- GRB 221009A is the brightest Gamma Ray Burst (GRB) ever observed. The observed extremelyhigh flux of high and very-high-energy photons provide a unique opportunity to probe the predictedneutrino counterpart to the electromagnetic emission. We have used a variety of methods to searchfor neutrinos in coincidence with the GRB over several time windows during the precursor, promptand afterglow phases of the GRB. MeV scale neutrinos are studied using photo-multiplier ratescalers which are normally used to search for galactic core-collapse supernovae neutrinos. GeVneutrinos are searched starting with DeepCore triggers. These events don’t have directionallocalization, but instead can indicate an excess in the rate of events. 10 GeV - 1 TeV and >TeVneutrinos are searched using traditional neutrino point source methods which take into accountthe direction and time of events with DeepCore and the entire IceCube detector respectively. The>TeV results include both a fast-response analysis conducted by IceCube in real-time with timewindows of T0 − 1 to T0 + 2 hours and T0 ± 1 day around the time of GRB 221009A, as well asan offline analysis with 3 new time windows up to a time window of T0 − 1 to T0 + 14 days, thelongest time period we consider. The combination of observations by IceCube covers 9 ordersof magnitude in neutrino energy, from MeV to PeV, placing upper limits across the range forpredicted neutrino emission.

- Background: Physical inactivity is globally recognized as a major risk factor for morbidity, particularly the incidence of non-communicable diseases, and mortality. Engaging in active transportation (AT) is a viable approach toward increasing physical activity (PA) on a daily basis. Mobile (mHealth) interventions enable promoting AT to a larger population. The Smart City Active Mobile Phone Intervention (SCAMPI) study is a randomized controlled trial designed to evaluate a smartphone application (app)’s ability to motivate participants to increase their PA by engaging in AT.Objective: This qualitative study examines the acceptance and usability of the SCAMPI app from the participants’ perspectives.Methods: Seventeen residents of Stockholm county (13 women; age range 25-61 years), who had completed the three-month, app-based behavioral change program in the SCAMPI randomized controlled trial during 2018 agreed to participate in a semi-structured telephone-based interview. These 17 participants were well representative of the whole intervention group (n = 127) in terms of baseline characteristics such as age, sex, and area of residence. The interviews were audio-recorded, transcribed verbatim, and analyzed using inductive qualitative content analysis.Results: The content analysis revealed two themes and four subcategories. The first theme “Main motivators: monitoring and messages” highlighted that monitoring AT and being able to set weekly goals using the app were the primary motivators reported among study participants. The second theme “Acceptable but modifiable” reflects that the app was well accepted and effectively encouraged many participants to use more AT. Nevertheless, there were functions in the app that require modification. For example, while the automated travel tracking feature was appreciated, participants found it time-consuming and unreliable at times.Conclusions: This study contributes novel insight into healthy adults’ experiences of using a mobile app to promote the use of AT. The results showed that the app was well-accepted and that self-monitoring and goal setting were the main motivators to engage in more AT. The automated tracking of AT was appreciated; however, it was also reported to be energy- and time-consuming when it failed to work. Thus, this feature should be improved going forward.

Perceptions of family planning among low-income men in Western Kenya : Original Article
- 2009

- Background: Men have rarely been involved in either receiving or providing information on sexuality, reproductive health or birth spacing. They have also been ignored or excluded in one way or the other from participating in many family planning programmes as family planning is viewed as a womans affair. Aim: To describe the perceptions of family planning among low-income men in Western Kenya. Methods: A qualitative study using focus group interviews and content analysis was conducted, with 64 men aged 15-54 years participating actively. Findings: Perceptions of family planning were manifold. For example, some perceived it as meaning having the number of children one is able to provide for. Most men knew about traditional and modern methods of birth control, although their knowledge was poor and misconceived. Modern methods were thought to give side effects, discouraging family planning. Low instances of family planning were also because of the fact that culturally, children are considered wealth. A law advocating family size limitation was regarded as necessary for the future. Conclusion: Mens perceptions of family planning are manifold. Their knowledge about contraception is poor and sometimes misconceived. Preferences regarding a childs gender are strong, thus attitudes and cultural beliefs that might hinder family planning have to be considered. A policy on male contraception and contraceptive services is seen as necessary.

- Background & Aims: The aim of this study of women with hip fracture was to describe nutritional status with biochemical markers and anthropometric variables, and to evaluate the effect of nutritional intervention with the intention of increasing protein and energy intake.Methods: The first consecutive 44 women were included, and used as controls. The next 44 were matched for age, fracture and mental state. Anthropometric variables, IGF-I, hormones and serum albumin were collected 4–6 days (baseline), 1 and 3 months after surgery. Twenty-four women filled out a 7-day food record.Results: At baseline, one fourth had BMI <20 kg/m2and subnormal triceps skinfold thickness. Baseline serum albumin, IGF-I and growth hormone levels were low, probably as an acute response to trauma. Women with BMI <20 kg/m2had lower IGF-I levels compared to those with higher BMI. At 3 months, one-third of both groups were protein and energy malnourished. The intervention group obtained higher daily energy percentage from fat but none of the groups reached their calculated energy need.Conclusions: Using biochemical markers in the acute postoperative situation to assess nutritional status is not recommended. The intervention had no impact on anthropometric or biochemical variables.

- The objective of this study was to describe characteristics in a group of elderly men and women with hip fracture, regarding presumed risk factors, such as nutritional state and functional capacity. A total of 142 men and women aged 75 years or more were consecutively included on admittance to the hospital. Anthropometry and body composition were measured 4-6 days after the fracture. Data on functional status, activities of daily living and living arrangements at the time of the fracture were collected. The women and men had a body mass index (BMI) of 22.3 ▒ 3.7 kg/m2 and 21.7 ▒ 2.1 kg/m2, respectively. Of the whole group, 71% had a BMI < 24 kg/m2 and 25% a BMI < 20.0 kg/m2. Forty-five percent of the patients needed daily home help, and a majority of them were mentally impaired (p < 0.0001). Women with a trochanteric hip fracture were shorter, had lower body weight, lower lean body mass and lower arm muscle circumference (AMC) than the cervical fracture group (p < 0.05). Fewer women with a trochanteric fracture and fewer women with mental impairment took walks outside before the fracture, (p = 0.023 and p = 0.002, respectively). Characteristics found in the group were low BMI, low muscle mass as indicated by low lean body mass and mental impairment. It seems important to evaluate such factors when developing post-operative care plans aimed at avoiding further deterioration. Extra frail sub-groups of patients, such as people who are mentally impaired, women with trochanteric fracture and women with high dependency concerning ADL functions were identified.
