Heart failure (HF), the leading cause of death in developed countries, occurs in the setting of reduced (HFrEF) or preserved (HFpEF) ejection fraction. Unlike HFrEF, there are no effective treatments for HFpEF, which accounts for ∼50% of heart failure. Abnormal intracellular calcium dynamics in cardiomyocytes have major implications for contractility and rhythm, but compared to HFrEF, very little is known about calcium cycling in HFpEF. We used rat models of HFpEF and HFrEF to reveal distinct differences in intracellular calcium regulation and excitation-contraction (EC) coupling. While HFrEF is characterized by defective EC coupling at baseline, HFpEF exhibits enhanced coupling fidelity, further aggravated by a reduction in β-adrenergic sensitivity. These differences in EC coupling and β-adrenergic sensitivity may help explain why therapies that work in HFrEF are ineffective in HFpEF.

Heart failure with reduced or preserved ejection fraction (respectively, HFrEF and HFpEF) is the leading cause of death iefective couplon recruitment, associated with transverse (t)-tubule disruption. In stark contrast, HFpEF cardiomyocytes showed saturated EC coupling (increased ICa , high probability of couplon recruitment with greater Ca2+ release synchrony, increased CaT) and preserved t-tubule integrity. β-Adrenergic stimulation of HFpEF myocytes with isoprenaline (isoproterenol) failed to elicit robust increases in ICa or CaT and relaxation kinetics. Fundamental differences in EC coupling distinguish HFrEF from HFpEF.Tilapia lake virus (TiLV) is a highly contagious pathogen that has detrimental effects on tilapia farming. This virus was discovered in 2014 and has received tremendous global attention from the aquaculture sector due to its association with high fish mortalities and its strong economic impact on the tilapia aquaculture industry. Currently, TiLV has been reported in 16 countries, and this number is continuing to rise due to improved diagnostic assays and surveillance activities around the world. In this review, we summarize the up-to-date knowledge of TiLV with regard to TiLV host species, the clinical signs of a TiLV infection, the affected tissues, pathogenesis and potential disease risk factors. We also describe the reported information concerning the virus itself its morphology, genetic make-up and transmission pathways. We review the current methods for virus detection and potential control measures. We close the review of the TiLV story so far, by offering a commentary on the major TiLV research gaps, why these are delaying future TiLV research and why the TiLV field needs to come together and proceed as a more collaborative scientific community if there is any hope limiting the impact of this serious virus.By keeping tropical shrimp, like Litopenaeus vannamei, in recirculating aquaculture systems (RAS), valuable food for human consumption can be produced sustainable. L. vannamei tolerates low salinities, and therefore, the systems can operate under brackish water conditions. The stabilization of the microbial community in RAS might be difficult under high organic loads, and therefore, water treatment measures like UV irradiation or ozone application are commonly used for bacterial reduction. To investigate the impact of these measures, the effects of UV irradiation and ozone application were studied in small-scale brackish water RAS with a salinity of 15‰ stocked with L. vannamei. UV reactors with 7 and 9 W were used, and by ozonizers with a power of 5-50 mg/hr, the redox potential in the water was adjusted to 350 mV. Ozone had a stabilizing effect on the microbial composition in the water and on biofilms of tank surfaces and shrimp carapaces, prevented an increase of nitrite and accelerated the degradation of nitrate in the water. UV irradiation led to changes in the microbial composition and was less effective in optimizing the chemical water quality. Thus, the use of ozone could be recommended for water treatment in brackish water RAS for shrimp.Intestinal failure-associated liver disease (IFALD) can lead to increased morbidity and mortality in patients with intestinal failure (IF). We report the case of a premature infant born at 25 weeks’ gestation at a neighboring facility that developed surgical necrotizing enterocolitis and secondary IF with 6 cm of small bowel remaining measured from the ligament of treitz with jejunocolonic anastomosis. The patient’s course was complicated by IFALD and transferred to our intestinal rehabilitation program at 3 months of age. He was treated with SMOF lipid in reduced lipid dosages to prevent and treat IFALD, including cycling of parenteral nutrition, monitoring of the glucose infusion rate, and adjusting the micronutrient, trace elements, and aggressive enteral feeding. Omegaven had not yet been approved during the time of this case presentation. During the course of his treatment, he experienced normalization of his liver profile tests and progressed toward enteral autonomy.The purpose of this study was to review adherence rates to intravitreal injections in the treatment of diabetic macula oedema and to identify factors associated with adherence. A systematic search of Embase, Medline, PsycINFO and CINAHL was conducted up to May 2020. Two authors independently screened, selected and appraised the studies. Seven articles on anti-VEGF treatment were found to meet the inclusion criteria. No studies were found on intravitreal corticosteroids or dexamethasone implants. Attendance rates varied between studies from 35% to 85%. The rate of missed or delayed attendance ranged from 14% to 51%, whereas 25% of patients were lost to follow-up at 12 months. Non-adherence was found to be multifactorial and included patient related reasons, demographic characteristics and clinical factors. Enablers to adherence included patient understanding of the disease and treatment. Further research in this area is warranted in order to better understand adherence in these patients and to improve patient outcomes.Striped marlin Kajikia audax are globally Near Threatened and their stock in the Indian Ocean was last assessed as „overfished and subject to overfishing”. Significant gaps in our understanding of their ecology remain, hampering the efforts of fisheries managers to ensure stock sustainability. There is a particular lack of fisheries-independent data. Here we present the results from the first large-scale satellite tracking study of K. audax in the Indian Ocean. We tagged 49 K. audax with pop-up archival satellite-linked tags off the Kenyan coast from 2015 to 2019. Individuals were highly mobile, covering horizontal distances of up to 9187 km over periods ranging up to 183 days, with a mean daily distance of ~48 km. Long-distance movements were recorded to the east and north of East Africa, with the most distant tracks extending north to the Arabian Sea and east to near the Maldives. None of the K. audax swam south of East Africa. Kernel utilization distributions of fish locations demonstrated their shifting seasonal activity hotspots. Over the sport-fishing season (and tagging period) in Kenya, from December to March, K. audax typically stayed off the East African coast. After March, the activity hotspot shifted north to a region close to the Horn of Africa and Socotra Island. Remotely sensed sea surface temperature and chlorophyll-a maps indicated that this seasonal movement could be driven by a shift in prey availability. Our results show the high mobility of K. audax in the Western Indian Ocean, and that individuals seasonally range between two major fishing areas.Acute urinary retention (AUR) is one of the progressive manifestations of benign prostatic hyperplasia (BPH). This cross-sectional study was conducted to analyse the possible association between serum interleukin 8 (sIL-8) and AUR in BPH patients to provide evidence of sIL-8 as a potential biomarker for the prediction of AUR. The relationship between sIL-8 levels and AUR was evaluated by logistic regressions in 245 ageing Chinese men with BPH. The discriminant validity of sIL-8 and the optimal cut-off value were determined by a receiver operating characteristic curve. The levels of sIL-8 increased significantly in BPH patients with AUR (p less then 0.001). The sIL-8 concentration was positively correlated with AUR in BPH patients (OR = 1.024, 95% CI 1.009-1.040, p = 0.002). The correlation with AUR in the group with a high sIL-8 level (≥43.05 pg/ml) was significantly enhanced (OR = 8.853, 95% CI 2.433-32.205, p = 0.001). The sIL-8 level correlated with AUR in Chinese BPH patients independently. As a possible predictor, sIL-8 may contribute to the screening of high-risk populations for AUR to create opportunities for the early effective interventions to improve prognosis and enhance the quality of life. Prospective studies are needed to support all these results.

According to international guidelines and literature, all patients with intermittent claudication should receive an initial treatment of cardiovascular risk modification, lifestyle coaching, and supervised exercise therapy. In the literature, supervised exercise therapy often consists of treadmill or track walking. However, alternative modes of exercise therapy have been described and yielded similar results to walking. This raises the following question which exercise mode produces the most favourable results? This is the first update of the original review published in 2014.

To assess the effects of alternative modes of supervised exercise therapy compared to traditional walking exercise in patients with intermittent claudication.

The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 4 March 20 bias concerns. The findings of this review indicate that alternative exercise modes may be useful when supervised walking exercise is not an option. More RCTs with adequate methodological quality and sufficient power are needed to provide solid evidence for comparisons between each alternative exercise mode and the current standard of supervised treadmill walking. Future RCTs should investigate outcome measures on walking behaviour, physical activity, cardiovascular risk, and HR-QoL, using standardised testing methods and reporting of outcomes to allow meaningful comparison across studies.
