Phenotypes of Polish primary care patients using hierarchical clustering: Exploring the risk of mortality in the LIPIDOGEN2015 study cohort.

BACKGROUND: Comorbidities in primary care do not occur in isolation but tend to cluster together causing various clinically complex phenotypes. This study aimed to distinguish phenotype clusters and identify the risks of all-cause mortality in primary care. METHODS: The baseline cohort of the LIPIDOGEN2015 sub-study involved 1779 patients recruited by 438 primary care physicians. To identify different phenotype clusters, we used hierarchical clustering and investigated differences between clinical characteristics and mortality between clusters. We then performed causal analyses using causal mediation analysis to explore potential mediators between different clusters and all-cause mortality. RESULTS: A total of 1756 patients were included (mean age 51.2, SD 13.0; 60.3% female), with a median follow-up of 5.7 years. Three clusters were identified: Cluster 1 (n = 543) was characterised by overweight/obesity (body mass index ≥ 25 kg/m2), older (age ≥ 65 years), more comorbidities; Cluster 2 (n = 459) was characterised by non-overweight/obesity, younger, fewer comorbidities; Cluster 3 (n = 754) was characterised by overweight/obesity, younger, fewer comorbidities. Adjusted Cox regression showed that compared with Cluster 2, Cluster 1 had a significantly higher risk of all-cause mortality (HR 3.87, 95% CI: 1.24-15.91), whereas this was insignificantly different for Cluster 3. Causal mediation analyses showed that decreased protein thiol groups mediated the hazard effect of all-cause mortality in Cluster 1 compared with Cluster 2, but not between Clusters 1 and 3. CONCLUSION: Overweight/obesity older patients with more comorbidities had the highest risk of long-term all-cause mortality, and in the young group population overweight/obesity insignificantly increased the risk in the long-term follow-up, providing a basis for stratified phenotypic risk management.

May Measurement Month 2021: an analysis of blood pressure screening results from Poland.

May Measurement Month 2021 (MMM21) is the fourth edition of the global initiative in Poland initiated by the International Society of Hypertension (ISH) and aimed at raising awareness of hypertension and the need for blood pressure (BP) screening. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 132 sites - between May and September 2021. Blood pressure was measured in 1699 subjects (mean age: 40.8 ± 17.0 years; 68.8% females). After multiple imputation, the age and sex standardized systolic and diastolic BP was 126.6/78.7 mmHg for the entire group, 133.8/81.9 mmHg in individuals on antihypertensive medication, and 125.4/78.6 mmHg in those not taking antihypertensive drugs. The proportion of subjects with high BP (≥140/90 mmHg) were: 30.9% for the entire group, 40.4% in subjects taking antihypertensive drugs, and 17.9% in those not taking antihypertensive drugs. Of all participants, 33.9% were in the age range of 18-29 years and we observed higher BP levels and more frequent BP elevation in males in this age group. These data provide unique insights into the hypertension rates during the COVID-19 pandemic. Due to the associated restrictions, only limited data could be obtained for older adults. Interestingly, among young Polish participants, the rate of hypertension and the level of BP were higher in males compared to females, suggestive perhaps of a higher susceptibility of males to experience a rise in BP during specific circumstances associated with a pandemic.

Association of body mass index and long-term mortality in patients from nationwide LIPIDOGRAM 2004-2015 cohort studies: no obesity paradox?

BACKGROUND: An obesity paradox has been described in relation to adverse clinical outcomes (e.g., mortality) with lower body mass index (BMI). AIMS: We sought to evaluate the association between BMI and weight loss with long-term all-cause mortality in adult populations under the care of family physicians. METHODS: LIPIDOGRAM studies were conducted in primary care in Poland in 2004, 2006, and 2015 and enrolled a total of 45,615 patients. The LIPIDOGRAM Plus study included 1627 patients recruited in the LIPIDOGRAM 2004 and repeated measurements in 2006 edition. Patients were classified by BMI categories as underweight, normal weight, overweight and class I, II, or III (obesity). Follow-up data up to December 2021 were obtained from the Central Statistical Office. Differences in all-cause mortality were analyzed using Kaplan‒Meier and Cox regression analyses. RESULTS: Of 45,615 patients, 10,987 (24.1%) were normal weight, 320 (0.7%) were underweight, 19,134 (41.9%) were overweight, and 15,174 (33.2%) lived with obesity. Follow-up was available for 44,620 patients (97.8%, median duration 15.3 years, 61.7% females). In the crude analysis, long-term all-cause mortality was lowest for the normal-weight group (14%) compared with other categories. After adjusting for comorbidities, the highest risk of death was observed for the class III obesity and underweight categories (hazard ratio, HR 1.79, 95% CI [1.55-2.05] and HR 1.57, 95% CI [1.22-2.04]), respectively. The LIPIDOGRAM Plus analysis revealed that a decrease in body weight (by 5 and 10%) over 2 years was associated with a significantly increased risk of death during long-term follow-up-HR 1.45 (95% CI 1.05-2.02, p = 0.03) and HR 1.67 (95% CI 1.02-2.74, p < 0.001). Patients who experienced weight loss were older and more burdened with comorbidities. CONCLUSIONS: Being underweight, overweight or obese is associated with a higher mortality risk in a population of patients in primary care. Patients who lost weight were older and more burdened with cardiometabolic diseases, which may suggest unintentional weight loss, and were at higher risk of death in the long-term follow-up. In nonsmoking patients without comorbidities, the lowest mortality was observed in those with a BMI < 25 kg/m2, and no U-curve relationship was observed.

Relationships between quality of life and comprehensive geriatric assessment among seniors - a cross-sectional study in Krakow, Poland.

B a c k g r o u n d: Due to current increased life expectancy, the quality of life (QoL) of senior patients is gaining in importance. The aims of this study were: to estimate QoL in a group of patients, aged above 64 years, that is cared for by general practitioners (GPs) in Krakow, Poland, and to find relation- ships between elements of QoL and the results of comprehensive geriatric assessment (CGA) and other important medical and social factors. M e t h o d s: We designed a cross-sectional, questionnaire study among patients who attended GPs' surgeries from April 2018 to April 2019. To examine the patients, we used the Euro-Quality of Life Questionnaire (EQ-5D-5L) and eight scales forming CGA: the Activities of Daily Living, the Instrumental Activities of Daily Living, Mini-Mental State Examination, Geriatric Depression Scale, Timed Up and Go Test, Mini Nutritional Assessment, Clinical Frailty Scale and Athens Insomnia Scale. R e s u l t s: The lowest QoL was observed in dimensions of pain/discomfort and mobility, where 70% and 52% of patients, respectively, reported problems in these areas. Only 91 (21%) respondents had highest results in all five dimensions of QoL. The average score in the Visual Analogue Scale (VAS) of the EQ-5D-5L (representing self-rated health on a given day) was 62.36 ± 18.98 points. Statistically significant relationships were observed between QoL and age, physical activity and multimorbidity (in all cases p <0.001). The results of QoL were correlated with every aspect of CGA, while the strongest relationship was noticed between scores in the EQ-5D-5L VAS scale and scales assessing depression and frailty (p <0.001; r = -0.57 both).

Analysis of the impact of sex and age on the variation in the prevalence of antinuclear autoantibodies in Polish population: a nationwide observational, cross-sectional study.

The detection of antinuclear autoantibody (ANA) is dependent on many factors and varies between the populations. The aim of the study was first to assess the prevalence of ANA in the Polish adult population depending on age, sex and the cutoff threshold used for the results obtained. Second, we estimated the occurrence of individual types of ANA-staining patterns. We tested 1731 patient samples using commercially available IIFA using two cutoff thresholds of 1:100 and 1:160. We found ANA in 260 participants (15.0%), but the percentage of positive results strongly depended on the cutoff level. For a cutoff threshold 1:100, the positive population was 19.5% and for the 1:160 cutoff threshold, it was 11.7%. The most prevalent ANA-staining pattern was AC-2 Dense Fine speckled (50%), followed by AC-21 Reticular/AMA (14.38%) ANA more common in women (72%); 64% of ANA-positive patients were over 50 years of age. ANA prevalence in the Polish population is at a level observed in other highly developed countries and is more prevalent in women and elderly individuals. To reduce the number of positive results released, we suggest that Polish laboratories should set 1:160 as the cutoff threshold.

May Measurement Month 2019: an analysis of blood pressure screening results from Poland.

May Measurement Month 2019 is the third edition of a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for blood pressure (BP) screening. We present data analysis from Poland. To evaluate the potential of opportunistic BP measurements as a tool for cardiovascular disease prevention programmes. To collect new country data for further annual comparisons. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 201 sites in May 2019. BP was measured in 7072 subjects (mean age: 54 ± 15 years; 62.3% females). After multiple imputation, the age- and sex-standardized systolic BP (SBP) and diastolic BP (DBP) was 125.4/78.5 mmHg in the whole group, 133.3/82.8 mmHg in individuals on antihypertensive medication and 123.3/77.7 mmHg in those not taking antihypertensive drugs. The proportion of subjects with high BP (≥140/90 mmHg) were 41.8% in subjects taking antihypertensive drugs, and 19.6% in those not taking any antihypertensive drugs. Overall, hypertension was present in 55.4% of participants (3917 out of 7072), of whom 83.0% were aware of their diagnosis. 80.4% of hypertensives were taking antihypertensive medication. 46.7% of all hypertensives had BP controlled to target (<140/90 mmHg). Higher BP correlated with body mass index and age but not tobacco smoking. SBP but not DBP was higher in diabetic participants. These data provide evidence on the current epidemiology of hypertension and may serve as a source of information to introduce primary and secondary prevention programmes to reduce cardiovascular risk in Poland.

Is the clinical manifestation of anaphylaxis in children influenced by the trigger of reaction?

INTRODUCTION: The number of anaphylaxis diagnoses in children is rising, being still based on the clinical picture. AIM: To determine whether triggers of anaphylaxis influence its clinical characteristics in children and adolescents. MATERIAL AND METHODS: The study group included 114 children (5 months-17 years, mean age: 8.0 ±4.8 years), (66%: boys) with the episode of anaphylaxis up to 1 year back. Medical data were entered to the NORA Registry by means of a validated structured on-line questionnaire. RESULTS: Three most frequent triggers of anaphylaxis were: insect venom (47.4%), food (35.1%), drugs (5.3%), with a predominance of food (egg white, cow's milk, nuts and peanuts) in the 0-6 years age group, while insect venom (bee predominance) in the 7-17 years age group (p = 0.016). Clinical manifestations differed between food vs. venom allergic reactions and presented as gastro-intestinal (GI) (61.4%) (p = 0.004), respiratory (RS) (93.9%) (p = 0.036), and cardiovascular (CVS) (74.6%) (p = 0.022) symptoms. Among objective symptoms, vomiting was the most common symptom in the 0-2 years age group (47.1%) (p = 0.006), while hypotension in those aged 7-12 years (40%) (p = 0.010). Severity of symptoms evaluated as Mueller's grade (IV - 74.5%) and as Ring and Messmer's grade (III - 65.8%), depended on the trigger (p = 0.028, p = 0.029, respectively). Life-threatening symptoms occurred in 26 children (fall of the blood pressure - 22%, loss of consciousness - 4.4%). CONCLUSIONS: The clinical manifestation of anaphylaxis in children is both trigger and age dependent, irrespective of the gender. A typical patient with food anaphylaxis was younger, presenting predominantly GI symptoms, while a typical patient with venom anaphylaxis was older, with mostly cardiovascular symptoms.

Intervention in anaphylaxis: the experience of one paediatric centre based on NORA reports.

Introduction: Intramuscular adrenaline administration is the primary intervention in anaphylaxis. Aim: To analyse the data on intervention in children admitted due to anaphylaxis to the tertiary paediatric centre and compare them to the data from the Network for Online-Registration of Anaphylaxis. Material and methods: A validated structured on-line questionnaire was used to collect data concerning the first and second-line intervention in anaphylaxis. The study was conducted in cooperation with the European Anaphylaxis Registry. Results: The study group comprised 114 children (76 boys, 66.87%) aged 5 months-17 years with the predominance of moderate-to-severe anaphylaxis (grade III in Ring and Messmer's, and grade IV in Mueller's scale). In 103 (90.4%) children the first line of medical intervention was provided by medical staff. In the first-line intervention 39 (34.8%) children were given adrenaline. Five (4.4%) children were given the second dose of adrenaline and were admitted to the intensive care unit. In the second-line intervention adrenaline was given to 12 (15.6%) children. In one third it was at least the second reaction to the same trigger. Children treated with adrenaline were older (9.3 ±4.8 years), in comparison to those not treated (7.3 ±4.6 years, p = 0.034). Directly after the episode of anaphylaxis the children got the prescription for the adrenaline autoinjector in 35.1%, emergency training in 7.9%, and counselling on the avoidance of the anaphylaxis trigger in 30.7%. Grade III R&M reaction increased 3-fold the odds of AAI prescription (95% CI: 1.08-8.15). Conclusions: There is a strong need to continue education on proper management of anaphylaxis in children.

Emergence of linezolid-resistant Staphylococcus epidermidis in the tertiary children's hospital in Cracow, Poland.

Coagulase-negative staphylococci, ubiquitous commensals of human skin, and mucous membranes represent important pathogens for immunocompromised patients and neonates. The increasing antibiotic resistance among Staphylococcus epidermidis is an emerging problem worldwide. In particular, the linezolid-resistant S. epidermidis (LRSE) strains are observed in Europe since 2014. The aim of our study was to genetically characterize 11 LRSE isolates, recovered mostly from blood in the University Children's Hospital in Krakow, Poland, between 2015 and 2017. For identification of the isolates at the species level, we used 16S rRNA sequencing and RFLP of the saoC gene. Isolates were characterized phenotypically by determining their antimicrobial resistance patterns and using molecular methods such as PFGE, MLST, SCCmec typing, detection of the ica operon, and analysis of antimicrobial resistance determinants. All isolates were multidrug-resistant, including resistance to methicillin, and exhibited so-called PhLOPSA phenotype. In PFGE, all isolates (excluding one from a catheter) represented identical patterns, were identified as ST2, and harbored the ica operon, responsible for biofilm formation. Linezolid resistance was associated with acquisition of A157R mutation in the ribosomal protein L3 and the presence of cfr gene. All isolates revealed new SCCmec cassette element composition. Recently, pediatric patients with serious staphylococcal infections are often treated with linezolid. The increasing linezolid resistance in bacterial strains becomes a real threat for patients, and monitoring such infections combined with surveillance and infection prevention programs is very important to decrease number of linezolid-resistant staphylococcal strains.

May Measurement Month 2018: an analysis of blood pressure screening campaign results from Poland.

Hypertension remains the most important cardiovascular risk factor in Poland. May Measurement Month is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for blood pressure (BP) screening and demonstrating the potential of the opportunistic BP measurements. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in 146 sites in May 2018. Blood pressure was measured in 6450 subjects (mean age: 41 ± 15 years; 59% females). After multiple imputation, the age and sex standardized systolic and diastolic BP was 126.7/78.4 mmHg in the whole analysed group, 132.8/81.3 mmHg in subjects taking antihypertensive drugs, and 125.7/78.0 mmHg in those not taking any antihypertensive drugs. After multiple imputation, the proportions of subjects with high BP (systolic ≥140 mmHg or diastolic ≥90 mmHg or on treatment for raised BP) were 22.2% in the whole analysed group, 39.2% in subjects taking antihypertensive drugs, and 18.6% those not taking any antihypertensive drugs. Overall, hypertension was present in 32.8% of participants, among them 38.7% were not aware of the disease, 53.1% were taking antihypertensive drugs, and 32.3% had BP controlled to target (<140/90 mmHg). Blood pressure was increasing with increasing body mass index and alcohol intake. Smokers and project participants with diabetes had increased average BP. In conclusion, this project provides additional evidence for a considerable potential for further reduction of cardiovascular risk through improvement in detection and treatment of hypertension in Poland.

Effect of using cardiovascular risk scoring in routine risk assessment in primary prevention of cardiovascular disease: an overview of systematic reviews.

BACKGROUND: Our objectives were to critically appraise and summarise the current evidence for the effectiveness of using cardiovascular disease (CVD) risk scoring (total risk assessment - TRA) in routine risk assessment in primary prevention of CVD compared with standard care with regards to patients outcomes, clinical risk factor levels, medication prescribing, and adverse effects. METHODS: We carried out an overview of existing systematic reviews (SRs). Presentation of the results aligned guidelines from the PRISMA statement. The data is presented as a narrative synthesis. We searched MEDLINE (Ovid), EMBASE, CENTRAL and SCOPUS databases from January 1990 to March 2017, reviewed the reference lists of all included SRs and searched for ongoing SRs in PROSPERO database. We encompassed SRs and meta-analyses which took into account RCTs, quasi-RCTs, and observational studies investigating the effect of using CVD risk scoring. Only studies performed in a primary care setting, with adult participants free of clinical CVD were eligible. Intervention was CVD risk assessment with use of the total CVD risk scoring compared with standard care with no use of TRA . RESULTS: We identified 2157 records, we then recognised and analysed 10 relevant SRs. One SR reported statistically insignificant reduction of CVD death, when using TRA, the second SR presented meta-analysis which reported no effect on fatal and non-fatal CV events compared with conventional care (5.4% vs 5.3%; RR 1.01, 95% CI 0.95 to 1.08; I2 = 25%). Three SRs have shown that using TRA causes no adverse events. The impact of TRA on global CVD risk as well as individual risk factors is ambiguous, but a tendency towards slight reduction of blood pressure, total cholesterol and smoking levels, especially in high risk patient groups was observed. TRA had no influence on lifestyle behaviour. CONCLUSIONS: There is limited evidence, of low overall quality, suggesting a possible lack of effectiveness of TRA in reducing CVD events and mortality, as well as a clinically insignificant influence on individual risk factor levels. Using TRA does not cause harm to patients. TRIAL REGISTRATION: Systematic review protocol was registered with the International PROSPERO database - registration number CRD42016046898 .

Do we know more about hypertension in Poland after the May Measurement Month 2017?-Europe.

Elevated blood pressure (BP) is a worldwide burden, leading to over 10 million deaths yearly. May Measurement Month (MMM) is a global initiative organized by the International Society of Hypertension aimed at raising awareness of hypertension and the need for BP screening. An opportunistic cross-sectional survey of volunteers aged ≥18 was carried out in May 2017. BP measurement, the definition of hypertension and statistical analysis followed the globally approved MMM17 Study Protocol. In Poland 5834 (98.9%, Caucasian) individuals were screened. After multiple imputation, 2601 (35.3%) had hypertension. Of individuals not receiving anti-hypertensive medication, 976 (20.6%) were hypertensive. Of individuals receiving anti-hypertensive medication, 532 (49.1%) had uncontrolled BP. In the crude screened group, 81.4% declared to not receive any anti-hypertensive treatment, while the remaining 18.6% were on such medications. In overweight and obese patients both systolic and diastolic BP were significantly higher than in normal weight and underweight subjects. In addition, BP measured on Sundays was significantly lower than on Mondays. MMM17 was one of the largest recent BP screening campaigns in Poland. We found that over 1/3 of participants were hypertensive. Almost half of the treated subjects had uncontrolled BP. These results suggest that opportunistic screening can identify substantial numbers with raised BP.

Lung ultrasound in the diagnosis of neonatal respiratory failure prior to patient transport.

PURPOSE: Lung ultrasound (LUS) at the point-of-care is a new method that is increasingly used in neonatology. The aim of this study was to determine the utility of the addition of LUS prior to the interhospital transport of neonates with respiratory failure. METHODS: LUS was performed on 50 newborns with respiratory failure prior to transport to a tertiary neonatal intensive care unit. We analyzed the performance of LUS for diagnosing the cause of respiratory failure, the concordance between LUS, chest X-ray (CXR) and final clinical diagnosis, and the impact of LUS on clinical decision making before transport. RESULTS: LUS sensitivity for the diagnosis of respiratory distress syndrome was 91.3% (95%CI: 70.5-98.5%), and specificity was 92.6% (95%CI: 74.2-98.7%), whereas sensitivity and specificity of CXR were 69.6% (95%CI: 47.0-85.9%) and 81.5% (95%CI: 61.2-92.9%), respectively. For the recognition of pneumothorax (PTX) LUS had a sensitivity of 83.3% (95%CI: 36.5-99.1%) and a specificity of 100% (95%CI: 89.9-100%). For CXR, sensitivity was 16.7% (95%CI: 0.01-63.5%) and specificity was 97.7% (95%CI: 86.4-99.9%). The agreement between LUS and CXR in diagnosing the cause of respiratory failure was substantial (κ of 0.57 [95%CI: 0.40-0.74]) and the agreement between LUS and the final clinical diagnosis was very good (κ of 0.86 [95%CI: 0.74-0.98]). In 42% of the patients, a LUS examination prior to transport indicated the need for endotracheal tube repositioning or PTX decompression. CONCLUSION: LUS may be a reliable imaging technique for differentiating the causes of respiratory failure before neonatal transport. Use of LUS may optimize the care of infants during transport.

The systematic coronary risk evaluation (SCORE) for the prevention of cardiovascular diseases. Does evidence exist for its effectiveness? A systematic review.

OBJECTIVES: The SCORE model predicts the ten-year risk of cardiovascular mortality but it is still unknown whether applying the SCORE in clinical practice subsequently improves cardiovascular disease (CVD) outcomes. The objective of this study is to assess the effect of total cardiovascular risk estimation using the SCORE in preventing serious cardiovascular events in European adults without prior CVD. METHODS AND RESULTS: Data sources: eight bibliographical databases (2003 - August 2015), other internet sources and reference lists of articles were checked. This was supplemented by contact with the board members of the European Society of Cardiology (ESC) and the authors of the SCORE model. STUDY ELIGIBILITY CRITERIA: all prospective studies in any language investigating the effect of using the SCORE on the clinical outcome (CVD death, major events and adverse outcomes) in an adult population were examined. Two reviewers assessed the studies independently (titles, abstracts, full texts). After removal of duplicates, 5,256 records were screened and 14 full text papers considered. No eligible studies were identified. An extensive literature search revealed no randomized control trial or other prospective study comparing significant clinical outcomes between groups that used the SCORE and those who did not. CONCLUSIONS: The effect of using the SCORE (with or without subsequent intervention) on CVD death, all-cause mortality, major CVD events like myocardial infarction and stroke, as well as adverse outcomes, is still unknown. A cluster randomised controlled trial is warranted to evaluate the use of the SCORE on important outcomes.

Prevalence of respiratory tract infections, allergies and assessment of humoral immunity within the Malopolska region's cohort of 11- year old children born with extremely low birth weight in comparison with to their term born peers.

BACKGROUND: Children born with extremely low birth weight (ELBW) have more respiratory tract complications during childhood. Little is known about respiratory and allergy problems in ELBW children at the threshold of adolescence. MATERIALS AND METHODS: A follow-up study was conducted at the age of 11 among ELBW children (n=65) and age-matched controls (n=36). The primary outcomes in the study were the occurrence of respiratory and allergy problems and the rate of hospitalization due to respiratory complications at the age of 11 years, assessed with a questionnaire. Secondary outcome variables were serum levels of immunoglobulin classes. RESULTS: ELBW children had more respiratory tract infections (31 vs.11%, p = 0.03), but less allergies (3 vs. 22%, p < 0.01) compared with controls and had lower level of serum tIgE (geometric mean: 46.5 vs. 89.3 kU/l, p = 0.02). The risk factors for the occurrence of respiratory tract disorders in the ELBW group were: low gestational age, need for surfactant therapy and length of ventilatory support in the neonatal period. CONCLUSIONS: ELBW children have more frequent respiratory tract complications, but fewer allergies at the age of 11 years compared with children born at term. Lower respiratory tract problems decrease in ELBW children with age. Respiratory tract infections are not connected with deficiency in humoral immunity.

Does aberrant architecture of nuclear LINC complex stop muscle cell development?

The linker of nucleoskeleton and cytoskeleton (LINC) complex is a structure that spans the entire nuclear envelope (NE) and integrates the nuclear interior with the cytoskeleton. Lamin A/C together with nesprins that mainly reside along the inner nuclear membrane (INM) and outer nuclear membrane (ONM) are core components of the LINC complex. Integrity of this specific nuclear structure is critical for muscle cell maturation and function. In the present study, we analyzed the ultrastructure of the LINC complex observed in two neonates with severe hypotonia and respiratory distress. Disruption of the LINC complex manifests in a wide separation of the ONM from the INM; the loss of perinuclear space (PNS) and delayed muscle cell maturation were predominating findings. This nuclear phenomenon has never been reported and provides further support for the appearance of a neonatal form of laminopathy.

[Internet addiction among graduates of general secondary schools in Cracow and its correlation with body mass index and other health problems]. / Stopien uzaleznienia od Internetu maturzystów krakowskich liceów ogólnoksztalcacych a wskaznik masy ciala i inne problemy zdrowotne.

UNLABELLED: Studies find increasing trend among children, adolescents and young adults to spend excessive amounts of time surfing in the Internet. Another serious problem is the increasing proportion of young people who are overweight and obese. There are only few papers trying to correlate these two trends. AIM: The aims of the study were as follows: identification the extent of Internet addiction among students of Krakow's secondary schools and its correlation with BMI and other health problems. MATERIALS AND METHODS: Cross-sectional study among 200 pupils of randomly selected Krakow's high schools was conducted. Internet addiction was evaluated by using the Internet Addiction Test (IAT) by Kimberly Young. Each participant filled in an authors' questionnaire about his/her basic social and medical information. For each participant BMI was calculated. RESULTS: It was found that 7% of study group was addicted to the Internet (above 49 points in the IAT questionnaire). Internet addicts had higher BMI. The study revealed also several statistically significant relationships between the level of Internet addiction and the time spent online, BMI, back pain, headache. CONCLUSIONS: There is a modest percentage of people addicted to the Internet in the population of high school graduates, but these people often complain of back pain and headaches. BMI is higher among addicted youths. The time spent by high school graduates on online activity is far beyond the time devoted to physical activity.

Clinical validity of urinary interleukin 18 and interleukin 6 determinations in preterm newborns.

INTRODUCTION: Preterm newborns are at a particular risk of acute kidney injury (AKI) and sepsis. PURPOSE: Assessment of urinary interleukin 18 (ulL-18) and urinary interleukin 6 (ulL-6) concentrations in association with AKI and sepsis respectively in newborns hospitalized in Neonatal Intensive Care Unit (NICU). MATERIAL AND METHODS: An evaluation was carried out of the dependence of ulL-18 on neonatal birth weight (BW) and AKI as well as ulL6 on sepsis. In prospective study, the evaluation included 58 children with BW up to 2000 g. Clinical observations spanned the period between the 1st and 28th day of life. RESULTS: The mean gestational age was 30.3 Hbd, mean BW was 1361.9 g. AKI was diagnosed in 35 (60.3%), sepsis in 22 (39.7%) neonates. For median values of uIL-18 and ulL-18/mgCr, as well as for mean logarithmically transformed values of ulL-18 and ulL-18/mgCr, negative, statistically significant linear correlations were demonstrated for BW. In population, median value of ulL-18 and ulL-18/mgCr decreased respectively by 8.21 pg/ml and 84.8 pg/mgCr per each 100 g increment of BW. A negative, statistically significant linear correlation with an average strength was noted for the dependency of the duration of AKI and BW. No significant differences were observed in uIL-18 and ulL-181 mgCr values between the investigated days of AKI and reference group. There was noted a significant increase of the values of uIL-6 and uIL-6/ mgCr on day 0 of sepsis confirmed by the ROC analysis with AUROC 78% and 74%, respectively. CONCLUSIONS: ulL-18 and ulL-18/mgCr values might be a reliable marker of renal tubules maturation in newborns; ulL-18 is not a reliable marker in diagnosing AKI in neonatal population; ulL-6 and uIL-6/ mgCr concentration values measured on actual days may be regarded an early marker of sepsis; AKI duration in preterm neonates is negatively correlated with BW.

Position paper of the Polish Expert Group on the use of pitavastatin in the treatment of lipid disorders in Poland endorsed by the Polish Lipid Association.

Lipid disorders, primarily hypercholesterolemia, are the most common cardiovascular (CV) risk factor in Poland (this applies even 3/4 of people). The low-density lipoprotein cholesterol (LDL-C) serum level is the basic lipid parameter that should be measured to determine CV risk and determines the aim and target of lipid-lowering treatment (LLT). Lipid-lowering treatment improves cardiovascular prognosis and prolongs life in both primary and secondary cardiovascular prevention. Despite the availability of effective lipid-lowering drugs and solid data on their beneficial effects, the level of LDL-C control is highly insufficient. This is related, among other things, to physician inertia and patients' fear of side effects. The development of lipidology has made drugs available with a good safety profile and enabling personalisation of therapy. Pitavastatin, the third most potent lipid-lowering statin, is characterised by a lower risk of muscle complications and new cases of diabetes due to its being metabolised differently. Thus, pitavastatin is a very good therapeutic option in patients at high risk of diabetes or with existing diabetes, and in patients at cardiovascular risk. This expert opinion paper attempts at recommendation on the place and possibility of using pitavastatin in the treatment of lipid disorders.

Registered incidence of acute upper respiratory tract infections diagnosed by primary care physicians in Poland - 5-year retrospective analysis of the national health insurance database.

INTRODUCTION AND OBJECTIVE: Upper respiratory tract infection (URTIs), caused by a variety of viruses and sometimes by bacteria, represents the most common acute illness in primary health care. The aim of the study was to explore the registered incidence of URTIs in Poland in the period between 2015-2019, and its burden on the health care system. MATERIAL AND METHODS: A retrospective analysis was carried out of all medical encounters in Poland registered within the national billing database of public healthcare services. Medical services provided due to acute URTIs were classified according to the ICD-10 codes. Registered Incidence Rate (RIR) was calculated yearly, in a 100,000 population. A generalised additive model was used to calculate the Incidence Rate Ratio (IRR). RESULTS: In the analysed 5-year period, acute URTI was diagnosed in 24.3 million patients (61.7% of the whole population registered in PHC). The RIR of all acute URTIs in PHC was 50,762/100,000/year. Nearly 99% of consultations in this group of patients were provided by PHC physicians. Only 0.8% were referred to an OSC consultation and 0.4% were hospitalised. In PHC, indeterminate URTIs were most frequently diagnosed. The estimated IRR for children aged 1-4 years was 1.65 (95% CI: 1.64; 1.66, p<0.01) and for men 0.79 (95% CI: 0.79; 0.79; p<0.01). In the studied period, the number of patients consulted for acute URTI decreased slightly in PHC, but significantly in specialist services. CONCLUSIONS: The registered incidence of URTIs in Poland burdens mainly PHC physicians. Women and children aged 1-4 years are more frequent users of medical services related to URTIs. It appears that strategies for increasing patient empowerment to provide efficient self-care reducing the utilisation of PHC services are needed.
