Psychological distress following cancer diagnosis may lead to mental health complications including depression and anxiety. Non-Hodgkin lymphomas (NHLs) include indolent and aggressive subtypes for which treatment and prognosis differ widely.Incident use of psychotropic drugs (PDs-antidepressants, antipsychotics, and anxiolytics) and its correlation to lymphoma types can give insights into the psychological distress these patients endure. In this prospective matched cohort study, we used nationwide population-based registries to investigate the cumulative risk of PD use in NHL patients compared to a sex-and age-matched cohort from the Danish

Background Obesity and metabolic syndrome (MetS) are major risk factors for atherosclerotic diseases; however, a causal link remains elusive. Animal models resembling human MetS and its complications, while important, are scarce. We aimed at developing a porcine model of human MetS. Methods Forty pigs with familial hypercholesterolemia were fed a high fat + fructose diet for 30 weeks. Metabolic assessments and subcutaneous fat biopsies were obtained at 18 and 30 weeks, and fat distribution was assessed by CT-scans. Postmortem, macrophage density, and phenotype in fat tissues were quantified along with atherosclerotic burden. Results During the experiment, we observed a >4-fold in body weight, a significant but small increase in fasting glucose (4.1 mmol/L), insulin (3.1 mU/L), triglycerides (0.5 mmol/L), and HDL cholesterol (2.6 mmol/L). Subcutaneous fat correlated with insulin resistance, but intra-abdominal fat correlated inversely with insulin resistance and LDL cholesterol. More inflammatory macrophages were found in visceral versus subcutaneous fat, and inflammation decreased in subcutaneous fat over time. Conclusions MetS based on human criteria was not achieved. Surprisingly, visceral fat seemed part of a healthier metabolic and inflammatory profile. These results differ from human findings, and further research is needed to understand the relationship between obesity and MetS in porcine models.

Peripheral T-Cell Lymphomas (PTCLs) are rare, aggressive lymphomas with poor outcomes, but limited-stage disease is infrequent and not well-described. This study reports outcomes and prognostic factors in limited-stage nodal PTCLs in a binational population-based setting. Patients were identified from the Danish and Swedish lymphoma registries. Adults diagnosed with limited-stage nodal PTCL (stage I-II) and treated with CHOP(Àlike) therapy ±radiotherapy between 2000 and 2014 were included. Medical records were reviewed by local investigators. A total of 239 patients with a median age of 62 years were included; 67% received 6-8 cycles of CHOP(Àlike) therapy and 22% received 3-4 cycles, of which 59% also received radiotherapy. Autologous stem cell transplant consolidation was administered to 16% of all patients. Median follow-up was 127 months with 5-years overall survival (OS) of 58% (95% CI: 53-65) and progression-free survival (PFS) of 53% (95% CI: 47-59). In multivariable analysis, age ≥ 60 years and B-symptoms were unfavorable and ALK+ anaplastic large cell T-Cell lymphoma was favorable for survival outcomes.There was no difference in treatment-specific outcome (3-4 cycles vs. 6-8 cycles of CHOP(Àlike) ± radiotherapy). Low-risk patients (age < 60 without B-symptoms) had a 5-year OS of 77% (95% CI 67-89%). In the present study of limited-stage nodal PTCL, survival after curative intent chemotherapy +/À radiotherapy was inferior to that of limited-stage diffuse large B-cell lymphoma, but a subgroup of young patients Ahmed Ludvigsen Al-Mashhadi and Henrik Cederleuf contributed equally. Fredrik Ellin and Tarec Christoffer El-Galaly contributed equally.

Introduction: A cancer diagnosis is associated with profound psychological distress that potentially can lead to mental health problems such as depression and anxiety. Non-Hodgkin lymphomas (NHLs) are a heterogenous group of indolent and aggressive cancer diseases with high variability in treatment selections and patient outcomes. Some patients are chronically ill with recurrent need for mild chemotherapy whereas others face immediately life-threatening, yet curable disease. To gain valuable insights into the psychological distress associated with NHLs, the present study investigated the incident psychotropic drug (PD - antidepressants, anxiolytics, and antipsychotics) use, contact patterns to psychiatric departments, and intentional self-harm (including suicide) in Danish NHL patients relative to sex- and age matched individuals from the background population. Methods: The study was carried out as a nationwide population-based matched cohort study based on prospectively collected data from several Danish registries. All adult NHL patients (≥18 years) diagnosed between 2005 and 2015 were identified in the Danish Lymphoma Registry and included if they had not been treated with any kind of PD within the last 10 years prior to date of NHL diagnosis (index date). NHL patients were matched on age and sex with five random comparators from the Danish background population on the index date. Comparators had to be alive and without PD use 10 years prior to the index date. Incident PD use was defined as first redeemed prescription of PD after index date. Prescriptions were captured in the National Prescription Registry and described by cumulative incidences using the Aalen-Johansen estimator with death and NHL relapse as competing risk. Contacts with psychiatric departments and registration of intentional self-harm or completed suicide were captured in the Danish National Patient Registry. Patients were subcategorized according to type of lymphoma (Table 1). Results: In total, 7,201 NHL patients and 36,005 matched comparators were included (median follow-up 7.1 years). Follicular lymphoma (FL, 44.4%) and diffuse large B-cell lymphoma (DLBCL, 41.0%) were the most common subtypes (Table 2). Two-year cumulative incidence of PD use was higher in NHL patients overall (16.2%, 95%CI 15.4-17.0%) compared to matched comparators (5.7%, 95%CI 5.5-5.9%). Patients with aggressive NHL subtypes tended to have the highest incidence of PD use (Figure 1). Antidepressants (two-year cumulative incidence, 9.0%, 95%CI 8.4-9.6) and anxiolytics (8.2%, 95%CI 7.6-8.8) were the most used PDs in all NHL subtypes. The risk of PD use was higher in the first years following diagnosis, but except for patients with indolent NHL subtypes, the risk of PD use normalized over time to that of the background population. As for the risk of any psychiatric department contacts, there was no difference in two-year cumulative incidences between NHL patients (range 0.6-0.9%) and the matched comparators (range 0.6%-0.9%), whereas the two-year cumulative incidence of intentional self-harm and suicide was slightly higher for NHL patients (0.3%) compared to the matched comparators (0.2%, p=0.01). Conclusion: This study suggests that NHL patients have a significantly higher risk of mental health problems compared to the Danish background population, (when) using PD prescriptions as a proxy measure. The risk of intentional self-harm and completed suicide was also higher, but numerical differences were very small. Overall, the results emphasize the need for directing clinical attention on mental health in newly diagnosed NHL patients and screening for relevant symptoms during follow-up to provide best possible support to patients suffering from anxiety and depression.
