Personalized lifestyle medicine: relevance for nutrition and lifestyle recommendations

High-fat diet-negative impact on female fertility: from mechanisms to protective actions of antioxidant matrices

Introduction

Excessive calorie intake poses a significant threat to female fertility, leading to hormonal imbalances and reproductive challenges. Overconsumption of unhealthy fats exacerbates ovarian dysfunction, with an overproduction of reactive oxygen species causing oxidative stress, impairing ovarian follicle development and leading to irregular ovulation and premature ovarian failure. Interest in biological matrices with high antioxidant properties to combat diet-related oxidative stress has grown, as they contain various bioactive factors crucial for neutralizing free radicals potentially preventing female reproductive health. This systematic review evaluates the female reproductive impact of biological matrices in mitigating oxidative damages induced by over calory habits and, in particular, high fat diets.

Methods

A comparative approach among mammalian models was utilized to interpret literature available data. This approach specifically investigates the antioxidant mechanisms of biological matrices on early and late ovarian folliculogenesis, under physiological and hormone-induced female reproductive cycle. Adhering to the PRISMA 2020 guidelines, only English-language publications from peer-reviewed international indexes were considered.

Results

The analysis of 121 publications meeting the inclusion criteria facilitated the identification of crucial components of biological matrices. These components, including carbocyclic sugars, phytonutrients, organosulfur compounds, and vitamins, were evaluated for their impact on ovarian follicle resilience, oocyte quality, and reproductive lifespan. The detrimental effects of oxidative stress on female fertility, particularly exacerbated by high saturated fat diets, are well-documented. In vivo studies across mammalian preclinical models have underscored the potential of antioxidants derived from biological matrices to mitigate diet-induced conditions. These antioxidants enhance steroidogenesis and ovarian follicle development, thereby improving oocyte quality. Additionally, discussions within these publications emphasized the clinical significance of these biological matrices, translating research findings into practical applications for female health.

Conclusion

Further research is essential to fully exploit the potential of these matrices in enhancing female reproduction and mitigating the effects of diets rich in fatty acids. This requires intensified in vitro studies and comprehensive collection of in vivo data before clinical trials. The promotion of ovarian resilience offers promising avenues for enhancing understanding and advancing female reproductive health world-wide.

Lifestyle Medicine in Focus: A Cross-Sectional Study Comparing Domestic and International Students

This study investigated lifestyle factors among Hungarian and international students, utilizing lifestyle medicine principles to enhance overall well-being. Conducted at the University of Debrecen through a cross-sectional survey, we examined selected lifestyle factors, more specifically sleep patterns, weight management, nutrition, physical activity, mental well-being, and alcohol use. Hungarian (N = 122) and international (N = 139) students were compared, revealing significant differences. Hungarian students slept less (p = 0.041), desired weight loss (p = 0.040), ate more fruits and vegetables (p = 0.014), exercised longer (p = 0.002), and reported higher purpose and social support (p = 0.009), with higher alcohol use (p < 0.001). These findings highlight distinct experiences and challenges faced by these student groups including variations in sleep, weight management, diet, exercise, and social support. Targeted interventions and tailored support are essential to address their specific needs. To promote the well-being of both Hungarian and international students, educational programs addressing various facets of a healthy lifestyle are crucial. This study offers valuable insights into lifestyle factors and health outcomes among Hungarian and international students and underscores the importance of addressing the unique needs of each group through tailored interventions.

The underlying relationship between exercise and the prevalence of periodontitis: a systematic review and meta-analysis

BACKGROUND

Although exercise has been proposed as an effective intervention for various lifestyle-related diseases and pathological scenarios, few researches assessed the impact of taking exercise on the prevalence of periodontitis.

PURPOSE

This study aimed to perform a comprehensive literature review and meta-analysis from both observational and intervention studies to explore the relationship between exercise and periodontitis and to provide references for future intervention programs aimed at preventing periodontitis.

METHOD

A systematic literature search was conducted in PubMed/MEDLINE, Web of Science, Cochrane Library, and Scopus for peer-reviewed studies published in English From January 1993 to January 2023 according to the PRISMA guidelines. Articles were selected if subjects were human and studies evaluating the association between exercise and periodontitis.

RESULTS

4098 references were retrieved. After screening the results, 30 studies were selected. Of these, 20 studies indicated an inverse association between exercise and periodontitis, while the remaining 10 did not reach conclusive findings. The meta-analysis demonstrated a risk ratio of 0.84 (95%CI: 0.77, 0.91) between the active group and the inactive group (P < 0.01), which indicated an inverse relationship between exercise and periodontitis.

CONCLUSION

Overall, the increase in exercise presents an inverse association with the presence and severity of periodontitis. Accordingly, taking exercise might be a potential approach that contributes to improvements in periodontitis.

Impact of wearable device-based interventions with feedback for increasing daily walking activity and physical capacities in cardiovascular patients: a systematic review and meta-analysis of randomised controlled trials

OBJECTIVE

To systematically review randomised controlled trials (RCTs) using a wearable physical activity monitoring device as an intervention to increase daily walking activity and improve physical capacities in patients with cardiovascular disease (CVD).

DESIGN

Systematic review and meta-analysis of RCTs.

DATA SOURCES

PubMed, Embase and Web of Science from inception to June 2022.

ELIGIBILITY CRITERIA

Randomised controlled studies including patients with CVD over 18 years of age at the end of a cardiac rehabilitation programme comparing an intervention group using a wearable physical activity monitoring device with feedback with usual care or with a control group receiving no feedback on their physical activity and reporting a change in the daily number of steps and/or a change in the distance covered in the 6-minute walk test (6-MWT) or a change in peak oxygen uptake (V̇O2_peak) as endpoints.

RESULTS

Sixteen RCTs were included. The intervention of wearing a physical activity monitoring device with feedback significantly improved daily number of steps compared with controls (standardised mean difference (SMD) 0.85; 95% CI (0.42; 1.27); p<0.01). The effect was greater when the duration of the intervention was less than 3 months (SMD 1.0; 95% CI (0.18; 1.82); p<0.01) than when the duration of the intervention was 3 months or longer (SMD 0.71; 95% CI (0.27; 1.16); p<0.01), but no significant interaction was found between subgroups (p=0.55). 6-MWT distance and V̇O2_peak showed only small effects (SMD 0.34; 95% CI (-0.11; 0.80); p=0.02 and SMD 0.54; 95% CI (0.03; 1.03); p=0.07, respectively).

CONCLUSION

The use of wearable physical activity monitoring devices appears to help patients with CVD to increase their daily walking activity and thus their physical activity, particularly in the short term.

Eight qualitative and quantitative studies that fit the research question were included. The most frequently described barriers are systemic barriers that hinder comprehensive and equitable access to health care and medication, as well as a lack of educational programs, personalized interventions to improve adherence to treatments, and lifestyle changes. Economic factors are critical in Latin America, hindering access to the health system and changes to lifestyles due to the costs of transportation, medical appointments, and medicines.

Conclusions

The detected barriers affect all dimensions of adherence to treatment; among the most important barriers are decision makers who lack education and positioning with respect to care of hypertension.

Role, importance and assessment of dietary habits in urolithiasis patient

Urolithiasis, which prevalence is increasing, poses a risk for chronic kidney disease in patients. Dietary habits play a significant role in stone formation, growth and recurrence. Also, comorbidities and lifestyle changes are among the factors affecting stone formation. The next step should be to detect metabolic disorders, if any, with analyzes to be made after a detailed anamnesis, and to arrange the necessary treatment. Insufficient fluid intake is considered to be the main dietary risk factor for urolithiasis. A daily fluid intake of 2.5-3.0 L/day or diuresis of 2.0-2.5 L/day is recommended to prevent recurrence of kidney stones. Not all beverages are beneficial, and some may even increase the risk of stone formation. Dietary management, vitamins and supplements, physical activity are important components in reducing the risk of recurrent urolithiasis. A detailed dietary assessment is recommended as dietary habits affect the faith of the disease. In this review we evaluated the dietary approach of urolithiasis patients with and without comorbidities, the recommended daily fluid intake, vitamin supplementation, and relation of the urolithiasis with physical activity.

Predictive genomic tools in disease stratification and targeted prevention: a recent update in personalized therapy advancements

In the current era of medical revolution, genomic testing has guided the healthcare fraternity to develop predictive, preventive, and personalized medicine. Predictive screening involves sequencing a whole genome to comprehensively deliver patient care via enhanced diagnostic sensitivity and specific therapeutic targeting. The best example is the application of whole-exome sequencing when identifying aberrant fetuses with healthy karyotypes and chromosomal microarray analysis in complicated pregnancies. To fit into today's clinical practice needs, experimental system biology like genomic technologies, and system biology viz., the use of artificial intelligence and machine learning is required to be attuned to the development of preventive and personalized medicine. As diagnostic techniques are advancing, the selection of medical intervention can gradually be influenced by a person's genetic composition or the cellular profiling of the affected tissue. Clinical genetic practitioners can learn a lot about several conditions from their distinct facial traits. Current research indicates that in terms of diagnosing syndromes, facial analysis techniques are on par with those of qualified therapists. Employing deep learning and computer vision techniques, the face image assessment software DeepGestalt measures resemblances to numerous of disorders. Biomarkers are essential for diagnostic, prognostic, and selection systems for developing personalized medicine viz. DNA from chromosome 21 is counted in prenatal blood as part of the Down's syndrome biomarker screening. This review is based on a detailed analysis of the scientific literature via a vigilant approach to highlight the applicability of predictive diagnostics for the development of preventive, targeted, personalized medicine for clinical application in the framework of predictive, preventive, and personalized medicine (PPPM/3 PM). Additionally, targeted prevention has also been elaborated in terms of gene-environment interactions and next-generation DNA sequencing. The application of 3 PM has been highlighted by an in-depth analysis of cancer and cardiovascular diseases. The real-time challenges of genome sequencing and personalized medicine have also been discussed.

Supervised and Individualized Lifestyle Medicine Therapy of a Patient after Myocardial Infarction—Case Study

Background: In the rehabilitation of patients with cardiovascular disease (CVD) and after myocardial infarction (MI), lifestyle modifications—exercise and nutritional therapy, smoking cessation, stress management—are essential and have a major, long-term impact on the overall health of patients. Methods: After MI and acute primary care, a lifestyle medicine team (medical doctors, dietitian, exercise physiologist) supervised the therapy of a 40 year-old male patient for 12 months. The program included assessments, regular medical controls, personalized diet, and exercise therapy monitored by a heart rate watch. Results: Gradual and continuous weight loss, major reduction in medication and significant improvement in fitness level, blood glucose level, and cardiac function were measured after the program. Due to these positive changes, the patient’s overall health improved to an even better level than before his MI. Conclusion: The results of this program highlight the benefits and importance of the personalized therapy and the lifestyle medicine team approach in the rehabilitation of CVD patients. Individualized and supervised lifestyle therapy should be part of the primary hospital care of CVD patients lead by medical doctors and supported by other health care providers.

The association of sedentary behaviour and physical activity with periodontal disease in NHANES 2011-2012

AIM

Periodontal disease is one of the most prevalent oral pathologies and a major chronic disease worldwide. Lifestyle habits such as poor nutrition and smoking have been established to contribute to the development of periodontal disease, but limited research has investigated whether physical activity and sedentary lifestyle play a role. The purpose of this study is to evaluate the association between physical activity, sedentary behaviour, and periodontal disease.

MATERIALS AND METHODS

We used a nationally representative data set from the National Health and Nutrition Examination Survey (NHANES) 2011-2012. We examined the association between physical activity and sedentary behaviour and periodontal disease using multivariable logistic regression models and reported odds ratios (ORs).

RESULTS

Individuals with higher total physical activity, higher leisure time physical activity, and lower amount of total sedentary behaviour had lower periodontal disease prevalence. Adjusted multivariable regression models showed that higher sedentary behaviour (more than 7.5 h/day) was associated with higher odds of periodontal disease (OR = 1.17; 95% confidence interval = 1.00-1.36; p = .045).

CONCLUSIONS

The findings showed that higher sedentary behaviour is associated with higher odds of periodontal disease. Future prospective longitudinal studies and strategies are needed to investigate implications further and define the magnitude of the association between physical activity and periodontal disease.

The impact of nutrition and lifestyle modification on health

The main recommendations from public health entities include healthy diets and physical activity as the main lifestyle factors impacting the development of chronic diseases such as cardiovascular and metabolic diseases, cancer, and even neurological diseases. Randomized clinical trials have been designed to demonstrate those lifestyle modifications can change the pattern of chronic diseases development and progression. Among these, nutrition is one of the most impacting factors. Therefore, nutrition and diets were also included in different randomized clinical trials, and most of them showed a favorable impact of nutrition modification on the participant's health. Nevertheless, study designs were considerably different, and future studies are needed to support nutrition modifications further. The choice of a healthy considered diet, like the Mediterranean diet, was shown to impact chronic diseases, cardiovascular risk, and adult life expectancy mainly due to its anti-inflammatory and antioxidant properties. Furthermore, a high intake of fibers, fruits, and vegetables together with a low intake of fat and energy-dense, processed foods contribute to an inflammation reduction and a more robust immune system leading. Besides these well-known properties, all lifestyle modifications must be personalized according to the availability of foods, geographic localizations, and the healthy status of the patient.

Personalized Lifestyle Intervention and Functional Evaluation Health Outcomes SurvEy: Presentation of the LIFEHOUSE Study Using N-of-One Tent-Umbrella-Bucket Design

The working definition of health is often the simple absence of diagnosed disease. This common standard is limiting given that changes in functional health status represent early warning signs of impending health declines. Longitudinal assessment of functional health status may foster prevention of disease occurrence and modify disease progression. The LIFEHOUSE (Lifestyle Intervention and Functional Evaluation-Health Outcomes SurvEy) longitudinal research project explores the impact of personalized lifestyle medicine approaches on functional health determinants. Utilizing an adaptive tent-umbrella-bucket design, the LIFEHOUSE study follows the functional health outcomes of adult participants recruited from a self-insured employee population. Participants were each allocated to the tent of an all-inclusive N-of-one case series. After assessing medical history, nutritional physical exam, baseline functional status (utilizing validated tools to measure metabolic, physical, cognitive, emotional and behavioral functional capacity), serum biomarkers, and genomic and microbiome markers, participants were assigned to applicable umbrellas and buckets. Personalized health programs were developed and implemented using systems biology formalism and functional medicine clinical approaches. The comprehensive database (currently 369 analyzable participants) will yield novel interdisciplinary big-health data and facilitate topological analyses focusing on the interactome among each participant's genomics, microbiome, diet, lifestyle and environment.

Revisiting food-sourced vitamins for consumer diet and health needs: a perspective review, from vitamin classification, metabolic functions, absorption, utilization, to balancing nutritional requirements

The significant attention gained by food-sourced vitamins has provided insights into numerous current researches; for instance, the potential reversal of epigenetic age using a diet and lifestyle intervention, the balance between food and dietary supplements in the general population, the role of diet and food intake in age-related macular degeneration, and the association of dietary supplement use, nutrient intake and mortality among adults. As relevant literature about food-sourced vitamin increases, continuous synthesis is warranted. To supplement existing information, this perspective review discussed food-sourced vitamins for consumer diet and health needs, scoping from vitamin absorption, metabolic functions, utilization, to balancing nutritional requirements. Relevant literatures were identified through a search of databases like Google Scholar, Web of Science, the Interscience Online Library, ScienceDirect, and PubMed. We demonstrated that vitamins whether from plant- and animal-based sources are prerequisites for the metabolic functions of the human body. The fat- and water-soluble classification of vitamins remains consistent with their respective absorption and dissolution potentials, underpinned by numerous physiological functions. Vitamins, largely absorbed in the small intestine, have their bioavailability dependent on the food composition, its associated interactions, as well as alignment with their metabolic functions, which involves antioxidants, coenzymes, electron acceptor/donor, and hormones. Moreover, vitamin deficiencies, in every form, pose a serious threat to human health. Vitamin toxicities remain rare, but can still occur mainly from supplementation, although it appears much less in water-soluble vitamins of which some excesses get readily removed by the human body, different from the fat-soluble ones that are stored in tissues and organs. Besides discussions of absorption, transport, and cellular uptake of vitamins, this perspective review also included approaches to meeting vitamin requirements and therapeutic strategies against micronutrient deficiency and COVID-19. We have also attempted on how to strike the balance between food-sourced vitamins and dietary supplements.

Consumers' Preferences and Willingness to Pay for Personalised Nutrition

INTRODUCTION

Personalised nutrition (PN) has great potential for disease prevention, particularly if coupled with the power and accessibility of mobile technology. However, success of PN interventions will depend on the willingness of users to subscribe. This study investigates the factors associated with potential users' perceived value of PN and heterogeneity in these values.

METHODS

A discrete choice experiment was carried out in a representative sample (N = 429 valid responses) from the adult population in Spain. The results were analysed in line with McFadden's Random Utility Theory, using conditional and mixed logit models in addition to a latent class logit model.

RESULTS

The conditional and mixed logit models revealed the existence of a significant preference and willingness to pay for personalised nutrition, but the effect on average was not large for the highest level of personalisation. The latent class logit revealed four classes of respondent: those who would be likely to pay for a high level of personalised nutrition service, those who would use it if it were heavily subsidised, those who would use only a basic nutrition service, and those who would not be willing to engage. These results could be useful for the design and targeting of effective personalised nutrition services.

CONCLUSIONS

Over half of adults currently perceive some individual benefit in a high level of PN, which may justify some degree of public subsidy in investment and delivery of such a service.

A Discovery that Reframes the Whole of Global Healthcare in the 21st Century: The Importance of the Imprintome

Within the genome exists a specific subset of genes whose expression is controlled by epigenetic marks. These tags can be modified by lifestyle factors including diet, behavior, environment and social interactions. Differences in genetic expression, despite identical genes, is explained in part through metastable epialleles-alleles that, while genetically indistinguishable, are variably expressed as a function of epigenetic modification. As a group, these metastable epialleles have been given a unique descriptive name: the imprintome. This breakthrough in understanding genetic expression has led to a wider recognition that our genes are fundamentally controlled at two levels. One is the hardware of the genetic code, which is modified slowly by natural selection through mutational changes in the genome over centuries of time. The other is the software that controls the expression of our genetic code, converting nucleotide sequences into phenotype in response to the imprinting of our epigenome. Acting as a rapid translator for real time changes, the imprintome responds to environmental and lifestyle inputs by genomic methylation and histone modifications that affect promoter accessibility and transcription factor activity. In application, this understanding of the plasticity of the imprintome necessitates a rethinking of both health and disease states. It's a concept that cuts across all forms of healthcare: physical, metabolic, and cognitive-behavioral interventions. But at the same time, it is an aggregating concept-one that brings disciplines together to collaborate on the personalization of health and the delivery of truly individualized care. This article reviews the development of the concept of the imprintome, as well as clinical studies supporting its importance as a potential driver of change in global health care.

Associations of environment and lifestyle factors with suboptimal health status: a population-based cross-sectional study in urban China

INTRODUCTION

Suboptimal health status (SHS), an intermediate state between chronic disease and health, is characterized by chronic fatigue, non-specific pain, headaches, dizziness, anxiety, depression, and functional system disorders with a high prevalence worldwide. Although some lifestyle factors (e.g. smoking, alcohol consumption, physical exercise) and environmental factors (e.g. air quality, noise, living conditions) have already been studied, few studies can comprehensively illustrate the associations of lifestyle and environment factors with general, physical, mental, and social SHS.

METHODS

A cross-sectional study was conducted among 6750 urban residents aged 14 years or over in five random cities from September 2017 to September 2018 through face-to-face questionnaires. There were 5881 valid questionnaires with a response rate of 87%. A general linear model and structural equation model were developed to quantify the effects of lifestyle behaviors and environment factors on SHS.

RESULTS

The detection rates of general, physical, mental, and social SHS were 66.7, 67.0, 65.5, and 70.0%, respectively. Good lifestyle behaviors and favorable environment factors positively affected SHS (P < 0.001). Lifestyle behaviors had the largest effect on physical SHS (β = - 0.418), but the least on social SHS (β = - 0.274). Environment factors had the largest effect on mental SHS (β = 0.286), but the least on physical SHS (β = 0.225).

CONCLUSIONS

Lifestyle behaviors and environment factors were important influencing factors of SHS. Physical SHS was more associated with lifestyle. Lifestyle and environment were similarly associated with mental and social SHS.

The Role of Stress Perception and Coping with Stress and the Quality of Life Among Multiple Sclerosis Patients

Purpose

Multiple sclerosis (MS) is one of the most common neurological disorders and a cause of disability in young adults. Adequate stress management in MS patients may merit the benefits of both physical and psychological well-being. This study aimed to evaluate the quality of life in MS patients and its correlation with stress levels and coping strategies.

Methods

This descriptive and correlational study was conducted among 109 patients diagnosed with relapsing-remitting MS (RRMS). The study was based on a questionnaire designed by the authors and the following standardized questionnaires: the Perceived Stress Scale (PSS-10), the Inventory for Measuring Coping with Stress (Mini-COPE), and the Multiple Sclerosis International Quality of Life Questionnaire (MusiQoL).

Results

Data analysis showed that 47.71% of the patients experienced a high level of stress, and the most often used strategies under challenging situations included seeking emotional support (2.11) and active coping (1.96). Also, it showed that when the level of stress is higher, the QOL in all domains is lower. Coping strategies such as sense of humor, turning to religion, self-distraction, denial, venting, substance use, behavioral disengagement, and self-blame are negatively correlated with the quality of life of MS.

Conclusion

Quality of life in MS patients is negatively affected by a higher level of perceived stress. The use of coping strategies such as active coping, positive reframing, acceptance, and seeking emotional and instrumental support is positively correlated with the quality of life of MS patients.

Primary Disease Prevention for Southwest American Indian Families During the COVID-19 Pandemic: Camp in a Box

The goal of the American Indian Youth Wellness Camp in a Box was to engage, educate and empower families to improve their health and overall well-being during the COVID-19 pandemic. Camp in a Box was a 9-week program, inclusive of a 1-week intensive camp component followed by an 8-week booster component with content focused on nutrition, mental health and physical activity education. The Camp in a Box is a Tribal/Urban Indian-University partnership, and materials were developed to replace an existing weeklong residential camp and to comply with social distancing guidelines. Fourteen American Indian families from Tribal/Urban Indian communities in the southwestern United States participated (36 children aged 2-18 years; 32 adults). The intensive camp week included daily materials for families to complete together, Monday through Friday. Materials were provided for approximately 4 h of activities per day. The booster sessions began after camp week and included approximately 4 h of supplementary activities designed to be completed at any time most convenient for the family over the course of the week. Activities were designed to encourage interaction among family members with materials and supplies for parents and youth to participate. Self-reported outcomes suggested that families changed their eating habits to include more vegetables, less sweets and junk food. Parents reported an increase in family physical activity and that the activities brought the family closer together. Our Camp in a Box program was feasible and well-received until school began. During camp week, 100% of recruited families participated; at Booster Week 8, ten families (71%) remained enrolled and active. Camp in a Box is a feasible alternative to residential camps for promotion of health behaviors associated with metabolic disease prevention among American Indian families. In contrast to residential camps for youth, Camp in a Box offers an opportunity to engage the entire family in health promotion activities.

An evolutionary mismatch narrative to improve lifestyle medicine: a patient education hypothesis

An evolutionary perspective provides a unifying explanation for the modifiable risk factors and lifestyle-based interventions for the leading causes of morbidity and mortality globally. Non-communicable diseases develop from an evolutionary mismatch between the prior environment and modern patterns of behavior; however, it is unclear whether an evolutionary mismatch narrative could promote positive behavior change in patients. We hypothesize that educating patients about evolutionary mismatch could augment efforts to improve healthful behavior. Specifically, explaining the 'why' behind what is being recommended could promote health literacy and adherence. Furthermore, we offer suggestions of how clinicians could educate patients about evolutionary mismatch for key-lifestyle factors, diet and physical activity, as well as several specific modern diseases. We also consider how to sidestep patients' skepticism of evolutionary theory. Here, we lay the groundwork for research on how educating patients with an evolutionary mismatch narrative could impact health behaviors and improve outcomes.

A Pantheoretical Framework to Optimize Adherence to Healthy Lifestyle Behaviors and Medication Adherence: The Use of Personalized Approaches to Overcome Barriers and Optimize Facilitators to Achieve Adherence

Patient nonadherence to healthy lifestyle behaviors and medical treatments (like medication adherence) accounts for a significant portion of chronic disease burden. Despite the plethora of behavioral interventions to overcome key modifiable/nonmodifiable barriers and enable facilitators to adherence, short- and long-term adherence to healthy lifestyle behaviors and medical treatments is still poor. To optimize adherence, we aimed to provide a novel mobile health solution steeped in precision and personalized population health and a pantheoretical approach that increases the likelihood of adherence. We have described the stages of a pantheoretical approach utilizing tailoring, clustering/profiling, personalizing, and optimizing interventions/strategies to obtain adherence and highlight the minimal engineering needed to build such a solution.

Effectiveness of Workplace Yoga Interventions to Reduce Perceived Stress in Employees: A Systematic Review and Meta-Analysis

Work-related stress represents a relevant public health issue and solution strategies are mandatory. Yoga is a common approach to manage stress and its effectiveness has been extensively confirmed. Therefore, this study aims systematically to review the effectiveness of Yoga interventions carried out at workplace on work-related stress among employees and to assess their impact quantitatively. Springerlink, MEDLINE, PubMed, CINAHL, Web of Science, Scopus, Cochrane CENTRAL and PEDro databases were searched. Clinical trials comparing workplace Yoga interventions to control groups, and evaluating perceived stress as outcome measure, were assessed for eligibility. All forms and styles of Yoga were considered for the analysis. Out of 3392 initially identified, 6 studies were included in the meta-analysis; 266 participants practicing Yoga interventions at worksite were compared to 221 subjects in control group. Included studies showed "some concerns" about different domains of source of bias. Quantitative analysis showed an overall effect size of -0.67 [95% confidence interval (CI): -0.86, -0.49] in favor of Yoga intervention in reducing stress outcome measures. Hence, workplace Yoga interventions were more effective when compared to no treatment in work-related stress management. Further high-quality studies are needed to improve the validity of these results and to specify more characteristics of the Yoga intervention, such as style, volume, and frequency.

A Personalized eHealth Intervention for Lifestyle Changes in Patients With Cardiovascular Disease: Randomized Controlled Trial

Background

Behavior change methods involving new ambulatory technologies may improve lifestyle and cardiovascular disease outcomes.

Objective

This study aimed to provide proof-of-concept analyses of an intervention aiming to increase (1) behavioral flexibility, (2) lifestyle change, and (3) quality of life. The feasibility and patient acceptance of the intervention were also evaluated.

Methods

Patients with cardiovascular disease (N=149; mean age 63.57, SD 8.30 years; 50/149, 33.5% women) were recruited in the Do Cardiac Health Advanced New Generation Ecosystem (Do CHANGE) trial and randomized to the Do CHANGE intervention or care as usual (CAU). The intervention involved a 3-month behavioral program in combination with ecological momentary assessment and intervention technologies.

Results

The intervention was perceived to be feasible and useful. A significant increase in lifestyle scores over time was found for both groups (F_2,146.6=9.99; P<.001), which was similar for CAU and the intervention group (F_1,149.9=0.09; P=.77). Quality of life improved more in the intervention group (mean 1.11, SD 0.11) than CAU (mean −1.47, SD 0.11) immediately following the intervention (3 months), but this benefit was not sustained at the 6-month follow-up (interaction: P=.02). No significant treatment effects were observed for behavioral flexibility (F_1,149.0=0.48; P=.07).

Conclusions

The Do CHANGE 1 intervention was perceived as useful and easy to use. However, no long-term treatment effects were found on the outcome measures. More research is warranted to examine which components of behavioral interventions are effective in producing long-term behavior change.

Reflections on the COVID-19 Pandemic

There is an emerging understanding that the severity of viral infections is not only related to the nature of the viral vector, but also to various social and biological factors, a number of which can be modified. The recent COVID-19 pandemic raises the issue as to what approaches might be important in reducing the severity of future viral pandemics beyond that of the pursuit of specific immunization to the vector and the development of drugs to treat its unique mechanism of replication. There is now evidence that lifestyle and environmental factors can serve as immunoadjuvants. Personalized lifestyle and environmental factors may therefore play a significant role in determining both the infectivity and pathogenicity of viruses. Once identified, these factors lend themselves to specific personalized intervention. This intervention focuses on renewal of immune system function through diet, activity, fluid intake, sleep, intestinal microbiome composition, and stress management. As more is learned about the factors that influence the function of specific components of the immune system, it becomes more evident that these modifiable factors have significant impact on the individual response to a viral exposure.

Precision Medicine in Lifestyle Medicine: The Way of the Future?

Precision medicine has captured the imagination of the medical community with visions of therapies precisely targeted to the specific individual's genetic, biological, social, and environmental profile. However, in practice it has become synonymous with genomic medicine. As such its successes have been limited, with poor predictive or clinical value for the majority of people. It adds little to lifestyle medicine, other than in establishing why a healthy lifestyle is effective in combatting chronic disease. The challenge of lifestyle medicine remains getting people to actually adopt, sustain, and naturalize a healthy lifestyle, and this will require an approach that treats the patient as a person with individual needs and providing them with suitable types of support. The future of lifestyle medicine is holistic and person-centered rather than technological.

What is the Best Way to Assess Functional Health?: The History of the Development and Application of the Patient Reported Outcome Measurement Information System (PROMIS)

For more than seven decades, the World Health Organization has defined health as a "state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." Among researchers and clinicians, translation of this definition into outcomes measurements has proven challenging. The Patient-Reported Outcomes Measurement Information System (PROMIS) is an initiative connected to the National Institutes of Health Roadmap for Medical Research. Recently, this tool was successfully applied in a comparative evaluation of intervention models (the Functional Medicine model versus the standard-of-care model for primary medicine) in patients with chronic health complaints. This study demonstrated that information derived from validated patient-reported outcomes surveys can be used to design clinical research approaches focused on improving health and well-being.

Systems Biology Meets Functional Medicine

Through experiences gained over the past 3 decades, the development and application of the Functional Medicine model has demonstrated its ability to improve clinical decision making in the treatment of patients with complex chronic disease. The Functional Medicine model provides a system that effectively translates the emerging understanding of the gene-environment regulation of the structure and function of the individual into clinical practice.

Emergence of digital biomarkers to predict and modify treatment efficacy: machine learning study

OBJECTIVES

Development of digital biomarkers to predict treatment response to a digital behavioural intervention.

DESIGN

Machine learning using random forest classifiers on data generated through the use of a digital therapeutic which delivers behavioural therapy to treat cardiometabolic disease. Data from 13 explanatory variables (biometric and engagement in nature) generated in the first 28 days of a 12-week intervention were used to train models. Two levels of response to treatment were predicted: (1) systolic change ≥10 mm Hg (SC model), and (2) shift down to a blood pressure category of elevated or better (ER model). Models were validated using leave-one-out cross validation and evaluated using area under the curve receiver operating characteristics (AUROC) and specificity- sensitivity. Ability to predict treatment response with a subset of nine variables, including app use and baseline blood pressure, was also tested (models SC-APP and ER-APP).

SETTING

Data generated through ad libitum use of a digital therapeutic in the USA.

PARTICIPANTS

Deidentified data from 135 adults with a starting blood pressure ≥130/80, who tracked blood pressure for at least 7 weeks using the digital therapeutic.

RESULTS

The SC model had an AUROC of 0.82 and a sensitivity of 58% at a specificity of 90%. The ER model had an AUROC of 0.69 and a sensitivity of 32% at a specificity at 91%. Dropping explanatory variables related to blood pressure resulted in an AUROC of 0.72 with a sensitivity of 42% at a specificity of 90% for the SC-APP model and an AUROC of 0.53 for the ER-APP model.

CONCLUSIONS

Machine learning was used to transform data from a digital therapeutic into digital biomarkers that predicted treatment response in individual participants. Digital biomarkers have potential to improve treatment outcomes in a digital behavioural intervention.

Personalized intervention to improve stress and sleep patterns for glycemic control and weight management in obese Emirati patients with type 2 diabetes: a randomized controlled clinical trial

Background: There is growing evidence that stress and sleep deprivation are involved in development of type 2 diabetes (T2DM). The latter is one of the most challenging health problems in the UAE. Therefore, the present study aimed to investigate the effects of personalized intervention on glycemic and weight control in Emirati patients with T2DM. The intervention involved assessment and modification of stress levels and sleep patterns. Methods: This was a randomized controlled study conducted on 51 Emirati patients with T2DM (age 18-60 years, body-mass index (BMI) ≥25 kg/m²): those in the intervention group who completed the trial numbered 18 and those in the control group who completed the trial numbered 17. Heart-rate variability was used for real-life and long-term assessments of stress, sleep, and recovery. Body weight, BMI, HbA_1c and lipid profile were included in the investigation. The National Clinical Trial identifier number is NCT03644134. Results: Percentage change in body weight was significantly greater (P<0.05) in the intervention group (-3.2±2.9) than the control group (-0.02). Percentage change in the BMI of the intervention group was -4.50±5.9, while the control group exhibited less change in BMI (-0.0003±3.3, P<0.05). In addition, a significant reduction in HbA_1c was observed in the intervention group (-5.3±15.7) and an increase of 9.9±13.1 was observed in the control group (P<0.01). Conclusion: The findings of the present study show that personalized approaches that reduce stress levels, increase recovery levels, and promote healthy sleep habits play an important role in weight management and glycemic control in T2DM.

Longitudinal analysis of biomarker data from a personalized nutrition platform in healthy subjects

The trend toward personalized approaches to health and medicine has resulted in a need to collect high-dimensional datasets on individuals from a wide variety of populations, in order to generate customized intervention strategies. However, it is not always clear whether insights derived from studies in patient populations or in controlled trial settings are transferable to individuals in the general population. To address this issue, a longitudinal analysis was conducted on blood biomarker data from 1032 generally healthy individuals who used an automated, web-based personalized nutrition and lifestyle platform. The study had two main aims: to analyze correlations between biomarkers for biological insights, and to characterize the effectiveness of the platform in improving biomarker levels. First, a biomarker correlation network was constructed to generate biological hypotheses that are relevant to researchers and, potentially, to users of personalized wellness tools. The correlation network revealed expected patterns, such as the established relationships between blood lipid levels, as well as novel insights, such as a connection between neutrophil and triglyceride concentrations that has been suggested as a relevant indicator of cardiovascular risk. Next, biomarker changes during platform use were assessed, showing a trend toward normalcy for most biomarkers in those participants whose values were out of the clinically normal range at baseline. Finally, associations were found between the selection of specific interventions and corresponding biomarker changes, suggesting directions for future study.

Making Genetic Testing More Clinically Valuable

The concepts discussed in this article-from the limitations of current assessment tools, to the emerging research on polygenic analyses, to my own thoughts about defining functional genetic categories-are all very relevant to the goal of improving the precision implementation of personalized lifestyle medicine for many complex chronic diseases. By using this lens of understanding the interaction between genes and lifestyle, many clinical studies demonstrating the effectiveness of lifestyle in improving health outcome in patients with chronic diseases can be identified.

Red Meat Consumption (Heme Iron Intake) and Risk for Diabetes and Comorbidities?

PURPOSE OF REVIEW

To examine the role of red meat consumption, especially heme iron intake, and risk for diabetes and its comorbidities.

RECENT FINDINGS

Studies consistently show that consumption of red meat has been contributory to a multitude of chronic conditions such as diabetes, CVD, and malignancies. There are various emerging reasons that strengthen this link-from the basic constituents of red meat like the heme iron component, the metabolic reactions that take place after consumption, and finally to the methods used to cook it. The causative links show that even occasional use raises the risk of T2DM. Prior studies show how nitrites and nitrates in red meat can lead to increased insulin resistance, dysregulated blood glucose levels, and elevated oxidative stress all leading to chronic diseases. With the rise in these preventable chronic diseases, we examine how disease-causing links can be eliminated with appropriate lifestyle choices.

Lifestyle Medicine: A Brief Review of Its Dramatic Impact on Health and Survival

By ignoring the root causes of disease and neglecting to prioritize lifestyle measures for prevention, the medical community is placing people at harm. Advanced nations, influenced by a Western lifestyle, are in the midst of a health crisis, resulting largely from poor lifestyle choices. Epidemiologic, ecologic, and interventional studies have repeatedly indicated that most chronic illnesses, including cardiovascular disease, cancer, and type 2 diabetes, are the result of lifestyles fueled by poor nutrition and physical inactivity.In this article, we describe the practice of lifestyle medicine and its powerful effect on these modern instigators of premature disability and death. We address the economic benefits of prevention-based lifestyle medicine and its effect on our health care system: A system on the verge of bankruptcy. We recommend vital changes to a disastrous course. Many deaths and many causes of pain, suffering, and disability could be circumvented if the medical community could effectively implement and share the power of healthy lifestyle choices. We believe that lifestyle medicine should become the primary approach to the management of chronic conditions and, more importantly, their prevention. For future generations, for our own health, and for the Hippocratic Oath we swore to uphold ("First do no harm"), the medical community must take action. It is our hope that the information presented will inspire our colleagues to pursue lifestyle medicine research and incorporate such practices into their daily care of patients. The time to make this change is now.

Effect of Diet Change on Gut Microbiota: Observational Pilot Study of Four Urban Couples

Background

Recent studies have focused on changes in gut microbiota following a dietary change. We identified how the distribution of gut microbiota changed when the dietary habits of young city dwellers improved using an intervention in which married couples shared the same dietary habits.

Methods

Four married couples in their 30s with irregular eating habits and sedentary lifestyles were asked whether they had any uncomfortable symptoms. A nutritionist advised them to reduce their intake of processed meats, carbonated beverages, and late-night snacks. After a 6-week intervention, subjects were asked whether they observed any changes in their symptoms. Their stool samples were collected before and after the intervention and analyzed to determine whether the gut microbiota had changed.

Results

After the dietary intervention, some subjective symptoms of the participants improved. Specifically, a subject who complained of frequent abdominal pain/diarrhea and one who complained of fatigue showed improvement in those symptoms. In addition, some subjects showed improvements in symptoms such as skin disease or constipation. Intestinal microorganisms between spouses who share the same dietary habits were found to be similar.

Conclusion

Improvements in eating habits can change the distribution of gut microbiota and alleviate various uncomfortable medical symptoms. Within married couples, the distribution of gut microbiota became similar when the spouses shared the same dietary habits. These results suggest a possible correlation between family-level changes in eating habits and the health of all family members.

Cardiology Meets Personalized Lifestyle Medicine

This is a very exciting time for medicine. We are witnessing the creation of a new approach to the prevention and treatment of cardiovascular disease. It is an omnigenic approach-powered by systems biology-to assembling patient-specific information about how genes and lifestyle interact. When combined with other new technologies such as artificial intelligence and machine learning informatics, the result will be the development of a precision form of personalized lifestyle medicine applied to cardiovascular disease. This advancement will be a gateway for change throughout the entire segment of the health care system that is focused on the many complex chronic conditions affecting our world population.

Implications of dietary ω-3 and ω-6 polyunsaturated fatty acids in breast cancer

Breast cancer represents one of the most common forms of cancer in women worldwide, with an increase in the number of newly diagnosed patients in the last decade. The role of fatty acids, particularly of a diet rich in ω-3 and ω-6 polyunsaturated fatty acids (PUFAs), in breast cancer development is not fully understood and remains controversial due to their complex mechanism of action. However, a large number of animal models and cell culture studies have demonstrated that high levels of ω-3 PUFAs have an inhibitory role in the development and progression of breast cancer, compared to ω-6 PUFAs. The present review focused on recent studies regarding the correlation between dietary PUFAs and breast cancer development, and aimed to emphasize the main molecular mechanisms involved in the modification of cell membrane structure and function, modulation of signal transduction pathways, gene expression regulation, and antiangiogenic and antimetastatic effects. Furthermore, the anticancer role of ω-3 PUFAs through the modulation of microRNA expression levels was also reviewed.

A Systems Medicine Approach: Translating Emerging Science into Individualized Wellness

In today's aging society, more people are living with lifestyle-related noncommunicable diseases (NCDs) such as cardiovascular disease, type 2 diabetes, obesity, and cancer. Numerous opinion-leader organizations recommend lifestyle medicine as the first-line approach in NCD prevention and treatment. However, there is a strong need for a personalized approach as "one-size-fits-all" public health recommendations have been insufficient in addressing the interindividual differences in the diverse populations. Advancement in systems biology and the "omics" technologies has allowed comprehensive analysis of how complex biological systems are impacted upon external perturbations (e.g., nutrition and exercise), and therefore is gradually pushing personalized lifestyle medicine toward reality. Clinicians and healthcare practitioners have a unique opportunity in advocating lifestyle medicine because patients see them as a reliable source of advice. However, there are still numerous technical and logistic challenges to overcome before personal "big data" can be translated into actionable and clinically relevant solutions. Clinicians are also facing various issues prior to bringing personalized lifestyle medicine to their practice. Nevertheless, emerging ground-breaking research projects have given us a glimpse of how systems thinking and computational methods may lead to personalized health advice. It is important that all stakeholders work together to create the needed paradigm shift in healthcare before the rising epidemic of NCDs overwhelm the society, the economy, and the dated health system.

Management of Chronic Daily Headache and Psychiatric Co-Morbidities by Lifestyle Modification: Participatory Action Research Combining New Communication Media

Background

Lifestyle modification has a significant role in chronic daily headache (CDH) management. Participatory action research (PAR) can play an important role in managing chronic medical conditions. However, it has been scarcely used in CDH management.

Objectives

This study aimed to empower patients with CDH to modify their lifestyle in order to reduce both their headache and related psychiatric co-morbidities in a multidisciplinary headache clinic at Baqiyatallah hospital, Tehran, IR Iran.

Methods

In the PAR plan, 37 patients (27 females) diagnosed with CDH were selected using purposeful sampling. Along with face-to-face group sessions, all available communication means such as phone calls, emails, short message system (SMS), and social media (Telegram) were used to facilitate the process. Questionnaires of health promotion lifestyle profile (HPLPІІ), visual analog scale (VAS), and depression-anxiety-stress scale (DASS21) were used to collect data. The data were analyzed using SPSS software.

Results

Mean age of the patients was 38.33 (± 9.7) years. Both “general pain” and “the worst imaginable pain” reduced (mean of reduction: 2.56 ± 2.7 and 2.3 ± 2.9, respectively, P < 0.001). > 50% of pain reduction occurred in “the worst imaginable pain" category (-1.45 ± 2.02, P < 0.001) and mean VAS score reduced to 5.20 (± 2.3) compared to the start of the study (7.50 ± 1.9, P < 0.001). Mean DASS-21 score also reduced significantly for depression (P < 0.016), anxiety (P < 0.026), and stress (P < 0.008). HPLPІІ score significantly improved (118.17 ± 14.8 vs. 160.83 ± 16.4, P < 0.001) and the highest increase was seen in the subscale of "stress management" (17.73 ± 2.8 vs. 25.53 ± 3.9, P < 0.001).

Conclusions

The empowering PAR plan combined with new communication tools helped the CDH patients better handle their lifestyle, reduce their headache, and lower their symptoms. Further studies with better use of currently available communication tools and social media are recommended for action research to be more applicable.

Genomic medicine in gastroenterology: A new approach or a new specialty?

Throughout history, many medical milestones have been achieved to prevent and treat human diseases. Man's early conception of illness was naturally holistic or integrative. However, scientific knowledge was atomized into quantitative and qualitative research. In the field of medicine, the main trade-off was the creation of many medical specialties that commonly treat patients in advanced stages of disease. However, now that we are immersed in the post-genomic era, how should we reevaluate medicine? Genomic medicine has evoked a medical paradigm shift based on the plausibility to predict the genetic susceptibility to disease. Additionally, the development of chronic diseases should be viewed as a continuum of interactions between the individual's genetic make-up and environmental factors such as diet, physical activity, and emotions. Thus, personalized medicine is aimed at preventing or reversing clinical symptoms, and providing a better quality of life by integrating the genetic, environmental and cultural factors of diseases. Whether using genomic medicine in the field of gastroenterology is a new approach or a new medical specialty remains an open question. To address this issue, it will require the mutual work of educational and governmental authorities with public health professionals, with the goal of translating genomic medicine into better health policies.

Personalized hypertension management in practice

The revolution occurring in genomic and personalized medicine is likely to have a significant impact on the management of hypertension. However, from the perspective of translating new knowledge into clinical practice, progress has been slow. This review article summarizes recent advances in hypertension-related diagnostics while also offering new perspective on hypertension management for the future. Such new perspectives will likely require a paradigm shift toward more integrated and holistic approaches for better prevention and treatment of hypertension in both individuals and the population as a whole.

The nutrition consult for recurrent stone formers

Diet is implicated in stone formation and growth. Whether alone or in concert with pharmacologics, dietary changes may be useful in reducing recurrence but only when they correct dietary stone-forming risks. Patients benefit from recommendations individualized to their food preferences as well as to lifestyle, age, food knowledge and access, preparation skills, and cultural and ethnic identities. Urologists can provide general dietary recommendations but often lack the time to provide the full complement of individualized nutrition care offered by a registered dietitian nutritionist (RDN). Urologists can partner with and refer patients to a RDN for any component of the nutrition care process: assessment of diet, diagnosis of dietary factors that contribute to stone risk factors, intervention formulation and implementation, and monitoring the effectiveness of the intervention and modifying it as needed to maintain suitably low dietary risk for stone recurrence.

An intervention study of individual, apoE genotype-based dietary and physical-activity advice: impact on health behavior

AIM

To assess the behavioral effects of receiving personal genetic information, using apoE genotypes as a tool for promoting lifestyle changes. apoE was chosen because it has a significant impact on lipid metabolism and cholesterol absorption, both factors in cardiovascular disease.

METHODS

This study was a 1-year intervention study of healthy adults aged 20-67 years (n = 107). Their behavioral changes were measured by diet (e.g., fat quality, as well as consumption of vegetables, berries, fruits, and fatty and sugary foods), alcohol consumption, and exercise. Health and taste attitudes were assessed with the Health and Taste Attitude Scales (HTAS). The measurements were performed 4 times: at baseline (T0), as well as 10 weeks (T1), 6 months (T2), and 12 months after baseline (T3). These behavioral effects were assessed for three groups: a high-risk (Ɛ4+; n = 16), a low-risk (Ɛ4-; n = 35), and a control group (n = 56).

RESULTS

Personal genetic information affected health behavior. Dietary fat quality improved more in the Ɛ4+ group than in the Ɛ4- and control groups after personal, genotype-based health advice. This change differed significantly between the Ɛ4+ and the control group (p < 0.05), but only for a short time.

CONCLUSION

Personal genetic information, based on apoE, may affect dietary fat quality. More research is required to determine how to utilize genotype-based health information and how to efficiently achieve long-term changes in the prevention of lifestyle-related diseases.

The alteration of NTproCNP plasma levels following anaerobic exercise in physically active young men

Objective:

Amino-terminal propeptide of C-type natriuretic peptide (NTproCNP) is a synthesis product of C-type natriuretic peptide (CNP). In this study, plasma levels of NTproCNP were compared before and after exercise in healthy young subjects who are physically active (PA) or not physically active (NPA).

Methods:

The study was carried on PA group (n=10) who defined the exercise duration more than 2.5 hours per week for at least one year and NPA group (n=10) whose exercise duration was lower than 1.5 hours per week. The level of maximal oxygen consumption was determined. Wingate exercise test was applied on the following day. Plasma NTproCNP levels were measured before the exercise and at the 1^st, 5^th and 30^th minute after the exercise.

Results:

Exercise duration of physically active group was reported as 11.3±5.0 hours per week. Basal NTproCNP levels of the groups were found to be comparable. NTproCNP levels in the 5^th minute (0.93±0.23 pmol/L; p<0.05) and in the 30^th minute (0.77±0.21 pmol/L p<0.05) after exercise were higher than the levels before exercise (0.64±0.29 pmol/L) in PA group. Additionally, the plasma levels of NTproCNP after 5^th minute of exercise were higher in PA group (0.93±0.23 pmol/L) than NPA group (0.74±0.16 pmol/L, p<0.05).

Conclusion:

Being physically active may be a fact affecting the secretion of CNP, which plays a protective role in endothelium, following exercise.

Beyond obesity and lifestyle: a review of 21st century chronic disease determinants

The obesity epidemic and associated chronic diseases are often attributed to modern lifestyles. The term "lifestyle" however, ignores broader social, economic, and environmental determinants while inadvertently "blaming the victim." Seen more eclectically, lifestyle encompasses distal, medial, and proximal determinants. Hence any analysis of causality should include all these levels. The term "anthropogens," or "…man-made environments, their by-products and/or lifestyles encouraged by these, some of which may be detrimental to human health" provides a monocausal focus for chronic diseases similar to that which the germ theory afforded infectious diseases. Anthropogens have in common an ability to induce a form of chronic, low-level systemic inflammation ("metaflammation"). A review of anthropogens, based on inducers with a metaflammatory association, is conducted here, together with the evidence for each in connection with a number of chronic diseases. This suggests a broader view of lifestyle and a focus on determinants, rather than obesity and lifestyle per se as the specific causes of modern chronic disease. Under such an analysis, obesity is seen more as "a canary in a mineshaft" signaling problems in the broader environment, suggesting that population obesity management should be focused more upstream if chronic diseases are to be better managed.
