Insomnia, Fatigue, Bladder Disorders and Mood Disorders among Polish Patients with Multiple Sclerosis: Cross-Sectional Study.

BACKGROUND: To investigate the prevalence of sleep disorders in patients with multiple sclerosis (PwMS) in comparison to healthy controls (HCs), we aim to explore the correlation between sleep disorders and fatigue, bladder dysfunction, mood disorders in PwMS. METHODS: This study involved 175 PwMS and 115 HCs. We conducted a self-administered survey using questionnaires (the authors' questionnaire, the Athens Insomnia Scale (AIS), the Epworth Sleepiness Scale (ESS), the Modified Fatigue Impact Scale (MFIS), the Fatigue Severity Scale (FSS), the Hospital Anxiety and Depression Scale (HADS), and the Numerical Rating Scale (NRS). The neurological disability was determined using Expanded Disability Status Scale. Logistic regression was used to estimate odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS: According to AIS, insomnia was found in 20.6% of PwMS compared to 9.6% of HCs (p < 0.001). Comparing female and male PwMS, we observed that insomnia was more prevalent among female PwMS (25.95% vs. 4.55%, respectively, p < 0.05). Excessive daytime sleepiness was more prevalent in female PwMS (p < 0.05). Female PwMS were more fatigue based on the FSS and the MFIS (p < 0.05). Bladder disorders were observed in 39.43% of PwMS and were significantly linked to MS (p < 0.001). Sleep disturbances were associated with anxiety disorders (OR = 0.22, 95% CI 0.12-0.32 p < 0.001), bladder dysfunction (OR = 0.52 95% CI 0.16-0.87 p < 0.05), and female gender (OR = 0.49, 95% CI 0.037-0.94 p < 0.05). CONCLUSIONS: Insomnia is prevalent among PwMS. Our study revealed independent predictors of sleep disturbances among PwMS: female gender, bladder disorders, and anxiety.

Analysis of seroconversion following COVID-19 vaccination among multiple sclerosis patients treated with disease-modifying therapies in Poland.

CLINICAL RATIONALE FOR THE STUDY: The rapid spread of SARS-CoV-2 throughout the world has highlighted the importance of vaccinations to control the pandemic and to protect people at risk for severe disease courses. Disease-modifying therapies (DMT) in multiple sclerosis (MS), whether immunomodulatory or immunosuppressive, may affect the immune response. Therefore, the question arose as to whether these vaccinations would be effective. AIM OF THE STUDY: We planned a study to assess the immune response to SARS-CoV-2 vaccines by type of therapy. MATERIAL AND METHODS: Participants were recruited from 14 Polish MS centres. The data was obtained by neurologists using a questionnaire. We collected data on 353 MS patients (269 females, 84 males) who received complete primary SARS-CoV-2 vaccination. All persons with MS (PwMS) were treated with disease-modifying therapies. RESULTS: 305 out of 353 PwMS (86.4%) were positive for IgG Abs against SARS-CoV-2 S domain S1 Ag after vaccination. A strong immune response was noted in 129 PwMS (36.5%). The rate of seroconversion after SARS-CoV-2 vaccination in PwMS who received immunomodulatory DMTs (interferon beta, glatiramer acetate, teriflunomide, dimethyl fumarate, natalizumab) was 91.5%, in PwMS receiving immune reconstruction therapy (alemtuzumab, cladribine) was 92%, and in immunosuppressive DMTs (fingolimod, ocrelizumab), the seroconversion rate was 59%. CONCLUSIONS AND CLINICAL IMPLICATIONS: Our study shows that, in PwMS receiving immunomodulatory therapy, the immune response to vaccination is generally excellent. Even in immunosuppressive patients, seroconversion is satisfactory.

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.

Ministernotomy for aortic valve replacement improves early recovery and facilitates proper wound healing - forced propensity score matching design with reference full sternotomy.

Introduction: With the development of less invasive techniques ministernotomy has become an increasingly popular choice for minimally invasive aortic valve replacement (MIAVR). However, a large discrepancy in the published results, often derived from the center's own experience, intensifies the need for further re-evaluation in order to better define the real impact of the ministernotomy approach on postoperative clinical condition in short- and long-term observation. Aim: To assess the safety and efficacy of MIAVR in comparison to a reference full sternotomy AVR (FSAVR). Material and methods: Between January 2004 and January 2018, 2386 patients underwent isolated surgical aortic valve replacement (AVR) at our institution. 620 patients were treated minimally invasively (MIAVR) and 1766 patients received FSAVR. Forced propensity score 1 : 1 matching and conditional regressive methods were introduced, ensuring valid comparison and correct estimation. Ultimately, 557 well allocated pairs of treated and control patients were included. Results: In-hospital mortality was low and comparable (1.26% for MIAVR, 1.62% for FSAVR). No significant differences in terms of serious adverse events were found, although in patients undergoing MIAVR there tended to be lower incidence of neurological complications (OR = 0.72; p = 0.09) and low output syndrome (OR = 0.66; p = 0.13). In addition to a much faster extubation and discharge from the ICU as well as improved blood management, MIAVR significantly reduced the risk of wound complications (OR = 0.31; p < 0.0010). Conclusions: MIAVR is a safe, effective and reproducible procedure providing at least as good results as FSAVR. Nevertheless, it should be especially recommended to obese, diabetic patients with pulmonary and mobility disorders in order to improve their early recovery.

Awareness of COVID-19 Symptoms, Risk Factors, and Vaccinations in Patients with Multiple Sclerosis.

Multiple Sclerosis (MS) is the most common chronic autoimmune disease of the central nervous system, affecting around 2.8 million people worldwide. Patients' knowledge about COVID-19 infection, and their proper protective actions, may reduce the risk of infection. The aim of this study was to assess the knowledge of patients with MS about SARS-CoV-2, COVID-19 illness, the relationship between MS and COVID-19, willingness to be vaccinated, and the impact of the pandemic on MS care. An original, anonymous, 35-items, self-reported questionnaire was used in both web-based and on-site survey formats. Two-hundred and forty-eight questionnaires were analyzed (mean age 40.8 ± 10.6 years, 77.8% women). Participants reported the use of multiple sources of information, and the most common were websites (77.8%) and television (59.3%). The majority of participants knew the correct symptoms of COVID-19 or transmission routes (94.4%), and accepted the pandemic's restrictions (96.8%). A total of 93.2% considered SARS-CoV-2 as highly infectious, and 69% thought they were at higher risk of being infected with SARS-CoV-2, mainly because of immunodeficiency (82.7%). Although most of them were afraid of COVID-19 (69.0%), only two-thirds wanted to be vaccinated. Patients who were afraid of COVID-19 had a 3.5-times higher chance to declare willingness for vaccination. A total of 29.8% patients claimed that the COVID-19 pandemic limited access to the healthcare system. This study shows that Polish patients with MS represent a good level of knowledge about COVID-19 disease, and acceptance for public rules, but their willingness for vaccinations is not sufficient. Country-wide educational campaigns should be conducted, particularly on the internet and TV. Restrictions in healthcare facilities should be balanced to secure access for patients with MS.

More for less - long-term survival modeling for surgical aortic valve replacement follow-up: The division between a ministernotomy and a full sternotomy approach.

BACKGROUND: This study aimed to assess long-term results after surgical AVR (sAVR) depending on the used surgical technique (ministernotomy vs. full sternotomy) and to determine which patient- and treatment-related attributes were most associated with shorter time to the main endpoint. METHODS: Out of 2147 patients, who underwent sAVR from January 2006 to December 2017, 615 patients were treated minimally invasively (MIAVR) and 1532 patients received conventional full sternotomy aortic valve replacement (FSAVR). Multiple Cox regressive models corresponding to the four major endpoints were developed. Long-term survival and a time to re-hospitalization for acute coronary syndrome, stroke, and heart failure (HF) were analyzed independently. Kaplan-Meier actuarial analysis was performed for univariate comparison. RESULTS: The median follow-up time was 71.9 months. No significant difference in terms of long-term survival was found between MIAVR and FSAVR (hazard ratio [HR], 0.99; P = 0.91). Novel advantages of MIAVR in preventing re-hospitalization for late cerebrovascular events and the progression of HF were observed (HR, 0.53; P = 0.03; HR, 0.64, P = 0.005; respectively). Importantly, for the late mortality risk, early in-hospital complications dominated. However, the baseline atrial fibrillation (AF), diabetes, pulmonary disease, and impaired mobility showed the strongest patient-specific prediction for the other three long-run models. CONCLUSIONS: MIAVR through ministernotomy provides at least as good long-term survival as FSAVR. Nevertheless, it should be recommended for diabetic, poor-mobility patients with pre-existing AF to reduce their high cerebrovascular risk and to limit the progression of HF. MIAVR also needs to be considered in patients with chronic lung diseases to improve their extremely poor survival prognosis.

The Impact of Vitamin D Low Doses on Its Serum Level and Cytokine Profile in Multiple Sclerosis Patients.

Vitamin D is known to have immunomodulatory properties and its deficiency is identified as an environmental risk factor for the development of autoimmune diseases, including multiple sclerosis. The aim of this study was to assess whether low-dose vitamin D supplementation could normalize the 25(OH)D serum levels in patients with relapsing-remitting multiple sclerosis (RRMS) and vitamin D deficiency (serum 25(OH)D < 75 nmol/L), and whether it may impact serum levels of selected cytokines. Among 44 patients (mean age 38.4 ± 10.1 years, 33 women and 11 men), after 12 months of low-dose vitamin D supplementation, serum levels of 25(OH)D normalized in 34 (77.3%) of the patients. Together with vitamin D increase, median levels of anti-inflammatory cytokines (IL10, TGF-ß) and regulatory IFN-γ increased, while proinflammatory IL-17 remained unchanged. Moreover, an increase of inorganic phosphorus levels and decrease of PTH levels were observed, but without changes in total calcium concentration. These results may indicate that long-term supplementation with low doses of vitamin D is sufficient to compensate its deficiency in patients with RRMS and may help to maintain beneficial anti-inflammatory cytokine profile.

[Hashimoto's encephalopathy - rare encephalopathy with good prognosis].

Hashimoto's encephalopathy (HE) is a rare neuropsychiatric syndrome associated with increased level of antithyroid antibodies. Two types of clinical manifestation can be described: a vasculitic type with stroke like episodes and diffuse progressive type with deterioration of mental function. Neurologic symptoms are present in euthyreosis as well as in thyroid dysfunction. Because of good response to immunosuppressive therapy, the prompt diagnosis and management of HE are crucial. In this study we present the review of current literature and discuss two representative cases.

Minimally invasive aortic valve replacement - pros and cons of keyhole aortic surgery.

Over the last twenty years, minimally invasive aortic valve replacement (MIAVR) has evolved into a safe, well-tolerated and efficient surgical treatment option for aortic valve disease. It has been shown to reduce postoperative morbidity, providing faster recovery and rehabilitation, shorter hospital stay and better cosmetic results compared with conventional surgery. A variety of minimally invasive accesses have been developed and utilized to date. This concise review demonstrates and discusses surgical techniques used in contemporary approaches to MIAVR and presents the most important results of MIAVR procedures.
