    Here we summarise the biopsy approach to amyloidosis, as well as the non-biopsy diagnosis of cardiac transthyretin amyloidosis. Proteomic and antibody-based methods for amyloid subtyping are reviewed. Finally, an algorithm for confirming the diagnosis of amyloidosis is presented.Introduction It is established that anemia leads to adaptive changes in cardiac geometry including left ventricular hypertrophy (LVH). However, published data are still scarce regarding the association of LVH with normal-range hemoglobin levels. Objective To evaluate the association between hemoglobin level and LVH in subjects with or without anemia. Methods The study included 48,034 Korean men and women who received echocardiography during their medical health checkup. They were divided into 4 groups according to their hemoglobin concentration (g/dL) in men ( less then 14, 14-14.9, 15-15.9, and ≥16) and women ( less then 12, 12-12.9, 13-13.9, and ≥15). Multivariate logistic regression analysis was used to calculate adjusted ORs and 95% CI for LVH in each group compared with the group with the lowest hemoglobin. Subgroup analysis was conducted for subjects within normal hemoglobin levels. Results There was an inverse relationship between hemoglobin levels and LVH, where unadjusted and adjusted ORs and 95% CI for LVH decreased with increasing hemoglobin levels in both men and women. In subgroup analysis, this inverse relationship was also observed in subjects with hemoglobin in the nonanemic range. Conclusion The decrease in hemoglobin was significantly associated with the increased probability of LVH, and this association was found even in nonanemic subjects.Introduction Macular pigment optical density plays a pivotal role in maintaining macular structure and functioning. Research shows that daily consumption of lutein reduces the risk of eye diseases such as age-related macular degeneration. Objective This study analyzes the influence of a supplementation containing lutein and antioxidant vitamins either with or without docosahexaenoic acid (DHA), with the main objective of identifying macular pigment optical density (MPOD) changes in both eyes at the end of the follow-up using the Visucam® retinograph. The secondary endpoint was to determine variation in the lutein and DHA levels in plasma and red blood cell membranes respectively. Methods One hundred healthy participants (200 eyes) aged 40-70 years (mean age 49.3 years, SEM=13.7) were randomized in a 11 ratio to receive daily one of the following supplements for 3 months Lutein group (LT-G, n=49), Lutein /Docosahexaenoic acid group (LT/DHA-G, n= 51). The MPOD was measured at baseline and end of the follow-up by retinography (Visucam® retinograph). Lutein in plasma was determined by HPLC and DHA in red blood cell membranes was analyzed by gas chromatograph/mass spectrometer. Results From baseline, macular pigment optical density showed significantly higher values in the Lutein/DHA group than in the Lutein group at the end of the study (p less then 0.0001). Significantly higher Lutein in plasma (p less then 0.0001) and DHA (p less then 0.0001) levels in the red blood cell membrane were seen in the Lutein/DHA group than in the Lutein group at the 3-month follow-up. Conclusion Lutein supplementation improves macular pigment optical density in healthy subjects from a Mediterranean population being significantly increased in the presence of DHA. Therefore, our findings highlight the relevance of the adjunctive role of DHA for a better Lutein availability.Background Cerebral infarction caused by pituitary apoplexy (PA) is rare. To characterize the clinical features of cerebral infarction caused by PA, we performed a systematic review. Summary The clinical symptoms are mainly sudden headache, hemiplegia, visual impairment, disturbance of consciousness, and ophthalmalgia in patients with cerebral infarction caused by PA. Treatment for this type of infarction is different from treatment for general acute cerebral infarction. Compared to patients who underwent emergency surgery and conservative treatment, patients treated with delayed surgery showed a better prognosis and a lower mortality rate. Compared to patients who underwent craniotomy or conservative treatment, patients who underwent transsphenoidal surgery (TSS) not only improved well but also showed a lower mortality rate. Key Messages PA rarely causes cerebral infarction, which is a critical condition with a poor prognosis and is more common in men. Delayed surgery and TSS appear to confer a better prognosis in patients with this condition.Introduction Evidence on effects of Internet-based interventions to treat subthreshold depression (sD) and prevent the onset of major depression (MDD) is inconsistent. Objective We conducted an individual participant data meta-analysis to determine differences between intervention and control groups (IG, CG) in depressive symptom severity (DSS), treatment response, close to symptom-free status, symptom deterioration and MDD onset as well as moderators of intervention outcomes. Methods Randomized controlled trials were identified through systematic searches via PubMed, PsycINFO, Embase and Cochrane Library. Selleck 5-FU Multilevel regression analyses were used to examine efficacy and moderators. Results Seven trials (2,186 participants) were included. The IG was superior in DSS at all measurement points (posttreatment 6-12 weeks; Hedges’ g = 0.39 [95% CI 0.25-0.53]; follow-up 1 3-6 months; g = 0.30 [95% CI 0.15-0.45]; follow-up 2 12 months, g = 0.27 [95% CI 0.07-0.47], compared with the CG. Significantly more participants in the IG than in the CG reached response and close to symptom-free status at all measurement points. A significant difference in symptom deterioration between the groups was found at the posttreatment assessment and follow-up 2. Incidence rates for MDD onset within 12 months were lower in the IG (19%) than in the CG (26%). Higher initial DSS and older age were identified as moderators of intervention effect on DSS. Conclusions Our findings provide evidence for Internet-based interventions to be a suitable low-threshold intervention to treat individuals with sD and to reduce the incidence of MDD. This might be particularly true for older people with a substantial symptom burden.
