Introduction: One of the blacksmith industry centers in South Sumatra is in Limbang Jaya I, Ogan Ilir. Informal businesses such as blacksmiths are businesses that do not have operational standards in their work processes. Various risks from the work process can, therefore, arise, from injury to hearing loss. Therefore, it is necessary to carry out risk analysis in the work of blacksmith sector using Preliminary Hazard Analysis. Methods: This study used a descriptive research method with a qualitative approach through in-depth interviews, hazard checklists, and PHA worksheets. There were 12 informants in this study consisting of 4 key informants and 8 blacksmith worker informants. Results: The results showed that the hazards identified based on the work process were physical hazards, chemical hazards, ergonomic hazards, and psychosocial hazards. The efforts could be made by performing audiometric checks on workers, working time arrangements, stretching before and after work, and the use of Personal Protective Equipment (PPE). Conclusion: Based on the results of risk ranking, it is known that out of 34 lists of hazards that existed in the blacksmith's work process in Limbang Jaya 1 Village, there were 8 types of hazards included in the high risk group, 12 hazards included in the serious risk group, 12 hazards included in the medium risk group, and 2 hazards included in the low risk group.Keywords: blacksmith, preliminary hazard analysis, risk management

Abstract Background New Japanese ethical guidelines for medical researches and the Clinical Trials Act have come into effect and monitoring is mandated for intervention studies. Methods of monitoring can be modified according to a study risk, but there is no established method in Japan regarding how to assess a study risk. EORTC assesses a study risk using their own study risk calculator and classifies their trials into three categories. For each category, different levels of monitoring are applied. This project is aimed to assess the study risks of JCOG trials using the EORTC calculator. Methods We selected clinical trials open to patient recruitment in JCOG as of Nov 2014. Each trial was scored based on the EORTC study risk calculator and classified into three risk categories; low, medium and high. Results A total of 40 studies were included in the assessment. Twenty-seven studies (67.5%) were classified into low risk group, 12 (30%) in medium risk group, and only 1 (2.5%) in high risk group. Clinical trials evaluating multimodality therapy and/or using unapproved drugs tended to be scored higher and most of them were classified into medium or high risk group. Conclusions JCOG conducts central monitoring and site visit audit with sampling source data verification for every trial, which are almost compatible with the way in EORTC for the medium risk group. Because most of the JCOG studies were classified into low or medium risk group, the intensity of monitoring and audit in JCOG was considered as reasonable even from the EORTC perspective.

Introduction: Cardiovascular risk assessment may help in the identification of symptom-free subjects with high cardiovascular risk. Aim: The author studied the correlation between SCORE and Reynolds risk assessment systems based on data from the cardiovascular risk screening program carried out in subjects without cardiovascular disease. Method: Data obtained from 4462 subjects (1977 men and 2485 women; mean age, 47,4 years) were analysed. The comparison was based on risk categories of the SCORE system. Results: There was a strong correlation between the two scoring systems in the low risk population (under <2% SCORE risk the Spearman rho = 1, p < 0.001). A weak correlation was found in the medium risk group (between 3–4% the Spearman rho = 0.59–0.49, p < 0.001 and between 10–14% the Spearman rho = 0.42, ns.) and a stronger correlation in the high risk group (>15% the Spearmen rho = 0.8, p = 0.017). When correlations were analysed in gender and age categories, the weakest correlation was detected in medium risk women over 40 years of age. In cases when the differences between the two scoring systems were significant, the hsCRP levels were significantly higher (4.1 vs. 5.67 mg/L, p < 0.001). Conclusions: Introduction of hsCRP into cardiovascular risk assessments can refine the risk status of symptom-free subjects, especially among intermediate risk middle-age women (two-step risk assessment).

This present study examines the sexual and general recidivism rates of 547 convicted sex offenders released before and after the enactment of Megan’s Law in New Jersey. Presenting the longest Megan’s Law evaluation, participants were followed for an average of 15 years after release (range = 10-29 years). Bivariate and multivariate logistic regression equations were estimated to identify covariates significantly associated with both sexual and general recidivism. Group-based trajectories of general recidivism within the 10 years post–prison release were also estimated and compared according to pre–Megan’s Law and post–Megan’s Law release status. No differences in recidivism rates were noted between the cohorts, but differences emerged in the offending trajectories of the high-risk group of offenders within 10 years of release. These results highlight the lack of impact that sex offender registration and notification (SORN) laws have on sexual and general reoffending rates postrelease.

Abstract PurposeHepatocellular carcinoma (HCC) patients with alpha-fetoprotein (AFP)-negative (<8.78 ng/mL) have special clinicopathologic characteristics and prognosis. The aim of this study was to apply a new method to establish and validate a new model for predicting the prognosis of HCC patients with AFP-negative.Materials and MethodsA total of 410 AFP-negative patients with clinical diagnosed with HCC as a primary cohort; 148 AFP-negative HCC patients as an independent validation cohort. In primary cohort, independent factors for overall survival (OS) by LASSO Cox regression were all contained into the nomogram1; by univariate and multivariate Cox hazard analysis were all contained into the nomogram2. Nomograms performance and discriminative power were assessed with concordance index (C-index) values, area under curve (AUC), Calibration curve and decision curve analyses (DCA). The results were validated in the validation cohort.ResultsThe C-index of nomogram1was 0.708 (95%CI: 0.673-0.743), which was superior to nomogram2 (0.706) and traditional modes (0.606-0.629). The AUC of nomogram1 was 0.736 (95%CI: 0.690-0.778). In the validation cohort, the nomogram1 still gave good discrimination (C-index: 0.752, 95%CI: 0.691-0.813; AUC: 0.784, 95%CI: 0.709-0.847) and good calibration. The calibration curve for probability of OS showed good homogeneity between prediction by nomogram1 and actual observation. DCA demonstrated that nomogram1 was clinically useful. Moreover, patients were divided into three distinct risk groups for OS by the nomogram1: low-risk group, middle-risk group and high-risk group, respectively.ConclusionsNovel nomogram based on LASSO Cox regression presents more accurate and useful prognostic prediction for patients with AFP-negative HCC. This model could help AFP-negative HCC facilitate a personalized prognostic evaluation.

e17516 Background: Distant metastasis is a main determinant of prognosis in patients with nasopharyngeal carcinoma(NPC). We explored the patterns of disease spread in NPC patients and identified the pattern correlates with distant metastases. Methods: The imaging documents of 1300 consecutive newly diagnosed nasopharyngeal carcinoma between 2012 and 2016 were reviewed. According to the incidence rates of tumor invasion, the anatomic sites were classified into high-risk group (≥50%), medium-risk group (≥10%~ < 50%) and low-risk group ( < 10%). The location of lymph nodes was determined by 2013 updated guidelines for neck node levels. Additionally, we developed a novel classification based on tumor spreading patterns, as shown in Table. Moreover, we validated the prognostic accuracy of the classification in a validation cohort from a different institution, 241 non-metastatic NPC patients were retrospectively enrolled. Kaplan-Meier method and log-rank test were used to analyze all time-to-event data. Results: The incidence rates of tumor invasion were 0.2% ~91.2%, 95.2% cases across the midline. If anatomic sites in high-risk group or median-risk group were involved, the incidence rates in adjacent medium-risk sites or low-risk group were increased. On the contrary, the incidence rates were decreased when the adjacent high-risk sites or median-risk group were not involved. 85.9% cases had involved lymph nodes. Only 3.9% had skip metastases. The incidence rates of nodal involvement were increased when adjacent upper nodal level was involved. In validation cohort, distant metastases were present in 32/241 NPC patients (13.3%) and 3-year distant metastasis-free survival(DMFS) in local, superior, inferior, and mixed type were 95.0%, 91.3%, 89.0%, and 78.7%, respectively. Cumulative survival curves for former three patterns were relatively similar and were clearly separated from mixed type. DMFS was significantly lower for patients with mixed type pattern than for those with other patterns(P = 0.018). Conclusions: Local disease in NPC patients spreads stepwise from proximal sites to more distal sites. The frequency of metastases in the jugular lymph node chains decreased in the cranio-caudal direction. Based on the patterns of tumor extension, an imaging-based predictor of distant metastases was developed and may be used as a prognostic marker for selecting patients to further systemic treatments.

Abstract Introduction: While remission rates for childhood acute lymphoblastic leukemia (ALL) now exceed 80%, relapsed ALL remains the leading cause of non-traumatic death in children. Recently, a high-risk group of B-progenitor ALL patients has been identified. Such cases exhibit a gene expression profile similar to that of BCR-ABL1 positive (Ph+) ALL but are BCR-ABL1 negative, and also experience poor treatment outcomes. This subset, termed Ph-like ALL, is characterised by a range of genetic alterations that activate cytokine receptor and kinase signalling, allowing potential targeting by available tyrosine kinase inhibitors (TKI). The frequency of Ph-like ALL in the Australian community and the prognosis in the setting of the first MRD (minimal residual disease) intervention trial by the Australian and New Zealand Children's Haematology/Oncology Group (ANZCHOG ALL8) is unknown. Method: We retrospectively screened 250 unselected samples that were available from children diagnosed with B-ALL, for Ph-like ALL. The children, aged between 1 and 18 years, were enrolled on the ANZCHOG ALL8 trial and recruited from 2002-2011. The criteria for stratification to the high-risk group, based upon Berlin-Frankfurt-Munster (BFM) protocols, were BCR-ABL1 or MLL t(4;11) translocation; poor prednisolone response at day 8; failure to achieve remission by day 33 or high MRD (>5 x10-4) at day 79. MRD was measured by RQ-PCR for patient-specific immunoglobulin and T-cell receptor rearrangements. All patients received a standard BFM four drug induction chemotherapy regimen including a prednisolone pre-phase and intrathecal methotrexate. High-risk patients received a further three novel intensive blocks of chemotherapy followed by transplant in most cases. Patients were screened for Ph-like ALL using a custom Taqman Low Density Array (TLDA) based upon previous reports. Fusions were then confirmed by RT-PCR for 30 known fusions, Sanger sequencing, mRNA sequencing and/or FISH. Results: Ten percent (25/250) of children in this cohort were identified as having Ph-like ALL, with most fusions converging on kinase activating pathways (Table 1). Three Ph-like ALL patients were considered high-risk, the remaining 22 (88%) were medium risk. Five children with Ph-like ALL, that did not have a fusion identified by RT-PCR, are currently under further investigation. Furthermore, 15 of the 20 (75%) of rearrangements involved CRLF2 with 10 (66%) of these children relapsing. Strikingly, 56% (14/25) of children in the ALL8 cohort who were identified as Ph-like subsequently relapsed compared to 16% (36/225) who were not, with significantly worse event free survival (p<0.0001) (Figure 1). Conclusion: Here we demonstrate a significantly higher frequency of relapse amongst Australian children with Ph-like ALL compared to non Ph-like disease despite a MRD-adjusted intensification regimen. In this cohort, these children should be classified as high-risk due to high treatment failure rates with standard/medium risk regimens. Importantly, rapid identification of these patients may guide future intervention with targeted therapies, such as TKI, matched to the causative genetic lesion in this high-risk group. Figure 1.

Abstract Background and study aim The European guidelines for quality assurance in colorectal cancer screening and diagnosis contain postpolypectomy surveillance recommendations. They recommend follow-up intervals depending on the findings at index colonoscopy, and divide patients into a low-, intermediate- or high-risk group. The aim of this study was to assess the adherence of Austrian endoscopists to the European guidelines and to determine whether sending a reminder letter resulted in better adherence. Methods A single reminder letter containing the guidelines was sent to all endoscopists who participated in the Certificate of Quality for Screening Colonoscopy program in Austria. Adherence was assessed before and after the letter had been sent. Factors associated with adherence were investigated. Results We found poor baseline adherence to the guidelines. After the reminder letter, the adherence slightly improved in the low-risk group, but did not change in the intermediate-risk or high-risk groups. An adenoma detection rate of at least 20 % was associated with higher adherence rates. Generally, internists and hospitals showed better adherence compared with surgeons and private practices, respectively, both before and after the reminder letter. Conclusion A single reminder letter was not enough to improve the poor adherence to the European postpolypectomy surveillance guidelines. Thus, future studies are required to identify and eliminate all factors responsible for nonadherence to postpolypectomy guidelines in order to reach the goal of a safe, effective, and cost-effective colorectal cancer prevention tool in the near future.

OBJECTIVEThe ability to assess the risk of adverse events based on known patient factors and comorbidities would provide more effective preoperative risk stratification. Present risk assessment in spine surgery is limited. An adverse event prediction tool was developed to predict the risk of complications after spine surgery and tested on a prospective patient cohort.METHODSThe spinal Risk Assessment Tool (RAT), a novel instrument for the assessment of risk for patients undergoing spine surgery that was developed based on an administrative claims database, was prospectively applied to 246 patients undergoing 257 spinal procedures over a 3-month period. Prospectively collected data were used to compare the RAT to the Charlson Comorbidity Index (CCI) and the American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) Surgical Risk Calculator. Study end point was occurrence and type of complication after spine surgery.RESULTSThe authors identified 69 patients (73 procedures) who experienced a complication over the prospective study period. Cardiac complications were most common (10.2%). Receiver operating characteristic (ROC) curves were calculated to compare complication outcomes using the different assessment tools. Area under the curve (AUC) analysis showed comparable predictive accuracy between the RAT and the ACS NSQIP calculator (0.670 [95% CI 0.60–0.74] in RAT, 0.669 [95% CI 0.60–0.74] in NSQIP). The CCI was not accurate in predicting complication occurrence (0.55 [95% CI 0.48–0.62]). The RAT produced mean probabilities of 34.6% for patients who had a complication and 24% for patients who did not (p = 0.0003). The generated predicted values were stratified into low, medium, and high rates. For the RAT, the predicted complication rate was 10.1% in the low-risk group (observed rate 12.8%), 21.9% in the medium-risk group (observed 31.8%), and 49.7% in the high-risk group (observed 41.2%). The ACS NSQIP calculator consistently produced complication predictions that underestimated complication occurrence: 3.4% in the low-risk group (observed 12.6%), 5.9% in the medium-risk group (observed 34.5%), and 12.5% in the high-risk group (observed 38.8%). The RAT was more accurate than the ACS NSQIP calculator (p = 0.0018).CONCLUSIONSWhile the RAT and ACS NSQIP calculator were both able to identify patients more likely to experience complications following spine surgery, both have substantial room for improvement. Risk stratification is feasible in spine surgery procedures; currently used measures have low accuracy.

Background Case-mix comorbidities and malnutrition influence outcome in continuous ambulatory peritoneal dialysis (CAPD) patients. In the present study, we analyzed the influence of stratified comorbidities on nutrition indices and survival in CAPD patients. Patients and Methods We categorized 373 CAPD patients (197 with and 176 without diabetes) into three risk groups: low—age under 70 years and no comorbid illness; medium—age 70 – 80 years, or any age with 1 comorbid illness, or age under 70 years with diabetes; high—age over 80 years, or any age with 2 comorbid illnesses. We then compared nutrition indices and malnutrition by subjective global assessment (SGA) between the three groups. Survival was compared using Kaplan–Meier survival analysis. Results Mean daily calorie and protein intakes in the low-risk group (21 ± 6.7 Kcal/kg, 0.85 ± 0.28 g/kg) were significantly higher than in the medium- (17.6 ± 5.2 Kcal/kg, 0.79 ± 0.25 g/kg) and high-risk (17.5 ± 6.1 Kcal/kg, 0.78 ± 0.26 g/kg) groups ( p = 0.001 and p = 0.04 respectively). Relative risk (RR) of malnutrition was less in the low-risk group (103/147, 70.06%) than in the medium-risk group [135/162, 83.3%; RR: 2.0; 95% confidence interval (CI): 2.1 to 3.4; p = 0.01] or the high-risk group (54/64, 84.4%; RR: 2.3; 95% CI: 2.1 to 4.9; p = 0.03). Mean survivals of patients in the low-, medium-, and high-risk groups were 51 patient–months (95% CI: 45.6 to 56.4 patient–months), 43.3 patient–months (95% CI: 37.8 to 48.7 patient–months), and 29.7 patient–months (95% CI: 23 to 36.4 patient–months) respectively (log-rank: 35.9 patient–months; p = 0.001). The 1-, 2-, 3-, 4-, and 5-year patient survivals in the low-, medium-, and high-risk groups were 96%, 87%, 79%, 65%, and 56%; 89%, 67%, 54%, 43%, and 34%; and 76%, 48%, 31%, 30%, and 30% respectively. Conclusions Intake of calories and protein was significantly lower in the medium-risk and high-risk groups than in the low-risk group. Survival was significantly better in low-risk patients than in medium- and high-risk patients.

Background: This study focused on the identification of risk profiles for institutionalization among older adults diagnosed with cognitive impairment-not dementia or dementia in 1991/92 and subsequent institutionalization in the following 5-year period. Methods: Data were from a sample of 123 individuals aged 65+ and their unpaid caregivers in Manitoba, Canada. Cluster analysis was conducted using baseline characteristics of age, cognition, disruptive behaviors, ADLs/IADLs, use of formal in-home services, and level of caregiver burden. Results: Three distinct groups emerged (high-risk [n = 12], medium risk [n = 40], and low risk [n = 71]). The high-risk group had the poorest cognitive scores, were the most likely to exhibit disruptive behaviors, were the most likely to need assistance with ADLs and IADLs, and had the highest level of burden among their caregivers. Follow-up of the groups validated the risk profiles; 75% of the high-risk group were institutionalized within the next 5 years, compared to 45% of the medium-risk group and 21% of the low-risk group. Discussion: The risk profiles highlight the diversity among individuals with cognitive impairment and the opportunity for differential targeting of services for the distinct needs of each group.
