Retaining Healing Hands: A Transnational Study on Job Retention Interventions for the Healthcare Workforce.

Healthcare organizations worldwide face challenges in retaining their healthcare workforce, with individual and organizational factors influencing their intentions to leave. This study conducted eight online co-creation workshops and four Delphi sessions to gain qualitative and in-depth insights into job retention interventions, involving healthcare workers, hospital managers, and policymakers. A thematic analysis was conducted, resulting in multiple interventions that were clustered in four pre-defined themes: professional and personal support, education, financial incentives, and regulatory measures. Professional and personal support interventions included regular interprofessional team meetings, leadership training programs, self-scheduling and sabbaticals, support for administrative and non-clinical work, and the provision of psychological counselling. Educational interventions encompassed facilitating development opportunities, periodic evaluations, onboarding, mentorship programs, and peer support groups. Financial incentives included the provision of competitive salaries, adequate infrastructure, extra benefits, transport possibilities, and permanent employment contracts. Regulatory measures addressed the need for complementary legislation across various levels, fixed healthcare worker-to-patient ratio, and instruments to monitor workload. To optimize retention strategies, healthcare organizations should tailor these interventions to address the unique factors influencing their workforce's intentions to leave within their specific context. The study concludes that combining personal and professional support, educational opportunities, financial incentives, and regulatory measures is necessary because there is no one-size-fits-all solution.

Sources of parental knowledge about the safety of vaccinations in Poland.

There has been a recent increase in the number of parents refusing vaccination for their children in many European countries, including Poland. This observation necessitates the need to understand parental knowledge in regard to mandatory vaccination of children in these countries. A cross-sectional survey was conducted in 2016 on 1239 parents or legal guardians of preschool and school children in the Silesian Voivodship (Poland) to evaluate their hesitancy in acquiescing to their children mandatory immunization and the relation to this habit in regard to the use of informational sources on children vaccination system in Poland. Medical doctors often provide the basic source of information about vaccination to parents. About one-third (29%) of the respondents from the survey deemed the qualification system for vaccination as either inadequate or bad. 16.9% of the respondents surveyed declared that information received from physicians regarding vaccinations were either incomplete or unconvincing. Results of multivariable analyses confirmed that respondents are less likely to seek information about mandatory vaccinations from medical professionals and more often to misjudged vaccination's qualification system. Participants who used less informative sources (e.g. leaflets) and those with a lower level of education were more likely to avoid vaccination. Greater emphasis on the quality of information provided by medical professionals is crucial in order to avoid doubts about vaccination and to create proper attitudes and adherence to vaccination schedules.

Comparison of spirometric results obtained from the sitting and standing position in children participating in an epidemiological study.

INTRODUCTION: It is recommended that spirometric testing in children be completed while sitting. Our experience indicates that children prefer standing during spirometry. AIM: We sought to compare spirometric results obtained from the sitting (SIP) and standing (STP) positions. MATERIAL AND METHODS: Two testing sessions were performed in random order (SIP vs. STP: 30-45 min apart) in 118 children (7-13 years), attending one, randomly selected, primary school (response rate: 92%). RESULTS: Acceptable quality was found in 77.9% of STP and 77.1% of SIP maneuvers. Higher values of spirometric variables on STP, compared to SIP, were obtained for forced vital capacity (FVC) (2.12 ±0.41 l vs. 2.11 ±0.39 l) and forced expiratory volume in 1 s (FEV1) (1.78 ±0.36 l vs. 1.77 ±0.35 l) but the differences were not statistically significant. Relative between-position differences (RBPD) ≤ 5% were found with the following frequencies: FVC: 56.4%, FEV1: 69.2%, PEF: 21.7%, and FEF25-75: 24.3%. Similar patterns were found for FEF25, FEF50, and FEF75. Relative between-position differences were related to age in the case of FEV1 (p = 0.005), FEF25 (p = 0.02), and FEF25-75 (p = 0.01) where older children had smaller RBPD. Forced vital capacity RBPD was lower (p = 0.01) in subjects with current wheeze; PEF RBPD were lower (p = 0.02) in children with asthma. CONCLUSIONS: In epidemiological studies, the position of spirometric testing does not affect the results of lung function assessment.

Non-alcoholic fatty liver and advanced fibrosis in the elderly: Results from a community-based Polish survey.

BACKGROUND & AIMS: Development of non-alcoholic fatty liver (NAFL) is dependent on metabolic factors occurring at an increased frequency with advancing age. Until now, few studies have explored the prevalence of NAFL in aged populations. Our study aimed to determine the prevalence of NAFL and advanced fibrosis in the elderly population participating in a national survey of a community-based elderly cohort. METHODS: A total of 3003 participants (mean age 79.6 years, 46.8% male) were enrolled in the study, after applying the following exclusion criteria: individuals younger than 65 years old (n=829) and those with positive serological biomarkers of HBV or HCV infection (n=391), chronic alcohol ingestion (n=727) or incomplete data records (n=745). Based on the fatty liver index (FLI), the participants were classified into three categories: FLI<30 (no NAFL), 30≤FLI<60 (borderline) and FLI≥60 (NAFL). According to the non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS), the participants were divided into three advanced fibrosis risk categories: NFS<-1.455 (low risk), -1.455≤NFS≤0.676 (intermediate risk) and NFS>0.676 (high risk). RESULTS: The prevalence of NAFL in the general population was 37.2%; the prevalence reached 51.4% in participants 65-70 years of age and decreased with advancing age (P<.0001). The prevalence of advanced fibrosis was 7.79% (14.8% in the NAFL population) and increased with advancing age (P<.005). CONCLUSIONS: The prevalence of NAFL and metabolically driven advanced fibrosis are relatively common in the elderly population, and these hepatic conditions run in adverse directions with advancing age.

Determinants of vaccine hesitancy

Vaccine hesitancy is a worrying phenomenon due to its range and health-related consequences. Secondary epidemiological data on the current situation of vaccination in Poland were analyzed. The source of the analyzed data were obtained from the reports of the National Sanitary Inspection and the National Institute of Public Health­National Institute of Hygiene in Warsaw. Legal basis on vaccination and the responsibilities of physicians related to these regulations were also discussed. Considering the opinions of ECDC experts, factors influencing vaccine hesitancy were identified. Attention was paid to the activities of the anti-vaccination movements, their range of activity and a strategy of action.

Predictive Value of Fractional Exhaled Nitric Oxide (FeNO) in the Diagnosis of Asthma for Epidemiological Purposes-An 8-Year Follow-Up Study.

At the population level, respiratory symptoms in children can be estimated cross-sectionally. However, such methods require additional objective support parameters, such as the measurement of fractional exhaled nitric oxide (FeNO). The aim of the present study was to analyze if the FeNO value measured at baseline can have a predictive value for asthma-like symptoms after 8 years of measurement. METHODS: The follow-up included 128 (out of 447) children, 70 girls and 58 boys. The FeNO was measured at baseline only. The prevalence of asthma-like symptoms was measured with the adopted version of the ISAAC questionnaire. RESULTS: After 8 years of FeNO measurement, 5 new cases of asthma, 2 cases of attacks of dyspnoea, 1 case of wheezy in the chest, and 18 cases of allergic rhinitis occurred. The FeNO values, measured at the baseline of the study, for new cases of the above diseases were 53.4 ± 75.9 ppb, 11 ± 1.5 ppb, 12.0 ppb, and 16.3 ± 12.4 ppb, respectively. The best diagnostic accuracy parameters were found in the new cases of asthma, where the sensitivity was 40.0%, the specificity was 98.6%, and the AUC was 66.6%. The diagnostic odds ratio was 46.9 when considering the FeNO cut-off >35 ppb. CONCLUSIONS: The FeNO measurement is a fair method for asthma prognosis in early school-aged children with asthma-like symptoms measured on the population level but requires further confirmation at the clinical level with more accurate diagnostic tools.

Chronic Kidney Disease Increases Mortality and Reduces the Chance of a Favorable Outcome in Stroke Patients Treated with Mechanical Thrombectomy-Single-Center Study.

Background/Objectives: Chronic kidney disease (CKD) is identified as a risk factor for the occurrence of ischemic stroke. There is substantial evidence that CKD is linked to a worse prognosis and higher mortality rates in stroke patients. This study aimed to evaluate the characteristics and factors affecting favorable outcomes and mortality in patients treated using mechanical thrombectomy (MT) for ischemic stroke, with particular emphasis on patients suffering from CKD. Methods: The retrospective study included an analysis of data from 723 patients (139; 19.4% had CKD) with ischemic stroke treated with MT between March 2019 and July 2022. Results: Patients with CKD were significantly older (median age 76.5 vs. 65.65, p < 0.001) and more often female (59.7% vs. 42.6%, p < 0.001). CKD decreased the likelihood of achieving a favorable outcome (0-2 points in modified Rankin scale; OR: 0.56, CI95%: 0.38-0.81) and increased mortality (OR: 2.59, CI95%: 1.74-3.84) on the 90th day after stroke. In addition, CKD was associated with intracranial hemorrhage (ICH) in patients who underwent posterior circulation MT (13.85% vs. 50%, p = 0.022). In patients with CKD, inter alia, higher levels of C-reactive protein (OR: 0.94, CI95%: 0.92-0.99) reduced the chance of a favorable outcome. In addition, the occurrence of ICH in patients with CKD increased mortality on the 90th day after stroke (OR: 4.18, CI95%: 1.56-11.21), which was almost twice as high as in patients without CKD (OR: 2.29, CI95%: 1.54-3.40). Conclusions: Patients suffering from CKD had a lower probability of achieving a favorable outcome and had increased mortality following MT for ischemic stroke. It is crucial to understand the variations between patients with unimpaired and impaired renal function, as this could aid in predicting the outcomes of this method.

Life situation of a caregiver of a child with congenital heart defect and/or other cardiac problems: structure and preliminary validation of a new questionnaire.

Background: Illness in a child with cardiac disease causes stress, brings additional responsibilities, reorganizes family life, and changes the functioning of the family. Aim: This study aimed to validate a new questionnaire evaluating the life situations of caregivers/parents of children with congenital heart disease (CHD) and/or other cardiac diseases (OCD). Materials and methods: The questionnaire comprised 10 questions aimed at assessing the life situation of an ill child's caregiver in two main areas: personal and spiritual. The total score of the questionnaire assessing the life situation of the caregiver of a child with a CHD and/or OCD can range from 0 to 32 points, with scores <26 indicating a poor, 25 to 32 indicating an average, and >32 indicating a good level of life situation in the personal sphere of the caregiver. The questionnaire was assessed using Cronbach's alpha tests, and repeatability was assessed using Cohen's Kappa test (retest) within a time interval of two to 4 weeks from the first measurement. Results: The research covered 50 respondents. Cohesion in the personal sphere obtained a satisfactory value of Cronbach's α = 0.72, in the spiritual sphere: Cronbach's α = 0.83, and the result common for both sections was: Cronbach's α = 0.66. Conclusion: The Life Situation Assessment Questionnaire for caregivers of children with CHD and OCD is a reliable and homogeneous tool for measuring the functioning of parents in the event of a child's illness.

General health and its relation to the quality of life and alcohol consumption in a Polish cohort of medical students - preliminary results of POLLEK survey.

Introduction: First-year students of medicine are at higher risk of stress related to the new environment and study overload. Such factors can play a role and have an impact on their quality of life and general health status which can cause possible problems with alcohol use. The aim of the study is to assess the relationship between mentioned factors in the Polish cohort of first-year medical students. Materials and methods: The quality of life has been assessed within the WHOQOL-BREF questionnaire, the general health status was assessed via GHQ28, and alcohol consumption was assessed the by AUDIT questionnaire. Due to the lack of signature informed consent and lack of data, 381 (72%) students out of 525 were included in the final analysis. Result: The majority of the 1-year students were females 68%; (n = 259) vs. 32% (n = 122) males. Half of the students had lowered risk of distress. However, females had a higher risk of having higher scores in GHQ-28 than males. In relation to the assessment of the quality of life, the students with a lower level of distress (<32 points in GHQ-28) had better results in each WHOQOL domain. There was no association between general health status and alcohol use. For the students who had possible problems with alcohol use the OR was 1.15 95% CI (0.73-1.80) and for students who were probably addicted OR was 1.07 95% CI (0.33-3.41). Conclusion: The total quality of life in first-year Polish medical students is relatively high; however, half of them suffer because of distress and around 30% have some alcohol problems. Females are more likely to have higher GHQ-28 scores than males.

Components of the metabolic syndrome in girls with Turner syndrome treated with growth hormone in a long term prospective study.

Background: Components of the metabolic syndrome are more common in patients with Turner syndrome (TS) than in the general population. Long-term growth hormone (GH) treatment also affects the parameters of carbohydrate metabolism. Therefore, all these factors should be monitored in girls with TS. Objective: To assess the occurrence of metabolic syndrome components in TS girls before GH treatment and to monitor changes in metabolic parameters throughout GH therapy. Patients and method: 89 TS patients were enrolled in the study. Clinical and laboratory data after the 1st (V1), 3rd (V3), 5th (V5) and 10th (V10) year of GH therapy was available respectively in 60, 76, 50 and 22 patients. The patients' biochemical phenotypes were determined by glucose 0', 120', insulin 0', 120', HOMA-IR, Ins/Glu ratio, HDL-cholesterol and triglycerides (TG) concentration. Results: Obesity was found during V0 in 7.9% of patients,V1 - 5%, V3 - 3.9%, V5 - 2%, V10 - 0%. No patient met diagnostic criteria for diabetes. A significant increase in the basal plasma glucose 0' was found in the first five years of therapy (pV0-V1 < 0.001; pV0-V3 = 0.006; pV0-V5 < 0.001). V10 glucose 120' values were significantly lower than at the onset of GH treatment (pV0-V10 = 0.046). The serum insulin 0' and 120' concentrations as well as insulin resistance increased during treatment. No statistically significant differences in serum TG and HDL-cholesterol levels during GH therapy were found. Conclusion: The development of insulin resistance and carbohydrate metabolism impairment have the greatest manifestations during GH therapy in girls with TS. Monitoring the basic parameters of carbohydrate-lipid metabolism in girls with TS seems particularly important.

The correlation of vitamin D level with body mass index in women with PCOS.

OBJECTIVES: The aim of this study is to analyze correlation between vitamin D level and BMI in polycystic ovary syndrome (PCOS) women. MATERIAL AND METHODS: The study group consisted of 311 patients with PCOS. Patients were categorized according to four phenotypes. All of the women participating in the study had their blood tested in the appropriate phase of the menstrual cycle and after proper preparation for the tests. The ultrasound examination and anthropometric measurements were performed. RESULTS: Vitamin D concentration was assessed in all study subgroups. The majority of patients had vitamin D deficiency or insufficient level. Variables included in the study, such as level of vitamin D, low density lipoprotein (LDL), sex hormone binding globulin (SHBG), testosterone, androstenedione, Anti-Müllerian Hormone (AMH) and BMI were correlated. A negative correlation was observed with the the level of SHBG, vitamin D and AMH. Subsequently, positive correlations were shown with testosterone, LDL and free testosterone level. An analysis of the correlation between BMI and vitamin D concentration showed that in phenotype I of PCOS this correlation was statistically significant and in the remaining PCOS phenotypes the correlation was close to statistical significance. CONCLUSIONS: Most PCOS patients have a deficiency or insufficient level of vitamin D. Women with PCOS have shown a significant negative correlation between BMI and SHBG serum level and between BMI and AMH level. A positive correlation exists between BMI and total and free testosterone and LDL. There is a negative correlation between BMI and vitamin D level in PCOS patients and in phenotype I this correlation was statistically significant.

Retaining Healthcare Workers: A Systematic Review of Strategies for Sustaining Power in the Workplace.

The shortage of healthcare workers is a growing concern. The COVID-19 pandemic and retirement wave have accelerated turnover rates. This systematic review aimed to identify and analyse the existing interventions for job retention of healthcare workers, in terms of nurses and physicians, in a hospital setting. A comprehensive search was conducted within three electronic databases, guided by the preferred reporting items for systematic review and meta-analyses (PRISMA) and synthesis without meta-analysis (SWiM) guidelines, this resulted in 55 records that met the inclusion criteria. The intervention outcomes are categorized into substantial themes: onboarding, transition program to a different unit, stress coping, social support, extra staffing, coping with the demands of patient care, work relationships, development opportunities and department resources, job environment, work organization, recruitment approach, and technological innovations. Considering the literature, onboarding programs and mentoring for nurses and physicians are recommended. Additionally, other interventions described in this review could positively affect the retention of nurses and physicians. When selecting an intervention for implementation, managers and human resources should consider the intervention that matches the determinant of intention to leave of their healthcare workers and the hospital's mission, vision, and values. Sharing the success stories of implemented interventions may benefit healthcare organizations.

Potential benefits of one­time gastroscopy in search for precancerous conditions.

INTRODUCTION: Precancerous conditions for esophageal (EA) and gastric adenocarcinoma (GA) are Barrett's esophagus (BE) and atrophic gastritis (AG), respectively. Their surveillance is crucial for the detection of early lesions. OBJECTIVES: The study aimed to assess whether one­timeesophagogastroduodenoscopy (EGD) in search for precancerous conditions would be effective in the population with low­to­moderate esophageal and gastric cancer risk. PATIENTS AND METHODS: A total of 5984 individuals who underwent diagnostic EGD in 3 endoscopic centers, from March 2018 to October 2019, were analyzed to assess the age of occurrence of precancerous conditions and cancers. Age distribution of the patients with malignant gastric and esophageal tumors registered in the national cancer registry from 2014 to 2017 was analyzed. RESULTS: In comparison with individuals below 40 years old, the risk of EA and GA diagnosis increased at the age of 60 to 64 years (odds ratio [OR], 12.1; 95% CI, 1.5-98.6), gastric and esophageal dysplasia at the age of 55 to 59 years (OR, 3.6; 95% CI, 1.3-9.7), and BE and AG at the age of 40 to 44 years (OR, 1.6; 95% CI, 1.04-2.4). The number of procedures per 1 cancer that could be potentially avoided was 236, 235, 290, 360, 394, and 344 for the age groups of 40-44 years, 45-49 years, 50-54 years, 55-59 years, 60-64 years, and 65-69 years, respectively. The assessed potential benefit­to­harm ratio was 47, 38, 31, 28, and 32 for the age groups of 40-49 years, 50-54 years, 55-59 years, 60-64 years, and 65-69 years, respectively. CONCLUSIONS: One­time EGD in search for precancerous conditions could be potentially applicable in individuals between 40 and 69 years of age.

Comparison of Repair vs Replacement in Calcific and Rheumatic Mitral Disease.

BACKGROUND: The benefit of repair over replacement of rheumatic or calcified mitral valve (MV) is debatable. METHODS: Patients who underwent MV repair or replacement for rheumatic or calcified MV disease between 2006 and 2020 were identified in the Polish National Registry of Cardiac Surgery Procedures. Patients who underwent additional procedures other than coronary artery bypass grafting or tricuspid valve surgery, as well as redo or emergency cases, were excluded. The long-term survival was verified based on National Health Fund registry data. The survival was compared between MV repair and replacement in the whole cohort and after propensity score matching. RESULTS: We included 4338 patients: 1859 (43%) with pure mitral regurgitation and 2479 (57%) with mitral stenosis. MV was repaired in 543 patients (29%) with pure regurgitation and 126 (5.1%) with stenosis (P < .001). In total, 984 (23%) patients underwent concomitant coronary artery bypass grafting and 1358 (32%) tricuspid valve surgery. MV repair improved survival (hazard ratio 0.81; 95% CI 0.68-0.97; P = .022) in patients with no mitral stenosis, and had no effect in mitral stenosis (hazard ratio 1.17; 95% CI 0.85-1.59; P = .332). The results were confirmed in propensity-matched cohorts. The freedom from MV reoperation at 10 years was 95.5% ± 1.2% after repair and 96.0% ± 0.7% after MV replacement (P = .416) in the absence of stenosis and 91.8% ± 3.4% after repair vs 95.9% ± 0.5% after replacement in patients with mitral stenosis (P = .065). CONCLUSIONS: Repair of rheumatic/calcified mitral valve should be a preferred option in patients with no mitral stenosis, but confers no benefit if mitral stenosis is present.

The Accuracy of a Screening Tool in Epidemiological Studies-An Example of Exhaled Nitric Oxide in Paediatric Asthma.

Diagnostic tests are widely used in medicine, especially in the clinical setting. The doctor's decision regarding the treatment process is mostly based on the result of the diagnostic test. The value of the test is expressed by its accuracy. It is easier to verify the accuracy of a diagnostic test in a clinical setting in comparison to an epidemiological setting. Moreover, a very good test may not work in epidemiological settings in the same effective way as in a clinical setting, especially because the accuracy is affected by the prevalence of the disease. The aim of the study is to assess the accuracy of FeNO measurement in different respiratory disorders or symptoms, including their prevalence, in a childhood population. The secondary aim is to suggest the optimal FeNO cut-off for epidemiological screening for respiratory diseases and symptoms. METHODS: The cross-sectional study included 447 children (50.8% boys and 49.2% girls) aged 6-9 years. An adapted version of the ISAAC questionnaire was used for the assessment of the respiratory status. FeNO was measured with an electrochemical device (Niox Mino) according to ERS/ATS recommendations. For interpretation, the FeNO cut-off values of 20 parts per billion (ppb), 25 ppb and 35 ppb were applied taking the real-life prevalence of the disease or symptoms into consideration and also for simulated prevalences of 20%, 30%, 40%, 50% for the interpretation of the accuracy of the test. The accuracy was calculated according to the following formula: Accuracy = (Prevalence) (Sensitivity) + (1- Prevalence) (Specificity). The area under the curve was calculated based on logistic regression. RESULTS: For all respiratory outcomes, FeNO accuracy decreased with increasing prevalence, and in general the area under the curve (AUC) was low. The highest FeNO accuracy was found for any asthma diagnosis (with possible coexisting diseases/symptoms), i.e., 78.6%, 92.8% and 88.5% for FeNO cut-offs >19 ppb, >24 ppb and >34 ppb, respectively. The AUC was 0.628. For the same FeNO cut-offs, the accuracy of an asthma diagnosis without any coexisting diseases and symptoms was 81.2%, 87.5%, 92.9%, respectively, with an AUC of 0.757. CONCLUSION: FeNO accuracy decreases with increasing prevalence of the respiratory disease and symptoms. The best accuracy for the FeNO cut-off in the screening of asthma for epidemiological purposes is 35 ppb. For isolated asthma, the best accuracy for FeNO was 92.9%.

The Effect of Obesity on Fractional Exhaled Nitric Oxide in School-Aged Children.

BACKGROUND: Fractional exhaled nitric oxide (FeNO) is recognized as a biomarker of eosinophilic inflammation. Current literature shows evidence that FeNO is influenced by many factors. Obesity is a chronic inflammatory state. In this study, we considered obesity as a potential factor that influences FeNO levels. The aim of the study was to analyze the association between body mass index (BMI, body mass (kg)/height (m)2) and FeNO levels in a young group of children. METHODS: The participants in the study were 506 school-aged children who were randomly selected from primary schools located in Silesian Voivodship (Poland). The modified version of the Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was used to assess the respiratory system status of children. FeNO was measured in 447 children according to European Respiratory Society and America Thoracic Society (ERS/ATS) recommendations. Body mass and height were measured by a medical body composition analyzer. BMI was defined and interpreted with Palczewska's percentile charts. RESULTS: In the study group there were 49.9% (n = 223) boys and 50.1% (n = 224) girls. The frequency of normal BMI was 76.8% (n = 172), overweight 13.7% (n = 31) and obesity 9.4% (n = 21) in girls, while the normal BMI was found in 71.3% (n = 159), overweight 11.6% (n = 26) and obesity 17% (n = 38) in boys, the differences not statistically significant (p = 0.05). The mean FeNO value in children with obesity was 16.1 ± 12.5 ppb, in children with normal BMI 15.8 ± 15.5 ppb and the lowest FeNO values were in children with overweight 15.3 ± 13.0 ppb; p = 0.9. The FeNO values after adjusting for age, sex, BMI and symptoms from respiratory system were depended on age and respiratory symptoms only. CONCLUSIONS: In 6-9 year old school children, FeNO levels are associated with age and health in relation to the respiratory system. The BMI should not be included when considering reference values for FeNO.

Screening Accuracy of FeNO Measurement for Childhood Asthma in a Community Setting.

(1) Background: The exhaled fractional nitric oxide is a well-recognized biomarker used in clinical settings for controlling and managing asthma. Less is known about the value of Fractional Exhaled Nitric Oxide (FeNO) measurement in epidemiological studies on childhood asthma, although available evidence suggests that an increased FeNO is associated with an increased risk of asthma. (2) Aim: The aim of the study was to assess FeNO accuracy in the identification of children with asthma, participants in a population-based respiratory survey. (3) Material and methods: The cross-sectional study included 449 children, 224 (49.9%) boys and 225 (50.1%) girls aged 6−10 years. The FeNO was measured in 449 children; Spirometry tests were completed with 441 children, but technically acceptable spirometry was done in 350. All participants fulfilled the questionnaire (ISAAC) for assessment of the status of their respiratory system on which diagnosis was based on. FeNO and Spirometry were performed according to ERS/ATS recommendations. (4) Results: The FeNO was significantly higher in asthmatic children (n = 22): 27.3 ± 21.3 ppb; with allergic rhinitis (n = 106): 9.9 ± 21.6 ppb, with atopic dermatitis (n = 67) 20.8 ± 25.0 ppb, with an asthmatic tendency (n = 27): 19.8 ± 16.0 ppb in comparison to children without any respiratory/atopy symptoms. The highest diagnostic odds ratio and area under the curve were found in any treated asthma or asthma without any atopic symptoms in relation to FeNO cutoff > 35 ppb; DOR 4.85 and 8.37; AUC 0.615 and 0.795, respectively. The adjustment for spirometry parameters did not improve the diagnostic accuracy of FeNO. In each FeNO cutoff, there were more false positive than true positive subjects. (5) Conclusions. The best diagnostic accuracy of FeNO was for isolated asthma without any atopy against children without any coexisting respiratory or allergic disease. The sensitivity and specificity did not reach the required values for a good screening tool; therefore, it should not be used in epidemiological settings.

The use of protective masks and the level of arterial oxygen saturation at rest and after exercise.

BACKGROUND: Studies of influenza, and human coronaviruses provide evidence that the use of a medical mask can prevent the spread of infectious droplets from an infected person to someone else. After global public health emergency of coronavirus SARS-CoV-2 causing illness of COVID-19 was changing frequency of wearing a mask. Therefore, study was undertaken to assess whether the use of protective masks affects the level of oxygen saturation during rest and during exercise. MATERIAL AND METHODS: The test consisted of a non-invasive measurement of oxygen saturation by percutaneous determination of arterial oxygen saturation with the use of the pulse oximeter. Oxygen saturation was measured during rest and after physical exertion performed without a protective mask (2 types of masks were used: surgical and FFP2), as well as during rest and after physical exertion performed with the use of a protective mask. The analysis of the oxygen saturation, heart rate, blood pressure and respiratory rate included data on 48 subjects. RESULTS: Comparing the post-exercise and pre-exercise values showed a significant difference between all of them. There were no differences found in any variables according to the mask/no-mask status. CONCLUSIONS: A short-term physical exercise performed in a group of healthy young people using protective masks did not affect oxygen saturation, heart rate, blood pressure and respiratory rate.

The relation of esophagogastroduodenoscopy time and novel upper gastrointestinal quality measures.

OBJECTIVES: Various measures of esophagogastroduodenoscopy (EGD) quality have been proposed so far and the examination time was one of the first. The aim of the study was to compare the procedure time with novel novel quality measures - composite detection rate (CDR) and endoscopist biopsy rate (EBR). METHODS: It was prospective observational study. A total of 880 diagnostic EGDs conducted from 01.2019 to 07.2019 have been enrolled in the study. RESULTS: Median EGD time was 4.2 min. Procedures of longer duration were marked with higher CDR (26.3% vs. 11.8%; P < 0.0001), higher EBR (44.9% vs. 12.3%; P < 0.0001), and better upper gastrointestinal neoplasm (UGN) detection (1.8% vs. 0%; P = 0.004) in comparison with procedures of shorter duration. The procedures were divided into 4 groups based on the time quartiles (group 1 <3.3 min; group 2 3.3-4.2 min; group 3 4.2-5.3 min; group 4 >5.3 min). The odds ratios of groups 2, 3, and 4 for biopsy rate were 2.42 (95% CI, 1.33-4.55), 4.33 (95% CI, 2.46-7.94), and 5.51 (95% CI, 3.18-10.03), respectively, in comparison with group 1. The odds ratios of groups 2, 3, and 4 for CDR were 3.18 (95% CI, 2.03-4.97), 5.46 (95% CI, 3.51-8.50), and 23.44 (95% CI, 14.3-38.4), respectively, in comparison with group 1. CONCLUSIONS: The procedure time is related to novel metrics - CDR and EBR. It is also related to UGN. Based on our findings it could be concluded that EGD should not last less than 4.2 min.

Assessment of Satisfaction with Health Services among Prisoners-Descriptive Study.

AIM: The aim of the study was to assess the access of prisoners to healthcare services, as well as the level of satisfaction with the provided services and health assessment among prisoners. METHODS: The research was conducted in one of the penitentiary centers in Poland among people jailed between 1 January to 31 January 2020. The response rate of the self-administrated questionnaire was 52.05% (469/901) participants. There were 389 men and 77 women. RESULTS: Prisoners assessed access to health services including GP doctors, specialist doctors, dentists, and hospitals in 3 categories: "bad" ranged: 27.03-67.60%; "medium" ranged: 22.54-53.57%; "good" ranged: 7.02-33.96% depending on the type of arrest, but no statistical significance was demonstrated. Satisfaction with the health services defined as "bad" ranged: 25.00-61.11%; "medium" ranged: 18.97-55.56%; "good" ranged: 5.56-34.62% depending on the type of arrest but no statistical significance was demonstrated. Of 469 prisoners, 215 prisoners (45.84%) declared no addictions. The frequency of addiction does not differ depending on the place/type of punishment served (p = 0.9). In turn, 317 prisoners (68%) declared no chronic diseases. CONCLUSIONS: Most of the prisoners described access to health services as "bad", except female prisoners from a semi-open facility. In turn, satisfaction with healthcare services was most often assessed as "bad", except for temporarily arrested men and female prisoners from a semi-open facility.
