Plain language summary
Coronavirus disease 2019 (COVID-19) is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which was also previously known as 2019-nCoV. This study is a systematic literature review which summarises the findings on the current knowledge of COVID-19 in children. The review includes 45 scientific papers and letters. Results showed that children have so far accounted for 1%-5% of diagnosed cases. Children often are asymptomatic, have milder disease than adults, and deaths have been extremely rare. Diagnostic findings have been similar to adults, with fever and respiratory symptoms being prevalent. Authors conclude that the disease course in paediatric COVID-19 was milder than in adults, children had a better prognosis and deaths were extremely rare.
Abstract
AIM: The coronavirus disease 2019 (COVID-19) pandemic has affected hundreds of thousands of people. Data on symptoms and prognosis in children are rare. METHODS A systematic literature review was carried out to identify papers on COVID-19, which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), using the MEDLINE and Embase databases between January 1 and March 18, 2020. RESULTS The search identified 45 relevant scientific papers and letters. The review showed that children have so far accounted for 1%-5% of diagnosed COVID-19 cases, they often have milder disease than adults and deaths have been extremely rare. Diagnostic findings have been similar to adults, with fever and respiratory symptoms being prevalent, but fewer children seem to have developed severe pneumonia. Elevated inflammatory markers were less common in children, and lymphocytopenia seemed rare. Newborn infants have developed symptomatic COVID-19, but evidence of vertical intrauterine transmission was scarce. Suggested treatment included providing oxygen, inhalations, nutritional support and maintaining fluids and electrolyte balances. CONCLUSIONS The coronavirus disease 2019 has occurred in children, but they seemed to have a milder disease course and better prognosis than adults. Deaths were extremely rare.

The novel coronavirus disease 2019 (COVID-19) is caused by infection from the newly emerged, highly contagious coronavirus SARS-CoV-2. The aim of this study was to analyse the association between plasma glucose levels and clinic outcomes in COVID-19 patients with type 2 diabetes (T2D). The study is a retrospective longitudinal, multi-centre study from a cohort of 7,337 COVID-19 cases enrolled among 19 hospitals. Results show that patients with pre-existing T2D received significantly more intensive integrated treatments to manage their symptoms of COVID-19 than the non-diabetic subjects. Furthermore, findings indicate that well-controlled blood glucose was associated with a markedly improved outcome of patients with COVID-19 and pre-existing T2D. Authors conclude that T2D is an important risk factor for COVID-19 progression and adverse endpoints, and well-controlled blood glucose is associated with a significant reduction in the composite adverse outcomes and death.
Abstract
Type 2 diabetes (T2D) is a major comorbidity of COVID-19. However, the impact of blood glucose (BG) control on the degree of required medical interventions and on mortality in patients with COVID-19 and T2D remains uncertain. Thus, we performed a retrospective, multi-centered study of 7,337 cases of COVID-19 in Hubei Province, China, among which 952 had pre-existing T2D. We found that subjects with T2D required more medical interventions and had a significantly higher mortality (7.8% versus 2.7%; adjusted hazard ratio [HR], 1.49) and multiple organ injury than the non-diabetic individuals. Further, we found that well-controlled BG (glycemic variability within 3.9 to 10.0 mmol/L) was associated with markedly lower mortality compared to individuals with poorly controlled BG (upper limit of glycemic variability exceeding 10.0 mmol/L) (adjusted HR, 0.14) during hospitalization. These findings provide clinical evidence correlating improved glycemic control with better outcomes in patients with COVID-19 and pre-existing T2D.

Modifiable (behavioural) risk factors such as sedentary lifestyle and low sleep efficiency, are associated with increased mortality risk and disease progression in individuals with cardiovascular disease. The main aim of this study was to evaluate changes in objectively measured lifestyle and health data derived from wearable devices. This study was part of an international, multicenter randomized controlled trial, the Do Cardiac Health Advanced New Generation Ecosystem 2 study. Only the participants (n=70) randomised to the intervention group were analysed. The participants received the devices to monitor their lifestyle and health parameters. Results indicate significant changes over time in the number of steps and activity level. No significant improvement over time was observed in other outcome measures (i.e., blood pressure, weight, and sleep efficiency). Secondary analysis showed demographic (gender, nationality, marital status), clinical (co-morbidities, heart failure), and psychological (anxiety, depression) profiles that were associated with lifestyle measures. Authors conclude that a personalised approach might be the way forward in order to improve health outcomes in the future.
Abstract
The importance of modifying lifestyle factors in order to improve prognosis in cardiac patients is well-known. Current study aims to evaluate the effects of a lifestyle intervention on changes in lifestyle- and health data derived from wearable devices. Cardiac patients from Spain (n = 34) and The Netherlands (n = 36) were included in the current analysis. Data were collected for 210 days, using the Fitbit activity tracker, Beddit sleep tracker, Moves app (GPS tracker), and the Careportal home monitoring system. Locally Weighted Error Sum of Squares regression assessed trajectories of outcome variables. Linear Mixed Effects regression analysis was used to find relevant predictors of improvement deterioration of outcome measures. Analysis showed that Number of Steps and Activity Level significantly changed over time (F = 58.21, p < 0.001; F = 6.33, p = 0.01). No significant changes were observed on blood pressure, weight, and sleep efficiency. Secondary analysis revealed that being male was associated with higher activity levels (F = 12.53, p < 0.001) and higher number of steps (F = 8.44, p < 0.01). Secondary analysis revealed demographic (gender, nationality, marital status), clinical (co-morbidities, heart failure), and psychological (anxiety, depression) profiles that were associated with lifestyle measures. In conclusion results showed that physical activity increased over time and that certain subgroups of patients were more likely to have a better lifestyle behaviors based on their demographic, clinical, and psychological profile. This advocates a personalized approach in future studies in order to change lifestyle in cardiac patients.

Plain language summary
Depression and obesity are significant global health concerns. Depression can significantly impact physical health and reduced immune function. The aim of this study was to examine the potential benefits of a novel group psychological intervention program. The study is a preliminary quasi-experimental (single-arm) before-after pilot trial of a newly developed group-based psychological intervention program for people with depression and comorbid obesity. The program consisted of 10 two-hour group sessions held weekly. A total of 24 participants were recruited to the program across two pilot groups. Results indicate that there was a significant reduction in participants’ depression and anxiety scores by program-end. Some evidence also shows improvements in weight-related negative cognitions. Authors conclude that the group therapy program therefore has considerable potential to be effective in helping people enjoy better mental health and improve health outcomes.
Abstract
BACKGROUND Depression and obesity are significant global health concerns that commonly occur together. An integrated group cognitive behavioural therapy program was therefore developed to simultaneously address comorbid depression and obesity. METHODS Twenty-four participants (63% women, mean age 46 years) who screened positively for depression with a body mass index ≥25 were recruited from a self-referred general population sample. The group therapy program (10 two-hour weekly sessions) was examined in a single-arm, before-after pilot trial, conducted in a behavioural health clinic in Adelaide, Australia. Primary outcomes included survey and assessment-based analyses of depression, anxiety, body image, self-esteem, and weight (kg), assessed at four time-points: baseline, post-intervention, three-months and 12-months post program. Eighteen participants (75%) completed the program and all assessments. RESULTS Significant improvements in depression, anxiety, self-esteem and body shape concern scores, several quality of life domains, eating behaviours and total physical activity (among others) - but not weight - were observed over the course of the trial. CONCLUSIONS Results from this pilot trial suggest that combining interventions for depression and obesity may be useful. Further development of the program, particularly regarding the potential for physical health benefits, and a randomised controlled trial, are warranted. TRIAL REGISTRATION Trial registration: ANZCTR, ACTRN12617001079336, 13 July 2017. Retrospectively registered after date of the first consent (6 July 2017), but before the date of the first intervention session (20 July 2017).

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
Evidence suggests that the Mediterranean diet (MD) may help prevent cardiovascular disease (CVD). However, this could be influenced by an individual’s gut microbiome, highlighting a need for personalised nutrition practices. This randomised crossover control trial aimed to evaluate an 8-week personalised MD intervention in 82 overweight and obese subjects, who were at high risk of cardiovascular disease. The results showed that a personalised MD lowered cholesterol, regardless of the amount of energy consumed and the amount of exercise performed and relied upon adherence to the MD. Gut microbiome composition was altered by a MD and although markers for diabetes were not improved overall, there was an improvement in prediabetes in individuals with higher levels of Bacteroides species and lower levels of Prevotella species. It was concluded that a MD may reduce cholesterol and alter the gut microbiome to benefit cardiovascular health. Health professionals could use this study to switch patients to a MD whilst maintaining their energy intake to reduce cardiovascular risk. In order to see maximum benefit, it would be recommended to take a personalised approach and analyse an individual’s gut microbiome in order to tailor recommendations.
Abstract
OBJECTIVES This study aimed to explore the effects of an isocaloric Mediterranean diet (MD) intervention on metabolic health, gut microbiome and systemic metabolome in subjects with lifestyle risk factors for metabolic disease. DESIGN Eighty-two healthy overweight and obese subjects with a habitually low intake of fruit and vegetables and a sedentary lifestyle participated in a parallel 8-week randomised controlled trial. Forty-three participants consumed an MD tailored to their habitual energy intakes (MedD), and 39 maintained their regular diets (ConD). Dietary adherence, metabolic parameters, gut microbiome and systemic metabolome were monitored over the study period. RESULTS Increased MD adherence in the MedD group successfully reprogrammed subjects' intake of fibre and animal proteins. Compliance was confirmed by lowered levels of carnitine in plasma and urine. Significant reductions in plasma cholesterol (primary outcome) and faecal bile acids occurred in the MedD compared with the ConD group. Shotgun metagenomics showed gut microbiome changes that reflected individual MD adherence and increase in gene richness in participants who reduced systemic inflammation over the intervention. The MD intervention led to increased levels of the fibre-degrading and of genes for microbial carbohydrate degradation linked to butyrate metabolism. The dietary changes in the MedD group led to increased urinary urolithins, faecal bile acid degradation and insulin sensitivity that co-varied with specific microbial taxa. CONCLUSION Switching subjects to an MD while maintaining their energy intake reduced their blood cholesterol and caused multiple changes in their microbiome and metabolome that are relevant in future strategies for the improvement of metabolic health.

Plain language summary
Tomatoes are a rich source of lycopene, a compound believed to have many health benefits. Researchers in Japan conducted a randomised, double-blind, placebo-controlled trial to investigate the effects of eating a type of tomato bred to be high in lycopene on 74 healthy volunteers with raised cholesterol levels. Participants were given 50g per day of either semi-dried high-lycopene tomato or lycopene-free tomato. Those eating the high-lycopene tomatoes significantly reduced their levels of LDL cholesterol over 12 weeks. The researchers concluded that their findings support the health benefits of eating tomatoes rich in lycopene.
Abstract
undefined: Tomato ( ) is a rich source of lycopene, a carotenoid that confers various positive biological effects such as improved lipid metabolism. Here, we conducted a randomized, double-blind, placebo-controlled, parallel-group comparative study to investigate the effects of regular and continuous intake of a new high-lycopene tomato, a variety named PR-7, for 12 weeks, based on 74 healthy Japanese subjects with low-density lipoprotein cholesterol (LDL-C) levels ≥120 to <160 mg/dL. The subjects were randomly assigned to either the high-lycopene tomato or placebo (lycopene-free tomato) group. Each subject in the high-lycopene group ingested 50 g of semidried PR-7 (lycopene, 22.0-27.8 mg/day) each day for 12 weeks, while subjects in the placebo group ingested placebo semidried tomato. Medical interviews were conducted, vital signs were monitored, body composition was determined, and blood and saliva samples were taken at weeks 0 (baseline), 4, 8, and 12. The primary outcome assessed was LDL-C. The intake of high-lycopene tomato increased lycopene levels in this group compared to levels in the placebo group ( < 0.001). In addition, high-lycopene tomato intake improved LDL-C ( = 0.027). The intake of high-lycopene tomato, PR-7, reduced LDL-C and was confirmed to be safe.

Plain language summary
The incidence of type 1 diabetes and cardiovascular disease, the major vascular complication of diabetes, have been increasing wordwide. The aim of the study is to identify the associations of dietary fibre with glycaemic control. The study is a cross-sectional longitudinal study which enrolled 1257 individuals in the cross-sectional analysis and a total of 990 participants were included in the longitudinal analysis. The participants had no known history of coronary heart disease. Results indicate an inverse association between total fibre intake and the average blood glucose levels for the last two to three months in both diabetic and nondiabetic participants. Authors conclude that their study provides some evidence on the role dietary fibre intake plays on glycaemic control, which is important in the management of type 1 diabetes in patients at high risk of cardiovascular disease.
Abstract
BACKGROUND Dietary fiber has been recommended for glucose control, and typically low intakes are observed in the general population. The role of fiber in glycemic control in reported literature is inconsistent and few reports are available in populations with type 1 diabetes (T1D). METHODS Using data from the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study [n = 1257; T1D: n = 568; non-diabetic controls: n = 689] collected between March 2000 and April 2002, we examined cross-sectional (baseline) and longitudinal (six-year follow-up in 2006-2008) associations of dietary fiber and HbA1c. Participants completed a validated food frequency questionnaire, and a physical examination and fasting biochemical analyses (12 h fast) at baseline visit and at the year 6 visit. We used a linear regression model stratified by diabetes status, and adjusted for age, sex and total calories, and diabetes duration in the T1D group. We also examined correlations of dietary fiber with HbA1c. RESULTS Baseline dietary fiber intake and serum HbA1c in the T1D group were 16 g [median (IQ): 11-22 g) and 7.9 ± 1.3% mean (SD), respectively, and in the non-diabetic controls were 15 g [median (IQ): 11-21 g) and 5.4 ± 0.4%, respectively. Pearson partial correlation coefficients revealed a significant but weak inverse association of total dietary fiber with HbA1c when adjusted for age, sex, diabetes status and total calories (r = - 0.07, p = 0.01). In the adjusted linear regression model at baseline, total dietary fiber revealed a significant inverse association with HbA1c in the T1D group [β ± SE = - 0.32 ± 0.15, p = 0.034], as well as in the non-diabetic controls [- 0.10 ± 0.04, p = 0.009]. However, these results were attenuated after adjustment for dietary carbohydrates, fats and proteins, or for cholesterol and triglycerides. No such significance was observed at the year 6 follow-up, and with the HbA1c changes over 6 years. CONCLUSION Thus, at observed levels of intake, total dietary fiber reveals modest inverse associations with poor glycemic control. Future studies must further investigate the role of overall dietary quality adjusting for fiber-rich foods in T1D management.

Plain language summary
Vegetable sprouts are naturally rich in nutrients and other beneficial compounds. The sprouts of cruciferous vegetables, such as broccoli, kale, radish and pak choi, stand out due to their high contents of glucosinolates and phenolic compounds. The aim of this review was to compile and update the available knowledge on the production, nutritional composition, and health benefits of cruciferous sprouts. A number of studies have found that compounds found in cruciferous sprouts have anti-cancer, anti-inflammatory, and antioxidant capacities. Consumption of cruciferous sprouts contributes to healthy glucose, insulin and fat levels in the blood, and may be beneficial for the treatment of some metabolic disorders, such as type 2 diabetes. There is evidence that compounds in cruciferous sprouts are a useful tool for enhancing phase II enzymes in the liver, and benefit levels of interleukine-6, C-reactive protein, and tumour necrosis factor-α, and inhibition of NF-κB, among others. The active compounds in these sprouts have an influence on several cardiovascular processes, potentially reducing the risk of several diseases. The lack of consistency between studies with regard to sampling schedules, doses, sample size, etc. means that it is not possible at this time to state the effective dose of sprouts or their active compounds needed in order to achieve health benefits. Further research is needed in this area.
Abstract
Edible sprouts with germinating seeds of a few days of age are naturally rich in nutrients and other bioactive compounds. Among them, the cruciferous (Brassicaceae) sprouts stand out due to their high contents of glucosinolates (GLSs) and phenolic compounds. In order to obtain sprouts enriched in these phytochemicals, elicitation is being increasing used as a sustainable practice. Besides, the evidence regarding the bioavailability and the biological activity of these compounds after their dietary intake has also attracted growing interest in recent years, supporting the intake of the natural food instead of enriched ingredients or extracts. Also, there is a growing interest regarding their uses, consumption, and applications for health and wellbeing, in different industrial sectors. In this context, the present review aims to compile and update the available knowledge on the fundamental aspects of production, enrichment in composition, and the benefits upon consumption of diverse edible cruciferous sprouts, which are sources of phenolic compounds and glucosinolates, as well as the evidence on their biological actions in diverse pathophysiological situations and the molecular pathways involved.

Plain language summary
Probiotics have been shown to reduce total cholesterol (TC) and low-density lipoprotein (LDL-C – often called ‘bad’ cholesterol) in people with moderately raised cholesterol levels. A specific strain of probiotic called Bifidobacterium longum BB536, may decrease TC and LDL-C by reducing the reabsorption of cholesterol from the intestine, and, combined with other natural supplements, may be useful to manage high cholesterol in people at low risk of heart disease. This study was conducted to evaluate the effect of a nutraceutical (Lactoflorene Colesterolo®), containing Bifidobacterium longum BB536 (1bn CFUs) combined with red yeast rice (RYR) extract (10 mg/day monacolin K), niacin (16mg) and coenzyme Q10 (20mg) on levels of cholesterol and fats in the blood. This was a 12-week randomised, parallel, double-blind, placebo-controlled study, in which 33 adults at low risk of heart disease were given either the Bifidobacterium combination, or a placebo. Treatment with the Bifidobacterium combination significantly reduced total cholesterol by 16.7%, LDL-C by 25.7%, non-HDL-C by 24% and apolipoprotein-B by 17%. Triglycerides, HDL-C, apolipoprotein AI, lipoprotein (a) and proprotein convertase subtilisin/kexin type 9 (PCSK9) were unchanged. Markers of cholesterol synthesis and absorption suggested that a reduction in the synthesis of cholesterol had occurred without increased absorption of cholesterol. No adverse effects were reported in the study and the compliance rate was high at 97%. The use of nutraceuticals in the prevention of cardiovascular disease, as well as in other areas related to chronic diseases like cancer, is currently expanding.
Abstract
BACKGROUND Probiotics incorporated into dairy products have been shown to reduce total (TC) and LDL cholesterolemia (LDL-C) in subjects with moderate hypercholesterolemia. More specifically, probiotics with high biliary salt hydrolase activity, e.g. Bifidobacterium longum BB536, may decrease TC and LDL-C by lowering intestinal cholesterol reabsorption and, combined with other nutraceuticals, may be useful to manage hypercholesterolemia in subjects with low cardiovascular (CV) risk. This study was conducted to evaluate the efficacy and safety of a nutraceutical combination containing Bifidobacterium longum BB536, red yeast rice (RYR) extract (10 mg/day monacolin K), niacin, coenzyme Q10 (Lactoflorene Colesterolo®). The end-points were changes of lipid CV risk markers (LDL-C, TC, non-HDL-cholesterol (HDL-C), triglycerides (TG), apolipoprotein B (ApoB), HDL-C, apolipoprotein AI (ApoAI), lipoprotein(a) (Lp(a), proprotein convertase subtilisin/kexin type 9 (PCSK9)), and of markers of cholesterol synthesis/absorption. METHODS A 12-week randomized, parallel, double-blind, placebo-controlled study. Thirty-three subjects (18-70 years) in primary CV prevention and low CV risk (SCORE 0-1% in 24 and 2-4% in 9 subjects; LDL-C: 130-200 mg/dL) were randomly allocated to either nutraceutical (N = 16) or placebo (N = 17). RESULTS Twelve-week treatment with the nutraceutical combination, compared to placebo, significantly reduced TC (- 16.7%), LDL-C (- 25.7%), non-HDL-C (- 24%) (all p < 0.0001), apoB (- 17%, p = 0.003). TG, HDL-C, apoAI, Lp(a), PCSK9 were unchanged. Lathosterol:TC ratio was significantly reduced by the nutraceutical combination, while campesterol:TC ratio and sitosterol:TC ratio did not change, suggesting reduction of synthesis without increased absorption of cholesterol. No adverse effects and a 97% compliance were observed. CONCLUSIONS A 12-week treatment with a nutraceutical combination containing the probiotic Bifidobacterium longum BB536 and RYR extract significantly improved the atherogenic lipid profile and was well tolerated by low CV risk subjects.
