The co-benefits of climate change mitigation strategies on cardiovascular health: a systematic review

Climate change is a significant threat to global human health and a leading cause of premature death. Global warming, leading to more extreme weather (in particular extreme heat events), and air pollution has been associated with increased cardiovascular disease (CVD) morbidity and mortality. According to the Global Burden of Disease Study 2019, 62% of the deaths attributable to climate change were from CVD. Climate change mitigation is a slow, steady process, and the concept of co-benefits has arisen to promote climate action. This systematic review examines how numerous mitigation strategies, such as plant-based diets, increasing green spaces, increasing active transport, using renewable energy sources, and smoking cessation, may have the co-benefit of reducing CVD. A mixed methods systematic review with narrative synthesis was conducted on four databases, according to the PRISMA guidelines. The articles retrieved (published between 2012 and 2022) had a mitigation strategy as the exposure, and CVD related morbidity or mortality reduction as an outcome. The review found that renewable energy has a stronger association with cardiovascular co-benefits compared to emission reduction targets. Multimodal transport is more beneficial for both the climate and cardiac health than zero emission vehicles. Diet modification, such as Mediterranean and plant-based-diets, is positively associated with CVD reduction. Proximity to green spaces and reducing urbanisation may also improve cardiac health. This systematic review demonstrates that implementing four mitigation strategies - increasing renewable energy use, active transport, green spaces, and plant-based diets; could lead to the co-benefit of reducing CVD morbidity and mortality. Furthermore, it illustrates the importance of plant-based diets and active transport to improve cardiovascular health. This research received no specific grant from any funding agency in the public, commercial or not-for-profit sectors.

Air pollution generated in an industrial region: Effect on the cardiovascular health of humans and damage caused to a plant species, Piper gaudichaudianum (Piperaceae), used for biomonitoring

Atmospheric pollution due to anthropogenic activities is a complex mixture of gasses and particulate matter (PM) that is currently one of the main causes of premature death in the world. Similarly, it is also capable of directly interfering with plant species by reducing their photosynthetic capacity and growth and killing cells. This work is about an observational study conducted in a region with two industries: a mine and an automobile parts manufacturer. Mining rocks is a source of PM in the air like that caused by other industrial activities. Twenty-five people that work or live in the industrial region cited (area A) and 25 people that live further away (area B) were selected to evaluate their vital signs and conduct a transthoracic echocardiogram. Leaves of Piper gaudichaudianum (Piperaceae), a native plant species, were also collected in both areas and evaluated in a laboratory. The PM accumulated on the leaves was evaluated using scanning electron microscopy (SEM) and inductively coupled plasma-optical emission spectrometry (ICP-OES). A statistical difference (P < 0.05) was verified for the levels of systolic blood pressure (SBP), diastolic blood pressure (DBP), and left ventricular mass index by echocardiography; the values were greater in people in area A. For the plant analysis, there was a statistical difference for all characters evaluated, chlorophyll levels, fresh mass, dry mass and leaf area were reduced, and thickness was greater in area A (P < 0.001). The PM analysis revealed a predominance of silicon, iron, and aluminum chemical elements. The present study suggests that particulate matter pollution is harmful to both humans and the flora.

Sex differences in acute myocardial infarction - Preliminary results from an umbrella review

Abstract Background Cardiovascular disease (CVD) is the leading cause of premature death among women, and the negative impact on public health is profound. Women have higher rates of comorbidities, complications such as stroke, in addition to higher mortality compared to men (1-6) and targeting sex-related differences regarding the treatment of CVD in women is of great importance to prevent the number of CVD events. The purpose of this study was to get an overview of the systematic reviews and meta-analyses investigating sex differences in patients with acute myocardial infarction (AMI) the past 10 years. Methods A systematic search was carried out in Epistemonikos, the largest database of systematic reviews that screens PubMed, Cochrane, Embase, CINAHL, PsycInfo and others (i.e., currently nine databases) (7, 8). The search was conducted 12 January 2024, with the general search strings: (1) sex differences OR gender differences AND myocardial infarction, (2) sex differences OR gender differences OR women OR female AND myocardial infarction. The search was restricted to systematic reviews conducted the last 10 years. Results Forty-nine (search 1: 19, search 2: 30) systematic reviews and meta-analyses were identified, and five studies investigating sex differences in relation to AMI were included. Two systematic reviews, Babioakis (2021) and Meer (2015), reported of longer door-to-balloon (D2B) time and/or symptom-to-balloon (S2B) time in female patients presenting with STEMI and referred for PCI, compared to male patients (9). Chaudhary (2022) investigated adverse event of MINOCA (more commonly in women/ younger age (51-59 years) and reported higher risk of MACE among women than men (10.1% vs. 9.1%, OR 1.15, 1.04-1.23), in addition to higher incidence of stroke (3.5% vs. 2.2%, OR 1.3, 1.01-1.68), however no significantly differences were observed for all-cause mortality, non-fatal AMI, and cardiovascular readmissions between the groups (10). Three systematic reviews reported of higher risk of mortality after STEMI among women, compared to men (11-13). Xi (2022) reported of higher risk of short-term mortality (RR, 1.73; 95% CI 1.53 to 1.96)) (adjusted RR, 1.24; 95% CI 1.11 to 1.38) (13), Pancholy (2014) reported of higher risk of in-hospital mortality (RR, 1.93; 95% CI, 1.75-2.14) (adjusted RR, 1.48; 95% CI, 1.07-2.05) (11), and van der Meer (2015) reported of higher crude short- and long-term mortality in women, in addition to less use of GP IIb/IIIa inhibitors in women, compared to men (women 51%, men 57%) (12). Conclusions Our umbrella review revealed that women had longer timeline for treatment in AMI, had less use of medication and higher risk of mortality and MACE compared to men. Clinical practice needs further improvements in management in female patients.

PENINGKATAN PEMAHAMAN BAHAYA ROKOK PADA REMAJA DALAM PENGENDALIAN HIPERTENSI

Hypertension is one of the causes of premature death in people around the world. One of the risk factors for hypertension is smoking habits. The long-term effects of smoking are increased blood pressure due to increased inflammatory substances, endothelial dysfunction, plaque formation, and vascular damage. Therefore, this community service aims to increase teenagers' understanding of the dangers of smoking so that they can hopefully be able to control the incidence of hypertension sufferers. This activity was attended by 30 teenagers in Setiling 3 Hamlet, Setiling Village, North Batukliang District, Central Lombok, West Nusa Tenggara using LCD projectors and leaflets as media. The method used is lecture and discussion. This service is able to increase the knowledge and understanding of teenagers regarding the dangers of smoking on health, especially in increasing the risk of hypertension.

The role of positive emotion in harmful health behavior: Implications for theory and public health campaigns

Meta-analyses have concluded that positive emotions do not reduce appetitive risk behaviors (risky behaviors that fulfill appetitive or craving states, such as smoking and excessive alcohol use). We propose that this conclusion is premature. Drawing on the Appraisal Tendency Framework and related theories of emotion and decision-making, we hypothesized that gratitude (a positive emotion) can decrease cigarette smoking, a leading cause of premature death globally. A series of multimethod studies provided evidence supporting our hypothesis (collective N = 34,222). Using nationally representative US samples and an international sample drawn from 87 countries, Studies 1 and 2 revealed that gratitude was inversely associated with likelihood of smoking, even after accounting for numerous covariates. Other positive emotions (e.g., compassion) lacked such consistent associations, as expected. Study 3, and its replication, provided further support for emotion specificity: Experimental induction of gratitude, unlike compassion or sadness, reduced cigarette craving compared to a neutral state. Study 4, and its replication, showed that inducing gratitude causally increased smoking cessation behavior, as evidenced by enrollment in a web-based cessation intervention. Self-reported gratitude mediated the effects in both experimental studies. Finally, Study 5 found that current antismoking messaging campaigns by the US Centers for Disease Control and Prevention primarily evoked sadness and compassion, but seldom gratitude. Together, our studies advance understanding of positive emotion effects on appetitive risk behaviors; they also offer practical implications for the design of public health campaigns.

TRIM65 deficiency alleviates renal fibrosis through NUDT21-mediated alternative polyadenylation.

Chronic kidney disease (CKD) is a major global health concern and the third leading cause of premature death. Renal fibrosis is the primary process driving the progression of CKD, but the mechanisms behind it are not fully understood, making treatment options limited. Here, we find that the E3 ligase TRIM65 is a positive regulator of renal fibrosis. Deletion of TRIM65 results in a reduction of pathological lesions and renal fibrosis in mouse models of kidney fibrosis induced by unilateral ureteral obstruction (UUO)- and folic acid. Through screening with a yeast-hybrid system, we identify a new interactor of TRIM65, the mammalian cleavage factor I subunit CFIm25 (NUDT21), which plays a crucial role in fibrosis through alternative polyadenylation (APA). TRIM65 interacts with NUDT21 to induce K48-linked polyubiquitination of lysine 56 and proteasomal degradation, leading to the inhibition of TGF-β1-mediated SMAD and ERK1/2 signaling pathways. The degradation of NUDT21 subsequently altered the length and sequence content of the 3'UTR (3'UTR-APA) of several pro-fibrotic genes including Col1a1, Fn-1, Tgfbr1, Wnt5a, and Fzd2. Furthermore, reducing NUDT21 expression via hydrodynamic renal pelvis injection of adeno-associated virus 9 (AAV9) exacerbated UUO-induced renal fibrosis in the normal mouse kidneys and blocked the protective effect of TRIM65 deletion. These findings suggest that TRIM65 promotes renal fibrosis by regulating NUDT21-mediated APA and highlight TRIM65 as a potential target for reducing renal fibrosis in CKD patients.

Inhibitory activity of Alpinia galanga (Kulanjan) against pathogenic bacteria

Infectious disease are the world’s leading cause of premature deaths, killing almost 50 000 people every day. With the continuous use of antibiotics microbes have become resistant. This has created immense clinical problems in the treatment of infectious diseases. Therefore, there is a need to develop alternative antimicrobial drugs for the treatment of infectious diseases. Plant materials remain an important recourse to combat serious diseases in the world. They are used directly as therapeutic agents, as well as starting materials for the synthesis of drugs or as models for pharmacologically active compounds.The search for potent antibacterial agents has now been shifted to plants. One approach is to screen local medicinal plants for possible antimicrobial properties. According to WHO (1993), 80% of the world’s population is dependent on the traditional medicine and a major part of the traditional therapies involves the use of plant extracts or their active constituents. Yet a scientific study of plants to determine their antimicrobial active compounds is a comparatively new field. There are many published reports on the effectiveness of traditional herbs against pathogenic bacteria, viruses and fungi and as a result plants are still recognized as the bedrock for modern medicine to treat infectious diseases. Keeping in view of the importance of herbs traditionally used for the treatment of infectious diseases, this study is designed to evaluate the antimicrobial activity of Alpinia galanga used in the Indian system of medicine for the treatment various diseases. Results showed broad spectrum antimicrobial activity of Methanolic extract of Alpinia galanga roots.

Future Horizons: The Potential Role of Artificial Intelligence in Cardiology.

Cardiovascular diseases (CVDs) are the leading cause of premature death and disability globally, leading to significant increases in healthcare costs and economic strains. Artificial intelligence (AI) is emerging as a crucial technology in this context, promising to have a significant impact on the management of CVDs. A wide range of methods can be used to develop effective models for medical applications, encompassing everything from predicting and diagnosing diseases to determining the most suitable treatment for individual patients. This literature review synthesizes findings from multiple studies that apply AI technologies such as machine learning algorithms and neural networks to electrocardiograms, echocardiography, coronary angiography, computed tomography, and cardiac magnetic resonance imaging. A narrative review of 127 articles identified 31 papers that were directly relevant to the research, encompassing a broad spectrum of AI applications in cardiology. These applications included AI models for ECG, echocardiography, coronary angiography, computed tomography, and cardiac MRI aimed at diagnosing various cardiovascular diseases such as coronary artery disease, hypertrophic cardiomyopathy, arrhythmias, pulmonary embolism, and valvulopathies. The papers also explored new methods for cardiovascular risk assessment, automated measurements, and optimizing treatment strategies, demonstrating the benefits of AI technologies in cardiology. In conclusion, the integration of artificial intelligence (AI) in cardiology promises substantial advancements in diagnosing and treating cardiovascular diseases.

Defatting of donor transplant livers during normothermic perfusion—a randomised clinical trial: study protocol for the DeFat study

BackgroundLiver disease is the third leading cause of premature death in the UK. Transplantation is the only successful treatment for end-stage liver disease but is limited by a shortage of suitable donor organs. As a result, up to 20% of patients on liver transplant waiting lists die before receiving a transplant. A third of donated livers are not suitable for transplant, often due to steatosis. Hepatic steatosis, which affects 33% of the UK population, is strongly associated with obesity, an increasing problem in the potential donor pool. We have recently tested defatting interventions during normothermic machine perfusion (NMP) in discarded steatotic human livers that were not transplanted. A combination of therapies including forskolin (NKH477) and L-carnitine to defat liver cells and lipoprotein apheresis filtration were investigated. These interventions resulted in functional improvement during perfusion and reduced the intrahepatocellular triglyceride (IHTG) content. We hypothesise that defatting during NMP will allow more steatotic livers to be transplanted with improved outcomes.MethodsIn the proposed multi-centre clinical trial, we will randomly assign 60 livers from donors with a high-risk of hepatic steatosis to either NMP alone or NMP with defatting interventions. We aim to test the safety and feasibility of the defatting intervention and will explore efficacy by comparing ex-situ and post-reperfusion liver function between the groups. The primary endpoint will be the proportion of livers that achieve predefined functional criteria during perfusion which indicate potential suitability for transplantation. These criteria reflect hepatic metabolism and injury and include lactate clearance, perfusate pH, glucose metabolism, bile composition, vascular flows and transaminase levels. Clinical secondary endpoints will include proportion of livers transplanted in the two arms, graft function; cell-free DNA (cfDNA) at follow-up visits; patient and graft survival; hospital and ITU stay; evidence of ischemia-reperfusion injury (IRI); non-anastomotic biliary strictures and recurrence of steatosis (determined on MRI at 6 months).DiscussionThis study explores ex-situ pharmacological optimisation of steatotic donor livers during NMP. If the intervention proves effective, it will allow the safe transplantation of livers that are currently very likely to be discarded, thereby reducing waiting list deaths.Trial registrationISRCTN ISRCTN14957538.

Cardiac manifestations of Fabry disease in G3Stg/GlaKO and GlaKO mouse models-Translation to Fabry disease patients.

Fabry disease (FD) is an X-linked disorder of glycosphingolipid metabolism caused by mutations in the GLA gene encoding alpha-galactosidase A (α-Gal). Loss of α-Gal activity leads to progressive lysosomal accumulation of α-Gal substrate, predominately globotriaosylceramide (Gb3) and its deacylated derivative globotriaosylsphingosine (lyso-Gb3). FD manifestations include early onset neuropathic pain, gastrointestinal symptoms, and later onset life-threatening renal, cardiovascular and cerebrovascular disorders. Current treatments can preserve kidney function but are not very effective in preventing progression of cardiovascular pathology which remains the most common cause of premature death in FD patients. There is a significant need for a translational model that could be used for testing cardiac efficacy of new drugs. Two mouse models of FD have been developed. The α-Gal A-knockout (GlaKO) model is characterized by progressive tissue accumulation of Gb3 and lyso-Gb3 but does not develop any Fabry pathology besides mild peripheral neuropathy. Reports of minor cardiac function abnormalities in GlaKO model are inconsistent between different studies. Recently, G3Stg/GlaKO was generated by crossbreeding GlaKO with transgenic mice expressing human Gb3 synthase. G3Stg/GlaKO demonstrate higher tissue substrate accumulation and develop cellular and tissue pathologies. Functional renal pathology analogous to that found in early stages of FD has also been described in this model. The objective of this study is to characterize cardiac phenotype in GlaKO and G3Stg/GlaKO mice using echocardiography. Longitudinal assessments of cardiac wall thickness, mass and function were performed in GlaKO and wild-type (WT) littermate controls from 5-13 months of age. G3Stg/GlaKO and WT mice were assessed between 27-28 weeks of age due to their shortened lifespan. Several cardiomyopathy characteristics of early Fabry pathology were found in GlaKO mice, including mild cardiomegaly [up-to-25% increase in left ventricular (LV mass)] with no significant LV wall thickening. The LV internal diameter was significantly wider (up-to-24% increase at 9-months), when compared to the age-matched WT. In addition, there were significant increases in the end-systolic, end-diastolic volumes and stroke volume, suggesting volume overload. Significant reduction in Global longitudinal strain (GLS) measuring local myofiber contractility of the LV was also detected at 13-months. Similar GLS reduction was also reported in FD patients. Parameters such as ejection fraction, fractional shortening and cardiac output were either only slightly affected or were not different from controls. On the other hand, some of the cardiac findings in G3Stg/GlaKO mice were inconsistent with Fabry cardiomyopathy seen in FD patients. This could be potentially an artifact of the Gb3 synthase overexpression under a strong ubiquitous promoter. In conclusion, GlaKO mouse model presents mild cardiomegaly, mild cardiac dysfunction, but significant cardiac volume overload and functional changes in GLS that can be used as translational biomarkers to determine cardiac efficacy of novel treatment modalities. The level of tissue Gb3 accumulation in G3Stg/GlaKO mouse more closely recapitulates the level of substrate accumulation in FD patients and may provide better translatability of the efficacy of new therapeutics in clearing pathological substrates from cardiac tissues. But interpretation of the effect of treatment on cardiac structure and function in this model should be approached with caution.

Determinants/Predictors of QT Abnormalities in Patients on Psychotropic Medications in a Nigerian Tertiary Hospital.

Cardiovascular disease is a major global burden and a leading cause of premature death among patients with severe mental illness. Over time, research and clinical practice have paid increased attention to the impact of psychiatric medications on cardiac repolarization. In a resource-limited setting, it is common for psychotropic medications to be initiated and maintained in an outpatient setting without baseline or follow up ECG. This study evaluated the determinants and predictors of QT abnormalities among patient taking psychotropic drugs. We conducted a cross-sectional study in a population of 150 psychiatric patients on psychotropics and 75 controls. We studied the effects of various psychotropic drugs on QT dispersion (QTd) and corrected QT interval (QTc) as well as correlation with the types and dosages of psychotropic drugs used. All the subjects had detailed clinical examination and resting electrocardiogram (ECG) at 25mm/sec done. QTc was determined using Bazett formula and QTd was determined by subtracting shortest from longest QT in 12-lead ECG. The prevalence of prolonged QTc and QTd as well as the mean QTc and QTd were significantly higher in patients than the control group. The mean QTc was significantly higher in patient on typical antipsychotics compared to those on atypical antipsychotics. Age, heart rate and antipsychotic dose in chlorpromazine equivalent were predictors of QTc with the heart rate being the most powerful predictor among them. Psychotropic drugs use is associated with QTc and QTd prolongation with age, heart rate and antipsychotic dose as predictors of QTc.

The Role of Mitochondrial Copy Number in Neurodegenerative Diseases: Present Insights and Future Directions.

Neurodegenerative diseases are progressive disorders that affect the central nervous system (CNS) and represent the major cause of premature death in the elderly. One of the possible determinants of neurodegeneration is the change in mitochondrial function and content. Altered levels of mitochondrial DNA copy number (mtDNA-CN) in biological fluids have been reported during both the early stages and progression of the diseases. In patients affected by neurodegenerative diseases, changes in mtDNA-CN levels appear to correlate with mitochondrial dysfunction, cognitive decline, disease progression, and ultimately therapeutic interventions. In this review, we report the main results published up to April 2024, regarding the evaluation of mtDNA-CN levels in blood samples from patients affected by Alzheimer's (AD), Parkinson's (PD), and Huntington's diseases (HD), amyotrophic lateral sclerosis (ALS), and multiple sclerosis (MS). The aim is to show a probable link between mtDNA-CN changes and neurodegenerative disorders. Understanding the causes underlying this association could provide useful information on the molecular mechanisms involved in neurodegeneration and offer the development of new diagnostic approaches and therapeutic interventions.

Blockage of TMEM189 induces G2/M arrest and inhibits the growth of breast tumors

Cancer is the major cause of premature death in humans worldwide, demanding more efficient therapeutics. Aberrant cell proliferation resulting from the loss of cell cycle regulation is the major hallmark of cancer, so targeting cell cycle is a promising strategy to combat cancer. However, the molecular mechanism underlying the dysregulation of cell cycle of cancer cells remains poorly understood. TMEM189, a newly identified protein, plays roles in the biosynthesis of ethanolamine plasmalogen and the regulation of autophagy. Here, we demonstrated that the expression level of TMEM189 was negatively correlated with the survival rate of the cancer patients. TMEM189 deficiency significantly suppresses the cancer cell proliferation and migration, and causes cell cycle G2/M arrest both in vitro and in vivo. Furthermore, TMEM189 depletion suppressed the growth of breast tumors in vivo. Taken together, our work indicated that TMEM189 promotes cancer progression by regulating cell cycle G2/M transition, suggesting that it is a promising target in cancer therapy.

Hospitalization for Nonlethal Self-Harm and Premature Mortality in the 3 Years Following Adolescent Pregnancy: Population-Based Nationwide Cohort Study

(BJOG. 2023;130(9):1016–1027) Research proves a rising risk of suicidal ideation and acts in the year before and the year after giving birth. Suicide is 1 of the 2 main causes of mortality for mothers in France. There is not a solid correlation between nonlethal self-harm and suicide following childbirth, so it is difficult to predict and prevent. Adolescents are at higher risk of nonlethal self-harm, and suicide is the second cause of premature deaths in their age category. Adolescent pregnancy is tied to additional mental disorders, psychosocial problems, anxiety, depression, and eating disorders, which are all risk factors for suicidal actions. This retrospective cohort study was designed to primarily provide insights about nonlethal self-harm risks and mortality in adolescent pregnancies. Secondarily, the study aimed to evaluate the causes of deaths when possible.

An RNA-seq study in Friedreich ataxia patients identified hsa-miR-148a-3p as a putative prognostic biomarker of the disease

Friedreich ataxia (FRDA) is a life-threatening hereditary ataxia; its incidence is 1:50,000 individuals in the Caucasian population. A unique therapeutic drug for FRDA, the antioxidant Omaveloxolone, has been recently approved by the US Food and Drug Administration (FDA). FRDA is a multi-systemic neurodegenerative disease; in addition to a progressive neurodegeneration, FRDA is characterized by hypertrophic cardiomyopathy, diabetes mellitus and musculoskeletal deformities. Cardiomyopathy is the predominant cause of premature death. The onset of FRDA typically occurs between the ages of 5 and 15. Given the complexity and heterogeneity of clinical features and the variability of their onset, the identification of biomarkers capable of assessing disease progression and monitoring the efficacy of treatments is essential to facilitate decision making in clinical practice. We conducted an RNA-seq analysis in peripheral blood mononuclear cells from FRDA patients and healthy donors, identifying a signature of small non-coding RNAs (sncRNAs) capable of distinguishing healthy individuals from the majority of FRDA patients. Among the differentially expressed sncRNAs, microRNAs are a class of small non-coding endogenous RNAs that regulate posttranscriptional silencing of target genes. In FRDA plasma samples, hsa-miR-148a-3p resulted significantly upregulated. The analysis of the Receiver Operating Characteristic (ROC) curve, combining the circulating expression levels of hsa-miR-148a-3p and hsa-miR-223-3p (previously identified by our group), revealed an Area Under the Curve (AUC) of 0.86 (95%, Confidence Interval 0.77–0.95; p-value < 0.0001). An in silico prediction analysis indicated that the IL6ST gene, an interesting marker of neuroinflammation in FRDA, is a common target gene of both miRNAs. Our findings support the evaluation of combined expression levels of different circulating miRNAs as potent epi-biomarkers in FRDA. Moreover, we found hsa-miR-148a-3p significantly over-expressed in Intermediate and Late-Onset Friedreich Ataxia patients’ group (IOG and LOG, respectively) compared to healthy individuals, indicating it as a putative prognostic biomarker in this pathology.

The relationship between mindfulness, personality factors and perfectionism with anger in hypertensive patients

Background and Objectives: High blood pressure is one of the most common and important threats to human health and is the main cause of premature death all over the world. High blood pressure is caused by psycho-physiological factors. The present study was conducted with the aim of determining the relationship between mindfulness, personality factors and perfectionism with anger in high blood pressure patients. Material and Methods: This research was a descriptive-cross-sectional and correlational study. The statistical population was the patients with high blood pressure who referred to the medical centers of Tabriz city in 1401. The sample size of the research using Cochran's formula was 184 people who were selected by available method. Research tools were Multidimensional Perfectionism Questionnaire, Spielberger State-Trait Anger Questionnaire, Revised NEO Questionnaire (short form), Brown and Ryan Mindfulness Assessment Scale. Data were analyzed by correlation and regression tests with SPSS-25 software. Results: The results showed that there is a negative and significant relationship between mindfulness and anger in high blood pressure patients (P&lt;0/05). Among the personality factors, narcissism and conscientiousness have a positive and significant relationship with anger. There is a negative and significant relationship between extroversion, flexibility and agreeableness with anger in high blood pressure patients (P &lt; 0/05). There is a positive and significant relationship between self-oriented, other-oriented and community-oriented perfectionism with anger in high blood pressure patients (P&lt; 0/05). Also, mindfulness, personality factors and perfectionism can predict anger (P&lt;0/05). Conclusion: The results showed that there is a relationship between mindfulness, personality factors and perfectionism with anger. Therefore, by identifying psychological variables such as mindfulness, personality factors and perfectionism and its relationship with anger, blood pressure reduction in patients can be helped.

Theoretical Exploration of the Antioxidant Activity, Chemopreventive, and Antineoplastic Potentials of Molecules Present in Morinda lucida, Momordica charantia, and Vernonanthura polyanthes

Cancer is one of the leading causes of death worldwide and one of the top four causes of premature death in most countries. Several studies have shown that secondary metabolites found in medicinal plants have anticancer, antimutagenic, anti-genotoxic, and chemopreventive effects. Ethnobotany knowledge points to Morinda lucida, Momordica charantia, and Vernonanthura polyanthes as anticancer plants, turning them into promising candidates for cancer treatment. This study analyzed M. lucida, M. charantia, and V. polyanthes compounds to identify potential antioxidant, chemopreventive, and anticancer agents through in silico analysis. We performed pharmacokinetics, biological activities, and toxicological predictions besides molecular docking. Theoretical calculations on thermodynamic grounds of the antioxidant properties were determined using density functional theory. The molecules damnacanthal, momordicin I, and quercetin-3-[Formula: see text]-rutinoside identified in M. lucida, M. charantia, and V. polyanthes, respectively, presented good anticancer potential and were chosen for the molecular docking study and DFT calculations. According to Lipinski’s criteria, damnacanthal, momordicin I, and quercetin-3-[Formula: see text]-rutinoside were classified as potential drugs, especially for the pharmacokinetics criteria. Damnacanthal and momordicin I had high absorption in the gastrointestinal treatment, while quercetin-3-[Formula: see text]-rutinoside had low absorption. These compounds also demonstrated antineoplastic, antimutagenic, and cancer-preventive activity, according to the in silico analysis. In this sense, damnacanthal, momordicin I, and quercetin-3-[Formula: see text]-rutinoside were chosen to test their potential interactions with the beta estrogen receptor, vascular endothelial growth factor receptor 2, and xanthine dehydrogenase, respectively, and intermolecular interactions were determined. Regarding the antioxidant potential of the structures, two different mechanisms were scrutinized with the help of their respective molecular descriptors, such as hydrogen atom transfer (HAT) and one-electron transfer (ET). In conclusion, this computational study revealed that damnacanthal, momordicin I, and quercetin-3-[Formula: see text]rutinoside are promising chemoprotective and anticancer molecules with favorable pharmacokinetics and toxicological properties.

Translating global evidence into local implementation through technical assistance: a realist evaluation of the Bloomberg philanthropies initiative for global Road safety

BackgroundTraffic-related crashes are a leading cause of premature death and disability. The safe systems approach is an evidence-informed set of innovations to reduce traffic-related injuries and deaths. First developed in Sweden, global health actors are adapting the model to improve road safety in low- and middle-income countries via technical assistance (TA) programs; however, there is little evidence on road safety TA across contexts. This study investigated how, why, and under what conditions technical assistance influenced evidence-informed road safety in Accra (Ghana), Bogotá (Colombia), and Mumbai (India), using a case study of the Bloomberg Philanthropies Initiative for Global Road Safety (BIGRS).MethodsWe conducted a realist evaluation with a multiple case study design to construct a program theory. Key informant interviews were conducted with 68 government officials, program staff, and other stakeholders. Documents were utilized to trace the evolution of the program. We used a retroductive analysis approach, drawing on the diffusion of innovation theory and guided by the context-mechanism-outcome approach to realist evaluation.ResultsTA can improve road safety capabilities and increase the uptake of evidence-informed interventions. Hands-on capacity building tailored to specific implementation needs improved implementers’ understanding of new approaches. BIGRS generated novel, city-specific analytics that shifted the focus toward vulnerable road users. BIGRS and city officials launched pilots that brought evidence-informed approaches. This built confidence by demonstrating successful implementation and allowing government officials to gauge public perception. But pilots had to scale within existing city and national contexts. City champions, governance structures, existing political prioritization, and socio-cultural norms influenced scale-up.ConclusionThe program theory emphasizes the interaction of trust, credibility, champions and their authority, governance structures, political prioritization, and the implement-ability of international evidence in creating the conditions for road safety change. BIGRS continues to be a vehicle for improving road safety at scale and developing coalitions that assist governments in fulfilling their role as stewards of population well-being. Our findings improve understanding of the complex role of TA in translating evidence-informed interventions to country-level implementation and emphasize the importance of context-sensitive TA to increase impact.

Optimization of Phloretin-loaded Nanospanlastics for Targeting of FAS/SREBP1c/AMPK/ OB-Rb Signaling Pathway in HFD-induced Obesity.

Obese patients are at increased risk for CVD, which is the main cause of premature death and has been a major cause of disability and ill health in recent years. PTN, a natural dihydrochalcone flavonoid, has a variety of pharmacological characteristics. This article aimed to prepare PTN-NSLs to evaluate their anti-obesity activity. Morphology, Particle size, zeta potential, UV-vis, entrapment efficiency, FT-IR spectra, and an in vitro release study of PTN-NSLs were described. PTN-NSLs were also tested for their anti-obesity properties in obese rats. The LD50 of PTN-NSLs was calculated, as was the 1/20 LD50 prepared for the treatment of obese rats. Also, the level of glycemic, oxidative stress and inflammatory biomarkers were estimated in the obese rat's model. The synthesized PTN-NSLs were uniform, spherically shaped, and well dispersed with no aggregation noted, with a size range of 114.06 ± 8.35 nm. The measured zeta potential value of PTN-NSLs was -32.50.8 mv. Also, the UV spectra of PTN and PTN-NSLs have strong absorption at 225 and 285 nm. Also, the LD50 of PTN-NSLs was found to be 2750 mg/kg.b.w. Moreover, administrating obese rats with PTN-NSLs resulted in improved glycemic features as well as GSH, SOD, GPx, GR, IL10, TBARs, and IL-6 levels, as well as attenuated FAS, SREBP1c, AMPK, ACO, CPT1, and OB-Rb gene expression. Administration of PTN-NSLs significantly attenuated the levels of glycemic, oxidative stress, and inflammatory biomarkers. The biochemical and PCR findings are aided by histological investigations. Also, the present findings imply that PTN-NSLs might be a promising pharmacological tool for the treatment of obesity-related diseases.
