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.

Miscarriage causes significant physical and psychological harm. Vitamin D deficiency (low serum levels of 25- hydroxyvitamin D) is a major global health concern, with pregnant women and those planning pregnancy at increased risk. The aim of this study was to evaluate the association between vitamin D status and pregnancy loss, including spontaneous miscarriage and recurrent miscarriage. This study is a systematic review and meta-analysis of ten studies (6 where observational studies and 4 interventional studies). Results show that women who were vitamin D deficient were at significantly increased risk of miscarriage compared with those who were vitamin D replete. This association was maintained when women with insufficient levels were included, with a biologic gradient evident. Authors conclude that new evidence-based interventions are required for women at risk of miscarriage.
Abstract
OBJECTIVE To investigate whether a significant association between vitamin D status and the risk of miscarriage or recurrent miscarriage (RM) exists. DESIGN Systematic review and meta-analysis. SETTING Not applicable. PATIENT(S): Women with miscarriage and RM. INTERVENTION(S): We searched the Ovid MEDLINE, Embase, the Cumulative Index to Nursing and Allied Health Literature, and Cochrane Central Register of Controlled Trials from database inception to May 2021. Randomized and observational studies investigating the association between maternal vitamin D status and miscarriage and/or vitamin D treatment and miscarriage were included. MAIN OUTCOME MEASURE(S): The primary outcome was miscarriage or RM, with vitamin D status used as the predictor of risk. Whether vitamin D treatment reduces the risk of miscarriage and RM was also assessed. RESULT(S): Of 902 studies identified, 10 (n = 7,663 women) were included: 4 randomized controlled trials (n = 666 women) and 6 observational studies (n = 6,997 women). Women diagnosed with vitamin D deficiency (<50 nmol/L) had an increased risk of miscarriage compared with women who were vitamin D replete (>75 nmol/L) (odds ratio, 1.94; 95% confidence interval, 1.25-3.02; 4 studies; n = 3,674; I2 = 18%). Combined analysis, including women who were vitamin D insufficient (50-75 nmol/L) and deficient (<50 nmol/L) compared with women who were replete (>75 nmol/L), found an association with miscarriage (odds ratio, 1.60; 95% confidence interval, 1.11-2.30; 6 studies; n = 6,338; I2 = 35%). Although 4 randomized controlled trials assessed the effect of vitamin D treatment on miscarriage, study heterogeneity, data quality, and reporting bias precluded direct comparison and meta-analysis. The overall study quality was "low" or "very low" using the Grading of Recommendations, Assessment, Development and Evaluations approach. CONCLUSION(S): Vitamin D deficiency and insufficiency are associated with miscarriage. Whether preconception treatment of vitamin D deficiency protects against pregnancy loss in women at risk of miscarriage remains unknown. REGISTRATION NUMBER CRD42021259899.

Plain language summary
Fibromyalgia (FM) is characterised by widespread chronic pain, fatigue, sleep disturbances, and cognitive impairment. As a result of oxidative stress, reactive oxygen species (ROS) are produced and improperly disposed of, resulting in peripheral and central sensitisations, and a reduction of the pain threshold in FM patients. It is well known that antioxidants are protective against oxidative stress and that reducing antioxidant levels can result in increased pain in patients with FM. An overview of 17 studies was conducted to evaluate the effect of antioxidant supplementation on pain perception and the appropriate duration of treatment for FM patients in this systematic review. This systematic review found that supplementation with Fibromyalgine® (Fib) (that contains vitamin C, acerola ginger root, and freeze-dried royal jelly), 300-400 gm/d of coenzyme Q10 alone in combination with Pregabalin, ferric carboxymaltose, vitamin C, E, and Nigella sativa, magnesium + amitriptyline, acetyl L-carnitine, and Sun Chlorella™ green algae are effective in reducing pain perception in FM patients. In patients with FM, alpha-lipoic acid supplementation significantly reduced pain scores. 80% of FM patients reported reduced pain after supplement treatment for at least six weeks. There is a need for further robust long-term studies to confirm the effectiveness and clinical applicability of antioxidants in the management of FM, as well as to identify the pathophysiology of FM. This research may, however, be used by healthcare professionals to gain a better understanding of the potential benefits of antioxidants in the treatment of pain associated with FM.
Abstract
In recent years, antioxidant supplements have become popular to counteract the effects of oxidative stress in fibromyalgia and one of its most distressing symptoms, pain. The aim of this systematic review was to summarize the effects of antioxidant supplementation on pain levels perceived by patients diagnosed with fibromyalgia. The words used respected the medical search terms related to our objective including antioxidants, fibromyalgia, pain, and supplementation. Seventeen relevant articles were identified within Medline (PubMed), Scopus, Web of Science (WOS), the Cochrane Database of Systematic Review, and the Cochrane Central Register of Controlled Trials. This review found that antioxidant supplementation is efficient in reducing pain in nine of the studies reviewed. Studies with a duration of supplementation of at least 6 weeks showed a benefit on pain perception in 80% of the patients included in these studies. The benefits shown by vitamins and coenzyme Q10 are remarkable. Further research is needed to identify the effects of other types of antioxidants, such as extra virgin olive oil and turmeric. More homogeneous interventions in terms of antioxidant doses administered and duration would allow the effects on pain to be addressed more comprehensively.

Plain language summary
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
Androgens, like testosterone, are steroid hormones commonly associated with reproduction. However, they also govern metabolic functions, body composition and growth. Higher levels of circulating androgens enhance athletic performance by supporting metabolic activities such as protein production, regeneration and growth and by inhibiting breakdown processes. Manipulating testosterone to enhance athletic performance without the use of anabolic steroids hormones has been of much interest. As macro-and micronutrients can influence androgen hormones, this review examined whether specific energy and nutrient intake can ‘naturally’ manipulate testosterone levels. The authors describe the metabolic functions of testosterone before exploring the current evidence on selected plant extracts and nutrients and their impact on aromatase activity. Inhibiting aromatase can prevent androgens from being converted into oestrogen and thus may help to raise circulating androgens. Discussed are a range of plant-derived compounds, flavonoids, macronutrients and micronutrients (Vitamin D, Zinc and Magnesium) and their impact on testosterone levels. The authors conclude that the nutrients discussed have some supportive evidence, yet overall findings are inconclusive due to limited studies. Regarding macronutrients more research is available, and the evidence supports that low energy intake negatively impacts testosterone levels and performance. Whereby supplementation of vitamins crucial to testosterone production seems to provide value in cases of deficiency further research is required. This article yields an overview of plant compounds, macro-and micronutrients and their potential impact on circulating testosterone levels. While low energy intake and nutrient deficiencies appears to be unfavourable, the absence of clear evidence on other compounds would warrant further case-specific investigations.
Abstract
Elevations in the circulating concentration of androgens are thought to have a positive effect on the anabolic processes leading to improved athletic performance. Anabolic-androgenic steroids have often been used by competitive athletes to augment this effect. Although there has been concerted effort on examining how manipulating training variables (e.g., intensity and volume of training) can influence the androgen response to exercise, there has been much less effort directed at understanding how changes in both macronutrient and micronutrient intake can impact the androgen response. Thus, the focus of this review is to examine the effect that manipulating energy and nutrient intake has on circulating concentrations of testosterone and what the potential mechanism is governing these changes.

The novel coronavirus pandemic of 2019 (COVID-19), an emerging infectious disease, is caused by multiple strains of Severe Acute Respiratory Syndrome Coronavirus-2. The main aim of this study was to outline the potential role of probiotics in fighting the COVID-19. This study focuses on recent evidence on the association between microbiota, probiotics, and COVID-19, the role of probiotics as an immune-modulator and antiviral agent. Findings support probiotics’ role in regulating the immune system, suggesting a definitive role for probiotics in viral infections. Thus, probiotics supplementation could reduce the severity of COVID-19 morbidity and mortality. Authors conclude that supplementation of probiotics in high risk and severely ill patients, and frontline health workers, may help to limit the infection and flatten the COVID-19 curve. However, further studies should be conducted for more conclusive evidence.
Abstract
Saving lives and flattening the curve are the foremost priorities during the ongoing pandemic spread of SARS-CoV-2. Developing cutting-edge technology and collating available evidence would support frontline health teams. Nutritional adequacy improves general health and immunity to prevent and assuage infections. This review aims to outline the potential role of probiotics in fighting the COVID-19 by covering recent evidence on the association between microbiota, probiotics, and COVID-19, the role of probiotics as an immune-modulator and antiviral agent. The high basic reproduction number (R0) of SARS-CoV-2, absence of conclusive remedies, and the pleiotropic effect of probiotics in fighting influenza and other coronaviruses together favour probiotics supplements. However, further support from preclinical and clinical studies and reviews outlining the role of probiotics in COVID-19 are critical. Results are awaited from many ongoing clinical trials investigating the benefits of probiotics in COVID-19.

Plain language summary
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.

Plain language summary
Endocrine and metabolic related diseases such as diabetes and obesity may increase the risk of developing severe Covid-19 and as a result these diseases could be severely affected by Covid-19 infection. This very large review paper looked at over 100 studies and outlined the interrelationship between Covid-19 infection and several endocrine diseases. Diabetes, obesity, pituitary-hypothalamic function, thyroid function, Cushing's syndrome and adrenal function were all reviewed. No aim was stated. Data on individuals with obesity and diabetes indicated an increased risk for severe Covid-19 infection, hospitalisation and mortality. Data surrounding pituitary-hypothalamic function, thyroid function, Cushing's syndrome and adrenal function was less abundant, however neurological issues in Covid-19 patients suggested an involvement of the pituitary and hypothalamus. In lieu of sufficient data the author commented on the possible similarities between severe acute respiratory syndrome coronavirus with the Covid-19 virus. A number of management strategies were discussed such as the use of vitamin D, oxytocin and melatonin, however the authors commented on the lack of data regarding oxytocin and melatonin in Covid-19 patients, but mechanistic data suggested they might be of use. No overall conclusions were drawn on the findings. Clinicians could use this paper to understand how patients with pre-existing endocrine and metabolic conditions may be at a higher risk of more severe Covid-19 and if contracted could exacerbate their pre-existing condition. These patients could require constant monitoring and additional measures to avoid contracting Covid-19. Supplements such as vitamin D, oxytocin or melatonin could be therapeutic, however more data needs to be reviewed.
Abstract
COVID-19 infection has tremendously impacted our daily clinical practice as well as our social living organization. Virtually all organs and biological systems suffer from this new coronavirus infection, either because the virus targets directly specific tissues or because of indirect effects. Endocrine diseases are not an exception and some of endocrine organs are at risk of direct or indirect lesion by COVID-19. Although there is still no evidence of higher predisposition to contract the infection in patients with diabetes and/or obesity, the coexistence of these conditions contributes to a worse prognosis because both conditions confer an impaired immunologic system. Cytokines storm can be amplified by these two latter conditions thereby leading to multisystemic failure and death. Glycaemic control has been demonstrated to be crucial to avoiding long hospital stays, ICU requirement and also prevention of excessive mortality. Endocrine treatment modifications as a consequence of COVID-19 infection are required in a proactive manner, in order to avoid decompensation and eventual hospital admission. This is the case of diabetes and adrenal insufficiency in which prompt increase of insulin dosage and substitutive adrenal steroids through adoption of the sick day's rules should be warranted, as well as easy contact with the health care provider through telematic different modalities. New possible endocrinological targets of COVID-19 have been recently described and warrant a full study in the next future.
