A large proportion of empirical research and reviews investigating the ergogenic potential of sodium bicarbonate (NaHCO3) supplementation have focused predominately on performance outcomes and only speculate about underlying mechanisms responsible for any benefit. The aim of this review was to critically evaluate the influence of NaHCO3 supplementation on mechanisms associated with skeletal muscle fatigue as it translates directly to exercise performance. Mechanistic links between skeletal muscle fatigue, proton accumulation (or metabolic acidosis) and NaHCO3 supplementation have been identified to provide a more targeted, evidence-based approach to direct future research, as well as provide practitioners with a contemporary perspective on the potential applications and limitations of this supplement...

BACKGROUND: Discriminating circulatory problems with reduced stroke volume from de-conditioning in which the muscles cannot consume O2 normally by gas exchange parameters is difficult. METHODS: We performed combined stress echo and cardio-pulmonary (CPET) tests in 110 patients (20 normal effort capacity, 54 attenuated stroke volume response, 36 de-conditioning) to evaluate multiple hemodynamic parameters and oxygen content difference (A-VO2 Difference) in four predefined activity levels to assess which of the gas measures may help in the discrimination...

OBJECTIVE: Our asphyxia cardiac arrest (ACA) rat model is well established. The original model was designed in the 1990(th) using halothane and nitrous oxide for pre-insult anesthesia. Because of its hepato-toxicity and its potential to induce severe liver failures, halothane is no longer used in clinical anesthesia for several years. In order to minimize the health risk for our laboratory staff as well as to keep the experimental settings of our model on a clinically oriented basis we decided to replace halothane by sevoflurane...

OBJECTIVE: In asthma patients, the assessment of activity limitation is based on questions evaluating how limited the patient feels in their activities. However, the lack of functional data complicates the interpretation of the answers. We aimed to evaluate the intensity of relationships between the patient's perception of activity limitation and the results of several functional tests. METHODS: Twenty patients complaining of asthma exacerbation were invited to complete three scores (Chronic Respiratory Disease questionnaire, Asthma Control Questionnaire, Hospital Anxiety and Depression scale)...

The use of Cardiopulmonary bypass (CPB) and extracorporeal membrane oxygenator (ECMO) in patients suffering from Sickle cell disease (SCD) needs specific precautions. Whereas, no consensual protocols have been established to clarify therapeutic management. CASE REPORT A 7-year-old boy was admitted to the hospital for surgery of advanced endocarditis.  Major dyspnea, hemodynamic distress and fever were noted on physical examination. Biological tests exploring anaemia revealed Haemoglobin (Hb) S levels of 39...

Pulmonary hypertension (PH) is a cardio-pulmonary disorder that may involve multiple clinical conditions and can complicate the majority of cardiovascular and respiratory diseases. Its definition is an increase in mean pulmonary artery pressure (mPAP) \hbox{$\geqslant $} ⩾ 25 mmHg at rest, leading to right heart failure and ultimately death. The clinical classification of pulmonary hypertension (PH) categorizes PH into groups which share similar pathophysiological and hemodynamic characteristics and treatments...

Aortic dissection is very rare in obstetrics, but it is a fatal disease. A 37-weeks primigravida woman with dyspnea and pitting edema presented to our emergency room. The patient was diagnosed with preeclampsia and underwent an emergency cesarean section under spinal anesthesia. The patient complained of severe dyspnea after the cesarean section, and the chest computed tomography scan was done. With the finding of aortic dissection, cardiopulmonary arrest occurred 5 hours after the cesarean section, and the patient died without reaction to cardio-pulmonary resuscitation...

Objective: To investigate the clinical efficacy and safety of temporary heart pacemaker for emergency treatment of patients with acute and severe cardiovascular diseases. Methods: The clinical data of 147 patients with cardiac arrest or bradyarrhythmia from August 2007 to December 2015, was analyzed retrospectively in Department of internal and Emergency Medicine, People's Hospital of Henan. Based on the rescue methods, all patients were divided into two groups: observation group (80 cases, among whom, 49 cases with cardiac arrest and 31 cases with bradyarrhythmia) and control group (67 cases, among whom 39 cases with cardiac arrest and 28 cases with bradyarrhythmia)...

BACKGROUND: In-flight cardiac arrest (IFCA) is a relatively rare but challenging event. Outcomes and prognostic factors are not entirely understood for victims of IFCAs in commercial aviation. METHODS: This was a retrospective cohort study of airline passengers who experienced IFCA. Demographic and operational variables were studied to identify association in a multivariate logistic regression model with the outcome of survival-to-hospital. In-flight medical emergencies were processed by a ground-based medical center...

While forcing of end-tidal gases by regulating inspired gas concentrations is a common technique for studying cardio-respiratory physiology, independently controlling end-tidal gases is technically challenging. Feedforward control methods are challenging because end-tidal values vary as a dynamic function of both inspired gases and other non-regulated physiological parameters. Conventional feedback control is limited by delays within the lungs and body tissues, and within the end-tidal forcing system itself...

Exertional dyspnoea is among the dominant symptoms in patients with chronic heart failure and progresses relentlessly as the disease advances, leading to reduced ability to function and engage in activities of daily living. Effective management of this disabling symptom awaits a better understanding of its underlying physiology.Cardiovascular factors are believed to play a major role in dyspnoea in heart failure patients. However, despite pharmacological interventions, such as vasodilators or inotropes that improve central haemodynamics, patients with heart failure still complain of exertional dyspnoea...

We describe a middle aged previoulsy healthy female patient who presented with clinical features suggestive of acute heart failure. Investigations revealed very high NT pro-BNP, right heart enlargement, bilateral pulmonary alveolar edema and bilateral pleural effusion. In view of falling platelet counts and exudative pleural effusion inflammatory/infective causes were considered. Her Weil Felix test was strongly positive and IgM for scrub typhus also returned positive. She was started on doxycycline to which there was dramatic improvement...

BACKGROUND: Long-acting bronchodilators, including long-acting beta2-agonists (LABA) and the anticholinergic tiotropium, are recommended as initial maintenance therapy in COPD. Studies to date have been limited in size and reported ambivalent results on the comparative risk of cardiovascular, cerebrovascular and pulmonary adverse events between these two long-acting bronchodilators. Moreover, little information is available for the period when treatment is first initiated, a time when subjects may be especially at risk...
