Association between Compliance with COVID-19 Restrictions and the Risk of SARS-CoV-2 Infection in Poland.

During the coronavirus disease 19 (COVID-19) pandemic it has become very important to comply with preventive measures. We aimed to assess compliance with applicable restrictions and to explore the links between the level of compliance and the risk of COVID-19. This cross-sectional study included Polish adults who were asked to complete a validated questionnaire. The study period was from 1 November 2020 to 31 January 2021 and a computer-assisted web interview method was chosen to perform the survey. The study involved 562 women and 539 men. COVID-19 was reported in 11.26% of participants. A good level of compliance with the sanitary restrictions was reported for 38.87% of participants, an average level of compliance for 47.96%, and a low level of compliance for 13.17%. A reduced risk of COVID-19 was associated with the following preventive measures: regular use of protective masks, social and physical distancing in public places, regular use of hand sanitizers with high ethanol content, and the use of disposable gloves in public places. Our survey revealed satisfactory public compliance with the pandemic restrictions. Sanitary and epidemiologic measures to prevent the pandemic were shown to be adequate and effective.

Adherence of Obese Patients from Poland and Germany and Its Impact on the Effectiveness of Morbid Obesity Treatment.

This study aimed to investigate and compare the adherence of patients treated for morbid obesity living in Poland and Germany. Methods: A cross-sectional international multicenter survey design was adopted. The study involved 564 adult subjects treated for morbid obesity at selected healthcare facilities in Germany (210 participants) and Poland (354 participants). A validated, custom-made questionnaire based on the literature related to this issue was used. Results: The degree of adherence was higher, but not statistically significant, among Polish patients (83.82% vs. 78.33%, p = 0.26140). Patient adherence was associated with gender, age, level of education, duration of obesity, number of health professionals involved in obesity treatment, and type of obesity treatment (p < 0.05). A positive correlation was observed in the case of age, level of education, and a growing number of health professionals involved in obesity treatment, whereas a negative correlation was observed in the case of the duration of obesity. Patients who underwent bariatric surgery significantly more often followed medical recommendations regarding lifestyle changes, compared to obese participants treated only conservatively. Adherence in the field of obesity treatment significantly increases the percentage of total weight loss and excess weight loss due to applied obesity treatment among both Polish and German groups (p < 0.001). Both the percentage of total weight loss and that of excess weight loss were significantly higher in the group of adherent patients compared to the nonadherent patients (p < 0.00001). The levels of perceived anxiety, stress, and depression were significantly higher in nonadherent patients in both countries. Conclusions: These findings confirm the role of adherence in the effective and satisfactory treatment of morbid obesity. There is a great need to improve patient adherence to overcome the consequences of the obesity pandemic.

Comorbidities and Cofactors of Anaphylaxis in Patients with Moderate to Severe Anaphylaxis. Analysis of Data from the Anaphylaxis Registry for West Pomerania Province, Poland.

Anaphylaxis is a severe, potentially life-threatening systemic hypersensitivity reaction that is still rarely diagnosed. For safety reasons, patients should visit an allergologist to identify potential causes and cofactors of this reaction. This paper presents the analysis of data from the Anaphylaxis Registry gathered over ten years at the Allergy Clinic, Pomeranian Medical University (PMU). A questionnaire-based survey was used for patients visiting the Allergy Clinic to identify potential augmentation factors/comorbidities and/or cofactors of anaphylaxis in patients with a history of moderate to severe anaphylaxis. The registry comprised patients with grade II or higher anaphylaxis. The gathered data concerned chronic comorbidities (cardiovascular diseases, respiratory diseases, and others), recurrence of anaphylaxis, and potential cofactors in anaphylaxis. In the analyzed group, the incidence rate of anaphylaxis was the highest for women aged 19-60 years. Most common comorbidities in patients with moderate to severe anaphylaxis included: cardiovascular diseases, respiratory tract diseases, features of atopy, and thyroid diseases. More than 30% of drug-induced reactions were anaphylactic reactions due to the re-exposure to the same drug, which points to the need for educational initiatives in this area. The incidence rate of anaphylaxis induced by Hymenoptera stings was comparable in patients who had a previous generalized reaction and those who had good tolerance to the previous sting. It is important to take these cofactors into consideration when evaluating patients with anaphylaxis as they may play a role in future anaphylactic reactions.

Cardiovascular Function in Obstructive Sleep Apnea Patients with Controlled Hypertension.

This study investigated hemodynamic characteristics of obstructive sleep apnea (OSA) accompanied by hypertensive disease in obese men, in whom blood pressure was pharmacologically controlled within the normal range, not exceeding 140/90 mmHg. There were 21 severe OSA patients (mean age 54.1 ± 9.3 years, apnea-hypopnea index of 47.1 ± 18.8 episodes per hour) included in the study, in whom OSA was diagnosed with polysomnography. The control group consisted of healthy normotensive age-matched subjects. Hemodynamic profile was recorded nonivasively with impedance cardiography. Brachial blood pressure and radial artery tonometry were performed to capture and reconstruct peripheral radial and central aortic pressure waveforms in both groups of subjects. Compared to healthy men, OSA patients had a significantly higher body mass index (BMI); the mean increase in BMI amounted to 6.4 ± 1.2 kg/m2. The patients also presented significant differences in the hemodynamic profile. The difference consisted of a faster heart rate, higher peripheral pulse pressure, and reduced blood flow acceleration and velocity indices, describing myocardial contractility. Notably, the significance of hemodynamic differences in OSA patients disappeared in the analysis adjusted for the outstanding increase in BMI. In conclusion, the findings strongly suggest that obesity rather than the hypertensive disease per se is a source of hemodynamic consequences in OSA patients.

Does nesfatin-1 influence the hypothalamic-pituitary-gonadal axis in adult males with obstructive sleep apnoea?

There is growing evidence that obstructive sleep apnoea (OSA) influences the hypothalamic-pituitary-gonadal axis (HPG axis) in men. The aim of the study was to assess the association of nesfatin-1 with HPG axis disturbances in OSA. This is a prospective study with consecutive enrolment. It comprises 72 newly diagnosed OSA patients ((AHI: apnoea-hypopnea index) 18 subjects: 5 ≤ AHI < 15; 24: 15 ≤ AHI < 30; 30: AHI ≥ 30) and a control group composed of 19 patients (AHI < 5). All patients underwent polysomnography and fasting blood collection for nesfatin-1, testosterone, luteinising hormone (LH), high-sensitivity C-reactive protein (hsCRP), aspartate transaminase (AST), alanine aminotransferase (ALT), creatinine and glucose. Groups had similar levels of LH, nesfatin-1 and testosterone (p = 0.87; p = 0.24; p = 0.08). Nesfatin-1 was not correlated to LH (p = 0.71), testosterone (p = 0.38), AHI (p = 0.34) or the oxygen desaturation index (ODI) (p = 0.69) either in the whole group, or in sub-groups. The study did not reveal any association between the HPG axis and nesfatin-1 in OSA adult males. It is possible that nesfatin-1 is not a mediator of HPG axis disturbances in adult patients with OSA.

COPD Course and Comorbidities: Are There Gender Differences?

The prevalence of chronic obstructive pulmonary disease (COPD) has increased more rapidly in women than in men during the past two decades. Clinical presentation, comorbidities and prognosis may differ between genders and may influence management decisions. The influence of gender on COPD expression has not been clearly explained to date. Thus, the aim of this study was to evaluate significant differences between women and men suffering from COPD, regarding clinical presentation, pulmonary function test results, comorbidities, and prognosis. We prospectively recruited 470 patients with stable COPD with a history of smoking (152 women, 318 men, mean age 65.5 ± 8.8 vs. 66.6 ± 9.4 years, respectively). Comorbidities and exacerbations were recorded. Spirometry, body plethysmography, carbon monoxide diffusing capacity and 6-min walk tests were performed. The BODE prognostic score was also calculated. We found that women smoked less in comparison to men (30.4 vs. 41.9 pack-years, p < 0.05), showed more exacerbations (2.5 vs. 1.7, p = 0.01), higher forced expiratory volume in 1 s (FEV1%predicted), and increased residual volume/total lung capacity (RV/%TLC), but they had the same intensity of dyspnea. Women showed fewer comorbidities, on average, per patient (5.4 vs. 6.4, p = 0.002), but had a higher prevalence of at least seven comorbidities per patient (48.7% of women vs. 33.0% of men, p < 0.05). Women also had a significantly worse prognosis (4.6 vs. 3.1 BODE score, p < 0.05) that correlated with the number of comorbidities (r = 0.33, p < 0.01). In conclusion, this study strongly supports the existence of different gender phenotypes in COPD, especially regarding exacerbations, comorbidities, and prognosis. The gender difference may indicate a need for a targeted assessment and management of COPD in women and men.

Airway Obstruction in Sleep Apnea Patients.

Obstructive sleep apnea (OSA) is a condition of breathing pathology occurring during sleep, characterized by repeated episodes of upper airway obstruction. The aim of the study was to determine the occurrence of airway obstruction in smoking males with OSA in whom lung function tests had not been performed before. One hundred and four current smokers selected from 1241 patients were enrolled for the research. The subjects included in the study smoked minimum 20 cigarettes a day for at least 10 years. The diagnosis of OSA was confirmed by polysomnography (PSG) in the Sleep Laboratory and subjects were assigned to one of three groups, depending on the severity of OSA. The control group consisted of 30 age-matched male smokers in whom OSA was not confirmed in PSG. Patients from the study and control group scored ≥ 11points in the Epworth Sleepiness Scale. Spirometry, impulse oscillometry, and body plethysmography were used to assess pulmonary function. Airflow limitation in subjects of the control group and OSA patients was confirmed. There were no significant differences in the incidence of bronchial obstruction between the control and study groups, and among the patients of various OSA severity. We conclude that the severity of OSA in smokers does not associate with the presence of airway obstruction. However, the increased peripheral respiratory resistance found in oscillometry did relate to a longer smoking time in OSA patients.

Molecules of Damage-Associated Patterns in Bronchoalveolar Lavage Fluid and Serum in Chronic Obstructive Pulmonary Disease.

Chronic exposure to detrimental environmental factors may induce immunogenic cell death of structural airway cells in chronic obstructive pulmonary disease (COPD). Damage-associated molecular patterns (DAMPs) is a family of heterogeneous molecules released from injured or dead cells, which activate innate and adaptive immune responses on binding to the pattern recognition receptors on cells. This study seeks to define the content of DAMPs in the bronchoalveolar lavage fluid (BALF) and serum of COPD patients, and the possible association of these molecules with clinical disease features. Thirty COPD in advanced disease stages were enrolled into the study. Pulmonary function tests, arterial blood gas content, 6-minute walk test, and BODE index were assessed. The content of DAMPs was estimated using the commercial sandwich-ELISA kits. We found differential alterations in the content of various DAMP molecules. In the main, BALF DAMPs positively associated with age, forced expiratory volume in one second (FEV1), and residual volume (RV); and inversely with PaO2, residual volume/total lung capacity (RV/TLC) ratio, and the disease severity staging. In serum, DAMPS positively associated with the intensity of smoking and inversely with age, PaO2, and TLC. In conclusion, DAMPs are present in both BALF and serum of COPD patients, which points to enhanced both local in the lung environment as well as systemic pro-inflammatory vein in this disease. These molecules appear involved with the lung damage and clinical variables featuring COPD. However, since the involvement of various DAMPs in COPD is variable, the exact role they play is by far unsettled and is open to further exploration.

Association between bone remodeling and inflammatory markers in obstructive sleep apnea in relation to disease severity.

INTRODUCTION    There is growing evidence that obstructive sleep apnea (OSA) influences both bone metabolism and structure. Chitinase­3­like protein 1 (YKL­40) is a novel inflammatory and remodeling marker, the levels of which were shown to increase in OSA. YKL­40 can probably alter the bone turnover. OBJECTIVES    The aim of the study was to assess a possible interplay between YKL­40 and bone turnover markers in patients with different stages of OSA, and to evaluate the relation between bone mass, severity of OSA, and YKL­40 levels. PATIENTS AND METHODS    The study involved 72 male patients with OSA. They were divided into 3 groups according to disease severity, using the apnea-hypopnea index (AHI): group 1 (n = 18; 5≤ AHI <15), group 2 (n = 25; 15≤ AHI <30), and group 3 (n = 29; AHI ≥30). All patients underwent polysomnography and densitometry. Fasting blood samples were collected for YKL­40, C­terminal telopeptide of typeI collagen (CTX), procollagen type 1 N­terminal propeptide (P1NP), and other markers. RESULTS    P1NP differed between groups 1 and 2, as well as groups 1 and 3 (P = 0.02). Group 2 had higher CTX levels than group 1 (borderline significance, P = 0.05). A simple linear regression analysis showed that serum YKL­40 levels were associated with the levels of CTX (P <0.0001, ß = 0.9871) and P1NP (P <0.0001, ß = 0.9780). CONCLUSIONS    Our study might suggest that YKL­40 is associated with bone turnover in OSA. We may assume that this marker influences both bone formation and destruction; thus, OSA could be characterized by preserved bone mineral density.

Obstructive sleep apnea and hormones - a novel insight.

Obstructive sleep apnea (OSA), a disorder characterized by repetitive collapse of the upper respiratory tract during sleep, occurs in about 4% of middle-aged men and 2% of women. The incidence of the disorder is rising due to an increase in obesity and ageing of the population. Patients with obstructive sleep apnea are at elevated risk of some endocrinal and metabolic disorders, which may lead to serious consequences including shortening of life expectancy. The recognition and understanding of interactions between local upper airway dysfunction and its endocrinal consequences is therefore vital. In this review we will focus on the influence of OSA on bone metabolism and endocrine homeostasis.

Dietary and cardio-metabolic risk factors in patients with Obstructive Sleep Apnea: cross-sectional study.

BACKGROUND: Little is known about the role of dietary intake in obstructive sleep apnea (OSA), which could prove important in improving clinical outcomes for people with obesity and/or cardiovascular disease within these populations. Reduction in energy intake typically results in weight loss, markedly improving metabolic parameters and ameliorating OSA severity. The aim of this study was to evaluate the association of dietary and cardio-metabolic risk factors with OSA severity. METHODS: This was a cross-sectional study. A total of 75 volunteers at risk of OSA were recruited from 153 patients suffering from sleep disturbance at the Department of Pulmonology, Allergology and Respiratory Oncology at the Poznan University of Medical Sciences. Polysomnography was used for OSA diagnosis. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Blood pressure, parameters of glucose (fasting glucose, glucose tolerance test) and lipid metabolism (TC, LDL-C, HDL-C, TG) were assessed using routine enzymatic methods. Dietary intake was evaluated by 24-hr dietary recalls and Food Frequency Questionnaire. Ordinal logistic regression models were used for association of background characteristics and dietary intake with OSA severity. All analyses were adjusted for age, sex, BMI, smoking and alcohol intake. RESULTS: A higher percentage of smokers were observed in patients with mild OSA, while alcohol intake was the highest in severe OSA patients. Approximately 60% of the studied patients were self-reported poor sleepers. Results from ordinal logistic regression models showed that higher intakes of alcohol intake were associated with increased odds of severe OSA; whereas higher HDL-C levels were associated with lower odds (OR 0.01; 95% CI [0.0003-0.55]). Significantly higher odds of high OSA severity were observed in patients with disturbed sleep stages and obstructive sleep apnea. Moreover, the investigation of nutrient intake in relation to OSA severity showed that a higher intake of dietary fiber was associated with decreased OSA severity (OR 0.84; 95% CI [0.71-0.98]). CONCLUSIONS: The severity of OSA is related to higher alcohol consumption and disturbed sleep. The significantly lower dietary fiber intake in patients with severe OSA is of particular importance for dietary consulting in clinical practice, which may positively influence cardiometabolic outcomes.

Clinical Utility of Berlin Questionnaire in Comparison to Polysomnography in Patients with Obstructive Sleep Apnea.

The aim of this study was to assess the utility of the Berlin questionnaire (BQ) in adult patients at high risk of obstructive sleep apnea (OSA). The study consisted of 64 patients recruited for the polysomnography diagnostics of sleep respiratory disturbances. The anthropometric assessment included body weight, height, and body mass index (BMI), all related to the risk of OSA. The BQ consisted of the following three categories: 1 - snoring, 2 - daytime somnolence, and 3 - hypertension. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were evaluated. Likelihood ratio was used to assess the diagnostic accuracy. We found that patients were, on average obese; the mean BMI amounted to 31.9 ± 6.0 kg/m2. Polysomnography identified OSA in 73.4% of patients (AHI >5), where the BQ categorized 87.5% of patients at high risk of OSA. Sensitivity of the BQ was 87.2%, specificity 11.8%, PPV 73.2%, and NPV 25.0%. Diagnostic accuracy assessed by the likelihood ratio had a value of 1.00. The BQ had a false discovery rate of 31.2% and misclassification rate of 32.8%. We conclude that the BQ is a sensitive tool that should be used in clinical settings in which the benefit of high sensitivity outweighs the disadvantage of low specificity.

Small Airway Obstruction in Chronic Obstructive Pulmonary Disease: Potential Parameters for Early Detection.

The impulse oscillometry (IOS) is recognized as a complementary method to spirometry in the diagnostics of obstructive pulmonary disorders. The IOS enables to measure total respiratory resistance (R5) and proximal respiratory resistance (R20), with the R5-R20 difference reflecting small airway resistance. This study seeks to evaluate the usefulness of R5-R20, maximal mid-expiratory flow (MMEF), and forced expiratory volume in 3 s/forced vital capacity ratio (FEV3/FVC), in the assessment of small airway obstruction in chronic obstructive pulmonary disease (COPD). One hundred and six COPD patients and 43 control subjects, aged over 55, were investigated. Spirometry and IOS were used to assess pulmonary function. Sensitivity, specificity, positive (PPV) and negative predictive values (NPV) were evaluated. The findings demonstrate significant reductions in FEV3/FVC and MMEF, and an increase in R5-R20 difference in COPD patients; the changes that depended on the severity of airway obstruction. The sensitivity of R5-R20 in reflecting the MMEF was 84%, specificity 44.2%, PPV 72.4%, and NPV 61.3%. We conclude that the R5-R20 difference is superior to spirometry in the assessment of small bronchi obstruction. A high sensitivity of R5-R20 in reflecting the MMEF makes the IOS method particularly useful for detection of mild lung injury, while a high specificity of the spirometric FEV3/FVC ratio makes it useful to exclude obstruction of small airways. Both methods are thus complimentary.

LIPID PROFILE OF POLISH PRIMARY CARE PATIENTS AGED 35-55 YEARS LIVING IN THE DISTRICT OF PLESZEW.

In Poland, more than half of the adult population suffers from lipid disorders. Among the 18 million Polish people with hypercholesterolemia, over 10.8 million are unaware of this problem. To estimate the lipid profile of selected primary care patients in the district of Pleszew (Western Poland), general practitioners (GPs) recruited 681 patients aged 35-55 years in 2011. Fasting serum lipids were evaluated. We found statistically significant differences in all lipid parameters between all younger (35-45 years) and older (46-55 years) patients, between all female and male subjects, between women and men ages 35-45 years; in total cholesterol (TC), LDL-cholesterol (LDL-C) and triglycerides (TG) between younger and older female population; in HDL-cholesterol (HDL-C) and TG between women and men ages 46-55 years. Dyslipidemia, both, newly detected and previously treated, was detected in 591 patients (86.8%): 322 females (84.3%) and 269 males (90.0%). The highest percentage of lipid disorders was found in males aged 46-55 years (91.9%) and the lowest among women aged 35-45 years (78.0%). Age and gender differences in the prevalence of dyslipidemia proved of statistical importance. Among 155 patients on lipid-lowering therapy, only 28 subjects (18.1%) reached the target value of serum lipids. The prevalence of lipid disorders among primary care patients aged 35-55 years in the district of Pleszew was significantly high, and it was proved that dyslipidemia is statistically prominent in males and older patients. Polish healthcare professionals should make more efforts to improve the detection and treatment of lipid disorders.

SUBGALEAL HEMATOMA AS A PERINATAL PRESENTATION OF RARE HEMATOLOGIC PROBLEMS IN NEWBORNS. OWN EXPERIENCE.

INTRODUCTION: Bleeding to the subgaleal space is a rare and often serious complication of childbirth. Delivery with the use of vacuum or forceps is considered as the main risk factor of subgaleal hemorrhage. Reports of other possible causes (including fetal ones) appear rarely. OBJECTIVES: The aim of this study is to present and analyze two unusual cases of bleeding to subgaleal space in neonates delivered through caesarean section, in whom two different concomitant hematologic problems were diagnosed. The authors demonstrate also the mechanisms leading to the formation of subgaleal hematoma as well as discuss the impact of the final diagnosis on the course of the perinatal period and the need to modify medical practice in a variety of clinical situations in both newborns and their mothers. MATERIAL AND METHODS: Authors present two consecutive cases of severe subgaleal hemorrhage. RESULTS: In the first newborn hemophilia was finally diagnosed. The second neonate was diagnosed with neonatal alloimmune thrombocytopenia. CONCLUSIONS: Subgaleal hemorrhage is a rare complication of delivery. In severe cases, other possible risks should be considered apart from the traumatic delivery only. An early identification of potential hematological risk factors can influence the effectiveness of the treatment and help to modify the follow-up of both the infant and its mother.

[Complete regression of eyeball metastasis secondary to non-small-cell lung cancer with Cisplatin and Vinorelbin therapy]. / Calkowita remisja przerzutów do galek ocznych w przebiegu raka niedrobnokomórkowego pluca po zastosowanej chemioterapii cisplatyna i vinorelbina.

Lung cancer is the most common cause of cancer mortality in men and the fourth most common in women. The most frequent location of distant metastases are: the pleura, liver, suprarenal gland, brain, bones, pericardium and subcutaneous tissue. Others locations of distant metastases are very rare. This case report presents a 61-year-old female patient treated with Cisplatin and Vinorelbin therapy for posterior segment of eyeballs metastases secondary to NSCLS. Fluorescein angiography, computed tomography with contrast intensification and magnetic resonance were compared during the 3-month treatment period. After the 4-rd cycle of chemiotherapy (Cisplatin and Vinorelbin) one elevated choroidal mass on the posterior wall in the superiotemporal quadrant of the right eyeball and one mass in the lower-inside quadrant of the left eyeball had completely disappeared. The retina and a retinal pigment epithelial layer were flattened. Combining Cisplatin and Vinorelbin was optimal treatment for our patient with intraocular metastasis of NSCLC. The first clinical symptom of nonsmall cell lung cancer was blindness. The described case confirms, that distant metastases of non-small cell lung cancer also occur in atypical places at be a cause of great diagnostic problems and can delay start of anticancer treatment.

Antiproliferative activity of various Uncaria tomentosa preparations on HL-60 promyelocytic leukemia cells.

The woody Amazonian vine Uncaria tomentosa (cat's claw) has been recently more and more popular all over the world as an immunomodulatory, antiinflammatory and anti-cancer remedy. This study investigates anti-proliferative potency of several cat's claw preparations with different quantitative and qualitative alkaloid contents on HL-60 acute promyelocytic human cells by applying trypan blue exclusion and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide reduction assay (MTT). By standardization and statistical comparison of the obtained results pteropodine and isomitraphylline are indicated to be most suitable for standardization of medical cat's claw preparations.
