BACKGROUND International guidelines advise universal beta blocker therapy as either a class I (symptomatic or QTc > 470 ms) or class II recommendation (asymptomatic and QTc less then 470 ms) in the treatment of Long QT Syndrome (LQTS). OBJECTIVE This study sought to evaluate the outcomes of a highly selected cohort of patients with LQTS managed with an observation only (intentional non-treatment) strategy. METHODS The cohort was derived using a comprehensive retrospective registry of patients with LQTS. Clinical phenotype and genotype data were collected via review of the electronic health record. RESULTS Among 661 patients with LQTS, 55 (8.3%) heretofore asymptomatic patients (53% female, 16 patients less then 18 years of age) were managed with intentional non-therapy. Only preventative measures were advised. The mean age at diagnosis was 37.8 + 21.2 years and the mean QTc was 448 + 30 ms. None of the patients experienced a LQTS-triggered cardiac event over the mean 7.5 + 4.3 year follow-up period. Compared to the larger treated cohort, this intentionally untreated cohort was less symptomatic, older at diagnosis, and had lower resting QTc values (p less then 0.0001). CONCLUSION Following careful clinical evaluation, risk assessment, and institution of precautionary measures, an observation-only strategy may be considered in a highly selected group of LQTS patients with a clinical profile including asymptomatic status, older age at diagnosis, and QTc less then 470 ms with excellent outcomes and a better quality of life than beta-blocked LQTS patients. LQTS patients with this low-risk profile should not receive a prophylactic ICD. The retinal pigment epithelium (RPE), a monolayer of post-mitotic polarized epithelial cells, strategically situated between the photoreceptors and the choroid, is the primary caretaker of photoreceptor health and function. Dysfunction of the RPE underlies many inherited and acquired diseases that cause permanent blindness. Decades of research have yielded valuable insight into the cell biology of the RPE. In recent years, new technologies such as live-cell imaging have resulted in major advancement in our understanding of areas such as the daily phagocytosis and clearance of photoreceptor outer segment tips, autophagy, endolysosome function, and the metabolic interplay between the RPE and photoreceptors. find more In this review, we aim to integrate these studies with an emphasis on appropriate models and techniques to investigate RPE cell biology and metabolism, and discuss how RPE cell biology informs our understanding of retinal disease. BACKGROUND CONTEXT Although vertebral augmentation with bone cement has been commonly used to treat symptomatic osteoporotic vertebral compression fractures, relatively little is known about the impact of augmentation on the adjacent spinal components. PURPOSE To determine the imaging effects of vertebral augmentation on the adjacent discs, the augmented vertebra, and the involved spinal segment. STUDY DESIGN Retrospective radiographic study. PATIENT SAMPLE Patients with acute osteoporotic vertebral compression fractures who underwent vertebral augmentation or nonoperative treatments. OUTCOME MEASURES On baseline and follow-up mid-sagittal T2W magnetic resonance images, quantitative measurements of disc degeneration, including disc height, bulging, and signal, vertebral height, wedge angle, and segmental kyphotic angle were acquired. METHODS Lumbar spine magnetic resonance images of patients with acute osteoporotic vertebral compression fractures at a local hospital in Eastern China between 2010 and 2017 wereental kyphotic angle significantly increased in vertebral fractures that underwent vertebral augmentation (p less then 0.001), but not in those underwent nonoperative treatments. CONCLUSIONS Patients that underwent vertebral augmentation had more advanced disc degeneration at adjacent disc levels as compared to those without augmentation. The fractured vertebral body height decreased and the wedge angle increased, regardless of vertebral augmentation treatment or not. Vertebral augmentation may be associated with increased creep deformity of the adjacent vertebra and the progression of segmental kyphosis. γ-Aminobutyric acid (GABA) generally induces hyperpolarization and inhibition in the adult brain, but causes depolarization (and can be excitatory) in the immature brain. Depolarizing GABA actions are necessary for neurogenesis, differentiation, migration, and synaptogenesis. Additionally, the conversion of GABA responses from inhibition to excitation can be induced in adults by pathological conditions. Because GABAA receptors are Cl- channels, alternating GABA actions between hyperpolarization (Cl- influx) and depolarization (Cl- efflux) are induced by changes in the Cl- gradient, which is regulated by Cl- transporters. Thus, the dynamics of neural functions are modulated by active Cl- homeostasis (Cl- homeodynamics), alternating inhibition and excitation, and could underlie the modal shifts in cellular and network oscillations. Such a modal shift in GABA actions is required for normal development. Thus disturbances in this developmental GABA modal shift and/or the induction of excitatory GABA action could underlie the pathogenesis of diverse neurological diseases (so-called network diseases). V.Primary care physicians are uniquely placed to offer holistic, patient-centred care to patients with T2DM. While the recent FDA-mandated cardiovascular outcome trials offer a wealth of data to inform treatment discussions, they have also contributed to increasing complexity in treatment decisions, and in the guidelines that seek to assist in making these decisions. To assist physicians in avoiding treatment inertia, Primary Care Diabetes Europe has formulated a position statement that summarises our current understanding of the available T2DM treatment options in various patient populations. New data from recent outcomes trials is contextualised and summarised for the primary care physician. This consensus paper also proposes a unique and simple tool to stratify patients into 'very high' and 'high' cardiovascular risk categories and outlines treatment recommendations for patients with atherosclerotic cardiovascular disease, heart failure and chronic kidney disease. Special consideration is given to elderly/frail patients and those with obesity.
