Plain language summary
Chronic hypertension complicates ≤5 % of pregnancies, and those entering pregnancy with a pre-existing diagnosis of diabetes has a global prevalence of between 0.5 % and 2.6 %. The aim of this study was to collate the evidence around lifestyle interventions during pregnancy for women with chronic hypertension and/or pre-existing diabetes (type 1 and type 2). This study is a systematic review and meta-analysis of nine randomised controlled trials. Results show lack of clarity and data on the effect of lifestyle interventions in pregnant women with chronic hypertension and/or pre-existing diabetes, thereby exposing key gaps in the literature. Authors conclude that there is a shortage of primary interventional studies examining the effect of lifestyle interventions in high-risk pregnant populations who enter pregnancy with chronic conditions.
Abstract
BACKGROUND Pregnant people with chronic hypertension, pre-existing diabetes or both are at high risk of developing cardiovascular disease. Lifestyle interventions play an important role in disease management in non-pregnant populations. AIM: To review the existing evidence of randomised controlled trials (RCTs) that examine lifestyle interventions in pregnant people with chronic hypertension and/or pre-existing diabetes. METHODS A systematic review and narrative synthesis was conducted. Five electronic databases were searched from inception to April 2021 for RCTs evaluating antenatal lifestyle interventions in people with chronic hypertension and/or pre-existing diabetes with outcomes to include weight or blood pressure change. RESULTS Nine randomised controlled trials including 7438 pregnant women were eligible. Eight studies were mixed pregnant populations that included women with chronic hypertension and/or pre-existing diabetes. One study included only pregnant women with pre-existing diabetes. Intervention characteristics and procedures varied and targeted diet, physical activity and/or gestational weight. All studies reported weight and one study reported blood pressure change. Outcome data were frequently unavailable for the subset of women of interest, including subgroup data on important pregnancy and birth complications. Eligibility criteria were often ambiguous and baseline data on chronic hypertension was often omitted. CONCLUSION A lack of primary interventional trials examining the effect of lifestyle interventions on weight and blood pressure outcomes in pregnant populations with chronic hypertension and/or pre-existing diabetes was evident. Lifestyle modification has the potential to alter disease progression. Future trials should address the ambiguity and frequent exclusion of these important populations.

Plain language summary
Older people are at high risk of cardiovascular disease, and 90% of the risk factors can be modified, including an unhealthy diet, poor physical activity, obesity, smoking, and obesity-related comorbidities. This randomised controlled trial examined a multifactorial approach combining several lifestyle modifications in 1259 older adults between 60 and 77 years of age to reduce the risk of cardiovascular disease. Participants were randomly assigned to intensive multi-domain lifestyle intervention or regular health advice control groups. The multifactorial lifestyle intervention incorporated dietary counselling, exercise training, cognitive training, and managing CVD and metabolic risk factors. Dietary interventions included tailored strategies that considered increased consumption of fruits, berries, vegetables, whole grains, margarine, oil, and fish. Physical exercise interventions included strength training, balance exercises, and aerobic exercises. Cognitive interventions and intensive strategies to manage metabolic factors were also implemented. In the multifactorial lifestyle intervention group, cerebrovascular events were lower after two years than in the control group. In addition, cardiovascular disease and stroke incidence were lower in the elderly with a history of cardiovascular disease. Healthcare professionals can use the results from this study to understand the benefits of multifactorial lifestyle interventions on cardiovascular disease. However, there is a need for longer-term robust studies since the evidence is sparse.
Abstract
AIMS: Joint prevention of cardiovascular disease (CVD) and dementia could reduce the burden of both conditions. The Finnish Geriatric Intervention Study to Prevent Cognitive Impairment and Disability (FINGER) demonstrated a beneficial effect on cognition (primary outcome) and we assessed the effect of this lifestyle intervention on incident CVD (pre-specified secondary outcome). METHODS AND RESULTS FINGER enrolled 1259 individuals aged 60-77 years (ClinicalTrials.gov NCT01041989). They were randomized (1:1) to a 2-year multi-domain intervention with diet, physical and cognitive activity, and vascular monitoring (n = 631), or general health advice (n = 628). National registries provided data on CVD including stroke, transient ischaemic attack (TIA), or coronary heart event. During an average of 7.4 years, 229 participants (18%) had at least one CVD diagnosis: 107 in the intervention group and 122 in the control group. The incidence of cerebrovascular events was lower in the intervention than the control group: hazard ratio (HR) for combined stroke/TIA was 0.71 [95% confidence interval (CI): 0.51-0.99] after adjusting for background characteristics. Hazard ratio for coronary events was 0.84 (CI: 0.56-1.26) and total CVD events 0.80 (95% CI: 0.61-1.04). Among those with history of CVD (n = 145), the incidence of both total CVD events (HR: 0.50, 95% CI: 0.28-0.90) and stroke/TIA (HR: 0.40, 95% CI: 0.20-0.81) was lower in the intervention than the control group. CONCLUSION A 2-year multi-domain lifestyle intervention among older adults was effective in preventing cerebrovascular events and also total CVD events among those who had history of CVD.

Plain language summary
The Covid-19 pandemic has caused thousands of deaths worldwide. Being obese is associated with worse outcomes following infection with Covid-19. This review aimed to summarise the data available on the relationship between Covid-19 and obesity, and explored some of the possible reasons for this relationship. The researchers found that obesity is an independent and strong risk factor for severe infection, Intensive Care Unit (ICU) admission and death. The impact of obesity might be of particular relevance in males and in younger individuals. Long‐term complications of Covid‐19 could also be more frequent and severe in obese subjects. There are many potential mechanisms that could explain this relationship. These include the effects of obesity and related diseases such as diabetes, high blood pressure and heart disease on the immune system, lung function, vitamin D deficiency and male hormones. The researchers also discussed the possibility of fat cells acting as a possible reservoir for Covid-19 infection. Research into Covid-19 is still at a very early stage and more studies are needed.
Abstract
The COVID-19 pandemic is posing a great challenge worldwide. Its rapid progression has caused thousands of deaths worldwide. Although multiple aspects remain to be clarified, some risk factors associated with a worse prognosis have been identified. These include obesity and some of its main complications, such as diabetes and high blood pressure. Furthermore, although the possible long-term complications and psychological effects that may appear in survivors of COVID-19 are not well known yet, there is a concern that those complications may be greater in obese patients. In this manuscript, we review some of the data published so far and the main points that remain to be elucidated are emphasized.

Plain language summary
Menopause is the absence of menstruation due to the loss of ovarian activity with ageing. During this transition period, changes in hormones, primarily the decline in the oestrogen estradiol, give rise to altered lipid metabolism. An unfavourable lipid profile presents a risk for metabolic disorders, such as cardiovascular diseases and type 2 diabetes. Post-menopausal changes also lead to shifts in body fat and fat distribution, resulting in an increased tendency for central fat accumulation and obesity. Obesity is associated with insulin resistance. This susceptibility for weight accumulation is possibly also driven by the age-associated decline in skeletal muscle, which reduces metabolic energy expenditure. This review summarizes the physiology of menopause and postmenopause and the consequential impact on lipid metabolism. In addition, there is a discussion of dietary recommendations, nutritional and plant-derived compounds that could support the management of menopause associated changes in lipid levels, metabolic risk factors and obesity. The recommendations discussed include traditional healthy diets and low-calorie diets, with attention drawn to adequate protein intake. Furthermore, the role of probiotics, nutritional and plant-sourced constituents are considered, including Vitamin D, Omega-3 fatty acids, antioxidants like Vitamin A, β-carotene, Vitamin C and E, genistein, resveratrol, flavonoids, indoles and capsaicin. The authors advocate sourcing these compounds from a varied whole-foods diet, which would minimize nutrient interactions and absorption issues that can occur with supplementation. This review may be of interest to those supporting the nutritional needs of menopausal and post-menopausal women, that are experiencing or are at risk of experiencing metabolic disorders.
Abstract
Menopause is clinically diagnosed as a condition when a woman has not menstruated for one year. During the menopausal transition period, there is an emergence of various lipid metabolic disorders due to hormonal changes, such as decreased levels of estrogens and increased levels of circulating androgens; these may lead to the development of metabolic syndromes including cardiovascular diseases and type 2 diabetes. Dysregulation of lipid metabolism affects the body fat mass, fat-free mass, fatty acid metabolism, and various aspects of energy metabolism, such as basal metabolic ratio, adiposity, and obesity. Moreover, menopause is also associated with alterations in the levels of various lipids circulating in the blood, such as lipoproteins, apolipoproteins, low-density lipoproteins (LDLs), high-density lipoproteins (HDL) and triacylglycerol (TG). Alterations in lipid metabolism and excessive adipose tissue play a key role in the synthesis of excess fatty acids, adipocytokines, proinflammatory cytokines, and reactive oxygen species, which cause lipid peroxidation and result in the development of insulin resistance, abdominal adiposity, and dyslipidemia. This review discusses dietary recommendations and beneficial compounds, such as vitamin D, omega-3 fatty acids, antioxidants, phytochemicals-and their food sources-to aid the management of abnormal lipid metabolism in postmenopausal women.
