Knowledge, attitude and practice assessment of construction workers for HIV/AIDS in Sri Lanka.

Human immunodeficiency virus (HIV) prevalence is relatively lower in Sri Lanka than in other Asian countries; however, the number of HIV-infected persons has rapidly increased in recent years.



A baseline study on HIV, acquired immunodeficiency virus (AIDS), and sexually transmitted infections (STI) knowledge, attitude, and practice was conducted at two construction sites in Sri Lanka from January to February 2007 to design an effective intervention strategy for the construction workers.



Among 611 respondents (mostly males, mean age 32.8 years), nearly two-thirds lived away from home. Knowledge was fairly good on AIDS prevention but poorer on STI than on HIV. Some misconceptions were also observed. A high percentage did not consider HIV/AIDS as their own personal issue, and over 50% respondents expressed discriminatory attitudes towards HIV positives. Condom access was limited due to social and cultural norms. Mobility was not significantly associated with practice of prevention of HIV and STI.



This study showed that the construction workers were not specially at higher risk of HIV at that time. In order to minimize the potential risk of infection, however, it would be effective to reduce stigma and discrimination among them through the prevention program, working together with community or religious leaders in the areas. More comprehensive assessment among other population groups would also be beneficial to identify their risk of infection.
Abusive experiences and psychiatric morbidity in women primary care attenders.

Abusive experiences in childhood and adulthood increase risks of psychiatric morbidity in women and independently increase risks of further abuse over the lifetime. It is unclear which experiences are most damaging.



To measure lifetime prevalence of abusive experiences and psychiatric morbidity, and to analyse associations in women primary care attenders.



A cross-sectional, self-report survey of 1207 women attending 13 surgeries in the London borough of Hackney, UK. Independent associations between demographic measures, abusive experiences and psychiatric outcome were established using logistic regression.



Childhood sexual abuse had few associations with adult mental health measures, in contrast to physical abuse. Sexual assault in adulthood was associated with substance misuse; rape with anxiety, depression and post-traumatic stress disorder but not substance misuse. Domestic violence showed strongest associations with most mental health measures, increased for experiences in the past year.



Abuse in childhood and adulthood have differential effects on mental health; effects are increased by recency and severity. Women should be routinely questioned about ongoing and recent experiences as well as childhood.
Docetaxel combined with vinorelbine: phase I results and new study designs.

This was a phase I dose-finding and pharmacokinetic study of vinorelbine (Navelbine) and docetaxel (Taxotere) as first-line chemotherapy for metastatic breast cancer. Vinorelbine dose, 20 or 22.5 mg/m2, on days 1 and 5, was followed on day 1 by docetaxel every 21 days, in doses increasing from 60 to 100 mg/m2. Two maximum tolerated doses were reached, the first at 75 mg/m2 of docetaxel and 22.5 mg/m2 of vinorelbine, and the second at 100 mg/m2 of docetaxel and 20 mg/m2 of vinorelbine. Symptomatic peripheral neuropathy was not observed. The recommended doses for phase II studies are 75 to 85 mg/m2 of docetaxel on day 1 and 20 mg/m2 of vinorelbine on days 1 and 5, every 3 weeks. The treatment regimen, which included 3-day corticosteroid prophylaxis, resulted in only mild fluid retention. Responses were seen at all dose levels, with an 80% overall response rate at the higher recommended dose; the overall response rate for patients at all dose levels was 66%. A high rate of response, including a complete response, was observed in patients with liver metastases.
Combined use of positron emission tomography and volume doubling time in lung cancer screening with low-dose CT scanning.

In lung cancer screening the ability to distinguish malignant from benign nodules is a key issue. This study evaluates the ability of positron emission tomography (PET) and volume doubling time (VDT) to discriminate between benign and malignant nodules.



From the Danish Lung Cancer Screening Trial, participants with indeterminate nodules who were referred for a 3-month rescan were investigated. Resected nodules and indolent nodules (ie, stable for at least 2 years) were included. Between the initial scan and the 3-month rescan, participants were referred for PET. Uptake on PET was categorised as most likely benign to malignant (grades I-IV). VDT was calculated from volume measurements on repeated CT scans using semiautomated pulmonary nodule evaluation software. Receiver operating characteristic (ROC) analyses were used to determine the sensitivity and specificity of PET and VDT.



A total of 54 nodules were included. The prevalence of lung cancer was 37%. In the multivariate model both PET (OR 2.63, p<0.01) and VDT (OR 2.69, p<0.01) were associated with lung cancer. The sensitivities and specificities of both PET and VDT were 71% and 91%, respectively. Cut-off points for malignancy were PET>II and VDT<1 year, respectively. Combining PET and VDT resulted in a sensitivity of 90% and a specificity of 82%; ROC cut-off point was either PET or VDT indicating malignancy.



PET and VDT predict lung cancer independently of each other. The use of both PET and VDT in combination is recommended when screening for lung cancer with low-dose CT.
A Comparison of Peri-Procedural Myocardial Infarction between Paclitaxel-Coated Balloon and Drug-Eluting Stent on De Novo Coronary Lesions

This study compared the impact of paclitaxel-coated balloons (PCB) or drug eluting stents (DES) on peri-procedural myocardial infarction (PMI) on de novo coronary lesion in stable patients.



In this observational study, we compared the incidence of PMI amongst patients with single vessel de novo coronary lesions who underwent treatment with a PCB or DES. Propensity score-matching analysis was used to assemble a cohort of patients with similar baseline characteristics. PMI was classified as myocardial infarction occurring within 48 hours after percutaneous coronary intervention with a threshold of 5 x the 99th percentile upper reference limit of normal for creatine kinase-myocardial band (CK-MB) or troponin T (TnT).



One hundred four patients (52 receiving PCB and 52 receiving DES) were enrolled in this study. The peak mean values of CK-MB and TnT were significantly higher in the DES group. There was a significantly higher rate of PMI in the DES group (23.1% vs. 1.9%, p=0.002). Total occlusion of the side-branch occurred in two patients treated with DES, while no patients treated with PCB. In multivariable analysis, DES was the only independent predictor of PMI compared with PCB (odds ratio 42.85, 95% confidence interval: 3.44-533.87, p=0.004).



Treatment with a PCB on de novo coronary lesion might be associated with a significant reduction in the risk of PMI compared to DES.
Phase II and pharmacokinetic study of thalidomide in Japanese patients with relapsed/refractory multiple myeloma.

To obtain approval from the Ministry of Health, Labor and Welfare of Japan, a phase II study was conducted to assess the pharmacokinetics and pharmacodynamics of thalidomide along with its efficacy and safety in Japanese patients with multiple myeloma. Between 2005 and 2006, 42 patients were enrolled, and 37 patients met eligibility criteria. Of the 37 patients, 3 were excluded from efficacy analysis because of short duration of thalidomide administration (<4 weeks). The overall response rate was 35.3% (12/34), including partial response of 14.7% (5/34) and minimal response of 20.6% (7/34). The adverse events observed in high frequency (>40%) were leukopenia, neutropenia, drowsiness, dry mouth, and constipation. Grade 3 neutropenia was observed in nine cases. Peripheral neuropathy and eruption were observed in about one-quarter of the patients. Deep vein thrombosis was not observed. At a single oral dose of thalidomide (100 mg), the C (max) was 1.68 +/- 0.41 microg/ml, T (max) was 4.54 +/- 1.71 h, T (1/2) was 4.86 +/- 0.44 h, and AUC was 15.87 +/- 3.05 microg h/ml. Low-dose thalidomide was an effective and tolerable treatment for Japanese patients with relapsed/refractory myeloma. Leukopenia and neutropenia were the most serious adverse events. The pharmacokinetics was similar to those observed in Caucasian patients.
Heart coherence training combined with back school in patients with chronic non-specific low back pain: first pragmatic clinical results.

The aim of this study was to explore on which variables a stress reduction program based on heart coherence can enhance the effects of a back school (BS) in patients with chronic non-specific low back pain and to explore possible moderators for treatment success. A retrospective explorative design was carried out with 170 patients with chronic non-specific low back pain. 89 Patients were admitted to BS and 81 patients were selected for BS and heart coherence training (BS-HCT). Six sessions of heart coherence were provided. At T0 (baseline) and T1 (discharge), the Numeric Rating Scale for pain (NRS pain), Roland Morris Disability Questionnaire (RMDQ), Pain Disability Index (PDI) and Rand-36 were administered in both groups. Both groups improved significantly on NRS pain, RMDQ, PDI and most of the Rand-36 subscales. On physical functioning, the BS-HCT group improved significantly more than the BS group (p = 0.02) but not after Bonferroni correction. Significant moderate correlations (r = 0.39 and r = 0.48) were found between the change of heart coherence and change of PDI and RMDQ respectively, but not with other variables. Baseline characteristics were not related to change on heart coherence. Providing HCT was more effective on physical functioning compared to a BS program. Change in heart coherence was related significantly to 2 out of 12 analyses. Placebo controlled and blinded studies are needed to confirm this. Characteristics of individuals who might benefit remain unknown. Evidence of this study is considered a level C, because of its pragmatic clinical character.
Cryptochrome-1 expression: a new prognostic marker in B-cell chronic lymphocytic leukemia.

Chronic lymphocytic leukemia is an adult-onset leukemia with a heterogeneous clinical behavior. When chronic lymphocytic leukemia cases were divided on the basis of IgV(H) mutational status, widely differing clinical courses were revealed. Since IgV(H) sequencing is difficult to perform in a routine diagnostic laboratory, finding a surrogate for IgV(H) mutational status seems an important priority. In the present study, we proposed the use of Cryptochrome-1 as a new prognostic marker in early-stage chronic lymphocytic leukemia. Seventy patients (Binet stage A, without treatment) were included in the study. We correlated Cryptochrome-1 mRNA with well established prognostic markers such as IgV(H) mutations, ZAP70, LPL or CD38 expression and chromosomal abnormalities. High Cryptochrome-1 expression correlated with IgV(H) unmutated samples. In addition, Cryptochrome-1 was a valuable predictor of disease progression in early-stage chronic lymphocytic leukemia, therefore it can be introduced in clinical practice with the advantage of a simplified method of quantification.
Impact of gender on in-hospital mortality of patients with acute myocardial infarction undergoing percutaneous coronary intervention: an evaluation of the TAMIS-II data.

OBJECT
It is a matter of concern that women have higher in-hospital mortality rates than men with percutaneous coronary intervention (PCI), however, it is not yet clear whether significant gender differences exist. We studied the influence of gender on the characteristics and in-hospital mortality among patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI).



We used data from 15 acute care hospitals included in the sample from the Tokai Acute Myocardial Infarction Study II (TAMIS-II), a prospective study of all patients admitted to these hospitals from 2001 to 2003 with a diagnosis of AMI. We abstracted the baseline and procedural characteristics from detailed chart reviews which included not only physician notes but also nursing notes, and a questionnaire which included baseline characteristics, procedural course and in-hospital mortality. Multivariate analysis was performed, controlling for age and other variables which were found to be significantly different between men and women by chi-square test or unpaired t test.



A total of 566 women and 2,048 men were included in the present study.



There were gender differences in age, comorbid conditions, smoking status, body mass index, activities of daily livings, heart failure on presentation, duration of stay, angiographic data, transfer to ICU/CCU, and thrombolytic drugs. In univariate analysis, women had a higher in-hospital mortality rate than did men; however, this gender difference disappeared after adjustment for age and other variables.



Our study demonstrated that women with AMI who undergo PCI do not have a higher in-hospital mortality rate than men.
Effect of robot-assisted versus conventional body-weight-supported treadmill training on quality of life for people with multiple sclerosis.

This study describes the effect of body-weight-supported treadmill training (BWSTT) on quality of life (QoL) for multiple sclerosis (MS) patients. Thirteen individuals with MS and gait impairment randomly received two blocks of six biweekly training sessions: (1) robot-assisted BWSTT then BWSTT alone (R-T) or (2) BWSTT alone then robot-assisted BWSTT (T-R). No statistically significant differences were found between robot-assisted BWSTT and unassisted BWSTT for improving QoL outcome measures. The change in Physical Component Summary scores from baseline to the end of the 12 training sessions improved significantly more in the R-T than the T-R group. Within-participant longitudinal changes in QoL for all participants from both groups combined showed significant improvements in 5 of the 13 QoL measures. The results of this pilot study suggest that both types of BWSTT may improve QoL for people with gait dysfunction secondary to MS.
Cyberbullying victimization and mental health in adolescents and the moderating role of family dinners.

This study presents evidence that cyberbullying victimization relates to internalizing, externalizing, and substance use problems in adolescents and that the frequency of family dinners attenuate these associations.



To examine the unique association between cyberbullying victimization and adolescent mental health (after controlling differences in involvement in traditional, face-to-face bullying) and to explore the potential moderating role of family contact in this association.



This cross-sectional, observational study used survey data on 18,834 students (aged 12-18 years) from 49 schools in a Midwestern US state. Logistic regression analysis tested associations between cyberbullying victimization and the likelihood of mental health and substance use problems. Negative binomial regression analysis tested direct and synergistic contributions of cyberbullying victimization and family dinners on the rates of mental health and substance use problems.



Frequency of cyberbullying victimization during the previous 12 months; victimization by traditional (face-to-face) bullying; and perpetration of traditional bullying.



Five internalizing mental health problems (anxiety, depression, self-harm, suicide ideation, and suicide attempt), 2 externalizing problems (fighting and vandalism), and 4 substance use problems (frequent alcohol use, frequent binge drinking, prescription drug misuse, and over-the-counter drug misuse).



About one-fifth (18.6%) of the sample experienced cyberbullying during the previous 12 months. The frequency of cyberbullying positively related to all 11 internalizing, externalizing, and substance use problems (odds ratios from 2.6 [95% CI, 1.7-3.8] to 4.5 [95% CI, 3.0-6.6]). However, victimization related more closely to rates of problems in adolescents that had fewer family dinners.



Cyberbullying relates to mental health and substance use problems in adolescents, even after their involvement in face-to-face bullying is taken into account. Although correlational, these results suggest that family dinners (ie, family contact and communication) are beneficial to adolescent mental health and may help protect adolescents from the harmful consequences of cyberbullying.
Bioactive oat β-glucan reduces LDL cholesterol in Caucasians and non-Caucasians

There is increasing global acceptance that viscous soluble fibers lower serum LDL cholesterol (LDL-C), but most evidence for this comes from studies in Caucasians. To see if oat β-glucan lowers LDL-C in Caucasians and non-Caucasians we conducted a post-hoc analysis of the results of a randomized, controlled, double-blind, multi-center clinical trial whose primary aim was to determine if molecular-weight (MW) influenced the LDL-C-lowering effect of oat β-glucan.



Caucasian and non-Caucasian subjects with LDL-C-C ≥ 3.0 and ≤ 5.0 mmol/L (n = 786 screened, n = 400 ineligible, n = 19 refused, n = 367 randomized, n = 345 completed, n = 1 excluded for missing ethnicity) were randomly assigned to consume cereal containing wheat-fiber (Control, n = 74:13 Caucasian:non-Caucasian) or 3 g high-MW (3H, 2,250,000 g/mol, n = 67:19), 4 g medium-MW (4 M, 850,000 g/mol, n = 50:17), 3 g medium-MW (3M, 530,000 g/mol, n = 54:9) or 4 g low-MW (4 L, 210,000 g/mol, n = 51:12) oat β-glucan daily for 4 weeks. LDL-C after 4 weeks was influenced by baseline LDL-C (p < 0.001) and treatment (p = 0.003), but not ethnicity (p = 0.74). In all subjects, compared to control, 3 H, 4 M and 3 M reduced LDL-C significantly by 4.8 to 6.5%, but 4 L had no effect. Compared to control, the bioactive oat β-glucan treatments (3H, 4M and 3M) reduced LDL-C by a combined mean (95% CI) of 0.18 (0.06, 0.31) mmol/L (4.8%, n = 171, p = 0.004) in Caucasians, a value not significantly different from the 0.37 (0.09, 0.65) mmol/L (10.3%, n = 45, p = 0.008) reduction in non-Caucasians.



We conclude that oat β-glucan reduces LDL-C in both Caucasians and non-Caucasians; there was insufficient power to determine if the magnitude of LDL-C-lowering differed by ethnicity.
Association of CRP genetic variants with blood concentrations of C-reactive protein and colorectal cancer risk.

High blood concentrations of C-reactive protein (CRP) have been associated with elevated risk of colorectal cancer in several prospective studies including the European Prospective Investigation into Cancer and Nutrition (EPIC), but it is unknown whether these observations reflect a causal relationship. We aimed to investigate whether CRP genetic variants associated with lifelong higher CRP concentrations translate into higher colorectal cancer risk. We conducted a prospective nested case-control study within EPIC including 727 cases diagnosed between 1992 and 2003 and 727 matched controls selected according to an incidence-density sampling protocol. Baseline CRP concentrations were measured in plasma samples by a high sensitivity assay. Tagging single nucleotide polymorphisms (SNPs) in the CRP gene (rs1205, rs1800947, rs1130864, rs2808630, rs3093077) were identified via HapMap. The causal effect of CRP on colorectal cancer risk was examined in a Mendelian Randomization approach utilizing multiple CRP genetic variants as instrumental variables. The SNPs rs1205, rs1800947, rs1130864 and rs3093077 were significantly associated with CRP concentrations and were incorporated in a CRP allele score which was associated with 13% higher CRP concentrations per allele count (95% confidence interval 8-19%). Using the CRP-score as instrumental variable, genetically twofold higher CRP concentrations were associated with higher risk of colorectal cancer (odds ratio 1.74, 95% confidence interval 1.06-2.85). Similar observations were made using alternative definitions of instrumental variables. Our findings give support to the hypothesis that elevated circulating CRP may play a direct role in the etiology of colorectal cancer.
A systematic review of the effectiveness of mental health promotion interventions for young people in low and middle income countries

This systematic review provides a narrative synthesis of the evidence on the effectiveness of mental health promotion interventions for young people in low and middle-income countries (LMICs).  This paper reports on the findings for interventions promoting the positive mental health of young people (aged 6-18 years) in school and community-based settings.



Searching a range of electronic databases, 22 studies employing RCTs (N = 11) and quasi-experimental designs conducted in LMICs since 2000 were identified. Fourteen studies of school-based interventions implemented in eight LMICs were reviewed; seven of which included interventions for children living in areas of armed conflict and six interventions of multicomponent lifeskills and resilience training. Eight studies evaluating out-of-school community interventions for adolescents were identified in five countries. Using the Effective Public Health Practice Project (EPHPP) criteria, two reviewers independently assessed the quality of the evidence.



The findings from the majority of the school-based interventions are strong. Structured universal interventions for children living in conflict areas indicate generally significant positive effects on students' emotional and behavioural wellbeing, including improved self-esteem and coping skills. However, mixed results were also reported, including differential effects for gender and age groups, and two studies reported nonsignficant findings. The majority of the school-based lifeskills and resilience programmes received a moderate quality rating, with findings indicating positive effects on students' self-esteem, motivation and self-efficacy. The quality of evidence from the community-based interventions for adolescents was moderate to strong with promising findings concerning the potential of multicomponent interventions to impact on youth mental health and social wellbeing.



The review findings indicate that interventions promoting the mental health of young people can be implemented effectively in LMIC school and community settings with moderate to strong evidence of their impact on both positive and negative mental health outcomes. There is a paucity of evidence relating to interventions for younger children in LMIC primary schools. Evidence for the scaling up and sustainability of mental health promotion interventions in LMICs needs to be strengthened.
