Objective:: To determine the cost-effectiveness of the HiBalance training program for managing Parkinson's disease (PD)-related balance and gait disorders., Design:: Cost comparison design following the randomized controlled trial comparing a novel balance training intervention with care as usual., Subjects:: A total of 100 participants with mild-moderate PD were randomized to either the intervention ( n = 51) or the control group ( n = 49)., Intervention:: A 10-week (three times per week), group-based, progressive balance training program, led by two physical therapists., Main Outcomes:: All program costs were collected for both groups. Cost-utility was evaluated using quality-adjusted life years (QALYs) and cost-effectiveness measures were the Mini Balance Evaluation Systems Test (Mini-BESTest; assessing balance performance) and gait velocity. Incremental cost-effectiveness ratios were calculated and a probabilistic sensitivity analysis was conducted., Results:: The between-group difference in QALYs was 0.043 (95% confidence interval (CI): 0.011-0.075), favoring the intervention group. Between-group differences in balance performance and gait velocity were 2.16 points (95% CI: 1.19-3.13) and 8.2 cm/second (95% CI: 2.9-13.6), respectively, favoring the intervention group. The mean cost per participant in the intervention group was 16,222 SEK (€1649) compared to 2696 SEK (€274) for controls. The estimated incremental cost-effectiveness ratios were 314,558 SEK (€31,969) for an additional QALY, 6262 SEK (€631) for one point improvement in balance performance, and 1650 SEK (€166) for 1 cm/second increase in gait velocity. Sensitivity analyses indicated a high probability (85%) of program success., Conclusion:: In terms of QALYs, the HiBalance program demonstrated a high probability of cost-effectiveness in the short-term perspective when considering the willingness-to-pay thresholds used in Europe.

Background and Purpose: Although increasing evidence supports the benefit- of exercise among people with Parkinson disease (PwPD), it is unclear whether a given exercise modality suits all PwPD, given the heterogeneity of the disease. The purpose of this study was to explore factors associated with responsiveness to a highly challenging training intervention that incorporated dual-task exercises., Methods: Forty-seven PwPD (mean age: 73 years; 19 females, Hoehn and Yahr stages 2-3) who had participated in 10 weeks of highly challenging gait and balance training were included. Baseline demographics, disease-related factors, physical and cognitive ability, and perceived health were used for the prediction of percent change in balance performance (the Mini-BESTest) and comfortable gait speed between the pre- and postassessments, using multiple linear regression analyses., Results: Thirty-five percent of the variance of change in balance performance was explained by General Health Perceptions (β = -0.36), the Timed Up and Go test (β = -0.33), and the single-task performance of a cognitive task (β = -0.24). Forty-nine percent of change in gait speed was explained by gait speed while performing a dual task (β = -0.46), dual-task interference while walking (β = 0.43), time to complete the Timed Up and Go test (β = -0.29), and percent error on a cognitive task (β = -0.25)., Discussion and Conclusions: The results may suggest that the PwPD with overall lower perceived health, functional mobility, and cognitive functions are the ones most likely to benefit from highly challenging and attention-demanding gait and balance training.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A240).

Purpose: To investigate objectively measured physical activity in stroke survivors living in low-income areas of Cape Town, South Africa, specifically to: (a) describe the volume of daily physical activity and time spent in different intensity levels and (b) investigate the association of factors covering the International Classification of Functioning, Disability and Health with sedentary behavior., Materials and Methods: A cross-sectional design was used, where forty-five ambulatory community-dwelling stroke survivors participated. Volume and intensity of physical activity were assessed with accelerometers for three to five consecutive days. Personal and environmental factors, along with body function and activity, were captured. Multiple linear regression was used to investigate factors associated with the percentage of days spent sedentary., Results: The median number of steps per day was 2393, and of the average 703 minutes of wear time, 80% were spent in sedentary, 15% in light, and 5% in moderate-to-vigorous intensity physical activity. Age, stroke severity, and failing to receive outpatient rehabilitation were independently associated with sedentary, which, taken together, explained 52% of the variance., Conclusions: Low volumes of physical activity and high amount of sedentary time emphasize the need to develop strategies that will increase physical activity. Providing outpatient rehabilitation in a systematic manner post-stroke is a potential target of health care programs in order to reduce sedentary behavior. Implications for rehabilitation Objectively measured physical activity among community-dwelling survivors of stroke in Cape Town, South Africa was low in volume, and the majority did not meet the recommendations of 150 minutes of at least moderate intensity physical activity. The majority of stroke survivors in South Africa spent most of their time sedentary, which could further increase the risk of cardiovascular impairments. Outpatient rehabilitation should be provided to all patients after stroke since it appears to reduce sedentary time.

Background: Translating evidence into practice requires adaptation to facilitate the implementation of efficacious interventions. A novel highly challenging balance training program (HiBalance) was found to improve gait, balance, and physical activity in persons with Parkinson's disease (PD) in an earlier randomized controlled trial. This study aimed to describe the adaptation process and feasibility of implementing the HiBalance program for PD within primary healthcare settings., Method: Feasibility was assessed in terms of study processes and scientific evaluation. Nine persons with mild-moderate PD were enrolled in this pre-post feasibility study. The dose of the original program was adapted by reducing therapist-led training sessions from three to two times weekly. Outcome measures were substituted with ones more clinically feasible. One group (n = 5) received HiBalance training three times weekly for 10 weeks while another (n = 4) trained twice weekly plus a once weekly home exercise program (HEP). Balance performance was the primary outcome, while secondary outcomes (e.g., gait speed, physical activity level, concerns of falling, and health-related quality of life) were also evaluated., Results: Regarding process feasibility, attendance was high (approximately 90%) in both groups, and experiences of the group and home training were positive. Newly selected outcome measures were feasible. The scientific evaluation revealed few adverse events and no serious injuries occurred. Concerning outcomes per group, the average change in balance performance and gait speed was equal to, or exceeded, the minimally worthwhile treatment effect commonly used in PD., Conclusion: The findings support the feasibility, in terms of process and scientific evaluation, of the adapted HiBalance program for implementation within clinical settings. A sufficiently powered study is required to ascertain whether the newly proposed program offers similar short and long-term effects as the original program., (© 2018 The Authors.

Background: The provision of specialized care in a time-sensitive manner has shown to be crucial for survival and recovery of functioning after a traumatic spinal cord injury (TSCI). However, little is known about the provision of TSCI care in different international contexts; information which is required for strengthening policy and practice. Aims: The overarching aim of this study will be to explore health care processes and outcomes of TSCI care in South Africa and Sweden. Specific aims will be to: (1) describe acute processes of TSCI care, (2) determine acute- and long-term outcomes of TSCI care, and (3) identify predictors for survival, secondary complications, and functioning 12 months post-injury. Methods: A prospective (regional), population-based cohort study where adults with an acute TSCI will be recruited over at least a 1-year period from the City of Cape Town, South Africa, and Stockholm, Sweden. The anticipated sample size inclusive of both international contexts will be 200 participants-based on a power calculation for detecting differences in mortality. Information on the nature and timing of processes of acute care (e.g., transfer logistics, spinal surgery, and specialized SCI care) will be collected on acute care admission and discharge using a standardized form. Survival status, secondary complications, neurological symptoms, functional status, activity, and participation as well as health-related quality of life will be collected at discharge from SCI acute care and at 12-months post-injury. Secondary complications and functioning will be compared between South Africa and Sweden using inferential statistics. To address mortality specifically, the indirect standardization method for differences in mortality between contexts will be used whereby Stockholm will serve as standard for specialize care. For the assessment of factors related to mortality and other outcomes (e.g., neurological and secondary health conditions) multivariate regression analyses will be used to determine independent risk factors. Conclusion: This study offers a unique investigation of the relationship between health care processes and outcomes of TSCI care with the aim of strengthening management guidelines for SCI in South Africa and Sweden.

Objective: To investigate the feasibility of using accelerometers to monitor physical activity in persons with stroke admitted to inpatient rehabilitation., Design: Longitudinal observational study., Participants: Persons with stroke admitted to a specialized rehabilitation centre for sub-acute rehabilitation were recruited between August and December 2016., Methods: Volume and intensity of physical activity were assessed with accelerometers throughout the rehabilitation period. Indicators of feasibility included processes (recruitment, protocol adherence and participants' experiences) and scientific feasibility, which assessed the accelerometers' ability to detect change in physical activity among stroke survivors who ambulate independently and those who are dependent on a mobility device., Results: Twenty-seven out of 31 eligible individuals took part in this study, with 23 (85%) completing it. In total, 432 days of rehabilitation were monitored and valid physical activity data were obtained for 408 days (94%). There were no indications that the measurement interfered with participants' ability to participate in rehabilitation. Despite the subjects' ambulation status, the number of steps and time spent in moderate-to-vigorous physical activity increased significantly across the first 18 days of rehabilitation, whereas sedentary time was unchanged., Conclusion: This study supports the feasibility of using accelerometers to capture physical activity behaviour in survivors of stroke during inpatient rehabilitation.

Background: Good conceptual knowledge is an essential requirement for health professions students, in that they are required to apply concepts learned in the classroom to a variety of different contexts. However, the use of traditional methods of assessment limits the educator's ability to correct students' conceptual knowledge prior to altering the educational context. Concept mapping (CM) is an educational tool for evaluating conceptual knowledge, but little is known about its use in facilitating the development of richer knowledge frameworks. In addition, structured feedback has the potential to develop good conceptual knowledge. The purpose of this study was to use Kinchin's criteria to assess the impact of structured feedback on the graphical complexity of CM's by observing the development of richer knowledge frameworks., Methods: Fifty-eight physiotherapy students created CM's targeting the integration of two knowledge domains within a case-based teaching paradigm. Each student received one round of structured feedback that addressed correction, reinforcement, forensic diagnosis, benchmarking, and longitudinal development on their CM's prior to the final submission. The concept maps were categorized according to Kinchin's criteria as either Spoke, Chain or Net representations, and then evaluated against defined traits of meaningful learning., Results: The inter-rater reliability of categorizing CM's was good. Pre-feedback CM's were predominantly Chain structures (57%), with Net structures appearing least often. There was a significant reduction of the basic Spoke- structured CMs (P = 0.002) and a significant increase of Net-structured maps (P < 0.001) at the final evaluation (post-feedback). Changes in structural complexity of CMs appeared to be indicative of broader knowledge frameworks as assessed against the meaningful learning traits., Conclusions: Feedback on CM's seemed to have contributed towards improving conceptual knowledge and correcting naive conceptions of related knowledge. Educators in medical education could therefore consider using CM's to target individual student development.

Background: Spinal cord injuries (SCIs) caused by assault present a unique challenge facing the healthcare system, in that very little is known about how these injuries manifest compared with other causes of injury. Understanding the nuances of gunshot SCIs could contribute towards better care provision., Objective: To determine the characteristics of gunshot SCI and compare both injury characteristics and outcomes between gunshot SCI and all other traumatic causes taken together., Methods: The gunshot SCI sub-cohort was derived from a 1-year prospective, population-based study, including both tertiary-level hospitals providing SCI care in the Cape Metropolitan area of South Africa (SA). All consenting 145 survivors, after a window period of 7 days, were included, and their demographic and injury characteristics were captured according to the International SCI Core Basic Data Set. Further, selected secondary medical complications (outcomes) were prospectively and routinely assessed throughout acute care. Both descriptive and inferential statistics were used to describe and compare characteristics and outcomes, respectively., Results: Of the 145 survivors of traumatic SCIs, 45 (31%) injuries were caused by gunshots. The gunshot SCI group consisted mainly of males (n=43, 96%), and the average age of injury onset was 26 years. Most survivors of the gunshot SCI group were paraplegic (69%), had complete lesions (69%) and vertebral injuries (96%), and presented with significant associated injuries (84%). When comparing gunshot SCI with all other traumatic causes, significant differences were found in relation to demographic and injury characteristics and adverse outcomes, indicating that those survivors with gunshot SCI were typically younger males with complete paraplegia, had more frequent secondary medical complications, and a longer hospital stay., Conclusion: This study contributes to the knowledge base of survivors with gunshot SCIs in a region of SA. Efforts should be made to reduce the occurrence of all gunshot SCIs, since those injuries affect survivors negatively in terms of injury characteristics and adverse outcomes.

Objectives: To update the incidence rate, aetiology and injury characteristics of acutely-injured adults with traumatic spinal cord injury in Stockholm, Sweden, using international standards of reporting., Study Design: Prospective, (regional) population-based observation., Subjects: Forty-nine consecutively enrolled individuals., Methods: A surveillance system of newly-injured adults with traumatic spinal cord injury was implemented for an 18-month period. The International Spinal Cord Injury Core Data Set was used to collect data on those who survived the first 7 days post-injury., Results: After an 18-month period, 49 incident cases were registered, of whom 45 were included in this study. The crude incidence rate was 19.0 per million, consisting mainly of men (60%), and the mean age of the cohort was 55 years (median 58). Causes of injury were almost exclusively limited to falls and transport-related events, accounting for 58% and 40% of cases, respectively. The incidence has remained stable when compared with the previous study; however, significant differences exist for injury aetiology (p = 0.004) and impairment level (p = 0.01) in that more fall- and transport-related spinal cord injury occurred, and a larger proportion of persons was left with resultant tetraplegia, in the current study, compared with more sport-related injuries and those left with paraplegia in the previous study., Conclusion: The incidence rate appeared to remain stable in Stockholm, Sweden. However, significant changes in injury aetiology and impairment-level post injury were found, compared with the previous study. There remains a need for developing fall-related prevention strategies in rehabilitation settings as well as in population-based programmes.

The aim of our study was to determine the impact of genetic polymorphisms in the caspase (CASP) genes on prognosis of hepatocellular carcinoma (HCC). We genotyped 7 potentially functional polymorphisms in CASP3, CASP7, CASP8, CASP9, CASP10 genes in 362 HCC patients of receiving surgical resection of HCC tumor. The associations of genotype and haplotype with overall survival (OS) and disease free survival (DFS) were analyzed by using the Cox proportional hazards model. We found that the CASP9 rs4645981 C allele was significantly associated with positive effect on DFS (P = 0.011 and 0.016 for CT+CC vs. TT in univariate and multivariate analysis, respectively), CT genotype was associated with a better OS of HCC than the TT genotype both in univariate and multivariate analysis (P = 0.048 and 0.041, respectively). Moreover, the CASP3 rs2705897 GT genotype showed marginally significant association with decreased OS and DFS, compared with the GG genotype. One haplotype TT/TG in CASP3 (constructed by rs12108497 T>C and rs2705897 T>G) was significantly associated with decreased OS and DFS, compared to the common haplotype TT/TT both in univariate analysis (P = 0.021 and 0.026, respectively) and multivariate analysis (P = 0.025 and 0.030, respectively). The haplotype GT/GT in CASP9 (constructed by rs4645978 A>G and rs4645981 C>T) was significantly associated with decreased DFS both in univariate and multivariate analysis (P = 0.012 and 0.010, respectively). In conclusion, the CASP9 rs4645981 polymorphism, CASP3 and CASP9 haplotypes may be useful prognosis markers for HCC patients with surgical resection of tumor.

Background: Rehabilitation medicine plays an integral part in attainment of optimal functioning after injury or disease. The National Rehabilitation Policy of South Africa (NRP) (2000) highlights the need for access to professional health care services, redistribution and optimal utilisation of resources and research in the field of disability and rehabilitation. The government further ratified the Convention on the Rights of Persons with Disabilities (CRPD) (2007), which validate the urgency in advancing the agenda of persons with disabilities. This paper outlines the methodological plan for evaluating rehabilitation services in the Western Cape, South Africa against the aims and objectives of the NRP as well as its principles and concepts. The evaluation process further focused on specific articles in the CRPD that were aligned with disability, health and rehabilitation., Methods/design: A mixed-method design was used to evaluate the alignment of rehabilitation services with the NRP in the Western Cape. Four rehabilitation study settings were selected to ensure that both inpatient and outpatient rehabilitation levels of care were covered at different contexts (rural and peri-urban). The sites were checked for the most prevalent rehabilitation-related conditions to ensure the identification of suitable instruments for measuring rehabilitation outcomes. Each study setting was linked to two researchers with one exploring the rehabilitation organizational structure of the sites and the other exploring the client outcomes after receiving rehabilitation services. Patients were evaluated at baseline and discharge, within seven days after admission and seven days prior to discharge. The evaluation was based on the rehabilitation organizational capacity to provide patient-oriented rehabilitation and the measurement of rehabilitation outcomes. Kaplan's framework of organisational capacity was used in the context of each study setting. For the measurement of service users' outcomes, the International Classification of Functioning, Disability and Health was used (ICF). Standardised outcome measures were adopted for the domains of impairment, activity and participation. The World Health Organisation Community-Based Rehabilitation guidelines were used as guiding principles and concepts as suggested in the NRP., Discussion: This is a groundbreaking methodological exploration that offers both study methods and instruments to measure rehabilitation services at both in-patient and out-patient rehabilitation services.

Background: The development of rehabilitation services promoting participation in people living with a traumatic spinal cord injury (TSCI) is of major concern for physical therapists. What the client sees as effective participation, barriers, and facilitators might be different due to their particular context. This study was conducted to gain insight into the experiences of attaining an important outcome in a developing context., Objective: The aim of this study was to explore the experiences of reclaiming participation in community-dwelling people with TSCI in South Africa., Design: This was an explorative, qualitative study with inductive content analysis., Methods: Individual semistructured interviews were conducted with 17 adults living with a TSCI in order to explore their experience of participation. The verbatim transcripts were analyzed, and the end result was an overall theme that included 4 emerging categories., Results: The theme "participation possibility" denotes the eventual involvement in life situations. Within this theme, there were 4 categories that emerged as a representation of essential aspects along the continuum of reclaiming participation: (1) dealing with the new self, (2) a journey dominated by obstacles, (3) the catalyst of participation, and (4) becoming an agent. Dealing with and recognizing these intervening conditions seem critical for clients to reconstruct the meaning that is necessary for a broader conception of participation., Limitations: The transferability of these findings to dissimilar contexts may be limited., Conclusion: Client perspectives on reclaiming participation after injury affirm the notion of eventual participation, with each person finding strategies to succeed. In order to help clients reclaim participation, health professionals should develop contextually sensitive programs that include peer mentoring and reduce the influence of hindering factors., (© 2016 American Physical Therapy Association.)

Objective: To evaluate the extent to which the rehabilitation outcome levels (ROL) and the spinal cord independence measure (SCIM) III could be mapped to the International Classification of Functioning, Disability and Health (ICF) and the brief core set for spinal cord injury (SCI) in the post-acute context., Methods: Two professionals used the published protocol to map the concepts derived from both measures to the ICF categories. Further, the endorsed categories at the second level of the ICF were used to determine the coverage of the Brief ICF Core Set for SCI., Results: Three items of the ROL could not be conceptualised within the ICF, while the rest were mapped to 42 second-level categories, mainly to the activity and participation domain. All the items of the SCIM III were mapped, yielding 52 ICF categories, mostly at the third level (32). For the mapping to the Core Set for SCI, the ROL covered five and the SCIM III all nine categories of 'activities and participation' included as the candidate categories of the brief version., Conclusion: In terms of content, the ROL appears to be a more global measure of functioning, compared with the SCIM III that covers specific 'activity' aspects as proposed in the Brief Core Set for SCI. It is thus recommended that standardised measures, such as the SCIM III, be used due to its conceptual underpinnings and coverage of important aspects. Implications for Rehabilitation Rehabilitation professionals should select appropriately validated outcome measures specific to the health condition in order to evaluate the effectiveness of rehabilitation. Rehabilitation professional working with outcome measures should be aware of the limitations of measures, in terms of content, and supplement the evaluation with appropriate standardised measures or the use of the Core Sets. To enhance evidence-based practise in routine clinical practise, standardised outcome measures should be used.

Background and Aims: Chronic pain is difficult to treat in individuals with substance use disorders and, when not resolved, can have a negative impact on substance use disorder treatment outcomes. This study tested the efficacy of a psychosocial pain management intervention, ImPAT (improving pain during addiction treatment), that combines pain management with content related to managing pain without substance use., Design: Single-site, parallel-groups randomized controlled trial comparing ImPAT to a supportive psychoeducational control (SPC) condition; follow-up assessments occurred at 3, 6 and 12 months., Setting: The Ann Arbor VA Substance Use Disorder treatment program, USA., Participants: Veterans Health Administration patients {n = 129; mean [standard deviation (SD)], age = 51.7 (9.5); 115 of 129 (89%) male; ImPAT (n = 65); SPC (n = 64)}., Intervention: ImPAT combines principles of cognitive-behavioral therapy and acceptance-based approaches to pain management with content related to avoiding the use of substances as a coping mechanism for pain. The SPC used a psychoeducational attention control treatment for alcoholism modified to cover other substances in addition to alcohol., Measurements: Primary: Pain intensity over 12 months; secondary: pain-related functioning, frequency of alcohol and drug use over 12 months., Findings: Primary: randomization to the ImPAT intervention versus SPC predicted significantly lower pain intensity {β [standard error (SE)] = -0.71 (0.29); 95% confidence interval (CI) = -1.29, -0.12}; secondary: relative to the SPC condition, those who received ImPAT also reported improved pain-related functioning [β (SE) = 0.27 (0.11); 95% CI = 0.05, 0.49] and lower frequency of alcohol consumption [β (SE) = -0.77; 95% CI = -1.34, -0.20]. No differences were found between conditions on frequency of drug use over follow-up., Conclusions: For adults with pain who are enrolled in addictions treatment, receipt of a psychological pain management intervention (improving pain during addiction treatment) reduced pain and alcohol use and improves pain-related functioning over 12 months relative to a matched-attention control condition., (Published 2016. This article is a U.S. Government work and is in the public domain in the USA.)

Current issues related to prostate cancer (PCa) clinical care (e.g., over-screening, over-diagnosis, and over-treatment of nonaggressive PCa) call for risk assessment tools that can be combined with family history (FH) to stratify disease risk among men in the general population. Since 2007, genome-wide association studies (GWASs) have identified more than 100 SNPs associated with PCa susceptibility. In this review, we discuss (1) the validity of these PCa risk-associated SNPs, individually and collectively; (2) the various methods used for measuring the cumulative effect of multiple SNPs, including genetic risk score (GRS); (3) the adequate number of SNPs needed for risk assessment; (4) reclassification of risk based on evolving numbers of SNPs used to calculate genetic risk, (5) risk assessment for men from various racial groups, and (6) the clinical utility of genetic risk assessment. In conclusion, data available to date support the clinical validity of PCa risk-associated SNPs and GRS in risk assessment among men with or without FH. PCa risk-associated SNPs are not intended for diagnostic use; rather, they should be used the same way as FH. Combining GRS and FH can significantly improve the performance of risk assessment. Improved risk assessment may have important clinical utility in targeted PCa testing. However, clinical trials are urgently needed to evaluate this clinical utility as well as the acceptance of GRS by patients and physicians.

Single-nucleotide polymorphisms (SNPs) of microRNAs (miRNAs) are considered potential markers of cancer risk and prognosis in various cancers. In the current study, the primary aim is to determine whether the miR-492G>C polymorphism (rs2289030) altered hepatocellular carcinoma (HCC) prognosis. The SNP rs2289030 of miR-492 was genotyped using DNA from blood samples of 362 HCC patients that had undergone surgical resection of a HCC tumor. The associations between overall survival and demographic characteristics, clinical features, and the SNP rs2289030 were estimated using the Cox proportional hazards model. Results showed that patients who carried the CG genotype (P  = 0.015, hazard ratio [HR] = 0.704, 95 % confidence interval [CI] 0.530-0.934) and CG+GG genotype (P = 0.011, HR = 0.703, 95 % CI 0.536-0.924) had significantly decreased risk of death compared to those with the CC genotype. Similar results were found in the multivariate analysis adjusted by tumor size and venous invasion. Further stratification analysis indicated that the effect of rs2289030 had more prominence in patients ≤50 years old and that reported ever using alcohol, male gender, a family history of HCC, being HbsAg or alpha fetoprotein (AFP) positive, differentiation I + II, presence of venous invasion or cirrhosis, multiple tumors, and pTNM stage I + II. Results from this study illustrate the potential use of miR-492 rs2289030 as a prognostic marker for HCC patients that have undergone a surgical resection of the tumor.

Genetic risk score (GRS) based on disease risk-associated single nucleotide polymorphisms (SNPs) is an informative tool that can be used to provide inherited information for specific diseases in addition to family history. However, it is still unknown whether only SNPs that are implicated in a specific racial group should be used when calculating GRSs. The objective of this study is to compare the performance of race-specific GRS and nonrace-specific GRS for predicting prostate cancer (PCa) among 1338 patients underwent prostate biopsy in Shanghai, China. A race-specific GRS was calculated with seven PCa risk-associated SNPs implicated in East Asians (GRS7), and a nonrace-specific GRS was calculated based on 76 PCa risk-associated SNPs implicated in at least one racial group (GRS76). The means of GRS7 and GRS76 were 1.19 and 1.85, respectively, in the study population. Higher GRS7 and GRS76 were independent predictors for PCa and high-grade PCa in univariate and multivariate analyses. GRS7 had a better area under the receiver-operating curve (AUC) than GRS76 for discriminating PCa (0.602 vs 0.573) and high-grade PCa (0.603 vs 0.575) but did not reach statistical significance. GRS7 had a better (up to 13% at different cutoffs) positive predictive value (PPV) than GRS76. In conclusion, a race-specific GRS is more robust and has a better performance when predicting PCa in East Asian men than a GRS calculated using SNPs that are not shown to be associated with East Asians.

Single nucleotide polymorphisms (SNPs) within microRNAs (miRNAs) are considered potential markers for risk and prognosis of various cancers. In the current study, we aimed to determine whether miR-608 rs4919510 affected hepatocellular carcinoma (HCC) prognosis. We genotyped rs4919510 using DNA from blood samples of 362 HCC patients receiving surgical resection of HCC tumor. Associations between rs4919510 and overall survival (OS) and demographic characteristics and clinical features were estimated using the Cox proportional hazards model. Results showed that HCC patients who carried the rs4919510 CC genotype had a significantly longer OS compared to those who carried the GG genotype (P = 0.013, hazard ratio [HR] = 0.600, 95 % confidence interval [CI] 0.402-0.897) and the CG + GG genotype (P = 0.033, HR = 0.681, 95 % CI 0.479-0.970) in univariate analysis. Similar results were obtained in multivariate analysis. Further stratification analysis indicated that rs4919510 was significantly associated with OS in patients who were satisfied with one of the following criteria: male gender, HbsAg-positive, α-fetoprotein (AFP)-positive, tumor size >5 cm, cirrhosis, solitary tumor, I + II pTNM stage, or no tumor capsule. Finally, a significantly higher frequency of rs4919510 CC genotype was observed in patients with cirrhosis (22.9 %, 55/240) than those without cirrhosis (14.0 %, 17/121) (P = 0.047). In conclusion, our results illustrated the potential role of miR-608 rs4919510 as a prognostic marker for HCC patients undergoing surgical resection of the tumor.

Unlabelled: Interferon (IFN)-α is a first-line therapy for chronic hepatitis B (CHB) patients but only initiates a response in a minority of patients. A genetic variant, rs7574865 in STAT4, was recently reported to be associated with risk of developing CHB and hepatitis B virus-related hepatocellular carcinoma. We aimed to determine whether this variant is associated with the response to IFNα treatment for hepatitis B e antigen (HBeAg)-positive CHB patients. We studied 466 HBeAg-positive CHB patients who received either IFNα-2b (n = 224) or pegylated IFNα-2a (n = 242) therapy for 48 weeks and were followed for an additional 24 weeks. The rate of sustained virologic response (SVR), defined as HBeAg seroconversion along with hepatitis B virus DNA level <2000 copies/mL at week 72, was compared among patients with different genotypes of rs7574865. After 48 weeks of treatment and 24 weeks off treatment, the SVR rates in the IFNα-2b and pegylated IFNα-2a therapy groups were 30.4% and 28.9%, respectively. Compared to the rs7574865 GT/TT genotype, the GG genotype (a risk factor of CHB and hepatitis B virus-related hepatocellular carcinoma) was significantly associated with a reduced SVR rate in both patients who received IFNα-2b therapy (21.1% versus 37.2%, P = 0.01) and those who received pegylated IFNα-2a therapy (18.0% versus 41.2%, P = 9.74 × 10(-5) ). In joint analysis of the 466 patients, the GG genotype was associated with an approximately half SVR rate compared to the GT/TT genotype (19.3% versus 39.1%, P = 4.15 × 10(-6) ). A multivariate logistic regression model including rs7574865 and clinical variables showed that rs7574865 was the most significant factor for the prediction of SVR., Conclusion: STAT4 rs7574865 is a reliable predictor of response to IFNα therapy for HBeAg-positive CHB patients and may be used for optimizing the treatment of CHB., (© 2015 by the American Association for the Study of Liver Diseases.)

Background: Rehabilitation is important for persons with disabilities as it contributes to their sense of autonomy, self-worth and social participation, and improves their quality of life. Improving the quality of rehabilitation services requires the dialogue of patients' perceptions with those of service providers, in order to recommend informed reform., Objective: The objective was to explore the experiences of persons with physical disabilities and service providers, regarding the multi-disciplinary rehabilitation services provided at a community-based out-patient rehabilitation centre., Methods: A qualitative, exploratory study design was used to collect the data.
