Several countries have reported higher death rates and more severe cases of covid-19 amongst individuals with chronic diseases such as type 2 diabetes. This review of 100 papers aimed to investigate the interconnecting factors which may contribute to poorer prognosis in individuals with covid-19 and type 2 diabetes. Although the evidence suggests that patients with type 2 diabetes have poorer outcomes after contracting covid-19, they are not more susceptible to infection. The paper reported that mechanisms which may increase severity in type 2 diabetics are abnormal immune function, increased susceptibility to inflammation, the increased adherence of the virus to target cells and reduced ability to fight infection. It is important to manage blood sugars when suffering from covid-19. The paper reviewed the use of several medications such as metformin, dipeptidyl peptidase-4 inhibitors (DPP4), glucagon-like peptide-1 agonists and insulin in the context of individuals suffering from covid-19, with insulin being the treatment of choice in the acutely ill patient. Current treatments of covid-19 were also reviewed such as chloroquine and hydroxychloroquine, Lopinavir-ritonavir, IL-6 receptor agonists, type 1 interferon and remdesivir. It was concluded that clinicians should be aware of the risks in patients with type 2 diabetes and covid-19. However as new data is made available, the chronic and long-term implications will become clearer. This study could be used by health care professionals to ensure that patients with type 2 diabetes do everything they can to avoid covid-19 infection and that if contracted these patients are closely monitored for severe disease.
Abstract
Coronavirus disease 2019 (COVID-19) is a global pandemic that is caused by a novel coronavirus, severe acute respiratory syndrome coronavirus-2. Data from several countries have shown higher morbidity and mortality among individuals with chronic metabolic diseases, such as diabetes mellitus. In this review, we explore the contributing factors for poorer prognosis in these individuals. As a significant proportion of patients with COVID-19 also have diabetes mellitus, this adds another layer of complexity to their management. We explore potential interactions between antidiabetic medications and renin-angiotensin-aldosterone system inhibitors with COVID-19. Suggested recommendations for the use of antidiabetic medications for COVID-19 patients with diabetes mellitus are provided. We also review pertinent clinical considerations in the management of diabetic ketoacidosis in COVID-19 patients. In addition, we aim to increase clinicians' awareness of the metabolic effects of promising drug therapies for COVID-19. Finally, we highlight the importance of timely vaccinations for patients with diabetes mellitus.

Plain language summary
The body has many uses for the energy that is consumed in the diet, one of these is for the generation of heat. Brown adipose tissue (BAT), which is stored in the lower neck, collarbone, abdomen and along the spine, is a special type of fat that is activated when the body is cold and serves to generate heat. The activity of this fat is of benefit to humans, as it reduces weight gain, improves blood sugar balance, and helps reduce blood lipid levels, reducing the risk for heart disease and type 2 diabetes. This systematic review of 24 publications aimed to determine whether nutrition and/or diet affects the activity of BAT. The results showed that there was no change in BAT activity following a high calorie carbohydrate rich meal, a standard meal and during overfeeding. Supplementation of L-Arginine, which is a supplement that helps the body build muscle, also had no effect on BAT activity. It was concluded that BAT activity was not affected by nutrition or diet. This study could be used by healthcare professionals to understand that the effect of diet on risk for heart disease and type 2 diabetes may not involve the modification of BAT.
Abstract
BACKGROUND Brown adipose tissue (BAT) provides a minor contribution to diet-induced thermogenesis (DIT)-the metabolic response to food consumption. Increased BAT activity is generally considered beneficial for mammalian metabolism and has been associated with favorable health outcomes. The aim of the current systematic review was to explore whether nutritional factors and/or diet affect human BAT activity. METHODS We searched PubMed Central, Embase and Cochrane Library (trials) to conduct this systematic review (PROSPERO protocol: CRD42018082323). RESULTS We included 24 eligible papers that studied a total of 2785 participants. We found no mean differences in standardized uptake value of BAT following a single meal or after 6 weeks of L-Arginine supplementation. Resting energy expenditure (REE), however, was increased following a single meal and after supplementation of capsinoid and catechin when compared to a control condition (Z = 2.41, p = 0.02; mean difference = 102.47 (95% CI = 19.28-185.67)). CONCLUSIONS Human BAT activity was not significantly affected by nutrition/diet. Moreover, REE was only increased in response to a single meal, but it is unlikely that this was due to increased BAT activity. BAT activity assessments in response to the chronic effect of food should be considered along with other factors such as body composition and/or environmental temperature.

The impact of environmental, lifestyle and nutritional factors on unexplained male fertility has long been acknowledged. Yet, little research had been dedicated to the topic, despite declining semen quality having become a worldwide phenomena. Available studies have yielded limited, and at times conflicting, evidence. Hence this literature review sought to capture the current knowledge around unexplained male infertility and environmental, lifestyle, diet and nutrients factors. Summarized is the evidence from 69 studies, including population observations and clinical trials. The collected outcomes showed that a Western-type diet, rich in red and processed meats, refined grains, high-energy drinks and sweets, trans and saturated fats was associated with poor semen quality. Whereby higher intakes of fruits and vegetables, whole grains, omega-3 and poultry showed beneficial effects. However, as only selected groups were examined, more research is needed to project such findings onto the wider population. The reviewed evidence also included alcohol consumption, which showed high alcohol intake closely correlated to declining sperm concentrations. Whilst the verdict on caffeine consumption and the impact on sperm quality was inconclusive. In addition, several interventional studies evaluated the effect of dietary supplementation on various parameters of semen, where coenzyme Q10, L-carnitine, vitamin E, antioxidants, combined nutrient formulations and herbal blends all had positive outcomes. The review on zinc and folic acid supplementation yielded mixed results. This brief recap of the current evidence on environmental, lifestyle and nutritional influences on male infertility summarises the dietary foundations for the support of unexplained male infertility.
Abstract
BACKGROUND AND AIMS Male unexplained infertility has long been suspected to result from environmental, lifestyle and nutritional factors. However, the literature on the subject is still scarce, and clinical studies providing robust evidence are even scarcer. In addition, some similar studies come to different conclusions. Dietary pattern can influence spermatogenesis by its content of fatty acids and antioxidants. Yet, in an age of industrialized mass food production, human bodies become more exposed to the ingestion of xenobiotics, as well as chemicals used for production, preservation, transportation and taste enhancement of foods. We attempted in this paper to collect the available evidence to date on the effect of nutritional components on male fertility. MATERIAL AND METHODS A systematic search of the relevant literature published in PubMed, ScienceDirect and Cochrane Central Register of Controlled Trials Database was conducted. Literature was evaluated according to the Newcastle-Ottawa- Scale. RESULTS Epidemiological observations are concordant in demonstrating an association of low-quality sperm parameters with higher intake of red meat, processed and organ meat and fullfat dairy. On the contrary, better semen parameters were observed in subjects consuming a healthy diet, rich in fruit, vegetables, whole grains and fish. Evidences of the negative impact on male fertility of by-products of water disinfection, accumulation in food chain of persistent organochlorine pollutants, pesticides, phthalates from food and water containers and hormones used in breeding cattle have been reported. Clinical trials of the effects of micronutrients on semen parameters and outcomes of assisted fertilization are encouraging, although optimal modality of treatment should be established. CONCLUSIONS Although quality of evidence should be ameliorated, it emerges that environmental factors can influence male fertility. Some nutrients may enhance fertility whereas others will worsen it. With diagnostic analysis on a molecular or even sub-molecular level, new interactions with micronutrients or molecular components of our daily ingested foods and leisure drugs may lead to a better understanding of so far suspected but as yet unexplained effects on male spermatogenesis and fertility.

Plain language summary
Following Covid-19 infection, sufferers have reported various residual symptoms, which have been likened to those experienced by chronic fatigue sufferers and those with Gulf War syndrome. This review paper aimed to assess whether the body has a similar immune response to these diseases during Covid-19, and if so, what therapies could be used. It also reviewed any diet and lifestyle factors that may be affecting the immune response. The paper stated that Covid-19 infection is associated with inflammation, which can damage immune cells and inflammation prior to Covid-19 infection may contribute to severity of the infection. Prior research in seemingly healthy individuals indicates that environment, diet, and lifestyle factors can all contribute to differing “immune identities” and eliminating immune cells which carry the imprint of memories should be a therapy focus in Covid-19 patients. Fasting, diets low in refined sugars and high in omega-3 and plant chemicals were discussed as ways for the body to clear out immune cells. It was concluded that personalising therapy strategies based on an individual’s immune identity to reduce inflammation could ultimately support the immune system. This paper could be used by healthcare professionals to understand the importance of diet and lifestyle changes to reduce inflammation and support the immune system.
Abstract
With the COVID-19 pandemic still affecting communities all over the world and "Long Haul" chronic health issues emerging, it is time for us to look back at past multi-symptom health conditions that required a different approach to their treatment, beyond just managing symptoms. It is important for us to consider how to apply what we have learned about immune rejuvenation and its impact on conditions associated with chronic immune dysfunction. We know more than we ever have before about how to reduce chronic inflammation at its source through the support of selective immune cell autophagy/mitophagy and improved immune cell mitochondrial activity, followed by remodeling of the immune epigenome, and-ultimately-a reset of immune function.

Plain language summary
In individuals at high risk of type 2 diabetes, lifestyle interventions rather than medication have been more successful in preventing development of the disease, however the benefits of lifestyle strategies diminishes over time due to possible adherence issues. Prolonged lifestyle changes may be affected by lack of family support, but research on family support during lifestyle changes in individuals prior to diabetes is lacking. This parallel randomised control trial of 122 patients with prediabetes and 101 of their family members aimed to assess the impact of family supported diet and exercise changes compared to self-motivation on individuals with prediabetes. At 6 months, body measurements and markers of prediabetes improved in both groups. Lipids were significantly improved in the group with family support compared to having no support. At 12 months there were a high number of dropouts due to lack of patient interest. Benefits shown at 6 months in both groups were only maintained or improved upon with family support and the lipid profile of the individual intervention group actually worsened in comparison to when participants entered the trial. After 12 months the incidence rate of type 2 diabetes was similar in both groups. Individuals with prediabetes who had family support whilst undergoing a diet and exercise regime were more successful at maintaining improvements of factors contributing to diabetes, compared to individuals without support. However this did not affect the occurrence of type 2 diabetes. Clinicians could use this paper to communicate the importance of family support during lifestyle changes in patients at high risk of developing type 2 diabetes, although close monitoring may be required to ensure compliance.
Abstract
BACKGROUND Lifestyle changes can reduce the risk of T2D; however, no study has evaluated the effect of a lifestyle intervention involving patients´ family. The aim of this study was to compare the impact of an interdisciplinary family (FI) Vs individual intervention (II) on glucose metabolism, insulin resistance (IR), pancreatic β-cell function and cardiovascular risk markers in patients with prediabetes, as well as to measure the impact on their families' metabolic risk. METHODS Randomized Clinical Trial (RCT) to compare the impact of FI and II on IR and pancreatic β-cell function in subjects with prediabetes. There were 122 subjects with prediabetes (and 101 family members) randomized to FI or II. Data were collected in 2015-2016 and analyzed in 2017-2018. FI group had the support of their family members, who also received personalized diet and exercise recommendations; patients and their family members attended monthly a lifestyle enhancement program. II group received personalized diet and exercise recommendations. The follow-up was for 12 months. Glucose, IR, pancreatic β-cell function and secondary outcomes (body composition and lipid profile) were assessed at baseline, 6 and 12 months. RESULTS FI group improved area under the glucose curve (AUC) (from 18,597 ± 2611 to 17,237 ± 2792, p = 0.004) and the Matsuda index (from 3.5 ± 2.3 to 4.7 ± 3.5, p = 0.05) at 12 months. II group improved Disposition Index (from 1.5 ± 0.4 to 1.9 ± 0.73, p < .0001) at 12 months. The improvements achieved in weight and lipids at 6 months, were lost in II group at 12 moths, whereas in FI persisted. Adherence up to 12 months was not different between the study groups (FI 56% Vs II 60%). CONCLUSIONS FI intervention was more effective by improving glucose AUC, insulin sensitivity and lipid profile, besides that, metabolic risk in family members of the FI group was maintained, while the risk of II group was increased. TRIAL REGISTRATION This study was retrospectively registered at clinicaltrials.gov on December 15, 2015 (NTC026365646).

Plain language summary
Non-alcoholic fatty liver disease covers a range of conditions from excess fat in the liver through inflammation and fibrosis, to advanced fibrosis, and cirrhosis. The Enhanced Liver Fibrosis (ELF) score is emerging as a promising blood biomarker for fibrosis. The aim of this study was to examine whether a community weight loss programme reduces ELF score over 12 months compared with a weight-loss intervention which is less effective. This study is a secondary analysis of a published randomised controlled trial. Participants (n=73) were equally randomised to a community weight loss programme (WeightWatchers) or usual care. Results indicate that there was no evidence of an effect of a community weight loss programme on changes in the ELF score and no association between weight loss and the ELF score in people who had, on average, an ELF score compatible with moderate fibrosis. Authors conclude that using the ELF test to assess weight loss treatment efficacy in improving liver fibrosis may be of limited value, thus biopsy remains the gold-standard assessment for liver fibrosis.
Abstract
BACKGROUND Referral to weight loss programmes is the only effective treatment for non-alcoholic fatty liver disease (NAFLD). Clinicians should advise weight loss and screen for liver fibrosis using the Enhanced Liver Fibrosis (ELF) score. AIM: To examine if the ELF score changes with weight loss. DESIGN AND SETTING Randomised controlled trial (ISRCTN85485463) in UK primary care during 2007-2008. METHOD Adults with a BMI of 27-35 kg/m2 and ≥1 risk factor for obesity-related disease were randomised to attend a community weight loss programme (n = 45) or receive usual weight loss advice from a practice nurse (n = 28). Weight and the ELF score were measured at baseline and 1 year. Analysis of covariance examined mean changes in the ELF score between groups and its relationship with weight loss. RESULTS Mean (SD) BMI was 31.10 kg/m2 (2.55) with evidence of moderate levels of liver fibrosis at baseline (mean ELF score: 8.93 [0.99]). There was no evidence that the community weight loss programme reduced the ELF score compared with usual care (difference +0.13 points, 95% CI: -0.25 to 0.52) despite greater weight loss (difference: -2.66 kg, 95% CI: -5.02 to -0.30). Mean weight loss in the whole cohort was 7.8% (5.9). There was no evidence of an association between weight change and change in ELF; the coefficient for a 5% weight loss was -0.15 (95% CI: -0.30 to 0.0002). CONCLUSION We found no evidence that the ELF score changed meaningfully following moderate weight loss. Clinicians should not use the ELF score to measure improvements in NAFLD fibrosis following weight loss programmes.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is characterised by accumulation of fats in the liver and is particularly prevalent in postmenopausal women, due to a decrease in oestrogen, which leads to weight gain. Higher than normal resting heart rate has been shown to be a predictor of heart disease, however studies that look at the relationship between heart rate and NAFLD are lacking. This cross-sectional, observation study of 1315 postmenopausal women aimed to look at the relationship between resting heart rate and NAFLD. The results showed that the overall prevalence of NAFLD was increased with increased resting heart rate. It was concluded that resting heart rate was associated with NAFLD in postmenopausal women and it could be used as an additional predictor for risk of the disease. This study could be used by healthcare practitioners to understand the possible relationship between resting heart rate and the risk of developing NAFLD.
Abstract
Resting heart rate, a simple and useful indicator of autonomic function, and its imbalance has emerged as an independent predictor of cardio metabolic diseases. Nonalcoholic fatty liver disease (NAFLD) is increasingly being diagnosed worldwide and is strongly associated with the features of cardiometabolic diseases. This study aimed to examine the association between resting heart rate and NAFLD in postmenopausal women.The cross-sectional study included 1017 postmenopausal women aged ≥46 years, who attended a health examination program. Resting heart rate and NAFLD were measured in all subjects who underwent a medical examination. Resting heart rate quartiles were categorized as follows: Q1: 56 to 65, Q2: 66 to 71, Q3: 72 to 78, and Q4: 79 to 99 beats/min. The odds ratios and 95% confidence intervals for NAFLD were calculated after adjusting for confounding variables across resting heart rate quartiles using multiple logistic regression analysis.The prevalence of NAFLD increased with increasing resting heart rate quartiles: 28.2% for Q1, 31.5% for Q2, 33.4% for Q3, and 38.1% for Q4 (P < .001). Compared to the 1st quartile, the odds ratio (95% confidence intervals) of NAFLD in the 4th quartile of resting heart rates was 2.11 (1.17-3.42) after adjusting for age, body mass index, cigarette smoking, regular exercise, blood pressure, total cholesterol, triglyceride, aspartate aminotransferase, and alanine aminotransferase levels.Resting heart rate was positively associated with NAFLD in postmenopausal women, suggesting that it could be a useful additional measure to assess the risk for NAFLD in postmenopausal women.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is a condition linked to obesity and is characterised by high amounts of fat in the liver. This can lead to a high rate of mortality, but it can be improved by diet and exercise. It is unclear as to the best form of exercise for the improvement of NAFLD. This randomised control trial aimed to assess the effects of high-intensity interval exercise (HII) versus moderate-intensity exercise on liver fat content in 47 diabetic obese patients with NAFLD over 8 weeks. The results showed that regardless of exercise treatment, both improved measures of NAFLD and there were no differences between the two groups. Interestingly blood sugar control was also improved with both exercise treatments. It was concluded that both exercise regimes improved contributors to NAFLD, with no differences between the two treatments. This study would be useful to health professionals when recommending exercise to diabetic obese patients especially those with NAFLD, giving them the option of HII or MIC to improve their condition.
Abstract
BACKGROUND Some studies assessed the effect of aerobic exercise on diabetic obese patients with hepatic disease, while very limited studies compared high-intensity interval (HII) versus moderate-intensity continuous (MIC) on diabetic obese patients with non-alcoholic fatty liver disease (NAFLD). OBJECTIVES This study was designed to assess the effects of HII versus MIC on intrahepatic triglycerides (IHTG) and visceral lipids in diabetic obese patients with NAFLD. DESIGN Randomized controlled trial. METHODS Forty-seven diabetic obese individuals with NAFLD were enrolled in this study. The individuals were randomly divided into 16 in HII group, 15 in MIC group, and 16 in the controls. HII group received HII exercise, MIC group received 8-week MIC exercise while the control group did not receive any exercise intervention. IHTG and visceral lipids were assessed pre- and post-intervention. RESULTS Baseline and clinical characteristics showed nonsignificant difference among the 3 groups (P > .05). Both HII and MIC groups showed a significant reduction in hepatic fat and visceral lipids (P < .05), while the controls showed nonsignificant difference (P > .05) after completing the study intervention. Postintervention analysis showed nonsignificant changes between the HII and MIC groups (P > .05). CONCLUSIONS Exercise training wither HII or MIC aerobic exercise reduces IHGT and visceral lipids in diabetic obese patients with NAFLD. No differences were observed between the effects of both exercise programs on diabetic obese patients with NAFLD.

Plain language summary
Excess fat in the liver, known as non-alcoholic fatty liver disease (NAFLD), has been shown to increase the risk of chronic diseases such as type 2 diabetes. Standard treatment regimens consist of low-calorie (LC) diets and exercise, however these may be ineffective at reversing fat accumulation in the liver. A very low-calorie ketogenic diet (VLCKD) has been proposed as an alternative treatment for NAFLD. This randomised control pilot study of 39 individuals with obesity aimed to compare LC diet and VLCKD on fat accumulation and indicators for NAFLD for two months. The results showed greater weight loss, abdominal fat reduction, liver fat reduction and improvements in liver function with VLCKD compared to the LC diet. Cholesterol was significantly reduced by both diets. However liver stiffness remained unchanged. The authors concluded that VLCKD was more successful at reducing liver fat and abdominal fat accumulation than current standard therapy and has the potential to improve NAFLD. Health care professionals could use this study to improve liver and abdominal fat loss in patients with obesity to improve NAFLD, when standard therapy has been inadequate.
Abstract
Background: Currently the treatment of non-alcoholic fatty liver disease (NAFLD) is based on weight loss through lifestyle changes, such as exercise combined with calorie-restricted dieting. Objectives: To assess the effects of a commercially available weight loss program based on a very low-calorie ketogenic diet (VLCKD) on visceral adipose tissue (VAT) and liver fat content compared to a standard low-calorie (LC) diet. As a secondary aim, we evaluated the effect on liver stiffness measurements. Methods: Open, randomized controlled, prospective pilot study. Patients were randomized and treated either with an LC or a VLCKD and received orientation and encouragement to physical activity equally for both groups. VAT, liver fat fraction, and liver stiffness were measured at baseline and after 2 months of treatment using magnetic resonance imaging. Paired t-tests were used for comparison of continuous variables between visits and unpaired test between groups. Categorical variables were compared using the χ2-test. Pearson correlation was used to assess the association between VAT, anthropometric measures, and hepatic fat fraction. A significance level of the results was established at p < 0.05. Results: Thirty-nine patients (20 with VLCKD and 19 with LC) were evaluated at baseline and 2 months of intervention. Relative weight loss at 2 months was -9.59 ± 2.87% in the VLCKD group and -1.87 ± 2.4% in the LC group (p < 0.001). Mean reductions in VAT were -32.0 cm2 for VLCKD group and -12.58 cm2 for LC group (p < 0.05). Reductions in liver fat fraction were significantly more pronounced in the VLCKD group than in the LC group (4.77 vs. 0.79%; p < 0.005). Conclusion: Patients undergoing a VLCKD achieved superior weight loss, with significant VAT and liver fat fraction reductions when compared to the standard LC diet. The weight loss and rapid mobilization of liver fat demonstrated with VLCKD could serve as an effective alternative for the treatment of NAFLD. Clinical Trial Registration: ClinicalTrials.gov, identifier: NCT04322110.

Plain language summary
Non-alcoholic fatty liver disease (NAFLD) is common in people with obesity and is characterised by high amounts of fat stored in the liver. Diet and exercise are the standard treatments, however recent studies have indicated that the gut microbiota may have an important role. This randomised control trial of 140 patients with NAFLD, aimed to assess the effect of probiotics when added to standard therapy for 3 months. The results showed that although gut microbiota, some aspects of liver function, blood lipids and blood sugars were all improved in individuals on standard therapy, there were additional improvements in those on standard therapy plus probiotics. It was concluded that although standard therapy alone is adequate to improve NAFLD, probiotics plus standard therapy was superior to standard therapy alone and effective in treatment of NAFLD. This study could be used by health professionals to justify the addition of probiotics to standard therapy to further improve NAFLD outcomes.
Abstract
To investigate the effects of probiotics on liver function, glucose and lipids metabolism, and hepatic fatty deposition in patients with non-alcoholic fatty liver disease (NAFLD).Totally 140 NAFLD cases diagnosed in our hospital from March 2017 to March 2019 were randomly divided into the observation group and control group, 70 cases in each. The control group received the diet and exercise therapy, while the observation group received oral probiotics based on the control group, and the intervention in 2 groups lasted for 3 months. The indexes of liver function, glucose and lipids metabolism, NAFLD activity score (NAS), and conditions of fecal flora in 2 groups were compared before and after the treatment.Before the treatment, there were no significant differences on alanine aminotransferase (ALT), aspartate aminotransferase (AST), glutamine transferase (GGT), total bilirubin (TBIL), total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), insulin resistance index (HOMA-IR), NAFLD activity score (NAS), and conditions of fecal flora in 2 groups (P > .05). After the treatment, ALT, AST, GGT, TC, TG, HOMA-IR, NAS, and conditions of fecal flora in the observation group were better than those in the control group, and the observation group was better after treatment than before. All these above differences were statistically significant (P < .05).Probiotics can improve some liver functions, glucose and lipids metabolism, hepatic fatty deposition in patients with NAFLD, which will enhance the therapeutic effects of NAFLD.
