Plain language summary
Myalgic encephalomyelitis, also known as Chronic Fatigue Syndrome (ME/ CFS), is a disease characterized by an inability to exert oneself physically, often coupled with a combination of other symptoms, including sleep disorders, severe unpredictable pain, and compromised cognitive abilities. The aim of this review was to delineate a number of the more prominent treatments for ME/CFS into different categories and evaluate the methods and results of corresponding drug trials. Results indicate that: • antiviral drugs appear to show limited efficacy in treating ME/CFS over a broad demographic. • there is a lack of clinical research focusing on the use of specific cyclooxygenase-2 inhibitors [analgesic] to treat ME/CFS. • antidepressants may be of use in delivering improvements in the quality of life of patients with ME/CFS. • recalibration of endocrine-immune regulation may be involved in supporting the persistence of ME/CFS and may be responsible at least in part for its resistance to single agent interventions. Authors conclude that there is a great need for larger, longitudinal studies focused on a more clearly defined subset of ME/CFS as well as a greater consideration of potential synergies between interventions and the suitability of combination therapies.
Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating disorder characterized by prolonged periods of fatigue, chronic pain, depression, and a complex constellation of other symptoms. Currently, ME/CFS has no known cause, nor are the mechanisms of illness well understood. Therefore, with few exceptions, attempts to treat ME/CFS have been directed mainly toward symptom management. These treatments include antivirals, pain relievers, antidepressants, and oncologic agents as well as other single-intervention treatments. Results of these trials have been largely inconclusive and, in some cases, contradictory. Contributing factors include a lack of well-designed and -executed studies and the highly heterogeneous nature of ME/CFS, which has made a single etiology difficult to define. Because the majority of single-intervention treatments have shown little efficacy, it may instead be beneficial to explore broader-acting combination therapies in which a more focused precision-medicine approach is supported by a systems-level analysis of endocrine and immune co-regulation.

Anxiety and its related conditions are highly prevalent on a global scale. A potential solution for people with anxiety is Acceptance and Commitment Therapy (ACT)—a psychological treatment that teaches mindfulness skills to help people accept their anxiety and commit to living in accordance with personal values. The aim of this study was to provide a comprehensive and up-to-date account on the empirical status of internet-delivered ACT for anxiety. This study is a systemic review of 20 studies. More than half of the studies were randomised control trials. Findings indicate small-to-large anxiety reductions among participants (suffering from generalized anxiety disorder, social anxiety disorder and illness anxiety disorder) after internet-derived ACT on standardized measures (studies n=18), thus indicating the beneficial impact of internet-derived ACT on anxiety. Authors conclude that their current findings indicate that internet-derived ACT can be an effective and acceptable treatment for some anxiety conditions among young to middle aged adults in Western societies.
Abstract
BACKGROUND Anxiety conditions are debilitating and prevalent throughout the world. Acceptance and Commitment Therapy (ACT) is an effective, acceptance-based behavioral therapy for anxiety. However, there are treatment barriers (eg, financial, geographical, and attitudinal), which prevent people from accessing it. To overcome these barriers, internet-delivered ACT (iACT) interventions have been developed in recent years. These interventions use websites to deliver ACT information and skill training exercises on the Web, either as pure self-help or with therapist guidance. OBJECTIVE This systematic review aimed to examine the therapeutic impact of iACT on all anxiety conditions. METHODS The EMBASE, MEDLINE, ProQuest Central, PsycINFO, Scopus, and Web of Science databases were searched up to September 2018. The titles and abstracts of remaining records after deduplication were screened by 2 authors with a total of 36 full-text articles being retained for closer inspection next to eligibility criteria. Empirical studies of all designs, population types, and comparator groups were included if they appraised the impact of iACT treatment on any standardized measure of anxiety. Included studies were appraised on methodological quality and had their data extracted into a standardized coding sheet. Findings were then tabulated, and a narrative synthesis was performed because of the heterogeneity found between studies. RESULTS A total of 20 studies met inclusion criteria. There were 11 randomized controlled trials (RCTs) and 9 uncontrolled pilot studies. Participants across all studies were adults. The anxiety conditions treated were as follows: generalized anxiety disorder (GAD), social anxiety disorder (SAD), illness anxiety disorder (IAD), and general anxiety symptoms, with or without comorbid physical and mental health problems. A total of 18 studies reported significant anxiety reduction after iACT treatment. This was observed in studies that delivered iACT with (n=13) or without (n=5) therapist guidance. The average attrition rate across all included studies during the active iACT treatment phase was 19.19%. In the 13 studies that assessed treatment satisfaction, participants on average rated their iACT experience with above average to high treatment satisfaction. CONCLUSIONS These findings indicate that iACT can be an efficacious and acceptable treatment for adults with GAD and general anxiety symptoms. More RCT studies are needed to corroborate these early iACT findings using empirical treatments in active control groups (eg, internet-delivered cognitive behavioral therapy). This would potentially validate the promising results found for SAD and IAD as well as address the full spectrum of anxiety disorders.

Plain language summary
The prevalence of psychological stress among farmers and farm workers is greater than that of non-farmers. The mental health of farmers can be affected by several factors, including pesticide exposure, financial problems, climate issues, and poor physical health. A total of 167 studies are included in this systematic review incorporating data from the studies conducted in 34 countries, including the United Kingdom, the United States and Australia. There is a need for risk assessment that influences farmers' mental health, according to this systematic review. There is a need for more robust studies to evaluate the impact of climate change and pesticide exposure on farmers' mental health and to determine which strategies can be used to help them find therapies. Using the results of this systematic review, healthcare professionals can raise awareness about mental health issues and assist farmers in identifying the symptoms, allowing them to seek help.
Abstract
Recently, concern has increased globally over farmers' mental health issues. We present a systematic review of the outcomes, locations, study designs, and methods of current studies on farmers' mental health. In particular, this review aims to fill an important gap in understanding of the potential key risk factors affecting farmers' mental health around the world. 167 articles on farmer mental health were included in a final systematic review using a standardized electronic literature search strategy and PRISMA guidelines. The four most-cited influences on farmers' mental health in the reviewed literature respectively were pesticide exposure, financial difficulties, climate variabilities/drought, and poor physical health/past injuries. The majority of studies were from developed countries, most specifically from the United States, Australia, and the United Kingdom. Comparative studies on the mental health of farmers and other occupational workers showed mixed results, with a larger portion identifying that psychological health disturbances were more common in farmers and farm-workers. Knowledge of farmer psychological disorder risk factors and its impacts are essential for reducing the burden of mental illness. Further research will be required on climate change impacts, developing country farmers' mental health, and information on how to reduce help-seeking barriers amongst farmers.

Fluoride is added to the water supply in some parts of the UK, US and Canada to help prevent tooth decay. However, some people think that fluoride could be harmful to health, and may affect brain development in foetuses. The aim of this Canadian study was to determine whether a mother’s exposure to fluoride during pregnancy was associated with her child’s IQ. Researchers recruited a total of 369 pregnant women from both fluoridated and non-fluoridated areas and measured the amount of fluoride in their urine. The children’s IQs were measured when they were aged 3 to 4 years. The researchers found that overall, maternal exposure to higher levels of fluoride during pregnancy was associated with lower IQ scores in children aged 3 to 4 years. The relationship was much stronger in boys than it was in girls. These findings indicate a possible need to reduce fluoride intake during pregnancy.
Abstract
IMPORTANCE The potential neurotoxicity associated with exposure to fluoride, which has generated controversy about community water fluoridation, remains unclear. OBJECTIVE To examine the association between fluoride exposure during pregnancy and IQ scores in a prospective birth cohort. DESIGN, SETTING, AND PARTICIPANTS This prospective, multicenter birth cohort study used information from the Maternal-Infant Research on Environmental Chemicals cohort. Children were born between 2008 and 2012; 41% lived in communities supplied with fluoridated municipal water. The study sample included 601 mother-child pairs recruited from 6 major cities in Canada; children were between ages 3 and 4 years at testing. Data were analyzed between March 2017 and January 2019. EXPOSURES Maternal urinary fluoride (MUFSG), adjusted for specific gravity and averaged across 3 trimesters available for 512 pregnant women, as well as self-reported maternal daily fluoride intake from water and beverage consumption available for 400 pregnant women. MAIN OUTCOMES AND MEASURES Children's IQ was assessed at ages 3 to 4 years using the Wechsler Primary and Preschool Scale of Intelligence-III. Multiple linear regression analyses were used to examine covariate-adjusted associations between each fluoride exposure measure and IQ score. RESULTS Of 512 mother-child pairs, the mean (SD) age for enrollment for mothers was 32.3 (5.1) years, 463 (90%) were white, and 264 children (52%) were female. Data on MUFSG concentrations, IQ scores, and complete covariates were available for 512 mother-child pairs; data on maternal fluoride intake and children's IQ were available for 400 of 601 mother-child pairs. Women living in areas with fluoridated tap water (n = 141) compared with nonfluoridated water (n = 228) had significantly higher mean (SD) MUFSG concentrations (0.69 [0.42] mg/L vs 0.40 [0.27] mg/L; P = .001; to convert to millimoles per liter, multiply by 0.05263) and fluoride intake levels (0.93 [0.43] vs 0.30 [0.26] mg of fluoride per day; P = .001). Children had mean (SD) Full Scale IQ scores of 107.16 (13.26), range 52-143, with girls showing significantly higher mean (SD) scores than boys: 109.56 (11.96) vs 104.61 (14.09); P = .001. There was a significant interaction (P = .02) between child sex and MUFSG (6.89; 95% CI, 0.96-12.82) indicating a differential association between boys and girls. A 1-mg/L increase in MUFSG was associated with a 4.49-point lower IQ score (95% CI, -8.38 to -0.60) in boys, but there was no statistically significant association with IQ scores in girls (B = 2.40; 95% CI, -2.53 to 7.33). A 1-mg higher daily intake of fluoride among pregnant women was associated with a 3.66 lower IQ score (95% CI, -7.16 to -0.14) in boys and girls. CONCLUSIONS AND RELEVANCE In this study, maternal exposure to higher levels of fluoride during pregnancy was associated with lower IQ scores in children aged 3 to 4 years. These findings indicate the possible need to reduce fluoride intake during pregnancy.

Studies have shown an association between swimming in chemically-treated pools and a higher risk of asthma in children, although the mechanism is not fully understood. This study aimed to investigate how swimming pool attendance influences lung and nervous system function in school-aged children. Around 800 children were classified as current swimmers (CS), past swimmers (PS) or non-swimmers (NS). The children underwent several tests to determine their lung function and allergic response to common allergens. Parasympathetic nervous system function was tested by measuring the speed at which their pupils constricted in response to light. The current swimmers group had significantly lower pupil constriction speeds compared to PS and NS, suggesting a poorer functioning of the autonomic nervous system, possibly due to inflammation resulting from swimming pool chemical exposure. CS experienced greater constriction of the airways compared to NS. A non-significant trend for a higher risk of asthma, atopic eczema and rhinitis, was observed in swimmers. The authors concluded that swimming pool attendance appears to be associated with autonomic nervous system changes and increased baseline airway smooth muscle constriction even in children without asthma.
Abstract
BACKGROUND Endurance swimming exercises coupled to disinfection by-products exposure has been associated with increased airways dysfunction and neurogenic inflammation in elite swimmers. However, the impact of swimming pool exposure at a recreational level on autonomic activity has never been explored. Therefore, this study aimed to investigate how swimming pool attendance is influencing lung and autonomic function in school-aged children. METHODS A total of 858 children enrolled a cross sectional survey. Spirometry and airway reversibility to beta-2 agonist, skin-prick-tests and exhaled nitric oxide measurements were performed. Pupillometry was used to evaluate autonomic nervous function. Children were classified as current swimmers (CS), past swimmers (PS) and non-swimmers (NS), according to the amount of swimming practice. RESULTS Current swimmers group had significantly lower maximum and average pupil constriction velocities when compared to both PS and NS groups (3.8 and 5.1 vs 3.9 and 5.3 vs 4.0 and 5.4 mm/s, p = 0.03 and p = 0.01, respectively). Moreover, affinity to the beta-2 agonist and levels of exhaled nitric oxide were significantly higher in CS when compared to NS (70 vs 60 mL and 12 vs 10 ppb, p<0.01 and p = 0.03, respectively). A non-significant trend for a higher risk of asthma, atopic eczema and allergic rhinitis was found with more years of swimming practice, particularly in atopic individuals (β = 1.12, 1.40 and 1.31, respectively). After case-case analysis, it was possible to observe that results were not influenced by the inclusion of individuals with asthma. CONCLUSIONS Concluding, swimming pool attendance appears to be associated with autonomic changes and increased baseline airway smooth muscle constriction even in children without asthma.

Selecting foods for a day is easily influenced by the social environment and eating together or alone plays a big role in that decision. The study aims to evaluate the association between diet quality of the modern Korean adult population based on the eating behaviour and the socioeconomic factors that influence their diet quality. The study is a cross-sectional study which included 3365 men and 5258 women aged between 19 and 64 years. The study included demographic, socioeconomics, and health behaviour factors as covariates. Results indicate that diet quality is influence by eating behaviour. Authors observed that when Korean adults ate without a companion, their diet quality was significantly lower than those who consistently ate with others. Furthermore, from the higher education to lower education level, the diet quality declined when they eat alone. Authors conclude that many Korean adults are experiencing low diet quality when they eat alone. The study provides evidence to promote interventions to improve diet quality among the public.
Abstract
BACKGROUND To discover the association between eating alone and diet quality among Korean adults who eat alone measured by the mean adequacy ratio (MAR), METHODS The cross-sectional study in diet quality which was measured by nutrient intakes, indicated as MAR and nutrient adequacy ratio (NAR) with the Korean National Health and Nutrition Examination Survey (KNHANES) VI 2013-2015 data. Study population was 8523 Korean adults. Multiple linear regression was performed to identify the association between eating behaviour and MAR and further study analysed how socioeconomic factors influence the diet quality of those who eat alone. RESULTS We found that the diet quality of people who eat alone was lower than that of people who eat together in both male (β: - 0.110, p = 0.002) and female participants (β: - 0.069, p = 0.005). Among who eats alone, the socioeconomic factors that negatively influenced MAR with the living arrangement, education level, income levels, and various occupation classifications. CONCLUSIONS People who eat alone have nutrition intake below the recommended amount. This could lead to serious health problems not only to those who are socially disadvantaged but also those who are in a higher social stratum. Policy-makers should develop strategies to enhance diet quality to prevent potential risk factors.

Food prices are a key driver of food purchasing behaviours, and The Supermarket Healthy Eating for Life (SHELf) study has shown that price discounts on healthier foods can increase their purchase. The aim of this study was to quantify whether participants in the SHELf study switched to study supermarkets for purchasing their FV during the intervention because of the discounted price. 642 participants completed self-reported surveys on the proportion of FV purchased at the study supermarket at baseline, 3 months and 6 months post intervention. This study found that it is likely that participants switched supermarket choice during the intervention to purchase their FV from the study supermarkets. The authors conclude that unless food-purchasing data are available from all sources, differential changes in purchasing patterns can make it difficult to discern the effectiveness of nutrition interventions.
Abstract
BACKGROUND The impacts of supermarket-based nutrition promotion interventions might be overestimated if participants shift their proportionate food purchasing away from their usual stores. This study quantified whether participants who received price discounts on fruits and vegetables (FV) in the Supermarket Healthy Eating for Life (SHELf) randomized controlled trial (RCT) shifted their FV purchasing into study supermarkets during the intervention period. METHODS Participants were 642 females randomly assigned to a 1) skill-building (n = 160), 2) price reduction (n = 161), 3) combined skill-building and price reduction (n = 160), or 4) control (n = 161) group. Participants self-reported the proportion of FV purchased in study supermarkets at baseline, 3- and 6-months post-intervention. Fisher's exact and χ2 tests assessed differences among groups in the proportion of FV purchased in study supermarkets at each time point. Multinomial logistic regression assessed differences among groups in the change in proportionate FV purchasing over time. RESULTS Post-intervention, 49% of participants purchased ≥50% of their FV in study supermarkets. Compared to all other groups, the price reduction group was approximately twice as likely (RRR: 1.8-2.2) to have increased proportionate purchasing of FV in study supermarkets from baseline to post-intervention (p< 0.05). CONCLUSIONS Participants who received price reductions on FV were approximately twice as likely to shift their FV purchasing from other stores into study supermarkets during the intervention period. Unless food purchasing data are available for all sources, differential changes in purchasing patterns can make it difficult to discern the true impacts of nutrition interventions.

Children with autism spectrum disorders (ASD) often suffer gastrointestinal problems, such as constipation or diarrhea, the severity of which often correlate with ASD severity. This open-label clinical trial evaluated the impact of Microbiota Transfer Therapy (MTT) on GI and ASD symptoms of 18 ASD-diagnosed children. Treatment involved 2 weeks of antibiotic treatment and a bowel cleanse, followed by extended fecal microbiota transplant using a high initial dose and lower maintenance doses for 7-8 weeks. Results showed significant improvements in GI symptoms, which persisted 8 weeks after treatment ended. Bacterial diversity also increased. Behavioural ASD symptoms also improved significantly and lasted 8 weeks after treatment finished. This exploratory study suggests a promising approach to alter the gut microbiome in ASD subjects, improving GI and behavioural symptoms of ASD. Further clinical research is required.

Summary Review:
The article describes an original clinical protocol in which microbiota transfer was used to ameliorate gastrointestinal (GI) and autism symptoms in pediatric patients. Common occurrence of GI pathology in patients affected by autistic spectrum disorder (ASD), poses a clinical challenge, since there is no standardised specific therapy. In light of recent insights on the importance of microbiota-gut-brain axis in health and disease, microbiota emerges as a salient treatment target in the aforementioned population.
Clinical practice applications:
Fecal microbiota transfer therapy (MTT) applied by the protocol described in the article demonstrates a longer-term effective clinical intervention in pediatric patients suffering from ASD and concomitant GI symptoms. Benefits of the therapy persisted even two months after actual treatment cessation, a highly important feature considering ASD.
Considerations for future research:
This modality could complement current treatments used for ASD-related symptomatology, but requires further validation through additional clinical experiments. The procedure also supports the efforts to focus more research on the role of microbiota in ASD pathophysiology. Further basic and clinical investigations on ASD should include addressing microbiota-gut-brain axis whenever possible, if not always.
Abstract
BACKGROUND Autism spectrum disorders (ASD) are complex neurobiological disorders that impair social interactions and communication and lead to restricted, repetitive, and stereotyped patterns of behavior, interests, and activities. The causes of these disorders remain poorly understood, but gut microbiota, the 1013 bacteria in the human intestines, have been implicated because children with ASD often suffer gastrointestinal (GI) problems that correlate with ASD severity. Several previous studies have reported abnormal gut bacteria in children with ASD. The gut microbiome-ASD connection has been tested in a mouse model of ASD, where the microbiome was mechanistically linked to abnormal metabolites and behavior. Similarly, a study of children with ASD found that oral non-absorbable antibiotic treatment improved GI and ASD symptoms, albeit temporarily. Here, a small open-label clinical trial evaluated the impact of Microbiota Transfer Therapy (MTT) on gut microbiota composition and GI and ASD symptoms of 18 ASD-diagnosed children. RESULTS MTT involved a 2-week antibiotic treatment, a bowel cleanse, and then an extended fecal microbiota transplant (FMT) using a high initial dose followed by daily and lower maintenance doses for 7-8 weeks. The Gastrointestinal Symptom Rating Scale revealed an approximately 80% reduction of GI symptoms at the end of treatment, including significant improvements in symptoms of constipation, diarrhea, indigestion, and abdominal pain. Improvements persisted 8 weeks after treatment. Similarly, clinical assessments showed that behavioral ASD symptoms improved significantly and remained improved 8 weeks after treatment ended. Bacterial and phagedeep sequencing analyses revealed successful partial engraftment of donor microbiota and beneficial changes in the gut environment. Specifically, overall bacterial diversity and the abundance of Bifidobacterium, Prevotella, and Desulfovibrio among other taxa increased following MTT, and these changes persisted after treatment stopped (followed for 8 weeks). CONCLUSIONS This exploratory, extended-duration treatment protocol thus appears to be a promising approach to alter the gut microbiome and virome and improve GI and behavioral symptoms of ASD. Improvements in GI symptoms, ASD symptoms, and the microbiome all persisted for at least 8 weeks after treatment ended, suggesting a long-term impact. TRIAL REGISTRATION This trial was registered on the ClinicalTrials.gov, with the registration number NCT02504554.

Chrononutrition is an emerging field that links the body’s metabolism to its endogenous circadian rhythm. It is now recognised that numerous circadian clocks are found within all major tissues and most cells of the body. This complex network of clocks influences a wide range of biological processes including neuronal, endocrine, metabolic and behavioural function. When there is a disruption in a single circadian clock, whole-organism homeostasis can be impacted, potentially resulting in the development of disease. This review explains the potential mechanisms by which circadian clocks influence biological processes through transgenic animal studies, and how they are being translated to human genetics and metabolomics. The principles of chrononutrition are clinically significant factors that should be considered when managing and treating metabolic disease, as well as maintaining health in the general population.
Abstract
Chrononutrition is an emerging discipline that builds on the intimate relation between endogenous circadian (24-h) rhythms and metabolism. Circadian regulation of metabolic function can be observed from the level of intracellular biochemistry to whole-organism physiology and even postprandial responses. Recent work has elucidated the metabolic roles of circadian clocks in key metabolic tissues, including liver, pancreas, white adipose, and skeletal muscle. For example, tissue-specific clock disruption in a single peripheral organ can cause obesity or disruption of whole-organism glucose homeostasis. This review explains mechanistic insights gained from transgenic animal studies and how these data are being translated into the study of human genetics and physiology. The principles of chrononutrition have already been demonstrated to improve human weight loss and are likely to benefit the health of individuals with metabolic disease, as well as of the general population.

Plain language summary
Alzheimer’s disease (AD) is the third leading cause of death in the USA, with around 5.2 million Americans diagnosed with AD. Effective treatment with medications has yet to be found. A recent multiple therapy programme (originally known as MEND, now called ReCODE) proposed by Professor Bredesen and team, has shown some promising anecdotal results. Identifying sub-types of AD has been proposed as a means to develop targeted protocols for treatment. Recently, 3 sub-types of AD have been described: Type 1 (inflammatory), Type 2 (non-inflammatory or decreasing brain size) and Type 3 (damage to the outer layer of the cerebrum). This report describes 7 patients with Type 3 AD. Type 3 AD is characterised by exposure to specific toxins (usually inhaled) and is often associated with Chronic Inflammatory Response Syndrome (CIRS). The report provides the symptoms, signs and laboratory values representative of Type 3 AD and could be used by Nutrition Practitioners to help with implementation of appropriate nutrition protocols when working with clients with AD.
Abstract
Alzheimer's disease is one of the most significant healthcare problems today, with a dire need for effective treatment. Identifying subtypes of Alzheimer's disease may aid in the development of therapeutics, and recently three different subtypes have been described: type 1 (inflammatory), type 2 (non-inflammatory or atrophic), and type 3 (cortical). Here I report that type 3 Alzheimer's disease is the result of exposure to specific toxins, and is most commonly inhalational (IAD), a phenotypic manifestation of chronic inflammatory response syndrome (CIRS), due to biotoxins such as mycotoxins. The appropriate recognition of IAD as a potentially important pathogenetic condition in patients with cognitive decline offers the opportunity for successful treatment of a large number of patients whose current prognoses, in the absence of accurate diagnosis, are grave.
