Effects of Bilberry Supplementation on Metabolic and Cardiovascular Disease Risk
Metabolic syndrome is a cluster of interrelated conditions that is associated with an increased risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). Oxidative stress may impair normal physiological functions, leading to various illnesses. T2DM is considered to be associated with increased oxidative stress, inflammation, and dyslipidemia, which may play a significant role in the development of cardiovascular complications, cancer and vision loss through cataracts and retinopathy. While conventional therapies are a cornerstone for the management of the major risk factors of metabolic syndrome, increasing antioxidant defense by increasing intake of antioxidant-rich foods may improve long term prospects in CVD, obesity and T2DM. Bilberry (Vaccinium myrtillus L.) is one of the richest natural sources of anthocyanins which give berries their red/purple/blue coloration. Anthocyanins are powerful antioxidants and are reported to play an important role in the prevention of metabolic disease and CVD as well as cancer and other conditions. This review focuses on the potential effects of bilberry supplementation on metabolic and cardiovascular risk factors. Although there is evidence to support the use of bilberry supplementation as part of a healthy diet, the potential benefits from the use of bilberry supplementation in patients with T2DM or CVD needs to be clarified in large clinical trials.

Insulin resistance surrogates predict hypertension plus hyperuricemia
Aims/Introduction To compare the association of hypertension plus hyperuricemia with four insulin resistance surrogates, including glucose and triglycerides (TyG index), TyG index with body mass index (TyG‐BMI), the ratio of triglycerides divided by high‐density lipoprotein cholesterol (TG/HDL‐C) and metabolic score for insulin resistance (METS‐IR). Materials and Methods Data from a cross‐sectional epidemiological study enrolling a representative population sample aged ≥65 years were used to calculate the four indexes. The association with hypertension plus hyperuricemia and insulin resistance surrogates was examined with multivariate logistic regression and receiver operating characteristic. Results A total of 4,352 participants were included, including 93 (2.1%) patients with hyperuricemia alone, 2,875 (66.1%) with hypertension alone and 587 (13.5%) with hypertension plus hyperuricemia. Mutivariate logistic regression showed that TyG index, TyG‐BMI, TG/HDL‐C and METS‐IR were all significantly correlated with hyperuricemia, hypertension and hypertension plus hyperuricemia. Compared with the lowest quartile, the odds ratios (OR) of the highest quartile of the four indicators for hypertension plus hyperuricemia were TyG index: OR 6.39 (95% confidence interval [CI] 4.17–9.78); TyG‐BMI: OR 8.54 (95% CI 5.58–13.09); TG/HDL‐C: OR 7.21 (95% CI 4.72–11.01); METS‐IR: OR 9.30 (95% CI 6.00–14.43), respectively. TyG‐BMI and METS‐IR had moderate discriminative abilities for hypertension plus hyperuricemia and the AUC values were 0.72 (95% CI 0.70–0.74) and 0.73 (95% CI 0.70–0.75). Conclusions The present study suggested that TyG index, TyG‐BMI, TG/HDL‐C and METS‐IR had a significant correlation with hypertension plus hyperuricemia, and TyG‐BMI and METS‐IR had discriminative abilities for hypertension plus hyperuricemia. Our study suggested that glucose and triglycerides (TyG index), TyG index with body mass index, the ratio of triglycerides divided by high‐density lipoprotein cholesterol and metabolic score for insulin resistance had a significant correlation with hypertension plus hyperuricemia, and TyG index with body mass index and metabolic score for insulin resistance had discriminative abilities for hypertension plus hyperuricemia.

The beneficial effects of Ganoderma lucidum on cardiovascular and metabolic disease risk
Various herbal medicines are thought to be useful in the management of cardiometabolic disease and its risk factors. Ganoderma lucidum (Curtis) P. Karst. (Ganodermataceae), also known as Lingzhi, has received considerable attention for various indications, including some related to the prevention and treatment of cardiovascular and metabolic disease by ameliorating major cardiovascular risk factors.
This review focuses on the major studies of the whole plant, plant extract, and specific active compounds isolated from G. lucidum in relation to the main risk factors for cardiometabolic disease.
References from major databases including PubMed, Web of Science, and Google Scholar were compiled. The search terms used were Ganoderma lucidum, Lingzhi, Reishi, cardiovascular, hypoglycaemic, diabetes, dyslipidaemia, antihypertensive, and anti-inflammatory.
A number of in vitro studies and in vivo animal models have found that G. lucidum possesses antioxidative, antihypertensive, hypoglycaemic, lipid-lowering, and anti-inflammatory properties, but the health benefits in clinical trials are inconsistent. Among these potential health benefits, the most compelling evidence thus far is its hypoglycaemic effects in patients with type 2 diabetes or hyperglycaemia.
The inconsistent evidence about the potential health benefits of G. lucidum is possibly because of the use of different Ganoderma formulations and different study populations. Further large controlled clinical studies are therefore needed to clarify the potential benefits of G. lucidum preparations standardised by known active components in the prevention and treatment of cardiometabolic disease.

How the EU's Taxonomy Combats Greenwashing
Tomlinson argues that the European Union's taxonomy offers a clearer, more credible framework for identifying truly sustainable business activities than traditional ESG (environmental, social, and governance) metrics. Created as part of the EU's Green Deal, the taxonomy defines what counts as \"green\" using science-based criteria across six environmental objectives, such as climate change mitigation and pollution control. Unlike ESG scores, which vary across providers and assess companies holistically, the taxonomy evaluates individual business activities. This gives investors a more accurate view of how much of a company's operations--and revenue or capital spending--is genuinely sustainable. The taxonomy also exposes greenwashing by requiring firms to disclose how their green claims align with actual performance and investment. Although implementing the taxonomy poses challenges, it's expected to impact global businesses, including many US firms, due to the EU's regulatory influence.

Patient preferences for ambulatory blood pressure monitoring devices: Wrist-type or arm-type?
Ambulatory blood pressure monitoring (ABPM) is important in evaluating average 24-hour blood pressure (BP) levels, circadian rhythm, sleeping BP and BP variability but many patients are reluctant to use standard ABPM devices.
We compared two validated ABPM devices, the BPro tonometric wrist monitor and the A&D TM-2430 oscillometric upper arm monitor, for agreement of recordings and acceptability in 37 hypertensive patients (aged 55±9 years).
Successful BP measurements were less frequent with the wrist-type than the arm-type device during the sleeping (66.3% vs. 92.9%, P <0.01) and awake periods (56.2% vs. 86.5%, P <0.01). Comparable paired readings showed no significant difference in systolic BP but diastolic BP (DBP) values were higher with the wrist compared to the arm monitor (24-hour 89±13 vs. 85±14 mmHg, P <0.01) with similar differences awake and sleeping. Bland-Altman analysis showed some large discrepancies between individual arm and wrist monitor measurements. More patients found the wrist monitor more comfortable to use than the arm monitor.
Despite the difference in individual BP measurements and the systematic overestimation of DBP values with the BPro device, wrist monitors with good patient acceptability may be useful to facilitate ABPM in some patients to provide additional information about cardiovascular risk and response to antihypertensive therapies.

Metformin in polycystic ovary syndrome: unraveling multi-stage therapeutic mechanisms from puberty to long-term health outcomes
Polycystic ovary syndrome (PCOS) represents a prevalent endocrine disorder affecting reproductive-aged women worldwide, characterized by a variety of reproductive, metabolic, and psychological manifestations. This condition disrupts menstrual cycles and fertility, and significantly compromises quality of life, while increasing the risk of severe health consequences, including cardiovascular diseases and endometrial carcinoma. Although the precise etiology of PCOS remains elusive, genetic and environmental factors are thought to contribute to its pathogenesis. In recent years, the escalating global prevalence of PCOS has been observed, and pharmacological intervention has become the primary treatment approach. Metformin, an insulin sensitizer, has emerged as a valuable treatment option in PCOS management. Multiple studies have suggested that metformin have a positive impact on puberty problems, pregnancy complications, and long-term health outcomes in women with PCOS. However, persistent controversies surround its therapeutic efficacy and underlying molecular mechanisms. This review systematically examines the mechanisms of metformin in ameliorating PCOS-associated infertility, with particular emphasis on its pleiotropic effects across critical life stages—from pubertal development through pregnancy to long-term health outcomes, thereby providing valuable insights into the clinical application of metformin in the treatment of PCOS.

Materials development for language learning and teaching
This article reviews the literature on the relatively new field of materials development for language learning and teaching. It reports the origins and development of the field and then reviews the literature on the evaluation, adaptation, production and exploitation of learning materials. It also reviews the literature, first, on a number of controversial issues in the field, next, on electronic delivery of materials and, third, on research in materials development. It identifies gaps in the literature and makes proposals for future progress in materials development and in the research within the field. Much of the literature focuses on materials for learning English but the same principles apply to materials for learning any L2, as has been acknowledged by some of the authors whose publications focus on materials for learning other languages.
