RESUMO
BACKGROUND: Aim of our study was to estimate the prevalence of comorbid conditions and adverse health behaviors in relapsing-remitting multiple sclerosis (RRMS) patients and evaluate association between comorbidity and MS outcomes (relapse rate, fatigue and quality of life) in Lithuanian setting. METHODS: A prospective cohort study was carried out in the MS center of Lithuanian University of Health Sciences Hospital Kaunas clinics from November 2016 to March 2021. People with MS filled a self-report comorbidity and adverse health behavior questionnaire, visual analogue fatigue scale (VAFS), a Short Form 36 (SF-36) v2 health related quality of life questionnaire (QoL). Information about disability and relapses was acquired from medical documentation and Lithuanian MS registry at baseline and after 24-month observational period. Chi square, t-test, ANOVA, Mann-Whitney U were used for basic statistical evaluation. Multivariable logistic regression models were used to prognose MS outcomes in association to comorbidity and adverse health behaviors, adjusting for age and baseline disability. RESULTS: Of 230 RRMS patients, 167 (72.6%) were women, average age was 42 years. 207 persons were followed through the observational period and included into relapse analysis. 112 (48.7%) of participants reported having at least one comorbidity, the most prevalent were arterial hypertension (19.1%) depression (16.5%) and anxiety (14.8%). People with comorbidities had higher fatigue (6.6 vs. 5.3, p < 0.001) and lower quality of life (overall SF-36 46.3 vs 59.1, p < 0.001). People consuming alcohol had fewer relapses per 24 months (0.56 vs. 0.82, p = 0.01), lower fatigue (5.7 vs. 6.4, p = 0.03), better quality of life (overall SF-36: 56.8 vs. 45.6, p < 0.001), compared to abstinents. In regression models, comorbidities were associated with severe (>7 VAFS) fatigue (Exp(B)=1.98, 95% CI [1.02, 3.86], p = 0.043), diminished (<50 SF-36) QoL (Exp(B)=3.50, 95% CI [1.72, 7.09], p = 0.001). Depression was independently associated with lower QoL (Exp(B)= 2.86, 95% CI [1.04, 7.88], p = 0.042) and severe fatigue (Exp(B)=4.65, 95% CI [2.39, 9.01], p < 0.001); anxiety with diminished QoL (Exp(B)= 4.99, 95%CI [1.67, 14.92], p = 0.002). Light alcohol consumption (compared to abstinents) was associated with decreased risk for: relapse during 24 months (Exp(B)=0.44, 95% CI[0.24, 0.77], p = 0.005), severe fatigue (Exp(B)=0.48, 95% CI [0.24, 0.98], p = 0.042) and lower QoL (Exp(B)= 0.32, 95% CI [0.16, 0.65], p = 0.002). CONCLUSION: Comorbidity is a relevant issue in multiple sclerosis as half of people with MS report concomitant conditions. Hypertension, depression, and anxiety are especially prevalent in MS. In our study, comorbidity is associated with quality of life and fatigue, but not relapse rate. Depression and anxiety are independently associated with lower quality of life and higher fatigue. Light alcohol consumption is associated with reduced relapse risk, less fatigue and better quality of life. Overweight and tobacco smoking do not seem to have negative impact on MS outcomes in our sample.

BACKGROUND: The benefits of weight loss programs on mood, cognitive, and motor behavior are largely limited to those of calorie restriction or exercise alone. Our aim was to investigate the effect of combined calorie restriction and aerobic exercise intervention on mood, brain activity, and cognitive and motor behavior in overweight and obese women. METHODS: Participants aged 36-56 years were randomized to either a control or an experimental group (aerobic exercise + 12.5% energy intake reduction) for a 6-month period. Changes in brain-derived neurotrophic factor levels, mood, prefrontal cortex activity, cognitive and motor performance were assessed. RESULTS: Confusion and depression increased in the control group (P < .05), whereas tension decreased in the experimental group (P < .05). Brain-derived neurotrophic factor level and learning of a speed-accuracy task remained unchanged. Although prefrontal cortex activity and executive functions were not affected, the reaction time of visual scanning and associative learning were improved in the experimental group (P < .05). An improvement in reaction time during the speed-accuracy task was observed (P < .05). CONCLUSION: Combined calorie restriction and aerobic exercise intervention improved the psychosocial state, had little impact on cognition, and no effect on brain activity and learning of the speed-accuracy task.

OBJECTIVES: Neuromyelitis optica (NMO) is frequently associated with aquaporin-4 autoantibodies (AQP4-Ab); however, studies of NMO in Lithuania are lacking. Therefore, the main objective of our study is to assess positivity for AQP4-Ab in patients presenting with inflammatory demyelinating central nervous system (CNS) diseases other than typical multiple sclerosis (MS) in Lithuania. MATERIALS AND METHODS: Data were collected from the two largest University hospitals in Lithuania. During the study period, there were 121 newly diagnosed typical MS cases, which were included in the MS registry database. After excluding these typical MS cases, we analyzed the remaining 29 cases of other CNS inflammatory demyelinating diseases, including atypical MS (n = 14), acute transverse myelitis, TM (n = 8), acute disseminated encephalomyelitis, ADEM (n = 3), clinically isolated syndrome, CIS (n = 2), atypical optic neuritis, ON (n = 1), and NMO (n = 1). We assessed positivity for AQP4-Ab for the 29 patients and evaluated clinical, laboratory, and instrumental differences between AQP4-Ab seropositive and AQP4-Ab seronegative patient groups. RESULTS: AQP4-Ab test was positive for three (10.3%) patients in our study, with initial diagnoses of atypical MS (n = 2) and ADEM (n = 1). One study patient was AQP4-Ab negative despite being previously clinically diagnosed with NMO. There were no significant clinical, laboratory, or instrumental differences between the groups of AQP4-Ab positive (3 [10.3%]) and negative (26 [89.7%]) patients. CONCLUSIONS: AQP4-Ab test was positive for one-tenth of patients with CNS inflammatory demyelinating diseases other than typical MS in our study. AQP4-Ab testing is highly recommended for patients presenting with not only TM and ON but also an atypical course of MS and ADEM.

There is a lack of equipment and methods for the reliable and valid measurements of human neuromuscular control. To overcome this limitation, an analyzer of dynamic parameters (DPA-1) of human hand and leg movements was constructed by Kaunas University of Technology and "Katra" engineers in collaboration with the Lithuanian Academy of Physical Education. The aim of the study was to determine the reliability and validity of the tests performed on the DPA-1 in healthy and injured subjects after the anterior cruciate ligament (ACL) reconstruction surgery. MATERIAL AND METHODS. The men who had undergone a unilateral ACL reconstruction (n=17, on the average 3.8 months [SD, 2.1] after the surgery) and healthy untrained men (n=17) performed the research protocol twice within 24 hours in between. Average reaction time, mean and maximal movement speed, time to reach maximal speed, and movement distance of the right and left feet for the patients and of the dominant foot for the healthy subjects using the DPA-1 as well as the scores of isokinetic muscle strength and self-assessment tests were registered. RESULTS. There was a significantly reduced concentric peak torque on the injured knee compared with the uninjured knee during knee extension, and the mean score of the Lysholm scale for the injured knee was 69.1 (SD, 13.7) (P<0.05, compared between legs). The test-retest reliability for all the DPA-1 tests varied from 0.68 to 0.94 (P<0.05). However, there were no significant differences in most variables measured by the DPA-1 between injured knee, uninjured knee, and control knee. CONCLUSIONS. The results revealed low validity of the DPA-1 tests for the evaluation of patients following ACL surgery, despite the reliability of these tests varied from moderate to very high.
