An asthma-related quality of life instrument is unable to identify asthmatic children with major psychosocial problems

Evidence shows that psychosocial problems among children and adolescents with asthma interfere with adherence to treatment and therefore need attention in asthma care. It is unknown whether the already frequently implemented asthma-related quality of life (QoL) instruments reflect psychosocial problems in children with asthma. The aim of this study was to assess the relationship between asthma-related QoL and psychosocial problems and to determine whether an asthma-related QoL instrument is able to identify those children and adolescents with asthma with major psychosocial problems. In a multicenter study psychosocial problems (Strengths and Difficulties Questionnaire) and asthma-related QoL (Pediatric Asthma (Caregivers) Quality of Life Questionnaire) were obtained in children and adolescents with asthma aged 6–16 years and their caregivers. A total of 339 children and adolescents (response rate 95%) from four pediatric outpatient clinics in the Netherlands with doctor-diagnosed asthma participated. Of the caregivers, 43% reported major or minor psychosocial problems of their child or adolescent which is two times more than in the reference group, whereas the percentage of adolescents reporting psychosocial problems was comparable to a reference population. Adolescents and caregivers reported few impairments in asthma-related QoL (median score between 6.2 and 7.0). However, an optimal asthma-related QoL did not rule out major psychosocial problems: 10% of the adolescents with an optimal asthma-related QoL score reported major psychosocial problems. And in one out of seven children with an optimal caregiver’s asthma-related QoL score, major psychosocial problems were reported. The prevalence of psychosocial problems in children and adolescents with asthma is considerable. Assessment of asthma-related QoL alone is insufficient to identify those children with major psychosocial problems. We recommend the implementation of psychosocial screening, besides assessment of asthma-related QoL, in routine pediatric asthma care, to improve asthma management.
Phase II study of NK313 in malignant lymphomas: an NK313 Malignant Lymphoma Study Group trial

Liblomycin (NK313) is a bleomycin analog that has proved to be associated with less pulmonary toxicity and with more potent antitumor activity than bleomycin in animal tumors. In a phase I study, pulmonary toxicity was not observed, whereas myelosuppression was the dose-limiting factor. The maximum tolerated dose was 140 mg/m2 given once a week for 4 weeks. In the present phase II study, patients with malignant lymphomas received liblomycin at 80 or 100 mg/m2 by intravenous infusion over 15 min once a week for 4 weeks. A total of 39 patients were entered, and 31 [4 with Hodgkin's disease (HD) and 27 with non-Hodgkin's lymphoma (NHL)] were evaluable. The median age of the patients was 52 years (range, 22–74 years), and their performance status ranged from 0 to 3. In all, 28 of the patients had a history of intensive anticancer chemotherapy. Responses were evaluated according to WHO criteria. We obtained 1 complete remission and 9 partial remissions (PRs), for an overall response rate of 37%, in the 27 patients with NHL, whereas 1 PR was achieved in the 4 patients with HD. In all, 9 PRs (32.1%) were obtained in patients who has been exposed to prior chemotherapy, including 4 PRs (33.3%) in 12 patients who had previously been treated with bleomycin. Myelosuppression and nausea and vomting were the major toxicities, which occurred in about 50% of the patients, and myelosuppression was severe in two patients treated at a dose of 100 mg/m2. We concluded that liblomycin demonstrated significant antitumor activity against malignant lymphomas.
Lung function in adult patients with cystic fibrosis after using the eFlow® rapid for one year

The new generation nebuliser PARI eFlow® rapid allows a highly efficient aerosol delivery at reduced inhalation time. However, lung function data during long-term use of this device are not available until now.



70 clinically stable adult cystic fibrosis patients participated in this observation study. Lung function tests were performed prospectively 12 weeks after and again 9 to 12 months after switching the inhalation device from a conventional jet nebulizer to the PARI eFlow® rapid. Lung function data were collected retrospectively from the visits 1 year as well as 12 weeks prior to the switch-over. Lung function data for all time points were only available for 59 patients. Treatment time and patient's satification were recorded for both conventional and new nebuliser in all 70 patients.



After 1 year of inhalation with eFlow® rapid, the mean change in FEV1% was - 1.4% (n = 59 patients). The decrease in FEV1 was smaller than the change in FEV1 after 1 year of inhalation with the conventional jet nebuliser (control period, -3.1%), although this difference was not statistically significant. The same effect was seen in MEF25(%) (-2.6% with conventional nebuliser compared to -1.6% after eFlow® rapid). Concerning the FVC, there was a greater improvement after 1 year of inhalation with the eFlow® rapid than with the jet nebuliser (+ 2.9% vs. +1.1%). For PEF%, there was an increase during the control period, whereas after inhalation with eFlow® rapid there was a decrease (+1.1% vs. -2.9%). All changes were not significantly different. The eFlow® rapid reduced total daily inhalation time by two-thirds (conventional nebuliser: 31.1 min/day; eFlow® rapid: 10.2 min/day, n = 70 patients).



Inhalation with the new nebuliser eFlow rapid does not alter FEV1, FVC or PEF significantly after 1 year of inhalation. The treatment time could be reduced significantly by the eFlow® rapid.
Suspected multiple sclerosis - what to do? Evaluation of a patient information leaflet.

Parallel to the establishment of early treatments in multiple sclerosis (MS), new diagnostic criteria have made an earlier diagnosis possible. While there is ongoing discussion about possible benign courses and only partial effective treatments, there have been no attempts today to facilitate shared decision making on diagnostic testing between patients with suspected MS and their physicians.



This study describes the development and validation process of a leaflet to be presented to people with suspected MS to engage them in a diagnostic decision-making process.



After a qualitative study showing acceptability among five patients, the leaflet was presented to a retrospective cohort (n = 87 of which 70 replied)) of patients being diagnosed within the last 2 years as well to a prospective cohort of n = 51 patients with symptoms suggestive of MS.



Approximately 70% of patients in the prospective as well as in the retrospective cohort wanted to be informed about a possible MS before testing, whereas 10% did not. The leaflet did not seem to elicit anxieties. The attitude to undergo diagnostic testing was not influenced by the leaflet, which can be explained by the nonexperimental design of the study.



Taken together, our findings demonstrate that early information about possible MS is warranted by patients and does not show negative side effects. Further studies on evidence-based patient information in early MS seem necessary.
Reductions in qEEG slowing over 1 year and after treatment with Cerebrolysin in patients with moderate–severe traumatic brain injury

Changes in quantitative EEG (qEEG) recordings over a 1-year period and the effects of Cerebrolysin (Cere) on qEEG slowing and cognitive performance were investigated in postacute moderate–severe traumatic brain injury (TBI) patients. Time-related changes in qEEG activity frequency bands (increases of alpha and beta, and reductions of theta and delta relative power) and in qEEG slowing (reduction of EEG power ratio) were statistically significant in patients with a disease progress of less than 2 years at baseline, but not in those patients having a longer disease progress time. Slowing of qEEG activity was also found to be significantly reduced in TBI patients after 1 month of treatment with Cere and 3 months later. Therefore, Cere seems to accelerate the time-related reduction of qEEG slowing occurring in untreated patients. The decrease of qEEG slowing induced by Cere correlated with the improvement of attention and working memory. Results of this exploratory study suggest that Cere might improve the functional recovery after brain injury and encourage the conduction of further controlled clinical trials.
Evidence of social network influence on multiple HIV risk behaviors and normative beliefs among young Tanzanian men.

Research on network-level influences on HIV risk behaviors among young men in sub-Saharan Africa is severely lacking. One significant gap in the literature that may provide direction for future research with this population is understanding the degree to which various HIV risk behaviors and normative beliefs cluster within men's social networks. Such research may help us understand which HIV-related norms and behaviors have the greatest potential to be changed through social influence. Additionally, few network-based studies have described the structure of social networks of young men in sub-Saharan Africa. Understanding the structure of men's peer networks may motivate future research examining the ways in which network structures shape the spread of information, adoption of norms, and diffusion of behaviors. We contribute to filling these gaps by using social network analysis and multilevel modeling to describe a unique dataset of mostly young men (n = 1249 men and 242 women) nested within 59 urban social networks in Dar es Salaam, Tanzania. We examine the means, ranges, and clustering of men's HIV-related normative beliefs and behaviors. Networks in this urban setting varied substantially in both composition and structure and a large proportion of men engaged in risky behaviors including inconsistent condom use, sexual partner concurrency, and intimate partner violence perpetration. We found significant clustering of normative beliefs and risk behaviors within these men's social networks. Specifically, network membership explained between 5.78 and 7.17% of variance in men's normative beliefs and between 1.93 and 15.79% of variance in risk behaviors. Our results suggest that social networks are important socialization sites for young men and may influence the adoption of norms and behaviors. We conclude by calling for more research on men's social networks in Sub-Saharan Africa and map out several areas of future inquiry.
An updated natural history model of cervical cancer: derivation of model parameters.

Mathematical models of cervical cancer have been widely used to evaluate the comparative effectiveness and cost-effectiveness of preventive strategies. Major advances in the understanding of cervical carcinogenesis motivate the creation of a new disease paradigm in such models. To keep pace with the most recent evidence, we updated a previously developed microsimulation model of human papillomavirus (HPV) infection and cervical cancer to reflect 1) a shift towards health states based on HPV rather than poorly reproducible histological diagnoses and 2) HPV clearance and progression to precancer as a function of infection duration and genotype, as derived from the control arm of the Costa Rica Vaccine Trial (2004-2010). The model was calibrated leveraging empirical data from the New Mexico Surveillance, Epidemiology, and End Results Registry (1980-1999) and a state-of-the-art cervical cancer screening registry in New Mexico (2007-2009). The calibrated model had good correspondence with data on genotype- and age-specific HPV prevalence, genotype frequency in precancer and cancer, and age-specific cancer incidence. We present this model in response to a call for new natural history models of cervical cancer intended for decision analysis and economic evaluation at a time when global cervical cancer prevention policy continues to evolve and evidence of the long-term health effects of cervical interventions remains critical.
Conjugated equine estrogens and colorectal cancer incidence and survival: the Women's Health Initiative randomized clinical trial.

In separate Women's Health Initiative randomized trials, combined hormone therapy with estrogen plus progestin reduced colorectal cancer incidence but estrogen alone in women with hysterectomy did not. We now analyze features of the colorectal cancers that developed and examine the survival of women following colorectal cancer diagnosis in the latter trial.



10,739 postmenopausal women who were 50 to 79 years of age and had undergone hysterectomy were randomized to conjugated equine estrogens (0.625 mg/d) or matching placebo. Colorectal cancer incidence was a component of the monitoring global index of the study but was not a primary study endpoint. Colorectal cancers were verified by central medical record and pathology report review. Bowel exam frequency was not protocol defined, but information on their use was collected.



After a median 7.1 years, there were 58 invasive colorectal cancers in the hormone group and 53 in the placebo group [hazard ratio, 1.12; 95% confidence interval (95% CI), 0.77-1.63]. Tumor size, stage, and grade were comparable in the two randomization groups. Bowel exam frequency was also comparable in the two groups. The cumulative mortality following colorectal cancer diagnosis among women in the conjugated equine estrogen group was 34% compared with 30% in the placebo group (hazard ratio, 1.34; 95% CI, 0.58-3.19).



In contrast to the preponderance of observational studies, conjugated equine estrogens in a randomized clinical trial did not reduce colorectal cancer incidence nor improve survival after diagnosis.
Does Vascular Calcification Accelerate Inflammation?: A Substudy of the dal-PLAQUE Trial.

Atherosclerosis is an inflammatory condition with calcification apparent late in the disease process. The extent and progression of coronary calcification predict cardiovascular events. Relatively little is known about noncoronary vascular calcification.



This study investigated noncoronary vascular calcification and its influence on changes in vascular inflammation.



A total of 130 participants in the dal-PLAQUE (Safety and efficacy of dalcetrapib on atherosclerotic disease using novel non-invasive multimodality imaging) study underwent fluorodeoxyglucose positron emission tomography/computed tomography at entry and at 6 months. Calcification of the ascending aorta, arch, carotid, and coronary arteries was quantified. Cardiovascular risk factors were related to arterial calcification. The influences of baseline calcification and drug therapy (dalcetrapib vs. placebo) on progression of calcification were determined. Finally, baseline calcification was related to changes in vascular inflammation.



Age >65 years old was consistently associated with higher baseline calcium scores. Arch calcification trended to progress more in those with calcification at baseline (p = 0.055). There were no significant differences between progression of vascular calcification with dalcetrapib compared to that with placebo. Average carotid target-to-background ratio indexes declined over 6 months if carotid calcium was absent (single hottest slice [p = 0.037], mean of maximum target-to-background ratio [p = 0.010], and mean most diseased segment [p < 0.001]), but did not significantly change if calcification was present at baseline.



Across multiple arterial regions, higher age is consistently associated with higher calcium scores. The presence of vascular calcification at baseline is associated with progressive calcification; in the carotid arteries, calcification appears to influence vascular inflammation. Dalcetrapib therapy did not affect vascular calcification.
Effect of Body Mass Index on Left Ventricular Mass in Career Male Firefighters

Left ventricular (LV) mass is a strong predictor of cardiovascular disease (CVD) events; increased LV mass is common among US firefighters and plays a major role in firefighter sudden cardiac death. We aim to identify significant predictors of LV mass among firefighters. Cross-sectional study of 400 career male firefighters selected by an enriched randomization strategy. Weighted analyses were performed based on the total number of risk factors per subject with inverse probability weighting. LV mass was assessed by echocardiography (ECHO) and cardiac magnetic resonance, and normalized (indexed) for height. CVD risk parameters included vital signs at rest, body mass index (BMI)-defined obesity, obstructive sleep apnea risk, low cardiorespiratory fitness, and physical activity. Linear regression models were performed. In multivariate analyses, BMI was the only consistent significant independent predictor of LV mass indexes (all, p <0.001). A 1-unit decrease in BMI was associated with 1-unit (g/m1.7) reduction of LV mass/height1.7 after adjustment for age, obstructive sleep apnea risk, and cardiorespiratory fitness. In conclusion, after height-indexing ECHO-measured and cardiac magnetic resonance-measured LV mass, BMI was found to be a major driver of LV mass among firefighters. Our findings taken together with previous research suggest that reducing obesity will improve CVD risk profiles and decrease on-duty CVD and sudden cardiac death events in the fire service. Our results may also support targeted noninvasive screening for LV hypertrophy with ECHO among obese firefighters.
Nonablative allogeneic hematopoietic transplantation as adoptive immunotherapy for indolent lymphoma: low incidence of toxicity, acute graft-versus-host disease, and treatment-related mortality.

This study investigated the use of a nonablative conditioning regimen to decrease toxicity and achieve engraftment of an allogeneic blood stem cell transplant, allowing a graft-versus-malignancy effect to occur. All patients had follicular or small cell lymphocytic lymphoma after relapse from a prior response to conventional chemotherapy. Patients received a preparative regimen of fludarabine (25 mg/m(2) given daily for 5 days or 30 mg/m(2) daily for 3 days) and intravenous cyclophosphamide (1 g/m(2) given daily for 2 days or 750 mg/m(2) daily for 3 days). Nine patients received rituximab in addition to the chemotherapy. Tacrolimus and methotrexate were used for graft-versus-host disease (GVHD) prophylaxis. Twenty patients were studied; their median age was 51 years. Twelve were in complete remission (CR) at transplantation. All patients achieved engraftment of donor cells. The median number of days with severe neutropenia was 6. Only 2 patients required more than one platelet transfusion. The cumulative incidence of acute grade II to IV GVHD was 20%. Only one patient developed acute GVHD of greater than grade II. All patients achieved CR. None have had a relapse of disease, with a median follow-up period of 21 months. The actuarial probability of being alive and in remission at 2 years was 84% (95% confidence interval, 57%-94%). Nonablative chemotherapy with fludarabine/cyclophosphamide followed by allogeneic stem cell transplantation is a promising therapy for indolent lymphoma with minimal toxicity and myelosuppression. Further studies are warranted to compare nonablative allogeneic hematopoietic transplantation with alternative treatment strategies.
Nutritional education and carbohydrate counting in children with type 1 diabetes treated with continuous subcutaneous insulin infusion: the effects on dietary habits, body composition and glycometabolic control

Carbohydrate counting (CHC) in combination with nutritional education has been used to optimize the insulin dose in patients with type 1 diabetes (T1D). The aim of this study was to test the impact of CHC and nutritional education on changes in dietary habits, body composition and body fat distribution in children with T1D treated with insulin pumps (CSII). Twenty-five children with T1D and CSII were recruited and valuated at baseline and after 18 months of follow-up. They were trained in CHC and following standard nutrition education program (based on American Diabetes Association and International Society of Pediatric and Adolescent Diabetes guidelines); clinical, biochemical and nutritional variables were measured. In the total population, body composition, body fat distribution and biochemical variables did not change, at follow-up; HbA1c was significantly reduced (8.50 ± 0.77 vs 7.92 ± 0.74 %; p < 0.001) without changing insulin/kg/day requirement. In the sub-group of patients with a significant HbA1c reduction (ΔHbA1c ≥ 0.5 %, n = 12), the carbohydrate (CHO) intake was significantly higher at follow-up (53.0 ± 4.0 vs 57.6 ± 2.5 %; p < 0.01); on the contrary, fat (31.3 ± 3.6 vs 28.5 ± 1.6 %; p < 0.05) and protein intake (15.4 ± 1.8 vs 13.3 ± 1.6 %; p < 0.01) significantly decreased. Patients without a significant HbA1c reduction did not show any difference. CHC, in combination with nutritional education, does not affect dietary habits, body composition and body fat distribution in children with T1D treated with CSII. Moreover, the sub-group of subjects showing a significant improvement in glycometabolic control reported an increase in CHO intake and a reduction in fat and protein intake.
Decision aids for respite service choices by carers of people with dementia: development and pilot RCT

Decision aids are often used to assist individuals confronted with a diagnosis of a serious illness to make decisions about treatment options. However, they are rarely utilised to help those with chronic or age related conditions to make decisions about care services. Decision aids should also be useful for carers of people with decreased decisional capacity. These carers' choices must balance health outcomes for themselves and for salient others with relational and value-based concerns, while relying on information from health professionals. This paper reports on a study that both developed and pilot tested a decision aid aimed at assisting carers to make evaluative judgements of community services, particularly respite care.



A mixed method sequential study, involving qualitative development and a pilot randomised controlled trial, was conducted in Tasmania, Australia. We undertook 13 semi-structured interviews and three focus groups to inform the development of the decision aid. For the randomised control trial we randomly assigned 31 carers of people with dementia to either receive the service decision aid at the start or end of the study. The primary outcome was measured by comparing the difference in carer burden between the two groups three months after the intervention group received the decision aid. Pilot data was collected from carers using interviewer-administered questionnaires at the commencement of the project, two weeks and 12 weeks later.



The qualitative data strongly suggest that the intervention provides carers with needed decision support. Most carers felt that the decision aid was useful. The trial data demonstrated that, using the mean change between baseline and three month follow-up, the intervention group had less increase in burden, a decrease in decisional conflict and increased knowledge compared to control group participants.



While these results must be interpreted with caution due to the small sample size, all intervention results trend in a direction that is beneficial for carers and their decisional ability. Mixed method data suggest the decision aid provides decisional support that carers do not otherwise receive. Decision aids may prove useful in a community health services context.
