To study the active ingredients in liver protection from Erzhi Wan (AIEP) on acute hepatic injury induced by carbon tetrachloride (CCl4) in mice. Sixty Kunming mice were randomly divided into six groups: the normal group, the model group, bifendate group (150 mg x kg(-1)), high AIEP group (19.8 g x kg(-1)), middle AIEP group (13.2 g x kg(-1)) and low AIEP group (6.6 g x kg(-1)). The treatment groups were orally administered once per day for 7 d separately, whereas the normal and model groups were orally administered with saline. Except normal rats, all the other rats were injected intraperitoneally CCl4 20 mL x kg(-1) once. The rats were sacrificed 16 h after CCl4 administration. Serum and liver samples were collected for analysis. The acute hepatic injury model was prepared by CCl4 injected intraperitoneally. Then, the therapeutic effects of AIEP on the model were evaluated by the activity determination of serum alanine aminotransferase and aspirate aminotransferase (ALT and AST), superoxide dismutase (SOD) and the content of malondialdehyde (MDA) in liver,and the hepatic pathohistological changes following the treatment. The activities of ALT and AST and the MDA content in liver was significantly increased and the activity of SOD was largely inhibited in the animals of modeling group. Following the treatment with AIEP, ALT and AST activities and MDA content were significantly reduced and SOD activity was obviously increased in the mice of treatment group. Furthermore, AIEP could ameliorate the hepatic pathological changes. AIEP have protective effects on acute hepatic injury induced by CCL4 in mice, and are the effect of the liver protecting active sites.

Engaging persons with dementia in meaningful activities supports well-being; however, care staff are challenged to implement age- and ability-appropriate activities in a group setting. We compared a randomly assigned treatment group, who received horticultural therapy-based (HT-based) programming to a comparison group, who engaged in traditional activities (TA) programming, on engagement and affect. Horticultural therapy-based programming was implemented twice weekly at 4 treatment sites for 6 weeks, while regular TA were observed at comparison sites. Results revealed no differences between groups on affective domains. Levels of adaptive behavior differed between the groups, with the treatment group demonstrating higher levels of active, passive, and other engagement and the comparison group demonstrating higher levels of self-engagement. Our results highlight the value of HT-based programs and the importance of simultaneously capturing participants' affective and behavioral responses. Theoretical and practical considerations about the facilitation of and context in which the programming occurs are discussed.

Determined efficacies of benzoyl peroxide may be affected by study design, implementation, and vehicle effects. We sought to elucidate areas that may allow improvement in determining accurate treatment efficacies by determining rates of active treatment and vehicle responders in randomized controlled trials assessing the efficacy of topical benzoyl peroxide to treat acne. We conducted a systematic review of randomized vehicle-controlled trials evaluating the efficacy of topical benzoyl peroxide for the treatment of acne. We compared response rates of vehicle treatment arms versus those in benzoyl peroxide arms. Twelve trials met inclusion criteria with 2818 patients receiving benzoyl peroxide monotherapy treatment and 2004 receiving vehicle treatment. The average percent reduction in total number of acne lesions was 44.3 (SD = 9.2) and 27.8 (SD = 21.0) for the active and vehicle treatment groups, respectively. The average reduction in non-inflammatory lesions was 41.5 % (SD = 9.4) in the active treatment group and 27.0 % (SD = 20.9) in the vehicle group. The average percent decrease in inflammatory lesions was 52.1 (SD = 10.4) in the benzoyl peroxide group and 34.7 (SD = 22.7) in the vehicle group. The average percentage of participants achieving success per designated study outcomes was 28.6 (SD = 17.3) and 15.2 (SD = 9.5) in the active treatment and vehicle groups, respectively. Patient responses in randomized controlled trials evaluating topical acne therapies may be affected by clinical trial design, implementation, the biologic effects of vehicles, and natural disease progression. "No treatment" groups may facilitate determination of accurate treatment efficacies.

The aim of this study was to compare the effects of inorganic and organic selenium compounds supplementations to diets containing adequate selenium in broilers on performance, carcass traits, plasma and tissue glutathione peroxidase activity. A total of 150 one-day-old broilers were randomized into one control and two treatment groups each containing 50 birds; each group was then divided into 3 replicate groups. The experiment lasted 42 days. All groups were fed with broiler starter diet from day 1 to 21 and finisher diet from day 22 to 42. The basal diet for control group included adequate selenium due to vitamin-mineral premix and feeds. The basal diet was supplemented with 0.2 mg/kg organic selenium (selenomethionine, treatment group 1) and 0.2 mg/kg inorganic selenium (sodium selenite, treatment group 2). Although no significant differences were determined between treatment group 1 and the control group for mean body weights, the differences between the group given inorganic selenium and the other groups were statistically significant (p < 0.01). There was no significant difference between control and treatment groups with regard to mean feed intake and feed efficiency. The dressing percentages of the second treatment group were found to be lower than the first treatment group. Treatment groups were observed to have increased levels of glutathione peroxidase in plasma (p <0.01), kidney (p < 0.05), femoral muscle (p < 0.05), heart (p < 0.01) and liver tissue (p < 0.01) compared with the control group. Results of this study indicated that the supplementation of organic selenium to diets containing adequate selenium increased plasma, liver, femoral muscle, kidney and heart tissue glutathione peroxidase activity in broilers.

Purpose This study examines the absolute and relative effects of three different treatment programs for school-aged bilingual children with primary or specific language impairment (PLI). It serves to expand the evidence base on which service providers can base treatment decisions. It also explores hypothesized relations between languages and cognition in bilinguals with PLI. Method Fifty-nine school-aged Spanish-English bilingual children with PLI were assigned to receive nonlinguistic cognitive processing, English, bilingual (Spanish-English), or deferred treatment. Participants in each of the three active treatments received treatment administered by nationally certified speech-language pathologists. Pre- and post-treatment assessments measured change in nonlinguistic cognitive processing, English, and Spanish skills, and analyses examined change within and across both treatment groups and skill domains. Results All active treatment groups made significant pre- to post-treatment improvement on multiple outcome measures. There were fewer significant changes in Spanish than in English across groups. Between group comparisons indicate that the active treatment groups generally outperformed the deferred treatment control, reaching statistical significance for two tasks. Conclusions Results provide insight into cross-language transfer in bilingual children and advance understanding of the general PLI profile with respect to relationships between basic cognitive processing and higher level language skills.

To comparatively and prospectively compare in a randomized clinical trial, dentin hypersensitivity after treatment with three in-office bleaching systems, based on hydrogen peroxide at different concentrations, with and without light source activation. 88 individuals were included according to inclusion and exclusion criteria. Subjects were randomly divided into the following three treatment groups: Group 1 was treated with three 15-minute applications of hydrogen peroxide at 15% with titanium dioxide (Lase Peroxide Lite) that was light-activated (Light Plus Whitening Lase) with five cycles of 1 minute and 30 seconds each cycle, giving a total treatment time of 45 minutes; Group 2 was treated with three 10-minute applications of hydrogen peroxide at 35% (Lase Peroxide Sensy), activated by light (LPWL) same activation cycles than Group 1, with a total treatment time of 30 minutes; Group 3 was treated with only one application for 45 minutes of hydrogen peroxide at 35% (Whitegold Office) without light activation. Each subject underwent one session of bleaching on the anterior teeth according to the manufacturers' instructions. Dentin sensitivity was recorded with a visual analogue scale (VAS) at baseline, immediately after, and at 7 and 30 days after treatment using a stimulus of an evaporative blowing triple syringe for 3 seconds on the upper central incisors from a distance of 1 cm. A Kruskal-Wallis test followed by Mann-Whitney test was performed for statistical analysis. All groups showed increased sensitivity immediately after treatment. Group 1 displayed less changes relative to baseline with no significant differences (P = 0.104). At 7 and 30 days after treatment, a comparison of VAS values indicated no significant differences between all groups (P = 0.598 and 0.489, respectively).

The Pervasive Problem With Placebos in Psychology: Why Active Control Groups Are Not Sufficient to Rule Out Placebo Effects.

To draw causal conclusions about the efficacy of a psychological intervention, researchers must compare the treatment condition with a control group that accounts for improvements caused by factors other than the treatment. Using an active control helps to control for the possibility that improvement by the experimental group resulted from a placebo effect. Although active control groups are superior to "no-contact" controls, only when the active control group has the same expectation of improvement as the experimental group can we attribute differential improvements to the potency of the treatment. Despite the need to match expectations between treatment and control groups, almost no psychological interventions do so. This failure to control for expectations is not a minor omission-it is a fundamental design flaw that potentially undermines any causal inference. We illustrate these principles with a detailed example from the video-game-training literature showing how the use of an active control group does not eliminate expectation differences. The problem permeates other interventions as well, including those targeting mental health, cognition, and educational achievement. Fortunately, measuring expectations and adopting alternative experimental designs makes it possible to control for placebo effects, thereby increasing confidence in the causal efficacy of psychological interventions. © The Author(s) 2013.

Reactive oxygen species (ROS) play a major role in myocardial damage during acute myocardial infarction (AMI). This study aimed to determine the antioxidant and antiapoptotic activities of an ethanolic extract from Ulva lactuca L. (EEUL) against AMI. Thirty-six male Wistar rats were divided into six groups: one control group and five treatment groups. Treatment group II was given 85 mg/kg body weight (BW) of isoproterenol (ISO). Group III, IV and V were given ISO and EEUL at 250, 500 and 750 mg/kg BW, respectively. Group VI were given 10 mg/kg BW of ISO and melatonin. EEUL and melatonin were orally administered for 28 days. ISO was injected subcutaneously on day 29 and 30 to chemically induce AMI. On day 31, blood was collected for antioxidant assay and heart tissues were collected for histological examination. The activity of catalase (CAT), an endogenous antioxidant, in the EEUL-treatment groups was significantly increased compared to the ISO-treatment group ( P < 0.001). The EEUL-treatment groups showed significantly decreased expression of caspase-3 ( P < 0.001) and better myocardial tissue morphology. EEUL possibly protects against AMI because of its antioxidant and antiapoptotic properties.

This is an open uncontrolled study about effects of physical treatment on disease activity parameters of patients with rheumatoid arthritis and psoriatic arthritis. The aim of the study was to establish if there was any improvement of disease activity parameters after four weeks of physical and spa treatment. We compared morning stiffness, tender and swollen joint count, body pain level and Disease Activity Score 28 (DAS-28) in patients with rheumatoid and psoriatic arthritis, and assessed the effect of physical and spa treatment on those parameters. The research encompassed 109 patients: 69 with rheumatoid arthritis (RA group) and 40 with psoriatic arthritis (PA group). They were from Norway, staying for four weeks in June-September 2003. The groups served as their own controls--"one group pre-test post test" study. Disease activity measurement was made twice: at the beginning and at the end of treatment. The therapeutic set consisted of mud applications, kinesitherapy, mineral water pool and electrotherapy. At the beginning there was no significant difference in observed disease activity parameters between patients with rheumatoid and psoriatic arthritis (p > 0.05). After four weeks of physical and spa treatment disease activity was significantly reduced in all observed parameters in both groups: morning stiffness (p < 0.001 RA + PA), tender joint count (p < 0.01 RA + PA), swollen joint count (p < 0.01 RA; p < 0.05 PA), body pain (p < 0.01 RA + PA) and DAS-28 score (p < 0.01 RA+PA). Physical and spa treatment, together with climatic factors in Igalo, lead to a significant reduction of disease activity parameters of patients suffering from rheumatoid arthritis and psoriatic arthritis.

Abstract This double-blind, sham-controlled study sought to investigate the effectiveness of cranial electrotherapy stimulation (CES) for the treatment of bipolar II depression (BD II). After randomization, the active group participants (n = 7) received 2 mA CES treatment for 20 minutes five days a week for 2 weeks, whereas the sham group (n = 9) had the CES device turned on and off. Symptom non-remitters from both groups received an additional 2 weeks of open-label active treatment. Active CES treatment but not sham treatment was associated with a significant decrease in the Beck Depression Inventory (BDI) scores from baseline to the second week (p = 0.003) maintaining significance until week 4 (p = 0.002). There was no difference between the groups in side effects frequency. The results of this small study indicate that CES may be a safe and effective treatment for BD II suggesting that further studies on safety and efficacy of CES may be warranted. PMID:26414234

To evaluate the health-related quality of life effects of muscle stretching, manual therapy and steroid injections in addition to 'stay active' care in acute or subacute low back pain patients. A randomized, controlled trial during 10 weeks with four treatment groups. Nine primary health care and one outpatient orthopaedic hospital department. One hundred and sixty patients with acute or subacute low back pain. Ten weeks of 'stay active' care only (group 1), or 'stay active' and muscle stretching (group 2), or 'stay active', muscle stretching and manual therapy (group 3), or 'stay active', muscle stretching, manual therapy and steroid injections (group 4). The Gothenburg Quality of Life instrument subscales Well-being score and Complaint score. In a multivariate analysis adjusted for possible outcome affecting variables other than the treatment given Well-being score was 68.4 (12.5), 72.1 (12.4), 72,3 (12.4) and 72.7 (12.5) in groups 1-4, respectively (P for trend <0.05). There were significant trends for the well-being components patience (P < 0.005), energy (P < 0.05), mood (P < 0.05) and family situation (P < 0.05). The remaining two components and Complaint score showed a non-significant trend towards improvement. The effects on health-related quality of life were greater the larger the number of treatment modalities available. The 'stay active' treatment group, with the most restricted number of modalities, had the most modest health-related quality of life improvement, while group 4 with the most generous choice of treatment modalities, had the greatest improvement.

Study Objective: To investigate the effectiveness of intensive sleep retraining in comparison and combination with traditional behavioral intervention for chronic primary insomnia. Participants: Seventy-nine volunteers with chronic sleep-onset insomnia (with or without sleep maintenance difficulties) were randomly assigned either to intensive sleep retraining (ISR), stimulus control therapy (SCT), ISR plus SCT, or the control (sleep hygiene) treatment condition. Intervention: ISR treatment consisted of 50 sleep onset trials over a 25-h sleep deprivation period. Measurements and Results: Treatment response was assessed with sleep diary, activity monitoring, and questionnaire measures. The active treatment groups (ISR, SCT, ISR+SCT) all resulted in significant improvements in sleep onset latency and sleep efficiency, with moderate to large effect sizes from pre- to post-treatment. Wake time after sleep onset decreased significantly in the SCT and ISR+SCT groups. Total sleep time increased significantly in the ISR and ISR+SCT treatment groups. Participants receiving ISR (ISR, ISR+SCT) experienced rapidly improved SOL and TST during treatment, suggesting an advantage of rapid improvements in sleep in response to ISR. Although there were few statistically significant differences between groups on individual variables, ISR+SCT resulted in consistently larger effect sizes of change than other treatments, including questionnaire measures of sleep quality, sleep self-efficacy, and daytime functioning. The combination treatment group (ISR+SCT) showed trends to outperform other active treatment groups with fewer treatment dropouts, and a greater proportion of treatment responders with 61% reaching “good sleeper” status. Treatment gains achieved at post-treatment in the active treatment groups were largely maintained throughout follow-up periods to 6 months. Conclusion: This 25-hour intensive conditioning treatment for chronic insomnia can produce rapid improvements in sleep, daytime functioning, and psychological variables. Adding ISR to traditional interventions seems to result in a superior treatment response. Citation: Harris J; Lack L; Kemp K; Wright H; Bootzin R.

The aim of this study was to determine the erythrocyte antioxidant enzyme activity and the superoxide dismutase, catalase, glutathione peroxidase, and plasma malondialdehyde levels in aging mice and to evaluate how these measures are modulated by potential antioxidants, including the tocotrienol-rich fraction, Piper betle, and Chlorella vulgaris. One hundred and twenty male C57BL/6 inbred mice were divided into three age groups: young (6 months old), middle-aged (12 months old), and old (18 months old). Each age group consisted of two control groups (distilled water and olive oil) and three treatment groups: Piper betle (50 mg/kg body weight), tocotrienol-rich fraction (30 mg/kg), and Chlorella vulgaris (50 mg/kg). The duration of treatment for all three age groups was two months. Blood was withdrawn from the orbital sinus to determine the antioxidant enzyme activity and the malondialdehyde level. Piper betle increased the activities of catalase, glutathione peroxidase, and superoxide dismutase in the young, middle, and old age groups, respectively, when compared to control. The tocotrienol-rich fraction decreased the superoxide dismutase activity in the middle and the old age groups but had no effect on catalase or glutathione peroxidase activity for all age groups. Chlorella vulgaris had no effect on superoxide dismutase activity for all age groups but increased glutathione peroxidase and decreased catalase activity in the middle and the young age groups, respectively. Chlorella vulgaris reduced lipid peroxidation (malondialdehyde levels) in all age groups, but no significant changes were observed with the tocotrienol-rich fraction and the Piper betle treatments. We found equivocal age-related changes in erythrocyte antioxidant enzyme activity when mice were treated with Piper betle, the tocotrienol-rich fraction, and Chlorella vulgaris. However, Piper betle treatment showed increased antioxidant enzymes activity during aging.

The activity of garenoxacin was compared to that of levofloxacin or penicillin in a rabbit model of Streptococcus mitis group (penicillin MIC, 0.125 microg/ml) and Streptococcus sanguinis group (penicillin MIC, 0.25 microg/ml) endocarditis. Garenoxacin and levofloxacin had MICs of 0.125 and 0.5 microg/ml, respectively, for both study isolates. Rabbits with catheter-induced aortic valve endocarditis were given no treatment, penicillin at 1.2x10(6) IU/8 h intramuscularly, garenoxacin at 20 mg/kg of body weight/12 h intravenously, or levofloxacin at 40 mg/kg/12 h intravenously. For both isolates tested, garenoxacin area under the curve (AUC)/MIC and maximum concentration of drug in serum (Cmax)/MIC ratios were 368 and 91, respectively. Rabbits were sacrificed after 3 days of treatment; cardiac valve vegetations were aseptically removed and quantitatively cultured. For S. mitis group experimental endocarditis, all studied antimicrobial agents were more active than no treatment (P<0.001), whereas for S. sanguinis group endocarditis, no studied antimicrobial agents were more active than no treatment. We conclude that AUC/MIC and Cmax/MIC ratios may not predict activity of some quinolones in experimental viridans group endocarditis and that garenoxacin and levofloxacin may not be ideal choices for serious infections caused by some quinolone-susceptible viridans group streptococci.

Background and aims No effective pharmacotherapy for methamphetamine (MA) use disorder has yet been found. This study evaluated sustained-release methylphenidate (MPH-SR) compared with placebo (PLA) for treatment of MA use disorder in people also undergoing behavioural support and motivational incentives. Design This was a randomized, double-blind, placebo-controlled design with MPH-SR or PLA provided for 10 weeks (active phase) followed by 4 weeks of single-blind PLA. Twice-weekly clinic visits, weekly group counseling (CBT), and motivational incentives (MI) for MA-negative urine drug screens (UDS) were included. Setting Treatment sites were in Los Angeles, California (LA) and Honolulu, Hawaii (HH), USA. Participants 110 MA-dependent (via DSM-IV) participants (LA = 90; HH = 20). Measurements The primary outcome measure is self-reported days of MA use during the last 30 days of the active phase. Included in the current analyses are drug use (UDS and self-report), retention, craving, compliance (dosing, CBT, MI), adverse events, and treatment satisfaction. Findings No difference was found between treatment groups in self-reported days of MA use during the last 30 days of the active phase (p=0.22). In planned secondary outcomes analyses, however, the MPH group had fewer self-reported MA use days from baseline through the active phase compared with the PLA group (p=0.05). The MPH group also had lower craving scores and fewer marijuana-positive UDS than the PLA group in the last 30 days of the active phase. The two groups had similar retention, other drug use, adverse events, and treatment satisfaction. Conclusions Methylphenidate may lead to a reduction in concurrent methamphetamine use when provided as treatment for patients undergoing behavioural support for moderate to severe methamphetamine use disorder but this requires confirmation.

To investigate the effect of the water soluble fraction of crude oil (WSF) on marine bivalves, the scallop Chlamys farreri was exposed to three WSF concentrations (0.18 mg/L, 0.32 mg/L, and 0.51 mg/L, respectively) in seawater. Petroleum hydrocarbon contents in scallops and a suite of enzymes [7-Ethoxyresorufin-O-deethylase (EROD), aryl hydrocarbon hydroxylase (AHH), glutathione S-transferase (GST), and glutathione peroxidase (GPx)] in gills and digestive glands were monitored over 10 days. The results revealed that WSF affected the activity of the four enzymes in the gills and digestive glands. EROD activity in the gills was significantly induced in most individuals of the three test groups, while in the digestive gland it was significantly induced in the low-concentration group within 4 days but was inhibited in the middle- and high-concentration groups on days 1, 4, and 10. AHH activity in the gills of all treatment groups was significantly induced on day 1. In the digestive gland, AHH activity was induced in most individuals from the treatment groups. In all treatment groups, GST activity was significantly inhibited from days 2 to 10 in the gills and was induced after day 4 in the digestive gland. GPx activity in the gills was significantly inhibited throughout the exposure period in all treatment groups. There was no overall significant difference in GPx activity in the digestive gland between the control and treatment groups. Our results also revealed that petroleum hydrocarbon concentrations in the tissues increased linearly with exposure time. EROD activity in the digestive gland and GST and GPx activity in the gill tissue were negatively correlated with petroleum hydrocarbon body burden. These enzymes play important roles in detoxification and can act as potential biomarkers for monitoring petroleum hydrocarbon contaminants in the marine environment.

Patients of the control group were treated by manual acupuncture stimulation of main acupoints Jiaji (EX-B 2), Huantiao (GB 30, affected side), Chengshan (BL 57, affected side), Kunlun (BL 60, affected side), and supplemented acupoints Yanglingquan (GB 34), Weizhong (BL 40) and Zusanli (ST 36) in combination with wheat-flour-cake separated moxibustion at the main acupoints, and patients of the treatment group were treated by medicinal-cake [Chuanwu (Radix Aconiti), Caowu (Radix Aconiti Kusnezoffii), Ruxiang (Olibanum), etc. ]-separated moxibustion in combination with manual acupuncture stimulation of the same acupoints mentioned above. Acupuncture treatment was conducted for 30 min, followed by moxibustion for 15 min. The treatment was given once daily for 10 days. The patients' back-leg functional activity ability was assessed using straight-leg raising test, and the pain state assessed using visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) scores, respectively. The therapeutic effect was evaluated by using "Crite- ria for Diagnosis and Outcome Evaluation of Clinical Disorders or Syndromes of Chinese Medicine" issued in 1994 and plasma SP content was detected by radioimmunoassay. After the therapy, the back-leg activity score and JOA score of both groups were significantly higher than those of pre-treatment in the same one group (P<0. 05, P<0. 01), and those of the treatment group were significantly higher than those of the control group (P<0.05). The VAS score of the treatment group was re- markably lower than that of the control group (P<0. 01). After the treatment, the plasma SP content was markedly lower in the treatment group than in the control group (.P<0O. 05 ) . Medicinal-cake-separated moxibustion therapy can ame- liorate pain severity and functional activity of the back-leg pain patients with lumbar disc hernia, which may be related to its effect in reducing blood SP level.

This study investigated the effect of active-learning strategies on college students' achievement, motivation, and self-efficacy in a human physiology course for nonmajors. Variables were studied via a quasi-experimental, Solomon four-group design on 141 students at a small west-Texas university. Treatment groups were taught using a continuum-based, active-learning model implemented over the course of a semester. Control groups were taught using traditional didactic lecture methods. To assess the effects of the continuum-based active learning strategies, students were administered a comprehensive physiology content exam, the Motivated Strategies for Learning Questionnaire, and attitude surveys. Factorial analyses indicated that the treatment groups acquired significantly more content knowledge and were significantly more self-efficacious than students in the control groups. There were no significant differences in motivation. Attitude surveys indicated that students in both the treatment and control groups demonstrated a positive attitude toward active learning, believed it helped (or would help) them to learn the material, and would choose an active learning course in the future.

Many people living at high altitudes experiencing a condition called intermittent hypobaric hypoxia (IHH). Some people even create IHH condition as an exercise for pilots, athletes, and mountaineers. In this experiment, we aimed to determine whether the protective effect of IHH is mediated through glutathione peroxidase (GPX) enzyme. The experiment’s sample is two-month-old healthy Sprague-Dawley rat kidneys weighing 200-250 g. Intermittent hypobaric hypoxia treatment is done using a Hypobaric Chamber type I that can mimic air pressure at certain altitudes: 35,000 (one minute), 30,000 (three minutes), 25,000 (five minutes), and 18,000 (30 minutes) feet. The rats were divided into five treatment groups, including a control group, hypobaric-hypoxia group, and intermittent hypobaric-hypoxia 1x, 2x, and 3x groups with each group consisting of three rats. The specific activity of GPX was measured using RANDOX and RANSEL methods. The statistical analysis of one way-ANOVA did not show significant differences between the groups (p > 0.05), although specific activities of the renal GPX of rats exposed to hypobaric-hypoxia were higher than the control group. This may be caused by the other antioxidants’ activities. In conclusion, the IHH treatment did not affect GPX activity in the rat kidneys.

We evaluated patients' perception and satisfaction with nonsurgical pulsed magnetic stimulation (PMS) for treatment of female stress urinary incontinence (SUI) in a randomized, double-blind, sham-controlled trial. Women with SUI (n = 120) were randomized to either active or sham PMS for 8 weeks (twice/week). Patients answered seven questions on their perception and acceptability, each measured on a 5-point Likert scale. Treatment satisfaction was assessed using two parameters: (i) the single-item question "Overall, please rate how satisfied you are with the treatment" and (ii) Patient Global Impression of Improvement (PGI-I). All adverse events were documented. A total of 115 patients completed treatments (active: n = 57, sham: n = 58). There were no significant differences between groups in all parameters regarding perception and acceptability (p > 0.05). In terms of treatment satisfaction, a significantly higher proportion of patients in the active group (n = 47/57, 82.4%) were either mostly or completely satisfied compared with those in the sham group (n = 27/58, 46.6%) ((p = 0.001). Similarly, a statistically significantly higher percentage of patients in the active group (n = 39/57, 68.4%) felt much or very much better compared with patients in the sham group (n = 11/58, 19.0%) as measured using the PGI-I (p < 0.001). Three (5.3%) patients in the active group and five (8.6%) in the sham group experienced adverse events (p = 0.72). Regardless of treatment arms, 109 (94.8%) patients would not consider surgical options even if they required further treatment for their condition. PMS was well accepted, well tolerated, and resulted in a high treatment satisfaction among women with SUI.

Modeling optimal treatment strategies in a heterogeneous mixing model.

Many mathematical models assume random or homogeneous mixing for various infectious diseases. Homogeneous mixing can be generalized to mathematical models with multi-patches or age structure by incorporating contact matrices to capture the dynamics of the heterogeneously mixing populations. Contact or mixing patterns are difficult to measure in many infectious diseases including influenza. Mixing patterns are considered to be one of the critical factors for infectious disease modeling. A two-group influenza model is considered to evaluate the impact of heterogeneous mixing on the influenza transmission dynamics. Heterogeneous mixing between two groups with two different activity levels includes proportionate mixing, preferred mixing and like-with-like mixing. Furthermore, the optimal control problem is formulated in this two-group influenza model to identify the group-specific optimal treatment strategies at a minimal cost. We investigate group-specific optimal treatment strategies under various mixing scenarios. The characteristics of the two-group influenza dynamics have been investigated in terms of the basic reproduction number and the final epidemic size under various mixing scenarios. As the mixing patterns become proportionate mixing, the basic reproduction number becomes smaller; however, the final epidemic size becomes larger. This is due to the fact that the number of infected people increases only slightly in the higher activity level group, while the number of infected people increases more significantly in the lower activity level group. Our results indicate that more intensive treatment of both groups at the early stage is the most effective treatment regardless of the mixing scenario. However, proportionate mixing requires more treated cases for all combinations of different group activity levels and group population sizes. Mixing patterns can play a critical role in the effectiveness of optimal treatments. As the mixing becomes more like-with-like mixing, treating the higher activity group in the population is almost as effective as treating the entire populations since it reduces the number of disease cases effectively but only requires similar treatments. The gain becomes more pronounced as the basic reproduction number increases. This can be a critical issue which must be considered for future pandemic influenza interventions, especially when there are limited resources available.

A randomized pilot trial evaluated the hypothesis that early intervention lessens sexual dysfunction in the first year on aromatase inhibitors. A secondary aim was comparing the efficacy of two vaginal moisturizers. Fifty-seven postmenopausal women with early stage breast cancer starting aromatase inhibitors were randomized to three treatment groups. All received a handout on managing sexual and other side effects. The Usual Care group received no additional therapy. The Active Treatment groups received a 6-month supply of a vaginal moisturizer (hyaluronic acid-based in Active Group-H and prebiotic in Active Group-P) and a vaginal lubricant and dilator, plus access to an educational website and phone coaching. Questionnaires completed at baseline, 6, and 12 months included the Female Sexual Function Index (FSFI), Menopausal Sexual Interest Questionnaire (MSIQ), Female Sexual Distress Scale-Revised (FSDS-R), and a menopausal symptom scale. Forty-nine women (86%) provided follow-up data. Mean age was 59 and 77% were non-Hispanic Caucasian. Sexual function was impaired at baseline, but remained stable over 12 months for all groups. The combined active treatment group had less dyspareunia (P = 0.07) and sexual distress (P = 0.02) at 6 months than the Usual Care group. At 6 months, the Active-H group improved significantly more than the Active-P group on FSFI total score (P = 0.04). Sexual counseling helped women maintain stable sexual function on aromatase inhibitors. Active intervention resulted in better outcomes at 6 months. This promising pilot trial suggests a need for more research on preventive counseling to maintain sexual function during aromatase inhibitor treatment.

Treatment of traumatised refugees is one of the fields within psychiatry, which has received little scientific attention. Evidence based treatment and knowledge on the efficiency of the treatment for this complex patient group is therefore scarce. This leads to uncertainty as to which treatment should be offered and potentially lowers the quality of life for the patients. Chronic pain is very common among traumatised refugees and it is believed to maintain the mental symptoms of trauma. Hence, treating chronic pain is believed to be of high clinical value for this patient group. In clinical studies, physical activity has shown a positive effect on psychiatric illnesses such as depression and anxiety and for patients with chronic pain. However, scientific knowledge about physical activity as part of the treatment for traumatised refugees is very limited and no guidelines exist on this topic. This study will include approximately 310 patients, randomised into three groups. All three groups receive psychiatric treatment as usual for the duration of 6-7 months, consisting of consultations with a medical doctor including pharmacological treatment and manual-based Cognitive Behavioural Therapy. The first group only receives treatment as usual while the second and the third groups receive either Basic-Body Awareness Therapy or mixed physical activity as add-on treatments. Each physical activity is provided for an individual 1-hour consultation per week, for the duration of 20 weeks. The study is being conducted at the Competence Centre for Transcultural Psychiatry, Mental Health Centre Ballerup in the Capital Region of Denmark. The primary endpoint of the study is symptoms of Post Traumatic Stress Disorder; the secondary endpoints are depression and anxiety as well as quality of life, functional capacity, coping with pain, body awareness and physical fitness. This study will examine the effect of physical activity for traumatised refugees. This has not yet been done in a randomised controlled setting on such a large scale before. Hereby the study will contribute to important knowledge that is expected to be used in future clinical guidelines and reference programs. ClinicalTrials.gov NCT01955538 .

Hypertension is present in some hyperthyroid cats at diagnosis or can develop after treatment for hyperthyroidism. Activation of the renin-angiotensin-aldosterone system (RAAS) could be involved in the pathogenesis of hypertension. Hyperthyroid cats that develop hypertension before or after treatment for hyperthyroidism will have greater RAAS activation than normotensive cats. Ninety-nine hyperthyroid cats. Retrospective case-control study. Plasma renin activity (PRA) and plasma aldosterone concentration (PAC) were measured in untreated hyperthyroid hypertensive cats (HT-Pre group), initially normotensive hyperthyroid cats that develop hypertension after treatment (HT-Post group), and hyperthyroid cats that are normotensive (NT group). Data are presented as median [25th, 75th percentile]. Baseline PRA was not significantly different among the 3 groups (HT-Pre group 1.50 [0.05, 2.37] ng/mL/h, HT-Post group 0.66 [0.17, 2.31] ng/mL/h, NT group 1.11 [0.57, 2.18] ng/mL/h; P = .44). PRA decreased significantly after treatment in the NT group (1.09 [0.53, 2.47] versus 0.22 [0.05, 0.76] ng/mL/h; P < .001) and the HT-Post group (0.71 [0.17, 2.33] versus 0.28 [0.07, 0.57] ng/mL/h; P = .006). Baseline PAC was not significantly different among the 3 groups (HT-Pre group 72.2 [40.0, 145.6] pg/mL, HT-Post group 69.7 [43.3, 142.6] pg/mL, NT group 109.0 [68.2, 184.6] pg/mL; P = .10). PAC decreased significantly after treatment in the NT group (114.4 [56.6, 204.1] versus 59.5 [32.4, 98.2] pg/mL; P < .001) but did not change significantly in the HT-Post group (61.2 [44.9, 124.0] versus 58.4 [42.0, 97.7] pg/mL; P = .59). RAAS activation occurs in hyperthyroid cats, but is not associated with the development of hypertension. PAC is not influenced by changes in PRA in hyperthyroid cats that develop hypertension after treatment, perhaps indicating RAAS dysfunction in these cats.

To study the effect of Acanthopanax senticosus injection (ASI) on the activities of human tumor necrosis factor (TNF) and natural killer cell (NKC) in the patients with lung cancer and the underlying mechanism. 73 cases with lung cancer were randomly divided into two groups, namely, the treatment group (n = 39) and observation group (n = 34); 61 cases with or without other diseases were respectively divided into control A (n = 30) and B (n = 31) groups. The patients in treatment group were injected with ASI for 21 days. The activities of human TNF and NKC and the levels of IgG, IgA and IgM were detected respectively. After injection with ASI the activity of TNF-alpha in treatment group was comparable with that in the two control groups and was significant lower that that in observation group. The activity of TNF-beta and the levels of IgA, IgG and IgM were significantly higher than those in observation group and two control groups (P < 0.01). The activity of NKC was also remarkably higher than observation and two control groups. ASI can regulate the cellular immunity and factor, indicating that ASI can be used as an assistant drug to regulate the function of cellular immunity in the patients with lung cancer.

Objectives. To evaluate whether combining mental practice with physical practice training enhances hand function in patients with stroke. Methods. 10 for treatment and 10 for control were recruited for this pre/posttraining matched case control study. In the treatment group, subjects underwent combining mental practice with physical practice for four weeks. In the control group, subjects only participated in physical practice. Change of hand function and the number of activated voxels of the contralateral somatosensory motor cortex (SMC) acquired by functional magnetic resonance imaging were measured. Results. After training, the Action Research Arm Test score increased by 12.65 for treatment and by 5.20 for control. There was a significant difference in the Action Research Arm Test score between the two groups (P = 0.04). The activated voxels number of the contralateral SMC increased in both groups, but the activated voxels number in the contralateral SMC and the improvement of hand function for treatment were greater than for control. In the treatment group, the number of activated voxels of the contralateral SMC was positively correlated with better hand function scores. Conclusions. Combining mental practice with physical practice may be a more effective treatment strategy than physical training alone for hand recovery in stroke patients. PMID:25435713

To compare the effects of candesartan cilexetil and enalapril maleate on right ventricular myocardial remodeling in dogs with experimentally induced pulmonary stenosis. 24 Beagles. 18 dogs underwent pulmonary arterial banding (PAB) to induce right ventricular pressure overload, and 6 healthy dogs underwent sham operations (thoracotomy only [sham-operated group]). Dogs that underwent PAB were allocated to receive 1 of 3 treatments (6 dogs/group): candesartan (1 mg/kg, PO, q 24 h [PABC group]), enalapril (0.5 mg/kg, PO, q 24 h [PABE group]), or no treatment (PABNT group). Administration of treatments was commenced the day prior to surgery; control dogs received no cardiac medications. Sixty days after surgery, right ventricular wall thickness was assessed echocardiographically and plasma renin activity, angiotensin-converting enzyme activity, and angiotensin I and II concentrations were assessed; all dogs were euthanatized, and collagenous fiber area, cardiomyocyte diameter, and tissue angiotensin-converting enzyme and chymase-like activities in the right ventricle were evaluated. After 60 days of treatment, right ventricular wall thickness, cardiomyocyte diameter, and collagenous fiber area in the PABNT and PABE groups were significantly increased, compared with values in the PABC and sham-operated groups. Chymase-like activity was markedly greater in the PABE group than in other groups. Results indicated that treatment with candesartan but not enalapril effectively prevented myocardial remodeling in dogs with experimentally induced subacute right ventricular pressure overload.

Cannabis is among the most frequently abused substances in the United States. Cognitive control is a contributory factor in the maintenance of substance-use disorders and may relate to treatment response. Therefore, we assessed whether cognitive-control-related neural activity before treatment differs between treatment-seeking cannabis-dependent and healthy individuals and relates to cannabis-abstinence measures during treatment and 1-year follow-up. Cannabis-dependent males (N=20) completed a functional magnetic resonance imaging (fMRI) cognitive-control (Stroop) task before a 12-week randomized controlled trial of cognitive–behavioral therapy and/or contingency management. A healthy-comparison group (N=20) also completed the fMRI task. Cannabis use was assessed by urine toxicology and self-report during treatment, and by self-report across a 1-year follow-up period (N=18). The cannabis-dependent group displayed diminished Stroop-related neural activity relative to the healthy-comparison group in multiple regions, including those strongly implicated in cognitive-control and addiction-related processes (eg, dorsolateral prefrontal cortex and ventral striatum). The groups did not differ significantly in response times (cannabis-dependent, N=12; healthy-comparison, N=14). Within the cannabis-dependent group, greater Stroop-related activity in regions including the dorsal anterior cingulate cortex was associated with less cannabis use during treatment. Greater activity in regions including the ventral striatum was associated with less cannabis use during 1-year posttreatment follow-up. These data suggest that lower cognitive-control-related neural activity in classic ‘control' regions (eg, dorsolateral prefrontal cortex and dorsal anterior cingulate) and classic ‘salience/reward/learning' regions (eg, ventral striatum) differentiates cannabis-dependent individuals from healthy individuals and relates to less abstinence within-treatment and during long-term follow-up. Clinically, results suggest that treatment development efforts that focus on enhancing cognitive control in addition to abstinence may improve treatment outcomes in cannabis dependence.

Spiders perform many essential ecological services, yet humans often experience negative emotions toward spiders. These emotions can lead to the avoidance of beneficial events. These emotions may affect beliefs about what should or should not be included in a science curriculum. This study investigated how activities with living spiders affected preservice middle school science teachers’ emotions and beliefs. Prior to the activities both groups (i.e., treatment and control) had moderate to extreme fear and disgust toward the spider. The teachers that participated in the spider activities (i.e., treatment group) had much lower levels of fear and disgust after performing the spider activities than the control group that did not participate in the spider activities. The control group continued to have elevated levels of fear and disgust toward the spider throughout the study. Before the spider activities neither group planned to incorporate information about spiders or information about the essential ecological services of spiders into their science classroom. After the treatment group participated in the spider activities, the teachers had definitive plans to teach their students about spiders and the essential ecological services that they provide. The control group remained unchanged and had no plans to teach this information to their students. PMID:29382186

1. A total of 360 1-d-old male commercial Arbor Acre broiler chickens were randomly assigned to 5 groups (6 replicates of 12 birds each) to evaluate the dietary effects of polysavone (0·5, 1·0 and 1·5 g/kg), a natural extract from alfalfa, and 0·15 g/kg chlortetracycline (CTC) on growth performance, antioxidation and meat quality of broiler chickens. 2. Over the 6-week study, feed intake increased significantly with CTC supplementation and final body weight (BW) was significantly higher for 1·0 g/kg polysavone and 0·15 g/kg CTC treatments. Feed:gain ratio was not significantly affected by the dietary treatments. 3. At 3 weeks of age, serum total superoxide dismutase (T-SOD) activity for all polysavone treatments was significantly higher than controls, liver T-SOD activity in 1·5 g/kg polysavone group was significantly higher than the control and CTC groups, and serum glutathione peroxidase (GSHPx) activity for 1·5 g/kg polysavone and liver GSHPx activity in all polysavone groups were significantly higher than CTC. 4. At 6 weeks of age, serum and liver T-SOD activity in 1·5 g/kg polysavone group and liver GSHPx activity for all polysavone treatments were higher significantly than the control and CTC groups, and serum malondialdehyde (MDA) content for all polysavone treatments was significantly lower than CTC. 5. Breast muscle T-SOD activity and pH value at 6 weeks of age were significantly higher and MDA content was significantly lower in 1·0 and 1·5 g/kg polysavone groups than in the control and CTC groups. Breast muscle shear force was significantly lower in l·5 g/kg polysavone group compared with the control, and drip loss for all polysavone treatments was significantly lower than CTC. 6. It was indicated that polysavone modulates antioxidation and modifies meat quality, but with no adverse effect on performance of broiler chickens, and that CTC can be beneficial to performance but has no beneficial effect on antioxidant function or meat quality.

Service user participation is a central principle in mental healthcare, and the opportunity to self-refer to inpatient treatment is used to increase service user involvement and activation. The aim of this study was to investigate the short-term effect of a self-referral system in an inpatient rehabilitation unit at a community mental health center on patient activation and recovery in individuals with severe mental disorders. A randomized controlled study including 53 patients (41 % females, mean age 40 years). Twenty-six patients in the intervention group were given a contract for self-referral to inpatient treatment, limited to maximum 5 days and a quarantine time of 14 days between each stay. The control group (27 participants) received treatment as usual, and was offered the intervention after 1 year. The Patient Activation Measure was the primary outcome and secondary outcome was the Recovery Assessment Scale. Mixed models were used to assess group differences. During the 4 months period, 15 (58 %) of 26 participants in the intervention group used the contract of self-referral to inpatient treatment. The intervention group had more admissions than the control group but both groups had a similar total use of inpatient days and out-patient consultations. The self-referral to inpatient treatment counted for 11 % of all inpatient days for the intervention group. There were no significant differences in the outcome between the groups on patient activation (estimated mean difference 2.7, 95 % confidence interval = -5.5 to 10.8, p = 0.52) or recovery (estimated mean difference 0.01, 95 % confidence interval = -0.3 to 0.3, p = 0.92). Giving persons with severe mental disorders the possibility to self-refer to inpatient treatment did not change their level of patient activation and recovery after 4 months and did not lead to increased use of health services. The cost-effectiveness and long-term effect of self-referral to inpatient treatment should be investigated further. NCT01133587 , clinicaltrials.gov.

In this study, we comparatively evaluated the effects of the flurochloridone as well as flurochloridone and exogenously applied salicylic acid (SA) on Helianthus annuus L. to find out herbicide-induced toxicity reducing influence of SA. We examined and compared the physiological and biochemical effects of different concentrations of flurochloridone (11, 32 and 72 mM) in both the SA pre-treated and non-treated plants. The plants treated with flurochloridone exhibited reduced total chlorophyll, carotenoid, and relative water content compared to the control group, whereas the plants that were pre-treated with SA exhibited relatively higher values for the same physiological parameters. In the SA non-treated plants, the superoxide dismutase, glutathione reductase and glutathione S-transferase activities were increased in the treatment groups compared to the control group. In the treatment groups, these enzyme activities were decreased in the SA-pre-treated plants compared to the non-treated plants. Ascorbate peroxidase and catalase activities decreased in the flurochloridone-treated plants compared to the control plants. The ascorbate peroxidase activity increased in the control groups but decreased in the treatment groups in the SA pre-treated plants compared to the non-treated plants. However, SA treatment decreased the activity of catalase in the control and treatment groups compared to the plants that were not treated with SA. Flurochloridone treatment increased the malondialdehyde content in the treated groups compared to the control groups, whereas SA-pretreatment decreased malondialdehyde content compared to plants that were not treated with SA. Flurochloridone treatment increased endogenous SA content compared to the control. Although the residual levels of herbicide in the plants increased proportionately with increasing herbicide concentrations, the SA-pre-treated plants exhibited reduced residual herbicide levels compared to the plants that were not treated with SA. These results indicate that the flurochloridone induces various physiological and biochemical responses in non-target plants and that treatment with exogenous SA can increase stress resistance by altering these responses.

To compare the efficacy and safety of ranibizumab 0.5 mg, guided by visual acuity (VA) stabilization or disease activity criteria, versus verteporfin photodynamic therapy (vPDT) in patients with visual impairment due to myopic choroidal neovascularization (CNV). Phase III, 12-month, randomized, double-masked, multicenter, active-controlled study. Patients (N = 277) with visual impairment due to myopic CNV. Patients were randomized to receive ranibizumab on day 1, month 1, and thereafter as needed guided by VA stabilization criteria (group I, n = 106); ranibizumab on day 1 and thereafter as needed guided by disease activity criteria (group II, n=116); or vPDT on day 1 and disease activity treated with ranibizumab or vPDT at investigators' discretion from month 3 (group III, n = 55). Mean average best-corrected visual acuity (BCVA) change from baseline to month 1 through months 3 (primary) and 6, mean BCVA change and safety over 12 months. Ranibizumab treatment in groups I and II was superior to vPDT based on mean average BCVA change from baseline to month 1 through month 3 (group I: +10.5, group II: +10.6 vs. group III: +2.2 Early Treatment Diabetic Retinopathy Study [ETDRS] letters; both P<0.0001). Ranibizumab treatment guided by disease activity was noninferior to VA stabilization-guided retreatment based on mean average BCVA change from baseline to month 1 through month 6 (group II: +11.7 vs. group I: +11.9 ETDRS letters; P<0.00001). Mean BCVA change from baseline to month 12 was +13.8 (group I), +14.4 (group II), and +9.3 ETDRS letters (group III). At month 12, 63.8% to 65.7% of patients showed resolution of myopic CNV leakage. Patients received a median of 4.0 (group I) and 2.0 (groups II and III) ranibizumab injections over 12 months. No deaths or cases of endophthalmitis and myocardial infarction occurred. Ranibizumab treatment, irrespective of retreatment criteria, provided superior BCVA gains versus vPDT up to month 3. Ranibizumab treatment guided by disease activity criteria was noninferior to VA stabilization criteria up to month 6. Over 12 months, individualized ranibizumab treatment was effective in improving and sustaining BCVA and was generally well tolerated in patients with myopic CNV.

The aim of the present study was to investigate the effect of the caspase-3 inhibitor z-DEVD-fmk on the apoptosis of the brain tissues of rats with acute cerebral infarction. Middle cerebral artery occlusion was used to establish a rat model of infarction, and the rats were randomly divided into a sham group (n=15), model group (n=15) and treatment group (n=15). z-DEVD-fmk (2.5 µg/kg) was injected into the intracranial artery of rats in the treatment group, while the same volume of phosphate-buffered saline solution was administered to the rats of the sham and model groups. After 48 h, all rats were sacrificed and their brain tissues were removed. The caspase-3 mRNA level, protein level and activity, brain cell apoptosis index and infarction scope of the three groups were analyzed. Neurological impairment was also assessed. At 48 h after model establishment, the caspase-3 mRNA and protein levels in the brain tissues of the model group were significantly higher than those of the sham group, and those in the treatment group were significantly lower than those in the model group (P<0.05); however, they remained significantly higher than those in the sham group. Caspase-3 activity in the model group was significantly higher than that in the sham group, and treatment with the caspase-3 inhibitor significantly reduced caspase-3 activity compared with that in the model group (P<0.05). The apoptosis index and infarction scope in the model and treatment groups were significantly increased compared with those in the sham group, and were significantly lower in the treatment group than in the model group (P<0.05). The neurological impairment of rats in the model and treatment groups was increased significantly compared with that in the sham group, and the treatment group exhibited a significantly lower level of neurological impairment than the model group (P<0.05). In conclusion, the caspase-3 inhibitor z-DEVD-fmk effectively inhibited apoptosis and delayed the necrosis of brain tissue cells in rats with acute cerebral infarction, and had certain protective effects on brain tissue.

Background Occupational therapy (OT) is a critical component of the rehabilitation process after spinal cord injury (SCI), the constitution of which has not been studied or documented in full detail previously. Objective To describe the type and distribution of SCI rehabilitation OT activities, including the amount of time spent on evaluation and treatment, and to discuss predictors (patient and injury characteristics) of the amount of time dedicated to OT treatment activities. Methods Six inpatient rehabilitation centers enrolled 600 patients with traumatic SCI in the first year of the SCIRehab. Occupational therapists documented 32 512 therapy sessions including time spent and specifics of each therapeutic activity. Analysis of variance and contingency tables/chi-square tests were used to test differences across neurologic injury groups for continuous and categorical variables. Results SCIRehab patients received a mean total of 52 hours of OT over the course of their rehabilitation stay. Statistically significant differences among four neurologic injury groups were seen in time spent on each OT activity. The activities that consumed the most OT time (individual and group sessions combined) were strengthening/endurance exercises, activities of daily living (ADLs), range of motion (ROM)/stretching, education, and a grouping of ‘therapeutic activities’ that included tenodesis training, fine motor activities, manual therapy, vestibular training, edema management, breathing exercise, cognitive retraining, visual/perceptual training desensitization, and don/doff adaptive equipment. Seventy-seven percent of OT work occurred in individual treatment sessions, with the most frequent OT activity involving ADLs. The variation in time (mean minutes per week) spent on OT ROM/stretching, ADLs, transfer training, assessment, and therapeutic activities can be explained in part by patient and injury characteristics, such as admission Functional Independence Measure (FIM) score, neurologic injury group, and the medical severity of illness score. Conclusion OT treatment patterns for patients with traumatic SCI show much variation in activity selection and time spent on activities, within and among neurologic level of injury groups. Some of the variation can be explained by patient and injury characteristics. Almost all patients with SCI participated in strengthening/endurance and ROM/stretching exercises during OT treatment and these two activities are where the most time was spent when therapy provided in individual and group settings was combined. ADL work consumed the most time in individual therapy sessions. PMID:21675355

This study analyzed the behavior of human osteoblasts cultured on porous titanium specimens, with and without biomimetic treatment, compared to dense titanium. The experiment had seven groups: Group 1: cells cultured on polystyrene of culture plate wells; Group 2: cells cultured on dense titanium specimen; Group 3: specimen with 33.79% of pores; Group 4: 41.79% of pores; Groups 5, 6 and 7: specimens similar to groups 2, 3 and 4, yet with biomimetic treatment. Real time-polymerase chain reaction with reverse transcription of the following genes was performed: prostaglandin E2 synthase, integrin β1, osterix, Runx2, Interleukin 6, macrophage colony stimulating factor, apolipoprotein E and others. The study achieved data on cell adhesion, growth and viability, total protein content, alkaline phosphatase activity and quantity of mineralized nodule formations. Data were statistically evaluated. Adherent cells and alkaline phosphatase activity were similar in titanium specimens, regardless of the groups. Biomimetic treatment reduced the total protein activity and the viability of tested cells. Most tested genes had statistically similar expression in all groups. The tested porosities did not cause alterations in osteoblast behavior and the biomimetic treatment impaired the biocompatibility of titanium causing cytotoxicity. Copyright © 2015 Elsevier B.V.

A significant mean increase of 18% in erythrocyte sodium pump activity (p less than 0.01, t test) was observed during lithium treatment, as compared with the activity before lithium treatment was started, in a group of 20 patients who were treated with lithium therapy for a variety of psychiatric conditions. The mean level of erythrocyte membrane ouabain-sensitive ATPase activity in a group of 35 subjects who were receiving lithium therapy was significantly higher than that of a different group of 38 subjects who were not receiving lithium therapy (p less than 0.005, t test). These observations may offer a biochemical mode of action for lithium in the treatment of bipolar affective disorder, since a deficiency of sodium pump activity has been shown to be associated with that disorder.

To explore the effects of low-dose insulin on oxidation-reduction of heart and kidney in rats immediately after severe burns. Twenty four male Sprague-Dawley (SD) rats were randomly divided into 3 groups of sham burn, burn and treatment (n = 8 each). The sham burn group was placed into 37 °C warm water for 15 seconds to simulate burn process and received no fluid replacement. The burn and treatment groups were immersed into (95 ± 0.5) °C hot water for 15 seconds to make a rat model of 30% total burn surface area, III degree burn injury and immediately received an intraperitoneal injection of physiological saline (40 ml/kg). At the same time, a subcutaneous injection of insulin (1.0 U×kg(-1)×d(-1)) was given in the treatment group and a subcutaneous injection of same-volume physiological saline in the burn group. The rats were sacrificed after 24 post-scald hours (PSH). Abdominal aortic blood was collected for an analysis of blood glucose. The oxidation and antioxidation parameters of heart and kidney, such as malondialdehyde (MDA), xanthine oxidase (XO), myeloperoxidase (MPO), total superoxide dismutase (T-SOD), superoxide dismutase 1, 2 (SOD1, 2), catalase (CAT) and glutathione peroxidase (GPx), were detected by spectrophotometry. Compared with the sham burn group, MDA content, XO and MPO activities of heart and kidney were significantly higher in the burn group (all P < 0.05); in the treatment group, MDA content and XO activity of heart were significantly lower than the burn group ((0.85 ± 0.07) vs (1.11 ± 0.07) nmol/mg, (69.72 ± 1.94) vs (77.21 ± 2.10) U/g) while the MPO activities of heart and kidney were significantly lower (all P < 0.05).compared with the sham burn group, the activities of T-SOD, CAT, GPx of heart and kidney were significantly lower in the burn group, SOD1 activity of kidney was significantly lower, but SOD2 activity of kidney was significantly higher while SOD2 activity of heart was significantly lower (all P < 0.05); Compared with the burn group, the activities of T-SOD and SOD1 of heart in the treatment group were significantly higher ((83.5 ± 2.5) vs (79.6 ± 3.2), (62.8 ± 2.3) vs (58.8 ± 3.0) U/mg), CAT and GPx activity of heart and kidney were significantly higher (all P < 0.05). Compared with the sham burn group, blood glucose in the burn and treatment group were significantly higher ((7.81 ± 0.30), (7.19 ± 0.22) vs (6.30 ± 0.24) mmol/L) and blood glucose in the treatment group was significantly lower than the burn group((7.81 ± 0.30) mmol/L)(all P < 0.05). During an early stage, a low-dose insulin may intervene in heart tissue lipid peroxidation of severely burned rats. And differences exist in the effects of oxidation-reduction between heart and kidney.

Cognitive rehabilitation programs have demonstrated efficacy in improving cognitive functions in Parkinson's disease (PD), but little is known about cerebral changes associated with an integrative cognitive rehabilitation in PD. To assess structural and functional cerebral changes in PD patients, after attending a three-month integrative cognitive rehabilitation program (REHACOP). Forty-four PD patients were randomly divided into REHACOP group (cognitive rehabilitation) and a control group (occupational therapy). T1-weighted, diffusion weighted and functional magnetic resonance images (fMRI) during resting-state and during a memory paradigm (with learning and recognition tasks) were acquired at pre-treatment and post-treatment. Cerebral changes were assessed with repeated measures ANOVA 2 × 2 for group x time interaction. During resting-state fMRI, the REHACOP group showed significantly increased brain connectivity between the left inferior temporal lobe and the bilateral dorsolateral prefrontal cortex compared to the control group. Moreover, during the recognition fMRI task, the REHACOP group showed significantly increased brain activation in the left middle temporal area compared to the control group. During the learning fMRI task, the REHACOP group showed increased brain activation in the left inferior frontal lobe at post-treatment compared to pre-treatment. No significant structural changes were found between pre- and post-treatment. Finally, the REHACOP group showed significant and positive correlations between the brain connectivity and activation and the cognitive performance at post-treatment. This randomized controlled trial suggests that an integrative cognitive rehabilitation program can produce significant functional cerebral changes in PD patients and adds evidence to the efficacy of cognitive rehabilitation programs in the therapeutic approach for PD.

Experimental animal model to assess ischemic spinal cord injury following occlusion of the thoraco-abdominal aorta. To measure whether melatonin administered to rabbits before and after occlusion exerts an effect on the repair of ischemia-reperfusion (IR) injury. Medical Biology Laboratory, Inonu University, Malatya, Turkey. Rabbits were divided into three IR treatment groups and one sham-operated (ShOp) control group. The three treatment groups had their infrarenal aorta temporarily occluded for 25 min, while the ShOp group had laparotomy without aortic occlusion. Melatonin was administered either 10 min before aortic occlusion or 10 min after the clamp was removed. Physiologic saline was administered to the control animals. After treatment, the animals were euthanized and lumbosacral spinal cord tissue was removed for the determination of relevant enzyme activities. Malondialdehyde levels, indicating the extent of lipid peroxidation, were found to be significantly increased in the nonmelatonin treated (IR) group when compared to the ShOp group. Melatonin, whether given to pre- or post occlusion groups, suppressed malondialdehyde levels below that of the ShOp group. Catalase (CAT) and glutathione peroxidase (GSH-Px) enzyme activities were increased in the IR group compared to the ShOp group. Melatonin given preocclusion resulted in a significant decrease in both CAT and GSH-Px enzyme levels. The superoxide dismutase (SOD) enzyme activity was decreased in the ischemia-reperfusion treatment group. However, the melatonin treatment increased SOD enzyme activity to levels approximating that of the ShOp group. To our knowledge, this is the first study that shows the effects of melatonin administered both pre- and postischemia on induced oxidative damage to injured spinal cords. Our data also expands on reports that melatonin administration may significantly reduce the incidence of spinal cord injury following temporary aortic occlusion.

Sarcopenia is an age-related decline in skeletal muscle mass and function that is multifactorial in etiology. Age-related changes in the renin-angiotensin system (RAS), increased oxidative stress, and chronic inflammation likely all contribute to its development. Losartan, an angiotensin II type I receptor blocker (ARB) decreases RAS activity and likely influences oxidative stress and inflammation. Given this, we hypothesized that losartan would improve activity levels and parameters related to inflammation and oxidative stress in older mice. We sought to test this hypothesis by comparing functional and molecular parameters between 18-month-old C57BL/6 mice treated with 50-70 mg/kg/day of losartan over a 4 month-period and age- and gender-matched mice receiving placebo. Losartan treatment significantly improved several activity measurements during treatment period compared to placebo controlled group, including increased time on treadmill, traveling activity, standing activity, and decreased grid contacts (p-values < 0.05, 0.001, 0.01; and 0.04 respectively). Grip strength did not improve in treatment group relative to control group over time. Serum IL-6 level in the treated group was significantly lower than that in the control group at the end of treatment, (30.3±12.9 vs. 173.0±59.5 pg/ml, p< 0.04), and mRNA expression of antioxidant enzymes catalase (3.9±0.9 vs. 1.0±0.4) and glutathione peroxidase (4.7±1.1 vs. 1.0±0.4) was significantly higher, P-value: 0.02, and 0.03 respectively) in quadriceps muscle after 4 months of treatment in treated and control groups. These results support the hypothesis that chronic losartan treatment improves skeletal muscle related activity measures in older mice, and that it is associated with more favorable relevant biological profiles in the treatment group. Additional studies are needed to 1) further quantify this functional improvement, 2) further identify mechanisms that influence this improvement, and 3) provide additional rationale for translating these findings into older adults.

This study was performed to investigate the anti-wrinkle effects of topical applications of green tea extract with high antioxidant activity by tannase treatment. Increases in gallic acid (GA), (-)-epigallocatechin (EGC), and (-)-epicatechin (EC) were observed in the green tea extract after tannase treatment. This study was performed to investigate the anti-wrinkle effects of topical applications of green tea extract exhibiting high antioxidant activity after tannase treatment. Subjects, randomly divided into two groups, received the application of either tannase-converted green tea extract (TGE) or normal green tea extract (NGE) on their crow's feet for 8 weeks. The anti-wrinkle effects were evaluated with two methods: (i) self-assessment; and (ii) average roughness of skin surface (R(a), R(z), and R(t) value) using skin replica and Skin-Visiometer SV 600. The scavenging abilities of TGE against radicals were significantly higher compared to NGE. The evaluation of skin wrinkle index values after 8 weeks of treatment showed that reductions of R(a), R(z), and R(t) values in the TGE group were significantly greater than in the NGE group, which indicated that tannase treatment improved the anti-wrinkle effects of green tea extract. According to the overall ratings for wrinkle treatment by applying the formulations, most of the TGE group (63.60%) reported marked or moderate improvement in wrinkles compared with only 36.30% of the NGE group. Tannase treatment can improve the antioxidant activity of green tea extract, conferring anti-wrinkle activities. These results suggest that TGE may have beneficial properties as an anti-wrinkle agent. © 2013 Wiley Periodicals, Inc.

The aim of the present study was to evaluate the effect of magnetic stimulation on urodynamic stress incontinence refractory to pelvic floor muscle training in a randomized sham-controlled study. Female patients with urodynamic stress incontinence who had not been cured by pelvic floor muscle training were randomly assigned at a ratio of 2 : 1 to either active treatment or sham treatment for 10 weeks. The randomization was made using magnetic cards for individuals indicating active or sham stimulation. The primary endpoint was changes in the number of incontinence episodes/week, with secondary endpoints of the degree of incontinence (in g/day; determined using the pad test), the total score on the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), the ICIQ quality of life (QOL) score, and the abdominal leak point pressure (ALPP) on urodynamic study. Although 39 patients were enrolled in the study, 9 dropped out, leaving a total patients for analysis (18 in the active treatment group, 12 in the sham treatment group). The number of incontinence episodes/week, the degree of incontinence, total ICIQ-SF score, ICIQ-QOL score, and ALPP were significantly improved after active treatment compared with baseline (all P < .05), but did not change significantly after sham treatment. There was a significant intergroup difference with regard to changes from baseline in the ICIQ-SF and ALPP in favor of the active treatment group (P < .05). There were no significant differences in any other parameters between the 2 groups. Treatment-related adverse events were not found in both groups. Magnetic stimulation was effective in treating urodynamic stress incontinence. © 2017 John Wiley & Sons Australia, Ltd.

The objective of this study was to investigate the effect of Minocycline in the life span, motor activity, and lipid peroxidation of Drosophila melanogaster treated with manganese. Two days after emerging from the pupa male wild-type D. melanogaster were fed for 13 days with corn media containing 15 mM manganese. Then, they were divided in six groups of 300 flies each: group (a) remained treated with manganese (Mn group); group (b) began treatment with Minocycline (0.05 mM) (Mn-Minocycline group); group (c) received no additional treatment (Mn-no treatment group); group (d) simultaneously fed with manganese and Minocycline (Mn+Minocycline group). Additionally, a control (group e) with no treatment and another group (f) fed only with Minocycline after emerging from the pupa were added. All the manganese treated flies (group a) were dead on the 25th day. The life span in group f (101.66±1.33 days, mean S.E.M.) and of group b (97.00±3.46 days) were similar, but in both cases it was significantly higher than in group e (68.33±1.76 days), group c (67.05±2.30 days) and in those of group d (37.33±0.88). Manganese (groups a and d) decreased motor activity in D. melanogaster. In the Minocycline fed flies (groups b and f) a higher motor activity was detected. In Mn-Minocycline and Mn+Minocycline treated flies a significant decrease of MDA levels was detected when compared to the Minocycline group indicating that Minocycline and Mn appear to have a synergistic effect. In conclusion, Minocycline increased the life span and motor activity and decreased MDA formation of manganese treated D. melanogaster, probably by an inhibition of the production of reactive oxygen species. Manganese also exerted an antioxidant effect as shown by the significant decrease of MDA levels when compared to control flies. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

2000-10-01

This study investigated the effects active learning strategies had on college students' achievement, motivation, and self-efficacy, in a human physiology course for non-majors. A continuum-based active learning instructional model was implemented over the course of a semester to assess the effects on the variables and specific student outcomes of learning mentioned above. In addition analyses were conducted to explore what learner characteristics contributed to the successful implementation of the model such as students' gender, classification, major, grade point average, ACT and SAT scores, motivation, and self-efficacy. A quasi-experimental, Solomon-4 Group design was undertaken on 171 students in a small west-Texas university. Treatment groups were taught using the model while controls were taught using traditional lecture methods. Students were administered a comprehensive physiology content exam, sections of the Motivated Strategies for Learning Questionnaire, and attitude surveys to assess the effects of the continuum-based active learning strategies. Factorial analyses indicated the treatment group acquired significantly more content knowledge and were significantly more self-efficacious than students in the control group. There were no significant differences in motivation. Factorial and modified regression analyses in the aptitude by treatment interaction exploration determined that males in the treatment group performed significantly better on the comprehensive physiology content exam versus males in the control group. While females performed better overall than males, there were no significant differences in achievement between females in the treatment group and those in the control. No significant interactions were found for the other learner characteristics. The results also indicated that students' general cognitive ability as measured by their grade point average, ACT, and SAT scores and their self-efficacy contributed significantly to their achievement. Attitude surveys indicated that students in both the treatment and control groups demonstrated a positive attitude toward active learning, believed it helped them to learn the material, and would choose an active learning course in the future if given the opportunity. This study demonstrated that continuum-based active learning strategies used in this context, improved students' content acquisition and self-efficacy and had wide applicability with a number of learner characteristics.

The study evaluated the effectiveness of an 8-week combined group plus individual 12-step facilitative intervention on stimulant drug use and 12-step meeting attendance and service. Multisite randomized controlled trial, with assessments at baseline, mid-treatment, end of treatment, and 3- and 6-month post-randomization follow-ups (FUs). Intensive outpatient substance treatment programs. Individuals with stimulant use disorders (n = 471) randomly assigned to treatment as usual (TAU) or TAU into which the Stimulant Abuser Groups to Engage in 12-Step (STAGE-12) intervention was integrated. Urinalysis and self-reports of substance use and 12-step attendance and activities. Group sessions focused on increasing acceptance of 12-step principles; individual sessions incorporated an intensive referral procedure connecting participants to 12-step volunteers. Compared with TAU, STAGE-12 participants had significantly greater odds of self-reported stimulant abstinence during the active 8-week treatment phase; however, among those who had not achieved abstinence during this period, STAGE-12 participants had more days of use. STAGE-12 participants had lower Addiction Severity Index Drug Composite scores at and a significant reduction from baseline to the 3-month FU, attended 12-step meetings on a greater number of days during the early phase of active treatment, engaged in more other types of 12-step activities throughout the active treatment phase and the entire FU period, and had more days of self-reported service at meetings from mid-treatment through the 6-month FU. The present findings are mixed with respect to the impact of integrating the STAGE-12 intervention into intensive outpatient drug treatment compared with TAU on stimulant drug use. However, the results more clearly indicate that individuals in STAGE-12 had higher rates of 12-step meeting attendance and were engaged in more related activities throughout both the active treatment phase and the entire 6-month FU period than did those in TAU.

Plantar fasciitis can be a chronic and debilitating condition affecting athletes of all levels. The aim of this study is to compare treatment outcomes for the treatment of chronic plantar fasciitis in athletes, comparing focused extra corporeal sound wave therapy (ESWT) and the surgical endoscopic plantar fasciotomy (EPF). A total of 37 eligible patients were enrolled in the study between May 2006 and December 2008 at a single institution. Patients were either enrolled in the surgical group, or to the ESWT group which included a placebo controlled, randomized group (P-ESWT). Pre and post Visual Analog Scores (VAS) and Roles and Maudlsey (RM) scores were recorded and compared between the three groups. The patient's return to activity (RTA) was also documented. The results showed statistical improvement within the EPF and ESWT groups with both VAS & RM scores, with EPF being significantly better than both ESWT and P-ESWT in terms of treatment outcomes. Patients enrolled in the ESWT were able though to continue with their exercise regimen, while the EPF group was able to return to their athletic activity in an average of 2.8 months. In conclusion, EPF and ESWT are both effective forms of treatment for chronic plantar fasciitis; EPF being superior in outcomes yet ESWT treatment could be preferable since the athlete can remain active during treatment.

Interference of ongoing neuronal activity and brain stimulation motivated this study to combine repetitive transcranial magnetic stimulation (rTMS) and relaxation techniques in tinnitus patients. Forty-two patients were enrolled in this one-arm proof-of-concept study to receive ten sessions of rTMS applied to the left dorsolateral prefrontal cortex and temporo-parietal cortex. During stimulation, patients listened to five different kinds of relaxation audios. Variables of interest were tinnitus questionnaires, tinnitus numeric rating scales, depressivity, and quality of life. Results were compared to results of historical control groups having received the same rTMS protocol (active control) and sham treatment (placebo) without relaxation techniques. Thirty-eight patients completed the treatment, drop-out rates and adverse events were low. Responder rates (reduction in tinnitus questionnaire (TQ) score ≥5 points 10 weeks after treatment) were 44.7 % in the study, 27.8 % in the active control group, and 21.7 % in the placebo group, differing between groups on a near significant level. For the tinnitus handicap inventory (THI), the main effect of group was not significant. However, linear mixed model analyses showed that the relaxation/rTMS group differed significantly from the active control group showing steeper negative THI trend for the relaxation/rTMS group indicating better amelioration over the course of the trial. Deepness of relaxation during rTMS and selection of active relaxation vs. passive listening to music predicted larger TQ. All remaining secondary outcomes turned out non-significant. This combined treatment proved to be a safe, feasible and promising approach to enhance rTMS treatment effects in chronic tinnitus.

The current treatment for human brucellosis requires a combination of antibiotics for long periods of time, and the reported incidence and prevalence of the disease vary widely in nomadic livestock of Mongolia. The objective of the present study was to evaluate the in vivo antibacterial activity of the C. mongolica root extract against B. melitensis. In this study, we used of 6 groups of mice (n = 5). Five groups of BALB/c mice were inoculated intraperitoneally with the M16 strain of B. melintensis, as follows: (i) one group was used for pretreatment monitoring; (ii) the control group was administered 2% Tween 80 and was used as the non-treatment group; and the other three groups were treated with one oral gavage per day for 21 days with (iii) doxycycline (2 mg/day), (iv) doxycycline (1 mg/day) with root extract (20 mg/day), and (v) C. mongolica root extract (20 mg/day). The one group that was kept non-infected was used as a healthy control group. This study demonstrated that daily treatment with doxycycline alone and in combination with C. mongolica root extract significantly reduced splenic infection at the end of treatment. However, the spleen index of both the doxycycline-treated and the combination-treated groups of mice decreased by approximately 50% compared to that of the healthy control mouse group. Treatment with the C. mongolica root extract resulted in a 1.47log reduction in splenic infection compared to the non-treatment group, and the spleen index of the C. mongolica-treated group of mice was the same as that of the normal mouse group. In all treatment groups, neutrophil phagocytic activity significantly decreased, and all treatment groups demonstrated splenic regeneration. The present study showed that the C. mongolica root extract may be useful in the treatment of brucellosis patients, in combination with doxycycline or other antibiotics, to reduce the toxicity of high-dosage antibiotics, to prevent the development of antibiotic resistance and to prevent Brucella infection.

To determine whether topical hypotensive medications prevent postoperative ocular hypertension (POH) after phacoemulsification. 52 client-owned dogs (88 eyes). Diabetic and nondiabetic dogs having undergone phacoemulsification were included in this retrospective study. The control group received no ocular hypotensive medications. The treatment groups received latanoprost, dorzolamide, or dorzolamide/timolol, beginning immediately after surgery, for 2-week duration. IOPs were obtained at initial examination followed by 4 h, 24 h, 7 days, and 14 days postoperatively. POH was defined as an IOP above 20 mmHg (POH20) or 25 mmHg (POH25). POH20 occurred in 33 of 87 eyes (37.93%), including 11 of 21 eyes (52.38%) in the control group, three of 23 eyes (13.04%) in the latanoprost group, eight of 15 eyes (53.33%) in the dorzolamide group, and 11 of 28 eyes (39.29%) in the dorzolamide/timolol group. Active treatment groups were compared to the control group, and the overall group effect was not significant (P = 0.11). POH25 occurred in 22 of 86 eyes (25.58%), including seven of 21 eyes (33.33%) in the control group, two of 23 eyes (8.70%) in the latanoprost group, five of 15 eyes (33.33%) in the dorzolamide group, and eight of 27 eyes (29.63%) in the dorzolamide/timolol group. Active treatment groups were compared to the control group, and the overall group effect was not significant (P = 0.31). Intraoperative use of intracameral tissue plasminogen activator significantly decreased the chances of POH25 (P = 0.0063). The latanoprost group had a substantially lower percentage of POH 20 and POH25 compared to the control and other active treatment groups, although statistical significance was not achieved. Intraoperative intracameral tissue plasminogen activator decreased the incidence of POH25. © 2017 American College of Veterinary Ophthalmologists.

Purpose. We evaluated the effect of sulforaphane (SFN) treatment on the function and changes of expression of Nrf2-ARE pathway in the bladder of rats with bladder outlet obstruction (BOO). Materials and Methods. A total of 18 male Sprague-Dawley rats at age of 8 weeks were divided into 3 groups (6 of each): the sham operated group, the BOO group, and the BOO+SFN group. We examined histological alterations and the changes of oxidative stress markers and the protein expression of the Nrf2-ARE pathway. Results. We found that SFN treatment could prolong micturition interval and increase bladder capacity and bladder compliance. However, the peak voiding pressure was lower than BOO group. SFN treatment can ameliorate the increase of collagen fibers induced by obstruction. SFN treatment also increased the activity of SOD, GSH-Px, and CAT compared to the other groups. The level of bladder cell apoptosis was decreased in BOO rats with SFN treatment. Moreover, SFN could reduce the ratio of Bax/Bcl-2 expression. Furthermore, SFN could activate the Nrf2 expression with elevation of its target antioxidant proteins. Conclusions. The sulforaphane-mediated decrease of oxidative stress and activation of the Nrf2-ARE pathway may ameliorate bladder dysfunction caused by bladder outlet obstruction. PMID:27433291

The impact of different Met sources on broiler fecal odor volatiles was determined by evaluating the types of sulfur compounds produced in broiler excreta. Two experiments were conducted using straight-run broiler chicks randomly distributed in battery cages, with 3 replicate pens of 16 birds each. The treatment groups were 1) dry Met hydroxy analogue (dry MetHA), 2) sodium methioninate aqueous solution (NaMet), 3) liquid Met hydroxy analogue (Liq MetHA), 4) D,L- Met, and 5) no supplemental Met (control group). The Met activities of each Met source were 52, 45.9, 88, and 98%, respectively. All diets were formulated to contain either 0.8% (experiment 1) total Met activity or 0.5% Met activity in the starter and 0.38% Met activity in the grower (experiment 2) (except the control group, 0.35% Met activity), but otherwise met NRC nutrient requirements (NRC, 1994). Diets were fed ad libitum from d 1 to 6 wk of age. There were no significant differences in BW among the treatments. All excreta were collected in litter pans lined with aluminum foil. In experiment 1, at wk 6, broiler excreta were collected for a 24-h period, and 4.5 g of broiler excreta from each treatment group was collected into 15-mL headspace vials. Samples were analyzed by gas chromatography/mass spectrometry (GC/MS). The volatile sulfur compounds that were identified and quantified in the broiler excreta were H2S, carbonyl sulfide (COS), methyl mercaptan (CH3SH), dimethyl disulfide (CH3SSCH3), and dimethyl trisulfide (CH3SSSCH3). The NaMet treatment group had significantly higher concentrations of H2S, COS, and CH3SSCH3 compared with all other treatment groups. The Liq MetHA group had significantly lower concentrations of H2S, COS, CH3SH, and CH3SSCH3 compared with the other treatment groups. The dry MetHA group significantly had the highest concentration of CH4SH. The D,L-Met treatment group had the significantly highest concentration of CH3SSSCH3 and the lowest concentration of H2S. The control group had the significantly lowest concentrations of CH3SH, CH3SSCH3, and CH3SSSCH3 compared with the other treatment groups. In experiment 2, at wk 6, an electronic nose was used to evaluate 15 air samples per treatment group. In addition, 15 air samples (containing 6 to 8 L of air in a Tedlar bag, 3 samples per treatment group) were collected for odor evaluation by a sensory panel. Electronic nose sensor data revealed that volatile compounds in broiler excreta from the control group were significantly different from the other 4 treatment groups. Evaluation of the air samples by a sensory panel determined that there was a statistically significant difference in odor threshold detection between the control group and the other treatment groups. The dilutions to threshold of control group, NaMet, dry MetHA, Liq MetHA, and D,L-Met were 350, 492, 568, 496, and 526 odor units, respectively. These findings demonstrate that dietary Met sources significantly influenced odorous volatile concentrations in broiler excreta.

This study compared the attitudes and the gains of knowledge concerning Lewis structures and polarity of molecules. The students performed a lab exercise in which they drew Lewis structures, constructed models of the molecules, determined the geometry of the molecules, and determined the polarity of the molecules. The control group students constructed models using physical ball-and-stick models. The treatment group students used Spartan Model to construct models. Students from a university and a community college participated in this study. Four lab classes at each school made up the treatment group. Five lab classes at the university and three lab classes at the community college made up the control group. The treatment group classes were selected based on available computer resources. All students in the study were given the Lab Pre Test, Lab Post Test, and the Lecture Post Test to assess the student's ability to answer questions pertaining to Lewis structures and polarity of molecules. An Attitudinal Survey assessed the attitudes of the students who participated in the study. Student interviews were performed to assess the student's attitudes towards the lab exercise. The interviews investigated attitudes about the modeling exercise, Lewis structures, and polarity of molecules. There were no significant differences in the performance of the treatment group when compared to the control group on the performance assessment instruments at the university or the community college. The treatment group students at the university had a more positive attitude about the lab activity. They believed that the lab activity helped them better understand the concepts of Lewis structure and molecular polarity. At the community college, the control group students had a more positive attitude about the lab activity. The students involved in the study believed that the lab activity helped them to understand the concepts of molecular geometry and polarity. The interviews of the treatment group students indicated that they strongly believed that the lab activity helped them better understand the concept of Lewis structures and of molecular polarity. As reflected in the interviews of the treatment group and the control group, the lab activity did not help the students be able to look at a Lewis structure and build a mental image of the molecule. The students believed the electrostatic potential plots generated by Spartan Model were very insightful into the concept of polarity. It gave them a visual representation of a difficult topic.

The aim of the study was to assess the effectiveness of pharmacotherapy and physiotherapy in cervical vertigo treatment. 80 patients with cervical vertigo (41 women and 39 men), aged 20 to 85, were treated by pharmacotherapy or physiotherapy. There were two groups: group I was treated by pharmacotherapy and group II was treated by physiotherapy and kinesitherapy. The effects of vertigo treatment were assessed by positional nystagmus testing according to Cawthorne and Rosen; cervical nystagmus testing in neck rotation test; by everyday task self-control cards and vertigo staging system according to Silvoniemi (0-4 points). The effects of treatment were assessed before therapy, 6 and 12 weeks after therapy. Patients from group I were treated by Nootropil and Betaserc; group II received magnetic Fidel, laserotherapy, massage and kinesitherapy exercises. The obtained results showed that the most useful methods of cervical vertigo diagnosis were neck rotation test and Rose method. The average number of points (according to Silvoniemi scale) on the basis of ten everyday activities, was lower after 6 weeks of treatment than before the treatment and the lowest after 12 weeks of treatment. The difference was higher in group II than in group I. Patients treated by physiotherapy (group II) performed better in everyday activities than the patients treated by pharmacotherapy (group I). Cervical vertigo treatment by physiotherapy is cheap and underestimated method.

Neurofeedback (NF) has gained increasing interest in the treatment of attention-deficit/hyperactivity disorder (ADHD). Given learning principles underlie NF, lasting clinical treatment effects may be expected. This systematic review and meta-analysis addresses the sustainability of neurofeedback and control treatment effects by considering randomized controlled studies that conducted follow-up (FU; 2-12 months) assessments among children with ADHD. PubMed and Scopus databases were searched through November 2017. Within-group and between-group standardized mean differences (SMD) of parent behavior ratings were calculated and analyzed. Ten studies met inclusion criteria (NF: ten studies, N = 256; control: nine studies, N = 250). Within-group NF effects on inattention were of medium effect size (ES) (SMD = 0.64) at post-treatment and increased to a large ES (SMD = 0.80) at FU. Regarding hyperactivity/impulsivity, NF ES were medium at post-treatment (SMD = 0.50) and FU (SMD = 0.61). Non-active control conditions yielded a small significant ES on inattention at post-treatment (SMD = 0.28) but no significant ES at FU. Active treatments (mainly methylphenidate), had large ES for inattention (post: SMD = 1.08; FU: SMD = 1.06) and medium ES for hyperactivity/impulsivity (post: SMD = 0.74; FU: SMD = 0.67). Between-group analyses also revealed an advantage of NF over non-active controls [inattention (post: SMD = 0.38; FU: SMD = 0.57); hyperactivity-impulsivity (post: SMD = 0.25; FU: SMD = 0.39)], and favored active controls for inattention only at pre-post (SMD = - 0.44). Compared to non-active control treatments, NF appears to have more durable treatment effects, for at least 6 months following treatment. More studies are needed for a properly powered comparison of follow-up effects between NF and active treatments and to further control for non-specific effects.

A long-term follow-up of at least 10 years or until death of 44 patients taking part in a controlled prospective trial of prednisolone therapy in hepatitis B antigen negative chronic active hepatitis (lupoid hepatitis) has been performed at the Royal Free Hospital, London. Patients presenting between 1963 and 1967 were randomly allocated into control and treatment groups. Ten year life table survival curves showed a significantly improved survival in the treatment group where 63% of patients were alive at 10 years compared with only 27% in the control group (log rank test, P = 0.03). The median survival in the treatment group was 12.2 years compared with 3.3 years in the control group. The mean duration of treatment was 4.5 years. Age, presence of antinuclear factor, cirrhosis, or level of serum transaminases at presentation did not appear to affect survival. Male patients if untreated had a poorer prognosis than females (P = 0.02). The natural history of chronic active hepatitis appeared from clinical, biochemical, and histological findings to be from an active hepatitis or cirrhosis to inactive macronodular cirrhosis. Prednisolone therapy significantly improved survival by reducing mortality in the early active phase of the disease. PMID:6988304

Tension-type headache (TTH) is one of the most common and costly primary types of headache in clinical practice, with an unknown etiology. This study assessed to investigate oxidative and antioxidative status in patients with chronic tension-type headache (CTTH), and to evaluate possible effect of medical treatment. The study included 41 CTTH patients and 19 age- and sex-matched healthy subjects without headache as controls. The CTTH group comprised 20 patients receiving treatment and 21 untreated patients. We evaluated oxidant/antioxidant status by measuring serum malondialdehyde (MDA) levels and activities of antioxidant enzymes, namely glutathione peroxidase (GSH-Px) and catalase (CAT). Comparison of oxidative parameters in the patient and control groups revealed significantly lower CAT activities and higher MDA level and GSH-Px activities in the patient group. In the CTTH group, serum CAT activities were found to be significantly decreased in patient groups, while serum MDA levels and GSH-Px activities were found to be higher in the untreated CTTH patients. These findings suggest that oxidative stress is increased in the patients with CTTH, and medical treatment abolishes the stress in part. It has been concluded that antioxidant support might be helpful for the patients with CTTH to prevent oxidant stress and peroxidation damages further.

At present, no consensus exists among clinical and academic experts regarding an appropriate placebo for randomized controlled trials (RCTs) of spinal manipulative therapy (SMT). Therefore, we investigated whether it was possible to conduct a chiropractic manual-therapy RCT with placebo. Seventy migraineurs were randomized to a single-blinded placebo-controlled clinical trial that consisted of 12 treatment sessions over 3 months. The participants were randomized to chiropractic SMT or placebo (sham manipulation). After each session, the participants were surveyed on whether they thought they had undergone active treatment (“yes” or “no”) and how strongly they believed that active treatment was received (numeric rating scale 0–10). The outcome measures included the rate of successful blinding and the certitude of the participants’ beliefs in both treatment groups. At each treatment session, more than 80% of the participants believed that they had undergone active treatment, regardless of group allocation. The odds ratio for believing that active treatment was received was >10 for all treatment sessions in both groups (all p < 0.001). The blinding was maintained throughout the RCT. Our results strongly demonstrate that it is possible to conduct a single-blinded manual-therapy RCT with placebo and to maintain the blinding throughout 12 treatment sessions given over 3 months.

In alcohol-dependent patients, alcohol-associated cues elicit brain activation in mesocorticolimbic networks involved in relapse mechanisms. Cue-exposure based extinction training (CET) has been shown to be efficacious in the treatment of alcoholism; however, it has remained unexplored whether CET mediates its therapeutic effects via changes of activity in mesolimbic networks in response to alcohol cues. In this study, we assessed CET treatment effects on cue-induced responses using functional magnetic resonance imaging (fMRI). In a randomized controlled trial, abstinent alcohol-dependent patients were randomly assigned to a CET group (n = 15) or a control group (n = 15). All patients underwent an extended detoxification treatment comprising medically supervised detoxification, health education, and supportive therapy. The CET patients additionally received nine CET sessions over 3 weeks, exposing the patient to his/her preferred alcoholic beverage. Cue-induced fMRI activation to alcohol cues was measured at pretreatment and posttreatment. Compared with pretreatment, fMRI cue-reactivity reduction was greater in the CET relative to the control group, especially in the anterior cingulate gyrus and the insula, as well as limbic and frontal regions. Before treatment, increased cue-induced fMRI activation was found in limbic and reward-related brain regions and in visual areas. After treatment, the CET group showed less activation than the control group in the left ventral striatum. The study provides first evidence that an exposure-based psychotherapeutic intervention in the treatment of alcoholism impacts on brain areas relevant for addiction memory and attentional focus to alcohol-associated cues and affects mesocorticolimbic reward pathways suggested to be pathophysiologically involved in addiction.

Carbon monoxide (CO) toxicity primarily results from cellular hypoxia caused by impedance of oxygen delivery. Studies show that CO may cause brain lipid peroxidation and leukocyte-mediated inflammatory changes in the brain. The aim of this study was to investigate whether magnesium sulphate could prevent or diminish brain lipid peroxidation caused by carbon monoxide toxicity in rats. Fourty rats were divided into five groups of 8 rats each. Group l was not received any agent during the experiment. Group 2 was inhaled CO gas followed by intraperitoneally normal saline 30 minutes (min) later. Group 3 was inhaled CO gas followed by 100 mg/kg magnesium sulphate intraperitoneally 30 min later. Group 2 and Group 3 rats was undergone laparotomy and craniotomy while still under anesthesia at 6 hour, and tissue sample was obtained from the cerebrum. Group 4 was inhaled CO gas followed by intraperitoneally normal saline 30 min later. Group 5 was inhaled CO gas followed by 100 mg/kg magnesium sulphate intraperitoneally 30 min later. Group 4 and Group 5 rats was undergone laparotomy and craniotomy while still under anesthesia at 24 hour, and tissue sample was obtained from the cerebrum. Nitric oxide levels were no significantly different between all groups. Malonyldialdehyde levels increased in intoxication group (group 2) and decreased in treatment group (group 3). Activities of superoxide dismutase decreased in intoxication group (group 2) and increased in treatment group (group 3). Activities of catalase increased in intoxication group (group 2) and decreased in treatment group (group 3). Activities of glutathione peroxidase (GSH-Px) decreased in intoxication group (group 4) and increased in treatment group (group 5). CO poisoning caused significant damage, detected within the first 6 hours. Due to antioxidant enzymes, especially GSH-Px activity reaching the top level within 24th hours, significant oxidative damage was not observed. The protective effect against oxidative damage of magnesium sulfate has been identified within the first 6 hours.

Ankle arthrodesis (AAD) and total ankle replacement (TAR) are the major surgical treatment options for severe ankle arthritis. There is an ongoing discussion in the orthopaedic community whether ankle arthrodesis or ankle fusion should be the treatment of choice for end stage osteoarthritis. The purpose of this study was to compare the participation in sports and recreational activities in patients who underwent either AAD or TAR for end-stage osteoarthritis of the ankle. A total of 41 patients (21 ankle arthrodesis /20 TAR) were examined at 34.5 (SD18.0) months after surgery. At follow-up, pre- and postoperative participation in sports and recreational activities has been assessed. Activity levels were determined using the ankle activity score according to Halasi et al. and the University of California at Los Angeles (UCLA) activity scale. Clinical and functional outcome was assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score. The percentage of patients participating in sports and recreational activities, UCLA score and AOFAS score were compared between both treatment groups. In the AAD group 86% were active in sports preoperatively and in the TAR group this number was 76%. Postoperatively in both groups 76% were active in sports (AAD, p = 0.08). The UCLA score was 7.0 (± 1.9) in the AAD group and 6.8 (± 1.8) in the TAR group (p = 0.78). The AOFAS score reached 75.6 (± 14) in the AAD group and 75.6 (± 16) in the TAR group (p = 0.97). The ankle activity score decrease was statistically significant for both groups (p = 0.047). Our study revealed no significant difference between the groups concerning activity levels, participation in sports activities, UCLA and AOFAS score. After AAD the number of patients participating in sports decreased. However, this change was not statistically significant.

The purpose of the present investigation was to evaluate whether pre-treatment neural activation in response to rewards is a predictor of clinical response to Behavioral Activation Therapy for Depression (BATD), an empirically validated psychotherapy that decreases depressive symptoms by increasing engagement with rewarding stimuli and reducing avoidance behaviors. Participants were 33 outpatients with major depressive disorder (MDD) and 20 matched controls. We examined group differences in activation, and the capacity to sustain activation, across task runs using functional magnetic resonance imaging (fMRI) and the monetary incentive delay (MID) task. Hierarchical linear modeling was used to investigate whether pre-treatment neural responses predicted change in depressive symptoms over the course of BATD treatment. MDD and Control groups differed in sustained activation during reward outcomes in the right nucleus accumbens, such that the MDD group experienced a significant decrease in activation in this region from the first to second task run relative to controls. Pretreatment anhedonia severity and pretreatment task-related reaction times were predictive of response to treatment. Furthermore, sustained activation in the anterior cingulate cortex during reward outcomes predicted response to psychotherapy; patients with greater sustained activation in this region were more responsive to BATD treatment. The current study only included a single treatment condition, thus it unknown whether these predictors of treatment response are specific to BATD or psychotherapy in general. Findings add to the growing body of literature suggesting that the capacity to sustain neural responses to rewards may be a critical endophenotype of MDD. Copyright © 2016 Elsevier B.V.

The present study evaluated the effects of Saccharomyces boulardii on duodenal digestive enzymes, morphology and cytokine induction response in broiler chicken. A total of 200 birds were allotted into two groups (n = 100) and each group divided into five replications (n = 20). The control group was fed basal diet in addition to antibiotic (virginiamycin 20 mg/kg), and treatment group received (1 × 10 8  colony-forming units/kg feed) S. boulardii in addition to basal diet lasting for 72 days. The results compared to control group revealed that adenosine triphosphatase, gamma glutamyl transpeptidase, lipase and trypsin activities were higher, while, no significant improvement was observed in amylase activities in the duodenum of the treatment group. Moreover, morphological findings showed that villus height, width and number of goblet cells markedly increased. Additionally, transmission electron microscopy visualized that villus height, width and structural condensation significantly increased in the treatment group. The immunohistological observations showed increased numbers of immunoglobulin A (IgA)-positive cells in the duodenum of the treatment group. Meanwhile, cytokine production levels of tumor necrosis factor-α, interleukin (IL)-10, transforming growth factor-β and secretory IgA markedly increased, and IL-6 statistically remained unchanged as compared to the control group. These findings illustrated that initial contact of S. boulardii to the duodenum has significant impact in improving enzymatic activity, intestinal morphology and cytokine response in broiler chicken. © 2016 Japanese Society of Animal Science.

To explore the comprehensive program of integrated Chinese and western medicine in the treatment of cognitive impairment in earthquake brain injury. The multi-central randomized controlled trial was adopted. The qualified subjects were randomized into an acupuncture + rehabilitation group (38 cases) and a rehabilitation group (35 cases). In the acupuncture + rehabilitation group, acupuncture, hyperbaric oxygen (HBO) and cognitive rehabilitation training were combined as the comprehensive program of integrated Chinese and western medicine in the treatment. In the rehabilitation group, HBO and cognitive rehabilitation training were adopted. The efficacy and safety were assessed. (1) After treatment of 2 months, the intelligent state, cognitive function and activity of daily life of patients were improved in the both groups (all P < 0.01). (2) After treatment of 2 months, the score of MMSE and the score of activity of daily life were (24.11 +/- 4.08) and (75.45 +/- 13.95) in the acupuncture + rehabilitation group, which were more significant as compared with (17.05 +/- 43.84), (66.06 +/- 12.75) in the rehabilitation group, respectively (both P < 0.01). In 6-month follow-up visit after treatment, the cognitive function and activity of daily life were improved continuously in the acupuncture + rehabilitation group, which was more significant as compared with the rehabilitation group (P < 0.01, P < 0.05). The integrated Chinese and western medicine of acupuncture, HBO and cognitive rehabilitation training is safe and effective in the treatment of cognitive impairment in earthquake brain injury. The therapeutic effect is more advantageous as compared with the simple rehabilitation program of western medicine.

The authors applied cognitive-behavioral therapy (CBT) for depression using the Healthy Management of Reality treatment manual. This 16-week group treatment comprised four 4-week modules: thoughts (cognitive restructuring), activities (behavioral activation), people (interpersonal skills training), and health (addresses physical health and depression). They illustrated the use of the culture-sensitive treatment manuals by way of the member characteristics and clinical process of a Spanish-language CBT group for depression. They highlighted the challenges and satisfactions of working with a Spanish-speaking population in the public sector, and focused on how culture and socioeconomic status influence patients, and how to adapt treatment to these factors. Last, they demonstrated how technological advances integrate with culture-sensitive, evidence-based treatments to better serve this population and reduce disparities. PMID:20549680

Cranial electrotherapy stimulation (CES) is reported to aid in relieving symptoms of depression and anxiety, though the mechanism underlying this effect remains unclear. Therefore, the present study aimed to evaluate changes in the hypothalamic-pituitary-adrenal (HPA) axis response and levels of neurotrophic factors, as well as changes in mood state, in patients undergoing CES therapy. Fifty healthy postmenopausal women were randomly assigned to either a Sham CES group (n = 25) or an Active CES group (n = 25). CES treatment was conducted in 20-minute sessions, three times per week for 8 weeks, using a micro current cranial electrotherapy stimulator. Blood samples were collected prior to and following the 8-week treatment period for measurement of cortisol, adrenocorticotropic hormone (ACTH), brain-derived neurotrophic factor (BDNF), and nerve growth factor (NGF) levels. Changes in mood state were also examined at the time of blood collection using the Profile of Mood States (POMS). No significant differences in cortisol, ACTH, BDNF, or NGF were observed between the two participant groups (p > 0.05) following the treatment period. However, those in the Active CES group exhibited significantly decreased Tension-Anxiety and Depression-Dejection scores on the POMS relative to pre-treatment scores (p < 0.05). Furthermore, Depression-Dejection scores following treatment were significantly lower in the Active CES group than in the Sham CES group (p < 0.05). No significant differences were observed in any other POMS scores such as Anger-Hostility, Vigor-Activity, Fatigue-Inertia, and Confusion-Bewilderment (p > 0.05). These results suggest that 8 weeks of CES treatment does not induce changes in blood levels of neurotrophic factors or HPA-axis-related hormones, though such treatment may be effective in treating symptoms of anxiety and depression.

d-Cycloserine (DCS) enhances extinction learning across species, but it has proven challenging to identify consistent benefit of DCS when added to therapeutic interventions. We conducted a placebo-controlled trial of DCS to potentiate social skills training in autism spectrum disorder (ASD) but found substantial improvement in both the DCS and placebo groups at the conclusion of active treatment. Here, we assess the impact of DCS 11 weeks following active treatment to evaluate the impact of DCS on treatment response durability. Study participants included 60 outpatient youth with ASD, ages 5-11 years, all with IQ above 70, and significantly impaired social functioning who completed a 10-week active treatment phase during which they received weekly single doses of 50 mg of DCS or placebo administered 30 min prior to group social skills training. Following the 10-week active treatment phase, blinded follow-up assessments occurred at week 11 and week 22. The primary outcome measure for our durability of treatment evaluation was the parent-rated social responsiveness scale (SRS) total raw score at week 22. Analysis of the SRS total raw score demonstrated significant decrease for the DCS group compared to the placebo group ( p  = 0.042) indicating greater maintenance of treatment effect in the DCS group. DCS was well tolerated, with irritability being the most frequently reported adverse effect in both groups. The findings of this study suggest that DCS may help youth with ASD to maintain skills gained during sort-term social skills training. Larger-scale studies with longer follow-up will be necessary to further understand the long-term impact of DCS paired with structured social skills training. ClinicalTrials.gov, NCT01086475.

Meta-analytic studies have not confirmed that involving parents in cognitive behavior therapy (CBT) for anxious children is therapeutically beneficial. There is also great heterogeneity in the type of parental involvement included. We investigated parental involvement focused on contingency management (CM) and transfer of control (TC) as a potential outcome moderator using a meta-analysis with individual patient data. Investigators of randomized controlled trials (RCTs) of CBT for anxious children, identified systematically, were invited to submit their data. Conditions in each RCT were coded based on type of parental involvement in CBT (i.e., low involvement, active involvement without emphasis on CM or TC, active involvement with emphasis on CM or TC). Treatment outcomes were compared using a 1-stage meta-analysis. All cases involved in active treatment (894 of 1,618) were included for subgroup analyses. Across all CBT groups, means of clinical severity, anxiety, and internalizing symptoms significantly decreased posttreatment and were comparable across groups. The group without emphasis on CM or TC showed a higher proportion with posttreatment anxiety diagnoses than the low-involvement group. Between posttreatment and 1-year follow-up, the proportion with anxiety diagnoses significantly decreased in CBT with active parental involvement with emphasis on CM or TC, whereas treatment gains were merely maintained in the other 2 groups. CBT for anxious children is an effective treatment with or without active parental involvement. However, CBT with active parental involvement emphasizing CM or TC may support long-term maintenance of treatment gains. RESULTS should be replicated as additional RCTs are published.

The state of the art for treatment efficacy studies now requires manual guided treatments and tests of therapist adherence. This report provides findings regarding adherence assessment of therapists participating in an investigation of treatment matching in adolescent substance abusers. The Group Sessions Rating Scale (GSRS), a group-therapy process measure, was studied to determine its appropriateness for assessing group treatment of adolescents with a) substance use disorders (SUD), b) interrater reliability, c) internal consistency, and d) ability to discriminate the active ingredients of cognitive-behavioral therapy (CBT) from interactional therapy (IT). Interrater reliabilities were moderate to high, with those for CBT generally higher than those for IT. Internal consistency of CBT items was moderate, whereas those of IT were moderately high. Discriminability between the two treatment modalities was high. The frequency of active ingredients was generally therapy-specific: high for the relevant and low for the nonrelevant therapeutic modality items. The GSRS was found to be effective in the measurement of treatment process in adolescents with SUD.

There is limited evidence supporting use of physical therapy for hip osteoarthritis. To determine efficacy of physical therapy on pain and physical function in patients with hip osteoarthritis. Randomized, placebo-controlled, participant- and assessor-blinded trial involving 102 community volunteers with hip pain levels of 40 or higher on a visual analog scale of 100 mm (range, 0-100 mm; 100 indicates worst pain possible) and hip osteoarthritis confirmed by radiograph. Forty-nine patients in the active group and 53 in the sham group underwent 12 weeks of intervention and 24 weeks of follow-up (May 2010-February 2013) INTERVENTIONS: Participants attended 10 treatment sessions over 12 weeks. Active treatment included education and advice, manual therapy, home exercise, and gait aid if appropriate. Sham treatment included inactive ultrasound and inert gel. For 24 weeks after treatment, the active group continued unsupervised home exercise while the sham group self-applied gel 3 times weekly. Primary outcomes were average pain (0 mm, no pain; 100 mm, worst pain possible) and physical function (Western Ontario and McMaster Universities Osteoarthritis Index, 0 no difficulty to 68 extreme difficulty) at week 13. Secondary outcomes were these measures at week 36 and impairments, physical performance, global change, psychological status, and quality of life at weeks 13 and 36. Ninety-six patients (94%) completed week 13 measurements and 83 (81%) completed week 36 measurements. The between-group differences for improvements in pain were not significant. For the active group, the baseline mean (SD) visual analog scale score was 58.8 mm (13.3) and the week-13 score was 40.1 mm (24.6); for the sham group, the baseline score was 58.0 mm (11.6) and the week-13 score was 35.2 mm (21.4). The mean difference was 6.9 mm favoring sham treatment (95% CI, -3.9 to 17.7). The function scores were not significantly different between groups. The baseline mean (SD) physical function score for the active group was 32.3 (9.2) and the week-13 score was 27.5 (12.9) units, whereas the baseline score for the sham treatment group was 32.4 (8.4) units and the week-13 score was 26.4 (11.3) units, for a mean difference of 1.4 units favoring sham (95% CI, -3.8 to 6.5) at week 13. There were no between-group differences in secondary outcomes (except greater week-13 improvement in the balance step test in the active group). Nineteen of 46 patients (41%) in the active group reported 26 mild adverse effects and 7 of 49 (14%) in the sham group reported 9 mild adverse events (P = .003). Among adults with painful hip osteoarthritis, physical therapy did not result in greater improvement in pain or function compared with sham treatment, raising questions about its value for these patients. anzctr.org.au Identifier: ACTRN12610000439044.

Physical activity has been shown to be effective in the treatment of conditions, such as fibromyalgia and depression. Although these conditions are associated with irritable bowel syndrome (IBS), no study has assessed the effect of physical activity on gastrointestinal (GI) symptoms in IBS. The aim was to study the effect of physical activity on symptoms in IBS. We randomized 102 patients to a physical activity group and a control group. Patients of the physical activity group were instructed by a physiotherapist to increase their physical activity, and those of the control group were instructed to maintain their lifestyle. The primary end point was to assess the change in the IBS Severity Scoring System (IBS-SSS). A total of 38 (73.7% women, median age 38.5 (19-65) years) patients in the control group and 37 (75.7% women, median age 36 (18-65) years) patients in the physical activity group completed the study. There was a significant difference in the improvement in the IBS-SSS score between the physical activity group and the control group (-51 (-130 and 49) vs. -5 (-101 and 118), P=0.003). The proportion of patients with increased IBS symptom severity during the study was significantly larger in the control group than in the physical activity group. Increased physical activity improves GI symptoms in IBS. Physically active patients with IBS will face less symptom deterioration compared with physically inactive patients. Physical activity should be used as a primary treatment modality in IBS.

The aim of this study was to evaluate the safety and efficacy of an individualized steroid regimen in patients with moderate-to-severe Graves' orbitopathy (GO) by monitoring clinical and imaging parameters. In total, 47 patients with active, moderate-to-severe GO were enrolled in this study. All the patients received the proposed treatment regimen by European Group on GO of 4.5 g of intravenous (IV) methylprednisolone for 12 weeks. At the end of the IV treatment, patients with persistent active GO (Group 1) who were assessed by clinical examination and orbital imaging with short tau inversion recovery-sequence magnetic resonance imaging (STIR MRI) received additional treatment with oral prednisolone, and those with inactive GO (Group 2) received no further treatment. Of the 42 patients who completed the study, 22 (52.4%) patients formed Group 1 and 20 (47.6%) patients Group 2. At the 12th week, the overall response to IV treatment was 76.2%, and clinical activity score (CAS) improvement was 69%. At the 24th week, the overall response was 92.8%, and CAS improvement was 97.6%, without statistically significant difference in CAS and total eye score between these two groups ( P =0.157 and P =0.856, respectively). Ophthalmic manifestations were improved, being absent or minimal in 78.6% of patients at the 24th week follow-up. Recurrence of disease activity occurred in 9.5% of patients up to 24 weeks after the completion of treatment, and major adverse events occurred in 6.4% of patients. In patients with moderate-to-severe GO, IV steroid treatment, followed by oral treatment, when needed, is an effective regimen with low rates of adverse events and recurrences. STIR MRI is a significant tool for recognizing patients who need additional steroid treatment.

Several studies on avoidance of house-dust-mite (HDM) and cat allergens have been carried out, most of them in asthmatic patients and only a few in patients with atopic dermatitis (AD). No study so far has focused on which subgroup of AD patients benefits from avoidance measures. Forty adult patients with AD completed the 12-month avoidance study. They were divided into an active treatment (n = 22) and a placebo (n = 18) group. Active treatment comprised use of polyurethane-coated cotton encasings for bedding, and placebo use of cotton covers. Patients came for regular checkups during the 12-month period, when eczema severity was assessed and blood samples were analyzed for total IgE, HDM- and cat-specific IgE and soluble CD30 (sCD30) in serum. Dust samples were collected from mattresses before treatment and after 3, 6, and 12 months, and analyzed for content of HDM and cat allergen. Eczema severity decreased significantly in both groups (P < 0.001), with a more pronounced decrease in patients with active covers. The HDM exposure decreased significantly in the active treatment group (P < 0.001), and the levels of HDM-specific IgE were reduced (P<0.05). Exposure to cat allergens was unchanged in the active treatment group but decreased, albeit not significantly (P=0.19), in the placebo group. sCD30 levels were significantly reduced in both groups (P<0.001). Patients not sensitized to HDM allergens benefited from the bedcovers as much as sensitized patients. Occlusive bedding significantly reduced HDM exposure in bed (P<0.001) and eczema severity, and sCD30 levels decreased significantly (P<0.001). Patients not sensitized to HDM and not exposed to HDM allergens benefited equally from use of the bedcovers, a result which could be due to a reduction of other important allergens, superantigens, or irritants in bed. We therefore recommend the use of bedcovers as part of treatment for AD.

Bone morphogenetic protein (BMP) appears to be one of the most promising cytokine and for clinical use in reconstructive surgery for bony defects and augmentation. To evaluate the effect of basic fibroblast growth factor (bFGF), FK506, elcatonin, and hyperbaric oxygenation (HBO) on osteoinduction by recombinant human bone morphogenetic protein-2 (rhBMP-2), 2 or 5 μg of rhBMP-2 was implanted into intramuscular sites of rats. At 21 days after implantation, the osteoinductive activity in the treatment group and control group was compared radiographically, biochemically, and histologically. The amount of new bone in the treatment group was significantly greater than that in the control group. The alkaline phosphatase activity and calcium content in the treatment group were significantly higher than those in the control group. These results suggest that bFGF, FK506, elcatonin, and HBO accelerated the activity and rate of osteoinduction by rhBMP2. These results may be useful when BMP is applied clinically in near future.

Background Cognitive problems in breast cancer patients are common after systemic treatment, particularly chemotherapy. An increasing number of fMRI studies show altered brain activation in breast cancer patients after treatment, suggestive of neurotoxicity. Previous prospective fMRI studies administered a single cognitive task. The current study employed two task paradigms to evaluate whether treatment-induced changes depend on the probed cognitive domain. Methods Participants were breast cancer patients scheduled to receive systemic treatment (anthracycline-based chemotherapy +/- endocrine treatment, n = 28), or no systemic treatment (n = 24) and no-cancer controls (n = 31). Assessment took place before adjuvant treatment and six months after chemotherapy, or at similar intervals. Blood oxygen level dependent (BOLD) activation and performance were measured during an executive functioning task and an episodic memory task. Group-by-time interactions were analyzed using a flexible factorial design. Results Task performance did not differ between patient groups and did not change over time. Breast cancer patients who received systemic treatment, however, showed increased parietal activation compared to baseline with increasing executive functioning task load compared to breast cancer patients who did not receive systemic treatment. This hyperactivation was accompanied by worse physical functioning, higher levels of fatigue and more cognitive complaints. In contrast, in breast cancer patients who did not receive systemic treatment, parietal activation normalized over time compared to the other two groups. Conclusions Parietal hyperactivation after systemic treatment in the context of stable levels of executive task performance is compatible with a compensatory processing account of hyperactivation or maintain adequate performance levels. This over-recruitment of brain regions depends on the probed cognitive domain and may represent a response to decreased neural integrity after systemic treatment. Overall these results suggest different neurobehavioral trajectories in breast cancer patients depending on treatment type. PMID:28267750

BACKGROUND Tight control of severe rheumatoid arthritis (RA) in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA) in patients undergoing switching of biologics. We performed this retrospective case–control study to investigate the efficacy of achieving an immediate treatment response using the K-method. METHODS This study involved 20 patients with RA (control group, 10 patients; K-method group, 10 patients). Patients in the control group were switched to golimumab from other biologics without intra-articular injection of TA. The K-method involved injection of 1 mL of TA (40 mg/mL) and 2 mL of 1% lidocaine hydrochloride into swollen or painful joints on the same day as golimumab treatment. A quick response one day after treatment was compared between the two groups according to the disease activity score 28 based on C-reactive protein (DAS28 CRP), clinical disease activity index (CDAI), simplified disease activity index (SDAI), European League Against Rheumatism (EULAR) response, and remission rate. These parameters were investigated for 24 weeks. RESULTS The K-method group showed significant improvements in DAS28 CRP, CDAI, and SDAI at one day, 12 weeks, and 24 weeks compared with the control group. The number of swollen and tender joints and the patient and doctor global visual analog scale scores were also significantly different between the two groups. The remission rates based on DAS28 CRP were 30% at one day, 50% at 12 weeks, and 60% at 24 weeks in the K-method group. The EULAR good/moderate response rates were 80% at one day, 90% at 12 weeks, and 90% at 24 weeks in the K-method group; however, these rates were only 10%, 40%, and 40%, respectively, in the control group. No adverse events occurred in either group. CONCLUSION Simultaneous treatment with biologics and intra-articular injection of TA is useful for cases involving switching of biologics for RA. This strategy is safe and practical for RA treatment. PMID:27081319

Background A software based tool has been developed (Optem) to allow automatize the recommendations of the Canadian Multiple Sclerosis Working Group for optimizing MS treatment in order to avoid subjective interpretation. Methods Treatment Optimization Recommendations (TORs) were applied to our database of patients treated with IFN β1a IM. Patient data were assessed during year 1 for disease activity, and patients were assigned to 2 groups according to TOR: "change treatment" (CH) and "no change treatment" (NCH). These assessments were then compared to observed clinical outcomes for disease activity over the following years. Results We have data on 55 patients. The "change treatment" status was assigned to 22 patients, and "no change treatment" to 33 patients. The estimated sensitivity and specificity according to last visit status were 73.9% and 84.4%. During the following years, the Relapse Rate was always higher in the "change treatment" group than in the "no change treatment" group (5 y; CH: 0.7, NCH: 0.07; p < 0.001, 12 m – last visit; CH: 0.536, NCH: 0.34). We obtained the same results with the EDSS (4 y; CH: 3.53, NCH: 2.55, annual progression rate in 12 m – last visit; CH: 0.29, NCH: 0.13). Conclusion Applying TOR at the first year of therapy allowed accurate prediction of continued disease activity in relapses and disability progression. PMID:18325088

To compare the effects of 1) active group music therapy and 2) receptive group music therapy to group counseling in treatment of major depressive disorder (MDD). On top of standard care, 14 MDD outpatients were randomly assigned to receive 1) active group music therapy (n=5), 2) receptive group music therapy (n=5), or 3) group counseling (n=4). There were 12 one-hour weekly group sessions in each arm. Participants were assessed at baseline, 1 month (after 4 sessions), 3 months (end of interventions), and 6 months. Primary outcomes were depressive scores measured by Montgomery-Åsberg Depression Rating Scale (MADRS) Thai version. Secondary outcomes were self-rated depression score and quality of life. At 1 month, 3 months, and 6 months, both therapy groups showed statistically non-significant reduction in MADRS Thai scores when compared with the control group (group counseling). The reduction was slightly greater in the active group than the receptive group. Although there were trend toward better outcomes on self-report depression and quality of life, the differences were not statistically significant. Group music therapy, either active or receptive, is an interesting adjunctive treatment option for outpatients with MDD. The receptive group may reach peak therapeutic effect faster, but the active group may have higher peak effect. Group music therapy deserves further comprehensive studies.

This study evaluates the effect of incobotulinumtoxinA in the acute and chronic phases of facial nerve palsy after neurosurgical interventions. Patients received incobotulinumtoxinA injections (active treatment group) or standard rehabilitation treatment (control group). Functional efficacy was assessed using House-Brackmann, Yanagihara System and Sunnybrook Facial Grading scales, and Facial Disability Index self-assessment. Significant improvements on all scales were seen after 1month of incobotulinumtoxinA treatment (active treatment group, р<0.05), but only after 3months of rehabilitation treatment (control group, р<0.05). At 1 and 2years post-surgery, the prevalence of synkinesis was significantly higher in patients in the control group compared with those receiving incobotulinumtoxinA treatment (р<0.05 and р<0.001, respectively). IncobotulinumtoxinA treatment resulted in significant improvements in facial symmetry in patients with facial nerve injury following neurosurgical interventions. Treatment was effective for the correction of the compensatory hyperactivity of mimic muscles on the unaffected side that develops in the acute period of facial nerve palsy, and for the correction of synkinesis in the affected side that develops in the long-term period. Appropriate dosing and patient education to perform exercises to restore mimic muscle function should be considered in multimodal treatment. Copyright © 2017 Elsevier B.V. All rights reserved.

Ankaferd Blood Stopper (ABS) is a new promising local hemostatic agent, and its mechanism on hemostasis has been shown by many studies. However, the effects of ABS on skin superoxide dismutase (SOD) and catalase (CAT) activities have not been investigated before. The aim of this study was to evaluate the effects of this new generation local hemostatic agent on warfarin-treated rats focusing on its the antioxidant potential in short-term soft tissue healing. Twelve systemically warfarin treated (warfarin group) and 12 none treated Wistar Albino rats (control group) were selected for the trial. Rats in the warfarin group were treated intraperitonally with 0.1 mg/kg warfarin, and rats in the control group were given 1 mL/kg saline 3 days earlier to surgical procedure and continued until killing. All rats had incisions on dorsal dermal tissue, which was applied ABS or no hemostatic agent before suturing. Six of each group were killed on day 4, and the other 6 were killed on day 8. Blood and skin samples were taken. Prothrombin time (PT) in blood samples, CAT, and SOD activities in skin samples were determined. Warfarin treatment dose was found to be convenient and warfarin treatment increased the PT levels as expected. Warfarin treatment decreased CAT activity significantly compared to the control group. The ABS treatment significantly increased SOD activities in the warfarin group at the end of the eighth day. Ankaferd Blood Stopper acted positively in short-term tissue healing by increasing SOD activity in warfarin-treated rats. Therefore, ABS may be suggeted as a promoting factor in tissue healing.

Broiler eggs were either incubated at 37.8°C during the whole incubation period (control), or at higher (38.8°C, group H) and lower temperatures (36.8°C, group L) from embryonic day (ED) 7 up to ED 10 (ED 7 to 10) or from ED 10 up to ED 13 (ED 10 to 13). Before and after this temperature treatment the eggs were incubated at 37.8°C. The day-old chicks were weighted, sexed and fed up to day 35. On days 1 and 35 samples were taken from the breast and leg muscles for analyzing of the mitochondrial respiratory activity (MRA) and from the breast muscles for analysis of the cross-sectional areas (CSA) and the glycogen phosphorylase (GP), phosphofructokinase (PFK), lactate dehydrogenase (LDH), citrate synthase (CS) and cytochrome oxidase (COX) activities. Statistical analysis showed that treatment (control, group H, group L), sex and their interaction, but not the treatment period (ED 7 to 10; ED 10 to 13), significantly influenced the results. Group H chicks had lower (P⩽0.05) body and heart weights but higher (P⩽0.05) liver weights, CSA values, leg MRA as well as PFK, LDH, CS, GP and COX activities compared with the group L chicks. The results of the control chicks differ (P⩽0.05) from those of the group H (body, heart weight, COX), the group L chicks (liver weight, PFK, LDH, CS, GP) or the birds of both other groups (CSA). The group H broiler had higher (P⩽0.05) body and leg weights as well as LDH, CS, COX and GP activities than the group L broilers. The BWs and the LDH and GP results of the control broiler differ (P⩽0.05) from those of both other groups or from the results of the group H (CS) and group L broiler (COX). Female broilers had lower (P⩽0.05) body, breast and leg weights, but higher (P⩽0.05) CSA, LDH, CS and GP activities than the male animals. Analysis of treatment×sex interaction showed that group H hens had higher (P⩽0.05) body and breast weights, LDH and GP activities compared with the group L hens, whereas in the male broiler no effect of the interaction could be found, except for the lower (P⩽0.05) CSA values in the group H than group L cocks. The treatment effects are probably due to altered embryonic activity and related molecular mechanisms. The sex-related differences in the broiler indicate that these alterations already occur in the embryos and chicks, but become significant with the sexual dimorphism after hatch.

A virtual pet was developed based on the framework of the youth physical activity promotion model and tested as a vehicle for promoting physical activity in children. Children in the treatment group interacted with the virtual pet for three days, setting physical activity goals and teaching tricks to the virtual pet when their goals were met. The virtual pet became more fit and learned more sophisticated tricks as the children achieved activity goals. Children in the control group interacted with a computer system presenting equivalent features but without the virtual pet. Physical activity and goal attainment were evaluated using activity monitors. Results indicated that children in the treatment group engaged in 1.09 more hours of daily physical activity (156% more) than did those in the control group. Physical activity self-efficacy and beliefs served as mediators driving this increase in activity. Children that interacted with the virtual pet also expressed higher intentions than children in the control group to continue physical activity in the future. Theoretical and practical potentials of using a virtual pet to systematically promote physical activity in children are discussed.

To observe the impacts of acupuncture of reinforcing kidney and activating spleen on the excretion of urinary fluoride and pain of the patients with drinking-water type fluorosis. The randomized controlled and single-blind trial was adopted. Seventy-two cases were randomized into an observation group and a control group, 36 cases in each one. In the observation group, acupuncture was applied at Pishu (BL 20), Shenshu (BL 23), Guanyuan (CV 4), Zusanli (ST 36), etc. , three treatments a week. In the control group, the Calcium Carbonate D3 tablets were prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months. The changes of the content of urinary fluoride and pain score (by VAS) before and after treatment between two groups were compared. The urinary fluoride excretion was increased obviously after treatment in the observation group (P < 0.01), which was superior apparently to that in the control group [(11.06 +/- 4.54) mg/L vs. (8.30 +/- 4.14) mg/L, P < 0.05]. After treatment, VAS score was reduced significantly in either group (both P < 0.01). The result in the observation group was lower remarkably than that in the control group (1.93 +/- 1.30 vs. 3.47 +/- 2.29, P < 0.01). Acupuncture achieves the significant efficacy on the promotion of urinary fluoride excretion and pain relieving of the patients with drinking-water type fluorosis in light of reinforcing kidney and activating spleen, which is superior to the oral administration of the calcium carbonate D3 tablets.

Active ingredients of substance use-focused self-help groups.

PubMed

Moos, Rudolf H

2008-03-01

This paper provides an overview of some of the probable active ingredients of self-help groups in light of four related theories that identify common social processes that appear to underlie effective psychosocial treatments for and continuing remission from these disorders. Social control theory specifies active ingredients such as bonding, goal direction and structure; social learning theory specifies the importance of norms and role models, behavioral economics and behavioral choice theory emphasizes involvement in rewarding activities other than substance use, and stress and coping theory highlights building self-efficacy and effective coping skills. A review of existing studies suggests that the emphasis on these active ingredients probably underlies some aspects of the effectiveness of self-help groups. Several issues that need to be addressed to enhance understanding of the active ingredients of action of self-help groups are discussed, including consideration of indices of Alcoholics Anonymous (AA) affiliation as active ingredients, identification of personal characteristics that may moderate the influence of active ingredients on substance use outcomes, examination of whether active ingredients of self-help groups, can amplify or compensate for treatment, identification of potential detrimental effects of involvement in self-help groups and focusing on the link between active ingredients of self-help groups and other aspects of the overall recovery milieu, such as the family and social networks.

Objective HIV-infected older adults (HOA) are at risk of functional decline. Interventions promoting physical activity that can attenuate functional decline and are easily translated into the HOA community are of high priority. We conducted a randomized, controlled clinical trial to evaluate whether a physical activity counseling intervention based on self-determination theory (SDT) improves physical function, autonomous motivation, depression and the quality of life (QOL) in HOA. Methods A total of 67 community-dwelling HOA with mild-to-moderate functional limitations were randomized to one of two groups: a physical activity counseling group or the usual care control group. We used SDT to guide the development of the experimental intervention. Outcome measures that were collected at baseline and final study visits included a battery of physical function tests, levels of physical activity, autonomous motivation, depression, and QOL. Results The study participants were similar in their demographic and clinical characteristics in both the treatment and control groups. Overall physical performance, gait speed, measures of endurance and strength, and levels of physical activity improved in the treatment group compared to the control group (p<0.05). Measures of autonomous regulation such as identified regulation, and measures of depression and QOL improved significantly in the treatment group compared to the control group (p<0.05). Across the groups, improvement in intrinsic regulation and QOL correlated with an improvement in physical function (p<0.05). Conclusion Our findings suggest that a physical activity counseling program grounded in SDT can improve physical function, autonomous motivation, depression, and QOL in HOA with functional limitations.

2013-01-01

Objective This study explored the automatic and controlled processes that may influence performance on an implicit measure across cognitive-behavioral group therapy for panic disorder. Method The Quadruple Process model was applied to error scores from an Implicit Association Test evaluating associations between the concepts Me (vs. Not Me) + Calm (vs. Panicked) to evaluate four distinct processes: Association Activation, Detection, Guessing, and Overcoming Bias. Parameter estimates were calculated in the panic group (n=28) across each treatment session where the IAT was administered, and at matched times when the IAT was completed in the healthy control group (n=31). Results Association Activation for Me + Calm became stronger over treatment for participants in the panic group, demonstrating that it is possible to change automatically activated associations in memory (vs. simply overriding those associations) in a clinical sample via therapy. As well, the Guessing bias toward the calm category increased over treatment for participants in the panic group. Conclusions This research evaluates key tenets about the role of automatic processing in cognitive models of anxiety, and emphasizes the viability of changing the actual activation of automatic associations in the context of treatment, versus only changing a person’s ability to use reflective processing to overcome biased automatic processing.

The purpose of the present study was to evaluate the possible therapeutic effects and the safety of Mangifera indica extract (Vimang tablets, 300 mg) combined with methotrexate (MTX) on reducing disease activity in rheumatoid arthritis (RA). Twenty patients with active RA underwent a year of treatment with MTX (12.5 mg/week) associated to non-steroidal anti-inflammatory drugs (NSAIDs) and/or prednisone (5-10 mg/day) were randomly allocated to the experimental group (n=10), that received the extract supplementation (900 mg/day) or preceding usual treatment (n=10) during 180 days. RA activity was evaluated using the tender and swollen joint counts, erythrocyte sedimentation rate, disease activity score-28 (DAS 28), visual analogue scale (VAS) and health assessment questionnaire (HAQ). Treatment's efficacy was demonstrated with ACR criteria. Only the patients of MTX-Vimang group revealed statistically significant improvement in DAS 28 parameters with respect baseline data but no differences were observed between groups. ACR improvements amounted 80% only in MTX-Vimang group at the 90 days (p<0.001). In MTX-Vimang group, 100% of patients decreased NSAIDs administration (p<0.01) and 70% of those eradicated gastrointestinal side effects (p<0.01) ensuing of the preceding treatment. Other adverse effects were not reported. Copyright © 2013 John Wiley & Sons, Ltd.

To explore the effectiveness of acupressure and Montessori-based activities in decreasing the agitated behaviors of residents with dementia. A double-blinded, randomized (two treatments and one control; three time periods) cross-over design was used. Six special care units for residents with dementia in long-term care facilities in Taiwan were the sites for the study. One hundred thirty-three institutionalized residents with dementia. Subjects were randomized into three treatment sequences: acupressure-presence-Montessori methods, Montessori methods-acupressure-presence and presence-Montessori methods-acupressure. All treatments were done once a day, 6 days per week, for a 4-week period. The Cohen-Mansfield Agitation Inventory, Ease-of-Care, and the Apparent Affect Rating Scale. After receiving the intervention, the acupressure and Montessori-based-activities groups saw a significant decrease in agitated behaviors, aggressive behaviors, and physically nonaggressive behaviors than the presence group. Additionally, the ease-of-care ratings for the acupressure and Montessori-based-activities groups were significantly better than for the presence group. In terms of apparent affect, positive affect in the Montessori-based-activities group was significantly better than in the presence group. This study confirms that a blending of traditional Chinese medicine and a Western activities program would be useful in elderly care and that in-service training for formal caregivers in the use of these interventions would be beneficial for patients

Background: Therapeutic goal in patients with cleft lip and palate is esthetics and long-term health of the stomatognathic system. Patients with cleft lip and palate routinely require extensive and prolonged orthodontic treatment. The osseous structures are absent or poorly developed in the osseous clefts and may be traumatized in the course of orthodontic therapy; hence require constant monitoring during orthodontic treatment. The aim of the study was to evaluate the tissue response of cleft palate patients by quantitative analysis of enzyme activity during orthodontic treatment and assess any difference in the tissue response with that of noncleft patients undergoing orthodontic treatment. Materials and Methods: 20 patients requiring orthodontic treatment agedbetween 15 to 25 years were included to participate in the studyof which ten were cleft palate patients (group I) and ten noncleft patients (group II). The GCF samples were collected at incisor and molar sites during orthodontic treatment on days as per the study design in both the groups. The GCF enzymatic levels were estimated and compared. Results: Both groups showed significant increased enzyme activity at the incisor site compared to molar site corresponding to the phases of tooth movement. Conclusion: There was significant difference in enzyme activity between the incisor adjacent to the cleft site and molar site. There was no difference in the tissue response between cleft palate patients and noncleft patients during orthodontic treatment. PMID:24049331

Cutaneous leishmaniasis is a zoonosis caused by protozoa of the genus Leishmania. Conventional treatments are long and aggressive, and they trigger a diversity of side effects. Photodynamic Therapy was originally proposed as a treatment for cancer, and it now appears to be a promising therapy for local treatment with fewer side effects of infectious diseases. This study aimed to evaluate Chlorin e6 internalization by Leishmania major and Leishmania braziliensis promastigotes and its viability and effects on mitochondrial activity. Control groups were kept in the dark, while PDT groups received fluence of 10J/cm(2) (660nm). Chlorin internalization was evaluated using confocal microscopy after one hour of incubation for both species. The mitochondrial activity was evaluated by MTT assay, and viability was measured by the Trypan blue exclusion test. Giemsa staining was used to observe morphological changes. PS was internalized in both species and mitochondrial activity changed in all groups. However, the obtained MTT and Trypan results indicated that despite the change in mitochondrial activity in the dark groups, their viability was not affected, whereas the PDT treated groups had significantly reduced viability. Morphology was drastically altered in PDT treated groups, while groups kept in the dark exhibited the standard morphology. This study demonstrates that Chlorin has great potential for being used in PDT as a treatment for cutaneous leishmaniasis, although more studies are needed to determine in vivo application protocols.

N-butyldeoxynojirimycin treatment restores the innate fear response and improves learning in mucopolysaccharidosis IIIA mice.

PubMed

Kaidonis, Xenia; Byers, Sharon; Ranieri, Enzo; Sharp, Peter; Fletcher, Janice; Derrick-Roberts, Ainslie

2016-06-01

Mucopolysaccharidosis IIIA is a heritable neurodegenerative disorder resulting from the dysfunction of the lysosomal hydrolase sulphamidase. This leads to the primary accumulation of the complex carbohydrate heparan sulphate in a wide range of tissues and the secondary neuronal storage of gangliosides GM2 and GM3 in the brain. GM2 storage is associated with CNS deterioration in the GM2 gangliosidosis group of lysosomal storage disorders and may also contribute to MPS CNS disease. N-butyldeoxynojirimycin, an inhibitor of ceramide glucosyltransferase activity and therefore of ganglioside synthesis, was administered to MPS IIIA mice both prior to maximal GM2 and GM3 accumulation (early treatment) and after the maximum level of ganglioside had accumulated in the brain (late treatment) to determine if behaviour was altered by ganglioside level. Ceramide glucosyltransferase activity was decreased in both treatment groups; however, brain ganglioside levels were only decreased in the late treatment group. Learning in the water cross maze was improved in both groups and the innate fear response was also restored in both groups. A reduction in the expression of inflammatory gene Ccl3 was observed in the early treatment group, while IL1β expression was reduced in both treatment groups. Thus, it appears that NB-DNJ elicits a transient decrease in brain ganglioside levels, some modulation of inflammatory cytokines and a functional improvement in behaviour that can be elicited both before and after overt neurological changes manifest. NB-DNJ improves learning and restores the innate fear response in MPS IIIA mice by decreasing ceramide glucosyltransferase activity and transiently reducing ganglioside storage and/or modulating inflammatory signals.

The effective treatment of depression has been reported to reduce the severity of alcohol use, potentially reflecting improvements in common brain reward circuits. We hypothesized that augmentation therapy of escitalopram with aripiprazole would improve depressive symptoms as well as reduce craving for alcohol and cue-induced brain activity in patients with co-morbid alcohol dependence and major depressive disorder, compared with treatment with escitalopram alone. Thirty-five subjects with major depressive disorder and alcohol dependence were recruited and randomly assigned into 17 aripiprazole + escitalopram and 18 escitalopram only groups. At baseline and following six weeks of treatment, symptoms of depression, craving for alcohol and brain activity were evaluated. During the six week treatment period, Beck Depression Inventory and clinical global index-severity (CGI-S) scores decreased in both the aripiprazole + escitalopram and escitalopram only groups. In addition, following the treatment period, the Korean alcohol urge questionnaire scores in the aripiprazole + escitalopram group were reduced from 23.3±8.4 to 14.3±4.9, compared with those of the escitalopram group of from 21.6±8.4 to 19.3±7.1 (F=13.1, p<0.01). The activity within the anterior cingulate was increased in response to the presentation of alcohol drinking scenes following treatment in the aripiprazole + escitalopram group. The change of brain activity within the left anterior cingulate gyrus in all patients with co-morbid alcohol dependence and major depressive disorder was negatively correlated with the change in craving for alcohol. These findings suggest that the effects of aripiprazole on anterior cingulate cortex might mediate the successful treatment of alcohol dependence in patients with major depressive disorder.

Behavioral activation-based guided self-help treatment administered through a smartphone application: study protocol for a randomized controlled trial

PubMed Central

2012-01-01

Background The need for cost-effective interventions for people suffering from major depressive disorders is essential. Behavioral activation is an intervention that can largely benefit from the use of new mobile technologies (for example smartphones). Therefore, developing smartphone-based behavioral activation interventions might be a way to develop cost-effective treatments for people suffering from major depressive disorders. The aim of this study will be to test the effects of a smartphone-delivered behavioral activation treatment. Methods The study will be a randomized controlled trial with a sample size of 120 participants, with 60 patients in each group. The treatment group includes an 8-week smartphone-based behavioral activation intervention, with minimal therapist contact. The smartphone-based intervention consists of a web-based psychoeducation, and a smartphone application. There is also a back-end system where the therapist can see reports from the patients or activities being reported. In the attention control group, we will include brief online education and then recommend use of a smartphone application that is not directly aimed at depression (for example, ‘Effective meditation’). The duration of the control condition will also be 8 weeks. For ethical reasons we will give the participants in the control group access to the behavioral activation treatment following the 8-week treatment period. Discussions We believe that this trial has at least three important implications. First, we believe that smartphones can be integrated even further into society and therefore may serve an important role in health care. Second, while behavioral activation is a psychological treatment approach for which there is empirical support, the use of a smartphone application could serve as the therapist’s prolonged arm into the daily life of the patient. Third, as we have been doing trials on guided Internet treatment for more than 10 years it is now time to move to the next generation of information technology - smartphones - which are not only relevant for Swedish conditions but also for developing countries in the world which are increasingly empowered by mobile phones with Internet connection.

Acute lung injury (ALI) is a common component of systemic inflammatory disease without more effective treatments. However, recent studies have demonstrated that the recombinant human brain natriuretic peptide (rhBNP) has anti-inflammatory effects. Therefore, we found that rhBNP could prevent lipopolysaccharide (LPS)-induced acute lung injury in a dog model. Dogs were injected with LPS and subjected to continuous intravenous infusion (CIV) of saline solution or rhBNP. We detected the protective effects of rhBNP by histological examination and determination of serum cytokine levels and lung myeloperoxidase (MPO) activity and malondialdehyde (MDA) activity. Histological examination indicated marked inflammation, edema and hemorrhage in lung tissue taken 12h after rhBNP treatment compared with tissue from dogs which received saline treatment after LPS injection. LPS injection induced cytokine (IL-6 and TNF-α) secretion and lung MPO and MDA activities, which were also attenuated by rhBNP treatment. Inductions of IL-6 and TNF-α were significantly attenuated in the L-rhBNP and the H-rhBNP groups. The ratios of the L-rhBNP group and H-rhBNP group were lower than that in the lung injury group. Furthermore, MPO and MDA activities were significantly lower in the H-rhBNP group compared to those in the LI group. Our data indicate that rhBNP treatment may exert protective effects and may be associated with adjusting endogenous antioxidant enzymes. Thus, rhBNP may be considered as a therapeutic agent for various clinical conditions involving lung injury by sepsis. Copyright © 2013 Elsevier B.V. All rights reserved.

Based on the western medication, to evaluate the advantages in the morning blood pressure treated with acupuncture at Fengchi (GB 20) and Neck-Jiaji (EX-B 2) combined with acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen in the patients with essential hypertension. A total of 90 patients of essential hypertension of the mild and moderate degrees were randomized into a medication group (30 cases, 3 dropping), No.1 acupuncture group (30 cases, 2 dropping) and No.2 acupuncture group (30 cases, 1 dropping). In the medication group, adalat was prescribed for oral administration, 30 mg at 7 am every day, continuously for 6 weeks. In the No.1 acupuncture group, on the basis of the treatment as the medication group, the acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen was applied and the acupoints were Renying (ST 9), Hegu (LI 4), Taichong (LR 3), Quchi (LI 11) and Zusanli (ST 36). In the No.2 acupuncture group, on the basis of the treatment as the No.1 acupuncture group, Fengchi (GB 20) and Neck-Jiaji (EX-B 2) were added in acupuncture. Acupuncture was given in the time zone from 8 am through 10 am every day, once a day, 5 times a week, totally for 6 weeks. Separately, before treatment and in 2, 4 and 6 weeks of treatment, the morning blood pressure, the control rate and the symptom score were observed in the patients of the three groups. The morning blood pressure was followed up in 3 and 6 months separately. Compared with those before treatment, in 2, 4 and 6 weeks of treatment, the levels of blood pressure reduced in the patients of the three groups ( P <0.05, P <0.01). After 2-week treatment, the differences were not significant in the morning blood pressure and its control rate in the patients of the three groups (all P >0.05). In 4 and 6 weeks of treatment, the levels of the morning blood pressure in the No.2 acupuncture group were lower than those in the No.1 acupuncture group, and the results in the No.1 and No.2 acupuncture groups were all lower than those in the medication group (all P <0.05). In the follow-up visit for 3 and 6 months separately, the differences were not significant in the morning blood pressure among the three groups (all P >0.05). In 2, 4 and 6 weeks of treatment, the symptom scores reduced as compared with those before treatment in the three groups (all P <0.05). The symptom scores in the No.1 and No.2 acupuncture groups were all lower than those in the medication group (all P <0.05). The differences were not significant between the No.1 acupuncture group and the No.2 acupuncture group (all P >0.05). The comprehensive treatment of acupuncture at Fengchi (GB 20) and Neck-Jiaji (EX-B 2) combined with acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen achieve the effects of reducing the morning blood pressure in the patients with essential hypertension, relieving the symptoms of hypertension such as headache, vertigo and tinnitus and the effects are better than those of the acupuncture technique for activating blood circulation, eliminating wind and regulating the liver and spleen.

To determine whether an activity monitor (AM) could be used to detect changes in activity in dogs with osteoarthritis treated with carprofen or a placebo. Randomized controlled trial. 70 dogs with no clinically important abnormalities other than osteoarthritis for which they were not currently being treated. Dogs wore an AM continuously for 21 days. On days 8 through 21, the dogs were treated with carprofen (n = 35) or a placebo (35). Total activity counts for days 1 through 7 (baseline) were compared with total activity counts for days 15 through 21 (endpoint). The change in total activity count from baseline to endpoint was assessed within each treatment group as well as between groups. Linear regression analysis was performed to test for an association between treatment and percentage change in activity counts while controlling for other variables. For placebo-treated dogs, median baseline total activity count was not significantly different from median endpoint total activity count (1,378,408 vs 1,310,112, respectively). For dogs receiving carprofen, there was a significant increase in median activity count from baseline to endpoint (1,276,427 vs 1,374,133). When age and baseline activity counts were controlled for, dogs in the carpofen-treated group had a 20% increase in activity counts, compared with placebo-treated dogs (95% confidence interval, 10% to 26%). Results suggested that the AM used in the present study may be a valid outcome assessment tool for documenting improved activity associated with treatment in dogs with osteoarthritis.

Adherence to allergen immunotherapy improves when patients choose the route of administration: Subcutaneous or sublingual.

Sánchez, J

2015-01-01

Immunotherapy has shown to be an effective treatment for the management of some IgE-mediated allergies. However, due to its long duration, a high number of patients withdraw from it before completion. Explore if allowing patients to select the route of immunotherapy, educational sessions and strict follow-up could improve treatment compliance. Patients consulting allergy service were divided into two groups; if they chose the route of administration of immunotherapy, they were selected for the active group; if their physician decided, they were selected for the control group. All patients had to attend the allergy service monthly for control. Before the first application of immunotherapy, all patients received an educative session about the benefits and risks of the treatment. Patients in the active group received an additional session about subcutaneous and sublingual routes and they chose the most appropriate according to their personal characteristics. A total of 204 patients were in the active group and 103 were included in the control group. At six months, a total of 46 patients withdrew from immunotherapy during follow-up, 24 (11%) in the active group and 22 (21%) in the control group (p=0.02). In the active group we observed no statistically significant difference in adherence between those who preferred subcutaneous or sublingual immunotherapy; however in the control group, the drop out of sublingual immunotherapy was significantly higher than those who received subcutaneous (p=0.05). Educational sessions, strict follow-up and considering personal preferences of patients could improve adherence to allergen immunotherapy. Copyright © 2014 SEICAP. Published by Elsevier Espana.

The aim of this study was to investigate whether kinesiotaping or subacromial corticosteroid injection provides additional benefit when used with nonsteroidal anti-inflammatory drugs (NSAIDs) in patients with shoulder impingement syndrome. Patients with shoulder impingement syndrome were divided into 3 groups as follows: NSAID group (n = 33), kinesiotaping group (kinesiotaping + NSAID) (n = 33), and injection group (subacromial corticosteroid injection + NSAID) (n = 33). Outcome measures including visual analog scale, shoulder ranges of motion, Shoulder Disability Questionnaire, and University of California-Los Angeles (UCLA) scale were evaluated before and after the treatment (fourth week). A total of 99 patients (21 male and 78 female patients) were enrolled in this study. Demographic and baseline clinical characteristics of the groups (except for body mass index and visual analog scale at night, both P = 0.05) were similar between the groups (all P > 0.05). Clinical parameters were found to have improved in the 3 groups (all P < 0.001). While the kinesiotaping and injection groups showed similar improvements (all P > 0.05), each group had better outcome than did the NSAID group as regards pain (activity visual analog scale), ranges of motion, and Shoulder Disability Questionnaire and UCLA scale scores (all P < 0.05). Addition of kinesiotaping or subacromial corticosteroid injection to NSAID treatment seems to have better/similar effectiveness in patients with shoulder impingement syndrome. Therefore, kinesiotaping might serve as an alternative treatment in case (injection of) corticosteroids are contraindicated.

To compare the difference in the clinical efficacy on post-stroke upper limb spasmodic hemiplegia between the combined therapy of jingou diaoyu needling technique and Bobath technology and simple Bobath technology. Sixty patients were randomized into an observation group and a control group, 30 cases in each one. The usual medication of neurological internal medicine was used in the two groups. In the control group, Bobath facilitation technology was applied to the rehabilitation training. In the observation group, on the basis of the treatment as the control group, jingou diaoyu needling technique was used to stimulate Zhongfu (LU 1), Tianfu (LU 3), Chize (LU 5), Quchi (LI 11), Jianshi (PC 5) and Daling (PC 7). The treatment was given once a day; 5 treatments made one session and totally 4-week treatment was required in the two groups. The modified Ashworth scale, the modified Fugle-Meyer assessment (FMA) and the Barthel index (BI) were adopted to evaluate the muscular tension, the upper limb motor function and the activities of daily living (ADL) before and after treatment in the two groups. The clinical efficacy was compared between the two groups. Compared with those before treatment, the modified Ashworth scale, Fugl-Meyer score and BI score were all improved after treatment in the two groups (all P <0.01). The results in the observation group were better than those in the control group (all P <0.01). The total clinical effective rate was 93.3% (28/30) in the observation group and was 80.0% (24/30) in the control group. The efficacy in the observation group was better than that in the control group ( P <0.05). The jingou diaoyu needling technique combined with Bobath therapy achieve the superior efficacy on post-stroke upper limb spasmodic hemiplegia as compared with the simple application Bobath therapy. This combined treatment effectively relieve spasmodic state and improve the upper limb motor function and the activities of daily living.

Acute whiplash injuries are a common cause of soft tissue trauma for which the standard treatment is rest and initial immobilisation with a soft cervical collar. Because the efficacy of this treatment is unknown a randomised study in 61 patients was carried out comparing the standard treatment with an alternative regimen of early active mobilisation. Results showed that eight weeks after the accident the degree of improvement seen in the actively treated group compared with the group given standard treatment was significantly greater for both cervical movement (p less than 0.05) and intensity of pain (p less than 0.0125).

The aim of the study was to evaluate tears secretion, pH and lysozyme activity in tears aqueous layer during chemotherapy in lung, breast and bowel cancer. 36 patients were enrolled to the study. Depending on the type of cancer and type of chemotherapy patients were divided into three groups. Group I (12 patients) diagnosed with non-small-cell lung cancer treated with PE schema (cisplatin, etoposide), Group II (12 patients) with breast cancer treated with FAC schema (fluorouracil, doxorubicin, cyclophosphamide), Group III (12 patients) with bowel cancer treated with FU/LV schema (fluorouracil, leucovorin). In all the patients: Schirmer's I test, pH measurements and lysozyme test were performed. Patients were examined before chemotherapy, after 2nd, 4th, 6th cycle. In group I and II lowering of tears secretion (p < 0.001) was revealed. In group III there was higher tears secretion (p < 0.001). PH was lowered after 2nd chemotherapy course in group I and II. In further treatment pH value were in the same lower level as after the second course. In group III there was higher pH--more alkaline (p < 0.001) after 2nd cycle of treatment and it was on the same level to the end of the examination process. Lowering of lysozyme activity in the tears film in all groups (p < 0.001) was established. The higher alterations of the lysozyme activity were observed in group treated with FAC schema. Cytostatic treatment has major influence on tears aqueous layer causing alterations of tears secretions. PH alterations depending on type of chemotherapy was observed. Lowering of lysozyme activity in tears was observed. All the deteriorations aggravate with duration of chemotherapy. Alterations of tears film parameters during chemotherapy may influence upon eye surface homeostasis and infectious complication. tears aqueous layer, Schirmer's test, lysozyme activity, tears pH.

A randomized controlled trial study was performed to evaluate the efficacy of transcutaneous tibial nerve stimulation (TTNS) and sham TTNS, in patients with Parkinson disease (PD) with lower urinary tract symptoms (LUTS). Randomized controlled trial. Thirteen patients with a diagnosis of PD and bothersome LUTS were randomly allocated to one of the following groups: Group I: TTNS group (n = 8) and group II: Sham group (n = 5). Both groups attended twice a week during 5 weeks; each session lasted 30 minutes. Eight patients received TTNS treatment and 5 subjects allocated to group II were managed with sham surface electrodes that delivered no electrical stimulation. Assessments were performed before and after the treatment; they included a 3-day bladder diary, Overactive Bladder Questionnaire (OAB-V8), and the International Consultation on Incontinence Quality of Life Questionnaire Short Form (ICIQ-SF), and urodynamic evaluation. Following 5 weeks of treatment, patients allocated to TTNS demonstrated statistically significant reductions in the number of urgency episodes (P = .004) and reductions in nocturia episodes (P < .01). Participants allocated to active treatment also showed better results after treatment in the OAB-V8 and ICIQ-SF scores (P < .01, respectively). Urodynamic testing revealed that patients in the active treatment group showed improvements in intravesical volume at strong desire to void (P < .05) and volume at urgency (P < .01) when compared to subjects in the sham treatment group. These findings suggest that TTNS is effective in the treatment of LUTS in patients with PD, reducing urgency and nocturia episodes and improving urodynamic parameters as well as symptom scores measured by the OAB-V8 and health-related quality-of-life scores measured by the ICIQ-SF.

The aims of this study are to investigate the changes in spontaneous electrical activities (SEAs) and in acetylcholine (ACh), acetylcholine receptor (AChR), and acetylcholine esterase (AChE) levels after dry needling at myofascial trigger spots in model rats. Forty-eight male Sprague-Dawley rats were divided into four groups. Thirty-six rats were assigned to three model groups, which underwent MTrSs modeling intervention. Twelve rats were assigned to the blank control (BC) group. After model construction, the 36 model rats were randomly subdivided into three groups according to treatment: MTrSs model control (MC) and two dry needling groups. One dry needling group received puncturing at MTrSs (DN-M), whereas the other underwent puncturing at non-MTrSs (DN-nM). Dry needling treatment will last for two weeks, once a week. SEAs and ACh, AChR, and AChE levels were measured after one-week rest of dry needling treatment. The amplitudes and frequencies of endplate noise (EPN) and endplate spike (EPS) significantly decreased after dry needling treatment in the DN-M group. Moreover, ACh and AChR levels significantly decreased, whereas AChE significantly increased after dry needling treatment in the DN-M group. Dry needling at the exact MTrSs is more effective than dry needling at non-MTrSs.

Objective. To explore the protective effects of hydrogen-rich saline on rats with smoke inhalation injury. Methods. 36 healthy male Sprague-Dawley rats were randomly divided into 3 groups (n = 12 per group): sham group (S), inhalation injury plus normal saline treatment group (I+NS), and inhalation injury plus hydrogen-rich saline treatment group (I+HS). 30 min after injury, normal saline and hydrogen-rich saline were injected intraperitoneally (5 mL/kg) in I+NS group and I+HS group, respectively. All rats were euthanized and blood and organ specimens were collected for determination 24 h after inhalation injury. Results. Tumor necrosis factor-alpha (TNF-α) levels, malondialdehyde (MDA) concentrations, nuclear factor kappa B (NF-κB) p65 expression, and apoptosis index (AI) in I+HS group were significantly decreased (P < 0.05), while superoxide dismutase (SOD) activities were increased compared with those in I+NS group; and a marked improvement in alveolar structure was also found after hydrogen-rich saline treatment. Conclusions. Hydrogen-rich saline treatment exerts protective effects in acute lung injury induced by inhalation injury, at least in part through the activation of anti-inflammatory and antioxidant pathways and inhibition of apoptosis.

To evaluate the use and tolerability of noninvasive positive pressure ventilation (NIV) in patients with amyotrophic lateral sclerosis (ALS) early in their disease by comparing active NIV and sham NIV in patients not yet eligible for NIV use as recommended by practice guidelines. This was a single-center, prospective, double-blind, randomized, placebo (sham)-controlled pilot trial. Patients with ALS were randomized to receive either sham NIV or active NIV and underwent active surveillance approximately every 3 months until they reached a forced vital capacity (FVC) <50% or required NIV for clinical symptom management. In total, 54 participants were randomized. The mean NIV use was 2.0 hours (95% confidence interval [CI] 1.1-3.0) per day in the sham NIV treatment group and 3.3 hours (CI 2.0-4.6) per day in the active NIV group, which did not differ by treatment group (p = 0.347). The majority of sham NIV participants (88%) and active NIV participants (73%) reported only mild or no problem with NIV use. Difference of change in FVC through the treatment period by group (0.44 per month) favored active NIV (p = 0.049). Survival and changes in maximal inspiratory or expiratory pressure did not differ between treatment groups. The efficacy of early NIV in ALS should be tested in randomized, placebo-controlled trials. The trial is registered on clinicaltrials.gov (NCT00580593). This study provides Class II evidence that for patients with ALS, adherence with NIV and sham NIV are similar. © 2016 American Academy of Neurology.

Few randomized controlled trials (RCTs) of interventions for the treatment of childhood obesity have taken place outside the Western world. To test whether a good practice intervention for the treatment of childhood obesity would have a greater impact on weight status and other outcomes than a control condition in Kuala Lumpur, Malaysia. Assessor-blinded RCT of a treatment intervention in 107 obese 7- to 11-year olds. The intervention was relatively low intensity (8 hours contact over 26 weeks, group based), aiming to change child sedentary behavior, physical activity, and diet using behavior change counselling. Outcomes were measured at baseline and six months after the start of the intervention. Primary outcome was BMI z-score, other outcomes were weight change, health-related quality of life (Peds QL), objectively measured physical activity and sedentary behavior (Actigraph accelerometry over 5 days). The intervention had no significant effect on BMI z score relative to control. Weight gain was reduced significantly in the intervention group compared to the control group (+1.5 kg vs. +3.5 kg, respectively, t-test p < 0.01). Changes in health-related quality of life and objectively measured physical activity and sedentary behavior favored the intervention group. Treatment was associated with reduced rate of weight gain, and improvements in physical activity and quality of life. More substantial benefits may require longer term and more intensive interventions which aim for more substantive lifestyle changes.

There have been several reports showing 20% to 40% failure after nonoperative functional treatment for acute lateral ligament disruption of the ankle. Functional treatment after primary surgical repair has the advantage of decreasing the failure rate in comparison with functional treatment alone. Cohort study; Level of evidence, 3. A total of 132 feet of 132 patients were included in this study. Of these, 78 patients were treated with functional treatment alone (group F), and the remaining 54 patients were treated with functional treatment after primary surgical repair (group RF). The clinical results were evaluated using the Japanese Society for Surgery of the Foot Ankle-Hindfoot scale (JSSF) score, measuring the talar tilt angle and the anterior displacement of the talus in stress radiography, and noting the elapsed time between the injury and the return to the full athletic activity with no external supports. The mean JSSF scores at 2 years after injury were 95.6 ± 5.0 points in group F and 97.5 ± 2.6 points in group RF (P = .0669). The differences of the talar tilt angles compared with the contralateral side and displacement of the talus on stress radiography at 2 years after injury were 1.1° ± 1.5° and 3.6 ± 1.6 mm in group F, and 0.8° ± 0.9° and 3.2 ± 0.8 mm in group RF, respectively (P = .4093, .1883). In group F, 8 cases showed fair to poor results, with JSSF scores below 80 points and instability at 2 years after injury. In group RF, 9 cases (9.4%) showed dorsum foot pain along the superficial peroneal nerve, which disappeared within a month. The time elapsed between the injury and the patient's return to full athletic activity without any external supports was 16.0 ± 5.6 weeks in group F and 10.1 ± 1.8 weeks in group RF (P < .0001). Nonoperative functional treatment alone and functional treatment after primary surgical repair showed similar overall results after acute lateral ankle sprain, but functional treatment alone had an approximately 10% failure rate and a slower return to full athletic activity. The authors recommend that treatment be tailored to suit each individual athlete.

Iron and copper are essential microminerals that are intimately related. The present study was performed to determine the effect of iron-deficiency anemia (IDA) and treatment with iron on laboratory indicators of copper status. Hemoglobin, mean corpuscular volume erythrocyte Zn protoporphyrin, serum ferritin, serum copper, serum ceruloplasmin, and erythrocyte CuZn-superoxide dismutase (SOD) activity were studied in 12 adult women with IDA before and after iron treatment for 60-90 d (100 mg/d Fe, as ferric polymaltose) and in 27 women with normal iron status. Prior to treatment with iron, serum copper and ceruloplasmin were not different between the groups and treatment with iron did not affect these measures. IDA women, before and after treatment with iron, presented a 2.9- and 2-fold decrease in erythrocyte CuZn-SOD activity compared to women with normal iron status (p < 0.001). Treatment with iron increased erythrocyte CuZn-SOD activity of the IDA group; however, this change was not statistically significant. In conclusion, CuZn-SOD activity is decreased in IDA. Measurement of this enzyme activity is not useful for evaluating copper nutrition in iron-deficient subjects.

Individuals recovering from addictions frequently cite spirituality as a helpful influence. However, little is known about whether or how spirituality could be incorporated into formal treatment in a manner that is sensitive to individual differences. In the present study, focus groups were conducted with 25 methadone-maintained outpatients (primarily high-school educated, African-American males) to examine beliefs about the role of spirituality in recovery and its appropriateness in formal treatment. Groups also discussed the relationship between spirituality and behavior during active addiction. Thematic analyses suggested that spirituality and religious practices suffered in complex ways during active addiction, but went “hand in hand” with recovery. Nearly all participants agreed that integration of a voluntary spiritual discussion group into formal treatment would be preferable to currently available alternatives. One limitation was that all participants identified as strongly spiritual. Studies of more diverse samples will help guide the development and evaluation of spiritually based interventions in formal treatment settings. PMID:20025443

Diagnosis and management strategies for shin splints in active duty military populations closely resemble those in civilian athletic populations. There is a paucity of evidence supporting the use of many of these interventions. The purpose of this study was to present data on the Shin Saver orthosis as a treatment for shin splints in an active duty military population and to review current condition management. Twenty-five subjects diagnosed with shin splints by a U.S. Army physical therapist were randomly assigned to a shin orthosis treatment group or a control group. There was no significant difference between treatment and control groups in days to finish a 0.5-mile run pain free. Visual analog scales for pain at intake versus after 1 week of relative rest revealed no significant improvement in symptoms in either group. Current best-practice guidelines support a treatment program of rest, cryotherapy, and a graduated walk-to-run program.

To investigate whether an exercise program, initially focusing on knee stabilization and subsequently on muscle strength and performance of daily activities is more effective than an exercise program focusing on muscle strength and performance of daily activities only, in reducing activity limitations in patients with knee osteoarthritis (OA) and instability of the knee joint. A single-blind, randomized, controlled trial involving 159 knee OA patients with self-reported and/or biomechanically assessed knee instability, randomly assigned to two treatment groups. Both groups received a supervised exercise program for 12 weeks, consisting of muscle strengthening exercises and training of daily activities, but only in the experimental group specific knee joint stabilization training was provided. Outcome measures included activity limitations (Western Ontario and McMaster Universities Osteoarthritis Index - WOMAC physical function, primary outcome), pain, global perceived effect and knee stability. Both treatment groups demonstrated large (∼20-40%) and clinically relevant reductions in activity limitations, pain and knee instability, which were sustained 6 months post-treatment. No differences in effectiveness between experimental and control treatment were found on WOMAC physical function (B (95% confidence interval - CI) = -0.01 (-2.58 to 2.57)) or secondary outcome measures, except for a higher global perceived effect in the experimental group (P = 0.04). Both exercise programs were highly effective in reducing activity limitations and pain and restoring knee stability in knee OA patients with instability of the knee. In knee OA patients suffering from knee instability, specific knee joint stabilization training, in addition to muscle strengthening and functional exercises, does not seem to have any additional value.

Comparison Between Individually and Group-Based Insulin Pump Initiation by Time-Driven Activity-Based Costing

PubMed Central

Ridderstråle, Martin

2017-01-01

Background: Depending on available resources, competencies, and pedagogic preference, initiation of insulin pump therapy can be performed on either an individual or a group basis. Here we compared the two models with respect to resources used. Methods: Time-driven activity-based costing (TDABC) was used to compare initiating insulin pump treatment in groups (GT) to individual treatment (IT). Activities and cost drivers were identified, timed, or estimated at location. Medical quality and patient satisfaction were assumed to be noninferior and were not measured. Results: GT was about 30% less time-consuming and 17% less cost driving per patient and activity compared to IT. As a batch driver (16 patients in one group) GT produced an upward jigsaw-shaped accumulative cost curve compared to the incremental increase incurred by IT. Taking the alternate cost for those not attending into account, and realizing the cost of opportunity gained, suggested that GT was cost neutral already when 5 of 16 patients attended, and that a second group could be initiated at no additional cost as the attendance rate reached 15:1. Conclusions: We found TDABC to be effective in comparing treatment alternatives, improving cost control and decision making. Everything else being equal, if the setup is available, our data suggest that initiating insulin pump treatment in groups is far more cost effective than on an individual basis and that TDABC may be used to find the balance point.

This study explored the automatic and controlled processes that may influence performance on an implicit measure across cognitive-behavioral group therapy for panic disorder. The Quadruple Process model was applied to error scores from an Implicit Association Test evaluating associations between the concepts Me (vs. Not Me) + Calm (vs. Panicked) to evaluate four distinct processes: Association Activation, Detection, Guessing, and Overcoming Bias. Parameter estimates were calculated in the panic group (n = 28) across each treatment session where the IAT was administered, and at matched times when the IAT was completed in the healthy control group (n = 31). Association Activation for Me + Calm became stronger over treatment for participants in the panic group, demonstrating that it is possible to change automatically activated associations in memory (vs. simply overriding those associations) in a clinical sample via therapy. As well, the Guessing bias toward the calm category increased over treatment for participants in the panic group. This research evaluates key tenets about the role of automatic processing in cognitive models of anxiety, and emphasizes the viability of changing the actual activation of automatic associations in the context of treatment, versus only changing a person's ability to use reflective processing to overcome biased automatic processing.

Static electric field therapy by high voltage alternating current (EF-HVAC) is a traditional complementary Japanese medicine used for headache, shoulder stiffness, chronic constipation and insomnia. Open-label studies and clinical experience in Japan have suggested that this electric field therapy is safe and effective in treating chronic arthritis. We evaluated the efficacy of EF-HVAC therapy in a randomized, double-blinded, sham-controlled trial in patients with active rheumatoid arthritis (RA) in community-based general physician centers. Thirty patients fulfilling American College of Rheumatology (ACR) criteria for RA were treated with EF-HVAC therapy with the LEGACIS PLUS System (COCOROCA Corp., Tokyo, Japan) or sham therapy for 12 weeks and followed for 4 weeks without treatment. The disease activity score 28 (DAS28-CRP), visual analogue scale for pain (VAS), modified health assessment questionnaire (MHAQ), and inflammatory parameters were used as the outcome variable. Twenty four patients (n = 12 in each group) were analyzed by a per protocol analysis. Although a significant reduction in DAS28-CRP was observed in EF-HVAC group at 8 and 12 weeks compared to before treatment, there were no significant differences in DAS28-CRP scores during treatment between two groups. The scale of VAS was also significantly decreased by the treatment with EF-HVAC compared to before treatment, in addition, the scale of VAS in EF-HVAC group was significantly lower than sham group at 8 and 12 weeks. Changes in another parameters including MHAQ were not significant between before and after treatment, or by all comparative study between two groups. There were no adverse events related the treatment. In conclusion, the EF-HVAC therapy has a beneficial effect on the improvement to subjective pain of RA. PMID:23874073

It is normally recognized that the preferred treatment in large toxic thyroid nodules should be thyroidectomy. The aim of the study was to assess the efficacy of combined laser ablation treatment (LAT) and radioiodine 131 (131I) treatment of large thyroid toxic nodules with respect to rapidity of control of local symptoms, of hyperthyroidism, and of reduction of administered 131I activity in patients at refusal or with contraindications to surgery. We conducted a pilot study at a single center specializing in thyroid care. Fifteen patients were treated with LAT, followed by 131I (group A), and a series of matched consecutive patients were treated by 131I only (group B). Laser energy was delivered with an output power of 3 W (1800 J per fiber per treatment) through two 75-mm, 21-gauge spinal needles. Radioiodine activity was calculated to deliver 200 Gy to the hyperfunctioning nodule. Thyroid function, thyroid peroxidase antibody, thyroglobulin antibody, ultrasound, and local symptoms were measured at baseline and up to 24 months. Nodule volume reduction at 24 months was: 71.3 ± 13.4 vs 47.4 ± 5.5%, group A (LAT+131I) vs group B (131I), respectively; P < .001). In group A (LAT+131I), a reduction in radioiodine-administered activity was obtained (-21.1 ± 8.1%). Local symptom score demonstrated a more rapid reduction in group A (LAT+131I). In three cases, no 131I treatment was needed after LAT. In this pilot study, combined LAT/131I treatment induced faster and greater improvement of local and systemic symptoms compared to 131I only. This approach seems a possible alternative to thyroidectomy in patients at refusal of surgery.

This study describes and evaluates a cognitive-behavioral treatment group for people with chronic physical illness in Hong Kong. We developed a group protocol based on the understanding that Chinese people generally prefer a structured group format, expect group leaders to be active and directive, and are not used to expressing opinions and emotions in groups. The experimental and waitlist control groups had 38 and 35 participants, respectively. A standardized questionnaire was administered to all participants before and after the group treatment. Results suggest that members of the experimental group showed improvements in mental health, negative automatic thoughts, and negative emotions when compared to those in the waitlist control groups, and at the end of group treatment. Implications for designing and running a culturally attuned CBT group for Chinese people are discussed.

Temporomandibular disorder (TDM) is the most common source of orofacial pain of a non-dental origin. Sleep bruxism is characterized by clenching and/or grinding the teeth during sleep and is involved in the perpetuation of TMD. The aim of the present study was to investigate the effects of massage therapy, conventional occlusal splint therapy and silicone occlusal splint therapy on electromyographic activity in the masseter and anterior temporal muscles and the intensity of signs and symptoms in individuals with severe TMD and sleep bruxism. Sixty individuals with severe TMD and sleep bruxism were randomly distributed into four treatment groups: 1) massage group, 2) conventional occlusal splint group, 3) massage + conventional occlusal splint group and 4) silicone occlusal splint group. Block randomization was employed and sealed opaque envelopes were used to conceal the allocation. Groups 2, 3 and 4 wore an occlusal splint for four weeks. Groups 1 and 3 received three weekly massage sessions for four weeks. All groups were evaluated before and after treatment through electromyographic analysis of the masseter and anterior temporal muscles and the Fonseca Patient History Index. The Wilcoxon test was used to compare the effects of the different treatments and repeated-measures ANOVA was used to determine the intensity of TMD. The inter-group analysis of variance revealed no statistically significant differences in median frequency among the groups prior to treatment. In the intra-group analysis, no statistically significant differences were found between pre-treatment and post-treatment evaluations in any of the groups. Group 3 demonstrated a greater improvement in the intensity of TMD in comparison to the other groups. Massage therapy and the use of an occlusal splint had no significant influence on electromyographic activity of the masseter or anterior temporal muscles. However, the combination of therapies led to a reduction in the intensity of signs and symptoms among individuals with severe TMD and sleep bruxism. This study is registered in August, 2014 in the ClinicalTrials.gov (NCT01874041).

Prednisone treatment alters the serum amylase and lipase activities in normal dogs without causing pancreatitis.

In order to test the hypothesis that treatment with glucocorticoids causes pancreatitis in dogs, 18 mongrel dogs were divided into three groups of six individuals, each group receiving prednisone at different doses orally or intramuscularly for two weeks. Two groups consisting of six dogs each served as controls. Treatment for two weeks with oral prednisone at 1.2 mg/kg body weight or at 4 mg/kg body weight daily decreased the serum amylase activities, but increased the serum lipase activities. Postmortem examinations revealed microscopic evidence of mild pancreatitis in only one dog given prednisone, that clinically appeared normal. It was concluded that daily doses of 4 mg prednisone/kg body weight or less given orally or intramuscularly for two weeks do not cause pancreatitis in dogs. PMID:6202383

This article analyzes differences in displacement of ANS and of the upper first molar when different vectors of force are delivered to the maxilla in non-full-banded Phase I mixed-dentition treatment of Class II malocclusion. The sample is identical to that for which we have previously reported differences in change in several key measures of mandibular and facial shape. It includes a cervical-traction group, a high-pull-to-upper-molar group, a modified-activator group, and an untreated Class II control group. Using newly developed computer-conducted procedures, which are described, we have been able to partition the orthodontic and orthopedic components of upper molar displacement and also to isolate treatment effects from those attributable to spontaneous growth and development. In the region of ANS, small but statistically significant and clinically meaningful differences were noted between treatments. When the intercurrent effects of growth and development had been factored out (Table III), orthopedic distal displacement of ANS was significantly greater in the high-pull and cervical groups than in the activator group. Orthopedic downward displacement of ANS was seen to be significantly greater in the cervical group than in the high-pull and activator groups. In the region of the first molar cusp, mean distal displacement of the tooth as an orthopedic effect was found to be almost identical in the cervical and high-pull groups (although variability was greater in the cervical group), but the mean orthodontic effect was significantly greater in the high-pull group than in the cervical group. In the cervical group, where relatively light forces were used for relatively long treatment periods on average, more of the total distal displacement of the upper molar was of an orthopedic character than of an orthodontic character. Conversely, in the high-pull group, in which relatively heavier forces tended to be used for briefer treatment periods, most of the distal displacement at the upper molar was of an orthodontic character. These observations are contrary to expectations from conventional orthodontic theory. In the activator-treated group, roughly equal components of the treatment-associated distal displacement of the upper molar were of the orthodontic and orthopedic types. As concerns changes in the vertical direction in the region of the molar cusp, significant intrusion of both the orthopedic and orthodontic types was seen in the high-pull sample as compared to each of the other groups examined.(ABSTRACT TRUNCATED AT 400 WORDS)

The prevention and treatment of childhood obesity is a key public health challenge. However, certain groups within populations have markedly different risk profiles for obesity and related health behaviours. Well-designed subgroup analysis can identify potential differential effects of obesity interventions, which may be important for reducing health inequalities. The study aim was to evaluate the consistency of the effects of active video games across important subgroups in a randomised controlled trial (RCT). A two-arm, parallel RCT was conducted in overweight or obese children (n=322; aged 10-14 years) to determine the effect of active video games on body composition. Statistically significant overall treatment effects favouring the intervention group were found for body mass index, body mass index z-score and percentage body fat at 24 weeks. For these outcomes, pre-specified subgroup analyses were conducted among important baseline demographic (ethnicity, sex) and prognostic (cardiovascular fitness) groups. No statistically significant interaction effects were found between the treatment and subgroup terms in the main regression model (p=0.36 to 0.93), indicating a consistent treatment effect across these groups. Preliminary evidence suggests an active video games intervention had a consistent positive effect on body composition among important subgroups. This may support the use of these games as a pragmatic public health intervention to displace sedentary behaviour with physical activity in young people.

Some have recommended surgical treatment of Grade-III lateral ligament injuries in very active individuals with high functional demands on the ankle. The purpose of this study was to establish whether surgery provides better long-term results than functional treatment for acute ruptures of the lateral ligaments of the ankle. Physically active Finnish men (mean age, 20.4 years) with an acute Grade-III lateral ligament rupture of the ankle were randomly allocated to surgical (n = 25) or functional (n = 26) treatment. Ligament injury was confirmed with stress radiographs. Surgical treatment comprised suture repair of the injured ligament(s) within the first week after injury. A below-the-knee plaster cast was worn for six weeks with full weight-bearing. Functional treatment consisted of the use of an Aircast ankle brace for three weeks. The main outcome measures included final follow-up examinations, calculation of an ankle score, stress radiographs, and magnetic resonance imaging scans. Fifteen (60%) of twenty-five surgically treated patients and eighteen (69%) of twenty-six functionally treated patients returned for long-term follow-up (mean duration, fourteen years). All patients in both groups had recovered their preinjury activity level and reported that they could walk and run normally. The prevalence of reinjury was one of fifteen in the surgical group and seven of eighteen in the functional treatment group (risk difference: 32%; 95% confidence interval: 6% to 58%). The mean ankle score did not differ significantly between the groups (mean difference: 8.3 points; 95% confidence interval: -0.03 to 16.6 points). Stress radiographs revealed no difference between groups with regard to the mean anterior drawer (-1 mm in the surgical group and 0 mm in the functional treatment group; mean difference: 0.7 mm; 95% confidence interval: -1.4 to 2.7 mm) or mean tilt angle (0° in both groups; mean difference: 0.1°; 95% confidence interval: -3.2° to 3.5°). Grade-II osteoarthritis was observed on magnetic resonance images of four of the fifteen surgically treated patients and in none of the eighteen functionally treated patients (risk difference: 27%; 95% confidence interval: 4% to 49%). These findings indicate that, in terms of recovery of the preinjury activity level, the long-term results of surgical treatment of acute lateral ligament rupture of the ankle correspond with those of functional treatment. Although surgery appeared to decrease the prevalence of reinjury of the lateral ligaments, there may be an increased risk for the subsequent development of osteoarthritis.

Individuals with developmental disabilities may engage in automatically reinforced behaviors that may interfere with learning opportunities. Manipulation of motivating operations has been shown to reduce automatically maintained behavior in some individuals. Considering behavioral indicators of satiation may assist in identifying the point at which an abolishing operation has begun to effect behavior. The purpose of this study was to evaluate the effects of pre-session satiation of automatic reinforcement on subsequent levels of stereotypy and activity engagement during group activities for three males ages 5 to 13 years with developmental disabilities. Following functional analyses with analogue conditions, an alternating treatment design compared a pre-session access to stereotypy condition with a no-pre-session access condition prior to group activity sessions. Results indicated that pre-session satiation of the putative reinforcer produced by stereotypy was effective in decreasing stereotypy and increasing activity engagement during subsequent group activities for all participants. These findings add to the literature supporting the effectiveness of abolishing operations to decrease automatically maintained stereotypy. © The Author(s) 2013.

To investigate the effects of postnatal dexamethasone treatment on aerobic fitness and physical activity levels in school-aged children born with very low birth weight (VLBW). This was a follow-up study of 65 VLBW infants who participated in a randomized controlled trial of dexamethasone (DEX) to reduce ventilator dependency. Aerobic fitness was determined from peak oxygen uptake (VO(2peak)) with a cycle ergometer. Habitual physical activity was assessed by questionnaire. A trend for a treatment with an interaction between treatment and of diagnosis of chronic lung disease (CLD) was found, with the children in the placebo group with CLD having the lowest VO(2peak) (P = .09). Reduced fitness was seen in 53% of the group treated with DEX and 48% of the group given placebo. No between-group differences in physical activity were seen. Parental reports suggested that nearly two-thirds of the children participated in < 1 hour per week of vigorous physical activity, which was explained in part by decreased large airway function (r = 0.30; P = .03). We found no adverse effect of postnatal DEX on aerobic fitness or habitual physical activity at school age. However, the reduced fitness and physical activity levels emphasize the need for closer follow-up and early interventions promoting physical activity to reduce the risk of chronic disease in this at-risk population.

To investigate whether vitamin E protects against hepatic fibrosis in mice with Schistosoma japonicum infection, 24 pathogen-free Kunming mice were selected and randomly divided into four groups: control (uninfected, untreated), model (infected, untreated), low-dose intervention (infected, vitamin E-treated, 30 mg/g bodyweight/day) and high-dose intervention (infected, vitamin E-treated, 60 mg/g bodyweight/day). Mice were infected with Schistosoma japonicum by inoculating abdominal skin with snail hosts. The activities of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were detected in hepatic tissue by colorimetry. The expression levels of laminin (LN), hyaluronic acid (HA), procollagen type Ⅲ (PC-III) and type Ⅳ collagen (IV-C) were detected in the serum by radioimmunoassay. Finally, areas and numbers of granulomas were assessed through histopathology 42 days following treatment. The results revealed that mean areas of granulomas were smaller in the low- and high-dose intervention groups compared to those in the model group. Furthermore, the higher dose of vitamin E resulted in smaller granulomas than the low dose. The levels of LN, HA, PC-III and IV-C in the serum were lower following vitamin E treatment than in the model group. By contrast, activity of SOD, GPx and CAT in hepatic tissue was higher following vitamin E treatment compared to the model group. The activity of MDA was lower in hepatic tissue following vitamin E treatment compared to the model group, but was higher compared to controls. In general, the higher dose of vitamin E affected measurements to a greater extent than the lower dose. In conclusion, vitamin E treatment may reduce the growth of granulomas, slowing the process of hepatic fibrosis, and this effect may be the result of the altered activity of the oxidation-reduction enzyme system.

OBJECTIVE: To compare the impact of mass treatment with oral azithromycin and topical tetracycline on the prevalence of active trachoma. METHODS: A total of 1803 inhabitants from 106 households of eight Gambian villages were randomized, in pairs, to receive either three doses of azithromycin at weekly intervals, or daily topical tetracycline over 6 weeks. Ocular examinations were conducted before treatment, and 2, 6 and 12 months after treatment. FINDINGS: Prior to treatment, 16% of the study participants had active trachoma. Two months after treatment, the prevalence of trachoma was 4.6% and 5.1% in the azithromycin and the tetracycline groups, respectively (adjusted odds ratio (OR) = 1.09; 95% confidence interval (CI) = 0.53, 2.02). Subsequently, the prevalence rose to 16% in the tetracycline group, while remaining at 7.7% in the azithromycin group (adjusted OR at 12 months = 0.52; 95% CI = 0.34, 0.80). At 12 months post-treatment, there were fewer new prevalent cases in the azithromycin group, and trachoma resolution was significantly better for this group (adjusted OR = 2.02; 95% CI = 1.42, 3.50). CONCLUSION: Oral azithromycin therefore appears to offer a means for controlling blinding trachoma. It is easy to administer and higher coverages may be possible than have been achieved hitherto.

2012-05-01

As one of the problematic behaviors in patients with major depressive disorder (MDD), excessive online game play (EOP) has been reported in a number of recent studies. Bupropion has been evaluated as a potential treatment for MDD and substance dependence. We hypothesized that bupropion treatment would reduce the severity of EOP as well as depressive symptoms. Fifty male subjects with comorbid EOP and MDD were randomly assigned to bupropion + education for internet use (EDU) or placebo + EDU groups. The current study consisted in a 12-week, prospective, randomized, double-blind clinical trial, including an eight-week active treatment phase and a four-week post treatment follow-up period. During the active treatment period, Young Internet Addiction Scale (YIAS) scores and the mean time of online game playing in the bupropion group were greatly reduced compared with those of the placebo group. The Beck Depression Inventory (BDI) scores in the bupropion group were also greatly reduced compared with those of the placebo group. During the four-week post-treatment follow-up period, bupropion-associated reductions in online game play persisted, while depressive symptoms recurred. Conclusively, bupropion may improve depressive mood as well as reduce the severity of EOP in patients with comorbid MDD and online game addiction.

The current study consisted in a 12-week, prospective, randomized, double-blind clinical trial, including an eight-week active treatment phase and a four-week post treatment follow-up period. During the active treatment period, Young Internet Addiction Scale (YIAS) scores and the mean time of online game playing in the bupropion group were greatly reduced compared with those of the placebo group. The Beck Depression Inventory (BDI) scores in the bupropion group were also greatly reduced compared with those of the placebo group. During the four-week post-treatment follow-up period, bupropion-associated reductions in online game play persisted, while depressive symptoms recurred. Conclusively, bupropion may improve depressive mood as well as reduce the severity of EOP in patients with comorbid MDD and online game addiction. PMID:21447539

This study evaluated the activity of cardiac and renal antioxidant enzymes [superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX), and glutathione reductase (GR)] and whether chronic treatment with tempol, a cell membrane-permeable SOD mimetic, ameliorates the hypertension of hyperthyroidism. Two experiments were performed. In experiment I, the following four groups of male Wistar rats were used: control group and three groups that received thyroxine (T4) at 10, 50, or 75 microg x rat(-1) x day(-1). In experiment II, tempol was orally administered (18 mg x kg(-1) x day(-1)) to control and T4-treated (75 microg x rat(-1) x day(-1)) rats. All treatments were maintained for 6 wk. Body weight, tail systolic blood pressure (BP), and heart rate were measured one time a week, and direct BP and morphological, metabolic, plasma, and renal variables were measured at the end of the experiment. Enzymatic activities were measured in renal cortex and medulla and right and left ventricles. In renal cortex, SOD activity was decreased in the T4-75 group, and there was a dose-related increase in CAT activity and decrease in GPX and GR activities in T4-treated groups. Activity of all antioxidant enzymes was reduced in left ventricle in T4-50 and T4-75 groups and in right ventricle in the T4-75 group. Tempol reduced BP, plasma malondialdehyde, and total urinary excretion of F2 isoprostanes in hypertensive hyperthyroid rats but not in controls. Tempol did not improve cardiac hypertrophy, proteinuria, or creatinine clearance in hyperthyroid rats. In conclusion, the results obtained indicate that the activity of SOD, GPX, and GR in renal and cardiac tissues is decreased in hyperthyroidism and that antioxidant treatment with tempol ameliorates T4-induced hypertension.

The purpose of this study was to explore the effects of Xueshuan Xinmai tablets (XXMT) for the treatment of cognition, brain activation in the rehabilitation period of ischemic stroke patients. 28 adults patients, aged 50-80 years, in the rehabilitation period of ischemic stroke were divided into XXMT treatment group and placebo control group. Patients received 3 months treatment (oral 0.8 g, 3 times per day). Before and after treatment, all patients were evaluated by a series of neuropsychological tests followed by resting-state functional magnetic resonance imaging (fMRI). In the XXMT treatment group, the patients' episodic memory showed significant improvement. The resting-state fMRI analysis indicated that a significant decline in the fractional amplitude of low-frequency fluctuation value was observed in the bilateral middle cingulate gyrus. Yiqi Huoxue effect under XXMT administration has a favorable mediation on episodic memory, consequently suppresses the activation of the cingulate gyrus in the rehabilitation period of ischemic stroke patients.

The incidence of insomnia and depression in the elder population is significant. It is hoped that use of light treatment for this group could provide safe, economic, and effective rapid recovery. In this home-based trial we treated depressed elderly subjects with bright white (8,500 Lux) and dim red (<10 Lux) light for one hour a day at three different times (morning, mid-wake and evening). A placebo response washout was used for the first week. Wake treatment was conducted prior to the initiation of treatment, to explore antidepressant response and the interaction with light treatment. Urine and saliva samples were collected during a 24-hour period both before and after treatment and assayed for aMT6s and melatonin respectively to observe any change in circadian timing. Subjects wore a wrist monitor to record light exposure and wrist activity. Daily log sheets and weekly mood (GDS) and physical symptom (SAFTEE) scales were administered. Each subject was given a SCID interview and each completed a mood questionnaire (SIGH-SAD-SR) before and after treatment. Also, Hamilton Depression Rating (SIGH-SAD version) interviews were conducted by a researcher who was blind to the treatment condition. A control group of healthy, age-matched, volunteers was studied for one day to obtain baseline data for comparison of actigraphy and hormone levels. Eighty-one volunteers, between 60 and 79 years old, completed the study. Both treatment and placebo groups experienced mood improvement. Average GDS scores improved 5 points, the Hamilton Depression Rating Scale (HDRS) 17 scores (extracted from the self-rated SIGH-SAD-SR) improved 6 points. There were no significant treatment effects or time-by-treatment interactions. No significant adverse reactions were observed in either treatment group. The assays of urine and saliva showed no significant differences between the treatment and placebo groups. The healthy control group was active earlier and slept earlier but received less light than the depressed group at baseline. Antidepressant response to bright light treatment in this age group was not statistically superior to placebo. Both treatment and placebo groups experienced a clinically significant overall improvement of 16%.

Objective To determine whether an activity monitor (AM) could be used to detect changes in activity in dogs with osteoarthritis treated with carprofen or a placebo. Design Randomized controlled trial. Animals 70 dogs with no clinically important abnormalities other than osteoarthritis for which they were not currently being treated. Procedures Dogs wore an AM continuously for 21 days. On days 8 through 21, the dogs were treated with carprofen (n = 35) or a placebo (35). Total activity counts for days 1 through 7 (baseline) were compared with total activity counts for days 15 through 21 (endpoint). The change in total activity count from baseline to endpoint was assessed within each treatment group as well as between groups. Linear regression analysis was performed to test for an association between treatment and percentage change in activity counts while controlling for other variables. Results For placebo-treated dogs, median baseline total activity count was not significantly different from median endpoint total activity count (1,378,408 vs 1,310,112, respectively). For dogs receiving carprofen, there was a significant increase in median activity count from baseline to endpoint (1,276,427 vs 1,374,133). When age and baseline activity counts were controlled for, dogs in the carpofen-treated group had a 20% increase in activity counts, compared with placebo-treated dogs (95% confidence interval, 10% to 26%). Conclusions and Clinical Relevance Results suggested that the AM used in the present study may be a valid outcome assessment tool for documenting improved activity associated with treatment in dogs with osteoarthritis.

The influence of surface chemistry and solution pH on the adsorption of benzene and toluene on activated carbon and its acid and heat treated forms were studied. A commercial coal-based activated carbon F-400 was chosen as carbon parent. The carbon samples were obtained by modification of F-400 by means of chemical treatment with HNO3 and thermal treatment under nitrogen flow. The treatment with nitric acid caused the introduction of a significant number of oxygenated acidic surface groups onto the carbon surface, while the heat treatment increases the basicity of carbon. The pore characteristics were not significantly changed after these modifications. The dispersive interactions are the most important factor in this adsorption process. Activated carbon with low oxygenated acidic surface groups (F-400Tox) has the best adsorption capacity.

To explore the effects of Jingui Shenqi Pill (JSP) on the testis telomerase activity in mice of Shen-yang deficiency syndrome (SYDS). The SYDS model was prepared in 30 mice by over-fatigue and sexual overstrain. They were randomly divided into the model group and the JSP group, 15 in each group. Another 15 normal male mice were selected as the normal group. Mice in the normal group were fed routinely, with distilled water administered intragastrically at the daily dose of 0.1 mL/10 g. Mice in the model group were also administered intragastrically with distilled water at the daily dose of 0.1 mL/10 g while modeling establishment. Mice in the treatment group were administered intragastrically with JSP suspension at 0.1 mL/10 g (the concentration was 0.241 g/mL). The intervention lasted for 4 weeks. Four weeks later, the testis telomerase activity was detected in the three groups by ELISA. The SYDS model was replicated successfully by over-fatigue and sexual overstrain. JSP could improve the signs of mice of SYDS. Compared with the normal group, the activity of testis telomerase decreased in the model group (P < 0.01). Compared with the model group, the testis telomerase activity markedly increased in the treatment group (P < 0.01). The testis telomerase activity in mice of SYDS caused by over-fatigue and sexual overstrain obviously decreased, when compared with that in mice of the normal group. JSP could recover its activity.

To study whether Abacor, a product based on isolated soy protein with high and standardised levels of isoflavones and cotyledon soy fibres, was more effective in lowering total and LDL cholesterol than placebo. Randomised, placebo-controlled, double-blind, parallel group, single centre study. Primary care in Joensuu, North Karelia, Finland. Subjects were screened from the patient database of the health centre; 30 were randomised to the Abacor group and 30 subjects to placebo. Eight subjects were withdrawn, six from the active group, two from the placebo group. The preparations were given as two daily liquid supplements in addition to the subjects' regular diets for 6 weeks. Abacor showed a statistically significant lipid-lowering effect as compared to placebo, although an unexpected reduction was seen in the placebo group. The estimated difference between active treatment and placebo was 0.25 mmol/l (95% CI 0.01, 0.50; P=0.049) for total cholesterol, corresponding to reductions of 8.3 and 5.1%, respectively. The difference in reduction of LDL-cholesterol was 0.27 mmol/l (95% CI 0.06, 0.49; P=0.014) and corresponded to a reduction of 13.2% in the active treatment group, and 8.0% in the placebo group. Abacor showed a rapid onset of effect, as compared with placebo. During a wash-out period of 4 weeks after treatment, the subjects returned to pre-treatment cholesterol levels. Added to a regular diet, Abacor significantly reduced LDL-cholesterol and total cholesterol. These beneficial effects occurred within 6 weeks of treatment.

Introduction: One of the main features of orthodontic treatment is the cooperation of the doctor with the patient. Active growth of a child's organism at the age from 6 to 12 has not only physiological but also psychological aspects of development. Motivation for orthodontic treatment is absent during mixed dentition. Only taking into account the somato-psychological status and the psycho-emotional condition of the patient during the orthodontic treatment allows to choose an optimal treatment option and to predict its effectiveness. The aim: The aim of our study was to increase the motivation for orthodontic treatment for children during the period of mixed dentition by using informative and accessible psychological methods to raise awareness and the role of parents. Materials and methods: 30 patients at the age from 6 to 12 received orthodontic treatment. The treatment contains targeted psychological training, aimed at activating, strengthening and reinforcing the motivation for treatment for children and their parents. Results: The proposed method gives a significant reduction in the percentage of treatment interruption - according to the literature up to 35.7%, in our study - up to 13.4%. The active treatment period decreased by 1.6 times, and the patient's lack of discipline - by 4 times compared with the control group. There were 2.5 times less undisciplined patients in the experimental group than in the control group. Conclusions: The obtained results testify to the necessity of using psychological methods to increase the motivation for orthodontic treatment for children during the period of mixed dentition.

To investigate the efficacy and safety of technetium-99 conjugated with methylene diphosphonate ( 99 Tc-MDP, Yunke Pharmaceutical industry) in the treatment of rheumatoid arthritis (RA). A total of 120 patients with active RA were randomly divided into three groups: Group A (receiving oral meloxicam tablets); Group B (receiving intravenous drip of 99 TC-MDP); Group C (receiving combination treatment of intravenous drip of 99 Tc-MDP and oral meloxicam tablets). The main clinical and laboratory parameters were evaluated at baseline and after 14 days of therapy. After 14 days of treatment, American College of Rheumatology 20 response was 15.62%, 34.04% and 48.78% in the three groups, respectively. The incidence of adverse events in three groups were 3.13%, 8.51% and 9.76% respectly, and has no significant difference. In addition, biochemical markers of bone metabolism including bone alkaline phosphatase (BAP), tartrate resistant acid phosphatase (TRAP) and dickkopf-1 (DKK-1), all improved in the three groups, although more significant in Group B than Group A, and more significant in the combination group than monotherapy groups. 99 Tc-MDP has good efficacy and safety in the treatment of active RA patients; the benefit was more remarkable when 99 Tc-MDP was combined with NSAIDs. 99 Tc-MDP may also have potential to improve bone metabolism. © 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

Flavanol-rich chocolate and lycopene-rich tomato extract have attracted interest as potential alternative treatment options for hypertension, a known risk factor for cardiovascular morbidity and mortality. Treatment of prehypertension (SBP 120-139/DBP 80-89 mmHg) may forestall progression to hypertension. However, there has been only limited research into non-pharmacological treatment options for prehypertension. We investigated the effect of dark chocolate or tomato extract on blood pressure, and their acceptability as an ongoing treatment option in a prehypertensive population. Our trial consisted of two phases: a randomised controlled three-group-parallel trial over 12 weeks (phase 1) followed by a crossover of the two active treatment arms over an additional 12-week period (phase 2). Group 1 received a 50 g daily dose of dark chocolate with 70% cocoa containing 750 mg polyphenols, group 2 were allocated one tomato extract capsule containing 15 mg lycopene per day, and group 3 received one placebo capsule daily over 8 weeks followed by a 4-week washout period. In phase 2 the active treatment groups were crossed over to receive the alternative treatment. Median blood pressure, weight, and abdominal circumference were measured 4-weekly, and other characteristics including physical activity, general health, energy, mood, and acceptability of treatment were assessed by questionnaire at 0, 8 and 20 weeks. We analysed changes over time using a linear mixed model, and one time point differences using Kruskal-Wallis, Fisher's-Exact, or t-tests. Thirty-six prehypertensive healthy adult volunteers completed the 6-month trial. Blood pressure changes over time within groups and between groups were not significant and independent of treatment. Weight and other characteristics did not change significantly during the trial. However, a marked difference in acceptability between the two treatment forms (chocolate or capsule) was revealed (p < 0.0001). Half of the participants allocated to the chocolate treatment found it hard to eat 50 g of dark chocolate every day and 20% considered it an unacceptable long-term treatment option, whereas all participants found it easy and acceptable to take a capsule each day for blood pressure. Our study did not find a blood pressure lowering effect of dark chocolate or tomato extract in a prehypertensive population. Practicability of chocolate as a long-term treatment option may be limited. http://www.anzctr.org.au Identifier: ACTRN12609000047291.

To evaluate the efficacy on hemiplegic spasticity after cerebral infarction treated with plum blossom needle tapping therapy at the key points and Bobath therapy. Eighty patients were collected, in compliance with the inclusive criteria of hemiplegic spasticity after cerebral infarction, and randomized into an observation group and a control group, 40 cases in each one. In the control group, Bobath manipulation therapy was adopted to relieve spasticity and the treatment of 8 weeks was required. In the observation group, on the basis of the treatment as the control group, the tapping therapy with plum blossom needle was applied to the key points, named Jianyu (LI 15), Jianliao (LI 14), Jianzhen (SI 9), Hegu (LI 4), Chengfu (BL 36), Zusanli (ST 36), Xiyangguan (GB 33), etc. The treatment was given for 15 min each time, once a day. Before treatment, after 4 and 8 weeks of treatment, the Fugl-Meyer assessment (FMA) and Barthel index (BI) were adopted to evaluate the motor function of the extremity and the activity of daily life in the patients of the two groups separately. The modified Ashworth scale was used to evaluate the effect of anti-spasticity. In 4 and 8 weeks of treatment, FMA: scores and BI scores were all significantly increased as compared with those before treatment in the two groups: (both P<0. 05). The results in 8 weeks of treatment in the observation group were significantly better than those in the control group (all P<0. 05). In 4 and 8 weeks of treatment, the scores of spasticity state were improved as compared with those before treatment in the patients of the two groups (all P<0. 05). The result in 8 weeks of treatment in the observation group was significantly better than that in the control group (P<0. 05). In 8 weeks of treatment, the total effective rate of anti-spasticity was 90. 0% (36/40) in the observation group, better than 75. 0% (30/40) in the control group (P<0. 05). The tapping therapy with plum blossom needle at the key points combined with Bobath therapy effectively relieves hemiplegic spasticity in the patients of cerebral infarction and improves the motor function of extremity and the activity of daily life.

To evaluate whether electro-acupuncture (EA) treatment at acupoints of Zusanli (ST 36) and Quchi (LI 11) could reduce motor impairments and enhance brain functional recovery in rats with ischemic stroke. A rat model of middle cerebral artery occlusion (MCAO) was established. EA at ST 36 and LI 11was started at 24 hours (MCAO + EA group) after ischemic stroke. The nontreatment (MCAO) and sham-operated control (SC) groups were included as controls. The neurologic deficits of all groups were assessed by Zea Longa scores and the modified neurologic severity scores on 24 hours and 8 days after MCAO. To further investigate the effect of EA on infract volume and brain function, magnetic resonance imaging was used to estimate the brain lesion and brain neural activities of each group at 8 days after ischemic stroke. Within 1 week after EA treatment, the neurologic deficits were significantly alleviated, and the cerebral infarctions were improved, including visual cortex, motor cortex, striatum, dorsal thalamus, and hippocampus. Furthermore, whole brain neural activities of auditory cortex, lateral nucleus group of dorsal thalamus, hippocampus, motor cortex, orbital cortex, sensory cortex, and striatum were decreased in MCAO group, whereas that of brain neural activities were increased after EA treatment, suggesting these brain regions are in accordance with the brain structure analysis. EA at ST 36 and LI 11 could enhance the neural activity of motor function-related brain regions, including motor cortex, dorsal thalamus, and striatum in rats, which is a potential treatment for ischemia stroke.

Background. Immunotherapy has proven to be an useful tool in the management of allergic respiratory diseases; however, little has been studied in atopic dermatitis. Objective. To evaluate the clinical and immunological impact of immunotherapy with mites allergen extracts in atopic dermatitis. Methods. Patients with atopic dermatitis were assigned with computer-generated randomization to either of the following groups: (a) controls received only topical treatment with steroids and/or tacrolimus and (b) actively treated patients received topical treatment plus immunotherapy. Levels of serum total IgE, mites-specific IgE and IgG4 were assessed at study start and after one year of immunotherapy. Results. 31 patients in the active group and 29 in the control group completed the study. Symptoms and medication scores were significantly reduced in the active group after six months. Three patients in the control group showed new sensitizations to mites, while 3 patients in the active group showed neosensitization to shrimp with negative oral food challenge. We observed significant increase of mites-specific IgG4 levels in active group. Conclusion. Specific allergen immunotherapy induced a tolerogenic IgG4 response to mite allergens associated with favorable clinical effects in atopic dermatitis patients. PMID:23724240

2005-06-01

The use of extracorporeal shock wave therapy for the treatment of lateral epicondylitis is controversial. The purpose of this study was to evaluate the use of extracorporeal shock wave therapy without local anesthesia to treat chronic lateral epicondylitis. One hundred and fourteen patients with a minimum six-month history of lateral epicondylitis that was unresponsive to conventional therapy were randomized into double-blind active treatment and placebo groups. The protocol consisted of three weekly treatments of either low-dose shock wave therapy without anesthetic or a sham treatment. Patients had a physical examination, including provocation testing and dynamometry, at one, four, eight, and twelve weeks and at six and twelve months after treatment. Radiographs, laboratory studies, and electrocardiograms were also evaluated prior to participation and at twelve weeks. A visual analog scale was used to evaluate pain, and an upper extremity functional scale was used to assess function. Crossover to active treatment was initiated for nonresponsive patients who had received the placebo and met the inclusion criteria after twelve weeks. A total of 108 of the 114 randomized patients completed all treatments and the twelve weeks of follow-up required by the protocol. Sixty-one patients completed one year of follow-up, whereas thirty-four patients crossed over to receive active treatment. A significant difference (p = 0.001) in pain reduction was observed at twelve weeks in the intent-to-treat cohort, with an improvement in the pain score of at least 50% seen in 61% (thirty-four) of the fifty-six patients in the active treatment group who were treated according to protocol compared with 29% (seventeen) of the fifty-eight subjects in the placebo group. This improvement persisted in those followed to one year. Functional activity scores, activity-specific evaluation, and the overall impression of the disease state all showed significant improvement as well (p < 0.05). Crossover patients also showed significant improvement after twelve weeks of active treatment, with 56% (nineteen of thirty-four) achieving an improvement in the pain score of at least 50% (p < 0.0001). These results demonstrate that low-dose shock wave therapy without anesthetic is a safe and effective treatment for chronic lateral epicondylitis.

Autonomic nervous system imbalance is associated with metabolic diseases, including diabetes. Glibenclamide is an antidiabetic drug that acts by stimulating insulin secretion from pancreatic beta cells and is widely used in the treatment of type 2 diabetes. Since there is scarce data concerning autonomic nervous system activity and diabetes, the aim of this work was to test whether glibenclamide can improve autonomic nervous system activity and muscarinic acetylcholine receptor function in pre-diabetic obese male rats. Pre-diabetes was induced by treatment with monosodium L-glutamate in neonatal rats. The monosodium L-glutamate group was treated with glibenclamide (2 mg/kg body weight /day) from weaning to 100 days of age, and the control group was treated with water. Body weight, food intake, Lee index, fasting glucose, insulin levels, homeostasis model assessment of insulin resistance, omeostasis model assessment of β-cell function, and fat tissue accumulation were measured. The vagus and sympathetic nerve electrical activity were recorded. Insulin secretion was measured in isolated islets challenged with glucose, acetylcholine, and the selective muscarinic acetylcholine receptor antagonists by radioimmunoassay technique. Glibenclamide treatment prevented the onset of obesity and diminished the retroperitoneal (18%) and epididymal (25%) fat pad tissues. In addition, the glibenclamide treatment also reduced the parasympathetic activity by 28% and glycemia by 20% in monosodium L-glutamate-treated rats. The insulinotropic effect and unaltered cholinergic actions in islets from monosodium L-glutamate groups were increased. Early glibenclamide treatment prevents monosodium L-glutamate-induced obesity onset by balancing autonomic nervous system activity.

This study investigated the relationships among an enriched environment, stress levels, and drug addiction. Mice were divided randomly into four treatment groups (n=12 each): enriched environment without restraint stress (EN), standard environment without restraint stress (SN), enriched environment with restraint stress (ES), and standard environment with restraint stress (SS). Mice were reared in the respective environment for 45 days. Then, the ES and SS groups were subjected to restraint stress daily (2 h/day) for 14 days, whereas the EN and SN groups were not subjected to restraint stress during this stage. The stress levels of all mice were tested in the elevated plus maze immediately after exposure to restraint stress. After the 2-week stress testing period, mice were administered acute or chronic morphine (5 mg/kg) treatment for 7 days. Then, after a 7-day withdrawal period, the mice were injected with saline (1 ml/kg) or morphine (5 mg/kg) daily for 2 days to observe locomotor activity. The results indicated that the enriched environment reduced the stress and locomotor activity induced by acute morphine administration or saline after chronic morphine treatment. However, the enriched environment did not significantly inhibit locomotor activity induced by morphine challenge. In addition, the stress level did not mediate the effect of the enriched environment on drug-induced locomotor activity after acute or chronic morphine treatment.

This study aimed to elucidate the protective effect of minocycline against streptomycin-induced damage of cochlear hair cells and its mechanism. Cochlear membranes were isolated from newborn Wistar rats and randomly divided into control, 500μmol/L streptomycin, 100μmol/L minocycline, and streptomycin and minocycline treatment groups. Hair cell survival was analyzed by detecting the expression of 3-nitrotyrosine (3-NT) in cochlear hair cells by immunofluorescence and an enzyme-linked immunosorbent assay. Expression of 3-NT and inducible nitric oxide synthase (iNOS), and poly (ADP-Ribose) polymerase (PARP) and caspase-3 activation were evaluated by western blotting. The results demonstrated hair cell loss at 24h after streptomycin treatment. No change was found in supporting cells of the cochleae. Minocycline pretreatment improved hair cell survival and significantly reduced the expression of iNOS and 3-NT in cochlear tissues compared with the streptomycin treatment group. PARP and caspase-3 activation was increased in the streptomycin treatment group compared with the control group, and pretreatment with minocycline decreased cleaved PARP and activated caspase-3 expression. Minocycline protected cochlear hair cells from injury caused by streptomycin in vitro. The mechanism underlying the protective effect may be associated with the inhibition of excessive formation of nitric oxide, reduction of the nitration stress reaction, and inhibition of PARP and caspase-3 activation in cochlear hair cells. Combined minocycline therapy can be applied to patients requiring streptomycin treatment. Copyright © 2017. Published by Elsevier B.V.

As the backbone of highly active antiretroviral therapy (HAART), nucleoside reverse transcriptase inhibitors (NRTIs) have effectively improved outcomes for HIV-infected patients. However, long-term treatment with NRTIs can cause a series of pathologies associated with mitochondrial toxicity. To date, the status and mechanism of mitochondrial toxicity induced by NRTIs are still not clear, especially in HIV-infected children. As part of the national pediatric HAART program in China, our study focused on mitochondrial toxicity and its potential mechanism in HIV-1-infected children who were divided into two groups based on their duration of treatment with NRTIs: one group received treatment for less than 36 months and one group was treated for 36 to 72 months. The control group comprised age-matched non-HIV-infected children. Blood lactic acid and ATP levels in peripheral blood mononuclear cells (PBMCs) were measured to evaluate mitochondrial function, and mtDNA copies and mutations in PBMCs were determined for detecting mtDNA lesions. Simultaneously, TK2 and P53R2 gene expression in PBMC was measured. As compared with the control group, blood lactic acid levels in both NRTI treatment groups were significantly higher, whereas ATP levels and mtDNA mutation rates in PBMCs did not differ between the control and the two NRTI treatment groups. Both NRTI treatment groups exhibited significant mtDNA loss. N Moreover, we found that P53R2 mRNA expression and protein levels were significantly reduced in both treatment groups and that TK2 mRNA expression and protein levels were induced in the long-term NRTI treatment group. These results suggest that mitochondrial toxicity occurs in long-term HAART patients and that P53R2 and TK2 levels in PBMCs are useful biomarkers for detecting mitochondrial toxicity in patients on long-term treatment with NRTIs.

In order to investigate the relative efficacy and safety of zopiclone and zolpidem, we compared the effects of higher doses of zopiclone and zolpidem on the frequency of hippocampal theta activity and sleep structure with that of triazolam. Rats were divided into triazolam treatment group (1 mg/kg, 5 mg/kg), zopiclone treatment group (20 mg/kg, 100 mg/kg) and zolpidem treatment group (20 mg/kg, 100 mg/kg). Rats were injected intraperitoneally with these drugs or their vehicle. Polygraphic sleep recording and visual frequency analysis of the hippocampal EEG activity in REM sleep were carried out for 6 h after each injection. Zolpidem, unlike triazolam and zopiclone, had a much milder reducing-effect on the frequency of hippocampal theta activity and suppressing-effect on REM sleep. These results suggest that zolpidem may prove to be a safer hypnotic drug which has fewer or milder side effects than are benzodiazepine and cyclopyrrolone hypnotics.

Objective The purpose of this retrospective study was to investigate short-term and long-term skeletodental outcomes of Class III activator treatment. Methods A Class III activator treatment group (AG) comprised of 22 patients (9 boys, 13 girls) was compared with a Class III control group (CG) comprised of 17 patients (6 boys, 11 girls). The total treatment period was divided into three stages; the initial stage (T1), the post-activator treatment or post-mandibular growth peak stage (T2), and the long-term follow-up stage (T3). Cephalometric changes were evaluated statistically via the Mann-Whitney U-test and the Friedman test. Results The AG exhibited significant increases in the SNA angle, ANB angle, Wits appraisal, A point-N perpendicular, Convexity of A point, and proclination of the maxillary incisors, from T1 to T2. In the long-term follow-up (T1-T3), the AG exhibited significantly greater increases in the ANB angle, Wits appraisal, and Convexity of A point than the CG. Conclusions Favorable skeletal outcomes induced during the Class III activator treatment period were generally maintained until the long-term follow-up period of the post-mandibular growth peak stage.

This paper presents the results of a randomized, double-blind, placebo-controlled study of the efficacy of chlorpheniramine in relieving the symptoms and attenuating the pathophysiologic correlates of a rhinovirus "common cold." Forty healthy, adult, nonatopic subjects were randomly assigned to one of two treatment groups: active drug and placebo. On study Day 0, all subjects were challenged intranasally with rhinovirus type 39 (dose = 100 TCID50). Subjects were cloistered from Day 2 to Day 7, at which time they were treated with either chlorpheniramine or placebo. From 3 days before challenge to study Day 19, subjects had nasal patency assessed by rhinomanometry, eustachian tube function assessed by the 9-step test and sonotubometry, middle ear pressure assessed by tympanometry and nasal clearance assessed by the dyed-saccharin technique. Symptom diaries were maintained throughout the period of follow-up. During cloister, symptoms also were scored by interview, nasal secretions were quantified and nasal washings were performed for viral culture. Results showed that 19 (95%) subjects in the active-treatment group and 18 (90%) subjects in the placebo-treatment group shed virus. Symptomatic colds were observed in 63% of the active-treated and 83% of the placebo-treated subjects. Symptoms increased on Day 1 and peaked at Days 4 to 5. Detrimental changes in other measured functions consistent with those previously reported were observed. During the period of treatment, significant differences in the average symptom scores favoring the active-treatment group were observed for sneezing. Also, weight of expelled secretions was greater and mucociliary clearance rate less on some cloister days for the placebo-treated group. No significant differences between treatment groups in the objective measures of nasal congestion or the response of the middle ear and eustachian tube were documented.

To assess transversal tooth movements and buccal bone modeling of maxillary lateral segments achieved with active or passive self-ligating bracket systems in a randomized clinical trial. Sixty-four patients, with Class I, II, and mild Class III malocclusions, were randomly assigned to treatment with passive (Damon 3 MX) or active (In-Ovation R) SLBs. Impressions and cone-beam CT-scans were taken before (T0) and after treatment (T1). Displacement of maxillary canines, premolars and molars, and buccal alveolar bone modeling were blindly assessed. Twenty-one patients in the Damon and 20 in the In-Ovation group completed treatment according to the prescribed protocol. Eight Damon and 10 In-Ovation patients were excluded as the treatment approach had to be changed because of deviation from the recommended initial plan, while three Damon and two In-Ovation patients did not complete the treatment. Transversal expansion of the upper arch was achieved by buccal tipping in all but one patient in each group. No statistical significant difference in inter-premolar bucco-lingual inclination was found between the two groups from T0 to T1. The bone area buccal to the 2nd premolar decreased on average of 20% in the Damon and 14% in the In-Ovation group. Only few patients exhibited widening of the alveolar process. The anticipated translation and buccal bone modeling using active or passive SLBs could not be confirmed. Because of the large interindividual variation, a patient-specific analysis seems to be mandatory as individual factors like pre-treatment teeth inclination and occlusion influenced the treatment outcome of the individual patients. © 2011 Aarhus University A.

To explore the impacts on physical and mental health of the patients with polycystic ovary syndrome (PCOS) treated with electroacupuncture (EA) or Diane 35. Seventy-two patients of PCOS were randomized into an acupuncture group and a western medication group, 36 cases in each group. In the acupuncture group, acupuncture was applied to relieving liver stagnation and regulating qi activity at Ganshu (BL 18), Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 4), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3). After qi arrival, the electric stimulation was added for 30 min. Acupuncture treatment was given 3 times a week. In the western medication group, Diane 35 was taken since the 5th day of menstruation and lasted for 21 days. The cycle of treatment was 3 months in the two groups. Before treatment and at the end of treatment, the symptom scores were evaluated and the self-report symptom inventory, symptom checklist-90 (SCL-90) was used for the mental health evaluation and the comparison was made between the two groups. Compared with those before treatment in the same group, the symptom scores were reduced significantly after treatment in the two groups (both P <0.01). After treatment, the symptom scores in the acupuncture group were reduced significantly as compared with those in the western medicationgroup ( P <0.01). After treatment, the scores of somatization, interpersonal sensitivity, depression, anxiety and hostility were reduced significantly as compared with those before treatment in the acupuncture group (all P <0.05). After treatment, the scores of somatization, interpersonal sensitivity, depression, anxiety, hostility and phobic factor were lower significantly than those in the western medication group (all P <0.05). EA with relieving liver stagnation and regulating qi activity reduces the symptom scores of PCOS and SCL-90 scores, acting on regulating both physical and mental conditions. The effects achieved with acupuncture are better than those with Diane 35.

This study was conducted on Korean male high school soccer players who underwent anterior cruciate ligament reconstruction (ACLR) to identify the effects of an accelerated rehabilitation exercise (ARE) program on knee joint isometric strength, thigh circumference, Lysholm score, and active balance agility. We assigned eight test participants each to a physical therapy group (PTG) and an accelerated rehabilitation exercise group (AREG), and compared differences between the groups. Both the PTG and AREG showed significant increases in 30° away and 60° toward isometric strength after treatment. In addition, significant differences were observed in these strength tests between the two groups. Both groups also showed significant increases in thigh circumference, Lysholm score, and active balance agility after treatment, but no significant differences were observed between the two groups. We conclude that the ARE treatment was more effective for improving isometric strength of the knee joint than that of physical therapy, and that an active rehabilitation exercise program after ACLR had positive effects on recovery performance of patients with an ACL injury and their return to the playing field.

Functional effects of construction bite for activator (Andresen type) especially on lateral pterygoid muscle, as well as the positional changes of the mandible, hyoid bone and surface EMGs from bilateral anterior temporal (TA) and masseter (MM) muscle, were studied on the electric force scale, MKG, EMG and cephalometric radiographs in 14 subjects with anterior cross bite in mixed dentition. The cephalometric radiographs were taken at the start of each patient's treatment. One was taken with the mandible in the intercuspal position and one was also taken with the activator in the mouth at the overjet improvement. The activator patients were divided into two groups because of differences in the direction of movement of the hyoid bone in the FH plane. In group O (7 patients), the movement of the hyoid bone was at an oblique angle to the FH plane, while in group D (7 patients) the movement ot the hyoid bone with nearly direct below angle to FH plane. The patients were further divided into three types because of differences in the distance between the hyoid bone and mental spine, and combined with the groups OA (3 patients), OB (2 patients), OC (2 patients), DA (5 patients), DB (2 patients) and DC (Naught). The results obtained were as follows: The forces for the construction bite for groups O and D were 2.71 Kg and 2.72 kg, respectively. Type OC required significantly heavier force. (p less than 0.05) In the condylar test, O group was significantly smaller at the start of treatment, but not after overjet improvement. Type OA and OB were also significantly smaller at the start of treatment. (p less than 0.05) Velocity of opening for group D was significantly (p less than 0.05) faster at the start of treatment, but not after that. There was no significant difference in EMGs between the groups, with activator in the mouse D group much increased as it EMGs. The EMGs M/T ratio for both groups was approximately 100% at the start of treatment for overjet improvement. In cases with no or slight lateral shift in the recorded path of closure or in the incisal region, no large differences were recorded laterally. Large EMGs differences were recorded with lateral shift in the incisal region, especially when taking the construction bite.

A differential contribution of the right and left amygdalae to affective information processing has been proposed. However, the direction of this lateralization has not been confirmed. In this study, we used a pre- and post-treatment (escitalopram) design to analyze the relative differences between neural activity in the right and left amygdalae during exposure to emotional stimuli in currently depressed patients. To the best of our knowledge, this study is to compare neural activity between the left and right amygdalae in people with depression. Our findings could lead to the development of parameters or biomarkers for depressive symptoms and treatment response. We used a pre-post-test design without a control group. Twenty currently depressed participants underwent an emotion processing task during fMRI. These participants were then treated with an antidepressant for 6 weeks. We used amygdala region-of-interest analysis to evaluate the hemodynamic response during exposure to colored emotional pictures. In total, thirteen of the 20 participants were placed into a separate group based on degree of response to antidepressants. The partial response group had an averaged HDRS score of 10.75 ± 2.25 and an averaged DBOLDLR signal of 189.18 ± 140.23 (m1 = 8), and the remitted group had an averaged HDRS score of 4.80 ± 1.64 and an averaged DBOLDLR signal of 421.26 ± 109.19 (m2 = 5). Each individual had lateralized amygdala activity, and the direction of asymmetry persisted following treatment. Amygdala responses to four types of emotional stimuli did not significantly change (p > 0.05) with treatment in either the right or the left amygdala. However, the difference in neural activity between the right and left amygdalae was greater after treatment, and the variation in neural activity was larger in the left amygdala. We found that the response between the right and left amygdala did not differ in terms of time series, although activity increased after pharmaceutical treatment for each emotion tested. In the future, changes in BOLD signals as revealed by fMRI might be useful in evaluating the clinical manifestation of major depression.

To explore the clinical efficacy of early application of sequential gastrointestinal lavage in patients with acute paraquat poisoning by analyzing the clinical data of 97 patients. A total of 97 eligible patients with acute paraquat poisoning were divided into conventional treatment group (n = 48) and sequential treatment group (n = 49). The conventional treatment group received routine gastric lavage with water. Then 30 g of montmorillonite powder, 30 g of activated charcoal, and mannitol were given to remove intestinal toxins once a day for five days. The sequential treatment group received 60 g of montmorillonite powder for oral administration, followed by small-volume low-pressure manual gastric lavage with 2.5%bicarbonate liquid. Then 30 g of activated charcoal, 30 g of montmorillonite powder, and polyethylene glycol electrolyte lavage solution were given one after another for gastrointestinal lavage once a day for five days. Both groups received large doses of corticosteroids, blood perfusion, and anti-oxidation treatment. The levels of serum potassium, serum amylase (AMY) alanine aminotransferase (ALT), total bilirubin (TBIL), blood urea nitrogen (BUN), creatinine (Cr), lactate (Lac), and PaO₂of patients were determined at 1, 3, 5, 7, and 10 days. Laxative time, mortality, and survival time of dead cases were evaluated in the two groups. The incidence rates of hypokalemia (<3.5 mmol/L) and AMY (>110 U/L) were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). There were no significant differences in the incidence of ALT (>80 U/L), TBIL (>34.2 µmol/L), BUN (>7.2 mmol/L), and Cr (>177 µmol/L) between the two groups (P>0.05). However, the highest levels of ALT, TBIL, BUN, Cr, and Lac were significantly lower in the sequential treatment group than in the conventional treatment group (P < 0.05). Moreover, the sequential treatment group had significantly lower incidence of PaO₂(<60 mmHg), shorter average laxative time, lower mortality, and longer survival time of dead cases than the conventional treatment group (P < 0.05). The early application of sequential gastrointestinal lavage can shorten laxative time, alleviate organ damage in the liver, kidney, lung, and pancreas, reduce mortality, and prolong the survival time of dead cases in patients with acute paraquat poisoning.

Background: Whereas most studies have focused on euthanasia and physician-assisted suicide, few have dealt comprehensively with other critical interventions administered at the end of life. We surveyed cancer patients, family caregivers, oncologists and members of the general public to determine their attitudes toward such interventions. Methods: We administered a questionnaire to four groups about their attitudes toward five end-of-life interventions — withdrawal of futile life-sustaining treatment, active pain control, withholding of life-sustaining measures, active euthanasia and physician-assisted suicide. We performed multivariable analyses to compare attitudes and to identify sociodemographic characteristics associated with the attitudes. Results: A total of 3840 individuals — 1242 cancer patients, 1289 family caregivers and 303 oncologists from 17 hospitals, as well as 1006 members of the general Korean population — participated in the survey. A large majority in each of the groups supported withdrawal of futile life-sustaining treatment (87.1%–94.0%) and use of active pain control (89.0%–98.4%). A smaller majority (60.8%–76.0%) supported withholding of life-sustaining treatment. About 50% of those in the patient and general population groups supported active euthanasia or physician-assisted suicide, as compared with less than 40% of the family caregivers and less than 10% of the oncologists. Higher income was significantly associated with approval of the withdrawal of futile life-sustaining treatment and the practice of active pain control. Older age, male sex and having no religion were significantly associated with approval of withholding of life-sustaining measures. Older age, male sex, having no religion and lower education level were significantly associated with approval of active euthanasia and physician-assisted suicide. Interpretation: Although the various participant groups shared the same attitude toward futile and ameliorative end-of-life care (the withdrawal of futile life-sustaining treatment and the use of active pain control), oncologists had a more negative attitude than those in the other groups toward the active ending of life (euthanasia and physician-assisted suicide).

Many traumatized refugees experience both posttraumatic stress disorder and chronic pain. Based on Mutual Maintenance Theory and the Perpetual Avoidance Model, this study examined the additional effect of physical activity within a biofeedback-based cognitive behavioral therapy (CBT-BF) for traumatized refugees. In a controlled design, 36 patients were randomized into one of three conditions (CBT-BF, CBT-BF with physical activity [CBT-BF+active], and a waiting list control group [WL]). Thirty patients (n=10 in each group) completed the treatment and a follow-up assessment 3 months later. Participants' coping strategies, pain and mental health status, and physiological reactivity were assessed before and after the intervention and at 3-month follow-up. Treatment effects were analyzed using analyses of variance with baseline scores as covariates (ANCOVAs) and the Reliable Change Index. The CBT-BF and CBT-BF+active groups showed improvements in all outcome measures relative to the WL group. The effect sizes for the main outcome measures were higher in the CBT-BF+active group than in the CBT-BF group. Repeated measures analyses of covariance showed significant group effects for coping strategies--in particular, for the "cognitive restructuring" and "counter-activities" subscales as well as a marginally significant group effect for "perceived self-competence"--with the CBT-BF+active group showing more favorable outcomes than the CBT-BF group. Moreover, 60% of participants in the CBT-BF+active group showed clinically reliable intraindividual change in at least one subscale of the pain coping strategies questionnaire, compared with just 30% of participants in the CBT-BF group. Findings of improved coping strategies, larger effect sizes, and higher rates of clinical improvement in the CBT-BF+active group suggest that physical activity adds value to pain management interventions for traumatized refugees. Given the small sample size, however, these preliminary results need replication in a larger trial. Wiley Periodicals, Inc.

To observe the effectiveness and safety of external applying Compound Tripterygium wilfordii Hook F. (TwHF) in relieving joint pain in rheumatoid arthritis (RA) patients. In this double-blinded, randomized multicenter trial, a total of 174 moderately active RA patients were enrolled and randomly assigned to the treatment group (treated with Compound TwHF, 87 cases) and the placebo control group (87 cases). Compound TwHF or placebo was externally applied in painful joints, 20 g each time, once per day for 8 weeks. Self-reported joint pain relief was taken as a primary effective indicator. Visual analogue scale for pain (VAS), disease activity score of 28 joints (DAS28), VAS for general health (GH) were evaluated before treatment, at week 4 and after treatment. Erythrocyte sedimentation rate (ESR) and hypersensitive C reactive protein (hs-CRP) were tested before and after treatment. Menstrual changes in females were observed during treatment. Skin irritation occurred during the recording process was assessed using skin irritation strength. Intention to treat (ITT) was statistically analyzed. The joint pain relief rate in the treatment group was 90.8% (79/87 cases), higher than that in the placebo control group (69.0%, 60/87 cases; P = 0.001). VAS pain score, DAS28, VAS for GH score were significantly improved in the two groups at week 4 of treatment and after treatment, as compared with before treatment (P < 0.01). ESR and hs-CRP levels significantly decreased in the treatment group after treatment (P < 0.05, P < 0.01). No difference was found in post-treatment VAS pain score, DAS28, VAS for GH score, ESR, or hs-CRP between the two groups (P > 0.05). Eight adverse events occurred in the treatment group (5 skin allergy, 1 intolerance of medical odor, and 2 mild liver injury), while 3 adverse events occurred in the placebo control group (2 skin allergy, 1 mild liver injury). There was no statistical difference in adverse event between the two groups (P > 0.05). No menstrual change occurred in the treatment group. External applying Compound TwHF was an effective and safe way to relieve-joint pain of RA patients, which could be taken as an adjuvant therapy.

Randomized controlled trial. Participants were assigned to 2 groups: MT and PNF. 30 min' sessions were performed once a week for three weeks. Three evaluations were performed: basal, one-week and four-weeks post-treatment. University of Valencia (Spain). 22 in MT group and 20 in PNF group. Dynamic Balance, measured with Star Excursion Balance Test; Active Range of Motion (ROM), using a manual goniometer and Lumbar Flexibility, assessed with Fingertip-to-floor test. Both groups significantly improved in lateral and medial dynamic balance one-week post-treatment (p < 0.05); but the improvement in the MT group lasted until the fourth-week after treatment in both reaches (lateral and medial) (p < 0.05). MT group also obtained significant improvements in dorsal flexion of the ankle in the fourth-week post-treatment (p < 0.05) and in lumbar flexibility one-week post-treatment (p < 0.05). MT and PNF improve dynamic balance one-week post-treatment; however, the improvement obtained through MT is maintained four-weeks later. Only MT improves dorsal flexion of the ankle four-weeks post-treatment and lumbar flexibility one-week post-treatment. Copyright © 2018 Elsevier Ltd. All rights reserved.

New learning and memory deficits are common following traumatic brain injury (TBI). Yet few studies have examined the efficacy of memory retraining in TBI through the most methodologically vigorous randomized clinical trial. Our previous research has demonstrated that the modified Story Memory Technique (mSMT) significantly improves new learning and memory in multiple sclerosis. The present double-blind, placebo-controlled, randomized clinical trial examined changes in cerebral activation on functional magnetic resonance imaging following mSMT treatment in persons with TBI. Eighteen individuals with TBI were randomly assigned to treatment (n = 9) or placebo (n = 9) groups. Baseline and follow-up functional magnetic resonance imaging was collected during a list-learning task. Significant differences in cerebral activation from before to after treatment were noted in regions belonging to the default mode network and executive control network in the treatment group only. Results are interpreted in light of these networks. Activation differences between the groups likely reflect increased use of strategies taught during treatment. This study demonstrates a significant change in cerebral activation resulting from the mSMT in a TBI sample. Findings are consistent with previous work in multiple sclerosis. Behavioral interventions can show significant changes in the brain, validating clinical utility.

Physical activity may improve chronic pain, anxiety, and depression, which are prevalent among patients in methadone maintenance treatment (MMT), but relatively little is known about the physical activity levels or interest in exercise of patients in MMT. We used a brief self-report instrument to assess physical activity levels, chronic pain, psychiatric distress, and interest in exercise group participation among 303 adults seeking MMT. Most (73%) reported no moderate or vigorous intensity physical activity in the past week; 27% met recommended physical activity levels, and 24% reported interest in exercise group participation. Participants with (compared to those without) chronic pain had higher levels of psychiatric distress and were less likely to meet recommended levels of physical activity (p < .05), but did not differ significantly in their interest in participating in an exercise group. Participants who met recommended levels of physical activity in the past week were more likely to be men and had lower levels of depression than others (p < .05). Low levels of physical activity and low interest in exercise group participation among patients entering MMT point to the need for and likely challenges of implementing exercise interventions in MMT. © American Academy of Addiction Psychiatry.

This study is to evaluate the effect of laser activation on the whitening and crystalline structure of enamel surface during whitening treatment with hydrogen peroxide. Bovine teeth were treated with whitening gel containing 35% hydrogen peroxide. A whitening gel was applied on the enamel surface for a period of 5 min, and then irradiated using a diode laser (740 nm) during whitening treatment for 0, 30, 60, 120 and 180s for the GL0-W, GL30-W, GL60-W, GL120-W and GL180-W groups, respectively. The total whitening application time was 30 min for all groups. Laser-irradiated enamel groups showed a similar lightness compared to the GL0-W group. The thickness of porous layer observed on the enamel surface of GL0-W group was decreased by increasing the laser irradiation time. While the Ca and P contents of the GL0-W group were lower than those of the non-whitening treated group (GL0-C), the Ca and P contents of the GL180-W group were similar to those of the GL180-C group. The enamel crystallinity was dramatically decreased by whitening treatment without laser irradiation. However, the decrease of crystallinity was protected by laser irradiation during whitening treatment. Raman measurement verified that laser irradiation could prevent the loss of mineral compositions on enamel and maintain its crystalline structure. The professional whitening treatment with hydrogen peroxide and diode laser activation improves not only the whitening effect but also protects the change of enamel structure compared to the treatment with only gel.

Background/aim: The aim of this research is to investigate the clinical efficacy of hemoperfusion in the treatment of severe acute organophosphorus pesticide poisoning (AOPP). Materials and methods: Patients meeting the inclusion criteria were divided into Groups 1 and 2 according to whether hemoperfusion was applied or not. Group 2 was observed as the control group. Conventional therapy for AOPP was given to Groups 1 and 2. Besides conventional treatment, patients in Group 1 were also treated with hemoperfusion therapy. Cholinesterase activity and blood glucose concentration were tested before hemoperfusion and for the first 3 days afterwards. The recovery time of 50% cholinesterase was recorded. At the same time, the incidence and mortality of intermediate syndrome was observed and compared. Results: The incidence and mortality of intermediate syndrome in Group 1 was obviously decreased, and the recovery time of cholinesterase activity was significantly shortened compared with Group 2. Conclusion: Hemoperfusion, used for treating severe AOPP, contributes to the improvement of cholinesterase activity, low incidence and mortality of intermediate syndrome, and increase in curative rate.

The RhoA/Rho-associated kinase (ROCK) pathway has a key physiological role in the pathogenesis of atherosclerosis. Increased ROCK activity is associated with cardiovascular diseases. Endogenous nitric oxide (NO) has an anti-atherosclerotic effect, whereas the exogenous NO-mediated cardiovascular effect still remains controversial. The purpose of this study was to evaluate the effect of exogenous NO on ROCK activity in patients with angina pectoris. This is a prospective, open-label, randomized, controlled study. A total of 30 patients with angina pectoris were randomly assigned to receive 40 mg day−1 of isosorbide mononitrate (n = 15, 12 men and 3 women, mean age of 63 ± 12 years, isosorbide mononitrate group) or conventional treatment (n = 15, 13 men and 2 women, mean age of 64 ± 13 years, control group) for 12 weeks. ROCK activity in peripheral leukocytes was measured by western blot analysis. ROCK activities at 4 and 12 weeks after treatment were decreased in the isosorbide mononitrate group (0.82 ± 0.33 at 0 week, 0.62 ± 0.20 at 4 weeks, 0.61 ± 0.19 at 12 weeks, n = 15 in each group, P < 0.05, respectively) but not altered in the control group. ROCK1 and ROCK2 expression levels were similar in all treatment periods in the two groups. These findings suggest that the administration of exogenous NO can inhibit ROCK activity, indicating that the usage of exogenous NO could have a protective effect in patients with angina pectoris.

Treatments for chronic pain in persons with spinal cord injury (SCI) have been less than effective. Cranial electrotherapy stimulation (CES), a noninvasive technique that delivers a microcurrent to the brain via ear clip electrodes, has been shown to effectively treat several neurological and psychiatric disorders. The present study examined the effects of daily 1-hour active CES or sham CES treatment (randomly assigned) for 21 days on pain intensity and interference with activities in 38 males with SCI. The active CES group (n = 18) reported significantly decreased daily pain intensity compared with the sham CES group (n = 20) (mean change: active CES = -0.73, sham CES = -0.08; p = 0.03). Additionally, the active CES group reported significantly decreased pain interference (-14.6 pre- vs postintervention, p = 0.004) in contrast to the nonsignificant decrease in the sham CES group (-4.7 pre- vs postintervention, p = 0.24). These results suggest that CES can effectively treat chronic pain in persons with SCI.

Background/Objectives: Our objective was to investigate effects of an oral nutritional supplement containing n-3 polyunsaturated fatty acids (FAs) on quality of life, performance status, handgrip strength and physical activity in patients with non-small cell lung cancer (NSCLC) undergoing multimodality treatment. Subjects/Methods: In a double-blind experiment, 40 patients with stage III NSCLC were randomised to receive 2 cans/day of a protein- and energy-dense oral nutritional supplement containing n-3 polyunsaturated FAs (2.02 g eicosapentaenoic acid+0.92 g docosahexaenoic acid/day) or an isocaloric control supplement, during multimodality treatment. Quality of life, Karnofsky Performance Status, handgrip strength and physical activity (by wearing an accelerometer) were assessed. Effects of intervention were analysed by generalised estimating equations. P-values <0.05 were regarded as statistically significant. Results: The intervention group reported significantly higher on the quality of life parameters, physical and cognitive function (B=11.6 and B=20.7, P<0.01), global health status (B=12.2, P=0.04) and social function (B=22.1, P=0.04) than the control group after 5 weeks. The intervention group showed a higher Karnofsky Performance Status (B=5.3, P=0.04) than the control group after 3 weeks. Handgrip strength did not significantly differ between groups over time. The intervention group tended to have a higher physical activity than the control group after 3 and 5 weeks (B=6.6, P=0.04 and B=2.5, P=0.05). Conclusion: n-3 Polyunsaturated FAs may beneficially affect quality of life, performance status and physical activity in patients with NSCLC undergoing multimodality treatment. PMID:22234041

Purpose As adjuvant therapy for enhancing the effects of stimulants and thereby minimizing medication doses, we hypothesized that aerobic exercise might be an effective adjunctive therapy for enhancing the effects of methylphenidate on the clinical symptoms, cognitive function, and brain activity of adolescents with attention deficit hyperactivity disorder (ADHD). Methods Thirty-five adolescents with ADHD were randomly assigned to one of two groups in a 1/1 ratio; methylphenidate treatment + 6-wk exercise (sports-ADHD) or methylphenidate treatment + 6-wk education (edu-ADHD). At baseline and after 6 wk of treatment, symptoms of ADHD, cognitive function, and brain activity were evaluated using the Dupaul attention deficit hyperactivity disorder rating scale–Korean version (K-ARS), the Wisconsin Card Sorting Test, and 3-T functional magnetic resonance imaging, respectively. Results The K-ARS total score and perseverative errors in the sports-ADHD group decreased compared with those in the edu-ADHD group. After the 6-wk treatment period, the mean β value of the right frontal lobe in the sports-ADHD group increased compared with that in the edu-ADHD group. The mean β value of the right temporal lobe in the sports-ADHD group decreased. However, the mean β value of the right temporal lobe in the edu-ADHD group did not change. The change in activity within the right prefrontal cortex in all adolescents with ADHD was negatively correlated with the change in K-ARS scores and perseverative errors. Conclusions The current results indicate that aerobic exercise increased the effectiveness of methylphenidate on clinical symptoms, perseverative errors, and brain activity within the right frontal and temporal cortices in response to the Wisconsin card sorting test stimulation.

Objective Some previous studies have found clinical benefit of dual antiplatelet therapy with aspirin and cilostazol for prevention of secondary stroke, but the physiological mechanism involved remains unknown. We aimed to clarify the effects of aspirin/cilostazol therapy on the platelet and endothelial functions of patients with acute noncardioembolic ischemic stroke, in comparison to patients who were treated with aspirin alone. Methods The present randomized prospective pilot study enrolled 24 patients within a week after the onset of noncardioembolic ischemic stroke. The patients were randomly allocated to receive aspirin (100 mg/day) (A group; 11 patients) or cilostazol (200 mg/day) plus aspirin (100 mg/day) (CA group; 13 patients). We measured platelet aggregation, platelet activation, and the thrombomodulin (TM), highly sensitive C-reactive protein (hs-CRP), intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1) and von Willebrand (vWF) antigen levels and vWF activity over a 4-week period after enrollment. Results There was no significant difference in the platelet functions of the A and CA groups. However, the platelet aggregation induced by adenosine diphosphate (ADP) was decreased at 2 and 4 weeks (p<0.05) after treatment in comparison to the pre-treatment values in the CA group, but not in the A group. Platelet activation, and the hs-CRP, TM, ICAM-1, VCAM-1 and vWF values did not significantly decrease after treatment in either group. Conclusion Although there were no significant differences in platelet aggregation, platelet activation or the endothelial biomarker levels of the A and CA groups, dual therapy with aspirin and cilostazol inhibited platelet aggregation in comparison to the pre-treatment values, similarly to patients who received aspirin alone. This may suggest the clinical usefulness of dual therapy with aspirin and cilostazol in the treatment of patients with noncardioembolic ischemic stroke.

To evaluate the clinical effect of manipulation on external humeral epicondylitis, and to explore the functional mechanism and ideal treatment. Eighty-six patients who had been treated with acupuncture, obturation and needle-knife were divided into routine group and treatment group randomly. In routine group, there were 42 cases (male 13, female 29, means 40.8 years); and in treatment group there were 44 cases (male 16, female 28, means 41.2 years). There's no further treatment for the routine group after the therapy above, while the treatment group was added with back-rotation traction manipulation. Taking Verhaar therapy effect appraisal system of tennis-ball elbow to evaluate elbow function. After 7 days of therapy, the results were excellent in 13 cases, good in 16, fair in 4, poor in 9 in the routine group; and excellent in 38, good in 4 and fair in 2 in treatment group; and the effect in the treatment group were better than that of the routine group (P < 0.010). Half a year later, in the routine group 38 cases recurrenced and in the treatment group 10 cases recurrenced. Making manipulation after routine acupuncture, local obturation and needle-knife has active meaning to remove trauma inflammation, prevent re-conglutination, promote recovery and prevent recurrence.

Describe the results from arthroscopic surgical treatment on a group of patients who developed symptoms after repetitive physical activity of moving their hips in a position of hyperflexion, as in leg presses and squats. The study group comprised 47 individuals (48 hips) who developed the onset of painful symptoms associated with hip hyperflexion exercises (leg presses or squats) and underwent arthroscopic treatment. The patients were evaluated radiographically and clinically according to the "Harris Hip Score", as modified by Byrd (MHHS), pre and postoperatively, and were asked about their return to sports activities and the surgical findings. The mean preoperative and postoperative MHHS, respectively, were 60 points (SD 11.0, range 38.5 to 92.4) and 95.9 points (SD 7.7, range 63.8 to 100), with an increase of 35.9 points (P < 0.001). Regarding physical activity, 30 individuals (71.5%) resumed sports activities after surgery, and 25 of them (83.4%) at the previous level. Six patients (12.8%) did not resume activities because of persistent pain. During arthroscopy, 48 hips (100%) presented lesions of the acetabular labrum, and 41 hips (85.4%) had acetabular chondral lesions. The patients with painful symptoms after hip hyperflexion exercises associated with femoroacetabular impingement presented improvements after arthroscopic treatment.

This study examined the influence of treatment motivation on posttreatment effectiveness of an outpatient, individual social skills training for juvenile delinquents imposed as a penal sanction. Propensity score matching was used to match a control group of juveniles receiving treatment as usual (n = 108 of total N = 354) to a treatment group of juveniles receiving Tools4U, a social skills training with a parental component (N = 115). Treatment motivation was examined as a moderator and predictor of treatment effects on impulsivity, social perspective-taking, social problem-solving, lack of critical reasoning, developmental task-related skills, and parenting skills. Treatment effects were mostly consistent across juveniles with different levels of treatment motivation. Only one moderating effect was found on active tackling (i.e., actively addressing problems), and predictive effects were found on seeking social support, cognitive empathy, hostile intent attribution, and self-centeredness. Implications for further research are discussed. PMID:27225504

Dehydroepiandrosterone (DHEA) has a fat-reducing effect, while little information is available on whether DHEA regulates glucose metabolism, which would in turn affect fat deposition. To investigate the effects of DHEA on glucose metabolism, rats were administered a high-fat diet containing either 0 (HCG), 25 (HLG), 50 (HMG), or 100 (HHG) mg·kg-1 DHEA per day via gavage for 8 weeks. Results showed that long-term administration of DHEA inhibited body weight gain in rats on a high-fat diet. No statistical differences in serum glucose levels were observed, whereas hepatic glycogen content in HMG and HHG groups and muscle glycogen content in HLG and HMG groups were higher than those in HCG group. Glucokinase, malate dehydrogenase and phosphofructokinase-2 activities in HMG and HHG groups, pyruvate kinase and succinate dehydrogenase activities in HMG group, and pyruvate dehydrogenase activity in all DHEA treatment groups were increased compared with those in HCG group. Phosphoenolpyruvate carboxykinase and glycogen phosphorylase mRNA levels were decreased in HMG and HHG groups, whereas glycogen synthase-2 mRNA level was increased in HMG group compared with those in HCG. The abundance of Glut2 mRNA in HMG and HHG groups and Glut4 mRNA in HMG group was higher than that in HCG group. DHEA treatment increased serum leptin content in HMG and HHG groups compared with that in HCG group. Serum insulin content and insulin receptor mRNA level in HMG group and insulin receptor substrate-2 mRNA level in HMG and HHG group were increased compared with those in HCG group. Furthermore, Pi3k mRNA level in HMG and Akt mRNA level in HMG and HHG groups were significantly increased than those in HCG group. These data showed that DHEA treatment could enhance glycogen storage and accelerate glucose catabolism in rats fed a high-fat diet, and this effect may be associated with the activation of PI3K/Akt-PFK-2 signaling pathway.

The present study aimed to determine a non-invasive nocturnal lighting system for the behavioural observation of a highly light sensitive species, Senegalese sole (Solea senegalensis). Locomotor activity, four types of behaviour and plasma melatonin were analysed in groups of 12 adult Senegalese sole (Solea senegalensis) reared in captivity and held under four night illumination treatments: total darkness (control), high 50lux intensity red light (group RH), low 5lux intensity red light (group RL) and infrared light (group IR). All groups experienced the same conditions during the day (lights on from 07:00 to 19:00) with white lighting of 125lux. Clarity of video images taken at night for the observation of fish behaviour were ranked as follows: group RH>RL>IR>control. All treatments presented a daily rhythm in locomotor activity with high activity from 14:00 to 18:00 and low activity from 21:00 to 12:00. The sole exposed to the high intensity red light at night appeared to be disturbed as during the low nocturnal locomotor activity period group RH presented higher activity and significantly higher nocturnal behaviour related to escape or fear than was observed in the other groups. The groups control, RL and IR exhibited similar levels of nocturnal locomotor activity and nocturnal behaviour related to escape or fear. Plasma melatonin, at mid-dark was not significantly different between the control and groups RL and IR, while melatonin was significantly lower in group RH compared to the control. The authors recommended low intensity red night illumination for the non-invasive study of nocturnal behaviour of Senegalese sole adults. Copyright © 2013 Elsevier Inc. All rights reserved.

Real-time functional magnetic resonance imaging neurofeedback can reduce striatal cue-reactivity to alcohol stimuli.

It has been shown that in alcoholic patients, alcohol-related cues produce increased activation of reward-related brain regions like the ventral striatum (VS), which has been proposed as neurobiological basis of craving. Modulating this activation might be a promising option in the treatment of alcohol addiction. One approach might be real-time functional magnetic resonance imaging neurofeedback (rtfMRI NF). This study was set up to implement and evaluate a rtfMRI approach in a group of non-addicted heavy social drinkers. Thirty-eight heavy drinking students were assigned to a real feedback group (rFB, n = 13), a yoke feedback group (yFB, n = 13) and a passive control group (noFB, n = 12). After conducting a reward task as functional localizer to identify ventral striatal regions, the participants viewed alcohol cues during three NF training blocks in a 3 T MRI scanner. The rFB group received feedback from their own and the yFB from another participants' VS. The noFB group received no feedback. The rFB and the yFB groups were instructed to downregulate the displayed activation. Activation of the VS and prefrontal control regions was compared between the groups. We found significant downregulation of striatal regions specifically in the rFB group. While the rFB and the yFB groups showed significant activation of prefrontal regions during feedback, this activation was only correlated to the reduction of striatal activation in the rFB group. We conclude that rtfMRI NF is a suitable method to reduce striatal activation to alcohol cues. It might be a promising supplement to the treatment of alcoholic patients. © 2015 Society for the Study of Addiction.

The aim of the study was to evaluate the therapeutic effect of electro-acupuncture (EA) and hydrotherapy, both in combination with patient education or with patient education alone, in the treatment of osteoarthritis in the hip. Forty-five patients, aged 42-86 years, with radiographic changes consistent with osteoarthritis in the hip, pain related to motion, pain on load, and ache were chosen. They were randomly allocated to EA, hydrotherapy, both in combination with patient education, or patient education alone. Outcome measures were the disability rating index (DRI), global self-rating index (GSI), and visual analogue scale (VAS). Assessments were done before the intervention and immediately after the last treatment and 1, 3, and 6 months after the last treatment. Pain related to motion and pain on load was reduced up to 3 months after last the treatment in the hydrotherapy group and up to 6 months in the EA group. Ache during the day was significantly improved in both the EA and hydrotherapy group up to 3 months after the last treatment. Ache during the night was reduced in the hydrotherapy group up to 3 months after the last treatment and in the EA group up to 6 months after. Disability in functional activities was improved in EA and hydrotherapy groups up to 6 months after the last treatment. Quality of life was also improved in EA and hydrotherapy groups up to 3 months after the last treatment. There were no changes in the education group alone. In conclusion, EA and hydrotherapy, both in combination with patient education, induce long-lasting effects, shown by reduced pain and ache and by increased functional activity and quality of life, as demonstrated by differences in the pre- and post-treatment assessments.

The purpose of this study was to examine the effects of aromatherapy on stress responses, autonomic nervous system (ANS) activity, and blood pressure in patients hospitalized to receive coronary angiography (CAG). A non-equivalent control group with a pretest-posttest design was used. The subjects were patients admitted to the day angiography room to receive CAG at E University Hospital (34 in the experimental group and 30 in the control group). The experimental group treatment was inhalation of the aroma oil blended with lavender, ylang-ylang, and neroli at a ratio of 4:2:1 twice before and after CAG. The measurements of stress index, ANS activity, and blood pressure were performed 5 times as follows: at admission, at pre-CAG after treatment I, at post-CAG, 2 hours after treatment II, and 4 hours after treatment II. The data were analyzed using the Mann-Whitney U Test and repeated-measures analysis of variance. Significant interactions in the high frequency of ANS (F=5.58, p=.005) were observed between group and time. Stress index (z=2.14, p=.016), systolic blood pressure (z=4.14, p<.005), and diastolic blood pressure (z=3.28, p=.001) were significantly different between the experimental and control groups after 4 hours of treatment II. The findings showed that aromatherapy was not effective before CAG, but was effective after CAG. Therefore, aromatherapy can be used as a nursing intervention for patients receiving CAG. © 2018 Korean Society of Nursing Science.

Aims The aim of this study was to investigate the effect of juggling therapy for anxiety disorder patients. Design and Method Subjects were 17 female outpatients who met the DSM-IV diagnostic criteria for anxiety disorders. Subjects were treated with standard psychotherapy, medication and counseling for 6 months. For the last 3 months of treatment, subjects were randomized into either a non-juggling group (n = 9) or a juggling therapy group (juggling group: n = 8). The juggling group gradually acquired juggling skills by practicing juggling beanbags (otedama in Japan) with both hands. The therapeutic effect was evaluated using scores of psychological testing (STAI: State and Trate Anxiety Inventry, POMS: Profile of Mood Status) and of ADL (FAI: Franchay Activity Index) collected before treatment, 3 months after treatment (before juggling therapy), and at the end of both treatments. Results After 6 months, an analysis of variance revealed that scores on the state anxiety, trait anxiety subscales of STAI and tension-anxiety (T-A) score of POMS were significantly lower in the juggling group than in the non-juggling group (p < 0.01). Depression, anger-hostility scores of POMS were improved more than non-jugglers. In the juggling group, activity scores on the vigor subscale of POMS and FAI score were significantly higher than those in the non juggling group (p < 0.01). Other mood scores of POMS did not differ between the two groups. Conclusion These findings suggest that juggling therapy may be effective for the treatment of anxiety disorders. PMID:17470298

Background Research increasingly supports a transdiagnostic conceptualization of emotional disorders (ie applying the same underlying treatment principles across mental disorders, without tailoring the protocol to specific diagnoses), and many international researchers are currently investigating this issue. Objective The aim of this study was to evaluate the efficacy and acceptability of a Web-based transdiagnostic program using a sample of Romanian adults diagnosed with anxiety and/or depression. Methods Volunteer participants registered for the study and completed a series of online self-report measures. Participants who fulfilled basic inclusion criteria on these measures were contacted for a telephone diagnostic interview using the Structural Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, 4th Edition Axis I Disorders (SCID-I). Enrolled participants were randomized to either the active treatment group (N=69) or the wait-list control group (N=36) using a 2:1 ratio. The transdiagnostic treatment was based on the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP; Barlow et al, 2011) that addresses common underlying mechanisms of anxiety and depression. Participants randomized to the active treatment condition received 10 weeks of Web-based treatment based on the UP. Throughout treatment, graduate students in clinical psychology provided guidance that consisted of asynchronous written communication on a secure Web platform. After the intervention, participants in both study conditions were invited to complete a set of self-report measures and a postintervention SCID-I interview conducted by a different team of graduate students blinded to participants’ group and diagnostic status. Six months later, participants in the active treatment group were invited to complete an online follow-up assessment. Results During the intervention, active treatment participants completed on average 19 homework assignments (SD 12.10), and we collected data from 79.0% (83/105) at postintervention and 51% (35/69) at follow-up for self-report measures. Postintervention SCID-I interviews were collected from 77.1% (81/105) participants. Relative to the wait-list control group, the transdiagnostic intervention yielded overall medium to large effect sizes for the primary outcome measures (within-group Hedges g=0.52-1.34 and between-group g=0.39-0.86), and also for anxiety sensitivity (g=0.80), symptom interference (g=0.48), and quality of life (g=0.38). Significant within-groups effects only were reported for the active treatment group on Panic Disorder Severity Scale-Self Report (PDSS-SR, g=0.58-0.65) and Yale-Brown Obsessive Compulsive Scale (Y-BOCS, g=0.52-0.58). Conclusions Insignificant between-group differences for the Y-BOCS and PDSS-SR could be explained by the small number of participants with the associated primary diagnostic (eg, only 3 participants with obsessive compulsive disorder) by the choice of outcome measure (PDSS-SR was not rated among the evidence-based measures) and by the fact that these disorders may be more difficult to treat. However, the overall results suggest that the transdiagnostic intervention tested in this study represents an effective treatment option that may prove easier to disseminate through the use of Web-based delivery systems.

Biofeedback with or without combined autogenic training is known to be effective for the treatment of migraine. This study aimed to examine the effect of biofeedback treatment on headache activity, anxiety, and depression in Korean female patients with migraine headache. Patients were randomized into the treatment group (n=17) and monitoring group (n=15). Mood states including anxiety and depression, and psychophysiological variables such as mean skin temperature of the patients were compared with those of the normal controls (n=21). We found greater treatment response rate (defined as > or =50% reduction in headache index) in patients with biofeedback-assisted autogenic training than in monitoring group. The scores on the anxiety and depression scales in the patients receiving biofeedback-assisted autogenic training decreased after the biofeedback treatment. Moreover, the decrease in their anxiety levels was significantly related to the treatment outcome. This result suggests that the biofeedback-assisted autogenic training is effective for the treatment of migraine and its therapeutic effect is closely related to the improvement of the anxiety level.

2007-09-01

The recovery of patients undergoing total shoulder arthroplasty (TSA) can be adversely affected by a number of complications. Autologous platelet gel (APG), produced by activating platelet-rich plasma (PRP), has been shown to improve hemostasis and wound healing and reduce infections in some surgical procedures. Activated platelet-poor plasma (PPP) has also been used as a hemostatic agent. This study examines the effects of APG and PPP treatment on TSA patients postoperatively. After Institutional Review Board (IRB) approval, 40 patients undergoing TSA at our institution were prospectively enrolled in our study. They were randomized into either a control (n = 20) or study (n = 20) group, with the study group receiving APG and PPP treatment. Preoperative demographic data, pre- and postoperative laboratory data, pain scores, pain medication, complications, pre- and postoperative range of motion measurements, and postoperative lengths of stay were recorded for each group. The preoperative internal rotation index was significantly higher in the control group compared with treatment patients (4.64 +/- 4.46 vs. 1.88 +/- 2.44, p < .05). The percent hemoglobin retained postoperatively was higher in the treatment group at 24 (84.54 +/- 5.32 vs. 79.87 +/- 8.73) and 72 hours (87.46 +/- 16.03 vs. 76.70 vs. 5.96), but neither difference reached statistical significance. The treatment group had significantly lower pain scores (p = .007) and total fentanyl requirements (p < .05) compared with control patients. The internal rotation index improvement factor (postoperative internal rotation index/preoperative internal rotation index) was significantly higher in the treatment group vs. the control group (p < .05). Although it did not reach statistical significance, the treatment group was discharged almost 9 hours earlier than the control group (64.44 +/- 15.23 vs. 73.39 +/- 15.37). APG and PPP treatment decreased pain and provided a greater increase in internal rotation measurements postoperatively.

The main aim was to assess the effects of a spa treatment on the resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. A cost-effectiveness analysis (CEA) was also performed. A multicentre randomised controlled trial was carried out between 2008 and 2010 in the University Hospital of Auvergne and two private hospitals in Clermont-Ferrand, France. Eligible patients were women in complete breast cancer remission without contraindication for physical activities or cognitive disorders and a body mass index between 18.5 and 40 kg/m(2). The intervention group underwent spa treatment combined with consultation with dietician whereas the control underwent consultations with the dietician only. Of the 181 patients randomised, 92 and 89 were included in the intervention and the control groups, respectively. The CEA involved 90 patients, 42 from the intervention group and 48 from the control group. The main results showed a higher rate of resumption of occupational activities in the intervention group (p = 0.0025) and a positive effect of the intervention on the women's ability to perform occupational activities 12 months after the beginning of the study (p = 0.0014), and on their ability to perform family activities (p = 0.033). The stay in a thermal centre was cost-effective at 12 months. Spa treatment is a cost-effective strategy to improve resumption of occupational and non-occupational activities and the abilities of women in breast cancer remission. Copyright © 2014 Elsevier Ltd.

Hyperlipidemia is one of the major risk factors for atherosclerosis and ischemic heart disease. Chromium (Cr) mineral is playing a crucial role in glucose and lipid homeostasis. The aim of this study was to evaluate the protective effects of combined chromium picolinate (CrPic) and atorvastatin treatment against hyperlipidemia-induced cardiac injury. Seventy-five male albino rats were divided into five groups (15 rats each). Hyperlipidemia was induced by intraperitoneal injection of a single dose of Triton X-100 (300 mg/kg body weight (b.w) (group ІІ). Treatment of hyperlipidemic rats was induced by daily administration of CrPic at a dose of 200 μg/kg b.w/day (group ІІІ), atorvastatin at a dose of 10 mg/kg/day (group IV), and combined treatment with both (group V) by gavage for 7 days. At the end of experiment, serum and heart tissues were obtained. Hyperlipidemia was confirmed by histopathology of heart tissues, marked serum dyslipidemia, increased atherogenic indices, and values of ischemia-modified albumin. In addition to increased values of proprotein convertase subtilisin/kexin type 9, activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase enzyme and high relative expression levels of pentraxin-3 were observed. However, paraoxonase-1 activity was markedly decreased in the hyperlipidemic group. Significant improvement in all assessed parameters was observed in the rat group treated with both CrPic and atorvastatin. It can be concluded that combined CrPic and atorvastatin treatments had synergistic cardioprotective effects against hyperlipidemia which may be through modulating atherosclerosis as well as cardiac and aortic damage and/or activation of anti-inflammatory and anti-oxidant pathways, thus reversing endothelial dysfunction.

This study investigates outcome of scoliosis treatment for 11 children with Angelman syndrome (AS), with particular focus on activity, participation and the musculoskeletal factors that may affect these outcomes. Retrospective review of medical records, radiographs and questionnaires administered to caregivers of 11 children (8M:3F) with AS and scoliosis. Six underwent observational treatment during childhood and five underwent spinal fusion. The Activities Scale for Kids (ASKp) questionnaire was used to measure activity and participation. Questionnaire and radiographic data were recorded over a 2 year period. In the observational group, scoliosis increased from 31° to 46°. Mean ASKp decreased from 13.8 to 11.9 (p = 0.06). In the operative group, scoliosis decreased from 68° to 29°. Mean ASKp increased from 11.4 to 15.9 (p < 0.01). There was also a reduction in spinal-related pain and mean number of hospital admissions for chest infection. However, there was a 60% major complication rate. There was no difference in mobility, GMFCS level, feeding or communication in either group before or after treatment. In children with significant scoliosis and AS, spinal fusion was associated with a small improvement in activity and participation, reduction in pain and a decrease in frequency of severe chest infections. Non-operative treatment resulted in progression of scoliosis during childhood and decrease in activity.

Manual pressure release (MPR) is a popular treatment of trigger points. Yet, treatment response may be influenced by inconsistent application of pressure. Further, it may contribute to increased risk of work-related musculoskeletal disorders of the wrist and hand in therapists. Therefore, this study aimed at introducing a novel method to apply pressure using the algometer and to compare its effectiveness to MPR. Forty-five volunteers with active trigger points of the upper trapezius received algometer pressure release (APR), MPR, or sham ultrasound (US). Pain pressure threshold (PPT) and contralateral active and passive neck side-bending ranges were assessed at baseline and immediately after a single session. Results showed no significant differences in post-treatment PPT between the study groups (p > 0.05). The APR group showed a significant increase in passive side-bending range compared with the two other groups, whereas active range improved in the APR compared with the US group (p < 0.05). Our results show that using algometer to apply pressure release to upper trapezius trigger points is more effective compared with manual release and sham US. Copyright © 2016 Elsevier Ltd.

To observe the effects of modified Wuzi Yanzong Granule (WYG) on memory function and the activity of serum superoxide dismutase (SOD), malondialdehyde (MDA) levels, leukocyte mitochondrial DNA (mtDNA) deletion rate and beta-amyloid protein(1-28) (A beta(1-28)) in patients with mild cognitive impairment (MCI). Thirty-six patients with MCI were selected based on the internationally recognized Petersen's criteria, and equally and randomly assigned to two groups. The treated group was treated with WYG and the control group was treated with placebo for 3 months. In addition, 20 healthy subjects were included in the study as the normal control group. Changes of memory function, SOD activity, MDA content, leukocyte mtDNA deletion rate and A beta(1-28) content were observed before and after treatment. Compared with the normal control group, the memory quotient and SOD activity in patients with MCI decreased significantly (P < 0.01), while MDA, A beta(1-28) levels and the leukocyte mtDNA deletion rate increased significantly (P < 0.01). After treatment, levels of memory quotient and serum SOD activity increased while the serum MDA level, leukocyte mtDNA deletion rate and A beta(1-28) level decreased in the treated group compared with those before treatment (P<0.01, P<0.05). Meanwhile, leukocyte mtDNA deletion rate and A beta(1-28) content in the treated group were all lower than those in the control group (P<0.05). WYG could improve memory function in patients with MCI and the therapeutic mechanism is possibly related to the increased activity of anti-oxidase, the improved free radical metabolism and the alleviation of leukocyte mtDNA oxidation damage. WYG shows clinical significance in delaying the progression of MCI.

Abnormalities in motor activity represent a central feature in major depressive disorder. However, measurement issues are poorly understood, limiting the use of objective measurement of motor activity for diagnostics and treatment monitoring. To improve measurement issues, especially sensor placement, analytic strategies and diurnal effects, we assessed motor activity in depressed patients at the beginning (MD; n=27) and after anti-depressive treatment (MD-post; n=18) as well as in healthy controls (HC; n=16) using wrist- and chest-worn accelerometers. We performed multiple analyses regarding sensor placements, extracted features, diurnal variation, motion patterns and posture to clarify which parameters are most powerful in distinguishing patients from controls and monitoring treatment effects. Whereas most feature-placement combinations revealed significant differences between groups, acceleration (wrist) distinguished MD from HC (d=1.39) best. Frequency (vertical axis chest) additionally differentiated groups in a logistic regression model (R2=0.54). Accordingly, both amplitude (d=1.16) and frequency (d=1.04) showed alterations, indicating reduced and decelerated motor activity. Differences between MD and HC in gestures (d=0.97) and walking (d=1.53) were found by data analysis from the wrist sensor. Comparison of motor activity at the beginning and after MD-treatment largely confirms our findings. Sample size was small, but sufficient for the given effect sizes. Comparison of depressed in-patients with non-hospitalized controls might have limited motor activity differences between groups. Measurement of wrist-acceleration can be recommended as a basic technique to capture motor activity in depressed patients as it records whole body movement and gestures. Detailed analyses showed differences in amplitude and frequency denoting that depressed patients walked less and slower.

To conduct a kinematic comparison of occupational posture in orthodontists and dentists in their workplace. Observational study. Dentist surgeries and departments of orthodontics at university medical centres in Germany. A representative sample of 21 (10 female, 11 male) dentists (group G1) and 21 (13 female, 8 male) orthodontists (G2) with one male dropout in G2. The CUELA (computer-assisted acquisition and long-term analysis of musculoskeletal loads) system was used to analyse occupational posture. Parallel to the recording through the CUELA system, a software-supported analysis of the activities performed (I: treatment; II: office; III: other activities) was carried out. In line with ergonomic standards the measured body angles are categorised into neutral, moderate and awkward postures. Activities between the aforementioned groups are compared using the stratified van Elteren U test and the Wilcoxon-Mann-Whitney U test. All p values are subject to the Bonferroni-Holm correction. The level of significance is set at 5%. The percentage of time spent on activities in categories I-II-III was as follows: dentists 41%-23%-36% and orthodontists 28%-37%-35%. The posture analysis of both groups showed, for all percentiles (P5-95), angle values primarily in the neutral or moderate range. However, depending on the activity performed, between 5% and 25% of working hours were spent in unfavourable postures, especially in the head-and-neck area. Orthodontists have a greater tendency than dentists to perform treatment activities with the head and torso in unfavourable positions. The statistically significant differences between the two groups with regard to the duration and the relevance of the activities performed confirm this assumption for all three categories (p<0.01, p<0.05). Generally, both groups perform treatment activities in postures that are in the neutral or medium range; however, dentists had slightly more unfavourable postures during treatment for a greater share of their work day.

To evaluate the efficacy of chiropractic spinal manipulation, manual flexion/distraction, and hot pack application for the treatment of low back pain from osteoarthritis (OA) compared with moist heat alone. Two hundred fifty-two patients with low back pain secondary to OA were randomly assigned to either the treatment group (moist hot pack plus chiropractic care) or the moist heat group subjects, which attended 20 treatment sessions over several weeks. At sessions 1, 5, 10, 15, and 20, they rated pain using a visual analog pain scale, activities of daily living using the Oswestry Low Back Pain Questionnaire, and a range of motion (ROM) using the J-Tech Dual Digital Inclinometer (JTECH Medical Model no. AA036). Session I ratings indicated that the two groups were equivalent on all pain and flexion scores. The treatment group reported greater and more rapid pain reduction and greater and more rapid ROM improvement than the moist heat group. The treatment group also had greater improvements than the moist heat group in daily living activities in 4 of the 9 areas measured. Chiropractic care combined with heat is more effective than heat alone for treating OA-based lower back pain. Pain reduction occurs more rapidly and to a greater degree, and ROM increases more rapidly and to a greater degree.

To assess the long-term efficacy of the most widely used anti-tumor necrosis factor alpha (TNFα) agents for treatment of HLA-B27-positive ankylosing spondylitis (AS)-related uveitis. Retrospective cohort study. The medical records of 143 patients with HLA-B27-positive AS who visited Seoul St. Mary's Hospital and were taking an anti-TNFα agent for at least 1 year were studied. Subjects were divided into 3 groups according to anti-TNFα treatment: Group 1 (infliximab, 66), Group 2 (adalimumab, 45), and Group 3 (etanercept, 32). Mean age was 41.0 ± 13.0 years, and 97 patients (67.8%) were male. Mean follow-up period was 70.6 ± 37.9 months. In cases of active ocular inflammation at the onset of anti-TNFα treatment, patients showed improved activity of uveitis after 24.0 ± 15.0 days (Group 1), 17.9 ± 6.0 days (Group 2), and 25.9 ± 18.0 days (Group 3). After the anti-TNFα treatment, 71 of 94 patients (32 [76.2%] in Group 1, 26 [78.8%] in Group 2, and 13 [68.4%] in Group 3) remained without uveitis relapse. A reduction in the number of systemic medications was achieved in 129 patients (90.2%). Twenty-eight cases of minor side effects were observed, and 4 cases were tuberculosis leading to discontinuation of anti-TNFα treatment. Infliximab, adalimumab, and etanercept were effective for treating and reducing the number of uveitis relapses in HLA-B27-positive AS. However, the risk of serious infections was noted, so ophthalmologists should consider the possibility that prolonged use of biologic agents may result in systemic side effects.

The incidence of lung cancer is increasing with longer life expectancy. Refusal of active treatment for cancer is prone to cause patients to experience more severe symptoms and shorten survival. The purpose of this study was to define the factors related to refusal or abandonment of active therapy in lung cancer. We retrospectively reviewed the data of 617 patients from medical records from 2010 to 2014. Two groups were formed: 149 patients who refused anti-cancer treatment and allowed only palliative care were classified into the non-treatment group, while the remaining 468 who received anti-cancer treatment were classified into the treatment group. The groups differed significantly in age, employment, relationship status, number of offspring, educational status, body mass index, presence of chest and systemic symptoms, Charlson Comorbidity Index, Eastern Cooperative Oncology Group score, and tumor node metastasis stage ( P < 0.05). In logistic regression analysis, age (odds ratio [OR] 1.10, 95% confidence interval [CI] 1.07-1.13), educational status lower than high school (OR 1.95, 95% CI 1.2-3.2), no history of surgery (OR 2.29, 95% CI 1.4-3.7), body mass index < 18.5 (OR 2.49, 95% CI 1.3-4.7), and a high Eastern Cooperative Oncology Group score of 3 or 4 (OR 5.02, 95% CI 2.3-10.8) were significant factors for refusal of cancer treatment. Individual factors, such as old age, low educational status, low weight, and poor performance status can influence refusal of cancer treatment in patients with lung cancer, and should be considered prior to consultation with patients. © 2017 The Authors.

Heart Rate Variability (HRV) indicates how heart rate changes in response to inner and external stimuli. HRV is linked to health status and it is an indirect marker of the autonomic nervous system (ANS) function. To investigate the influence of osteopathic manipulative treatment (OMT) on cardiac autonomic modulation in healthy subjects, compared with sham therapy and control group. Sixty-six healthy subjects, both male and female, were included in the present 3-armed randomized placebo controlled within subject cross-over single blinded study. Participants were asymptomatic adults (26.7 ± 8.4 y, 51% male, BMI 18.5 ± 4.8), both smokers and non-smokers and not on medications. At enrollment subjects were randomized in three groups: A, B, C. Standardized structural evaluation followed by a patient need-based osteopathic treatment was performed in the first session of group A and in the second session of group B. Standardized evaluation followed by a protocoled sham treatment was provided in the second session of group A and in the first session of group B. No intervention was performed in the two sessions of group C, acting as a time-control. The trial was registered on clinicaltrials.gov identifier: NCT01908920. HRV was calculated from electrocardiography before, during and after the intervention, for a total amount time of 25 min and considering frequency domain as well as linear and non-linear methods as outcome measures. OMT engendered a statistically significant increase of parasympathetic activity, as shown by High Frequency power (p < 0.001), expressed in normalized and absolute unit, and possibly decrease of sympathetic activity, as revealed by Low Frequency power (p < 0.01); results also showed a reduction of Low Frequency/High Frequency ratio (p < 0.001) and Detrended fluctuation scaling exponent (p < 0.05). Findings suggested that OMT can influence ANS activity increasing parasympathetic function and decreasing sympathetic activity, compared to sham therapy and control group.

Around 25% of patients with systemic lupus erythematosus (SLE) could be refractory to conventional therapies. P-glycoprotein expression on cell surface has been implied on drug resistance, however, to date, it is unknown if P-gp serum levels are associated with SLE disease activity. Evaluate the association of serum P-gp levels and SLE with disease activity despite treatment. A cross-sectional study was conducted on 93 female SLE patients, all receiving glucocorticoids at stable doses for the previous 6 months before to baseline. SLE patients were classified into two groups: (a) patients with active disease [SLE disease activity index (SLEDAI) ≥ 3] despite treatment, and (b) patients with inactive disease (SLEDAI < 3) after treatment. Forty-three healthy females comprised the control group. Serum P-gp, anti-DNA, and both anti-nucleosome antibody levels were measured using ELISA. Active-SLE patients despite treatment had higher P-gp levels compared with inactive-SLE after treatment (78.02 ng/mL ± 114.11 vs. 33.75 ng/mL ± 41.11; p = 0.018) or versus reference group subjects (30.56 ng/mL ± 28.92; p = 0.011). P-gp levels correlated with the scores of SLEDAI (r = 0.26; p = 0.01), Mexican-SLEDAI (MEX-SLEDAI) (r = 0.32; p = 0.002), SLICC/ACR damage index (r = 0.47; p < 0.001), and with prednisone doses (r = 0.33; p = 0.001). In the multivariate model, the high P-gp levels were associated with SLICC/ACR score (p = 0.001), and SLEDAI score (p = 0.014). Our findings support a relationship between serum P-gp levels and SLE with disease activity despite treatment, but it requires further validation in longitudinal studies.

Many similarities exist between pyogenic flexor tenosynovitis and other closed-space infections such as septic arthritis. Previous studies have demonstrated that corticosteroids in conjunction with antibiotics considerably improve treatment outcomes in patients with septic arthritis. Using a chicken model, we investigated whether or not corticosteroids in combination with antibiotics and/or surgical drainage could minimize the loss of range of motion typically associated with pyogenic flexor tenosynovitis. We inoculated the flexor tendon sheath of the right long toe of broiler chickens with Staphylococcus aureus (American Type Culture Collection 29523 NA) (6 × 10(9) colony-forming units/mL) and twenty-four hours later administered one of six treatments to groups of fourteen or fifteen chickens. Treatment combinations included systemic or intrasynovial antibiotics, surgical drainage with catheter irrigation or no surgical drainage, and local corticosteroid injections or no corticosteroid injections. Measurements of active digital flexion at the proximal and middle interphalangeal joints were performed before inoculation and treatment and at seven, fourteen, and twenty-eight days after treatment. Flexion measurements were compared between groups as well as with similar measurements in the contralateral, uninfected, control long toe. At twenty-eight days, two of three groups treated with locally administered corticosteroids and the group treated with intrasynovial antibiotics alone (without surgery) regained significantly more active flexion in comparison with chickens treated with systemic antibiotics and surgical drainage (the current standard of care). Pooled data revealed that the corticosteroid-treated groups regained significantly more active flexion at all post-treatment time points. Our data support the hypothesis that adding locally administered corticosteroids to the treatment regimen for pyogenic flexor tenosynovitis in a chicken model can significantly decrease loss of motion resulting from the infection. Furthermore, locally administered antibiotics may be effective for the treatment of pyogenic flexor tenosynovitis.

The purpose of this study was to evaluate the efficacy of non-invasive methods of treatment for active incipent occlusal caries. Anamnesis, professional prophylaxis, and visual inspection were used to classify 250 Brazilian pre-school-children. First permanent decayed molars (n=98) from thirty-one subjects (6 years+ 6 months) were selected and divided into three groups. Group 1: fissure sealants with resin-modified glass ionomer - Vitremer (n=29); Group 2: fluoride varnish -Duraphat (n=36) and control group: tooth brushing and 0.2 percent NaF weekly mouthwashes (n=33). Four clinical evaluations were carried out over three, six, nine, and twelve months. Caries activity and progression were observed through clinical and radiographic evaluation. The results were analyzed by Fisher=s Exact test. After twelve months, the results showed 100 percent of arrestment of caries activity for Group 1, 83.3 percent for group 2, and 72.7 percent for control group. At the same time, the results showed 0 percent of caries progression for group 1, 5.5 percent for Group 2, and 6.1 percent for control group. Group 1 showed a better inactivation property than the other groups (p<0.05). There were no statistically significant differences in caries progression among these groups (p>0.05). It was concluded that this non-invasive methods were able to arrest the progression of occlusal caries, but fissure sealant showed better results in controlling caries activity.

To assess the efficacy of enzyme potentiated desensitisation in the treatment of severe summer hay fever poorly controlled by pharmacotherapy. Double blind randomised placebo controlled parallel group study. Hospital in Hampshire. 183 participants aged between 18 and 64 with a history of severe summer hay fever for at least two years; all were skin prick test positive to timothy grass pollen. 90 randomised to active treatment; 93 randomised to placebo. Active treatment: two injections of enzyme potentiated desensitisation, given between eight and 11 weeks apart, each comprising 200 Fishman units of beta glucuronidase, 50 pg 1,3-cyclohexanediol, 50 ng protamine sulphate, and a mixed inhaled allergen extract (pollen mixes for trees, grasses, and weeds; allergenic fungal spores; cat and dog danders; dust and storage mites) in a total volume of 0.05 ml of buffered saline. Placebo: two injections of 0.05 ml buffered saline solution. Proportion of problem-free days; global rhinoconjunctivitis quality of life scores assessed weekly during pollen season. The active treatment group and the placebo group did not differ in the proportion of problem-free days, quality of life scores, symptom severity scores, change in quantitative skin prick provocation threshold, or change in conjunctival provocation threshold. No clinically significant adverse reactions occurred. Enzyme potentiated desensitisation showed no treatment effect in this study.

Most midshaft clavicle fractures affect the economically active population, which is negatively impacted by transient limb impairment during the treatment. There is still debate about the advantages and disadvantages of surgical treatment for these fractures. In this prospective randomized controlled trial, 117 patients were allocated to 1 of 2 groups: nonsurgical treatment with a figure-of-eight harness or surgical treatment with anteroinferior plate osteosynthesis. The primary outcome was upper-limb limitation measured with the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire at 6 months. Other outcomes included pain, radiographic findings, satisfaction with the cosmetic result, complications, and time to return to previous work and activities. Participants were assessed at 6 weeks, 6 months, and 1 year after the intervention. No difference between the 2 groups was detected in the DASH score at any time point (p = 0.398, 0.403, and 0.877 at 6 weeks, 6 months, and 1 year, respectively), pain levels measured with a visual analogue scale (VAS), time to return to previous activities, or dissatisfaction with the cosmetic result. Seven patients (14.9%) developed nonunion after nonsurgical treatment, a nonunion rate that was significantly higher than that in the surgical group, in which all fractures had healed (p = 0.004). The patients in the nonsurgical group had radiographic evidence of greater clavicle shortening (p < 0.001) and more of the patients in that group answered "yes" when asked if their clavicle felt short (p < 0.001) and if they felt bone prominence (p < 0.001). More patients answered "yes" when asked if they felt paresthesia in the surgical group (7; 13.7%) than in the nonsurgical group (1; 2.1%) (p = 0.036). This study did not demonstrate a difference in limb function between patients who underwent surgical treatment and those nonsurgically treated for a dislocated midshaft clavicle fracture. Meanwhile, surgical treatment decreased the likelihood of nonunion. Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

This study reports the clinical emergency treatment of 68 critical patients with severe organophosphorus poisoning, and analyzes the prognosis after rescue.The general data of 68 patients with severe organophosphorus poisoning treated in our hospital were retrospectively analyzed. These patients were divided into 2 groups: treatment group, and control group. Patients in the control group received routine emergency treatment, while patients in the treatment group additionally received hemoperfusion plus hemodialysis on the basis of routine emergency treatment. The curative effects in these 2 groups and the prognosis after rescue were compared.Compared with the control group, atropinization time, recovery time of cholinesterase activity, recovery time of consciousness, extubation time, and length of hospital stay were shorter (P < .05); the total usage of atropine was significantly lower (P < .05); Glasgow Coma Score was significantly higher (P < .05); acute physiology and chronic health score (APACHE II) was significantly lower (P < .05); and mortality and poisoning rebound rate was significantly lower (P < .05) in the treatment group.Hemoperfusion and hemodialysis on the basis of routine emergency treatment for critical patients with organophosphorus poisoning can improve rescue outcomes and improve the prognosis of patients, which should be popularized.

Introduction: The demand for esthetic dental treatments is increasing in recent years mainly due to improved oral hygiene and better maintenance of oral health and teeth in older individuals. Bleaching of discolored anterior teeth is the most popular among esthetic dental treatments. Even individuals with sound teeth and adequate esthetics seek to have whiter teeth in the anterior region. The aim of this study was to evaluate tooth color changes following conventional in-office bleaching techniques compared to light-activated methods using different light sources. Methods: Seventy sound anterior teeth (devoided of caries and/or fracture), extracted for periodontal and orthodontic reasons were selected and allocated to 7 groups: (A) control, (B) conventional bleaching (C) LED-activated bleaching, (D) KTP laser-activated bleaching, (E) diode laser-activated bleaching, (F) Nd:YAG laser-activated bleaching and (G) CO2 laser-activated bleaching. Colorimetric evaluation was carried out before and after treatment using a spectrophotoradiometer. Data were analyzed by one- and two-way analysis of variance (ANOVA) as well as multiple comparison methods. Results: The results showed that all bleaching procedures were effective in reducing the yellowness index. However, the KTP laser-activated bleaching was significantly more effective than the other techniques in 95% confidence level. It was also seen that CO2 laser activated method has outperformed groups E, F and G and the conventional bleaching without light activation was not effective at all and represented similar results with the control group. Furthermore, the groups E and G had almost the same results in decreasing the yellowness index. Conclusion: The results showed that all bleaching techniques were effective however, the KTP laser-activated bleaching was significantly more efficient, closely followed by the CO2 laser-activated bleaching technique.

BACKGROUND—Peptic ulcers with active bleeding or a non-bleeding visible vessel require aggressive endoscopic treatment. 
AIMS—To determine whether endoscopic adrenaline injection alone or contact probe therapy following injection is a suitable treatment for peptic ulcer bleeding. 
METHODS—A total of 96 patients with active bleeding or non-bleeding visible vessels received adrenaline alone, bipolar electrocoagulation alone, or combined treatment (n=32 in each group). 
RESULTS—Initial haemostasis was not achieved in one patient in the adrenaline group, two in the gold probe group, and two in the injection gold probe group (p>0.1). Rebleeding episodes were fewer in the injection gold probe group (2/30, 6.7%) than in the gold probe group (9/30, 30%, p=0.04) and in the adrenaline group (11/31, 35.5%, p=0.01). Treatment failure (other therapy required) was rarer in the injection gold probe group (4/32, 12.5%) than in the adrenaline group (12/32, 37.5%, p=0.04). The volume of blood transfused after entry of the study was less in the injection gold probe group (mean 491 ml) than in the adrenaline group (1548ml, p<0.0001) and the gold probe group (1105 ml, p<0.01). Duration of hospital stay, numbers of patients requiring urgent surgery, and death rate were not statistically different among the three groups. 
CONCLUSIONS—For patients with peptic ulcer bleeding, combined adrenaline injection and gold probe treatment offers an advantage in preventing rebleeding and decreasing the need for blood transfusion.

To investigate the efficacy of mirror therapy in reducing pain and disability in patients with distal radial fractures. Pilot randomized controlled study. Twenty-two patients with closed distal radial fracture. Patients were randomly assigned to experimental (= 11) or control (= 11) groups. Researchers were blinded to group allocation. Both groups received conventional physiotherapy. In addition, the experimental group had 15 sessions of mirror therapy (a daily session, 30 min). The control group received the same amount of conventional occupational therapy. Assessment was made from baseline to post-treatment. Pain was measured on a visual analogue scale (VAS). Active wrist extension and Quick-DASH (Disabilities of Arm, Shoulder and Hand) were used to assess functional recovery. Pain, disability, and range of motion improved for both groups after intervention. No significant post-treatment differences were found between groups in Quick-DASH (= 0.409), active wrist extension (= 0.191) and VAS scores (= 0.807). There was no significant difference in active wrist extension between groups. Mirror therapy was not superior to conventional occupational therapy in reducing pain and disability.

Brucellosis is associated with inflammation and the oxidative stress response. Heme oxygenase-1 (HO-1) is a cytoprotective stress-responsive enzyme that has anti-inflammatory and anti-oxidant effects. Nevertheless, the role of HO-1 in human brucellosis has not yet been studied. The aim of this study was to examine the plasma levels of HO-1 in patients with brucellosis and to evaluate the ability of plasma HO-1 levels as an auxiliary diagnosis, a severity predictor, and a monitor for brucellosis treatments. A total of 75 patients with brucellosis were divided into the acute, subacute, chronic active, and chronic stable groups. An additional 20 volunteers were included as the healthy control group. The plasma HO-1 levels and other laboratory parameters were measured in all groups. Furthermore, the plasma levels of HO-1 in the acute group were compared before and after treatment. The plasma HO-1 levels were considerably increased in the acute (4.97 ± 3.55), subacute (4.98 ± 3.23), and chronic active groups (4.43 ± 3.00) with brucellosis compared to the healthy control group (1.03 ± 0.63) (p < 0.01). In the acute group, the plasma HO-1 levels in the post-treatment group (2.33 ± 2.39) were significantly reduced compared to the pre-treatment group (4.97 ± 3.55) (p < 0.01). On the other hand, the plasma HO-1 levels were higher in the chronic active group (4.43 ± 3.00) than the chronic stable group (2.74 ± 2.23) (p < 0.05). However, the plasma HO-1 levels in the chronic stable group (2.74 ± 2.23) remained higher than the levels in the healthy control group (1.03 ± 0.63) (p < 0.05). The HO-1 levels were positively correlated with the C-reactive protein (CRP) levels in patients with brucellosis (r = 0.707, p < 0.01). The plasma HO-1 levels can reflect patients' brucellosis status and may be used as a supplementary plasma marker for diagnosing brucellosis and monitoring its treatment.

Sonchus arvesis is traditionally reported in various human ailments including hepatotoxicity in Pakistan. Presently we designed to assess the protective effects of methanolic extract of Sonchus arvesis against carbon tetrachloride induced genotoxicity and DNA oxidative damages in hepatic tissues of experimental rats. 36 male Sprague-Dawley rats were randomly divided into 6 groups to evaluate the hepatoprotective effects of Sonchus arvensis against CCl4 induced genotoxicity, DNA damages and antioxidant depletion. Rats of normal control group were given free access of food and water add labitum. Group II rats received 3 ml/kg of CCl4 (30% in olive oil v/v) via the intraperitoneal route twice a week for four weeks. Group III and IV received 1 ml of 100 mg/kg b.w. and 200 mg/kg b.w. SME via gavage after 48 h of CCl4 treatment whereas group V was given 1 ml of silymarin (100 mg/kg b.w.) after 48 h of CCl4 treatment. Group VI only received 200 mg/kg b.w. SME. Protective effects of SME were checked by measuring serum markers, activities of antioxidant enzymes, genotoxicity and DNA dmages. Results of the present study showed that treatment of SME reversed the activities of serum marker enzymes and cholesterol profile as depleted with CCl4 treatment. Activities of endogenous antioxidant enzymes of liver tissue homogenate; catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSHpx), glutathione-S-transferase (GST) and glutathione reductase (GSR) were reduced with administration of CCl4, which were returned to the control level with SME treatment. CCl4-induced hepatic cirrhosis decreased hepatic glutathione (GSH) and increased lipid peroxidative products (TBARS), were normalized by treatment with SME. Moreover, administration of CCl4 caused genotoxicity and DNA fragmentation which were significantly restored towards the normal level with SME. These results reveal that treatment of SME may be useful in the prevention of hepatic stress.

Traumatic brain injury (TBI) leads to important and deleterious inflammation, as evidenced by edema, cytokine production, induction of nitric oxide synthase, and leukocyte infiltration. After TBI, the activation of cerebral vascular endothelial cells plays a crucial role in the pathogenesis of inflammation. In this study, we hypothesized that the activation of cerebral vascular endothelial cells plays a crucial role in the pathogenesis of inflammation and outcome after TBI. It may represent a key cellular target for statin therapy. In our study, cortical contusions were induced, and the effect of continuous treatment of simvastatin on behavior and inflammation in adult rats following experimental TBI was evaluated. The treatment group received 15 mg/kg of simvastatin daily for 3 days. Neurological function was assessed with the grip test. The results showed that the non-treatment control group had a significantly greater increase in ICAM-1 expression from pre-injury to the post-injury 72 h time point as compared to the expression in treatment group. The treatment group had better neurological function as evidenced in a grip test performed from baseline to 72 h. The analysis of a western blot test and pathology also demonstrated reduced ICAM-1 expression and a smaller area of damage and tissue loss. Our findings suggest that simvastatin could attenuate the activation of cerebral vascular endothelial inflammatory response and decrease the loss of neurological function and brain tissue.

The widespread and sustained use of mobile and cordless phones causes unprecedented increase of radiofrequency radiation (RFR). The aim of this experimental study was to investigate the effect of 900 MHz Global System for Mobile Communications (GSM)-modulated RFR (average whole body Specific Absorption Rate (SAR) of 0.4 W/kg, 10 or 20 min daily for consecutive 7 days) to the liver tissue of guinea pigs and the protective effects of antioxidant treatments. Adult male guinea pigs were randomly divided into nine groups as: Group I (sham/saline), Group II (sham/EGCG), Group III (sham/NAC), Group IV (10-min RF-exposure/saline), Group V (20-min RF-exposure/saline), Group VI (10-min RF-exposure/EGCG), Group VII (20-min RF-exposure/EGCG), Group VIII (10-min RF-exposure/NAC), and Group IX (20-min RF-exposure/NAC). Protein oxidation (PCO), advanced oxidation protein products (AOPP) and antioxidant enzyme activities of superoxide dismutase (SOD) were evaluated after the exposure and the treatments with N-acetylcysteine (NAC) and (-)-epigallocatechin-3-gallate (EGCG). Significant decreases in the activities of SOD were observed in the liver of guinea pigs after RFR exposure. Protein damage did not change due to RFR exposure. On the other hand, only NAC treatment induced increased PCO levels, whereas EGCG treatment alone elevated the level of AOPP. Due to antioxidants having pro-oxidant behavior, the well decided doses and treatment timetables of NAC and ECGC are needed.

To investigate the clinical effect of hemoperfusion combined with hemodialysis in the treatment of severe organophosphate pesticide poisoning. Ninety-eight patients with severe organophosphate pesticide poisoning who were admitted to the emergency department of our hospital from March 2005 to September 2013 were equally divided into control group and observation group according to treatment methods. The control group was given conventional emergency treatment, while the observation group was given hemoperfusion combined with hemodialysis and the conventional emergency treatment. The clinical outcomes and complications of two groups were compared. In the control group, 35 patients were cured and 14 patients died, so the cure rate was 71.4%. In the treatment group, 46 patients were cured and 3 patients died, so the cure rate was 93.9%. The treatment group had a significantly higher cure rate than the control group (χ² = 8.611, P < 0.05). And the treatment group had significantly shorter duration of coma (P < 0.01), mean length of hospital stay (P < 0.01), and time to recovery of cholinesterase activity (P < 0.01) and a significantly reduced dose of atropine than the control group (P < 0.01). The control group had significantly more cases of urinary retention than the treatment group (18 vs. 6, χ² = 4.991, P < 0.05). And the control group had more cases of intermediate syndrome, respiratory failure, delayed neurological damage, and rebound than the treatment group. Hemoperfusion combined hemodialysis has a good clinical effect and causes fewer complications in treating severe organophosphate pesticide poisoning, so it is worthy of clinical promotion.

Eighty hand spasm patients of post-stroke within one year after stroke were randomly divided into an observation group and a control group, 40 cases in each one. In the two groups, rehabilitation was adopted for eight weeks,once a day,40 min one time. In the observation group, based on the above treatment and according to muscle fascia trigger point, 2~3 points in both the internal and external sides of forearm were treated with floating-needle. The positive or passive flexion and extension of wrist and knuckle till the relief of spasm hand was combined. The floating-needle therapy was given for eight weeks, on the first three days once a day and later once every other day. Modified Ashworth Scale(MAS), activity of daily life(ADL, Barthel index) scores and Fugl-Meyer(FMA) scores were used to assess the spasm hand degree,activity of daily life and hand motion function before and after 7-day, 14-day and 8-week treatment. After 7-day, 14-day and 8-week treatment, MAS scores were apparently lower than those before treatment in the two groups(all P<0. 05), and Barthel scores and FMA scores were obviously higher than those before-treatment(all P<0. 05). After 14-day and 8-week treatment, FMA scores in the observation group were markedly higher than those in the control group(both P<0. 05). Floating-needle therapy combined with rehabilitation training and simple rehabilitation training could both improve hand spasm degree, hand function and activity of daily life of post-stroke patients, but floating-needle therapy combined with rehabilitation training is superior to simple rehabilitation training for the improvement of hand function.

This study compared the effectiveness of two group treatments, behavioral activation (BA) and cognitive therapy (CT), in reducing subsyndromal anxiety and depressive symptoms in a sample of Iranian university students. Twenty-seven Iranian university students who scored 18 or higher on the depression subscale and 16 or higher on the anxiety subscale of the Depression, Anxiety, and Stress Scale (DASS-42) were randomly assigned into treatment groups. One group received 8 sessions of BA (n = 14), and the other received 8 sessions of group CT (n = 13). Analysis of covariance revealed that the BA group had a significantly greater reduction in depressive symptoms than the CT group. However, there were no significant differences between the two groups in the levels of anxiety, stress symptoms or functional impairment after treatment. This study found evidence for the effectiveness of BA in reducing anxiety, depressive and stress symptoms and functional impairment compared to CT. BA was more effective than CT in improving depressive symptoms and was as effective as CT in decreasing anxiety, stress and functional impairment. BA is also a cost-effective intervention, particularly in group formats.

We investigated the effects of Hericium erinaceus (HEE) on alloxan induced diabetic neuropathic pain in laboratory rats. Alloxan induced diabetic rats were administered orally HEE. After 6 weeks of treatments, treatment with HEE 40 mg/kg in diabetic animals showed significant increase in pain threshold and paw withdrawal threshold and significant decrease in serum glucose and urine glucose. We also observed a significant increase in lactate dehydrogenase (LDH), Lipid peroxidation (LPO), glutathione peroxidase (GPx) activity, glutathione reductase (GR) activity, catalase (CAT) activity, Na+K+ATPase activity, and glutathione S transferase (GST) activity along with significant decreased levels of glutathione (GSH) content in diabetic rats. The total antioxidant status (TAOS) in the HEE-treated groups was significantly lower than that in the alloxan-treated group. HEE can offer pain relief in diabetic neuropathic pain. The improvement in diabetic state after HEE treatment along with the antioxidant activity could be the probable way by which it had alleviated diabetic neuropathy. PMID:25960754

Cohesive taping is commonly used for the prevention or treatment of ankle sprain injuries. Short-leg cast immobilization or splinting is another treatment option in such cases. To determine the clinical efficacy and antiedema effects of cohesive taping and short-leg cast immobilization in acute low-type ankle sprains of physically active patients, we performed a preliminary clinical study to assess objective evidence for edema and functional patient American Orthopaedic Foot and Ankle Society (AOFAS) scores with these alternative treatments. Fifty-nine physically active patients were included: 32 in the taping group and 27 in the short-leg cast group within a year. If a sprain was moderate (grade II) or mild (grade I), we used functional taping or short-leg cast immobilization for 10 days. We evaluated the edema and the functional scores of the injured ankle using the AOFAS Clinical Rating System on days 1, 10, and 100. In each group, edema significantly decreased and AOFAS scores increased indicating that both treatment methods were effective. With the numbers available, no statistically significant difference could be detected. Each treatment method was effective in decreasing the edema and increasing the functional scores of the ankle. At the beginning of treatment, not only the level of edema but also the initial functional scores of the ankle and examinations are important in making decisions regarding the optimal treatment option.

Group cognitive behavioural therapy and group recreational activity for adults with autism spectrum disorders: A preliminary randomized controlled trial

Although adults with autism spectrum disorder are an increasingly identified patient population, few treatment options are available. This preliminary randomized controlled open trial with a parallel design developed two group interventions for adults with autism spectrum disorders and intelligence within the normal range: cognitive behavioural therapy and recreational activity. Both interventions comprised 36 weekly 3-h sessions led by two therapists in groups of 6–8 patients. A total of 68 psychiatric patients with autism spectrum disorders participated in the study. Outcome measures were Quality of Life Inventory, Sense of Coherence Scale, Rosenberg Self-Esteem Scale and an exploratory analysis on measures of psychiatric health. Participants in both treatment conditions reported an increased quality of life at post-treatment (d = 0.39, p < 0.001), with no difference between interventions. No amelioration of psychiatric symptoms was observed. The dropout rate was lower with cognitive behavioural therapy than with recreational activity, and participants in cognitive behavioural therapy rated themselves as more generally improved, as well as more improved regarding expression of needs and understanding of difficulties. Both interventions appear to be promising treatment options for adults with autism spectrum disorder. The interventions’ similar efficacy may be due to the common elements, structure and group setting. Cognitive behavioural therapy may be additionally beneficial in terms of increasing specific skills and minimizing dropout. PMID:24089423

Adult male hamsters were maintained under 14 hours of light per day and randomly assigned to groups that received daily afternoon melatonin (25 micrograms) or vehicle injections. Animals from both groups were killed following 4, 8, and 12 weeks of treatment. By 12 weeks, the melatonin-treated hamsters had significant reductions in the weights of the testes and seminal vesicles, serum testosterone levels, and activities did not differ between groups. In a second experiment, hamsters were hypothalamic-preoptic area (HPOA) aromatase activities. Hypothalamic-preoptic area 5 alpha-reductase activities did not differ between groups. In a second experiment, hamsters were again treated with melatonin or vehicle for 12 weeks prior to being killed. After 10 weeks of treatment, groups of melatonin-treated animals received subcutaneous silastic capsules (5, 10, or 20 mm) filled with testosterone. Animals in two other groups were given blank implants or no implants at all. Two weeks later, at autopsy, reproductive organ weights, serum testosterone levels, and HPOA aromatase activities were significantly suppressed by melatonin administration. 5 alpha-Reductase activity in the HPOA was not affected. Hamsters that had been given the 10- and 20-mm testosterone implants exhibited normal seminal vesicle weights and HPOA aromatase activities. These results suggest that melatonin-induced reduction of HPOA aromatase activity is mediated by decreased circulating levels of testosterone.

Polystyrene-based activated carbon spheres (PACS) were modified with either air, HNO 3, (NH 4) 2S 2O 8, H 2O 2 or H 2 to improve their adsorption properties of dibenzothiophene (DBT). The texture and surface chemistry of PACS were characterized by N 2 adsorption, scanning electron microscopy (SEM), temperature-programmed desorption (TPD), X-ray photoelectron spectroscopy (XPS), acid-base titration and elemental analysis. The results showed that HNO 3 and (NH 4) 2S 2O 8 treatments introduced large amount of acidic groups such as carboxylic, lactones and anhydride groups, while air and H 2O 2 had relatively mild effects and introduced a small quantity of phenol, carbonyl and ether groups. In the HNO 3 treatment, the acidic groups might be fixed on the internal and external surface of PACS, which may act as active sites of adsorption, resulting in increase of the adsorption amount by 45%. Whereas H 2O 2 and (NH 4) 2S 2O 8 treatments might fix more oxygen-containing groups on the external surface, which may hinder DBT molecule enter into micropores, leading to rather lower adsorption capacity with the extent of oxidation. So, the concentration, distribution and types of the acidic functional groups are responsible for the removal of DBT.

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.

Active-comparator design and new-user design in observational studies

SUMMARY Over the past decade, an increasing number of observational studies have examined the effectiveness or safety of rheumatoid arthritis treatments. However, unlike randomized controlled trials (RCTs), observational studies of drug effects face methodological challenges including confounding by indication. Two design principles - active comparator design and new user design can help mitigate such challenges in observational studies. To improve validity of study findings, observational studies should be designed in such a way that makes them more closely approximate RCTs. The active comparator design compares the drug of interest to another commonly used agent for the same indication, rather than a ‘non-user’ group. This principle helps select treatment groups similar in treatment indications (both measured and unmeasured characteristics). The new user design includes a cohort of patients from the time of treatment initiation, so that it can assess patients’ pretreatment characteristics and capture all events occurring anytime during follow-up.

Multidisciplinary treatments have shown to be effective for fibromyalgia. We report detailed functional outcomes of patients with fibromyalgia who attended a 3-month Multidisciplinary treatment program. The hypothesis was that patients would have increased functional status, physical activity level, and exercise regularity after attending this program. We performed a retrospective analysis of a randomized, simple blinded clinical trial. The inclusion criteria consisted of female sex, a diagnosis of fibromyalgia, age 18-60  and 3-8 years of schooling. Measures from the Fibromyalgia Impact Questionnaire (FIQ) and the COOP/WONCA Functional Health Assessment Charts (WONCA) were obtained before and at the end of the treatment and at 3-, 6-, and 12-month follow-ups. Patients recorded their number of steps per day with pedometers. They performed the six-minute walk test (6 MW) before and after treatment. In total, 155 women participated in the study. Their median (interquartile interval) FIQ score was 68.0 (53.0-77.0) at the beginning of the treatment, and the difference between the Multidisciplinary and Control groups was statistically and clinically significant in all of the measures (except the 6-month follow-up). The WONCA charts showed significant clinical improvements in the Multidisciplinary group, with physical fitness in the normal range across almost all values. In that group, steps/day showed more regularity, and the 6 MW results showed improvement of -33.00 (-59.8 to -8.25) m, and the differences from the Control group were statistically significant. The patients who underwent the Multidisciplinary treatment had improved functional status, physical activity level, and exercise regularity. The functional improvements were maintained 1 year after treatment completion.

Most patients with Crohn's disease need an intestinal resection, but a majority will subsequently experience disease recurrence and require further surgery. This study aimed to identify the optimal strategy to prevent postoperative disease recurrence. In this randomised trial, consecutive patients from 17 centres in Australia and New Zealand undergoing intestinal resection of all macroscopic Crohn's disease, with an endoscopically accessible anastomosis, received 3 months of metronidazole therapy. Patients at high risk of recurrence also received a thiopurine, or adalimumab if they were intolerant to thiopurines. Patients were randomly assigned to parallel groups: colonoscopy at 6 months (active care) or no colonoscopy (standard care). We used computer-generated block randomisation to allocate patients in each centre to active or standard care in a 2:1 ratio. For endoscopic recurrence (Rutgeerts score ≥i2) at 6 months, patients stepped-up to thiopurine, fortnightly adalimumab with thiopurine, or weekly adalimumab. The primary endpoint was endoscopic recurrence at 18 months. Patients and treating physicians were aware of the patient's study group and treatment, but central reading of the endoscopic findings was undertaken blind to the study group and treatment. Analysis included all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT00989560. Between Oct 13, 2009, and Sept 28, 2011, 174 (83% high risk across both active and standard care groups) patients were enrolled and received at least one dose of study drug. Of 122 patients in the active care group, 47 (39%) stepped-up treatment. At 18 months, endoscopic recurrence occurred in 60 (49%) patients in the active care group and 35 (67%) patients in the standard care group (p=0.03). Complete mucosal normality was maintained in 27 (22%) of 122 patients in the active care group versus four (8%) in the standard care group (p=0.03). In the active care arm, of those with 6 months recurrence who stepped up treatment, 18 (38%) of 47 patients were in remission 12 months later; conversely, of those in remission at 6 months who did not change therapy recurrence occurred in 31 (41%) of 75 patients 12 months later. Smoking (odds ratio [OR] 2.4, 95% CI 1.2-4.8, p=0.02) and the presence of two or more clinical risk factors including smoking (OR 2.8, 95% CI 1.01-7.7, p=0.05) increased the risk of endoscopic recurrence. The incidence and type of adverse and severe adverse events did not differ significantly between patients in the active care and standard care groups (100 [82%] of 122 vs 45 [87%] of 52; p=0.51) and (33 [27%] of 122 vs 18 [35%] of 52; p=0.36), respectively. Treatment according to clinical risk of recurrence, with early colonoscopy and treatment step-up for recurrence, is better than conventional drug therapy alone for prevention of postoperative Crohn's disease recurrence. Selective immune suppression, adjusted for early recurrence, rather than routine use, leads to disease control in most patients. Clinical risk factors predict recurrence, but patients at low risk also need monitoring. Early remission does not preclude the need for ongoing monitoring.

The aim of the study was to determine whether ghrelin treatment has a protective effect on gene expression and biochemical changes in the stomach of newborn streptozotocin (STZ) induced diabetic rats. In this study, four groups of Wistar rats were used: control, ghrelin control, diabetic and diabetic+ghrelin. The rats were sacrificed after four weeks of treatment for diabetes. The gene expressions of: somatostatin, cholecystokinin, apelin and the altered active caspase-3, active caspase-8, proliferating cell nuclear antigen, were investigated in the pyloric region of the stomach and antioxidant parameters were measured in all the stomach. Although ghrelin treatment to diabetic rats lowered the stomach lipid peroxidation levels, the stomach glutathione levels were increased. Exogenous ghrelin caused an increased activities of stomach catalase, superoxide dismutase, glutathione reductase and glutathione peroxidase in diabetic rats. Numbers of somatostatin, cholecystokinin and proliferating cell nuclear antigen immunoreactive cells decreased in the diabetic+ghrelin group compared to the diabetic group. Apelin mRNA expressions were remarkably less in the diabetic+ghrelin rats than in diabetic rats. The results may indicate that ghrelin treatment has a protective effect to some extent on the diabetic rats. This protection is possibly accomplished through the antioxidant activity of ghrelin observed in type 2 diabetes. Consequently exogenous ghrelin may be a candidate for therapeutic treatment of diabetes. Copyright © 2013 Elsevier GmbH. All rights reserved.

Statin treatment and exercise training can improve lipid profile when administered separately. The efficacy of exercise and statin treatment combined, and its impact on myalgia and serum creatine kinase (CK) have not been completely addressed. The purpose of this study was to determine the effect of statin treatment and the addition of exercise training on lipid profile, including oxidized low-density lipoprotein (oxLDL), and levels of CK and alanine transaminase. Thirty-one hypercholesterolemic and physically inactive subjects were randomly assigned to rosuvastatin (R) or rosuvastatin/exercise (RE) group. A third group of physically active hypercholesterolemic subjects served as an active control group (AC). The R and RE groups received rosuvastatin treatment (10 mg/d) for 20 weeks. From week 10 to week 20, the RE group also participated in a combined endurance and resistive exercise training program (3 d/wk). Lipid profile was determined for all subjects at week 0 (Pre), week 10 (Mid), and week 20 (Post). The CK and alanine transaminase levels were measured at the same time points in the RE and R groups and 48 hours after the first and fifth exercise bout in the RE group. Each RE subject was formally queried about muscle fatigue, soreness, and stiffness before each training session. Total, LDL, and oxLDL cholesterol was lower in the RE and R groups at Mid and Post time points when compared with Pre. Oxidized LDL was lower in the RE group compared with the R group at the Post time point. When treatment groups (R and RE) were combined, high-density lipoprotein levels were increased and triglycerides decreased across time. Creatine kinase increased in the RE group 48 hours after the first exercise bout, but returned to baseline levels 48 hours after the fifth exercise bout. Rosuvastatin treatment decreased total, LDL, and oxLDL cholesterol. The addition of an exercise training program resulted in a further decrease in oxLDL. There was no abnormal sustained increase in CK or reports of myalgia after the addition of exercise training to rosuvastatin treatment.

The main goal of this study was to investigate the efficacy of Botulinum Toxin A (BoNT-A), combined with an individualized intensive physiotherapy/orthoses treatment, in improving upper limb activity and competence in daily activity in children with hemiplegia, and to compare its effectiveness with that of non-pharmacological instruments. It was a Randomized Clinical Trial of 27 children with spastic hemiplegic cerebral palsy, outpatients of two high speciality Centres for child rehabilitation. Each child was assigned by simple randomization to experimental group (BoNT-A) or control group (placebo). Assisting Hand Assessment (AHA) was chosen as primary outcome measure; other measures were selected according to ICF dimensions. Participants were assessed at baseline (T0), at T1, T2, T3 (1-3-6 months after injection, respectively). Every patient was given a specific physiotherapeutic treatment, consisting of individualized goal directed exercises, task oriented activities, daily stretching manoeuvres, functional and/or static orthoses. BoNT-A group showed a significant increase of AHA raw scores at T2, compared to control group (T2-T0: p=.025) and functional goals achievement (GAS) was also slightly better in the same group (p=.033). Other measures indicated some improvement in both groups, without significant intergroup differences. Children with intermediate severity of hand function at House scale for upper limb impairment seem to have a better benefit from BoNT-A protocol. BoNT-A was effective in improving manipulation in the activity domain, in association with individualized goal-directed physiotherapy and orthoses; the combined treatment is recommended. The study brings more evidence for the efficacy of a combined treatment botulinum toxin injection-physiotherapy-orthoses, and it gives some suggestions for candidate selection and individualized treatment.

This study was conducted to evaluate the biochemical effects of grape seed extract against dexamethasone-induced hepatic and renal dysfunction in a female albino rat. Twenty-eight adult female rats were divided randomly into four equal groups: Group 1: animals were injected subcutaneously with saline and consider as normal control one. Group 2: animals were injected subcutaneously with dexamethasone in a dose of 0.1 mg/kg body weight. Group 3: animals were injected subcutaneously with 0.1 mg/kg body weight of dexamethasone, and then treated with a grape seed extract in a dose of 200 mg/kg body weight by oral gavage. Group 4: animals were injected subcutaneously with 0.1 mg/kg body weight of dexamethasone, and then treated with a grape seed extract in a dose of 400 mg/kg body weight by oral gavage. After 4 weeks, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) activities, albumin, uric acid, creatinine, and glucose levels were assayed. Hepatic reduced glutathione (GSH), total protein content, and catalase and glucose-6-phosphate dehydrogenase activities were also assayed. Dexamethasone administration caused elevation of serum levels of glucose, uric acid, creatinine, ALT, AST activities, and a decrease in other parameters such as hepatic glutathione, total protein levels, and catalase enzyme activity. Treatment with Vitis vinifera L. seed extract showed a significant increase in the body weight of rats in the group treated with Vitis vinifera L. seed extract orally compared with the dexamethasone control group. An increase in GSH and catalase activity in response to oral treatment with Vitis vinifera L. seed extract was observed after treatment. Grape seed extract positively affects glucocorticoid-induced hepatic and renal alteration in albino rats. PMID:29051443

One hundred and eighteen AIS patients (99 females and 19 males), treated at the Aarhus University Hospital from January 1, 1987 to December 31, 1997, were investigated with at least 2 years follow-up at the time of receiving a posted self-administered questionnaire. Forty-four patients were treated with Boston brace (B) only, 41 patients had surgery (S), and 33 patients were treated both with brace and surgery (BS). The Cobb angles of the three treatment groups did not differ significantly after completed treatment. The outcome in terms of the total SRS 24 score was not significantly different among the three groups. B patients had a significantly better general (not treatment related) self-image and higher general activity level than the total group of surgically treated patients, while surgically treated patients scored significantly better in post-treatment self-image and satisfaction. Comparing B with BS we found a significantly higher general activity level in B patients, while the BS group had significantly higher satisfaction. There were no significant differences between BS and S patients in any of the domain scores. All treatment groups scored "fair or better" in all domain scores of the SRS 24 questionnaire, except in post-treatment function, where all groups scored worse than "fair". Improvement of appearance by means of surgical correction increases mean scores for post-treatment self-image and post-treatment satisfaction. Double-treatment by brace and surgery does not appear to jeopardize a good final outcome.

Activated carbon (AC) supported Cu catalysts are employed to study the influence of surface oxygenated groups on the formation of active Cu species and the catalytic activity of Cu/AC catalyst for oxidative carbonylation of methanol to dimethyl carbonate (DMC). The AC supports are thermal treated under different temperatures in order to adjust the levels of surface oxygenated groups. The AC supports are characterized by BET, TPD-MS and XRD, and the Cu/AC catalysts are characterized by BET, XRD, TEM, XPS, AAS, CH3OH-TPD and N2O chemisorption. The results show that as the treatment temperature is below 800 °C, the BET surface area of the corresponding AC supports are nearly unchanged and close to that of the original AC (1529.6 m2/g). But as the thermal treatment temperature is elevated from 1000 to 1600 °C, the BET surface area of AC supports gradually decreases from 1407.6 to 972.2 m2/g. After loading of Cu, the BET surface area of copper catalysts is in the range of 834.4 to 1545.3 m2/g, which is slightly less than that of the respective supports. When AC is thermal treated at 400 and 600 °C, the unstable carboxylic acid and anhydrides groups are selectively removed, which has weakened the mobility and agglomeration of Cu species during the calcination process, and thus improve the Cu species dispersion over AC support. But as the treatment temperature is elevated from 600 °C to 1200 °C, the Cu species dispersion begins to decline suggesting further removal of stable surface oxygenated groups is unfavorable for Cu species dispersion. Moreover, higher thermal treatment temperature (above 1200 °C) promotes the graphitization degree of AC and leds to the decrease of Cu loading on AC support. Meanwhile, the removal of surface oxygenated groups by thermal treatment is conducive to the formation of more π-sites, and thus promote the reduction of Cu2+ to Cu+ and Cu0 as active centers. The specific surface area of (Cu+ + Cu0) is improved by thermal treatment of AC, however, the space time yield of DMC on unit specific surface area of (Cu+ + Cu0) is in the range of 23.1-49.1 mg h-1 m-2, which is much less than that (77.6 mg h-1 m-2) of the original catalyst. The possible reason is that the removal of surface oxygenated groups results in AC support transforms from hydrophilicity to hydrophobicity, which is detrimental for the adsorption of CH3OH resulting in the decreased local concentration of CH3OH on active Cu species.

The effects of initiation of continuous positive airway pressure (CPAP) therapy on electroencephalographic (EEG) background activity were investigated in patients exhibiting both moderate (n = 13) and severe (n = 12) obstructive sleep apnea syndromes in the testing of the potential differences of alterations of brain electrical activity caused by chronic hypoxia between these two groups. A normal control group (n = 14) was also examined. Two EEG examinations were achieved in each group: before and after first-time CPAP therapy. Low-resolution electromagnetic tomography (LORETA) was implemented towards localizing the generators of EEG activity in separate frequency bands. Prior to CPAP treatment, as a common direction of change, analysis with LORETA demonstrated increased activity in comparison with the patient and control groups. In the moderate group, significant changes were detected in the alpha2 band in the posterior cingulate cortex as well as in the beta1 band in the right posterior parietal cortex and the left supramarginal gyrus. In the severe group, significant changes were found in theta and alpha1 bands in the posterior cingulate cortex. Following CPAP treatment, these significant differences vanished in the severe group. In the moderate group, significantly decreased activity was seen in the beta3 band in the right fusiform gyrus. These findings potentially suggest a normalizing effect of CPAP therapy on EEG background activity in both groups of obstructive sleep apnea syndrome patients. Compensatory alterations of brain electrical activity in regions associated with influencing successful memory retrieval, emotional perception, default mode network, anorexia and fear network caused by chronic intermittent hypoxia could possibly be reversed with the use of CPAP therapy. © 2016 European Sleep Research Society.

The study explores whether messages about the physical activity levels of the majority (i.e. normative messages) affect young adults' intention to engage in regular physical activity. An experimental survey among 16 to 24 year-olds in Bulgaria, Croatia and Romania (n = 1200) was conducted in March 2013. A control group received no message; one treatment group was told that the majority was physically active (positive message); and another treatment group was told that the majority was not physically active (negative message). Both the positive and (unexpectedly) the negative normative messages showed a significant and positive effect on intention to be physically active. There was no difference between the effects of the messages. Normative messages affect intention, which is encouraging for public health campaigns. The effect of the positive message confirms previous findings on conformity to the norm; the effect of the negative message is unexpected and requires further research to be understood.

Objective To identify pain-related behaviors and assess the effects of butorphanol tartrate and morphine sulfate in koi (Cyprinus carpio) undergoing unilateral gonadectomy. Design Prospective study. Animals 90 adult male and female koi. Procedures Each fish received saline (0.9% NaCl) solution (which is physiologically compatible with fish) IM, butorphanol (10 mg/kg [4.5 mg/lb], IM), or morphine (5 mg/kg [2.3 mg/lb], IM) as an injection only (6 fish/treatment); an injection with anesthesia and surgery (12 fish/treatment); or an injection with anesthesia but without surgery (12 fish/treatment). Physiologic and behavioral data were recorded 12 hours before and at intervals after treatment. Results Compared with baseline values, the saline solution–surgery group had significantly decreased respiratory rates (at 12 to 24 hours), food consumption assessed as a percentage of floating pellets consumed (at 0 to 36 hours), and activity score (at 0 to 48 hours). Respiratory rate decreased in all butorphanol-treated fish; significant decreases were detected at fewer time points following morphine administration. In the butorphanol-surgery group, the value for food consumption initially decreased but returned to baseline values within 3 hours after treatment; food consumption did not change in the morphine-surgery group. Surgery resulted in decreased activity, regardless of treatment, with the most pronounced effect in the saline solution–surgery group. Changes in location in water column, interactive behavior, and hiding behavior were not significantly different among groups. Butorphanol and morphine administration was associated with temporary buoyancy problems and temporary bouts of excessive activity, respectively. Conclusions and Clinical Relevance Butorphanol and morphine appeared to have an analgesic effect in koi, but morphine administration caused fewer deleterious adverse effects. Food consumption appeared to be a reliable indicator of pain in koi. PMID:24004238

To investigate effects of mandible advanced device (MAD) therapy for obstructive sleep apnoea-hypopnea syndrome (OSAHS) on the neuron apoptosis and acetylcholine esterase activity in frontal cortex. Thirty male New Zealand white rabbits were randomly divided into three groups (n = 10 in each group): group OSAHS, group MAD, and control group. Hydrophilic polyacrylamide gel was injected into soft palate of the animals to induce OSAHS in group OSAHS and group MAD. The group MAD animals wore MAD to relief the obstructiveness. The control group was not given any treatment. Computed tomography (CT) examination of the upper airway and polysomnography (PSG) recordings were performed in supine position. All rabbits were induced to sleep in a supine position for 4 to 6 hours every day and were observed for consecutive 8 weeks. The frontal cortices of three groups were dissected and the neuron apoptosis was detected by terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) and flow cytometry. Acetylcholine esterase (AchE) activity in the frontal cortex was measured by spectrophotometry. The group OSAHS exhibited high neuron apoptosis rate and low AchE activity than those of group MAD and control group. The blood oxygen saturation was negatively correlated with neuronal apoptosis rate and positively correlated with AchE activity. Applying MAD in OSAHS animals significantly improve the neuronal damage and function deficits by apnoea-hypoxia caused by narrowed upper airway. This study provided evidence that MAD therapy for OSAHS can significantly decrease neuronal apoptosis and increase AchE activity in the frontal cortex.

To investigate the anti-inflammatory effects of simvastatin in rats undergoing one-lung ventilation (OLV) followed by lung re-expansion. Male Wistar rats (n=30) were submitted to 1-h OLV followed by 1-h lung re-expansion. Treated group received simvastatin (40 mg/kg for 21 days) previous to OLV protocol. Control group received no treatment or surgical/ventilation interventions. Measurements of pulmonary myeloperoxidase (MPO) activity, pulmonary protein extravasation, and serum levels of cytokines and C-reactive protein (CRP) were performed. OLV significantly increased the MPO activity in the collapsed and continuously ventilated lungs (31% and 52% increase, respectively) compared with control (p<0.05). Treatment with simvastatin significantly reduced the MPO activity in the continuously ventilated lung but had no effect on lung edema after OLV. The serum IL-6 and CRP levels were markedly higher in OLV group, but simvastatin treatment failed to affect the production of these inflammatory markers. Serum levels of IL-1β, TNF-α and IL-10 remained below the detection limit in all groups. In an experimental one-lung ventilation model pre-operative treatment with simvastatin reduces remote neutrophil infiltration in the continuously ventilated lung. Our findings suggest that simvastatin may be of therapeutic value in OLV-induced pulmonary inflammation deserving clinical investigations.

Epidemiological data imply links between the increasing incidences of Alzheimer's disease (AD) and type 2 diabetes mellitus. In this study, an AD rat model was established by combining treatments with intracerebroventricular streptozotocin (icv-STZ) and subcutaneous D-galactose, and the effects of curcumin on depressing AD-like symptoms were investigated. In the AD model group, rats were treated with icv-STZ in each hippocampus with 3.0 mg/kg of bodyweight once and then were subcutaneously injected with D-galactose daily (125 mg/kg of bodyweight) for 7 weeks. In the curcumin-protective group, after icv-STZ treatment, rats were treated with D-galactose (the same as in the AD model group) and intraperitoneally injected with curcumin daily (10 mg/kg of bodyweight) for 7 weeks. Vehicle-treated rats were treated as control. Compared with the vehicle control, the amount of protein carbonylation and glutathione in liver, as well as malondialdehyde in serum, were upregulated but glutathione peroxidase activity in blood was downregulated in the AD model group. The shuttle index and locomotor activity of rats in the AD model group were decreased compared with the vehicle control group. Furthermore, AD model rats showed neuronal damage and neuron loss with formation of amyloid-like substances and neurofibrillary tangles, and the levels of both β-cleavage of AβPP and phosphorylation of tau (Ser396) were significantly increased compared with the vehicle control group. Notably, compared with the AD model group, oxidative stress was decreased and the abilities of active avoidance and locomotor activity were improved, as well as attenuated neurodegeneration, in the curcumin-protective group. These results imply the applications of this animal model for AD research and of curcumin in the treatment of AD.

Ample evidence suggests that cancer is triggered by mutagenic damage and diets or supplements capable of reducing such incidences can be related to the prevention of neoplasy development or to an improvement in life quality of patients who undergo chemotherapy. This research aimed to evaluate the antimutagenic and antigenotoxic activity of β-glucan. We set up 8 experimental groups: control (Group 1), cyclophosphamide (Group 2), Groups 3-5 to assess the effect of β-glucan administration, and Groups 6-8 to evaluate the association between cyclophosphamide and β-glucan. The intraperitonial concentrations of β-glucan used were 100, 150 and 200 mg/kg. Micronucleus and comet assays showed that within the first week of treatment β-glucan presented a damage reduction rate between 100-62.04% and 94.34-59.52% for mutagenic and genotoxic damages, respectively. This activity decreased as the treatment was extended. During the sixth week of treatment antimutagenicity rates were reduced to 59.51-39.83% and antigenotoxicity was not effective. This leads to the conclusion that the efficacy of β-glucan in preventing DNA damage is limited when treatment is extended, and that its use as a chemotherapeutic adjuvant need to be better clarified.

The effects of soybean oligosaccharides (SBOS) on antioxidant enzyme activities and insulin resistance in pregnant women with gestational diabetes mellitus (GDM) were investigated. Ninety-seven pregnant women with GDM were randomly divided into two groups, the control group (51 cases) and the SBOS group (46 cases). Before the group separation, the blood sugar level in patients was maintained stable by regular diet and insulin treatment. The control group was continued with the insulin treatment, while the SBOS group was treated with the combination of insulin and SBOS. Results showed that SBOS were able to reduce oxidative stress and alleviate insulin resistance in pregnant women with GDM, which indicates that SBOS may play an important role in the control of GDM complications.

To investigate the course of active inflammatory and fatty lesions seen on magnetic resonance imaging (MRI) in patients with early axial spondyloarthritis (SpA) treated with the tumor necrosis factor (TNF) inhibitor infliximab added to naproxen as compared to those treated with naproxen alone. A total of 158 patients with active axial SpA were randomized (2:1) to receive 28 weeks of treatment with either infliximab 5 mg/kg plus naproxen 1,000 mg/day or placebo plus naproxen 1,000 mg/day. MRI of the sacroiliac (SI) joints and of the spine was performed at baseline and week 28. Images were scored for active inflammation and for fatty lesions. After 28 weeks, there was a significant reduction of inflammation in the spine and in the SI joints in both treatment groups, which was, however, more prominent in the infliximab plus naproxen group (mean ± SD spine osteitis change score -2.9 ± 5.1, versus -2.0 ± 4.2 in the placebo plus naproxen group [P < 0.001]; SI joint osteitis change score -4.3 ± 5.2 in the infliximab plus naproxen group versus -3.9 ± 3.7 in the placebo plus naproxen group [P = 0.003]). Similarly, there was a significant increase in the fatty lesion score after 28 weeks in both groups; this change did not, however, differ significantly between groups (spine fatty lesion change score 0.8 ± 1.7 in the infliximab plus naproxen group versus 1.0 ± 1.8 in the placebo plus naproxen group [P = 0.72]; SI joint fatty lesion change score 1.7 ± 2.7 in the infliximab plus naproxen group versus 1.4 ± 2.6 in the placebo plus naproxen group [P = 0.86]). These findings indicate that effective antiinflammatory treatment of axial SpA is associated with an increase in fatty lesion scores, independent of concomitant treatment with or without anti-TNF. © 2016, American College of Rheumatology.

This study evaluates serum creatine kinase isoenzyme activity in children with osteogenesis imperfecta to determine its usefulness as a biochemical marker during treatment with bisphosphonate. The changes of creatine kinase (CK) isoenzyme activity during and after discontinuation therapy were observed. These results could be useful in addressing over-treatment risk prevention. The brain isoenzyme of creatine kinase (CKbb) is highly expressed in mature osteoclasts during osteoclastogenesis, thus plays an important role in bone resorption. We previously identified high serum CKbb levels in 18 children with osteogenesis imperfect (OI) type 1 treated for 1 year with bisphosphonate (neridronate). In the present study, serum CK isoenzymes were evaluated in the same children with continuous versus discontinued neridronate treatment over a further 2-year follow-up period. This study included 18 children with OI type 1, 12 with continued (group A) and 6 with ceased (group B) neridronate treatment. Auxological data, serum biochemical markers of bone metabolism, bone mineral density z-score, and serum total CK and isoenzyme activities were determined in both groups. Serum CKbb was progressively and significantly increased in group A (p < 0.004) but rapidly decreased to undetectable levels in group B. In both groups, the cardiac muscle creatine kinase isoenzyme (CKmb) showed a marked decrease, while serum C-terminal telopeptide (CTx) levels were almost unchanged. This study provides evidence of the cumulative effect of neridronate administration in increasing serum CKbb levels and the reversible effect after its discontinuation. This approach could be employed for verifying the usefulness of serum CKbb as a biochemical marker in patients receiving prolonged bisphosphonate treatment. Moreover, the decreased serum CKmb levels suggest a systemic effect of these drugs.

The aim of this study was to assess whether the combination of low frequency repetitive transcranial magnetic stimulation (rTMS) and venlafaxine (150-225 mg/day) is effective and safe for treatment-resistant unipolar depression (TRD). In a multicenter (18 centers) randomized double blind controlled trial with three arms, 170 patients were allocated to receive active rTMS combined with active venlafaxine (n = 55), active rTMS combined with placebo venlafaxine (n = 60) or sham rTMS combined with active venlafaxine (n = 55). The patients received once daily sessions of active or sham 1 Hz rTMS applied over the right dorsolateral prefrontal cortex (360 pulses/day delivered at 120% of the resting motor threshold) for two to six weeks; rTMS was combined with active or sham venlafaxine (mean dose: 179.0 ± 36.6 mg/day). The primary outcome was the number of patients who achieved remission, which was defined as an HDRS17 score <8. We reported a similar significant antidepressant effect in the 3 groups (P < 10(-6)), with a comparable delay of action and a comparable number of remitters at the endpoint (28% in the combination group, 41% in the rTMS group and 43% in the venlafaxine group; P = 0.59). Low frequency rTMS appears to be as effective as venlafaxine and as effective as the combination of both treatments for TRD. Because of its short session duration (the duration of one session was 8.5 min) and its safety, slow rTMS might be a useful alternative treatment for patients with TRD. Copyright © 2014 Elsevier Inc.

Evidence reveals that histone deacetylase (HDAC) inhibition has potential for the treatment of inflammatory diseases. The protective effect of HDAC inhibition involves multiple mechanisms. Heme oxygenase-1 (HO-1) is protective in lung injury as a key regulator of antioxidant response. The authors examined whether HDAC inhibition provided protection against ischemia-reperfusion (I/R) lung injury in rats by up-regulating HO-1 activity. Acute lung injury was induced by producing 40 min of ischemia followed by 60 min of reperfusion in isolated perfused rat lungs. The rats were randomly allotted to control group, I/R group, or I/R + valproic acid (VPA) group with or without an HO-1 activity inhibitor (zinc protoporphyrin IX) (n = 6 per group). I/R caused significant increases in the lung edema, pulmonary arterial pressure, lung injury scores, tumor necrosis factor-α, and cytokine-induced neutrophil chemoattractant-1 concentrations in bronchoalveolar lavage fluid. Malondialdehyde levels, carbonyl contents, and myeloperoxidase-positive cells in lung tissue were also significantly increased. I/R stimulated the degradation of inhibitor of nuclear factor-κB-α, nuclear translocation of nuclear factor-κB, and up-regulation of HO-1 activity. Furthermore, I/R decreased B-cell lymphoma-2, heat shock protein 70, acetylated histone H3 protein expression, and increased the caspase-3 activity in the rat lungs. In contrast, VPA treatment significantly attenuated all the parameters of lung injury, oxidative stress, apoptosis, and inflammation. In addition, VPA treatment also enhanced HO-1 activity. Treatment with zinc protoporphyrin IX blocked the protective effect of VPA. VPA protected against I/R-induced lung injury. The protective mechanism may be partly due to enhanced HO-1 activity following HDAC inhibition.

To evaluate efficacy and safety, baricitinib [Janus kinase (JAK) 1/JAK2 inhibitor] was compared with placebo in Japanese patients with active rheumatoid arthritis (RA) despite background treatment with methotrexate (MTX). This was a phase IIB, double-blind, randomized, placebo-controlled study (clinicaltrials.gov: NCT01469013). Patients had moderate to severe active adult-onset RA despite stable treatment with MTX. Patients (n = 145) were randomized in a 2:1:1:1:1 ratio to placebo or 1 mg, 2 mg, 4 mg, or 8 mg oral baricitinib daily for 12 weeks. The primary analysis compared the combined 4/8-mg dose groups with placebo for the American College of Rheumatology (ACR) 20 response rate at 12 weeks. Other outcomes included additional measures of disease activity, physical function, laboratory abnormalities, and adverse events. A significantly higher proportion of patients in the combined 4/8-mg baricitinib group (37/48, 77%) compared with the placebo group (15/49, 31%) had at least an ACR20 response after 12 weeks of treatment (p < 0.001). Significant improvements in disease activity, remission, and physical function were observed as early as Week 2 of treatment with baricitinib, particularly with daily doses of ≥ 4 mg. Only 1 patient receiving baricitinib discontinued because of an adverse event. Adverse event rates with baricitinib doses ≤ 4 mg daily were similar to placebo, but there was a higher incidence of adverse events and laboratory abnormalities in the 8-mg group. In this phase II study, baricitinib was well tolerated and rapidly improved the signs, symptoms, and physical function of Japanese patients with active RA, supporting continued development of baricitinib (clinicaltrials.gov NCT01469013).

The present study aims to assess the pulp vitality before and after different tooth bleaching procedures, in order to determine the changes in pulpal microcirculation and whether they are reversible or not. Twelve volunteers were included in this study. For each volunteer, the pulpal blood flow of maxillary teeth was assessed prior to treatment using Laser Doppler Flowmetry. The "in office" bleaching technique was used 6 anterior teeth, with two different gels, a conventional one chemically activated (Group I 3teeth) and another one activated using Nd:YAG laser (Group II-3 teeth). The bleaching agents were applied on counterpart teeth and, after obtaining a esthetic results for each tooth, the pulpal blood flow was assessed using Laser Doppler Flowmetry immediately after treatment and then after one day and one week. All data were collected and statistically analyzed. Immediately after treatment, the assessment showed an increase of pulpal blood flow, for both study groups, but higher in Group I as compared to Group II (p<0.005). The subsequent assessments showed a reduction of the pulpal blood flow with non - significant differences between the study groups (p<0.005).The results suggest that the tooth bleaching procedurere presents a safe treatment method, which does not lead to irreversible damage to the dental pulp, when used correctly.

We present a novel approach for characterizing surfaces utilizing super-resolution fluorescence microscopy with subdiffraction limit spatial resolution. Thermoplastic surfaces were activated by UV/O3 or O2 plasma treatment under various conditions to generate pendant surface-confined carboxylic acids (-COOH). These surface functional groups were then labeled with a photoswitchable dye and interrogated using single-molecule, localization-based, super-resolution fluorescence microscopy to elucidate the surface heterogeneity of these functional groups across the activated surface. Data indicated nonuniform distributions of these functional groups for both COC and PMMA thermoplastics with the degree of heterogeneity being dose dependent. In addition, COC demonstrated relative higher surface density of functional groups compared to PMMA for both UV/O3 and O2 plasma treatment. The spatial distribution of -COOH groups secured from super-resolution imaging were used to simulate nonuniform patterns of electroosmotic flow in thermoplastic nanochannels. Simulations were compared to single-particle tracking of fluorescent nanoparticles within thermoplastic nanoslits to demonstrate the effects of surface functional group heterogeneity on the electrokinetic transport process.

To elucidate the key biochemical indexes associated with 1, 2-dimethylhydrazine (DMH)-induced colon carcinogenesis and the modulatory efficacy of a dietary polyphenol, ellagic acid (EA). Wistar rats were chosen to study objective, and were divided into 4 groups; Group 1-control rats; Group 2-rats received EA (60 mg/kg body weight/day, orally); rats in Group 3-induced with DMH (20 mg/kg body weight) subcutaneously for 15 weeks; DMH-induced Group 4 rats were initiated with EA treatment. We examined key citric acid cycle enzymes such as isocitrate dehydrogenase, alpha-ketoglutarate dehydrogenase, succinate dehydrogenase, malate dehydrogenase and the activities of respiratory chain enzymes NADH dehydrogenase and Cytochrome-C-oxidase and membrane-bound enzyme profiles (Na +/K + ATPase, Ca 2+ ATPase and Mg 2+ ATPase), activities of lysosomal proteases such as β-D-glucuronidase, β-galactosidase and N-acety-β-D-glucosaminidase and cellular thiols (oxidized glutathione, protein thiols, and total thiols). It was found that administration of DMH to rats decreased both mitochondrial and membrane-bound enzymes activities, increased activities of lysosomal enzymes and further modulates cellular thiols levels. Treatment with EA significantly restored the mitochondrial and ATPases levels and further reduced lysosomal enzymes to near normalcy thereby restoring harmful effects induced by DMH. EA treatment was able to effectively restore the detrimental effects induced by DMH, which proves the chemoprotective function of EA against DMH-induced experimental colon carcinogenesis.

The aim of this study was to assess the effect of peloid on pain, functionality, daily life activities, and quality of life of lateral epicondylitis (LE) patients. In this randomized, controlled, single-blind study, 75 patients who were diagnosed with chronic LE were enrolled to the study. Patients were randomized into two groups using the random number table. The patients in the first group (group 1) ( n = 33), were given lateral epicondylitis band (LEB) (during the day for 6 weeks) + peloid therapy (five consecutive days a week for 2 weeks), and the second group (group 2) ( n = 32), received LEB treatment alone. The patients were assessed by using Patient Rated Tennis Elbow Evaluation (PRTEE) and Nottingham Health Profile (NHP). The data were obtained before treatment (W0), immediately after treatment (W2), and 1 month after treatment (W6). In analysis of the collected data, the Wilcoxon signed rank test for intra-group comparisons and Mann-Whitney U test for comparisons between groups were used. Both in groups 1 and 2, there was a statistically significant improvement in all the evaluation parameters at W2 and W6 when compared to W0 ( p < 0.05). In comparison of difference scores between groups, although there was no statistically significant difference between the two groups at W2 when compared to W0 ( p > 0.05), a statistically significant difference was found in favor of group 1 for all the evaluation parameters at W6 ( p < 0.05). Our results have shown that peloid treatment could be effective in providing improvement in pain relief, function, daily life activities, and quality of life in LE patients.

Hepatic fibrosis is a common feature of chronic liver injury, and the involvement of angiotensin II in such process has been studied earlier. We hypothesized that anti-angiotensin II agents may be effective in preventing hepatic fibrosis. In this study, Long Evans female rats were used and divided into four groups such as Group-I, Control; Group-II, Control + ramipril; Group-III, CCl4; and Group-IV, CCl4 + ramipril. Group II and IV are treated with ramipril for 14 d. At the end of treatment, the livers were removed, and the level of hepatic marker enzymes (aspartate aminotransferase, Alanine aminotransferase, and alkaline phosphatase), nitric oxide, advanced protein oxidation product , catalase activity, and lipid peroxidation were determined. The degree of fibrosis was evaluated through histopathological staining with Sirius red and trichrome milligan staining. Carbon-tetrachloride (CCl4) administration in rats developed hepatic dysfunction and raised the hepatic marker enzymes activities significantly. CCl4 administration in rats also produced oxidative stress, inflammation, and fibrosis in liver. Furthermore, angiotensinogen-inhibitor ramipril normalized the hepatic enzymes activities and improved the antioxidant enzyme catalase activity. Moreover, ramipril treatment ameliorated lipid peroxidation and hepatic inflammation in CCl4-treated rats. Ramipril treatment also significantly reduced hepatic fibrosis in CCl4-administered rats. In conclusion, our investigation suggests that the antifibrotic effect of ramipril may be attributed to inhibition of angiotensin-II mediated oxidative stress and inflammation in liver CCl4-administered rats.

A potent antioxidant, selenium might modulate dementia-induced progression of brain and blood oxidative and apoptotic injuries. The present study explores whether selenium protects against experimental dementia (scopolamine, SCOP)-induced brain, and blood oxidative stress, apoptosis levels, and cytokine production in rats. Thirty-two rats were equally divided into four groups. The first group was used as an untreated control. The second group was treated with SCOP to induce dementia. The third and fourth groups received 1.5 mg/kg selenium (sodium selenite) and SCOP + selenium, respectively. Dementia was induced in the second and forth groups by intraperitoneal SCOP (1 mg/kg) administration. Brain, plasma, and erythrocyte lipid peroxidation levels as well as plasma TNF-α, interleukin (IL)-1β, and IL-4 levels were high in the SCOP group though they were low in selenium treatments. Selenium and selenium + SCOP treatments increased the lowered glutathione peroxidase activity, reduced glutathione, vitamins A and E concentrations in the brain, erythrocytes and plasma of the SCOP group. Apoptotic value expressions as active caspase-3, procaspase-9, and PARP were also increased by SCOP, while they were decreased by selenium and selenium + SCOP treatments. In conclusion, selenium induced protective effects against experimental dementia-induced brain, and blood oxidative injuries and apoptosis through regulation of cytokine production, vitamin E, glutathione concentrations, and glutathione peroxidase activity.

R. tomentosus is a vegetal species closely related to the culinary rosemary (R. officinalis), a plant reported to contain antihepatotoxic agents. A dried ethanol extract of the aerial parts of Rosmarinus tomentosus (Lamiaceae) and its major fraction separated by column chromatography (fraction F19) were evaluated for antihepatotoxic activity in rats with acute liver damage induced by a single oral dose of thioacetamide. Silymarin was used as a reference antihepatotoxic substance. Pre-treatment with R. tomentosus ethanol extract, fraction F19 or silymarin significantly reduced the impact of thioacetamide toxicity on plasma protein and urea levels as well as on plasma aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase and gamma-glutamyl transpeptidase activities compared with thioacetamide-treated animals (group T). Pre-treatment with R. tomentosus ethanol extract significantly reduced the impact of thioacetamide damage on alkaline phosphatase and gamma-glutamyl transpeptidase activities compared with group T. Silymarin administration significantly reduced alkaline phosphatase and gamma-glutamyl transpeptidase activities compared with group T. Fraction F19 administration reduced only alkaline phosphatase activity compared with group T. According to these data, R. tomentosus extract shows promising antihepatotoxic activity, suggesting the need to isolate the chemical principles responsible for this activity and to study this activity in a model of thioacetamide-induced cirrhosis.

Very few clinical cognitive-behavioural intervention (CBI) studies were conducted with the Chinese gamblers. There is a lack of attention paid to intervening in negative emotions that may also adversely affect PGs in current CBI treatment modality. This study is the first attempt to systematically and rigorously evaluate both the short-term and longer-term effects of a culturally-attuned CBI group treatment with an emotion regulation component for a group of Chinese PGs in Hong Kong. A quasi-experimental matched-pairs design was adopted and 84 participants were allocated to the CBI (N = 42) and social activity groups (N = 42). There are 3 assessment points in the study: baseline at recruitment, post-intervention at the end of CBI and social activity groups, and at 6-month follow-up. When compared to the social activity group and after controlling for general group effects, there were significantly greater decreases in the severity of gambling, gambling-related cognitions (i.e. interpretive bias), negative psychological states (i.e. stress) and money spent on gambling in the past month in the CBI group between pre- and post-intervention and between pre-intervention and 6-month follow-up. Results also indicated that both reduction in gambling-related cognitions and negative psychological states could mediate the treatment effect of the CBI on the reduction of problematic gambling behaviours. The culturally attuned integrated CBI group treatment with an emotional regulation component appeared to be effective in treating Chinese problem gamblers in Hong Kong and the effects could be sustained at 6-month follow-up.

The study was designed to evaluate the anticoccidial activity of the methanolic extract of Musa paradisiaca root in chickens. The chickens were divided into six groups of 12 chickens each. Each chicken in five groups was infected with 8,000 infective coccidia (Eimeria tenella) oocysts at day 28 of age while one group served as uninfected control. At day 7 post-infection, two chickens remaining in each group were sacrificed for postmortem examination to confirm coccidiosis. Also at day 7 post-infection, each chicken in four infected groups was given graded doses (250, 500 and 1,000 mg/kg b.w.) of the extract or amprolium (conventional drug). Two groups (an infected and uninfected group) did not receive treatment. Parameters used to assess progress of infection and response to treatment included clinical signs typical of coccidiosis, oocyst count per gramme of faeces (OPG) and packed cell volume (PCV). Treatment of previously infected chickens with M. paradisiaca root extract resulted in a progressive decrease in severity of observed clinical signs, marked reductions in OPG and a gradual increase in PCV. In each case, the changes were dose dependent. There was no significant difference in mean OPG and mean PCV of the extract (at 1,000 mg/kg b.w.) and amprolium-treated groups at termination of the study (at day 50 of age). In the acute toxicity study, the extract was found to be non-toxic to the chickens even at the highest dose of 4,000 mg/kg b.w. The results of this study demonstrated that the extract has anticoccidial activity in a dose-dependent manner and at a dosage of 1,000 mg/kg b.w. had similar efficacy with amprolium in the treatment of chicken coccidiosis.

Background The incidence of lung cancer is increasing with longer life expectancy. Refusal of active treatment for cancer is prone to cause patients to experience more severe symptoms and shorten survival. The purpose of this study was to define the factors related to refusal or abandonment of active therapy in lung cancer. Methods We retrospectively reviewed the data of 617 patients from medical records from 2010 to 2014. Two groups were formed: 149 patients who refused anti‐cancer treatment and allowed only palliative care were classified into the non‐treatment group, while the remaining 468 who received anti‐cancer treatment were classified into the treatment group. Results The groups differed significantly in age, employment, relationship status, number of offspring, educational status, body mass index, presence of chest and systemic symptoms, Charlson Comorbidity Index, Eastern Cooperative Oncology Group score, and tumor node metastasis stage (P < 0.05). In logistic regression analysis, age (odds ratio [OR] 1.10, 95% confidence interval [CI] 1.07–1.13), educational status lower than high school (OR 1.95, 95% CI 1.2–3.2), no history of surgery (OR 2.29, 95% CI 1.4–3.7), body mass index < 18.5 (OR 2.49, 95% CI 1.3–4.7), and a high Eastern Cooperative Oncology Group score of 3 or 4 (OR 5.02, 95% CI 2.3–10.8) were significant factors for refusal of cancer treatment. Conclusion Individual factors, such as old age, low educational status, low weight, and poor performance status can influence refusal of cancer treatment in patients with lung cancer, and should be considered prior to consultation with patients.

To collect visualized proof of Tianmagouteng particles (TMGTP) in alleviating cognitive dysfunction and to explore its effects on brain activity in spontaneously hypertensive rats (SHRs) with hyperactivity of liver-yang (Gan Yang Shang Kang, GYSK). Sixteen SHRs were randomized into treatment group and non-treatment. The SHR with GYSK was induced by gavaging aconite decoction (10mL/kg at 0.2g/mL). After the SHR models were prepared, the rats in the treatment group were administered TMGTP (10mL/kg) once a day for 14days.The rats in the non-treatment group or normal rats (control group) received an equivalent volume of saline. Morris water maze test was conducted before and after the treatment to observe cognitive function. Fluorine 18-deoxy glucose [F-18]FDG micro-PET brain imaging scans was performed after treatment. Data were analyzed with two-sample t-test (P<0. 001) using SPM2 image analysis software. Compared with the non-treatment group, the escape latency significantly decreased but the frequency of entrance into the target zone significantly increased in the treatment group. Consistent with the alteration of cognitive functions, TMGTP induced strong brain activity in the following sites: right dorsolateral nucleus and ventrolateral nucleus of thalamus, amygdala, left met thalamus, cerebellum leaflets, original crack, front cone crack, loop-shaped leaflets; but deactivation of right medial frontal gyrus, bilateral corpus callosum, hippocampus, and left dentate gyrus. TMGTP could alleviate cognitive dysfunction in SHRs with GYSK, which was possibly by inducing alteration of glucose metabolism in different brain regions with corresponding functions.

Re-exposure to conditioned drug stimuli triggers re-consolidation processes. In the present study post-trial apomorphine treatments were administered in order to interact with the re-consolidation of an apomorphine conditioned/sensitized locomotor response. A low (0.05 mg/kg) and a high (2.0mg/kg) dose were used to inhibit or to enhance dopamine activity, respectively. Initially, groups received 5 daily apomorphine (2.0mg/kg)/vehicle treatments either paired or unpaired to open-field placement. The paired treatments generated a progressive locomotor response. Subsequently, all groups received a 5 min non-drug test for conditioning and a conditioned locomotor response was observed in the paired group. The groups received another apomorphine (2.0mg/kg)/vehicle treatment as a re-induction treatment. At this stage the post-trial protocol was initiated. One set of paired, unpaired and vehicle groups were given a low dose of apomorphine (0.05 mg/kg) post-trial; another set received a high dose of apomorphine (2.0mg/kg) post-trial. The remaining group set received vehicle post-trial. The low dose post-trial treatment eliminated the conditioned and sensitized locomotor response and the high dose post-trial treatment enhanced the conditioned and sensitized locomotor response. The efficacy of the post-trial apomorphine treatments to modify the conditioned and the sensitized response after a brief non-drug exposure to test cues supports the proposition that exteroceptive cues control conditioning and sensitization and that the interoceptive drug cues make little or no associational contribution to apomorphine conditioning and sensitization. In addition, the findings point to the importance of dopamine activation in both the acquisition and re-consolidation of conditioning processes. Copyright © 2012 Elsevier B.V. All rights reserved.

Intrathecal baclofen (ITB) treatment is applied in patients with spastic cerebral palsy (SCP), dystonic cerebral palsy (DCP) and progressive neurological disease (PND). Our aim was to investigate whether ITB treatment has a different effect on activities of daily life (ADL) in these groups. A retrospective and cross-sectional survey was conducted using a questionnaire to assess the qualitative effect of ITB (Likert scale) on different domains of functioning (mobility, personal care, communication, comfort) and satisfaction with the results. Groups were compared using non-parametric statistics. Questionnaires were completed for 68 patients (39 SCP, 13 DCP, 16 PND). Satisfaction scores were relatively high in all groups (7-8) and the positive effect on personal care and communication was similar in all groups. The PND group had the shortest follow-up and scored significantly less favourably for the effect on mobility and comfort. This is the first study to show that ITB treatment has similar effects on personal care and communication in stable and progressive neurological disease. The decrease in mobility in the PND group is likely due to the progressive nature of the disease. The different effect on comfort between groups is mainly due to the smaller effect on startles in the PND group. Copyright © 2016 European Paediatric Neurology Society. Published by Elsevier Ltd.

There are few physical activity (PA) interventions in higher education, and they have been only minimally effective. To determine if a course-based, peer education intervention was associated with increases in PA and physical fitness. Participants were 178 students enrolled in a personal health class during the 2007-2008 academic year. A quasi-experimental design was used to assess the effect of the intervention. Repeated measures analysis of covariance was employed to test the impact of the intervention on students' PA, body composition, waist-to-hip ratio, cardiovascular fitness, flexibility, and muscular strength. Women in the treatment group classified as "Inactive" at baseline increased PA, whereas "Inactive" control women had reductions in PA. Women in the treatment group who were "Active" at baseline reduced their waist-to-hip ratio and increased flexibility. There were no differences by treatment group among men. The intervention was effective in improving PA and physical fitness among college women.

The primary gingivoperiosteoplasty by Millard consists of presurgical active orthognathic treatment ('Latham device') of the alveolar margins at the age of 3 months and of surgical closure of the alveolar cleft with local gingivoperiosteal flaps at the age of 5 months. The aim of this investigation was to analyse the facial growth following this treatment. The following material was studied: lateral head X-rays and plaster casts from 146 patients with unilateral (UCLP) and bilateral (BCLP) clefts of lip and palate from birth to 16 years of age. Ninety-one of these patients formed the control group, who received neither gingivoperiosteoplasty nor pre-surgical active orthognathic treatment. The same surgeon and orthodontist treated all 146 patients. A three-dimensional growth disturbance after gingivoperiosteoplasty was observed: 42% patients with UCLP and 40% patients with BCLP had an 'open bite' following closure of the alveolar cleft (control group 5%/10%). The length of the upper jaw in patients who underwent gingivoperiosteoplasty was shorter than in the control group. The frequency of posterior cross bite was also higher in the gingivoperiosteoplasty group. These results demonstrate that treatment with a 'Latham device' disturbs facial growth. Therefore, this treatment should be abandoned.

Children with chronic hepatitis B (CHB) represent an area of unmet medical need, due to increased lifetime risk of CHB sequelae and limited therapeutic options compared with adult CHB patients. The PEG-B-ACTIVE (NCT01519960) phase III study evaluated peginterferon (PegIFN) alfa-2a treatment in children aged 3 to <18 years with CHB. A total of 161 hepatitis B e antigen (HBeAg)-positive immune-active patients without advanced fibrosis/cirrhosis were randomized (2:1) to PegIFN alfa-2a (Group A, n = 101) or no treatment (Group B, n = 50); patients with advanced fibrosis were assigned to PegIFN alfa-2a (Group C, n = 10). PegIFN alfa-2a was administered for 48 weeks by body surface area category, based on 180 µg/1.73m 2 . HBeAg seroconversion rates at 24 weeks post-treatment were significantly higher in Group A (25.7% vs. 6%, P = 0.0043), as were the rates of Hepatitis B s antigen (HBsAg) clearance (8.9% vs. 0%, P = 0.03), hepatitis B virus (HBV) DNA <2,000 IU/mL (28.7% vs. 2.0%, P < 0.001) or undetectable (16.8% vs. 2.0%, P = 0.0069), and alanine aminotransferase (ALT) normalization (51.5% vs. 12%, P < 0.001). Safety, including incidence of ALT flares and neutropenia, was comparable to the established PegIFN alfa-2a profile in HBV-infected adults or hepatitis C virus-infected children. Changes in growth parameters were minimal during treatment and comparable to those in untreated patients. Safety and efficacy outcomes in Group C were in line with Group A. PegIFN alfa-2a treatment of children in the immune-active phase of CHB was efficacious and well tolerated, and associated with higher incidence of HBsAg clearance than in adults. This represents an important advance to the treatment options for children with CHB. This article is protected by copyright.

To compare the event-related potentials (ERPs) and brain topographic maps characteristic and change in normal controls and subjective tinnitus patients before and after repetitive transcranial magnetic stimulation (rTMS) treatment. The ERPs and brain topographic maps elicited by target stimulus were compared before and after 1-week treatment with rTMS in 20 subjective tinnitus patients and 16 healthy controls. Before rTMS, target stimulus elicited a larger N1 component than the standard stimuli (repeating sounds)in control group but not in tinnitus patients. Instead, the tinnitus group pre-treatment exhibited larger amplitude of N1 in response to standard stimuli than to deviant stimuli. Furthermore tinnitus patients had smaller mismatch negativity (MMN) and late discriminative negativity (LDN)component at Fz compared with the control group. After rTMS treatment, tinnitus patients showed increased N1 response to deviant stimuli and larger MMN and LDN compared with pre-treatment. The topographic maps for the tinnitus group before rTMS -treatment demonstrated global asymmetry between the left and right cerebral hemispheres with more negative activities in left side and more positive activities in right side. In contrast, the brain topographic maps for patients after rTMS-treatment and controls seem roughly symmetrical. The ERP amplitudes and brain topographic maps in post-treatment patient group showed no significant difference with those in controls. The characterical changes in ERP and brain topographic maps in tinnitus patients maybe related with the electrophysiological mechanism of tinnitus induction and development. It can be used as an objective biomarker for the evaluation of auditory central in subjective tinnitus patients. These findings support the notion that rTMS treatment in tinnitus patients may exert a beneficial effect.

This article (a) discusses the definition of faith-based substance abuse treatment programs, (b) juxtaposes Durkheim's theory regarding religion with treatment process model to highlight key dimensions of faith-based and traditional programs, and (c) presents results from a study of seven programs to identify key program dimensions and to identify differences/similarities between program types. Focus group/Concept Mapping techniques yielded a clear "spiritual activities, beliefs, and rituals" dimension, rated as significantly more important to faith-based programs. Faith-based program staff also rated "structure and discipline" as more important and "work readiness" as less important. No differences were found for "group activities/cohesion" and "role modeling/mentoring," "safe, supportive environment," and "traditional treatment modalities." Programs showed substantial similarities with regard to core social processes of treatment such as mentoring, role modeling, and social cohesion. Implications are considered for further research on treatment engagement, retention, and other outcomes.

Provoked vestibulodynia is a highly prevalent condition characterized by acute recurrent pain located at the vaginal entrance in response to pressure application or attempted vaginal penetration. Despite a wide variety of treatments offered to women with provoked vestibulodynia, a high proportion of women are refractory to conventional treatment. Transcranial direct-current stimulation is a noninvasive brain stimulation technique that has been shown effective for improving various chronic pain conditions. Growing evidence suggests that the central nervous system could play a key role in provoked vestibulodynia. Targeting the central nervous system could therefore be a promising treatment for women with provoked vestibulodynia. The purpose of this study was to evaluate and compare the efficacy of active and sham transcranial direct-current stimulation in reducing pain intensity during intercourse in patients with provoked vestibulodynia. We conducted a triple-blind, parallel-group, randomized controlled trial. Women aged 17-45 years diagnosed with provoked vestibulodynia by a gynecologist using a validated protocol were randomized to 10 sessions of either active transcranial direct-current stimulation (intensity = 2 mA) or 10 sessions of sham transcranial direct-current stimulation, over a 2-week period. Both active and sham transcranial direct-current stimulation were applied for 20 minutes, with the anode positioned over the primary motor cortex, and the cathode over the contralateral supraorbital area. Outcome measures were collected at baseline, 2 weeks after treatment, and at 3-month follow-up by an evaluator blinded to group assignment. The primary objective was to assess pain intensity during intercourse, using a numerical rating scale. Secondary outcomes focused on sexual function and distress, vestibular sensitivity, psychological distress, treatment satisfaction, and patient impression of change. Statistical analyses were conducted on the intention-to-treat basis, and treatment effects were evaluated using a mixed linear model for repeated measures. A total of 40 patients were randomly assigned to receive either active (n = 20) or sham (n = 20) transcranial direct-current stimulation treatments from November 2014 through February 2016. Baseline characteristics were similar between the active and sham transcranial direct-current stimulation groups. In full compliance with the study protocol, every participant followed all courses of the study treatment, including assessments at 2-week and 3-month follow-up. Pain during sexual intercourse was not significantly different between active and sham treatment groups 2 weeks after treatment (P = .84) and at follow-up (P = .09). Mean baseline and 2-week assessment pain intensity were, respectively, 6.8 (95% confidence interval, 5.9-7.7) and 5.6 (95% confidence interval, 4.7-6.5) for active transcranial direct-current stimulation (P = .03) vs 7.5 (95% confidence interval, 6.6-8.4) and 5.7 (95% confidence interval, 4.8-6.6) for sham transcranial direct-current stimulation (P = .001). Nonsignificant differences between the 2 groups were also found in their sexual function and distress after treatment (P > .20) and at follow-up (P > .10). Overall, at 2-week assessment 68% assigned to active transcranial direct-current stimulation reported being very much, much, or slightly improved compared to 65% assigned to sham transcranial direct-current stimulation (P = .82), and still comparable at follow-up: 42% vs 65%, respectively (P = .15). Findings suggest that active transcranial direct-current stimulation is not more effective than sham transcranial direct-current stimulation for reducing pain in women with provoked vestibulodynia. Likewise, no significant effects were found on sexual function, vestibular sensitivity, or psychological distress. Copyright © 2017 Elsevier Inc. All rights reserved.

The aim of this study was to determine whether beta-carotene administration reduces oxidative stress and influences antioxidant, mainly glutathione-related, defense systems in workers chronically exposed to lead. The population consisted of two randomly divided groups of healthy male volunteers exposed to lead. Workers in the first group (reference group) were not administered any antioxidants, while workers in the second group (CAR group) were treated orally with 10 mg of beta-carotene once a day for 12 weeks. Biochemical analysis included measuring markers of lead-exposure and oxidative stress in addition to the levels and activities of selected antioxidants. After treatment, levels ofmore » malondialdehyde, lipid hydroperoxides and lipofuscin significantly decreased compared with the reference group. However, the level of glutathione significantly increased compared with the baseline. Treatment with beta-carotene also resulted in significantly decreased glutathione peroxidase activity compared with the reference group, while the activities of other glutathione-related enzymes and of superoxide dismutase were not significantly changed. However, the activities of glucose-6-phosphate dehydrogenase and catalase, as well as the level of alpha-tocopherol, were significantly higher after treatment compared with the baseline. Despite controversy over the antioxidant properties of beta-carotene in vivo, our findings showed reduced oxidative stress after beta-carotene supplementation in chronic lead poisoning. - Highlights: • Beta-carotene reduces oxidative stress in lead-exposed workers. • Beta-carotene elevates glutathione level in lead-exposed workers. • Beta-carotene administration could be beneficial in lead poisoning.« less

The rapid economic development in the Arabian Gulf has resulted in lifestyle changes that have increased the prevalence of obesity and type 2 diabetes, with the greatest increases observed in Kuwait. Dyslipidemia and diabetes are risk factors for disruptions in cortical neurotransmitter homeostasis. This study investigated the effect of the antidiabetic medications canagliflozin (CAN) and metformin (MET) on the levels of cortical neurotransmitters in a diabetic rat model. The rats were assigned to the control (C) group, the diabetic group that did not receive treatment (D) or the diabetic group treated with either CAN (10 mg/kg) or MET (100 mg/kg) for 2 or 4 weeks. Blood and urine glucose levels and cortical acetylcholinesterase (AChE) activity were assayed, and amino acid and monoamine levels were measured using HPLC. The diabetic group exhibited a significant increase in AChE activity and a decrease in monoamine and amino acid neurotransmitter levels. In the CAN group, AChE was significantly lower than that in the D and D + MET groups after 2 weeks of treatment. In addition, a significant increase in some cortical monoamines and amino acids was observed in the D + MET and D + CAN groups compared with the D group. Histopathological analysis revealed the presence of severe focal hemorrhage, neuronal degeneration, and cerebral blood vessel congestion, with gliosis in the cerebrum of rats in the D group. The CAN-treated group exhibited severe cerebral blood vessel congestion after 2 weeks of treatment and focal gliosis in the cerebrum after 4 weeks of treatment. Focal gliosis in the cerebrum of rats in the MET-treated group was observed after 2 and 4 weeks of treatment. We conclude that the effect of CAN and MET on neurotransmitters is potentially mediated by their antihyperglycemic and antihyperlipidemic effects. In addition, the effects of CAN on neurotransmitters might be associated with its receptor activity, and the effect of MET on neurotransmitters might be associated with cerebral metabolism.

Migraine is a complex nervous system disease characterized by typical throbbing and unilateral headache, which causes severe healthy and social issues worldwide. The purpose of this study was to investigate the effect of baicalein (BAI) on the treatment of migraine. Twenty-four rats were randomly divided equally into four groups, including a blank group, model group, positive group (ibuprofen tablets 82mg/kg), and BAI group (60mg/kg). All rats were intragastrically treated with the corresponding treatment for 10 consecutive days, and they were subcutaneously injected with NTG (10mg/kg) 1h after the last treatment, except in the blank group. After model establishment, the behaviors of all rats, including scratching head and shaking body were observed continuously for 100min. Four hours after NTG treatment, all rats were anaesthetized and the blood was collected. Thereafter, nitric oxide (NO) in plasma was determined by colorimetric method, the level of calcitonin gene-related peptide (CGRP) and endothelin (ET) were detected by radioimmunoassay method. In addition, immunohistochemistry was applied to detect c-Fos neuronal activity in trigeminal nucleus caudalis (TNC). Behavioral research showed that BAI administration alleviated the hyperalgesia in migraine rats. Compared with the model group, the levels of NO and CGRP in BAI administration groups were markedly decreased (p<0.01), and the levels of ET was significantly increased (p<0.01). Meanwhile, immunohistochemistry results showed that NTG treatment significantly activated c-Fos neurons while BAI treatment inhibited the expression of c-Fos. BAI could alleviate the migraine-like headache induced by NTG, which is related to the regulation of vasoactive substances. These findings may contribute to the further study of BAI as a potential drug for migraine pharmacotherapy. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The main objective of this study was to prove that a postoperative combined continuous passive motion (CPM) and physiotherapy treatment protocol (CPM group) can achieve 90 degrees active abduction in the shoulder joint earlier than physiotherapy alone (PT group). The indication was a complete tear of the rotator cuff. The study was conducted under in-patient and out-patient conditions. 55 patients were included in this study. The prospective, randomized multicenter study design complies with DIN EN 540. The primary endpoint was the time span until 90 degrees active abduction was achieved by the patients. Patients in the CPM group reached the primary endpoint on average 12 days earlier than the control group. This difference was statistically significant (p = 0.0292). Analyzing the secondary endpoints, e. g., pain and disablement, the results in the CPM group showed again advantages of the combined treatment protocol (CPM + physiotherapy). The postoperative treatment of a total tear of the rotator cuff with a combined continuous passive motion and physiotherapy protocol provided a significantly earlier range of motion in the shoulder joint than physiotherapy alone. There was no report of CPM-related adverse effects.

Protocatechuic acid-grafted-chitosan (PA-g-CS) solution with antioxidant activity was developed as a novel edible coating material for Pleurotus eryngii postharvest storage. The effect of PA-g-CS coating on the postharvest quality of P. eryngii was investigated by determination of various physicochemical parameters and enzyme activities. Results showed that the antioxidant capacity and viscosity of PA-g-CS solutions were closely related to the grafting degree and were much higher than that of chitosan (CS) solution. At the end of 15 days of storage, serious mushroom browning was observed in the control and CS coating groups. By contrast, PA-g-CS coating groups with medium and high grafting degrees maintained better physical appearance. Among all of the treatment groups, P. eryngii in PA-g-CS III coating group exhibited the highest firmness and the lowest weight loss, browning degree, respiration rate, malondialdehyde content, electrolyte leakage rate, superoxide anion production rate, and hydrogen peroxide content. Moreover, P. eryngii in PA-g-CS III coating group maintained relatively higher antioxidant enzyme activities but lower polyphenol oxidase activity than other treatment groups. Therefore, PA-g-CS III is a promising preservation agent for P. eryngii.

Virtual patients (VPs) have been recently integrated within different learning activities. To compare between the effect of using VPs in a collaborative learning activity and using VPs in an independent learning activity on students' knowledge acquisition, retention and transfer. For two different topics, respectively 82 and 76 dental students participated in teaching, learning and assessment sessions with VPs. Students from a female campus and from a male campus have been randomly assigned to condition (collaborative and independent), yielding four experimental groups. Each group received a lecture followed by a learning session using two VPs per topic. Students were administrated immediate and delayed written tests as well as transfer tests using two VPs to assess their knowledge in diagnosis and treatment. For the treatment items of the immediate and delayed written tests, females outperformed males in the collaborative VP group but not in the independent VP group. On the female campus, the use of VPs in a collaborative learning activity is more effective than its use as an independent learning activity in enhancing students' knowledge acquisition and retention. However, the collaborative use of VPs by itself is not enough to produce consistent results across different groups of students and attention should be given to all the factors that would affect students' interaction.

Curcumin is known to possess potent antiinflammatory and antiarthritic properties. This pilot clinical study evaluated the safety and effectiveness of curcumin alone, and in combination with diclofenac sodium in patients with active rheumatoid arthritis (RA). Forty-five patients diagnosed with RA were randomized into three groups with patients receiving curcumin (500 mg) and diclofenac sodium (50 mg) alone or their combination. The primary endpoints were reduction in Disease Activity Score (DAS) 28. The secondary endpoints included American College of Rheumatology (ACR) criteria for reduction in tenderness and swelling of joint scores. Patients in all three treatment groups showed statistically significant changes in their DAS scores. Interestingly, the curcumin group showed the highest percentage of improvement in overall DAS and ACR scores (ACR 20, 50 and 70) and these scores were significantly better than the patients in the diclofenac sodium group. More importantly, curcumin treatment was found to be safe and did not relate with any adverse events. Our study provides the first evidence for the safety and superiority of curcumin treatment in patients with active RA, and highlights the need for future large-scale trials to validate these findings in patients with RA and other arthritic conditions.

To evaluate the outcome of part-time occlusion therapy with or without near activities in monocular amblyopic patients. One hundred and thirty patients who prescribed daily occlusion therapy (part-time occlusion) were followed-up for a 12-week period. The study was carried out in the Pediatric Ophthalmology and Orthoptics Clinics of King Abdul-Aziz University Hospital, Riyadh, Saudi Arabia for the period from January to November 2010. Sixty-five patients were recommended to undertake the 3 hours of near visual activities (such as reading a book during patching) while the other 65 patients were not advised to do any near activity. Main outcome measures were best corrected visual acuity (VA) for both groups and line improvement. The total line of VA improved from baseline by an average of 6.7+/-2.37 line log MAR (logarithm of the minimum angle of resolution) units in the group of patching with near activities and by an average of 5.3+/- 2.04 line log MAR units in the group of patching without near activities. All type of amblyopia (strabismic, anisometropic, and mixed types of amblyopia) improved significantly after patching with near activities. Both moderate and severe amblyopia improved significantly in the group of near activities compared with the group without near activities. Performing near activities while patching in the treatment of anisometropic, stabismic, or combined amblyopia improves the VA outcome more than patching alone.

The purpose of this study was to evaluate probable protective effects of resveratrol treatment on hepatic oxidative events in a rat model of metabolic syndrome (MetS). Thirty-two male adult rats were randomly divided into 4 groups: control, fructose, resveratrol, and fructose plus resveratrol. To induce MetS, fructose solution (20 % in drinking water) was used. Resveratrol (10 mg/kg/day) was given by oral gavage. All treatments were given for 8 weeks. Serum lipid profile, glucose and insulin levels, liver total oxidant status (TOS) levels and paraoxonase (PON), glutathione peroxidase (GPx), superoxide dismutase (SOD) and catalase (CAT) activities were analyzed. Fructose-fed rats displayed statistically significant increases in TOS levels, and decreases in PON activity compared to the control group. Resveratrol treatment moderately prevented the decrease in liver PON activity caused by fructose. On the other hand, resveratrol, alone or in combination with fructose, did not change the TOS levels when compared to the fructose group. The SOD and CAT activities in all groups did not change. In this experimental design, high-fructose consumption led to elevated TOS levels and low PON activities. The resveratrol therapy shown beneficial effects on PON activity. However, it was found to behave like a prooxidant when administered together with fructose and alone in some parameters. Our results can inspire the development of new clinical therapy in patients with MetS (Tab. 2, Ref. 34).

Background Planter fasciitis is a common cause of heel pain in adults. Many treatment options exist. Most of patients resolve with conservative management. Approximately 10% of patients develop persistent and often disabling symptoms. Patients and methods This prospective study includes 37 patients with an established diagnosis of chronic plantar fasciitis, aiming to compare two different techniques of treatment. First group includes 17 patients with a mean age of 42 years treated by endoscopic plantar fasciotomy (EPF); the mean follow-up was 11 months. Second group includes 20 patients with a mean age of 45 years treated by extracorporeal shock Wave Therapy (ESWT); the mean follow-up was 7.6 months. Results In the first group (EPF), using the visual analog scale the average post-operative pain was improved from 9.1 to 1.6. Post-operatively, 58.8% had no limitation of functional activities, 35.3% had minimal limitation of activities and 5.9% had moderate limitation of activities. Concerning patient satisfaction, 82.3% of patients were completely satisfied, 11.8% of patients were satisfied with reservation and 5.9% of patients were unsatisfied. For the second group (ESWT), using the visual analog scale the average post-operative pain was improved from 9 to 2.1. Post-operatively, 50% had no functional limitation of activities, 35% had minimal limitation of activities, 10% had moderate limitation of activities, and 5% had severe limitation of activities. Concerning patient satisfaction, 75% of patients were completely satisfied and 25% were satisfied with reservation or unsatisfied. Conclusion Because of better results with endoscopic release versus the benefits of no complications, no immobilization, and early resumption of full activities with ESWT, we conclude that ESWT is a reasonable earlier line of treatment of chronic plantar fasciitis before EPF.

Polydeoxyribonucleotide improves wound healing of fractional laser resurfacing in rat model.

PubMed

Yu, Mi; Lee, Jun Young

2017-02-01

Polydeoxyribonucleotide (PDRN) is an active compound that can promote wound healing. PDRN stimulates wound healing by enhancing angiogenesis and increasing fibroblast growth rates. Laser skin resurfacing is a popular cosmetic procedure for skin rejuvenation. Despite excellent improvement of photo-damaged skin and acne scarring, it is accompanied with drawbacks, such as prolonged erythema and crusting. This study was designed to assess the effect of PDRN on wounds induced by fractional laser resurfacing. Twelve male rats aged 8 weeks were randomly assigned to the PDRN treatment group and the control group. Wounds were induced using a fractional ablative CO 2 laser. The treatment group received daily injections of PDRN and the control group received injections of the vehicle. Wound healing assessed by clinical features and histopathologic findings. The process of wound healing was faster in the treatment group than in the control group. In the histopathological examination, the granulation tissue thickness score of the treatment group was significantly higher than that of the control group. Results of immunohistochemical staining showed a marked increase of VEGF-positive cells and PECAM-1/CD31-positive microvessels in the treatment group. PDRN may be a beneficial option to promote wound healing after laser treatment.

To explore the optimized rehabilitation program in the treatment of post-stroke hemiplegia at the recovery stage. Based on the randomized controlled principle, 60 patients were randomized into an rehabilita tion + massage group (group A) and an rehabilitation + acupuncture group (group B), 30 cases in each one. Bobath sport therapy and functional training were adopted in the two groups. In the group A, the massage therapy was added. The rolling method and palm-rubbing method were used on the affected side, the pressing, kneading and plucking methods were applied to Jianliao (LI 15), Jianzhen (SI 9), Quchi (LI 11), Huantiao (GB 30), Weizhong (BL 40), Chengshan (BL 57), Zusanli (ST 36) and the other acu points; and the nipping method was adopted at the twelve Jing-well points. In the group B, acupuncture was applied to Baihui (BL 20), Jianliao (LI 15), Quchi (LI 11), Shousanli (LI 10), Huantiao (GB 30), Yanglingquan (GB 34), Jiexi (ST 41) and the other acupoints. The treatment was given once a day, 5 treatments a week in the two groups. The efficacy was evaluated in 3 weeks. Fugl-Meyer scale, Barthel index (BI) score, modified Rankin scale and stroke-specific quality of life (SS-QOL) were used to assess the limb motor function, the activity of daily life (ADL), independent activity of life and the quality of life of the patients in the two groups before and after treatment. Based on the total cost and benefit, the health economics evaluation was conducted in the patients of the two groups. The treatments all improved the limb motor function (group A: 26.00 (22) vs 37.00 (33); group B: 30.50 (21) vs 39.50 (36)), the independent activity of life, ADL (group A: 43.50 +/- 22.25 vs 57.50 +/- 22.25; group B: 52.83 +/- 16.59 vs 66.67 +/- 12.82) and the quality of life (group A: 122.23 +/- 30.00 vs 145.50 +/- 28.14; group B: 132.43 +/- 23.87 vs 151.47 +/- 22.37) in the patients of the two groups. The differences in all the indices were significant statistically before and after treatment in the two groups (all P<0.05). Above indices after treatment were not different obviously between the two groups (all P>0.05). In terms of health economics, the expense was decreased by RMB 688.48 while BI was increased by every 5 score in group A in comparison with the group B. Both the rehabilitation and massage therapy and the rehabilitation and acupuncture therapy improve the limb motor function and the quality of life in the patients of post-stroke hemiplegia. The therapeutic efficacies are similar between the two therapeutic programs. The program of rehabilitation and massage is more economical in the aspects of ADL improvement, being advantageous at simple operation and low cost.

A meeting was convened by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis (GRAPPA) and Outcome Measures in Rheumatology (OMERACT) to further the development of consensus among physicians and patients regarding composite disease activity measures and targets in psoriatic arthritis (PsA). Prior to the meeting, physicians and patients completed surveys on outcome measures. A consensus meeting of 26 rheumatologists, dermatologists, and patient research partners reviewed evidence on composite measures and potential treatment targets plus results of the surveys. The meeting consisted of plenary presentations, breakout sessions, and group discussions. International experts including members of GRAPPA and OMERACT were invited to the meeting, including the developers of all of the measures discussed. After discussions, participants voted on proposals for use, and consensus was established in a second survey. Survey results from 128 health care professionals and 139 patients were analyzed alongside a systematic literature review summarizing evidence. A weighted vote was cast for composite measures. For randomized controlled trials, the most popular measures were the PsA disease activity score (40 votes) and the GRAPPA composite index (28 votes). For clinical practice, the most popular measures were an average of scores on 3 visual analog scales (45 votes) and the disease activity in PsA score (26 votes). After discussion, there was no consensus on a composite measure. The group agreed that several composite measures could be used and that future studies should allow further validation and comparison. The group unanimously agreed that remission should be the ideal target, with minimal disease activity (MDA)/low disease activity as a feasible alternative. The target should include assessment of musculoskeletal disease, skin disease, and health-related quality of life. The group recommended a treatment target of very low disease activity (VLDA) or MDA. Consensus was not reached on a continuous measure of disease activity. In the interim, the group recommended several composites. Consensus was reached on a treatment target of VLDA/MDA. An extensive research agenda was composed and recommends that data on all PsA clinical domains be collected in ongoing studies. © 2017, American College of Rheumatology.

Objectives To conduct a kinematic comparison of occupational posture in orthodontists and dentists in their workplace. Design Observational study. Setting Dentist surgeries and departments of orthodontics at university medical centres in Germany. Participants A representative sample of 21 (10 female, 11 male) dentists (group G1) and 21 (13 female, 8 male) orthodontists (G2) with one male dropout in G2. Outcome measures The CUELA (computer-assisted acquisition and long-term analysis of musculoskeletal loads) system was used to analyse occupational posture. Parallel to the recording through the CUELA system, a software-supported analysis of the activities performed (I: treatment; II: office; III: other activities) was carried out. In line with ergonomic standards the measured body angles are categorised into neutral, moderate and awkward postures. Activities between the aforementioned groups are compared using the stratified van Elteren U test and the Wilcoxon–Mann–Whitney U test. All p values are subject to the Bonferroni–Holm correction. The level of significance is set at 5%. Results The percentage of time spent on activities in categories I–II–III was as follows: dentists 41%–23%–36% and orthodontists 28%–37%–35%. The posture analysis of both groups showed, for all percentiles (P5–95), angle values primarily in the neutral or moderate range. However, depending on the activity performed, between 5% and 25% of working hours were spent in unfavourable postures, especially in the head-and-neck area. Orthodontists have a greater tendency than dentists to perform treatment activities with the head and torso in unfavourable positions. The statistically significant differences between the two groups with regard to the duration and the relevance of the activities performed confirm this assumption for all three categories (p<0.01, p<0.05). Conclusions Generally, both groups perform treatment activities in postures that are in the neutral or medium range; however, dentists had slightly more unfavourable postures during treatment for a greater share of their work day.

2015-01-01

The ability of ferrous chelates including hairtail protein hydrolysates to prevent and reduce fatigue was studied in rats. After hydrolysis of hairtail surimi with papain, the hairtail protein hydrolysates (HPH) were separated into three groups by range of relative molecular weight using ultrafiltration membrane separation. Hairtail proteins were then chelated with ferrous ions, and the antioxidant activity, the amino acid composition and chelation rate of the three kinds of ferrous chelates including hairtail protein hydrolysates (Fe-HPH) were determined. Among the three groups, the Fe-HPH chelate showing the best conditions was selected for the anti-fatigue animal experiment. For it, experimental rats were randomly divided into seven groups. Group A was designated as the negative control group given distilled water. Group B, the positive control group, was given glutathione. Groups C, D and E were designated as the Fe-HPH chelate treatment groups and given low, medium, and high doses, respectively. Group F was designated as HPH hydrolysate treatment group, and Group G was designated as FeCl2 treatment group. The different diets were orally administered to rats for 20 days. After that time, rats were subjected to forced swimming training after 1 h of gavage. Rats given Fe-FPH chelate had higher haemoglobin regeneration efficiency (HRE), longer exhaustive swimming time and higher SOD activity. Additionally, Fe-FPH chelate was found to significantly decrease the malondialdehyde content, visibly enhance the GSH-Px activity in liver and reduce blood lactic acid of rats. Fe-HPH chelate revealed an anti-fatigue effect, similar to or better than the positive control substance and superior to HPH or Fe when provided alone. PMID:26633476

High-dose (4.0 g/day) mesalazine is typically used for induction therapy, but its efficacy as maintenance therapy remains to be determined. We conducted a multicenter retrospective study to investigate the efficacy of continuous treatment with 4.0 g/day of mesalazine. Japanese ulcerative colitis (UC) patients receiving acute induction therapy with 4.0 g/day mesalazine were enrolled and followed. Those who clinically improved or who achieved clinical remission were categorized into 2 sub-groups according to the median duration of treatment with 4.0 g/day of mesalazine. The clinical relapse frequency and the time to relapse were analyzed. We enrolled 180 patients with active UC, and then 115 patients who clinically improved or who achieved clinical remission after treatment with 4.0 g/day mesalazine were categorized into 2 sub-groups according to the median of treatment duration: a short-term treatment group (≤105 days, n=58) and a long-term treatment group (>105 days, n=57). Overall, 45 (39.1%) patients relapsed: 28 (48.3%) in the short-term treatment group and 17 (29.8%) in the long-term treatment group. This difference was statistically significant (p<0.05). The relapse-free rate in the long-term treatment group was significantly higher than that in the short-term treatment group (p<0.05). The mean time to relapse in the long-term treatment group was significantly longer than that in the short-term treatment group (425.6±243.8 days vs. 277.4±224.5 days; p<0.05). Long-term continuous treatment with high-dose mesalazine (4.0 g/day) may be more effective than short-term treatment for maintenance of remission in UC patients.

Objective To compare the clinical efficacy of two techniques for fabricating a Bimler device by assessing the patient's surface electromyography (sEMG) activity at rest before treatment and six months after treatment. Methods Twenty-four patients undergoing orthodontic treatment were enrolled in the study; 12 formed the test group and wore a Bimler device fabricated with a Myoprint impression using neuromuscular orthodontic technique and 12 formed the control group and were treated by traditional orthodontic technique with a wax bite in protrusion. The "rest" sEMG of each patient was recorded prior to treatment and six months after treatment. Results The neuromuscular-designed Bimler device was more comfortable and provided better treatment results than the traditional Bimler device. Conclusion This study suggests that the patient group subjected to neuromuscular orthodontic treatment had a treatment outcome with more relaxed masticatory muscles and better function versus the traditional orthodontic treatment.

Members of Cyathostominae are pervasive parasites of equids that can cause larval cyathostominosis, a potentially life-threatening disease that occurs when a multitude of encysted larvae synchronously excyst from the wall of the large intestine. Moxidectin and fenbendazole are the two current labeled drugs that target the encysted larval stages; however, there is limited knowledge of the local inflammatory response to the larvae and to the two treatments in clinically healthy horses. This study is the first to evaluate the local inflammatory response to cyathostomin larvae and to larvicidal treatment at 2 and 5 weeks post treatment. Thirty-six ponies with naturally acquired cyathostomin infections were randomly allocated into 3 groups: Group 1, fenbendazole at 10 mg/kg for 5 days, Group 2, a single dose of moxidectin at 0.4 mg/kg, and Group 3, untreated controls. Tissue samples from the cecum and dorsal and ventral colons were used for histopathological and immunohistochemical evaluation. Tissues were stained with routine hematoxylin and eosin (H&E) for light microscopy and immunohistochemically for MAC387, CD20, and CD3 for differentiation of activated macrophages, B cells, and T cells, respectively. Semiquantitative scores were assigned for all inflammatory cell types and fibrous connective tissue. Larvae observed by light microscopy were enumerated and classified by stage. Mucosal ulcerations and submucosal granulomas were also enumerated. Mean macrophage scores were higher in the moxidectin group than the fenbendazole group (p = 0.0185) and the control group had a higher activated macrophage score than both treatment groups (p = 0.0104, p = 0.0004). T lymphocyte scores were higher in the moxidectin group when compared to the control group (p = 0.0069). Goblet cell hyperplasia scores were elevated at 5 weeks post treatment compared to 2 weeks post treatment (p = 0.0047) and were elevated in the ventral colon compared to the dorsal colon (p = 0.0301). Eosinophil scores were elevated surrounding degenerative larvae when compared to intact larvae (p = 0.0001). Mucosal ulcerations were found only in the control group at 2 weeks post treatment. This study found subtle inflammatory differences between treatment groups but provided new information about goblet cells and eosinophils in relation to encysted cyathostomin larvae.

Background: Painful neuropathy is a very common complication in diabetic patients. Various treatment strategies like manual therapies, conservative management, drug therapy and exercise have been opted for this problem. Studies have shown clinical effectiveness of laser acupuncture as well. On the other hand, Amitryptaline is also a commonly used treatment for this disease. We aim to compare the efficacy of both treatments. Objective: To assess the effect of laser acupuncture in patients suffering from painful diabetic neuropathy and its comparison with standard of care. Patients and Method: This study was conducted in Diabetic and Endocrine Management Center (DEMC) Lahore General Hospital, Lahore, Pakistan. A randomized control trial (RCT) was opted and a total of 164 patients were chosen using Non-probability purposive sampling technique. Pain was graded by using a patient friendly Visual Analogue Score (VAS), scoring from 0 to 10. Treatment was done involving organized fortnightly follow ups. Data of all patients was recorded on Performa and was entered and analyzed for descriptive statistics in PASW 18 (IBM®. SPSS). Results: A total of 164 subjects were included in the study who were subdivided into three groups labeled as A, B and C for laser therapy treatment, amitryptaline treatment and controls respectively. The mean age of subjects was 51.54+/-10.46 in Group A, 49.38+/-10.56 in Group B and 51.70+/-11.43 in Group C. The difference of mean ages in all study groups was statistically insignificant (p-value= 0.469). The average pain score in patients who received laser therapy was 5.95+/-0.91 before treatment, whereas after treatment it was 4.31+/-0.98. The mean pain score in subjects having Amitryptaline before starting the treatment was 6.87+/-0.71 and after treatment, it was 6.23+/-0.98. The mean score for daily life activities in subjects who received laser therapy was 9.562.37 before treatment, while after treatment it was 7.56+/-1.54. The average score for daily life activities in patients having Amitryptaline before starting the treatment was 9.05+/-1.93 and after treatment, it was 8.11+/-1.71. Average depression and anxiety score in patients receiving laser therapy was 9.29+/-2.28 before treatment, whereas after treatment it was found to be 7.42+/-1.91. Similarly, the mean depression and anxiety score in patients of Amitryptaline group before starting the treatment was 9.38+/-2.21 and after treatment, it was 8.38+/-2.14. Conclusion: The mean score in our study reveals that laser therapy shows better outcomes in improvement of pain relief, depression, anxiety and daily life activities compared to amitryptaline in patients of diabetic neuropathy.

The tuberculin skin test (TST) is the standard tool to diagnose latent tuberculosis infection (LTBI) in mass screening. The aim of this study is to find an optimal cut-off point of the TST+ rate within tuberculosis (TB) contacts to predict the active TB development among adolescents in school TB outbreaks. The Korean National Health Insurance Review and Assessment database was used to identify active TB development in relation to the initial TST (cut-off, 10 mm). The 7,475 contacts in 89 schools were divided into two groups: Incident TB group (43 schools) and no incident TB group (46 schools). LTBI treatment was initiated in 607 of the 1,761 TST+ contacts. The association with active TB progression was examined at different cut-off points of the TST+ rate. The mean duration of follow-up was 3.9±0.9 years. Thirty-three contacts developed active TB during the 4,504 person-years among the TST+ contacts without LTBI treatment (n=1,154). The average TST+ rate for the incident TB group (n=43) and no incident TB group (n=46) were 31.0% and 15.5%, respectively. The TST+ rate per group was related with TB progression (odds ratio [OR], 1.025; 95% confidence interval [CI], 1.001-1.050; p=0.037). Based on the TST+ rate per group, active TB was best predicted at TST+ ≥ 16% (OR, 3.11; 95% CI, 1.29-7.51; area under curve, 0.64). Sixteen percent of the TST+ rate per group within the same grade students can be suggested as an optimal cut-off to predict active TB development in middle and high schools TB outbreaks.

Self-report studies indicate that cannabis could increase sexual desire in some users. We hypothesized that intoxication increases activation of brain areas responsive to visual erotica, which could be useful in the treatment of hypoactive sexual desire disorder, a condition marked by a lack of sexual desire. The aim of this study is to assess the aphrodisiacal properties of cannabis. We conducted an open-randomized study with 21 heterosexual casual cannabis users. A 3T MRI was used to measure brain activation in response to erotic pictures. Blood samples were collected to determine the serum levels of cannabinoids, cortisol and prolactin. Participants were grouped according to whether they had ever experienced any aphrodisiacal effects during intoxication (Group A) or not (Group non-A). Intoxication was found to significantly increase activation in the right nucleus accumbens in the Group A while significantly decreasing activation in the Group non-A. There was also a significant interaction between the group and intoxication, with elevated prolactin in the Group non-A during intoxication. No intoxication-related differences in subjective picture evaluations were found. Cannabis intoxication increases activation of the right nucleus accumbens to erotic stimuli. This effect is limited to users whose prolactin is not elevated in response to intoxication. This effect may be useful in the treatment of low sexual desire.

Aging is characterized by gradual accumulation of macromolecular damage leading to progressive loss of physiological function and increased susceptibility to diverse diseases. Effective anti-aging strategies involving caloric restriction or antioxidant supplementation are receiving growing attention to attenuate macromolecular damage in age associated pathology. In the present study, we for the first time investigated the effect of quercetin, caloric restriction and combined treatment (caloric restriction with quercetin) on oxidative stress parameters, acetylcholinesterase and ATPases enzyme activities in the cerebral cortex of aged male Wistar rats. 21 months aged rats were divided into four groups (n=6-8) such as group 1-fed ad libitum (AL); group 2-quercetin supplementation of 50 mg/kg b.w/day for 45 days fed ad libitum (QUER); group 3: caloric restricted (CR) (fed 40% reduced AL for 45 days); group 4-fed 40% CR and 50 mg/kg b.w/day QUER for 45 days (CR + QUER). Group 5-three month age old rats served as young control (YOUNG). Our results demonstrate that combined treatment of caloric restriction and quercetin significantly improved the age associated decline in the activities of endogenous antioxidant enzymes [such as superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx)] and glutathione (GSH) content and attenuated elevated levels of protein carbonyl content (PCC), lipid peroxidation, lipofuscin, reactive oxygen species (ROS), and nitric oxide (NO). Furthermore, it is also observed that combined treatment ameliorated age associated alterations in acetylcholine esterase (AChE) and adenosine triphosphatases (ATPases) such as Na+/K+-ATPase and Ca+2-ATPase (but not Mg+2- ATPase) enzyme activities. Finally, we conclude that combined treatment of caloric restriction and quercetin (but not either treatment alone) in late life is an effective anti-aging therapy to counteract the age related accumulation of oxidative macromolecular damage.

In diabetes, impaired wound healing and other tissue abnormalities are considered major concerns. The aim of the present study was to assess the wound-healing activity of methanolic extracts of the extract of Lycium depressum leaves. A total of 60 healthy male Wistar diabetic rats weighing approximately 160 to 180 g and 7 weeks of age were randomized into 10 groups for incision and excision wound models: sham surgery group (SHAM), including creation of wounds and no treatment; base formulation group (FG) with creation of wounds and application of base formulation ointment; treatment group 1 (TG1) with 1 g of powder extract of the plant material in ointment; treatment group 2 (TG2) with 2 g; and treatment group 4 (TG3) with 4 g of powder extract of the plant material in ointment. A wound was induced by an excision- and incision-based wound model in male rats. The mature green leaves of L depressum were collected and authenticated. Extractions of dried leaves were carried out. For wound-healing activity, the extracts were applied topically in the form of ointment and compared with control groups. The healing of the wound was assessed based on excision, incision, hydroxyproline estimation, and biomechanical and biochemical studies. The extract of L depressum leaves enhanced wound contraction, decreased epithelialization time, increased hydroxyproline content, and improved mechanical indices and histological characteristics in treatment groups compared with SHAM and FG ( P < .05). These findings permit the conclusion the extract of L depressum benefits parameters of wound healing in a diabetes induced model.

Low level laser (light) therapy (LLLT) has been demonstrated to promote hair growth in males. A double-blind randomized controlled trial was undertaken to define the safety and physiologic effects of LLLT on females with androgenic alopecia. Forty-seven females (18-60 years old, Fitzpatrick I-IV, and Ludwig-Savin Baldness Scale I-2, I-3, I-4, II-1, II-2 baldness patterns) were recruited. A transition zone scalp site was selected; hairs were trimmed to 3 mm height; the area was tattooed and photographed. The active group received a "TOPHAT655" unit containing 21, 5 mW diode lasers (655 ± 5 nm) and 30 LEDS (655 ± 20 nm), in a bicycle-helmet like apparatus. The placebo group unit appeared identical, containing incandescent red lights. Patients treated at home every other day × 16 weeks (60 treatments, 67 J/cm(2) irradiance/25 minute treatment, 2.9 J dose), with follow up and photography at 16 weeks. A masked 2.85 cm(2) photographic area was evaluated by another blinded investigator. The primary endpoint was the percent increase in hair counts from baseline. Forty-two patients completed the study (24 active, 18 sham). No adverse events or side effects were reported. Baseline hair counts were 228.2 ± 133.4 (N = 18) in the sham and 209.6 ± 118.5 (N = 24) in the active group (P = 0.642). Post Treatment hair counts were 252.1 ± 143.3 (N = 18) in the sham group and 309.9 ± 166.6 (N = 24) in the active group (P = 0.235). The change in hair counts over baseline was 23.9 ± 30.1 (N = 18) in the sham group and 100.3 ± 53.4 (N = 24) in the active group (P < 0.0001). The percent hair increase over the duration of the study was 11.05 ± 48.30 (N = 18) for the sham group and 48.07 ± 17.61 (N = 24) for the active group (P < 0.001). This demonstrates a 37% increase in hair growth in the active treatment group as compared to the placebo group. LLLT of the scalp at 655 nm significantly improved hair counts in women with androgenetic alopecia at a rate similar to that observed in males using the same parameters. © 2014 The Authors.

Doxycycline is an antibiotic agent that inhibits the activity of matrix metalloproteinases (MMPs) present in the extracellular matrix. In this study, the rat incisor was submitted to a hypofunctional condition, and the effects of doxycycline (80 mg/kg/d) on the expression and activity of MMP-2, as well as on eruption rate, were determined in the odontogenic region and in the periodontal ligament for 14 d. Rats were distributed into four groups: normofunctional (NF); doxycyline normofunctional (DNF); hypofunctional (HP); and doxycyline hypofunctional (DHP). The left lower incisors of 10 rats were shortened every 2 d, using a high-rotation drill, to produce the HP and DHP groups, after starting doxycycline treatment (80 mg/kg) by gavage. Eruption was measured using a millimeter ocular, from the gingival margin to the top of the tooth in the HP and DHP groups, and also by a mark made in the tooth previously, in the NF and DNF groups. The hemimandibles were removed and the teeth were extracted to collect the periodontal and odontogenic tissues for immunohistochemical analyses and zymography. The eruption rates were higher in the HP and the DHP groups than in the NF and DNF groups, respectively (p < 0.05). In the odontogenic region, neither of the treatments changed the expression and activity of MMP-2. In the HP group, the shortening treatment decreased the expression, but not the activity, of MMP-2, while doxycycline was able to inhibit the increase of expression and activity of MMP-2. We conclude that the inhibition of MMP-2 by doxycycline, during incisor shortening, was not enough to alter the eruption rate, which suggests that MMP-2 may have an important role in the turnover of extracellular matrix of the periodontal ligament during the tooth-eruption process. © 2016 John Wiley & Sons A/S.

This study examined the effects of text message content (generic vs. culturally tailored) on the login rate of an Internet physical activity program in Hong Kong Chinese adolescent school children. A convenience sample of 252 Hong Kong secondary school adolescents (51% female, 49% male; M age = 13.17 years, SD = 1.28 years) were assigned to one of 3 treatments for 8 weeks. The control group consisted of an Internet physical activity program. The Internet plus generic text message group consisted of the same Internet physical activity program and included daily generic text messages. The Internet plus culturally tailored text message group consisted of the Internet physical activity program and included daily culturally tailored text messages. Zero-inflated Poisson mixed models showed that the overall effect of the treatment group on the login rates varied significantly across individuals. The login rates over time were significantly higher in the Internet plus culturally tailored text message group than the control group (β = 46.06, 95% CI 13.60, 156.02; p = .002) and the Internet plus generic text message group (β = 15.80, 95% CI 4.81, 51.9; p = .021) after adjusting for covariates. These findings suggest that culturally tailored text messages may be more advantageous than generic text messages on improving adolescents' website login rate, but effects varied significantly across individuals. Our results support the inclusion of culturally tailored messaging in future online physical activity interventions.

[Purpose] Problems involving the temporomandibular joint and associated structures can lead to temporomandibular disorder (TMD). The aim of the present study was to evaluate muscle activity in individuals with a diagnosis of TMD before and after treatment with low-level laser therapy (LLLT) through the use of electromyography (EMG). [Subjects and Methods] Male and female individuals aged 14 to 23 years were evaluated. TMD was determined by a clinical examination and the administration of the Research Diagnostic Criteria for Temporomandibular Disorders, followed by the evaluation of sensitivity to palpation of the masseter and anterior temporal muscles as well as the EMG determination of muscle activity. The participants were randomly allocated to an active LLLT group (n=9) and sham group (n=7). Twelve sessions of LLLT were conducted using a wavelength of 780 nm, energy density of 25 J/cm2, power of 50 mW, power density of 1.25 W/cm2 and a 20-second exposure time or sham LLLT. Muscle activity was determined prior to treatment and after the last session. [Results] During the isometric evaluation of the masseter and anterior temporal muscles, an increase in the mean EMG signal was found in the group submitted to active LLLT. When evaluated individually, some participants in the active LLLT group demonstrated a reduction in muscle activity, but no significant differences were found in the mean EMG signal between the initial and final evaluations. [Conclusion] Further studies with a larger sample size are needed to confirm the present findings. PMID:29643585

Aim. This study was performed to evaluate the additional enteral nutrition (EN) in the efficacy of infliximab (IFX) compared with the conventional therapy in managing Crohn's disease (CD) complicated with intestinal fistulas. Methods. A total of 42 CD with intestinal fistulas were randomly divided into infliximab treatment group (n = 20) and conventional therapy group (n = 22). We evaluated the laboratory indexes, Crohn's disease activity index (CDAI), Crohn's disease simplified endoscopic score (SES-CD), and healing of fistula in the two groups before treatment, at 14 weeks, and at 30 weeks, respectively. Results. In the IFX treatment group, the CDAI score, the SES-CD, erythrocyte sedimentation rate, and C-reactive protein levels were significantly decreased during treatment compared with those before treatment. The body mass index and albumin levels were increased in both groups. Moreover, in the IFX treatment group, fistula healing was found in 8 at the 14th week and 18 at the 30th week, respectively, which was greater than that in the conventional therapy group. Conclusion. Our study suggested that infliximab combined with EN is an effective treatment for CD patients complicated with intestinal fistulas. PMID:27738427

Objective: To research the effect of Intravascular low level laser irradiation (ILLLI) on the SOD,MDA in the treatment of psoriasis. Method :47 patients suffering from psoriasis from five groups were treated by Intravascular low level laser irradiation (power:4-5mw,1h per day, period of treatment: 10 days) .We checked the change of SOD,MDA peripheral blood in 10 normal people between pre and post treatment. Group A were treated by He-Ne laser combined with drug, group B were treated by semi-conductor laser combined with drug, group C were treated only by He-Ne laser, group D were treated only by semiconductor laser, group E were treated only by drug . Results: The levels of SOD in red cell of psoriatic patients from five groups after treatment were significantly lower than that of controlled group. The levels of SOD of them were significantly increased and nearly closed to that of controlled group; the levels of MDA in red cell of psoriatic patients from five groups after treatment were significantly higher than that of controlled group; the levels of MDA of them are decreased ,however, they were still not recovered to normal levels. Conclusions: ILLLI, both He-Ne laser and semiconductor laser, can activate SOD in psoriasis patients and enhance their ability of anti-oxidation.

Rifapentine administered 5 days per week has potent activity in mouse models of antituberculosis chemotherapy, but efficacy and safety data are limited in humans. We compared the antimicrobial activity and safety of rifapentine vs rifampin during the first 8 weeks of pulmonary tuberculosis treatment. In total, 531 adults with sputum smear-positive pulmonary tuberculosis were randomized to rifapentine 10 mg/kg/dose or rifampin 10 mg/kg/dose, administered 5 days per week for 8 weeks (intensive phase), with isoniazid, pyrazinamide, and ethambutol. Coprimary outcomes were negative sputum culture on liquid and on solid media at completion of intensive phase. Negative cultures on solid media occurred in 145 of 174 participants (83.3%) in the rifampin group and 171 of 198 participants (86.4%) in the rifapentine group (difference, 3.0%; 95% confidence interval [CI]: -4.3, 10.5); negative cultures in liquid media occurred in 110 of 169 (65.1%) in the rifampin group and 133 of 196 (67.9%) in the rifapentine group (difference, 2.8%; 95% CI: -6.9, 12.4). Among 529 participants who received study therapy, 40 of 254 participants (15.7%) in the rifampin group and 40 of 275 participants (14.5%) in the rifapentine group prematurely discontinued treatment (P=.79). The rifapentine regimen was safe but not significantly more active than a standard rifampin regimen, by the surrogate endpoint of culture status at completion of intensive phase. Assessment of higher exposures to rifapentine for tuberculosis treatment is warranted. NCT00694629.

Background: Low Level Laser Therapy (LLLT) has emerged as a possible treatment modality for tendinopathies. Human studies have investigated LLLT for Achilles Tendinopathy and the effectiveness remains contentious. Purpose: To assess the clinical effectiveness of Low-Level Laser Therapy (LLLT) in the management of Achilles Tendinopathy. Method: Forty patients were randomised into an active laser or placebo group; all patients, therapists and investigator were blinded to allocation. All patients were given an eccentric exercise program and irradiated 3 times per week for 4 weeks with either an active or placebo laser at 6 standardized points over the affected tendons. Irradiation parameters in the active laser group were: 810 nm, 100 mW, applied to 6 points on the tendon for 30 seconds giving a dose of 3 J per point and 18 J per session; power density 100 mW/cm2. Outcome measures were the VISA-A questionnaire and a visual analogue scale of pain. Patients were measured before treatment, at 4 and 12 weeks. ANCOVA was used to analyze data, using the effects of baseline measurements as a covariate. Results: Within groups, there were significant improvements (p<0.05) at 4 and 12 weeks for all outcome measures, except pain for the laser group at 4 weeks (p = 0.13). Between groups differences at both 4 and 12 weeks showed no significant difference between groups (p>0.05). Conclusion: This use of the above parameters demonstrated no added benefit of LLLT over that of eccentric exercise in the treatment of Achilles Tendinopathy.

Biofield treatments have been used for pain control in patients with cancer and chronic pain. However, research on the effect of biofield treatment on specific somatic disorders is lacking. This study intends to investigate the effect of oscillating biofield therapy (OBFT) on symptoms of carpal tunnel syndrome. Randomized, placebo-controlled, double-blind study. Thirty patients with chronic carpal tunnel syndrome participated in the study. Patients were randomly assigned to active or placebo treatment groups. Those in the treatment group received six sessions of OBFT with intention to treat during a period of 2 weeks. Patients in the placebo group had the same number of treatment sessions with mock OBFT treatment. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; Symptom Severity Scale (SSS); and Functional Status Scale (FSS) were used for outcome assessment. Both clinically and statistically significant changes in intensity of pain with activity (95% confidence interval [CI], 2.5-4.2; p = 0.000), night pain (p = 0.000, 95% CI, 3.2-5.7), DASH questionnaire (95% CI, 12.0-21.9; p = 0.000), SSS (95% CI, 0.64-1.15; p = 0.003), and FSS (95% CI, 0.41-0.97; p = 0.029) were found between the treatment and placebo groups. Statistically significant reduction in number of patients with positive results on the Phalen test (87%; p = 0.000), Tinel sign (73%; p = 0.000), and hand paresthesia (80%; p = 0.000) was noted in the treatment group. During 6-month follow-up, 86% of patients in the treatment group remained pain free and had no functional limitations. OBFT can be a viable and effective treatment for improving symptoms and functional limitations associated with chronic carpal tunnel syndrome.

Abstract Objectives: Biofield treatments have been used for pain control in patients with cancer and chronic pain. However, research on the effect of biofield treatment on specific somatic disorders is lacking. This study intends to investigate the effect of oscillating biofield therapy (OBFT) on symptoms of carpal tunnel syndrome. Design: Randomized, placebo-controlled, double-blind study. Participants: Thirty patients with chronic carpal tunnel syndrome participated in the study. Intervention: Patients were randomly assigned to active or placebo treatment groups. Those in the treatment group received six sessions of OBFT with intention to treat during a period of 2 weeks. Patients in the placebo group had the same number of treatment sessions with mock OBFT treatment. Outcome measure: The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire; Symptom Severity Scale (SSS); and Functional Status Scale (FSS) were used for outcome assessment. Results: Both clinically and statistically significant changes in intensity of pain with activity (95% confidence interval [CI], 2.5–4.2; p = 0.000), night pain (p = 0.000, 95% CI, 3.2–5.7), DASH questionnaire (95% CI, 12.0–21.9; p = 0.000), SSS (95% CI, 0.64–1.15; p = 0.003), and FSS (95% CI, 0.41–0.97; p = 0.029) were found between the treatment and placebo groups. Statistically significant reduction in number of patients with positive results on the Phalen test (87%; p = 0.000), Tinel sign (73%; p = 0.000), and hand paresthesia (80%; p = 0.000) was noted in the treatment group. During 6-month follow-up, 86% of patients in the treatment group remained pain free and had no functional limitations. Conclusion: OBFT can be a viable and effective treatment for improving symptoms and functional limitations associated with chronic carpal tunnel syndrome. PMID:27487406

To examine whether cognitive complaints after treatment for breast cancer are associated with detectable changes in brain activity during multitasking. Eighteen patients who were scheduled to receive chemotherapy performed a functional magnetic resonance imaging multitasking task in the scanner before the start of treatment (t1) and 4 to 6 months after finishing treatment (t2). Sixteen patients who were not scheduled to receive chemotherapy and 17 matched healthy controls performed the same task at matched intervals. Task difficulty level was adjusted individually to match performance across participants. Statistical Parametric Mapping 8 (SPM8) software was used for within-group, between-group, and group-by-time interaction image analyses. Voxel-based paired t tests revealed significantly decreased activation (P < .05) from t1 to t2 at matched performance in the multitasking network of chemotherapy-treated patients, whereas no changes were noted in either of the control groups. At baseline, there were no differences between the groups. Furthermore, in contrast to controls, the chemotherapy-treated patients reported a significant increase in cognitive complaints (P < .05) at t2. Significant (P < .05) correlations were found between these increases and decreases in multitasking-related brain activation. Moreover, a significant group-by-time interaction (P < .05) was found whereby chemotherapy-treated patients showed decreased activation and healthy controls did not. These results suggest that changes in brain activity may underlie chemotherapy-induced cognitive complaints. The observed changes might be related to chemotherapy-induced damage to the brain or reduced connectivity between brain regions rather than to changes in effort or changes in functional strategy. To the best of our knowledge, this is the first longitudinal study providing evidence for a relationship between longitudinal changes in cognitive complaints and changes in brain activation after chemotherapy. © 2014 by American Society of Clinical Oncology.

To investigate the effects of short-term light therapy with 890-nm radiation on pain, physical activity, and postural stability in patients with knee osteoarthritis (OA). A double-blind, randomized, placebo-controlled study. Rehabilitation clinic. Women (n=62) and men (n=10) with a mean age of 61.2 years (range, 40-88y). All patients fulfilled the combined clinical and radiographic criteria for knee OA as established by the American College of Rheumatology, and all had obtained a Kellgren-Lawrence score of 2 or more. Participants received 6 sessions, lasting 40 minutes each, of active or placebo radiation treatment over the knee joints for 2 weeks (wavelength, 890nm; radiant power output, 6.24W; power density, 34.7mW/cm(2) for 40 minutes; total energy, 41.6J/cm(2) per knee per session). Participants were assessed weekly over 4 weeks using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain, stiffness, and physical function. Physical activity (timed stair climbing, 10-m fast-speed walking, and chair-rising time) and postural stability (using the postural stability evaluation system) were also assessed. The pain score on WOMAC was the primary outcome variable. Data were analyzed by repeated-measures analysis of covariance. Compared with baseline, no significant improvement was observed between groups for pain (P=.546), stiffness (P=.573), or physical function (P=.904). No significant improvement was noted for physical activity including the 10-m fast-speed walking time (P=.284), stair-climbing time (P=.202), stair-descending time (P=.468), chair-rising time (P=.499), or postural stability (P=.986) at the 4 follow-up assessments. Follow-up assessments were conducted after 1 week of treatment (thus, after 3 treatments); after 2 weeks of treatment (thus, after 6 treatments); and 1 and 2 weeks, respectively, after treatment was terminated. Although we found a significant time effect for the 10-m fast-speed walking time (P<.001) in the 2 groups, and a significant group effect in the improvement of stair-climbing time in the treatment group (P=.032), the group × time interaction effects were not significant. Short-term 890-nm radiation therapy for patients with knee OA provided no beneficial effect in improving pain, physical activity, and postural stability.

The aim of this study was to describe and evaluate a physiotherapy program targeted to reduce pain intensity and improve the daily functioning of diabetics with shoulder problems. It was hypothesized that patients receiving specific physiotherapy treatment improved more frequently and rapidly than diabetic patients followed up without specific physiotherapeutic intervention. A pre-post treatment design was completed for a group of 10 subjects. The treatment protocol, also applied during the daily activities of the subjects, was aiming at reducing pain intensity and shoulder stiffness and improving impaired functioning in daily activities by muscle relaxation, light-load exercise and enhancing proper shoulder co-ordination. The group analysis showed significant decrease of pain intensity level as well as improved shoulder functioning and sustained level of subject self-efficacy beliefs throughout the study period. The results suggest that it is possible to relieve shoulder pain intensity and improve daily activities of patients with diabetes-related shoulder problems by employing a physiotherapy program focusing on muscle relaxation, light-load exercise and on the enhancement of proper shoulder co-ordination in daily activities. A physiotherapy program can be effective in reducing pain and improving shoulder function in diabetics with shoulder problems. The treatment should focus on muscle relaxation, light-load exercise and on the enhancement of proper shoulder co-ordination in daily activities.

Cognitive processing therapy (CPT), an evidence-based treatment for posttraumatic stress disorder (PTSD), has not been tested as an individual treatment among active-duty military. Group CPT may be an efficient way to deliver treatment. To determine the effects of CPT on PTSD and co-occurring symptoms and whether they differ when administered in an individual or a group format. In this randomized clinical trial, 268 active-duty servicemembers consented to assessment at an army medical center from March 8, 2012, to September 23, 2014, and were randomized to group or individual CPT. Inclusion criteria were PTSD after military deployment and stable medication therapy. Exclusion criteria consisted of suicidal or homicidal intent or psychosis. Data collection was completed on June 15, 2015. Analysis was based on intention to treat. Participants received CPT (the version excluding written accounts) in 90-minute group sessions of 8 to 10 participants (15 cohorts total; 133 participants) or 60-minute individual sessions (135 participants) twice weekly for 6 weeks. The 12 group and individual sessions were conducted concurrently. Primary measures were scores on the Posttraumatic Symptom Scale-Interview Version (PSS-I) and the stressor-specific Posttraumatic Stress Disorder Checklist (PCL-S); secondary measures were scores on the Beck Depression Inventory-II (BDI-II) and the Beck Scale for Suicidal Ideation (BSSI). Assessments were completed by independent evaluators masked to treatment condition at baseline and 2 weeks and 6 months after treatment. Among the 268 participants (244 men [91.0%]; 24 women [9.0%]; mean [SD] age, 33.2 [7.4] years), improvement in PTSD severity at posttreatment was greater when CPT was administered individually compared with the group format (mean [SE] difference on the PSS-I, -3.7 [1.4]; Cohen d = 0.6; P = .006). Significant improvements were maintained with the individual (mean [SE] PSS-I, -7.8 [1.0]; Cohen d = 1.3; mean [SE] PCL-S, -12.6 [1.4]; Cohen d = 1.2) and group (mean [SE] PSS-I, -4.0 [0.97]; Cohen d = 0.7; mean [SE] PCL-S, -6.3 [1.4]; Cohen d = 0.6) formats, with no differences in remission or severity of PTSD at the 6-month follow-up. Symptoms of depression and suicidal ideation did not differ significantly between formats. Individual treatment resulted in greater improvement in PTSD severity than group treatment. Depression and suicidal ideation improved equally with both formats. However, even among those receiving individual CPT, approximately 50% still had PTSD and clinically significant symptoms. In the military population, improving existing treatments such as CPT or developing new treatments is needed. clinicaltrials.gov identifier: NCT02173561.

Angiotensin-converting enzyme inhibitors are treatment of choice in hypertensive patients. Clinically used inhibitors exhibit a structural similarity to naturally occurring peptides. This study evaluated antihypertensive and cardioprotective effects of ACE-inhibiting peptides derived from food proteins in spontaneously hypertensive rats. Isoleucine-tryptophan (in vitro IC50 for ACE = 0.7 μm), a whey protein hydrolysate containing an augmented fraction of isoleucine-tryptophan, or captopril was given to spontaneously hypertensive rats (n = 60) over 14 weeks. Two further groups, receiving either no supplement (Placebo) or intact whey protein, served as controls. Systolic blood pressure age-dependently increased in the Placebo group, whereas the blood pressure rise was effectively blunted by isoleucine-tryptophan, whey protein hydrolysate and captopril (-42 ± 3, -38 ± 5, -55 ± 4 mm Hg vs. Placebo). At study end, myocardial mass was lower in isoleucine-tryptophan and captopril groups but only partially in the hydrolysate group. Coronary flow reserve (1 μm adenosine) was improved in isoleucine-tryptophan and captopril groups. Plasma ACE activity was significantly decreased in isoleucine-tryptophan, hydrolysate and captopril groups, but in aortic tissue only after isoleucine-tryptophan or captopril treatment. This was associated with lowered expression and activity of matrix metalloproteinase-2. Following isoleucine-tryptophan and captopril treatments, gene expression of renin was significantly increased indicating an active feedback within renin-angiotensin system. Whey protein hydrolysate and isoleucine-tryptophan powerfully inhibit plasma ACE resulting in antihypertensive effects. Moreover, isoleucine-tryptophan blunts tissue ACE activity, reduces matrix metalloproteinase-2 activity and improves coronary flow reserve. Thus, whey protein hydrolysate and particularly isoleucine-tryptophan may serve as innovative food additives with the goal of attenuating hypertension. © 2015 Scandinavian Physiological Society.

The efficacy of platelet-rich plasma (PRP) in periodontal regeneration is not well understood and the definite clinical viability of blood derived platelets lacks clarity. Also, the use of thrombin for platelet activation is disputed. Hence, the purpose of this study was to evaluate the efficacy of blood derived platelets without thrombin activation, alone or in combination with bovine anorganic bone mineral (ABM), in the treatment of human periodontal intrabony defects. PRP was prepared using a simple tabletop centrifuge and activated using calcium chloride without the addition of thrombin. This PRP was used alone (in Group A) and in combination with bovine ABM (in Group B) in the treatment of human periodontal angular defects. Both the control and the test groups showed definite improvement in clinical parameters. On comparison, however, there was a statistically significant improvement in the probing pocket depths and relative attachment level in Group B over Group A at 3 and 6 months intervals, whereas at the end of 9 months this difference was not statistically significant. There was no statistically significant difference between the groups with respect to the relative defect depth. Within the limitations of this study and the type of PRP used, i.e. without thrombin mediated activation, it can be concluded that both PRP and PRP combined with bovine ABM results in significant clinical improvement. Albeit statistically insignificant, there is a preponderance of better clinical results with the addition of ABM to PRP. Further studies need to be carried out on a larger sample size to confirm the results of the present study.

Ivabradine, a bradycardic agent, has been shown to stably reduce patient's heart rate (HR) in the setting of acute cardiac care. However, an association between atrial fibrillation (AF) risk and acute ivabradine treatment remains a controversial clinical issue, and has not been thoroughly investigated. Bradycardia and abnormal atrial refractoriness induced by ivabradine treatment may enhance vulnerability to AF induction, especially when vagal nerve is concurrently activated. We aimed to experimentally investigate the effects of acute ivabradine treatment with/without concurrent vagal activation on AF inducibility. In 16 anesthetized dogs, cervical vagal nerves were prepared for electrical stimulation (VS). AF induction rate (AFIR) was determined by atrial burst pacing. HR, atrial action potential duration (APD), atrial effective refractory period (ERP), and AFIR were obtained consecutively at baseline, during delivery of VS (VS alone), after intravenous injection of ivabradine 0.5 mg/kg (n = 8, ivabradine group) or saline (n = 8, saline group), and again during VS delivery (drug+VS). In the ivabradine group, ivabradine alone significantly lowered HR compared to baseline, while ivabradine+VS significantly lowered HR compared to VS alone. Contrary to expectations, there were no significant differences in trends of APD, temporal dispersion of APD, ERP, and AFIR between ivabradine and saline groups. Irrespective of whether ivabradine or saline was injected, VS significantly shortened APD and ERP, and increased AFIR. Interestingly, although bradycardia in response to ivabradine injection was more intense than that to VS alone, AFIR was significantly lower after ivabradine injection than during VS alone. We conclude that, despite its intense bradycardic effect, acute ivabradine treatment does not increase AF inducibility irrespective of underlying vagal activity. This study may constitute support for the safety of using ivabradine in the setting of acute cardiac care.

[Electrical stimulation therapy and its effects on the general activity of motor impaired cerebral palsied children; a comparative study of the Bobath physiotherapy and its combination with the Hufschmidt electrical stimulation therapy (author's transl)].

The purpose of this study was to answer the following questions: (1) Is it more effective to treat spastic cerebral palsy with the Hufschmidt electrical stimulation therapy combined with the Bobath neuro-development treatment or only with the Bobath therapy? (2) Can a general increase in activity be obtained by the electrotherapeutic muscle stimulation? A test group (combined Hufschmidt/Bobath therapy) and a control group (Bobath), both consisting of 10 subjects, were observed for four months. The duration of observation was divided into two four months treatment periods with a rest interval of two months in between. At the start of therapeutic measures, motor activity and psychic condition were tested with corresponding motormetric and psychodiagnostic techniques; three check-up examinations were carried out at the end of the first, and at the beginning and end of the second period of treatment. The motor-metric control examination showed that at the end of the first period the test group had achieved by far the better results, but at the end of the second therapeutic period, both groups were equally successful. The combined electrophysiotherapy hence reached in a relatively shorter time - as it were by leaps and bounds - the optimal obtainable state of functional improvements which, with the Bobath therapy alone, can be effected more slowly but with more continuity. The psychodiagnostic controls clearly indicate that the electrical stimulation produced an unspecified increase in activity, especially after the first phase of treatment, whereas in the second phase this could only be proven in a graded form. The report closes with an examination of the results and their consequences for the implementation of the treatment for cerebral palsied children.

Objective: To study the impact of negative expectation related to receiving a placebo (the “lessebo effect”) on efficacy outcome measures of symptomatic treatments in Parkinson disease (PD). Methods: We conducted meta-analyses of double-blind randomized controlled trials (RCTs) of dopamine agonists in PD and compared the pooled mean score change of the motor section of the Unified Parkinson's Disease Rating Scale (mUPDRS) across active treatment arms according to the presence of a placebo arm or the probability of placebo assignment (0%, <50%, and 50%) of the original RCT. A mixed-effects model was used. Heterogeneity was assessed by subgroup analyses and meta-regression modeling. Results: A total of 28 study arms were extracted from active-controlled trials (3,277 patients) and 42 from placebo-controlled trials (4,554 patients). The overall difference between groups in the pooled mean score change in the mUPDRS was 1.6 units (95% confidence interval [CI] 0.2, 3.0; p = 0.023), in favor of the active-controlled group. In subgroup analyses, this difference was of higher magnitude in the early PD group without motor fluctuations (3.3 mUPDRS units, 95% CI 1.1, 5.4; p = 0.003) and for study duration ≤12 weeks (4.1 mUPDRS units, 95% CI 1.0, 7.2; p = 0.009). There was no between-group difference using probability of placebo assignment as criterion. Conclusions: This study shows that the use of a placebo can be associated with a clinically significant reduction in the magnitude of change of the mUPDRS after an active treatment in RCTs for PD. These new findings have potential implications in the development of new treatments and appraisal of current treatment options for PD and possibly for other neurologic disorders. PMID:24658930

Radiation safety is an integral part of targeted radionuclide therapy. The aim of this work was to study the external dose rate and retained body activity as functions of time in differentiated thyroid carcinoma patients receiving 131I therapy. Seventy patients were stratified into two groups: the ablation group (A) and the follow-up group (FU). The patients’ external dose rate was measured, and simultaneously, their retained body radiation activity was monitored at various time points. The equations of the external dose rate and the retained body activity, described as a function of hours post administration, were fitted. Additionally, the release time for patients was calculated. The reduction in activity in the group receiving a second or subsequent treatment was more rapid than the group receiving only the initial treatment. Most important, an expeditious method was established to indirectly evaluate the retained body activity of patients by measuring the external dose rate with a portable radiation survey meter. By this method, the calculated external dose rate limits are 19.2, 8.85, 5.08 and 2.32 μSv·h−1 at 1, 1.5, 2 and 3 m, respectively, according to a patient’s released threshold level of retained body activity <400 MBq. This study is beneficial for radiation safety decision-making. PMID:25337944

Idiopathic pulmonary fibrosis is a progressive fatal lung disease characterized by excessive collagen deposition, with no effective treatments. We investigated the efficacy of natural products with high anti-inflammatory activity, such as passion fruit peel extract (PFPE), in a mouse model of bleomycin-induced pulmonary fibrosis (PF). C57BL/6J mice were subjected to a single intratracheal instillation of bleomycin to induce PF. Daily PFPE treatment significantly reduced loss of body mass and mortality rate in mice compared with those treated with bleomycin. While bleomycin-induced PF resulted in elevated total numbers of inflammatory cells, macrophages, lymphocytes, and neutrophils in bronchoalveolar lavage fluid on both days 7 and 21, PFPE administration significantly attenuated these phenomena compared with bleomycin group. On day 7, the decreased superoxide dismutase and myeloperoxidase activities observed in the bleomycin group were significantly restored with PFPE treatment. On day 21, enhanced hydroxyproline deposition in the bleomycin group was also suppressed by PFPE administration. PFPE treatment significantly attenuated extensive inflammatory cell infiltration and accumulation of collagen in lung tissue sections of bleomycin-induced mice on days 7 and 21, respectively. Our results indicate that administration of PFPE decreased bleomycin-induced PF because of anti-inflammatory and antioxidant activities.

To evaluate the craniofacial changes induced by functional appliances with special regard to the oro and nasopharyngeal sagittal airway dimensions in subjects with dentoskeletal Class II malocclusions when compared with an untreated Class II control group immediately after therapy and at long-term observation. A group of 40 patients (21 females and 19 males) with Class II malocclusion treated consecutively either with a Bionator or an Activator followed by fixed appliances was compared with a matched control group of 31 subjects (16 females and 15 males) with untreated Class II malocclusion. The treated sample was evaluated at T1, start of treatment (mean age: 9.9 ± 1.4 years); T2, end of functional treatment and prior to fixed appliances (mean age: 11.9 ± 1.3 years); and T3, long-term observation at the end of growth (mean age: 18.2 ± 2.1 years). Statistical comparisons were performed with independent sample t tests at T1 (baseline characteristics) and for the T1-T2, T2-T3, and T1-T3 changes. During active treatment the treated group showed a significant increment in lower airway dimension (PNS-AD1), as well as a significant improvement in the upper airway dimension (PNS-AD2). A significant decrease in the upper adenoid size (AD2-H) was also found. In the longterm evaluation, a significant increase in both lower and upper airway thickness (PNS-AD1; PNS-AD2) and a significant decrease in the upper adenoid thickness were still present in the treated group. The treatment with functional appliances produced significant favorable changes during active treatment in the oro- and nasopharyngeal sagittal airway dimensions in dentoskeletal Class II subjects when compared with untreated controls, and these changes were stable in the long-term.

In this study, we determined the effects of hederagenin isolated from Akebia quinata fruit on alcohol-induced hepatotoxicity in rats. Specifically, we investigated the hepatoprotective, anti-inflammatory, and anti-apoptotic effects of hederagenin, as well as the role of AKT and mitogen-activated protein kinase (MAPK) signaling pathways in ethanol-induced liver injury. Experimental animals were randomly divided into three groups: normal (sham), 25% ethanol, and 25% ethanol + hederagenin (50 mg/kg/day). Each group was orally administered the respective treatments once per day for 21 days. Acetaldehyde dehydrogenase-2 mRNA expression was higher and alcohol dehydrogenase mRNA expression was lower in the ethanol + hederagenin group than those in the ethanol group. Pro-inflammatory cytokines, including TNF-α, IL-6, and cyclooxygenase-2, significantly increased in the ethanol group, but these increases were attenuated by hederagenin. Moreover, Western blot analysis showed increased expression of the apoptosis-associated protein, Bcl-2, and decreased expression of Bax and p53 after treatment with hederagenin. Hederagenin treatment attenuated ethanol-induced increases in activated p38 MAPK and increased the levels of phosphorylated AKT and ERK. Hederagenin alleviated ethanol-induced liver damage through anti-inflammatory and anti-apoptotic activities. These results suggest that hederagenin is a potential candidate for preventing alcoholic liver injury.

Background : Sugar alcohols such as xylitol are incorporated in a number of oral hygiene products for their anti-cariogenic properties while chewing gum is known to be beneficial to oral hygiene. Objective : The aim of this study was to determine the composition of the dental plaque microbiota in patients with active caries before and after using a chewing gum supplemented with maltitol. Design : Forty subjects with active caries were randomly allocated to chew maltitol gum or gum base for two weeks. A healthy control group used gum base for two weeks. Plaque samples were collected before and after treatment and the microbiota analysed by pyrosequencing of 16S rRNA genes. Results : A total of 773,547 sequences were obtained from 117 samples. There was no difference in structure of the bacterial communities between groups (AMOVA). There was a significant difference in community membership between groups, (AMOVA, p=0.009). There was a significant difference between the control group after treatment and the maltitol patient group after treatment (p<0.001). A. naeslundii HOT-176 and Actinomyces HOT-169 were significantly reduced following use of maltitol chewing gum in patients. Conclusions : This study has shown that chewing gum containing maltitol had minor effects on the composition of the plaque microbiome.

Abstract Failure of male pronucleus formation has hampered the success of intracytoplasmic sperm injection (ICSI) in swamp buffalo. The aim of the present study was to improve male pronucleus formation by pretreating sperm with various chemicals before ICSI. In Experiments1 and 2, sperm were treated according to one of the following protocols: (1) 0.1% Triton-X 100 (TX) for 1 min, (2) 10 µM calcium ionophore (CaI) for 20 min, (3) freezing and thawing (FT) without any cryoprotectant, or (4) no treatment (control). These sperm treatment groups then either did or did not receive additional sperm treatment with 5 mM dithiothreitol (DTT) for 20 min. Acrosomal integrity (Experiment 1) and DNA fragmentation (Experiment 2) were evaluated in the sperm before ICSI. In Experiment 3, oocytes matured in vitro were subjected to ICSI using pretreated sperm as described above and then were cultured either with or without activation. The TX- and CaI-treated sperm caused an increase in the number of acrosome-loss sperm, whereas the FT treatment and control increased the proportion of acrosome-reacted sperm (P<0.05). The DNA fragmentation did not differ among treatments (P>0.05). At 18 h post-ICSI, pronucleus (PN) formation was found only in activated oocytes. The majority of the activated ICSI oocytes contained intact sperm heads. Normal fertilization was observed in the CaI and FT treatment groups and control group when sperm were treated with DTT before ICSI. In conclusion, DTT treatment of sperm with reacted acrosomes before ICSI together with activation of the ICSI oocytes is important for successful male pronucleus formation. PMID:23132520

Bamboo charcoal (BC) accompanied silver (Ag) nanocomposite is synthesized through sol-gel method. The produced BC/Ag nanocomposite was surface modified by air and oxygen plasma treatments. Silver ions (Ag+) will serve to improve the antibacterial activity as well as the surface area of BC. Plasma treatment has improved the surface functional groups, crystalline intensity and antibacterial activity of the prepared nanocomposite. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) studies show that Ag nanoparticles have good agreement with BC and the particle size has a mean diameter of 20-40nm. We observe the carboxyl functional groups in Fourier transform infrared spectroscopy (FTIR) after the oxygen plasma treatment. Moreover surface area and adsorption were analyzed by using the Brunauer, Emmett and Teller (BET) surface area (SBET) and UV-Vis spectroscopy.

Periodontally accelerated osteogenic orthodontics (PAOO) combines periodontal therapy with orthodontic therapy, which minimises treatment time. This study compared the effectiveness of a bovine-derived xenograft with that of bioactive glass when combined with PAOO for the treatment of adult patients with moderate crowding of the teeth. In this prospective, single-masked clinical trial, 33 orthodontic patients (20 women, 13 men; mean age 21.2 ± 1.43 [18 - 27] years), were randomly allocated to one of three groups. Group 1 underwent a modified corticotomy technique on the labial side only, whereas group 2 was treated with the same technique combined with PAOO using a bovine-derived xenograft and group 3 was treated in the same way but combining PAOO with bioactive glass. The total treatment duration was recorded from the start of active orthodontic treatment, immediately after corticotomy, and at the time of debonding. Probing depth was evaluated clinically and bone density and root length were evaluated radiographically on the day of surgery (baseline, T1), post-treatment at debonding (T2), and 9 months post-treatment (T3). The duration of orthodontic treatment was markedly reduced to an average of 11.4 ± 0.14 weeks in all groups. All probing depths were < 3 mm, the interdental papillae were well preserved, there was no loss of tooth vitality, and there was no evidence of significant apical root resorption at any time interval. All groups showed a decrease in mean bone density at T2 followed by an increase at T3. The net percentage change that occurred between baseline and 9 months post-treatment was significantly different between the three groups. Groups 2 and 3, where grafts were incorporated, demonstrated a statistically significant greater increase in bone density than group 1 at T3. Combination of orthodontic treatment and periodontal surgery is an effective treatment for adult patients that decreases the duration of active treatment and reduces the risk of root resorption. Use of a bovine-derived xenograft with modified corticotomy provided superior benefits in terms of increased bone density than did the use of bioactive glass. The study was retrospectively registered at ClinicalTrials.gov under Clinical Trial Registration Number: NCT02796911 .

Chronic pain is a significant problem for many individuals following spinal cord injury (SCI). Unfortunately, SCI-related neuropathic pain has proven to be largely refractory to analgesic medications and other available treatments. Cranial electrotherapy stimulation (CES) has been effective in managing some types of pain. It involves the application of a small amount of current through the head via ear clip electrodes. Explore the effectiveness of CES for neuropathic pain in persons with SCI and chronic pain. Multi-site, double-blind, sham-controlled study. Adults with SCI and chronic neuropathic pain at or below the level of injury were randomized to receive active or sham CES. Application of active CES or sham CES 1 hour daily for 21 days. Six-month open-label phase to assess 'as-needed' CES use. Change in pre- to post-session pain ratings as well as change in pain intensity, pain interference, pain quality, pain beliefs and coping strategies, general physical and mental health status, depressive symptomatology, perceived stress, and anxiety pre- to post-treatment. The active group reported a significantly greater average decrease in pain during daily treatments than the sham group (Kruskal-Wallis chi-square = 4.70, P < 0.05). During the 21-day trial, there was a significant group × time interaction for only one outcome variable; the active group showed larger pre- to post-treatment decreases in pain interference than the sham group did (F = 8.50, P < 0.01, d = 0.59). On average, CES appears to have provided a small but statistically significant improvement in pain intensity and pain interference with few troublesome side effects. Individual results varied from no pain relief to a great deal of relief.

This study investigated the impact of three commonly used cardiovascular model-assisted activities on student learning and student attitudes and perspectives about science. College students enrolled in a Human Anatomy and Physiology course were randomly assigned to one of three experimental groups (organ dissections, virtual dissections, or plastic models). Each group received a 15-min lecture followed by a 45-min activity with one of the treatments. Immediately after the lesson and then 2 mo later, students were tested on anatomy and physiology knowledge and completed an attitude survey. Students who used plastic models achieved significantly higher overall scores on both the initial and followup exams than students who performed organ or virtual dissections. On the initial exam, students in the plastic model and organ dissection treatments scored higher on anatomy questions than students who performed virtual dissections. Students in the plastic model group scored higher than students who performed organ dissections on physiology questions. On the followup exam, when asked anatomy questions, students in the plastic model group scored higher than dissection students and virtual dissection students. On attitude surveys, organ dissections had higher perceived value and were requested for inclusion in curricula twice as often as any other activity. Students who performed organ dissections were more likely than the other treatment groups to agree with the statement that "science is fun," suggesting that organ dissections may promote positive attitudes toward science. The findings of this study provide evidence for the importance of multiple types of hands-on activities in anatomy laboratory courses.

Twelve lactating Murrah buffalo, divided into control and treatment group of six animals each, were used to study the effect of melatonin and controlled internal drug release (CIDR) device treatment on the resumption of ovarian activity during out-of-breeding season (summer solstice). Treated group implanted with melatonin (18-mg melatonin/50-kg body weight) for 45 days and then animals of both groups received CIDR for 9 days. All animals received intramuscular 500 IU eCG, at day before CIDR removal, and 10-μg GnRH at day after CIDR withdrawal. All animals were subjected to estrus detection daily. Blood samples in conjunction with transrectal ultrasonography were performed once a week to determine serum concentrations of melatonin, progesterone, and antioxidant enzyme activities, as well as to monitor the ovarian activity. Melatonin treatment resulted in an increase (P < 0.01) in the overall mean superoxide dismutase activity. Melatonin and CIDR increased the diameter of CL (P < 0.01) and plasma progesterone concentration (P < 0.05). In addition, melatonin and CIDR exhibited superior ability to maintain presence of CL at Day 21 and Day 30 after artificial insemination and achieved higher percentage of conception rate than control. In conclusion, the CIDR treatment preceded by melatonin improved the reproductive performance in lactating buffaloes during out-of-breeding season under tropical conditions.

Rotator cuff problems are common causes of pain and restriction of movement in shoulder. The aim of this study to compare the effect of intra-articular injection of corticosteroid and conventional transcutaneous electrical nerve stimulator (TENS) treatment in treatment of rotator cuff tendinitis. Subjects were randomly allocated into Group 1 (intra-articular injection of corticosteroid) and Group 2 (conventional transcutaneous electrical nerve stimulation-TENS). Outcome measurements were performed using the Visual Analogue Scale (VAS) for pain, range of motion (ROM), the Shoulder Disability Questionnaire (SDQ), the Short Form-36 (SF-36), and Beck Depression Scale (BDS) questionnaires and paracetamol consumption. In both groups, significant improvement was observed in all weeks in VAS, ROM and SDQ scores (P<0.05). Improvement was detected in most of the SF36 scores at the end of the treatment in both groups (P<0.05), while no significant change was observed in BDI score (P>0.05). In both treatment groups, paracetamol consumption decreased in time (P<0.05). When the groups were compared, a significant difference was found between the groups in favor of Group 1 in terms of VAS-at night and VAS-at rest in weeks 1, 4 and 12, and VAS-during movement in week 1 and 12 (P<0.05). The comparison of two groups revealed a significant difference in favor of Group 1 in weeks 1 in the passive abduction and the active and passive IR ROM measurements (P<0.05). There was also a significant difference in favor of Group 1 observed in weeks 1 in SDQ scores (P<0.05). Intra-articular injection of corticosteroid and conventional TENS are efficient in the treatment of rotator cuff tendinitis. When two treatments are compared, it may be concluded that intra-articular steroid injection was more effective especially in the first weeks regarding pain, ROM and disability. Otherwise, use of TENS allow to patients to increase activity level, improve function and quality of life like that in our study. TENS, as it is cheaper, non-invasive, more easily performed and efficient, may be preferable for the treatment of shoulder pain. Further studies are needed to include these results in the prospective treatment guidelines.

Clausena excavata is a well-known plant used in folkloric medicine for the treatment of different ailments. This study aimed to determine the in vitro cytoxicity of its leaf solvent extracts as well as the in vivo wound healing and antioxidant activities of the methanolic extracts of C. excavata (MECE). HaCaT (keratocyte) and Vero cell lines were used for evaluation of the in vitro cytotoxic effects, while the in vivo wound healing and antioxidant activities were determined in skin wounds inflicted on rats. Twenty adult male Sprague-Dawley rats were divided into five groups of four animals each. Approximately 3.14 cm(2) excisional wound was inflicted on the nape of each rat following anesthesia. The treatment groups received topical application of MECE at 50 mg/mL (MECE-LD [low dose]), 100 mg/mL (MECE-MD [medium dose]), and 200 mg/mL (MECE-HD [high dose]), while the negative control group was treated with gum acacia in normal saline and the positive control group with intrasite gel. Wound contraction was evaluated on days 5, 10, and 15 after wound infliction, and tissue from wound area was collected at day 15 post-wound infliction for antioxidant enzyme evaluation and histopathological analyses. Generally, Vero cells were more resistant to the cytotoxic effects of the solvent extracts as compared with HaCaT cells. Chloroform (CH) and ethyl acetate (EA) extracts of C. excavata were toxic to HaCaT cells at 200 and 400 µg/mL, but the same concentrations showed higher (P<0.05) viability in Vero cells. There was significantly (P<0.01) greater wound contraction at days 10 and 15 post-wound infliction in all the treatment groups than in the control groups. Histopathologically, the MECE-HD-treated wound showed significantly (P<0.05) lesser inflammatory cell proliferation, degeneration, and distribution of granulation tissue than other groups. Similarly, the degree of collagen maturation, angiogenesis, and collagen distribution were significantly (P<0.05) lower in MECE-HD than in other groups. The MECE-HD, MECE-MD, and intrasite treatment groups showed a significantly (P<0.05) higher number of VEGF-positive and TGF-β1-positive cells in the skin wound than the control groups. The activities of superoxide dismutase and catalase were significantly (P<0.01) higher in the MECE-HD and intrasite treatment groups than in the other groups. Lipid peroxidase activity of the treated groups was significantly (P<0.01) lower than that in the control group. The study showed that MECE is a potent wound healing agent through anti-inflammatory and antioxidant effects that enhanced the rate of wound contraction, re-epithelialization, and collagen deposition. The effect of MECE is suggested to be due to its high polyphenolic compound content.

The purpose of this study was to investigate the efficacy of LLLT in the treatment of trigger points (TrPs) that are associated with rotator cuff tendonitis. A double-blind randomized controlled trail was conducted. Sixty patients were randomly allocated to one of two groups: sham or laser therapy. The laser (Excel, Omega Universal Technologies Ltd, London, UK) parameters used were a wavelength of 820 nm, a power output of 100 mW, a frequency of 5000 Hz (modulated) and energy density of 32 J/cm2. The two groups received a course of 12 treatment sessions for four weeks (3 sessions per week). Pain, functional activities (as measured using the Shoulder Pain and Disability Index, SPADI), pressure pain threshold (PPT) and range of motion (ROM) were assessed pre and post treatment, with a three month follow-up assessment. Significant improvements in pain (p < 0.001) were observed for the laser group (6 cm median improvement on a 10 cm VAS) compared to the sham group (2 cm median improvement) immediately post treatment. The improvements in the laser group continued post treatment with a 7 cm median improvement observed at three month follow-up. Similar between group differences were observed for ROM (p < 0.01), functional activities (p <= 0.001) and PPT (p <= 0.05). The findings of the current study suggested that LLLT is effective in treating patients with TrPs associated with rotator cuff tendonitis, when using the parameters described. However, the mechanism of its action is not yet clear, and will require further investigation.

This study used mixed methods to explore youth attitudes about recovery-related needs and important drug-avoidance behaviors after treatment. Focus groups were conducted with 118 substance using youth in treatment (four residential and 10 outpatient settings) throughout Los Angeles County. The average age was 17.4 (SD = 2.9); 78.3% were male, 66.1% Latino; and most were in treatment for primary marijuana (40.9%) or methamphetamine (30.4%) abuse. Quantitatve results from the drug-avoidance activity survey identified the following factors youth rated as important to their recovery after treatment: lifestyle improvement activities (95.7%); changing personal drug behaviors (89.6%); drug environment/culture change activities (82.5%); with the least important being therapeutic activities (78.5%). Qualitative findings from focus groups that asked what youth think are important for recovery programs to address after treatment revealed the following four areas: (1) recovery promotion to developmentally appropriate activities (95%); (2) facilitating the use of coping skills to deal with stress (85%); (3) offering alternative recovery support options (not just abstinence only) (75%); and (4) continuing to provide substance use education (65%). Findings highlight essential aspects of recovery in terms of need and drug-avoidance behaviors considered important to youth in treatment. Such information will help to better address clinical and recovery support models aimed at relapse prevention to ensure that the perceived problems of substance-abusing youth are adequately met.

In sublingual immunotherapy, optimal doses are a key factor for therapeutic outcomes. The aim of this study with tablets containing carbamylated monomeric house dust mite allergoids was to determine the most effective and safe dose. In this double-blind, placebo-controlled dose-finding study, 131 patients with house dust mite-induced allergic rhinoconjunctivitis were randomized to 12-week treatments with 300 UA/day, 1000 UA/day, 2000 UA/day, 3000 UA/day or placebo. Conjunctival provocation tests (CPT) were performed before, during and after treatment. The change in mean allergic severity (primary endpoint), calculated from the severity of the CPT reaction, and the proportion of patients with an improved CPT threshold (secondary endpoint) determined the treatment effect. The mean allergic severity decreased in all groups, including the placebo group. It was lower in all active treatment groups (300 UA/day: 0.14, 1000 UA/day: 0.15, 2000 UA/day: 0.10, 3000 UA/day: 0.15) than in the placebo group (0.30). However, this difference was not statistically significant (P < 0.1). The percentage of patients with an improved CPT threshold was higher in the active treatment groups (300 UA/day: 73.9%; 1000 UA/day: 76.0%; 2000 UA/day: 88.5%; 3000 UA/day: 76.0%) than in the placebo group (64.3%). The difference between placebo and 2000 UA/day was statistically significant (P = 0.04). In 13 (10%) exposed patients, a total of 20 treatment-related adverse events of mild severity were observed. The 12-week daily treatment using 2000 UA/day monomeric allergoid sublingual tablets is well tolerated and reduces the CPT reaction in house dust mite-allergic patients. © 2016 The Authors.

Tinnitus is associated with neural hyperactivity in the central nervous system (CNS). Salicylate is a well-known ototoxic drug, and we induced tinnitus in rats using a model of long-term salicylate administration. The gap pre-pulse inhibition of acoustic startle test was used to infer tinnitus perception, and only rats in the chronic salicylate-treatment (14 days) group showed evidence of experiencing tinnitus. After small animal positron emission tomography scans were performed, we found that the metabolic activity of the inferior colliculus (IC), the auditory cortex (AC), and the hippocampus (HP) were significantly higher in the chronic treatment group compared with saline group (treated for 14 days), which was further supported by ultrastructural changes at the synapses. The alterations all returned to baseline 14 days after the cessation of salicylate-treatment (wash-out group), indicating that these changes were reversible. These findings indicate that long-term salicylate administration induces tinnitus, enhanced neural activity and synaptic ultrastructural changes in the IC, AC, and HP of rats due to neuroplasticity. Thus, an increased metabolic rate and synaptic transmission in specific areas of the CNS may contribute to the development of tinnitus. PMID:27068004

In Egypt, infection with Schistosoma mansoni (S.m.) and residues of pesticides have been considered as major environmental pollutants that adversely affect health. Effects of diazinon (DZN) and/or praziquantel (PZQ) on the levels of plasma triiodothyronine (T3), thyroxine (T4), activities of brain acetylcholinesterase (AchE) and liver alanine aminotransferase (ALT) in addition to blood reduced glutathione (GSH) in healthy and S.m. infected mice were investigated after 9 and 17 weeks of either infection or intoxication with DZN. Triiodothyronine showed significant differences among the different treatments. The group of mice treated with PZQ showed the highest levels of T3 at both time intervals. Thyroxine level showed significant differences between the two time intervals. The lowest levels of T4 were observed in the infected-PZQ group at week 17. The maximum inhibition of brain AchE activity was noticed in DZN-PZQ treated group after 9 and 17 weeks. The different treatments significantly reduced the activities of liver ALT. The highest decrease was recorded in the infected-DZN-PZQ group at week 9. All treatments significantly lowered the levels of blood GSH after 9 weeks.

Ampelopsis cantoniensis (AC) has been used as a folk medicine for reducing pain in the Taiwanese population. Our previous studies have shown that the crude extract of AC induced apoptosis in human promyelocytic leukemia HL-60 cells. In this study, the in vivo effects of AC on leukemia WEHI-3 cells and immune responses such as phagocytosis and natural killer (NK) cell activity were investigated. The weights of the livers and spleens were decreased in the AC-treated groups compared to the control groups. The AC treatment increased the percentage of CD3 and CD19 marker cells in WEHI-3-injected mice, indicating that the precursors of T and B cells were inhibited. The AC treatment promoted the activity of macrophage phagocytosis in the peripheral blood mononuclear cells (PBMC) and peritoneal cells. It was found that the NK cells from mice after treatment with AC can kill the YAC-1 target cells. Therefore, the AC treatment increased NK cell activity. In conclusion, AC can affect WEHI-3 cells in vivo and promote macrophage and NK cell activities.

This study assessed the effects of a group intervention-Siblings Coping Together (SibCT)-on siblings' and caregivers' anxiety symptoms compared to controls, and potential moderators. Seventy healthy siblings of children on or off treatment (7-16 y old, 41 males) participated in a randomized controlled trial (RCT) with 2 arms/groups: SibCT (n = 41) and an attention control (CG) (n = 34). Both groups had eight 2-hour weekly sessions. EG followed SibCT's educational, social, and problem-solving activities. CG had planned games and crafts. Siblings and caregivers self-reported on anxiety symptoms at baseline, intervention end, and 3 months later. Multivariable mixed model analyses examined the intervention effect over time, and potential moderators (gender, on/off ill child's treatment). No main effects of group or time were found in sibling scores. A group × gender interaction (P < .05) indicated that in the intervention group female siblings reported less total anxiety symptoms than male siblings, with no significant gender differences in the control group. Caregivers' total anxiety symptoms declined over time (P < .02). A group × on/off treatment interaction in physiological/panic subscale (P < .03) indicated that when ill child was on treatment, caregivers of siblings in SibCT reported less anxiety compared with caregivers of CG. There was no clear SibCT intervention effect. SibCT may benefit female siblings, and caregivers whose ill child is on active treatment. Contextual factors (gender) seem to influence psychosocial intervention in this population. Copyright © 2018 John Wiley & Sons, Ltd.

To assess the effects of active music therapy (MT) and individualized listening to music (LtM) on behavioral and psychological symptoms of dementia (BPSDs) in persons with dementia (PWDs). Randomized controlled trial. Nine Italian institutions. Persons with moderate to severe dementia and BPSDs (N = 120) were randomized to one of three treatments. All groups received standard care (SC), and two groups attended 20 individualized MT or LtM sessions, twice a week, in addition to SC. The Neuropsychiatric Inventory (NPI), Cornell Scale for Depression in Dementia (CSDD), and Cornell-Brown Scale for Quality of Life in Dementia (CBS-QoL) were administered before treatment, after treatment, and at follow-up to evaluate behavioral and psychological outcomes. A specific coding scheme (Music Therapy Check List-Dementia) was used to evaluate the MT process. Behavioral assessment did not show significant differences between groups. All groups showed a reduction over time in NPI global score (P ≤ .001), CSDD (P = .001), and CBS-QoL (P = .01). The NPI global score fell 28% in the MT group, 12% in the LtM group, and 21% in the SC group at the end of treatment. An exploratory post hoc analysis showed similar within-group improvements for the NPI Delusion, Anxiety, and Disinhibition subscales. In the MT group, communication and relationships between the music therapists and PWDs showed a positive albeit nonsignificant trend during treatment. The addition of MT or LtM to standard care did not have a significant effect on BPSDs in PWDs. Further studies on the effects of the integration of standard care with different types of music interventions on BPSD in PWD are warranted. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

Symptoms of lateral epicondylitis (LE) are attributed to degenerative changes and inflammatory reactions in the common extensor tendon induced by microscopic tears in the tissue after repetitive or overload functions of the wrist and hand extensor muscles. Conventional treatments, provided on the premise of inflammatory basis of LE, have shown 39-80% failure rate. An alternative approach suggests that symptoms of LE could be due to active tender points developed in the origin of hand and wrist extensor muscles after overuse or repetitive movements. Oscillating-energy Manual Therapy (OEMT), also known as V-spread, is a craniosacral manual technique that has been clinically used for treating tender points over the suture lines in the skull. Considering symptoms of LE may result from active tender points, the purpose of this study was to investigate the effect of OEMT on pain, grip strength, and functional abilities of subjects with chronic LE. Twenty-three subjects with chronic LE (>3mo) between ages of 24 and 72 years participated in this study. Before their participation, all subjects were screened to rule out cervical and other pathologies that could possibly contribute to their lateral elbow pain. Subjects who met the inclusion criteria were randomized into treatment and placebo treatment groups by a second (treating) therapist. Subjects were blinded to their group assignment. Subjects in the treatment group received OEMT for six sessions. During each treatment session, first a tender point was located through palpation. After proper hand placement, the therapist focused the direction of the oscillating energy on the localized tender point. Subjects in the placebo group underwent the same procedure, but the direction of the oscillating energy was directed to an area above or below the tender points, not covering the affected area. Jamar Dynamometer, Patient Specific Functional Scale (PSFS), and Numeric Rating Scale (NRS) were used to measure grip strength, functional status, and pain intensity and limited activity due to pain, respectively. The screening therapist who was blinded to the subjects' group assignment performed pretest, posttest, and six-month follow-up measurements. Subjects in the treatment group showed both clinically and statistically significant improvement in grip strength (p=0.03), pain intensity (p=0.006), function (p=0.003), and limited activity due to pain (p=0.025) compared with those in the placebo group. Follow-up data, collected after six months, showed no significant difference between posttest and follow-up measurements in functional activity (p=0.35), pain intensity (p=0.72), and activity limitation due to pain (p=0.34). Of all the subjects contacted for follow-up assessment, 91% maintained improved function and 73% remained pain free for at least six months. OEMT seems to be a viable, effective, and efficient alternative treatment for LE.

The effect of the synthetic pineal peptide Epitalon (Ala-Glu-Asp-Gly) on proliferative activity in colon tumors, and in mucosal epithelial cells adjacent to and located far from tumors was studied in rats. To evaluate the effect of Epitalon on different stages of carcinogenesis, different treatment regimens were used: during the tumor initiation stage, during the tumor-promotion stage, or during the entire process of tumor development. Eighty 2-month-old male LIO rats were exposed weekly to five subcutaneous injections of 1,2-dimethylhydrazine (DMH) at a single dose of 21 mg/kg body weight. Rats were divided into four groups. Control rats (group 1) received saline at a dose of 0.1 ml during the entire experiment. Rats in group 2 were treated with Epitalon at a dose of 1 micro g, five times a week, for 6 months, from the first injection of DMH till the end of the experiment. Rats in group 3 were treated with Epitalon after termination of the carcinogen injections. Rats in group 4 were treated with Epitalon only during the period of DMH exposure (for the first 5 weeks of the experiment). DMH induced proliferation of the secretory epithelium, and this phenomenon was accompanied by a decrease in the size of the stromal area and the area of lymph infiltration in colon tumors and in the colon mucosa adjacent to the tumors (group 1). Epitalon attenuated this effect, especially when the treatment was continued throughout the experiment (group 2). It increased the stromal areas, as well as that of lymphoid infiltration in the colon mucosa adjacent to the tumors. The intensity of lymphoid infiltration was activated in both the colon mucosa adjacent to a tumor and in the tumor. Mitotic activity of tumor cells was significantly inhibited by Epitalon when the treatment was given throughout the experiment (group 2). In parallel, a high level of apoptosis was seen in the same group. Thus, the strongest inhibitory effect of Epitalon on carcinogenesis in the colon mucosa was manifested when the treatment was continued throughout the experiment.

Context: Heart Rate Variability (HRV) indicates how heart rate changes in response to inner and external stimuli. HRV is linked to health status and it is an indirect marker of the autonomic nervous system (ANS) function. Objective: To investigate the influence of osteopathic manipulative treatment (OMT) on cardiac autonomic modulation in healthy subjects, compared with sham therapy and control group. Methods: Sixty-six healthy subjects, both male and female, were included in the present 3-armed randomized placebo controlled within subject cross-over single blinded study. Participants were asymptomatic adults (26.7 ± 8.4 y, 51% male, BMI 18.5 ± 4.8), both smokers and non-smokers and not on medications. At enrollment subjects were randomized in three groups: A, B, C. Standardized structural evaluation followed by a patient need-based osteopathic treatment was performed in the first session of group A and in the second session of group B. Standardized evaluation followed by a protocoled sham treatment was provided in the second session of group A and in the first session of group B. No intervention was performed in the two sessions of group C, acting as a time-control. The trial was registered on clinicaltrials.gov identifier: NCT01908920. Main Outcomes Measures: HRV was calculated from electrocardiography before, during and after the intervention, for a total amount time of 25 min and considering frequency domain as well as linear and non-linear methods as outcome measures. Results: OMT engendered a statistically significant increase of parasympathetic activity, as shown by High Frequency power (p < 0.001), expressed in normalized and absolute unit, and possibly decrease of sympathetic activity, as revealed by Low Frequency power (p < 0.01); results also showed a reduction of Low Frequency/High Frequency ratio (p < 0.001) and Detrended fluctuation scaling exponent (p < 0.05). Conclusions: Findings suggested that OMT can influence ANS activity increasing parasympathetic function and decreasing sympathetic activity, compared to sham therapy and control group. PMID:26300719

The 2015 American Thyroid Association guidelines recognize active surveillance as an alternative to immediate surgery in patients with papillary microcarcinomas (PMCs). As a way to incorporate active surveillance as one of the management options for patients with PMCs, we describe the development and initial testing of a tool to support conversations between clinicians and patients with PMCs considering treatment options. Thyroid Cancer Treatment Choice was developed using an iterative process based on the principles of interaction, design and participatory action research. To evaluate the impact of the tool on treatment choice, a prospective study was conducted in two thyroid cancer clinics in Seongnam-si and Seoul, South Korea: both clinics had the expertise to offer active surveillance as well as immediate surgery. One clinic was trained in the use of the conversation aid, while the other clinic continued to care for patients without access to the conversation aid. Between May 2016 and April 2017, 278 patients mostly women (n=220, 79%) were included in the study; 152 (53%) received care at the clinic using the conversation aid. Age, gender, and mean tumor size [6.6 mm (SD 1.6) and 6.5 mm (SD 1.9)] distributions were similar across clinics. Overall, 233 (84%) patients opted for active surveillance and 53 (16%) for thyroid surgery. Patients in the conversation aid group were more likely to choose active surveillance than the patients seen in the usual care clinic [relative risk (RR) = 1.16; 95% confidence interval (CI), 1.04 - 1.29]. Of all patients opting for active surveillance, more patients in the conversation aid group had thyroid cancer nodules > 5 mm than in the usual care group (81% vs. 67% P = 0.013). Thyroid Cancer Treatment Choice is an evidence-based tool that supports the presentation of treatment options for PMCs. Pilot testing suggests that this conversation tool increases acceptance of active surveillance, suggesting that this option is an acceptable and preferable alternative for informed patients. Further studies are warranted to confirm this finding.

Prior studies of hypochondriasis demonstrated benefits for pharmacotherapy and for cognitive-behavioral therapy (CBT). This study examined whether joint treatment offers additional benefit. Patients with DSM-IV hypochondriasis (N=195) were randomly assigned to one of four treatments-placebo, CBT, fluoxetine, or joint treatment with both fluoxetine and CBT. Evaluations assessed hypochondriasis, other psychopathology, adverse events, functional status, and quality of life. The primary analysis assessed outcome at week 24 among the intent-to-treat sample, with responders defined as having a 25% or greater improvement over baseline on both the Whiteley Index and a modified version of the Yale-Brown Obsessive Compulsive Scale for hypochondriasis (H-YBOCS-M). The Cochran-Armitage trend test assessed the hypothesized pattern of response: joint treatment > CBT or fluoxetine treatment > placebo treatment. The predicted pattern of response was statistically significant, as shown by the following responder rates: joint treatment group, 47.2%; single active treatment group, 41.8%; and placebo group, 29.6%. Responder rates for each active treatment were not significantly different from the rate for placebo. Secondary analyses of the Whiteley Index as a continuous measure revealed that, compared with placebo, fluoxetine (but not CBT) was significantly more effective at week 24 in reducing hypochondriasis and had a significantly faster rate of improvement over 24 weeks. Fluoxetine also resulted in significantly less anxiety and better quality of life than placebo. Dropout rates did not differ between groups, and treatment-emergent adverse events were evenly distributed. This study supports the safety, tolerance, and efficacy of fluoxetine for hypochondriasis. Joint treatment provided a small incremental benefit. Because approximately 50% of patients did not respond to the study treatments, new or more intensive approaches are needed.

Children with DCD have lower self-perceptions and are less physically active than typically developing children. The aim of this quasi-experimental study was to investigate whether an integrated perceived competence and motor intervention affects DCD children's motor performance, self-perceptions, and physical activity compared with a motor intervention only. The intervention group consisted of 20 children and the care-as-usual group consisted of 11 children, all aged 7-10 years. The perceived competence component of the intervention focused primarily on providing positive, specific, and progress feedback to enhance self-perceptions. We assessed children at baseline, after 12 treatment sessions (trial end-point), and at 3-month follow-up. Mixed linear models revealed no differences between the intervention and the care-as-usual group on any of the outcome measures. Children improved their motor performance and increased their perceived athletic competence, global self-esteem, and perceived motor competence after 12 treatment sessions. This improvement was maintained at 3-month follow-up. Motor task values and physical activity remained unchanged for all children. A perceived competence and motor intervention is as effective as care-as-usual in children with DCD. Future research should focus on improving physical activity in children with DCD. This is the first study that has investigated the effect of an integrated perceived competence and motor intervention (intervention group) on motor performance, self-perceptions, and physical activity compared with a motor intervention (care-as-usual group) in children with DCD. We made the perceived competence component explicit by providing positive, specific, and progress feedback to enhance children's self-perceptions. Also, this is one of the first studies that has investigated the effect after both 12 treatment sessions (trial end-point) and after 3 months of no intervention (3-month follow-up). We found no differences between the intervention and the care-as-usual group, but children improved their motor performance and increased (most) of their self-perceptions after 12 treatment sessions, while physical activity remained the same. The improvement was still present at the 3-month follow-up. We also benchmarked our results about self-perceptions and physical activity to a group of typically developing children. Self-perceptions in children with DCD had improved to the level of typically developing children after 12 treatment sessions, but their physical activity levels remained significantly lower. This result was the same at the 3-month follow-up, except for perceived athletic competence, which was lower in children with DCD at the 3-month follow-up. In accordance with previous intervention studies that have investigated children with DCD, we found large intra-group variability in the change in motor performance and self-perceptions in children with DCD. We argue that we need to better understand why some children with DCD improve and others do not after a motor intervention. Copyright © 2016 Elsevier Ltd. All rights reserved.

To examine the effect of a nonsteroidal antiinflammatory drug, carprofen, on the structure and metabolism of cartilage and subchondral bone in the experimental osteoarthritic (OA) canine model. Experimental Groups 1 and 2 received a sectioning of the anterior cruciate ligament (ACL) of the right stifle joint, and were administered carprofen (2.2 and 4.4 mg/kg/twice daily/po, respectively) for 8 weeks beginning 4 weeks postsurgery. Group 3 received ACL sectioning and no treatment. Group 4 was composed of unoperated normal dogs. Cartilage macroscopic lesions were assessed, and their histological severity was graded. Specimens of subchondral bones were fixed, decalcified, and stained with hematoxylin/eosin. The level of metalloprotease (MMP) activity in cartilage was measured. Osteoblast cells were prepared from the subchondral bone. The level of synthesis of osteoblast biomarkers (osteocalcin, alkaline phosphatase), as well as urokinase plasminogen activator (uPA) activity and insulin-like growth factor (IGF-1) in the culture medium, was estimated. Carprofen treatment decreased the width of osteophytes (p < 0.01), the size of cartilage lesions, and the histologic severity of cartilage lesions (p < 0.008). There was no difference in the levels of MMP activity in cartilage between OA and carprofen treated groups. In OA dogs, the subchondral bone plate was thinner and was the site of an extensive remodeling process with numerous lacunae. Dogs treated with carprofen showed a marked decrease in the remodeling activity with normal plate thickness, and subchondral bone morphology resembling that of normal dogs. Osteoblasts from untreated OA dogs showed slightly higher alkaline phosphatase activities and osteocalcin release that reverted back to normal upon carprofen treatment. Moreover, uPA activity and IGF-1 levels were increased in OA dogs and were significantly reduced in carprofen treated dogs. Under therapeutic conditions, treatment with carprofen could reduce the progression of early structural changes in experimental OA. Carprofen treatment also delays and/or prevents the abnormal metabolism of subchondral osteoblasts in this model. The hypothesis of a possible link between the protective effect of carprofen and its effect on subchondral bone is of interest in the context of therapeutic intervention.

Long-term patient adherence to osteoporosis treatment is poor despite proven efficacy. In this study, we aimed to assess the impact of active patient training on treatment compliance and persistence in patients with postmenopausal osteoporosis. In the present national, multicenter, randomized controlled study, postmenopausal osteoporosis patients (45-75 years) who were on weekly bisphosphonate treatment were randomized to active training (AT) and passive training (PT) groups and followed-up by 4 visits after the initial visit at 3 months interval during 12 months of the treatment. Both groups received a bisphosphonate usage guide and osteoporosis training booklets. Additionally, AT group received four phone calls (at 2(nd), 5(th), 8(th), and 11(th) months) and participated to four interactive social/training meetings held in groups of 10 patients (at 3(rd), 6(th), 9(th), and 12(th) months). The primary evaluation criteria were self-reported persistence and compliance to the treatment and the secondary evaluation criteria was quality life of the patients assessed by 41-item Quality of Life European Foundation for Osteoporosis (QUALEFFO-41) questionnaire. Of 448 patients (mean age 62.4±7.7 years), 226 were randomized to AT group and 222 were randomized to PT group. Among the study visits, the most common reason for not receiving treatment regularly was forgetfulness (54.9% for visit 2, 44.3% for visit 3, 51.6% for visit 4, and 43.8% for visit 5), the majority of the patients always used their drugs regularly on recommended days and dosages (63.8% for visit 2, 60.9% for visit 3, 72.1% for visit 4, and 70.8% for visit 5), and most of the patients were highly satisfied with the treatment (63.4% for visit 2, 68.9% for visit 3, 72.4% for visit 4, and 65.2% for visit 5) and wanted to continue to the treatment (96.5% for visit 2, 96.5% for visit 3, 96.9% for visit 4, and 94.4% for visit 5). QUALEFFO scores of the patients in visit 1 significantly improved in visit 5 (37.7±25.4 vs. 34.0±14.6, p<0.001); however, the difference was not significant between AT and PT groups both in visit 1 and visit 5. In conclusion, in addition to active training, passive training provided at the 1(st) visit did not improve the persistence and compliance of the patients for bisphosphonate treatment.

Drumming has been utilized among American Indian/Alaska Native (AI/AN) tribes for centuries to promote healing and self-expression. Drum-Assisted Recovery Therapy for Native Americans (DARTNA), currently under development, is a substance abuse treatment utilizing drumming as a core component. Focus groups were conducted to assist in the development of the DARTNA protocol. Feedback obtained from these focus groups will inform a subsequent pretest of DARTNA and an empirical study analyzing its effectiveness. Three focus groups were conducted among AIs/ANs with substance use disorders (n = 6), substance abuse treatment providers (n = 8), and a community advisory board (n = 4) to solicit feedback prior to a pretest of the DARTNA protocol. Overall, participants indicated that DARTNA could be beneficial for AIs/ANs with substance use disorders. Four overarching conceptual themes emerged across the focus groups: (1) benefits of drumming, (2) importance of a culture-based focus, (3) addressing gender roles in drumming activities, and (4) providing a foundation of common AI/AN traditions. The DARTNA protocol is a potentially beneficial and culturally appropriate substance abuse treatment strategy for AIs/ANs. In order to optimize the potential benefits of a substance abuse treatment protocol utilizing drumming for AIs/ANs, adequate attention to tribal diversity and gender roles is needed. Due to the shortage of substance abuse treatments utilizing traditional healing activities for AIs/ANs, including drumming, results from this study provide an opportunity to develop an intervention that may meet the unique treatment needs of AIs/ANs.

To observe the efficacy differences between acupoint catgut embedding combined with ginger-partitioned moxibustion and regular acupuncture on chronic fatigue syndrome (CFS) of spleen-kidney yang deficiency syndrome, and to explore its effects on T lymphocyte subsets and activity of NK cell. A total of 60 patients with CFS of spleen-kidney yang deficiency syndrome were randomly divided into a catgut embedding combined with ginger-partitioned moxibustion (CECGP) group and a regular acupuncture group, 30 cases in each one. The patients in the CECGP group were treated with acupoint catgut embedding combined with ginger-partitioned moxibustion; the acupoint catgut embedding was applied at Guanyuan (CV 4), Shenshu (BL 23), Pishu (BL 20), Zusanli (ST 36), Qihai (CV 6), once a week, while the ginger-partitioned moxibustion was applied at Guanyuan (CV 4), Qihai (CV 6) and Zusanli (ST 36), once every three days for consecutive one month. The patients in the regular acupuncture group were treated with regular acupuncture at Guanyuan (CV 4), Shenshu (BL 23), Pishu (BL 20), Zusanli (ST 36), Qihai (CV 6), once a day, 6 treatments per week (one day for rest) for consecutive one month. The clinical symptom scores, fatigue scale-14 (FS-14), fatigue assessment instrument (FAI), laboratory test results and total effective rate were compared between the two groups before and after treatment. (1) After treatment, the clinical symptom scores, FS-14 and FAI were reduced in the two groups (all P <0.05); after treatment, the clinical symptom scores, FS-14 and FAI in the CECGP group were significantly lower than those in the regular acupuncture group (all P <0.05). (2) After treatment, the CD 4 + /CD 8 + , natural killer cell% (NK%), CD 3 + %, CD% were all increased in the two groups (all +4 P <0.05); the CD 4 + /CD 8 + , CD 3 + %, CD% in the CECGP group were significantly higher than those in the regular acupuncture group (all P <0.05). (3) After treatment, the total effective rate was 96.7% (29/30) in the CECGP group, which was similar to 93.3% (28/30) in the regular acupuncture group ( P >0.05). The acupoint catgut embedding combined with ginger-partitioned moxibustion, which could effectively relieve the symptoms, regulate T lymphocyte subsets and the activity of NK cell, is an effective method for CFS of spleen-kidney yang deficiency syndrome.

Previous retrospective studies have shown that physical functioning in older cancer survivors is affected after treatment, yet prospective data are lacking. The aim of this study was to assess change in physical functioning in different age groups of patients with hormone receptor-positive breast cancer who were enrolled in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase III trial. Two physical parameters were assessed. Physical functioning was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire 1 year (T1) and 2 years (T2) after diagnosis. Physical activity was measured in metabolic equivalent of task (MET) hours/week at T1 and T2. Physical activity before diagnosis (T0) was assessed retrospectively at the T1 questionnaire. Patients were divided into three age groups: <60, 60-69, and ≥70 years. Decline in physical functioning was assessed using linear regression analysis. Differences in mean values of physical activity levels were calculated using repeated-measures one-way analysis of variance. A total of 431 patients were included for analysis. In all age groups, physical activity levels at T1 and T2 were significantly lower than prediagnostic physical activity levels (T0) (p < .001 for all age groups). Age ≥70 years was independently associated with decline in physical functioning between T1 and T2 (β = -4.62, 95% confidence interval -8.73 to -0.51, p = .028). Patients aged 70 years or older treated with breast surgery and adjuvant hormonal therapy did not improve between years 1 and 2 after diagnosis to the same extent as did younger patients. Although older patients constitute a large share of the breast cancer population, little is known about the effect and consequences of treatment of breast cancer in this specific age group. This study revealed that, unlike younger patients, older patients do not regain their physical abilities after surgical and adjuvant treatment for breast cancer. In older adults, the effect of treatment on physical functioning and independency could be more relevant than survival outcomes. Clinicians and older patients should be aware of the impact of treatment on physical functioning and prevent older patients from experiencing physical decline, which could lead to institutionalization and loss of independence. There is a need for age-specific guidelines that take into account the heterogeneity of the older population and for evidence-based treatment that focuses not only on cancer-specific outcomes but also on the consequences of treatment for physical and cognitive functioning and quality of life. ©AlphaMed Press.

The aim of the present study was to investigate the effect of streptozotocin-induced diabetes mellitus and lipoic acid treatment on serum paraoxonase-1 and paraoxonase-3 protein levels and paraoxonase, arylesterase and lactonase activities.36 rats were equally and randomly divided into 4 groups as control, lipoic acid, diabetes and diabetes+lipoic acid. To induce diabetes, a single dose of streptozotocin (40 mg/kg) was injected intraperitoneally to diabetes and diabetes+lipoic acid groups. Lipoic acid (10 mg/kg/day) was injected intraperitoneally for 14 days to lipoic acid and diabetes+lipoic acid groups. Serum PON1 and PON3 protein levels were measured by western blotting. Serum paraoxonase, arylesterase and lactonase activities were determined by the measuring initial rate of substrate (paraoxon, phenylacetate and dihydrocoumarin) hydrolysis.Streptozotocin-induced diabetes mellitus caused a significant decrease whereas lipoic acid treatment caused a significant increase in serum PON1 and PON3 protein levels and paraoxonase, arylesterase and lactonase activities. The increase percent of serum PON3 protein was higher than that of serum PON1 protein and the increase percent of serum lactonase activity was higher than that of serum paraoxonase and arylesterase activities in diabetes+lipoic acid group.We can report that, like PON1 protein, PON3 protein and actually its lactonase activity may also have a role as an antioxidant in diabetes mellitus and lipoic acid treatment may be useful for the prevention of the atherosclerotic complications of diabetes by increasing serum PON1 and PON3 protein levels and serum enzyme activities. © Georg Thieme Verlag KG Stuttgart · New York.

The objective of this study was to evaluate the effect of Moquiniastrum polymorphum ssp floccosum ethanolic extract (MPEE) on 1,2 dimethylhydrazine (DMH)-induced colorectal carcinogenesis in mice. Forty-two male Swiss mice (Mus musculus) were subdivided into six groups (N = 7/group): negative control, DMH, MPEE, pre-treatment, simultaneous, and post-treatment. Results showed that MPEE has antigenotoxic potential on the tested protocols pre- and silmultaneous treatment, and the percent damage reductions (%DRs) were 81.88 and 93.12%, respectively. The micronucleus test demonstrated that MPEE has great antimutagenic activity, with %DRs higher than 77.09 in the associated groups. The aberrant crypt focus assay demonstrated anticarcinogenic potential of MPEE as the associated groups showed %DRs that ranged from 62.13 to 95.14%. The study shows that MPEE is nontoxic and has chemopreventive and anticarcinogenic activity, thus it may prove to be a promising medicinal plant in view of its demonstrated properties.

We investigated the effect of phytosterol (PS) in regard to liver damage induced by 4-nitrophenol (PNP). Twenty rats were randomly divided into four groups (Control, PS, PNP, and PNP+PS). The PS and PNP+PS groups were pretreated with PS for one week. The PNP and PNP+PS groups were injected subcutaneously with PNP for 28 days. The control group received a basal diet and was injected with vehicle alone. Treatment with PS prevented the elevation of the total bilirubin levels, as well as an increase in serum alkaline transaminase and aspartate transaminase, which are typically caused by PNP-induced liver damage. Histopathologically showed that liver damage was significantly mitigated by PS treatment. However, there was no significant change in antioxidant enzyme activities, and the Nrf2-antioxidant system was not activated after treatment with PS. These results suggest that PS could mitigate liver damage induced by PNP, but does not enhance antioxidant capacity. Copyright © 2015 Elsevier B.V. All rights reserved.

Cardiopulmonary bypass (CPB) surgery, despite heparin administration, elicits activation of coagulation system resulting in coagulopathy. Anti-inflammatory effects of steroid treatment have been demonstrated, but its effects on coagulation system are unknown. The primary objective of this study is to assess the effects of methylprednisolone on coagulation function by evaluating thrombin generation, fibrinolysis, and platelet activation in high-risk patients undergoing cardiac surgery with CPB. The Steroids In caRdiac Surgery study is a double-blind, randomized, controlled trial performed on 7507 patients worldwide who were randomized to receive either intravenous methylprednisolone, 250 mg at anesthetic induction and 250 mg at initiation of CPB (n = 3755), or placebo (n = 3752). A substudy was conducted in 2 sites to collect blood samples perioperatively to measure prothrombin fragment 1.2 (PF1+2, thrombin generation), plasmin-antiplasmin complex (PAP, fibrinolysis), platelet factor 4 (PF4 platelet activation), and fibrinogen. Eighty-one patients were enrolled in the substudy (37 placebo vs 44 in treatment group). No difference in clinical outcome was detected, including postoperative bleeding and need for blood products transfusion. All patients showed changes of all plasma biomarkers with greater values than baseline in both groups. This reaction was attenuated significantly in the treatment group for PF1.2 (P = 0.040) and PAP (P = 0.042) values at the first intraoperative measurement. No difference between groups was detected for PF4. Methylprednisolone treatment attenuates activation of coagulation system in high-risk patients undergoing CPB surgery. Reduction of thrombin generation and fibrinolysis activation may lead to reduced blood loss after surgery. Copyright © 2017 Elsevier Inc. All rights reserved.

To determine the effects of Lactobacillus acidophilus NCFM on irritable bowel syndrome (IBS) symptoms and quality of life (QoL). In this randomized triple-blind trial, adult IBS volunteers who were recruited according to Rome III criteria received 10 9 or 10 10 colony-forming units of NCFM or placebo daily for 12 wk. IBS Symptom Severity Score (IBS-SSS), which constituted the primary outcome, and secondary outcomes, including individual IBS symptoms, IBS-related QoL questionnaire, anxiety and depression, defecation frequency, and stool consistency, were assessed at baseline at the end of the 8-wk run-in period, after 4 and 12 wk of intervention, and after a 4-wk washout. A total of 340 of 391 randomized volunteers completed the trial. IBS-SSS improved over 12 wk of treatment in all treatment groups, decreasing by a mean ± SD of 44.0 ± 80.2, 50.8 ± 82.4, and 48.3 ± 72.2 in the placebo, active low-dose, and active high-dose groups, respectively. Similarly, secondary outcomes did not differ between treatment groups. However, in a post hoc analysis of volunteers with moderate to severe abdominal pain at baseline (VAS > 35/100), the treatment significantly reduced the sensation of abdominal pain. Pain scores fell by 20.8 ± 22.8, 29.4 ± 17.9, and 31.2 ± 21.9 in the placebo, active low-dose, and active high-dose groups, respectively ( P value for placebo vs combined active doses = 0.0460). NCFM alleviates moderate to severe abdominal pain, consistent with earlier observations of this strain mitigating visceral pain through increased analgesic receptor expression.

To examine the efficacy of a Cognitive-Functional (Cog-Fun) intervention for children with ADHD. Random allocation of 107 children to study or control groups preceded 10 parent-child weekly Cog-Fun sessions emphasizing executive strategy training in games and daily activities. Controls received treatment after crossover. Study participants were followed up 3 months post-treatment. Outcomes included parent/teacher ratings of executive functions, ADHD symptoms, and parent ratings of quality of life. Eight children withdrew prior to treatment. All children in both groups who began treatment completed it. Mixed effects ANOVA revealed significant Time × Group interaction effects on all parent-reported outcomes. Treatment effects were moderate to large, replicated after crossover in the control group and not moderated by medication. Parent-reported treatment gains in the study group were maintained at follow-up. No significant Time × Group interaction effects were found on teacher outcomes. Cog-Fun occupational therapy (OT) intervention shows positive context-specific effects on parent, but not teacher, ratings. © The Author(s) 2016.

To explore the new mechanisms of tamoxifen (TAM) in the treatment for patients with idiopathic oligoasthenospermia-antioxidation. In a prospective, randomized, controlled clinical trial, 120 cases of idiopathic oligoasthenospermia were enrolled and randomly assigned to the indomethacin group (n = 60) treated with indomethacin (25 mg, bid) and TAM group (n = 60) treated with TAM (10 mg, bid) for 3 months. Before and after treatment, we evaluated semen parameters, serum malondialdehyde (MDA) and total antioxidant capacity (TAC), seminal plasma MDA and TAC, spermatozoa intracellular reactive oxygen species (ROS), sperm succinate dehydrogenase (SDH) activity, sperm mitochondrial membrane potential (MMP), and sperm adenosine triphosphate (ATP) content. The independent t test and one-way repeated measures analysis of variance were used to compare the variables between and within two groups. In the indomethacin group, the percentage of progressive motile sperms, total motility, sperm MMP, and ATP content were increased significantly after 3-month treatment (P < 0.05). In the TAM group, total sperm count, sperm concentration, the percentage of progressive motile sperms, total motility, serum and seminal plasma TAC, sperm MMP, and ATP content were significantly improved or increased (P < 0.05), while spermatozoa intracellular ROS was significantly decreased (P < 0.05). Compared to the indomethacin group, TAM treatment showed better improvement in total sperm count, sperm concentration, serum TAC, seminal plasma TAC, spermatozoa intracellular ROS, and sperm SDH activity. TAM treatment can significantly improve sperm quality, which is achieved through alleviating oxidative stress, improving sperm mitochondrial functionality, and subsequently increasing sperm motility.

We assessed the efficacy and safety of direct oral anticoagulants (DOACs) for the treatment of deep venous thrombosis (DVT) in the chronic phase through comparison with conventional warfarin therapy.A total of 807 consecutive patients who were diagnosed with having DVT in the chronic phase were included (484 patients to warfarin therapy and 323 patients to DOAC therapy). The condition of leg veins was assessed 3 to 6 months after starting the therapies by ultrasound examination. Major bleeding and mortality during the therapies were followed-up.There was no significant difference between the two groups in the thrombosis improvement rate (DOAC group: 91.2% versus warfarin group: 88.9%). There was no significant difference between the two groups in major bleeding (DOAC group: 1.8% versus warfarin group: 1.8%). In patients with active cancer, the DOAC group had a borderline higher thrombosis improvement rate than the warfarin group (92.1% versus 80.0%, P = 0.05). The proportion of major bleeding in the patients with active cancer was slightly higher in the warfarin group than in the DOAC group (4.3% versus 2.8%; P = 0.71). Active cancer was not an independent risk factor for major bleeding and recurrence in the DOAC group (OR 2.68, 95% CI 0.51-14.1; P = 0.24 and OR 0.65, 95% CI 0.20-2.07; P = 0.47).In treatment using oral anticoagulants for DVT in the chronic phase, DOACs exhibited equal efficacy and safety as warfarin did. Particularly DOACs appear to be an attractive therapeutic option for cancer-associated DVT in chronic phase, with relatively low anticipated rates of recurrence and major bleeding.

The comparative effectiveness of treatments for prostate cancer that is detected by prostate-specific antigen (PSA) testing remains uncertain. We compared active monitoring, radical prostatectomy, and external-beam radiotherapy for the treatment of clinically localized prostate cancer. Between 1999 and 2009, a total of 82,429 men 50 to 69 years of age received a PSA test; 2664 received a diagnosis of localized prostate cancer, and 1643 agreed to undergo randomization to active monitoring (545 men), surgery (553), or radiotherapy (545). The primary outcome was prostate-cancer mortality at a median of 10 years of follow-up. Secondary outcomes included the rates of disease progression, metastases, and all-cause deaths. There were 17 prostate-cancer-specific deaths overall: 8 in the active-monitoring group (1.5 deaths per 1000 person-years; 95% confidence interval [CI], 0.7 to 3.0), 5 in the surgery group (0.9 per 1000 person-years; 95% CI, 0.4 to 2.2), and 4 in the radiotherapy group (0.7 per 1000 person-years; 95% CI, 0.3 to 2.0); the difference among the groups was not significant (P=0.48 for the overall comparison). In addition, no significant difference was seen among the groups in the number of deaths from any cause (169 deaths overall; P=0.87 for the comparison among the three groups). Metastases developed in more men in the active-monitoring group (33 men; 6.3 events per 1000 person-years; 95% CI, 4.5 to 8.8) than in the surgery group (13 men; 2.4 per 1000 person-years; 95% CI, 1.4 to 4.2) or the radiotherapy group (16 men; 3.0 per 1000 person-years; 95% CI, 1.9 to 4.9) (P=0.004 for the overall comparison). Higher rates of disease progression were seen in the active-monitoring group (112 men; 22.9 events per 1000 person-years; 95% CI, 19.0 to 27.5) than in the surgery group (46 men; 8.9 events per 1000 person-years; 95% CI, 6.7 to 11.9) or the radiotherapy group (46 men; 9.0 events per 1000 person-years; 95% CI, 6.7 to 12.0) (P<0.001 for the overall comparison). At a median of 10 years, prostate-cancer-specific mortality was low irrespective of the treatment assigned, with no significant difference among treatments. Surgery and radiotherapy were associated with lower incidences of disease progression and metastases than was active monitoring.

To compare the intensity of pain and duration of return to normal activity in patients with rib fractures treated with surgical stabilization with plating versus conventional treatment modalities. This study was conducted over a 12 month period. Patients with rib fractures were assessed by numerical pain scale. Patients having pain scale less than 5 were excluded from study. Patients having pain scale of 5 or more than 5 were treated with conventional treatment for next 10 days. On 11th day patients were again assessed by numerical pain scale and patients having score less than 5 were excluded from study. Patients having pain scale of 5, 6, and 7 were treated with conventional treatment and patients having pain scale of 8, 9, and 10 were selected for operative management. Operative and control group were compared on basis of intensity of pain and duration of return to normal activity. Follow up was done on 5, 15, and 30 post operative day. There was less pain in operative group as compared to control group. Mean rib fracture pain in operative group was 9.15, 2.31, 1.12 as compared to 6.25, 5.96, 4.50 in control group on 5, 15 and 30 post operative days. Also there was early return to normal activity in operative group. Surgical stabilization of rib fracture, an underutilized intervention is better than conventional conservative management in terms of both, decrease in intensity of pain and early return to normal activity.

Cue-induced craving plays an important role in relapse, and the neural correlates of cue-induced craving have been elucidated using fMRI. This study examined the utility of real-time fMRI (rtfMRI) neurofeedback to strengthen self-regulation of craving-related neural activation and cue-reactivity in cigarette smokers. Nicotine-dependent smokers were randomized to rtfMRI neurofeedback or to a no-feedback control group. Participants completed 3 neuroimaging visits. Within each visit, an initial run during which smoking-related cues were used to provoke craving, an individualized craving-related region of interest (ROI) in the prefrontal cortex or anterior cingulate cortex was identified. In the rtfMRI group, activity from the ROI was fed back via a visual display during 3 subsequent runs while participants were instructed to reduce craving during cue exposure. The control group had an identical experience with no feedback provided. Forty-four nicotine-dependent smokers were recruited to participate in our study; data from the 33 participants who completed a 1-week follow-up visit were included in the analysis. Subjective craving ratings and cue-induced brain activation were lower in the rtfMRI group than in the control group. As participants were not seeking treatment, clinical outcomes are lacking. Nicotine-dependent smokers receiving rtfMRI feedback from an individualized ROI attenuated smoking cue-elicited neural activation and craving, relative to a control group. Further studies are needed in treatment-seeking smokers to determine if this intervention can translate into a clinically meaningful treatment modality.

In the present study, we investigated the efficiency of rosmarinic acid (RA) in preventing the alteration of oxidative parameters in the liver and kidney of diabetic rats induced by streptozotocin (STZ). The animals were divided into six groups (n = 8): control, ethanol, RA 10 mg/kg, diabetic, diabetic/ethanol, and diabetic/RA 10 mg/kg. After 3 weeks of treatment, we found that TBARS levels in liver and kidney were significantly increased in the diabetic/saline group and the administration of RA prevented this increase in the liver and kidney (P < 0.05). Diabetes caused a significant decrease in the activity of superoxide dismutase (SOD) and catalase (CAT) in the diabetes/saline group (P < 0.05). However, the treatment with 10 mg/kg RA (antioxidant) prevented this alteration in SOD and CAT activity in the diabetic RA group (P < 0.05). In addition, RA reverses the decrease in ascorbic acid and non-protein-thiol (NPSH) levels in diabetic rats. The treatment with RA also prevented the decrease in the Delta-aminolevulinic acid dehydratase (ALA-D) activity in the liver and kidney of diabetic rats. Furthermore, RA did not have any effect on glycemic levels. These results indicate that RA effectively reduced the oxidative stress induced by STZ, suggesting that RA is a potential candidate for the prevention and treatment of pathological conditions in diabetic models.

To investigate the protective effect of the active form of vitamin D3, 1,25-(OH)2D3, on macrovasculopathy in rats with type 2 diabetes mellitus (T2DM), 8-week-old male Sprague-Dawley rats were randomly divided into control group, T2DM group, and treatment group. The T2DM model was established after 6 weeks by administering an intraperitoneal injection of streptozotocin (30 mg/kg). 1,25-(OH)2D3 was administered by gavage to rats in the treatment group, and an equal volume of peanut oil was administered to rats in the T2DM group. Fasting plasma glucose (FPG), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C) cholesterols were measured in all rats. The morphology of the thoracic aorta was examined, and the expression of tumor necrosis factor alpha (TNF-α), endothelin (ET), endothelial nitric oxide synthase (eNOS), CD54, and CD106 in the thoracic aorta was determined by immunohistochemistry. The expression of FPG, TG, TC, and LDL-C in rats from the T2DM and treatment groups was significantly elevated compared with rats from the control group (P < 0.05). Compared with that in control group, the expression of TNF-α, ET, eNOS, and CD106 was significantly upregulated in the T2DM group and the treatment group, while the expression of CD54 was increased only in the T2DM group (P < 0.05). Moreover, the levels of TNF-α, CD54, and CD106 in rats from the treatment group were lower than those in the T2DM group (P < 0.05). These data suggest that 1,25-(OH)2D3 may protect the macrovessels from injury in T2DM rats by inhibiting the expression of TNF-α, CD54, and CD106.

Climate change generally and global warming specifically have become a common feature of the daily news. Due to widespread recognition of the adverse consequences of climate change on human lives, concerted societal effort has been taken to address it (e.g. by means of the science curriculum). This study was designed to test the effect that child-centred, 5E learning cycle-based climate change activities would have over more traditional teacher-centred activities on Malaysian Year 5 primary students (11 years). A quasi-experimental design involving a treatment (n = 55) and a group representing typical teaching method (n = 60) was used to measure the effectiveness of these activities on (a) increasing children's knowledge about global warming; (b) changing their attitudes to be more favourable towards the environment and (c) identify the relationship between knowledge and attitude that exist in this study. Statistically significant differences in favour of the treatment group were detected for both knowledge and environmental attitudes. Non-significant relationship was identified between knowledge and attitude in this study. Interviews with randomly selected students from treatment and comparison groups further underscore these findings. Implications are discussed.

Physical therapy is recommended for the management of axial spondyloarthritis (axSpA) and flexibility exercises have traditionally been the main focus. Cardiovascular (CV) diseases are considered as a major health concern in axSpA and there is strong evidence that endurance and strength exercise protects against CV diseases. Therefore, the aim of this study was to investigate the efficacy of high intensity endurance and strength exercise on disease activity and CV health in patients with active axSpA. In a single blinded randomized controlled pilot study the exercise group (EG) performed 12 weeks of endurance and strength exercise while the control group (CG) received treatment as usual. The primary outcome was the Ankylosing Spondylitis (AS) Disease Activity Score (ASDAS). Secondary outcomes included patient reported disease activity (Bath AS Disease Activity Index [BASDAI]), physical function (Bath AS Functional Index [BASFI]), and CV risk factors measured by arterial stiffness (Augmentation Index [Alx]) and Pulse Wave Velocity [PWV]), cardiorespiratory fitness (VO2 peak) and body composition. ANCOVA on the post intervention values with baseline values as covariates was used to assess group differences, and Mann Whitney U-test was used for outcomes with skewed residuals. Twenty-eight patients were included and 24 (EG, n = 10, CG, n = 14) completed the study. A mean treatment effect of -0.7 (95%CI: -1.4, 0.1) was seen in ASDAS score. Treatment effects were also observed in secondary outcomes (mean group difference [95%CI]): BASDAI: -2.0 (-3.6, -0.4), BASFI: -1.4 (-2.6, -0.3), arterial stiffness (estimated median group differences [95% CI]): AIx (%): -5.3 (-11.0, -0.5), and for PVW (m/s): -0.3 (-0.7, 0.0), VO2 peak (ml/kg/min) (mean group difference [95%CI]: 3.7 (2.1, 5.2) and trunk fat (%): -1.8 (-3.0, -0.6). No adverse events occurred. High intensity exercise improved disease activity and reduced CV risk factors in patients with active axSpA. These effects will be further explored in a larger trial.

Pulsed radiofrequency (PRF) is effective in the treatment of neuropathic pain in clinical practice. Its application to sites proximal to nerve injury can inhibit the activity of extra-cellular signal-regulated kinase (ERK) for up to 28 days. The spared nerve injury (SNI)+ immPRF group (immediate exposure to PRF for 6 min after SNI) exhibited a greater anti-allodynic effect compared with the control group (SNI alone) or the SNI + postPRF group (application of PRF for 6 min on the 14th day after SNI). Insulin-like growth factor 2 (IGF2) was selected using microarray assays and according to web-based gene ontology annotations in the SNI + immPRF group. An increase in IGF2 and activation of ERK1/2 were attenuated by the immPRF treatment compared with an SNI control group. Using immunofluorescent staining, we detected co-localized phosphorylated ERK1/2 and IGF2 in the dorsal horn regions of rats from the SNI group, where the IGF2 protein predominantly arose in CD11b- or NeuN-positive cells, whereas IGF2 immunoreactivity was not detected in the SNI + immPRF group. Taken together, these results suggest that PRF treatment immediately after nerve injury significantly inhibited the development of neuropathic pain with a lasting effect, most likely through IGF2 down-regulation and the inhibition of ERK1/2 activity primarily in microglial cells.

The aim of this randomized double-blind study was to evaluate in healthy adult subjects, with functional magnetic resonance imaging (fMRI), long lasting changes in brain activation patterns following administration of a single, 250 milliseconds pulse emitted with radio-electric asymmetric conveyer (REAC) technology in the Wi-Fi bands. The REAC impulse was not administered during the scan, but after this, according to a protocol that has previously been demonstrated to be effective in improving motor control and postural balance, in healthy subjects and patients. The study was conducted on 33 healthy volunteers, performed with a 1.5 T unit while operating a motor block task involving cyclical and alternating flexion and extension of one leg. Subsequently subjects were randomly divided into a treatment and a sham treatment control group. Repeated fMRI examinations were performed following the administration of the REAC pulse or sham treatment. The Treated group showed cerebellar and ponto-mesencephalic activation components that disappeared in the second scan, while these activation components persisted in the Sham group. This study shows that a very weak signal, such as 250 milliseconds Wi-Fi pulse, administered with REAC technology, could lead to lasting effects on brain activity modification.

To evaluate the efficacy of botulinum toxin type A injection to cause orbicularis eyelid muscle paralysis to improve dry eye signs and symptoms. A prospective, randomized, comparative eye-to-eye and interventional study was performed. Patients with dry eye symptoms and positive fluorescein corneal staining were included. Randomly one eyelid received a subcutaneous injection of botulinum toxin in the medial orbicularis muscle portion of the lower eyelid, and the other eye received placebo. The subjective evaluation was achieved with a questionnaire assessing symptoms, quality of vision and ocular comfort level. The objective evaluation included the measurement of the tear film break-up time (TBUT), Schirmer's test and corneal and conjunctival staining. Twenty patients were included with a mean age of 59.5 years. Two weeks after the botulinum toxin injection, all patients showed a decrease in the horizontal movement of the lower eyelid when blinking. The eyes in the active treatment group showed better scores compared with the sham group in four symptoms 4 weeks after the treatment. The TBUT was higher at 1 and 3 months in the active treatment group. The corneal and conjunctival staining were significantly lower in the active treatment group at 1 and 3 months, and the Schirmer's test showed better measurements in the same group at 2 weeks, 1 month and 3 months. There were no adverse events reported. The injection of botulinum toxin A in the medial part of the lower eyelid is an effective and safe procedure that temporally improves some of the signs and symptoms of patients with dry eye. © 2016 Acta Ophthalmologica Scandinavica Foundation.

Pre-clinical and clinical studies in cocaine addiction highlight alterations in the striatal dopaminergic reward system that subserve maintenance of cocaine use. Using an instrumental conditioning paradigm with monetary reinforcement, we studied striatal functional alterations in long-term abstinent cocaine-dependent patients and striatal functioning as a function of abstinence and treatment duration. Eighteen patients and 20 controls underwent functional magnetic resonance imaging during a Monetary Incentive Delay task. Region of interest analyses based on masks of the dorsal and ventral striatum were conducted to test between-group differences and the functional effects in the cocaine group of time (in months) with no more than two lapses from the first time patients visited the clinical service to seek treatment at the scanning time (duration of treatment), and the functional effects of the number of months with no lapses or relapses at the scanning session time (length of abstinence). We applied a voxel-wise and a cluster-wise FWE-corrected level (pFWE) at a threshold of P < 0.05. The patient group showed lower activation in the right caudate during reward anticipation than the control group. The regression analyses in the patients group revealed a positive correlation between duration of treatment and brain activity in the left caudate during reward anticipation. Likewise, length of abstinence negatively correlated with brain activity in the bilateral nucleus accumbens during monetary outcome processing. In conclusion, caudate and nucleus accumbens show a different brain response pattern to non-drug rewards during cocaine addiction, which can be modulated by treatment success. © 2013 The Authors, Addiction Biology © 2013 Society for the Study of Addiction.

Menorrhagia is a common problem, yet evidence to inform decisions about therapy is limited. In a pragmatic, multicenter, randomized trial, we compared the levonorgestrel-releasing intrauterine system (levonorgestrel-IUS) with usual medical treatment in women with menorrhagia who presented to their primary care providers. We randomly assigned 571 women with menorrhagia to treatment with levonorgestrel-IUS or usual medical treatment (tranexamic acid, mefenamic acid, combined estrogen-progestogen, or progesterone alone). The primary outcome was the patient-reported score on the Menorrhagia Multi-Attribute Scale (MMAS) (ranging from 0 to 100, with lower scores indicating greater severity), assessed over a 2-year period. Secondary outcomes included general quality-of-life and sexual-activity scores and surgical intervention. MMAS scores improved from baseline to 6 months in both the levonorgestrel-IUS group and the usual-treatment group (mean increase, 32.7 and 21.4 points, respectively; P<0.001 for both comparisons). The improvements were maintained over a 2-year period but were significantly greater in the levonorgestrel-IUS group than in the usual-treatment group (mean between-group difference, 13.4 points; 95% confidence interval, 9.9 to 16.9; P<0.001). Improvements in all MMAS domains (practical difficulties, social life, family life, work and daily routine, psychological well-being, and physical health) were significantly greater in the levonorgestrel-IUS group than in the usual-treatment group, and this was also true for seven of the eight quality-of-life domains. At 2 years, more of the women were still using the levonorgestrel-IUS than were undergoing the usual medical treatment (64% vs. 38%, P<0.001). There were no significant between-group differences in the rates of surgical intervention or sexual-activity scores. There were no significant differences in serious adverse events between groups.

Low-level laser irradiation (LLLI) can enhance stem cell (SC) activity by increasing migration and proliferation. This study investigated the effects of LLLI on proliferation, enzymatic activity, and growth factor production in human umbilical cord mesenchymal SCs (hUC-MSCs) as well as the underlying mechanisms. hUC-MSCs were assigned to a control group (non-irradiation group) and three LLLI treatment groups (635 nm group, 808 nm group, and 635/808 nm group). Laser power density and energy density of 20 mW/cm2 and 12 J/cm2, respectively, were used for each experiment. The proliferation rate was higher in the 635 nm as compared to the other groups. LLLI at 808 nm did not induce cell proliferation. ROS levels in cells exposed to 635, 808, and 635/808 nm radiation were increased by 52.81%, 26.89%, and 21.15%, respectively, relative to the control group. CAT, tGPx, and SOD activity was increased. LLLI at 808 nm increased the levels of IL-1, IL-6, and NFκB but not VEGF. LLLI improved hUC-MSCs function and increased antioxidant activity. Dual-wavelength LLLI had more potent effects on hUC-MSCs than single-wavelength treatment. LLLI has potential applications in the preconditioning of hUC-MSCs in vitro prior to transplantation, which could improve the regenerative capacity of cells.

To explore the effects of pre versus post ischemic treatment with metformin after global cerebral ischemia in rats. Male Wister rats underwent forebrain ischemia by bilateral common carotid artery occlusion for 17 min. Metformin (200 mg/kg) or vehicle was given orally by gavage for 7-14 days. Rats were divided into: control, metformin pre-treatment, metformin post-treatment and metformin pre and post continuous treatment groups. Cerebral infarct size, histopathology, myeloperoxidase and serum malondialdehyde were measured 7 days after ischemia. Histopathological analysis showed that metformin pre-treatment significantly decreased leukocyte infiltration, myeloperoxidase activity and also malondialdehyde level. Metformin pre-treatment and metformin post-treatment reduced infarct size compared with the control group, but it was not significant in the pre and post continuous treatment group. Our findings suggest that pre-treatment with metformin in comparison with post-treatment in experimental stroke can reduce the extent of brain damage and is more neuroprotective at least in part by inhibiting oxidative stress and inflammation.

AIM: To investigate the anti-oxidative and anti-fibrotic effects of aloe vera in patients with liver fibrosis. METHODS: Aloe vera high molecular weight fractions (AHM) were processed by patented hyper-dry system in combination of freeze-dry technique with microwave and far infrared-ray radiation. Fifteen healthy volunteers as the control group and 40 patients were included. The patients were randomly subdivided into two equal groups: the conventional group was treated with placebo (starch), and AHM group was treated with 0.15 gm/d AHM, both for 12 consecutive weeks. The patients were investigated before and after treatment. Serum activity of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), hyaluronic acid (HA), transforming growth factor-β (TGF-β) and matrixmetalloproteinase-2 (MMP-2) were determined. The reduced glutathione (GSH) and malondialdehyde (MDA) levels in liver were assayed and the expression of hepatic α-smooth muscle actin (α-SMA) was identified by immunohistochemistry. RESULTS: At the start of the study, the hematoxylin and eosin staining revealed fibro-proliferated bile ductules, thick fibrous septa and dense inflammatory cellular infiltration in the patients before treatment. The use of AHM for 12 wk significantly ameliorated the fibrosis, inhibited the inflammation, and resulted in minimal infiltration and minimal fibrosis compared to the conventional group. The enzyme activities of the liver (ALT, AST and ALP) were attenuated after treatment in both groups, and the decrease in the AHM group was more significant as compared with the conventional group. Similar to the AST, the MDA levels were significantly higher before treatment, and were attenuated after treatment in both groups. In contrast, the hepatic glutathione content in the patients were decreased significantly in the AHM group compared to the controls. The serum levels of the fibrosis markers (HA, TGF-β and MMP-2) were also reduced significantly after treatment. The expression of α-SMA was modified in patients before and after treatment as compared with the normal controls. In the conventional group, there was only thin and incomplete parenchymal α-SMA positive septum joining the thickened centrilobular veins, while in the AHM group, few α-SMA positive cells were present in sinusoid and lobule after treatment. CONCLUSION: Oral supplementation with AHM could be helpful in alleviating the fibrosis and inflammation of hepatic fibrosis patients. PMID:22563189

Depression is associated with interpersonal difficulties related to abnormalities in affective facial processing. To map brain systems activated by sad facial affect processing in patients with depression and to identify brain functional correlates of antidepressant treatment and symptomatic response. Two groups underwent scanning twice using functional magnetic resonance imaging (fMRI) during an 8-week period. The event-related fMRI paradigm entailed incidental affect recognition of facial stimuli morphed to express discriminable intensities of sadness. Participants were recruited by advertisement from the local population; depressed subjects were treated as outpatients. We matched 19 medication-free, acutely symptomatic patients satisfying DSM-IV criteria for unipolar major depressive disorder by age, sex, and IQ with 19 healthy volunteers. Intervention After the baseline assessment, patients received fluoxetine hydrochloride, 20 mg/d, for 8 weeks. Average activation (capacity) and differential response to variable affective intensity (dynamic range) were estimated in each fMRI time series. We used analysis of variance to identify brain regions that demonstrated a main effect of group (depressed vs healthy subjects) and a group x time interaction (attributable to antidepressant treatment). Change in brain activation associated with reduction of depressive symptoms in the patient group was identified by means of regression analysis. Permutation tests were used for inference. Over time, depressed subjects showed reduced capacity for activation in the left amygdala, ventral striatum, and frontoparietal cortex and a negatively correlated increase of dynamic range in the prefrontal cortex. Symptomatic improvement was associated with reduction of dynamic range in the pregenual cingulate cortex, ventral striatum, and cerebellum. Antidepressant treatment reduces left limbic, subcortical, and neocortical capacity for activation in depressed subjects and increases the dynamic range of the left prefrontal cortex. Changes in anterior cingulate function associated with symptomatic improvement indicate that fMRI may be a useful surrogate marker of antidepressant treatment response.

A randomized controlled trial was performed to study the efficacy of Syn-Ergel with an active placebo in the treatment of heartburn of pregnancy in ninety-two patients completing 7 days of therapy. Syn-Ergel was significantly better (p less than 0.001) in all groups of pre-treatment pain severity in relieving the symptoms, and had a longer duration of action, than the active placebo. Complete relief of pain was achieved in 79.5% of Syn-Ergel treatments with a further 10% of treatments resulting in marked easing of discomfort at 1 hour following administration. The corresponding figures for the 'active placebo' were 56% and 20%. The combination of an antacid and a protective mucosal coating agent would appear to be a useful approach in the treatment of heartburn of pregnacy.

Epidemiological studies suggest that compared with the general population, mood disorders are up to 4.7 times more prevalent in substance dependent samples. Comorbid substance use disorder (SUD) and depression has been associated with a more severe and protracted illness course and poorer treatment outcomes. Despite this, the development and assessment of behavioural interventions for treating depression among individuals with SUDs have received little empirical attention. Behavioural Activation Treatment for Depression (BATD-R) is an empirically supported treatment for depression that has shown some efficacy among substance users. This paper describes the study protocol of a parallel, single blind, randomised controlled trial to determine the efficacy and feasibility of a modified version of the BATD-R (Activate) in reducing symptoms of depression and substance dependence among individuals in residential rehabilitation (RR) and opioid substitution therapy (OST). A sample of approximately 200 individuals with depressive symptomatology in treatment for SUD will be recruited from RR and OST services in New South Wales, Australia. Dynamic random allocation following minimisation methodology will be used to assign participants to one of two groups. The control group will receive treatment as usual (TAU), which will be the model of care provided in accordance with standard practice at participating RR and OST services. The intervention group will receive Activate, comprising 10 individual 60-min therapy sessions with a psychologist employed on the research team, in addition to TAU. Data collection will occur at baseline (pre-intervention), and 3-months and 12-months post baseline. The association between depression and substance dependence has been well documented, yet practical and effective treatments are scarce. The findings of the present study will contribute significantly to understanding the types of programs that are effective in treating this comorbidity. This trial is registered with the Australian and New Zealand Clinical Trials registry, ACTRN12613000876796 . Registered on 7 August, 2013.

There is strong evidence of sex differences in mental rotation tasks. Transsexualism is an extreme gender identity disorder in which individuals seek cross-gender treatment to change their sex. The aim of our study was to investigate if male-to-female (MF) and female-to-male (FM) transsexuals receiving cross-sex hormonal treatment have different patterns of cortical activation during a three-dimensional (3D) mental rotation task. An fMRI study was performed using a 3-T scan in a sample of 18 MF and 19 FM under chronic cross-sex hormonal treatment. Twenty-three males and 19 females served as controls. The general pattern of cerebral activation seen while visualizing the rotated and non-rotated figures was similar for all four groups showing strong occipito-parieto-frontal brain activation. However, compared to control males, the activation of MF transsexuals during the task was lower in the superior parietal lobe. Compared to control females, MF transsexuals showed higher activation in orbital and right dorsolateral prefrontal regions and lower activation in the left prefrontal gyrus. FM transsexuals did not differ from either the MF transsexual or control groups. Regression analyses between cerebral activation and the number of months of hormonal treatment showed a significant negative correlation in parietal, occipital and temporal regions in the MF transsexuals. No significant correlations with time were seen in the FM transsexuals. In conclusion, although we did not find a specific pattern of cerebral activation in the FM transsexuals, we have identified a specific pattern of cerebral activation during a mental 3D rotation task in MF transsexuals under cross-sex hormonal treatment that differed from control males in the parietal region and from control females in the orbital prefrontal region. The hypoactivation in MF transsexuals in the parietal region could be due to the hormonal treatment or could reflect a priori cerebral differences between MF transsexual and control subjects.

Primary progressive aphasia (PPA) is a neurodegenerative syndrome characterized by insidious language deterioration. This young-onset disorder leaves adults with reduced communication skills for participation in social activities. There is limited evidence regarding group treatment for individuals with PPA, though the principles of chronic aphasia groups can be applied to this clinical population. We developed a PPA group treatment model incorporating compensatory strategies from augmentative and alternative communication (AAC), communication partner training from aphasia rehabilitation, and systematic instruction from dementia management. Six modules were designed and delivered to people with PPA and their communication partners in a university clinic setting over a 6-week period. Treatment was provided by graduate clinicians with supervision from a certified speech-language pathologist and faculty member. Primary treatment goals were to provide education about PPA symptoms and progression; to increase practice and use of multimodal communication by people with PPA; and to establish an environment where people with PPA and their partners could connect for training and support. We present pre/post comparisons and satisfaction data provided by five individuals with PPA and their partners in the group. Results suggest that group training is an effective service delivery model. Participants reported gains in both knowledge about PPA and in using many different modalities to communicate. The new compensatory strategies learned provide tools for maintenance and improvement of language use. Participants saw increased confidence and participation in daily activities, and highlighted the value of the PPA group for individuals with this relatively rare condition and their family members.

In order to establish the efficacy and biosimilar nature of AryoSeven to NovoSeven in the treatment of congenital factor VII (FVII) deficiency, patients received either agent at 30 μg/kg, intravenously per week for 4 weeks, in a randomized fashion. The primary aim was to compare FVII:coagulation activity (FVII:C), 20 minutes after recombinant activated FVII (rFVIIa) injection, in the 2 groups. A secondary measure was self-reported bleeding. The median interquartile baseline range of the plasma level of activated FVII (FVIIa) activity in the 2 groups was 1.6 (1.1-14.0) IU/dL and 5.0 (1.1-25.5) IU/dL. All patients achieved levels of FVIIa (FVII:C) >30 IU/dL, 20 minutes after the injection of rFVIIa. Bleeding was similar between the 2 groups, with a comparable decrease in severity and frequency compared to the last month prior to treatment. AryoSeven is similar to NovoSeven in increasing postinjection FVIIa activity as well as in clinical safety and efficacy. © The Author(s) 2014.

To determine the effect of <3 Mets (Metabolic Equivalent of Tasks) of physical activity on zero postoperative days for improving hemodynamic and respiratory parameters of patients after cardiac surgeries. Randomized control trial. BARMWTHospital, Rawalpindi, from March to August 2015. Arandomized controlled trial was conducted on 174 CABG and valvular heart disease patients undergoing cardiac surgical procedures. After selection of sample via non-probability purposive sampling, they were randomly allocated into interventional group (n=87) and control group (n=87). Treatment protocol for experimental group was ≤3 Mets of physical activity, i.e. chest physiotherapy, sitting over edge of bed, standing and sitting on chair at bedside, on zero postoperative day but the control group was treated with conventional treatment on first postoperative day. Pre- and post-treatment assessment was done in control and interventional groups on both zero and first postoperative days. Data was analyzed on SPSS version 21. The patients' mean age was 51.86 ±13.76 years. Male to female ratio was 132:42. Statistically significant differences in respiratory rate and SpO2 (p=0.000 and 0.000, respectively) were found between both groups. Among ABG's, PCO2 and pH showed significant differences with p values of 0.039 and <0.001, respectively. No significant differences were observed between both groups regarding electrolytes (Na+, K+, Cl-, p-values of 0.361, 0.575 and 0.120 respectively) and creatinine (p=0.783). Marked improvement in oxygen saturation, dyspnea and a fall in systolic BPwas seen in interventional group. There was also observed to be a reduction in the length of ICU stay among interventional group patients as frequency with percentage of total stay was compared to control group. Early physical activity (≤3 METS) post-cardiac surgeries prevent respiratory complications through improvement in dyspnea, respiratory rate, and oxygen saturation.

Intestinal lymphangiectasia (IL), a type of protein-losing enteropathy (PLE), is a dilatation of lymphatic vessels within the gastrointestinal tract. Dietary fat restriction previously has been proposed as an effective treatment for dogs with PLE, but limited objective clinical data are available on the efficacy of this treatment. To investigate the clinical efficacy of dietary fat restriction in dogs with IL that were unresponsive to prednisolone treatment or showed relapse of clinical signs and hypoalbuminemia when the prednisolone dosage was decreased. Twenty-four dogs with IL. Retrospective study. Body weight, clinical activity score, and hematologic and biochemical variables were compared before and 1 and 2 months after treatment. Furthermore, the data were compared between the group fed only an ultra low-fat (ULF) diet and the group fed ULF and a low-fat (LF) diet. Nineteen of 24 (79%) dogs responded satisfactorily to dietary fat restriction, and the prednisolone dosage could be decreased. Clinical activity score was significantly decreased after dietary treatment compared with before treatment. In addition, albumin (ALB), total protein (TP), and blood urea nitrogen (BUN) concentration were significantly increased after dietary fat restriction. At 2 months posttreatment, the ALB concentrations in the ULF group were significantly higher than that of the ULF + LF group. Dietary fat restriction appears to be an effective treatment in dogs with IL that are unresponsive to prednisolone treatment or that have recurrent clinical signs and hypoalbuminemia when the dosage of prednisolone is decreased. © 2014 The Authors.

Objective This study examined the individual and combined effects of two non-pharmacological treatments for Attention-Deficit/Hyperactivity Disorder (ADHD): Cogmed working memory training (CWMT) for adolescents, and behavioral parent training (BPT) for mothers. Method Ninety-one adolescents (ages 11–15) and their mothers were randomized to one of four CWMT and BPT treatment and active control (placebo) group combinations of 5-week interventions. At pre- and post-test, mothers and teachers completed rating forms, and adolescents completed neuropsychological measures of working memory (WM). Results Individual intervention effects showed that treatment CWMT significantly improved WM spans, whereas there were no significant differences for treatment or control BPT on reports of parenting-related outcomes. Combined treatment effects indicated an overall pattern of greatest improvements for the control CWMT/treatment BPT group, as compared to the other three groups, on adolescent WM deficit, behavioral regulation problems, and global executive deficit. Most significant effects for outcomes were main effects of improvements over time. Conclusions: Combination CWMT and BPT did not result in increased treatment gains. However, potential effects of combined treatment may have been masked by greater perceived benefits arising from lack of struggle in the non-adaptive, CWMT active control condition. Future combined intervention research should focus on specific, theoretically-driven WM deficits among individuals with ADHD, include possible adaptations to the standard CWMT program, examine effectiveness of cognitive treatments combined with contextual interventions, and utilize appropriate control groups to fully understand the unique and combined effects of interventions.

Oxidative stress plays a critical role in the development of hypercholesterolemia-induced complications. This study evaluated the effects of aspirin and Salix alba hydroethanolic extract on oxidative stress in the heart and kidney of hypercholesterolemic rabbits. The antioxidant activity, as well as total phenolic and salicin content of S. alba (Sa) extract were assessed by DPPH radical scavenging activity, Folin-Ciocalteu and HPLC methods, respectively. Animals were divided into two groups of control (fed with normal chow), and HD (fed with high cholesterol diet for 6 weeks). Then, hypercholesterolemic animals allocated to the following treatment groups: CHO (received HD), Sa extract (HD plus extract 60 and 120 mg/kg), and aspirin (HD plus aspirin 120 mg/kg) and received the treatments on a daily basis for 6 weeks. MDA, GSH, and nitrite concentrations as well as the activities of SOD and CAT were evaluated in cardiac and kidney tissues. The scavenging activity, total phenolic content and salicin were 19.1 µg/ml (IC50), 153.75 ± 3.6 mg of gallic acid/g, and 18.03 µg/mg, respectively. In comparison to CHO group, MDA levels were diminished in Sa and ASA groups but GSH levels were improved. NO metabolites increased in the heart of Sa 120 mg/kg group and in the kidney of all Sa and ASA treated groups. SOD activity increased only in the heart of Sa groups and in the kidney of Sa and ASA groups. CAT activity increased in the heart and kidney tissues of all Sa and ASA treated groups. The results showed S. alba extract improved redox homeostasis in heart and kidney tissues of hypercholesterolemic rabbits. The extract antioxidant property may be related to its phenolic content.

to study the efficacy of the GABA-ergic drug pantogam active (D-, L-gopantenic acid) in patients with schizophrenia treated with typical neuroleptics and to assess the rate of treatment response and tolerability of the drug. A sample consisted of 70 patients with schizophrenia stratified into main (n=35) and control (n=35) groups. All patients received one of typical antipsychotics (haloperidol, zuclopenthixol, promazine or perphenazine). Patients of the main group received in addition pantogam active in dose of 1200-1800 mg daily. The maximum allowed dose of 1800 mg daily was used in 62.9% of the patients. The long-term combined therapy with the addition of D-, L-gopantenic acid (pantogam activ) allowed to achieve clinical improvement earlier (on 8th week in the main group versus 16th week in the control group). The frequency and severity of secondary negative symptoms associated with antipsychotic therapy were decreased as well. The high efficacy and tolerability of the combined therapy allow to improve quality of life in patients with schizophrenia and their compliance to treatment as well as to reduce costs of medical care.

Nineteen obese individuals seeking treatment for binge eating disorder (BED) were compared with 19 non-BED obese individuals (OB) and 19 lean control subjects (LC) while performing a monetary reward/loss task that parses anticipatory and outcome components during functional magnetic resonance imaging. Differences in regional activation were investigated in BED, OB, and LC groups during reward/loss prospect, anticipation, and notification. Relative to the LC group, the OB group demonstrated increased ventral striatal and ventromedial prefrontal cortex activity during anticipatory phases. In contrast, the BED group relative to the OB group demonstrated diminished bilateral ventral striatal activity during anticipatory reward/loss processing. No differences were observed between the BED and LC groups in the ventral striatum. Heterogeneity exists among obese individuals with respect to the neural correlates of reward/loss processing. Neural differences in separable groups with obesity suggest that multiple, varying interventions might be important in optimizing prevention and treatment strategies for obesity.

Objectives: This study was planned to investigate the effects of pre and post-treatment of young inflorescence of Cocos nucifera (CnI) on alloxan-induced diabetic rats. Materials and Methods: Male albino Sprague Dawely rats were divided into five groups of six animals each. Group I was normal control, Group II was diabetic control, Cocos nucifera Inflorescence (CnI) was fed along with diet [20% (w/w)] orally (Group III) for a period of 11 days prior to alloxan injection (150 mg/kg i.p.). The curative effect of CnI was evaluated at the same feeding levels in alloxan-induced diabetic rats (Group IV) for a period of 30 days. The effects of both pretreatment and post-treatment (Group V) were also evaluated. Biochemical parameters such serum glucose, hepatic glycogen, and enzymes involving carbohydrate metabolism (hexokinase, phosphoglucomutase, pyruvate kinase, glucose-6-phosphatase, fructose 1, 6-diphosphatase, glucose-6 phosphate dehydrogenase, and glycogen phosphorylase) were assayed along with pancreatic histopathology. Data were analyzed using one-way analysis of variance followed by Duncan's post hoc multiple variance test. P < 0.05 was considered statistical significant. Results: Diabetic control rats showed significant increase in serum glucose (P < 0.05) and decrease in hepatic glycogen levels (P < 0.05) compared to normal rats, which was reversed to near normal in both CnI pretreated and post-treated rats. Treatment with CnI resulted in significant decrease (P < 0.05) in activities of gluconeogenic enzymes in Group III and IV on compared to the diabetic control group, while glycolytic enzyme activities were improved in these groups. The cytotoxicity of pancreatic islets also ameliorated by treatment with CnI on histopathological examination. Conclusion: The results obtained in the study indicate the protective and curative effects of CnI on alloxan-induced pancreatic cytotoxicity, which is mediated through the regulation of carbohydrate metabolic enzyme activities and islets cell repair.

Human populations are increasingly exposed to various carcinogens such as chemicals, radiation, and viruses in the environment. Chemopreventive drugs of plant origin are a promising strategy for cancer control because they are generally nontoxic or less toxic than synthetic che-mopreventive agents, and can be effective at different stages of carcinogenesis. The present investigation was undertaken to explore the antitumor activity of topical treatment with aloe vera (Aloe vera) gel, oral treatment with aloe vera extract, and topical and oral treatment with both gel and extract in stage-2 skin carcinogenesis in Swiss albino mice induced by 7,12-dim ethylbenz(a)anthracene (DMBA) and promoted croton (Croton tiglium) oil. The animals were randomly divided into 4 groups and treated as follows: Group I, DMBA + croton oil only (controls); Group II, DMBA + croton oil + topical aloe vera gel; Group III, DMBA + croton oil + oral aloe vera extract; Group I V, DMBA + croton oil + topical aloe vera gel + oral aloe vera extract. Results showed that body weight was significantly increased from 78.6% in the control group (Group I) to 92.5%, 87.5%, and 90.0% in Groups II, III, and I V, respectively. A 100% incidence of tumor development was noted in Group I, which was decreased to 50%, 60%, and 40% in Groups II, III, and I V, respectively. Also in Groups II, III, and IV, the cumulative number of papillomas was reduced significantly from 36 to 12, 15, and 11; tumor yield from 3.6 to 1.2, 1.5, and 1.1; and tumor burden from 3.6 to 2.4, 2.50, and 2.75, respectively, after treatment with aloe vera. Conversely, the average latent period increased significantly from 4.9 (Group I) to 5.23, 5.0, and 6.01 weeks in Groups II, III, and I V, respectively. We conclude that aloe vera protects mice against DMBA/croton oil-induced skin papillomagenesis, likely due to the chemopreventive activity of high concentrations of antioxidants such as vitamins A, C, and E; glutathione peroxidase; several isozymes of superoxide dismutase; the minerals selenium and zinc; and polysaccharides in aloe vera.

Effects of CPAP-therapy on brain electrical activity in obstructive sleep apneic patients: a combined EEG study using LORETA and Omega complexity : reversible alterations of brain activity in OSAS.

Effects of initiation of continuous positive airway pressure (CPAP) therapy on EEG background activity were investigated in patients with obstructive sleep apnea syndrome (OSAS, N = 25) to test possible reversibility of alterations of brain electrical activity caused by chronic hypoxia. Normal control group (N = 14) was also examined. Two EEG examinations were done in each groups: at night and in the next morning. Global and regional (left vs. right, anterior vs. posterior) measures of spatial complexity (Omega complexity) were used to characterize the degree of spatial synchrony of EEG. Low resolution electromagnetic tomography (LORETA) was used to localize generators of EEG activity in separate frequency bands. Before CPAP-treatment, a significantly lower Omega complexity was found globally and over the right hemisphere. Due to CPAP-treatment, these significant differences vanished. Significantly decreased Omega complexity was found in the anterior region after treatment. LORETA showed a decreased activity in all of the beta bands after therapy in the right hippocampus, premotor and temporo-parietal cortex, and bilaterally in the precuneus, paracentral and posterior cingulate cortex. No significant changes were seen in control group. Comparing controls and patients before sleep, an increased alpha2 band activity was seen bilaterally in the precuneus, paracentral and posterior cingulate cortex, while in the morning an increased beta3 band activity in the left precentral and bilateral premotor cortex and a decreased delta band activity in the right temporo-parietal cortex and insula were observed. These findings indicate that effect of sleep on EEG background activity is different in OSAS patients and normal controls. In OSAS patients, significant changes lead to a more normal EEG after a night under CPAP-treatment. Compensatory alterations of brain electrical activity in regions associated with influencing sympathetic outflow, visuospatial abilities, long-term memory and motor performances caused by chronic hypoxia could be reversed by CPAP-therapy.

This study was designed to investigate an alternative to the use of traditional physical laboratory activities in a communication systems course. Specifically, this study examined whether as an alternative, computer simulation is as effective as physical laboratory activities in teaching college-level electronics engineering education students about the concepts of signal transmission, modulation and demodulation. Eighty undergraduate engineering students participated in the study, which was conducted at a southeastern four-year university. The students were randomly assigned to two groups. The groups were compared on understanding the concepts, remembering the concepts, completion time of the lab experiments and perception toward the laboratory experiments. The physical group's (n = 40) treatment was to conduct laboratory experiments in a physical laboratory. The students in this group used equipment in a controlled electronics laboratory. The Simulation group's (n = 40) treatment was to conduct similar experiments in a PC laboratory. The students in this group used a simulation program in a controlled PC lab. At the completion of the treatment, scores on a validated conceptual test were collected once after the treatment and again three weeks after the treatment. Attitude surveys and qualitative study were administered at the completion of the treatment. The findings revealed significant differences, in favor of the simulation group, between the two groups on both the conceptual post-test and the follow-up test. The findings also revealed significant correlation between simulation groups' attitude toward the simulation program and their post-test scores. Moreover, there was a significant difference between the two groups on their attitude toward their laboratory experience in favor of the simulation group. In addition, there was significant difference between the two groups on their lab completion time in favor of the simulation group. At the same time, the qualitative research has uncovered several issues not explored by the quantitative research. It was concluded that incorporating the recommendations acquired from the qualitative research, especially elements of incorporating hardware experience to avoid lack of hands-on skills, into the laboratory pedagogy should help improve students' experience regardless of the environment in which the laboratory is conducted.

We formed a self-funded hypertension treatment group in a resource-poor community in rural Honduras. After training community health workers and creating protocols for standardized treatment, we used group membership fees to maintain the group, purchase generic medications in bulk on the local market, and hire a physician to manage treatment. We then assessed whether participation in the group improved treatment, medication adherence, and hypertension control. This is a program evaluation using quasi-experimental design and no control group. Using data from the 86 members of the hypertension treatment group, we analyzed baseline and follow-up surveys of members, along with 30 months of clinical records of treatment, medication adherence, and blood pressure readings. Our initial hypertension needs assessment revealed that at baseline, community hypertensives relied on the local Ministry of Health clinic as their source of anti-hypertensive medications and reported that irregular supply interfered with medication adherence. At baseline, hypertension group members were mainly female, overweight or obese, physically active, non-smoking, and non-drinking. After 30 months of managing the treatment group, we found a significant increase in medication adherence, from 54.8 to 76.2% (p<0.01), and hypertension control (<140/90 mmHg), from 31.4 to 54.7% (p<0.01). We also found a mean monthly decrease of 0.39 mmHg in systolic blood pressure (p<0.01). At the end of the 30-month observation period, the local Ministry of Health system had increased provision of low-cost anti-hypertensive medications and adopted the hypertension treatment group's treatment protocols. Formation of a self-funded, community-based hypertension treatment group in a rural, resource-poor community is feasible, and group participation may improve treatment, medication adherence, and hypertension control and can serve as a political driver for improving hypertension treatment services provided by the public system.

Effects of Nicotine Exposure on In Vitro Metabolism of Chlorpyrifos in Male Sprague-Dawley Rats

DOE Office of Scientific and Technical Information (OSTI.GOV)

Lee, Sookwang; Busby, Andrea L.; Timchalk, Charles

Chlorpyrifos (CPF) is a common organophosphate (OP) insecticide which is metabolized by CYP450s to the neurotoxic metabolite, chlorpyrifos-oxon (CPF-oxon) and a non-toxic metabolite, 3,5,6-trichloro-2-pyridinol (TCP). The objective of this study was to quantify the effect of repeated in vivo nicotine exposures on CPF in vitro metabolism and marker substrate activities in rats. Male Sprague-Dawley rats were dosed subcutaneously with 1 mg nicotine/kg/, for up to 10 days. Animals showed signs of cholinergic crisis after the initial nicotine doses, but exhibited adaptation after a couple days of treatment. Rats were sacrificed on selected days 4 or 24 hr after the lastmore » nicotine-treatment. While CYP450 reduced CO spectra were not different across the treatments, the single nicotine dose group showed a 2-fold increase in CYP2E1 marker substrate (p-nitrophenol) activity 24 hr after a single nicotine treatment compared to saline controls. Conversely, repeated nicotine treatments resulted in decreased EROD marker substrate activity 4 hr after the 7th day of treatment. CPF-oxon Vmax and Km did not show significant changes across the different nicotine treatment groups. The Vmax describing the metabolism of CPF to TCP was increased on all groups (days 1, 7, and 10) 24 hr after nicotine treatment but were unchanged 4 hr after nicotine treatment. Results of this in vitro study suggest that repeated nicotine exposure (i.e., from smoking) may result in altered metabolism of CPF. Future in vivo experiments based on these results will be conducted to ascertain the impact of in vivo nicotine exposures on CPF metabolism in rats.« less

Aronia melanocarpa has attracted scientific interest due to its dense contents of different polyphenols. We aimed to analyse effects of Aronia melanocarpa (AME) extract on blood pressure (BP), lipid peroxidation, cytokine level, total NOS activity in the left ventricle (LV), and aorta of L-NAME-induced hypertensive rats. 12-week-old male WKY rats were assigned to the control group and groups treated with AME extract (57.90 mg/kg/day), L-NAME (40 mg/kg/day), or combination of L-NAME (40 mg/kg/day) and AME (57.90 mg/kg/day) in tap water for 3 weeks. NOS activity, eNOS protein expression, and conjugated diene (CD) concentration were determined in the LV and aorta. After 3 weeks of L-NAME treatment, BP was increased by 28% and concomitant treatment with AME reduced it by 21%. NOS activity of the LV and aorta in the L-NAME group was decreased by about 40%, while AME increased it almost on the control level. AME-induced eNOS upregulation may contribute to increase NOS activity. Moreover, AME decreased CD concentration in the LV and aorta and TNF- α and IL-6 production in the plasma were increased by L-NAME treatment. In conclusion, our results showed that active substances of Aronia melanocarpa may have a positive effect on blood pressure, NOS activity, and proinflammatory processes in L-NAME-induced hypertension.

The aim of this study was to evaluate the effects of acute alcohol consumption and vitamin E co-treatment upon oxidative stress parameters in rats tongue. Thirty-eight, Wistar rats were separated into five groups (alcohol, alcohol/vitamin E, control, Tween, vitamin E). Alcohol and alcohol vitamin E groups had the standard diet, and 40% alcohol on drinking water. Other groups were fed with the same standard diet and water ad libitum. Vitamin E was given by gavage to vitamin E and alcohol/vitamin E rats twice a week. Alcohol and control groups were subjected to saline gavage and Tween group to 5% Tween 80 solution, the vitamin E vehicle. At day 14, the animals were anesthetized and specimens were obtained from tongue. Lipid peroxidation (TBARS), protein oxidative damage, catalase (CAT) and superoxide dismutase (SOD) activities were quantified. Alcohol group decreased TBARS in relation to control group and alcohol vitamin-treated animals decreased TBARS when compared to Tween and vitamin E groups. SOD activity was lower and CAT activity was higher in animals treated with both alcohol and vitamin E. These results suggest that short-term alcohol consumption decreases lipid peroxidation levels. Alternatively, alcohol/vitamin E group increased CAT, showing the toxicity of this association.

Twenty-nine polydrug abusers were randomly assigned to three out-patient treatment groups after inpatient detoxification. The groups were outpatient psychotherapy (1) with urine surveillance, (2) without surveillance, and (3) waiting list control. Tests were administered before and 3 months after outpatient treatment began. All groups made positive changes during treatment including significant reduction in drugs abused and numbers of subjects reporting less time spent in illegal activity. Notable significant differences were Group 3's reduction in social introversion vs Groups 1 and 2, and Group 1's retaining fewer drug-using friends and showing greatest reduction in barbiturate use frequency vs Groups 2 and 3. Experimenters concluded urine surveillance was somewhat helpful as an adjunct to outpatient psychotherapy but suggested its effect could be amplified by employing more rigorous surveillance procedures, especially if contingency contracting were utilized.

Oxidative stress plays important role in the pathogenesis of Alzheimer's disease (AD). Edaravone is a potent free radical scavenger that exerts antioxidant effects. Therefore, in this study we aimed to investigate neuroprotective effects of edaravone for AD. Wistar rats were randomly divided into three groups (n = 15): control group, model group, and treatment group, which were injected with phosphate buffered saline, Aβ1-40, and Aβ1-40 together with 5 mg/kg edaravone, respectively, into the right hippocampal dentate gyrus. Spatial learning and memory of the rats were examined by Morris water maze test. 4-Hydroxynonenal (4-HNE) level in rat hippocampus was analyzed by immunohistochemistry. Acetylcholinesterase (AChE) and choline acetylase (ChAT) activities were assayed by commercial kits. We found that edaravone ameliorated spatial learning and memory deficits in the rats. 4-HNE level in the hippocampus as well as AChE and ChAT activities in the hippocampus was significantly lower in treatment group than in model group. In conclusion, edaravone may be developed as a novel agent for the treatment of AD for improving cholinergic system and protecting neurons from oxidative toxicity.

Neutrophil elastase (NE) takes part in the pathogenesis of acute lung injury. However, its role in lung injury of burn-blast combined injury is unclear. Our objective was to assess the role of NE, and effect of sivelestat, a specific NE inhibitor, in lung injury induced by burn-blast combined injury in rats. One hundred and sixty male Sprague-Dawley rats were randomly subjected to burn-blast combined injury (BB) group, burn-blast combined injury plus sivelestat treatment (S) group or control (C) group. Blood gas, protein concentration and NE activity in bronchoalveolar lavage fluid (BALF), pulmonary myeloperoxidase (MPO) activity, serum concentrations of TNF-α and IL-8, etc. were investigated from 0 h to 7 d post-injury. In BB group, PaO2 decreased, while NE activity in BALF, total protein concentration in BALF, pulmonary MPO activity and W/D ratio, serum concentrations of TNF-α and IL-8 increased with neutrophil infiltration, progressive bleeding and pulmonary oedema. Compared with BB group, sivelestat treatment decreased the NE activity and ameliorated the above indexes. Sivelestat, exerts a protective effect in lung injury after burn-blast combined injury through inhibiting NE activity to decrease pulmonary vascular permeability, neutrophil sequestration, and production of TNF-α and IL-8.

The objective of this trial was to study the influence of dietary fiber sources on the gastrointestinal fermentation, digestive enzyme activity, and mucosa morphology of growing Greylag geese. In total, 240 Greylag geese (28-day-old) were allocated to 4 treatments (15 pens/treatment) differing in dietary fiber source: corn straw silage (CSS group), steam-exploded corn straw (SECS group), steam-exploded wheat straw (SEWS group), or steam-exploded rice straw (SERS group). At 112 days of age, 15 birds per group were euthanized to collect samples. No difference (P > 0.05) was found on all the gastrointestinal pH values and ammonia-nitrogen concentrations between the groups. The CSS and SERS groups had a lower (P < 0.05) proportion of acetic acid in the gizzard than the SECS and SEWS groups. The CSS group had a higher VFA concentration in the jejunum (P < 0.05) and acetic acid proportion (P < 0.01) in the ceca, and a lower (P < 0.01) butyric acid proportion than the other groups except for the SECS group. The SECS group had a higher (P < 0.01) acetic acid proportion and lower (P < 0.05) proportions of propionic acid and valeric acid in the ceca than the SEWS and SERS groups. Different fiber sources resulted in different VFA profiles, especially in the gizzard and ceca. Almost all gastrointestinal protease activities of the CSS group were higher (P < 0.05) than the other groups, along with lower (P < 0.01) amylase activities in the duodenum, jejunum, ileum, and ceca. Lipase activity in proventriculus was highest (P < 0.01) in the SEWS group and its cecal activity was lower (P < 0.01) in the SECS and SEWS groups than the CSS and SERS groups with a higher (P < 0.01) lipase activity in the CSS group than the SERS group. The SECS and SERS groups had a higher cellulase activity in the ceca than the CSS and SEWS groups, with a higher (P < 0.01) rectal cellulase activity in the SERS group than the other groups. There was no significant effect (P > 0.05) on the intestinal mucosa morphology. These results suggest that corn straw silage improves protein digestion while steam-exploded straw provides more energy. © 2015 Poultry Science Association Inc.

Following research indicating that the treatment needs of women are different from those of men, researchers and clinicians have argued that drug treatment programs for women should be designed to take their needs into account. Such programs tend to admit only women and incorporate philosophies and activities that are based on a social, peer-based model that is responsive to their needs. To assess the relative effectiveness of women-only (WO) outpatient programs compared to mixed-gender (MG) outpatient programs, 291 study volunteers were recruited (152 WO, 139 MG), and a 1-year follow-up was completed with 259 women (135 WO, 124 MG). Using bivariate, logistic regression, and generalized estimating equation analysis, the following four outcomes were examined: drug and alcohol use, criminal activity, arrests, and employment. In both groups, women showed improvement in the four outcome measures. Comparison of the groups on outcomes yielded mixed results; women who participated in WO treatment reported significantly less substance use and criminal activity than women in MG treatment, but there were no differences in arrest or employment status at follow up compared with those in MG treatment.

The aim of this study was to compare the immediate effects, on pressure pain sensitivity and active mouth opening, following the application of neuromuscular or strain/counter-strain technique in latent myofascial trigger points (MTrPs) in the masseter muscle. Seventy-one subjects, 34 men and 37 women, aged 20-65 years old, participated in this study. Subjects underwent a screening process to establish the presence of MTrPs in the masseter muscle. Subjects were divided randomly into three groups: group A which was treated with a neuromuscular intervention, group B treated with the strain/counter-strain technique, and group C as control group. Each treatment group received a weekly treatment session during 3 consecutive weeks. Outcomes measures were pressure pain thresholds (PPTs), active mouth opening and local pain (visual analogue scale, VAS) elicited by the application of 2.5kg/cm(2) of pressure over the MTrP. They were captured at baseline and 1 week after discharge by an assessor blinded to the treatment allocation of the subject. The ANOVA found a significant groupxtime interaction (F=25.3; p<0.001) for changes in PPT, changes in active mouth opening (F=10.5; p<0.001), and local pain evoked by 2.5kg/cm(2) of pressure (F=10.1; p<0.001). Within-group effect sizes were large (d>1) for PPT and mouth opening, and moderate for local pain (d<0.7, 0.5) in both intervention groups; but small (d<0.2) for the control group in all outcomes. No significant differences between both intervention groups were found for any outcome (p>0.8). Our results suggest that neuromuscular or strain/counter-strain technique might be employed in the management of latent MTrPs in the masseter muscle.

1. The present study was designed to investigate the effects of high-dose melatonin on lipid peroxidation and anti-oxidant enzyme activity in rats with experimentally induced hyperthyroidism. 2. Twenty-four albino male rats, weighing 240-260 g, were randomly allotted into one of three experimental groups (control, hyperthyroid and hyperthyroid + melatonin treatment), with each group containing eight animals. Hyperthyroidism was induced by a daily with i.p. injection of 200 microg l-thyroxine for 30 days. In addition to l-thyroxin treatment, rats in the hyperthyroid + melatonin treatment group were also given daily i.p. injections of 10 mg/kg melatonin on the last 10 days of l-thyroxine treatment. Control animals received injections of an equivalent volume of saline solution. Rats received the last injection 24 h before being killed. 3. At the end of the experiment, rats in all three groups were fasted for 12 h and killed by cardiac puncture under ether anaesthesia. Blood samples were taken for the determination of malondialdehyde (MDA), glutathione (GSH) and superoxide dismutase (SOD) levels and concentrations of tri-iodothyronine (T(3)) and thyroxine (T(4)). 4. It was found that MDA and SOD levels and concentrations of T(3) and T(4) were higher and the GSH level was lower in rats with hyperthyroidism compared with controls. Melatonin treatment decreased the elevated MDA and SOD levels and increased the lowered GSH level to control levels in rats with hyperthyroidism, but did not ameliorate the concentrations of T(3) and T(4). 5. It was concluded that high-dose melatonin treatment may decrease the hyperthyroidism-induced disturbances of lipid peroxidation and anti-oxidant enzyme activity and oxidative damage.

Objective To determine whether environmental control using nocturnal temperature controlled laminar airflow (TLA) treatment could improve the quality of life of patients with persistent atopic asthma. Design Randomised, double-blind, placebo-controlled, parallel-group trial. Setting Nineteen European asthma clinics. Participants 312 patients aged 7–70 with inadequately controlled persistent atopic asthma. Main outcome measure Proportion of patients with an increase of ≥0.5 points in asthma quality of life score after 1 year of treatment. Results TLA devices were successfully installed in the bedrooms of 282 (90%) patients included in the primary efficacy analysis. There was a difference in treatment response rate between active (143 of 189, 76%) and placebo (56 of 92, 61%) groups, difference 14.8% (95% CI 3.1 to 26.5, p=0.02).3 In patients aged ≥12, on whom the study was powered, the difference in response rate was similar-active 106 of 143 (74%), placebo 42 of 70 (60%), difference 14.1% (0.6 to 27.7, p=0.059). There was a difference between groups in fractional exhaled nitric oxide change of −7.1 ppb (−13.6 to −0.7, p=0.03). Active treatment was associated with less increase in cat-specific IgE than placebo. There was no difference in adverse event rates between treatment groups. Conclusion Inhalant exposure reduction with TLA improves quality of life, airway inflammation and systemic allergy in patients with persistent atopic asthma. TLA may be a treatment option for patients with inadequately controlled persistent atopic asthma. Trial registration number Clinical Trials NCT00986323. PMID:22131290

Orthodontic treatment is one of the commonly used dental treatments. Orthodontic forces act on the bone by modulating the biomolecules, chiefly the osteoprotegerin (OPG), osteopontin (OPN), receptor activator of nuclear factor kappa-B (RANK), and RANK ligand (RANKL) (OPG ligand). Hormonal changes are known to cause marked alteration in the levels of these biomolecules. Hence, we planned this study to evaluate the response of bone biomarkers in the gingival crevicular fluid (GCF) in postmenopausal women undergoing fixed orthodontic therapy. This study included assessment of 50 subjects who underwent orthodontic treatment from June 2012 to July 2016. All the patients were divided into two study groups with 25 patients in each group: premenopausal group and postmenopausal group. Similar orthodontic wires were used for controlling the forces applied in subjects of both the study groups and their GCF levels of RANKL, and OPN was assessed at baseline and 24 hours after the activation of orthodontic forces. All the results were compiled, assessed, and analyzed by Statistical Package for the Social Sciences software version 16.0. Chi-square test, Student's t-test, and Mann-Whitney U test were used for the assessment of the level of significance. The mean values of RANKL and OPN in the premenopausal and postmenopausal groups were found to be 241.52 and 317.15 pg/μL respectively. The mean values of RANKL at baseline in the premenopausal and postmenopausal groups were found to be 7.15 and 3.84 pg/μL respectively. Nonsignificant results were obtained while comparing mean OPN and RANKL level alteration in between the two study groups. The mean alterations in the GCF levels of bone biomarkers are similar for both premenopausal and postmeno-pausal women. For women with either premenopausal or postmenopausal status, orthodontic treatment appears to be equally safer.

To measure the effects of nonhypercalcemic vitamin D receptor agonist elocalcitol on bladder function in rats with cyclophosphamide-induced cystitis and on bladder function and sensory nerve activity in a mouse with acetic acid-evoked bladder irritation. Female Wistar rats and male Balb/C mice were gavaged once daily with elocalcitol diluted in miglyol 812 (treatment group) or miglyol alone (control group). On experimental day 12, polyethylene tubing was implanted into the urinary bladder in all the animals. In the mice, a bipolar electrode was positioned under a single postganglionic bladder nerve. At 48 hours after surgery, bladder function was measured in awake, freely moving rats during bladder filling with 0.9% NaCl and both bladder function and sensory nerve activity was measured in awake, restrained mice during continuous intravesical infusion of 0.9% NaCl followed by 0.25% acetic acid. In rats, the treatment group showed a significant increase in bladder capacity and decrease in number of nonvoiding bladder contractions. In mice, the filling pressure during saline infusion was similar in both groups; however, during acetic acid infusion, the average filling pressure was significantly increased (47%) in the control group but not in the elocalcitol treatment group. The firing rate at filling pressure for the treatment group was 3.6-fold and 2.7-fold lower than that in the control group during the saline and acetic acid infusion, respectively. Oral treatment with elocalcitol suppressed signs of detrusor overactivity in both animal models and exerted strong suppressive effect on urinary bladder sensory signaling during filling in mice.

Haloperidol can induce catalepsy and this drug effect can be conditioned as well as sensitized to contextual cues. We used a paired/unpaired Pavlovian conditioning protocol to establish haloperidol catalepsy conditioned and sensitized responses. Groups of rats were given 10 daily catalepsy tests following administration of vehicle (n=24) or haloperidol (1.0mg/kg) either paired (n=18) or unpaired (n=18) to testing. Subsequently, testing for conditioning was conducted and conditioning and sensitization of catalepsy were observed selectively in the paired group. Immediately following a second test for catalepsy conditioning, the groups were subdivided into 4 vehicle groups, 3 unpaired haloperidol groups and 3 paired haloperidol groups and were given one of three post-trial treatments (vehicle, 0.05mg/kg or 2.0mg/kg apomorphine). One day later the conditioned catalepsy test 3 was carried out and on the next day, a haloperidol challenge test was performed. The post-trial apomorphine treatments had major effects on the paired groups upon both conditioning and the haloperidol challenge test. The low dose apomorphine post-trial treatment enhanced both the conditioned and the haloperidol sensitized catalepsy responses. The high dose apomorphine post-trial treatment eliminated conditioned catalepsy and eliminated the initial acute catalepsy response to haloperidol that was induced in the vehicle control groups. These results demonstrate the sensitivity of conditioned drug cues to modification by increases/decreases in activity of the dopamine system in the immediate post-trial interval after a conditioning trial. This demonstration that post-trial dopaminergic drug treatments can modify conditioned drug behavior has broad implications for conditioned drug effects. Copyright © 2016 Elsevier B.V.

Plantar fasciitis (PF) is a soft tissue disorder considered to be one of the most common causes of inferior heel pain. The aim of this study was to investigate the effect of monophasic pulsed current (MPC) and MPC coupled with plantar fascia-specific stretching exercises (SE) on the treatment of PF. Forty-four participants (22 women and 22 men, with a mean age of 49 years) diagnosed with PF were randomly assigned to receive MPC (n=22) or MPC coupled with plantar fascia-specific SE (n=22). Prior to and after 4 weeks of treatment, participants underwent baseline evaluation; heel pain was evaluated using a visual analogue scale (VAS), heel tenderness threshold was quantified using a handheld pressure algometer (PA), and functional activities level was assessed using the Activities of Daily Living subscale of the Foot and Ankle Ability Measure (ADL/FAAM). Heel pain scores showed a significant reduction in both groups compared to baseline VAS scores (P<0.001). Heel tenderness improved significantly in both groups compared with baseline PA scores (P<0.001). Functional activity level improved significantly in both groups compared with baseline (ADL/FAAM) scores (P<0.001). However, no significant differences existed between the 2 treatment groups in all post-intervention outcome measures. This trial showed that MPC is useful in treating inferior heel symptoms caused by PF.

Background The positive effects of the Dutch Community Occupational Therapy in Dementia programme on patients' daily functioning were not found in a multicentre randomised controlled trial (RCT) in Germany. Objectives To evaluate possible effect modification on the primary outcome within the German RCT with regard to (1) participant characteristics, (2) treatment performance and (3) healthcare service utilisation; and (4) to compare the design and primary outcome between the German and the original Dutch study. Methods (1) The impact of participant baseline data on the primary outcome was analysed in exploratory ANCOVA and regression analyses. (2) Therapists completed questionnaires on context and performance problems. The main problems were identified by a qualitative content analysis and focus-group discussion. Associations of the primary outcome with scores of participant adherence and treatment performance were evaluated by regression analysis. (3) Utilisation rates of healthcare services were controlled for significant group differences. (4) Differences in the Dutch and German study design were identified, and the primary outcome was contrasted at the item level. Results (1) Participant characteristics could not explain more than 5% of outcome variance. (2) The treatment performance of some active intervention components was poor but not significantly associated with the primary outcome. (3) There were no significant group differences in the utilisation of healthcare resources. (4) In contrast to the Dutch waiting-control group, the active intervention in the German control group may have reduced group differences in the current RCT. The German patients demonstrated a higher independence at baseline and less improvement in instrumental activities of daily living. Conclusion The differences in outcome may be explained by a more active control treatment, partially poor experimental treatment and less room for improvement in the German sample. Future cross-national transfers should be prepared by pilot studies assessing the applicability of the intervention and patient needs specific to the target country.

This functional magnetic resonance imaging (fMRI) study investigated the effects of pharmacotherapy on brain function underlying affect dysregulation and cognitive function in pediatric bipolar disorder (PBD). Healthy controls (HC) (n=14; mean age =14.1 ± 2.4 years) and unmedicated PBD patients with manic or hypomanic episodes (n=17; mean age =14.3 ± 1.1 years) were matched on intelligence quotient (IQ) and demographic factors. The fMRI studies were performed at baseline and after 14 weeks, during which PBD patients were treated initially with second-generation antipsychotics (SGAs) followed by lamotrigine monotherapy. The pediatric affective color-matching task was used where subjects matched the color of a positive, negative, or neutral word with one of the two colored circles below in each of the trials. There were five blocks of each emotional word type, with 10 trials per block. Behavioral data showed that the PBD group was modestly slower and less accurate than the HC, regardless of condition or treatment status. The blood oxygen level-dependent (BOLD) signal activity was reduced with treatment in the PBD group relative to the HC group during the negative versus neutral condition in bilateral dorsolateral prefrontal cortex (DLPFC), right posterior cingulate gyrus, parahippocampal gyrus, and inferior parietal lobule, but increased in left ventromedial prefrontal cortex (VMPFC). Similarly, during the positive versus neutral condition, the PBD group, relative to HC, showed reduced activity in right DLPFC, precuneus, and inferior parietal lobule and increased activity in the right VMPFC. However, within the PBD group, there was treatment related decrease in VMPFC and DLPFC. Improvement on Young Mania Rating Scale (YMRS) score significantly correlated with the decreased activity in VMPFC within the patient group. Pharmacotherapy in PBD patients led to differential effort with persistently increased activity in the affective regions and decreased activity in the cognitive regions relative to HC, demonstrating altered mechanisms of affective and cognitive systems of brain function, regardless of symptom response.

A field trial was carried out during a summer-fall period on a commercial beef cattle farm in Minas Gerais State, located in the Southeast of Brazil. In order to evaluate the prophylactic effect and the curative efficacy of fipronil in a 1% solution, 200 Zebu crossbred bulls, with ages varying from 20 to 30 months and weights from 233 to 362 kg, were selected. The bulls were assigned by ranked pair to an untreated control group (A) or to a treated group (B), resulting in 100 animals per group. All experimental animals were surgically castrated on day 0, following routine procedures. After castration all animals in the group B were treated with 10 mg/kg bw of a 1% fipronil solution, topically on the dorsal mid-line. The wounds were individually inspected on days: 2, 4, 7, 10, 14, 17, 21, 28 and 35. After castration the animals were naturally exposed to Cochliomyia hominivorax and remained in the same pasture throughout the trial. Among the animals in the control group, 83 were observed to harbor C. hominivorax eggs, with a total of 97 ovipositions, and among those 73 animals had active myiasis. In group B (fipronil 1%), 66 animals showed C. hominivorax eggs, with 92 ovipositions and five animals with active myiasis. Most ovipositions and active myiasis were detected until seven days post-castration for both groups. Wound parasite infestation evidenced bleeding, serous purulent exudation and presence of active C. hominivorax larvae. Treatment with fipronil 1% had a prophylactic effect on scrotal wounds against the development of C. hominivorax larvae in more than 95% of the treated animals for up to 17 days after castration. The treatment showed partial protection of 66% and 50% on days 21 and 28 post-treatment (pt), respectively. Three animals from the control group and one from the treated group showed active screwworms on day 21 pt, and one animal from the treated group and two from the control group also presented C. hominivorax larvae on scrotal wounds on day 28 pt. By the end of the observation period (day 35 pt), the castration wound had healed in all animals. All experimental animals presenting scrotal wounds infested with C. hominivorax larvae were treated with a 1% pour-on formulation of fipronil, on the same day that infestation was observed. Active C. hominivorax larvae were not seen during the monitoring period immediately after treatment. The curative efficacy of fipronil 1% against C. hominivorax larvae infestation in castration wounds was 100%.

Many studies have shown that LPS mainly activates four signal transduction pathways to induce inflammation, namely the p38, ERK1/2, JNK and IKK/NF-κB pathways. Studies have demonstrated that 5'-AMP-induced hypothermia (AIH) exhibits high anti-inflammatory capabilities. In this study, we explore that how AIH inhibits the inflammatory response. Wistar rats were divided into five groups: a control group, an LPS group, a 5'-AMP pre-treatment group, a 5'-AMP post-treatment group and a 5'-AMP group. For each group, plasma and lung were collected from the rats at 6h and 12h after LPS injection. ELISA assays were used to detect plasma levels of CD14, CRP and MCP-1. Inflammatory pathway activation and TLR4 expression were assayed separately by Western blot analysis and immunohistochemistry. Our results showed that rats treated with AIH either before or after an LPS-challenge had a significant decrease in plasma levels of CD14, CRP and TLR4 compared with rats that received LPS only. Western blot analysis showed that AIH inhibited the activation of extracellular signal-regulated kinases (ERK) 1/2, p38, c-Jun N-terminal kinase (JNK) and NF-κB in inflammatory rats. Our study concluded that AIH attenuated LPS-induced inflammation mainly by inhibiting activation on the ERK1/2, p38, JNK and NF-κB signaling pathways. Copyright © 2014 Elsevier B.V.

Oxytetracycline wastewater is a major category of pharmaceutical wastewater, and its toxic effects on aquatic organisms have aroused people’s attention. In this study, Zebrafish were separately exposed to four Oxytetracycline wastewater treatments (20%, 40%, 60%, 80%) and a control group were sampled on days 3, 6, 9, 12, and 15. Superoxide dismutase (SOD) activities showed significant inhibition, but the highest SOD activity was found in 20% and 40% the treatment groups (195.12U/mgprot, 187.43U/mgprot, respectively) on the 12th day. MDA contents increased significantly compared with control group. MDA contents showed that the higher the volume concentration, the higher the contents of MDA with the increase of exposure time. The highest MDA content shown in 60% exposure group (5.49nmol/mgprot) on the 12th day. And SOD activities and MDA contents showed a trend of “Λ” type. In conclusion, Oxytetracycline wastewater induced oxidative stress and toxicity in Zebrafish muscle tissue.

The prevalence of rhinosinusitis is quite high. Despite the widespread use of antibiotics for rhinosinusitis, there are other forms of treatment, including phytotherapy. One of the most widely used herbal medicines for treatment of rhinosinusitis is Luffa operculata. This study aimed to evaluate the efficacy of topical nasal solution of the aqueous extract of L. operculata, determining the toxicity to its use and identifying the active principles presented in the aqueous extract. The secondary objective was to evaluate the action of active principles on bacteria commonly involved in acute rhino sinusitis. The study was conducted in experimental model of sinusitis. Three different concentrations of L. operculata were used as local treatment of rhino sinusitis. The results were compared with those observed in control groups that received nasal saline solution. Histological examination of the liver, kidney, spleen, myocardium, brain and lungs of all animals evaluated the toxicity of L. operculata. The aqueous extract used was subjected to chromatographic analysis and an active principle was isolated and tested for in vitro inhibition of bacterial colonies usually found in rhino sinusitis. Intranasal treatment of sinusitis with L. operculata showed better clinical evolution than control group. Statistically significant difference (p>0.10) between the treated group and the control group was observed in the histologic evaluation for inflammatory pattern. The aqueous extract of L. operculata used presented a predominance of 2,3-dicafeoilglicaric acid, a substance not yet described in the literature. There was a significant difference in bacterial growth of Streptococcus pyogenes on blood-agar plates when under the influence of both the aqueous extract and the active substance. Topical nasal solution of the aqueous extract of L. operculata is effective compared to the application of saline solution for the treatment of bacterial rhinosinusitis in an experimental model. L. operculata determined in vitro inhibition of growth of S. pyogenes. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial. Published by Elsevier Editora Ltda.

Chemoradiotherapy with temozolomide is the current standard treatment option for patients with glioblastoma. However, the majority of patients with glioblastoma survive for <2 years. Therefore, it is necessary to develop more effective therapeutic strategies for the treatment of glioblastoma. 7-O-succinyl macrolactin A tromethamine salt (SMA salt), a macrolactin compound, is known to possess an antiangiogenic activity. The present study investigated the antitumor effects of SMA salt in the treatment of glioblastoma by evaluating in vitro and in vivo antitumor effects of SMA salt in an experimental glioblastoma model. The antitumor effects of the drug on human glioblastoma U87MG, U251MG and LN229 cell lines were assessed using in vitro cell viability, migration and invasion assays. Nude mice with established U87MG glioblastoma were assigned to either the control or SMA salt treatment group. The volume of tumors and the duration of survival were also measured. SMA salt affected cell viability and caused a concentration-dependent inhibition effect on the migration and invasion of glioblastoma cell lines. Animals in the SMA salt treatment group demonstrated a significant reduction in tumor volume and an increase in survival (P<0.05). Treatment with SMA salt presented more cytotoxic effects as well as anti-migration and anti-invasion activity compared with the control group in vitro and in vivo . These results suggest that SMA salt has significant antitumor effects on glioblastoma.

The impact on tilapia fish of combined treatment of landfill leachate and domestic sewage was monitored in a waste treatment plant that operated on a pilot scale using the activated sludge process. Biomarkers of sub-lethal toxicity were used to indicate the possibility of damage to organisms due to interaction with pollutants. The concentration of metallothioneins did not indicate the increased presence of metals in fish exposed than in control groups. Acetylcholinesterase enzyme activity was inhibited in only one of the exposed groups, indicating the possible presence of organophosphate and/or carbamate pesticides in treated effluent. The PAHs used as biomarkers (naphthalene, pyrene, benzo(a)pyrene and 1-hydroxypyrene) indicated that exposed fish had a greater absorption of PAHs than control groups of fish, indicating the likely presence of these compounds in at least one of the combined treatment effluents. The frequencies of micronuclei and other erythrocytic nuclear abnormalities also indicate greater genotoxic damage in cells of organisms exposed than in control groups. The use of biomarkers proved to be important to permit an evaluation of sub-lethal damage present in organisms exposed to the pollution source studied.

Alteration in genetic expression is as important as gene mutation in cancer development and proliferation. Epigenetic changes affect gene expression without altering the DNA sequence. Histone deacetylase (HDAC), an enzyme facilitating histone remodelling, can lead to silencing of tumor suppressor genes making HDAC inhibitors viable anticancer drugs against tumors with increased activity of the enzyme. In this study we evaluated 18F-fluroacetamido-1-hexanoicanilide (18F-FAHA), an artificial HDAC substrate, as imaging probe of HDAC activity of human tumor xenografts in immunocompromised host mice. Human breast and melanoma cell lines, MDA-MB-468 and MDA-MB-435 respectively, known to overexpress HDAC activity were xenografted into immunocompromised mice and HDAC activity was imaged using 18F-FAHA. The melanoma group was treated with saline, SAHA (suberoylanilide hydroxamic acid, an approved anticancer HDAC inhibitor) in DMSO, or DMSO as positive control. Tracer kinetic modelling and SUV were used to estimate HDAC activity from dynamic PET data. Both breast tumor and melanoma group showed great variability in binding rate constant (BRC) of 18F-FAHA suggesting highly variable inter- and intra-tumoral HDAC activity. For the SAHA treated melanoma group, HDAC activity, as monitored by BRC of 18F-FAHA, decreased more than the two (positive and negative) control groups but not tumor growth. Our preliminary study showed that noninvasive PET imaging with 18F-FAHA has the potential to identify patients for whom treatment with HDAC inhibitors are appropriate, to assess the effectiveness of that treatment as an early marker of target reduction, and also eliminate the need for invasive tissue biopsy to individualize treatment.

Forty patients with classical or definite rheumatoid arthritis in a stage of active disease were treated for two weeks at a spa hotel. The patients were divided into four groups of 10. Group I was treated with daily mud packs, group II with daily hot sulphur baths, group III with a combination of mud packs and hot sulphur baths, and group IV served as a control group. The patients were assessed by a rheumatologist who was blinded to the treatment modalities. Statistically significant improvement for a period of up to three months was observed in the three treatment groups in most of the clinical indices. Improvement in the control group was minor in comparison and not statistically significant. No significant improvement was observed in any of the laboratory variables measured. Except for three mild cases of thermal reaction there were no side effects. PMID:2180388

The objective of the study was to perform a clinical, comparative assessment of the degree of postural deformities before and after the treatment of idiopathic scoliosis in patients treated with SpineCor brace compared to the control group. A group of 90 children with idiopathic scoliosis (including 74 girls) at the average age of 12.2 was subject to prospective observation. Average pre-treatment Cobb angle was 24.9° in the thoracic spine and 25.8° in the lumbar spine. The group actively treated with the SpineCor brace consisted of 45 children, while the control group consisted of the remaining 45 children with the natural course of the disease. Both groups did not differ significantly in terms of age, gender, height, body weight, Risser sign of skeletal maturity and baseline clinical and radiological parameters of scoliosis. Significant reduction of rib hump was observed upon 2-year SpineCor brace treatment (P=0.04) compared to the group treated by physiotherapy only (P=0.91). Similarly, improvement in lumbar prominence was observed in the actively treated group (P=0.009), with a trend towards worse results in the control group (P=0.07) In the group treated with the SpineCor brace, significant reduction in pectoral and hamstring muscle contractures as well as reduction in shoulder asymmetry and reduction in anterior and posterior vertical deviation were observed. Treatment using the SpineCor dynamic brace leads to a clinical improvement in posture, particularly to reduction in rib hump, lumbar prominence and muscular contractures.

To study effects of overexposure to androgens and subsequent antiandrogenic treatment on brain activity during working memory processes in women with polycystic ovary syndrome (PCOS). In this longitudinal study, working memory function was evaluated with the use of functional magnetic resonance imaging (MRI) in women with PCOS before and after antiandrogenic treatment. Department of reproductive medicine, university medical center. Fourteen women with PCOS and with hyperandrogenism and 20 healthy control women without any features of PCOS or other hormonal disorders. Antiandrogenic hormone treatment. Functional MRI response during a working memory task. At baseline women with PCOS showed more activation than the control group within the right superior parietal lobe and the inferior parietal lobe during task (all memory conditions). Task performance (speed and accuracy) did not differ between the groups. After antiandrogenic treatment the difference in overall brain activity between the groups disappeared and accuracy in the high memory load condition of the working memory task increased in women with PCOS. Women with PCOS may need additional neural resources during a working memory task compared with women without PCOS, suggesting less efficient executive functioning. This inefficiency may have effects on daily life functioning of women with PCOS. Antiandrogenic treatment appears to have a beneficial effect on this area of cognitive functioning. NTR2493.

To compare the efficacy in reducing neck pain and disability in an individualised physiotherapy treatment with group treatment in acute and subacute mechanical neck pain. Randomised clinical trial. Health Area of University Hospital Virgen del Rocío, Seville, Spain. A total of 90 patients diagnosed with mechanical neck pain of up to one month onset, distributed randomly into two groups: (i)individualised treatment; (ii)group treatment. The treatment consisted of 15 sessions of about 60minutes for both groups. Individual treatment consisted of 15minutes of infrared heat therapy, 17minutes of massage, and analytical passive stretching of the trapezius muscles and angle of the scapula. The group treatment consisted of a program of active mobilisation, isometric contractions, self-stretching, and postural recommendations. Pain was measured at the beginning and end of treatment pain using a Visual Analogue Scale (VAS) and an algometer applied on the trapezius muscles and angle of the scapula, and neck disability using the Neck Disability Index. Both treatments were statistically significant (P<.001) in improving all variables. Statistically significant differences (P<.001) were found for all of them in favour of individualised treatment compared to group treatment. Patients with acute or subacute mechanical neck pain experienced an improvement in pain and neck disability after receiving either of the physiotherapy treatments used in our study, with the individual treatment being more effective than collective.

Opuntia ficus-indica (L.) Mill. (Castaceae) (cactus) is used in Tunisian medicine for the treatment of various diseases. This study determines phytochemical composition of cactus cladode extract (CCE). It also investigates antioxidant activity and hepatoprotective potential of CCE against lithium carbonate (Li 2 CO 3 )-induced liver injury in rats. Twenty-four Wistar male rats were divided into four groups of six each: a control group given distilled water (0.5 mL/100 g b.w.; i.p.), a group injected with Li 2 CO 3 (25 mg/kg b.w.; i.p.; corresponding to 30% of the LD 50 ) twice daily for 30 days, a group receiving only CCE at 100 mg/kg of b.w. for 60 days and then injected with distilled water during the last 30 days of CCE treatment, and a group receiving CCE and then injected with Li 2 CO 3 during the last 30 days of CCE treatment. The bioactive components containing the CCE were identified using chemical assays. Treatment with Li 2 CO 3 caused a significant change of some haematological parameters including red blood cells (RBC), white blood cells (WBC), haemoglobin content (Hb), haematocrit (Ht) and mean corpuscular volume (VCM) compared to the control group. Moreover, significant increases in the levels of glucose, cholesterol, triglycerides and of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) activities were observed in the blood of Li 2 CO 3 -treated rats. Furthermore, exposure to Li 2 CO 3 significantly increased the LPO level and decreased superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities in the hepatic tissues. CCE possesses a significant hepatoprotective effect.

Nicotiana plumbignifolia (Linn) is used as folk medicine in the treatment of liver dysfunction in Pakistan. The present study was designed to investigate the hepatoprotective role of N. plumbignifolia methanolice extract (NPME) against carbon tetrachloride (CCl4)-induced oxidative damage in liver of chicks. Methanolic extract of N. plumbignifolia was obtained and was further evaluated as a hepatoprotective agent against CCl4-induced oxidative damage in liver of chicks. For this study, 60-day-old 50 male chicks were divided into five groups. Chicks of group 1 (control) had free access to food and water. Group II received 1 mL/kg of CCl4 (30% in olive oil v/v) via the intraperitoneal route thrice a week for 4 weeks. Group III received 100 mg/kg body weight (b.w.) of silymarin via gavage after 48 h of CCl4 treatment, whereas group IV were given 200 mg/kg b.w. NPME after 48 h of CCl4 treatment. Hepatoprotective activity was assessed by measuring the activities of the antioxidant enzymes: catalase, peroxidase, superoxide dismutase, glutathione peroxidase, glutathione reductase, and lipid peroxidation (thiobarbituric acid reactive substances (TBARS)). Serum was analyzed for various biochemical parameters. The results revealed that CCl4 induced oxidative stress as evidenced by the significant decrease in the activity levels of antioxidant enzymes, while an increase in the levels of TBARS in liver samples is compared with the control group. Serum levels lactate dehydrogenase, triglycerides, total cholesterol, and low-density lipoprotein was elevated while reducing high-density lipoprotein compared to controls. Cotreatment of NPME treatment reversed these alterations, which seems likely that NPME can protect the liver tissues against CCl4-mediated oxidative damage. © The Author(s) 2013.

We sought to better understand how dose and titration with duloxetine treatment may impact tolerability and treatment discontinuation in patients with major depressive disorder. We investigated Phase III duloxetine trials. Group 1 was a single placebo-controlled study with a 20 mg initial dose and a slow titration to 40 and 60 mg. Group 2 was a single study with a 40 mg initial dose and final "active" doses of 40 and 60 mg (5 mg control group), with 1-week titration. Group 3 consisted of eight placebo-controlled studies with starting doses of 40, 60, and 80 mg/day with minimal titration (final dose 40-120 mg/day). Tolerability was measured by rate of discontinuation due to adverse events (DCAE). The DCAE in Group 1 were 3.6% in the 60 mg group, 3.3% in the 40 mg group, and 3.2% in the placebo group. In Group 2, the DCAE were 15.0% in the 60 mg group, 8.1% in the 40 mg group, and 4.9% in the 5 mg group. In Group 3, the DCAE were 9.7% and 4.2% in the duloxetine and placebo groups, respectively. This study suggests that starting dose and titration may have impacted tolerability and treatment discontinuation. A lower starting dose of duloxetine and slower titration may contribute to improving treatment tolerability for patients with major depressive disorder.

Combination therapy with methotrexate (MTX) and tumour necrosis factor (TNF) blockade has increased remission rates in patients with rheumatoid arthritis. However, there are no guidelines regarding cessation of therapy. There is a need for markers predictive of sustained remission following cessation of TNF blocker therapy. Patients in remission (DAS28 <2.6) treated with a TNF blocker and MTX as initial or delayed therapy were recruited. Joints were assessed for grey scale synovitis and power Doppler (PD) activity. Immunological assessment involved advanced six-colour flow cytometry. Of the 47 patients recruited, 27 had received initial treatment and 20 delayed treatment with TNF blocking drugs. Two years after stopping TNF blocker therapy, the main predictor of successful cessation was timing of treatment; 59% of patients in the initial treatment group sustained remission compared with 15% in the delayed treatment group (p=0.003). Within the initial treatment group, secondary analysis showed that the only clinical predictor of successful cessation of treatment was shorter symptom duration before receiving treatment (median 5.5 months vs 9 months; p=0.008). No other clinical features were associated with successful cessation of therapy. Thirty-five per cent of patients had low PD activity but levels were not informative. Several immunological parameters were significantly associated with sustained remission including abnormal differentiation subset of T cells and regulatory T cells. Similar non-significant trends were observed in the delayed treatment group. In patients in remission with low levels of imaging synovitis receiving combination treatment with a TNF blocker and MTX, immunological parameters and short duration of untreated symptoms were associated with successful cessation of TNF blocker therapy.

Treatment of human pulmonary artery smooth muscle cells with ET-1 stimulated PLD and NADPH oxidase activities, which were inhibited upon pretreatment with bosentan (ET-1 receptor antagonist), FIPI (PLD inhibitor), apocynin (NADPH oxidase inhibitor) and EGCG & ECG (catechins having galloyl group), but not EGC & EC (catechins devoid of galloyl group). Herein, we determined the probable mechanism by which the galloyl group containing catechins inhibit ET-1 induced stimulation of PLD activity by molecular docking analyses based on our biochemical studies. ET-1 induced stimulation of PLD activity was inhibited by SecinH3 (inhibitor of cytohesin). Arf-6 and cytohesin-1 were associated in the cell membrane, which was not inhibited by the catechins during ET-1 treatment to the cells. However, EGCG and ECG inhibited binding of GTPγS with Arf-6 even in presence of cytohesin-1. The molecular docking analyses revealed that the galloyl group containing catechins (EGCG/ECG) with cytohesin1-Arf6GDP, but not the non-galloyl-containing catechins (EGC and EC), prevents GDP/GTP exchange in Arf-6 which seems to be an important mechanism for inhibition of ET-1 induced activation of PLD and subsequently increase in NADPH oxidase activities.

A sample of 44 male Type A insurance representatives, selected by means of the Videotaped Structured Interview, were randomly assigned to a treatment (n = 22) and a delayed treatment control group (n = 22). The treatment group participated in 9 weekly sessions of group Rational-Emotive Behavior Therapy and were followed up after 10 weeks. After the control period, the delayed treatment control group received the same treatment program. Repeated measurements were obtained by means of the Videotaped Structured Interview, Jenkins Activity Survey, Cook-Medley Hostility Scale, and Type A Cognitive Questionnaire. Self and spouse/friend ratings of Type A behavior were obtained by means of the Bortner Rating Scale. Analysis indicated that, compared to the control condition, the therapy significantly reduced the intensity of Type A behavior and its time urgency component. These improvements were maintained at follow-up and were accompanied by self-reports of significant positive changes in Type A behavior and irrational beliefs.

To test whether the addition of melatonin to bright-light therapy enhances the efficacy in treating rest-activity (circadian) disruption in institutionalized patients with Alzheimer's disease (AD). Randomized, controlled trial. Two nursing homes in San Francisco, California. Fifty subjects (mean age 86) with AD. Experimental subjects received 1 hour of morning light exposure (> or = 2,500 lux in gaze direction) Monday to Friday for 10 weeks and 5 mg melatonin (LM, n=16) or placebo (LP, n=17) in the evening. Control subjects (n=17) received usual indoor light (150-200 lux). Nighttime sleep variables, day sleep time, day activity, day:night sleep ratio, and rest-activity parameters were determined using actigraphy. Linear mixed models were employed to test the primary study hypotheses. No significant differences in nighttime sleep variables were found between groups. At the end of the intervention, the LM group showed significant improvement in daytime somnolence as indicated by a reduction in the duration of daytime sleep, an increase in daytime activity, and an improvement in day:night sleep ratio. The LM group also evidenced a significant increase in rest-activity rhythm amplitude and goodness of fit to the cosinor model. Light treatment alone did not improve nighttime sleep, daytime wake, or rest-activity rhythm. Light treatment plus melatonin increased daytime wake time and activity levels and strengthened the rest-activity rhythm. Future studies should resolve the question of whether these improvements can be attributed to melatonin or whether the two zeitgebers interact to amplify efficacy.

Previous analyses showed that a telephone-based intervention to increase physical activity in individuals with multiple sclerosis (MS) and depression resulted in significantly improved depressive symptoms compared to a wait-list control group. The aim of this study was to test positive affect and negative affect as mediators of the effect of the physical activity counseling on depressive symptoms. Ninety-two adults with MS, who met diagnostic criteria for either major depression or dysthymia and who reported low levels of physical activity, were randomized 1:1 to a 12-week telephone-based motivational interviewing (MI) intervention to improve physical activity (n = 44) or to a 12-week wait-list control group (n = 48). Self-reported positive and negative affect, physical activity, and depressive symptoms were gathered at baseline and postintervention. Path-analysis was used to test whether positive affect and negative affect mediated the positive effects of the intervention on depressive symptoms. Both positive and negative affect were significant mediators of the effects of the intervention on depressive symptoms; however, only positive affect mediated the association between changes in physical activity and improved depressive symptoms. Findings support physical activity and positive affect as key mediators of the MI treatment effect on improved mood. Decreases in negative affect were also evident in the treatment group, but were not related to improved physical activity. Findings may suggest the use of exercise-based interventions in conjunction with treatments that specifically target negative affective mechanisms for depression.

An educational approach based on a non-injury model compared with individual symptom-based physical training in chronic LBP. A pragmatic, randomised trial with a one-year follow-up

PubMed Central

2010-01-01

Background In the treatment of chronic back pain, cognitive methods are attracting increased attention due to evidence of effectiveness similar to that of traditional therapies. The purpose of this study was to compare the effectiveness of performing a cognitive intervention based on a non-injury model with that of a symptom-based physical training method on the outcomes of low back pain (LBP), activity limitation, LBP attitudes (fear-avoidance beliefs and back beliefs), physical activity levels, sick leave, and quality of life, in chronic LBP patients. Methods The study was a pragmatic, single-blind, randomised, parallel-group trial. Patients with chronic/recurrent LBP were randomised to one of the following treatments: 1. Educational programme : the emphasis was on creating confidence that the back is strong, that loads normally do not cause any damage despite occasional temporary pain, that reducing the focus on the pain might facilitate more natural and less painful movements, and that it is beneficial to stay physically active. 2. Individual symptom-based physical training programme : directional-preference exercises for those centralising their pain with repetitive movements; 'stabilising exercises' for those deemed 'unstable' based on specific tests; or intensive dynamic exercises for the remaining patients. Follow-up questionnaires (examiner-blinded) were completed at 2, 6 and 12 months. The main statistical test was an ANCOVA adjusted for baseline values. Results A total of 207 patients participated with the median age of 39 years (IQR 33-47); 52% were female, 105 were randomised to the educational programme and 102 to the physical training programme. The two groups were comparable at baseline. For the primary outcome measures, there was a non-significant trend towards activity limitation being reduced mostly in the educational programme group, although of doubtful clinical relevance. Regarding secondary outcomes, improvement in fear-avoidance beliefs was also better in the educational programme group. All other variables were about equally influenced by the two treatments. The median number of treatment sessions was 3 for the educational programme group and 6 for the physical training programme group. Conclusions An educational approach to treatment for chronic LBP resulted in at least as good outcomes as a symptom-based physical training method, despite fewer treatment sessions.

Paraquat (PQ) has been demonstrated that the main target organ for the toxicity is the lung. This study aimed to investigate the potential protective effect of PDTC on the PQ-induced pulmonary damage. Fifty-four rats were divided into control, PQ-treated and PQ+PDTC-treated groups. Rats in the PQ group were administrated 40 mg/kg PQ by gastric gavage, and PDTC group with 40 mg/kg PQ followed by injection of 120 mg/kg PDTC (IP). On the days 3, 7, 14 and 21 after treatments, the activities of GSH-Px, SOD, MDA level and the content of HYP were measured. TGF-β1 mRNA and protein were assayed by RT-PCR and ELISA. MDA level in plasma and BALF was increased and the activities of GSH-Px and SOD were decreased significantly in the PQ-treated groups (P < .05) compared with control group. While the activities of GSH-Px and SOD in the PQ+PDTC-treated groups was markedly higher than that of PQ-treated groups (P < .05), and in contrast, MDA level was lower. TGF-β1 mRNA and protein were significantly lower in the PQ+PDTC-treated groups than that of PQ-treated groups (P < .05). The histopathological changes in the PQ+PDTC-treated groups were milder than those of PQ groups. Our results suggested that PDTC treatment significantly attenuated paraquat-induced pulmonary damage.

This was a randomised, double-blind, placebo-controlled study to evaluate the efficacy and safety of Vitamin C vaginal tablets (250 mg) given once a day in patients suffering from non-specific vaginitis. The total length of the study was 20 days, including a treatment phase of 6 days. The primary end-point was the presence in the two groups of non-specific vaginitis 1 and 2 weeks after the end of treatment, as assessed by at least 3 out of the 4 characteristic symptoms: discharge, fishy odour, vaginal pH >/= 4.7, and presence of clue cells. Secondary end-points were the individual symptoms and signs, above reported, and pruritus, fever, superinfections, microscopic findings on vaginal smear, and colposcopy. One hundred female patients aged 18 years or older and suffering from non-specific vaginitis were included in the study after giving their informed consent. Fifty were randomised to the active treatment and 50 to placebo. Seven patients, three in the Vitamin C group and four in the placebo group, were lost to follow-up and did not complete the treatment period. Two patients in the active group showed protocol deviations (age under 18 years and HIV-positive, respectively). The two groups resulted comparable for demographics, history and baseline clinical picture. A cluster analysis of the four main symptoms showed a statistically significant difference between the active group and the placebo group; significantly more patients were still affected by non-specific vaginitis after placebo (35.7%) compared to patients treated with Vitamin C tablets (14.0%). The meaningful secondary variable, referring to the microscopic examination of vaginal smear, supported the trend for efficacy in the Vitamin C treated group. The clue cells disappeared in 79% of patients treated with the drug and in 53% of patients on placebo. Similarly, bacteria disappeared in 77 and 54%, respectively, while lactobacilli reappeared in 79.1 and 53.3%, respectively. Vaginal pH values decreased significantly in both groups, but the frequency rate of subjects with pH >/= 4.7, as measured 1 week after the drug discontinuation, was significantly lesser in the Vitamin C group (16.3%) than in the placebo group (38.6%). Adverse events occurred in four patients, two on placebo (pruritus, cystitis) and two on Vitamin C (two candidiasis).

To study the effect of leptin on the expression of calcium-activated neutral protease 1 (calpain-1) and B cell lymphoma-2 (Bcl-2) and apoptosis in the myocardial tissue of neonatal rats after asphyxia. A total of 48 neonatal rats were randomly and equally divided into normal control group, asphyxia group, leptin treatment groups, and calpain-1 inhibitor (CAI-1) group. The neonatal rat model of asphyxia under normal atmospheric condition was established in all groups except the control group. For the leptin treatment groups, rats received 20, 80, and 160 μg/kg leptin by intraperitoneal injection immediately after model establishment, respectively. For the CAI-1 group, rats received 10 mg/kg CAI-1 by intraperitoneal injection immediately after model establishment. For all the groups, the myocardial tissue was collected at 2 hours after model establishment. Immunohistochemistry was used to measure the expression of calpain-1 and Bcl-2. The TUNEL method was used to evaluate apoptosis of myocardial cells. The expression of calpain-1 and Bcl-2 and apoptosis index (AI) were significantly higher in the asphyxia group than in the normal control group (P˂0.05). The leptin treatment groups and the CAI-1 group had significantly lower expression of calpain-1, significantly lower AI, and significantly higher expression of Bcl-2 than the asphyxia group (P˂0.05). The CAI-1 group had the largest changes in all the indices compared with the asphyxia group. However, there were no significant differences in all indices between the 160 μg/kg leptin treatment group and the CAI-1 group. After asphyxia, the expression of calpain-1 was positively correlated with AI, while the expression of Bcl-2 was negatively correlated with AI and the expression of calpain-1 (P˂0.05). Leptin reduces apoptosis of myocardial cells in asphyxiated neonatal rats by the inhibition of calpain-1 activation and upregulation of Bcl-2 expression.

Modifying diet, exercise, sunlight exposure and sleep patterns may be useful in the treatment of depression. Eighty nonseasonal depressive outpatients on anti-depressant treatment were randomly assigned either to the active or control group. Four hygienic-dietary recommendations were prescribed together. Outcome measures were blinded assessed before and after the six month intervention period. A better evolution of depressive symptoms, a higher rate of responder and remitters and a lesser psychopharmacological prescription was found in the active group. Small sample size. Lacked homogeneity concerning affective disorders (major depression, dysthimia, bipolar depression). This study suggests lifestyle recommendations can be used as an effective antidepressant complementary strategy in daily practice. Copyright © 2012 Elsevier B.V. All rights reserved.

The protective effect of black cumin (Nigella sativa = NS) on cadmium-induced oxidative stress was studied in rats. The rats were randomly divided into three experimental groups: A (conrol), B (Cd treated), and C (Cd + NS treated), each containing 10 animals. The Cd-treated and Cd + NS-treated groups were injected subcutaneously daily with CdCl2 dissolved in isotonic NaCl in the amount of 2 mL/kg for 30 d, resulting in a dosage of 0.49 mg Cd/kg/d. The control group was injected with only isotonic NaCl (2 mL/kg/d) throughout the experiment (for 30 d). Three days prior to induction of CdCl2, the Cd + NS-treated group received a daily intraperitoneal injection of 0.2 mL/kg NS until the end of the study. Cd treatment increased significantly the malondialdehyde levels in plasma and erythrocyte (p<0.01 and p<0.05, respectively) and also increased significantly the antioxidant levels (superoxide dismutase, glutathione peroxidase, and catalase) (p<0.05) compared to the control group. Cd + NS treatment decreased significantly the elevated malondialdehyde levels in plasma and erythrocyte (p<0.01 and p<0.05, respectively) and also reduced significantly the enhanced antioxidant levels (p<0.05). Cd treatment increased significantly the activity of iron levels (p<0.05) in the plasma compared to the control group. Cd + NS treatment decreased the activity of iron levels (p<0.05) in the plasma compared to the Cd-treated group. In the control group with no treatment, histology of erythrocytes was normal. In the Cd-treated group, there were remarkable membrane destruction and hemolytic changes in erythrocytes. In the Cd + NS-treated group, these changes were less than in the Cd-treated group. Our results show that N. sativa exerts a protective effect against cadmium toxicity.

Prehypertension has been associated with adverse cerebrovascular events and brain damage. The aims of this study were to investigate ⅰ) whether short‑ and long-term treatments with losartan or amlodipine for prehypertension were able to prevent blood pressure (BP)-linked brain damage, and ⅱ) whether there is a difference in the effectiveness of treatment with losartan and amlodipine in protecting BP-linked brain damage. In the present study, prehypertensive treatment with losartan and amlodipine (6 and 16 weeks treatment with each drug) was performed on 4-week‑old stroke-prone spontaneously hypertensive rats (SHRSP). The results showed that long-term (16 weeks) treatment with losartan is the most effective in lowering systolic blood pressure in the long term (up to 40 weeks follow-up). Additionally, compared with the amlodipine treatment groups, the short‑ and long-term losartan treatments protected SHRSP from stroke and improved their brains structurally and functionally more effectively, with the long-term treatment having more benefits. Mechanistically, the short‑ and long-term treatments with losartan reduced the activity of the local renin-angiotensin-aldosterone system (RAAS) in a time-dependent manner and more effectively than their respective counterpart amlodipine treatment group mainly by decreasing AT1R levels and increasing AT2R levels in the cerebral cortex. By contrast, the amlodipine treatment groups inhibited brain cell apoptosis more effectively as compared with the losartan treatment groups mainly through the suppression of local oxidative stress. Taken together, the results suggest that long-term losartan treatment for prehypertension effectively protects SHRSP from stroke-induced brain damage, and this protection is associated with reduced local RAAS activity than with brain cell apoptosis. Thus, the AT1R receptor blocker losartan is a good candidate drug that may be used in the clinic for long-term treatment on prehypertensive populations in order to prevent BP-linked brain damage.

Understanding the Impact of Treatment on the Dimensions of Childhood Depression.

Childhood depression is often chronic and recurrent, with only modest improvements after optimal treatments. Novel approaches are needed for accurate diagnosis, timely selection of the best treatment for childhood depression, and improvement of remission rates. An important part of diagnosis is to determine how many consistent dimensions underlie childhood depression and what impact treatment may have on these dimensions. The goal of the current study is evaluate the consistency of the number of depressive symptom dimensions and examine the effect of depression treatment on the change in dimensions by seeing if this dimensional structure is the same for groups that were given a placebo and groups that were given an active drug, fluoxetine. We examined a combined sample of three clinical trials data sets with a total of 269 placebo patients and 261 fluoxetine patients at baseline, and 253 placebo patients and 249 fluoxetine patients at exit. Principal components analysis with associated parallel analysis followed by a ProMax oblique rotation was conducted on each week's scores. The similarity of the rotated structures between treatments and between weeks was then assessed using Wrigley and Neuhaus' (1955) degree of factorial similarity measure, which is a correlation-like statistic that takes two solutions based upon the same measures and assesses how similar they are. Preliminary analysis indicated that mean scores of both treatment groups declined from baseline to exit, but the decline was greater for the fluoxetine group. There were four dimensions at baseline and two dimensions at exit in each treatment group. Hence the numbers of dimensions were the same in the two groups, whereas the content of the components was the same at baseline for the two groups, but was different at exit. Basically, the factorial similarities of the rotated factors were very high at baseline between the two groups for both factors (Ψ = 0.97 for factor I and 0.94 for factor II) before they were treated differently. However, at exit, the respective similarities dropped to 0.58 and -0.04 for factors I and II. Therefore, time had a large effect in changing both groups' factor structure, but it was especially large when there was an active treatment. In comparing the baseline and exit dimensions in a forced two factor solution of two treatment groups, it was revealed that treatment did have an impact on the change in dimensions. These results further the generality of the simplification of the factor structure of the Childhood Depression Rating Scale- Revised (CDRS-R) over time. In addition, these results show the effect of time and therapy on the factor structures. The fluoxetine group followed the trend of the content of the dimensions revealed in a previous study, whereas the placebo group had a less distinct change over time.

Background and Objectives Low level laser (light) therapy (LLLT) has been demonstrated to promote hair growth in males. A double-blind randomized controlled trial was undertaken to define the safety and physiologic effects of LLLT on females with androgenic alopecia. Methods Forty-seven females (18–60 years old, Fitzpatrick I–IV, and Ludwig–Savin Baldness Scale I-2, I-3, I-4, II-1, II-2 baldness patterns) were recruited. A transition zone scalp site was selected; hairs were trimmed to 3 mm height; the area was tattooed and photographed. The active group received a “TOPHAT655” unit containing 21, 5 mW diode lasers (655 ± 5 nm) and 30 LEDS (655 ± 20 nm), in a bicycle-helmet like apparatus. The placebo group unit appeared identical, containing incandescent red lights. Patients treated at home every other day × 16 weeks (60 treatments, 67 J/cm2 irradiance/25 minute treatment, 2.9 J dose), with follow up and photography at 16 weeks. A masked 2.85 cm2 photographic area was evaluated by another blinded investigator. The primary endpoint was the percent increase in hair counts from baseline. Results Forty-two patients completed the study (24 active, 18 sham). No adverse events or side effects were reported. Baseline hair counts were 228.2 ± 133.4 (N = 18) in the sham and 209.6 ± 118.5 (N = 24) in the active group (P = 0.642). Post Treatment hair counts were 252.1 ± 143.3 (N = 18) in the sham group and 309.9 ± 166.6 (N = 24) in the active group (P = 0.235). The change in hair counts over baseline was 23.9 ± 30.1 (N = 18) in the sham group and 100.3 ± 53.4 (N = 24) in the active group (P < 0.0001). The percent hair increase over the duration of the study was 11.05 ± 48.30 (N = 18) for the sham group and 48.07 ± 17.61 (N = 24) for the active group (P < 0.001). This demonstrates a 37% increase in hair growth in the active treatment group as compared to the placebo group. Conclusions LLLT of the scalp at 655 nm significantly improved hair counts in women with androgenetic alopecia at a rate similar to that observed in males using the same parameters. Lasers Surg.

To determine the efficacy of polydeoxyribonucleotide (PDRN) injection for rotator cuff disease (RCD). Case-controlled, retrospective, comparative study. Outpatient clinic at a university-affiliated tertiary care hospital. Patients (N=106) with chronic nontraumatic refractory RCD who were unresponsive to at least 1 month of conservative treatment: 55 patients received PDRN injection (PDRN group) and 51 continued conservative treatment (control group). Not applicable. Shoulder Pain and Disability Index, score on a visual analog scale of the average shoulder pain level, number of analgesic ingestions per day, isometric strength of shoulder abductor, active range of motion (flexion, abduction, internal rotation, external rotation), and maximal tear size of tendon on ultrasonography at pretreatment and 3 and 6 months postinjection. There was no significant difference between the 2 groups in terms of age, sex, shoulder affected, duration of symptoms, and ultrasonographic findings at pretreatment. Compared with the control group, the treatment group showed a significant improvement in Shoulder Pain and Disability Index, visual analog scale score, and number of analgesic ingestions per day. However, there was no difference in isometric strength, active range of motion, and maximal tear size of tendon. No adverse events were reported. To our knowledge, this is the first study to assess the efficacy of PDRN injection for patients with RCD. The PDRN injection group showed improvement in pain and subjective disability in patients with RCD and continued to show improvement for 3 months thereafter; the PDRN injection can be an optional treatment for patients with chronic RCD who show no response to other treatments.

The aim of this study was to investigate the effects of Nintendo Wii(TM)-based balance and upper extremity training on activities of daily living and quality of life in patients with subacute stroke. 42 adults with stroke (mean age (SD) = 58.04 (16.56) years and mean time since stroke (SD) = (55.2 ± 22.02 days (∼8 weeks)) were included in the study. Participants were enrolled from the rehabilitation department of a medical center (a single inpatient rehabilitation facility). Participants were randomly assigned to Nintendo Wii group (n = 20) or Bobath neurodevelopmental treatment (NDT) (n = 22). The treatments were applied for 10 weeks (45-60 minutes/day, 3 days/week) for both of two groups. Nintendo Wii group used five games selected from the Wii sports and Wii Fit packages for upper limb and balance training, respectively. The patients in Bobath NDT group were applied a therapy program included upper extremity activites, strength, balance gait and functional training. The functional independence in daily life activities and health-related quality of life was assessed with Functional Independence Measure (FIM) and Nottingham Health Profile (NHP), respectively. Participant's treatment satisfaction was recorded by using Visual Analogue Scale. A second evaluation (FIM and NHP) occurred after 10 weeks at the end of rehabilitative treatment (post-training). Treatment satisfaction was measured after 10 sessions. There were significant difference between FIM and NHP values in NDT and Nintendo Wii group (p < 0.05). However, a significant difference was not found between the groups with regard to FIM and NHP (p > 0.05). The patients in Nintendo Wii group were detected to be better satisfied from the therapy (p < 0.05). A significant difference was found between subparameters and total FIM score, all subparameters and total NHP score in both groups (p < 0.05). These findings suggested that the Nintendo Wii training was as effective as Bobath NDT on daily living functions and quality of life in subacute stroke patients.

Observing the effects of a drug on episodic memory and the underlying brain function has extreme significance in evaluating its therapeutic value in treating amnestic mild cognitive impairment (aMCI). To observe the effects of Bushen capsule (BSC), a Chinese herbal medicine, on episodic memory in aMCI and further explore the underlying mechanism. 44 aMCI patients from hospitals and local communities in Beijing were randomly divided into the BSC treatment group (22 patients orally treated with BSC) and the placebo group (22 patients treated with placebo). The duration of intervention lasted for 3 months. Before and after the 3 months treatment, neuropsychological tests and fMRI examinations were carried out to assess cognitive ability and brain activation changes, respectively. Compared to the placebo group, the BSC group presented a significant increase in the AVLT(N5) (p = 0.003) and Stroop (C-B) time (p = 0.002). fMRI results showed a reduction of brain negative activation in the right middle temporal gyrus and a positive activation enhancement in the right putamen among the BSC group after treatment. Meanwhile, the variation in activation values in the right middle temporal gyrus was significantly correlated with the improvement in test values of AVLT(N5), and the variation in deactivation values in the right putamen was significantly correlated with the improvement in test values of Stroop (C-B) time. BSC can improve the behavioral performances of episodic memory in aMCI; this effect may be related to its modulation on the activations of the temporal lobe and the putamen under episodic memory encoding task.

Factor Xa (FXa) plays a critical role in the coagulation cascade by generation of thrombin. During focal ischemia thrombin levels increase in the brain tissue and cause neural damage. This study examined the hypothesis that administration of the FXa inhibitor, apixaban, following focal ischemic stroke may have therapeutic potential by decreasing brain thrombin activity and infarct volume. Male mice were divided into a treated groups that received different doses of apixaban (2, 20, 100 mg/kg administered I.P.) or saline (controls) immediately after blocking the middle cerebral artery (MCA). Thrombin activity was measured by a fluorescence assay on fresh coronal slices taken from the mice brains 24 hr following the MCA occlusion. Infarct volume was assessed using triphenyltetrazolium chloride staining. A high dose of apixaban (100 mg/kg) significantly decreased thrombin activity levels in the ipsilateral hemisphere compared to the control group (Slice#5, p = .016; Slice#6, p = .016; Slice#7, p = .016; Slice#8, p = .036; by the nonparametric Mann-Whitney test). In addition, treatment with apixaban doses of both 100 mg/kg (32 ± 8% vs. 76 ± 7% in the treatment vs. control groups respectively; p = .005 by the nonparametric Mann-Whitney test) and 20 mg/kg (43 ± 7% vs. 76 ± 7% in the treatment vs. control groups respectively; p = .019 by the nonparametric Mann-Whitney test) decreased infarct volumes in areas surrounding the ischemic core (Slices #3 and #8). No brain hemorrhages were observed either in the treated or control groups. In summary, I.P. administration of high dose of apixaban immediately after MCA occlusion decreases brain thrombin activity and reduces infarct size. © 2018 Wiley Periodicals, Inc.

Recently, it has been reported that losartan, an angiotensin II receptor (ATR) antagonist, depresses the angiotensin II-induced production of superoxide radicals. Also, in spontaneously hypertensive rats (SHR) endothelial dysfunction is associated with decreased nitric oxide (NO) synthesis. In this study, we examined the effects of long-term ATR blockade and L-arginine supplementation on the haemodynamic parameters, glomerular filtration, and oxidative status in SHR. Adult male SHR were treated with losartan (10 mg/kg) and with the NO donor L-arginine (2 g/kg) for 4 weeks. The animals were divided into the following experimental groups: control (n = 7), L-arginine (n = 7), losartan (n = 7), and L-arginine + losartan (n = 7). Mean arterial pressure (MAP), regional blood flow, urea clearance, and activity of superoxide dismutase (SOD) were measured at the end of treatment. MAP was significantly reduced in the losartan group compared with the control group (133.3 +/- 7.3 vs. 161.5 +/- 14.5 mm Hg). Aortic blood flow was significantly higher and aortic vascular resistance was significantly lower in all treated groups than in the control. Urea clearance rose significantly in the L-arginine + losartan group compared with control (393.27 +/- 37.58 vs. 218.68 +/- 42.03 microL x min(-1) x 100 g(-1)) as did the activity of SOD (1668.97 +/- 244.57 vs. 1083.18 +/- 169.96 U/g Hb). Our results suggest that the antihypertensive effect of losartan and L-arginine in SHR is not primarily mediated by increased SOD activity. Also, combined treatment with ATR blockade and L-arginine supplementation has a beneficial effect on renal function that is, at least in part, mediated by increased SOD activity in SHR.

Two types of bead-form macroporous carriers based on glycidyl methacrylate with ethylene dimethacrylate copolymers were used for the immobilization of penicillin amidase either directly or after chemical modification. Direct binding through oxirane groups, which is equally efficient at pH 4.2 and 7, is relatively slow and brings about an activity loss at low enzyme concentrations. The most efficient immobilization was achieved on glutaraldehyde-activated amino carrier, irrespective of whether the amino groups were formed by ammonia or 1,6-diaminohexane treatment of the original oxirane carrier. Hydrazine treatment gave lower immobilization yields. The same is true of the azide method independent of the length of the spacer. Most enzyme activity was preserved by coupling the carbodiimide-activated enzyme to the carrier with alkyl or arylamino groups at the end of a longer substituent. Immobilization on diazo-modified carrier gave average results. Rapid immobilization by a lysine-modified phosgene-treated carrier resulted in an activity loss. It is suggested that multipoint and very tight attachment of the enzyme molecule to the matrix decreased the activity. The immobilized activity is quite stable in solution and very stable upon lyophilization with sucrose.

To compare the efficiency of transcutaneous electrical nerve stimulation (TENS) with those of exercise and acetaminophen for the treatment of pregnancy-related low back pain (LBP) during the third trimester of pregnancy. This prospective study included 79 subjects (≥32 gestational weeks) with visual analog scale (VAS) pain scores ≥5. Participants were divided randomly into a control group (n = 21) and three treatment groups [exercise (n = 19); acetaminophen (n = 19); TENS (n = 20)]. The VAS and the Roland-Morris disability questionnaire (RMDQ) were completed before and 3 weeks after treatment to assess the impact of pain on daily activities. During the study period, pain intensity increased in 57% of participants in the control group, whereas pain decreased in 95% of participants in the exercise group and in all participants in the acetaminophen and TENS groups. Post-treatment VAS and RMDQ values were significantly lower in the treatment groups (p < 0.001). VAS and RMDQ scores indicated a significantly greater degree of pain relief in the TENS group than in the exercise and acetaminophen groups (p < 0.001). No adverse effect of TENS application on pregnant women was observed during the study. TENS is an effective and safe treatment modality for LBP during pregnancy. TENS improved LBP more effectively than did exercise and acetaminophen. Copyright © 2012 S. Karger AG, Basel.

To compare the effectiveness of single dose activated charcoal, single dose activated charcoal with sorbitol, and multidose activated charcoal in reducing plasma carprofen concentrations following experimental overdose in dogs. Randomized, four period cross-over study. University research setting. Eight healthy Beagles. A 120 mg/kg of carprofen was administered orally to each dog followed by either (i) a single 2 g/kg activated charcoal administration 1 hour following carprofen ingestion (AC); (ii) 2 g/kg activated charcoal with 3.84 g/kg sorbitol 1 hour following carprofen ingestion (ACS); (iii) 2 g/kg activated charcoal 1 hour after carprofen ingestion and repeated every 6 hours for a total of 4 doses (MD); (iv) no treatment (control). Plasma carprofen concentrations were obtained over a 36-hour period following carprofen ingestion for each protocol. Pharmacokinetic modeling was performed and time versus concentration, area under the curve, maximum plasma concentration, time to maximum concentration, and elimination half-life were calculated and compared among the groups using ANOVA followed by Tukey's multiple comparisons test. Activated charcoal, activated charcoal with sorbitol (ACS), and multiple-dose activated charcoal (MD) significantly reduced the area under the curve compared to the control group. AC and MD significantly reduced the maximum concentration when compared to the control group. MD significantly reduced elimination half-life when compared to ACS and the control group. There were no other significant differences among the treatment groups. Activated charcoal and ACS are as effective as MD in reducing serum carprofen concentrations following experimental overdose in dogs. Prospective studies are warranted to evaluate the effectiveness of AC, ACS, and MD in the clinical setting. © Veterinary Emergency and Critical Care Society 2015.

ABSTRACT Background: Sugar alcohols such as xylitol are incorporated in a number of oral hygiene products for their anti-cariogenic properties while chewing gum is known to be beneficial to oral hygiene. Objective: The aim of this study was to determine the composition of the dental plaque microbiota in patients with active caries before and after using a chewing gum supplemented with maltitol. Design: Forty subjects with active caries were randomly allocated to chew maltitol gum or gum base for two weeks. A healthy control group used gum base for two weeks. Plaque samples were collected before and after treatment and the microbiota analysed by pyrosequencing of 16S rRNA genes. Results: A total of 773,547 sequences were obtained from 117 samples. There was no difference in structure of the bacterial communities between groups (AMOVA). There was a significant difference in community membership between groups, (AMOVA, p=0.009). There was a significant difference between the control group after treatment and the maltitol patient group after treatment (p<0.001). A. naeslundii HOT-176 and Actinomyces HOT-169 were significantly reduced following use of maltitol chewing gum in patients. Conclusions: This study has shown that chewing gum containing maltitol had minor effects on the composition of the plaque microbiome. PMID:29081913

Visuospatial neglect (VSN) is devastating and common after stroke, and is thought to involve functional disturbance of the attention network. Non-invasive theta-burst stimulation (TBS) may help restore the normal function of attention network, therefore facilitating recovery from VSN. This study investigated the effects of continuous TBS on resting-state functional connectivity (RSFC) in the attention network, and behavioral performances of patients with VSN after stroke. Twelve patients were randomly assigned to receive 10-day cTBS of the left posterior parietal cortex delivered at 80% (the cTBS group), or 40% (the active control group) of the resting motor threshold. Both groups received daily visual scanning training and motor function treatment. Resting-state functional MRI (fMRI) and behavioral tests including line bisection test and star cancelation test were conducted at baseline and after the treatment. At baseline, the two groups showed comparable results in the resting-state fMRI experiments and behavioral tests. After treatment, the cTBS group showed lower functional connectivity between right temporoparietal junction (TPJ) and right anterior insula, and between right superior temporal sulcus and right anterior insula, as compared with the active control group; both groups showed improvement in the behavioral tests, with the cTBS group showing larger changes from baseline than the active control group. cTBS of the left posterior parietal cortex in patients with VSN may induce changes in inter-regional RSFC in the right ventral attention network. These changes may be associated with improved recovery of behavioral deficits after behavioral training. The TPJ and superior temporal sulcus may play crucial roles in recovery from VSN.

A prospective, double-blind, randomized, and controlled trial was conducted in patients with knee osteoarthritis (OA) to evaluate the efficacy of infrared low-power Gallium-Arsenide (Ga-As) laser therapy (LPLT) and compared two different laser therapy regimes. Ninety patients were randomly assigned to three treatment groups by one of the nontreating authors by drawing 1 of 90 envelopes labeled 'A' (Group I: actual LPLT consisted of 5 minutes, 3 J total dose + exercise; 30 patients), 'B' (Group II: actual LPLT consisted of 3 minutes, 2 J total dose + exercise; 30 patients), and 'C' (Group III: placebo laser group + exercise; 30 patients). All patients received a total of 10 treatments, and exercise therapy program was continued during study (14 weeks). Subjects, physician, and data analysts were unaware of the code for active or placebo laser until the data analysis was complete. All patients were evaluated with respect to pain, degree of active knee flexion, duration of morning stiffness, painless walking distance and duration, and the Western Ontario and Mc Master Universities Osteoarthritis Index (WOMAC) at week 0, 6, 10, and 14. Statistically significant improvements were indicated in respect to all parameters such as pain, function, and quality of life (QoL) measures in the post-therapy period compared to pre-therapy in both active laser groups (P < 0.01). Improvements in all parameters of the Group I and in parameters, such as pain and WOMAC of the Group II, were more statistically significant when compared with placebo laser group (P < 0.05). Our study demonstrated that applications of LPLT in different dose and duration have not affected results and both therapy regimes were a safe and effective method in treatment of knee OA.

The present study describes a randomised controlled trial (RCT) based on a novel, generalisable intervention for childhood obesity, comparing the intervention with a no-treatment control group. The Malaysian Childhood Obesity Treatment Trial (MASCOT) was a single-blind RCT of a dietetic treatment for childhood obesity in children of primary school age (7 to 11 years old) in Kuala Lumpur, Malaysia. The MASCOT comprising eight sessions, of an 8-hour family-centred group treatment programme is described, based on behavioural change techniques. The study sample was characterised by BMI z-score, health related quality of life reported by participants and their parents (PedsQL questionnaire), objectively measured habitual physical activity and sedentary behaviour (Actigraph accelerometry) The MASCOT sample of 107 children was characterised by a low quality of life, mean total score on PedsQL 67.7 (4.5) as reported by the children, and 66.0 (16.4) as reported by their parents. The children spent, on average, 89% of their waking day on sedentary activity, and 1% of the day in moderate-vigorous intensity physical activity, equivalent to only around 8 minutes/day. Obese children in the MASCOT study had an impaired quality of life, high levels of sedentary behaviour and very low levels of physical activity.

To evaluate the pain severity, the motor function of the upper limb and the quality of life in the patients of post-stroke shoulder pain treated with the touching-periosteum needling technique of the meridian muscle region theory. One hundred and six cases of post-stroke shoulder pain were randomized into an observation group and a control group, 53 cases in each one. In the observation group, the touching-periosteum needle technique and the rehabilitation training were used on the bases of the theory of meridian muscle region. The points were Jianyuci , Binaoci , Jianliaoci , Jianqianci , Quchi (LI 11), Shousanli (LI 10) and Waiguan (TE 5) on the affected side. The needles were inserted obliquely, at 45°degrees at those extra points to the tendon knots till the needle tips touching periosteum. The needles were manipulated to ensure the qi arrival and then retained for 30 min. The rehabilitation was applied, such as the anti-spasmodic posture, bridge-style movement on the bed, weight transition and balance training, joint activity maintenance training, passive and active movement of shoulder joint, the training for activities of daily living (ADL) and Bobath technique. In the control group, the routine acupuncture and the rehabilitation training were used. The acupints were Jianyu (LI 15), Binao (LI 14), Jianliao (TE 14), Jianqian (Extra), Quchi (LI 11), Shousanli (LI 10) and Waiguan (TE 5). The rehabilitation training was the same as the observation group. The treatment was given once every day, 6 treatments a week. After 20 treatments, the visual analogue scale (VAS), Fugl-Meyer (FMA) score and Barthel (MBI) score were adopted to evaluate the pain severity, the motor function of the upper limb and the ADL. The clinical therapeutic effects were evaluated in the two groups. The VAS scores were reduced after treatment as compared with those before treatment in the two groups, and FMA and MBI scores were all increased as compared with those before treatment, indicating the significant difference statistically ( P <0.05, P <0.01). After treatment, the improvements in the observation group were better than those in the control group (all P <0.05). The curative and remarkably effective rate was 69.8% (37/53) in the observation group, better than 47.2% (25/53) in the control group ( P <0.05). The touching-periosteum needling technique of the meridian muscle region theory obviously improves the pain severity, the motor function of the upper limb and the quality of life in patients of post-stroke shoulder pain. The therapeutic effects are better than the routine acupuncture.

The purpose of this study was to evaluate the effects of an additional, organized, and more intensive kinesiological treatment on "pure" motor abilities in preschool children. In the present study an experimental treatment was carried out on a sample of 37 preschool boys by applying kinesiological activities. The 60 minute treatment was applied over a period of one school year (9 months), twice a week. A control group of 31 boys were trained according to the regular program for preschool institutions. Treatment effects were assessed by 8 motor ability tests and 5 anthropometric measures. The significant differences between the groups, which were observed after the final measurement and compared to the initial one, proved that the kinesiological treatment had a positive impact on the general development of "pure" motor abilities. The most significant effect of experimental kinesiological treatment was the improvement in whole body force, flexibility and coordination of preschool boys. These findings, obtained only in one school year, point to the importance of physical exercise and the application of additional kinesiological activities with various modalities, to improve motor development, even morphological growth and development in preschool children. The effects of the perennial application of kinesiological activities, under the supervision of kinesiological professionals, could be beneficial and could form the basis for a better biological and motor development in older age.

We compared the efficacy and safety of preemptive vs postoperative dosing of lumiracoxib 400 mg in patients undergoing minor ambulatory arthroscopic knee surgery. Eligible patients were randomized to preemptive lumiracoxib, postoperative lumiracoxib, and placebo. The main efficacy parameter was pain intensity (PI) (0–100 mm visual analog scale) in the target knee upon movement, 2 hours after surgery. Other efficacy variables included PI in the target knee at rest and upon movement at 1, 3, 4, and 24 hours, time to first rescue medication intake. In the lumiracoxib preemptive and postoperative groups, the estimated treatment difference compared to placebo for primary endpoint was −4.0 (95% CI: −9, −1; p = 0.007) and −3.5 (95% CI: −8.5, 0; p = 0.052), respectively. There was no statistical significant difference between two active treatment groups (p = 0.602). Both preemptive and postoperative lumiracoxib resulted in significantly lower PI scores at rest and after movement at all time-points and no statistically significant difference was observed between the active treatments. Time to rescue medication intake was comparable for both active treatments. The proportion of adverse events was similar among all groups. We conclude that the efficacy of lumiracoxib 400 mg is not affected by the timing of administration (preemptive or postoperative). PMID:21197285

Analysis of connectivity in NeuCube spiking neural network models trained on EEG data for the understanding of functional changes in the brain: A case study on opiate dependence treatment.

PubMed

Capecci, Elisa; Kasabov, Nikola; Wang, Grace Y

2015-08-01

The paper presents a methodology for the analysis of functional changes in brain activity across different conditions and different groups of subjects. This analysis is based on the recently proposed NeuCube spiking neural network (SNN) framework and more specifically on the analysis of the connectivity of a NeuCube model trained with electroencephalography (EEG) data. The case study data used to illustrate this method is EEG data collected from three groups-subjects with opiate addiction, patients undertaking methadone maintenance treatment, and non-drug users/healthy control group. The proposed method classifies more accurately the EEG data than traditional statistical and artificial intelligence (AI) methods and can be used to predict response to treatment and dose-related drug effect. But more importantly, the method can be used to compare functional brain activities of different subjects and the changes of these activities as a result of treatment, which is a step towards a better understanding of both the EEG data and the brain processes that generated it. The method can also be used for a wide range of applications, such as a better understanding of disease progression or aging. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to measure the effects of transference interpretations (the assumed core active ingredient) in dynamic psychotherapy, using an experimental design. One hundred patients were randomly assigned to two groups. One group received dynamic psychotherapy over 1 year, with a moderate level of transference interpretations, while the other group received dynamic psychotherapy with no transference interpretations. The most common axis I disorders were depression and anxiety disorders. Forty-six patients fulfilled the general criteria for personality disorder. Seven experienced psychotherapists treated patients in both groups. Five full sessions from each treatment were rated by two evaluators with process measures in order to document treatment integrity. Outcome variables were the Psychodynamic Functioning Scales, Inventory of Interpersonal Problems Scale-Circumplex version, Global Assessment of Functioning Scale, and Symptom Checklist-90-R. Quality of Object Relations Scale (lifelong pattern) and personality disorders were preselected as possible moderators of treatment effects. Change was assessed using linear-mixed models. Clinically significant change was also calculated. The authors could not demonstrate differential treatment effects between the groups. However, the moderator analyses showed that transference interpretations were more helpful for patients with a lifelong history of less mature object relations. Small negative effects were observed for patients with mature object relations. The authors could not show differences in average effectiveness between treatments. However, the moderator analyses indicated that treatment worked through different active ingredients for different patients. Contrary to common expectation, patients with poor object relations profited more from therapy with transference interpretations than from therapy with no transference interpretations.
