Journal article (peer-reviewed)abstract
- Background: We assessed if histidine-rich-protein-2 (HRP2) based rapid diagnostic test (RDT) remains an efficient tool for Plasmodium falciparum case detection among fever patients in Zanzibar and if primary health care workers continue to adhere to RDT results in the new epidemiological context of low malaria transmission. Further, we evaluated the performance of RDT within the newly adopted integrated management of childhood illness (IMCI) algorithm in Zanzibar. Methods and Findings: We enrolled 3890 patients aged >= 2 months with uncomplicated febrile illness in this health facility based observational study conducted in 12 primary health care facilities in Zanzibar, between May-July 2010. One patient had an inconclusive RDT result. Overall 121/3889 (3.1%) patients were RDT positive. The highest RDT positivity rate, 32/528 (6.1%), was found in children aged 5-14 years. RDT sensitivity and specificity against PCR was 76.5% (95% CI 69.0-83.9%) and 99.9% (95% CI 99.7-100%), and against blood smear microscopy 78.6% (95% CI 70.8-85.1%) and 99.7% (95% CI 99.699.9%), respectively. All RDT positive, but only 3/3768 RDT negative patients received anti-malarial treatment. Adherence to RDT results was thus 3887/3889 (99.9%). RDT performed well in the IMCI algorithm with equally high adherence among children,5 years as compared with other age groups. Conclusions: The sensitivity of HRP-2 based RDT in the hands of health care workers compared with both PCR and microscopy for P. falciparum case detection was relatively low, whereas adherence to test results with anti-malarial treatment was excellent. Moreover, the results provide evidence that RDT can be reliably integrated in IMCI as a tool for improved childhood fever management. However, the relatively low RDT sensitivity highlights the need for improved quality control of RDT use in primary health care facilities, but also for more sensitive point-of-care malaria diagnostic tools in the new epidemiological context of low malaria transmission in Zanzibar.

Change in kinesiophobia and its relation to activity limitation after multidisciplinary rehabilitation in patients with chronic back pain
- 2012

Journal article (peer-reviewed)abstract
- Purpose: To explore the change in kinesiophobia in relation to activity limitation after a multidisciplinary rehabilitation programme in patients with chronic back pain. Method: A prospective cohort study was made including 265 patients. Data were collected at baseline, after rehabilitation, and at 6-months follow-up. Outcome measures were the Tampa Scale for kinesiophobia (TSK) and the disability rating index (DRI). The smallest detectable change (SDC) in TSK was set to 8 scores. Relationships between kinesiophobia and activity limitation/physical ability were explored with regard to subgroups with high, medium and low baseline TSK scores, and for those patients who did or did not reach the SDC in TSK. Results: Improvements in TSK showed high effect sizes in the groups with high and medium baseline TSK scores. Improvements in DRI showed medium effect sizes in all three TSK subgroups. One third of the patients reached the SDC in TSK, and this group also improved significantly more in DRI. The correlation between change in TSK and change in DRI was low. Half of the patients with high TSK score at baseline remained having high DRI at follow-up. Conclusions: Improvement in physical ability was not related to the initial degree of kinesiophobia but to the SDC in TSK. To prevent patients with high kinesiophobia from preserving high activity limitations, it might be useful to include targeted treatment of kinesiophobia.

Effect of multilayer high-compression bandaging on ankle range of motion and oxygen cost of walking

Journal article (peer-reviewed)abstract
- To evaluate the effects of multilayer high-compression bandaging on ankle range of motion, oxygen consumption and subjective walking ability in healthy subjects. Method A volunteer sample of 22 healthy subjects (10 women and 12 men; aged 67 [63–83] years) were studied. The intervention included treadmill-walking at self-selected speed with and without multilayer high-compression bandaging (Proforeº), randomly selected. The primary outcome variables were ankle range of motion, oxygen consumption and subjective walking ability. Results Total ankle range of motion decreased 4% with compression. No change in oxygen cost of walking was observed. Less than half the subjects reported that walking-shoe comfort or walking distance was negatively affected. Conclusion Ankle range of motion decreased with compression but could probably be counteracted with a regular exercise programme. There were no indications that walking with compression was more exhausting than walking without. Appropriate walking shoes could seem important to secure gait efficiency when using compression garments.
