- 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.

- 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%.
