Effectiveness of behavioral interventions and behavior change techniques for reducing soft drink intake in disadvantaged adolescents: A systematic review and meta-analysis.

Reducing sugar-sweetened beverage (SSB) intake is an important dietary target, especially among socioeconomically disadvantaged ethnic minority adolescents. This review and meta-analysis evaluated the effectiveness of behavioural interventions aiming to reduce SSB intake in socioeconomically disadvantaged ethnic minority adolescents and examined which behaviour change techniques (BCTs) were most effective. A systematic search was conducted using the PRISMA criteria. Quality assessments were done using the Cochrane criteria. In a narrative synthesis, studies were divided into effective and non-effective, and relative effectiveness ratios of individual BCTs were calculated. Pooled standardized mean differences (SMDs) and their 95% confidence intervals were estimated with random-effects models using cluster robust methods. Twenty-two studies were included in the qualitative synthesis. A meta-analysis (n = 19) revealed no significant between-group differences in reduction of SSB intake. Five self-regulatory BCTs had an effectiveness ratio >50%: feedback, goal-setting, action planning, self-monitoring and problem-solving/barrier identification. The risk of bias assessments were judged to be moderate to high risk for randomized controlled trials (RCTs) studies and low to moderate for pre-post studies. There was no indication of publication bias. In conclusion, self-regulatory BCTs may be effective components to change SSB behaviour. However, high-quality research is needed to evaluate the effectiveness of behavioural interventions and identify BCTs effective for reducing SSB intake among disadvantaged adolescents with ethnic minority backgrounds.

Midterm results of autologous saphenous vein and ePTFE pre-cuffed bypass surgery in peripheral arterial occlusive disease.

INTRODUCTION: The graft of choice in lower limb bypass surgery is the autologous saphenous vein (ASV). However, a prosthetic graft is needed in the absence of an ASV. In such situations, we used an expanded polytetrafluoroethylene (ePTFE) pre-cuffed Dynaflo graft as supragenicular bypass or Distaflo graft as infragenicular or femorocrural bypass. In respect to the expanding possibilities of percutaneous transluminal angioplasty (PTA), the indication for bypass surgery moved toward patients with advanced stages of peripheral arterial occlusive disease. For this reason, this study analyzed the current performances of these ePTFE grafts and ASV grafts with special attention to limb salvage. METHODS: In a retrospective study all patients who underwent peripheral bypass surgery between 2004 and 2008 were included. Kaplan-Meier curves were used to express primary patency, secondary patency, and limb salvage rates at 1 and 3 years. Log-rank tests were performed to compare graft types. RESULTS: A total of 272 grafts (ePTFE/ASV: 110/162) were performed in lower limb bypass surgery. The mean follow-up was 20.3 months. The secondary 3-year patency rates were for (n=78) supragenicular grafts (ePTFE/ASV: 45%/94%)*, for (n=124) infragenicular grafts (24%/74%), and 70 for femorocrural grafts (26%/52%). Limb salvage after 3 years was 59% in the ePTFE group versus 78% in the ASV group (P < .05). CONCLUSION: In the current population of vascular patients where no PTA is possible and a peripheral bypass is necessary, the ASV remains the graft of first choice. However, the pre-cuffed ePTFE graft is a good alternative, especially in cases of critical limb ischemia, in respect to an acceptable limb salvage rate.

Ruptured abdominal aortic aneurysm: endovascular or open approach in a Dutch general hospital.

AIM: We compared the outcomes of 56 patients with a ruptured abdominal aortic aneurysm (RAAA) who underwent either open repair or emergency endovascular aneurysm repair (eEVAR) in a general hospital. It seems feasible that the availability of eEVAR for treatment of RAAA could lead to a decrease in hospital mortality. METHODS: We analyzed all admitted patients with a RAAA, between January 2006 and April 2008, eEVAR is compared to open repair. We studied 30 days mortality, intensive care unit stay, hospital stay, total blood loss and complications. RESULTS: Fifteen eEVAR procedures (26.8%) were performed. Mortality in the eEVAR-group was 26%, in the open repair-group 46%. Mean intensive care unit stay was 3.9 days and 4.8 days in the eEVAR-group and open repair-group, respectively. Mean hospital stay was 13 days and 10.5 days. The average blood loss was 210cc and 2760cc. The amount of blood products for transfusion was significantly higher in the open repair. Overall complication rate was not significantly different in both treatment groups. CONCLUSION: Treatment in a Dutch general hospital of a RAAA with an eEVAR procedure has a lower mortality in comparison to the open repair. Therefore, whenever possible the eEVAR is the preferred treatment method.

Evaluation of A-V impulse technology as a treatment for oedema following polytetrafluoroethylene femoropopliteal surgery in a randomised controlled trial.

OBJECTIVE: To investigate the efficacy of A-V impulse technology (A-V) for oedema prevention and treatment following PTFE femoropopliteal surgery. DESIGN: Prospective randomized clinical trial. MATERIALS: 36 patients undergoing PTFE femoropopliteal bypass reconstructions, either being treated postoperatively with a compression stocking (CS) (Group-1, n = 19) or with A-V (Group-2, n = 17). METHODS: Patients in treatment group-1 used a CS postoperatively during 1 week day and night, patients in group-2 were treated with A-V postoperatively at night during one week. The lower leg circumference was measured preoperatively and at five postoperative time points. RESULTS: Limb circumference has increased postoperatively on day 1 (CS 1.5%/A-V 1.4%), on day 4 (5.7%/6.3%), on day 7 (6.6%/6.1%), on day 14 (7.9%/7.7%) and on day 90 (5.8%/5.2%). Differences between treatment groups were not significant. A re-operation gives a significant 3.9% increase in circumference as compared to a first operation (95% CI: 1.5-6.4%; p = 0.002). CONCLUSION: No significant differences were found in the extent of developed edema between the groups following PTFE femoropopliteal bypass surgery. A redo peripheral bypass operation results in significantly more postoperative oedema than a first-time performed bypass operation.

Endovascular aneurysm repair with Zenith graft. Complications caused by leg extensions.

AIM: A large amount of Zenith endovascular stent complications is due to problems with the leg extensions. This kind of complication has never been reported in literature. The aim of this study was to monitor the complications of endovascular abdominal aneurysm repair (EVAR) performed with the Zenith endovascular graft occurred in the Amphia Ziekenhuis in Breda to see how many recurrences were due to leg extension. METHODS: The study enrolled all patients (N.=66) treated with the Zenith endograft in the period between October 2000 and September 2006. Mortality, complications and the number of reinterventions were analysed. Average age of the patients was 73.4 years, average follow-up was 24.5 months and average aneurysm size was 61.5 mm. Radiologic follow-up was performed by computed tomography scans and X-rays. RESULTS: Postoperative mortality rate was 0%. The overall mortality rate during follow-up was 3%. Ten patients required a total number of 12 reinterventions (15%). The average time for reintervention was 10 months after the primary operation. Mortality, complication and reintervention rates were comparable with those reported in the literature, but 75% of these reinterventions were related to the leg extensions. CONCLUSION: Authors observed that nine out of 12 complications which required reintervention were due to problems with one of the leg extensions. This is the first study that specifies clearly the percentage of problems with leg extensions in EVAR (75%). When placing a Zenith endovascular graft extra attention should be paid to optimal placement of the leg extensions.

[Abdominal pain as a symptom of a late complication following endovascular treatment of an aneurysm of the abdominal aorta]. / Abdominale pijn als symptoom van een late complicatie na endovasculaire behandeling van een aneurysma van de abdominale aorta.

A 72-year-old man presented with progressive pain in the left lower abdomen thought to be due to diverticulitis of the colon. Antimicrobial therapy had not reduced the symptoms. Four years before, during an endovascular procedure, the patient had been given a stent because of an abdominal aortic aneurysm (AAA). A CT scan showed a large retroperitoneal haematoma on the left side and an increased diameter of the AAA of 8.5 cm. X-rays showed a gap between the endovascular stent and the left iliac leg of the endoprosthesis. Due to the space between the two grafts, there was retroperitoneal leakage ofblood. In endovascular surgery this life-threatening situation is called a type III endoleak. The patient was operated immediately using the endovascular technique. Through the left femoral artery a new coated stent was positioned over the gap, which led to rapid recovery of the patient. Patients with abdominal pain and a history of a vascular endoprosthesis should be given a CT scan and plain radiography to exclude an endoleak.

Economic analysis of micafungin versus liposomal amphotericin B for treatment of candidaemia and invasive candidiasis in Germany.

OBJECTIVE: To investigate the economic impact of micafungin (MICA) for treatment of invasive candidiasis and candidaemia (systemic Candida infections), a health economic analysis was conducted comparing MICA with liposomal amphotericin B (L-AMB). RESEARCH DESIGN AND METHODS: The model was based on a phase III, randomised, double-blind, clinical trial which compared MICA with L-AMB. The model entailed a period of 14-20 weeks starting from initiation of treatment and was analysed from a German hospital perspective. MAIN OUTCOME MEASURES: The main outcome measures were defined as the percentage of patients achieving clinical and mycological response after initial treatment and who were alive at the end of the study (EOS), and the total treatment-associated costs over the study period. RESULTS: The health economic analysis shows that with MICA, 52.9% of patients are successfully treated and were alive at EOS compared to 49.1% for L-AMB. In addition, MICA has, on average, lower treatment-associated costs than L-AMB with euro43 243 and euro49 216 per patient, respectively. Because the costs are lower and the effectiveness is higher for MICA in comparison with L-AMB, MICA is more cost-effective than L-AMB. However, the results of the probabilistic sensitivity analysis show that the differences cannot be considered significant due to a large variance, although MICA remained the most cost-effective option throughout the one-way sensitivity analyses. CONCLUSIONS: The lower costs and higher effectiveness reported for MICA versus L-AMB in this analysis indicate that MICA may be a more cost-effective therapy in the treatment of invasive candidiasis and candidaemia when compared with L-AMB.

The incidences of and consultation rate for lower extremity complaints in general practice.

OBJECTIVE: To estimate the incidence and consultation rate of lower extremity complaints in general practice. METHODS: Data were obtained from the Second Dutch National Survey of General Practice, in which 195 general practitioners (GPs) in 104 practices recorded all contacts with patients during 12 consecutive months in computerised patient records. GPs classified the symptoms and diagnosis for each patient at each consultation according to the International Classification of Primary Care (ICPC). Incidence densities and consultation rates for different complaints were calculated. RESULTS: During the registration period 63.2 GP consultations per 1000 person-years were attributable to a new complaint of the lower extremities. Highest incidence densities were seen for knee complaints: 21.4 per 1000 person-years for women and 22.8 per 1000 person-years for men. The incidence of most lower extremity complaints was higher for women than for men and higher in older age. CONCLUSIONS: Both incidences of and consultation rates for lower extremity complaints are substantial in general practice. This implies a considerable impact on the workload of the GP.

Course and prognosis of elbow complaints: a cohort study in general practice.

OBJECTIVE: To describe the course of new episodes of elbow complaints in general practice, and to identify predictors of short term and long term outcome in terms of pain intensity and functional disability. METHODS: 181 patients with elbow complaints filled in questionnaires at baseline and at 3, 6, and 12 months of follow up. Baseline scores of pain and disability, characteristics of the complaint, sociodemographic and psychosocial factors, physical activity, general health, and comorbidity were investigated as possible predictors of outcome. Outcome measures were analysed separately using multiple regression analyses. RESULTS: 13% of the patients reported recovery at the 3 month follow up and 34% at 12 months. Irrespective of outcome and length of follow up, a longer duration of the complaint before consulting the general practitioner, having musculoskeletal comorbidity, and using "retreating" as coping style increased the likelihood of an unfavourable outcome. Less social support was associated with an unfavourable outcome at 3 months, and having a history of elbow complaints and using "worrying" as coping style were associated with an unfavourable outcome at 12 months. The explained variance of the models ranged from 46% to 49%. CONCLUSIONS: Recovery of patients with elbow complaints in general practice was poor. Besides characteristic of the complaint, passive coping and less social support were related to a worse prognosis. The results of this study may help general practitioners to provide patients with more accurate information about their prognosis.

Incidence and prevalence of complaints of the neck and upper extremity in general practice.

OBJECTIVE: To study the incidence and prevalence of neck and upper extremity musculoskeletal complaints in Dutch general practice. METHODS: Data were obtained from the second Dutch national survey of general practice. In all, 195 general practitioners (GPs) from 104 practices across the Netherlands recorded all contacts with patients during 12 consecutive months. Incidence densities and consultation rates were calculated. RESULTS: The total number of contacts during the registration period of one year was 1 524 470. The most commonly reported complaint was neck symptoms (incidence 23.1 per 1000 person-years), followed by shoulder symptoms (incidence 19.0 per 1000 person-years). Sixty six GP consultations per 1000 person-years were attributable to a new complaint or new episode of complaint of the neck or upper extremity (incidence density). In all, the GPs were consulted 147 times per 1000 registered persons for complaints of the neck or upper extremity. For most complaints the incidence densities and consultation rates were higher for women than for men. CONCLUSIONS: Neck and upper extremity symptoms are common in Dutch general practice. The GP is consulted approximately seven times each week for a complaint relating to the neck or upper extremity; of these, three are new complaints or new episodes. Attention should be paid to training GPs to deal with neck and upper limb complaints, and to research on the prognosis and treatment of these common complaints in primary care.
