- During a pre-site survey and construction of a new metro route and station in Copenhagen, fossiliferous organic-rich sediments were encountered. This paper reports on multidisciplinary investigations of these organic sediments, which occurred beneath a sediment succession with a lower till, glacifluvial sand and gravel, an upper till and glacifluvial sand. The organic sediments were underlain by glacifluvial sand and gravel. The organic-rich sediments, which were up to 0.5 m thick, accumulated in a low-energy environment, possibly an oxbow lake. They were rich in plant fossils, which included warmth-demanding trees and other species, such as Najas minor, indicating slightly higher summer temperatures than at present. Freshwater shells were also frequent. Bithynia opercula allowed the sediments to be put into an aminostratigraphical framework. The amino acid racemization (AAR) ratios indicate that the organic sediments formed during Marine Isotope Stage 7 (MIS 7), which is consistent with optically stimulated luminescence dating that gave ages of 206 and 248 ka from the underlying minerogenic deposit. The assemblages from Trianglen are similar to interglacial deposits from the former Free Port (1.4 km away) in Copenhagen, except that Corbicula and Pisidium clessini were not found at Trianglen. The presence of these bivalves at the Free Port and the ostracod Scottia tumida at Trianglen indicates a pre-Eemian age. AAR data from archived Bithynia opercula from the Free Port were almost identical to those from Trianglen, indicating that the two sites are contemporary. We suggest the Trianglen interglacial be used as a local name for the MIS 7 interglacial deposits in Copenhagen. MIS 7 deposits have rarely been documented from the region, but MIS 7 deposits may have been mistaken for other ages. The use of AAR ratios in Bithynia opercula has a great potential for correlation of interglacial non-marine deposits in mainland northern Europe.

- Background Neuro-oncology patients and caregivers should have equitable access to rehabilitation, supportive-, and palliative care. To investigate existing issues and potential solutions, we surveyed neuro-oncology professionals to explore current barriers and facilitators to screening patients' needs and referral to services.Methods Members of the European Association of Neuro-Oncology and the European Organisation for Research and Treatment of Cancer Brain Tumor Group (EORTC-BTG) were invited to complete a 39-item online questionnaire covering the availability of services, screening, and referral practice. Responses were analyzed descriptively; associations between sociodemographic/clinical variables and screening/referral practice were explored.Results In total, 103 participants completed the survey (67% women and 57% medical doctors). Fifteen professions from 23 countries were represented. Various rehabilitation, supportive-, and palliative care services were available yet rated "inadequate" by 21-37% of participants. Most respondents with a clinical role (n = 94) declare to screen (78%) and to refer (83%) their patients routinely for physical/cognitive/emotional issues. Survey completers (n = 103) indicated the main reasons for not screening/referring were (1) lack of suitable referral options (50%); (2) shortage of healthcare professionals (48%); and (3) long waiting lists (42%). To improve service provision, respondents suggested there is a need for education about neuro-oncology-specific issues (75%), improving the availability of services (65%) and staff (64%), developing international guidelines (64%), and strengthening the existing evidence-base for rehabilitation (60%).Conclusions Detecting and managing neuro-oncology patients' and caregivers' rehabilitation, supportive,- and palliative care needs can be improved. Better international collaboration can help address healthcare disparities.

- Background: As part of I-O Optimise, a multinational research platform providing real-world insights into the management of lung cancers, the SCAN-LEAF study aims to describe the epidemiology, clinical care and outcomes for pts with NSCLC in Scandinavia. We report initial Tx and OS for pts with NSCLC prior to the availability of immunotherapies in Sweden. Methods: The analysis includes all adult pts diagnosed with NSCLC at Uppsala and Karolinska (Stockholm) University Hospitals from 2012 to 2015 (follow-up to Dec 2016). Electronic medical record data were extracted using Pygargus CXP software and linked with national registries. Bespoke rule-based algorithms were applied to describe Tx patterns; Kaplan–Meier methods were used to estimate OS. Results: 2779 pts were diagnosed with incident NSCLC (median age, 70 yrs [range: 22–96; 14.2% ≥80]; male, 48.5%; histology: non-squamous (NSQ), 70.9%, squamous (SQ), 17.7%, other, 11.4%; stage distribution: I, 19.3%; II, 7.7%; IIIA, 12.3%; IIIB, 7.2%; IV, 51.2%). Initial Tx (≤6 months from diagnosis) by stage and yr of diagnosis is shown in the table. Median OS (months) for NSQ and SQ pts: not reached and 52.8 in stage I, 43.2 and 23.6 in stage II, 26.7 and 20.4 in stage IIIA, 12.5 and 12.9 in stage IIIB, and 7.6 and 6.1 in stage IV, respectively. Among stage IIIB–IV pts, 60.7% (NSQ) and 53.5% (SQ) had ≥1 line of systemic anti-cancer therapy (SACT); median OS was 12.2 (NSQ) and 10.4 (SQ) months in pts on SACT, and 3.1 (NSQ) and 3.7 (SQ) months in pts not on SACT. Ongoing analyses will assess factors associated with SACT receipt in stage IIIB–IV pts. Conclusions: Swedish pts with NSCLC had a high burden of disease, with most diagnosed at stage IV and a median OS of 1 yr in late-stage pts receiving SACT. There is also scope for improved prognosis in pts diagnosed at early stages, particularly in SQ pts. Future analyses will assess the potential impact of recent improvements in diagnostics and therapeutics on Tx patterns and OS in Swedish NSCLC pts.

Tidskriftsartikel (refereegranskat)abstract
- The objective of the present longitudinal descriptive study was to extend previous observations on the benefit of in-vitro fertilization (IVF) in cases of anejaculatory infertility due to spinal cord injuries (SCI) and to report results achieved by intracytoplasmic sperm injection (ICSI). The study was performed in a national referral unit for SCI, Spinalis SCI Research Unit, the Karolinska Institute. The patient material consisted of couples with SCI men seeking treatment for their infertility. The inclusion criteria were: stable relationship, motile spermatozoa in a diagnostic sample and no female contraindications. Spermatozoa were retrieved through electroejaculation or vibratory stimulation. If the sperm quality was judged to be sufficient, standard IVF was performed. ICSI was employed if the semen quality was extremely poor. We have treated 25 couples in 52 cycles, leading to 81 ovum retrievals and 47 embryo transfers. Total sperm counts were very variable (0.01-978 x 10(6)). Before the introduction of ICSI the fertilization rate was 30%. ICSI increased the fertilization rate to 88%. There was no association between the pregnancy rate and the sperm count, level of injury or fertilization technique. A total of 16 clinical pregnancies was established, leading to 11 deliveries. This gives a cumulative pregnancy rate per couple of 56%.

- We conducted an epidemiological, observational cohort study to determine the incidence and complications of acute otitis media (AOM) in children aged <6 years. Data on physician-diagnosed AOM were collected from retrospective review of medical charts for the year preceding enrolment and then prospectively in the year following enrolment. The study included 5776 children in Germany, Italy, Spain, Sweden, and the UK. AOM incidence was 256/1000 person-years [95% confidence interval (CI) 243-270] in the prospective study period. Incidence was lowest in Italy (195, 95% CI 171-222) and highest in Spain (328, 95% CI 296-363). Complications were documented in < 1% of episodes. Spontaneous tympanic membrane perforation was documented in 7% of episodes. Both retrospective and prospective study results were similar and show the high incidence during childhood in these five European countries. Differences by country may reflect true differences and differences in social structure and diagnostic procedures.

- BACKGROUND: Oily fish provides marine n-3 (omega-3) fatty acids that are considered to be important in the growth, development, and health of the fetus and newborn infant. OBJECTIVES: The objectives were to increase salmon consumption among pregnant women and to determine the effect on maternal and umbilical cord plasma marine n-3 fatty acid content. DESIGN: Women (n = 123) with low habitual consumption of oily fish were randomly assigned to continue their habitual diet or were provided with 2 portions of farmed salmon/wk to include in their diet from week 20 of pregnancy until delivery. RESULTS: Median weekly consumption frequency of study salmon in the salmon group was 1.94 portions, and total fish consumption frequency was 2.11 portions/wk in the salmon group and 0.47 portions/wk in the control group (P < 0.001). Intakes of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) from the diet, from seafood, and from oily fish were higher in the salmon group (all P < 0.001). Percentages of EPA and DHA in plasma phosphatidylcholine decreased during pregnancy in the control group (P for trend = 0.029 and 0.008, respectively), whereas they increased in the salmon group (P for trend for both < 0.001). EPA and DHA percentages were higher in maternal plasma phosphatidylcholine at weeks 34 and 38 of pregnancy and in umbilical cord plasma phosphatidylcholine in the salmon group (P < 0.001 for all). CONCLUSION: If pregnant women, who do not regularly eat oily fish, eat 2 portions of salmon/wk, they will increase their intake of EPA and DHA, achieving the recommended minimum intake; and they will increase their and their fetus' status of EPA and DHA. This trial was registered at clinicaltrials.gov as NCT00801502.

Tidskriftsartikel (refereegranskat)abstract
- MicroRNA-371a-3p (miR371) has been suggested as a sensitive biomarker in testicular germ cell cancer (TGCC). We aimed to compare miR371 with the classical biomarkers α-fetoprotein (AFP) and β-human chorionic gonadotropin (hCGβ). Overall, 180 patients were prospectively enrolled in the study, with serum samples collected before and after orchiectomy. We compared the use of digital droplet PCR (RT-ddPCR) with the quantitative PCR used by others for detection of miR371. The novel RT-ddPCR protocol showed high performance in detection of miR371 in serum samples. In the study cohort, miR371 was measured using RT-ddPCR. MiR371 detected CS1 of the seminoma and the non-seminoma sub-types with a sensitivity of 87% and 89%, respectively. The total sensitivity was 89%. After orchiectomy, miR371 levels declined in 154 of 159 TGCC cases. The ratio of miR371 pre- and post-orchiectomy was 20.5 in CS1 compared to 6.5 in systemic disease. AFP and hCGβ had sensitivities of 52% and 51% in the non-seminomas. MiR371 is a sensitive marker that performs better than the classical markers in all sub-types and clinical stages. Especially for the seminomas CS1, the high sensitivity of miR371 in detecting TGCC cells may have clinical implications.

Tidskriftsartikel (refereegranskat)abstract
- An increased risk for myocardial infarction (MI) related to environmental tobacco smoke (ETS) exposure has previously been reported, but several aspects of the association are still uncertain. We studied the MI risk associated with ETS exposure among 334 nonfatal never-smoking MI cases and 677 population controls, 45-70 years of age, in Stockholm County. A postal questionnaire with a telephone follow-up provided information on ETS exposure and other potential risk factors for MI. After adjustment for age, gender, hospital catchment area, body mass index, socioeconomic status, job strain, hypertension, diet, and diabetes mellitus, the odds ratio for MI was 1.58 (95% confidence interval = 0.97-2.56) for an average daily exposure of 20 cigarettes or more from the spouse. Combined exposure from spouse and work showed an increasing odds ratio for MI, up to 1.55 (95% confidence interval = 1.02-2.34) in the highest category of weighted duration, that is, more than 90 "hour-years" of exposure (1 "hour-year" = 365 hours, or 1 hour per day for 1 year). In addition, more recent exposure appeared to convey a higher risk. Our data confirm an increased risk of MI from exposure to ETS and suggest that intensity of spousal exposure, combined exposure from spouse and work, and time since last exposure are important.
