OptiVol (Medtronic PLC, Minneapolis, MN) is a diagnostic feature of some cardiac implantable electronic devices (CIEDs) based on changes in thoracic impedance (TI) over time. Changes in TI can predict heart failure (HF) hospitalizations and mortality in HF populations. However, the utility of this feature is unknown in patients with a left ventricular assist device (LVAD). read more To determine if OptiVol and TI correlate with clinical HF events in a population of LVAD patients, hospitalization outcomes were collected retrospectively from the electronic health records at a single academic medical center in 80 LVAD patients with an OptiVol-capable CIED. Demographics, medical history, and available clinical data were reviewed and reported. The primary outcomes of interest were TI and OptiVol trends before and after hospitalization, and association of trends before and after these events was evaluated. Most patients had a HeartMate II LVAD and most CIEDs were defibrillators, and 23 (29%) had at least one HF hospitalization during the study period. HF hospitalizations were preceded by signs of volume overload in Optivol (60%) and TI (78%) with recovery of these measures post hospitalization in 33% and 25% of patients, respectively. Monitoring of TI and OptiVol may be one effective component of HF management in LVAD patients as part of a comprehensive program.Despite the common occurrence of brain injury in patients with left ventricular assist device (LVAD), optimal neuromonitoring methods are unknown. A systematic review of PubMed and six electronic databases from inception was conducted until June 5, 2019. Studies reporting methods of neuromonitoring while on LVAD were extracted. Of 5,190 records screened, 37 studies met the inclusion criteria. The neuromonitoring methods include Transcranial Doppler ultrasound for emboli monitoring (TCD-e) (n = 13) and cerebral autoregulation (n = 3), computed tomography and magnetic resonance imaging (n = 9), serum biomarkers (n = 7), carotid ultrasound (n = 3), and near-infrared spectroscopy (n = 2). Of 421 patients with TCD-e, thromboembolic events (TEs) were reported in 79 patients (20%) and microembolic signals (MES) were detected in 105 patients (27%). Ischemic stroke was more prevalent in patients with MES compared to patients without MES (43% vs.13%, p less then 0.001). Carotid ultrasound for assessing carotid stenosis was unreliable after LVAD implantation. Elevated lactate dehydrogenase (LDH) levels were associated with TEs. Significant heterogeneity exists in timing, frequency, and types of neuromonitoring tools. TCD-e and serial LDH levels appeared to have potential for assessing the risk of ischemic stroke. Future prospective research incorporating protocolized TCD-e and LDH may assist in monitoring adverse events in patients with LVAD.The management of infants with congenital diaphragmatic hernia (CDH) receiving extracorporeal life support (ECLS) is complex. Significant variability in both practice and prevalence of ECLS use exists among centers, given the lack of evidence to guide management decisions. The purpose of this report is to review existing evidence and develop management recommendations for CDH patients treated with ECLS. This article was developed by the Extracorporeal Life Support Organization CDH interest group in cooperation with members of the CDH Study Group and the Children's Hospitals Neonatal Consortium.
Age-related macular degeneration (AMD) is one of the most common causes of severe vision loss in the developed world. Advanced forms of AMD are seen in primarily 2 types, exudative AMD involving the presence of choroidal neovascularization and nonexudative or dry AMD with geographic atrophy. For the latter, the combination of vitamins and minerals known as the Age-Related Eye Disease Study-2 formulation has been shown to decrease the rate of progression of nonexudative to exudative AMD, as no other treatments are currently approved for nonexudative AMD. This review will highlight upcoming treatments for nonexudative AMD. Six upcoming agents have shown results at least in the 2A phase. This includes intravitreal agents that are inhibitors of integrin (Risuteganib), intravitreal agents that disrupt the complement pathway (Zimura, APL-2), neuroprotective implants (Brimonidine DDS), a subcutaneous injectable (Elamipretide), and photobiomodulation (Valeda Light Delivery System).

Fatigue is one of the most common adverse events of systemic therapy in patients with metastatic renal cell carcinoma (RCC). The aim of multicenter randomized phase 2 study was to determine the efficacy and safety of testosterone in patients with fatigue developed during targeted therapy.

Male patients with metastatic clear-cell RCC, normal prostate-specific antigen level, low testosterone level, and no evidence of hypothyroidism receiving first-line sunitinib or pazopanib with fatigue were randomly assigned (11) to either testosterone undecanoate (1000 mg) and targeted therapy or targeted therapy alone. The primary endpoint was the mean change of fatigue from baseline to 28 days according to the Functional Assessment of Chronic Illness Therapy-Fatigue scale. Secondary endpoints were safety, Functional Assessment of Cancer Therapy-Kidney Symptom Index 19, testosterone serum concentrations, red blood cell count, and hemoglobin level.

Sixty patients were assigned to receive testosterone and targeted therapy (N=30) or targeted therapy alone (N=30).
