RESUMO
BACKGROUND: Limited data are available on patients with chronic lung disease (CLD) presenting with acute myocardial infarction (AMI). We aimed to analyse baseline characteristics, treatment and outcome of those patients enrolled in the Swiss nationwide prospective AMIS Plus registry. METHODS: All AMI patients enrolled between January 2002 and December 2021 with data on CLD, as defined in the Charlson Comorbidity Index, were included. The primary endpoints were in-hospital mortality and major adverse cardiac and cerebrovascular events (MACCE), defined as all-cause death, reinfarction and cerebrovascular events. Baseline characteristics, in-hospital treatments and outcomes were analysed using descriptive statistics and logistic regression. RESULTS: Among 53,680 AMI patients enrolled during this time, 5.8% had CLD. Compared with patients without CLD, CLD patients presented more frequently with non-ST-elevation myocardial infarction (MI) and type 2 MI (12.8% vs. 6.5%, p < 0.001). With respect to treatment, CLD patients were less likely to receive P2Y12 inhibitors (p < 0.001) and less likely to undergo percutaneous coronary interventions (68.7% vs. 82.5%; p < 0.001). In-hospital mortality declined in AMI patients with CLD over time (from 12% in 2002 to 7.3% in 2021). Multivariable regression analysis showed that CLD was an independent predictor for MACCE (adjusted OR was 1.28 [95% CI 1.07-1.52], p = 0.006). CONCLUSION: Patients with CLD and AMI were less likely to receive evidence-based pharmacologic treatments, coronary revascularization and had a higher incidence of MACCE during their hospital stay compared to those without CLD. Over 20 years, in-hospital mortality was significantly reduced in AMI patients, especially in those with CLD.

PURPOSE: Hypertension should be confirmed with the use of home BP measurement (HBPM) or 24h ambulatory BP measurement (ABPM). The aim of our study was to compare measurements obtained by OBPM, HBPM and ABPM in individuals with elevated OBPM participating in the population-based Swiss Longitudinal Cohort Study (SWICOS). MATERIAL AND METHODS: Participants with OBPM ≥140/90 mmHg assessed their BP using HBPM and ABPM. The cut-off for hypertension was ≥135/85 mmHg for HBPM, ≥130/80 mmHg for ABPM. White-coat hypertension (WCH) was defined as normal HPBM and ABPM in participants not taking antihypertensive drugs. Uncontrolled hypertension was defined as hypertension in HBPM or ABPM despite antihypertensive treatment. RESULTS: Of 72 hypertensive subjects with office BP ≥140/90 mmHg and valid measurements of HBPM and ABPM, 39 were males (aged 62.8 ± 11.8y), 33 were females (aged 57.4 ± 14.2y). Hypertension was confirmed with HBPM and ABPM in 17 participants (24%), with ABPM only in 24 further participants (33%), and with HBPM only in 2 further participants (3%). Participants who had hypertension according to ABPM but not HBPM were younger (59 ± 11 y versus 67 ± 16 y; p < 0.001) and more frequently still working (83% versus 23%; p < 0.001). The prevalence of WCH was 28%. Among the 32 subjects taking antihypertensive drugs, uncontrolled hypertension was found in 49%. CONCLUSION: This population-based study found a high prevalence of WCH and potential uncontrolled hypertension among individuals with elevated OBPM. This study, therefore, supports the ESH recommendations of complementing OBPM by ABPM or HBPM. The use of HBPM instead of ABPM for the confirmation of hypertension in individuals with elevated OBPM might lead to underdiagnosis and uncontrolled hypertension, in particular in the younger working population. In these individuals, this study suggests using ABPM instead of HBPM.
What is already known?Comparing blood pressure measurements in the doctor's office or clinic (OBPM) with out-of-office measurements (either self-measurement at home (HBPM) or ambulatory over 24 hours during both day and night times (ABPM)) improves the accuracy of hypertension diagnosis.Why was the study done?This study was done to provide additional information by comparing HBPM and ABPM in individuals with elevated OPBMs (≥140/≥90mmHg), who participated in the Swiss Longitudinal Cohort Study (SWICOS)What was found?Our study confirmed differences between office and out-of-office measurements. In 60% of the study participants, ABPM or HBPM confirmed the elevated OBPM but only around half of these participants were treated with antihypertensive drugs. A high proportion of the participants (28%) had white coat hypertension.What does this study add?Our study adds to the literature already available on this issue by reporting on data obtained from a cohort of individuals living in a countryside area of Southern Switzerland.This study also showed that HBPM might underestimate BP in the younger working population.How might this impact on clinical practice?The findings of this population-based study support the European Society of Hypertension recommendations for wider use of out-of-office blood pressure measurement for the confirmation of hypertension in individuals with elevated OBPM to avoid underdiagnosis and uncontrolled hypertension.In the young working population, ABPM should be used instead of only HBPM to confirm hypertension.

OBJECTIVE: Lung cancer (LC) is one of the most frequently diagnosed cancers and the leading cause of cancer mortality worldwide. The aim of this study was to get a comprehensive insight into the epidemiology of LC among patients in Vojvodina, the Northern Serbian region, during the ten-year period. PATIENTS AND METHODS: This retrospective study was performed using LC hospital registry data of the Institute for Pulmonary Diseases of Vojvodina (IPBV) from 2011 to 2020. All patients reported in the registry with a place of residence in Vojvodina were included in this study. The data used in this research were: date of diagnosis, gender, age at diagnosis, place of residence, smoking habits at diagnosis, the intensity of smoking (pack/years), ECOG performance (0-5), histological cancer type, TNM classification and disease stage. RESULTS: A total of 12,055 LC patients were included, 69.6% of whom were male. The percentage of female LC patients significantly increased, from 26.9% in 2011 to 35.9% in 2020 (p<0.001). Non-small cell lung cancer (NSCLC) was diagnosed in 80.8% of patients, while 15.4% of patients had small cell lung cancer (SCLC). The most common histological type was adenocarcinoma (41.9%), followed by squamous cell carcinoma (30.0%) and SCLC (15.4%). CONCLUSIONS: The number of diagnosed LC patients in the Northern Serbian region increased over the past decade and is significantly higher in females. There was a strong correlation between smoking habits and LC in both genders. Our results also indicate the importance of introducing and promoting LC screening programs for all risk populations, particularly current and ex-smokers of younger age.

OBJECTIVE: Laryngoscopy and endotracheal intubation (EI) often provoke a marked sympathetic response, which leads to tachycardia and hypertension. The aim of this study was to investigate the effect of different doses of remifentanil on the cardiovascular response to laryngoscopy and EI. PATIENTS AND METHODS: 100 patients were included in this randomized study. The participants were divided into four groups of 25 patients each. The patients in the control group did not receive remifentanil. The patients from other three groups received remifentanil prior to induction of anesthesia at doses of 0.5 µg/kg, 1 µg/kg, and 1.5 µg/kg. Hemodynamic parameters were measured before and after administration of remifentanil, after induction of anesthesia and one minute after EI. RESULTS: After administration of remifentanil and induction of anesthesia, a decrease in arterial pressure and heart rate occurred in most patients. After EI, an increase in arterial pressure and heart rate was observed in most patients. The largest increase was recorded in the group of patients who did not receive remifentanil. The best hemodynamic response was observed in patients who received 1 and 1.5 µg/kg of remifentanil. CONCLUSIONS: Remifentanil at the doses of 1-1.5 µg/kg is absolutely safe for co-induction of anesthesia with thiopental. Such dosing regimen provides optimal conditions for reducing hemodynamic response to laryngoscopy and EI.

Objective: It is unclear whether Benralizumab effectiveness in severe eosinophilic asthma can be influenced by nasal polyposis (NP) or allergic status associations. We evaluated whether Benralizumab long-term efficacy in asthma outcomes could be different in subjects with atopy (SAEA) compared to the effectiveness in those without allergies (SNAEA) and in individuals with NP compared to those without NP. Methods: This observational retrospective study considered 95 consecutive patients divided into allergic (SAEA; n:65[68.4%]; skin prick tests positive [SPT] and/or IgE values ≥100 UI/mL), and non-allergic (SNAEA; n:30[31.6%], SPT negative and normal IgE levels<100 UI/mL). Overall population was also divided into two groups according to NP presence (NP+:39[41%] and NP-:56[59%]). Benralizumab treatment mean was19.7±7.2 months (range 12-35). Results: No differences in Benralizumab effectiveness were found in asthma outcomes in patients with/without NP. SNOT-22 improvement was higher in NP+ (-22±24) compared to NP- groups (6.33±15.5;p=0.055). FEV1 (16.33±19.22%), ACT(7.45±3.95) increases and frequency of SABA use (3.37±4.99) reduction were higher in SAEA compared to what obtained in non-allergic subjects (FEV1:8.15±15.6%,p=0.043; ACT:4.89±3.57,p=0.005; SABA use:-1.16±1.84;p=0.015). 93.8% of SAEA patients whereas only 72.2% of SNAEA individuals reduced OC doses at least half after Benralizumab (p=0.035). These results were partially confirmed by linear regression models showing associations between allergic status and FEV1, ACT and SABA use changes (ß=8.37;p=0.048, ß=2.056;p=0.033 and ß=-2.184;p=0.042 respectively). Conclusion: Benralizumab effectiveness in asthma appears to be independent of NP presence. The allergic eosinophilic disease, compared to just eosinophilic asthma, may be a more severe phenotype. Benralizumab may have greater efficacy in SAEA on some outcomes.

This article explores current evidence on the role of oxidative stress in viral infections, and on the use of antioxidant drugs as adjunctive treatment. MEDLINE/PubMed was searched for appropriate keywords, and preclinical and clinical studies with reviews were retrieved and examined by authors. Old and current evidence shows that GSH content reduction is the main mechanism of redox imbalance in viral-infected cells. Clinical studies found that GSH levels are depleted in patients with viral infections such as HIV and SARS-CoV. Viral infections activate inflammation through different pathways, and several of these mechanisms are related to oxidative stress. NAC is a precursor of GSH, and many of its intracellular effects are mediated by GSH replenishment, but it also activates some anti-inflammatory mechanisms. NAC has an excellent safety profile and better oral and topical bioavailability than GSH. These characteristics make NAC a suitable option as a repurposed drug. Adjunctive antioxidant treatment may improve the outcomes of antiviral therapies. Current evidence supports the rationale for this practice and some clinical experience showed encouraging results.

OBJECTIVE: Long-term efficacy of Benralizumab in real life is not clearly known. We assessed the long-term effectiveness persistence to anti-IL-5R treatment in a group of severe eosinophilic asthmatics. PATIENTS AND METHODS: We retrospectively analyzed 95 individuals affected by severe asthma (36 males ̶ 37.9%; mean age 58.1 ± 12.2) treated with Benralizumab (mean time 19.7 ± 7.2 months, range 12-35). Outcomes were evaluated at the beginning and at the end of patients' treatment periods. RESULTS: Mean baseline blood eosinophils were 897.5 ± 720.1 cells/µL (11 ± 5.6%) decreasing to 7.4 ± 20.6 cells/µL (0.97 ± 0.26%; p < 0.0001) after Benralizumab. FENO likewise decreased from 63.9 ± 68.4 to 28.4 ± 23.6 ppb, while FEV1% significantly improved (p < 0.0001). Mean FEF25-75 also increased from 45.8 ± 24.6% to 60.7 ± 24.6%, whereas RAW dropped from 202.15 ± 109.6% to 135.2 ± 54.75% (p < 0.0001). Also, lung volumes greatly decreased. ACT/ACQ significantly improved, while exacerbations number fell from 4.1 ± 2.4, before anti-IL-5R, to 0.33 ± 0.77, after treatment (p < 0.0001). Rhinitis severity levels and SNOT-22 also changed favorably. Patients that took long-term OCs were 71.6% before treatment, decreasing to 23.2% after Benralizumab (p < 0.0001), with an OCs dose reduction from 14.8 ± 8.9 to 1.45 ± 2.8 mg/day (p < 0.0001). 51.6% of subjects used SABA as needed before Benralizumab, falling to 4.2% after treatment. Several patients showed a reduction of ICS doses, SABA use and maintenance therapy step-down. Clinical/biological response with anti-IL-5R remained constant or even improved in terms of exacerbations or maintenance therapy reductions over time. On the contrary, FEF25-75% improvement slowed down in the long-term. No relationship was found between baseline blood eosinophil number and therapeutic response. CONCLUSIONS: Long-term Benralizumab effectiveness persistence in all outcomes in real life was confirmed.

The aim of our research was to evaluate the changes in levels of cytokines and redox state parameters in blood and isolated heart of rats subjected to different swimming protocols. Rats were divided into 3 groups: 1) controls, 2) moderately trained rats that during all 12 weeks swam 1 h/day, 5 days/week, and 3) overtrained rats that in 10(th) week swam twice, 11(th) week 3 times, and in 12(th) week 4 times a day for 1 h. After sacrificing, blood from jugular vein was collected, and the heart excised and perfused on a Langendorff apparatus. Samples of the coronary effluent were collected during coronary autoregulation. Levels of superoxide anion radical (O(2)(-)), hydrogen peroxide (H(2)O(2)), nitric oxide (NO) and thiobarbituric acid reactive substances (TBARS) were measured in plasma and coronary effluent, while reduced glutathione (GSH), activities of superoxide dismutase (SOD) and catalase (CAT) were measured in erythrocytes. Venous blood was also used for interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-alpha) determination. Moderate training protocol induced the decrease of TBARS in plasma, while both training protocols induced the decrease of O(2)(-) and H(2)O(2) in coronary effluent. There was no significant difference in levels of cytokines between groups. The results of study add evidence about beneficial effects of moderate-intensity training on blood and cardiac redox state of rats, and furthermore, shows that exercising frequently, if the intensity stays within moderate range, may not have detrimental effects.

Nodal mediastinal staging is a crucial part of the diagnostic workup of patients with nonsmall- cell lung cancer (NSCLC) for planning optimal treatment. Transesophageal endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) and real-time endobronchial ultrasounds transbronchial needle aspiration (EBUS-TBNA) are accurate, minimally invasive and safe diagnostic techniques for mediastinal staging. Because of the different accessibility to the mediastinum, they are considered complementary and their combination increases the diagnostic yield as compared with the either alone. Recent studies have shown that endosonography represents the best initial test for invasive mediastinal evaluation in NSCLC. Endoscopic ultrasound (with bronchoscope)-guided fine needle aspiration (EUS-B-FNA) is a recently introduced procedure consisting of a transesophageal needle aspiration using an ultrasound bronchoscope. It allows to perform both transbronchial and transesophageal needle sampling with the same instrument, in the same session and by one operator only, thus maximizing time and costs savings. In a recent study Oki et al. randomized 110 patients with hilar/mediastinal adenopathies or lung abnormalities adjoining both the esophagus and the bronchi, to undergo EBUSTBNA or EUS-FNA performed by pulmonologists with an echobronchoscope. The Authors demonstrated that both procedures provide a high diagnostic yield, without any difference in the number of adverse events and a good comparable tolerance. Nevertheless, the transesophageal approach guaranteed a significantly lower dose of anesthetics and sedatives, a shorter procedural time, fewer oxygen desaturations, a significantly lower cough score and a higher operator satisfaction. In this review our aim was to discuss the findings by Oki et al. in the context of medical literature, highlighting the importance of the EUS-B needle aspiration technique in diagnosing mediastinal and lung lesions, when EBUS-TBNA is deemed less suitable. Finally, we pointed out the importance of interventional pulmonologists being trained to perform mediastinal sampling by the esophageal route, to choose the best solution in every technical and clinical occurence.
RESUMO
Long-acting ß2-adrenoceptor agonists, formoterol and salmeterol, represent a milestone in the treatments of chronic obstructive lung diseases. Although no specific indications concerning the choice of one molecule rather than another are provided by asthma and COPD guidelines, they present different pharmacological properties resulting in distinct clinical employment possibilities. In particular, salmeterol has a low intrinsic efficacy working as a partial receptor agonist, while formoterol is a full agonist with high intrinsic efficacy. From a clinical perspective, in the presence of low ß2-adrenoceptors availability, like in inflamed airways, a full agonist can maintain its bronchodilatory and non-smooth muscle activities while a partial agonist may be less effective. Furthermore, formoterol presents a faster onset of action than salmeterol. This phenomenon, combined with the molecule safety profile, leads to a prompt amelioration of the symptoms, and allows using this drug in asthma as an "as needed" treatment in patients already on regular treatment. The fast onset of action and the full agonism of formoterol need to be considered in order to select the best pharmacological treatment of asthma and COPD.

Sarcoidosis is a benign disease of unknown etiology that is characterized by the formation of noncaseating epithelioid cell granulomas. Although a multisystemic disease, it primarily affects the lung and the lymphatic system of the body. When a histological diagnosis is required, bronchoscopy is frequently employed because allows tissue sampling from several anatomic sources, such as airways, lung parenchyma and hilar/mediastinal nodes. Transbronchial lung biopsies (TBLB), endobronchial biopsies (EBB) and conventional transbronchial needle aspiration (cTBNA) have long been the only bronchoscopic techniques to diagnose sarcoid granulomas, until the advent of endobronchial ultrasound guided needle aspiration (EBUS-TBNA). This technique shows excellent yield in sampling mediastinal adenopathies with a higher sensitivity than the conventional technique in sarcoidosis as well. Furthermore, non controlled studies, demonstrated its diagnostic superiority than EBB and TBLB in stages I (hilar adenopathies only) and II (hilar lymph nodes and parenchymal infiltrations) thoracic sarcoidosis. In a recent study, Gupta et al., randomized 130 patients with suspected stage I and II disease to undergo EBUS-TBNA or cTBNA in conjunction with transbronchial and endobronchial biopsies. The Authors demonstrated that the yield of cTBNA added to EBB and TBLB is similar to EBUS-TBNA plus transbronchial biopsies, although ultrasound guided transbronchial needle aspiration shows the best single diagnostic efficacy. In this review article we aimed to discuss the findings by Gupta in the context of medical literature, highlighting the importance of adding nodal aspirations (with or without ultrasound guidance) with bronchial and transbronchial samples to gain the optimal sensitivity in obtaining histological confirmation. We finally pointed out the need for future studies to evaluate the potential role of rapid on-site evaluation (ROSE) of needle aspirates in reducing additional sampling and related costs and complications.

PURPOSE: The present study was designed to investigate whether there is a difference in the anastomotic leakage rate (AL) between the single stapling (CSA) and double stapling (DSA) anastomosis techniques. METHODS: One hundred consecutive rectal cancer patients who underwent rectal resection with primary anastomosis were enrolled in this study. RESULTS: The overall rate of clinical anastomotic leakage in both groups was 7 % (7/100); 6 % (3/50) in the CSA group and 8 % (4/50) in the DSA group. The anastomotic technique did not have any significant influence on the rate of AL. All AL were seen in low anastomoses (7 cm and below). The rate of AL in patients with a diverting stoma (13 %, 3/23) was not significantly different from that of the patients without (5.2 %, 4/77) (p = 0.195). The mean length of the operation was significantly shorter in the DSA group compared to the CSA group, at 127 and 141 min, respectively (p = 0.005). There were significantly higher rates of AL in patients receiving preoperative long course radiotherapy (15.4 %, 6/39) compared with those who did not receive radiotherapy (1.63 %, 1/61) (p = 0.014). CONCLUSIONS: The CSA and DSA techniques are equally safe for the creation of a rectal anastomosis, without any significant difference in the AL rate. However, we recommend using the DSA technique because it has other definite advantages. In cases of neoadjuvant treatment and a low anastomosis, proximal diversion is recommended.

The morbidity and mortality rates attributed to smoking are substantial and cigarette smoke remains the first preventable cause of premature death worldwide. Despite the knowledge of the adverse consequences of smoking, many smokers struggle to quit. Cigarette smoking is the primary cause of chronic obstructive pulmonary disease, and smoking cessation represents the most effective way of stopping its progression. Varenicline is one of the first-line smoking cessation aids recommended in many Clinical Practice Guidelines and its efficacy and safety have been demonstrated in several clinical trials. Varenicline has a unique mechanism of action and clinical trials support its use as an effective and generally well-tolerated therapy. This article reviews the clinical pharmacological trials on smoking cessation published in recent years on varenicline, with particular attention to the outcomes used in the studies. MedLine, the Cochrane database and Embase were evaluated. Almost all the trials have, as a primary endpoint, the abstinence from cigarettes at 9-12 weeks of treatment. Only one study considers lung function spirometric changes as a secondary endpoint. No study has evaluated lung function. This marker could be very important as a way of evaluating, objectively, an improvement in lung function, which correlates also with subjective parameters, as dyspnea and fatigue.

PURPOSE: The prediction of outcome for patients with gastric cancer is determined largely by the presence of lymph node metastases, which could be detected by sentinel lymph node (SLN) biopsy (SLNB). The purpose of this work was to determine the feasibility of SLNB in patients with gastric cancer for the assessment of regional lymph node status, including performing immunohistochemical (IHC) staining of SLN tissue. METHODS: We reviewed 137 consecutive patients with operable gastric cancer over a 10-year period using a retrospective (to examine skip metastases) and prospective (to evaluate successful mapping) study design. SLNs were mapped, biopsied and subsequently explored by routine hematoxylin & eosin (H&E) staining and by IHC staining using a cytokeratin 8/18 antibody. RESULTS: The retrospective study showed a low incidence of skip metastases (3.7%). Mapping of SLNs in the prospective study was highly successful (98.2%). During the prospective study, IHC examination of SLNs from 56 patients showed statistically significant change in disease stage. CONCLUSION: This study demonstrated highly successful mapping and biopsy of SLNs (98.2%), as well as highest specificity (100%), sensitivity (100%) and accuracy (100%) to predict metastasis in the surrounding lymph nodes of gastric carcinoma. In addition, we believe that IHC study might enable "ultra staging" and additional selection of patients for further cancer treatment.

INTRODUCTION: Mammary sarcomas are relatively uncommon and they represent less than one percent of all primary breast malignancies. Osteosarcoma of the breast, unassociated with other tumors, is distinctly rare, with published references generally limited to case reports and occasional cases in several series encompassing a heterogeneous group of mammary sarcomas and extraosseous osteosarcomas at various sites. The authors present a patient with pure osteosarcoma of the breast, osteoblastic type, with biologically aggressive pattern. CASE REPORT: A 79-year-old lady became aware of a rapidly enlarging lump in the lateral part of the right breast. Clinical examination revealed a firm to hard, mobile, irregular, and painful breast lump measuring about six by four cm. On examination there was no axillary or supraclavicular lymphadenopathy. After initial diagnosis, excisional biopsy without dissection of the axillary lymph nodes was performed. Therefore, the histological and immunohistochemical findings established the diagnosis of pure primary osteosarcoma of the breast. CONCLUSION: Pure osteosarcoma of the breast is extremely rare and needs to be distinguished from a variety of benign and malignant breast lesions producing metaplastic bone. Less than a hundred cases of pure osteosarcoma of the breast were reported, but diagnostic confirmation with immunohistochemistry has been performed in relatively few of these cases.

AIM: The prevalence of respiratory diseases has been assessed in community based epidemiological studies. General practice is the ideal position to intercept chronic respiratory illness and manage the first level of follow up as well. Aim of this study was to obtain General Practitioners (GPs) data about management and clinical setting of patients with respiratory diseases. METHODS: This is a prospective observational study; 272 Italian GPs were involved and equally distributed on the Italian territory. The interviews were performed by means of a questionnaire consisting in which consisted of 25 questions regarding individual demographics, catchment area, professional behavior, health attitudes. RESULTS: Each GP reported that about 13% of the pooled patients had a respiratory disease. Concerning as for chronic respiratory illnesses, spirometry was frequently prescribed and in these patients 63% of the interviewed GPs thought that the lung functional test was fundamental. GPs also reported the importance of improving health education, well aware of its importance in the prevention of respiratory diseases; and furthermore in improving the current health system organization. As for with regard to cigarette smoke, interviewed GPs reported that the 26% of their assisted subjects were smokers and the commitment to discouraging the smoking habit was very high. CONCLUSION: This is a large National survey that involved GPs and real life data about management of patients with respiratory diseases. The role of GPs in the management of chronic respiratory patients represents an important tool valuable in increasing primary care identification, education and treatment of respiratory diseases.

Anaesthesia awareness (AA) is postoperative recall of events experienced under general anaesthesia. Most frequently patients remember an auditory perception, the feeling of motor function lost, pain, helplessness, anxiety, panic, impending death. The prevalence of awareness in nonobstetric and noncardiac surgical cases is 0.1%-0.2%. The prevalence is higher in cardiac surgery, obstetric and major trauma cases. According to the results of many studies light anaesthesia is the most common cause of the AA. Posttraumatic stress disorder appears in 33%-56% of patients who experienced awareness during general anaesthesia. Extreme awareness experiences are very uncommon, but traumatic and can have lasting effects on patients. Several brain-function monitors based on the processed electroencephalogram or evoked potentials have been developed to assess anaesthetic depth. Measures to prevent awareness include avoidance of light anesthesia, gaining more knowledge about patient anaesthetic requirements and development of methods to detect consciousness during anesthesia.

The purpose of this study was to investigate the influence of additional resistance training on cardiorespiratory endurance in young (15.8 ± 0.8 yrs) male basketball players. Experimental group subjects (n=23) trained twice per week for 12 weeks using a variety of general free-weight and machine exercises designed for strength acquisition, beside ongoing regular basketball training program. Control group subject (n=23) participated only in basketball training program. Oxygen uptake (VO(2max)) and related gas exchange measures were determined continuously during maximal exercise test using an automated cardiopulmonary exercise system. Muscle power of the extensors and flexors was measured by a specific computerized tensiometer. Results from the experimental group (VO(2max) 51.6 ± 5.7 ml.min(-1).kg(-1) pre vs. 50.9 ± 5.4 ml.min(-1).kg(-1) post resistance training) showed no change (p>0.05) in cardiorespiratory endurance, while muscle strength and power of main muscle groups increased significantly. These data demonstrate no negative cardiorespiratory performance effects on adding resistance training to ongoing regular training program in young athletes.
