Abstract
BACKGROUND Blastocystis sp. is a common intestinal protozoan found worldwide. Based on gene analysis, 17 subtypes (STs, ST1-ST17) have been identified, 9 of which have been isolated from humans. Differences in clinical consequences may depend on differences among the STs. Here, we evaluated the prevalence of Blastocystis sp. in patients with colorectal cancer (CRC) compared to a control group and assessed the relationships between Blastocystis sp. infection and sex; age; and CRC grade, stage, and location. METHODS The study included 107 CRC patients (41 women and 66 men, median age 65 years); 124 subjects without colorectal cancer or a history of oncological disease comprised the control group (55 women and 69 men, median age 63). Stool samples were collected from patients before oncological treatment and examined using light microscopy (iodine-stained smear). Additionally, PCR-based identification of Blastocystis sp. was performed in 95 stool samples from CRC patients and 76 stool samples from the control group. RESULTS Light microscopy showed that the prevalence of Blastocystis sp. was significantly higher in CRC patients than in the control group (12.15% and 2.42%, respectively; p = 0.0041). Multivariate analysis showed that the odds of Blastocystis sp. infection were fivefold higher in the CRC group than in the control group. PCR-based molecular examinations demonstrated that the proportion of patients infected with Blastocystis sp. was significantly higher in the CRC group than in the control group (12.63% and 2.63%, respectively; p = 0.023). The predominant ST in the CRC group was ST3, detected in nine patients (75%), followed by ST1 (2 patients, 16.7%) and ST2 (1 patient, 8.3%). No association was found between Blastocystis sp. infection and age, sex, or CRC stage, grade, or location. CONCLUSIONS The results showed that CRC was associated with an increased risk of opportunistic Blastocystis sp. infection, even before oncological treatment. To the best of our knowledge, this is the first report estimating the prevalence of Blastocystis sp. infection in CRC patients before oncological treatment in Europe.

Abstract
Transient or constant impaired immunity is often associated with neoplastic disease or oncological treatment. Among the most common pathogens found in patients with HIV or patients undergoing chemotherapy are protozoans of the Cryptosporidium genus, which cause diarrhea in humans and animals. The present study determined the frequency of Cryptosporidium spp. infections in patients with colorectal cancer (N = 108; 42 women; 66 men; median age, 65 years), before beginning oncological treatment, compared to a control group (N = 125; 56 women, 69 men; median age, 63 years) without colorectal cancer or a history of oncological disease. We also assessed whether Cryptosporidium spp. infections were associated with age, gender, cancer stage (based on Astler-Coller or TNM classification), histological grade, or cancer location. Patients were treated at the Pomeranian Medical University, in 2009-2014. The presence of Cryptosporidium spp. antigen was determined in stool samples, analyzed with a commercial immunoenzymatic test. Cryptosporidium spp. infections occurred significantly more often (p = 0.015) in patients (13%) compared to controls (4%). The patient group showed no significant relationship between Cryptosporidium spp. infection and sex, age, tumor location, cancer grade, or stage. A multivariate logistic regression analysis adjusted for age and sex that included all subjects (patient + control groups, n = 233) showed that the odds of a Cryptosporidium spp. infection were more than three-fold higher in patients than in controls, and more than six-fold higher among men than among women. CONCLUSIONS 1) Cryptosporidium spp. infections occurred significantly more frequently in patients with colorectal cancer (before oncological treatment) compared to controls, independent of age and sex. 2) Cryptosporidium spp. infections were not associated with the colorectal cancer stage, grade, or location or with patient age. 3) Male gender was significantly related to the frequency of Cryptosporidium spp. infections, independent of age and the presence of colorectal cancer.

Abstract
Phytochemical profiles (phenolic compounds, L-ascorbic acid, antioxidant and PPO activities) of 13 different quince varieties and 5 genotypes were studied. Polyphenols were identified by LC-PDA-QTof/MS and quantified by UPLC-PDA and UPLC-FL. A total of 26 polyphenolic compounds found in quince tissues were identified and presented: 9 flavan-3-ols ((-)-epicatechin, procyanidin B2, 3 procyanidin dimers and trimers, and 1 tetramer); 8 hydroxycinnamates, derivatives of caffeoylquinic and coumaroylquinic acid; and 9 kaempferol and quercetin derivatives. The content of total polyphenols was between 1709.43 (genotype 'S1') and 3436.56 mg/100 g dry weight ('Leskovač'). Flavan-3-ols, which are the major class of quince polyphenols, represented between 78 and 94% of the total polyphenolic compounds. The activity of PPO enzyme ranged from 709.85 to 1284.59 ΔU/min, and that of L-ascorbic acid ranged from 5.86 to 26.42 mg/100 g. Some quince varieties and their products characterized by a higher content of phenolic compounds may be selected to promote their positive effect on health.

Abstract
Obstructive sleep apnea syndrome (OSAS) is a common disease characterized by repetitive partial or complete closure of the upper airway during sleep. Cardiovascular disturbances are the most important complications responsible for increased morbidity and mortality. It is suggested that daytime somnolence, chronic fatigue, and nocturnal hypoxemia may further impair muscle function and decrease exercise fitness. The aim of this study was to evaluate cardiopulmonary response to exercise in OSAS patients. One hundred and eleven middle aged (50.2+/-10 yr), obese (BMI 31.0+/-4.6 kg/m2) patients (109 M, 2F) with severe OSAS (AHI 47.2+/-23.1 h(-1)) were enrolled into the study. OSAS was diagnosed with overnight polysomnography and a symptom-limited cardiopulmonary exercise test was performed on a treadmill using Bruce protocol. The results showed that the most frequent reason for exercise termination were: muscle fatigue and/or dyspnea (66+/-), increase in systolic blood pressure>220 mmHg (20%), ECG abnormalities, and chest pain (6%). Although the mean VO2 peak was within the reference value (29.6+/-6 mlO2/kg/min), in 52 patients (46%) VO2 peak was <84% of predicted. Hypertensive response to exercise was diagnosed in 39 of patients (35%). Patients with severe sleep apnea (AHI40>or=h(-1)) were characterized by higher mean blood pressure at rest, at 25%, 50% of maximal work load, at peak exercise and at post-exercise recovery. Several significant correlations between hemodynamic responses to exercise and sleep apnea severity were also noted. We conclude that exercise tolerance can be limited due to hypertensive response in about 20% of patients. Patients with severe OSAS have exaggerated hemodynamic response to exercise and delayed post-exercise blood pressure recovery. Cardiopulmonary response to exercise seems to be related to sleep apnea severity.

Abstract
The present case study reports a case of chronic cough and cough syncope associated with frequent premature ventricular complexes (PVCs). Careful analysis of cough-related symptoms and ECG monitoring led to the suspicion of PVC-induced cough. A coincidence between PVCs and episodes of cough was also documented by a portable multichannel recorder. Moreover, Doppler echocardiography revealed a PVC-induced transient increase in the pulmonary artery blood flow. After exclusion of other possible aetiologies, complete relief of chronic cough and cough syncope was achieved by radiofrequency ablation of the arrhythmogenic focus located in the right ventricular outflow tract. Premature ventricular complexes should be considered as a cause of chronic cough and cough syncope and an interdisciplinary cooperation can lead to successful diagnosis and treatment of this condition.

Abstract
In order to determine a proper method of the treatment of Obstructive Sleep Apnea Syndrome (OSAS) it is essential to demonstrate anatomical abnormalities of upper airways. In this study we would like to estimate how often these anatomical abnormalities occur and what is their influence on OSAS severity. 113 patients underwent laryngological examination, the nasal structure, palate and pharynx were evaluated. The anatomical abnormalities of upper airways were found in 86% patients. The most frequent abnormalities found were nasal disorders, however they were not correlated with OSAS severity. Anatomical abnormalities in more than one level of upper airways were found in 50% of the patients and in those patients OSAS symptoms were the most severe. This may explain why the most frequently performed operations in OSAS patients are not very effective.

Abstract
The aim of this work was to estimate excessive somnolence and frequency of episodes of dozing off during driving a car in patients with obstructive sleep apnea. Result of questionnaire and polysomnographic investigations were analysed in a group of 503 patients. Mean age for the whole group was 49.2 +/- 9.7 of years, BMI 32.1 +/- 1.4 kg/m2 and the value for apnea and hypopnea index 45.4 +/- 24.8. Excessive somnolence during driving was reported by 49.1% of patients. 31.2% of the group notified at least one episode of falling asleep while driving a car. Sleepy drivers (group A) were significantly younger (46.5 +/- 9.2 vs 50 +/- 9.8 years) and had higher values of BMI (34.1 +/- 7 vs 31.1 +/- 5.5 kg/m2) than the others (group B) Results of polysomnographic investigation showed more severe sleep apnea in the group A. Mean value of AHI for this group was 52.5 +/- 26.1 vs 41.6 +/- 23.5 in the group B. Besides, somnolence in many other practical situations was more often considered as a serious problem in the group A.
