Heart failure with reduced ejection fraction (HF) and chronic obstructive pulmonary disease (COPD) frequently coexist, particularly in the elderly. Given their rising prevalence and the contemporary trend to longer life expectancy, overlapping HF-COPD will become a major cause of morbidity and mortality in the next decade. Areas covered: Drawing on current clinical and physiological constructs, the consequences of negative cardiopulmonary interactions on the interpretation of pulmonary function and cardiopulmonary exercise tests in HF-COPD are discussed...

Discharging neonates in a proper car safety seat is standard of care in the United States and many other countries. However, not every neonate can be safely positioned in a standard semi-upright car seat. In these cases, providers may opt for a travel device that allows the infant to lie flat, either supine or prone, known as a car bed. Minimal evidence exists to guide providers on car bed safety and help determine which infants would benefit from discharge in a car bed. In this article, we provide a comprehensive summary of existing literature on the safety of car beds for motor vehicle travel, car bed use in specific patient populations, and car beds vs...

BACKGROUND: Venovenous extracorporeal membrane oxygenation (vv-ECMO) is an effective treatment for severe respiratory failure. The interaction between the cardiorespiratory system and the oxygenator can be explored with mathematical models. Understanding the physiology will help the clinician optimise therapy. As others have examined O2 exchange, the main focus of this study was on CO2 exchange. METHODS: A model of the cardiorespiratory system during vv-ECMO was developed, incorporating O2 , CO2 and N2 exchange in both the lung and the oxygenator...

Objective: Generalized tonic-clonic seizures are accompanied by cardiovascular and respiratory sequelae that threaten survival. The frequency of these seizures is a major risk factor for sudden unexpected death in epilepsy (SUDEP), a leading cause of untimely death in epilepsy. The circumstances accompanying such fatal events suggest a cardiovascular or respiratory failure induced by unknown neural processes rather than an inherent cardiac or lung deficiency. Certain cortical regions, especially the insular, cingulate, and orbitofrontal cortices, are key structures that integrate sensory input and influence diencephalic and brainstem regions regulating blood pressure, cardiac rhythm, and respiration; output from those cortical regions compromised by epilepsy-associated injury may lead to cardiorespiratory dysregulation...

Objectives: Cardiovascular diseaseand heart failure (CHF) are leading causes of death in systemic lupus erythematosus (SLE). The underlying mechanisms for increased CHF in SLE are unclear but myocardial inflammation and lupus myocarditis (LM) may play a role. We propose that 18 F-fluorodeoxyglucose-positron emission tomography (18 F-FDG-PET)/CT can help diagnose LM. Methods: This report describes eight patients with presumed LM; five patients were evaluated due to active cardiorespiratory symptoms and three patients were participating in a pilot study to determine the prevalence of subclinical myocarditis in SLE...

We report an unusual case of an adult patient carrying a germline PHOX2B frameshift mutation and hence was diagnosed with congenital central hypoventilation syndrome. He came to medical attention after the mutation was identified in his daughter who presented with hypoventilation and a neuroblastoma. Although PHOX2B mutations are usually associated with a phenotype of congenital hypoventilation, severe autonomic dysfunction and neural crest tumors, our patient had no complaints at the time of presentation. At polysomnography we found severe positional hypercapnic central sleep apnea, partly responsive to positional therapy...

Scorpionism is the clinical picture resulting from the inoculation of scorpion venom. It is considered a major public health problem, especially in countries with low resources and tropical or subtropical climate. Poisoning can be fatal especially in the first hours due to respiratory and / or cardiovascular collapse. The compromise of the central nervous system (CNS) is infrequent but varied and complex, being able to be triggered due to multiple and different neurotoxic properties of the toxin. We report here a severe case of poisoning with cardiovascular and neurological compromise in an endemic region of Argentina...

AIM: Recent studies have suggested that non-high-density lipoprotein cholesterol (non-HDL-C) may be a good marker of coronary heart disease and cardiovascular disease risk. Therefore, we investigated the relationship between cardiorespiratory fitness (CRF) and non-HDL-C. METHODS: We evaluated CRF and the incidence of high level of non-HDL-C in 4,067 Japanese men without dyslipidemia. The participants were given a submaximal exercise test, a medical examination, and questionnaires on their health habits in 1986...

High-intensity functional training (HIFT) is an exercise modality that emphasizes functional, multi-joint movements that can be modified to any fitness level and elicit greater muscle recruitment than more traditional exercise. As a relatively new training modality, HIFT is often compared to high-intensity interval training (HIIT), yet the two are distinct. HIIT exercise is characterized by relatively short bursts of repeated vigorous activity, interspersed by periods of rest or low-intensity exercise for recovery, while HIFT utilizes constantly varied functional exercises and various activity durations that may or may not incorporate rest...

In 2017, an autologous chimeric antigen receptor (CAR) T cell therapy indicated for children and young adults with relapsed and/or refractory CD19+ acute lymphoblastic leukaemia became the first gene therapy to be approved in the USA. This innovative form of cellular immunotherapy has been associated with remarkable response rates but is also associated with unique and often severe toxicities, which can lead to rapid cardiorespiratory and/or neurological deterioration. Multidisciplinary medical vigilance and the requisite health-care infrastructure are imperative to ensuring optimal patient outcomes, especially as these therapies transition from research protocols to standard care...
