- The goal of a medico-legal autopsy is primarily to determine the cause and manner of death. To this end, the pathologist often uses auxiliary analyses, including histology. However, the utility of routine histology in all medico-legal autopsies is unknown. Earlier studies on the utility of routine histology have shown inconsistent effects, with some studies recommending it and others rejecting it. To study the degree to which histology informs on the underlying cause of death, we sent autopsy reports from suspension-, immersion-, fire-, and traffic-related deaths to senior board-certified forensic pathologists and had them assess the cause of death, first without knowledge of the histological findings and then with knowledge thereof. Fifty cases were identified in each of four subgroups: fire-, immersion-, suspension-, and traffic-related deaths. The autopsy reports were anonymized, and the histological findings and conclusions were removed. Two board-certified forensic pathologists independently reviewed the reports in each subgroup and assessed the manner and underlying cause of death (including their certainty of this assessment on a five-level scale) with and without access to histological findings. The probability of changing the underlying cause of death posthistology was low in all study groups. There was a slight increase in the degree of certainty posthistology in cases where the underlying cause of death was not changed, but only when the antehistology certainty was low. Our results suggest that histology does not meaningfully inform on the underlying cause of death in suspension-, immersion-, fire-, and traffic-related deaths except when antehistology certainty is low.

- BACKGROUND: Symptomatic postbariatric hypoglycemia (PBH) is a known complication that can occur a few years after Roux-en-Y gastric bypass (RYGB). There is currently no established rating scale for PBH-associated symptoms developed for use in Swedish populations. The aim of the study was to translate an already existing questionnaire into Swedish and to test its reliability.METHODS: The study included forward and backward translations of the original Dumping Severity Scale (DSS) questionnaire with 8 items regarding symptoms of early dumping and 6 items regarding hypoglycemia, with each item graded on a 4-point Likert scale. The reliability of the Swedish translated questionnaire (DSS-Swe) was estimated using internal consistency and test-retest methods.RESULTS: A total of 200 patients were included in the study. Good internal consistency was demonstrated regarding the items related to early dumping symptoms, with a Cronbach's alpha coefficient of 0.82, and very good agreement in terms of test-retest reliability, with an overall intraclass correlation coefficient (ICC) of 0.91 (95% CI 0.88-0.93). The items related to hypoglycemia yielded a good Cronbach's alpha coefficient of 0.76 and an ICC of 0.89 (95% CI 0.85-0.91).CONCLUSION: The DSS-Swe questionnaire shows good reliability regarding both internal consistency and test-retest performance for use in Swedish populations.

- Fungal communities in Norway spruce (Picea abies) logs in two forests in Sweden were investigated by 454-sequence analyses and by examining the ecological roles of the detected taxa. We also investigated the relationship between fruit bodies and mycelia in wood and whether community assembly was affected by how the dead wood was formed. Fungal communities were highly variable in terms of phylogenetic composition and ecological roles: 1910 fungal operational taxonomic units (OTUs) were detected; 21% were identified to species level. In total, 58% of the OTUs were ascomycetes and 31% basidiomycetes. Of the 231 337 reads, 38% were ascomycetes and 60% basidiomycetes. Ecological roles were assigned to 35% of the OTUs, accounting for 62% of the reads. Wood-decaying fungi were the most common group; however, other saprotrophic, mycorrhizal, lichenized, parasitic and endophytic fungi were also common. Fungal communities in logs formed by stem breakage were different to those in logs originating from butt breakage or uprooting. DNA of specific species was detected in logs many years after the last recorded fungal fruiting. Combining taxonomic identification with knowledge of ecological roles may provide valuable insights into properties of fungal communities; however, precise ecological information about many fungal species is still lacking.

- Background: Small bowel obstruction due to internal hernia is a common and potentially serious complication after laparoscopic gastric bypass surgery. Whether closure of surgically created mesenteric defects might reduce the incidence is unknown, so we did a large randomised trial to investigate.Method: This study was a multicentre, randomised trial with a two-arm, parallel design done at 12 centres for bariatric surgery in Sweden. Patients planned for laparoscopic gastric bypass surgery at any of the participating centres were off ered inclusion. During the operation, a concealed envelope was opened and the patient was randomly assigned to either closure of mesenteric defects beneath the jejunojejunostomy and at Petersen's space or non-closure. After surgery, assignment was open label. The main outcomes were reoperation for small bowel obstruction and severe postoperative complications. Outcome data and safety were analysed in the intention-to-treat population. This trial is registered with ClinicalTrials. gov, number NCT01137201.Findings: Between May 1, 2010, and Nov 14, 2011, 2507 patients were recruited to the study and randomly assigned to closure of the mesenteric defects (n= 1259) or non-closure (n= 1248). 2503 (99.8%) patients had follow-up for severe postoperative complications at day 30 and 2482 (99.0%) patients had follow-up for reoperation due to small bowel obstruction at 25 months. At 3 years after surgery, the cumulative incidence of reoperation because of small bowel obstruction was signifi cantly reduced in the closure group (cumulative probability 0.055 for closure vs 0.102 for non-closure, hazard ratio 0.56, 95% CI 0.41-0.76, p= 0.0002). Closure of mesenteric defects increased the risk for severe postoperative complications (54 [4.3%] for closure vs 35 [2.8%] for non-closure, odds ratio 1.55, 95% CI 1.01-2.39, p= 0.044), mainly because of kinking of the jejunojejunostomy.Interpretation: The results of our study support the routine closure of the mesenteric defects in laparoscopic gastric bypass surgery. However, closure of the mesenteric defects might be associated with increased risk of early small bowel obstruction caused by kinking of the jejunojejunostomy.

- IMPORTANCE: Short-term and midterm data suggest that mesenteric defects closure during laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery reduces the risk of internal herniation with small bowel obstruction (SBO) but may increase risk of kinking of the jejunojejunostomy in the early postoperative period. However, to our knowledge, there are no clinical trials reporting long-term results from this intervention in terms of risk for SBO or opioid use.OBJECTIVE: To evaluate long-term safety and efficacy outcomes of closure of mesenteric defects during LRYGB.DESIGN, SETTING, AND PARTICIPANTS: This randomized clinical trial with a 2-arm, parallel, open-label design included patients with severe obesity scheduled for LRYGB bariatric surgery at 12 centers in Sweden from May 1, 2010, through November 14, 2011, with 10 years of follow-up after the intervention. INTERVENTIONS: During the operation, patients were randomly assigned 1:1 to closure of mesenteric defects beneath the jejunojejunostomy and at the Petersen space using nonabsorbable running sutures during LRYGB or to nonclosure.MAIN OUTCOME AND MEASURES: The primary outcome was reoperation for SBO. New incident, chronic opioid use was a secondary end point as a measure of harm.RESULTS: A total of 2507 patients (mean [SD] age, 41.7 [10.7] years; 1863 female [74.3%]) were randomly assigned to closure of mesenteric defects (n = 1259) or nonclosure (n = 1248). After censoring for death and emigration, 1193 patients in the closure group (94.8%) and 1198 in the nonclosure group (96.0%) were followed up until the study closed. Over a median follow-up of 10 years (IQR, 10.0-10.0 years), a reoperation for SBO from day 31 to 10 years after surgery was performed in 185 patients with nonclosure (10-year cumulative incidence, 14.9%; 95% CI, 13.0%-16.9%) and in 98 patients with closure (10-year cumulative incidence, 7.8%; 95% CI, 6.4%-9.4%) (subhazard ratio [SHR], 0.42; 95% CI, 0.32-0.55). New incident chronic opioid use was seen among 175 of 863 opioid-naive patients with nonclosure (10-year cumulative incidence, 20.4%; 95% CI, 17.7%-23.0%) and 166 of 895 opioid-naive patients with closure (10-year cumulative incidence, 18.7%; 95% CI, 16.2%-21.3%) (SHR, 0.90; 95% CI, 0.73-1.11).CONCLUSIONS AND RELEVANCE: This randomized clinical trial found long-term reduced risk of SBO after mesenteric defects closure in LRYGB. The findings suggest that routine use of this procedure during LRYGB should be considered.TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT01137201.

- Objective: to describe the qualitatively different ways in which midwives make sense of how to approach women smokers. Design, setting and participants: a more person-centred national project 'Smoke-free pregnancy' has been in progress in Sweden since 1992. Using a phenomenographic approach, 24 midwives who have been regularly working in antenatal care were interviewed about addressing smoking during pregnancy. Findings: four different story types of how the midwives made sense of their experiences in addressing smoking in pregnancy were identified: 'avoiding', 'informing', 'friend-making', 'co-operating'. Key conclusion: the midwives' story types about how they approached women who smoke illustrated the difficulties of changing from being an expert who gives information and advice to being an expert on how to enable a woman in finding out why she smoked and how to stop smoking. Implications for practice: health education about smoking that is built on cooperation and dialogue was seen by the midwives as a productive way of working. The starting point should be the lay perspective of a woman, which means that her thoughts about smoking cessation are given the space to grow while she talks.

- Robustness analysis of HOG pathway genes in Saccharomyces cerevisiae Doryaneh Ahmadpour1, Lars-Göran Ottosson1, Markus Krantz2, Jonas Warringer1, Anders Blomberg1 and Stefan Hohmann1* 1Department of Cell and Molecular Biology/Microbiology, Göteborg University, S-405 30 Göteborg, Sweden 2 The Systems Biology Institute (SBI), Shibuya, Tokyo, Japan E-mail: doryaneh.ahmadpour@gmm.gu.se Robustness is a fundamental property of biological systems and crucial for their effective function under internal or external perturbations. For instance, it has been proposed that internal parameters such as gene expression have been optimized during evolution such that a given system has the observed robustness. The permissible ranges of internal parameters in the cells are not comprehensively understood since there has not been a technique to measure such parameters. “Genetic tug-of-war” (gTOW) [1] is a genetic screening method that allows the investigation of the upper limit copy number of genes, and thereby the upper permissible range of gene expression level. This method is based on a 2-micron plasmid vector containing the leu2d allele with a very weak complementation activity and the gene of interest inserted as target gene. When the leu2ura3 deletion yeast cells transformed with pTOW plasmid are cultured under leucine-limiting conditions, there will be a bias toward increasing the plasmid copy number to compensate for the lack of leucine. On the other hand there will be an opposing bias toward decreasing the plasmid copy number if the target gene inhibits growth or has a toxic effect when a certain copy number is exceeded (it reaches to its upper limit). Eventually as a result of the “tug-of-war” between these two selection biases cells with optimized plasmid copy number will be concentrated. In this study we have applied the gTOW method on 29 HOG pathway related genes in Saccharomyces cerevisiae. The high osmolarity glycerol (HOG) MAPK pathway is essential for yeast survival in high osmolarity condition and consists of two branches that activate a MAPK (Hog1) via a MAPKK (Pbs2) to orchestrate part of the transcriptional response. The HOG pathway is the best understood osmoresponsive system in eukaryotes and the quantitative data provided by the gTOW method collating with the existing computational models could be used to analyze the robustness and fragility of the pathway. 1.
