Biopsychosocial Variables in Male Schizophrenic Patients: A Comprehensive Comparison with Healthy Controls.

OBJECTIVE: this study aims to comprehensively compare neuropsychological, psychopathological, anthropometric, biochemical, pharmacological, and lifestyle variables between 27 male schizophrenic patients (SZ group) and 30 age- and sex-matched healthy male controls (HC group). METHODS: participants underwent a battery of neuropsychological tests including the Trail Making Test (TMT), Stroop Color-Word Interference Test, and Verbal Fluency Test. Psychopathological symptoms in the SZ group were evaluated using the Positive and Negative Syndrome Scale (PANSS). Anthropometric measurements such as body weight, height, BMI, and waist circumference were taken. Biochemical markers measured included fasting glucose, total cholesterol, triglycerides, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and fasting insulin. Lifestyle factors were assessed through a questionnaire for the study of views and eating habits of people aged 16 to 65. RESULTS: the HC group outperformed the SZ group in the TMT_A test and the Stroop test, but no significant differences were observed in the TMT_B test or in phonemic fluency tests. No correlation was found between age and PANSS scores within the SZ group. Anthropometrically, the SZ group had higher body weight, waist circumference, and BMI, with no difference in height. Biochemically, the HC group had higher HDL cholesterol levels but lower insulin and insulin resistance indices. Pharmacological assessment showed a more significant impact on body weight among SZ patients taking second-generation antipsychotics. Lifestyle factors such as diet and screen time were comparable between groups, but the SZ group reported longer sleep duration and lower leisure time activity. CONCLUSIONS: our study highlights distinct neuropsychological, pharmacological, anthropometric, and biochemical differences between male schizophrenic patients and healthy controls. The results underscore the complexity of schizophrenia and point toward the need for a multi-faceted approach to its management and understanding.

Emergency contraception - A review.

Emergency contraception (EC), or postcoital contraception, is a therapy aimed at preventing unintended pregnancy after an act of unprotected or under-protected sexual intercourse. Options include both emergency contraceptive pills (most commonly containing levonorgestrel or ulipristal acetate) and insertion of an intrauterine device. The aim of this paper is to summarize current evidence surrounding the use of emergency contraceptives and to present an evidence-based approach to EC provision. Emergency contraception is a safe and effective option in preventing unwanted pregnancy, irrespective of age, weight, or breastfeeding status. Efforts should be made to increase their availability, as well as knowledge of these methods, both among patients and healthcare providers.

The Importance of 1-Year Protocol Biopsy in the Long-Term Prognosis of Kidney Transplants-5-Years Follow-Up.

BACKGROUND: Protocol biopsies are performed to detect subclinical pathologies that may lead to future graft dysfunction. However, they are not routinely performed interventions in every transplant center. There is no established regimen for performing them. PURPOSE: The study aimed to evaluate if protocol biopsies can improve long-term patient outcomes after detecting early disorders and modifying treatment. MATERIAL AND METHODS: Our observational study included 61 patients who underwent protocol biopsy 12 months after the transplantation. Based on the biopsy results, patients with abnormal histologic material (n = 37) were divided into 3 study groups as follows: patients with mild inflammatory lesions (n = 21), patients with interstitial fibrosis and tubular atrophy (IFTA) grade II to III (n = 12), and patients with BK virus nephropathy (n = 4). The control group (n = 24) included kidney recipients with IFTA 0 to I grade. Outcomes after 5-year follow-up were evaluated. RESULTS: Five years after the biopsy, patients in the control group had stable graft function (5-year change in serum creatinine was -0.09 mg/dL). An increase in serum creatinine levels was observed in patients with IFTA II to III compared with the control group (0.14 mg/dL, P = .04). Immunosuppressive treatment was modified in the group with mild inflammatory changes and in the BKV group after the biopsy result. In the group with mild inflammatory lesions, renal function was stable (change of serum creatinine was -0.01 mg/dL, P = .51). In the BKV nephropathy group, there was a significant reduction in serum creatine levels (-0.48 mg/dL, P = .016). The analysis showed no diagnostic value for serum creatinine concentration (95% CI 0.49-0.78, P = .08). CONCLUSIONS: Protocol biopsies are useful for detecting early pathologies and preventing allograft failure. They greatly benefit patients with detectable pathology that can be treated or in whom therapy modification is possible.

Potential utility of urinary chemokine CCL2 to creatinine ratio in prognosis of 5-year graft failure and mortality post 1-year protocol biopsy in kidney transplant recipients.

BACKGROUND: Chemokines (chemotactic cytokines) are small proteins which are engaged in many pathophysiological processes, including inflammation and homeostasis. In recent years, application of chemokines in transplant medicine was intensively studied. The aim of this study was to determine the utility of urinary chemokines CCL2 (C-C motif ligand 2) and CXCL10 (C-X-C motif chemokine ligand 10) in prognosis of 5-year graft failure and mortality post 1-year protocol biopsy in renal transplant recipients. METHODS: Forty patients who had a protocol biopsy 1 year after renal transplantation were included. Concentrations of CCL2 and CXCL10 in urine with reference to urine creatinine were measured. All patients were under the supervision of one transplant center. Long-term outcomes within 5 years after 1-year posttransplant biopsy were analyzed. RESULTS: Urinary CCL2:Cr at the time of biopsy was significantly increased in patients who died or had graft failure. CCL2:Cr was proven to be a significant predictor of 5-year graft failure and mortality (odds ratio [OR]: 1.09, 95% confidence interval [CI]: 1.02-1.19, p = .02; OR: 1.08, 95% CI: 1.02-1.16, p = .04; respectively). CONCLUSION: Chemokines are easily detected by current methods. In the era of personalized medicine, urinary CCL2:Cr can be considered as a factor providing complementary information regarding risk of graft failure or increased mortality.

Epileptiform activity in the acute phase of stroke predicts the outcomes in patients without seizures.

Background and purpose: The abnormalities in EEG of stroke-patients increase the risk of epilepsy but their significancy for poststroke outcome is unclear. This presented study was aimed at determining the prevalence and nature of changes in EEG recordings from the stroke hemisphere and from the contralateral hemisphere. Another objective was to determine the significance of abnormalities in EEG in the first days of stroke for the post-stroke functional status on the acute and chronic phase of disease. Methods: In all qualified stroke-patients, EEG was performed during the first 3 days of hospitalization and at discharge. The correlation between EEG abnormalities both in the stroke hemisphere and in the collateral hemisphere with the neurological and functional state in various time points was performed. Results: One hundred thirty-one patients were enrolled to this study. Fifty-eight patients (44.27%) had abnormal EEG. The sporadic discharges and generalized rhythmic delta activity were the most common abnormalities in the EEG. The neurological status on the first day and the absence of changes in the EEG in the hemisphere without stroke were the independent factors for good neurological state (0-2 mRS) at discharge. The age-based analysis model (OR 0.981 CI 95% 0.959-1.001, p = 0.047), neurological status on day 1 (OR 0.884 CI 95% 0.82-0.942, p < 0.0001) and EEG recording above the healthy hemisphere (OR 0.607 CI 95% 0.37-0.917, p = 0.028) had the highest prognostic value in terms of achieving good status 90 days after stroke. Conclusions: Abnormalities in EEG without clinical manifestation are present in 40% of patients with acute stroke. Changes in EEG in acute stroke are associated with a poor neurological status in the first days and poor functional status in the chronic period of stroke.

Relevance of admission hyperglycaemia and diabetes mellitus to efficacy and safety of mechanical thrombectomy in stroke patients.

INTRODUCTION: The relevance of diabetes mellitus (DM) to the efficacy of mechanical thrombectomy (MT) has been the subject of few studies and with only inconclusive results. OBJECTIVES: This study aimed to evaluate the effect of DM and admission hyperglycaemia on the efficacy and safety of MT in stroke patients. MATERIAL AND METHODS: This retrospective study analysis focused on the relevance of admission hyperglyacemia and DM to the functional status of patients treated with MT at the Upper Silesian Medical Centre of the Silesian Medical University in Katowice, Poland. RESULTS: 417 stroke patients (median age 70 years) were qualified for the study. There were 103 patients (24.70%) with DM. Admission hyperglycaemia ≥ 140 mg% was found in 91 patients (21.82%), of whom 69 were diagnosed with DM before or during hospitalisation. The parameters with the strongest effect on the functional status on days 7, 90 and 365 were: age, and neurological status according to the National Institutes of Health Stroke Scale (NIHSS) on the first day of ischaemic stroke before MT. The angiographic effect indirect after MT and patient functional status on days 7, 90 and 365 were comparable between the groups, regardless of the DM burden. The frequency of symptomatic intracranial bleeding 24 hours after MT was comparable between patients with and patients without DM (p = 0.092). Model based on parameters were age, NIHSS on the first day of ischaemic stroke, an when score in Thrombolysis In Cerebral Infarct (TICI) showed good predictive attributes for the functional status of patients in the acute period (day 7). Age, a lack of admission hyperglycaemia, and the neurological state on day 1 of ischaemic stroke (before MT) were the key parameters for a favourable outcome (≤ 2 points on the modified Rankin Scale, mRS) on day 90. Admission hyperglycaemia ≥ 140 mg/dL, regardless of the presence or absence of DM, had a negative effect on achieving a good functional status one week after stroke onset. CONCLUSIONS: Diabetes mellitus has a neutral effect on the angiographic and clinical outcomes of mechanical thrombectomy in stroke patients. It does not increase the risk of intracranial haemorrhage after instrumental therapy. It is admission hyperglycaemia, rather than diabetes mellitus, that is a predictor of poor functional status in patients treated with thrombectomy. According to our results, the patient's neurological status, age, and the outcome of thrombectomy are relevant to the functional status in the acute ischaemic stroke period.

Factors associated with the symptomatic status of carotid artery stenosis: identification in a cross-sectional study and development of a scoring system.

INTRODUCTION: The identification of asymptomatic patients at high risk of internal carotid artery (ICA) stenosis destabilization and symptom occurrence is crucial for prognosis estimation. OBJECTIVES: This study aimed to determine differences between patients with symptomatic and asymptomatic ICA stenosis and to develop a predictive model for the risk of symptomatic stenosis based on data collected in routine clinical practice. PATIENTS AND METHODS: The study included 163 patients with asymptomatic and 182 patients with symptomatic ICA stenosis greater than 70%. The study groups were compared in terms of stroke risk factors and comorbidities, coexisting ICA stenosis on the contralateral side, atherosclerosis in other arterial territories, and the morphology of atherosclerotic plaque assessed by transcervical ultrasound. RESULTS: Independent risk factors for symptomatic ICA stenosis included: male sex (odds ratio [OR], 2.94; 95% CI, 1.87-4.32; P <0.001), diabetes (OR, 2.86; 95% CI, 1.62-5.12; P <0.001), body mass index >25 kg/m2 (OR, 1.81; 95% CI, 1.72-1.86; P <0.001), chronic kidney disease (OR, 3.34; 95% CI, 1.34-8.87; P = 0.007), increased­risk features of ultrasound plaque morphology (OR, 2.52; 95% CI, 1.29-3.72; P = 0.009), and coexisting atherosclerosis in 3 or 4 vascular areas (OR, 3.72; 95% CI, 1.77-7.23; P <0.001).The sensitivity and specificity of the scoring model designed to estimate the risk of symptomatic ICA stenosis reached 77.6% and 76.9%, respectively. CONCLUSIONS: This cross­sectional study indicated that the analysis of selected imaging and clinical parameters may enable clinicians to estimate the risk of symptomatic ICA stenosis. The proposed scoring system requires further prospective validation.

The Association of SNPs Located in the CDKN2B-AS1 and LPA Genes With Carotid Artery Stenosis and Atherogenic Stroke.

Introduction: The aim of this project was to assess the prevalence of four selected SNPs rs4977574 and rs7857345 (CDKN2B-AS1 gene) and rs3798220 and rs10455872 polymorphisms (the LPA gene) in the subpopulation of patients with symptomatic and asymptomatic carotid stenosis. Material and Methods: This study included 623 individuals (244 patients with symptomatic carotid artery stenosis, 176 patients with asymptomatic carotid artery stenosis and 203 healthy people. All the participants underwent neurological examination, duplex Doppler ultrasound examination and molecular procedures. Results: In the first part of the analysis the assiociation of SNPs with stroke/TIA was investigated. The association was seen in symptomatic vs. control group for two SNPs: rs4977574 and rs7857345 (CDKN2B-AS1 gene); genotype distributions for rs4977574 and rs7857345 showed the statistically significant differences between patients and controls (p = 0.043 and 0.017, respectively). No association was observed for rs3798220 and rs10455872 located in the LPA gene. There were statistically significant differences between asymptomatic patients vs. control group in genotype distribution for the SNPs located in CDKN2B-AS1: rs4977574 and rs7857345 (p = 0.031 and 0.0099, respectively); and for the rs3798220 (LPA gene; p = 0.003); however, statistically significant differences did not occur for the rs10455872 polymorphism located in the LPA gene. In the next part of the evaluation, a comparison between symptomatic and asymptomatic patients was performed. Significant differences in genotype distribution were seen only for the rs3798220 polymorphism located in the LPA gene (p = 0.0015). The analysis of the prevalence of the polymorphisms in the total group (symptomatic and asymptomatic) patients in comparison with the control group showed significant differences for three polymorphisms: rs4977574 and rs7857345 (CDKN2B-AS1 gene; p = 0.015 and 0.0046, respectively) and rs3798220 (LPA gene, p = 0.044). Conclusions: The present research on the carotid artery stenosis patient cohort suggests the significant association between the rs4977574, rs7857345 and rs3798220 polymorphisms and carotid artery stenosis as well as between the rs4977574 and rs7857345 polymorphisms and atherogenic stroke. The rs4977574 and rs7857345 polymorphisms in patients with carotid artery stenosis appear to affect a person's susceptibility to atherogenic brain ischemia. Our results need to be replicated in future studies.

The importance of atrial fibrillation and selected echocardiographic parameters for the effectiveness and safety of thrombolytic therapy in patients with stroke.

BACKGROUND: The efficacy and safety of thrombolytic therapy in stroke depend on multiple factors. The aim of this study was to evaluate the significance of atrial fibrillation the prognosis in terms of the functional status in patients with stroke treated with intravenous thrombolysis. An additional aim was also to assess the potential significance of reduced ejection fraction (EF) and enlarged left atrium (LA) of the heart for the prognosis in patients with stroke who underwent thrombolytic therapy. METHODOLOGY: A prospective study involved enrollment of 222 patients, mean age of 72 years with first-in-life ischemic stroke. In all participants there were realized procedures as follows: neurological status before administering rt-PA (NIHSS), selected echocardiographic parameters, functional status on the 14th day from the onset (mRankin scale) and analysis the bleeding events. RESULTS: Atrial fibrillation was significantly more frequent in women than men; females had higher CHA2DS2VASc scores and heavier neurological conditions on day 1 of stroke. Two independent factors for poor prognosis (3-5 points by mRankin) were found: the NIHSS score and the CHA2DS2VASc score ≥3. We identified 2 independent factors for death within 14 days from the onset: the result by NIHSS and the EF. The NIHSS score turned out to be the only independent predictor of hemorrhage during hospitalization: RR 1.19; CI [1.06-1.33]; p=0.003; p for model=0.0025. CONCLUSIONS: The presence of atrial fibrillation worsens the patient's prognosis in terms of the functional status and survival during the acute period of stroke in patients treated with intravenous thrombolysis. Higher NIHSS and CHA2DS2VASc scores and reduced EF in patients with stroke treated with thrombolysis are the predictors of unfavorable short-term prognosis.
