Pharmacotherapy of patients with benign prostate enlargement and storage symptoms in everyday clinical practice.

OBJECTIVE: Storage symptoms significantly deteriorate the quality of life in men with benign prostate enlargement (BPE). Muscarinic receptor antagonists (MRAs) and ß3-adrenergic receptors agonists alone, or in combination with selective α1-alpha-antagonists, are considered the most effective medicines relieving storage symptoms. The aim of this study was to analyze the pharmacotherapy of storage symptoms in men with BPE, and their compliance with the European Association of Urology (EAU) guidelines. PATIENTS AND METHODS: The survey was conducted in 2018 by 261 urologists among 24,613 men with lower urinary tract symptoms (LUTS) and BPE treated pharmacologically. Data concerning recent severity of non-neurological LUTS, storage symptoms and pharmacotherapy were collected. RESULTS: Storage symptoms were reported by 12,356 patients (50.2%) with BPE, more frequently nocturia (75.8%), than urinary urgency (57.8%) and frequency (44.3%). Patients with storage symptoms were more frequently prescribed with MRAs and mirabegron (43.1% vs. 5.0% and 2.4% vs. 0.3%, respectively; p<0.001). Of note, 54.5% of patients with storage symptoms were treated neither with MRAs, nor ß3-adrenergic receptors agonists. In the subgroup with storage symptoms, the increasing severity of LUTS accounted for more frequent prescription of MRA (2.1% vs.  29.1% vs. 42.8% in patients with mild, moderate, and severe LUTS, respectively). Decision tree analysis revealed that patients with urinary urgency and urinary frequency, as well as younger ones with urinary urgency but without urinary frequency, were more frequently prescribed with MRAs. CONCLUSIONS: Urinary urgency and frequency are associated with increased utilization of MRAs in men with BPE in everyday clinical practice. The attitude of Polish urologists toward management of persistent storage symptoms in BPE patients is in line with the EAU guidelines.

Increasing the dosage of pregabalin in patients with focal epilepsy decreases the frequency of seizures and ameliorates symptoms of anxiety, depression and insomnia.

OBJECTIVE: The effectiveness of the treatment depends on the adequate dosage of medications. In clinical practice, drugs are often used at doses that are too low, which results in suboptimal levels of clinical improvement. The aim of the study was to evaluate the effects of increasing the dose of previously taken pregabalin in a group of patients with focal epilepsy and generalized anxiety disorder (GAD). PATIENTS AND METHODS: This open study involved 993 patients (46 ± 14 years old) suffering from epilepsy with focal seizures and concomitant GAD treated with pregabalin add-on therapy. The severity of anxiety was assessed with GAD-7 Scale. The number of epileptic seizures was monitored before and after the increase of the pregabalin dose. RESULTS: On the initial visit, the mean daily dose of pregabalin was 159 ± 82 mg. During the study period (nine months) the mean dose was increased to 327 ± 163 mg. After nine months, based on the intention-to-treat analysis, 27.1% (N = 253) of the subjects experienced seizure resolution, and 57.8% (N = 539) reduction in seizure frequency by at least 50%. At the beginning of the study, despite pregabalin administration, 60.7% of patients were above the diagnostic threshold for GAD diagnosis. The add-on therapy resulted in the improvement of the depressive and anxiety symptoms, and insomnia, greater in those that experienced seizure resolution or reduction in their frequency. CONCLUSIONS: (1) Patients with focal epilepsy with concomitant anxiety disorder experience reduction in seizure frequency, improvement of anxiety, depressive symptoms and insomnia using PGB as an add-on therapy. (2) Our data suggest that pregabalin as an add-on treatment is a reasonable choice for patients with focal epilepsy who have concomitant symptoms of an anxiety disorder.

Prediction of detrusor underactivity based on non-invasive functional tests and clinical data in patients with symptoms of bladder outlet obstruction.

OBJECTIVE: Detrusor underactivity (DU) is a common but relatively under-researched bladder dysfunction. Recently, there has been renewed interest in this topic. The aim of the study was to develop a decision-making algorithm to predict the impaired detrusor contractility in patients with LUTS (lower urinary tract symptoms). PATIENTS AND METHODS: A retrospective analysis covered 96 consecutive patients (aged 63 ± 8 years) treated pharmacologically for 50 ± 37 months due to LUTS (persisting for 64 ± 41 months). Functional tests included uroflowmetry and flow cystometry. RESULTS: Weakened detrusor functioning was detected in 58 (60.4%) patients. Decision-making algorithm that included uroflowmetry, flow cystometry and clinical data, was showed to allow to diagnose impaired detrusor function with accuracy of 73% (95% CI - confidence interval: 61-83%) and specificity of 76% (95% CI: 54-90%). The positive predictive value of the classification tree graph is equal to 90% (95% CI: 78 -96%) and the negative predictive value is 50% (95% CI: 34-66%). The weakened detrusor function was more frequent in patients with: time to reach maximum flow rate higher than 13.5 s; time to reach maximum flow rate lower than 13.5 s and mean flow ratio higher than 4.5 ml/s, but time of flow longer than 44.5 s; time to reach maximum flow rate lower than 13.5 s and mean flow ratio lower than 4.5 ml/s, but time of flow longer than 52.5 s. CONCLUSIONS: The results of the uroflowmetry can be used to predict the impaired detrusor contractility in patients with LUTS.

Influence of Sociodemographic, Behavioral and Other Health-Related Factors on Healthy Ageing Based on Three Operative Definitions.

OBJECTIVES: Healthy ageing (HA) is a key concept and highly desirable phenomenon in every ageing and already old societies. The aim of our study was to evaluate the influence of socio-economic conditions as well as life-style and other health-related factors on the WHO definition of HA. DESIGN, SETTING, PARTICIPANTS: The study used cross-sectional data of the PolSenior Project - nationwide research evaluating different aspects of ageing in Poland - which included 4'653 respondents aged 65 years and over. MEASUREMENTS: Data were collected by trained interviewers in respondents' homes. Three definitions of HA including or not the participants' chronic conditions were analyzed. RESULTS: The prevalence of HA appeared as high as 17.6% if none or 1 chronic disease was present and 42.8% if no information about chronic diseases was taken into account. The association between known health predictors (age, marital status, education, income) and HA was observed. Moreover, HA appeared in relation with indicators of physical functioning and lifestyle. There was a strong concordance between HA and the fair self-rated health (OR = 1.87; 1.99, and 2.74 for the 1st, 2nd and 3rd definitions, respectively) and opposite relation with self-reported need for help (OR = 0.15; 0.15; and 0.13, respectively). CONCLUSIONS: The HA definition based on no functional activity limitations, no cognitive impairment, no depressive symptoms, no more than one disease and being socially active seems to be a useful approach of HA.

Atrial fibrillation independently linked with depression in community-dwelling older population. Results from the nationwide PolSenior project.

BACKGROUND: Depression is a frequently observed comorbid condition in patients with cardiovascular diseases. In contrast to coronary heart disease and heart failure there is a limited amount of published data concerning the increased prevalence of depression among patients with atrial fibrillation (AF). Therefore, we decided to assess the prevalence of depression in Polish community-dwelling older patients with a history of AF. METHODS: The data were collected as part of the nationwide PolSenior project (2007-2012). Out of 4979 individuals (age range 65-104 years), data on self-reported history of AF were available for 4677 (93.9%). Finally, 4049 participants without suspected moderate or severe dementia in Mini Mental State Examination test were assessed with the 15-item Geriatric Depression Scale (GDS), and a score of 6 points and more was regarded as suspected depression. RESULTS: Mean age (±SD) of the study population was 78.1 (±8.3) years; 52% were males. The history of AF was reported by 788 (19.5%) subjects. In the univariate analysis a self-reported AF history was associated with 42% increase of suspected depression (41% vs 29%; P < 0.001). In multivariate logistic regression AF remained an independent predictor of depression (OR = 1.69; 95%CI: 1.43-2.00), stronger than heart failure, diabetes or coronary heart disease. CONCLUSIONS: In community-dwelling geriatric Polish population AF is associated with higher prevalence of depression. This association is independent from the demographic factors, disabilities and comorbidities (including history of stroke).

Relationship Between Individual Components of the Extended-Criteria Donor Definition and the First Post-transplant Kidney Graft Resistance Index, Measured by Doppler Sonography.

BACKGROUND: Despite an increasing utilization of kidneys procured from expanded-criteria donors, little is known about the effects of particular expanded-criteria donors definition components, that is, hypertension, increased creatinine prior to procurement, and cerebrovascular cause of death on the kidney graft Doppler parameters measured shortly after transplantation, whose increased values are associated with unfavorable outcomes. Hence, we analyzed the relationship between expanded-criteria donors components and resistance index values measured within 2 to 3 days post-transplant. MATERIAL AND METHODS: The initial post-transplant resistance index value was measured in 676 consecutive successful first cadaveric kidney graft recipients without delayed graft function or early acute rejection episode. We analyzed resistance index values in 460 patients transplanted with organs from donors <50 years and in 216 recipients with organs from donors >50 years old. RESULTS: In general, expanded-criteria donors status did not influence the initial resistance index values in the whole study group. Unexpectedly, in older donor groups, both the occurrence of donor hypertension and cerebrovascular cause of death resulted in significantly lower resistance index values in kidney graft recipients (0.73 ± 0.10 vs 0.76 ± 0.11 in the non-hypertension group, P = .013 and 0.74 ± 0.11 vs 0.78 ± 0.10 in the non-cerebrovascular cause of death group, P = .015, respectively). In the Cox proportional regression model for graft survival, cerebrovascular cause of death was increasing the risk of graft loss by 55%, while recipient's age had the opposite effect, decreasing the risk of graft loss by 2% per year. CONCLUSIONS: Regardless of the limited influence of expanded-criteria donor status on first post-transplant resistance index value, the long-term observation shows moderate but significantly worse kidney graft survival, mostly as a result of the cerebrovascular cause of donor's death.

No Significant Influence of Reduced Initial Tacrolimus Dose on Risk of Underdosing and Early Graft Function in Older and Overweight Kidney Transplant Recipients.

BACKGROUND: Nowadays, a reduced initial daily dose of tacrolimus (Tac) (0.1-0.15 mg/kg) is recommended for the majority of kidney transplant recipients (KTRs). The aim of the study was to analyze the safety of such a regimen, including the risk of first inadequately low Tac blood level, acute rejection (AR) occurrence, or early graft dysfunction. METHODS: In 2011, we introduced a modified (0.1-0.15 mg/kg/d) initial Tac dosing regimen in older (>55 years) and/or overweight KTRs. To assure the safety of this protocol, we monitored the risk of inadequately low blood Tac level (<6 ng/mL) and incidence of AR or delayed graft function (DGF). The historical cohort with the higher Tac dosing regimen (0.2 mg/kg/d, n = 208) served as a control group. RESULTS: The mean Tac daily dose in 78 KTRs (group with reduced dosing) was 0.133 (95% confidence interval [CI], 0.130-0.136) mg/kg and was significantly lower than the standard, previously prescribed dose of 0.195 (95% CI, 0.194-0.197) mg/kg. Of note, induction therapy was employed twice more often in the reduced Tac dosing group. The dose reduction resulted in a slight, nonsignificant decrease in first Tac trough level. The percentages of patients with first Tac troughs <6 ng/mL (5.1% vs 4.8%), AR (6.4% vs 5.8%), and DGF (25.6% vs 31.2%) were similar in the reduced and standard dosing groups. CONCLUSION: The currently recommended reduction in Tac initial dosing does not increase the risk of inadequate immunosuppression and does not affect the early graft function. Regardless of Tac dose reduction, there is still a substantial risk of Tac overdosing in older or overweight KTRs.

Influence of Polypharmacy on the Quality of Life in Stable Kidney Transplant Recipients.

BACKGROUND: Kidney transplant recipients are frequently treated for other medical conditions and experience polypharmacy. The aim of our study was to evaluate quality of life in relation to medicines' burden in these patients. METHODS: We studied 136 unselected patients with mean post-transplant time of 7.2 ± 4.6 years. Quality of life was evaluated using a validated Polish version of the Kidney Disease Quality of Life-Short Form questionnaire. Data concerning the type (generic name) and number of currently prescribed medications were collected by interview survey. The participants were divided into 3 groups: group 1, patients with a maximum of 4 different medications (n = 37); group 2, patients with 4 to 9 medications (n = 76); and group 3, patients receiving at least 10 different medications (n = 23). RESULTS: The number of medicines taken regularly ranged from 2 to 16. Patients with ≥10 drugs had the highest body mass index and lowest estimated glomerular filtration rate. Patients treated with ≥10 drugs, compared to patients from the 2 other groups, had presented lower subscales results concerning the physical functioning (65.9 vs 84.5 in group 1 and 83.4 in group 2, P < .001 for both comparisons), pain (57.2 vs 82.7 and 76.5, respectively, P < .001 for both), social function (66.8 vs 82.1 and 80.4, respectively, P = .04 for both), and energy/fatigue (54.8 vs 67.7, P = .03 and 65.4, P < .05). Multivariate regression analysis revealed that the number of drugs independently influenced physical functioning, pain, and social function subscales. CONCLUSIONS: Polypharmacy is associated with lower quality of life in patients after successful kidney transplantation. The negative impact of polypharmacy is particularly seen regarding physical functioning and pain severity.

Prevalence of anemia in relation to socio-economic factors in elderly Polish population: the results of PolSenior study.

Anemia is an independent risk factor for functional decline and mortality among older adults. Since mild anemia in older people is often under-diagnosed and ignored, its prevalence needs precise determination and recognition of predisposing factors. None of the previous studies based on the data obtained from the representative elderly population identified the influence of socio-economic factors on the prevalence of anemia. PolSenior was a cross-sectional population-based study performed on the nationally representative sample of Polish seniors. Complete blood count was assessed in 4003 respondents aged 65 years or above (1910 women) divided into six five-year cohorts and a reference group of 622 people aged 55 - 59 years (333 women). Anemia was defined based on the WHO criteria: Hb < 12.0 g/dL in women and Hb < 13.0 g/dL in men. The following socio-economic factors were evaluated through the multiple logistic regression analysis: education level, marital status, place of residence, living arrangements and self-reported poverty. The prevalence of anemia in older persons standardized for the population was 10.8% (17.4% of the study group) and was more frequent in men than in women (20.8% versus 13.6%). The frequency of anemia progressed with age from 5.3% in the youngest to 37.7% in the oldest cohort, and the progression was higher in men. The multiple logistic regression analysis revealed the link between anemia and age in both genders, as well as unmarried status and urban dwelling in men. When age was not taken into account, logistic regression showed the link between anemia and unmarried status, urban place of residence (both genders), and low level of education (women only). Among seniors, those poorly educated, unmarried and city inhabitants require intense screening for anemia.

Components of metabolic syndrome in relation to plasma levels of retinol binding protein 4 (RBP4) in a cohort of people aged 65 years and older.

PURPOSE: Elevated plasma concentration of retinol binding protein 4 (RBP4) has recently emerged as a potential risk factor as a component of developing metabolic syndrome (MS). Therefore, this study aimed to analyse the relationship between components of MS and concentrations of plasma RBP4 in a population of subjects 65 years and older. METHODS: The study sample consisted of 3038 (1591 male) participants of the PolSenior study, aged 65 years and older. Serum lipid profile, concentrations of RBP4, glucose, insulin, C-reactive protein, IL-6, and activity of aminotransferases were measured. Nutritional status (BMI/waist circumference) and treatment with statins and fibrates were evaluated. Glomerular filtration rate (eGFR), de Ritis ratio, and fatty liver index (FLI), as well as HOMA-IR were calculated. RESULTS: Our study revealed a strong relationship between components of MS and RBP4 in both sexes: plasma RBP4 levels were increased in men by at least 3×, and in women by at least 4×. Hypertriglyceridemia was most strongly associated with elevated plasma RBP4 levels. Multivariate, sex-adjusted regression analysis demonstrated that chronic kidney disease [OR 1.86 (95% CI 1.78-1.94)], hypertriglyceridemia [OR 1.52 (1.24-1.87)], hypertension [OR 1.15 (1.12-1.19)], low serum HDL cholesterol [OR 0.94 (0.92-0.97)], and age > 80 years [OR 0.86 (0.81-0.90)] were each independently associated with RBP4 concentration (all p < 0.001). CONCLUSIONS: In Caucasians 65 years and older, RBP4 serum levels are associated with a number of components of MS, independent of sex and kidney function. Hypertriglyceridemia as a component of MS is most significantly related to RBP4 concentration.

Health status correlates of malnutrition in the polish elderly population - Results of the Polsenior Study.

OBJECTIVE: The aim of the study was to analyze health-related factors associated with poor nutritional status (PNS) of a representative group of Polish older people, based on data from the PolSenior project (the first nation-wide study of Polish senior citizens). PATIENTS AND METHODS: Nutritional status was assessed in 3751 community-dwelling older people (1770 females, mean age: 77.4±8.0 years) using the Mini Nutritional Assessment - Short Form. Elements of comprehensive geriatric assessment (cognitive and mood screening), selected medical data were analyzed in relation to the nutritional status. These were: the number of medications, the number of chronic diseases, selected diseases potentially related to malnutrition (anaemia, stroke, peptic ulcer, Parkinson's disease, cancer - past or present), total edentulism, use of dentures, and chronic pain. RESULTS: PNS was observed in 44.2% of participants. Female sex [OR 1.72, 95% Cl (1.45-2.04)], advanced age [OR 2.16 (1.80-2.58)], symptoms of depression [OR 11.52 (9.24-14.38)], cognitive impairment [OR 1.52 (1.20-1.93], multimorbidity [OR 1.27 (1.04-1.57)], anaemia [OR 1.80 (1.41-2.29)] and total edentulism [OR 1.26 (1.06-1.49)] were independently correlated with PNS. CONCLUSIONS: PNS in Polish elderly population is strongly related to the occurrence of symptoms of depression. People in advanced age with symptoms of depression, cognitive impairment, multimorbidity, anaemia and total edentulism should be screened and monitored for early symptoms of malnutrition.

Cardiovascular Risk Factors and Markers of Atherosclerosis in Stable Kidney Transplant Recipients.

BACKGROUND: There is limited evidence regarding the risk factors influencing vascular injury in kidney transplant recipients, except for accelerated vasculopathy and endothelial dysfunction in the pre-transplantation period of end-stage renal failure. Therefore, we performed a cross-sectional study to evaluate the role of traditional and novel or potential nontraditional risk factors in vascular and endothelial dysfunction in a cohort of stable kidney transplant recipients. METHODS: One hundred forty-two kidney transplant recipients at 8.4 ± 1.8 years after transplantation were enrolled into the study. Different markers of vascular injury, such as carotid intima-media thickness (IMT), pulse wave velocity (PWV), and peripheral arterial tonometry (PAT), were assessed. Inflammatory markers, oxidative stress and endothelial function surrogate markers, adhesion molecules, and parathormone and osteoprotegerin levels were measured. RESULTS: Among traditional risk factors, only age, pre-transplantation diabetes, left ventricular hypertrophy (LVH) and cardiovascular disease (CVD) were related to increased IMT and PWV, whereas PAT values were significantly decreased only in diabetics and patients with CVD and were similar in patients with and without LVH. In multivariate regression analysis, IMT was explained by age, previous CVD episodes, and higher high-sensitivity C-reactive protein levels, and PWV by age and pre-transplantation diabetes. The regression analysis failed to find any significant explanatory variables for PAT. CONCLUSIONS: 1. In stable kidney transplant recipients, age, pre-transplantation diabetes, previous cardiovascular episode, and systemic microinflammation were predictors of vascular injury. 2. PAT is poorly associated with traditional CV risk factors and does not correspond with levels of biochemical markers of endothelial dysfunction in those patients.

Long-Term Outcomes of Kidney and Simultaneous Pancreas-Kidney Transplantation in Recipients With Type 1 Diabetes Mellitus: Silesian Experience.

BACKGROUND: Kidney transplantation (KTx) markedly reduces mortality in patients with end-stage kidney disease (ESKD) caused by type 1 diabetes mellitus (T1DM). The outstanding issue is whether transplantation should be limited only to KTx, with further insulinotherapy, or combined with pancreas transplantation in patients with ESKD/T1DM. The goal of this study was to compare the results of simultaneous pancreas-kidney transplantation (SPKTx) and deceased donor KTx and to identify factors affecting patient and kidney graft survival in patients with ESKD/T1DM. METHODS: Eighty-seven deceased donor KTx and 66 SPKTx operated on in the Silesia region of Poland between 1998 and 2013 were included in the retrospective analysis. RESULTS: During the mean 6.7 ± 3.6 years of follow-up, fewer cardiovascular episodes were observed in SPKTx recipients than in KTx recipients (1.5% vs 12.6%; P < .05). Five-year patient survival (80.7% in SPKTx vs 77.5% in KTx) and kidney graft survival (66.1% in SPKTx vs 70.4% in KTx) did not differ between study groups. There were no differences in patient survival (log-rank test, P = .99) or kidney graft survival (P = .99) based on Kaplan-Meier curves. Multivariable Cox proportional hazard analysis failed to identify factors explaining patient and kidney graft survival. Five-year pancreas graft survival was 58.9%. SPKTx recipients had significantly higher estimated glomerular filtration rates during the 7-year posttransplant period and less frequently developed proteinuria (6.1% vs 23%; P < .01). CONCLUSIONS: Pancreas transplantation reduced cardiovascular risk and prevented the development of proteinuria but did not improve patient and kidney graft survival in recipients with T1DM in the 7-year follow-up period.

Social and economic correlates of malnutrition in Polish elderly population: the results of PolSenior study.

OBJECTIVES: The aim of this study was to evaluate the prevalence of malnutrition in Polish elderly population and analyse its social and economic correlates based on the data from the PolSenior project, the first large-scale study of a representative group of Polish seniors. DESIGN: A cross-sectional population-based study. SETTING: All territorial provinces in Poland. PARTICIPANTS: 4482 community-dwelling respondents aged 65 years or above (women: n=2142, age=79.0±8.4 years; men: n=2340, age= 78.3±8.6 years). MEASUREMENTS: The nutritional status of participants was assessed through the Mini Nutritional Assessment Short Form (the revised MNA-SF). Out of social and economic correlates we evaluated age, sex, level of education, marital status, place of residence, living conditions and economic status. Economic status of the respondents was determined on the basis of questions on how well they could manage their own budgets. Those who could afford only the cheapest food or clothes were considered the group of self-reported poverty. RESULTS: Frequency of malnutrition in the PolSenior population accounted for 7.5% (in 5.0% men and 9.0% women; p<0.001). The risk of malnutrition was present in 38.9% (33.3% men and 42.4% women; p<0.001). In our study female sex, older age, unmarried status, living in a rural area and self-reported poverty were independent correlates of malnutrition. CONCLUSIONS: Our data showed high prevalence of malnutrition and the risk of its development among the community-dwelling elderly people in Poland. Screening with MNA-SF should focus in particular on unmarried, poorly educated individuals, in late old age, living in rural areas and self-reporting a poor financial state, especially women.

No effect of pretransplantation bilateral nephrectomy on the resistive indices measured in the kidney allograft.

BACKGROUND: The cirrhotic kidney is the cause of sympathetic nervous system and the renin-angiotensin system activation leading to increased vascular resistance and arterial hypertension. The impact of unilateral or bilateral nephrectomy (UN or BN) performed before kidney transplantation on kidney graft intrarenal resistance has not been assessed yet. The aim of this study is to assess the intrarenal resistance parameters measured by Doppler ultrasound in the transplanted kidney in either nephrectomized or non-nephrectomized kidney transplant recipients. METHODS: Among 686 consecutive successful first cadaveric kidney graft recipients transplanted from 1998 to 2012, we identified 43 patients who underwent BN and 49 patients who underwent UN. Patients with acute rejection episodes within an early post-transplantation period were excluded. We have analyzed both pulsatility (PI) and resistance (RI) indices measured within the kidney graft before discharge from the hospital. RESULTS: The prevalence of hypertension in the follow-up period after transplantation was significantly lower in the BN group (65.1% versus 81.0% in other groups). Neither BN nor UN influenced the PI or RI values. The mean PI and RI values were 1.50 (1.38-1.61) and 0.75 (0.73-0.78) in BN, 1.48 (1.37-1.58) and 0.76 (0.73-0.79) in UN, and 1.47 (1.43-1.50) and 0.74 (0.73-0.75) in non-nephrectomized patients, respectively. The results of multivariate analysis confirmed the lack of influence of nephrectomy on kidney graft resistive indices. CONCLUSION: BN before transplantation resulted in lower frequency of hypertension, but it did not affect the intrarenal vascular resistance measured in the kidney graft.

Neurological symptoms associated with cerebral hyperperfusion syndrome after CEA and CAS--one centre study.

BACKGROUND: There are two equivalent in efficacy methods of the treatment of carotid artery stenosis: endarterectomy (CEA) and stenting (CAS), in which the blood flow increases in most patients by 20-40% over baseline, in some exceeding 100% and being symptomatic and leading to cerebral hyperperfusion syndrome (CHS). AIM: The aim of this study is to analyze the structure of neurological symptoms associated with CHS in patients with carotid artery revascularization. PATIENTS AND METHODS: Retrospective analysis included 1386 consecutive patients treated in the Department of General and Vascular Surgery between 2005 and 2011, with 625 of them were subjected to CEA and 761 to CAS. If neurological symptoms occurred, patients were consulted by a neurologist and ultrasonography (USG) examination and CT were performed. Neurological symptoms in patients with new onset of headache ipsilateral to the carotid revascularization were extracted from medical records and nursing documentation. RESULTS: Neurological symptoms attributed to CHS were observed in 66 (10.6%) of CEA and 61 (8.0 %) of CAS group. The frequency was similar in both groups (p = 0.43). The occurrence of epileptic attacks was similar in both study groups. The only difference was the less frequent falling of the lip in CAS group. Transient bradycardia and/or hypotension were observed in CAS (8.8% vs. 10.4% and 1.3% vs. 1.3%, respectively). No difference in stroke appearance between groups were found. CONCLUSIONS: The occurrence of neurological symptoms attributable to cerebral hyperperfusion syndrome after carotid artery revascularization in short term observation is similar regardless of the method used.

Resting energy expenditure and gut microbiota in obese and normal weight subjects.

OBJECTIVES: It is suggested that gut microbiota play a role in the pathogenesis of obesity enhancing energy utilization from digested food. The influence of gut microbiota on resting energy expenditure (REE) has not been evaluated yet. AIM: The aim of the study is to assess the composition on gut microbiota and its association with REE in obese and normal weight subjects. SUBJECTS AND METHODS: REE measurement and semi-quantitative analysis of gut microbiota composition in aerobic and anaerobic conditions were performed in 50 obese and 30 normal weight subjects without concomitant diseases. RESULTS: A count of bacterial colony was greater in obese than in normal weight subjects. However, the proportion of Bacteroides spp. and Firmicutes was similar in both study groups. A positive correlation between REE (kcal/d) and total bacterial count (r = 0.26, p < 0.05), as well as between REE and the percentage of Firmicutes (r = -0.24, p < 0.05) was found. The multiple regression analysis did not prove an independent impact of total bacterial as well as Bacteroides spp. and Firmicutes counts on REE. CONCLUSIONS: The composition of gut microbiota is not associated with the level of resting energy expenditure. The proportion of Bacteroides and Firmicutes in gut microbiota is not related to body mass.

The influence of Body Mass Index on chronic venous disorders therapy.

AIM: Obesity is of importance among the risk factors predisposing for chronic venous disorders (CVD). Little is known how obesity affects the management of CVD. As the data concerning the treatments of CVD in the obese are incomplete, we performed an analysis of the different CVD therapies managements with respect to body mass index and the obesity. METHODS: We analyzed 9797 CVD patients from of a previous large national CVD survey, in regard to their Body Mass Index (BMI), CVD class and CVD therapies. Among them 2213 patients presented class I, 516 class II or morbid obesity. RESULTS: BMI was significantly associated with the method of CVD therapy. Logistic regression showed that venoactive drugs are preferentially used except in class I obesity patients but also when therapy is managed by general practitioner. Logistic regression analysis showed that class II and morbid obesity is associated with more frequent prevalence of previous surgical procedures related to CVD (OR=2.62 with 95% confidence interval of [2.16-3.17]) and topical agent use, (OR=1.77, [1.38-2.25]) but with a significant decreased compliance with compression therapy (OR=0.74, [0.61 - 0.89]), regardless of the clinical course of the disease, and socio-demographic factors. While class I obesity increased the adherence with VADs. CONCLUSION: The therapy of CVD is affected by body mass index. Class II and morbid obese CVD patients are less frequently compliant with compression therapy but are willing to accept surgical procedures and the use of topical agents.

Plasma level of N-terminal pro brain natriuretic peptide (NT-proBNP) in elderly population in Poland--the PolSenior Study.

BACKGROUND: The brain natriuretic peptides (BNP, NT-proBNP) are useful diagnostic markers of heart failure (HF), as exemplified by the ESC Heart Failure guidelines. The PolSenior project was an epidemiological study carried out to examine medical, psychological and socioeconomic aspects of aging in Poland. The aim of this study is an epidemiological description of HF based on elderly population from the PolSenior Study, stratified by NT-pro-BNP concentration values. MATERIAL AND METHODS: The research sample included 4979 respondents (2567 males and 2412 females) split into six equally sized age groups of elderly individuals. The study consisted of three visits performed by trained nurses and included a questionnaire survey, comprehensive geriatric assessment and blood and urine sampling with more than 50 biochemical parameters measured. Serum NT-pro-BNP was measured by electrochemiluminescence method (ECLIA). RESULTS: The prevalence of chronic kidney disease (CKD) (77.8%) and atrial fibrillation (39.5%), number of hospitalizations (23.7%) and number of patients treated with HF drugs were highest in NT-proBNP > 2000 pg/ml group and least frequent in NT-proBNP < 400 pg/ml group. Obese patients had significantly more frequently NT-proBNP values < 400 pg/ml (73.0%) and less frequently NT-proBNP values >2000 pg/ml (2.8%). Age over 70 years and male gender were associated with the increased NT-pro-BNP (> 400 pg/ml) (OR 1.41; CI 1.20-1.65 for male gender). CONCLUSIONS: We conclude that CKD and atrial fibrillation are associated with the occurrence of increased NT-pro-BNP, the surrogate for HF in elderly population. On the contrary, overweight or obesity is associated with lower prevalence of HF in elderly.
