Comparison of Pelvic Floor Muscle Training With Connective Tissue Massage to Pelvic Floor Muscle Training Alone in Women With Overactive Bladder: A Randomized Controlled Study

ObjectiveThe purpose of this study was to compare the effects of a 6-week program of pelvic floor muscle training (PFMT) plus connective tissue massage (CTM) to PFMT alone in women with overactive bladder (OAB) symptoms on those symptoms, pelvic floor muscle strength, and quality of life.MethodsThirty-four participants were randomly divided into PFMT+CTM (n = 17) and PFMT (n = 17) groups. PFMT was applied every day and CTM was applied 3 days a week for 6 weeks. Before treatment, at week 3, and after treatment (week 6), we assessed pelvic floor muscle strength (with a perineometer), bladder symptoms (with a urine diary), OAB symptom severity (with the 8-item Overactive Bladder Questionnaire [OAB-V8]), urgency (with the Patient Perception of Intensity of Urgency Scale [PPIUS]), and quality of life (with King's Health Questionnaire [KHQ]). The Mann–Whitney U test, χ² test, Friedman test, and Dunn multiple comparison test were used for analysis.ResultsIn both groups, pelvic floor muscle strength increased, whereas OAB symptoms and PPIUS and KHQ scores decreased after treatment (P < .05). Although the OAB-V8, PPIUS, and KHQ scores decreased at week 3, frequency, OAB-V8, and PPIUS scores, in addition to some parameters of the KHQ, decreased after treatment in the PFMT+CTM group compared to the PFMT group (P < .05).ConclusionCompared to PFMT alone, PFMT+CTM achieved superior outcomes in reducing OAB symptoms in the early and late periods.     

Is multiple sclerosis a risk factor for atherosclerosis?

BackgroundMultiple sclerosis (MS) is an inflammatory demyelinating disease of the central nervous system. We aimed to discuss possible predisposing factors to atherosclerosis such as carotid intima-media thickness (CIMT) and high-sensitivity C-reactive protein (Hs-CRP) levels in MS.MethodsThirty-five ambulatory patients with relapsing-remitting MS (RRMS) (22 females and 13 males) and 34 healthy controls (21 females and 13 males) with similar demographic variables were included. Blood cell counts, cholesterol levels, vitamin D and B12, Hs-CRP levels, body mass index (BMI), history of smoking, and CIMT of both groups, Expanded Disability Status Scale (EDSS) scores, and disease duration of patients were recorded. Patients with a history of other vascular diseases such as hypertension, diabetes mellitus, peripheral artery disease, and acute relapses were excluded.ResultsSixty-nine participants were included. The mean age of the study population was 35.8 ± 7.1 years. Right CIMT was significantly greater in the patient population (P < 0.001). Spearman's correlation coefficient between age and right CIMT was r = 0.41, P = 0.01. When we compared the Hs-CRP with a cut-off value of ≤ 3, the right, left, and mean CIMT levels were not statistically significant (P = 0.17; P = 0.22; P = 0.15). The mean serum vitamin D levels were higher in the patient group and this was statistically significant (P < 0.001). The statistically significant factors identified with univariate analysis with P < 0.2 were further entered into multivariate modelling.ConclusionCIMT seems to be affected in patients with MS by means of the disease itself and age. Thus, CIMT might reflect the predisposition to subclinical atherosclerosis more than Hs-CRP. Further investigation in a large MS population is still needed.     

Effects of Forward Model Errors on EEG Source Localization

Subject-specific four-layer boundary element method (BEM) electrical forward head models for four participants, generated from magnetic resonance (MR) head images using NFT (www.sccn.ucsd.edu/wiki/NFT), were used to simulate electroencephalographic (EEG) scalp potentials at 256 recorded electrode positions produced by single current dipoles of a 3-D grid in brain space. Locations of these dipoles were then estimated using gradient descent within five template head models fit to the electrode positions. These were: a spherical model, three-layer and four-layer BEM head models based on the Montreal Neurological Institute (MNI) template head image, and these BEM models warped to the recorded electrode positions. Smallest localization errors (4.1–6.2 mm, medians) were obtained using the electrode-position warped four-layer BEM models, with largest localization errors (~20 mm) for most basal brain locations. When we increased the brain-to-skull conductivity ratio assumed in the template model scalp projections from the simulated value (25:1) to a higher value (80:1) used in earlier studies, the estimated dipole locations moved outwards (12.4 mm, median). We also investigated the effects of errors in co-registering the electrode positions, of reducing electrode counts, and of adding a fifth, isotropic white matter layer to one individual head model. Results show that when individual subject MR head images are not available to construct subject-specific head models, accurate EEG source localization should employ a four- or five-layer BEM template head model incorporating an accurate skull conductivity estimate and warped to 64 or more accurately 3-D measured and co-registered electrode positions.     

Comparison of Rosco Neo-Sensitabs with Oxoid paper disks in EUCAST disk diffusion antimicrobial susceptibility testing on Mueller–Hinton agar

This study compared Neo-Sensitabs with Oxoid paper disks using the European Committee on Antimicrobial Susceptibility Testing (EUCAST) disk diffusion antimicrobial susceptibility test on Mueller–Hinton agar. The EUCAST-recommended quality control strains (Escherichia coli ATCC 25922, Pseudomonas aeruginosa ATCC 27853, Staphylococcus aureus ATCC 29213 and Enterococcus faecalis ATCC 29212) (Part I) and clinical isolates (Part II) were investigated. In Part I of the study, 27 combinations of antimicrobial agents were tested on four quality control strains repeatedly up to 60 times and zone diameters of tablets and disks were compared. In Part II of the study, 351 clinical isolates were included to cover a broad range of species, as well as resistance mechanisms. In Part I, four major deviations (>1 mm outside quality control ranges) were observed with Neo-Sensitabs. In one case with P. aeruginosa ATCC 27853 (meropenem), there was a corresponding major deviation (2 mm) with the Oxoid disk. The three remaining major deviations with Neo-Sensitabs were observed with meropenem (2 mm) in E. coli ATCC 25922 and with ciprofloxacin (2 mm) and gentamicin (3 mm) in P. aeruginosa ATCC 27853. For Oxoid disks, there were only minor deviations (=1 mm outside quality control ranges) in these three cases. In Part II, there were six discrepancies, susceptible versus resistant, in 3,533 comparisons between the two methods with the clinical isolates. The Rosco Neo-Sensitabs appear to be a possible alternative to Oxoid paper disks for EUCAST disk diffusion antimicrobial susceptibility testing on Mueller–Hinton agar.
