Abstract
BACKGROUND Adolescents with disabilities have fewer opportunities to participate in community-based fitness programmes. The purpose of this study was to examine the impact of a school-based running programme at a local middle school in Lebanon, Pennsylvania, on fitness and quality of life (QoL) in children with physical and cognitive disabilities in a life-skills classroom. METHODS Nineteen adolescents with diagnosed disabilities including intellectual disability (ID), autism spectrum disorder and Down syndrome were recruited from three life-skills classrooms to participate in a school-based running programme. The programme was designed to be implemented two times/week for 6 weeks by classroom teachers/aides. Physical therapy faculty and students developed the programme and assisted with implementation. Each session lasted 30 min, consisting of a warm-up and cooldown, relay races, games and timed runs. Pre- and post-test measures included physiological cost index (PCI) and Paediatric Quality of Life Inventory™ (PedsQL™). Pre- and post-test data were compared using Wilcoxon signed rank tests. Each week participants also completed a training log to reflect on the activity for the day. RESULTS Participants demonstrated significant improvements in PCI (P = 0.028) and the PedsQL™ (P = 0.008) following the running programme. CONCLUSIONS Results of this study suggest that participation in a 6-week school-based running programme may improve fitness and QoL in adolescents with disabilities.

Abstract
This study compares the effectiveness of pharmacological treatments to develop guidelines for the management of acute pain after tooth extraction. We searched Medline, EMBASE, CENTRAL, and US Clinical Trials registry on November 21, 2020. We included randomized clinical trials (RCTs) of participants undergoing dental extractions comparing 10 interventions, including acetaminophen, nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and combinations to placebo. After duplicate screening and data abstraction, we conducted a frequentist network meta-analysis for each outcome at 6 h (i.e., pain relief, total pain relief [TOTPAR], summed pain intensity difference [SPID], global efficacy rating, rescue analgesia, and adverse effects). We assessed the risk of bias using a modified Cochrane RoB 2.0 tool and the certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation approach. We implemented the analyses in RStudio version 3.5.3 and classified interventions from most to least beneficial or harmful. We included 82 RCTs. Fifty-six RCTs enrolling 9,095 participants found moderate- and high-certainty evidence that ibuprofen 200 to 400 mg plus acetaminophen 500 to 1,000 mg (mean difference compared to placebo [MDp], 1.68; 95% confidence interval [CI], 1.06-2.31), acetaminophen 650 mg plus oxycodone 10 mg (MDp, 1.19; 95% CI, 0.85-1.54), ibuprofen 400 mg (MDp, 1.31; 95% CI, 1.17-1.45), and naproxen 400-440 mg (MDp, 1.44; 95% CI, 1.07-1.80) were most effective for pain relief on a 0 to 4 scale. Oxycodone 5 mg, codeine 60 mg, and tramadol 37.5 mg plus acetaminophen 325 mg were no better than placebo. The results for TOTPAR, SPID, global efficacy rating, and rescue analgesia were similar. Based on low- and very low-certainty evidence, most interventions were classified as no more harmful than placebo for most adverse effects. Based on moderate- and high-certainty evidence, NSAIDs with or without acetaminophen result in better pain-related outcomes than opioids with or without acetaminophen (except acetaminophen 650 mg plus oxycodone 10 mg) or placebo.

Abstract
Firefighting is a high-risk occupation that accounts for vulnerability to a range of mental health problems and addictive behaviours. However, no research has addressed whether this vulnerability extends to gambling problems, and the aim of this study was thus to provide new data on frequency and implications of such problems in this occupational context. The sample consisted of n = 566 career and retained firefighters who participated in a cross-sectional survey of an Australian metropolitan fire service. The Problem Gambling Severity Index (PGSI) was used to operationalise both clinically significant levels of problem gambling (PGSI ≥ 5), and 'at-risk' gambling (PGSI 1-4); alongside measures of major depression (PHQ-9), anxiety (GAD-7), Posttraumatic Stress Disorder (PCL-5) and alcohol problems (AUDIT), as well as other addictive behaviours, wellbeing and psychosocial issues. Results indicated 12.3% of firefighters that reported any gambling problems across a continuum of severity (PGSI ≥ 1), including 2.3% that were problems gamblers, and 10.0% reporting at-risk gambling. The weighted prevalence of problem gambling was comparable to other significant mental health conditions including depression and PTSD, while the rate of any gambling problems was high relative to other addictive behaviours. Gambling problems were associated with poor mental health and wellbeing, but not psychosocial indicators (e.g., financial difficulties). The findings suggest that gambling problems across a spectrum of severity may be significant yet hidden issues among emergency service workers, and thus require increased recognition and responses at the organisational level.

Abstract
BACKGROUND AND OBJECTIVES Sex hormone concentrations and telomere length are age related responses of human body, while whether there is a direct relation between sex hormone and telomere length is uncertain. Therefore, we used the data of National Health and Nutrition Examination Survey (NHANES) to quantify their direct association. RESEARCH DESIGN AND METHODS A total of 710 women aged 35-60 years and 539 men aged 20-85 years were included from two cycles of the NHANES (1999-2002). Telomere length relative to standard reference DNA (T/S ratio) was measured using quantitative polymerase chain reaction method. Seven hormones in serum (5 in men and 2 in women) were assayed. Logistic regressions were used to calculate the odds ratios to evaluate the telomere length-sex hormones association. RESULTS Men with vigorous physical activity (71.1%) and without history of cardiovascular diseases, diabetes, and lipid-lowering drugs using tended to have a longer telomere length (all P-values < 0.05); while women with longer sedentary time, smaller pregnant or live birth, and with older ages of firth/last birth were likely with longer telomere length (all P-values < 0.05). After adjusted for potential confounders, only anti-Mullerian hormone was positively and stably associated with short leukocytes telomere length in men (OR: 1.098; 95% CI: 1.034, 1.165). We did not detect any significant association of short telomere length with sex hormones in men and women. Discussion and Implications: Serum anti-Mullerian hormone in men was positively and stably associated with telomere length. More large-scaled and well-designed prospective studies are warranted to reconfirm our conclusions.

Abstract
OBJECTIVE To pilot investigation of muscle fiber diameter (MFD) on medial and lateral sides of the cleft in 18 infants with cleft lip with or without cleft palate (CL/P) using image processing. MATERIAL AND METHODS Formalin-fixed paraffin-embedded (FFPE) tissue samples from the medial and lateral sides of the cleft were analyzed for MFD using an image-processing program (ImageJ). For within-case comparison, a paired Student's t test was performed. For comparisons between classes, an unpaired t test was used. RESULTS Image processing enabled rapid measurement of MFD with majority of fibers showing diameter between 6 and 11 μm. There was no significant difference in mean MFD between the medial and lateral sides, or between CL and CLP. However, we found a significant difference on the medial side (p = .032) between males and females. CONCLUSION The image processing on FFPE tissues resulted in easy quantification of MFD with finding of a smaller MFD on the medial side in males suggesting possible differences in orbicularis oris (OO) muscle between the two sexes in CL that warrants replication using larger number of cases. Moreover, this finding can aid subclinical phenotyping and potentially in the restoration of the anatomy and function of the upper lip.

Abstract
OBJECTIVE To compare psychosocial outcomes (follow-up related worries and satisfaction with follow-up related information and support) over 30 months of two alternative management policies for women with low-grade abnormal cervical cytology. METHODS Women aged 20-59 years with low-grade cytological abnormalities detected in the National Health Service Cervical Screening Programme were randomised to cytological surveillance or initial colposcopy. A total of 3399 women who completed psychosocial questionnaires at recruitment were invited to complete questionnaires at 12, 18, 24 and 30 months. Linear mixed models were used to investigate differences between arms in the two psychosocial outcomes. Each outcome had a maximum score of 100, and higher scores represented higher psychosocial morbidity. RESULTS On average, over 30 months, women randomised to colposcopy scored 2.5 points (95%CI -3.6 to -1.3) lower for follow-up related worries than women randomised to cytological surveillance. Women in the colposcopy arm also scored significantly lower for follow-up related satisfaction with information and support (-2.4; -3.3 to -1.4) over 30 months. For both outcomes, the average difference between arms was greatest at 12th- and 18th-month time points. These differences remained when the analysis was stratified by post-school education. CONCLUSIONS Women with low-grade cytology, irrespective of their management, have substantial initial psychosocial morbidity that reduces over time. Implementation of newer screening strategies, which include surveillance, such as primary HPV screening, need to consider the information and support provided to women. © 2016 The Authors.

Abstract
A new genus and species in the family Parabathynellidae Noodt, 1965, Lockyerenella danschmidti, gen. et sp. nov., is described from Queensland, Australia. The species displays several distinctive character states within the Parabathynellidae, and a unique combination of character states. Interestingly, L. danschmidti is the only known species of Parabathynellidae in Australia (and in the world) to possess a long and robust seta on the last segment of the antenna, which is present in both males and females. The new genus is morphologically distinct from the known genera, but is more similar to Queensland species of Notobathynella Schminke, 1973 and Arkaroolabathynella Abrams & King, 2013 from South Australia, than to species from other areas of the continent. This is the first work to couple genetics to the morphological description of a stygofauna species in Queensland. Phylogenetic relationships between L. danschmidti and related genera from elsewhere on the continent were evaluated through the analysis of combined mitochondrial and nuclear DNA sequence data. This analysis revealed at least one new genus within the Parabathynellidae, confirming our morphological hypothesis.

Abstract
BACKGROUND The melanocortin-1-receptor (MC1R) gene regulates human pigmentation and is highly polymorphic in populations of European origins. The aims of this study were to evaluate the association between MC1R variants and the risk of non-melanoma skin cancer (NMSC), and to investigate whether risk estimates differed by phenotypic characteristics. METHODS Data on 3527 NMSC cases and 9391 controls were gathered through the M-SKIP Project, an international pooled-analysis on MC1R, skin cancer and phenotypic characteristics. We calculated summary odds ratios (SOR) with random-effect models, and performed stratified analyses. RESULTS Subjects carrying at least one MC1R variant had an increased risk of NMSC overall, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC): SOR (95%CI) were 1.48 (1.24-1.76), 1.39 (1.15-1.69) and 1.61 (1.35-1.91), respectively. All of the investigated variants showed positive associations with NMSC, with consistent significant results obtained for V60L, D84E, V92M, R151C, R160W, R163Q and D294H: SOR (95%CI) ranged from 1.42 (1.19-1.70) for V60L to 2.66 (1.06-6.65) for D84E variant. In stratified analysis, there was no consistent pattern of association between MC1R and NMSC by skin type, but we consistently observed higher SORs for subjects without red hair. CONCLUSIONS Our pooled-analysis highlighted a role of MC1R variants in NMSC development and suggested an effect modification by red hair colour phenotype.

Abstract
OBJECTIVES To determine the rate of cervical intraepithelial neoplasia grade 2 (CIN2+) in women with low grade cervical cytology and a normal colposcopy examination over 3 years of follow-up. DESIGN Cohort study within a randomised controlled trial. SETTING NHS Cervical Screening Programmes in Grampian, Tayside and Nottingham. POPULATION Eight hundred and eighty-four women aged 20-59 years with borderline nuclear abnormalities (BNA) or mild dyskaryosis with a normal and adequate colposcopy examination. METHODS Samples at baseline were tested for 14 high-risk (Hr) types using GP5+6+ methodology and for HPV 16 and 18 using type-specific primers. Women were followed up post-colposcopy by cervical cytology at 6-month intervals in primary care. After 3 years, women were invited for an exit colposcopy examination and underwent LLETZ if any colposcopic abnormality was identified. MAIN OUTCOME MEASURES Absolute and relative risks of CIN2+ during follow-up and/or at exit colposcopy. RESULTS The median age was 36 years. The absolute risk of developing CIN2+ within 3 years was 1.86 per 100 woman years and for CIN3+, 0.64 per 100 woman years. One microinvasive cancer was identified. The relative risk (RR) was highest for women with initial mild dyskaryosis who were HrHPV-positive (RR 5.86, 95% confidence interval 2.53-13.56) compared with women with BNA who were HrHPV-negative. CONCLUSION For women with low grade cervical cytology, the risk of a high grade CIN within 3 years of a normal colposcopy examination is low. Women can be reassured that, even with a positive HPV test, the risk of developing CIN2 or worse is sufficiently low to return to the routine 3-year recall.

Abstract
Including low penetrance genomic variants in population-based screening might enable personalization of screening intensity and follow up. The application of genomics in this way requires formal evaluation. Even if clinically beneficial, uptake would still depend on the attitudes of target populations. We developed a deliberative workshop on two hypothetical applications (in colorectal cancer and newborn screening) in which we applied stepped, neutrally-framed, information sets. Data were collected using nonparticipant observation, free-text comments by individual participants, and a structured survey. Qualitative data were transcribed and analyzed using thematic content analysis. Eight workshops were conducted with 170 individuals (120 colorectal cancer screening and 50 newborn screening for type 1 diabetes). The use of information sets promoted informed deliberation. In both contexts, attitudes appeared to be heavily informed by assessments of the likely validity of the test results and its personal and health care utility. Perceived benefits included the potential for early intervention, prevention, and closer monitoring while concerns related to costs, education needs regarding the probabilistic nature of risk, the potential for worry, and control of access to personal genomic information. Differences between the colorectal cancer and newborn screening groups appeared to reflect different assessments of potential personal utility, particularly regarding prevention.

Abstract
OBJECTIVE Family history (FH) provides insights into the effects of shared genomic susceptibilities, environments and behaviors, making it a potentially valuable risk assessment tool for chronic diseases. We assessed whether coronary heart disease (CHD) risk assessment is improved when FH information is added to other clinical information recommended in guidelines. METHODS We applied logistic regression analyses to cross-sectional data originally obtained from a UK study of women who delivered a live-born infant between 1951 and 1970. We developed 3 models: Model 1 included only the covariates in a guideline applicable to the population, Model 2 added FH to Model 1, and Model 3 included a fuller range of risk factors. For each model, its ability to discriminate between study subjects with and those without CHD was evaluated and its impact on risk classification examined using the net reclassification index. RESULTS FH was an independent risk factor for CHD (odds ratio = 1.7, 95% confidence interval = 1.26-2.47) and improved discrimination beyond guideline-defined clinical factors (p < 0.0006). However, the difference in the area under the curve of 2.8% and the extent of patient reclassification resulting from the inclusion of FH were small (p = 0.11). CONCLUSION While FH were a significant independent risk factor for CHD, it added little to risk factors typically included in guidelines.

Abstract
We have utilized a series of glioma cell lines to study the effects of ionizing radiation on the regulation of proteins that contribute to cell cycle progression. While no alterations of cyclin E or cdk4 were detected, a high percentage of glioma cell lines exhibited constitutive overexpression of cdk2 protein and aberrant patterns of cyclin D1 protein. The fraction of glioma cells expressing cdk2 was similar to that observed in normal astrocytes, but individual glioma cells overexpressed cdk2. In response to ionizing radiation, both cyclin D1 and cdk2 accumulated in control cells but not in gliomas with overexpressed cdk2 or aberrant cyclin D1. These novel findings provide the first evidence of altered cyclin-cdk regulation in gliomas in response to ionizing radiation.

Abstract
The apparent contradiction between the absence of an effect of 325 mg aspirin taken every other day on the incidence of colorectal cancer in a randomized controlled trial and the consistent inverse association between aspirin and other non-steroidal anti-inflammatory drugs and colorectal cancer and polyps in observational epidemiologic studies is discussed. It is noted that the randomized trial of aspirin may have limited external validity. Information is needed on the effects of timing, duration and quantity of dose, and the effects of other non-steroidal anti-inflammatory drugs, particularly in view of the complexity of balancing established and potential risks and benefits of a possible public health intervention. Mechanisms whereby these drugs could influence the development of colorectal neoplasia are considered.

Abstract
The prognosis of biliary tract cancer is still poor. Although a number of clinical studies have suggested a role for radiation therapy in advanced biliary tract cancer, its value remains controversial. Moreover, the intrinsic radiosensitivity of bile duct cancer cell lines has not been described, and the molecular basis for the response of these tumors to ionizing radiation is poorly understood. The present study was designed to examine the intrinsic radiation sensitivity of human biliary tract cancer cells and its relationship to p53 status. Radiation response expressed by the parameters n, D-0, D-10, alpha, beta, (D) over bar (mean inactivation dose), and SF, of seven cell lines derived from gallbladder and bile duct cancers was determined. The results suggest that biliary tract cancer cell lines as a group are relatively radioresistant. The mean X-ray survival parameters for these seven cancer cell lines were D-0=2.13+/-0.29 Gy, D-10=5.73+/-0.59 Gy, (D) over bar=2.76+/-0.25 Gy, alpha=0.25+/-0.03, and SF2=0.54+/-0.05. One of the seven lines was more radiosensitive than the others (D-0=0.77+/-0.02 Gy, D-10=2.95+/-0.06 Gy, (D) over bar=1.57 Gy, alpha=0.35, SF2=0.35+/-0.03). Five of six lines examined expressed mutant p53 including the radiosensitive line; one radioresistant line expressed wild-type p53. Thus, although loss of wild-type p53 expression occurred frequently in these biliary cancer cell lines, radiosensitivity did not correlate with p53 status. In view of the intrinsic radioresistance of this type of tumor cell coupled with the poor tolerance of surrounding normal tissues, maximal surgical debulking and intraoperative radiation therapy may contribute to increased local control over resection and/or conventional fractionated radiotherapy.

Abstract
The aim of this study was to investigate what affect profiling dialysate sodium and ultrafiltration rate had on cardiovascular stability during haemodialysis, and if there was any effect on patients' fluid balance, thirst, serum sodium levels, blood pressure, or comfort and tolerance. The past decade has seen major advances in haemodialysis machine technology. Parallel developments have included profiling dialysate sodium levels and fluid removal during dialysis. However, some dialysis centres do not use profiling due to fears of long-term detrimental effects, especially with regard to hypertension and fluid control. Within my own workplace, approximately 30% of haemodialysis treatments utilise either sodium or ultrafiltration profiling, or a combination of both. Anecdotally, we have seen an increase in cardiovascular stability and haemodialysis tolerance. The aim of this study was to identify the effects of profiling haemodialysis, to ensure that the treatment we offer patients is safe and effective.

Abstract
Family health history (FHH) has potential value in many health care settings. This review discusses the potential uses of FHH information in primary care and the need for tools to be designed accordingly. We developed a framework in which the attributes of FHH tools are mapped against these different purposes. It contains 7 attributes mapped against 5 purposes. In considering different FHH tool purposes, it is apparent that different attributes become more or less important, and that tools for different purposes require different implementation and evaluation strategies. The context in which a tool is used is also relevant to its effectiveness. For FHH tools, it is unlikely that 'one size fits all', although appreciation of different purposes, users and contexts should facilitate the development of different applications from single FHH platforms.

Abstract
The birth prevalence of orofacial clefts, one of the most common congenital anomalies, is approximately one in 700 live births, but varies with geography, ethnicity, and socio-economic status. There is a variation in infant mortality and access to care both between and within countries, so some clefts remain unrepaired into adulthood. Quality of care also varies, and even among repaired clefts there is residual deformity and morbidity that significantly affects some children. The two major issues in attempts to address these inequalities are (a) etiology/possibilities for prevention and (b) management and quality of care. For prevention, collaborative research efforts are required in developing countries, in line with the WHO approach to implement the recommendations of the 2008 Millennium Development Goals (www.un.org/millenniumgoals). This includes the "common risk factor" approach, which analyzes biological and social determinants of health alongside other chronic health problems such as diabetes and obesity, as outlined in the Marmot Health inequalities review (2008) (www.ucl.ac.uk/gheg/marmotreview). Simultaneously, orofacial cleft research should involve clinical researchers to identify inequalities in access to treatment and identify the best interventions for minimizing mortality and residual deformity. The future research agenda also requires engagement with implementation science to get research findings into practice.

Abstract
OBJECTIVE To identify factors associated with default from follow-up cervical cytology tests. METHODS A cohort study was conducted involving 2166 women, aged 20-59, with recent low-grade cervical cytology taken within the NHS Cervical Screening Programmes in Scotland and England, and managed by 6-monthly cytology in primary care. For the first (6-month) and second (12-month) surveillance cytology tests separately, women were categorized as 'on-time attendees' (attended ≤6 months of test being due), 'late attendees' (attended greater than 6 months after test was due) or 'non-attendees' (failed to attend). Multivariate odds ratios (ORs) were computed for factors associated with late and non-attendance. RESULTS For the first surveillance test, risk of non-attendance was significantly higher in younger women, those without post-secondary education, and non-users of prescribed contraception. Factors significantly associated with late attendance for the first test were the same as for non-attendance, plus current smoking and having children. The most important predictor of non-attendance for the second surveillance test was late attendance for the first test (OR = 9.65; 95% CI, 6.60-16.62). Non-attendance for the second test was also significantly higher among women who were younger, smokers and had negative cytology on the first surveillance test. Late attendance for the second surveillance test was higher in women who were younger, smokers, had children and attended late for the first test. CONCLUSIONS Women at highest risk of default from follow-up cytology tend to be young, smoke, lack post-secondary education, and have defaulted from a previous surveillance appointment. Tackling default will require development of targeted strategies to encourage attendance and research to better understand the reasons underpinning default.

Abstract
OBJECTIVE To assess the value of a single human papillomavirus (HPV) test in making decisions on management of women with cervical cytology showing borderline nuclear abnormality (BNA) or mild dyskaryosis. In particular, to determine whether information on high-risk (hr) HPV status would be valuable in the choice between (1) cytological surveillance versus immediate referral to colposcopy, and (2) at colposcopy, between biopsy and recall versus immediate large loop excision of the transformation zone (LLETZ). DESIGN Multicentre individually randomised controlled trial, nested within the NHS Cervical Screening Programmes, investigating the value of HPV testing by testing for interactions between HPV status and (1) cytological surveillance versus colposcopy, and (2) biopsy and recall versus immediate LLETZ. Setting Grampian, Tayside and Nottingham. Population Women (n = 4439), aged 20-59 years, with a cytology test showing borderline nuclear abnormalities or mild dyskaryosis during October 1999 to October 2002. METHODS High-risk HPV status was determined at recruitment using the polymerase chain reaction assay with the GP5+/6+ general primer system. The results of this HPV testing were not disclosed to either the participating women or to those involved in their management. Women were randomised to either (1) 6-monthly cytological screening in primary care or (2) referral for colposcopy. Human papillomavirus status was used to stratify both randomisations. All women were followed for 3 years, concluding with an invitation to an exit appointment at which colposcopic examination was undertaken. In addition, in women who were randomised to initial colposcopy and underwent colposcopy, the association between hrHPV status and presence of cervical intraepithelial neoplasia (CIN) grade 2 or more severe disease (henceforth CIN2 or worse) was examined. MAIN OUTCOME MEASURES Sensitivity, specificity, positive and negative predictive values of the HPV test for predicting CIN2 or worse and the implications for the choice of management between cytological surveillance and immediate referral for colposcopy. RESULTS There were no significant interactions between management and HPV status. Hence, in women with mild dyskaryosis or BNA who are HPV positive, there is no advantage of (1) immediate colposcopy over cytological surveillance (P = 0.76) or (2) immediate LLETZ over biopsy and recall (P = 0.27). The sensitivity of HPV testing for detection of CIN2 or worse was 75.2% (95% CI 68.8-81.0%) among women with mild dyskaryosis and 69.9% (95% CI 61.7-77.3%) among those with BNA. Specificity was higher in those with BNA (71.3%; 95% CI 68.5-74.1%) than in those with mild dyskaryosis (46.9%; 95% CI 42.2-51.6%). Sensitivity decreased with increasing age whereas specificity increased. The negative predictive value was high, particularly among women with BNA (94.5%; 95% CI 92.9-96.0%). Across all ages, 22% of women who had CIN2 or worse were HPV negative. Conversely, 40% of those who were HPV positive did not have CIN. HPV was a much more reliable predictor in women aged over 40 years. CONCLUSIONS We conclude that in younger women with low-grade cytological abnormalities, a single HPV test would not be useful in determining who should be referred for colposcopy or the most effective management at colposcopy. In women over 40, a negative HPV test could be used to rule out further investigation.

Abstract
Worldwide, over 1 million cases of colorectal cancer (CRC) were reported in 2002, with a 50% mortality rate, making CRC the second most common cancer in adults. Certain racial/ethnic populations continue to experience a disproportionate burden of CRC. A common polymorphism in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene has been associated with a lower risk of CRC. The authors performed both a meta-analysis (29 studies; 11,936 cases, 18,714 controls) and a pooled analysis (14 studies; 5,068 cases, 7,876 controls) of the C677T MTHFR polymorphism and CRC, with stratification by racial/ethnic population and behavioral risk factors. There were few studies on different racial/ethnic populations. The overall meta-analysis odds ratio for CRC for persons with the TT genotype was 0.83 (95% confidence interval (CI): 0.77, 0.90). An inverse association was observed in whites (odds ratio = 0.83, 95% CI: 0.74, 0.94) and Asians (odds ratio = 0.80, 95% CI: 0.67, 0.96) but not in Latinos or blacks. Similar results were observed for Asians, Latinos, and blacks in the pooled analysis. The inverse association between the MTHFR 677TT polymorphism and CRC was not significantly modified by smoking status or body mass index; however, it was present in regular alcohol users only. The MTHFR 677TT polymorphism seems to be associated with a reduced risk of CRC, but this may not hold true for all populations.

Abstract
BACKGROUND Expanded newborn screening generates incidental results, notably carrier results. Yet newborn screening programmes typically restrict parental choice regarding receipt of this non-health serving genetic information. Healthcare providers play a key role in educating families or caring for screened infants and have strong beliefs about the management of incidental results. METHODS To inform policy on disclosure of infant sickle cell disorder (SCD) carrier results, a mixed-methods study of healthcare providers was conducted in Ontario, Canada, to understand attitudes regarding result management using a cross-sectional survey (N = 1615) and semistructured interviews (N = 42). RESULTS Agreement to reasons favouring disclosure of SCD carrier results was high (65.1%-92.7%) and to reasons opposing disclosure was low (4.1%-18.1%). Genetics professionals expressed less support for arguments favouring disclosure (35.3%-78.8%), and more agreement with arguments opposing disclosure (15.7%-51.9%). A slim majority of genetics professionals (51.9%) agreed that a reason to avoid disclosure was the importance of allowing the child to decide to receive results. Qualitatively, there was a perceived "duty" to disclose, that if the clinician possessed the information, the clinician could not withhold it. DISCUSSION While a majority of respondents perceived a duty to disclose the incidental results of newborn screening, the policy implications of these attitudes are not obvious. In particular, policy must balance descriptive ethics (ie, what providers believe) and normative ethics (ie, what duty-based principles oblige), address dissenting opinion and consider the relevance of moral principles grounded in clinical obligations for public health initiatives.

Abstract
Effective treatment of chronic pain with morphine is limited by decreases in the drug's analgesic action with chronic administration (antinociceptive tolerance). Because opioids are mainstays of pain management, restoring their efficacy has great clinical importance. We have recently reported that formation of peroxynitrite (ONOO(-), PN) in the dorsal horn of the spinal cord plays a critical role in the development of morphine antinociceptive tolerance and have further documented that nitration and enzymatic inactivation of mitochondrial superoxide dismutase (MnSOD) at that site provides a source for this nitroxidative species. We now report for the first time that antinociceptive tolerance in mice is also associated with the inactivation of MnSOD at supraspinal sites. Inactivation of MnSOD led to nitroxidative stress as evidenced by increased levels of products of oxidative DNA damage and activation of the nuclear factor poly (ADP-ribose) polymerase in whole brain homogenates. Co-administration of morphine with potent Mn porphyrin-based peroxynitrite scavengers, Mn(III) 5,10,15,20-tetrakis(N-ethylpyridinium-2-yl)porphyrin (MnTE-2-PyP5+) and Mn(III) 5,10,15,20-tetrakis(N-n-hexylpyridinium-2-yl)porphyrin (MnTnHex-2-PyP5+) (1) restored the enzymatic activity of MnSOD, (2) attenuated PN-derived nitroxidative stress, and (3) blocked the development of morphine-induced antinociceptive tolerance. The more lipophilic analogue, MnTnHex-2-PyP5+ was able to cross the blood-brain barrier at higher levels than its lipophylic counterpart MnTE-2-PyP5+ and was about 30-fold more efficacious. Collectively, these data suggest that PN-mediated enzymatic inactivation of supraspinal MnSOD provides a source of nitroxidative stress, which in turn contributes to central sensitization associated with the development of morphine antinociceptive tolerance. These results support our general contention that PN-targeted therapeutics may have potential as adjuncts to opiates in pain management.

Abstract
Objectives: We sought to determine the associations between nonsyndromic cleft lip with or without cleft palate (CL−P) and cleft palate only (CP) and maternal intake of dietary folate and supplemental folic acid, in an area where the prevalence at birth of neural tube defects has been high and flour is not fortified with folic acid. Methods: Interviews regarding periconceptional dietary intake and supplement use were completed with the mothers of 112 CL−P cases, 78 CP cases, and 248 unaffected infants. The data were analyzed by logistic regression methods. Results: There was no overall association between CL−P and CP and either energy-adjusted total folate intake or supplemental folic acid use, irrespective of dosage. Conclusion: Overall, higher intakes of total folate do not appear to prevent oral clefts in this population.

Abstract
Objective: To investigate associations between nonsyndromic oral clefts and biochemical measures of folate status and the MTHFR C677T variant in the United Kingdom, where there has been no folic acid fortification program. Method: Dietary details were obtained from the mothers of 112 cases of cleft lip with or without cleft palate (CL±P), 78 cleft palate only (CP) cases, and 248 unaffected infants. Infant and parental MTHFR C677T genotype was determined. Red blood cell (RBC) and serum folate and homocysteine levels were assessed in 12-month postpartum blood samples from a subset of mothers. The data were analyzed by logistic and log-linear regression methods. Results: There was an inverse association between CL±P and maternal MTHFR CT (odds ratio [OR] = 0.5, 95% confidence interval [CI] = 0.31–0.95) and TT (OR = 0.6, 95% CI = 0.21–1.50) genotypes, with similar risk estimates for CP. There was no clear association with infant MTHFR genotype. Higher levels of maternal postpartum RBC and serum folate were associated with a lower risk for CL±P and an increased risk for CP. Higher levels of serum homocysteine were associated with a slightly increased risk for both CL±P and CP. Conclusion: While the inverse relation between the mother's having the MTHFR C677T variant and both CL±P and CP suggests perturbation of maternal folate metabolism is of etiological importance, contrasting relations between maternal postpartum levels of RBC and serum folate by type of cleft are difficult to explain.

Abstract
The inheritance of most forms of epilepsy is usually considered to be multifactorial, although a number of single gene causes are known. Most previous studies of epilepsy genetics have implicated ion channel genes or ligand receptors. In a previous study of children with adverse effects of prenatal exposure to antiepileptic drugs, we noted an increased frequency of the methylene tetrahydrofolate reductase (MTHFR) 677C>T polymorphism in the mothers. To investigate this further, a new cohort of women with epilepsy has been identified from maternity hospital records and genotyped for polymorphisms in MTHFR, serine hydroxymethyl transferase (SHMT1), methionine synthase (MTR) and methionine synthase reductase (MTRR). Healthy blood donors were genotyped as controls. The frequency of the MTHFR 677TT genotype was significantly higher in women with idiopathic generalised epilepsy than in healthy controls (p=0.012, OR 2.26, 95%CI 1.13-4.51). No association was detected for the other polymorphisms tested. The MTHFR 677C>T polymorphism may be a susceptibility factor for epilepsy, and its higher frequency in women with epilepsy may contribute to the increased risk of malformation in children of women with epilepsy.
