Poor performance on a composite mental health index predicts low handgrip strength and physical disabilities in Europe.

Objectives: Poor mental health affects physical health, but the combined effects of mental comorbidities on handgrip strength (HGS), fatigue, and activities of daily living are poorly known. We investigated the combined effects of anxiety, depression, and dementia on handgrip strength (HGS), fatigue, and activities of daily living.

Methods: A composite mental health index (CMHI) comprised of anxiety, depression, and dementia was created and used to predict future onset of low HGS (men ≤ 27 kg, women ≤ 16 kg), fatigue, and four physical difficulties (dressing, walking, climbing stairs, rising from a chair) in 64,244 European adults aged ≥50 from 27 countries using 2021-2022 Survey of Health, Ageing, and Retirement in Europe (SHARE) data.

The simple task of lifting five kilograms serves as a predictor of age-related disorders in old adults.

Muscle weakness is a risk factor for multiple diseases. However, most protocols to assess muscle weakness require clinical settings. A difficulty lifting 5 kg may be a simple measure of muscle weakness in domestic settings.

Cystatin-c / total cholesterol ratio as a predictor of probable sarcopenia in geriatric population from 12 European countries.

Background: A low handgrip strength (HGS) is associated with several diseases in older adults. However, predictive biomarkers of future low HGS are poorly known. We investigated the prognostic efficacy of the ratio of plasma cystatin-c and total cholesterol (CT ratio) levels for predicting future low HGS in Europe.

Accelerometery 24-hour movement behaviours and health markers in the European old population: iso-temporal substitution regression.

Background: The amount of physical activity, sleep, and sedentary behaviour affect several age-related diseases. However, no relevant study about their associations with cardiovascular and musculoskeletal diseases from European older adults is known.

Methods: We investigated the associations of the volumes of physical activity, sleep, and sedentary behaviour with low handgrip strength (HGS), heart attack, hip fracture, rheumatoid arthritis, stroke, and osteoarthritis among European older adults (age ≥ 50 years, n = 819) from ten countries using cross-sectional data from the Survey of Health, Ageing, and Retirement in Europe (SHARE) conducted between 2019 and 2021.

Navigating the impact of remittances on environmental quality in Africa: The crucial role of institutional quality.

The Sub-Saharan African (SSA) region remains the world's largest recipient of remittances. Due to growing concerns over climate change issues, recent studies have examined how these financial flows have affected environmental quality. Sundry variables were controlled in such studies concerning the remittances-environment nexus, including institutional quality.

Predictors of the onset of low handgrip strength in Europe: a longitudinal study of 42,183 older adults from 15 countries.

Objectives: A low handgrip strength (HGS) is a significant risk factor for multiple diseases. However, most relevant studies investigate the complications of a low HGS, while the risk potential of causative factors of low HGS remain poorly characterized.

Methods: We investigated the potentials of quality of life, depression, dyslipidaemia, diabetes mellitus, cancer, Alzheimer's disease, stroke, frailty, and difficulties performing daily activities in predicting low HGS (≤ 27 kg for men, ≤ 16 kg for women) in European older adults aged 50 or above from 15 countries (n = 42,183).

Pathway to environmental sustainability: Assessing the role of productive capacity, remittances, and uncertainty in sub-Saharan Africa.

Unlike previous studies that have examined the association between different economic development parameters and environmental sustainability, the present study utilised an index of productive capacity to offer an in-depth understanding of the ecological impact of improving a nation's productive resources. It also emphasised the importance of remittances in reducing environmental degradation in uncertain economic and political environments. This study applied the system GMM technique and an advanced panel quantile regression technique to 36 Sub-Saharan Africa (SSA) region countries from 2000 to 2022.

Predictors of hip fracture in 15 European countries: a longitudinal study of 48,533 geriatric adults using SHARE dataset.

Unlabelled: We investigated the risk factors for hip fracture in 48,533 European older adults for 8 years from 2013 onward. We identified female gender, age above 80, low handgrip strength, and depression as significant risk factors for hip fracture. Our findings may help identify high-risk populations for hip fractures in pre-clinical settings.

Unleashing sustainability in uncertain times: Can we leverage economic complexity, uncertainty, and remittances to combat environmental degradation?

Rapid economic growth and human activities have seriously damaged the environment and hindered the achievement of Sustainable Development Goals (SDGs). Hence, this study aims to explore the impact of economic complexity, uncertainty, and remittance on environmental degradation in 134 countries from 2000 to 2022. In addition, it examines whether uncertainty moderates the relationship between remittance and environmental degradation.

Is there a trade-off between ICTs and ecological systems in Africa? Evidence from heterogeneous panel methods robust to cross-sectional dependence.

Among the UN's 17 Sustainable Development Goals (SDGs), increasing infrastructure resilience (SDG) and combating climate change and its impacts (SDG) have been vital goals. Growing evidence supports the presence of a trade-off between expanding information and communication technologies (ICT) infrastructure and maintaining the quality of the environment. Based on an ICT index and the ecological footprint, the present study reinvestigated the influence of ICT on environmental quality for a sample of African countries, where ICT services have substantially increased over the past decades.

Role of Phytosterols in Cancer Prevention and Treatment.

Plant sterols or phytosterols have been shown to be effective in improving blood lipid profile and thereby protective against cardiovascular disease. In addition to their cardioprotective effects, phytosterols have gained more insight for their protective effect against various forms of cancer. Phytosterols have been reported to alleviate cancers of breast, prostate, lung, liver, stomach and ovary.

L-arginine and nitric oxide in CNS function and neurodegenerative diseases.

One of the main functions of L-arginine (ARG) is the synthesis of nitric oxide (NO). NO is an important regulator of physiological processes in the central nervous system (CNS). NO promotes optimal cerebral blood flow, consolidates memory processes, facilitates long-term potentiation, maintains sleep-wake cycles, and assists in normal olfaction.

A prospective randomised comparative study of endoscopic band ligation versus injection sclerotherapy of bleeding internal haemorrhoids in patients with liver cirrhosis.

Background And Study Aims: Bleeding internal haemorrhoids are common and used to be treated surgically with too many complications. Endoscopic therapy is trying to take the lead. Sclerotherapy and rubber band ligation are the candidates to replace surgical therapy especially in patients with liver cirrhosis.

Vitamin D and multiple sclerosis.

Multiple sclerosis (MS) is an inflammatory disease of the central nervous system and characterized by neurological and cognitive manifestations. The disease is more common in populations living in high altitudes with low sun exposure, women more than men, and certain ethnic backgrounds more than others. The etiology of MS is yet unknown, although several factors have been implicated in its development.

Statin therapy depresses fat metabolism in older individuals.

Objective: Statins (3-hydroxy-3-methylglutaryl coenzyme A [HMG CoA] reductase inhibitors) reduce blood lipoproteins and reduce the risk of cardiovascular events. However, they may reduce fat metabolism. This study tested the hypothesis that total body fat oxidation is reduced by statins in older subjects and the reduction is not due to substrate availability.

Regulatory approval of plant sterols in Canada: implications for health care and clinical practice.

Health Canada's recent approval of plant sterols as food ingredients to decrease low-density lipoprotein cholesterol (LDL-C) is believed to be a significant step toward improving Canadians' cardiovascular health and reducing the economic burden of heart disease. When dyslipidemic patients consume plant sterols at a recommended daily dose of 2 g, they can reduce LDL-C by 10% to 15%, with no deleterious effects on high-density lipoprotein cholesterol. A 10% LDL-C reduction in response to plant sterol consumption is projected to reduce heart disease risk by 25%.

Vitamin d and metabolic syndrome risk factors: evidence and mechanisms.

The metabolic syndrome develops in an individual with any three of the following risk factors: obesity, diabetes, inflammation, hypertension, dyslipidemia, and thrombosis. Recent evidence suggests that vitamin D may play a role in the development of some of these risk factors. The metabolic syndrome is more common in western societies than the underdeveloped countries.

β-Sitosterol down-regulates some pro-inflammatory signal transduction pathways by increasing the activity of tyrosine phosphatase SHP-1 in J774A.1 murine macrophages.

The objective of the present study was to examine the anti-inflammatory effects of β-sitosterol (SIT), the most common phytosterol in the diet, and to investigate its involvement in NF-κB and STAT1 pathways as potential mechanisms. In addition, the activity of the phosphatase SHP-1 as a negative modulator to these pathways, was investigated. Utilizing murine J774A.

Phytosterols ameliorate clinical manifestations and inflammation in experimental autoimmune encephalomyelitis.

Introduction: Using experimental autoimmune encephalomyelitis (EAE), an animal model for multiple sclerosis (MS), the objective of this study was to examine the effect of phytosterol (PS) administration on inflammation-based EAE development.

Methods: Female SJL mice were orally administered PS prior to disease induction and maintained throughout the experiment. EAE was induced with antigenic peptide (PLP(131-155)).

Curcumin and obesity: evidence and mechanisms.

The incidence of obesity is increasing worldwide and is hence considered a major public health concern. Obesity underlies the development of several metabolic complications including cardiovascular diseases, diabetes, and inflammation. Research on ways to slow the development of obesity have traditionally focused on dietary and lifestyle modifications such as restricting caloric intake and increasing physical activity.

Modulation of signal transduction in cancer cells by phytosterols.

Phytosterols are biofactors found enriched in plant foods such as seeds, grains, and legumes. Their dietary consumption is associated with numerous health benefits. Epidemiologic and experimental animal studies indicate that phytosterols are cancer chemopreventive agents particularly against cancers of the colon, breast, and prostate.

Effect of vitamin D and β-sitosterol on immune function of macrophages.

Among the many functions of vitamin D (VD) is its role in the immunomodulation of macrophage. As VD deficiency is a wide-spread nutritional problem, there is a tendency for the public to overdose with vitamin D supplementation which can result in hypercalcemia and several associated disorders. The present study was designed to investigate the possibility that combining low doses of vitamin D with β-sitosterol (SIT), a common phytosterol in the diet without toxicity, enhances the efficacy of the vitamin.

Comparison of the immunomodulatory effects of the plant sterol beta-sitosterol to simvastatin in peripheral blood cells from multiple sclerosis patients.

Statins as hypocholesterolimic drugs have recently shown to have ant-inflammatory properties and thus are being assessed for the treatment of multiple sclerosis (MS). Dietary phytosterols such as beta-sitosterol (SIT) are also hypocholesterolemic compounds and from preliminary studies they appear to have also anti-inflammatory properties. In this communication, we report on studies to investigate the immunomodulatory effects of SIT on proliferation and release of key cytokines from peripheral blood mononuclear cells (PBMC) of MS patients.

Phytosterols as anticancer compounds.

Phytochemicals have been proposed to offer protection against a variety of chronic ailments including cardiovascular diseases, obesity, diabetes, and cancer. As for cancer protection, it has been estimated that diets rich in phytochemicals can significantly reduce cancer risk by as much as 20%. Phytosterols are specific phytochemicals that resemble cholesterol in structure but are found exclusively in plants.
