Abstract
Adherence is a primary determinant of the effectiveness of any intervention. Exercise is considered essential in the management of spondyloarthritis (SpA); however, the overall adherence to exercise programmes and factors affecting adherence are unknown. The aim of this systematic review was to examine measures of, and factors influencing adherence to, prescribed exercise programmes in people with SpA. A search was performed in August 2018 using five data bases; the Cochrane library, CINAHL, EMBASE, MEDLINE, and Web of Science Collections. Inclusion criteria were: studies with adults (> 18 years) with SpA, with a prescribed exercise intervention or educational programme with the aim of increasing exercise participation. Article quality was independently assessed by two assessors. Extracted descriptive data included: populations, interventions, measures of adherence and factors affecting adherence. Percentage adherence rates to prescribed exercises were calculated if not reported. Nine studies were included with a total of 658 participants, 95% of participants had a diagnosis of ankylosing spondylitis. Interventions and measurement of adherence varied, making comparisons difficult. Rates of adherence ranged from 51.4 to 95%. Single studies identified; adherence improved following educational programmes, and higher disease severity and longer diagnostic delays were associated with higher adherence. Conflicting evidence was found as to whether supervision of exercise improved adherence. Three consecutive studies demonstrated adherence reduced over time. Adherence to prescribed exercise in SpA was poorly reported and predominately for people with AS. The levels of adherence and factors affecting prescribed exercise in SpA remain unclear. Future research should measure adherence across a longer time period and investigate possible factors which may influence adherence.

Abstract
Background Dietary bioactive compounds capable of improving metabolic profiles would be of great value, especially for overweight individuals undergoing a caloric restriction (CR) regimen. Curcumin (Cur), a possible anti-obesity compound, and piperine (Pip), a plausible enhancer of Cur’s bioavailability and efficacy, may be candidate agents for controlling body fat, metabolism and low grade inflammation. Methods 47 eight-week-old male C57BL/6 mice were fed a high fat diet (HFD) for 23 weeks to induce obesity. Then, mice were divided into 5 groups. Group 1 continued on HFD ad libitum. The other 4 groups underwent CR (reduced 10% HFD intake for 10 weeks, 20% for 20 weeks) with Cur, Pip, Cur + Pip or none of these. Percent body fat, plasma inflammatory markers associated with obesity (interferon (IFN)-γ, interleukin (IL)-10, IL-12 p70, IL-1β, IL-6 and KC/GRO), plasma Cur metabolites and liver telomere length were measured. Results Compared to the other groups, obese mice who underwent CR and received Cur + Pip in their diet lost more fat and had significantly lower IL-1β and KC/GRO. Tandem mass spectrometry analysis of plasma from obese mice under CR showed no difference in Cur metabolite levels between groups supplemented with Cur alone or combined with Pip. However, plasma IL-1β levels were inversely correlated with curcumin glucuronide. Minor modulation of telomere length were observed. Conclusions It is plausible that supplementing the high fat diet of CR mice with Cur + Pip may increase loss of body fat and suppresses HFD induced inflammation. Combination of Cur and Pip has potential to enhance CR effects for the prevention of metabolic syndrome.

Abstract
Aim The aim of this study was to assess skin cancer awareness and identify the UV protective measures used by golfers within the Munster region of Ireland. Methods Subjects were recruited from throughout the Munster region at a regional competition, and at three other local golf clubs and "pro" shops. Participants filled out a short anonymous validated questionnaire when collecting their score cards7. Results One hundred and sixty-three golfers completed the questionnaire with a mean age of 65.6 years. 137 (84%) were male and 26 (16%) were female. We noted a high incidence of both non-melanoma and melanoma skin cancer in our subjects. Sixteen (9.8%) had a previous history of skin cancer, with 8 melanomas and 8 non-melanoma skin cancers. A high percentage, 85%, of the golfers surveyed were compliant with SPF use. However many were using too low a SPF, 63 (44%) were using a SPF less than 30. Knowledge of risk of skin cancer is better amongst the golfers surveyed when compared to the general population. Most respondents (N = 96 (59%)) were aware that melanoma can lead to death if left untreated and 114 (70%) recognized that melanoma can be cured if treated early. Conclusion Golfers may benefit from targeted education emphasizing the importance of higher SPF use. Other interventions that may benefit this population would include availability of sunscreens and educational literature in 'pro' shops at golf courses.

Abstract
BACKGROUND Impaired mobility is a cardinal feature of multiple sclerosis (MS) and is rated by people with MS as their highest priority. By the secondary progressive phase, balance, mobility and physical activity levels are significantly compromised; an estimated 70% of people with secondary progressive MS fall regularly. Our ongoing research has systematically developed 'Balance Right in MS' (BRiMS), an innovative, manualised 13-week guided self-management programme tailored to the needs of people with MS, designed to improve safe mobility and minimise falls. Our eventual aim is to assess the clinical and cost effectiveness of BRiMS in people with secondary progressive MS by undertaking an appropriately statistically powered, multi-centre, assessor-blinded definitive, randomised controlled trial. This feasibility study will assess the acceptability of the intervention and test the achievability of running such a definitive trial. METHODS/DESIGN This is a pragmatic multi-centre feasibility randomised controlled trial with blinded outcome assessment. Sixty ambulant people with secondary progressive MS who self-report two or more falls in the previous 6 months will be randomly allocated (1:1) to either the BRiMS programme plus usual care or to usual care alone. All participants will be assessed at baseline and followed up at 15 weeks and 27 weeks post-randomisation. The outcomes of this feasibility trial include:Feasibility outcomes, including trial recruitment, retention and completionAssessment of the proposed outcome measures for the anticipated definitive trial (including measures of walking, quality of life, falls, balance and activity level)Measures of adherence to the BRiMS programmeData to inform the economic evaluation in a future trialProcess evaluation (assessment of treatment fidelity and qualitative evaluation of participant and treating therapist experience). DISCUSSION The BRiMS intervention aims to address a key concern for MS service users and providers. However, there are several uncertainties which need to be addressed prior to progressing to a full-scale trial, including acceptability of the BRiMS intervention and practicality of the trial procedures. This feasibility trial will provide important insights to resolve these uncertainties and will enable a protocol to be finalised for use in the definitive trial. TRIAL REGISTRATION ISRCTN13587999.

Abstract
Here we describe an in vitro primary culture system for Caenorhabditis elegans germline stem cells. This culture system was used to identify a bacterial folate as a positive regulator of germ cell proliferation. Folates are a family of B-complex vitamins that function in one-carbon metabolism to allow the de novo synthesis of amino acids and nucleosides. We show that germ cell proliferation is stimulated by the folate 10-formyl-tetrahydrofolate-Glun both in vitro and in animals. Other folates that can act as vitamins to rescue folate deficiency lack this germ cell stimulatory activity. The bacterial folate precursor dihydropteroate also promotes germ cell proliferation in vitro and in vivo, despite its inability to promote one-carbon metabolism. The folate receptor homolog FOLR-1 is required for the stimulation of germ cells by 10-formyl-tetrahydrofolate-Glun and dihydropteroate. This work defines a folate and folate-related compound as exogenous signals to modulate germ cell proliferation.

Abstract
Walking is the primary form of physical activity performed by people with Multiple Sclerosis (MS), therefore it is important to ensure the validity of tools employed to measure walking activity. The aim of this study was to assess the criterion validity of the activPAL3 activity monitor during overground walking in people with MS. Validity of the activPAL3 accelerometer was compared to video observation in 20 people moderately affected by MS. Participants walked 20-30m twice along a straight quiet corridor at a comfortable speed. Inter-rater reliability of video observations was excellent (all intraclass correlations >0.99). The mean difference (activPAL3- mean of raters) was -4.70±9.09, -4.55s±10.76 and 1.11s±1.11 for steps taken, walking duration and upright duration respectively. These differences represented 8.7%, 10.0% and 1.8% of the mean for each measure respectively. The activPAL3 tended to underestimate steps taken and walking duration in those who walked at cadences of ≤38 steps/min by 60% and 47%, respectively. The activPAL3 is valid for measuring walking activity in people moderately affected by MS. It is accurate for upright duration regardless of cadence. In participants with slow walking cadences, outcomes of steps taken and walking duration should be interpreted with caution.

Abstract
Arsenic exposure may contribute to disease risk in humans through alterations in the epigenome. Previous studies reported that arsenic exposure is associated with changes in plasma histone concentrations. Posttranslational histone modifications have been found to differ between the brain tissue of human embryos with neural tube defects and that of controls. Our objectives were to investigate the relationships between plasma histone 3 levels, history of having an infant with myelomeningocele, biomarkers of arsenic exposure, and maternal folate deficiency. These studies took place in Bangladesh, a country with high environmental arsenic exposure through contaminated drinking water. We performed ELISA assays to investigate plasma concentration of total histone 3 (H3) and the histone modification H3K27me3. The plasma samples were collected from 85 adult women as part of a case-control study of arsenic and myelomeningocele risk in Bangladesh. We found significant associations between plasma %H3K27me3 levels and risk of myelomeningocele (P<0.05). Mothers with higher %H3K27me3 in their plasma had lower risk of having an infant with myelomeningocele (odds ratio: 0.91, 95% confidence interval: 0.84, 0.98). We also found that arsenic exposure, as estimated by arsenic concentration in toenails, was associated with lower total H3 concentrations in plasma, but only among women with folate deficiency (β = -9.99, standard error = 3.91, P=0.02). Our results suggest that %H3K27me3 in maternal plasma differs between mothers of infants with myelomeningocele and mothers of infants without myelomeningocele, and may be a marker for myelomeningocele risk. Women with folate deficiency may be more susceptible to the epigenetic effects of environmental arsenic exposure.

Abstract
Abstract
Abl interactor 1 (Abi1) is a key component of WAVE regulatory complex (WRC) that regulates actin cytoskeleton reorganization, membrane receptor signaling, and intracellular trafficking. Recent in vitro and in vivo studies as well as the studies of human patient samples suggest that Abi1 may play an important role in breast cancer (BC) metastasis. To determine if Abi1 is deregulated in metastatic breast cancer cells, we compared the expression of Abi1 in a panel of human breast cancer cell lines exhibiting distinct metastatic properties. In comparison with low-metastatic ER+/PR+ BC lines MCF-7 and T47D and a non-transforming mammary epithelial cell line MCF-10A, two ER-BC lines CN34 and MDA 231 and their sublines selected by high metastatic potential to bone (231Bo), brain (231Br and CN34Br), and lung (231LM2) show significantly reduced Abi1 protein levels, with greater reduction found in highly metastatic sublines. It is unlikely that the down-regulation of Abi1 expression in these metastatic BC cells occurs at mRNA level, because RT-PCR analysis shows no significant difference in Abi1 mRNA levels among the cells analyzed. Interestingly, despite a reduction in protein level, the tyrosine phosphorylation of Abi1 was increased in CN34, MDA231, and their metastatic sublines compared to low-metastatic BC cells. The tyrosine phosphorylation of Abi1 is stimulated by epidermal growth factor (EGF) in these cells and Abi1 is recruited to EGF receptor (EGFR) upon EGF stimulation. The deregulation of Abi1 in metastatic BC cells is mediated by Abl tyrosine kinases, as the inhibition of Abl family kinases by imatinib not only attenuates EGF-stimulated Abi1 tyrosine phosphorylation but also rescue the down-regulation of Abi1 protein in metastatic BC cells.
These findings are consistent with a role of the EGFR-Abl-Abi1 signaling in BC metastasis. The studies suggest that this pathway may serve as a biomarker for diagnosis and/or prognosis of metastatic breast cancer. We have identified the tyrosine 213 in Abi1 as a major phosphorylation site stimulated by Abl kinases and have generated a unique conditional Abi1 depletion/re-expression system to dissect how the deregulation of the Abi1 signaling contributes to BC metastasis.

Abstract
BACKGROUND AND PURPOSE The introduction of liquid embolic agents has revolutionized endovascular approach to cranial vascular malformations. The aim of the study was to retrospectively assess the efficacy and safety of Precipitating Hydrophobic Injectable Liquid (PHIL), a new nonadhesive liquid embolic agent, in the treatment of patients with cranial dural arteriovenous fistulas. The primary end point was the rate of complete occlusion of dural arteriovenous fistulas. Secondary end points included the incidence of adverse events and clinical status at 3-month follow-up. MATERIALS AND METHODS This was a retrospective multicenter study. Twenty-six consecutive patients with dural arteriovenous fistulas (de novo or previously treated) treated by injection of PHIL only or with PHIL in combination with other embolization products (such as Onyx or detachable coils) were included in the study. Recruitment started in August 2014 and ended in September 2015. RESULTS Twenty-two (85%) patients were treated with PHIL only, with 3 patients treated with both PHIL and Onyx, and 1, with both PHIL and coils. Immediate complete angiographic occlusion was achieved in 20 (77%) patients. Of the 6 patients with residual fistulas, 3 were retreated with PHIL and 1 achieved angiographic cure. An adverse event was seen in 1 patient who developed worsening of preexisting ataxia due to acute thrombosis of the draining vein. CONCLUSIONS PHIL appears to be safe and effective for endovascular treatment of cranial dural arteriovenous fistulas. Short-term angiographic and clinical results are comparable with those of Onyx, with the added advantage of easier preparation and improved homogeneous cast visualization. The use of iodine as a radio-opacifier also produces considerably less artifacts on CT compared with tantalum-based embolic materials.

Abstract
BACKGROUND The 776C→G polymorphism of the vitamin B-12 transport protein transcobalamin gene (TCN2) (rs1801198; Pro259Arg) is associated with a lower holotranscobalamin concentration in plasma. This effect may reduce the availability of vitamin B-12 to tissues even when vitamin B-12 intake is adequate. Clinical outcomes associated with vitamin B-12 insufficiency could potentially be worsened by high folate intake. OBJECTIVE We determined the association of the TCN2 776C→G polymorphism and folate intake with peripheral neuropathy in elders with normal plasma concentrations of vitamin B-12. DESIGN Participants in this cross-sectional study (n = 171) were from a cohort of community-based, home-bound elderly individuals aged ≥60 y who underwent an evaluation by physicians including an assessment for peripheral neuropathy. Participants were administered food-frequency and general health status questionnaires, anthropometric measurements were taken, and a fasting blood sample from each subject was collected. RESULTS Odds of neuropathy were 3-fold higher for GG genotypes than for CC genotypes (OR: 3.33; 95% CI: 1.15, 9.64). When folate intake was >2 times the Recommended Dietary Allowance (800 μg), GG genotypes had 6.9-fold higher odds of neuropathy than CC genotypes (OR: 6.9; 95% CI: 1.31, 36.36). There was no difference between the genotypes in the odds of peripheral neuropathy when folate intake was ≤800 μg (OR: 1.5; 95% CI: 0.18, 12.33). CONCLUSION The TCN2 776C→G polymorphism is associated with increased odds of peripheral neuropathy in the elderly, even with a normal vitamin B-12 status, especially if their folate intake is >2 times the Recommended Dietary Allowance.

Abstract
Current epidemiological evidence suggests that an imbalance of high folate status and low vitamin B12 status is associated with negative health outcomes in older adults and children. Such an imbalance during pregnancy also predisposes women to diabetes and their offspring to insulin resistance and adiposity and low birthweight. In older adults, vitamin B12 status can remain low despite adequate intake due to age-related decline in vitamin B12 absorption. Pregnant women are exposed to folic acid at varying doses depending on the prenatal care prescribed in different countries. This review summarizes the current knowledge on the interaction between folate and vitamin B12 and the associated health outcomes.

Abstract
STUDY DESIGN A pilot randomised controlled trial. OBJECTIVES The aims of this study were to evaluate the effectiveness and participant satisfaction of web-based physiotherapy in people with spinal cord injury (SCI). SETTING Community patients of a national spinal injury unit in a university teaching hospital, Scotland, UK. METHODS Twenty-four participants were recruited and randomised to receive 8 weeks of web-based physiotherapy (intervention), twice per week, or usual care (control). Individual exercise programmes were prescribed based on participants' abilities. The intervention was delivered via a website (www.webbasedphysio.com) and monitored and progressed remotely by the physiotherapist. RESULTS Participants logged on to the website an average of 1.4±0.8 times per week. Between-group differences, although not significant, were more pronounced for the 6-min walk test. Participants were positive about using web-based physiotherapy and stated that they would be happy to use it again and would recommend it to others. Overall, it was rated as either good or excellent. CONCLUSIONS Web-based physiotherapy was feasible and acceptable for people with SCI. Participants achieved good compliance with the intervention and rated the programme highly and beneficial for health and well-being at various states after injury. The results of this study warrant further work with a more homogeneous sample. SPONSORSHIP This study was funded by the Queen Elizabeth National Spinal Injuries Unit, Glasgow, UK.

Abstract
PURPOSE Quality of life in women receiving adjuvant endocrine therapy for breast cancer (BC) may be impaired by hot flushes and night sweats. The cool pad pillow topper (CPPT) is a commercial product, promoted to improve quality of sleep disrupted by hot flushes. This study aimed to identify if the CPPT reduces severity of sleep disturbance by minimising effects of hot flushes. METHODS This randomised phase II trial, recruited women with BC, on adjuvant endocrine therapy, experiencing hot flushes and insomnia. Participants were randomised (stratified by baseline sleep efficiency score (SES) and menopausal status) to the intervention arm (CPPT + standard care) or control arm (standard care). Participants completed Hospital Anxiety and Depression Scale and Functional Assessment of Cancer Therapy-Breast (FACT-B) questionnaires and fortnightly sleep/hot flush diaries (where responses were averaged over 2-week periods). The primary endpoint was change in average SES from -2 to 0 weeks to 2 to 4 weeks. RESULTS Seventy-four pre- (68.9 %) and post-menopausal (31.1 %) women were recruited. Median age was 49.5 years. Endocrine therapies included tamoxifen (93.2 %). Median SES at weeks 2 to 4 improved in both arms but the increase on the intervention arm was almost twice that on the control arm (p = 0.024). There were significantly greater reductions in hot flushes and HADS depression in the intervention arm (p = 0.09 and p = 0.036, respectively). There were no significant differences in FACT-B or HADS anxiety. CONCLUSION This study supports the use of the CPPT as an aid to reduce sleep disturbance and the frequency/severity of hot flushes.

Evidence from a Randomized Trial That Exposure to Supplemental Folic Acid at Recommended Levels during Pregnancy Does Not Lead to Increased Unmetabolized Folic Acid Concentrations in Maternal or Cord Blood. J Nutr 2016; 146:494-500.

Abstract
BACKGROUND Exposure to higher intakes of folic acid (FA) from fortified foods and supplements, although largely considered beneficial, is associated with unmetabolized FA in the circulation, which has raised some health concerns. OBJECTIVE The effect of supplemental FA at a dose of 400 μg/d during pregnancy on unmetabolized FA concentrations in maternal plasma and newborn cord blood plasma was investigated. METHODS A new analysis was performed of blood samples from participants in a randomized trial in pregnancy. Women aged 18-35 y, who had taken 400 μg FA/d as recommended in the first trimester, were recruited at the start of trimester 2 and randomly allocated to receive either 400 μg FA/d (n = 59) or a placebo (n = 67) throughout the second and third trimesters until delivery. Unmetabolized FA concentrations in maternal and cord blood samples were measured by LC-tandem MS analysis. RESULTS In response to the intervention from gestational week 14 through delivery, a higher proportion of women in the FA compared with the placebo group had detectable FA (≥0.27 nmol/L) in plasma, but the difference in concentrations was not statistically significant (mean ± SD: 0.44 ± 0.80 compared with 0.13 ± 0.49 nmol/L, P = 0.38). FA treatment throughout pregnancy resulted in higher cord blood plasma total folate (50.6 ± 20.1 compared with 34.5 ± 14.4 nmol/L; P = 0.004) and 5-methyltetrahydrofolate (50.4 ± 20.3 compared with 34.5 ± 14.4 nmol/L; P = 0.005) concentrations, but FA was detected only in 8 of 53 available cord blood samples, and the proportion of samples with detectable FA concentrations was similar in FA-treated and placebo groups. CONCLUSIONS Plasma concentrations of unmetabolized FA arising from supplemental FA at a dose of 400 μg/d, in addition to FA from fortified foods, were low or undetectable in mothers and newborns. The benefits for mothers and offspring of continuing FA supplementation beyond the first trimester of pregnancy can be achieved without posing any risk of increasing unmetabolized circulating FA, even in those already exposed to FA from fortified foods.

Abstract
Higher folate has been associated with a reduced colorectal cancer (CRC) risk, but excessive folate may promote tumor progression. The role of unmetabolized folic acid (UFA) from high folic acid consumption in carcinogenesis is largely unexplored. We evaluated prediagnostic plasma levels of UFA in relation to CRC risk in nested case-control studies (618 CRC case patients and 1207 matched control) with blood samples collected prior to folic acid fortification. UFA was detected in 21.4% of control UFA levels were not associated with CRC risk. Compared with undetectable levels, the multivariable relative risks (RRs) of CRC were 1.03 (95% confidence interval [CI] = 0.73 to 1.46) for less than 0.5 nmol/L and 1.12 (95% CI = 0.81 to 1.55) for 0.5 nmol/L or more (Ptrend = .32). A positive association between UFA levels and CRC risk was observed among men (RR = 1.57, 95% CI = 0.99 to 2.49 for ≥0.5 nmol/L vs undetectable, Pinteraction = .04), and a positive association was also observed among those with the methylene-tetrahydrofolate reductase (MTHFR) CT/TT genotype (RR = 2.20, 95% CI = 1.22 to 3.94 for ≥0.5 nmol/L vs undetectable, Pinteraction=0.02). In conclusion, prediagnostic plasma levels of UFA from the prefortification period were not associated with risk of CRC.
