Background and aims Evaluating status in patients with motor fluctuations is complex and occasional observations/measurements do not give an adequate picture as to the time spent in different states. We developed a test battery to assess advanced Parkinson patients' status consisting of diary assessments and motor tests. This battery was constructed and implemented on a handheld computer with built-in mobile communication. In fluctuating patients, it should typically be used several times daily in the home environment, over periods of about one week. The aim of this battery is to provide status information in order to evaluate treatment effects in clinical practice and research, follow up treatments and disease progression and predict outcome to optimize treatment strategy. Methods Selection of diary questions was based on a previous study with Duodopa® (DIREQT). Tapping tests (with and without visual cueing) and a spiral drawing test were added. Rapid prototyping was used in development of the user interface. An evaluation with two pilot patients was performed before and after receiving new treatments for advanced disease (one received Duodopa® and one received DBS). Speed and proportion missed taps were calculated for the tapping tests and entropy of the radial drawing velocity was calculated for the spiral tests. Test variables were evaluated using non-parametric statistics. Results Post-treatment improvement was detected in both patients in many of the test variables. Conclusions Although validation work remains, preliminary results are promising and the test battery is currently being evaluated in a long-term health economics study with Duodopa® (DAPHNE).

I ett internationellt perspektiv har Sverige hög amningsfrekvens, men under 2000-talet har amningsfrekvensen sjunkit och stora regionala skillnader ses. Kvinnorna rekommenderas att helamma sex månader. Mödravårdcentralen (MVC) informerar om bröstmjölkens hälsoeffekter som till exempel att bröstmjölken skyddar barn mot allergier. Forskning visar att överviktiga och feta kvinnor har kortare amningsduration, men få studier behandlar svenska förhållanden. Syfte: Syfte med fördjupningsarbetet är att studera samband mellan mammans BMI relaterat till amningsduration och mammans skattning av barnets hälsa de tre första levnadsåren. Metod: Studien är en kvantitativ retrospektiv tvärsnittstudie. Data insamlades via enkäter, 418 deltagare inkluderades. Data har analyserats med Statistical Package for the Social Sciences (SPSS). För deskriptiv och jämförande analys har parametriska och icke-parametriska analyser genomförts. Resultat: De kvinnor som inte ammade skattade sitt barns hälsa sämre vid tre års ålder i jämförelse med kvinnor som ammat någon period. Vid tre års ålder skattade kvinnor med övervikt och fetma sitt barns hälsa sämre. Slutsats: Det är viktigt att kunna identifiera kvinnor som är behov av stöd för att initiera amning och kunna bidra till anpassat stöd till dem. AbstractSweden reports high duration of breastfeeding compared to international findings. During the last century, the frequency of breastfeeding duration has decreased in Sweden, with large regional differences. Recommendation for exclusive breastfeeding is six months. Midwives provide information about healthy benefits of breast milk, such as breast milk protecting baby´s against allergies. Research has presented associations between obesity and short duration of breastfeeding. However, there is a lack of knowledge regarding women in a Swedish context. Aim: To investigate the relation between mothers BMI, duration of breastfeeding and maternal valuation of the baby´s health during the first three year of life. Method: The study is a quantitative retrospective cross-sectional study. Data was collected through questionnaires, 418 participants were included. Data was analyzed using the SPSS. For descriptive and comparative analysis parametric and nonparamateric statistics have been used.Results: Women who did not breastfed perceived their baby´s health worse at three years compared with women who did breastfeed. Women with overweight and obesity also perceived the health of their three year old worse than the other maternal group. Conclusions: It´s important to identify women who need support to initiate breastfeeding and give them customized support.
