the cost effectiveness and cost utility of treating lumbar disc herniation through conservative or surgical methods. The study finds that while conservative treatment has a slightly lower initial cost, surgical treatment via microdiscectomy leads to significantly better quality of life outcomes when measured over longer time periods of one to five years. Specifically, microdiscectomy groups saw greater quality results compared to conservatively treated groups. The document concludes that conservative treatment is barely cost effective and economically disadvantageous when quality of life measures are considered, as surgical patients can resolve symptoms and return to daily activities more quickly, increasing productivity and quality adjusted life years gained.
A Comparison of Three EQ-5D Value sets
This document compares three EQ-5D value sets: the original EQ-5D-3L value set from the UK, a crosswalk value set mapping EQ-5D-5L states to the 3L, and a new native EQ-5D-5L value set for England. It finds that the 5L value set results in fewer health states valued as worse than dead, higher valuations overall, and greater impact of anxiety/depression. The 5L distribution of values is smoother compared to the 3L. The choice of value set may influence cost-effectiveness results, particularly for interventions targeting poor health.

This systematic review examined the effects of yoga on chronic low back pain. It analyzed data from 17 studies that met criteria for inclusion. The review found that yoga was associated with reductions in patient-reported pain scores over various time periods. Specifically, yoga was linked to a 38.3% reduction in pain scores after 1-2 weeks, up to a 56.2% reduction after 24-26 weeks. While the evidence was mixed in quality, the studies consistently showed yoga reducing pain scores according to an exponential decay model over time. More high-quality research is still needed to better understand yoga's long-term impact on chronic low back pain.
The cost-effectiveness of providing DAFNE to subgroups of predicted responders
This study aimed to predict patient responses to the DAFNE diabetes education program based on baseline characteristics and assess the cost-effectiveness of providing DAFNE only to predicted responders. Regression models found baseline HbA1c, fear of hypoglycemia, thoughts on diabetes seriousness, BMI, and gender predictive of HbA1c change after DAFNE. However, integrating these models into an economic simulation found providing DAFNE only to predicted responders generated fewer health benefits at higher costs than current practice, making it not a cost-effective approach.
Dietary Strategies for Weight Loss Maintenance
Weight regain after a successful weight loss intervention is very common. Most studies
show that, on average, the weight loss attained during a weight loss intervention period is not
or is not fully maintained during follow-up. We review what is currently known about dietary
strategies for weight loss maintenance, focusing on nutrient composition by means of a systematic
review and meta-analysis of studies and discuss other potential strategies that have not been studied
so far. Twenty-one studies with 2875 participants who were overweight or obese are included in
this systematic review and meta-analysis

A Arnold_Weighing Results Abstract_Spring 2013
Worksite weight management programs in the U.S. were systematically reviewed. 10 study arms within 7 studies were assessed to see if participants lost weight and to compare program components between effective and ineffective interventions. 70% of interventions favored weight loss, but only 50% showed significant weight loss. Effective programs incorporated behavioral treatment theories like social cognitive theory and planned behavior theory. They also included internal support, incentives, consultations, journaling, physician monitoring, and stress management. Overall evidence for workplace weight loss programs in the U.S. was inconclusive due to limited qualifying studies.

This study analyzed the cost of drug prescriptions for treating reactive airways disease (RAD) in children at an outpatient pediatric clinic in Northern India over one year. A total of 332 children were diagnosed with RAD. Bronchodilators and steroids were the most commonly prescribed drug classes, with steroids accounting for half of the total drug costs. The results provide insight into the cost burden of RAD treatment in India and which drug classes contribute most to costs. However, the study had a small sample size and increasing the sample size in future studies is recommended to consolidate the findings.Measurable Impacts of the “Principles of Organic Agriculture”

- The study systematically reviewed physical activity interventions for adolescent cancer patients and survivors. Four controlled trials involving physical activity during or after cancer treatment were identified.
- The limited evidence available suggests physical activity is safe for adolescent cancer patients, but more high-quality studies are needed to determine effectiveness on health outcomes due to few existing studies.
- Future research should investigate optimal timing, settings, durations and intensities of physical activity interventions as well as potential moderating factors like age, gender and cancer type.

This study aimed to develop a predictive model for the costs and life expectancy of patients with diffuse large B-cell lymphoma (DLBCL) in the UK. The study used a discrete event simulation model based on data from 4880 DLBCL patients. The model predicted 5-year and lifetime medical costs and survival for patients based on their characteristics, treatment responses, and costs derived from the data. The results were validated against empirical data and literature. Younger patients had higher costs but better survival, while treatment provided higher costs and longer survival than no treatment. Total annual costs of treating DLBCL in the UK were estimated to be £95-99 million.
A real life example to show the added value of the Phenotype Database (dbNP)....
NuGO has initiated the development of the Phenotype Database (dbNP). This database is developed together with several other consortia (e.g. Netherlands Metabolomics Centre) and is currently used within several European projects, such as Food4me, NU-AGE, Bioclaims and Nutritech.
The Phenotype Database (www.dbnp.org) is a web-based application/database that can store any biological study. We used this application to perform an analysis on a combination of several studies with the objective to test if it is possible to answer new research questions using a ‘virtual cohort’.
Study comparison:
The assessment of the health status of an individual is an important but challenging issue. Nowadays, challenge tests are proposed as a method to assess and quantify health status. We would like to find mechanistic explanations for differences in clinical subgroups and to develop a metabolomics platform based fingerprint at baseline that represents important parameters of the challenge test. Currently, there is not one single study available that includes enough subjects from specific clinical subgroups to develop such a fingerprint or study the biological processes specific for those subgroups. Therefore, we developed a toolbox that facilitates the combined analysis of multiples studies.

Interns explain the predominance of variation in laboratory utilization on two subspecialty services. As the supervision increases to the more acute setting of the Medical Intensive Care Unit, more of the explanation is shared among the providers on the team. The study found that interns had the predominant impact on variations in laboratory utilization on the general medicine service, while in more acute settings like the MICU, attending physicians and residents also contributed to variations. Limitations include this being a single-center study that did not link variations in laboratory utilization to patient outcomes.Clinimetrias seminario

2. In the TICORA study, patients who received intensive therapy based on outcome measures achieved better results and a higher rate of remission than those on routine care.
3. Later studies like GUEUPARD and SWEFOT found that initial combination therapy may be more effective early on, but that the benefits diminished after 1-2 years, with most patients in both groups achieving low disease activity.

Crimson Publishers-Allometry Scalling in Drug Development
Allometry scaling is used to predict pharmacokinetic parameters such as volume of distribution, clearance, and half-life in humans based on animal data. It involves plotting parameters against body weight on a log-log scale to determine relationships. Two approaches for interspecies scaling are physiological models using organ sizes and rates, and empirical allometric methods. Accurate prediction requires data from multiple animal species, though some use fewer. The goal of allometric scaling is to safely estimate first human doses during drug development.

Abstract E9911
This study compared the effectiveness of different taxane chemotherapy regimens as adjuvant breast cancer treatment in patients with node-positive or high-risk node-negative breast cancer. Nearly 5000 patients received doxorubicin and cyclophosphamide followed by one of four taxane regimens: paclitaxel or docetaxel given every three weeks or weekly. There was no significant difference in disease-free survival between taxane types or dosing schedules. However, there was a trend toward improved disease-free survival for weekly paclitaxel compared to standard paclitaxel given every three weeks. Overall toxicity was similar across the four treatment arms.

Biostatistics and its importance to Biologist
Biostatistics is the application of statistics to biological and medical fields. It involves collecting and analyzing data from experiments and studies. Biostatisticians help design clinical trials and epidemiological studies to investigate diseases. They use statistical methods and software to interpret data, make valid inferences, and solve public health problems. Biostatistics is important in areas like genetics, pharmacology, and demography. It helps evaluate public health programs and policies. While powerful, biostatistics has limitations like being dependent on quality data collection and potential for errors in results or decisions.

Though the inevitable outcome of Systems Biology (SB) may be directed to seek answers to the medical problems; however, due to its expanding horizon and flexibility, different academic institutions across the globe focus on different aspects of SB in their educational curriculum. Hence, some European educationists propose for stream lining of different course curriculum. Here such issues are discussed with respect to their translation towards medicine and health care system i.e., Systems Medicine (SM) under the perspectives of developing countries.Clinical Prediction Rules
This document discusses clinical prediction rules (CPRs), which are decision tools used by clinicians to predict outcomes. It covers the development, validation, and functions of CPRs. Specifically, it outlines 8 standards for developing a CPR, including clearly defining outcomes and predictors, ensuring reliability of predictors, having an adequate sample size, and accurately measuring a CPR's performance. An example CPR for ankle fractures is used to illustrate the development process. The document emphasizes the importance of prospectively validating CPRs in new populations before implementation, to assess their accuracy outside the initial study.

1. Cross-sectional studies measure exposures and outcomes in a population at a single point in time and are commonly used to estimate disease prevalence and describe population characteristics.
2. They can provide clues about associations but cannot determine causation due to their observational nature.
3. Planning is important for cross-sectional studies including clear objectives, sampling, data collection methods, and analysis of results with descriptive statistics.

Abstract
We report a web-based tool for analysis of experiments using indirect calorimetry to measure physiological energy balance. CalR simplifies the process to import raw data files, generate plots, and determine the most appropriate statistical tests for interpretation. Analysis using the generalized linear model (which includes ANOVA and ANCOVA) allows for flexibility in interpreting diverse experimental designs, including those of obesity and thermogenesis. Users also may produce standardized output files for an experiment that can be shared and subsequently re-evaluated using CalR. This framework will provide the transparency necessary to enhance consistency, rigor, and reproducibility. The CalR analysis software will greatly increase the speed and efficiency with which metabolic experiments can be organized, analyzed per accepted norms, and reproduced and has become a standard tool for the field. CalR is accessible at https://CalRapp.org/
The top 4 key questions that our tool can answer:
1. Can I reproducibly and transparently analyze indirect calorimetry experiments in under 10 minutes?
2. How hard is it to use Analysis of Covariance (ANCOVA) to determine whether my groups of animals are significantly different?
3. Is there an automated, reproducible way to exclude “noisy” outlier data from our indirect calorimetry experiments?
4. What are the key factors in determining metabolic rate of mice?

A Community Trial in Coastal Karnataka using Life Style Modifications to Asse...
1) A community trial was conducted in 3 villages in coastal Karnataka, India to assess the impact of lifestyle modifications on hypertension and diabetes. 305 participants with hypertension and/or diabetes were randomly assigned to receive a comprehensive lifestyle modification module, physical activity module, or serve as controls.
2) The comprehensive module included dietary changes, exercise, and tobacco cessation advice, while the physical activity module focused only on exercise. Results showed the comprehensive module was more effective in controlling blood pressure and diabetes.
3) The study suggests similar community-based lifestyle modification models could help achieve treatment goals, improve medication adherence, and reduce burden on the healthcare system for non-communicable disease control. However, further research is needed to
Rachel Keller_ MWACSM poster Fall 2015(final)
This study examined the relationship between prescription medication usage, physical activity, functional capacity, and diet in older adults. 68 older adult subjects underwent physical activity assessments including a 6-minute walk test and tracking calories from moderate to vigorous physical activity. Subjects also completed 3-day dietary records which were analyzed for nutrient intake. The study found that prescription medication usage was inversely correlated with physical activity levels, functional capacity, and intake of polyunsaturated fats, meaning higher physical activity and functionality were associated with fewer medications, as was higher polyunsaturated fat intake. These results suggest prescription medication usage in older adults is associated with physical activity, functional ability, and diet.

Predicting Life Expectancy of Hepatitis B Patients
The goal of this project is to find the best tool for predicting the life expectancy of people with Hepatitis B. Different Machine Learning methods have been completely studied and various Machine Learning methods have been carried out by different experimenters. Hepatitis B is a worldwide disease with a high mortality rate. Different methods have been used by different researchers to predict the life expectancy of Hepatitis B patients. The Machine Learning models and algorithms such as the Classification model, Logistic Regression model, Recursive Feature Elimination Algorithm, Cirrhosis Mortality model, Extreme Gradient Boosting, Random Forest, Decision Tree have been utilized by different researchers to predict the life expectancy of Hepatitis B patients. Some algorithms and models showed very interesting and proving results whereas some were not that good. Area Under Curve analysis was used to assess the estimation of various models. The AUROC value of the PSO model was minimal, while the ADT model had the highest accuracy. XGBoost showed appropriate predictive performance. All other models showed good calibration.
Atlanta Classification.ppt
This document discusses modifying the Atlanta classification system for acute pancreatitis. It summarizes the history of classifications, limitations of the Atlanta system, and proposals for revisions. The Atlanta system only divides pancreatitis into mild and severe groups. The revised classification adds a third category - moderately severe acute pancreatitis (MSAP) - for patients with local complications but transient organ failure who require ICU care. The document presents results of a study validating the MSAP subgroup and comparing outcomes between mild, MSAP and severe pancreatitis. The study found MSAP to have higher morbidity than mild but lower mortality than severe pancreatitis.
Impactof en feeding protocols
This multicenter observational study evaluated the impact of enteral feeding protocols on nutrition delivery in critically ill patients. The study found that sites using a feeding protocol had better enteral nutrition adequacy, started enteral nutrition earlier, and had higher overall nutritional adequacy compared to sites without a protocol. Specifically, sites with a protocol achieved 45.4% enteral nutrition adequacy compared to 34.7% for sites without. The presence of a protocol was associated with a 4.1% increase in enteral nutrition adequacy after adjusting for patient and site characteristics. However, overall nutritional adequacy remained below targets, indicating need for further refinement of feeding protocols.

Machine Learning in Healthcare by Mehrdad Yazdani
Abstract:- Using Machine Learning to Identify Major Shifts in Human Gut MicrobiomeProtein Family Abundance in Disease Inflammatory Bowel Disease (IBD) is an autoimmune condition that is observed to be associated with major alterations in the gut microbiome taxonomic composition. Here we classify major changes in microbiome protein family abundances between healthy subjects and IBD patients. We use machine learning to analyze results obtained previously from computing relative abundance of ~10,000 KEGG orthologous protein families in the gut microbiome of a set of healthy individuals and IBD patients. We develop a machine learning pipeline, involving the Kolomogorv-Smirnov test, to identify the 100 most statistically significant entries in the KEGG database. Then we use these 100 as a training set for a Random Forest classifier to determine ~5% the KEGGs which are best at separating disease and healthy states. Lastly, we developed a Natural Language Processing classifier of the KEGG description files to predict KEGG relative over- or under- abundance. As we expand our analysis from 10,000 KEGG protein families to one million proteins identified in the gut microbiome, scalable methods for quickly identifying such anomalies between health and disease states will be increasingly valuable for biological interpretation of sequence data.

The document provides an introduction to the stepped wedge cluster randomized trial (SW-CRT) design for evaluating policy and service delivery interventions. It defines key features of the SW-CRT design, including that it allows sequential rollout of an intervention to clusters over time and ultimately all clusters receive the intervention. Examples of SW-CRTs are provided covering different areas like emergency laparotomy, depression management, and vaccination programs. Considerations for when the SW-CRT design is appropriate and potential variations are discussed.
The role of bowel preparation in colorectal surgery
This study analyzed data from over 27,000 patients in the American College of Surgeons National Surgical Quality Improvement Program database who underwent elective colorectal resection from 2012 to 2015. The study found that while mechanical bowel preparation alone did not reduce postoperative infections, the combination of mechanical and antibiotic bowel preparation resulted in significantly fewer surgical site infections and Clostridium difficile infections compared to no preparation or antibiotic preparation alone. The authors conclude that combined mechanical and antibiotic bowel preparation should be used for elective colorectal resections when possible due to its effectiveness in reducing infectious complications.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Stability based validation of dietary patterns obtained by cluster (1)
- 1. STABILITY-BASED VALIDATION OF DIETARY PATTERNS OBTAINED BY CLUSTER ANALYSIS
- 2. INTRODUCTION • Cluster analysis is a data-driven method used to create clusters of individuals sharing similar dietary habits. However, this method requires specific choices from the user which have an influence on the results. Therefore, there is a need of an objective methodology helping researchers in their decisions during cluster analysis. • The objective of this study was to use such a methodology based on stability of clustering solutions to select the most appropriate clustering method and number of clusters for describing dietary patterns in the NESCAV study (Nutrition, Environment and Cardiovascular Health), a large population-based cross-sectional study in the Greater Region (N = 2298).
- 3. METHODS • Transformation of the data. • Formalization of cluster analysis. • The measure of stability.
- 4. COMPARISON OF DIETARY PATTERNS OBTAINED WITH PCA AND K-MEANS
- 5. RESULTS AND FUTURE OUTCOMES • Distributions were described with box-plots and average values computed on 20 repetitions of the algorithm. Regardless of stability indices and number of clusters, more stable solutions were obtained with K-means. In addition, the most stable solution was obtained with 3 clusters. Therefore, dietary patterns were computed with K-means algorithm and a predefined number of clusters equal to three.
- 6. CONCLUSION • In summary, we used an objective methodology based on the stability of clustering solutions allowing selection of the most appropriate clustering method and number of cluster for describing dietary patterns in a population. Three main dietary patterns were identified in the Greater region. A “Convenient” and a “Non-Prudent” pattern associated with a higher cardiovascular risk and a “Prudent” pattern associated with a decreased cardiovascular risk.
