- Objective: We performed the present study to investigate the feto-maternal osmotic relationship at term with the hypothesis that, in contrast to the literature, maternal plasma osmolality is lower than fetal levels. In a previous study, we found that maternal plasma sodium at delivery was consistently lower than the sodium in the umbilical artery. Our aim was to corroborate these results with analysis of osmolality. Methods: Blood was sampled from 30 women immediately before cesarean section and from the umbilical artery and vein before cord clamping and osmolality, sodium and albumin were analyzed. Results: Maternal osmolality was (mean; 95% confidence interval) 287.0 (285.8-288.2) mOsmkg/kg, arterial cord osmolality was 289.4 (287.9-291.0) mOsm/kg and venous cord osmolality was 287.3 (286.0-288.5) mOsm/kg. The paired difference between maternal and umbilical arterial osmolality was mean (SD) -2.4 (3.3) mOsm/kg (P amp;lt; 0.001), between maternal and umbilical vein -0.3 (3.0) mOsm/kg (P = 0.63) and between umbilical artery and vein -2.1 (2.8) mOsm/kg (P amp;lt; 0.001). Conclusion: Maternal osmolality was significantly lower than arterial cord osmolality confirming our previous results. The feto-maternal osmotic gradient favors water transport from the mother to the fetus and may increase the fetal risk of water intoxication when the mother ingests or is administered large volumes of electrolyte free solutions.

- Background In a previous study we found a significant correlation between dystocia and hyponatraemia that developed during labour. The present study examined a possible causal relationship. In vitro studies often use area under the curve (AUC) determined by frequency and force of contractions as a measure of myometrial contractility. However, a phase portrait plot of isometric contraction, obtained by plotting the first derivate of contraction against force of contraction, could indicate that bi-or multiphasic contractions might be less effective compared to the smooth contractions. Material and methods Myometrial biopsies were obtained from 17 women undergoing elective caesarean section at term. Each biopsy was divided into 8 strips and mounted isometrically in a force transducer. Seven biopsies were used in the first part of the study when half of the strips were immersed in the hyponatraemic study solution S containing Na+ 120 mmol/L and observed for 1 hour, followed by 1 hour in normonatraemic control solution C containing Na+ 136 mmol/L, then again in S for 1 hour, and finally 1 hour in C. The other half of the strips were studied in reverse order, C-S-C-S. The remaining ten biopsies were included in the second part of the study. Response to increasing doses of oxytocin (OT) in solutions S and C was studied. In the first part of the study we calculated AUC, and created phase portrait plots of two different contractions from the same strip, one smooth and one biphasic. In both parts of the study we registered frequency and force of contractions, and described appearance of the contractions. Results First part of the study: Mean (median) contractions per hour in C: 8.7 (7.6), in S 14,3 (13). Mean (SD) difference between groups 5.6 (4.2), p = 0.018. Force of contractions in C: 11.8 (10.2) mN, in S: 10.8 (9.2) mN, p = 0.09, AUC increased in S; p = 0.018. Bi-/multiphasic contractions increased from 8% in C to 18% in S, p = 0.001. All changes were reversible in C. Second part of the study: Frequency after OT 1.65 x 10-(9) M in C:3.4 (2.9), in S: 3.8 (3.2), difference between groups: p = 0.48. After OT 1.65 x 10-(7) M in C: 7.8 (8.9), increase from previous OT administration: p = 0.09, in S: 8.7 (9.0), p = 0.04, difference between groups, p = 0.32. Only at the highest dose of OT dose was there an increase in force of contraction in S, p = 0.05, difference between groups, p = 0.33. Initial response to OT was more frequently bi/multiphasic in S, reaching significance at the highest dose of OT(1.65 x 10-(7) M), p = 0.015. when almost all contractions were bi/multiphasic. Conclusion Hyponatraemia reversibly increased frequency of contractions and appearance of bi-or multiphasic contractions, that could reduce myometrial contractility. This could explain the correlation of hyponatraemia and instrumental delivery previously observed. Contractions in the hyponatraemic solution more frequently showed initial multiphasic contractions when OT was added in increasing doses. Longer lasting labours carry the risk both of hyponatraemia and OT administration, and their negative interaction could be significant. Further studies should address this possibility.

Tidskriftsartikel (refereegranskat)abstract
- Aim and objectives: Describe patients' and family members' perceptions of family support from nurses and other mental healthcare professionals, and quality of care in community mental healthcare service. Further, compare the perceptions of patients and family members.Background: While patients value family involvement, family members feel unprepared and lack the necessary skills to be supportive. Since healthcare professionals predominantly focus on patients, they may fail to understand the complex needs of families. Family perceived support and quality of community mental health care may vary across patients and family members.Design and methods: Cross-sectional study with patients suffering from mental illness and family members in community mental healthcare services in Norway. Altogether 86 participants, of whom 33 patients and 33 family members had a family relationship-paired samples. Participants filled in the translated version of the Iceland Family Perceived Support Questionnaire (FPSQ-N) and Quality in Psychiatric Care-Community Out-Patient (QPC-COP) and Community Out-Patient Next of Kin (QPC-COPNK). STROBE checklist was used.Results: Family members scored family perceived support and quality of community mental health care lower than patients. Family members feel the loss of support. Patient and family members found the Patient-healthcare professionals' relationship to be of high quality, while family members gave low score to being respected and invited to take part in care by nurses and other mental healthcare professionals.Conclusion: Family members' unmet need of support highlights the need for nurses and other community mental healthcare professionals to assess complex family needs and to intervene. Barriers to collaboration exist, and family members need to be respected and invited into community mental health care. Relevance to clinical practice Contributes knowledge of how to meet the family's needs and provides a basis for further care and treatment development in similar contexts nationally and internationally.

- Using electronic health records data and machine learning to guide future decisions needs to address challenges, including 1) long/short-term dependencies and 2) interactions between diseases and interventions. Bidirectional transformers have effectively addressed the first challenge. Here we tackled the latter challenge by masking one source (e.g., ICD10 codes) and training the transformer to predict it using other sources (e.g., ATC codes).

- Many traditional pastoralist systems are greatly impacted by cumulative encroachments of other land users and by climate change. Understanding land degradation and the adaptive capacity of people who are dependent on the rangelands is an urgent priority for many areas in the world. In this research we explore how changing environmental conditions affect herding strategies on winter pastures and the role of indigenous and local traditional knowledge (ILK) in Sami reindeer husbandry. Our results indicate that traditional Sami reindeer herding strategies are still practiced, but that rapidly changing environmental circumstances are forcing herders into uncharted territories where these traditional strategies and the transmission of knowledge between generations may be of limited use. For example, rotational grazing is no longer possible as all pastures are being used, and changes in climate result in unpredictable weather patterns unknown to earlier generations.

Journal article (peer-reviewed)abstract
- During the twenty-first century, large carnivores have increased in human dominated landscapes after being extinct or nearly extinct. This has resulted in increasing numbers of livestock killed by large carnivores. The intent of this paper is to give a land use-historical perspective on the recent livestock-carnivore conflict in boreal Sweden. More specifically we address: (1) depredation risks (livestock killed by carnivores) and (2) local knowledge of how to protect livestock from predation and whether it survived among pastoralists until the present. This study provides numeric information on carnivores, livestock and depredation, combined with oral information from summer farmers about livestock protection. We compare recent (since 1998) and historical (late nineteenth century) depredation rates in two Swedish counties. In Dalarna recent depredation rates are higher than historical rates while the opposite pattern is seen in Jamtland. Recent depredation rates in Dalarna are twice the recent rates in Jamtland, in contrast to the historical situation. Recent and historical depredation rates are of the same order. Summer farmers traditionally graze their livestock in forested areas where carnivores reside. Interviews show that traditional knowledge of how to protect livestock from carnivores was lost during the twentieth century, but recently new knowledge has developed leading to changes in summer farming practices. The carnivore-livestock situation today differs from the historical situation, not so much in levels of depredation, but mainly regarding the possibilities of farmers to face challenges associated with increasing carnivore populations.
