The hero of American and Polish nations: a molecular look at Thaddeus Kosciuszko's cause of death suggests a contribution of endocarditis caused by Cutibacterium acnes infection.

The remains of the heart tissue of Thaddeus Kosciuszko have been investigated as the possible cause of disease and death of the hero of Polish and American nations. Three specimens, DNA isolated from scrappings of wax surface, from the surface of a wooden plate, and from the linen cloth that have had contact with the object were subjected to nanosequencing. From the first two, among all reads identified, only one classified as Propionibacterium acnes (synonymous current name Cutibacterium acnes), had a purported clinical significance. The observed identity between the P. acnes sequences and reference was 89-90% consistent with the hypothesis that the identified reads represent the ancient P. acnes DNA (aDNA), which underwent fragmentation and sequence changes caused by its long-time presence in the environmental conditions conducive to degradation. We present a reasonable and entirely new hypothesis that the analyzed samples could reflect the presence of the bacteria in the original Kosciuszko's heart tissue and that the process of C. acnes infection was progressing inside the organ (endocarditis), not on its surface (pericarditis) leading to rapid deterioration of health and eventually death. We again point out that normal skin and mucosal membranes commensal, a causative agent of common skin acne, may be associated with various severe organ infections posing a threat to health and life.

Safety of bronchodilator reversibility test in elderly subjects: a prospective study.

INTRODUCTION: The reversibility test measures an increase in ventilation parameters after the administration of 400 mg of a short-acting ß-agonist (SABA). It is worth noting that a typical dosage, applied as a rescue medicine for bronchospastic dyspnoea, is significantly less, i.e., 100-200 mg. AIM: To assess the effects of inhaled 400 mg fenoterol (in the bronchodilator reversibility test) on the heart rate and the development of tachyarrhythmias in subjects aged 65 and above. MATERIAL AND METHODS: A total of 53 subjects (45 women) aged 77; 68-82 (median; interquartile range) in stable clinical condition were included in the study. Data including medical history, physical examinations, blood biochemistry, chest X-ray, 12-lead electrocardiogram, 24-hour Holter ECG monitoring, bronchodilator test, and echocardiography were obtained. During the Holter ECG monitoring, the bronchodilator test using 400 mg fenoterol (Berotec pMDI) was performed. RESULTS: A slight but statistically significant (p = 0.02) increase in heart rate from 71 to 75 per min (median) was noted after the administration of fenoterol. No statistically significant differences were found in the number of extrasystolic beats of either supraventricular (p = 0.42) or ventricular origin (p = 0.50). In addition, the subjects did not show any potentially dangerous arrhythmias or significant signs of coronary artery disease. However, there was a significant increase in the number of supraventricular beats in the subjects who were not taking ß-blockers. CONCLUSIONS: The use of 400 mg fenoterol in a bronchodilator reversibility test in elderly subjects does not entail any significant cardiovascular risk.

The Relationship Between the Effectiveness of Blood Pressure Control and Telomerase Reverse Transcriptase Concentration, Adipose Tissue Hormone Concentration and Endothelium Function in Hypertensives.

BACKGROUND: This study aimed to evaluate the relationship between the effectiveness of blood pressure (BP) control and telomerase reverse transcriptase concentration (TERT), the concentration of adipose tissue hormones and endothelium function in hypertensive patients. METHODS: The study group included 94 people with arterial hypertension. Two subgroups were distinguished according to effective BP control during 24-hour ambulatory blood pressure monitoring (ABPM): Group A - effective BP control (n=49) and Group B - ineffective BP control (n=45). Telomerase reverse transcriptase concentration, blood visfatin concentration and blood adipsin concentration were determined. The function of the endothelium was measured with the flow-mediated dilatation (FMD) method. RESULTS: Telomerase reverse transcriptase concentration, blood visfatin concentration and FMD were higher in Group A compared with Group B. Ineffective BP control was an independent risk factor for lower TERT, lower blood visfatin concentration and lower FMD. Diuretics, ß-blockers and angiotensin receptor blockers were independent protective factors for lower TERT. Angiotensin-converting enzyme inhibitors (ACEI) were independent protective factors for lower blood visfatin concentration. Calcium channel blockers were independent protective factors for lower FMD. CONCLUSIONS: Ineffective BP control, assessed by ABPM, was associated with decreased TERT, worse metabolic profile of adipose tissue and impaired endothelial function in hypertensives.

Itch in Elderly People: A Cross-sectional Study.

Ageing is associated with numerous medical afflictions, including dermatological symptoms and diseases. Chronic itch (CI) in elderly people is a frequent symptom of diverse aetiology. This study assessed the prevalence and detailed clinical features of CI among 153 elderly patients hospitalized in the geriatric ward, including associations with comorbidities and pharmacotherapy. CI affected 35.3% of subjects, most commonly due to cutaneous conditions, mixed aetiology and neurological disorders (53.7%, 25.9% and 11.1% of pruritic subjects, respectively). The mean itch intensity assessed with the 4-Item Itch Questionnaire (4IIQ) was 6.6 ± 2.8 points. Viral hepatitis (p = 0.02), higher serum creatinine concentration (p = 0.02) and coexistent purpuric lesions (p = 0.002) were associated with higher 4IIQ scores. In logistic regression analysis CI correlated positively with female sex, atopic dermatitis, immobility, rheumatoid arthritis and ischaemic neurological diseases, while low-molecular-weight heparins, antipruritic drugs, allergy, rosacea and higher haemoglobin concentration had the contrary effect. CI is a frequent and interdisciplinary problem among elderly subjects, which requires a holistic clinical approach.

The analysis of the parameters of 24-hr ECG Holter monitoring in patients with blood neoplasms undergoing high-dose chemotherapy and stem cell transplantation.

BACKGROUND: Hematopoietic stem cell transplantation (HSCT) is a widely used procedure in the treatment of malignant diseases, including blood neoplasms and has increased survival in hematological diseases. The aim of the study was to analyze parameters of 24-hr ECG monitoring in patients with selected blood neoplasms in whom the procedure of hematopoietic stem cell transplantation was performed. METHODS: The study group consisted of 64 adults diagnosed with hematologic cancer qualified for HSCT with the previous high dose chemotherapy (HDC). In all patients 24-hr Holter monitoring was carried out twice. First examination took place prior to the HSCT procedure, and the second after finishing the procedure of HSCT. RESULTS: The minimal and mean heart rate (HR min and HR max) from 24-hr ECG recording was statistically significantly higher after the transplantation in comparison with the first test. The number of premature ventricular complexes (PVCs) was higher in the test after HSCT. In the second examination there was significantly higher percentage of premature ventricular complexes, incidents of tachycardia, and Mobitz type 1 second degree atrioventricular block. In regression analysis, in a group of patients with blood neoplasms after HSCT and HDC, administration of cyclophosphamide, fludarabine and total body irradiation were independent risk factors for electrocardiographic abnormalities in 24-hr Holter monitoring, that is, the increase in HR min, HR mean and PVCs. CONCLUSION: In patients with blood neoplasms undergoing HSCT more electrocardiographic abnormalities may be found after this procedure in comparison with the 24-hr Holter monitoring before transplantation.

Influence of environmental tobacco smoke on morphology and functions of cardiovascular system assessed using diagnostic imaging.

Exposure to tobacco smoke is a significant problem of environmental medicine. Tobacco smoke contains over one thousand identified chemicals including numerous toxicants. Cardiovascular system diseases are the major cause of general mortality. The recent development of diagnostic imaging provided methods which enable faster and more precise diagnosis of numerous diseases, also those of cardiovascular system. This paper reviews the most significant scientific research concerning relationship between environmental exposure to tobacco smoke and the morphology and function of cardiovascular system carried out using diagnostic imaging methods, i.e. ultrasonography, angiography, computed tomography and magnetic resonance imaging. In the forthcoming future, the studies using current diagnostic imaging methods should contribute to the reliable documentation, followed by the wide-spreading knowledge of the harmful impact of the environmental tobacco smoke exposure on the cardiovascular system.

Assessment of body surface potential mapping in diabetic patients with recognized depression.

OBJECTIVES: Parameters of body surface potential mapping (BSPM) in DM II patients are significantly different comparing with healthy non-diabetic subjects. Hypothesis that these changes are more pronounced in DM II patients with depression was tested in the present study. For this purpose, analysis of the relationship between the Int-QRST (isointegral) maps distribution and the depressive symptoms intensification, as well interrelation between depressive and diabetic symptoms were performed. MATERIAL AND METHODS: BSPM registrations were obtained from the three study groups (aged 37-52 years), namely 40 diabetic patients with clinically documented depression, 30 depressive patient without DM and 90 normal subjects. BSPM recordings were displayed in a form of the Int-QRST maps. Examination with BDI and HbA1c test were also performed in all investigated subjects. RESULTS: Isointegral QRST maps turned out to display abnormal, i.e. non-dipolar distribution. Moreover, extent of Int-QRST maps multipolarity increased in the examined diabetic patients along with DM II duration, BDI scores and HbA1c level. CONCLUSIONS: Non-dipolar distribution of Int-QRST maps, more pronounced in diabetic patients with depression, can be a specific indicator of the increased risk of severe ventricular arrhythmias occurring prior to abnormalities detectable on the standard 12-lead ECG recordings, which is of great importance especially in prevention of life-threatening arrhythmias.

Heart rate variability and heart rate turbulence in patients with hematologic malignancies subjected to high-dose chemotherapy in the course of hematopoietic stem cell transplantation.

BACKGROUND: In hematological malignancies, remissions and cures may be achieved by hematopoietic stem cell transplantation (HSCT) following high-dose chemotherapy (HDC). Cardiotoxicity of such therapy has not yet been fully elucidated. Noninvasive approaches allowing to evaluate an autonomic control of the heart function include analyses of both heart rate variability (HRV) and heart rate turbulence (HRT). METHODS: In 38 patients with hematological malignancies, 24-hour electrocardiography Holter monitoring , with HRV and HRT analysis before HSCT (A test) and after HSCT (B test), was performed. RESULTS: The 24-hour analysis of HRV demonstrated that SDNN, SDNNi, rMSSD, and pNN50 parameters were significantly lower after HSCT as compared to the results obtained before the transplantation (P < 0.05). For period of diurnal activity and for night hours, SDANN, SDNNi, rMSSD, and pNN50 were significantly lower in B test, as compared to the results of A test (P < 0.05). The analysis of HRT demonstrated that turbulence onset parameter was significantly higher, and turbulence slope parameter was significantly lower in B test, as compared to A test (P < 0.05). The multifactorial stepwise backward regression analysis indicated that administration of cyclophosphamide and carmustine and higher concentrations of blood cholesterol represented risk factors for decreased HRV. Cyclophosphamide and higher triglyceride levels represented independent risk factors for decreased HRT. CONCLUSIONS: In patients with hematopoietic malignancies treated with HSCT, decreased HRV and HRT were observed after chemotherapy and stem cells administration.

[Fatty liver as a risk factor for cardiovascular diseases: retrospective analysis of data from patients of the Geriatrics Clinic of University Clinical Hospital in Wroclaw]. / Stluszczenie watroby jako czynnik ryzyka chorób sercowo-naczyniowych: analiza retrospektywna danych pacjentów Kliniki Geriatrii Uniwersyteckiego Szpitala Klinicznego we Wroclawiu.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is currently the most common liver disorder affecting about 25% of the global population. The causes of its development include poor diet, low physical activity, overweight, obesity, older age, diabetes, and lipid disorders. Non-alcoholic fatty liver disease is identified by some researchers as a hepatic manifestation of metabolic syndrome. It has been observed that patients with NAFLD have an increased risk of cardiovascular events, as well as a higher number of deaths from myocardial infarction compared to the general population. MATERIAL AND METHODS: A retrospective analysis was conducted on the data of 237 patients diagnosed with hepatic steatosis, treated in the Department of Geriatrics at the University Clinical Hospital in Wroclaw from 2019 to 2022, focusing on coexisting overweight, obesity, and concomitant diseases. Laboratory results and the degree of left ventricular muscle hypertrophy were analyzed. Parameters assessed by echocardiography, including interventricular septal thickness in diastole (IVSd), left ventricular posterior wall thickness in diastole (LVPWd), and IVSd + LVPWd/2, were used to evaluate left ventricular hypertrophy. RESULTS: Data from 237 patients were analyzed: 79 men (age: 77.2±7.1 years) and 158 women (age: 78.4±7.7 years). Body mass index (BMI) values for men and women were 30.5±5.0 kg/m² and 31.9±5.6 kg/m², respectively. There was a positive correlation between BMI and the degree of left ventricular hypertrophy for the parameters IVSd (ρ = 0.36, p < 0.001), LVPWd (ρ = 0.36, p < 0.001), and IVSd + LVPWd/2 (ρ = 0.38, p < 0.001). CONCLUSIONS: The study demonstrated a moderate positive correlation between BMI and the degree of left ventricular hypertrophy in patients diagnosed with hepatic steatosis. These findings indicate the necessity of actively searching for cardiovascular risk factors, including the evaluation of echocardiographic parameters in patients with NAFLD.

Erectile Dysfunction as an Obesity-Related Condition in Elderly Men with Coronary Artery Disease.

Background: This cross-sectional study aimed to investigate the prevalence of erectile dysfunction (ED) in elderly men with overweight or obesity and coronary artery disease. Methods: Patients recruited in cardiac rehabilitation centers post-myocardial infarction provided demographic and anthropomorphic data. ED was assessed using the abbreviated International Index of Erectile Function 5 (IIEF-5) Questionnaire. Results: The study included 661 men with a mean age of 67.3 ± 5.57 years, a mean BMI of 27.9 ± 3.6 m/kg2, and a mean waist circumference of 98.9 ± 10.23 cm. Over 90% of men experienced ED, with similar proportions across BMI categories. The development of ED in men with a waist circumference of ≥100 cm had 3.74 times higher odds (OR 3.74; 95% CI: 1.0-13.7; p = 0.04) than in men with a waist circumference of <100 cm. Men with obesity and moderate-to-severe and severe ED were older compared to those without these disorders (67.1 ± 5.29 vs. 65.3 ± 4.35; p = 0.23). Conclusions: The prevalence of ED in men with coronary artery disease surpasses 90%. An increased body weight raises the risk of ED, with waist circumference proving to be a more reliable predictor of this risk compared to BMI. Physicians are encouraged to screen elderly patients with cardiovascular disease for ED and address obesity to enhance overall health.

Elderly Patients and Insect Venom Allergy: Are the Clinical Pictures and Immunological Parameters of Venom Allergy Age-Dependent?

Insect venom is one of the most common triggers of anaphylaxis in the elderly population. Venom immunotherapy (VIT) remains the only treatment for Hymenoptera venom allergy (HVA). However, little is known about the differences in indication for VIT in the group of patients aged 60 years and older. The objective of this study was to assess the clinical and diagnostic differences of HVA in elderly patients. The study compared data from patients aged ≥ 60 (N = 132) to data from patients aged from 11 to 60 years (N = 750) in terms of HVA severity, comorbidities, and immunological parameters, namely, intradermal testing (IDT), specific IgE (sIgE) levels against extracts and major allergenic molecules, and serum tryptase level (sBT). The severity of systemic HVA (I-IV Müller scale) did not differ between adults and seniors. However, the severity of cardiovascular reactions (IV) increased with age, while the frequency of respiratory reactions (III) decreased. No differences were found in the immunological parameters of sensitization IDT, venom-specific IgE concentrations, or sIgE against Api m 1, 2, 4, 5, and 10 between patients below and above 60 or 65 years of age. Differences were noted for sIgE against Ves v1 and Ves v5; they were higher and lower, respectively, in seniors. In the seniors group, sBT levels were higher. Elevated tryptase levels, along with the aging process, can represent a risk factor within this age category. Nevertheless, advanced age does not influence the immunological parameters of immediate HVA reactions, nor does it impact the diagnosis of HVA.

Identification of Factors Affecting the Increased Percentage of CGA Recommendations among Patients on Geriatric Ward.

In Poland, the elderly population is noticeably increasing every year. Therefore, the current healthcare system has to rise to the challenge of treatment and prevention strategies targeting elderly persons. Based on the Vulnerable Elders Survey (VES-13 scale), consisting of international and validated scales, we put effort into identifying the factors affecting the increased percentage of CGA (Comprehensive Geriatric Assessment) recommendations by healthcare system physicians. The study group involved 78 patients from the Department of Geriatrics, Wroclaw Medical University, Poland, aged 60-91 (median Me = 81 years old). Of the studied patients, 51 were recommended for CGA (51/78; 64.6%). A statistically significant association was observed between CGA recommendation and age (p < 0.001); the likelihood of a CGA recommendation increased with age. Furthermore, the increased CGA recommendation was observed among geriatric patients with: (a) frailty syndrome (OR = 11.2, CI95% 2.88-43.5, p < 0.001), (b) high risk of malnutrition or malnutrition (OR = 3.87; CI95%, 1.00-14.9, p = 0.04), (c) low mental status (OR = 3.32, CI95% 1.22-9.09, p = 0.029), (d) low ability to perform basic daily duties (according to ADL scale-OR = 12.6, CI95% 1.57-101, p = 0.004 and IADL scale-OR = 4.71, CI95% 1.72-12.9, p = 0.003), and (e) fall risk (OR = 15.0, CI95% 4.67-48.3, p < 0.001). Moreover, homocysteine levels increased with age (p = 0.003) and decreased with sleep duration (p = 0.043). Taken together, all these factors seem to be important when implementing treatment programs adjusted to the individual geriatric patient.

Diet Quality Variation among Polish Older Adults: Association with Selected Metabolic Diseases, Demographic Characteristics and Socioeconomic Status.

A lot of civilization diseases are related to a low-quality diet, which is often determined by environmental factors. The aim of the present study was to assess the relationship between the quality of diet and the selected metabolic diseases, as well as demographic characteristics and socioeconomic status among Polish seniors. The study was conducted on the basis of the KomPAN questionnaire (Questionnaire for Dietary Views and Habits). The research sample was chosen arbitrarily. In addition, in order to diversify the research sample, the use of the snowball method was used. The study was conducted from June to September 2019 in a group of 437 people aged 60 or more years in two regions of Poland. Two diet quality indices with a potentially beneficial (pHDI-10) and adverse impact on health (pHDI-14) were selected based on data on the frequency of consumption of 24 food groups using the KomPAN questionnaire data development procedure. Based on the intensities (low, moderate, high) and combinations of these indices, three diet quality index profiles were developed with potentially different influences on health: lower (lowest), middle (intermediate) and upper (highest). Logistic regression was used to evaluate the relationship between diet quality indices, some metabolic diseases (obesity, arterial hypertension, diabetes type 2), demographic characteristics (gender, age, place of residence), and socioeconomic status (low, moderate, high). It was shown that in the examined seniors with selected metabolic diseases, the higher quality diet was more common among women, urban inhabitants and subjects with higher socioeconomic status. In turn, among the elderly with obesity, a high-quality diet was observed more often in people aged 60-74 years and those with type II diabetes at ages 75 years or more. The relationships between diet quality, demographic characteristics and socioeconomic status were demonstrated, but it was not possible to obtain unambiguous results on the relationship of these variables with the occurrence of metabolic diseases. Further extended studies should assess the importance of diet quality in reducing the risk of metabolic diseases in the elderly, taking into account the variability resulting from the environmental characteristics of the study population.

What Do We Know about Nociplastic Pain?

Nociplastic pain is a recently distinguished type of pain, distinct from neuropathic and nociceptive pain, and is well described in the literature. It is often mistaken for central sensitization. Pathophysiology has not been clearly established with regard to alteration of the concentration of spinal fluid elements, the structure of the white and gray matter of the brain, and psychological aspects. Many different diagnostic tools, i.e., the painDETECT and Douleur Neuropathique 4 questionnaires, have been developed to diagnose neuropathic pain, but they can also be applied for nociplastic pain; however, more standardized instruments are still needed in order to assess its occurrence and clinical presentation. Numerous studies have shown that nociplastic pain is present in many different diseases such as fibromyalgia, complex regional pain syndrome type 1, and irritable bowel syndrome. Current pharmacological and nonpharmacological treatments for nociceptive and neuropathic pain are not entirely suitable for treating nociplastic pain. There is an ongoing effort to establish the most efficient way to manage it. The significance of this field has led to several clinical trials being carried out in a short time. The aim of this narrative review was to discuss the currently available evidence on pathophysiology, associated diseases, treatment possibilities, and clinical trials. It is important that physicians widely discuss and acknowledge this relatively new concept in order to provide optimized pain control for patients.

Impact of Internet Addiction, Social Media Use and Online Pornography on the Male Sexual Function in Times of the COVID-19 Pandemic.

Over recent decades, the use of the Internet has dramatically increased, both for professional purposes and entertainment. We investigated the link between social media use, video games, dating apps, and pornography on men's sexual health, which makes life easier, but also carries potential threats. Online surveys including The International Index of Erectile Function (IIEF) and Bergen Social Media Addiction Scale questionnaires were spread to young, sexually active men. We asked about demographics, sexual activity, and the use of social media, video games, dating apps, and pornography. We enrolled 702 men aged 18 to 60 years (mean 24.06 ± 5.70). In general, 1.6% of men were exposed to social media addiction. Social media addiction had a negative impact on IIEF scores, while pornography in general had no impact on men's sexual health. However, more extensive use of pornography was correlated with lower IIEF scores. A negative impact of dating apps use on the IIEF score was also found but the correlation was weak (p = 0.049). No correlation was found between playing games and IIEF. We conclude that social media addiction negatively affected men's sexual functioning during the COVID-19 pandemic. The development of strategies for the safe use of the Internet and dissemination of this knowledge through social media campaigns can help young people to recognize the first symptoms of social media addiction.

Association between Leukocyte Cell-Derived Chemotaxin 2 and Metabolic and Renal Diseases in a Geriatric Population: A Pilot Study.

LECT2 is not a routine diagnostic marker for any disease, but it has been associated with many pathologies, including systemic amyloidosis, rheumatoid arthritis, diabetes, atherosclerosis, and metabolic syndrome. With human aortic sections (n = 22) and sera from geriatric subjects (n = 79), we analyzed the relationships that could be observed between this protein and other parameters related to metabolic diseases. As a result, we observed a relatively high (r~0.8, p < 0.05) positive correlation between SRA and LECT2 and a negative correlation between EGFR and LECT2 (r~-0.4, p < 0.05). We observed LECT2 expression in macrophages, myocytes, and other aortic cells, with a tendency to be overexpressed in developed atherosclerotic plaques. We conclude that LECT2 exerts its chemotactic effects not only as a protein synthesized in the liver and secreted and circulating in the blood but also as a locally expressed protein within atherosclerotic plaque development. The LECT2-EGFR correlation suggests an association of this protein with loss of normal renal function. This fact can be associated with LECT2 amyloidosis, although it should be verified whether in the geriatric population there is indeed a widespread accumulation of LECT2 with the progression of aging or whether it is rather a marker of general deterioration of renal function.

Low Exercise Tolerance as a Marker of Erectile Dysfunction and Depression among Post-Myocardial Infarction Men.

Evidence has grown recently on the correlation between lifestyle and physical activity, and their impact on the functioning of the entire organism. In addition, a decrease in physical efficiency may be an indicator of the early diagnosis of systemic diseases. The aim of this study was to determine whether there is a relationship between exercise tolerance and possible erectile dysfunction or mental disorders. A cross-sectional study was conducted among 254 men in 4 cardiac rehabilitation centers in Poland using the standardized International Index of Erectile Function 5 (IIEF-5) and Beck Depression Inventory (BDI) questionnaires. Erectile dysfunction was directly proportional to the metabolic equivalent of the task (MET) variable. An increase in exercise tolerance by 1 point was associated with an increase in the IIEF-5 score by 1.62 points, indicating a reduction in the severity of erectile dysfunction. The 1-point increase in MET was associated with a 1.8-point decrease in BDI, indicating that an increase in exercise tolerance is associated with a decrease in the severity of depressive disorders. Increasing the tolerance of physical effort has a beneficial effect not only on the general well-being, but also on the sexual and mental health of men. An increase in exercise tolerance is associated with a reduction in the incidence of erectile dysfunction. On the other hand, in patients with depressive disorders, the improvement of exercise tolerance reduces the intensity of depression symptoms. Exercise tolerance can be an early and simple marker at the onset of erectile dysfunction or mood disorders.

Heart ventricular activation in VAT difference maps from children with chronic kidney disease.

Children with chronic kidney disease (CKD) are affected by cardiovascular complications, including disturbances in the intraventricular conduction system. Body surface potential mapping (BSPM) is a non-invasive method of assessing the cardioelectrical field. Our aim was to investigate conduction disturbances in young CKD patients using ventricular activation time (VAT) maps. Our study comprised 22 CKD children (mean age: 13.1 ± 2.5 years) treated conservatively and 29 control patients. For each child 12-lead electrocardiogram (ECG) readings were taken, and blood pressure and serum concentrations of iPTH, Pi, t-Ca, creatinine, Fe(+3), ferritin, and Hb, as well as eGFR were measured. All children underwent registration in the 87-lead BSPM system, and group-mean VAT maps and a difference map, which presents statistically significant differences between the groups, were created. The VAT map distribution in CKD patients revealed abnormalities specific to left anterior fascicle block. The difference map displays the areas of intergroup VAT changes, which are of discriminative value in detecting intraventricular conduction disturbances. Intraventricular conduction impairments in the left bundle branch may occur in children with CKD. BSPM enables conduction disturbances in CKD children to be detected earlier than using 12-lead ECG. The difference map derived from the group-mean isochrone maps precisely localizes the sites of disturbed conduction in the heart intraventricular conduction system.

Salivary Melatonin Changes in Oncological Patients: A Systematic Review.

Melatonin is known as a regulator of circadian sleep and waking rhythm. This hormone secreted by the pineal gland also has protective, oncostatic, and antioxidant properties. This systematic review was designed to answer the question "Is there a relationship between salivary melatonin changes and oncological diseases?". Following the inclusion and exclusion criteria, ten studies were included, according to PRISMA statement guidelines. In all included studies, the diagnostic material was unstimulated whole saliva, in which the melatonin changes were determined by different laboratory methods. Most studies concerned changes in melatonin levels in patients with brain tumours due to a direct effect on the circadian rhythm centres. Other studies focused on disorders of melatonin secretion and its inclusion as a diagnostic marker in patients with prostate cancer and oral squamous cell carcinoma. The association between melatonin changes and sleep quality and chronotype in patients with newly diagnosed lung cancer and lymphoma survivors was also investigated. In conclusion, our systematic review may suggest trends for melatonin secretion alterations in oncological patients. However, due to the significant heterogeneity of the included reports, it is not possible to clearly determine a link between changes in salivary melatonin levels and the oncological diagnosis.

Sociodemographic and Health-Related Factors Influencing Drug Intake among the Elderly Population.

Excessive drugs intake among the elderly population, including self-medication, constitutes an important public health problem. Polypharmacy may lead to numerous adverse health effects, which become more prevalent when combined with biological changes in seniors. In this cross-sectional study, 500 Polish adults aged ≥60 years (M = 67.9 ± 4.2) were asked to complete a questionnaire via telephone calls, allowing us to identify sociodemographic and health-related factors influencing the daily medications consumption. Our findings revealed that all of the participants were receiving medications; 60.2% of them receive at least 1 to 3 drugs per day (301/500). The most commonly used medications included antihypertensive drugs and analgesics (51.0% and 46.0%, respectively). Taking into account clinical conditions, independent predictors of receiving over 3 medications per day turned out to be (1) coronary artery disease (OR = 6.77; CI 95%, 2.86-16.1), (2) diabetes (OR = 3.23, CI 95%, 1.75-5.95), (3) asthma (OR = 4.87, CI 95%, 2.13-11.1), (4) heart failure (OR = 3.38, CI 95%, 1.59-7.19) and (5) gastroesophageal reflux disease (OR = 1.93, CI 95%, 1.03-3.62). Participants suffering from depression were more likely to take drugs for hypertension (OR = 1.70, CI 95%, 1.04-2.78), while those with anxiety and social loneliness took more painkillers (OR = 2.59, CI 95%, 1.58-4.26 and OR = 2.08, CI 95%, 1.38-3.13, respectively). The most significant sociodemographic factors increasing the drugs intake among the population included in our study were high body mass and subsequent increased BMI values (OR = 2.68, CI 95%, 1.50-4.77). Furthermore, living in a city with over 400,000 inhabitants increased the likelihood of taking antidepressants (OR = 2.18, CI 95%, 1.20-3.94). Our study revealed factors increasing the risk of excessive medications intake and hence, increased susceptibility to some iatrogenic diseases among the elderly population. These factors should be considered by primary care physicians while prescribing appropriate drugs to elderly patients.
