Although mindfulness meditation interventions have recently shown benefits for reducing stress in various populations, little is known about their relative efficacy compared with relaxation interventions. This randomized controlled trial examines the effects of a 1-month mindfulness meditation versus somatic relaxation training as compared to a control group in 83 students (M age = 25; 16 men and 67 women) reporting distress. Psychological distress, positive states of mind, distractive and ruminative thoughts and behaviors, and spiritual experience were measured, while controlling for social desirability. Hierarchical linear modeling reveals that both meditation and relaxation groups experienced significant decreases in distress as well as increases in positive mood states over time, compared with the control group (p < .05 in all cases). There were no significant differences between meditation and relaxation on distress and positive mood states over time. Effect sizes for distress were large for both meditation and relaxation (Cohen's d = 1.36 and .91, respectively), whereas the meditation group showed a larger effect size for positive states of mind than relaxation (Cohen's d =.71 and .25, respectively). The meditation group also demonstrated significant pre-post decreases in both distractive and ruminative thoughts/behaviors compared with the control group (p < .04 in all cases; Cohen's d = .57 for rumination and .25 for distraction for the meditation group), with mediation models suggesting that mindfulness meditation's effects on reducing distress were partially mediated by reducing rumination. No significant effects were found for spiritual experience. The data suggest that compared with a no-treatment control, brief training in mindfulness meditation or somatic relaxation reduces distress and improves positive mood states. However, mindfulness meditation may be specific in its ability to reduce distractive and ruminative thoughts and behaviors, and this ability may provide a unique mechanism by which mindfulness meditation reduces distress.

Diabetes mellitus is associated with significant morbidity, mortality, and escalating health care costs. Research has consistently demonstrated the importance of glycaemic control in delaying the onset, and decreasing the incidence, of both the short-term and long-term complications of diabetes. Although glycaemic control is difficult to achieve and challenging to maintain, it is key to reducing negative disease outcomes. The aim of this study was to determine whether a nurse-led educational intervention alone or a nurse-led intervention using education and acceptance and commitment therapy (ACT) was effective in reducing hemoglobin A 1c (HbA 1c ) in people living with uncontrolled type 2 diabetes compared to usual care. Adults over the age of 18 years, with a confirmed diagnosis of type 2 diabetes and HbA 1c outside of the recommended range (4%-7%, 20-53 mmol/mol) for 12 months or more, were eligible to participate. Participants were randomised to either a nurse-led education intervention, a nurse-led education plus ACT intervention, or a usual care. One hundred and eighteen participants completed baseline data collection (N = 34 education group, N = 39 education plus ACT, N = 45 control group). An intention to treat analysis was used. A statistically significant reduction in HbA 1c in the education intervention group was found (P = .011 [7.48, 8.14]). At 6 months, HbA 1c was reduced in both intervention groups (education group -0.21 and education and ACT group -0.04) and increased in the control group (+0.32). A positive change in HbA 1c (HbA 1c reduced) was noted in 50 participants overall. Twice as many participants in the intervention groups demonstrated an improvement as compared to the control group (56% of the education group, 51% education plus ACT, and 24% control group. At 6 months post intervention, HbA 1c was reduced in both intervention groups with a greater reduction noted in the nurse-led education intervention. © 2017 John Wiley & Sons, Ltd.

Diets producing a high glycemic response result in exaggerated insulin secretion which induces hepatic lipogenesis, contributing to development of insulin resistance and fatty liver. Viscous dietary fibers blunt the postprandial rise in blood glucose, however their effect on type 2 diabetes and obesity are not entirely known. This study examined the effect of chronic consumption of the viscous, non-fermentable dietary fiber, hydroxypropyl methylcellulose (HPMC), on glucose control, insulin resistance and liver lipids in an obese diabetic rat model. Three groups of Zucker Diabetic Fatty (ZDF) rats were fed diets containing either 5% non-viscous cellulose (control), low viscosity HPMC (LV-HPMC) or high viscosity HPMC (HV- HPMC) for six weeks. Zucker lean littermates consuming cellulose served as a negative control. Markers of glucose control, including oral glucose tolerance test, glycated hemoglobin and urinary glucose, were measured as well as adiposity and the accumulation of liver lipids. The HPMC diets increased the viscosity of the small intestinal contents and reduced the postprandial rise in blood glucose. The food efficiency ratio was greater with HPMC feeding compared to the obese control and urinary excretion of glucose and ketone bodies was reduced. The two HPMC groups had lower glycated hemoglobin and kidney weights and a reduced area under the curve during a glucose tolerance test, indicating improved glucose control. Epididymal fat pad weight as percent of body weight was reduced in the HV-HPMC group compared to the obese control group. The HV-HPMC group also had lower concentrations of liver lipid and cholesterol and reduced liver weight. However, HV-HPMC feeding did not affect hepatic gene expression of SREBP-1c or FAS. Muscle concentration of acylcarnitines, a lipid intermediate in fatty acid β-oxidation, was not different between the HPMC groups and obese control, suggesting no change in muscle fatty acid oxidation by HPMC. Consumption of the viscous non-fermentable fiber HPMC decreased diabetic wasting, improved glucose control and reduced insulin resistance and fatty liver in a model of obesity with diabetes.

Although many pregnant women experience back pain, it has not considered an important health problem. No study has investigated the effects of a back-pain-reducing program (BPRP) during pregnancy for Korean women. The purpose of this study was to evaluate the effect of a program designed to reduce back pain in pregnant women. A non-equivalent control-group pretest-posttest design was used. Pregnant women who attended an antenatal clinic and experienced back pain during their pregnancy were included in an intervention group (n=29), and their intensity of back pain, functional limitation and anxiety were compared with women in a control group from another antenatal clinic (n=27). The data were collected at three time points: prior to intervention, and 6 and 12 weeks after intervention. At 12 weeks after intervention, the intensity of back pain experienced by the intervention group was significantly lower than that of the control group. However, there were no statistically significant differences between the groups with respect to functional limitations and anxiety. The findings show that the pain-reducing program developed for this study was effective in reducing the intensity of back pain experienced by pregnant women. Promoting good posture and regular exercise can be recommended as a method to relieve back pain in pregnancy women. Further studies are needed to confirm the effect of the BPRP during pregnancy.

Pain on propofol injection is a limitation of propofol. So far, there has been no study about valsalva to reduce pain on propofol injection. Valsalva reduces pain via sinoaortic baroreceptor reflex arc and distraction both. We planned this study for assessing efficacy of Valsalva maneuver to reduce pain on propofol injection. Eighty American Society of Anesthesiologists grade I enrolled adult patients undergoing general anesthesia were divided into 2 groups of 40 each. Group I (Valsalva): blew into sphygmomanometer tube and raised mercury column up to 30 mmHg for 20 seconds; Group II (Control): didn't blow. Immediately after intervention, patients were induced with 1% propofol. Pain was assessed using visual analog scale (VAS) scoring [0-10; where 0 as no pain and 10 as worst imaginable pain] and Withdrawal response scoring [0-3; where 0 as no pain and 3 as worst pain] and presented as Median [interquartile range]. Seventy patient's data were analyzed. Incidence of pain was significantly reduced in Valsalva group (53% i.e. 18 out of 34) in comparison to control (78% i.e. 28 out of 36) (P < 0.05). Withdrawal response score was significantly reduced in the Valsalva group (1 [0.00]) as compared to control (2 [1.00]) (P < 0.05). VAS was significantly reduced in the Valsalva group (3.50 [1.25]) as compared to control (7 [1.00]) (P < 0.05). Valsalva performed before propofol induction is effective in attenuating propofol pain with an advantage of being non- pharmacological, safe, easy and time effective.

Purpose. Aromatherapy massage is an alternative treatment in reducing the pain of the cancer patients. This study was to investigate whether aromatherapy massage could improve the pain of the cancer patients. Methods. We searched PubMed and Cochrane Library for relevant randomized controlled trials without language limitations between 1 January 1990 and 31 July 2015 with a priori defined inclusion and exclusion criteria. The search terms included aromatherapy, essential oil, pain, ache, cancer, tumor, and carcinoma. There were 7 studies which met the selection criteria and 3 studies were eventually included among 63 eligible publications. Results. This meta-analysis included three randomized controlled trials with a total of 278 participants (135 participants in the massage with essential oil group and 143 participants in the control (usual care) group). Compared with the control group, the massage with essential oil group had nonsignificant effect on reducing the pain (standardized mean difference = 0.01; 95% CI [-0.23,0.24]). Conclusion. Aromatherapy massage does not appear to reduce pain of the cancer patients. Further rigorous studies should be conducted with more objective measures.

To study the role of CYP2E1 in the protective effects and mechanism of garlic oil (GO) on the peripheral nerve injuries induced by n-hexane. Fifty male Wistar rats were randomly divided into five groups (n = 10): the control, the GO (80 mg/kg) control, the n-hexane (2000 mg/kg) model, the low dose GO (40 mg/kg) plus n-hexane, and the high dose GO (80 mg/kg) plus n-hexane groups. All rats were treated by intragastric administration 6 times a week for 10 weeks. The gait scores were determined every two weeks for monitoring the peripheral neurotrosis. All rats were sacrificed in 10 weeks, the activities and expression levels of hepatic CYP2E1 and 2, 5-HD in serum were examined. As compared with control group, the content and activity of hepatic CYP2E1 in GO control group reduced by 83.1% and 48.3% respectively (P < 0.01), the content and activity of hepatic CYP2E1 in model group increased by 112.5% and 72.2% respectively (P < 0.01). As compared with model group, the contents of hepatic CYP2E1 in low dose and high dose GO groups reduced by 32.9% and 39.1% respectively, the activities of hepatic CYP2E1 in low dose and high dose GO groups reduced by 27.4% and 44.5% respectively (P < 0.01); the contents of serum 2,5-HD in low dose and high dose GO groups reduced by 47.7% and 78.7% respectively (P < 0.01). The gait scores in model, low dose and high dose GO groups were significantly lower than that in control group, but the gait scores in low dose and high dose GO groups were significantly lower than that in model group (P < 0.05). Garlic oil can effectively reduce the peripheral neurotrosis induced by n-hexane due to the decreased content and activity of hepatic CYP2E1, resulting in the reduced formation of 2, 5-HD from n-hexane.

To explore the effectiveness of a psycho-educational family intervention program for reducing burden in caregivers of patients with schizophrenia in a developing country. Forty-five caregivers participated, 22 in a psycho-educational family intervention group and 23 in a control group. The family program was held once a week for 5 months. In the control group the caregivers received standard intervention, comprising periodical meetings with the staff to monitor the effects of the medication. Burden was measured before and after the intervention: relatives in the psycho-educational group were evaluated at inclusion and at the end of the program; controls were evaluated at inclusion and 5 months later. Burden decreased significantly in the psycho-educational group; mean scores on the Zarit Caregiver Burden Scale fell from 85.06 pre-intervention to 52.44 post-intervention, while scores fell only slightly in the control group, from 87.65 to 87.22. Treatment was especially effective in mothers and caregivers with lower educational levels. This intervention program for reducing caregiver burden in developing Latin American countries was effective. Future investigations should focus on obtaining more precise estimates of the contributions of specific components of these programs to reducing burden.

A single flexible sigmoidoscopy at around the age of 60 years has been proposed as an effective strategy for colorectal cancer (CRC) screening. We conducted a randomized controlled trial to evaluate the effect of flexible sigmoidoscopy screening on CRC incidence and mortality. A questionnaire to assess the eligibility and interest in screening was mailed to 236,568 men and women, aged 55-64 years, who were randomly selected from six trial centers in Italy. Of the 56,532 respondents, interested and eligible subjects were randomly assigned to the intervention group (invitation for flexible sigmoidoscopy; n = 17,148) or the control group (no further contact; n = 17,144), between June 14, 1995, and May 10, 1999. Flexible sigmoidoscopy was performed on 9911 subjects. Intention-to-treat and per-protocol analyses were performed to compare the CRC incidence and mortality rates in the intervention and control groups. Per-protocol analysis was adjusted for noncompliance. A total of 34,272 subjects (17,136 in each group) were included in the follow-up analysis. The median follow-up period was 10.5 years for incidence and 11.4 years for mortality; 251 subjects were diagnosed with CRC in the intervention group and 306 in the control group. Overall incidence rates in the intervention and control groups were 144.11 and 176.43, respectively, per 100,000 person-years. CRC-related death was noted in 65 subjects in the intervention group and 83 subjects in the control group. Mortality rates in the intervention and control groups were 34.66 and 44.45, respectively, per 100,000 person-years. In the intention-to-treat analysis, the rate of CRC incidence was statistically significantly reduced in the intervention group by 18% (rate ratio [RR] = 0.82, 95% confidence interval [CI] = 0.69 to 0.96), and the mortality rate was non-statistically significantly reduced by 22% (RR = 0.78; 95% CI = 0.56 to 1.08) compared with the control group. In the per-protocol analysis, both CRC incidence and mortality rates were statistically significantly reduced among the screened subjects; CRC incidence was reduced by 31% (RR = 0.69; 95% CI = 0.56 to 0.86) and mortality was reduced by 38% (RR = 0.62; 95% CI = 0.40 to 0.96) compared with the control group. A single flexible sigmoidoscopy screening between ages 55 and 64 years was associated with a substantial reduction of CRC incidence and mortality.

This article reports a study to evaluate the efficacy of a self-help manual in reducing psychological distress in individuals with moderate depression. The prevalence of depression in Thailand is increasing markedly (e.g. from 56-197 per 100,000 population between 1997-2007). We conducted a randomized controlled trial with 54 outpatients with depression in Chiang Mai Province in Thailand. Participants were assigned randomly to an intervention or control group. The intervention group participants were given a self-help manual in addition to standard care and treatment while the control group received standard care and treatment. Psychological distress was measured with the Kessler Psychological Distress Scale. Data were collected between October 2007-April 2008. The findings showed statistically significant differences between both groups in their levels of psychological distress (e.g. tiredness, hopelessness, restlessness). At post-test, the distress scores of the intervention group were lower than those in the control group. Between post-test and 1-month follow-up, distress scores continued to decrease steadily in the intervention group but only decreased slightly in the control group. The findings affirm the benefits of bibliotherapy or self-help therapy in book form in helping to reduce psychological distress in people with moderate depression. The approach is easy to use and can be incorporated as an adjunct to standard care and treatment. Bibliotherapy can be used by community mental health nurses and other clinicians to reduce psychological distress and promote recovery in people with moderate depression. © 2012 Blackwell Publishing Ltd.

To observe the clinical efficacy of modified Da Chaihu decoction in treating essential hypertension with anxiety, the randomized, controlled, clinical trial was performed in this study. One hundred and twenty-six hypertensive patients with anxiety meeting the inclusive criteria were randomized into the treatment group and the control group. All of the included patients in the above 2 groups were treated by amlodipine besylate tablets. Patients in the treatment group were given Chinese herbal medicine modified Da Chaihu decoction every day. And patients in the control group were given flupentixol and melitracen tablets. The treatment course was 4 weeks. Blood pressure, the score of traditional Chinese medicine syndrome, blood lipids, C reactive protein, the Hamilton anxiety scale score and adverse effects were observed. It has been identified that, both systolic and diastolic blood pressure were significantly reduced (P<0.05). However, no significant difference between the treatment group and the control group was identified. For traditional Chinese medicine syndrome, it was significantly improved in the treatment group (P<0.05). For blood lipids, TC, TG, HDL-C, and LDL-C were significantly improved in the treatment group (P<0.05). After treatment, only TC was significantly reduced in the treatment group when compared to the control group (P<0.05). For C reactive protein, it was significantly reduced in the treatment group after treatment (P<0.05). For anxiety, no significant difference between the treatment group and the control group on the Hamilton anxiety scale score was identified. For adverse effect, no severe adverse effect was identified in this study. The modified Da Chaihu decoction maybe effective in the treatment of essential hypertension with anxiety. In addition to a certain role in lowering blood pressure, the modified Da Chaihu decoction was also effective in improving traditional Chinese medicine syndrome and blood lipids, reducing the level of C reactive protein, relieving anxiety with little adverse effect.

To investigate the effect of a special gynaecological garment and music plus the special gynaecological garment on reducing the state anxiety related to gynaecological examination. Gynaecological examination is one of the most common anxiety-producing medical procedures and causes embarrassment and discomfort. Few studies have focused on the effect of a gynaecological garment on anxiety associated with gynaecological examinations. The patients were allocated to one of three groups, one control and two experimental. While the patients in the control group were subjected to the normal outpatient procedure, the patients in the first experimental group were dressed in a special gynaecological garment. In the control group, gynaecological examinations were performed with a traditional one-piece drape. In addition to wearing the special gynaecological garment, the women in the garment + music group listened to music during the gynaecological examination. The State Anxiety Inventory Form was applied to the patients in all three groups before and after gynaecological examination. The state anxiety level after gynaecological examination in patients in the control group was found to be higher, but it was found to be lower in patients in both the first experimental group (garment) and the second experimental group (garment + music). The state anxiety level was found to be more reduced in the experimental groups than in the control group. The state anxiety level after gynaecological examination was found to be higher in single patients in the second experimental group. The special gynaecological garments are effective in reducing the state anxiety associated with gynaecological examination. It should be taken into consideration that women perceived state anxiety during the gynaecological examinations. To allay anxiety associated with gynaecological examination in women, a special garment may be considered. © 2011 Blackwell Publishing Ltd.

The aim of this study is to determine the effect of dietary pitamin as an antibiotic replacement in broiler chicken. The treated groups were as follows: 1) the control, 2) the antibiotics (8 mg of avilamycin kg(-1) of diet) and 3) the pitamin (70 mg of pitamin kg(-1) of diet) groups. Body weight gain, feed intake, and feed efficiency were significantly higher in the pitamin group than in the antibiotics and control groups (p<0.05). Carcass weight, dressing percentage, and the weight of breast and thigh muscle recorded significantly higher levels in the pitamin group as compared to the other groups (p<0.05). The addition of pitamin to the diets for broilers reduced abdominal fat by 23.35% and stimulated the growth of the thymus, the spleen, and the bursa of Fabricius. TAG levels of the pitamin group declined by 12.03 and 10.45% as compared to the control and antibiotics groups, and their TC levels were reduced by 15.17 and 14.39%, and LDL. C levels were reduced by 10.56 and 11.24%, respectively. Serum IgG was increased significantly by 137.43 and 36.80% in the pitamin group as compared to the control and antibiotics groups, respectively (p<0.05). The numbers of Bifidobacterium and Lactobacillus on the cecum digesta were significantly higher in the pitamin group than in the antibiotics and control groups and the numbers of Escherichia coli and Salmonella tended to be reduced (p<0.05). In conclusion, when Korean red pine bark extract, pitamin, was added to the broiler diets at a concentration of 70 mg of pitamin kg(-1) of diet, it resulted in better growth performance as compared to the antibiotics by improving immunity and the cecal beneficial microfloral population.

This study was conducted to determine the effect of cognitive-behavioral stress management (CBT) on reducing psychological stress in diabetic pregnant women. This randomized controlled trial applied through pretest and post-test with control group was conducted on 88 eligible women with gestational diabetes. Women who had a stress score more than 15, randomly assigned to intervention or control groups. Intervention group received stress management training within six two-hour sessions for three weeks. Stress and FBS were measured before intervention and two weeks after the last session. Data were analyzed using the SPSS version 19.0. Results were analyzed using chi-square, paired t test and independent sample t test. In CBT training group, stress significantly decreased two weeks after the training (p < 0.001). In the control group, the stress scores were significantly different before and after the intervention and women had a significant increase in the stress scores (p = 0.028). There was a significant difference between two groups in stress scores, two weeks after intervention (p = 0.001). Cognitive-behavioral stress management reduces stress in women with gestational diabetes and reducing stress may also improve the pregnancy outcomes, especially whose glycemic along with stress is not adequately controlled by medication.

This prospective pilot study was undertaken to evaluate the feasibility and effectiveness of using a radiation absorbing shield to reduce operator dose from scatter during lower limb endovascular procedures. A commercially available bismuth shield system (RADPAD) was used. Sixty consecutive patients undergoing lower limb angioplasty were included. Thirty procedures were performed without the RADPAD (control group) and thirty with the RADPAD (study group). Two separate methods were used to measure dose to a single operator. Thermoluminescent dosimeter (TLD) badges were used to measure hand, eye, and unshielded body dose. A direct dosimeter with digital readout was also used to measure eye and unshielded body dose. To allow for variation between control and study groups, dose per unit time was calculated. TLD results demonstrated a significant reduction in median body dose per unit time for the study group compared with controls (p = 0.001), corresponding to a mean dose reduction rate of 65 %. Median eye and hand dose per unit time were also reduced in the study group compared with control group, however, this was not statistically significant (p = 0.081 for eye, p = 0.628 for hand). Direct dosimeter readings also showed statistically significant reduction in median unshielded body dose rate for the study group compared with controls (p = 0.037). Eye dose rate was reduced for the study group but this was not statistically significant (p = 0.142). Initial results are encouraging. Use of the shield resulted in a statistically significant reduction in unshielded dose to the operator's body. Measured dose to the eye and hand of operator were also reduced but did not reach statistical significance in this pilot study.

Pivoting neuromuscular control and proprioceptive acuity may play an important role in anterior cruciate ligament injuries. The goal of this study was to investigate whether pivoting off-axis intensity adjustable neuromuscular control training (POINT) could improve pivoting neuromuscular control, proprioceptive acuity, and functional performance. Among 41 subjects, 21 subjects participated in 18 sessions of POINT (three sessions per week for 6 wk), and 20 subjects served as controls who did their regular workout. Both groups received pre-, mid-, and postintervention evaluations. Propensity score analysis with multivariable regression adjustment was used to investigate the effect of training on pivoting neuromuscular control (pivoting instability, leg pivoting stiffness, maximum internal, and external pivoting angles), proprioceptive acuity, and functional performance in both groups. Compared with the control group, the training group significantly improved pivoting neuromuscular control as reduced pivoting instability, reduced maximum internal and external pivoting angles, increased leg pivoting stiffness, and decreased entropy of time to peak EMG in the gluteus maximus and lateral gastrocnemius under pivoting perturbations. Furthermore, the training group enhanced weight-bearing proprioceptive acuity and improved the single leg hop distance. Improvement of pivoting neuromuscular control in functional weight-bearing activities and task performances after POINT may help develop lower limb injury prevention and rehabilitation methods to reduce anterior cruciate ligament and other musculoskeletal injuries associated with pivoting sports.

To investigate the efficacy of problem solving therapy for reducing the emotional distress experienced by younger stroke survivors. A non-randomized waitlist controlled design was used to compare outcome measures for the treatment group and a waitlist control group at baseline and post-waitlist/post-therapy. After the waitlist group received problem solving therapy an analysis was completed on the pooled outcome measures at baseline, post-treatment, and three-month follow-up. Changes on outcome measures between baseline and post-treatment (n = 13) were not significantly different between the two groups, treatment (n = 13), and the waitlist control group (n = 16) (between-subject design). The pooled data (n = 28) indicated that receiving problem solving therapy significantly reduced participants levels of depression and anxiety and increased quality of life levels from baseline to follow up (within-subject design), however, methodological limitations, such as the lack of a control group reduce the validity of this finding. The between-subject results suggest that there was no significant difference between those that received problem solving therapy and a waitlist control group between baseline and post-waitlist/post-therapy. The within-subject design suggests that problem solving therapy may be beneficial for younger stroke survivors when they are given some time to learn and implement the skills into their day to day life. However, additional research with a control group is required to investigate this further. This study provides limited evidence for the provision of support groups for younger stroke survivors post stroke, however, it remains unclear about what type of support this should be. Implications for Rehabilitation Problem solving therapy is no more effective for reducing post stroke distress than a wait-list control group. Problem solving therapy may be perceived as helpful and enjoyable by younger stroke survivors. Younger stroke survivors may use the skills learnt from problem solving therapy to solve problems in their day to day lives. Younger stroke survivors may benefit from age appropriate psychological support; however, future research is needed to determine what type of support this should be.

Objective: To investigate the protective effect of Saccharomyces boulardii against intestinal mucosal barrier injury in rats with nonalcoholic fatty liver disease (NAFLD). Methods: A total of 36 healthy male Sprague-Dawley rats with a mean body weight of 180±20 g were randomly divided into control group, model group, and treatment group, with 12 rats in each group, after adaptive feeding for 1 week. The rats in the control group were given basic feed, and those in the model group and treatment group were given high-fat feed. After 12 weeks of feeding, the treatment group was given Saccharomyces boulardii (75×10 8 CFU/kg/d) by gavage, and those in the control group and model group were given isotonic saline by gavage. At the 20th week, blood samples were taken from the abdominal aorta to measure the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), intestinal fatty acid binding protein (IFABP), tumor necrosis factor-α (TNF-α), and endotoxins. The liver pathological changes, intestinal histopathological changes, and expression of occludin in the intestinal mucosa were observed. Fecal samples were collected to measure the changes in Escherichia coli and Bacteroides. A one-way analysis of variance and the SNK test were used for comparison between multiple groups, and the rank sum test was used as the non-parametric test. Results: Compared with the control group, the model group had significantly higher body weight, liver mass, and liver index ( P < 0.05), and compared with the model group, the treatment group had significant reductions in body weight, liver mass, and liver index ( P < 0.05). The model group had significant increases in TG, ALT, and AST compared with the control group ( P < 0.05), the treatment group had a significant reduction in AST compared with the model group ( P < 0.05), and the treatment group had slight reductions in TG and ALT compared with the model group ( P > 0.05). Compared with the control group, the model group had significant increases in the levels of endotoxin, TNF-α, and IFABP ( P < 0.05), and the treatment group had significant reductions in the levels of endotoxin, TNF-α, and IFABP ( P < 0.05). Liver tissue staining showed that the model group had significantly increased hepatocyte steatosis compared with the control group ( P < 0.05), and that the treatment group had significantly reduced hepatocyte steatosis compared with the model group ( P < 0.05). The intestinal villi in the control group had ordered arrangement and a complete structure; in the model group, the intestinal villi were shortened with local shedding and a lack of ordered arrangement; compared with the model group, the treatment group had mild edema and ordered arrangements of the intestinal villi. The model group had a significantly reduced level of occludin protein compared with the control group ( P < 0.05), and the treatment group had a slight increase compared with the model group. The model group had a significantly increased number of Escherichia coli and a significantly reduced number of Bacteroides compared with the control group ( P < 0.05), and the treatment group had a significantly reduced number of Escherichia coli and a significantly increased number of Bacteroides compared with the model group ( P < 0.05). Conclusion: High-fat diet can successfully induce NAFLD in rats, and intervention with Saccharomyces boulardii can reduce body weight and improve hepatocyte steatosis. Saccharomyces boulardii can reduce endotoxemia in NAFLD rats and thus alleviate inflammatory response. Saccharomyces boulardii can also adjust the proportion of Escherichia coli and Bacteroides in the intestine of NAFLD rats.

To test the working hypotheses that after a brief (10 min) intervention, (a) young adults can volitionally reduce fall-related wrist impact forces, and (b) no difference in impact force would exist between intervention and control groups at 3-weeks or 3-months follow-up. The wrist is the most commonly fractured site in the body at any age, most often as a result of impact with the ground while arresting a forward fall.Methods. Twenty-nine healthy young male volunteers participated. A 3-month intervention group (n=10) performed five standardized forward falls before and after a 10-min instructional intervention aimed at reducing wrist impact forces during the baseline visit. They, along with a 3-month control group (n=11) who did not receive the intervention, were remeasured in five trials at 3-weeks and 3-months follow-up, without intervening practice. A baseline control group (n=8) performed the five trials, then repeated them at the baseline visit without receiving the intervention. Unilateral body segment kinematics and bilateral hand-ground impact forces were measured and the hypotheses were tested using repeated measures analysis of variance. At the baseline visit, a significant group-by-trial-block interaction was found (P=0.02): the 3-month intervention group reduced their average maximum impact forces by 18% from initial values (P=0.002); the baseline control group did not do so (0.5% increase, P=0.91). The 3-month intervention (20 falls) and control (15 falls) groups did not differ at the 3-month follow-up (P=0.62); however, when the groups were combined their maximum impact force had decreased significantly (8.9%, P=0.04) over that time. Healthy young males learned in 10 min to significantly reduce wrist impact forces in forward falls, but retention was poor at 3-weeks follow-up. Irrespective of group, however, after the 5 falls at 3-weeks subjects had taught themselves to reduce their impact forces at the 3-months follow-up. A brief educational intervention can significantly reduce forward fall-related impact forces in the short term. However, with or without the brief intervention, the experience of performing between 5-10 forward falls 3 weeks apart apparently resulted in decreased impact forces over the next 2 months, thereby reducing the risk of injury in these forward falls.

To evaluate the effects of fulvestrant and micronized progesterone on post-operative adhesion formation and ovarian reserve in a rat uterine horn adhesion. In this prospective randomized controlled trial, 32 female Wistar albino rats were randomly divided into four groups including control group (Group 1), the control adhesion group (Group 2), 1 mg/kg daily intramuscular fulvestrant received group (Group 3) and 1 mg/kg daily oral micronized progesterone received group (Group 4). The extent and severity of adhesions were scored and samples were taken from adhesion areas to investigate the grades of adhesions according to the immunohistochemical scoring system. Ovarian reserves were measured with anti-Müllerian hormone (AMH) and histological ovarian follicles count. The extent, severity and total adhesion scores were reduced in all treatment groups compared to control adhesion group (Group 2). Similarly, immunohistochemical adhesion scores were lower in the treatment groups. AMH and follicle count were significantly found lower in adhesion groups compared with control group. However, treatment groups were found to have higher ovarian reserve compared to control adhesion group (Group 2). Fulvestrant and micronized progesterone were found to reduce post-operative adhesion formations and have decreased detrimental effects of adhesion formation on ovarian reserve.

The elemental diet (ED) Elental® reportedly reduces adverse reactions to chemotherapy in digestive system cancer patients; however, the mechanism is unclear. Therefore, we verified the protective effect of ED against gastrointestinal disorders induced by the antineoplastic drug 5-fluorouracil (5-FU). After 5 days of tail vein injections of 40 mg/kg/day 5-FU in female BALB/c mice, the mice were given oral ED (ED group) or dextrin with the same number of calories (control group). We measured the weight of salivary glands and the PAS-positive area of colonic mucosa and verified the antitumor effect in tumor-bearing mice given 5-FU and ED. Although body weight decreased after 5-FU treatment, ED group mice weighed more than control group mice. Additionally, although control mice developed diarrhea after 5-FU treatment, the ED group showed only loose stools. The control group saliva volume was approximately one sixth of the vehicle group volume after 5-FU treatment; this was improved to approximately half in the ED group. The area ratio of PAS-positive cells in the colonic mucosa was reduced by 5-FU treatment, with the ratio being higher in the ED group than that in the control group. Similar tumor growth suppression was observed in the 5-FU and ED groups. ED alleviated adverse reactions to 5-FU without affecting antitumor activity. Protection against 5-FU-induced weight loss was potentially due to both improved nutritional support with combined ingredients and prevention of diarrhea that is associated with reduced colonic goblet cells and decreased saliva production from reduced salivary gland contraction.

AIM: To assess the efficacy and safety of Saccharomyces boulardii (S. boulardii) in acute watery diarrhoea and its role in reducing the frequency of episodes of diarrhoea in subsequent two months. METHODS: Children from 2 mo to 12 years of age, with acute diarrhoea were selected according to inclusion criteria and randomised in S. boulardii group (treated with ORS, nutritional support and S. boulardii, 250 mg bid) and in control group (treated with ORS and nutritional support only). Active treatment phase was 5 d and each child was followed for two months afterwards. Frequency and consistency of stools as well as safety of drug was assessed on every visit. A comparison of two groups was done in terms of number of diarrhoeal episode in subsequent two months. RESULTS: There were fifty patients in each group. Baseline characteristics such as mean age and the average frequency of stools were comparable in S. boulardii and control group at the time of inclusion in the trial. By d 3 it reduced to 2.7 and 4.2 stools per d respectively and by d 6 it reduced to 1.6 (S. boulardii Group) and 3.3 (control group). The duration of diarrhoea was 3.6 d in S. boulardii group whereas it was 4.8 d in control group (P = 0.001). In the following two months, S. boulardii group had a significantly lower frequency of 0.54 episodes as compared to 1.08 episodes in control group. The drug was well accepted and tolerated. There were no reports of the side effects during treatment period. CONCLUSION: S. boulardii significantly reduces the frequency and duration of acute diarrhoea. The consistency of stool also improves. The drug is well-tolerated. PMID:16874872

Postpartum depression is one of the prevalent disorders among new mothers. The present research aimed to examine the effectiveness of mindfulness training on reducing the symptoms of postpartum depression. The present quasi-experimental research was conducted on 410 new mothers in Shahid Chamran Hospital, Tehran in 2014. Using the Beck Depression Inventory (BDI), Structured Clinical Interview and Psychological Clinical Diagnosis, 67 mothers were selected and then randomly divided into experimental and control groups, each of which with 32 applicants. Afterwards, the experimental group received mindfulness training for 8 sessions, each lasting for two hours while the control group received no training. The data were analyzed through descriptive statistics and Analysis of Covariance (ANCOVA) in SPSS, version 20. Results showed that based on Beck Inventory, the scores for the experimental group in post-test were significant (p<0.001), compared to those for the control group. Also, it was revealed that pre- and posttest mean scores for postpartum depression in the control group were 25.81 and 25.12 respectively while the scores for the experimental group were 24.75 and 18.5 respectively. Since the posttest mean score in the experimental group was lower than that in the pretest, it can be said that the treatment, i.e., mindfulness training, was effective in reducing depression symptoms in mothers. Findings proved that mindfulness training was effective in reducing the symptoms of postpartum depression in new mothers.

When administered perioperatively, systemic dexamethasone will reduce the hearing loss associated with cochlear implantation (CI) performed via the round window approach. The benefits of electroacoustic stimulation have led to interest in pharmacological interventions to preserve hearing after CI. Thirty guinea pigs were randomly divided into three experimental groups: a control group; a 3-day infusion group; and a 7-day infusion group. Dexamethasone was delivered via a mini-osmotic pump for either 3 or 7 days after CI via the round window. Pure tone-evoked auditory brainstem response (ABR) thresholds were monitored for a period of 12 weeks after CI. The cochleae were then collected for histology. At 4 and 12 weeks after CI, ABR threshold shifts were significantly reduced in both 7-day and 3-day infusion groups compared with the control group. Furthermore, the 7-day infusion group has significantly reduced ABR threshold shifts compared with the 3-day infusion group. The total tissue response, including fibrosis and ossification, was significantly reduced in the 7-day infusion group compared with the control group. On multiple regression the extent of fibrosis predicted hearing loss across most frequencies, while hair cell counts predicted ABR thresholds at 32 kHz. Hearing protection after systemic administration of steroids is more effective when continued for at least a week after CI. Similarly, this treatment approach was more effective in reducing the fibrosis that encapsulates the CI electrode. Reduced fibrosis seemed to be the most likely explanation for the hearing protection.

The present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. Using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected. Among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. Of all the pre-school children of these 3 kindergartens, 40 children who could have behavioral disorder, according to their teachers and parents, were carefully tested. Of them, 16 children who showed severe symptoms of oppositional defiant disorder, were selected via the results obtained from the child symptom inventory questionnaire (CSI-4), teacher's form, and a researcher-made self-control checklist, Then, the subjects were randomly divided into one control and one experimental group. This research is quasi-experimental, and is conducted using pre-test, post-test, and control group. Values of the calculated F for oppositional defiant disorder in control group and experimental group was meaningful after fixing the effect of pre-test (P<0/001). Therefore, a meaningful difference existed between the means of post-test scores of disobedience disorder in the experimental and control groups through the fixed effect of the pre-test effect. Comparison of adjusted means of the 2 groups showed that the mean of attention-deficit hyperactivity disorder (ADHD) in experimental group was lower than control group. Therefore, applying play therapy reduced severity of ADHD in those children in experimental group compared to those in control group who did not receive such instructions. Results of this research demonstrates that children's disobedience can be reduced by play therapy.

Mycoprotein is a food produced by continuous fermentation of Fusarium graminearum (Schwabe). A previous metabolic study showed that mycoprotein decreased total and low-density-lipoprotein (LDL) cholesterol and increased high-density-lipoprotein (HDL) cholesterol. This study was undertaken to determine the effects of mycoprotein under free-living conditions. Two groups of subjects with slightly raised cholesterol concentrations participated in the 8-wk study. The experimental group was fed cookies containing mycoprotein and the control group was fed a nutrient-balanced cookie without mycoprotein. After 8 wk of treatment total cholesterol was reduced by 0.46 mmol/L in the control group and 0.95 mmol/L in the mycoprotein group, and LDL was reduced by 0.34 mmol/L in the control group and 0.84 mmol/L in the mycoprotein group. All analysis of variance differences were statistically significant. This study confirms the metabolic-study results and we are now relatively confident that mycoprotein exerts a beneficial effect on blood lipids.

Purpose Pivoting neuromuscular control and proprioceptive acuity may play an important role in ACL injuries. The goal of this study was to investigate whether pivoting neuromuscular training on an offaxis elliptical trainer (POINT) could improve pivoting neuromuscular control, proprioceptive acuity, and functional performance. Methods Among 41 subjects, 21 subjects participated in 18 sessions of POINT (3 sessions/week for 6 weeks), and 20 subjects served as controls who did their regular workout. Both groups received pre-, mid-, and post-intervention evaluations. Propensity score analysis with multivariable regression adjustment was used to investigate the effect of training on pivoting neuromuscular control (pivoting instability, leg pivoting stiffness, maximum internal and external pivoting angles), proprioceptive acuity, and functional performance in both groups. Results Compared to the control group, the training group significantly improved pivoting neuromuscular control as reduced pivoting instability, reduced maximum internal and external pivoting angles, increased leg pivoting stiffness, and decreased entropy of time to peak EMG in the gluteus maximus and lateral gastrocnemius under pivoting perturbations. Furthermore, the training group enhanced weight-bearing proprioceptive acuity and improved the single leg hop distance. Conclusion Improvement of pivoting neuromuscular control in functional weight-bearing activities and task performances following POINT may help develop lower limb injury prevention and rehabilitation methods to reduce ACL and other musculoskeletal injuries associated with pivoting sports.

Comprehensive diabetes treatment has been shown to reduce quality of life in diabetic patients. However, there is evidence to suggest that group singing can have positive effects on quality of life in various clinical settings. In this randomized controlled pilot study, the effect of singing as a therapy to reduce stress and improve quality of life was investigated in insulin-dependent diabetic patients, undergoing a lifestyle intervention program. Patients from the singing group felt less discontented following treatment. This effect, however, was lost after 3 months. No effect on serum cortisol and plasma adrenocorticotropic hormone (ACTH) levels could be seen when comparing the singing group with the control group, although reduced levels of ACTH and cortisol 3 days after treatment could be found and were still present after 3 months within the group of patients who undertook singing as a therapy. Singing led to an increase in bodyweight, which interestingly had no effect on glucose control or methylglyoxal levels. Therefore, singing during a lifestyle intervention program for insulin-dependent diabetic patients had a short lasting and weak effect on patients' mood without affecting glucose control, but no significant effect on stress related hormones. © Georg Thieme Verlag KG Stuttgart · New York.

This study evaluated the feasibility of a home-based intervention to reduce sugar sweetened beverage intake and television viewing among children. Lower-income parents of overweight children ages 5-12 yrs (n=40) were randomized to a home environment intervention to reduce television viewing with locking devices and displace availability of sugar sweetened beverages with home delivery of non-caloric beverages (n=25), or to a no-intervention control group (n=15) for six months. Data were collected at baseline and six months. After six months, television viewing hours per day was significantly lower in the intervention group compared with the control group (1.7 [se=.02] vs. 2.6 [se = .25] hrs/day, respectively, p < .01). Sugar sweetened beverage intake was marginally significantly lower among intervention group compared to control group children (0.21 [se=.09] vs. 0.45 [se=.10], respectively, p < .09). BMI z-score was not significantly lower among intervention compared to control children. Among a lower-income sample of children, a home-based intervention reduced television viewing, but not sugar-sweetened beverage intake or BMI z-score. PMID:26317968

This study observed its effectiveness and safety of the treatment of the disease and its influence on the serum prostaglandin F2α, endothefin, pulsatility index and resistant index of uterine artery blood, to explore the possible mechanism of effect of Dingkun Dan in the treatment of dysmenorrhea and provide scientific basis for clinical application. The 75 patients with dysmenorrhea of cold stagnation and blood stasis who met the inclusion criteria, were divided into treatment group (n=37) and control group (n=38) by using random number remainder grouping method. In the treatment group patients were treated with Dingkun Dan, the other group were given Fuke Zaizao Jiaonang. Two groups have same time to take the medicine, three days prior to the menstruation for ten days. Medication for three menstrual cycles was seen as a course of treatment. To observe and compare the two groups of patients before and after treatment VAS score, syndrome integral, serum levels of prostaglandin F2α and endothelin, pulsation index and resistance index of uterine artery blood flow and related safety index changes. Finally makes statistical analysis. It has been identified that, Treatment group and control group can reduce pain symptom of dysmenorrhea patients and improve the syndromes scores, compare with control group, effect of the treatment group is more significant(P<0.01). VAS pain curative effect: the treatment group and control group total effective rate respectively were, 97.22%, 69.44%, markedly effective rate were 83.33%, 30.56%, comparison between two groups, treatment group is better than that of control group(P＜0.01). Syndromes curative effect: the treatment group and control group total effective rate respectively were 97.22%, 94.44%, markedly effective rate was 66.67%, 2.78%, respectively. The comparison between two groups, the total effective rate has no obvious difference, but markedly effective rate of treatment group is better than that of control group(P＜0.01). The treatment group can significantly reduce the patients' serum level of prostaglandin F2α(P<0.01), but no obvious difference was found in the control group before and after treatment. Both groups can significantly reduce the serum level of endothelin(P<0.01), comparison between two groups, the treatment group is more significant(P<0.01).Both treatment group and control group were significantly lower left and right pulsation index and resistance index of uterus artery blood flow(P<0.01). Between groups to compare the effect, the treatment group is more significant(P<0.01). Both treatment group and control group in the security check before and after treatment found no significant anomalies. Dingkun Dan in treating dysmenorrhea with cold stagnation and blood stasis syndrome seems to have remarkable clinical curative effect and safety, which may be achieved by significantly reducing the serum level of prostaglandin F2αand endothefin of the patients, and reducing the pulsation index and resistance index of uterine artery blood flow of the patients, to improve uterine artery condition of blood, and correcting local tissue ischemia to relieve pain.

Previous research studies have indicated that biofeedback treatment and relaxation techniques are effective in reducing psychological and physical symptoms (Hammond, 2005; Manzoni, G. M., Pagnini, F., Castelnuovo, G., & Molinari, E., 2008). However, dearth of studies has compared heart rate variability (HRV) biofeedback treatment and relaxation training to reduce trait anxiety. The objective of this study was to determine the effect of HRV biofeedback treatment and relaxation training in reducing trait anxiety compared to control group without any treatment using students in a science and engineering university of South Korea. For the present study, a total of 15 graduate students with moderate level of trait anxiety were recruited for 4 individual sessions every two weeks. They were randomly assigned into three groups: biofeedback treatment (n = 5), relaxation training (n = 5), and no treatment control group (n = 5). Our results revealed significant difference in change score of trait anxiety between the HRV biofeedback treatment and the no treatment control group. However, no significant difference was found between the relaxation training group and the no treatment control group. In addition, there was no significant difference between the HRV biofeedback treatment and the relaxation training. Results of the present study indicate that there is potential benefit in utilizing HRV biofeedback treatment for stress management programs and/or anxiety reduction treatment.

Purpose. Aromatherapy massage is an alternative treatment in reducing the pain of the cancer patients. This study was to investigate whether aromatherapy massage could improve the pain of the cancer patients. Methods. We searched PubMed and Cochrane Library for relevant randomized controlled trials without language limitations between 1 January 1990 and 31 July 2015 with a priori defined inclusion and exclusion criteria. The search terms included aromatherapy, essential oil, pain, ache, cancer, tumor, and carcinoma. There were 7 studies which met the selection criteria and 3 studies were eventually included among 63 eligible publications. Results. This meta-analysis included three randomized controlled trials with a total of 278 participants (135 participants in the massage with essential oil group and 143 participants in the control (usual care) group). Compared with the control group, the massage with essential oil group had nonsignificant effect on reducing the pain (standardized mean difference = 0.01; 95% CI [−0.23,0.24]). Conclusion. Aromatherapy massage does not appear to reduce pain of the cancer patients. Further rigorous studies should be conducted with more objective measures. PMID:26884799

A recent study of supermarket bakery workers in South Africa demonstrated that 25% of workers were sensitised to flour allergens and 13% had baker's asthma. Evidence on exposure reduction strategies using specifically designed interventions aimed at reducing the risk of baker's asthma is scarce. The aim of this study was to evaluate the effectiveness of different control measures to reduce airborne flour dust exposure using a randomised design. A group-randomised study design was used to assign 30 bakeries of a large supermarket chain store to two intervention groups and a control group, of which 15 bakeries were studied. Full-shift environmental personal samples were used to characterise exposure to flour dust and wheat and rye allergens levels pre-intervention (n=176) and post-intervention (n=208). The overall intervention effect revealed a 50% decrease in mean flour dust, wheat and rye allergen exposure. The reduction in exposure was highest for managers (67%) and bakers (47%), and lowest for counterhands (23%). For bakers, the greatest reduction in flour dust was associated with control measures such as the use of the mixer lid (67%), divider oil (63%) or focused training (54%). However, the greatest reduction (80%) was observed when using a combination of all control measures. A specially designed intervention strategy reduced both flour dust and allergen levels. Best results were observed when combining both engineering controls and training. Further studies will investigate the long-term health impact of these interventions on reducing the disease burden among this group of bakers. Published by the BMJ Publishing Group Limited.

2012-02-01

The purpose of this research was to evaluate the effects of a cognitive training and cell phone intervention on the recidivism of 70 juvenile offenders. Median days to rearrest were 106 for the control group, 191 for the class-only group, and 278 for the class plus cell phone group. Using rearrest as the survival criterion, the survival ratios of the class-only and class plus cell phone groups were 2.64 and 2.94 times longer than the control group, respectively. After controlling for gender, prior arrests, and risk score, the Poisson regression indicated that the class-only and class plus cell phone groups were 51% lower in total arrests than the control group. These results suggest that cognitive training supplemented with a cell phone coach is an effective and cost-efficient intervention for reducing recidivism.

Complete UCLP patients who were treated at our centre were divided into two groups. The study group underwent PNAM and was further subdivided into three subgroups (PNAM initiated within 1 month, between 1 and 6 months, and between 6 and 12 months of age in subgroup I, II, and III, respectively). The control group did not undergo PNAM and was further subdivided into three subgroups. Patients were evaluated at T1 (first visit), T2 (before cheiloplasty), and T3 (at 6 years). Between T1and T2, the intersegment distance (ISD) reduced significantly in the study group but increased in the control group, whereas the intercanine width (ICW) in both the study and control groups did not show significant change. Between T2 and T3, ISD and ICW were reduced significantly in the control group due to arch collapse, whereas in the study group, ISD reduced slightly with ICW remaining almost similar to noncleft norms. We conclude that reduced ISD following PNAM improves arch symmetry and stability, and thus may prevent arch collapse in the long term.

The consequences of falls are devastating for patients with stroke. Balance problems and fear of falling are two major challenges, and recent systematic reviews have revealed that habitual physical exercise training alone cannot reduce the occurrence of falls in stroke survivors. However, recent trials with community-dwelling healthy older adults yielded the promising result that interventions with a cognitive behavioral therapy (CBT) component can simultaneously promote balance and reduce the fear of falling. Therefore, the aim of the proposed clinical trial is to evaluate the effectiveness of a combination of CBT and task-oriented balance training (TOBT) in promoting subjective balance confidence, and thereby reducing fear-avoidance behavior, improving balance ability, reducing fall risk, and promoting independent living, community reintegration, and health-related quality of life of patients with stroke. The study will constitute a placebo-controlled single-blind parallel-group randomized controlled trial in which patients are assessed immediately, at 3 months, and at 12 months. The selected participants will be randomly allocated into one of two parallel groups (the experimental group and the control group) with a 1:1 ratio. Both groups will receive 45 min of TOBT twice per week for 8 weeks. In addition, the experimental group will receive a 45-min CBT-based group intervention, and the control group will receive 45 min of general health education (GHE) twice per week for 8 weeks. The primary outcome measure is subjective balance confidence. The secondary outcome measures are fear-avoidance behavior, balance ability, fall risk, level of activities of daily living, community reintegration, and health-related quality of life. The proposed clinical trial will compare the effectiveness of CBT combined with TOBT and GHE combined with TOBT in promoting subjective balance confidence among chronic stroke patients. We hope our results will provide evidence of a safe, cost-effective, and readily transferrable therapeutic approach to clinical practice that reduces fear-avoidance behavior, improves balance ability, reduces fall risk, promotes independence and community reintegration, and enhances health-related quality of life.

Epidemiologic studies indicate that indoor air pollution is correlated with morbidity caused by allergic diseases. We evaluated the effectiveness of reducing the levels of indoor fine particulate matter <2.5 micrometer diameter (PM 2.5 ) in Fresno, California using air purifiers on health outcomes in children with asthma and/or allergic rhinitis. The active group (with air purifiers) and the control group consisted of eight houses each. Air purifiers were installed in the living rooms and bedrooms of the subjects in the active group during the entire 12-week study duration. Childhood asthma control test, peak flow rate monitoring, and nasal symptom scores were evaluated at weeks 0, 6, and 12. At 12 weeks, the active group showed a trend toward an improvement of childhood asthma control test scores and mean evening peak flow rates, whereas the control group showed deterioration in the same measures. Total and daytime nasal symptoms scores significantly reduced in the active group (p = 0.001 and p = 0.011, respectively). The average indoor PM 2.5 concentrations reduced by 43% (7.42 to 4.28 μg/m 3 ) in the active group (p = 0.001). Intervention with air purifiers reduces indoor PM 2.5 levels with significant improvements in nasal symptoms in children with allergic rhinitis in Fresno.

The aim of this study was to develop and measure the effect of a movie-based-nursing intervention program designed to enhance motivation for rehabilitation and reduce depression levels in stroke patients. The study used a quasi-experimental, nonequivalent control group and a pretest-posttest design. The 60 research subjects were assigned to the experimental (n=30) or control group (n=30). The moviebased nursing intervention program was provided for the experimental group during 60-minute sessions held once per week for 10 weeks. The program consisted of patient education to strengthen motivation for rehabilitation and reduce depression, watching movies to identify role models, and group discussion to facilitate therapeutic interaction. After 10 weeks of participation in the movie-based nursing intervention program, the experimental group's rehabilitation motivation score was significantly higher, F=1161.54 (within groups df=49, between groups df=1), p<.001, relative to that observed in the control group. In addition, the experimental group's depression score was significantly lower relative to that observed in the control group, F=258.97 (within groups df=49, between groups df=1), p<.001. The movie-based nursing intervention program could be used for stroke patients experiencing psychological difficulties including reduced motivation for rehabilitation and increased depression during the rehabilitation process. © 2017 Korean Society of Nursing Science

Background Falls in older people are a major public health issue, but the underlying causes are complex. We sought to evaluate the effectiveness of preventive home visits as a multifactorial, individualized strategy to reduce falls in community-dwelling older people. Methods Data were derived from a prospective randomized controlled trial with follow-up examination after 18 months. Two hundred and thirty participants (≥80 years of age) with functional impairment were randomized to intervention and control groups. The intervention group received up to three preventive home visits including risk assessment, home counseling intervention, and a booster session. The control group received no preventive home visits. Structured interviews at baseline and follow-up provided information concerning falls in both study groups. Random-effects Poisson regression evaluated the effect of preventive home visits on the number of falls controlling for covariates. Results Random-effects Poisson regression showed a significant increase in the number of falls between baseline and follow-up in the control group (incidence rate ratio 1.96) and a significant decrease in the intervention group (incidence rate ratio 0.63) controlling for age, sex, family status, level of care, and impairment in activities of daily living. Conclusion Our results indicate that a preventive home visiting program can be effective in reducing falls in community-dwelling older people. PMID:23788832

We investigated factors hypothesized to moderate the effects of cognitive behavioral group-based (CB group) and bibliotherapy depression prevention programs. Using data from two trials (N = 631) wherein adolescents (M age = 15.5, 62% female, 61% Caucasian) with depressive symptoms were randomized into CB group, CB bibliotherapy, or an educational brochure control condition, we evaluated the moderating effects of individual, demographic, and environmental factors on depressive symptom reductions and major depressive disorder (MDD) onset over 2-year follow-up. CB group and bibliotherapy participants had lower depressive symptoms than controls at posttest but these effects did not persist. No MDD prevention effects were present in the merged data. Relative to controls, elevated depressive symptoms and motivation to reduce depression amplified posttest depressive symptom reduction for CB group, and elevated baseline symptoms amplified posttest symptom reduction effects of CB bibliotherapy. Conversely, elevated substance use mitigated the effectiveness of CB group relative to controls on MDD onset over follow-up. Findings suggest that both CB prevention programs are more beneficial for youth with at least moderate depressive symptoms, and that CB group is more effective for youth motivated to reduce their symptoms. Results also imply that substance use reduces the effectiveness of CB group-based depression prevention. PMID:26480199

The purpose of this study was to determine how reduced plantar cutaneous sensation influences static postural control in individuals with and without CAI. A case-control study design. Twenty-six individuals with self-reported CAI and 26 matched healthy controls participated in this study. The plantar aspect of the participants' foot was then submersed in ice water (0°C) for 10min to reduce plantar sensation. Before and after the cooling procedure, plantar cutaneous sensation thresholds and single leg balance with eyes open and closed were assessed. Significantly, higher scores were observed in both groups after ice water submersion (p<0.001) indicating a significant reduction in the plantar cutaneous sensitivity after the cooling procedure. In single limb balance with eyes open, there were significant intervention main effects for the TTB ML mean (p<0.001), TTB AP mean (p=0.035) and TTB ML SD (p=0.021); indicating postural control improvement in both groups post-cooling. In single limb balance with eyes closed, Group×Intervention interactions were observed for the TTB AP mean (p=0.003) and TTB AP SD (p=0.017); indicating postural control deficits in CAI group post-cooling, but no changes in the control group. The main finding of this study was that reduced plantar cutaneous sensation induced by an ice submersion procedure caused eyes closed postural control impairments in those with CAI but not healthy controls. The present investigation demonstrated that the ability to dynamically reweight among sensory inputs to maintain postural stability appears to be diminished in CAI patients compared to healthy controls.

Aflatoxin B1 (AFB1 ) is considered as the most toxic food contaminant, and microorganisms, especially bacteria, have been studied for their potential to reduce the bioavailability of mycotoxins including aflatoxins. Therefore, this research investigated the efficacy of oral administration of Lactobacillus casei Shirota (LcS) in aflatoxin-induced rats. Sprague Dawley rats were divided into three groups of untreated control, the group induced with AFB1 only, and the group given probiotic in addition to AFB1. In the group induced with AFB1 only, food intake and body weight were reduced significantly. The liver and kidney enzymes were significantly enhanced in both groups induced with AFB1 , but they were lower in the group given LcS. AFB1 was detected from all serum samples except for untreated control group's samples. Blood serum level of AFB1 in the group induced with AFB1 only was significantly higher than the group which received probiotic as a treatment (P < 0·05), and there was no significant difference between the control group and the group treated with probiotic. LcS supplementation could improve the adverse effect of AFB1 induction on rats' body weight, plasma biochemical parameters and also could reduce the level of AFB1 in blood serum. This study's outcomes contribute to better understanding of the potential of probiotic to reduce the bioavailability ofAFB1 . Moreover, it can open an opportunity for future investigations to study the efficacy of oral supplementation of probiotic LcS in reducing aflatoxin level in human. © 2013 The Society for Applied Microbiology.

Anti-fibrinolytic agents are used to reduce obstetric blood loss as the fibrinolytic system is known to get activated after placental delivery. To evaluate the efficacy of parenteral tranexamic acid in reducing blood loss during normal labour and to compare it with the amount of blood loss in patients who received placebo in the third stage of labour. Patients with spontaneous labour or planned for induction of labour and fulfilling the inclusion criteria were recruited for the study. In each patient, the pre-delivery pulse rate, blood pressure, Hb gm% and PCV% were noted. Labour was monitored carefully using a partogram. The study group received Inj. Oxytocin and Inj. Tranexamic acid. The control group received Inj. Oxytocin and Placebo injection. Immediately after delivery of the baby, when all the liquor was drained, the patient was placed over a blood drape-a disposable conical, graduated plastic collection bag. The amount of blood collected in the blood drape was measured. Then the patient was given pre-weighed pads, which were weighed 2 h post-partum. The blood loss was measured by measuring the blood collected in the drape and by weighing the swabs before and after delivery. The total number of patients studied was 100-equally distributed in both the groups. The age group of the patients and BMI were comparable. There was a significant increase in the pulse rate and decrease in blood pressure in the control group as compared with the study group. The post-delivery haemoglobin and haematocrit were significantly reduced in the control group as compared to the study group. The mean blood loss at the end of 2 h was 105 ml in the study group and 252 ml in the control group. There was a significant increase in the usage of uterotonics and also in the need for blood transfusion in the control group; 12 % of the patients in the control group had to stay for more than 3 days compared to 2 % in the study group. Tranexamic acid injection, an antifibrinolytic agent when given prophylactically after the delivery of the baby, by intravenous route appears to reduce the blood loss and maternal morbidity during normal labour effectively.

The focus of the study was to examine leptin and other peripheral signals of energy balance, following hypergravity. The study was conducted in two experiments. In experiment 1 rats were centrifuged at either 1.5, 2, or remained at 1 G. During days 8 to 14 of experiment 1, mean body mass of the 1.5 and 2 G groups was significantly (p<0.05) lower than controls. No differences were found in food intake (g/day/100 g body mass). Epididymal fat in the 2 G group was 21% lower than controls and 14% lower than the 1.5 G group. Plasma leptin was reduced from controls in the 1.5 and 2 G groups by 45 and 63%, respectively. A significant correlation was found between G load and urinary catecholamines. In experiment 2, rats were centrifuged at either 1.25, 1.5, or remained at 1 G. During days 8 to 14, body mass and food intake were similar between the 1, 1.25, and 1.5 G groups. Epididymal fat was reduced from controls in the 1.25 (14%) and 1.5 (19%) G groups. Leptin was reduced from controls in the 1.25 (45%) and 1.5 (46%) G groups. No differences were found in urinary epinephrine. Urinary norepinephrine levels were significantly higher than controls in each centrifuge group. During hypergravity exposure, food intake is the result of a complex relationship between multiple pathways, which abates the importance of leptin as a primary signal.

Periarticular infiltration of local anesthetic, NSAIDs, and adrenaline have been reported to reduce postoperative pain, improve mobility, and reduce hospital stay for patients having THAs, but available studies have not determined whether local anesthetic infiltration alone achieves similar improvements. We therefore asked whether periarticular injection of a local anesthetic during THA reduced postoperative pain and opioid requirements and improved postoperative mobility. We randomized 96 patients to either treatment (n = 50) or control groups (n = 46). Before wound closure, the treatment group received local infiltration of 160 mL of levobupivacaine with adrenaline. The control group received no local infiltration. We assessed postoperative morphine consumption and pain during the 24 hours after surgery. Mobilization was assessed 24 hours postoperatively with supine-to-sit and sit-to-stand transfers, timed 10-m walk test, and timed stair ascent and descent. Patients and assessing physiotherapists were blind to study status. We observed no differences in postoperative morphine consumption, time to ascend and descend stairs, or ability to transfer between treatment and control groups. The treatment group reported more pain 7 to 12 hours postoperatively, but there were no differences in pain scores between groups at all other postoperative intervals. The treatment group showed increased postoperative walking speed greater than 6 m, but not greater than 10 m, compared with the control group. Periarticular infiltration of local anesthetic during THA did not reduce postoperative pain or length of hospital stay and did not improve early postoperative mobilization.

Objective The present research was conducted to study the effect of play therapy on reducing behavioral problems of children with oppositional defiant disorder. Method Using multistage cluster sampling, regions 6, 7, and 8 in Tehran were selected. Among kindergartens of these areas, 3 kindergartens which were supported by the welfare organization were randomly selected. Of all the pre-school children of these 3 kindergartens, 40 children who could have behavioral disorder, according to their teachers and parents, were carefully tested. Of them, 16 children who showed severe symptoms of oppositional defiant disorder, were selected via the results obtained from the child symptom inventory questionnaire (CSI-4), teacher's form, and a researcher-made self-control checklist, Then, the subjects were randomly divided into one control and one experimental group. This research is quasi-experimental, and is conducted using pre-test, post-test, and control group. Results Values of the calculated F for oppositional defiant disorder in control group and experimental group was meaningful after fixing the effect of pre-test (P<0/001). Therefore, a meaningful difference existed between the means of post-test scores of disobedience disorder in the experimental and control groups through the fixed effect of the pre-test effect. Comparison of adjusted means of the 2 groups showed that the mean of attention-deficit hyperactivity disorder (ADHD) in experimental group was lower than control group. Therefore, applying play therapy reduced severity of ADHD in those children in experimental group compared to those in control group who did not receive such instructions. Conclusion Results of this research demonstrates that children's disobedience can be reduced by play therapy. PMID:22952519

This randomized controlled trial investigated the effects of a 12 month whole body vibration training program on postural control in healthy older adults. Two hundred and twenty people were randomly assigned to a whole body vibration group (n=94), a fitness group (n=60) or a control group (n=66). The whole body vibration and fitness groups trained three times a week for 1 year. The vibration group performed exercises on a vibration platform and the fitness group performed cardiovascular, strength, balance and stretching exercises. Balance was measured using dynamic computerized posturography at baseline and after 6 and 12 months. Whole body vibration training was associated with reduced falls frequency on a moving platform when vision was disturbed and improvements in the response to toes down rotations at the ankle induced by the moving platform. The fitness group showed reduced falls frequency on the moving surface when vision was disturbed. Thus, whole body vibration training may improve some aspects of postural control in community dwelling older individuals.

The aim of this study was to investigate whether isometric neck extension exercise restores physiological cervical lordosis and reduces pain. Sixty-five patients with loss of cervical lordosis were randomly assigned to exercise (27 women, 7 men; mean age, 32.82 ± 8.83 yrs) and control (26 women, 5 men; mean age, 33.48 ± 9.67 yrs) groups. Both groups received nonsteroidal anti-inflammatory drugs for 10 days. The exercise group received additional therapy as a home exercise program, which consisted of isometric neck extension for 3 mos. Neck pain severity and cervical lordosis were measured at baseline and at 3 mos after baseline. Compared with baseline levels, cervical lordosis angle was significantly improved in the exercise group (P < 0.001) but not in the control group (P = 0.371) at the end of 3 mos. Moreover, the exercise group was significantly superior to the control group considering the number of patients in whom cervical lordosis angle returned to physiological conditions (85.2% vs. 22.5%; P < 0.001). At the end of 3 mos, pain intensity was significantly reduced in both groups compared with baseline levels (for all, P < 0.001). Nevertheless, considering the change from baseline to month 3, the reduction in pain was about twice in the exercise group compared with the control group (P < 0.001). Isometric neck extension exercise improves cervical lordosis and pain.

Group Music Intervention Reduces Aggression and Improves Self-esteem in Children with Highly Aggressive Behavior: A Pilot Controlled Trial

We investigated the effects of group music intervention on aggression and self-esteem in children with highly aggressive behavior. Forty-eight children were allocated to either a music intervention group or an untreated control group. The music intervention group received 50 min of music intervention twice weekly for 15 consecutive weeks. The outcome measures were Child Behavior Checklist Aggression Problems Scale (Parents), Child Aggression Assessment Inventory (Teachers) and Rosenberg Self-esteem Scale. After 15 weeks, the music intervention group showed significant reduction of aggression and improvement of self-esteem compared with the control group. All outcome measures were significantly lower in the music intervention group than prior to treatment, while there was no change in the control group. These findings suggest that music can reduce aggressive behavior and improve self-esteem in children with highly aggressive behavior. Music intervention is an easily accessible therapy for children and as such may be an effective intervention for aggressive behavior. Further more, objective and replicable measures are required from a randomized controlled trial with a larger sample size and active comparable control. PMID:18955314

There is a dearth of reports on possible additive blood pressure (BP)-reducing effect of aerobic exercise on antihypertensive drug in humans. This study investigated the additive BP-reducing effect of aerobic exercise on BP in individuals with uncontrolled hypertension. In this 12-week double-blind study, 120 new-diagnosed individuals with mild-to-moderate hypertension were randomized to receive coamilozide + 5/10 mg of amlodipine + aerobic dance or coamilozide + 5/10 mg of amlodipine alone. Forty-five and 43 participants in exercise and control groups, respectively, completed the 12-week intervention. Addition of aerobic exercise to antihypertensive drug therapy significantly reduced systolic BP (7.1 mm Hg [95% confidence interval: 5.0, 9.3]; P < .001) and diastolic BP (1.7 mm Hg [95% confidence interval: 0.4, 3.0]; P = .009) at 12 weeks. BP control rate differed significantly between exercise (53.9%) and control (35.3%) groups, P < .001. Postintervention, proportion of participants in exercise group who had their number of antihypertensive drug reduced to one (20.3%) differed from that in control group (11.1%); (χ(2) = 11.0; P = .001). Combination of aerobic dance and antihypertensive drugs reduces number of antihypertensive drugs needed to achieve BP control and enhances BP control in individuals with hypertension on two antihypertensive drugs.

Gaining experience on a cognitive task improves behavioral performance and is thought to enhance brain efficiency. Despite the body of literature already published on the effects of training on brain activation, less research has been carried out on visual search attention processes under well controlled conditions. Thirty-six healthy adults divided into trained and control groups completed a pre-post letter-based visual search task fMRI study in one day. Twelve letters were used as targets and ten as distractors. The trained group completed a training session (840 trials) with half the targets between scans. The effects of training were studied at the behavioral and brain levels by controlling for repetition effects using both between-subjects (trained vs. control groups) and within-subject (trained vs. untrained targets) controls. The trained participants reduced their response speed by 31% as a result of training, maintaining their accuracy scores, whereas the control group hardly changed. Neural results revealed that brain changes associated with visual search training were circumscribed to reduced activation in the posterior parietal cortex (PPC) when controlling for group, and they included inferior occipital areas when controlling for targets. The observed behavioral and brain changes are discussed in relation to automatic behavior development. The observed training-related decreases could be associated with increased neural efficiency in specific key regions for task performance. Copyright © 2016 Elsevier Inc. All rights reserved.

Self-control resources can be defined in terms of "energy." Repeated attempts to override desires and impulses can result in a state of reduced self-control energy termed "ego depletion" leading to a reduced capacity to regulate future self-control behaviors effectively. Regular practice or "training" on self-control tasks may improve an individual's capacity to overcome ego depletion effectively. The current research tested the effectiveness of training using a novel Internet-based smartphone application to improve self-control and reduce ego depletion. In two experiments, participants were randomly assigned to either an experimental group, which received a daily program of self-control training using a modified Stroop-task Internet-based application delivered via smartphone to participants over a 4-week period, or a no-training control group. Participants assigned to the experimental group performed significantly better on post-training laboratory self-control tasks relative to participants in the control group. Findings support the hypothesized training effect on self-control and highlight the effectiveness of a novel Internet-based application delivered by smartphone as a practical means to administer and monitor a self-control training program. The smartphone training application has considerable advantages over other means to train self-control adopted in previous studies in that it has increased ecological validity and enables effective monitoring of compliance with the training program.

The null hypothesis was that mandibular amplitude, velocity, and variability during gum chewing are not altered in subjects with temporomandibular joint (TMJ) internal derangements (ID). Thirty symptomatic subjects with confirmed ID consented to chew gum on their left and right sides while being tracked by an incisor-point jaw tracker. A gender and age matched control group (p > 0.67) volunteered to be likewise recorded. Student's t-test compared the ID group's mean values to the control group. The control group opened wider (p < 0.05) and chewed faster (p < 0.05) than the ID group. The mean cycle time of the ID group (0.929 s) was longer than the control group (0.751 s; p < 0.05) and more variable (p < 0.05). The ID group exhibited reduced amplitude and velocity but increased variability during chewing. The null hypothesis was rejected. Further study of adaptation to ID by patients should be pursued.

The psychoprophylactic programs (PPP) have been widely used in women to face the fear-tension-pain cycle, reducing anxiety and pain during labour. The aim was to demonstrate if a PPP reduces the caesarean rate. 300 low risk pregnant women were included; 100 in the PPP group and 200 in the control group. The PPP participants attended theory and practical sessions; they visited labor, delivery, recovery and hospitalization areas. Chi-square, Student's t test and odds ratio were applied. Pregnancy ended by caesarean section in 35/100 of PPP group and in 99/200 (49.5%) in control group (p < 0.02, OR = 1.8, IC = 1.1-2.9). Maternal complications occurred in 13/100 in the PPP group, and 42/200 (21%) in control group (p = 0.09, RM = 0.56). The newborn (NB) complications were observed in 9/100 in PPP and 46/200 (23%) in control group (p < 0.02, OR = 0.33). In the PPP group, 70% assisted to three or more sessions. Hospital stance in control group, accumulated 17 days more in mothers and 171 days more in NB than in the PPP group. In PPP group observed a caesarean rate reduction with fewer maternal and perinatal complications.

As epilepsy affects approximately one percent of the world population, electrical stimulation of the brain has recently shown potential for additive seizure control therapy. In this study we applied noninvasive transcranial focal stimulation (TFS) via concentric ring electrodes on the scalp of rats after inducing seizures with pentylenetetrazole (PTZ) to assess the effect of TFS on the electrographic activity. Grand average power spectral densities were calculated to compare different stages of seizure development. They showed a significant difference between the TFS treated group and the control group. In case of the TFS treated group, after TFS, the power spectral density was reduced further towards a pre-seizure "baseline" than it was for the control group. The difference is the most drastic in delta, theta and alpha frequency bands. Application of general likelihood ratio test showed that TFS significantly (p<0.001) reduced the power of electrographic seizure activity in the TFS treated group compared to controls in more than 86% of the cases. These results suggest that TFS may have an anticonvulsant effect.

The aim of this study was to test a 180-minute group HIV risk-reduction counseling intervention trial with men undergoing traditional circumcision in South Africa to reduce behavioral disinhibition (false security) as a result of the procedure. A cluster randomized controlled trial design was employed using a sample of 160 men, 80 in the experimental group and 80 in the control group. Comparisons between baseline and 3-month follow-up assessments on key behavioral outcomes were completed. We found that behavioral intentions, risk-reduction skills, and male role norms did not change in the experimental compared to the control condition. However, HIV-related stigma beliefs were significantly reduced in both conditions over time. These findings show that one small-group HIV risk-reduction intervention did not reduce sexual risk behaviors in recently traditionally circumcised men at high risk for behavioral disinhibition.

Tranexamic acid has been shown to be effective in reducing blood loss after total hip replacement. The purpose of this study was to prospectively assess the effectiveness of topical TXA use to reduce blood loss after primary total hip replacement and to compare these outcomes with those of a matched control group from a similar cohort that did not have received tranexamic acid. This is a prospective matched control study to assess the effect of a 2 g topical tranexamic acid in 50 mL physiological saline solution in total hip replacement. Primary outcomes were hemoglobin and hematocrit drop, and total blood loss. Secondary outcomes were transfusion rates, length of hospital stay, deep vein thrombosis, and pulmonary embolism events. We could match 100 patients to a control group. There were no statistical significantly differences between the two groups. The hemoglobin and hematocrit postoperative values were significantly higher in topical tranexamic acid group than in control group (P < 0.001). The mean total blood loss was 769 in topical tranexamic acid group and 1163 in control group with significant differences (P = 0.001), which meant 34% reduction in total blood loss. Length of stay was lower in topical tranexamic acid group. The risk of deep vein thrombosis and pulmonary events did not increase. A single dose of 2 g tranexamic acid in 50 mL physiological saline solution topical administration was effective and safe in reducing bleeding in patients undergoing unilateral primary non-cemented total hip replacement compared to a matched control group.

The prevalence of depression is increasing in Thailand. We used a randomized controlled trial to examine the effectiveness of a self-help programme in reducing depression in people with depression in Chiang Mai Province in Thailand. Fifty-six individuals diagnosed with moderate depression participated. They were assigned randomly to an intervention (n= 27) or control (n= 29) group. The intervention group were given a self-help manual along with standard care and treatment, while the control group continued to receive standard care and treatment. Both groups were also given a short weekly telephone call. The findings showed statistically significant differences between the groups, and within the intervention group, in their depression levels. Between baseline and post-test, a sharp decrease in depression was evident in the intervention group, whereas the level of depression increased in the control group. Between post-test and follow-up, a decrease was apparent in depression in both groups. However, the intervention group showed a much lower level of depression than the control group. The results support the use of bibliotherapy as an adjunct to mental health nurses' and other professionals' work in caring for people with moderate depression in the community. http://www.ANZCTR.org.au/ACTRN12611000905965.aspx. © 2012 Blackwell Publishing.

Power, S.; Mirza, M.; Thakorlal, A.

PurposeThis prospective pilot study was undertaken to evaluate the feasibility and effectiveness of using a radiation absorbing shield to reduce operator dose from scatter during lower limb endovascular procedures.Materials and MethodsA commercially available bismuth shield system (RADPAD) was used. Sixty consecutive patients undergoing lower limb angioplasty were included. Thirty procedures were performed without the RADPAD (control group) and thirty with the RADPAD (study group). Two separate methods were used to measure dose to a single operator. Thermoluminescent dosimeter (TLD) badges were used to measure hand, eye, and unshielded body dose. A direct dosimeter with digital readout was also used tomore » measure eye and unshielded body dose. To allow for variation between control and study groups, dose per unit time was calculated.ResultsTLD results demonstrated a significant reduction in median body dose per unit time for the study group compared with controls (p = 0.001), corresponding to a mean dose reduction rate of 65 %. Median eye and hand dose per unit time were also reduced in the study group compared with control group, however, this was not statistically significant (p = 0.081 for eye, p = 0.628 for hand). Direct dosimeter readings also showed statistically significant reduction in median unshielded body dose rate for the study group compared with controls (p = 0.037). Eye dose rate was reduced for the study group but this was not statistically significant (p = 0.142).ConclusionInitial results are encouraging. Use of the shield resulted in a statistically significant reduction in unshielded dose to the operator’s body. Measured dose to the eye and hand of operator were also reduced but did not reach statistical significance in this pilot study.« less

Offering counseling and psychotherapy to patients with pedophilia is considered an essential part of sexual abuse prevention by many experts in the field. Yet, professionals' willingness to offer treatment might be compromised by stigmatizing attitudes towards these patients. In the present study, we developed and tested a 10-min online intervention (including educational material and a video about a person with pedophilia) to reduce stigma and increase motivation to work with this particular patient group. Psychotherapists in training were either assigned to the anti-stigma intervention group (n=68) or the control group (n=69) that received information about violence-free parenting. In the anti-stigma condition, agreement with the stereotypes controllability and dangerousness, anger, reduced pity and social distance were significantly reduced after the intervention, compared to the control group, while motivation to work with this group remained unchanged. The effects persisted, though slightly reduced in size, for perceived controllability, anger and social distance at follow-up. Our results suggest that stigmatizing attitudes, negative affective responses and social distance regarding people with pedophilia among psychotherapists in training can be positively influenced by a low-cost intervention. Practical implications of these findings for high quality health care and child sexual abuse prevention are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

Previously, outpatient Yoga programs for patients with chronic low back pain (CLBP) lasting several months have been found to reduce pain, analgesic requirement and disability, and improve spinal mobility. This study evaluated changes in pain, anxiety, depression and spinal mobility for CLBP patients on short-term, residential Yoga and physical exercise programs, including comprehensive yoga lifestyle modifications. A seven day randomized control single blind active study in an residential Holistic Health Centre in Bangalore, India, assigned 80 patients (37 female, 43 male) with CLBP to yoga and physical exercise groups. The Yoga program consisted of specific asanas and pranayamas for back pain, meditation, yogic counselling, and lectures on yoga philosophy. The control group program included physical therapy exercises for back pain, and matching counselling and education sessions. Group×time interactions (p<0.05) and between group differences (p<0.05) were significant in all variables. Both groups' scores on the numerical rating scale for pain reduced significantly, 49% in Yoga (p<0.001, ES=1.62), 17.5% in controls (p=0.005, ES=0.67). State anxiety (STAI) reduced 20.4% (p<0.001, ES=0.72) and trait anxiety 16% (p<0.001, ES=1.09) in the yoga group. Depression (BDI) decreased in both groups, 47% in yoga (p<0.001, ES=0.96,) and 19.9% in controls (p<0.001, ES=0.59). Spinal mobility ('Sit and Reach' instrument) improved in both groups, 50%, in yoga (p<0.001, ES=2.99) and 34.6% in controls (p<0.001, ES=0.81). Seven days intensive residential Yoga program reduces pain, anxiety, and depression, and improves spinal mobility in patients with CLBP more effectively than physiotherapy exercises.

Previous research studies have indicated that biofeedback treatment and relaxation techniques are effective in reducing psychological and physical symptoms (Hammond, 2005; Manzoni, G. M., Pagnini, F., Castelnuovo, G., & Molinari, E., 2008). However, dearth of studies has compared heart rate variability (HRV) biofeedback treatment and relaxation training to reduce trait anxiety. The objective of this study was to determine the effect of HRV biofeedback treatment and relaxation training in reducing trait anxiety compared to control group without any treatment using students in a science and engineering university of South Korea. For the present study, a total of 15 graduate students with moderate level of trait anxiety were recruited for 4 individual sessions every two weeks. They were randomly assigned into three groups: biofeedback treatment (n = 5), relaxation training (n = 5), and no treatment control group (n = 5). Our results revealed significant difference in change score of trait anxiety between the HRV biofeedback treatment and the no treatment control group. However, no significant difference was found between the relaxation training group and the no treatment control group. In addition, there was no significant difference between the HRV biofeedback treatment and the relaxation training. Results of the present study indicate that there is potential benefit in utilizing HRV biofeedback treatment for stress management programs and/or anxiety reduction treatment PMID:27099546

This study aimed to assess the efficacy of a rural community-based integrated intervention for early prevention and management of chronic obstructive pulmonary disease (COPD) in China. This 18-year cluster-randomized controlled trial encompassing 15 villages included 1008 patients (454 men and 40 women in the intervention group [mean age, 54 ± 10 years]; 482 men and 32 women in the control group [mean age, 53 ± 10 years]) with confirmed COPD or at risk for COPD. Villages were randomly assigned to the intervention or the control group, and study participants residing within the villages received treatment accordingly. Intervention group patients took part in a program that included systematic health education, smoking cessation counseling, and education on management of COPD. Control group patients received usual care. The groups were compared after 18 years regarding the incidence of COPD, decline in lung function, and mortality of COPD. COPD incidence was lower in the intervention group than in the control group (10% vs 16%, <0.05). A decline in lung function was also significantly delayed in the intervention group compared to the control group of COPD and high-risk patients. The intervention group showed significant improvement in smoking cessation compared with the control group, and smokers in the intervention group had lower smoking indices than in the control group (350 vs 450, <0.05). The intervention group also had a significantly lower cumulative COPD-related death rate than the control group (37% vs 47%, <0.05). A rural community-based integrated intervention is effective in reducing the incidence of COPD among those at risk, delaying a decline in lung function in COPD patients and those at risk, and reducing mortality of COPD.

xtensive blood loss after total knee arthroplasty (TKA) is common, and affected patients often require blood transfusions. Studies suggest that antifibrinolytic agents such as aminocaproic acid (ACA) reduce blood loss and blood transfusion rates in patients undergoing TKA. We conducted a study to evaluate whether a single intravenous 10-g dose of ACA given during primary unilateral TKA would decrease perioperative blood loss, raise postoperative hemoglobin levels, and reduce postoperative blood transfusion rates. We retrospectively reviewed the charts of 50 comparable cemented primary unilateral TKAs. Twenty-five patients had been given a single intraoperative 10-g dose of ACA (antifibrinolytic group), and the other 25 had not been given ACA (control group). Postoperative drain output was decreased significantly (P < .0001) in the antifibrinolytic group (155 mL) compared with the control group (410 mL), as was the number of units of blood transfused after surgery (antifibrinolytic group, 0 units; control group, 10 units; P < .002). There were no adverse events in the antifibrinolytic group. In TKA, perioperative blood loss and blood transfusion rates were reduced significantly in patients given a single intraoperative intravenous 10-g dose of ACA compared with patients not given antifibrinolytics. The positive effects of ACA were obtained without adverse events or complications.

Walsh, Amy T; Carmel, David; Harper, David; Grimshaw, Gina M

Using cognitive control to ignore distractions is essential for successfully achieving our goals. In emotionally-neutral contexts, motivation can reduce interference from irrelevant stimuli by enhancing cognitive control. However, attention is commonly biased towards emotional stimuli, making them potent distractors. Can motivation aid control of emotional distractions, and does it do so similarly for positive and negative stimuli? Here, we examined how task motivation influences control of distraction from positive, negative, and neutral scenes. Participants completed a simple perceptual task while attempting to ignore task-irrelevant images. One group received monetary reward for fast and accurate task performance; another (control) group did not. Overall, both negative (mutilation) and positive (erotic) images caused greater slowing of responses than neutral images of people, but emotional distraction was reduced with reward. Crucially, despite the different motivational directions associated with negative and positive stimuli, reward reduced negative and positive distraction equally. Our findings suggest that motivation may encourage the use of a sustained proactive control strategy that can effectively reduce the impact of emotional distraction.

The cancer-preventive activity of an extract of Withania somnifera (WS) roots was examined in female transgenic (MMTV/Neu) mice that received a diet containing the extract (750 mg/kg of diet) for 10 months. Mice in the treated group (N=35) had an average of 1.66 mammary carcinomas, and mice in the control group (N=33) had 2.48, a reduction of 33%. The average weights of the carcinomas were 2.36 g for mice in the treated group and 2.63 g for the controls, a difference of 10%. Labeling indices for Ki67 and proliferating cell nuclear antigen marker in mammary carcinomas of the treated group were 35% and 30% lower, respectively, than those of the corresponding control group. Expression of the chemokine was reduced by 50%. These results indicate that the root extract reduced the number of mammary carcinomas that developed and reduced the rate of cell division in the carcinomas. PMID:25368231

We investigated factors hypothesized to moderate the effects of cognitive behavioral group-based (CB group) and bibliotherapy depression prevention programs. Using data from two trials (N = 631) wherein adolescents (M age = 15.5, 62% female, 61% Caucasian) with depressive symptoms were randomized into CB group, CB bibliotherapy, or an educational brochure control condition, we evaluated the moderating effects of individual, demographic, and environmental factors on depressive symptom reductions and major depressive disorder (MDD) onset over 2-year follow-up. CB group and bibliotherapy participants had lower depressive symptoms than controls at posttest but these effects did not persist. No MDD prevention effects were present in the merged data. Relative to controls, elevated depressive symptoms and motivation to reduce depression amplified posttest depressive symptom reduction for CB group, and elevated baseline symptoms amplified posttest symptom reduction effects of CB bibliotherapy. Conversely, elevated substance use mitigated the effectiveness of CB group relative to controls on MDD onset over follow-up. Findings suggest that both CB prevention programs are more beneficial for youth with at least moderate depressive symptoms, and that CB group is more effective for youth motivated to reduce their symptoms. Results also imply that substance use reduces the effectiveness of CB group-based depression prevention. Copyright © 2015 Elsevier Ltd. All rights reserved.

The purpose of this study was to evaluate and compare the effectiveness of muscle-strengthening exercises (MS) and a walking program (WA) in reducing pain in patients with fibromyalgia. Ninety women, 30-55 years of age, diagnosed with fibromyalgia according to the American College of Rheumatology 1990 criteria, were randomized into 3 groups: WA Group, MS Group, and control group. Pain (visual analog scale) was evaluated as the primary outcome. Physical functioning (Fibromyalgia Impact Questionnaire, FIQ), health-related quality of life (Short-Form 36 Health Survey, SF-36), and use of medication were evaluated as secondary outcomes. Assessments were performed at baseline, 8, 16, and 28 weeks. Intention-to-treat and efficacy analyses were conducted. Sixty-eight patients completed the treatment protocol. All 3 groups showed improvement after the 16-week treatment compared to baseline. At the 28-week follow-up, pain reduction was similar for the WA and MS groups (P = 0.39), but different from the control group (P = 0.01). At the end of the treatment, 80% of subjects in the control group took pain medication, but only 46.7% in the WA and 41.4% in the MS groups. Mean FIQ total scores were lower for the WA and MS groups (P = 0.96) compared with the control group (P < 0.01). Patients in the WA and MS groups reported higher scores (better health status) than controls in almost all SF-36 subscales. MS was as effective as WA in reducing pain regarding all study variables; however, symptoms management during the follow-up period was more efficient in the WA group.

In pathogenesis of necrotizing enterocolitis (NEC), both oxidative stress and inflammation are considerable risk factors. The study was designed to evaluate whether administration of dexpanthenol (Dxp) is able to attenuate intestinal injury through the antioxidant and antiinflammatory mechanisms in a neonatal rat model of NEC. Forty newborn pups divided into four groups were included in the study: control, control+Dxp, NEC, and NEC+Dxp. NEC was induced by hyperosmolar formula and additionally the pups were exposed to hypoxia/hyperoxia and cold stress. They were sacrificed on postnatal day four, and their intestinal tissues were analyzed biochemically and histopathologically. Dxp caused a significant decrease in intestinal damage as determined by the histological score, villus height and number of goblet cells in NEC groups (p<0.0001). Tissue malondialdehyde, total oxidant status, and oxidative stress indexes levels were higher in the NEC group than in the control and control+Dxp groups (p<0.001). These values were reduced in the pups treated with Dxp (p≤0.004). Superoxide dismutase, glutathione peroxidase, and reduced glutathione activities were significantly reduced in the NEC group compared to the others (p<0.005). Treatment with Dxp significantly reduced elevations in tissue homogenate levels of tumor necrosis factor-α and interleukin-1β in the NEC+Dxp group (p=0.002 and p=0.01, respectively). Dexpanthenol seems to have antiinflammatory and antioxidant properties. Prophylaxis with Dxp has a potential to reduce the severity of intestinal damage in NEC in the animals.

To evaluate whether information and reassurance about low back pain (LBP) given to employees at the workplace could reduce sick leave. A Cluster randomized controlled trial with 135 work units of about 3,500 public sector employees in two Norwegian municipalities, randomized into two intervention groups; Education and peer support (EPS) (n = 45 units), education and "peer support and access to an outpatient clinic" (EPSOC) (n = 48 units), and a control group (n = 42 units). Both interventions consisted of educational meetings based on a "non-injury model" and a "peer adviser" appointed by colleagues. Employees in the EPSOC group had access to an outpatient clinic for medical examination and further education. The control group received no intervention. The main outcome was sick leave based on municipal records. Secondary outcomes were self-reported pain, pain related fear of movement, coping, and beliefs about LBP from survey data of 1,746 employees (response rate about 50 %). EPS reduced sick leave by 7 % and EPSOC reduced sick leave by 4 % during the intervention year, while sick leave in the control group was increased by 7 % during the same period. Overall, Rate Ratios (RR) were statistically significant for EPSOC (RR = .84 (C.I = 0.71-.99) but not EPS (RR = .92 (C.I = 0.78-1.09)) in a mixed Poisson regression analysis. Faulty beliefs about LBP were reduced in both intervention groups. Educational meetings, combined with peer support and access to an outpatient clinic, were effective in reducing sick leave in public sector employees.

Chronic obstructive pulmonary disease is an inflammatory lung disease mainly caused by tobacco smoke inhalation. Fifteen healthy adult male cats were categorized into 3 groups: (1) control group, (2) exposed to cigarette smoke (CS), and (3) exposed to CS treated with tiotropium. Increases in clinical signs and airway responsiveness in CS cats were found compared to control animals. The airway hyperresponsiveness and clinical signs were significantly attenuated by treatment with tiotropium. The CS-induced pulmonary release of interleukin-6, interleukin-8, monocyte chemotactic protein-1, and tumor necrosis factor alpha was reduced in the tiotropium group. Exposure to CS significantly increased total inflammatory cells number in bronchoalveolar lavage fluid, which was significantly attenuated by treatment with tiotropium. The number of macrophages, eosinophils and neutrophils and lymphocytes was increased after exposure to CS. Tiotropium significantly reduced the number of all these cells. Perivascular, peribronchiolar infiltration of inflammatory cells and Reid index increased in the CS group. Treatment with tiotropium significantly reduced these parameters to control level. Enhanced lipid peroxidation with concomitant reduction of antioxidants status was observed in the CS group. Tiotropium significantly reduced the serum, lung lavage, lung, and tracheal tissue lipid peroxides to near control levels. Tiotropium also decreased lung and tracheal protein leakage, and prevented the reduction of total antioxidant status in serum, lung lavage, lung and tracheal tissue of the CS group. Cigarette smoke increases airway responsiveness and inflammation in a cat model of CS induced lung inflammation. It can effectively be reduced by treatment with tiotropium.

The aim of the present study was to examine the effects of consumption of desserts with low glycemic index (GI) and low glycemic load (GL), as part of a balanced hypo-caloric diet, on anthropometric and biochemical parameters in patients with type 2 diabetes mellitus (T2DM). A total of 61 subjects with T2DM were randomly assigned to the intervention (n = 30) or to the control group (n = 31). Both groups followed the same hypo-caloric (-500 kcal) diet for 12 weeks. Consumption of four portions of low-GI/low-GL desserts/week was included in the diet in the intervention group while one portion of a favorite usual sweet/week was allowed to be consumed in the control group. Thirty subjects in the control and 28 subjects in the intervention group completed the trial. Body weight, body mass index, and waist circumference were reduced significantly in both groups. Arterial blood pressure, fasting blood glucose, glycosylated hemoglobin, insulin, and γ-GT were reduced significantly only in the intervention group; however, there were no significant differences between the two groups at endpoint. C-reactive protein was reduced in the intervention, and HDL cholesterol was also reduced in the control group; the reductions were significantly different at the end of the trial. No significant changes were observed in the other plasma lipids, uric acid, leptin, adiponectin, and interleukin-6 in either study group. Consumption of desserts with low GI/GL in a balanced hypo-caloric diet has a positive impact on anthropometric and metabolic parameters of patients with T2DM.

To assess the microbial effect of ozone gas on dentinal lesions in young permanent molars using the stepwise excavation. An experimental, controlled clinical trial was performed. The sample included 80 immature first permanent molars, showing deep occlusal carious cavities that were indicated for stepwise excavation. Following first step of dentin excavation, the sample was divided into test (ozone gas) and control (calcium hydroxide (Ca(OH) 2 ) base material) groups. One half of the cases in each group were evaluated for microbiological changes after 6 months, and the other half after 12 months. Mutans streptococci (MS), Lactobacilli, and Candida counts were significantly reduced immediately after ozone application in the test group (P ≤0.05). At the final assessment period, MS and Lactobacilli were significantly reduced in the test group (P ≤0.05). Meanwhile, the Candida counts were significantly reduced only in the test group of the 6 and 12 month-cases (P ≤0.05). Regarding the control group, the significant reduction in microbial count was observed with MS after 6 and 12 months (P ≤0.05). No significant differences were observed between test and control groups at different evaluation periods (P >0.05). Ozone gas had a significant antimicrobial effect in deep class I carious lesions.

Imbalance leading to falls is common in people with multiple sclerosis (PwMS). To evaluate the effects of a balance group exercise programme (CoDuSe) on balance and walking in PwMS (Expanded Disability Status Scale, 4.0-7.5). A multi-centre, randomized, controlled single-blinded pilot study with random allocation to early or late start of exercise, with the latter group serving as control group for the physical function measures. In total, 14 supervised 60-minute exercise sessions were delivered over 7 weeks. Pretest-posttest analyses were conducted for self-reported near falls and falls in the group starting late. Primary outcome was Berg Balance Scale (BBS). A total of 51 participants were initially enrolled; three were lost to follow-up. Post-intervention, the exercise group showed statistically significant improvement ( p = 0.015) in BBS and borderline significant improvement in MS Walking Scale ( p = 0.051), both with large effect sizes (3.66; -2.89). No other significant differences were found between groups. In the group starting late, numbers of falls and near falls were statistically significantly reduced after exercise compared to before ( p < 0.001; p < 0.004). This pilot study suggests that the CoDuSe exercise improved balance and reduced perceived walking limitations, compared to no exercise. The intervention reduced falls and near falls frequency.

In various countries preventive support groups are offered to children of mentally ill and/or addicted parents to reduce the risk that they will develop problems themselves. This study assessed the effectiveness of Dutch support groups for children aged 8-12 years old in terms of reducing negative cognitions; improving social support, competence, and parent-child interaction (direct intervention goals); and reducing emotional and behavioural problems (ultimate intervention aim). Children from 254 families were randomly assigned to the intervention or a control condition. Parents and children completed questionnaires at baseline and 3 and 6 months later. Emotional and behavioural problems of intervention group children were also assessed 1 year after the start. Univariate analyses of variance showed that children in the intervention group experienced a greater decrease in negative cognitions and sought more social support, immediately after participation and 3 months later, as compared to control group children. They also remained stable in their feelings of social acceptance (competence aspect) immediately after the intervention, whereas these feelings declined in control group children. The intervention and control groups both improved over time in terms of cognitions, competence, parent-child interaction and emotional and behavioural problem scores. Additional improvement in terms of problem scores was found in the intervention group 1 year after baseline. Further enhancement of effectiveness requires re-consideration of the support group goals; it should be studied whether the goals reflect the most important and influential risk and protective factors for this specific population. Besides, effects should be studied over a longer period.

To observe the efficacy differences between acupuncture combined with medication and medication alone for infertility patients with polycystic ovary syndrome (PCOS). According to random number table, a total of 60 infertility patients with PCOS were randomly assigned into an observation group and a control group, 30 cases in each one. The patients in the control group were treated with diane-35 from the 3rd day into menstruation, and one menstrual cycle was taken as a session of treatment. At the same time of using diane-35, the patients in the observation group were treated with acupuncture at Guanyuan (CV 4), Qihai (CV 6), Sanyinjiao (SP 6), Zusanli (ST 36), Zigong (EX-CA 1), Shenshu (BL 23), Pishu (BL 20), Weishu (BL 21) and Ganshu (BL 18) during non-menstruation period; the acupuncture was given once every two days, three treatments per week. The patients in both groups were treated for two sessions. The basic sex hormone and body mass index (BMI) were compared between the two groups before and after treatment. After ovulation induction treatment, the endometrial thickness, amount of mature follicle, ovulation rate, clinical pregnancy rate, occurrence rate of ovarian hyperstimulation syndrome (OHSS) and the number of early spontaneous abortion were compared between the two groups during ovulation. After treatment, the luteinizing hormone (LH), testosterone (T) and BMI reduced in the observation group (all P <0.05), while only LH reduced in the control group ( P <0.05). The reducing of estradiol (E 2 ), T and BMI in the observation group was more significant than that in the control group (all P <0.05). The ovulation rate was 93.3% (28/30) in the observation group, which was higher than 80.0% (24/30) in the control group ( P <0.05). The rate of clinical pregnancy was 43.3% (13/30) in the observation group, which was higher than 33.3% (10/30) in the control group ( P <0.05). The differences of endometrial thickness, amount of mature follicle, occurrence rate of OHSS and number of early spontaneous abortion were not significant between the two groups (all P >0.05). Acupuncture as adjunctive treatment could improve BMI, reduce the levels of LH, E 2 and T, increase ovulation reaction and effectively shorten reproduction cycles in infertility patients with PCOS.

To investigate the efficacy of mouse nerve growth factor (mNGF) in treating occupational hand-arm vibration disease (HAVD). Sixty-four patients with HAVD were equally and randomly divided into treatment group and control group. The control group was given Salvia miltiorrhiza Bunge and deproteinized extract of calf blood to improve circulation, and also given methylcobalamin tablets and vitamin B6 for neurotrophic treatment. In addition to the above treatments for the control group, the treatment group was also given 30 µg/d mNGF by intramuscular injection for two courses (4 weeks for each course) with a 15-day interval. Both the treatment group and the control group showed significant improvements in clinical symptoms and signs (hand numbness and pain, and reduced senses of touch, pain, and vibration), cold water loading test (CWLT), and electroneuromyography (ENMG) after treatments (P < 0.05). And the treatment group had significantly more improvements than the control group (P < 0.05). mNGF can significantly improve hand numbness and pain, reduced senses of touch, pain, and vibration, CWLT, and ENMG, so it has better clinical effect and safety in treating HAVD. Early diagnosis and treatment can improve the outcome of patients with HAVD.

This aim of the study is to determine whether the use of Seprafilm reduces the incidence and the medical costs of adhesive bowel obstruction (ABO) in children. Pediatric patients undergoing laparotomy were prospectively assigned to the Seprafilm group, n = 441). A historical control group consisted of children without using Seprafilm (n = 409). The incidence of ABO during a 24-month follow-up period was compared between the groups. To clarify the cost-benefit relations, expenses for Seprafilm and medical costs for hospitalization related to ABO in the Seprafilm group were compared with the ABO-associated hospitalization costs in the control group. The cumulative incidence rate of ABO in the control group was significantly higher than in the Seprafilm group (4.9% vs. 2.0%, p = 0.015). Nearly all cases that required adhesiolysis had adhesions to areas other than the incision in both groups. In cost-benefit analysis, cost per patient was $105 higher in the control group than in the Seprafilm group, but this did not reach significance (p = 0.63). Seprafilm reduces the incidence of ABO in the pediatric patients undergoing laparotomy. Although associated medical costs in the Seprafilm group were not significantly reduced, use of Seprafilm did not lead to an increase in cost. Wider range of Seprafilm application or an additional anti-adhesion device may help in preventing adhesion to areas other than the incision. Copyright © 2013 Elsevier Inc. All rights reserved.

Few studies have rigorously evaluated school-based interventions to reduce violence and substance use in high school students, especially Latinos. This study assessed the effects of a school-based program on reducing violence and substance use among primarily Latino high school students. Ninth-grade students at risk for violence and substance use were randomized to intervention or control groups. The intervention was based on an existing program developed for white and African American youth. Data on smoking, alcohol and drug use, fighting, and grades were collected at baseline and 4 and 8 months post enrollment. There were 55 students in the control and 53 in the intervention group; 74% of controls and 78% of intervention students were Latino. There were no significant changes in fighting, smoking, or alcohol or drug use, from baseline to 8-month follow-up, between the intervention and control group. Pre and post grade point average (GPA) decreased from 2.3 at baseline to 1.8 at follow-up (p<.01) in the intervention group, with no significant between-group changes in GPA from baseline to follow-up. This school-based program showed no reduction in violence or substance use. The findings suggest that a program targeting non-Latino youth may not be optimal for reducing violence and substance use in Latinos; greater attention to cultural appropriateness and racial/ethnic differences may be needed. There was a decrease in intervention-group GPA but no significant change compared with controls. Further studies of the impact of school-based substance use and violence prevention programs on academics, and the effectiveness of afterschool or community-based programs compared to school-based programs are needed.

Background Several cognitive behavioral interventions have been reported to reduce psychological symptoms in breast cancer (BC) patients. The goal of this study was to evaluate the effects of a yoga intervention in reducing depression and anxiety symptoms in BC patients. Methods This study was a randomized, partially blinded, controlled trial comparing a standardized yoga intervention to standard care. It was conducted at three medical centers in Montreal, Canada. Eligible patients were women diagnosed with stage I-III BC receiving chemotherapy. Participants were randomly assigned to receive yoga intervention immediately (experimental group, n=58) or after a waiting period (n=43 control group). The Bali Yoga Program for Breast Cancer Patients (BYP-BC) consisted of 23 gentle Hatha asanas (poses), 2 prayanamas (breathing techniques), shavasanas (relaxation corpse poses) and psychoeducational themes. Participants attended eight weekly sessions lasting 90 min each and received a DVD for home practice with 20- and 40-min sessions. Participants in the wait list control group received standard care during the 8-week waiting period. Results A total of 101 participants took part in the final intention-to-treat analyses. The repeated measures analyses demonstrated that depression symptoms increased in the control group (p=0.007), while no change was reported in the BYP-BC group (p=0.29). Also, depression symptoms decreased in the WL control group after receiving the BYP-BC intervention (p=0.03). Finally, there was no statistical significance in terms of anxiety symptoms (p=0.10). Conclusions Results support the BYP-BC intervention as a beneficial means of reducing and preventing the worsening of depression symptoms during chemotherapy treatment.

This study was conducted to investigate the effect of dietary grape skin on lipid peroxidation and antioxidant defense system in rats fed high fat diet. The Sprague-Dawley rats were fed either control (5% fat) diet or high fat (25% fat) diet which was based on AIN-93 diet for 2 weeks, and then they were grouped as control group (C), control + 5% grape skin group (CS), high-fat group (HF), high fat + 5% grape skin group (HFS) with 10 rats each and fed corresponding diets for 4 weeks. The hepatic thiobarbituric acid reacting substances (TBARS) were increased in high fat group as compared with control group, but reduced by grape skin. The serum total antioxidant status, and activities of hepatic catalase and superoxide dismutase, xanthine oxidase and glucose-6-phosphatase were increased by supplementation of grape skin. Glutathione peroxidase activity was significantly higher in CS group than in C group. Grape skin feeding tended to increase the concentration of total glutathione, especially in control group. The ratio of reduced glutathione to oxidized glutathione was lower in high fat groups than in control groups. The ratio was increased by dietary supplementation of grape skin in control group. These results suggest that dietary supplementation of grape skin would be effective on protection of oxidative damage by lipid peroxidation through improvement of antioxidant defense system in rats fed high fat diet as well as rats with low fat diet.

The purpose was to find better augmented visual feedback frequency (100% or 67%) for learning a balance task in adolescents. Thirty subjects were divided randomly into a control group, and 100% and 67% feedback groups. The three groups performed pretest (3 trials), practice (12 trials), posttest (3 trials) and retention (3 trials, 24 hours later). The reduced feedback group showed lower RMS in the posttest than in the pretest (p = 0.04). The control and reduced feedback groups showed significant lower median frequency in the posttest than in the pretest (p < 0.05). Both feedback groups showed lower values in retention than in the pretest (p < 0.05). Even when the effect of feedback frequency could not be detected in motor learning, 67% of the feedback was recommended for motor adaptation.

To observe the effects of bloodletting pricking, cupping and surrounding acupuncture on blood inflammation-related indices in patients with acute herpes zoster (HZ), and to explore the mechanism of pain control and treatment. A total of 60 patients were randomly divided into an observation group and a control group, 30 cases in each one. In the observation group, the patients were treated with bloodletting pricking at herpes, followed by cupping treatment; also the surrounding acupuncture was performed at injured skin. The treatment was given once a day and once every other day after the first 3 days; totally one-week treatment was given. In the control group, the patients were treated with intravenous drip of acyclovir and oral administration of vitamin B1 and B12, once a day for total one week. The visual analogue scale (VAS) and percentages of neutrophil, lymphocyte in peripheral and local blood were observed before and after treatment in the two groups. After treatment, the score of VAS was significantly reduced in both groups (both P < 0.05); compared with the control group, the score of VAS and the time of pain relieve were significantly improved in the observation group (P < 0.01, P < 0.05). Compared before treatment, the percentages of lymphocyte in peripheral and local blood were reduced after treatment (both P < 0.05) and the percentages of neutrophil in local blood were increased (both P < 0.05). The lymphocyte in local blood was also reduced after treatment in the control group (P < 0.05); compared with peripheral blood in the observation group and local blood in the control group, the percentages of lymphocyte in local blood were reduced (both P < 0.05). The efficacy of bloodletting pricking, cupping and surrounding acupuncture on acute herpes zoster is positive, and it can significantly lower the number of lymphocytes in the local blood and increase the number of neutrophil, which is likely to be one of the anti-virus mechanisms.

Recent animal studies demonstrate that compulsive cocaine seeking strongly reduces prelimbic frontal cortex activity, while optogenetic stimulation of this brain area significantly inhibits compulsive cocaine seeking, providing a strong rationale for applying brain stimulation to reduce cocaine consumption. Thus, we employed repetitive transcranial magnetic stimulation (rTMS), to test if dorsolateral prefrontal cortex (DLPFC) stimulation might prevent cocaine use in humans. Thirty-two cocaine-addicted patients were randomly assigned to either the experimental group (rTMS) on the left DLPFC, or to a control group (pharmacological agents) during a 29-day study (Stage 1). This was followed by a 63-day follow-up (Stage 2), during which all participants were offered rTMS treatment. Amongst the patients who completed Stage 1, 16 were in the rTMS group (100%) and 13 in the control group (81%). No significant adverse events were noted. During Stage 1, there were a significantly higher number of cocaine-free urine drug tests in the rTMS group compared to control (p=0.004). Craving for cocaine was also significantly lower in the rTMS group compared to the controls (p=0.038). Out of 13 patients who completed Stage 1 in the control group, 10 patients received rTMS treatment during Stage 2 and showed significant improvement with favorable outcomes becoming comparable to those of the rTMS group. The present preliminary findings support the safety of rTMS in cocaine-addicted patients, and suggest its potential therapeutic role for rTMS-driven PFC stimulation in reducing cocaine use, providing a strong rationale for developing larger placebo-controlled studies.

2014-01-01

The objectives of this study were to examine whether a leisure education program could facilitate leisure competence among older adults and whether it could also reduce their stress. A pre-test-post-test randomized experimental design was conducted. Subjects were randomly assigned to either an experimental group (n = 30) or a control group (n = 30). A leisure education program was used to serve as the intervention. A day before this experiment was carried out, pre-test data were collected using leisure competence and stress scales. Thirty minutes after this experiment ended, post-test data were collected using the same scales. These data were analyzed using an analysis of covariance. The results indicated that the average post-test scores of leisure competence in the experimental group were significantly higher than those in the control group and that the average post-test scores of stress in the experimental group were significantly lower than those in the control group. Healthcare practitioners should adopt the provision of leisure education as a priority to facilitate leisure competence and reduce stress among older adults.

The aim of the present study was to assess the efficacy of a thrombin-based topical haemostatic in reducing blood requirements after total knee replacement (TKR) revision surgery. This prospective, randomized, controlled study was designed to evaluate the haemostatic efficacy and safety of a thrombin-based topical haemostatic (Floseal) versus standard treatment in patients receiving total knee revision arthroplasty. The decrease in haemoglobin values postsurgery and the blood units transfused were recorded. The decision to transfuse was made by a surgeon blinded to the patient's group allocation. Forty-eight patients were enroled in the study; twenty-four patients each were randomized to the treatment and control groups, respectively. The median decrease in haemoglobin concentration on the first postoperative day was 2.2 g/dL in the treatment group and 2.7 g/dL in the control group. A significant reduction in units of blood transfused was also observed in the treatment group compared with the control group [1.1 ± 1.13 (range 0-4) vs. 1.9 ± 1.41 (range 0-5) blood units; P = 0.04]. No major treatment-related adverse events were recorded in the study. This study shows that a thrombin-based topical haemostatic reduces the need for blood transfusion in TKR revision surgery. A thrombin-based topical haemostatic agent can be an appropriate solution to enhance haemostasis and vessel sealing at the operative site in TKR revision surgery, in order to reduce the need for blood transfusion after surgery.

We hypothesized that prophylactic administration of an appropriate antibiotic following each delayed intensification (DI) in children with acute lymphoblastic leukemia (ALL) would reduce the episodes of fever and bacteremia associated with neutropenia, and hence reduce both the rate and duration of hospitalization. All patients in the study were treated according to a modified Medical Research Council United Kingdom ALL XI (MRC UKALL XI) protocol utilizing three DI courses. Between June and December 2000 patients received prophylactic ciprofloxacin following DI courses. The rates of hospitalization and bacteremias were compared to ALL patients who had received between one and three DI courses prior to June 2000. There were 69 patients who received a total of 194 DIs (controls 130; study group 64). The rate of hospitalization was 90% in the controls and 58% in the study group (P < 0.001). The median hospital stay was 10.1 days for controls and 6.0 for the study group (P < 0.001). Intensive care unit admissions were reduced from 12 to 1.5% (P = 0.02). The overall rate of proven bacteremia was reduced from 22 to 9% (P = 0.028). There were no Gram-negative bacteremias in the study group compared to 10 (7.7%) in the controls (P < 0.001). Compared to historical controls, patients in this study receiving prophylactic ciprofloxacin had a reduced rate and duration of hospitalization and incidence of Gram-negative bacteremia.

Television viewing has been associated with increased violence in play and higher rates of obesity. Although there are interventions to reduce television viewing by school-aged children, there are none for younger children. To develop and evaluate an intervention to reduce television viewing by preschool children. Randomized controlled trial conducted in 16 preschool and/or day care centers in rural upstate New York. Children aged 2.6 through 5.5 years. Children attending intervention centers received a 7-session program designed to reduce television viewing as part of a health promotion curriculum, whereas children attending the control centers received a safety and injury prevention program. Change in parent-reported child television/video viewing and measured growth variables. Before the intervention, the intervention and control groups viewed 11.9 and 14.0 h/wk of television/videos, respectively. Afterward, children in the intervention group decreased their television/video viewing 3.1 h/wk, whereas children in the control group increased their viewing by 1.6 h/wk, for an adjusted difference between the groups of -4.7 h/wk (95% confidence interval, -8.4 to -1.0 h/wk; P =.02). The percentage of children watching television/videos more than 2 h/d also decreased significantly from 33% to 18% among the intervention group, compared with an increase of 41% to 47% among the control group, for a difference of -21.5% (95% confidence interval, -42.5% to -0.5%; P =.046). There were no statistically significant differences in children's growth between groups. This study is the first to show that a preschool-based intervention can lead to reductions in young children's television/video viewing. Further research is needed to determine the long-term effects associated with reductions in young children's television viewing.

The clinical value of soleus muscle H-reflex monitoring in general anesthesia percutaneous interlaminar approach was investigated. A total of 80 cases with unilateral L5-S1 disc herniation between January 2015 and October 2016 were randomly divided into control group (without soleus muscle H-reflex monitoring, n=40) and observation group (with soleus muscle H-reflex monitoring, n=40). Results showed that the operation time of the observation group was shorter than that of the control group (P<0.05), and the blood loss during the operation was less than that of the control group (P<0.05). The length of postoperative hospital stay was shorter than that of the control group (P<0.05). At 24 h after operation, the amplitude of H-reflex in diseased side soleus muscle was significantly lower than that in healthy side (P<0.05). The preoperative, postoperative and 24 h postoperatively, the latency of H-reflex in diseased side soleus muscle was shorter than that of healthy side (P<0.05). The latency and amplitude of H-reflex latency in soleus muscle were significantly lower (P<0.05), and the height of intervertebral space in observation group was significantly higher than that in control group (P<0.05). The total percentage of postsurgical sensory dysfunction, dyskinesia, post-root canal stenosis, disc herniation and cerebrospinal fluid leakage was lower than that of the control group (P<0.05). Japanese Orthopaedic Association score of the observation group was significantly higher at 1 month, and 1 year after operation lower than the control group (P<0.05). Taken together, soleus muscle H-reflex monitoring can effectively reduce the damage to the nerve roots under percutaneous endoscopic intervertebral endoscopic surgery under general anesthesia, improve the accuracy of surgery, reduce the complications, shorten the operation time and reduce the surgical bleeding, which is more beneficial to patients smooth recovery.

Randomised controlled trial of a text messaging intervention for reducing processed meat consumption: The mediating roles of anticipated regret and intention.

The present study aimed to extend the literature on text messaging interventions involved in promoting healthy eating behaviours. The theoretical framework was the Theory of Planned Behaviour (TPB). A randomized controlled trial was used to test the impact of daily text messages compared to no message (groups) for reducing processed meat consumption (PMC) over a 2 week period, testing the sequential mediation role of anticipated regret and intention on the relationship between groups and PMC reduction. PMC and TPB variables were assessed both at Time 1 and Time 2. Participants were Italian undergraduates (at Time 1 N = 124) randomly allocated to control and message condition groups. Undergraduates in the message condition group received a daily SMS, which focused on anticipated regret and urged them to self-monitor PMC. Participants in the control group did not receive any message. Those who completed all measures at both time points were included in the analyses (N = 112). Findings showed that a daily messaging intervention, controlling for participants' past behaviour, reduced self-reported consumption of PMC. Mediation analyses indicated partial serial mediation via anticipated regret and intentions. The current study provided support for the efficacy of a daily messaging intervention targeting anticipated regret and encouraging self-monitoring in decreasing PMC. Outcomes showed the important mediating role of anticipated regret and intentions for reducing PMC. Copyright © 2017 Elsevier Ltd. All rights reserved.

This trial compared the effects of lavender and bitter orange on anxiety in postmenopausal women. This trial was conducted in 2015. Eligible postmenopausal women were allocated into one of two intervention groups or a control group (n = 52 per group) in a 1:1:1 ratio using a randomized block design. Intervention groups received 500 mg capsules containing only bitter orange or lavender flower powder, and the control group received 500 mg capsules containing starch. The Spielberger's State -Trait Anxiety Inventory (STAI) was used before and eight weeks after starting the intervention. Data analyses were based on intention to treat. A one-way ANOVA showed no significant difference in mean state anxiety (P = 0.254) and trait anxiety (p = 0.972) score among the three groups before the intervention. The general linear model, adjusted for baseline state and trait anxiety scores and confounding factors, showed significant differences among the groups in the mean state anxiety (P = 0.010) and trait anxiety (p = 0.041) score after eight weeks of treatment. Bitter orange significantly reduced the mean state-anxiety scores compared with the control group [Adjusted Mean Difference (aMD): -1.99 (95% Confidence Interval, -3.64 to -0.34)]. Lavender significantly reduced the mean state-anxiety scores compared with the control group as well [aMD: -2.45 (95% CI -4.13 to -0.77)] and Bitter orange significantly reduced the mean trait-anxiety scores compared with the control group [aMD: -1.76 (95% CI -3.45 to -0.06)]. Lavender significantly reduced the mean trait-anxiety scores compared with the control group as well [aMD: -2.05 (95% CI -3.76 to -0.33)]. There was no significant difference between bitter orange and lavender groups after intervention in the mean trait-anxiety (p = 0.731) or state-anxiety (p = 0.578) scores. The positive effect of bitter orange and lavender on anxiety in postmenopausal women suggests that they can be used to decrease anxiety in such women. Copyright © 2018 Elsevier Ltd.

Irrational antibiotic use for respiratory tract infections (RTI) is a major driver of bacterial resistance. The aim of this study was to evaluate the effect of a multifaceted peer-group based intervention aiming to reduce RTI-related antibiotic prescriptions in family practice. This was a cluster randomized controlled trial with pre- and follow-up measurement. The intervention was implemented through PharmacoTherapy Audit Meetings (PTAM) in which family physicians (FPs) and pharmacists collaborate. Four PTAM groups received the intervention consisting of: (1) FP communication skills training, including communication about delayed prescribing; (2) implementation of antibiotic prescribing agreements in FPs' Electronic Prescribing Systems; (3) quarterly feedback figures for FPs. Four other PTAM groups were matched controls. Primary outcome measure was the number of RTI-related antibiotic prescriptions after the intervention, assessed with multilevel linear regression analyses. Total number and number of prescriptions stratified by age (under/over 12 years) were analysed. At baseline, the average total number of RTI-related antibiotic prescriptions per 1,000 patients was 207.9 and 176.7 in the intervention and control PTAM groups, respectively. At follow-up, FPs in both the intervention and control groups prescribed significantly less antibiotics. For adolescents and adults, the drop in number of antibiotic prescription was significantly larger in the intervention groups (-27.8 per 1,000 patients) than the control groups (-7.2 per 1,000 patients; P<0.05). This multifaceted peer-group-based intervention was effective in reducing the number of RTI-related antibiotic prescriptions for adolescents and adults. To affect antibiotic prescribing in children other methods are needed.

Acquisition of complex skills is a universal feature of human behavior that has been conceptualized as a process that starts with intense resource dependency, requires effortful cognitive control, and ends in relative automaticity on the multi-faceted task. The present study examined the effects of different theoretically based training strategies on cortical recruitment during acquisition of complex video game skills. Seventy-five participants were recruited and assigned to one of three training groups: (1) Fixed Emphasis Training (FET), in which participants practiced the game, (2) Hybrid Variable-Priority Training (HVT), in which participants practiced using a combination of part-task training and variable priority training, or (3) a Control group that received limited game play. After 30 h of training, game data indicated a significant advantage for the two training groups relative to the control group. The HVT group demonstrated enhanced benefits of training, as indexed by an improvement in overall game score and a reduction in cortical recruitment post-training. Specifically, while both groups demonstrated a significant reduction of activation in attentional control areas, namely the right middle frontal gyrus, right superior frontal gyrus, and the ventral medial prefrontal cortex, participants in the control group continued to engage these areas post-training, suggesting a sustained reliance on attentional regions during challenging task demands. The HVT group showed a further reduction in neural resources post-training compared to the FET group in these cognitive control regions, along with reduced activation in the motor and sensory cortices and the posteromedial cortex. Findings suggest that training, specifically one that emphasizes cognitive flexibility can reduce the attentional demands of a complex cognitive task, along with reduced reliance on the motor network.

Our previous study found that Chinese yellow wine could inhibit the production of homocysteine (HCY) induced extracellular matrix metalloproteinase-2 (MMP-2) in the cultured rat vascular smooth muscle cells. Little is known about the relationship between Chinese yellow wine and atherosclerosis or MMP-2 in vivo. Thirty-two LDL Receptor knockout mice on a high-fat and L-methionine diet developed plasma hyperhomocysteinemia and atherosclerosis. They were randomly divided into yellow wine group (n = 8), red wine group (n = 8), ethanol group (n = 8), and control group (n = 8), they were sacrificed after 14 weeks. There were no significant differences with plasma total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) levels in the four groups. Plasma HCY was significantly decreased in the yellow wine group compared to the other three groups (P < 0.01). Yellow wine and red wine groups significantly reduced the atherosclerosis lesion area compared to ethanol and control groups (P < 0.001). However, there was no significant discrepancy between the yellow wine group and red wine group. Compared to the control group and ethanol group, the production of MMP-2 reduced 26.8% and 23.6% in the aortic sinus and the activation of MMP-2 reduced 32.6% and 27.3% in the aortic arch in the yellow wine group; the production of MMP-2 reduced 25.7% and 22.4% in the aortic sinus and the activation of MMP-2 reduced 30.2% and 26.6% in the aortic arch in the red wine group. These results suggest that Chinese yellow wine and red wine can inhibit MMP-2 and improve atherosclerosis, and maybe both Chinese yellow wine and red wine have beneficial effects on cardiovascular disease by inhibiting MMP-2.

To evaluate the effectiveness of autologous fibrin tissue adhesive (auto-FTA) in reducing blood loss during cementless total hip arthroplasty (THA). From September 2000 to August 2001, 100 patients who predonated 400 ml of autologous blood were randomised to undergo either standard treatment with auto-FTA (auto-FTA group) or standard treatment alone (control group). The volume of postoperative blood loss and the decrease in haemoglobin level were measured. All patients were followed up for 3 years to evaluate the rate of bone ingrowth and heterotopic ossification. The mean postoperative blood loss was 580 ml (standard deviation [SD], 240 ml) in the auto-FTA group and 810 ml (SD, 341 ml) in the control group; the difference was significant (230 ml, p<0.001). The decrease in haemoglobin concentration was 17 g/l (SD, 11 g/l) in the auto-FTA group and 22 g/l (SD, 12 g/l) in the control group. The difference was significant (5 g/l, p=0.03). The percentage of total blood loss of >1200 ml in any single patient was significantly lower in the auto-FTA group (4%) than in the control group (20%) [p=0.01]. Auto-FTA is a safe and effective means of reducing perioperative blood loss in THA.

Currently, no clinical or animal studies have been performed to establish the relationship between airway humidification and mechanical ventilation-induced lung inflammatory responses. Therefore, an animal model was established to better define this relationship. Rabbits (n = 40) were randomly divided into 6 groups: control animals, sacrificed immediately after anesthesia (n = 2); dry gas group animals, subjected to mechanical ventilation for 8 h without humidification (n = 6); and experimental animals, subjected to mechanical ventilation for 8 h under humidification at 30, 35, 40, and 45°C, respectively (n = 8). Inflammatory cytokines in the bronchi alveolar lavage fluid (BALF) were measured. The integrity of the airway cilia and the tracheal epithelium was examined by scanning and transmission electron microscopy, respectively. Peripheral blood white blood cell counts and the wet to dry ratio and lung pathology were determined. Dry gas group animals showed increased tumor necrosis factor alpha levels in BALF compared with control animals (P < .05). The tumor necrosis factor alpha and interleukin-8 levels in the BALF reached baseline levels when the humidification temperature was increased to 40°C. Scanning and transmission electron microscopy analysis revealed that cilia integrity was maintained in the 40°C groups. Peripheral white blood cell counts were not different among those groups. Compared with control animals, the wet to dry ratio was significantly elevated in the dry gas group (P < .05). Moreover, humidification at 40°C resulted in reduced pathologic injury compared with the other groups based on the histologic score. Pathology and reduced inflammation observed in animals treated at 40°C was similar to that observed in the control animals, suggesting that appropriate humidification reduced inflammatory responses elicited as a consequence of mechanical ventilation, in addition to reducing damage to the cilia and reducing water loss in the airway.

Childhood abuse is associated with abnormalities in brain structure and function. Few studies have investigated abuse-related brain abnormalities in medication-naïve, drug-free youth that also controlled for psychiatric comorbidities by inclusion of a psychiatric control group, which is crucial to disentangle the effects of abuse from those associated with the psychiatric conditions. Cortical volume (CV), cortical thickness (CT) and surface area (SA) were measured in 22 age- and gender-matched medication-naïve youth (aged 13-20) exposed to childhood abuse, 19 psychiatric controls matched for psychiatric diagnoses and 27 healthy controls. Both region-of-interest (ROI) and whole-brain analyses were conducted. For the ROI analysis, the childhood abuse group compared with healthy controls only, had significantly reduced CV in bilateral cerebellum and reduced CT in left insula and right lateral orbitofrontal cortex (OFC). At the whole-brain level, relative to healthy controls, the childhood abuse group showed significantly reduced CV in left lingual, pericalcarine, precuneus and superior parietal gyri, and reduced CT in left pre-/postcentral and paracentral regions, which furthermore correlated with greater abuse severity. They also had increased CV in left inferior and middle temporal gyri relative to healthy controls. Abnormalities in the precuneus, temporal and precentral regions were abuse-specific relative to psychiatric controls, albeit at a more lenient level. Groups did not differ in SA. Childhood abuse is associated with widespread structural abnormalities in OFC-insular, cerebellar, occipital, parietal and temporal regions, which likely underlie the abnormal affective, motivational and cognitive functions typically observed in this population.

The objective of this study was to evaluate the effect of reduced-calorie avocado paste on lipid serum profile, insulin sensitivity, and hepatic steatosis in rats fed a hypercholesterolemic-high fructose diet. Thirty five male Wistar rats were randomly separated in five groups: Control group (ground commercial diet); hypercholesterolemic diet plus 60% fructose solution (HHF group); hypercholesterolemic diet plus 60% fructose solution supplemented with avocado pulp (HHF+A group); hypercholesterolemic diet plus 60% fructose solution supplemented with reduced-calorie avocado paste (HHF+P group); and hypercholesterolemic diet plus 60% fructose solution supplemented with a reduced-calorie avocado paste plus fiber (HHF+FP group). The A, P, and FP were supplemented at 2 g/kg/d. The study was carried out for seven weeks. Rats belonging to the HHF group exhibited significantly (P ≤ 0.05) higher total cholesterol, triglycerides, and insulin levels in serum as well as lower insulin sensitivity than the control group. Supplementation with reduced-calorie avocado paste showed a significant (P ≤ 0.05) decrease in total cholesterol (43.1%), low-density lipoprotein (45.4%), and triglycerides (32.8%) in plasma as well as elevated insulin sensitivity compared to the HHF group. Additionally, the liver enzymes alanine aminotransferase and aspartate aminotransferase decreased significantly in the HHF-P group (39.8 and 35.1%, respectively). These results are likely due to biocompounds present in the reduced-calorie avocado paste, such as polyphenols, carotenoids, chlorophylls, and dietary fibre, which are capable of reducing oxidative stress. Therefore, reduced-calorie avocado paste attenuates the effects of a hypercholesterolemic-high fructose diet in rats.

To develop, pilot, and evaluate a workplace intervention to reduce sickness absence, based on a demand-control-support model of job strain. Changes in the working arrangements of hospital cleaning staff were introduced with the aim of increasing their control over work and the support received at work. The study design was quasi-experimental, with 221 cleaning staff in the intervention group and 91 catering staff in the control group. The dependent variable was the difference in percentage monthly sickness absence between the 12 months preceding and following the intervention. Differences in sickness absence between staff groups for each month after the intervention were compared with differences between staff groups for the equivalent month one year prior to it. There was a significant reduction in the difference in sickness absence rates between the intervention and control group of 2.3% in the six months after the intervention, compared to the six months before. The difference was not maintained at 12 months. These results suggest that a workplace intervention aimed at increasing control and support at work has a small effect on reducing sickness absence among hospital cleaning staff in the short term. Future research should seek to replicate this effect in larger, experimental studies, analyse postulated mediators of such theory based interventions, and develop interventions that maintain improvement.

To evaluate the efficacy of orally administered Saccharomyces boulardii (S. boulardii) for reducing the incidence and severity of necrotizing enterocolitis (NEC) in very low-birth-weight (VLBW) infants. A prospective, randomised controlled trial was conducted in infants with gestational age ≤32 weeks and birth weight ≤1500 g. The study group received S. boulardii supplementation, and the control group did not. The primary outcomes were death or NEC (Bell's stage ≥2), and secondary outcomes were feeding intolerance and clinical or culture-proven sepsis. A total of 271 infants were enrolled in the study, 135 in the study group and 136 in the control group. There was no significant difference in the incidence of death (3.7% vs. 3.6%, 95% CI of the difference, -5.20-5.25; p = 1.0) or NEC (4.4% vs. 5.1%, 95% CI, -0.65-5.12; p = 1.0) between the groups. However, feeding intolerance and clinical sepsis were significantly lower in the probiotic group compared with control. Although Saccharomyces boulardii supplementation at a dose of 250 mg/day was not effective at reducing the incidence of death or NEC in VLBW infants, it improved feeding tolerance and reduced the risk of clinical sepsis. ©2013 Foundation Acta Paediatrica.

Abstract Background One of the most important factors affecting relapse of addiction is craving beliefs of substance use. The goal of the present study was assessment of the effectiveness of coping skills education program to reduce craving beliefs among opium addicts. Methods In a randomized controlled trial, during September 2011 to August 2012, 70 opium addicted men referred to the Behavioral Disorders and Substance Abuse Research Center in Hamadan, western Iran were assigned to intervention group (receiving coping skills education program) and control groups. The study information was analyzed using SPSS software. Results Regarding craving beliefs for continuing drug use, the two groups had similar scales at the beginning of interventional program, while the level of these beliefs was significantly reduced in the intervention group (P= 0.002), but not in the control group (P= 0.105). Also, a significant correlation was also revealed between taking advantage of the educational program and increase awareness of the signs of relapse in the intervention group (P=0.003) that was not revealed in the control (P= 0.174). On the other hand, executing coping skills education program led to reducecraving beliefs and improve knowledge towards signs of relapse. Conclusion Our findings demonstrate positive impact of coping skills education program after detoxification process on decrease of craving beliefs among opium addicts. PMID:26060622

We aimed to evaluate the effect of a decision aid (DA) with patient narratives on decisional conflict in surgery choice for Japanese women with early-stage breast cancer. Two hundred ten women with early-stage breast cancer were randomly assigned to an intervention or control group. Groups 1 and 2 received standard information and a DA, with or without patient narratives, and Group 3 received standard information (control) before surgery choice. At baseline, post-intervention (Time 2), and 1 month after surgery (Time 3), we evaluated decisional conflict as the primary outcome using a decisional conflict scale (DCS). Sidak corrections for multiple comparisons in analysis of covariate were used to compare Time 2 and Time 3 DCS mean scores between each pair of groups. At Time 3, decisional conflict was significantly reduced for Group 1 vs control (P=0.021, Cohen's d =0.26) and Group 2 vs control (P=0.008, Cohen's d=0.40). The DAs with and without patient narratives are equivalently effective at reducing postoperative decisional conflict in Japanese women with early-stage breast cancer. The DAs with and without patient narratives can be used in clinical practice for women with early-stage breast cancer. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Recent several observational studies have reported that high salt intake is associated with obesity. But it is unclear whether salt intake itself induce obesity or low salt diet can reduce body fat mass. We investigated whether a low salt diet can reduce body weight and fat amount. The randomized, open-label pilot trial was conducted at a single institution. A total of 85 obese people were enrolled. All participants were served meals three times a day, and provided either a low salt diet or control diet with same calorie. Visceral fat was measured with abdominal computer tomography, while body fat mass and total body water was measured with bio-impedance. Reductions in body weight (-6.3% vs. -5.0%, p = 0.05) and BMI (-6.6% vs. -5.1%, p = 0.03) were greater in the low salt group than in the control group. Extracellular water and total body water were significantly reduced in the low salt group compared to the control group. However, changes in body fat mass, visceral fat area, and skeletal muscle mass did not differ between the two groups. Changes in lipid profile, fasting glucose, and HOMA-IR did not differ between the two groups. A two-month low salt diet was accompanied by reduction of body mass index. However, the observed decrease of body weight was caused by reduction of total body water, not by reduction of body fat mass or visceral fat mass.

The aim of this study was to evaluate the potential effects of an insoluble dietary fiber from carob pod (IFC) (1 g ⋅ kg(-1) ⋅ d(-1) in the diet) on alterations associated with atherosclerosis in rabbits with dyslipidemia. Male New Zealand rabbits (n = 30) were fed the following diets for 8 wk: 1) a control diet (SF412; Panlab) as a control group representing normal conditions; 2) a control supplemented with 0.5% cholesterol + 14% coconut oil (DL) (SF302; Panlab) for 8 wk as a dyslipidemic group; and 3) a control containing 0.5% cholesterol + 14% coconut oil plus IFC (1 g ⋅ kg(-1) ⋅ d(-1)) (DL+IFC) for 8 wk. IFC was administered in a pellet mixed with the DL diet. The DL-fed group developed mixed dyslipidemia and atherosclerotic lesions, which were associated with endothelial dysfunction, inflammation, and fibrosis. Furthermore, sirtuin-1 (SIRT1) and peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) protein expression in the aorta were reduced to 77% and 63% of the control group, respectively (P < 0.05), in these rabbits. Administration of IFC to DL-fed rabbits reduced the size of the aortic lesion significantly (DL, 15.2% and DL+IFC, 2.6%) and normalized acetylcholine-induced relaxation (maximal response: control, 89.3%; DL, 61.6%; DL+IFC, 87.1%; P < 0.05) and endothelial nitric oxide synthase expression (DL, 52% and DL+IFC, 104% of the control group). IFC administration to DL-fed rabbits also reduced cluster of differentiation 36 (DL, 148% and DL+IFC, 104% of the control group; P < 0.05), plasminogen activator inhibitor-1 (DL, 141% and DL+IFC, 107% of the control group), tumor necrosis factor-α (DL, 166% and DL+IFC, 120% of the control group), vascular cell adhesion molecule-1 (DL, 153% and DL+IFC, 110% of the control group), transforming growth factor-β (DL, 173% and DL+IFC, 99% of the control group), and collagen I (DL, 157% and DL+IFC, 112% of the control group) in the aorta. These effects were accompanied by an enhancement of SIRT1 and PGC-1α (160% and 121% of the control group, respectively; P < 0.05) vascular expression. In summary, we demonstrated for the first time, to our knowledge, that administration of IFC reduces the development of atherosclerosis in rabbits. This effect seems to be related to an improvement in endothelial function and a reduction of inflammation and fibrosis, most probably as a consequence of the reduction of serum concentrations of cholesterol and triglycerides. Increased expression of aortic SIRT1 and PGC-1α could play an important role in the observed effects of IFC in rabbits with dyslipidemia. © 2014 American Society for Nutrition.

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.

Aim To evaluate aerobic exercise in migraine and co-existing tension-type headache and neck pain. Methods Consecutively recruited persons with migraine and co-existing tension-type headache and neck pain were randomized into an exercise group or control group. Aerobic exercise consisted of bike/cross-trainer/brisk walking for 45 minutes, three times/week. Controls continued usual daily activities. Pain frequency, intensity, and duration; physical fitness, level of physical activity, well-being and ability to engage in daily activities were assessed at baseline, after treatment and at follow-up. Results Fifty-two persons completed the study. Significant between-group improvements for the exercise group were found for physical fitness, level of physical activity, migraine burden and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Within the exercise group, significant reduction was found for migraine frequency, pain intensity and duration, neck pain intensity, and burden of migraine; an increase in physical fitness and well-being. Conclusions Exercise significantly reduced the burden of migraine and the ability to engage in physical activity because of reduced impact of tension-type headache and neck pain. Exercise also reduced migraine frequency, pain intensity and duration, although this was not significant compared to controls. These results emphasize the importance of regular aerobic exercise for reduction of migraine burden.

Objective To ascertain whether a parent education program based on Satter’s division of responsibility in feeding children (DOR) is effective in enhancing parent/child feeding interactions for children with an overweight/obese parent. The primary hypothesis was that the intervention would decrease parental pressure to eat. Methods Sixty-two families with a child aged 2–4 years with at least one overweight/obese parent were randomly allocated using a cluster design to either the DOR intervention or a control group. The control group focused on increasing family consumption of healthy foods and activity levels, and enhancing child sleep duration. The primary outcome was parent pressure on their child to eat. Results The DOR intervention was superior to the control group in reducing pressure to eat. Two moderators of pressure to eat were found: disinhibition of eating and hunger. DOR group parents irrespective of disinhibition levels lowered pressure to eat whereas control group parents with low disinhibition increased pressure to eat. There were similar findings for hunger. Gender moderated restrictive feeding with DOR parents lowering restriction more than the control group in girls only. Conclusion The DOR intervention was more effective in reducing parent pressure to eat and food restriction (in girls only) than the control group. PMID:22947882

To observe the changes of intestinal inflammation on PDIA3 gene knockout IBS rats and its effect on immune function. 36 SD rats were randomly divided into four groups: the control group (n = 8); IBS- empty virus group (IBS-GFP, which); IBS-PDIA3 knockout group (n = 12); IBS- the control group (n = 12). After modeling, colon and ileocecal tissue pathology in each group were observed separately. Changes of immune and inflammatory markers were measured. At the same time, ultrastructural changes in each group were observed by electron microscopy. Compared with the IBS control group, inflammation was reduced significantly in IBS-PDIA3 knockout group. IgE, IL-4 and IL-9 and the level of intestinal trypsin type were decreased significantly. Furthermore, mast cell degranulation and PAR 2 receptor reduced significantly. PDIA3 may play an important role in the development of IBS by mediating through immune responses of mucosal abnormalities. However, the mechanism needs to be confirmed in further study.

To establish a rabbit model of silicotic pulmonary fibrosis and to investigate the effect of cordyceps sinensis in this model. Thirty healthy male white rabbits were randomly divided into control group, silicosis model group, and intervention group. The rabbits in silicosis model group and intervention group received endotracheal perfusion of silicon dioxide suspension (120 mg/kg), and the control group was treated with the same volume of saline. All the rabbits were sacrificed 30 days later. The lung coefficient was calculated by comparing the lung weight and body weight; the right lung tissue was stained with hematoxylin-eosin (HE). The content of hydroxyproline in lung tissue was measured by alkaline hydrolysis. The mRNA levels of transforming growth factor beta 1 (TGF-β₁) and mothers against decapentaplegic homolog 7 (Smad7) in rabbit lung sections were determined by real-time PCR. No abnormalities were observed by HE staining in the lung tissues of control group, while fibrosis and silicotic nodules were discovered in the silicosis model group and intervention group. The lung coefficient and the content of hydroxyproline in lung tissue were significantly higher in the silicosis model group than in the control group and intervention group (P < 0.05 or P < 0.01). Compared with the control group, the silicosis model group and intervention group had significantly increased TGF-β₁ mRNA levels but significantly reduced Smad7 mRNA levels (P < 0.02). Compared with the silicosis model group, the intervention group had a significantly reduced TGF-β₁ mRNA level but a significantly increased Smad7 mRNA level (P < 0.05). Cordyceps sinensis is able to reduce the expression of TGF-β₁ mRNA and increase the expression of Smad7 mRNA in lung tissues of rabbits with silicotic pulmonary fibrosis, and thus postpone the progression of fibrosis.

The objective of this study was to assess the efficacy of a newly developed warm-up programme ('11+ Kids') regarding its potential to reduce injuries in children's football. Children's football teams (under 9 years, under 11 years, and under 13 years age groups) from Switzerland, Germany, the Czech Republic and the Netherlands were invited. Clubs were randomised to an intervention group and a control group, and followed for one season. The intervention group replaced their usual warm-up by '11+ Kids', while the control group warmed up as usual. The primary outcome was the overall risk of football-related injuries. Secondary outcomes were the risks of severe and lower extremity injuries. We calculated hazard ratios using extended Cox models, and performed a compliance analysis. In total, 292,749 h of football exposure of 3895 players were recorded. The mean age of players was 10.8 (standard deviation 1.4) years. During the study period, 374 (intervention group = 139; control group = 235) injuries occurred. The overall injury rate in the intervention group was reduced by 48% compared with the control group (hazard ratio 0.52; 95% confidence interval 0.32-0.86). Severe (74% reduction, hazard ratio 0.26; 95% confidence interval 0.10-0.64) and lower extremity injuries (55% reduction, hazard ratio 0.45; 95% confidence interval 0.24-0.84) were also reduced. Injury incidence decreased with increasing compliance. '11+ Kids' is efficacious in reducing injuries in children's football. We observed considerable effects for overall, severe and lower extremity injuries. The programme should be performed at least once per week to profit from an injury preventive effect. However, two sessions per week can be recommended to further increase the protective benefit. ClinicalTrials.gov identifier: NCT02222025.

The purpose of this article is to investigate the effect of Opuntia stricta H (Cactaceae) extract on suppression of hypertrophic scar on ventral surface wounds of rabbit ears. Full thickness skin defection was established in a rabbit ear to simulate hypertrophic scar. Opuntia extract was sprayed on the wounds in the experimental group, and normal saline was used in the control group. After the wounds healed with scar formation, the hypertrophic scar tissue was harvested on days 22, 39, and 54 for histological analysis. The expression of type I and type III collagen and matrix metalloproteinase-1 (MMP-1) were evaluated by immunohistochemistry and real-time quantitative polymerase chain reaction. The results indicated that the scar of the control group is more prominent compared with the opuntia extract group. The expression of type I collagen in the opuntia extract group was lower than the control group, while type III collagen in opuntia extract group gradually increased and exceeded control group. The expression of MMP-1 decreased in the opuntia extract group, while the control group increased over time, but the amount of MMP-1 was much higher than that in the control group on day 22. In conclusion, opuntia extract reduces hypertrophic scar formation by means of type I collagen inhibition, and increasing type III collagen and MMP-1.T he novel application of opuntia extract may lead to innovative and effective antiscarring therapies. © The Author(s) 2015.

To evaluate if wearing unstable shoes reduces low back pain and disability in nurses. A randomized controlled trial. Hospitals and homecare. A total of 20 matched female registered nurses with low back pain. The mean (standard deviation) age was 31 years (5) for the control and 34 years (6) for the intervention group; height was 161 cm (5) and 165 cm (7), respectively. The intervention group received unstable shoes at Week 2 to wear for at least 36 h/week for a month. The Oswestry Low Back Pain Disability Questionnaire and a visual analogue pain scale. The mean (standard deviation) pain level was 6 (1) at baseline vs. 6 (2) at Week 6 for the control group, and 5 (1) vs. 1 (1) for the intervention group. The mean (standard deviation) disability level was 31% (9) at baseline vs. 28% (7) at Week 6 for the control, and 27% (12) vs. 13% (5) for the intervention group. There were no significant changes over time on pain or disability levels for the control group. The intervention group reported lower levels of pain on Weeks 4 (mean difference ⩾-1.4, p ⩽ 0.009) and 6 (mean difference ⩾-3.1, p < 0.001). Disability levels were also lower on Weeks 4 (mean difference = -4.5%, p NS) and 6 (mean difference = -14.1%, p = 0.020). Wearing unstable shoes reduced low back pain and disability in nurses and might be helpful as part of the back pain rehabilitation process. © The Author(s) 2015.

Epidural scar formation after laminectomy impede surgical outcomes of decompression. Mitomycin C (MMC) has been demonstrated to have significant inhibitory effects on epidural scar. This study was undertaken to develop an effective MMC controlled‑release membrane and to investigate its effects on epidural scar in rat models of laminectomy. A total of 72 rats that underwent laminectomy were divided into three groups. Among them, 24 were treated with mitomycin C‑polylactic acid (MMC-PLA) controlled‑release membrane, 24 with mitomycin C-polyethylene glycol (MMC-PEG) controlled-release membrane, and no treatment was performed for the remaining 24 rats (control group). In the following 4 weeks, magnetic resonance image (MRI), macroscopic observation, histology and hydroxyproline (Hyp) concentration analysis were performed to explore the effects of these three therapies on epidural scar. MRI revealed a significant reduction of epidural fibrosis in MMC-PLA and MMC-PEG treatment groups, compared with the control group. Histological results also showed that collagen deposition was significantly reduced after being treated with MMC-PLA or MMC-PEG membranes. Likewise, Hyp concentrations of the epidural scar tissue in MMC-PLA and MMC-PEG groups were markedly lower than those in the control group. However, regarding the effects on reducing epidural scar, no significant difference was found between the MMC-PLA and MMC-PEG groups. In conclusion, MMC-PLA and MMC-PEG membranes are safe and effective in reducing fibrosis. Thus, MMC-controlled-release membranes promises to be a potential therapeutic in preventing epidural scar formation after laminectomy.

Formation of a xerogel in reduced gravity using the acid catalysed silica sol-gel reaction

NASA Astrophysics Data System (ADS)

Pienaar, Christine L.; Steinberg, Theodore A.

2006-01-01

An acid catalysed silica sol-gel reaction was used to create a xerogel in reduced gravity. Samples were formed in a special apparatus which utilised vacuum and heating to speed up the gelation process. Testing was conducted aboard NASA's KC-135 aircraft which flies a parabolic trajectory, producing a series of 25 second reduced gravity periods. The samples formed in reduced gravity were compared against a control sample formed in normal gravity. 29Si NMR and nitrogen adsorption/desorption techniques yielded information on the molecular and physical structure of the xerogels. The microstructure of the reduced gravity samples contained more Q 4 groups and less Q 3 and Q2 groups than the control sample. The pore size of the reduced gravity samples was also larger than the control sample. This indicated that in a reduced gravity environment, where convection is lessened due to the removal of buoyancy forces, the microstructure formed through cyclisation reactions rather than bimolecularisation reactions. The latter requires the movement of molecules for reactions to occur whereas cyclisation only requires a favourable configuration. Q 4 groups are stabilised when contained in a ring structure and are unlikely to undergo repolymerisation. Thus reduced gravity favoured the formation of a xerogel through cyclisation, producing a structure with more highly coordinated Q groups. The xerogel formed in normal gravity contained both chain and ring structures as bimolecularisation reactions were able to effectively compete with cyclisation.

Aim of this study was to investigate the effects of sleep deprivation on salivary factors in rats. Animals were randomly assigned into three groups of 6 animals each as control, total sleep deprivation (TSD) and partial sleep deprivation (PSD) groups. The multiple platform method was used to induce partial and total sleep deprivation for 7days. On the 8th day, stimulated saliva samples were collected for the analysis of salivary lag time, flow rate, salivary amylase activity, immunoglobulin A secretion rate and corticosterone levels using ELISA and standard kinetic enzyme assay. Data were analyzed using ANOVA with Dunnett T3 post hoc tests. Salivary flow rate reduced significantly in the TSD group compared with the PSD group as well as the control group (p=0.01). The secretion rate of salivary IgA was significantly reduced in the TSD group compared with the control group (p=0.04). Salivary amylase activity was significantly elevated in the TSD group compared with the PSD group as well as control group (p<0.001). However, there were no significant changes in the salivary lag time and levels of corticosterone among the groups. These findings suggest that total sleep deprivation is associated with reduced salivary flow rate and secretion rate of IgA as well as elevated levels of salivary amylase activity in rats. However, sleep recovery of four hours in the PSD group produced ameliorative effects on the impaired functions of salivary glands. Copyright © 2016 Elsevier Ltd. All rights reserved.

Evidence on the effectiveness of ergonomic interventions to reduce mechanical demands and upper-extremity MSDs is scarce in agriculture. We conducted an intervention to reduce mechanical exposures during manual flower cutting through job rotation, education and reduction of force requirements. One-hundred and twenty workers (20 to 60 years old; 89% women) from six companies that cultivate roses participated in this study. Three companies were randomly assigned to control and intervention groups. We studied changes between baseline and follow-up in self-reported effort and upper-extremity postures, kinematics and muscular activity. Most of the observed changes were moderate for both groups. The intervention group showed differential improvements compared to the control group for the maximum wrist radial deviation and forearm pronation, and acceleration of the forearm supination-pronation and elbow flexion-extension; and the muscular activity of the flexor and extensor carpi radialis and the flexor carpi ulnaris. However, we also observed that the maximum ulnar deviation, velocity of the wrist flexion-extension and muscular activity of the extensor carpi ulnaris improved more in the control group. These mixed results may be related to limited time for intervention adjustment, and uncontrolled task changes in the control group. Future research should address these issues and test other solutions.

Total knee arthroplasty (TKA) accompanies the risk of bleeding and need for transfusion. There are several methods to reduce postoperative blood loss and blood transfusion. One such method is using tranexamic acid during TKA. The purpose of this study was to confirm whether tranexamic acid reduces postoperative blood loss and blood transfusion after TKA. A total of 100 TKA patients were included in the study. The tranexamic acid group consisted of 50 patients who received an intravenous injection of tranexamic acid. The control included 50 patients who received a placebo injection. The amounts of drainage, postoperative hemoglobin, and transfusion were compared between the groups. The mean amount of drainage was lower in the tranexamic acid group (580.6±355.0 mL) than the control group (886.0±375.5 mL). There was a reduction in the transfusion rate in the tranexamic acid group (48%) compared with the control group (64%). The hemoglobin level was higher in the tranexamic acid group than in the control group at 24 hours postoperatively. The mean units of transfusion were smaller in the tranexamic acid group (0.76 units) than in the control group (1.28 units). Our data suggest that intravenous injection of tranexamic acid decreases the total blood loss and transfusion after TKA.

Patients with decompensated cirrhosis have significantly reduced survival without liver transplantation. Granulocyte colony-stimulating factor (G-CSF) has been shown to increase survival in patients with acute-on-chronic liver failure, and erythropoietin promoted hepatic regeneration in animal studies. We performed a double-blind, randomized, placebo-controlled trial to determine whether co-administration of these growth factors improved outcomes for patients with advanced cirrhosis. In a prospective study, consecutive patients with decompensated cirrhosis seen at the Institute of Liver and Biliary Sciences, New Delhi (from May 2011 through June 2012) were randomly assigned to groups given subcutaneous G-CSF (5 μg/kg/d) for 5 days and then every third day (12 total doses), along with subcutaneous darbopoietin α(40 mcg/wk) for 4 weeks (GDP group, n = 29), or only placebos (control group, n = 26). All patients also received standard medical therapy and were followed for 12 months. Histology was performed on liver biopsies. The primary end point was survival at 12 months. Baseline characteristics of patients were comparable; alcohol intake was the most common etiology of cirrhosis. A higher proportion of patients in the GDP group than controls survived until 12 months (68.6% vs 26.9%; P = .003). At 12 months, Child-Turcotte Pugh scores were reduced by 48.6% in the GDP group and 39.1% in the control group, from baseline (P = .001); Model for End Stage Liver Disease scores were reduced by 40.4% and 33%, respectively (P = .03). The need for large-volume paracentesis was significantly reduced in GDP group, compared with controls (P < .05). A lower proportion of patients in the GDP group developed septic shock (6.9%) during follow-up compared with controls (38.5%; P = .005). No major adverse events were observed in either group. In a single-center randomized trial, a significantly larger proportion of patients with decompensated cirrhosis given a combination of G-CSF and darbopoietin α survived for 12 months more than patients given only placebo. The combination therapy also reduced liver severity scores and sepsis to a greater extent than placebo. Clinicaltrials.gov ID: NCT01384565. Copyright © 2015 AGA Institute. Published by Elsevier Inc.

Persons with mild dementia experience multiple losses and manifest depressive symptoms. This research study aimed to evaluate the effectiveness of a support group led by a social worker for Chinese persons with mild dementia. Participants were randomly assigned to either a ten-session support group or a control group. Standardized assessment tools were used for data collection at pretreatment and post-treatment periods by a research assistant who was kept blind to the group assignment of the participants. Upon completion of the study, 20 treatment group participants and 16 control group participants completed all assessments. At baseline, the treatment and control groups did not show any significant difference on all demographic variables, as well as on all baseline measures; over one-half (59%) of all the participants reported having depression, as assessed by a Chinese Geriatric Depression Scale score ≥8. After completing the support group, the depressive mood of the treatment group participants reduced from 8.83 (standard deviation =2.48) to 7.35 (standard deviation =2.18), which was significant (Wilcoxon signed-rank test; P=0.017, P<0.05), while the control group's participants did not show any significant change. This present study supports the efficacy and effectiveness of the support group for persons with mild dementia in Chinese society. In particular, this present study shows that a support group can reduce depressive symptoms for participants.

To investigate the effectiveness and cost of an 18-month multi-disciplinary Comprehensive Fragility Fracture Management Program (CFFMP) for fragility hip fracture patients. Prospective cohort study. Elderly patients with hip fracture were recruited at their first postoperative follow-up in 2 district hospitals. The intervention group comprised patients from the hospital undergoing CFFMP, and the control group comprised patients from another hospital undergoing conventional care. CFFMP provided geri-orthopaedic co-management, physician consultations, group-exercise and vibration-therapy. Timed-up-and-go test (TUG), Elderly Mobility Scale (EMS), Berg Balance Scale (BBS) and fall risk screening (FS) were used to assess functional performance. Incidences of falls and secondary fractures, the cost of the programme and related healthcare resources were recorded. A total of 76 patients were included in the intervention group (mean age 77.9 years ((standard deviation; SD) 6.1) ) and 77 in the control group (79.9 (SD 7.2)), respectively. The re-fracture rate in the control group (10.39%) was significantly higher than in the intervention group (1.32%) (p = 0.034). The intervention group improved significantly in TUG, EMS and FS after a 1-year programme. The overall healthcare costs per patient in the intervention and control groups were US$22,450 and US$25,313, respectively. Multi-disciplinary CFFMP is effective, with reduced overall cost, reduced length of hospital stay and reduced secondary fracture rate. The rehabilitation community service favours rehabilitation and improved quality of life of hip fracture patients.

To study the leptin resistance mechanism of Xiaoyan Decoction (XD) in lung cancer cachexia (LCC) rats. An LCC rat model was established. Totally 40 rats were randomly divided into the normal control group, the LCC model group, the XD group, and the positive control group, 10 in each group. After LCC model was set up, rats in the LCC model group were administered with normal saline, 2 mL each time. Rats in the XD group were administered with XD at the daily dose of 2 mL. Those in the positive control group were administered with Medroxyprogesterone Acetate suspension (20 mg/kg) by gastrogavage at the daily dose of 2 mL. All medication lasted for 14 days. The general condition and tumor growth were observed. Serum levels of leptin and leptin receptor in the hypothalamus were detected using enzyme-linked immunosorbent assay. Contents of neuropeptide Y (NPY) and anorexia for genomic POMC were detected using real-time PCR technique. Serum leptin levels were lower in the LCC model group than in the normal control group with statistical significance (P < 0.05). Compared with the LCC model groups, serum leptin levels significantly increased in the XD group (P < 0.01). Leptin receptor levels in the hypothalamus increased significantly in the LCC model group (P < 0.01). Increased receptor levels in the LCC model group indicated that either XD or Medroxyprogesterone Acetate could effectively reduce levels of leptin receptor with statistical significance (P < 0.01). There was also statistical difference between the XD group and the positive control group (P < 0.05). Contents of NPY was higher in the LCC model group than in the other groups with statistical difference (P < 0.05). There was no statistical difference in NPY between the normal control group and the rest 2 treatment groups (P > 0.05). There was statistical difference in POMC between the normal control group and the LCC model group (P < 0.05). POMC could be decreased in the XD group and the positive control group with statistical significance (P < 0.05), and it was more obviously decreased in the XD group (P < 0.05). Leptin resistance existed in LCC rats. XD could increase serum leptin levels and reduce leptin receptor levels in the hypothalamus. LCC could be improved by elevating NPY contents in the hypothalamus and reducing POMC contents, promoting the appetite, and increasing food intake from the periphery pathway and the central pathway.

Randomized skin flaps are extensively used in plastic surgery, but the possibility of necrosis has challenged their use. Several studies have been conducted aiming to find ways to reduce the occurrence of necrosis. We evaluated the effects of pentoxifylline (PTX) and hyaluronidase (HLD), each alone or combined, on randomized rat skin flaps. Fifty male Wistar rats were divided into five groups of 10 animals each: control I, control II, PTX, HLD, PTX-HLD. Substances were administered from the first to the 14th postoperative day. The necrotic area was measured on the seventh and 14th postoperative day; the animals were killed on the 14th day, when samples were collected for histologic and immunohistochemical examination. On the seventh day, percentage of the necrotic area was significantly reduced in PTX, HLD, and PTX-HLD animals compared with control groups. On 14th day, percentage of the necrotic area in PTX, HDL, and PTX-HLD groups was also significantly reduced compared with control groups. PTX and PTX-HLD showed a significant reduction in dermis cellularity, V V of macrophages, and myofibroblasts compared with control groups; PTX showed a significant enhancement of L V of blood vessels compared with all other groups. The use of each substance alone or combined increased flap viability compared with control groups. On the seventh day, PTX exhibited lower viability than HLD, whereas on the 14th day there was no difference between treated groups. PTX alone enhanced the L V of blood vessels, whereas PTX-HLD did not. However, PTX-HLD was more effective in decreasing the dermis cellularity and macrophage V V than HLD alone.

The increasing number of motorcyclists in Nigeria has led to a rise in poor road safety practices leading to increased rate of accidents. This study was conducted to implement and evaluate the effect of safety education on riding habits of motorcyclists in Uyo, Nigeria. The intervention study was conducted among commercial motorcyclists in Uyo with controls from another town in Akwa Ibom State. Baseline information was collected from both groups on their riding habits. Motorcyclists in Uyo were educated on appropriate road safety practices. Data was collected from both groups three months later and analysed using the Statistical Package for Social Sciences version 11. A total of 200 respondents participated in the study, 100 per group. At 3 months post-intervention, those riding when tired reduced in the intervention group from 69% at baseline to 42% (p < 0.05), while in the control group it increased from 74% to 79%. Furthermore, those who rested during riding hours increased from 30% at baseline to 93% (p < 0.05) in the intervention group, while it reduced from 40% to 36% in the control group. Those riding within speed limit in the intervention group increased from 37.5% at baseline to 56.6% (p < 0.05), while in the control group, it remained the same. Use of psycho-active substances reduced in the intervention group, though the changes were not statistically significant at p < 0.05. Safety education improved many riding habits of motorcyclists in the intervention group. Road safety education is recommended for all motorcyclists to ensure safer road use.

The clinical impact of intraoperative autofluorescence-based identification of parathyroids using a near-infrared camera remains unknown. In a before and after controlled study, we compared all patients who underwent total thyroidectomy by the same surgeon during Period 1 (January 2015 to January 2016) without near-infrared (near-infrared- group) and those operated on during Period 2 (February 2016 to September 2016) using a near-infrared camera (near-infrared+ group). In parallel, we also compared all patients who underwent surgery without near-infrared during those same periods by another surgeon in the same unit (control groups). Main outcomes included postoperative hypocalcemia, parathyroid identification, autotransplantation, and inadvertent resection. The near-infrared+ group displayed significantly lower postoperative hypocalcemia rates (5.2%) than the near-infrared- group (20.9%; P < .001). Compared with the near-infrared- patients, the near-infrared+ group exhibited an increased mean number of identified parathyroids and reduced parathyroid autotransplantation rates, although no difference was observed in inadvertent resection rates. Parathyroids were identified via near-infrared before they were visualized by the surgeon in 68% patients. In the control groups, parathyroid identification improved significantly from Period 1 to Period 2, although autotransplantation, inadvertent resection and postoperative hypocalcemia rates did not differ. Near-infrared use during total thyroidectomy significantly reduced postoperative hypocalcemia, improved parathyroid identification and reduced their autotransplantation rate.

2017-12-01

One of the local factors contributing to the formation of heterotopic ossification includes bone debris generated during the surgery. This risk can be partially nullified by use of saline wash. Our research aim was to ascertain if extensive intraoperative lavage can reduce the incidence and severity of heterotopic ossification in primary total hip arthroplasty. A retrospective case control radiological study of 145 patients (175 hip replacements). The control group received minimal intra-operative lavage (<1,000 mL); consisted of 90 primary hip replacements. The index group received extensive saline lavage (>3,000 mL), and included 85 primary hip replacements. Brooker classification was used to grade radiographs at one year for development of heterotopic ossification. Sixty-six patients in control group had heterotopic ossification, with six showing a significant grade (grade 3 or 4). Thirty-five patients in the index group had heterotopic ossification with no incidence of severe grade. Majority patients in the index group showed a predominantly grade 1 heterotopic ossification; 28 out of 35, as compared to 37 out of 66 in control group. There was a statistically significant difference in the incidence ( P <0.05) as well as severity of heterotopic ossification between the groups ( P <0.05). We conclude that use of extensive lavage during total hip replacement reduces the incidence as well as severity of heterotopic ossification.

This study assessed the efficacy of a school-based healthy lifestyle intervention (Sport for LIFE) for increasing physical activity, decreasing sedentary behaviour, reducing screen time behaviour, encouraging healthy attitudes and behaviour to nutrition, and reducing body mass index (BMI) in 8-9-year-old primary school children from lower socioeconomic backgrounds in Northern Ireland. A non-randomised controlled trial of 416 children from 24 schools took part. Schools were randomly assigned to one of two groups, an intervention or control group with 12 schools in each group. The intervention group received a 12-week school-based programme based on social cognitive theory. At baseline and follow-up, groups completed questionnaires assessing physical activity, screen time behaviour and dietary patterns. On each occasion anthropometric assessments of height and weight were taken. Physical activity and sedentary behaviour were measured by accelerometry. Significant effects were observed for vigorous, moderate and light activity for the intervention group at follow-up. Sedentary behaviour was significantly reduced for the intervention group but not for the control group. No significant effects of the intervention on BMI, screen time behaviour or attitudes to nutrition, with the exception of non-core foods, were shown. The programme was effective in increasing physical activity and reducing sedentary behaviour, however no significant changes in screen time behaviour and attitude to nutrition, with the exception of non-core foods, were observed. Future research ideas are offered for tackling low levels of physical activity in children.

The objective of this study is to evaluate whether therapeutic hypothermia reduces the incidence of acute kidney injury (AKI) among term neonates perinatal asphyxia. This randomized controlled trial conducted in a tertiary care teaching hospital, south India included 120 term neonates with perinatal asphyxia who were randomized to receive either therapeutic hypothermia or standard supportive care. Renal parameters of neonates in both the groups were monitored and AKI was ascertained as per Acute Kidney Injury Network criteria. The incidence of AKI was less in therapeutic hypothermia group compared to standard treatment group (32% versus 60%, p < 0.05). The incidence of Stages 1, 2, and 3 AKI was 22%, 5%, and 5% in therapeutic hypothermia group compared with 52%, 5%, and 3%, respectively, in the standard treatment group. The mortality was less in therapeutic hypothermia group compared with the standard treatment group (26% versus 50%, p < 0.05). Therapeutic hypothermia reduces the incidence and severity of AKI among term neonates with perinatal asphyxia.

When undergo ambulatory surgical operations, the majority of patients experience high level of anxiety. Different experimental studies have shown that distraction techniques are effective in reducing pain and related anxiety. Since Virtual reality (VR) has been demonstrated a good distraction technique, it has been repeatedly used in hospital contexts for reducing pain in burned patients, but it has never been used during surgical operations. With the present randomized controlled study we intended to verify the effectiveness of VR in reducing anxiety in patients undergoing ambulatory operations under local or regional anaesthesia. In particular, we measured the degree to which anxiety associated with surgical intervention was reduced by distracting patients with immersive VR provided through a cell phone connected to an HMD compared to a no-distraction control condition. A significant reduction of anxiety was obtained after 45 minutes of operation in the VR group, but not in the control group and, after 90 minutes, the reduction was larger in the experimental group than in other one. In conclusion, this study presents an innovative promising technique to reduce anxiety during surgical interventions, even if more studies are necessary to investigate its effectiveness in other kinds of operations and in larger numbers of patients.

A group of pathological gamblers and a group of problem gamblers (i.e., gamblers at risk of becoming pathological) were compared to healthy controls on their risk-taking propensity after prior losses. Each participant played both the Balloon Analogue Risk Taking task (BART) and a modified version of the same task, where individuals face five repeated predetermined early losses at the onset of the game. No significant difference in risk-taking was found between groups on the standard BART task, while significant differences emerged when comparing behaviors in the two tasks: both pathological gamblers and controls reduced their risk-taking tendency after prior losses in the modified BART compared to the standard BART, whereas problem gamblers showed no reduction in risk-taking after prior losses. We interpret these results as a sign of a reduced sensitivity to negative feedback in problem gamblers which might contribute to explain their loss-chasing tendency.

To determine the efficacy of topical 0.3% ciprofloxacin in reducing conjunctival biota in patients undergoing cataract surgery. Experimental, prospective, randomized, controlled and single-blind study. Forty-six eyes of 46 patients were randomized into 2 groups, the study group (n=23) received topical 0.3% ciprofloxacin one day before surgery for six times, and on the day of the surgery one drop every 15minutes starting one hour before surgery until 3 doses were completed. The control group (n=23) did not receive any antibiotics. For both groups for the surgical field 10% povidone-iodine was applied. Samples from the conjunctiva were taken at four different times and then cultured on solid media (chocolate agar, blood agar) and enrichment broth (thioglycolate). The aqueous humor samples were also cultured in thioglycolate. The presence of bacteria was identified quantitatively and qualitatively, and the frequency of contamination was measured by considering the presence of bacteria in liquid and solid culture media. The number of colony forming units (CFU) was counted in the solid culture medium. Positive cultures were obtained in 82.6% and 78.2% of the patients in the study and control groups, respectively, before the administration of 0.3% ciprofloxacin. The administration of 0.3% ciprofloxacin significantly reduced the CFU compared to the control group (P<.05). Immediately after the use of povidone-iodine, the proportion of patients with a positive culture decreased to 21.7% in the study group, and 8.7% in the control group. At the end of the surgery, this percentage was 26% and 30.4%, respectively. The most common isolated pathogen was negative-coagulase Staphylococcus (66.7%). The administration of 0.3% ciprofloxacin reduces conjunctival bacterial load in the preoperative period. However, it was unable to eradicate the bacteria completely. The administration of povidone-iodine reduced conjunctival biota in 50%-70% of patients undergoing cataract surgery. Copyright © 2012 Sociedad Española de Oftalmología. Published by Elsevier Espana.

Musicians are a prone group to suffer from working-related musculoskeletal disorder (WRMD). Conventional solutions to control musculoskeletal pain include pharmacological treatment and rehabilitation programs but their efficiency is sometimes disappointing. The aim of this research is to study the immediate effects of Tuina techniques on WRMD of professional orchestra musicians from the north of Portugal. We performed a prospective, controlled, single-blinded, randomized study. Professional orchestra musicians with a diagnosis of WRMD were randomly distributed into the experimental group (n=39) and the control group (n=30). During an individual interview, Chinese diagnosis took place and treatment points were chosen. Real acupoints were treated by Tuina techniques into the experimental group and non-specific skin points were treated into the control group. Pain was measured by verbal numerical scale before and immediately after intervention. After one treatment session, pain was reduced in 91.8% of the cases for the experimental group and 7.9% for the control group. Although results showed that Tuina techniques are effectively reducing WRMD in professional orchestra musicians of the north of Portugal, further investigations with stronger measurements, double-blinding designs and bigger simple sizes are needed.

To find out whether a nurse-delivered educational package can reduce chronic oral non-steroidal anti-inflammatory drug (NSAID) usage in general practice. A prospective randomized controlled trial with assessment of economic cost/benefits was carried out in five general practices in Nottinghamshire with computerized prescribing systems, representing a mix of rural/urban and fundholding/non-fundholding practices. Patients suffering from non-malignant, non-inflammatory musculoskeletal pain received repeat prescriptions for oral NSAIDs. Two hundred and twenty-two patients were randomized to a control group (simple advice regarding NSAID use) or an intervention group (asked to withdraw their NSAIDs and employ appropriate alternative drug and non-drug therapies). All advice was supported by patient literature and delivered by a nurse practitioner trained in musculoskeletal assessment. The primary outcome measure was change in NSAID use 6 months after the intervention. Secondary outcome measures were changes in health and quality of life (SF-36 and EQ-5D questionnaires) and drug, health service and patient costs. An extra 28% of patients in the intervention group either stopped taking oral NSAIDs or reduced dosage by > or =50% at 6 months compared with controls. There was no detrimental effect on health and well-being. Oral NSAID prescription costs were significantly lowered in the intervention group but not in the control group. A non-significant increase in total drug prescription costs occurred in both groups. Nurse-based intervention can reduce chronic NSAID usage and costs in primary care and would be cost-effective if maintained in the long term. This intervention package would be readily applicable in primary care.

The aim of this study was to investigate if teaching patients about positioning before radiotherapy treatment would (a) reduce the residual rotational set-up errors, (b) reduce the number of repositionings and (c) improve patients' sense of control by increasing self-efficacy and reducing distress. Patients were randomized to either standard care (control group) or standard care and a teaching session combining visual aids and practical exercises (intervention group). Daily images from the treatment sessions were evaluated off-line. Both groups filled in a questionnaire before and at the end of the treatment course on various aspects of cooperation with the staff regarding positioning. Comparisons of residual rotational set-up errors showed an improvement in the intervention group compared to the control group. No significant differences were found in number of repositionings, self-efficacy or distress. Results show that it is possible to teach patients about positioning and thereby improve precision in positioning. Teaching patients about positioning did not seem to affect self-efficacy or distress scores at baseline and at the end of the treatment course.

In patients with gastroesophageal reflux disease (GERD) and excessive belching, most belches are supragastric, and can induce reflux episodes and worsen GERD. Supragastric belching (SGB) might be reduced with diaphragmatic breathing exercises. We investigated whether diaphragmatic breathing therapy is effective in reducing belching and proton pump inhibitor (PPI)-refractory gastroesophageal reflux symptoms. We performed a prospective study of 36 consecutive patients with GERD refractory to PPI therapy and a belching visual analogue scale (VAS) score of 6 or more, seen at a gastroenterology clinic at a tertiary hospital in Singapore from April 2015 through October 2016. Patients underwent high-resolution manometry and 24-hour pH-impedance studies while they were off PPIs. Fifteen patients were placed on a standardized diaphragmatic breathing exercise protocol (treatment group) and completed questionnaires at baseline, after diaphragmatic breathing therapy, and 4 months after the therapy ended. Twenty-one patients were placed on a waitlist (control subjects), completed the same questionnaires with an additional questionnaire after their waitlist period, and eventually received diaphragmatic breathing therapy. The primary outcome was reduction in belching VAS by 50% or more after treatment. Secondary outcomes included GERD symptoms (evaluated using the reflux disease questionnaire) and quality of life (QoL) scores, determined from the Reflux-Qual Short Form and EuroQoL-VAS. Nine of the 15 patients in the treatment group (60%) and none of the 21 control subjects achieved the primary outcome (P < .001). In the treatment group, the mean belching VAS score decreased from 7.1 ± 1.5 at baseline to 3.5 ± 2.0 after diaphragmatic breathing therapy; in the control group, the mean VAS score was 7.6 ± 1.1 at baseline and 7.4 ± 1.3 after the waitlist period. Eighty percent of patients in the treatment group significantly reduced belching frequency compared with 19% in control subjects (P = .001). Treatment significantly reduced symptoms of GERD (the mean reflux disease questionnaire score decreased by 12.2 in the treatment group and 3.1 in the control group; P = .01). The treatment significantly increased QoL scores (the mean Reflux-Qual Short Form score increased by 15.4 in the treatment group and 5.2 in the control group; P = .04) and mean EuroQoL-VAS scores (15.7 increase in treatment group and 2.4 decrease in the control group). These changes were sustained at 4 months after treatment. In the end, 20 of the 36 patients who received diaphragmatic breathing therapy (55.6%), all with excessive SGB, achieved the primary outcome. In a prospective study, we found a standardized protocol for diaphragmatic breathing to reduce belching and PPI-refractory gastroesophageal reflux symptoms, and increase QoL in patients with PPI-refractory GERD with belching-especially those with excessive SGB.

Nonalcoholic fatty liver disease (NAFLD) is a prevalent risk factor for chronic liver disease and cardiovascular disease. To compare the effects of moderate and vigorous exercise on intrahepatic triglyceride content and metabolic risk factors among patients with NAFLD. In this randomized clinical trial, participants with central obesity and NAFLD were recruited from community-based screening in Xiamen, China, from December 1, 2011, through December 25, 2013. Data analysis was performed from August 28, 2015, through December 15, 2015. Participants were randomly assigned to vigorous-moderate exercise (jogging 150 minutes per week at 65%-80% of maximum heart rate for 6 months and brisk walking 150 minutes per week at 45%-55% of maximum heart rate for another 6 months), moderate exercise (brisk walking 150 minutes per week for 12 months), or no exercise. Primary outcome, change in intrahepatic triglyceride content measured by proton magnetic resonance spectroscopy at 6 and 12 months; secondary outcomes, changes in body weight, waist circumference, body fat, and metabolic risk factors. A total of 220 individuals (mean [SD] age, 53.9 [7.1] years; 149 woman [67.7%]) were randomly assigned to control (n = 74), moderate exercise (n = 73), and vigorous-moderate exercise (n = 73) groups. Of them, 211 (95.9%) completed the 6-month follow-up visit; 208 (94.5%) completed the 12-month follow-up visit. Intrahepatic triglyceride content was reduced by 5.0% (95% CI, -7.2% to 2.8%; P < .001) in the vigorous-moderate exercise group and 4.2% (95% CI, -6.3% to -2.0%; P < .001) in the moderate exercise group compared with the control group at the 6-month assessment. It was reduced by 3.9% (95% CI, -6.0% to -1.7%; P < .001) in the vigorous-moderate exercise group and 3.5% (95% CI, -5.6% to -1.3%; P = .002) in the moderate exercise group compared with the control group at the 12-month assessment. Changes in intrahepatic triglyceride content were not significantly different between vigorous-moderate and moderate exercise at the 6- or 12-month assessment. Body weight, waist circumference, and blood pressure were significantly reduced in the vigorous-moderate exercise group compared with the moderate exercise and control groups at the 6-month assessment and in the vigorous-moderate and moderate exercise groups compared with the control group at the 12-month assessment. In addition, body fat was significantly reduced in the vigorous-moderate exercise group compared with the moderate exercise and control groups at the 12-month assessment. After adjusting for weight loss, the net changes in intrahepatic triglyceride content were diminished and became nonsignificant between the exercise and control groups (except for the moderate exercise group at the 6-month assessment). Vigorous and moderate exercise were equally effective in reducing intrahepatic triglyceride content; the effect appeared to be largely mediated by weight loss. clinicaltrials.gov Identifier: NCT01418027.

This paper reports a study to determine the effectiveness of autogenic training in reducing anxiety in nursing students. Nursing is stressful, and nursing students also have the additional pressures and uncertainties shared with all academic students. Autogenic training is a relaxation technique consisting of six mental exercises and is aimed at relieving tension, anger and stress. Meta-analysis has found large effect sizes for autogenic trainings intervention comparisons, medium effect sizes against control groups, and no effects when compared with other psychological therapies. A controlled trial with 50 nursing students found that the number of certified days off sick was reduced by autogenic training compared with no treatment, and a second trial with only 18 students reported greater improvement in Trait Anxiety, but not State Anxiety, compared with untreated controls. A randomized controlled trial with three parallel arms was completed in 1998 with 93 nursing students aged 19-49 years. The setting was a university college in the United Kingdom. The treatment group received eight weekly sessions of autogenic training, the attention control group received eight weekly sessions of laughter therapy, and the time control group received no intervention. The outcome measures were the State-Trait Anxiety Inventory, the Maslach Burnout Inventory, blood pressure and pulse rate completed at baseline, 2 months (end of treatment), and 5, 8, and 11 months from randomization. There was a statistically significantly greater reduction of State (P<0.001) and Trait (P<0.001) Anxiety in the autogenic training group than in both other groups immediately after treatment. There were no differences between the groups for the Maslach Burnout Inventory. The autogenic training group also showed statistically significantly greater reduction immediately after treatment in systolic (P<0.01) and diastolic (P<0.05) blood pressure, and pulse rate (P<0.002), than the other two groups. CONCLUSION. Autogenic training has at least a short-term effect in alleviating stress in nursing students.

Randomized, controlled trial. To evaluate a four-session self-management group intervention for patients with pain in primary care, led by trained lay persons with back pain. The intervention was designed to reduce patient worries, encourage self-care, and reduce activity limitations. Randomized trials of educational interventions suggest that activating interventions may improve back pain outcomes. Expert opinion increasingly regards effective self-management of back pain as important in achieving good outcomes. In this study, an educational intervention designed to activate patients and support effective self-management was evaluated. Six to 8 weeks after a primary care visit for back pain, patients were invited to participate in an educational program to improve back pain self-management. Those showing interest by returning a brief questionnaire became eligible for the study. Participants (n = 255) randomly were assigned to either a self-management group intervention or to a usual care control group. The effect of the intervention, relative to usual care, was assessed 3, 6, and 12 months after randomization, controlling for baseline values. The intervention consisted of a four-session group applying problem-solving techniques to back pain self-management, supplemented by educational materials (book and videos) supporting active management of back pain. The groups were led by lay persons trained to implement a fully structured group protocol. The control group received usual care, supplemented by a book on back pain care. Participants randomly assigned to the self-management groups reported significantly less worry about back pain and expressed more confidence in self-care. Roland Disability Questionnaire Scores were significantly lower among participants in the self-management groups relative to the usual care controls at 6 months (P = 0.007), and this difference was sustained at 12 months at borderline significance levels (P = 0.09). Among self-management group participants, 48% showed a 50% or greater reduction in Roland Disability Questionnaire Score at 6 months, compared with 33% among the usual care controls. Self-management groups led by trained lay persons following a structured protocol were more effective than usual care in reducing worries, producing positive attitudes toward self-care, and reducing activity limitations among patients with back pain in primary care.

Reduced toxicant prototype (RTP) cigarettes with substantially reduced levels of tobacco smoke toxicants have been developed. Evaluation of these prototype cigarettes included measurement of biomarkers of exposure (BoE) to toxicants in smokers switched from conventional cigarettes to the RTPs. A 6-week single-blinded randomised controlled study with occasional clinical confinement was conducted ( ISRCTN7215735). All smoking subjects smoked a conventional cigarette for 2-weeks. Control groups continued to smoke the conventional cigarette while test groups switched to one of three RTP designs. Clinical confinement and additional assessments were performed for all smoking groups after 2 and 4-weeks. A non-smoker group provided background levels of BoE. On average, smokers switched to RTPs with reduced machine yields of toxicants had reduced levels of corresponding BoEs. For vapour phase toxicants such as acrolein and 1,3-butadiene reductions of ⩾70% were observed both in smoke chemistry and BoEs. Reductions in particulate phase toxicants such as tobacco-specific nitrosamines, aromatic amines and polyaromatic hydrocarbons depended upon the technologies used, but were in some cases ⩾80% although some increases in other particulate phase toxicants were observed. However, reductions in BoEs demonstrate that it is possible to produce prototype cigarettes that reduce exposure to toxicants in short-term use. Copyright © 2013 Elsevier Inc. All rights reserved.

The impact of stereotype threat and self-efficacy beliefs on neuropsychological test performance in a clinical traumatic brain injury (TBI) population was investigated. A total of 42 individuals with mild-to-moderate TBI and 42 (age-, gender-, educationally matched) healthy adults were recruited. The study consisted of a 2 (Type of injury: control, TBI) × 2 (Threat Condition: reduced threat, heightened threat) between-participants design. The purpose of the reduced threat condition was to reduce negative stereotyped beliefs regarding cognitive effects of TBI and to emphasize personal control over cognition. The heightened threat condition consisted of an opposing view. Main effects included greater anxiety, motivation, and dejection but reduced memory self-efficacy for head-injured-groups, compared to control groups. On neuropsychological testing, the TBI-heightened-threat-group displayed lower scores on Initial Encoding (initial recall) and trended toward displaying lower scores on Attention (working memory) compared to the TBI-reduced-threat-group. No effect was found for Delayed Recall measures. Memory self-efficacy mediated the relation between threat condition and neuropsychological performance, indicating a potential mechanism for the threat effect. The findings highlight the impact of stereotype threat and self-referent beliefs on neuropsychological test performance in a clinical TBI population.

Although there are a limited number of studies showing effects of neck stretching exercises following a thyroidectomy in reducing neck discomfort symptoms, no study has specifically dealt with and examined the effect of neck stretching exercises on neck pain and disability. To analyze the effect of neck stretching exercises, following a total thyroidectomy, on reducing neck pain and disability. A randomized controlled trial was conducted. The participants were randomly assigned either to the stretching exercise group (n = 40) or to the control group (n = 40). The stretching exercise group learned the neck stretching exercises immediately after total thyroidectomy. The effects of the stretching exercises on the participants' neck pain and disability, neck sensitivity, pain with neck movements as well as on wound healing, were evaluated at the end of the first week and at 1 month following surgery. When comparing neck pain and disability scale (NPDS) scores, neck sensitivity and pain with neck movement before thyroidectomy, after 1 week and after 1-month time-points, it was found that patients experienced significantly less pain and disability in the stretching exercise group than the control group (p < .001). At the end of the first week, the NPDS scores (mean [SD] = 8.82 [12.23] vs. 30.28 [12.09]), neck sensitivity scores (median [IR] = 0 [.75] vs. 2.00 [4.0]) and pain levels with neck movements (median [IR] = 0 [2.0] vs. 3.5 [5.75]) of the stretching exercise group were significantly lower than those of the control group. However, there was no significant difference between the groups with regard to the scores at the 1-month evaluation (p > .05). Neck stretching exercises done immediately after a total thyroidectomy reduce short-term neck pain and disability symptoms. © 2016 Sigma Theta Tau International.

Remote monitoring (RM) in patients with advanced heart failure and cardiac resynchronization therapy defibrillators (CRT-D) may reduce delays in clinical decisions by transmitting automatic alerts. However, this strategy has never been tested specifically in this patient population, with alerts for lung fluid overload, and in a European setting. The main objective of Phase 1 (presented here) is to evaluate if RM strategy is able to reduce time from device-detected events to clinical decisions. In this multicenter randomized controlled trial, patients with moderate to severe heart failure implanted with CRT-D devices were randomized to a Remote group (with remote follow-up and wireless automatic alerts) or to a Control group (with standard follow-up without alerts). The primary endpoint of Phase 1 was the delay between an alert event and clinical decisions related to the event in the first 154 enrolled patients followed for 1 year. The median delay from device-detected events to clinical decisions was considerably shorter in the Remote group compared to the Control group: 2 (25(th)-75(th) percentile, 1-4) days vs 29 (25(th)-75(th) percentile, 3-51) days respectively, P=.004. In-hospital visits were reduced in the Remote group (2.0 visits/patient/year vs 3.2 visits/patient/year in the Control group, 37.5% relative reduction, P<.001). Automatic alerts were successfully transmitted in 93% of events occurring outside the hospital in the Remote group. The annual rate of all-cause hospitalizations per patient did not differ between the two groups (P=.65). RM in CRT-D patients with advanced heart failure allows physicians to promptly react to clinically relevant automatic alerts and significantly reduces the burden of in-hospital visits.

Anesthesia induction in children is frequently achieved by inhalation of nitrous oxide and sevoflurane. Pediatric anesthesiologists commonly use distraction techniques such as humor or nonprocedural talk to reduce anxiety and facilitate a smooth transition at this critical phase. There is a large body of successful distraction research that explores the use of video and television distraction methods for minor medical and dental procedures, but little research on the use of this method for ambulatory surgery. In this randomized control trial study we examined whether video distraction is effective in reducing the anxiety of children undergoing inhaled induction before ambulatory surgery. Children (control = 47, video = 42) between 2 and 10 years old undergoing ambulatory surgery were randomly assigned to a video distraction or control group. In the video distraction group a video clip of the child's preference was played during induction, and the control group received traditional distraction methods during induction. The modified Yale Preoperative Anxiety Scale was used to assess the children's anxiety before and during the process of receiving inhalation anesthetics. All subjects were similar in their age and anxiety scores before entering the operating rooms. Children in the video distraction group were significantly less anxious at induction and showed a significantly smaller change in anxiety from holding to induction than did children in the control group. Playing video clips during the inhaled induction of children undergoing ambulatory surgery is an effective method of reducing anxiety. Therefore, pediatric anesthesiologists may consider using video distraction as a useful, valid, alternative strategy for achieving a smooth transition to the anesthetized state.

Radical cystectomy, which is performed to treat muscle-invasive bladder tumors, is among the most difficult urological surgical procedures and puts patients at risk of intraoperative blood loss and transfusion. Fluid management via stroke volume variation (SVV) is associated with reduced intraoperative blood loss. Therefore, we evaluated the efficacy and safety of SVV-guided fluid therapy for reducing blood loss and transfusion requirements in patients undergoing radical cystectomy.This study included 48 patients who underwent radical cystectomy, and these patients were randomly allocated to the control group and maintained at <10% SVV (n = 24) or allocated to the trial group and maintained at 10% to 20% SVV (n = 24). The primary endpoints were comparisons of the amounts of intraoperative blood loss and transfused red blood cells (RBCs) between the control and trial groups during radical cystectomy. Intraoperative blood loss was evaluated through the estimated blood loss and estimated red cell mass loss. The secondary endpoints were comparisons of the postoperative outcomes between groups.A total of 46 patients were included in the final analysis: 23 patients in the control group and 23 patients in the trial group. The SVV values in the trial group were significantly higher than in the control group. Estimated blood loss, estimated red cell mass loss, and RBC transfusion requirements in the trial group were significantly lower than in the control group (734.3 ± 321.5 mL vs 1096.5 ± 623.9 mL, P = 0.019; 274.1 ± 207.8 mL vs 553.1 ± 298.7 mL, P <0.001; 0.5 ± 0.8 units vs 1.9 ± 2.2 units, P = 0.005). There were no significant differences in postoperative outcomes between the two groups.SVV-guided fluid therapy (SVV maintained at 10%-20%) can reduce blood loss and transfusion requirements in patients undergoing radical cystectomy without resulting in adverse outcomes. These findings provide useful information for optimal fluid management during radical cystectomy.

Chronic low back pain (CLBP) in older adults may be disabling and therapeutically challenging, largely because of the inefficacy and/or morbidity associated with traditional pain treatment. We conducted a randomized controlled trial in 200 men and women ≥ age 65 with CLBP to evaluate the efficacy of percutaneous electrical nerve stimulation (PENS) with and without general conditioning and aerobic exercise (GCAE), for reducing pain and improving physical function. Participants were randomized to receive 1) PENS, 2) control-PENS (brief electrical stimulation to control for treatment expectancy), 3) PENS + GCAE, or 4) control-PENS + GCAE, twice a week for 6 weeks. All four groups experienced significantly reduced pain (range −2.3 to −4.1 on the McGill Pain Questionnaire short form), improved self-reported disability (range −2.1 to −3.0 on Roland scale) and improved gait velocity (0.04–0.07 m/sec), sustained at 6 months. The GCAE groups experienced significantly fewer fear avoidance beliefs immediately post-intervention and at 6 months than non-GCAE groups. There were no significant side effects. Since brief electrical stimulation (i.e., control-PENS) facilitated comparably reduced pain and improved function at 6 months as compared with PENS, the exact dose of electrical stimulation required for analgesia cannot be determined. GCAE was more effective than PENS alone in reducing fear avoidance beliefs, but not in reducing pain or improving physical function. PMID:18930352

The aim of this study was to assess the feasibility, efficacy and safety of a modified silicone fluted drain tube after video-assisted thoracic surgery (VATS) lung resection. The prospective randomized study included 50 patients who underwent VATS lung resection between March 2015 and June 2015. Eligible patients were randomized into two groups: experimental group (using the silicone fluted drain tubes for chest drainage) and control group (using standard drain tubes for chest drainage). The volume and characteristics of drainage, postoperative (PO) pain scores and hospital stay were recorded. All patients received standard care during hospital admission. In accordance with the exit criteria, three patients were excluded from study. The remaining 47 patients included in the final analysis were divided into two groups: experiment group (N=24) and control group (N=23). There was no significant difference between the two groups in terms of age, sex, height, weight, clinical diagnosis and type of surgical procedure. There was a trend toward less PO pain in experimental group on postoperative day (POD) 1, with a statistically significant difference. Patients in experimental group had a reduced occurrence of fever [temperature (T) >37.4 °C] compared to the control group. The silicone fluted drain tube is feasible and safe and may relieve patient PO pain and reduce occurrence of fever without the added risk of PO complications.

Pilot experiments were carried out to reduce the fluorine (F) and arsenic (As) pollution of roasted corn dried by open ovens in "coal-burning" fluorosis area Yunnan, China. The results indicated that the average emission amount of F and As in briquettes in experimental group were 29.20mg/kg and 0.76 mg/kg in Xiaolongdong, and 46.8 mg/kg and 0.54 mg/kg in Mangbu respectively. The results also indicated that the fixing rate of F and As in briquettes in experimental group was more than 4 times and 1.2 times of that in control group respectively. The average concentration of F and As in roasted corn in experimental group were 3.86 mg/kg and 13.23 μg/kg in Xiaolongdong, and 4.77 mg/kg and 122.96 μg/kg in Mangbu respectively, which reduced by more than 65% and 75% respectively compared with that in control group. Adding local natural calcium-based materials in briquettes can reduce the emission of F and As and their pollution on roasted corn largely, and thus will reduce the risk of fluorosis for residents greatly in "coal-burning" fluorosis area of southwestern China.

Patients with pelvic fractures due to falls: A paradigm that contributed to autopsy-based audit of trauma in Greece

PubMed Central

2011-01-01

Background Evaluation of the pelvic fractures (PFx) population in auditing effective components of trauma care is the subject of this study. Methods A retrospective, case-control, autopsy-based study compared a population with PFx to a control-group using a template with trauma outcome variables, which included demographics, ICD-9, intention, mechanisms, toxicology, Abbreviated Injury Scale (AIS-90), Injury Severity Score (ISS), causes of haemorrhage, comorbidity, survival time, pre-hospital response, in hospital data, location of death, and preventable deaths. Results Of 970 consecutive patients with fatal falls, 209 (21.5%) had PFx and constituted the PFx-group while 761 (78.5%) formed the control-group. Multivariate analysis showed that gender, age, intention, and height of fall were risk factors for PFx. A 300% higher odds of a psychiatric history was found in the PFx-group compared to the control-group (p < 0.001). The median ISS was 50 (17-75) for the PFx-group and 26 (1-75) for the control-group (p < 0.0001). There were no patients with an ISS less than 16 in the PFx group. Associated injuries were significantly more common in the PFx-group than in the control-group. Potentially preventable deaths (ISS < 75) constituted 78% (n = 163) of the PFx-group. The most common AIS3-5 injuries in the potentially preventable subset of patients were the lower extremities in 133 (81.6%), thorax in 130 (79.7%), abdomen/pelvic contents in 99 (60.7%), head in 95 (58.3%) and the spine in 26 (15.9%) patients. A subset of 126 (60.3%) potentially preventable deaths in the PFx-group had at least one AIS-90 code other than the PFx, denoting major haemorrhage. Deaths directly attributed to PFx were limited to 6 (2.9%). The median survival time was 30 minutes for the PFx-group and 20 hours for the control-group (p < 0.001). For a one-group increment in the ISS-groups, the survival rates over the post-traumatic time intervals were reduced by 57% (p < 0.0001). Pre-hospital mortality was significantly higher in the PFx-group i.e. 70.3% of the PFx-group versus 42.7% of the control-group (p < 0.001). Conclusions The PFx-group shared common causative risk factors, high severity and multiplicity of injuries that define the PFx-group as a paradigm of injury for audit. This reduced sample of autopsies substantially contributed to the audit of functional, infrastructural, management and prevention issues requiring transformation to reduce mortality. PMID:21214946

Nasal packing is an option for bleeding control after endoscopic sinus surgery and septoplasty. Although new packing materials have been developed, patients still suffer from pain and require additional analgesics treatments. In this study, a prospective, randomized, and double-blind controlled trial was designed to evaluate the effect of fentanyl-soaked packing on pain after endoscopic sinus surgery and septoplasty. One hundred fifty-two patients who underwent nasal surgeries due to chronic rhinosinusitis or nasal septal deviation were enrolled in this study. At the end of operation, 50 mcg fentanyl-soaked biodegradable synthetic polyurethane foams packing Nasopore or Merocel were applied to a group of 79 patients, and saline-soaked ones were applied to another group of 73 patients. To evaluate the influence of fentanyl on postoperative nasal pain, patients' conditions were assessed via means of Numeric Rating Scale, patient satisfaction, and Ramsay Sedation Scale. In addition, symptoms of headache or sore throat and any signs of cardiopulmonary-relevant indicators were monitored. The fentanyl group had significantly decreased Numeric Rating Scale and increased patient satisfaction in every operation type for the majority of postoperative time periods ( P < .05) with reduced postoperative headache and sore throat compared to the control group. The fentanyl group showed a higher score on Ramsay Sedation Scale than the control group ( P < .05 in group including endoscopic sinus surgery). There were no significant differences in cardiopulmonary-relevant indicators between the 2 groups ( P > .05). Fentanyl group showed significantly reduced postoperative pain without serious adverse effects. We suggest that topical fentanyl application to nasal packs can be a useful method to reduce pain during the early postoperative period after endoscopic sinus surgery and septoplasty.

To explore the effectiveness of comprehensive oral health care to reduce the caries incidence for children with severe early childhood caries (s-ECC) in an urban area in China. A total of 357 children aged 3 to 4 years old and diagnosed with s-ECC were recruited in this randomised controlled, single-blinded clinical trial for 1 year. Children of two different kindergarten classes were enrolled in this study and randomly divided into a test group (205 children) and a control group (152 children). The test group received comprehensive oral health care, which included: oral health examination, oral health education, topical fluoride application and dental treatment, and the children in the control group only received the oral health examination. The evaluation of the oral health questionnaire for parents was also performed. An evaluation was carried out at the time of recruitment and 1 year later to explore the effectiveness of the comprehensive oral health care model. The differences in decayed teeth (dt), decayed tooth surfaces (ds), filled teeth (ft), filled tooth surfaces (fs) and the ratio of ft /(dt + ft) between the two groups were statistically significant (P < 0.001) at 1 year. The incidence of caries in the control group was higher than that of the test group (P = 0.02). The rate of awareness of oral health knowledge (P = 0.01) and the practice of good diet habits (P = 0.02) by parents in the test group were significantly higher than those in the control group. The present study demonstrated that the comprehensive oral health care program reduces and prevents caries amongst children with s-ECC.

Adequate postoperative analgesia with minimal side-effects is essential for early mobilization and recovery in patients undergoing total knee arthroplasty (TKA). High-volume local infiltration analgesia (LIA) with ropivacaine has been introduced, but effects of adjuvants are still debated. We tested the hypothesis that the addition of ketorolac to LIA significantly improves analgesia after TKA. Sixty patients undergoing TKA were randomized to receive intraoperative LIA (ropivacaine 300 mg and epinephrine 0.5 mg) combined with either ketorolac 30 mg (ketorolac group) or saline (control group). After surgery, eight bolus doses of ropivacaine 100 mg combined with either ketorolac 15 mg (ketorolac group) or saline (control group) were administered every 6 h via an intra-articular catheter. The primary outcome was postoperative consumption of i.v. morphine patient-controlled analgesia (PCA). Secondary outcomes were time to first request of i.v. morphine PCA, pain intensity, side-effects, and readiness for hospital discharge. Consumption of i.v. morphine PCA was lower in the ketorolac group vs control group {0-6 h: 0 (0-0) vs 5 (0-10) mg, P<0.0001; 0-48 h: 10 (0-22.5) vs 48.75 (30-82.5) mg, P<0.0001 [median (inter-quartile range, IQR)]}. Time to first request of i.v. morphine PCA was longer in the ketorolac group vs the control group [490 (248-617) vs 223 (115-319) min, P=0.02, median (IQR)]. Early postoperative pain (<48 h) and readiness for hospital discharge were also significantly reduced in the ketorolac group. LIA with ketorolac results in reduced morphine consumption, reduced pain intensity, and earlier readiness for hospital discharge.

There is no conclusive evidence regarding the effect of fasting on different features in asthmatic patients. In the present study, the effect of Ramadan fasting in asthmatic patients and healthy control was studied. Haematological indices, inflammatory mediators, pulmonary function tests (PFT) and respiratory symptoms were evaluated in 15 asthmatic patients compared to 14 healthy matched control group before and after the one-month fasting period in Ramadan. The change in each parameter from the beginning to the end of Ramadan was calculated and referred to as "variation during Ramadan". The values of MCH, MCHC in both groups and monocyte counts in asthmatic patients, were significantly increased but platelet count was reduced in asthmatic and controls respectively compared to pre-Ramadan fasting period (P<0.05 to 0.001). Serum hs-CRP level in control and asthmatic groups was significantly reduced after Ramadan fasting month (P<0.001 for both groups). PFT values after Ramadan fasting month in both groups were non-significantly higher compared to pre-fasting values except FVC. Respiratory symptoms in asthmatic patients were non-significantly but wheeze-o was significantly reduced after Ramadan fasting period in asthma group (P<0.05). There was no significant difference in variations of different parameters during Ramadan fasting period between two groups, although reduction of hs-CRP in asthmatic group was non-significantly higher than control group. These results show that Ramadan fasting period has no negative impact on asthma and may have some positive effect on asthma severity with regard to reduction of hs-CRP concentration and chest wheeze.

Painful diabetic neuropathy (PDN) is a peripheral neuropathic pain condition that is often difficult to relieve. Spinal cord stimulation (SCS) is a proven effective therapy for various types of mixed neuropathic conditions, yet effectiveness of SCS treatment for PDN is not well established. To our knowledge, ours is the first multicentre randomized controlled trial investigating the effectiveness of SCS in patients with PDN. Sixty patients with PDN in the lower extremities refractory to conventional medical therapy were enrolled and followed for 6 months. They were randomized 2:1 to best conventional medical practice with (SCS group) or without (control group) additional SCS therapy, and both groups were assessed at regular intervals. At each follow-up visit, the EuroQoL 5D, the short form McGill Pain Questionnaire (SF-MPQ) and a visual analogue scale (VAS, ranging 0-100) to measure pain intensity were recorded. The average VAS score for pain intensity was 73 in the SCS group and 67 in the control group at baseline. After 6 months of treatment, the average VAS score was significantly reduced to 31 in the SCS group (P<.001) and remained 67 (P=.97) in the control group. The SF-MPQ and EuroQoL 5D questionnaires also showed that patients in the SCS group, unlike those in the control group, experienced reduced pain and improved health and quality of life after 6 months of treatment. In patients with refractory painful diabetic neuropathy, spinal cord stimulation therapy significantly reduced pain and improved quality of life.

Motor control evaluation in subjects with functional ankle instability is questionable when both ankles of the same subject are compared (affected vs non-affected). To compare the postural control and reaction time of ankle muscles among: basketball players with FAI (instability group), basketball players without FAI (non-instability group) and healthy non-basketball-playing participants (control group). Case-control study. Laboratory. Instability (n = 10), non-instability (n = 10), and control groups (n = 11). Centre of pressure variables (area, velocity and sway) were measured with a force platform. Reaction time of ankle muscles was measured via electromyography. A one-way ANOVA demonstrated that there were significant differences between the instability and non-instability groups in the fibularis longus (p < 0.001), fibularis brevis (p = 0.031) and tibialis anterior (p = 0.049) muscles. Repeated-measures ANOVA and post hoc analysis determined significant differences for the area between the instability and non-instability groups (p = 0.001). Basketball players with FAI have reduced postural control and longer reaction time of the fibularis and tibialis anterior muscles. Copyright © 2014 Elsevier Ltd. All rights reserved.

The impact of ascorbic acid supplementation against ethanol induced Leydig cell toxicity was studied in guinea pigs. Male guinea pigs were exposed to ethanol (4g/kgb.wt.) for 90 days. After 90 days, ethanol administration was completely stopped and animals in the ethanol group were divided into abstention group and ascorbic acid supplemented group (25mg/100gb.wt.) and those in control group were maintained as control and control+ascorbic acid group. Ethanol administration reduced the serum testosterone and LH (luteinising hormone) levels and elevated estradiol levels. Cholesterol levels in Leydig cell were increased whereas the mRNA and protein expressions of StAR (steroidogenic acute regulatory) protein, cytochrome P450scc (cytochrome p450side chain cleavage enzyme), 3β-HSD (3β-hydroxysteroid dehydrogenase), 17β-HSD (17β-hydroxysteroid dehydrogenase) and LH receptor were drastically reduced. Administration of ascorbic acid resulted in alteration of all these parameters indicating enhanced recovery from ethanol induced inhibition of Leydig cell steroidogenesis. Although abstention could also reduce the inhibition of steroidogenesis, this was lesser in comparison with ascorbic acid supplemented group. © 2013 Published by Elsevier B.V.

Intra-abdominal adhesions are fibrous bands that develop after abdominal surgery or inflammation and cause mortality and morbidity following surgeries. This study aimed to assess the effects of bupivacaine, saline and two doses of lidocaine, after peritoneal lavage and to compare their effects in reducing abdominal adhesions in rat. In a blinded, randomised, placebo-controlled clinical trial, 50 female rats were anaesthetised and the parietal peritoneum was scratched to induce punctate bleeding. The rats were randomly assigned to five groups: saline, lidocaine 2% (3 and 6 mg/kg), bupivacaine 0.25% (2 mg/kg) and control (no irrigation). The peritoneal cavity was irrigated with the appropriate solution during laparotomy. Two weeks later, re-laparotomy was performed. The quantity, quality, severity and scores of adhesions were recorded and compared. The quantity and quality of adhesions were significantly higher in the control group than in the lidocaine (6 mg/kg) and bupivacaine groups. The quality of the adhesions was higher in the normal saline group than in the lidocaine (6 mg/kg) and bupivacaine groups. The severity of adhesions between the lidocaine 3 and 6 mg/kg groups and between the lidocaine 3 mg/kg and saline groups was lower than that in the control group. Using lidocaine (6 mg/kg) and bupivacaine lavage in first laparotomy reduces abdominal peritoneal obstruction because of the formation of adhesion bands.

Postoperative pain alters physiological functions and delays discharge. Perioperative local anesthetics are effective analgesics in the immediate 1- to 2-day postoperative period, but acute pain often lasts longer. The goal of this work was to develop a local anesthetic formulation adhering to an intraoperative implanted device that reduces pain for at least 3 days after surgery. Six groups, each with 8 rats, were studied. In a control group (group I), one 1.2-cm-long incision of the skin was followed by blunt dissection to separate the skin away from the underlying tissues and closing with 2 sutures. In 3 of the treatment groups, the same surgical procedure was used, with the subcutaneous space formed by the blunt dissection lined with a 1-cm square patch of hernia mesh coated with poly lactide co-glycolic acid microspheres containing approximately 17 mg of bupivacaine (group II), no drug (placebo; group III), or bupivacaine free-base powder (group IV). Uncoated mesh implants (group V) served as a secondary control. A standard bupivacaine solution (0.4 mL, 0.5%; 2-mg dose) was infiltrated subcutaneously 30 minutes before the surgery and served as a standard control (group VI). Mechanosensitivity of the skin was tested by the local subcutaneous muscle responses to cutaneous tactile stimulation by von Frey hairs with forces of 4 g (for allodynia) and 15 g (for hyperalgesia) preoperatively and for 7 postoperative days. Control rats (group I) showed mechanohypersensitivity, indicative of postoperative allodynia and hyperalgesia, for all 7 postoperative days. Mechanohyperalgesia in rats that received mesh coated with bupivacaine-releasing microspheres (group II) was reduced during this period to 13% of control postoperative values (P < 0.001); mesh coated with bupivacaine base (group IV) reduced it by 50% (P = 0.034). The placebo mesh (group III) and uncoated mesh (group V) caused no significant reduction of mechanohypersensitivity, and bupivacaine solution infiltrated before the incision (group VI) reduced hypersensitivity for only approximately 2 hours, an overall insignificant effect. Bupivacaine slowly released for 72 hours from microspheres adsorbed to the hernia mesh significantly suppresses evoked postoperative hypersensitivity for at least 1 week and is more effective than a suspension of these microspheres or preoperative single-shot infiltration of bupivacaine.

Effects of neurophathologic changes and expression of Glu and 60 nNOS were observed in acute isocarbophos and phoxim poisoning in mice. KM male mice were randomly divided into three groups, which were control, non-treated and Huperzine A (HupA)-treated groups. The control group was given tween-80. Nontreated group was given isocarbophos (14.7 mg/kg) or phoxim (1702 mg/kg). HupA-treated group was given HupA 2h before phoxim or isocarbophos. Twenty-four hours after exposure, the whole brain was removed and adjacent coronal sections was obtained. One part of sections were stained with toluidine blue. The part of sections were used to assessed the expression of Glu and nNOS in the cortex and hippocampal of brain by immunohistochemistry. Compared to control group, non-treated group was observed nissal body nembers reduced and dyeing light. The animals of HupA protective group were observed nissal body nembers reduced, but the lesional degree was lighter obviously than non-treated group. The statistically reduced of the expression of Glu (P<0.01), the elevation of nNOS (P<0.01), after Isocarbophos intoxication were observed. Compared to non-treated group, the significant elevation of Glu (P<0.01) and reduced of nNOS (P<0.01) was observed on HupA-treated groups. Whereas for phoxim treatment, no changes were observed. HupA have protective effect against glutamatergic systems disorder caused by Isocarbophos poisoning. Administration of HupA have no effects of the neurotransmitter changes induces by acute poisoning of phoxim. It is different for the toxic effect mechanism of the two organophosphate.

Objective. To test the effectiveness of guided imagery (GI) and progressive muscle relaxation (PMR) as stress reducing interventions in patients with prostate and breast cancer who undergo chemotherapy. Methods. Patients were randomly assigned to either the control group or the intervention group (PMR and GI). Patients were observed for a total duration of 3 weeks and assessed with the SAS and BECK-II questionnaires for anxiety and depression, respectively, in addiotion to two biological markers (saliva cortisol and saliva amylase) (trial registration number: NCT01275872). Results. 256 patients were registered and 236 were randomly assigned. In total 104 were randomised to the control group and 104 to the intervention group. Intervention's mean anxiety score and depression score changes were significantly different compared to the control's (b = −29.4, p < 0.001; b = −29.4, p < 0.001, resp.). Intervention group's cortisol levels before the intervention (0.30 ± 0.25) gradually decreased up to week 3 (0.16 ± 0.18), whilst the control group's cortisol levels before the intervention (0.21 ± 0.22) gradually increased up to week 3 (0.44 ± 0.35). The same interaction appears for the Amylase levels (p < 0.001). Conclusions. The findings showed that patients with prostate and breast cancer undergoing chemotherapy treatment can benefit from PMR and GI sessions to reduce their anxiety and depression. PMID:26347018

To demonstrate the effectiveness of medical-grade stainless steel Water Works Douching Device for treating abnormal vaginal odor in comparison with a commercially available over-the-counter plastic douching device. In a multicenter study, 140 women with perceived vaginal odor with no vaginal infection were randomized to either Water Works or control group in a 1:1 ratio and were douched daily for 4 weeks. A visual analog scale (VAS) was used to assess the intensity of vaginal odor. Primary outcome included subject assessment of odor improvement and Nugent Gram stain score of vaginal secretions. Secondary outcome compared the efficacy and safety of Water Works with control douching device. Each patient underwent baseline, week 2, and week 4 visits. The final analytic sample consisted of 96 women. Success score at 4 weeks was 78% for the Water Works group and 38.5% for the control group. Mean VAS was significantly reduced, and Nugent and Lactobacillus scores were maintained in both groups. In the Water Works group, VAS was reduced from 7.3 ± 0.3 to 1.8 ± 0.6 (p < .001) after 4 weeks. In the control group, baseline versus 4 weeks VAS was 7.2 ± 0.3 and 3.4 ± 0.8 (p < .003). Women reported significant reduction of vaginal odor after douching with water for 4 weeks without any alteration of vaginal flora. The Water Works Douching Device was superior to over- the-counter device in reducing vaginal odor.

Some scientific studies, with controversial results, have evaluated the efficacy in reducing pain of some different local anesthetic molecules, which were administered at different dosages and in different ways. The primary goal of this randomized, controlled, prospective study (Clinical Trials.gov ID NCT00599144) was to assess the effectiveness of 0.5% bupivacaine for pain control after video-laparoscopic cholecystectomy at its optimal dosage of 2 mg/kg infiltrated in the muscular fasciae of the trocars, or positioned in the gallbladder soaking a sheet of regenerated oxidized cellulose (Tabotamp). A total of 45 patients underwent elective video-laparoscopic cholecystectomy. They were randomized in three groups each made of 15 patients: group A (bupivacaine-soaked Tabotamp positioned in the gallbladder bed), group B (bupivacaine infiltrated in the muscular fasciae of the trocars' seat), group C (control group, not using local anesthetic). Six and twenty-four hours after the intervention, the nature of the pain and its intensity were recorded with the use of a Visual Analogue Scale (VAS). Six hours after the intervention, VAS average was 29.6 +/- 10.92 for group A, 25.86 +/- 16.06 for group B, and 36.13 +/- 16.62 for group C. At 24 h, we recorded 19.26 +/- 15.81, 18.53 +/- 12.3, and 20.46 +/- 20.08 for groups A, B, and C, respectively (p > 0.05). Comparing groups A and B between them and with the control group at 6 and 24 h, we deduced how only the first group showed a statistically significant advantage (p < 0.05) in reducing visceral and shoulder pain compared with the two other groups. Wound infiltration resulted in being statistically favorable in reducing parietal pain only when compared with Group A. For groups A and B, bupivacaine significantly reduced the use of postoperative pain killers. Bupivacaine, either infiltrated in trocars' wounds or kept soaked in a regenerated oxidized cellulose sheet positioned in the gallbladder bed, although safe and not economically demanding, can increase postoperative comfort.

Posttraumatic stress disorder (PTSD) is often associated with impaired fear inhibition and decreased safety cue processing; however, studies capturing the cognitive aspect of inhibition and contextual cue processing are limited. In this fMRI study, the role of contextual cues in response inhibition was investigated. Male medication-naive war veterans with PTSD, male control veterans (combat controls) and healthy nonmilitary men (healthy controls) underwent fMRI while performing the stop-signal anticipation task (SSAT). The SSAT evokes 2 forms of response inhibition: reactive inhibition (outright stopping) and proactive inhibition (anticipation of stopping based on contextual cues). We enrolled 28 veterans with PTSD, 26 combat controls and 25 healthy controls in our study. Reduced reactive inhibition was observed in all veterans, both with and without PTSD, but not in nonmilitary controls, whereas decreased inhibition of the left pre/postcentral gyrus appeared to be specifically associated with PTSD. Impaired behavioural proactive inhibition was also specific to PTSD. Furthermore, the PTSD group showed a reduced right inferior frontal gyrus response during proactive inhibition compared with the combat control group. Most patients with PTSD had comorbid psychiatric disorders, but such comorbidity is common in patients with PTSD. Also, the education level (estimate of intelligence) of participants, but not of their parents, differed among the groups. Our findings of reduced proactive inhibition imply that patients with PTSD show reduced contextual cue processing. These results complement previous findings on fear inhibition and demonstrate that contextual cue processing in patients with PTSD is also reduced during cognitive processes, indicating a more general deficit.

The aim of this study was to study RAS-siRNA blocking RAS pathway and suppressing cell growth in human oesophageal squamous cell carcinoma in nude mice. The methods in this study was to construct RAS-siRNA expression vector, establish 40 oesophageal squamous cell carcinoma xenograft animal models and divided them into five groups: control group, siRNA control group, RAS-siRNA group, paclitaxel group and RAS-siRNA and paclitaxel group. We observed tumour growth in nude mice, studied histology by HE staining, tumour growth inhibition by TUNEL assay and detected the RAS, MAPK and cyclin D1 protein expression by immunohistochemistry and western blot. We have obtained the following results: (i) successfully established animal models; (ii) nude mice in each group after treatment inhibited tumour volume was significantly reduced compared with the control group (p < 0.05); (iii) compared with the control group, the number of apoptotic cells were significantly increased in the siRNA control group and the RAS-siRNA group, and the number of apoptosis cells in the paclitaxel and RAS-siRNA group is significantly most than the paclitaxel group and RAS-siRNA group (p < 0.05); and (iv) after treatment, RAS, MAPK and cyclin D1 expression in five groups was decreasing gradually. After adding paclitaxel, the protein expression in the paclitaxel and RAS-siRNA group was significantly lower than that of paclitaxel group, negative control and paclitaxel group (p < 0.05). We therefore conclude that RAS-siRNA can block the RAS signal transduction pathway, reduce the activity of tumour cells, arrest tumour cell cycle, promote apoptosis, inhibit cell proliferation and increase tumour cell sensitivity to chemotherapeutic drugs.

The effectiveness of a hospital discharge education program including information on postnatal depression was evaluated to reduce psychological morbidity after childbirth. A randomized controlled trial (RCT) was conducted in a regional hospital in Taipei. Two hundred first-time mothers agreed to take part and were randomly allocated to an intervention group (n=100) or control group (n=100). The intervention group received discharge education on postnatal depression provided by postpartum ward nurses. The control group received general postpartum education. The main outcome measure was the Edinburgh Postnatal Depression Scale (EPDS) administered by postal questionnaire at six weeks and three months after delivery. Women who received discharge education intervention on postnatal depression were less likely to have high depression scores when compared to the control group at three months postpartum. A discharge educational intervention including postnatal depression information given to women during the postpartum stay benefits psychological well-being. A postpartum discharge education program including information on postnatal depression should be integrated into postpartum discharge care in general practice. 2009 Elsevier Ireland Ltd.

REDUCED INTENSITY IN GAIT-SLIP TRAINING CAN STILL IMPROVE STABILITY

Perturbation training with “free” slips (i.e., with long slip distance) has been able to successfully improve stability and to reduce the incidence of falls among older adults. Yet, it is unclear whether a highly constrained training with reduced slip distance (and hence training intensity) can achieve similar effects. The purpose of this study was to investigate whether short-distance slips could also improve the control of stability, and whether such improvements could be generalized to a novel, “free” slip. Thirty-six young subjects were randomly assigned to either one of the two training groups, which underwent seven training trials with constrained slips of either 12-cm or 18-cm in distance before encountering a novel, “free” slip (up to 150cm) in the test trial; or the control group, which only experienced the same test trial of a novel, “free” slip. The results showed that while both training groups were able to significantly improve their control of stability in training; the 18-cm group had significantly better reactive control of stability than the 12-cm group. During the “free” slip, such advantage enabled the 18-cm group to exhibit significantly less balance loss incidence than 12-cm group (58.3 vs. 83.3%) and the controls (100%). These differences could be fully accounted for when we assume that the central nervous system directly controls slip velocity or slip distance during adaptation, whereby the level of similarity between training trials and the test trial governs the degree of generalization. The findings that low intensity training may still improve stability warrant further investigations among older adults. PMID:24835473

Tele-cardiology is the use of information technologies that help prolong survival, improve quality of life and reduce costs in health care. Heart failure is a chronic disease that leads to high care costs. To determine the effectiveness of telemetric monitoring for controlling clinical variables, reduced emergency room visits, and cost of care in a group of patients with heart failure compared to traditional medical consultation. A randomized, controlled and open clinical trial was conducted on 40 patients with Heart failure in a tertiary care centre in north-western Mexico. The patients were divided randomly into 2 groups of 20 patients each (telemetric monitoring, traditional medical consultation). In each participant was evaluated for: blood pressure, heart rate and body weight. The telemetric monitoring group was monitored remotely and traditional medical consultation group came to the hospital on scheduled dates. All patients could come to the emergency room if necessary. The telemetric monitoring group decreased their weight and improved control of the disease (P=.01). Systolic blood pressure and cost of care decreased (51%) significantly compared traditional medical consultation group (P>.05). Admission to the emergency room was avoided in 100% of patients in the telemetric monitoring group. In patients with heart failure, the telemetric monitoring was effective in reducing emergency room visits and saved significant resources in care during follow-up.

Prospective controlled intervention study. To evaluate a specific segmental muscle training program of the lumbar spine in order to prevent and reduce low back pain in young female teamgym gymnasts. Teamgym is a team sport comprising three events: trampette, tumbling and floor programme. In a recent study, it was found that teamgym gymnasts practice and compete despite suffering from back pain. Specific muscle control exercises of the lumbar spine have shown good results in reducing pain intensity and functional disability levels in patients with low back pain. To our knowledge, this type of training has not been studied in an adolescent athletic population before. Fifty-one gymnasts, with and without LBP, 11-16 years old, from three top-level gymnastics team participated in the study comprising 12 weeks. Every day the gymnasts answered a questionnaire regarding low back pain. After baseline (4 weeks) the intervention group performed a specific segmental muscle training program. Twenty-four gymnasts (47%) reported low back pain during baseline. Nine gymnasts failed to answer the questionnaire every day and the following results are based on 42 gymnasts (intervention group, n = 30, and control group, n=12). Gymnasts in the intervention group reported significantly less number of days with low back pain at completion compared to baseline (P=0.02). Gymnasts in the control group showed no difference in terms of days with low back pain or intensity of low back pain between baseline and completion. Eight gymnasts (out of 15) with LBP in the intervention group became pain free. Specific segmental muscle control exercises of the lumbar spine may be of value in preventing and reducing low back pain in young teamgym gymnasts.

Alternative C activation is involved in the pathogenesis of ANCA-associated vasculitis. However, glucocorticoids used as treatment contribute to the morbidity and mortality of vasculitis. We determined whether avacopan (CCX168), an orally administered, selective C5a receptor inhibitor, could replace oral glucocorticoids without compromising efficacy. In this randomized, placebo-controlled trial, adults with newly diagnosed or relapsing vasculitis received placebo plus prednisone starting at 60 mg daily (control group), avacopan (30 mg, twice daily) plus reduced-dose prednisone (20 mg daily), or avacopan (30 mg, twice daily) without prednisone. All patients received cyclophosphamide or rituximab. The primary efficacy measure was the proportion of patients achieving a ≥50% reduction in Birmingham Vasculitis Activity Score by week 12 and no worsening in any body system. We enrolled 67 patients, 23 in the control and 22 in each of the avacopan groups. Clinical response at week 12 was achieved in 14 of 20 (70.0%) control patients, 19 of 22 (86.4%) patients in the avacopan plus reduced-dose prednisone group (difference from control 16.4%; two-sided 90% confidence limit, -4.3% to 37.1%; P =0.002 for noninferiority), and 17 of 21 (81.0%) patients in the avacopan without prednisone group (difference from control 11.0%; two-sided 90% confidence limit, -11.0% to 32.9%; P =0.01 for noninferiority). Adverse events occurred in 21 of 23 (91%) control patients, 19 of 22 (86%) patients in the avacopan plus reduced-dose prednisone group, and 21 of 22 (96%) patients in the avacopan without prednisone group. In conclusion, C5a receptor inhibition with avacopan was effective in replacing high-dose glucocorticoids in treating vasculitis. Copyright © 2017 by the American Society of Nephrology.

The crossmatch test is essential prior to kidney transplantation (tx) to confirm compatibility between the donor and the recipient. However, its results can be misleading due to "undetectable antibodies" in the recipient's serum. To establish if undetectable autoantibodies are responsible for a positive result, an auto-crossmatch test can be performed. In this study, we aim to determine the long-term prognostic value of auto-flow cytometric auto-crossmatch (FCXM) test on kidney survival in kidney tx recipients. The primary outcome variable was reduced renal function. Secondary endpoints were incidence of biopsy-confirmed chronic antibody-mediated rejection (CAMR) and recurrent glomerulonephritis (GN). There were no differences regarding initial serum creatinine levels between the study and control groups (P = .441). Patients who had positive auto-B FCXM had a significantly reduced renal function compared with the control group (P = .016). Four patients developed biopsy-confirmed CAMR in the study group and 1 patient in the control group (P = .047). Five patients had biopsy-confirmed recurrent GN in the GN study group, and only 1 patient had recurrent GN in the GN control group (P = .026). Kidney transplant recipients with positive auto-FCXM test had significantly reduced renal function and a higher incidence of recurrent GN and CAMR compared with the control group. The findings of this study suggest a potential role of auto-antibody causing positive auto-FCXM test result, meanwhile increasing the risk of CAMR, recurrent GN, and new-onset diabetes after tx.

Perioperative administration of immunoenriched diets attenuates the perioperative inflammatory response and reduces postoperative infection complications. However, many questions still remain unresolved in this area, such as the length of diet administration, diet composition, and the mechanisms involved. We performed an open, randomized, triple-arm study comparing the effect of two perioperative feeding regimens with a postoperative one. 46 candidates for major elective surgery for malignancy in the upper gastrointestinal tract were randomized to drink preoperatively either 1 L of an immunoenriched formula (Impact) for 5 days (IEF group) or 1 L of Impact plus (Impact enriched with glycine) for 2 days (IEF plus group). The same product as the patient received preoperatively was given to both groups for 7 days postoperatively. In the control group (CON group), patients only received Impact for 7 days postoperatively; there was no preoperative treatment. The main outcome measures were postoperative C-reactive protein (CRP) serum levels. In the two preoperatively supplemented groups (treatment groups), perioperative endotoxin levels, CRP (postoperative day 7), and TNF-alpha (postoperative days 1 and 3) levels were significantly lower compared to the CON group (p < .01). Furthermore, the length of postoperative IMU/ICU stay (Impact 1.9 +/- 1.3 days; Impact plus 2.2 +/- 1.1 days; control group 5.9 +/- 0.8 days) and length of hospital stay (Impact 19.7 +/- 2.3 days; Impact plus 20.1 +/- 1.3 days; control group 29.1 +/- 3.6 days) were both reduced in the treatment groups compared to the control group. Infectious complications (Impact 2/14 (14%); Impact plus 5/17 (29%); control group 10/15 (67%)) also showed a trend toward reduction in the treatment groups. Perioperative administration of an immunoenriched diet significantly reduces systemic perioperative inflammation and postoperative complications in patients undergoing major abdominal cancer surgery, when compared with postoperative diet administration alone. A shortened preoperative feeding regimen of 2 days with Impact enriched with glycine (Impact plus) was as effective as Impact administered for 5 days preoperatively.

Action video game training reduces the Simon Effect.

A number of studies have shown that training on action video games improves various aspects of visual cognition including selective attention and inhibitory control. Here, we demonstrate that action video game play can also reduce the Simon Effect, and, hence, may have the potential to improve response selection during the planning and execution of goal-directed action. Non-game-players were randomly assigned to one of four groups; two trained on a first-person-shooter game (Call of Duty) on either Microsoft Xbox or Nintendo DS, one trained on a visual training game for Nintendo DS, and a control group who received no training. Response times were used to contrast performance before and after training on a behavioral assay designed to manipulate stimulus-response compatibility (the Simon Task). The results revealed significantly faster response times and a reduced cost of stimulus-response incompatibility in the groups trained on the first-person-shooter game. No benefit of training was observed in the control group or the group trained on the visual training game. These findings are consistent with previous evidence that action game play elicits plastic changes in the neural circuits that serve attentional control, and suggest training may facilitate goal-directed action by improving players' ability to resolve conflict during response selection and execution.

To compare the effects of a vapocoolant spray and an eutectic mixture of local anesthetics (EMLA) cream in reducing pain during needle electromyography examination. Randomized controlled trial. Physical medicine and rehabilitation department of a university hospital. Adults who underwent needle electromyography (N=99) were randomized to 1 of 2 experimental groups or the control group. Two patients dropped out during the study. In the experimental groups, vapocoolant spray or EMLA cream were applied before needle electromyography. In the control group, needle electromyography was performed without pretreatment. Intensity of pain associated with needle electromyography was assessed using a 100-mm visual analog scale (VAS). Patient satisfaction and preference for repeated use were measured using a 5-point Likert scale. VAS score for pain intensity was significantly lower in the spray group (31.9; 95% confidence interval [CI], 22.0-41.7) compared with the control group (52.9; 95% CI, 45.9-60.0; P=.002), whereas there was no significant difference between the EMLA cream group (42.4; 95% CI, 34.2-50.7) and the control group. Patient satisfaction and preference for repeated use were higher in the spray group than the EMLA group. Vapocoolant spray was more effective than EMLA cream in reducing pain during needle electromyography. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc.

Purpose Total knee arthroplasty (TKA) accompanies the risk of bleeding and need for transfusion. There are several methods to reduce postoperative blood loss and blood transfusion. One such method is using tranexamic acid during TKA. The purpose of this study was to confirm whether tranexamic acid reduces postoperative blood loss and blood transfusion after TKA. Materials and Methods A total of 100 TKA patients were included in the study. The tranexamic acid group consisted of 50 patients who received an intravenous injection of tranexamic acid. The control included 50 patients who received a placebo injection. The amounts of drainage, postoperative hemoglobin, and transfusion were compared between the groups. Results The mean amount of drainage was lower in the tranexamic acid group (580.6±355.0 mL) than the control group (886.0±375.5 mL). There was a reduction in the transfusion rate in the tranexamic acid group (48%) compared with the control group (64%). The hemoglobin level was higher in the tranexamic acid group than in the control group at 24 hours postoperatively. The mean units of transfusion were smaller in the tranexamic acid group (0.76 units) than in the control group (1.28 units). Conclusions Our data suggest that intravenous injection of tranexamic acid decreases the total blood loss and transfusion after TKA. PMID:27595071

OBJECTIVE To evaluate the association of airborne colony-forming units (CFU) at incision sites during implantation of prostheses with the incidence of either incisional or prosthesis-related surgical site infections. DESIGN Randomized, controlled trial. SETTING Primary, public institution. PATIENTS Three hundred patients undergoing total hip arthroplasty, instrumented spinal procedures, or vascular bypass graft implantation. METHODS Patients were randomly assigned in a 1:1 ratio to either the intervention group or the control group. A novel device (Air Barrier System), previously shown to reduce airborne CFU at incision sites, was utilized in the intervention group. Procedures assigned to the control group were performed without the device, under routine operating room atmospheric conditions. Patients were followed up for 12 months to determine whether airborne CFU levels at the incision sites predicted the incidence of incisional or prosthesis-related infection. RESULTS Data were available for 294 patients, 148 in the intervention group and 146 in the control group. CFU density at the incision site was significantly lower in the intervention group than in the control group (P<.001). The density of airborne CFU at the incision site during the procedures was significantly related to the incidence of implant infection (P=.021). Airborne CFU densities were 4 times greater in procedures with implant infection versus no implant infection. All 4 of the observed prosthesis infections occurred in the control group. CONCLUSION Reduction of airborne CFU specifically at the incision site during operations may be an effective strategy to reduce prosthesis-related infections. clinicaltrials.gov Identifier: NCT01610271 Infect Control Hosp Epidemiol 2016;1-8.

Different sources of saponins are known to have hypocholesterolemic activity with varying degrees of efficacy. We hypothesize that karaya root saponin would efficiently reduce cholesterol. The aim of this study is to examine the comparative hypocholesterolemic effect of karaya root saponin in rats fed a high-cholesterol diet. Sixty male Wister-Imamichi rats were divided into 5 groups of 12 rats each constituting of the following: control group, soybean saponin-supplemented group, karaya root saponin-supplemented group, quillaja saponin-supplemented group, and tea saponin-supplemented group. Compared with the control diet, both the karaya root- and quillaja saponin-supplemented diets significantly reduced (P < .05) serum cholesterol and atherogenic index. Karaya root saponin significantly increased the serum high-density lipoprotein cholesterol, high-density lipoprotein cholesterol/cholesterol ratio, and fecal cholesterol concentrations (P < .05). The triacylglycerol concentration was significantly reduced only in the quillaja saponin-supplemented rats (P < .05). All the tea, soybean, karaya root, and quillaja saponins significantly reduced low-density lipoprotein cholesterol, and the greatest reduction was observed with karaya root saponin. Highest fecal bile acid concentration was found with quillaja saponin, whereas highest liver bile acid concentration was observed with karaya root saponin-supplemented rats (P < .05). These results collectively suggest that karaya root saponin can efficiently reduce serum cholesterol concentration in rats.

To evaluate whether Baby-guard-a new medical device with an ergonomic 3-chamber inflatable abdominal belt-can reduce complications associated with vaginal delivery. A randomized controlled single-blind prospective study of 80 pregnant women delivering at term was conducted at San Giuseppe Hospital, Empoli, Italy. In the study group (n=40), the abdominal belt was inflated to optimal therapeutic pressures. In the control group (n=40), the abdominal belt was inflated to minimal, non-therapeutic pressures. Factors relating to maternal, fetal, and labor complications during vaginal delivery were evaluated. Compared with the control group, women in the study group experienced a lower incidence of perineal and cervical lacerations (P<0.001); reduced use of the Kristeller maneuver (P<0.001); shorter duration of the second stage of labor (P<0.001); less psychologic and physical fatigue (P<0.001); fewer maternal requests for cesarean delivery during labor (P<0.001); fewer vacuum extractions (P<0.01); and fewer cesarean deliveries (P<0.02). No neonatal intensive care unit admissions were recorded in the study group versus 7 in the control group (P<0.012). Use of the ergonomic 3-chamber inflatable abdominal belt system reduced the incidence of risks associated with vaginal labor. Clinical trials.gov identifier: NCT01566331.

RPMI 8226 cells were treated with different drugs, CCK-8 method was used to detect cell proliferation, flow cytometry was used to detect the cell cycle and apoptosis, reverse transcription PCR was used to detect Notch1 and NF-κB mRNA expression level. Compared with DMSO control group, RPMI8226 cell proliferation inhibition rate in all the PM, prednisolone and CP groups increased significantly with prolonging of time (r of 0.994,0.996,0.999, respectively, P<0.001). And at the same time, the inhibitory rate of cell proliferation was significantly different; the cell inhibitory rate in PM group was lowest, that in CP group was highgest, that in prednissone group was intermediate (P<0.01). After 48 hours, compared with the DMSO control group, the G 1 /G 0 cell proportion in treatment group increased significantly, S phase cell proportion decreased significantly, especially in PM and CP groups. The G 2 /M phase cell proportion increased in PM group, while reduced in the prednisolone and the CP groups. After 48 hours, compared with the DMSO control group, RPMI 8226 cell apoptosis rate increased as follow: in PM, pre-dnisolone and CP group(P<0.01). After 48 hours, compared with the DMSO control group, Notch1 and NF-κB mRNA expression in the prednisolone, the PM and the CP group decreased significantly(P<0.001). CP metronomic chemotherapy can significantly reduce RPMI 8226 cell proliferation, promote RPMI 8226 cell apoptosis, arrest RPMI 8226 cells mainly in the G 1 /G 0 phase, and significantly reduce Notch1 and NF-κB expression levels. It is suggested that Notch1/NF-κB signaling pathways is involved in CP metronomic chemotherapy for MM.

It has been suggested that placing critically ill ventilated patients in a semirecumbent position minimizes the likelihood of nosocomial pneumonia. This pilot study explores whether the incidence of ventilator-acquired pneumonia (VAP) can be reduced by elevating the head of the bed to 45 degrees. The design is quantitative in nature, using a randomized controlled trial. The method involves adult ventilated patients being randomly assigned to one of two positions, i.e. 45 degrees raised head of bed (treatment group) or 25 degrees raised head of bed (control group). Data collection relied upon the diagnosis of clinically suspected and microbiologically confirmed pneumonia defined by the Consensus Conference on VAP. Thirty patients were included in the study--17 in the treatment group and 13 in the control group. Results showed that 29% (five) in the treatment group and 54% (seven) in the control group contracted VAP (P < 0.176). There was a trend towards a reduction in VAP in the patients nursed at 45 degrees. However, because of the sample size this difference did not reach statistical significance.

Objective Re-operative cardiac surgery is complicated in part because of extensive adhesions encountered during the second operation. The purpose of this study was to examine the effects of alcohol with and without resveratrol (red wine vs. vodka), on post-operative pericardial adhesion formation in a porcine model of hypercholesterolemia and chronic myocardial ischemia. Methods Male Yorkshire swine were fed a high-cholesterol diet to simulate conditions of coronary artery disease followed by surgical placement of an ameroid constrictor to induce chronic ischemia. Post-operatively, control pigs continued their high-cholesterol diet alone, while the two experimental groups had diets supplemented with either red wine or vodka. Seven weeks after ameroid placement, all animals underwent re-operative sternotomy. Results Compared to controls, pericardial adhesion grade was markedly reduced in the vodka group while there was no difference in the wine group. Intramyocardial fibrosis was significantly reduced in the vodka group compared to controls. There was no difference in expression of proteins involved in focal adhesion formation between any groups (FAK, Int α5, Int β1, Paxillin, Vinculin, PYK2, PKCε, p-PKCε). The wine group exhibited elevated CRP levels vs. control and vodka group. Conclusions Post-operative vodka consumption markedly reduced the formation of pericardial adhesions and intramyocardial fibrosis while red wine had no effect. Analysis of protein expression did not reveal any obvious explanation for this phenomenon, suggesting a post-translational effect of alcohol on fibrous tissue deposition. The difference in adhesion formation in the vodka vs. wine groups may be due to increased inflammation in the wine group. PMID:22244558

This pilot study examined the effectiveness of an attachment-based intervention program, PRERAYMI, based on video technique, psychological counseling and developmental guidance in improving the style of interaction and emotion regulation of adolescent mothers and their infants after 3 and 6 months of intervention. Analyses revealed that adolescent mothers who participated in the intervention (vs. control group adolescent mothers) increased their Sensitivity and reduced their Controlling style after both 3 and 6 months of treatment. Infants who participated in the intervention (vs. control group infants) increased their Cooperative style and reduced their Passive style from 3 to 9 months. Moreover, the intervention group dyads (vs. control group dyads) increased the amount of time spent in affective positive coordination states (matches), decreased the amount of time spent in affective mismatches, and had a greater ability to repair mismatches from 3 to 9 months. Furthermore, the intervention group dyads (vs. control group dyads) increased the amount of time spent in reciprocal involvement in play with objects from 3 to 9 months. The quality of maternal attachment did not affect the intervention effect. PMID:26941673

A numerical procedure for grouping actuators in order to reduce the number of degrees of freedom in an active noise control system is evaluated using experimental data. Piezoceramic actuators for reducing aircraft interior noise are arranged into groups using a nonlinear optimization routine and clustering algorithm. An actuator group is created when two or more actuators are driven with the same control input. This procedure is suitable for active control applications where actuators are already mounted on a structure. The feasibility of this technique is demonstrated using measured data from the aft cabin of a Douglas DC-9 fuselage. The measured data include transfer functions between 34 piezoceramic actuators and 29 interior microphones and microphone responses due to the primary noise produced by external speakers. Control inputs for the grouped actuators were calculated so that a cost function, defined as a quadratic pressure term and a penalty term, was a minimum. The measured transfer functions and microphone responses are checked by comparing calculated noise reductions with measured noise reductions for four frequencies. The grouping procedure is then used to determine actuator groups that improve overall interior noise reductions by 5.3 to 15 dB, compared to the baseline experimental configuration.

Clinical training in managing conflicts and preventing violence seldom contains sensory modulation (SM) as a method to de-escalate and prevent restraint and seclusion. Sensory-based interventions promote adaptive regulation of arousal and emotion. SM is a complementary approach that is associated with reduced rates of seclusion and restraint in mental healthcare, but there is need for more research in this area. Using SM to reduce restraint and seclusion in inpatient mental health care. The study included two similar psychiatric units where one unit implemented SM and one unit served as the control group. In the very beginning of the study, a staff-training program in the use of SM including assessment tools and intervention strategies was established. Data on restraint and forced medicine were sampled post the course of the year of implementation and compared with the control group. The use of belts decreased with 38% compared to the control group. The use of forced medication decreased with 46% compared to the control group. Altogether the use of physical restraint and forced medication decreased significantly with 42% (p < .05). Implementing a SM approach in mental healthcare facilities has a significant effect on the reduction of restraint and seclusion. As a part of the implementation, staff training and education in SM are crucial.

Objective To determine if bacterial colonization of drains can be reduced by local antiseptic interventions. Summary Background Drains are a potential source of bacterial entry into surgical wounds and may contribute to surgical site infection (SSI) after breast surgery. Methods Following IRB approval, patients undergoing total mastectomy and/or axillary lymph node dissection were randomized to standard drain care (control) or drain antisepsis (treated). Standard drain care comprised twice daily cleansing with alcohol swabs. Antisepsis drain care included 1) a chlorhexidine disc at the drain exit site and 2) irrigation of the drain bulb twice daily with dilute sodium hypochlorite (Dakin’s) solution. Cultures results of drain fluid and tubing were compared between control and antisepsis groups. Results Overall, 100 patients with 125 drains completed the study with 48 patients (58 drains) in the control group and 52 patients (67 drains) in the antisepsis group. Cultures of drain bulb fluid at one week were positive (1+ or greater growth) in 66% (38/58) of control drains compared to 21% of antisepsis drains (14/67), (p=0.0001). Drain tubing cultures demonstrated >50 CFU in 19% (8/43) of control drains versus 0% (0/53) of treated drains (p=0.004). SSI was diagnosed in 6 patients (6%) - 5 patients in the control group and 1 patient in the antisepsis group (p=0.06). Conclusions Simple and inexpensive local antiseptic interventions with a chlorhexidine disc and hypochlorite solution reduce bacterial colonization of drains. Based on these data, further study of drain antisepsis and its potential impact on SSI rate is warranted. PMID:23518704

The purpose of this study was to investigate the short-term effects of xylitol chewing gum and maltitol spray on the concentration of salivary mutans streptococci (MS) and on the plaque index. Eighty-one second, third and fourth year dental and dental assistant students with a salivary MS concentration > 103 CFU/ml cultured on mitis salivarius bacitracin (MSB) agar were included in the study. The age range of subjects was 18-23 years. The participants were divided into 3 groups: control, xylitol chewing gum and maltitol spray groups. Each subject brushed their teeth with fluoridated toothpaste (1,000 ppm). Each subject in the xylitol chewing gum group was told to chew 2 pieces, 6 times a day (total xylitol dose=7.3 g/day) for 4 weeks. Each subject in the maltitol spray group was told to spray one puff twice daily (morning and evening) for 4 weeks. A dental examination and saliva samples to determine the salivary MS concentration were collected at baseline and at 2 and 4 weeks after experiment initiation. The nonparametric Mann–Whitney U test was used to analyze differences among groups. The mean ages in the control, xylitol chewing gum and maltitol spray groups were 22±1, 20±1 and 20±1 years, respectively. The mean MS concentrations at the beginning of the study and after 2 weeks in the control, and xylitol chewing gum and moltitol oral spray groups were not significantly different from each other. There was a significantly lower MS concentration in the moltitol oral spray group than in the control group by 4 weeks (p=0.045) but no significant difference between the control group and the xylitol gum group by 4 weeks. There were no significant differences in the mean plaque index at baseline among the control group, the xylitol chewing gum group and the moltitol oral spray group. The plaque index was significantly lower in the xylitol chewing gum group than the control group (p=0.003) at 2 weeks but not 4 weeks. There was no significant difference in the mean plaque index between the control group and the moltitol oral spray group at any time. Using the maltitol spray significantly reduced the MS level in the saliva by 4 weeks use but using the xylitol gum did not. However, using the xylitol chewing gum did reduce the mean plaque by 2 weeks use but the effect did not last; by 4 weeks there was no difference from control. The moltitol spray provided no benefit over the control in reducing the mean plaque index.

Vegetables and fruits are rich in vitamins, minerals and, dietary fiber and contribute to the prevention and improvement of obesity and metabolic syndrome. However, inadequate intake of vegetable and fruit is a concern in Japan.We therefore produced a juice mixture of fresh fruit and komatsuna (Brassica rapa L. var. perviridis: B. rapa) with the aim to investigate the effects of this juice mixture on anthropometric data, blood parameters, and dietary intake differences. This study was performed as a single blind and randomized controlled trial. Subjects were 16 men (mean age, 46.4 ± 7.1 years), and they were divided into two groups (control group and intervention group). The intervention group consumed the juice mixture of fresh fruit and B. rapa. The control group consumed commercial vegetable juice. Subjects consumed juice twice a day throughout the weekday, for 4 weeks. We prepared both juices with an equivalent energy balance. Weight and body mass index (BMI) of the control group after 4 weeks were significantly increased compared with baseline values. Serum total cholesterol (T-Chol) and low-density lipoprotein cholesterol (LDL-Chol) of the intervention group after 4 weeks were significantly reduced compared with baseline values. Furthermore, intake of total vegetables and fruits were significantly increased compared with baseline values in both groups. Both vegetable juices contributed to improved intake of total vegetables and fruit. Compared with the intake of commercial vegetable juice, the intake of fresh fruit and B. rapa juice is highly effective in reducing serum cholesterol. Short-term intake of fresh fruit and B. rapa juice was shown to enhance cholesterol metabolism.

Physical symptoms (e.g., vomiting) and psychological symptoms (stress, anxiety, and depression) during pregnancy are common. Various strategies such as hypnosis are available to reduce these symptoms. The objective of the authors in this study is to investigate the impact of a hypnosis intervention in reducing physical and psychological symptoms during pregnancy. A pre-test/post-test quasi-experimental design was employed in this study. The hypnosis intervention was given to the experimental group participants at weeks 16 (baseline), 20 (time point 1), 28 (time point 2), and 36 (time point 3) of their pregnancy. Participants in the control group received only the traditional antenatal care. Participants from both groups completed the Depression Anxiety Stress Scale-21 (DASS-21) and a Pregnancy Symptoms Checklist at weeks 16, 20, 28 and 36 of pregnancy. Results indicated that stress and anxiety symptoms were significantly reduced for the experimental group, but not for the control group. Although mean differences for the depressive symptoms were not significant, the experimental group had lower symptoms at time point 3. The physical symptoms' results showed significant group differences at time point 3, indicating a reduction in the experience of physical symptoms for the experimental group participants. Our study showed that hypnosis intervention during pregnancy aided in reducing physical and psychological symptoms during pregnancy.

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.

To investigate a virtual assistance-based lifestyle intervention to reduce risk factors for Type 2 diabetes in young employees in the information technology industry in India. LIMIT (Lifestyle Modification in Information Technology) was a parallel-group, partially blinded, randomized controlled trial. Employees in the information technology industry with ≥3 risk factors (family history of cardiometabolic disease, overweight/obesity, high blood pressure, impaired fasting glucose, hypertriglyceridaemia, high LDL cholesterol and low HDL cholesterol) from two industries were randomized to a control or an intervention (1:1) group. After initial lifestyle advice, the intervention group additionally received reinforcement through mobile phone messages (three per week) and e-mails (two per week) for 1 year. The primary outcome was change in prevalence of overweight/obesity, analysed by intention to treat. Of 437 employees screened (mean age 36.2 ± 9.3 years; 74.8% men), 265 (61.0%) were eligible and randomized into control (n=132) or intervention (n=133) group. After 1 year, the prevalence of overweight/obesity reduced by 6.0% in the intervention group and increased by 6.8% in the control group (risk difference 11.2%; 95% CI 1.2-21.1; P=0.042). There were also significant improvements in lifestyle measurements, waist circumference, and total and LDL cholesterol in the intervention group. The number-needed-to-treat to prevent one case of overweight/obesity in 1 year was 9 (95% CI 5-82), with an incremental cost of INR10665 (£112.30) per case treated/prevented. A total of 98% of participants found the intervention acceptable. A virtual assistance-based lifestyle intervention was effective, cost-effective and acceptable in reducing risk factors for diabetes in young employees in the information technology industry, and is potentially scalable. © 2016 Diabetes UK.

Falls in the elderly are a major health problem. Although exercise programs have been shown to reduce the risk of falls, the optimal exercise components, as well as the working mechanisms that underlie the effectiveness of these programs, have not yet been established. To test whether the Nijmegen Falls Prevention Program was effective in reducing falls and improving standing balance, balance confidence, and obstacle avoidance performance in community-dwelling elderly people. A total of 113 elderly with a history of falls participated in this study (exercise group, n = 79; control group, n = 28; dropouts before randomization, n = 6). Exercise sessions were held twice weekly for 5 weeks. Pre- and post-intervention fall monitoring and quantitative motor control assessments were performed. The outcome measures were the number of falls, standing balance and obstacle avoidance performance, and balance confidence scores. The number of falls in the exercise group decreased by 46% (incidence rate ratio (IRR) 0.54, 95% confidence interval (CI) 0.36-0.79) compared to the number of falls during the baseline period and by 46% (IRR 0.54, 95% CI 0.34-0.86) compared to the control group. Obstacle avoidance success rates improved significantly more in the exercise group (on average 12%) compared to the control group (on average 6%). Quiet stance and weight-shifting measures did not show significant effects of exercise. The exercise group also had a 6% increase of balance confidence scores. The Nijmegen Falls Prevention Program was effective in reducing the incidence of falls in otherwise healthy elderly. There was no evidence of improved control of posture as a mechanism underlying this result. In contrast, an obstacle avoidance task indicated that subjects improved their performance. Laboratory obstacle avoidance tests may therefore be better instruments to evaluate future fall prevention studies than posturographic balance assessments. Copyright (c) 2006 S. Karger AG, Basel.

The association of the Mediterranean diet and exercise appears to have a protective role, reducing cardiovascular risk. This study investigated the effects of education sessions on the Mediterranean diet and an exercise program in modifying eating behaviors, body composition and abdominal fat. An experimental study was performed on 20 subjects with known coronary heart disease randomly assigned to experimental (n=10) and control (n=10) groups. Both groups received education sessions on the Mediterranean diet, but the experimental group also followed an eight-week program of specific exercises. A semiquantitative food frequency questionnaire was administered to analyze food intake, bioimpedance was used to measure weight, fat mass and lean mass, and waist circumference was measured to calculate waist-to-height ratio. After eight weeks, protein (p<0.05) and cholesterol (p<0.05) intake in the experimental group had decreased significantly compared with the control group. Between the beginning and end of the study, there were significant decreases in the control group in carbohydrate (p<0.05) and saturated fat intake (p<0.05). In both groups the percentage of total fat (p<0.05) and fat mass (p<0.05) was significantly decreased. In the experimental group the waist-to-height ratio was significantly reduced (p<0.05). The Mediterranean diet reduced carbohydrate and saturated fat intake, reflected in reduced fat mass. The association of the exercise program showed additional benefits in reduction of protein and cholesterol intake and abdominal fat. Copyright © 2015 Sociedade Portuguesa de Cardiologia.

Hyperbaric oxygen (HBO2) therapy has been adopted for crush injuries, but there are few studies supporting its use. We therefore investigated the effects of HBO2 on management of patients with complicated crush injuries. This historic cohort study included patients with crush injuries and open fractures with severities greater than or equal to Gustilo class IIIA. We divided the patients into two groups: Control and HBO2. The control group received conventional treatment, while the HBO2 group received conventional treatment plus HBO2. We compared the groups with respect to the incidence of infection, need for additional surgery, and length of intensive care unit (ICU) and hospital stays. There were 16 patients in the HBO2 group and 13 in the control group. There were no patients with infections in the HBO2 group, whereas in the control group six patients had infections and five needed another drainage procedure. These incidences were significantly lower in the HBO2 group (p = 0.003 and 0.013). However, the durations of ICU and hospital stays were similar across the two groups. HBO2 is effective in the management of crush injuries from the viewpoint of reducing complications and reoperations. These observations should be verified in additional studies with larger sample sizes because the patient number is limited.

To observe the activity of histone deacetylase and the mRNA expression level of HDAC1 and HDAC2 in human bone marrow mononuclear cells, which induced by hydroquinone and exposed to hydroquinone plus Trichostatin as a histone deacetylase inhibitor for 10 hours respectively. Collect the bone marrow mononuclear cells suspension,divided into control group,HQ group (3 h, 6 h, 12 h, 24 h) , HQ+TSA 10 h group and HQ 10 h group. Extract the nuclear proteins and RNA, test the activity of histone deacetylase with the colorimetric HDAC assay kit and detect the mRNA expression level of HDAC1 and HDAC2 by real-time Polymerase Chain Reaction (PCR). The HDAC activity of HQ3 h group, HQ6 h group and HQ12 h group were 1.31 times, 1.53 times and 1.148 times than that of control group respectively. And the difference was statistically significant (P<0.05). Except the HQ24 h group (P>0.05) , the HDAC1 mRNA expression of HQ3 h group, HQ6 h group and HQ12 h group were 1.173 times, 1.901 times and 2.348 times than that of control group respectively. And the difference was statistically significant (P<0.05). The HDAC2 mRNA expression of HQ6 h group and HQ12 h group were 1.426 times and 1.766 times than that of the control group respectively. And the difference was statistically significant (P<0.05). No significant difference was observed between HQ3 h group, HQ24 h group and control group (P>0.05). The cells were treated by hydroquinone plus TSA for 10 hours. The HDAC activity of HQ+TSA 10h group was reduced by 25.6% than that of HQ 10 h group (P<0.05) and rised 13.0% compared to the control group (P<0.05). And the difference was statistically significant between groups (P<0.05) .The cells were treated by hydroquinone plus TSA for 10 hours. The HDAC1 mRNA expression of the HQ+TSA 10h group is reduced by 26.9% than that of HQ10h group. The HDAC2 mRNA expression is reduced by 19.3% compared to the HQ 10h group.And the difference was statistically significant between groups (P<0.05). The HDAC1 and HDAC2 mRNA expression is obviously higher than the control group, the difference was statistically significant (P<0.05). Treatment of hydroquinone, the histone deacetylase activity and the mRNA expression of HDAC1 and HDAC2 were increased in a certain time range. The histone deacetylase inhibitor (TSA) can reduce the histone deacetylase activity and the mRNA expression level of HDAC1 and HDAC2 in the bone marrow mononuclear cell induce by hydroquinone.It can be confirmed that hematopoietic damage induced by the benzene metabolites is related to the histone acetylation modification level.

The aim of the present study was to investigate the therapeutic efficacy of fibroblast growth factor 10 (FGF10) in the promotion of healing, survival and expression of mucin in corneal epithelial cells in a rabbit dry eye model. A total of 12 healthy female New Zealand white rabbits were divided randomly into three groups. The lacrimal glands were injected with saline either alone (normal control group) or with concanavalin A (Con A), with either topical phosphate‑buffered saline (PBS; PBS control group) or 25 µg/ml FGF10 (FGF10 treatment group). Lacrimal gland inflammation, tear function, corneal epithelial cell integrity, cell apoptosis and mucin expression were subsequently assessed. Lacrimal gland tissue biopsies were performed in conjunction with histology and electron microscopy observations. Tear meniscus height (TMH) and tear meniscus area (TMA) were measured using Fourier domain‑optical coherence tomography. Tear membrane break‑up time (TBUT) was also assessed and corneal fluorescein staining was performed. The percentages of apoptotic corneal and conjunctival (Cj) epithelial cells (ECs) were counted using a terminal deoxynucleotidyl transferase‑mediated dUTP nick end labeling method. The mRNA expression levels of Muc1 were determined using reverse transcription‑quantitative polymerase chain reaction analyses. The TMH and TMA values of the PBS and treatment groups were found to be significantly reduced, compared with those of the normal control group 3 days after Con A injection. However, the TMH and TMA of the FGF10 treatment group were higher, compared with those of the PBS group 3 and 7 days after treatment, respectively. Furthermore, the FGF10 treatment group exhibited prolonged TBUT, reduced corneal fluorescein staining and repaired epithelial cell ultrastructure7 days after treatment. The percentages of apoptotic corneal‑ and Cj‑ECs in the FGF10 treatment group were significantly reduced, compared with those in the PBS group. FGF10 significantly induced the mRNA expression of Muc1 in the corneal epithelial cells, compared with the normal control group, and induced higher mRNA expression levels of Muc1 in the Cj‑ECs, compared with the PBS control group. In the present study, the rabbit dry eye model was successfully established 3 days after lacrimal gland Con A injection. FGF10 eye drops increased TMH and TMA, promoted corneal epithelial healing, reduced apoptosis of the corneal- and Cj-ECs and led to increased expression of Muc1.

Background: falls in hospitals are a major problem and contribute to substantial healthcare burden. Advances in sensor technology afford innovative approaches to reducing falls in acute hospital care. However, whether these are clinically effective and cost effective in the UK setting has not been evaluated. Methods: pragmatic, parallel-arm, individual randomised controlled trial of bed and bedside chair pressure sensors using radio-pagers (intervention group) compared with standard care (control group) in elderly patients admitted to acute, general medical wards, in a large UK teaching hospital. Primary outcome measure number of in-patient bedside falls per 1,000 bed days. Results: 1,839 participants were randomised (918 to the intervention group and 921 to the control group). There were 85 bedside falls (65 fallers) in the intervention group, falls rate 8.71 per 1,000 bed days compared with 83 bedside falls (64 fallers) in the control group, falls rate 9.84 per 1,000 bed days (adjusted incidence rate ratio, 0.90; 95% confidence interval [CI], 0.66–1.22; P = 0.51). There was no significant difference between the two groups with respect to time to first bedside fall (adjusted hazard ratio (HR), 0.95; 95% CI: 0.67–1.34; P= 0.12). The mean cost per patient in the intervention group was £7199 compared with £6400 in the control group, mean difference in QALYs per patient, 0.0001 (95% CI: −0.0006–0.0004, P= 0.67). Conclusions: bed and bedside chair pressure sensors as a single intervention strategy do not reduce in-patient bedside falls, time to first bedside fall and are not cost-effective in elderly patients in acute, general medical wards in the UK.

Aging is associated with increased levels of circulating inflammatory markers and reduced muscle mass and strength. We investigated whether intake of protein-enriched milk for 12 weeks would influence markers of inflammation among adults ≥70years of age with reduced physical strength. In a double-blind randomized controlled intervention study, subjects were randomly allocated into two groups, receiving a protein-enriched milk (2×20g protein/d, n=14, mean (±SD) age 76.9±4.9 yrs) or an isocaloric carbohydrate drink (n=17, age 77.7±4.8 yrs) for 12 weeks. We measured serum and mRNA expression levels of inflammatory markers in PBMCs. Significant differences in the mRNA expression of nuclear receptor subfamily, group H, member 3 (NR1H3, encoding the LXRα transcription factor) and interferon gamma (INFG) were observed between groups. The mRNA level of TNFRSF1A was significantly reduced, while the mRNA level of dipeptidyl-peptidase 4 (DPP4) was significantly increased, in the control group. The serum level of TNFα increased significantly in the control group, while sTNFRSF1A increased significantly in both groups, but with no significant differences between groups. Consumption of a low-fat, protein-enriched milk for 12 weeks had minor effects on inflammatory related markers in older adults compared to an isocaloric carbohydrate drink.

The prevention of hip fracture with risedronate and ergocalciferol plus calcium supplementation in elderly women with Alzheimer disease: a randomized controlled trial.

PubMed

Sato, Yoshihiro; Kanoko, Tomohiro; Satoh, Kei; Iwamoto, Jun

A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis. We previously found that deficiency of 25-hydroxyvitamin D and compensatory hyperparathyroidism cause reduced bone mineral density in female patients with AD. We address the possibility that treatment with risedronate sodium and ergocalciferol plus calcium supplementation may reduce the incidence of nonvertebral fractures in elderly women with AD. A total of 500 elderly women with AD were randomly assigned to daily treatment with 2.5 mg of risedronate sodium or a placebo, combined with 1000 IU of ergocalciferol and 1200 mg of elementary calcium, and followed up for 18 months. At baseline, patients of both groups showed 25-hydroxyvitamin D deficiency with compensatory hyperparathyroidism. During the study period, bone mineral density in the risedronate group increased by 4.1% and decreased by 0.9% in the control group. Vertebral fractures occurred in 29 patients (24 hip fractures) in the control group and 8 patients (5 hip fractures) in the risedronate group. The relative risk in the risedronate group compared with the control group was 0.28 (95% confidence interval, 0.13-0.59). Elderly patients with AD hypovitaminosis D are at increased risk for hip fracture. Treatment with risedronate and ergocalciferol may be safe and effective in reducing the risk of a fracture in elderly patients with AD.

To examine the therapeutic effect of Src inhibitor on the VEGF mediating vascular hyperpermeability and bone destruction within steroid-associated osteonecrotic lesions in rabbits. Rabbits with high risk for progress to destructive repair in steroid-associated osteonecrosis were selected according to our published protocol. The selected rabbits were systemically administrated with either Anti-VEGF antibody (Anti-VEGF Group) or Src inhibitor (Src-Inhibition Group) or VEGF (VEGF-Supplement Group) or a combination of VEGF and Src inhibitor (Supplement &Inhibition Group) or control vehicle (Control Group) for 4 weeks. At 0, 2 and 4 weeks after administration, in vivo dynamic MRI, micro-CT based-angiography, histomorphometry and immunoblotting were employed to evaluate the vascular and skeletal events in different groups. The incidence of the destructive repair in the Anti-VEGF Group, Src-Inhibition Group and Supplement &Inhibition Group was all significantly lower than that in the Control Group. The angiogenesis was promoted in VEGF-Supplement Group, Src-Inhibition Group and Supplement &Inhibition Group, while the hyperpermeability was inhibited in Anti-VEGF Group, Src-Inhibition Group and Supplement &Inhibition Group. The trabecular structure was improved in Src-Inhibition Group and Supplement &Inhibition Group. Src inhibitor could reduce permeability without disturbing vascularization and prevent destructive repair in steroid-associated osteonecrosis.

Infertility means failure to achieve pregnancy after one year of regular unprotected sexual intercourse. Infertile women may experience severe stress and depression. Numerous studies have indicated that auriculotherapy could reduce stress. Thus, the aim of the present study was to determine the effect of auriculotherapy on the stress and the outcome assisted reproductive technology in infertile women. The present study was a clinical trial that was conducted on 56 infertile women aged 20-45, who were assigned into two groups of intervention and control, from November 2014 to November 2015. The control group only received the routine treatments, while the intervention group, in addition to their routine treatment, received auriculotherapy for 8-10 sessions during menstrual cycle. Both groups completed Newton's Fertility Problem Inventory in three stages. The datasets collected for the study were analyzed using independent t -test, repeated-measures analysis of variance, and Chi-square test. The mean score of stress in the intervention group decreased significantly, compared to the control group prior to the embryo transfer and pregnancy test stages. Although insignificant, the rate of pregnancy in the intervention group was higher than the control group. There was a significant increase in the rate of clinical pregnancy in the intervention group, compared to the control. The results indicated that auriculotherapy might be effective in reducing stress and improving the outcome of assisted reproductive treatment.

By observation of the diameter, progression rate, wall thickness, and the opening angle of the abnormal aortic of abdominal aortic aneurysm (AAA) in rats, to observe the effect of saturated hydrogen saline on residual strain of AAA rats, and to investigate its inhibition effect on AAA formation. Twenty healthy male Sprague Dawley rats (weighing, 200-220 g) were randomly divided into 2 groups, which was made the AAA model by infiltration of the abdominal arota with 0.5 mol/L calcium chloride. Saturated hydrogen saline (5 mL/kg) or saline (5 mL/kg) was injected intraperitoneally in the experimental group or control group respectively, every day for 28 days. At 28 days, the diameter, progression rate, wall thickness, and opening angle of the abnormal aorta were mearsured. The aortic tissue was harvested for histological examination (HE staining and aldehyde-fuchsin staining). At 28 days after operation, the diameter of abnormal aorta in 2 groups were significantly higher than preoperative ones (P < 0.05), the progression rate in experimental group (65% +/- 15%) was significantly lower than that in control group (128% +/- 54%) (t=3.611, P=0.005). The opening angle and the wall thickness in experimental group were (88.78 +/- 29.20) degrees and (0.14 +/- 0.03) mm respectively, had significant differences when compared with the values in control group [(44.23 +/- 28.52) degrees and (0.36 +/- 0.05) mm respectively] (P < 0.01). The integrity and continuity of the aortic wall in experimental group were superior to that in the control group. Compared with the control group, the injury of elastic fiber in aortic wall and the infiltration of inflammation were all reduced. Saturated hydrogen saline can maintain good mechanical properties and reduce dilatation of the aorta by increasing residual strain and reducing the remodeling of it.

Early amniotomy is common in obstetric practice but, its effectiveness has not been proven. To determine the effects of early amniotomy on the duration of labour, and other maternal / neonatal outcomes of uncomplicated pregnancies in Enugu, South-east Nigeria. A randomized controlled study of 214 consenting term pregnant women at the University of Nigeria Teaching Hospital Enugu, Nigeria. Intervention group received amniotomy early in active labour while the control group had their membranes conserved. Mean duration of labour for the amniotomy group (279.4 ± 53.7 minutes) was significantly lower than that of control group (354.4 ± 67.5 minutes), (t = -8.988, p <0.001). Three (3.8%) women in amniotomy group needed oxytocin augmentation as against 21 (19.6%) women in the control group RR = 0.14, (CI 95%: 0.04 - 0.46), NNT = 16. The two groups did not vary with respect to cesarean section rate, newborn Apgar scores, and need for new born special care unit admission. Early amniotomy when compared to fetal membrane conservation reduced the duration of labour and need for oxytocin augmentation among term singleton pregnant women in Enugu, Nigeria. Its routine use in well selected cases may reduce prolonged labour and its complications.

Obstetric haemorrhage accounts for 20-25% of maternal mortality and morbidity. Anti-fibrinolytics are being widely used in field of surgery. It is also used to reduce heavy menstrual blood loss. To analyse the effectiveness of Tranexamic Acid (TXA) in reducing blood loss during elective caesarean section. This interventional, randomized, parallel group study was done in the Department of Obstetrics and Gynaecolgy, PSG IMSR, Coimbatore, from June 2014 to May 2015. It was conducted on 120 women undergoing caesarean section. They were allocated to either Study or Control group by computer generated random number tables. TXA was given prior to surgery in study group in addition to the routine care {10 units of oxytocin added to the intravenous drip soon after baby delivery} whereas, the control group had routine care alone. Blood loss was measured in both groups by gravimetric method. Haemoglobin before and after surgery was estimated and the percentage of difference was compared. Primary outcome variables were volume of blood loss and percentage fall in haemoglobin before and after surgery. Secondary outcomes were duration of surgery, proportion of subjects with >500ml of blood loss, need for additional uterotonics and side effects. Unpaired t-test and Chi-square test were used to compare the outcome variables. There was significant reduction in blood loss calculated from placental delivery till end of surgery: 347.17ml in study group versus 517.72ml in control group (p<0.001). Another parameter studied was the percentage of fall in haemoglobin before and after surgery and the number of subjects who had more than 10% fall in haemoglobin. 9.3% of subjects in study group and 39% of subjects in control group had more than 10% fall in haemoglobin (p<0.01). There were no immediate post-operative complications to the mother and neonate. TXA significantly reduced the amount of blood loss during Lower Segment Caesarean Section (LSCS). Use of TXA was not associated with adverse effects. Thus, TXA can be used safely and effectively in subjects undergoing LSCS.

High blood pressure is preventable and is directly related to lifestyle habits such as an unbalanced diet, low levels of physical activity, and tobacco use. This quasiexperimental study aimed to assess the effectiveness of a 3-year community intervention targeting healthy lifestyle promotion in reducing hypertension prevalence among adults. A quasiexperimental design was used to evaluate the effectiveness of a 3-year intervention for healthy lifestyle that was implemented between 2010 and 2013 in a community of adults in the region of Sousse in Tunisia. The population study was randomly selected in both intervention and control groups at pre-assessment and post-assessment. After considering a type 1 error α of 5%, a type 2 error β of 20%, and a change in the prevalence of various risk factors of 6% between pre-intervention and post-intervention, the sample size was fixed to 2,000 adults in intervention and control areas. The intervention group was composed of 940 and 1,001 adults, and the control group was composed of 940 and 976, respectively, at pre-assessment and post-assessment. The prevalence of hypertension decreased in the intervention group globally from 37.3% to 33.7% but not significantly (p = 0.1). In the control group, this proportion increased from 31.1% to 33.4% without significant difference (p = 0.28). In the intervention group, after stratification for age, a significant decrease (p = 0.007) in the prevalence of hypertension was observed for participants younger than 40 years old: it decreased from 22.8% to 16.2%. In the control group, it increased from 14% to 15.4% (p = 0.52). In intervention group, a significant decrease of the hypertension from 31.4% to 26% (p = 0.03) was observed among nonobese participants after stratification for weight status. No significant change was observed in the control group. This study showed the feasibility and effectiveness of a community-based intervention to reduce the prevalence of hypertension in the context of a developing country.

Non-attendance is a global health-care problem. The aim of the present study was 1) to investigate if a telephone reminder could reduce the non-attendance rate, 2) to study reasons for non-attendance and 3) to evaluate if a permanent implementation would be economically advantageous in a gastroenterology outpatient clinic like ours. This was a comparative intervention study with a historical control group in a gastroenterology outpatient clinic. The study lasted six months. Patients with a scheduled appointment in the first three-month period received no reminder (control group, n = 2,705). Patients in the following three-month period were reminded by telephone one weekday in advance of their appointment, when possible (intervention group, n = 2,479). Non-attending patients in the intervention group received a questionnaire. Based on the results, a financial cost-benefit analysis was made. In the intervention group, 1,577 (64%) patients answered the reminder telephone call. The non-attendance rate was significantly lower in the intervention group (6.1%) than in the control group (10.5%) (p < 0.00001). Only 1.3% of the patients who answered the reminder turned out to be non-attendees. The most common explanation for non-attendance in the intervention group was forgetfulness (39%). The reminder telephone call was cost-effective. In this outpatient clinic, telephone reminders were cost-effective and significantly reduced the non-attendance rate by 43%.

Lithospermum erythrorhizon Sieb. et Zucc. (LE) is widely used in the treatment of abnormal skin conditions, but its systemic efficacy, especially in atopic dermatitis (AD), is not clear. To examine the systemic efficacy of LE on the clinical manifestation of AD-like skin lesions, NC/Nga mice, a murine model of AD, were fed a control diet (group CA: atopic control) or a diet with a 70% ethanol extract from 5% LE (group LE) for 10 weeks. In group LE, the clinical manifestation of AD-like skin lesions was prevented as the level of serum IgE, epidermal hyperproliferation, and the number and duration of scratching episodes, which were greater in group CA, were significantly reduced to a similar level of the normal control group of BALB/c mice (group C). In addition, the level of ceramides, the major lipid maintaining the epidermal barrier, in the epidermis of group LE was increased, and was inversely associated with a decreased protein level of ceramidase, an enzyme of ceramide degradation. However, the mRNA and the protein levels of serine palmitoyl transferase (enzyme for de novo ceramide synthesis) in groups C, CA and LE did not differ. It was demonstrated that oral supplementation with LE extract prevented the development of atopic dermatitis with reducing ceramide degradation coupled with a low expression of ceramidase protein.

Cardiopulmonary bypass during cardiac surgery leads to impaired microcirculatory perfusion. We hypothesized that vascular leakage is an important contributor to microcirculatory dysfunction. Imatinib, a tyrosine kinase inhibitor, has been shown to reduce vascular leakage in septic mice. We investigated whether prevention of vascular leakage using imatinib preserves microcirculatory perfusion and reduces organ injury markers in a rat model of cardiopulmonary bypass. Male Wistar rats underwent cardiopulmonary bypass after treatment with imatinib or vehicle (n=8 per group). Cremaster muscle microcirculatory perfusion and quadriceps microvascular oxygen saturation were measured using intravital microscopy and reflectance spectroscopy. Evans Blue extravasation was determined in separate experiments. Organ injury markers were determined in plasma, intestine, kidney, and lungs. The onset of cardiopulmonary bypass decreased the number of perfused microvessels by 40% in the control group [9.4 (8.6-10.6) to 5.7 (4.8-6.2) per microscope field; P<0.001 vs baseline], whereas this reduction was not seen in the imatinib group. In the control group, the number of perfused capillaries remained low throughout the experiment, whilst perfusion remained normal after imatinib administration. Microvascular oxygen saturation was less impaired after imatinib treatment compared with controls. Imatinib reduced vascular leakage and decreased fluid resuscitation compared with control [3 (3-6) vs 12 ml (7-16); P=0.024]. Plasma neutrophil-gelatinase-associated-lipocalin concentrations were reduced by imatinib. Prevention of endothelial barrier dysfunction using imatinib preserved microcirculatory perfusion and oxygenation during and after cardiopulmonary bypass. Moreover, imatinib-induced protection of endothelial barrier integrity reduced fluid-resuscitation requirements and attenuated renal and pulmonary injury markers.

Background and Purpose— The effect of statins on progression of carotid intima–media complex thickness (IMT) has been shown exclusively in nonstroke Western patients. This study aimed to determine the effect of low-dose pravastatin on carotid IMT in Japanese patients with noncardioembolic ischemic stroke. Methods— This is a substudy of the J-STARS trial (Japan Statin Treatment Against Recurrent Stroke), a multicenter, randomized, open-label, parallel-group trial to examine whether pravastatin reduces stroke recurrence. Patients were randomized to receive pravastatin (10 mg daily, usual dose in Japan; pravastatin group) or not to receive any statins (control group). The primary outcome was IMT change of the common carotid artery for a 5-year observation period. IMT change was compared using mixed-effects models for repeated measures. Results— Of 864 patients registered in this substudy, 71 without baseline ultrasonography were excluded, and 388 were randomly assigned to the pravastatin group and 405 to the control group. Baseline characteristics were not significantly different, except National Institutes of Health Stroke Scale scores (median, 0 [interquartile range, 0–2] versus 1 [interquartile range, 0–2]; P=0.019) between the 2 groups. Baseline IMT (mean±SD) was 0.887±0.155 mm in the pravastatin group and 0.887±0.152 mm in the control group (P=0.99). The annual change in the IMT at 5-year visit was significantly reduced in the pravastatin group as compared with that in the control group (0.021±0.116 versus 0.040±0.118 mm; P=0.010). Conclusions— The usual Japanese dose of pravastatin significantly reduced the progression of carotid IMT at 5 years in patients with noncardioembolic stroke.

To investigate the efficacy of the one-piece ostomy bags for severe organophosphate poisoned patients after catharsis. Sixty cases of severe organophosphate poisoned patients who were given rhubarb catharsis after thorough nasal lavage were divided into two groups. The observation group used the one-piece ostomy bags whilst the control group used the disposable changing mats. The perineal skin changes, average daily hours of care, and cost of care rates were compared between the two groups. The rates of perineal skin changes were lower in the observation group than the control group (p < 0.05). The average daily hours of nursing and the cost of care were lower in the observation group than in the control group (p < 0.05). The application of one-piece perineal paste ostomy bag in poisoned patients after the catharsis can prevent the risk of nursing by protecting and promoting the care quality, reducing the nursing workload and improving their work efficiency. It can enhance the nurses' self-esteem, reduce patients' expenses and provide an objective basis for assessing the treatments.

Background Although a nkle injuries occur frequently in high school football players no prospective studies have been performed to determine if wearing lace-up ankle braces will reduce the incidence and severity of ankle and other lower extremity injuries in these athletes. Purpose Determine if lace-up ankle braces reduce the incidence and severity of lower extremity injuries sustained by high school football players. Design Cluster randomized controlled trial. Methods 2081 players from 50 high schools were randomly-assigned to braced or control group. Braced group subjects wore lace-up ankle braces during the 2010 football season. Athletic trainers recorded brace compliance, athletic exposures and injuries. Cox Proportional Hazards models were utilized to compare injury rates between groups. Injury severity (days lost) was tested with Wilcoxon Rank Sum. Results The rate of acute ankle injury (per 1,000 exposures) was 0.48 in the braced group compared to 1.12 in the control group (Cox Hazard Ratio (HR)=0.39, 95% Confidence Interval [CI] 0.24, 0.65, p<0.001). The severity (median days lost) of acute ankle injuries was the same (5 days) in both groups (p=0.985). The rate of acute knee injury was 0.70 in the braced group compared to 0.69 in the control group, (HR=0.92 [0.57, 1.47], p=0.721). There was no difference (p=0.242) in the severity of knee injuries between the groups (controls 11.5 days, braced =17 days. The rate of other lower extremity injuries was 0.95 in the braced group and 1.32 in the control group, (HR=0.72 [0.48, 1.09], p=0.117) while the severity was similar in both groups (6 days versus 7 days, p=0.295). Conclusions Players who used lace-up ankle braces had a lower incidence of acute ankle injuries but no difference in the incidence of acute knee or other lower extremity injuries. Braces did not reduce the severity of ankle, knee or other lower extremity injuries. PMID:21926383

Reducing patient length of stay is a high priority for health service providers. Preliminary information suggests additional Saturday rehabilitation services could reduce the time a patient stays in hospital by three days. This large trial will examine if providing additional physiotherapy and occupational therapy services on a Saturday reduces health care costs, and improves the health of hospital inpatients receiving rehabilitation compared to the usual Monday to Friday service. We will also investigate the cost effectiveness and patient outcomes of such a service. A randomised controlled trial will evaluate the effect of providing additional physiotherapy and occupational therapy for rehabilitation. Seven hundred and twelve patients receiving inpatient rehabilitation at two metropolitan sites will be randomly allocated to the intervention group or control group. The control group will receive usual care physiotherapy and occupational therapy from Monday to Friday while the intervention group will receive the same amount of rehabilitation as the control group Monday to Friday plus a full physiotherapy and occupational therapy service on Saturday. The primary outcomes will be patient length of stay, quality of life (EuroQol questionnaire), the Functional Independence Measure (FIM), and health utilization and cost data. Secondary outcomes will assess clinical outcomes relevant to the goals of therapy: the 10 metre walk test, the timed up and go test, the Personal Care Participation Assessment and Resource Tool (PC PART), and the modified motor assessment scale. Blinded assessors will assess outcomes at admission and discharge, and follow up data on quality of life, function and health care costs will be collected at 6 and 12 months after discharge. Between group differences will be analysed with analysis of covariance using baseline measures as the covariate. A health economic analysis will be carried out alongside the randomised controlled trial. This paper outlines the study protocol for the first fully powered randomised controlled trial incorporating a health economic analysis to establish if additional Saturday allied health services for rehabilitation inpatients reduces length of stay without compromising discharge outcomes. If successful, this trial will have substantial health benefits for the patients and for organizations delivering rehabilitation services.

To analyze the effects of an intervention based on the Transtheoretical Model on anthropometric and dietetic profile among women in the Primary Health Care in Brazil. Randomized controlled trial. The control group participated in physical activity and open group-education regarding nutrition of usual care. The intervention group participated in 10 workshops based on the Transtheoretical Model. Seventy-one women completed the study, with a mean age of 57.9±11.7years. Participants in the intervention group showed an improved body perception, reduced weight and body mass index post-intervention, and lower consumption of calories and foods high in fat. Significant weight reduction in the intervention group was associated with higher per capita income, reduced consumption of protein, reduced consumption of lipids, and the removal of visible fat from red meat and skin from chicken. An intervention based on the Transtheoretical Model promoted reduction in consumption of foods high in calories and fat, with positive effects on weight and body perception. These results provide evidence of the applicability and benefit of the Transtheoretical Model within primary care. Copyright © 2014 Elsevier Ltd. All rights reserved.

Blood transfusion is often required in total knee replacement; various methods of blood preservation have been studied. The best solution is to reduce the loss of blood during and after surgery. We designed this study to evaluate the hemostatic efficacy and safety of fibrin tissue adhesive (Quixil) in patients receiving total knee arthroplasty [low contact stress (LCS, DePuy, Warsaw, IN, US) cementless total knee replacement (TKR)] with a prospective, randomized, standard treatment controlled study. Thirty-five patients were randomized to receive treatment with fibrin tissue adhesive (treatment group), and 35 were randomized to be managed with postoperative blood recovery and reinfusion (control group). Blood loss in suction drain, decrease in hemoglobin values, and transfusions were recorded. A significant reduction in apparent total blood loss was detected in the treatment group compared with the control group. There was also a lower decrease in hemoglobin level, although this difference was not significant. When fibrin tissue adhesive was administered, the need for transfusions was lower. No major adverse events were recorded in our series. Fibrin tissue adhesive reduced blood loss in TKR and seemed to significantly reduce the need for blood transfusion. Fibrin tissue adhesive can be an appropriate solution to enhance hemostasis and vessel sealing at the operative site in TKR, in order to reduce blood loss after surgery and the risk of complications.

Background The aim of this study was to assess the feasibility, efficacy and safety of a modified silicone fluted drain tube after video-assisted thoracic surgery (VATS) lung resection. Methods The prospective randomized study included 50 patients who underwent VATS lung resection between March 2015 and June 2015. Eligible patients were randomized into two groups: experimental group (using the silicone fluted drain tubes for chest drainage) and control group (using standard drain tubes for chest drainage). The volume and characteristics of drainage, postoperative (PO) pain scores and hospital stay were recorded. All patients received standard care during hospital admission. Results In accordance with the exit criteria, three patients were excluded from study. The remaining 47 patients included in the final analysis were divided into two groups: experiment group (N=24) and control group (N=23). There was no significant difference between the two groups in terms of age, sex, height, weight, clinical diagnosis and type of surgical procedure. There was a trend toward less PO pain in experimental group on postoperative day (POD) 1, with a statistically significant difference. Patients in experimental group had a reduced occurrence of fever [temperature (T) >37.4 °C] compared to the control group. Conclusions The silicone fluted drain tube is feasible and safe and may relieve patient PO pain and reduce occurrence of fever without the added risk of PO complications. PMID:26941976

Polat, Hatice; Ergüney, Seher

The purpose of this study was to determine the effect of reflexology on reducing dyspnea and fatigue in patients with chronic obstructive pulmonary disease (COPD). The study was conducted as a pretest-posttest experimental design. The population of the study consisted of 60 patients (30 in experimental group and 30 in control group). Patient Description Form, Baseline Dyspnea Index (BDI) and Visual Analogue Scale-Fatigue (VAS-F) were used to collect the data. The difference between pretest-posttest dyspnea and fatigue mean scores of patients in the experimental group was statistically significant (p < .01). The difference between pretest-posttest dyspnea and fatigue mean scores of patients in the control group was statistically insignificant (p > .05). It was determined that the reflexology reduced dyspnea and fatigue in patients with COPD. Complementary methods such as reflexology should be used with pharmacological methods to reduce dyspnea and fatigue of COPD patients.

Preterm neonates undergo several painful procedures in NICU including heel prick for blood sugar monitoring. Nonpharmacological interventions have been tried to decrease this procedural pain. There are only few studies on Kangaroo mother care (KMC) in reducing pain among preterm neonates. This crossover trial was conducted at a tertiary care teaching hospital in south India. Premature Infant Pain Profile (PIPP) related to heel prick was assessed in 50 preterm neonates undergoing KMC and compared with 50 preterm babies without KMC. PIPP scores at 15 minutes and 30 minutes after heel prick were significantly less in KMC group compared to control group. Mean PIPP difference between baseline and 30 minutes after heel prick was also significantly low in KMC group compared to control group. KMC is effective in reducing pain due to heel prick among preterm babies.

Obesity, hyperglycemia and dyslipidemia, are major risk factors. However, natural therapies, dietary components, and physical activity may effect on these concerns. The aim of this study was to examine the effect of aerobic exercise and consumption of liquid ginger extract on lipid profile of Male rats with a high-fat fed diet. 32 rats were randomly divided into 4 groups: 1) aerobic exercise, 2) Ginger extract, 3) combined aerobic exercise and Ginger extract, and 4) the control. Subjects of the first three groups received ginger extract via gavage feeding of 250 mg/kg. The exercise program was 3 sessions per week on 3 different days over 4 weeks. Total cholesterol (TC), Triglyceride (TG), HDL and LDL were measured 24-h before the first session and 24-h after the final training session. The concentration of TG in the control group was significantly higher than other groups. In addition, the mean concentration of TG in the aerobic exercise group was significantly lower than Ginger extract group but there was no significant difference as compared to combined aerobic exercise and ginger extract group. The combination of aerobic exercise and ginger consumption significantly reduced the TG level compared to ginger group. TC and LDL concentrations were significantly decreased in all groups compare to control. The combination of aerobic exercise and ginger extract feeding caused a significant increase in HDL levels. The finding of this study suggests that the combination of aerobic exercise and liquid ginger extract consumption might be an effective method of reducing lipid profiles, which will reduce the risk of cardiovascular diseases caused by high-fat diets.

The analgesic efficacy of the transversus abdominis plane peripheral nerve block following abdominal tissue breast reconstruction has not been studied in a randomized controlled trial. The authors conducted a double-blind, placebo-controlled, 1:1 allocation, two-arm parallel group, superiority design, randomized controlled trial in patients undergoing microsurgical abdominally based breast reconstruction. Intraoperatively, epidural catheters were inserted under direct vision through the triangle of Petit on both sides of the abdomen into the transversus abdominis plane just before rectus fascial closure. Patients received either bupivacaine (study group) or saline (placebo group) through the catheters for 2 postoperative days. All patients received hydromorphone by means of a patient-controlled analgesic pump. The primary outcome was the difference in the parenteral opioid consumption on each postoperative day between the groups. The secondary outcome measures included the following: total in-hospital opioid; antinausea medication; pain, nausea, and sedation scores; Quality of Recovery Score; time to ambulation; and hospital stay duration. Between September of 2011 and June of 2013, 93 patients were enrolled: 49 received bupivacaine and 44 received saline. There were 11 postoperative complications (13 percent); none were related to the catheter. Primary outcomes were completed by 85 of 93 patients (91.3 percent); the mean parenteral morphine consumption was significantly reduced on postoperative day 1 in the bupivacaine group (20.7±20.1 mg) compared with 30.0±19.1 mg in the control group (p=0.02). There were no significant differences in secondary outcomes. Following abdominally based breast reconstruction, transversus abdominis plane peripheral nerve block is safe and significantly reduces morphine consumption in the early postoperative period.

Slowly digestible starch (SDS), as a functional carbohydrate providing a slow and sustained glucose release, may be able to modulate food intake through activation of the gut-brain axis. Diet-induced obese rats were used to test the effect on feeding behavior of high-fat (HF) diets containing an SDS, fabricated to digest into the ileum, as compared to rapidly digestible starch (RDS). Ingestion of the HF-SDS diet over an 11-week period reduced daily food intake, through smaller meal size, to the same level as a lean body control group, while the group consuming the HF-RDS diet remained at a high food intake. Expression levels (mRNA) of the hypothalamic orexigenic neuropeptide Y (NPY) and Agouti-related peptide (AgRP) were significantly reduced, and the anorexigenic corticotropin-releasing hormone (CRH) was increased, in the HF-SDS fed group compared to the HF-RDS group, and to the level of the lean control group. SDS with digestion into the ileum reduced daily food intake and paralleled suppressed expression of appetite-stimulating neuropeptide genes associated with the gut-brain axis. This novel finding suggests further exploration involving a clinical study and potential development of SDS-based functional foods as an approach to obesity control. © 2017 WILEY-VCH Verlag GmbH & Co.

The PREDIMED (Prevención con Dieta Mediterránea) randomized primary prevention trial showed that a Mediterranean diet enriched with either extravirgin olive oil or mixed nuts reduces the incidence of stroke, myocardial infarction, and cardiovascular mortality. We assessed the effect of these diets on the incidence of atrial fibrillation in the PREDIMED trial. Participants were randomly assigned to 1 of 3 diets: Mediterranean diet supplemented with extravirgin olive oil, Mediterranean diet supplemented with mixed nuts, or advice to follow a low-fat diet (control group). Incident atrial fibrillation was adjudicated during follow-up by an events committee blinded to dietary group allocation. Among 6705 participants without prevalent atrial fibrillation at randomization, we observed 72 new cases of atrial fibrillation in the Mediterranean diet with extravirgin olive oil group, 82 in the Mediterranean diet with mixed nuts group, and 92 in the control group after median follow-up of 4.7 years. The Mediterranean diet with extravirgin olive oil significantly reduced the risk of atrial fibrillation (hazard ratio, 0.62; 95% confidence interval, 0.45-0.85 compared with the control group). No effect was found for the Mediterranean diet with nuts (hazard ratio, 0.89; 95% confidence interval, 0.65-1.20). In the absence of proven interventions for the primary prevention of atrial fibrillation, this post hoc analysis of the PREDIMED trial suggests that extravirgin olive oil in the context of a Mediterranean dietary pattern may reduce the risk of atrial fibrillation. http://www.controlled-trials.com.

Wedged insoles are believed to be of clinical benefit to individuals with knee osteoarthritis by reducing the knee adduction moment (KAM) during gait. However, previous clinical trials have not specifically controlled for KAM reduction at baseline, thus it is unknown if reduced KAMs actually confer a clinical benefit. Forty-eight participants with medial knee osteoarthritis were randomly assigned to either a control group where no footwear intervention was given, or a wedged insole group where KAM reduction was confirmed at baseline. KAMs, Knee Injury and Osteoarthritis Outcome Score (KOOS) and Physical Activity Scale for the Elderly (PASE) scores were measured at baseline. KOOS and PASE surveys were re-administered at three months follow-up. The wedged insole group did not experience a statistically significant or clinically meaningful change in KOOS pain over three months (p=0.173). Furthermore, there was no association between change in KAM magnitude and change in KOOS pain over three months within the wedged insole group (R 2 =0.02, p=0.595). Improvement in KOOS pain for the wedged insole group was associated with worse baseline pain, and a change in PASE score over the three month study (R 2 =0.57, p=0.007). As an exploratory comparison, there was no significant difference in change in KOOS pain (p=0.49) between the insole and control group over three months. These results suggest that reduced KAMs do not appear to provide any clinical benefit compared to no intervention over a follow-up period of three months. ClinicalTrials.gov ID Number: NCT02067208.

PURPOSE Recent evidence supports a significant association between the intake of dietary fiber and levels of inflammatory markers. The objective of this study was to determine whether daily fiber supplementation would reduce levels of inflammatory markers. METHODS This study was a prospective randomized controlled trial at a single university medical center. Participants were overweight or obese adults with no history of heart disease. The intervention was psyllium supplementation at either 7 or 14 g/d for 3 months compared with no supplements in a control group. The main outcome measure was change in level of high-sensitivity C-reactive protein (hsCRP) concentration; secondary outcomes included changes in interleukin-6 (IL-6) levels, fibrinogen levels, and white blood cell (WBC) count. Protocol completers attended at least 2 visits and took more than 75% of the prescribed fiber dose. RESULTS In this intent-to-treat analysis (n = 158), there were no significant differences between either of the 2 treatment groups and the control group in the amount of change in CRP, fibrinogen, or IL-6 levels or in WBC count (P>.05). In the analysis of protocol completers (n = 132), there also were no significant differences between the groups except for a small decrease in fibrinogen level in the high-fiber group (−6 mg/dL [−0.18 μmol/L] compared with 13 mg/dL [0.38 μmol/L] in the control group, P<.05). CONCLUSION Psyllium fiber supplementation did not significantly reduce CRP levels in overweight or obese individuals in this trial, and changes in other markers were not consistent. Further research is needed to determine whether other fibers or nutrients can reduce inflammatory markers. PMID:18332401

Biased and less sensitive: A gamified approach to delay discounting in heroin addiction.

People with addiction will continue to use drugs despite adverse long-term consequences. We hypothesized (a) that this deficit persists during substitution treatment, and (b) that this deficit might be related not only to a desire for immediate gratification, but also to a lower sensitivity for optimal decision making. We investigated how individuals with a history of heroin addiction perform (compared to healthy controls) in a virtual reality delay discounting task. This novel task adds to established measures of delay discounting an assessment of the optimality of decisions, especially in how far decisions are influenced by a general choice bias and/or a reduced sensitivity to the relative value of the two alternative rewards. We used this measure of optimality to apply diffusion model analysis to the behavioral data to analyze the interaction between decision optimality and reaction time. The addiction group consisted of 25 patients with a history of heroin dependency currently participating in a methadone maintenance program; the control group consisted of 25 healthy participants with no history of substance abuse, who were recruited from the Western Sydney community. The patient group demonstrated greater levels of delay discounting compared to the control group, which is broadly in line with previous observations. Diffusion model analysis yielded a reduced sensitivity for the optimality of a decision in the patient group compared to the control group. This reduced sensitivity was reflected in lower rates of information accumulation and higher decision criteria. Increased discounting in individuals with heroin addiction is related not only to a generally increased bias to immediate gratification, but also to reduced sensitivity for the optimality of a decision. This finding is in line with other findings about the sensitivity of addicts in distinguishing optimal from nonoptimal choice options.

Background Posttraumatic stress disorder (PTSD) is often associated with impaired fear inhibition and decreased safety cue processing; however, studies capturing the cognitive aspect of inhibition and contextual cue processing are limited. In this fMRI study, the role of contextual cues in response inhibition was investigated. Methods Male medication-naive war veterans with PTSD, male control veterans (combat controls) and healthy nonmilitary men (healthy controls) underwent fMRI while performing the stop-signal anticipation task (SSAT). The SSAT evokes 2 forms of response inhibition: reactive inhibition (outright stopping) and proactive inhibition (anticipation of stopping based on contextual cues). Results We enrolled 28 veterans with PTSD, 26 combat controls and 25 healthy controls in our study. Reduced reactive inhibition was observed in all veterans, both with and without PTSD, but not in nonmilitary controls, whereas decreased inhibition of the left pre/postcentral gyrus appeared to be specifically associated with PTSD. Impaired behavioural proactive inhibition was also specific to PTSD. Furthermore, the PTSD group showed a reduced right inferior frontal gyrus response during proactive inhibition compared with the combat control group. Limitations Most patients with PTSD had comorbid psychiatric disorders, but such comorbidity is common in patients with PTSD. Also, the education level (estimate of intelligence) of participants, but not of their parents, differed among the groups. Conclusion Our findings of reduced proactive inhibition imply that patients with PTSD show reduced contextual cue processing. These results complement previous findings on fear inhibition and demonstrate that contextual cue processing in patients with PTSD is also reduced during cognitive processes, indicating a more general deficit.

Prior research has identified reduced reward-related brain activation as a promising endophenotype for the early identification of adolescents with major depressive disorder (MDD). However, it is unclear whether reduced reward-related brain activation constitutes a true vulnerability for MDD. One way of studying vulnerability is through a high-risk design. Therefore, the aim of the current study was to determine whether reward-related activation of the ventral striatum is reduced in nondepressed daughters of mothers with a history of MDD (high-risk) similarly to currently depressed adolescent girls, compared with healthy controls. By directly comparing groups with a shared risk profile during differing states, we aimed to shed light on the endophenotypic nature of reduced reward processing for adolescent depression. We compared reward-related neural activity through functional magnetic resonance imaging (fMRI) between three groups of female biological offspring (N = 52) of mothers with differential MDD status: (a) currently depressed daughters of mothers with a history of MDD (MDD group; n = 14), (b) age- and socioeconomic status (SES)-matched never-depressed daughters of mothers with a history of MDD (high-risk group; n = 19), and (c) age- and SES-matched control daughters of mothers with no past or current psychopathology in either the mother or the daughter (healthy control group; n = 19). For the outcome phase of the reward task, right-sided ventral striatum activation was reduced for both currently depressed and high-risk girls compared with healthy controls. This ventral striatal activity correlated significantly with maternal depression scores. These findings provide further evidence of aberrant functioning for the United States Department of Health & Human Services, National Institutes of Health, National Institute of Mental Health (NIMH) Research Domain Criteria (RDoC)-defined domain of positive valence systems as a vulnerability factor for MDD and a potential endophenotype for the development of depression.

A randomized, controlled fall-prevention study including 199 patients operated on for femoral neck fracture reduced inpatient falls and injuries. No statistically significant effects of the intervention program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone old people. This study evaluates whether a postoperative multidisciplinary, multifactorial fall-prevention program performed by a geriatric team that reduced inpatient falls and injuries had any continuing effect after discharge. The intervention consisted of staff education, systematic assessment and treatment of fall risk factors and vitamin D and calcium supplementation. The randomized, controlled trial with a one-year follow-up at Umeå University Hospital, Sweden, included 199 patients operated on for femoral neck fracture, aged > or = 70 years. After one year 44 participants had fallen 138 times in the intervention group compared with 55 participants and 191 falls in the control group. The crude postoperative fall incidence was 4.16/1,000 days in the intervention group vs. 6.43/1,000 days in the control group. The incidence rate ratio was 0.64 (95% CI: 0.40-1.02, p = 0.063). Seven new fractures occurred in the intervention group and 11 in the control group. A team applying comprehensive geriatric assessment and rehabilitation, including prevention and treatment of fall-risk factors, reduced inpatient falls and injuries, but no statistically significant effects of the program could be detected after discharge. It seems that fall-prevention must be part of everyday life in fall-prone elderly.

Previous research has demonstrated the efficacy of using local compression to reduce postoperative pain after third molar surgery. It has been theorized that compression reduces pain intensity through vasoconstriction. The current research tests the veracity of this vasoconstriction hypothesis by testing the impact of local epinephrine (a local vasoconstrictor) versus a control on patients' pain ratings over 7 days following surgery. Fifty patients scheduled for mandibular third molar surgery were randomly assigned to receive one cartridge of Ultracaine DS Forte (the treatment group) or one cartridge of Ultracaine DS (the control group) after surgical removal of the third molar. Participants used the visual analog scale (VAS) to provide daily ratings of pain intensity for 7 days following surgery. In addition, on day 7, the perceived effectiveness of the pain treatment was measured with the global perceived effect (GPE) scale. A quality- of-life questionnaire was also completed. A repeated-measures ANOVA indicated that the treatment group perceived significantly less pain than the control group on days 2 to 7 following surgery. In addition, 77.8% of the treatment group perceived their pain treatment to be successful, while only 69.6% of the control group reported that their pain was reduced successfully by day 7. The results of this study provide an initial proof of concept that epinephrine may have an analgesic effect on the period following third molar surgery. Further research with larger sample sizes is needed to strengthen evidence for the clinical utility of offering localized epinephrine to patients following third molar surgery.

Defining the association between excessive noise in intensive care units, sleep disturbance and morbidity, including delirium, is confounded by the difficulty of implementing successful strategies to reduce patient's exposure to noise. Active noise control devices may prove to be useful adjuncts but there is currently little to quantify their ability to reduce noise in this complex environment. Sound meters were embedded in the auditory meatus of three polystyrene model heads with no headphones (control), with headphones alone and with headphones using active noise control and placed in patient bays in a cardiac ICU. Ten days of recording sound levels at a frequency of 1 Hz were performed, and the noise levels in each group were compared using repeated measures MANOVA and subsequent pairwise testing. Multivariate testing demonstrated that there is a significant difference in the mean noise exposure levels between the three groups (p < 0.001). Subsequent pairwise testing between the three groups shows that the reduction in noise is greatest with headphones and active noise control. The mean reduction in noise exposure between the control and this group over 24 h is 6.8 (0.66) dB. The use of active noise control was also associated with a reduction in the exposure to high-intensity sound events over the course of the day. The use of active noise cancellation, as delivered by noise-cancelling headphones, is associated with a significant reduction in noise exposure in our model of noise exposure in a cardiac ICU. This is the first study to look at the potential effectiveness of active noise control in adult patients in an intensive care environment and shows that active noise control is a candidate technology to reduce noise exposure levels the patients experience during stays on intensive care.

Evidence from studies mainly in children has shown that orally administered probiotics may prevent respiratory tract infections and associated antibiotic use. We evaluated whether advice to take daily probiotics can reduce antibiotic prescribing for winter respiratory tract infections in people with asthma. We conducted a randomized controlled, parallel-group pragmatic study for participants aged 5 years and older with asthma in a UK primary care setting. The intervention was a postal leaflet with advice to take daily probiotics from October 2013 to March 2014, compared with a standard winter advice leaflet. Primary outcome was the proportion of participants prescribed antibiotics for respiratory tract infections. There were 1,302 participants randomly assigned to a control group (n = 650) or intervention group (n = 652). There was no significant difference in the primary outcome measure, with 27.7% receiving antibiotics in the intervention group and 26.9% receiving antibiotics in the control group (odds ratio = 1.04; 95% CI, 0.82-1.34). Uptake of probiotics was low, but outcomes were similar in those who accessed probiotics (adjusted odds ratio = 1.08; 95% CI, 0.69-1.69, compared with controls). We also found no evidence of an effect on respiratory tract infections or asthma exacerbations. In this pragmatic community-based trial in people with asthma, we found no evidence that advising use of winter probiotics reduces antibiotic prescribing. © 2016 Annals of Family Medicine, Inc.

Background: Growth faltering is common in rural African children and is attributed to inadequate dietary intake and environmental enteric dysfunction (EED). Objective: We tested the hypothesis that complementary feeding with cowpea or common bean flour would reduce growth faltering and EED in 6-mo-old rural Malawians compared with the control group receiving a corn-soy blend. Design: A prospective, double-blind, randomized controlled clinical trial was conducted in which children received daily feeding for 6 mo (200 kcal/d when 6-9 mo old and 300 kcal/d when 10-12 mo old). The primary outcomes were change in length-for-age z score (LAZ) and improvements in EED, as measured by percentage of lactulose excretion (%L). %L <0.2% was considered normal. Anthropometric measurements and %L through urine were compared between each legume group and the control group with Student's t test. Results: Of the 355 infants enrolled, 291 infants completed the trial, and 288 were breastfed throughout the duration of the study. Cowpea and common bean added 4.6-5.2 g protein/d and 4-5 g indigestible carbohydrate/d to the diet. LAZ and weight-for-height z score were reduced in all 3 groups from 6 to 12 mo of age. The changes in LAZ [mean (95% CI)] for the cowpea, common bean, and control groups from 6 to 9 mo were -0.14 (-0.24, -0.04), -0.27 (-0.38, -0.16), and -0.27 (-0.35, -0.19), respectively. LAZ was reduced less in infants receiving cowpea than in those receiving control food from 6 to 9 mo ( P = 0.048). The absolute value of %L did not differ between the dietary groups at 9 mo of age (mean ± SD: 0.30 ± 0.43, 0.23 ± 0.21, and 0.26 ± 0.31 for cowpea, common bean, and control, respectively), nor did the change in %L from 6 to 9 mo. Conclusion: Addition of cowpea to complementary feeding in Malawian infants resulted in less linear growth faltering.

The literature on the effects of massage therapy on neck arthritis pain is mixed depending on the dose level, and it is also based on self-report. In the present study an attempt was made to enhance the effects of weekly massage therapy by having the participants massage themselves daily. And in addition to self-reports on pain, range of motion (ROM) and the associated ROM pain were assessed before and after the first massage session and pre-post the last session one month later. Staff and faculty members at a medical school who were eligible for the study if they had neck arthritis pain were randomly assigned to a massage or a waitlist control group (N = 24 per group). The massage group received moderate pressure massages weekly by a massage therapist plus daily self-massages. The waitlist control group received the same schedule massages one month after being control subjects. The massage group showed significant short-term reductions after the first and last day massages in self-reported pain and in ROM-associated pain as well as an increase in ROM. Comparisons between the massage group (N = 23) and the control group (N = 14) on the last versus the first day data suggested significantly different changes including increased ROM and reduced ROM-associated pain for the massage group and reduced ROM and increased ROM-associated pain for the control group. These changes occurred specifically for flexion and right and left lateral flexion motions. These data highlight the importance of designing massage therapy protocols that target the most affected neck muscle groups and then assessing range of motion and related pain before and after the massage therapy. Comparisons with other studies also suggest that moderate pressure may contribute to the massage effects, and the use of daily self-massages between sessions may sustain the effects and serve as a cost-effective therapy for individuals with neck arthritis pain.

Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

People with Multiple Sclerosis (PwMS) have a high incidence of accidental falls that have a potentially detrimental effect on their daily life participation. The effect of balance specific rehabilitation on clinical balance measures and frequency of falls in PwMS was studied. A bi-centre randomised rater-blinded controlled trial. Participants in both groups received 20 treatment sessions. Participants in the intervention group received treatment aimed at improving balance and mobility. Participants in the control group received treatments to reduce limitations at activity and body function level. Primary measures were frequency of fallers (>1 fall in two months) and responders (>3 points improvement) at the Berg Balance Scale (BBS). Data was analysed according to an intention to treat approach. One hundred and nineteen participants were randomised. Following treatment frequency of fallers was 22% in the intervention group and 23% in the control group, odds ratio (OR) and (confidence limits): 1.05 (0.41 to 2.77). Responders on the BBS were 28% in the intervention group and 33% in the control group, OR = 0.75 (0.30 to 1.91). At follow up ORs for fallers and responders at BBS were 0.98 (0.48 to 2.01) and 0.79 (0.26 to 2.42), respectively. Twenty sessions 2-3 times/week of balance specific rehabilitation did not reduce fall frequency nor improve balance suggesting the need for more frequent and challenging interventions. Implications for Rehabilitation Programs for balance rehabilitation can improve balance but their effects in fall prevention are unclear. Twenty treatments sessions 2/3 times per week did not reduced frequency of falls in MS. The comparison with similar studies suggests that higher intensity of practice of highly challenging balance activities appears to be critical to maximizing effectiveness.

To evaluate the efficacy of ketamine in preventing propofol injection pain in children. Prospective, randomized, double-blinded, placebo-controlled study. University-affiliated hospital. 192 ASA physical status 1 and 2 pediatric patients. Patients were randomly assigned to 4 groups. Group S (control) received normal saline as a placebo; Group K1, Group K3, and Group K5 received 0.1 mg/kg, 0.3 mg/kg, and 0.5 mg/kg of ketamine, respectively. Fifteen seconds after the ketamine injection, patients were injected with propofol at a rate of 12 mL/min until loss-of-eyelash reflex. Pain was evaluated blindly at the time of induction using a 4-point scale: 0 = no pain, 1 = mild pain, 2 = moderate pain, and 3 = severe pain. Adverse effects were recorded. Characteristics of induction of anesthesia, such as dose of propofol and time from propofol injection to loss of consciousness (induction duration), were noted. 39 (84.8%) Group S (control) patients had pain. Pretreatment with ketamine reduced the frequency of pain significantly to 56.5%, 17.0%, and 14.9% in Groups K1, K3, and K5, respectively. Furthermore, the frequency of moderate and severe pain in Group K1 (21.8%), Group K3 (6.4%), and Group K5 (4.3%) was significantly (P < 0.001, respectively) reduced compared with Group S (76.1%). Moreover, the dose of propofol for induction in Group K5 was smaller than in Group S, Group K1, and Group K3 (P < 0.05). One patient in Group K5 had emergence agitation. Pretreatment with a small dose of ketamine (0.3 mg/kg) reduced the frequency and intensity of propofol injection pain without severe adverse effects. Copyright © 2012 Elsevier Inc.

Morinda citrifolia L. is a traditional Polynesian medicinal plant which is apparently useful for bowel disorders, skin inflammation, infection, mouth ulcers and wound healing. This study aimed to evaluate the wound-healing activity of Morinda citrifolia fruit juice in streptozotocin-induced diabetic rats. An excision wound model was used. The animals were weight-matched and placed into three groups (n = 6 per group). Group 1 animals served as normal controls, while animals in groups 2 and 3 served as diabetic controls and experimental diabetic animals respectively. All animals were anaesthetised and a full-thickness excision wound (circular area of 300 mm2 and 2 mm deep) was created. Group 3 animals were given the juice of Morinda citrifolia fruit (100 ml per kilogram of body weight) in their drinking water for 10 days. Wound area measurements were taken on days 1, 5 and 11. Blood samples were collected simultaneously for glucose measurement. Granulation tissue that had formed on the wound was excised on day 11 and processed for histological and biochemical analysis. The wound area of the Morinda citrifolia-treated group reduced by 73% (p < 0.001) when compared with the diabetic controls (63%). Significant increases in the weight of granulation tissue (p < 0.001) and hydroxyproline content (p < 0.00 1, 92.16 +/- 4.02) were observed. The protein content was moderately high. Histological studies showed that collagen was laid down faster in the experimental diabetic animals than in the normal control and diabetic control groups. Fasting blood glucose values in the diabetic experimental group had reduced by 29% (p < 0.00 1) compared with the diabetic control animals. There was a good correlation between the wound contraction rate and blood glucose values. This study demonstrates that the juice of Morinda citrifolia fruit significantly reduces blood sugar levels and hastens wound healing in diabetic rats.

To observe the effects of NADPH oxidase inhibitor diphenylene iodonium (DPI) and apocynin on the generation of reactive oxygen species (ROS) induced by p47phox and the mechanism of p47phox-induced ROS production under hyperoxic conditions. Peripheral blood mononuclear cells (PBMCs) were isolated from the peripheral blood (2 mL) of premature infants of less than 32 weeks without oxygen uptake. The isolated cells were divided into four groups, control group, hyperoxia group, hyperoxia and DPI group, hyperoxia and apocynin group. The control group was cultured in incubator with 50 mL/L CO(2) at 37°, and the other groups were cultured in 950 mL/L O(2) and 50 mL/L CO(2) mixed gas. After 48 hours, ROS was detected by Mitosox Red staining under a confocal laser scanning microscope; malondialdehyde (MDA) was measured by thiobarbituric acid colorimetry; the location and translocation rate of p47phox was observed by immunofluorescence staining; the level of p47phox protein was tested by Western blotting. Compared with the hyperoxia group, the remaining three groups showed significantly decreased ROS and MDA levels and reduced translocation rate and level of p47phox. Compared with the control group, both the hyperoxia and DPI group and the hyperoxia and apocynin group were not significantly different in the above indexes. DPI and apocynin can reduce hyperoxia-induced ROS production by decreasing the translocation and level of p47phox.

AIM: To compare rifaximin and insulin-like growth factor (IGF)-1 treatment of hyperammonemia and brain edema in cirrhotic rats with portal occlusion. METHODS: Rats with CCl4-induced cirrhosis with ascites plus portal vein occlusion and controls were randomized into six groups: Cirrhosis; Cirrhosis + IGF-1; Cirrhosis + rifaximin; Controls; Controls + IGF-1; and Controls + rifaximin. An oral glutamine-challenge test was performed, and plasma and cerebral ammonia, glucose, bilirubin, transaminases, endotoxemia, brain water content and ileocecal cultures were measured and liver histology was assessed. RESULTS: Rifaximin treatment significantly reduced bacterial overgrowth and endotoxemia compared with cirrhosis groups, and improved some liver function parameters (bilirubin, alanine aminotransferase and aspartate aminotransferase). These effects were associated with a significant reduction in cerebral water content. Blood and cerebral ammonia levels, and area-under-the-curve values for oral glutamine-challenge tests were similar in rifaximin-treated cirrhotic rats and control group animals. By contrast, IGF-1 administration failed to improve most alterations observed in cirrhosis. CONCLUSION: By reducing gut bacterial overgrowth, only rifaximin was capable of normalizing plasma and brain ammonia and thereby abolishing low-grade brain edema, alterations associated with hepatic encephalopathy.

In this rat model study we evaluated whether pretreatment with simvastatin affects the severity of acute lung injury caused by intestinal ischemia-reperfusion (I/R). Twenty-four animals were randomly allocated to three equal groups (sham, control, simvastatin). The simvastatin group was pretreated with simvastatin 10 mg x kg(-1) x day(-1) for 3 days, whereas the other groups received placebo. The simvastatin and control groups underwent 60 min of superior mesenteric artery occlusion and 90 min of reperfusion. Compared with the simvastatin group, the control group exhibited significantly more severe intestinal I/R-induced acute lung injury, as indicated by lower Pao2 and oxygen saturation (P = 0.01 and P = 0.005, respectively) and higher mean values for neutrophil infiltration of the lungs (P = 0.003), total lung histopathologic injury score (P = 0.003), lung wet-to-dry weight ratio (P = 0.009), and lung-tissue malondialdehyde levels (P = 0.016). The control and simvastatin groups had similar serum levels and similar bronchoalveolar lavage fluid levels of cytokines (interleukin-1, interleukin-6, and tumor necrosis factor-alpha) and P-selectin at all measurements, except for a significantly higher level of bronchoalveolar lavage fluid P-selectin in the control group (P = 0.006). Pretreatment with simvastatin reduces the severity of acute lung injury induced by intestinal I/R in rats.

Effect of Sex Education Programme on at-risk sexual behaviour of school-going adolescents in Ilorin, Nigeria.

Adolescents display sexual behaviours and developmental characteristics that place them at risk for Sexually Transmitted Diseases (STDs). Because young people experiment sexually and because of the consequences of indiscriminate sexual activities on the youth, there is the need to mount sex education programmes that are geared towards enlightenment and appropriate education about sex and sexuality. To determine whether Sex Education Intervention Programme would reduce at-risk sexual behaviours of school-going adolescents. Pre-test, post-test control group quasi-experimental design. A randomly selected co-educational school in Ilorin Metropolis, Nigeria. 24 school-going adolescents aged 13-19 years. Sex Education Programme (treatment group) versus Control programme (placebo). Self-reported exposure to sexually transmitted diseases, multiple sex partners, anal sex, oral sex, non use of condom. When the treatment (intervention) group was compared with the control group in an intention to treat analysis, there were significant differences in at-risk sexual behaviours of the two groups. Those in the intervention group reported less at-risk sexual behaviours than their counterparts in the control group. The treatment group evaluated the intervention programme positively and their knowledge of sexual health improved. Lack of behavioural effect on the control group could be linked to differential quality of delivery of intervention. Compared with the control group, this specially designed intervention sex education programme reduced at-risk sexual behaviour in adolescents. Based on this finding, it was recommended that sex education be introduced into the curriculum of secondary school education in Nigeria.

Temporary Assistance for Needy Families (TANF) has limited success in building self-sufficiency, and rarely addresses exposure to trauma as a barrier to employment. The objective of the Building Wealth and Health Network randomized controlled trial was to test effectiveness of financial empowerment combined with trauma-informed peer support against standard TANF programming. Through the method of single-blind randomization we assigned 103 caregivers of children under age six into three groups: control (standard TANF programming), partial (28-weeks financial education), and full (same as partial with simultaneous 28-weeks of trauma-informed peer support). Participants completed baseline and follow-up surveys every 3 months over 15 months. Group response rates were equivalent throughout. With mixed effects analysis we compared post-program outcomes at months 9, 12, and 15 to baseline. We modeled the impact of amount of participation in group classes on participant outcomes. Despite high exposure to trauma and adversity results demonstrate that, compared to the other groups, caregivers in the full intervention reported improved self-efficacy and depressive symptoms, and reduced economic hardship. Unlike the intervention groups, the control group reported increased developmental risk among their children. Although the control group showed higher levels of employment, the full intervention group reported greater earnings. The partial intervention group showed little to no differences compared with the control group. We conclude that financial empowerment education with trauma-informed peer support is more effective than standard TANF programming at improving behavioral health, reducing hardship, and increasing income. Policymakers may consider adapting TANF to include trauma-informed programming.

OBJECTIVE Tranexamic acid (TXA), a synthetic antifibrinolytic drug, has been reported to reduce blood loss in orthopedic surgery, but there have been few reports of its use in spine surgery. Previous studies included limitations in terms of different TXA dose regimens, different levels and numbers of fused segments, and different surgical techniques. Therefore, the authors decided to strictly limit TXA dose regimens, surgical techniques, and fused segments in this study. There have been no reports of using TXA for prevention of intraoperative and postoperative blood loss in posterior lumbar interbody fusion (PLIF). The purpose of the study was to evaluate the efficacy of high-dose TXA in reducing blood loss and its safety during single-level PLIF. METHODS The study was a nonrandomized, case-controlled trial. Sixty consecutive patients underwent single-level PLIF at a single institution. The first 30 patients did not receive TXA. The next 30 patients received 2000 mg of intravenous TXA 15 minutes before the skin incision was performed and received the same dose again 16 hours after the surgery. Intra- and postoperative blood loss was compared between the groups. RESULTS There were no statistically significant differences in preoperative parameters of age, sex, body mass index, preoperative diagnosis, or operating time. The TXA group experienced significantly less intraoperative blood loss (mean 253 ml) compared with the control group (mean 415 ml; p < 0.01). The TXA group also had significantly less postoperative blood loss over 40 hours (mean 321 ml) compared with the control group (mean 668 ml; p < 0.01). Total blood loss in the TXA group (mean 574 ml) was significantly lower than in the control group (mean 1080 ml; p < 0.01). From 2 hours to 40 hours, postoperative blood loss in the TXA group was consistently significantly lower. There were no perioperative complications, including thromboembolic events. CONCLUSIONS High-dose TXA significantly reduced both intra- and postoperative blood loss without causing any complications during or after single-level PLIF.

AIM: To evaluate the effect of muscovite in preventing small bowel injury induced by nonsteroidal anti-inflammatory drugs (NSAIDs). METHODS: We recruited and screened thirty-two healthy volunteers who were randomly allocated equally into two groups: an NSAID control group, who received 75 mg slow-release diclofenac, twice daily for 14 d; and an NSAID-muscovite group, who received 3 g of muscovite in addition to the 75 mg of slow-release diclofenac, twice daily for 14 d. For gastroprotection, both groups were administered 20 mg/d of the proton pump inhibitor omeprazole. All eligible subjects underwent video capsule endoscopy (CE) prior to and 14 d after treatment. RESULTS: Thirty subjects (NSAID-muscovite group, n =16; NSAID control group, n =14) finally completed the whole trail. At the baseline CE examination, no statistically significant differences between the two groups have been observed. However, after 14 d of drug treatment, a significant difference was observed in the percentage of subjects with mucosal breaks when comparing the NSAID-muscovite group with the NSAID control group. While 71.4% (10/14) of subjects in the NSAID control group had at least one mucosal break, co-administration of muscovite in the NSAID-muscovite group reduced the rate to 31.3% (5/16) (P = 0.028). Moreover, higher number of mucosal breaks was found in the NSAID control group vs that in the NSAID-muscovite group (P < 0.05). CONCLUSION: Muscovite co-therapy reduced the incidence of small intestinal injury after 14 d of diclofenac administration. PMID:25152605

To compare the additive effects of two types of non-steroidal anti-inflammatory drugs (NSAIDs), bromfenac 0.1% or ketorolac 0.45%, relative to topical steroid alone in cataract surgery. A total 91 subjects scheduled to undergo cataract operation were randomized into three groups: Group 1, pre/postoperative bromfenac 0.1%; Group 2, pre/postoperative preservative-free ketorolac 0.45%; and Group 3, postoperative steroid only, as a control. Outcome measures included intraoperative change in pupil size, postoperative anterior chamber inflammation control, change in macular thickness and volume, and ocular surface status after operation. Both NSAID groups had smaller intraoperative pupil diameter changes compared to the control group (p<0.05). There was significantly less ocular inflammation 1 week and 1 month postoperatively in both NSAID groups than the control group. The changes in central foveal subfield thickness measured before the operation and at postoperative 1 month were 4.30±4.25, 4.87±6.03, and 12.47±12.24 μm in groups 1 to 3, respectively. In the control group, macular thickness and volume increased more in patients with diabetes mellitus (DM), compared to those without DM. In contrast, in both NSAID groups, NSAIDs significantly reduced macular changes in subgroups of patients with or without DM. Although three ocular surface parameters were worse in group 1 than in group 2, these differences were not significant. Adding preoperative and postoperative bromfenac 0.1% or ketorolac 0.45% to topical steroid can reduce intraoperative miosis, postoperative inflammation, and macular changes more effectively than postoperative steroid alone.

To evaluate the impact of a dietary counseling in reducing the intake of energy-dense foods by infants. A randomized controlled trial. São Leopoldo, Brazil. Mothers and infants of a low-income-group population were randomized into intervention (n = 163) and received dietary counseling during 10 home visits, or control (n = 234) groups. Child consumption of sugar-dense (SD) and lipid-dense (LD) foods at 12 to 16 months. The effect of the intervention was expressed by relative risks and 95% confidence intervals. Poisson regression analysis was used to determine the association between exclusive breastfeeding and the energy-dense foods intake. A smaller proportion of infants from the intervention group consumed candy, soft drinks, honey, cookies, chocolate, and salty snacks. In the intervention group, there was a reduction of 40% and 50% in the proportion of infants who consumed LD and SD foods, respectively. Being breastfed up to 6 months reduced the risk for consumption of LD and SD foods by 58% and 67%, respectively. Dietary counseling to mothers may be effective in reducing the consumption of energy-dense foods among infants, and it is helpful in improving early dietary habits.

Given the dramatic increase in depression that occurs during early adolescence in girls, interventions must address the needs of girls. The authors examined whether a depression prevention program, the Penn Resiliency Program, was more effective for girls in all-girls groups than in co-ed groups. Within co-ed groups, the authors also tested whether there were greater effects for boys than for girls. Participants were 208 11- to 14-year-olds. Girls were randomly assigned to all-girls groups, co-ed groups, or control. Boys were assigned to co-ed groups or control. Students completed questionnaires on depressive symptoms, hopelessness, and explanatory style before and after the intervention. Girls groups were better than co-ed groups in reducing girls’hopelessness and for session attendance rates but were similar to co-ed groups in reducing depressive symptoms. Co-ed groups decreased depressive symptoms, but this did not differ by gender. Findings support prevention programs and suggest additional benefits of girls groups. PMID:26139955

Blood glucose changes response during and after exercise are modulated by the postabsorptive state, intensity and duration of exercise, and the level of physical fitness as well. This study focused on the idea that high-intensity interval exercise, as mini-trampoline class, can reduce blood glucose. Thus, we examined acute changes in blood glucose among trained normoglycemic adults during a mini-trampoline exercise session. Twenty-four normoglycemic adult subjects were enrolled in the study. After physical assessment they were randomly assigned to either the experimental (N.=12) or the control group (N.=12). The experimental group performed a 50-minute session of moderate-to-high intensity (70 to 85% HRmax) exercise on a mini-trampoline commonly used in fitness classes. The control group did not perform any exercise, and all procedures were otherwise similar to the experimental group. Capillary blood glucose was measured before and every 15 minutes during the exercise session. The effects of exercise on blood glucose levels (group; time; and group interaction) were estimated using a generalized estimating equation (GEE) followed by Bonferroni's post-hoc Test (P<0.05). The experimental group showed a decrease in blood glucose levels from baseline (108.7 mg/dL): 26.1% reduction (15 min; P<0.001), 24.2% (30 min; P<0.001), and 15.7% (45 min; P<0.001). Compared to the control group, blood glucose levels in the experimental group were reduced by 18.8% (15 min; P<0.001), 14.3% (30 min; P<0.001) and 6.9% (45 min; P=0.025). The study results provide good evidence that a prescribed exercise program on a mini-trampoline can be used for reducing blood glucose levels and thus can potentially control blood glucose.

Five different East Coast Fever (ECF) (Theileria parva infection) control strategies, based on tick control and/or ECF immunization, were tested in groups of traditionally managed Sanga cattle in the Central Province of Zambia over a period of 2.5 years. Two groups were kept under intensive tick control (sprayed weekly), one group immunized and one non-immunized. Two further groups were under no tick control, one group immunized and one non-immunized, while a fifth group was immunized against ECF and maintained under strategic tick control (18 sprays per year). Tick control increased milk production and weight gain but not fertility. Immunization had neither marked detrimental nor beneficial effects on the cattle productivity. The combination of strategic tick control and immunization resulted in the highest level of production and at the same time reduced the potential risk from other tick-borne diseases.

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.

Abstract Trial Design: In the double-blind, randomized, controlled trial, we aimed to evaluate the effects of compound tufuling oral liquid (CoTOL) on serum uric acid (sUA) levels and recurrence of acute gouty arthritis in intercritical and chronic gout treatment. Methods: A total of 210 patients with gout were screened from 8 hospitals to observe the sUA and acute gouty arthritis recurrence rate-reducing effects of CoTOL in intercritical and chronic gout during a 12-week treatment. We treated 139 and 71 patients with CoTOL and the placebo, respectively, and evaluated their sUA levels, acute gouty arthritis recurrence rate, and adverse events at week 0, 6, and 12. Results: Twenty-five and 12 patients in the treatment and control groups, respectively, had interrupted treatments, whereas 114 and 59 cases, respectively, completed their treatments. At the end of the 12-week treatment, the average decrease in sUA was 74.26 (95% confidence interval [CI]: 56.74–91.77 μmol/L) and 28.81 μmol/L (95% CI: 4.91–52.71 μmol/L) in the treatment and control groups, respectively (P = 0.004). The average decrease rate of sUA was 12.76% (95% CI: 9.82%–15.70%) and 4.57% (95% CI: 0.42%–8.71%) in the treatment and control groups, respectively (P = 0.004), and the gouty arthritis recurrence rate of the treatment group was lower than that of the control group (from week 6 to 12, 21.93% and 50.88% in the treatment and control group, respectively, P < 0.001; from baseline to week 12, 38.5% and 63.16%, respectively, P = 0.003). Severe adverse events were not observed in either groups, and fewer leucopenia incidences were observed in the treatment group than those in the control group (3/139 vs. 7/71, respectively, P = 0.033). Conclusion: CoTOL reduced sUA levels and effectively prevented acute arthritis recurrence in intercritical and chronic gout without serious adverse events. PMID:28296744

High work stress has been consistently associated with disturbed autonomic balance, specifically, lowered vagal cardiac control and increased sympathetic activity, which may lead to increased cardiovascular risk. Stress management procedures have been proposed to reduce autonomic dysfunctions related to work stress in different categories of workers exposed to heightened work demands, while a limited number of studies addressed this issue in managers. The present study was aimed at evaluating the effectiveness of a respiratory sinus arrhythmia (RSA) biofeedback (BF) intervention on psychological and physiological outcomes, in managers with high-level work responsibilities. Thirty-one managers leading outstanding private or public companies were randomly assigned to either a RSA-BF training (RSA-BF; N = 16) or a control group (N = 15). The RSA-BF training consisted of five weekly 45 min sessions, designed to increase RSA, whereas controls had to provide a daily stress diary once a week. After the training, managers in both groups reported reduced heart rate at rest, lower anxiety levels and improvement in health-related quality of life. More importantly, managers in the RSA-BF group showed increased vagal control (as indexed by increased RSA), decreased sympathetic arousal (as indexed by reduced skin conductance and systolic blood pressure) and lower emotional interferences, compared to managers in the control group. Results from this study showed that RSA-BF training was effective in improving cardiac autonomic balance at rest. Moreover, findings from this study underline the effectiveness of biofeedback in reducing psychophysiological negative outcomes associated with stress in managers.

Binaural beats are an auditory illusion perceived when two different pure-tone sine waves are presented one to each ear at a steady intensity and frequency. We evaluated their effectiveness in reducing preoperative anxiety in dentistry. Sixty patients (30 in each group) who were to have impacted third molars removed were studied (experimental group: 20 women and 10 men, mean (range) age 24 (18-35) years, and control group: 22 women and 8 men, mean (range) age 28 (15-47) years). All patients were fully informed about the operation preoperatively, and their anxiety recorded on a visual analogue scale (VAS). The local anaesthetic was given and the patients waited for 10minutes, during which those in the experimental group were asked to listen to binaural beats through stereo earphones (200Hz for the left ear and 209.3Hz for the right ear). No special treatment was given to the control group. In both groups anxiety was then recorded again, and the tooth removed in the usual way. The paired t test and t test were used to assess the significance of differences between groups. The degree of anxiety in the control group was unchanged after the second measurement (p=0.625), while that in the experimental group showed a significant reduction in anxiety (p=0.001). We conclude that binaural beats may be useful in reducing preoperative anxiety in dentistry. Copyright © 2017 The British Association of Oral and Maxillofacial Surgeons. Published by Elsevier Ltd.

Rice mill is one of the businesses in informal sector. From the rice milling process, ergonomic problems arise when employees work with bent position that done repeatedly to lift grain sacks to be transferred to peeler machine. This situation will affect the comfort of work, thus increasing the workload, muscle tension, and fatigue. The consequence will certainly affect the health and productivity of workers. In this study introduces ergo Tri Hita Karana (ergo THK) as an ergonomics intervention model which solves ergonomics problems of the cultural aspects of THK. The study aim is to determine the modification of working conditions based Ergo THK to reduce workload, muscle tension and fatigue. This research uses Randomized Pretest and Posttest Control Group Design experimental design. The subjects were 30 male rice mill workers with an age range of 16 until 56 years, and then divided into 15 subjects in the control group and 15 subjects in the treatment group. The results showed that the average posttest workloads in the control group are 136.950 more less 0.297 and in the treatment group are 107.60 more less 0.396. Significance analysis showed that after the two groups done their activities, the average workload significantly different p less than 0.005. The amount of reduction in the workload between the two groups was 21.43 percent. In muscle tension posttest showed that the mean score of the muscle tension in the control group was 62.67 more less 7.31 and the treatment group was 20.96 more less 2.96. Significance analysis showed that both groups mean muscle-tension results were significantly different p less than 0.005. The amount of reduction in tension between the control group and the treatment group while working was 66.55 percent. At fatigue posttest showed that the mean score of fatigue in the control group was 76.40 more less 13.51 and the treatment group was 55.53 more less 9.51. Significant analysis showed that the mean fatigue of both groups significantly different p less than 0.005. The amount of reduction in fatigue between the control group and the treatment group while working was 27.31 percent. From this study it can be concluded that the modification of the working conditions based on Ergo THK can reduce the workload by 21.43 percent, muscle tension by 66.55 percent and fatigue by 27.31 percent.

Liraglutide, an analogue of human glucagon-like peptide 1, reduces cardiovascular events in patients with type 2 diabetes; however, it has still been unknown by which mechanisms liraglutide could reduce cardiovascular events. Type 2 diabetic patients with insulin treatment were enrolled in this randomized, open-label, comparative study. Participants were randomly assigned to liraglutide plus insulin (liraglutide group) and insulin treatment (control group) at 1:1 allocation. Primary endpoint was the change in viscera fat are (VFA, cm 2 ) at 24 weeks. Liver attenuation index (LAI) measured by abdominal computed tomography, urinary albumin-to-creatinine ratio (ACR, mg/g), and C-reactive protein (CRP) levels, skeletal muscle index (SMI), and quality of life (QOL) related to diabetes treatment were also determined. Seventeen patients (8; liraglutide group, 9; control group, mean age 59 ± 13 years; 53% female) completed this study. Liraglutide treatment significantly reduced VFA at 24 weeks; whereas, SFA was unchanged. ACR, LAI, and CRP levels were significantly reduced by liraglutide at 24 weeks and there was no difference in SMI between the two groups. Changes in VFA from baseline to 24 weeks were significantly associated with those in LAI, albuminuria, and HbA1c. Liraglutide treatment significantly improved QOL scores associated with anxiety and dissatisfaction with treatment and satisfaction with treatment. No severe adverse events were observed in both groups. Our data suggest that liraglutide could reduce visceral adiposity in parallel with attenuation of hepatic fat accumulation, albuminuria and micro-inflammation and improve QOL related to diabetes care in insulin-treated patients with type 2 diabetes.

The objective of this study is to evaluate the effectiveness of a self-help coping intervention in reducing intrusive negative thoughts while waiting for cancer genetic risk information. Between August 2007 and November 2008, 1958 new referrals for cancer genetic risk assessment were invited to participate in a randomised trial. The control group received standard information. The intervention group received this information plus a written self-help coping leaflet. The primary outcome measure was the intrusion subscale of the Impact of Event Scale. The intervention significantly reduced intrusive thoughts during the waiting period in those reporting moderate baseline levels of intrusion (p = 0.03). Following risk provision, those in the intervention group reporting low and moderate intrusive worries at baseline reported less intrusive thoughts than those in the control group (p = 0.04 and p = 0.03, respectively). The intervention had no adverse impact in the sample as a whole. Participants in the intervention group with high baseline avoidance and negative affect scores were significantly more likely to remain in the study than those in the control group (p = 0.05 and p = 0.004). Findings that the intervention both reduced distress in those with moderate levels of distress and had no adverse effects following notification of cancer genetic risk suggest that this simple intervention can be implemented across a range of oncology settings involving periods of waiting and uncertainty. The intervention may also reduce the number of individuals dropping out of cancer genetic risk assessment or screening. However, those with clinically high levels of psychological distress are likely to require a more intensive psychological intervention. Copyright © 2012 John Wiley & Sons, Ltd.

The aim of this study is to ascertain the subsequent radiobiological impact of using a consensus guideline target volume delineation atlas. Using a representative case and target volume delineation instructions derived from a proposed IMRT rectal cancer clinical trial, gross tumor volume (GTV) and clinical/planning target volumes (CTV/PTV) were contoured by 13 physician observers (Phase 1). The observers were then randomly assigned to follow (atlas) or not-follow (control) a consensus guideline/atlas for anorectal cancers, and instructed to re-contour the same case (Phase 2). The atlas group was found to have increased tumor control probability (TCP) after the atlas intervention for both the CTV (p<0.0001) and PTV1 (p=0.0011) with decreasing normal tissue complication probability (NTCP) for small intestine, while the control group did not. Additionally, the atlas group had reduced variance in TCP for all target volumes and reduced variance in NTCP for the bowel. In Phase 2, the atlas group had increased TCP relative to the control for CTV (p=0.03). Visual atlas and consensus treatment guideline usage in the development of rectal cancer IMRT treatment plans reduced the inter-observer radiobiological variation, with clinically relevant TCP alteration for CTV and PTV volumes.

This study evaluated how the Hypertension Disease Management Program (HDMP) affects patient's blood pressure, knowledge, health behaviors, and use of medical services. Evaluation was performed by 2 measures, which were before and after comparison within the management group (n = 210) and comparison between the management group and control group (n = 1050) in 2005. Systolic and diastolic blood pressure of management group significantly decreased from 137.5 and 86.0 mm Hg to 131.2 and 83.8 mm Hg (P < .001, P < .01), respectively. Dieting, snack control, consumption of low-sodium meals, low-cholesterol meals, and fruits or vegetables, regular checking of blood pressure, and stress management techniques significantly increased after HDMP. However, there was no significant difference in the use of medical service between the disease management group and the control group. This study showed that the HDMP improved lifestyle and reduced blood pressure on the disease management group, but changed neither medical costs nor use of medical services. Long-term evaluation should be performed to determine if the HDMP reduce medical costs and use of medical services.

Cranial electrotherapy stimulation (CES) is used as a treatment for depression and anxiety, and as an adjunctive intervention for pain management. This prospective study investigated whether CES could decrease preoperative anxiety, the injection pain of rocuronium, postoperative pain and stress hormone levels. Female patients undergoing thyroidectomy were randomly assigned to two groups, to receive either no pretreatment (control group) or CES pretreatment. Anxiety score, withdrawal response on rocuronium injection, and pain scores at 1, 4, 12 and 24 h post surgery were evaluated. Adrenocorticotrophic hormone (ACTH), cortisol and glucose levels were measured. Patients were blinded to the treatment condition. Fifty patients entered the study (n = 25 per group). Anxiety score and withdrawal responses during rocuronium injection were significantly reduced in the CES group compared with the control group. Pain score was significantly lower in the CES group than in the control group, 1 h and 4 h post surgery. There were no significant differences in ACTH, cortisol and glucose levels. CES pretreatment appears to reduce the level of preoperative anxiety, injection pain of rocuronium and postoperative pain. However, CES pretreatment did not affect stress hormone responses.

This study investigates the treatment of non-alcoholic fatty liver disease (NAFLD) in rats with choline and fructooligosaccharide (FOS). The healthy control group received standard diet. The other three groups consisted of animals with NAFLD. Group Estr received standard diet; group Echo received standard diet plus choline (3 g/100 g diet); and group Efos received standard diet plus FOS (10 g/100 g diet). Food intake, weight, urinary nitrogen, urinary ammonia, total cholesterol, serum triacylglyceride, liver and heart weights, tissue nitrogen, tissue fat, vitamin E, TBARS, and reduced glutathione (GSH) were measured in hepatic and heart tissue. Choline and FOS treatments resulted in total mean fat reduction in liver and heart tissue of 0.2 and 1.7 g, respectively. Both treatments were equally effective in reducing hepatic and cardiac steatosis. There were no differences in the TBARS level among experimental and control groups, indicating that the proposed treatments had no added protection against free radicals. While all experimental groups had increased vitamin E and GSH levels, choline treatment led to a significant increase compared to control. PMID:25987847

Psychologic problems is increasing among pupils and has become a major problem in Sweden as well as in other Western countries. The aim of this study was to explore whether scheduled qigong exercise could have an effect on well-being at school, psychologic distress, self-image, and general stress. Pupils, 13-14 years, were assigned to either a qigong group or a control group. The qigong group had scheduled qigong 2 times a week for 8 weeks. Self-reported well-being at school, psychologic distress, self-image, and stress were measured pre- and postintervention. The control group had reduced well-being at school during the semester and the qigong group was stable. The qigong group reduced psychologic distress and stress, and had a tendency to improved self-image, whereas no changes were found in the control group. Self-image explains 47% (R(2) = 0.47) of well-being at school, and stress explains 29% (R(2) = 0.29) of psychologic distress. Scheduled qigong, meditative movement, is a possible way to improve well-being at school.

To investigate the protective effect of hydrogen against hyperoxia-induced oxidative stress injury in premature rat type II alveolar epithelial cells (AECs). The type II AECs isolated from premature rats were randomly divided into air (21% oxygen) control group, hyperoxia (95% oxygen) control group, air + hydrogen group, and hyperoxia+ hydrogen group. The cells with hydrogen treatment were cultured in the presence of rich hydrogen. After the corresponding exposure for 24 h, the cell morphology was observed microscopically. MTT assay was used to evaluated the cell proliferation ability, and JC-1 fluorescence probe was used to detect the mitochondrial membrane potential (δφ) changes of the type II AECs. The concentration of maleic dialdehyde (MDA) and superoxide dismutase (SOD) activity in the cell supernatant were detected using colorimetric method. No significant differences were found in cell growth or measurements between air control and air + hydrogen groups. Compared with air control group, the cells exposed to hyperoxia showed significantly suppressed proliferation, reduced mitochondrial membrane potential, increased MDA content, and decreased SOD activity. Intervention with hydrogen resulted in significantly increased cell proliferation and SOD activity and lowered MDA content, and restored the mitochondrial membrane potential in the cells with hyperoxia exposure (P<0.05). Hydrogen can significantly reduce hyperoxia-induced oxidative stress injury in premature rat type II AECs, improve the cellular antioxidant capacity, stabilize the mitochondrial membrane potential, and reduce the inhibitory effect of hyperoxia on cell proliferation.

High-velocity spinal manipulation is commonly adopted for treating chronic low-back pain (CLBP) and has been associated with changes in muscle activity, but the evidence is controversial. The aim of this study was to analyse the immediate effects of high-velocity spine manipulation on paraspinal activity during flexion-extension trunk movements. Forty nonspecific CLBP patients were randomised into two groups, manipulation (n = 20) and control (n = 20). While the manipulation group received high-velocity spine manipulation at the L4-L5 level, the control group remained lying in the same position. EMG-related variables, perceived pain intensity (100 mm VAS) and finger-floor distance were collected before and after spinal manipulation at the L4-L5 level. EMG surface signals from the right and left paraspinal muscles (L5-S1 level) were acquired during trunk flexion-extension cycles. EMG activity during the static relaxation phase was significantly reduced following intervention for the manipulation group but not for the control group. The extension-phase EMG activity was also reduced after manipulation, but the flexion-phase EMG levels remained unchanged. Accordingly, the percent changes in FRR and ERR were significantly larger for the manipulation group compared to the control. The results suggest that a high-velocity spinal manipulation is able to acutely reduce abnormal EMG activity during the full-flexion static phase and activation during the extension phase.

Background/aim: A third of elderly people fall each year. Poor vision is associated with increased risk of falls. The authors aimed to determine if first eye cataract surgery reduces the risk of falling, and to measure associated health gain. Methods: 306 women aged over 70, with cataract, were randomised to expedited (approximately 4 weeks) or routine (12 months wait) surgery. Falls were ascertained by diary, with follow up every 3 months. Health status was measured after 6 months. Results: Visual function improved in the operated group (corrected binocular acuity improved by 0.25 logMAR units; 8% had acuity worse than 6/12 compared with 37% of controls). Over 12 months of follow up, 76 (49%) operated participants fell at least once, and 28 (18%) fell more than once. 69 (45%) unoperated participants fell at least once, 38 (25%) fell more than once. Rate of falling was reduced by 34% in the operated group (rate ratio 0.66, 95% confidence interval 0.45 to 0.96, p = 0.03). Activity, anxiety, depression, confidence, visual disability, and handicap all improved in the operated group compared with the control group. Four participants in the operated group had fractures (3%), compared with 12 (8%) in the control group (p = 0.04). Conclusion: First eye cataract surgery reduces the rate of falling, and risk of fractures and improves visual function and general health status. PMID:15615747

In 20% of patients, capsule endoscopes fail to reach the cecum within the 8-hour battery life. This is the most common cause of incomplete small-bowel examination. The aim of this study was to determine whether keeping patients in the right lateral position (RLP) improves the complete examination rate (CER) of the small bowel by reducing the gastric transit time (GTT) of the capsule. Patients were randomized into the RLP group (n = 30) or control group (n = 30). Patients in the RLP group were instructed to lie on their right side postingestion until the capsule had passed through the pylorus. The patients in the control group were free to walk or sit (upright position). The main outcomes were the CER and GTT between the groups. There was no significant difference in the sex, mean age, and indications between the two groups. The CER was significantly higher in the RLP group than in the controls (96.7% vs. 73.3%, P = 0.030). GTT was significantly shorter in the RLP group than in the control group (medians [range]: 32 [8-108] vs. 58 [9-208] minutes, P = 0.007). Small-bowel imaging time was significantly longer in the RLP group than in the control group (372 [135-425] vs. 292 [146-422] minutes, P = 0.039). There were no significant differences in the diagnostic yields between the two groups. Placing patients in the RLP after ingestion of the capsule endoscope and before the capsule enters the pylorus is a simple method to increase the CER of the small bowel by reducing the GTT of the capsule.

The antioxidant effect of CoQ(10) on N-nitrosodiethylamine (NDEA)-induced oxidative stress was investigated in mice. Food intake and body weight were similar in both CoQ(10) and control groups during the 3-week experimental period. NDEA significantly increased the activities of typical marker enzymes of liver function (AST, ALT and ALP) both in control and CoQ(10) groups. However, the increase of plasma aminotransferase activity was significantly reduced in the CoQ(10) group. Lipid peroxidation in various tissues, such as heart, lung, liver, kidney, spleen and plasma, was significantly increased by NDEA, but this increase was significantly reduced by 100 mg/kg of CoQ(10). Superoxide dismutase activity increased significantly upon NDEA-induced oxidative stress in both the control and CoQ(10) groups with the effect being less in the CoQ(10) group. Catalase activity decreased significantly in both the control and CoQ(10) groups treated with NDEA, again with the effect being less in the CoQ(10) group. The lesser effect on superoxide dismutase and catalase in the NDEA-treated CoQ(10) group is indicative of the protective effect CoQ(10). Thus, CoQ(10) can offer useful protection against NDEA-induced oxidative stress.

Background Obesity is well associated as being an interfering factor in metabolic diseases such as hypertension and diabetes by increasing the secretion of proinflammatory markers from adipose tissue. Having healthy effects, vitamin C could work as an anti-inflammatory agent through its antioxidant capacity. Registration Registration number: FPSK_Mac [13]04. Objective The aim of the study reported here was to identify the effect of vitamin C on reducing the levels of inflammatory markers in hypertensive and/or diabetic obese adults. Subjects and methods Sixty-four obese patients, who were hypertensive and/or diabetic and had high levels of inflammatory markers, from primary health care centers in Gaza City, Palestine, were enrolled into one of two groups in an open-label, parallel, randomized controlled trial. A total of 33 patients were randomized into a control group and 31 patients were randomized into an experimental group. The experimental group was treated with 500 mg vitamin C twice a day. Results In the experimental group, vitamin C significantly reduced the levels of high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6), fasting blood glucose (FBG), and triglyceride (TG) after 8 weeks of treatment (overall: P<0.001); no changes appeared in total cholesterol (TC). In the control group, there were significant reductions in FBG and TG (P=0.001 and P=0.026, respectively), and no changes in hs-CRP, IL-6, or TC. On comparing the changes in the experimental group with those in the control group at the endpoint, vitamin C was found to have achieved clinical significance in treating effectiveness for reducing hs-CRP, IL-6, and FBG levels (P=0.01, P=0.001, and P<0.001, respectively), but no significant changes in TC or TG were found. Conclusion Vitamin C (500 mg twice daily) has potential effects in alleviating inflammatory status by reducing hs-CRP, IL-6, and FBG in hypertensive and/or diabetic obese patients. PMID:26170625

The aim of this research was to study the effect of different genistein treatments on bull sperm after thawing on pronuclear formation after in vitro fertilization (IVF) and on different sperm quality variables. Three experiments were performed. In Experiment 1, three treatments (Control, sperm incubation for 1h at 37 °C with or without genistein) and two sperm concentrations during IVF (1 or 3 × 10(6)sperm/mL) were evaluated to study the influence of genistein on pronuclear formation (PNF). Sperm incubation for 1h before IVF reduced PNF regardless of sperm concentration. However, after sperm incubation and with 3 × 10(6)sperm/mL in IVF, the genistein treatment group had greater fertilization rates than the untreated group. In Experiment 2, six treatments plus the control group were performed to study the effect of genistein (presence or not) and incubation conditions (30 min at 37 °C, 1h at 27 °C or at 37 °C) on PNF using 3 × 10(6)sperm/mL for IVF. When incubation time was reduced to 30 min, PNF rate from the genistein treatment group was no different from either the control group or in the group in which incubation occurred for 1h at 27 °C. In Experiment 3, the effect of several genistein treatments (control; genistein treatment for 30 min of incubation at 37 °C; genistein treatment for 1h of incubation at 27 °C) on sperm motility, viability and DNA fragmentation were evaluated. Genistein did not improve sperm motility and, depending on the experimental group or time, it either reduced or had no effect on sperm motility. Genistein treatment did not improve sperm viability after 5h of incubation. However, genistein treatment for 1h at 27 °C decreased sperm DNA fragmentation compared with the control group after 5h of sperm incubation. In conclusion, the treatment of bull sperm with genistein for 1h at 27 °C could decrease sperm DNA fragmentation, although PNF rate after IVF and sperm motility were reduced. Copyright © 2015.

We used herbal extracts in this study to investigate the effects of blue-light-induced oxidative stress on subjects' attentive performance, which is also associated with work performance. We employed an attention network test (ANT) to measure the subjects' work performance indirectly and used herbal extracts to reduce ocular oxidative stress. Thirty-two subjects participated in either an experimental group (wearing glasses containing herbal extracts) or a control group (wearing glasses without herbal extracts). During the ANT experiment, we collected electroencephalography (EEG) and electrooculography (EOG) data and measured button responses. In addition, electrocardiogram (ECG) data were collected before and after the experiments. The EOG results showed that the experimental group exhibited a reduced number of eye blinks per second during the experiment and faster button responses with a smaller variation than did the control group; this group also showed relatively more sustained tension in their ECG results. In the EEG analysis, the experimental group had significantly greater cognitive processing, with larger P300 and parietal 2-6 Hz activity, an orienting effect with neural processing of frontal area, high beta activity in the occipital area, and an alpha and beta recovery process after the button response. We concluded that reducing blue-light-induced oxidative stress with herbal extracts may be associated with reducing the number of eye blinks and enhancing attentive performance.

To investigate the effects of postoperative eye patching on clear corneal incision architecture in phacoemulsification. A single-center, randomized controlled trial. A total of 132 patients with uncomplicated phacoemulsification were randomly allocated to the intervention or control group. The intervention group received postoperative eye patching for approximately 18 hours, whereas the control group received eye shield. The clear corneal incision architecture was examined postoperatively at 2 hours, 1 day, and 7 days after surgery using optical coherence tomography. Epithelial gaping was significantly reduced on postoperative day 1 in the intervention group (52.4%) compared with control (74.2%) (P = 0.01). No differences were found for other architectural defects. Descemet membrane detachment was associated with lower intraocular pressure on postoperative day 7 (P = 0.02). Presence of underlying diabetes mellitus did not seem to influence architectural defects. Postoperative eye patching facilitated epithelial healing and reduced the occurrence of epithelial gaping on postoperative day 1. It may play a role in protecting and improving corneal wounds during the critical immediate postoperative period. Copyright 2017 Asia-Pacific Academy of Ophthalmology.

The objective of this study was to prospectively evaluate whether intraarticular anesthesia can reduce pain after MR or CT arthrography of the shoulder. This study included 120 patients who underwent CT or MR arthrography of the shoulder. The patients were randomized into two groups: the study group (n = 60), each administered an intraarticular injection of the contrast agent mixed with a local anesthetic (2% mepivacaine); and the control group (n = 60), each injected with the contrast agent only. Each patient's pain level was assessed at five phases-baseline and immediately, 2 hours, 1 day, and 2 days after injection-by using a visual analog scale or a verbal rating scale. The net pain score at each phase was also calculated. The pain course and net pain score were compared between study and control groups by repeated-measures analysis of variance. After the patients were divided into subgroups according to patient- or procedure-related factors, the efficacy of the intraarticular local anesthetic in each subgroup was evaluated. The pain course showed a quadratic trend and was not significantly different between study and control groups. The net pain score also was not significantly different between the two groups. No subgroup showed a significantly different efficacy of the intraarticular local anesthetic between the two groups. Intraarticular local anesthesia did not reduce arthrography-related pain.

Use of nonsteroidal anti-inflammatory drugs (NSAIDs) should be avoided in bariatric surgery patients. If use of an NSAID is inevitable, a proton pump inhibitor (PPI) should also be used. To determine the effect of an, compared to care-as-usual, additional intervention to reduce NSAID use in patients who underwent bariatric surgery, and to determine the use of PPIs in patients who use NSAIDs after bariatric surgery. A randomized controlled intervention study in patients after bariatric surgery. Patients were randomized to an intervention or a control group. The intervention consisted of sending a letter to patients and their general practitioners on the risks of use of NSAIDs after bariatric surgery and the importance of avoiding NSAID use. The control group received care-as-usual. Dispensing data of NSAIDs and PPIs were collected from patients' pharmacies: from a period of 6 months before and from 3 until 9 months after the intervention. Two hundred forty-eight patients were included (intervention group: 124; control group: 124). The number of users of NSAIDs decreased from 22 to 18 % in the intervention group and increased from 20 to 21 % in the control group (NS). The use of a PPI with an NSAID rose from 52 to 55 % in the intervention group, and from 52 to 69 % in the control group (NS). Informing patients and their general practitioners by letter, in addition to care-as-usual, is not an effective intervention to reduce the use of NSAIDs after bariatric surgery (trial number NTR3665).

This study compared the efficacy of a media literacy program and a self-esteem program designed to reduce general and specific risk factors for eating disorders. Four classes of 86 grade 8 students (53 boys and 33 girls), mean age of 13 years, were randomly assigned to either a control condition or one of the two intervention conditions. Assessment of general and specific risk factors was carried out at baseline, postintervention and 3-month follow-up. At postintervention the media literacy group had lower mean scores on weight concern than the control group (p =0.007) but the self-esteem group did not. There were some differences on self-esteem measures at the 3-month follow-up. Media literacy programs combined with an interactive, student-centered framework may potentially be a safe and effective way of reducing risk factors for eating disorders. The impact of teaching style needs to be further evaluated in prevention research. Copyright 2003 by Wiley Periodicals, Inc.

The objective of the present study was to evaluate the efficacy of combination of endovascular graft exclusion and drugs for hypertension/hyperglycemia for the treatment of abdominal aortic aneurysm (AAA). We analyzed 156 patients with AAA. Eighty-four patients were hypertensive and 72 were hyperglycemic. After endovascular graft exclusion, hypertensive patients were divided into four groups and treated with cyclopenthiazide, reserpine, propranolol, and placebo respectively. Hyperglycemic patients were divided into three groups and treated with metformin, insulin, and placebo respectively. Body temperature and peripheral blood leukocytes were measured at day 1, 2, 7, and 14 after endovascular graft exclusion. Size of AAAs, blood pressure, and blood sugar were measured again after 1 year. In hypertensive patients, the size of AAAs reduced after endovascular graft exclusion, while the combined treatments with cyclopenthiazide, reserpine, or propranolol helped to reduce blood pressure (blood pressure decrease <10 mmHg (18/21), <10 mmHg (12/21), <10 mmHg (8/21), and <10 mmHg (10/21) in the control group, cyclopenthiazide group, reserpine group, and propranolol group, respectively. AAA size decreased in the control group (P<0.001) and in the other three groups (P<0.0001). Similar results were obtained in hyperglycemic patients. The size of AAAs reduced after endovascular graft exclusion. Combined treatment with Metformin and Insulin reduced blood sugar (control, blood sugar >7.8 mmol/L (22/24), AAA size (P<0.001); metformin, blood sugar >7.8 mmol/L (14/24), AAA size (P<0.0001); insulin, blood sugar >7.8 mmol/L (11/24), AAA size (P<0.0001). Combination of endovascular graft exclusion with medicine is more effective than the former treatment alone for AAA therapy.

Ischaemia/reperfusion (I/R) injury of the lungs contributes to pulmonary dysfunction after cardiac surgery with cardiopulmonary bypass (CPB), leading to increased morbidity and mortality of patients. This study investigated the value of controlled lung reperfusion strategies on lung ischaemia-reperfusion injury in a porcine CPB model. Pigs were subjected to routine CPB for 120 min with 60 min of blood cardioplegic cardiac arrest (CCA). Following CCA, the uncontrolled reperfusion (UR, n = 6) group was conventionally weaned from CPB. Two groups underwent controlled lung reperfusion strategies (CR group: controlled reperfusion conditions, n = 6; MR group: controlled reperfusion conditions and modified reperfusate, n = 6) via the pulmonary artery before CPB weaning. Sham-operated pigs (n = 7) served as controls. Animals were followed up until 4 h after CPB. Pulmonary function, haemodynamics, markers of inflammation, endothelial injury and oxidative stress as well as morphological lung alterations were analysed. CPB (UR group) induced deterioration of pulmonary function (lung mechanics, oxygenation index and lung oedema). Also, controlled lung reperfusion groups (CR and MR) presented with pulmonary dysfunction after CPB. However, compared with UR, controlled lung reperfusion strategies (CR and MR) improved lung mechanics and reduced markers of oxidative stress, but without alteration of haemodynamics, oxygenation, inflammation, endothelial injury and lung morphology. Both controlled reperfusion groups were similar without relevant differences. Controlled lung reperfusion strategies attenuated a decrease in lung mechanics and an increase in oxidative stress, indicating an influence on CPB-related pulmonary injury. However, they failed to avoid completely CPB-related lung injury, implying the need for additional strategies given the multifactorial pathophysiology of postoperative pulmonary dysfunction. © The Author 2014.

X-ray screening of gastric cancer is broadly used in Japan, although no controlled trial has proved its effectiveness. This study evaluates the impact of an X-ray screening demonstrative intervention to reduce gastric cancer mortality in a Costa Rican region. The evaluation follows a quasi-experimental, community-controlled design, with measures before and after. About 7000 individuals participated by invitation in the two-wave screening programme. X-ray screening was followed by videoendoscopy and gastric biopsies. Treatment included resection with or without lymph node dissection. Comparisons with two control groups estimate that gastric cancer mortality was halved in the period from 2 to 7 years after the first screening visit. Validity of X-rays as used in this intervention had 88% sensitivity, 80% specificity, and 3% predictive value for individuals with two screening visits. Incidence in the screened group increased up to four times. Case survival was 85% in the intervention group after 5 years, compared to 12% among the controls before the intervention and 35% among the controls in the same region after the intervention. Although X-ray mass screening seems able to reduce stomach cancer mortality, its high cost may be an obstacle for scaling up this intervention in a non-rich country like Costa Rica. PMID:17912238

In this research, it has been aimed to evaluate the improvement effects of alpha lipoic acid (ALA), ascorbic acid-6-palmitate (AA6P), fish oil (FO), and their combination (COM) on some biochemical properties in erythrocytes of streptozotocin (STZ)-induced diabetic male rats. According to experimental results, glutathione (GSH) level in erythrocytes decreased in diabetes (P < 0.01), D + ALA, and D + AA6P groups (P < 0.001). Malonaldehyde (MA) level increased in diabetes (P < 0.05), D + FO, and D + COM groups (P < 0.001), but its level in D + AA6P and D + ALA groups was lower in diabetes group (P < 0.01). Total lipid level in diabetes and diabetes plus antioxidant administered groups were higher than control. Total cholesterol level was high in diabetes and D + ALA groups (P < 0.05), but its level reduced in D + FO compared to control and diabetes groups, P < 0.05, < 0.001, respectively. Total triglyceride (TTG) level was high in the D + ALA (P < 0.05) and D + COM (P < 0.001) groups. In contrast, TTG level in blood of diabetes group was higher than diabetes plus antioxidant and FO administered groups (P < 0.001). According to gas chromatography analysis results, while the palmitic acid raised in diabetes group (P < 0.05), stearic acid in D + FO, D + ALA, and diabetes groups was lower than control (P < 0.05), oleic acid reduced in D + COM and D + FO groups, but its level raised in D + AA6P and D + ALA groups (P < 0.01). As the linoleic acid (LA) elevated in ALA + D, D + AA6P, and diabetes groups, linolenic acid level in diabetes, D + AA6P, and D + FO groups was lower than control (P < 0.001). Arachidonic acid (AA) decreased in D + ALA, D+ AA6P, and diabetes groups (P < 0.01), but its level in D + COM and D + FO was higher than control (P < 0.05). Docosahexaenoic acid (DHA) increased in D + AA6P and D + COM (P < 0.05). While the total saturated fatty acid level raised in diabetes group, its level reduced in D + ALA and D + FO groups (P < 0.05). In contrast, total unsaturated fatty acid level in D + ALA and D + FO groups was higher than control (P < 0.05). In conclusion, present data have confirmed that the combination of the ALA, AA6P, and FO have improvement effects on the recycling of GSSG to reduced GSH in erythrocytes of diabetic rats, and in addition to this, oxidative stress was suppressed by ALA and AA6P, and unsaturated fatty acid degree was raised by the effects of ALA and FO.

Systemic lidocaine has analgesic and anti-inflammatory effects. The purpose of this prospective, randomized, double-blind study was to evaluate the effects of intravenous lidocaine on pain following thyroidectomy. Fifty-eight adult patients scheduled for total thyroidectomy were randomly allocated to receive a 1.5 mg/kg lidocaine bolus followed by a 2 mg/kg/h infusion during surgery, or the same volume of normal saline (control). After thyroidectomy, we evaluated postoperative pain, nausea, fentanyl consumption, frequency of pushing the button (FPB) for patient-controlled analgesia (PCA), High-sensitivity C-reactive protein (hs-CRP) in serum, and patient satisfaction scores regarding the recovery process. Postoperative pain and nausea scores were significantly lower in the lidocaine group for the first 4 h following thyroidectomy, compared to the control group. Fentanyl consumption and FPB for the PCA were also significantly reduced in the lidocaine group for 4 h following thyroidectomy, and hs-CRP was significantly less in the lidocaine group at postoperative days 1 and 3. Furthermore, satisfaction scores were significantly higher in the lidocaine group compared to the control group. Intravenous lidocaine effectively reduced postoperative pain and nausea following thyroidectomy as well as improved the quality of recovery. Clinicaltrials.gov NCT01608360.

Students often miss school because of gastrointestinal and respiratory illnesses. We assessed the effectiveness of a multifactorial intervention, including alcohol-based hand-sanitizer and surface disinfection, in reducing absenteeism caused by gastrointestinal and respiratory illnesses in elementary school students. We performed a school-based cluster-randomized, controlled trial at a single elementary school. Eligible students in third to fifth grade were enrolled. Intervention classrooms received alcohol-based hand sanitizer to use at school and quaternary ammonium wipes to disinfect classroom surfaces daily for 8 weeks; control classrooms followed usual hand-washing and cleaning practices. Parents completed a preintervention demographic survey. Absences were recorded along with the reason for absence. Swabs of environmental surfaces were evaluated by bacterial culture and polymerase chain reaction for norovirus, respiratory syncytial virus, influenza, and parainfluenza 3. The primary outcomes were rates of absenteeism caused by gastrointestinal or respiratory illness. Days absent were modeled as correlated Poisson variables and compared between groups by using generalized estimating equations. Analyses were adjusted for family size, race, health status, and home sanitizer use. We also compared the presence of viruses and the total bacterial colony counts on several classroom surfaces. A total of 285 students were randomly assigned; baseline demographics were similar in the 2 groups. The adjusted absenteeism rate for gastrointestinal illness was significantly lower in the intervention-group subjects compared with control subjects. The adjusted absenteeism rate for respiratory illness was not significantly different between groups. Norovirus was the only virus detected and was found less frequently on surfaces in intervention classrooms compared with control classrooms (9% vs 29%). A multifactorial intervention including hand sanitizer and surface disinfection reduced absenteeism caused by gastrointestinal illness in elementary school students. Norovirus was found less often on classroom surfaces in the intervention group. Schools should consider adopting these practices to reduce days lost to common illnesses.

In the present era, delinquency in children and adolescents is undoubtedly a difficult and upsetting issue attracting the attention of many experts such as psychologists, sociologists, and criminologists. These experts often try to answer why a number of children and adolescents engage in various crimes such as aggressive and anti-social crimes. They also try to find out how these crimes can be prevented. The present study investigates the effectiveness of mindfulness-based cognitive therapy training (MBCT) in reducing aggression in a juvenile correction and rehabilitation center of Zahedan province during years 1991 to 1992. This experimental study included an experimental and a control group with a pretest, posttest, and follow-up approach. The Buss and Perry aggression questionnaire (1992) was used for data collection. The sample group included 22 (10 experimental and 12 control groups) adolescent males in a juvenile correction and rehabilitation center of Zahedan province who were selected through a census method. Using a matching method based on the pre-test scores of the aggression questionnaire, they were then divided into two equivalent categories and were randomly assigned to the two groups. Mindfulness-based cognitive training took the group training in 8 sessions administered on experimental group. The follow-up test was conducted two weeks after the end of the posttest sessions. The results were analyzed using ANCOVA. The results of ANCOVA showed that mindfulness-based cognitive training could significantly reduce aggression during posttest and follow-up test phases in the experimental group, compared to the control group (P < 0.01). Moreover, the results indicated the effectiveness of this method in significantly reducing anger, physical aggression, and hostility during posttest and follow-up test phases (P < 0.05). However, no significant reduction was observed in the verbal aggression subscale. According to the results of the present study, mindfulness-based cognitive training seems to be effective for reducing aggressive behaviors.

This study aimed to assess the efficacy of a brief cognitive-behavioral program that was designed to reduce the work-related stress levels of secondary school teachers. A quasi-experimental design was used to compare the intervention groups with the wait-list control groups. Seventy teachers from the intervention groups and 54 from the control groups completed a set of validated scales at the baseline and 3-4 wk later. The scales included the Depression Anxiety Stress Scale, the Dysfunctional Attitude Scale-Form A, the Health-Promoting Lifestyle Profile II, and the Occupational Stress Inventory Revised Edition. After controlling for the baseline measures, the intervention groups had significantly lower role stress, personal strain and overall work-related stress 3-4 wk after the baseline measurements. The intervention groups also had significantly higher stress management behaviors, and less general stress and dysfunctional thoughts than the control groups (all p≤0.05). The levels of dysfunctional thoughts and stress management behaviors significantly predicted general stress after intervention and personal resource deficits. The level of dysfunctional thoughts also predicted the personal strain of work-related stresses (all p<0.05). The brief program reported in this study was efficacious in reducing the work-related stress of secondary teachers. Teachers experienced less work-related stress after the program, and they reported reduced dysfunctional thoughts and enhanced stress management behaviors. This program may be considered as an initial strategy for teachers to develop skills to cope with their work-related stress in the short term and could be incorporated with other strategies to achieve longer-term effects.

A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis. We previously found that vitamin K deficiency and low 25-hydroxyvitamin D (25-OHD) with compensatory hyperparathyroidism cause reduced bone mineral density (BMD) in female patients with AD. This may modifiable by intervention with menatetrenone (vitamin K2) and risedronate sodium; we address the possibility that treatment with menatetrenone, risedronate and calcium may reduce the incidence of nonvertebral fractures in elderly patients with AD. A total of 231 elderly patients with AD were randomly assigned to daily treatment with 45 mg of menatetrenone or a placebo combined with once weekly risedronate sodium, and followed up for 12 months. At baseline, patients of both groups showed high undercarboxylated osteocalcin (ucOC) and low 25-OHD insufficiency with compensatory hyperparathyroidism. During the study period, BMD in the treatment group increased by 5.7% and increased by 2.1% in the control group. Nonvertebral fractures occurred in 15 patients (10 hip fractures) in the control group and 5 patients (2 hip fractures) in the treatment group. The relative risk in the treatment group compared with the control group was 0.31 (95% confidence interval, 0.12-0.81). Elderly AD patients with hypovitaminosis K and D are at increased risk for hip fracture.

This experimental study aimed to evaluate the effects of a group music intervention on anxiety and agitation of institutionalized older adults with dementia. A total of 60 participants were randomly assigned to an experimental or a control group. The experimental group received a 30-min music intervention using percussion instruments with familiar music in a group setting in mid afternoon twice weekly for 6 weeks, whereas the control group received usual care with no music intervention. The Rating of Anxiety in Dementia scale was used to assess anxiety, and Cohen-Mansfield Agitation Inventory was used to assess agitation at baseline, week 4 and week 6. Repeated measures analysis of covariance indicated that older adults who received a group music intervention had a significantly lower anxiety score than those in the control group while controlling for pre-test score and cognitive level (F = 8.98, p = 0.004). However, the reduction of agitation between two groups was not significantly different. Anxiety and agitation are common in older adults with dementia and have been reported by caregivers as challenging care problems. An innovative group music intervention using percussion instruments with familiar music as a cost-effective approach has the potential to reduce anxiety and improve psychological well-being of those with dementia.

Tinnitus is a subjective sensation of hearing a sound in the absence of an external stimulus, which significantly worsens the quality of life in 15-25% of affected individuals. To assess the effectiveness of acupuncture therapy for tinnitus. Randomized clinical trial ( 2T9T7Q) with 50 participants with tinnitus, divided into two groups: 25 participants in the acupuncture group and 25 participants in the control group. The acupuncture group received acupuncture treatment and the control group received no treatment. After a period of 5 weeks, they were called to perform the final evaluation and the control group received acupuncture treatment for ethical reasons. A statistically significant result was found for the primary outcome, reducing the intensity of tinnitus, with p=0.0001 and the secondary endpoint, showing improvement in quality of life, with p=0.0001. Chinese scalp acupuncture associated with bilateral electroacupuncture demonstrated, in the short term, a statistically significant improvement by reducing the level of tinnitus intensity, as well as improving the quality of life of individuals with tinnitus.

Pirfenidone was administered to sensitized Brown Norway rats prior to a series of ovalbumin challenges. Airway hyperresponsiveness, inflammatory cell infiltration, mucin and collagen content, and the degree of epithelium and smooth muscle staining for TGF-beta were examined in control, sensitized, and sensitized/challenged rats fed a normal diet or pirfenidone diet. Pirfenidone had no effect on airway hyperresponsiveness, but reduced distal bronchiolar cell infiltration and proximal and distal mucin content. Statistical analysis showed that the control group and sensitized/challenged pirfenidone diet group TGF-beta staining intensity scores were not significantly different from isotype controls, but that the staining intensity scores for the sensitized/challenged normal diet group was significantly different from isotype controls. These results suggest that pirfenidone treatment is effective in reducing some of the components of acute inflammation induced by allergen challenge.

We investigated the therapeutic effects of an extract of Psidium guajava (guava) leaf on experimentally induced osteoarthritis in guinea pig. The left knee of 30 male guinea pigs was anesthetized and the cranial cruciate ligament was severed. The animals were followed for 8 weeks until osteoarthritis was confirmed by radiography and histopathology. Animals were divided randomly into five groups; group 1, the ligament was severed and untreated; group 2, the ligament was severed and treated with piascledine, an extract of soybean and avocado; group 3, the ligament was severed and treated with 200 mg/kg hydroethanolic extract of guava; group 4, the ligament was severed and treated with 400 mg/kg hydroethanolic extract of guava; and group 5, control animals without surgery or extracts. Radiological and histopathological evaluations after 8 weeks showed reduced severity of osteoarthritis in the piascledine treatment group compared to group 1. The guava extract also reduce the severity of osteoarthritis compared to controls. Histopathological examination of treatment and control groups showed that treatment the guava extract improved lesions significantly. Hydroethanolic extracts of guava leaf appears to prevent osteoarthritis by inhibition of free radical formation in the knee joint.

To investigate the mechanism of BVT.2733 on insulin resistance, by using diet-induced obese (DIO) mice model. After having been balanced for 3 days, the C57BL/6J mice were randomly divided into a normal diet group and a high-fat diet (HFD) group. After 20 weeks, the obese mice were further randomly divided into an obese control group, a BVT.2733 group and a pioglitazone (PGZ) group and they were orally administered with placebo, BVT.2733 and PGZ separately for two weeks. Adiponectin and leptin mRNA expression levels from adipose tissue were analyzed with real-time quantitative PCR. The levels of plasma glucose, serum insulin and adiponectin were measured with biochemical technology, radioimmunoassay and ELISA. Adipocyte sizes were observed with immunohistochemistry. The body weight, plasma glucose and serum insulin levels raised (P < 0.05) in the HFD group and the adipocyte sizes were bigger. Serum insulin levels significantly reduced (P < 0.05) and adipocyte sizes reduced, while plasma adiponectin level raised (P < 0.01) in the two treatment groups as compared with those in obese controls. Both the mRNA expressions of adiponectin and leptin upregulated (P < 0.05) in the PGZ group, but their expressions in the BVT.2733 group did not alter significantly. The body weight of the mice reduced significantly in the BVT.2733 group. BVT.2733 can reduce body weight significantly and improve insulin resistance, but cannot influence the expression of adipocytokines.

A pilot study examined the effectiveness of a biofeedback mouse in reducing upper extremity pain and discomfort in office workers; in addition, relative mouse use (RMU), satisfaction and the feasibility of running a randomised controlled trial (RCT) in a workplace setting were evaluated. The mouse would gently vibrate if the hand was idle for more than 12 s. The feedback reminded users to rest the arm in neutral, supported postures. Analysis showed a statistically significant reduction in shoulder pain and discomfort for the intervention group at T2 (38.7% lower than controls). Statistically significant differences in RMU time between groups were seen post intervention (-7% at T1 and +15% at T2 for the intervention group). Fifty-five percent of the intervention group was willing to continue using the mouse. It appears feasible to perform an RCT for this type of intervention in a workplace setting. Further study including more participants is suggested. The study findings support the feasibility of conducting randomised control trials in office settings to evaluate ergonomics interventions. The intervention resulted in reduced pain and discomfort in the shoulder. The intervention could be a relevant tool in the reduction of upper extremity musculoskeletal disorder. Further research will better explain the study's preliminary findings.

Despite advances in the field of intravenous therapy, phlebitis is still a common complication of peripheral venous catheter and finding an appropriate solution to prevent and reduce the incidence of this complication remains challenging. One of the methods used in reducing the incidence of phlebitis is the use of saline lock, which is forgotten in most hospitals. Therefore, this study aimed to evaluate its impact on the incidence and severity of phlebitis. In a single-blind (the researcher) clinical trial, 88 patients with peripheral venous catheter admitted in cardiac care units in selected hospitals of Isfahan University of Medical Sciences, Iran, were selected through convenient sampling method. They were randomly divided into two groups of intervention and control groups using random number table. The intervention group received 3 ml of 0.9% normal saline sterilized before and after each intravenous drug or every 12 h. However, in the control group, the intravenous drugs were given as routine and saline lock was not used. The evaluation of intravenous catheter regarding the incidence of phlebitis and its degrees using Jackson's Visual Infusion Phlebitis Scale was performed 6 times within 72 h (every 12 h). Results were evaluated by SPSS software using descriptive statistics, Chi-square test, t-test, and Mann-Whitney test. Results showed that there was a statistically significant difference between the two groups regarding the degree of phlebitis (P = 0.003). The percentage of phlebitis incidence in the control group was 88.6% and in the intervention group was 43.2%. There was a statistically significant difference between the two groups (P < 0.001). The risk of incidence of phlebitis in the group without saline lock (control), compared to the intervention group, was 10.3 times greater (CI = 95%). The incidence of phlebitis in both groups increased with increase in the duration of catheter placement. The results of this study showed that the use of saline lock in the intervention group compared to the control group, in which saline lock was not used, can have a significant impact on reducing the incidence of phlebitis and its degree.

The recently introduced Navigator® (GE Healthcare, Helsinki, Finland) and SmartPilot® View (Dräger Medical, Lübeck, Germany) show the concentrations and predicted effects of combined anesthetic drugs, and should facilitate more precisely their titration. Our aim was to evaluate if Navigator® or SmartPilot® View guided anesthesia was associated with a good quality of analgesia, depth of hypnosis and may reduce anesthetic requirements. We performed a prospective non-randomized study. Sixty ASA I-II patients undergoing balanced general anesthesia for abdominal and plastic surgery were enrolled. Patients were divided in 4 groups. Group 1 (N. 15) and group 3 (N. 15) were cases in whom anesthesia was performed with standard monitoring plus the aid of Navigator® (Nav) or SmartPilot® View (SPV) display. Group 2 (N. 15) and group 4 (N. 15) were controls in whom anesthesia was performed with standard monitoring (heart rate, NIBP, SpO2, end-tidal CO2, end-expired sevoflurane concentration, train of four, Bispectral Index [Aspect Medical Systems, Natick, MA, USA] or Entropy [GE Healthcare]). Patients' vital parameters and end-expired sevoflurane concentration were recorded during anesthesia. All patients recovered uneventfully and showed hemodynamic stability. End-tidal sevoflurane concentrations values [median (min-max)], during maintenance of anesthesia, were significantly (P<0.05) lower in SPV [1.1% (0.8-1.5)] and Nav [1%(0.8-1.8)] groups compared to SPV-control group [1.5%(1-2.5)] and Nav-control group [1.5%(0.8-2)]. BIS and entropy values were respectively higher in the SPV group [53 (46-57)] compared to the control group [43 (37-51)] (P<0.05) and Nav group [53 (43-60)] compared to the control group [41 (35-51)] (P<0.05). No significant differences in Remifentanil dosing were observed in the four groups. Navigator® and SmartPilot® View may be of clinical use in monitoring adequacy of anesthesia. Both displays can optimize the administration and monitoring of anesthetic drugs during general anesthesia and may reduce the consumption of volatile anesthetic agents.

A combination of radio-frequency (RF) and ultrasound cavitation (UC) has been reported to reduce indices of obesity. In this study, we aimed to investigate the effect of a combination of these techniques on anthropometric indices, pro-oxidant-antioxidant balance (PAB), and serum high-sensitivity C-reactive protein (hs-CRP). This randomized clinical trial was performed on 50 healthy women between January 2014 and June 2014 in Ghaem Hospital, Mashhad, Iran. Participants were randomized to one of two groups, both of which received a low-calorie diet containing 500-kcal energy deficit per day. The trial group included twenty-five subjects who were assigned to the combined treatment of RF and ultrasound cavitation program of abdomen and flank areas. There were twenty-five control subjects who received the low calorie diet alone. Biochemical markers, including serum hs-CRP and PAB values, and anthropometric indices were measured in the intervention group and healthy controls. For both the intervention and control groups, waist circumference was reduced significantly by 3.76 ± 1.69 and 2.40 ± 1.04, respectively (P < 0.05). In addition, abdominal circumference was reduced by 9.5 ± 2.66 and 3.12 ± 1.88, in these groups, respectively (P < 0.001). Decrement of PAB level in the intervention group, and its increment in the control group, were not significant (P > 0.05). In addition, reductions of hs-CRP and PAB between the two studied groups during five weeks of study were not significant (P > 0.05). Although there were significant reductions in anthropometric indices following treatment with RF and UC, the effects on serum PAB or hs-CRP were no significantly different, compared to the control group. Further studies are needed to confirm the beneficial effect for the use of these techniques.

We examined whether a positive intervention (i.e. granting a wish) could promote positive psychological and physical changes (e.g. reduced nausea and pain) in seriously-ill children. Children and their parent were randomly assigned to a wish group (completed measures 2-3 days before the wish and 3 weeks later) or to a waiting-list control group (with an equivalent time-lag and receiving the wish after the assessment). Wish intervention significantly increased levels of positive emotions, satisfaction with life, personal strengths, and reduced rates of nausea compared with the control group. Mothers in the wish group also perceived positive changes in children's benefit finding and quality of life. © The Author(s) 2015.

A randomized controlled trial of two formats of a program (Women Take PRIDE) to enhance management of heart disease by patients was conducted. Older women (N = 575) were randomly assigned to a group or self-directed format or to a control group. Data regarding symptoms, functional health status, and weight were collected at baseline and at 4, 12, and 18 months. The formats produced different outcomes. At 18 months, the self-directed format was better than the control in reducing the number (p ≤ .02), frequency (p ≤ .03), and bothersomeness (p ≤ .02) of cardiac symptoms. The self-directed format was also better than the group format in reducing symptom frequency of all types (p ≤ .04). The group format improved ambulation at 12 months (p ≤ .04) and weight loss at 18 months (p ≤ .03), and group participants were more likely to complete the program (p ≤ .05). The availability of different learning formats could enhance management of cardiovascular disease by patients. © 2014 Society for Public Health Education.

To determine the feasibility, safety, and efficacy of a home-based exercise intervention targeting fall risk in older adults with multiple sclerosis. A randomized controlled pilot trial. A home-based exercise program. Participants were randomly allocated to either a home-based exercise intervention group (n = 13) or a waiting list control group (n = 14). The exercise group completed exercises targeting lower muscle strength and balance three times a week for 12 weeks. The control group continued normal activity. Fall risk (Physiological Profile Assessment scores), balance (Berg Balance Scale), and walking testing prior to and immediately following the 12-week intervention. Each outcome measure was placed in an analysis of covariance with group as the between-subject factor and baseline values as the covariate. Effect sizes were calculated. Twelve participants from the control group and ten from the exercise group completed the study. There were no related adverse events. Fall risk was found to decrease in the exercise group following the intervention (1.1 SD 1.0 vs. 0.6 SD 0.6) while there was an increase in fall risk in the control group (1.9 SD 1.5 vs. 2.2 SD 1.9). Effect sizes for most outcomes were large (η(2) > 0.15). Home-based exercise was found to be feasible, safe, and effective for reducing physiological fall risk in older adults with multiple sclerosis. Our findings support the implementation of a larger trial to reduce fall risk in persons with multiple sclerosis.

To evaluate the efficacy of Piezosurgery in split teeth extractions. A single-center, randomized, split-mouth study was performed using a consecutive serious of unrelated healthy patients attending the departing of oral and maxillofacial surgery, Peking University School and Hospital of Stomatology. 40 patients were selected for extraction of maxillary molars without reservation value,splitting or nonvital teeth. They were divided into control (20 patients) and test groups (20 patients) randomly. Surgical treatments for both groups were under local anesthesia. Molar teeth of control group were extracted by common equipments like dental elevators, chisels, forceps, etc. While molar teeth of experimental group were extracted by Piezosurgery, aided with the use of common equipments if needed. Then we compared the duration of surgery, frequency of the usage of chisels, expansion of postoperative bony socket surgical discomfort and postoperative pain between two groups. The average of operation time was (629.5±171.0) s in control group and (456.0±337.2) s in test group. The buccal alveolar bone reduced (1.07±0.64) mm in control group and (1.49±0.61) mm in test group. There was a significant difference between the two groups (P<0.05). The duration of surgery for experimental group was significantly longer than that of the control group, but the change of buccal alveolar bone was lower than the control group. For visual analogue scale (VAS) value of surgical discomfort, expansion of postoperative bony socket and the operative fear rate, there were no significant difference between the two groups (P>0.05). Piezosugery can be better to preserve alveolar bone, reduce trauma and patient's fear. Application of the piezosugery reflect the characteristics of minimally invasive extraction, which has the value of promotion. The Piezosurgery technique have the advantage of reducing change of buccal alveolar bone during the surgery, but a longer surgical time was required when compared with the conventional technique. VAS value of surgical discomfort, expansion of postoperative bony socket and the operative fear rate, there were no significant difference. Minimally invasive tooth extraction technique has good clinical results and high satisfaction. Piezosurgery proved its worth as the instrument adapted to limiting the destruction of bone tissue.

Persistent proteinuria is an important factor contributing to the progression of diabetic nephropathy. The present randomized double-blind placebo-controlled multicenter clinical study evaluated the efficacy and safety of telmisartan combined with the antioxidant probucol in reducing urinary protein levels in patients with type 2 diabetes (T2D). Patients with T2D and 24-h proteinuria 0.5-3 g were enrolled in the study and randomly assigned to one of two groups: a telmisartan or a probucol + telmisartan group. Both groups were given telmisartan 80 mg q.d. for 48 weeks. The probucol + telmisartan group was given probucol 500 mg b.i.d. for the first 24 weeks, with the dosage then reduced to 250 mg b.i.d. for the remaining 24 weeks. The telmisartan group was given probucol placebo. In all, 160 patients were enrolled in the present study. The 24-h proteinuria levels were significantly reduced in the probucol + telmisartan compared with telmisartan group. For patients with baseline 24-h proteinuria levels <1.0 g, both treatments resulted in significant reductions in 24-h proteinuria levels after 48 weeks treatment. However, in patients with baseline 24-h proteinuria levels ≥1.0 g, 24-h proteinuria levels after 48 weeks treatment were only reduced in the probucol + telmisartan group. There was no significant difference between the two groups for either adverse cardiovascular or other events. In patients with diabetic nephropathy, probucol combined with telmisartan more effectively reduces urinary protein levels than telmisartan alone. © 2015 The Authors.

The present studies aimed to contribute to the literature on psychological variables involved in reducing red meat consumption (RMC). Study 1 investigated whether the theory of planned behaviour (TPB), plus healthy-eating and meat-eating identities, could explain intentions to reduce RMC. Study 2 evaluated the effectiveness of an SMS text message intervention on self-monitoring to reduce RMC. In Study 1, data were collected daily using online food diaries for one week and a TPB questionnaire. Study 2 was a randomised controlled trial assessing pre- and post-RMC and TPB constructs by online food diaries and questionnaires over a one-week period. Participants were Italian undergraduates in each study (Study 1: N = 405; Study 2: N = 244). In Study 2, participants were randomly allocated to control and message condition groups. Participants in the message condition group received a daily SMS, which reminded them to monitor RMC, while participants in the control group did not receive any message. Only students who completed all measures were considered in the analyses (Study 1: N = 342; Study 2: N = 228). Study 1 showed that affective and instrumental attitudes, perceived behavioural control, and meat-eating identity explained intentions to reduce RMC, while subjective norm, past behaviour, and healthy-eating identity did not. Study 2 showed that an SMS intervention was effective in increasing intentions and reducing RMC. Mediation analyses indicated partial serial mediation through healthy-eating and meat-eating identities and intentions. The present studies provide support for the predictive validity of TPB in explaining intentions to reduce RMC and for the efficacy of an SMS intervention targeting self-monitoring in reducing RMC. Findings confirmed the important role of eating identities in explaining intentions to reduce RMC and in changing this behaviour. Copyright © 2017 Elsevier Ltd. All rights reserved.

An effective intervention program aiming to reduce whole body vibration (WBV) exposure at work will reduce the number of low back complaints in the near future. An evaluation study with a controlled pretest-post-test design. Nine companies and 126 drivers were included in the study. Cluster randomization on company level divided the drivers and their employers in an intervention group and a "care-as-usual" group. At baseline (T0) and intervention program was implemented and evaluated after 7 months (T1). The main outcome measure was WBV exposure. Process measures included knowledge, attitude, and (intended) behavior towards reduction of WBV exposure for the drivers and knowledge and WBV policy for the employers. At T1, no significant reduction was found in WBV exposure within both groups compared with T0. Probably due to poor to moderate compliance, the intervention program was not effective in reducing the WBV exposure on group level but small reductions in WBV exposure are possible when intervention compliance is high.

To test the effectiveness of a theoretically based text-message intervention to reduce binge drinking among socially disadvantaged men. A multi-centre parallel group, pragmatic, individually randomized controlled trial. Community-based study conducted in four regions of Scotland. A total of 825 men aged 25-44 years recruited from socially disadvantaged areas who had two or more episodes of binge drinking (> 8 UK units on a single occasion) in the preceding 28 days: 411 men were randomized to the intervention and 414 to the control. A series of 112 interactive text messages was delivered by mobile phone during a 12-week period. The intervention was structured around the Health Action Process Approach, a comprehensive model which allows integration of a range of evidence-based behaviour change techniques. The control group received 89 texts on general health, with no mention of alcohol or use of behaviour change techniques. The primary outcome measure was the proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) at 12 months post-intervention. The proportion of men consuming > 8 units on three or more occasions (in the previous 28 days) was 41.5% in the intervention group and 47.8% in the control group. Formal analysis showed that there was no evidence that the intervention was effective [odds ratio (OR) = 0.79, 95% confidence interval (CI) = 0.57-1.08; absolute reduction 5.7%, 95% CI = -13.3 to 1.9]. The Bayes factor for this outcome was 1.3, confirming that the results were inconclusive. The retention was high and similar in intervention (84.9%) and control (86.5%) groups. Most men in the intervention group engaged with the text messages: almost all (92%) replied to text messages and 67% replied more than 10 times. A theoretically based text-messaging intervention aimed at reducing binge drinking in disadvantaged men was not found to reduce prevalence of binge drinking at 12-month follow-up. © 2018 The Authors.

The effect of glutamine therapy on outcomes in critically ill patients: a meta-analysis of randomized controlled trials

PubMed Central

2014-01-01

Introduction Glutamine supplementation is supposed to reduce mortality and nosocomial infections in critically ill patients. However, the recently published reducing deaths due to oxidative stress (REDOX) trials did not provide evidence supporting this. This study investigated the impact of glutamine-supplemented nutrition on the outcomes of critically ill patients using a meta-analysis. Methods We searched for and gathered data from the Cochrane Central Register of Controlled Trials, MEDLINE, Elsevier, Web of Science and ClinicalTrials.gov databases reporting the effects of glutamine supplementation on outcomes in critically ill patients. We produced subgroup analyses of the trials according to specific patient populations, modes of nutrition and glutamine dosages. Results Among 823 related articles, eighteen Randomized Controlled Trials (RCTs) met all inclusion criteria. Mortality events among 3,383 patients were reported in 17 RCTs. Mortality showed no significant difference between glutamine group and control group. In the high dosage subgroup (above 0.5 g/kg/d), the mortality rate in the glutamine group was significantly higher than that of the control group (relative risk (RR) 1.18; 95% confidence interval (CI), 1.02 to 1.38; P = 0.03). In 15 trials, which included a total of 2,862 patients, glutamine supplementation reportedly affected the incidence of nosocomial infections in the critically ill patients observed. The incidence of nosocomial infections in the glutamine group was significantly lower than that of the control group (RR 0.85; 95% CI, 0.74 to 0.97; P = 0.02). In the surgical ICU subgroup, glutamine supplementation statistically reduced the rate of nosocomial infections (RR 0.70; 95% CI, 0.52 to 0.94; P = 0.04). In the parental nutrition subgroup, glutamine supplementation statistically reduced the rate of nosocomial infections (RR 0.83; 95% CI, 0.70 to 0.98; P = 0.03). The length of hospital stay was reported in 14 trials, in which a total of 2,777 patients were enrolled; however, the patient length of stay was not affected by glutamine supplementation. Conclusions Glutamine supplementation conferred no overall mortality and length of hospital stay benefit in critically ill patients. However, this therapy reduced nosocomial infections among critically ill patients, which differed according to patient populations, modes of nutrition and glutamine dosages. PMID:24401636

Ionizing radiation is an integral part of percutaneous coronary angiographies. Chronic exposure to low-dose radiation confers a risk for skin damage, eye lens opacities or cataracts, and malignant diseases to staff in the catheter laboratory. The RADPAD is a sterile surgical drape that reduces the effect of scatter radiation on the operator. We sought to assess the efficacy of RADPAD shields in reducing radiation dose experienced by operators during routine diagnostic coronary angiography. Sixty consecutive patients due to undergo elective coronary angiography were randomized in a 1:1 pattern to have their procedures performed with and without the RADPAD drape in situ. Dosimetry was performed on the left arm of the primary operator. There was no significant difference in the two main determents of radiation exposure in both groups: the screening times (102 ± 86 s for the RADPAD group vs. 105 ± 36 s for the control group, p = 0.9) and body mass index (BMI; 27.7 ± 4.2 kg/m 2 for the RADPAD group vs. 27.9 ± 5.5 kg/m 2 for the control group, p = 0.8). Moreover, there was no difference in the dose-area ratio (1337 ± 582 cGy/cm 2 for the RADPAD group vs. 1541 ± 804 cGy/cm 2 for the control group, p = 0.3) between the two patient groups. The primary operator radiation dose was significantly lower in the RADPAD group at 8.0 µSv (Q1: 3.2, Q3: 20.1) compared with 19.6 µSv (Q1: 7.1, Q3: 37.7) for the control group (p = 0.02). The RADPAD significantly reduces radiation exposure to primary operators during routine diagnostic coronary angiography in patients with a BMI > 25 kg/m 2 . It reduces total radiation exposure to primary operators by 59%, and the radiation exposure rate by 47%.

If variation in procedure times could be controlled or better predicted, the cost of surgeries could be reduced through improved scheduling of surgical resources. This study on the impact of similar consecutive cases on the turnover, surgical, and procedure times tests the perception that repeating the same manual tasks reduces the duration of these tasks. We hypothesize that when a fixed team works on similar consecutive cases the result will be shorter turnover and procedure duration as well as less variation as compared with the situation without a fixed team. Case-control study. St Franciscus Hospital, a large general teaching hospital in Rotterdam, the Netherlands. Two procedures, inguinal hernia repair and laparoscopic cholecystectomy, were selected and divided across a control group and a study group. Patients were randomly assigned to the study or control group. Preparation time, surgical time, procedure time, and turnover time. For inguinal hernia repair, we found a significantly lower preparation time and 10 minutes less procedure time in the study group, as compared with the control group. Variation in the study group was lower, as compared with the control group. For laparoscopic cholecystectomy, preparation time was significantly lower in the study group, as compared with the control group. For both procedures, there was a significant decrease in turnover time. Scheduling similar consecutive cases and performing with a fixed team results in lower turnover times and preparation times. The procedure time of the inguinal hernia repair decreased significantly and has practical scheduling implications. For more complex surgery, like laparoscopic cholecystectomy, there is no effect on procedure time.

This randomized controlled clinical study aimed to determine the effect of 2 foot massage methods on symptom control in people with colorectal cancer who received chemoradiotherapy. Data were collected between June 16, 2015, and February 10, 2016, in the Department of Radiation Oncology of an oncology training and research hospital. The sample comprised 60 participants. Data were collected using an introductory information form, common terminology criteria for adverse events and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires C30 and CR29. Participants were randomly allocated to 3 groups: classical foot massage, reflexology, and standard care control. The classical massage group received foot massage using classical massage techniques, and the reflexology group received foot reflexology focusing on symptom-oriented reflexes twice a week during a 5-week chemoradiotherapy treatment schedule. The control group received neither classical massage nor reflexology. All patients were provided with the same clinic routine care. The classical massage was effective in reducing pain level and distension incidence while foot reflexology was effective in reducing pain and fatigue level, lowering incidence of distension and urinary frequency and improving life quality. © 2017 John Wiley & Sons Australia, Ltd.

Bacteria entering the bloodstream via translocation from the gastrointestinal tract spread hematogenously and can trigger bacterial chondronecrosis with osteomyelitis (BCO) by infecting osteochondrotic microfractures in the epiphyseal-physeal cartilage of the proximal femora and tibiae. In experiment 1, broilers were fed control feed or the same feed containing BacPack 2X, which includes the prebiotic IMW50 (a mannan oligosaccharide beta-glucan yeast cell wall product) plus the probiotic Calsporin (Bacillus subtilis C-3102). Broilers reared on wire flooring consistently developed higher incidences of BCO than hatchmates reared on wood shavings litter (≥24 vs. ≤4%, respectively; P=0.001). Adding BacPack 2X to the feed on d 1 through 56 delayed the age of onset and reduced the cumulative incidence of BCO on wire flooring when compared with broilers fed the control feed (24.0 vs. 40.7%, respectively; P=0.003). In experiment 2, broilers reared on wire flooring received tap water on d 1 through 62 (control group) or therapeutic levels of the potent fluoroquinolone antimicrobial enrofloxacin in the water on d 35 through 54 (enrofloxacin group). During enrofloxacin administration, half as many birds developed BCO in the enrofloxacin group when compared with the control group (8.1 vs. 19.5%, respectively, on d 35 through 54; P=0.001), whereas both groups had similar BCO incidences subsequent to withdrawing enrofloxacin on d 55 through 62 (14.8 vs. 18.2% for the enrofloxacin vs. control groups; P=0.386). Cumulative lameness incidences for d 1 through 62 were higher for the control group than for the enrofloxacin group (39.0 vs. 25.8%, respectively; P=0.003). These results demonstrate that wire flooring imposes a rigorous challenge that leads to high incidences of BCO that can be difficult to suppress, even with therapeutic doses of enrofloxacin. Prophylactically adding BacPack 2X to the feed reduced the incidence of BCO lameness by a proportion similar to that achieved with enrofloxacin, indicating that probiotics potentially can provide effective alternatives to antibiotics for reducing BCO lameness attributable to bacterial translocation and hematogenous distribution. © 2015 Poultry Science Association Inc.

Background Weight gain early after transplant is a risk factor for posttransplant metabolic syndrome (PTMS), cardiovascular events, and renal insufficiency. The impact of mammalian target of rapamycin inhibition on posttransplant weight gain and the development of PTMS components postliver transplantation were examined in a randomized, controlled study. Methods After a run-in period, patients (N = 719) were randomized at 30 ± 5 days posttransplant in a 1:1:1 ratio to 3 treatment groups: (i) everolimus (EVR) + reduced tacrolimus (TAC) (n = 245); (ii) TAC control (n = 243) or (iii) TAC elimination (n = 231). In this post hoc analysis, weight change at 12 and 24 months was compared between groups. Vital signs, lipids, and laboratory parameters at 12 and 24 months and rates of PTMS were assessed. Results Mean increase in weight from baseline was higher at month 12 in the TAC control arm (8.15 ± 9.27 kg) than in the EVR + reduced TAC (5.88 ± 12.60 kg, P = 0.056) and the TAC elimination arms (4.76 ± 9.94 kg, P = 0.007). At month 24, the TAC control arm displayed a significantly greater weight increase (9.54 ± 10.21 kg) than either the EVR + reduced TAC (6.69 ± 8.37 kg, P = 0.011) or the TAC elimination groups (6.01 ± 9.98 kg, P = 0.024). Rates of PTMS were similar for the EVR + reduced TAC (71.8%), TAC elimination (70.3%) and TAC control (67.4%) arms (P = NS). Conclusions EVR with reduced-exposure TAC attenuated weight gain at 1 and 2 years posttransplant compared with a standard TAC immunosuppression regimen. Rates of PTMS were comparable between EVR-containing and TAC control regimens. PMID:28817434

To observe the effects of electroacupuncture (EA) with branch-foundation acupoint combination on the indices regarding pituitary-target gland axis in aging rats with yang deficiency, so as to explore its regulating mechanism on aging rats with yang deficiency. Forty healthy Sprague-Dawley female rats were randomly divided into a normal control group, a model group, an EA group and an EA control group, 10 rats in each group. Except the normal control group, the rats in the rest 3 groups were all treated with subcutaneous injection of D-galactose for 40 d, followed by intramuscular injection of hydrocortisone for 7 d to establish aging model with yang deficiency. After the successful establishment of model, the EA group was treated with EA at "Guanyuan" (CV 4), "Housanli" (ST 36) and "Baihui "(GV 20) while the EA control group was treated with EA at "Zhongji" (CV 3) "Yinlingquan" (SP 9) and "Yintang" (GV 29); the rats in the normal control group and model group were immobilized and fixed during the same time period. The treatments were given 6 times per week totally for 4 weeks. With radiation immunity analysis method, the 8 biological indices of pituitary-target gland axis, including thyroid-stimulating hormone (TSH), triiodothyronine (T3), tetraiodothyronine-4 (T4), adrenocorticotropic hormone (ACTH), corticosterone (CORT), estradiol (E2), luteinizing hormone (LH) and follicle-stimulating hormone (FSH) were detected to observe the changes of their content. Compared with the normal control group, the serum level of TSH, T3, T4 and E2 were reduced in the model group (P<0.05, P< 0.01) while those of ACTH, CORT, FSH and LH were increased (P<0.05, P<0.01). Compared with the model group, the serum level of TSH, T3, T4 and E2 were increased in the EA group (P<0.05, P<0.01) while those of ACTH, CORT, FSH and LH were significantly reduced (P<0.05, P<0.01). Compared with the EA control group, the content of TSH was increased in the EA group without statistical significance (P>0.05), that of T3, T4 and E2 was increased (all P<0.05) and that of ACTH, CORT, FSH and LH was significantly reduced (all P<0.05). The electroacupuncture with branch-foundation acupoint combination has benign regulating effects on the key hormones of pituitary-target gland axis, which could effectively improve the dysfunction of pituitary-target gland axis that is caused by aging with yang deficiency; the efficacy of electroacupuncture with branch-foundation acupoint combination is superior to that of adjacent control acupoint combination.

What is the effect of mime therapy on facial symmetry and severity of paresis in people with facial nerve paresis? Randomised controlled trial. 50 people recruited from the Outpatient department of two metropolitan hospitals with facial nerve paresis for more than nine months. The experimental group received three months of mime therapy consisting of massage, relaxation, inhibition of synkinesis, and co-ordination and emotional expression exercises. The control group was placed on a waiting list. Assessments were made on admission to the trial and three months later by a measurer blinded to group allocation. Facial symmetry was measured using the Sunnybrook Facial Grading System. Severity of paresis was measured using the House-Brackmann Facial Grading System. After three months of mime therapy, the experimental group had improved their facial symmetry by 20.4 points (95% CI 10.4 to 30.4) on the Sunnybrook Facial Grading System compared with the control group. In addition, the experimental group had reduced the severity of their paresis by 0.6 grade (95% CI 0.1 to 1.1) on the House-Brackmann Facial Grading System compared with the control group. These effects were independent of age, sex, and duration of paresis. Mime therapy improves facial symmetry and reduces the severity of paresis in people with facial nerve paresis.

The time-left procedure was designed to evaluate the psychophysical function for time. Although previous results indicated a linear relationship, it is not clear what role the observed bias toward the time-left option plays in this procedure and there are no reports of how variability changes with predicted indifference. The purposes of this experiment were to reduce bias experimentally, and to contrast the difference limen (a measure of variability around indifference) with predictions from scalar expectancy theory (linear timing) and behavioral economic model (logarithmic timing). A control group of 6 rats performed the original time-left procedure with C=60 s and S=5, 10,…, 50, 55 s, whereas a no-bias group of 6 rats performed the same conditions in a modified time-left procedure in which only a single response per choice trial was allowed. Results showed that bias was reduced for the no-bias group, observed indifference grew linearly with predicted indifference for both groups, and difference limen and Weber ratios decreased as expected indifference increased for the control group, which is consistent with linear timing, whereas for the no-bias group they remained constant, consistent with logarithmic timing. Therefore, the time-left procedure generates results consistent with logarithmic perceived time once bias is experimentally reduced. Copyright © 2015 Elsevier B.V. All rights reserved.

Does an eight-week exercise program reduce the intensity and prevalence of low back pain in 12-13 year old children? Does it decrease the childhood physical risk factors for low back pain and promote a sense of well-being? Randomised trial with concealed allocation and assessor blinding. Seventy-two 12-13 year old children, who had complained of low back pain in the past three months. The experimental group completed eight exercise classes of 40-45 minutes duration over eight weeks conducted by a physiotherapist, whilst the control group received no intervention. The primary outcome was pain intensity measured on a 10-cm visual analogue scale. Secondary outcomes included 3-month prevalence of pain, childhood physical risk factors for low back pain, and sense of well-being. Measures were taken at baseline (Month 0), post-intervention (Month 3), and three months later (Month 6). Pain intensity over the past month had decreased by 2.2 cm (95% CI 1.0 to 3.5) more for the experimental group than the control group at Month 3 and was still 2.0 cm (95% CI 0.5 to 3.5) less than the control group at Month 6. The absolute risk reduction for 3-month prevalence in low back pain in the experimental group was 24% (95% CI 4 to 41) compared with the control group at Month 3, and 40% (95% CI 18 to 57) at Month 6. There were also statistically-significant between-group differences in neural mobility. Exercise is effective in reducing the intensity and prevalence of low back pain in children.

The aim of the research is to determine the effect of cold application on the pain owing to chest tube removal for patients with single pleural chest tube. Removal of chest tubes causes patients to feel pain and interventions used for reducing the pain owing to the removal of chest tubes are not sufficient. Controlled clinical trial with repeated measures. This study was conducted with 140 patients, of whom 70 patients were in the experimental group and 70 patients were in the control group, in a thoracic hospital in Turkey. Data were collected using a data collection form consisting of patients' demographic and health history and Visual Analogue Scale. Cold was applied to patients in the experimental group prior to chest tube removal. In the experimental group, skin temperature and pain intensity was measured for each patient at four time points. In the control group, pain intensity was evaluated for each patient at three time points. Data were evaluated using Chi-square and Repeated Measurements two-way anova tests. The Visual Analogue Scale score was measured immediately after the chest tube removal in the experimental group was 3·85, compared with 5·60 in the control group. There were significant differences on pain with cold application between the two groups prior and after the intervention. Age, gender, the number of days the chest tube was inserted and the chest tube insertion indication had no effect on the pain owing to chest tube removal. Cold application is effective in reducing the pain owing to chest tube removal. Cold application was recommended prior to chest tube removal to reduce the pain owing to removal of chest tube. © 2011 Blackwell Publishing Ltd.

2010-05-25

To describe and compare visual function measures of two groups of school age children (6-14 years of age) attending a specialist eyecare practice in Austria; one group referred to the practice from educational assessment centres diagnosed with reading and writing difficulties and the other, a clinical age-matched control group. Retrospective clinical data from one group of subjects with reading difficulties (n = 825) and a clinical control group of subjects (n = 328) were examined.Statistical analysis was performed to determine whether any differences existed between visual function measures from each group (refractive error, visual acuity, binocular status, accommodative function and reading speed and accuracy). Statistical analysis using one way ANOVA demonstrated no differences between the two groups in terms of refractive error and the size or direction of heterophoria at distance (p > 0.05). Using predominately one way ANOVA and chi-square analyses, those subjects in the referred group were statistically more likely to have poorer distance visual acuity, an exophoric deviation at near, a lower amplitude of accommodation, reduced accommodative facility, reduced vergence facility, a reduced near point of convergence, a lower AC/A ratio and a slower reading speed than those in the clinical control group (p < 0.05). This study highlights the high proportions of visual function anomalies in a group of children with reading difficulties in an Austrian population. It confirms the importance of a full assessment of binocular visual status in order to detect and remedy these deficits in order to prevent the visual problems continuing to impact upon educational development.

Introduction Aim of this study was to reduce blood loss caused by diagnostic blood sampling and to minimize the development of anemia in a high-risk group of mechanically ventilated medical intensive care patients. We therefore implemented a “blood-saving bundle” (BSB) combining a closed-loop arterial blood sampling system, smaller sampling tubes, reduced frequency of blood drawings, and reduced sample numbers. Methods The study included all patients from our medical ICU who were ventilated for more than 72 hours. Exclusion criteria were: acute or chronic anemia on admission, bleeding episode(s) during the ICU stay, or end-of-life therapy. The BSB was introduced in 2009 with training and educational support. Patients treated in 2008, before the introduction of the BSB, served as a control group (n = 41, 617 observation days), and were compared with patients treated in 2010 after the introduction of the BSB (BSB group, n = 50, 559 observation days). Primary endpoints were blood loss per day, and development of anemia. Secondary endpoints were numbers of blood transfusions, number of days on mechanical ventilation, and length of the ICU stay. Results Mean blood loss per ICU day was decreased from 43.3 ml (95% CI: 41.2 to 45.3 ml) in the controls to 15.0 ml (14.3 to 15.7 ml) in the BSB group (P < 0.001). The introduction of a closed-loop arterial blood sampling system was the major contributor to this effect. Mean hemoglobin concentrations showed no significant differences in both groups during the ICU stay. Hemoglobin values <9 g/dl, however, were recorded in 21.2% of observation days in the controls versus 15.4% in the BSB group (P = 0.01). Units of transfused red blood cells per 100 observation days decreased from 7 to 2.3 (P < 0.001). The mean number of ventilation days was 7.1 days (6.1 to 8.3 days) in the controls and 7.5 days (6.6 to 8.5 days) in the BSB group (P = NS). In total, patients in the BSB group stayed in ICU for a mean of 9.9 days (8.6 to 11.3 days), compared to a mean ICU stay of 13.0 days (10.9 to 15.4 days) in the control group (P = 0.014). Due to the longitudinal study design, however, we cannot exclude uncontrolled confounders affecting the transfusion frequency and mean ICU stay. Conclusion Our BSB could be easily implemented and was able to reduce diagnostic blood loss. PMID:26421920

We tested whether a brief cognitive behavioral (CB) group and bibliotherapy prevention reduce major depressive disorder (MDD) onset, depressive symptoms, and secondary outcomes relative to brochure controls in adolescents with self-reported depressive symptoms when school personnel recruit participants and deliver the intervention. Three hundred seventy-eight adolescents (M age = 15.5 years, SD = 1.2; 68% female, 72% White) with elevated self-assessed depressive symptoms were randomized to a 6-session CB group, minimal contact CB bibliotherapy, or educational brochure control. Participants were assessed at pretest, posttest, and 6-month follow-up. CB group participants showed a significantly lower risk for major depressive disorder onset (0.8%), compared to both CB bibliotherapy (6.3%) and brochure control (6.5%; hazard ratio = 8.1 and 8.3, respectively). Planned contrasts indicated that CB group resulted in lower depressive symptom severity than brochure control at posttest (p = .03, d = 0.29) but not 6-month follow-up; differences between CB group and bibliotherapy were nonsignificant at posttest and 6-month follow-up. Condition effects were nonsignificant for social adjustment and substance use. The finding that a brief CB group intervention delivered by real-world providers significantly reduced MDD onset relative to both brochure control and bibliotherapy is very encouraging, although effects on continuous outcome measures were small or nonsignificant and approximately half the magnitude of those found in efficacy research, potentially because the present sample reported lower initial depression.

HIV elite controllers suppress HIV viremia without antiretroviral therapy (ART), yet previous studies demonstrated that elite controllers maintain an activated T-cell phenotype. Chronic immune activation has detrimental consequences and thus ART has been advocated for all elite controllers. However, elite controllers are not a clinically homogenous group. Since CD4% is among the best predictors of AIDS-related events, in the current study, we assessed whether this marker can be used to stratify elite controllers needing ART. Sixteen elite controllers were divided into two groups based on CD4% (EC > 40% and EC ≤40%), and T-cell subsets were analyzed for markers of memory/differentiation (CD45RA, CCR7, CD28), activation (CD38/HLA-DR), immunosenescence (CD57), costimulation (CD73, CD28) and exhaustion (PD-1, CD160, Tim-3). Monocyte subsets (CD14, CD16) were also analyzed and sCD14 levels were quantified using ELISA. In the EC group, expression of activation, exhaustion, and immunosensescence markers on T cells were significantly reduced compared with the EC group and similar to the seronegative controls. The EC group expressed higher levels of costimulatory molecules CD28 and CD73 and had lower levels of monocyte activation (HLA-DR expression) with a reduced frequency of inflammatory monocyte (CD14 CD16) subset. Furthermore, the EC group maintained a stable CD4% during a median follow-up of 6 years. Elite controllers with preserved CD4T cells (EC) have normal T-cell and monocyte phenotypes and therefore may have limited benefit from ART. CD4% can be an important marker for evaluating future studies aimed at determining the need for ART in this group of individuals.

This randomized, double-blind controlled study evaluated the effectiveness of sodium bicarbonate-buffered lidocaine on reducing pain during imaging-guided breast biopsies. This prospective, HIPAA-compliant study randomly assigned 85 women undergoing ultrasound- or stereotactic-guided core-needle breast biopsies to receive intradermally and intraparenchymally either 1% lidocaine buffered with sodium bicarbonate (9:1 ratio) (bicarbonate study group) or 1% lidocaine alone (control group). Pain was evaluated using a 0-to-10 Likert pain scale during both intradermal and intraparenchymal anesthesia injections and during tissue sampling. Prebiopsy breast pain, anxiety, medical history, demographics, biopsy type, radiologist level of training, breast density, and lesion histology were recorded. Data were analyzed using analysis of variance and analysis of covariance. Unadjusted mean pain scores were 1.47 and 2.07 (study and control groups, respectively; P = .15) during intradermal injections, and 1.84 and 2.98 (study and control groups, respectively; P = .03) during intraparenchymal injections. Tissue sampling mean pain scores were .81 and 1.71 (study and control groups, respectively; P = .07). Moderator analyses found (1) among patients with preprocedural pain, those in the bicarbonate group experienced less intradermal injection pain (0.85 ± 1.23) than patients in the control group (2.50 ± 2.09); (2) among patients with fatty or scattered fibroglandular tissue, those in the bicarbonate group (1.35 ± 1.95) experienced less intraparenchymal injection pain than the control group (3.52 ± 3.13); and (3) during ultrasound-guided biopsies, patients in the bicarbonate group experienced less tissue-sampling pain (0.23 ± 0.63) than the control group (1.79 ± 3.05). Overall, buffering lidocaine with sodium bicarbonate significantly reduced pain during intraparenchymal injections, and additional pain reduction was found in certain patient subgroups during intradermal injections, intraparenchymal injections, and tissue sampling.

Reducing perioperative blood loss and the need for transfusions in patients undergoing spinal surgery is especially important for those with neuromuscular disorders. These patients require extensive spino-pelvic exposure and are often medically fragile. We have used Amicar to decrease blood loss since 2001. As an effort to further reduce blood loss and transfusions, we use a bipolar sealer device (Aquamantys) as an adjunct to electrocautery. We present the results of our first 64 neuromuscular patients to show the efficacy of the device. Using a prospectively maintained database we reviewed the operative time, estimated perioperative blood loss, cell saver use, and intraoperative and postoperative transfusion rate in patients who underwent posterior spinal fusion for neuromuscular scoliosis. Sixty-four patients were identified who fit these criteria since the use of the bipolar sealer device was instituted.We compared these patients with a control group of the preceding 65 patients in whom this device was not used for hemostasis. All patients, including those in the study group, received Amicar (infusion of 100 mg/kg over 15 to 20 min, then 10 mg/kg/h throughout the remainder of the procedure). The surgical technique did not differ between the 2 groups. Baseline characteristics between the 2 groups were similar except for the number of patients having an all-screw construct which was larger in the investigational group (25% vs. 8%, P=0.03). There were no significant differences in operative time or duration of hospital stay. Intraoperative blood loss was lower in the study group (741 mL) as compared with the control group (1052 mL, P=0.003). Total perioperative blood loss, however, showed no significant difference. Thirty-five (55%) patients in the study group and 50 (77%) patients in the control group required additional intraoperative or postoperative transfusions (P=0.01). The number of packed red cell units transfused per patient was 0.81 in the study group and 1.57 in the control group (P=0.001). Although the intraoperative cell saver transfusion was same, the total blood volume transfused, which includes cell saver and any other transfusions, was significantly lower in the study group, 425 mL versus 671 mL (P=0.002). Use of a bipolar sealer device in posterior spinal fusion for neuromuscular scoliosis significantly reduced intraoperative blood loss and transfusion rate when compared with a control group in this retrospective review. Level III-retrospective comparative study.

Effects of dance on anxiety.

Lesté, A; Rust, J

1984-06-01

The study investigated the effects of modern dance on anxiety. State anxiety was assessed before and after a 3-mo. education programme, using the Spielberger State-Trait Anxiety Inventory. The target group followed a class in modern dance. Control groups were (1) a physical education group to control for the effects of exercise, (2) a music group to control for aesthetic sensitivity training, and (3) a mathematics group. Several concomitant variables were measured: age, sex, attitude towards dance, and previous experience in sport, dance, and relaxation. Dance training significantly reduced anxiety, but no control activities did so. Examination of the concomitant variables showed that the result could not be accounted for by any obvious artifacts.

This study evaluated the effectiveness of a parent based intervention (PBI) in reducing drinking among first year college students (N=443). Students were assigned to one of three conditions: PBI, PBI plus booster brochures (PBI-B), and an assessment only control group (CNT). At a 4-month post-intervention follow-up, results indicated students in the PBI-B group reported significantly less drinking to intoxication and peak drinking relative to the PBI group and CNT group. No significant differences were found between the PBI group and CNT group. Results provide further support for PBIs to reduce college student drinking and suggest that a booster brochure increases the effectiveness of PBIs. Copyright © 2013 Elsevier Inc.

This study was done out to evaluate the effects of Sida rhombifolia methanol extract (SRM) on diabetes in moderately diabetic (MD) and severely diabetic (SD) Sprague-Dawley rats. SRM was prepared by soaking the powdered plant material in 70% methanol and rota evaporating the methanol from the extract. Effective hypoglycemic doses were established by performing oral glucose tolerance tests (OGTTs) in normal rats. Hourly effects of SRM on glucose were observed in the MD and the SD rats. Rats were grouped, five rats to a group, into normal control 1 (NC1), MD control 1 (MDC1), MD experimental 1 (MDE1), SD control 1 (SDC1), and SD experimental 1 (SDE1) groups. All rats in the control groups were administered 1 mL of distilled water (DW). The rats in the MDE1 and the SDE1 groups were administered SRM orally at 200 and 300 mg/kg body weight (BW), respectively, dissolved in 1 mL of DW. Blood was collected initially and at intervals of 1 hour for 6 hours to measure blood glucose. A similar experimental design was followed for the 30-day long-term trial. Finally, rats were sacrificed, and blood was collected to measure blood glucose, lipid profiles, thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH). OGTTs indicated that two doses (200 and 300 mg/kg BW) were effective hypoglycemic doses in normal rats. Both doses reduced glucose levels after 1 hour in the MDE1 and the SDE1 groups. A long-term trial of SRM in the MD group showed a reduced glucose level, a normal lipid profile, and normal GSH and TBARS levels. In SD rats, SRM had no statistically significant effects on these parameters. Normal weight was achieved in the MD rats, but the SD rats showed reduced BW. The study demonstrates that SRM has potential to alleviate the conditions of moderate diabetic, but not severe diabetes.

The objective of this study was to examine the efficacy of progressive muscle relaxation training on anxiety in patients with acute schizophrenia. Many empirical studies have found progressive muscle relaxation training beneficial in reducing the psychological effects of anxiety. Progressive muscle relaxation training is also effective in reducing the distress symptoms associated with the symptomatology of schizophrenia. An experimental randomised controlled trial using repeated measures. The study was designed to examine the effects of progressive muscle relaxation training on patients diagnosed with schizophrenia. Study participants were acute psychiatric inpatients in Taiwan. Eighteen patients were block randomised and then assigned to an experimental or control group. The experimental group received progressive muscle relaxation training and the control group received a placebo intervention. Results from the Beck anxiety inventory were compared between groups as a pretest before intervention, on day 11 of intervention and one week post-test after the intervention was completed. Changes in finger temperature were measured throughout the experiment. The degree of anxiety improvement was significantly higher in the progressive muscle relaxation training group than in the control group after progressive muscle relaxation training intervention (p < 0.0001) and at follow-up (p = 0.0446; the mean BAI score fell from 16.4 pretest to -5.8 post-test. After adjusting for the change in patient finger temperature, the mean change in temperature was significantly different between the two patient groups. The average body temperature increased significantly after applying the progressive muscle relaxation training to patients with schizophrenia. This study demonstrated that progressive muscle relaxation training can effectively alleviate anxiety in patients with schizophrenia. Progressive muscle relaxation training is potentially an effective nursing intervention in the reduction of anxiety in patients diagnosed with schizophrenia, depending on the quality of their mental status at the time of intervention. Progressive muscle relaxation training is a useful intervention as it is proven to reduce anxiety levels across a spectrum of psychiatric disorders.

To evaluate the contribution of respiratory muscle weakness (part 1) and respiratory muscle training (part 2) to pulmonary function, cough efficacy, and functional status in patients with advanced multiple sclerosis (MS). Survey (part 1) and randomized controlled trial (part 2). Rehabilitation center for MS. Twenty-eight bedridden or wheelchair-bound MS patients (part 1); 18 patients were randomly assigned to a training group (n = 9) or a control group (n = 9) (part 2). The training group (part 2) performed three series of 15 contractions against an expiratory resistance (60% maximum expiratory pressure [PEmax]) two times a day, whereas the control group performed breathing exercises to enhance maximal inspirations. Forced vital capacity (FVC), inspiratory, and expiratory muscle strength (PImax and PEmax), neck flexion force (NFF), cough efficacy by means of the Pulmonary Index (PI), and functional status by means of the Extended Disability Status Scale (EDSS). Part 1 revealed a significantly reduced FVC (43% +/- 26% predicted), PEmax (18% +/- 8% predicted), and PImax (27% +/- 11% predicted), whereas NFF was only mildly reduced (93% +/- 26% predicted). The PI (median score, 10) and EDSS (median score, 8.5) were severely reduced. PEmax was significantly correlated to FVC, EDSS, and PI (r = .77, -.79, and -.47, respectively). In stepwise multiple regression analysis. PEmax was the only factor contributing to the explained variance in FVC (R2 = .60), whereas body weight (R2 = .41) was the only factor for the PI. In part 2, changes in PImax and PEmax tended to be higher in the training group (p = .06 and p = .07, respectively). The PI was significantly improved after 3 months of training compared with the control group (p < .05). After 6 months, the PI remained significantly better in the training group. Expiratory muscle strength was significantly reduced and related to FVC, cough efficacy, and functional status. Expiratory muscle training tended to enhance inspiratory and expiratory muscle strength. In addition, subjectively and objectively rated cough efficacy improved significantly and lasted for 3 months after training cessation.

Guided imagery and music can reportedly reduce pain and anxiety during surgery, but no comparative study has been performed for cutaneous surgery to our knowledge. We sought to determine whether short-contact recorded guided imagery or relaxing music could reduce patient pain and anxiety, and surgeon anxiety, during cutaneous surgical procedures. Subjects were adults undergoing excisional surgery for basal and squamous cell carcinoma. Randomization was to guided imagery (n = 50), relaxing music (n = 54), or control group (n = 51). Primary outcomes were pain and anxiety measured using visual analog scale and 6-item short-form of the State-Trait Anxiety Inventory, respectively. Secondary outcomes were anxiety of surgeons measured by the 6-item short-form of the State-Trait Anxiety Inventory and physical stress of patients conveyed by vital signs, respectively. There were no significant differences in subjects' pain, anxiety, blood pressure, and pulse rate across groups. In the recorded guided imagery and the relaxing music group, surgeon anxiety was significantly lower than in the control group. Patients could not be blinded. Short-contact recorded guided imagery and relaxing music appear not to reduce patient pain and anxiety during excisional procedures under local anesthetic. However, surgeon anxiety may be reduced when patients are listening to such recordings. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

Diabetes is a chronic, potentially debilitating, and often fatal disease. Dietary strategies to reduce postprandial glycemia are important in the prevention and treatment of diabetes. Nuts are rich in mono- and polyunsaturated fatty acids, which may reduce hyperglycemia and improve metabolism. To evaluate the effectiveness of pistachio nut supplementation on glycemic and inflammatory measures in patients with type 2 diabetes. In this double-blind, randomized, placebo-controlled, crossover trial, 48 diabetic patients were equally assigned to groups A and B. Patients in group A received a snack of 25 g pistachio nuts twice a day for 12 weeks and group B received a control meal without nuts. After 12 weeks of intervention, the patients had an 8-week washout. Then the groups were displaced, and group B received the same amount of pistachios for 12 weeks. With respect to the total change in variables over both phases, there was a marked decrease in HbA1c (-0.4%) and fasting blood glucose (FBG) concentrations (-16 mg/dl) in the pistachio group compared with the control group (p ≤ 0.001 for both). There was no overall significant change in BMI, blood pressure, HOMA-IR, and C-reactive protein (CRP) concentrations. Analysis of the two phases separately showed a decrease in FBG by 14 mg/dl and in HbA1c by 0.45% in the treatment group (A) after 12 weeks, while no significant differences were seen in group B (control group). In the second phase, FBG decreased from 151.36 ± 39.22 to 137.28 ± 28.65 mg/dl (-14 mg/dl) and HbA1c decreased from 7.42 ± 0.97 to 7.15 ± 0.68 mg/dl (-0.28%, p = 0.013 and p = 0.033, respectively) in the pistachio group (B). Pistachio consumption reduced systolic blood pressure (p = 0.007), BMI (p = 0.011), and CRP (p = 0.002) in patients from the treatment groups, but not insulin resistance. Dietary consumption of pistachio nuts as a snack has beneficial effects on glycemic control, blood pressure, obesity, and inflammation markers in diabetic patients.

Public stigma alters attitudes towards people with mental illness, and is a particular concern for young people since most mental health problems occur in adolescence and young adulthood. However, little is known about the long-term effects of repeated filmed social contact (FSC) on reducing mental health-related stigma among young adults in the general population, compared with self-instructional Internet search (INS) and control interventions. This study is a parallel-group randomised controlled trial over 12 months conducted in Tokyo, Japan. A total of 259 university students (male n = 150, mean age = 20.0 years, s.d. = 1.2) were recruited from 20 colleges and universities between November 2013 and July 2014, without being provided information about the mental health-related survey or trial. Participants were assigned to one of three groups before completion of the baseline survey (FSC/INS/control = 89/83/87). The FSC group received a computer-based 30-min social contact film with general mental health education and five follow-up web-based FSCs at 2-month intervals. The INS group undertook a 30-min search for mental health-related information with five follow-up web-based reminders for self-instructional searches at 2-month intervals. The control group played PC games and had no follow-up intervention. The main outcome measures were the future (intended behaviour) domain of the Reported and Intended Behaviour Scale at 12 months after the intervention. Analysis was conducted in September 2015. At the 12-month follow-up, 218 participants completed the survey (84.1%, 75:70:73). The FSC group showed the greatest change at the 12-month follow-up (FSC: mean change 2.11 [95% CI 1.49, 2.73], INS: 1.04 [0.29, 1.80], control: 0.71 [0.09, 1.33]; FSC v. INS p = 0.037, FSC v. controls p = 0.004). No adverse events were reported during the follow-up period. FSC was more successful in reducing stigma at 12 months after intervention than INS or control interventions. FSC could be used to reduce stigma in educational lectures and anti-stigma campaigns targeted at young people. This study is registered at UMIN-CTR (No. UMIN000012239).

Cigarette craving usually occurs in conjunction with unpleasant feelings, including stress, as part of a withdrawal syndrome. Progressive muscle relaxation (PMR), a behavioral technique used to reduce stress by concentrating on achieving muscle relaxation, may reduce levels of cigarette craving and other substance-related negative feelings and withdrawal symptoms. Demographic and cigarette use data were collected from 32 experienced smokers at the King Chulalongkorn Memorial Hospital, Bangkok, Thailand using the Semi-Structured Assessment for Drug Dependence and Alcoholism. Participants were asked to refrain from smoking for at least 3 hours before the visit (acute abstinence) and were randomly allocated to a 1-session PMR group (n =16) or a control activity group (e.g., reading newspaper, n =16). The intervention group was instructed to practice PMR individually in a quiet, private, air-conditioned room for about 20minutes. Craving, other substance-related feelings, and autonomic nervous responses (e.g., blood pressure and pulse rate) were assessed immediately before and after the 1-session intervention. There were no differences in demographics, cigarette use/dependence, and baseline craving characteristics between the PMR and control groups. However, the control group had higher levels of high and paranoia feeling, and pulse rate than the PMR group at baseline. After practicing PMR, but not after a control activity, smokers undergoing acute abstinence had significantly lower levels of cigarette craving, withdrawal symptoms, and systolic blood pressure than at baseline. After controlling for baseline differences, abstaining smokers using PMR had lower levels of cigarette craving, withdrawal symptoms, and systolic blood pressure than smokers who undertook a control activity. PMR significantly reduces cigarette craving, withdrawal symptoms, and blood pressure in smokers undergoing acute abstinence. PMR may be used as an adjunct to cigarette dependency treatments.

1976-04-01

The authors had previously observed that dietary NaF administered to rats during the formative and eruptive stages of tooth development does not significantly reduce the enamel solubility in acid buffer solution. They hypothesized that NaF reduces the cariogenicity of the bacterial flora. In order to test this hypothesis, rats from the same litter were divided into three groups all of which received a cariogenic diet. Group one received no fluoride. Groups two and three were supplemented with 50 ppm NaF, from day 1 to day 21. In the first study, one of the 21-day-old NaF-supplemented groups was inoculated by smearsmore » of fecal material from the control animals that did not receive NaF supplement. The second NaF group was not inoculated and served as control. In a second study, cariogenic Strep. mutans 6715 was used as the inoculum in place of the fecal smear. In both studies, the inoculation of a NaF group increased the caries to about 70% of the control group, while the mean scores on the non-inoculated NaF group were about 50% of the control group. These results indicate that alteration of the transmissible flora may be an important factor in the cariostatic action of dietary fluoride in experimental animals. This observation supports the suggestion that fluoride may alter the cariogenic flora.« less

Background and purpose Prevention of osteonecrosis after corticosteroid administration would be important. We examined the potential of vitamin E (α-tocopherol) to reduce the incidence of corticosteroid-induced osteonecrosis in an animal model. Methods Japanese white rabbits were divided into 2 groups; the control group was fed a normal diet and the experimental group was fed α-tocopherol-supplemented diet in which α-tocopherol (600 mg/kg diet) was added to the normal diet. To induce osteonecrosis, high-dose methylprednisolone acetate (MPSL) (20 mg/kg body weight) was injected once into the right gluteus medius muscle of all rabbits. 4 weeks after the injection of MPSL, the presence or absence of osteonecrosis of bilateral femurs was examined histopathologically. The tocopherol/cholesterol ratios were calculated. The plasma levels of thiobarbituric acid-reactive substances (TBARS) were measured. Results Alpha-tocopherol-supplemented diet reduced the incidence of osteonecrosis, which developed in 14 of 20 rabbits in the control group and 5 of 21 rabbits in the experimental group (p = 0.004). The tocopherol/cholesterol ratio was higher in the experimental group than in the control group after the α-tocopherol administration. The plasma TBARS level was lower in the experimental group than in the control group at 4 weeks after the MPSL administration. Interpretation Our findings may offer a new approach for the prevention of corticosteroid-induced osteonecrosis. PMID:20146637

The research aimed to investigate the effectiveness of cupping therapy (CT) in changes on skin surface temperature (SST) for relieving chronic neck and shoulder pain (NSP) among community residents. A single-blind experimental design constituted of sixty subjects with self-perceived NSP. The subjects were randomly allocated to two groups. The cupping group received CT at SI 15, GB 21, and LI 15 acupuncture points, and the control group received no intervention. Pain was assessed using the SST, visual analog scale (VAS), and blood pressure (BP). The main results were SST of GB 21 acupuncture point raised from 30.6°C to 32.7°C and from 30.7°C to 30.6°C in the control group. Neck pain intensity (NPI) severity scores were reduced from 9.7 to 3.6 in the cupping group and from 9.7 to 9.5 in the control group. The SST and NPI differences between the groups were statistically significant (P < 0.001). One treatment of CT is shown to increase SST. In conjunction with the physiological effect the subjective experience of NSP is reduced in intensity. Further studies are required to improve the understanding and potential long-term effects of CT.

To investigate the signal transduction mechanism of matrix metalloproteinase-9 (MMP-9) mediated- vascular endothelial growth factor (VEGF) expression and retinal neovascularization (RNV) in oxygen-induced retinopathy (OIR) model. C57BL/6J mice were divided into four groups: control group, OIR group, OIR control group (phosphate-buffered saline by intravitreal injection) and treated group [tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) by intravitreal injection]. OIR model was established in C57BL/6J mice exposed to 75%±2% oxygen for 5d. mRNA level and protein expression of MMP-9, TIMP-1 and VEGF were measured by real-time polymerase chain reaction and Western blotting, and located by immunohistochemistry. Levels of MMP-9 and VEGF in retina were significantly increased in animals with OIR and OIR control group. Levels of TIMP-1 in retina was significantly reduced in animals with OIR and OIR control group. Furthermore, a significant correlation was found between MMP-9 and VEGF. Intravitreal injection of TIMP-1 significantly reduced MMP-9 and VEGF expression of the OIR mouse model (all P<0.05). These results demonstrate that MMP-9-mediated up-regulation of VEGF promotes RNV in retinopathy of prematurity (ROP). TIMP-1 may be a potential target for the prevention and treatment of ROP.

This study aimed to evaluate the effects of treatment with different powers of Nd: YAG laser irradiation on root surfaces and Streptococcus mutans (S. mutans) adhesion. Extracted teeth because of severe periodontal disease were divided into the following four groups: control group, laser group 1, laser group 2, and laser group 3. After scaling and root planning, laser group 1, laser group 2, and laser group 3 were separately treated with Nd: YAG laser irradiation (4/6/8 W, 60 s); however, the control group did not receive the treatment. Scanning electron microscopy (SEM) was used to determine the morphology. S. mutans were cultured with root slices from each group. Colony forming unit per mL (CFU·mL⁻¹) was used to count and compare the amounts of bacteria adhesion among groups. SEM was used to observe the difference of bacteria adhesion to root surfaces between control group (scaling) and laser group 2 (6 W, 60 s), thereby indicating the different bacteria adhesions because of different treatments. Morphology alterations indicated that root surfaces in control group contain obvious smear layer, debris, and biofilm; whereas the root surfaces in laser group contain more cracks with less smear layer and debris. The bacteria counting indicated that S. mutans adhesion to laser group was weaker than that of control group (P<0.05). No statistical significance among the laser groups (P>0.05) was observed. Morphology alterations also verified that S. mutans adhesion to laser group 2 (6 W, 60 s) was weaker than that of control group (scaling). This study demonstrated that Nd: YAG laser irradiation treatment after scaling can reduce smear layer, debris, and biofilm on the root surfaces as compared with conventional scaling. The laser treatment reduces the adhesion of S. mutans as well. However, Nd: YAG laser irradiation can cause cracks on the root surfaces. In this experiment, the optimum laser power of 6 W can thoroughly remove the smear layer and debris, as well as relatively improve the control of thermal damagee.

Introduction: Nausea is the worst and most prevalent chemotherapy-induced complication experienced by 70–80% of patients despite mediation therapy. Reduction of nausea is one of the most important roles of oncologist nurses. Today, complementary therapies in addition to classic medicine, because of their lower costs, receive much attention. Nonetheless, their safety and effectiveness are not yet proven. The purpose of this research was to investigate the effect of therapeutic touch plan as a complementary therapy on acute nausea in women with breast cancer in 2012–2013 in Isfahan, Iran. Materials and Methods: A quasi-experimental, single-blind, randomized control trial with three groups (control, placebo and intervention) was performed at the Isfahan Seyedolshohada (AS) Teaching Hospital, Isfahan, in 2012–2013. The intervention was therapeutic touch plan on women with breast cancer, with the three groups receiving the same medicine regimen. Information was recorded by a checklist after infusion of chemotherapy drugs. Data analysis was performed by SPSS, ANOVA and Kruskal–Wallis tests. Results: The ANOVA test showed that the therapeutic touch plan was significantly effective in reducing the duration of nausea compared with the control and placebo groups (P < 0.001). The Kruskal–Wallis test showed that the frequency of occurrence of nausea was also reduced in the intervention and placebo groups compared with the control group (P < 0.001). The therapeutic touch plan was significantly effective in delaying the onset of nausea compared with the control and placebo groups (P < 0.001). Conclusion: This research showed that the therapeutic touch plan is effective in reducing acute chemotherapy-induced nausea; thus, education and implementation of the therapeutic touch plan is proposed for clinical nurses.

Cervical proprioception plays a key role in postural control, but its specific contribution is controversial. Postural impairment was shown in whiplash injuries without demonstrating the sole involvement of the cervical spine. The consequences of degenerative cervical spine diseases are underreported in posture-related scientific literature in spite of their high prevalence. No report has focused on the two different mechanisms underlying cervicobrachial pain: herniated discs and spondylosis. This study aimed to evaluate postural control of two groups of patients with degenerative cervical spine diseases with or without optokinetic stimulation before and after surgical treatment. Seventeen patients with radiculopathy were recruited and divided into two groups according to the spondylotic or discal origin of the nerve compression. All patients and a control population of 31 healthy individuals underwent a static posturographic test with 12 recordings; the first four recordings with the head in 0° position: eyes closed, eyes open without optokinetic stimulation, with clockwise and counter clockwise optokinetic stimulations. These four sensorial situations were repeated with the head rotated 30° to the left and to the right. Patients repeated these 12 recordings 6weeks postoperatively. None of the patients reported vertigo or balance disorders before or after surgery. Prior to surgery, in the eyes closed condition, the herniated disc group was more stable than the spondylosis group. After surgery, the contribution of visual input to postural control in a dynamic visual environment was reduced in both cervical spine diseases whereas in a stable visual environment visual contribution was reduced only in the spondylosis group. The relative importance of visual and proprioceptive inputs to postural control varies according to the type of pathology and surgery tends to reduce visual contribution mostly in the spondylosis group.

Findings from a large, randomized controlled trial of couple education are presented in this brief report. Married Army couples were assigned to either PREP for Strong Bonds (n = 248) delivered by Army chaplains or to a no-treatment control group (n = 228). One year after the intervention, couples who received PREP for Strong Bonds had 1/3 the rate of divorce of the control group. Specifically, 6.20% of the control group divorced while 2.03% of the intervention group divorced. These findings suggest that couple education can reduce the risk of divorce, at least in the short run with military couples. PMID:20634994

Typing is associated with musculoskeletal disorders (MSDs) caused by multiple risk factors. This control study aimed to evaluate the efficacy of a workplace intervention for reducing MSDs among computer workers. Sixty-six subjects with and without MSD were assigned consecutively to one of three groups: ergonomics intervention (work site and body posture adjustments, muscle activity training and exercises) accompanied with biofeedback training, the same ergonomics intervention without biofeedback and a control group. Evaluation of MSDs, body posture, psychosocial status, upper extremity (UE) kinematics and muscle surface electromyography were carried out before and after the intervention in the workplace and the motion lab. Our main hypothesis that significant differences in the reduction of MSDs will exist between subjects in the study groups and controls was confirmed (χ(2) = 13.3; p = 0.001). Significant changes were found in UE kinematics and posture as well. Both ergonomics interventions effectively reduced MSD and improved body posture. This study aimed to test the efficacy of an individual workplace intervention programme among computer workers by evaluating musculoskeletal disorders (MSDs), body posture, upper extremity kinematics, muscle activity and psychosocial factors were tested. The proposed ergonomics interventions effectively reduced MSDs and improved body posture.

Perioperative blood loss after total knee arthroplasty (TKA) affects postoperative recovery. Tranexamic acid is safe and efficient in reducing blood loss without increasing thromboembolic events. Epsilon-aminocaproic acid (ε-ACA) is less expensive than and as safe as tranexamic acid. Its efficiency when locally applied in TKA is unknown. The authors retrospectively followed 240 consecutive patients treated by 1 surgeon with TKA from January 2012 to August 2016. From January 2013 to May 2015, the authors topically applied 5 g of ε-ACA to the open wound after tourniquet release and before closure (ε-ACA-after-tourniquet-release group). From August 2015 to August 2016, the authors topically applied 5 g of ε-ACA intraoperatively to the open wound 3 minutes before tourniquet release (ε-ACA-before-tourniquet-release group). The last 80 patients not receiving ε-ACA (control group), the 80 patients in the ε-ACA-after-tourniquet-release group, and the 80 patients in the ε-ACA-before-tourniquet-release group were compared regarding blood loss, treatment costs, and thromboembolic complications. The mean±SD calculated blood loss was 1478.8±367.1 mL for the control group, 1424.0±249.3 mL for the ε-ACA-after-tourniquet-release group, and 1052.3±419.1 mL for the ε-ACA-before-tourniquet-release group (P<.05). Using ε-ACA before tourniquet release reduced the length of hospital stay by 0.7 days (P<.05) compared with not using ε-ACA, leading to cost savings of $1547.37 per patient. One patient in the ε-ACA-before-tourniquet-release group and 1 patient in the control group developed a venous thromboembolism in the postoperative period. Epsilon-aminocaproic acid significantly reduces blood loss after TKA when topically applied before tourniquet release. Its application reduced costs by decreasing the length of hospital stay and did not increase thromboembolic events. [Orthopedics. 2017; 40(6):e1044-e1049.]. Copyright 2017, SLACK Incorporated.

The purpose of this study was to investigate whether lavender oil aromatherapy can reduce the bispectral index (BIS) values and stress and decrease the pain of needle insertion in 30 volunteers. Thirty (30) healthy volunteers were randomly allocated to 2 groups: the experimental group received oxygen with a face mask coated with lavender oil for 5 minutes, and the control group received oxygen through a face mask with no lavender oil for 5 minutes. The stress level (0=no stress, 10=maximum stress), BIS value, and pain intensity of needle insertion (0=no pain, 10=worst pain imaginable) were measured. There were no significant differences in age, sex, height, and weight between the two groups. Stress level, BIS value, and pain intensity of needle insertion before aromatherapy were similar between the two groups. However, the stress values (p<0.001) and BIS value (p<0.001) after aromatherapy were significantly reduced compared with the control. In addition, the pain intensity of needle insertion was significantly decreased after aromatherapy compared with the control (p<0.001). Lavender aromatherapy in volunteers provided a significant decrease in the stress levels and in the BIS values. In addition, it significantly reduced the pain intensity of needle insertion.

To study in vitro sperm damage caused by trichloroethylene in male rats. Sperms of Sprague-Dawley (SD) rats were collected 4 hours after being contaminated by trichloroethylene of 0, 2, 4, 6, 8, and 10 mmol/L in vitro. Giemsa staining was performed to observe the morphological changes of sperms, and flow cytometer was used to detect the changes in mitochondrial membrane potential. The sperm motilities in 6, 8, and 10 mmol/L trichloroethylene groups decreased significantly compared with that in control group (P <0.01); the sperm aberration rates in 8 and 10 mmol/L trichloroethylene groups were significantly higher than that in control group (P<0.01). With the increase in exposure dose, the proportion of sperms with reduced mitochondrial membrane potential increased, and there were significant differences in sperm apoptosis rate between the 4, 6, 8, and 10 mmol/L trichloroethylene groups and control group (P<0.01). In vitro exposure to trichloroethylene can reduce sperm motility and increase the aberration rate and apoptosis rate of sperms in male SD rats.

Phlebitis is the commonest complication of intravenous infusion. It has been suggested that it is initiated by venoconstriction at the infusion site, hence treatment with a vasodilator may reduce its incidence. A prospective controlled study was carried out on the effect of transdermal glyceryl trinitrate (GTN) and topical anti-inflammatory gel (non-steroidal anti-inflammatory drug; NSAID) on the survival of peripheral intravenous infusion in 386 patients. A total of 34.9% (43 out of 123) of the infusions failed in the control group compared with 14.1% (18 out of 127) in the NSAID group (P < 0.05) and 30.8% (43 out of 136) in the GTN group (P < 0.05). In the control group 31 positive cultures were obtained. Twenty-one positive cultures were obtained in the GTN group and four cases of bacterial proliferation were observed in the NSAID group. Infusion phlebitis is a common problem in hospitalized patients and its incidence can be effectively reduced by NSAI gel and GTN but NSAI gel is more effective than GTN.

Type 2 diabetes has been associated with dysbiosis and one of the possible routes to restore a healthy gut microbiota is by the regular ingestion of probiotics. We aimed to investigate the effects of probiotics on glycemic control, lipid profile, inflammation, oxidative stress and short chain fatty acids in T2D. In a double-blind, randomized, placebo-controlled trial, 50 volunteers consumed daily 120 g/d of fermented milk for 6 wk. Participants were assigned into two groups: probiotic group, consuming fermented milk containing Lactobacillus acidophilus La-5 and Bifidobacterium animalis subsp lactis BB-12 (10 9  colony-forming units/d, each) and control group, consuming conventional fermented milk. Anthropometric measurements, body composition, fasting blood and faecal samples were taken at baseline and after 6 wk. 45 subjects out of 50 (90%) completed follow-up. After 6 wk, there was a significant decrease in fructosamine levels (-9.91 mmol/L; p = 0.04) and hemoglobin A 1 c tended to be lower (-0.67%; p=0.06) in probiotic group. TNF-α and resistin were significantly reduced in probiotic and control groups (-1.5 and -1.3 pg/mL, -.1 and -2.8 ng/mL, respectively), while IL-10 was significantly reduced (- 0.65 pg/mL; p <0.001) only in the control group. Fecal acetic acid was increased in both groups (0.58 and 0.59% in probiotic and control groups, respectively; p <0.01). There was a significant difference between groups concerning mean changes of HbA 1c (+0.31 for control group vs -0.65 for probiotic group; p=0.02), total cholesterol (+0.55 for control group vs -0.15 for probiotic group; p=0.04) and LDL-cholesterol (+0.36 for control group vs -0.20 for probiotic group p=0.03). Probiotic consumption improved the glycemic control in T2D subjects, however, the intake of fermented milk seems to be involved with others metabolic changes, such as decrease in inflammatory cytokines (TNF-α and resistin) and increase in the acetic acid.

To examine the effect of levothyroxine (L-T4), vitamin E or both on oxidative stress status and hippocampal apoptosis in a propylthiouracil (PTU)-induced hypothyroid rat model. Sprague-Dawley rats were randomly divided into five groups: Control, PTU+PTU+L-T4+PTU+Vit E, PTU+Vit E+L-T4. In each group we assessed levels of serum triiodothyronine (T3), tetraiodothyronine (T4), thyroid stimulating hormone (TSH), hippocampus cellular apoptosis index (AI), hippocampus nicotinamide adenine denucleotide hydrogen (NADPH)oxidase and superoxide dismutase (SOD). 1) Compared with the control group, NADPH oxidase levels were significantly increased, and SOD levels were significantly reduced in the PTU groups (p<0.05). 2) Compared to the PTU group, SOD levels were significantly increased in the PTU+Vit E and PTU+L-T4+Vit E group (p<0.05). NADPH oxidase levels were significantly decreased in the PTU+L-T4, PTU+Vit E and PTU+ L-T4+Vit E group (p<0.05). 3) Compared with the control group, hippocampus AI increased significantly in the PTU group (p<0.05). Compared with the PTU group, hippocampus AI was significantly reduced in the PTU+L-T4 group and PTU+L-T4+Vit E group (p<0.05). 4) Hippocampus AI was positively correlated with NADPH oxidase expression levels in hippocampus tissue (r=0.644, p<0.01). Levothyroxine replacement therapy combined with vitamin E reduces hippocampus AI by improving oxidative stress. This study suggested that the mechanisms of hippocampus tissue injury in a hypothyroid rat model is related to hippocampus apoptosis from increased oxidative stress.

Effectiveness of a dental gel to reduce plaque in beagle dogs.

Hennet, Philippe

2002-03-01

Tooth brushing is considered a superior technique for reducing plaque accumulation. Chemical agents may be used to reduce plaque accumulation on tooth surfaces since many owners may not be willing or able to brush their dog's teeth. Following a professional teeth cleaning procedure, a dental gel containing chlorhexidine was applied in 11 dogs BID for 7-days, while 11 other dogs received a control dental gel applied in the same manner. Dogs in the treatment group had significantly less plaque accumulation during the trial period compared with dogs in the control group. The dental gel applied in the study reported here decreases plaque accumulation in the short-term and may be beneficial in reducing the severity of gingivitis and associated periodontal disease if provided on a long-term basis.

Most people with dementia develop neuropsychiatric symptoms (NPSs), which are distressing for their carers. Untreated pain may increase the prevalence and severity of NPSs and thereby staff burden. We investigated the association between NPSs and the impact of individual pain treatment on distress in nursing home staff. Nursing home (NH) units were cluster-randomized to an intervention group (33 NH units; n = 175) or control group (27 NH units; n = 177). Patients in the intervention group received individual pain treatment for eight weeks, followed by a four-week washout period; control groups received care as usual. Staff informants (n = 138) used the Neuropsychiatric Inventory-NH version (including caregiver distress) as primary outcome to assess their own distress. Other outcomes were pain (Mobilization-Observation-Behavior-Intensity-Dementia-2 Pain Scale) and cognitive functioning (Mini-Mental State Examination). Using hierarchical regression analysis, all NPS items at baseline were associated with staff distress (P < 0.01) apart from euphoria; agitation had the largest contribution (β = 0.24). Using mixed models, we found significantly lower staff distress in the intervention group compared to the control group. Moreover, we also found significantly reduced distress in the control group, and there were still effects in both groups throughout the washout period. Individual pain treatment reduced staff distress in the intervention group compared to control group especially in regard to agitation-related symptoms and apathy. Furthermore, our results indicated a multifactorial model of staff distress, in which enhanced knowledge and understanding of NPSs and pain in people with advanced dementia may play an important role.

Broilers in four groups were fed a basal diet supplemented with 60 mg/kg zinc oxide (60-ZnO; control), or 20, 60, or 100 mg/kg ZnO nanoparticles (20-, 60-, and 100-nano-ZnO, respectively). Compared with the controls, after 14 days, birds in the 20- and 60-nano-ZnO groups had significantly greater weight gains and better feed conversion ratios. However, the body weight of birds in the 100-nano-ZnO group was dramatically reduced after 28 days. Relative to the control group, the total antioxidant capability (T-AOC) in serum and liver tissue was significantly higher in the 20-nano-ZnO group at all time points and also significantly higher in the 60- and 100-nano-ZnO groups in serum on days 28 and 35 and in liver tissues on days 21 and 28. Compared with the controls, the activity of copper-zinc superoxide dismutase (Cu-Zn-SOD) was significantly greater in the 60- and 100-nano-ZnO groups in serum on days 28 and 35 and in liver tissues after 21 days. Catalase activity in serum samples was significantly higher in the 20- and 60-nano-ZnO groups relative to the control and 100-nano-ZnO birds, but catalase activity in liver tissue was not affected by different nano-ZnO levels. Malondialdehyde content in serum and liver tissues was significantly reduced in the 20-, 60-, and 100-nano-ZnO groups compared with that in the control group at all time points except day 42. Taken together, our data indicate that appropriate concentration of dietary ZnO nanoparticles improves growth performance and antioxidative capabilities in broilers, and 20 mg/kg nano-ZnO is the optimal concentration.

Training response inhibition to reduce food consumption: Mechanisms, stimulus specificity and appropriate training protocols.

2017-02-01

Training individuals to inhibit their responses towards unhealthy foods has been shown to reduce food intake relative to a control group. Here we aimed to further explore these effects by investigating the role of stimulus devaluation, training protocol, and choice of control group. Restrained eaters received either inhibition or control training using a modified version of either the stop-signal or go/no-go task. Following training we measured implicit attitudes towards food (Study 1) and food consumption (Studies 1 and 2). In Study 1 we used a modified stop-signal training task with increased demands on top-down control (using a tracking procedure and feedback to maintain competition between the stop and go processes). With this task, we found no evidence for an effect of training on implicit attitudes or food consumption, with Bayesian inferential analyses revealing substantial evidence for the null hypothesis. In Study 2 we removed the feedback in the stop-signal training to increase the rate of successful inhibition and revealed a significant effect of both stop-signal and go/no-go training on food intake (compared to double-response and go training, respectively) with a greater difference in consumption in the go/no-go task, compared with the stop-signal task. However, results from an additional passive control group suggest that training effects could be partly caused by increased consumption in the go control group whereas evidence for reduced consumption in the inhibition groups was inconclusive. Our findings therefore support evidence that inhibition training tasks with higher rates of inhibition accuracy are more effective, but prompt caution for interpreting the efficacy of laboratory-based inhibition training as an intervention for behaviour change.

Most interventions aimed at reducing bleeding during myomectomy lack sufficient evidence regarding their effectiveness. Recently, it was reported that intraoperative ascorbic acid administration effectively reduced blood loss during abdominal myomectomy. Therefore, this study aimed to investigate whether intravenous ascorbic acid infusion would affect intraoperative blood loss in women undergoing laparoscopic myomectomy. A randomized, double-blind, parallel-group, placebo-controlled trial including 50 women undergoing laparoscopic myomectomy was conducted. Women with ≤4 myomas, ≤9cm in maximum diameter were eligible. The study:control group ratio was 1:1. Starting 30minutes before anesthesia, 2g of ascorbic acid or a placebo were administered for 2hours intraoperatively. Intraoperative blood loss, the primary endpoint, was calculated as the difference between the volume of fluids acquired from suction and that used for irrigation of the abdominal cavity during surgery using constant values. Among the 50 randomized women, 1 and 3 in the study and control groups, respectively, were excluded due to withdrawal of consent, cancelation of surgery, or non-measurement of the primary endpoint. The baseline and operative characteristics were similar between the study and control groups, as was the intraoperative blood loss (193±204mL vs. 159±193mL, P=0.52). In addition, the operating time (95±29min vs. 110±52min; P=0.50) and decrease in hemoglobin level after surgery (1.9±1.31g/dL vs. 1.4±1.4g/dL; P=0.24) were similar between the study and control groups. Intravenous ascorbic acid infusion did not reduce intraoperative blood loss in women undergoing laparoscopic myomectomy. ClinicalTrials.gov, www.clinicaltrials.gov, NCT01715597.

Purpose To compare the additive effects of two types of non-steroidal anti-inflammatory drugs (NSAIDs), bromfenac 0.1% or ketorolac 0.45%, relative to topical steroid alone in cataract surgery. Materials and Methods A total 91 subjects scheduled to undergo cataract operation were randomized into three groups: Group 1, pre/postoperative bromfenac 0.1%; Group 2, pre/postoperative preservative-free ketorolac 0.45%; and Group 3, postoperative steroid only, as a control. Outcome measures included intraoperative change in pupil size, postoperative anterior chamber inflammation control, change in macular thickness and volume, and ocular surface status after operation. Results Both NSAID groups had smaller intraoperative pupil diameter changes compared to the control group (p<0.05). There was significantly less ocular inflammation 1 week and 1 month postoperatively in both NSAID groups than the control group. The changes in central foveal subfield thickness measured before the operation and at postoperative 1 month were 4.30±4.25, 4.87±6.03, and 12.47±12.24 µm in groups 1 to 3, respectively. In the control group, macular thickness and volume increased more in patients with diabetes mellitus (DM), compared to those without DM. In contrast, in both NSAID groups, NSAIDs significantly reduced macular changes in subgroups of patients with or without DM. Although three ocular surface parameters were worse in group 1 than in group 2, these differences were not significant. Conclusion Adding preoperative and postoperative bromfenac 0.1% or ketorolac 0.45% to topical steroid can reduce intraoperative miosis, postoperative inflammation, and macular changes more effectively than postoperative steroid alone.

Primary nonadherence occurs when new prescriptions are not dispensed. Little is known about how to reduce primary nonadherence. We performed a randomized controlled trial to evaluate an automated system to decrease primary nonadherence to statins for lowering cholesterol. Adult members of Kaiser Permanente Southern California with no history of statin use within the past year who did not fill a statin prescription after 1 to 2 weeks were passively enrolled. The intervention group received automated telephone calls followed 1 week later by letters for continued nonadherence; the control group received no outreach. The primary outcome was a statin dispensed up to 2 weeks after delivery of the letter. Secondary outcomes included refills at intervals up to 1 year. Intervention effectiveness was determined by intent-to-treat analysis and Fisher exact test. Subgroups were examined using logistic regression. There were 2606 participants in the intervention group and 2610 in the control group. Statins were dispensed to 42.3% of intervention participants and 26.0% of control participants (absolute difference, 16.3%; P < .001). The relative risk for the intervention vs control group was 1.63 (95% CI, 1.50-1.76). Intervention effectiveness varied slightly by age (P = .045) but was effective across all age strata. Differences in the frequency of statin dispensations persisted up to 1 year (P < .001). The intervention was effective in reducing primary nonadherence to statin medications. Because of low marginal costs for outreach, this strategy appears feasible for reducing primary nonadherence. This approach may generalize well to other medications and chronic conditions.

Many strategies for labor pain management have been studied, including aromatherapy, which is a noninvasive, alternative medicine used as an adjunct for labor pain control. Nevertheless, the results were contradictory. Therefore, we conducted this study to determine the effectiveness of aromatherapy for reducing pain during labor. A randomized controlled trial was carried out on Thai laboring primigravidae who were a low-risk singleton pregnancy undergoing vaginal delivery. All participants, both study and control group, received standard obstetric care. Aromatherapy was only provided to the study group during the first stage of labor. The women rated their pain intensity by rating scales at different stages of labor. The primary outcome was pain scores and the secondary outcomes were necessity of painkiller usage, labor time, aromatherapy-associated complications, route of delivery, and Apgar scores. A total of 104 women were recruited, 52 in each group. Baseline characteristics and baseline pain scores were comparable. The median pain score of latent and early active phase was lower in the aromatherapy group, 5 vs 6 and 7 vs 8, respectively. The mean differences of pain scores between latent and early active phase and the baseline were significantly lower in the aromatherapy group, 1.88 vs 2.6 (p = 0.010) and 3.82 vs 4.39 (p = 0.031), respectively. Late active phase pain scores and other perinatal outcomes were not significantly different. Aromatherapy is helpful in reducing pain in latent and early active phase, and can probably be used as an adjunctive method for labor pain control without serious side effects.

Nasal packing is usually performed to control bleeding after endoscopic sinus surgery (ESS). Although new packing materials have been developed, they still cause pain. This study was designed to evaluate the effect of lidocaine-soaked packs on pain after ESS. A prospective, randomized, double-blind controlled trial was conducted in 63 patients with CRS undergoing ESS. At the conclusion of the operation, 2% lidocaine-soaked biodegradable synthetic polyurethane foam and saline-soaked polyurethane foam were inserted in both nasal cavities of 31 patients and 32 control patients, respectively. The same lidocaine or saline was reapplied into the nasal packs at postoperative 8 hours. Pain was evaluated using a visual analog scale at postoperative 1, 4, 8, 16, 20, and 24 hour(s). The number of gauze that cleaned the blood around the nose was counted. Heart rate, rhythm, and blood pressures were checked preoperatively and postoperatively to evaluate the influence of lidocaine on vital signs. Postoperative pain decreased in lidocaine group at all of the postoperative time periods (p < 0.05). Lidocaine reduced postoperative bleeding at postoperative 8 and 24 hours. Changes of blood pressure from preoperative values in the lidocaine group were not different from those in the control group (p > 0.05). Heart rate in the lidocaine group was more stable than that in the control group (p < 0.05). Lidocaine-soaked packs significantly reduced postoperative pain without serious changes on vital sign. These findings suggest that topical lidocaine application to nasal packs could be a useful method to reduce pain during the early postoperative period after ESS.

Fumonisins (FBs) are mycotoxins produced by Fusarium fungi. This study aimed to investigate the effect of these feed contaminants on the intestinal morphology and microbiota composition, and to evaluate whether FBs predispose broilers to necrotic enteritis. One-day-old broiler chicks were divided into a group fed a control diet, and a group fed a FBs contaminated diet (18.6 mg FB1+FB2/kg feed). A significant increase in the plasma sphinganine/sphingosine ratio in the FBs-treated group (0.21 ± 0.016) compared to the control (0.14 ± 0.014) indicated disturbance of the sphingolipid biosynthesis. Furthermore, villus height and crypt depth of the ileum was significantly reduced by FBs. Denaturing gradient gel electrophoresis showed a shift in the microbiota composition in the ileum in the FBs group compared to the control. A reduced presence of low-GC containing operational taxonomic units in ileal digesta of birds exposed to FBs was demonstrated, and identified as a reduced abundance of Candidatus Savagella and Lactobaccilus spp. Quantification of total Clostridium perfringens in these ileal samples, previous to experimental infection, using cpa gene (alpha toxin) quantification by qPCR showed an increase in C. perfringens in chickens fed a FBs contaminated diet compared to control (7.5 ± 0.30 versus 6.3 ± 0.24 log10 copies/g intestinal content). After C. perfringens challenge, a higher percentage of birds developed subclinical necrotic enteritis in the group fed a FBs contaminated diet as compared to the control (44.9 ± 2.22% versus 29.8 ± 5.46%).

Work stress is a major contributor to absenteeism and reduced work productivity. A randomised and controlled study in employee-volunteers (with Perceived Stress Scale [PSS-14]>22) was performed to assess a mindfulness program based on brief integrated mindfulness practices (M-PBI) with the aim of reducing stress in the workplace. The PSS-14 of the employees before and after 8-weeks M-PBI program, as well as after a 20-week follow-up, was assessed (primary endpoint). The employees also carried the following questionnaires (secondary endpoints): Five Facet Mindfulness Questionnaire (FFMQ), Self-Compassion Scale (SCS), Experiences Questionnaire-Decentering (EQ-D), and Maslach Burnout Inventory-General Survey (MBI-GS). Heart Rate Variability (HRV) was measured during each session in a subgroup of employees (n = 10) of the interventional group randomly selected. A total of 40 employees (77.5% female median [SD] age of 36.6 [5.6] years) took part in this study: 21 and 19 in the intervention and control group, respectively. No differences in baseline characteristics were encountered between the groups. Results show a significant decrease in stress and increase in mindfulness over time in the intervention group (PSS-14 and FFMQ; p < 0.05 both). Additionally, an improvement in decentering (EQ-D), self-compassion (SCS) and burnout (MBI-GS) were also observed compared to the control group (p < 0.05 in all). HRV measurement also showed an improvement. In conclusion, a brief practices, 8-weeks M-BIP program is an effective tool to quickly reduce stress and improve well-being in a workplace.

Aims Hemodynamic instability occurs following cardiac arrest and is associated with high mortality during the post-cardiac period. Urocortin is a novel peptide and a member of the corticotrophin-releasing factor family. Urocortin has the potential to improve acute cardiac dysfunction, as well as to reduce the myocardial damage sustained after ischemia reperfusion injury. The effects of urocortin in post-cardiac arrest myocardial dysfunction remain unclear. Methods and Results We developed a preclinical cardiac arrest model and investigated the effects of urocortin. After cardiac arrest induced by 6.5 min asphyxia, male Wistar rats were resuscitated and randomized to either the urocortin treatment group or the control group. Urocortin (10 μg/kg) was administrated intravenously upon onset of resuscitation in the experimental group. The rate of return of spontaneous circulation (ROSC) was similar between the urocortin group (76%) and the control group (72%) after resuscitation. The left ventricular systolic (dP/dt40) and diastolic (maximal negative dP/dt) functions, and cardiac output, were ameliorated within 4 h after ROSC in the urocortin-treated group compared to the control group (P<0.01). The neurological function of surviving animals was better at 6 h after ROSC in the urocortin-treated group (p = 0.023). The 72-h survival rate was greater in the urocortin-treated group compared to the control group (p = 0.044 by log-rank test). Cardiomyocyte apoptosis was lower in the urocortin-treated group (39.9±8.6 vs. 17.5±4.6% of TUNEL positive nuclei, P<0.05) with significantly increased Akt, ERK and STAT-3 activation and phosphorylation in the myocardium (P<0.05). Conclusions Urocortin treatment can improve acute hemodynamic instability as well as reducing myocardial damage in post-cardiac arrest myocardial dysfunction. PMID:27832152

No study has tested the effectiveness of individualized cognitive behavioral therapy (CBT) interventions to reduce persistent nausea, pain, anxiety, and fatigue in patients on continuous antiretroviral therapy (ART). Our objective was to determine if CBT could reduce nausea, pain, anxiety, and fatigue in patients with HIV on ART. Men ages 40 to 56 years on ART (n = 18) at a suburban HIV clinic were randomly assigned to a control group or the CBT intervention. Usual adherence education and side-effect management were provided to both groups. Symptoms, health perception, medication adherence, and side-effect-reducing medication use were measured at four time points over 3 months. Participants in the intervention group rated usual fatigue and worst fatigue at 60 days, and nausea duration at 90 days significantly lower than controls (p < .05). Brief CBT training may reduce fatigue and nausea in patients with HIV undergoing ART. Copyright © 2016 Association of Nurses in AIDS Care. Published by Elsevier Inc. All rights reserved.

Monetary incentives for reduced electricity consumption by residents living in mass-metered university dormitories were provided via a contest and contest-raffle. In the contest, reduced electricity consumption of a group of students was reinforced with group consequences. In the contest-raffle, reduced electricity consumption of a group of students was reinforced with individual consequences. A control condition measured normal fluctuations in electricity use. Electricity consumption by residents in the contest and contest-raffle was consistently lower than consumption by residents in the control condition throughout the treatment period. Also, consumption by male residents was lower than consumption by female residents. Analysis of electricitymore » consumption during a post-treatment baseline period suggested residual effects due to the contest and contest-raffle. Residents' reactions to the contest and contest-raffle were assessed through telephone interviews. It was suggested that energy conservation programs incorporate elements based on behavioral technology as well as physical technology.« less

Joint Moment-Angle Properties of the Hip Extensors in Subjects With and Without Patellofemoral Pain.

Kindel, Curtis; Challis, John

2018-04-01

Strength deficits of hip extension in individuals with patellofemoral syndrome are commonly reported in literature. No literature to date has examined these deficits with variable positions of the knee and hip; altering knee angle alters the length and therefore potentially the force produced by the biarticular muscles. Beyond strength, neuromuscular control can also be assessed through the analysis of isometric joint moment steadiness. Subjects consisted of a group of individuals with patellofemoral syndrome (n = 9), and a group of age- and size-matched controls with no symptoms (n = 9). Maximum isometric joint moments for hip extension were measured at 4 points within the joint's range of motion, at 2 different knee positions (0° and 90°) for each group. The joint moment signals were analyzed by computing signal Coefficient of Variation (CV). The results indicate that no significant differences were found between the groups of subjects for the hip extension moments when the knee was extended. However, there was a significant difference between the groups for the joint moments of hip extension with the knee flexed at all 4 hip positions. Results also showed hip extension CV values to be significantly higher in the patellofemoral group compared with the control group, indicating greater signal noise and therefore poorer neuromuscular control of the hip extensor musculature. This study demonstrated that individuals with patellofemoral syndrome have reduced hip extension strength and reduced neuromuscular control with the knee flexed compared with a control group. These results have implications for the etiology of patellofemoral syndrome and its rehabilitation.

From one hand, depression is one of the symptoms that occur after abstinence from methamphetamine. On the other people living with HIV/AIDS are in isolation due to the nature of their illness and depression is one of the most common mental health problems they experience. This study was aimed at determining the effectiveness of saffron on reducing depression among recovered consumers of methamphetamine living with HIV/AIDS. The design of this study was semi-experimental with pre-test, post-test and control (placebo) groups. The statistical population consisted of all recovered consumers of methamphetamine living with HIV/AIDS who were referred to the Positive Club. Fifty-seven (57) recovered consumers of methamphetamine, living with HIV/AIDS, were selected by convenience sampling method. They were randomly assigned to an experimental (saffron) group and a control (placebo) group. The experimental group received 30 ml of saffron per day for 8 weeks, whereas the control (placebo) group received placebo the same way. BDI-II was used in this study as a measurement instrument. ANCOVA models were used for statistical inference. The findings showed that saffron and its ingredients had been effective in reducing depression among this group (P < 0.05). In fact, saffron with its active ingredients (Crusin and Saffranal) by serotonin and dopamine secretion in the brain, help in reducing depression among recovered consumers of methamphetamine living with HIV/AIDS.

Previous studies in humans have shown that the cacao polyphenols, (-)-epicatechin and its oligomers, prevent in vitro and ex vivo low-density lipoprotein oxidation mediated by free radical generators and metal ions and also reduce plasma LDL-cholesterol levels. The aim of this study was to examine the effects of cacao polyphenols on the development of atherosclerosis in apolipoprotein E-deficient (-/-) mice. Mice aged 8 weeks (n = 90) were randomized into three groups, and fed either normal mouse chow (controls) or chow supplemented with 0.25 or 0.40 % cacao polyphenols for 16 weeks. The mean plaque area in cross-sections of the brachiocephalic trunk was measured and found to be lower in the 0.25 % cacao polyphenol group than in the control group (p < 0.05). Pathological observations showed that accumulation of cholesterol crystals in the plaque area was greater in the control group compared with the 0.40 % cacao polyphenol group (p < 0.05). Immunochemical staining in the 0.25 and 0.40 % groups showed that expression of the cell adhesion molecules (VCAM-1 and ICAM-1) and production of oxidative stress markers (4-hydroxynonenal, hexanoyl-lysine, and dityrosine) were reduced in cross-sections of the brachiocephalic trunk. These results suggest that cacao polyphenols inhibit the development of atherosclerosis in apolipoprotein E-deficient (-/-) mice by reducing oxidative stress and inflammatory responses.

The most appropriate route of tranexamic acid administration is controversial. In the current study, we compared the efficacy of intravenous (IV) and topical intra-articular tranexamic acid in reducing blood loss and transfusion rate in patients who underwent primary total knee arthroplasty. One hundred twenty 120 patients were scheduled to undergo primary total knee arthroplasty. Patients were randomly allocated to three equal groups: IV tranexamic acid (500 mg), topical tranexamic acid (3 g in 100 mL normal saline) and the control. In the topical group, half of the volume was used to irrigate the joint and the other half was injected intra-articularly. The volume of blood loss, hemoglobin (Hb) level at 24 hours postoperative, and rate of transfusion was compared between groups. The blood loss and Hb level were significantly greater and lower in the control group, respectively (P=0.031). Also, the rate of transfusion was significantly greater in the control group (P=0.013). However, IV and topical groups did not differ significantly in terms of measured variables. No patient experienced a thromboembolic event in our study. Tranexamic acid is a useful antifibrinolytic drug to reduce postoperative blood loss, Hb drop, and rate of blood transfusion in patients undergoing total knee arthroplasty. The route of tranexamic acid administration did not affect the efficacy and safety.

Few effective treatments are available for severe forms of bulimia nervosa, which are accompanied by malnutrition, anxiety, and depressive mood. We previously showed in an open study that nasogastric tube feeding (TF) reduced binges and purging in patients with anorexia nervosa. This prospective randomized trial compared bulimia patients in two treatment groups: one group received TF at home, together with psychotherapy, nutritional counseling and a support group while the control group received only psychotherapy, nutritional counseling, and a support group. Patients in the first group underwent TF for 8 weeks (exclusively for 10 days and associated with meals thereafter). Assessment was based on clinical examination, laboratory results, and a variety of questionnaires (our in-house instrument for measuring binge and vomiting episodes, eating disorder inventory, Beck's depression inventory and the Hamilton rating scale for anxiety), all performed at the onset of treatment and at 8 days, 8 weeks (i.e., the end of TF), and 3 months after treatment began. Binges and vomiting disappeared faster and more frequently in TF patients than in the control group: 65% versus 29% (p<0.01). Three months later, these remained less frequent in the TF group than among controls (52% versus 33%, p=0.064). Nutritional status, depression, and anxiety improved more among the TF than control subjects (p<0.05). Tube feeding was effective in these patients with bulimia nervosa, reducing the number of binge and vomiting episodes and improving nutritional status and mood.

The aim of this study was to determine the effect of a high-fat diet (HFD) on oocyte maturation and quality in a mouse model. Female BALB/c mice were allocated to one of the following groups: (a) control group (n = 40), which received a controlled diet; or (b) HFD group (n = 40), which received an HFD for 12 weeks. Sections of the ovary were examined histologically. The number of follicles and corpora lutea were counted. In vitro maturation and in vitro fertilisation (IVF) were assessed in germinal vesicle (GV) and metaphase II (MII) oocytes, respectively. The expression of bone morphogenetic protein 15 (BMP15) and leptin receptor genes in GV and MII oocytes was evaluated using reverse transcription real-time polymerase chain reactions. In the HFD group, there was a decreased number of primordial and Graafian follicles, as well as corpora lutea (p < 0.05). The rate of oocyte development to the MII stage was also reduced (p < 0.001). Cumulus expansion was observed more frequently in the control group than the HFD group (p < 0.05). The IVF rate in the HFD group was lower than that in the control group (p < 0.05). In the HFD group, BMP15 and leptin receptor genes were upregulated in the GV stage (p > 0.05) and MII stage (p < 0.05), compared to the control group. An HFD reduces folliculogenesis in the primordial and Graafian stages, in vitro maturation and in vitro fertilisation rates, as well as oocyte quality in mice.

Although the toxicity of melamine to the kidneys and testes is well known, few studies have investigated the effects of melamine on female reproductive organs. Therefore, this study explores the effects of oral administration melamine or melamine and cyanuric acid for 28 days on the ovaries of female rats. Rats that were exposed to the mixture exhibited reduced ovarian and uterine weights, a shorter estrous cycle, and reduced serum estrogen and progesterone levels compared to rats that were exposed to melamine and control rats. Furthermore, morphological analysis revealed pathological changes in the ovaries of rats exposed to melamine or the mixture, such as more atretic follicles and necrosis of oocytes and granulosa cells. TUNEL staining revealed that the exposed groups had a higher proportion of TUNEL-positive granulosa cells than the control group, and the mRNA expressions of SOD1, GPX1, GPX2, P450scc, 17β-HSD I, and 17β-HSD II were reduced in the exposure groups compared with the control group. These results indicated that exposure to melamine alone or to the melamine-cyanuric acid mixture could damage the ovaries in rats. PMID:26866683

Work-related musculoskeletal disorders (WMSDs) are the main causes of pain, suffering, absenteeism, disability and reduction in productivity. This research aims to determine the role of training intervention based on protection motivation theory in reducing WMSDs and promoting productivity. The conducted study was based on a quasi-experimental design (control) that was carried out on 158 employees of the Kabl Khodro factory which were divided into two groups of 79 people. After splitting the 158 workers, an experimental and control group was formed. The data collection instruments were made up of two questionnaires and were analysed using a quick exposure check (QEC) method. Before intervention in both the experimental and control groups, there were no significant differences among the average protection motivation theory constructs, productivity and QEC scores (p < 0.05). However, following training intervention there was a significant increase in these factors within the investigated group apart from the perceived response costs and efficacy. The conducted study shows that ergonomic training based on the protection motivation theory is effective in reducing musculoskeletal risk factors and that increased knowledge of the subject can lead to an increase in productivity.

Hypertrophic scars are caused by trauma or burn injuries to the deep dermis and can cause cosmetic disfigurement and psychological issues. Studies suggest that M2-like macrophages are pro-fibrotic and contribute to hypertrophic scar formation. A previous study from our lab showed that M2 macrophages were present in developing hypertrophic scar tissues in vivo at 3-4 weeks after wounding. In this study, the effect of systemic macrophage depletion on scar formation was explored at subacute phase of wound healing. Thirty-six athymic nude mice that received human skin transplants were randomly divided into macrophage depletion group and control group. The former received intraperitoneal injections of clodronate liposomes while the controls received sterile saline injections on day 7, 10, and 13 postgrafting. Wound area, scar thickness, collagen abundance and collagen bundle structure, mast cell infiltration, myofibroblast formation, M1, and M2 macrophages together with gene expression of M1 and M2 related factors in the grafted skin were investigated at 2, 4, and 8 weeks postgrafting. The transplanted human skin from the control group developed contracted, elevated, and thickened scars while the grafted skin from the depletion group healed with significant less contraction and elevation. Significant reductions in myofibroblast number, collagen synthesis, and hypertrophic fiber morphology as well as mast cell infiltration were observed in the depletion group compared to the control group. Macrophage depletion significantly reduced M1 and M2 macrophage number in the depletion group 2 weeks postgrafting as compared to the control group. These findings suggest that systemic macrophage depletion in subacute phase of wound healing reduces scar formation, which provides evidence for the pro-fibrotic role of macrophages in fibrosis of human skin as well as insight into the potential benefits of specifically depleting M2 macrophages in vivo. © 2016 by the Wound Healing Society.

The sample consisted of 1- to 12-month-old infants registered in a family health center in Istanbul, Turkey, for healthcare follow-up. A total of 60 infants who met the criteria of the sample group were included in the study; 30 infants constituted the reflexology group and the other 30 constituted the control group. Although questionnaire forms were used to determine the descriptive characteristics of infant-mother pairs, the Face, Legs, Activity, Cry, Consolability (FLACC) Pain Assessment Scale was used to evaluate pain level. Infants in the reflexology group received reflexology treatment for an average of 20-30 minutes before vaccination, depending on the physical size of the infant's foot. Pain, heart rate, oxygen saturation levels, and crying periods of infants in the reflexology and control groups were evaluated before and after vaccination. The FLACC pain score was observed to be statistically similar between groups. After reflexology was applied to infants in the reflexology group before vaccination, it was determined that the pain score was reduced to .50 ± 1.14. In the examination performed after vaccination, FLACC pain score was found to be 5.47 ± 2.11 in the reflexology group and 9.63 ± .85 in the control group. A statistically significant difference was observed between the mean FLACC pain scores of infants in the reflexology and control groups (p = .000). The infants in the reflexology group also had lower heart rates, higher oxygen saturation, and shorter crying periods than the infants in the control group (p <.001). Reflexology before vaccine reduced the pain level experienced after vaccination. Future research needs to explore different interventional practices. © 2015 Sigma Theta Tau International.

To investigate the mechanism of exogenous adiponectin in the prevention of no-reflow phenomenon in type 2 diabetic (T2DM) patients with acute myocardial infarction (AMI) during percutaneous coronary intervention (PCI) treatment. 66 patients were randomly divided into control group and observation group, 33 cases in each group. According to the percutaneous coronary intervention (PCI) emergency treatment principle, patients from the control group were treated with an intracoronary injection of adenosine combined with a micro-pump intravenous infusion of tirofiban. Patients from the observation group were injected with exogenous adiponectin in addition to the adenosine and tirofiban treatments. There were no significant differences in gender, age, location of the target lesion, degree of stenosis, stent implantation number, length and the inner diameter between control and observation group (p > 0.05). Lower frequent of slow blood flow and no-reflow and shorter interventional procedures were observed in observation group compared with those of control group (p < 0.05). Moreover, the increase of plasma creatine kinase (CK-MB) in patients of observation group was lower than that of the patients in control group (p < 0.05). In addition, the levels of troponin-I (cTnI), IL-6, TNF- α, endothelin-1 (ET-1), vascular endothelial adhesion molecular I (VCAM-1) and bax/Bcl-2 were significantly lower in observation group than those in control (p < 0.05). Furthermore, the occurrence of major adverse cardiac events (MACE) during a 12-month follow-up was significantly lower in the observation group than that of control (p < 0.05). Exogenous adiponectin further reduced the no-reflow phenomenon during PCI treatment of the patients with T2DM combined with AMI. The function of exogenous adiponectin is associated with the reduced myocardial and endothelial cell injury and the inhibited inflammation and apoptosis. The application of exogenous adiponectin can significantly improve the clinical outcomes.

Safety of emergency intubation may be improved by standardising equipment preparation; the efficacy of cognitive aids is unknown. This randomised controlled trial compared no cognitive aid (control) with the use of a checklist or picture template for emergency airway equipment preparation in the Emergency Department of The Royal Children's Hospital, Melbourne. Sixty-three participants were recruited, 21 randomised to each group. Equal numbers of nursing, junior medical, and senior medical staff were included in each group. Compared to controls, the checklist or template group had significantly lower equipment omission rates (median 30% IQR 20-40% control, median 10% IQR 5-10 % checklist, median 10% IQR 5-20% template; p < 0.05). The combined omission rate and sizing error rate was lower using a checklist or template (median 35 % IQR 30-45 % control, median 15% IQR 10-20% checklist, median 15% IQR 10-30% template; p < 0.05). The template group had less variation in equipment location compared to checklist or controls. There was no significant difference in preparation time in controls (mean 3 min 14 s sd 56 s) compared to checklist (mean 3 min 46 s sd 1 min 15 s) or template (mean 3 min 6 s sd 49 s; p = 0.06). Template use reduces variation in airway equipment location during preparation foremergency intubation, with an equivalent reduction in equipment omission rate to the use of a checklist. The use of a template for equipment preparation and a checklist for team, patient, and monitoring preparation may provide the best combination of both cognitive aids. The use of a cognitive aid for emergency airway equipment preparation reduces errors of omission. Template utilisation reduces variation in equipment location.

Hypertension often clusters with metabolic risk factors and its optimal treatment may involve a number of changes in lifestyle. Nurse-led care regarding lifestyle change may improve outcomes in cardiovascular disease prevention involving. To examine if lifestyle guidance given by a nurse improved components of the metabolic syndrome including blood pressure, lipids and waist circumference. Subjects that participated in a health screening with systolic blood pressure 140-169 mm Hg and diastolic blood pressure 90-99 mm Hg at a minimum of three separate readings treated or not treated with antihypertensive drugs were randomly allocated either to monthly nurse-led lifestyle counselling (intervention group, N=31) or to conventional primary care (control group, N=20) to be followed by lifestyle counselling. The mean (S.D.) baseline and end of study blood pressure was 157 (9)/94 (6) mm Hg and 147 (9)/91 (8) mm Hg, respectively, in the intervention group versus 153 (9)/94 (4) and 143 (10)/92 (8) mm Hg, respectively, in the control group (NS between the groups). Waist circumference increased significantly between baseline and 6 months in the control but not in the intervention (mean difference between the groups, 3.1 cm [95% CI 1.2-5.0], p=0.04) and serum triglyceride concentrations were reduced in the intervention compared with the control group (mean difference, 0.56 mmol/l [95% CI 0.22-0.90], p=0.03). The number of risk factors of the metabolic syndrome was 2.1 (S.D. 1.1) at baseline and 2.6 (S.D. 1.2) at 6 months in the control group versus 2.2 (S.D. 1.1) and 1.9 (S.D. 1.0), respectively, in the intervention group (p=0.01). Change in triglycerides was correlated with change in weight (Pearson's correlation coefficient=0.73, p=0.001) and waist circumference (Pearson's correlation coefficient=0.63, p=0.009) in the control group. Nurse counselling did not reduce blood pressure but was associated with a lesser gain in waist circumference and reduced triglyceride concentrations. Metabolic risk factors may worsen rapidly in patients with mild hypertension in the waiting period for lifestyle intervention.

To evaluate the effect of a nurse-conducted intervention on excessive drinkers. Randomized, controlled trial. Vårby Health Centre, Stockholm. The intervention group visited a nurse three times during a 12-month period. The controls met once with a general practitioner (GP). Patients were recruited at a health screening on the basis of a raised gamma-glutamyl transferase (GGT). Of 2338 subjects, aged 25-54 years, 222 had a screening GGT of > or = 0.9 mukat/l. 100 were randomized to the treatment and 122 to the control group. GGT, self-reported alcohol consumption (g/week), sickness allowance and use of health care. After 2 years a reduction of GGT from 1.52 to 1.21 mukat/l (p = 0.02) had occurred in the treatment group. The controls increased their mean level of GGT from 1.75 to 2.16 mukat/l. Mean weekly alcohol consumption in the intervention group was reduced from 337 to 228 g/week (p = 0.02). The controls did not quantify their alcohol consumption initially, but reported a reduced weekly consumption at follow-up. The intervention had an impact on GGT and self-reported consumption. The controls also reported decreased consumption possibly because their appointment with the GP functioned as a very brief intervention.

Despite efficacious pharmacological and behavioral treatments, most smokers attempt to quit without assistance and fail to quit. Mindfulness practice may be useful in smoking cessation. This ecological momentary assessment (EMA) study was a pilot parallel group randomized controlled trial of a brief mindfulness practice (Brief-MP) intervention on self-reported smoking behavior delivered to smokers on a Personal Digital Assistant (PDA) in the field. Adult community smokers (N = 44) were randomly assigned to a Brief-MP (n = 24) or Control (sham meditation; n = 20) group. Participants were instructed to smoke as much or as little as they liked. Participants carried a PDA for 2 weeks and were instructed to initiate 20 minutes of meditation (or control) training on the PDA daily, completing an assessment of cognitive and affective processes immediately afterwards. Additionally, they completed assessments at random times up to four times per day. Primary outcome variables were negative affect, craving, and cigarettes smoked per day, all self-reported. Thirty-seven participants provided EMA data totaling 1874 assessments. Linear Mixed Model analyses on EMA data revealed that Brief-MP (vs. Control) reduced overall negative affect, F(1, 1798) = 13.8, P = .0002; reduced craving immediately post-meditation, (Group × Assessment Type interaction, F(2, 1796) = 12.3, P = .0001); and reduced cigarettes smoked per day over time (Group × Day interaction, F(1, 436) = 5.50, P = .01). Brief-MP administered in the field reduced negative affect, craving, and cigarette use, suggesting it may be a useful treatment.

Importance Healthcare professionals commonly recommend increased water consumption, typically to 8 cups/d, as part of a weight-reducing diet. However, this recommendation is based on limited evidence and virtually no experimental data in the pediatric age range. Objective The aim of this study was to compare two standard weight-loss diets, either with (Water) or without (Control) additional advice and behavioral support to increase habitual water intake to 8 cups/d. Design 6-month randomized controlled parallel-group design. Setting The trial was conducted at Boston Children’s Hospital, Boston, Massachusetts, between February 2011 and June 2014. Participants 38 overweight and obese adolescents who reported drinking ≤4 cups of water/d. Intervention Both groups received similar weight-reducing interventions, differentiated by water messages but controlled for other dietary recommendations and treatment intensity. The interventions included dietary counseling, daily text messages, and a cookbook with health guides. To support adherence to 8 cups water/d, the Water group received well-defined water messages through counseling and daily text messages, a water bottle, and a water pitcher with filters. The Control group received no specific advice on water consumption. Main Outcome and Measures Primary outcome was 6-month change in body mass index (BMI) z-score. Results All randomized participants completed the study. Both groups reported drinking ~2 cups/d water at baseline. Self-reported change in water intake was greater in the Water Group compared to the Control Group (difference between groups, 1.6; 95% CI, 0.2 to 3.0 cups/d; P=0.03). The 6-month change in BMI z-score did not differ between groups (−0.0; 95% CI, −0.1 to 0.1; P=0.88). Conclusions and Relevance Contrary to hypothesis, advice and behavioral supports to consume 8 cups water/d in the context of a weight-reducing diet did not affect body weight among overweight and obese adolescents. Despite intensive behavior supports, few achieved the 8 cups/d water target. Environmental interventions to reduce barriers to water consumption at school may be necessary in future research of feasibility and effectiveness to achieve the target of an 8-cup/d intake of water in adolescents.

Background Water level management has been suggested as a potential tool to reduce malaria around large reservoirs. However, no field-based test has been conducted to assess the effect of water level management on mosquito larval abundance in African settings. The objective of the present study is to evaluate the effects of water level drawdown rates on mosquito larval abundance. Methods Twelve experimental dams were constructed on the foreshore of the Koka Dam in Ethiopia. These were grouped into four daily water drawdown treatments, each with three replicates: no water-level drawdown (Group 1; Control), 10 mm.d-1 (Group 2), 15 mm.d-1 (Group 3) and 20 mm.d-1 (Group 4). Larval sampling was conducted weekly for a period of 6 weeks each in the main malaria transmission season (October to November 2013) and subsequent dry season (February to March 2014). Larval densities were compared among treatments over time using repeated measures Analysis of Variance (ANOVA). Results A total of 284 Anopheles mosquito larvae were collected from the experimental dams during the study period. Most (63.4%; n = 180) were collected during the main malaria transmission season while the remaining (36.6%; n = 104) were collected during the dry season. Larvae comprised four Anopheles species, dominated by Anopheles arabiensis (48.1% of total larval samples; n = 136) and An. pharoensis (33.2%; n = 94). Mean larval density was highest in control treatment dams with stable water levels throughout the study, and decreased significantly (P < 0.05) with increasing water drawdown rates in both seasons. During the main transmission season, anopheline larval density was generally lower by 30%, 70% and 84% in Groups 2, Group 3 and Group 4, respectively, compared with the control dams (Group 1). In the dry season, larval density was reduced by 45%, 70% and 84% in Groups 2, Group 3 and Group 4, respectively, when compared to the control dams. Conclusion Increased water drawdown rates were associated with lower mosquito larval abundance. Water level management could thus serve as a potential control measure for malaria vectors around reservoirs by regulating the persistence of shallow shoreline breeding habitats. Dam operators and water resource managers should consider incorporating water level management as a malaria control mechanism into routine dam operations to manage the risk of malaria transmission to human populations around reservoirs.

While waiting for surgery, patients often exhibit fear and anxiety. Music is thought to be an alternative to medication to relieve anxiety. However, due to concerns about infection control, devices other than headphones may be considered for this purpose. The purpose of this study was to determine the anxiety-relieving effect of broadcast versus headphone music playing for patients awaiting surgery. A randomized controlled clinical study. The waiting area of an operating theater of a metropolitan teach hospital in Taiwan. Alert adult with age between 20 and 65 years old waiting for surgery without premedications. A total of 167 patients were randomly assigned to the headphone, broadcast and control groups. Both the headphone and the broadcast groups were provided with the same instrumental music, while the control group did not listen to any music. The tools for measuring anxiety were visual analogue scale (VAS) ranging from "not anxious at all" to "extremely anxious" and heart rate variability (HRV). The VAS score exhibited a significant decrease for both the headphone and broadcast groups. The low frequency and low-to-high frequency LF/HF ratio of the broadcast and headphone groups were significantly lower than those of the control group. None of the heart rate variables showed significant differences between the broadcast group and the headphone group. Both headphone and broadcast music are effective for reducing the preoperative patient's anxiety in the waiting room. In order to take infection control into account, broadcast speakers can substitute for headphones for playing music to lower the anxiety level of patients waiting for surgery.

Jensen, Anne M; Ramasamy, Adaikalavan; Hall, Michael W

General flexibility is a key component of health, well-being, and general physical conditioning. Reduced flexibility has both physical and mental/emotional etiologies and can lead to musculoskeletal injuries and athletic underperformance. Few studies have tested the effectiveness of a mind-body therapy on general flexibility. The aim of this study was to investigate if Neuro Emotional Technique® (NET), a mind-body technique shown to be effective in reducing stress, can also improve general flexibility. The sit-and-reach test (SR) score was used as a measure of general flexibility. Forty-five healthy participants were recruited from the general population and assessed for their initial SR score before being randomly allocated to receive (a) two 20-minute sessions of NET (experimental group); (b) two 20-minute sessions of stretching instruction (active control group); or (c) no intervention or instruction (passive control group). After intervention, the participants were reassessed in a similar manner by the same blind assessor. The participants also answered questions about demographics, usual water and caffeine consumption, and activity level, and they completed an anxiety/mood psychometric preintervention and postintervention. The mean (SD) change in the SR score was +3.1 cm (2.5) in the NET group, +1.2 cm (2.3) in the active control group and +1.0 cm (2.6) in the passive control group. Although all the 3 groups showed some improvement, the improvement in the NET group was statistically significant when compared with that of either the passive controls (p = 0.015) or the active controls (p = 0.021). This study suggests that NET could provide an effective treatment in improving general flexibility. A larger study is required to confirm these findings and also to assess longer term effectiveness of this therapy on general flexibility.

Responses to life stressors are associated with negative behaviors that may increase risk for illness and injury. The effect of high intensity exercise in reducing reactivity to psychological stress has been well documented among older people. The purpose of this study was to ascertain the effect of weight-training versus aerobic dance on psychological stress in college students. 45 students participated in a weight-training course, 35 students participated in aerobic dance classes, and 34 students served as a control group. The Survey of Recent Life Experiences was used to appraise stressfulness of current experiences before and after exercise intervention. On immediate retest after 8 wk. of weight-training perceived stress was significantly reduced when compared with an 8-wk. aerobic dance program, but there were no significant differences between the control group and the weight-training group or the aerobic dance group. These results suggest that a regular routine of low intensity exercise such as weight-training may reduce perceived stress on an immediate test.

Chromium is an essential mineral that contributes to normal glucose function and lipid metabolism. This study evaluated the effect of chromium picolinate (CrPic) supplementation in patients with type 2 diabetes mellitus (T2DM). A four month controlled, single blind, randomized trial was performed with 71 patients with poorly controlled (hemoglobin A1c [HbA1c]>7%) T2DM divided into 2 groups: Control (n=39, using placebo), and supplemented (n=32, using 600μg/day CrPic). All patients received nutritional guidance according to the American Diabetes Association (ADA), and kept using prescribed medications. Fasting and postprandial glucose, HbA1c, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides and serum ferritin were evaluated. CrPic supplementation significantly reduced the fasting glucose concentration (-31.0mg/dL supplemented group; -14.0mg/dL control group; p<0.05, post- vs. pre-treatment, in each group) and postprandial glucose concentration (-37.0mg/dL in the supplemented group; -11.5 mg/dL in the control group; p<0.05). HbA1c values were also significantly reduced in both groups (p<0.001, comparing post- vs. pre-treatment groups). Post-treatment HbA1c values in supplemented patients were significantly lower than those of control patients. HbA1c lowering in the supplemented group (-1.90), and in the control group (-1.00), was also significant, comparing pre- and post-treatment values, for each group (p<0.001 and p<0.05, respectively). CrPic increased serum chromium concentrations (p<0.001), when comparing the supplemented group before and after supplementation. No significant difference in lipid profile was observed in the supplemented group; however, total cholesterol, HDL-c and LDL-c were significantly lowered, comparing pre- and post-treatment period, in the control group (p<0.05). CrPic supplementation had a beneficial effect on glycemic control in patients with poorly controlled T2DM, without affecting the lipid profile. Additional studies are necessary to investigate the effect of long-term CrPic supplementation. Copyright © 2015 Elsevier GmbH. All rights reserved.

Exercise is an important component of obesity-associated disorders and has been shown to reduce markers of nonalcoholic fatty liver disease (NAFLD). However, little is known about how these effects are influenced by alcohol intake. The authors performed a randomized controlled trial to investigate the effects of exercise on hepatic triglyceride content (HTGC) and metabolism in overweight or obese patients who consume alcohol. The authors performed a prospective study of 27 patients (mean 54 ± 11 years of age, body mass index [BMI] 31 ± 4 kg/m 2 ) with >5% HTGC in the United Kingdom, consuming alcohol (mean 221 ± 75 g/week). Anthropometry, body composition, HTGC, and abdominal fat were measured using plethysmography and magnetic resonance imaging. Subjects were assigned to groups that exercised (3 times/week on nonconsecutive days) for 12 weeks (n = 14) or continued standard care (control group, n = 13), maintaining baseline weight and alcohol consumption. The exercise program consisted of aerobic exercise (static cycling) and a circuit of resistance exercise (free weights and machines). Patients were examined at baseline and at 12 weeks; data collected on HTGC, body composition, metabolic control, circulating inflammatory, and fibrosis markers were assessed at baseline and at 12 weeks. Between-group differences were evaluated using an unpaired t test and within-group differences using a paired t test. The primary outcomes for this study were changes in HTGC between baseline and 12 weeks. After 12 weeks, there was no significant difference between the exercise and control groups in HTGC (reduction of 0.1% ± 2.1% in exercisers vs increase of 0.5 ± 2.1% in control group; P > .05). At week 12, the exercise group had significant reductions in subcutaneous fat (loss of 23 ± 28 cm 2 in the exercisers vs increase of 12 ± 19 cm 2 in the control group; P < .01), and whole body fat (loss of 2.1 ± 1.1 kg in the exercisers vs increase of 0.2 ± 2.1 kg; P < .01). The exercise group also had a significantly greater increase in lean body mass (increase of 1.9 ± 1.4 kg for the exercisers vs increase of 0.7 ± 1.5 kg for the control group; P < .01) and a significantly greater reduction in level of cytokeratin 18 (reduction of 49 ± 82 U/L in exercisers vs increase of 17 ± 38 U/L in control group; P < .05). There were no differences between groups in changes in metabolic factors or markers of inflammation. In a randomized controlled trial of obese individuals who consume alcohol, exercise significantly improved body composition and reduced hepatocyte apoptosis (cytokeratin 18), but did not reduce HTGC. This finding could indicate that alcohol consumption reduces the effects of exercise on NAFLD observed in previous studies. Clinical care teams should look to use exercise as part of the management strategy for people consuming alcohol, but optimal benefit may be as an adjunct to alcohol reduction and weight management strategies.

Abstract Individuals with Autism Spectrum Disorder (ASD) are characterized by severe deficits in social communication, whereby the nature of their impairments in emotional prosody processing have yet to be specified. Here, we investigated emotional prosody processing in individuals with ASD and controls with novel, lifelike behavioral and neuroimaging paradigms. Compared to controls, individuals with ASD showed reduced emotional prosody recognition accuracy on a behavioral task. On the neural level, individuals with ASD displayed reduced activity of the STS, insula and amygdala for complex vs basic emotions compared to controls. Moreover, the coupling between the STS and amygdala for complex vs basic emotions was reduced in the ASD group. Finally, groups differed with respect to the relationship between brain activity and behavioral performance. Brain activity during emotional prosody processing was more strongly related to prosody recognition accuracy in ASD participants. In contrast, the coupling between STS and anterior cingulate cortex (ACC) activity predicted behavioral task performance more strongly in the control group. These results provide evidence for aberrant emotional prosody processing of individuals with ASD. They suggest that the differences in the relationship between the neural and behavioral level of individuals with ASD may account for their observed deficits in social communication. PMID:27531389

To assess counseling to caregivers and classroom health education interventions to reduce environmental tobacco smoke exposure of children aged 5-6 years in China. In a randomized controlled trial in two preschools in Changsha, China, 65 children aged 5-6 years old and their smoker caregivers (65) were randomly assigned to intervention (n = 33) and control (no intervention) groups (n = 32). In the intervention group, caregivers received self-help materials and smoking cessation counseling from a trained counselor, while their children were given classroom-based participatory health education. Children's urinary cotinine level and the point prevalence of caregiver quitting were measured at baseline and after 6 months. At the 6-month follow-up, children's urinary cotinine was significantly lower (Z = -3.136; p = 0.002) and caregivers' 7-day quit rate was significantly higher (34.4% versus 0%) (p < 0.001; adjusted OR = 1.13; 95% CI: 1.02-1.26) in the intervention than control group. Helping caregivers quitting smoke combined with classroom-based health education was effective in reducing children's environmental tobacco smoke exposure. Larger-scale trials are warranted.

Abstract Backgrounds: The harvesting of great saphenous veins for coronary artery bypass graft (CABG) patients may result in significant complications, including lymphorrhagia, lymphoedema, incision infection, wound dehiscence, and skin flap necrosis. We investigated the function of a self-designed bilayered negative pressure wound therapy (b-NPWT) for reducing the above-mentioned complications using a clinical randomized controlled trial. Methods: A single-center, pilot randomized controlled trial was conducted. From December 2013 to March 2014, a total of 72 coronary heart disease patients (48 men and 24 women) received CABG therapy, with great saphenous veins were selected as grafts. Patients were equally randomized into a treatment and a control group. After the harvesting of the great saphenous veins and direct closure of the wound with sutures, b-NPWT was used for the thigh incision in the treatment group for 5 days (treatment thigh). Traditional surgical pads were applied to both the shank incisions of the treatment group patients (treatment shank) and the entire incisions of the control group (control thigh, control shank). Postoperative complications were recorded and statistically analyzed based on outcomes of thigh treatment, shank treatment, thigh control, and shank control groups. Results: The incidence rates of early complications, such as lymphorrhagia, lymphoedema, infection, wound dehiscence, and skin flap necrosis, of the vascular donor site in the thigh treatment group was significantly lower than those in the 3 other groups. Conclusions: The self-designed b-NPWT can effectively reduce postoperative complications, such as lymphedema, incision infection, wound dehiscence, and skin flap necrosis, in CABG patients who underwent great saphenous veins harvesting.

Autism is a neurodevelopmental disorder associated with social deficits and behavioral abnormalities. Recent evidence in autism suggests a deficit in glutathione (GSH), a major endogenous antioxidant. It is not known whether the synthesis, consumption, and/or regeneration of GSH is affected in autism. In the cerebellum tissues from autism (n=10) and age-matched control subjects (n=10), the activities of GSH-related enzymes glutathione peroxidase (GPx), glutathione-S-transferase (GST), glutathione reductase (GR), and glutamate cysteine ligase (GCL) involved in antioxidant defense, detoxification, GSH regeneration, and synthesis, respectively, were analyzed. GCL is a rate-limiting enzyme for GSH synthesis, and the relationship between its activity and the protein expression of its catalytic subunit GCLC and its modulatory subunit GCLM was also compared between the autistic and the control groups. Results showed that the activities of GPx and GST were significantly decreased in autism compared to that of the control group (P<0.05). Although there was no significant difference in GR activity between autism and control groups, 40% of autistic subjects showed lower GR activity than 95% confidence interval (CI) of the control group. GCL activity was also significantly reduced by 38.7% in the autistic group compared to the control group (P=0.023), and 8 of 10 autistic subjects had values below 95% CI of the control group. The ratio of protein levels of GCLC to GCLM in the autism group was significantly higher than that of the control group (P=0.022), and GCLM protein levels were reduced by 37.3% in the autistic group compared to the control group. A positive strong correlation was observed between GCL activity and protein levels of GCLM (r=0.887) and GCLC (r=0.799) subunits in control subjects but not in autistic subjects, suggesting that regulation of GCL activity is affected in autism. These results suggest that enzymes involved in GSH homeostasis have impaired activities in the cerebellum in autism, and lower GCL activity in autism may be related to decreased protein expression of GCLM.

To describe initiatives aiming to reduce the social gradient of smoking in the UK. A description of government initiatives to support smokers from low socioeconomic and other key groups, including National Health Service Stop Smoking Services and how they are seeking to support smokers to quit. The UK is employing a number of strategies to reduce smoking prevalence and is currently top of the Tobacco Control Scale in Europe but the health gap does not yet appear to be decreasing (in relation to smoking prevalence in deprived and higher income groups). More recently, efforts have been made to target smokers in more deprived groups to draw more of these smokers into the quitting process. While Stop Smoking Services are a key part of the UK's comprehensive tobacco control strategy and are reaching smokers from low socioeconomic groups, wider population strategies, such as ensuring all contacts with health-care professionals include advice to stop and the prohibition of remaining channels of tobacco marketing, are required to maximise the impact on deprived smokers. While smoking prevalence decreases among the general population are important, reducing smoking among disadvantaged groups is imperative to reduce health inequalities. It is too soon to say whether the new measures recently adopted in the UK will help to achieve this. © 2012 Australasian Professional Society on Alcohol and other Drugs.

Sodium intake is high in people with type 2 diabetes (T2DM). The aim of this study was to investigate whether urinary sodium excretion can be reduced by educating people with T2DM to read food labels and choose low sodium products. In a 3 month randomised controlled trial, 78 men (n=49) and women (n=29) with T2DM were recruited from a Diabetes Centre at a University teaching hospital. The intervention group was educated in a single session to use the nutrition information panel on food labels to choose products which complied with the Food Standards Australia New Zealand (FSANZ) guideline of <120 mg sodium/100 g food. The control group continued on their usual diet. The primary outcome measure was 24h urinary sodium excretion which was performed at baseline and 3 months. Data was analysed using repeated measures analysis of variance, independent samples t-test and Pearson's correlations. At 3 months mean urinary sodium excretion was unchanged in the intervention (174±13 mmol/24 h and 175±13 mmol/24 h) and control group (167±15mmol/24h and 161±13 mmol/24 h), and there was no between group difference (p>0.05). Sodium excretion was not reduced following the label reading education provided to this group of people with T2DM. Copyright © 2013 Elsevier Ltd. All rights reserved.

Purpose Endoscopic submucosal dissection (ESD) is a technically difficult and lengthy procedure requiring optimal depth of sedation. The bispectral index (BIS) monitor is a non-invasive tool that objectively evaluates the depth of sedation. The purpose of this prospective randomized controlled trial was to evaluate whether BIS guided sedation with propofol and remifentanil could reduce the number of patients requiring rescue propofol, and thus reduce the incidence of sedation- and/or procedure-related complications. Materials and Methods A total of 180 patients who underwent the ESD procedure for gastric adenoma or early gastric cancer were randomized to two groups. The control group (n=90) was monitored by the Modified Observer's Assessment of Alertness and Sedation scale and the BIS group (n=90) was monitored using BIS. The total doses of propofol and remifentanil, the need for rescue propofol, and the rates of complications were recorded. Results The number of patients who needed rescue propofol during the procedure was significantly higher in the control group than the BIS group (47.8% vs. 30.0%, p=0.014). There were no significant differences in the incidence of sedation- and/or procedure-related complications. Conclusion BIS-guided propofol infusion combined with remifentanil reduced the number of patients requiring rescue propofol in ESD procedures. However, this finding did not lead to clinical benefits and thus BIS monitoring is of limited use during anesthesiologist-directed sedation. PMID:25048506

We examined whether pretreatment with a small dose of thiopental was effective in reducing pain induced by the intravenous injection of rocuronium. Withdrawal movement was used to assess pain reduction. Ninety patients were randomly assigned to one of two groups: patients in the control group were pretreated with 2 mL saline, and those in the thiopental group were pretreated with 2 mL (50 mg) thiopental. Thiopental 5 mg/kg was injected intravenously. After a loss of consciousness, the upper arm was compressed with a rubber tourniquet, and the pretreatment drugs were administered. Thirty seconds later the tourniquet was removed and 0.6 mg/kg rocuronium was administered. Withdrawal movement was assessed using a four-grade scale: no movement, movement limited to the wrist, to the elbow or to the shoulder. The frequency of withdrawal movement in the group pretreated with thiopental was lower than in the control group (34 vs. 13, p < 0.05). We concluded that pretreatment with 2 mL (50 mg) thiopental is effective in reducing pain caused by the intravenous injection of rocuronium. PMID:16385651

Following the high rate of consumption of Cola nitida (cola nut) among the male population in Nigeria, this study seeks to determine the effects of consumption of Cola nitida on serum reproductive hormones and sperm count, which are major determinants of male fertility. Thirty-two male albino wistar rats weighing 180-220 g were used for this study and were divided into 4 groups of eight animals each. Group 1 served as control, group 2 received 2 mg/kg Cola nitida extract (Test 1), group 3 received 6 mg/kg Cola nitida extract (Test 2) and group 4 received 10 mg/kg Cola nitida extract (Test 3). After 6 weeks of treatment, reproductive hormonal assay was carried out using the rat serum. Epididymal spermatozoa were collected and sperm count determined. Serum concentrations of luteinizing hormone (LH) and testosterone were significantly (P < 0.05) reduced in test 2 and 3, compared with control. Sperm count was significantly lower in test group 1 (P < 0.05), 2 (P < 0.001) and 3 (P < 0.001) compared with control, with test 3 significantly (P < 0.05) lower compared with test 1. There was no significant difference in testicular and epididymis weight in the different experimental groups studied. Aqueous seed extract of Cola nitida rubra resulted in reduced serum reproductive hormone concentrations and sperm count in male wistar rats, and may therefore be detrimental to reproductive health, hence the need for regulation of its consumption.

AIM: To investigate the preventive effect of kefir on colitis induced with dextran sulfate sodium (DSS) in rats. METHODS: Twenty-four male Wistar-albino rats were randomized into four groups: normal control, kefir-control, colitis, and kefir-colitis groups. Rats in the normal and kefir-control groups were administered tap water as drinking water for 14 d. Rats in the colitis and kefir-colitis groups were administered a 3% DSS solution as drinking water for 8-14 d to induce colitis. Rats in the kefir-control and kefir-colitis groups were administered 5 mL kefir once a day for 14 d while rats in the normal control and colitis group were administered an identical volume of the placebo (skim milk) using an orogastric feeding tube. Clinical colitis was evaluated with reference to the disease activity index (DAI), based on daily weight loss, stool consistency, and presence of bleeding in feces. Rats were sacrificed on the 15th day, blood specimens were collected, and colon tissues were rapidly removed. Levels of myeloperoxidase (MPO), tumor necrosis factor (TNF)-α, interleukin (IL)-10, malondialdehyde, and inducible nitric oxide synthase (iNOS) were measured in colon tissue. RESULTS: The DAI was lower in the kefir-colitis group than in the colitis group (on the 3rd and 5th days of colitis induction; P < 0.01). The DAI was also significantly higher in the colitis group between days 2 and 6 of colitis induction when compared to the normal control and kefir-control groups. The DAI was statistically higher only on the 6th day in the kefir-colitis group when compared to that in the normal control groups. Increased colon weight and decreased colon length were observed in colitis-induced rats. Mean colon length in the colitis group was significantly shorter than that of the kefir-control group. Kefir treatment significantly decreased histologic colitis scores (P < 0.05). MPO activity in the colitis group was significantly higher than in the kefir-control group (P < 0.05). Kefir treatment significantly reduced the DSS colitis-induced TNF-α increase (P < 0.01). No statistically significant differences were observed among groups for IL-10 and MDA levels. Colon tissue iNOS levels in the colitis group were significantly higher than those in the control and kefir-colitis groups (P < 0.05). CONCLUSION: Kefir reduces the clinical DAI and histologic colitis scores in a DSS-induced colitis model, possibly via reduction of MPO, TNF-α, and iNOS levels. PMID:26676086

To investigate the treatment and mechanism of compound carraghenates suppository to rat acute rectal mucous injury. The model of rat acute rectal mucous injury was established by 3% acetic acid. Two hundred and forty rats were divided equally into control and experimental group. The rats of experimental group were administrated with 20 mg carraghenates suppository via rectum twice a day, but rats of control group were not administrated with carraghenates suppository. Thirty rats in both groups were executed at different time points. The pathologic changes were observed and the rectal mucous injury was scored. Immunohistochemical staining was used to evaluate the effect of carraghenates suppository on expression of VEGF, iNOS, IL-8, MMP9, HIF-1 alpha and PCNA in the two groups. The scores of rectal mucous injury was lower, the pathologic changes such as hyperaemia, edema, destroy of glands were less severe, and tissue repair time was shorter in experimental group compared with those in the control group at 24 h, 78 h and 120 h after administration of carraghenates suppository. No obvious cicatrisation was observed in experimental group. Expression of VEGF and MMP9 was significantly lower in experimental group compared with those in the control group at 24 h after administration. Expression of VEGF, iNOS, IL-8, MMP9, HIF-1alpha and PCNA were statistically decreased in experimental group than those in the control group at 72 h, 120 h after administration. MVD in experimental group was statistically decreased than that in the control group. The compound carraghenates suppository can reduce the rectal mucous injury from 3% acetic acid, and accelerate the wound healing without obvious cicatrisation. The compound carraghenates suppository can reduce the expression of MMP9, VEGF, IL-8, PCNA, iNOS and HIF-1 alpha, which may play a role in its protective mechanism.

Caloric restriction (CR) is the only treatment known to substantially prolong both average and maximal life span in experimental animals. Interventions that mimic certain effects of CR could be potential anti-aging treatments in humans. Drugs which reduce appetite (anorexiants) represent one class of candidate treatments. Agents that reduce the glucose utilization by the organism could also represent another class of candidate CR mimetics. In our study, we addressed the following questions: (1) Does treatment with an anorexiant reduce caloric intake and body weight of experimental animals comparable to that caused by CR? (2) Does treatment with an antidiabetic agent influence caloric intake and body weight? (3) Does treatment with any of these drugs affect metabolic parameters of an organism in the way similar to that observed with CR? One hundred and twenty 6-month-old female Wistar-derived LIO rats were randomly subdivided into four groups and exposed to: (1) ad libitum feeding with placebo (controls); (2) the antidiabetic drug phenformin (2 mg/kg); (3) the anorectic drug phentermine (1 mg/kg), and (4) the same amount of food as the group with the least food intake during the previous week (pair-fed controls). Food and water intake, body weight, and rectal temperature were measured weekly during 16 weeks. At the end of the 16th week of the experiment, serum levels of glucose, total beta-lipoprotein and pre-beta-lipoprotein fractions, cholesterol, triglycerides, insulin, total triiodothyronine, and free thyroxine were estimated. The contents of diene conjugates and Schiff's bases, total antioxidant activity, the activities of Cu/Zn superoxide dismutase, glutathione S-transferase, and glutathione peroxidase, and the generation of reactive oxygen species (ROS) were studied in brain and liver homogenates and in the serum. The controls exposed to pair feeding had a significantly reduced food consumption (about 20%) as compared with the ad libitum fed controls and thus exhibited a moderate CR. Treatment with phentermine reduced the caloric intake by about 12% as compared with the ad libitum fed controls. Body weight and water intake in this group were only slightly decreased (by about 2 and 5%, respectively) as compared with the controls. The mean rectal temperature in the phentermine group (38 degrees C) was significantly higher than in the ad libitum fed (37.8 degrees C) and pair-fed (37.6 degrees C) controls. Treatment with phentermine also resulted in significantly reduced ROS levels in all tissues studied, while the highest ROS production was found in ad libitum (blood serum) and pair-fed (brain) controls. Treatment with phenformin did not significantly influence food and water consumption, body weight, and temperature when compared with the ad libitum fed controls. Rats treated with this antidiabetic drug showed intermediate values of ROS generation. Differences among the groups in total antioxidant activity were not obvious. Treatment with phentermine reduces caloric intake slightly less than is commonly observed in CR studies. CR due to forcibly reduced feeding and CR due to substance-suppressed appetite appear to act through different metabolic mechanisms and thus may affect aging and longevity in different ways.

Our study aimed at determining the effect of stachydrine on the PERK, CHOP, and caspase-3 in rat kidney with RIF. Rats were randomly divided into control group, model group, enalapril group, high stachydrine group, medium stachydrine group, and low stachydrine group. RIF models of five groups were developed by unilateral ureteral obstruction except the control group. The rats were sacrificed 12 days after surgery and blood samples were collected. Serum creatinine (Scr) and blood urea nitrogen (BUN) levels were detected. Renal tubular damage index was determined by HE staining. The area percentage of RIF was determined by the Masson method. Expressions of PERK, CHOP, and caspase-3 in kidney were determined by immunohistochemistry. Tubulointerstitial injury index, RIF, serum Scr, BUN level, and expressions of PERK, CHOP, and caspase-3 were different between the model and treatment groups (P < 0.05; P < 0.01). The expressions of PERK, CHOP, and caspase-3 in nephridial tissue were reduced (P < 0.05), tubulointerstitial injury and RIF were reduced (P < 0.05), and Scr and BUN were lower (P < 0.05) in the high stachydrine group than those in the enalapril group. The expressions of PERK, CHOP, and caspase-3 were reduced in the endoplasmic reticulum stress-related apoptosis pathway after stachydrine treatment. Consequently, apoptosis was prevented, and RIF was inhibited.

Data are limited on the efficacy of health-focused interventions for young, low-acculturated Latino women. Because breast cancer is the most commonly diagnosed cancer and the most common cause of cancer mortality in this population, combined interventions that address both early detection and dietary patterns could help reduce both morbidity and mortality associated with breast cancer in this underserved population. Mujeres Felices por ser Saludables was randomized intervention study designed to assess the efficacy of an 8-month combined dietary and breast health intervention to reduce fat and increase fiber intake as well as to increase the frequency and proficiency of breast self-examination (BSE) and reduce anxiety related to BSE among Latinas. Blocked randomization in blocks of 6 was used to randomize 256 20- to 40-year-old Latinas to the intervention (n = 127) or control group (n = 129). The intervention group attended an 8-month multicomponent education program designed specifically for low-acculturated Latinas. The control group received mailed health education material on a schedule comparable to the intervention. A total of 195 women (76.2%) completed both the baseline and 8-month follow-up interviews. The intervention and control groups were similar on baseline sociodemographic characteristics. At the 8-month follow up, the intervention group reported lower dietary fat (P < .001) and higher fiber intake (p = .06); a higher proportion reported practicing BSE at the recommended interval (p < .001) and showed improved BSE proficiency (p < .001) compared to the control group. BSE-related anxiety was low for both groups at baseline, and no difference in reduction was observed. This project provides a successful model for achieving dietary change and improving breast health behavior in young, low-acculturated Latinas.

Purpose: To analyze the effect of reduced-dose radiotherapy on local control in children with low-risk rhabdomyosarcoma (RMS) treated in the Children's Oncology Group D9602 study. Methods and Materials: Patients with low-risk RMS were nonrandomly assigned to receive radiotherapy doses dependent on the completeness of surgical resection of the primary tumor (clinical group) and the presence of involved regional lymph nodes. After resection, most patients with microscopic residual and uninvolved nodes received 36 Gy, those with involved nodes received 41.4 to 50.4 Gy, and those with orbital primary tumors received 45 Gy. All patients received vincristine and dactinomycin, with cyclophosphamide addedmore » for patient subsets with a higher risk of relapse in Intergroup Rhabdomyosarcoma Study Group III and IV studies. Results: Three hundred forty-two patients were eligible for analysis; 172 received radiotherapy as part of their treatment. The cumulative incidence of local/regional failure was 15% in patients with microscopic involved margins when cyclophosphamide was not part of the treatment regimen and 0% when cyclophosphamide was included. The cumulative incidence of local/regional failure was 14% in patients with orbital tumors. Protocol-specified omission of radiotherapy in girls with Group IIA vaginal tumors (n = 5) resulted in three failures for this group. Conclusions: In comparison with Intergroup Rhabdomyosarcoma Study Group III and IV results, reduced-dose radiotherapy does not compromise local control for patients with microscopic tumor after surgical resection or with orbital primary tumors when cyclophosphamide is added to the treatment program. Girls with unresected nonbladder genitourinary tumors require radiotherapy for postsurgical residual tumor for optimal local control to be achieved.« less

Cognitive deficits are common in depression and may persist following the resolution of affective symptoms. However, therapeutic strategies that successfully target cognitive impairments are lacking. Recent work has demonstrated that playing action video games leads to improvements in cognition, in particular executive function, in healthy individuals. We therefore set out to test whether playing video games can reduce symptoms associated with depression. We focussed on depressive symptoms and on rumination, since rumination is a good predictor of depression and may contribute to triggering depression. We recruited 68 clinically depressed individuals (mean age: 46 years, 47 females) that were randomized into the training group playing a fast paced action video game for 6 weeks or a waitlist control group. Before and after training participants completed online questionnaires and a neuropsychological test battery. Only participants who actually played the game were included in the analysis. The final sample consisted of n = 21 training group and n = 29 waitlist control group. The training group showed significantly higher subjective cognitive ability, as well as lower self-reported rumination at posttest in contrast to the control group (although these findings do not survive Bonferroni correction). On a subsample with cognitive performance data (n = 19) we detected an improvement in executive function (Trail Making Task A and B) in the training compared with the control group. The results show that the fast paced action video game employed in the present study improved Trail Making performance and may reduce rumination and enhance subjective cognitive ability. Future research may focus on the investigation of the precise cognitive profile of effects. PMID:29483888

Low level laser therapy (LLLT) has been suggested as an effective therapeutics in inflammatory processes modulation and tissue repairing. However, there is a lack of studies that analyze the anti-inflammatory effects of the infrared lasers in muscular skeletal injury. The aim of this study was to investigate the effects of low-level laser therapy 904 nm in the repair process of skeletal muscle tissue. Swiss mice were submitted to cryoinjury and divided in test (LLLT-treated) and control groups. Histological sections were stained with hematoxylin-eosin to assess general morphology and inflammatory influx, and Picrossirus to quantify collagen fibers deposition. Our results showed significant reduction in inflammatory infiltrated in irradiated mice after 4 days of treatment compared to control ( p = 0.01). After 8 days, the irradiated group showed high levels at regenerating myofibers with significant statistically differences in relation at control group ( p < 0.01). Collagen deposition was significantly increased in the final stages of regeneration at test group, when compared with control group ( p = 0.05). Our data suggests that LLLT reduces the inflammatory response in the initial stages of injury and accelerates the process of muscular tissue repair.

Preliminary studies in rats (COSMOS 1887) suggested that levels of posterior pituitary hormones were reduced by exposure to spaceflight. To confirm these preliminary findings, pituitary tissue from rats flown for 14 days on Cosmos 2044 is obtained. Posterior pituitary content of oxytocin (OT) and vasopressin (VP) were measured in these tissues as well as those from ground-based controls. The synchronous control group had feeding and lighting schedules synchronized to those in the spacecraft and were maintained in flight-type cages. Another group was housed in vivarium cages; a third group was tail suspended (T), a method used to simulate microgravity. Flight rats showed an average reduction of 27 in pituitary OT and VP compared with the three control groups. When hormone content was expressed in terms of pituitary protein (microg hormone/mg protein), the average decrease in OT and VP for the flight animals ranged from 20 to 33 percent compared with the various control groups. Reduced levels of pituitary OT and VP were similar to preliminary measurements from the Cosmos 1887 mission and appear to result from exposure to spaceflight. These data suggest that changes in the rate of hormone secretion or synthesis may have occurred during exposure to microgravity.

This study aims to study the effect of Rho kinase inhibitor fasudil on the expression endothelin-1 (ET-1) and nitric oxide (NO) in rats with hypoxic pulmonary hypertension (HPH). Twenty-four male SD rats were randomly divided into three groups: control group, model group (HPH group) and HPH+fasudil group. The rat HPH model was established by intermittent hypoxia (IH) at atmospheric pressure. Mean pulmonary artery pressure (mPAP), right ventricular hypertrophy index (RVHI), ET-1 and NO levels, and pulmonary vascular structural changes were observed in all groups. MPAP, RVHI and ET-1 levels were significantly higher in HPH group than in control group, while NO was significantly lower than in control group. In addition, mPAP, RVHI and ET-1 were significantly lower in the HPH+fasudil group than in the HPH group. In the HPH group, ET-1 level was significantly and positively correlated with mPAP and RVHI, NO was negatively correlated with mPAP and RVHI levels, and ET-1 level was significantly and negatively correlated with NO level. In the HPH group, pulmonary arteriolar walls were generally thickened, and lumen stenosis was obvious; while after fasudil treatment, pulmonary arteriolar wall thickening and stenosis degree were significantly reduced. Fasudil can significantly reduce ET-l level and increase NO level in HPH rats, suppressing the development of pulmonary arterial hypertension.

Objective To determine if a school based educational programme aimed at reducing consumption of carbonated drinks can prevent excessive weight gain in children. Design Cluster randomised controlled trial. Setting Six primary schools in southwest England. Participants 644 children aged 7-11 years. Intervention Focused educational programme on nutrition over one school year. Main outcome measures Drink consumption and number of overweight and obese children. Results Consumption of carbonated drinks over three days decreased by 0.6 glasses (average glass size 250 ml) in the intervention group but increased by 0.2 glasses in the control group (mean difference 0.7, 95% confidence interval 0.1 to 1.3). At 12 months the percentage of overweight and obese children increased in the control group by 7.5%, compared with a decrease in the intervention group of 0.2% (mean difference 7.7%, 2.2% to 13.1%). Conclusion A targeted, school based education programme produced a modest reduction in the number of carbonated drinks consumed, which was associated with a reduction in the number of overweight and obese children.

Notwithstanding a high expectation for internet-based cognitive behavioral therapy (iCBT) for reducing depressive symptoms, many of iCBT programs have limitations such as temporary effects and high drop-out rates, possibly due to their complexity. We examined the effects of a free, simplified, 5-minute iCBT program by comparing it with a simplified emotion-focused mindfulness (sEFM) exercise and with a waiting list control group. A total of 974 participants, who were recruited using the website of a market research company, were randomly assigned to the iCBT group, the sEFM group, and the control group. Those in the intervention arms performed each exercise for 5 weeks. The primary outcome measure was the Center for Epidemiological Studies Depression scale (CES-D) at postintervention. Secondary outcome measures were the Patient Health Questionnaire-9 (PHQ-9) and the Generalized Anxiety Disorder-7 scale (GAD-7). Intention-to-treat analyses were conducted. During postintervention assessment, there were no significant differences between the intervention arms and the control group in the CES-D, although the difference between the iCBT arm and control group was close to significance (p = 0.05) in favor of iCBT. There was a significant difference in the PHQ-9 in favor of the sEFM group compared with the control group. There were no significant differences in outcome measures between the three groups at the 6-week follow-up. Although both iCBT and sEFM have the potential to temporarily reduce depressive symptoms, substantial improvements are required to enhance and maintain their effects. This trial is registered with the UMIN Clinical Trial Registry (UMIN-CTR) (ID: UMIN000015097 ) on 1 October 2014.

A new reduced-dose tetanus-diphtheria (Td) vaccine was developed in Korea, and phase I and II clinical trials were successfully undertaken. We conducted this double-blind, randomized, multicenter phase III clinical trial to assess the immunogenicity and safety of the new Td vaccine. Healthy adolescents 11-12 years of age were enrolled and randomized to receive the new Td vaccine (study group) or a commercially available Td vaccine (control group). Blood samples were collected prior to and 4 weeks after the vaccination. Between the study and control groups, seroprotection rate, booster response, and geometric mean titer of antibodies against diphtheria and tetanus toxoids were compared after the vaccination. All solicited and unsolicited adverse events and serious adverse events during the 6-week study period were monitored. A total of 164 adolescents received vaccination, and 156 of them were evaluated to assess immunogenicity. The seroprotection rate and geometric mean titer for antibodies against diphtheria were significantly higher in the study group, whereas those against tetanus were significantly higher in the control group. However, all seroprotection rates against diphtheria and tetanus in the study and control groups were high: 100% against diphtheria and tetanus in the study group, and 98.7% against diphtheria and 100% against tetanus in the control group. No significant differences in the frequency of solicited and unsolicited adverse events were observed between the two vaccine groups. The new Td vaccine is highly immunogenic and safe, and this new Td vaccine can be effectively used for preventing diphtheria and tetanus. Copyright © 2015. Published by Elsevier B.V.

Gut hormones play an important role in the adaptation of the immature neonatal gut, and their secretion may be modulated by prebiotics. Furthermore, prebiotics are well known for their hypolipidemic potentials. We tested the hypothesis that prebiotics could alter motilin and gastrin secretion and reduce lipids in healthy preterms. A total of 167 newborns were randomized to either a prebiotics enriched formula containing dietary oligosaccharides (short-chain galacto-oligo-saccharides/long-chain fructo-oligo-saccharides [scGOS/lcFOS]), at a concentration of 0.8 g/100 ml, or a common preterm formula. Day 1 and 16 basal motilin, gastrin concentrations, and lipids were evaluated together with growth parameters, gastric residue, bowel habits, and feeding tolerance. Adverse events including necrotizing enterocolitis (NEC) and septicemia were also recorded. Mean motilin increase and day 16 mean values were greater for the intervention, compared with the control group (P = .001, P = .005, respectively), while gastrin remained high in both groups. Mean cholesterol and low density lipoprotein (LDL) increase were significantly greater in the control, compared with the intervention (P = .037, and P = .001) group. Day 16 LDL levels were significantly higher in the control group. Mean weight was increased in the control group, while gastric residue was less and stool frequency was increased in the intervention group. NEC and septicemia were not statistically different between groups. A prebiotics enriched formula resulted in significant surge of motilin relating to reduced gastric residue, compared with a common preterm formula. Mean cholesterol change was lower, while LDL was not increased in the prebiotics group, compared with the control group. © 2013 American Society for Parenteral and Enteral Nutrition.

We investigated the immune camouflage effects of methoxy polyethylene glycol succinimidyl propionate (mPEG-SPA) on corneal antigens and explored a novel approach for reducing corneal antigenicity, thereby decreasing corneal graft rejection. Importantly, this approach did not alter normal local immunity. Corneal grafts were treated with mPEG-SPA 5KD or 20KD (3% W/V), which could shield major histocompatibility antigen class I molecules (RT1-A) of corneal grafts. Skin grafts of Wistar rats were transplanted to SD rats. Then the splenic lymphocytes were isolated from SD rats. Subsequently, the lymphocytes were co-cultured with autologous corneal grafts or untreated corneal grafts and PEGylated grafts treated with mPEG-SPA 5KD or 20KD obtained from the counterpart skin donors, which were used as autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group, respectively. Lymphocyte proliferation was lower in mPEG-SPA 5KD group and mPEG-SPA 20KD group than in the allogeneic control. SD rats with corneal neovascularisation were used as recipients for high-risk corneal transplantation and were randomly divided into four groups: autologous control, allogeneic control, mPEG-SPA 5KD group and mPEG-SPA 20KD group. The recipients received corneal grafts from Wistar rats. Corneal graft survival was prolonged and graft rejection was reduced in the mPEG-SPA 5KD group and the mPEG-SPA 20KD group compared to the allogeneic control. Thus, we think that mPEG-SPA could immunologically camouflage corneal antigens to prolong corneal grafts survival in high-risk transplantation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Musculoskeletal injuries among health care workers is very high, particularly so in direct care workers involved in patient handling. Efforts to reduce injuries have shown mixed results, and strong evidence for intervention effectiveness is lacking. The purpose of our study was to evaluate the effectiveness of a Transfer, Lifting and Repositioning (TLR) program to reduce musculoskeletal injuries (MSI) among direct health care workers. This study was a pre- and post-intervention design, utilizing a nonrandomized control group. Data were collected from the intervention group (3 hospitals; 411 injury cases) and the control group (3 hospitals; 355 injury cases) for periods 1 year pre- and post-intervention. Poisson regression analyses were performed. Of a total 766 TLR injury cases, the majority of injured workers were nurses, mainly with back, neck, and shoulder body parts injured. Analysis of all injuries and time-loss rates (number of injuries/100 full-time employees), rate ratios, and rate differences showed significant differences between the intervention and control groups. All-injuries rates for the intervention group dropped from 14.7 pre-intervention to 8.1 post-intervention. The control group dropped from 9.3 to 8.4. Time-loss injury rates decreased from 5.3 to 2.5 in the intervention group and increased in the control group (5.9 to 6.5). Controlling for group and hospital size, the relative rate of all-injuries and time-loss injuries for the pre- to post-period decreased by 30% (RR = 0.693; 95% CI = 0.60-0.80) and 18.6% (RR = 0.814; 95% CI = 0.677-0.955), respectively. The study provides evidence for the effectiveness of a multifactor TLR program for direct care health workers, especially in small hospitals.

Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P < 0.00001) compared with the control groups. Group II demonstrated a significant difference in vaginal bleeding time (P < 0.00001), the amount of vaginal bleeding (P = 0.0002), menstruation recovery period (P < 0.00001), and endometrial thickness at 2 (P = 0.003) and 3 (P < 0.00001) weeks postabortion compared with the control group. Similarly, a significant difference was observed in group III for reducing vaginal bleeding time (P < 0.00001) and the amount of vaginal bleeding (P < 0.00001), shortening the menstruation recovery period (P < 0.00001), and increasing endometrial thickness 2 and 3 weeks after surgical abortion (P < 0.00001, all). Immediate administration of OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies.

The occurrence of seroma formation after axillary lymphadenectomy for breast cancer cannot be ignored. Various approaches have been used in an effort to reduce it, but these results are still controversial. We aimed to describe a new method of application of OK-432 (Sapylin, heat-treated Su strain of Streptococcus) to reduce seroma formation after axillary lymphadenectomy for breast cancer and to verify the safety and efficacy of it as a beneficial supplement for conventional surgery. A prospective, randomized analysis of consecutive quadrantectomy or mastectomy plus axillary lymphadenectomy using or not using OK-432 was designed. From July 2010 to November 2011, a total of 111 patients were enrolled in this prospective, randomized study and completed the follow-up. OK-432 applied to the axillary fossa plus placement of closed suction drainage was used in 54 patients (the experimental group); placement of closed suction drainage was used in 57 patients (the control group). There were no statistical significance between the two groups in terms of age, body mass index, treatment received, tumor size, number of removed lymph nodes, and lymph node status. Postoperative drainage magnitude and duration were significantly reduced in the experimental group (P = 0.008 and 0.003, respectively). One week after hospital discharge, fewer patients developed a palpable seroma in the experimental group: 10 in the experimental group versus 28 in the control group (P = 0.001). Fewer seromas needed aspiration (mean 1 [range 0-3] in the experimental group vs. mean 4 [range 1-5] in the control group; P < 0.001). There were no significant differences in terms of the incidence of complications associated with axillary lymphadenectomy (P = 0.941). OK-432 is a feasible and safe option for axillary lymphadenectomy for breast cancer. The use of it does not always prevent seroma formation, but it can reduce drainage magnitude and duration, as well as decrease the incidence of seroma after the removal of drainage. It may be increasingly conducted in day surgery clinics.

This pilot study was designed to utilize stroke volume variation and cardiac index to ensure fluid optimization during one-lung ventilation in patients undergoing thoracoscopic lobectomies. Eighty patients undergoing thoracoscopic lobectomy were randomized into either a goal-directed therapy group or a control group. In the goal-directed therapy group, the stroke volume variation was controlled at 10%±1%, and the cardiac index was controlled at a minimum of 2.5 L.min-1.m-2. In the control group, the MAP was maintained at between 65 mm Hg and 90 mm Hg, heart rate was maintained at between 60 BPM and 100 BPM, and urinary output was greater than 0.5 mL/kg-1/h-1. The hemodynamic variables, arterial blood gas analyses, total administered fluid volume and side effects were recorded. The PaO2/FiO2-ratio before the end of one-lung ventilation in the goal-directed therapy group was significantly higher than that of the control group, but there were no differences between the goal-directed therapy group and the control group for the PaO2/FiO2-ratio or other arterial blood gas analysis indices prior to anesthesia. The extubation time was significantly earlier in the goal-directed therapy group, but there was no difference in the length of hospital stay. Patients in the control group had greater urine volumes, and they were given greater colloid and overall fluid volumes. Nausea and vomiting were significantly reduced in the goal-directed therapy group. The results of this study demonstrated that an optimization protocol, based on stroke volume variation and cardiac index obtained with a FloTrac/Vigileo device, increased the PaO2/FiO2-ratio and reduced the overall fluid volume, intubation time and postoperative complications (nausea and vomiting) in thoracic surgery patients requiring one-lung ventilation.

Local cancer relapse risk after breast conservation surgery followed by radiotherapy has fallen sharply in many countries, and is influenced by patient age and clinicopathological factors. We hypothesise that partial-breast radiotherapy restricted to the vicinity of the original tumour in women at lower than average risk of local relapse will improve the balance of beneficial versus adverse effects compared with whole-breast radiotherapy. IMPORT LOW is a multicentre, randomised, controlled, phase 3, non-inferiority trial done in 30 radiotherapy centres in the UK. Women aged 50 years or older who had undergone breast-conserving surgery for unifocal invasive ductal adenocarcinoma of grade 1-3, with a tumour size of 3 cm or less (pT1-2), none to three positive axillary nodes (pN0-1), and minimum microscopic margins of non-cancerous tissue of 2 mm or more, were recruited. Patients were randomly assigned (1:1:1) to receive 40 Gy whole-breast radiotherapy (control), 36 Gy whole-breast radiotherapy and 40 Gy to the partial breast (reduced-dose group), or 40 Gy to the partial breast only (partial-breast group) in 15 daily treatment fractions. Computer-generated random permuted blocks (mixed sizes of six and nine) were used to assign patients to groups, stratifying patients by radiotherapy treatment centre. Patients and clinicians were not masked to treatment allocation. Field-in-field intensity-modulated radiotherapy was delivered using standard tangential beams that were simply reduced in length for the partial-breast group. The primary endpoint was ipsilateral local relapse (80% power to exclude a 2·5% increase [non-inferiority margin] at 5 years for each experimental group; non-inferiority was shown if the upper limit of the two-sided 95% CI for the local relapse hazard ratio [HR] was less than 2·03), analysed by intention to treat. Safety analyses were done in all patients for whom data was available (ie, a modified intention-to-treat population). This study is registered in the ISRCTN registry, number ISRCTN12852634. Between May 3, 2007, and Oct 5, 2010, 2018 women were recruited. Two women withdrew consent for use of their data in the analysis. 674 patients were analysed in the whole-breast radiotherapy (control) group, 673 in the reduced-dose group, and 669 in the partial-breast group. Median follow-up was 72·2 months (IQR 61·7-83·2), and 5-year estimates of local relapse cumulative incidence were 1·1% (95% CI 0·5-2·3) of patients in the control group, 0·2% (0·02-1·2) in the reduced-dose group, and 0·5% (0·2-1·4) in the partial-breast group. Estimated 5-year absolute differences in local relapse compared with the control group were -0·73% (-0·99 to 0·22) for the reduced-dose and -0·38% (-0·84 to 0·90) for the partial-breast groups. Non-inferiority can be claimed for both reduced-dose and partial-breast radiotherapy, and was confirmed by the test against the critical HR being more than 2·03 (p=0·003 for the reduced-dose group and p=0·016 for the partial-breast group, compared with the whole-breast radiotherapy group). Photographic, patient, and clinical assessments recorded similar adverse effects after reduced-dose or partial-breast radiotherapy, including two patient domains achieving statistically significantly lower adverse effects (change in breast appearance [p=0·007 for partial-breast] and breast harder or firmer [p=0·002 for reduced-dose and p<0·0001 for partial-breast]) compared with whole-breast radiotherapy. We showed non-inferiority of partial-breast and reduced-dose radiotherapy compared with the standard whole-breast radiotherapy in terms of local relapse in a cohort of patients with early breast cancer, and equivalent or fewer late normal-tissue adverse effects were seen. This simple radiotherapy technique is implementable in radiotherapy centres worldwide. Cancer Research UK. Copyright © 2017 The Author(s). Published by Elsevier Ltd.

Ineffective evacuation of intrathoracic fluid after cardiac surgery (retained blood syndrome [RBS]) might increase postoperative complications, morbidity, and mortality. Active tube clearance (ATC) technology using an intraluminal clearing apparatus aims at increasing chest tube drainage efficiency. This study evaluated whether ATC reduces RBS in an all-comers collective undergoing scheduled cardiac surgery with cardiopulmonary bypass and full or partial median sternotomy. In this nonrandomized prospective trial, 581 consecutive patients undergoing scheduled cardiac surgery with median sternotomy between January 2016 and December 2016 were assigned to receive conventional chest tubes (control group) or a combination of conventional tubes and as many as two ATC devices (ATC group), depending on their operation date. Postoperative occurrence of RBS (one or more of the following: reexploration for bleeding or tamponade, pericardial drainage procedure, pleural drainage procedure) and other endpoints were compared. Propensity score matching was applied. In 222 ATC patients and 222 matched control patients, RBS occurrence did not differ between the groups (ATC 16%, control 22%; p = 0.15). However, reexploration rate for bleeding or tamponade was significantly reduced in the ATC group compared with the control group (4.1% versus 9.1%, respectively; p = 0.015). The mortality of RBS patients (21%) was higher compared with patients without RBS (3.9%, p < 0.001). Among the RBS components, only reexploration (odds ratio 16, 95% confidence interval: 5.8 to 43, p < 0.001) was relevant for inhospital mortality (ATC 6.8%, control 7.7%; p = 0.71). Active tube clearance is associated with reduced reexploration rates in an all-comers collective undergoing cardiac surgery. Reexploration is the only RBS component relevant for mortality. The ATC effect does not translate into improved overall survival. Copyright © 2018 The Society of Thoracic Surgeons. Published by Elsevier Inc. All rights reserved.

The purpose of the study was to investigate the effects of a 12-week yoga program on heart rate variability (HRV) and depressive symptoms in depressed women. This was a randomized controlled trial. Twenty-six sedentary women scoring ≥14 on the Beck Depression Inventory-II were randomized to either the yoga or the control group. The yoga group completed a 12-week yoga program, which took place twice a week for 60 min per session and consisted of breathing exercises, yoga pose practice, and supine meditation/relaxation. The control group was instructed not to engage in any yoga practice and to maintain their usual level of physical activity during the course of the study. Participants' HRV, depressive symptoms, and perceived stress were assessed at baseline and post-test. The yoga group had a significant increase in high-frequency HRV and decreases in low-frequency HRV and low frequency/high frequency ratio after the intervention. The yoga group also reported significantly reduced depressive symptoms and perceived stress. No change was found in the control group. A 12-week yoga program was effective in increasing parasympathetic tone and reducing depressive symptoms and perceived stress in women with elevated depressive symptoms. Regular yoga practice may be recommended for women to cope with their depressive symptoms and stress and to improve their HRV.

Under experimental clinical conditions diet modification has been shown to reduce serum cholesterol levels. This paper reports such a positive response to a nonpharmacologic, behavioral education program at the worksite. Employees at the New York Telephone Company corporate headquarters were assigned randomly to treatment and control groups. Treatment consisted of an 8-week group cholesterol reduction program conducted during employee lunch hours. It comprised a multiple-treatment approach--food behavior change techniques combined with nutrition education, physical activity planning, and self-management skills. The treatment group showed substantial change compared with the control group at the program's completion. Those treated displayed a significant 6.4% reduction in total serum cholesterol (266 mg% average at baseline) as compared with control subjects with a corresponding decrease in high-density lipoprotein levels. A significant increase in nutrition knowledge and moderate weight loss were also documented for this group. The magnitudes of a participant's baseline serum cholesterol level and his/her reduction in percentage of ideal body weight were positively and independently correlated with percentage changes in serum cholesterol levels. Over the same period, decreases in high-density lipoprotein levels and no changes in serum cholesterol, weight, and nutrition knowledge were observed for the control group. Overall, participants in the treatment program successfully reduced the coronary heart disease risk factors of elevated cholesterol and weight. Directions for future study are suggested.

To identify the immediate and middle-term effects of the right carotid sinus compression technique on blood pressure and heart rate in hypertensive patients. Randomized blinded experimental study. Primary health centers of Cáceres (Spain). Sixty-four medicated patients with hypertension were randomly assigned to an intervention group (n = 33) or to a control group (n = 31). In the intervention group a compression of the right carotid sinus was applied for 20 sec. In the control group, a placebo technique of placing hands on the radial styloid processes was performed. Blood pressure and heart rate were measured in both groups before the intervention (preintervention), immediately after the intervention, 5 min after the intervention, and 60 min after the intervention. The intervention group significantly decreased systolic and diastolic blood pressure and heart rate immediately after the intervention, with a large clinical effect; systolic blood pressure remained reduced 5 min after the intervention, and heart rate remained reduced 60 min after the intervention. No significant changes were observed in the control group. Right carotid sinus compression could be clinically useful for regulating acute hypertension.

Eighty-four prenatally depressed women were randomly assigned to yoga, massage therapy or standard prenatal care control groups to determine the relative effects of yoga and massage therapy on prenatal depression and neonatal outcomes. Following 12 weeks of twice weekly yoga or massage therapy sessions (20 min each) both therapy groups versus the control group had a greater decrease on depression, anxiety and back and leg pain scales and a greater increase on a relationship scale. In addition, the yoga and massage therapy groups did not differ on neonatal outcomes including gestational age and birthweight, and those groups, in turn, had greater gestational age and birthweight than the control group.

Polyphenol-rich grape seeds have a beneficial effect on human health. The present study was performed to investigate the effects of grape seeds on antioxidant activities in rats. Male Sprague-Dawley rats were randomly divided into a control diet group (C), a high-fat diet group (HF), a 5% grape seed-supplemented control diet group (G), and a 5% grape seed-supplemented high-fat diet group (HG). Dietary supplementation with grape seeds reduced serum concentrations of lipid peroxides compared with those in the C and HF groups. The hepatic level of lipid peroxides decreased significantly in the grape seed groups compared with that in the C and HF groups. Superoxide dismutase activity in the G group increased significantly compared with that in the C group. Catalase activity tended to be higher by feeding grape seeds. The grape seed diet increased glutathione peroxidase activity in the C group. Glutathione-S-transferase activity increased significantly in the G group compared with that in the C group. Hepatic content of total glutathione increased significantly in the HG group but decreased significantly in the HF group. The ratio of reduced glutathione and oxidized glutathione increased by feeding the grape seed diet. Total vitamin A concentration was significantly higher in HG group than in other groups. Liver tocopherol content of the G and HG groups was significantly higher than that of the control groups. These results suggest that dietary supplementation with grape seeds is beneficial for suppressing lipid peroxidation in high fat-fed rats. PMID:22413034

To investigate the hepatoprotective potential of Sida cordata (Malvaceae) (S. cordata) in experimental rats to validate its traditional claim. Wister albino rats were divided into 6 groups: Group I served as control; Group II served as hepatotoxic (CCl(4) treated) group; Group III, IV and V served as (100, 200 and 400 mg/kg b.w.) S. cordata leaf extract (SCLE) treated groups; Group VI served as positive control (Silymarin) treated group. Liver marker enzymes serum glutamate oxyloacetic transaminase, serum glutamic pyruvic transaminase, pancreatic enzymatic antioxidants superoxide dismutase (SOD), lipid peroxidation, catalase (CAT), reduced glutathione (GSH) were measured and compared along with histopathological studies. Obtained results show that the treatment with SCLE significantly (P<0.05-<0.001) and dose-dependently reduced CCl4 induced elevated serum level of hepatic enzymes. Furthermore, SCLE significantly (up to P<0.001) reduced the lipid peroxidation in the liver tissue and restored activities of defence antioxidant enzymes GSH, SOD and CAT towards normal levels, which was confirmed by the histopathological studies. The results of this study strongly indicate the protective effect of SCLE against CCl(4) induced acute liver toxicity in rats and thereby scientifically support its traditional use.

Eating disorders (EDs) are serious problems among college-age women and may be preventable. An indicated online eating disorder (ED) intervention, designed to reduce ED and comorbid pathology, was evaluated. 206 women (M age = 20 ± 1.8 years; 51% White/Caucasian, 11% African American, 10% Hispanic, 21% Asian/Asian American, 7% other) at very high risk for ED onset (i.e., with high weight/shape concerns plus a history of being teased, current or lifetime depression, and/or nonclinical levels of compensatory behaviors) were randomized to a 10-week, Internet-based, cognitive-behavioral intervention or waitlist control. Assessments included the Eating Disorder Examination (EDE, to assess ED onset), EDE-Questionnaire, Structured Clinical Interview for DSM Disorders, and Beck Depression Inventory-II. ED attitudes and behaviors improved more in the intervention than control group (p = .02, d = 0.31); although ED onset rate was 27% lower, this difference was not significant (p = .28, NNT = 15). In the subgroup with highest shape concerns, ED onset rate was significantly lower in the intervention than control group (20% vs. 42%, p = .025, NNT = 5). For the 27 individuals with depression at baseline, depressive symptomatology improved more in the intervention than control group (p = .016, d = 0.96); although ED onset rate was lower in the intervention than control group, this difference was not significant (25% vs. 57%, NNT = 4). An inexpensive, easily disseminated intervention might reduce ED onset among those at highest risk. Low adoption rates need to be addressed in future research. (c) 2016 APA, all rights reserved).

A health insurance-initiated programme to improve cost-effectiveness of acid-suppressing drugs (ASDs). To evaluate the effect of two different interventions of general practitioner support in reducing drug prescription. A sequential cluster randomized controlled trial with 90 participating general practitioners in a telephone support (TS) group or practice visit (PV) group. TS group received support in phase-1 (first 6 months), but served as control group in phase-2 (6-12 months period). PV group received no intervention in phase-1, serving as the control group for the TS group, but received support in phase-2. Prescription data were extracted from Agis Health Insurance Database. Outcomes were the proportion of responders to drug reduction and the number of defined daily dose (DDD). Differences in users and DDD were analysed using multilevel regression analysis. At baseline, 3424 patients used ASD chronically (211 DDDs, on average). The difference between TS and control groups among responders was 3.2% [95% confidence interval (CI): 0.8; 5.6] and relative risk was 1.26 (95% CI: 1.06; 1.51). The difference between PV and control groups was not relevant (0.4%, 95% CI: -1.99; 2.79 and relative risk: 1.01, 95% CI: 0.82; 1.20). The difference in DDD per patient was -3.0 (95% CI: -8.9; 2.9) and -5.82 (95% CI: -12.4; 0.73), respectively. This health insurance company-initiated intervention had a moderate effect on ASD prescription. In contrast to TS, PVs did not seem to reduce ASD prescription rates.

Rational emotive behaviour therapy (REBT) is effective in reducing distress in several target groups. No other study has tested the mental health effects on adolescents in a high school setting while expanding a Cognitive Behaviour-based therapy, REBT, into the concept of mental health literacy. The format of the ABC model, which is an important element of REBT, functioned as a working manual in and between three sessions. This study tested whether knowledge and practical use of the ABC model increased self-esteem and hope, and reduced symptoms of anxiety and depression, and dysfunctional thinking. Sixty-two high school students with subclinical levels of anxiety and depression were randomly allocated into three groups; three individual REBT sessions, or three individual attentional placebo (ATP) sessions or no sessions (control). However, dysfunctional thinking, self-esteem and hope were not measured in the control group. Repeated measures with ANOVA and t-tests were conducted. Both REBT and ATP significantly reduced symptoms of anxiety and depression, but only REBT was significantly different from the control group at the six-month follow-up. Only REBT significantly reduced dysfunctional thinking, and both REBT and ATP significantly increased self-esteem and hope. REBT had both an immediate and a long-term effect. The findings show the potential positive effects of educating well-documented psychological techniques as ordinary education in school. Further research might contribute to decide whether or not to change the school system by enclosing mental health literacy classes for all students.

Addressing the issue of falls off playground equipment: an empirically-based intervention to reduce fall-risk behaviors on playgrounds.

The present study evaluated the impact of an intervention to reduce fall-risk behaviors on playgrounds among children 6-11 years of age. Children completed posters indicating risky playground behaviors they would and would not do. In the intervention group, video and audio presentations were used to expose children to injury occurrences so that injury vulnerability was communicated in a fear-evoking way. In the control group, children only completed the pre- and post-intervention measures. Significant decreases in intentions to risk-take were obtained in the intervention, but not the control group. Effectiveness did not vary with children's age or sex, but was greater for those scoring high in sensation-seeking. A fear-appeals approach proved successful to reduce intended fall-risk behaviors, particularly for children high in sensation-seeking whose risk-taking is motivated by affect arousal.

Cardiovascular implantable electronic device (CIED) infections are associated with morbidity and mortality. Peri-operative systemic intravenous antibiotic prophylaxis reduces the rate of CIED infections. AIGIS Rx , a polymer envelope implanted with the CIED, releases minocycline and rifampin, and has been introduced to reduce infections. Retrospective review of 184 patients who underwent CIED implantation was conducted. Ninety-two patients were implanted with an AIGIS Rx envelope (AIGIS Rx group) and 92 patients were not implanted with an AIGIS Rx envelope (control group). Data were collected on demographics and risk factors for CIED infections (i.e. congestive heart failure, renal insufficiency, chronic kidney disease, oral anticoagulant use, chronic steroid use, need for lead replacement or revision, temporary pacing, early re-intervention, and having more than two leads in place). Rates of implantation success, major infections and mortality were compared between the AIGIS Rx group and the control group. The AIGIS Rx group had longer hospitalizations (6.8±10.7 days vs 3.1±5.2 days; P=0.001), higher chronic corticosteroid use, higher rates of replacement or revision (51.1% vs 8.7%; P=0.001), and a greater proportion of devices with more than two intracardiac leads (42.4% vs 29.3%; P=0.03) than the control group. Successful implantation occurred in 97% of patients in both groups. Major infection was seen in 5.4% of cases in the AIGIS Rx group and 1.1% of cases in the control group (P=0.048). Device removal was conducted in 3.3% of cases in the AIGIS Rx group compared with 1.1% of cases in the control group (P=0.16). There were two deaths in the AIGIS Rx group. Organisms cultured were meticillin-resistant Staphylococcus aureus, meticillin-susceptible S. aureus and Enterococcus faecalis. The AIGIS Rx group had higher rates of major infection but also higher risk factors compared with the control group. The rate of device extraction and CIED-related mortality was higher in the AIGIS Rx group than in the control group. Copyright © 2017 The Healthcare Infection Society. Published by Elsevier Ltd.

Rectus sheath block (RSB) is an anterior abdominal wall block that reduces postoperative pain associated with midline incisions. This study aims to investigate the effect of ultrasound-guided bilateral RSB (US-BRSB) on postoperative pain and analgesic consumption in patients undergoing laparoscopic gynecologic surgery. Sixty patients who underwent laparoscopic gynecologic surgery were allocated to RSB (n = 30) or control (n = 30) group. A bilateral US-BRSB procedure (30 ml of 0.25% ropivacaine) was performed after induction of general anesthesia in the RSB group. The control group proceeded the surgery without sham block. All patients received fentanyl-based intravenous patient-controlled analgesia and rescue analgesics upon demand. Pain was scored by a blinded observer using a verbal numerical rating scale (VNRS) at rest while coughing at 0, 1, 6, 12, 24, and 48 h after postanesthesia care unit (PACU) admission. The primary outcome was the total number of rescue analgesics used in the 48-h postoperative period. At 0 h, VNRS were lower in the RSB group than in the control, both at rest (median VNRS 4.5 vs. 5, p = 0.02) and while coughing (median VNRS 6 vs. 7, p = 0.004). At 6 h, VNRS scores were lower in the RSB group than in the control while coughing (median VNRS 3 vs. 5, p = 0.01). Fentanyl use as rescue analgesics in the PACU was significantly lower in the RSB group than in the control (27.7 ± 32.1 vs. 53.3 ± 33.7 µg, respectively; p = 0.004). At 48 h postoperatively, the total number of rescue analgesics administered were significantly fewer in the RSB group than in the control (2.5 ± 2.5 vs. 3.9 ± 2.6, respectively; p = 0.04). US-BRSB reduces the immediate postoperative pain and opioid consumption during the early postoperative period. CLINICALTRIALS. NCT02476799, https://clinicaltrials.gov/ct2/show/NCT02476799 .

The purpose of this study was to determine whether an alert to get up once per hour while at work would reduce sitting time, increase sit-to-stand transitions, and improve perceived wellness in women with sedentary jobs. Female university staff and administrators (48 ± 10 years) were randomly assigned to control-control (CC) (n = 22) or control-intervention (CI) (n = 22) groups. Both used a thigh-worn postural-based activity monitor for 2 weeks. The CC group maintained normal behaviors, whereas the CI group maintained behaviors during control week, but received hourly alerts on their computer during work hours in the intervention week. Time sitting and sit-to-stand transitions during an 8.5-hour workday were examined. A perceived wellness survey was completed at baseline and after the control and intervention weeks. Among all participants (N = 44) during the control week, 68% of the workday was spent sitting and 41 sit-to-stand transitions occurred. An analysis of variance revealed no statistically significant differences in variables over time (P > .05). There was a significant increase in perceived wellness from baseline in both groups (P ≤ .05). Perceived wellness showed no statistically significant difference between groups. The intervention had no statistically significant effect on sitting time or sit-to-stand transitions. Participation improved perceived wellness in the absence of behavior change.

The aim of this study was to investigate the effects of oral carbohydrate solution (CHO) on perioperative discomfort, biochemistry, hemodynamics, and patient satisfaction in elective surgery patients under general anesthesia. Sixty cases in ASA I-II group who were planned to have operation under general anesthesia were included in the study. The cases were randomly divided into two groups having 30 subjects in each. The patients in the study group were given CHO in the evening prior to the surgery and 2-3 hr before the anesthesia while routine fasting was applied in the control group. In the study group; 2-3 hr before the surgery; malaise, thirst, hunger, and weakness; just before the surgery malaise, thirst, hunger, and fatigue; 2 hr after the operation thirst, hunger, weakness, and concentration difficulty; 24 hr after the operation malaise and weakness were found significantly lower. Fasting blood glucose (FBG) level was found to be higher in the control group at the 90th min of the operation. Gastric volumes were higher in the control group; gastric pH values were found significantly higher in the study group. The level of anxiety and depression risk rate were found lower in the study group. In conclusion, preoperative CHO reduces perioperative discomfort and improves perioperative well being when compared to overnight fasting.

Objectives. We investigated whether the Kidskin sun protection intervention increased children’s body mass index by reducing the time spent outdoors at midday. Methods. The Kidskin sun protection intervention involved 1614 Australian school children assigned to 1 of 3 groups: a control group, a moderate-intervention group, or a high-intervention group. Schools in the control group received the standard health curriculum and schools in the intervention groups received a multicomponent intervention. Outcomes included time spent outdoors and nevus development (a marker of melanoma risk). Height and weight were measured at 3 time points. Body mass index was transformed into age- and gender-specific z scores; z scores at each age were modeled simultaneously. Time spent outdoors at ages 10 and 12 years was analyzed using a linear mixed effects modeling. Results. The proportion of children who were overweight or obese increased with age. The moderate-intervention and control groups had a minimal increase in z score over time, and the z score for the high-intervention group decreased over time. There were no differences among groups with respect to total time outdoors at any age. Conclusions. It is possible to reduce the time children spend outdoors when ultraviolet radiation is high without producing an unfavorable effect on the children’s body mass index. PMID:17194858

It is suggested that masticatory dysfunction affects the central nervous system; however, the underlying mechanism remains unknown. Brain-derived neurotrophic factor (BDNF) and its receptor, TrkB, are known to play important roles in memory and learning. In this study, we examined the effects of mastication on memory, the expression levels of BDNF and TrkB, and the number of neurons in the hippocampus of mice. Male C57 BL/6J mice (3 weeks old) were randomly divided into the control group (N = 7) fed chow pellets and the experimental group (N = 7) fed a liquid diet, which reduces mastication during eating. At 14 weeks of age, we performed a passive avoidance test and found that memory and learning ability were impaired in the experimental group compared with the control group. After the behavioral experiment, brains were harvested and analyzed morphologically and biochemically. In the hippocampus of the experimental group, the expression levels of BDNF were significantly higher, whereas those of TrkB were lower than those of the control group. In the cerebral cortex, these levels remained unchanged between the two groups. The ratio of phospho-p44/42 ERK/pan ERK, a downstream molecule of BDNF/TrkB signaling, in the experimental group was significantly lower than that of the control group in the cortex and hippocampus. The number of pyramidal neurons in the hippocampus was lower in the experimental group than in the control group. These findings suggest that reduced mastication induced by a liquid diet in early childhood may impair memory and learning ability, accompanied by neuronal loss in the hippocampus. © 2014 Wiley Periodicals, Inc.

Parecoxib, a selective cyclooxygenase-2 inhibitor, may reduce postoperative pain without increasing bleeding when administered before surgery. We randomly assigned 62 patients scheduled for total hip arthroplasty to the following IV dosing schedule: 1) placebo at induction, at wound closure, and 12 h after induction (control); 2) parecoxib 40 mg at induction, placebo at wound closure, and parecoxib 40 mg 12 h after induction (pre); or, 3) placebo at induction, parecoxib 40 mg at wound closure, and parecoxib 40 mg 12 h after induction (post). Pain scores at rest and with movement were recorded every 4 h for 24 h using a visual analog scale. Treatment side effects were recorded every 4 h. Red cell loss for 5 days after surgery was calculated. Postoperative pain scores were less in the pre and post groups than in the control group. Postoperative bleeding was similar in the three groups. There were no significant differences between the pre and post groups, nor was their any trend suggesting a preemptive analgesic efficacy from preincision administration of parecoxib. Morphine use in the Postanesthesia Care Unit was reduced in the pre and post groups compared with the control group (14.2 +/- 2.0, and 15.7 +/- 2.0, vs 20.4 +/- 2.3 mg), although the trend was only significant (P < 0.05) in the pre group. The first pain score was also reduced in the pre and post groups compared to the control group (56.1 +/- 7.5 and 64.2 +/- 7.0 vs 78.3 +/- 5), but this was also only significant for the pre group (P = 0.001). The delay for first analgesic demand was increased for both the pre and post group compared to the control group (38 +/- 9 and 28.2 +/- 6.6 vs 18 +/- 6 min) but, again, this was only significant for the pre group (P = 0.05). Twenty-four hour consumption of morphine was similar in the pre (26 +/- 12 mg) and post groups (25 +/- 13 mg); both were significantly less than in the control group (47 +/- 27 mg, P < 0.001). Administration of parecoxib before hip arthroplasty did not provide preemptive analgesia. There was a trend towards improved analgesia immediately after surgery with preincision administration, consistent with the expected time course of nonsteroidal antiinflammatory drug's effect. Perioperative parecoxib administration, consisting of two injections spaced 12 h apart, improved postoperative analgesia over the first 24 h without increasing bleeding.

[Purpose] We compared the effectiveness of dry needling with a classical physiotherapy program in patients with chronic low-back pain caused by lumbar disc hernia (LHNP). [Subjects and Methods] In total, 34 subjects were allocated randomly to the study (n=18) and control groups (n=16). In the study group, dry needling was applied using acupuncture needles. The control group performed a home exercise program in addition to hot pack, TENS, and ultrasound applications. Pain was assessed with the short form of the McGill Pain Questionnaire. The number of trigger points and their pressure sensitivity were evaluated with a physical examination (palpation). The Beck Depression Inventory was used to assess depression. The Tampa Kinesiophobia Scale was used to assess fear of movement. [Results] In the study group, the calculated Cohen's effect sizes were bigger than those in the control group in terms of pain, trigger point-related variables, and fear of movement. Effect sizes for reducing depressive symptoms were similar in both groups. [Conclusion] These results suggest that dry needling can be an effective treatment for reducing pain, number of trigger points, sensitivity, and kinesiophobia in patients with chronic low-back pain caused by lumbar disc hernia.

The current study investigated whether biofeedback training aimed at increasing respiratory sinus arrhythmia (RSA), a measure of cardiac vagal modulation, can reduce depressive symptoms in patients after cardiac surgery. This randomized controlled study enrolled 26 patients after first-time cardiac surgery. The patients were randomly assigned to an RSA-biofeedback group (N = 13) or to a treatment as usual group (N = 13). The biofeedback training consisted of five 45 min sessions designed to increase RSA. The outcome was assessed as changes in RSA and in the Centre for Epidemiologic Studies of Depression (CES-D) values from pre- to post-training. Both groups were comparable for demographic and biomedical characteristics. RSA increased significantly in patients who underwent RSA-biofeedback compared to controls. Moreover, the CES-D scores were reduced significantly from pre- to post-training in the RSA-biofeedback group compared to the controls. Changes in RSA were inversely related to changes in CES-D scores from pre- to post-training. These findings extend the effectiveness of RSA-biofeedback for increasing vagal modulation as well as for reducing depressive symptoms in post-surgical patients. Overall, the current study also suggests that this biobehavioral intervention may add to the efficacy of postoperative risk reduction programs and rehabilitation protocols in cardiac surgery patients.

Does single use of an autologous transfusion system in TKA reduce the need for allogenic blood?: a prospective randomized trial.

Mechanical autotransfusion systems for washed shed blood (WSB) were introduced to reduce the need for postoperative allogenic blood transfusions (ABTs). Although some authors have postulated decreased requirements for ABT by using autologous retransfusion devices, other trials, mostly evaluating retransfusion devices for unwashed shed blood (USB), verified a small or no benefit in reducing the need for postoperative ABT. Because of these contradictory findings it is still unclear whether autologous retransfusion systems for WSB can reduce transfusion requirements. We therefore asked whether one such autologous transfusion system for WSB can reduce the requirements for postoperative ABT. In a prospective, randomized, controlled study, we enrolled 151 patients undergoing TKA. In Group A (n=76 patients), the autotransfusion system was used for a total of 6 hours (intraoperatively and postoperatively) and the WSB was retransfused after processing. In Control Group B (n=75 patients), a regular drain without suction was used. We used signs of anemia and/or a hemoglobin value less than 8 g/dL as indications for transfusion. If necessary, we administered one or two units of allogenic blood. Twenty-three patients (33%) in Group A, who received an average of 283 mL (range, 160-406 mL) of salvaged blood, needed a mean of 2.1 units of allogenic blood, compared with 23 patients (33%) in Control Group B who needed a mean of 2.1 units of allogenic blood. We found the use of an autotransfusion system did not reduce the rate of postoperative ABTs. Level II, therapeutic study.

The article arises from a research project investigating the effectiveness of safety training on changing attitudes toward safety issues. Followed by the training intervention was observed that employees' helplessness decreased. The researchers have come to the idea of investigating how safety training can reduce perceived helplessness. Thus, this research examined the effectiveness of safety training on reducing employees' helplessness with attention to the mediating role of attitude toward safety issues. The current study was an experimental study with the control group. A total of 204 (101 experimental group and 103 control group) completed safety attitude questionnaire and perceived helplessness before a safety training course including four 90-min sessions over 4 consecutive days in Esfahan Steel Company in 2012 between October and December. Only members of the experimental group participated in this course. These questionnaires, approximately 30 days later, again were run on members of both groups. Data were analyzed using descriptive indexes, t-, and F-test. RESULTS by comparing the two groups showed that safety training was effective only on individuals with perceived low helplessness (p = 0.02). In individuals with perceived high helplessness, safety training only with changing safety attitudes can reduce the perceived helplessness.

Persistent whiplash associated disorders (WAD) have been associated with alterations in kinesthetic sense and motor control. The evidence is however inconclusive, particularly for differences between WAD patients and patients with chronic non-traumatic neck pain. The aim of this study was to investigate motor control deficits in WAD compared to chronic non-traumatic neck pain and healthy controls in relation to cervical range of motion (ROM), conjunct motion, joint position error and ROM-variability. Participants (n = 173) were recruited to three groups: 59 patients with persistent WAD, 57 patients with chronic non-traumatic neck pain and 57 asymptomatic volunteers. A 3D motion tracking system (Fastrak) was used to record maximal range of motion in the three cardinal planes of the cervical spine (sagittal, frontal and horizontal), and concurrent motion in the two associated cardinal planes relative to each primary plane were used to express conjunct motion. Joint position error was registered as the difference in head positions before and after cervical rotations. Reduced conjunct motion was found for WAD and chronic neck pain patients compared to asymptomatic subjects. This was most evident during cervical rotation. Reduced conjunct motion was not explained by current pain or by range of motion in the primary plane. Total conjunct motion during primary rotation was 13.9 degrees (95% CI; 12.2-15.6) for the WAD group, 17.9 degrees (95% CI; 16.1-19.6) for the chronic neck pain group and 25.9 degrees (95% CI; 23.7-28.1) for the asymptomatic group. As expected, maximal cervical range of motion was significantly reduced among the WAD patients compared to both control groups. No group differences were found in maximal ROM-variability or joint position error. Altered movement patterns in the cervical spine were found for both pain groups, indicating changes in motor control strategies. The changes were not related to a history of neck trauma, nor to current pain, but more likely due to long-lasting pain. No group differences were found for kinaesthetic sense.

Alcohol exposure during development has been shown to alter a variety of social behaviors in both humans and rodents. Sexual behavior in rodents has been well characterized and lends itself to a detailed investigation of the manner in which ethanol impacts this particular social behavior. Rats were exposed to ethanol during both the prenatal and early postnatal period (ET). Control groups included rats exposed to the administration procedures alone (intubated-control) and nontreated controls (NC). Sexual behavior of intact naïve female rats in estrus was assessed in adulthood (approximately postnatal day 90) and activity was measured by the number of crossings between chambers in the 3-chamber test apparatus. A separate study examined the olfactory preferences for 4 odors by intact naïve female rats in all 3 groups. The 4 odors were the odors resulting from 1 hour of occupation of the test chamber by an intact male, 1 hour of occupation of the test chamber by a gonadectomized male, 0.5 ml of urine from an intact male, and 0.5 ml of urine from a gonadectomized male. ET female rats showed a reduced return latency after ejaculation compared to both control groups. There was a trend toward a reduction in percent exits after all forms of male behavior in the ET animals compared to the control groups. No significant differences across groups were seen in the lordosis quotient, activity, or the behavior of the nonexperimental male. ET female rats showed a reduced preference for the odor from the intact male compared to both control groups and a reduced preference for the odor from the gonadectomized male compared to NC females only. These data suggest that ethanol exposure during the prenatal and postnatal period in females alters sexual motivation and changes the processing of olfactory cues and possibly coital cues from male rats.

To evaluate the efficacy of topical lidocaine 2% gel in reducing the pain associated with the insertion of nasal continuous positive airway pressure (nCPAP) prongs in preterm infants. A pilot randomized controlled trial. Sixty preterm infants, categorized into lidocaine (n=30) and control groups (n=30). The primary outcome was Premature Infant Pain Profile (PIPP) score, secondary outcomes included salivary cortisol, presence of cry, the duration of first cry, and adverse effects of lidocaine. There were no statistically significant differences between lidocaine and control groups regarding PIPP scores (mean±SD: 7.2±2.3 vs. 9.3±3.0, respectively, P=0.086). None of the infants in the lidocaine group had severe pain defined as a PIPP score>12, compared with 3 (10%) infants in the control group (P=0.056). Salivary cortisol concentrations were not significantly different between the lidocaine and control groups (mean±SD: 2.57±1.79 vs. 4.82±1.61 μg/dL, respectively, P=0.11). Standardized effect sizes for topical lidocaine were medium to large for reduction in PIPP scores and large for reduction in salivary cortisol (Cohen d=-0.78 and -1.32, respectively). No adverse effects were reported in infants receiving lidocaine. Our data suggest that topical lidocaine did not reduce the pain associated with the insertion of nCPAP prongs in preterm infants. However, the trends for lower PIPP scores in the lidocaine group and the effect sizes for lidocaine on PIPP scores and salivary cortisol were large enough so that a large-scale randomized clinical trial is warranted to confirm or refute our results. Such a study should compare 2 or more active pain interventions during nCPAP application, rather than evaluating a single intervention versus placebo or no treatment.

Administration of a beta-blocker, pindolol, was utilized in the premedication of patients selected for tonsillectomies (dissection), to study anxiolytic effects. A curious result observed was that bleeding during and after operation in patients on pindolol was remarkably reduced compared to those not on beta-blocker treatment. This effect was further explored in a small controlled study. Nineteen patients were given pindolol, 5 mg the evening before and on the morning, an hour prior to surgery. Seventeen controls were on placebos. The amount of bleeding was measured in both groups. Patients on pindolol show significantly reduced bleeding when compared to controls (1.77 +/- 1.15 ml versus 7.30 +/- 6.05 ml; p less than 0.005). Coagulation and fibrinolytic profiles were studied in a number of patients in both groups attempting to clarify the cause of the reduced bleeding. The results will be reported. This preliminary study shows that pindolol is a useful drug for controlling bleeding in tonsillectomies. To our knowledge the haemostatic properties of pindolol have been reported before.

AIM: To attempt rectal administration of rebamipide in the treatment of ischemic colitis patients with ulcers, and evaluate its effects. METHODS: We compared 9 ischemic colitis patients (2 men, 7 women) with ulcers treated by bowel rest only from 2000 to 2005 (conventional therapy group), with 6 patients (2 men, 4 women) treated by rebamipide enema therapy in 2006 (rebamipide enema therapy group) and analyzed the mean duration of fasting and hospitalization, degree of ulcer healing, and decrease in WBC count for the two groups. RESULTS: The mean duration of fasting and hospitalization were 2.7 ± 1.8 d and 9.2 ± 1.5 d in the rebamipide group and 7.9 ± 4.1 d and 17.9 ± 6.8 d in the control group, respectively, and significantly reduced in the rebamipide group (t = -2.915; P = 0.0121 and t = -3.054; P = 0.0092). As for the degree of ulcer healing at 7 d after admission, the ulcer score was reduced by 3.5 ± 0.5 (points) in the rebamipide group and 2.8 ± 0.5 (points) in the control group (t = 1.975; P = 0.0797), while the decrease in WBC count was 120.0 ± 55.8 (× 102/μL) in the rebamipide group and 85.9 ± 56.8 (× 102/μL) in the control group (t = 1.006; P = 0.3360). CONCLUSION: In left-sided ischemic colitis patients with ulcers, rebamipide enema therapy significantly reduced the duration of fasting and hospitalization, recommending its use as a new and effective therapeutic alternative.

Diabetic ketoacidosis (DKA) may cause brain injuries in children. The mechanisms responsible are difficult to elucidate because DKA involves multiple metabolic derangements. We aimed to determine the independent effects of hyperglycemia and ketosis on cerebral metabolism, blood flow, and water distribution. We used magnetic resonance spectroscopy to measure ratios of cerebral metabolites (ATP to inorganic phosphate [Pi], phosphocreatine [PCr] to Pi, N-acetyl aspartate [NAA] to creatine [Cr], and lactate to Cr) and diffusion-weighted imaging and perfusion-weighted imaging to assess cerebral water distribution (apparent diffusion coefficient [ADC] values) and cerebral blood flow (CBF) in three groups of juvenile rats (hyperglycemic, ketotic, and normal control). ATP-to-Pi ratio was reduced in both hyperglycemic and ketotic rats in comparison with controls. PCr-to-Pi ratio was reduced in the ketotic group, and there was a trend toward reduction in the hyperglycemic group. No significant differences were observed in NAA-to-Cr or lactate-to-Cr ratio. Cortical ADC was reduced in both groups (indicating brain cell swelling). Cortical CBF was also reduced in both groups. We conclude that both hyperglycemia and ketosis independently cause reductions in cerebral high-energy phosphates, CBF, and cortical ADC values. These effects may play a role in the pathophysiology of DKA-related brain injury.

Though breast feeding is natural, during the first 2-3 days, when enough breast milk is not available with mother, she may introduce bottle feeding erroneously for improving nutrition to her baby. We studied the effect of antenatal expression of breast milk at term in reducing breast feeding failure as compared to conventional method of initiation of breast feeding. A prospective study was carried out in 180 booked cases at term. Daily expression of breast milk at least once a day after 37 weeks of pregnancy was introduced in randomly selected 90 pregnant ladies. Prior examination was done to exclude any inverted or cracked nipples and appropriate treatment instituted. The study group who expressed breast milk daily after 37 weeks did not find it difficult to initiate breast feeding after vaginal or cesarean delivery. Sufficient milk started flowing within half an hour of initiation of breast feeding in most 85 (94.4%) subjects of study group as compared to 63 (70%) patients of control group, which was statistically significant. There was no increase in any delivery complication. There were two partial breast feeding failures in control group but none in study group. Daily antenatal breast milk expression after 37 completed weeks of pregnancy significantly reduced the time for establishing full breast feeding and reduced breast feeding failures.

We hypothesized that continuous right thoracic paravertebral block, following bolus initiation, decreases opioid consumption after right-lobe hepatectomy in patients receiving patient-controlled intravenous analgesia with sufentanil. Patients undergoing right-lobe hepatectomy with a right thoracic paravertebral catheter placed at T7 30 minutes before surgery were randomly assigned to receive through this catheter either a 10-mL bolus of 0.2% ropivacaine before emergence, followed by a continuous infusion of 6 mL/h for 24 hours (PVB group), or saline at the same scheme of administration (control group). All patients were started on patient-controlled intravenous analgesia with sufentanil in the postanesthesia care unit. The primary outcome measure was total sufentanil consumption during the first 24 postoperative hours. P = 0.05 was considered as significant. For the multiple comparisons of data at 5 different time points, the P value for the 0.05 level of significance was adjusted to 0.01. Sixty-six patients were assessed for eligibility, and a PVB catheter was successfully placed for 48 patients. Data were analyzed on 22 patients in group PVB and 22 patients in the control group. The cumulative sufentanil consumption in the PVB group (54.3 ± 12.1 μg) at 24 postoperative hours was more than 20% less than that of the control group (68.1 ± 9.9 μg) (P < 0.001). There was also a significant difference in pain scores (numerical rating scale) between groups, where the PVB group had lower scores than did the control group at rest and with coughing for the first 24 hours (P < 0.001). Continuous right thoracic paravertebral block, following bolus initiation, has an opioid-sparing effect on sufentanil patient-controlled intravenous analgesia for right-lobe hepatectomy patients and reduces numerical rating scale pain scores at rest and with coughing in the first 24 postoperative hours.

The objectives of this study were to assess the efficacy of lifestyle intervention on gestational weight gain in pregnant women with normal and above normal body mass index (BMI) in a randomized controlled trial. A total of 116 pregnant women (<20 weeks of pregnancy) without diabetes were enrolled and 113 pregnant women completed the program. Participants were randomized into intervention and control groups. Women in the intervention group received weekly trainer-led group exercise sessions, instructed home exercise for 3-5-times/week during 20-36 weeks of gestation, and dietary counseling twice during pregnancy. Participants in the control group did not receive the intervention. All participants completed a physical activity questionnaire and a 3-day food record at enrolment and 2 months after enrolment. The participants in the intervention group with normal pre-pregnancy BMI (≤24.9 kg/M2, n = 30) had lower gestational weight gain (GWG), offspring birth weight and excessive gestational weight gain (EGWG) on pregnancy weight gain compared to the control group (n = 27, p < 0.05). Those weight related-changes were not detected between the intervention (n = 27) and control group (n = 29) in the above normal pre-pregnancy BMI participants. Intervention reduced total calorie, total fat, saturated fat and cholesterol intake were detected in women with normal or above normal pre-pregnancy BMI compared to the control group (p < 0.05 or 0.01). Increased physical activity and reduced carbohydrate intake were detected in women with normal (p < 0.05), but not above normal, pre-pregnancy BMI at 2 months after the onset of the intervention compared to the control group. The results of the present study demonstrated that the lifestyle intervention program decreased EGWG, GWG, offspring birth weight in pregnant women with normal, but not above normal, pre-pregnancy BMI, which was associated with increased physical activity and decreased carbohydrate intake.

Screen time, defined as time spent watching television, DVDs, or videos or playing computer or video games, has been related to serious health consequences in children, such as impaired language acquisition, violent behaviour, tobacco smoking and obesity. Our aim was to determine if a simple intervention aimed at preschool-aged children, applied at the health maintenance visits, in the primary care setting, would be effective in reducing screen time. We used a two group randomized controlled trial design. Two- to 6-year-old children and their parents were randomly assigned to receive an intervention to reduce their screen time, BMI and parental report of aggressive behaviour. At the end of the intervention we made home visits at 2, 6 and 9 months and the parents completed questionnaire. Parents in the intervention group reported less screen time and less aggressive behaviour than those in the control group but there were no differences in BMI z scores. This study shows that a preschool-based intervention can lead to reductions in young children's television/video viewing. © 2014 John Wiley & Sons Ltd.

Teachers constitute one of the professional collectives most affected by psychological problems. The purpose of this quasi-experimental study is to examine the efficacy of a mindfulness training programme to reduce psychological distress in a group of teachers. The sample comprised 68 teachers of Secondary School Education, from various public schools; half of them formed the experimental group, and the another half the control group. The levels of psychological distress were measured, in both groups, by the Symptom Checklist-90-R (SCL-90-R) before and after the application of the programme. Statistical analysis shows the significant reduction of three general measures of psychological distress (Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total), as well in all its dimensions (somatization, obsessive-compulsive, interpersonal sensibility, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism), in the experimental group compared with the control group. Follow-up measures show that these results were maintained for four months after termination of the intervention in the experimental group.
