    OBJECTIVE--To compare the clinical efficacy, patient satisfaction, and cost of three specialist treatments for depressive illness with routine care by general practitioners in primary care. DESIGN--Prospective, randomised allocation to amitriptyline prescribed by a psychiatrist, cognitive behaviour therapy from a clinical psychologist, counselling and case work by a social worker, or routine care by a general practitioner. SUBJECTS AND SETTING--121 patients aged between 18 and 65 years suffering depressive illness (without psychotic features) meeting the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Third Edition for major depressive episode in 14 primary care practices in southern Edinburgh. MAIN OUTCOME MEASURES--Standard observer rating of depression at outset and after four and 16 weeks. Numbers of patients recovered at four and 16 weeks. Total length and cost of therapist contact. Structured evaluation of treatment by patients at 16 weeks. RESULTS--Marked improvement in depressive symptoms occurred in all treatment groups over 16 weeks. Any clinical advantages of specialist treatments over routine general practitioner care were small, but specialist treatment involved at least four times as much therapist contact and cost at least twice as much as routine general practitioner care. Psychological treatments, especially social work counselling, were most positively evaluated by patients. CONCLUSIONS--The additional costs associated with specialist treatments of new episodes of mild to moderate depressive illness presenting in primary care were not commensurate with their clinical superiority over routine general practitioner care. A proper cost-benefit analysis requires information about the ability of specialist treatment to prevent future episodes of depression. PMID:1392754

    The interpretation of neurobehavioral change over time requires knowledge of the test-retest characteristics of the measures. Without this information it is not possible to distinguish a true change (i.e., one reflecting the occurrence or resolution of an intervening process) from that occurring on the basis of chance or systematic bias. We tested a group of 72 healthy young to middle aged adults twice over a 12-to-16-week interval in order to observe the change in scores over time when there was no known intervention. The test battery consisted of seven commonly used cognitive measures and the Profile of Mood States (POMS). Test-retest regression equations were calculated for each measure using initial performance, age, education, and a measure of general intellectual function (Wonderlic Personnel Test) as regressors. Test-retest correlations ranged from .39 (POMS Fatigue) to .89 (Digit Symbol). Cognitive measures generally yielded higher correlations than did the POMS. Univariate regressions based only on initial performance adequately predicted retest performance for the majority of measures. Age and education had a relatively minor influence. Practice effects and regression to the mean were common. These test-retest regression equations can be used to predict retest scores when there has been no known intervention. They can also be used to generate statistical statements regarding the significance of change in an individual's performance over a 12-to-16-week interval. PMID:11459111

    The purpose of this study was to examine the effects of training with intermittent breath holding (IBH) on respiratory parameters, arterial oxygen saturation (SpO2) and performance. Twenty-eight fin-swimming athletes were randomly divided into two groups and followed the same training for 16 weeks. About 40% of the distance of each session was performed with self-selected breathing frequency (SBF group) or IBH (IBH group). Performance time of 50 and 400 m at maximum intensity was recorded and forced expired volume in 1 s (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and SpO2 were measured before and after the 50 m test at baseline and post-training. Post-training, the respiratory parameters were increased in the IBH but remained unchanged in the SBF group (FEV1: 17 ±15% vs. −1 ±11%; FVC: 22 ±13% vs. 1 ±10%; PEF: 9 ±14% vs. −4 ±15%; p<0.05). Pre compared to post-training SpO2 was unchanged at baseline and decreased post-training following the 50 m test in both groups (p<0.05). The reduction was higher in the IBH compared to the SBF group (p<0.05). Performance in the 50 and 400 m tests improved in both groups, however, the improvement was greater in the IBH compared to the SBF group in both 50 and 400 m tests (p<0.05). The use of IBH is likely to enhance the load on the respiratory muscles, thus, contributing to improvement of the respiratory parameters. Decreased SpO2 after IBH is likely due to adaptation to hypoventilation. IBH favours performance improvement at 50 and 400 m fin-swimming. PMID:26839609

    Effective treatment of diabetic sensorimotor polyneuropathy remains a challenge. To assess the efficacy and safety of α-lipoic acid (ALA) over 20 weeks, we conducted a multicenter randomized withdrawal open-label study, in which 45 patients with type 2 diabetes and symptomatic polyneuropathy were initially treated with ALA (600 mg tid) for 4 weeks (phase 1). Subsequently, responders were randomized to receive ALA (600 mg qd; n = 16) or to ALA withdrawal (n = 17) for 16 weeks (phase 2). During phase 1, the Total Symptom Score (TSS) decreased from 8.9 ± 1.8 points to 3.46 ± 2.0 points. During phase 2, TSS improved from 3.7 ± 1.9 points to 2.5 ± 2.5 points in the ALA treated group (p < 0.05) and remained unchanged in the ALA withdrawal group. The use of analgesic rescue medication was higher in the ALA withdrawal group than ALA treated group (p < 0.05). In conclusion, in type 2 diabetic patients with symptomatic polyneuropathy who responded to initial 4-week high-dose (600 mg tid) administration of ALA, subsequent treatment with ALA (600 mg qd) over 16 weeks improved neuropathic symptoms, whereas ALA withdrawal was associated with a higher use of rescue analgesic drugs.

    A prospective, single-centre, randomized controlled study was performed to evaluate the effectiveness of Graftjacket, a human acellular regenerative tissue matrix as a treatment option for chronic non healing lower extremity wounds. Twenty-eight diabetic patients with full-thickness wounds that had been present for at least 6 weeks were treated with sharp debridement and randomized to a single application of Graftjacket tissue matrix plus mineral oil-soaked fluff compression dressing or to a control treatment of wound gel with gauze dressings. All patients were seen weekly. By week 16, 12 of 14 patients treated with Graftjacket tissue matrix demonstrated complete wound closure compared with 4 of 14 patients in the control group. Patients treated with Graftjacket tissue matrix showed a statistically significant higher percentage of wound healing with respect to wound area, and clinically significant differences in wound depth and wound volume. This comparison is not performed to demonstrate that the application of the Grafjacket is more effective than sharp debridement. This study is done to help assign a role to the use of Graftjacket matrix in lower extremity wound care. PMID:16984575

    Background A growing body of evidence has linked vitamin D deficiency to increased risk of cardiovascular disease. Vitamin D deficiency is also more common in African Americans for whom an increased cardiovascular disease risk exists. This study sought to test the hypothesis that 16 weeks of 60,000 IU monthly supplementation of oral vitamin D3 would improve flow-mediated dilation (FMD) in African Americans, whereas no change would be observed in the placebo group. Methods A randomized, double blind, placebo controlled clinical trial was conducted. Fifty-seven African American adults were randomly assigned to either the placebo group or vitamin D group. Results Following 16 weeks of placebo (n=23; mean age 31±2 years) or 60,000 IU monthly oral vitamin D3 (n=22; mean age 29±2 years), serum concentrations of 25 hydroxyvitamin D increased from 38.2±3.0 nmol/L to 48.7±3.2 nmol/L and 34.3±2.2 nmol/L to 100.9±6.6 nmol/L, respectively. No changes in serum parathyroid hormone, serum calcium, or urine calcium/creatinine were observed following either treatment. Following 16 weeks of treatment, significant improvements in FMD were only observed in the vitamin D group (1.8±1.3%), whereas the placebo group had no change (-1.3±0.6%). Similarly, the vitamin D group exhibited an increase in absolute change in diameter (0.005±0.004 cm) and FMD/shear (0.08±0.04 %/s-1, AUC × 103) following treatment, whereas no change (-0.005±0.002 cm and -0.02±0.02 %/s-1, AUC, respectively) was observed following placebo. Conclusions Supplementation of 60,000 IU monthly oral vitamin D3 (~2000 IU per day) for 16 weeks is effective at improving vascular endothelial function in African American adults. PMID:21311504

    Objective Evaluation of the relationship between canine weight gain from 6 to 15 weeks of age and passive coxofemoral joint (CFJ) laxity at 16 weeks of age. Study Design Longitudinal cohort study. Animals Full- or half-sibling hounds (n = 56). Methods Hounds were weighed weekly from 6 to 15 weeks of age. Individual average daily gain (ADG) was calculated for each week (weekly) and for the study (overall). PennHIP distraction index (DI) was determined for each CFJ at 16 weeks. Mixed effects linear models were evaluated for associations of DI (highest and mean) with 15-week weight and ADGs (actual or normalized). Left and right DIs were compared with a Student’s paired t-test. Significance was set at P < .05. Trends were considered at P < .10. Results Mean (± SD) 16-week DI score and 15-week weight was 0.67 ± 0.16 and 12.5 ± 1.8 kg, respectively. Within animal left and right DIs were not significantly different. There were no significant associations between DI and any of the weight gains evaluated. There was a trend for a negative relationship between normalized 14-week ADG and DI in one statistical model. Conclusions Weight gain from 6 to 15 weeks of age was unrelated to 16-week PennHIP DI in a homogenous canine population with moderate-to-severe CFJ joint laxity. Clinical Relevance Based on our results, ad libitum feeding between 6 and 15 weeks of age does not appear to have an adverse impact on joint laxity at 16 weeks of age as measured by the PennHIP DI.

J Strength Cond Res 30(5): 1416–1424, 2016—Police academies traditionally emphasize the importance of being physically fit. The purpose of this research was to determine cadet baseline physical fitness characteristics and assess effectiveness of a 16-week training program. Sixty-eight cadets (61 men, 7 women) volunteered to have baseline physical fitness characteristics assessed, and 55 cadets (49 men, 6 women) completed further testing at weeks 8 and 16. The testing comprised hand grip (strength), arm crank (upper-body power), 30 seconds Wingate (lower body power), sum of skinfolds and percentage body fat (body composition), 40-yard dash (sprint speed), 1 repetition maximum bench press (strength), T-test (agility), and sit-and-reach (flexibility). In addition, cadets completed standardized state testing (push-ups, sit-ups, vertical jump, and half-mile shuttle run). The training program consisted of 1 hour sessions, 3 d·wk−1, including aerobic, plyometrics, body weight, and resistance exercise. Significant changes were found in agility (p < 0.01), upper-body and lower-body peak power (p ≤ 0.05), sit-ups (p < 0.01), push-ups (p ≤ 0.05) across the first 8 weeks, and in agility (p ≤ 0.05), lower-body peak power (p ≤ 0.05), sit-ups (p < 0.01), push-ups (p ≤ 0.05), half-mile shuttle run (p < 0.01) across the full 16 weeks. However, none of the variables showed significant change across the second half of the program (weeks 8–16). A number of individual parameters of physical fitness showed evidence of improvement in the first 8 weeks, whereas none of the variables showed significant improvement in the second 8 weeks. This suggests modifications could be made to increase overall effectiveness of cadet physical training specifically after the 8-week mark. PMID:26466133

    We examined the effects of 16 weeks of training on diurnal pattern of salivary alpha-amylase (sAA), cortisol, and the ratio of sAA over cortisol (AOC) in 12 national adolescent female tennis players. Stress and recovery were also evaluated using the Recovery-Stress-Questionnaire for Athletes-RESTQ-Sport. Data were collected after a 2-week rest (January, W0), and 4 months after W0 (W16). Subjects collected five saliva samples throughout a day. While all participants displayed the previously shown decrease after awakening in adolescents at W0, they showed a rise in the alpha-amylase awakening response and a higher alpha-amylase activity output (p<0.01) at W16 compared to W0. For the daily rhythm of cortisol we found subjects having a low overall output of salivary cortisol (p<0.01) and a blunted response to awakening at W16. Furthermore, an increase in the ratio AOC at W16, and a negative correlation between this ratio and Sport-specific recovery score. Our findings offer support for the hypothesis that increase of training load during the study period induced asymmetry activation between the two stress systems, in relation to psychological alterations and performance decrease. These results provide encouragement to continue exploring the impact of training program using a psychobiological approach among young athletes in order to prevent fatigue and preserve the health of these athletes.

    We conducted a 16-week double-blind randomized controlled single-center trial to evaluate the safety and efficacy of dermal rice bran supercritical CO2 extract (RB-SCE) in the treatment of androgenic alopecia. Fifty alopecia patients were randomly assigned to the experimental and placebo groups. The experimental group received a dermal application of 0.5% RB-SCE (8 mL/d) to the head skin for 16 weeks while the control group received a dermal application of placebo. Changes in hair count, diameter, and density were evaluated with a Folliscope(®). Patient satisfaction was evaluated via questionnaire and clinical photographs were rated by dermatologists. The results showed that RB-SCE significantly increased hair density and hair diameter in male subjects. Patient satisfaction and the evaluation of photographs by dermatologists also confirmed the effectiveness of RB-SCE in the treatment of alopecia. No adverse reactions related to RB-SCE were reported. Therefore, RB-SCE shows promise for use in functional cosmetics and pharmaceuticals. PMID:26632177

    Background Direct-to-consumer trackers and devices have potential to enhance theory-based physical activity interventions by offering a simple and pleasant way to help participants self-monitor their behavior. A secondary benefit of these devices is the opportunity for investigators to objectively track adherence to physical activity goals across weeks or even months, rather than relying on self-report or a small number of accelerometry wear periods. The use of consumer trackers for continuous monitoring of adherence has considerable potential to enhance physical activity research, but few studies have been published in this rapidly developing area. Objective The objective of the study was to assess the trajectory of physical activity adherence across a 16-week self-monitoring intervention, as measured by the Fitbit tracker. Methods Participants were 25 overweight or obese, postmenopausal women enrolled in the intervention arm of a randomized controlled physical activity intervention trial. Each participant received a 16-week technology-based intervention that used the Fitbit physical activity tracker and website. The overall study goal was 150 minutes/week of moderate to vigorous intensity physical activity (MVPA) and 10,000 steps/day; however, goals were set individually for each participant and updated at Week 4 based on progress. Adherence data were collected by the Fitbit and aggregated by Fitabase. Participants also wore an ActiGraph GT3X+ accelerometer for 7 days prior to the intervention and again during Week 16. Results The median participant logged 10 hours or more/day of Fitbit wear on 95% of the 112 intervention days, with no significant decline in wear over the study period. Participants averaged 7540 (SD 2373) steps/day and 82 minutes/week (SD 43) of accumulated “fairly active” and “very active” minutes during the intervention. At Week 4, 80% (20/25) of women chose to maintain/increase their individual MVPA goal and 72% (18/25) of participants

    BACKGROUND/OBJECTIVES The standard pattern of Brazilian food consumption is based on the combination of rice and beans served together in the main meals. This study assessed the effects of Brazilian-staple calorie-restricted (BS-diet) dietary advice, with brown rice and beans, on metabolic parameters, body composition, and food intake in overweight/obese subjects. SUBJECTS/METHODS Twentyseven subjects were randomly assigned to a conventional-type calorie-restricted diet (CT-diet) (n = 13) or a BS-diet (n = 14). Glucose metabolism, lipid profile, anthropometric and body composition parameters, and food intake were measured before and after 16 weeks. Paired t-tests/Wilcoxon tests were used for comparison of differences from baseline and unpaired t-tests/Mann-Whitney tests were used for comparison of differences between the groups. RESULTS After 16 weeks, both groups showed reductions in weight and waist circumference (P < 0.02), and the BS-diet group showed a decrease in body fat (P = 0.0001), and significant improvement in glucose metabolism (fasting plasma glucose, glucose and insulin areas under the curve, Cederholm index, and HOMA2-%β) (P ≤ 0.04) and lipid profile (cholesterol, triacylglycerol, LDL-c, VLDL-c, and cholesterol/HDL-c ratio) (P ≤ 0.05). In addition, the BS-diet group showed significant improvement in HOMA2-%β, compared to the CT-diet group (P = 0.03). The BS-diet group also showed a significant reduction in energy, lipids, carbohydrate, and cholesterol intake (P ≤ 0.04) and an increase in fiber intake (P ≤ 0.001), while the CT-diet group showed a significant reduction in intake of energy, macronutrients, PUFA, and cholesterol (P ≤ 0.002). CONCLUSIONS These results demonstrate the benefits of the BS-diet on metabolic parameters in obese subjects. PMID:25110561

    The purpose of this study is to compare the efficacy of olanzapine and risperidone for the acute treatment of first-episode schizophrenia patients with cannabis use disorders. This secondary analysis of a previously published study included 49 first-episode patients with a diagnosis of schizophrenia, schizophreniform disorder, or schizoaffective disorder and a co-occurring lifetime diagnosis of cannabis use disorders randomly assigned to treatment with either olanzapine (n=28) or risperidone (n=21) for 16weeks. The olanzapine group did not differ significantly from the risperidone group for initial response rates of positive symptoms, and rates of cannabis use or alcohol use during the study. Positive symptoms and the Scale for Assessment of Negative Symptoms (SANS) global asociality-anhedonia scores improved over time but did not differ between study medications. In both groups, cannabis use during the study was higher in patients who used cannabis within three months of the admission. Thus, our results suggest that olanzapine and risperidone had a similar initial efficacy on psychotic symptoms and substance use in first-episode patients with co-occurring cannabis use disorders. If clinicians are choosing between olanzapine versus risperidone treatment for this population, their decision should be based upon factors other than symptom response and short-term substance misuse.

    Weight loss improves endothelial function in overweight individuals. The effects of weight loss through combined aerobic and resistance training and caloric restriction on in vivo vascular measures and blood markers associated with the regulation of endothelial function have not been comprehensively examined. Therefore, we investigated brachial artery endothelial function and potential regulatory blood markers in twenty overweight women (30.3 ± 2.0 years) who participated in 16 weeks of aerobic (5 d/wk) and resistance training (2 d/wk) (combined: ≥250 kcal/d) and caloric restriction (−500 kcal/d versus requirement). Resting brachial artery flow mediated dilation (FMD) and circulating endothelin-1 (ET-1) and interleukin-6 (IL-6) were assessed at baseline and following the intervention. Relative and absolute FMD increased (before: 4.0 ± 0.5% versus after: 6.9 ± 0.6%, P < 0.05, and before: 0.14 ± 0.02 mm versus after: 0.23 ± 0.02 mm, P < 0.05, resp.), while body mass decreased (before: 86.9 ± 2.4 kg versus after: 81.1 ± 2.4 kg, P < 0.05) following the intervention. There were no changes in either blood marker (IL-6: before: 1.5 ± 0.2 pg/mL versus after: 1.5 ± 0.1 pg/mL, P > 0.05, and ET-1: before: 0.55 ± 0.05 pg/mL versus after: 0.59 ± 0.09 pg/mL, P > 0.05). 16 weeks of combined aerobic/resistance training and diet-induced weight loss improved endothelial function in overweight and obese young women, but this increase was not associated with changes in blood markers of vasoconstriction or inflammation.

    Supplementation with vitamins, minerals and phytonutrients may be beneficial for cognition, especially in older adults. The aim of this study was to assess the effects of multivitamin supplementation in older adults on cognitive function and associated blood biomarkers. In a randomised, double blind, placebo-controlled trial, healthy women (n = 68) and men (n = 48) aged 55–65 years were supplemented daily for 16 weeks with women’s and men’s formula multivitamin supplements. Assessments at baseline and post-supplementation included computerised cognitive tasks and blood biomarkers relevant to cognitive aging. No cognitive improvements were observed after supplementation with either formula; however, several significant improvements were observed in blood biomarkers including increased levels of vitamins B6 and B12 in women and men; reduced C-reactive protein in women; reduced homocysteine and marginally reduced oxidative stress in men; as well as improvements to the lipid profile in men. In healthy older people, multivitamin supplementation improved a number of blood biomarkers that are relevant to cognition, but these biomarker changes were not accompanied by improved cognitive function.

    The perinatal period is a time of high risk for women with unipolar and bipolar mood disorders. We discuss treatment considerations for perinatal mood disorders, including unipolar and bipolar depression as well as postpartum psychosis. We further explore the unique issues faced by women and their families across the full trajectory of the perinatal period from preconception planning through pregnancy and following childbirth. Treatment of perinatal mood disorders requires a collaborative care approach between obstetrics practitioners and mental health providers, to ensure that a thoughtful risk : benefit analysis is conducted. It is vital to consider the risks of the underlying illness versus risks of medication exposure during pregnancy or lactation. When considering medication treatment, attention must be paid to prior medication trials that were most efficacious and best tolerated. Lastly, it is important to assess the impact of individual psychosocial stressors and lifestyle factors on treatment response. PMID:26246794

    In 145 patients with unstable angina (UA) there was analized an efficiency of a drug therapy at different types of heliogeophysical activity (HA) during the 23th solar cycle. 83 patients were examined at the period of a lower HA (Kp-index 16,19±0,18), and 62 patients - at the period of a higher HA (Kp-index 17,25±0,21, p<0,05). Baseline severity of patients' condition with UA at the moment of hospitalization at the studied periods did not differ, but the effectiveness of the therapy depended on the period of HA. At the period of a higher HA antianginal effect was stronger than at the lower period of HA (2,27±0,16 points and 1,75±0,12 points, p<0,05), and the need in nitroglycerin on the background of a drug therapy disappeared for 5-7 days quicker than at the period of a lower HA. Maximal hypotensive effect at a higher HA was achieved quicker - on the 3rd day of the treatment, and at a lower HA - only up to hospital discharge (p<0,05). Blood viscosity did not normalize in both of the studied periods, but in small vessels there was noted a decrease of a BV (p<0,05). So, at a higher HA the effectiveness of a drug therapy in patients with UA is higher than at the period of a lower HA.

    Limited contaminant bioavailability at concentrations above the required cleanup level reduces biodegradation rate and renders solid-phase bioremediation more cost effective than complete treatment in a bioslurry reactor. Slurrying followed by solid-phase bioremediation combines the advantages and minimizes the weaknesses of each treatment method when used alone. Periodic aeration during solid-phase bioremediation has the potential to lower treatment costs relative to continuous aeration. A biological treatment system consisting of slurrying followed by periodic aeration in solid-phase sequencing batch reactors (SP-SBRs) was developed and tested in the laboratory using a silty loam contaminated predominantly with the plasticizer bis(2-ethylhexyl)phthalate (BEHP) or (DEHP) and a silty clay loam contaminated with diesel fuel. The first experiment evaluated the effect of water content and mixing time during slurrying on subsequent treatment in continuously aerated solid-phase bioreactors. The second experiment compared treatment of slurried soil in SP-SBRs using three different periodic aeration strategies with continuous aeration.

    Chlorine dioxide was injected into the water intakes at two power plants in Illinois and one in Indiana in an effort to eradicate the existing population of zebra mussels and mitigate further settlement in station river water cooling systems. Results of the treatments at Illinois Power Company`s Wood River Station on the Mississippi River, Central Illinois Public Service`s Meredosia Station on the Illinois River, and SI Energy`s Gallagher Station on the Ohio River are reported. Treatments were performed on a turnkey basis, with three treatments performed at Meredosia Station in 1994, six treatments performed at Wood River Station between July 1993 and September 1994, and 2 treatments performed at Gallagher Station in 1994. For each treatment, a contractor installed and operated a portable chlorine dioxide generator, monitored water quality and oxidant levels, and provided and monitored bioboxes containing test mussels. Results of the treatments were very favorable, indicating a good potential for periodic treatments with chlorine dioxide to control zebra mussel infestations in the raw water systems of power plants and other industrial facilities. Some difficulties with the chlorine dioxide generation system and cold temperature effects reduced the treatment effectiveness, particularly the second treatment at Gallagher Station. Average induced mortalities ranged from 70 to 100% at Wood River, 87 to 92% at Meredosia, and 30 to 100% at Gallagher for native mussels. Dechlorination successfully kept total oxidant residual levels at or below 0.05 ppM during all treatments at all stations.

    Abstract Objective The purpose of this study was to evaluate atomoxetine treatment effects in attention-deficit/hyperactivity disorder (ADHD-only), attention-deficit/hyperactivity disorder with comorbid dyslexia (ADHD+D), or dyslexia only on ADHD core symptoms and on sluggish cognitive tempo (SCT), working memory, life performance, and self-concept. Methods Children and adolescents (10–16 years of age) with ADHD+D (n=124), dyslexia-only (n=58), or ADHD-only (n=27) received atomoxetine (1.0–1.4 mg/kg/day) or placebo (ADHD-only subjects received atomoxetine) in a 16 week, acute, randomized, double-blind trial with a 16 week, open-label extension phase (atomoxetine treatment only). Changes from baseline were assessed to weeks 16 and 32 in ADHD Rating Scale-IV-Parent-Version:Investigator-Administered and Scored (ADHDRS-IV-Parent:Inv); ADHD Rating Scale-IV-Teacher-Version (ADHDRS-IV-Teacher-Version); Life Participation Scale—Child- or Parent-Rated Version (LPS); Kiddie-Sluggish Cognitive Tempo (K-SCT) Interview; Multidimensional Self Concept Scale (MSCS); and Working Memory Test Battery for Children (WMTB-C). Results At week 16, atomoxetine treatment resulted in significant (p<0.05) improvement from baseline in subjects with ADHD+D versus placebo on ADHDRS-IV-Parent:Inv Total (primary outcome) and subscales, ADHDRS-IV-Teacher-Version Inattentive subscale, K-SCT Interview Parent and Teacher subscales, and WMTB-C Central Executive component scores; in subjects with Dyslexia-only, atomoxetine versus placebo significantly improved K-SCT Youth subscale scores from baseline. At Week 32, atomoxetine-treated ADHD+D subjects significantly improved from baseline on all measures except MSCS Family subscale and WMTB-C Central Executive and Visuo-spatial Sketchpad component scores. The atomoxetine-treated dyslexia-only subjects significantly improved from baseline to week 32 on ADHDRS-IV-Parent:Inv Inattentive subscale, K-SCT Parent and Teacher subscales, and WMTB

  7. The effect of gold kiwifruit consumed with an iron fortified breakfast cereal meal on iron status in women with low iron stores: A 16 week randomised controlled intervention study

    PubMed Central

    2010-01-01

    Background Dietary treatment is often recommended as the first line of treatment for women with mild iron deficiency. Although it is well established that ascorbic acid enhances iron absorption, it is less clear whether the consumption of ascorbic acid rich foods (such as kiwifruit) with meals fortified with iron improves iron status. The aim of this study is to investigate whether the consumption of ZESPRI® GOLD kiwifruit (a fruit high in ascorbic acid and carotenoids) with an iron fortified breakfast cereal meal increases iron status in women with low iron stores. Methods/Design Eighty nine healthy women aged 18-44 years with low iron stores (serum ferritin (SF) ≤ 25 μg/L, haemoglobin (Hb) ≥ 115 g/L) living in Auckland, New Zealand were randomised to receive an iron fortified breakfast cereal (16 mg iron per serve) and either two ZESPRI® GOLD kiwifruit or a banana (low ascorbic acid and carotenoid content) to eat at breakfast time every day for 16 weeks. Iron status (SF, Hb, C-reactive protein (CRP) and soluble transferrin receptor (sTfR)), ascorbic acid and carotenoid status were measured at baseline and after 16 weeks. Anthropometric measures, dietary intake, physical activity and blood loss were measured before and after the 16 week intervention. Discussion This randomised controlled intervention study will be the first study to investigate the effect of a dietary based intervention of an iron fortified breakfast cereal meal combined with an ascorbic acid and carotenoid rich fruit on improving iron status in women with low iron stores.

    It is unclear whether combined leg and arm high-intensity interval training (HIIT) improves fitness and morphological characteristics equal to those of leg-based HIIT programs. The aim of this study was to compare the effects of HIIT using leg-cycling (LC) and arm-cranking (AC) ergometers with an HIIT program using only LC. Effects on aerobic capacity and skeletal muscle were analyzed. Twelve healthy male subjects were assigned into two groups. One performed LC-HIIT (n=7) and the other LC- and AC-HIIT (n=5) twice weekly for 16 weeks. The training programs consisted of eight to 12 sets of >90% VO2 (the oxygen uptake that can be utilized in one minute) peak for 60 seconds with a 60-second active rest period. VO2 peak, watt peak, and heart rate were measured during an LC incremental exercise test. The cross-sectional area (CSA) of trunk and thigh muscles as well as bone-free lean body mass were measured using magnetic resonance imaging and dual-energy X-ray absorptiometry. The watt peak increased from baseline in both the LC (23%±38%; P<0.05) and the LC–AC groups (11%±9%; P<0.05). The CSA of the quadriceps femoris muscles also increased from baseline in both the LC (11%±4%; P<0.05) and the LC–AC groups (5%±5%; P<0.05). In contrast, increases were observed in the CSA of musculus psoas major (9%±11%) and musculus anterolateral abdominal (7%±4%) only in the LC–AC group. These results suggest that a combined LC- and AC-HIIT program improves aerobic capacity and muscle hypertrophy in both leg and trunk muscles. PMID:25395872

    The nervous system is vulnerable to perturbations during specific developmental periods. Insults during such susceptible time windows can have long-term consequences, including the development of neurological diseases such as epilepsy. Here we report that a pharmacological intervention timed during a vulnerable neonatal period of cortical development prevents pathology in a genetic epilepsy model. By using mice with dysfunctional Kv7 voltage-gated K(+) channels, which are mutated in human neonatal epilepsy syndromes, we demonstrate the safety and efficacy of the sodium-potassium-chloride cotransporter NKCC1 antagonist bumetanide, which was administered during the first two postnatal weeks. In Kv7 current-deficient mice, which normally display epilepsy, hyperactivity and stereotypies as adults, transient bumetanide treatment normalized neonatal in vivo cortical network and hippocampal neuronal activity, prevented structural damage in the hippocampus and restored wild-type adult behavioral phenotypes. Furthermore, bumetanide treatment did not adversely affect control mice. These results suggest that in individuals with disease susceptibility, timing prophylactically safe interventions to specific windows during development may prevent or arrest disease progression.

    The paper reports the results obtained during an experimental campaign aimed at transferring aerobic granulation to a demonstrative SBBGR system (i.e., a submerged biofilter that operates in a "fill and draw" mode) for the treatment of municipal wastewater by financial support of the European Commission, within the framework of Life-Environment Programme (PERBIOF Project; www.perbiof-europe.com). The results show that following the generation of granular biomass during the start-up period, the SBBGR was able to remove 80-90% of COD, total suspended solids and ammonia occurring in primary effluent from a municipal wastewater treatment plant even when the minimum hydraulic residence time (i.e., 4 h) was investigated. The process was characterised by a sludge production almost one magnitude order lower than commonly reported for conventional treatment plants. The granular biomass was characterised by a high density (i.e., 150 gTSS/L(biomass)) that allowed a biomass concentration as high as 35 kgTSS/m(3)(bed) to be achieved. Proteobacteria were found as main microbial components of the granular biomass by applying Fluorescence In Situ Hybridization (FISH). No significant changes in microbial composition were observed during reactor operation. PMID:19092218

    A total of 108 patients have filled in questionnaires on falling asleep, sleeping, night awakenings and other characteristics. Their answers have been analysed and it was concluded that night sleep of patients especially in the postoperative period was characterized by prolonged period of falling asleep (over 30 min in 50% of patients), reduced duration, in 77% of patients night awakenings have been recorded. The use of analgin (1000 mg) in combination with dimedrol (10 mg), promedol (20 mg) for tramal (100 mg) for normalization of sleep in the postoperative period was of little efficacy. Therapy of night sleep disturbances will improve the patients' condition and enhance the efficacy of management after surgical interventions. PMID:8010509

    Objective Empirical studies have now established that clinical anxiety and depressive disorders may arise in preschool children as early as age 3.0. As empirical studies validating and characterizing these disorders in preschoolers are relatively recent, less work has been done on the development and testing of age-appropriate treatments. Method A comprehensive literature search revealed several small randomized controlled trials (RCTs) of psychotherapeutic treatments for preschool anxiety and depression. The literature also contains case series of behavioral and psychopharmacologic interventions for specific anxiety disorders. However, to date, no large-scale RCTs of treatment for any anxiety or depressive disorder specifically targeting preschool populations have been published. Results Several age-adapted forms of cognitive behavioral therapy have been developed and preliminarily tested in small RCTs, and appear promising for a variety of forms of preschool anxiety disorders. Notably, these adaptations centrally involve primary caregivers and utilize age-adjusted methodology such as cartoon-based materials and co-constructed drawing or narratives. Modified forms of Parent Child Interaction Therapy (PCIT) have been tested and appear promising for both anxiety and depression. While preventive interventions that target parenting have shown significant promise in anxiety, these methods have not been explored in area of early childhood depression. Studies of the impact of parental treatment on infants suggest that direct treatment of the youngest children may be necessary to affect long-term change. Conclusions Recommendations are made for clinical treatment of these disorders where psychotherapy is the first line of intervention. PMID:23582866

    2009-01-01

    Studies have shown that disturbed sleep produced by chronic alcohol abuse in humans can predict relapse drinking after periods of abstinence. How alcohol produces disturbed sleep remains unknown. In this study we used a novel analysis of sleep to examine the effects of alcohol on sleep patterns in rats. This analysis separates waking into multiple components and defines a period labeled vigilance cycling (VC) in which the rat rapidly cycles through various vigilance states. These VC episodes are separated by long duration wake periods (LDW). We find that 6 weeks of alcohol (6% in a liquid diet) caused fragmentation of extended VC episodes that normally occur in the light period. However, total daily amounts of slow-wave sleep (SWS) and rapid-eye movement sleep (REMS) remained constant. The daily amount of wake, SWS, and REMS remained constant because the alcohol treated rats increased the amount of VC in the dark period, and the sleep nature of VC in the dark period became more intense. In addition, we observed more wake and less REMS early in the light period in alcohol treated rats. All effects completely reversed by day 16 of alcohol withdrawal. Comparison of the effects of chronic alcohol to acute alcohol exposure demonstrated the effects of chronic alcohol are due to adaptation and not the acute presence of alcohol. The effects of chronic alcohol treatment in rats mimic the effects reported in humans (REMS suppression, difficulty falling asleep, and difficulty remaining asleep). PMID:19014977

    This paper summarizes the EPRI report (TR-105202) on the same topic as well as presents changes in current thinking on the suitability (applicability) of chlorine dioxide for fouling control. Chlorine dioxide was tested as a zebra mussel biocide at two steam electric generating stations in Illinois and one in Indiana. The purpose of these studies was to determine the efficacy of chlorine dioxide in killing zebra mussels and to develop site specific treatment programs for the three utilities. The Electric Power Research Institute (EPRI) Zebra Mussel Consortium sponsored the testing of this recent use of chlorine dioxide. The raw water system at Central Illinois Public Service`s Meredosia Station, on the Illinois River, received applications of chlorine dioxide in April, July, and September 1994. The raw water system at Illinois Power Company`s Wood River Station, on the Mississippi River, received applications in July 1993, January, April, May, July, and September 1994. The Gallagher Station, on the Ohio River, was treated in July and October 1994. Chlorine dioxide was generated on-site and injected into the water intake structure. Both cooling and service water systems were treated at the facilities. 6 refs., 13 figs.

    Ascorbic acid, and more recently, the carotenoids lutein and zeaxanthin have been shown to enhance Fe absorption. However, it is not clear whether Fe status improves when foods high in ascorbic acid and carotenoids are consumed with Fe-fortified meals. The present study aimed to investigate whether consuming high v. low ascorbic acid-, lutein- and zeaxanthin-rich fruit (gold kiwifruit v. banana) with Fe-fortified breakfast cereal and milk improved Fe status in women with low Fe stores. Healthy women aged 18-44 years (n 89) with low Fe stores (serum ferritin ≤ 25 μg/l and Hb ≥ 115 g/l) were randomly stratified to receive Fe-fortified breakfast cereal (16 mg Fe as ferrous sulfate), milk and either two gold kiwifruit or one banana (164 mg v. not detectable ascorbic acid; 526 v. 22·90 μg lutein and zeaxanthin, respectively) at breakfast every day for 16 weeks. Biomarkers of Fe status and dietary intake were assessed at baseline and end in the final sample (n 69). Median serum ferritin increased significantly in the kiwifruit group (n 33) compared with the banana group (n 36), with 10·0 (25th, 75th percentiles 3·0, 17·5) v. 1·0 (25th, 75th percentiles - 2·8, 6·5) μg/l (P < 0·001). Median soluble transferrin receptor concentrations decreased significantly in the kiwifruit group compared with the banana group, with - 0·5 (25th, 75th percentiles - 0·7, - 0·1) v. 0·0 (25th, 75th percentiles - 0·3, 0·4) mg/l (P = 0·001). Consumption of an Fe-fortified breakfast cereal with kiwifruit compared with banana improved Fe status. Addition of an ascorbic acid-, lutein- and zeaxanthin-rich fruit to a breakfast cereal fortified with ferrous sulfate is a feasible approach to improve Fe status in women with low Fe stores.

    The response to a time periodic treatment of the immunotherapy in a stochastic model of tumor-immune interaction is numerically investigated. Due to the effect of synchronization among the intrinsic oscillation and the treatment, an enhanced extinction of the tumor cells is observed. It suggests that compared with the static treatment, by controlling the period of the treatment, the time periodic treatment could be an effective way of treatment leading to tumor extinction.

    In this paper, the stochastic resonance phenomenon in a tumor growth model under subthreshold periodic therapy and Lévy noise excitation is investigated. The possible reoccurrence of tumor due to stochastic resonance is discussed. The signal-to-noise ratio (SNR) is calculated numerically to measure the stochastic resonance. It is found that smaller stability index is better for avoiding tumor reappearance. Besides, the effect of the skewness parameter on the tumor regrowth is related to the stability index. Furthermore, increasing the intensity of periodic treatment does not always facilitate tumor therapy. These results are beneficial to the optimization of periodic tumor therapy.

    Recently, nonequilibrium atmospheric-pressure plasmas have been intensively studied for biological applications. However, the each effect of species in plasmas to biological tissue has not been clarified yet because various factors exist in the plasmas. Accordingly, we have studied effects of atomic oxygen dose on cell growth such as budding yeast and mouse NIH3T3 fibroblasts of mammalian cells. Both of cells were suspended with PBS, and treated using oxygen radical source. In order to prevent the radicals from reacting with the ambient air, the treatment region was surrounded by a plastic cover and purged with Ar. The proliferative effect of 15 % was observed at the O3Pj dose of around 1 . 0 ×1017 cm-3 in NIH3T3 cells as well as in yeast cells. Moreover, periodic oxygen treatment enhanced the effect in budding yeast cells. The best interval of periodic oxygen radical treatment was around 2 hours, which is almost the same period as that of their cell cycle. With the optimum interval time, we have investigated the effect of the number of the treatments. As the number of treatments increases, the growth rate of budding yeast cells was gradually enhanced and saturated at thrice treatments.

    A method for easy and fast regeneration of aqueous periodate solutions from dialdehyde cellulose (DAC) production by ozone treatment is presented, along with a direct and reliable simultaneous quantification of iodate and periodate by reversed-phase HPLC. The influence of iodate and ozone concentration, solution pH, and reaction time on the regeneration efficiency was studied, as well as the reaction kinetics. Regeneration of spent periodate solutions by ozone was successfully performed in alkaline medium, which favors the formation of free (.) OH radicals, as supported by the addition of radical scavengers and quantum mechanical calculations. At pH 13 and an ozone concentration of approximately 150 mg L(-1) , periodate was completely regenerated from a 100 mm solution of iodate within 1 h at room temperature. A cyclic process of cellulose oxidation and subsequent regeneration of spent periodate with 90 % efficiency has been developed. So far, commercial applications of DAC have been hampered by difficulties in reusing the costly periodate. This work overcomes this hurdle and presents a highly efficient, clean, and low-cost protocol for the preparation of DAC with integrated periodate recycling, with the possibility of scaling the process up.

    The orientation control of soft matter to create a large area single domain is one of the most exciting research topics in materials science. Recently, this effort has been extended to fabricate two- or three-dimensional structures for electro-optical applications. Here, we create periodic zigzag structures in liquid crystals (LCs) using a combination of surface treatment and thermal annealing. The LC molecules in the nematic (N) phase were initially guided by the alignment layer of rubbed polymers, which were quenched and subsequently annealed in the smectic A (SmA) phase to create periodic zigzag structures that represent modulated layer structures. Direct investigation of the zigzags was performed using microscopy and diffraction techniques, showing the alternately arranged focal conic domains (FCDs) formed. The resulting macroscopic periodic structures will be of interest in further studies of the physical properties of soft matters. PMID:26355381

    Objective To investigate whether proanthocyanidins (PA) is capable of improving dentin collagen’s biological stability through cross-linking within time periods that are clinically relevant. Materials and methods Demineralized dentin collagen slabs were treated with 3.75 wt% PA solution for 10 s, 1 min, 30 min, 60 min, 120 min, 360 min, and 720 min, respectively. The resultant cross-linked collagen samples were subject to digestion with 0.1% collagenase at 37 °C for 2 h, 6 h, 12 h, 24 h, 36 h, and 48 h. The percentage of weight loss after digestion was calculated to evaluate PA-treated collagen’s resistance toward enzymatic degradation. Fourier-Transformed Infrared (FTIR) spectroscopy was used to probe evidences of PA-collagen interactions after various periods of PA treatment. Results The collagenase digestion assay suggests that PA treatment as short as 10 s can enhance collagen’s resistance toward enzymatic challenge. The FTIR spectroscopy further verifies that PA is indeed incorporated into collagen regardless of treatment time, possibly via a mechanism involving the chemical interactions between PA and collagen. Significance This study confirmed that PA can effectively cross-link collagen and improve its biological stability in time periods as short as 10 s. The use of PA as a priming agent is therefore clinically feasible and is a promising approach to improving the durability of current dentin bonding systems. PMID:23434233

  8. Formation of nanoporous structures in metallic materials by pulse-periodic laser treatment

    2015-09-01

    A method of the formation of nanoporous structures in metallic materials by pulse-periodic laser treatment was developed. In this study, the multicomponent aluminum-iron brass was considered and the nanoporous structure across the entire cross section of the material with a thickness of 50 μm was formed. The method was implemented using a CO2 laser processing unit. The pulse-periodic laser treatment of the Cu-Zn-Al-Fe alloy with pulse frequency of 5 Hz has led to the formation of nanosized cavities due to accumulation of internal stresses during cyclic heating and cooling at high speeds. It was determined that the pores of a channel type with average widths of 80-100 nm are formed in the central region of the heat-affected zone during laser action with thermocycling. When implementing the chosen conditions of the pulse-periodic laser processing, the localness in depth and area of the physical processes occurring in the heat-affected zone is ensured, while maintaining the original properties of the material and the absence of significant deformations in the rest of the volume. This patented process is perspective for the production not only catalysts for chemical reactions, but for ultrafiltration and microfiltration membranes as well.

    Transfusion treatment is administered according to clinical and laboratory results, with ongoing patient assessments. Decisions on necessary measures to prevent any adverse and unexpected events and reactions are made on the basis ofhemovigilance and ongoing gathering and analysis of relevant data. Information about transfusion treatment at the Sestre milosrdnice University Hospital Center, Vinogradska site, was retrospectively collected for a period of twelve years (2001-2012). In that period, 14137.25 ± 1693.07 units of all blood products were used, where red blood cells (RBC) accounted for 67.34%, fresh frozen plasma (FFP) for 17.55%, and platelet concentrates (PC) for 14.32%. During the study period, the consumption of RBC was even, of FFP decreased by 45% and of PC increased by 58%. RBC transfusions were received by 10.43% of hospitalized patients, 1.46% of them during surgical procedures. Transfusions of all blood products were received by 14.63% of patients. We found 247 adverse reactions to all blood products. Febrile nonhemolytic and allergic reactions were quite equally represented, 49.5% each. As for other reactions (1%), one transfusion associated circulatory overload and one transfusion related acute lung injury were recorded. There were no fatal post-transfusion reactions.

    Tumor necrosis factor receptor-associated periodic syndrome (TRAPS) is a rare autosomal dominant disease included in the group of autoinflammatory syndromes. It is characterized by recurrent episodes of fever and inflammation in different regions of the body. The main clinical manifestations are myalgia, migratory erythematous rash, periorbital edema, and abdominal pain. The diagnosis is reached using gene analysis and prognosis depends on the appearance of amyloidosis secondary to the recurrent episodes of inflammation. Tumor necrosis factor inhibitors and corticosteroids are the most widely used treatments. In recent years, significant advances have been made in the diagnosis and treatment of TRAPS, thanks to a better understanding of its pathogenesis. Dermatologists must be aware that the skin manifestations of TRAPS are particularly important, as they are often diagnostic. PMID:23891452

    The advanced Resistive Exercise Device (aRED) is a resistive exercise system designed to maintain muscle mass and strength in microgravity by simulating free weight (FW) exercise. aRED utilizes vacuum cylinders and inertial flywheels to replicate the constant mass and inertial components, respectively, of FW exercise in normal gravity. PURPOSE: To compare the effectiveness of aRED and FW resistive exercise training in ambulatory subjects. METHODS: Untrained subjects were assigned to two groups, FW (6 males, 3 females) and aRED (8 males, 3 females), and performed squat (SQ), heel raise (HR), and deadlift (DL) exercises 3 d wk-1 for 16 wks. SQ, HR and DL strength (1RM) were measured using FW hardware pre-, mid- and post-training. Subjects participated in a periodized training protocol with the exercise prescription based on a percentage of 1RM. Thigh and lower leg muscle volume were assessed using Magnetic Resonance Imaging (MRI), and leg (LLM) and total body lean mass (BLM) were measured using Dual Energy X-ray Absorptiometry (DXA) pre- and post-training. RESULTS: SQ 1RM increased in both FW (48.9+/-6.1%) and aRED (31.2+/-3.8%) groups, and there was a greater training response in FW compared with aRED (p=0.01). HR and DL 1RM increased in FW (HR: 12.3+/-2.4%, DL: 23.3+/-4.4%) and aRED (HR: 18.0+/-1.6%, DL: 23.2+'-2.8%), but there were no differences between groups. Thigh muscle volume was greater following training in both groups (FW: 9.8+/-0.9%, aRED: 7.1+/-1.2%) but lower leg muscle volume increased only in the FW group (3.0+/-1.1%). Lean tissue mass increased in both FW (LLM: 3.9+/-1.1%, BLM: 2.5+/-0.7%) and aRED (LLM: 4.8+/-0.7%, BLM: 2.6 0.7%). There were no between group differences in muscle volume or lean mass in response to training. CONCLUSIONS: In general, the increase in muscle strength, muscle volume, and lean tissue mass when training with aRED was not different than when using the same training protocol with FW. The smaller increase in SQ 1RM in the a

    Objective. Thyrotoxic periodic paralysis (TPP) is a potentially life-threatening complication of Graves' disease (GD). The present study compared the long-term efficacy of antithyroid drugs (ATD), radioactive iodine (RAI), and surgery in GD/TPP. Methods. Sixteen patients with GD/TPP were followed over a 14-year period. ATD was generally prescribed upfront for 12–18 months before RAI or surgery was considered. Outcomes such as thyrotoxic or TPP relapses were compared between the three modalities. Results. Eight (50.0%) patients had ATD alone, 4 (25.0%) had RAI, and 4 (25.0%) had surgery as primary treatment. Despite being able to withdraw ATD in all 8 patients for 37.5 (22–247) months, all subsequently developed thyrotoxic relapses and 4 (50.0%) had ≥1 TPP relapses. Of the four patients who had RAI, two (50%) developed thyrotoxic relapse after 12 and 29 months, respectively, and two (50.0%) became hypothyroid. The median required RAI dose to render hypothyroidism was 550 (350–700) MBq. Of the 4 patients who underwent surgery, none developed relapses but all became hypothyroid. Conclusion. To minimize future relapses, more definitive primary treatment such as RAI or surgery is preferred over ATD alone. If RAI is chosen over surgery, a higher dose (>550 MBq) is recommended.

    Background The low prevalence of allergic disease in the rural tropics has been attributed to the protective effects of chronic helminth infections. There is concern that treatment-based control programmes for these parasites may lead to an increase in the prevalence of allergic diseases. Objective We measured the impact of 15–17 years of anthelmintic treatment with ivermectin on the prevalence of allergen skin test reactivity and allergic symptoms in school-age children. Methods The prevalence of allergen skin test reactivity, exercise-induced bronchospasm and allergic symptoms was compared between school-age children living in communities that had received community-based treatments with ivermectin (for onchocerciasis control) for a period of 15–17 years with those living in geographically adjacent communities that had received no ivermectin. Results The prevalence of allergen skin test reactivity was double in children living in treated communities compared with those in untreated communities (16.7% vs. 8.7%, adjusted OR 2.10, 95% CI 1.50–2.94, P<0.0001), and the effect was mediated partly by a reduced prevalence of Trichuris trichiura among treated children. Ivermectin treatments were associated with an increased prevalence of recent eczema symptoms (adjusted OR 2.24, 95% CI 1.05–4.78, P=0.04) but not symptoms of asthma or rhino-conjunctivitis. The effect on eczema symptoms was not associated with reductions in geohelminth infections. Conclusion Long-term periodic treatments with ivermectin were associated with an increased prevalence of allergen skin test reactivity. There was some evidence that treatment was associated with an increased prevalence of recent eczema symptoms but not those of asthma or rhino-conjunctivitis. Cite this as: P. Endara, M. Vaca, M. E.

    Bronchial asthma is a common disease in both the pediatric and adult populations, characterized by wide variations over short periods of time in resistance to airflow in intrapulmonary airways. A primary goal in the use of low- level laser therapy (LLLT) was the safe, effective and rapid palliation of symptoms owing to tracheal or bronchial obstruction. We have investigated the effects of LLLT comparatively with other modality trials in children's asthma. In the study were included 98 patients aged 10-18 years diagnosed with moderate or severe asthma, in attack- free period. The patients were divided into 3 groups. Group 1 received only laser therapy using extra meridian acupuncture points and scanning technique. Group 2 was treated only with inhaled Serevent 2 X 25 micrometers , two times daily, 3 months. Group 3 was tread with Theophylline retard in dosage of 15-mg/kg/12 h, 3 months. At the end of treatment we remarked a noticeable improvement of the clinical, functional and immunological characteristics at 83 percent of patients in group 1, comparatively with only 70 percent (group 2) and 53 percent (group 3). The LLLT had a very good action on bronchial patency , displayed an immunocorrecting action and is recommended in attack-free periods at children.

    This study further evaluates the efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP). A diagnostically heterogeneous clinical sample of 37 patients with a principal anxiety disorder diagnosis was enrolled in a randomized controlled trial (RCT) involving up to 18 sessions of treatment and a 6-month follow-up period. Patients were randomly assigned to receive either immediate treatment with the UP (n=26) or delayed treatment, following a 16-week wait-list control period (WLC; n= 11). The UP resulted in significant improvement on measures of clinical severity, general symptoms of depression and anxiety, levels of negative and positive affect, and a measure of symptom interference in daily functioning across diagnoses. In comparison, participants in the WLC condition exhibited little to no change following the 16-week wait-list period. The effects of UP treatment were maintained over the 6-month follow-up period. Results from this RCT provide additional evidence for the efficacy of the UP in the treatment of anxiety and comorbid depressive disorders, and provide additional support for a transdiagnostic approach to the treatment of emotional disorders.

    The treatment of partial nefrectomies is usually performed under a warm ischemic period. Recently, various treatment modalities have become available to perform a partial nefrectomy without clamping off the blood circulation. We have studied three devices in laboratory setting, investigating the thermal and high speed imaging techniques in tissue models and consequently, applying the instruments in the clinic during open procedures especially looking at efficacy and blood loss. The continuous wave 2.0 micron laser of 70 W (Revolix, LISA laser) is used as a fiber delivered knife cutting through circulated tissue with controlled hemostasis for vessels up to 3 mm diameter. The 2 μm wavelength effectively vaporizes tissue water and coagulates the smaller vessels. The Hydro-Jet (ERBE, Germany) uses high pressure (20-80 bar) to ejects a water jet of 40 um diameter at high velocity (10-30 m/s). The parenchyma is resected while vessels are preserved. Consequently, the exposed vessels can be coagulated in a controlled way with minimal blood loss. The water jet showed to induce cavitation bubbles that resect the soft tissue from the matrix leaving the elastic microvessels intact. Various systems are based on bipolar RF technology. We are using the Habib device (Rita 1500X RF generator) to create a coagulation zone around the tumor. Subsequently, the tumor can be resected along the coagulation zone with minimal bleeding. The treatment modalities investigated, have their own advantages and, stand-alone or in combination, can facilitate laparoscopic partial nephrectomies without an ischemic period.

  17. Linear-scaling explicitly correlated treatment of solids: Periodic local MP2-F12 method

    SciTech Connect

    Usvyat, Denis

    2013-11-21

    Theory and implementation of the periodic local MP2-F12 method in the 3*A fixed-amplitude ansatz is presented. The method is formulated in the direct space, employing local representation for the occupied, virtual, and auxiliary orbitals in the form of Wannier functions (WFs), projected atomic orbitals (PAOs), and atom-centered Gaussian-type orbitals, respectively. Local approximations are introduced, restricting the list of the explicitly correlated pairs, as well as occupied, virtual, and auxiliary spaces in the strong orthogonality projector to the pair-specific domains on the basis of spatial proximity of respective orbitals. The 4-index two-electron integrals appearing in the formalism are approximated via the direct-space density fitting technique. In this procedure, the fitting orbital spaces are also restricted to local fit-domains surrounding the fitted densities. The formulation of the method and its implementation exploits the translational symmetry and the site-group symmetries of the WFs. Test calculations are performed on LiH crystal. The results show that the periodic LMP2-F12 method substantially accelerates basis set convergence of the total correlation energy, and even more so the correlation energy differences. The resulting energies are quite insensitive to the resolution-of-the-identity domain sizes and the quality of the auxiliary basis sets. The convergence with the orbital domain size is somewhat slower, but still acceptable. Moreover, inclusion of slightly more diffuse functions, than those usually used in the periodic calculations, improves the convergence of the LMP2-F12 correlation energy with respect to both the size of the PAO-domains and the quality of the orbital basis set. At the same time, the essentially diffuse atomic orbitals from standard molecular basis sets, commonly utilized in molecular MP2-F12 calculations, but problematic in the periodic context, are not necessary for LMP2-F12 treatment of crystals.

    The prevalence of anaemia during pregnancy and post partum is according to the literature and many years clinical experience high. In the submitted work we investigated the incidence of sideropenic anaemia in women during the first three months after a spontaneous delivery, changes of clinical and laboratory indicators of anaemia during this period and the possible effect exerted by administration of iron and iron plus folic acid resp. Ninety pregnant women in the 35th to 39th week of pregnancy were at random divided into three equally sized groups and the following were assessed: haemogram, indicators of iron reserves, serum concentrations of folic acid, vitamin B12, erythropoetin and soluble transferrin receptor, liver tests, total protein + electrophoresis, acute stage proteins. In the first group (T) the women were given, starting on the 4th day after delivery 1 tablet of Tardyferon per day for two months. To the second group (F) for an equal period 1 tablet of Tardyferon Fol per day was administered. Women in the control group (K) had no medication. In the investigation women with medium and severe pregnancy anaemia were not included nor women taking during pregnancy or previously iron preparations or those treated in the past by blood transfusion. After spontaneous delivery (women who had Caesarean section or forceps delivery were eliminated from the study) the women were subjected to the same examinations as before delivery. These examinations were made on the fourth day after delivery and then after monthly intervals for a period of three months. At the same time the subjective condition of the mothers was evaluated after delivery, focused on the development of symptoms typical for anaemia and the possible effect of administered treatment. The investigation was completed by 60 women. During treatment no allergic or other serious side-reactions to the administered drugs calling for discontinuation of treatment were recorded.

    Data from all 225 women operated on for ectopic pregnancy in 1992-1994 at Sahlgrenska University Hospital were collected and compared with three previous cross-sectional investigations from our hospital (1975-1979, 1981-1982 and 1986-1987) in order to evaluate the extent to which surgical treatment and post-operative complications have changed over a 20 year period. Laparoscopic surgery, which was not possible in the 1970s, was used in almost 85% of the ectopic pregnancies in 1992-1994. Conservative treatment was still the most frequently used technique. The complication rate was 1.2% in 1975-1979 when only laparotomies were carried out. After the introduction of laparoscopic surgery (1986-1987), the complication rate rose significantly (7.3%) and continued to increase even when this procedure was established as routine (14.2% in 1992-1994). Post-operative complications were most frequent after conservative laparoscopic surgery (24.4%) while there were no complications after laparotomies. In spite of increasing complication rates the frequency of patients in pre-shock, as well as the proportion of patients with heavy intra-abdominal bleeding and tubal rupture, decreased over time.

    OBJECTIVES: (1) To evaluate the evidence relating to the effectiveness of methods to prevent and treat obesity, and (2) to provide recommendations for the prevention and treatment of obesity in adults aged 18 to 65 years and for the measurement of the body mass index (BMI) as part of a periodic health examination. OPTIONS: In adults with obesity (BMI greater than 27) management options include weight reduction, prevention of further weight gain or no intervention. OUTCOMES: The long-term (more than 2 years) effectiveness of (a) methods to prevent obesity and (b) methods to treat obesity. EVIDENCE: MEDLINE was searched for articles published from 1966 to April 1998 that related to the prevention and treatment of obesity; additional articles were identified from the bibliographies of review articles and the listings of Current Contents. Selection criteria were used to limit the analysis to prospective studies with at least 2 years' follow-up. BENEFITS, HARM AND COSTS: Health benefits of weight reduction were evaluated in terms of alleviation of symptoms, improved management of obesity-related diseases and a reduction in major clinical outcomes. The health risk of weight-reduction methods were briefly evaluated in terms of increased mortality and morbidity. VALUES: The recommendations of this report reflect the commitment of the Canadian Task Force on Preventive Health Care to provide a structured, evidence-based appraisal of whether a manoeuvre should be part of a periodic health examination. RECOMMENDATIONS: (1) Prevention: There is insufficient evidence to recommend in favour of or against community-based obesity prevention programs; however, because of considerable health risks associated with obesity and the limited long-term effectiveness of weight-reduction methods, the prevention of obesity should be a high priority for health care providers (grade C recommendation). (2) Treatment: (a) For obese adults without obesity-related diseases, there is insufficient

    Small intestinal bacterial overgrowth (SIBO) can partly explain irritable bowel syndrome (IBS), and rifaximin has been observed to improve abdominal symptoms in nonconstipated IBS patients. However, there are few reports on the association of the rifaximin treatment periods with the results of a lactulose breath test (LBT). Therefore, we performed a retrospective review of patient charts to investigate the relation between the rifaximin treatment periods with LBT results in nonconstipated IBS patients. We also evaluated the time to achieve a symptomatic improvement in the IBS patients as compared to the changes in the LBT. We reviewed the charts for patients who showed IBS symptoms with documented positive results for LBT during their initial visit and who had a follow-up LBT after treatment with rifaximin. The LBT values were compared to the subjects' symptom scores. A total of 102 subjects had a follow-up LBT to assess LBT normalization. The subjects were divided into groups according to treatment periods of 4 weeks (n = 36), 8 weeks (n = 43), and 12 weeks (n = 23). The groups with a longer treatment exhibited an increase in the hydrogen gas value at 90 min and its sum during 90 min at the initial LBT. There were significant differences in hydrogen gas value at 90 min and in its sum during 90 min at the initial LBT between the groups treated for 4 and 12 weeks. The most significant treatment response was observed during the first 4 weeks for all treatment groups. Symptomatic improvement occurred earlier than LBT normalization in the treatment period over 4 weeks. The results indicate that different rifaximin treatment periods are needed in accordance with LBT levels to effectively eradicate SIBO. PMID:26028929

    Current treatment recommendations for narcolepsy suggest that modafinil should be used as a first-line treatment ahead of conventional stimulants or sodium oxybate. In this study, performed in a tertiary sleep disorders centre, treatment responses were examined following these recommendations, and the ability of sleep-stage sequencing of sleep-onset rapid eye movement periods in the multiple sleep latency test to predict treatment response. Over a 3.5-year period, 255 patients were retrospectively identified in the authors' database as patients diagnosed with narcolepsy, type 1 (with cataplexy) or type 2 (without) using clinical and polysomnographic criteria. Eligible patients were examined in detail, sleep study data were abstracted and sleep-stage sequencing of sleep-onset rapid eye movement periods were analysed. Response to treatment was graded utilizing an internally developed scale. Seventy-five patients were included (39% males). Forty (53%) were diagnosed with type 1 narcolepsy with a mean follow-up of 2.37 ± 1.35 years. Ninety-seven percent of the patients were initially started on modafinil, and overall 59% reported complete response on the last follow-up. Twenty-nine patients (39%) had the sequence of sleep stage 1 or wake to rapid eye movement in all of their sleep-onset rapid eye movement periods, with most of these diagnosed as narcolepsy type 1 (72%). The presence of this specific sleep-stage sequence in all sleep-onset rapid eye movement periods was associated with worse treatment response (P = 0.0023). Sleep-stage sequence analysis of sleep-onset rapid eye movement periods in the multiple sleep latency test may aid the prediction of treatment response in narcoleptics and provide a useful prognostic tool in clinical practice, above and beyond their classification as narcolepsy type 1 or 2.

    Objective To describe antidepressant (AD) use in the treatment of major depressive disorder during a period of economic crisis. Patients and methods This was a retrospective, observational study using population-based databases. Two periods were considered: 1) 2008–2009, precrisis, and 2) 2012–2013, economic crisis. Certain inclusion/exclusion criteria were taken into account for the study (initiation of AD treatment). Patients were followed up for 12 months. The main measures were use (defined daily doses), epidemiologic measures, strategies used and treatment persistence, referrals, and use of resources. Statistical significance was set at P<0.05. Results In the precrisis period, 3,662 patients were enrolled, and 5,722 were enrolled in the period of economic crisis. Average age was 58.8 years and 65.4% were women. Comparing the two periods, major depressive disorder prevalence was 5.4% vs 8.1%, P<0.001. During the period of economic crisis, AD use rose by 35.2% and drug expenditures decreased by 38.7%. Defined daily dose per patient per day was 10.0 mg vs 13.5 mg, respectively, P<0.001. At 12-month follow-up, the majority of patients (60.8%) discontinued the treatment or continued on the same medication as before, and in 23.3% a change of AD was made. Conclusion Primary health care professionals are highly involved in the management of the illness; in addition, during the period of economic crisis, patients with major depressive disorder showed higher rates of prevalence of the illness, with increased use of AD drugs.

    Kimchi, a traditional fermented food regularly consumed in Korea, contains various types of antimicrobial compounds. Among the tested compounds present in common spices used in Kimchi, quercetin showed the highest selectivity index against influenza A virus (IAV) H1N1. In this study, the effect of pretreatment and periodic treatment with quercetin against IAV in Madin-Darby canine kidney cells was observed. Compared to pretreatment, periodic treatment resulted in significantly higher cell viability but lower relative expression of the IAV PA gene and total apoptosis and cell death. To explain the mechanisms underlying the antiviral effects of quercetin treatment, a comparative proteomic analysis was performed in four samples (mock, quercetin-treated, IAV-infected, and quercetin-treated IAV-infected). Among the 220 proteins, 56 proteins were classified nonhierarchically into three clusters and were differentially modulated by quercetin treatment in IAV-infected cells. Post-translational modifications were identified in 68 proteins. In conclusion, periodic treatment with quercetin is effective in reducing IAV infection, and differentially regulates the expression of key proteins, including heat shock proteins, fibronectin 1, and prohibitin to reduce IAV replication.

    Objective: highlight the socioeconomic and environmental determining factors of long-term observance to antiretroviral treatments in developing countries. Method: The regularity of antiretroviral prescriptions renewal at the central pharmacy of the Yaounde Central Hospital (Cameroon) was measured through analysing the medical and pharmaceutical files of 230 patients over the 21 month start-up period. 99 patients were also interviewed during the last six months. The determining factors were analysed according to various socio-economic criteria, linked with the longitudinal study of treatment observance. Results: The huge price decrease of HIV treatments during the start-up period was conducive to an increase in new treatments by a factor 5.76. In this context of an exploding demand, the paper shows that observance is firstly dependent on quality information about illness and treatment protocols, while longer term adherence is partly dependent on financial capability, and includes the strong influence of living conditions and behaviours. Conclusion: The paper recommends the introduction of free treatment as an objective in national sector policies and the organisation of a long term following-up of patients. In the African context of poverty and actual decentralisation of healthcare, the question of the availability of human resources is profoundly enhanced. PMID:25214897

    1. Our objective was to evaluate a possible pharmacokinetic interaction between zolpidem and fluvoxamine in healthy volunteers. 2. The study consisted of two periods: Period 1 (reference), when each volunteer received a single dose of 5 mg zolpidem; and Period 2 (test), when each volunteer received a single dose of 5 mg zolpidem and 100 mg fluvoxamine. Between the two periods, the subjects were treated for 6 days with a single daily dose of 100 mg fluvoxamine. 3. Pharmacokinetic parameters of zolpidem given in each treatment period were calculated using non-compartmental analysis and the data from two periods were compared to determine statistically significant differences. 4. In the two periods of treatments, the mean peak plasma concentrations (C(max)) were 56.4 ± 25.6 ng/mL (zolpidem alone) and 67.3 ± 25.8 ng/mL (zolpidem after pretreatment with fluvoxamine). The t(max), times taken to reach C(max), were 0.83 ± 0.44 and 1.26 ± 0.74 h, respectively, and the total areas under the curve (AUC(0-∞)) were 200.9 ± 116.8 and 512.0 ± 354.6 ng h/mL, respectively. The half-life of zolpidem was 2.24 ± 0.81 h when given alone and 4.99 ± 2.92 h after pretreatment with fluvoxamine. 5. Fluvoxamine interacts with zolpidem in healthy volunteers and increases its exposure by approximately 150%. The experimental data showed the pharmacokinetic interaction between zolpidem and fluvoxamine, and suggest that the observed interaction might be clinically significant, but its relevance has to be confirmed.

    Background Healthcare cost and reforms are at the forefront of international debates. One of the current discussion themes in oncology is whether and how patients’ life changes due to costs of cancer care. In Norway, the main part of the treatment costs is supported by general taxpayer revenues. Objectives The objective of this study was to clarify whether head and neck cancer patients (n=67) in northern Norway experienced financial health-related quality of life (HRQOL) deterioration due to costs associated with treatment. Design HRQOL was examined by the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 in the beginning and in the end of radiation treatment in patients treated at the University Hospital in Northern Norway. Changes in financial HRQOL were calculated and compared by paired sample T-tests. Multiple regression analyses were used to examine correlations among gender, marital status, age and treatment with or without additional chemotherapy and changes in the HRQOL domain of financial difficulties. Results The majority of score results at both time points were in the lower range (mean 15–25), indicating limited financial difficulties. We observed no statistically significant differences by gender, marital status and age. Increasing financial difficulties during treatment were reported by male patients and those younger than 65, that is, patients who were younger than retirement age. The largest effect was seen in singles. However, differences were not statistically significant. Conclusions During the initial phase of the disease trajectory, no significant increase in financial difficulties was found. This is in line with the aims of the Norwegian public healthcare model. However, long-term longitudinal studies should be performed, especially with regard to the trends we observed in single, male and younger patients. PMID:25623815

    The influence of glucocorticoids on the composition and mineral/organic content of the mandible in tested animals after recovery and healing phase was investigated in this work. The results of FTIR analysis demonstrated that bone tissue composition was changed after glucocorticoid treatment. The increase of calcium, magnesium, phosphorus content and mineral part of bones was statistically significant in recovery phase and in treatment phase that included calcitonin and thymus extract. Some changes also happened in the organic part of the matrix, as indicated by intensity changes for already present IR bands and the appearance of new IR bands in the region 3500-1300 cm-1.

    Cryscor is a periodic post-Hartree-Fock program based on local functions in direct space, i.e., Wannier functions and projected atomic orbitals. It uses atom centered Gaussians as basis functions. The Hartree-Fock reference, as well as symmetry information, is provided by the Crystal program. Cryscor presently features an efficient and parallel implementation of periodic local second order Møller-Plesset perturbation theory (MP2), which allows us to study 1D-, 2D- and 3D-periodic systems beyond 1000 basis functions per unit cell. Apart from the correlation energy also the MP2 density matrix, and from that the Compton profile, are available. Very recently, a new module for calculating excitonic band gaps at the uncorrelated Configuration-Interaction-Singles (CIS) level has been added. Other advancements include new extrapolation techniques for calculating surface adsorption on semi-infinite solids. In this paper the diverse features and recent advances of the present Cryscor version are illustrated by exemplary applications to various systems: the adsorption of an argon monolayer on the MgO (100) surface, the rolling energy of a boron nitride nanoscroll, the relative stability of different aluminosilicates, the inclusion energy of methane in methane-ice-clathrates, and the effect of electron correlation on charge and momentum density of α-quartz. Furthermore, we present some first tentative CIS results for excitonic band gaps of simple 3D-crystals, and their dependence on the diffuseness of the basis set. PMID:22334044

    Neonatal rat pups (7 days old) were intubated with either 50 mg/kg body weight or 100 mg/kg body weight of aqueous root extract of Clitoria ternatea (CTR) for 30 days. These rats were then subjected to open field, two compartment passive avoidance and spatial learning (T-Maze) tests (i) immediately after the treatment and (ii) 30 days after the treatment, along with age matched normal and saline control rats. Results showed no change in open field behaviour, but showed improved retention and spatial learning performance at both time points of behavioural tests, indicating the memory enhancing property of CTR which implicates a permanent change in the brain of CTR treated rats.

    Our experience is based on 147 patients with thoracic echinococcosis (TE) who underwent surgery. Of these, 131 (89.1%) patients had pulmonary TE, 3 (2.1%) had extra-pulmonary TE, and 13 (8.8%) had pulmohepatic TE Ninety-nine (67.3%) patients had uncomplicated TE, and 48 (32.7%) had complicated TE. All patients underwent surgery. In 129 (87.8%) patients, we performed cystectomy with capitonage and in 18 (12.2%) cases we performed a lung resection (lobectomy or segmentectomy). Postoperative complications occurred in 2 (1.4%) patients, and recurrence in 2 (1.4%) patients who previously had complicated TE. On admission, there was no evidence of allergic reactions in patients with complicated TE. The average time of postoperative treatment was 13 days. The results of surgical treatment were excellent. The conclusion reached is that a cystectomy with capitonage is the treatment of choice for pulmonary echinococcosis, while lung resection may be necessary if lung tissue has been destroyed by prolonged compression or infection.

    A general theoretical approach to pulsed Overhauser-type dynamic nuclear polarization (DNP) is presented. Dynamic nuclear polarization is a powerful method to create non-thermal polarization of nuclear spins, thereby enhancing their nuclear magnetic resonance signals. The theory presented can treat pulsed microwave irradiation of electron paramagnetic resonance transitions for periodic pulse sequences of general composition. Dynamic nuclear polarization enhancement is analyzed in detail as a function of the microwave pulse length for rectangular pulses and pulses with finite rise time. Characteristic oscillations of the DNP enhancement are found when the pulse-length is stepwise increased, originating from coherent motion of the electron spins driven by the pulses. Experimental low-field DNP data are in very good agreement with this theoretical approach.

    Cryopyrin-associated periodic syndrome (CAPS) encompasses a spectrum of three phenotypes of increasing severity. The syndrome is due to dominant mutations in NLRP3, which encodes a key component of the innate immunity that regulates the secretion of IL-1β. CAPS manifests as systemic inflammation, which compromises quality of life and leads to serious complications and handicap. Anti-IL-1 drugs have shown remarkable efficacy in treating CAPS symptoms and have significantly changed patients' lives. They have acceptable safety profiles but do have some differences. We review three drugs that are currently marketed for CAPS, give additional information for the practical use of these drugs, and provide some recommendations for management. PMID:26312542

    Strawberries are available throughout the year either from production in the field or from high and low tunnel culture. Diversity of production conditions results in new challenges in controlling diseases before and after harvest. Fungicides have traditionally been used to control these diseases; however, their limitations necessitate a search for new approaches. We found that UV-C irradiation of Botrytis cinerea, a major pathogen of strawberry, can effectively kill this fungus if a dark period follows the treatment. The inclusion of a 4-h dark period resulted in almost complete kill of B. cinerea conidia on agar media at a dose of 12.36 J/m2. The UV-C dose did not cause a reduction in photosynthesis in strawberry leaves or discoloration of sepals, even after exposing plants repeatedly (twice a week) for 7 weeks. Although irradiation of dry conidia of B. cinerea with this dose resulted in some survival, the conidia were not infective and not able to cause decay even when inoculated onto a highly susceptible mature apple fruit. Irradiation of strawberry pollen at 12.36 J/m2 did not affect pollen germination, tube growth and length in vitro, or germination and tube growth in the style of hand-pollinated emasculated strawberry flowers. No negative effect of the UV-C treatment was observed on fruit yield and quality in high tunnel culture. In the fruit and flower petal inoculation tests, the UV-C treatment was highly effective in reducing fruit decay and petal infection. This UV-C treatment with an exposure time of 60 s may be useful in controlling gray mold in tunnel production of strawberries and may also have the potential for use in intensive field and indoor production of other fruits and vegetables providing that a 4-h dark period follows the irradiation.

    Forty-three patients with mild-moderate ischemic stroke were studied in the acute period and were divided into two groups. The experimental group consisted of 32 patients who were given Actovegin; the reference group consisted of 11 patients who were given piracetam. Patients were investigated before treatment and at 10 and 30 days; investigations included examination, points assessments of neurological disorders using the original Gusev-Skvortsova scale, neuropsychological tests using the MMSE scale, rheoencephalography, and electroencephalography. Analysis of changes in clinical features in patients treated with Actovegin during the acute period showed that Actovegin had clear positive effects both on general cerebral and on focal neurological symptoms. By the end of treatment, the extent of recovery of impaired functions, assessed in terms of total ischemic points and cognitive functions, was significantly greater in patients treated with Actovegin than in patients given piracetam. These data lead to the conclusion that Actovegin is effective in the treatment of patients with ischemic stroke. PMID:18802768

    Percutaneous transluminal angioplasty has been successfully used for the treatment of transplant renal artery stenosis (RAS). Cutting-balloon angioplasty (CBA) is being used as a second option in pressure-resistant stenosis. It is thought that CBA is less traumatic and therefore restenosis occurs less frequently than in conventional angioplasty. This case report describes the unusual use of a cutting balloon in transplant RAS as a first option in the early postoperative period. Long-term follow-up data are also presented.

    Abstract Objective: to analyze the meanings of leprosy for people treated during the sulfonic and multidrug therapy periods. Method: qualitative nature study based on the Vigotski's historical-cultural approach, which guided the production and analysis of data. It included eight respondents who have had leprosy and were submitted to sulfonic and multidrug therapy treatments. The participants are also members of the Movement for Reintegration of People Affected by Leprosy. Results: the meanings were organized into three meaning cores: spots on the body: something is out of order; leprosy or hanseniasis? and leprosy from the inclusion in the Movement for Reintegration of People Affected by Leprosy. Conclusion: the meanings of leprosy for people submitted to both regimens point to a complex construction thereof, indicating differences and similarities in both treatments. Health professionals may contribute to the change of the meanings, since these are socially constructed and the changes are continuous. PMID:26444163

    Intraosseous hemangiomas in the jaws are rare lesions and may lead to several complications. The authors present a case of a 12-year-old girl with a radiolucent periapical lesion between tooth 35 and 36 where nocturnal exsanguinating bleeding started to occur from periodontal sulcus during orthodontic treatment. Diagnosis of an intraosseous hemangioma in the mandible was based on positive needle aspiration for blood, computed tomography and arteriography. At first the family chose to only follow-up the lesion but episodes of nocturnal hemorrhage were becoming more frequent and a treatment was requested. Embolization and dental extraction were performed in order to treat the lesion. After a follow-up period of 17 years no more cases of hemorrhage occurred and lesion regressed. PMID:25307825

Dyscirculatory metabolic encephalopathy was revealed to be the main pathology with the etiological mechanism based on dyscirculatorhypoxic and metabolic disorders. Complexity of the revealed symptoms testified to an early organism aging in remote periods after exposure to low dose radiation. Pathogenetic schemes were developed for treatment of dyscirculatory encephalopathy in liquidators, which include drugs improving blood supply, antiaggregants, antioxidants and metabolites of the brains in various combinations. Taking into consideration that early appearance of vascular dyscirculatory disorders observed in liquidators is the sign of early aging of the organism, geroprotectors were added to treatment schemes.

    The changes triggered by sperm-induced activation of oocytes, which are required for normal oocyte development, can be mediated by other agents, thereby inducing the parthenogenesis. In this study, we exposed porcine oocytes to 1 mM Ca-EDTA, a metal-ion chelator, at various intervals during 48 hr of in vitro maturation to determine the optimum period of Ca-EDTA treatment for parthenogenetic activation. When the oocytes were cultured with or without Ca-EDTA from 36 hr (post-12), 24 hr (post-24), 12 hr (post-36) and 0 hr (post-48) after the start of maturation culture, the blastocyst formation rates were significantly higher (P<0.05) in the post-24, post-36 and post-48 groups (3.3%, 4.0% and 2.6%, respectively) than those in the control group without treatment (0%). Furthermore, when the oocytes were cultured with Ca-EDTA for 0 hr (control), 12 hr (pre-12), 24 hr (pre-24), 36 hr (pre-36) and 48 hr (pre-48) from the start of maturation culture, the oocytes formed blastocysts only in the pre-36 and pre-48 groups (0.4% or 0.8%, respectively). Pronuclei (<66.7%) were observed only when the periods of Ca-EDTA treatment were more than 12 hr during maturation culture. In the control group, no pronuclei were detected. Our findings demonstrate that porcine immature oocytes can be parthenogenetically activated by Ca-EDTA treatment for at least 24 hr to 36 hr during maturation culture, leading to pronucleus formation followed by the formation of blastocysts.

    This pilot study aimed to refine a treatment approach for traumatic grief due to violent loss. Our Traumatic Grief Treatment Program, a modification of Shear's complicated grief treatment (Shear et al., 2005), comprises psychoeducation, in vivo exposure, imaginal exposure, discussion of memories about and imaginal conversation with the deceased. Thirteen of 15 Japanese women suffering from posttraumatic stress disorder (PTSD) due to traumatic grief completed 12 to 16 weekly individual sessions based on their therapists' recommendations. Assessment scales included the Inventory of Complicated Grief, the Impact of Event Scale-Revised, and the Center for Epidemiologic Studies Depression Scale. There was significant reduction in symptom severity at treatment end, and symptom levels remained low throughout the 12-month follow-up period. Based on Jacobson's Reliable Change Index, 46% showed change on all 3 measures. These findings suggest that our treatment model may be feasible for treating traumatic grief with PTSD in non-Western settings. PMID:21780192

    Objective To compare the efficacy and safety of continuous terbinafine with intermittent itraconazole in the treatment of toenail onychomycosis. Design Prospective, randomised, double blind, double dummy, multicentre, parallel group study lasting 72 weeks. Setting 35 centres in six European countries. Subjects 496 patients aged 18 to 75 years with a clinical and mycological diagnosis of dermatophyte onychomycosis of the toenail. Interventions Study patients were randomly divided into four parallel groups to receive either terbinafine 250 mg a day for 12 or 16 weeks (groups T12 and T16) or itraconazole 400 mg a day for 1 week in every 4 weeks for 12 or 16 weeks (groups I3 and I4). Main outcome measures Assessment of primary efficacy at week 72 was mycological cure, defined as negative results on microscopy and culture of samples from the target toenail. Results At week 72 the mycological cure rates were 75.7% (81/107) in the T12 group and 80.8% (80/99) in the T16 group compared with 38.3% (41/107) in the I3 group and 49.1 % (53/108) in the I4 group. All comparisons (T12 v I3, T12 v I4, T16 v I3, T16 v I4) showed significantly higher cure rates in the terbinafine groups (all P<0.0001). Also, all secondary clinical outcome measures were significantly in favour of terbinafine at week 72. There were no differences in the number or type of adverse events recorded in the terbinafine or itraconazole groups. Conclusion Continuous terbinafine is significantly more effective than intermittent itraconazole in the treatment of patients with toenail onychomycosis. Key messagesGiven a correct diagnosis, fungal nail disease (onychomycosis) is curableTerbinafine is an allylamine antifungal with a primarily fungicidal mode of actionContinuous terbinafine treatment over 12 or 16 weeks achieves higher rates of clinical and mycological cure than intermittent itraconazole given over the same periodsTerbinafine is safe and well tolerated over 12 or 16 weeks of continuous treatment

    To relieve respiratory problems such as apnea in newborns, caffeine citrate is the drug of choice because of its good tolerance and therapeutic index. However, its impact on the intestinal microbial ecosystem and on bacterial translocation in the neonatal period remains insufficiently investigated. Therefore, the objective of this study was to evaluate the effects of caffeine citrate on the establishment of the intestinal microflora and bacterial translocation in rats from birth to the 30th day of life. Newborn Wistar rats were divided into four groups of 14 animals, each subdivided into a control group receiving a placebo (12mL tap water/kg/day) and another treated with caffeine citrate (12mg/kg/day). The animals were nursed by their mothers and weighed daily. A group of 14 rats was killed at birth and after 10, 20, or 30 days of life. Organs in which translocation was assessed (liver, lungs, spleen, and kidneys) and various fragments of intestine (duodenum, jejunum, ileum, and colon) were surgically removed. The bacteriological analysis performed involved enumeration of the total microflora, staphylococci, enterobacteria, and lactobacilli. From the 10th day, caffeine was shown to significantly decrease the weight of treated animals as compared with controls (P<0.05). However, caffeine treatment did not drastically alter the kinetics of establishment of the intestinal microflora as only enterobacteria were found to be significantly lower in any intestinal segment of the treated group (P<0.05). Moreover, from the 20th day of life, caffeine citrate significantly downregulated bacterial translocation of both Gram-positive and -negative bacteria (P<0.05). This preliminary study on the effects of treatment with caffeine citrate may open opportunities in clinical pediatrics; the treatment will remain partially effective in preventing bacterial translocation in the neonatal period.

    The purpose of this research was to test for association between polymorphisms in the circadian clock-related gene PERIOD2 (PER2) and attrition in patients prone to withdrawal from a behavioral weight-reduction program based on the Mediterranean diet. A total of 454 overweight/obese participants (women=380, men=74), aged 20 to 65 years, who attended outpatient clinics specializing in obesity between January and December 2008, were studied. Anthropometric, biochemical, and dietary-intake variables were analyzed. Effectiveness of the program was assessed, and a questionnaire of barriers to weight loss was considered. Multivariate analysis and logistic regression models were performed. Results indicate that PER2 polymorphisms rs2304672C>G and rs4663302C>T were associated with abdominal obesity (P<0.05). Participants who withdrew from treatment were significantly more obese and had more barriers to lose weight (P<0.05). They also displayed a lower likelihood of planning eating in advance and experiencing stress with dieting than those who completed treatment. Frequency of rs4663307 minor allele was significantly greater in withdrawers than in those who successfully completed treatment (P<0.05). Logistic regression analysis showed that rs2304672 C>G minor allele carriers had a greater probability of dropping out, displaying extreme snacking, experiencing stress with dieting, eating when bored, and skipping breakfast than noncarriers. PER2 is implicated in attrition in weight-loss treatment and may modulate eating-behavior-related phenotypes. These findings could represent a step toward personalized health care and nutrition based on a combination of genotyping and psycho-behavioral characterization. PMID:20497782

    The rapid growth of observed exoplanets has revealed the existence of several distinct planetary populations in the mass-period diagram. Two of the most surprising are (1) the concentration of gas giants around 1 AU and (2) the accumulation of a large number of low-mass planets with tight orbits, also known as super-Earths and hot Neptunes. We have recently shown that protoplanetary disks have multiple planet traps that are characterized by orbital radii in the disks and halt rapid type I planetary migration. By coupling planet traps with the standard core accretion scenario, we showed that one can account for the positions of planets in the mass-period diagram. In this paper, we demonstrate quantitatively that most gas giants formed at planet traps tend to end up around 1 AU, with most of these being contributed by dead zones and ice lines. We also show that a large fraction of super-Earths and hot Neptunes are formed as 'failed' cores of gas giants—this population being constituted by comparable contributions from dead zone and heat transition traps. Our results are based on the evolution of forming planets in an ensemble of disks where we vary only the lifetimes of disks and their mass accretion rates onto the host star. We show that a statistical treatment of the evolution of a large population of planetary cores caught in planet traps accounts for the existence of three distinct exoplanetary populations—the hot Jupiters, the more massive planets around r = 1 AU, and the short-period super-Earths and hot Neptunes. There are very few populations that feed into the large orbital radii characteristic of the imaged Jovian planet, which agrees with recent surveys. Finally, we find that low-mass planets in tight orbits become the dominant planetary population for low-mass stars (M {sub *} ≤ 0.7 M {sub ☉}).

    This is the second part of a retrospective study of 400 root-fractured permanent incisors. In this article, the effect of various treatment procedures is analyzed. Treatment delay, i.e. treatment later than 24 h after injury, did not change the root fracture healing pattern, healing with hard tissue between fragments (HH1), interposition of bone and/or periodontal ligament (PDL) or pulp necrosis (NEC). When initial displacement did not exceed 1 mm, optimal repositioning appeared to significantly enhance both the likelihood of pulpal healing and hard tissue repair (HH1). Significant differences in healing were found among the different splinting techniques. The lowest frequency of healing was found with cap splints and the highest with fiberglass or Kevlar splints. The latter splinting procedure showed almost the same healing result as non-splinting. Comparison between non-splinting and splinting for non-displaced teeth was found to reveal no benefit from splinting. With respect to root fractures with displacement, too few cases were available for analysis. No beneficial effect of splinting periods greater than 4 weeks could be demonstrated. The administration of antibiotics had the paradoxical effect of promoting both HH1 and NEC. No explanation could be found. It was concluded that, optimal repositioning seems to favor healing. Furthermore, the chosen splinting method appears to be related to healing of root fractures, with a preference to pulp healing and healing fusion of fragments to a certain flexibility of the splint and possibly also non-traumatogenic splint application. Splinting for more than 4 weeks was not found to influence the healing pattern. A certain treatment delay (a few days) appears not to result in inferior healing. The role of antibiotics upon fracture healing is questionable. PMID:15245519

    Background The Sphingosine-1-phosphate (S1P) signaling pathway is known to influence pathophysiological processes within the brain and the synthetic S1P analog FTY720 has been shown to provide neuroprotection in experimental models of acute stroke. However, the effects of a manipulation of S1P signaling at later time points after experimental stroke have not yet been investigated. We examined whether a relatively late initiation of a FTY720 treatment has a positive effect on long-term neurological outcome with a focus on reactive astrogliosis, synapses and neurotrophic factors. Methods We induced photothrombotic stroke (PT) in adult C57BL/6J mice and allowed them to recover for three days. Starting on post-stroke day 3, mice were treated with FTY720 (1 mg/kg b.i.d.) for 5 days. Behavioral outcome was observed until day 31 after photothrombosis and periinfarct cortical tissue was analyzed using tandem mass-spectrometry, TaqMan®analysis and immunofluorescence. Results FTY720 treatment results in a significantly better functional outcome persisting up to day 31 after PT. This is accompanied by a significant decrease in reactive astrogliosis and larger post-synaptic densities as well as changes in the expression of vascular endothelial growth factor α (VEGF α). Within the periinfarct cortex, S1P is significantly increased compared to healthy brain tissue. Conclusion Besides its known neuroprotective effects in the acute phase of experimental stroke, the initiation of FTY720 treatment in the convalescence period has a positive impact on long-term functional outcome, probably mediated through reduced astrogliosis, a modulation in synaptic morphology and an increased expression of neurotrophic factors.

    Objective Program implementers have argued that the increasing availability of anti-retroviral therapy (ART) will reduce the stigma of HIV. We analyzed data from Uganda to assess how HIV-related stigma has changed during a period of ART expansion. Design Serial cross-sectional surveys. Methods We analyzed data from the Uganda AIDS Rural Treatment Outcomes (UARTO) study during 2007-2012 to estimate trends in internalized stigma among people living with HIV (PLHIV) at the time of treatment initiation. We analyzed data from the Uganda Demographic and Health Surveys (DHS) from 2006 and 2011 to estimate trends in stigmatizing attitudes and anticipated stigma in the general population. We fitted regression models adjusted for socio-demographic characteristics, with year of data collection as the primary explanatory variable. Results We estimated an upward trend in internalized stigma among PLHIV presenting for treatment initiation (adjusted b=0.18; 95% CI, 0.06 to 0.30). In the general population, the odds of reporting anticipated stigma were greater in 2011 compared to 2006 (adjusted OR=1.80; 95% CI, 1.51 to 2.13), despite an apparent decline in stigmatizing attitudes (adjusted OR=0.62; 95% CI, 0.52 to 0.74). Conclusions Internalized stigma has increased over time among PLHIV in the setting of worsening anticipated stigma in the general population. Further study is needed to better understand the reasons for increasing HIV-related stigma in Uganda and its impact on HIV prevention efforts. PMID:25268886

  14. Methodological challenges in monitoring new treatments for rare diseases: lessons from the cryopyrin-associated periodic syndrome registry

    2013-01-01

    Background The Cryopyrin-Associated Periodic Syndromes (CAPS) are a group of rare hereditary autoinflammatory diseases and encompass Familial Cold Autoinflammatory Syndrome (FCAS), Muckle-Wells Syndrome (MWS), and Neonatal Onset Multisystem Inflammatory Disease (NOMID). Canakinumab is a monoclonal antibody directed against IL-1 beta and approved for CAPS patients but requires post-approval monitoring due to low and short exposures during the licensing process. Creative approaches to observational methodology are needed, harnessing novel registry strategies to ensure Health Care Provider reporting and patient monitoring. Methods A web-based registry was set up to collect information on long-term safety and effectiveness of canakinumab for CAPS. Results Starting in November 2009, this registry enrolled 241 patients in 43 centers and 13 countries by December 31, 2012. One-third of the enrolled population was aged < 18; the overall population is evenly divided by gender. Enrolment is ongoing for children. Conclusions Innovative therapies in orphan diseases require post-approval structures to enable in depth understanding of safety and natural history of disease. The rarity and distribution of such diseases and unpredictability of treatment require innovative methods for enrolment and follow-up. Broad international practice-based recruitment and web-based data collection are practical. PMID:24016338

    Onions of "Dorata di Parma" variety were exposed to 10 Krads of Co60 gamma irradiation in 5, 10, 20, 40, and 80 minutes in December, 1975 and then stored in the cold storage (10 +/- 1 degree C; R.H. 65-70%) and at the room temperature (15-20 degrees C; R.H. 40-70%) for 3 months, to study the influence of dose-rate and post-harvest period of treatment. Average number of buds sprouted in each onion bulb under cold storage condition ranged from 2-3, while this number was found to increase to 3-4 under ambient storage conditions. Although no effect of either irradiation or dose rate was observed when onions were irradiated after the break of their dormancy, however, a significant slowing down effect of irradiation could be observed as far as the rate of growth of sprouts was concerned. Weight loss was also reduced significantly in the irradiated onions as compared with controls. PMID:1037423

    The microbiome and immune system of the digestive tract are highly important in both health and disease. Exclusive enteral nutrition (EEN) is a common anti-inflammatory treatment in children with Crohn's disease in the European countries, and the mechanism is most likely linked to changes in the intestinal microbiome. In the present study, EEN was given in two treatment periods several months apart to a patient with very severe, disabling juvenile idiopathic arthritis (JIA), with a remarkable clinical response as the result. The aim of the present study was to study how the EEN treatment influenced the microbiome and metabolome of this patient. Fecal samples from before, during, and between treatments with EEN were studied. The microbiome was analyzed by sequencing of 16S rRNA amplicons using Illumina MiSeq, and the metabolome was analyzed using nuclear magnetic resonance. The microbiome changed markedly from treatment with EEN, with a strong reduction of the Bacteroidetes phylum. Metabolic profiles showed clear differences before, during, and between treatment with EEN, where butyrate, propionate, and acetate followed a cyclic pattern with the lowest levels at the end of each treatment period. This patient with JIA showed remarkable clinical improvement after EEN treatment, and we found corresponding changes in both the fecal microbiome and the metabolome. Further studies are needed to explore the pathophysiological role of the intestinal canal in children with JIA. PMID:27021336

    This paper describes an individual who was diagnosed with obsessive-compulsive disorder (OCD) and body dysmorphic disorder (BDD) at age 17 when education was discontinued. By age 19, he was housebound without social contacts except for parents. Adequate trials of three selective serotonin reuptake inhibitors, two with atypical neuroleptics, were ineffective. Major exacerbations following ear infections involving Group A beta-hemolytic streptococcus at ages 19 and 20 led to intravenous immune globulin therapy, which was also ineffective. At age 22, another severe exacerbation followed antibiotic treatment for H. pylori. This led to a hypothesis that postulates deficient signal transduction by the N-methyl-D-aspartate receptor (NMDAR). Treatment with glycine, an NMDAR coagonist, over 5 years led to robust reduction of OCD/BDD signs and symptoms except for partial relapses during treatment cessation. Education and social life were resumed and evidence suggests improved cognition. Our findings motivate further study of glycine treatment of OCD and BDD. PMID:20182547

    Purpose Corneal graft rejection is the most common reason for the failure of an allograft corneal transplant. We undertook this study to identify and compare risk factors and treatment outcomes for early and late corneal graft rejections after optical penetrating keratoplasty. Methods A retrospective case file analysis of 880 primary penetrating keratoplasties was performed at a tertiary ophthalmic care centre. Patients were divided into early rejectors (rejection episode within 6 months postoperatively) and late rejectors (rejection episode after 6 months postoperatively). Main parameters evaluated were demographics, preoperative diagnosis and clinical signs, donor tissue details, surgical technique, details of rejection episode, treatment, and outcome information. Results A total of 156 patients with rejection episodes were identified. Of these, 42 (26.9%) patients experienced early rejection episodes and 114 (73.1%) patients experienced late rejection episodes. Preoperative donor and recipient characteristics, surgical technique, and clinical presentation of graft rejection were found to be similar between both groups after a Bonferroni correction was applied (P>0.005). Treatment outcomes of graft rejections were not significantly different (P=0.46) between early and late rejectors, with 83% of patients responding to rejection treatment (80% early rejectors; 85% late rejectors). Conclusion Patients with early and late graft rejection have similar characteristics and both groups respond to treatment equally. PMID:22344190

    Neurodegenerative disorders such as Alzheimer's disease (AD) are characterized by the loss of neurotrophic factors, and experimental therapeutical approaches to AD have investigated the efficacy of replacing or augmenting neurotrophic factor activity. Cerebrolysin, a peptide mixture with neurotrophic-like effects, has been shown to improve cognition in patients with AD and to reduce synaptic and behavioral deficits in transgenic (tg) mice overexpressing the amyloid precursor protein (APP). However, it is unclear how long-lasting the beneficial effects of Cerebrolysin are and whether or not behavioral and neuropathological alterations will reappear following treatment interruption. The objective of the present study was to investigate the consequences of interrupting Cerebrolysin treatment (washout effect) 3 and 6 months after the completion of a 3-month treatment period in APP tg mice. We demonstrate that, in APP tg mice, Cerebrolysin-induced amelioration of memory deficits in the water maze and reduction of neurodegenerative pathology persist for 3 months after treatment interruption; however, these effects dissipate 6 months following treatment termination. Immunohistochemical analysis demonstrated that the decrease in neocortical and hippocampal amyloid plaque load observed in Cerebrolysin-treated APP tg mice immediately after treatment was no longer apparent at 3 months after treatment interruption, indicating that the beneficial effects of Cerebrolysin at this time point were independent of its effect on amyloid-β deposition. In conclusion, the results demonstrate that the effects of Cerebrolysin persist for a significant period of time following treatment termination and suggest that this prolonged effect may involve the neurotrophic factor-like activity of Cerebrolysin.

    2015-10-01

    The presence of anovulatory haemorrhagic follicles during the oestrous cycle of mares causes financial impacts, slowing conception and increasing the number of services per pregnancy. Non-steroidal anti-inflammatory drugs (NSAIDs) such as meloxicam and phenylbutazone are used in the treatment of several disorders in mares, and these drugs can impair the formation of prostaglandins (PGs) and consequently interfere with reproductive activity. This study aimed to evaluate the effects of treatment with NSAIDs on the development of pre-ovulatory follicles in mares. In total, 11 mares were studied over three consecutive oestrous cycles, and gynaecological and ultrasound examinations were performed every 12 h. When 32-mm-diameter follicles were detected, 1 mg of deslorelin was administered to induce ovulation. The first cycle was used as a control, and the mares received only a dose of deslorelin. In the subsequent cycles, in addition to receiving the same dose of deslorelin, each mare was treated with NSAIDs. In the second cycle, 4.4 mg/kg of phenylbutazone was administered, and in the third cycle, 0.6 mg/kg of meloxicam was administered once a day until ovulation or the beginning of follicular haemorrhage. All of the mares ovulated between 36 and 48 h after the induction in the control cycle. In the meloxicam cycle, 10 mares (92%) did not ovulate, while in the phenylbutazone cycle, nine mares (83%) did not ovulate. In both treatments, intrafollicular hyperechoic spots indicative of haemorrhagic follicles were observed on ultrasound. Thus, our results suggested that treatment with meloxicam and phenylbutazone at therapeutic doses induced intrafollicular haemorrhage and luteinization of anovulatory follicles. PMID:26280558

    Purpose: To evaluate the demographics and management outcomes of strabismus surgery in patients with third cranial nerve palsy. Methods: This retrospective study includes subjects with third cranial nerve palsy. We evaluated age, sex, laterality, severity of involvement, etiology, frequency of clinical findings, and types and results of treatments. Results: 52 patients including 29 male and 23 female subjects with mean age of 21.1±15.5 years were studied between January 1999 and January 2009. Etiologies of third nerve palsy included congenital in 16 (30.8%), trauma in 26 (50%) and other causes in 10 (19.2%) patients. In 24 patients (46.2%), the palsy was complete. The most common type of strabismus was exotropia associated with hypotropia (40%). Medical treatment was used in 25 (48%) and surgical treatment in 46 (88.4%) subjects. One time strabismus surgery was performed in 30 (65.2%), 2 times in 11 (24%) and 3 times in 5 (10.8%) subjects. The most common operation was large horizontal recession and resection in 78.2% of cases. Mean horizontal deviation in primary position was 66±29 prism diopters (PD) before surgery decreasing to 21±19, 13±12 and 6±8 PD after first, second and third surgery, respectively. Corresponding figures for mean vertical deviation were 13±15, 7±12, 4±6 and 1±2 PD, respectively. Abnormal head posture was 10-30° in 11 (21.1%) cases before treatment which completely resolved after surgery. Conclusion: Surgical management of strabismus in patients with third nerve palsy is difficult and challenging, however the majority of patients achieve ideal results with appropriate and stepwise surgical plans.

    Background: Cannabis continues to be the most commonly used illicit psychoactive substance globally. The National Survey in India conducted in the year 2004 also reported it to be the most commonly used illicit substance in the country. Furthermore, it was reported to be the second most commonly used psychoactive substance by the treatment seekers at de-addiction centers in the country. Objectives: To assess time trends of cannabis use among treatment-seeking individuals at government de-addiction centers across India over a period of 7 years. Materials and Methods: The study utilized data collected through Drug Abuse Monitoring System across India. The data of treatment seekers from de-addiction centers established under the Drug De-addiction Program, Ministry of Health and Family Welfare, Government of India and supported by the Ministry of Social Justice and Empowerment, Government of India (122 in number) across the country were analyzed. Results: A total of 107,469 individuals sought treatment from government de-addiction centers over the 7 years (2007–2013) period. With the exception of an aberration for the year 2012, there has been a steady decline in the proportion of treatment seekers who are not current cannabis users. A significantly greater proportion (Chi-square: 586.30, df: 1, P < 0.001) of individuals with current cannabis use alone or along with tobacco (20.4%) tend to have a co-morbid psychiatric disorder as compared to treatment seekers with current use of substances other than cannabis (6.1%). Conclusions: It is important to focus on cannabis in clinical service delivery and research in the country.

    Follicular mucinosis (FM) and folliculotropic mycosis fungoides (MF) are rare in children, and data regarding long-term outcomes are limited. We sought to describe clinical and histopathologic findings of children with FM with and without MF, as well as treatments administered and clinical outcomes. We conducted a retrospective chart review of patients younger than 22 years (at time of diagnosis) with a biopsy demonstrating FM who were seen in the Dermatology Department at the Mayo Clinic from September 1, 1999, to September 1, 2010. Eleven patients (six male, five female) ages 11 to 19 years at the time of diagnosis met the inclusion criteria. Follow-up data were available for 10 patients, with a mean duration of 4.9 years. The head, neck, and extremities were the most common sites of involvement, and lesions were follicular-based papules (18%), scaly alopecic patches and plaques (45%), or a combination of the two (36%). Overall, three patients were confirmed to have MF. T-cell receptor gene rearrangement demonstrated clonality in two cases and was equivocal in one case. Treatments included topical corticosteroids, topical retinoids, oral minocycline, and, in patients with MF, ultraviolet light and topical bexarotene. Lesions resolved completely in seven patients, partially in one, and not at all in two (no follow-up data on one patient). Of the three patients with MF, two had complete resolution, and one has intermittent flares. To our knowledge, no patients developed other lymphoproliferative disorders. FM in children is rare. A histopathologic diagnosis of FM does not equate to folliculotropic MF in all cases. Most patients responded to treatment with topical steroids, topical retinoids, or phototherapy. In our series of patients, the disease ran a benign course. PMID:23278316

    The ab initio calculation of charged defect properties in solids is not straightforward because of the delicate interplay between the long-range Coulomb interaction and the periodic boundary conditions. We derive the Projector Augmented-Wave (PAW) energy and hamiltonian with a special care on the potentials from Coulomb interaction. By explicitly treating the background compensation charge, we find a new term in the total energy of charged cells and in the potential. We show that this background term is needed to accurately reproduce all-electron calculations of the formation energy of a charged defect. In particular, the previous PAW expressions were spuriously sensitive to the pseudization conditions and this artifact is removed by the background term. This PAW derivation also provides insights into the norm-conserving pseudopotential framework. We propose then an alternative definition for the total energy of charged cells and for the potential within this framework.

    Circadian rhythms in cardiac function are apparent in e.g., blood pressure, heart rate, and acute adverse cardiac events. A circadian clock in heart tissue has been identified, but entrainment pathways of this clock are still unclear. We cultured tissues of mice carrying bioluminescence reporters of the core clock genes, period 1 or 2 (per1luc or PER2LUC) and compared in vitro responses of atrium to treatment with medium and a synthetic glucocorticoid (dexamethasone [DEX]) to that of the suprachiasmatic nucleus (SCN) and liver. We observed that PER2LUC, but not per1luc is rhythmic in atrial tissue, while both per1luc and PER2LUC exhibit rhythmicity in other cultured tissues. In contrast to the SCN and liver, both per1luc and PER2LUC bioluminescence amplitudes were increased in response to DEX treatment, and the PER2LUC amplitude response was dependent on the time of treatment. Large phase-shift responses to both medium and DEX treatments were observed in the atrium, and phase responses to medium treatment were not attributed to serum content but the treatment procedure itself. The phase-response curves of atrium to both DEX and medium treatments were found to be different to the liver. Moreover, the time of day of the culturing procedure itself influenced the phase of the circadian clock in each of the cultured tissues, but the magnitude of this response was uniquely large in atrial tissue. The current data describe novel entrainment signals for the atrial circadian clock and specifically highlight entrainment by mechanical treatment, an intriguing observation considering the mechanical nature of cardiac tissue.

    The fundamental issue of the region of period formaton in a degenerate star is examined, with special attention given to the treatment of the Brunt-Vaisala frequency. It is shown that, in order to obtain reliable numerical results in degenerate stellar models, the Brunt-Vaisala frequency must be appropriately transformed, because it is defined in terms of a difference between two numbers which become nearly equal in highly degenerate matter, causing serious numerical problems and systematic errors. An alternative expression is derived, which is valid for multicomponent nonideal partially degenerate and partially ionized plasmas such as those encountered in white dwarf envelopes. This expression is used to compute the period structure of the same white dwarf considered by Pesnell (1987). It is shown that the implicit numerical differencing used in the Lagrangian pulsation code of Pesnell leads to very serious difficulties when used with models of degenerate stars.

    Background: Platelet-rich plasma (PRP) is defined as an autologous concentration of plasma with a greater count of platelets than that of whole blood. Its action depends on the released growth factors from platelets. It has been investigated and used in numerous fields of medicine. Recently, PRP has received growing attention as a potential therapeutic tool for hair loss. Aims: To evaluate the efficacy and safety of PRP injections in the scalp of patients with androgenetic alopecia. Settings and Design: Prospective cohort study. Materials and Methods: 20 patients, 18 males and 2 females, with androgenetic alopecia were enrolled in the study. PRP was prepared using a single spin method (Regenlab SA). Upon activation, it was injected in the androgen-related areas of scalp. Three treatment sessions were performed with an interval of 21 days and a booster session at 6 months following the onset of therapy. Statistical Analysis: Statistical analysis of the data was performed using the Statistical Package for the Social Sciences (SPSS), version 19.0 (IBM, NY, USA). Results: Hair loss reduced and at 3 months it reached normal levels. Hair density reached a peak at 3 months (170.70 ± 37.81, P < 0.001). At 6 months and at 1 year, it was significantly increased, 156.25 ± 37.75 (P < 0.001) and 153.70 ± 39.92 (P < 0.001) respectively, comparing to baseline. Patients were satisfied with a mean result rating of 7.1 on a scale of 1-10. No remarkable adverse effects were noted. Conclusions: Our data suggest that PRP injections may have a positive therapeutic effect on male and female pattern hair loss without remarkable major side effects. Further studies are needed to confirm its efficacy. PMID:25722600

    Background Current treatments for schizophrenia are often only partially effective. Aims Assess the possible benefit of using adjunctive Naikan therapy, a cognitive approach based on self-reflection that originated in Japan for the treatment of schizophrenia. Methods After resolution of acute psychotic symptoms, 235 psychiatric inpatients with schizophrenia who had a middle school education or higher were randomly assigned to a control group (n=112) that received routine medication and inpatient rehabilitative treatment or an intervention group (n=123) that also received adjunctive Naikan therapy for 2 hours daily, 5 days a week for 4 weeks. The patients were then discharged and followed up for 12 months. The Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance scale (PSP), and Insight and Attitude Questionnaire (ITAQ) were used to assess patients at enrollment, after the 1-month intervention, and after the 12-month follow-up. Evaluators were blind to the group assignment of patients. Results Only 13 (10.6%) of the intervention group participants relapsed over the 12-month follow-up, but 23 (20.5%) control group participants relapsed (X2=4.50, p=0.034). Using a modified intention-to-treat analysis and a repeated measure analysis of variance, the PANSS, PSP, and ITAQ total scores all showed significantly greater improvement over the 12-month follow-up in the Naikan group than in the control group. The drop in mean chlorpromazine-equivalent dosage from enrollment to the end of follow-up was significantly different in the intervention group but not in the control group, though the change in dosage over time between groups was not statistically significant. Conclusions This study provides robust support for the effectiveness of Naikan therapy as an adjunctive treatment during the recovery period of schizophrenia. Compared to treatment as usually, adjunctive Naikan therapy can sustain the improvement in psychotic symptoms achieved during acute

    2013-01-01

    The primary aim of this study was to determine whether different durations of contingency management (CM) in conjunction with psychosocial treatment produced different rates of abstinence among methamphetamine dependent individuals. Participants were randomized to one of four 16-week treatment conditions: standard psychosocial treatment or psychosocial treatment plus one of three durations of CM (one-month, two-month, or four-month). A total of 118 participants were randomized to the four treatment conditions. There were significant differences across treatment conditions for number of consecutive days of methamphetamine abstinence (p < 0.05). These differences were in the hypothesized direction, as participants were more likely to remain abstinent through the 16-week trial as CM duration increased. A significant effect of treatment condition (p < 0.05) and time (p < 0.05) on abstinence over time was also found. Longer durations of CM were more effective for maintaining methamphetamine abstinence. PMID:23708468

    The aim of the study was to compare the effect of two acute puerperal metritis (APM) treatment protocols on uterine condition during the late puerperal period (5th to 7th week). Late gestation healthy cows (n = 21) were divided randomly in three equal groups. Parturitions were induced. Treatments of APM were started on the third day postpartum (PP). Group A was treated with an oxytocin analogue carbetocin for three days and intrauterine administration of cephapirin between days 15 and 17. Group B was given intramuscular injection of ceftiofur for five days followed by two injections of prostaglandin F2α, at an interval of 12 h, on the eighth day PP. Group C served as the control group with no treatment. Body temperature was recorded daily for 14 days PP. Uterine biopsies for bacteriology, and uterobrush samples for cytology, were taken once a week from the 5th to 7th week postpartum. No differences were found in body temperature on day 14 PP, presence of bacteriological infections and disappearance of uterine inflammatory signs diagnosed by cytological examination between experimental groups.

    The effect of the non-selective treatment of dairy cows with antibiotics (Chronicin foam--Galena, and Masticort PS--Poland) and the effect of teat disinfection (Jodonal A--Lachema) at the last milking in lactation was studied as exerted on the reduction in the occurrence of infection processes in mammary gland after calving. The trials were performed with 180 cows in three groups of 60 animals. At the last milking the mammary secretion of each cow was sampled for bacteriological examination. Two cow groups were treated at the same time. The occurrence of infection processes in the mammary gland in the period after calving can be characterized as follows: a) in the period after calving the control group had an increased proportion of cows with an infection process in their udders (from 58.3% at the end of lactation to 68.3% in the period of 14 days following calving); b) in the group treated with Chronicin foam the infection was reduced by 3/5, i. e. from 71.7% of cows infected at the start of drying off to 28.3% with infection process after calving; c) in the group treated with Masticort PS the infection after calving was reduced by 3/4 as compared with the infection at the onset of drying off, i. e. from 80% to 20%. In the control group 20% of the cows recovered spontaneously. The preparation Chronicin foam showed 79.1% therapeutic effectiveness. Therapy with Masticort PS was successful in 81.3% of the animals.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:6433531

    AIM:To investigate the changes of gastric acid production and its mechanism in shock period of severe burn in rats.METHODS:A rat model with 30% TBSA full thickness burn injury was employed and the gastric acid production,together with gastric mucosal blood flow (GMBF) and energy charge (EC) were measured serially within 48h postburn.RESULTS:The gastric acid production in the acute shock period was markedly inhibited after severe burn injury.At the 3rd h postburn,the gastric juice volume, total acidity and acid output were already significantly decreased (P < 0.01 =, and reached the lowest point, 0.63mL/L ± 0.20mL/L, 10.81mmol/L ± 2.58mmol/L and 2.23mmol/h ± 0.73mmol/h respectively, at the 12th h postburn. Although restored to some degree 24h after thermal injury, the variables above were still statistically lower, compared with those of control animals at the 48th h postburn. The GMBF and EC were also significantly reduced after severe burns, consistent with the trend of gastric acid production changes.CONCLUSION:Gastric acid production, as well as GMBF and EC was predominantly decreased in the early postburn stage, suggesting that gastric mucosal ischemia and hypoxia with resultant disturbance in energy metabolism, but not gastric acid proper, might be the decisive factor in the pathogenesis of AGML after thermal injury, and that the preventive use of anti-acid drugs during burn shock period was unreasonable in some respects. Therefore, taking effective measures to improve gastric mucosal blood perfusion as early as possible postburn might be more preferable for the AGML prevention and treatment. PMID:11819529

    2013-01-01

    The keratocystic odontogenic tumor (KCOT) is a relatively common oral and maxillofacial lesion with specific characteristics such us rapid growth, extension into the surrounding tissues and high rates of recurrence. Various treatment modalities have been reported. Due to the very thin and friable lining characteristic of the tumor, enucleation can be difficult undertaken and for this reason it is associated with the highest recurrence rates. A 22-year-old male referred to our clinic due to a slight expansion in the right mandible from 2 years ago. He has a history of occurrence of KCOT in this region that was treated surgically by enucleation and curettage 5 years ago. Cone beam computed tomography showed a multilocular radiolucent lesion that extended from the angle of the mandible to the symphysis. Incisional biopsy showed a KCOT recurrence that surgically treated with resection of the right mandible by continuity preservation. Selection of the best treatment modality and also a periodical lifelong follow-up is very important to reduce the rate of recurrence and morbidity of the patient. PMID:24049625

    Purpose This study assessed the efficacy of methylphenidate versus placebo for cancer-related fatigue reduction. Other objectives were to analyze cytokine levels and to determine the effects of methylphenidate on other symptoms, cognitive function, work yield, and patients’ perceptions, and preferences. Methods Patients were randomly assigned (1:1) to receive methylphenidate-placebo or placebo-methylphenidate for 4 weeks. Patients crossed over after 2 weeks. Wilcoxon signed-rank tests and McNemar tests were used to assess continuous and categorical variables. The primary efficacy end point was change in the level of worst fatigue on the Brief Fatigue Inventory at the end of each 2-week period. Results The mean baseline Brief Fatigue Inventory was moderate (5.7). Methylphenidate treatment did not affect patients’ worst level of fatigue or other symptoms. Results from the Wechsler Adult Intelligence Scale Digit Symbol Test and the Hopkins Verbal Learning Test with Brief Fatigue Inventory interference questions and Brief Fatigue Inventory activity questions showed significant improvement in the methylphenidate-treated patients’ verbal learning, memory, visual perception, analysis, and scanning speed. Patients treated with methylphenidate missed significantly fewer work hours owing to health reasons and worked significantly more hours. After 4 weeks, 64% of patients reported that methylphenidate improved their cancer-related fatigue, and 58% wanted to continue treatment. Significant difference in IL-6R (positive), IL-10 (negative) and TNFα (positive) was noted between the methylphenidate and the placebo group. Discussion Low-dose methylphenidate did not improve cancer-related fatigue. Patients taking methylphenidate had better cognition and were able to work more hours. Patients tolerated methylphenidate well, and a majority felt better and wanted to continue treatment. PMID:24445757

    Recent studies suggest that the ability of estradiol to enhance cognitive performance diminishes with age and/or time following loss of ovarian function. We hypothesize that this is due, in part, to a decrease in basal forebrain cholinergic function. This study tested whether donepezil, a cholinesterase inhibitor, could restore estradiol effects on cognitive performance in aged rats that had been ovariectomized as young adults. Rats were ovariectomized at 3 months of age, and then trained on a delayed matching to position (DMP) T-maze task, followed by a configural association (CA) operant condition task, beginning at 12–17 or 22–27 months of age. Three weeks prior to testing, rats started to receive either donepezil or vehicle. After one week, half of each group also began receiving estradiol. Acclimation and testing began seven days later and treatment continued throughout testing. Estradiol alone significantly enhanced DMP acquisition in middle-aged rats, but not in aged rats. Donepezil alone had no effect on DMP acquisition in either age group; however, donepezil treatment restored the ability of estradiol to enhance DMP acquisition in aged rats. This effect was due largely to a reduction in the predisposition to adopt a persistent turn strategy during acquisition. These same treatments did not affect acquisition of the CA task in middle-aged rats, but did have small but significant effects on response time in aged rats. The data are consistent with the idea that estrogen effects on cognitive performance are task specific, and that deficits in basal forebrain cholinergic function are responsible for the loss of estradiol effect on DMP acquisition in aged ovariectomized rats. In addition, the data suggest that enhancing cholinergic function pharmacologically can restore the ability of estradiol to enhance acquisition of the DMP task in very old rats following long periods of hormone deprivation. Whether donepezil has similar restorative effects on other

    The prevalence of trimethoprim (TMP) and sulfamethoxazole (SMX) resistance in commensal E. coli from pigs was tested in this study. E. coli was derived from three groups of piglets in successive stages of metaphylactic therapy and from two groups of sows 10 and 18 weeks after the treatment. MIC values of TMP and SMX were determined for a total of 352 strains. The presence of resistance genes (dfrA1, dfrA5, dfrA7, dfrA12, dfrA17, sul1, sul2, sul3) and class 1 and 2 integron-associated dfrA gene cassettes was tested. Resistance to TMP was very high during the administration of the antimicrobial (from 97 to 100%) and amounted to 86% and 69% in the post-exposure period; MIC > 32 mg/L. The isolates from all groups of pigs were resistant to sulfamethoxazole, with MIC > 1028 mg/L. The dfrA1 and sul1 genes (as part of integrons) dominated in E. coli from piglets, but the dfrA12 and sul1 genes were prevalent in E. coli from sows. Coexistence of the different dfrA genes was detected in 71 isolates from all groups of swine. Transcription analysis revealed that most of these genes were not transcribed, particularly gene cassettes of class 1 integrons. The research revealed a high level of resistance associated with the metaphylactic treatment, persistence and circulation of resistance in bacterial populations. Diverse genetic background with multiple and not transcribed resistance genes was observed. PMID:25689993

    Enzyme replacement therapy (ERT) with exogenous glucocerebrosidase is indicated to treat symptomatic Gaucher disease (GD), a rare, inherited metabolic disorder. ERT with velaglucerase alfa, which is produced in a human cell line using gene activation technology, was studied in a 12-month phase III trial in Japanese patients with type 1 or 3 GD who were switched from imiglucerase ERT (n=6); the current, open-label, 12-month extension study was designed to assess longer-term safety and efficacy. Two adult and three pediatric patients (aged <18years) were enrolled into the extension study. Every-other-week intravenous infusions were administered for 63-78weeks at average doses between 51.5 and 60.7units/kg. Three non-serious adverse events were considered related to velaglucerase alfa treatment, but no patient discontinued from the study. Six serious but non-drug-related adverse events were reported. No patient tested positive for anti-velaglucerase alfa antibodies. Hemoglobin concentrations, platelet counts, and liver and spleen volumes (normalized to body weight) in these patients were generally stable over a cumulative 24-month period from the baseline of the parent trial. The data suggest that velaglucerase alfa was well tolerated and maintained clinical stability in Japanese GD patients over 2years after switching from imiglucerase.

    The properties of periodized Daubechies wavelets on [0,1] are detailed and contrasted against their counterparts which form a basis for L{sup 2}(R).

    Most research examining buprenorphine has been conducted with heroin users. Few studies have examined buprenorphine pharmacotherapy for prescription opioid users. Data were from a randomized controlled trial of behavioral treatment provided for 16weeks on a platform of buprenorphine pharmacotherapy and medication management. We compared heroin (H, n=54), prescription opioid (PO, n=54) and combination heroin+prescription opioid (POH, n=71) users to test the hypothesis that PO users will have better treatment outcomes compared with heroin users. The PO group provided more opioid-negative urine drug screens over the combined treatment period (PO:70%, POH:40%, H:38%, p<0.001) and at the end of the combined treatment period (PO:65%, POH:31%, H:33%, p<0.001). Retention was lowest in the H group (PO:80%, POH:65%, H:57%, p=0.039). There was no significant difference in buprenorphine dose between the groups. PO users appear to have better outcomes in buprenorphine pharmacotherapy compared to those reporting any heroin use, confirming that buprenorphine pharmacotherapy is effective in PO users.

    Various cages are constructed by using three types of caps: f-cap (derived from spherical fullerenes by deleting zones of various size), kf-cap (obtainable by cutting off the polar ring, of size k), and t-cap ("tubercule"-cap). Building ways are presented, some of them being possible isomerization routes in the real chemistry of fullerenes. Periodic cages with ((5,7)3) covering are modeled, and their constitutive typing enumeration is given. Spectral data revealed some electronic periodicity in fullerene clusters. Semiempirical and strain energy calculations complete their characterization. PMID:15807490

    Background: Chronic subdural hematoma (CSDH) is frequent pathology in neurosurgical practice. The aim of this study is to present the first series of patients with CSDH, who got surgically treated in Clinic of Neurosurgery, University Clinical Center of Kosovo. Materials and Methods: This is a retrospective study that included 137 patients with CSDH who had been treated during the period 2008–2012. The data were collected and analyzed from the archives and protocols of the University Clinical Center of Kosovo. Patients were analyzed in many aspects such as age, gender, etiological factors, clinical features, localization, diagnoses, methods of surgical interventions, recurrences and mortality of patients. Results: From 137 patients with CSDH, 106 (77.3%) were males and 31 (22.7%) females. Average age of patients was 62.85 years. Analyzed according to the decades, the highest number of causes with CSDH was between 70 and 79 years (46%). The head trauma has been responsible for CSDH in 88 patients (64.3%), while the main symptom was headache (92 patients or 67.1%). One burr-hole trepanation with closed drainage system has been used in majority of cases (in 101 patients or 73.7%). The recurrence of CSDH was 6.5%, whereas mortality 2.9%. Conclusion: CSDH is more common in elderly patients. The male-female ratio is 3.4:1. Like other authors we also think that treatment with one burr-hole and drainage is a method of choice, because of its simplicity and safety. PMID:25883478

    Periodic polymers can be made by self assembly, directed self assembly and by photolithography. Such materials provide a versatile platform for 1, 2 and 3D periodic nano-micro scale composites with either dielectric or impedance contrast or both, and these can serve for example, as photonic and or phononic crystals for electromagnetic and elastic waves as well as mechanical frames/trusses. Compared to electromagnetic waves, elastic waves are both less complex (longitudinal modes in fluids) and more complex (longitudinal, transverse in-plane and transverse out-of-plane modes in solids). Engineering of the dispersion relation between wave frequency w and wave vector, k enables the opening of band gaps in the density of modes and detailed shaping of w(k). Band gaps can be opened by Bragg scattering, anti-crossing of bands and discrete shape resonances. Current interest is in our group focuses using design - modeling, fabrication and measurement of polymer-based periodic materials for applications as tunable optics and control of phonon flow. Several examples will be described including the design of structures for multispectral band gaps for elastic waves to alter the phonon density of states, the creation of block polymer and bicontinuous metal-carbon nanoframes for structures that are robust against ballistic projectiles and quasi-crystalline solid/fluid structures that can steer shock waves.

    Two dose levels of citalopram, 10-30 mg and 20-60 mg, were compared with imipramine, 50-150 mg, in depressed patients treated in general practice. This was a multicentre study carried out in Denmark, Sweden, Norway, and Finland. The duration of treatment was 6 weeks with an optional continuation phase of a further 16 weeks. The patients were assessed by means of the Hamilton Rating Scale for Depression (HAMD), Clinical Global Impressions (CGI), and a visual analogue self-rating scale for depression. Observed and spontaneously reported adverse events were recorded. A total of 472 patients were entered into the study and 400 patients completed the 6 week trial period. A total of 297 patients completed the optional 22 week double-blind period. A clear reduction of the HAMD total scores was seen in all three treatment groups with no significant differences between groups. A reduction of the HAMD anxiety factor and sleep factor scores was also seen with no significant differences between treatments. The imipramine-treated patients showed a higher frequency of adverse events, especially the anticholinergic type, than citalopram-treated patients. Most patients entered into the continuation phase remained well. PMID:8021437

  5. Bone Matrix Composition Following PTH Treatment is Not Dependent on Sclerostin Status.

    Sclerostin and parathyroid hormones are strong negative and positive regulators of bone formation, respectively. The anabolic response induced by intermittent (iPTH) treatment is sclerostin status-dependent. However, the interaction between sclerostin and iPTH at the matrix level is unknown. The goal of the current study was to determine if iPTH treatment affects matrix composition and, if so, whether these effects are dependent on sclerostin status. Humeral trabecular and cortical bone sites from 16 week old male wild-type (WT) and sclerostin knockout (KO) mice, which had been treated with vehicle or iPTH from age 10-16 weeks, were examined by micro-computed tomography (µCT) to measure bone volume, backscatter scanning electron microscopy (bSEM) to assess global mineralization, and Fourier transform infrared microspectroscopy (FTIRM) to examine matrix composition (mineral-to-matrix ratio, crystallinity, collagen cross-link ratio, and carbonate substitution). The FTIRM measurements were restricted to the tissue formed during the 6-week treatment period. iPTH treatment led to increased trabecular bone volume (p < 0.001) and this effect was much greater in KO mice than WT mice (interaction effect, p < 0.001). iPTH treatment led to reduced trabecular crystallinity (p = 0.047), increased cortical bone area (p < 0.001), decreased cortical bone crystallinity (p = 0.002) and increased cortical bone collagen cross-linking (p = 0.028) to similar degrees in both WT and KO mice. Compared to WT mice, sclerostin KO mice had higher trabecular and cortical bone mass (p < 0.001) and lower mineral-to-matrix ratio in the trabecular (p = 0.010) and cortical (p = 0.016) compartments. Thus, iPTH-induced changes in bone mass are dependent upon sclerostin status in the trabecular compartment, but not in the cortical compartment. In contrast, iPTH-induced changes in matrix composition are sclerostin-independent in both trabecular and cortical compartments. PMID:26514840

    Psychosocial interventions for atypical depression (AD) have been relatively ignored in the clinical research literature, despite evidence that the atypical subtype of major depression is marked by earlier age of onset, longer duration of mood episode, greater symptom severity, and poorer response to pharmacologic treatment. Given the symptom profile of AD, which is characterized by mood reactivity, psychomotor slowing, and interpersonal withdrawal, we argue that a behavioral activation (BA) intervention may be particularly well suited to this population. As an initial exploration of this hypothesis, the current study presents preliminary outcome data from 10 outpatients with AD who participated in an open pilot trial of BA over a 16-week period. Overall, results provide encouraging preliminary support for the feasibility, acceptability, and efficacy of BA for AD, with significant reductions in depressive symptoms and associated improvements in functional impairment and behavioral activation level. Study results are discussed in the context of existing treatments for AD, and areas for future treatment development are highlighted. PMID:21507998

    Mice were X-irradiated on day 14, 15 or 16 of gestation with 1.0 Gy. This did not result in an increased tumour frequency in the offspring until 12 months. Mice treated with ethylnitrosourea (ENU) (45 mg/kg) on these gestation days developed a significantly increased tumour frequency in the lungs and liver, and in the ovaries after treatment on day 15 of gestation. Additionally this experiment was the first to show that ENU treatment on gestation day 14, 15 or 16 results in haemangiosarcomas of the subcutis at a low incidence (2.0, 2.4, 2.6 per cent). After combined treatment with these two agents in the sequence X+ENU and an interval of 4 h, a significantly increased incidence rate of animals with tumours was observed in the offspring treated on gestation day 14 or 16. Moreover, the treatment on gestation day 16 exhibited the highest tumour frequency per examined animal (5.7) of all treatment groups. This result is due to a relatively uniform increase of all tumor types. Within this pattern, the frequency of liver tumours was most marked. The diagnosed liver tumours were significantly augmented after X+ENU treatment on day 16. In the reverse sequence (ENU+X), the total tumour outcome was not significantly altered compared with the effects of ENU alone. However, detailed analysis also showed a significant augmentation of the liver tumour frequency with treatment on day 15. PMID:3496295

    Childhood/adolescent antipsychotic drug (APD) use is exponentially increasing worldwide, despite limited knowledge of the long-term effects of early APD treatment. Whilst investigations have found that early treatment has resulted in some alterations to dopamine and serotonin neurotransmission systems (essential to APD efficacy), there have only been limited studies into potential long-term behavioural changes. This study, using an animal model for childhood/adolescent APD treatment, investigated the long-term effects of aripiprazole, olanzapine and risperidone on adult behaviours of male and female rats. Open-field/holeboard, elevated plus maze (EPM), social interaction and forced swim (FS) tests were then conducted in adult rats. Our results indicated that in the male cohort, early risperidone and olanzapine treatment elicited long-term hyper-locomotor effects (open-field/holeboard and FS tests), whilst a decrease in depressive-like behaviour (in FS test) was observed in response to olanzapine treatment. Furthermore, anxiolytic-like behaviours were found following testing in the open-field/holeboard and EPM in response to all three drug treatments. Effects in the female cohort, however, were to a far lesser extent, with behavioural attributes indicative of an increased depressive-like behaviour and hypo-locomotor activity exhibited in the FS test following early risperidone and olanzapine treatment. These results suggest that various APDs have different long-term effects on the behaviours of adult rats. PMID:26577063

    The treatment approach to patients 80 years of age and older with gastroesophageal cancer at Baylor Scott and White in Temple, Texas, has historically favored conservative measures in the form of palliation and observation. To evaluate this trend in practice, the administered treatments and subsequent patient outcomes of this group were retrospectively reviewed. The study group included all patients 80 years of age and older with a diagnosis of gastroesophageal cancer seen at our facility between 1991 and 2010. Of the 117 cases, 49% received none of the available treatment modalities. The median overall survival (OS) of patients who received treatment, however, was significantly longer than the OS of those who did not, regardless of modality. Specifically, surgical intervention offered an almost double median OS compared with no therapy (6.8 vs. 3.9 months, respectively; P = 0.02); chemotherapy, an almost 4-fold OS benefit (14.8 vs. 3.9 months; P = 0.03); and radiation therapy, a >3-fold OS benefit (11.1 vs. 3.5 months; P = 0.04). These results further substantiate chronological age as an inaccurate predictor of treatment benefit, and age alone should not dictate the administration or withholding of available treatment options.

    This study examines the performance of an anaerobic fixed-film bioreactor under seasonal operating conditions prevailing in medium and small size Tequila factories: start-up, normal operation and particularly, during the restart-up after a long stop and starvation period. The proposed start-up procedure attained a stable biofilm in a rather short period (28 days) despite unbalanced COD/N/P ratio and the use of non-acclimated inoculum. The bioreactor was restarted-up after being shut down for 6 months during which the inoculum starved. Even when biofilm detachment and bioreactor clogging were detected at the very beginning of restart-up, results show that the bioreactor performed better as higher COD removal and methane yield were attained. CE-SSCP and Q-PCR analyses, conducted on the biofilm prokaryotic communities for each operating condition, confirmed that the high COD removal results after the bioreactor clogging and the severe starvation period were mainly due to the stable archaeal and resilient bacterial populations.

    A case of thyrotoxic periodic paralysis is reported in a Hispanic man with an unusual recurrence six weeks after radioactive iodine treatment. Thyrotoxic periodic paralysis has now been well characterized in the literature: it occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion, with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is establishing a euthyroid state. The pathophysiology is still controversial, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself.

    Although intralesional meglumine antimoniate (MA) infiltration is considered an option for cutaneous leishmaniasis (CL) therapy and is widely used in the Old World, there have been few studies supporting this therapeutic approach in the Americas. This study aims to describe outcomes and adverse events associated with intralesional therapy for CL. This retrospective study reviewed the experience of a Brazilian leishmaniasis reference centre using intralesional MA to treat 31 patients over five years (2008 and 2013). The median age was 63 years (22-86) and the median duration time of the lesions up to treatment was 16 weeks. In 22 patients (71%), intralesional therapy was indicated due to the presence of contraindications or previous serious adverse events with systemic MA. Other indications were failure of systemic therapy or ease of administration. Intralesional treatment consisted of one-six infiltrations (median three) for a period of up to 12 weeks. The initial (three months) and definitive (six months) cure rates were 70.9% and 67.7%, respectively. Most patients reported mild discomfort during infiltration and no serious adverse events were observed. In conclusion, these results show that the intralesional MA efficacy rate was very similar to that of systemic MA treatment, and reinforce the need for further studies with adequate design to establish the efficacy and safety of this therapeutic approach.

    Treatment of adolescents with growth hormone deficiency (GHD) during the transition period is a controversial issue. This paper is a contribution from the Italian community of paediatric and adult endocrinologists surveyed in a Delphi panel. The Delphi method is a structured communication technique, originally developed as a systematic, interactive forecasting method that relies on a panel of experts. The experts answer questionnaires in two or more rounds. There was substantial agreement on the definition of the problems associated with the diagnosis and treatment of adolescents with GHD in the transition period, as well as on the identification of the controversial issues which need further studies. There is general consensus on the need of re-testing all isolated idiopathic GHD after at least 30-day withdrawn from treatment, while in patients with multiple pituitary deficiency and low IGF-I levels there is generally no need to re-test. In patients with permanent or confirmed GHD, a starting low rhGH dose (0.01-0.03 mg per day) to be adjusted according to IGF-I concentrations is also widely accepted. For those continuing treatment, the optimal therapeutic schedule to obtain full somatic maturation, normalization of body composition and bone density, cardiovascular function and Quality of Life, need to be evaluated.

    This study assessed clinical scenarios of continuing monoclonal antibody (mAb) treatment for (+)-methamphetamine (METH) addiction, and the implications of missing or discontinuing this therapy. We hypothesized that chronic anti-METH mAb7F9 (METH KD = 9 nM) treatment of rats could significantly decrease METH-induced behaviors; even with repeated METH challenges, use of METH doses in excess of mAb binding sites, and after discontinuing mAb treatment which results in a 10-fold reduction in mAb7F9 serum concentrations. Male Sprague Dawley rats (n=6/group) were treated with i.v. saline or a loading dose of mAb7F9 to achieve instant steady-state conditions followed by two weekly (141 mg/kg) doses ending on day 14. METH (0.56 mg/kg) was administered four hours and three days after each saline or mAb7F9 treatment, and on day 21. This produced locomotion and rearing behavior that lasted about 120 min in control rats. In mAb7F9 treated rats, METH-induced distance traveled was significantly reduced from 60–120 min (P<0.05) on days 0–21 and rearing was significantly reduced from 60–120 min on days 0–17. METH serum concentrations determined 5 hrs after METH dosing was significantly increased in mAb7F9-treated rats after all METH challenges. On days 24 and 28 (the final day), the rats were administered a 3-fold higher METH dose (1.68 mg/kg). MAb7F9 treated rats showed a substantially earlier termination of the METH-induced locomotion on both days, even though the METH dose exceeded mAb7F9’s binding capacity. METH brain concentrations determined 5 hrs after METH on day 28 were also significantly decreased in mAb7F9-treated rats. In conclusion, over one month, mAb7F9 significantly and continuously bound METH and reduced METH-induced locomotor effects even after discontinuation of mAb treatment and challenge with higher METH doses.

    The present aimed to develop a hormonal therapy based on the insertion of a progesterone (P4) insert (PI) during 10 d plus an estradiol injection (E2) at PI removal before the onset of breeding of beef heifers. In Exp. 1, the plasma P4 profile of prepubertal heifers showed that the insertion of a PI or 24 d previously used P4 insert (UPI) sustained plasma P4 above 1 ng/mL for at least the first 7 d of the treatment. In Exp. 2 there was no positive effect of additional estradiol benzoate (EB) administered at the insertion of UPI on the proportion of heifers with a corpus luteum (CL/Treated) 30 d after UPI removal [UPI + EB = 85.3%(a) (n = 134); EB + UPI + EB = 80.8%(a) (n = 125)]; however, both were greater (P < 0.0001) than the Control group [60.3%(b) (n = 129)]. In Exp. 3, a positive effect (P=0.01) of UPI treatment and both E2 supplementations [EB and estradiol cypionate (EC); P = 0.10] at the UPI removal was observed on CL/Treated [Control = 42.5%(b) (n = 94); UPI = 58.5%(a) (n= 130); UPI + EB = 64.0%(a) (n = 128); UPI + EC = 67.2%(a) (n = 128)]. However, greater pregnancy per treated heifer (P/Treated) following artificial insemination (AI) upon estrus detection was achieved when EC was applied [Control = 20.2%(b); UPI = 29.2%(ab); UPI + EB = 26.6%(b); UPI + EC = 36.7%(a)]. In Exp. 4, the treatment prior to the timed AI (TAI) tended to improve pregnancy per TAI [P/AI; Control 43.6% (n = 298) vs. UPI+EC 51.9% (n = 342); P = 0.08], but increased P/Treated [26.5% vs. 43.3%; P < 0.001]. Thus, UPI + EC treatment were efficient in increasing the CL/Treated, tended to improve the P/AI and consequently enhanced P/Treated of zebu beef heifers. PMID:26169688

    Background Fluctuations of good days and bad days—in physical symptoms and emotional states—are common for individuals with chronic illness. This pilot study examines these fluctuations during bodywork treatment. Purpose We analyzed changes in daily self-reports over a period of five months for five individuals who received weekly treatments of Rosen Method Bodywork (RMB), which uses touch and words to enhance body awareness of physical sensations and emotional states. Subjects and Design Five subjects (aged 31–56) who had chronic low back pain (CLBP) received 16 weekly treatments given by three experienced RMB practitioners. Measures Pre- and posttreatment assessments covered demographics, disability, and pain. Clients also completed daily bedtime assessments of pain, fatigue, emotional state, and sense of control during the entire treatment period. Results All clients reported reductions in pain and/or disability in post- compared to pretreatment. In spite of a high level of day-to-day variability in the daily assessments, there were significant reductions in pain and fatigue, and significant increases in positive emotional state and sense of control across the treatment period. In reaching this end, however, some clients had slow and steady improvements, some improved more rapidly, while others got worse before they got better. Conclusions The natural course of healing—with its inevitable fluctuations in symptoms—is part of a process leading to successful treatment outcomes. Rosen Method Bodywork may be especially helpful in developing and accepting both sensory and emotional body awareness changes that facilitate overall improvement. PMID:24000305

    The use of fixed combinations in acne vulgaris (acne) is very common, however comparative clinical trial data are limited. Cutaneous tolerability can influence patient compliance, and concerns about skin irritation with topical acne treatments have lead to a number of comparative split-face studies.
    Recently, a new fixed combination product was introduced (clin 1.0%-BP 3.75% gel) that was shown to be effective in reducing both inflammatory and noninflammatory lesions in moderate to severe acne. Here, we assess the tolerability of clin 1.0%-BP 3.75% gel compared with adap 0.1%-BP 2.5% gel in healthy volunteers with no apparent facial redness or dryness over 21-days, using a split-face methodology.
    Especially over the first two weeks of treatment, clin 1.0%-BP 3.75% gel was more tolerable than adap 0.1%-BP 2.5% gel, with statistically significant differences in cumulative change from baseline starting as early as day 8 (dryness) and day 9 (erythema), and composite index on days 8-12 and 16. Transepidermal water loss was less with clin 1.0%-BP 3.75% gel, although the difference was not statistically significant.

Design—Since January 1984, ICDs were implanted in 450 patients to evaluate surgical risk, complications and mean survival in relation to patient age; 81 patients (18%) were ⩽ 50 years at the time of ICD implant, 254 patients (56%) were between 51 and 64 years, and the remaining 115 (26%) were ⩾ 65 years. Epicardial lead systems were implanted in 209 patients (46%), while transvenous lead systems were implanted in 241 (54%).
Results—13 patients (3%) died perioperatively, more often after epicardial (11 of 209 patients, 5%) than after transvenous ICD implantation (one of 241 patients, < 1%) (p < 0.05). During a mean (SD) follow up of 28 (24) months (range < 1 to 114 months), 90 patients (20%) died. Of these, nine (2%) died from sudden arrhythmic death; five (1%) died suddenly, probably as a result of non-arrhythmic causes; 55 (12%) died from other cardiac causes (congestive heart failure, myocardial infarction); and 21 (5%) died from non-cardiac causes. The three, five, and seven year survival for arrhythmic mortality was 95% in patients ⩽ 50 years compared with a three year survival of 93% and a five and seven year survival of 91% in patients of 51 to 64 years, and a three, five, and seven year survival of 99% in patients ⩾ 65 years. 362 patients (80%) received ICD discharges (21 (43) shocks per patient), with a similar incidence among all three patient groups (⩽ 50 years, 80%; 51 to 64 years, 81%; ⩾ 65 years, 79%). The time interval between ICD implant and the first ICD treatment was shorter in patients ⩾ 65 years (8 (8) months) than in patients between 51 and 64 years (11 (14) months) or ⩽ 50 years (11 (11) months) (p < 0.05). Survival time following first appropriate shock was 30 (24) months in patients ⩽ 50 years, 30 (26

    Approximately 750 leiomyomas of 250 symptomatic patients were treated by LITT over a five-year period. Only 12% were lost to follow-up. Most were treated by a combination of the KTP/YAG laser, rarely by one or the other alone, and a few with the diode laser. The fiber optic was inserted 2 cm apart and, depending on the size of the tumor, 480 - 20,000 Joules were required. Most were treated laparoscopically but very large myomas were treated percutaneously under ultrasound control. Symptoms were nearly always relieved and the six failures were found to be due to unrecognized adenomyosis and other associated pathology. Half the patients complaining of infertility became pregnant and, in those whose only pathology had been leiomyomas it approached 90%. Vaginal delivery was not found to be contraindicated. Finally, oestrogen receptors and epidermal growth factor were found to be destroyed. It is concluded that LITT enables leiomyomas of all sizes and locations to be treated by a minimally invasive method with preservation of the uterus.

  20. The classical electrostatic periodic table, capacitance of few electron dielectric spheres and a novel treatment of one- and two-electron finite quantum wells

    Lafave, Tim, Jr.

    The centerpiece of this dissertation is the discovery of the classical electrostatic periodic table of elements through non-linear ground state energies coincident with atomic shell-filling resulting from symmetry properties of discrete electrons constrained by a spherically-symmetric system. The time-independent electrostatic equilibrium configuration of few electrons confined to a large classical dielectric sphere is obtained by minimization of the total interaction energy. The interactions model yields more than twice the energy predicted by the classical Gauss model. Each N-electron system is proposed as a unique phase characterized by its symmetry properties. A new mono-phasic capacitance definition of dielectric spheres is derived from the fundamental relation Q=CV. Large differences from the Gauss model are obtained for few-electron systems, but convergence is found in the metallic limit. Of particular significance is the means by which symmetry-dependent properties of atomic-scale devices may be exploited by controlling the internal architecture of charge distributions. This work will be useful to modeling of many-electron chemical and biological systems, such as macromolecules, owing largely to symmetry differences between the Gauss model and the interactions model. The foundation upon which all Nature rests is the symmetry of fundamental particles.

    To reduce HIV incidence, prevention programs centered on the use of antiretrovirals require scaling-up HIV testing and counseling (HTC). Home-based HTC services (HBHTC) increase HTC coverage, but HBHTC has only been evaluated during one-off campaigns. Two years after an initial HBHTC campaign (“round 1”), we conducted another HBHTC campaign (“round 2”) in Likoma (Malawi). HBHTC participation increased during round 2 among women (from 74% to 83%, p<0.01). New HBHTC clients were recruited, especially at ages 25 and older. Only 6.9% of women but 15.9% of men remained unreached by HBHTC after round 2. HIV prevalence during round 2 was low among clients who were HIV-negative during round 1 (0.7%), but high among women who first tested during round 2 (42.8%). The costs per newly diagnosed infection increased significantly during round 2. Periodically conducting HBHTC campaigns can further increase HTC, but supplementary interventions to enroll individuals not reached by HBHTC are needed. PMID:23180155

    Background. Vaginal infections are common, frequently recur, and may increase women's risk for sexually transmitted infections (STIs). We tested the efficacy of a novel regimen to prevent recurrent vaginal infections. Methods. Human immunodeficiency virus (HIV)–negative women 18–45 years old with 1 or more vaginal infections, including bacterial vaginosis (BV), vulvovaginal candidiasis (VVC), or Trichomonas vaginalis (TV), were randomly assigned to receive vaginal suppositories containing metronidazole 750 mg plus miconazole 200 mg or matching placebo for 5 consecutive nights each month for 12 months. Primary endpoints, evaluated every 2 months, were BV (Gram stain) and VVC (positive wet mount and culture). Results. Participants (N = 234) were randomly assigned to the intervention (N = 118) or placebo (N = 116) arm. Two hundred seventeen (93%) women completed an end-of-study evaluation. The intervention reduced the proportion of visits with BV compared to placebo (21.2% vs 32.5%; relative risk [RR] 0.65, 95% confidence interval [CI] .48–.87). In contrast, the proportion of visits with VVC was similar in the intervention (10.4%) versus placebo (11.3%) arms (RR 0.92, 95% CI .62–1.37). Conclusions. Monthly treatment with intravaginal metronidazole plus miconazole reduced the proportion of visits with BV during 12 months of follow-up. Further study will be important to determine whether this intervention can reduce women's risk of STIs. PMID:25526757

    Aims This study documented the treatment cascade for engagement in care and abstinence at treatment exit as well as examined correlates of these outcomes for the first certified Matrix Model® substance abuse treatment site in Sub-Saharan Africa. Design This retrospective chart review conducted at a resource-limited community clinic in Cape Town, South Africa, assessed treatment readiness and substance use severity at treatment entry as correlates of the number of sessions attended and biologically confirmed abstinence at treatment exit among 986 clients who initiated treatment from 2009–2014. Sociodemographic and clinical correlates of treatment outcomes were examined using logistic regression, modeling treatment completion and abstinence at treatment exit separately. Results Of the 2,233 clients who completed screening, approximately 44% (n = 986) initiated treatment. Among those who initiated treatment, 45% completed at least four group sessions, 30% completed early recovery skills training (i.e., at least eight group sessions), and 13% completed the full 16-week program. Approximately half (54%) of clients who provided a urine sample had negative urine toxicology results for any substance at treatment exit. Higher motivation at treatment entry was independently associated with greater odds of treatment completion and negative urine toxicology results at treatment exit. Conclusions Findings provide initial support for the successful implementation the Matrix Model in a resource-limited setting. Motivational enhancement interventions could support treatment initiation, promote sustained engagement in treatment, and achieve better treatment outcomes. PMID:26816208

    Diabetes mellitus (DM) is a significant international health concern affecting more than 387 million individuals. A diabetic person has a 25% lifetime risk of developing a diabetic foot ulcer (DFU), leading to limb amputation in up to one in six DFU patients. Low-level light therapy (LLLT) uses low-power lasers or light-emitting diodes to alter cellular function and molecular pathways, and may be a promising treatment for DFU. The goal of this systematic review is to examine whether the clinical use of LLLT is effective in the healing of DFU at 12 and 20 weeks in comparison with the standard of care, and to provide evidence-based recommendation and future clinical guidelines for the treatment of DFU using LLLT. On September 30, 2015, we searched PubMed, EMBASE, CINAHL, and Web of Science databases using the following terms: "diabetic foot" AND "low level light therapy," OR "light emitting diode," OR "phototherapy," OR "laser." The relevant articles that met the following criteria were selected for inclusion: randomized control trials (RCTs) that investigated the use of LLLT for treatment of DFU. Four RCTs involving 131 participants were suitable for inclusion based upon our criteria. The clinical trials used sham irriadiation, low dose, or nontherapeutic LLLT as placebo or control in comparison to LLLT. The endpoints included ulcer size and time to complete healing with follow-up ranging from 2 to 16 weeks. Each article was assigned a level of evidence (LOE) and graded according to the Oxford Center for Evidence-based Medicine Levels of Evidence Grades of Recommendation criteria. Limitations of reviewed RCTs include a small sample size (N < 100), unclear allocation concealment, lack of screening phase to exclude rapid healers, unclear inclusion/exclusion criteria, short (<30 days) follow-up period, and unclear treatment settings (wavelength and treatment time). However, all reviewed RCTs demonstrated therapeutic outcomes with no adverse events using LLLT for

    Purpose Our study aimed to examine the relationship between intelligence and health-related quality of life (HRQOL) in children (6-13 years old) diagnosed as having a brain tumor. Materials and Methods We administered a Korean version of the Wechsler Intelligence Scale for Children-III, the Pediatric Quality of Life Inventory, version 4.0 (PedsQL), the Korean version of the Parenting Stress Index-Short Form, and the Korean Version of the Parenting Sense of Competence (K-PSOC) scale before or after initial radiotherapy (T1) and after treatment termination (T2). In total, 13 patients completed both the T1 and T2 interviews. Results Scores significantly declined between T1 and T2 on the full-scale intelligence quotients (FIQ), verbal intelligence quotients (VIQ), performance intelligence quotients (PIQ), similarity and coding tests, as well as the K-PSOC, which measures parental anxiety. FIQ scores at T1 were correlated with the self-reported PedsQL total scores (r=0.739) and the parent proxy-report PedsQL scores for school functioning (r=0.706) at T2. Also, the FIQ scores at T2 were correlated with the self-reported PedsQL total scores (r=0.748) and scores for physical health (r=0.728) at T2. Conclusion The cognitive ability and intelligence level of the patients significantly declined between on and off treatment periods, and higher intelligence functioning at both on and off treatment was correlated with long-term higher HRQOL. Further investigations that monitor intelligence, HRQOL and parenting stress over a longer period, using a greater number of participants, are needed. PMID:23364961

    Periodical cicadas (Magicicada spp.) in the USA are famous for their unique prime-numbered life cycles of 13 and 17 years and their nearly perfectly synchronized mass emergences. Because almost all known species of cicada are non-periodical, periodicity is assumed to be a derived state. A leading hypothesis for the evolution of periodicity in Magicicada implicates the decline in average temperature during glacial periods. During the evolution of periodicity, the determinant of maturation in ancestral cicadas is hypothesized to have switched from size dependence to time (period) dependence. The selection for the prime-numbered cycles should have taken place only after the fixation of periodicity. Here, we build an individual-based model of cicadas under conditions of climatic cooling to explore the fixation of periodicity. In our model, under cold environments, extremely long juvenile stages lead to extremely low adult densities, limiting mating opportunities and favouring the evolution of synchronized emergence. Our results indicate that these changes, which were triggered by glacial cooling, could have led to the fixation of periodicity in the non-periodical ancestors. PMID:26365061

    The major branch of the Seine river from the confluence with the Marne river to the entrance of the estuary is deeply affected by the release of wastewater from the huge Paris agglomeration. In the first years of 2000, the largest part of the effluents were still discharged at the Seine-Aval (Achères) treatment plant with only a standard, low residence time, activated sludge treatment, thus releasing a high ammonium load. NH4 concentration as high as 7 mgN/l were frequently observed downstream from Paris agglomeration. Cébron et al. (2003, 2005) and Garnier et al. 2007 described in details how this massive reduced nitrogen concentrations triggered the growth of nitrifying bacteria, already present in the upstream Seine and Marne rivers, but also brought in large amount by the effluents of the wastewater treatment plant themselves. The decrease of ammonium concentration was slow, however, and was only completed 200 km downstream, in the upper estuarine area, where it causes a severe oxygen deficiency. Since 2007, important changes occurred in the treatment of nitrogen in the Parisian wastewater purification plants. In 2007, the Seine-Aval plant treated up to 90% of the ammonium contained in wastewater through nitrification, and 30% of the total supply of nitrates is treated by denitrification. These modifications have of course favorably affected the water quality of the Seine river: ammonium concentrations are reduced by a factor of 5 and the area of oxygen depletion in the upstream estuary is no more observed. However, nitrites, still released in the effluents, are a matter of concern for the water quality of the Seine downstream from Paris. Using measurements of potential microbial activities carried out with the same experimental protocol for the 2000-2003 and 2012-2013 periods, we here examine and model the dynamics of ammonium oxidizing and nitrite oxidizing microbial populations before and after the implementation of nitrification treatment of Paris

    A systematic literature review and meta-analyses (where appropriate) were performed to update the previous AASM practice parameters on the treatments, both dopaminergic and other, of RLS and PLMD. A considerable amount of literature has been published since these previous reviews were performed, necessitating an update of the corresponding practice parameters. Therapies with a STANDARD level of recommendation include pramipexole and ropinirole. Therapies with a GUIDELINE level of recommendation include levodopa with dopa decarboxylase inhibitor, opioids, gabapentin enacarbil, and cabergoline (which has additional caveats for use). Therapies with an OPTION level of recommendation include carbamazepine, gabapentin, pregabalin, clonidine, and for patients with low ferritin levels, iron supplementation. The committee recommends a STANDARD AGAINST the use of pergolide because of the risks of heart valve damage. Therapies for RLS secondary to ESRD, neuropathy, and superficial venous insufficiency are discussed. Lastly, therapies for PLMD are reviewed. However, it should be mentioned that because PLMD therapy typically mimics RLS therapy, the primary focus of this review is therapy for idiopathic RLS.

    A study protocol is presented for the investigation of meditative movement (MM) as a treatment for pulmonary dysfunction in flight attendants (FA) who were exposed to second-hand cigarette smoke while flying before the smoking ban. The study will have three parts, some of which will run concurrently. The first is a data gathering and screening phase, which will gather data on pulmonary and other aspects of the health of FA, and will also serve to screen participants for the other phases. Second is an exercise selection phase, in which a variety of MM exercises will be taught, over a 16-week period, to a cohort of 20 FA. A subset of these exercises will be selected on the basis of participant feedback on effectiveness and compliance. Third is a 52-week randomized controlled trial to evaluate the effectiveness of a digitally delivered form of the previously selected exercises on a group of 20 FA, as compared with an attention control group. Outcome measures to be used in all three parts of the study include the 6-min walk test as a primary measure, as well as a range of biomarkers, tests, and questionnaires documenting hormonal, cardio-respiratory, autonomic, and affective state.

    Background: Chronic spontaneous urticaria (CSU) has a detrimental effect on patients’ emotional and physical quality of life. Omalizumab, an anti-immunoglobulin E humanized monoclonal antibody, has been shown to be very effective in the treatment of refractory chronic urticaria patients but may not be an economically viable option for all CSU patients. However, we present a case series where a single dose of omalizumab gave sustained relief of symptoms in patients with CSU, which may be an economical option. Aims: The aim of this study is to assess the efficacy of a single dose of omalizumab in the treatment of CSU. Materials and Methods: Four patients of CSU whose disease was not controlled with four times the licensed dose of tablet fexofenadine 180 mg were exhibited one subcutaneous injection of omalizumab and were followed up at 4 weekly intervals for 24 weeks for Weekly Urticaria Activity Score 7 (UAS7) and Dermatology Life Quality Index (DLQI). Results: A sharp decline in UAS7 and DLQI was documented in 7–10 days. The decline was maintained up to 16 weeks in one case and 20 weeks in the other three cases. Both the scores at the end of the follow-up period of 24 weeks were better than the pre-omalizumab scores. Conclusion: The results of this case series indicate the efficacy of a single-dose omalizumab in treating moderate to severe refractory CSU. Further studies are required to identify the minimum frequency of administering omalizumab to effectively control CSU. This would greatly reduce the cost of this novel therapy. PMID:27512204

    Although sprains of the lateral collateral ligaments of the ankle are extremely common, controversy still exists over the proper treatment. Some authors recommend early mobilization of the ankle, others recommend cast immobilization for 1-6 weeks, and others insist that sprains should be treated with primary surgical repair. A critical appraisal of the literature supports the concepts of early mobilization with a proper rehabilitation program. The review of treatment is followed by a discussion of the potential causes of persistent pain and functional instability. PMID:7670975

    Objective This study assessed the efficacy and safety of canakinumab, a fully human anti-interleukin 1β monoclonal antibody, for prophylaxis against acute gouty arthritis flares in patients initiating urate-lowering treatment. Methods In this double-blind, double-dummy, dose-ranging study, 432 patients with gouty arthritis initiating allopurinol treatment were randomised 1:1:1:1:1:1:2 to receive: a single dose of canakinumab, 25, 50, 100, 200, or 300 mg subcutaneously; 4×4-weekly doses of canakinumab (50+50+25+25 mg subcutaneously); or daily colchicine 0.5 mg orally for 16 weeks. Patients recorded details of flares in diaries. The study aimed to determine the canakinumab dose having equivalent efficacy to colchicine 0.5 mg at 16 weeks. Results A dose-response for canakinumab was not apparent with any of the four predefined dose-response models. The estimated canakinumab dose with equivalent efficacy to colchicine was below the range of doses tested. At 16 weeks, there was a 62% to 72% reduction in the mean number of flares per patient for canakinumab doses ≥50 mg versus colchicine based on a negative binomial model (rate ratio: 0.28–0.38, p≤0.0083), and the percentage of patients experiencing ≥1 flare was significantly lower for all canakinumab doses (15% to 27%) versus colchicine (44%, p<0.05). There was a 64% to 72% reduction in the risk of experiencing ≥1 flare for canakinumab doses ≥50 mg versus colchicine at 16 weeks (hazard ratio (HR): 0.28–0.36, p≤0.05). The incidence of adverse events was similar across treatment groups. Conclusions Single canakinumab doses ≥50 mg or four 4-weekly doses provided superior prophylaxis against flares compared with daily colchicine 0.5 mg. PMID:21540198

Methods: A total of 75 patients (mean (SD) age was 52.8 (16.4) years, 76.0% were female) were included in this study conducted between 12 August 2008 and 30 October 2009 in 9 centers across Turkey. The mean change in Hb concentration (g/dL) between baseline (week 0) and the efficacy evaluation period (EEP) was the primary efficacy parameter evaluated in three consecutive periods including a dose titration period (DTP; with initial 1.2 μg/kg dose of C.E.R.A., subcutaneously, 28 weeks), EEP (8 weeks) and a long-term safety period (16 weeks). Results: Our analysis revealed an improvement in Hb levels from baseline value of 9.4 (0.4) g/dL to time adjusted average level of 11.4 (0.7) g/dL in EEP in the per protocol (PP) population and from 9.3 (0.5) g/dL to 11.1 (1.0) g/dL in intent-to-treat (ITT) population. Mean (SD) change in Hb levels from baseline to EEP was 2.0 (0.7) g/dl in the PP population (primary endpoint) and 1.7 (1.1) g/dL in the ITT population. The percentage of patients whose Hb concentrations remained within the target range of 10.0–12.0 g/dL throughout the EEP was 43.9% (95% CI: 28.5–60.3%) in the PP population and 38.7% (95% CI: 27.6% to 50.6%) in the ITP population. A total of 206 adverse events (AE) were reported in 77.0% of patients with hypertension (20%) as the most frequent AE. Conclusion: Once-monthly subcutaneous C.E.R.A. administration is effective and safe in the treatment of anemia in pre-dialysis patients with CKD, who are not currently treated with ESAs.

    This paper deals with the analysis of time series with respect to certain known periodicities. In particular, we shall present a fast method aimed at detecting periodic behavior inherent in noise data. The method is composed of three steps: (1) Non-noisy data are analyzed through spectral and wavelet methods to extract specific periodic patterns of interest. (2) Using these patterns, we construct an optimal piecewise constant wavelet designed to detect the underlying periodicities. (3) We introduce a fast discretized version of the continuous wavelet transform, as well as waveletgram averaging techniques, to detect occurrence and period of these periodicities. The algorithm is formulated to provide real time implementation. Our procedure is generally applicable to detect locally periodic components in signals s which can be modeled as s(t) equals A(t)F(h(t)) + N(t) for t in I, where F is a periodic signal, A is a non-negative slowly varying function, and h is strictly increasing with h' slowly varying, N denotes background activity. For example, the method can be applied in the context of epileptic seizure detection. In this case, we try to detect seizure periodics in EEG and ECoG data. In the case of ECoG data, N is essentially 1/f noise. In the case of EEG data and for t in I,N includes noise due to cranial geometry and densities. In both cases N also includes standard low frequency rhythms. Periodicity detection has other applications including ocean wave prediction, cockpit motion sickness prediction, and minefield detection.

    Imbalance in shoulder rotator muscles is a well-documented problem in swimmers, and it is important to implement land-based strength training programs. Meanwhile, the effects of a detraining period on swimmers' shoulder rotator muscles are unknown. The purpose of this study was to analyze the effects of a strength training program and detraining on the strength and balance of shoulder rotator cuff muscles in young swimmers, despite the continuity of usual water training. An experimental group (n = 20) and a control group (n = 20) of young male swimmers with the same characteristics (age, body mass, height, training volume, and maturational state) were evaluated. In both groups, the peak torques of shoulder internal (IR) and external (ER) rotators were assessed during preseason, midseason (16 weeks), and postseason (32 weeks). The experimental group underwent a strength training regimen from baseline to 16 weeks and a detraining period from 16 to 32 weeks. Concentric action at 60°·s-1 and 180°·s-1 was measured using an isokinetic dynamometer. The ER/IR strength ratios were obtained. At 60°·s-1, there were significant increments in IR strength and the ER/IR ratio in both shoulders. This trend was the same throughout the competitive season. The tendency was the same at 180°·s-1 because training effects were noted primarily in IR and ER/IR ratios. Moreover, the absence of land-based strength training, from 16 to 32 weeks, revealed a reduction in the ER/IR ratio values in both shoulders. Our findings suggest that young swimmers' coaches should use dry-land strength training protocols, and that it is recommended that these should be conducted on a regular basis (during the whole season).

    Background Vardenafil (Levitra®) represents a potent and highly selective phosphodiesterase type 5 (PDE5) inhibitor, which is established for treatment of various diseases. There are several unpublished reports from patients stating that vardenafil has a considerable therapeutic effect on their concomitant tinnitus. This pilot study was conducted to specifically assess the effect of vardenafil in patients with chronic tinnitus. Methods This trial was based on a prospective, randomized, double-blind, placebo-controlled, parallel group design. Fourty-two consecutive subjects with mon- or binaural chronic tinnitus received 10 mg vardenafil (N = 21) or matching placebo tablets (N = 21) administered orally twice a day over a period of 12 weeks. Clinical examination and data acquisition took place at each visit: at baseline, after 4 weeks, after 12 weeks (end of treatment with study medication), and at non-medicated follow-up after 16 weeks. Assessment of clinical effectiveness was based on a standardized tinnitus questionnaire (TQ), the Short Form 36 health survey (SF-36), audiometric measurements (mode, pitch and loudness of tinnitus; auditory thresholds) and biomarkers of oxidative stress in patients' blood (malondialdehyde, protein carbonyl, homocysteine and total antioxidative status). Therapeutic efficacy was evaluated by comparison of subjective and objective parameters with baseline data between both treatment groups (ANCOVA). Results Vardenafil had no superior efficacy over placebo in the treatment of chronic tinnitus during this study. The primary efficacy criterion 'TQ total score' failed to demonstrate significant improvement compared to placebo. Subjective reports of TQ subscales and general quality of life areas (SF-36), objective audiometric examinations as well as investigated biomarkers for oxidative stress did not reveal any significant treatment effects. The safety profile was favorable and consistent with that in other vardenafil studies. Conclusion

    This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP) is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly. PMID:21966655

  18. [Periodic abstinence: its possibilities].

    PubMed

    1981-05-01

    Experience with family planning mehods requiring periodic sexual abstinence has been varied. During the last decade interest has centered on 2 methods, the cervical mucus and the sympto-thermal, which are based on identifying the onset of the fertile period. During the 1970s, the Australian physicians John and Evelyn Billings developed the cervical mucus method, in which changes in the quanitity and characteristics of cervical mucus are used to determine the moment of ovulation. The sympto-thermal method depends on identification of the slight rise in basal body temperature that occurs in the latter part of the menstrual cycle as well as cervical mucus changes and sometimes the calendar to determine the fertile period. The Catholic Church has been the main proponent of periodic abstinence methods, but since 1973 the World Health Organization has invested US$3.3 million on research in such methods. The Billings method requires differentiating between dry, wet, and very wet mucus in the vagina and between different consistencies of mucus. The method ususally requires 1-3 months for instruction and sexual abstinence is usually recommended for the 1st month. The average number of days of required abstinence was 9 in a study of 66 women and 15-18 in a study of 870 women. Many women with short menstrual cycles do not experience postmenstrual dry days, in which case abstinence may be required as many as 13 days out of 23. 18.8% of users of periodic abstinence methods in 1 North American study became pregnant in the 1st year, but most were using the calendar method. Women who desired to terminate childbearing had only about 1/2 as many failures with periodic abstinence methods as did women wishing to postpone a birth. PMID:12311397

    Periodically kicked turbulence is theoretically analyzed within a mean-field theory. For large enough kicking strength A and kicking frequency f the Reynolds number grows exponentially and then runs into some saturation. The saturation level Re(sat) can be calculated analytically; different regimes can be observed. For large enough Re we find Re(sat) approximately Af, but intermittency can modify this scaling law. We suggest an experimental realization of periodically kicked turbulence to study the different regimes we theoretically predict and thus to better understand the effect of forcing on fully developed turbulence.

    2003-08-01

    This study attempts: (1) to verify that serum antimuscarinic activity is related to clozapine dose, and more importantly to clozapine plasma concentrations; (2) to explore whether norclozapine has serum antimuscarinic activity; (3) to explore whether antimuscarinic activity is related to clozapine side effects; and (4) to compare the serum antimuscarinic activities of clozapine with those of antiparkinsonian drugs and other antipsychotics. In 39 patients participating in a double-blind clozapine study, the [3H]QNB assay was used to measure serum antimuscarinic activity: (1) on baseline medications; (2) after a 4-week haloperidol trial; (3) after a 16-week clozapine trial of either 100, 300, or 600 mg/d; and (4) after 1 or 2 consecutive 16-week clozapine trials with remaining doses in nonresponders. Clozapine levels predicted serum antimuscarinic activity better than clozapine dose. At the end of the 1st clozapine trial, the correlation with the levels explained 69% of the variance of serum antimuscarinic activity (r = 0.83, P < 0.001, N = 34). Clozapine levels were good predictors of serum antimuscarinic activity only in patients taking 300 or 600 mg/d. After correcting for clozapine levels, the within-subject correlation between norclozapine levels and serum antimuscarinic activity was relatively high and significant (r = 0.54, F = 26.7, df = 1.65, P < 0.001). Constipation was significantly associated with higher serum antimuscarinic activity during the 1st clozapine trial. Clozapine was associated with clearly higher antimuscarinic activity than other antipsychotics or low doses of antiparkinsonians. In vitro studies and new clinical studies are needed to verify whether norclozapine may significantly contribute to antimuscarinic activity during clozapine treatment. PMID:12920408

  7. Astrophysical implications of periodicity

    Muller, Richard A.

    1988-01-01

    Two remarkable discoveries of the last decade have profound implications for astrophysics and for geophysics. These are the discovery by Alvarez et al., that certain mass extinctions are caused by the impact on the earth of a large asteroid or comet, and the discovery by Raup and Sepkoski that such extinctions are periodic, with a cycle time of 26 to 30 million years. The validity of both of these discoveries is assumed and the implications are examined. Most of the phenomena described depend not on periodicity, but just on the weaker assumption that the impacts on the earth take place primarily in showers. Proposed explanations for the periodicity include galactic oscillations, the Planet X model, and the possibility of Nemesis, a solar companion star. These hypotheses are critically examined. Results of the search for the solar companion are reported. The Deccan flood basalts of India have been proposed as the impact site for the Cretaceous impact, but this hypotheisis is in contradiction with the conclusion of Courtillot et al., that the magma flow began during a period of normal magnetic field. A possible resolution of this contradiction is proposed.

  12. Oscillations following periodic reinforcement.

    Three experiments examined behavior in extinction following periodic reinforcement. During the first phase of Experiment 1, four groups of pigeons were exposed to fixed interval (FI 16s or FI 48s) or variable interval (VI 16s or VI 48s) reinforcement schedules. Next, during the second phase, each session started with reinforcement trials and ended with an extinction segment. Experiment 2 was similar except that the extinction segment was considerably longer. Experiment 3 replaced the FI schedules with a peak procedure, with FI trials interspersed with non-food peak interval (PI) trials that were four times longer. One group of pigeons was exposed to FI 20s PI 80s trials, and another to FI 40s PI 160s trials. Results showed that, during the extinction segment, most pigeons trained with FI schedules, but not with VI schedules, displayed pause-peck oscillations with a period close to, but slightly greater than the FI parameter. These oscillations did not start immediately after the onset of extinction. Comparing the oscillations from Experiments 1 and 2 suggested that the alternation of reconditioning and re-extinction increases the reliability and earlier onset of the oscillations. In Experiment 3 the pigeons exhibited well-defined pause-peck cycles since the onset of extinction. These cycles had periods close to twice the value of the FI and lasted for long intervals of time. We discuss some hypotheses concerning the processes underlying behavioral oscillations following periodic reinforcement. PMID:18992793

    Purpose: To evaluate the intra-fractional prostate movement range during the beam delivery and implement new IGRT method to correct the prostate movement during the hypofractionated prostate treatment delivery. Methods: To evaluate the prostate internal motion range during the beam delivery, 11 conventional treatments were utilized. Two-arc RapidArc plans were used for the treatment delivery. Orthogonal KV imaging is performed in the middle of the treatment to correct intra-fractional prostate movement. However, it takes gantry-mounted on-board imaging system relative long time to finish the orthogonal KV imaging because of gantry rotation. To avoid gantry movement and accelerate the IGRT processing time, orthogonal KV-MV image pair is tested using the OBI daily QA Cube phantom. Results: The average prostate movement between two orthogonal KV image pairs was 0.38cm (0.20cm ∼ 0.85cm). And the interval time between them was 6.71 min (4.64min ∼ 9.22 min). 2-arc beam delivery time is within 3 minutes for conventional RapidArc treatment delivery. Hypofractionated treatment or SBRT need 4 partial arc and possible non-coplanar technology, which need much longer beam delivery time. Therefore prostate movement might be larger. New orthogonal KV-MV image pair is a new method to correct the prostate movement in the middle of the beam delivery if real time tracking method is not available. Orthogonal KV-MV image pair doesn’t need gantry rotation. Images were acquired quickly which minimized possible new prostate movement. Therefore orthogonal KV-MV image pair is feasible for IGRT. Conclusion: Hypofractionated prostate treatment with less PTV margin always needs longer beam delivery time. Therefore prostate movement correction during the treatment delivery is critical. Orthogonal KV-MV imaging pair is efficient and accurate to correct the prostate movement during treatment beam delivery. Due to limited fraction number and high dose per fraction, the MV imaging dose is

    Purpose: To retrospectively review our experience with whole abdominopelvic radiotherapy (WAPRT) using intensity-modulated arc therapy in the palliative treatment of chemotherapy-resistant ovarian cancer with bulky peritoneal disease. Methods and Materials: Between April 2002 and April 2008, 13 patients were treated with WAPRT using intensity-modulated arc therapy. We prescribed a dose of 33 Gy to be delivered in 22 fractions of 1.5 Gy to the abdomen and pelvis. All patients had International Federation of Gynecology and Obstetrics Stage III or IV ovarian cancer at the initial diagnosis. At referral, the median age was 61 years, and the patients had been heavily pretreated with surgery and chemotherapy. All patients had symptoms from their disease, including gastrointestinal obstruction or subobstruction in 6, minor gastrointestinal symptoms in 2, pain in 4, ascites in 1, and vaginal bleeding in 2. A complete symptom or biochemical response required complete resolution of the patient's symptoms or cancer antigen-125 level. A partial response required {>=}50% resolution of these parameters. The actuarial survival was calculated from the start of radiotherapy. Results: The median overall survival was 21 weeks, with a 6-month overall survival rate of 45%. The 9 patients who completed treatment obtained a complete symptom response, except for ascites (partial response). The median and mean response duration (all symptoms grouped) was 24 and 37 weeks, respectively. Of the 6 patients presenting with obstruction or subobstruction, 4 obtained a complete symptom response (median duration, 16 weeks). Conclusion: WAPRT delivered using intensity-modulated arc therapy offers important palliation in the case of peritoneal metastatic ovarian cancer. WAPRT resolved intestinal obstruction for a substantial period.

    Over the last 10 years, accumulated experimental and clinical evidence has supported the idea that AT1 receptor subtype is involved in epilepsy. Recently, we have shown that the selective AT1 receptor antagonist losartan attenuates epileptogenesis and exerts neuroprotection in the CA1 area of the hippocampus in epileptic Wistar rats. This study aimed to verify the efficacy of long-term treatment with losartan (10 mg/kg) after kainate-induced status epilepticus (SE) on seizure activity, behavioral and biochemical changes, and neuronal damage in a model of co-morbid hypertension and epilepsy. Spontaneous seizures were video- and EEG-monitored in spontaneously hypertensive rats (SHRs) for a 16-week period after SE. The behavior was analyzed by open field, elevated plus maze, sugar preference test, and forced swim test. The levels of serotonin in the hippocampus and neuronal loss were estimated by HPLC and hematoxylin and eosin staining, respectively. The AT1 receptor antagonism delayed the onset of seizures and alleviated their frequency and duration during and after discontinuation of treatment. Losartan showed neuroprotection mostly in the CA3 area of the hippocampus and the septo-temporal hilus of the dentate gyrus in SHRs. However, the AT1 receptor antagonist did not exert a substantial influence on concomitant with epilepsy behavioral changes and decreased 5-HT levels in the hippocampus. Our results suggest that the antihypertensive therapy with an AT1 receptor blocker might be effective against seizure activity and neuronal damage in a co-morbid hypertension and epilepsy.

    We show that an amoeboid organism can anticipate the timing of periodic events. The plasmodium of the true slime mold Physarum polycephalum moves rapidly under favourable conditions, but stops moving when transferred to less-favourable conditions. Plasmodia exposed to unfavourable conditions, presented in three consecutive pulses at constant intervals, reduced their locomotive speed in response to each episode. When subsequently subjected to favourable conditions, the plasmodia spontaneously reduced their locomotive speed at the time point when the next unfavourable episode would have occurred. This implied anticipation of impending environmental change. After this behaviour had been evoked several times, the locomotion of the plasmodia returned to normal; however, the anticipatory response could subsequently be induced by a single unfavourable pulse, implying recall of the memorized periodicity. We explored the mechanisms underlying these behaviours from a dynamical systems perspective. Our results hint at the cellular origins of primitive intelligence and imply that simple dynamics might be sufficient to explain its emergence.

  18. Periodic minimal surfaces

    1985-04-01

    A minimal surface is one for which, like a soap film with the same pressure on each side, the mean curvature is zero and, thus, is one where the two principal curvatures are equal and opposite at every point. For every closed circuit in the surface, the area is a minimum. Schwarz1 and Neovius2 showed that elements of such surfaces could be put together to give surfaces periodic in three dimensions. These periodic minimal surfaces are geometrical invariants, as are the regular polyhedra, but the former are curved. Minimal surfaces are appropriate for the description of various structures where internal surfaces are prominent and seek to adopt a minimum area or a zero mean curvature subject to their topology; thus they merit more complete numerical characterization. There seem to be at least 18 such surfaces3, with various symmetries and topologies, related to the crystallographic space groups. Recently, glyceryl mono-oleate (GMO) was shown by Longley and McIntosh4 to take the shape of the F-surface. The structure postulated is shown here to be in good agreement with an analysis of the fundamental geometry of periodic minimal surfaces.

  19. Update on the treatment of genital warts.

    This review summarizes new treatments from the last seven years employed for the treatment of genital warts caused by human papillomavirus (HPV). Imquimod 3.75% is a new agent with fewer side effects and perhaps a better dosing schedule than imquimod 5%, but is not more effective. Sinecatechins/Polyphenon E 15%, a novel extract from green tea can be effective against genital warts but requires three times a day dosing and is not more effective than existing treatments; the treatment course is 12-16 weeks. Photodynamic therapy combined with other destructive modalities might increase the cure rate for genital warts. The quadrivalent vaccine against HPV 6, 11, 16, 18 is decreasing the incidence of warts in the western world but the evidence does not support vaccination as a treatment for those already infected by HPV. Hyperthermia and immunomodulators might be positive additions to the armamentarium of clinicians. In sum, there are new tools that physicians can use but none is really a great advance over what was available a decade ago. PMID:24011309

    Reorienting of voluntary attention enables the processing of stimuli at previously unattended locations. Although studies have identified a ventral fronto-parietal network underlying attention [1, 2], little is known about whether and how early visual areas are involved in involuntary [3, 4] and even less in voluntary [5] reorienting, and their temporal dynamics are unknown. We used transcranial magnetic stimulation (TMS) over the occipital cortex to interfere with attentional reorienting and study its role and temporal dynamics in this process. Human observers performed an orientation discrimination task, with either valid or invalid attention cueing, across a range of stimulus contrasts. Valid cueing induced a behavioral response gain increase, higher asymptotic performance for attended than unattended locations. During subsequent TMS sessions, observers performed the same task, with high stimulus contrast. Based on phosphene mapping, TMS double pulses were applied at one of various delays to a consistent brain location in retinotopic areas (V1/V2), corresponding to the evoked signal of the target or distractor, in a valid or invalid trial. Thus, the stimulation was identical for the four experimental conditions (valid/invalid cue condition × target/distractor-stimulated). TMS modulation of the target and distractor were both periodic (5 Hz, theta) and out of phase with respect to each other in invalid trials only, when attention had to be disengaged from the distractor and reoriented to the target location. Reorientation of voluntary attention periodically involves V1/V2 at the theta frequency. These results suggest that TMS probes theta phase-reset by attentional reorienting and help link periodic sampling in time and attention reorienting in space. PMID:27265395

    Geyser eruption frequency is not constant over time and has been shown to vary with small (???10-6) strains induced by seismic events, atmospheric loading, and Earth tides. The geyser system is approximated as a permeable conduit of intensely fractured rock surrounded by a less permeable rock matrix. Numerical simulation of this conceptual model yields a set of parameters that controls geyser existence and periodicity. Much of the responsiveness to remote seismicity and other small strains in the Earth can be explained in terms of variations in permeability and lateral recharge rates.

    The authors estimate the degree of oxidation of the thiol group in dextran with various mol. wt. and make an attempt at a kinetic description of the main parameters of the process. Polyglucin was used. The results are shown of experiments done on the estimation of the amount of products formed in the process of oxidation of polyglucin in which the reaction stopped as a result of complete exhaustion of one of the original reagents. To estimate the reactivity of the thiol group toward oxidation, the authors studied the interaction of potassium periodate with alpha-D-glucose, isolated by the monomer unit of dextran.

    In the past few years, researchers have uncovered evidence that several kinds of geological and biological events seem to show regular cycles of similar lengths. For example, Rohde and Muller [2005] looked at the record of diversity of marine organisms over the past 540 million years and found evidence for two cycles in the data—a roughly 62-million-year cycle and a longer cycle of about 140 million years. This was followed by reports of an approximately 56-million-year cycle in long-term stratigraphic sequences in sedimentary basins [Meyers and Peters, 2011] and a 59-million-year period in the marine strontium-isotope record [Melott et al., 2012]. A similar period may even exist in atmospheric carbon dioxide over the past 542 million years of the Phanerozoic [Franks et al., 2012]. A cycle of about 140 million years was reported by Veizer et al. [2000] and Mayhew et al. [2008] in long-term fluctuations in global climate.

    Breast feeding provides a lot of short and long-term benefits for the mother and the baby. It prevents the baby of gastrointestinal, urinary and respiratory infections, atopical conditions and assures long-term protection of cardiovascular and metabolic diseases. The breast feeding decreases the risk for the mother of ovary and breast carcinoma and creates a positive emotional bond between the mother and the baby Mother's milk is a species specific; its content is relatively stable regardless of mother's age race, way and place of living. Mother's milk is not sterile. There is a 10 year international trial held in Spanish and Finnish universities. It has identified and count all microorganisms in mother's milk (more than 700) and proved that their content and quantity varies according the age of the baby. Mother's milk is a source of lactobacillus for baby's intestines and most of them have probiotic potential. Lactobacillus fermentum Lc40 (hereditum) is isolated from mother's milk. It has a good viability in gastrointestinal system, high level of adhesion to intestinal epithelium cells, produces glutation--strong antioxidant, good antibacterial activity to entero-pathogens and potential of increasing the immunologic response. Clinical trials reveal that Lactobacillus fermentum plays important role to microflora balance of mother's milk in mastitis during lactation. Many trials estimating the efficiency of lactobacillus fermentum in prevention and treatment of acute and subacute mastitis have been carried out. The results of them open a new door in front of us in the treatment of these conditions--treatment with probiotics instead of antibiotics. PMID:27514147

    We show the existence of periodic exploding dissipative solitons. These non-chaotic explosions appear when higher-order nonlinear and dispersive effects are added to the complex cubic-quintic Ginzburg-Landau equation modelling soliton transmission lines. This counterintuitive phenomenon is the result of period-halving bifurcations leading to order (periodic explosions), followed by period-doubling bifurcations (or intermittency) leading to chaos (non-periodic explosions).

    Space flight-induced muscle atrophy, particularly in the postural and locomotorymuscles, may impair task performance during long-duration space missions and planetary exploration. High intensity free weight (FW) resistive exercise training has been shown to prevent atrophy during bed rest, a space flight analog. NASA developed the Advanced Resistive Exercise Device (ARED) to simulate the characteristics of FW exercise (i.e. constant mass, inertial force) and to be used as a countermeasure during International Space Station (ISS) missions. PURPOSE: To compare the efficacy of ARED and FW training to induce hypertrophy in specific muscle groups in ambulatory subjects prior to deploying ARED on the ISS. METHODS: Twenty untrained subjects were assigned to either the ARED (8 males, 3 females) or FW (6 males, 3 females) group and participated in a periodizedtraining protocol consisting of squat (SQ), heel raise (HR), and deadlift(DL) exercises 3 d wk-1 for 16 wks. SQ, HR, and DL muscle strength (1RM) was measured before, after 8 wks, and after 16 wks of training to prescribe exercise and measure strength changes. Muscle volume of the vastigroup (V), hamstring group (H), hip adductor group (ADD), medial gastrocnemius(MG), lateral gastrocnemius(LG), and deep posterior muscles including soleus(DP) was measured using MRI pre-and post-training. Consecutive cross-sectional images (8 mm slices with a 2 mm gap) were analyzed and summed. Anatomical references insured that the same muscle sections were analyzed pre-and post-training. Two-way repeated measures ANOVAs (p<0.05) were used to test for differences in muscle strength and volume between training devices. RESULTS: SQ, HR, and DL 1RM increased in both FW (SQ: 49+/-6%, HR: 12+/-2%, DL: 23+/-4%) and ARED (SQ: 31+/-4%, HR: 18+/-2%, DL: 23+/-3%) groups. Both groups increased muscle volume in the V (FW: 13+/-2%, ARED: 10+/-2%), H (FW: 3+/-1%, ARED: 3+/-1 %), ADD (FW: 15=/-2%, ARED: 10+/-1%), LG (FW: 7+/-2%, ARED: 4+/-1%), MG (FW: 7+/-2%, ARED: 5+/-2%), and DP (FW: 2+/-1%; ARED: 2+/-1%) after training. There were no between group differences in muscle strength or volume. CONCLUSIONS: The increase in muscle volume and strength following ARED training is not different than FW training. With the training effects similar to FW and a 600 lb load capacity, ARED likely will protect against muscle atrophy in microgravity.

    The effect of 2004 Kawasaki disease (KD) guidelines on diagnosis and outcome of KD is lacking. We studied the epidemiology of KD in our region and compared the incidence, presentation, and outcome of KD before and after publication of the guidelines. A retrospective chart review was conducted for patients admitted with a diagnosis of KD. Demographics, laboratory data, and clinical data were collected. Comparison was made between 2 groups: prepublication (2000-2004) and postpublication (2005-2009) of guidelines. A total of 312 children were included; 64% were African American, 23% White, and 2% Asian; 61% were boys; 79% were complete KD, and 66% were in winter/spring. There was a significant increase in KD cases over the 11 years. There was no significant difference in clinical findings and outcome between the 2 groups. KD admissions in our region significantly increased during the postpublication period. There was no difference in clinical presentation, laboratory findings, or outcome between the 2 groups.

    Exposure to combat frequently imparts a sense of aloneness, guilt, and helplessness. These and other intrapsychic and interpersonal issues need to be addressed in treating Vietnam veterans suffering from posttraumatic stress disorder (PTSD). Group therapy is proposed as a core treatment modality for dealing with these problems. A model is proposed in which patients are treated for 1 year or more in weekly groups that meet for 16-week sequential segments. Clinical guidelines are made explicit to new members by the co-therapists. Discussion topics deal not only with traumatic experiences related to combat, but also with important pre- and postwar issues that are relevant to the symptoms of PTSD. Timely integration and working through of these issues in the group is critical. PMID:1572783

    The periodically oscillating plasma sphere, or POPS, is a novel fusion concept first proposed by D. C. Barnes and R. A. Nebel [Fusion Technol. 38, 28 (1998)]. POPS utilizes the self-similar collapse of an oscillating ion cloud in a spherical harmonic oscillator potential well formed by electron injection. Once the ions have been phase-locked, their coherent motion simultaneously produces very high densities and temperatures during the collapse phase of the oscillation. A requirement for POPS is that the electron injection produces a stable harmonic oscillator potential. This has been demonstrated in a gridded inertial electrostatic confinement device and verified by particle simulation. Also, the POPS oscillation has been confirmed experimentally through observation that the ions in the potential well exhibit resonance behavior when driven at the POPS frequency. Excellent agreement between the observed POPS frequencies and the theoretical predictions has been observed for a wide range of potential well depths and three different ion species. Practical applications of POPS require large plasma compressions. These large compressions have been observed in particle simulations, although space charge neutralization remains a major issue.

  15. An appraisal of golimumab in the treatment of severe, active nonradiographic axial spondyloarthritis

    2016-01-01

    Golimumab (Simponi®) is a fully human tumor necrosis factor α inhibitor (TNFi) antibody administered subcutaneously. In the European Union, golimumab is indicated for the treatment of adults with severe, active axial spondyloarthritis (axSpA), which includes both ankylosing spondylitis (AS) and nonradiographic axSpA (nr-axSpA). In the US, it is indicated for the treatment of adults with active AS only. This article reviews the efficacy and tolerability of golimumab in nr-axSpA patients compared to other TNFi agents (adalimumab, infliximab, etanercept, and certolizumab pegol). In one ongoing, well-designed controlled study (GO-AHEAD), data at 16 weeks showed that treatment with golimumab (50 mg every 4 weeks) was effective in improving the clinical signs and symptoms of disease in nr-axSpA patients. In addition, 16 weeks of treatment with golimumab reduced inflammation in the sacroiliac joints and spine in patients with nr-axSpA. Moreover, objective evidence of active inflammation at baseline, such as a positive magnetic resonance imaging scan and/or an elevated CRP level, was a good predictor of treatment response to golimumab. Golimumab was generally well tolerated in this study, with a tolerability profile consistent with that seen in previous clinical trials for other indications. Although additional long-term data are needed, current evidence indicates that golimumab is an effective option for the treatment of nr-axSpA. However, in the absence of comparative head-to-head trials, there is no recommended hierarchy for the first prescription of a TNFi agent for the treatment of either nr-axSpA or AS. PMID:27468228

    The in vivo bone response of 3D periodic hydroxyapatite (HA) scaffolds is investigated. Two groups of HA scaffolds (11 mm diameter x 3.5 mm thick) are fabricated by direct-write assembly of a concentrated HA ink. The scaffolds consist of cylindrical rods periodically arranged into four quadrants with varying separation distances between rods. In the first group, HA rods (250 microm in diameter) are patterned to create pore channels, whose areal dimensions are 250 x 250 microm(2) in quadrant 1, 250 x 500 microm(2) in quadrants 2 and 4, and 500 x 500 microm(2) in quadrant 3. In the second group, HA rods (400 microm in diameter) are patterned to create pore channels, whose areal dimensions of 500 x 500 microm(2) in quadrant 1, 500 x 750 microm(2) in quadrants 2 and 4, and 750 x 750 microm(2) in quadrant 3. Each group of scaffolds is partially densified by sintering at 1200 degrees C prior to being implanted bilaterally in trephine defects of skeletally mature New Zealand White rabbits. Their tissue response is evaluated at 8 and 16 weeks using micro-computed tomography, histology, and scanning electron microscopy. New trabecular bone is conducted rapidly and efficiently across substantial distances within these patterned 3D HA scaffolds. Our observations suggest that HA rods are first coated with a layer of new bone followed by subsequent scaffold infilling via outward and inward radial growth of the coated regions. Direct-write assembly of 3D periodic scaffolds composed of micro-porous HA rods arrayed to produce macro-pores that are size-matched to trabecular bone may represent an optimal strategy for bone repair and replacement structures.

    Children with ASD show high frequency of restricted and repetitive behaviors (RRBs); however, higher-order RRBs, such as restricted interests, have remained largely resistant to treatment. This study evaluated change in severity of RRBs following a 16-weeks open trial of Pivotal Response Treatment (PRT). Participants included 15 children with ASD ages 4-7 years. RRBs, as measured by the repetitive behavioral scales-revised (RBS-R) and aberrant behaviors checklist, decreased significantly after treatment. These reductions remained significant after controlling for change in social communication skills. PRT shows promise in reducing RRBs; although PRT explicitly addresses pivotal social communication skills, there is a secondary and less direct effect on RRBs. PMID:27230762

    Results are presented of a detailed period study of the eclipsing binary system SZ Arietis, based on up-to-date collection of minima. A new period (P = 1.7175405 d) of the SZ Ari was found, and the period changes (with the new period) in different portions of the O-C diagram were estimated. The average period change (leaving out an unusual value) was estimated to be about 0.00006 d. The O-C diagram displayed a sinusoidal variation, indicating that the SZ Ari system may be a three-body system, having a period of nearly 66 years.

    Background Ethyl glucuronide (EtG) is an alcohol biomarker with potential utility as a clinical research and alcohol treatment outcome. Debate exists regarding the appropriate cutoff level for determining alcohol use, particularly with the EtG immunoassay. This study determined the EtG immunoassay cutoff levels that most closely correspond to self-reported drinking in alcohol dependent outpatients. Methods Eighty adults with alcohol dependence and mental illness, taking part in an alcohol treatment study, provided urine samples three times per week for up to 16-weeks (1589 samples). Self-reported drinking during 120 hours prior to each sample collection was assessed. Receiver Operating Characteristic analyses were conducted to assess the ability of the EtG immunoassay to detect self-reported alcohol use across 24–120 hour time periods. Sensitivity and specificity of EtG immunoassay cutoff levels was compared in 100 ng/mL increments (100 ng/mL–500 ng/mL) across 24–120 hours. Results Over half (57%) of the 1589 samples indicated recent alcohol consumption. The EtG immunoassay closely corresponded to self-reported drinking from 24 (AUC=0.90, 95% CI:0.88, 0.92) to 120 hours (AUC=0.88, 95% CI:0.87, 0.90). When cutoff levels were compared across 24–120 hours, 100 ng/mL had the highest sensitivity (0.93–0.78) and lowest specificity (0.67–0.85). Relative to 100 ng/mL, the 200 ng/mL cutoff demonstrated a reduction in sensitivity (0.89–0.67), but improved specificity (0.78–0.94). The 300 ng/mL, 400 ng/mL, and 500 ng/mL cutoffs demonstrated the lowest sensitivity (0.86 to 0.33) and highest specificity (0.86–0.97) over 24 to 120 hours. Conclusions For detecting alcohol use for greater than 24 hours, the 200 ng/mL cutoff level is recommended for use as a research and clinical outcome. PMID:25866234

    Objectives There are very little data on pre-excitation syndrome (PS) in the elderly. We investigated the influence of advancing age on clinical presentation, treatment and long-term outcome of PS. Setting Single-centre retrospective study of patient files. Participants In all, 961 patients (72 patients ≥60 years (mean 68.5±6), 889 patients <60 years (mean 30.5±14)) referred for overt pre-excitation and indication for electrophysiological study (EPS) were followed for 5.3±5 years. Usual care included 24 h Holter monitoring, echocardiography and EPS. Patients underwent accessory pathway (AP) ablation if necessary. Primary and secondary outcome measures Occurrence of atrial fibrillation (AF) or procedure-induced adverse event. Results Electrophysiological data and recourse to AP ablation (43% vs 48.5%, p=0.375) did not significantly differ between the groups. Older patients more often had symptomatic forms (81% vs 63%, p=0.003), history of spontaneous AF (8% vs 3%, p=0.01) or adverse presentation (poorly tolerated arrhythmias: 18% vs 7%, p=0.0009). In multivariable analysis, patients ≥60 years had a significantly higher risk of history of AF (OR=4.2, 2.1 to 8.3, p=0.001) and poorly tolerated arrhythmias (OR=3.8, 1.8 to 8.1, p=0.001). Age ≥60 years was associated with an increased major AP ablation complication risk (10% vs 1.9%, p=0.006). During follow-up, occurrence of AF (13.9% vs 3.6%, p<0.001) and incidence of poorly tolerated tachycardia (4.2% vs 0.6%, p=0.001) were more frequent in patients ≥60 years, although frequency of ablation failure or recurrence was similar (20% vs 15.5%, p=0.52). In multivariable analysis, patients ≥60 years had a significantly higher risk of AF (OR=2.9, 1.2 to 6.8, p≤0.01). Conclusions In this retrospective monocentre study, patients ≥60 years referred for PS work up appeared at higher risk of AF and adverse presentation, both prior and after the work up. These results suggest that, in elderly

    The purpose of this study was to determine how three different measures of motivation (cognitive motivation, taking steps, and self-efficacy for change and maintenance) predict substance use outcomes after engaging in a Motivational Interviewing intervention. Participants were 225 high school students enrolled in Project Reducing the Effects of Alcohol and Drugs on Youth (Project READY), a NIDA-funded intervention initially developed with Motivational Interviewing (MI) principles for adolescents identified by schools as having problems with alcohol or other drug use. We measured motivation at multiple time points during the intervention in multiple methods. Cognitive motivation was assessed using a Decisional Balance matrix at Session 3 of treatment. We measured self-efficacy with the Situational Confidence Questionnaire, administered at 4-, 8-, 12-, and 16-week follow-ups. A measure of taking steps (SOCRATES, v. 8) was administered at intake and Session 8. We hypothesized that motivation would follow the Transtheoretical Model (TTM) pathway, and we proposed a model where cognitive motivation would predict self-confidence for change and taking steps toward change, and self-confidence and taking steps would predict substance use outcomes. We tested our model using path analysis in AMOS and found support for a motivational continuum predicting percent days abstinent at 16-week follow-up [χ(2) = 2.75, df = 7, p = .90, CFI = 1, RMSEA (90% confidence interval) = .00 - .03]. This model demonstrates that motivational metrics predict unique outcomes at different time points and serve as important components of intervention. PMID:24467198

    Periodic structures are well known in various branches of physics for their ability to provide a stopband. In this article, using optical periodic structures we showed that, when a second periodicity – very closed to the original periodicity is introduced, large number of states appears in the stopband corresponding to the first periodicity. In the limit where the two periods matches, we have a continuum of states, and the original stopband completely disappears. This intriguing phenomena is uncovered by noticing that, regardless of the proximities of the two periodicities, there is an array of spatial points where the dielectric functions corresponding to the two periodicities interfere destructively. These spatial points mimic photonic atoms by satisfying the standards equations of quantum harmonic oscillators, and exhibit lossless, atom-like dispersions. PMID:26853945

    Cholestasis results from impairment in the excretion of bile, which may be due to mechanical obstruction of bile flow or impairment of excretion of bile components into the bile canaliculus. When present, cholestasis warrants prompt diagnosis and treatment. The differential diagnosis of cholestasis beyond the neonatal period is broad and includes congenital and acquired etiologies. It is imperative that the clinician differentiates between intrahepatic and extrahepatic origin of cholestasis. Treatment may be supportive or curative and depends on the etiology. Recent literature shows that optimal nutritional and medical support also plays an integral role in the management of pediatric patients with chronic cholestasis. This review will provide a broad overview of the pathophysiology, diagnostic approach, and management of cholestasis beyond the neonatal and infancy periods. PMID:27066444

    Although the carbonic anhydrase inhibitors have been used in the treatment of the primary periodic paralyses (PPs), their efficacy has not been demonstrated in double-blind, placebo-controlled trials. Therefore, we tested the efficacy of dichlorphenamide (DCP; Daranide), a potent carbonic anhydrase inhibitor, in the treatment of episodic weakness in the primary PPs. We performed two multicenter, randomized, double-blind, placebo-controlled crossover trials, one involving 42 subjects with hypokalemic periodic paralysis (HypoPP) and the other involving 31 subjects with potassium-sensitive periodic paralysis (PSPP). In each trial, two 8-week treatment periods were separated by an active washout period of at least 9 weeks. The primary outcome variable in the HypoPP trial was the occurrence of an intolerable increase in attack severity or frequency (end point). The primary outcome variable in the PSPP trial was the number of attacks per week. In the HypoPP trial, there were 13 subjects who exhibited a preference (in terms of the end point) for either DCP or placebo, and 11 of these preferred DCP. In the PSPP trial, DCP significantly reduced attack rates relative to placebo. DCP also significantly reduced attack rates relative to placebo in the HypoPP subjects. We conclude that DCP is effective in the prevention of episodic weakness in both HypoPP and PSPP. PMID:10632100

    Objective To explore the efficacy and safety of fluticasone propionate, cream and ointment, applied twice weekly in addition to maintenance treatment with emollients, in reducing the risk of relapse of chronic recurrent atopic dermatitis. Design Randomised, double blind, parallel group study of 20 weeks' duration. Setting Dermatology outpatient clinics (6 countries, 39 centres). Participants Adult (aged 12-65) patients with moderate to severe atopic dermatitis who were experiencing a flare. Methods Participants applied fluticasone propionate (0.05% cream or 0.005% ointment; once or twice daily) regularly for four weeks to stabilise their condition. The patients whose disease was brought under control then continued into a 16 week maintenance phase, applying emollient on a daily basis with a bath oil as needed and either the same formulation of fluticasone propionate or its placebo base (emollient alone) twice weekly to the areas that were usually affected. Main outcome measure Time to relapse of atopic dermatitis during maintenance phase. Results 376 patients entered the stabilisation phase, and 295 continued into the maintenance phase. After 16 weeks in the maintenance phase, the disease remained under control in 133 patients (87 using fluticasone propionate twice weekly, 46 using emollient alone), 135 (40 fluticasone propionate, 95 emollient) had experienced a relapse, and 27 had discontinued. Median time to relapse was six weeks for emollient alone compared with more than 16 weeks for additional fluticasone propionate. Patients who applied fluticasone propionate cream twice weekly were 5.8 times less likely (95% confidence interval 3.1 to 10.8, P < 0.001) and patients using fluticasone propionate ointment 1.9 times less likely (1.2 to 3.2, P=0.010) to have a relapse than patients applying emollient alone. The groups showed no differences in adverse events. Conclusion After atopic dermatitis had been stabilised the addition of fluticasone propionate twice weekly

    In the molecular target treatment strategy of metastatic colorectal cancer patients panitumumab represents a new class of drugs due to its fully human nature, and no need for premedication and loading dose. Panitumumab binds to epidermal growth factor receptor (EGFR) selectively. In registration pivotal studies the analysis of patient subgroups for KRAS status gives strong evidence for the important role of RAS oncogene: median progression-free survival was 16 weeks on panitumumab arm in KRAS wild-type patients (8 weeks in best supportive care), while in KRAS mutant patients panitumumab showed no efficacy, however adverse events were more frequent and severe. According to SmPC, panitumumab is indicated as monotherapy for the treatment of patients with EGFR expressing metastatic colorectal carcinoma with non-mutated (wild-type) KRAS after failure of fluoropyrimidine-, oxaliplatin- , and irinotecan-containing chemotherapy regimens. Adverse events are similar as with other EGFR inhibitors: skin symptoms (rash), lung infiltrates, diarrhoea, ion abnormalities of renal origin. The drug was formerly available via named patient reimbursement, and now is financed by diagnosis-related group (DRG) system. PMID:19581179

    We investigated the mechanisms by which Pivotal Response Treatment (PRT) improves social communication in a case series of 10 preschool-aged children with Autism Spectrum Disorder (ASD). Functional magnetic resonance imaging (fMRI) identified brain responses during a biological motion perception task conducted prior to and following 16 weeks of PRT treatment. Overall, the neural systems supporting social perception in these 10 children were malleable through implementation of PRT; following treatment, neural responses were more similar to those of typically developing children (TD). However, at baseline, half of the children exhibited hypoactivation, relative to a group of TD children, in the right posterior superior temporal sulcus (pSTS), and half exhibited hyperactivation in this region. Strikingly, the groups exhibited differential neural responses to treatment: The five children who exhibited hypoactivation at baseline evidenced increased activation in components of the reward system including the ventral striatum and putamen. The five children who exhibited hyperactivation at baseline evidenced decreased activation in subcortical regions critical for regulating the flow of stimulation and conveying signals of salience to the cortex—the thalamus, amygdala, and hippocampus. Our results support further investigation into the differential effects of particular treatment strategies relative to specific neural targets. Identification of treatment strategies that address the patterns of neural vulnerability unique to each patient is consistent with the priority of creating individually tailored interventions customized to the behavioral and neural characteristics of a given person.

The global asymptotical stability of positive periodic solutions is discussed further, and conditions for exponential convergence are given. The conditions we obtained are weaker than the previously known ones and can be easily reduced to several special cases.

    2014-01-01

    Objective: To study activin signaling and its blockade in sporadic inclusion body myositis (sIBM) through translational studies and a randomized controlled trial. Methods: We measured transforming growth factor β signaling by SMAD2/3 phosphorylation in muscle biopsies of 50 patients with neuromuscular disease (17 with sIBM). We tested inhibition of activin receptors IIA and IIB (ActRII) in 14 patients with sIBM using one dose of bimagrumab (n = 11) or placebo (n = 3). The primary outcome was the change in right thigh muscle volume by MRI at 8 weeks. Lean body mass, strength, and function were secondary outcomes. Twelve of the patients (10 bimagrumab, 2 placebo) participated in a subsequent 16-week observation phase. Results: Muscle SMAD2/3 phosphorylation was higher in sIBM than in other muscle diseases studied (p = 0.003). Eight weeks after dosing, the bimagrumab-treated patients increased thigh muscle volume (right leg +6.5% compared with placebo, p = 0.024; left leg +7.6%, p = 0.009) and lean body mass (+5.7% compared with placebo, p = 0.014). Subsequently, bimagrumab-treated patients had improved 6-minute walking distance, which peaked at 16 weeks (+14.6%, p = 0.008) compared with placebo. There were no serious adverse events; the main adverse events with bimagrumab were mild acne and transient involuntary muscle contractions. Conclusions: Transforming growth factor β superfamily signaling, at least through ActRII, is implicated in the pathophysiology of sIBM. Inhibition of ActRII increased muscle mass and function in this pilot trial, offering a potential novel treatment of sIBM. Classification of evidence: This study provides Class I evidence that for patients with inclusion body myositis, bimagrumab increases thigh muscle volume at 8 weeks. PMID:25381300

    2016-04-01

    We study the dynamics and the phase-space structures of Coulombic and self-gravitating versions of the classical one-dimensional three-body system with periodic boundary conditions. We demonstrate that such a three-body system may be reduced isomorphically to a spatially periodic system of a single particle experiencing a two-dimensional potential on a rhombic plane. For the case of both Coulombic and gravitational versions, exact expressions of the Hamiltonian have been derived in rhombic coordinates. We simulate the phase-space evolution through an event-driven algorithm that utilizes analytic solutions to the equations of motion. The simulation results show that the motion exhibits chaotic, quasiperiodic, and periodic behaviors in segmented regions of the phase space. While there is no evidence of global chaos in either the Coulombic or the gravitational system, the former exhibits a transition from a completely nonchaotic phase space at low energies to a mixed behavior. Gradual yet striking transitions from mild to intense chaos are indicated with changing energy, a behavior that differentiates the spatially periodic systems studied in this Rapid Communication from the well-understood free-boundary versions of the three-body problem. Our treatment of the three-body systems opens avenues for analysis of the dynamical properties exhibited by spatially periodic versions of various classes of systems studied in plasma and gravitational physics as well as in cosmology.

    For several years before equinox, the energetic charged and neutral particles in Saturn’s magnetosphere displayed strong periodicities near 10.8 hours, the same period observed in radio emissions and magnetic fields. These particle periodicities have now been observed at equinox in electrons, protons, oxygen ions, and neutral hydrogen and oxygen atoms at all energies greater than ~3 keV, the lowest energies measured by the Magnetospheric IMaging Instrument (MIMI) on the Cassini spacecraft. The equinoctial electrons exhibit a very strong period at 10.72 hours, while the protons have essentially no periodicity at all. Water group ions display a notable period at 10.73 hours. Both the electrons and the ions have curious overtones in their spectral structure that may be related to solar wind modulation. The energetic neutral hydrogen and oxygen atoms have strong periods of 10.79 hours at equinox. Within the uncertainties of the measurements, the ENA periods are slightly longer than the charged particle periods, although they cover a somewhat different time interval. For comparison, the Cassini magnetometer observed periodicities in Saturn’s magnetic field of 10.65 hours during the same equinoctial interval. These observations will be interpreted in terms of a wavy magnetodisk model.

    Many patients suffer from persistent angina due to coronary vasospasm despite optimal medical treatment. We treated a 46-year-old patient with severe and treatment-resistant coronary vasospasm with the endothelin-receptor antagonist bosentan. Using oxygen-15-labelled water in conjunction with oxygen 15-labelled carbon monoxide positron emission tomography (PET), we measured an impaired coronary flow reserve (CFR) in 6 out of 13 segments directly before the start of bosentan therapy. A repeated PET measurement after 16 weeks of bosentan revealed a completely normalized CFR in this patient. Furthermore, the patient reported less frequent and less severe chest pain. Our data suggest a potential role of endothelin-receptor antagonists for patients with severe coronary vasospasms. PMID:19593957

    The prevalence of onychomycosis, a superficial fungal infection that destroys the entire nail unit, is rising, with no satisfactory cure. The objective of this randomized, double-blind, placebo-controlled study was to examine the clinical efficacy and tolerability of 2% butenafine hydrochloride and 5% Melaleuca alternifolia oil incorporated in a cream to manage toenail onychomycosis in a cohort. Sixty outpatients (39 M, 21 F) aged 18-80 years (mean 29.6) with 6-36 months duration of disease were randomized to two groups (40 and 20), active and placebo. After 16 weeks, 80% of patients using medicated cream were cured, as opposed to none in the placebo group. Four patients in the active treatment group experienced subjective mild inflammation without discontinuing treatment. During follow-up, no relapse occurred in cured patients and no improvement was seen in medication-resistant and placebo participants. PMID:10357864

  3. On the Period-Amplitude and Amplitude-Period Relationships

    NASA Technical Reports Server (NTRS)

    Wilson, Robert M.; Hathaway, David H.

    2008-01-01

    Examined are Period-Amplitude and Amplitude-Period relationships based on the cyclic behavior of the 12-month moving averages of monthly mean sunspot numbers for cycles 0.23, both in terms of Fisher's exact tests for 2x2 contingency tables and linear regression analyses. Concerning the Period-Amplitude relationship (same cycle), because cycle 23's maximum amplitude is known to be 120.8, the inferred regressions (90-percent prediction intervals) suggest that its period will be 131 +/- 24 months (using all cycles) or 131 +/- 18 months (ignoring cycles 2 and 4, which have the extremes of period, 108 and 164 months, respectively). Because cycle 23 has already persisted for 142 months (May 1996 through February 2008), based on the latter prediction, it should end before September 2008. Concerning the Amplitude-Period relationship (following cycle maximum amplitude versus preceding cycle period), because cycle 23's period is known to be at least 142 months, the inferred regressions (90-percent prediction intervals) suggest that cycle 24's maximum amplitude will be about less than or equal to 96.1 +/- 55.0 (using all cycle pairs) or less than or equal to 91.0 +/- 36.7 (ignoring statistical outlier cycle pairs). Hence, cycle 24's maximum amplitude is expected to be less than 151, perhaps even less than 128, unless cycle pair 23/24 proves to be a statistical outlier.

It was observed as part of Variable Stars South's Cepheid project by Butterworth in 2014 and 2015 using DSLR photometry in BGR passbands and visually by Pearce in 2015. The known period changes are shown graphically and doubtful ones examined and discarded if necessary. With its period and amplitude with a frequently changing period it is a suitable and worthwhile object for visual observing.

    2011-02-01

    Purpose: To assess rate of disease progression from diagnosis to initiation of treatment for Stage I-IIIB non-small-cell lung cancer (NSCLC). Methods and Materials: Forty patients with NSCLC underwent at least two sets of computed tomography (CT) and 18-fluorodeoxyglucose positron emission tomography (PET) scans at various time intervals before treatment. Progression was defined as development of any new lymph node involvement, site of disease, or stage change. Results: Median time interval between first and second CT scans was 13.4 weeks, and between first and second PET scans was 9.0 weeks. Median initial primary maximum tumor dimension (MTD) was 3.5 cm (0.6-8.5 cm) with a median standardized uptake value (SUV) of 13.0 (1.7-38.5). The median MTD increased by a median of 1.0 cm (mean, 1.6 cm) between scans for a median relative MTD increase of 35% (mean, 59%). Nineteen patients (48%) progressed between scans. Rate of any progression was 13%, 31%, and 46% at 4, 8, and 16 weeks, respectively. Upstaging occurred in 3%, 13%, and 21% at these intervals. Distant metastasis became evident in 3%, 13%, and 13% after 4, 8, and 16 weeks, respectively. T and N stage were associated with progression, whereas histology, grade, sex, age, and maximum SUV were not. At 3 years, overall survival for Stage III patients with vs. without progression was 18% vs. 67%, p = 0.05. Conclusions: With NSCLC, treatment delay can lead to disease progression. Diagnosis, staging, and treatment initiation should be expedited. After 4-8 weeks of delay, complete restaging should be strongly considered.

    Purpose We conducted a pilot randomized clinical trial of office-based active vision therapy for the treatment of childhood amblyopia to determine the feasibility of conducting a full-scale randomized clinical trial. Methods A training and certification program and manual of procedures were developed to certify therapists to administer a standardized vision therapy program in ophthalmology and optometry offices consisting of weekly visits for 16 weeks. Nineteen children, 7 to less than 13 years of age, with amblyopia (20/40–20/100) were randomly assigned to receive either 2 hours of daily patching with active vision therapy or 2 hours of daily patching with placebo vision therapy. Results Therapists in diverse practice settings were successfully trained and certified to perform standardized vision therapy in strict adherence with protocol. Subjects completed 85% of required weekly in-office vision therapy visits. Eligibility criteria based on age, visual acuity, and stereoacuity, designed to identify children able to complete a standardized vision therapy program and judged likely to benefit from this treatment, led to a high proportion of screened subjects being judged ineligible, resulting in insufficient recruitment. There were difficulties in retrieving adherence data for the computerized home therapy procedures. Conclusions This study demonstrated that a 16-week treatment trial of vision therapy was feasible with respect to maintaining protocol adherence; however, recruitment under the proposed eligibility criteria, necessitated by the standardized approach to vision therapy, was not successful. A randomized clinical trial of in-office vision therapy for the treatment of amblyopia would require broadening of the eligibility criteria and improved methods to gather objective data regarding the home therapy. A more flexible approach that customizes vision therapy based on subject age, visual acuity, and stereopsis, might be required to allow enrollment of a

    2013-01-01

    An investigation of effectiveness of topical treatment of nonhealing chronic venous leg ulcers with propolis ointment was conducted. 56 patients were included in the study and randomized into two groups. In group 1, there were 28 patients (ulceration area: 6.9–9.78 cm2) treated by means of topical propolis ointment application and short stretch bandage compression. In group 2, there were 29 patients (ulceration area: 7.2–9.4 cm2) treated by means of Unna boot leg compression without topical propolis treatment. In the study, the efficacy of both treatment methods in patients with resistive venous leg ulcers was compared. The ulceration of patients from group 1 healed completely after 6 weeks of therapy in all cases. In all patients from group 2, the process of healing was longer but successfully completed after 16 weeks of the therapy. We found that an adjunctive propolis ointment treatment increases the efficacy of the short stretch bandage compression stocking, and this combined treatment is more effective than Unna's boot compression alone.

  9. Periodic and aperiodic synchronization in skilled action.

    PubMed

    Cummins, Fred

    2011-01-01

    Synchronized action is considered as a manifestation of shared skill. Most synchronized behaviors in humans and other animals are based on periodic repetition. Aperiodic synchronization of complex action is found in the experimental task of synchronous speaking, in which naive subjects read a common text in lock step. The demonstration of synchronized behavior without a periodic basis is presented as a challenge for theoretical understanding. A unified treatment of periodic and aperiodic synchronization is suggested by replacing the sequential processing model of cognitivist approaches with the more local notion of a task-specific sensorimotor coordination. On this view, skilled action is the imposition of constraints on the co-variation of movement and sensory flux such that the boundary conditions that define the skill are met. This non-cognitivist approach originates in the work of John Dewey. It allows a unification of the treatment of sensorimotor synchronization in simple rhythmic behavior and in complex skilled behavior and it suggests that skill sharing is a uniquely human trait of considerable import.

  11. Quasi-periodicity in relative quasi-periodic tori

    NASA Astrophysics Data System (ADS)

    Fassò, Francesco; García-Naranjo, Luis C.; Giacobbe, Andrea

    2015-10-01

    At variance from the cases of relative equilibria and relative periodic orbits of dynamical systems with symmetry, the dynamics in relative quasi-periodic tori (namely, subsets of the phase space that project to an invariant torus of the reduced system on which the flow is quasi-periodic) is not yet completely understood. Even in the simplest situation of a free action of a compact and abelian connected group, the dynamics in a relative quasi-periodic torus is not necessarily quasi-periodic. It is known that quasi-periodicity of the unreduced dynamics is related to the reducibility of the reconstruction equation, and sufficient conditions for it are virtually known only in a perturbation context. We provide a different, though equivalent, approach to this subject, based on the hypothesis of the existence of commuting, group-invariant lifts of a set of generators of the reduced torus. Under this hypothesis, which is shown to be equivalent to the reducibility of the reconstruction equation, we give a complete description of the structure of the relative quasi-periodic torus, which is a principal torus bundle whose fibers are tori of a dimension which exceeds that of the reduced torus by at most the rank of the group. The construction can always be done in such a way that these tori have minimal dimension and carry ergodic flow.

    2011-01-01

    Objective A preliminary report on the symptomatic effect of clonidine in severe hyperemesis gravidarum (HG). Design Observational. Settting Hospital based: Ospedale Sant'Anna, Torino, Italy. Population Twelve pregnant women, 8–16 weeks, affected by severe, refractory HG. Methods Assessment by two clinical score indexes: Pregnancy Unique Quantification of Emesis (PUQE) score and a Visual Analogue Scale (VAS) 5-item questionnaire, filled out daily, to detect subjective improvement or worsening of symptoms. Main outcome measures PUQE score and VAS score before and after transdermal clonidine treatment. Results We found substantial improvement of symptoms and severity score indexes after four and 14 days. The comparison of pretreatment and post-treatment scores shows a significant statistical difference P < 0.0001. Conclusion Transdermal clonidine may be considered as a treatment for resistant severe HG.

  16. Testing for periodicity of extinction

    NASA Technical Reports Server (NTRS)

    Raup, David M.; Sepkoski, J. J., Jr.

    1988-01-01

    The statistical techniques used by Raup and Sepkoski (1984 and 1986) to identify a 26-Myr periodicity in the biological extinction record for the past 250 Myr are reexamined, responding in detail to the criticisms of Stigler and Wagner (1987). It is argued that evaluation of a much larger set of extinction data using a time scale with 51 sampling intervals supports the finding of periodicity. In a reply by Sigler and Wagner, the preference for a 26-Myr period is attributed to a numerical quirk in the Harland et al. (1982) time scale, in which the subinterval boundaries are not linear interpolations between the stage boundaries but have 25-Myr periodicity. It is stressed that the results of the stringent statistical tests imposed do not disprove periodicity but rather indicate that the evidence and analyses presented so far are inadequate.

  17. Schuler Period in LEO Satellites

    NASA Technical Reports Server (NTRS)

    Carpenter, Russell J.; Bar-Itzhack, Itzhack Y.

    2004-01-01

    This paper generalizes and extends the concept of the Schuler oscillation that occurs in the theory of inertial navigation systems, allowing one to see how the Schuler phenomenon affects inertial navigation systems operating in space. We show why a low earth orbit satellite's orbital period is identical to the period of the Schuler pendulum, which is the period of the errors for terrestrial inertial navigation systems. We also show that the generalized form of the Schuler oscillation takes the same form as the Hill-Clohessy-Wiltshire equations for satellite relative motion and that the period of the out-of-plane motion in neighboring satellite relative trajectories is the same as the Schuler period. Finally, we describe how INS gyro drift manifests itself in different coordinate systems for the orbital case. These results may assist orbital flight dynamics and attitude control systems engineers in the design and analysis of INS-equipped spacecraft

  18. Rationalization of Comet Halley's periods

    NASA Astrophysics Data System (ADS)

    Belton, M. J. S.

    1990-07-01

    The sense of long axis orientation of Comet Halley during the Vega 1 encounter must be reversed from that deduced by Sagdeev et al. (1986) in order to harmonize the comet nucleus' Vega/Giotto-observed orientations with periodicities extracted from time-series brightness data. It is also demonstrated that Vega/Giotto observations can be satisfied by either a 2.2- or 3.7-day long-axis free precession period. A novel Fourier algorithm is used to reanalyze five independent data sets; strong evidence is adduced for periods harmonically related to a 7.4-day period. The preferred candidate models for Halley's nuclear rotation are characterized by a long-axis precession period of 3.7 days.

  19. LYRA Mid-Term Periodicities

    2016-08-01

    The spectra of the PROBA2/LYRA data, similarly to every other solar time series, show predominant periodicities that can be of solar or instrumental origin. In this article, we compare the main periodicities characterizing the LYRA spectrum to those found in the sunspot number, in the 10.7 cm flux, in an X-ray flare index, and in the sunspot area evolution. We focused on the 2010 to 2014 time range, for which the LYRA data are available, although we also briefly address the evolution of the main periodicities in the longer range. The mid-term periodicities at {˜} 28, {˜} 44, {˜} 54, {˜} 59, {˜} 100, {˜} 110, and {˜} 150 days appear as highly significant in several analyzed datasets. The consistency of distinct periodicities between datasets provides characteristics for the global Sun. This consistency also strengthens the reliability of LYRA data.

  20. Incorporating Spectra Into Periodic Timing

    NASA Astrophysics Data System (ADS)

    Connors, Alanna; Hong, J.; Protopapas, P.; Kashyap, V.

    2011-09-01

    The Chandra surveys have resulted in a wealth of data on low-luminosity X-ray sources (Lx 1030-34 erg/s) of Galactic scales beyond the local solar neighborhood. Many of these are compact binaries, in particular, cataclysmic variables, often identified by their periodic X-ray variability and spectra. Hong et al. (2009, 2011) have used energy quantiles (Hong, Schlegel & Grindlay, 2004) as a fast, robust indicator of spectral hardness and absorption of the X-ray sources. Energy quantiles also enable a simple but effective illustration of spectral changes with phase in these periodic systems: e.g. absorption by the accreting material is understood to drive the periodic light-curves. An interesting question is how to best make use of the information encapsulated in the periodic change in energy spectrum, along with the periodic change in intensity, especially for cases of ambiguous period determination? And, how to do it computationally efficiently? A first approach is to do the period search in intensity, as is standard; and then use a criterion of spectral variation to verify possible periods. Huijse, Zegers & Protopapas (2011) recently demonstrated a powerful period estimation technique using information potential and correntropy embedded in the light curve. Similar quantities based on energies (or energy quantiles) of X-ray photons can serve as criteria of spectral variation. A different approach treats the spectrum variations and intensity variations completely independently, searching through period-space in each, and then combining the results. A more general method would include both at the same time, looking for statistically significant variations above what is expected for a constant (in intensity and spectrum).

  2. A placebo-controlled, double-blind, cross-over trial of flunarizine in common migraine.

    PubMed

    Sørensen, P S; Hansen, K; Olesen, J

    1986-03-01

    After four weeks of medication-free baseline observation, 29 patients with common migraine randomly received flunarizine (10 mg daily) or placebo for a 16-week period. After four weeks wash-out they crossed treatments for another 16 weeks; 27 patients completed the trial. Compared with placebo, flunarizine significantly reduced the frequency of migraine attacks and the derived headache indices, but the duration and severity of single attacks remained unchanged (Mann-Whitney U-test). The effect of flunarizine increased during the 16-week treatment period and during the last four weeks the number of migraine attacks reduced to 50% compared to the wash-out period. The only side-effect of flunarizine was mild daytime sedation in three patients. It is concluded that flunarizine is a valuable new prophylactic agent for common migraine. PMID:3516409

  3. Chaos in Periodic Discrete Systems

    NASA Astrophysics Data System (ADS)

    Shi, Yuming; Zhang, Lijuan; Yu, Panpan; Huang, Qiuling

    This paper focuses on chaos in periodic discrete systems, whose state space may vary with time. Some close relationships between some chaotic dynamical behaviors of a periodic discrete system and its autonomous induced system are given. Based on these relationships, several criteria of chaos are established and some sufficient conditions for no chaos are given for periodic discrete systems. Further, it is shown that a finite-dimensional linear periodic discrete system is not chaotic in the sense of Li-Yorke or Wiggins. In particular, an interesting problem of whether nonchaotic rules may generate a chaotic system is studied, with some examples provided, one of which surprisingly shows that a composition of globally asymptotically stable maps can be chaotic. In addition, some properties of sign pattern matrices of non-negative square matrices are given for convenience of the study.

  5. Substance Use in the Perinatal Period.

    PubMed

    Forray, Ariadna; Foster, Dawn

    2015-11-01

    Perinatal substance use remains a major public health problem and is associated with a number of deleterious maternal and fetal effects. Polysubstance use in pregnancy is common and can potentiate adverse maternal and fetal outcomes. Tobacco is the most commonly used substance in pregnancy, followed by alcohol and illicit substances. The treatments for perinatal substance use are limited and consist mostly of behavioral and psychosocial interventions. Of these, contingency management has shown the most efficacy. More recently, novel interventions such as progesterone for postpartum cocaine use have shown promise. The purpose of this review is to examine the recent literature on the use of tobacco, alcohol, cannabis, stimulants, and opioids in the perinatal period, their effects on maternal and fetal health, and current treatments.

    Kato, Mariko; Saio, Hideyuki; Hachisu, Izumi; Nomoto, Ken'ichi

    2014-10-01

    Stimulated by the recent discovery of the 1 yr recurrence period nova M31N 2008-12a, we examined the shortest recurrence periods of hydrogen shell flashes on mass-accreting white dwarfs (WDs). We discuss the mechanism that yields a finite minimum recurrence period for a given WD mass. Calculating the unstable flashes for various WD masses and mass accretion rates, we identified a shortest recurrence period of about two months for a non-rotating 1.38 M {sub ☉} WD with a mass accretion rate of 3.6 × 10{sup –7} M {sub ☉} yr{sup –1}. A 1 yr recurrence period is realized for very massive (≳ 1.3 M {sub ☉}) WDs with very high accretion rates (≳ 1.5 × 10{sup –7} M {sub ☉} yr{sup –1}). We revised our stability limit of hydrogen shell burning, which will be useful for binary evolution calculations toward Type Ia supernovae.

    Behavioral interventions for autism have gained prominence in recent years; however, the neural-systems-level targets of these interventions remain poorly understood. We use a novel Bayesian framework to extract network-based differences before and after a 16-week pivotal response treatment (PRT) regimen. Our results suggest that the functional changes induced by PRT localize to the posterior cingulate and are marked by a shift in connectivity from the orbitofrontal cortex to the occipital-temporal cortex. Our results illuminate a potential PRT-induced learning mechanism, whereby the neural circuits involved during social perception shift from sensory and attentional systems to higher-level object and face processing areas.

  9. Bragg interactions in periodic media

    Jaggard, D. L.

    1976-01-01

    The interaction of electromagnetic waves of wavelength lambda with periodic structures of spatial period lambda are studied. The emphasis of the work is on Bragg interactions where lambda approximately equal to 2 lambda/N and the Bragg order N takes on the values 1, 2,.... An extended coupled waves (ECW) theory is developed for the case N greater or equal to 2 and the results of the theory are found to compare favorably with the exact results of Floquet theory. Numerous numerical results are displayed as Brillouin diagrams for the first few Bragg orders. Moreover, explicit expressions for coupling coefficients, bandgap shifts and bandgap widths are derived for singly periodic media. Particular note is taken of phase speeding effects.

  10. On composites with periodic structure

    NASA Technical Reports Server (NTRS)

    Nemat-Nasser, S.; Iwakuma, T.; Hejazi, M.

    1982-01-01

    The overall moduli of a composite with an isotropic elastic matrix containing periodically distributed (anisotropic) inclusions or voids, can be expressed in terms of several infinite series which only depend on the geometry of the inclusions or voids, and hence can be computed once and for all for given geometries. For solids with periodic structures these infinite series play exactly the same role as does Eshelby's tensor for a single inclusion or void in an unbounded elastic medium. For spherical and circular-cylindrical geometries, the required infinite series are calculated and the results are tabulated. These are then used to estimate the overall elastic moduli when either the overall strains or the overall stresses are prescribed, obtaining the same results. These results are compared with other estimates and with experimental data. It is found that the model of composites with periodic structure yields estimates in excellent agreement with the experimental observations.

    The periodicity of extinction events is examined in detail. In particular, the temporal distribution of specific, identifiable extinction events is analyzed. The nature and limitations of the data base on the global fossil record is discussed in order to establish limits of resolution in statistical analyses. Peaks in extinction intensity which appear to differ significantly from background levels are considered, and new analyses of the temporal distribution of these peaks are presented. Finally, some possible causes of periodicity and of interdependence among extinction events over the last quarter billion years of earth history are examined.

    A method is proposed for the automatic detection of serial periodicities in a linear sequence. Its application to DNA subtelomeric sequences from two lower eukaryotes, P.falciparum and S.cerevisiae, reveals ordered patterns organised in hierarchical periodicities, not easily recognizable by other methods. The possible implications concerning the evolution of tandemly repetitive arrays are discussed in light of a model which involves, as successive steps, random repeat modification, the fusion of differently modified repeat versions into longer units, and the amplification of (and/or homogenization to) the more recent repeat units.

    PubMed

    Gunlicks-Stoessel, Meredith; Mufson, Laura; Westervelt, Ana; Almirall, Daniel; Murphy, Susan

    2016-01-01

    This pilot study was conducted to assess the feasibility and acceptability of 4 adaptive treatment strategies (ATSs) for adolescent depression to plan for a subsequent full-scale clinical trial. The ATSs aim to address 2 questions that arise when personalizing treatment: (a) For adolescents treated with Interpersonal Psychotherapy for depressed adolescents (IPT-A; Mufson et al., 2004 ), at what time point should therapists make the determination that the adolescent is not likely to respond if the initial treatment plan is continued (week 4 or week 8)? (b) For adolescents who are judged to need their treatment augmented, should the therapist increase the number of IPT-A sessions or add pharmacotherapy (fluoxetine)? A 16-week pilot sequential multiple assignment randomized trial (SMART) was conducted with 32 adolescents (M age = 14.9) who had a diagnosis of major depressive disorder, dysthymic disorder, or depressive disorder not otherwise specified. Adolescents were primarily female (75%) and Caucasian (84.4%). Data regarding the feasibility and acceptability of the study and treatment procedures and treatment response rates were collected. Week 4 was the more feasible and acceptable decision point for assessing need for a change to treatment. Adolescents, parents, and therapists reported a range of attitudes about medication and more intensive therapy as treatment options. Results from the pilot study have yielded additional research questions for the full-scale SMART and will improve our ability to successfully conduct the trial. PMID:25785788

    2012-11-01

    Despite long-standing calls for the individualization of treatments for depression, modest progress has been made in this effort. The primary objective of this study was to test two competing approaches to personalizing cognitive-behavioral treatment of depression (viz., capitalization and compensation). Thirty-four adults meeting criteria for Major Depressive Disorder (59% female, 85% Caucasian) were randomized to 16-weeks of cognitive-behavioral treatment in which strategies used were selected based on either the capitalization approach (treatment matched to relative strengths) or the compensation approach (treatment matched to relative deficits). Outcome was assessed with a composite measure of both self-report (i.e., Beck Depression Inventory) and observer-rated (i.e., Hamilton Rating Scale for Depression) depressive symptoms. Hierarchical linear modeling revealed a significant treatment approach by time interaction indicating a faster rate of symptom change for the capitalization approach compared to the compensation approach (d = .69, p = .03). Personalizing treatment to patients' relative strengths led to better outcome than treatment personalized to patients' relative deficits. If replicated, these findings would suggest a significant change in thinking about how therapists might best adapt cognitive-behavioral interventions for depression for particular patients.

  20. Periodicities of polar cap patches

    2013-01-01

    A highly sensitive all-sky electron multiplier charge-coupled device airglow imager has been operative in Longyearbyen, Norway since October 2011. The imager captures 630.0 nm all-sky images with an exposure time of 4 s, which is about 10 times shorter than that achieved by conventional cooled CCD imagers. This allows us to visualize the structure of polar cap patches without blurring effects and better estimate their periodicities. We present, as one of the first results from the imager, an event of successive appearance of patches on the night of 21 December 2011. A time series of the optical intensity at zenith showed modulations having two distinguished periods, one at 40 min and the other at 5-12 min. One possible explanation is that such a coexistence of two different periodicities is a manifestation of simultaneous occurrence of patch generation processes on the 40 min periodicity was created by large-scale reconfiguration of the dayside convection pattern while the 5-12 min modulations were closely associated with mechanisms driven by pulsed reconnection on the dayside magnetopause. Such a combined effect of multiple patch generation processes may play a role in structuring patches; thus, it would be of particular importance for evaluating the space weather effects in the trans-ionospheric communications environment in the polar cap.

  3. Stability of underwater periodic locomotion

    NASA Astrophysics Data System (ADS)

    Jing, Fangxu; Kanso, Eva

    2013-07-01

    Most aquatic vertebrates swim by lateral flapping of their bodies and caudal fins. While much effort has been devoted to understanding the flapping kinematics and its influence on the swimming efficiency, little is known about the stability (or lack of) of periodic swimming. It is believed that stability limits maneuverability and body designs/flapping motions that are adapted for stable swimming are not suitable for high maneuverability and vice versa. In this paper, we consider a simplified model of a planar elliptic body undergoing prescribed periodic heaving and pitching in potential flow. We show that periodic locomotion can be achieved due to the resulting hydrodynamic forces, and its value depends on several parameters including the aspect ratio of the body, the amplitudes and phases of the prescribed flapping.We obtain closedform solutions for the locomotion and efficiency for small flapping amplitudes, and numerical results for finite flapping amplitudes. This efficiency analysis results in optimal parameter values that are in agreement with values reported for some carangiform fish. We then study the stability of the (finite amplitude flapping) periodic locomotion using Floquet theory. We find that stability depends nonlinearly on all parameters. Interesting trends of switching between stable and unstable motions emerge and evolve as we continuously vary the parameter values. This suggests that, for live organisms that control their flapping motion, maneuverability and stability need not be thought of as disjoint properties, rather the organism may manipulate its motion in favor of one or the other depending on the task at hand.

    Objectives To describe the burden experienced by family caregivers of older adults with depression and to examine the positive effects on caregivers of treating late-life depression. Design Two-phase treatment study for major depressive disorder (MDD) that included 6 weeks of open treatment with antidepressant medication for all older patients followed by 16 weeks of randomized treatment for patients who were partial responders, comparing a combination of medication and interpersonal psychotherapy with medication alone. Setting Primary care and university late-life mental health research clinic. Participants Adults aged 60 and older participating in a randomized trial for treatment of MDD who enrolled in a family caregiver study and their caregiver (N = 244 dyads). Measurements Improvement in patient symptoms during open treatment (lower scores on the Hamilton Rating Scale for Depression (HRSD)) and remission of depression during randomized treatment (3 consecutive weekly HRSD scores of ≤7) were examined as predictors of lower general caregiver burden and burden specific to patient depression. Results Caregivers reported a moderate to high level of general caregiver burden on average. Change in patient depression during open treatment was associated with significantly decreased depression-specific burden (β = −0.22, P =.001) and a trend toward lower general burden (β = − 0.08, P =.08). Caregivers of patients who remitted showed significantly decreased depression-specific burden (F (1,76) = 4.27, P =.04). Conclusion Treatment of late-life depression has benefits that extend to the family members on whom patients depend. Caregiver education and support may strengthen these effects. PMID:19943833

  10. Quantum gates by periodic driving

    2016-01-01

    Topological quantum computation has been extensively studied in the past decades due to its robustness against decoherence. One way to realize the topological quantum computation is by adiabatic evolutions—it requires relatively long time to complete a gate, so the speed of quantum computation slows down. In this work, we present a method to realize single qubit quantum gates by periodic driving. Compared to adiabatic evolution, the single qubit gates can be realized at a fixed time much shorter than that by adiabatic evolution. The driving fields can be sinusoidal or square-well field. With the sinusoidal driving field, we derive an expression for the total operation time in the high-frequency limit, and an exact analytical expression for the evolution operator without any approximations is given for the square well driving. This study suggests that the period driving could provide us with a new direction in regulations of the operation time in topological quantum computation. PMID:26911900

    The optimal Bayes detector for a general periodic waveform having uniform delay and additive white Gaussian noise is examined. It is shown that the detector is much more complex than that for the well known cases of pure sine waves (i.e. classical noncoherent detection) and narrowband signals. An interpretation of the optimal processing is presented, and several implementations are discussed. The results have application to the noncoherent detection of optical square waves.

    1986-01-01

    We report 37 patients ranging in age from 1 month to 14 years treated for intestinal malrotation during a five year period. The main presenting features consisted of intermittent attacks of vomiting (15 patients), failure to thrive (seven), and recurrent colicky abdominal pain (seven). The diagnosis was confirmed by gastrointestinal contrast studies in all but three patients. A standard Ladd's procedure comprised the definitive surgical treatment. We emphasise the poor nutritional state at the time of operation (49% of the cases were on or below the third centile). In contrast with neonatal presentation, volvulus of the midgut occurred in only five patients (14%) compared with 68% in neonates with malrotation. There were two deaths in the series. Ninety four per cent of the remaining patients responded favourably to the operative procedure. Malrotation should be considered in the differential diagnosis of a wide variety of symptoms and should be treated promptly once the diagnosis has been confirmed. PMID:3740908

  15. A Multicenter Randomized Controlled Trial Comparing Treatment of Venous Leg Ulcers Using Mechanically Versus Electrically Powered Negative Pressure Wound Therapy

    PubMed Central

    Marston, William A.; Armstrong, David G.; Reyzelman, Alexander M.; Kirsner, Robert S.

    2015-01-01

    Objective: This study compares two different negative pressure wound therapy (NPWT) modalities in the treatment of venous leg ulcers (VLUs), the ultraportable mechanically powered (MP) Smart Negative Pressure (SNaP®) Wound Care System to the electrically powered (EP) Vacuum-Assisted Closure (V.A.C.®) System. Approach: Patients with VLUs from 13 centers participated in this prospective randomized controlled trial. Each subject was randomly assigned to treatment with either MP NPWT or EP NPWT and evaluated for 16 weeks or complete wound closure. Results: Forty patients (n=19 MP NPWT and n=21 EP NPWT) completed the study. Primary endpoint analysis of wound size reduction found wounds in the MP NPWT group had significantly greater wound size reduction than those in the EP NPWT group at 4, 8, 12, and 16 weeks (p-value=0.0039, 0.0086, 0.0002, and 0.0005, respectively). Kaplan–Meier analyses showed greater acceleration in complete wound closure in the MP NPWT group. At 30 days, 50% wound closure was achieved in 52.6% (10/19) of patients treated with MP NPWT and 23.8% (5/21) of patients treated with EP NPWT. At 90 days, complete wound closure was achieved in 57.9% (11/19) of patients treated with MP NPWT and 38.15% (8/21) of patients treated with EP NPWT. Innovation: These data support the use of MP-NPWT for the treatment of VLUs. Conclusions: In this group of venous ulcers, wounds treated with MP NPWT demonstrated greater improvement and a higher likelihood of complete wound closure than those treated with EP NPWT.

    Late-onset GM2 gangliosidosis is an autosomal recessive, neurodegenerative, lysosomal storage disease, caused by deficiency of ß-hexosaminidase A (Hex A), resulting from mutations in the HEXA (Tay-Sachs variant) or the HEXB (Sandhoff variant) genes. The enzyme deficiency in many patients with juvenile or adult onset forms of the disease results from the production of an unstable protein, which becomes targeted for premature degradation by the quality control system of the smooth endoplasmic reticulum and is not transported to lysosomes. In vitro studies have shown that many mutations in either the α or β subunit of Hex A can be partially rescued, i.e. enhanced levels of both enzyme protein and activity in lysosomes, following the growth of patient cells in the presence of the drug, pyrimethamine. The objectives of the present clinical trial were to establish the tolerability and efficacy of the treatment of late-onset GM2 gangliosidosis patients with escalating doses of pyrimethamine, to a maximum of 100 mg per day, administered orally in a single daily dose, over a 16-week period . The primary objective, tolerability, was assessed by regular clinical examinations, along with a panel of hematologic and biochemical studies. Although clinical efficacy could not be assessed in this short trial, treatment efficacy was evaluated by repeated measurements of leukocyte Hex A activity, expressed relative to the activity of lysosomal ß-glucuronidase. A total of 11 patients were enrolled, 8 males and 3 females, aged 23 to 50 years. One subject failed the initial screen, another was omitted from analysis because of the large number of protocol violations, and a third was withdrawn very early as a result of adverse events which were not drug-related. For the remaining 8 subjects, up to a 4-fold enhancement of Hex A activity at doses of 50 mg per day or less was observed. Additionally marked individual variations in the pharmacokinetics of the drug among the patients were

  17. Haemocytic periodicity and periodic disorders: Periodic neutropenia, thrombocytopenia, lymphocytosis and anaemia

    PubMed Central

    Reimann, Hobart A.

    1971-01-01

    Evidence has accumulated of rhythmic numerical oscillation of each of the blood cells either independently or in combinations. The cyclic changes originate in the marrow of some normal persons and animals without causing illness, and can be induced experimentally. In more than 100 reported instances, periodic oscillations of various cells were accompanied by respective episodes of the disorders named in the title. The disorders may be transitory but usually recur throughout life and occasionally are fatal. All resist therapy. Features in common suggest an interrelationship of the haemal disorders and other disparate heritable periodic diseases. Theoretically, the rhythms are regulated by ubiquitous, inherent, intracellular bioclocks controlled hypothalamically or neurohumorally in relation to a feedback mechanism. Reactions to long cycles are of greater clinical importance than disturbances arising from the circadian rhythm. PMID:4397784

    Takotsubo cardiomyopathy simulates acute myocardial infarction, and it is characterised by reversible left ventricular failure. A case of Takotsubo cardiomyopathy diagnosed after emergency angiography performed in a patient with evidence of acute myocardial infarction in the postoperative period will be described in this report. Transurethral resection of a bladder tumour (TUR-BT) was performed in a 92-year-old male patient by the urology clinic. The patient was transferred to the post-anaesthesia care unit after the operation. An echocardiography was performed because of the sudden onset of dyspnoea, tachycardia (140-150 beats per minute, rhythm-atrial fibrillation) and ST-segment elevation on electrocardiography (ECG) at the first postoperative hour, and midapical dyskinesia was detected at the patient. An immediate angiography was performed due to suspicion of acute coronary syndrome. Patent coronary arteries and temporary aneurysmatic dilatation of the apex of the heart were revealed by angiography. As a result of these findings, the patient was diagnosed with Takotsubo cardiomyopathy by the cardiology service. The patient was discharged uneventfully following 10 days in the intensive care unit. Aneurysm of the apex of the left ventricle and normal anatomy of the coronary arteries in the angiography have diagnostic value for Takotsubo cardiomyopathy. Diuretics (furosemide) and beta-blockers (metoprolol) are commonly used for the treatment of Takotsubo cardiomyopathy. Even though Takotsubo cardiomyopathy is a rare and benign disease, it should be kept in mind in patients suspected for acute myocardial infarction in the postoperative period. PMID:27366464

  4. Rotation period of comet Donati

    1978-01-01

    Consideration is given to the rotation period of comet Donati (1858 VI) whose haloes were approximate parabolic envelopes having foci near the apparent nucleus and vertices toward the sun forward from the tail axis. The regularity and sharpness of the halves suggest that they represent the repetitive ejection of material from an active area which is exposed to solar radiation as the cometary nucleus rotates. Bobrovnikov's results (1954) are used to evaluate the linear expansion velocity of such haloes. This calculation is applied to the comet and a linear correction is used to assess the results.

  5. Long-Period Solar Variability

    SciTech Connect

    GAUTHIER,JOHN H.

    2000-07-20

    Terrestrial climate records and historical observations of the Sun suggest that the Sun undergoes aperiodic oscillations in radiative output and size over time periods of centuries and millenia. Such behavior can be explained by the solar convective zone acting as a nonlinear oscillator, forced at the sunspot-cycle frequency by variations in heliomagnetic field strength. A forced variant of the Lorenz equations can generate a time series with the same characteristics as the solar and climate records. The timescales and magnitudes of oscillations that could be caused by this mechanism are consistent with what is known about the Sun and terrestrial climate.

    We propose a simple approach to determine all possible wheels that can roll smoothly without slipping on a periodic roadbed, while maintaining the center of mass at a fixed height. We also address the inverse problem that of obtaining the roadbed profile compatible with a specific wheel and all other related "quantized wheels." The role of symmetry is highlighted, which might preclude the center of mass from remaining at a fixed height. A straightforward consequence of such geometric quantization is that the gravitational potential energy and the moment of inertia are discrete, suggesting a parallelism between macroscopic wheels and nano-systems, such as carbon nanotubes.

    A periodic permanent magnet (PPM) klystron has beam transport structures and RF cavity structures, each of which has permanent magnets placed substantially equidistant from a beam tunnel formed about the central axis, and which are also outside the extent of a cooling chamber. The RF cavity sections also have permanent magnets which are placed substantially equidistant from the beam tunnel, but which include an RF cavity coupling to the beam tunnel for enhancement of RF carried by an electron beam in the beam tunnel.

    1994-08-01

    A model explaining the presence of a periodic train of microwave absorption lines in the magnetic modulated microwave absorption (MMMA) spectra of high- and low-temperature superconductors is proposed. The model assumes the occurrence of regular superconducting current loops, closed by Josephson junctions, in these materials. The system of such loops is considered within the basic model of the rf superconducting quantum interference device taking into account the effect of thermal fluctuations. The magnetic-field and temperature dependencies of the MMMA obtained on the basis of the proposed model are in qualitative agreement with experimental data.

  17. Periodic bedrock ridges on Mars

    NASA Astrophysics Data System (ADS)

    Montgomery, David R.; Bandfield, Joshua L.; Becker, Scott K.

    2012-03-01

    Evidence for sediment transport and erosion by wind is widespread over the surface of Mars today and was likely a major geomorphic process for much of its geological past. Although Martian surface features resembling aeolian dunes and ripples have been recognized since the Mariner and Viking missions, such features have been interpreted previously as active, indurated, or exhumed sedimentary forms. Here we report evidence based on High Resolution Imaging Science Experiment images that show some megaripple forms are eroded into cohesive substrate rather than being composed of loose granular material or fossilized dunes. Exposure of stratigraphic continuity within layered, cohesive material extending crest to trough through features with mean wavelengths of 18 to 51 m demonstrates the primarily erosional formation of what we term periodic bedrock ridges (PBRs). Hence some surfaces on Mars previously considered to be covered by wind-deposited material are actually wind-carved exposures that offer windows into Martian history. PBRs lack the distinctive streamlining associated with wind-parallel yardangs and comparison of PBR orientation to yardangs, megayardangs, and active sedimentary dunes in the same vicinity confirm that these PBRs formed transverse to prevailing winds. Observed wavelengths of PBRs are comparable to those predicted by a simple model for erosional wavelengths of periodic transverse bed forms owing to the spacing of flow separations within the flow. Recognition of these transverse aeolian erosional forms brings up the question of how widespread Martian PBRs are and how many have been misinterpreted as active or indurated (fossilized) sedimentary dunes.

    Burghouts, Gertjan J; Geusebroek, Jan-Mark

    2006-06-01

    This paper presents the online estimation of temporal frequency to simultaneously detect and identify the quasiperiodic motion of an object. We introduce color to increase discriminative power of a reoccurring object and to provide robustness to appearance changes due to illumination changes. Spatial contextual information is incorporated by considering the object motion at different scales. We combined spatiospectral Gaussian filters and a temporal reparameterized Gabor filter to construct the online temporal frequency filter. We demonstrate the online filter to respond faster and decay faster than offline Gabor filters. Further, we show the online filter to be more selective to the tuned frequency than Gabor filters. We contribute to temporal frequency analysis in that we both identify ("what") and detect ("when") the frequency. In color video, we demonstrate the filter to detect and identify the periodicity of natural motion. The velocity of moving gratings is determined in a real world example. We consider periodic and quasiperiodic motion of both stationary and nonstationary objects. PMID:16764282

    Background Memantine hydrochloride is a N-methyl-D-aspartate (NMDA) antagonist that may be useful in the treatment of Alzheimer's disease. Aim Compare the efficacy and safety of generic memantine hydrochloride produced in China to that of the imported proprietary version of the medication (Ebixa) in the treatment of moderate to severe Alzheimer's disease (AD). Methods In this multicenter, double-blind randomized controlled trial 229 patients with moderate to severe AD were randomly assigned to a 16-week trial of either the generic preparation or the proprietary preparation of memantine hydrochloride. All participants were assessed at baseline and at 4, 8, 12 and 16 weeks after enrolment. The primary outcome variable was the Alzheimer Disease Assessment Scale-cognition (ADAS-Cog) score. Secondary outcomes were scores in the Mini-Mental State Examination (MMSE), the Activities of Daily Living (ADL) scale and the Clinical Global Impression (CGI) scale. Results Sample sizes for the safety set (SS) analysis, full analysis set (FAS) and per protocol set (PPS) analysis were 112, 109 and 103 in the generic medication group, and 111, 107 and 101 in the proprietary medication group, respectively. The ADAS-Cog and ADL total scores at the end of weeks 4, 8, 12, and 16 decreased significantly compared with baseline for both groups (p<0.001) and the MMSE total scores at the end of weeks 4, 8, 12, and 16 increased significantly compared with baseline for both groups (p<0.001). There were no significant differences in ADAS-Cog total scores, ADL total scores and level of improvement based on the CGI scores between the two groups at any of the follow-up assessments.

    A randomized, placebo-controlled study was conducted examining the singular and combined effects of fluoxetine and a self-help manual on suppressing bulimic behaviors in women with bulimia nervosa. A total of 91 adult women with bulimia nervosa were randomly assigned to one of four conditions: placebo only, fluoxetine only, placebo and a self-help manual, or fluoxetine and a self-help manual. Subjects were treated for 16 weeks. Primary outcome measures included self-reports of bulimic behaviors. Fluoxetine and a self-help manual were found to be effective in reducing the frequency of vomiting episodes and in improving the response rates for vomiting and binge-eating episodes. Furthermore, both factors were shown to be acting additively on the primary and secondary efficacy measures in this study. Results are discussed in relation to previous research and the implications for treatment of bulimia nervosa. PMID:11386493

    Research suggests that the sequelae of childhood anxiety disorders, if left untreated, can include chronic anxiety, depression, and substance abuse. The current study evaluated the maintenance of outcomes of children who received a 16-week cognitive-behavioral treatment for primary anxiety disorders (generalized, separation, and social anxiety disorders) an average of 7.4 years earlier. The 86 participants (ages 15 to 22 years; 91% of the original sample) and their parents completed diagnostic interviews and self- and parent-report measures. According to the diagnostic interviews, a meaningful percentage of participants maintained significant improvements in anxiety at long-term follow-up. With regard to sequelae, positive responders to anxiety treatment, as compared with less positive responders, had a reduced amount of substance use involvement and related problems at long-term follow-up. The findings are discussed with regard to child anxiety and some of its sequelae. PMID:15065961

    Cognitive behavioral treatment (CBT) is the recommended intervention in bulimia nervosa (BN) and eating disorders not otherwise specified with binge/purge (EDNOS-B/P) symptoms. There are fewer data on its application in a group format. We sought to investigate the effect of group CBT in female soldiers with B/P symptomatology in an open trial design. For this purpose we assessed 64 female soldiers serving in the Israeli Defense Force diagnosed with BN and EDNOS-B/P who participated in a group CBT format of 16 weekly sessions and one follow-up session. In this study, 42 participants (65.6%) completed treatment and 22 participants (34.4%) did not. A total of 39 treatment completers (92.8% of treatment completers) and 19 non-completers (86.4% of treatment non-completers) were assessed around 12 months after treatment. Participants completed at baseline and following treatment questionnaires assessing eating-related symptoms, depression, anxiety, and overall functioning. At follow-up they were assessed for eating-related symptoms. Our findings show only minimal baseline differences between treatment completers and non-completers. Significant improvement from baseline to post-treatment was shown for B/P and restrictive symptoms, depression, anxiety, and overall functioning. At that time, more than a third of treatment completers were abstinent from binging and more than a half from vomiting. The improvement in B/P and restricting symptoms was maintained at 1 year follow-up for treatment completers. At that time around 60% were abstinent from binging and more than 70% from vomiting. Participants not completing treatment were also improved at follow-up but to a lesser extent. The findings of the present study suggest that group CBT may be effective for the treatment of female soldiers with BN and EDNOS-B/P. PMID:27128883

    The discovery of a new class of Navier-Stokes solutions representing steady periodic stretched vortices offers a useful test-bed for examining interactions between flames and complex flow-fields. After briefly describing these vortex solutions and their wide-ranging parameterization in terms of wavelength and amplitude, this article examines their effect on flames of constant normal propagation speed as observed through numerical solutions of an eikonal equation. Over certain ranges of vortex amplitude and flame-speed, a corridor of enhanced flame passage is seen to be created as a leading flame-tip managers to leap-frog between successive vortices. However, for large enough amplitudes of vorticity or small enough flame-speeds, the flame fails to be able to benefit from the advection due to the vortices. It is shown that the leading tips of such flames are effectively trapped by the stretched vortices.

    The D-dimensional Coulomb system serves as a starting point for generating generalized atomic shells. These shells are ordered according to a generalized Madelung rule in D dimensions. This rule together with an Aujbau Prinzip is applied to produce a D-dimensional periodic table. A model is developed to rationalize the ordering of the shells predicted by the generalized Madelung rule. This model is based on the introduction of a Hamiltonian, invariant under the q-deformed algebra U{sub q}(so(D)), that breaks down the SO(D + 1) dynamical symmetry of the hydrogen atom in D dimensions. The D = 2 case (Flatland) is investigated in some detail. It is shown that the neutral atoms and the (moderately) positive ions correspond to the values q = 0.8 and q = 1, respectively, of the deformation parameter q. 55 refs.

    The high energy demands of dairy cows during the transition period from late gestation into early lactation can place them at an increased risk for the development of metabolic and infectious diseases. Modification of the dry period diet has been investigated as a preventive means to minimize the detrimental aspects of metabolic shifts during the transition period. Studies investigating the impact of dry period diet on lipid parameters during the transition period have largely focused on markers of lipolysis and ketogenesis. Total cholesterol declines during the periparturient period and increases in early lactation. The impact total energy in the dry period diet has on the ability of the cow to maintain total serum cholesterol, as well as its natural high-density lipoprotein-rich status, during this metabolically challenging window is not clear. The impact of lipoproteins on inflammation and immune function may have a clinical impact on the cow's ability to ward off production-related diseases. In this study, we hypothesized that the provision of adequate, but not excessive, total metabolizable energy, would better allow the cow to maintain total cholesterol and a higher relative proportion of HDL throughout the transition period. Cows were allocated to one of three dry period dietary treatment groups following a randomized block design. Total serum triglycerides, cholesterol and lipoprotein fractions were measured on a weekly basis from approximately 7 weeks pre-calving to 6 weeks post-calving. The cows on the high energy diet maintained total serum cholesterol as compared to the cows provided a lower energy diet, but there was no significant increase in the LDL fraction of lipoproteins between diet treatment groups.

    Purpose of Review This review summarizes significant advances in the epidemiology, pathophysiology, and treatment of congenital hypothyroidism (CH), with a focus on thyroid dysfunction in preterm infants. Recent Findings CH appears to be increasing in incidence, primarily due to increased stringency of screening strategies, with smaller contributions from changing demographics and improved survival of increasingly premature infants. The greatest increase has been in mildly affected infants. Although many such cases are transient, some eventually prove to be severe and/or permanent. In preterm infants, transient hypothyroidism is common and may be delayed in onset. The etiology is probably multifactorial, and inadequate iodine intake may contribute to some cases. Transient hypothyroxinemia of prematurity (THOP), also common in premature infants, is correlated with markers of inflammation. Despite concern about the potential morbidity of THOP, the benefits and safety of treatment have not been established. Novel genetic causes of CH continue to be identified, and accumulating data support the sensitivity of infants with severe CH to small changes in levothyroxine formulation. Summary Changes in newborn screening strategies have increasingly identified thyroid function abnormalities of unclear clinical significance. Novel causes of CH continue to be identified, and new data continue to emerge regarding optimal therapy. PMID:23974774

    Critical period of weed control is the foundation of integrated weed management and, hence, can be considered the first step to design weed control strategy. To determine critical period of weed control of aerobic rice, field trials were conducted during 2010/2011 at Universiti Putra Malaysia. A quantitative series of treatments comprising two components, (a) increasing duration of weed interference and (b) increasing length of weed-free period, were imposed. Critical period was determined through Logistic and Gompertz equations. Critical period varied between seasons; in main season, it started earlier and lasted longer, as compared to off-season. The onset of the critical period was found relatively stable between seasons, while the end was more variable. Critical period was determined as 7-49 days after seeding in off-season and 7-53 days in main season to achieve 95% of weed-free yield, and 23-40 days in off-season and 21-43 days in main season to achieve 90% of weed-free yield. Since 5% yield loss level is not practical from economic view point, a 10% yield loss may be considered excellent from economic view point. Therefore, aerobic rice should be kept weed-free during 21-43 days for better yield and higher economic return. PMID:22778701

  20. Gauge interaction as periodicity modulation

    2012-06-01

    The paper is devoted to a geometrical interpretation of gauge invariance in terms of the formalism of field theory in compact space-time dimensions (Dolce, 2011) [8]. In this formalism, the kinematic information of an interacting elementary particle is encoded on the relativistic geometrodynamics of the boundary of the theory through local transformations of the underlying space-time coordinates. Therefore gauge interactions are described as invariance of the theory under local deformations of the boundary. The resulting local variations of the field solution are interpreted as internal transformations. The internal symmetries of the gauge theory turn out to be related to corresponding space-time local symmetries. In the approximation of local infinitesimal isometric transformations, Maxwell's kinematics and gauge invariance are inferred directly from the variational principle. Furthermore we explicitly impose periodic conditions at the boundary of the theory as semi-classical quantization condition in order to investigate the quantum behavior of gauge interaction. In the abelian case the result is a remarkable formal correspondence with scalar QED.

    2015-01-01

    The perioperative period is characterized by profound changes in the body's homoeostatic processes. This review seeks to address whether epigenetic mechanisms may influence an individual's reaction to surgery and anaesthesia. Evidence from animal and human studies suggests that epigenetic mechanisms can explain many facets of susceptibility to acute and chronic pain, making them potential therapeutic targets. Modern pain management is still based upon opiates, and both the developmental expression of opioid receptors and opioid-induced hyperalgesia have been linked to epigenetic mechanisms. In general, opiates seem to increase global DNA methylation levels. This is in contrast to local anaesthetics, which have been ascribed a global demethylating effect. Even though no direct investigations have been carried out, the potential influence of epigenetics on the inflammatory response that follows surgery seems a promising area for research. There is a considerable body of evidence that supports the involvement of epigenetics in the complex process of wound healing. Epigenetics is an important emerging research topic in perioperative medicine, with a huge potential to positively influence patient outcome. PMID:25073649

    Dense packings of nonoverlapping bodies in three-dimensional Euclidean space R3 are useful models of the structure of a variety of many-particle systems that arise in the physical and biological sciences. Here we investigate the packing behavior of congruent ring tori in R3, which are multiply connected nonconvex bodies of genus 1, as well as horn and spindle tori. Specifically, we analytically construct a family of dense periodic packings of unlinked tori guided by the organizing principles originally devised for simply connected solid bodies [22 Torquato and Jiao, Phys. Rev. E 86, 011102 (2012), 10.1103/PhysRevE.86.011102]. We find that the horn tori as well as certain spindle and ring tori can achieve a packing density not only higher than that of spheres (i.e., π /√18 =0.7404...) but also higher than the densest known ellipsoid packings (i.e., 0.7707...). In addition, we study dense packings of clusters of pair-linked ring tori (i.e., Hopf links), which can possess much higher densities than corresponding packings consisting of unlinked tori.

    In grazing cattle, infections with gastrointestinal nematodes pose some of the most important health threats and subclinical infections result in considerable production losses. While there is little doubt that climate change will affect grazing ruminants directly, mean temperature increases of ∼3°C and longer drought stress periods in summer may also influence the free-living stages of parasitic nematodes. Hostile climatic conditions reduce the number of L3s on pasture and therefore the refugium, which is expected to result in a higher selection pressure, accelerating development of resistance against anthelmintic drugs. The aim of the current experiments was to investigate the effects of drought stress and different temperature/humidity ranges over time on the survival and fitness of Cooperia oncophora L3s and their distribution in grass and soil under controlled conditions using a climate chamber. Grass containers inoculated with L3s were analysed after 1-6weeks using descriptive statistics as well as linear models. A large proportion of L3s was recovered from soil where fitness was also better preserved than on grass. Numbers and fitness of recovered L3s declined with duration in the climate chamber under both temperature profiles. However, the results of the linear models confirmed that higher temperatures (20-33°C versus 17-22.6°C) significantly impaired survival, distribution and fitness of L3s. Application of drought stress, known as another important factor, had a surprisingly smaller impact than its duration or higher temperatures. The climate chamber enabled exclusion of confounding factors and therefore accurate interpretation of the investigated climatic aspects. The obtained results highlight the relative importance of those factors, and will help to design better models for the population dynamics of L3s on pasture in the future. Additionally, the outcomes of these investigations may offer explanations regarding interdependencies of development

    Four nights of photoelectric observations of the delta Scuti star HR 1225 have been obtained. The light curve has a variable amplitude envelope indicating that more than one period is present. A search for periodicities using the Jurkevich method and Fourier analysis suggests periods of 0.156 d and 0.097 d. A least-squares solution yields a fair fit to the data with these two periods. The Fourier transform suggests that three periods are present.

    Typical symptoms of bronchiectasis include cough, sliminess of the airways and recurrent respiratory infections which lead to lung injury and impaired quality of life when untreated. High-resolution computer tomography is the most important examination to detect bronchiectasias. Cornerstones of the treatment are elucidation of the etiology of the disease, taking care of vaccinations, management of physical fitness, treating sliminess, and careful treatment of periods of exacerbation with antibiotics according to bacterial growth and susceptibility testing determined from sputum. Hypertonic saline inhalation can be used to potentiate the treatment of sliminess and achieve a positive effect on the quality of life. PMID:24822326

    Forty-eight multiparous cows were used in a randomized complete block design experiment with a 2×2 factorial arrangement of treatments to determine the interaction between chromium propionate (CrPr) supplementation and sources of corn varying in ruminal starch fermentability on production responses during the postpartum (PP) and carryover periods. During the peripartum period (28d before expected parturition until 28d PP), diets were top-dressed (20g/d) with either CrPr (KemTRACE Chromium Propionate, Kemin Industries, Des Moines, IA; 8mg of Cr/cow per day) or control (Con; ground corn). At parturition, cows were randomly assigned to corn treatment within CrPr and Con treatments: dry corn (DC) or high-moisture corn (HMC). Treatment combinations (CrPr/DC, CrPr/HMC, Con/DC, and Con/HMC) were fed from parturition until 28d PP (treatment period). Cows were fed a common diet to evaluate potential carryover effects of the treatment diets from 29 to 84d PP (carryover period). The CrPr and corn treatments interacted over time to affect yield of 3.5% fat-corrected milk (FCM) during both the treatment and carryover periods. The CrPr/HMC treatment combination tended to increase FCM compared with Con/DC and Con/HMC by 28d PP (57.4 vs. 48.6 and 48.5kg/d, respectively) and increased FCM compared with Con/DC by 42d PP (59.2 vs. 44.8kg/d). The CrPr tended to increase milk yield (55.4 vs. 51.9kg/d) regardless of corn source during the carryover period after treatment ceased. Daily and cumulative DMI were not affected by treatment during the PP period, but CrPr and corn treatments interacted over time to affect daily DMI during the carryover period; DMI was generally higher for CrPr/HMC, lower for Con/DC, and intermediate for CrPr/DC and Con/HMC from 29 to 84d PP. Supplementation of CrPr throughout the peripartum period interacted with starch source in PP diets over time to affect production responses that were sustained after treatment application ceased.

    1976-01-01

    A reliability analysis of structures subjected to random service loads and periodic proof tests treats gust loads and maneuver loads as random processes. Crack initiation, crack propagation, and strength degradation are treated as the fatigue process. The time to fatigue crack initiation and ultimate strength are random variables. Residual strength decreases during crack propagation, so that failure rate increases with time. When a structure fails under periodic proof testing, a new structure is built and proof-tested. The probability of structural failure in service is derived from treatment of all the random variables, strength degradations, service loads, proof tests, and the renewal of failed structures. Some numerical examples are worked out.

    We examine the efficiency-based arguments for second-best optimal health insurance with multiple treatment goods and multiple time periods. Correlated shocks across health care goods and over time interact with complementarity and substitutability to affect optimal cost sharing. Health care goods that are substitutes or have positively correlated demand shocks should have lower optimal patient cost sharing. Positive serial correlations of demand shocks and uncompensated losses that are positively correlated with covered health services also reduce optimal cost sharing. Our results rationalize covering pharmaceuticals and outpatient spending more fully than is implied by static, one good, or one period models. PMID:25727031

    This study aimed to evaluate the efficacy and safety of Ganoderma lucidum for the treatment of hyperglycaemia and other cardiovascular risk components of metabolic syndrome using a prospective, double-blind, randomised, placebo-controlled trial. Eighty-four participants with type 2 diabetes mellitus and metabolic syndrome were randomised to one of three intervention groups: Ganoderma lucidum, Ganoderma lucidum with Cordyceps sinensis, or placebo. The dosage was 3 g/day of Ganoderma lucidum, with or without Cordyceps sinensis, for 16 weeks. The primary outcome measure was blood glucose (glycosylated haemoglobin [HbA1c] and fasting plasma glucose [FPG]); a number of secondary outcome measures were also tested. Data from the two intervention groups were combined. The combined intervention had no effect on any of the primary (baseline-adjusted difference in means: HbA1c = 0.13%, 95% CI [-0.35, 0.60], p = 0.60; FPG = 0.03 mmol/L, 95% CI [-0.90, 0.96], p = 0.95) or secondary outcome measures over the course of the 16-week trial, and no overall increased risk of adverse events with either active treatment. Evidence from this randomised clinical trial does not support the use of Ganoderma lucidum for treatment of cardiovascular risk factors in people with diabetes mellitus or metabolic syndrome.

    This study aimed to evaluate the efficacy and safety of Ganoderma lucidum for the treatment of hyperglycaemia and other cardiovascular risk components of metabolic syndrome using a prospective, double-blind, randomised, placebo-controlled trial. Eighty-four participants with type 2 diabetes mellitus and metabolic syndrome were randomised to one of three intervention groups: Ganoderma lucidum, Ganoderma lucidum with Cordyceps sinensis, or placebo. The dosage was 3 g/day of Ganoderma lucidum, with or without Cordyceps sinensis, for 16 weeks. The primary outcome measure was blood glucose (glycosylated haemoglobin [HbA1c] and fasting plasma glucose [FPG]); a number of secondary outcome measures were also tested. Data from the two intervention groups were combined. The combined intervention had no effect on any of the primary (baseline-adjusted difference in means: HbA1c = 0.13%, 95% CI [−0.35, 0.60], p = 0.60; FPG = 0.03 mmol/L, 95% CI [−0.90, 0.96], p = 0.95) or secondary outcome measures over the course of the 16-week trial, and no overall increased risk of adverse events with either active treatment. Evidence from this randomised clinical trial does not support the use of Ganoderma lucidum for treatment of cardiovascular risk factors in people with diabetes mellitus or metabolic syndrome. This Clinical Trial was registered with the Australian New Zealand Clinical Trials Registry on November 23, 2006.

    Background Antipsychotic-treated youth have increased risk for the development of obesity and type 2 diabetes. Behavioral weight loss treatments show promise in reducing obesity and diabetes risk in antipsychotic treated adults, but have received no study in antipsychotic treated youth. Objective We describe a rationale for behavioral weight loss interventions in high-weight antipsychotic treated youth, and report behavioral, anthropomorphic, and metabolic findings from a case series of obese antipsychotic-treated adolescents participating in a short-term, family-based behavioral weight loss intervention. Methods We adapted the Traffic Light Plan, a 16-week family-based weight loss intervention that promotes healthy energy balance using the colors of the traffic light to categorize the nutritional value of foods and intensity of physical activity, adapting a social ecological framework to address health behavior change in multiple social contexts. The intervention was administered to three obese adolescents with long-term antipsychotic medication exposure. Efficacy of the intervention was evaluated with a battery of anthropomorphic and metabolic assessments including weight, body mass index percentile, whole body adiposity, liver fat content, and fasting plasma glucose and lipids. Participants and their parents also filled out a treatment satisfaction questionnaire upon study completion. Results Two males and 1 female (all aged 14 years) participated. All 3 participants attended all 16 sessions, and experienced beneficial changes in adiposity, fasting lipids and liver fat content associated with weight stabilization or weight loss. Adolescents and their parents all reported a high level of satisfaction with the treatment. Conclusions Family-based behavioral weight loss treatment can be feasibly delivered and is acceptable to antipsychotic-treated youth and their families. Randomized controlled trials are needed to fully evaluate the effectiveness and acceptability

  13. Dearth of short-period Neptunian exoplanets: A desert in period-mass and period-radius planes

    A few studies have reported a significant dearth of exoplanets with Neptune mass and radius with orbital periods below 2-4 d. This cannot be explained by observational biases because many Neptunian planets with longer orbital periods have been detected. The existence of this desert is similar to the appearance of the so-called brown-dwarf desert that suggests different formation mechanisms of planets and stellar companions with short orbital periods. Similarly, the Neptunian desert might indicate different mechanisms of formation and evolution for hot Jupiters and short-period super-Earths. We here follow a previous study and examine the location and shape of the desert in both the period-mass and period-radius planes, using the currently available large samples of planets. The desert in the period-mass plane has a relatively sharp upper edge, with a planetary mass that is inversely proportional to the planetary orbital period, while the lower, somewhat blurred, boundary is located along masses that are apparently linearly proportional to the period. The desert in the period-radius plane of the transiting planets is less clear. It seems as if the radius along the upper boundary is inversely proportional to the period to the power of one-third, while the lower boundary shows a radius that is proportional to the period to the power of two-thirds. The combination of the two upper bounds of the desert, in the period-mass and period-radius planes, yields a planetary mass-radius relation of Rp/RJup ≃ (1.2 ± 0.3)(Mp/MJup)0.27 ± 0.11 for 0.1 ≲ Mp/MJup ≲ 1. The derived shape of the desert, which might extend up to periods of 5-10 d, could shed some light on the formation and evolution of close-in planets.

    The pathophysiology of acne vulgaris depends on active sebaceous glands, implying that selective destruction of sebaceous glands could be an effective treatment. We hypothesized that light-absorbing microparticles could be delivered into sebaceous glands, enabling local injury by optical pulses. A suspension of topically applied gold-coated silica microparticles exhibiting plasmon resonance with strong absorption at 800 nm was delivered into human pre-auricular and swine sebaceous glands in vivo, using mechanical vibration. After exposure to 10-50 J cm(-2), 30 milliseconds, 800 nm diode laser pulses, microscopy revealed preferential thermal injury to sebaceous follicles and glands, consistent with predictions from a computational model. Inflammation was mild; gold particles were not retained in swine skin 1 month after treatment, and uptake in other organs was negligible. Two independent prospective randomized controlled clinical trials were performed for treatment of moderate-to-severe facial acne, using unblinded and blinded assessments of disease severity. Each trial showed clinically and statistically significant improvement of inflammatory acne following three treatments given 1-2 weeks apart. In Trial 2, inflammatory lesions were significantly reduced at 12 weeks (P=0.015) and 16 weeks (P=0.04) compared with sham treatments. Optical microparticles enable selective photothermolysis of sebaceous glands. This appears to be a well-tolerated, effective treatment for acne vulgaris. PMID:25748556

  16. Periodic Poisson model for beam dynamics simulation

    2016-03-01

    A method is described to solve the Poisson problem for a three dimensional source distribution that is periodic into one direction. Perpendicular to the direction of periodicity a free space (or open) boundary condition is realized. In beam physics, this approach allows us to calculate the space charge field of a continualized charged particle distribution with periodic pattern. The method is based on a particle-mesh approach with equidistant grid and fast convolution with a Green's function. The periodic approach uses only one period of the source distribution, but a periodic extension of the Green's function. The approach is numerically efficient and allows the investigation of periodic- and pseudoperiodic structures with period lengths that are small compared to the source dimensions, for instance of laser modulated beams or of the evolution of micro bunch structures. Applications for laser modulated beams are given.

  17. CONSUMING A BALANCED HIGH FAT DIET FOR 16 WEEKS IMPROVES BODY COMPOSITION, INFLAMMATION AND VASCULAR FUNCTION PARAMETERS IN OBESE PREMENOPAUSAL WOMEN

    Objective Inflammation, insulin resistance and vascular dysfunction characterize obesity and predict development of cardiovascular disease (CVD). Although women experience CVD events at an older age, vascular dysfunction is evident 10 years prior to coronary artery disease. Questions remain whether replacing SFA entirely with MUFA or PUFA is the optimal approach for cardiometabolic benefits. This study tested the hypotheses that: a) body composition, inflammation and vascular function would improve with a high fat diet (HFD) when type of fat is balanced as 1/3 SFA, 1/3 MUFA and 1/3 PUFA; and b) body composition, inflammation and vascular function would improve more when balanced HFD is supplemented with 18C fatty acids, in proportion to the degree of 18C unsaturation. Methods Obese premenopausal women were stabilized on balanced HFD and randomized to consume 9 g/d of encapsulated stearate (18:0), oleate (18:1), linoleate (18:2) or placebo. Results Significant improvements occurred in fat oxidation rate (↑6%), body composition (%fat: ↓2.5 ± 2.1%; %lean: ↑2.5 ± 2.1%), inflammation (↓ IL-1α, IL-1β, 1L-12, Il-17, IFNγ, TNFα, TNFβ) and vascular function (↓BP, ↓PAI-1, ↑tPA activity). When compared to HFD+placebo, HFD+stearate had the greatest effect on reducing IFNγ (↓74%) and HFD+linoleate had the greatest effect on reducing PAI-1 (↓31%). Conclusions Balancing the type of dietary fat consumed (SFA/MUFA/PUFA) is a feasible strategy to positively affect markers of CVD risk. Moreover, reductions in inflammatory molecules involved in vascular function might be enhanced when intake of certain 18C fatty acids is supplemented. Long term effects need to be determined for this approach. PMID:24559846

    We formulate and prove a periodic analog of Maxwell’s theorem relating stressed planar frameworks and their liftings to polyhedral surfaces with spherical topology. We use our lifting theorem to prove deformation and rigidity-theoretic properties for planar periodic pseudo-triangulations, generalizing features known for their finite counterparts. These properties are then applied to questions originating in mathematical crystallography and materials science, concerning planar periodic auxetic structures and ultrarigid periodic frameworks.

    It has been suggested for some time that circadian rhythm abnormalities underlie the development of multiple psychiatric disorders. However, it is unclear how disruptions in individual circadian genes might regulate mood and anxiety. Here we found that mice lacking functional mPeriod 1 (mPer1) or mPeriod 2 (mPer2) individually did not have consistent behavioral abnormalities in measures of anxiety-related behavior. However, mice deficient in both mPer1 and mPer2 had an increase in levels of anxiety-like behavior in multiple measures. Moreover, we found that mPer1 and mPer2 expression was reduced in the nucleus accumbens (NAc) after exposure to chronic social defeat stress, a paradigm that led to increased anxiety-related behavior. Following social defeat, chronic treatment with fluoxetine normalized Per gene expression towards wild-type levels. Knockdown of both mPer1 and mPer2 expression via RNA interference specifically in the NAc led to a similar increase in anxiety-like behavior as seen in the mutant animals. Taken together, these results implicate the Per genes in the NAc in response to stress and the development of anxiety. PMID:23039899

    Classical periodic orbits are stationary-phase points in path integral representations of quantum propagators. We show that complex solutions of the stationary-phase equation, not corresponding to real classical periodic orbits, give additional contributions to the propagator which can be important, especially near bifurcations. We reveal the existence and relevance of such periodic ghost orbits for a kicked top.

  1. A rare case of thyrotoxic periodic paralysis precipitated by hydrocortisone

    PubMed Central

    Chakrabarti, Subrata

    2015-01-01

    Thyrotoxic periodic paralysis (TPP) is a rare, but serious condition characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Although carbohydrate rich meals, strenuous exercise, alcohol, emotional stress are known precipitants of TPP, steroid treatment has rarely been reported to induce TPP. We report a case in which a patient with previously untreated Grave's disease developed TPP following administration of Intravenous hydrocortisone for control of severe anaphylaxis, which to best of our knowledge is very rare.

    Thyrotoxic hypokalemic periodic paralysis is characterized by attacks of generalized weakness associated to hypokalemia in patients with hyperthyroidism. We report a 25-year-old man with a history of spontaneously relapsing episodes of muscular weakness, who consulted for a rapidly evolving upper and lower limb paresis. Hypokalemia associated to a primary hyperthyroidism was detected. Treatment with antithyroid Drugs and potassium supplementation reverted symptoms and the episodes of acute muscular weakness did not reappear. PMID:21279257

  3. Analysis of intermittent periodic modes within complex data

    NASA Astrophysics Data System (ADS)

    Wang, Huang-Xin; de Paola, Robert; Norwood, William I.

    1993-11-01

    We propose a new analytical technique, cycle length analysis (CLA), which quantifies all intermittent periodic modes of a data set. CLA is especially well suited to the treatment of extended measurements of complex physical, chemical, and biological systems when subjected to variations in underlying dynamical parameters which cannot be controlled precisely or monitored accurately. We demonstrate the application of CLA using (1) a coupled oscillator model under the conditions of continuously varying control parameters and (2) clinical cardiac rhythm data.

    Perinatal period may pose a great challenge for the clinical management and treatment of psychiatric disorders in women. In fact, several mental illnesses can arise during pregnancy and/or following childbirth. Suicide has been considered a relatively rare event during the perinatal period. However, in some mental disorders (i.e., postpartum depression, bipolar disorder, postpartum psychosis, etc.) have been reported a higher risk of suicidal ideation, suicide attempt, or suicide. Therefore, a complete screening of mothers’ mental health should also take into account thoughts of suicide and thoughts about harming infants as well. Clinicians should carefully monitor and early identify related clinical manifestations, potential risk factors, and alarm symptoms related to suicide. The present paper aims at providing a focused review about epidemiological data, risk factors, and an overview about the main clinical correlates associated with the suicidal behavior during the pregnancy and postpartum period. Practical recommendations have been provided as well. PMID:27570512

  5. [Popular knowledge about medicaments in 19th century periodicals].

    PubMed

    Arabas, Iwona

    2004-01-01

    Polish periodicals published since the beginning of 19th century contained household knowledge which was of great importance to peasants. In the second half of 19th century the number of articles related to prevention, treatment as well as life hygiene (including nutrition guidance) enlarged significantly. The term "household medicine box# was very often used in periodicals as titles of both: sections dedicated to hygiene or medicine as well as for articles describing medicaments intended to be kept in the boxes. Articles referenced law regulations stated in "law for pharmacists and pharmacies# from 1844. The availability of medical handbooks widened with the end of the century and this fact may have caused the changes in profiles of numerous medical sections in popular periodicals. However the changes did not affect publications related to contents of medical boxes. PMID:17152882

  11. Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome.

    PubMed

    Ali, Nora S; Sartori-Valinotti, Julio C; Bruce, Alison J

    2016-01-01

    Periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome, the most common periodic disorder of childhood, presents with the cardinal symptoms of periodic fever, aphthous stomatitis, pharyngitis, and adenitis typically before age 5. This review presents the recent literature on PFAPA and summarizes key findings in the pathogenesis, evaluation, and treatment of the disease. Theories surrounding the pathogenesis of PFAPA include a faulty innate immunologic response in conjunction with dysregulated T-cell activation. A potential genetic link is also under consideration. Mediterranean fever (MEFV) gene variants have been implicated and appear to modify disease severity. In individuals with the heterozygous variant, PFAPA episodes are milder and shorter in duration. Diagnostic criteria include the traditional clinical signs, in addition to the following biomarkers: elevated C-reactive protein in the absence of elevated procalcitonin, vitamin D, CD64, mean corpuscular volume, and other nonspecific inflammatory mediators in the absence of an infectious explanation for fever. Treatment of PFAPA includes tonsillectomy, a single dose of corticosteroids, and, most recently, interleukin 1 blockers such as anakinra, rilonacept, and canakinumab. Tonsillectomy remains the only permanent treatment modality. PMID:27343963

  12. Light period regulation of carbohydrate partitioning

    NASA Technical Reports Server (NTRS)

    Janes, Harry W.

    1994-01-01

    We have shown that the photosynthetic period is important in regulating carbon partitioning. Even when the same amount of carbon is fixed over a 24h period considerably more is translocated out of the leaf under the longer photosynthetic period. This is extremely important when parts of the plant other than the leaves are to be sold. It is also important to notice the amount of carbon respired in the short photosynthetic period. The light period effect on carbohydrate fixation, dark respiration, and translocation is shown in this report.

  13. Donepezil Treatment of Older Adults with Cognitive Impairment and Depression (DOTCODE study): clinical rationale and design

    2014-01-01

    Treatment strategies for patients with depression and cognitive impairment (DEP-CI), who are at high risk to develop a clinical diagnosis of dementia, are not established. This issue is addressed in the donepezil treatment of cognitive impairment and depression (DOTCODE) pilot clinical trial. The DOTCODE study is the first long-term treatment trial that assesses differences in conversion to dementia and cognitive change in DEP-CI patients using a study design of open antidepressant medication plus add-on randomized, double-blind, placebo-controlled treatment with the acetylcholinesterase inhibitor donepezil. In Phase 1, DEP-CI patients receive optimized antidepressant treatment for 16 weeks. In Phase 2, antidepressant treatment is continued with the addition of randomized, double-blind treatment with donepezil or placebo. The total study duration for each patient is 78 weeks (18 months). Eighty DEP-CI outpatients (age 55 to 95 years) are recruited: 40 at New York State Psychiatric Institute/Columbia University and 40 at Duke University Medical Center. The primary outcome is conversion to a clinical diagnosis of dementia. The secondary outcomes are cognitive change scores in Selective Reminding Test (SRT) total recall and the modified Alzheimer’s Disease Assessment Scale (ADAS-cog). Other key assessments include the 24-item Hamilton Depression Rating Scale and antidepressant response; Clinical Global Impression (CGI) for depression, cognition, and global status; neuropsychological test battery for diagnosis; informant report of functional abilities (Pfeffer FAQ); Treatment Emergent Symptom Scale (TESS) for somatic side effects.

  15. A highly specific test for periodicity

    SciTech Connect

    Ansmann, Gerrit

    2015-11-15

    We present a method that allows to distinguish between nearly periodic and strictly periodic time series. To this purpose, we employ a conservative criterion for periodicity, namely, that the time series can be interpolated by a periodic function whose local extrema are also present in the time series. Our method is intended for the analysis of time series generated by deterministic time-continuous dynamical systems, where it can help telling periodic dynamics from chaotic or transient ones. We empirically investigate our method's performance and compare it to an approach based on marker events (or Poincaré sections). We demonstrate that our method is capable of detecting small deviations from periodicity and outperforms the marker-event-based approach in typical situations. Our method requires no adjustment of parameters to the individual time series, yields the period length with a precision that exceeds the sampling rate, and its runtime grows asymptotically linear with the length of the time series.

  16. Sawtooth period control by power modulation

    It is foreseen that long sawtooth oscillations will occur during ITER H-mode scenarios leading to confinement loss and even disruptions. Sawtooth period control is therefore crucial. Most sawtooth period control approaches depend on changing the deposition location of electron-cyclotron current drive (ECCD) near r(q =1). In contrast to this, several TCV and AUG experiments with fixed ECCD deposition location show that ECCD power modulation, either periodic or feedback controlled, can lead to fast and reliable period control. To understand this nonlinear phenomenon, a reduced and `hybrid' reset model has been derived that models the nonlinear dynamics. Analysis reveals that the sawtooth period can be controlled by power modulation, even in the case of significant model uncertainties or when there is a significant lengthening effect of the fast particles on the sawtooth period, as there will be in ITER. The model can also be used to design period control using ICRH influencing this fast particle effect.

  17. Long Periodic Terms in the Solar System

    NASA Technical Reports Server (NTRS)

    Bretagnon, P.

    1982-01-01

    The long period variations of the first eight planets in the solar system are studied. First, the Lagrangian solution is calculated and then the long period terms with fourth order eccentricities and inclinations are introduced into the perturbation function. A second approximation was made taking into account the short period terms' contribution, namely the perturbations of first order with respect to the masses. Special attention was paid to the determination of the integration constants. The relative importance of the different contributions is shown. It is useless, for example, to introduce the long period terms of fifth order if no account has been taken of the short period terms. Meanwhile, the terms that have been neglected would not introduce large changes in the integration constants. Even so, the calculation should be repeated with higher order short period terms and fifth order long periods.

  20. Does Treatment Readiness Enhance the Response of African American Substance Users to Motivational Enhancement Therapy?

    The development of effective treatments for African Americans and other ethnic minorities is essential for reducing health disparities in substance use. Despite research suggesting that Motivational Enhancement Therapy (MET) may reduce substance use among African Americans, the findings have been inconsistent. This research examined the extent to which readiness-to-change (RTC) affects response to MET among African American substance users. The study was a secondary analysis of the 194 African American substance users participating in a multisite randomized clinical trial evaluating MET originally conducted within the National Drug Abuse Treatment Clinical Trials Network. The participants were randomly assigned to receive either three sessions of MET or Counseling-As-Usual (CAU) followed by the ordinary treatment and other services offered at the five participating outpatient programs. Participants were categorized as either high or lower on RTC based on their scores on the University of Rhode Island Change Assessment. The participants reported their substance use at baseline and throughout the 16 weeks after randomization. Among the high RTC participants, those in MET tended to report fewer days of substance use per week over time than participants in CAU. However, among the lower RTC participants, the CAU group tended to report fewer days of substance use over time than MET participants. In contrast to previous thinking, the findings suggest that MET may be more effective for high than lower RTC African American participants. PMID:23421576

    Identifying neurobiological predictors of response to antipsychotics in patients with schizophrenia is a critical goal of translational psychiatry. Few studies, however, have investigated the relationship between indices of brain structure and treatment response in the context of a controlled clinical trial. In this study, we sought to identify magnetic resonance (MR) imaging measures of the brain that predict treatment response in patients experiencing a first-episode of schizophrenia. Structural MR imaging scans were acquired in 39 patients experiencing a first-episode of schizophrenia with minimal or no prior exposure to antipsychotics participating in a double-blind 16-week clinical trial comparing the efficacy of risperidone vs olanzapine. Twenty-five patients were classified as responders by meeting operationally defined treatment response criteria on 2 consecutive study visits. Fourteen patients never responded to antipsychotic medication at any point during the clinical trial. MR imaging scans were also acquired in 45 age- and sex-matched healthy volunteers. Cortical pattern matching methods were used to compare cortical thickness and asymmetry measures among groups. Statistical mapping results, confirmed by permutation testing, indicated that responders had greater cortical thickness in occipital regions and greater frontal cortical asymmetry compared with nonresponders. Moreover, among responders, greater thickness in temporal regions was associated with less time to respond. Our findings are consistent with the hypothesis that plasticity and cortical thickness may be more preserved in responders and that MR imaging may assist in the prediction of antipsychotic drug response in patients experiencing a first-episode of schizophrenia.

    Aims: The primary objective of this study was to analyze the association between alcohol consumption and short-term response to treatment (post intervention) in male patients with gambling disorder enrolled in a group cognitive behavioral therapy (CBT) program. Methods: The sample consisted of 111 male individuals with a diagnosis of Gambling Disorder, with a mean age of 45 years (SD = 12.2). All participants were evaluated by a comprehensive assessment battery and assigned to CBT groups of 10–14 patients attending 16 weekly outpatient sessions lasting 90 min each. Results: The highest mean pre- and post-therapy differences were recorded for the alcohol risk/dependence group on the obsessive/compulsive and anxiety dimensions of the SCL-90-R. As regards the presence of relapses and dropouts over the course of the CBT sessions, the results show a significant association with moderate effect size: patients with risk consumption or alcohol dependence were more likely to present poor treatment outcomes. Conclusions: Alcohol abuse was frequent in GD, especially in patients with low family income and high accumulated debts. High levels of somatization and high overall psychopathology (measured by the SCL-90-R) were associated with increased risk of alcohol abuse. Alcohol abuse was also associated with poor response to treatment. PMID:27065113

  3. [Treatment of recurrent furunculosis].

    PubMed

    Engelhard, Esther A N; Spanjaard, Lodewijk; Stijnis, C Kees

    2013-01-01

    The management of recurrent furunculosis is difficult, and often disappointing. We present the case of a 23-year-old female patient suffering from recurrent furunculosis. The furunculosis persisted after treatment with mupirocin nasal ointment, chlorhexidine soap and instructions for washing clothes, towels and bed sheets for a period of 7 days. Treatment with low-dose clindamycin for three months ultimately proved successful. We propose a structural approach for recurrent furunculosis in which extensive history-taking is followed by appropriate tests. Before prescribing an oral antibiotic (preferably low-dose clindamycin or a macrolide for 3 months), the patient should use an antimicrobial nasal ointment and soap and follow hygienic instructions as mentioned above. Members of the household who also have signs of the infection should be treated. Hygienic education is an essential component of treatment. We believe that this approach will lead to a treatment that is more effective and efficient. PMID:23369819

    2013-01-01

    Ganglion cysts are soft tissue swellings occurring most commonly in the hand or wrist. Apart from swelling, most cysts are asymptomatic. Other symptoms include pain, weakness, or paraesthesia. The two main concerns patients have are the cosmetic appearance of the cysts and the fear of future malignant growth. It has been shown that 58% of cysts will resolve spontaneously over time. Treatment can be either conservative or through surgical excision. This review concluded that nonsurgical treatment is largely ineffective in treating ganglion cysts. However, it advised to patients who do not surgical treatment but would like symptomatic relief. Compared to surgery, which has a lower recurrence rate but have a higher complication rate with longer recovery period. It has been shown that surgical interventions do not provide better symptomatic relief compared to conservative treatment. If symptomatic relief is the patient's primary concern, a conservative approach is preferred, whilst surgical intervention will decrease the likelihood of recurrence. PMID:24967120

    We compared 8 fortnightly sessions plus a self-care manual (guided self change, GSC) with 16 weekly individual sessions of cognitive behaviour therapy (CBT). There were 31 sufferers of DSM-III-R-bulimia nervosa (BN) in each group. Both treatments resulted in significant improvements regarding self and interviewer based measures of bulimia nervosa as well as depression, self-esteem, quality of life and knowledge about nutrition, weight and shape. There were no significant differences between therapies regarding drop-out rate, compliance with follow-up, and the number of patients receiving additional treatment. At none of the assessments was there a significant difference between GSC and CBT regarding severity of BN, Beck Depression Inventory-score, self-esteem, and quality of life. A significantly higher percentage of CBT-patients were abstinent from bingeing for at least one week at the end of treatment. Three months later, the GSC-group had caught up in this respect and knew more about nutition, weight and shape. Only the sum-scores on a BN self-rating scale were worse for GSC than CBT at the end of therapy and at follow-up. There were no significant differences between the two groups in general treatment satisfaction and judgement about the usefulness of the therapies. Thus, guided self change with a selfcare manual can save therapist time without impinging significantly on treatment satisfaction and effectiveness. PMID:9629559

  6. Probabilistic stellar rotation periods with Gaussian processes

    NASA Astrophysics Data System (ADS)

    Angus, Ruth; Aigrain, Suzanne; Foreman-Mackey, Daniel

    2015-08-01

    Stellar rotation has many applications in the field of exoplanets. High-precision photometry from space-based missions like Kepler and K2 allows us to measure stellar rotation periods directly from light curves. Stellar variability produced by rotation is usually not sinusoidal or perfectly periodic, therefore sine-fitting periodograms are not well suited to rotation period measurement. Autocorrelation functions are often used to extract periodic information from light curves, however uncertainties on rotation periods measured by autocorrelation are difficult to define. A ‘by eye’ check, or a set of heuristic criteria are used to validate measurements and rotation periods are only reported for stars that pass this vetting process. A probabilistic rotation period measurement method, with a suitable generative model bypasses the need for a validation stage and can produce realistic uncertainties. The physics driving the production of variability in stellar light curves is still poorly understood and difficult to model. We therefore use an effective model for stellar variability: a Gaussian process with a quasi-periodic covariance function. By injecting fake signals into Kepler light curves we show that the GP model is well suited to quasi-periodic, non-sinusoidal signals, is capable of modelling noise and physical signals simultaneously and provides probabilistic rotation period measurements with realistic uncertainties.

    Phononic crystal is now used to control acoustic waves. When the crystal goes to a larger scale, it is called periodic structure. The band gaps of the periodic structure can be reduced to range from 0.5 Hz to 50 Hz. Therefore, the periodic structure has potential applications in seismic wave reflection. In civil engineering, the periodic structure can be served as the foundation of upper structure. This type of foundation consisting of periodic structure is called periodic foundation. When the frequency of seismic waves falls into the band gaps of the periodic foundation, the seismic wave can be blocked. Field experiments of a scaled two dimensional (2D) periodic foundation with an upper structure were conducted to verify the band gap effects. Test results showed the 2D periodic foundation can effectively reduce the response of the upper structure for excitations with frequencies within the frequency band gaps. When the experimental and the finite element analysis results are compared, they agree well with each other, indicating that 2D periodic foundation is a feasible way of reducing seismic vibrations.

  6. The period distribution of cataclysmic variables

    NASA Astrophysics Data System (ADS)

    Hameury, J. M.; King, A. R.; Lasota, J. P.; Ritter, H.

    1988-04-01

    In a recent paper, Warner and Livio (1987) claim that the AM Her and SU UMa cataclysmic variables (CVs) with periods P less than 2 hr show a tendency to cluster in disjoint period ranges. It is shown here that the statistical significance of this result is entirely due to the large accumulation of AM Her systems in the range 113.5-114.8 minutes. It has been shown elsewhere that this period spike is probably caused by the resumption of mass transfer after the systems cross the 2-3 hr period gap. It is emphasized that the 'synchronization-induced gap' mechanism of Lamb and Melia (1987) is based on an incorrect assumption about the contraction time scale of a mass-losing secondary star and cannot produce any significant gap in the period distribution of AM Her systems or lead to the formation of ultrashort-period CVs, as claimed by Lamb and Melia.

    A generalization of that portion of the work of Berger, which deals with the long period coupling effect of certain pairs of zonal harmonics. Long period terms arising from the short short period coupling of zonal harmonics are derived for Lagrange's equations. The formulation is general so that the results are valid for any pairs of zonal harmonics. Formulas are given to generate the various functions and integrals needed for the results given. Checks have been made against the work of Kozai.

    Hemangiomas are the most common soft tissue tumors of infancy. Almost 60% of these tumors develop in the head and neck region. Nasal hemangiomas, distort human physiognomy and leave long lasting psychological sequelae. Conservative approach (intralesional corticosteroids, laser) may accelerate involution. Proponents of an early surgery suggest that aesthetic improvement during a critical period in child development can be achieved. Fourteen patients with nasal hemangioma were treated during 5-year period (2003-2007) with intralesional corticosteroids, lenticular excision, open rhinoplasty excision, and circular excision with "purse string suture". The first line of treatment for large nasal hemangiomas is intralesional corticosteroids. Excision is indicated for small hemangiomas, while subtotal excision is preferable for large nasal hemangiomas. Circular excision and "purse string suture" is appropriate for prominent hemangiomas with predominant deep component. In our opinion surgery with maximal care for nasal architecture is the treatment option for nasal hemangioma. PMID:19656579

    Periodic paralysis is a rare disorder that causes episodes of severe muscle weakness that can be confused with other diseases, including epilepsy or myasthenia gravis. Hyperkalemic and hypokalemic paralysis are included within these diseases, the latter being divided into periodic paralysis (familial, thyrotoxic or sporadic) and non-periodic paralysis. In this regard, we present a case of familial hypokalemic periodic paralysis in an eighteen year-old female who was diagnosed with epilepsy in childhood, as well as a subclinical hypothyroidism (for which she received replacement therapy) months ago. The diagnosis was made by the anamnesis and the confirmation of hypokalemia. PMID:24360869
