Photothermal destruction of hair shaft melanin with intense pulsed light (IPL) and neodymium:yttrium-aluminum-garnet (Nd:YAG) laser has become an effective treatment of hair removal. Our aim was to compare efficacy, satisfactory levels, safety, and side effects of Nd:YAG and IPL in hair reduction. This was a prospective randomized intrapatient, right-left, assessor-blinded comparison of Nd:YAG vs IPL. There were 38 volunteers recruited. Seven sessions were performed. Hair count, efficacy, and side effects were compared before and after each treatment and 6 months after the last treatment. In respect of 12 volunteers, we have examined the reduction in hair after 18 months. Initially, there was no significant difference between the numbers of hair follicles. There was significant hair reduction after each treatment on the Nd:YAG-treated side. The hair reduction became significant after the third treatment with IPL. Comparison of the efficacy of the two devices on each visits showed no significant difference. There was statistically lower pain score on the IPL-treated side and statistically higher erythema, burning sensation, and edema on the Nd:YAG-treated side. Statistically lower side effect score was observed on the IPL-treated side. Eight months after the last treatment, there was significant hair reduction both on the Nd:YAG and on the IPL-treated side, and there was no difference between the efficacy. The patient satisfaction scores were higher with the IPL. Unwanted hair can be reduced by both systems safely and effectively; however, IPL has less side effects and higher satisfaction scores. © 2017 Wiley Periodicals, Inc.

To evaluate the effect of toothpaste treatments on levels of oral volatile sulphur compounds (VSCs) measured by gas chromatography in two clinical studies. These were blinded, randomised, controlled, crossover studies with 16 (study A) or 20 (study B) healthy volunteers between the ages of 19-54. Study A: breath samples were collected at baseline, immediately and lhr after brushing. Four dentifrices (Zinc A, Zinc B, commercially available triclosan dentifrice and zinc free control) were evaluated. Study B: breath samples were collected at baseline, immediately, 1, 2, 3 and 7 hours after treatment. Subjects consumed a light breakfast then provided an additional breath sample between baseline assessment and treatment. Two dentifrices (gel-to-foam and a commercially available triclosan dentrifrice) were evaluated. Breath samples were collected in syringes and analysed for VSCs (hydrogen sulphide, methyl mercaptan and Total VSCs) utilising gas chromatography (GC) with flame photometric detection. Study A: immediately after treatment, a statistically significant reduction in VSCs from baseline was observed for Zinc A product only. A statistically significant reduction in VSCs from baseline was observed after 1 hour for all products. Both zinc products exhibited a significantly greater reduction from baseline VSCs than Colgate Total and Control at all time points. Study B: a statistically significant reduction in VSCs from baseline was observed at all time points for both products. The gel-to-foam product exhibited significantly greater reduction from baseline Total VSC concentration than Colgate Total at all time points from 1 hour post-treatment. Control of oral malodour by toothpaste treatment, evaluated as VSC levels using GC, has been demonstrated. Zinc is effective at reducing VSCs and the efficacy of zinc is formulation dependent. A gel-to-foam dentifrice was more effective at reducing VSCs than Colgate Total up to 7 hours.

To describe patients' perceptions of minimum worthwhile and desired reductions in pain and disability upon commencing treatment for chronic low back pain. Descriptive study nested within a community-based randomized controlled trial on prolotherapy injections and exercises. A total of 110 participants with chronic low back pain. Interventions. Prior to treatment, participants were asked what minimum percentage reductions in pain and disability would make treatment worthwhile and what percentage reductions in pain and disability they desired with treatment. Minimum worthwhile reductions and desired reductions in pain and disability. Median (inter-quartile range) minimum worthwhile reductions were 25% (20%, 50%) for pain and 35% (20%, 50%) for disability. This compared with desired reductions of 80% (60%, 100%) for pain and 80% (50%, 100%) for disability. The internal consistency between pain and disability responses was high (Spearman's coefficient of association of 0.81 and 0.87, respectively). A significant association existed between minimum worthwhile reductions and desired reductions, but no association was found between these two factors and patient age, gender, pain severity or duration, disability, anxiety, depression, response to treatment, or treatment satisfaction. Inquiring directly about patients' expectations of reductions in pain and in disability is important in establishing realistic treatment goals and setting benchmarks for success. There is a wide disparity between the reductions that they regard as minimum worthwhile and reductions that they hope to achieve. However, there is a high internal consistency between reductions in pain and disability that they expect.

Acarbose (AC) and Sitagliptin (STGP) are oral hypoglycemic agents currently used either alone or in conjunction with human diabetic (Type 2) patients. AC has been used with diabetic cats, but not STGP thus far. Therefore, the objective of this study was to determine the potential use of AC or STGP alone and in combination for diabetic cats, by observing their effect on short-term post-prandial serum glucose, insulin, and incretin hormone (active glucagon-like peptide-1 (GLP-1) and total glucose dependent insulinotropic polypeptide (GIP)) concentrations in five healthy cats, following ingestion of a meal with maltose. All treatments tended (p<0.10; 5-7.5% reduction) to reduce postprandial glucose area under the curve (AUC), with an accompanying significant reduction (p<0.05, 35-45%) in postprandial insulin AUC as compared to no treatment. Meanwhile, a significant increase (p<0.05) in postprandial active GLP-1 AUC was observed with STGP (100% higher) and combined treatment (130% greater), as compared to either AC or no treatment. Lastly, a significant reduction (p<0.05) in postprandial total GIP AUC was observed with STGP (21% reduction) and combined treatment (7% reduction) as compared to control. Overall, AC, STGP, or combined treatment can significantly induce positive post-prandial changes to insulin and incretin hormone levels of healthy cats. Increasing active GLP-1 and reducing postprandial hyperglycemia appear to be the principal mechanisms of combined treatment. Considering the different, but complementary mechanisms of action by which AC and STGP induce lower glucose and insulin levels, combination therapy with both these agents offers great potential for treating diabetic cats in the future.

Progressive brain volume reductions have been described in schizophrenia, and an association with antipsychotic exposure has been reported. We compared percentage changes in grey and white matter volume from baseline to month 12 in 23 previously antipsychotic-naïve patients with a first episode of schizophrenia or schizophreniform disorder who were treated with the lowest effective dose of flupenthixol decanoate depot formulation, with 53 matched healthy individuals. Total antipsychotic dose was precisely calculated and its relationship with brain volume changes investigated. Relationships between volumetric changes and treatment were further investigated in terms of treatment response (changes in psychopathology and functionality) and treatment-related adverse-events (extrapyramidal symptoms and weight gain). Excessive cortical volume reductions were observed in patients [-4.6 (6.6)%] v. controls [-1.12 (4.0)%] (p = 0.009), with no significant group differences for changes in subcortical grey matter and white matter volumes. In a multiple regression model, the only significant predictor of cortical volume change was total antipsychotic dose received (p = 0.04). Cortical volume change was not significantly associated with the changes in psychopathology, functionality, extrapyramidal symptoms and body mass index or age, gender and duration of untreated psychosis. Brain volume reductions associated with antipsychotic treatment are not restricted to poor outcome patients and occur even with the lowest effective dose of antipsychotic. The lack of an association with poor treatment response or treatment-related adverse effects counts against cortical volume reductions reflecting neurotoxicity, at least in the short term. On the other hand, the volume reductions were not linked to the therapeutic benefits of antipsychotics.

Nonsteroidal anti-inflammatory drugs (NSAIDs) provide fast and effective acute pain relief, but systemic administration has increased risk for some adverse reactions. The diclofenac epolamine 1.3% topical patch (DETP) is a topical NSAID with demonstrated safety and efficacy in treatment of acute pain from minor soft tissue injuries. Significant pain reduction has been observed in clinical trials within several hours following DETP application, suggesting rapid pain relief; however, this has not been extensively studied for topical NSAIDs in general. This retrospective post-hoc analysis examined time to onset of significant pain reduction after DETP application compared to a placebo patch for patients with mild-to-moderate acute ankle sprain, evaluating the primary efficacy endpoint from two nearly identical studies. Data from two double-blind, randomized, parallel-group, placebo-controlled studies (N = 274) of safety and efficacy of the DETP applied once daily for 7 days for acute ankle sprain were evaluated post-hoc using statistical modeling to estimate time to onset of significant pain reduction following DETP application. Pain on active movement on a 100 mm Visual Analog Scale (VAS) recorded in patient diaries; physician- and patient-assessed tolerability; and adverse events. DETP treatment resulted in significant pain reduction within approximately 3 hours compared to placebo. Within-treatment post-hoc analysis based on a statistical model suggested significant pain reduction occurred as early as 1.27 hours for the DETP group. The study may have been limited by the retrospective nature of the analyses. In both studies, the DETP was well tolerated with few adverse events, limited primarily to application site skin reactions. The DETP is an effective treatment for acute minor soft tissue injury, providing pain relief as rapidly as 1.27 hours post-treatment. Statistical modeling may be useful in estimating time to onset of pain relief for comparison of topical and oral NSAIDs.

To determine the predictors of drusen reduction in eyes with nonexudative age-related macular degeneration (ARMD) treated with subthreshold infrared (810 nm) diode laser macular grid photocoagulation. Additionally, to determine the relationship of laser-induced drusen reduction and best-corrected visual acuity (BCVA) 18 months after laser treatment. Randomized controlled clinical trial. Fifty patients (100 eyes) with bilateral nonexudative ARMD were enrolled at two centers. One eye of each patient was randomized to the observation; the other eye was treated with 48 subthreshold (invisible end point) applications of infrared (810 nm) diode laser in a macular grid pattern. The eyes that received subthreshold laser treatment were compared with the eyes that received no treatment. The baseline fundus characteristics (number, size, and distribution of drusen, as well as focal hyperpigmentation) from two macula areas (central 1500 micro diameter, pericentral 1500 micro ring area) on stereo color photographs, the number of laser-induced lesions, and the area of laser induced retinal pigment epithelial (RPE) lesions on fluorescein angiography 3 months after treatment were studied as predictors of major drusen reduction (> or = 50% drusen reduction from baseline) 18 months after laser treatment. BCVA at baseline and 18 months later was compared in observation eyes and in laser-treated eyes. Eighteen months after randomization, 24 (48%) of 50 eyes treated with subthreshold laser had major drusen reduction compared with three (6%) of 50 observation eyes (P =.00001). At 3 months post-treatment in laser-treated eyes with major drusen reduction, the mean number of laser-induced lesions on fluorescein angiography was 30.7 and the mean area of RPE change was 0.81 mm(2) compared with 14.8 laser-induced lesions and 0.35 mm(2) area of RPE change in eyes without major drusen reduction (P =.0001 and P =.0003, respectively). At baseline, fundus characteristics were not significantly different between observation eyes and laser-treated eyes or between the major drusen reduction group and the nonmajor drusen reduction group. At 18 months after treatment, BCVA was not significantly different in laser-treated eyes and in observation eyes. Subthreshold infrared (810 nm) diode laser macular grid photocoagulation in eyes with nonexudative ARMD significantly reduced drusen 18 months after laser treatment. Both the number of subthreshold laser lesions and the area of RPE changes visible on fluorescein angiography 3 months after treatment appeared to be predictors for major drusen reduction 18 months after treatment. However, it remains to be determined whether laser-induced drusen reduction is beneficial for visual acuity or reduces the incidence of choroidal neovascularization (CNV) in eyes with nonexudative ARMD.

Carboxylesterase 1 is the enzyme involved in methylphenidate (MPH) metabolism. The aim of this study was to evaluate the association between a -75 T>G polymorphism and appetite reduction in children with attention-deficit/hyperactivity disorder (ADHD). A sample of 213 children with ADHD was investigated. The primary outcome was appetite reduction measured by the Barkley Stimulant Side Effect Rating Scale applied at baseline, at 1 and 3 months of treatment. MPH doses were augmented until no further clinical improvement or significant adverse events occurred. The G allele presented a trend for association with appetite reduction scores (P=0.05). A significant interaction between the G allele and treatment over time for appetite reduction scores was also observed (P=0.03). The G allele carriers presented a higher risk for appetite reduction worsening when compared with T allele homozygotes (odds ratio=3.47, P=0.01). The present results suggest an influence of carboxylesterase 1 -75 T>G polymorphism on the worsening of appetite reduction with MPH treatment in youths with ADHD.

Raw milk and colostrum can harbor dangerous micro-organisms that can pose serious health risks for animals and humans. According to the USDA, more than 58% of calves in the United States are fed unpasteurized milk. The aim of this study was to evaluate the effect of UV light on reduction of bacteria in milk and colostrum, and on colostrum IgG. A pilot-scale UV light continuous (UVC) flow-through unit (45 J/cm2) was used to treat milk and colostrum. Colostrum and sterile whole milk were inoculated with Listeria innocua, Mycobacterium smegmatis, Salmonella serovar Typhimurium, Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, and Acinetobacter baumannii before being treated with UVC. During UVC treatment, samples were collected at 5 time points and bacteria were enumerated using selective media. The effect of UVC on IgG was evaluated using raw colostrum from a nearby dairy farm without the addition of bacteria. For each colostrum batch, samples were collected at several different time points and IgG was measured using ELISA. The UVC treatment of milk resulted in a significant final count (log cfu/mL) reduction of Listeria monocytogenes (3.2 ± 0.3 log cfu/mL reduction), Salmonella spp. (3.7 ± 0.2 log cfu/mL reduction), Escherichia coli (2.8 ± 0.2 log cfu/mL reduction), Staph. aureus (3.4 ± 0.3 log cfu/mL reduction), Streptococcus spp. (3.4 ± 0.4 log cfu/mL reduction), and A. baumannii (2.8 ± 0.2 log cfu/mL reduction). The UVC treatment of milk did not result in a significant final count (log cfu/mL) reduction for M. smegmatis (1.8 ± 0.5 log cfu/mL reduction). The UVC treatment of colostrum was significantly associated with a final reduction of bacterial count (log cfu/mL) of Listeria spp. (1.4 ± 0.3 log cfu/mL reduction), Salmonella spp. (1.0 ± 0.2 log cfu/mL reduction), and Acinetobacter spp. (1.1 ± 0.3 log cfu/mL reduction), but not of E. coli (0.5 ± 0.3 log cfu/mL reduction), Strep. agalactiae (0.8 ± 0.2 log cfu/mL reduction), and Staph. aureus (0.4 ± 0.2 log cfu/mL reduction). The UVC treatment of colostrum significantly decreased the IgG concentration, with an observed final mean IgG reduction of approximately 50%. Development of new methods to reduce bacterial contaminants in colostrum must take into consideration the barriers imposed by its opacity and organic components, and account for the incidental damage to IgG caused by manipulating colostrum.

To evaluate the efficacy and safety of inhaled antibiotics for the treatment of non-cystic fibrosis bronchiectasis (NCFB). Pubmed, Cochrane library, Embase, Elsevier, OVID, Springerlink, Web of knowledge and NEJM were searched for randomized controlled trials (RCTs) on inhaled antibiotics in treatment of NCFB from inception until April 2015. Meta-analysis was conducted to assess the efficacy and safety of inhaled antibiotics in the treatment of NCFB. Twelve RCTs involving 1154 participants were included. They showed that inhaled antibiotics were more effective in reduction of sputum bacterial density, eradication of P. aeruginosa, prolonged time to exacerbation and reduction of new pathogens emergence with no significant difference in adverse events compared with control groups. However, we did not find significant benefits of inhaled antibiotics in reducing the risk of acute exacerbation, improving health-related quality of life and reduction of P. aeruginosa resistance. Moreover, inhaled antibiotics exerted a statistically significant reduction in FEV1%. Inhaled antibiotics may be an alternative pathway to inhibit airway inflammation with no more adverse events in patients with NCFB.

The psychoactive indole alkaloid ibogaine has been associated with encouraging treatment outcomes for opioid dependence. The legal status of ibogaine in New Zealand provides a unique opportunity to evaluate durability of treatment outcomes. To examine longitudinal treatment effects over a 12-month period among individuals receiving legal ibogaine treatment for opioid dependence. This observational study measured addiction severity as the primary outcome in 14 participants (50% female) over 12 months post-treatment using the Addiction Severity Index-Lite (ASI-Lite) following a single ibogaine treatment by either of two treatment providers. Secondary effects on depression were assessed via the Beck Depression Inventory-II (BDI-II). The Subjective Opioid Withdrawal Scale (SOWS) was collected before and immediately after treatment to measure opioid withdrawal symptoms. Nonparametric comparisons via Friedman Test between baseline and 12-month follow-up for participants completing all interviews (n = 8) showed a significant reduction for the ASI-Lite drug use (p = 0.002) composite score. Reductions in BDI-II scores from baseline to 12-month follow-up were also significant (p < 0.001). Significant reductions in SOWS scores for all participants (n = 14) were also observed acutely after treatment (p = 0.015). Patients with partial data (n = 4) also showed reductions in ASI-Lite drug use scores and family/social status problems. One patient enrolled in the study died during treatment. A single ibogaine treatment reduced opioid withdrawal symptoms and achieved opioid cessation or sustained reduced use in dependent individuals as measured over 12 months. Ibogaine's legal availability in New Zealand may offer improved outcomes where legislation supports treatment providers to work closely with other health professionals.

Reversal of left ventricular hypertrophy (LVH) in hypertensive patients appears to be a desirable goal to the reduction cardiac risk. The Renin-Angiotensin System (RAS) seems to play a major role in the establishment and maintenance of LVH through the activated systemic RAS and the Intracardiac Angiotensin System (IAS). We focused on the effects of a three-year treatment with losartan supplement in hypertensive patients with LVH not responding to eight years of an effective previous antihypertensive pharmacological treatment. Two groups of 28 sex-, age- and therapy-matched subjects with essential hypertension and LVH were taken into consideration. The two groups were in effective pharmacological treatment (BP < 140/90) for eight years previous to their enrollment. Patients of Group A were treated for three years with a losartan (100 mg/die) on-top treatment, whereas patients of Group B continued the follow-up of the previous conventional therapy. Both groups were submitted to an echocardiographic follow-up. Group A, showed a significant reduction of the mean LVH since the first step at six months with a further significant trend during the whole period (variance analysis: p < 0.001). Group B showed a non-significant trend toward LVH reduction during the three-year follow-up. No significant further reduction of systolic or diastolic blood pressure values was observed in both groups. The effects of losartan in hypertensive and hypertrophic patients are in agreement with the results of LIFE Trial. However, the reduction of left ventricular hypertrophy in our patients seems to be related to changes inducted by losartan on the IAS, since no further hemodynamic effects were observed. Losartan induced both a significant reduction of LVH and an improvement of LV diastolic function with a subsequent expected beneficial shift on the prognosis.

This study investigated (1) the susceptibility of Bacillus anthracis (Ames strain), Bacillus subtilis (ATCC 19659), and Clostridium sporogenes (ATCC 3584) spores to commercially available peracetic acid (PAA)- and glutaraldehyde (GA)-based disinfectants, (2) the effects that heat-shocking spores after treatment with these disinfectants has on spore recovery, and (3) the timing of heat-shocking after disinfectant treatment that promotes the optimal recovery of spores deposited on carriers. Suspension tests were used to obtain inactivation kinetics for the disinfectants against three spore types. The effects of heat-shocking spores after disinfectant treatment were also determined. Generalized linear mixed models were used to estimate 6-log reduction times for each spore type, disinfectant, and heat treatment combination. Reduction times were compared statistically using the delta method. Carrier tests were performed according to AOAC Official Method 966.04 and a modified version that employed immediate heat-shocking after disinfectant treatment. Carrier test results were analyzed using Fisher's exact test. PAA-based disinfectants had significantly shorter 6-log reduction times than the GA-based disinfectant. Heat-shocking B. anthracis spores after PAA treatment resulted in significantly shorter 6-log reduction times. Conversely, heat-shocking B. subtilis spores after PAA treatment resulted in significantly longer 6-log reduction times. Significant interactions were also observed between spore type, disinfectant, and heat treatment combinations. Immediately heat-shocking spore carriers after disinfectant treatment produced greater spore recovery. Sporicidal activities of disinfectants were not consistent across spore species. The effects of heat-shocking spores after disinfectant treatment were dependent on both disinfectant and spore species. Caution must be used when extrapolating sporicidal data of disinfectants from one spore species to another. Heat-shocking provides a more accurate picture of spore survival for only some disinfectant/spore combinations. Collaborative studies should be conducted to further examine a revision of AOAC Official Method 966.04 relative to heat-shocking. © 2015 The Authors.

Three insecticide mixtures that contain two classes of insecticides (pyrethroid and neonicotinoid) were recently developed to control bed bugs. We evaluated three integrated bed bug management strategies in apartments, each using the same non-chemical control methods and one of the three insecticide mixture products: Tandem (lambda-cyhalothrin + thiamethoxam), Temprid SC (beta-cyfluthrin + imidacloprid), and Transport Mikron (bifenthrin + acetamiprid). No insecticides were applied in the Control apartments. In all apartments, we installed vinyl mattress encasements (if not already present) and applied steam to beds and other infested upholstered furniture. Insecticide sprays were applied in the three treatments. Each treatment and the Control included 8-10 occupied apartments. Re-treatment was conducted during biweekly inspections if necessary. After eight weeks, the mean (± SEM) bed bug count reduction in the Tandem, Temprid SC, Transport Mikron, and Control was 89 ± 9, 87 ± 6, 98 ± 1, and 23 ± 54%, respectively. Only Tandem and Transport Mikron treatments resulted in significantly higher population reduction than the Control at eight weeks. There were no significant differences in mean percent reduction among the three treatments (Tandem, Temprid SC, Transport Mikron) at eight weeks. Tandem spray caused significantly faster bed bug reduction than Temprid SC spray and Transport Mikron spray.

The aim of this study was to compare the effectiveness of prophylactic single fixed dose of pegfilgrastim and daily administration of filgrastim on febrile neutropenia (FN), severe neutropenia, treatment delay, and dose reduction in patients with breast cancer receiving dose-dense adjuvant chemotherapy. A retrospective cohort study with 1058 breast cancer patients matched by age and chemotherapy was conducted. The primary endpoints were FN, severe (grade 3, 4) neutropenia, dose reduction (>10 % reduction of the dose planned), and treatment delay (dose given more than 2 days later). Eighteen episodes of FN (3.4%) in the filgrastim group and 23 (4.3%) in the pegfilgrastim group (p = 0.500) were recorded. More than half of the total episodes (27/41) occurred during the first 4 cycles of treatment. Patients who received filgrastim were almost three times more likely to experience a severe neutropenia episode and were significantly more likely to experience a dose reduction (18.5%) compared to those who received pegfilgrastim (10.8%) (p < 0.001). The percentage of patients, who received their planned dose on time, was significantly lower in patients receiving filgrastim (58%) compared to those receiving pegfilgrastim (72.4%, p < 0.001). No significant difference was detected on FN rate between daily administration of filgrastim and single administration of pegfilgrastim. However, patients receiving pegfilgrastim had a significantly lower rate of severe neutropenia, as well as dose reduction and treatment delay, thus, achieving a higher dose density.

An important consideration in the environmental release of a genetically engineered microorganism (GEM) is the capability for reduction or elimination of GEM populations once their function is completed or if adverse environmental effects are observed. The decontamination treatments of burning and biocide application, alone and in combination with tilling, were evaluated for their ability to reduce populations of bacteria released on the phylloplane. Field plots of bush beans sprayed with the bacterium Erwinia herbicola, received the following treatments: (1) control, (2) control + till, (3) burn, (4) burn + till, (5) Kocide (cupric hydroxide), (6) Kocide + till, (7) Agri-strepmore » (streptomycin sulfate), and (8) Agri-strept + till. Leaves and soil from the plots were sampled -1, 1, 5, 8, 12, 15, 19, and 27 days after application of the decontamination treatments. Burning produced a significant and persistent reduction in the number of bacteria whereas tilling, alone or in combination with the biocide treatments, stimulated a significant and persistent reduction in the number of bacteria, whereas tilling, alone or in combination with the biocide treatments, stimulated a significant increase in bacterial populations that persisted for several weeks.« less

The aim of this study was to investigate the effect of sodium nitrite and high hydrostatic pressure on the color, water holding capacity (WHC) and texture characteristics of frankfurter. Three hundred, 450 and 600 MPa (5 minutes; 20 °C) and 50, 75, 100 and 125 ppm (calculated on weight of meat) sodium nitrite were applied. Parameters were measured right after the pressure treatment. Data were evaluated with two-way analysis of variance (p 0.05) with pressure levels and sodium nitrite amounts as factors. Nitrite reduction significantly increased lightness (L*) and resulted in decreased redness (a*) value. The pressure treatments decreased the lightness at all nitrite concentrations and did not significantly affect the red color of frankfurters. Fifty and 75 ppm nitrite and pressurization at 300 or 450 MPa improved the water holding property of frankfurter. The pressure treatment did not significantly affect the WHC but changing the nitrite amount had significant effect on it. Interactive effect occurred between pressure levels and nitrite concentrations for hardness. The pressure treatment increased and the nitrite reduction decreased hardness. Significant changes were found in cohesiveness at 450 and 600 MPa in frankfurters containing 50 and 75 ppm nitrite: pressure treatment at higher levels and nitrite reduction decreased the value of cohesiveness.

Cosmetic products are not tested with the same rigour as medical treatments, but recent high-quality studies have shown significant reductions in changes of skin ageing with use of cosmetic antiageing products. To test whether a cosmetic 'anti-spot' two-step treatment containing a complex of seaweed-derived oligosaccharide and zinc would produce a significant improvement in mild acne. A double-blind, vehicle-controlled trial of this treatment was performed for 8 weeks on 60 age-matched participants with mild acne. They were divided into two groups: 30 participants were treated with vehicle control and 30 with the active treatment containing a seaweed-derived oligosaccharide complexed with 0.1% zinc pyrrolidone. After 8 weeks, both groups had a reduction in comedones, papules and pustules, and this was significantly greater in the active than control group at 2, 4 and 8 weeks. Cosmetic products may offer some benefit for mild acne and still meet the requirements of the European Cosmetic Directive. In particular, the seaweed-derived oligosaccharide complexed with 0.1% zinc pyrrolidone used in this study produced a significant reduction in acne vs. a control treatment. Cosmetic companies should conduct blinded controlled trials of their product's efficacy and publish the results. © The Author(s). CED © 2012 British Association of Dermatologists.

The objective of the present study was to investigate the effectiveness and safety of ultrasound-guided microwave ablation in the treatment of benign thyroid nodules. A total of 474 benign thyroid nodules in 435 patients who underwent ultrasound-guided microwave ablation from September 2012 to August 2015 were included. Nodule volume and thyroid function were measured before treatment and at 1, 3, 6, and 12 months and subsequently after every 6 months. The nodule volume reduction rate and changes of thyroid function were evaluated. The volume of all thyroid nodules significantly decreased after ultrasound-guided microwave ablation. The average volume was 13.07 ± 0.95 ml before treatment, and 1.14 ± 0.26 ml at 12-months follow-up. The mean volume reduction rate was 90% and the final volume reduction rate was 94%. The volume reduction rate of mainly cystic nodules was significantly higher than that of simple solid and mainly solid nodules (all P < 0.05). The pretreatment volume of nodules was positively correlated with the final volume reduction rate at final follow-up (P = 0.004). No serious complications were observed after treatment. In conclusion, ultrasound-guided microwave ablation is an effective and safe technique for treatment of benign thyroid nodules, and has the potential for clinical applications. Impact statement Ultrasound-guided MWA is an effective and safe technique for the treatment of benign thyroid nodules. It can significantly reduce the nodule volume, improve the patients’ clinical symptoms, has less complication, guarantees quick recovery, meets patients' aesthetic needs, and shows less interference on the physiological and psychological aspects of the body. MWA should be a good complement to traditional open surgery and has potentials in clinical applications. PMID:28847173

Although self-harm has been observed among patients with eating disorders, the effects of such tendencies on treatment outcomes are unclear. The current study employed structural equation modeling to (a) evaluate the relationship between self-harm and changes in body dissatisfaction and drive for thinness in a large sample of patients (n = 2061) who underwent inpatient treatment, and (b) to examine whether the relationship between self-harm and changes in body dissatisfaction and drive for thinness during inpatient treatment remains significant when controlling for change in negative affect during treatment. Results revealed that patients with a history of self-harm reported significantly less reduction in body dissatisfaction and drive for thinness following treatment. Patients experiencing less change in negative affect also reported significantly less reduction in body dissatisfaction and drive for thinness after discharge from treatment. However, the association between history of self-harm and reduction in body dissatisfaction and drive for thinness after treatment became non-significant when controlling for change in negative affect. This pattern of findings was also replicated among patients with a primary diagnosis of anorexia nervosa (n = 845), bulimia nervosa (n = 565), and eating disorder not otherwise specified (n = 651). The implications of these findings for delineating the specific role of self-harm in the nature and treatment of eating disorders are discussed. Copyright © 2015 Elsevier Ltd. All rights reserved.

Throughfall reduction and nutrient availability effects on carbon balance in loblolly pine plantations in the southeastern United States

Planted loblolly pine covers over 11 million hectares in the southeastern United States. Occurring across a range of climatic conditions, these pine plantations are critical for the regional economy and offset a significant fraction of anthropogenic CO2 emissions. Loblolly pine productivity has been enhanced through genetic improvement and intensive silviculture. However, climate projections forecast higher air temperature and more variable precipitation patterns for the region. A critical question is how silvicultural practices will interact with projected climate change to affect loblolly pine carbon balance. A fertilization by throughfall reduction experiment was established in the spring of 2012 at four loblolly pine plantations at the margins of the natural range of the specie (Florida FL, Georgia GA, Oklahoma OK and Virginia VA). Net primary productivity (NPP) was estimated from repeated tree inventories and net ecosystem productivity (NEP) as the difference between NPP and heterotrophic respiration (RH). Soil respiration (RS) and RH were measured simultaneously several times during the experiment. Throughfall reduction significantly decreased surface soil water content at all sites. After four years of treatment, fertilization increased NPP at all sites and throughfall reduction had a negative effect on NPP at the GA and OK sites. The combination fertilization x throughfall reduction did not have a significant effect on NPP. RS and RH were, in general negatively affected by fertilization and throughfall reduction with differential responses between sites, leading to significant NEP increases under fertilization, while throughfall reduction increased NEP at FL and VA due to no effect on NPP and negative effect on RS. Fertilization offset the negative effect of throughfall reduction on NEP in the fertilization x throughfall reduction treatment. All sites were significant carbon sinks, accumulating from 3.5 to 24 Mg C ha-1 in a 3 year period under a range of climatic conditions, age and treatments.

Raw milk and colostrum can harbor dangerous microorganisms that can pose serious health risks for animals and humans. According to the USDA, more than 58% of calves in the United States are fed unpasteurized milk. The aim of this study was to evaluate the effect of UV light on reduction of bacteria in milk and colostrum, and on colostrum IgG. A pilot-scale UV light continuous (UVC) flow-through unit (45 J/cm(2)) was used to treat milk and colostrum. Colostrum and sterile whole milk were inoculated with Listeria innocua, Mycobacterium smegmatis, Salmonella serovar Typhimurium, Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, and Acinetobacter baumannii before being treated with UVC. During UVC treatment, samples were collected at 5 time points and bacteria were enumerated using selective media. The effect of UVC on IgG was evaluated using raw colostrum from a nearby dairy farm without the addition of bacteria. For each colostrum batch, samples were collected at several different time points and IgG was measured using ELISA. The UVC treatment of milk resulted in a significant final count (log cfu/mL) reduction of Listeria monocytogenes (3.2 ± 0.3 log cfu/mL reduction), Salmonella spp. (3.7 ± 0.2 log cfu/mL reduction), Escherichia coli (2.8 ± 0.2 log cfu/mL reduction), Staph. aureus (3.4 ± 0.3 log cfu/mL reduction), Streptococcus spp. (3.4 ± 0.4 log cfu/mL reduction), and A. baumannii (2.8 ± 0.2 log cfu/mL reduction). The UVC treatment of milk did not result in a significant final count (log cfu/mL) reduction for M. smegmatis (1.8 ± 0.5 log cfu/mL reduction). The UVC treatment of colostrum was significantly associated with a final reduction of bacterial count (log cfu/mL) of Listeria spp. (1.4 ± 0.3 log cfu/mL reduction), Salmonella spp. (1.0 ± 0.2 log cfu/mL reduction), and Acinetobacter spp. (1.1 ± 0.3 log cfu/mL reduction), but not of E. coli (0.5 ± 0.3 log cfu/mL reduction), Strep. agalactiae (0.8 ± 0.2 log cfu/mL reduction), and Staph. aureus (0.4 ± 0.2 log cfu/mL reduction). The UVC treatment of colostrum significantly decreased the IgG concentration, with an observed final mean IgG reduction of approximately 50%. Development of new methods to reduce bacterial contaminants in colostrum must take into consideration the barriers imposed by its opacity and organic components, and account for the incidental damage to IgG caused by manipulating colostrum.

Sound data which were obtained during tests of a 50.8 cm diameter, subsonic tip speed, low pressure ratio fan were analyzed. The test matrix was divided into two major investigations: (1) source noise reduction techniques; and (2) aft duct noise reduction with acoustic treatment. Source noise reduction techniques were investigated which include minimizing second harmonic noise by varying vane/blade ratio, variation in spacing, and lowering the Mach number through the vane row to lower fan broadband noise. Treatment in the aft duct which includes flow noise effects, faceplate porosity, rotor OGV treatment, slant cell treatment, and splitter simulation with variable depth on the outer wall and constant thickness treatment on the inner wall was investigated. Variable boundary conditions such as variation in treatment panel thickness and orientation, and mixed porosity combined with variable thickness were examined. Significant results are reported.

The purpose of this study was to investigate the short-term effect of topical antiglaucoma medication on tear-film stability, tear secretion, and corneal sensitivity in healthy subjects. In this prospective, double-blind crossover trial, break-up time and basal secretion (Jones test) were measured 60 minutes before, and 30, 60, and 90 minutes after topical antiglaucoma drop application in 30 healthy subjects. Corneal sensitivity was measured 60 minutes before, and five, 10, and 15 minutes after drop application using a Cochet-Bonnet esthesiometer. Reduction of break-up time in the latanoprost group was -23.8% after 30 minutes (P = 0.21), -26.7% after 60 minutes (P = 0.03) and -51.4% after 90 minutes (P ≤ 0.003), which was statistically significant. Reduction of break-up time in all other treatment groups was not statistically significant. The Jones test revealed a significant reduction of basal secretion after application of brimonidine (-17.8%, P = 0.002; -22.5%, P < 0.001; -30.5%, P < 0.001), followed by apraclonidine (-10%, P = 0.06; -20.1%, P = 0.02; -22.1%, P = 0.002), latanoprost (-2.4%, P = 0.64; -18.6%, P = 0.001; -20.1%, P = 0.001) and dorzolamide (-0.5%, P = 0.9; 14.3%, P = 0.018; -17.3%, P = 0.004) at 30, 60, and 90 minutes after drop application. Reduction of basal secretion in all other treatment groups was not statistically significant. Latanoprost showed the most statistically significant reduction in break-up time, and brimonidine showed the most significant reduction in basal secretion of all the glaucoma medications used in this study. In conclusion, our data may be helpful for treatment decisions in glaucoma patients who also suffer from ocular surface problems.

Background We previously demonstrated the therapeutic benefits of pentosan polysulfate (PPS) in a rat model of mucopolysaccharidosis (MPS) type VI. Reduction of inflammation, reduction of glycosaminoglycan (GAG) storage, and improvement in the skeletal phenotype were shown. Herein, we evaluate the long-term safety and therapeutic effects of PPS in a large animal model of a different MPS type, MPS I dogs. We focused on the arterial phenotype since this is one of the most consistent and clinically significant features of the model. Methodology/Principal Findings MPS I dogs were treated with daily oral or biweekly subcutaneous (subQ) PPS at a human equivalent dose of 1.6 mg/kg for 17 and 12 months, respectively. Safety parameters were assessed at 6 months and at the end of the study. Following treatment, cytokine and GAG levels were determined in fluids and tissues. Assessments of the aorta and carotid arteries also were performed. No drug-related increases in liver enzymes, coagulation factors, or other adverse effects were observed. Significantly reduced IL-8 and TNF-alpha were found in urine and cerebrospinal fluid (CSF). GAG reduction was observed in urine and tissues. Increases in the luminal openings and reduction of the intimal media thickening occurred in the carotids and aortas of PPS-treated animals, along with a reduction of storage vacuoles. These results were correlated with a reduction of GAG storage, reduction of clusterin 1 staining, and improved elastin integrity. No significant changes in the spines of the treated animals were observed. Conclusions PPS treatment led to reductions of pro-inflammatory cytokines and GAG storage in urine and tissues of MPS I dogs, which were most evident after subQ administration. SubQ administration also led to significant cytokine reductions in the CSF. Both treatment groups exhibited markedly reduced carotid and aortic inflammation, increased vessel integrity, and improved histopathology. We conclude that PPS may be a safe and useful therapy for MPS I, either as an adjunct or as a stand-alone treatment that reduces inflammation and GAG storage. PMID:27064989

Psoriasis is a chronic condition that may require long-term treatment for disease control. This analysis utilizes data from the Australasian Psoriasis Registry with particular attention to the impact of biologic therapy on DLQI, and the differences between the biologics in terms of DLQI score change. A retrospective review of patients enrolled in the Australasian Psoriasis Registry from April 2008 to August 2016 was conducted. All subjects from the registry that had DLQI and Psoriasis Assessment Severity Index (PASI) scores recorded at a baseline time point of treatment commencement, in addition to week 12 and 24 post commencement were included in the study. A window of ±3 weeks was permitted at these time points. Multivariate linear regression analysis was undertaken to identify significant predictors associated with change in DLQI. Significant predictors of reduction in DLQI and PASI score from baseline to week 24 include use of adalimumab, infliximab, secukinumab and ustekinumab. Other therapies, including etanercept and oral systemic agents did not show significant change. Each class of biologic showed significant reductions in DLQI score, with IL-12/23 blockade showing the greatest reduction. Significant predictors of lack of reduction in DLQI score include a baseline PASI score <16, and history of diabetes, alcoholism or uveitis. Patients with moderate to severe chronic plaque psoriasis who are treated with biologics show the greatest reduction in DLQI score, compared with other treatments. Australian dermatologists are prescribing biologics when patients qualify for them in keeping with current guidelines.

Aims One of the primary determinants of blood flow in regional vascular beds is perfusion pressure. Our aim was to investigate if reduction in blood pressure during the treatment of decompensated heart failure would be associated with worsening renal function (WRF). Our secondary aim was to evaluate the prognostic significance of this potentially treatment-induced form of WRF. Methods and results Subjects included in the Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness (ESCAPE) trial limited data were studied (386 patients). Reduction in systolic blood pressure (SBP) was greater in patients experiencing WRF (−10.3 ± 18.5 vs. −2.8 ± 16.0 mmHg, P < 0.001) with larger reductions associated with greater odds for WRF (odds ratio = 1.3 per 10 mmHg reduction, P < 0.001). Systolic blood pressure reduction (relative change > median) was associated with greater doses of in-hospital oral vasodilators (P ≤ 0.017), thiazide diuretic use (P = 0.035), and greater weight reduction (P = 0.023). In patients with SBP-reduction, WRF was not associated with worsened survival [adjusted hazard ratio (HR) = 0.76, P = 0.58]. However, in patients without SBP-reduction, WRF was strongly associated with increased mortality (adjusted HR = 5.3, P < 0.001, P interaction = 0.001). Conclusion During the treatment of decompensated heart failure, significant blood pressure reduction is strongly associated with WRF. However, WRF that occurs in the setting of SBP-reduction is not associated with an adverse prognosis, whereas WRF in the absence of this provocation is strongly associated with increased mortality. These data suggest that WRF may represent the final common pathway of several mechanistically distinct processes, each with potentially different prognostic implications. PMID:21693504

A study was done to determine the efficacy of aqueous ozone treatment in killing Listeria monocytogenes on inoculated alfalfa seeds and sprouts. Reductions in populations of naturally occurring aerobic microorganisms on sprouts and changes in the sensory quality of sprouts were also determined. The treatment (10 or 20 min) of seeds in water (4 degrees C) containing an initial concentration of 21.8 +/- 0.1 microg/ml of ozone failed to cause a significant (P < or = 0.05) reduction in populations of L. monocytogenes. The continuous sparging of seeds with ozonated water (initial ozone concentration of 21.3 +/- 0.2 microg/ml) for 20 min significantly reduced the population by 1.48 log10 CFU/g. The treatment (2 min) of inoculated alfalfa sprouts with water containing 5.0 +/- 0.5, 9.0 +/- 0.5, or 23.2 +/- 1.6 microg/ml of ozone resulted in significant (P < or = 0.05) reductions of 0.78, 0.81, and 0.91 log10 CFU/g, respectively, compared to populations detected on sprouts treated with water. Treatments (2 min) with up to 23.3 +/- 1.6 microg/ml of ozone did not significantly (P > 0.05) reduce populations of aerobic naturally occurring microorganisms. The continuous sparging of sprouts with ozonated water for 5 to 20 min caused significant reductions in L. monocytogenes and natural microbiota compared to soaking in water (control) but did not enhance the lethality compared to the sprouts not treated with continuous sparging. The treatment of sprouts with ozonated water (20.0 microg/ml) for 5 or 10 min caused a significant deterioration in the sensory quality during subsequent storage at 4 degrees C for 7 to 11 days. Scanning electron microscopy of uninoculated alfalfa seeds and sprouts showed physical damage, fungal and bacterial growth, and biofilm formation that provide evidence of factors contributing to the difficulty of killing microorganisms by treatment with ozone and other sanitizers.

Effects of greening and community reuse of vacant lots on crime

The Youngstown Neighborhood Development Corporation initiated a ‘Lots of Green’ programme to reuse vacant land in 2010. We performed a difference-in-differences analysis of the effects of this programme on crime in and around newly treated lots, in comparison to crimes in and around randomly selected and matched, untreated vacant lot controls. The effects of two types of vacant lot treatments on crime were tested: a cleaning and greening ‘stabilisation’ treatment and a ‘community reuse’ treatment mostly involving community gardens. The combined effects of both types of vacant lot treatments were also tested. After adjustment for various sociodemographic factors, linear and Poisson regression models demonstrated statistically significant reductions in all crime classes for at least one lot treatment type. Regression models adjusted for spatial autocorrelation found the most consistent significant reductions in burglaries around stabilisation lots, and in assaults around community reuse lots. Spill-over crime reduction effects were found in contiguous areas around newly treated lots. Significant increases in motor vehicle thefts around both types of lots were also found after they had been greened. Community-initiated vacant lot greening may have a greater impact on reducing more serious, violent crimes. PMID:28529389

The purpose of this study was to evaluate the efficacy and tolerability of aluminium chloride gel for treatment of axillary hyperhidrosis. A total of 20 patients aged 22-38 (mean age: 26.9+/-4.3) with idiopathic axillary hyperhidrosis were included and treated with an antiperspirant (Sweat-off, Sweat-off GmbH, Hügelsheim). Study duration was 42 days. Treatment efficacy was evaluated clinically, as well as by starch-iodine test, gravimetric analysis and evaluation of the skin surface pH. After treatment there was a significant clinical improvement accompanied by significant qualitative and quantitative reduction of sweat as well as a significant reduction of skin surface pH. Except for slight skin irritation in 6 patients, there were no other side effects. Patient satisfaction improved markedly during the study. Treatment of axillary hyperhidrosis with aluminium chloride is an effective, safe and inexpensive treatment modality.

Reduction of assaultive behavior following anger treatment of forensic hospital patients with intellectual disabilities.

PubMed

Novaco, Raymond W; Taylor, John L

2015-02-01

Anger is related to violence prior to hospitalization, during hospitalization, and after discharge. Meta-analyses have established treatment efficacy in reducing anger, but few studies have addressed whether reduced anger leads to lowered aggressive behavior. This study concerns individually-delivered anger treatment, specialized for offenders with intellectual disabilities, delivered twice weekly for 18 sessions to 50 forensic hospital patients. Assessments involved patient self-report of anger, staff ratings of anger and aggression, and case records of assaultive incidents. Physical assault data were obtained from records 12 months pre-treatment and 12 months post-treatment. Significant reductions in assaults following treatment were found by GEE analyses, controlling for age, gender, length of stay, IQ, and pre-hospital violence. Following treatment, physical attacks reduced by more than half, dropping from approximately 3.5 attacks per patient 6 months prior to treatment, versus approximately 1 attack per patient in the 6-12 month interval post-treatment. In hierarchical regressions, controlling for IQ, reduction in physical assaults was associated with pre-to post-treatment change in anger level. These findings buttress the efficacy of anger treatment for patients having histories of violence and have significance for patient mental health, hospital staff well-being, therapeutic milieu, hospital management, and service delivery costs.

To determine if the use of hydrocortisone cream decreases perineal pain in the immediate postpartum period. This was a randomized controlled trial (RCT), crossover study design, with each participant serving as their own control. Participants received three different methods for perineal pain management at three sequential perineal pain treatments after birth: two topical creams (corticosteroid; placebo) and a control treatment (no cream application). Treatment order was randomly assigned, with participants and investigators blinded to cream type. The primary dependent variable was the change in perineal pain levels (posttest minus pretest pain levels) immediately before and 30 to 60 minutes after perineal pain treatments. Data were analyzed with analysis of variance, with p < 0.05 considered significant. A total of 27 participants completed all three perineal pain treatments over a 12-hour period. A reduction in pain was found after application of both the topical creams, with average perineal pain change scores of -4.8 ± 8.4 mm after treatment with hydrocortisone cream (N = 27) and -6.7 ± 13.0 mm after treatment with the placebo cream (N = 27). Changes in pain scores with no cream application were 1.2 ± 10.5 mm (N = 27). Analysis of variance found a significant difference between treatment groups (F2,89 = 3.6, p = 0.03), with both cream treatments having significantly better pain reduction than the control, no cream treatment (hydrocortisone vs. no cream, p = 0.04; placebo cream vs. no cream, p = 0.01). There were no differences in perineal pain reduction between the two cream treatments (p = .54). This RCT found that the application of either hydrocortisone cream or placebo cream provided significantly better pain relief than no cream application.

Modification of elevated positive expectations of alcohol consumption (alcohol outcome expectancies; AOEs) is a key feature of Cognitive Behaviour Therapy (CBT) approaches to Alcohol Use Disorders (AUDs). Despite extensive research supporting the efficacy of CBT for AUD, few studies have examined AOE change. This study aimed to assess AOE change following completion of CBT for AUD and its association with drinking behaviour. One-hundred and seventy-five patients who completed a 12-week CBT program for AUD were administered the Drinking Expectancy Questionnaire (DEQ) at pre-treatment assessment and upon completion of treatment. Abstinence was achieved by 108 (61.7%) of completing patients. For patients who lapsed, the mean proportion of abstinent days was 93%. DEQ scales assessing expectations of positive alcohol effects on tension reduction, assertiveness, and cognitive enhancement were significantly lower post-treatment (p<0.001). Expectations of negative effects on mood were higher post-treatment (p<0.001). The largest AOE change occurred on the tension reduction scale. Greater percentage of abstinent days over treatment was associated with lower pre-and post-treatment tension reduction expectancy scores (p<0.05). Drinking during treatment was associated with smaller changes in expectations of negative effects of alcohol on mood (p<0.05). Individuals who completed CBT treatment for AUD showed significant AOE change. Tension reduction and affective change expectancies may be particularly important for abstinence and useful markers of lapse risk. Copyright © 2018 Elsevier Ltd. All rights reserved.

The authors present the Moving Bed Biofilm Reactor (MBBR) model with a quasi-continuous flow for small water reservoir restoration, characterized by high concentrations of organic pollutants. To determine the efficiency of wastewater treatment the laboratory analysis of physic-chemical parameters were conducted for the model on a semi-technical scale of 1:3. Wastewater treatment process was carried out in 24 h for 1 m3 for raw sewage. The startup period was 2 weeks for all biofilters (biological beds). Approximately 50% reduction in COD and BOD5 was obtained on average for the studied bioreactors. Significant improvements were achieved in theclarity of the treated wastewater, with the reduction of suspension by 60%. The oxygen profile has improved significantly in 7 to 9 hours of the process, and a diametric reduction in the oxidative reduction potential was recorded. A preliminary model of biological treatment effectiveness was determined based on the conducted studies. In final stages, the operation mode was set in real conditions of polluted water reservoirs.

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

To determine the safety and efficacy of a 50 ns Q switched Nd YAG laser vs. a 5 ns Q switched Nd YAG laser for clearance of melasma. To compare subject satisfaction, efficacy, and comfort level between the two lasers. This is a prospective, randomized split face clinical study. The study was approved by the Scripps IRB. Ten healthy female subjects with moderate to severe melasma were enrolled. Each subject had three laser treatments one month apart. Patients were followed up approximately 1 month, 3 months, and 6 months after the final laser treatment. A treatment session consisted of a microdermabrasion, 1064 nm QS laser, and topicals. Subjects were asked to rate treatment pain based on a numerical scale range 0-10 (0 = no pain and 10 = worst pain). A melasma area and severity index (MASI) grading system was applied. Also, melanin measurements were acquired by a reflectance spectrophotometer. Side effects were documented during the study including post treatment erythema. Eight patients completed the study. Subjects showed improvement on both sides of the face. From baseline to 1 month post the final laser treatment, the average MASI scores showed a 16% reduction for the 50 ns QS 1064 nm laser vs. a 27% reduction for the 5 ns QS 1064 nm laser (both significant versus baseline pigment, P < 0.05). This difference in MASI scores between the two lasers was not statistically significant (P = 0.87930). Laser treatments displayed mild erythema that resolved after one day. The melanin meter measurements showed a reduction in pigment readings on both sides. Three months after the final treatment there was some relapse in the melasma, as the mean pigment reduction fell to 12% for the 50 ns laser and 11% for the 5 ns laser. By 3 months pigment reduction was not statistically significant for either laser, and no significant differences in pigment reduction were noted between the two pulse durations. There was a statistically significant difference (P < 0.05) in pain scores reported by the subjects (scale 0-10), the mean pain score for 50 ns QS 1064 nm laser was 1.2 and for the 5 ns QS 2.9 the score was 2.9. In this study, we showed that a combination of microdermabrasion, QS1064 nm laser, and topicals decreased the MASI and meter scores without clinically significant side effects. Moreover, the longer pulsed Q switched 1064 nm laser i.e. (50 ns) was associated with less pain than its shorter pulse width counterpart. © 2014 Wiley Periodicals, Inc.

Hepatitis E virus has been recognised as a food-borne virus hazard in pork products, due to its zoonotic properties. This risk can be reduced by adequate treatment of the food to inactivate food-borne viruses. We used a spectrum of viruses and bacteriophages to evaluate the effect of three food treatments: high pressure processing (HPP), lactic acid (LA) and intense light pulse (ILP) treatments. On swine liver at 400 MPa for 10 min, HPP gave log 10 reductions of ≥4.2, ≥5.0 and 3.4 for feline calicivirus (FCV) 2280, FCV wildtype (wt) and murine norovirus 1 (MNV 1), respectively. Escherichia coli coliphage ϕX174 displayed a lower reduction of 1.1, while Escherichia coli coliphage MS2 was unaffected. For ham at 600 MPa, the corresponding reductions were 4.1, 4.4, 2.9, 1.7 and 1.3 log 10 . LA treatment at 2.2 M gave log 10 reductions in the viral spectrum of 0.29-2.1 for swine liver and 0.87-3.1 for ham, with ϕX174 and MNV 1, respectively, as the most stable microorganisms. The ILP treatment gave log 10 reductions of 1.6-2.8 for swine liver, 0.97-2.2 for ham and 1.3-2.3 for sausage, at 15-60 J cm -2 , with MS2 as the most stable microorganism. The HPP treatment gave significantly (p < 0.05) greater virus reduction on swine liver than ham for the viruses at equivalent pressure/time combinations. For ILP treatment, reductions on swine liver were significantly (p < 0.05) greater than on ham for all microorganisms. The results presented here could be used in assessments of different strategies to protect consumers against virus contamination and in advice to food producers. Conservative model indicators for the pathogenic viruses could be suggested.

Low molecular weight, uncharged, halogenated disinfection byproducts (DBPs) are poorly removed by the reverse osmosis and advanced oxidation process treatment units often applied for further treatment of municipal wastewater for potable reuse. Granular activated carbon (GAC) treatment effectively sorbed 22 halogenated DBPs. Conversion of the GAC to a cathode within an electrolysis cell resulted in significant degradation of the 22 halogenated DBPs by reductive electrolysis at -1 V vs. Standard Hydrogen Electrode (SHE). The lowest removal efficiency over 6 h electrolysis was for trichloromethane (chloroform; 47%) but removal efficiencies were >90% for 13 of the 22 DBPs. In all cases, DBP degradation was higher than in electrolysis-free controls, and degradation was verified by the production of halides as reduction products. Activated carbons and charcoal were more effective than graphite for electrolysis, with graphite featuring poor sorption for the DBPs. A subset of halogenated DBPs (e.g., haloacetonitriles, chloropicrin) were degraded upon sorption to the GAC, even without electrolysis. Using chloropicrin as a model, experiments indicated that this loss was attributable to the partial reduction of sorbed chloropicrin from reducing equivalents in the GAC. Reducing equivalents depleted by these reactions could be restored when the GAC was treated by reductive electrolysis. GAC treatment of an advanced treatment train effluent for potable reuse effectively reduced the concentrations of chloroform, bromodichloromethane and dichloroacetonitrile measured in the column influent to below the method detection limits. Treatment of the GAC by reductive electrolysis at -1 V vs. SHE over 12 h resulted in significant degradation of the chloroform (63%), bromodichloromethane (96%) and dichloroacetonitrile (99%) accumulated on the GAC. The results suggest that DBPs in advanced treatment train effluents could be captured and degraded continuously by reductive electrolysis using a GAC-based cathode. Copyright © 2016 Elsevier Ltd.

We examined the effect of a 12-week family-based cognitive behavioural weight management programme developed for use in primary care settings. The sample consisted of 49 children with obesity (aged 7-13 years; mean ± SD: 10.68 ± 1.24). Families were randomly assigned to immediate start-up of treatment or to a 12-week waiting list condition. Outcome measures were body mass index standard deviation score (BMI SDS), self-esteem, symptoms of depression and blood parameters indicative of cardio-metabolic risk. Assessments were conducted at baseline, post-treatment, post-waiting list and 12 months after treatment termination. The mean reduction for the treatment group was -0.16 BMI SDS units compared with an increase of 0.04 units for the waiting list group (p = .001). For the entire sample, there was a significant post-treatment improvement on BMI SDS (p = .001), all self-esteem measures (p = .001-.041) and symptoms of depression (p = .004). The mean BMI SDS reduction was -0.18 units post-treatment, and it was maintained at 12-month follow-up. Significant reductions were found in blood lipid levels of total cholesterol (p = .03), LDL-cholesterol (p = .005) and HDL-cholesterol (p = .01) at 12-month follow-up. The favourable effect on most of the psychological measures waned from post-treatment to follow-up, but not approaching baseline levels. Boys demonstrated significantly greater reductions in BMI SDS than girls (p = .001), while baseline psychiatric co-morbidity did not influence BMI SDS outcome. The treatment shows significant and favourable effects on BMI SDS, self-esteem and symptoms of depression compared with a waiting list condition. © 2013 Asian Oceanian Association for the Study of Obesity .

To evaluate the effectiveness of antihypertensives in reducing neurocognitive outcomes in elderly patients. We conducted a systematic literature search of randomized trials in which hypertensive patients with a mean age ≥65 years received antihypertensive or control treatment. Outcomes were stroke, transient ischemic attack, cognitive decline and dementia. We included 14 trials for meta-analysis. Compared to placebo, antihypertensive treatment reduced the risk of stroke (RR: 0.67 [95% CI: 0.57-0.79]). Reduced risk was significant for transient ischemic attack, fatal stroke, nonfatal stroke and total stroke. There were insufficient data to compare individual agents. Antihypertensive treatment is associated with a significant reduction in stroke in elderly individuals. Reductions in dementia and cognitive decline were not significant; however, there was short follow-up. Comparative effectiveness evidence is limited.

Removing unwanted body hair is a growing trend in society today, and there are many laser-based devices for hair reduction. There are some limitations to those methods, including the lack of efficacy for lighter color hair. The objective was to quantify hair reduction in the axillae after treatment with a noninvasive microwave energy device. A prospective, multicenter study was performed at 3 private dermatology clinics. Fifty-six adult subjects seeking axillary hair reduction were enrolled and treated with the device in 1 or 2 treatment sessions 3 months apart at various energy levels, and followed for 12 months. The primary analysis was monitoring reduction of hair counts from baseline to follow-up visits. A subject assessment of overall satisfaction, odor ratings, and sweat reduction ratings was provided at follow-up visits. Fifty-six subjects received treatment, with an average total underarm hair reduction of approximately 70% for both light and dark hair. Percentage of patients with hair reduction of 30% or more was significantly higher than 50% at all follow-up visits. Half of treated subjects reported expected mild transient post-treatment effects such as localized edema, discomfort, and bruising. Other reported events were mild. This clinical study provides evidence for safe and permanent axillary hair reduction, showing stable average reduction that lasted through the year of follow-up. Most notably, the study has shown the treatment's efficacy for reduction of light-colored axillary hair.

To prevent adverse long-term effects, children who suffer from posttraumatic stress symptoms (PTSS) need treatment. Trauma-focused cognitive behavioral therapy (TF-CBT) is an established treatment for children with PTSS. However, alternatives are important for non-responders or if TF-CBT trained therapists are unavailable. Eye movement desensitization and reprocessing (EMDR) is a promising treatment for which sound comparative evidence is lacking. The current randomized controlled trial investigates the effectiveness and efficiency of both treatments. Forty-eight children (8-18 years) were randomly assigned to eight sessions of TF-CBT or EMDR. The primary outcome was PTSS as measured with the Clinician-Administered PTSD Scale for Children and Adolescents (CAPS-CA). Secondary outcomes included parental report of child PTSD diagnosis status and questionnaires on comorbid problems. The Children's Revised Impact of Event Scale was administered during the course of treatment. TF-CBT and EMDR showed large reductions from pre- to post-treatment on the CAPS-CA (-20.2; 95% CI -12.2 to -28.1 and -20.9; 95% CI -32.7 to -9.1). The difference in reduction was small and not statistically significant (mean difference of 0.69, 95% CI -13.4 to 14.8). Treatment duration was not significantly shorter for EMDR (p = 0.09). Mixed model analysis of monitored PTSS during treatment showed a significant effect for time (p < 0.001) but not for treatment (p = 0.44) or the interaction of time by treatment (p = 0.74). Parents of children treated with TF-CBT reported a significant reduction of comorbid depressive and hyperactive symptoms. TF-CBT and EMDR are effective and efficient in reducing PTSS in children.

Contamination of spices by pathogenic and/or spoilage bacteria can be deleterious to consumer's health and cause deterioration of foods, and inactivation of such bacteria is necessary for the food industry. The present study examined the effect of gaseous acetic acid treatment in reducing Escherichia coli O157:H7, Salmonella Enteritidis and Bacillus subtilis populations inoculated on fenugreek seeds and black pepper. Treatment with gaseous acetic acid at 0.3 mmol/L, 0.6 mmol/L and 4.7 mmol/L for 1-3 h significantly reduced the populations of E. coli O157:H7 and Salmonella Enteritidis on black pepper and fenugreek seeds at 55 °C (p < 0.05). The gas treatments at 4.7 mmol/L were more effective in inactivating the pathogens than the treatment at 0.3 mmol/L. An approximately 5.0 log reduction was obtained after 3 h of treatment with 4.7 mmol/L acetic acid. No significant reductions in the population of B. subtilis spores inoculated on fenugreek seeds and black pepper were obtained after the gas treatments at 0.3 mmol/L or 0.6 mmol/L (p > 0.05). However, the gas treatment at 4.7 mmol/L significantly reduced B. subtilis spores (p < 0.05), and 4.0 log CFU/g and 3.5 log CFU/g reductions on fenugreek seeds and black pepper, respectively, were obtained after 3 h of treatment.

The aim of this study was to evaluate the bactericidal effect of calcium oxide (CaO) against Pseudomonas aeruginosa biofilms on quail eggshells and major egg contacting surfaces (stainless steel, plastic, and rubber). The samples were subjected to CaO treatments (0%, 0.01%, 0.05%, 0.10%, 0.15%, 0.20%, 0.25%, and 0.30%) for 1 min. All the CaO treatments significantly reduced P. aeruginosa biofilms on all tested surfaces as compared to controls. In comparison of biofilm stability, the strongest and most resistant biofilm was formed on eggshell against the CaO treatment, followed by rubber, stainless steel, and plastic. In evaluation of bactericidal effect, the largest reduction (3.16 log CFU) was observed in plastic even at the lowest concentration of CaO (0.01%), whereas the least reduction was found in eggshells, regardless of CaO concentration. In addition, stainless steel showed a significant reduction in biofilm formation at all concentrations except 0.10% to 0.15% CaO. At 0.30% CaO, the reduction of P. aeruginosa in biofilms on stainless steel, plastic, rubber, and eggshell were 5.48, 6.37, 4.87, and 3.14 log CFU/cm 2 (CFU/egg), respectively. Biofilm reduction after CaO treatment was also observed by field emission scanning electron microscopy (FE-SEM). Based on the FE-SEM images, we observed that P. aeruginosa biofilms formed compact aggregations on eggshell surfaces with CaO treatments up to 0.30%. More specifically, a 0.20% CaO treatment resulted in the reductions of 3 to 6 log CFU in all materials. © 2017 Institute of Food Technologists®.

Epidural blood patch for refractory low CSF pressure headache: a pilot study.

2011-08-01

Once believed an exceedingly rare disorder, recent evidence suggests that low cerebrospinal fluid (CSF) pressure headache has to be considered an important cause of new daily persistent headaches, particularly among young and middle-aged individuals. Treatment of low CSF pressure headache consists of non-invasive/conservative measures and invasive measures with epidural blood patch providing the cornerstone of the invasive measures. In the present pilot study we therefore aimed to evaluate the treatment efficacy of epidural blood patch (EBP) in treatment-refractory low-pressure headache. Our primary effect parameter was total headache burden defined as area under the curve (AUC: intensity × duration) and as secondary effect parameters we identified: intensity (VAS 0-10), frequency (days per month), duration in hours (total hours/month) and also medication days (days on medication/month). In our primary effect parameter we found a significant reduction in AUC with more than 25% and this is considered to be clinically relevant. We found also a significant and relevant reduction at -22% in intensity. A trend towards reduction in duration was seen. We found no statistically significant reduction in frequency. An increase in days with use of medication was found. Increased awareness of low CSF pressure headache is emphasized and a controlled larger randomized study is needed to confirm the results. However the present results, allows us to conclude that EBP in treatment-refractory low CSF pressure headache can be considered as a treatment option.

Poultry processing antimicrobial interventions are critical for pathogen control, and organic, mobile operations in Washington seek alternatives to chlorine. Laboratory and field studies (three replications each) evaluated lactic acid efficacy as a chlorine alternative. For the laboratory study, retail-purchased, conventionally processed chicken wings inoculated with Salmonella were randomly assigned to the following treatments: Salmonella inoculation followed by no treatment (10 wings) or by 3-min rinses of water, 50 to 100 ppm of chlorine, or 2% lactic acid (20 wings for each rinse treatment). Wings were sampled for Salmonella enumeration on xylose lysine desoxycholate agar. During pastured poultry processing at mobile slaughter units for each field study replication, 20 chicken carcasses were randomly assigned to each treatment: untreated control or 3-min immersion in lactic acid or chlorine. Whole-carcass rinses were examined for aerobic plate count (APC) on tryptic soy agar and coliforms on violet red bile agar. Untreated controls were also examined for Salmonella. In the laboratory study, lactic acid produced a significant (P < 0.01) Salmonella reduction compared with the inoculated no-rinse, water, and chlorine treatments, which were statistically similar to each other. In the field study, no Salmonella was detected on untreated controls. Lactic acid produced significant >2-log (P < 0.01) reductions in APC and coliforms, whereas chlorine resulted in slight, but significant 0.4-log reductions (P < 0.01) and 0.21-log reductions (P < 0.05) in APC and coliforms compared with untreated controls. Considering laboratory and field studies, lactic acid produced greater reductions in Salmonella, APC, and coliforms, validating its effectiveness as a chlorine alternative in mobile poultry slaughter operations.

Reduction of Salmonella on alfalfa seeds using peroxyacetic acid and a commercial seed washer is as effective as treatment with 20 000 ppm of Ca(OCl)2.

The efficacy of a commercial seed washer and 1 and 3% peroxyacetic acid or 20 000 ppm calcium hypochlorite for reducing Salmonella on alfalfa seeds was investigated. Alfalfa seeds were inoculated with Salmonella Stanley to achieve c. 5 log CFU g(-1). Seeds were then treated with 1 or 3% peroxyacetic acid or 20 000 ppm calcium hypochlorite for 15 min in a commercial seed washer that uses air to enhance contact of the sanitizer with the seed. Experiments were also conducted using industry and laboratory methods. An c. 1-log reduction in number of Salm. Stanley was demonstrated regardless of the chemical treatment or method of treatment. Although this 1-log reduction was significant (P < 0.05), differences among the treatments were not significant. Treating the seed with 1 and 3% peroxyacetic acid resulted in similar Salm. Stanley reductions of 1.77 and 1.34 log, respectively, not being statistically significant (P > 0.05). These results suggest that under conditions tested, 1 or 3% peroxyacetic acid solutions are equally effective as 20 000 ppm of Ca(OCl)2 in the reduction of Salm. Stanley on alfalfa seed when used in conjunction with a commercial seed washer. A 1% peroxyacetic acid solution could potentially be used in place of 20 000 ppm of Ca(OCl)2 for treatment of seeds used for sprouting. The commercial seed washer did not enhance removal of Salm. Stanley from alfalfa seeds, but did facilitate removal of excess soil from seeds. © 2010 The Authors. Journal compilation © 2010 The Society for Applied Microbiology.

To assess the clinical efficacy and safety of a treatment based on one cycle versus two cycles of intra-articular injections of plasma rich in growth factors (PRGF-Endoret) on patients with knee osteoarthritis (OA). Ninety patients with knee OA were included and evaluated. A total of 48 patients received one cycle (OC group) (3 injections on a weekly basis), while 42 patients received two cycles of PRGF-Endoret (TC group) spaced 6 months between them. Patients were evaluated with LEQUESNE and WOMAC scores before treatment and after 48 weeks. Safety assessment was also performed. A significant reduction of all assessed outcome measures was shown for both groups at 48 weeks compared with baseline values (P < 0.001). Patients of TCs group showed a significantly higher reduction (P < 0.05) in WOMAC stiffness subscales. Regarding LEQUESNE INDEX, a significantly higher reduction was observed in the TC group in all subscales except in pain score. In the maximum walking distance subscale (MCD), the improvement rate was 31.8% higher for the TCs group compared with the OC group (P < 0.01). In addition, the TC group showed a significant improvement in LEQUESNE activities of daily living (ADV) and global subscales of 14.7 and 11.8% (P < 0.05) higher, respectively, than the OC group. Treatment with two cycles of PRGF did not show a significantly higher pain reduction compared with one cycle treatment. However, two cycles of PRGF showed a significant improvement in WOMAC stiffness, LEQUESNE MCD, LEQUESNE ADV and LEQUESNE global subscales. Therefore, patients treated with two cycles present an improvement in quality of life. II.

Induced change of formative processes in pepper (Capsicum annuum L. ). I. Effect of mutagenic treatment on the crossingover frequency of the linked and recombination of unlinked marker genes

Samovol, A.P.

The effect of mutagenic treatment of the F/sub 1/ seeds of pepper on the crossingover frequency in the al/sub 2/-b segment, monohybrid and dihybrid segregation for the unlinked marker genes al/sub 2/ and pi was studied. It has been demonstrated that treatment leads to a significant reduction in the crossover frequency in the al/sub 2/-b zone. Highly significant differences between the control and individual treatment of the hybrid seeds indicated reduction in recombinations due to the mutagens used. A case of induced deviation in independent segregation of al/sub 2/ and pi, i.e., quasilinkage has been recorded.

Decline in infection-related morbidities following drug-mediated reductions in the intensity of Schistosoma infection: A systematic review and meta-analysis

Background Since 1984, WHO has endorsed drug treatment to reduce Schistosoma infection and its consequent morbidity. Cross-sectional studies suggest pre-treatment correlation between infection intensity and risk for Schistosoma-related pathology. However, evidence also suggests that post-treatment reduction in intensity may not reverse morbidity because some morbidities occur at all levels of infection, and some reflect permanent tissue damage. The aim of this project was to systematically review evidence on drug-based control of schistosomiasis and to develop a quantitative estimate of the impact of post-treatment reductions in infection intensity on prevalence of infection-associated morbidity. Methodology/Principal findings This review was registered at inception with PROSPERO (CRD42015026080). Studies that evaluated morbidity before and after treatment were identified by online searches and searches of private archives. Post-treatment odds ratios or standardized mean differences were calculated for each outcome, and these were correlated to treatment-related egg count reduction ratios (ERRs) by meta-regression. A greater ERR correlated with greater reduction in odds of most morbidities. Random effects meta-analysis was used to derive summary estimates: after treatment of S. mansoni and S. japonicum, left-sided hepatomegaly was reduced by 54%, right-sided hepatomegaly by 47%, splenomegaly by 37%, periportal fibrosis by 52%, diarrhea by 53%, and blood in stools by 75%. For S. haematobium, hematuria was reduced by 92%, proteinuria by 90%, bladder lesions by 86%, and upper urinary tract lesions by 72%. There were no consistent changes in portal dilation or hemoglobin levels. In sub-group analysis, age, infection status, region, parasite species, and interval to follow-up were associated with meaningful differences in outcome. Conclusion/Significance While there are challenges to implementing therapy for schistosomiasis, and praziquantel therapy is not fully curative, reductions in egg output are significantly correlated with decreased morbidity and can be used to project diminution in disease burden when contemplating more aggressive strategies to minimize infection intensity.

The aim of this study was to evaluate the effectiveness of a radial firing tip of an Er,Cr:YSGG laser as an adjunct to a nonsurgical periodontal treatment. Twelve patients with chronic or aggressive periodontitis were treated by conventional periodontal treatment using ultrasonic devices and hand instruments and, additionally, in two quadrants with an Er,Cr:YSGG laser. A new radial firing tip (RFPT 14-5, Biolase) was used with 1.5 W, 30 Hz, 11% air, 20% water, and pulse duration 140 μs. Microbiological smears were taken before treatment, one day after lasing, and three and six months after lasing. Pocket depths of all periodontal sites were measured before and six months after treatment. The total bacterial load of Prevotella intermedia, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Porphyromonas gingivalis, and Aggregatibacter actinomycetemcomitans inside the pocket was reduced significantly throughout the whole examination time. Greater pocket depth reductions were observed in all groups. There was a slight higher reduction of pocket depth in the lased group after six months. These results support the thesis that Er,Cr:YSGG laser supported periodontal treatment leads to a significant reduction of periopathogenes and thereby helps the maintenance of periodontal health.

Recently published case reports and outcome studies support the use of liposuction alone as an effective technique for ameliorating symptoms of breast hypertrophy. This study is the first prospective trial to examine the effectiveness of liposuction breast reduction as a primary modality of breast reduction. In addition, this study examines the role that liposuction breast reduction can play in the treatment of African American women, given the known scarring difficulties that darker skinned patients can encounter with traditional breast reduction surgery. Twenty African American women were recruited through newspaper and Internet advertisements. Patients aged 20 to 60 years were serially accepted to the study. Patients with a chief complaint of breast ptosis were excluded. No other exclusion criteria were used. Previously validated questionnaire instruments were used preoperatively and postoperatively to measure breast-related symptoms, general patient health perception, bodily pain, and self-esteem. Comorbid conditions, demographics, financial status, prior treatments, and smoking history were also documented. Seventeen patients completed the preoperative and postoperative questionnaires. An average of 1075 cc of tissue was removed per breast during liposuction breast reduction surgery. Postoperative assessment showed a significant decrease in breast-related symptoms, a significant decrease in patient pain, and a significant improvement in overall patient health perception. Liposuction breast reduction is a useful breast reduction modality in the properly selected patient. African American women, who may traditionally forego breast reduction surgery because of scarring, are excellent candidates for this type of reduction procedure.

The aim of this Stage I Behavioral Development Trial was to develop a manual-based 12-session Women's Recovery Group (WRG) and to pilot test this new treatment in a randomized controlled trial against a mixed-gender Group Drug Counseling (GDC), an effective manual-based treatment for substance use disorders. After initial manual development, two pre-pilot groups of WRG were conducted to determine feasibility and initial acceptability of the treatment among subjects and therapists. In the pilot stage, women were randomized to either WRG or GDC. No significant differences in substance use outcomes were found between WRG and GDC during the 12-week group treatment. However, during the 6-month post-treatment follow-up, WRG members demonstrated a pattern of continued reductions in substance use while GDC women did not. In addition, pilot WRG women with alcohol dependence had significantly greater reductions in average drinks/drinking day than GDC women 6 months post-treatment (p<.03, effect size=0.81). While satisfaction with both groups was high, women were significantly more satisfied with WRG than GDC (p<.009, effect size=1.11). In this study, the newly developed 12-session women-focused WRG was feasible with high satisfaction among participants. It was equally effective as mixed-gender GDC in reducing substance use during the 12-week in-treatment phase, but demonstrated significantly greater improvement in reductions in drug and alcohol use over the post-treatment follow-up phase compared with GDC. A women-focused single-gender group treatment may enhance longer-term clinical outcomes among women with substance use disorders.

The aim of this meta-analysis was to evaluate the benefits and potential adverse effects of adding spironolactone to standard antidiabetic/renoprotective/antihypertensive (AD/RP/AHT) treatment in patients with diabetic nephropathy (DN). PubMed/MEDLINE and Web of Knowledge were searched for relevant randomized, controlled studies (RCTs) or quasi-RCTs of the effects of adding spironolactone to standard AD/RP/AHT treatment in patients with DN. Results were summarized with a random-effects model or a fixed-effects model. According to the outcomes measured (benefits and risks of adding spironolactone to standard AD/RP/AHT treatment), compared with controls, the addition of spironolactone significantly decreased end-of-treatment (EOT) 24-hour urinary albumin/protein excretion and significantly increased percentage reduction from baseline in urinary albumin/creatinine ratio (UACR), although it did not significantly affect EOT UACR. The addition of spironolactone further led to a significantly greater reduction from baseline in glomerular filtration rate (GFR)/estimated (e) GFR, although it did not significantly affect EOT GFR/eGFR. Further, the addition of spironolactone significantly reduced EOT in-office, 24-hour, and daytime systolic and diastolic blood pressure (SBP and DBP, respectively) and led to significantly greater reductions from baseline in in-office SBP and DBP, although it did not significantly affect nighttime SBP or DBP. Finally, the addition of spironolactone significantly increased mean serum/plasma potassium levels and the risk for hyperkalemia. Spironolactone could be added to preexisting AD/RP/AHT therapy in patients with DN to prevent or slow DN progression by reducing proteinuria. The addition of spironolactone would likely provide even more beneficial effect in patients with DN and hypertension due to the BP reduction associated with spironolactone use. However, the beneficial effects of spironolactone add-on should be weighed against its potential risks, especially hyperkalemia. The long-term effects of spironolactone add-on on renal outcomes and mortality need to be studied. Copyright © 2015. Published by Elsevier Inc.

Robust Reductions of Excess Weight and Hyperphagia by Beloranib in Rat Models of Genetic and Hypothalamic Obesity.

Elfers, Clinton T; Roth, Christian L

2017-01-01

Hypothalamic lesions or deficient melanocortin (MC) signaling via MC4 receptor (MC4r) mutations often lead to hyperphagia and severe treatment-resistant obesity. We tested the methionine aminopeptidase 2-inhibitor beloranib (ZGN-440) in 2 male rat models of obesity, one modeling hypothalamic obesity with a combined medial hypothalamic lesion (CMHL) and the other modeling a monogenic form of obesity with MC4r mutations (MC4r knockout [MC4rKO]). In CMHL rats (age 3 months), postsurgery excess weight gain was significantly inhibited (ZGN-440, 0.2 ± 0.7 g/d; vehicle, 3.8 ± 0.6 g/d; P < 0.001) during 12 days of ZGN-440 treatment (0.1 mg/kg daily subcutaneously) together with a 30% reduction of daily food intake vs vehicle injection. In addition, ZGN-440 treatment improved glucose tolerance and reduced plasma insulin, and circulating levels of α-melanocyte stimulating hormone were increased. Serum lipid levels did not differ significantly in ZGN-440-treated vs vehicle-treated rats. Similar results were found in MC4rKO rats: ZGN-440 treatment (14-21 d) was associated with significant reductions of body weight gain (MC4rKO, -1.7 ± 0.6 vs 2.8 ± 0.4 g/d; lean wild-type controls, -0.7 ± 0.2 vs 1.7 ± 0.7 g/d; ZGN-440 vs vehicle, respectively), reduction of food intake (MC4rKO, -28%; lean controls, -7.5%), and insulin resistance, whereas circulating levels of interleukin-1β did not change. In both obesity models, body temperature and locomotor activity were not affected by ZGN-440 treatment. In conclusion, the robust reduction of body weight in response to ZGN-440 observed in rats with severe obesity is related to a strong reduction of food intake that is likely related to changes in the central regulation of feeding.

Two occlusal splints, the full-arch stabilization splint and the anterior midline point stop (AMPS) device, were evaluated for their efficiency in relieving myogenous temporomandibular disorders (TMD). One hundred and fourteen patients with myogenous TMD were distributed into 3 groups. The first group was treated with the AMPS device, the second with the stabilization splint, and the third group was the control group. Pain intensity was scored using the visual analogue scale before treatment and 1 month and 3 months after treatment. Statistical Package for the Social Sciences (SPSS, Chicago, Ill) and multiple comparisons tests were used to compare results before and after treatment and to compare the groups. The use of AMPS device in the first group resulted in a significant improvement after 1 month and 3 months (P < or = .001) and showed a 56.66% pain reduction. A significant improvement was also noticed in the second group (P = .001) with a 47.71% pain reduction. Although pain reduction percentage appeared more in the first group, this was not statistically significant. There was a highly significant difference between groups treated with both kinds of splints and the control group. It was concluded that both types of occlusal splints are beneficial to patients with myogenous TMD.

To evaluate the efficacy of a multidisciplinary stress treatment programme. General practitioners referred 198 employed patients on sick leave with symptoms of persistent work-related stress. Using a waitlisted randomised controlled trial design, the participants were randomly divided into the following three groups: the intervention group (IG, 69 participants); treatment-as-usual control group (TAUCG, 71 participants), which received 12 consultations with a psychologist, and the waitlisted control group (WLCG, 58 participants). The stress treatment intervention consisted of nine 1-hour sessions conducted over 3 months. The goals of the sessions were the following: (1) identifying relevant stressors; (2) changing the participant's coping strategies; (3) adjusting the participant's workload and tasks, and (4) improving workplace dialogue. Each participant also attended a mindfulness-based stress reduction (MBSR) course for 2 h a week over 8 weeks. The IG and TAUCG showed significantly greater symptom level (Symptom Check List 92) reductions compared to the WLCG. Regarding the return to work (RTW) rate, 67% of participants in the IG returned to full-time work after treatment, which was a significantly higher rate than in the TAUCG (36%) and WLCG (24%). Significantly more participants in the IG (97%) increased their working hours during treatment compared with the participants in the control groups, TAUCG (71%) and WLCG (64%). The stress treatment programme--a combination of work place-focused psychotherapy and MBSR--significantly reduced stress symptom levels and increased RTW rates compared with the WLCG and TAUCG.

To evaluate the effect of treatment escalation on the rate of visual field progression in patients with primary open-angle glaucoma (POAG). Multicenter database study. We reviewed the electronic records of 171 patients with POAG under medical hypotensive treatment who underwent 5 consecutive visits 6 months apart before and after medical treatment escalation or additive laser trabeculoplasty. We calculated the rate of visual field progression (mean deviation change per year) before and after treatment escalation. The mean duration of follow-up was 5.1±0.5 years and the mean number of visual field examinations was 10.2±0.2. In 139 eyes with medical treatment escalation, the rate of progression was significantly reduced [from -0.57 to -0.29 dB/y; P=0.022; intraocular pressure (IOP) reduction 11.1%]. In detail, the rate of progression was significantly reduced after escalation from mono to dual therapy, dual to triple therapy, and from mono to triple therapy (-0.35 to -0.24 dB/y, P=0.018; -1.01 to -0.48 dB/y, P=0.038; -1.04 to -0.35 dB/y, P=0.020, respectively). In 32 eyes with additive laser trabeculoplasty, the rate of progression was significantly reduced (-0.60 to -0.24 dB/y; P=0.014; IOP reduction 9.4%). Medical treatment escalation or additive laser trabeculoplasty significantly reduced the rate of visual field progression in POAG. Larger IOP reduction has a greater probability of reducing glaucoma progression.

The present study was designed to evaluate the effects of metformin on metabolic and endocrine parameters in patients with polycystic ovary syndrome (PCOS). The study included 40 patients with PCOS. Patients were divided into 2 groups based on whether they will receive metformin (500 mg 3 times a day, n=20) or placebo (n=20) for 3 consecutive months. Serum concentrations of fasting blood glucose, insulin, HOMA-IR, INSL-3, visfatin, FSH, and LH were measured at baseline and after 3 months of therapy. The key endocrine and metabolic parameters significantly changed after metformin treatment. The systolic and diastolic blood pressures were significantly reduced in the metformin group after treatment compared to placebo (p<0.001). A significant reduction in the size of the right ovary was observed after metformin treatment (p=0.05), while no change was found in the size of left ovary (p>0.12). Moreover, a significant reduction was observed in the serum levels of FSH (p>0.01), LH (p>0.001), and visfatin (p>0.001) after metformin treatment. However, HOMA-IR (which is used to assess insulin resistance) failed to reach the statistical significance (p=0.20). We conclude that metformin treatment in females with PCOS showed significant improvement in systolic and diastolic blood pressures. In addition, an improvement in the hormonal profile in the form of reduction in LH, FSH, and visfatin levels was observed. Thus, therapeutic intervention with metformin could be of clinical importance in high-risk group of young females with PCOS. © Georg Thieme Verlag KG Stuttgart · New York.

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

Cold plasma (CP) is a novel nonthermal technology, potentially useful in food processing settings. Berries were treated with atmospheric CP for 0, 15, 30, 45, 60, 90, or 120 s at a working distance of 7.5 cm with a mixture of 4 cubic feet/minute (cfm) of CP jet and 7 cfm of ambient air. Blueberries were sampled for total aerobic plate count (APC) and yeast/molds immediately after treatment and at 1, 2, and 7 days. Blueberries were also analyzed for compression firmness, surface color, and total anthocyanins immediately after each treatment. All treatments with CP significantly (P < 0.05) reduced APC after exposure, with reductions ranging from 0.8 to 1.6 log CFU/g and 1.5 to 2.0 log CFU/g compared to the control after 1 and 7 days, respectively. Treatments longer than 60s resulted in significant reductions in firmness, although it was demonstrated that collisions between the berries and the container contributed significantly to softening. A significant reduction in anthocyanins was observed after 90 s. The surface color measurements were significantly impacted after 120 s for the L* and a* values and 45 s for the b* values. CP can inactivate microorganisms on blueberries and could be optimized to improve the safety and quality of produce. Published by Elsevier Ltd.

The present study aimed to investigate the effect of fisetin on proliferation and apoptosis of gastric cancer cells, as well as the underlying mechanism. Proliferation in SGC7901 cancer and GES-1 normal cells was analyzed using a CCK-8 assay. Apoptosis was analyzed using an Annexin V/Propidium Iodide apoptosis kit and phosphorylation of extracellular signal-regulated kinase (ERK) 1/2 was analyzed by western blot assay. Treatment of SGC7901 cells with various concentrations (1, 5, 10, 15 and 20 µM) of fisetin for 48 h resulted in a concentration dependent reduction in proliferation. Flow cytometry revealed a marked increase in apoptosis from 5 µM concentration of fisetin after 48 h. The percentage of apoptotic cells increased to 87% following treatment with 15 µM fisetin for 48 h, compared with 2% in control. Treatment of SGC7901 cells with fisetin for 48 h resulted in a reduction in the activation of ERK 1/2 in a concentration-dependent manner. The reduction in activation of ERK 1/2 was significant following treatment with 15 µM fisetin for 48 h. The inhibitory effect of fisetin on activation of ERK 1/2 was further demonstrated using the ERK 1/2 inhibitor, PD98059. The results indicated a significant reduction in the proliferation of SGC7901 cells following treatment with PD98059 (P<0.002). The reduction by PD98059 administration was comparable to that observed following fisetin treatment for 48 h. In conclusion, the current study demonstrates that fisetin inhibits the proliferation of gastric cancer cells and induces apoptosis through suppression of ERK 1/2 activation. Thus, fisetin may have therapeutic applications in the treatment of gastric cancer. PMID:29805580

MEDLINE/PUBMED, The Cochrane Library, Clinical Trials, SciELO and LILACS were searched for studies published until December 2014. Included articles were: prospective studies; including patients older than 18 years, diagnosed with periodontitis and rheumatoid arthritis submitted to non-surgical periodontal treatment; with a control group receiving no periodontal treatment; with outcomes including at least one marker of rheumatoid arthritis activity. Methodological quality of the studies was assessed using PEDro scale. Quantitative data were pooled in statistical meta-analysis using Review Manager 5. Four articles were included. Non-surgical periodontal treatment was associated with a significant reduction of DAS28 (OR: -1.18; 95% CI: -1.43, -0.93; p<0.00001). Erythrocyte sedimentation rate, C-reactive protein, patient's assessment of rheumatoid activity using visual analogical scale, tender and swollen joint counts showed a trend toward reduction (not statistically significant). The reduction of DAS 28 in patients with rheumatoid arthritis after periodontal treatment suggests that the improvement of periodontal condition is beneficial to these patients. Further randomized controlled clinical trials are necessary to confirm this finding. Copyright © 2016. Published by Elsevier Editora Ltda.

This pilot study aimed to evaluate the feasibility of an assessor-blind, randomised controlled trial of psychodynamic art therapy for the treatment of patients with schizophrenia, and to generate preliminary data on the efficacy of this intervention during acute psychotic episodes. Fifty-eight inpatients with DSM-diagnoses of schizophrenia were randomised to either 12 twice-weekly sessions of psychodynamic group art therapy plus treatment as usual or to standard treatment alone. Primary outcome criteria were positive and negative psychotic and depressive symptoms as well as global assessment of functioning. Secondary outcomes were mentalising function, estimated with the Reading the mind in the eyes test and the Levels of emotional awareness scale, self-efficacy, locus of control, quality of life and satisfaction with care. Assessments were made at baseline, at post-treatment and at 12 weeks' follow-up. At 12 weeks, 55% of patients randomised to art therapy, and 66% of patients receiving treatment as usual were examined. In the per-protocol sample, art therapy was associated with a significantly greater mean reduction of positive symptoms and improved psychosocial functioning at post-treatment and follow-up, and with a greater mean reduction of negative symptoms at follow-up compared to standard treatment. The significant reduction of positive symptoms at post-treatment was maintained in an attempted intention-to-treat analysis. There were no group differences regarding depressive symptoms. Of secondary outcome parameters, patients in the art therapy group showed a significant improvement in levels of emotional awareness, and particularly in their ability to reflect about others' emotional mental states. This is one of the first randomised controlled trials on psychodynamic group art therapy for patients with acute psychotic episodes receiving hospital treatment. Results prove the feasibility of trials on art therapy during acute psychotic episodes and justify further research to substantiate preliminary positive results regarding symptom reduction and the recovery of mentalising function.

Recent studies have questioned the value of adding whole-brain radiotherapy (WBRT) to stereotactic radiosurgery (SRS) for brain metastasis treatment. Neurotoxicity, including radiation-induced brain volume reduction, could be one reason why not all patients benefit from the addition of WBRT. In this study, we quantified brain volume reduction after WBRT and assessed its prognostic significance. Brain volumes of 91 patients with cerebral metastases were measured during a 150-day period after commencing WBRT and were compared with their pretreatment volumes. The average daily relative change in brain volume of each patient, referred to as the "brain volume reduction rate," was calculated. Univariate and multivariate Cox regression analyses were performed to assess the prognostic significance of the brain volume reduction rate, as well as of 3 treatment-related and 9 pretreatment factors. A one-way analysis of variance was used to compare the brain volume reduction rate across recursive partitioning analysis (RPA) classes. On multivariate Cox regression analysis, the brain volume reduction rate was a significant predictor of overall survival after WBRT (P < 0.001), as well as the number of brain metastases (P = 0.002) and age (P = 0.008). Patients with a relatively favorable prognosis (RPA classes 1 and 2) experienced significantly less brain volume decrease after WBRT than patients with a poor prognosis (RPA class 3) (P = 0.001). There was no significant correlation between delivered radiation dose and brain volume reduction rate (P = 0.147). In this retrospective study, a smaller decrease in brain volume after WBRT was an independent predictor of longer overall survival. © The Author(s) 2017.

2015-01-01

The main objectives of this work were to investigate the effect of atmospheric cold plasma (ACP) against a range of microbial biofilms commonly implicated in foodborne and healthcare associated human infections and against P. aeruginosa quorum sensing (QS)-regulated virulence factors, such as pyocyanin, elastase (Las B) and biofilm formation capacity post-ACP treatment. The effect of processing factors, namely treatment time and mode of plasma exposure on antimicrobial activity of ACP were also examined. Antibiofilm activity was assessed for E. coli, L. monocytogenes and S. aureus in terms of reduction of culturability and retention of metabolic activity using colony count and XTT assays, respectively. All samples were treated ‘inpack’ using sealed polypropylene containers with a high voltage dielectric barrier discharge ACP generated at 80 kV for 0, 60, 120 and 300 s and a post treatment storage time of 24 h. According to colony counts, ACP treatment for 60 s reduced populations of E. coli to undetectable levels, whereas 300 s was necessary to significantly reduce populations of L. monocytogenes and S. aureus biofilms. The results obtained from XTT assay indicated possible induction of viable but non culturable state of bacteria. With respect to P. aeruginosa QS-related virulence factors, the production of pyocyanin was significantly inhibited after short treatment times, but reduction of elastase was notable only after 300 s and no reduction in actual biofilm formation was achieved post-ACP treatment. Importantly, reduction of virulence factors was associated with reduction of the cytotoxic effects of the bacterial supernatant on CHO-K1 cells, regardless of mode and duration of treatment. The results of this study point to ACP technology as an effective strategy for inactivation of established biofilms and may play an important role in attenuation of virulence of pathogenic bacteria. Further investigation is warranted to propose direct evidence for the inhibition of QS and mechanisms by which this may occur. PMID:26390435

The synergistic effects of sequential treatments with chlorine dioxide (ClO2) and drying in killing Salmonella enterica on the surface of chicken eggshells were investigated. Initial experiments were focused on comparing lethalities of sodium hypochlorite (NaOCl) and ClO2. Eggs surface-inoculated with S. enterica in chicken feces as a carrier were immersed in water, NaOCl (50 or 200 μg/mL), or ClO2 (50 or 200 μg/mL) for 1 or 5 min. For 1-min treatments, lethal activities of sanitizers were not significantly different (P>0.05). However, after treatment with ClO2 for 5 min, reductions of S. enterica were significantly greater (P≤0.05) than reductions after treatment with water or NaOCl. The effect of treatment of eggs with ClO2 or NaOCl, followed by drying at 43% relative humidity and 25 °C for 24 and 48 h, were determined. Populations of S. enterica decreased during drying, regardless of the type of sanitizer treatment. ClO2 treatment, compared to water or NaOCl treatments, resulted in additional reductions of ca. >1.3 log CFU/egg during drying. This indicates that sequential treatments with ClO2 and drying induced synergistic lethal effects against S. enterica on the surface of eggshells. These observations will be useful when selecting a sanitizer to control S. enterica on the surface of eggshells and designing an effective egg sanitization system exploiting the synergistic lethal effects of sanitizer and drying.

Despite previous evidence supporting the use of the Cigarette Purchase Task (CPT) as a valid tool for assessing smoking reinforcement, research assessing how environmental changes affect CPT performance is scarce. This study addressed for the first time the differential effect of treatment condition [Cognitive Behavioral Treatment (CBT) + Behavioral Activation (BA) versus CBT + BA + Contingency Management (CM)] on cigarette demand among treatment seeking smokers with depressive symptoms. It also sought to assess whether reductions in smoking consumption arranged over the course of an intervention for smoking cessation impact on in-treatment cigarette demand. Participants were 92 smokers with depressive symptoms from a randomized clinical trial that received eight weeks of either CBT + BA or CBT + BA + CM. Individuals completed the CPT 8 times; the first during the intake visit and the remaining 7 scheduled once a week in midweek sessions. Cotinine samples were collected in each session. Participants receiving CBT + BA + CM showed higher reduction in cigarette demand across sessions than participants receiving CBT + BA, although this comparison was only significant for the intensity index (p = .004). Cotinine was positively related to cigarette demand (all p values < .001), although this association became less prominent across sessions. In-treatment cotinine decreases were associated with demand reductions (all p values < .001), but this association was not significant for elasticity. Reductions in nicotine intake arranged over the course of an intervention for smoking cessation impact in-treatment cigarette demand. Copyright © 2018 Elsevier Ltd. All rights reserved.

The Acute and Chronic Effects of the Novel Anticonvulsant Lacosamide in an Experimental Model of Status Epilepticus

Wasterlain, Claude G.; Stöhr, Thomas; Matagne, Alain

2011-01-01

The effective management of status epilepticus (SE) continues to be a therapeutic challenge. The aim of this study was to investigate the efficacy of lacosamide treatment in an experimental model of self-sustaining SE. Rats were treated with lacosamide (3, 10, 30 or 50 mg/kg) either 10 minutes (early treatment) or 40 minutes (late treatment) after the initiation of perforant path stimulation. Early lacosamide treatment significantly and dose-dependently reduced acute SE seizure activity; late treatment showed only a non-significant trend towards reduced seizure activity. Early lacosamide treatment also dose-dependently reduced the number of spontaneous recurrent seizures following a 6-week waiting period, with 70% reduction at the highest dose tested (50 mg/kg); there was also a significant reduction in the number of spikes and the cumulative time spent in seizures. Late treatment with high-dose lacosamide (30–50 mg/kg) reduced the number of animals that developed spontaneous recurrent seizures (33% vs 100% in controls, P <0.05), but did not significantly reduce seizure severity or frequency in rats that developed spontaneous recurrent seizures.. The results presented here suggest that lacosamide deserves investigation for the clinical treatment of SE. Potential for disease modification in this rat model of self-sustaining SE will require further studies. PMID:21277168

On-treatment response of serum hepatitis C virus (HCV) is reportedly less useful to predict the outcome of anti-HCV therapy with interferon (IFN)-free regimen with direct-acting antivirals than with IFN-based regimens in clinical trials. We evaluated the significance of very early viral response after the start of therapy, which indicates direct HCV response to the drugs, on therapeutic outcome. Reductions in serum HCV-RNA levels were measured at 1 day after the start of therapy in 544 patients who underwent IFN-free direct-acting antiviral regimens. The association between these reductions and the achievement or failure of sustained virologic response (SVR) was evaluated. Patient characteristics did not influence 1-day reduction in serum HCV-RNA except for liver fibrosis. There was no difference in 1-day HCV reduction between SVR and non-SVR patients treated with a 24-week regimen. In contrast, in patients treated with a 12-week regimen, 1-day reduction was significantly greater in SVR than in non-SVR patients (P = 0.0013) and was predictive of SVR versus non-SVR (area under the receiver-operating characteristics curve: 0.80). Whereas the reduction in serum HCV-RNA levels at 1 day after the start of therapy was not associated with treatment outcomes in patients who underwent a 24-week regimen of IFN-free therapy, there was an association in patients receiving a 12-week regimen, and this reduction was predictive of SVR, thus potentially serving as a factor to identify patients at risk of treatment failure. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

The aim of this study was to analyze the effectiveness of intensive (150 - 210 sessions), short-term (10 - 14 weeks) group psychotherapy in the treatment of neurotic disorders, and selected personality disorders. The study involved 145 patients treated in day hospital due to neurotic disorders and selected personality disorders. The measurements were performed twice - at the beginning and at the end of hospitalization. The effectiveness of psychotherapy in the reduction of symptoms of neurotic disorders was measured with symptom checklist "0". The change in the severity of personality traits characteristic for neurotic disorders was examined using Neurotic Personality Questionnaire KON-2006. A significant reduction in symptoms of neurotic disorders was found in 84% of patients (85,7% women and 80,8% men). 70,3% of the examined patients obtained in the measurement at the end of treatment results indicating the level of severity of neurotic disorders symptoms below the cutoff point separating population of healthy individuals from patients. A significant reduction in the severity of personality traits characteristically occurring in patients suffering from neurotic disorders was found in 76% of patients (74.5% women and 78.7% men). 42.8% of the examined patients obtained in the measurement at the end of the treatment the value of neurotic personality traits index (X-KON) typical for healthy population. Intensive, short-term group psychotherapy with elements of individual therapy is an effective treatment for neurotic disorders. The majority of treated persons obtains a significant symptomatic improvement and a reduction in the severity of neurotic personality traits.

The aim of our study was to investigate the effects of a combined treatment with alpha-lipoic acid (ALA) and myoinositol (MYO) on clinical, endocrine and metabolic features of women affected by polycystic ovary syndrome (PCOS). In this pilot cohort study, forty women with PCOS were enrolled and clinical, hormonal and metabolic parameters were evaluated before and after a six-months combined treatment with ALA and MYO daily. Studied patients experienced a significant increase in the number of cycles in six months (p < 0.01). The free androgen index (FAI), the mean androstenedione and DHEAS levels significantly decreased after treatment (p < 0.05). Mean SHBG levels significantly raised (p < 0.01). A significant improvement in mean Ferriman-Gallwey (F-G) score (p < 0.01) and a significant reduction of BMI (p < 0.01) were also observed. A significant reduction of AMH levels, ovarian volume and total antral follicular count were observed in our studied women (p< 0.05). No significant changes occurred in gluco-insulinaemic and lipid parameters after treatment. The combined treatment of ALA and MYO is able to restore the menstrual pattern and to improve the hormonal milieu of PCOS women, even in the absence of apparent changes in insulin metabolism.

Greater occipital nerve (GON) blocks are frequently used to treat migraine headaches, although a paucity of supporting clinical evidence exists. The objective of this study was to assess the efficacy of GON block in acute treatment of migraine headache, with a focus on pain relief. This retrospective cohort study was undertaken between January 2009 and August 2014 and included patients who underwent at least 1 GON block and attended at least 1 follow-up appointment. Change in the 11-point numeric pain rating scale (NPRS) was used to assess the response to GON block. Response was defined as "minimal" (<30% NPRS point reduction), "moderate" (31-50% NPRS point reduction), or "significant" (>50% NPRS point reduction). A total of 562 patients met inclusion criteria; 423 were women (75%). Mean age was 58.6 ± 16.7 years. Of these 562, 459 patients (82%) rated their response to GON block as moderate or significant. No statistically significant relationship existed between previous treatment regimens and response to GON block. GON block was equally effective across the different age and sex groups. Greater occipital block seems to be an effective option for acute management of migraine headache, with promising reductions in pain scores. © Copyright 2018 by the American Board of Family Medicine.

This study demonstrates the possibility of using sanitizing detergents based on natural products for the elimination and/or reduction of Aeromonas hydrophila biofilm formed on stainless steel surfaces. The goal of this work was to determine the reduction effect of sanitizing detergents containing essential oils of Thymus vulgaris (thyme) and Cymbopogon citratus (lemongrass) on biofilm formed by A. hydrophila on AISI 304 stainless steel coupons, using UHT skimmed milk as substratum. There was adhesion and biofilm formation by A. hydrophila at 28 °C, presenting 7.60 log cfu.cm−2 after the fourth day of cultivation. There was no significant difference between the lemongrass treatment and that of the thyme oil (p < 0.05). However, both treatments significantly reduced the biofilm, differing significantly from the NaOH control (p > 0.05). The treatment with lemongrass solution reduced the biofilm by 4.51 log cfu cm−2 at 25 °C. The thyme detergent also reduced the number of cfu cm−2 by 3.84 log cycles at 25 °C. The use of the lemongrass and thyme solutions efficiently reduced the A. hydrophila biofilm. PMID:24159286

Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. To assess the effectiveness and safety of using an opiate, compared to a sedative or non-pharmacological treatment, for treatment of NAS due to withdrawal from opiates. The previous review was updated with additional searches of the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, Issue 1, 2005), MEDLINE (1966-December 2004) and EMBASE (1980-December 2004) supplemented by searches of conference abstracts and citation lists of published articles. Trials enrolling infants with NAS born to mothers with an opiate dependence, with > 80% follow up and using random or quasi-random allocation to opiate or control. Control could include an opiate, sedative or non-pharmacological treatment. Each author assessed study quality and extracted data independently. Primary outcomes included control of symptoms, seizure occurrence, mortality and neurodevelopment. Treatment effect was expressed using relative risk (RR), risk difference (RD), mean difference (MD) and weighted mean difference (WMD). Meta-analysis was performed using a fixed effect model. Seven studies enrolling a total of 585 infants met inclusion criteria (Carin 1983; Finnegan 1984; Jackson 2004; Kaltenbach 1986; Kandall 1983; Khoo 1995; Madden 1977); however, two (Finnegan 1984; Kaltenbach 1986) may be sequential reports that include some identical patients. The studies enrolled infants of mothers who had used opiates with or without other drugs during pregnancy. Methodological concerns included the use of quasi-random rather than random patient allocation methods in three studies; sizeable, largely unexplained differences in reported numbers allocated to each group in four studies; and imbalances in group characteristics after randomisation in one study. Opiate (morphine) vs supportive care only: One study (Khoo 1995) found no significant effect on treatment failure (RR 1.29, 95% CI 0.41, 4.07), a significant increase in hospital stay (MD 15.0 days, 95% CI 8.9, 21.1) and significant reductions in time to regain birthweight (MD -2.8 days, 95% -5.3, -0.3) and duration of supportive care (MD -197.2 minutes/day, 95% CI -274.2, -120.3). Opiate vs phenobarbitone: Meta-analysis of four studies found no significant difference in treatment failure (typical RR 0.76, 95% CI 0.51, 1.11). One of these studies (Finnegan 1984) reported that opiate treatment resulted in a significant reduction in treatment failure among infants of mothers who had used only opiates; however, as this was a post-hoc analysis, this result should be interpreted with caution. One study (Jackson 2004) reported a significant reduction in duration of treatment and admission to the nursery for infants receiving morphine compared to phenobarbitone. One study (Kandall 1983) reported a reduction in seizures, of borderline statistical significance, with the use of opiate. Opiate vs diazepam: Meta-analysis of two studies found a significant reduction in treatment failure (RR 0.43, 95% CI 0.23, 0.80) with the use of opiate. No study reported neurodevelopment by allocated treatment group. Opiates, as compared to supportive care only, appear to reduce the time to regain birth weight and reduce the duration of supportive care, but increase the duration of hospital stay; there is no evidence of effect on treatment failure. When compared to phenobarbitone, opiates may reduce the incidence of seizures but, overall, there is no evidence of effect on treatment failure. One study reported a reduction in duration of treatment and nursery admission for infants on morphine. When compared to diazepam, opiates reduce the incidence of treatment failure. A post-hoc analysis generates the hypothesis that treatment effects may vary according to whether the population includes infants born to all opiate users (i.e. with or without other drug exposure) or is restricted to infants of mothers who used opiates only. In view of the methodologic limitations of the included studies the conclusions of this review should be treated with caution.

Cellulite is a frequent skin condition for which treatment remains a challenge. A wide variety of treatments are available but most procedures offer suboptimal clinical effect and/or delayed therapeutic outcome. Only few therapeutic options have proven efficacy in the treatment of cellulite. To determine the efficacy and the safety profiles of radiofrequency and dynamic muscle activation technology in treatment of abdominal cellulite and circumference reduction. Twenty-five females with abdominal cellulite received 6 weekly radiofrequency and dynamic muscle activation treatments. Treatment areas included the abdomen and both sides of flanks. Subjects were evaluated using standardized photographs, and measurements of body weight and abdominal circumference at baseline, before every treatment visit, and 1 week and four weeks after the final treatment. Subcutaneous tissue thickness was recorded by ultrasound at baseline and 4 weeks after completion of treatment protocol. Physicians' evaluation and patient's satisfaction of clinical improvement were also measured. All subjects completed the treatment protocol and attended every follow-up visits. There was significant abdominal circumference reduction of 2.96 and 2.52 cm at 1-, and 4-week follow-up visits (p < 0.05), respectively. At four weeks after the last treatment, the average circumferential reduction was sustained. Most of the patients were rated to have 25-49% improvement at 5th treatment, and 1- and 4-week follow-up visits. Ninety-two percent of the patients were satisfied with the treatment outcome. Radiofrequency provided beneficial effects on the reduction of abdomen and cellulite appearance. The benefit of muscle activation is yet to be determined.

The current study investigated: (a) the relationships of exposure to the Adolescent Community Reinforcement Approach (A-CRA) with reductions in substance use, illegal activity, and juvenile justice system involvement in adolescents diagnosed with a substance use disorder, and (b) the pathways by which reductions in the target behaviors were achieved. This study is a secondary data analysis of longitudinal data from a large-scale implementation effort for A-CRA. The sample consisted of 1,467 adolescents who presented to substance use treatment and reported past-year engagement in illegal activity. Participants had an average age of 15.8 years (SD = 1.3) and were 25% female, 14% African American, 29% Hispanic, 35% Caucasian, 16% mixed ethnicity, and 6% other ethnicity. Path analyses provided support that participation in A-CRA had a significant, direct association with reduced substance use; a significant, indirect association with reduced illegal activity through reductions in substance use; and a significant indirect association with reduced juvenile justice system involvement through reductions in both substance use and illegal activity. In addition, post hoc analyses using a bootstrapping strategy provided evidence that reductions in substance use partially mediated the relationship between A-CRA and illegal activity.

Objective: To evaluate the efficacy of oral nattokinase (NK) in the reduction of common carotid artery intimal medial thickness (CCA-IMT) and carotid artery plaque size and in lowering blood lipids, and to explore the underlying mechanism of actions of NK and its potential clinical use. Methods: All enrolled patients were from the Out-Patient Clinic of the Department of TCM at the 3(rd) Affiliated Hospital of Sun Yat-sen University. Using randomised picking method, all patients were randomly assigned to one of two groups, NK and Statin (ST) group. NK Group-patients were given NK at a daily dose of 6 000 FU and ST Group-patients were treated with statin (simvastatin 20 mg) daily. The treatment course was 26 weeks. CCA-IMT, carotid plaque size and blood lipid profile of the patients were measured before and after treatment. Results: A total of 82 patients were enrolled in the study and 76 patients (NK 39, ST 37) completed the study. Following the treatments for 26 weeks, there was a significant reduction in CCA-IMT and carotid plaque size in both groups compared with the baseline before treatment. The carotid plaque size and CCA-IMT reduced from(0.25±0.12)cm(2) to (0.16±0.10)cm(2) and from (1.13±0.12)mm to (1.01±0.11)mm, repectively. The reduction in the NK group was significantly profound ( P <0.01, 36.6% reduction in plaque size in NK group versus 11.5% change in ST group). Both treatments reduced total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG). While the reduction in both groups was shown to be statistically significant ( P <0.01), the reduction of TC, LDL-C and TG in ST group was significantly greater ( P <0.05). In addition, NK significantly increased the level of high-density lipoprotein cholesterol (HDL-C) ( P <0.05), in contrast, HDL-C in the ST group did not change. The lipid lowering effect observed in the NK group was not correlated to the reduction of CCA-IMT and carotid artery plaque size ( r =0.35, P =0.09). Conclusions: Our findings from this pioneer clinical study suggests that daily NK supplementation is an effective way to manage the progression of atherosclerosis and potentially may be a better alternative to statins which are commonly used to reduce atherosclerosis and further to prevent cardiovascular attack and stroke in patients. The mechanism underlying the reduction of carotid atherosclerosis by NK may be independent from its lipid-lowering effect, which is different from that of statins.

The number needed to treat: a clinically useful measure of treatment effect.

The relative benefit of an active treatment over a control is usually expressed as the relative risk, the relative risk reduction, or the odds ratio. These measures are used extensively in both clinical and epidemiological investigations. For clinical decision making, however, it is more meaningful to use the measure "number needed to treat." This measure is calculated on the inverse of the absolute risk reduction. It has the advantage that it conveys both statistical and clinical significance to the doctor. Furthermore, it can be used to extrapolate published findings to a patient at an arbitrary specified baseline risk when the relative risk reduction associated with treatment is constant for all levels of risk.

Chemotherapy with praziquantel (PZQ) is the mainstay of schistosomiasis control. However, there are recent concerns about tolerance or resistance to PZQ, so that monitoring its efficacy in different settings is required. A longitudinal study was conducted to evaluate the impact of PZQ for the treatment of Schistosoma haematobium infection among schoolchildren at Al Salamania, Central Sudan. Parasitological examinations for S. haematobium were performed in a cohort of schoolchildren (6-15 years of age) before and 1 year after treatment with a single dose of PZQ 40 mg/kg. Out of 562 (309 boys and 253 girls) schoolchildren recruited from three elementary schools, 420 completed one longitudinal dataset that comprised of data from two time points; baseline, and follow-up 1 year after treatment with a single dose of PZQ 40 mg/kg for S. haematobium infection. A single dose of PZQ significantly reduced the prevalence of S. haematobium infection by 83.3% (from 51.4% to 8.6%) and the geometric mean intensity of infection of positive individuals by 17.0% (from 87.7 to 72.8 eggs/10 ml of urine) 1 year after treatment. While there was no significant difference in the reduction of the prevalence of S. haematobium infection between the gender or age groups, there was a significantly higher reduction of intensity of S. haematobium infection among girls in comparison with boys. There was a significant reduction of S. haematobium infection 1 year after PZQ treatment in this setting.

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.

Sulfuric material is formed upon oxidation of sulfidic material; it is extremely acidic, and therefore, an environmental hazard. One option for increasing pH of sulfuric material may be stimulation of bacterial sulfate reduction. We investigated the effects of organic carbon addition and pH increase on sulfate reduction after re-flooding in ten sulfuric materials with four treatments: control, pH increase to 5.5 (+pH), organic carbon addition with 2% w/w finely ground wheat straw (+C), and organic carbon addition and pH increase (+C+pH). After 36 weeks, in five of the ten soils, only treatment +C+pH significantly increased the concentration of reduced inorganic sulfur (RIS) compared to the control and increased the soil pore water pH compared to treatment+pH. In four other soils, pH increase or/and organic carbon addition had no significant effect on RIS concentration compared to the control. The RIS concentration in treatment +C+pH as percentage of the control was negatively correlated with soil clay content and initial nitrate concentration. The results suggest that organic carbon addition and pH increase can stimulate sulfate reduction after re-flooding, but the effectiveness of this treatment depends on soil properties.

Odontogenic cysts are defined as those cysts that arise from odontogenic epithelium and occur in the tooth-bearing regions of the jaws. Cystectomy, marsupialization or decompression of odontogenic cyst are treatment approach to this pathology. The aim of this study was to evaluate the effectiveness of the decompression as the primary treatment of the cystic lesions of the jaws and them reduction rates involving different factors. 23 patients with odontogenic cysts of the jaws, previously diagnosed by anatomical histopathology (follicular cysts (7) and radicular cysts (16)) underwent decompression as an initial treatment. Clinical examination and pre and post panoramic radiograph were measured and analyzed. In addition, data as gender, age, time reduction and location of the lesion were collected. Significant results were obtained in relation to the location of lesions and the reduction rate (p<0.01). In a higher initial lesion, a greater reduction rate was observed (p<0.05). Decompression as an initial treatment of cystic lesions of the jaws was effective; it reduces the size of the lesions avoiding a possible damage to adjacent structures. Cystic lesions in the mandible, regardless of the area where they occur will have a higher reduction rate if it is compared with the maxilla. Similar behavior was identified in large lesions compared to smaller.

Forests in the southeastern U.S. are predicted to experience a moderate decrease in water availability that will result in soil water deficiency during the growing season. The potential impact of drier climate on the productivity of managed loblolly pine plantations in the Southeast US is uncertain. Access to water reserves in deep soil during drought periods helps the forest buffer the effects of water deficits. To better understand the potential impact of drought on deep soil hydrology, we studied the combined effects of throughfall reduction and soil fertility on soil hydrology to the depth of 3 m in a 10-year-old loblolly pine plantation by applying a throughfall reduction treatment (ambient versus 30% throughfall reduction) and a fertilization treatment (no fertilization versus fertilization). Fertilization lowered soil moisture for all depths and differences were significant at 30-60 cm and 300 cm. Throughfall reduction also lowered soil moisture for all depths and differences were significant in the surface soils (0-30 cm) and deep soils (below 2m). Fertilization significantly decreased 10-90 cm soil water when combined with throughfall reduction treatment. HYDRUS 1-D model was used to simulate changes in the vertical distribution of soil water and to enhance our understanding of hydrologic processes. The model was accurately calibrated using 914 days of data under ambient rainfall (R2=0.84 and RMSE = 0.04). Using data under throughfall reduction treatment, the model validation showed R2=0.67 and RMSE = 0.04, suggesting that this model captures the hydrological processes of this study site. The difference in the rates of simulated cumulative actual evapotranspiration between ambient and throughfall reduction were only 10%; however, water yield as lower boundary flux decreased 64%. These empirical and simulated results suggested that when evapotranspiration exceeded precipitation, the soil water in the upper 90 cm did not satisfy the demand for AET, soil below 90 cm constantly contribute to plant water uptake. With 30% less throughfall, the water in the 3 meter soil profile can satisfy the demand of evapotranspiration before water yield.

We assessed the relationships between changes in lung compliance, lung volumes and dynamic hyperinflation in patients with emphysema who underwent bronchoscopic treatment with nitinol coils (coil treatment) (n=11) or received usual care (UC) (n=11). Compared with UC, coil treatment resulted in decreased dynamic lung compliance (C Ldyn ) (p=0.03) and increased endurance time (p=0.010). The change in C Ldyn was associated with significant improvement in FEV 1 and FVC, with reduction in residual volume and intrinsic positive end-expiratory pressure, and with increased inspiratory capacity at rest/and at exercise. The increase in end-expiratory lung volume (EELV) during exercise (EELV dyn-ch =EELV isotime EELV rest ) demonstrated significant attenuation after coil treatment (p=0.02). © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Treatment for neuropsychiatric symptoms (NPS) in dementia is insufficient. Antipsychotics and acetylcholinesterase inhibitors are used generating symptomatic improvements in behavior and cognition, but few studies have investigated their effect on Alzheimer's disease (AD) biomarkers in cerebrospinal fluid (CSF). This is a secondary analysis based on an earlier clinical trial comparing the treatment effects on NPS. The aim of this study was to examine whether treatment with risperidone and galantamine affect levels of the biomarkers T-Tau, P-Tau, Aβ1-42, and Aβ42/40-ratio in CSF. The secondary aim was to test if baseline levels of these biomarkers are associated with the clinical course of NPS. 83 patients (mean + SD 77.9.6±7.7 years) with dementia and NPS were randomized to galantamine (n = 44) or risperidone (n = 39) treatment. CSF samples were collected at baseline and after 12 weeks. Changes in levels of biomarkers between the two treatment groups did not differ significantly. Low baseline levels of Aβ1 - 42 was significantly associated with reduction of irritability at follow up. Low baseline levels of Aβ1-42, Aβ42/40, and P-Tau were significant correlates of reduction in appetite and eating disorders. CSF Aβ1-42 levels in patients treated with risperidone were significantly decreased at follow up, showing an 8% (40 pg/mL) reduction as compared with baseline (p = 0.03). Our results suggest that risperidone may affect the CSF profile of AD biomarkers indicating more amyloid pathology. Treatment with galantamine did not affect the CSF biomarkers in any direction. The AD CSF biomarkers displayed correlations with specific NPS suggesting potential research questions to be pursued.

This pilot randomized controlled trial evaluated a previously developed manualized telephone based cognitive behavioral therapy (T-CBT) intervention compared to face-to-face (f2f) therapy among low-income, urban dwelling HIV infected depressed individuals. The primary outcome was the reduction of depressive symptoms as measured by the Hamliton rating scale for depression scale. The secondary outcome was adherence to HAART as measured by random telephone based pill counts. Outcome measures were collected by trained research assistants masked to treatment allocation. Analysis was based on intention-to-treat. Thirty-four participants met eligibility criteria and were randomly assigned to receive T-CBT (n = 16) or f2f (n = 18). There was no statistically significant difference in depression treatment outcomes comparing f2f to T-CBT. Within group evaluation demonstrated that both the T-CBT and the f2f psychotherapy groups resulted in significant reductions in depressive symptoms. Those who received the T-CBT were significantly more likely to maintain their adherence to antiretroviral medication compared to the f2f treatment. None of the participants discontinued treatment due to adverse events. T-CBT can be delivered to low-income, urban dwelling HIV infected depressed individuals resulting in significant reductions in depression symptoms and improved adherence to antiretroviral medication.

Reducing delays in time to treatment is a key goal of ST-elevation myocardial infarction (STEMI) emergency care. Emergency medical services (EMS) are a critical component of the STEMI chain of survival. We sought to assess the impact of the careful integration of EMS as a strategy for improving systemic treatment times for STEMI. We conducted a study of all 747 nontransfer STEMI patients who underwent primary percutaneous coronary intervention (PCI) in Dallas County, Texas from October 1, 2010 through December 31, 2011. EMS leaders from 24 agencies and 15 major PCI receiving hospitals collected and shared common, de-identified patient data. We used 15 months of data to develop a generalized linear regression to assess the impact of EMS on two treatment metrics-hospital door to balloon (D2B) time, and symptom onset to arterial reperfusion (SOAR) time, a new metric we developed to assess total treatment times. We found statistically significant reductions in median D2B (11.1-min reduction) and SOAR (63.5-min reduction) treatment times when EMS transported patients to the receiving facility, compared to self-transport. In addition, when trained EMS paramedics field-activated the cardiac catheterization laboratory using predefined specified protocols, D2B times were reduced by 38% (43 min) after controlling for confounding variables, and field activation was associated with a 21.9% reduction (73 min) in the mean SOAR time (both with p < 0.001). Active EMS engagement in STEMI treatment was associated with significantly lower D2B and total coronary reperfusion times. Copyright © 2014 Elsevier Inc. All rights reserved.

High-concentration acrylate wastewater was treated by an electrocatalytic reduction process. The effects of the cation exchange membrane (CEM) and cathode materials on acrylate reduction were investigated. It indicated that the acrylate could be reduced to propionate acid efficiently by the electrocatalytic reduction process. The addition of CEM to separator with the cathode and anode could significantly improve current efficiency. The cathode materials had significant effect on the reduction of acrylate. The current efficiency by Pd/Nickel foam, was greater than 90%, while those by nickel foam, the carbon fibers and the stainless steel decreased successively. Toxicity of the wastewater decreased considerably and methane production rate in the biochemical methane potential (BMP) test increased greatly after the electrocatalytic reduction process.

Long-term Nasal and Peri-oral Tightening by a Single Fractional Noninsulated Microneedle Radiofrequency Treatment

PubMed Central

2017-01-01

Background: The skin tightening effects induced by non-insulated microneedle radiofrequency have proved long-lasting. Our previous three-dimensional volumetric assessment showed significant facial tightening for up to six months. However, nasal and peri-oral tightening effects lasted longer. The objective of this study was to investigate the distribution of the long-term volumetric reduction in facial area induced by a single fractional non-insulated microneedle radiofrequency treatment. Methods: Fifteen Asian patients underwent full facial skin tightening using a sharply tapered non-insulated microneedle radiofrequency applicator with a novel fractionated pulse mode. Three-dimensional volumetric assessments were performed at six and 12 months post-treatment. Patients rated their satisfaction using a 5-point scale at each follow up. Results: Objective assessments with superimposed three-dimensional color images showed significant volumetric reduction in the nasal and peri-oral areas at 12 months post-treatment in all patients. Median volumetric reductions at six and 12 months post-treatment were 13.1 and 12.3ml, respectively. All of the patients were satisfied with their results 12 months post-treatment. Side effects were not observed. Conclusions: This single fractional NIMNRF treatment provided long-lasting nasal and peri-oral tightening as shown via 3D volumetric assessment. Moreover, NIMNRF produced minimal complications, downtime, and few side effects. This approach provides safe and effective treatment of skin tightening. PMID:28367261

A double-blind, placebo-controlled trial was carried out in 17 Type 2 (non-insulin-dependent) diabetic patients, treated with diet therapy alone to study the effects of guar gum on metabolic control, serum lipids, and blood pressure levels. Thirteen of the patients had drug treatment for hypertension. Guar gum was taken with meals three times a day, and the dose was gradually increased to 21 g per day. A slight, but not significant improvement was found in the metabolic control of the patients after the guar gum treatment compared to the placebo. Serum total cholesterol was 11% (p greater than 0.01) lower after the guar gum but no significant differences were found in HDL-cholesterol or serum triglycerides during the guar gum treatment compared to the placebo. Diastolic blood pressure level was significantly lower during the guar gum treatment compared to placebo. No difference was observed in systolic blood pressure levels between the guar gum and placebo treatments. The reduction of diastolic blood pressure was independent of changes in fasting blood glucose level or body weight, but could in part be due to simultaneous reduction in serum cholesterol concentration. The changes associated with guar gum supplementation suggest a reduction in the risk for cardiovascular complications in diabetic patients.

Can Cognitive Behavioral Therapy for Insomnia also treat fatigue, pain, and mood symptoms in individuals with traumatic brain injury? - A multiple case report.

Individuals with traumatic brain injury (TBI) often develop sleep disorders post-injury. The most common one is insomnia, which can exacerbate other post-injury symptoms, including fatigue, impaired cognition, depression, anxiety, and pain. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a manualized treatment that effectively treats insomnia with secondary effects on cognition, mood, and pain in various populations. This paper reviews the use of CBT-I for three participants with TBI of different severities. Pre- and post-treatment assessments of insomnia, fatigue, depression, anxiety, and pain were conducted. Mood was further assessed at follow-up. Minimal clinically important difference (MCID) scores derived from the research literature were used to establish clinically meaningful symptom improvement on self-report questionnaires. The reduction in insomnia severity scores for all three participants were not large enough to be considered a clinically significant improvement following CBT-I, although trends toward improvement were observed. However, all participants showed clinically significant reductions in anxiety at post-treatment; the effects persisted for 2 participants at follow-up. Reductions in depression symptoms were observed for 2 participants at post-treatment, and treatment effects persisted for 1 participant at follow-up. One participant endorsed clinically significant improvements in fatigue and pain severity. We conclude that CBT-I may provide secondary benefits for symptoms commonly experienced by individuals with TBI, especially mood disturbances.

Attention management is often included in cognitive-behavioural treatments (CBT). The aim of this study was to evaluate the effects of attention management strategies in the treatment for chronic pain. The present pilot study consisted of six weekly 90-min treatment sessions and was based on a CBT attention management manual describing techniques such as attention diversion, imagery and mindfulness exercises. The intended outcomes were reduction in pain-related anxiety and hypervigilance to pain and decrease in pain impact of everyday life, measured by self-report. Information was collected at baseline, pre-treatment, post-treatment, and at 3 and 6 months follow-up. The results at the end of treatment, and at 3-month follow-up, show significant reductions in pain-related anxiety, hypervigilance and interference of pain (effect sizes 0.40-0.90). Reduction in pain-related interference and anxiety remained at the 6-month follow-up. The results indicate that attention control skills can be a useful method to reduce anxiety in the short term. Clinical implications of the results are discussed.

Reducing resistance and denial by exercising ambivalence during the treatment of addiction.

PubMed

Shaffer, H J; Simoneau, G

2001-01-01

Stage change models and motivational enhancement therapies have significantly influenced the therapeutic tactics clinicians employ in the treatment of addictive behaviors. While motivational enhancement strategies have addressed client ambivalence to increase motivation to change, this article suggests that focusing on ambivalence during treatment has even wider clinical utility than previously thought. Resistance reduction concentrates on exercising ambivalence without an investment in clients changing, thereby strengthening client tolerance for ambivalent thoughts and feelings. Exercising ambivalence reduces resistance to treatment and change by validating a wide array of possible outcomes through detailed exploration of how a behavior pattern works for a client. Since resistance reduction does not require clients to want to change for therapy to progress, exploring the decision-making process becomes paramount. A general discussion of the resistance reduction model, ambivalence, and how clients present for treatment precedes clinical case examples.

The authors sought to identify baseline clinical and sociodemographic characteristics associated with work productivity in depressed outpatients and to assess the effect of treatment on work productivity. Employed depressed outpatients 18-75 years old who completed the Work Productivity and Activity Impairment scale (N=1,928) were treated with citalopram (20-40 mg/day) in the Sequenced Treatment Alternatives to Relieve Depression study. For patients who did not remit after an initial adequate antidepressant trial (level 1), either a switch to sertraline, sustained-release bupropion, or extended-release venlafaxine or an augmentation with sustained-release bupropion or buspirone was provided (level 2). Participants' clinical and demographic characteristics and treatment outcomes were analyzed for associations with baseline work productivity and change in productivity over time. Education, baseline depression severity, and melancholic, atypical, and recurrent depression subtypes were all independently associated with lower benefit to work productivity domains. During level 1 treatment, work productivity in several domains improved with reductions in depressive symptom severity. However, these findings did not hold true for level 2 outcomes; there was no significant association between treatment response and reduction in work impairment. Results were largely confirmed when multiple imputations were employed to address missing data. During this additional analysis, an association was also observed between greater impairment in work productivity and higher levels of anxious depression. Patients with clinically significant reductions in symptom severity during initial treatment were more likely than nonresponders to experience significant improvements in work productivity. In contrast, patients who achieved symptom remission in second-step treatment continued to have impairment at work. Patients who have demonstrated some degree of treatment resistance are more prone to persistent impairment in occupational productivity, implying a need for additional, possibly novel, treatments.

The study was aimed to investigate the effect of voglibose or acarbose as an add-on treatment in overweight/obese type 2 diabetes (T2DM) patients who are uncontrolled with metformin and sulfonylureas (SUs) in Western part of India. A retrospective study included 77 participants (BMI≥25kg/m(2); HbA1c level>8% and<9.5%) with overweight/obese T2DM. These participants were treated with either voglibose or acarbose. Glycemic parameters (fasting blood glucose and glycated hemoglobin [HbA1c]), bodyweight, BMI and lipid parameters were evaluated at baseline, 3-month, 6-month and 9-month of treatment. Adverse events were also captured at respective time points. Voglibose showed significant reduction in HbA1c and bodyweight with short duration of treatment (6 months; P<0.05 and 9 months; P<0.01) whereas acarbose showed significant reduction with longer duration of treatment (9 months; P<0.05) when compared with baseline. Moreover, both treatment groups were reported with reduction in BMI. Further, significant improvement in lipid parameters except LDL and HDL were observed in both treatment groups when compared with baseline. None of participant was discontinued due to side effects of the treatment. In addition, the frequency of hypoglycemia was decreased in both treatment groups. Voglibose or acarbose as an add-on treatment with metformin and sulfonylureas in uncontrolled obese/overweight T2DM provides desired glycemic control, reduces bodyweight and improves lipid parameters with good tolerability profile.

Objective This study seeks to establish the efficacy of single-lead, 3-week peripheral nerve stimulation (PNS) therapy for pain reduction in stroke survivors with chronic hemiplegic shoulder pain. Design Single-site, pilot, randomized controlled trial for adults with chronic shoulder pain after stroke. Participants were randomized to receive a 3-week treatment of single-lead PNS or usual care (UC). The primary outcome was the worst pain in the last week (Brief Pain Inventory, Short Form question 3) measured at baseline, and weeks 1,4, 12, and 16. Secondary outcomes included pain interference (Brief Pain Inventory, Short Form question 9), pain measured by the ShoulderQ Visual Graphic Rating Scales; and health-related quality of life (SF-36v2). Results Twenty-five participants were recruited, 13 to PNS and 12 to UC. There was a significantly greater reduction in pain for the PNS group compared to controls, with significant differences at 6 and 12 weeks after treatment. Both PNS and UC were associated with significant improvements in pain interference and physical health related quality of life. Conclusions Short-term PNS is a safe and efficacious treatment for shoulder pain. Pain reduction is greater than compared to UC and is maintained for at least 12 weeks after treatment. PMID:24355994

The effect of the microalgae Chlorella vulgaris on a wide range of different pesticides in water was studied. Treatments included short-term exposure (1 h) to living and dead microalgal biomass and long-term exposure (4 days) to actively growing microalgae. The initial pesticide concentration was 63.5 ± 3.9 µg L(-1). There was no significant overall reduction of pesticides after short-term exposure. A significant reduction of the total amount of pesticides was achieved after the long-term exposure to growing microalgae (final concentration 29.7 ± 1.0 µg L(-1)) compared with the long-term control (37.0 ± 1.2 µg L(-1)). The concentrations of 10 pesticides out of 38 tested were significantly lowered in the long-term algal treatment. A high impact of abiotic factors such as sunlight and aeration for pesticide reduction was observed when the initial control (63.5 ± 3.9 µg L(-1)) and the long-term control (37.0 ± 1.2 µg L(-1)) were compared. The results suggest that water treatment using microalgae, natural inhabitants of polluted surface waters, could be further explored not only for removal of inorganic nutrients but also for removal of organic pollutants in water.

The objective of the present study was to assess factors related to long-term changes in urinary albumin excretion (UAE) of nondiabetic microalbuminuric (n = 252) or proteinuric hypertensive individuals (n = 58) in a prospective follow-up. After enrollment, patients were placed on usual care including nonpharmacological treatment and/or treatment with an antihypertensive drug regime to achieve blood pressure < 135/85 mmHg. Periodic UAE measurements were performed until regression or significant reduction (defined when UAE dropped > 50% from the initial values, plus reduction of UAE to < 30 mg/24 h for microalbuminuric patients and < 300 mg/24 h for proteinuric patients). Among the microalbuminuric patients, 113 (44.8%) significantly reduced UAE after a mean follow-up of 18 months (range 12-69 months), 20.3/100 patients per year. Among the proteinuric patients, 29 (50%) significantly reduced UAE after a mean follow-up of 25 months (range 12-51 months), 20.2/100 patients per year. The baseline glomerular filtration rate, diastolic blood pressure and fasting glucose during follow-up were independent factors related to the regression or significant reduction in a Cox proportional hazard model. Regression of UAE was independently related to initial estimated glomerular filtration rate < or = 60 ml/min per 1.73 m (hazard ratio, 0.57; 95% confidence interval, 0.38-0.86; P = 0.001) and DBP > or = 90 mmHg achieved during the follow-up (hazard ratio, 0.57; 95% confidence interval, 0.38-0.86; P = 0.001), even when adjusted for age, gender, body mass index, fasting glucose, presence of treatment at the beginning of the study and treatment with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers during the follow-up. The reduction of urinary albumin excretion was linked to the preserved glomerular filtration rate and to adequate blood pressure control.

This observational study examined the outcome of two different therapeutic strategies in the treatment of chronic neuropathic pain by including pregabalin (PGB) as mono- or add-on therapy in one of two treatment options. Patients with a pain score of > or =4, refractory to usual care for neuropathic pain for at least 6 months, were allocated consecutively to one of two treatment strategies according to the decision of the physician: complete switch to a flexible-dosage, monotherapeutic or add-on therapy with pregabalin (PGB group), or change established doses and combinations of pre-existing mono- or combination therapy without pregabalin (non-PGB group). After 4 weeks (primary endpoint) a significant improvement in pain reduction was documented in both intention-to treat (ITT) analysis (PGB group, n = 85: mean pain score reduction of 3.53, SD 2.03, p < 0.001; non-PGB group, n = 102; mean pain score reduction of 2.83, SD 2.23, p < 0.001) and per-protocol (PP) analysis (PGB group, n = 79: mean pain score reduction 3.53 vs. 2.83, p < 0.05; non-PGB group, n = 81; 3.5 vs. 2.9, p < 0.05) compared to baseline. Comparison of the results observed in the two groups shows that patients in the PGB group achieved significantly greater pain reduction. These results demonstrate that PGB administered twice daily is superior to treatment regimes without PGB in reducing pain and pain-related interference in quality of life.

Bacterial vaginosis (BV) is a common condition affecting millions of women annually and is characterised by a reduction in native lactobacilli. Antimicrobial therapy used to cure the disease is often found to be ineffective. We postulate that the potential probiotic capsule UB-01BV might be efficient in the treatment of BV. In the present study, 30 Indian women diagnosed with BV presenting symptoms such as white discharge, pH greater than 4.7, increased discharge, odour, colour of discharge and pruritus were included. All subjects were assigned to receive two potential probiotic capsules UB-01BV a day for 7 days. At the end of the treatment all subjects showed significant (P<0.001) positive response as revealed by a reduction in vaginosis symptoms. Therefore, the results of the present study provide the first preliminary evidence that the potential probiotic capsule UB-01BV can exert a significant reduction in vaginal infection.

2010-01-01

The Women’s Recovery Group study was a Stage I randomized clinical trial comparing a new manual-based group treatment for women with substance use disorders with Group Drug Counseling. Data from this study were examined to determine whether co-occurring symptoms of depression and anxiety would improve with treatment and whether these improvements would demonstrate durability over the follow-up period. The sample consisted of 36 women (29 WRG, 7 GDC) who were administered self-report and clinician-rated measures of anxiety, depression, and general psychiatric symptoms. Although there were no group differences in psychiatric symptom improvement, analyses demonstrated significant within-subject improvement in depression, anxiety, and general psychiatric symptoms. Symptom reduction was not mediated by changes in substance use. This study demonstrated significant psychiatric symptom reduction that remained durable through 6 month follow-up for women receiving group therapy focused on substance abuse relapse prevention. Reduction in psychiatric symptoms may be an additional benefit of substance abuse group therapy for women. PMID:20625473

2008-05-01

We evaluated the efficacy of loxoprofen sodium for refractory nocturia. Twelve men (mean age, 75.1 +/- 5.7) with nocturia were enrolled in this study. All patients received 60 mg loxoprofen sodium prior to sleeping at night for 14 days. Nine of 12 patients (75%) felt more satisfaction than previous treatments. Patients were grouped into a loxoprofen sodium-effective (n = 7) and ineffective groups (n = 5) based on the results of the frequency-volume chart. In the effective group, interestingly, night-time urine volume showed significant reduction (P < 0.05). On the other hand, the average single voided volume at night and 24-h urine volume showed no significant change. There was a statistically significant difference in the night-time urine volume after treatment between groups (P < 0.01). Loxoprofen sodium is an effective treatment for some patients with refractory nocturia. The main effect mechanism of loxoprofen sodium may involve the reduction of night-time urine production.

In this study, we evaluated the treatment of feline eosinophilic plaques and lip ulcers with amoxicillin trihydrate-potassium clavulanate (Clavamox(®); Pfizer Animal Health). Nineteen cats with clinical and cytological findings consistent with eosinophilic plaques and/or lip ulcers were enrolled. Lesions were photographed and their areas measured in square centimetres before and after 21 days of therapy with either flavoured amoxicillin-clavulanate suspension or flavoured placebo suspension. Sixteen cats completed the study, with nine plaque lesions (four treatment and five placebo) and eight lip ulcer lesions (four treatment and four placebo) included in the analysis. All lesions were shown to have infection, with bacterial phagocytosis present on cytological examination. Coagulase-positive staphylococci were the most commonly isolated bacteria. The amoxicillin-clavulanate-treated eosinophilic plaque group had a statistically significant 96.2% reduction in mean lesion size (-7.60 cm(2), P = 0.0078) and an 80% reduction in mean percentage of microscopic fields demonstrating evidence of bacterial infection (P < 0.0001), whereas the placebo group did not. The amoxicillin-clavulanate-treated lip ulcer group had a 42.6% decrease in mean lesion size (-0.25 cm(2), P = 0.4125) and the placebo group a 36.6% increase (+0.49 cm(2), P = 0.1575), although neither change was statistically significant. The amoxicillin-clavulanate-treated lip ulcer group had a statistically significant 65.0% reduction in mean percentage of microscopic fields demonstrating evidence of bacterial infection (P < 0.0001), while no significant reduction was observed in the placebo group. A suspension of amoxicillin trihydrate-potassium clavulanate is an effective monotherapy for the treatment of feline eosinophilic plaques. © 2011 The Authors.

Enhanced skin permeability is known to be achieved during sonophoresis due to ultrasound-induced cavitation. However, the mechanistic role of cavitation during sonophoresis has been extensively investigated only for low-frequency (LFS, <100 kHz) applications. Here, mechanisms of permeability-enhancing stable and inertial cavitation were investigated by passively monitoring subharmonic and broadband emissions arising from cavitation isolated within or external to porcine skin in vitro during intermediate- (IFS, 100-700 kHz) and high-frequency sonophoresis (HFS, >1 MHz). The electrical resistance of skin, a surrogate measure of the permeability of skin to a variety of compounds, was measured to quantify the reduction and subsequent recovery of the skin barrier during and after exposure to pulsed (1 second pulse, 20% duty cycle) 0.41 and 2.0 MHz ultrasound over a range of acoustic powers (0-21.7 W) for 30 min. During IFS, significant skin resistance reductions and acoustic emissions from cavitation were measured exclusively when cavitation was isolated outside of the skin. Time-dependent skin resistance reductions measured during IFS correlated significantly with subharmonic and broadband emission levels. During HFS, significant skin resistance reductions were accompanied by significant acoustic emissions from cavitation measured during trials that isolated cavitation activity either outside of skin or within skin. Time-dependent skin resistance reductions measured during HFS correlated significantly greater with subharmonic than with broadband emission levels. The reduction of the skin barrier due to sonophoresis was reversible in all trials; however, effects incurred during IFS recovered more slowly and persisted over a longer period of time than HFS. These results quantitatively demonstrate the significance of cavitation during sonophoresis and suggest that the mechanisms and post-treatment longevity of permeability enhancement due to IFS and HFS treatments are different.

Intravesical instillation of hyaluronic acid (HA) plus chondroitin sulfate (CS) in women with bladder pain syndrome/interstitial cystitis (BPS/IC) has shown promising results. This study compared the efficacy, safety, and costs of intravesical HA/CS (Ialuril ® , IBSA) to dimethyl sulfoxide (DMSO). Randomized, open-label, multicenter study involving 110 women with BPS/IC. The allocation ratio (HA/CS:DMSO) was 2:1. Thirteen weekly instillations of HA (1.6%)/CS (2.0%) or 50% DMSO were given. Patients were evaluated at 3 (end-of-treatment) and 6 months. Primary endpoint was reduction in pain intensity at 6 months by visual analogue scale (VAS) versus baseline. Secondary efficacy measurements were quality of life and economic analyses. A significant reduction in pain intensity was observed at 6 months in both treatment groups versus baseline (P < 0.0001) in the intention-to-treat population. Treatment with HA/CS resulted in a greater reduction in pain intensity at 6 months compared with DMSO for the per-protocol population (mean VAS reduction 44.77 ± 25.07 vs. 28.89 ± 31.14, respectively; P = 0.0186). There were no significant differences between treatment groups in secondary outcomes. At least one adverse event was reported in 14.86% and 30.56% of patients in the HA/CS and DMSO groups, respectively. There were significantly fewer treatment-related adverse events for HA/CS versus DMSO (1.35% vs. 22.22%; P = 0.001). Considering direct healthcare costs, the incremental cost-effectiveness ratio of HA/CS versus DMSO fell between 3735€/quality-adjusted life years (QALY) and 8003€/QALY. Treatment with HA/CS appears to be as effective as DMSO with a potentially more favorable safety profile. Both treatments increased health-related quality of life, while HA/CS showed a more acceptable cost-effectiveness profile. © 2016 Wiley Periodicals, Inc.

Transcutaneous electrical nerve stimulation (TENS) may provide a safe alternative to current side-effect-heavy narcotics and anti-inflammatories utilized in chronic low back pain. Therefore, we performed a meta-analysis to evaluate the efficacy of TENS for the treatment of chronic low back pain. We included randomized controlled trials (RCTs), cohort studies, and randomized crossover studies on TENS for the management of low back pain. We utilized a visual analogue scale (VAS) for pain as our primary outcome. Effectiveness of treatment was quantified using improvement in outcome scores for each study. Of the studies that met the criteria, 13 allowed for calculation of weighted mean differences in pain reduction. We used a random model effect to evaluate changes in pain produced by the intervention. Included were nine level I and four level II, encompassing 267 patients (39% male) who had a mean follow-up of seven weeks (range; 2 to 24 weeks). The mean duration of treatment was six weeks (range; 2 to 24 weeks). The standardized mean difference in pain from pre- to post-treatment for TENS was 0.844, which demonstrated significant improvement of TENS on pain reduction. When subdividing treatment duration, patients that were treated for < 5 weeks had significant effects on pain, while those treated for > 5 weeks did not. Treatment of chronic low back pain with TENS demonstrated significant pain reduction. The application of TENS may lead to less pain medication usage and should be incorporated into the treatment armamentarium for chronic low back pain.

To determine the efficacy of a complementary analgesic modality, percutaneous electrical nerve stimulation (PENS), for the treatment of chronic low back pain (CLBP) in community-dwelling older adults. Randomized, controlled clinical trial. University of Pittsburgh Pain Evaluation and Treatment Institute. Thirty-four English speaking, community-dwelling adults aged 65 and older with CLBP of at least moderate intensity experienced every day or almost every day. Subjects were randomized to receive twice-weekly PENS and physical therapy (PT) or sham PENS and physical therapy for 6 weeks. At baseline, immediately after the 6-week intervention period, and 3 months later, the primary outcome measures pain intensity and pain-related disability were assessed. The secondary outcome measures physical performance (timed chair rise, functional reach, gait speed, static and isoinertial lifting), psychosocial factors (mood, sleep, and life control), and cognitive function (measures of attention, concentration, and mental flexibility) were also collected. Subjects randomized to PENS plus PT displayed significant reductions in pain intensity measures from pre- to posttreatment (P <.001), but the sham PENS plus PT group did not (P =.94). These pain reduction effects were maintained at 3-month follow-up. Similarly, significant reductions in pain-related disability were observed at posttreatment (P =.002) for the PENS plus PT group and were maintained at follow-up, but the sham PENS plus PT group did not show reductions in pain-related disability (P =.81). Of the secondary outcome measures, psychosocial function, timed chair rise, and isoinertial lifting endurance also improved significantly at posttreatment for the PENS plus PT group, and their improvement was sustained at 3-month follow-up, but the sham PENS plus PT did not display significant changes on these measures after treatment. This preliminary study suggests that PENS may be a promising treatment modality for community-dwelling older adults with CLBP, as demonstrated by reduction in pain intensity and self-reported disability, and improvement in mood, life control, and physical performance. Larger studies with longer duration of follow-up are needed to validate these findings and support the use of PENS in clinical practice.

Statin therapy is widely used in the prevention and treatment of cardiovascular events and is associated with significant risk reductions. However, there is considerable variation in response to statin therapy both in terms of LDL cholesterol reduction and clinical outcomes. It has been hypothesized that genetic variation contributes importantly to this individual drug response. We investigated the interaction between genetic variants and pravastatin or placebo therapy on the incidence of cardiovascular events by performing a genome-wide association study in the participants of the PROspective Study of Pravastatin in the Elderly at Risk for vascular disease--PHArmacogenetic study of Statins in the Elderly at risk (PROSPER/PHASE) study (n = 5244). We did not observe genome-wide significant associations with a clinically meaningful differential cardiovascular event reduction by pravastatin therapy. In addition, SNPs with p-values lower than 1 × 10(-4) were assessed for replication in a case-only analysis within two randomized placebo controlled pravastatin trials, CARE (n = 711) and WOSCOPS (n = 522). rs7102569, on chromosome 11 near the ODZ4 gene, was replicated in the CARE study (p = 0.008), however the direction of effect was opposite. This SNP was not associated in WOSCOPS. In addition, none of the SNPs replicated significantly after correcting for multiple testing. We could not identify genetic variation that was significantly associated at genome-wide level with a clinically meaningful differential event reduction by pravastatin treatment in a large prospective study. We therefore assume that in daily practice the use of genetic characteristics to personalize pravastatin treatment to improve prevention of cardiovascular disease will be limited.

2001-03-01

The effects of two vasoactive agents (adenosine A2A agonist, CGS 21680, and adrenoceptor agonist, noradrenaline) were examined on cardiac output (CO), heart rate (HR), blood pressure (BP), mean circulatory filling pressure (Pmcf), resistance to venous return, arterial resistance, dP/dt, plasma levels of NO2-/NO3-, and inducible nitric oxide synthase (iNOS) activity in lungs ex vivo, following treatment with tumour necrosis factor-alpha (TNF-alpha; 30 microg/kg) in anaesthetized rats. Treatment with TNF-alpha produced significant reduction in CO (41+/-2%), dP/dt (26+/-3%), BP (26+/-2%) and Pmcf (27+/-4%; n=6; mean+/-SEM), but increased arterial resistance. There were no significant changes in the plasma levels of NO2-/NO3-levels over time following treatment with TNF-alpha, but there was a significant increase (approximately twofold) in the activity of the iNOS in the lungs of animals treated with TNF-alpha. Administration of CGS 21680 (1.0 microg/kg per min) significantly increased CO (44+/-6%), HR (12+/-2%), Pmcf (24+/-4%) and dP/dt (24+/-5%) in TNF-alpha-treated rats. CGS 21680 also significantly reduced arterial resistance (33+/-2%) without altering resistance to venous return in TNF-alpha-treated rats. While noradrenaline (1.0 microg/kg per min) infusion did not significantly increase CO, it did significantly increase HR (12+/-1%), BP (55+/-9%), Pmcf (47+/-5%), dP/dt (65+/-7%), resistance to venous return (64+/-20%), and arterial resistance (41+/-16%) in TNF-alpha-treated animals. The reduction in BP due to administration of TNF-alpha is the result of significant reduction in CO. Consequently, the decline in CO can be attributed to a combination of a negative inotropic effect as well as a reduction in Pmcf. It is evident that infusion with CGS 21680 could reverse the negative impact of TNF-alpha on CO by increasing dP/dt, Pmcf and HR as well as a reduction in arterial resistance. The fact that noradrenaline did not significantly increase CO in TNF-alpha-treated rats can be attributed to increased arterial resistance as well increase in resistance to venous return.

The effects of chemical, physical, and cooking treatments on the reduction of aflatoxin B1 (AFB1), B2, G1, and G2 in soybean matrix were investigated. A HPLC-FLD with a Kobra cell system was used for the quantitative analysis of aflatoxins (AFs). To decrease the level of AFs during the soaking process, the contaminated soybeans were submerged in organic acid solutions. The reduction rates of AFB1 in 1.0N citric acid, lactic acid, succinic acid, and tartaric acid for 18h were 94.1%, 92.7%, 62.0%, and 95.1%, respectively. In the case of pH and autoclave treatment, the level of AFB1 was significantly decreased during autoclaving process at pH 7.4, 9.0, and 11.1, compared with the non-autoclaved samples (p<0.05). In the case of physical treatment, the heating process at 100 and 150°C for 90min significantly decreased the level of AFB1 by 41.9% and 81.2%, respectively (p<0.05). The reduction rate of AFB1 after cooking was 97.9% for soybean milk and 33.6% for steamed soybeans. Copyright © 2015 Elsevier Ltd. All rights reserved.

National and international health agencies have recommended a significant reduction in daily intake of sodium by reducing the amount of NaCl in foods, specifically processed meats. However, sodium reduction could increase the risk of survival and growth of spoilage and pathogenic microorganisms on these products. Therefore, alternate processing technologies to improve safety of sodium reduced foods are necessary. This study examined the effects of three different salt types and concentrations on high-pressure inactivation of Listeria monocytogenes in pre-blended ground chicken formulations. Ground chicken formulated with three salt types (NaCl, KCl, CaCl2), at three concentrations (0, 1.5, 2.5%) and inoculated with a four strain cocktail of L. monocytogenes (10(8) CFU g(-1)) were subjected to four pressure treatments (0, 100, 300, 600 MPa) and two durations (60, 180 s) in an experiment with factorial design. Surviving cells were enumerated by plating on Oxford agar and analysed by factorial ANOVA. Pressure treatments at 100 or 300 MPa did not significantly (P=0.19-050) reduce L. monocytogenes populations. Neither salt type nor concentration had a significant effect on L. monocytogenes populations at these pressure levels. At 600 MPa, salt types, concentrations and duration of pressure treatment all had a significant effect on L. monocytogenes populations. Formulations with increasing concentrations of NaCl or KCl showed significantly lower reduction in L. monocytogenes, while increase in CaCl2 concentration resulted in a significantly higher L. monocytogenes reduction. For instance, increase in NaCl concentration from 0 to 1.5 or 2.5% resulted in a log reduction of 6.16, 2.49 and 1.29, respectively, when exposed to 600 MPa for 60s. In the case of CaCl2, increase from 0 to 1.5 or 2.5% resulted in a log reduction of 6.16, 7.28 and 7.47, respectively. These results demonstrate that high-pressure processing is a viable process to improve microbial safety of sodium reduced poultry products. Crown Copyright © 2015. Published by Elsevier B.V.

Forty-two Black clients referred for outpatient treatment were randomly assigned to receive existing brochures about services or a psychoeducational booklet about stigma based on experiences of Black mental health consumers. At 3-month follow-up, clients reported that both types of information were helpful; there were no significant differences between the types of information on treatment attendance. However, individuals who reported higher perceived treatment need or greater uncertainty about treatment showed greater stigma reduction from the psychoeducation. Findings indicate the need to move beyond "customer satisfaction" to evaluate educational interventions, as well as for greater understanding of differential impact of stigma reduction interventions.

We evaluated tolerability and efficacy of aripiprazole and risperidone for treatment of methamphetamine (METH) associated psychotic symptoms in China. Patients with acute METH-associated psychotic symptoms (N=42) and with Positive and Negative Syndrome Scale (PANSS) total score between 60 and 120 were randomized to aripiprazole (initial dose 5-10mg per day followed by flexible doses 5-15 mg per day) or risperidone (initial dose 2-4 mg per day followed by flexible doses 4-6 mg per day) from day 3 to 25 of inpatient hospital stay. Outcome measures included PANSS and Clinical Global Impressions-Severity of Illness scale (CGI-S), METH craving Visual Analogue Scale (VAS), Simpson Angus Scale (SAS), Barnes Assessments Akathasia Rating Scale (BARS), and self-reported adverse effects evaluated during treatment. Retention was evaluated using Kaplan-Meier survival analysis and the MIXED models procedure was used to compare the groups on measures of psychotic and extra-pyramidal symptoms. Patients in both aripiprazole and risperidone groups showed statistically significant reductions in psychotic symptomatology from baseline during treatment (p<0.001) with no statistically significant differences between the treatment groups (p=0.73 and p=0.15, respectively). Risperidone-treated patients reported significantly greater METH craving reductions (p<0.001). Overall, 71% of patients completed the entire study, but the aripiprazole group had a significantly lower retention than the risperidone group (p=0.007), primarily due to medication related adverse effects. Aripiprazole-treated patients also had significantly more akathisia (p=0.03) and agitation (p=0.02) than risperidone-treated patients. Patients in both groups who tolerated their medications and completed the entire study achieved comparable reductions of psychotic symptoms. Copyright © 2015 Elsevier Inc. All rights reserved.

Role of somatostatin and its analogues in the treatment of acute and chronic pancreatitis.

Büchler, M W; Binder, M; Friess, H

Acute pancreatitis is caused by the activation of digestive enzymes in the pancreas and a possible treatment, therefore, is the inhibition of enzyme secretion. This approach is somewhat controversial, however, as it is not clear whether pancreatic secretion continues to occur during the course of acute pancreatitis. Animal studies show an appreciable reduction of secretion in the inflamed pancreas, but studies in humans are not conclusive. The use of somatostatin or its analogue, octreotide, has been investigated in several clinical studies. A meta analysis of six individual studies in which somatostatin was given for acute pancreatitis showed that somatostatin significantly reduces mortality. A trial in patients with moderate to severe acute pancreatitis showed a lower rate (although not statistically significant) of complications in patients treated with 3 x 200 and 3 x 500 micrograms/day octreotide, compared with controls and patients receiving a lower dose of octreotide. A further study showed a significant reduction in patient controlled analgesics in patients treated with octreotide compared with controls. Pain is the important clinical symptom of chronic pancreatitis, possibly resulting from an increased intraductal pressure during secretion. The effect on pain of the inhibition of pancreatic secretion by octreotide has been investigated in two studies. One showed no significant reduction in pain after treatment with octreotide for three days. In the other, in which octreotide was used for three weeks, significantly less pain and analgesic use was recorded during octreotide treatment than during placebo. The most common complication of chronic pancreatitis is the formation of pseudocysts. There is some evidence that octreotide may be useful in their treatment. PMID:7911442

Objectives Despite advances in treatment modalities, head and neck squamous cell carcinoma (HNSCC) remains a challenge to treat with poor survival and high morbidity, necessitating a therapy with greater efficacy. EDC22 is an extracellular drug conjugate of the monoclonal antibody targeting CD147 (glycoprotein highly expressed on HNSCC cells) linked with a small drug molecule inhibitor of Na, K-ATPase. In this study, EDC22’s potential as a treatment modality for HNSCC was performed. Materials and methods HNSCC cell lines (FADU, OSC-19, Cal27, SCC-1) were cultured in vitro and proliferation and cell viability were assessed following treatment with a range of concentrations of EDC22 (0.25–5.00 μg/mL). Mice bearing HNSCC xenografts (OSC-19, SCC-1) were treated with either EDC22 (3–10 mg/kg), anti-CD147 monoclonal antibody, cisplatin (1 mg/kg) or radiation therapy (2 Gy/week) monotherapy or in combination. Results In vitro, treatment with minimal concentration of EDC22 (0.25 μg/mL) significantly decreased cellular proliferation and cell viability (p < 0.0001). In vivo, systemic treatment with EDC22 significantly decreased primary tumor growth rate in both an orthotopic mouse model (OSC-19) and a flank tumor mouse model (SCC-1) (p < 0.05). In addition, EDC22 therapy resulted in a greater reduction in tumor growth in vivo compared to radiation monotherapy (p < 0.05) and a similar reduction in tumor growth compared to cisplatin monotherapy. Combination therapy provided no significant further reduction in tumor growth relative to EDC22 monotherapy. Conclusion EDC22 is a potent inhibitor of HNSCC cell proliferation in vitro and in vivo, warranting further investigations of its clinical potential in the treatment of HNSCC. PMID:23920309

In the Periodontitis and Vascular Events (PAVE) pilot study, periodontal therapy was provided as an intervention in a secondary cardiac event prevention model through five coordinated cardiac-dental centers. Subjects were randomized to either community care or protocol provided scaling and root planing to evaluate effects on periodontal status and systemic levels of high-sensitivity C-reactive protein (hs-CRP). After 6 months, there was a significant reduction in mean probing depth and extent of 4- or 5-mm pockets. However, there were no significant differences in attachment levels, bleeding upon probing, or extent of subgingival calculus comparing subjects assigned to protocol therapy (n = 151) to those assigned to community care (n = 152). Using intent-to-treat analyses, there was no significant effect on serum hs-CRP levels at 6 months. However, 48% of the subjects randomized to community care received preventive or periodontal treatments. Secondary analyses demonstrated that consideration of any preventive or periodontal care (i.e., any treatment) compared to no treatment showed a significant reduction in the percentage of people with elevated hs-CRP (values >3 mg/l) at 6 months. However, obesity nullified the periodontal treatment effects on hs-CRP reduction. The adjusted odds ratio for hs-CRP levels >3 mg/l at 6 months for any treatment versus no treatment among non-obese individuals was 0.26 (95% confidence interval: 0.09 to 0.72), adjusting for smoking, marital status, and gender. This pilot study demonstrated the critical role of considering obesity as well as rigorous preventive and periodontal care in trials designed to reduce cardiovascular risk.

In seven patients with anismus the striated sphincter muscle complex was selectively weakened by local injection of Clostridium botulinum type A toxin. Symptom scores improved significantly and correlated with a significant reduction in the maximum voluntary and canal squeeze pressure and a significant increase in the anorectal angle on straining. Botulinum A toxin seems to be promising treatment for some patients with anismus.

Enhanced photocatalytic CO₂-reduction activity of electrospun mesoporous TiO₂ nanofibers by solvothermal treatment.

Photocatalytic reduction of CO2 into renewable hydrocarbon fuels using semiconductor photocatalysts is considered as a potential solution to the energy deficiency and greenhouse effect. In this work, mesoporous TiO2 nanofibers with high specific surface areas and abundant surface hydroxyl groups are prepared using an electrospinning strategy combined with a subsequent calcination process, followed by a solvothermal treatment. The solvothermally treated mesoporous TiO2 nanofibers exhibit excellent photocatalytic performance on CO2 reduction into hydrocarbon fuels. The significantly improved photocatalytic activity can be attributed to the enhanced CO2 adsorption capacity and the improved charge separation after solvothermal treatment. The highest activity is achieved for the sample with a 2-h solvothermal treatment, showing 6- and 25-fold higher CH4 production rate than those of TiO2 nanofibers without solvothermal treatment and P25, respectively. This work may also provide a prototype for studying the effect of solvothermal treatment on the structure and photocatalytic activity of semiconductor photocatalysts.

This research investigated the application of Bio-Amp, a commercial bio-additive for the treatment of fat, oil, and grease (FOG) in a grease trap, and evaluated potential impacts of treated effluent on downstream collection system and treatment processes. Results show that after Bio-Amp treatment, FOG deposit formation was reduced by 40%, implicating a potential reduction of sewer line blockages. Chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and total fatty acids were reduced by 39%, 33%, 56%, and 59%, respectively, which represents an overall loading reduction of 9% COD, 5% TN and 40% TP received by the treatment plant from all the dining halls. On the other hand, readily biodegradable COD fractions significantly increased, which implies a potential improvement on Bio-P removal. Overall, the results showed that application of Bio-Amp in grease trap provides potential reduction of sewer line blockages, and can also alleviate downstream treatment burden.

Hypertension is a major risk factor for vascular disease, yet blood pressure (BP) control is unsatisfactory low, partly due to side-effects. Transcutaneous electrical nerve stimulation (TENS) is well tolerated and studies have demonstrated BP reduction. In this study, we compared the BP lowering effect of 2.5 mg felodipin once daily with 30 min of bidaily low-frequency TENS in 32 adult hypertensive subjects (mean office BP 152.7/90.0 mmHg) in a randomized, crossover design. Office BP and 24-h ambulatory BP monitoring (ABPM) were performed at baseline and at the end of each 4-week treatment and washout period. Felodipin reduced office BP by 10/6 mmHg (p <0.001 respectively) and after washout BP rose to a level still significantly lower than at baseline. TENS reduced office BP by 5/1.5 mmHg (p <0.01, ns). After TENS washout, BP was further reduced and significantly lower than at baseline, but at levels similar to BP after felodipin washout and therefore reasonably caused by factors other than the treatment per se. ABPM revealed a significant systolic reduction of 3 mmHg by felodipin, but no significant changes were noted after TENS. We conclude that our study does not present any solid evidence of BP reduction of TENS.

The aim of this study was to compare the effectiveness of trigger points' management by Positional Release Therapy (PRT) and routine medical therapy in treatment of Tension Type Headache. Tension Type Headache is the most frequent headache with the basis of myofascial and trigger point disorders. PRT is an indirect technique that treats trigger points. 30 Patients with active trigger points in cervical muscles entered to the study. They were randomly assigned to PRT or medical therapy group. Headache frequency, intensity and duration and tablet count were recorded by use of a daily headache diary. Sensitivity of trigger points was assessed by numeric pain intensity and by use of a digital force gauge (FG 5020). Both groups showed significant reduction in headache frequency and duration and tablet count after treatment phase. However, the reduction of study variables was persisted only in PRT group after follow up phase. There was no significant reduction in headache intensity, neither in PRT and nor in medication group. Sensitivity of trigger points was significantly reduced. In comparison of the two study groups, there was no significant difference in headache frequency, intensity, duration and tablet count (p> 0.05). Both procedures were equally effective according to the study. Thus, PRT can be a treatment choice for patients with T.T.H.

Different studies of the treatment of trichotillomania (TTM) have used varying standards to determine the proportion of patients who obtain clinically meaningful benefits, but there is little information on the similarity of results yielded by these methods or on their comparative validity. Data from a stepped-care (Step 1: Web-based self-help; Step 2: Individual behavior therapy; N = 60) treatment study of TTM were used to evaluate 7 potential standards: complete abstinence, ≥ 25% symptom reduction, recovery of normal functioning, and clinical significance (recovery + statistically reliable change), each of the last 3 being measured by self-report (Massachusetts General Hospital Hairpulling Scale; MGH-HPS) or interview (Psychiatric Institute Trichotillomania Scale). Depending on the metric, response rates ranged from 25 to 68%. All standards were significantly associated with one another, though less strongly for the 25% symptom reduction metrics. Concurrent (with deciding to enter Step 2 treatment) and predictive (with 3-month follow-up treatment satisfaction, TTM-related impairment, quality of life, and diagnosis) validity results were variable but generally strongest for clinical significance as measured via self-report. Routine reporting of the proportion of patients who make clinically significant improvement on the MGH-HPS, supplemented by data on complete abstinence, would bolster the interpretability of TTM treatment outcome findings.

Objectives We evaluated the effects of three doses of a behavioral intervention for obesity (High dose = 24 sessions, Moderate = 16 sessions, Low = 8 sessions) compared with a nutrition education control group (Control) on binge eating. We also examined whether participants with clinically significant improvements in binge eating had better treatment adherence and weight-loss outcomes than those who did not experience clinically significant improvements in binge eating. Finally, we examined the relation of pretreatment binge eating severity to changes at six months. Methods Participants included 572 adults (female = 78.7%; baseline mean ±SD: age = 52.7 ±11.2 years, BMI = 36.4 ±3.9 kg/m2) who provided binge eating data at baseline. We evaluated binge eating severity (assessed via the Binge Eating Scale) and weight status at baseline and six months, as well as treatment adherence over six months. Results At six months, participants in the Moderate and High treatment conditions reported greater reductions in binge eating severity than participants in the Low and Control conditions, ps < .02. Participants who demonstrated improvements in binge eating severity reported greater dietary self-monitoring adherence and attained larger weight losses than those who did not experience clinically significant reductions, ps < .001. Pretreatment binge eating severity predicted less improvement in binge eating severity over six months and fewer days with dietary self-monitoring records completed, ps ≤ .002. Conclusion A moderate or high dose of behavioral weight-loss treatment may be required to produce clinically significant reductions in binge eating severity in adults with obesity. PMID:27086049

Alexandrite and diode lasers are commonly used for hair removal. To date, the available spot sizes and repetition rates are defining factors in terms of penetration depth, treatment speed, and efficacy. Still, larger treatment areas and faster systems are desirable. To compare the efficacy, tolerability, and subject satisfaction of a continuously linear-scanning 808 nm diode laser with an alexandrite 755 nm laser for axillary hair removal. A total of 31 adults with skin types I-IV received 6 treatments at 4-week intervals with a 755 nm alexandrite laser (right axilla) and a continuously linear-scanning 808 nm diode laser (left axilla). Axillary hair density was assessed using a computerized hair detection system. There was a significant reduction in axillary hair after the 6th treatment (P < 0.05) on both sides (left, 808 nm: hair clearance of 72.16%; right, 755 nm: hair clearance of 71.30%). The difference in reduction between the two lasers was not significant, but both were persistant at 18 months follow-up (left: hair clearance of 73.71%; right: hair clearance of 71.90%). Erythema and perifollicular edema were more common after alexandrite laser treatment, but all side effects were transient. While 62.50% of patients reported more pain in response to treatment with the new diode laser, all patients rated treatment with either laser tolerable. Treatment with either the alexandrite or the linear-scanning diode laser results in significant, comparable, persistent (at least 18 months) axillary hair reduction among individuals with skin types I-IV. © 2013 Wiley Periodicals, Inc.

Harm reduction approaches endeavor to assist individuals with avoiding the most detrimental consequences of risk taking behaviors, but limited research has documented the outcomes of harm reduction substance abuse treatment. In total, 211 methamphetamine-using men who have sex with men (MSM) enrolled in two outcome studies of substance abuse treatment programs that were implementing an evidence-based, cognitive-behavioral intervention (i.e., the Matrix Model) from a harm reduction perspective. Study 1 (N = 123) examined changes in self-reported substance use, Addiction Severity Index (ASI) composite scores, and HIV care indicators over a 12-month follow-up. Study 2 (N = 88) assessed changes in substance use, sexual risk taking, and HIV care indicators over a 6-month follow-up. Participants in study 1 reported reductions in cocaine/crack use as well as decreases in the ASI drug and employment composite scores. Among HIV-positive participants in study 1 (n = 75), 47 % initiated or consistently utilized anti-retroviral therapy and this was paralleled by significant increases in self-reported undetectable HIV viral load. Study 2 participants reported reductions in methamphetamine use, erectile dysfunction medication use in combination with other substances, and sexual risk-taking behavior while using methamphetamine. Participants in both studies reported concurrent increases in marijuana use. Taken together, these studies are among the first to observe that clients may reduce stimulant use and concomitant sexual risk-taking behavior during harm reduction substance abuse treatment. Randomized controlled trials are needed to examine the differential effectiveness of harm reduction and abstinence-based approaches to substance abuse treatment.

The present study examined the predictive role of increased self-reported mindfulness skills on reduced trauma-related guilt in a sample of veterans over the course of residential treatment for posttraumatic stress disorder (PTSD; N = 128). The residential treatment consisted of seven weeks of intensive cognitive processing therapy (CPT) for PTSD, as well as additional psychoeducational groups, including seven sessions on mindfulness skills. Increased mindfulness skills describing, acting with awareness, and accepting without judgment were significantly associated with reductions in trauma-related guilt over the course of treatment. Increases in the ability to act with awareness and accept without judgment were significantly associated with reductions in global guilt, R 2 = .26, guilt distress, R 2 = .23, guilt cognitions, R 2 = .23, and lack of justification, R 2 = .11. An increase in the ability to accept without judgment was the only self-reported mindfulness skill that was associated with reductions in hindsight bias, β = -.34 and wrongdoing, β = -.44. Increases in self-reported mindfulness skills explained 15.1 to 24.1% of the variance in reductions in trauma-related guilt, suggesting that mindfulness skills may play a key role in reducing the experience of trauma-related guilt during psychotherapy. Our results provide preliminary support for the use of mindfulness groups as an adjunct to traditional evidence-based treatments aimed at reducing trauma-related guilt, though this claim needs to be tested further using experimental designs.

Background: The neural correlates of suicidal ideation and its reduction after treatment are unknown. We hypothesized that increased regional cerebral glucose metabolism in the infralimbic cortex (Brodmann area 25), amygdala, and subgenual anterior cingulate cortex would be associated with suicidal ideation and its reduction after ketamine infusion. Methods: Medication-free patients (n=19) with treatment-resistant major depressive disorder underwent positron emission tomography imaging at baseline and 230 minutes after an open-label ketamine infusion (0.5mg/kg for 40 minutes). Results: Baseline suicidal ideation and regional cerebral glucose metabolism in the infralimbic cortex were significantly correlated (r=.59, P=.007); but not overall mood scores (r=−.07, P=.79). Reductions in suicidal ideation after ketamine infusion were correlated with decreased regional cerebral glucose metabolism in the infralimbic cortex (r=.54, P=.02). Metabolism in other areas of interest was not significantly correlated with suicidal ideation or depression. Conclusion: The infralimbic cortex may be implicated in suicidal ideation. PMID:25550331

The current study provides the first replication trial of Bounce Back, a school-based intervention for elementary students exposed to trauma, in a different school district and geographical area. Participants in this study were 52 1st through 4th graders (Mage = 7.76 years; 65% male) who were predominately Latino (82%). Schools were randomly assigned to immediate treatment or waitlist control. Differential treatment effects (Time × Group Interaction) were found for child-reported posttraumatic stress disorder (PTSD) and parent-reported child coping, indicating that the immediate treatment group showed greater reductions in PTSD and improvements in coping compared with the delayed group. Differential treatment effects were not significant for depression or anxiety. Significant maintenance effects were found for both child-reported PTSD and depression as well as parent-reported PTSD and coping for the immediate treatment group at follow-up. Significant treatment effects were also found in the delayed treatment group, showing reductions in child-reported PTSD, depression, and anxiety as well as parent-reported depression and coping upon receiving treatment. In conclusion, the current study suggests that Bounce Back is an effective intervention for reducing PTSD symptoms and improving coping skills, even among a sample experiencing high levels of trauma and other ongoing stressors.

To cover the microscopic tumor spread in squamous cell carcinoma of the esophagus (SCC), longitudinal margins of 3-4 cm are used for radiotherapy (RT) protocols. However, smaller margins of 2-3 cm might be reasonable when advanced diagnostic imaging is integrated into target volume delineation. Purpose of this study was to compare the dose distribution and deposition to the organs at risk (OAR) for different longitudinal margins using a DVH- and NTCP-based approach. Ten patients with SCC of the middle or lower third were retrospectively selected. Three planning target volumes (PTV) with longitudinal margins of 4 cm, 3 cm and 2 cm and an axial margin of 1.5 cm to the gross target volume (GTV) were defined for each patient. For each PTV two treatment plans with total doses of 41.4 Gy (neoadjuvant treatment) and 50.4 Gy (definite treatment) were calculated. Dose to the lungs, heart, myelon and liver were then evaluated and compared between different PTVs. When using a longitudinal margin of 3 cm instead of 4 cm, all dose parameters (Dmin, Dmean, Dmedian and V5-V35), except Dmax could be significantly reduced for the lungs. Regarding the heart, a significant reduction was seen for Dmean and V5, but not for Dmin, Dmax, Dmedian and V10-V35. When comparing a longitudinal margin of 4 cm to a longitudinal margin of 2 cm, a significant difference was calculated for Dmin, Dmean, Dmedian and V5-V35 of the lungs and for Dmax, Dmean and V5-V35 of the heart. Nevertheless, no difference was seen for median heart dose. An additional dose reduction for V10 of the heart was achieved for definite treatment plans when using a longitudinal margin of 3 cm. The NTCP-based risk of pneumonitis was significantly reduced by a margin reduction to 2 cm for neoadjuvant and definite treatment plans. Reduction of longitudinal margins from 4 cm to 3 cm can significantly reduce the dose to lungs and Dmean of the heart. Despite clinical benefit and oncologic outcome remain unclear, reduction of the longitudinal margins might provide the opportunity to reduce side effects of chemoradiation (CRT) for SCC in upcoming studies.

To clarify the microbial pathway of the N 2 O production and consumption under different fertilizers and provide theoretical basis for the reduction of N 2 O emission and rational management of fertilization in vegetable soils, we examined dynamics of N 2 O flux and isotope signatures under different fertilizer treatments in the vegetable soils of Beijing, by setting up four treatments (organic-acetylene, organic-nonacetylene, inorganic-acetylene, inorganic-nonacetylene) and using the stable isotope technique of natural N 2 O abundance. The results showed that the cumulative N 2 O emission from organic-acetylene group, organic-nonacetylene group, inorganic-acetylene group and inorganic-nonacetylene group was (374±37), (283±34), (458±36), (355±41) g·m -2 in cabbage growing season, respectively. N 2 O fluxes were significantly lower in treatments with organic fertilizer than those with inorganic fertilizer and significantly higher in acetylene group than nonacetylene group. The degree of N 2 O reduction were similar in both fertilizer treatments, and higher nitrification was found in inorganic fertilizer than organic fertilizer treatments. Acetylene only inhibited partial nitrification and partial N 2 O reduction at the peak of N 2 O emission. When the emission was reduced, N 2 O reduction could be completely suppressed. Therefore, the inorganic fertilizer might trigger nitrification and promote higher N 2 O emission. The high concentration of N 2 O could withstand that acetylene to inhibite N 2 O reduction. Hence, using organic fertilizers instead of some inorganic ones could effectively reduce N 2 O emission in vegetable soils of Beijing. The N 2 O concentration threshold should be considered when we identify N 2 O source by acetylene inhibition method.

Polycystic ovary syndrome is one of the most common endocrinopathies in young women, and it affects 6% to 8% of women in reproductive age. Hyperandrogenism is the hallmark of polycystic ovary syndrome. The aim of the present study was to evaluate the effects of orlistat on weight loss and serum androgen levels among Iranian women with polycystic ovary syndrome. The present study was carried out in the clinic of Infertility and Reproductive Health Research Center, Shahid Beheshti University of Medical Sciences, Tehran, Iran. Thirty-two patients with polycystic ovary syndrome were randomly enrolled. We measured serum androgens (Testosterone, 17α-hydroxyprogesterone, dehydroepiandrosterone and sex hormone-binding globulin) before and after 12 weeks of treatment with orlistat. We used the Rotterdam Criteria for all patients and transvaginal sonography was performed. The mean age of patients was 27.75±6.22 and the mean body mass index was 32.69±0.94 kg/m2. Comparing with baseline, treatment with orlistat resulted in a significant reduction in weight, BMI, and waist circumference (p=0.001). We also found a remarkable reduction in total testosterone levels (p>0.001). Treatment improved the sex hormone-binding globulin plasma levels, but the improvement was not statistically significant. There was no reduction in other androgen levels. This study showed a significant reduction of weight and total testosterone level - the most important androgen in polycystic ovary syndrome - after 12 weeks of treatment with orlistat. Therefore, it seems that a short course of orlistat can be useful in the management of patients with polycystic ovary syndrome.

Objective of this study was to investigate the incidence and severity of apical root resorptions (ARR) during orthodontic treatment with aligners. The sample comprised 100 patients (17-75 years of age) with a class I occlusion and anterior crowding before treatment, treated exclusively with aligners (Invisalign®, Align Technologies, Santa Clara, CA, USA). The following teeth were assessed: upper and lower anterior teeth and first molars. Root and crown lengths of a total of 1600 teeth were measured twice in pre- and post-treatment panoramic radiographs. Afterwards, relative changes of the root length during treatment were calculated by a root-crown-ratio taking pre- and post-treatment root and crown lengths into consideration. A reduction of this ratio was considered as a shortening of the initial root length. Additionally, tooth movements of the front teeth were assessed by lateral cephalograms and the 3-dimensonal set up of each patient. All patients had a reduction of the pre-treatment root length with a minimum of two teeth. On average 7.36 teeth per patient were affected. 54% of 1600 measured teeth showed no measurable root reduction. A reduction of >0%-10% of the pre-treatment root length was found in 27.75%, a distinct reduction of >10%-20% in 11.94%. 6.31% of all teeth were affected with a considerable reduction of >20%. We found no statistically significant correlation between relative root length changes and the individual tooth, gender, age or sagittal and vertical orthodontic tooth movement; except for extrusion of upper front teeth, which was considered as not clinical relevant due to the small amount of mean 4% ARR. The present study is the first analyzing ARR in patients with a fully implemented orthodontic treatment with aligners (i.e. resolving anterior crowding). The variety was high and no clinical relevant influence factor could be detected. A minimum of two teeth with a root length reduction was found in every patient. On average, 7.36 teeth per patient were affected.

The erbium-doped:yttrium, aluminum, and garnet (Er:YAG) laser is considered a useful tool for subgingival debridement because the laser treatment creates minimal damage to the root surface and has potential antimicrobial effects. The aim of this randomized controlled clinical trial was to evaluate clinical and microbiologic effects of pocket debridement using an Er:YAG laser in patients during periodontal maintenance. Twenty patients at a recall visit for maintenance were consecutively recruited if presenting at least four teeth with residual probing depth (PD) > or = 5 mm. Two pockets in each of two jaw quadrants were randomly assigned to subgingival debridement using 1) an Er:YAG laser (test) or 2) an ultrasonic scaler (control). The laser beam was set at 160 mJ with a pulse frequency of 10 Hz. Clinical variables were recorded at baseline, 1 month, and 4 months after treatment. Primary clinical outcome variables were changes in PD and clinical attachment level (CAL). Microbiologic analysis of subgingival samples was performed at baseline, 2 days, and 30 days after treatment using a checkerboard DNA-DNA hybridization technique against 12 periodontal disease-associated species. The mean initial PD was 6.0 mm (SD: 1.2) in the test group and 5.8 mm (SD: 0.9) in the control group. At 1 month post-treatment, the PD reduction was significantly greater for test than control sites (0.9 versus 0.5 mm; P <0.05). The CAL gain also was significantly greater (0.5 versus 0.06 mm; P <0.01). At the 4-month examination, no significant differences were detected in PD reduction (1.1 versus 1.0 mm) or CAL gain (0.6 versus 0.4 mm). Both treatments resulted in reduction of the subgingival microflora. No significant differences in microbiologic composition were identified between the treatment groups at various time intervals. Degree of treatment discomfort scored significantly lower for the test than the control treatment modality. The results of the trial failed to demonstrate any apparent advantage of using an Er:YAG laser for subgingival debridement, except less treatment discomfort perceived by the patients.

To preserve environmental and human health, improved treatment processes are needed to reduce nutrients, microbes, and emerging chemical contaminants from domestic wastewater prior to discharge into the environment. Electrocoagulation (EC) treatment is increasingly used to treat industrial wastewater; however, this technology has not yet been thoroughly assessed for its potential to reduce concentrations of nutrients, a variety of microbial surrogates, and personal care products found in domestic wastewater. This investigation's objective was to determine the efficiency of a benchtop EC unit with aluminum sacrificial electrodes to reduce concentrations of the aforementioned biological and chemical pollutants from raw and tertiary-treated domestic wastewater. EC treatment resulted in significant reductions (p < 0.05, α = 0.05) in phosphate, all microbial surrogates, and several personal care products from raw and tertiary-treated domestic wastewater. When wastewater was augmented with microbial surrogates representing bacterial, viral, and protozoan pathogens to measure the extent of reduction, EC treatment resulted in up to 7-log10 reduction of microbial surrogates. Future pilot and full-scale investigations are needed to optimize EC treatment for the following: reducing nitrogen species, personal care products, and energy consumption; elucidating the mechanisms behind microbial reductions; and performing life cycle analyses to determine the appropriateness of implementation.

Service performance has shown that cryogenic treatment of some metals provides improved strength, fatigue life, and wear resistance to the processed material. Effects such as these were initially discovered by NASA engineers while evaluating spacecraft that had returned from the cold vacuum of space. Factors such as high cost, poor repairability, and poor machinability are currently prohibitive for wide range use of some aerospace aluminum alloys. Application of a cryogenic treatment process to these alloys is expected provide improvements in weldability and weld properties coupled with a reduction in repairs resulting in a significant reduction in the cost to manufacture and life cycle cost of aerospace hardware. The primary purpose of this effort was to evaluate the effects of deep cryogenic treatment of some aluminum alloy plate products, welds, and weld repairs, and optimize a process for the treatment of these materials. The optimized process is being evaluated for improvements in properties of plate and welds, improvements in weldability and repairability of treated materials, and as an alternative technique for the reduction of residual stresses in repaired welds. This paper will present the results of testing and evaluation conducted in this effort. These results will include assessments of changes in strength, toughness, stress corrosion susceptability, weldability, repairability, and reduction in residual stresses of repaired welds.

Yoga may be well suited for depressed and anxious pregnant women, given reported benefits of meditation and physical activity and pregnant women's preference for nonpharmacological treatments. We randomly assigned 46 pregnant women with symptoms of depression and anxiety to an 8-week yoga intervention or treatment-as-usual (TAU) in order to examine feasibility and preliminary outcomes. Yoga was associated with high levels of credibility and satisfaction as an intervention for depression and anxiety during pregnancy. Participants in both conditions reported significant improvement in symptoms of depression and anxiety over time; and yoga was associated with significantly greater reduction in negative affect as compared to TAU (β = -0.53, SE = 0.20, p = .011). Prenatal yoga was found to be a feasible and acceptable intervention and was associated with reductions in symptoms of anxiety and depression; however, prenatal yoga only significantly outperformed TAU on reduction of negative affect.

2017-06-01

The beer-brewing process produces high amounts of nutrient-rich wastewater, and the increasing number of microbreweries worldwide has created a need for innovative solutions to deal with this waste. In the present study, fungal biomass production and the removal of organic carbon, phosphorus and nitrogen from synthetic brewery wastewater were studied. Different filamentous fungi with a record of safe use were screened for growth, and Trametes versicolor, Pleurotus ostreatus and Trichoderma harzianum were selected for further work. The highest biomass production, 1.78 ± 0.31 g L -1 of dry weight, was observed when P. ostreatus was used for the treatment, while T. harzianum demonstrated the best capability for removing nutrients. The maximum reduction of chemical oxygen demand, 89% of the initial value, was observed with this species. In the removal of total nitrogen and phosphorus, no significant difference was observed between the species, while removal of ammonium varied between the strains. The maximum reduction of ammonium, 66.1% of the initial value, was also found in the T. harzianum treatment. It can be concluded that all treatments provided significant reductions in all water-quality parameters after 3 days of growth and that the utilisation of filamentous fungi to treat brewery wastewater, linked to a deliberate strategy to use the biomass produced, has future potential in a bio-based society.

The phosphorus reduction in water column was attempted by integrating sediment microbial fuel cells (SMFCs) with the submerged macrophyte Vallisneria spiralis. A comparative study was conducted to treat simulated water rich in phosphate with a control and three treatments: SMFC alone (SMFC), submerged macrophytes alone (macophyte), and combined macrophytes and fuel cells (M-SMFC). All treatments promoted phosphorus flux from the water column to sediments. Maximum phosphorus reduction was obtained in proportion to the highest stable phosphorus level in sediments in M-SMFC. For the initial phosphate concentrations of 0.2, 1, 2, and 4 mg/L, average phosphate values in the overlying water during four phases decreased by 33.3% (25.0%, 8.3%), 30.8% (5.1%, 17.9%), 36.5% (27.8%, 15.7%), and 36.2% (0.7%, 22.1%) for M-SMFC (macrophyte, SMFC), compared with the control. With macrophyte treatment, the obvious phosphorus release from sediments was observed during the declining period. However, such phenomenon was significantly inhibited with M-SMFC. The electrogenesis bacteria achieved stronger phosphorus adsorption and assimilation was significantly enriched on the closed-circuit anodes. The higher abundance of Geobacter and Pseudomonas in M-SMFC might in part explain the highest phosphorus reduction in the water column. M-SMFC treatment could be promising to control the phosphorus in eutrophic water bodies.

Aims In diabetics, acarbose causes a reduction of blood glucose and triglyceride levels. The aim of this study was to assess the effect of this drug in non diabetic subjects with hypertriglyceridaemia. Methods Thirty non diabetic patients with hypertriglyceridaemia type IIb or IV (24 males, six females; mean age 51.1 ±10.2 years) were studied. They were stratified into two groups depending on their basal triglyceride concentration (group A: triglyceride values ≤4.5 mmol l−1; group B triglyceride values > 4.5 mmol l− 1). Treatment consisted of 4 week courses of diet plus acarbose (50 mg twice daily) alternating with 4 weeks of diet alone for a total period of 16 weeks. Results Mean triglyceride values decreased significantly during the first and third cycles of therapy, i.e. diet plus acarbose treatment cycles in both patient groups. Group A also had significant reductions in total cholesterol and HDL cholesterol concentrations after completion of the acarbose treatment. Reduction of triglyceride levels was observed after both acarbose courses in patients affected by hypertriglyceridaemia type IIb. A marked reduction of triglyceride concentrations was achieved by patients affected by hypertriglyceridaemia type IV after the second acarbose course only. Conclusions Diet alone did not reduce triglyceride concentrations to normal values in our patients. The data suggest that acarbose is a useful adjunct to dietary control in non-diabetic patients affected by severe hypertriglyceridaemia. PMID:10583032

Firearm injuries continue as a major public health problem, contributing significant morbidity, mortality, and expense to our society. There are four main steps in the management of patients with gunshot wounds to the face: securing an airway, controlling haemorrhage, identifying other injuries and definitive repair of the traumatic facial deformities. The objective of this study was to determine late outcome of two treatment options by open reduction and internal fixation versus closed reduction and maxillomandibular fixation (MMF) in the treatment of gunshot injuries of the mandible. Sixty patients of gunshot injury were randomly allocated in two groups. In group A, 30 patients were treated by open reduction and internal fixation and in group B, 30 patients were treated by closed reduction and maxillomandibular fixation. Patients were discharged as the treatment completed and recalled for follow up. Up to 3 months after injury, fortnightly complications like infection, malocclusion, malunion of fractured fragments, facial asymmetry, sequestration of bone and exposed plates were evaluated and the differences between two groups were assessed. The follow-up period ranged from 3 months to 10 months. Patients treated by open reduction tended to have less complications as compared to closed reduction. Based on this study open reduction and internal fixation is the best available method for the treatment of gunshot mandible fractures without continuity defect. Copyright © 2012 Elsevier Ltd.

This study examines the statistical and clinical significance of symptom changes during an intensive inpatient treatment program with a strong psychotherapeutic focus for individuals with severe bulimia nervosa. 295 consecutively admitted bulimic patients were administered the Structured Interview for Anorexic and Bulimic Syndromes-Self-Rating (SIAB-S), the Eating Disorder Inventory-2 (EDI-2), the Brief Symptom Inventory (BSI), and the Beck Depression Inventory-II (BDI-II) at treatment intake and discharge. Results indicated statistically significant symptom reductions with large effect sizes regarding severity of binge eating and compensatory behavior (SIAB-S), overall eating disorder symptom severity (EDI-2), overall psychopathology (BSI), and depressive symptom severity (BDI-II) even when controlling for antidepressant medication. The majority of patients showed either reliable (EDI-2: 33.7%, BSI: 34.8%, BDI-II: 18.1%) or even clinically significant symptom changes (EDI-2: 43.2%, BSI: 33.9%, BDI-II: 56.9%). Patients with clinically significant improvement were less distressed at intake and less likely to suffer from a comorbid borderline personality disorder when compared with those who did not improve to a clinically significant extent. Findings indicate that intensive psychotherapeutic inpatient treatment may be effective in about 75% of severely affected bulimic patients. For the remaining non-responding patients, inpatient treatment might be improved through an even stronger focus on the reduction of comorbid borderline personality traits.

Belief in God is very common and tied to mental health/illness in the general population, yet its relevance to psychiatric patients has not been adequately studied. We examined relationships between belief in God and treatment outcomes, and identified mediating mechanisms. We conducted a prospective study with n=159 patients in a day-treatment program at an academic psychiatric hospital. Belief in God, treatment credibility/expectancy, emotion regulation and congregational support were assessed prior to treatment. Primary outcomes were treatment response as well as degree of reduction in depression over treatment. Secondary outcomes were improvements in psychological well-being and reduction in self-harm. Belief in God was significantly higher among treatment responders than non-responders F(1,114)=4.81, p<.05. Higher levels of belief were also associated with greater reductions in depression (r=.21, p<.05) and self-harm (r=.24, p<.01), and greater improvements in psychological well-being (r=.19, p<.05) over course of treatment. Belief remained correlated with changes in depression and self-harm after controlling for age and gender. Perceived treatment credibility/expectancy, but not emotional regulation or community support, mediated relationships between belief in God and reductions in depression. No variables mediated relationships to other outcomes. Religious affiliation was also associated with treatment credibility/expectancy but not treatment outcomes. Belief in God, but not religious affiliation, was associated with better treatment outcomes. With respect to depression, this relationship was mediated by belief in the credibility of treatment and expectations for treatment gains. Copyright © 2012 Elsevier B.V. All rights reserved.

The purpose of this single-masked, randomized, controlled clinical trial was to evaluate the effects of boric acid irrigation as an adjunct to scaling and root planing (SRP) on clinical and microbiologic parameters and compare this method with chlorhexidine irrigation and SRP alone in patients with chronic periodontitis (CP). Forty-five systemically healthy patients with CP are included in this study. They were divided into three groups: 1) SRP + saline irrigation (C); 2) SRP + chlorhexidine irrigation (CHX); and 3) SRP + boric acid irrigation (B). To determine an ideal concentration of boric acid, a preclinical analysis was conducted. At baseline, 1 month, and 3 months after treatment, clinical measurements, including plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP), were performed, and subgingival plaque samples were taken. Quantitative analysis of Porphyromonas gingivalis (Pg), Tannerella forsythia (Tf), and Treponema denticola (Td) was performed using real-time polymerase chain reaction (PCR) procedures. The concentration of boric acid is 0.75% in this study. All clinical parameters showed statistically significant reduction at all time points compared to baseline in all groups (P <0.001). Whole-mouth PD and CAL reduction was similar in all groups at all time points after treatment (P >0.05). The PD and CAL reductions for moderately deep pockets (PD ≥5 and <7) were greater in the B group compared to other groups between baseline and 1 month (P <0.05). For deep pockets (PD ≥7), reductions were similar in the B and CHX groups (P >0.05). BOP (percentage) was significantly lower in the B group compared with the CHX and C groups in the first month after treatment (P <0.001). GI and PI scores were significantly lower in the B and CHX groups compared with the C group at all time points after treatment (P <0.05). The amounts of Pg, Tf, and Td were significantly reduced in all treatment groups after 1 month (P <0.05). No statistically significant differences were detected among the groups for microbiologic parameters at any time points after treatment (P >0.05). The results of this study suggest that boric acid could be an alternative to chlorhexidine, and it might be more favorable because boric acid was superior in whole-mouth BOP as well as PD and CAL reduction for moderate pockets in early time periods.

Cognitive behavioral therapy (CBT) is a well-established treatment for anxiety disorders, and evidence is accruing for the effectiveness of acceptance and commitment therapy (ACT). Little is known about factors that relate to treatment outcome overall (predictors), or who will thrive in each treatment (moderators). The goal of the current project was to test attentional bias and negative emotional reactivity as moderators and predictors of treatment outcome in a randomized controlled trial comparing CBT and ACT for social phobia. Forty-six patients received 12 sessions of CBT or ACT and were assessed for self-reported and clinician-rated symptoms at baseline, post treatment, 6, and 12 months. Attentional bias significantly moderated the relationship between treatment group and outcome with patients slow to disengage from threatening stimuli showing greater clinician-rated symptom reduction in CBT than in ACT. Negative emotional reactivity, but not positive emotional reactivity, was a significant overall predictor with patients high in negative emotional reactivity showing the greatest self-reported symptom reduction.

A comparison of the desensitising efficacy of two commercially available dentifrices with different modes of action was conducted in a randomised, examiner-blind, two-arm, parallel group, 8-week, longitudinal clinical study. Dentifrice A, (Sensodyne Multi Action Iso-Active), contained 50000 ppm KNO3 and 1450 ppm fluoride as NaF. Dentifrice B, Colgate Sensitive Pro-Relief, contained a combination of 80000 ppm arginine, bicarbonate, calcium carbonate, and 1450 ppm fluorine as NaMFP. Subjects (N = 110), stratified into two groups (N = 55), brushed twice-daily for 60 s, over an 8-week period. Sensitivity status, compliance, and safety were determined at 1, 2, 4, and 8 weeks. A fixed-effects ANCOVA statistical model was applied to the Intent-To-Treat population using a two-sided 5% significance level. After 8 weeks, the treatment groups using Dentifrice A and Dentifrice B exhibited mean reductions from baseline of 49% and 45% in air sensitivity visual analogue scale (VAS) score, 61% (both) in examiner-based Schiff Sensitivity score, and clinically significant reductions in tactile pain threshold; all reductions were statistically significant (P < 0.0001). Both treatment groups also exhibited significant reductions across all sensitivity measures at 1, 2, and 4 weeks (P ≤ 0.0059, Dentifrice A; P ≤ 0.0137, Dentifrice B). PMID:23304149

Using laboratory experiments, the authors investigated the impact of dry-heat and moist-heat treatment processes on hazardous trace elements (As, Hg, Cd, Cr, and Pb) in food waste and explored their distribution patterns for three waste components: oil, aqueous, and solid components. The results indicated that an insignificant reduction of hazardous trace elements in heat-treated waste-0.61-14.29% after moist-heat treatment and 4.53-12.25% after dry-heat treatment-and a significant reduction in hazardous trace elements (except for Hg without external addition) after centrifugal dehydration (P < 0.5). Moreover, after heat treatment, over 90% of the hazardous trace elements in the waste were detected in the aqueous and solid components, whereas only a trace amount of hazardous trace elements was detected in the oil component (<0.01%). In addition, results indicated that heat treatment process did not significantly reduce the concentration of hazardous trace elements in food waste, but the separation process for solid and aqueous components, such as centrifugal dehydration, could reduce the risk considerably. Finally, combined with the separation technology for solid and liquid components, dry-heat treatment is superior to moist-heat treatment on the removal of external water-soluble ionic hazardous trace elements. An insignificant reduction of hazardous trace elements in heat-treated waste showed that heat treatment does not reduce trace elements contamination in food waste considerably, whereas the separation process for solid and aqueous components, such as centrifugal dehydration, could reduce the risk significantly. Moreover, combined with the separation technology for solid and liquid components, dry-heat treatment is superior to moist-heat treatment for the removal of external water-soluble ionic hazardous trace elements, by exploring distribution patterns of trace elements in three waste components: oil, aqueous, and solid components.

The purpose of the analysis was to examine the temporal course of improvement in symptoms of posttraumatic stress disorder (PTSD) and substance use disorder among women in outpatient substance abuse treatment. Participants were 353 women randomly assigned to 12 sessions of either trauma-focused or health education group treatment. PTSD and substance use assessments were conducted during treatment and posttreatment at 1 week and after 3, 6, and 12 months. A continuous Markov model was fit on four defined response categories (nonresponse, substance use response, PTSD response, or global response [improvement in both PTSD and substance use]) to investigate the temporal association between improvement in PTSD and substance use symptom severity during the study's treatment phase. A generalized linear model was applied to test this relationship over the follow-up period. Subjects exhibiting nonresponse, substance use response, or global response tended to maintain original classification; subjects exhibiting PTSD response were significantly more likely to transition to global response over time, indicating maintained PTSD improvement was associated with subsequent substance use improvement. Trauma-focused treatment was significantly more effective than health education in achieving substance use improvement, but only among those who were heavy substance users at baseline and had achieved significant PTSD reductions. PTSD severity reductions were more likely to be associated with substance use improvement, with minimal evidence of substance use symptom reduction improving PTSD symptoms. Results support the self-medication model of coping with PTSD symptoms and an empirical basis for integrated interventions for improved substance use outcomes in patients with severe symptoms.

In this work, a respirometric approach, i.e., Dynamic Respiration Index (DRI), was used to predict the anaerobic biogas potential (ABP), studying 46 waste samples coming directly from MBT full-scale plants. A significant linear regression model was obtained by a jackknife approach: ABP=(34.4+/-2.5)+(0.109+/-0.003).DRI. The comparison of the model of this work with those of the previous works using a different respirometric approach (Sapromat-AT(4)), allowed obtaining similar results and carrying out direct comparison of different limits to accept treated waste in landfill, proposed in the literature. The results indicated that on an average, MBT treatment allowed 56% of ABP reduction after 4weeks of treatment, and 79% reduction after 12weeks of treatment. The obtainment of another regression model allowed transforming Sapromat-AT(4) limit in DRI units, and achieving a description of the kinetics of DRI and the corresponding ABP reductions vs. MBT treatment-time.

Favourable pain relief results on evoking autonomous twitches at myofascial trigger points with Electrical Twitch Obtaining Intramuscular Stimulation (ETOIMS). To document autonomic nervous system (ANS) dysfunction in Complex Regional Pain Syndrome (CRPS) from blood pressure (BP) and pulse/heart rate changes with ETOIMS. A patient with persistent pain regularly received serial ETOIMS sessions of 60, 90, 120 or ≥150 min over 24 months. Outcome measures include BP: systolic, diastolic, pulse pressure and pulse/heart rate, pre-session/immediate-post-session summed differences (SDPPP index), and pain reduction. His results were compared with that of two other patients and one normal control. Each individual represented the following maximal elicitable twitch forces (TWF) graded 1-5: maximum TWF2: control subject; maximum TWF3: CRPS patient with suspected ANS dysfunction; and maximum TWF4 and TWF5: two patients with respective slow-fatigue and fast-fatigue twitches who during ETOIMS had autonomous twitching at local and remote myotomes simultaneously from denervation supersensitivity. ETOIMS results between TWFs were compared using one-way analysis of variance test. The patients showed immediate significant pain reduction, BP and pulse/heart rate changes/reduction(s) except for diastolic BP in the TWF5 patient. TWF2 control subject had diastolic BP reduction with ETOIMS but not with rest. Linear regression showed TWF grade to be the most significant variable in pain reduction, more so than the number of treatments, session duration and treatment interval. TWF grade was the most important variable in significantly reducing outcome measures, especially pulse/heart rate. Unlike others, the TWF3 patient had distinctive reductions in SDPPP index. Measuring BP and pulse/heart rate is clinically practical for alerting ANS dysfunction maintained CRPS. SDPPP index (≥26) and pulse/heart rate (≥8) reductions with almost every ETOIMS treatment, plus inability to evoke autonomous twitches due to pain-induced muscle hypertonicity, are pathognomonic of this problem.

Inhalation of bacterial endotoxin induces an acute inflammation in the lower respiratory tract. In this study, the anti-inflammatory effects of the anti-oxidant N-acetylcysteine (NAC) and the glucocorticoid dexamethasone were investigated in mice exposed to aerosolized endotoxin (lipopolysaccharide (LPS)). Powerful reduction of neutrophils in bronchoalveolar lavage fluid (BALF) was obtained by a single i.p. injection of dexamethasone (10 mg/kg), whereas treatment with NAC only resulted in reduction of neutrophils when administered at a high dose (500 mg/kg). Measurement of cytokine and chemokine expression in lung tissue revealed a significant decrease of tumour necrosis factor-alpha, IL-1α, IL-1β, IL-6, IL-12p40, and MIP-1α mRNA when mice where treated with dexamethasone but not when treated with NAC. Analysis of oxidative burst demonstrated a remarkable reduction of oxygen radicals in BALF neutrophils after treatment with dexamethasone, whereas the effect of NAC was not significantly different from that in untreated animals. In conclusion, dexamethasone exerted both anti-inflammatory and anti-oxidative effects in acute airway inflammation, probably by blocking early events in the inflammatory cascade. In contrast, treatment with NAC resulted in a weak reduction of the inflammatory response but no inhibition of proinflammatory cytokines or reduction of oxidative burst in neutrophils. These results demonstrate dramatic differences in efficiency and also indicate that the two drugs have different actions. Combined treatment with NAC and dexamethasone revealed an additive action but no synergy was observed. PMID:11091282

Commercial table eggs are washed prior to packaging. Standard wash procedures use an alkaline pH and warm water. If a cool water method could be developed that would still provide a microbiologically safe egg, the industry may save energy costs associated with water heating. Four wash procedures were evaluated for Salmonella reduction: pH 11 at 48.9°C (industry standard), pH 11 at ambient temperature (∼20°C), pH 6 at 48.9°C, and pH 6 at ambient temperature. Alkaline washes contained potassium hydroxide-based detergent, while pH 6 washes contained approximately 200 ppm of chlorine and a proprietary chlorine stabilizer (T-128). When eggs were inoculated by immersion in a cell suspension of Salmonella Enteritidis and Salmonella Typhimurium, all treatments resulted in a slight and similar reduction of Salmonella numbers (approximately 0.77 log CFU/ml of shell emulsion reduction). When eggs were inoculated by droplet on the shell surface, Salmonella counts were reduced by approximately 5 log CFU when washed with chlorine plus the chlorine stabilizer at both temperatures and with the alkaline wash at the high temperature. The reductions in Salmonella by these treatments were not significantly (P > 0.05) different from each other but were significantly (P < 0.05) more than the reduction observed for the 20°C alkaline treatment and 20°C control water treatments. Ambient temperature acidic washes reduced Salmonella contamination to the same degree as the standard pH 11 warm water wash and may be a viable option to reduce cost, increase shelf life, and slow pathogen growth in and on shell eggs.

Although it is well established that people who use drugs (PWUDs) are characterized by significant neurocognitive impairment (NCI), there has been no examination of how NCI may impede one’s ability to accrue the expected HIV prevention benefits stemming from an otherwise efficacious intervention. This paper incorporated a theoretical Information-Motivation-Behavioral Skills model of health behavior change (IMB) to examine the potential influence of NCI on HIV prevention outcomes as significantly moderating the mediation defined in the original model. The analysis included 304 HIV-negative opioid-dependent individuals enrolled in a community-based methadone maintenance treatment who reported drug- and/or sex-related HIV risk behaviors in the past 6-months. Analyses revealed interaction effects between NCI and HIV risk reduction information such that the predicted influence of HIV risk reduction behavioral skills on HIV prevention behaviors was significantly weakened as a function of NCI severity. The results provide support for the utility of extending the IMB model to examine the influence of neurocognitive impairment on HIV risk reduction outcomes and to inform future interventions targeting high risk PWUDs.

Background and Objectives: Prevention of the periodontal disease progression is the primary goal of periodontal therapy. When conventional therapy is found inadequate to attain periodontal health in chronic periodontitis, local antimicrobial agents have been used as an adjunct with scaling and root planning (SRP) which has reproduced encouraging results. Hence, this study was undertaken to evaluate the new sustained released local drug Chlosite clinically and microbiologically in smokers and non-smokers. Materials and Methods: The patients were grouped into experimental group A treated with SRP plus Chlosite (SRP + CHL), experimental group B treated with Chlosite alone (CHL), and control group C treated only with SRP alone. A total number of 141 sites from six patients (67 sites from three non-smoker patients and 74 sites from three smoker patients) participated in this study. The clinical parameters, Plaque index (PI), Gingival index (GI), Bleeding index (BI), and Relative attachment level (RAL), were recorded and subgingival plaque samples were collected and subjected to microbiological analysis. Results: On comparison of smokers and non-smokers, in SRP group, non-smokers showed a higher reduction in BI and GI and smokers showed a higher reduction in PI. There was no significant gain in RAL of both smokers and non-smokers. In SRP + CHL group, non-smokers showed a higher reduction in relation to BI and GI and smokers showed a higher reduction in relation to PI. There was no significant gain in RAL of both smokers and non-smokers. In CHL group, both smokers and non-smokers showed a nonsignificant reduction in BI, GI, and RAL, but smokers showed a significant reduction in PI as compared with non-smokers. All the groups showed reduction in the microbial count of Fusobacterium nucleatum, Porphyromonas gingivalis, and Tannerella forsythia which were found to be statistically not significant when it was compared between non-smokers and smokers. Interpretation and Conclusion: In this study, all treatment groups were found to be efficacious in the treatment of periodontal disease as demonstrated by improvement in PI, GI, BI, and RAL. Combination of SRP and Chlosite resulted in added benefits compared with the two treatment groups. PMID:22028508

Clozapine is associated with significant weight gain and metabolic disturbances. This multicentre, randomized study comprised a double-blind, placebo-controlled treatment phase of 16 wk, and an open-label extension phase of 12 wk. Outpatients who met DSM-IV-TR criteria for schizophrenia, who were not optimally controlled while on stable dosage of clozapine for > or =3 months and had experienced weight gain of > or =2.5 kg while taking clozapine, were randomized (n=207) to aripiprazole at 5-15 mg/d or placebo, in addition to a stable dose of clozapine. The primary endpoint was mean change from baseline in body weight at week 16 (last observation carried forward). Secondary endpoints included clinical efficacy, body mass index (BMI) and waist circumference. A statistically significant difference in weight loss was reported for aripiprazole vs. placebo (-2.53 kg vs. -0.38 kg, respectively, difference=-2.15 kg, p<0.001). Aripiprazole-treated patients also showed BMI (median reduction 0.8 kg/m(2)) and waist circumference reduction (median reduction 2.0 cm) vs. placebo (no change in either parameter, p<0.001 and p=0.001, respectively). Aripiprazole-treated patients had significantly greater reductions in total and low-density lipoprotein (LDL) cholesterol. There were no significant differences in Positive and Negative Syndrome Scale total score changes between groups but Clinical Global Impression Improvement and Investigator's Assessment Questionnaire scores favoured aripiprazole over placebo. Safety and tolerability were generally comparable between groups. Combining aripiprazole and clozapine resulted in significant weight, BMI and fasting cholesterol benefits to patients suboptimally treated with clozapine. Improvements may reduce metabolic risk factors associated with clozapine treatment.

The present study examined the efficacy of virtual reality (VR) exposure therapy for treating individuals with storm fears by comparing a one-session VR exposure treatment with a one-session progressive muscle relaxation (PMR) and psychoeducation session. It was predicted that there would be a reduction in storm-related fear post-treatment for individuals in both conditions, but that this reduction would be greater for those in the VR exposure condition. It was predicted that improvements would be maintained at 30-day follow-up only for those in the VR exposure condition. Thirty-six participants each received one of the two treatment conditions. Those in the PMR treatment group received approximately 30 minutes of PMR and approximately 15 minutes of psychoeducation regarding storms. Those in the VR treatment group received approximately 1 hour of VR exposure. Additionally, participants were asked to complete a pre-treatment and post-treatment 5-minute behavioural approach test to assess changes in storm fears. They were also asked to complete a measure assessing storm phobia. There was a significant interaction between treatment group and self-reported fear at post-treatment, such that fear decreased for both groups, although the reduction was stronger in the VR group. Results also showed that reductions in storm fear were maintained at 30-day follow-up for both groups. Although this study used a small non-clinical sample, these results offer preliminary support for the use of VR exposure therapy in the treatment of storm-related fear.

The objective of this study was a comparison of the prognosis between an extracorporeal reduction technique and closed treatment of a mandibular condyle fracture. The relationship between condylar resorption and several clinical variables was also studied. Seventy-one patients who had a mandibular condyle fracture took part in this study. Thirty-five patients (female: 7, male: 28, age: 30.46 ± 14.27 years) were treated by extracorporeal reduction, and 36 patients (male: 24, female: 12, age: 24.28 ± 9.99 years) were treated using a closed treatment. The presence of complications such as condylar resorption, malocclusion, nerve disorder, and disc displacement was evaluated with panoramic radiographs and clinical examinations 12 months after treatment. The relationships between the complications and other clinical variables were evaluated statistically. The anatomic site and fracture type were closely related to condyle resorption in the bivariate analysis. Condylar head fractures showed significantly higher condyle resorption than condylar neck fractures (P = .023). A complex or compound fracture showed significantly higher condyle resorption compared with a simple fracture (P = .006). Patients who had a complex/compound fracture were 34.366 times more likely to have condyle resorption compared with those who had a simple fracture (P = .002). The patient's age and treatment method were also significant predictors for condyle resorption. Fracture type was the strongest predictor of condylar resorption. Because treatment method and patient age were also related to the prognosis, the optimal treatment for mandibular condylar head and/or neck fractures should be individualized according to the patient's condition.

Small, A; Wells-Burr, B; Buncic, S

2005-02-01

The effectiveness of different decontamination treatments in reducing microbial loads on cattle hides was assessed. The 10-s hide treatments were conducted using a wet-and-dry vacuum cleaner filled with one of the liquids (heated to 50 °C) indicated below, followed or not by 10-min drying in the air. Also, the hide was clipped, followed or not by 10-s singeing using a hand-held blowtorch. Before and after each decontamination treatment, the hide was sampled (100 cm(2) areas) by a sponge-swabbing method to compare the total viable counts of bacteria (TVC). The largest bacterial reduction (P<0.001; 2.31log(10) cfu/cm(2)) was achieved by singeing of previously clipped hide. Treatment of hide with a food industry sanitizer solution (10% Betane Plus) resulted in significant reductions of 1.80 (P<0.001) and 1.98log(10) cfu/cm(2) (P<0.001) without and with subsequent drying, respectively. Treatment of hide with a food industry disinfectant (P3-Topactive DES) significantly reduced TVC by 0.97 (P<0.001) and 1.18log(10) cfu/cm(2) (P<0.001) without and with subsequent drying, respectively. Treatments of hide with water alone or with a food-safe detergent solution (Formula 963B), or hide clipping alone, did not produce significant decontamination effects. Since hide contamination is associated with microbial contamination of the carcasses, the results indicate that post-killing/pre-skinning hide decontamination (used alone, or in combination with carcass decontamination) has a potential to improve microbial meat safety. Nevertheless, further research is required to optimise the efficacy of these treatments in the reduction of specific pathogens under commercial conditions.

Treatments offered at the Maharishi Ayurveda Health Centre in Norway are based on Maharishi Vedic Medicine (MVM). MVM is a consciousness-based revival by Maharishi Mahesh Yogi, the founder of the Transcendental Meditation (TM) program of the ancient Ayurvedic medicine tradition in India. To extend from 6 to 24 months, a pilot study of the effects of the treatment program at the Health Centre on fibromyalgia. Retesting 2 years after a clinical trial. In this intention to treat study, 31 women with a diagnosis of fibromyalgia received an individually tailored program of (1) physiological purification therapy (Maharishi Panchakarma) and (2) Ayurvedic recommendations regarding daily routine and diet including a novel approach to food intolerance. Five subjects chose to learn TM for stress reduction, pain management and personal development. All were recommended Ayurvedic herbal products for follow-up treatment. A modified Fibromyalgia Impact Questionnaire (FIQ) that included seven dimensions. Scores at 24 months follow-up were compared with pre-treatment scores. At 24-months follow-up, there were significant reductions (26% to 44%) in six of the seven fibromyalgia dimensions: impairment of working ability, pain, tiredness, morning tiredness, stiffness and anxiety. The 7th, depression, decreased 32% (borderline significant). At 24 months, the four subjects who continued practising TM, had almost no symptoms and significantly lower FIQ change scores (-92% to 97%) than the non-meditators on all outcomes. This pilot study suggests that the treatments and health promotion programs offered at the Maharishi Ayurveda Health Centre in Norway lead to long-term reductions in symptoms of fibromyalgia, which is considered a treatment-resistant condition, and further studies are warranted.

The primary objective of this study was to determine whether contingency management was associated with increased abstinence from stimulant drug use in stimulant-dependent patients with serious mental illness treated in a community mental health center. Secondary objectives were to determine whether contingency management was associated with reductions in use of other substances, psychiatric symptoms, HIV risk behavior, and inpatient service utilization. A randomized controlled design was used to compare outcomes of 176 outpatients with serious mental illness and stimulant dependence. Participants were randomly assigned to receive 3 months of contingency management for stimulant abstinence plus treatment as usual or treatment as usual with reinforcement for study participation only. Urine drug tests and self report, clinician-report, and service utilization outcomes were assessed during the 3-month treatment period and the 3-month follow-up period. Although participants in the contingency management condition were significantly less likely to complete the treatment period than those assigned to the control condition (42% compared with 65%), they were 2.4 times (95% CI=1.9–3.0)more likely to submit a stimulant-negative urine test during treatment. Compared with participants in the control condition,they had significantly lower levels of alcohol use, injection drug use, and psychiatric symptoms and were one-fifth as likely as those assigned to the control condition to be admitted for psychiatric hospitalization during treatment. They also reported significantly fewer days of stimulant drug use during the 3-month follow-up. When added to treatment as usual, contingency management is associated with large reductions in stimulant,injection drug, and alcohol use.Reductions in psychiatric symptoms and hospitalizations are important secondary benefits.

To analyze the importance of the starting time for pelvic floor physiotherapy in patients with post radical prostatectomy urinary incontinence. Between May 2003 and February 2004 18 patients with the diagnosis of post radical prostatectomy urinary incontinence underwent physiotherapy of the pelvic floor. Each patient received 12 sessions using kinesotherapy and electric stimulation on a weekly basis. Patients were divided into two groups: Group 1 included eight patients that started therapy within the first six months after surgery; Group 2 included 10 patients starting therapy after the sixth post operative month. All patients were evaluated by the pad test and number of incontinence pads per day. Evaluating pad tests before and after treatment, six patients in group 1 had a reduction of the amount of urine leak in comparison to seven patients in group 2. The statistical analysis showed significant differences before and after treatment for both groups (group 1: p = 0.028; group 2: p = 0.018). The evaluation of the number of pads showed: Group 1: all eight patients using pods had a reduction in the number of pads. Group 2: 5 of the eight patients using pads had a reduction and the other three continued using the same number. Statistical analysis comparing the number of pads per day before and after treatment showed a significant difference in group 1 (p = 0.004). There was no statistically significant difference in the number of pads per day before and after physiotherapy in group 2, although half of the patients showed a diminishment in the number of pads required after treatment. Results demonstrate that early indication of physiotherapy for the treatment of post radical prostatectomy urinary incontinence is better than delayed treatment. New works may be developed in the future to confirm our results.

To compare open reduction and internal fixation (ORIF) and non-surgical treatment outcomes in displaced midshaft clavicle fractures. PubMed, MEDLINE, EMBASE, Web of Science, Cochrane Library, and ClinicalTrials.gov were searched in September 2017. Inclusion criteria were randomized controlled trials reporting nonunion, shoulder functional outcomes, and subsequent surgery rates or pain scores. We excluded studies with patients younger than 16 years, maximum follow-up less than nine months, and inaccessible full text. Extracted data included the first author, publication year, number of patients, number of nonunions, Constant scores, disabilities of the arm, shoulder and hand (DASH) scores, number of subsequent surgeries, and pain measured using the visual analogue analog scale. The risk ratio (RR) of nonunion was 0.15 (95% confidence interval [CI], 0.08, 0.31) in ORIF compared with that of non-surgical treatment. Constant and DASH scores were significantly better in ORIF up to 6 months. The mean difference (MD) in DASH scores at 12 months was statistically insignificant in both treatments (MD, -4.19; 95% CI, -9.34, 0.96). Constant scores remained significant in ORIF (MD, 4.39; 95% CI, 1.03, 7.75). Subsequent surgeries and pain scores were similar in both treatments. Significant reduction in nonunions and favorable early functional outcomes are associated with ORIF. Nevertheless, late functional outcomes, subsequent surgeries, and pain scores are similar to those of non-surgical treatment. Although patients treated with ORIF mainly had subsequent elective plate removals; non-surgically treated patients had more surgical fixations for nonunions. As a result, there remains inconsistent evidence regarding the best treatment for displaced midshaft clavicle fractures. Therapeutic Level I.

The aim of this study was to evaluate the effects of non-surgical periodontal therapy on intra-oral halitosis 3 months after therapy. Sixty-eight adults with intra-oral halitosis were included in a case series. Intra-oral halitosis was evaluated at baseline, and at 3 months after treatment using the organoleptic scores (OLS), Halimeter ® , and a gas chromatograph. Significant reductions for OLS (p < 0.01), total sum of volatile sulphur compounds (T-VSC) (p < 0.01) and methyl mercaptan (MM) (p < 0.05) values were found after treatment. Hydrogen sulphide (H 2 S) levels were not significantly reduced. The numbers of probing pockets 4 mm, 5 mm and 6 mm were significantly reduced as a result of therapy (p < 0.001). Bleeding on probing (BOP) and plaque indices were also significantly reduced (p < 0.001). For the 34 individuals with successful periodontal treatment (BOP<20% and a ≥50% reduction of total pocket depth) reductions in OLS (p < 0.01) and T-VSC scores (p < 0.01) were found. Eleven individuals were considered effectively treated for intra-oral halitosis presenting with a T-VSC value <160 ppb, a H 2 S value <112 ppb and a MM value <26 ppb. Non-surgical periodontal therapy resulted in reduction of OLS, MM and T-VSC values 3 months after therapy. Few individuals were considered as effectively treated for intra-oral halitosis. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

In women with primary dysmenorrhoea, what is the effect of physiotherapeutic interventions compared to control (either no treatment or placebo/sham) on pain and quality of life? Systematic review of randomised trials with meta-analysis. Women with primary dysmenorrhea. Any form of physiotherapy treatment. The primary outcome was menstrual pain intensity and the secondary outcome was quality of life. The search yielded 222 citations. Of these, 11 were eligible randomised trials and were included in the review. Meta-analysis revealed statistically significant reductions in pain severity on a 0-10 scale from acupuncture (weighted mean difference 2.3, 95% CI 1.6 to 2.9) and acupressure (weighted mean difference 1.4, 95% CI 0.8 to 1.9), when compared to a control group receiving no treatment. However, these are likely to be placebo effects because when the control groups in acupuncture/acupressure trials received a sham instead of no treatment, pain severity did not significantly differ between the groups. Significant reductions in pain intensity on a 0-10 scale were noted in individual trials of heat (by 1.8, 95% CI 0.9 to 2.7), transcutaneous electrical nerve stimulation (2.3, 95% CI 0.03 to 4.2), and yoga (3.2, 95% CI 2.2 to 4.2). Meta-analysis of two trials of spinal manipulation showed no significant reduction in pain. None of the included studies measured quality of life. Physiotherapists could consider using heat, transcutaneous electrical nerve stimulation, and yoga in the management of primary dysmenorrhea. While benefits were also identified for acupuncture and acupressure in no-treatment controlled trials, the absence of significant effects in sham-controlled trials suggests these effects are mainly attributable to placebo effects.

2006-01-01

A novel sludge disintegration system (JFE-SD system) was developed for the reduction of excess sludge production in wastewater treatment plants. Chemical and biological treatments were applied to disintegrate excess sludge. At the first step, to enhance biological disintegration, the sludge was pretreated with alkali. At the second step, the sludge was disintegrated by biological treatment. Many kinds of sludge degrading microorganisms integrated the sludge. The efficiency of the new sludge disintegration system was confirmed in a full-scale experiment. The JFE-SD system reduced excess sludge production by approximately 50% during the experimental period. The quality of effluent was kept at quite a good level. Economic analysis revealed that this system could significantly decrease the excess sludge treatment cost.

Demand for nonsurgical esthetic body procedures has led to the development of noninvasive techniques for reducing localized subcutaneous adipose tissue. This study assessed multiple treatments with nonthermal focused ultrasound for noninvasive abdominal treatment of excess fat deposits. Subjects were randomly assigned to Group 1 for a 4-week control phase before undergoing 3 abdominal fat reduction treatments, at 2-week intervals, or to Group 2 for immediate treatment. Weight, abdominal circumference, tolerability to treatment, subject satisfaction, and adverse events were recorded. Weight remained stable in the 126 participants. Mean reduction in midline circumference was 2.5 ± 2.1 cm in the Group 1 and 3.5 ± 2.7 cm in the Group 2 at Week 22. The effect of multiple treatments was cumulative with a steady decrease in abdominal circumferences during the study. Erythema was observed in 28% of treatments but was mild and transient in nature. Subjects tolerated the treatments well and were satisfied with treatment outcome. The study demonstrated the efficacy and safety of multiple nonthermal focused ultrasound treatments of excess abdominal fat deposits. Although the remodeling effect is minor compared with traditional surgical procedures, successive focused ultrasound treatments significantly reduced treatment area circumference, while avoiding invasive techniques and their associated disadvantages.

Long-term Comparison of a Large Spot Vacuum Assisted Handpiece vs the Small Spot Size Traditional Handpiece of the 800 nm Diode Laser.

BACKGROUND The 800 nm long-pulsed diode laser machine is safe and effective for permanent hair reduction. Traditionally, most long-pulsed diode lasers used for hair removal had a relatively small spot size. Recently, a long-pulsed diode laser with a large spot size and vacuum assisted suction handpiece was introduced. The treatment parameters of each type of handpiece differ. Short and long-term clinical efficacy, treatment associated pain, and patient satisfaction are important factors to be considered. This study aims to conduct a direct head to head comparison of both handpieces of the 800nm long-pulsed diode laser by evaluating long term hair reduction, treatment associated pain and patient satisfaction. Thirteen subjects were enrolled in this prospective, self-controlled, single-center study of axillary laser hair removal. The study involved 4 treatments using a long pulsed diode laser with a large spot size HS handpiece (single pass), HS handpiece (double pass), and a small spot size ET handpiece according to a randomized choice. The treatment sessions were done at 4-8 week intervals with follow up visits taken at 6 and 12 months after the last treatment session. Hair clearance and thickness analysis were assessed using macro hair count photographs taken at baseline visit, at each treatment session visit and at follow up visits. Other factors including pain, treatment duration, and patients' preference were secondary study endpoints. At 6 months follow up visits after receiving four laser treatments, there was statistically significant hair clearance in the three treatment arms with 66.1 % mean percentage hair reduction with the ET handpiece, 43.6% with the HSS (single pass) and 64.1 % with the HSD (double). However, at one year follow up, the results significantly varied from the 6 months follow up. The mean percentage hair reduction was 57.8% with the ET handpiece treated axillas (n=9), 16.5% with the HSS (single pass) handpiece treated axillas (n=7), and 46.9% with the HSD (double pass) handpiece treated axillas (n=6). Thus, at one year follow up, there was a significant hair reduction that was similar in both the ET and HSD treated axillae (57.8% and 46.9 %), but only minimal hair reduction (16.5%)was observed in the HSS treated axillae. This is the first study that compared the long-term efficacy of the ET and HS handpieces after four treatment sessions with up to 12 months follow up after the last treatment session. It is also the first study that provided head to head comparison between HS (double pass), HS (single pass), and ET handpiece taking into consideration the end hair reduction result, the time consumed, the pain score experienced, and the overall patient satisfaction. HSD had better hair clearance and patient satisfaction when compared to ET and HSS. The long term follow up results showed that ET was superior to HSS (P less than .05), but was not superior to HSD (P greater than 0.05). However, HSD treated patients had lower pain scores with HSD than with ET. We conclude that ET handpiece is almost as efficacious as HSD handpiece, and the desired end results could be achieved with HDD with better patient satisfaction, less treatment duration and less pain.

The immunopathogenic mechanisms of dry eye disease (DED), one of the most common ophthalmic conditions, is incompletely understood. Data from this prospective, double-masked, randomized trial demonstrate that targeting interleukin 1 (IL-1) by topical application of an IL-1 antagonist is efficacious in significantly reducing DED-related patient symptoms and corneal epitheliopathy. To evaluate the safety and efficacy of treatment with the topical IL-1 receptor antagonist anakinra (Kineret; Amgen Inc) in patients having DED associated with meibomian gland dysfunction. Prospective phase 1/2, randomized, double-masked, vehicle-controlled clinical trial. Seventy-five patients with refractory DED. Participants were randomized to receive treatment with topical anakinra, 2.5% (n = 30), anakinra, 5% (n = 15), or vehicle (1% carboxymethylcellulose) (n = 30) 3 times daily for 12 weeks. Primary outcomes were corneal fluorescein staining (CFS), complete bilateral CFS clearance, dry eye-related symptoms as measured by the Ocular Surface Disease Index, tear film breakup time, and meibomian gland secretion quality. Topical anakinra was well tolerated compared with vehicle, with no reports of serious adverse reactions attributable to the therapy. After 12 weeks of therapy, participants treated with anakinra, 2.5%, achieved a 46% reduction in their mean CFS score (P = .12 compared with vehicle and P < .001 compared with baseline); participants treated with anakinra, 5%, achieved a 17% reduction in their mean CFS score (P = .88 compared with vehicle and P = .33 compared with baseline); and patients treated with vehicle achieved a 19% reduction in their mean CFS score (P = .11). Complete bilateral CFS clearance was noted in 8 of 28 patients (29%) treated with anakinra, 2.5%, vs in 2 of 29 patients (7%) treated with vehicle (P = .03). By week 12, treatment with anakinra, 2.5%, and treatment with anakinra, 5%, led to significant reductions in symptoms of 30% and 35%, respectively (P = .02 and P = .01, respectively, compared with vehicle); treatment with vehicle led to a 5% reduction in symptoms. Treatment with topical anakinra, 2.5%, for 12 weeks was safe and significantly reduced symptoms and corneal epitheliopathy in patients with DED. These data suggest that the use of an IL-1 antagonist may have a role as a novel therapeutic option for patients with DED. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT00681109.

Inguinal pain after groin hernia repair is a challenging issue. About 50 % of postherniorrhaphy pain allegedly is neuropathic, treatment of which is cumbersome given the limited efficacy of current therapeutic modalities. Possibly a clear protocol assessing the type of pain and treating it accordingly could improve its treatment. A prospective study was done to evaluate an algorithm in patients with chronic postherniorrhaphy groin pain, aiming to select those with neuropathic pain and to treat appropriately. Treatment consisted of ultrasound-guided nerve blocks as an initial treatment for neuropathic pain. If long-term pain reduction proved inadequate, peripheral nerve stimulation was offered. After our diagnostic workup consisting of anamnesis, physical examination and imaging, 68 patients out of 105 were diagnosed as having non-neuropathic pain. These patients were referred to the most appropriate consultant, treated accordingly or sometimes pain appeared to be self-limiting. Thirty-seven (35 %) patients were diagnosed as having neuropathic pain with a median NRS of 7 (range 4-9) and were referred for further treatment to our pain clinic. The majority (21 of 28 patients) suffered ileo-inguinal nerve involvement. After ultrasound-guided nerve blocks, a permanent reduction in pain was achieved in 18 patients (62 %) with a median post-treatment NRS of 1 (range 0-3). In six patients to which an additional peripheral nerve stimulator (PNS) was offered, pain reduction to a level of mild complaints with a median NRS of 2 (range 1-8) was observed. In total, 24 of the 28 patients (83 %) diagnosed with neuropathic postherniorrhaphy pain achieved significant pain reduction after algorithm-based treatment. In the present study, we implemented a diagnostic workup for patients with postherniorrhaphy inguinal pain to select those with neuropathic pain. Eighty-three percent of the patients with neuropathic groin pain obtained significant improvement of their pain scores after our protocolled treatment. The effect was achieved by nerve infiltrations and in some cases by an implanted PNS when the former was unsuccessful.

In the last decade, energy-based aesthetic treatments, using light, radiofrequency (RF), and ultrasound, have gained scientific acceptance as safe and efficacious for non-invasive treatment for aesthetic skin disorders. The phase-controlled multisource radiofrequency technology (3DEEP™), which is based on the simultaneous use of multiple RF generators, was proven to allow significant pigment-independent dermal heating without pain or the need of epidermal cooling. This study was performed in order to evaluate the efficacy and safety of a new handheld device delivering multisource radiofrequency to the skin for wrinkle reduction and skin tightening in the home setting. A total of 69 participants (age 54.3 years ± 8.09; age range 37-72 years) were enrolled in the study after meeting all inclusion/exclusion criteria (100%) and providing informed consent. Participants were provided with the tested device together with a user manual and treatment diary, to perform independent treatments at home for 4 weeks. The tested device, (Newa™, EndyMed Medical, Cesarea, Israel) emits 12 W of 1Mhz, RF energy through six electrodes arranged in a linear fashion. Independent control of RF polarity through each one of the 6 electrodes allows significant reduction of energy flow through the epidermis with increased dermal penetration. Participants were instructed to perform at least 5 treatments a week, for one month. Four follow-up visits were scheduled (once a week) during the period of independent treatments at home, following 4 weeks of home treatments, 1 month follow-up visit (1 month after treatment end) and at 3 months follow-up (3 months following treatment end). Analysis of pre-and post treatment images was conducted by three uninvolved physicians experienced with the Fitzpatrick Wrinkle and Elastosis Scale. Fitzpatrick Wrinkle and Elastosis score of each time point (4 weeks following home use treatments; 1 month follow-up, 3 months follow-up) was compared to baseline. Participants were asked a series of questions designed to explore usability concerns and level of satisfaction regarding the device use and subjective efficacy. Altogether, 62 subjects completed the study course and follow-up visits. No unexpected adverse effects were detected or reported throughout the independent treatment. All study participants did not experience any difficulties while operating the tested device for independent wrinkle reduction treatments. Photographic analysis of pre- and post-one month of independent home use treatments, and one and three months follow-up after end of treatment course, was conducted by three uninvolved board certified dermatologists. Analysis of results revealed improvement (downgrade of at least 1 score according to the Fitzpatrick scale) in 91.93%, 96.77%, and 98.39% of study subjects (according to the first, second, and third reviewer, respectively). Results were found to be statistically significant. The majority of study participants were very satisfied from the results of the independent treatment using the tested device for wrinkle reduction.

The impact of early symptom change and therapeutic alliance on treatment outcome in cognitive-behavioural therapy for eating disorders.

2015-10-01

The present study explored the impact of early symptom change (cognitive and behavioural) and the early therapeutic alliance on treatment outcome in cognitive-behavioural therapy (CBT) for the eating disorders. Participants were 94 adults with diagnosed eating disorders who completed a course of CBT in an out-patient community eating disorders service in the UK. Patients completed a measure of eating disorder psychopathology at the start of treatment, following the 6th session and at the end of treatment. They also completed a measure of therapeutic alliance following the 6th session. Greater early reduction in dietary restraint and eating concerns, and smaller levels of change in shape concern, significantly predicted later reduction in global eating pathology. The early therapeutic alliance was strong across the three domains of tasks, goals and bond. Early symptom reduction was a stronger predictor of later reduction in eating pathology than early therapeutic alliance. The early therapeutic alliance did not mediate the relationship between early symptom reduction and later reduction in global eating pathology. Instead, greater early symptom reduction predicted a strong early therapeutic alliance. Early clinical change was the strongest predictor of treatment outcome and this also facilitated the development of a strong early alliance. Clinicians should be encouraged to deliver all aspects of evidence-based CBT, including behavioural change. The findings suggest that this will have a positive impact on both the early therapeutic alliance and later change in eating pathology. Copyright © 2015 Elsevier Ltd. All rights reserved.

Changes in intolerance of uncertainty during cognitive behavior group therapy for social phobia.

Mahoney, Alison E J; McEvoy, Peter M

2012-06-01

Recent research suggests that intolerance of uncertainty (IU), most commonly associated with generalized anxiety disorder, also contributes to symptoms of social phobia. This study examines the relationship between IU and social anxiety symptoms across treatment. Changes in IU, social anxiety symptoms, and depression symptoms were examined following cognitive behavior group therapy (CBGT) for social phobia (N=32). CBGT led to significant improvements in symptoms of social anxiety and depression, as well as reductions in IU. Reductions in IU were associated with reductions in social anxiety but were unrelated to improvements in depression symptoms. Reductions in IU were predictive of post-treatment social phobia symptoms after controlling for pre-treatment social phobia symptoms and changes in depression symptoms following treatment. The relationship between IU and social anxiety requires further examination within experimental and longitudinal designs, and needs to take into account additional constructs that are thought to maintain social phobia. Current findings suggest that the enhancing tolerance of uncertainty may play a role in the optimal management of social phobia. Theoretical and clinical implications are discussed.

Salmonella control in animal feed is important in order to protect animal and public health. Organic acids is one of the control measures used for treatment of Salmonella contaminated feed or feed ingredients. In the present study, the efficacy of formic acid (FA) and different blends of FA, propionic acid (PA) and sodium formate (SF) was investigated. Four Salmonella strains isolated from feed were assayed for their acid tolerance. Also, the effect of lower temperatures (5°C and 15°C) compared to room temperature was investigated in rape seed and soybean meal. The efficacy of acid treatments varied significantly between different feed materials. The strongest reduction was seen in pelleted and compound mash feed (2.5 log10 reduction) followed by rapeseed meal (1 log10 reduction) after 5 days exposure. However, in soybean meal the acid effects were limited (less than 0.5 log10 reduction) even after several weeks' exposure. In all experiments the survival curves showed a concave shape, with a fast initial death phase followed by reduction at a slower rate during the remaining time of the experiment.No difference in Salmonella reduction was observed between FA and a blend of FA and PA, whereas a commercial blend of FA and SF (Amasil) was slightly more efficacious (0.5-1 log10 reduction) than a blend of FA and PA (Luprocid) in compound mash feed. The Salmonella Infantis strain was found to be the most acid tolerant strain followed by, S. Putten, S. Senftenberg and S. Typhimurium. The tolerance of the S. Infantis strain compared with the S. Typhimurium strain was statistically significant (p<0.05). The lethal effect of FA on the S. Typhimurium strain and the S. Infantis strain was lower at 5°C and 15°C compared to room temperatures. Acid treatment of Salmonella in feed is a matter of reducing the number of viable bacterial cells rather than eliminating the organism. Recommendations on the use of acids for controlling Salmonella in feed should take into account the relative efficacy of acid treatment in different feed materials, the variation in acid tolerance between different Salmonella strains, and the treatment temperature.

The aim of the present study was to compare the effect of systemically administered lycopene (LycoRed) as a monotherapy and as an adjunct to scaling and root planing in gingivitis patients. Twenty systemically healthy patients showing clinical signs of gingivitis were involved in a randomised, double-blind, parallel, split-mouth study. The subjects were randomly distributed between the two treatment groups: experimental group (n = 10), 8 mg lycopene/day for 2 weeks; and controls (n = 10), placebo for 2 weeks. Quadrant allocation within each group was randomised with two quadrants treated with oral prophylaxis (OP) and two quadrants not receiving any form of treatment (non-OP). Bleeding index (SBI) and non-invasive measures of plaque (PI) and gingivitis (GI) were assessed at baseline, 1 and 2 weeks. Salivary uric acid levels were also measured. All the treatment groups demonstrated statistically significant reductions in the GI, SBI and PI. Treatment with OP-lycopene resulted in a statistically significant decrease in GI when compared with OP-placebo (p < 0.05) and non-OP-placebo (p < 0.01). Treatment with non-OP-lycopene resulted in a statistically significant decrease in GI when compared with non-OP-placebo (p < 0.01). The OP-lycopene group showed a statistically significant reduction in SBI values when compared with the non-OP-lycopene group (p < 0.05) and the non-OP-placebo group (p < 0.001). There was a strong negative correlation between the salivary uric acid levels and the percentage reduction in GI at 1 and 2 weeks in the OP-lycopene group (r = -0.852 and -0.802 respectively) and in the non-OP-lycopene group (r = -0.640 and -0.580 respectively). The results presented in this study suggest that lycopene shows great promise as a treatment modality in gingivitis. The possibility of obtaining an additive effect by combining routine oral prophylaxis with lycopene is also an exciting possibility, which deserves further study.

A double-blind, multicenter study compared the safety and efficacy of oral betaxolol 10 to 40 mg once daily (n = 68) with propranolol 40 to 160 mg twice daily (n = 73) in the treatment of mild to moderate essential hypertension. Both agents produced significant (P less than 0.01) and comparable reductions in mean supine systolic and diastolic blood pressures (7/11 mm Hg on betaxolol and 9/10 mm Hg on propranolol). Both betaxolol and propranolol significantly (P less than 0.01) reduced mean supine heart rate by 9 beats per minute. Patients achieved a more significant (P less than 0.01) reduction in blood pressure earlier (weeks 2 and 4 of the titration period) with betaxolol. By the end of treatment there was no significant difference in response between treatment groups. A higher incidence of central nervous system side effects (insomnia, bizarre dreams, depression, hallucinations, dizziness), however, was seen with propranolol than with betaxolol. Overall, the data show that in patients with mild to moderate essential hypertension, betaxolol 10 to 40 mg administered once daily is as effective as and better tolerated than propranolol 40 to 160 mg administered twice daily.

This study aimed at quantifying the concentration and removal of antibiotic resistance genes (ARGs) in three municipal wastewater treatment plants (WWTPs) employing different advanced treatment systems [biological aerated filter, constructed wetland, and ultraviolet (UV) disinfection]. The concentrations of tetM, tetO, tetQ, tetW, sulI, sulII, intI1, and 16S rDNA genes were examined in wastewater and biosolid samples. In municipal WWTPs, ARG reductions of 1-3 orders of magnitude were observed, and no difference was found among the three municipal WWTPs with different treatment processes (p > 0.05). In advanced treatment systems, 1-3 orders of magnitude of reductions in ARGs were observed in constructed wetlands, 0.6-1.2 orders of magnitude of reductions in ARGs were observed in the biological aerated filter, but no apparent decrease by UV disinfection was observed. A significant difference was found between constructed wetlands and biological filter (p < 0.05) and between constructed wetlands and UV disinfection (p < 0.05). In the constructed wetlands, significant correlations were observed in the removal of ARGs and 16S rDNA genes (R(2) = 0.391-0.866; p < 0.05). Constructed wetlands not only have the comparable ARG removal values with WWTP (p > 0.05) but also have the advantage in ARG relative abundance removal, and it should be given priority to be an advanced treatment system for further ARG attenuation from WWTP.

OBJECTIVE: To evaluate the effect size of oral corticosteroid treatment on eosinophilic bronchitis in asthma, through systematic review and meta-analysis. METHODS: We systematically reviewed articles in the Medline, Cochrane Controlled Trials Register, EMBASE, and LILACS databases. We selected studies meeting the following criteria: comparing at least two groups or time points (prednisone vs. control, prednisone vs. another drug, or pre- vs. post-treatment with prednisone); and evaluating parameters before and after prednisone use, including values for sputum eosinophils, sputum eosinophil cationic protein (ECP), and sputum IL-5-with or without values for post-bronchodilator FEV1-with corresponding 95% CIs or with sufficient data for calculation. The independent variables were the use, dose, and duration of prednisone treatment. The outcomes evaluated were sputum eosinophils, IL-5, and ECP, as well as post-bronchodilator FEV1. RESULTS: The pooled analysis of the pre- vs. post-treatment data revealed a significant mean reduction in sputum eosinophils (↓8.18%; 95% CI: 7.69-8.67; p < 0.001), sputum IL-5 (↓83.64 pg/mL; 95% CI: 52.45-114.83; p < 0.001), and sputum ECP (↓267.60 µg/L; 95% CI: 244.57-290.63; p < 0.0001), as well as a significant mean increase in post-bronchodilator FEV1 (↑8.09%; 95% CI: 5.35-10.83; p < 0.001). CONCLUSIONS: In patients with moderate-to-severe eosinophilic bronchitis, treatment with prednisone caused a significant reduction in sputum eosinophil counts, as well as in the sputum levels of IL-5 and ECP. This reduction in the inflammatory response was accompanied by a significant increase in post-bronchodilator FEV1. PMID:25410844

To (1) establish the association of the most common reported symptoms on disability; and (2) study the effectiveness of treatment on disability in patients with Ehlers-Danlos syndrome-hypermobility type (EDS-HT)/hypermobility syndrome (HMS). An electronic search (Medical Subject Headings and free-text terms) was conducted in bibliographic databases CENTRAL/MEDLINE. Comparative, cross-sectional, longitudinal cohort studies and (randomized) controlled trials including patients with HMS/EDS-HT aged ≥17 years were considered for inclusion. A class of symptoms was included when 5 publications were available. In regards to treatment (physical, cognitive interventions), only (randomized) controlled trials were considered. Surgical and medicinal interventions were excluded. Bias was assessed according to the methodological scoring tools of the Cochrane collaboration. Z-score transformations were applied to classify the extent of disability in comparison with healthy controls and to ensure comparability between studies. Initially, the electronic search yielded 714 publications, and 21 articles remained for analysis after selection. The following symptoms were included for meta-analysis: pain (n=12), fatigue (n=6), and psychological distress (n=7). Pain (r=.64, P=.021), fatigue (r=.91, P=.011), and psychological distress (r=.86, P=.018) had a significant impact on disability. Regarding treatment, a significant pain reduction was achieved by a variety of physical and cognitive approaches. Treatment effectiveness on disability was not established. Disability can affect patients with HMS/EDS-HT significantly and is highly correlated with both physical and psychological factors. Although evidence is available that physical and psychological treatment modalities can induce significant pain reduction, the evidence regarding disability reduction is lacking.

To investigate the safety and efficacy of once-daily supervised oral administration of sustained-release dexamphetamine in people dependent on methamphetamine. Randomized, double-blind, placebo-controlled trial. Forty-nine methamphetamine-dependent drug users from Drug and Alcohol Services South Australia (DASSA) clinics. Participants were assigned randomly to receive up to 110 mg/day sustained-release dexamphetamine (n = 23) or placebo (n = 26) for a maximum of 12 weeks, with gradual reduction of the study medication over an additional 4 weeks. Medication was taken daily under pharmacist supervision. Primary outcome measures included treatment retention, measures of methamphetamine consumption (self-report and hair analysis), degree of methamphetamine dependence and severity of methamphetamine withdrawal. Hair samples were analysed for methamphetamine using liquid chromatography-mass spectrometry. Treatment retention was significantly different between groups, with those who received dexamphetamine remaining in treatment for an average of 86.3 days compared with 48.6 days for those receiving placebo (P = 0.014). There were significant reductions in self-reported methamphetamine use between baseline and follow-up within each group (P < 0.0001), with a trend to a greater reduction among the dexamphetamine group (P = 0.086). Based on hair analysis, there was a significant decrease in methamphetamine concentration for both groups (P < 0.0001). At follow-up, degree of methamphetamine dependence was significantly lower in the dexamphetamine group (P = 0.042). Dexamphetamine maintenance was not associated with serious adverse events. The results of this preliminary study have demonstrated that a maintenance pharmacotherapy programme of daily sustained-release amphetamine dispensing under pharmacist supervision is both feasible and safe. The increased retention in the dexamphetamine group, together with the general decreases in methamphetamine use, degree of dependence and withdrawal symptom severity, provide preliminary evidence that this may be an efficacious treatment option for methamphetamine dependence.

The Hemodialysis (HEMO) Study showed that high-dose hemodialysis providing a single-pool Kt/Vurea of 1.71 provided no benefit over a standard treatment providing a single-pool Kt/Vurea of 1.32. Here, we assessed whether the high-dose treatment used lowered plasma levels of small uremic solutes other than urea. Measurements made ≥3 months after randomization in 1281 patients in the HEMO Study showed a range in the effect of high-dose treatment compared with that of standard treatment: from no reduction in the level of p-cresol sulfate or asymmetric dimethylarginine to significant reductions in the levels of trimethylamine oxide (−9%; 95% confidence interval [95% CI], −2% to −15%), indoxyl sulfate (−11%; 95% CI, −6% to −15%), and methylguanidine (−22%; 95% CI, −18% to −27%). Levels of three other small solutes also decreased slightly; the level of urea decreased 9%. All-cause mortality did not significantly relate to the level of any of the solutes measured. Modeling indicated that the intermittency of treatment along with the presence of nondialytic clearance and/or increased solute production accounted for the limited reduction in solute levels with the higher Kt/Vurea. In conclusion, failure to achieve greater reductions in solute levels may explain the failure of high Kt/Vurea treatment to improve outcomes in the HEMO Study. Furthermore, levels of the nonurea solutes varied widely among patients in the HEMO Study, and achieved Kt/Vurea accounted for very little of this variation. These results further suggest that an index only on the basis of urea does not provide a sufficient measure of dialysis adequacy. PMID:27026365

To assess the effect of panretinal laser photocoagulation on ocular pulse amplitude (OPA) in normotensive eyes with proliferative diabetic retinopathy. Prospectively, we performed unilateral argon laser panretinal photocoagulation (PRP) in 30 patients with diabetes mellitus type II and previously untreated bilateral proliferative diabetic retinopathy. Before and 7 and 30 days after the treatment, OPA was measured using dynamic contour tonometer. Compared with the untreated contralateral eyes, laser photocoagulation led to a reduction of OPA. Ocular pulse amplitude did not significantly differ in photocoagulated eyes 7 days after the treatment, but there was a significant difference in OPA 30 days after the treatment. The decrease in OPA values was 15% 7 days after PRP and 40% 30 days after PRP. Ocular pulse amplitude reduction after PRP indirectly informs us about choriocapillary closure, already reported in previous studies.

Although diuretics are mainly used for the treatment of acute decompensated heart failure (ADHF), inadequate responses and complications have led to the use of extracorporeal ultrafiltration (UF) as an alternative strategy for reducing volume overloads in patients with ADHF. The aim of our study is to perform meta-analysis of the results obtained from studies on extracorporeal venous ultrafiltration and compare them with those of standard diuretic treatment for overload volume reduction in acute decompensated heart failure. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials databases were systematically searched using a pre‑specified criterion. Pooled estimates of outcomes after 48 h (weight change, serum creatinine level, and all-cause mortality) were computed using random effect models. Pooled weighted mean differences were calculated for weight loss and change in creatinine level, whereas a pooled risk ratio was used for the analysis of binary all-cause mortality outcome. A total of nine studies, involving 613 patients, met the eligibility criteria. The mean weight loss in patients who underwent UF therapy was 1.78 kg [95% Confidence Interval (CI): -2.65 to -0.91 kg; p < 0.001) more than those who received standard diuretic therapy. The post-intervention creatinine level, however, was not significantly different (mean change = -0.25 mg/dL; 95% CI: -0.56 to 0.06 mg/dL; p = 0.112). The risk of all-cause mortality persisted in patients treated with UF compared with patients treated with standard diuretics (Pooled RR = 1.00; 95% CI: 0.64-1.56; p = 0.993). Compared with standard diuretic therapy, UF treatment for overload volume reduction in individuals suffering from ADHF, resulted in significant reduction of body weight within 48 h. However, no significant decrease of serum creatinine level or reduction of all-cause mortality was observed.

Although antipsychotic medication has been the most widely used and efficacious treatment in ameliorating the symptoms of psychosis, there has been a growing realization that pharmacological treatment has limitations. A significant minority of individuals continue to show "treatment-resistant" symptoms and significant relapse risk, while others show symptom reduction without the corresponding improvement in social and role functioning. Psychotherapy, in combination with medication, can help with symptom reduction, as well as improve functioning and quality of life. In this paper, we focus on two modalities of psychotherapy which have been shown to improve symptomatology and functioning in individuals with psychosis: Cognitive Behavior Therapy for psychosis (CBTp) and Metacognitive Training (MCT). Both treatment approaches focus on increasing the individuals' understanding of the psychological mechanisms associated with delusions and hallucinations, and helping them develop strategies to improve reality testing and belief evaluation. We aim to provide an overview of both treatments, examining not only the theoretical mechanisms and efficacy of each approach, but also the common therapeutic components they share.

A titratable thermoplastic mandibular advancement device (MAD) is clearly an effective treatment option in some patients with obstructive sleep apnea (OSA). Determining which patients may be more likely to respond to treatment with thermoplastic MADs and to adhere to treatment would be of obvious clinical relevance. This was an experimental descriptive study (N = 60). Patients with OSA were instructed to wear a titratable thermoplastic MAD for 3 months. Treatment success was defined as a ≥50% reduction from baseline in the apnea-hypopnea index (AHI) or AHI <10 when wearing MAD. Adherence was defined as MAD use ≥5 nights/week. Treatment was successful in 66.7% of patients and 60.0% were adherent. All polysomnographic parameters and visual analogue scale scores (sleep quality, snoring, waking refreshed) were significantly improved after treatment. The patients in whom treatment failed had significantly higher neck circumferences (39.3 cm vs. 37.5 cm, p = 0.014), higher baseline AHI values (26.6 vs. 18.0, p = 0.016), and smaller AHI reduction (-31.8 vs -53.1, p < 0.001) than those in the group in whom treatment succeeded. There were no significant differences in polysomnographic, cephalometric, or visual analogue scale measures between patients for whom treatment was and was not successful, regardless of baseline values or the change rates after the MAD was placed. Titratable thermoplastic MADs can improve indicators of sleep quality, even in patients in whom treatment is considered to have failed.

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

Positron emission tomography (PET) studies of methamphetamine (METH) abusers suggest that psychotic symptoms of METH abusers may be attributable to the reduction of dopamine transporters (DAT) in the human brain. However, there are currently no particular pharmacological treatments for the wide range of symptoms associated with METH abuse. Using a PET study in conscious monkeys, we investigated whether the second generation antibiotic minocycline could protect against the reduction of DAT in monkeys treated with METH (2 mg/kg x 3, 3-hour intervals). Pretreatment and subsequent administration of minocycline significantly attenuated the reduction of DAT in the striatum of monkeys treated with METH. Furthermore, posttreatment and subsequent administration of minocycline also significantly attenuated the reduction of DAT. In contrast, repeated administration of minocycline alone did not alter the density of DAT in the striatum of monkeys treated with METH. Our findings suggest that minocycline protects against METH-induced neurotoxicity in the monkey brain. Therefore, minocycline is likely to be a promising therapeutic agent for the treatment of several symptoms associated with METH use in humans.

This case study enhances the understanding of open automated demand response opportunities in municipal wastewater treatment facilities. The report summarizes the findings of a 100 day submetering project at the San Luis Rey Wastewater Treatment Plant, a municipal wastewater treatment facility in Oceanside, California. The report reveals that key energy-intensive equipment such as pumps and centrifuges can be targeted for large load reductions. Demand response tests on the effluent pumps resulted a 300 kW load reduction and tests on centrifuges resulted in a 40 kW load reduction. Although tests on the facility?s blowers resulted in peak period load reductions ofmore » 78 kW sharp, short-lived increases in the turbidity of the wastewater effluent were experienced within 24 hours of the test. The results of these tests, which were conducted on blowers without variable speed drive capability, would not be acceptable and warrant further study. This study finds that wastewater treatment facilities have significant open automated demand response potential. However, limiting factors to implementing demand response are the reaction of effluent turbidity to reduced aeration load, along with the cogeneration capabilities of municipal facilities, including existing power purchase agreements and utility receptiveness to purchasing electricity from cogeneration facilities.« less

A systematic review of cognitive and/or behavioural therapies for methamphetamine dependence

Introduction and aims The use of methamphetamine is widespread and poses significant challenges for treatment providers. Much of the treatment knowledge about this group has been extrapolated from studies of treatment for cocaine dependence. Medications have been shown to be of limited effectiveness for methamphetamine users, making psychological interventions the treatment of choice. Design and methods This paper describes a systematic review of cognitive-behavioural and behavioural interventions for methamphetamine users. A systematic search of published literature was undertaken focusing only on randomised trials. Results There were a relatively small number of intervention studies that compared cognitive-behavioural or behavioural interventions using randomised trial methodology. Most commonly, studies examined cognitive behaviour therapy (CBT) and/or contingency management (CM). Treatment with CBT appears to be associated with reductions in methamphetamine use and other positive changes ,even over very short periods of treatment (2 and 4 sessions). CM studies found a significant reduction of methamphetamine during application of the procedure, but it is not clear if these gains are sustained at post-treatment follow-up. Discussion and conclusion Further research into cognitive behavioural and behavioural treatments for methamphetamine users is required, with a focus on improving longevity of the effect of intervention.

Twenty-one OCD sufferers with washing/contamination concerns took part in a controlled treatment trial at the Anxiety Disorders Clinic, University of Sydney. Eleven of the subjects received danger ideation reduction therapy (DIRT) over eight, 1 h weekly group sessions conducted by the second author. Ten subjects were placed on a wait list and did not receive DIRT or any other treatment. DIRT procedures were solely directed at decreasing danger-related expectancies concerning contamination and did not include exposure, response prevention or behavioral experiments. Components of DIRT include attentional focusing, filmed interviews, corrective information, cognitive restructuring, expert testimony, microbiological experiments and a probability of catastrophe assessment task. All subjects were assessed at pre-treatment, post-treatment and three-month follow-up using the Maudsley Obsessional-Compulsive Inventory, Leyton Obsessionality Inventory, Beck Depression Inventory and a Self Rating of Severity Scale. Changes from pre-treatment to after treatment (post-treatment and follow-up scores averaged) were significantly greater in the DIRT condition than in the control condition for all measures. No significant differences were obtained between groups on post-treatment to follow-up change on any measure. The implications of these findings for theoretical models of OCD and its management are discussed.

Niacin reduces plasma triglycerides, but it may increase free fatty acids and insulin resistance during long-term treatment. We examined the effect of extended-release niacin on liver fat content in Chinese patients with dyslipidemia and whether the common diacylglycerol acyltransferase-2 (DGAT2) polymorphisms influenced this effect. The 39 patients (baseline liver fat content: 12.8 ± 7.6%, triglycerides: 3.30 ± 1.67 mmol/l) were treated with niacin, gradually increasing the dose to 2 g/day for a total of 23 weeks. The liver fat content and visceral/subcutaneous fat was measured before and after treatment. Subjects were genotyped for the DGAT2 rs3060 and rs101899116 polymorphisms. There were significant (P < 0.001) reductions in plasma triglycerides (−34.9 ± 37.6%), liver fat content (−47.2 ± 32.8%), and visceral fat (−6.3 ± 15.8%, P < 0.05) after niacin treatment. Mean body weight decreased by 1.46 ± 2.7% (1.17 ± 2.44 kg, P < 0.001) during the study, but liver fat changes remained significant after adjustment for age, gender, and body weight changes [mean absolute change (95% CI): −6.1% (−8.0, −4.3), P < 0.001]. The DGAT2 variant alleles were associated with a smaller reduction in liver fat content in response to niacin after adjustment for other covariates (P < 0.01). These findings suggest that niacin treatment may reduce liver fat content in Chinese patients with dyslipidemia and that the mechanism may involve inhibition of DGAT2. However, the findings might have been confounded by the small but significant reductions in body weight during the study. Future large randomized controlled trials are needed to verify these findings. PMID:22315393

Acne vulgaris is common in young adolescents. Retinoids are widely used but may be associated with poor tolerability. This post hoc analysis of 483 participants aged 10 to 14 years with mild to moderate acne compared efficacy and tolerability of once-daily treatment with micronized tretinoin gel 0.05%, tretinoin gel microsphere 0.1%, and vehicle over 12 weeks. In study 1, inflammatory and noninflammatory lesion reduction and treatment success was comparable between tretinoin gel 0.05% and tretinoin gel microsphere 0.1%. Inflammatory (46.3%) and noninflammatory (45.7%) lesion reductions with tretinoin gel 0.05% were significantly greater than vehicle (37.1% and 27.9%, respectively) (both P<.001). In study 2, inflammatory and noninflammatory lesion reductions and treatment success with tretinoin gel 0.05% (30.6%, 39.1%, and 19%, respectively) were significantly greater than vehicle (10.9%, 16.9% [both P<.001], and 4% [P=.008], respectively). Tretinoin gel 0.05% was significantly better tolerated than tretinoin gel microsphere 0.1% (P<.001); the majority of adverse events (AEs) were mild, occurring in the first 2 weeks. Fourteen percent of participants reported dry skin, 8% skin burning sensation, 5% erythema, and 5% dermatitis exfoliative with tretinoin gel 0.05% compared with 32%, 11%, 23%, and 23%, respectively, with tretinoin gel microsphere 0.1% (all P<.001, except skin burning sensation). In this secondary analysis of acne in young adolescents aged 10 to 14 years, micronized tretinoin gel 0.05% provided a comparable lesion reduction and treatment success versus tretinoin gel microsphere 0.1%, with a better cutaneous tolerability profile.

Bacteria permeabilization and disruption caused by sludge reduction technologies evaluated by flow cytometry.

Technologies proposed in the last decades for the reduction of the sludge production in wastewater treatment plants and based on the mechanism of cell lysis-cryptic growth (physical, mechanical, thermal, chemical, oxidative treatments) have been widely investigated at lab-, pilot- and, in some cases, at full-scale but the effects on cellular lysis have not always been demonstrated in depth. The research presented in this paper aims to investigate how these sludge reduction technologies affect the integrity and permeabilization of bacterial cells in sludge using flow cytometry (FCM), which permits the rapid and statistically accurate quantification of intact, permeabilised or disrupted bacteria in the sludge using a double fluorescent DNA-staining instead of using conventional methods like plate counts and microscope. Physical/mechanical treatments (ultrasonication and high pressure homogenisation) caused moderate effects on cell integrity and caused significant cell disruption only at high specific energy levels. Conversely, thermal treatment caused significant damage of bacterial membranes even at moderate temperatures (45-55 °C). Ozonation significantly affected cell integrity, even at low ozone dosages, below 10 mgO(3)/gTSS, causing an increase of permeabilised and disrupted cells. At higher ozone dosages the compounds solubilised after cell lysis act as scavengers in the competition between soluble compounds and (particulate) bacterial cells. An original aspect of this paper, not yet reported in the literature, is the comparison of the effects of these sludge reduction technologies on bacterial cell integrity and permeabilization by converting pressure, temperature and ozone dosage to an equivalent value of specific energy. Among these technologies, comparison of the applied specific energy demonstrates that achieving the complete disruption of bacterial cells is not always economically advantageous because excessive energy levels may be required.

Open reduction and internal fixation of pelvic fractures could restore the stability of the pelvic ring, but there were several problems. Minimally invasive closed reduction cannulated screw treatment of pelvic fractures has lots advantages. However, how to insert the cannulated screw safely and effectively to achieve a reliable fixation were still hard for orthopedist. Our aim was to explore the significance of 3D printing technology as a new method for minimally invasive cannulated screw treatment of unstable pelvic fracture. One hundred thirty-seven patients with unstable pelvic fractures from 2014 to 2016 were retrospectively analyzed. Based on the usage of 3D printing technology for preoperative simulation surgery, they were assigned to 3D printing group (n = 65) and control group (n = 72), respectively. These two groups were assessed in terms of operative time, intraoperative fluoroscopy, postoperative reduction effect, fracture healing time, and follow-up function. The effect of 3D printing technology was evaluated through minimally invasive cannulated screw treatment. There was no significant difference in these two groups with respect to general conditions, such as age, gender, fracture type, time from injury to operation, injury cause, and combined injury. Length of surgery and average number of fluoroscopies were statistically different for 3D printing group and the control group (p < 0.01), i.e., 58.6 vs. 72.3 min and 29.3 vs. 37 min, respectively. Using the Matta radiological scoring systems, the reduction was scored excellent in 21/65 cases (32.3%) and good in 30/65 cases (46.2%) for the 3D printing group, versus 22/72 cases (30.6%) scored as excellent and 36/72 cases (50%) as good for the control group. On the other hand, using the Majeed functional scoring criteria, there were 27/65 (41.5%) excellent and 26/65 (40%) good cases for the 3D printing group in comparison to 30/72 (41.7%) and 28/72 (38.9%) cases for the control group, respectively. This suggests no significant difference between these two groups about the function outcomes. Full reduction and proper fixation of the pelvic ring and reconstruction of anatomical morphology are of great significance to patients' early functional exercise and for the reduction of long-term complications. This retrospective study has demonstrated the 3D printing technology as a potential approach for improving the diagnosis and treatment of pelvic fractures. The study was retrospectively registered at the Chinese Clinical Trial Registry, number: ChiCTR-TRC-17012798, trial registration date: 26 Sept. 2017.

Mucositis is a significant complication of intensive chemotherapy or hematopoietic cell transplantation (HCT), with few treatment options. Ketamine mouthwashes have been used for pain relief, but supporting evidence is limited. The primary objective of this study was to assess the reduction in pain intensity of stomatodynia and odynophagia compared to baseline assessment. This open-label, prospective, phase II interventional study (NCT01566448) was conducted from February 2012 through July 2015. Patients with grade 3 or 4 oral mucositis according to the World Health Organization (WHO) scale as a result of chemotherapy were treated with ketamine mouthwash 20 mg/5 mL four times daily and every 4 h as needed. Thirty patients were enrolled and a total of 136 assessments were conducted. A statistically significant reduction in pain scores of 2 and 3 points was achieved after 1 h and 3 days, respectively (p < 0.0001, p = 0.0003). Pain scores were significantly improved while swallowing, reduced 1 and 4 points at 1-h and 3-day assessment, respectively (p = 0.0006, p = 0.0001). No patients developed adverse effects related to ketamine administration. Ketamine mouthwashes resulted in clinically meaningful and statistically significant reduction in pain scores, have an acceptable safety profile, and can be a useful adjunctive treatment in the multi-modal management of severe mucositis.

The aim was to investigate the nephroprotective effect of combination of aliskiren (ASK), a direct renin inhibitor and pentoxifylline (PTX), inhibitor of tumor necrotic factor-alpha (TNF-alpha), in rat remnant kidney model of chronic kidney disease (CKD). Nephrectomized (NPX) rats were treated with ASK (10 mg/kg, p.o.), PTX (100 mg/kg, p.o.), and combination of PTX + ASK once daily for 28 days. We have performed analysis of various renal injury parameters after 4 weeks of treatment. Treatment with PTX, ASK and combination showed significant improvement in urea, creatinine and total protein in plasma when compared with vehicle treated group in NPX rats. ASK and combination of PTX + ASK elicited significant reduction in blood pressure but PTX alone did not produce blood pressure reduction. ASK treatment showed significant elevation in TNF-alpha, whereas PTX and ASK + PTX showed significant reduction in TNF-alpha in plasma. Histopathologically, the extent of the kidney injury was similar in NPX + vehicle and NPX + ASK-treated rats. PTX and ASK + PTX-treated group showed lesser extent of kidney injury. There was good correlation of mRNA expression levels of kidney injury molecule-1 and bradykinin B1 receptor data with histopathological findings in kidney samples and elevated TNF-alpha levels in plasma. We conclude that combination of PTX + ASK may be better therapeutic intervention for nephroprotection in CKD patients.

Cryolipolysis is a nonsurgical technique for localized fat reduction. With the increased risk of complications from more invasive methods such as liposuction, cryolipolysis presents a promising method for nonsurgical body contouring. This study presents a systematic review of the available clinical data, with an emphasis on the efficacy, methods, safety, and complications of cryolipolysis. To identify clinical studies that assessed outcomes of cryolipolysis, a systematic review of the MEDLINE and Cochrane databases was performed with the search algorithm cryolipolysis OR cool sculpting OR fat freezing OR lipocryolysis. The primary literature search returned 319 articles. After inclusion criteria were applied and additional articles were idenfied via manual review of article references, 19 studies were selected for review. Average reduction in caliper measurement ranged from 14.67 percent to 28.5 percent. Average reduction by ultrasound ranged from 10.3 percent to 25.5 percent. No significant impact on lipid levels or liver function tests after cryolipolysis treatments was noted in any study. Only mild, short-term side effects, such as erythema, swelling, and pain, were noted. Paradoxical adipose hyperplasia was described in one patient. Cryolipolysis is a promising procedure for nonsurgical fat reduction and body contouring and presents a compelling alternative to liposuction and other, more invasive methods. This procedure appears to be safe in the short term, with a limited side effect profile, and results in significant fat reduction when used for localized adiposities. It remains unclear whether posttreatment manual massage and multiple treatments in the same anatomic area enhance the efficacy of cryolipolysis.

Conversion Disorder, Functional Neurological Symptom Disorder, and Chronic Pain: Comorbidity, Assessment, and Treatment.

This paper examines the overlap of conversion disorder with chronic pain conditions, describes ways to assess for conversion disorder, and provides an overview of evidence-based treatments for conversion disorder and chronic pain, with a focus on conversion symptoms. Conversion disorder is a significant problem that warrants further study, given that there are not many well-established guidelines. Accurate and timely assessment should help move treatment in a more fruitful direction and avoid unnecessary medical interventions. Advances in neuroimaging may also help further our understanding of conversion disorder. Creating a supportive environment and a collaborative treatment relationship and improving understanding of conversion symptoms appear to help individuals diagnosed with conversion disorder engage in appropriate treatments. Novel uses of earlier treatments, such as hypnosis and psychodynamic approaches, could potentially be beneficial and require a more vigorous and systematic study. There are treatments that produce significant improvements in functioning and reduction of physical symptoms from conversion disorder even for very severe cases. Hypnotherapy, cognitive behavioral therapy, and inpatient multidisciplinary treatment with intensive physiotherapy for severe cases have the most evidence to support reduction of symptoms. Components of treatment for conversion disorder overlap with treatments for chronic pain and can be used together to produce therapeutic effects for both conditions. Treatment needs to be tailored for each individual's specific symptoms.

Waterborne outbreaks of gastrointestinal diseases are of great concern to drinking water producers and can give rise to substantial costs to the society. The World Health Organisation promotes an approach where the emphasis is on mitigating risks close to the contamination source. In order to handle microbial risks efficiently, there is a need for systematic risk management. In this paper we present a framework for microbial risk management of drinking water systems. The framework incorporates cost-benefit analysis as a decision support method. The hydrological Soil and Water Assessment Tool (SWAT) model, which was set up for the Stäket catchment area in Sweden, was used to simulate the effects of four different mitigation measures on microbial concentrations. The modelling results showed that the two mitigation measures that resulted in a significant (p < 0.05) reduction of Cryptosporidium spp. and Escherichia coli concentrations were a vegetative filter strip linked to cropland and improved treatment (by one Log10 unit) at the wastewater treatment plants. The mitigation measure with a vegetative filter strip linked to grazing areas resulted in a significant reduction of Cryptosporidium spp., but not of E. coli concentrations. The mitigation measure with enhancing the removal efficiency of all on-site wastewater treatment systems (total removal of 2 Log10 units) did not achieve any significant reduction of E. coli or Cryptosporidium spp. concentrations. The SWAT model was useful when characterising the effect of different mitigation measures on microbial concentrations. Hydrological modelling implemented within an appropriate risk management framework is a key decision support element as it identifies the most efficient alternative for microbial risk reduction.

The efficacy and safety of clindamycin phosphate 1.2%/tretinoin 0.025% (Clin-RA) were evaluated in three 12-week randomised studies. To perform a pooled analysis of data from these studies to evaluate Clin-RA's efficacy and safety in a larger overall population, in subgroups of adolescents and according to acne severity. 4550 patients were randomised to Clin-RA, clindamycin, tretinoin and vehicle. Evaluations included percentage change in lesions, treatment success rate, proportions of patients with ≥50% or ≥80% continuous reduction in lesions, adverse events and cutaneous tolerability. In the overall population, the percentage reduction in inflammatory, non-inflammatory and total lesions and the treatment success rate were significantly greater with Clin-RA compared with clindamycin, tretinoin and vehicle alone (all p<0.01). The percentage reduction in all types of lesions was also significantly greater with Clin-RA in the adolescent subgroup (2915 patients, p<0.002) and in patients with mild/moderate acne (3662 patients, p<0.02) versus comparators. In patients with severe acne (n = 880), the percentage reduction in all lesion types was significantly greater with Clin-RA versus vehicle (p<0.0001). A greater proportion of Clin-RA treated patients had a ≥50% or ≥80% continuous reduction in all types of lesions at week 12 compared with clindamycin, tretinoin and vehicle. Adverse event frequencies in the active and vehicle groups were similar. Baseline-adjusted mean tolerability scores over time were <1 (mild) and similar in all groups. Clin-RA is safe, has superior efficacy to its component monotherapies and should be considered as one of the first-line therapies for mild-to-moderate facial acne.

Data on whether periodontal therapy affects serum CRP levels are inconclusive. The aim of this study was to determine if nonsurgical periodontal therapy has any effect on CRP and serum lipid levels in patients with advanced periodontitis. Thirty-six systemically healthy patients, ≥ 40 years of age and with advanced periodontitis, were recruited for the study. Patients were randomized consecutively to one of two groups: the treatment group (n = 18) or the control group (n = 18). Treated subjects received nonsurgical periodontal therapy, which included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers [C-reactive protein (CRP) and the lipid profile] were measured at baseline and 3 mo after periodontal therapy. Nonsurgical periodontal therapy in the treatment group resulted in a significant reduction in the serum CRP level. The average CRP level decreased from 2.3 mg/dL at baseline to 1.8 mg/dL (p < 0.005) after 3 mo of periodontal therapy. The average reduction (95% confidence interval) in CRP was 0.498 (95% confidence interval = 0.265-0.731). In the treatment group, the reduction in CRP was significantly, linearly and directly correlated with the reduction in the plaque index, the gingival index and the percentage of sites with pocket depth ≥ 7 mm (Pearson correlation coefficient = 0.746, 0.425 and 0.621, respectively). Nonsurgical periodontal therapy had no effect on the lipid parameters. This study demonstrated that nonsurgical periodontal therapy results in a significant reduction in the serum CRP level. The effect of this outcome on systemic disease is still unknown. © 2011 John Wiley & Sons A/S.

Zebra mussels (Dreissena polymorpha) limit food for larval fish (Pimephales promelas) in turbulent systems: A bioenergetics analysis

We conducted a factorial experiment, in outdoor mesocosms, on the effects of zebra mussels and water column mixing (i.e., turbulence) on the diet, growth, and survival of larval fathead minnows (Pimephales promelas). Significant (P < 0.05) larval mortality occurred by the end of the experiment with the highest mortality (90%) occurring in the presence of both turbulence and zebra mussels, whereas mortality was 37% in treatment with turbulence and 17% and 18% in the zebra mussels treatment, and the control, respectively. The size of individual fish was significantly different among treatments at the end of the experiment and was inversely related to survival. Levels of trophic resources (i.e., phyto and zooplankton) varied among treatments and were treatment specific. Turbulent mixing facilitated removal of phytoplankton by zebra mussels by making the entire water column of the tanks available to these benthic filter feeders. Early in the experiment (Day = 0 to 14) the physical process of turbulent mixing likely caused a reduction in standing stocks of zooplankton. The interactive effect of turbulence and mussels reduced copepod and rotifer stocks, through physical processes and through filtration by zebra mussels, relative to the turbulence treatment. The reductions in the number of total zooplankton in the turbulent mixing mesocosms and the further reduction of rotifer and copepod in the turbulence and mussels treatment coincided with a period of increased reliance of larval fathead minnows on these prey. Estimates of consumption from bioenergetics modeling and measured prey standing stocks indicated caloric resources of suitable prey in turbulence treatments during the early weeks of the experiment were insufficient to prevent starvation. Early mortality in the turbulence and mussels treatment likely released surviving fish from intense intraspecific competition and resulted in higher individual growth rates. A combination of high abundance of zebra mussels in an environment with a well-mixed water column can have significant effects on larval fish survival and growth.

Effectiveness of interventions to screen and manage infections during pregnancy on reducing stillbirths: a review

PubMed Central

2011-01-01

Background Infection is a well acknowledged cause of stillbirths and may account for about half of all perinatal deaths today, especially in developing countries. This review presents the impact of interventions targeting various important infections during pregnancy on stillbirth or perinatal mortality. Methods We undertook a systematic review including all relevant literature on interventions dealing with infections during pregnancy for assessment of effects on stillbirths or perinatal mortality. The quality of the evidence was assessed using the adapted Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach by Child Health Epidemiology Reference Group (CHERG). For the outcome of interest, namely stillbirth, we applied the rules developed by CHERG to recommend a final estimate for reduction in stillbirth for input to the Lives Saved Tool (LiST) model. Results A total of 25 studies were included in the review. A random-effects meta-analysis of observational studies of detection and treatment of syphilis during pregnancy showed a significant 80% reduction in stillbirths [Relative risk (RR) = 0.20; 95% confidence interval (CI): 0.12 - 0.34) that is recommended for inclusion in the LiST model. Our meta-analysis showed the malaria prevention interventions i.e. intermittent preventive treatment (IPTp) and insecticide-treated mosquito nets (ITNs) can reduce stillbirths by 22%, however results were not statistically significant (RR = 0.78; 95% CI: 0.59 – 1.03). For human immunodeficiency virus infection, a pooled analysis of 6 radomized controlled trials (RCTs) failed to show a statistically significant reduction in stillbirth with the use of antiretroviral in pregnancy compared to placebo (RR = 0.93; 95% CI: 0.45 – 1.92). Similarly, pooled analysis combining four studies for the treatment of bacterial vaginosis (3 for oral and 1 for vaginal antibiotic) failed to yield a significant impact on perinatal mortality (OR = 0.88; 95% CI: 0.50 – 1.55). Conclusions The clearest evidence of impact in stillbirth reduction was found for adequate prevention and treatment of syphilis infection and possibly malaria. At present, large gaps exist in the growing list of stillbirth risk factors, especially those that are infection related. Potential causes of stillbirths including HIV and TORCH infections need to be investigated further to help establish the role of prevention/treatment and its subsequent impact on stillbirth reduction.

To analyze the changes in pain severity and associated costs resulting from resource utilization and reduced productivity in patients with gabapentin-refractory peripheral neuropathic pain who switched to pregabalin therapy in primary care settings in Spain. This is a post hoc analysis of a 12-week, multicentre, noninterventional cost-of-illness study. Patients were included in the study if they were over 18 years of age and had a diagnosis of chronic, treatment-refractory peripheral neuropathic pain. The analysis included all pregabalin-naïve patients who had previously shown an inadequate response to gabapentin and switched to pregabalin. Severity of pain before and after treatment with pregabalin, alone or as an add-on therapy, was assessed using the Short-Form McGill Pain Questionnaire (SF-MPQ) and its related visual analogue scale (VA). Healthcare resource utilization, productivity (including lost-workday equivalents [LWDE]), and related costs were assessed at baseline and after pregabalin treatment. A total of 174 patients switched to pregabalin had significant and clinically relevant reductions in pain severity (mean [SD] change on SF-MPQ VA scale, -31.9 [22.1]; P < 0.05 vs. baseline; effect size, 1.87). Reduction in pain was similar with both pregabalin monotherapy and add-on therapy. Significant reductions in healthcare resource utilization (concomitant drug use [in pregabalin add-on group], ancillary tests, and unscheduled medical visits) were observed at the end of trial. Additionally, there were substantial improvements in productivity, including a reduction in the number of LWDE following pregabalin treatment (-18.9 [26.0]; P < 0.0001). These changes correlated with substantial reductions in both direct (-652.9 ± 1622.4 €; P < 0.0001) and indirect healthcare costs (-851.6 [1259.6] €; P < 0.0001). The cost of care in patients with gabapentin-refractory peripheral neuropathic pain appeared to be significantly reduced after switching to pregabalin treatment, alone or in combination with other analgesic drugs, in a real-life setting. © 2011 The Authors.

This pilot study evaluated a 12-week group treatment program for preschool children with interpersonal sexual behavior problems (SBP; N = 85; 53 completed at least 8 sessions). Many children presented with co-occurring trauma symptoms and disruptive behaviors. In intent-to-treat analysis, a significant linear reduction in SBP due to number of treatment sessions attended was found, an effect that was independent of linear reductions affiliated with elapsed time. Under the assumption that treatment can have an incremental impact, more than one third of the variance was accounted for by treatment effects, with female and older children most favorably impacted. Caregivers reported increase in knowledge, satisfaction, and usefulness of treatment. In addition to replication, future research is needed to examine (a) effects of environment change and time on SBP, (b) stability of treatment effects, and (c) best practices to integrate evidence-based treatments for comorbid conditions.

Purpose This study sought to test whether the relationship between experiential acceptance (EA) and treatment outcome among eating disorder (ED) patients was mediated by motivation. Methods Upon admission to a residential ED treatment facility, female patients completed measures of EA, motivation, and baseline ED symptom severity (covariate); symptom severity was reassessed at discharge. Results Higher levels of baseline EA predicted significantly greater symptom reduction during treatment. Moreover, results from bootstrapped mediation analyses indicated that the relationship between EA and treatment outcome was partially mediated by motivation: increased EA was associated with greater motivation to give up ED behaviors at the beginning of treatment, and this led to greater symptom reduction from admission to discharge. Conclusions Motivation appears to be one mechanism by which EA facilitates improved treatment outcomes in EDs. Further development of interventions that promote EA as a means for improving motivation and subsequent ED treatment response may be warranted. PMID:26511501

If presented with serious mental illness (SMI), individuals' low help-seeking behaviors and poor adherence to treatment are associated with negative stereotypes and attitudes of healthcare providers. In this study, we examined the effects of a brief psychoeducational program on reducing stigma in pre-clinical medical students. One hundred and two pre-clinical medical students (20-23 years old) were randomly assigned to face-to-face contact + educational lecture (n = 51) condition or video-based contact + educational lecture (n = 51) condition. Measures of pre-clinical medical students' mental illness-related stigma using the Opening Minds Stigma Scale for Health Care Providers (OMS-HC) were administered at pre-, post-treatment, and 1-month follow-up. A 2 (condition: face-to-face contact + educational lecture, video-based contact + educational lecture) by 3 (time: pre-treatment, post-treatment, and 1-month follow-up) mixed model MANOVA was conducted on the Attitudes, Disclosure and Help-Seeking, and Social Distance OMS-HC subscales. Participants' scores on all subscales changed significantly across time, regardless of conditions. To determine how participants' scores changed significantly over time on each subscale, Bonferroni follow-up comparisons were performed to access pairwise differences for the main effect of time. Specifically, pairwise comparisons produced a significant reduction in Social Distance subscale between pre-treatment and post-treatment and between pre-treatment and 1-month follow-up, and a significant increase between post-treatment and 1-month follow-up, regardless of conditions. With respect to the Attitudes and Disclosure and Help-Seeking subscales, pairwise comparisons produced a significant reduction in scores between pre-treatment and post-treatment and a significant increase between post-treatment and 1-month follow-up. Our findings provide additional evidence that educational lecture on mental illness, coupled with either face-to-face contact or video-based contact, is predictive of positive outcomes in anti-stigma programs targeting future healthcare providers.

Streptozotocin (STZ), a glucose analog, induces diabetes in experimental animals by inducing preferential cytotoxicity in pancreatic beta cells. We investigated whether STZ reduced the production of intracellular insulin through autophagy in insulinoma INS-1E cells. Typically, 2 mM STZ treatment for 24 h significantly decreased cell survival. STZ treatment led to significant decrease in phospho-AMP-activated protein kinase (p-AMPK) level; reduction in levels of phospho-protein kinase R-like endoplasmic reticulum kinase (PERK) and inositol-requiring enzyme 1α (IRE1α); significant reduction in levels of p85α, p110, phospho-serine and threonine kinase/protein kinase B (p-Akt/PKB) (Ser473), phospho-extracellular-regulated kinase (p-ERK), and phospho-mammalian target of rapamycin (p-mTOR); increase in levels of Cu/Zn-superoxide dismutase (SOD), Mn-SOD, and catalase; decrease in B-cell lymphoma 2 (Bcl-2) expression; increase in Bcl-2-associated X protein (Bax) expression; increase in levels of microtubule-associated protein 1 light chain 3 (LC3) and Beclin 1; and reduction in production of intracellular insulin. These results suggest that insulin synthesis during STZ treatment involves autophagy in INS-1E cells and, subsequently, results in a decrease in intracellular production of insulin.

2013-07-01

In nuclear power plants (NPP) ion exchange (IX) resins are used in several systems for water treatment. Spent resins can contain a significant amount of contaminates which makes treatment for disposal of spent resins mandatory. Several treatment processes are available such as direct immobilization with technologies like cementation, bitumisation, polymer solidification or usage of a high integrity container (HIC). These technologies usually come with a significant increase in final waste volume. The Hot Resin Supercompaction (HRSC) is a thermal treatment process which reduces the resin waste volume significantly. For a mixture of powdered and bead resins the HRSC process hasmore » demonstrated a volume reduction of up to 75 % [1]. For bead resins only the HRSC process is challenging because the bead resins compaction properties are unfavorable. The bead resin material does not form a solid block after compaction and shows a high spring back effect. The volume reduction of bead resins is not as good as for the mixture described in [1]. The compaction properties of bead resin waste can be significantly improved by grinding the beads to powder. The grinding also eliminates the need for a powder additive.Westinghouse has developed a modular grinding process to grind the bead resin to powder. The developed process requires no circulation of resins and enables a selective adjustment of particle size and distribution to achieve optimal results in the HRSC or in any other following process. A special grinding tool setup is use to minimize maintenance and radiation exposure to personnel. (authors)« less

Success of anger management treatment with individuals who have intellectual disabilities convicted of assault-related offenses has not been verified. We employed a single case design with repeated measures with 6 such men. Recidivism is reported at least 4.5 years and up to 10 years. Modified anger management training incorporating cognitive restructuring and arousal reduction was employed. Participants showed no uniform reductions in emotional or behavioral systems of anger and aggression. Although several retained significant anger feelings, there were reductions in the extent to which they would act in an aggressive fashion. Five have not re-offended; 1 re-offended within 6 months but not in the subsequent 4 years. Anger management treatment seems effective for men with intellectual disabilities in the community who have committed socially and legally unacceptable acts.

People with venous thromboembolism are generally treated for five days with intravenous unfractionated heparin or subcutaneous low-molecular-weight heparin followed by three months of vitamin K antagonists treatment. Treatment with vitamin K antagonists requires regular laboratory measurements and some patients have contraindications for treatment. To evaluate the efficacy and safety of long-term treatment of venous thromboembolism with low-molecular-weight heparins compared to vitamin K antagonists. Searches of MEDLINE, EMBASE and ISI Web of Science, the Specialised Trials Register of the Cochrane Peripheral Vascular Disease Group and the Cochrane Controlled Trials Register were made and relevant journals were hand-searched. Additional trials were sought through communication with colleagues and pharmaceutical companies. Two reviewers evaluated studies independently for methodological quality. Two reviewers extracted data independently. Primary analysis concerned all trial participants during the period of randomized treatment. Separate analyses were performed for category I and category II studies; i.e. studies using similar treatments initially in both study arms, and those that did not; and the different periods of follow-up. All seven studies fulfilling our criteria combined, a statistically non-significant reduction in the risk of recurrent venous thromboembolism favoring low-molecular-weight heparin treatment (OR 0.70; 95% CI [0.42, 1.16]) was found. Analysis of pooled data for category I studies showed a non-significant reduction in the risk of recurrent venous thromboembolism favoring low-molecular-weight heparin treatment (OR 0.75; 95% CI [0.40, 1.39]). Omitting a potentially-confounded study, a statistically non-significant reduction in the risk of recurrent venous thromboembolism favoring vitamin K antagonist treatment remained (OR 1.95; 95% CI [0.74, 5.19]). All studies combined, the difference in bleeding significantly favored treatment with low-molecular-weight heparin (OR 0.38; 95% CI [0.15, 0.94]), however, considering only category I studies a non-significant trend favoring low-molecular-weight heparin remained (OR 0.80; 95% CI [0.21, 3.00]). No difference was observed in mortality (OR 1.13; 95% CI [0.47, 2.69]). Low-molecular-weight heparins are possibly as effective as vitamin K antagonists in preventing symptomatic venous thromboembolism after an episode of symptomatic deep venous thrombosis, but are much more expensive. Treatment with low-molecular-weight heparin is significantly safer than treatment with vitamin K antagonists and is possibly a safe alternative in some patients; especially those in geographically inaccessible places, reluctant to visit the thrombosis service regularly, or with contraindications to vitamin K antagonists. However, treatment with vitamin K antagonists remains the treatment of choice for the majority of patients.

The purpose of this randomized, single blinded clinical trial was to evaluate cytologically and clinically the efficacy of oral cephalexin alone and its combination with terbinafine or ketoconazole for the treatment of Malassezia dermatitis in dogs. Twenty-two client-owned dogs with Malassezia dermatitis completed the 3-week study. All received cephalexin (generic, 250 mg or 500 mg) at 22-30 mg kg(-1) twice daily. Eight dogs received terbinafine at 30 mg kg(-1) once daily and seven dogs received ketoconazole (generic, 200 mg) at 5-10 mg kg(-1) twice daily. The remaining seven dogs received cephalexin alone. At week 0 (visit 1) and week 3 (visit 2), mean yeast counts were determined from three affected areas using tape-strip cytology, a clinical index score (CIS) was assigned to the affected areas, and owners evaluated pruritus using a visual analogue scale. All groups showed reduction in mean yeast counts, CIS and pruritus. There was an 86.8%, 80.2% and 28.8% reduction in mean yeast counts from visit 1 to visit 2 for the terbinafine, ketoconazole and cephalexin-only groups, respectively. However, within treatment group comparisons a significant reduction in mean yeast count was only evident for the terbinafine (P < 0.002) and ketoconazole (P < 0.01) groups. Pruritus reduction was only significant for the terbinafine group. These preliminary results suggest that terbinafine should be further assessed for the treatment of canine Malassezia dermatitis.

Pressure drop associated with coarctation of the aorta (CoA) can be successfully treated surgically or by stent placement. However, a decreased life expectancy associated with altered aortic hemodynamics was found in long-term studies. Image-based computational fluid dynamics (CFD) is intended to support particular diagnoses, to help in choosing between treatment options, and to improve performance of treatment procedures. This study aimed to prove the ability of CFD to improve aortic hemodynamics in CoA patients. In 13 patients (6 males, 7 females; mean age 25 ± 14 years), we compared pre- and post-treatment peak systole hemodynamics [pressure drops and wall shear stress (WSS)] vs. virtual treatment as proposed by biomedical engineers. Anatomy and flow data for CFD were based on MRI and angiography. Segmentation, geometry reconstruction and virtual treatment geometry were performed using the software ZIBAmira, whereas peak systole flow conditions were simulated with the software ANSYS(®) Fluent(®). Virtual treatment significantly reduced pressure drop compared to post-treatment values by a mean of 2.8 ± 3.15 mmHg, which significantly reduced mean WSS by 3.8 Pa. Thus, CFD has the potential to improve post-treatment hemodynamics associated with poor long-term prognosis of patients with coarctation of the aorta. MRI-based CFD has a huge potential to allow the slight reduction of post-treatment pressure drop, which causes significant improvement (reduction) of the WSS at the stenosis segment.

Background Intraperitoneal tumor cell attachment after resection of gastrointestinal cancer may lead to a developing of peritoneal carcinosis. Intraabdominal application of phospholipids shows a significant decrease of adhesion formation even in case of rising tumor cell concentration. Methods In experiment A 2*106 colonic tumor cells (DHD/K12/Trb) were injected intraperitonely in female BD-IX-rats. A total of 30 rats were divided into three groups with treatments of phospholipids at 6% or 9% and the control group. In experiment B a total of 100 rats were divided into ten groups with treatments of phospholipids at 9% and the control group. A rising concentration of tumor cells (10,000, 50,000, 100,000, 250,000 and 500,000) were injected intraperitonely in female BD-IX-rats of the different groups. After 30 days, the extent of peritoneal carcinosis was determined by measuring the tumor volume, the area of attachment and the Peritoneal Cancer Index (PCI). Results In experiment A, we found a significant reduction (control group: tumor volume: 12.0 ± 4.9 ml; area of tumor adhesion: 2434.4 ± 766 mm2; PCI 28.5 ± 10.0) of peritoneal dissemination according to all evaluation methods after treatment with phospholipids 6% (tumor volume: 5.2 ± 2.2 ml; area of tumor adhesion: 1106.8 ± 689 mm2; PCI 19.0 ± 5.0) and phospholipids 9% (tumor volume: 4.0 ± 3.5 ml; area of tumor adhesion: 362.7 ± 339 mm2; PCI 13.8 ± 5.1). In experiment B we found a significant reduction of tumor volume in all different groups of rising tumor cell concentration compared to the control. As detected by the area of attachment we found a significant reduction in the subgroups 1*104, 25*104 and 50*104. The reduction in the other subgroups shows no significance. The PCI could be reduced significantly in all subgroups apart from 5*104. Conclusion In this animal study intraperitoneal application of phospholipids resulted in reduction of the extent of peritoneal carcinomatosis after intraperitoneal administration of free tumor cells. This effect was exceptionally noticed when the amount of intraperitoneal tumor cells was limited. Consequently, intraperitoneal administration of phospholipids might be effective in reducing peritoneal carcinomatosis after surgery of gastrointestinal tumors in humans. PMID:17584925

Application of landfill treatment approaches for stabilization of municipal solid waste.

Bolyard, Stephanie C; Reinhart, Debra R

2016-09-01

This research sought to compare the effectiveness of three landfill enhanced treatment approaches aimed at removing releasable carbon and nitrogen after anaerobic landfilling including flushing with clean water (FB 1), leachate recirculation with ex-situ treatment (FB 2), and leachate recirculation with ex-situ treatment and in-situ aeration (FB 3). After extensive treatment of the waste in the FB scenarios, the overall solids and biodegradable fraction were reduced relative to the mature anaerobically treated waste. In terms of the overall degradation, aeration did not provide any advantage over flushing and anaerobic treatment. Flushing was the most effective approach at removing biodegradable components (i.e. cellulose and hemicellulose). Leachate quality improved for all FBs but through different mechanisms. A significant reduction in ammonia-nitrogen occurred in FB 1 and 3 due to flushing and aeration, respectively. The reduction of chemical oxygen demand (COD) in FB 1 was primarily due to flushing. Conversely, the reduction in COD in FBs 2 and 3 was due to oxidation and precipitation during Fenton's Reagent treatment. A mass balance on carbon and nitrogen revealed that a significant fraction still remained in the waste despite the additional treatment provided. Carbon was primarily converted biologically to CH4 and CO2 in the FBs or removed during treatment using Fenton's Reagent. The nitrogen removal occurred through leaching or biological conversion. These results show that under extensive treatment the waste and leachate characteristics did meet published stability values. The minimum stability values achieved were through flushing although FB 2 and 3 were able to improve leachate quality and solid waste characteristics but not to the same extent as FB 1.

Allergic rhinitis is usually treated with oral antihistamines or nasal steroids. Topically active nasal antihistamine is a new treatment modality for allergic rhinitis. The efficacy in comparison to well established topical treatment alternatives is not fully known. To compare the efficacy of intranasally administered azelastine to budesonide, at their respectively recommended dosage, on the symptoms of perennial rhinitis patients. A placebo-controlled, randomized, parallel group study was conducted to compare the efficacy and tolerability of intranasal budesonide aqueous suspension (256 microg once daily) with azelastine hydrochloride nasal spray (280 microg twice daily (560 microg/day)) and with placebo in the treatment of perennial allergic rhinitis. The 195 patients (with at least a 2-year history of perennial allergic rhinitis) recorded individual nasal symptom scores, the degree of symptom control achieved and any adverse events experienced over a 2-week baseline period and a 6-week treatment period. Following treatment, the reductions in mean combined and individual nasal symptom scores from baseline values were significantly greater in the budesonide group compared with the placebo group (P < .0001 for all variables except runny nose P = .01). In patients treated with budesonide, there were also significantly larger reductions from baseline values in combined nasal symptom scores (P < .01) and in scores for all individual nasal symptoms (P < or = .05) compared with those treated with azelastine. The reductions from baseline in both combined and individual nasal symptom scores did not differ between azelastine and placebo. The study medications were well tolerated, producing no unexpected or serious treatment-related adverse events. A once-daily dose of 256 microg of intranasal budesonide aqueous suspension is significantly more effective at relieving the symptoms of perennial allergic rhinitis compared with a twice daily dose of 280 microg of azelastine nasal spray.

2014-03-01

Mild Cognitive Impairment (MCI) and REM Behavior Disorder (RBD) are both associated with a degeneration of ponto-medullary cholinergic pathways. We conducted a placebo-controlled, cross-over pilot trial of Rivastigmine (RVT) in 25 consecutive patients with MCI, who presented RBD refractory to conventional first-line treatments (melatonin up to 5 mg/day and clonazepam up to 2 mg/day). RVT treatment was followed by a significant reduction of RBD episodes when compared with placebo. Our data suggest that, in MCI patients with RBD resistant to conventional therapies (muscle relaxants benzodiazepines or melatonin,) treatment with RVT may induce a reduction in the frequency of RBD episodes compared to placebo.

4D.10: CHANGES IN PWV IN PREVIOUSLY UNTREATED MILD HYPERTENSIVES ARE RELATED TO REDUCTION OF BLOOD PRESSURE BY TREATMENT.

Changes in target organ lesions, even beyond reduction of blood pressure, have been shown to have predictive value. Destiffening of arterial damage seems to be possible but the mechanisms are still elusive. We report changes in pulse wave velocity (PWV) after one year of treatment in new diagnosed previously untreated, hypertensive patients. We included in this longitudinal study 356 consecutive, never-treated patients with suspected hypertension. After standard clinical assessment, including ambulatory blood pressure monitoring (ABPM), pulse wave analysis and PWV (Sphygmocor®, AtcorMedical), 231 showed elevated office and/or ambulatory blood pressure (BP) and received monotherapy treatment accordingly. 125 patients who showed to be normotensive, served as control group. Clinical assessment was repeated after a median of 1.1 years in the whole cohort. PWV was adjusted to BP. In the whole group, 179 patients were female (50.3%), mean age was 48.8 ± 12years. The hypertensive diagnosed group tended to be older (50 vs. 46 years, p < 0,001) and had higher PWV even after mean BP adjustment (8.6 ± 2.0 vs. 8.0 ± 1.4 m/s, p < 0.001), higher baseline office, ambulatory and central BP (145/86, 136/86 and 138/87 mmHg vs. 125/75, 120/76 and 120/79, respectively, p < 0,001). After 1 year of treatment, BP was significantly improved only in the hypertensive group (follow-up office, ambulatory and central BP 128/75, 124/78, 121/79 mmHg, pintragroup < 0.001) and remained constant in the control group (126/74, 120/76, 120/80, pintragroup = ns). The reduction of central and peripheral systolic BP in the hypertensive group was of the same magnitude (-17 vs -17 mmHg, p = ns). PWV was significantly reduced in both groups even after BP adjustment, at follow-up they were similar between groups (7.8 vs. 7.7, p = ns). The reduction of adjusted PWV was significantly higher in the hypertensive group (Delta = 0.86 vs. 0,20 m/s, p = 0.001). There was no differential effect in PWV reduction depending on antihypertensive class, except for patients treated with nebivolol. Blood pressure reduction in newly diagnosed stage 1 hypertensive patients improves PWV within a year of treatment, confirming that rapid tight control of BP is important even in mild hypertensives. Of note, arterial destiffening seems to go beyond BP reductions.

Summary Background Unwanted submental fat (SMF) is aesthetically unappealing, but methods of reduction are either invasive or lack evidence for their use. An injectable approach with ATX-101 (deoxycholic acid) is under investigation. Objectives To evaluate the efficacy and safety of ATX-101 for the reduction of unwanted SMF. Methods In this double-blind, placebo-controlled, phase III study, 363 patients with moderate/severe SMF were randomized to receive ATX-101 (1 or 2 mg cm−2) or placebo injections into their SMF at up to four treatment sessions ∽28 days apart, with a 12-week follow-up. The co-primary efficacy endpoints were the proportions of treatment responders [patients with ≥ 1-point improvement in SMF on the 5-point Clinician-Reported Submental Fat Rating Scale (CR-SMFRS)] and patients satisfied with their face and chin appearance on the Subject Self-Rating Scale (SSRS). Secondary endpoints included skin laxity, calliper measurements and patient-reported outcomes. Adverse events were monitored. Results Significantly more ATX-101 recipients met the primary endpoint criteria vs. placebo: on the clinician scale, 59·2% and 65·3% of patients treated with ATX-101 1 and 2 mg cm−2, respectively, were treatment responders vs. 23·0% for placebo (CR-SMFRS;P < 0·001); on the patient scale, 53·3% and 66·1%, respectively, vs. 28·7%, were satisfied with their face/chin appearance (SSRS;P < 0·001). Calliper measurements showed a significant reduction in SMF (P < 0·001), skin laxity was not worsened and patients reported improvements in the severity and psychological impact of SMF with ATX-101 vs. placebo. Most adverse events were transient and associated with the treatment area. Conclusions ATX-101 was effective and well tolerated for nonsurgical SMF reduction. What's already known about this topic? Unwanted submental fat (SMF) is considered aesthetically unappealing. Liposuction and face-lift are effective treatments for SMF reduction but are invasive and not suitable for all patients, whereas nonsurgical alternatives lack robust clinical evidence related to their safety and efficacy. ATX-101, a proprietary formulation of synthetically derived deoxycholic acid, is the first nonsurgical treatment for SMF reduction to be investigated in randomized, placebo-controlled clinical studies. What does this study add? This study provides the first data from a large-scale, randomized, placebo-controlled, phase III study of an injectable therapy for SMF reduction in a field currently lacking a sound evidence base. ATX-101 was superior to placebo for the clinician- and patient-evaluated reduction of unwanted SMF and led to improved patient perception about their appearance. ATX-101 was well tolerated; treatment-associated adverse events were mainly transient and localized injection-site reactions. PMID:24147933

The effect of Neuragen PN® on Neuropathic pain: A randomized, double blind, placebo controlled clinical trial

PubMed Central

2010-01-01

Background A double blind, randomized, placebo controlled study to evaluate the safety and efficacy of the naturally derived topical oil, "Neuragen PN®" for the treatment of neuropathic pain. Methods Sixty participants with plantar cutaneous (foot sole) pain due to all cause peripheral neuropathy were recruited from the community. Each subject was randomly assigned to receive one of two treatments (Neuragen PN® or placebo) per week in a crossover design. The primary outcome measure was acute spontaneous pain level as reported on a visual analog scale. Results There was an overall pain reduction for both treatments from pre to post application. As compared to the placebo, Neuragen PN® led to significantly (p < .05) greater pain reduction. Fifty six of sixty subjects (93.3%) receiving Neuragen PN® reported pain reduction within 30 minutes. This reduction within 30 minutes occurred in only twenty one of sixty (35.0%) subjects receiving the placebo. In a break out analysis of the diabetic only subgroup, 94% of subjects in the Neuragen PN® group achieved pain reduction within 30 minutes vs 11.0% of the placebo group. No adverse events were observed. Conclusions This randomized, placebo controlled, clinical trial with crossover design revealed that the naturally derived oil, Neuragen PN®, provided significant relief from neuropathic pain in an all cause neuropathy group. Participants with diabetes within this group experienced similar pain relief. Trial registration ISRCTN registered: ISRCTN13226601 PMID:20487567

Multi-Case Knowledge-Based IMRT Treatment Planning in Head and Neck Cancer

NASA Astrophysics Data System (ADS)

Grzetic, Shelby Mariah

Head and neck cancer (HNC) IMRT treatment planning is a challenging process that relies heavily on the planner's experience. Previously, we used the single, best match from a library of manually planned cases to semi-automatically generate IMRT plans for a new patient. The current multi-case Knowledge Based Radiation Therapy (MC-KBRT) study utilized different matching cases for each of six individual organs-at-risk (OARs), then combined those six cases to create the new treatment plan. From a database of 103 patient plans created by experienced planners, MC-KBRT plans were created for 40 (17 unilateral and 23 bilateral) HNC "query" patients. For each case, 2D beam's-eye-view images were used to find similar geometric "match" patients separately for each of 6 OARs. Dose distributions for each OAR from the 6 matching cases were combined and then warped to suit the query case's geometry. The dose-volume constraints were used to create the new query treatment plan without the need for human decision-making throughout the IMRT optimization. The optimized MC-KBRT plans were compared against the clinically approved plans and Version 1 (previous KBRT using only one matching case with dose warping) using the dose metrics: mean, median, and maximum (brainstem and cord+5mm) doses. Compared to Version 1, MC-KBRT had no significant reduction of the dose to any of the OARs in either unilateral or bilateral cases. Compared to the manually planned unilateral cases, there was significant reduction of the oral cavity mean/median dose (>2Gy) at the expense of the contralateral parotid. Compared to the manually planned bilateral cases, reduction of dose was significant in the ipsilateral parotid, larynx, and oral cavity (>3Gy mean/median) while maintaining PTV coverage. MC-KBRT planning in head and neck cancer generates IMRT plans with better dose sparing than manually created plans. MC-KBRT using multiple case matches does not show significant dose reduction compared to using a single match case with dose warping.

Background and Aims: The lack of specificity has limited the role of serum alpha-fetoprotein (AFP) for hepatocellular carcinoma (HCC) screening among patients with cirrhosis related to hepatitis C virus (HCV) infection. We sought to examine whether AFP may decrease after achieving a sustained virological response (SVR) in patients with HCV-related cirrhosis. Methods: We performed a retrospective study of patients with HCV-related cirrhosis who were cured with direct-acting antiviral (DAA) therapy at the University of California, Los Angeles. Laboratory values, including serum AFP, were measured before and after completing the DAA treatment. Results: Fifty-six patients met the inclusion criteria, with median (interquartile range [IQR]) age of 67 (58-69) years and with 51.8% being male. All patients received DAA therapy without interferon. AFP decreased from median (IQR) 7.2 (4.2-13.4) ng/mL before DAAs to 4.2 (2.7-6.3) ng/mL at the end of treatment and 4.2 (2.9-6.8) ng/mL at 12 weeks after treatment ( p < 0.001). Model for end-stage liver disease (MELD), fibrosis-4 (FIB4), and aspartate transaminase (AST) to platelet ratio index (APRI) scores at baseline were not significantly associated with AFP reduction. On multivariate analysis, platelet count, AST and total bilirubin at baseline were significantly correlated to AFP reduction ( p = 0.04, 0.009 and 0.04, respectively). The higher the baseline AFP, the greater the reduction in AFP. There was no statistically significant correlation between baseline AFP and MELD, FIB4 or APRI scores. Conclusion: There was a significant decrease in AFP in patients with cirrhosis who achieved a SVR with DAAs. Given a reduction in AFP after DAA treatment, AFP should be further studied as a screening modality for HCC in patients with cirrhosis.

Effect of reductive treatments on Pt behavior and NOx storage in lean NOx trap catalysts

Lean NOx trap (LNT) catalysts represent a promising approach to meet increasingly stringent NOx emission regulations on diesel and other lean-burn engines. Pt material properties, including dispersion and particle size, are known to be important factors in determining NOx uptake performance, since Pt provides active sites for NO oxidation to NO2 necessary for storing NOx as nitrates, and for the reduction of nitrates to N2. In this work, the physicochemical properties of Pt in Pt-BaO/Al2O3 LNT catalysts, such as the Pt accessible surface area and particle size, were investigated by using various tools, such as irreversible volumetric H2 chemisorption, highmore » resolution transmission electron microscopy (HRTEM), and X-ray diffraction (XRD), following successive reductive treatments at elevated temperatures. NOx uptake activities were also measured to establish a relationship between the properties of Pt and NOx storage following identical high-temperature reductive treatments. We find that the reductive treatments of Pt-BaO/Al2O3 lean NOx trap catalysts at temperatures up to 500 ºC promote a significant increase in NOx uptake explained, in part, by an induced close interaction between Pt and BaO phases in the catalyst, thus enabling facilitation of the NOx storage process.« less

Background: Little is known about burden of chronic myeloid leukemia (CML) in India. There is a recent interest to observe incidence and mortality because of advent of new diagnostic and treatment policies for CML. Materials and Methods: We extracted data from the oldest population-based cancer registry of Mumbai for 30 years period from 1976−2005 to observe incidence and mortality rates of CML. We classified the data into four age groups 0–14, 15–29, 30–54 and 55–74 to observe incidence rates in the respective age groups. Results: The age specific rates were highest for the age group of 55–74 years. No significant change in trends of CML was observed for 30 years period. However, there was a significant reduction in incidence rate for recent 15-years period (Estimated average annual percentage change=-3.9). No significant reduction in mortality rate was observed till 2005. Conclusion: The study demonstrates that age-specific rates for CML are highest in age group of 55-74 years, although they are lower compared to western populations. Significant reduction in incidence of CML in recent periods might be because of reduced misclassification of leukemias. The data of CML has to be observed for another decade to witness reduction in mortality because of changes in treatment management. PMID:22174498

Endovascular treatment of paraclinoid aneurysms is preferred in clinical practice. Flow alterations caused by stents and coils may affect treatment outcome. To assess hemodynamic changes following stent-assisted coil embolization (SACE) in subtotally embolized paraclinoid aneurysms with residual necks that were predisposed to recanalization. We studied 27 paraclinoid aneurysms (seven recanalized and 20 stable) treated with coils and Enterprise stents. Computational fluid dynamic simulations were performed on patient-specific aneurysm geometries using virtual stenting and porous media technology. After stent placement in 27 cases, aneurysm flow velocity decreased significantly, the reduction gradually increasing from the neck plane (11.9%), to the residual neck (12.3%), to the aneurysm dome (16.3%). Subsequent coil embolization was performed after stent placement and the hemodynamic factors decreased further and significantly at all aneurysm regions except the neck plane. In a comparison of recanalized and stable cases, univariate analysis showed no significant differences in any parameter before treatment. After stent-assisted coiling, only the reduction in area-averaged velocity at the neck plane differed significantly between recanalized (8.1%) and stable cases (20.5%) (p=0.016). Aneurysm flow velocity can be significantly decreased by stent placement and coil embolization. However, hemodynamics at the aneurysm neck plane is less sensitive to coils. Significant reduction in flow velocity at the neck plane may be an important factor in preventing recanalization of paraclinoid aneurysms after subtotal SACE.

The primary objective of this study was to estimate a clinically significant and quantifiable change in functional disability to identify treatment responders in a clinical trial of cognitive-behavioral therapy (CBT) for youth with juvenile fibromyalgia (JFM). The second objective was to examine whether baseline functional disability (Functional Disability Inventory), pain intensity, depressive symptoms (Children's Depression Inventory), coping self-efficacy (Pain Coping Questionnaire), and parental pain history predicted treatment response in disability at 6-month follow-up. Participants were 100 adolescents (11-18 years of age) with JFM enrolled in a recently published clinical trial comparing CBT to a fibromyalgia education (FE) intervention. Patients were identified as achieving a clinically significant change in disability (i.e., were considered treatment responders) if they achieved both a reliable magnitude of change (estimated as a > or = 7.8-point reduction on the FDI) using the Reliable Change Index, and a reduction in FDI disability grade based on established clinical reference points. Using this rigorous standard, 40% of patients who received CBT (20 of 50) were identified as treatment responders, compared to 28% who received FE (14 of 50). For CBT, patients with greater initial disability and higher coping efficacy were significantly more likely to achieve a clinically significant improvement in functioning. Pain intensity, depressive symptoms, and parent pain history did not significantly predict treatment response. Estimating clinically significant change for outcome measures in behavioral trials sets a high bar but is a potentially valuable approach to improve the quality of clinical trials, to enhance interpretability of treatment effects, and to challenge researchers to develop more potent and tailored interventions.

Kratz, Mario T; Schirmer, Stephan H; Baumhäkel, Magnus; Böhm, Michael

2016-08-01

The renin-angiotensin-aldosterone-system (RAAS) plays a role in endothelial dysfunction and atherosclerosis. During treatment with RAAS-inhibitors, elevated aldosterone may sustain "aldosterone escape". We investigated the effects of treatment with the mineralocorticoid antagonist eplerenone (Ep) compared with ramipril (Rami) or the combination of both on oxidative stress, plaque formation and endothelial function, in atherosclerotic apolipoprotein E deficient mice (ApoE(-/-)-mice). ApoE(-/-)-mice were fed a cholesterol rich diet (21% fat, 19.5% casein, 1.25% cholesterol) for 8 weeks to produce mild atherosclerosis (i.e. plaque load 20-30%). ApoE(-/-)-mice (control), ApoE(-/-)-mice treated with Ep (25 mg/kg/day), Rami (2.5 mg/kg/day) and their combination were compared. Heart rate (HR) and blood pressure (BP) were measured using the tail-cuff-method. Endothelial function was measured in aortic rings and corpora cavernosal strips (CCs). Atherosclerotic plaque burden, collagen content, oxidative stress (Dihydroethidium (DHE) staining) and macrophages were determined. Treatments had no effects on HR and slightly reduced BP in ApoE(-/-)-mice treated with the combination of eplerenone and ramipril. Endothelium-dependent relaxation of aortic rings and CCs with carbachol was significantly improved in animals treated with Ep, Rami or their combination (p = 0.05 - p = 0.001). DHE-stained penile and aortic sections revealed a significant reduction in superoxide production in all treated groups (p = 0.035 - p = 0.001). In parallel, aortic and penile collagen content in ApoE(-/-)-mice was significantly decreased (p = 0.035 - p < 0.001) in animals treated with Ep, Rami or their combination. In agreement, there was a trend towards a reduction of aortic plaque area by treatment with Ep (-9.0 ± 3.2%) and Rami (-11.9 ± 4%). Only the treatment with the combination induced a significant reduction of the atherosclerotic plaque burden (p = 0.045). Moreover, the treatment of ApoE(-/-)-mice with Ep, Rami and their combination significantly reduced the count macrophage count in atherosclerotic plaque lesions. Ep restored endothelial function by reduction of oxidative stress, atherosclerotic macrophage content, atherosclerotic lesion size and fibrosis to the same extent as treatment with Rami or the combination. Mineralocorticoid antagonism provides vasculoprotective effects and should be clinically evaluated for vascular disease such as erectile dysfunction. Copyright © 2016 Elsevier Ireland Ltd.

Gastrointestinal symptoms are among the most frequent reported complaints by people living with HIV and AIDS (PLWHA). Treatments that aim to attenuate these symptoms are important to avoid low adherence to antiretroviral therapy and to improve the quality of life. This study aimed to evaluate the effectiveness of nutritional treatment and synbiotic use in PLWHA on reducing gastrointestinal symptoms. A randomized clinical trial nested to an outpatient cohort was conducted to evaluate the effectiveness of two treatments for gastrointestinal symptoms reduction in adult patients with antiretroviral therapy presenting at least one gastrointestinal symptom: 1) nutritional treatment + placebo (6 g maltodextrin) and 2) nutritional treatment + synbiotic (Lactobacillus and Bifidobacterium strains + 6 g fructooligosaccharides). Placebo and synbiotic were consumed twice a day during six months. The primary outcome variable was percentage reduction in the incidence of diarrhea, and secondary outcomes the decrease in the incidence of nausea and/or vomiting, dyspepsia, heartburn, constipation, flatulence, and the presence of three or more gastrointestinal symptoms. Out of 283 patients evaluated for eligibility, 64 met inclusion criteria to enter in this study with 1:1 allocation ratio. Both analyzed groups were homogeneous regarding sociodemographic, clinical and lifestyle variables at baseline. In the intergroup analysis, no difference was found between groups except for heartburn, which had a higher reduction in the placebo group (0.01). Regarding the intragroup analysis, in the placebo group a significant decrease in diarrhea (p = 0.02) and heartburn (p < 0.01) were observed while there was a significant reduction for nausea e/or vomit (p = 0.01), dyspepsia (p = 0.10), diarrhea (p = 0.01) and constipation (p = 0.08) in the synbiotic group. Diarrhea decreased in both groups, but no statistical difference between treatments was observed. The use of synbiotic appeared to reduce a greater number of symptoms although there were no statistical differences in the intergroup analysis.

There were a limited number of studies about β-cell function after insulin initiation in patients exposed to long durations of sulfonylurea treatment. In this study, we aimed to evaluate the recovery of β-cell function and the efficacy of concurrent sulfonylurea use after the start of long-acting insulin. In this randomized controlled study, patients with type 2 diabetes mellitus (T2DM), receiving sulfonylurea for at least 2 years with glycosylated hemoglobin (HbA1c) >7%, were randomly assigned to two groups: sulfonylurea maintenance (SM) and sulfonylurea reduction (SR). Following a 75-g oral glucose tolerance test (OGTT), we administered long-acting basal insulin to the two groups. After a 6-month follow-up, we repeated the OGTT. Among 69 enrolled patients, 57 completed the study and were analyzed: 31 in the SM and 26 in the SR group. At baseline, there was no significant difference except for the longer duration of diabetes and lower triglycerides in the SR group. After 6 months, the HbA1c was similarly reduced in both groups, but there was little difference in the insulin dose. In addition, insulin secretion during OGTT was significantly increased by 20% to 30% in both groups. A significant weight gain was observed in the SM group only. The insulinogenic index was more significantly improved in the SR group. Long-acting basal insulin replacement could improve the glycemic status and restore β-cell function in the T2DM patients undergoing sulfonylurea-based treatment, irrespective of the sulfonylurea dose reduction. The dose reduction of the concurrent sulfonylurea might be beneficial with regard to weight grain.

Septimeb as a herbal medicine has regulatory effects on inflammation. This study set to evaluate the effects of Septimeb among patients with sepsis on inflammatory biomarkers and survival rate. In this randomized clinical trial, 51 patients with sepsis from the ICU and medical ward of Imam Khomeini Hospital were divided into two groups: Septimeb (n=25) and control group (n=26). In the control group, the patients received a standard treatment only for 7 days, while Septimeb group received Septimeb (6cc vial with 500cc serum glucose infusion 5% daily for one to two hours) plus standard treatment of sepsis for 7 days. Then, blood samples were analyzed. APACHE (Acute Physiologic and Chronic Health Evaluation), SOFA (Sequential Organ Failure Assessment), and GCS (Glasgow Coma Score) values were calculated daily. Treatment with Septimeb showed a significant decrease in SOFA value (1.54±0.83) compared to the control group (2.39±0.88) (P<0.001) and a significant increase in GCS value (14.46±0.88) compared to the control group (12.86±1.78) (P<0.001). Improvements of these values can confirm the potential of Septimeb in the reduction of severity of sepsis (P<0.05). There were significant decreases in lactate and blood sugar and WBC levels. In addition, inflammatory factors such as ESR (Septimeb group: 52.07±34.80, control group: 51.75±42.10, P=0.98) and CRP (Septimeb group: 48.86±23.21, control group: 49.93±36.22, P=0.92) decreased, but did not show a significant reduction. Septimeb has positive effects on reduction of the severity of sepsis which leads to reduction of patients' mortality rates.

Various studies have shown periodontal disease is one of the risk factors for coronary heart disease (CHD), and periodontal treatment of patients with CHD has also been correlated with reduction in systemic markers of CHD. The aim of this study is to evaluate the effect of non-surgical periodontal treatment (NSPT) on the cardiovascular clinical and biochemical status of patients with CHD. Seventy known patients with CHD were allocated randomly to either a control group (C; no periodontal therapy) (n = 35) or an experimental group (E; NSPT in the form of scaling and root planing [SRP]) (n = 35). Cardiovascular status was assessed using clinical parameters such as pulse, respiratory rate, blood pressure (BP), and biochemical parameters, such as high-sensitivity C-reactive protein (hsCRP), lipid profile, and white blood cell (WBC) count, at baseline and 1, 3, and 6 months. Intergroup and intragroup comparisons were performed using Student t test, and P <0.05 was considered statistically significant. The complete data at the end of the study were provided by only 55 patients (group C, n = 25; group E, n = 30). Highly statistically significant reduction was observed in systolic BP (7.1 mm Hg) and very-low-density lipoproteins (VLDLs; 5.16 mg/dL) in group E. Changes were also observed in other cardiovascular biochemical and clinical parameters but were not statistically significant. NSPT (in the form of SRP) positively affects limited cardiovascular (clinical and biochemical) status of patients with CHD. Reduction in triglyceride, VLDL, total WBC, lymphocyte, and neutrophil counts and increase in hsCRP, total cholesterol, high-density lipoprotein, and low-density lipoprotein levels were observed. Highly significant reduction in VLDL cholesterol levels and systolic BP was observed among the various parameters measured.

Many countries are utilizing reclaimed wastewater for agriculture as water demands due to drought, rising temperatures, and expanding human populations. Unfortunately, wastewater often contains biologically active, pseudopersistant pharmaceuticals, even after treatment. Runoff from agriculture and effluent from wastewater treatment plants also contribute high concentrations of pharmaceuticals to the environment. This study assessed the effects of common pharmaceuticals on an agricultural pest, the aphid Myzus persicae (Sulzer, Hemiptera: Aphididae). Second instar nymphs were transferred to bell peppers (Capsicum annuum) that were grown hydroponically. Treatment plants were spiked with contaminants of emerging concern (CECs) at environmentally relevant concentrations found in reclaimed wastewater. M. persicae displayed no differences in population growth or microbial community differences due to chemical treatments. Plants, however, displayed significant growth reduction in antibiotic and mixture treatments, specifically in wet root masses. Antibiotic treatment masses were significantly reduced in the total and root wet masses. Mixture treatments displayed an overall reduction in plant root wet mass. Our results suggest that the use of reclaimed wastewater for crop irrigation would not affect aphid populations, but could hinder or delay crop production.

Cognitive-behavioural therapy (CBT) is an effective treatment for clinical and subclinical symptoms of depression and general anxiety, and increases life satisfaction. Patients' usage of CBT skills is a core aspect of treatment but there is insufficient empirical evidence suggesting that skills usage behaviours are a mechanism of clinical change. This study investigated if an internet-delivered CBT (iCBT) intervention increased the frequency of CBT skills usage behaviours and if this statistically mediated reductions in symptoms and increased life satisfaction. A two-group randomised controlled trial was conducted comparing internet-delivered CBT (n = 65) with a waitlist control group (n = 75). Participants were individuals experiencing clinically significant symptoms of depression or general anxiety. Mixed-linear models analyses revealed that the treatment group reported a significantly higher frequency of skills usage, lower symptoms, and higher life satisfaction by the end of treatment compared with the control group. Results from bootstrapping mediation analyses revealed that the increased skills usage behaviours statistically mediated symptom reductions and increased life satisfaction. Although skills usage and symptom outcomes were assessed concurrently, these findings support the notion that iCBT increases the frequency of skills usage behaviours and suggest that this may be an important mechanism of change.

To evaluate whether a mixed population of patients treated with Intensive Short-term Dynamic Psychotherapy (ISTDP) would exhibit reduced healthcare costs in long-term follow-up. A quasi-experimental design was employed in which data on pre- and post-treatment healthcare cost were compared for all ISTDP cases treated in a tertiary care service over a nine year period. Observed cost changes were compared with those of a control group of patients referred but never treated. Physician and hospital costs were compared to treatment cost estimates and normal population cost figures. 1082 patients were included; 890 treated cases for a broad range of somatic and psychiatric disorders and 192 controls. The treatment averaged 7.3 sessions and measures of symptoms and interpersonal problems significantly improved. The average cost reduction per treated case was $12,628 over 3 follow-up years: this compared favorably with the estimated treatment cost of $708 per patient. Significant differences were seen between groups for follow-up hospital costs. ISTDP in this setting appears to facilitate reductions in healthcare costs, supporting the notion that brief dynamic psychotherapy provided in a tertiary setting can be beneficial to health care systems overall.

Depression is prevalent in dementia and contributes to poor outcomes for patients and their families. Antidepressants have limited efficacy in older adults with major depression and dementia, and psychosocial interventions are under-investigated. To examine the course, predictors and moderators of depression and suicidal ideation during 12 weeks of home-delivered Problem Adaptation Therapy (PATH) versus Supportive Therapy for Cognitively Impaired Older Adults (ST-CI) in 39 older adults with major depression and dementia. Thirty-nine older adults with major depression, mild or moderate dementia, and disability participated in a randomized controlled trial that compared the efficacy of PATH versus ST-CI. Depression and suicidal ideation were assessed with Cornell Scale for Depression in Dementia Total Score and Suicide Item. PATH participants had significantly greater reduction in depression than ST-CI participants over 12 weeks of treatment. PATH participants with high social support had the greatest reduction in depression. Both treatments had comparable reduction in suicidal ideation. PATH is more effective in reducing depression in older adults with major depression and dementia compared to ST-CI. These results are clinically significant as antidepressants have limited efficacy in this population. Home-delivered psychosocial treatments may reduce suicidal ideation in this population.

Mild traumatic brain injury (mTBI) is a leading cause of sustained impairments in military service members, Veterans, and civilians. However, few treatments are available for mTBI, partially because the mechanism of persistent mTBI deficits is not fully understood. We used magnetoencephalography (MEG) to investigate neuronal changes in individuals with mTBI following a passive neurofeedback-based treatment programme called IASIS. This programme involved applying low-intensity pulses using transcranial electrical stimulation (LIP-tES) with electroencephalography monitoring. Study participants included six individuals with mTBI and persistent post-concussive symptoms (PCS). MEG exams were performed at baseline and follow-up to evaluate the effect of IASIS on brain functioning. At the baseline MEG exam, all participants had abnormal slow-waves. In the follow-up MEG exam, the participants showed significantly reduced abnormal slow-waves with an average reduction of 53.6 ± 24.6% in slow-wave total score. The participants also showed significant reduction of PCS scores after IASIS treatment, with an average reduction of 52.76 ± 26.4% in PCS total score. The present study demonstrates, for the first time, the neuroimaging-based documentation of the effect of LIP-tES treatment on brain functioning in mTBI. The mechanisms of LIP-tES treatment are discussed, with an emphasis on LIP-tES's potentiation of the mTBI healing process.

The aim of the study was to assess the 6-months treatment efficacy and 24-month follow up of three different therapeutic programs (A. moclobemide and supportive guidance, B. group cognitive-behavioral therapy and pill placebo, and C. combination of moclobemide and group cognitive-behavioral therapy) in patients with a generalized form of social phobia. Eighty one patients (38 males and 43 females) were randomly assigned to three different therapeutic programs. Patients were regularly assessed on a monthly basis by an independent rater on the LSAS (Liebowitz Social Anxiety scale), CGI (Clinical Global Impression) for severity and change and BAI (Beck Anxiety Inventory). Altogether, sixty-six patients completed the six month treatment period and 15 patients dropped out. All therapeutic groups showed significant improvement. A combination of CBT and pharmacotherapy yielded the most rapid effect. Moclobemide was superior for the reduction of the subjective general anxiety (BAI) during the first 3 months of treatment, but its influence on avoidant behavior (LSAS avoidance subscale) was less pronounced. Conversely, CBT was the best choice for reduction of avoidant behavior while a reduction of subjective general anxiety appeared later than in moclobemide. After 6 months of treatment there were best results reached in groups treated with CBT and there was no advantage of the combined treatment. The relapse rate during the 24-month follow up was significantly lower in the group treated with CBT in comparison with the group A. formerly treated with moclobemide alone.

Major depressive disorder (MDD) is a common and debilitating condition that can be challenging to treat. Electroconvulsive therapy (ECT) is currently the therapeutic gold standard for treatment-resistant MDD. We tested our hypothesis that ketamine-based anesthesia for ECT results in superior improvement in treatment-resistant MDD outcomes compared with propofol-based anesthesia. Patients with treatment-resistant MDD were enrolled in a randomized clinical trial with assignment to ketamine- or propofol-based anesthesia arms. Using a modified intention-to-treat analysis, we compared the median number of ECT treatments required to achieve a 50% reduction (primary outcome) and a score ≤ 10 (secondary outcome) on the Montgomery-Asberg depression rating scale (MADRS) between anesthesia groups. The study was terminated as significant results were found after the first planned interim analysis with 12 patients in each of the ketamine (intervention) and propofol (control) groups. All ketamine patients achieved at least a 50% MADRS reduction after a median of two ECT treatments whereas ten propofol patients (83%) achieved the same outcome after a median of four ECT treatments. All ketamine patients and seven propofol patients (58%) achieved MDD remission (MADRS ≤ 10). Log rank tests showed that both time-to-50% reduction and remission differed significantly between groups. Adverse events and recovery time were similar between groups. In this early-terminated small-sized study, ketamine-based anesthesia compared with propofol-based anesthesia provided response and remission after fewer ECT sessions. www.clinicaltrials.gov (NCT01935115).

Pathogen reduction of blood components.

PubMed

Solheim, Bjarte G

2008-08-01

Thanks to many blood safety interventions introduced in developed countries the risk of transfusion transmitted infections has become exceedingly small in these countries. However, emerging pathogens still represent a serious challenge, as demonstrated by West Nile virus in the US and more recently by Chikungunya virus in the Indian Ocean. In addition bacterial contamination, particularly in platelets, and protozoa transmitted by blood components still represent sizeable risks in developed countries. In developing countries the risk of all transfusion transmitted infections is still high due to insufficient funding and organisation of the health service. Pathogen reduction of pooled plasma products has virtually eliminated the risk of transfusion transmitted infections, without compromising the quality of the products significantly. Pathogen reduction of blood components has been much more challenging. Solvent detergent treatment which has been so successfully applied for plasma products dissolves cell membranes, and can, therefore, only be applied for plasma and not for cellular blood components. Targeting of nucleic acids has been another method for pathogen inactivation of plasma and the only approach possible for cellular blood products. As documented in more than 15 year's track record, solvent detergent treatment of pooled plasma can yield high quality plasma. The increased risk for contamination by unknown viruses due to pooling is out weighed by elimination of TRALI, significant reduction in allergic reactions and standardisation of the product. Recently, a promising method for solvent detergent treatment of single donor plasma units has been published. Methylene blue light treatment of single donor plasma units has a similar long track record as pooled solvent detergent treated plasma; but the method is less well documented and affects coagulation factor activity more. Psoralen light treated plasma has only recently been introduced (CE marked in Europe, but not licensed by the FDA), while the method of Riboflavin light treatment of plasma still is under development. In addition to pathogen reduction the methods, however, result in some reduction of coagulation factor activity. For platelets only Psoralen and Riboflavin light treatment have been implemented. Both are CE marked products in Europe but only approved for clinical trials in the USA. The methods affect platelet activity, but result in clinically acceptable platelets with only slightly reduced CCI and increased demand for platelet transfusions. Pathogen reduction of red blood cells with FRALE (S-303) or INACTINE (PEN110) has so far resulted in the formation of antibodies against neo-epitopes on red blood cells. A promising method for Riboflavin treatment of red blood cells is under development. This manuscript reviews the current experience and discusses future trends.

This study examined coping and general psychopathology as possible predictors of reduction of eating disorder symptomatology. Assessment took place at pre- and post-treatment for all eating disorder patients (N = 93). Eating pattern and behavior were measured, as well as BMI and general psychopathology. As hypothesized, the coping strategies and comorbidity of respondents at pre-treatment contributed significantly to their outcome scores, and behavior aspects associated with eating disorders. Active coping strategies and low levels of general psychopathology predicted better outcome scores. This implies that active coping strategies and low levels of accompanying psychopathology at pre-treatment could be indicators of good chances for reduction of eating disorder symptomatology such as emotional eating, bulimia symptomatology, ineffectiveness, and introceptive awareness.

In recent years, there has been growing research interest in using nicotine replacement medications to aid smoking reduction prior to a quit attempt. Gaining a better understanding of how treatments influence smoking reduction may allow for better tailoring of treatments and, ultimately, better cessation outcomes. The objective of the current study was to test the effects of the pre-quit use of varenicline and nicotine patch on smoking rate and satisfaction with smoking. All participants were required to attend up to five study visit sections. Participants (n = 213) who were interested in quitting were randomised (open-label) to receive either pre-quit patch or varenicline (both treatments started 2 weeks prior to an assigned quit day, followed by 10 weeks post-quit) or standard patch (10 weeks starting from an assigned quit day). Participants used modified smartphones to monitor their smoking in real time for 4 weeks. Participants in the two pre-quit treatment groups reported significant reductions in both their satisfaction with smoking (p < 0.001) and smoking rate (p < 0.001) from baseline to the end of pre-quit period; participants in the standard patch group did not. The observed reduction of smoking rate was associated with the satisfaction with smoking (p < 0.01), although the mediation effect of satisfaction was small. Pre-quit treatment caused reductions in satisfaction with smoking and smoking rate. Satisfaction was associated with changes in smoking rate, but the relationship was weak. As such, monitoring reductions in satisfaction do not appear to be a viable method of evaluating responsiveness to treatment.

Influenza is an important cause of morbidity and mortality for frail older people. Whilst the antiviral drug oseltamivir (a neuraminidase inhibitor) is approved for treatment and prophylaxis of influenza during outbreaks, there have been no trials comparing treatment only (T) versus treatment and prophylaxis (T&P) in Aged Care Facilities (ACFs). Our objective was to compare a policy of T versus T&P for influenza outbreaks in ACFs. We performed a cluster randomised controlled trial in 16 ACFs, that followed a policy of either "T"-oseltamivir treatment (75 mg twice a day for 5 days)-or "T&P"-treatment and prophylaxis (75 mg once a day for 10 days) for influenza outbreaks over three years, in addition to enhanced surveillance. The primary outcome measure was the attack rate of influenza. Secondary outcomes measures were deaths, hospitalisation, pneumonia and adverse events. Laboratory testing was performed to identify the viral cause of influenza-like illness (ILI) outbreaks. The study period 30 June 2006 to 23 December 2008 included three southern hemisphere winters. During that time, influenza was confirmed as the cause of nine of the 23 ILI outbreaks that occurred amongst the 16 ACFs. The policy of T&P resulted in a significant reduction in the influenza attack rate amongst residents: 93/255 (36%) in residents in T facilities versus 91/397 (23%) in T&P facilities (p=0.002). We observed a non-significant reduction in staff: 46/216 (21%) in T facilities versus 47/350 (13%) in T&P facilities (p=0.5). There was a significant reduction in mean duration of outbreaks (T=24 days, T&P=11 days, p=0.04). Deaths, hospitalisations and pneumonia were non-significantly reduced in the T&P allocated facilities. Drug adverse events were common but tolerated. Our trial lacked power but these results provide some support for a policy of "treatment and prophylaxis" with oseltamivir in controlling influenza outbreaks in ACFs.

Conventional drug treatments for Generalized Anxiety Disorder (GAD) are often accompanied by substantial side effects, dependence, and/or withdrawal syndrome. A prior controlled study of oral chamomile (Matricaria chamomilla L.) extract showed significant efficacy versus placebo, and suggested that chamomile may have anxiolytic activity for individuals with GAD. We hypothesized that treatment with chamomile extract would result in a significant reduction in GAD severity ratings, and would be associated with a favorable adverse event and tolerability profile. We report on the open-label phase of a two-phase randomized controlled trial of chamomile versus placebo for relapse-prevention of recurrent GAD. Subjects with moderate to severe GAD received open-label treatment with pharmaceutical-grade chamomile extract 1500mg/day for up to 8 weeks. Primary outcomes were the frequency of clinical response and change in GAD-7 symptom scores by week 8. Secondary outcomes included the change over time on the Hamilton Rating Scale for Anxiety, the Beck Anxiety Inventory, and the Psychological General Well Being Index. Frequency of treatment-emergent adverse events and premature treatment discontinuation were also examined. Of 179 subjects, 58.1% (95% CI: 50.9% to 65.5%) met criteria for response, while 15.6% prematurely discontinued treatment. Significant improvement over time was also observed on the GAD-7 rating (β=-8.4 [95% CI=-9.1 to -7.7]). A similar proportion of subjects demonstrated statistically significant and clinically meaningful reductions in secondary outcome ratings of anxiety and well-being. Adverse events occurred in 11.7% of subjects, although no serious adverse events occurred. Chamomile extract produced a clinically meaningful reduction in GAD symptoms over 8 weeks, with a response rate comparable to those observed during conventional anxiolytic drug therapy and a favorable adverse event profile. Future comparative effectiveness trials between chamomile and conventional drugs may help determine the optimal risk/benefit of these therapies for patients suffering from GAD.

Effective pain management remains a challenge for adolescents during conscious burn wound care procedures. Virtual reality (VR) shows promise as a non-pharmacological adjunct in reducing pain. This study assessed off-the-shelf VR for (1) its effect on reducing acute pain intensity during adolescent burn wound care, and (2) its clinical utility in a busy hospital setting. Forty-one adolescents (11-17 years) participated in this prospective randomized controlled trial. Acute pain outcomes including adolescent self-report, nursing staff behavioral observation, caregiver observation and physiological measures were collected. Length of procedure times and adolescent reactions were also recorded to inform clinical utility. Nursing staff reported a statistically significant reduction in pain scores during dressing removal, and significantly less rescue doses of Entonox given to those receiving VR, compared to those receiving standard distraction. For all other pain outcomes and length of treatment, there was a trend for lower pain scores and treatment times for those receiving VR, but these differences were not statistically significant. Despite only minimal pain reduction achieved using off-the-shelf VR, other results from this trial and previous research on younger children with burns suggest a customized, adolescent and hospital friendly device may be more effective in pain reduction.

The purpose of the present clinical study was to evaluate the effect of guided tissue regeneration (GTR) in comparison to subpedicle connective tissue graft (SCTG) in the treatment of gingival recession defects. A total of 12 patients, each contributing a pair of Miller's Class I or II buccal gingival recessions, was treated. According to a randomization list, one defect in each patient received a polyglycolide/lactide bioabsorbable membrane, while the paired defect received a SCTG. Treatment effect was evaluated 6 months postsurgery. Clinical recordings included full-mouth and defect-specific oral hygiene standards and gingival health, recession depth (RD), recession width (RW), probing depth (PD), clinical attachment level (CAL), and keratinized tissue width (KT). Mean RD significantly decreased from 3.1 mm presurgery to 1.5 mm at 6 months postsurgery for the GTR group (48% root coverage), and from 3.0 mm to 0.5 mm for the SCTG group (81% root coverage). RD reduction and root coverage were significantly greater in SCTG group compared to GTR group. Mean CAL gain amounted to 1.7 mm for the GTR group, and 2.3 mm in the SCTG group. No significant differences in PD changes were observed within and between groups. KT increased significantly from presurgery for both treatment groups, however gingival augmentation was significantly greater in the SCTG group compared to GTR group. Results indicate that: 1) treatment of human gingival recession defects by means of both GTR and SCTG procedures results in clinically and statistically significant improvement of the soft tissue conditions of the defect; and 2) treatment outcome was significantly better following SCTG compared to GTR in terms of recession depth reduction, root coverage, and keratinized tissue increase.

This randomized, controlled, double-blind clinical study in parallel groups evaluated the safety and efficacy of an oral combination diclofenac-cholestyramine, nucleotides (uridine and cytidine) and vitamin B12 versus the oral combination of nucleotides and vitamin B12 in the treatment of acute, non-traumatic pain. Subjects received twice-daily, 10-day oral administration of diclofenac-cholestyramine + uridine + cytidine + vitamin B12 (Group DN, n=40) or uridine + cytidine + vitamin B12 (Group NB, n=41). The primary study endpoint was the number of subjects with VAS reduction of >30mm after 10 days of treatment. Secondary endpoints included the number of patients with improvement >5 points in the Patient Functionality Questionnaire after 10 days of treatment, and the number of subjects presenting adverse events. Treatment with the combination of diclofenac-cholestyramine, nucleotides and Vitamin B12 resulted in a higher number of subjects with VAS score reductions >30mm after 10 days of treatment (87.5% subjects) than in the control group administered nucleotides and Vitamin B12 (51.23% of subjects), (p>0.0006). A significantly higher number of subjects in the DN group (80%) had a score reduction of >5 points in the Patient Functionality Questionnaire at after 10 days of treatment compared to Group NB (29.3%), (p<0.001). The number of subjects presenting AEs did not vary significantly between treatment groups (p=0.587). The combination of diclofenac-cholestyramine with uridine, cytidine and vitamin B12 was well-tolerated over a 10-day treatment period. The combination reduced pain and improved functionality among subjects presenting acute, non-traumatic pain in the lower back, hips, and neck.

Access to opioid agonist treatment can be associated with extensive waiting periods with significant health and financial burdens. This study aimed to determine whether patients with heroin dependence dispensed buprenorphine-naloxone weekly have greater reductions in heroin use and related adverse health effects 12-weeks after commencing treatment, compared to waitlist controls and to examine the cost-effectiveness of this strategy. An open-label waitlist RCT was conducted in an opioid treatment clinic in Newcastle, Australia. Fifty patients with DSM-IV-TR heroin dependence (and no other substance dependence) were recruited. The intervention group (n=25) received take-home self-administered sublingual buprenorphine-naloxone weekly (mean dose, 22.7±5.7mg) and weekly clinical review. Waitlist controls (n=25) received no clinical intervention. The primary outcome was heroin use (self-report, urine toxicology verified) at weeks four, eight and 12. The primary cost-effectiveness outcome was incremental cost per additional heroin-free-day. Outcome data were available for 80% of all randomized participants. Across the 12-weeks, treatment group heroin use was on average 19.02days less/month (95% CI -22.98, -15.06, p<0.0001). A total 12-week reduction in adjusted costs including crime of $A5,722 (95% CI 3299, 8154) in favor of treatment was observed. Excluding crime, incremental cost per heroin-free-day gained from treatment was $A18.24 (95% CI 4.50, 28.49). When compared to remaining on a waitlist, take-home self-administered buprenorphine-naloxone treatment is associated with significant reductions in heroin use for people with DSM-IV-TR heroin dependence. This cost-effective approach may be an efficient strategy to enhance treatment capacity. Crown Copyright © 2017. Published by Elsevier B.V. All rights reserved.

Due to the clinical challenges of treatment-resistant depression (TRD), we evaluated the efficacy of mindfulness-based cognitive therapy (MBCT) relative to a structurally equivalent active comparison condition as adjuncts to treatment-as-usual (TAU) pharmacotherapy in TRD. This single-site, randomized controlled trial compared 8-week courses of MBCT and the Health Enhancement Program (HEP), comprising physical fitness, music therapy and nutritional education, as adjuncts to TAU pharmacotherapy for outpatient adults with TRD. The primary outcome was change in depression severity, measured by percent reduction in the total score on the 17-item Hamilton Depression Rating Scale (HAM-D17), with secondary depression indicators of treatment response and remission. We enrolled 173 adults; mean length of a current depressive episode was 6.8 years (SD = 8.9). At the end of 8 weeks of treatment, a multivariate analysis showed that relative to the HEP condition, the MBCT condition was associated with a significantly greater mean percent reduction in the HAM-D17 (36.6 vs. 25.3%; p = 0.01) and a significantly higher rate of treatment responders (30.3 vs. 15.3%; p = 0.03). Although numerically superior for MBCT than for HEP, the rates of remission did not significantly differ between treatments (22.4 vs. 13.9%; p = 0.15). In these models, state anxiety, perceived stress and the presence of personality disorder had adverse effects on outcomes. MBCT significantly decreased depression severity and improved treatment response rates at 8 weeks but not remission rates. MBCT appears to be a viable adjunct in the management of TRD. © 2016 S.

An infusion of Campomanesia xanthocarpa Berg. (Myrtaceae) leaves (Guabiroba) and the herb Cuphea carthagenensis (Jacq.) J.F. Macbr. (Lythraceae) (Sete-sangrias) is traditionally used in the South of Brazil to treat high levels of cholesterol and triglycerides. The effects of the aqueous extracts of these herbs were investigated in rats fed on a high calorie diet. Chronic treatment with the Guabiroba aqueous extract induced a significant reduction in weight gain in the rats, compared to the control group. Also, biochemical analysis showed that this treatment reduced the glycemia, while no effects on lipidic levels were observed. The biochemical analysis of the animals treated with Sete-sangrias aqueous extract showed no effect on glucose and triglyceride levels, while chronic treatment with the Sete-sangrias aqueous extract induced a significant reduction in plasma cholesterol in rats.

The reductions of dissolved organic matter (DOM) and disinfection byproduct precursors in four full-scale wastewater treatment plants (WWTPs) (Liaoning Province, China) where different biological treatment processes were employed in winter were investigated. The total removal efficiencies of dissolved organic carbon (DOC), ultraviolet light at 254 nm (UV-254), trihalomethane formation potential (THMFP), and haloacetic acid formation potential (HAAFP) were in the range of 70.3-76.0%, 49.6-57.3%, 54.4-65.0%, and 53.7-63.8% in the four WWTPs, respectively. The biological treatment was the predominant process responsible for the removal of DOC, THMFP, and HAAFP in WWTPs. Differences in the reduction of UV-254 were not significant (p > 0.05) among biochemical reaction pool, secondary sedimentation tank, and disinfection tank. Biological aerated filter and suspended carrier activated sludge processes achieved higher DOM removal than the conventional active sludge and anaerobic-anoxic-oxic processes. Hydrophobic neutral and hydrophilic fraction were removed to a higher degree through biological treatment than the other three DOM fractions. HAAFP removal was more efficient than THMFP reduction during biological treatment. During primary treatment, fluorescent materials in secondary sedimentation tanks were preferentially removed, as compared to the bulk DOM. Humic-like fluorescent compounds were not readily eliminated during biological treatment. The fluorescent materials were more susceptible to chlorine than nonfluorescent compounds. Copyright © 2017.

Skin aging occurs through both intrinsic and extrinsic processes. Fractional radiofrequency (RF) with a microneedling array is the newest form of fractional therapy to be useful in treating aging skin. The current study utilized a noninsulated fractional RF microneedling system. This multicenter clinical trial saw 49 patients complete 3 monthly treatments with the new fractional RF microneedling treatments and be followed for 3 months following their last treatment. Pain during treatment was recorded as well as overall improvement using a GAIS scale. Adverse events were also noted. Forty-nine patients completed all of the treatments and follow-ups. Mild to moderate erythema were reported immediately after treatment which lasted up to 12 hours after the treatment. Pain, as measured on a 1-10 VAS, was noted to 4, on average. The average Fitzpatrick's wrinkle scale score at baseline was 5.04 ± 1.22, 1 month after 3 treatments 3.829 ± 1.69 and 3 months after 3 treatments 3.5 ± 1.66. These results are statistically highly significant (correlated T-test, P < 0.001). Improvement was shown in 100% of patients while 65% of patients had significant improvement (GAIS levels 3-5). Significant skin tightening and skin lifting were also observed. No unusual adverse events were noted throughout the course of the study. This multicenter study showed significant wrinkle reduction, skin tightening, and lifting of the mid and lower face with the noninsulated fractional RF microneedling system. Lasers Surg.

Purpose: To evaluate the effect of oral calcium dobesilate (Doxium) on macular thickness in clinically significant macular edema (CSME). Methods: Overall, 71 eyes of 40 patients with non-proliferative diabetic retinopathy and clinically significant macular edema were included. All patients were received laser treatment for macular edema. Coherence optical tomography was used to determine the retinal thickness. Patients were randomized into two groups: group A received three Doxium capsule daily and group B received three placebo capsule daily for six months. Results: The mean macular thickness before and after treatment in the group A was 340 and 257 micrometers respectively (24.5% reduced), and in the group B was 336 micrometers and 263 micrometers respectively (21.5% reduced). Macular thickness significantly decreased after treatment in both groups and the reduction in group A is higher but the difference of reduction between the two groups was not statistically significant (P>0.05). Conclusion: In respect to the effect of adding oral Doxium to Laser Photocoagulation on the macular thickness in patients with diabetic macular edema, this study showed no statistically significant difference between Doxium and placebo.

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.

Gastroesophageal reflux recommended treatment (dose and duration) with proton-pump inhibitor (PPI) compared to placebo significantly reduces the signs and symptoms of laryngopharyngeal reflux (LPR) and comorbid chronic rhinosinusitis (CRS). Double-blind randomised placebo-controlled trial. Eight weeks of treatment with omeprazole 20 mg once daily (OD). Sixty patients (28 women, aged 19-87 years) with diagnosed LPR and comorbid CRS. Significant reduction in signs and symptoms (reflux symptom index (RSI) score as subjective, and reflux finding score (RFS) as objective measure) of LPR after 8 weeks of treatment with omeprazole 20 mg OD when compared to placebo. Secondary objectives were significant reduction in signs and symptoms of comorbid CRS after 8 weeks of treatment with omeprazole 20 mg OD when compared to placebo and the association of the severity of signs and symptoms of LPR with the ones of CRS. RSI and RFS decreased significantly more in the active treatment group after 8 weeks compared to placebo (P < .001 for both). CRS and endoscopy scoring decreased both significantly more in the active group after 8 weeks compared to placebo (P < .001 for both). CRS scoring significantly correlated with RSI (R = 0.312, P = .015) but not with RFS (R = 0.199, P = .127). The results of our trial suggest that omeprazole 20 mg OD for 8 weeks was effective in reducing signs and symptoms of both LPR and CRS, although in most patients still present at the end of the trial. © 2017 John Wiley & Sons Ltd.

Thirty three chronic psychiatric hospital subjects with oral tardive dyskinesia were divided into three groups. The subjects were matched for severity of symptoms then randomly assigned to treatment with a placebo, 1 g deanol or 2 g deanol per day. Statistical analysis showed that after 30 days treatment, there was a significant reduction in the mean rating of the movements of the group of 11 subjects on 2 g deanol per day. Six of these subjects showed substantial reduction in movement. Further studies using this dosage of deanol are unwarranted.

To explore therapeutic effects of bone setting manipulation for the treatment of over degree II supination-eversion fractures of ankle,and analyze manipulative reduction mechanism. From 2005 to 2008, 95 patients with over degree II supination-eversion fractures of ankle were treated respectively by manipulation and operation. There were 43 cases [11 males and 32 females with an average age of (44.95 +/- 12.65) years] in manipulation group, and 2 cases were degree II, 11 cases were degree III, and 30 cases were degree IV. There were 52 cases [21 males and 31 females with an average age of (39.96 +/- 13.28) years] in operative group,and 6 cases were degree II, 18 cases were degree III, and 28 cases were degree IV. Bone setting manipulation and hard splint external fixation were applied to manipulative group. Operative reduction internal fixation was performed in operative group. X-ray was used to evaluate reduction of fracture before and after treatment, 2 months after treatment. Ankle joint function was evaluated according to Olerud-Molander scoring system after 6 months treatment. All patients were followed up with good reduction. Three cases occurred wound complication in operative group, but not in manipulative group. In manipulation group, 19 cases got excellent results, 20 cases good and 4 cases fair; while in operative group, 30 cases got excellent results, 20 cases good and 2 cases poor. There were no significant differences in fracture reduction and ankle joint function recovery between two groups (P > 0.05). Efficacy of operative treatment was better than that of manipulative treatment at degree IV fracture (P < 0.05). Bone setting manipulation is a good method for treating supination-eversion ankle joint fractures, which has advantages of simple and safe operation, reliable efficacy. For ankle join fracture at degree IV, manipulative reduction should be adopted earlier, and operative treatment also necessary

Novel multi-source phase-controlled radiofrequency technology for non-ablative and micro-ablative treatment of wrinkles, lax skin and acne scars.

The basic properties of lasers and pulsed light sources limit their ability to deliver high energy to the dermis and subcutaneous tissues without excessive damage to the epidermis. Radiofrequency was shown to penetrate deeper than optical light sources independent of skin color. The early RF-based devices used single source bipolar RF, which is safe but limited in use due to the superficial flow of energy between the two bipolar electrodes. Another type of single source RF employs a single electrode (monopolar) in which the RF energy flows from one electrode on the surface of the skin through the entire body to a plate under the body. Although more effective than bipolar, this devices require intense active cooling of the skin and may be associated with considerable pain and other systemic and local safety concerns. Latest generation of RF technology developed by EndyMed Medical Ltd. (Caesarea, Israel) utilizes simultaneously six or more phase controlled RF generators (3DEEP technology). The multiple electrical fields created by the multiple sources "repel" or "attract" each other, leading to the precise 3 dimensional delivery of RF energy to the dermal and sub-dermal targets minimizing the energy flow through the epidermis without the need for active cooling. Confocal microscopy of the skin has shown that 6 treatment sessions of Multisource RF technology improve skin structure features. The skin after treatment had longer and narrower dermal papilla and denser and finer collagen fiber typical to younger skin as compared to pre treatment skin. Ultrasound of the skin showed after 6 treatment sessions reduction of 10 percent in the thickness of the subcutaneous fat layer. Non ablative facial clinical studies showed a significant reduction of wrinkles after treatment further reduced at 3 months follow-up. Body treatment studies showed a circumference reduction of 2.9 cm immediately after 6 treatments, and 2 cm at 12 months after the end of treatment, proving long term collagen remodeling effect. Clinical studies of the multisource fractional RF application have shown significant effects on wrinkles reduction and deep atrophic acne scars after 1-3 treatment sessions.

Electronic cigarette (EC) use is growing dramatically with use highest among young adults and current smokers. One of the most common reasons for using ECs is interest in quitting or reducing cigarettes per day (CPD); however there are few randomized controlled trials (RCT) on the effect of ECs on smoking abstinence and reduction. We conducted a two-arm; double-blind RCT. Subjects were randomized to receive 3-weeks of either disposable 4.5% nicotine EC (intervention) or placebo EC. The primary outcome was self-reported reduction of at least 50% in the number of CPDs smoked at week 3 (end of treatment) compared to baseline. Study subjects (n = 99) were young adult (21-35), current smokers (smoked ≥ 10 CPDs) living in NYC. Compared with baseline, a significant reduction in CPDs was observed at both study time periods (1 and 3 weeks) for intervention (P < .001) and placebo (P < .001) groups. Between-group analyses showed significantly fewer CPDs in the intervention group compared to the placebo group at week 3 (P = .03), but not at any other follow-up periods. The logistic regression analysis showed that using a greater number of ECs, treatment condition and higher baseline readiness to quit were significantly associated with achieving at least 50% reduction in CPDs at the end of treatment. A diverse young adult sample of current everyday smokers, who were not ready to quit, was able to reduce smoking with the help of ECs. Further study is needed to establish the role of both placebo and nicotine containing ECs in increasing both reduction and subsequent cessation. Despite the critical need for well-designed clinical trials on the effect of ECs on cessation and cigarette reduction, the majority of studies have been observational or noncomparative intervention designs. Only three RCTs studying ECs as a cessation or reduction intervention have been published, and none were conducted in the United States. The current study adds knowledge to current literature on the feasibility of using ECs to aid smoking reduction among young smokers in US urban populations. © The Author 2016.

Megasessions: Efficacy of Fewer, Longer Treatment Sessions for Fat Reduction in Noninvasive Body Contouring Using a Radiofrequency Based Device.

PubMed

Duncan, Diane

2017-05-01

While the field of noninvasive body contouring is booming, many patients still note a lesser result than they might achieve with a single session of liposuction or dermolipectomy. The duration of a noninvasive fat reduction treatment series can be daunting. Patients have questioned the worth of these procedures when the expected benefit is modest and the time they devote to the project is significant. An eight-patient mini-study was performed to see if two or three "megasessions" could be substituted for eight weekly sessions of bipolar radiofrequency based fat reduction treatments. Patients were randomized into a two session or three session group by drawing straws. The device used was the BodyFX bipolar RF device by InMode. This device employs a suction coupled vacuum that heats a section of skin and soft tissue in the treatment region and delivers a high voltage pulse. Each patient was treated for 2 hours per session, using the Body FX, more superficial Mini FX, and the Deep FX device in an effort to treat on a multilevel basis. Preoperative 2D and 3D Vectra photos were taken, and were repeated at 1 month and 3 months post-treatment. Volumetric analysis and patient assessment showed similar results with a two or three treatment "megasession" protocol when compared with the traditional protocol of eight weekly sessions. While the cohort number was not statistically significant, the photographs and measurements are compelling enough to warrant further investigation into this treatment protocol.

2015-06-15

Purpose: This study is to evaluate the tumor regression over the course of EBRT treatment and to determine the difference of tumor reduction for stage III lung squamous cell cancer (SCC) and adenocarcinoma using CBCT. Methods: Twenty three stage III lung cancer patients treated in our clinic who had daily cone beam CT (CBCT) were selected for this study (16 adenocarcinoma and 7 SCC cases). Patients received prescription dose in the range of 50Gy–71.4Gy (mean =60.3Gy, median =50Gy) at 1.8Gy or 2Gy per fraction. Treatments spanned over a minimum of five weeks. Initial mean volume of the gross tumor volumemore » (GTV) was 123cc (range = 14.7cc–353.3cc). For this study, we choose six sets of CBCTs at an interval of one week, starting from the first fraction of treatment. Daily CBCTs from treatment linac computer were transferred to MIM Software version 6.0. An experienced physician contoured the primary GTV on each slices of the CBCT for these patients. Results: A consistent regression of the GTVs was observed in all patients, except in one patient (adeno case) where GTV did not change. Weekly volumetric reduction was in the range of 11.2%–16.6%. Maximum reductions were noticed in the first two weeks of the treatment cycle; mean overall (for adeno+SCC) reductions were 16.6%, 14.2% in week-1 and week-2, respectively. Mean reduction over five weeks of treatment was 49.8% (range = 0.1%–75.5%). Higher reduction was observed in SCC patients as compare to adenocarcinoma cases (54.9% vs. 47.6%); however, the difference was not statistically significant (p-value > 0.05). Conclusion: Large regression of tumors over the course of EBRT for stage III lung cancer patients was observed. Both SCC and adenocarcinoma responded well; overall reduction for SCC cases was higher. A future study is warranted for determining the co-relation between tumor volume reduction and treatment outcome.« less

Clinical and health care aspects of respiratory tract disorders in Poland.

Respiratory diseases constitute a public health priority worldwide. This is related to the increasing exposure to microorganisms, toxic factors, allergens, drugs and smoking, as the most important factors. Increasing costs of health promotion, prevention, diagnosis and treatment of respiratory tract diseases forces the search for effective strategies in the reduction of costs without making a significant impact of these activities on health results. Chronic obstructive pulmonary disease (COPD) is an example of these diseases with increasing incidence, which has few known modifiable factors and absorbs large medical and social costs. The aim of this study is to present the conception of cost driver analysis that could be useful in constructing a good combination of the EBM-based treatment with cost reduction decisions. Analysis of cost drivers was based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines and Polish recommendations of COPD diagnosis and treatment. The proposition of cost reduction strategy in COPD treatment was based on identification of cost drivers in value chain conception. An increasing incidence and treatment costs of COPD force the search for methods of costs reduction in health care. Identifying, evaluating and modifying the cost drivers with use of the value chain conception could be an effective method in achieving these objectives.

Forearm fractures are common in the paediatric age group. Closed reduction and casting are the primary means of treatment in over 90% of these fractures. Resultant deformities are usually a product of indirect trauma involving angular loading combined with rotational deformity and fragment displacement. Retrospectively, 48 patients aged between 4 to 12 years with forearm fractures, were treated conservatively with closed reduction and a cast during a 2-year period. Functional outcomes were measured in terms of pronation and supination. All fractures united before the final visit. Most forearm bone fractures were complete fractures at the mid shaft. Eighty-six percent of the patients had excellent functional outcomes and none had poor outcomes. There were significantly reduced angles of deformities before and after treatment (p < 0.05). Radiographically, in the frontal plane, 57.1% of radius and 73.9% of ulnar fractures achieved perfect reduction (i.e. a degree of deformity of less than 5 degrees). However, in the lateral plane, there were fewer perfect reductions for the radius and ulna, at 14.6% and 54.3%, respectively. All except for one patient were satisfied with the outcomes. The level of fracture did not influence the outcomes. Conservative treatment is still an acceptable form of treatment especially for stable forearm fractures in children achieving excellent outcomes (Tab. 1, Fig. 7, Ref. 20).

The aim of our study was to test the effect of a more viscous compound than existent hyaluronic acid formulation in helping to restore a defective glycosaminoglycan layer, and therefore in improving Interstitial Cystitis/Painful Bladder Syndrome (IC/PBS) symptoms when administered intravesically in IC/PBS patients. A total of 23 female patients completed the study. Patients received endovesical administration of hyaluronic acid and chondroitin sulfate in normal saline, 40 ml, weekly for 12 weeks and then bi-weekly for 6 months, if there was initial response. After 12 weeks treatment both Interstitial Cystitis Symptom and Problem Index (ICSI/ICPI), pelvic pain and Urgency/Frequency Symptom Scale (PUF) showed a mean significant improvement, which was maintained thereafter. The average number of voidings and mean voiding volumes revealed significant improvement after the 12 weeks' treatment period, with a significant reduction and increase, respectively. Mean voiding volume increased from 143 ml to 191, which apparently was not reflected in a corresponding reduction of number of daily voids (from 15,5 to 14). VAS values decreased from 5,4 to 3,6 (pain) and from 6,0 to 3,5 (urgency) after the treatment cycle, showing a significant improvement. In our preliminary experience, the administration of intravesical hyaluronic acid plus chondroitine sulphate appears to be a safe and efficacious method of treatment in IC/PBS.

The effectiveness and predictors of response to electroconvulsive therapy (ECT) combined with antipsychotics (AP) in treatment-resistant schizophrenia patients with the dominance of negative symptoms (TRS-NS) have not been studied systematically so far. 29 patients aged 21-55 years diagnosed with TRS-NS underwent ECT combined with antipsychotics (ECT+AP). Prior to the ECT, the symptom profile and severity were evaluated using Positive and Negative Syndrome Scale (PANSS). Demographic and medical data was collected; ECT parameters and pharmacotherapy results were evaluated. After the combined ECT+AP therapy a significant decrease in symptom severity was found. A response to treatment was achieved by 60% of patients. The greatest reductions were obtained in general and positive PANSS subscale (median change: 11 and 7 pts.) and the smallest, but still significant, ones in negative symptoms subscale (median: 3.5 pts.). Patients who responded to ECT+AP demonstrated a significantly shorter duration of the current episode in comparison with patients who did not experience at least a 25% reduction in symptom severity (median: 4 vs. 8 months). A combination of ECT and antipsychotic therapy can provide a useful treatment option for patients with TRS-NS. The only significant predictor of response to treatment was a shorter duration of the current episode. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Relations of mood with body mass index changes in severely obese women enrolled in a supported physical activity treatment.

2008-01-01

It has been suggested that physical activity may affect weight reduction outcomes through associated improvements in mood. Relations of physical activity, mood, and weight change are not well understood in persons classified as severely obese (BMI > or = 40 kg/m(2)), however. This research tested these relationships in women with severe obesity. 57 women with a mean BMI of 43.8 kg/m(2) were enrolled in a cognitive-behavioral exercise support treatment with group-based nutrition information. Measurement of depression, tension, overall mood, and BMI was taken at baseline and month 6, and exercise session attendance was recorded. The treatment was associated with significant improvements in depression, tension and total mood disturbance scores as well as in BMI over 6 months. Changes in mood scores that were more positive were correlated with a greater reduction in BMI. Mean attendance in the prescribed 3 session/week exercise regimen was 46.0%, and attendance was significantly correlated with changes in tension and total mood disturbance scores, and approached significance with changes in depression scores. Findings suggested significant relations of mood and weight change as well as of physical activity and mood in severely obese women associated with a treatment of moderate physical activity. With extensions of this research, weight loss theory and treatment may benefit. Copyright 2008 S. Karger AG, Basel.

This paper presents findings from a multi-centre, double-blind, randomized controlled trial that tested the hypothesis that parent and youth mental health improvements would be superior in a family-based intervention for adolescent depression (BEST MOOD) compared to a treatment-as-usual supportive parenting program (PAST). Eligible participants were families with a young person aged between 12 and 18 years who met diagnostic criteria for a depressive disorder (major, minor or dysthymic). Participating families (N = 64; 73.4% of youth were female) were recruited in Victoria, Australia and allocated to treatment condition using a block randomization procedure (parallel design) with two levels of blinding. This paper reports on the trial's secondary outcomes on youth and parent mental health. General linear mixed models were used to examine the longitudinal effect of treatment group on outcome. Data were analyzed according to intention-to-treat; 31 families were analyzed in BEST MOOD, and 33 families in PAST. Parents in the BEST MOOD group experienced significantly greater reductions in stress and depressive symptoms than parents in the PAST group at 3-month follow-up. A greater reduction in parental anxiety was observed in the BEST MOOD group (d = 0.35) compared with PAST (d = 0.02), although the between-group difference was not significant. Both groups of youth showed similar levels of improvement in depressive symptoms at post-treatment (d = 0.83 and 0.80 respectively), which were largely sustained at a 3-month follow-up. The family-based BEST MOOD intervention appeared superior to treatment-as-usual (PAST) in demonstrating greater reductions in parental stress and depression. Both interventions produced large reductions in youth depressive symptoms.

The little fire ant, Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae), is an invasive ant that forms supercolonies when it successfully invades new areas. W. auropunctata was first reported in Hawaii in 1999, and it has since invaded a variety of agricultural sites, including nurseries, orchards, and pastures. Amdro (hydramethylnon; in bait stations), Esteem (pyriproxyfen; broadcast bait), and Conserve (spinosad; ground spray) were tested for their efficacy against W. auropunctata in a rambutan, Nephelium lappaceum L. and mangosteen, Garcinia mangostana L., orchard by making treatments every 2 wk for 16 wk. Relative estimates of ant numbers in plots was determined by transect sampling using peanut butter-baited sticks. Significant treatment effects were observed on weeks 13-17, with reductions in ant counts occurring in the Amdro and Esteem treatments. During this period, the reduction in ant numbers from pretreatment counts averaged 47.1 and 92.5% in the Amdro and Esteem plots, respectively, whereas ant numbers in the untreated control plots increased by 185.9% compared with pretreatment counts. Conserve did not cause a reduction in ant counts as applied in our experiment. No plots for any of the treatments achieved 100% reduction. Pseudococcidae were counted on branch terminals at 4-wk intervals. The two predominant species, Nipaecoccus nipae (Maskell) and Nipaecoccus viridis (Newstead) were significantly lower in the Amdro and Esteem treatments on week 16 compared with controls. Many W. auropunctata were found nesting in protected sites in the orchard trees, which may have compromised the ground-based control methods. Absolute density estimates from shallow core samples taken from the orchard floor indicated the W. auropunctata supercolony exceeded 244 million ants and 22.7 kg wet weight per ha.

Filarial parasites can be targeted by antibiotic treatment due to their unique endosymbiotic relationship with Wolbachia bacteria. This finding has led to successful treatment strategies in both, human onchocerciasis and lymphatic filariasis. A 4–6 week treatment course using doxycycline results in long-term sterility and safe macrofilaricidal activity in humans. However, current treatment times and doxycycline contraindications in children and pregnant women preclude widespread administration of doxycycline in public health control programs; therefore, the search for shorter anti-wolbachial regimens is a focus of ongoing research. We have established an in vivo model for compound screening, using mice infected with Litomosoides sigmodontis. We could show that gold standard doxycycline treatment did not only deplete Wolbachia, it also resulted in a larval arrest. In this model, combinations of registered antibiotics were tested for their anti-wolbachial activity. Administration of rifamycins in combination with doxycycline for 7 days successfully depleted Wolbachia by > 2 log (>99% reduction) and thus resulted in a significant reduction of the treatment duration. Using a triple combination of a tetracycline (doxycycline or minocycline), a rifamycin and a fluoroquinolone (moxifloxacin) led to an even greater shortening of the treatment time. Testing all double combinations that could be derived from the triple combinations revealed that the combination of rifapentine (15mg/kg) and moxifloxacin (2 x 200mg/kg) showed the strongest reduction of treatment time in intraperitoneal and also oral administration routes. The rifapentine plus moxifloxacin combination was equivalent to the triple combination with additional doxycycline (>99% Wolbachia reduction). These investigations suggest that it is possible to shorten anti-wolbachial treatment times with combination treatments in order to achieve the target product profile (TPP) requirements for macrofilaricidal drugs of no more than 7–10 days of treatment.

We have established an in vivo model for compound screening, using mice infected with Litomosoides sigmodontis. We could show that gold standard doxycycline treatment did not only deplete Wolbachia, it also resulted in a larval arrest. In this model, combinations of registered antibiotics were tested for their anti-wolbachial activity. Administration of rifamycins in combination with doxycycline for 7 days successfully depleted Wolbachia by > 2 log (>99% reduction) and thus resulted in a significant reduction of the treatment duration. Using a triple combination of a tetracycline (doxycycline or minocycline), a rifamycin and a fluoroquinolone (moxifloxacin) led to an even greater shortening of the treatment time. Testing all double combinations that could be derived from the triple combinations revealed that the combination of rifapentine (15mg/kg) and moxifloxacin (2 x 200mg/kg) showed the strongest reduction of treatment time in intraperitoneal and also oral administration routes. The rifapentine plus moxifloxacin combination was equivalent to the triple combination with additional doxycycline (>99% Wolbachia reduction). These investigations suggest that it is possible to shorten anti-wolbachial treatment times with combination treatments in order to achieve the target product profile (TPP) requirements for macrofilaricidal drugs of no more than 7-10 days of treatment.

Behavior therapy is effective for Persistent Tic Disorders (PTDs), but behavioral processes facilitating tic reduction are not well understood. One process, habituation, is thought to create tic reduction through decreases in premonitory urge severity. The current study tested whether premonitory urges decreased in youth with PTDs (N = 126) and adults with PTDs (N = 122) who participated in parallel randomized clinical trials comparing behavior therapy to psychoeducation and supportive therapy (PST). Trends in premonitory urges, tic severity, and treatment outcome were analyzed according to the predictions of a habituation model, whereby urge severity would be expected to decrease in those who responded to behavior therapy. Although adults who responded to behavior therapy showed a significant trend of declining premonitory urge severity across treatment, results failed to demonstrate that behavior therapy specifically caused changes in premonitory urge severity. In addition, reductions in premonitory urge severity in those who responded to behavior therapy were significant greater than those who did not respond to behavior therapy but no different than those who responded or did not respond to PST. Children with PTDs failed to show any significant changes in premonitory urges. Reductions in premonitory urge severity did not mediate the relationship between treatment and outcome in either adults or children. These results cast doubt on the notion that habituation is the therapeutic process underlying the effectiveness of behavior therapy, which has immediate implications for the psychoeducation and therapeutic rationale presented in clinical practice. Moreover, there may be important developmental changes in premonitory urges in PTDs, and alternative models of therapeutic change warrant investigation. Copyright © 2017. Published by Elsevier Ltd.

The need for effective nonhormonal treatments for hot flash management without unwanted side effects continues. The primary aim of this pilot study was to evaluate the effect of combining a nonhormonal pharmacologic agent with a behavioral treatment for hot flash reduction. Seventy-one postmenopausal women were randomized to one of four groups: venlafaxine 75 mg + hypnosis (VH) versus venlafaxine 75 mg + sham hypnosis (VSH) versus a placebo pill + hypnosis (PH) versus placebo pill + sham hypnosis (PSH). Women recorded hot flash severity and frequency in a daily diary, in real time. The intrapatient difference in hot flash score (frequency × severity) at 8 weeks was analyzed using a General Estimating Equation model, using VSH as the referent arm, controlling for baseline hot flashes. The active arms including PH or VH were not statistically significantly different than VSH (P = 0.34, P = 0.05, respectively). Women in each active arm reported hot flash reductions of about 50%, with the PSH group reporting a 25% reduction. Women receiving the PSH reported statistically significantly smaller reductions in hot flash score than women in the referent VSH arm (P = 0.001). There were no significant negative side effects during the course of the study. Hypnosis alone reduced hot flashes equal to venlafaxine alone, but the combination of hypnosis and venlafaxine did not reduce hot flashes more than either treatment alone. More research is needed to clarify whether combining hypnosis with a different antidepressant would provide synergistic benefits.

Social anxiety disorder (SAD) is characterized by fears of social and performance situations. Cognitive behavioral group therapy (CBGT) has in general positive effects on symptoms, distress and avoidance in SAD. Prior studies found increased cortical volumes and decreased fractional anisotropy (FA) in SAD compared with healthy controls (HCs). Thirty-three participants diagnosed with SAD attended in a 10-week CBGT and were scanned before and after therapy. We applied three neuroimaging methods-surface-based morphometry, diffusion tensor imaging and network-based statistics-each with specific longitudinal processing protocols, to investigate CBGT-induced structural brain alterations of the gray and white matter (WM). Surface-based morphometry revealed a significant cortical volume reduction (pre- to post-treatment) in the left inferior parietal cortex, as well as a positive partial correlation between treatment success (indexed by reductions in Liebowitz Social Anxiety Scale) and reductions in cortical volume in bilateral dorsomedial prefrontal cortex. Diffusion tensor imaging analysis revealed a significant increase in FA in bilateral uncinate fasciculus and right inferior longitudinal fasciculus. Network-based statistics revealed a significant increase of structural connectivity in a frontolimbic network. No partial correlations with treatment success have been found in WM analyses. For, we believe, the first time, we present a distinctive pattern of longitudinal structural brain changes after CBGT measured with three established magnetic resonance imaging analyzing techniques. Our findings are in line with previous cross-sectional, unimodal SAD studies and extent them by highlighting anatomical brain alterations that point toward the level of HCs in parallel with a reduction in SAD symptomatology.

The current treatment and control of schistosomiasis, rely on a single drug, praziquantel, although, it has minor activity against juvenile stages of the parasite. Studies have shown that artemether (ART) exhibits effects against juveniles of Schistosoma mansoni Liberian and Puerto Rican strains, Schistosoma japonicum and Schistosoma haematobium. Aiming to assess the in vivo activity of single oral dose of ART against early juvenile stages of S. mansoni Egyptian strain, this study was established. Mice were treated with ART (400 mg/kg) at two time points evenly spaced over the period of larval development (7 and 21 days post-infection; pi), and a third treatment point (day 49 pi) was included to elucidate when susceptibility decreases. Administration of ART on day 7 pi reduced the total worm burden by 85.94%. The greatest reductions were seen when treatment was given on day 21 pi, with total and female worm burden reductions of 91.52% and 90.57%, respectively, and cessation of oviposition. Similar dose given on day 49 pi reduced total worm burden by 55.17% and female worm burden by 66.51%. Moreover, it induced significant reduction in the tissue egg load and significant alterations in the oogram pattern with decreased immature eggs and increased dead eggs. Antipathological activities were evident in significant reductions in granulomata count and diameter. In conclusion, ART exhibits major in vivo schistosomicidal effects against the early larval migratory stages of S. mansoni Egyptian strain, mainly the 21-day old schistosomula, hence preventing disease progression and morbidity.

Aspergillus flavus and Aspergillus parasiticus are primary pathogen moulds on brown rice and barley. This study investigated the effects of microwave irradiation (MWI) (2450 MHz, 700 W, 10-50 s) on inactivation of A. flavus and A. parasiticus on brown rice and barley and the quality of these samples. The counts of both strains were significantly (p < 0.05) reduced by the stepwise increase in MWI treatment time. The log reductions of A. flavus on brown rice and barley were 0.05 and 0.04 after 10 s; 1.06 and 1.05 after 20 s; 1.59 and 1.52 after 30 s; and 3.04 and 2.78 after 40 s. The log reductions of A. parasiticus on brown rice and barley were 0.06 and 0.10 after 10 s; 1.20 and 1.00 after 20 s; 2.04 and 1.61 after 30 s; and 2.89 and 2.90 after 40 s. Moreover, neither strain survived after 50 s of MWI. The Hunter colour 'L' gradually increased with increasing MWI treatment time. However, there were no significant differences in the 'L' of brown rice after 10-40 s of MWI treatment and of barley after 10-30 s of MWI treatment. The Hunter colour 'a' and 'b' gradually increased with increasing microwave time. No significant change was observed in the moisture content of either cereal treated with 10-20 s of MWI. The differences in the sensory quality (colour, appearance, flavour, texture and overall acceptability) after 0-30 s of MWI were not significant. However, values for colour, appearance, texture and overall acceptability were significantly reduced when treated with 40-50 s of MWI. Therefore, with 20 s of MWI at 2450 MHz, 700 W could be effective for > 90% reduction of mould without causing deleterious changes to the colour, moisture content and sensory qualities of these cereals.

Deficiencies in either growth hormone (GH) or insulin-like growth factor 1 (IGF-1) are associated with reductions in bone size during growth in humans and animal models. Liver-specific IGF-1-deficient (LID) mice, which have 75% reductions in serum IGF-1, were created previously to separate the effects of endocrine (serum) IGF-1 from autocrine/paracrine IGF-1. However, LID mice also have two- to threefold increases in GH, and this may contribute to the observed pubertal skeletal phenotype. To clarify the role of GH in skeletal development under conditions of significantly reduced serum IGF-1 levels (but normal tissue IGF-1 levels), we studied the skeletal response of male LID and control mice to GH inhibition by pegvisomant from 4 to 8 weeks of age. Treatment of LID mice with pegvisomant resulted in significant reductions in body weight, femur length (Le), and femur total area (Tt.Ar), as well as further reductions in serum IGF-1 levels by 8 weeks of age, compared with the mean values of vehicle-treated LID mice. Reductions in both Tt.Ar and Le were proportional after treatment with pegvisomant. On the other hand, the relative amount of cortical tissue formed (RCA) in LID mice treated with pegvisomant was significantly less than that in both vehicle-treated LID and control mice, indicating that antagonizing GH action, either directly (through GH receptor signaling inhibition) or indirectly (through further reductions in serum/tissue IGF-1 levels), results in disproportionate reductions in the amount of cortical bone formed. This resulted in bones with significantly reduced mechanical properties (femoral whole-bone stiffness and work to failure were markedly decreased), suggesting that compensatory increases of GH in states of IGF-1 deficiency (LID mice) act to protect against a severe inhibition of bone modeling during growth, which otherwise would result in bones that are too weak for normal and/or extreme loading conditions.

Objective To evaluate the efficacy and safety of USL255, Qudexy™ XR (topiramate) extended-release capsules, as an adjunctive treatment for refractory partial-onset seizures (POS) in adults taking one to three concomitant antiepileptic drugs. Methods In this global phase III study (PREVAIL; NCT01142193), 249 adults with POS were randomized 1:1 to once-daily USL255 (200 mg/day) or placebo. The primary and key secondary efficacy endpoints were median percent reduction in weekly POS frequency and responder rate (proportion of patients with ≥50% reduction in seizure frequency). Seizure freedom was also assessed. Safety (adverse events, clinical and laboratory findings), as well as treatment effects on quality of life (QOLIE-31-P) and clinical global impression of change (CGI-C), were evaluated. Results Across the entire 11-week treatment phase, USL255 significantly reduced the median percent seizure frequency and significantly improved responder rate compared with placebo. Efficacy over placebo was observed early in treatment, in patients with highly refractory POS, and in those with the most debilitating seizure types (i.e., complex partial, partial secondarily generalized). USL255 was safe and generally well tolerated with a low incidence of neurocognitive adverse events. USL255 was associated with significant clinical improvement without adversely affecting quality of life. Significance The PREVAIL phase III clinical study demonstrated that once-daily USL255 (200 mg/day) significantly improved seizure control and was safe and generally well tolerated with few neurocognitive side effects.

Abstract This study investigated clinical outcomes of biomimetic mineralized collagen artificial bone putty for bone reconstruction in the treatment of calcaneus fracture. Sixty cases of calcaneal fractures surgically treated with open reduction and internal fixation in our hospital from June 2014–2015 were chosen and randomly divided into two groups, including 30 cases treated with biomimetic mineralized collagen artificial bone putty as treatment group, and 30 cases treated with autogenous ilia as control group. The average follow-up time was 17.2 ± 3.0 months. The results showed that the surgery duration and postoperative drainage volume of treatment group were significantly lower than control group; there were no statistically significant differences in the fracture healing time, American Orthopaedic Foot and Ankle Society scores at 3 and 12 months after surgery, Böhler’s angle, Gissane’s angle and height of calcaneus between the two groups. There were no significant differences in wound complication and reject reaction between the two groups, while significant difference in donor site complication. As a conclusion, the implantation of biomimetic mineralized collagen artificial bone putty in the open reduction of calcaneal fracture resulted in reliable effect and less complications, which is suitable for clinical applications in the treatment of bone defect in calcaneal fractures.

Chronic low back pain (CLBP) is common and results in significant costs to individuals, families and society. Although some research supports the efficacy of hypnosis for CLBP, we know little about the minimum dose needed to produce meaningful benefits, the roles of home practice and hypnotizability on outcome, or the maintenance of treatment benefits beyond 3 months. One hundred veterans with CLBP participated in a randomized, four-group design study. The groups were (1) an eight-session self-hypnosis training intervention without audio recordings for home practice; (2) an eight-session self-hypnosis training intervention with recordings; (3) a two-session self-hypnosis training intervention with recordings and brief weekly reminder telephone calls; and (4) an eight-session active (biofeedback) control intervention. Participants in all four groups reported significant pre- to post-treatment improvements in pain intensity, pain interference and sleep quality. The hypnosis groups combined reported significantly more pain intensity reduction than the control group. There was no significant difference among the three hypnosis conditions. Over half of the participants who received hypnosis reported clinically meaningful (≥ 30%) reductions in pain intensity, and they maintained these benefits for at least 6 months after treatment. Neither hypnotizability nor amount of home practice was associated significantly with treatment outcome. The findings indicate that two sessions of self-hypnosis training with audio recordings for home practice may be as effective as eight sessions of hypnosis treatment. If replicated in other patient samples, the findings have important implications for the application of hypnosis treatment for chronic pain management. © 2014 European Pain Federation - EFIC®

Problematic anger is a significant clinical issue in military personnel, and is further complicated by comorbid post-traumatic stress disorder (PTSD). Despite increasing numbers of military personnel returning from deployment with anger and aggression difficulties, the treatment of problematic anger has received scant attention. There are currently no interventions that directly target problematic anger in the context of military-related PTSD. The aim of this case series is to examine the effectiveness of an intervention specifically developed for treating problematic anger in current serving military personnel with comorbid PTSD. Eight Australian Defence Force Army personnel with problematic anger and comorbid PTSD received a manualized 12-session cognitive behaviorally based anger intervention, delivered one-to-one by Australian Defence Force mental health clinicians. Standardized measures of anger, PTSD, depression, and anxiety were administered pre- and post-treatment. The initial mean severity scores for anger indicated a high degree of pre-treatment problematic anger. Anger scores reduced significantly from pre to post-treatment (d = 1.56), with 88% of participants exhibiting meaningful reduction in anger scores. PTSD symptoms also reduced significantly (d= 0.96), with 63% of participants experiencing a clinically meaningful reduction in PTSD scores. All of those who took part in the therapy completed all therapy sessions. This brief report provides preliminary evidence that an intervention for problematic anger not only significantly reduces anger levels in military personnel, but can also significantly reduce PTSD symptoms. Given that anger can interfere with PTSD treatment outcomes, prioritizing anger treatment may improve the effectiveness of PTSD interventions.

Objective This pilot study evaluates the pressure lowering potential of subthreshold micropulse diode laser trabeculoplasty (MDLT) for a clinically meaningful duration in patients with medically uncontrolled open angle glaucoma (OAG). Design prospective interventional case series. Participants Thirty-two eyes of 20 consecutive patients with uncontrolled OAG (12 bilateral and 8 unilateral). Methods Confluent subthreshold laser applications over the inferior 180° of the anterior TM using an 810 nm diode laser in a micropulse operating mode. The intraocular pressure (IOP) was measured at baseline and at 1 hour, 1 day, 1 week, 3, 6, 9, and 12 months post-treatment. Flare was measured with a Kowa FM 500 flare-meter at baseline and at 3 hours, 1 day, 1 week, and 12 months post-treatment. After treatment, the patients were maintained on their pre-treatment drug regimen. Main outcome measures Criteria for treatment response were IOP reduction ≥3 mm Hg and IOP ≤21 mm Hg within the first week after MDLT. Eyes not complying to the above criteria during the follow-up were considered treatment failure. Mean IOP change and percentage of IOP reduction during the follow-up were calculated. Results One eye was analyzed for bilateral patients. A total of 20 eyes were thus included. Four eyes (20%) did not respond to treatment during the first week. One additional eye failed at the 6 month visit. The treatment was successful in 15 eyes (75%) at 12 months. The IOP was significantly lower throughout follow-up (p < 0.01). At 12 months, the mean percentage of IOP reduction in the 15 respondent eyes was 22.1% and 12 eyes (60%) had IOP reduction higher than 20%. During the first two postoperative days, one eye with pigmentary glaucoma experienced a significant increase of flare associated with an IOP spike (34 mm Hg) that was controlled with systemic drugs; afterwards it qualified as a respondent and completed the study. No increase of flare was found in any other patient. No peripheral anterior synechiae formed. Conclusions In this case series, MDLT was effective in reducing IOP in 75% of medically insufficiently controlled OAG eyes without significant complications. This justifies randomized clinical studies to compare MDLT with current IOP lowering strategies. PMID:19668712

Gastrointestinal nematode (GIN) infections are the main impediments that restrict the welfare and productivity of small ruminant in the world. Effective management of GINs in grazing sheep relies heavily on the use of highly efficacious anthelmintic drugs. However, anthelmintic resistance is becoming a significant concern in the world, and this phenomenon severely threatens the potential utilisation of this control strategy. Therefore, this study was conducted 1) to evaluate the efficacy of commonly used anthelmintic on GINs in naturally infected sheep and 2) to assess the farmers' perception on anthelmintics utilisation practices in Dabat district, Northwest Ethiopia. One hundred twenty nematode infected sheep were used in this study. Sheep were selected based on the egg count (≥150 eggs per gram of faeces). The animals were allocated randomly into four groups (30 animals per group). Group-I, II and III were treated with Albendazole, Tetramisole, and Ivermectin, respectively. The 4th group was left untreated (as control). Faecal samples were collected on day 0 (before treatment), on day 3, 7, 10 and 14 (post-treatment). The modified McMaster technique was used for quantifying the eggs. Faecal egg count reduction test (FECRT) was applied to determine the efficacy of anthelmintic at day 14 (post-treatment). In addition, a questionnaire survey was conducted on 100 randomly selected sheep owners. All anthelmintics tested revealed significant ( P  < 0.05) reduction in nematode egg excretion in the sheep post-treatment. Faecal egg count reduction (FECR) levels for Albendazole, Tetramisole, and Ivermectin were 97.2, 98.9 and 97.7%, respectively. Post-treatment egg counts and percentage reduction of egg counts were not significantly different ( P  > 0.05) among the treatment groups. The nematode genera identified before treatment were Haemonchus , Trichostrongylus , Cooperia , Trichuris , Teladorsagia , Bunostomum, and Strongyloides. Haemonchus and Trichostrongylus were detected after treatment with Albendazole and Ivermectin. The questionnaire survey revealed that Albendazole was the most commonly (90%) used anthelmintic to treat nematodes in sheep, followed by Tetramisole (36%) and Tetraclozan (Tetramisole-Oxyclozanide combination) (20%). Respondents expressed that anthelmintic selection was made based on veterinarian prescription (84%), colour (27%), efficacy (4%), price affordability (1%) and availability (1%). This study demonstrated that the tested anthelmintics had an acceptable level of efficacy against GINs of sheep.

Fe(III) oxides accelerate microbial nitrate reduction and electricity generation by Klebsiella pneumoniae L17.

Klebsiella pneumoniae L17 is a fermentative bacterium that can reduce iron oxide and generate electricity under anoxic conditions, as previously reported. This study reveals that K. pneumoniae L17 is also capable of dissimilatory nitrate reduction, producing NO2(-), NH4(+), NO and N2O under anoxic conditions. The presence of Fe(III) oxides (i.e., α-FeOOH, γ-FeOOH, α-Fe2O3 and γ-Fe2O3) significantly accelerates the reduction of nitrate and generation of electricity by K. pneumoniae L17, which is similar to a previous report regarding another fermentative bacterium, Bacillus. No significant nitrate reduction was observed upon treatment with Fe(2+) or α-FeOOH+Fe(2+), but a slight facilitation of nitrate reduction and electricity generation was observed upon treatment with L17+Fe(2+). This result suggests that aqueous Fe(II) or mineral-adsorbed Fe(II) cannot reduce nitrate abiotically but that L17 can catalyze the reduction of nitrate and generation of electricity in the presence of Fe(II) (which might exist as cell surface-bound Fe(II)). To rule out the potential effect of Fe(II) produced by L17 during microbial iron reduction, treatments with the addition of TiO2 or Al2O3 instead of Fe(III) oxides also exhibited accelerated microbial nitrate reduction and electricity generation, indicating that cell-mineral sorption did account for the acceleration effect. However, the acceleration caused by Fe(III) oxides is only partially attributed to the cell surface-bound Fe(II) and cell-mineral sorption but may be driven by the iron oxide conduction band-mediated electron transfer from L17 to nitrate or an electrode, as proposed previously. The current study extends the diversity of bacteria of which nitrate reduction and electricity generation can be facilitated by the presence of iron oxides and confirms the positive role of Fe(III) oxides on microbial nitrate reduction and electricity generation by particular fermentative bacteria in anoxic environments.

Multi-objective optimisation of wastewater treatment plant control to reduce greenhouse gas emissions.

Sweetapple, Christine; Fu, Guangtao; Butler, David

2014-05-15

This study investigates the potential of control strategy optimisation for the reduction of operational greenhouse gas emissions from wastewater treatment in a cost-effective manner, and demonstrates that significant improvements can be realised. A multi-objective evolutionary algorithm, NSGA-II, is used to derive sets of Pareto optimal operational and control parameter values for an activated sludge wastewater treatment plant, with objectives including minimisation of greenhouse gas emissions, operational costs and effluent pollutant concentrations, subject to legislative compliance. Different problem formulations are explored, to identify the most effective approach to emissions reduction, and the sets of optimal solutions enable identification of trade-offs between conflicting objectives. It is found that multi-objective optimisation can facilitate a significant reduction in greenhouse gas emissions without the need for plant redesign or modification of the control strategy layout, but there are trade-offs to consider: most importantly, if operational costs are not to be increased, reduction of greenhouse gas emissions is likely to incur an increase in effluent ammonia and total nitrogen concentrations. Design of control strategies for a high effluent quality and low costs alone is likely to result in an inadvertent increase in greenhouse gas emissions, so it is of key importance that effects on emissions are considered in control strategy development and optimisation.

Group-based exposure therapy (GBET) of 16-week duration was developed to treat combat-related posttraumatic stress disorder (PTSD) and decreased PTSD symptoms in 3 noncontrolled open trials with low attrition (0%-5%). Group-based exposure therapy has not produced as much PTSD symptom reduction as Prolonged Exposure (PE) within a U.S. Veterans Affairs PTSD treatment program, although PE had more dropouts (20%). This pilot study was of a model that combined key elements of GBET with components of PE in an effort to increase the effectiveness of a group-based treatment while reducing its length and maintaining low attrition. Twice per week, 8 Vietnam combat veterans with PTSD were treated for 12 weeks, with an intervention that included 2 within-group war trauma presentations per participant, 6 PE style individual imaginal exposure (IE) sessions per participant, daily listening to recorded IE sessions, and daily in vivo exposure exercises. All completed treatment and showed Significant reductions on all measures of PTSD with large effect sizes; 7 participants no longer met PTSD criteria on treating clinician administered interviews and a self-report measure at posttreatment. Significant reductions in depression with large effect sizes and moderate reductions in PTSD-related cognitions were also found. Most gains were maintained 6 months posttreatment. Published 2012.

Waljee, Jennifer F.; Zhong, Lin; Shauver, Melissa

2014-01-01

Background: Distal radius fractures (DRFs) are one of the most common injuries among the elderly, resulting in significant expense and disability. The specific aims of this study are (1) to examine rates of therapy following DRFs and (2) to identify those factors that influence utilization of therapy and time span between DRF treatment and therapy among a national cohort of elderly patients. Methods: We examined national use of physical and occupational therapy among all Medicare beneficiaries who suffered DRFs between January 1, 2007, and October 1, 2007, and assessed the effect of treatment, patient-related, and surgeon-related factors on utilization of therapy. Results: Overall, 20.6% of patients received either physical or occupational therapy following DRF. Use of therapy varied by DRF treatment, and patients who underwent open reduction and internal fixation were more likely to receive therapy compared with patients who received closed reduction. Patients who received open reduction and internal fixation were also referred to therapy earlier compared with patients who received external fixation, percutaneous pinning, and closed reduction. Surgeon specialization is associated with greater use of postoperative therapy. Patient predictors of therapy use include younger age, female sex, higher socioeconomic status, and fewer comorbidity conditions. Conclusion: Use of therapy following DRF varies significantly by both patient- and surgeon-related factors. Identifying patients who benefit from postinjury therapy can allow for better resource utilization following these common injuries. PMID:25289323

Ivacaftor produces significant clinical benefit in patients with cystic fibrosis (CF) with the G551D mutation. Prevalence of this mutation at the Cork CF Centre is 23%. This study assessed the impact of cystic fibrosis transmembrane conductance regulator modulation on multiple modalities of patient assessment. Thirty-three patients with the G551D mutation were assessed at baseline and prospectively every 3 months for 1 year after initiation of ivacaftor. Change in ultra-low-dose chest CT scans, blood inflammatory mediators, and the sputum microbiome were assessed. Significant improvements in FEV 1 , BMI, and sweat chloride levels were observed post-ivacaftor treatment. Improvement in ultra-low-dose CT imaging scores were observed after treatment, with significant mean reductions in total Bhalla score (P < .01), peribronchial thickening (P = .035), and extent of mucous plugging (P < .001). Reductions in circulating inflammatory markers, including interleukin (IL)-1β, IL-6, and IL-8 were demonstrated. There was a 30% reduction in the relative abundance of Pseudomonas species and an increase in the relative abundance of bacteria associated with more stable community structures. Posttreatment community richness increased significantly (P = .03). Early and sustained improvements on ultra-low-dose CT scores suggest it may be a useful method of evaluating treatment response. It paralleled improvement in symptoms, circulating inflammatory markers, and changes in the lung microbiota. Copyright © 2017 American College of Chest Physicians. Published by Elsevier Inc.

The objective of the present studies was to evaluate the efficacy of a combined formulation (Startect(®) Dual Active Oral Solution for Sheep, Pfizer Animal Health) of derquantel (DQL) and abamectin (ABA) for the treatment of: (1) sheep experimentally infected with a moxidectin (MOX)-resistant isolate of Teladorsagia circumcincta, and (2) multi-drug resistant gastrointestinal nematode parasites under UK field conditions. In the first study, a total of 40 animals were allocated into 4 treatment groups, and were either left untreated or treated with DQL+ABA, MOX or ABA. Faecal samples were collected on days 1-5 and on day 7 after treatment to examine the reduction in faecal egg excretion and to evaluate the egg viability. On day 14 post treatment all animals were euthanised for abomasal worm counts. There was a 100% reduction in geometric mean worm counts for the DQL+ABA treated animals compared to the untreated control animals (P<0.0001), whereas the percentage reduction in worm counts for the MOX- (P>0.05) and ABA-treated (P=0.0004) animals was 12.4% and 71.8%, respectively. The data from the egg hatch assay (EHA) indicated that in the MOX-treated and the ABA-treated animals, the majority of the eggs hatched after treatment. In the field study, performed on four farms, animals were allocated into 6 groups of 11-15 animals each in order to conduct a faecal egg count reduction test (FECRT), based on arithmetic mean egg counts. One group of animals remained untreated, whereas the other animals were treated with DQL+ABA, MOX, fenbendazole (FBZ), levamisole (LV) or ivermectin (IVM). On each of the farms the reduction in egg excretion after treatment with FBZ, LV or IVM was below 95.0%, indicating anthelmintic resistance. The efficacy of DQL+ABA ranged from 99.1 to 100%, yielding significantly lower egg counts compared to the untreated control group (P ≤ 0.003). For MOX the egg counts were significantly (P ≤ 0.003) lower compared to the untreated group at each farm, with reductions varying from 98.2 to 100%. The post-treatment copro-cultures for larva identification indicated that T. circumcincta was the most abundant worm species after treatment (52-99% of the larvae). The results of these studies confirm the high efficacy of the DQL+ABA combination formulation against anthelmintic resistant nematodes in the UK. Copyright © 2012 Elsevier B.V. All rights reserved.

One of the most serious problems in tuberculosis (TB) control is non-adherence to treatment. Several strategies have been developed to improve adherence and increase the cure rate. To systematically review interventions to improve adherence to anti-tuberculosis treatment. We performed a systematic review and meta-analysis of 22 randomised clinical trials (RCTs) to ascertain whether providing directly observed treatment, short-course (DOTS), financial incentives, food incentives and/or patient education/counselling improved adherence to anti-tuberculosis treatment. The primary outcome was cure rate; secondary outcomes were default and mortality rates. Sources used were Medline (accessed via PubMed), Cochrane Central, LILACS (Literatura Latino Americana em Ciências da Saúde, Latin American and Caribbean Health Sciences Literature) and Embase from inception to October 2015. A significant increase in cure rates, by 18% with DOTS and by 16% with patient education and counselling, was observed. In addition, the default rate decreased by 49% with DOTS, by 26% with financial incentives and by 13% with patient education and counselling. There was no statistically significant reduction in mortality rates with these interventions. Use of DOTS and patient education/counselling significantly improved cure rates; DOTS, patient education/counselling and financial incentives led to a reduction in the default rate.

To compare the efficacy of a developmentally appropriate cognitive-behavioral therapy protocol for preschoolers with severe nighttime fears and sleep-related problems, with an active control treatment. Ninety children aged four to six years (63% boys) with severe nighttime fears and their parents were randomized to either cognitive-behavioral therapy including parent involved play (CBT-PIP) or to a structurally equivalent non-directive treatment (TEPT; triadic expressive play therapy). Treatment conditions were also equivalent in parent- and child-rated credibility and expectancy, and in therapist-rated compliance. Children and parents were assessed at baseline, during the first intervention week and four weeks after treatment. Measures included actigraphy, daily sleep logs, structured diagnostic interviews and parent questionnaires. Significant reductions were observed in nighttime fears and objectively and subjectively measured sleep disruptions in both intervention groups following treatment. Parent reports indicated more advantageous outcomes for CBT-PIP compared to TEPT, with greater reductions in sleep problems and co-sleeping as well as higher customer satisfaction in the former group. While CBT-PIP showed no significant advantage compared to the active control in reducing fears or in improving objectively measured sleep, it was significantly more beneficial in reducing the adverse behavioral features of nighttime fears.

To compare different therapeutic supportive approaches in patients with burning mouth syndrome. A prospective study was carried out for this purpose. The study involved 56 patients with burning mouth syndrome. They were randomly assigned to treatment with capsaicin, alpha-lipoic acid or lysozyme-lactoperoxidase (test drugs) or boric acid (control group). Symptoms were scored after 60 days treatment and 60 days after drug discontinuation. At the end of the treatment period, there was a significant reduction in the symptom scores of all of the patients who received the test drugs (P<0.01), and at the end of the follow-up period in the test groups as a whole (P<0.01); the reduction was not significant when considering each test group separately after the treatment period. All of the treatments were more effective than boric acid and there was no significant difference in the symptom scores of the control group at either of the study time-points. Our results demonstrate the similar effectiveness of capsaicin and alpha-lipoic acid in controlling the symptoms of burning mouth syndrome. Lysozyme-lactoperoxidase may be effective in the supportive care of BMS patients with xerostomia. The transitory effect observed after discontinuing drug administration justifies the use of prolonged therapy in chronically affected patients. © 2010 John Wiley & Sons A/S.

The present study investigates the effect of Sahaja yoga meditation on quality of life, anxiety, and blood pressure control. The prospective observational cohort study enrolled two study groups: those receiving treatment from the International Sahaja Yoga Research and Health Center (meditation group) and those receiving treatment from the Mahatma Gandhi Mission Hospital (control group). Researchers measured quality of life, anxiety, and blood pressure before and after treatment. Sixty-seven (67) participants in the meditation group and 62 participants in the control group completed the study. The two groups were comparable in demographic and clinical characteristics. At baseline, the meditation group had higher quality of life (p<0.001) than controls but similar anxiety level (p=0.74) to controls. Within-group pre- versus post-treatment comparisons showed significant improvement in quality of life, anxiety, and blood pressure in the meditation group (p<0.001), while in controls, quality of life deteriorated and there was no improvement in blood pressure. The improvement in quality of life, anxiety reduction, and blood pressure control was greater in the meditation group. The beneficial effect of meditation remained significant after adjusting for confounders. Meditation treatment was associated with significant improvements in quality of life, anxiety reduction, and blood pressure control.

The clinical efficacy of a recombinant feline interferon (IFN) (type omega) was evaluated under field conditions for the treatment of dogs with parvoviral enteritis. In this multicentric, double-blind, placebo-controlled trial, 94 dogs from one to 28 months old were randomly assigned to two groups which were treated intravenously either with IFN (2.5 million units/kg) or placebo once a day for three consecutive days, and monitored for clinical signs and mortality for 10 days. Each dog received individual supportive treatment The data from 92 interpretable cases (43 IFN-treated and 49 placebo) showed that the clinical signs of the IFN-treated animals improved significantly in comparison with the control animals, and that there were only three deaths in the IFN group compared with 14 deaths in the placebo group (P = 0.0096) corresponding to a 4.4-fold reduction. Alternative analyses of the data taking into account the prior vaccination status of the dogs against canine parvovirus suggested that the IFN therapy resulted in a 6.4-fold reduction in mortality (P = 0.044) in the unvaccinated cohort, a significant reduction when compared with the vaccinated cohort.

2018-01-01

Background: Specialized inpatient or residential treatment might be an alternative treatment approach for patients with obsessive-compulsive disorder (OCD) that do not respond satisfactorily to the standard outpatient treatment formats. Method: The aim of this open trial was to investigate the 6-month effectiveness of a 3-week inpatient treatment of OCD, where exposure with response prevention (ERP) was the main treatment intervention. The sample consisted of 187 adult patients with OCD, all with previous treatment attempts for OCD. Results: The sample showed significant reductions in symptoms of OCD and depression. The effect sizes were large for obsessive-compulsive symptoms and moderate to large for depressive symptoms. At discharge, 79.7% of the intent-to-treat (ITT) group were classified as treatment responders (≥35% reduction in Y-BOCS scores). However, some participants experienced relapse, as 61.5% of the ITT group were classified as treatment responders at 6-month follow-up. Antidepressant use appeared not to influence the outcome. Only pre-treatment levels of obsessive-compulsive symptoms emerged as a significant predictor of relapse. Conclusion: The 3-week inpatient programme produced similar treatment effects as previous inpatient and residential studies of longer duration (2 - 3 months). The results suggest that patients with severe OCD can be treated efficiently using this brief inpatient format. However, better relapse prevention interventions are needed.

This article studies a contemporary treatment approach toward both diabetes and depression management by vanadium-enriched Cordyceps sinensis (VECS). Streptozotocin-induced hyperglycemic rats were used in the study. After the rats were administered with VECS, a significant reduction in blood glucose levels was seen (P < .05) and the levels of serum insulin increased significantly (P < .05). At the same time, the study revealed a significant decrease in immobility with a corresponding increase in the swimming and climbing behavior in hyperglycemic rats following VECS treatment. The results described herein demonstrate that VECS is a contemporary treatment approach that advocates an aggressive stance toward both diabetes and depression management. PMID:21799679

Prolonged air leak is reported in up to 50% of patients after lung volume reduction surgery. The effect of an autologous fibrin sealant on the intensity and duration of air leak and on the time to chest drain removal after lung volume reduction surgery was investigated in a randomized prospective clinical trial. Twenty-five patients underwent bilateral thoracoscopic lung volume reduction surgery. In each patient, an autologous fibrin sealant was applied along the staple lines on one side, whereas no additional measure was taken on the other side. Randomization of treatment was performed at the end of the resection on the first side. Air leak was assessed semiquantitatively by use of a severity score (0 = no leak; 4 = continuous severe leak) by two investigators blinded to the treatment. Mean value of the total severity scores for the first 48 hours postoperative was significantly lower in the treated group (4.7 +/- 7.7) than in the control group (16.0 +/- 10.1) (P < .001), independently of the length of the resection. Prolonged air leak and mean duration of drainage were also significantly reduced after application of the sealant (4.5% and 2.8 +/- 1.9 days versus 31.8% and 5.9 +/- 2.9 days) (P = .03 and P < .001). Autologous fibrin sealant for reinforcement of the staple lines after lung volume reduction surgery significantly reduces prolonged air leak and duration of chest tube drainage.

We studied 13 U.S. male military veterans and their female partners who consented to participate in an uncontrolled trial of couple treatment for alcohol use disorder and posttraumatic stress disorder (CTAP). CTAP is a 15-session, manualized therapy, integrating behavioral couples therapy for alcohol use disorder (AUD) with cognitive-behavioral conjoint therapy for posttraumatic stress disorder (PTSD). Due to ineligibility (n = 1) and attrition (n = 3), 9 couples completed the study, and 7 completed 12 or more sessions. There were 8 veterans who showed clinically reliable pre- to posttreatment reduction of PTSD outcomes. There were also significant group-level reductions in clinician-, veteran-, and partner-rated PTSD symptoms (d = 0.94 to 1.71). Most veterans showed clinically reliable reductions in percentage days of heavy drinking. Group-level reduction in veterans' percentage days of heavy drinking was significant (d = 1.01). There were 4 veterans and 3 partners with clinically reliable reductions in depression, and group-level change was significant for veterans (d = 0.93) and partners (d = 1.06). On relationship satisfaction, 3 veterans and 4 partners had reliable improvements, and 2 veterans and 1 partner had reliable deterioration. Group-level findings were nonsignificant for veteran relationship satisfaction (d = 0.26) and for partners (d = 0.52). These findings indicate that CTAP may be a promising intervention for individuals with comorbid PTSD and AUD who have relationship partners.

We explored whether transdiagnostic internet-delivered cognitive behavioural therapy (iCBT) for mixed anxiety and depression effectively reduces repetitive negative thinking (RNT), and whether reductions in RNT and positive metacognitive beliefs mediate symptom improvement during iCBT. Participants with generalized anxiety disorder (GAD), major depressive disorder (MDD), or mixed GAD/MDD diagnoses were randomly allocated to a 6-lesson clinician-guided iCBT anxiety and depression program (n = 46) or wait-list control (WLC, n = 53). Depression (PHQ-9), generalized anxiety (GAD-7), RNT (Repetitive Thinking Questionnaire) and positive beliefs about RNT (Positive Beliefs about Rumination Scale) were assessed at pre-, mid-, and post-treatment or matched time points for WLC. Tests of serial indirect effects explored the potential meditating role of RNT and positive belief reductions on the impact of iCBT on depression and anxiety symptoms post-treatment. Results showed that both RNT frequency and positive beliefs about the value of RNT reduced significantly following iCBT compared to WLC, with gains maintained at 3-month follow-up. Reductions between pre- and mid-treatment in positive beliefs and RNT mediated improvements in depression symptoms post-iCBT, and reductions in positive beliefs mediated improvements in GAD symptoms. These findings indicate that iCBT is an effective treatment for RNT and positive metacognitive beliefs. Future dismantling studies are needed to assess the most effective treatment components.

2017-01-01

Endoscopic lung volume reduction coil (LVRC) treatment is an option for selected patients with severe emphysema. In the advanced stages, emphysema leads to respiratory failure: hypoxemia and eventually chronic hypercapnic respiratory failure. It can be hypothesized that LVRC treatment, a procedure targeting hyperinflation and thereby reducing ventilatory workload, may be especially beneficial in patients with chronic hypercapnic respiratory failure. This study was conducted to gain first insights into the effects and the safety of LVRC treatment in patients with emphysema and chronic hypercapnic respiratory failure. A retrospective observational study conducted in the Department of Respiratory Medicine at the University Medical Center Hamburg-Eppendorf, Germany on all patients with chronic hypercapnic respiratory failure in whom bilateral LVRC treatment was performed between 1 April 2012 and 30 September 2015. During the study period, bilateral LVRC treatment was performed in 10 patients with chronic hypercapnic respiratory failure. Compared with baseline, bilateral LVRC treatment led to a significant increase in mean forced expiratory volume in one second (FEV 1 ) from 0.5 ± 0.1 l to 0.6 ± 0.2 l ( p = 0.004), a decrease in residual volume (RV) from 6.1 ± 0.9 l to 5.6 ± 1.1 l ( p = 0.02) and a reduction in partial pressure of carbon dioxide in arterial blood (PaCO 2 ) from 53 ± 5 mmHg to 48 ± 4 mmHg ( p = 0.03). One case of hemoptysis requiring readmission to hospital was the only severe adverse event. LVRC treatment was safe and effective in patients with nonsevere chronic hypercapnic respiratory failure. It led not only to an improvement in lung function but also to a significant decrease in PaCO 2 .

It is unclear whether N-acetylaspartate (NAA) depletions documented in schizophrenia patients might be due to the disease progression or medications. Here we investigated longitudinal NAA changes in drug-naïve first-episode patients (FEP) who are relatively free from chronicity. Forty-two drug-naïve FEP and 38 controls were enrolled in this study to explore the effect of 8-week risperidone monotherapy on NAA. All spectra were obtained from the medial prefrontal cortex (MPFC) on a 3.0 T MRI and analyzed with LCModel. At baseline, patients presented no significant differences in NAA (P = 0.084) or NAA/Cr + Pcr (P = 0.500) compared to controls; NAA levels were negatively correlated with PANSS total scores (P = 0.001) and WCST-PE (P = 0.041). After treatment, patients demonstrated significant reductions of NAA (P < 0.001) and NAA/Cr + Pcr (P < 0.001), and significant improvement in PANSS-P (P < 0.001) and PANSS-G (P < 0.001) symptoms. We detected no significant correlations between NAA alterations and PANSS-P (P = 0.679) or PANSS-G (P = 0.668) symptom changes; nor did NAA/Cr + Pcr changes with alterations in PANSS-P (P = 0.677) and PANSS-G (P = 0.616). This is the first evidence that short-term risperidone treatment induces an acute reduction of MPFC NAA during the early phase of schizophrenia, which may be a previously unavailable biomarker to indicate risperidone with a similar pharmacological mechanism, although the functional significance is still unclear.

Two-thirds of adults worldwide will experience low back pain at some point in their life. In the following case series, we present four patients with sacroiliac (SI) joint instability and severe chronic low back pain, which was refractory to other treatment modalities. We investigated the efficacy of platelet-rich plasma (PRP) injections, a novel orthobiologic therapy, for reducing SI joint pain, improving quality of life, and maintaining a clinical effect. Short-form McGill Pain Questionnaire (SFM), Numeric Rating Scale (NRS), and Oswestry Low Back Pain and Disability Index were used for evaluation of treatment at pretreatment, 12-months and 48-months after treatment. At follow-up 12-months post-treatment, pooled data from all patients reported a marked improvement in joint stability, a statistically significant reduction in pain, and improvement in quality of life. The clinical benefits of PRP were still significant at 4-years post-treatment. Platelet-rich plasma therapy exhibits clinical usefulness in both pain reduction and for functional improvement in patients with chronic SI joint pain. The improvement in joint stability and low back pain was maintained at 1- and 4-years post-treatment.

The purpose of this study was to examine whether treatment response to fluoxetine by depressed outpatients was predicted by early improvement on any of 3 subscales (Anxiety, Depression, and Anger/Hostility) of the Symptom Questionnaire (SQ). We evaluated 169 depressed outpatients (52.6% female) between ages 18 and 65 (mean age, 40.3 +/- 10.6 years) meeting DSM-IIIR criteria for major depressive disorder (MDD). All patients completed the SQ at baseline (week 0) and at weeks 2, 4, and 8 of treatment with fluoxetine 20 mg/d. We defined treatment response as a > or= 50% reduction in score on the 17-item Hamilton Rating Scale for Depression, and early improvement on 3 SQ subscales (Anxiety, Depression, and Anger/Hostility) as a >30% reduction in score by week 2. The percentage of patients with significant early improvement in anger was significantly greater than the percentage of those with early improvements in anxiety or depression. When early improvement on the Anxiety, Depression, and Anger/Hostility subscales of the SQ were assessed independently by logistic regression, all 3 subscales were predictors of response to treatment. Early improvement in anger, anxiety, and depressive symptoms may predict response to antidepressant treatment among outpatients with MDD.

Multi-walled Carbon Nanotubes Reduce Toxicity of Diphenhydramine to Ceriodaphnia dubia in Water and Sediment Exposures.

Multi-walled carbon nanotubes are adsorptive materials that have potential for remediation of organic contaminants in water. Sediment elutriate exposures were undertaken with Ceriodaphnia dubia to compare the toxic effects of diphenhydramine in the presence and absence of sediment and multi-walled carbon nanotubes. In both sediment and solution-only treatments, addition of 0.318 mg/g of carbon nanotubes significantly decreased 48-h mortality relative to control, with a 78.7%-90.1% reduction in treatments with nanotube-amended sediment and 40.7%-53.3% reduction in nanotube-amended water exposures. The greatest degree of relative mortality reduction occurred in sediments containing higher levels of natural organic matter, indicating a potential additive effect.

Greenhouse gas reductions through enhanced use of residues in the life cycle of Malaysian palm oil derived biodiesel.

Hansen, Sune Balle; Olsen, Stig Irving; Ujang, Zaini

2012-01-01

This study identifies the potential greenhouse gas (GHG) reductions, which can be achieved by optimizing the use of residues in the life cycle of palm oil derived biodiesel. This is done through compilation of data on existing and prospective treatment technologies as well as practical experiments on methane potentials from empty fruit bunches. Methane capture from the anaerobic digestion of palm oil mill effluent was found to result in the highest GHG reductions. Among the solid residues, energy extraction from shells was found to constitute the biggest GHG savings per ton of residue, whereas energy extraction from empty fruit bunches was found to be the most significant in the biodiesel production life cycle. All the studied waste treatment technologies performed significantly better than the conventional practices and with dedicated efforts of optimized use in the palm oil industry, the production of palm oil derived biodiesel can be almost carbon neutral.

Wendt, Christopher; Ives, Rebecca; Hoyt, Anne L.; Conrad, Ken E.; Longstaff, Stephanie; Kuennen, Roy W.; Rose, Joan B.

2015-01-01

Two point-of-use drinking water treatment systems designed using a carbon filter and foam material as a possible alternative to traditional biosand systems were evaluated for removal of bacteria, protozoa, and viruses. Two configurations were tested: the foam material was positioned vertically around the carbon filter in the sleeve unit or horizontally in the disk unit. The filtration systems were challenged with Cryptosporidium parvum, Raoultella terrigena, and bacteriophages P22 and MS2 before and after biofilm development to determine average log reduction (ALR) for each organism and the role of the biofilm. There was no significant difference in performance between the two designs, and both designs showed significant levels of removal (at least 4 log10 reduction in viruses, 6 log10 for protozoa, and 8 log10 for bacteria). Removal levels meet or exceeded Environmental Protection Agency (EPA) standards for microbial purifiers. Exploratory test results suggested that mature biofilm formation contributed 1–2 log10 reductions. Future work is recommended to determine field viability. PMID:25758649

Computational Study of Porous Treatment for Altering Flap Side-Edge Flowfield

NASA Technical Reports Server (NTRS)

Choudhari, Meelan; Khorrami, Mehdi R.

2003-01-01

Reynolds-averaged Navier-Stokes calculations are used to investigate porous side-edge treatment as a passive means for flap noise reduction. Steady-state simulations are used to infer effects of the treatment on acoustically relevant features of the mean flow near the flap side edge. Application of the porous treatment over a miniscule fraction of the wetted flap area (scaling with the flap thickness) results in significantly weaker side-edge vortex structures via modification of the vortex initiation and roll-up processes. At high flap deflections, the region of axial flow reversal associated with the breakdown of the side-edge vortex is also eliminated, indicating an absence of vortex bursting in the presence of the treatment. Potential ramifications of the mean-flow modifications for flap-noise reduction are examined in the light of lessons learned from recent studies on flap noise. Computations confirm that any noise reduction benefit via the porous treatment would be achieved without compromising the aerodynamic effectiveness of the flap. Results of the parameter study contribute additional insight into the measured data from the 7x10 wind tunnel at NASA Ames and provide preliminary guidance for specifying optimal treatment characteristics in terms of treatment location, spatial extent, and flow resistance of the porous skin.

2006-12-20

The need of a combination of animal treatment and environmental measures against a natural Giardia infection in calves between the age of 1 and 6 months was emphasized and evaluated. Ten commercial farms with a total of 94 calves suffering from chronic diarrhea, ill thriving and impaired growth, were included in two subsequent studies. The first study indicated that treatment of all animals with fenbendazole at 15 mg/kg during 3 consecutive days combined with environmental measures on the final day of treatment, which were either removal of bedding, thorough cleaning and ammonia 10% disinfection or relocation of the treated animals to a Giardia free environment, resulted in a total reduction in cyst excretion for at least 2 weeks. In the second study, the immunofluorescence assay (Merifluor Cryptosporidium/Giardia; Meridian Diagnostics Inc., Cincinnati, Ohio) was used quantitatively and confirmed that the combination of treatment and environmental measures resulted in a total reduction of cyst excretion during 2 weeks and in a significant (P<0.05; >or=98.0%) reduction of the cyst excretion until at least 4 weeks after treatment. Furthermore, there was a noticeable improvement of the clinical symptoms in all animals towards day 28 after treatment and 4 months after treatment health in all calves was normal.

Attention-deficit/hyperactivity disorder (ADHD) has been found to be highly comorbid in children and adolescents with obsessive-compulsive disorder (OCD). Some have proposed, however, that obsessive anxiety may cause inattention and executive dysfunction, leading to inappropriate ADHD diagnoses in those with OCD. If this were the case, these symptoms would be expected to decrease following successful OCD treatment. The present study tested this hypothesis and evaluated whether ADHD symptoms at baseline predicted OCD treatment response. Obsessive-compulsive and ADHD symptoms were assessed in 50 youth enrolled in a randomized controlled trial investigating selective serotonin reuptake inhibitor and cognitive behavioral treatment. Repeated-measures analysis of variance (RMANOVA) revealed that ADHD symptoms at baseline do not significantly predict treatment outcome. A multivariate RMANOVA found that OCD treatment response moderated change in inattention; participants who showed greater reduction in OCD severity experienced greater reduction in ADHD-inattentive symptoms, while those with less substantial reduction in obsessions and compulsions showed less change. These findings suggest that children and adolescents with OCD and inattention may experience meaningful improvements in attention problems following OCD treatment. Thus, in many youth with OCD, inattention may be inherently tied to obsessions and compulsions. Clinicians may consider addressing OCD in treatment before targeting inattentive-type ADHD.

Sleep disturbance is prevalent in anxious youth and prospectively predicts poor emotional adjustment in adolescence. Study 1 examined whether anxiety treatment improves subjective and objective sleep disturbance in anxious youth. Study 2 examined whether a sleep intervention called Sleeping TIGERS can further improve sleep following anxiety treatment. Study 1 examined 133 youth (ages 9-14; 56% female; 11% ethnic/racial minority) with generalized, social, or separation anxiety over the course of anxiety treatment (cognitive behavioral treatment or client-centered treatment). Sleep-related problems (parent-, child-report) and subjective (diary) and objective (actigraphy) sleep patterns were assessed across treatment in an open trial design. Study 2 included 50 youth (ages 9-14; 68% female; 10% ethnic/racial minority) who continued to report sleep-related problems after anxiety treatment and enrolled in an open trial of Sleeping TIGERS. Pre- and postassessments duplicated Study 1 and included the Focal Interview of Sleep to assess sleep disturbance. Study 1 demonstrated small reductions in sleep problems and improvements in subjective sleep patterns (diary) across anxiety treatment, but outcomes were not deemed clinically significant, and 75% of youth stayed above clinical cutoff. Study 2 showed clinically significant, large reductions in sleep problems and small changes in some subjective sleep patterns (diary). Anxiety treatment improves, but does not resolve, sleep disturbance in peri-pubertal youth, which may portend risk for poor emotional adjustment and mental health. The open trial provides preliminary support that Sleeping TIGERS can improve sleep in anxious youth to a clinically significant degree.

To investigate if the effectiveness of a 96-hour multidisciplinary headache treatment program exceeds the effectiveness of a 20-hour program and primary care. When dealing with chronic back pain, low-intensity multidisciplinary treatment yields no significantly better results than standard care and monodisciplinary therapy; however, high-intensity treatment does. For multidisciplinary headache treatment, such comparisons are not yet available. In a previous study undertaken by our Pain Center, the outcome of a minimal multidisciplinary intervention model (20-hour) did not exceed primary care. Forty-two patients suffering from frequent headaches (20 +/- 9 headache days/month; range: 8-30) were treated and evaluated in a 96-hour group program. The results were compared with the outcomes of the previous study. Subjects who had undergone either the 20-hour multidisciplinary program or the primary care were used as historical control groups. A significant reduction in migraine days (P < .001), tension-type headache days (P < .001), frequency of migraine attacks (P = .004), and depression score (P < .001) was seen at the follow-up after 22 (+/-2) weeks. Comparing the intensive multidisciplinary program with primary care, repeated measures ANOVAs revealed significant time x group interactions for migraine days (P = .020), tension-type headache days (P = .016), and frequency of migraine attacks (P = .016). In comparison with the 20-hour multidisciplinary program, the 96-hour program showed significantly better effects only in the reduction of migraine days (P = .037) and depression score (P = .003). The responder-rates (> or =50% improvement) in the 96-hour program were significantly higher than in the 20-hour program (migraine days, P = .008; tension-type headache days, P = .044) and primary care (migraine days, P = .007; tension-type headache days, P = .003; tension-type headache intensity, P = .037). The effect sizes were small to medium in the 96-hour program. Particularly with the reduction of migraine symptomatology, the 96-hour program performed better than the 20-hour program, which produced only negligible or small effects. Intensive multidisciplinary headache treatment is highly effective for patients with chronic headaches. Furthermore, migraine symptomatology responds especially well to this intensive treatment program, whereas effects on tension-type headaches were realized by both multidisciplinary programs. Randomized controlled trials and subgroup analysis are needed to find out if these results can be replicated and which patient characteristics allow for sufficient improvements for headache sufferers even with less complex treatment.

Currently, immunotherapy with Bacillus Calmette-Guerin (BCG) is the most effective treatment for superficial bladder carcinoma, but treatment-related toxicity may limit its use in some patients. Alternative treatments are needed for patients who fail to respond to BCG immunotherapy. Allium sativum (AS), or garlic, is known to have a broad range of biologic activities, including immune stimulation and reported antitumor activity. For these reasons, the authors conducted a series of experiments designed to explore the possible therapeutic effects of AS in the MBT2 murine bladder carcinoma model. C3H/HeN mice were randomized prior to initiation of each experimental protocol. Mice received 1 x 10(3) MBT2 cells in 0.1 mL RPMI-1640, administered subcutaneously into the right thigh, on Day 0 of the experiment. AS was injected at the site of tumor transplantation on Day 1 and at 2- to 7-day intervals up to Day 28. To evaluate the effects of oral AS in this model, treatment was initiated 30 days prior to tumor inoculation and continued for 30 days after tumor inoculation. Animals in all experiments were followed for tumor incidence, tumor growth, and survival. In the initial experiments, subcutaneous AS significantly reduced tumor volume compared with the saline control (P < 0.05). Unfortunately, treatment-related death was also observed, requiring reduction in the total dose of AS. Animals that received 5 weekly immunizations of AS (5 mg, 5 mg, 1 mg, 1 mg, and 1 mg; cumulative dose = 13 mg) had significantly reduced tumor incidence, tumor growth, and increased survival when compared with animals that received the saline control. No treatment-related deaths were observed with this treatment schedule. To determine whether systemic AS administration might be effective, orally administered AS was tested at doses of 5 mg, 50 mg, and 500 mg per 100 mL of drinking water. Mice that received 50 mg oral AS had significant reductions in tumor volume (P < 0.05) when compared with animals that received the saline control, and mice that received 500 mg oral AS had significant reductions in both tumor volume and mortality (P < 0.05). The significant antitumor efficacy of subcutaneous and oral AS warrants further investigation and suggests that AS may provide a new and effective form of therapy for transitional cell carcinoma of the bladder.

An open-label, parallel-group, randomized, multicenter trial was conducted to compare efficacy and safety of repaglinide versus nateglinide, when used in a combination regimen with metformin for treatment of type 2 diabetes. Enrolled patients (n = 192) had HbA(1c) >7% and < or =12% during previous treatment with a sulfonylurea, metformin, or low-dose Glucovance (glyburide < or =2.5 mg, metformin < or =500 mg). After a 4-week metformin run-in therapy period (doses escalated to 1,000 mg b.i.d.), patients were randomized to addition of repaglinide (n = 96) (1 mg/meal, maximum 4 mg/meal) or nateglinide (n = 96) (120 mg/meal, reduced to 60 mg if needed) to the regimen for 16 weeks. Glucose, insulin, and glucagon were assessed after a liquid test meal at baseline and week 16. Final HbA(1c) values were lower for repaglinide/metformin treatment than for nateglinide/metformin (7.1 vs. 7.5%). Repaglinide/metformin therapy showed significantly greater mean reductions of HbA(1c) (-1.28 vs. -0.67%; P < 0.001) and of fasting plasma glucose (FPG) (-39 vs. -21 mg/dl; P = 0.002). Self-monitoring of blood glucose profiles were significantly lower for repaglinide/metformin before breakfast, before lunch, and at 2:00 A.M. Changes in the area under the curve of postprandial glucose, insulin, or glucagon peaks after a test meal were not significantly different for the two treatment groups during this study. Median final doses were 5.0 mg/day for repaglinide and 360 mg/day for nateglinide. Safety assessments were comparable for the two regimens. The addition of repaglinide to metformin therapy resulted in reductions of HbA(1c) and FPG values that were significantly greater than the reductions observed for addition of nateglinide.

Multiple devices are currently on the market that employ radiofrequency to non-invasively treat skin laxity and wrinkle reduction. The study device was a unique monopolar radiofrequency device FDA cleared for the treatment of wrinkles and rhytids. The delivery system allows constant monitoring of the real-time local skin impedance changes, which allows radiofrequency energy to be more uniformly dosed over an entire treatment area. The objective was to validate effectiveness of a modified treatment protocol for a unique monopolar radiofrequency device, which has been engineered with greater power and self-monitoring circuitry. Twenty-four female subjects received bilateral monopolar radiofrequency treatments to the mid and lower face from the sub malar region to the submentum. Subjects completed 1 and 3 month follow ups with digital imaging. Skin biopsies (on 4 subjects) and ultrasound measurements (on 12 subjects) were completed. Assessments demonstrated a reduction in skin laxity of 35%, a reduction in fine lines/wrinkles of 42%, and a reduction in the appearance of global photodamage of 33%. Expert photograding demonstrated 92% of subjects showing at least a mild improvement in skin laxity at three months post treatment. 50 MHz ultrasound measurements in 12 subjects showed an increase of 19% in skin density. Histology showed a marked increase in dermal collagen and elastin fibers in two subjects who demonstrated a clinically noticeable reduction in skin laxity and minimal changes in two subjects who demonstrated minimal clinical improvements. There were no significant adverse events reported. This modified radiofrequency device and treatment protocol was well tolerated and produced improvements in the appearance of skin laxity and overall anti-aging effects in the majority of subjects. Objective measurements including ultrasound and histology help explain the clinical outcome.

To evaluate the efficacy of remote nonpainful electrical upper arm skin stimulation in reducing migraine attack pain. This is a prospective, double-blinded, randomized, crossover, sham-controlled trial. Migraineurs applied skin electrodes to the upper arm soon after attack onset for 20 minutes, at various pulse widths, and refrained from medications for 2 hours. Patients were asked to use the device for up to 20 attacks. In 71 patients (299 treatments) with evaluable data, 50% pain reduction was obtained for 64% of participants based on best of 200-μs, 150-μs, and 100-μs pulse width stimuli per individual vs 26% for sham stimuli. Greater pain reduction was found for active stimulation vs placebo; for those starting at severe or moderate pain, reduction (1) to mild or no pain occurred in 58% (25/43) of participants (66/134 treatments) for the 200-μs stimulation protocol and 24% (4/17; 8/29 treatments) for placebo ( p = 0.02), and (2) to no pain occurred in 30% (13/43) of participants (37/134 treatments) and 6% (1/17; 5/29 treatments), respectively ( p = 0.004). Earlier application of the treatment, within 20 minutes of attack onset, yielded better results: 46.7% pain reduction as opposed to 24.9% reduction when started later ( p = 0.02). Nonpainful remote skin stimulation can significantly reduce migraine pain, especially when applied early in an attack. This is presumably by activating descending inhibition pathways via the conditioned pain modulation effect. This treatment may be proposed as an attractive nonpharmacologic, easy to use, adverse event free, and inexpensive tool to reduce migraine pain. NCT02453399. This study provides Class III evidence that for patients with an acute migraine headache, remote nonpainful electrical stimulation on the upper arm skin reduces migraine pain. © 2017 American Academy of Neurology.

This study integrates push-pull tracer tests (PPTT) with microbial characterization of extracted water via quantitative polymerase chain reaction (qPCR) and reverse transcriptase qPCR (RT-qPCR) of selected functional N transformation genes to quantify nitrate reduction mechanisms and rates in sites with different redox potential in a karst aquifer. PPTT treatments with nitrate (AN) and nitrate-fumarate (ANC) were executed in two wells representing anoxic and oxic geochemical end-members. Oxic aquifer zero-order nitrate loss rates (mmol L-1 h-1) were similar for AN and ANC treatment, ranging from 0.03 ± 0.01 to 0.05 ± 0.01. Anoxic aquifer zero-order nitrate loss rates ranged from 0.03 ± 0.02 (AN) to 0.13 ± 0.02 (ANC). Microbial characterization indicates mechanisms influencing these rates were dissimilatory nitrate reduction to ammonium (DNRA) at the anoxic site with AN treatment, assimilatory reduction of nitrate to ammonium (ANRA) with ANC treatment in the water column at both sites, and additional documented nitrate reduction that occurred in unsampled biofilms. With carbon treatment, total numbers of microbes (16S rRNA genes) significantly increased (fourteenfold to thirtyfold), supporting stimulated growth with resulting ANRA. Decreased DNRA gene concentrations (nrfA DNA) and increased DNRA activity ratio (nrfA-cDNA/DNA) supported the assertion that DNRA occurred in the anoxic zone with AN and ANC treatment. Furthermore, decreased DNRA gene copy numbers at the anoxic site with ANC treatment suggests that DNRA microbes in the anoxic site are chemolithoautotrophic. Increased RT-qPCR denitrification gene expression (nirK and nirS) was not observed in water samples, supporting that any observed NO3-N loss due to denitrification may be occurring in unsampled microbial biofilms.

Drought stress during grain development causes significant yield loss in cereal production. The phosphorylated modification of starch granule-binding proteins (SGBPs) is an important mechanism regulating wheat starch biosynthesis. In this study, we performed the first proteomics and phosphoproteomics analyses of SGBPs in elite Chinese bread wheat (Triticum aestivum L.) cultivar Jingdong 17 under well-watered and water-stress conditions. Water stress treatment caused significant reductions in spike grain numbers and weight, total starch and amylopectin content, and grain yield. Two-dimensional gel electrophoresis revealed that the quantity of SGBPs was reduced significantly by water-deficit treatment. Phosphoproteome characterization of SGBPs under water-deficit treatment demonstrated a reduced level of phosphorylation of main starch synthesis enzymes, particularly for granule-bound starch synthase (GBSS I), starch synthase II-a (SS II-a), and starch synthase III (SS III). Specifically, the Ser34 site of the GBSSI protein, the Tyr358 site of SS II-a, and the Ser837 site of SS III-a exhibited significant less phosphorylation under water-deficit treatment than well-watered treatment. Furthermore, the expression levels of several key genes related with starch biosynthesis detected by qRT-PCR were decreased significantly at 15 days post-anthesis under water-deficit treatment. Immunolocalization showed a clear movement of GBSS I from the periphery to the interior of starch granules during grain development, under both water-deficit and well-watered conditions. Our results demonstrated that the reduction in gene expression or transcription level, protein expression and phosphorylation levels of starch biosynthesis related enzymes under water-deficit conditions is responsible for the significant decrease in total starch content and grain yield.

Laparoscopic sleeve gastrectomy is a surgical procedure for the treatment of morbid obesity. However, there are still controversies regarding its efficiency in terms of weight reduction and incidence of complications. In this prospective study, the experience is presented of a referral centre for the treatment of morbid obesity with laparoscopic sleeve gastrectomy. A prospective study on 73 patients subjected to laparoscopic sleeve gastrectomy from February 2009 to September 2013. Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Lisfranc injuries involve any bony or ligamentous disruption of the tarsometatarsal joint. Outcome results after treatment are mainly evaluated using patient-reported outcome measures (PROM), physical examination and radiographic findings. Less is known about the kinematics during gait. Nineteen patients (19 feet) treated for Lisfranc injury were recruited. Patients with conservative treatment and surgical treatment consisting of open reduction and internal fixation (ORIF) or primary arthrodesis were included. PROM, radiographic findings and gait analysis using the Oxford Foot Model (OFM) were analysed. Results were compared with twenty-one healthy subjects (31 feet). Multivariable logistic regression was used to determine factors influencing outcome. Patients treated for Lisfranc injury had a significantly lower walking speed than healthy subjects (P<0.001). There was a significant difference between the two groups regarding the range of motion (ROM) in the sagittal plane (flexion-extension) in the midfoot during the push-off phase (p<0.001). The ROM in the sagittal plane was significantly correlated with the AOFAS midfoot score (r 2 =0.56, p=0.012), FADI (r 2 =0.47, p=0.043) and the SF-36-physical impairment score (r 2 =0.60, p=0.007) but not with radiographic parameters for quality of reduction. In a multivariable analysis, the best explanatory factors were ROM in the sagittal plane during the push-off phase (β=0.707, p=0.001), stability (β=0.423, p=0.028) and BMI (β=-0.727 p=<0.001). This prediction model explained 87% of patient satisfaction. This study showed that patients treated for Lisfranc injury had significantly lower walking speed and significantly lower flexion/extension in the midfoot than healthy subjects. The ROM in these patients was significantly correlated with PROM, but not with radiographic quality of reduction. Most important satisfaction predictors were BMI, ROM in the sagittal plane during the push-off phase and fracture stability. Copyright © 2017. Published by Elsevier Ltd.

Organic acids for control of Salmonella in different feed materials

PubMed Central

2013-01-01

Background Salmonella control in animal feed is important in order to protect animal and public health. Organic acids is one of the control measures used for treatment of Salmonella contaminated feed or feed ingredients. In the present study, the efficacy of formic acid (FA) and different blends of FA, propionic acid (PA) and sodium formate (SF) was investigated. Four Salmonella strains isolated from feed were assayed for their acid tolerance. Also, the effect of lower temperatures (5°C and 15°C) compared to room temperature was investigated in rape seed and soybean meal. Results The efficacy of acid treatments varied significantly between different feed materials. The strongest reduction was seen in pelleted and compound mash feed (2.5 log10 reduction) followed by rapeseed meal (1 log10 reduction) after 5 days exposure. However, in soybean meal the acid effects were limited (less than 0.5 log10 reduction) even after several weeks’ exposure. In all experiments the survival curves showed a concave shape, with a fast initial death phase followed by reduction at a slower rate during the remaining time of the experiment. No difference in Salmonella reduction was observed between FA and a blend of FA and PA, whereas a commercial blend of FA and SF (Amasil) was slightly more efficacious (0.5-1 log10 reduction) than a blend of FA and PA (Luprocid) in compound mash feed. The Salmonella Infantis strain was found to be the most acid tolerant strain followed by, S. Putten, S. Senftenberg and S. Typhimurium. The tolerance of the S. Infantis strain compared with the S. Typhimurium strain was statistically significant (p<0.05). The lethal effect of FA on the S. Typhimurium strain and the S. Infantis strain was lower at 5°C and 15°C compared to room temperatures. Conclusions Acid treatment of Salmonella in feed is a matter of reducing the number of viable bacterial cells rather than eliminating the organism. Recommendations on the use of acids for controlling Salmonella in feed should take into account the relative efficacy of acid treatment in different feed materials, the variation in acid tolerance between different Salmonella strains, and the treatment temperature.

The aim of this study was to evaluate the efficacy of Cognitive Evolutionary Therapy (CET) in an intensive short residential treatment of a wide range of severe personality disorders (PDs) that resulted in a reduction of social functioning and significant personal distress. Each patient was assessed at admission, discharge, and 3 months later in order to determine if there was a reduction in symptoms and an improved adherence to former outpatient programs and to check if patients were undergoing new treatment after discharge. Fifty-one patients participated in this study. The 20-hr weekly program consisted of two individual sessions and various group modules. Outcome measures included: self-reported measures of depression, anxiety, general symptoms, number and duration of inpatient admissions after the programme, and continuation in an outpatient treatment programme. The results show an overall improvement in general psychopathology after the release and in follow-up sessions, a decrease in the number of further hospital admissions, and an increased level of attendance of outpatient therapy. This study shows that intensive short residential treatment is an effective treatment for patients with a wide range of PDs. © 2012 The British Psychological Society.

Opiate treatment for opiate withdrawal in newborn infants.

Neonatal abstinence syndrome (NAS) due to opiate withdrawal may result in disruption of the mother-infant relationship, sleep-wake abnormalities, feeding difficulties, weight loss and seizures. Treatments used to ameliorate symptoms and reduce morbidity include opiates, sedatives and non-pharmacological treatments. To assess the effectiveness and safety of using an opiate, compared to a sedative or non-pharmacological treatment, for treatment of NAS due to withdrawal from opiates. The evidence for use of different opiates was assessed in subgroup analyses. The standard search strategy of the Cochrane Neonatal Review Group including searches (up to March 2002) of the Oxford Database of Perinatal Trials, Cochrane Controlled Trials Register (The Cochrane Library, Issue 1, 2002), MEDLINE (1966-March 2002), previous reviews including cross references, abstracts, conferences and symposia proceedings, expert informants, journal handsearching mainly in the English language. Trials enrolling infants with NAS born to mothers with an opiate dependence, with > 80% follow up and using random or quasi-random allocation to opiate or control. Control could include an opiate, sedative or non-pharmacological treatment. Each author assessed study quality and extracted data independently. Primary outcomes included control of symptoms, seizure occurrence, mortality and neurodevelopment. Treatment effect was expressed using relative risk (RR), risk difference (RD), mean difference (MD) and weighted mean difference (WMD). Meta-analysis was performed using a fixed effect model. Six studies enrolling a total of 511 infants met inclusion criteria (Carin 1983, Finnegan 1984, Kaltenbach 1986, Kandall 1983, Khoo 1995, Madden 1977); however, two (Finnegan 1984, Kaltenbach 1986) may be sequential reports that include some identical patients. The studies enrolled infants of mothers who had used opiates with or without other drugs during pregnancy. Methodological concerns included the use of quasi-random rather than random patient allocation methods in three studies, and sizeable, largely unexplained differences in reported numbers allocated to each group in four studies. Opiate (morphine) vs supportive care only: One study (Khoo 1995) found no significant effect on treatment failure (RR 1.29, 95% CI 0.41, 4.07), a significant increase in hospital stay (MD 15.0 days, 95% CI 8.9, 21.1) and significant reductions in time to regain birthweight (MD -2.8 days, 95% -5.3, -0.3) and duration of supportive care (MD -197.2 minutes/day, 95% CI -274.2, -120.3). Opiate vs phenobarbital: Meta-analysis of three studies found no significant difference in treatment failure (typical RR 0.78, 95% CI 0.46, 1.32). One of these studies (Finnegan 1984) reported that opiate treatment resulted in a significant reduction in treatment failure among infants of mothers who had used only opiates; however, as this was a post-hoc analysis, this result should be interpreted with caution. One study (Kandall 1983) reported a reduction in seizures, of borderline statistical significance, with the use of opiate. Opiate vs diazepam: Meta-analysis of two studies found a significant reduction in treatment failure (RR 0.43, 95% CI 0.23, 0.80) with the use of opiate. No study reported neurodevelopment by allocated treatment group. Opiates, as compared to supportive care only, appear to reduce the time to regain birth weight and reduce the duration of supportive care, but increase the duration of hospital stay; there is no evidence of effect on treatment failure. When compared to phenobarbital, opiates may reduce the incidence of seizures but, overall, there is no evidence of effect on treatment failure. When compared to diazepam, opiates reduce the incidence of treatment failure. A post-hoc analysis generates the hypothesis that treatment effects may vary according to whether the population includes infants born to all opiate users (i.e. with or without other drug exposure) or is restricted to infants of mothers who used opiates only. In view of the methodologic limitations of the included studies the conclusions of this review should be treated with caution. Further research is needed.

Abstract Eliglustat, an oral substrate reduction therapy, is a first‐line treatment for adults with Gaucher disease type 1 (GD1) who are poor, intermediate, or extensive CYP2D6 metabolizers (>90% of patients). In the primary analysis of the Phase 3 ENGAGE trial (NCT00891202), eliglustat treatment for 9 months resulted in significant reductions in spleen and liver volumes and increases in hemoglobin concentration and platelet count compared with placebo. We report 18‐month outcomes of patients who entered the trial extension period, in which all patients received eliglustat. Of 40 trial patients, 39 entered the extension period, and 38 completed 18 months. Absolute values and percent change over time were determined for spleen and liver volume, hemoglobin concentration, platelet count, bone mineral density, bone marrow burden, and Gaucher disease biomarkers. For patients randomized to eliglustat in the double‐blind period, continuing treatment with eliglustat for 9 more months resulted in incremental improvement of all disease parameters. For patients randomized to placebo in the double‐blind period, eliglustat treatment during the 9‐month, open‐label period resulted in significant decrease of spleen and liver volumes and significant increase of hemoglobin and platelets, with a similar rate of change to patients who had received eliglustat in the double‐blind period. Eliglustat treatment was also associated with improvement in bone marrow burden score, bone mineral density, and established biomarkers of Gaucher disease, including reduction of the bioactive lipid, glucosylsphingosine. These findings underscore the efficacy of eliglustat in treatment‐naïve patients. Eliglustat was well‐tolerated, and there were no new safety concerns with longer‐term exposure. PMID:28762527

Subclinical, chronic tissue inflammation involving the generation of cytokines (e.g., interleukin-6 and tumor necrosis factor-alpha) might contribute to the cutaneous aging process. This study aims to screen for an active ingredient with anti-inflammatory (i.e., reduction of interleukin-6 and tumor necrosis factor-alpha) and matrix-stimulating efficacy which improves the clinical signs of skin aging in vivo. In vitro studies with pure Arctiin were performed investigating the inhibition of cytokine induction and stimulation of collagen neo-synthesis. In vivo home-in-use studies using an Arctium lappa fruit extract-containing formulation were carried out to determine procollagen and hyaluronan synthesis, hyaluronan synthase-2 gene expression, and reduction of wrinkle volume after treatment. In vitro studies on human dermal fibroblasts and monocyte-derived dendritic cells supplemented with pure Arctiin showed relative to untreated control cells a stimulation of collagen synthesis and a decrease in interleukin-6 and tumor necrosis factor-alpha concentration, respectively. In addition, topical in vivo application of an A. lappa fruit extract-containing formulation for 12 weeks significantly stimulated procollagen synthesis and increased hyaluronan synthase-2 expression as well as hyaluronan levels compared to vehicle-treated control areas. Similarly, after a 4-week treatment with an A. lappa fruit extract-containing formulation, wrinkle volume in the crow's feet area was significantly reduced as compared to treatment with the vehicle. Our data show that topical treatment with a natural A. lappa fruit extract significantly improves the metabolism of the dermal extracellular matrix and leads to a visible wrinkle reduction in vivo. In conclusion, A. lappa fruit extract represents a targeted means to regenerate dermal structures and, thus, offers an effective treatment option for mature skin.

The aim of this study was to perform a meta-analysis of the effects of sanitizing treatments of fresh produce on Salmonella spp., Escherichia coli O157:H7, and Listeria monocytogenes. From 55 primary studies found to report on such effects, 40 were selected based on specific criteria, leading to more than 1,000 data on mean log reductions of these three bacterial pathogens impairing the safety of fresh produce. Data were partitioned to build three meta-analytical models that could allow the assessment of differences in mean log reductions among pathogens, fresh produce, and sanitizers. Moderating variables assessed in the meta-analytical models included type of fresh produce, type of sanitizer, concentration, and treatment time and temperature. Further, a proposal was done to classify the sanitizers according to bactericidal efficacy by means of a meta-analytical dendrogram. The results indicated that both time and temperature significantly affected the mean log reductions of the sanitizing treatment (P < 0.0001). In general, sanitizer treatments led to lower mean log reductions when applied to leafy greens (for example, 0.68 log reductions [0.00 to 1.37] achieved in lettuce) compared to other, nonleafy vegetables (for example, 3.04 mean log reductions [2.32 to 3.76] obtained for carrots). Among the pathogens, E. coli O157:H7 was more resistant to ozone (1.6 mean log reductions), while L. monocytogenes and Salmonella presented high resistance to organic acids, such as citric acid, acetic acid, and lactic acid (∼3.0 mean log reductions). With regard to the sanitizers, it has been found that slightly acidic electrolyzed water, acidified sodium chlorite, and the gaseous chlorine dioxide clustered together, indicating that they possessed the strongest bactericidal effect. The results reported seem to be an important achievement for advancing the global understanding of the effectiveness of sanitizers for microbial safety of fresh produce. PMID:26362982

Cin, D.A.; Kroger, M.

Concentrations of the chlorinated hydrocarbon insecticide mirex (C/sub 10/Cl/sub 12/) were determined in brown trout from a defined contaminated area of Spring Creek, Centre County, PA, using electron-capture gas chromatography. Conventional heat treatments, namely, baking, frying, poaching, and baking without skin, did not cause significant decreases of the contaminant. Ultraviolet irradiation led to significant reductions (p < 0.05) in mirex concentration in muscle tissue. Exposures of 24, 48, and 72 hr led to degradations of 30.0%, and 45.6%, respectively, of the initial mirex concentration. Gamma irradiation also led to significant reductions (p < 0.05) in mirex concentration in muscle tissue.more » Following absorption of 1, 3, and 5 Mrad, degradations of 9.8%, 23,1%, and 37.5%, respectively, of the initial mirex concentration were observed.« less

Psoriasis is a common disorder affecting 1-3 percent of the general global population. Many therapeutic modalities have been suggested for treatment of this condition, but still there is no definite treatment for this disease. The objective in this study was to evaluate the efficacy of topical azelaic acid gel versus placebo in the treatment of psoriasis vulgaris. This study was a single-blinded randomized clinical trial. Overall, 31 patients were selected and the left or right sided lesions of the patients were randomized to receive either 15% azelaic acid or gel twice daily for a one-month period. Two symmetrical lesions with almost similar severity in every patient were selected and considered as index lesions to evaluate lesion response to treatment. The severity of erythema, scaling, hyperkeratosis and pruritus of the index lesions were scored in range of 0-3 for each lesion by the investigator at the baseline and follow up visits. The percent of involvement of each side of body was also measured using rule of nines. The collected data were analyzed using statistical tests including Mann-Whitney and ANOVA tests. There was no significant difference between the two groups before treatment (P > 0.05). After treatment, however, except pruritus, there was significant difference between the two groups (P < 0.05). There was no significant difference regarding total psoriasis score between the two groups before treatment (P > 0.05). After treatment, however, there was significant difference between the two groups (P < 0.05) in favor of more efficacy for azelaic acid. There was no significant difference regarding percent of body involvement between the two groups before treatment (P > 0.05). After treatment, however, there was a significant difference between the two groups (P < 0.05) in favor of more efficacy on the part of azelaic acid gel. The results of our study showed that 15% azelaic acid gel was effective in reduction of purities, scaling and hyperkeratosis of psoriasis plaques. This treatment was also effective in reduction of skin involvement with psoriasis. It is recommended that a longer study be performed that can better evaluate the efficacy of this treatment against plaque-type psoriasis.

The effectiveness of an individualized outpatient program was investigated in the treatment of bulimia nervosa (BN) and anorexia nervosa (AN). Participants included 151 females who received outpatient eating disorder treatment in the partial hospitalization program, the intensive outpatient program, or a combination of the two programs. Outcome measures included the Eating Disorder Inventory (EDI-2), Beck Depression Inventory (BDI-II), frequency of binge eating and purging, and mean body weight. Findings included significant increases in weight for the AN group, reductions in binge eating frequency for the BN group, and reductions in EDI-2 and BDI-II scores and purging frequency for both groups. This study provides preliminary support for the efficacy of a multimodal program for the treatment of both anorexia nervosa and bulimia nervosa.

Only 30 percent of chronic diabetic foot ulcers heal after 20 weeks of standard treatment. Pirfenidone is a drug with biological, anti-inflammatory, and antifibrotic effects. The aim of this study was to evaluate the effect of topical pirfenidone added to conventional treatment in noninfected chronic diabetic foot ulcers. This was a randomized crossover study. Group 1 received topical pirfenidone plus conventional treatment for 8 weeks; after this period, they were switched to receive conventional treatment only for 8 more weeks. In group 2, the order of the treatments was the opposite. The end points were complete ulcer healing and size reduction. Final data were obtained from 35 ulcers in 24 patients. Fifty-two percent of ulcers treated with pirfenidone healed before 8 weeks versus 14.3% treated with conventional treatment only (P = 0.025). Between 8 and 16 weeks, 30.8% ulcers that received pirfenidone healed versus 0% with conventional treatment (P = 0.081). By week 8, the reduction in ulcer size was 100% [73–100] with pirfenidone versus 57.5% with conventional treatment [28.9–74] (P = 0.011). By week 16, the reduction was 93% [42.7–100] with pirfenidone and 21.8% [8–77.5] with conventional treatment (P = 0.050). The addition of topical pirfenidone to conventional treatment significantly improves the healing of chronic diabetic noninfected foot ulcers. PMID:27478849

Purpose of review EDTA chelation therapy has been in off-label use for the treatment of atherosclerosis. We review the results of the first large-scale randomized trial of this treatment. Recent findings The trial to assess chelation therapy was a $30 million National Institutes of Health-funded study of the safety and efficacy of EDTA-based chelation infusions in 1708 post-myocardial infarction (MI) patients. The trial to assess chelation therapy demonstrated a significant (P = 0.035) 18% reduction in a combined primary endpoint of death, MI, stroke, coronary revascularization, or hospitalization for angina. In diabetic patients the benefit was more extreme, with a 41% relative reduction in risk (P = 0.0002) and a 43% reduction in total mortality (P = 0.011). Safety data were favorable. A reduction of oxidative stress by chelation of toxic metals has been proposed as a possible mechanism of action. Summary Recent research suggests that EDTA chelation may be a well-tolerated and effective treatment for post-MI patients. Future replication and mechanistic studies are important prior to implementation in all post-MI patients. PMID:25023079

Usage patterns and effectiveness of a longer-acting formulation of insulin glargine at a strength of 300 units per milliliter (Gla-300) have not been studied in real-world clinical practice. This study evaluated differences in dosing and clinical outcomes before and after Gla-300 treatment initiation in patients with type 2 diabetes starting or switching to treatment with Gla-300 to assess whether the benefits observed in clinical trials translate into real-world settings. This was a retrospective observational study using medical record data obtained by physician survey for patients starting treatment with insulin glargine at a strength of 100 units per milliliter (Gla-100) or Gla-300, or switching to treatment with Gla-300 from treatment with another basal insulin (BI). Differences in dosing and clinical outcomes before versus after treatment initiation or switching were examined by generalized linear mixed-effects models. Among insulin-naive patients starting BI treatment, no difference in the final titrated dose was observed in patients starting Gla-300 treatment versus those starting Gla-100 treatment [least-squares (LS) mean 0.43 units per kilogram vs 0.44 units per kilogram; P = 0.77]. Both groups had significant hemoglobin A 1c level reductions (LS mean 1.21 percentage points for Gla-300 and 1.12 percentage points for Gla-100 ; both P < 0.001). The relative risk of hypoglycemic events after Gla-300 treatment initiation was lower than that after Gla-100 treatment initiation [0.31, 95% confidence interval (CI) 0.12-0.81; P = 0.018] at similar daily doses. The daily dose of BI was significantly lower after switching to treatment with Gla-300 from treatment with another BI (0.73 units per kilogram before switch vs 0.58 units per kilogram after switch; P = 0.02). The mean hemoglobin A 1c level was significantly lower after switching than before switching (adjusted difference - 0.95 percentage points, 95% CI - 1.13 to - 0.78 percentage points ; P < 0.0001). Hypoglycemic events per patient-year were significantly lower (relative risk 0.17, 95% CI 0.11-0.26; P < 0.0001). Insulin-naive patients starting Gla-300 treatment had fewer hypoglycemic events, a similar hemoglobin A 1c level reduction, and no difference in insulin dose versus patients starting Gla-100 treatment. Patients switching to Gla-300 treatment from treatment with other BIs had significantly lower daily doses of BI, with fewer hypoglycemic events, without compromise of hemoglobin A 1c level reduction. These findings suggest Gla-300 in a real-world setting provides benefits in terms of dosing, with improved hemoglobin A 1c level and hypoglycemia rates. Sanofi US Inc. (Bridgewater, NJ, USA).

This study assessed the effectiveness of 200 and 500 ppm of chlorine and organic acids (0.5% lactic acid and 0.5% citric acid) in wash solutions, and UV radiation for reducing Escherichia coli O157:H7 and Yersinia enterocolitica on apples contaminated by two different methods. Residual levels of these pathogens after different treatments were compared. On dip inoculated apples, Y. enterocolitica reductions of 2.66 and 2.77 logs were obtained with 200 and 500 ppm chlorine combined with 0.5% lactic acid, respectively. The E. coli O157:H7 population decreased 3.35 log with 0.5% lactic acid wash solution, and 2.72 and 2.62 logs after 500 ppm chlorine and 500 ppm chlorine plus 0.5% lactic acid treatments, respectively. Similar reductions were obtained with UV radiation. On spot inoculated apples, significant (p < 0.05) decreases of 4.67 and 4.58 logs were observed in E. coli O157:H7 and Y. enterocolitica levels, respectively, after 500 ppm chlorine plus 0.5% lactic acid treatment as compared with the control. In sectioned apples, microorganisms infiltrated in inner core region and pulp were not significantly (p < 0.05) affected by disinfection treatments. No pathogens were detected in the natural microflora on apples. Reductions such as those obtained with 500 ppm chlorine plus 0.5% lactic acid solution were very proximal to the 5-log score required by FDA for apple disinfection.

Accumulation of dechlorination daughter products: A valid metric of chloroethene biodegradation

USGS Publications Warehouse

Bradley, Paul M.; Chapelle, Frank H.

2007-01-01

In situ reductive dechlorination of perchloroethene (PCE) and trichloroethene (TCE) generates characteristic chlorinated (cis-dichloroethene [cis-DCE] and vinyl chloride [VC]) and nonchlorinated (ethene and ethane) products. The accumulation of these daughter products is commonly used as a metric for ongoing biodegradation at field sites. However, this interpretation assumes that reductive dechlorination is the only chloroethene degradation process of any significance in situ and that the characteristic daughter products of chloroethene reductive dechlorination persist in the environment. Laboratory microcosms, prepared with aquifer and surface-water sediments from hydrologically diverse sites throughout the United States and amended with [1,2-14C] TCE, [1,2-14C] DCE, [1,2-14C] DCA, or [1,2-14C] VC, demonstrated widely variable patterns of intermediate and final product accumulation. In predominantly methanogenic sediment treatments, accumulation of 14C-DCE, 14C-VC, 14C-ethene, and 14C-ethane predominated. Treatments characterized by significant Fe(III) and/or Mn(IV) reduction, on the other hand, demonstrated substantial, and in some cases exclusive, accumulation of 14CO2and 14CH4. These results suggest that relying on the accumulation of cis-DCE, VC, ethene, and ethane may substantially underestimate overall chloroethene biodegradation at many sites.

Cryosurgery with liquid nitrogen is one of the most used treatments for actinic keratosis. We aimed to study the effectiveness of two consecutive sessions of cryosurgery for actinic keratosis and investigate factors associated with its therapeutic success. Hence, we conducted a longitudinal study including 92 patients of both sexes, aged 50-75 years with 5-50 actinic keratosis on the face and forearms, who underwent cryosurgery and treatment with sunscreen SPF 30, at baseline and after 120 days. The lesions were counted in duplicate by the same examiner before the start of treatment and after 120 (N=92) and 300 days (N=33), represented by their medians and quartiles and compared using the generalized linear mixed effects model (negative binomial). Treatment behavior was investigated in relation to sex, age, education, skin type, smoking, sun exposure at work and the use of aspirin, anti-inflammatory and angiotensin-converting enzyme inhibitors. There was a significant reduction in the actinic keratosis count on the face and forearms (p<0.05). Our results confirmed the effectiveness of cryosurgery for actinic keratosis, with a 57% reduction in the number, and size of the lesions. Higher education levels (p=0.02) and less sun exposure at work (p=0.02) independently promoted a significant reduction in the actinic keratosis count. Different population groups showed characteristic responses to the treatment, which may be explained by the degree of adherence to the use of photoprotection. In two sessions, cryosurgery with liquid nitrogen reduced the actinic keratosis count. Copyright © 2014 Elsevier Inc. All rights reserved.

The aim of the study was to evaluate the short and long-term effects of acupuncture on vasomotor symptoms (VMS) and quality of life-related measures. A total of 209 perimenopausal and postmenopausal women aged 45 to 60 years, experiencing four or more VMS per day, were recruited from the community and randomized to receive up to 20 acupuncture treatments within the first 6 months (acupuncture group) or the second 6 months (waitlist control group) of the 12-month study period. The primary outcome was mean daily frequency of VMS. Secondary outcomes were VMS interference with daily life, sleep quality, depressive symptoms, somatic and other symptoms, anxiety, and quality of life. The VMS frequency declined by 36.7% at 6 months in the acupuncture group and increased by 6.0% in the control group (P < 0.001 for between-group comparison). At 12 months, the reduction from baseline in the acupuncture group was 29.4% (P < 0.001 for within-group comparison from baseline to 12 months), suggesting that the reduction was largely maintained after treatment. Statistically significant clinical improvement was observed after three acupuncture treatments, and maximal clinical effects occurred after a median of eight treatments. Persistent improvements were seen in many quality of life-related outcomes in the acupuncture group relative to the control group. We found that a course of acupuncture treatments was associated with significant reduction in VMS, and several quality-of-life measures, compared with no acupuncture, and that clinical benefit persisted for at least 6 months beyond the end of treatment.

Objective: To evaluate the safety and effectiveness of different bipolar radiofrequency system algorithms in interrupting the renal sympathetic nerves and reducing renal norepinephrine in a healthy porcine model. Methods: A porcine model (N = 46) was used to investigate renal norepinephrine levels and changes to renal artery tissues and nerves following percutaneous renal denervation with radiofrequency bipolar electrodes mounted on a balloon catheter. Parameters of the radiofrequency system (i.e. electrode length and energy delivery algorithm), and the effects of single and longitudinal treatments along the artery were studied with a 7-day model in which swine received unilateral radiofrequency treatments. Additional sets of animals were used to examine norepinephrine and histological changes 28 days following bilateral percutaneous radiofrequency treatment or surgical denervation; untreated swine were used for comparison of renal norepinephrine levels. Results: Seven days postprocedure, norepinephrine concentrations decreased proportionally to electrode length, with 81, 60 and 38% reductions (vs. contralateral control) using 16, 4 and 2-mm electrodes, respectively. Applying a temperature-control algorithm with the 4-mm electrodes increased efficacy, with a mean 89.5% norepinephrine reduction following a 30-s treatment at 68°C. Applying this treatment along the entire artery length affected more nerves vs. a single treatment, resulting in superior norepinephrine reduction 28 days following bilateral treatment. Conclusion: Percutaneous renal artery application of bipolar radiofrequency energy demonstrated safety and resulted in a significant renal norepinephrine content reduction and renal nerve injury compared with untreated controls in porcine models.

A new waterless surgical hand preparation containing 1% chlorhexidine gluconate (CHG) and 61% ethyl alcohol was evaluated for antimicrobial efficacy in comparison with a standard 4% CHG surgical scrub and a 61% ethyl alcohol control. Clinical studies were based on the Tentative Final Monograph for Health-Care Antiseptic Drug Products (TFM) (proposed rule) and the Standard Test Method for Evaluation of Surgical Hand Scrub Formulations (ASTM E1115-91). Two randomized, blinded, well-controlled clinical studies involving 137 healthy subjects were conducted to evaluate the antimicrobial effectiveness of the CHG/ethanol hand preparation in producing an immediate and persistent reduction in the normal bacterial flora of the hands. The CHG/ethanol hand preparation was applied without scrubbing or the use of water, and a standard 4% CHG reference product was applied with a scrub brush in 2 traditional 3-minute surgical scrubs. In 1 study, a 61% ethanol vehicle control treatment was applied without scrubbing or use of water. During a 5-day period, each study subject performed a series of 11 surgical scrubs with 1 of the test treatments. After the first treatment on days 1, 2, and 5, surgical gloves were worn for 3 or 6 hours. Bacterial samples were taken with the glove-juice technique at 1 minute, 3 hours, and 6 hours after treatment. The immediate bactericidal effect of the CHG/ethanol hand preparation after a single application resulted in a 2.5-log reduction in normal flora. This bactericidal effect persisted throughout the studies and eventually increased to a 3.6-log reduction after the 11th scrub on day 5. The log reductions of the CHG/ethanol hand preparation proved to be significantly better (P <.05) than that of the 4% CHG product at each sampling interval on days 1 and 2 and the sampling at 6 hours on day 5 and significantly better than the 61% ethanol vehicle at all times. The combination of 1% CHG and 61% ethanol had significantly greater microbial reduction than either the 4% CHG (without ethanol) or the 61% ethanol vehicle (without CHG).

Fractional CO2 -laser resurfacing is increasingly used for treating rhytides and photoaged skin because of its favorable benefit-risk ratio. A key outcome measure and treatment goal in aesthetic laser therapy is patient satisfaction. However, few data are available on patient-reported outcomes after fractional ablative skin-resurfacing. To compare patient expectations before and patient satisfaction after three fractional CO2 -laser treatments and to correlate objectively measured wrinkle reduction with patient satisfaction after treatment. We investigated patient expectation and satisfaction using a 14-item questionnaire in 24 female patients. We assessed the skin-related quality of life and patient satisfaction with skin appearance. We profilometrically measured wrinkle size in four facial areas before and three months after treatment and investigated correlations between wrinkle reduction and patient satisfaction. The high patient expectations before treatment (ceiling effect) were actually slightly exceeded. The average score of 14 items delineating patient satisfaction with laser treatment was higher (4.64 ± 0.82; n = 24) than the respective expectations before treatment (4.43 ± 0.88; n = 24). Skin-related quality of life and patient satisfaction with skin appearance had significantly improved after the last treatment. Patients dissatisfied with their skin appearance before treatment (mean 2.1 ± 1.5; evaluated on a scale ranging from 0-6) were satisfied (mean 5.1 ± 1.2) (P < 0.001) with skin appearance at the follow-up. Patient satisfaction with skin appearance was not correlated to the profilometrically measured reduction of wrinkle size of any facial area. Our results show high patient satisfaction with ablative fractional skin resurfacing, also regarding improved self-esteem and self-satisfaction despite high pre-treatment expectations. Skin-specific quality of life had significantly improved. Thus, this treatment modality can be recommended for patients with photoaged skin wishing to improve skin appearance. © 2015 Wiley Periodicals, Inc.

Objective The goal of the present investigation was to develop and test a brief therapist-guided manualized treatment for problematic caffeine use including cognitive-behavioral strategies and 5-weeks of progressively decreased consumption. Methods Individuals seeking treatment for problematic caffeine use (mean daily caffeine consumption of 666.0 mg at baseline) were randomized using a waitlist-control design to receive immediate (N = 33) treatment or delayed (N = 34) treatment (∼6 weeks later). A one-hour long treatment session designed to help individuals quit or reduce caffeine consumption was provided by a trained counselor along with a take-home booklet. After the treatment session, participants completed daily diaries of caffeine consumption for 5 weeks. They returned for follow-up assessments at 6, 12, and 26 weeks and had a telephone interview at 52-weeks post-treatment. Results Treatment resulted in a significant reduction in self reported caffeine use and salivary caffeine levels. No significant post-treatment increases in caffeine use were observed for up to one year follow-up. Comparisons to the waitlist control condition revealed that reductions in caffeine consumption were due to treatment and not the passing of time, with a treatment effect size of R2 = .35 for the model. Conclusions A brief one-session manualized intervention with follow-up was efficacious at reducing caffeine consumption. Future research should replicate and extend these findings, as well as consider factors affecting dissemination of treatment for problematic caffeine use to those in need. PMID:26501499

To investigate the efficacy and complications of manual reduction and external fixation for the treatment of scaphoid fractures and perilunate dislocations. From January 2009 to January 2013, 43 patients suffered from scaphoid fractures and perilunate dislocations were retrospective analyzed. Among them, 17 cases were treated with manipulative reduction and plaster external fixation as conservation group including 10 males and 7 females, the other 26 cases were treated with application of surgical as operation group including 15 males and 11 females. The clinical effects were assessed by Cooney function score, radiological analysis and observation of complications. All patients were followed up for(45.00±8.72) months ranging from 36 to 60 months. At the final follow-up, the Cooney score of wrist function was 88.53±4.24 in conservation group and 89.58±4.59in operation group( t= 0.455, P >0.05). During the follow-up, 4 patients were found scaphoid avascular necrosis in the imaging performance in the conservation group(χ²=4.32, P <0.05). The difference of other complications between two groups was not statistically significant( P >0.05). For patients suffered from the scaphoid fractures and perilunate dislocation, the early manipulative reduction and plaster external fixation after injury as soon as possible is necessary. Maintaining a satisfactory reduction and reliable fixation at the same time can lead to good treatment effect and there's no weakness compared to surgical treatment. But there was an increase in danger of complications. The key of conservative treatment lies in early diagnosis and maintenance of reduction, reliable fixation, and timely and appropriate functional exercise.

This study was carried out to verify the therapeutic homogeneity between DEAE-Dextran and Cholestyramine. Blood levels of total cholesterol, HDL, LDL and triglycerides were evaluated in 202 patients affected by dyslipidemia and treated with DEAD-D at 2.5 g/day or with Cholestyramine at 12 g/day for 30 days. At the end of treatment both drugs caused significant reduction of total cholesterol, LDL and triglycerides blood levels; DEAD-D was generally more effective than Cholestyramine, in particular on triglycerides values (30.6% and 13.7% of reduction respectively), and produced also a significant increase in HDL cholesterol, differently from Cholestyramine that was ineffective on this parameter.

Background: The combination of biomaterials, bone graft substitutes along with guided tissue regeneration (GTR) has been shown to be an effective modality of periodontal regenerative therapy for infrabony defects. Therefore, the present randomized controlled clinical study was undertaken to evaluate the effectiveness of hyaluronic acid (HA) in combination with bioresorbable membrane for the treatment of human infrabony defects. Materials and Methods: Twenty four infrabony defects in 20 systemically healthy patients were randomly assigned to test (HA in combination with bioresorbable membrane) and control (bioresorbable membrane alone) treatment groups. Probing pocket depth (PPD), relative attachment level, and relative gingival margin level were measured with a computerized Florida disc probe at baseline and at 6 months follow-up. Radiographic measurements were also evaluated at baseline and at 6 months of postsurgery. Results: At 6 months, the mean reduction in PPD in test group and control group was 4.52 mm and 2.97 mm, respectively. Significantly higher clinical attachment level with a gain of 2.20 mm was found in the test group as compared to control group. In addition, statistically significant greater reduction of radiographic defect depth was observed in the test group. Conclusion: Regenerative approach using hyaloss in combination with GTR for the treatment of human infrabony defects resulted in a significant added benefit in terms of CAL gains, PPD reductions and radiographic defect fill, as well as LBG, compared to the GTR alone.

Comparing the effects of metformin or orlistat on hormone, lipid profile and ovulation status in obese women with polycystic ovary syndrome. A total of 80 women were prospectively recruited to receive either metformin (n = 40) or orlistat (n = 40). Weight, BMI, waist, serum LH, total serum testosterone and lipid profile were assessed at baseline and after 3 months. The subjects' ovulatory status was assessed after 3 months. There was no significant difference in ovulation between the two treatment groups (30% vs 15%). Treatment with either drug showed a significant decline in body weight, BMI (Body Mass Index), and waist circumference, but the degree of decline in both groups was the same. Patients who were treated with orlistat, showed a significant reduction in total testosterone and serum lipid. Women in metformin group showed a significant reduction in serum LH. Both metformin and orlistat showed a similar effect on weight loss and ovulation rates.

Biomedical treatment options for autism spectrum disorder (ASD) are extremely limited. Repetitive transcranial magnetic stimulation (rTMS) is a safe and efficacious technique when targeting specific areas of cortical dysfunction in major depressive disorder, and a similar approach could yield therapeutic benefits in ASD, if applied to relevant cortical regions. The aim of this study was to examine whether deep rTMS to bilateral dorsomedial prefrontal cortex improves social relating in ASD. 28 adults diagnosed with either autistic disorder (high-functioning) or Asperger's disorder completed a prospective, double-blind, randomized, placebo-controlled design with 2 weeks of daily weekday treatment. This involved deep rTMS to bilateral dorsomedial prefrontal cortex (5 Hz, 10-s train duration, 20-s inter-train interval) for 15 min (1500 pulses per session) using a HAUT-Coil. The sham rTMS coil was encased in the same helmet of the active deep rTMS coil, but no effective field was delivered into the brain. Assessments were conducted before, after, and one month following treatment. Participants in the active condition showed a near significant reduction in self-reported social relating symptoms from pre-treatment to one month follow-up, and a significant reduction in social relating symptoms (relative to sham participants) for both post-treatment assessments. Those in the active condition also showed a reduction in self-oriented anxiety during difficult and emotional social situations from pre-treatment to one month follow-up. There were no changes for those in the sham condition. Deep rTMS to bilateral dorsomedial prefrontal cortex yielded a reduction in social relating impairment and socially-related anxiety. Further research in this area should employ extended rTMS protocols that approximate those used in depression in an attempt to replicate and amplify the clinical response.

The aim of the present study was to examine the association between glycemic excursions before treatment and HbA1c reduction after treatment intensification with acarbose or glibenclamide in patients with type 2 diabetes (T2D). Patients receiving single or dual oral antidiabetic drug treatment with an HbA1c of 7.0-11.0 % (53-97 mmol/mol) were switched to metformin monotherapy (500 mg, t.i.d.) for 8 weeks, followed by randomization to either acarbose (100 mg, t.i.d.) or glibenclamide (5 mg, t.i.d.) as add-on treatment for 16 weeks. Glycemic excursions were assessed as mean amplitude of glycemic excursions (MAGE) with 72-h ambulatory continuous glucose monitoring. Treatment efficacy was evaluated as relative HbA1c reduction (%), calculated as (baseline HbA1c - post-treatment HbA1c)/baseline HbA1c × 100. Fifty patients (mean [±SD] age 53.5 ± 8.2 years, 48 % men, mean baseline HbA1c 8.4 ± 1.2 %) were analyzed. Baseline MAGE was positively correlated with relative HbA1c reduction from baseline in patients treated with acarbose (r = 0.421, P = 0.029) but not glibenclamide (r = 0.052, P = 0.813). Linear regression analysis revealed that the association between baseline MAGE and relative HbA1c reduction from baseline (β = 0.125, P = 0.029) in patients treated with acarbose remained significant after adjustment for several confounders (P < 0.05 for all models). In patients with T2D on metformin monotherapy, baseline MAGE was positively correlated with relative HbA1c reduction from baseline after treatment with acarbose, but not glibenclamide. These findings highlight the importance of glycemic excursions in individualized treatment for patients with T2D. © 2016 Ruijin Hospital, Shanghai JiaoTong University School of Medicine (SJTU), Chinese Society of Endocrinology and Chinese Endocrinologist Association and John Wiley & Sons Australia, Ltd.

2014-08-01

The stability of a gas-phase furfural hydrogenation catalyst (CuCr2O4 center dot CuO) was enhanced by depositing a thin Al2O3 layer using atomic layer deposition (ALD). Based on temperature-programed reduction (TPR) measurements, the reduction temperature of Cu was raised significantly, and the activation energy for furfural reduction was decreased following the ALD treatment. Thinner ALD layers yielded higher furfural hydrogenation activities. X-ray absorption fine structure (XAFS) spectroscopy studies indicated that Cu1+/Cu-0 are the active species for furfural reduction.

Low-Level Laser Therapy in the Treatment of Recurrent Aphthous Ulcers: A Systematic Review

PubMed Central

Vale, Fernando Alves; de Almeida, Fernanda Campos Souza

2015-01-01

Recurrent aphthous ulcers (RAUs) are the most common lesion found in the oral cavity. There is no definitive cure for RAUs and current treatments are aimed at minimizing symptoms. Since low-level laser therapy (LLLT) modulates inflammatory responses, and promotes pain reduction and cellular biostimulation, LLLT can be suggested as an alternative treatment for RAUs. The literature concerning the potential of LLLT in the treatment of RAUs was evaluated. A systematic literature review identified 22 publications, of which only 2 studies were adopted. The eligibility criteria consisted of randomized controlled trials (RCTs). Both RCTs achieved significant results concerning LLLT and pain-level reductions and reduced healing times. Despite the variance in irradiation conditions applied in both studies, very similar wavelengths were adopted. There is accordingly strong evidence that wavelength plays an important role in RAU treatment. Taking into account the different parameters applied by selected RCTs, it is not possible to suggest that a specific protocol should be used. However, in light of the significant results found in both studies, LLLT can be suggested as an alternative for RAU treatment. Additional RCTs should be performed in order to reach a clinical protocol and better understand the application of LLLT in RAU treatment. PMID:25879049

Follow-up data across an 18-month period are presented for 43 adults who had been randomly assigned and had responded to short-term client-centered (CC) and emotion-focused (EFT) therapies for major depression. Long-term effects of these short-term therapies were evaluated using relapse rates, number of asymptomatic or minimally symptomatic weeks, survival times across an 18-month follow-up, and group comparisons on self-report indices at 6- and 18-month follow-up among those clients who responded to the acute treatment phase. EFT treatment showed superior effects across 18 months in terms of less depressive relapse and greater number of asymptomatic or minimally symptomatic weeks, and the probability of maintaining treatment gains was significantly more likely in the EFT treatment than in the CC treatment. In addition, follow-up self-report results demonstrated significantly greater effects for EFT clients on reduction of depression and improvement of self-esteem, and there were trends in favor of EFT, in comparison with CC, on reduction of general symptom distress and interpersonal problems. Maintenance of treatment gains following an empathic relational treatment appears to be enhanced by the addition of specific experiential and gestalt-derived emotion-focused interventions. Clinical and theoretical implications of these findings are presented.

Evaluation of ultrasound-guided high-intensity focused ultrasound (HIFU) used for the first time in Germany in patients with inoperable pancreatic cancer for reduction of tumor volume and relief of tumor-associated pain. 15 patients with locally advanced inoperable pancreatic cancer and tumor-related pain symptoms were treated by HIFU (n = 6 UICC stage III, n = 9 UICC stage IV). 13 patients underwent simultaneous standard chemotherapy. Ablation was performed using the JC HIFU system (Chongqing, China HAIFU Company) with an ultrasonic device for real-time imaging. Imaging follow-up (US, CT, MRI) and clinical assessment using validated questionnaires (NRS, BPI) was performed before and up to 15 months after HIFU. Despite biliary or duodenal stents (4/15) and encasement of visceral vessels (15/15), HIFU treatment was performed successfully in all patients. Treatment time and sonication time were 111 min and 1103 s, respectively. The applied total energy was 386 768 J. After HIFU ablation, contrast-enhanced imaging showed devascularization of treated tumor regions with a significant average volume reduction of 63.8 % after 3 months. Considerable pain relief was achieved in 12 patients after HIFU (complete or partial pain reduction in 6 patients). US-guided HIFU with a suitable acoustic pathway can be used for local tumor control and relief of tumor-associated pain in patients with locally advanced pancreatic cancer. • US-guided HIFU allows an additive treatment of unresectable pancreatic cancer.• HIFU can be used for tumor volume reduction.• Using HIFU, a significant reduction of cancer-related pain was achieved.• HIFU provides clinical benefit in patients with pancreatic cancer.

Background Metoprolol treatment is well established for chronic heart failure (CHF) patients, but the central nervous system side effects are often a potential drawback. Objective To investigate the impact of metoprolol treatment on change in mental status of CHF patients with clinical psychological disorders (such as depression, anxiety, and burnout syndrome). Methods From February 2013 to April 2016, CHF patients with clinical mental disorders received metoprolol (23.75 or 47.5 mg, qd PO, dose escalated with 23.75 mg each time until target heart rate [HR] <70 bpm was achieved) at the Second Affiliated Hospital of Kunming Medical University. Mental status was assessed by means of the Hospital Anxiety and Depression Scale (HADS) and the Copenhagen Burnout Inventory (CBI) scale. The primary outcome assessed was change in mental status of patients post-metoprolol treatment and the association with reduction in HR achieved by metoprolol. Results A total of 154 patients (median age: 66.39 years; males: n=101) were divided into eight groups on the basis of their mental status. HR decreased significantly from baseline values in all the groups to <70 bpm in the 12th month, P≤0.0001. The HADS depression and CBI scores significantly increased from baseline throughout the study frame (P≤0.0001 for all groups), but a significant decrease in the HADS anxiety score was observed in patients with anxiety (P≤0.0001 for all groups). Regression analysis revealed no significant correlation in any of the groups between the HR reduction and the change in the HADS/CBI scores, except for a change in the CBI scores of CHF patients with depression (P=0.01), which was HR dependent. Conclusion Metoprolol treatment worsens the depressive and high burnout symptoms, but affords anxiolytic benefits independent of HR reduction in CHF patients with clinical mental disorders. Hence, physicians need to be vigilant while prescribing metoprolol in CHF patients who present with mental disorders. PMID:28182127

Exercise is a promising treatment for substance use disorders, yet an intention-to-treat analysis of a large, multi-site study found no reduction in stimulant use for exercise versus health education. Exercise adherence was sub-optimal; therefore, secondary post-hoc complier average causal effects (CACE) analysis was conducted to determine the potential effectiveness of adequately dosed exercise. The STimulant use Reduction Intervention using Dosed Exercise study was a randomized controlled trial comparing a 12 kcal/kg/week (KKW) exercise dose versus a health education control conducted at nine residential substance use treatment settings across the U.S. that are affiliated with the National Drug Abuse Treatment Clinical Trials Network. Participants were sedentary but medically approved for exercise, used stimulants within 30 days prior to study entry, and received a DSM-IV stimulant abuse or dependence diagnosis within the past year. A CACE analysis adjusted to include only participants with a minimum threshold of adherence (at least 8.3 KKW) and using a negative-binomial hurdle model focused on 218 participants who were 36.2% female, mean age 39.4 years ( SD =11.1), and averaged 13.0 ( SD =9.2) stimulant use days in the 30 days before residential treatment. The outcome was days of stimulant use as assessed by the self-reported TimeLine Follow Back and urine drug screen results. The CACE-adjusted analysis found a significantly lower probability of relapse to stimulant use in the exercise group versus the health education group (41.0% vs. 55.7%, p <.01) and significantly lower days of stimulant use among those who relapsed (5.0 days vs. 9.9 days, p <.01). The CACE adjustment revealed significant, positive effects for exercise. Further research is warranted to develop strategies for exercise adherence that can ensure achievement of an exercise dose sufficient to produce a significant treatment effect.

To compare the efficacy in terms of reduction in melasma area and severity index (MASI) score by more than 10 of a combination of 20% trichloro-acetic acid peel plus 5% topical magnesium ascorbyl phosphate versus 20% trichloroacetic acid peel alone in the treatment of epidermal melasma. Randomized controlled trial. Department of Dermatology, Lady Reading Hospital (LRH), Peshawar, from May 2012 to May 2013. Patients aged 18 - 65 years, with Fitzpatrick skin type III-V were divided into two equal groups having 74 patients each. Detailed history was taken and Wood's lamp examination done to rule out mixed and dermal melasma. Melasma area and severity index (MASI) score was calculated for every patient. Priming was done for all patients with tretinoin cream applied once daily at night for 2 weeks, and to use a broad spectrum sun block cream before sun exposure. Patients in group Awere subjected to combined treatment, i.e. trichloro-acetic acid peel 20% (weekly) plus magnesium ascorbyl phosphate cream (applied once daily), while patients in group B were subjected to trichloro-acetic acid peel 20% (weekly) alone. Treatment was continued for 6 weeks. After completion of treatment, MASI score was recalculated. Proportion of patients with significant MASI score reduction was compared using chi-square test with significance at p < 0.05. Male and female patients were 11 (14.9%) and 63 (85.1%), respectively in group A, whereas 13 (17.6%) and 61 (82.4%) in group B. The mean age in group Awas 30.28 ±8.08 years, and 29.36 ±6.84 years in group B. Significant MASI score reduction in group Awas seen in 60 (81.1%) patients and in group B 49 (66.2%, p= 0.040). Combination of trichloro-acetic acid peel and topical magnesium ascorbyl phosphate cream was significantly more effective than trichloro-acetic acid peel alone in treatment of melasma.

Alfalfa sprouts have been associated with numerous foodborne outbreaks. Previous studies investigated the effectiveness of aqueous ozone on bacterially contaminated seeds, yet little is known about the response of human norovirus (huNoV). This study assessed aqueous ozone for the disinfection of alfalfa seeds contaminated with huNoV and its surrogates. The inactivation of viruses without a food matrix was also investigated. Alfalfa seeds were inoculated with huNoV genogroup II, Tulane virus (TV), and murine norovirus (MNV); viruses alone or inoculated on seeds were treated in deionized water containing 6.25 ppm of aqueous ozone with agitation at 22°C for 0.5, 1, 5, 15, or 30 min. The data showed that aqueous ozone resulted in reductions of MNV and TV infectivity from 1.66 ± 1.11 to 5.60 ± 1.11 log PFU/g seeds; for all treatment times, significantly higher reductions were observed for MNV (P < 0.05). Viral genomes were relatively resistant, with a reduction of 1.50 ± 0.14 to 3.00 ± 0.14 log genomic copies/g seeds; the reduction of TV inoculated in water was similar to that of huNoV, whereas MNV had significantly greater reductions in genomic copies (P < 0.05). Similar trends were observed in ozone-treated viruses alone, with significantly higher levels of inactivation (P < 0.05), especially with reduced levels of infectivity for MNV and TV. The significant inactivation by aqueous ozone indicates that ozone may be a plausible substitute for chlorine as an alternative treatment for seeds. The behavior of TV was similar to that of huNoV, which makes it a promising surrogate for these types of scenarios.

The aim of this pilot study was to evaluate the changes in symptom severity and long-term health care cost after intensive short-term dynamic psychotherapy (ISTDP) individually tailored and administered to patients with psychotic disorders undergoing standard psychiatric care. Eleven therapists with different levels of expertise delivered an average of 13 one-hour sessions of graded ISTDP to 38 patients with psychotic disorders. Costs for health care services were compiled for a one-year period prior to the start of ISTDP (baseline) along with four one-year periods after termination. Two validated self-report scales, the Brief Symptom Inventory and the Inventory of Interpersonal Problems, were administered at intake and termination of ISTDP. Results revealed that health care cost reductions were significant for the one-year post-treatment period relative to baseline year, for both physician costs and hospital costs, and the reductions were sustained for the follow-up period of four post-treatment years. Furthermore, at treatment termination self-reported symptoms and interpersonal problems were significantly reduced. These preliminary findings suggest that this brief adjunctive psychotherapy may be beneficial and reduce costs in selected patients with psychotic disorders, and that gains are sustained in long-term follow-up.

A double-blind, randomized, parallel and active-controlled clinical study was conducted to evaluate the anti-hypertensive effect as well as the tolerability of Olive leaf extract in comparison with Captopril in patients with stage-1 hypertension. Additionally, this study also investigated the hypolipidemic effects of Olive leaf extract in such patients. It consisted of a run-in period of 4 weeks continued subsequently by an 8-week treatment period. Olive (Olea europaea L.) leaf extract (EFLA(®)943) was given orally at the dose of 500 mg twice daily in a flat-dose manner throughout the 8 weeks. Captopril was given at the dosage regimen of 12.5 mg twice daily at start. After 2 weeks, if necessary, the dose of Captopril would be titrated to 25 mg twice daily, based on subject's response to treatment. The primary efficacy endpoint was reduction in systolic blood pressure (SBP) from baseline to week-8 of treatment. The secondary efficacy endpoints were SBP as well as diastolic blood pressure (DBP) changes at every time-point evaluation and lipid profile improvement. Evaluation of BP was performed every week for 8 weeks of treatment; while of lipid profile at a 4-week interval. Mean SBP at baseline was 149.3±5.58 mmHg in Olive group and 148.4±5.56 mmHg in Captopril group; and mean DBPs were 93.9±4.51 and 93.8±4.88 mmHg, respectively. After 8 weeks of treatment, both groups experienced a significant reduction of SBP as well as DBP from baseline; while such reductions were not significantly different between groups. Means of SBP reduction from baseline to the end of study were -11.5±8.5 and -13.7±7.6 mmHg in Olive and Captopril groups, respectively; and those of DBP were -4.8±5.5 and -6.4±5.2 mmHg, respectively. A significant reduction of triglyceride level was observed in Olive group, but not in Captopril group. In conclusion, Olive (Olea europaea) leaf extract, at the dosage regimen of 500 mg twice daily, was similarly effective in lowering systolic and diastolic blood pressures in subjects with stage-1 hypertension as Captopril, given at its effective dose of 12.5-25 mg twice daily.

The objective of this subgroup analysis is to investigate the effectiveness of liraglutide in people with type 2 diabetes (T2D) treated within the primary care physician (PCP) and specialist care settings. EVIDENCE is a prospective, observational study of 3152 adults with T2D recently starting or about to start liraglutide treatment in France. We followed patients in the PCP and specialist settings for 2 years to evaluate the effectiveness of liraglutide in glycemic control and body weight reduction. Furthermore, we evaluated the changes in combined antihyperglycemic treatments, the reasons for prescribing liraglutide, patient satisfaction, and safety of liraglutide in these two treatment settings. After 2 years of follow-up, 477 out of 1209 (39.0%) of PCP and 297 out of 1398 (21.2%) of specialist-treated patients still used liraglutide and maintained the glycated hemoglobin (HbA 1c ) target of <7.0%. Significant reductions from baseline were observed in both PCP- and specialist-treated cohorts in mean HbA 1c (-1.22% and -0.8%, respectively), fasting plasma glucose (FPG) concentration (-39 and -23 mg/dL), body weight (-4.4 and -3.8 kg), and body mass index (BMI) (-1.5 and -1.4 kg/m 2 ), all p < 0.0001. Reductions in HbA 1c and FPG were significantly greater among PCP- compared with specialist-treated patients, p < 0.0001 for both. Patient treatment satisfaction was also significantly increased in both cohorts. Reported gastrointestinal adverse events were less frequent among PCP-treated patients compared with specialist-treated patients (4.5% vs. 16.1%). Despite differences in demography and clinical characteristics of patients treated for T2D in PCP and specialty care, greater reduction in HbA 1c and increased glycemic control durability were observed with liraglutide in primary care, compared with specialist care. These data suggest that liraglutide treatment could benefit patients in primary care by delaying the need for further treatment intensification. ClinicalTrials.gov identifier, NCT01226966.

Salivary hypofunction and xerostomia: diagnosis and treatment.

PubMed

Atkinson, Jane C; Grisius, Margaret; Massey, Ward

2005-04-01

Salivary gland hypofunction and complaints of xerostomia are common in elderly patients, irrespective of their living situation. Medication use is frequently related to dry mouth symptoms and reductions in salivary flow rates. Patients with reduced salivary flow are at increased risk for caries, oral fungal infections, swallowing problems, and diminished or altered taste. Oral health care providers should institute aggressive preventive measures and recommend palliative care for patients with significant reduction in salivary gland function. The systemic agents pilocarpine and cevimeline may help selected patients. Selective use of fluoride-releasing restorative materials and conservative treatment plans are recommended for this patient group.

Visual acuity and astigmatism in periocular infantile hemangiomas treated with oral beta-blocker versus intralesional corticosteroid injection.

2016-02-01

Periocular infantile hemangiomas (PIH) can induce anisometropic astigmatism, a risk factor for amblyopia. Oral beta-blocker therapy has largely supplanted systemic or intralesional corticosteroids. The purpose of this study was to evaluate the effect and time course of these treatment modalities on visual acuity and induced astigmatism. The medical records of patients with PIH treated with oral propanolol between November 2008 and July 2013 were retrospectively reviewed for data on visual acuity and astigmatism. Patients with incomplete pre- and post-treatment ophthalmic examinations were excluded. Results were compared to those of a similar cohort treated with intralesional corticosteroid injection. Mean astigmatism in affected eyes was 1.90 D before propranolol and 1.00 D after; patients showed a monophasic reduction in astigmatism over 12 months. By comparison, patients treated with corticosteroid injection showed a biphasic response, with an immediate steep decrease followed by a slow monophasic decline, paralleling propranolol-treated patients. Oral propranolol treatment caused a 47% reduction in mean induced astigmatism, less than the 63% reduction reported for the cohort treated with corticosteroid. No patient had visual acuity in the affected eye more than 1 standard devation below the age-matched norm, and none experienced significant side effects when treated with oral propranolol. In this patient cohort oral beta-blocker was well-tolerated. Treatment was therefore often initiated prior to the induction of significant astigmatism, with treatment effects comparable to steroid treatment. Visual outcomes were good. Early treatment may minimize the potential effect of astigmatism on postnatal visual development. Copyright © 2016 American Association for Pediatric Ophthalmology and Strabismus.

Purpose To determine whether dual-input perfusion computed tomography (CT) can predict therapeutic response and prognosis in patients who underwent chemotherapy for non-small cell lung cancer (NSCLC). Materials and Methods The institutional review board approved this study and informed consent was obtained. Sixty-six patients with stage III or IV NSCLC (42 men, 24 women; mean age, 63.4 years) who underwent chemotherapy were enrolled. Patients were separated into three groups: those who received chemotherapy with bevacizumab (BV) (n = 20), those who received two-agent platinum-based therapy without BV (n = 25), and those who received other non-BV treatment (n = 21). Before treatment, pulmonary artery perfusion (PAP) and bronchial artery perfusion (BAP) of the tumors were calculated. Predictors of tumor reduction after two courses of chemotherapy and prognosis were identified by using univariate and multivariate analyses. Covariates included were age, sex, patient's performance status, baseline maximum diameter of the tumor, clinical stage, pretreatment PAP, and pretreatment BAP. For multivariate analyses, multiple linear regression analysis for tumor reduction rate and Cox proportional hazards model for prognosis were performed, respectively. Results Pretreatment BAP was independently correlated with tumor reduction rate after two courses of chemotherapy in the BV treatment group (P = .006). Pretreatment BAP was significantly associated with a highly cumulative risk of death (P = .006) and disease progression after chemotherapy (P = .015) in the BV treatment group. Pretreatment PAP and clinical parameters were not significant predictors of therapeutic effect or prognosis in three treatment groups. Conclusion Pretreatment BAP derived from dual-input perfusion CT seems to be a promising tool to help predict responses to chemotherapy with BV in patients with NSCLC. © RSNA, 2017.

Background Comorbid substance use disorders (SUD) are associated with increased illness severity and functional impairment among adolescents with bipolar disorder (BD). Previous psychosocial treatment studies have excluded adolescents with both BD and SUD. Studies suggest that integrated interventions are optimal for adults with BD and SUD. Methods We modified family-focused treatment for adolescents with BD (FFT-A) in order to explicitly target comorbid SUD (FFT-SUD). Ten adolescents with BD who had both SUD and an exacerbation of manic, depressed, or mixed symptoms within the last 3 months were enrolled. FFT-SUD was offered as an adjunct to pharmacotherapy, with a target of 21 sessions over 12 months of treatment. The FFT-SUD manual was iteratively modified to integrate a concurrent focus on SUD. Results Six subjects completed a mid-treatment 6-month assessment (after a mean of 16 sessions was completed). Of the 10 subjects, 3 dropped out early ( after ≤ 1 session); in the case of each of these subjects, the participating parent had active SUD. No other subjects in the study had a parent with active SUD. Preliminary findings suggested significant reductions in manic symptoms and depressive symptoms and improved global functioning. Reduction in cannabis use was modest and did not reach significance. Limitations Limitations included a small sample, open treatment, concurrent medications, and no control group. Conclusions These preliminary findings suggest that FFT-SUD is a feasible intervention, particularly for youth without parental SUD. FFT-SUD may be effective in treating mood symptoms, particularly depression, despite modest reductions in substance use. Integrating motivation enhancing strategies may augment the effect of this intervention on substance use. Additional strategies, such as targeting parental substance use, may prevent early attrition.

An innovative liposomal formulation of meglumine antimoniate (LMA) was recently reported to promote both long-term parasite suppression and reduction of infectivity to sand flies in dogs with visceral leishmaniasis. However, 5 months after treatment, parasites were still found in the bone marrow of all treated dogs. In order to improve treatment with LMA, the present study aimed to evaluate its efficacy in combination with allopurinol. Mongrel dogs naturally infected with Leishmania infantum were treated with six doses of LMA (6.5 mg Sb/kg of body weight/dose) given at 4-day intervals, plus allopurinol (20 mg/kg/24 h per os) for 140 days. Comparison was made with groups treated with LMA, allopurinol, empty liposomes plus allopurinol, empty liposomes, and saline. Dogs remained without treatment from day 140 to 200 after the start of treatment. The drug combination promoted both clinical improvement of dogs and significant reduction in the parasitic load in bone marrow and spleen on days 140 and 200 compared to these parameters in the pretreatment period. This is in contrast with the other protocols, which did not result in significant reduction of the bone marrow parasite load on day 200. Strikingly, the combined treatment, in contrast to the other regimens, induced negative quantitative PCR (qPCR) results in the liver of 100% of the dogs. Both xenodiagnosis and skin parasite determination by qPCR indicated that the drug combination was effective in blocking the transmission of skin parasites to sand flies. Based on all of the parasitological tests performed on day 200, 50% of the animals that received the combined treatment were considered cured. PMID:22411610

This study investigated the effect of lemongrass essential oil (LGEO) on the infectivity and viral replication of norovirus. Murine norovirus 1 (MNV-1), a surrogate of human norovirus, was preincubated with LGEO and then used to infect RAW 264.7 cells in a plaque reduction assay. LGEO exhibited a significant reduction in MNV-1 plaque formation in both time- and dose-dependent manners. The quantification of viral genome by quantitative real-time PCR showed similar results in line with those of the plaque reduction assay. It was revealed that citral, a single compound in LGEO, showed dramatic reduction in MNV-1 infectivity (-73.09% when using a treatment of 0.02%, v/v). The inhibitory activity of LGEO on viral replication was further investigated in HG23 cells that harbored a human norovirus replicon. LGEO treatment significantly reduced viral replication in HG23 cells, which suggests that LGEO may have dual inhibitory activities that inactivate viral coat proteins required for viral infection and suppress norovirus genome replication in host cells. In animal experiments, oral administration of murine norovirus preincubated with LGEO significantly suppressed virus infectivity in vivo. Collectively, these results suggest that LGEO, in particular the LGEO component citral, inactivates the norovirus and its subsequent replication in host cells. Thus, LGEO shows promise as a method of inhibiting norovirus within the food industry.

In aesthetic medicine, the most promising techniques for noninvasive body sculpturing purposes are based on ultrasound-induced fat cavitation. Liporeductive ultrasound devices afford clinically relevant subcutaneous fat pad reduction without significant adverse reactions. This study aims at evaluating the histological and ultrastructural changes induced by ultrasound cavitation on the different cell components of human skin. Control and ultrasound-treated ex vivo abdominal full-thickness skin samples and skin biopsies from patients pretreated with or without ultrasound cavitation were studied histologically, morphometrically, and ultrastructurally to evaluate possible changes in adipocyte size and morphology. Adipocyte apoptosis and triglyceride release were also assayed. Clinical evaluation of the effects of 4 weekly ultrasound vs sham treatments was performed by plicometry. Compared with the sham-treated control samples, ultrasound cavitation induced a statistically significant reduction in the size of the adipocytes (P < 0.001), the appearance of micropores and triglyceride leakage and release in the conditioned medium (P < 0.05 at 15 min), or adipose tissue interstitium, without appreciable changes in microvascular, stromal, and epidermal components and in the number of apoptotic adipocytes. Clinically, the ultrasound treatment caused a significant reduction of abdominal fat. This study further strengthens the current notion that noninvasive transcutaneous ultrasound cavitation is a promising and safe technology for localized reduction of fat and provides experimental evidence for its specific mechanism of action on the adipocytes.

Impact of methamphetamine precursor chemical legislation, a suppression policy, on the demand for drug treatment.

Cunningham, James K; Liu, Lon-Mu

Research is needed to help treatment programs plan for the impacts of drug suppression efforts. Studies to date indicate that heroin suppression may increase treatment demand. This study examines whether treatment demand was impacted by a major US methamphetamine suppression policy -- legislation regulating precursor chemicals. The precursors ephedrine and pseudoephedrine, in forms used by large-scale methamphetamine producers, were regulated in August 1995 and October 1997, respectively. ARIMA-intervention time-series analysis was used to examine the impact of each precursor's regulation on monthly voluntary methamphetamine treatment admissions (a measure of treatment demand), including first-time admissions and re-admissions, in California (1992-2004). Cocaine, heroin, and alcohol treatment admissions were used as quasi-control series. The 1995 regulation of ephedrine was found to be associated with a significant reduction in methamphetamine treatment admissions that lasted approximately 2 years. The 1997 regulation of pseudoephedrine was associated with a significant reduction that lasted approximately 4 years. First-time admissions declined more than re-admissions. Cocaine, heroin, and alcohol admissions were generally unaffected. While heroin suppression may be associated with increased treatment demand as suggested by research to date, this study indicates that methamphetamine precursor regulation was associated with decreases in treatment demand. A possible explanation is that, during times of suppression, heroin users may seek treatment to obtain substitute drugs (e.g., methadone), while methamphetamine users have no comparable incentive. Methamphetamine suppression may particularly impact treatment demand among newer users, as indicated by larger declines in first-time admissions.

In our tests, we artificially infected liquid whole egg samples with Salmonella enteritidis, Listeria monocytogenes, and Staphylococcus aureus bacteria, and then treated the samples in "Food Lab900" high hydrostatic pressure (HHP) instrument for 3-17 min at 200-400 MPa. Subsequently, the change of the viable cell count of the specific bacteria has been tested. In addition to the samples infected with various bacteria, non-infected samples were also treated in each test and the change in viable cell count, colour and viscosity of the samples upon the effect of the treatment. In summary, it can be concluded that in each test of our investigations, the viable cell count of S. enteritidis critical for egg products is reduced significantly, while the reduction of the total viable cell count was around two magnitudes. Additionally, based on our results, microbial destruction, reduction of enthalpy (denaturation of egg white) caused by the treatment at HPP, and colour change are primarily affected by the pressure level, while the changes in rheological properties are also significantly affected by the duration of high pressure treatment (p<0.05).

This study investigated effects of high pressure (HP) treatment of pork meat at 150 or 300 MPa for 5 min before manufacturing sausages on the reduction of phosphate levels and compared to sausages manufactured with untreated pork meat (control sausages). Improvement in perceived saltiness, juiciness and overall flavour was observed in sausages manufactured using HP-treated meat at 150 MPa and 0% phosphate, compared to control sausages. Sausages manufactured using meat HP-treated at 150 MPa and 0.25% phosphate (P<0.05) improved hardness of sausages. HP-treated meat at 300 MPa and 0% phosphate decreased juiciness and adhesiveness, while at 0.25% phosphate, adversely affected emulsion stability and sensory attributes. HP treatment did not affect significantly the lightness of the sausages; however, elimination of phosphate reduced (P<0.05) the yellowness, while HP treatment at 150 MPa with 0.25 or 0.5% phosphate increased (P<0.05) redness. HP reatment at 150 MPa has potential for reducing phosphate levels in sausages without significant changes in their functionality and improved acceptability. © 2013.

Measuring the benefit of orthophosphate treatment on lead in drinking water.

PubMed

Cardew, P T

2009-03-01

Many water companies are adding low concentrations of orthophosphate to the water supply in order to reduce lead concentrations in drinking water produced from corrosion of lead service pipes. Despite the erratic nature of lead concentrations measured at customer properties it has been possible to quantify the impact of treatment on lead concentrations and thereby quantify the effectiveness of treatment at both a regional and zonal level. This showed that the treatment policy has delivered more than 90 per cent reduction in lead concentrations, and was largely in accordance with theory. Across the region, lead performance and the reduction in lead performance show significant variation. A large part of this variation can be accounted for by variations in the proportion of leaded properties supplied through lead service pipes. Analysis showed that the proportion of particulate lead has also reduced significantly over the last decade. This is attributed to improved mechanical robustness of the corrosion layer caused by changes in its physical structure. This appears to be a very slow process with a natural time-scale of years.

1981-01-01

Recently a new chemical wastewater treatment process based upon precipitation of proteins by sodium lignosulphonate under acid conditions is used to purify the wastewater from slaughterhouses and poultry processing plants. In order to determine the reduction of indicator organisms due to this treatment process, influent and effluent samples from two of such plants (plant A in a pig slaughterhouse and plant B in a poultry processing plant) were examined. The results demonstrated that the pH used in the process, has a considerable influence on the reduction of the indicator organisms. On the first sampling day in plant A the initial working-pH was 4 and the corresponding reduction of the different microorganisms varied from 0.7 to 1.5 log. According to the decrease of the pH to 2.3, the reduction increased to a minimum of at least 1.9 and a maximum of at least 4.5 log. In the other samples from this plant (working-pH 2.4) the elimination ranged from 1.8 to 4.0 log. In plant B, the removal of the indicator organisms brought about by a working-pH of 3.0 ranged from 2.1 to 3.1 log. The results showed that in comparison with the biological treatment processes this chemical wastewater treatment process realized a significant greater removal of indicator organisms.

Contribution of Early Detection and Adjuvant Treatments to Breast Cancer Mortality Reduction in Catalonia, Spain

Vilaprinyo, Ester; Puig, Teresa; Rue, Montserrat

2012-01-01

Background Reductions in breast cancer (BC) mortality in Western countries have been attributed to the use of screening mammography and adjuvant treatments. The goal of this work was to analyze the contributions of both interventions to the decrease in BC mortality between 1975 and 2008 in Catalonia. Methodology/Principal Findings A stochastic model was used to quantify the contribution of each intervention. Age standardized BC mortality rates for calendar years 1975–2008 were estimated in four hypothetical scenarios: 1) Only screening, 2) Only adjuvant treatment, 3) Both interventions, and 4) No intervention. For the 30–69 age group, observed Catalan BC mortality rates per 100,000 women-year rose from 29.4 in 1975 to 38.3 in 1993, and afterwards continuously decreased to 23.2 in 2008. If neither of the two interventions had been used, in 2008 the estimated BC mortality would have been 43.5, which, compared to the observed BC mortality rate, indicates a 46.7% reduction. In 2008 the reduction attributable to screening was 20.4%, to adjuvant treatments was 15.8% and to both interventions 34.1%. Conclusions/Significance Screening and adjuvant treatments similarly contributed to reducing BC mortality in Catalonia. Mathematical models have been useful to assess the impact of interventions addressed to reduce BC mortality that occurred over nearly the same periods. PMID:22272292

This study was driven by the need to understand the mechanisms underlying Lidcombe Program treatment efficacy. The aim of the present study was to extend existing data exploring whether stuttering reductions observed when children successfully treated with the Lidcombe Program are associated with restricted language development. Audio recordings of 10-min parent-child conversations at home were transcribed verbatim for 11 pre-school-age children with various stuttering severities. Language samples from three assessments-pre-treatment, 9 and 18 months after beginning treatment-were analysed using SALT software for lexical diversity, utterance length and sentence complexity. At 18 months posttreatment commencement, the children had attained and maintained statistically significant stuttering reductions. During that period, there was no evidence that Lidcombe Program treatment was associated with restricted language development. The continued search for the mechanisms underlying this successful treatment needs to focus on other domains.

This study evaluated the efficacy of rational-emotive imagery as a component of rational-emotive therapy in reduction of college students' test anxiety. 11 volunteers met for 6 1-hr. group treatment sessions over a 3-wk. period. After 2 initial treatment sessions subjects were randomly assigned to groups given either rational-emotive therapy with rational-emotive imagery or rational-emotive therapy without imagery. Contrary to predictions, improvement between groups on self-report and performance measures was nonsignificant. Failure to obtain differences was attributed to similarities in content of treatment sessions and short treatment time. Combined groups reported significant improvement on all dependent measures. Although the study did not yield the predicted benefits of the imagery, results lend further support to the efficacy of rational-emotive therapy procedures in the reduction of test anxiety.

In addition to lipid-lowering and insulin-sensitizing actions, statins (HMG-CoA reductase inhibitors) and metformin may have pleiotropic effects. To study the effect of simvastatin and metformin on insulin sensitivity and inflammatory markers. Forty-one subjects with body mass index (BMI) 25-39.9 kg/m(2) and impaired glucose tolerance were randomized to receive simvastatin or metformin for 16 weeks. Blood samples were obtained for measurement of metabolic and inflammatory parameters before and after each treatment. As expected, when compared with simvastatin, metformin therapy resulted in significant reductions in mean BMI, fasting plasma glucose, and homeostasis model assessment-insulin resistance (HOMA-IR), whereas simvastatin treatment resulted in significantly reduced total cholesterol, low-density lipoprotein-cholesterol (LDL-C), and apolipoprotein B levels. Independently of the medication used, significant decreases in C-reactive protein (CRP) and interleukin (IL)-6 were detected from baseline to treatment end. CRP showed a mean reduction of 0.12 +/- 0.04 mg/dL (p = 0.002) over the 16-week intervention period and IL-6 a mean reduction was 0.35 +/- 0.17 pg/mL (p = 0.046). No change was observed in the tumor necrosis factor-alpha levels. Baseline values of CRP and IL-6 and their percentage declines were correlated (r = 0.71 and r = 0.67, respectively; p < 0.001). In simvastatin recipients, no correlation was detected between reductions in CRP or IL-6 and lipids, whereas in metformin recipients, reductions in inflammatory markers were not correlated to BMI and HOMA-IR. Our findings suggest that both metformin and simvastatin have similar beneficial effects on low-grade inflammation, in addition to their classical effects on glucose and lipid metabolism. Moreover, they confirm the importance of treating at-risk individuals even before the precipitation of overt diabetes mellitus or full-blown metabolic syndrome.

A stepped care approach involves patients first receiving low-intensity treatment followed by higher intensity treatment. This two-step randomized controlled trial investigated the efficacy of a sequential stepped care approach for the psychological treatment of binge-eating disorder (BED). In the first step, all participants with BED (n = 135) received unguided self-help (USH) based on a cognitive-behavioral therapy model. In the second step, participants who remained in the trial were randomized either to 16 weeks of group psychodynamic-interpersonal psychotherapy (GPIP) (n = 39) or to a no-treatment control condition (n = 46). Outcomes were assessed for USH in step 1, and then for step 2 up to 6-months post-treatment using multilevel regression slope discontinuity models. In the first step, USH resulted in large and statistically significant reductions in the frequency of binge eating. Statistically significant moderate to large reductions in eating disorder cognitions were also noted. In the second step, there was no difference in change in frequency of binge eating between GPIP and the control condition. Compared with controls, GPIP resulted in significant and large improvement in attachment avoidance and interpersonal problems. The findings indicated that a second step of a stepped care approach did not significantly reduce binge-eating symptoms beyond the effects of USH alone. The study provided some evidence for the second step potentially to reduce factors known to maintain binge eating in the long run, such as attachment avoidance and interpersonal problems.

The choice of appropriate treatment of discogenic low back pain (DLBP) frequently is difficult. This study sought to identify the clinical efficacy of percutaneous endoscopic lumbar annuloplasty and nucleoplasty (PELAN) to treat patients with DLBP and to investigate prognostic clinical or radiologic variables. Eighty-nine patients with a diagnosis of DLBP who underwent PELAN were included. Numeric Rating Scale (NRS) for back pain, Oswestry Disability Index % (ODI%), and modified Macnab criteria were measured at short-term (3-4 weeks) and long-term follow-up period (at least 12 months) to investigate clinical efficacy of PELAN. The subjects were defined as successful group in case of 50% or more reduction of NRS, 40% or more reduction of ODI%, and good or excellent response of Macnab criteria. Clinical and radiologic variables were compared between successful and unsuccessful outcomes group to determine prognostic variables. NRS and ODI% were significantly reduced at short- and long-term follow-up after PELAN. Sixty-two (69.7%) and 68 (76.4%) obtained successful NRS reduction and 59 (66.3%) and 68 (76.4%) accomplished successful ODI% reduction at short-term and long-term follow-up, respectively. Successful Mcnab response was found in 61% at short term and 65.2% at long term. Pain during waist flexion among clinical variables was significantly related to good clinical outcomes and Modic change among radiologic variables was significantly related to poor clinical outcomes. PELAN provided favorable outcomes in patients with DLBP who were refractory to conservative treatments. Flexion pain was good prognostic, and Modic change was a poor prognostic variable.

To examine the relationship of negative emotions with suicidal ideation during 12 weeks of Problem Adaptation Therapy (PATH) versus Supportive Therapy of Cognitively Impaired Older Adults (ST-CI), hypothesizing that improved negative emotions are associated with reduced suicidal ideation, PATH improves negative emotions more than ST-CI, and improved negative emotions, rather than other depression symptoms, predict reduction in suicidal ideation. In a randomized controlled trial of two home-delivered psychosocial interventions, 74 older participants (65-95 years old) with major depressive disorder and cognitive impairment were recruited in collaboration with community agencies. The sample reported less intense feelings than suicidal intention. Interventions and assessments were conducted in participants' homes. PATH focuses on improving emotion regulation, whereas ST-CI focuses on nonspecific therapeutic factors, such as understanding and empathy. Improved negative emotions were measured as improvement in Montgomery Asberg's Depression Rating Scales' (MADRS) observer ratings of sadness, anxiety, guilt, hopelessness, and anhedonia. Suicidal ideation was assessed with the MADRS Suicide Item. MADRS Negative Emotions scores were significantly associated with suicidal ideation during the course of treatment (F [1,165]  = 12.73, p = 0.0005). PATH participants had significantly greater improvement in MADRS emotions than ST-CI participants (treatment group by time: F [1,63.2]  = 7.02, p = 0.0102). Finally, improved negative emotions, between lagged and follow-up interview, significantly predicted reduction in suicidal ideation at follow-up interview (F [1, 96]  = 9.95, p = 0.0022). Findings thatimprovement in negative emotions mediates reduction in suicidal ideation may guide the development of psychosocial interventions for reduction of suicidal ideation (clinicaltrials.gov; NCT00368940).

Design RCT of two home-delivered psychosocial interventions. Setting Weill-Cornell Institute of Geriatric Psychiatry; interventions and assessments were conducted at participants’ home. Participants 74 older participants (65–95 years old) with MDD and cognitive impairment were recruited in collaboration with community agencies.

The aim of this study was to compare the midterm clinical and radiological outcomes of the Salter osteotomy (SO) and Tonnis lateral acetabuloplasty (TLA) with concomitant open reduction for the treatment of developmental dysplasia of the hip. Twenty-five hips of 20 patients who underwent SO with open reduction and 26 hips of 23 patients who underwent TLA with open reduction were evaluated retrospectively. The average age of the patients at the time of the operation was 35.6 months in the SO and 36.6 months in the TLA group, without a statistically significant difference (P=0.836). The average follow-up times in the SO and TLA groups were 59.9 and 54.8 months, respectively (P=0.397). Preoperative (40.6° in the SO vs. 42.2° in the TLA, P=0.451) and last follow-up acetabular index (12° in the SO vs. 14° in the TLA, P=0.227) and center-edge angle measurements (30° in the SO vs. 26° in the TLA, P=0.069) did not show a statistically significant difference between the SO and TLA groups; however, early postoperative acetabular index improvement was better in the TLA group than in the SO group (21.2° in the SO vs. 17.2° in the TLA, P=0.014). According to the Severin grading system, both groups showed a similar number of good outcomes without a statistically significant difference (P=0.936). Clinical assessment on the basis of McKay's criteria showed similar good and excellent outcomes (P=0.936). Both osteotomy techniques showed similar satisfactory outcomes for the treatment of DDH in patients older than 18 months of age.

Effects of Carbon Addition on Iron and Phosphorus in a Highly Weathered Tropical Soil

In the highly weathered iron (Fe)-rich soils of wet tropical forests, Fe may play a key role in controlling ecosystem processes because of its interactions with carbon (C) and phosphorus (P). The high NPP typical of tropical forests contributes significantly to the global C cycle. In Fe-rich tropical soils, NPP is thought to be limited by P. The periodic reducing conditions that occur in upland tropical soils may be associated with pulses of increased P availability because of the release of Fe-bound P during iron reduction. While little is known about the factors controlling Fe reduction in soils, it is likely that C availability plays a role. Typically, only simple C sources like acetate or glucose have been used to examine this limitation. However, the source of much of the C in nature is the complex mixture of organic compounds leached from leaves and litter. To investigate the linkages between Fe, C, and P, we compared the effects adding either acetate (200 mg C/L) or leaf leachate in low (50-100 mg C/L) or high (150-200 mg C/L) concentrations to incubated soils from a tropical rain forest in Puerto Rico under ambient atmospheric conditions. We measured pools of iron and phosphorus as well as pH at four time points over a month. Both Fe(II) and pH exhibited significant treatment effects, but not until the last sampling date. At this time, the Fe(II) concentration could explain 49% of the variability in soil pH. The pH was significantly higher in the acetate treatments than both the leaf leachate treatments. While Fe(II) concentration was significantly higher in the acetate treatment than the control and low leaf leachate treatment, there was no difference compared to the high leaf leachate treatment After one month microbial biomass P had increased significantly while the NaOH extractable organic P had decreased significantly. These changes suggest the rapid microbial uptake of P liberated from Fe. In conclusion, microbes appear to utilize more complex C in leaf leachate at a similar rate as acetate to promote Fe reduction. The simultaneous immobilization of P by microbes during the incubation suggests that periodic reducing conditions in the field may be associated with enhanced microbial activity and carbon cycling in these highly productive ecosystems.

Hot water treatment of beef carcass surfaces for reduction of Escherichia coli O157:H7, Salmonella typhimurium, and various indicator organisms was studied using a model carcass spray cabinet. Paired hot carcass surface regions with different external fat characteristics (inside round, outside round, brisket, flank, and clod) were removed from carcasses immediately after the slaughter and dressing process. All cuts were inoculated with bovine feces containing 10(6)/g each of rifampicin-resistant E. coli O157:H7 and S. typhimurium, or with uninoculated bovine feces. Surfaces then were exposed to a carcass water wash or a water wash followed by hot water spray (95 degrees C). Counts of rifampicin-resistant Salmonella and E. coli or aerobic plate count (APC) and coliform counts were conducted before and after each treatment. All treatments significantly reduced levels of pathogens from the initial inoculation level of 5.0 log(10) CFU/cm2. Treatments including hot water sprays provided mean reductions of initial counts for E. coli O157:H7 and S. typhimurium of 3.7 and 3.8 log, APC reductions of 2.9 log, and coliform and thermotolerant coliform count reductions of 3.3 log. The efficacy of hot water treatments was affected by the carcass surface region, but not by delaying the treatment (30 min) after contaminating the surface. Verification of efficacy of hot water interventions used as critical control points in a hazard analysis critical control point (HACCP) system may be possible using coliform counts.

The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting injection (RLAI) (n=1345) or a new oral antipsychotic (AP) (n=277; 35.7% and 36.5% on risperidone and olanzapine, respectively) in Spain. Hospitalization prior to therapy was assessed by a retrospective chart review. At 24 months, treatment retention (81.8% for RLAI versus 63.4% for oral APs, p<0.0001) and reduction in Clinical Global Impression Severity scores (-1.14 for RLAI versus -0.94 for APs, p=0.0165) were significantly higher with RLAI. Compared to the pre-switch period, RLAI patients had greater reductions in the number (reduction of 0.37 stays per patient versus 0.2, p<0.05) and days (18.74 versus 13.02, p<0.01) of hospitalizations at 24 months than oral AP patients. This 2 year, prospective, observational study showed that, compared to oral antipsychotics, RLAI was associated with better treatment retention, greater improvement in clinical symptoms and functioning, and greater reduction in hospital stays and days in hospital in patients with schizophrenia. Improved treatment adherence, increased efficacy and reduced hospitalization with RLAI offer the opportunity of substantial therapeutic improvement in schizophrenia.

Clindamycin phosphate (CDP), benzoyl peroxide (BPO) and salicylic acid (SA) are known to be effective acne therapy agents depending on their anti-inflammatory and comedolytic properties. The purpose of this study was to investigate the efficacy and tolerability of the addition of SA treatment to CDP and BPO (SA and CDP + BPO) and compare it with CDP + BPO in patients with mild to moderate facial acne vulgaris. Forty-nine patients were enrolled in a 12 week prospective, single-blind, randomized, comparative clinical study. Efficacy was assessed by lesion counts, global improvement, quality of life index and measurements of skin barrier functions. Local side effects were also evaluated. Both combinations were effective in reducing total lesion (TL), inflammatory lesion (IL) and non-inflammatory lesion (NIL) counts. There were statistically significant differences between treatment groups for reductions in NIL counts beyond 2 weeks, IL counts and TL counts throughout the all study weeks, and global improvement scores evaluated by patients and investigator at the end of the study in favor of SA and CDP + BPO treatment when compared to CDP + BPO treatment. Both combinations significantly decreased stratum corneum hydration, although skin sebum values decreased with SA and CDP + BPO treatment. These combinations were also well tolerated except significantly higher frequency of mild to moderate transient dryness in patients applied SA and CDP + BPO. The addition of SA to CDP + BPO treatment demonstrated significantly better and faster results in terms of reductions in acne lesion counts and well tolerated except for higher frequency of mild to moderate transient dryness. © 2011 Japanese Dermatological Association.

Aim Peripartum cardiomyopathy (PPCM) is a rare cause of dilated cardiomyopathy responsible for heart failure toward the end of pregnancy, which can lead to chronic heart failure in 50% of cases. In this short report, we assessed the benefit of cardiac resynchronization in patients with PPCM and chronic systolic dysfunction despite optimal medical treatment. For the last 10 years, we managed eight patients diagnosed with PPCM. Two of them presented severe systolic dysfunction, and medical treatment resulted in limited improvement from 10% to 25% and from 25% to 28% despite optimal treatment for 9 and 6 years, respectively. These two patients were porposed to receive an implantatable cardioverter defibrillator (ICD) and cardiac resynchronization therapy (CRT). Six months after ICD-CRT treatment, we observed a significant improvement in systolic function from 25% to 45% and 28% to 50%, respectively, and positive remodelling with reduction of left ventricular end-diastolic volume from 216 to 144 mL and from 354 to 105 mL, which represent a 34% and a 70% reduction, respectively. Physicians in charge of patients with PPCM should offer the opportunity of CRT for patients whose cardiac function has not significantly improved under standard medical treatment.

This study assessed the effectiveness of a biorational control approach using 2% hydramethylnon gel bait on German cockroaches, Blattella germanica (L.) in some residential and hospital buildings in South Western Iran. In total, three buildings consisting of 150 apartment units and 101 hospital units were monitored weekly via sticky trap for German cockroach infestations over a period of eight months. These infested units were randomly subjected to intervention and control treatments. Pamphlets and posters were provided and lectures were given to support the educational programmes as a tactic of the biorational system. Survey on cockroach index for intervention units showed 67-94% recovery to achieve clean level of infestation for intervention units of the residential buildings and 83% for the hospital. Mean percentage reductions for treatment groups throughout the 15-week treatment period were 76.8% for the residential buildings and 88.1% for the hospital, showing significant differences compared to the control groups. Linear regression of infestation rates were recorded weekly after treatment and their negative slope for treatment groups substantiated significant reductions for interventions. The results of this study showed that biorational control method, using gel bait, educational programmes and sanitation, is an effective way to manage German cockroach infestation.

Significant microbial reductive dechlorination of [1,2 14C] cis-dichloroethene (DCE) was observed in anoxic microcosms prepared with unamended, fractured rock aquifer materials, which were colonized in situ at multiple depths in two boreholes at the Naval Air Warfare Center (NAWC) in West Trenton, New Jersey. The lack of significant reductive dechlorination in corresponding water-only treatments indicated that chlororespiration activity in unamended, fractured rock treatments was primarily associated with colonized core material. In these unamended fractured rock microcosms, activity was highest in the shallow zones and generally decreased with increasing depth. Electron-donor amendment (biostimulation) enhanced chlororespiration in some but not all treatments. In contrast, combining electron-donor amendment with KB1 amendment (bioaugmentation) enhanced chlororespiration in all treatments and substantially reduced the variability in chlororespiration activity both within and between treatments. These results indicate (1) that a potential for chlororespiration-based bioremediation exists at NAWC Trenton but is limited under nonengineered conditions, (2) that the limitation on chlororespiration activity is not entirely due to electron-donor availability, and (3) that a bioaugmentation approach can substantially enhance in situ bioremediation if the requisite amendments can be adequately distributed throughout the fractured rock matrix.

Mild traumatic brain injury (TBI) persistent post-concussion syndrome (PPCS) and post-traumatic stress disorder (PTSD) are epidemic in United States Iraq and Afghanistan War veterans. Treatment of the combined diagnoses is limited. The aim of this study is to assess safety, feasibility, and effectiveness of hyperbaric oxygen treatments (HBOT) for mild TBI PPCS and PTSD. Thirty military subjects aged 18–65 with PPCS with or without PTSD and from one or more blast-induced mild-moderate traumatic brain injuries that were a minimum of 1 year old and occurred after 9/11/2001 were studied. The measures included symptom lists, physical exam, neuropsychological and psychological testing on 29 subjects (1 dropout) and SPECT brain imaging pre and post HBOT. Comparison was made using SPECT imaging on 29 matched Controls. Side effects (30 subjects) experienced due to the HBOT: reversible middle ear barotrauma (n = 6), transient deterioration in symptoms (n = 7), reversible bronchospasm (n = 1), and increased anxiety (n = 2; not related to confinement); unrelated to HBOT: ureterolithiasis (n = 1), chest pain (n = 2). Significant improvement (29 subjects) was seen in neurological exam, symptoms, intelligence quotient, memory, measures of attention, dominant hand motor speed and dexterity, quality of life, general anxiety, PTSD, depression (including reduction in suicidal ideation), and reduced psychoactive medication usage. At 6-month follow-up subjects reported further symptomatic improvement. Compared to Controls the subjects' SPECT was significantly abnormal, significantly improved after 1 and 40 treatments, and became statistically indistinguishable from Controls in 75% of abnormal areas. HBOT was found to be safe and significantly effective for veterans with mild to moderate TBI PPCS with PTSD in all four outcome domains: clinical medicine, neuropsychology, psychology, and SPECT imaging. Veterans also experienced a significant reduction in suicidal ideation and reduction in psychoactive medication use. PMID:29152209

The present study was designed to evaluate effectiveness of 1.2% atorvastatin (ATV) gel, as an adjunct to scaling and root planing (SRP) in the treatment of intrabony defects in chronic periodontitis (CP) in patients with type 2 diabetes mellitus (t2DM). Seventy-five patients were categorized into two treatment groups: 1) SRP plus 1.2% ATV and 2) SRP plus placebo. Clinical parameters including modified sulcus bleeding index, probing depth (PD), and relative attachment level (RAL) were recorded at baseline and 3, 6, and 9 months. Percentage radiographic defect depth reduction was evaluated using computer-aided software at baseline and 6 and 9 months. Mean PD reduction and mean RAL gain was greater in the ATV group than the placebo group at 3, 6, and 9 months. Furthermore, ATV group sites presented with a significantly greater percentage of radiographic defect depth reduction at 6 and 9 months. Locally delivered ATV was found to be effective in treatment of intrabony defects in CP in patients with t2DM.

Acute unilateral vestibulopathy (AUV) is characterized by acute vertigo, nausea, and imbalance without neurological deficits or auditory symptomatology. Here, we explore the effect of glucocorticoid treatment on the degree of canal paresis in patients with AUV, and critically, establish its relationship with dizziness symptom recovery. We recruited consecutive patients who were retrospectively assigned to one of the two groups according to whether they received glucocorticoid treatment (n = 32) or not (n = 44). All patients underwent pure-tone audiometry, bithermal caloric testing, MRI brain imaging, and were asked to complete a dizziness handicap inventory on admission to hospital and just prior to hospital discharge. In the treatment group, the canal paresis at discharge was significantly lower than in the control group (mean ± SD % 38.04 ± 21.57 versus 82.79 ± 21.51, p < 0.001). We also observed a significant reduction in the intensity of nystagmus in patients receiving glucocorticoid treatment compared to the non-treatment group (p = 0.03). DHI test score was significantly lower at discharge in the treatment group (mean ± SD % 23.15 ± 12.40 versus 64.07 ± 12.87, p < 0.001), as was the length of hospital stay (2.18 ± 1.5 days versus 3.6 ± 1.7 days, p = 0.002). Glucocorticoid treatment leads to acute symptomatic improvement, with a reduced hospital stay and reduction in the intensity of acute nystagmus. Our findings suggest that glucocorticoids may accelerate vestibular compensation via a restoration of peripheral vestibular function, and therefore has important clinical implications for the treatment of AUV.

Bactericidal activity of neutral electrolyzed water (NEW), quaternary ammonium (QUAT), and lactic acid-based solutions was investigated using a manual spraying technique against Salmonella Typhimurium, Escherichia coli O157:H7, Campylobacter jejuni, Listeria monocytogenes and Staphylococcus aureus that were inoculated onto the surface of scarred polypropylene and wooden food cutting boards. Antimicrobial activity was also examined when using cutting boards in preparation of raw chopped beef, chicken tenders or salmon fillets. Viable counts of survivors were determined as log10 CFU/100 cm(2) within 0 (untreated control), 1, 3, and 5 min of treatment at ambient temperature. Within the first minute of treatment, NEW and QUAT solutions caused more than 3 log10 bacterial reductions on polypropylene surfaces whereas less than 3 log10 reductions were achieved on wooden surfaces. After 5 min of treatment, more than 5 log10 reductions were achieved for all bacterial strains inoculated onto polypropylene surfaces. Using NEW and QUAT solutions within 5 min reduced Gram-negative bacteria by 4.58 to 4.85 log10 compared to more than 5 log10 reductions in Gram-positive bacteria inoculated onto wooden surfaces. Lactic acid treatment was significantly less effective (P < 0.05) compared to NEW and QUAT treatments. A decline in antimicrobial effectiveness was observed (0.5 to <2 log10 reductions were achieved within the first minute) when both cutting board types were used to prepare raw chopped beef, chicken tenders or salmon fillets. © 2016 Institute of Food Technologists®

Biofouling remains a key challenge for membrane-based water treatment systems. This study investigated the dispersal potential of the nitric oxide (NO) donor compound, PROLI NONOate, on single- and mixed-species biofilms formed by bacteria isolated from industrial membrane bioreactor and reverse osmosis (RO) membranes. The potential of PROLI NONOate to control RO membrane biofouling was also examined. Confocal microscopy revealed that PROLI NONOate exposure induced biofilm dispersal in all but two of the bacteria tested and successfully dispersed mixed-species biofilms. The addition of 40 μM PROLI NONOate at 24-h intervals to a laboratory-scale RO system led to a 92% reduction in the rate of biofouling (pressure rise over a given period) by a bacterial community cultured from an industrial RO membrane. Confocal microscopy and extracellular polymeric substances (EPS) extraction revealed that PROLI NONOate treatment led to a 48% reduction in polysaccharides, a 66% reduction in proteins, and a 29% reduction in microbial cells compared to the untreated control. A reduction in biofilm surface coverage (59% compared to 98%, treated compared to control) and average thickness (20 μm compared to 26 μm, treated compared to control) was also observed. The addition of PROLI NONOate led to a 22% increase in the time required for the RO module to reach its maximum transmembrane pressure (TMP), further indicating that NO treatment delayed fouling. Pyrosequencing analysis revealed that the NO treatment did not significantly alter the microbial community composition of the membrane biofilm. These results present strong evidence for the application of PROLI NONOate for prevention of RO biofouling. PMID:25636842

To study the curative effect and safety of rotatory manual reduction with forceps holder and retrograde percutaneous pinning transfixation in treating clavicular fracture. All 201 cases of clavicular fractures were randomly divided into treatment group (101 cases) and control group (100 cases). The treatment group was treated by rotatory manual reduction with forceps holder and retrograde percutaneous pinning transfixation. The control group was treated by open reduction and internal fixation with Kirschner pin. All cases were followed up for 4 to 21 months (mean 10.6 months). SPSS was used to analyze clinic healing time of fracture and shoulder-joint function in both two groups. After operation, 101 cases of treatment group achieved union of fracture and the clinical healing time was 28 to 49 days (mean 34.5+/-2.7 days). In control group,there were 4 cases with nonunion of fracture,the other 96 cases were union,the clinical healing time was 36 to 92 days (mean 55.3+/-4.8 days). The excellent and good rate of shoulder-joint function was 100% in treatment group and 83% in control group. By t-test and chi2-test, there was significant difference between the two groups in curative effect (P<0.05). Rotatory manual reduction with forceps holder and retrograde pinning transfixation can be used in various kinds of clavicular shaft fracture, with many virtues such as easy operation, reliable fixation, short union time of fracture, good functional recovery of shoulder-joint and no incision scar affecting appearance.

The long-chain n-3 fatty acids in fish have been demonstrated to have antiarrhythmic properties in experimental models and to prevent sudden cardiac death in a randomized trial of post-myocardial infarction patients. Therefore, we hypothesized that these n-3 fatty acids might prevent potentially fatal ventricular arrhythmias in high-risk patients. Four hundred two patients with implanted cardioverter/defibrillators (ICDs) were randomly assigned to double-blind treatment with either a fish oil or an olive oil daily supplement for 12 months. The primary end point, time to first ICD event for ventricular tachycardia or fibrillation (VT or VF) confirmed by stored electrograms or death from any cause, was analyzed by intention to treat. Secondary analyses were performed for "probable" ventricular arrhythmias, "on-treatment" analyses for all subjects who had taken any of their oil supplements, and "on-treatment" analyses only of those subjects who were on treatment for at least 11 months. Compliance with double-blind treatment was similar in the 2 groups; however, the noncompliance rate was high (35% of all enrollees). In the primary analysis, assignment to treatment with the fish oil supplement showed a trend toward a prolonged time to the first ICD event (VT or VF) or of death from any cause (risk reduction of 28%; P=0.057). When therapies for probable episodes of VT or VF were included, the risk reduction became significant at 31%; P=0.033. For those who stayed on protocol for at least 11 months, the antiarrhythmic benefit of fish oil was improved for those with confirmed events (risk reduction of 38%; P=0.034). Although significance was not achieved for the primary end point, this study provides evidence that for individuals at high risk of fatal ventricular arrhythmias, regular daily ingestion of fish oil fatty acids may significantly reduce potentially fatal ventricular arrhythmias.

To determine the relative influence of sleep continuity (sleep efficiency, sleep onset latency, total sleep time [TST], and wake after sleep onset) on clinical pain outcomes within a trial of cognitive behavioral therapy for insomnia (CBT-I) for patients with comorbid knee osteoarthritis and insomnia. Secondary analyses were performed on data from 74 patients with comorbid insomnia and knee osteoarthritis who completed a randomized clinical trial of 8-session multicomponent CBT-I versus an active behavioral desensitization control condition (BD), including a 6-month follow-up assessment. Data used herein include daily diaries of sleep parameters, actigraphy data, and self-report questionnaires administered at specific time points. Patients who reported at least 30% improvement in self-reported pain from baseline to 6-month follow-up were considered responders (N = 31). Pain responders and nonresponders did not differ significantly at baseline across any sleep continuity measures. At mid-treatment, only TST predicted pain response via t tests and logistic regression, whereas other measures of sleep continuity were nonsignificant. Recursive partitioning analyses identified a minimum cut-point of 382 min of TST achieved at mid-treatment in order to best predict pain improvements 6-month posttreatment. Actigraphy results followed the same pattern as daily diary-based results. Clinically significant pain reductions in response to both CBT-I and BD were optimally predicted by achieving approximately 6.5 hr sleep duration by mid-treatment. Thus, tailoring interventions to increase TST early in treatment may be an effective strategy to promote long-term pain reductions. More comprehensive research on components of behavioral sleep medicine treatments that contribute to pain response is warranted. © Sleep Research Society 2016.

Objective Treatment for alcohol use disorder (AUD) is far less effective for those with a co-occurring anxiety disorder. Surprisingly, adding an independent anxiety treatment to AUD treatment does not substantially improve the poor alcohol outcomes of these patients. This may reflect the lack of attention from independent treatments to the dynamic interaction of anxiety symptoms with alcohol use and drinking motivation. On the basis of this view, we assembled a cognitive behavioral therapy (CBT) program designed to both reduce anxiety symptoms and weaken the links between the experience of anxiety and the motivation to drink. Method 344 patients undergoing residential AUD treatment with current social phobia, generalized anxiety disorder, or panic disorder were randomly assigned to receive either the CBT or an active comparison treatment, Progressive Muscle Relaxation Training (PMRT). Assessments took place immediately following treatment and 4 months later (n = 247). Results As predicted, the CBT group demonstrated significantly better alcohol outcomes 4 months following treatment than did the PMRT group. Although both groups experienced a substantial degree of anxiety reduction following treatment, there were no significant group differences immediately after treatment and only a slight advantage for the CBT group 4 months after treatment. Conclusions These findings suggest that specific interventions aimed at weakening the association between the experience of anxiety and drinking motivation play an important role in improving the alcohol outcomes of these difficult-to-treat patients beyond that of anxiety reduction alone.

Six sewage treatment plants (STP) were investigated over a 12-month period in order to measure the microbiological load of untreated municipal wastewater and to evaluate the removal efficiencies of different treatment systems. The STP investigated can be classified into three categories: bigger plants with tertiary treatment, smaller plants with enhanced secondary treatment, and very small compact facilities. The plants studied had a considerable quantitative impact on the hydrology of the catchment area; consequently, it was anticipated that the microbiological load of the effluent would also be significant. Eighty samples were taken from the influent and effluent of the STP, regardless of weather conditions, and several bacterial and two parasitological parameters were analysed. The average microbiological reduction of each STP was dependent on its capacity and treatment procedures and varied between 1.9 and 3.5log10. Small compact facilities had a significantly lower removal efficiency (2.0+/-1log10) and discharged treated wastewater with a poorer microbiological quality compared to larger plants with tertiary treatment or with enhanced secondary treatment (2.8log10). Final sand filtration and extensive intermediate settling considerably improved the overall microbiological removal efficiency. During the study period, the microbiological water quality of the receiving water course was not significantly impaired by the discharge of any of the investigated plants; however, the compact facilities showed critical treatment deficiencies. In particular, the reduction of Giardia cysts was insufficient (<1.5log10) compared to that of the bigger plants (>3.0log10). In order to quantify the overall impact of microbiological loads on the receiving watercourse in this catchment area, it is also necessary to assess the pollution from combined sewer overflow basins and diffuse pollution. This will be considered in subsequent studies.

Experimental groups of 15 susceptible 3-week-old turkeys were inoculated oculonasally with avian metapneumovirus (APV) subtype A and susceptible Escherichia coli O2:K1 and Ornithobacterium rhinotracheale (ORT) bacteria, with a 3 days interval between viral and bacterial inoculation and approximately 8h between the two bacterial inoculations. The aims of the present study were to assess the efficacy of drinking-water administration of enrofloxacin for 3 and 5 days, amoxicillin for 5 days and florfenicol for 5 days for the treatment of the resulting respiratory disease, based on clinical and bacteriological examinations. Antimicrobial treatment started 1 day after dual bacterial inoculation. After infection, the birds were examined and scored for clinical signs daily, weighed at different times, and their tracheae swabbed daily. Five birds were euthanised and examined for macroscopic lesions at necropsy at 5 days post-bacterial inoculation (dpbi) and the remainder at 15dpbi. Samples of the turbinates, trachea, lungs, sinuses, air sacs, heart, pericardium and liver were collected for bacteriological examination. Recovery from respiratory disease caused by an APV/E. coli/ORT triple infection in 3-week-old turkey poults was overall most successful after enrofloxacin treatment, irrespective of treatment duration, followed by florfenicol treatment. Compared with the untreated group, clinical signs as well as ORT and E. coli multiplication in the respiratory tract were significantly reduced by both enrofloxacin treatments and the florfenicol treatment, with the enrofloxacin treatments showing significantly better reductions than the florfenicol treatment. Five-day treatment with amoxicillin, compared with the untreated group, did not cause a significant reduction in any of the aforementioned parameters.

Lumbar spondylosis is a degenerative disorder of the spine, whereby pain is a prominent feature that poses therapeutic challenges even after surgical intervention. There are no randomized, placebo-controlled studies utilizing repetitive spinal magnetic stimulation (SMS) in pain associated with lumbar spondylosis. In this study, we utilize SMS technique for patients with this condition in a pilot clinical trial. We randomized 20 patients into SMS treatment or placebo arms. All patients must have clinical and radiological evidence of lumbar spondylosis. Patients should present with pain in the lumbar region, localized or radiating down the lower limbs in a radicular distribution. SMS was delivered with a Medtronic R30 repetitive magnetic stimulator (Medtronic Corporation, Skovlunde, Denmark) connected to a C-B60 figure of eight coil capable of delivering a maximum output of 2 Tesla per pulse. The coil measured 90 mm in each wing and was centered over the surface landmark corresponding to the cauda equina region. The coil was placed flat over the back with the handle pointing cranially. Each patient on active treatment received 200 trains of five pulses delivered at 10 Hz, at an interval of 5 seconds between each train. "Sham" SMS was delivered with the coil angled vertically and one of the wing edges in contact with the stimulation point. All patients tolerated the procedure well and no side effects of SMS were reported. In the treatment arm, SMS had resulted in significant pain reduction immediately and at Day 4 after treatment (P < 0.05). In the placebo arm, however, no significant pain reduction was seen immediately and at Day 4 after SMS. SMS in the treatment arm had resulted in mean pain reduction of 62.3% postprocedure and 17.4% at Day 4. The placebo arm only achieved pain reduction of 6.1% postprocedure and 4.5% at Day 4. This is the first study to show that a single session of SMS resulted in significant improvement of pain associated with lumbar spondylosis in a randomized, double-blind, placebo-controlled setting. The novel findings support the potential of this technique for future studies pertaining to neuropathic pain. Wiley Periodicals, Inc.

Pirfenidone: a review of its use in idiopathic pulmonary fibrosis.

Kim, Esther S; Keating, Gillian M

2015-02-01

Pirfenidone (Esbriet®) is an orally administered, synthetic, pyridone compound that is approved for the treatment of adults with mild to moderate idiopathic pulmonary fibrosis (IPF) in the EU, and for the treatment of IPF in the USA. This article summarizes pharmacological, efficacy and tolerability data relevant to the use of pirfenidone in these indications. In the randomized, double-blind, placebo-controlled, multinational CAPACITY trials in patients with mild to moderate IPF, a significant reduction in the rate of decline in forced vital capacity (FVC) was seen with pirfenidone versus placebo in study 004 but not in study 006. Pirfenidone also reduced the rate of decline in FVC to a significantly greater extent than placebo in the randomized, double-blind, multinational ASCEND trial in this patient population. In addition, pirfenidone showed a significant treatment effect on the 6-min walking test distance and progression-free survival in the ASCEND trial and in a pooled analysis of the CAPACITY trials. Pirfenidone had a manageable tolerability profile in all three studies. Gastrointestinal and skin-related events (e.g. nausea, rash, photosensitivity reaction), which were the most commonly occurring treatment-emergent adverse events, were generally mild to moderate in severity. In addition, a prespecified mortality analysis across all three studies demonstrated a significant reduction in IPF-related and all-cause mortality with pirfenidone. In conclusion, oral pirfenidone is a valuable agent for use in patients with IPF.

The purpose of our study was to see the efficacy of 3 different modes of treatment for overactive bladder (OAB) in symptoms reduction and quality of life improvement. We conducted a 12-week single-blinded randomized controlled trial of women aged 22-65 years with clinical diagnosis of OAB. Arm A (n = 47) received bladder training, arm B (n = 50) received pelvic floor muscle training (PFMT), and arm C (n = 50) received PFMT with biofeedback. Bladder diary was used to assess the difference in urinary frequency, urgency, and leak accidents before and after treatment. Initial and final assessment was made using -validated urogenital distress inventory short form 6 (UDI-SF6) and incontinence impact questionnaire short form 7 (IIQ-SF7). UDI-SF6 scores showed significant improvement in all arms. There was a reduction in UDI-6 scores from 8.38 ± 4.3 to 4.77 ± 5.5 with a mean difference of 3.61 ± 7.4 in patients in arm A (p = 0.002), arm B (p = 0.01), and arm C (p = 0.016). All patients in arms A, B, and C reported significant improvement in quality of life as assessed by IIQ-SF7 scores with significant p values of 0.009, 0.051, and 0.001, respectively. Bladder diary results using paired t test showed the significant difference in day time urinary frequency in arm A after treatment, as well as the reduction in both leak accidents and urgency score in all 3 arms. All 3 arms of study showed significant results and can be used as the first line of management. © 2018 S. Karger AG, Basel.

Autonomic nervous system dysfunction in psychiatric disorders and the impact of psychotropic medications: a systematic review and meta-analysis

2016-01-01

Background Autonomic nervous system (ANS) dysfunction is a putative underlying mechanism for increased cardiovascular disease risk in individuals with psychiatric disorders. Previous studies suggest that this risk may be related to psychotropic medication use. In the present study we systematically reviewed and analyzed published studies of heart rate variability (HRV), measuring ANS output, to determine the effect of psychiatric illness and medication use. Methods We searched for studies comparing HRV in physically healthy adults with a diagnosed psychiatric disorder to controls and comparing HRV pre- and post-treatment with a psychotropic medication. Results In total, 140 case–control (mood, anxiety, psychosis, dependent disorders, k = 151) and 30 treatment (antidepressants, antipsychotics; k = 43) studies were included. We found that HRV was reduced in all patient groups compared to controls (Hedges g = −0.583) with a large effect for psychotic disorders (Hedges g = −0.948). Effect sizes remained highly significant for medication-free patients compared to controls across all disorders. Smaller and significant reductions in HRV were observed for specific antidepressants and antipsychotics. Limitations Study quality significantly moderated effect sizes in case–control analyses, underscoring the importance of assessing methodological quality when interpreting HRV findings. Conclusion Combined findings confirm substantial reductions in HRV across psychiatric disorders, and these effects remained significant even in medication-free individuals. Reductions in HRV may therefore represent a significant mechanism contributing to elevated cardiovascular risk in individuals with psychiatric disorders. The negative impact of specific medications on HRV suggest increased risk for cardiovascular disease in these groups, highlighting a need for treatment providers to consider modifiable cardiovascular risk factors to attenuate this risk.

2006-01-01

The medical records of 2239 patients (mean age=73 years) with established peripheral neuropathy (PN) were examined to determine whether treatment with MIRE was, in fact, associated with increased foot sensitivity to the Semmes Weinstein monofilament (SWM) 5.07 and a reduction in neuropathic pain. The PN in 1395 of these patients (62%) was due to diabetes. Prior to treatment with MIRE, of the 10 tested sites (5 on each foot), 7.1+/-2.9 were insensitive to the SWM 5.07, and 2078 patients (93%) exhibited loss of protective sensation defined by Medicare as a loss of sensation at two or more sites on either foot. After treatment, the number of insensate sites on both feet decreased to 2.4+/-2.6, an improvement of 66%. Of the 2078 (93%) patients initially presenting with loss of protective sensation, 1106 (53%) no longer had loss of protective sensation after treatment (P<.0001); 1563 patients (70%) also exhibited neuropathic pain in addition to sensory impairment. Prior to treatment with MIRE, pain measured on the 11-point visual analogue scale (VAS) was 7.2+/-2.2 points, despite the use of a variety of pain-relieving therapeutic agents. After treatment with MIRE, pain was reduced by 4.8+/-2.4 points, a 67% reduction. Therefore, MIRE appears to be associated with significant clinical improvement in foot sensation and, simultaneously, a reduction in neuropathic pain in a large cohort of primarily Medicare aged, community-dwelling patients, initially diagnosed with PN. The quality of life associated with these two outcomes cannot be underappreciated.

In order to provide a scientific basis for rational use of antibiotics, we studied and compared the therapeutic effects of step-down and step-up antibiotic treatment schemes in children with lobar pneumonia. Eighty cases of children with lobar pneumonia were enrolled in this study and were randomly divided into two groups: The observation group and the control group, with 40 cases in each group. In the observation group, there were 23 cases with mild and 17 cases with severe lobar pneumonia, and in the control group, 25 were mild and 15 were severe cases. Patients in the control group were treated with antibiotics using step-up therapy method, while patients in the observation group were treated using step-down antibiotic therapy. Our results showed no significant differences in white blood cell (WBC) reduction rate, the course of antibiotic treatment, disappearance time of pulmonary rales and total efficiency in children with mild lobar pneumonia in the observation group after 72 h of treatment. The level of high-sensitivity C-reactive protein (hs-CRP) and procalcitonin (PCT) in the observation group were significantly lower. After 72 h of treatment of children with severe lobar pneumonia in the observation group, the rate of WBC reduction accelerated significantly. Compared to the patients in the control group, the course of antibiotic treatment and disappearance time of pulmonary rales were shortened significantly, while the total efficiency of treatment was improved considerably in the observation group. Also in the observation group, hs-CRP and PCT levels were significantly lower than that in the control group. In severe cases, step-down therapy showed a better result in relieving the inflammatory reactions. The disappearance time of pulmonary rales and the effective rate of treatment was significantly higher than those of step-up therapy. It was obvious that for children with severe lobar pneumonia, step-down therapy produced better results in relieving the inflammatory reaction.

Addition of fumaric acid and sodium benzoate as an alternative method to achieve a 5-log reduction of Escherichia coli O157:H7 populations in apple cider.

A study was conducted to develop a preservative treatment capable of the Food and Drug Administration-mandated 5-log reduction of Escherichia coli O157:H7 populations in apple cider. Unpreserved apple cider was treated with generally recognized as safe acidulants and preservatives before inoculation with E. coli O157:H7 in test tubes and subjected to mild heat treatments (25, 35, and 45 degrees C) followed by refrigerated storage (4 degrees C). Fumaric acid had significant (P < 0.05) bactericidal effect when added to cider at 0.10% (wt/vol) and adjusted to pH 3.3, but citric and malic acid had no effect. Strong linear correlation (R2 = 0.96) between increasing undissociated fumaric acid concentrations and increasing log reductions of E. coli O157:H7 in apple cider indicated the undissociated acid to be the bactericidal form. The treatment that achieved the 5-log reduction in three commercial ciders was the addition of fumaric acid (0.15%, wt/vol) and sodium benzoate (0.05%, wt/vol) followed by holding at 25 degrees C for 6 h before 24 h of refrigeration at 4 degrees C. Subsequent experiments revealed that the same preservatives added to cider in flasks resulted in a more than 5-log reduction in less than 5 and 2 h when held at 25 and 35 degrees C, respectively. The treatment also significantly (P < 0.05) reduced total aerobic counts in commercial ciders to populations less than those of pasteurized and raw ciders from the same source (after 5 and 21 days of refrigerated storage at 4 degrees C, respectively). Sensory evaluation of the same ciders revealed that consumers found the preservative-treated cider to be acceptable.

The Neurobiological Mechanism of Chemical Aversion (Emetic) Therapy for Alcohol Use Disorder: An fMRI Study

2017-01-01

A recent NIH epidemiology study found the lifetime prevalence of alcohol use disorder in the United States to be 29%. Alcohol drinking behavior is strongly “learned” via pleasure center activation/reinforcement. Alcohol craving is a powerful desire to drink alcoholic beverages. Craving was added as one of the defining criteria for alcohol use disorder in DSM5, and craving reduction is becoming an increasingly important treatment goal. In the current study, patients with alcohol use disorder received 10 days of inpatient multi-modal treatments at Schick Shadel Hospital (SSH) of Seattle. The treatments included five chemical aversion conditioning sessions that associated alcohol cues (and alcohol) with nausea and emesis. All patients met DSM4 criteria for alcohol use disorder, were heavy drinkers, and reported craving alcohol pre-treatment. Craving reduction was one of the primary treatment goals. This is the first fMRI study to measure the effects of chemical aversion therapy on alcohol craving-related brain activity. Patients were recruited as subjects for the University of Washington (UW) brain scan study following SSH admission but before treatment onset. Prior to treatment, patients reported craving/desire for alcohol. After treatment (after four SSH chemical aversion treatments, again after five SSH chemical treatments, 30 and 90-days post-discharge), these same patients reported avoidance/aversion to alcohol. Most of the participants (69%) reported being still sober 12 months post-treatment. Consistent with a craving reduction mechanism of how chemical aversion therapy facilitates sobriety, results of the UW fMRI brain scans showed significant pre- to post-treatment reductions in craving-related brain activity in the occipital cortex. Additional fMRI brain scan studies are needed to further explore the neurobiological mechanism of chemical aversion therapy treatment for alcohol use disorder, and other substance use disorders for which chemical aversion therapy is used (e.g., opioid dependence and cocaine dependence). Substance use disorders are estimated to affect well over one billion people worldwide. PMID:29033802

It is unclear how changes in body composition induced by sodium-glucose cotransporter 2 (SGLT2) inhibitor treatment correlate with metabolic profile changes. We aimed to clarify how metabolic profile changes correlate with body component changes, and if SGLT2 inhibitor treatment causes sarcopenia and bone mineral content (BMC) loss. Moderately obese Japanese type 2 diabetes (T2D) patients, treated with luseogliflozin for a year, were observed prospectively and evaluated for body composition changes. We analyzed the changes in the individual body components during treatment, and their correlation with other clinical variables. The efficacy analysis set comprised 37 of 43 enrolled patients. The total fat mass significantly decreased early in the treatment at and after Week 4, with a mean decrease of -1.97 kg [95% CI: -2.66 to -1.28] at Week 24. The visceral fat area at Week 24 showed an average downward trend, although this was not significant. The changes in visceral fat area in individual patients demonstrated a significant negative correlation with the extent of the baseline visceral fat area (r=-0.399, p=0.023). The skeletal muscle mass index exhibited a significant but small change at and after Week 36. The BMC profile showed a transient significant decrease only at Week 12. No significant change in BMC was noted at other time points. Luseogliflozin treatment brought about favorable changes in body composition and metabolism of moderately obese Japanese T2D patients, accompanied by body fat reduction and minimal muscle and BMC reduction.

With the popularization of municipal sewage treatment facilities, the improvement of sewage treatment efficiency and the deepening degree of sewage treatment, the sludge production of sewage plant has been sharply increased. Carbon emission during the process of municipal sewage treatment and disposal has become one of the important sources of greenhouse gases that cause greenhouse effect. How to reduce carbon dioxide emissions during sewage treatment and disposal process is of great significance for reducing air pollution. Kitchen waste and excess sludge, as two important organic wastes, once uses anaerobic synergetic digestion technology in the treatment process can on the one hand, avoid instability of sludge individual anaerobic digestion, improve sludge degradation rate and marsh gas production rate, and on the other hand, help increase the reduction of carbon dioxide emissions to a great extent. The paper uses material balance method, analyzes and calculates the carbon dioxide emissions from kitchen waste and sludge disposed by the anaerobic synergetic digestion technology, compares the anaerobic synergetic digestion technology with traditional sludge sanitary landfill technology and works out the carbon dioxide emission reductions after synergetic digestion. It takes the kitchen waste and sludge synergetic digestion engineering project of Zhenjiang city in Jiangsu province as an example, makes material balance analysis using concrete data and works out the carbon dioxide daily emission reductions. The paper analyzes the actual situation of emission reduction by comparing the data, and found that the synergetic digestion of kitchen waste and sludge can effectively reduce the carbon dioxide emission, and the reduction is obvious especially compared with that of sludge sanitary landfill, which has a certain effect on whether to promote the use of the technology.

Alcohol septal ablation and surgical myectomy represent accepted therapeutic options for treatment of symptomatic patients with hypertrophic obstructive cardiomyopathy. Long-term experience with radiofrequency ablation of arrhythmogenic substrates raised a question if this technique might be effective for left ventricular outflow tract (LVOT) gradient reduction. We report on a 63-year-old patient with recurrence of symptoms 1 year after alcohol septal ablation (ASA) leading originally to a significant reduction of both symptoms and gradient. Due to a new increase of gradient in the LVOT up to 200 mm Hg with corresponding worsening of symptoms and due to refusal of surgical myectomy by the patient, endocardial radiofrequency ablation of the septal hypertrophy (ERASH) was indicated. Radiofrequency ablation was performed in the LVOT using irrigated-tip ablation catheter; the target site was identified using intracardiac echocardiography and electroanatomical CARTO mapping. ERASH caused an immediate gradient reduction due to hypokinesis of the ablated septum. At 2-month follow-up exam, significant clinical improvement was observed, together with persistent gradient reduction assessed with Doppler echocardiography. Echocardiography and magnetic resonance revealed persistent septal hypokinesis and slight thinning of the ablated region. Septal ablation using radiofrequency energy may be a promising alternative or adjunct to the treatment of hypertrophic obstructive cardiomyopathy. Intracardiac echocardiography and electroanatomical CARTO mapping enable exact lesion placement and preservation of atrioventricular conduction.

Simultaneous minimization of leaf travel distance and tongue-and-groove effect for segmental intensity-modulated radiation therapy.

PubMed

Dai, Jianrong; Que, William

2004-12-07

This paper introduces a method to simultaneously minimize the leaf travel distance and the tongue-and-groove effect for IMRT leaf sequences to be delivered in segmental mode. The basic idea is to add a large enough number of openings through cutting or splitting existing openings for those leaf pairs with openings fewer than the number of segments so that all leaf pairs have the same number of openings. The cutting positions are optimally determined with a simulated annealing technique called adaptive simulated annealing. The optimization goal is set to minimize the weighted summation of the leaf travel distance and tongue-and-groove effect. Its performance was evaluated with 19 beams from three clinical cases; one brain, one head-and-neck and one prostate case. The results show that it can reduce the leaf travel distance and (or) tongue-and-groove effect; the reduction of the leaf travel distance reaches its maximum of about 50% when minimized alone; the reduction of the tongue-and-groove reaches its maximum of about 70% when minimized alone. The maximum reduction in the leaf travel distance translates to a 1 to 2 min reduction in treatment delivery time per fraction, depending on leaf speed. If the method is implemented clinically, it could result in significant savings in treatment delivery time, and also result in significant reduction in the wear-and-tear of MLC mechanics.

The reduction of sodium in processed meat products is synonymous with the use of salt replacers. Rarely has there been an assessment of the use of intermediate salt levels as a sodium reduction strategy in itself. In this study, 1 and 1.5% salt levels were compared with 0 and 2% controls in fresh pork sausages for effects on chemical, microbial, sensory and technological stability. Although significant (P < 0.001 to P < 0.01) differences were found between the 0 and 2% controls, no significant differences could be detected between the 2, 1.5 and 1% added NaCl treatments for the following: total bacteria counts on days 3, 6 and 9; TBARS of pork sausages stored at 4 °C on days 6 and 9 and stored at -18 °C on days 90 and 180; taste, texture and overall liking during sensory evaluation; and % cooking loss, % total loss and % refrigeration loss. Consumers were able to differentiate between the 2 and 1% added NaCl treatments in terms of saltiness. This study indicated that salt reduction to intermediate levels can be considered a sodium reduction strategy in itself but that further research with regards to product safety is needed. © 2015 Society of Chemical Industry. © 2015 Society of Chemical Industry.

Despite some preliminary evidence, it is still largely unknown whether osteopathic manipulative treatment improves preterm clinical outcomes. The present multi-center randomized single blind parallel group clinical trial enrolled newborns who met the criteria for gestational age between 29 and 37 weeks, without any congenital complication from 3 different public neonatal intensive care units. Preterm infants were randomly assigned to usual prenatal care (control group) or osteopathic manipulative treatment (study group). The primary outcome was the mean difference in length of hospital stay between groups. A total of 695 newborns were randomly assigned to either the study group (n= 352) or the control group (n=343). A statistical significant difference was observed between the two groups for the primary outcome (13.8 and 17.5 days for the study and control group respectively, p<0.001, effect size: 0.31). Multivariate analysis showed a reduction of the length of stay of 3.9 days (95% CI -5.5 to -2.3, p<0.001). Furthermore, there were significant reductions with treatment as compared to usual care in cost (difference between study and control group: 1,586.01€; 95% CI 1,087.18 to 6,277.28; p<0.001) but not in daily weight gain. There were no complications associated to the intervention. Osteopathic treatment reduced significantly the number of days of hospitalization and is cost-effective on a large cohort of preterm infants.

Indocyanine green (ICG) is a photosensitizer recently introduced for the treatment of acne. To evaluate the efficacy and safety of photodynamic therapy (PDT) using ICG in subjects with acne vulgaris and to evaluate whether there was a difference in the efficacy of ICG-PDT between different numbers of treatment. Subjects with acne on the face were included. ICG lotion (0.1%) was applied for 30 minutes, and a long pulse diode laser was used. Three or five treatments per subject were performed over 2 weeks. Acne lesion counts and Leeds revised acne grades were evaluated at baseline and 2 weeks after the last treatment. In total, 47 subjects completed the study. After both three and five ICG-PDT sessions, a significant reduction in acne lesions and significant improvement in Leeds revised acne grades were found in all treated subjects compared to baseline. In the subjects receiving five ICG-PDT sessions, the reduction of papules/pustules was greater than in the subjects receiving three ICG-PDT sessions (P < 0.01, respectively). However, there was no significant change in the count of nodules/cysts, although it is a negative trend (P = 0.066). Adverse effects were minimal. ICG-PDT using long-pulsed diode laser can be a safe and effective tool for acne vulgaris. Moreover, repetitive treatments of five can cause further improvement of inflammatory acne lesions. © 2016 The International Society of Dermatology.

Two antimicrobial shampoos for treatment of canine Malassezia dermatitis (CMD) were compared in a prospective, randomised, single-blinded, field clinical trial. Sixty-seven dogs with pedal or generalised dermatitis associated with Malassezia overgrowth (MO) were treated with 3% chlorhexidine shampoo (3%CHX) or 2% miconazole-2% chlorhexidine shampoo (2%MIC/CHX) and evaluated for up to 6 weeks until cytological recovery. Pruritus, erythema, papules, greasy seborrhoea, scaling, malodour, excoriations, secondary hairloss, lichenification, hyperpigmentation and lesion extent were each scored on a 0-3 severity scale and combined making an aggregate score. Among 54 dogs with good treatment compliance, reduction of yeast counts by at least 88% was recorded in 21 of 22 dogs with 3%CHX and 30 of 32 dogs with 2%MIC/CHX. No significant difference was detected between products for yeast count reduction (P=0·592). Time to cytological recovery was not significantly different between groups (P=0·960). Lesion score was significantly reduced in both groups after treatment (72·5 ±25·7% with 3%CHX versus 78·7 ±22·3% with 2%MIC/CHX, P=0·309). Four dogs treated with chlorhexidine shampoo showed minor adverse effects. In this study, 3%CHX was clinically as effective as 2%MIC/CHX for treatment of CMD. © 2011 British Small Animal Veterinary Association.

Many studies described the safety and effectiveness of laparoscopy in the treatment of inguinal hernia in children. Needlescopic techniques have been recently used in repairing inguinal hernias, which made this type of surgery more cosmetic and less invasive. However, few reports have described its role in the treatment of incarcerated inguinal hernia. The aim of this study was to assess the feasibility and outcome of needlescopy in the treatment of incarcerated inguinal hernia in children. A total of 250 children, comprising 190 boys and 60 girls, who presented with incarcerated inguinal hernia were analyzed. Their ages ranged from 6 months to 6 years (mean age, 2 years). In 170 (68%) cases, manual reduction was successful. One hundred of these patients were subjected to definitive surgery in the same day, whereas the remaining 70 patients were subjected to needlescopy 1 to 3 days later. In 80 (32%) cases, external manual reduction was unsuccessful. These children were subjected to urgent needlescopic reduction and herniorrhaphy. The incarcerated herniae were easily reduced and the contents thoroughly inspected under direct vision. Then the hernia was repaired in the same setting. In all patients, there was no need to convert the procedure to an open approach. Immediate needlescopic herniorrhaphy in the same session was added without significant increase in operative time. The mean operative time is 10 minutes. There were no intraoperative complications. The study showed that needlescopic approach to incarcerated inguinal hernia in children is feasible, safe, easy, and preferable to the open surgery. In addition to reduction of incarcerated hernial contents under direct vision, it allows definitive treatment of hernial defect at the same time without significant increase in operative time and hospital stay.

Aripiprazole in pediatric psychosis and bipolar disorder: a clinical review.

PubMed

Doey, Tamison

2012-01-01

Aripiprazole is an atypical antipsychotic with unique pharmacological properties, used for a variety of indications, including psychotic and mood disorders in youth. Existing literature was reviewed to summarize experience with this agent in that population. A review of relevant literature using the key words aripiprazole, children, pediatric, all child, schizophrenia, bipolar disorder, and atypical antipsychotics was conducted. A total of 140 articles and book chapters were identified, of which 7 reported double-blind controlled trials with aripiprazole, 5 were meta-analyses of pooled data, 11 were open label trials, 10 were chart reviews, and 17 were case reports or case series. Although every effort was made to locate all available data, some information from posters or researchers was not available. Publication bias tends to report positive outcomes with a treatment, while negative studies are less likely to be reported. Most trials are of short duration. Treatment with aripiprazole is associated with significant reduction of the Positive and Negative Symptom Scale (PANSS) scores in youth with schizophrenia, and reductions in items in the negative symptom scores at higher doses (30 mg/day). Significant reductions in the Young Mania Rating Scale (YMRS) have been demonstrated in youth with bipolar disorder. In mixed populations, reductions in the Clinical Global Impressions Scale (CGI-S) have also been demonstrated when compared with treatment with placebo. Head-to-head comparisons are fewer in number, and overall aripiprazole compares favorably with other atypical antipsychotics (ATAs) in the populations studied. Treatment with aripiprazole is reported to have a lower incidence of weight gain, and less elevation of prolactin. At higher doses, it appears more likely to result in extrapyramidal symptoms (EPS) and tremor. Copyright © 2012. Published by Elsevier B.V.

The aim of this study was to assess the clinical efficacy and safety of oral ginger for symptomatic treatment of osteoarthritis (OA) by carrying out a systematic literature search followed by meta-analyses on selected studies. Inclusion criteria were randomized controlled trials (RCTs) comparing oral ginger treatment with placebo in OA patients aged >18 years. Outcomes were reduction in pain and reduction in disability. Harm was assessed as withdrawals due to adverse events. The efficacy effect size was estimated using Hedges' standardized mean difference (SMD), and safety by risk ratio (RR). Standard random-effects meta-analysis was used, and inconsistency was evaluated by the I-squared index (I(2)). Out of 122 retrieved references, 117 were discarded, leaving five trials (593 patients) for meta-analyses. The majority reported relevant randomization procedures and blinding, but an inadequate intention-to-treat (ITT) analysis. Following ginger intake, a statistically significant pain reduction SMD = -0.30 ([95% CI: [(-0.50, -0.09)], P = 0.005]) with a low degree of inconsistency among trials (I(2) = 27%), and a statistically significant reduction in disability SMD = -0.22 ([95% CI: ([-0.39, -0.04)]; P = 0.01; I(2) = 0%]) were seen, both in favor of ginger. Patients given ginger were more than twice as likely to discontinue treatment compared to placebo ([RR = 2.33; 95% CI: (1.04, 5.22)]; P = 0.04; I(2) = 0%]). Ginger was modestly efficacious and reasonably safe for treatment of OA. We judged the evidence to be of moderate quality, based on the small number of participants and inadequate ITT populations.

Data of randomly controlled trials comparing the hydrostatic and pneumatic reduction for intussusception in pediatric patients as initial therapy are lacking. The aim of this study was to conduct a randomly controlled trial to compare the effectiveness and safety of the hydrostatic and pneumatic reduction techniques. All intussusception patients who visited West China Hospital of Sichuan University from January 2014 to December 2015 were enrolled in this study in which they underwent pneumatic reduction or hydrostatic reduction. Patients were randomized into ultrasound-guided hydrostatic or X-ray-guided pneumatic reduction group. The data collected includes demographic data, symptoms, signs, and investigations. The primary outcome of the study was the success rate of reduction. And the secondary outcomes of the study were the rates of intestinal perforations and recurrence. A total of 124 children with intussusception who had met the inclusion criteria were enrolled. The overall success rate of this study was 90.32%. Univariable analysis showed that the success rate of hydrostatic reduction with normal saline (96.77%) was significantly higher than that of pneumatic reduction with air (83.87%) (p=0.015). Perforation after reduction was found in only one of the pneumatic reduction group. The recurrence rate of intussusception in the hydrostatic reduction group was 4.84% compared with 3.23% of pneumatic reduction group. Our study found that ultrasound-guided hydrostatic reduction is a simple, safe and effective nonoperative treatment for pediatric patients suffering from intussusceptions, and should be firstly adopted in the treatment of qualified patients.

The objective of this study was to evaluate how treatment temperature influences the solubility of ClO 2 gas and the antimicrobial effect of ClO 2 gas against Escherichia coli O157:H7, Salmonella Typhimurium, and Listeria monocytogenes on produce and food contact surfaces. Produce and food contact surfaces inoculated with a combined culture cocktail of three strains each of the three foodborne pathogens were processed in a treatment chamber with 20 ppmv ClO 2 gas at 15 or 25 °C under the same conditions of absolute humidity (11.2-12.3 g/m 3 ) for up to 30 min. As treatment time increased, ClO 2 gas treatment at 15 °C caused significantly more (p < 0.05) inactivation of the three pathogens than treatment at 25 °C. ClO 2 gas treatment at 25 °C for 30 min resulted in 1.15 to 1.54, 1.53 to 1.88, and 1.00 to 1.78 log reductions of the three pathogens on spinach leaves, tomatoes, and stainless steel No.4, respectively. ClO 2 gas treatment at 15 °C for 30 min caused 2.53 to 2.88, 2.82 to 3.23, and 2.37 to 3.03 log reductions of the three pathogens on spinach leaves, tomatoes, and stainless steel No.4, respectively. Treatment with ClO 2 gas at 25 °C for 20 min resulted in 1.88 to 2.31 log reductions of the three pathogens on glass while >5.91 to 6.82 log reductions of these pathogens occurred after 20 min when treated at 15 °C. Residual ClO 2 levels after gas treatment at 15 °C were significantly (p < 0.05) higher than those at 25 °C. The results of this study can help the food processing industry establish optimum ClO 2 gas treatment conditions for maximizing the antimicrobial efficacy of ClO 2 gas. Published by Elsevier B.V.

To evaluate health-related quality of life (HRQOL) after salvage high-intensity focused ultrasound (HIFU) for locally radiorecurrent prostate cancer (PCa). Since June 2006 we have treated 61 patients consecutively by salvage HIFU. All patients were offered the University of California, Los Angeles Prostate Cancer Index (UCLA-PCI) questionnaire at baseline and at follow-up. Scores ranged from 0 (worst) to 100 (best). Clinically significant changes were defined as a minimum difference of 10 points between the baseline score and the score at follow-up.   Fifty-seven patients (93%) had evaluable data at baseline, compared with 46 (75%) after treatment. The mean time lapse between HIFU treatment and questionnaire response was 17.5 months (range 6-29 months). The mean score for urinary function decreased from 79.7 ± 12.1 prior to HIFU to 67.4 ± 17.8 after HIFU (P < 0.001). The mean score for sexual function decreased from 32.1 ± 24.1 prior to HIFU to 17.2 ± 17.0 after HIFU (P < 0.001). There were no significant effects on bowel function. There was a significant reduction in the mean score for Physical HRQOL, but the mean score for Mental HRQOL was did not change significantly. Treatment of localized radiorecurrent PCa by salvage HIFU is associated with clinically significant reductions in urinary and sexual function domains after a mean follow-up of 17.5 months. © 2011 The Japanese Urological Association.

Background Influenza is an important cause of morbidity and mortality for frail older people. Whilst the antiviral drug oseltamivir (a neuraminidase inhibitor) is approved for treatment and prophylaxis of influenza during outbreaks, there have been no trials comparing treatment only (T) versus treatment and prophylaxis (T&P) in Aged Care Facilities (ACFs). Our objective was to compare a policy of T versus T&P for influenza outbreaks in ACFs. Methods and Findings We performed a cluster randomised controlled trial in 16 ACFs, that followed a policy of either “T”—oseltamivir treatment (75 mg twice a day for 5 days)—or “T&P”—treatment and prophylaxis (75 mg once a day for 10 days) for influenza outbreaks over three years, in addition to enhanced surveillance. The primary outcome measure was the attack rate of influenza. Secondary outcomes measures were deaths, hospitalisation, pneumonia and adverse events. Laboratory testing was performed to identify the viral cause of influenza-like illness (ILI) outbreaks. The study period 30 June 2006 to 23 December 2008 included three southern hemisphere winters. During that time, influenza was confirmed as the cause of nine of the 23 ILI outbreaks that occurred amongst the 16 ACFs. The policy of T&P resulted in a significant reduction in the influenza attack rate amongst residents: 93/255 (36%) in residents in T facilities versus 91/397 (23%) in T&P facilities (p = 0.002). We observed a non-significant reduction in staff: 46/216 (21%) in T facilities versus 47/350 (13%) in T&P facilities (p = 0.5). There was a significant reduction in mean duration of outbreaks (T = 24 days, T&P = 11 days, p = 0.04). Deaths, hospitalisations and pneumonia were non-significantly reduced in the T&P allocated facilities. Drug adverse events were common but tolerated. Conclusion Our trial lacked power but these results provide some support for a policy of “treatment and prophylaxis” with oseltamivir in controlling influenza outbreaks in ACFs.

Except for the Providence River and side embayments like Greenwich Bay, Narragansett Bay can no longer be considered eutrophic. In summer 2012 managed nitrogen treatment in Narragansett Bay achieved a goal of reducing effluent dissolved inorganic nitrogen inputs by over 50%. Narragansett Bay represents a small northeast US estuary that had been heavily loaded with sewage effluent nutrients since the late 1800s. The input reduction was reflected in standing stock nutrients resulting in a statistically significant 60% reduction in concentration. In the Providence River estuary, total nitrogen decreased from 100 μm to about 40 μm, for example. We tested four environmental changes that might be associated with the nitrogen reduction. System apparent production was significantly decreased by 31% and 45% in the upper and mid Bay. Nutrient reductions resulted in statistically improved water clarity in the mid and upper Bay and in a 34% reduction in summer hypoxia. Nitrogen reduction also reduced the winter spring diatom bloom; winter chlorophyll levels after nutrient reduction have been significantly lower than before the reduction. The impact on the Bay will continue to evolve over the next few years and be a natural experiment for other temperate estuaries that will be experiencing nitrogen reduction. To provide perspective we review factors effecting hypoxia in other estuaries with managed nutrient reduction and conclude that, as in Narragansett Bay, physical factors can be as important as nutrients. On a positive note managed nutrient reduction has mitigated further deterioration in most estuaries.

Plasma C-reactive protein (CRP) is an inflammatory biomarker that predicts cardiovascular disease. We investigated whether vitamins C or E could reduce CRP. Healthy nonsmokers (n=396) were randomized to three groups:1000 mg/day vitamin C, 800 IU/day vitamin E, or placebo, for two months. Median baseline CRP was low, 0.85 mg/L. No treatment effect was seen when all participants are included. However, significant interaction was found, indicating that treatment effect depends on baseline CRP concentration. Among participants with CRP indicative of elevated cardiovascular risk (≥1.0 mg/L), vitamin C reduced median CRP by 25.3% vs. Placebo (p=0.02), (median reduction in the vitamin C group, 0.25 mg/L, 16.7%). These effects are similar to those of statins. The vitamin E effect was not significant. In summary, treatment with vitamin C but not E significantly reduced CRP among individuals with CRP ≥ 1.0 mg/L. Among the obese, 75% had CRP ≥ 1.0 mg/L. These data extend previous results in smokers, and identify CRP levels susceptible to reductions. Research is needed to determine whether reducing this inflammatory biomarker with vitamin C could reduce diseases associated with obesity. But research on clinical benefits of antioxidants should limit participants to persons with elevations in the target biomarkers. PMID:18952164

Antimicrobial photodynamic therapy (aPDT) is a novel technique for reduction of pathogenic microorganisms in dentistry. The aim of this study was to evaluate the effects of aPDT on Streptococcus mutans reduction in children with severe early childhood caries. Twenty-two children with severe early childhood caries aged 3-6 years were treated with toluoidine blue O (TBO) for 1min and irradiated by a Light Emitting Diode (LED; FotoSan, CMS Dental, Denmark) with the exposure time of 150s. Saliva samples were collected at baseline, 1h and 7 days after treatment. S. mutans counts were determined using the Dentocult SM Strip mutans. The counts of S. mutans in saliva decreased significantly after 1h (P<0.001). However, the difference in reduction of S. mutans counts in saliva was not significant between the baseline and 7 days after treatment (P>0.05). aPDT seems to be efficient to reduce salivary S. mutans immediately after treatment in children with severe early childhood caries. However, further research is needed to evaluate different doses and frequency of irradiation in combination with restoring carious teeth to find more durable results. Copyright © 2017 Elsevier B.V.

Metformin (MF), used for the treatment of type 2 diabetes mellitus, has shown to possess properties favoring osteoblastic proliferation. The present study was designed to investigate the effectiveness of MF 1% gel as an adjunct to scaling and root planing in the treatment of intrabony defects in patients with chronic periodontitis. The study comprised 65 individuals divided into two groups: 1% MF with SRP and placebo gel with SRP. Clinical parameters were evaluated at baseline, 3 months, and 6 months; they included plaque index, modified sulcus bleeding index, probing depth (PD), and clinical attachment level (CAL). Intrabony defect depth (IBD) was evaluated at the end of 6 months using computer-aided software. The mean PD reduction, CAL gain, and IBD depth reduction were found to be greater in the MF group than in the placebo group at all visits. The percentage of defect depth reduction was significantly greater in the MF group (26.8 ± 5.52%) than in the placebo sites (4.79 ± 2.30%, P < 0.001). One percent MF was found to significantly improve clinical and radiographic parameters in intrabony defects in patients with chronic periodontitis. © 2015 Wiley Publishing Asia Pty Ltd.

High levels of bacterial load have shown a deleterious influence on wound healing. Using antimicrobial dressings can control ulcers' bioburden. The aim of our study was to evaluate the improving of infected diabetic foot ulcers due an alginate's fiber and hydrocolloid silver dressing. We analysed a case series of 6 patients with diabetic foot ulcers without peripheral vascular disease and diagnosed from critical colonization and/or local infection according the presence of inflammation clinical signs. Patients were treated for a minimum period of two weeks. We analysed the percentage reduction in ulcer area from the day of enrolment to antimicrobial dressing removal. The duration of treatment had a median of 5 weeks with a minimum of 2 weeks and up to 6. The median percentage of area reduction of the wounds was 47.7% (range: 0.5%-90%). The mean percentage reduction on the lesion was 58% from 2 weeks and 67.14% at 3 weeks. All patients had reduced significantly their size at 3 weeks from beginning of treatment (p < 0.05). The use of an alginate's fiber and hydrocolloid silver dressing promotes healing on diabetic foot ulcers with local infection, reducing the inflammatory clinical signs significantly over a period of three weeks.

Atomoxetine and methylphenidate are widely used to treat attention-deficit-hyperactivity disorder (ADHD) with similar effectiveness after 8 weeks of treatment, when atomoxetine has reached its a full effect. Both drugs have also been shown to have an effect on comorbid anxiety. To the best of our knowledge, no study has compared their effect on the dynamics of anxiety symptom reduction. The aim of this study was to compare the medication effect on core and comorbid anxiety symptom dynamics in children with ADHD. Sixty-nine patients participated in the study: 36 patients were taking atomoxetine and 33 patients, methylphenidate. Therapeutic effect on core symptoms of ADHD was measured on the ADHD-rating scale IV, and symptoms of anxiety were measured using the Conners Parent Rating Scale (CPRS). Symptoms were measured prior to and every 2 weeks during 8 weeks of treatment. There was a significant decrease in CPRS anxiety subscale score in both medication groups. Anxiety subscale score was significantly lower in the atomoxetine group in the fourth week, and lasted through to 8 weeks of medication. Both atomoxetine and methylphenidate reduced the symptoms of ADHD and anxiety. Atomoxetine was more effective in anxiety symptom reduction from the fourth week of treatment. © 2015 Japan Pediatric Society.

Annual mass treatment with antifilarial drugs is the cornerstone of the global program to eliminate lymphatic filariasis (LF). Although the primary goal of the program is to interrupt transmission of LF, additional public health benefits also are expected because of the known anthelminthic properties of these drugs. Since rapid re-infection with intestinal helminths occurs following treatment, annual de-worming may not be sufficient to produce a lasting reduction in the prevalence and intensity of these infections. We conducted stool examinations in four sentinel communities before and approximately nine months after each of two rounds of mass drug administration (MDA) with diethylcarbamazine and albendazole in the context of an LF elimination program in Leogane, Haiti. At baseline, overall Ascaris, Trichuris, and hookworm infection prevalences were 20.9%, 34.0%, and 11.2%, respectively (n = 2,716 stools). Nine months after the second MDA, Ascaris, Trichuris and hookworm prevalences had decreased significantly, to 14.1%, 14.6%, and 2.0%, respectively (n = 814 stools). Infection intensity decreased significantly for all three parasites as well. These results demonstrate that substantial reductions in intestinal helminth infections are associated with mass treatment of filariasis in Haiti and are consistent with the conclusion that high levels of coverage for the LF program can decrease transmission of geohelminths.

The aim of this study was to perform a systematic review of the treatment of nasal bone fractures. The search terms ("nasal bone fracture" AND complication) and ("nasal bone fracture" AND [anosmia OR olfaction OR olfactory nerve OR smell]) and (anosmia AND ["nasal preparation" OR "nasal antiseptics"]) were used to search PubMed and SCOPUS. Of the 500 titles, 40 full papers were reviewed. One paper was excluded, and 3 mined papers were added. Ultimately, 12 papers were analyzed. The overall deformity rate was 10.4% ± 4.8%. No significant differences were found between patients who underwent closed reduction (14.7% ± 7.3%) and those who underwent open reduction (9.4% ± 4.4%), between those who underwent local anesthesia (5.8% ± 4.5%), and those who underwent general anesthesia (8.8% ± 3.8%), or between those who received timely treatment (5.7%) and those whose treatment was delayed (9.0%). Septal deviation occurred in 10.0% of patients as a sequela of nasal bone fracture. The nasal obstruction rate was 10.5% ± 5.3%. Fewer patients of nasal obstruction occurred in the open reduction patients (6.9% ± 4.4%) than in the closed reduction patients (15.2%). One patient of epiphora and 1 patient of diplopia were reportedAmong the 77 patients with nasal bone fractures, 29 (37.7% ± 11.3%) complained of olfactory disturbances. No significant associations were found between the type of fracture and the presence of olfactory disturbances. It is recommended for providers to explain to patients that approximately one-tenth of nasal bone fractures exhibit deformity, septal deviation, or nasal obstruction after surgery. Surgeons should take considerable care to avoid the olfactory mucosa during reduction surgery.

Aim: The aim of the study is to assess the efficacy of Calendula officinalis gel as cost-effective treatment modality in comparison to lycopene gel in the treatment of leukoplakia. Materials and Methods: The study comprised of sixty patients of clinically diagnosed and histopathologically confirmed cases of homogeneous leukoplakia which were divided into Group I and Group II with thirty patients each. Group I patients were dispensed C. officinalis extract gel whereas Group II patients were given lycopene gel. The therapy was instituted for 1 month to assess the change in the size of the lesion at the baseline and posttreatment. Results: The results revealed a statistically significant difference in both Group I and Group II when the pre- and post-treatment results were compared in the same group. The mean difference in the reduction in size before and after treatment for Group I was 2.0% ±1.0 cm while for the Group II, it was 1.57% ±0.87 cm. The intergroup comparison for the evaluation of reduction in the size of the lesion did not reveal statistically significant results. Conclusion: C. officinalis extract gel can be effectively used as an alternative to conventional treatment modality. PMID:28929051

To evaluate the safety and efficacy of dapsone gel 5% in the treatment of acne when used in combination with adapalene gel 0.1%, benzoyl peroxide gel 4% or moisturizer. This was a twelve-week, randomized, double-blind study. Patients aged 12 years and older (n=301) applied dapsone gel twice daily and were randomly assigned (1:1:1) to one of three additional treatments, applied once daily. By week 12, dapsone gel combined with any of the three additional treatments reduced the mean number of inflammatory lesions. However, the authors did not detect a significant difference in the reduction of inflammatory lesions when dapsone was used in combination with adapalene gel or with benzoyl peroxide gel compared to the dapsone plus moisturizer combination group (P=0.052 for both versus moisturizer combination). Patients treated with dapsone gel combined with adapalene showed a significantly better response in reduction in non-inflammatory and total acne lesion count than those who received the moisturizer combination. Local adverse reactions in all three treatment groups were minimal and generally mild in severity. Dapsone gel in combination with adapalene gel or benzoyl peroxide gel is safe and well tolerated for the treatment of acne vulgaris.

The objective of this observational study was to evaluate the efficacy of medical cannabis for the treatment of refractory epilepsy. Fifty-seven patients (age 1-20 years) with epilepsy of various etiologies were treated with Cannabis oil extract (CBD/THC ratio of 20:1) for at least 3 months (Median follow up time-18 months). Forty-Six Patients were included in the efficacy analysis. Average CBD dose was11.4 mg/kg/d. Twenty-six patients (56%) had ≤50% reduction in mean monthly seizure frequency. There was no statistically significant difference in response rate among various epilepsy etiologies, and cannabis strain used. Younger age at treatment onset (<10 years) and higher CBD dose (>11 mg/kg/d) were associated with better response to treatment. Adverse reactions were reported in 46% of patients and were the main reason for treatment cessation. Our results suggest that adding CBD-enriched cannabis extract to the treatment regimen of patients with refractory epilepsy may result in a significant reduction in seizure frequency according to parental reports. Randomized controlled trials are necessary to assess its true efficacy. Copyright © 2018 Elsevier B.V. All rights reserved.

Extracorporeal shockwave treatment (ESWT) and ultrasound-guided percutaneous lavage (UGPL) are two effective ways of treating rotator cuff calcific tendinopathy (RCCT). The aim of the present study was to compare the effectiveness of these techniques in the treatment of RCCT. Prospective, randomized, controlled trial. Patients treated in our sports medicine and rehabilitation center (Centro Médico Deyre, Madrid. Spain) between January 2007 and December 2013. This randomized study compares the results achieved with these techniques over one year following their use to treat the above condition. Eighty patients received ESWT and 121 received UGPL. A visual analogue scale was used to measure pain, and ultrasound to determine the extent of calcification, at 3, 6, and 12 months after treatment. Pain and the amount of calcification were significantly reduced by both techniques at 3, 6 and 12 months (P<0.001 for each), but significantly more so by UGPL (P<0.001). Both techniques are valid for the treatment of RCCT, although UGPL is associated with a greater reduction of calcification and greater reduction in pain. The results obtained applying UGPL, the low cost and the lack of complications should therefore make the treatment of choice in centers that are appropriately equipped and staffed.

We studied the efficacy of four different treatment regimens (sulphonylurea and metformin+/-acarbose versus glimepiride and rosiglitazone versus glimepiride and bedtime NPH insulin versus multiple actrapid and NPH insulin injections) in poorly controlled type 2 diabetes subjects on hs-CRP, VCAM-1 and AGE at 4, 8 and 12 weeks of treatment. Multiple insulin injections rapidly improved HbA(1c) by 0.6+/-0.9% (p<0.005), 1.2+/-1.3% (p<0.0005) and 1.3+/-1.4% (p<0.0005) at week 4, at week 8 and week 12, respectively. Subjects who continued their existing combination treatment of sulphonylurea, metformin+/-acarbose also showed a significant reduction in HbA(1c) (p<0.05). Although effective in reducing glycemic parameters, there was no reduction in CRP levels in either treatment group. The treatment regimen consisting of rosiglitazone and glimepiride significantly lowered hs-CRP by -2.6 (3.9) mg/L (p<0.05) at week 12 in spite of no improvement in blood glucose. AGE improved in all groups irrespective of type of treatment, glycaemic control and CRP levels. Our data indicate rapid glycaemic control alone does not necessarily result in improvement in markers of inflammation in type 2 diabetes patients.

While translational evidence suggests that long-chain omega-3 fatty acid status is positively associated with the efficacy of selective serotonin reuptake inhibitor drugs, the neurochemical mechanisms mediating this interaction are not known. Here, we investigated the effects of dietary omega-3 (n-3) fatty acid insufficiency on the neurochemical and behavioral effects of chronic fluoxetine (FLX) treatment. Female rats were fed diets with (CON, n=56) or without (DEF, n=40) the n-3 fatty acids during peri-adolescent development (P21-P90), and one half of each group was administered FLX (10mg/kg/day) for 30days (P60-P90) prior to testing. In adulthood (P90), regional brain serotonin (5-HT) and 5-hydroxyindoleacetic (5-HIAA) concentrations, presynaptic markers of 5-HT neurotransmission, behavioral responses in the forced swim test (FST), and plasma FLX and norfluoxetine (NFLX) concentrations were investigated. Peri-adolescent n-3 insufficiency led to significant reductions in cortical docosahexaenoic acid (DHA, 22:6n-3) composition in DEF (-25%, p≤0.0001) and DEF+FLX (-28%, p≤0.0001) rats. Untreated DEF rats exhibited significantly lower regional 5-HIAA/5-HT ratios compared with untreated CON rats, but exhibited similar behavioral responses in the FST. In both CON and DEF rats, chronic FLX treatment similarly and significantly decreased 5-HIAA concentrations and the 5-HIAA/5-HT ratio in the hypothalamus, hippocampus, and nucleus accumbens, brainstem tryptophan hydroxylase-2 mRNA expression, and immobility in the FST. While the FLX-induced reduction in 5-HIAA concentrations in the prefrontal cortex was significantly blunted in DEF rats, the reduction in the 5-HIAA/5-HT ratio was similar to CON rats. Although plasma FLX and NFLX levels were not significantly different in DEF and CON rats, the NFLX/FLX ratio was significantly lower in DEF+FLX rats. These preclinical data demonstrate that n-3 fatty acid deficiency does not significantly reduce the effects of chronic FLX treatment on central 5-HT turnover or behavior in the FST in female rats. © 2013 Elsevier Inc.

Background Hepatitis C (HCV) is a significant public health problem that primarily affects current and former substance users. However, individuals with a history of substance use are less likely to have access to or engage in HCV care. Psychological and behavioral barriers prevent many HCV-infected individuals from initiating or engaging in HCV treatment. This study aimed to investigate the psychological and behavioral experiences of current and former substance users receiving HCV treatment within a combined methadone and primary care clinic in the United States. Methods We conducted 31 semi-structured qualitative interviews with opioid-dependent adults enrolled in an integrated HCV treatment program within a methadone maintenance clinic in the Bronx, NY. We used thematic analysis, informed by grounded theory, and inquired about perceptions of HCV before and after initiating HCV treatment, reasons for initiating HCV treatment, and the decision to participate in individual versus group HCV treatment. Results Participants described psychological and behavioral transformation over the course of HCV treatment. These included reductions in internalized stigma and shame related to HCV and addiction, increases in HCV disclosure and self-care, reductions in substance use, and new desire to help others who are living with HCV. Conclusions Integrating HCV treatment with methadone maintenance has the potential to create psychological and behavioral transformations among substance using adults, including reductions in HCV- and addiction-related shame and improvements in overall self-care.

To introduce a novel distraction technique for the treatment of basilar invagination (BI) and atlantoaxial dislocation (AAD) via a posterior-only approach. Twenty-one consecutive patients with BI and AAD who underwent posterior distraction reduction and occipitocervical fixation between January 2009 and June 2013 were enrolled in the present study. This novel distraction technique included two steps. First, the distraction between the occipitocervical junction of the rod (OCJR) and the occipital screws was performed to achieve horizontal and partial vertical reduction. Secondly, the distraction was performed between the C2 screws and OCJR to achieve complete vertical reduction. The pre- and postoperative JOA score, the extent of reduction, the fusion status, and the complications were recorded and analyzed. The mean follow-up was 18.3 months with a range of 10-32 months. No patient incurred neurovascular injury during surgery. The mean JOA score at the last follow-up (15.4) showed significant improvement (P<0.01) compared with the pre-operative parameters (11.2). Complete horizontal reduction was achieved in 18 patients (85.7%), and complete vertical reduction was achieved in 17 patients (80.9%). The rest patients are all received greater than 50% horizontal and vertical reduction. Solid fusion was achieved in 20 patients (95.2%). Mild dysphagia was observed in two patients. One patient suffered from postoperative fever and pulmonary infection. This novel distraction technique may provide satisfactory reduction via a posterior-only approach without exposure of the C1/2 facet joint. Therefore, it is a safe and effective method for the treatment of BI with AAD. Copyright © 2015 Elsevier B.V. All rights reserved.

This treatment-development study is a Stage I evaluation of an intervention that combines mindfulness meditation with cognitive-behavior therapy for insomnia (CBT-I). Thirty adults who met research diagnostic criteria for Psychophysiological Insomnia (Edinger et al., 2004) participated in a 6-week, multi-component group intervention using mindfulness meditation, sleep restriction, stimulus control, sleep education, and sleep hygiene. Sleep diaries and self-reported pre-sleep arousal were assessed weekly while secondary measures of insomnia severity, arousal, mindfulness skills, and daytime functioning were assessed at pre-treatment and post-treatment. Data collected on recruitment, retention, compliance, and satisfaction indicate that the treatment protocol is feasible to deliver and is acceptable for individuals seeking treatment for insomnia. The overall patterns of change with treatment demonstrated statistically and clinically significant improvements in several nighttime symptoms of insomnia as well as statistically significant reductions in pre-sleep arousal, sleep effort, and dysfunctional sleep-related cognitions. In addition, a significant correlation was found between the number of meditation sessions and changes on a trait measure of arousal. Together, the findings indicate that mindfulness meditation can be combined with CBT-I and this integrated intervention is associated with reductions in both sleep and sleep-related arousal. Further testing of this intervention using randomized controlled trials is warranted to evaluate the efficacy of the intervention for this population and the specific effects of each component on sleep and both psychological and physiological arousal.
