Plain language summary
Endometriosis is a common gynaecological disorder in reproductive-age women which leads to infertility and pain symptoms. Current pain management approaches involve medications and surgical treatments, but their side effects and risk of recurrence have led to the exploration of alternative options. The aim of this study was to clarify the potential effects of antioxidant vitamins supplementation on endometriosis. This study was a systematic review and meta-analysis of eleven studies, comprising a total of 589 patients. Results showed that antioxidant vitamins supplementation can effectively alleviate endometriosis-related pain and reduce inflammatory markers. Authors conclude that antioxidant vitamins supplementation can be considered as an alternative treatment either on its own or in combination with other methods for managing endometriosis-related pain. However, further research would help to provide a clearer understanding of the role of antioxidant vitamins supplementation in women with endometriosis.
Abstract
OBJECTIVE This study aimed to clarify the effect of antioxidant vitamins supplementation on endometriosis-related pain. METHODS A systematic search of PubMed, Web of Science, Cochrane Library, Scopus, and China National Knowledge Infrastructure (CNK) databases was conducted to identify relevant studies published in English and Chinese up to 16 March 2023. The search terms used were "endometriosis" OR "endometrioma" OR "endometrium" AND "antioxidant" OR "Vitamin C" OR "Vitamin E" OR "Vitamin D" OR "25-OHD" OR "25(OH)D" OR "25-hydroxyvitamin D". Eligible studies were randomized controlled trials (RCTs) that assessed pain scores using the Visual Analogue Scale (VAS). Mean differences or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the effect of antioxidant vitamins supplementation on endometriosis. The quality of the included studies was assessed using the Cochrane Risk of Bias Tool. The study was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. RESULTS A total of 13 RCTs involving 589 patients were included in this meta-analysis. We identified 11 studies that evaluated the effect of antioxidant vitamins supplementation on endometriosis-related pain. The results indicated that the supplementation of antioxidant vitamins can effectively alleviate endometriosis-related pain. Subgroup analysis showed that the supplementation of vitamin E (with or without vitamin C) had a positive effect on improving clinical pelvic pain in patients with chronic pelvic pain. Conversely, supplementation of vitamin D was associated with a reduction in pelvic pain in endometriosis patients, but the difference was not statistically significant compared to the placebo. Additionally, we observed changes in oxidative stress markers following vitamin supplementation. Plasma malondialdehyde (MDA) concentration decreased in patients with endometriosis after antioxidant vitamin supplementation, and the plasma MDA level was inversely correlated with the time and dose of vitamin E and C supplementation. Furthermore, the inflammatory markers in peritoneal fluid, including RANTES, interleukin-6, and monocyte chemoattractant protein-1, significantly decreased after antioxidant therapy. These findings suggest that antioxidant vitamins may alleviate pain in endometriosis patients by reducing inflammation. CONCLUSIONS The included studies support the potential role of antioxidant vitamins in the management of endometriosis. Supplementation with antioxidant vitamins effectively reduced the severity of dysmenorrhea, improved dyspareunia and pelvic pain, and enhanced quality of life in these patients. Therefore, antioxidant vitamin therapy could be considered as an alternative treatment method, either alone or in combination with other approaches, for endometriosis-related pain.

Menopause is a process that marks the end of the reproductive phase in women. Menopause means both that the ovaries stop producing eggs and that there is a sharp decline in the production of female hormones such as progesterone and oestrogen. The aim of this study was to discuss the benefits of exercise and dietary supplements during menopause. This study was a systematic review of ten articles. Results showed that: - both strength and aerobic training, as well as supplementation with calcium and vitamin D, increase bone mineral density. - combined strength and resistance training provide cardiovascular benefits, increase strength and muscle mass, and reduce the risk of sarcopenia. - physical exercise has a synergistic effect with some supplements, enhancing their effectiveness. Authors concluded that physical exercise can help combat many of the symptoms associated with menopause, providing benefits for a more vital menopause and a more vital old age.
Abstract
UNLABELLED With the aging of the population in developed countries, the number of middle-aged and older women is progressively increasing. During this stage, women suffer from a number of signs and symptoms that could be reduced or treated with physical exercise and dietary supplements. The main objective of this study was to analyse the benefits of exercise and dietary supplements during menopause. MATERIALS AND METHODS A systematic review of the scientific literature was performed according to the PRISMA 2020 protocol, searching the PubMed, Cochrane, Scopus, and WOS databases. Studies that met the inclusion criteria were assessed for methodological quality using the PEDro or AMSTAR-2 scales. RESULTS The searches yielded a total of 104 results, of which 10 were selected, with methodological quality ranging from fair to excellent. Each article examined the combination of a dietary supplement plan versus a placebo; plus an exercise routine versus another routine or a sedentary lifestyle. The results showed the benefits of combining a nutritional supplementation plan with an exercise routine during menopause. CONCLUSIONS The practice of weekly strength and endurance exercises, together with the consumption of certain dietary supplements, may be a good resource for coping with menopause in a healthy way.

Gestational Diabetes Mellitus (GDM) causes hyperglycaemia due to the deficit of insulin during pregnancy. Dietary and lifestyle management plays a vital role in maintaining glycaemic control in women with GDM to avoid health risks to the mother and baby. Therefore, this systematic review of fourteen randomised controlled trials evaluated the latest research advancements to identify effective nutritional strategies for managing hyperglycaemia in women with GDM. Among all the dietary strategies implemented in the included randomised controlled trials, probiotic supplementation and supplementation of probiotics and vitamin D were most effective in GDM. Further robust studies are required to evaluate the potential effectiveness of different nutritional strategies for managing GDM. Healthcare professionals can use the results of this systematic review to understand the latest evidence supporting nutritional strategy for women with GDM and the need for personalised support for managing hyperglycaemia in GDM.
Abstract
Gestational diabetes mellitus (GDM) is defined as hyperglycaemia first detected at any time during pregnancy with values lower than those determined by the WHO for diabetes diagnosis in adults. This pathology, with a worldwide prevalence of 13.4%, causes significant maternal and foetal risks. The first line of treatment consists of maintaining normo-glycaemia through an adequate diet and lifestyle changes. The aim is to synthesize the scientific evidence updating the nutritional recommendations for the effective management of GDM. A systematic review of the scientific literature was conducted following the PRISMA guidelines. Randomized clinical trials published within the last five years and providing information on nutritional recommendations to achieve an effective management of gestational diabetes were selected. The databases searched were PubMed, the WOS Core Collection, SCOPUS, and CINAHL, using the MeSH terms: "Diabetes, Gestational"; "Nutrition Assessment (nutrition*)"; "Diet"; "Eating"; and "Food"; with the Boolean operators "AND" and "OR". The PEDro scale (Physiotherapy Evidence Database) was used to assess the scientific quality of the studies, with a mean score of 8.9, indicating an average good scientific quality. Results: A total of 809 papers were collected, of which, after applying the inclusion and exclusion criteria, 14 randomized clinical trials were selected. Probiotic supplementation and co-supplementation with vitamin D have been found to be the most beneficial options for both mothers with GDM and neonates, but the most effective regimens are not known. Diets enriched with extra virgin olive oil (EVOO) and oat bran, as well as some recommendations focused on carbohydrates also seem effective, as well as diets designed for this group of women with GDM such as "CHOICE". Conclusions: Although there are numerous proposals that have been published in recent years focused on the diet of women with GDM in order to improve their results and those of their children, it is the supplementation with probiotics and the co-supplementation with vitamin D that is most agreed upon as beneficial; however, more research is needed into which protocols are most effective. Other proposals that could also be beneficial should be further studied.

Plain language summary
A deficiency of the thyroid hormone causes hypothyroidism (HT), whereas Autoimmune thyroiditis (AIT) is mainly an organ-specific autoimmune condition. Both HT and AIT are characterised by low-grade inflammation and inflammation in the thyroid gland. Dietary supplements may offer health benefits; however, previous research findings are inconclusive. This systematic review evaluated twenty-two controlled studies to understand the effectiveness of dietary supplements in reducing inflammation and oxidative stress and improving antioxidant and thyroid parameters in patients with HT or AIT. The efficacy of dietary supplements in improving thyroid health and reducing inflammation and oxidative stress was inconclusive due to the low quality of the included studies and the limited number of available studies. Selenium supplements might be beneficial in improving thyroid parameters and inflammation in patients with HT or AIT. Even though the therapeutic benefits of dietary supplements in treating thyroid disease were inconclusive, healthcare professionals can use them to address the common nutritional deficiencies in people with HT and AIT. Further, large, long-term, robust studies are required to assess the therapeutic utility of different dietary supplements in promoting the health of the thyroid gland.
Abstract
This systematic review aims to summarise the results of controlled trials on dietary supplements (DS) usage and inflammation, oxidative stress, antioxidant status, and thyroid parameter improvement in hypothyroidism (HT)/Hashimoto's thyroiditis (AIT) patients. The study protocol was registered with PROSPERO (no. CRD42022365149). A comprehensive search of the PubMed, Scopus, and Web of Science databases resulted in the identification of nineteen randomised controlled trials and three non-randomised studies for the review; three studies examined the effect of supplementation with vitamin D, twelve studies-with selenium, and seven studies-with other DS. Based on very limited evidence, the lack of influence of vitamin D supplementation on inflammatory parameters was found, while no studies have examined oxidative stress and antioxidant status parameters, and only one provided results for a single thyroid parameter after an intervention. Some evidence was found proving that selenium supplementation may decrease inflammation and improve thyroid parameters, but reaching a conclusion about its influence on oxidative stress and antioxidant status is not possible because of the insufficient number of studies. Additionally, due to examining other DS (e.g., multicomponent, Nigella sativa, and genistein) only in single studies, conclusions cannot be drawn. Further long-term, high-quality randomised controlled trials are necessary to better understand the influence of DS on inflammation, oxidative stress, and antioxidant status, as well as their potential to improve thyroid gland function in HT/AIT patients.

Plain language summary
Pre-eclampsia is hypertension that becomes present after 20 weeks of gestation combined with proteinuria or another maternal organ dysfunction. It causes problems in 3%–5% of all pregnancies and is estimated to cause at least 42 000 maternal deaths annually. Other than early delivery of the fetus, there is no cure for pre-eclampsia. There is little published information on diet and pre-eclampsia, so the aim of this review is to look at a number of dietary factors and to develop a set of nutritional guidelines to reduce the risk of pre-eclampsia in pregnancy. This dietary review looks at: obesity and gestational weight gain and the discussion of weight management interventions. Fibre, probiotics and prebiotics. Specific dietary patterns such as: diets high in fruit and vegetables, western dietary patterns, New Nordic diet, dietary approaches to stop hypertension (DASH diet) and the Mediterranean style diet. Evidence for vitamin D, calcium, selenium, folic acid, B12 and multivitamins/minerals is looked at. The authors have summarised their conclusions in a table. However, it is emphasised that dietary recommendations should be considered in combination with other preventive actions such as a screening policy or pharmacological agents that may be appropriate for high-risk groups.
Abstract
Pre-eclampsia affects 3%-5% of pregnant women worldwide and is associated with a range of adverse maternal and fetal outcomes, including maternal and/or fetal death. It particularly affects those with chronic hypertension, pregestational diabetes mellitus or a family history of pre-eclampsia. Other than early delivery of the fetus, there is no cure for pre-eclampsia. Since diet or dietary supplements may affect the risk, we have carried out an up-to-date, narrative literature review to assess the relationship between nutrition and pre-eclampsia. Several nutrients and dietary factors previously believed to be implicated in the risk of pre-eclampsia have now been shown to have no effect on risk; these include vitamins C and E, magnesium, salt, ω-3 long-chain polyunsaturated fatty acids (fish oils) and zinc. Body mass index is proportionally correlated with pre-eclampsia risk, therefore women should aim for a healthy pre-pregnancy body weight and avoid excessive gestational and interpregnancy weight gain. The association between the risk and progression of the pathophysiology of pre-eclampsia may explain the apparent benefit of dietary modifications resulting from increased consumption of fruits and vegetables (≥400 g/day), plant-based foods and vegetable oils and a limited intake of foods high in fat, sugar and salt. Consuming a high-fibre diet (25-30 g/day) may attenuate dyslipidaemia and reduce blood pressure and inflammation. Other key nutrients that may mitigate the risk include increased calcium intake, a daily multivitamin/mineral supplement and an adequate vitamin D status. For those with a low selenium intake (such as those living in Europe), fish/seafood intake could be increased to improve selenium intake or selenium could be supplemented in the recommended multivitamin/mineral supplement. Milk-based probiotics have also been found to be beneficial in pregnant women at risk. Our recommendations are summarised in a table of guidance for women at particular risk of developing pre-eclampsia.

Modifiable risk factors such as dyslipidemia, hyperglycemia, obesity, and hypertension are characteristics of cardio-metabolic disorder which may lead to diabetes or cardiovascular disease. Previous research has shown an association between vitamin D deficiency and cardio-metabolic disorders. Studies have also shown that vitamin D deficiency is prevalent in older people. Therefore, this systematic review and meta-analysis evaluated the beneficial effects of Vitamin D supplementation (VDS) on the cardio-metabolic profile in elderly people. Twelve studies are included in this systematic review and meta-analysis. VDS dosage ranged from 400 IU/day to 4000 IU/day generally in most of the included studies, and the duration of intervention ranged from two months to one year. This systematic review and meta-analysis showed an improvement in total cholesterol and triglycerides followed by VDS in elderly participants. The subgroup analysis revealed improved glycaemic indices in elderly people with glycaemic irregularities. Longer-term VDS intervention improved glycaemic control. Further robust studies are required as there is high heterogeneity in the form of the vitamin D, dosage, duration, route of administration and study design of the included studies in this research. However, healthcare professionals can use the results of this study to understand the therapeutic value of VDS in improving the cardio-metabolic health of elderly people.
Abstract
BACKGROUND There has been a longstanding interest in the potential effect of vitamin D in preventing cardiac-metabolic diseases. However, there are divergent results regarding the impact of vitamin D supplementation (VDS) on managing cardiac-metabolic outcomes in the elderly population. MATERIAL AND METHOD We systematically searched electronic databases; Web of Science, PubMed, Scopus, EMBASE, Cochrane, and ProQuest. We included all trials that evaluated the effect of VDS on cardiac-metabolic risk factors in the elderly population, which were published until 30 September 2021. The effects of VDS on cardiac-metabolic outcomes were assessed using standardized mean difference (SMD). A random-effect model was used to pool the SMD and 95% confidence interval (CI). RESULT The literature search identified 4409 studies, of which 12 trials met inclusion criteria. Results of random effect meta-analysis indicated a significant reduction in total cholesterol (TC) (SMD: - 0.14 mg/dl; 95% CI: - 0.25, - 0.02) and triglyceride (TG) (SMD: - 0.45 mg/dl; 95% CI: - 0.86, - 0.04) with VDS compared to the placebo. The subgroup analyses revealed that the reduction of TG in patients with diabetes and vitamin D deficiency was significant. Furthermore, short-term intervention (≤ 6 months) induced a significantly lower level of TG and insulin in comparison to longer duration (> 6 months). CONCLUSION The study suggests that VDS could improve insulin concentration and dyslipidemia in the elderly population. The systematic review was registered in Alborz university of medical sciences with 2060-01-03-1397 number and the Ethics council IR.ABZUMS.REC.1397.207 number.

Plain language summary
Vitamin D deficiency or insufficiency is a global epidemic, estimated to affect over one billion people worldwide, including children. The main function of vitamin D is the regulation of bone homeostasis but it is also involved in many other conditions such as cardiovascular disease, cancer, diabetes mellitus and autoimmune disorders. Recent studies show that sufficient levels of vitamin D seem to be necessary to maintain sleep and low vitamin D levels have been associated with shorter sleep duration. This systematic review is the first to assess the association between Vitamin D and sleep disorders in children, 14 articles were included. Vitamin D deficiency in children is associated with decreased sleep duration and poorer sleep efficiency, as well as with delayed bedtimes. Children with reduced vitamin D serum levels have a higher risk of excessive daytime sleepiness (EDS). Since vitamin D levels influence sleep duration, sleep duration can also influence vitamin D serum concentration suggesting a bidirectional relationship. Evidence is scarce and so further high-quality prospective cohort studies and well-designed randomized controlled trials (RCTs) are needed to determine the effect of vitamin D supplementation in children with sleep disorders.

Summary Review:
Introduction
Vitamin D levels have been associated with improved sleep in adults, but few studies have concentrated on the paediatric population. In order to identify if vitamin D plays a role regulating sleep in children and adolescents the paper reviewed studies, which looked at vitamin D in relation to sleep duration and quality of sleep. This included the following sleep disorders: obstructive sleep apnoea (OSA), restless leg syndrome (RLS) and insomnia.
Methods
- A broad systematic review following the PRISMA guidelines and using PubMed and Cochrane databases
- Search identified 748 papers. After exclusions for non-relevance, incorrect age group, or lack of data on sleep, 14 papers were included
- Due to the shortage of papers on this topic none of these papers were excluded, regardless of quality
- The participants in each study varied from 39 to 5289.
Results
The results highlighted:
- Plasma levels of vitamin D affect sleep duration and quality of sleep in children. Data taken from 5 studies
- Vitamin D cord blood levels were correlated to sleep in preschool children. Partly this was due to the mother’s vitamin D level during pregnancy affecting the level of vitamin D available to the foetus. Venous blood vitamin D level was linked to the sleep wake cycle of children. Data taken from 2 studies
- OSA was more likely to develop in children who had low vitamin D levels with a risk of 14.16% compared to a control group of 5.83% (1 study)
- Vitamin D supplementation was found to reduce neuron damage caused by hypoxia (1 study)
- An association exists between parental vitamin D insufficiency and their child’s vitamin D status (1 study). Data taken from 5 studies
- Vitamin D levels in specific diseases, such as coeliac disease (CD) showed a negative correlation with RLS
- For familial Mediterranean fever (FMF) vitamin D deficiency reduced sleep quality (36.5%). Data taken from 2 studies.
Conclusion
Notwithstanding the small number of studies, the review shows vitamin D deficiency, defined as <20 ng/mL, is associated with an increased risk for sleep disorders in children.
Clinical practice applications:
- Due to the role vitamin D plays in sleep in children, establishing vitamin D status may be useful for children presenting with sleep disturbances
- Adequate vitamin D levels during pregnancy are important to establish a vitamin D pool in the foetus
- Vitamin D supplementation is something to rule out in the case of OSA and associated hypoxia, metabolic dysfunction and systemic inflammation in children
- Due to the negative impact poor sleep has on the body, improving sleep quality at a young age could form an important part of preventative health care.
Considerations for future research:
- Additional studies are required to support the conclusion in this study
- Due to the low number of studies, any additional research should be of a high standard and include prospective cohort studies and randomised control trials.
Abstract
This review investigates the association between vitamin D and sleep disorders. Vitamin D is an essential nutrient known to play an important role in the growth and bone health of the human body, but it also appears to play a role in sleep. The goal of our review is to examine the association between vitamin D and sleep disorders in children and adolescents. We summarize the evidence about the role and the mechanism of action of vitamin D in children and adolescents with sleep disorders such as insomnia, obstructive sleep apnea (OSA), restless legs syndrome (RLS), and other sleep disorders. Systematic electronic database searches were conducted using Pubmed and Cochrane Library. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline was followed. The studies that met the established inclusion criteria were analyzed and compared. Results suggest a strict relationship between vitamin D deficiency in children and sleep disorders. There is evidence that vitamin D is implicated in the different neurochemical mechanisms involved in sleep regulation and mainly in the serotonergic and dopaminergic pathways. This might be responsible for the association of vitamin D deficiency and restless sleep, sleep hyperhidrosis, OSA, and RLS.

Plain language summary
Diabetes Mellitus (DM) affects more than 463 million people worldwide. Similarly, the number of deaths related to Alzheimer’s disease (AD) has increased by 145%. There are several common risk factors for Type 2 Diabetes and AD, including obesity, insulin resistance, and ageing, as well as common pathological mechanisms, including altered insulin signalling, oxidative stress, neuroinflammation, mitochondrial dysfunction, formation of glycated proteins and metabolic syndrome. This review aims to summarize the therapeutic effects of different nutritional therapy strategies on the reduction of DM and AD risk. Controlling blood sugar levels and reducing calorie intake is crucial to preventing diabetes and Alzheimer's disease. The low-carbohydrate, ketogenic, and Mediterranean diets have been found to improve glucose control in people with Type 2 diabetes (T2D). In addition, MIND (Mediterranean-DASH Diet Intervention for Neurodegenerative Delay) and a ketogenic diet may improve cognition in AD patients. Lactobacillus, Bifidobacterium probiotics, and prebiotics, such as inulin, may inhibit the progression of T2D and AD diseases by suppressing inflammation and modulating gut microbes. In addition, vitamins A, C, D, E, B6, B12, folate, long-chain polyunsaturated fatty acids, zinc, magnesium, and polyphenols may improve cognitive decline, homocysteine levels, and insulin resistance in AD and T2D patients. Healthcare professionals can use the results of this review to understand the beneficial effects of dietary strategies and multi-nutrient supplementation on DM and AD. However, further robust studies are required to investigate the risk factors and underlying mechanisms behind DM-combined AD progression.
Abstract
The combined disease burden of diabetes mellitus (DM) and Alzheimer's disease (AD) is increasing, and the two diseases share some common pathological changes. However, the pharmacotherapeutic approach to this clinical complexity is limited to symptomatic rather than disease-arresting, with the possible exception of metformin. Whether nutritional intervention might extend or synergize with these effects of metformin is of interest. In particular, dietary patterns with an emphasis on dietary diversity shown to affect cognitive function are of growing interest in a range of food cultural settings. This paper presents the association between diabetes and AD. In addition, the cross-cultural nutritional intervention programs with the potential to mitigate both insulin resistance (IR) and hyperglycemia, together with cognitive impairment are also reviewed. Both dietary patterns and nutritional supplementation showed the effects of improving glycemic control and reducing cognitive decline in diabetes associated with AD, but the intervention specificity remained controversial. Multi-nutrient supplements combined with diverse diets may have preventive and therapeutic potential for DM combined with AD, at least as related to the B vitamin group and folate-dependent homocysteine (Hcy). The nutritional intervention has promise in the prevention and management of DM and AD comorbidities, and more clinical studies would be of nutritional scientific merit.

Individuals with non-communicable diseases (NCD's), i.e. diseases that are not transmitted from person to person, such as diabetes and heart disease, are at a much higher risk of death from Covid-19. But for individuals who contract Covid-19 and survive, there could be considerable implications on the progression of their pre-existing condition. This review study aimed to discuss how the Covid-19 pandemic might impact management and outcomes in individuals with NCD's. The paper outlined that higher Covid-19 death rates in individuals with NCD's, will cause a decline of these diseases within populations. Although there is little peer reviewed research to support this, circumstantial reports are already suggesting lower hospital admissions for stroke and heart attacks. However it should be noted that it is obvious that this paper was written at the start of the pandemic. The paper went on to discuss that the pandemic and subsequent government actions to control the infection will affect individuals with NCD's through reductions in physical activity, social interaction, and vitamin D intake. Changes to medical management, the subsequent possibility of decreased adherence to medications and the halting of much needed research on NCD's in favour of Covid-19 research, will further exacerbate the impact on individuals with pre-existing conditions. Finally, areas upon which the healthcare system and government should be focusing in order to help individuals with NCD's were discussed. Amongst these was the acknowledgement that the public and private healthcare systems have collaborated with success and this should continue and that on-going support through technology such as Telehealth services and patient advocacy associations is a necessity. Clinicians could use this paper to understand how Covid-19 could accelerate disease progression in individuals with NCD’s and that close monitoring is essential. For individuals with NCD’s who do not have Covid-19, close monitoring would still be required to ensure that government strategies to contain the virus do not exacerbate their condition.
Abstract
The early stages of the COVID-19 pandemic have focused on containing SARS-CoV-2 infection and identifying treatment strategies. While controlling this communicable disease is of utmost importance, the long-term effect on individuals with non-communicable diseases (NCD) is significant. Although certain NCDs appear to increase the severity of COVID-19 and mortality risk, SARS-CoV-2 infection in survivors with NCDs may also affect the progression of their pre-existing clinical conditions. Infection containment measures will have substantial short- and long-term consequences; social distancing and quarantine restrictions will reduce physical activity and increase other unhealthy lifestyles, thus increasing NCD risk factors and worsening clinical symptoms. Vitamin D levels might decrease and there might be a rise in mental health disorders. Many countries have made changes to routine management of NCD patients, e.g., cancelling non-urgent outpatient visits, which will have important implications for NCD management, diagnosis of new-onset NCDs, medication adherence, and NCD progression. We may have opportunities to learn from this unprecedented crisis on how to leverage healthcare technologies and improve procedures to optimize healthcare service provision. This article discusses how the COVID-19 outbreak and related infection control measures could hit the most frail individuals, worsening the condition of NCD patients, while further jeopardizing the sustainability of the healthcare systems. We suggest ways to define an integrated strategy that could involve both public institutional entities and the private sector to safeguard frail individuals and mitigate the impact of the outbreak.

Plain language summary
Early reports have shown that individuals with diabetes who contract Covid-19 have higher hospital admissions and mortality rates, classing them as a vulnerable group. This review paper aimed to explain why this group of people are vulnerable and what measures could be recommended. The paper outlined that individuals with diabetes have a compromised immune system due to uncontrolled blood sugar levels. In addition to this, individuals with diabetes and Covid-19 may have a higher risk of organ damage due to the effects of the body's immune response combined with the disordered biological processes associated with their pre-existing condition. Conversely, it was discussed that Covid-19 could exacerbate diabetes progression if the Covid-19 virus entered the cells of the pancreas, causing a blood sugar imbalance. As a result, the importance of optimal blood sugar control was outlined. Several medications were addressed and their benefits/disadvantages discussed. Amongst those reviewed were medications such as GLP-1 agonists, which may help with controlling blood sugar levels and may prevent Covid-19 entering the body's own cells, and metformin, which was initially developed as an anti-influenza drug. Finally the paper discussed diabetes specific precautions to avoid contracting Covid-19. Vitamin D supplementation, regular blood sugar checks, lifestyle measures such as exercise and dietary requirements and allowing individuals with diabetes to have large supplies of their medications to avoid leaving the house were discussed. It was concluded that during the Covid-19 pandemic, individuals with diabetes require particular care in order to avoid additional burden on healthcare systems. For those individuals with diabetes who haven’t contracted Covid-19, this paper could be used to recommend any extra precautions to take to avoid contracting this virus.
Abstract
BACKGROUND The novel coronavirus SARS-CoV-2 has taken the world by storm. Alongside COVID-19, diabetes is a long-standing global epidemic. The diabetes population has been reported to suffer adverse outcomes if infected by COVID-19. The aim was to summarise information and resources available on diabetes and COVID-19, highlighting special measures that individuals with diabetes need to follow. METHODS A search using keywords "COVID-19" and "Diabetes" was performed using different sources, including PubMed and World Health Organization. RESULTS COVID-19 may enhance complications in individuals with diabetes through an imbalance in angiotension-converting enzyme 2 (ACE2) activation pathways leading to an inflammatory response. ACE2 imbalance in the pancreas causes acute β-cell dysfunction and a resultant hyperglycemic state. These individuals may be prone to worsened COVID-19 complications including vasculopathy, coagulopathy as well as psychological stress. Apart from general preventive measures, remaining hydrated, monitoring blood glucose regularly and monitoring ketone bodies in urine if on insulin is essential. All this while concurrently maintaining physical activity and a healthy diet. Different supporting entities are being set up to help this population. CONCLUSION COVID-19 is a top priority. It is important to remember that a substantial proportion of the world's population is affected by other co-morbidities such as diabetes. These require special attention during this pandemic to avoid adding on to the burden of countries' healthcare systems.
