Rebecca Brake, Ian David Jones
Chronic heart failure is a common and complex clinical syndrome that results from impaired cardiac relaxation or contraction. Patients with chronic heart failure may experience multiple debilitating symptoms, such as fatigue, pain, and peripheral oedema. However, breathlessness may be considered the most debilitating symptom. This is the first of two articles on chronic heart failure, and outlines the pathophysiology of the condition, its causes, assessment, and signs and symptoms. Part 2 will discuss the treatment and management of the condition, including pharmacological strategies, device implantation, lifestyle modification, cardiac rehabilitation and palliative care...

A new wave of portable biosensors allows frequent measurement of health-related physiology. We investigated the use of these devices to monitor human physiological changes during various activities and their role in managing health and diagnosing and analyzing disease. By recording over 250,000 daily measurements for up to 43 individuals, we found personalized circadian differences in physiological parameters, replicating previous physiological findings. Interestingly, we found striking changes in particular environments, such as airline flights (decreased peripheral capillary oxygen saturation [SpO2] and increased radiation exposure)...

PURPOSE: Ratings of perceived exertion (RPE) may be useful for exercise testing and prescription in individuals with spinal cord injury (SCI), though the roles of differentiated central and peripheral fatigue during exercise are not clear. We aimed to model differentiated RPE responses during graded arm cycling in individuals with SCI and describe their relationship to cardiorespiratory outcomes. METHODS: Thirty-six individuals with SCI (13 paraplegia; 23 tetraplegia) completed a maximal graded-arm cycling exercise test to volitional exhaustion (5W/min paraplegia; 10W/min tetraplegia)...

A significant unmet need exists in patients with relapsed or refractory multiple myeloma (MM), which remains an incurable disease despite recent advances in the field. One such development was the use of deacetylase inhibitors (DACi), which exert unique antimyeloma effects through targeting of epigenetic and protein metabolism pathways. The pan-DACi panobinostat was recently approved in combination with bortezomib and dexamethasone for use in patients with relapsed or relapsed and refractory MM. Results of a phase 3 trial showed that the panobinostat-containing regimen improved the overall response rate and progression-free survival...

Chronic heart failure is a common and complex clinical syndrome that results from impaired cardiac relaxation or contraction. There have been considerable advances in the management of chronic heart failure; however, the mortality rate remains high. Patients with chronic heart failure may experience multiple debilitating symptoms, such as fatigue, pain, and peripheral oedema. However, breathlessness may be considered the most debilitating symptom. The management of chronic heart failure aims to improve the patient's quality of life by reducing symptoms and supporting the patient to manage their condition...

Fatigue is a common "ghost" symptom in patients with multiple sclerosis (MS), an autoimmune disease mediated by T cells that target myelin antigens of the central nervous system. As fatigue has been associated with inflammatory states, its occurrence may negatively impact MS progression. The aim of this study was to evaluate the impact of fatigue on the cytokine profile of patients with relapsing-remitting (RR) MS. For our study, blood were collected from MS patients in clinical remission phase with (n=15) and without (n=15) fatigue...

PURPOSE: We profiled the etiology and recovery of neuromuscular fatigue post-simulated-soccer-match-play. METHODS: Fifteen semi-professional players completed a 90 min simulated soccer match. Pre-, immediately-post and at 24, 48 and 72 h participants completed a battery of neuromuscular, physical and perceptual tests. Perceived fatigue and muscle soreness were assessed via visual analogue scales. Maximum voluntary contraction (MVC) and twitch responses to electrical (femoral nerve) and magnetic (motor cortex) stimulation during isometric knee-extensor contractions and at rest were measured to assess central (voluntary activation, VA) and peripheral (quadriceps potentiated twitch force, Qtw,pot) fatigue, and responses to single and paired-magnetic stimuli were assessed to quantify corticospinal excitability and short-intracortical inhibition (SICI), respectively...

In acute leukemia, leukemic infiltration of the breast is extremely rare. We report a case of biphenotypic acute leukemia (BAL) that presented as a breast mass. A 30-year-old woman presented with a 4-month history of a right breast mass with nipple discharge and easy fatigue. She had received chemotherapy and peripheral blood stem cell transplantation for BAL and had been in complete remission for the last 2 years. Core needle biopsy of the breast mass revealed monomorphous infiltrates of blast cells with round nuclei and fine chromatin, consistent with leukemic infiltration...

PURPOSE: Activin receptor-like kinase 1 (ALK1) is a novel target in angiogenesis. Concurrent targeting of ALK1 and vascular endothelial growth factor (VEGF) signaling results in augmented inhibition of tumor growth in renal cell carcinoma (RCC) xenograft models. Dalantercept is an ALK1 receptor-fusion protein that acts as a ligand trap for bone morphogenetic proteins (BMP) 9 and 10. The DART Study evaluated the safety, tolerability, pharmacokinetics, pharmacodynamics, and antitumor activity of dalantercept plus axitinib in patients with advanced RCC and determined the optimal dose for further testing...

During health, animal sleep is regulated by an internal clock and by the duration of prior wakefulness. During sickness, sleep is regulated by cytokines released from either peripheral cells or from cells within the nervous system. These cytokines regulate central nervous system neurons to induce sleep. Recent research in the invertebrates Caenorhabditis elegans and Drosophila melanogaster has led to new insights into the mechanism of sleep during sickness. Sickness is triggered by exposure to environments such as infection, heat, or ultraviolet light irradiation, all of which cause cellular stress...

Myalgic encephalopathy/chronic fatigue syndrome (ME/CFS) is a debilitating disease of unknown etiology, with hallmark symptoms including postexertional malaise and poor recovery. Metabolic dysfunction is a plausible contributing factor. We hypothesized that changes in serum amino acids may disclose specific defects in energy metabolism in ME/CFS. Analysis in 200 ME/CFS patients and 102 healthy individuals showed a specific reduction of amino acids that fuel oxidative metabolism via the TCA cycle, mainly in female ME/CFS patients...

Guillain-Barré syndrome (GBS) is an autoimmune disease with progressive flaccid paralysis of the extremities. Several auto-antibodies have been identified, binding to myelin, gangliosides, astrocytes or proteins at the nodes of Ranvier. Some epitopes are not confined to the peripheral nerve, suggesting that auto-antibodies may also contribute to symptoms of the central nervous system, which are common in GBS and include anxiety, depression, hallucinations, oneiroid psychosis or fatigue. This notion is supported by treating patients with plasma exchange, resulting in improvement of both central and peripheral symptoms...
