BACKGROUND: The current functional guidelines recommend the shuttle walk test (SWT) as an initial screening tool to identify candidates for lung resection without requiring cardiopulmonary exercise testing. This study aims to: (I) assess the use of the SWT in predicting postoperative cardiopulmonary complications; and (II) determine whether the recommended 400 m cut-off is an appropriate distance. METHODS: We retrospectively analysed 101 patients that had performed a SWT prior to surgery...

PURPOSE: Decompression sickness (DCS) is a poorly understood and complex systemic disease caused by inadequate desaturation following a reduction of ambient pressure. A previous proteomic study of ours showed that DCS occurrence but not diving was associated with changes in the plasma proteome in rats, including a dramatic decrease of abundance of the tetrameric form of Transthyretin (TTR). The present study aims to assess the impact on the human blood proteome of a dive inducing significant decompression stress but without inducing DCS symptoms...

Obstructive sleep apnoea (OSA) is associated with increased risk of cardiovascular and cerebrovascular disease, a consequence attributed in part to chronic intermittent hypoxia (IH) resulting from repetitive apnoeas during sleep. Although findings from experimental animal, and human, models have shown that IH is detrimental to vascular regulation, the severity of IH used in many of these animal studies (e.g. inspired fraction of oxygen (FI O2 ) = 2-3%; oxygen desaturation index (ODI) = 120 events h(-1) ) is considerably greater than that observed in the majority of patients with OSA...

Pulse oximetry is an essential monitor for safe anaesthesia but is often not available in low-income countries. The aim of this study was to determine whether the introduction of pulse oximetry with training was feasible and could reduce the incidence of oxygen desaturation during anaesthesia in a low-income country. Pulse oximeters were donated, with training, to 83 non-physician anaesthetists in Malawi. Knowledge was tested immediately before and after training and at follow-up. Providers were asked to record the lowest peripheral oxygen saturation (SpO2 ) for the first 100 cases anaesthetised after training...

OBJECTIVE: Obstructive Sleep Apnea (OSA) has been associated with both subclinical and accelerated atherosclerosis; however, it still remains unknown whether this association is unique or is mediated by the higher burden of co-existing cardio-metabolic disorders frequently seen in patients with OSA. PATIENTS AND METHODS: A total of 40 subjects without clinically diagnosed cardiovascular disease (CVD) referred for polysomnography test were included in the study. Subjects with apnea/hypopnea index (AHI > 15/h) were classified as moderate/severe OSA...

BACKGROUND: Lymphangioleiomyomatosis (LAM) is included within group 5 of the current PH classification (unclear multifactorial mechanisms). However, data regarding the occurrence of PH in LAM are scarce. The aims of the study were to describe the prevalence and characteristics of PH in a large cohort of LAM patients with different levels of severity, and to evaluate the role of echocardiography and carbon monoxide diffusion capacity (DLCO) as screening methods for PH in LAM. METHODS: One hundred five LAM patients underwent transthoracic echocardiography, pulmonary function tests (PFTs) and 6-min walk test (6MWT)...

INTRODUCTION: Sleep apnea syndrome (SAS) is an established cardiovascular risk factor in the general population related to inflammation and oxidative stress and is very common among hemodialysis patients. Cardiovascular disease and its complications is the main cause of death among hemodialysis patients. The aim of the present study was to investigate the role of SAS in the promotion of inflammation and oxidative stress and thus in the augmentation of cardiovascular risk in hemodialysis patients...

OBJECTIVES: Hip arthroscopy utilization has significantly increased in recent years. While it is a relatively safe procedure, it is not without risk. Life-threatening complications, albeit rare, can potentially occur and must be appropriately recognized and treated. We describe 2 cases in which patients' undergoing hip arthroscopy developed pulmonary edema and their respective courses of treatment. METHODS: Both patients were being treated for symptomatic femoroacetabular impingement (FAI), with labral tears, requiring operative management after a failed trial of conservative management...

BACKGROUND: Blood-injection-injury (B-I-I) phobia is capable of producing inaccurate hypoxic challenge testing results due to anxiety-induced hyperventilation. CASE REPORT: A 69-yr-old woman with a history of hypersensitivity pneumonitis, restrictive spirometry, exercise desaturation requiring supplementary oxygen on mobilizing, reduced DLco, and B-I-I phobia was referred for hypoxic challenge testing (HCT) to assess in-flight oxygen requirements. HCT was performed by breathing a 15% FIo2 gas mixture, simulating the available oxygen in ambient air onboard aircraft pressurized to an equivalent altitude of 8000 ft...

Daytime sleepiness is a common symptom among hypertensive patients. The aim of this study was to determine subjective sleepiness assessed by Epworth Sleepiness Scale (ESS) and to asses sleep architecture in 304 patients with arterial hypertension. All patients underwent a standardized diagnostic overnight, polysomnography. The control group consisted of 67 normotensives. The hypertensive patients had a decreased sleep efficiency, mean and minimum oxygen saturation levels, and increased apnea/hypopnea index and oxygen desaturation index compared with normotensive patients...

Neonatal intubation is one of the most common procedures performed by neonatologists, however, the procedure is extremely difficult, and high risk. Neonates who endure the procedure often experience adverse events, including bradycardia and severe oxygen desaturations. Because of low first attempt success rates, neonates are often subjected to multiple intubation attempts before the endotracheal tube is successfully placed. These factors conspire to make intubation one of the most dangerous procedures in neonatal medicine...

OBJECTIVE: Obstructive sleep apnoea (OSA) is a risk factor for vascular disease and other adverse outcomes. These associations may be at least partly due to early endothelin-1 (ET-1)-mediated endothelial dysfunction (ED). Therefore, we assessed the relationships between subclinical sleep apnoea and plasma levels of ET-1. METHODS: We performed a population-based study among 1255 young and healthy adults aged 25-41 years. Cardiovascular disease, diabetes or a body mass index >35 kg/m(2) were exclusion criteria...

A 52-year-old obese gentleman presented to the hospital with complaints of fever and shortness of breath for 10 days. He was admitted in the ward and treated for acute exacerbation of asthma. He was shifted to the Intensive Care Unit (ICU) for persistent fever, neck swelling, airway obstruction and desaturation. Ludwig's angina was suspected and computed tomography of neck confirmed it. A difficult airway was anticipated and preceded with surgical tracheostomy. The patient had hypersensitivity reactions to piperacillin/tazobactam; hence, he was treated with clindamycin and metronidazole...

OBJECTIVE: Children with Down syndrome (DS) are liable to develop obstructive sleep apnea (OSA) due to many anatomical airway abnormalities. The tonsils and adenoid occupy part of the airway space, and their removal may be helpful in relieving airway obstruction. The aim of this study was to assess the effectiveness of adenotonsillectomy in the treatment of OSA in those children. METHODS: Fifty DS children with difficult breathing were recruited, and they were subjected to polysomnographic examination (PSG)...

BACKGROUND: Non-invasive Neurally Adjusted Ventilator Assist (NIV-NAVA) was introduced to our clinical practice via a pilot and a randomized observational study to assess its safety, feasibility, and short term physiological effects. METHODS: The pilot protocol applied NIV-NAVA to 11 infants on nasal CPAP, high-flow nasal cannula (HFNC), or nasal IMV (NIMV), in multiple 2-4 h periods of NIV-NAVA for comparison. This provided the necessary data to design a randomized, controlled observational cross-over study in 8 additional infants to compare the physiological effects of NIV-NAVA to NIMV during 2-hour steady state conditions...
