Plain language summary
The use of androgen deprivation therapy (ADT) has coincided with improvements in disease control and improved overall survivorship in many men treated for prostate cancer. Exercise and nutrition interventions during and/or after ADT are strongly recommended to mitigate or improve body composition and reduce cardiometabolic side effects. The aim of this study was to examine the combined effects of a Mediterranean diet (MED-diet) and high intensity interval training (HIIT) on cardiorespiratory fitness, body composition and quality of life, compared to usual care, in men with prostate cancer treated with ADT. This study is a two-arm randomised controlled trial. Participants (n = 23) were randomly allocated to either an intervention or usual care group in a 1:1 ratio. Results show that for men with prostate cancer undergoing ADT, a MED-diet with HIIT compared to usual care at 20 weeks (i) significantly improved cardiorespiratory fitness relative; (ii) reduced body weight; (iii) maintained lean body mass despite achieving weight loss; (iv) significantly improved vitality and mental health composite, and clinical improvements were seen in prostate-cancer specific quality of life and cancer-related fatigue. Authors conclude that future larger-scale trials examining the MED-diet with HIIT on cardiorespiratory fitness, body composition and quality of life would help to extend the findings of their study.
Abstract
Background: Androgen deprivation therapy (ADT) in prostate cancer has been shown to deteriorate body composition (reduced lean mass and increased body and fat mass) and increase the risk of cardiovascular morbidity. The Mediterranean style dietary pattern (MED-diet) and high intensity interval training (HIIT) may synergistically alleviate these side effects and improve quality of life in men treated with ADT. Methods: Twenty-three men (65.9 ± 7.8 years; body mass index: 29.6 ± 2.7 kg/m2; ADT duration: 33.8 ± 35.6 months) receiving ADT for ≥3 months were randomly assigned (1:1) to 20 weeks of usual care or the MED-diet (10 nutrition consults) with HIIT (4 × 4 min 85−95% heart rate peak, 3× week, starting at 12 weeks). Results: The MED-diet with HIIT significantly improved cardiorespiratory fitness (+4.9 mL·kg−1·min, p < 0.001), and body mass (−3.3 kg, p < 0.001) compared to the usual care group at 20 weeks. Clinically meaningful (≥3 points) improvements were seen in quality of life and cancer-related fatigue after 20 weeks. Conclusions: The MED-diet with HIIT increased cardiorespiratory fitness and reduced body weight in men with prostate cancer treated with ADT. Larger trials determining whether the MED-diet with HIIT translates to cardiovascular benefits are warranted.

Plain language summary
The low-FODMAP diet eliminates carbohydrates that cannot be easily digested in order to reduce functional gastrointestinal symptoms associated with irritable bowel disease (IBD). The symptoms of irritable bowel disease include abdominal pain and bloating. This systematic review and meta-analysis aimed to evaluate whether a low-FODMAP diet can alleviate functional gastrointestinal symptoms in individuals with inflammatory bowel disease. In comparison with a regular diet, a low-FODMAP diet significantly reduced symptoms of bloating, wind, flatulence, abdominal pain, fatigue, and lethargy in patients with IBD. In addition, patients with Crohn's disease have achieved remission or reduced symptoms after following a low-FODMAP diet. Healthcare professionals can use this study to understand better the effects of a low-FODMAP diet on patients with IBD who have functional gastrointestinal symptoms. Further robust studies are, however, required to evaluate the evidence's robustness and identify the mechanism behind the improvement of symptoms.

Summary Review:
Introduction
This meta-analysis assesses the efficacy of a low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols diet (LFD) in inflammatory bowel disease [IBD: ulcerative colitis (UC) and Crohn’s disease (UC)] participants with functional gastrointestinal symptoms (FGSs).
Methods
A search was performed on PubMed, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure (CNKI), WanFang (Chinese) Database up to March 2022. Quality assessment of all included studies was performed.
Results
9 studies (4 randomised controlled trials, 5 non-randomised studies) with a total of 351 participants diagnosed with IBD were included, and compared LFD with a placebo diet or normal diet (ND), overall and individual
LFD Effects of FGS:
- Overall 9 studies: an improvement (0.47, 0.33–0.66, p = 0.0000)
- No difference in the subgroup classified by disease type
- CD and UC: no improvement
Individual improvement:
- Bloating (0.37, 0,24-0,57, p=0.0000); wind or flatulence (0.38, 0,28-0,51, p=0.0000); borborygmi (0.48, 0,26-0,89, p=0.0000), abdominal pain (0.5, 0,37-0,68, p=0.0000), fatigue/lethargy (0.71, 0,61-0,82, p=0.0000)
- No difference in nausea and vomiting (0.54, 0,22-1,32, p=018)
IBS Quality of Life Score:
- 2 studies: reduced Short IBD Questionnaire (SIBDQ) score (11.24, 6.61-15.87, p=0.0000)
Bristol Stool Form Chart:
- 2 studies: normal stool consistency (type 3-4); no difference (5.99, 0.17-216.51, p=0.33)
- 2 other studies: no difference (-0.17, 0.48 - 0.15, p=0.30)
Diseases activity (Harvey-Bradshaw index):
- 2 studies using the Mayo score: no difference (-32, -1,09-0.45, p=0.41)
- 3 studies using BHi score: reduction (-1.09, -1,77-0.42, p=0.002)
Faecal calprotectin:
- 2 studies: no change (-16.03, -36,78-4.73, p=0.13)
Limitations
- Comparison diets were not standardised, suggesting the potential of different dietary habits to bias results..
- Heterogeneity of included studies, and the relatively small sample size of the studies can reduce the reliability of the results.
Conclusion
While the study found inconsistent definition standards for FGS, all the nine studies showed that LFD was associated with an improvement in some symptoms.
Clinical practice applications:
- This study suggests that IBD patients with FGSs may benefit from LFD treatment with the assistance of a healthcare professional.
Considerations for future research:
- This study has shown that LFD can improve FGSs in IBD, but further research with a larger sample size and more comprehensive analysis is warranted to replicate the results.
- The description of the findings and Quality of Life data are a little unclear. The impact on Quality of Life warrants further investigation, as clinicians need to consider the impact of following a restrictive diet on Quality of Life.
Abstract
BACKGROUND A low fermentable oligosaccharides, disaccharides, monosaccharides, and polyols diet (LFD) is claimed to improve functional gastrointestinal symptoms (FGSs). However, the role of LFD in inflammatory bowel disease (IBD) patients with FGSs remains unclear. OBJECTIVE To systematically assess the efficacy of LFD in IBD patients with FGSs. METHODS Six databases were searched from inception to 1 January 2022. Data were synthesized as the relative risk of symptoms improvement and normal stool consistency, mean difference of Bristol Stool Form Scale (BSFS), Short IBD Questionnaire (SIBDQ), IBS Quality of Life (IBS-QoL), Harvey-Bradshaw index (HBi), Mayo score, and fecal calprotectin (FC). Risk of bias was assessed based on study types. A funnel plot and Egger's test were used to analyze publication bias. RESULTS This review screened and included nine eligible studies, including four randomized controlled trials (RCTs) and five before-after studies, involving a total of 446 participants (351 patients with LFD vs. 95 controls). LFD alleviated overall FGSs (RR: 0.47, 95% CI: 0.33-0.66, p = 0.0000) and obtained higher SIBDQ scores (MD = 11.24, 95% CI 6.61 to 15.87, p = 0.0000) and lower HBi score of Crohn's disease (MD = -1.09, 95% CI -1.77 to -0.42, p = 0.002). However, there were no statistically significant differences in normal stool consistency, BSFS, IBS-QoL, Mayo score of ulcerative colitis, and FC. No publication bias was found. CONCLUSIONS LFD provides a benefit in FGSs and QoL but not for improving stool consistency and mucosal inflammation in IBD patients. Further well-designed RCTs are needed to develop the optimal LFD strategy for IBD.

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
COVID-19 has been found to cause neurological manifestations in up to 50% of patients. The aim of this study was to inform future service provision for those who develop long-term neurological symptoms due to COVID-19, as well as exploring the effect of COVID-19 on health professionals’ perceptions towards those with symptoms of functional neurological disorder (FND). This study is a systematic overview of current systematic reviews which included 45 studies in qualitative synthesis. Results show that: - COVID-19 appears to be becoming chronic for some patients, presenting similar neurological symptoms to FND and to chronic fatigue syndrome; - the long-term neurological effects of COVID-19 may impact neurological and wider health care services; - the neurological symptoms seen in COVID-19 may affect health professionals’ perceptions of FND and chronic fatigue syndrome. Authors conclude that there is increasing evidence of the presence of long-COVID symptoms persisting beyond 3 months. Further research is recommended to explore whether the neurological symptoms of COVID-19 will improve acceptance and understanding of FND, or whether this will worsen the experience for those who suffer from FND.
Abstract
AIMS: In response to the rapid spread of COVID-19, this paper provides health professionals with better accessibility to available evidence, summarising findings from a systematic overview of systematic reviews of the neurological symptoms seen in patients with COVID-19. Implications of so-called 'Long Covid' on neurological services and primary care and similarities with other neurological disorders are discussed. METHODS Firstly, a systematic overview of current reviews of neurological symptoms of COVID-19 was conducted. Secondly, the implications of these findings are discussed in relation to the potential effect on neurological services and the similarities in the experience of patients with COVID-19 and those with other neurological disorders. A total of 45 systematic reviews were identified within seven databases, published between 11 April 2020 and 15 October 2020, following a search in June 2020, updated on 20 October 2020. RESULTS The results indicated that COVID-19 exhibits two types of neurological symptoms; life-threatening symptoms such as Guillain-Barre Syndrome (GBS) and encephalitis, and less devastating symptoms such as fatigue and myalgia. Many of these so-called lesser symptoms appear to be emerging as longer-term for some sufferers and have been recently labelled Long Covid. When compared, these less devastating symptoms are very similar to other neurological conditions such as chronic fatigue syndrome (CFS) and functional neurological disorder (FND). CONCLUSION Implications for neurological healthcare services in the United Kingdom (UK) may include longer waiting times and a need for more resources (including more qualified health professionals). There is also a possible change-effect on health professionals' perceptions of other neurological conditions such as CFS and FND. Future research is recommended to explore changes in health professionals' perceptions of neurological symptoms because of COVID-19.

Plain language summary
Fatigue often occurs as a symptom of severe diseases. It is currently coming into focus as a major symptom of long COVID. The aim of this study was to provide a feasibility analysis of whether the use of intravenous (IV) vitamin C in post-viral fatigue, particularly after COVID-19, should be further investigated. This study is a review which included nine clinical studies compromising of 720 participants. Three of the four randomised-controlled trials showed a significant decrease in fatigue in patients having high-dose vitamin C compared to their controls. Similarly, four of the five observational studies observed a significant reduction in fatigue. Authors conclude that the effects of IV vitamin C on post-viral COVID-19 fatigue should be investigated in clinical trials.
Abstract
Fatigue is common not only in cancer patients but also after viral and other infections. Effective treatment options are still very rare. Therefore, the present knowledge on the pathophysiology of fatigue and the potential positive impact of treatment with vitamin C is illustrated. Additionally, the effectiveness of high-dose IV vitamin C in fatigue resulting from various diseases was assessed by a systematic literature review in order to assess the feasibility of vitamin C in post-viral, especially in long COVID, fatigue. Nine clinical studies with 720 participants were identified. Three of the four controlled trials observed a significant decrease in fatigue scores in the vitamin C group compared to the control group. Four of the five observational or before-and-after studies observed a significant reduction in pre-post levels of fatigue. Attendant symptoms of fatigue such as sleep disturbances, lack of concentration, depression, and pain were also frequently alleviated. Oxidative stress, inflammation, and circulatory disorders, which are important contributors to fatigue, are also discussed in long COVID fatigue. Thus, the antioxidant, anti-inflammatory, endothelial-restoring, and immunomodulatory effects of high-dose IV vitamin C might be a suitable treatment option.

Plain language summary
SARS-CoV-2 infection (COVID-19) is a major pandemic resulting in considerable mortality and morbidity worldwide. For some people who recover from COVID-19, symptoms persist or new ones develop for weeks or months after infection despite testing PCR negative. This is termed long-COVID or post-COVID syndrome and divided into two stages: post-acute-COVID with symptoms extending beyond three weeks, and chronic-COVID with symptoms extending beyond 12 weeks. Factors that increase the risk for long-COVID include being female, age, having more than five symptoms in the acute stage of infection and pre-existing health conditions. A mild disease course is not exclusive to long-COVID. Typically affected by long-COVID are the pulmonary or cardiovascular system, with neuropsychiatric presentations also being reported. Common symptoms are one or more of the following such as fatigue, breathlessness, cough, chest pain, heart racing, headache, joint pain, muscle pain and weakness, insomnia, pins and needles, diarrhoea, rash, hair loss, impaired balance, neurocognitive issues. Due to the novelty of the virus, the underline pathophysiology of long-COVID still requires further investigation. Contributing factors mentioned include: compromised body functions after illness and inactivity, organ damage, persistent inflammation, altered immune response and auto-antibody generation and viral persistence. The impact of medication, treatments, hospitalisation or associated post-traumatic stress is also urged to be accounted for. Diagnosis of long-COVID is made by thorough history taking, clinical examination and the exclusion of other conditions. For the management of long-COVID, the authors in this review suggest the sub-categorisation depending on the body system most affected to optimize treatment options. Furthermore, it is encouraged that medical treatment should also consider the monitoring for worsening of any pre-existing health conditions post-infection. This review yields a informative summary of the definition, symptom presentations, risk factors, diagnosis and medical treatment options relating to long-COVID.
Abstract
BACKGROUND AND AIMS Long COVID is the collective term to denote persistence of symptoms in those who have recovered from SARS-CoV-2 infection. METHODS WE searched the pubmed and scopus databases for original articles and reviews. Based on the search result, in this review article we are analyzing various aspects of Long COVID. RESULTS Fatigue, cough, chest tightness, breathlessness, palpitations, myalgia and difficulty to focus are symptoms reported in long COVID. It could be related to organ damage, post viral syndrome, post-critical care syndrome and others. Clinical evaluation should focus on identifying the pathophysiology, followed by appropriate remedial measures. In people with symptoms suggestive of long COVID but without known history of previous SARS-CoV-2 infection, serology may help confirm the diagnosis. CONCLUSIONS This review will helps the clinicians to manage various aspects of Long COVID.

Plain language summary
Chronic Fatigue Syndrome/Myalgic Encephalomyelits (CFS/ME) is a severe multisystemic disease. The main symptom is persistent unexplained fatigue, it has inflammatory symptoms, is characterized by an abnormal immune response and dysfunction of energy metabolism. Recent studies suggest strong correlations between dysbiosis and other conditions such as intestinal disorders, autoimmune conditions, cancer and several neurological disorders. In the case of CFS/ME, some studies have shown an altered composition of the gut and oral microbiomes. In this study the oral and intestinal bacterial composition of CFS/ME patients were analysed and compared to a group of relatives and to a control population outside the families. This was to identify a possible effect of lifestyle habits and a microbial profile of CFS/ME syndrome. The study showed significant variations in both the intestinal and oral bacteria composition between CFS/ME patients, their relatives and external controls. There is a lot of interesting detail about the levels of specific bacteria in each group. Further studies are needed to better understand if the microbial composition changes are cause or consequence of the onset of CFS/ME and if they are related to any of the several secondary symptoms.
Abstract
Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (CFS/ME) is a severe multisystemic disease characterized by immunological abnormalities and dysfunction of energy metabolism. Recent evidences suggest strong correlations between dysbiosis and pathological condition. The present research explored the composition of the intestinal and oral microbiota in CFS/ME patients as compared to healthy controls. The fecal metabolomic profile of a subgroup of CFS/ME patients was also compared with the one of healthy controls. The fecal and salivary bacterial composition in CFS/ME patients was investigated by Illumina sequencing of 16S rRNA gene amplicons. The metabolomic analysis was performed by an UHPLC-MS. The fecal microbiota of CFS/ME patients showed a reduction of Lachnospiraceae, particularly Anaerostipes, and an increased abundance of genera Bacteroides and Phascolarctobacterium compared to the non-CFS/ME groups. The oral microbiota of CFS/ME patients showed an increase of Rothia dentocariosa. The fecal metabolomic profile of CFS/ME patients revealed high levels of glutamic acid and argininosuccinic acid, together with a decrease of alpha-tocopherol. Our results reveal microbial signatures of dysbiosis in the intestinal microbiota of CFS/ME patients. Further studies are needed to better understand if the microbial composition changes are cause or consequence of the onset of CFS/ME and if they are related to any of the several secondary symptoms.

Abstract
Around one in ten patients who recovered from Covid-19 are experiencing post-viral infection symptoms, also referred to as long Covid syndrome. This currently widespread condition seems to mirror symptoms of post-viral myalgic encephalomyelitis (ME) aka chronic fatigue syndrome (CFS), a chronic condition that still struggles to be understood. These symptoms include: extreme tiredness, brain fog, joints ache and flu-like symptoms. While long Covid has already drawn the attention of national institutes for research and is being clinically recognised as a condition, ME sufferers feel neglected and unheard. The article aims to explain how the surge in long Covid research fundings could be a turning point for the ME community too, “even when some patients may feel it’s too little too late”.
