© 2020 Sports Medicine Australia Objectives: Para athletes with brain impairment are affected by hypertonia, ataxia and athetosis, which adversely affect starting, sprinting and submaximal running. The aim was to identify and synthesise evidence from studies that have compared the biomechanics of runners with brain impairments (RBI) and non-disabled runners (NDR). Design: Systematic review. Methods: Five journal databases were systematically searched from inception to March 2020. Included studies compared the biomechanics of RBI (aged > 14 years) and NDR performing either block-starts, sprinting, or submaximal running. Results: Eight studies were included, analysing a total of 100 RBI (78M:22F; 18–38 years) diagnosed with either cerebral palsy (n = 44) or traumatic brain injury (n = 56). Studies analysed block-starts (n = 3), overground sprinting (n = 3) and submaximal running (n = 2), and submaximal treadmill running (n = 1). Horizontal velocity during starts, sprinting and self-selected submaximal speeds were lower in RBI. During sprinting and submaximal running, compared with NDR, RBI had shorter stride length, step length, and flight time, increased ground-contact time, increased cadence, and reduced ankle and hip range of motion. In submaximal running, RBI had decreased ankle-power generation at toe-off. Conclusions: There is limited research and small sample sizes in this area. However, preliminary evidence suggests that RBI had lower sprint speeds and biomechanical characteristics typical of submaximal running speeds in NDR, including increased ground-contact times and reduced stride length, step length, and flight times. Meaningful interpretation of biomechanical findings in RBI is impeded by impairment variability (type, severity and distribution), and methods which permit valid, reliable impairment stratification in larger samples are required.

© 2019 Elsevier Ltd Background: Heidenhain variant of Cruetzfeldt Jacob Disease is a rare phenotype of the disease. Early and isolated visual symptoms characterize this particular variant of CJD. Other typical symptoms pertaining to muti-axial neurological involvement usually appear in following weeks to months. Commonly reported visual difficulties in Heidenhain variant are visual dimness, restricted field of vision, agnosias and spatial difficulties. We report here a case of Heidenhain variant that presented with very unusual symptoms of palinopsia and oscillopsia. Case presentation: A 62-year-old male patient presented with symptoms of prolonged afterimages following removal of visual stimulus. It was later on accompanied by intermittent sense of unstable visual scene. He underwent surgery in suspicion of cataratcogenous vision loss but with no improvement in symptoms. Additionally he developed symptoms of cerebellar ataxia, cognitive decline and multifocal myoclonus in subsequent weeks. On the basis of suggestive MRI findings in brain, typical EEG changes and a positive result of 14-3-3 protein in CSF, he was eventually diagnosed as sCJD. Conclusion: This case adds to the tally of handful reports of Heidenhain variant CJD in literature, particularly from India. Two atypical initial symptoms, namely hallucinatory palinopsia and paroxysmal oscillopsia were observed in the index case. Possible explanations of such phenomena in CJD have been explored in light of the available studies.

© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim Nanoporous glassy polymers are perspective materials for the fabrication of gas separation membranes, especially for the application of gaseous hydrocarbon separation. However, the drawback of such materials is the pronounced physical aging resulting in the dramatic drop of gas transport properties due to relaxation of high-free-volume fraction in time. Herein, a novel and readily available group of such glassy polymers is reported based on 5-alkylnorbornenes. These polymers are easily synthesized from dicyclopentadiene and α-olefins by Diels-Alder reaction and vinyl (addition) polymerization of the formed cycloadducts in the presence of ([(η3-C3H5)PdCl]2/PCy3/Na+[B(3,5-(CF3)2C6H3)4]− catalyst. The obtained polymers display low-fraction free volume, stable gas permeability over time, and possess a unique feature for the glassy polymers—solubility controlled permeation of hydrocarbons and enhanced C4H10/CH4 selectivity.

© 2019 British Society for Neuroendocrinology The growth hormone secretagogue receptor (GHSR) is a G protein-coupled receptor that is highly expressed in the central nervous system. GHSR acts as a receptor for ghrelin and for liver-expressed antimicrobial peptide 2 (LEAP2), which blocks ghrelin-evoked activity. GHSR also displays ligand-independent activity, including a high constitutive activity that signals in the absence of ghrelin and is reduced by LEAP2. GHSR activity modulates a variety of food intake-related behaviours, including binge eating. Previously, we reported that GHSR-deficient mice daily and time-limited exposed to a high-fat (HF) diet display an attenuated binge-like HF intake compared to wild-type mice. In the present study, we aimed to determine whether ligand-independent GHSR activity affects binge-like HF intake in a 4-day binge-like eating protocol. We found that plasma levels of ghrelin and LEAP2 were not modified in mice exposed to this binge-like eating protocol. Moreover, systemic administration of ghrelin or LEAP2 did not alter HF intake in our experimental conditions. Interestingly, we found that central administration of LEAP2 or K-(D-1-Nal)-FwLL-NH2, which are both blockers of constitutive GHSR activity, reduced binge-like HF intake, whereas central administration of ghrelin or the ghrelin-evoked GHSR activity blockers [D-Lys3]-GHRP-6 and JMV2959 did not modify binge-like HF intake. Taken together, current data indicate that GHSR activity in the brain affects binge-like HF intake in mice independently of plasma levels of ghrelin and LEAP2.

© 2019 Special Care Dentistry Association and Wiley Periodicals, Inc. Aims: This study aimed to investigate the morphology of the palate, palatal rugae pattern, and dental arch form in patients with schizophrenia. Methods and results: An observational case-control study was designed following the STROBE statement and checklist. The sample consisted of 132 patients (39 diagnosed with schizophrenia and 93 controls). Dental casts of the patients were classified based on the pattern of their palatal rugae, their dental arch form, and the area of their palate. The palatal rugae in patients with schizophrenia had a more random distribution and shape compared to the control group (P =.027). Oval dental arches were the most prevalent in both groups (P =.473). The palate area was slightly larger in the control group (3.2318 ± 0.549 mm2) compared with the group of patients with schizophrenia (3.060 ± 0.470 mm2) (P =.090). Conclusion: Palatal rugae pattern may feature as a potential minor physical anomaly for schizophrenia. Additional studies with alternative sampling and classification systems are necessary to understand this finding and its applications in practice.

© 2019 by the authors. Licensee MDPI, Basel, Switzerland. Ovarian cancer is fifth in the rankings of cancer deaths among women, and accounts for more deaths than any other gynecological malignancy. Despite some improvement in overall-(OS) and progression-free survival (PFS) following surgery and first-line chemotherapy, there is a need for development of novel and more effective therapeutic strategies. In this mini review, we provide a summary of the current landscape of the clinical use of tyrosine kinase inhibitors (TKIs) and mechanistic target of rapamycin (mTOR) inhibitors in ovarian cancer. Emerging data from phase I and II trials reveals that a combinatorial treatment that includes TKIs and chemotherapy agents seems promising in terms of PFS despite some adverse effects recorded; whereas the use of mTOR inhibitors seems less effective. There is a need for further research into the inhibition of multiple signaling pathways in ovarian cancer and progression to phase III trials for drugs that seem most promising.

Sequential courses of anticancer target therapy lead to selection of drug-resistant cells, which results in continuous decrease of clinical response. Here we present a new approach for predicting effective combinations of target drugs, which act in a synergistic manner. Synergistic combinations of drugs may prevent or postpone acquired resistance, thus increasing treatment efficiency. We cultured human ovarian carcinoma SKOV-3 and neuroblastoma NGP-127 cancer cell lines in the presence of Tyrosine Kinase Inhibitors (Pazopanib, Sorafenib, and Sunitinib) and Rapalogues (Temsirolimus and Everolimus) for four months and obtained cell lines demonstrating increased drug resistance. We investigated gene expression profiles of intact and resistant cells by microarrays and analyzed alterations in 378 cancer-related signaling pathways using the bioinformatical platform Oncobox. This revealed numerous pathways linked with development of drug resistant phenotypes. Our approach is based on targeting proteins involved in as many as possible signaling pathways upregulated in resistant cells. We tested 13 combinations of drugs and/or selective inhibitors predicted by Oncobox and 10 random combinations. Synergy scores for Oncobox predictions were significantly higher than for randomly selected drug combinations. Thus, the proposed approach significantly outperforms random selection of drugs and can be adopted to enhance discovery of new synergistic combinations of anticancer target drugs.

© 2017 Elsevier B.V. Two series of palladium(II) and platinum(II) complexes featuring esters of tetrazol-1-yl and tetrazol-5-ylacetic acids {trans-[PdCl2L2] and trans-[PtCl2L2], L = 5-methyl-1H-tetrazol-1-ylacetic acid and its ethyl, butyl, isobutyl esters (1–5); 2-R-2H-tetrazol-5-ylacetic acid and its ethyl esters, R = tBu, CH2CH2OH (6–10)} were synthesized and their binding to calf-thymus DNA (CT DNA) and bovine serum albumin (BSA) were studied by means of experimental (CD, UV, viscometry, fluorometric and electrophoretic techniques) and theoretical methods. According to the spectrophotometric data, the interaction of the metal complexes with CT DNA is observed. The significant increase of melting point of CT DNA in the presence of the metal complexes (ΔTm = 8–13 °C) indicates strong stabilization of the DNA helix. Electrophoretic studies demonstrate the ability of the metal complexes to interact with pBR322 plasmid DNA and to change its mobility. According to the data of the fluorescence quenching technique, binding with constants (Kbin) of Pd(II) complexes with BSA are in the range 0.83–4.12 × 105 L M−1. The molecular docking studies show the minor groove binding behavior of tetrazole-containing palladium(II) and platinum(II) complexes to DNA (ΔGbinding. −5.56 − −6.12 kcal/mol) and effective binding to BSA via the favored binding site Trp213 (ΔGbinding −7.2 − −7.56 kcal/mol). The complex trans-[PtCl2(2-tert-butyl-tetrazol-5-ylacetic acid)2] exhibited noticeable antiproliferative activity in two human cancer cell lines with IC50 values of 11.40 µM in HT-29 cells and 11.02 µM in MDA-MB-231 cell line.

© 2018, Dynasty Publishing House. All rights resvered. Abnormal uterine bleeding (AUB) is a collective term uniting various disorders of the menstrual cycle of structural and nonstructural genesis. The causes of AUB are united in the acronym PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy and hyperplasia, Coagulopathy, Ovulatory dysfunction, Endometrial, Iatrogenic, Not otherwise classified). Not infrequently, AUB (PALM), especially in case of associated severe menstrual bleeding, is accompanied by the development of iron-deficiency anaemia (IDA), the basic pathogenetic therapy for which is administration of iron preparations (IP). The choice of an IP should be guided not by the total amount of iron compounds, but by the amounts of elemental iron. A medical practitioner has two groups of IP at his or her disposal – iron salts (IS) and iron-containing complexes (ICC). A comparative analysis of these groups of IP proves the effectiveness of ICC: absence of the impact of food and medication on absorption, slow absorption rate, rapid elimination from blood serum to reserves, absence of oxidative stress, a comparatively rare frequency of side effects on the part of the gastrointestinal tract. Since in female patients with AUB IDA is conditioned by continuing iron losses that exceed the amount of dietary iron intake, administration of IP is obligatory. Additionally, not only the effectiveness but also the safety of an iron-polymaltose complex should be taken into consideration. The good tolerance of Maltofer and a convenient schedule of its dosing ensure a high compliance of patients to therapy.

© N.N. IVANETS E.N. EFREMOVA, 2018. Objective. To explore psychopathological features of affective disorders in the structure of schizotypal disorder. Material and methods. The study included 102 patients with schizotypal disorder, aged from 18 to 60 years. Assessment was done using clinical/ psychopathological method and psychometric scales — Calgary depression scale in patients with schizophrenia (CDSS), General Clinical Impression scale (CGI), Yang’s mania scale (YMRS). Results and conclusion. Affective disorders are noted in the majority of inpatients with schizotypal disorder. They are represented by depressive disorders of variable severity, and mixed depressive states. A group of patients with schizotypal disorder was identified in whom the symptoms of the affective disorder constituted the main clinical picture of the disease, whereas concomitant neurosis-like disorders were formed solely during the exacerbation of depression, correlated with its severity and reduced on antidepressant therapy along with depressive symptoms. Observed reversibility of productive disorders allowed us to consider the dynamic of these states as similar to the atypical affective phase, and the natural course of the disorder as close to the paroxysmal type in the form of distinct depressive phases. In patients with persistent neurosis-like disorders, affective disorders accompanied axial symptoms of the disease and made a large impact on the structure of the exacerbation of the endogenous process. A reduction of depressive symptoms in these patients was accompanied by a decrease in the intensity of axial symptoms of the disease, however the complete reduction of axial symptoms and remission was not observed.

© 2018, Media Sphera Publishing Group. All rights reserved. Objective. An analysis of typical medical errors in the diagnosis and treatment of compression neuropathy of the median nerve at the level of the wrist (carpal tunnel syndrome - CTS). Material and methods. Previous diagnoses and treatment of 85 patients with CTS (14 men and 71 women), aged from 36 to 84 years (middle age 62±10.6 years), who underwent surgery in our clinics were evaluated. Results. The wrong diagnosis was made in most of patients (60%). The osteochondrosi s of cervical spine (45.8%) and diabetic polyneuropathy (5.8%) were the most common mistaken diagnoses. Proper neurophysiological measurements using the Phalen’s test and Tinel’s sign were not performed in the majority of patients. Magnetic resonance imaging (MRI) of the cervical spine was often unreasonably made, the electroneuromyography was not used. Nonsteroidal anti-inflammatory drugs (NSAIDs), vitamin B group were improperly prescribed to the patients diagnosed with CTS. Local corticosteroids injections were not prescribed to most of patients, immobilization of the wrist was not recommended at the early stage of disease and decompressive surgery at the advanced stage of disease. Clinical observation of the patient with long period of misdiagnosing is presented. Despite the long-standing history of CTS, surgical decompression led to regression of symptoms and complete professional rehabilitation. Conclusion. It is necessary to inform physicians about manifestations, diagnostic criteria and effective methods of treatment of CTS.

© Ima-Press Publishing House. All rights reserved. Objective: to investigate the short- and long-term results of surgical median nerve decompression via classical and minimally invasive approaches in patients with carpal tunnel syndrome (CTS), as well as factors that influence surgical outcomes. Patients and methods. The investigation enrolled 70 patients (13 men and 57 women) aged 36 to 84 years (mean age, 62±10.8 years) who had undergone median nerve decompression. Surgery was performed in the classical way in 35 patients (Group 1) and via a minimally invasive access in the remaining 35 patients (Group 2). The efficiency of treatment was evaluated using the Boston Carpal Tunnel Questionnaire (BCTQ) and a visual analog scale for pain before and 1, 3, 6, and 12 months after surgery, as well as from patient satisfaction with surgical outcomes. Results. No complications of surgical treatment were detected. There was a marked reduction in pain and other neuropathic disorders just 1 month after surgery and a substantial hand functional improvement following 6 months. After 12 months, in Group 1, the mean BCTQ Symptom Severity Scale and Functional Deficit Scale scores decreased from 2.76 to 1.15 (p≤0.01) and from 2.72 to 1.24 (p≤0.01), respectively; in Group 2, these dropped from 2.86 to 1.14 (p≤0.01) and from 2.95 to 1.24 (p≤0.01), respectively. Complete recovery from sensory problems occurred in 24 (69%) patients in Group 1 and in 25 (71%) patients in Group 2; their partial recovery was observed in 11 (31%) and 10 (29%) patients in these groups, respectively. One 1 month following decompression, the patients in Group 1 had more severe pain syndrome than those in Group 2; these differences became statistically insignificant after 6 months. The patients were found to be highly satisfied with surgical treatment. Permanent numbness, subjective weakness, thenar muscle atrophy, stage III CTS, and diabetes mellitus (DM) were predictors for less pronounced improvement in BCTQ scores after surgical treatment (p<0.05). The paper describes a clinical case that achieved full postoperative occupational and home rehabilitation. Conclusion. The patients with CTS were observed to have a marked reduction in pain and other neuropathic disorders just one month after surgical decompression and a substantial hand functional improvement following 6 months. The benefit from a minimally invasive access is less severe pain syndrome at 1 month after surgery. The predictors of less successful results of surgery are age (the older the patient is, the greater likelihood of having a worse result), permanent numbness, subjective hand weakness, thenar muscle atrophy, DM, and stage III CTS.

AIM: To evaluate the efficacy and safety of zonisamide as an add-on therapy in structural focal epilepsy in children with cerebral palsy (CP). MATERIAL AND METHODS: Sixty-four patients (36 boys and 28 girls) with spastic CP and structural focal epilepsy with refractory seizures were followed up. Patients received zonisamide in a dose of 6-8.8 mg/kg/day for ≥6 months. Treatment efficacy was assessed by the reduction of seizures depending on CP form, type of epileptic seizures, combination of zonisamide with other drugs and adverse-effects. RESULTS AND CONCLUSION: A reduction of seizures by ≥50% was identified in 60.9% of children, 10.9% showed a better recovery. The best efficacy (35.9%) was demonstrated in the treatment of generalized seizures with focal onset and in the combination with levetiracetam (35.9%). Adverse effects of mild to moderate severity were noted in 26.5% of children. The treatment was discontinued in 7.8%. Therefore, zonisamide is an effective treatment for refractory structural focal epilepsy in children with CP and comorbid pathology, which reduces the frequency of seizures without severe side-effects.

© 2018, Media Sphera Publishing Group. All rights reserved. Delayed facial palsy is a complication developing 3 or more days after surgery. The etiology and pathogenesis of this condition has not been fully explored, and there are no treatment standards for it. As in the case of Bell’s paralysis, glucocorticosteroids (GCSs) are currently used to treat delayed facial palsy. However, patients with contraindications to GCSs need new therapy modalities. Aim - we aimed to evaluate the efficacy and safety of botulinum therapy in patients with delayed facial palsy after neurosurgical interventions. Material and methods. We examined 33 patients with delayed facial palsy developed 3 or more days after resection of vestibular schwannoma. The main group included 18 patients with contraindications to GCSs who received injections of botulinum toxin A (BTA) into the facial muscles of the healthy side for muscle relaxation. The comparison group consisted of 15 patients who received a course of prednisolone (1 mg/kg/day) for 5-7 days. The efficacy of treatment was assessed using the House-Brackmann scale and Clinical Global Impression Scale. The follow-up period after therapy was 3 months. Results. Delayed facial palsy was more common in the following cases: the facial nerve was located near the antero-inferior tumor pole; the tumor was adherent to the facial nerve; the tumor extended in the oral direction; the tumor had with unclear borders and was 11 to 30 mm in size. In most patients of both groups, facial muscle palsy developed more than 11 days after surgery. Treatment both in the main and control groups resulted in a significant improvement: complete regression of the facial asymmetry in patients of the main group and comparison groups 3 months after treatment onset was 83.3 and 93.3% (House-Brackmann scale), respectively. Conclusion. Botulinum therapy may be recommended for patients with delayed facial palsy developed after vestibular schwannoma resection, who have contraindications to GCSs.
