Tidskriftsartikel (refereegranskat)abstract
- A Papanicolaou (Pap) smear can be used to detect pre-cancerous cellular changes, so that they can be treated before they develop into cervical cancer. When the results of a Pap smear test are abnormal, women need further investigation, treatment and follow-up. Healthcare professionals (HCPs) are in a position to care for these women with abnormalities. The aim of this study was to explore the experiences of HCPs in caring for women with abnormal Pap smear results. In total, 20 HCPs from two counties in south-eastern Sweden participated in individual interviews, based on two open-ended questions. Interviews were recorded, transcribed verbatim and analysed using content analysis. The results showed that HCPs experienced that abnormal Pap smear results created anxiety in women, who often sought information from the Internet as a way to cope. Furthermore, the HCPs thought that it was a problem that women chose not to attend investigation, treatment and follow-ups. However, information about the seriousness of abnormal Pap smear results causes women to participate. It is a challenge for HCPs to inform in a reassuring manner. Finally, HCPs should collaborate with women to meet their information needs and to also provide support regarding finding and filtering reliable information on the Internet.

Journey to the destination: a circular tourism economy : a training program for the hospitality industry to facilitate a transition towards increased circularity in the South Baltic Region
- 2019
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Being aware of the extent of the tourism industry and that it is ever growing, which is also encouraged in many individual countries by the national and regional governments, it is evident that the tourism industry is an essential target group for introducing circular concepts and implementing circular solutions. Yet, this sector has so far received little attention in the literature and initiatives on circularity.Circular Economy (CE) goes beyond “green” or “environmental”, it includes all aspects of a community and challenges us to create solutions that are completely different from what we are used to. It also invites us to open up and interact with other stakeholders and the general public.In your hands is the first training material in circular economy specifically developed for small to medium sized companies of the tourism industry in the South Baltic Region. It is a small but important step in the direction towards circularity and a wellbeing society. Through this work we have shown that despite cultural challenges and regional differences there is a shared, common interest in making tourism more sustainable and even to work together towards a transformation of the hospitality industry. This common vision has been stronger than the challenges we faced in making this work and this is what will ensure the continued growing awareness on circularity and its integration in different sectors in our communities. In this work we have featured some of the groundbreaking experts in this field, and some of the first good practices from our regions. They are all courageous pioneers in a field that with time will become the norm. In fact, in the 10th Annual Forum of the EU strategy for the Baltic Sea Region (12-13/6/2019, Gdansk, Poland), CE was highlighted as the pathway to reach prosperity and wellbeing in the Baltic Sea Region.

Tidskriftsartikel (refereegranskat)abstract
- Background/Aims: Preliminary clinical trials have suggested that dearterialization (interruption of arterial blood supply) is beneficial to patients with liver tumours. The aim of this report was to review the outcome of all patients undergoing dearterialization for colorectal liver metastases and to analyze whether refinement of the technique was followed by improvement in outcome. Methods: Retrospective review of 57 patients undergoing temporary (16 h) dearterialization during 1972-1984 (n = 24) or repeated transient dearterialization (1-2 h once or twice daily) during 1985-1995 (n = 33). Results: The median survival after start of treatment was 1.1 years, and the 5-year survival rate was 0%. There was no significant difference in survival between temporary and repeated transient dearterialization. Liver tumour volume and extrahepatic metastases varied negatively with survival. The temporary dearterialization procedure was followed by hepatic or intra-abdominal abscess formation in 6 patients (24%), leading to postoperative death in 2 patients (operative mortality 8%). Complications after repeated transient dearterialization were related mainly to technical problems with the occluder device. Conclusion: Although this was not a randomized study, it appears that dearterialization is of no benefit in colorectal liver cancer.

Early rearing history influences oxytocin receptor epigenetic regulation in rhesus macaques

- Adaptations to stress can occur through epigenetic processes and may be a conduit for informing offspring of environmental challenge. We employed ChIP-sequencing for H3K4me3 to examine effects of early maternal deprivation (peer-rearing, PR) in archived rhesus macaque hippocampal samples (male, n = 13). Focusing on genes with roles in stress response and behavior, we assessed the effects of rearing on H3K4me3 binding by ANOVA. We found decreased H3K4me3 binding at genes critical to behavioral stress response, the most robust being the oxytocin receptor gene OXTR, for which we observed a corresponding decrease in RNA expression. Based on this finding, we performed behavioral analyses to deter mine whether a gain-of-function nonsynonymous OXTR SNP inter acted with early stress to influence relevant behavioral stress reactivity phenotypes (n = 194), revealing that this SNP partially rescued the PR phenotype. PR infants exhibited higher levels of separation anxiety and arousal in response to social separation, but infants carrying the alternative OXTR allele did not exhibit as great a separation response. These data indicate that the oxytocin system is involved in social-separation response and suggest that epigenetic down-modulation of OXTR could contribute to behavior al differences observed in PR animals. Epigenetic changes at OXTR may represent predictive adaptive responses that could impart readiness to respond to environmental challenge or maintain proximity to a caregiver but also contribute to behavioral pathology. Our data also demonstrate that OXTR polymorphism can permit animals to partially overcome the detrimental effects of early maternal deprivation, which could have translational implications for human psychiatric disorders.

Viruses affect picocyanobacterial abundance and biogeography in the North Pacific Ocean

Tidskriftsartikel (refereegranskat)abstract
- The photosynthetic picocyanobacteria Prochlorococcus and Synechococcus are models for dissecting how ecological niches are defined by environmental conditions, but how interactions with bacteriophages affect picocyanobacterial biogeography in open ocean biomes has rarely been assessed. We applied single-virus and single-cell infection approaches to quantify cyanophage abundance and infected picocyanobacteria in 87 surface water samples from five transects that traversed approximately 2,200 km in the North Pacific Ocean on three cruises, with a duration of 2–4 weeks, between 2015 and 2017. We detected a 550-km-wide hotspot of cyanophages and virus-infected picocyanobacteria in the transition zone between the North Pacific Subtropical and Subpolar gyres that was present in each transect. Notably, the hotspot occurred at a consistent temperature and displayed distinct cyanophage-lineage composition on all transects. On two of these transects, the levels of infection in the hotspot were estimated to be sufficient to substantially limit the geographical range of Prochlorococcus. Coincident with the detection of high levels of virally infected picocyanobacteria, we measured an increase of 10–100-fold in the Synechococcus populations in samples that are usually dominated by Prochlorococcus. We developed a multiple regression model of cyanophages, temperature and chlorophyll concentrations that inferred that the hotspot extended across the North Pacific Ocean, creating a biological boundary between gyres, with the potential to release organic matter comparable to that of the sevenfold-larger North Pacific Subtropical Gyre. Our results highlight the probable impact of viruses on large-scale phytoplankton biogeography and biogeochemistry in distinct regions of the oceans.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To evaluate the oncological outcome for patients with colorectal liver metastases (CRLM) randomized to associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) or 2-stage hepatectomy (TSH). Background: TSH with portal vein occlusion is an established method for patients with CRLM and a low volume of the future liver remnant (FLR). ALPPS is a less established method. The oncological outcome of these methods has not been previously compared in a randomized controlled trial. Methods: One hundred patients with CRLM and standardized FLR (sFLR) <30% were included and randomized to resection by ALPPS or TSH, with the option of rescue ALPPS in the TSH group, if the criteria for volume increase was not met. The first radiological follow-up was performed approximately 4 weeks postoperatively and then after 4, 8, 12, 18, and 24 months. At all the follow-ups, the remaining/recurrent tumor was noted. After the first follow-up, chemotherapy was administered, if indicated. Results: The resection rate, according to the intention-to-treat principle, was 92% (44 patients) for patients randomized to ALPPS compared with 80% (39 patients) for patients randomized to TSH (P = 0.091), including rescue ALPPS. At the first postoperative follow-up, 37 patients randomized to ALPPS were assessed as tumor free in the liver, and also 28 patients randomized to TSH (P = 0.028). The estimated median survival for patients randomized to ALPPS was 46 months compared with 26 months for patients randomized to TSH (P = 0.028). Conclusions: ALPPS seems to improve survival in patients with CRLM and sFLR <30% compared with TSH.

Future Liver Remnant (FLR) Increase in Patients with Colorectal Liver Metastases Is Highest the First Week After Portal Vein Occlusion: FLR Increase in Patients with CRLM Is Highest the First Week After PVO

Tidskriftsartikel (refereegranskat)abstract
- BackgroundPortal vein occlusion (PVO) is an established method to increase the volume of the future liver remnant (FLR). The main reasons for not proceeding to radical hepatectomy are lack of volume increase and tumor progression due to a wait-time interval of up to 8weeks. The hypothesis was that the increase in FLR volume is not linear and is largest during the first weeks.MethodsPatients with colorectal liver metastases (CRLM) and standardized future liver remnant (sFLR) <30% treated with PVO were prospectively included. All patients had at least one CT evaluation before radical hepatectomy.ResultsForty-eight patients were included. During the first week after PVO, the kinetic growth rate (KGR) was 5.4 (4), compared to 1.5 (+/- 2) between the first and second CT (p<0.05). For patients reaching adequate FLR and therefore treated with radical hepatectomy, the KGR was 7 (+/- 4) the first week, compared to 4.3 (+/- 2) for patients who failed to reach a sufficient volume (p=0.4). During the interval between the first and second CT, the KGR was 2.2 (+/- 2), respectively (+/- 0.1) (p=0.017).Discussion p id=Par4 The increase in liver volume after PVO is largest during the first week. As KGR decreases over time, it is important to shorten the interval between PVO and the first volume evaluation; this may aid in decision-making and reduce unnecessary waiting time.

Tidskriftsartikel (refereegranskat)abstract
- Background: Liver metastases are the most common cause of death for patients with colorectal cancer and affect up to half of the patients. Liver resection is an established method that can potentially be curative. For patients with extrahepatic disease (EHD), the role of liver surgery is less established. Methods: This is a retrospective study based on data from the national quality registry SweLiv. Data were obtained between 2009 and 2015. SweLiv is a validated registry and has been in use since 2009, with coverage above 95%. Patients with liver metastases and EHD were analyzed and cross-checked against the national death cause registry for survival analysis. Results: During the study period, 2,174 patients underwent surgery for colorectal liver metastases (CRLM), and 277 patients with EHD were treated with resection or ablation. The estimated median survival time for the entire cohort from liver resection/ablation was 40 months (95% CI, 32-47). The survival time for patients treated with liver resection was 45 months compared to 26 months for patients treated with ablation (95% CI 38-53, 18-33, P=0.001). A subgroup analysis of resected patients revealed that the group with pulmonary metastases had a significantly longer estimated median survival (50 months; 95 % CI, 39-60) than the group with lymph node metastases (32 months; 95% CI, 7-58) or peritoneal carcinomatosis (28 months; 95% CI, 14-41) (P=0.022 and 0.012, respectively). Other negative prognostic factors were major liver resection and nonradical liver resection. Conclusions: For patients with liver metastases and limited EHD, liver resection results in prolonged survival compared to what can be expected from chemotherapy alone.

- Background Consistent data on clinical features, treatment modalities and long-term survival in patients with hepatocellular carcinoma (HCC) using nationwide quality registers are lacking. This study aimed to describe treatment patterns and survival outcomes in patients diagnosed with HCC using a national maintained database. Methods Characteristics and treatment patterns in patients diagnosed with HCC and registered in the national register of liver and bile duct tumours (SweLiv) between 2009 and 2016 were reviewed. Overall survival (OS) was estimated using Kaplan-Meier analysis and the log rank test to compare subgroups for clinical features, treatment modalities and outcomes according to the year of treatment. Results A total of 3376 patients with HCC were registered over 8 years, 246 (7 center dot 3 per cent) of whom underwent transplantation. Some 501 (14 center dot 8 per cent) and 390 patients (11 center dot 6 per cent) had resection and ablation as primary treatment. Transarterial chemoembolization and systemic sorafenib treatment were intended in 476 (14 center dot 1 per cent) and 426 patients (12 center dot 6 per cent) respectively; the remaining 1337 (39 center dot 6 per cent) were registered but referred for best supportive care (BSC). The 5-year survival rate was approximately 75 per cent in the transplantation group. Median OS was 4 center dot 6 (i.q.r. 2 center dot 0 to not reached) years after resection and 3 center dot 1 (2 center dot 3-6 center dot 7) years following ablation. In patients referred for palliative treatment, median survival was 1 center dot 4 (0 center dot 8-2 center dot 9), 0 center dot 5 (0 center dot 3-1 center dot 2) and 0 center dot 3 (0 center dot 1-1 center dot 0) years for the TACE, sorafenib and BSC groups respectively (P amp;lt; 0 center dot 001). Median survival was 0 center dot 9 years for the total HCC cohort in 2009-2012, before publication of the Swedish national treatment programme, increasing to 1 center dot 4 years in 2013-2016 (P amp;lt; 0 center dot 001). Conclusion The survival outcomes reported were in line with previous results from smaller cohorts. The introduction of national guidelines may have contributed to improved survival among patients with HCC in Sweden.

- Background: In recent years an increase of the incidence of nosocomial outbreaks caused by noroviruses has been observed throughout Sweden, with high peaks noted in the winter seasons 2002/2003 and 2004/2005, respectively. Objectives: To phylogenetically characterize norovirus strains causing nosocomial outbreaks from 1997 to 2005 and estimate the impact of norovirus-like disease on the Swedish health care system during the peak season 2002/2003 when a new variant of norovirus occurred. Study design: Stool samples from 115 randomly selected nosocomial outbreaks occurring during 1997-2005 throughout Sweden were studied by RT-PCR and sequencing. In addition, to investigate the impact on the health-care system, a questionnaire was distributed to infection control units (n = 90) serving all Swedish hospitals, nursing homes and other health-care institutions during the largest epidemic of nosocomial outbreaks. Results: Sequencing of 279 nucleotides of the norovirus RNA polymerase gene in stools containing norovirus RNA showed that strains belonging to the GII.4 genotype dominated. Each of the two large epidemics was due to a new variant within this cluster. The questionnaire revealed that 30,000-35,000 episodes of nosocomial norovirus-like infections occurred in 80 of 82 major Swedish hospitals affected in 2002/2003. Conclusion: New norovirus variants within the cluster GGII.4 may have a major impact on the health-care system. (c) 2008 Elsevier B.V. All rights reserved.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- What distinguishes a metal from an insulator? The macroscopic differences are apparent: we immediately note the distinction between the shiny metal which conducts electricity and the colored, sometimes transparent appearance of the insulator. But which are the microscopic criteria that tell us to which of these two macroscopic classes a certain material should belong? An answer to this question must involve an understanding, at least qualitatively of the nature of the electronic system in question.

Interface Engineering in Organic Electronics
- 2011

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Organic electronics is a field covering all applications and devices where one or several of the active components are made of organic material, such as organic light emitting diodes, organic solar cells, organic thin film transistors, organic magnets for spintronics etc. In all of the applications mentioned above, transport of charges across both inorganic/organic and organic/organic interfaces play a key role for device performance. In order to achieve high efficiencies and longer life-times, proper matching of the electronic energy levels of the different materials is needed.The aim of the research presented in this thesis has been to explore different routes to optimize interface energetics and gain deeper knowledge of the mechanisms that govern charge transport over the interface. Photoelectron spectroscopy (PES) is a method well suited to study both interactions between different materials taking place at surfaces as well as interface energetics.One way to achieve proper matching of interfaces energy levels is by adding a dipole layer. In the three first papers presented in the thesis, the method of adding a monolayer of small organic molecules to change the work function of the surface is investigated. We start with a model system consisting of a nickel surface and PPDA molecules where we have strong interaction and mixing of orbitals between the molecule and the metal surface. The second system consists of a gold surface and TDAE molecules with weaker interaction with integer electron transfer and finally in the third paper an organic surface VPP-PEDOT-Tos is modified, with TDAE, to create a transparent low work function organic electrode. In the fourth paper, we focus on gaining deeper understanding of the Integer Charge Transfer (ICT) model and the mechanisms governing the alignment of energy levels at organic/(in)organic interfaces and in the fifth paper we continue to challenge this model by using it to predict the behavior of a bilayer device, in terms of energy level alignment.

Monitoring of persistent organic pollutants (POPs): Examples from Lake Vattern, Sweden
- 2001
-
Ingår i: Ambio: a Journal of Human Environment. - 0044-7447. ; 30:8, s. 545-551
-
Tidskriftsartikel (refereegranskat)abstract
- Lake Vattern in southern Sweden is a large oligotrophic lake with high surface to catchment area ratio (ca. 0.4) and a water residence time of 60 years. The lake combines sensitivity to atmospheric POP-pollution with general susceptibility for effects of POPs and slow concentration decline. Time series, from the 1960s until 1996, of PCBs and DDT in fish and data on TCDD in sediment of L. Vattern are presented and compared to other large lakes. The long time dataset of POPs in Arctic char (Salvelinus salvelinus) shows a significant annual decline of about 5% for PCBs and 13% for DDT. These rates are in agreement with other studies. Nutrients as well as biological effects and factors affecting the fate of POPs in oligotrophic lakes with long residence times are discussed. We propose that oligotrophic clear lakes are important ecosystems for monitoring POPs in biota.

- Escalation of voluntary alcohol drinking is characteristic of alcohol addiction and can be induced in rodents using intermittent access to alcohol. This model has been used to evaluate candidate therapeutics, but key systems involved in the transition into alcohol addiction, such as CRF, differ in their organization between rodents and primates. We examined the ability of an intermittent access schedule to induce escalation of voluntary alcohol drinking in non-human primates and used this model to assess the role of corticotropin releasing hormone (CRF) signaling in this process.

Clinical studies on cystinuria : With special reference to treatment with tiopronin
- 1996
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Cystinuria is an inherited disorder of the renal tubular transport of cystine and the dibasic amino acids across cell membranes. Defective renal tubular reabsorption causes a greatly increased urinary excretion of thepoorly soluble cystine, which in turn results in the formation of renal stones. Because of the life-long tendency for stone formation the patients are highly susceptible to complications of renal stone disease. Urinary supersaturation of cystine can be counteracted by reducing the urinary concentration (increased fluid intake, chemical modification with a sulfhydryl compound) or by increasing its solubility (urinary alkalinization). Long-tenn treatment with the sulfhydryl compound tiopronin (2-mercaptopropionylglycine) was evaluated in 31 patients with homozygous cystinuria (Papers I, II, IV). The patients were followed over an average of 7.8 years and the treatment was monitored by regular measurements of cystine in 24-hour urine samples by ionexch: mge chromatography, and by X-ray examinations. In 40 cystimnic patients total and split kidney function were investigated by gamma camera renography and measurement of glomerular filtration rate (GFR), mainly51CR-EDTA-clearance (Paper Ill). The diurnal variations in urinary cystine excretion was studied in 8 patients (Paper VI), and the effect of a low sodium intake in 13 (Paper V). A urinary free cystine concentration below the assumed level of saturation of 1200 J..Lmol/1 in 24h urine samples was achieved in 90% of patients treated with tiopronin. The required doses varied from 500 to 3000 mg!day which illustrates the necessity for individualization of treatment by regular measurements of the urinary cystine concentration. Increasing doses of tiopronin resulted in an unexpected decrease in the urinary excretion of the soluble tiopronin-cysteine mixed disulphide suggesting an influence on the general metabolism of cystine and cysteine. The rate of new stone· formation wa<> reduced by 60% and the need for active stone removal by 72%. Stone fonnation was eliminated in two thirds of the patients. In the remaining third there was some formation ofrenal stones in spite of acceptable concentrations of cystine in 24h samples. This shows that also the therapeutic level of urinary cystine has to be individually adjusted in some patients. Measurements of cystine in6h samples in patients without tiopronin treatment revealed considerable variations with peak concentration exceeding the corresponding 24h concentration by as mUch as 91%. Fractionated urine sampling may therefore be a tool for further adjustment of therapy. Treatment with tiopronin was well tolerated by the majority of patients, and the finding of clinically reversible membranous glomerulonephritis in 3 patients does not disqualify the drug from further use. Thirty per cent of 40 patients had light to moderate impainnent of renal function. Only 28% had an entirely normal renal function with both GFR and renography within nonnallimits, but there was no case with severe renal impairment. A renographic comparison between the pre-treatment and treatment periods suggested that the stone-preventing treatment based on monitoring of urinary cystine concentration resulted in preservation of renal function. Restriction of sodium intake resulted in a decrease in urinary cystine excretion in patients without tiopronin treatment, whereas the effect was significantly less in patients with tiopronin. In the patients without tiopronin the sodium delivery conveyed by sodium bicarbonate treatment neutralized the increased solubility of cystine obtained by its alkalinizing effect. The excretion of the disulphide between tiopronin and cysteine wasalso sodium dependent suggesting an active tubular reabsorption of this compound.

- Background: Liver resection for colorectal liver metastases offers a 5-year survival rate of 25%-58%. This study aimed to analyze whether patients with colorectal liver metastases undergo resection to an equal extent and whether selection factors play a role in the selection process. Material and Methods: Data were retrieved from the Swedish Colorectal Cancer Registry (2007-2011) for colorectal cancer and colorectal liver metastases. The patients identified were linked to the Swedish Registry of Liver and Bile surgery and the National Patient Registry to identify whether liver surgery or ablative treatment was performed. Analyses for age, sex, type of primary tumor and treating hospital (university, county, or district), American Society of Anesthesiologists class, and radiology for detection of metastatic disease were performed. Results: Of 28,355 patients with colorectal cancer, 21.6% (6127/28,355) presented with liver metastases. Of the patients with liver metastases, 18.5% (1134/6127) underwent liver resection or ablation. The cumulative proportion of liver resection/ablation was 4% (1134/28,355) of all colorectal cancer. If "not bowel resected" were excluded, the proportion slightly increased to 4.7% (1134/24,262). Around 15% of the patients with metastases were registered as referrals for liver surgery. In a multivariable analysis patients treated at a university hospital for primary tumor were more frequently surgically treated for liver metastases (p < 0.0001). Patients with liver metastases from rectal cancer (p < 0.0001) and men more often underwent liver resection (p = 0.006). A difference was found between health-care regions for the frequency of liver surgery (p < 0.0001). Patients >70 years and those with American Society of Anesthesiologists class >2 underwent liver resection less frequently. Magnetic resonance imaging of the liver was more often used in diagnostic work-up in men. Conclusion: Patients with colorectal liver metastases are unequally treated in Sweden, as indicated by the low referral rate. The proximity to a hepatobiliary unit seems important to enhance the patient's chances of being offered liver surgery.

- A Papanicolaou (Pap) smear can be used to detect pre-cancerous cellular changes, so that they can be treated before they develop into cervical cancer. When the results of a Pap smear test are abnormal, women need further investigation, treatment and follow-up. Healthcare professionals (HCPs) are in a position to care for these women with abnormalities. The aim of this study was to explore the experiences of HCPs in caring for women with abnormal Pap smear results. In total, 20 HCPs from two counties in south-eastern Sweden participated in individual interviews, based on two open-ended questions. Interviews were recorded, transcribed verbatim and analysed using content analysis. The results showed that HCPs experienced that abnormal Pap smear results created anxiety in women, who often sought information from the Internet as a way to cope. Furthermore, the HCPs thought that it was a problem that women chose not to attend investigation, treatment and follow-ups. However, information about the seriousness of abnormal Pap smear results causes women to participate. It is a challenge for HCPs to inform in a reassuring manner. Finally, HCPs should collaborate with women to meet their information needs and to also provide support regarding finding and filtering reliable information on the Internet.

- Objective: The aim of the study was to evaluate if associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) could increase resection rates (RRs) compared with two-stage hepatectomy (TSH) in a randomized controlled trial (RCT). Background: Radical liver metastasis resection offers the only chance of a cure for patients with metastatic colorectal cancer. Patients with colorectal liver metastasis (CRLM) and an insufficient future liver remnant (FLR) volume are traditionally treated with chemotherapy with portal vein embolization or ligation followed by hepatectomy (TSH). This treatment sometimes fails due to insufficient liver growth or tumor progression. Methods: A prospective, multicenter RCTwas conducted between June 2014 and August 2016. It included 97 patients with CRLM and a standardized FLR (sFLR) of less than 30%. Primary outcome-RRs were measured as the percentages of patients completing both stages of the treatment. Secondary outcomes were complications, radicality, and 90-day mortality measured from the final intervention. Results: Baseline characteristics, besides body mass index, did not differ between the groups. The RR was 92% [ 95% confidence interval (CI) 84%-100%] (44/48) in the ALPPS arm compared with 57% (95% CI 43%-72%) (28/49) in the TSH arm [rate ratio 8.25 (95% CI 2.6-26.6); P < 0.0001]. No differences in complications (Clavien- Dindo >= 3a) [ 43% (19/44) vs 43% (12/28)] [1.01 (95% CI 0.4-2.6); P = 0.99], 90-day mortality [8.3% (4/48) vs 6.1% (3/49)] [ 1.39 [95% CI 0.3-6.6]; P = 0.68] or R0 RRs [77% (34/44) vs 57% (16/28)] [2.55 [95% CI 0.9-7.1]; P = 0.11)] were observed. Of the patients in the TSH arm that failed to reach an sFLR of 30%, 12 were successfully treated with ALPPS. Conclusion: ALPPS is superior to TSH in terms of RR, with comparable surgical margins, complications, and short- term mortality.

- Background: Genetic factors interact with environmental stressors to moderate risk for human psychopathology, but sex may also be an important mediating factor. Different strategies for coping with environmental stressors have evolved in males and females, and these differences may underlie the differential prevalence of certain types of psychopathology in the two sexes. In this study, we investigated the possibility of sex-specific gene-environment interactions in a nonhuman primate model of response to social threat. Methods: Rhesus macaques (77 males and 106 females) were exposed to an unfamiliar conspecific. Using factor analysis, we identified three behavioral factors characterizing the response to social threat. Monkeys were genotyped for the serotonin transporter-linked polymorphism (5-HTTLPR), and the effects of genotype, early life stress, and sex on behavioral responses were evaluated. Results: Factor analysis produced five factors: High-Risk Aggression, Impulsivity/Novelty-Seeking, Gregariousness/Boldness, Harm Avoidance, and Redirected Aggression. Overall, males displayed higher levels of High-Risk Aggression and Gregariousness/Boldness than females. Levels of High-Risk Aggression in males carrying the s allele were significantly higher if they were also exposed to early adversity in the form of peer rearing. Conclusions: Our findings support those from studies in humans suggesting that males are more vulnerable to externalizing or aggression-related disorders. The results highlight the importance of interactions that exist among behavior, genes, and the environment and suggest that sex differences in vulnerability to psychopathology may be grounded in our evolutionary history.

- Background and objective: Gallbladder cancer (GBC) is a rare malignancy in the Nordic countries and no common Nordic treatment guidelines exist. This study aimed to characterize the current diagnostic and treatment strategies in the Nordic countries and disclose differences in these strategies. Methods: This was a survey study with a cross-sectional questionnaire of all 19 university hospitals providing curative-intent surgery for GBC in Sweden, Norway, Denmark, and Finland. Results: In all Nordic countries except Sweden, neoadjuvant/downstaging chemotherapy was used in GBC patients. In T1b and T2, majority of the centers (15-18/19) performed extended cholecystectomy. In T3, majority of the centers (13/19) performed cholecystectomy with resection of segments 4b and 5. In T4, majority of the centers (12-14/19) chose palliative/oncological care. The centers in Sweden extended lymphadenectomy beyond the hepatoduodenal ligament, whereas all other Nordic centers usually limited lymphadenectomy to the hepatoduodenal ligament. All Nordic centers except those in Norway used adjuvant chemotherapy routinely for GBC. There were no major differences between the Nordic centers in diagnostics and follow-up. Conclusions: The surgical and oncological treatment strategies of GBC vary considerably between the Nordic centers and countries.

- Background Colorectal cancer is one the most common cancers in the western world with increasing incidence. Approximately 50% of the patients develop liver metastases. Resection of liver metastases is the treatment of choice although almost half of the resected patients get recurrence in the liver. Methods The ASAC trial is a Scandinavian, multicentre, double-blinded, randomized, placebo-controlled study to determine whether adjuvant treatment with low-dose aspirin (acetylsalicylic acid (ASA)) can improve disease-free survival in patients treated for colorectal cancer liver metastases (CRCLM). Up to 800 patients operated for CRCLM will be randomized to Arm#1 ASA 160 mg once daily or Arm#2 Placebo, for a period of 3 years or until disease recurrence. The patients will be recruited at all major hepatobiliary surgical units in Norway, Sweden and Denmark and have follow-up according to standard of care and the National Guidelines. Discussion The ASAC trial will be the first clinical interventional trial to assess the potential beneficial role of ASA in recurrence of CRCLM and survival. ASA is an inexpensive, well-tolerated and easily accessible drug that will be highly potential as adjuvant drug in secondary prevention of CRCLM if the study shows a beneficial effect. We will also determine the effect of ASA as adjuvant treatment on Health-Related Quality of Life and the cost-effectiveness.
