In some countries, adrenaline is available only in glass ampoules. However, simplification of cardiopulmonary resuscitation (CPR) by introducing prefilled syringes may ensure more efficient CPR. The aim of this study was to investigate the impact of different forms of adrenaline on the CPR quality. ⋯ Prefilled syringes with crucial drugs during CPR may significantly improve the quality of CPR performed by two-person teams.

Management of cardiovascular comorbidities in chronic obstructive pulmonary disease patients.
Chronic obstructive pulmonary disease (COPD) is а highly prevalent, complex and heterogeneous clinical condition which is associated with significant concomitant diseases. COPD and cardiovascular diseases (CVDs) often coexist due to the high prevalence of each of these pathological conditions separately as well as the common risk factors (particularly smoking), mechanisms of interaction and influence of systemic inflammation. In addition, decreased pulmonary function in COPD is closely associated with an increased risk of congestive CVDs. ⋯ A large proportion of patients with mild and moderate COPD die due to CVD, which is much more likely than deaths in the same group due to respiratory insufficiency. COPD patients have a higher rate of hospitalization and death, the cause of which are coronary heart disease (CHD), stroke and CHF. Treatment of COPD today is mainly determined by national and international clinical guidelines, which should pay more attention to the problems of the treatment of COPD patients with comorbid conditions.

Poor pressurized metered dose inhaler (pMDI) technique is prevalent, which will diminish treatment gains. In a two-visit study, two novel pMDI training devices with feedback mechanisms; Trainhaler (THR) and Flo-Tone CR (FTCR), were evaluated alongside the traditional verbal inhaler training (VT) in asthma outpatients. ⋯ VT improves the overall pMDI technique, however patients gradually forget their VT. The THR and FTCR devices are retained by the patients as their self-monitoring, all-time personal trainers that boost and maintain their VT between routine clinic visits.

The 3-minute constant-rate stair stepping (3-min CRSST) and constant-speed shuttle tests (3-min CSST) were developed to assess breathlessness in response to a standardized exercise stimulus. Estimating the rate of oxygen consumption (V'O2) during these tests would assist clinicians to relate the stepping/shuttle speeds that elicit breathlessness to daily physical activities with a similar metabolic demand. This study: (I) developed equations to estimate the V'O2 of these tests in people with chronic obstructive pulmonary disease (COPD); and (II) compared the newly developed and American College of Sports Medicine (ACSM) metabolic equations for estimating the V'O2 of these tests. ⋯ This study presents metabolic equations to predict V'O2 of the 3-min CRSST and 3-min CSST for people with COPD that are more accurate than the ACSM metabolic equations.

Malignant pleural effusion (MPE) is associated with a median survival of 3-6 months and causes significant symptoms affecting the overall quality of life in patients with advanced malignancies. Despite the high incidence of recurrent MPE, less than 25% of patients undergo a definitive pleural intervention as recommended by guidelines. In this review, we summarize the latest guidelines for management of MPE by various societies and discuss a multimodal approach in these patients using thoracoscopy with pleurodesis using talc insufflation and placement of tunneled indwelling pleural catheters (TIPC). We also address the role of diagnostic thoracoscopy for histologic and molecular diagnosis and outline our approach to patients with known or suspected MPE.
