Tinea versicolor (TV) is characterised by the appearance of maculosquamous lesions sometimes associated with mild erythema and pruritus in characteristic areas of the body. Eberconazole and terbinafine though drugs of different classes provide both mycological and clinical cure. This study aims to compare the efficacy and safety of eberconazole versus terbinafine in patients of TV. An open-label, randomised, comparative clinical trial was conducted on 60 patients. The patients were randomly divided into two study groups. Group A: Eberconazole 1% cream once daily and Group B: Terbinafine 1% cream once daily for 2 weeks. Efficacy assessment was done by observing signs and symptoms, i.e., Physician assessment 4-point scale, microscopic KOH examination, Wood's lamp examination, global clinical response assessment, and patient's assessment on visual analog scale at the end of 2 weeks and subsequently patients were reassessed at the end of 4 and 8 weeks to check any relapse. Safety assessment was also done. There was a significant improvement in all the parameters in both groups over a period of 2 weeks. Both the treatment groups, i.e., eberconazole and terbinafine were found to be safe and efficacious at the end of 2 weeks, and no statistically significant difference was observed between the two groups regarding complete cure, i.e., mycological and clinical cure (80% vs. 63.33%), respectively. However, early response (at the end of week 1) was observed with eberconazole. No relapse was seen with eberconazole, but one patient had relapse at 8 weeks with terbinafine. Both drugs had similar safety profile. Although both the drugs cured the disease, eberconazole showed better response as clinical cure and mycological cure were observed earlier and no patient relapsed in the follow-up.

The aim of this review was to assess the clinical relevance of the relative antidepressant efficacy of escitalopram and citalopram by meta-analysis. Studies in major depressive disorder (MDD) with both escitalopram and citalopram treatment arms were identified. Adult patients had to meet DSM-IV criteria for MDD. The primary outcome measure was the treatment difference in Montgomery-Asberg Depression Rating Scale (MADRS) total score at week 8 (or last assessment if escitalopram, n=995; citalopram, n=1014). Escitalopram was significantly more effective than citalopram in overall treatment effect, with an estimated mean treatment difference of 1.7 points at week 8 (or last assessment if escitalopram. In this meta-analysis, the statistically significant superior efficacy of escitalopram compared to citalopram was shown to be clinically relevant.

Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients) and conventional treatment group (30 patients). An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months). Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6) and 32.6 (±12.7) years, respectively (P = 0.45). After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80), frequency of migraine attacks (P = 0.63) and duration of attacks per hours (P = 0.48) were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care.

In this prospective study, we compared the efficacy and side effects of indomethacin, ibuprofen, and paracetamol in patent ductus arteriosus (PDA) closure in preterm neonates. Three hundred preterm neonates with hemodynamically significant PDA (hs-PDA) admitted at our neonatal intensive care unit were enrolled in the study. They were randomized into three groups. Group I (paracetamol group) received 15 mg/kg/6 h IV paracetamol infusion for 3 days. Group II (ibuprofen group) received 10 mg/kg IV ibuprofen infusion followed by 5 mg/kg/day for 2 days. Group III (indomethacin group) received 0.2 mg/kg/12 h indomethacin IV infusion for three doses. Laboratory investigations such as renal function test, liver function test, complete blood count, and blood gases were conducted in addition to echocardiographic examinations. All investigations were done before and 3 days after treatment. There was no significant difference between all groups regarding efficacy of PDA closure (P = 0.868). There was a significant increase in serum creatinine levels and serum blood urea nitrogen (BUN) in the ibuprofen and indomethacin groups (P  0.05). Ventilatory settings improved significantly in patients with successful closure of PDA than those with failed PDA closure (P closure of PDA in preterm neonates and has less side effects mainly on renal function, platelet count, and GIT bleeding. What is Known: • Hemodynamically significant patent ductus arteriosus has many complications for preterm and low birth weight neonates and better to be closed. Many drugs were used for medical closure of PDA e.g. indomethacin, ibuprofen and recently paracetamol. Many studies compare safety and efficacy of paracetamol with either indomethacin or ibuprofen. What is New: • It is the first large study that compares the efficacy and side effects of the three drugs in one study.

The demand for cataract surgery is rising, calling for pathways that have good access and are cost-effective. Lean thinking is a management strategy, aimed at improving quality while reducing costs. Lean production processes are designed to identify gaps between expected and actual performance. To analyse the efficacy and efficiency of a lean cataract pathway. Lean care delivered to a prospective cohort (616 cataract patients) was compared (1) with traditional care delivered to a historical cohort (591 cataract patients) and (2) with expected lean care in the prospective cohort. To evaluate efficacy, the authors analysed how many patients received care that adhered to the lean pathway's specifications. To evaluate efficiency, the authors analysed how often patients visited the hospital and how many additional patients could access the pathway. In the lean pathway, patient visits decreased by 23%, and access to the cataract pathway increased with 42%. A 40% decrease in patient visits and a 76% increase in access could have been realised if healthcare staff would have adhered to the lean pathway's specifications. Lean pathways can realise large improvements, and still have a significant gap between expected and actual care delivery. The challenge for healthcare teams is not to improve care delivery by using lean pathways as opposed to using traditional pathways, but to strive for optimal performance by consistently adhering to the specifications of the lean pathway.

Benign prostatic hyperplasia (BPH) is a common and progressive disease affecting elderly males, often associated with lower urinary tract symptoms (LUTS). α1-blockers are the mainstay in symptomatic therapy of BPH. Because of their greater uroselectivity and minimal hemodynamic effects, alfuzosin, tamsulosin, and silodosin are generally preferred. The aim of this study was to compare the efficacy and tolerability of alfuzosin, tamsulosin, and silodosin in patients with BPH and LUTS. Ninety subjects with BPH and LUTS were randomized into three groups of thirty in each, to receive alfuzosin sustained release (SR) 10 mg, tamsulosin 0.4 mg, or silodosin 8 mg for 12 weeks. The primary outcome measure was a change in the International Prostate Symptom Score (IPSS), and the secondary outcome measures were changes in individual subjective symptom scores, quality of life score (QLS), and peak flow rate (Qmax) from baseline. The treatment response was monitored at 2, 4, 8, and 12 weeks. IPSS improved by 88.18%, 72.12%, and 82.23% in alfuzosin SR, tamsulosin and silodosin groups (P 75% in all the three groups (P tamsulosin (P = 0.025 and P tamsulosin (three subjects). Alfuzosin, tamsulosin, and silodosin showed similar efficacy in improvement of LUTS secondary to BPH, with good tolerability, acceptability, and minimum hemodynamic adverse effects. Alfuzosin, tamsulosin, and silodosin are comparable in efficacy in symptomatic management of BPH. The occurrence of QTc prolongation in three subjects with tamsulosin in the present study is an unexpected adverse event as there are no reports of QTc prolongation with tamsulosin in any of the previous studies.

This study aimed to retrospectively evaluate the efficacy and safety of preoperative transcatheter arterial embolization (pTAE) for treating nasopharyngeal angiofibroma (NPAF). Seventy-four NPAF patients were hospitalized for elective surgical treatment with pTAE (pTAE group, n = 32) or surgical treatment alone (non-pTAE group, n = 42) between January 1990 and December 2013. The following outcome measures were retrospectively analyzed and compared: intraoperative bleeding volume, surgery time (ST), duration of postoperative hospital stay (PHS), and disease recurrence. Among Radkowski stage I patients, those in pTAE group had a slightly higher but not significant bleeding volume than patients in non-pTAE group (344 ± 407 vs. 248 ± 219 mL, P = 0.899); among stage II/III patients, however, patients in pTAE group showed a significantly lower bleeding volume than patients in non-pTAE group (stage II, 829 ± 519 vs. 1339 ± 767 mL, P = 0.035; stage III, 1267 ± 592 vs. 2125  ± 479 mL, P = 0.024). The two groups presented comparable OTs, PHSs, and rates of frontal recurrence (all P>0.05). pTAE significantly reduces intraoperative bleeding in NPAF patients with Radkowski stage II/III disease, but offers no additional benefits regarding ST, PHS, or recurrence.

Prokinetic agents like itopride hydrochloride and mosapride citrate are commonly used in the management of functional dyspepsia. However, in a recently conducted international, multicentric study, efficacy of 3 different regimens of mosapride was shown to be comparable to placebo. The objective of this phase 4 randomised, double blind, prospective study was to compare the efficacy and safety of ganaton (itopride hydrochloride) and mosapride citrate in the management of functional dyspepsia among patients attending the gastroenterology outpatient department of a tertiary care hospital. Ganaton 50 mg or mosapride citrate 5 mg three times daily before meals for a period of 2 weeks was administered orally. Thirty functional dyspepsia patients in each group (total = 60) were randomised to receive itopride hydrochloride or mosapride citrate treatment for 2 weeks. In itopride versus mosapride groups, global efficacy as judged by patients was excellent in 17 versus 9 (p itopride versus mosapride group global efficacy as judged by physician was excellent in 24 (80%) versus 15 (50%) and poor in 0 (0%) versus 3 (10%) patients respectively. The global efficacy was rated as excellent to good in significantly (p itopride (93.3%) group as compared to mosapride (63.33 %) group. None of the patients reported any adverse events with itopride treatment. In the mosapride group 5 patients (16.7%) reported adverse events. Two patients (6.7%) were withdrawn from mosapride treatment due to adverse events. The physician rated global tolerability ofitopride versus mosapride treatment as excellent in 23 (76.7%) versus 8 (26.7%) (p itopride hydrochloride) is superior in efficacy and safety over mosapride citrate in the management of functional dyspepsia.

SUMMARY The aim of the present study was to find out efficacy of frontalis EMG Biofeedback therapy, deep muscular relaxation therapy and compare the efficacy of both in cases of tension headache. During two week basal-data recording period all patients were taught deep muscular relaxation by Jacobson′s technique. Simultaneously patients were instructed to keep headache diary. Headache diary yielded three different parameters a) number of headache-free days per week, b) peak headache intensity (or each week and c) average daily headache activity score per week. These parameters were used to find out therapeutic efficacy of each treatment. Patients were randomly divided in two groups. EMG Biofeedback group was given frontalis EMG feedback through EMG J 33 muscle trainer of Cyborg Corporation (U.S.A.). Patients in each group were given 20 sessions (two sessions per week); each session lasting 30 minutes. Patients were instructed to practice at least one 30 minute session of relaxation at home. The data were subjected to statistical calculation. The results indicate that frontalis EMG Biofeedback therapy and deep muscle relaxation therapy are significantly effective in cases of tension headache. Both treatments are equally effective. The findings are discussed in relation to Indian situation. PMID:21965970

Anticonvulsants and antidepressants are mostly used in management of painful diabetic neuropathy (PDN). However there are few direct comparisons between drugs of these classes, making evidence-based decision-making in the treatment of painful diabetic neuropathy difficult. This study aimed to perform a network meta-analysis and benefit-risk analysis to evaluate the comparative efficacy and safety of these drugs in PDN treatment. Comparative effectiveness study. Medical Education and Research facility in India. A comprehensive data search was done in PubMed, Cochrane, and Embase up to August 2012. We then systematically reviewed the studies which compared any of 6 drugs for the management of PDN: amitriptyline, duloxetine, gabapentin, pregabalin, valproate, and venlafaxine or any of their combinations. We performed a random-effects network meta-analysis to rank treatments in terms of efficacy and safety. We chose the number of patients experiencing = 50% reduction in pain and number of patient withdrawals due to adverse events (AE) as primary outcomes for efficacy and safety, respectively. We also performed benefit-risk analysis, taking efficacy outcome as benefit and safety outcome as risk. Analysis was intention-to-treat. We included 21 published trials in the analysis. Duloxetine, gabapentin, pregabalin, and venlafaxine were shown to be significantly efficacious compared to placebo with odds ratios (OR) of 2.12, 3.98, 2.78, and 4.43, respectively. Amitriptyline (OR: 7.03, 95% confidence interval [CI]: 1.87, 29.05) and duloxetine (OR: 3.26, 95% CI: 1.04, 9.97) caused more withdrawals than gabapentin. The ranking order of efficacy was gabapentin, venlafaxine, pregabalin, duloxetine/gabapentin, duloxetine, amitriptyline, and placebo and the ranking order of safety was placebo, gabapentin, pregabalin, venlafaxine, duloxetine/gabapentin combination, duloxetine, and amitriptyline. Benefit-risk balance favored the order: gabapentin, venlafaxine, pregabalin, duloxetine

Is the efficacy of psychopharmacological drugs comparable to the efficacy of general medicine medication?

Seemüller Florian

2012-02-01

Full Text Available Abstract There is an ongoing debate concerning the risk benefit ratio of psychopharmacologic compounds. With respect to the benefit, recent reports and meta-analyses note only small effect sizes with comparably high placebo response rates in the psychiatric field. These reports together with others lead to a wider, general critique on psychotropic drugs in the scientific community and in the lay press. In a recently published article, Leucht and his colleagues compare the efficacy of psychotropic drugs with the efficacy of common general medicine drugs in different indications according to results from reviewed meta-analyses. The authors conclude that, overall, the psychiatric drugs were generally not less effective than most other medical drugs. This article will highlight some of the results of this systematic review and discuss the limitations and the impact of this important approach on the above mentioned debate.

Full Text Available Abstract Background A combination of artesunate (AS plus sulphadoxine/pyrimethamine (SP as first-line and artemether-lumefantrine (AL as second-line treatment are currently recommended against uncomplicated P. falciparum infection in Sudan. However, there is limited information on the efficacy of ACTs in the country and only one report of PCR-corrected results for AS/SP only. Methods The WHO protocol for the assessment of antimalarial drug efficacy for the treatment of uncomplicated falciparum malaria was employed. Artesunate plus sulphadoxine/pyrimethamine (AS/SP was compared to artemether-lumefantrine (AL in a 28-day follow up. Samples that were classified as early treatment failure (ETF, late treatment failure (LCF or late parasitological failure (LPF were genotyped for msp-1 and msp-2 genes to differentiate recrudescence from reinfection. Results A total of 178 patients were screened and 160 met the enrolment criteria and were recruited to the study of which 157 (98.1% completed the follow up and had an analysed treatment outcome. On the AS/SP arm, three (0.038% patients were lost during the follow-up, two on day 1 and one on day 7, and 77 (96.3 completed the study, while all 80 (100% patients completed the follow up in the AL arm. In the per protocol analysis for AS/SP the treatment outcome for patients who completed the follow-up were as follows: adequate clinical and parasitological response (ACPR; 84.4% ETF; 1.3%, LCF; 3.9%, (LPF; 10.4%. For the AL arm the out come was as follows, ACPR; 90%, ETF; 0%, LCF; 6.3% and LPF; 3.8%. However, when PCR-corrected, 6.5% (5/77 of patients treated with AS/SP maintained parasites from their primary infection, while (7/80 in the AL group maintained their initial parasite genotype. Therefore, PCR-corrected efficacy was 93.5% in the AS/SP treated group and for AL it was 91.3%. Conclusion Both AS/SP and AL are highly effective for the treatment of uncomplicated falciparum malaria in eastern Sudan. However

Purpose The aim of this study was to evaluate the safety, tolerability, and efficacy of a low-dose version of bromfenac 0.075% in DuraSite® (bromfenac 0.075%) compared with DuraSite® vehicle (vehicle) alone for the treatment of postoperative inflammation and ocular pain after cataract surgery. Methods A multicenter, double-masked, vehicle-controlled, parallel-group clinical trial of 240 subjects randomized in a 2:1 ratio to bromfenac 0.075% or vehicle was conducted. Subjects were dosed BID beginning 1 day before the cataract surgery, the day of surgery, and 14 days after surgery. A slit lamp biomicroscopy examination was performed to evaluate the signs of inflammation, including anterior chamber cells (ACC) and anterior chamber flare (ACF). The primary efficacy variable was the proportion of subjects with an ACC grade of 0 at Day 15. Secondary efficacy endpoints included the proportion of subjects who achieved a pain score of 0 at each postsurgical visual analog scale (VAS) assessment and the proportion of subjects with an ACF grade of 0 at Day 15. Results At Day 15, proportionally more subjects in the bromfenac 0.075% group than in the vehicle group had an ACC grade of 0 (57.1% vs 18.8%, respectively; P<0.001). At each of the postsurgical time points (Days 1, 8, 15, and 29), proportionally more bromfenac 0.075%-treated subjects (76.8%, 90.5%, 92.9%, and 85.1%, respectively) had no pain (a VAS score of 0) compared with the vehicle-treated subjects (48.2%, 38.8%, 42.4%, and 47.1%, respectively), and at each time point, these differences in proportions were statistically significant (P<0.001). More subjects in the bromfenac 0.075% group had complete ACF resolution (151/167; 90.4%) compared to those in the vehicle group (54/85; 63.5%). There were no new safety signals reported. Conclusion Bromfenac 0.075% in DuraSite is safe, well tolerated, and effective at reducing inflammation and preventing pain associated with cataract surgery. PMID:27920490

Tonsillectomy has recently been suggested as an effective treatment for PFAPA syndrome but little is known about its long-term efficacy. We compared the clinical features and the long-term outcome of a large cohort of patients with PFAPA syndrome treated with tonsillectomy or with standard medical treatment. We conducted a retrospective study on patients with PFAPA syndrome followed at a tertiary care centre from January 1993 to August 2010. Clinical characteristics and laboratory parameters were evaluated at onset and during the follow-up. Disease outcomes of patients who underwent tonsillectomy and of those treated with medical therapy (NSAIDs, prednisone) were compared. Clinical remission on medication (CRM) was considered the persistence of fever attacks which were well controlled by medical therapy, clinical remission (CR) was defined as the absence of fever attacks, without any treatment, for more than 12 months. 275 patients with PFAPA syndrome, 59.6% males, aged 27.9 months at onset and followed for mean 54.5 months, entered the study. CR was reported in 59.6% of the patients and was significantly less frequent in those with positive family history for PFAPA (46.4% vs. 66.1%, p=0.003). 27/41 patients (65.9%), responded to tonsillectomy and this result was comparable with that observed in those treated with medical therapy (59.1%, p=0.51). Disease duration, age at remission or presence of associated symptoms were not significantly different in both groups. No predictors of tonsillectomy failure were found. In a large cohort of patients with PFAPA syndrome, tonsillectomy efficacy was comparable to the standard medical treatment.

The in vivo efficacy of terbinafine was compared to lanoconazole and luliconazole in the topical treatment of dermatophytosis caused by Trichophyton mentagrophytes using a guinea pig model. Topical antifungal treatment commenced three days post-infection, and each agent was applied once daily for seven consecutive days. Upon completion of the treatment period, evaluations of clinical and mycological efficacies were performed, as was scanning electron microscopy (SEM) analyses. Data showed that while all tested antifungals demonstrated significant mycological efficacy in terms of eradicating the fungi over untreated control, terbinafine and luliconazole showed superior clinical efficacy compared to lanoconazole (P-values Terbinafine demonstrated the highest clinical percent efficacy. SEM analysis revealed hairs from terbinafine and lanoconazole-treated animals had near complete clearance of fungi, while samples from luliconazole-treated animals were covered with debris and few conidia. This study demonstrates that, in general, terbinafine possessed similar efficacy to lanoconazole and luliconazole in the treatment of dermatophytosis. Terbinafine tended to have superior clinical efficacy compared to the azoles tested, although this difference was not statistically significant against luliconazole. This apparent superiority may be due to the fungicidal activity of terbinafine compared to the fungistatic effect of the other two drugs.

This comparative study of young adults in an established democracy (America) and transitional democracy (Hong Kong) analyzed the impact of political efficacy on the relationship between Internet/Facebook use on political and civic participation. Regression analyses in both samples showed that Facebook use consistently predicted both types of participation. Moreover, there were significant negative interaction effects of political efficacy and Facebook use on participation, such that the relationship between Facebook use and participation was stronger for those with lower levels of political efficacy. The findings provide cross-cultural support for the argument that social media use among youth can facilitate greater political and civic engagement, particularly for those who perceive that they have limited ability to participate and understand political affairs.

Studies have shown that people with multiple sclerosis (MS) report low levels of self-efficacy and self-esteem, high levels of anxiety and depression and reduced quality of life. The study aims to assess self-esteem, self-efficacy, mood and quality of life in young adults with MS and to compare them to a healthy control group. The age range for inclusion in the study was between 18 and 35years of age for both groups. Subjects with MS were recruited through the Italian MS Society. Healthy controls were recruited through social media and from a university undergraduate program. Subjects completed an anonymous online questionnaire combining various scales. Group differences on demographic data were assessed using parametric and non-parametric tests. Analyses of covariance (ANCOVA) were performed to evaluate differences between the two groups on scales of self-perception, mood and quality of life, adjusting for potentially confounding factors. Eighty-nine subjects with MS and 109 HC were included in the analysis. ANCOVA failed to demonstrate statistically significant differences between groups on self-esteem (F=0.11, p=0.743), self-efficacy (F=2.22, p=0.138), mood (anxiety F=0.03, p=0.855; depression F=0.06, p=0.812) and quality of life (F=0.08, p=0.772). This study demonstrated that young adults with MS and healthy controls have similar levels of self-esteem and self-efficacy and that they do not differ significantly on measures of mood and quality of life, as previously reported.

To compare the efficacy of 3 treatment options in patients with chronic blepharitis. An experimental, randomized, controlled study was conducted on 45 patients (female 67%; Mean age: 40.5 years) diagnosed with chronic blepharitis, in order to compare the effectiveness of three treatment options. Group 1: eyelid hygiene with neutral shampoo three times/day; group 2: neutral shampoo eyelid hygiene plus topical metronidazole gel 0.75% twice/day; group 3: neutral eyelid hygiene with shampoo plus neomycin 3.5% and polymyxin 10% antibiotic ointment with 0.5% dexamethasone 3 times/day. The symptoms and signs were assessed by assigning scores from 0: no symptoms and/or signs; 1: mild symptoms and/or signs, 2: moderate symptoms and/or signs; and 3: severe symptoms and/or signs. A significant improvement was observed in the signs and symptoms in all 3 treatment groups. While groups 1 and 2 had more improvement in all variables studied (P<.05), Group 3 showed no clinical improvement for itching (P=.16), dry eye (P=.29), eyelashes falling (P=.16), and erythema at the eyelid margin (P=.29). Shampoo eyelid hygiene neutral and neutral shampoo combined with the use of metronidazole gel reported better hygiene results than neutral shampoo lid with antibiotic ointment and neomycin and polymyxin dexamethasone.

Intensive exposure to insecticides has resulted in the evolution of insecticide resistance in the mosquitoes. We tested the bio-efficacy of two Culex quinquefasciatus Say (Diptera: Culicidae) laboratory strains differentially bio-responsive to pyrethroids to understand the comparative efficacy of different polyfluorobenzyle and conventional pyrethroid molecules and the role of piperonyl butoxide (PBO) in synergizing these molecules in increased tolerance of mosquitoes to these molecules. We have taken deltamethrin (α-cyano pyrethroid with phenoxybenzyl moiety); permethrin (phenoxybenzyl pyrethroid without an α-cyano group); transfluthrin, dimefluthrin, metofluthrin, and meperfluthrin (polyfluorinated benzyl compounds); and prallethrin (modified cyclopentadienone compound) for this study. We found higher bio-efficacy in dimefluthrin, metofluthrin, and meperfluthrin compared with transfluthrin against tested mosquito strains. We found that transfluthrin exhibited synergism with PBO, which supports the hypothesis that P450 enzymes could play a role in the detoxification process of transfluthrin, which was earlier not believed. However, other polyfluorobenzyl pyrethroids with a 4-(methoxymethyl) phenyl capping in the tetrafluorobenzyl ring (dimefluthrin, metofluthrin, and meperfluthrin) exhibit greater synergism with PBO compared with transfluthrin. Further study is required to understand the mechanism for higher synergistic ratios in polyfluorobenzyl pyrethroids with 4-(methoxymethyl) phenyl moiety and ascertain the possible involvement of novel mechanisms that may involve in developing resistance. This is the first report of comparative bio-efficacy of multiple polyfluorobenzyl pyrethroids and PBO synergism against mosquitoes.

Objective To compare the safety and efficacy of hysteroscopic sterilization with the “Essure” device with laparoscopic sterilization in a large, all-inclusive, state cohort. Design Population based cohort study. Settings Outpatient interventional setting in New York State. Participants Women undergoing interval sterilization procedure, including hysteroscopic sterilization with Essure device and laparoscopic surgery, between 2005 and 2013. Main outcomes measures Safety events within 30 days of procedures; unintended pregnancies and reoperations within one year of procedures. Mixed model accounting for hospital clustering was used to compare 30 day and 1 year outcomes, adjusting for patient characteristics and other confounders. Time to reoperation was evaluated using frailty model for time to event analysis. Results We identified 8048 patients undergoing hysteroscopic sterilization and 44 278 undergoing laparoscopic sterilization between 2005 and 2013 in New York State. There was a significant increase in the use of hysteroscopic procedures during this period, while use of laparoscopic sterilization decreased. Patients undergoing hysteroscopic sterilization were older than those undergoing laparoscopic sterilization and were more likely to have a history of pelvic inflammatory disease (10.3% v 7.2%, P<0.01), major abdominal surgery (9.4% v 7.9%, P<0.01), and cesarean section (23.2% v 15.4%, P<0.01). At one year after surgery, hysteroscopic sterilization was not associated with a higher risk of unintended pregnancy (odds ratio 0.84 (95% CI 0.63 to 1.12)) but was associated with a substantially increased risk of reoperation (odds ratio 10.16 (7.47 to 13.81)) compared with laparoscopic sterilization. Conclusions Patients undergoing hysteroscopic sterilization have a similar risk of unintended pregnancy but a more than 10-fold higher risk of undergoing reoperation compared with patients undergoing laparoscopic sterilization. Benefits and risks of both procedures

Clinical education is vital to both the development of clinical self-efficacy and the integration of future nurses into health care teams. The dedicated education unit clinical teaching model is an innovative clinical partnership, which promotes skill development, professional growth, clinical self-efficacy, and integration as a team member. Blended clinical teaching models are combining features of the dedicated education unit and traditional clinical model. The aims of this study are to explore how each of three clinical teaching models (dedicated education unit, blended, traditional) affects clinical self-efficacy and attitude toward team process, and to compare the dedicated education unit model and blended model to traditional clinical. A nonequivalent control-group quasi-experimental design was utilized. The convenience sample of 272 entry-level baccalaureate nursing students included 84 students participating in a dedicated education unit model treatment group, 66 students participating in a blended model treatment group, and 122 students participating in a traditional model control group. Perceived clinical self-efficacy was evaluated by the pretest/posttest scores obtained on the General Self-Efficacy scale. Attitude toward team process was evaluated by the pretest/posttest scores obtained on the TeamSTEPPS® Teamwork Attitude Questionnaire. All three clinical teaching models resulted in significant increases in both clinical self-efficacy (p=0.04) and attitude toward team process (p=0.003).

Lateral elbow pain is common with a population prevalence of 1%-3%. The study was a comparative trial to validate the efficacy of single injection of platelet-rich plasma (PRP) for tennis elbow as compared with single injections of triamcinolone and placebo (normal saline) over a short term period. Comparative trial with 3- and 6-month followup evaluated with visual analog scale (VAS) and facial pain scale (FPS). Our study included a total of eighty patients with unilateral or bilateral tennis elbows. The study population included patients between 20 and 40 years age group belonging to either sex with seventy unilateral and ten bilateral affections for more than 3-month duration. Patients suffering from elbow pain due to other problems or those who have received any form of injection were excluded from the study. One milliliter of 2% Xylocaine injection was given before injecting the proposed formulation under trial. VAS and FPS were used for scoring pain. Kruskal-Wallis test and Mann-Whitney U-tests were used for statistical analyses at 12 and 24 weeks. Overall, 49 females and 31 males were included with thirty elbows in each group. Both the PRP and triamcinolone groups had better pain relief at 3 and 6 months as compared to normal saline group ( P < 0.05), but at 6 months followup, the PRP group had statistically significant better pain relief than triamcinolone group. In the triamcinolone group, 13 patients had injection site hypopigmentation and 3 patients had subdermal atrophy. Over a short term period, PRP gives better pain relief than triamcinolone or normal saline in tennis elbow which needs to be validated over long term period by further studies.

Conclusion: Nafarelin and danazol demonstrated similar clinical efficacy, but nafarelin was associated with fewer laboratory changes and a stable lipid profile, relative to danazol. Moreover, intranasally administered nafarelin is noninvasive, and may be a more comfortable and safer alternative to slow-release injectable GnRH agonists. Based on this study, we suggest that nafarelin, like other GnRH analogues, may be a treatment of choice for Taiwanese women with endometriosis. However, direct comparative studies of nafarelin with slow-release injectable GnRH agonists are now required.

To treat functional constipation, both electroacupuncture (EA) therapy and transcutaneous electric nerve stimulation (TENS) are safe and effective. However, no head-to-head comparison trial has been conducted. This trial compares the efficacy of electroacupuncture relative to transcutaneous electric nerve stimulation for functional constipation. Individuals with functional constipation will be randomly allocated to receive either EA or TENS (n = 51, each), 3 times per week for 8 weeks. The primary outcome is the percentage of participants with an average increase from baseline of 1 or more complete spontaneous bowel movements at week 8. The secondary outcome measures are the following: at the time of visits, changes in the number of complete spontaneous bowel movements, number of spontaneous bowel movements, stool character, difficulty in defecation, patients' assessment of quality of life regarding constipation (self-report questionnaire), and use of auxiliary defecation methods. The results of this trial should verify whether EA is more efficacious than TENS for relieving symptoms of functional constipation. The major limitation of the study is the lack of blinding of the participants and acupuncturist.

The monoamine oxidase B inhibitors selegiline and rasagiline have not been compared in head-to-head clinical trials in patients with early Parkinson's disease.  The aim of this review was to compare the efficacy of these two agents in this setting. Randomized, placebo-controlled trials with an endpoint of the mean change from baseline in the Unified Parkinson's Disease Rating Scale (UPDRS) total score were included. Analysis included calculation of the standardized mean differences (SMDs) with 95% confidence intervals (CIs) and Forest Plot analyses for comparisons of pooled results. Five studies with selegiline (n = 1029) and four with rasagiline (n = 820) were included. Treatment duration was 2.5-9 months. Both selegiline and rasagiline showed significant SMDs versus placebo (-0.690, 95% CI -0.811, -0.569 and -1.025, 95% CI -1.230, -0.820; respectively), indicating a significant effect of both drugs on UPDRS. The SMD between selegiline and rasagiline was not significantly different (SMD 0.079; 95% CI -0.010, +0.167). It appears that selegiline and rasagiline have comparable efficacy in improving Parkinsonian symptoms in patients with early stage disease.

To compare efficacy, side effects, patient compliance, and preference between two types of custom-made mandibular advancement appliances (MAAs) in the treatment of patients with mild to moderate obstructive sleep apnea (OSA). This prospective, randomized, crossover study of 12 patients with mild to moderate OSA compared a titratable and a non-titratable MAA. Each patient was fitted with both appliances in a random order with a washout period of two weeks. Efficacy, side effects, compliance, and preference were evaluated by a questionnaire. All patients underwent overnight home sleep recordings prior to and after the use of each appliance in order to objectively assess sleep quality in terms of the apnea and hypopnea index (AHI), snoring frequency and oxygen desaturation index. Treatment successes (relief of symptoms and/or reduction of AHI to appliances. No compliance failure was reported, and in most patients, the side effects were mild, and improved with time. Both types of oral appliances were effective treatments for patients with mild to moderate OSA, with fewer side effects and higher patient satisfaction.

The effect of proton pump inhibitors (PPI) in Asian functional dyspepsia (FD) patients has not been well established as in Westerncountries. DA-9701, a novel prokinetic agent, stimulates gastric emptying and modulates visceral hypersensitivity in vivo and in human studies. This study was conducted to compare the efficacy of DA-9701 with a conventional PPI in mono or combination therapy in patients with FD. In this double-blind, randomized, non-inferiority trial, 389 patients diagnosed with FD using Rome III criteria were allocated among3 groups: 30-mg DA-9701 t.i.d (means 3 times a day), 40-mg pantoprazole, and 30-mg DA-9701 t.i.d + 40-mg pantoprazole. Theprimary efficacy end-point was a global assessment of the patient binary response or response on a 5-Likert scale after 4 weeks. The global symptomatic improvement was 60.5% in the DA-9701 group, 65.6% in the pantoprazole group, and 63.5% in the DA-9701 + pantoprazole group using a 5-Likert scale at week 4 with no significant difference among 3 groups (P = 0.685). Symptomimprovement measured by binary outcome was significantly achieved in each of the 3 groups, but not different among groups.Patients in all treatment groups reported significant improvement in the response rate and symptoms according to FD subtypes anddyspepsia-related quality of life (P DA-9701 improves global and individual symptoms and increases dyspepsia-specific quality of life in patients with FD. The efficacyof DA-9701 monotherapy is comparable with pantoprazole and there is no additive effect with combination of DA-9701 andpantoprazole in patients with FD.

Full Text Available Gloria Guidetti,1 Sara Viotti,1 Andreina Bruno,2 Daniela Converso1 1Department of Psychology, University of Turin, Turin, Italy; 2Department of Education Science, University of Genoa, Genoa, Italy Introduction: Work ability constitutes one of the most studied well-being indicators related to work. Past research highlighted the relationship with work-related resources and demands, and personal resources. However, no studies highlight the role of collective and self-efficacy beliefs in sustaining work ability. Purpose: The purpose of this study was to examine whether and by which mechanism work ability is linked with individual and collective efficacies in a sample of primary and middle school teachers. Materials and methods: Using a dataset consisting of 415 primary and middle school Italian teachers, the analysis tested for the mediating role of self-efficacy between collective efficacy and work ability. Results: Mediational analysis highlights that teachers’ self-efficacy totally mediates the relationship between collective efficacy and perceived work ability. Conclusion: Results of this study enhance the theoretical knowledge and empirical evidence regarding the link between teachers’ collective efficacy and self-efficacy, giving further emphasis to the concept of collective efficacy in school contexts. Moreover, the results contribute to the study of well-being in the teaching profession, highlighting a process that sustains and promotes levels of work ability through both collective and personal resources.

The acaricidal efficacy of nine marketed products, i.e. Acardust, Acarosan (foam and powder), Actelic 50, Artilin 3A (spirit and water base), liquid nitrogen, Paragerm AK, and Tymasil, and of intensive vacuum-cleaning have been compared on four different test surfaces: mattress, tufted carpet, gypsum board and rough wooden board, all covered with artificial house dust. They were inoculated with the house dust mite, Dermatophagoides pteronyssinus or the house-dust fungus Aspergillus repens for evaluation of the fungistatic claims of some products. The acaricidal activity of Tymasil did not surpass that of vacuuming; its fungistatic effect was not apparent. The other products showed complete to almost complete eradication on at least one of the substrates tested. Taking into account the results of acaricidal efficacy as well as the data on safety and practicality acquired earlier, Acarosan powder was considered first choice for carpet treatment. Acarosan and liquid nitrogen, were found to be effective in the treatment of mattress, pillow, upholstered furniture and heavy curtains. On wooden surfaces Acarosan was found to be both effective and safe, while Acardust, Actelic 50, Artilin 3A (both fungistatic as well as acaricidal), liquid nitrogen and Paragerm also passed the efficiency test.

　Methylxanthine is widely administered for the treatment of apnea of prematurity in many countries, and previous reports have clearly established that caffeine is effective for the treatment of apnea of prematurity. In Japan, caffeine has been available since December 2014. Thus, we compared the efficacy and safety of caffeine with that of aminophylline in our hospital. There was no significant difference between the caffeine group and aminophylline group regarding the characteristics of the study patients. The mean efficacy rate from day 1 to day 10 was 89.5% in the caffeine group, and 81.9% in the aminophylline group, although the rate of improvement in apnea episodes each day from day 1 to day 10 was not significantly different between the two groups. On the other hand, the adverse event rates in the caffeine group and the aminophylline group were 70.6% and 75.0%, respectively. No significant difference was observed in the adverse event rates between the two groups. Moreover, suspected abdominal distension due to the drug administration was more frequently observed with the aminophylline group. Our findings indicate that caffeine is as effective as aminophylline, while it is superior to aminophylline regarding its overall safety.

The objective of this study was to evaluate the antimicrobial efficacy of herbal alternatives (Emblica officinalis, Psidium guajava), BioPure MTAD, and 2.5% sodium hypochlorite against Enterococcus faecalis. The testing of the antimicrobial efficacy of selected medicaments against E. faecalis was done by the agar disk-diffusion method. Whatman paper discs of 6 mm diameter were prepared and soaked with the test solution. These discs were then placed onto the previously seeded agar Petri plates. Later, these plates were incubated for 48 h at 37 °C under the appropriate gaseous conditions in a CO2 incubator. A zone of inhibition was recorded in millimeter for each plate and the results were analyzed statistically. MTAD was found to be superior in its antibacterial abilities against E. faecalis compared with the other irrigants used. All the other tested irrigants showed significant zone of inhibition. BioPure MTAD offers better antibacterial efficacy than NaOCl. E. officinalis and P. guajava are effective antibacterial agents against E. faecalis and can be used to reduce root canal microflora and root canal failures.

Full Text Available BACKGROUND Psychotic disorders are a group of chronic debilitating psychiatric illness characterised by loss in touch with reality and disorders of thought, behaviour, appearance and speech. The second generation atypical antipsychotic olanzapine has been reported to be the commonly prescribed antipsychotic. However, olanzapine can cause adverse effects like weight gain, hyperglycaemia, diabetes, dyslipidaemia and metabolic syndrome. Quetiapine, another second generation antipsychotic has good efficacy and has become well established in the treatment of schizophrenia and manic episodes. There are reports on adverse effects of hyperglycaemia and diabetes with quetiapine, but these are comparatively lesser than olanzapine. The aim of the study is to compare the efficacy of olanzapine and quetiapine in patients with psychotic disorders. MATERIALS AND METHODS It was an unicentric, open label, prospective and comparative clinical study. Subjects (n=80 who were diagnosed with psychotic disorder were randomly assigned to receive olanzapine (group 1 or quetiapine (group 2. The efficacy of the two drugs was assessed on the basis Brief Psychiatric Rating Scale (BPRS scores at baseline, 1 week and 6 weeks. UKU scale (Udvalg Kliniske Undersogelser and laboratory investigations were used to assess the safety profile. RESULTS The two study groups had comparable sociodemographic profile.

Radiofrequency(RF surgery and trichloroacetic acid (TCA applications have been listed among the procedures for XP, but comparative studies are not available. Aim: To compare the efficacy of radiofrequency surgery versus trichloroacetic acid application in the treatment of XP. Settings and Design: 20 consecutive cases of XP attending dermatology, medicine and endocrinology out-patient departments of M.S.Ramaiah teaching hospital were enrolled for the study. It was an open-label clinical trial conducted in our hospital for a duration of 1 year. Materials and Methods: 20 consecutive patients conforming to inclusion criteria were selected for the study. For each patient, lesions were treated with radiofrequency ablation on one side and TCA application on the other side. Results: RF ablation was done for 12 patients over right eye lesions and 8 patients over the left eye lesions. TCA applications were done for 8 patients over right eye lesions and 12 patients over left eye lesions. 70% of lesions treated with RF ablation had a score of improvement of 4 and 70% of lesions treated with TCA application had a score of improvement of 4, at 4 weeks of follow-up. At four weeks of follow-up 40% in RF group and 15% in TCA group had scarring and 45% in RF group and 30% in TCA group had pigmentation. Conclusion: RF ablation as compared to TCA application, required fewer sessions for achieving more than 75% clearance of lesions. However, TCA applications were associated with fewer complications comparatively.

Using a sample of 45 women, this study compared the effectiveness of a previously studied (Mintz, Balzer, Zhao, & Bush, 2012) bibliotherapy intervention (Mintz, 2009), a similar self-help book (Hall, 2004), and a wait-list control (WLC) group. To examine intervention effectiveness, between and within group standardized effect sizes (interpreted with Cohen's, 1988 benchmarks .20 = small, .50 = medium, .80+ = large) and their confidence limits are used. In comparison to the WLC group, both interventions yielded large between-group posttest effect sizes on a measure of sexual desire. Additionally, large between-group posttest effect sizes were found for sexual satisfaction and lubrication among those reading the Mintz book. When examining within-group pretest to posttest effect sizes, medium to large effects were found for desire, lubrication, and orgasm for both books and for satisfaction and arousal for those reading the Mintz book. When directly comparing the books, all between-group posttest effect sizes were likely obtained by chance. It is concluded that both books are equally effective in terms of the outcome of desire, but whether or not there is differential efficacy in terms of other domains of sexual functioning is equivocal. Tentative evidence is provided for the longer term effectiveness of both books in enhancing desire. Arguing for applying criteria for empirically supported treatments to self-help, results are purported to establish the Mintz book as probably efficacious and to comprise a first step in this designation for the Hall book.

The psychological traits of cosmetic surgery patients (CSP) are important for selecting patients and postoperative patient satisfaction. A patient's self-esteem, self-efficacy, and self-assessment affect his or her motivation for cosmetic surgery, but the association among these traits remains unclear, especially in the Asian population. To clarify the association of a patient's psychological traits, decision to undergo cosmetic surgery, and the effectiveness of facial cosmetic surgery on the psychological conditions of young, female Chinese patients. Three different groups of young women (aged 18-30 years) from the Plastic Surgery Hospital, Chinese Academy of Medical Sciences, and 7 universities were enrolled from January 1, 2012, through December 31, 2014: CSPs (n = 161), general population controls (GPCs) (n = 355), and facial appearance raters (FARs) (n = 268). The last date of follow-up was January 20, 2015. Patient data from questionnaires were obtained preoperatively and 6 months postoperatively, and the data from the control groups were obtained immediately after enrollment. Front-view facial images of the study participants were taken and then shown to independent raters to assess the participants' facial appearances on a rating scale. Evaluation of self-esteem and self-efficacy, subjective and objective assessment of facial appearance, and structural equation models. A total of 163 CSPs and 387 GPCs were recruited for the study, and complete and valid data were obtained from 161 CSPs and 355 GPCs. All responses from the 268 FARs met the criteria for subsequent analysis. Of the questionnaires issued to the CSPs 6 months postoperatively, 126 valid responses were returned (response rate, 78.3%). Self-esteem and self-efficacy decreased significantly in preoperative patients compared with controls (P self-esteem and 21.50 [2.40] for CSPs and 28.59 [4.23] for GPCs for self-efficacy) and were found to be at nearly normal levels 6 months postoperatively (mean [SD

Rivaroxaban is a United States Food and Drug Administration-approved oral anticoagulant for venous thromboembolic disease; however, there is no information regarding the safety and its efficacy to support its use in patients after open or endovascular arterial interventions. We report the safety and efficacy of rivaroxaban vs warfarin in patients undergoing peripheral arterial interventions. This single-institution retrospective study analyzed all sequential patients from December 2012 to August 2014 (21 months) who were prescribed rivaroxaban or warfarin after a peripheral arterial procedure. Our study population was then compared using American College of Chest Physicians guidelines with patients then stratified as low, medium, or high risk for bleeding complications. Statistical analyses were performed using the Student t-test and χ 2 test to compare demographics, readmissions because of bleeding, and the need for secondary interventions. Logistic regression models were used for analysis of variables associated with bleeding complications and secondary interventions. The Fisher exact test was used for power analysis. There were 44 patients in the rivaroxaban group and 50 patients in the warfarin group. Differences between demographics and risk factors for bleeding between groups or reintervention rate were not statistically significant (P = .297). However, subgroup evaluation of the safety profile suggests that patients who were aged ≤65 years and on warfarin had an overall higher incidence of major bleeding (P = .020). Patients who were aged >65 years, undergoing open operation, had a significant risk for reintervention (P = .047) when they received rivaroxaban. Real-world experience using rivaroxaban and warfarin in patients after peripheral arterial procedures suggests a comparable safety and efficacy profile. Subgroup analysis of those requiring an open operation demonstrated a decreased bleeding risk when rivaroxaban was used (in those aged <65�

In this study, polyaminopropyl biguanide (PAPB) was compared to the molecularly closely related polyhexamethylene biguanide (PHMB) with respect to chemical relationship, antiseptic efficacy and cytotoxicity in vitro. Cytotoxicity for human keratinocytes (HaCaTs) and murine fibroblasts (L929) was determined according to ISO EN 10993-5 for both substances. Antimicrobial efficacy tests were performed via determination of the MBC, quantitative suspension method for substances and investigation of two PAPB- or PHMB-containing dressings against Staphyloccoccus aureus, Escherichia coli and Pseudomonas aeruginosa, according to international standards. Prior mass spectrometry was performed for chemical differentiation of the investigated substances. PHMB showed high toxicity even in low concentrations for both tested cell lines and a high antimicrobial efficacy against S. aureus and E. coli. In the case of PAPB, no or only low cytotoxicity was detected after 72 h, whilst comparable antibacterial features are lacking, as PAPB showed no relevant antimicrobial effects. Even though chemically closely related, PAPB proved to be ineffective in bacterial eradication, whilst PHMB showed a high efficacy. The discovery and establishment of safe and effective alternative antiseptics are important issues for the treatment of infected wounds. In particular, rising bacterial resistances to established agents, as well as ongoing discussions of potential toxic or carcinogenic effects emphasize this necessity. Nevertheless, the presented results highlight that even small changes in the chemical structure of related agents such as PHMB and PAPB can dramatically affect their efficacy and, therefore, need to be carefully distinguished and assessed side by side.

Self-efficacy has been associated with smoking cessation outcomes in many correlational research studies, but strong causal inferences are lacking. This study tested whether self-efficacy affects initial smoking cessation in a laboratory experiment, which will allow for stronger causal inferences in this domain of inquiry. Participants (n=103 motivated adult smokers) were provided with brief cessation treatment over three days in preparation for quitting on a target quit day (TQD). In addition, participants were randomized to one of two standard self-efficacy manipulations in the form of bogus feedback about their chances of quitting smoking. Participants in the Average Chances of Quitting (ACQ) condition took a computerized test and were told (falsely) that the test showed that they had the same chances of quitting as everyone else in the study. Participants in the High Chances of Quitting (HCQ) condition took the same computerized test and were told (falsely) that the test showed that they had a greater chance of quitting compared to everyone else in the study. The main outcome was whether participants were able to quit for 24h on the TQD. Results revealed that HCQ participants had a significantly greater chance of quitting smoking compared to ACQ participants. However, these effects were not attributable to changes in self-efficacy brought about by the manipulation. An exploration of other potential mediators showed that the manipulation actually influenced smoking outcome expectancies, and changes in these outcome expectancies influenced initial smoking cessation. The results highlight the conceptual and empirical challenges with manipulating self-efficacy in the smoking literature. Copyright © 2017. Published by Elsevier Ltd.

2015-03-14

A multi-site, masked, randomised parallel group study employing a double dummy treatment design was performed in canine veterinary patients to determine the comparative efficacy and safety of mavacoxib and carprofen in the treatment of pain and inflammation associated with osteoarthritis for a period of 134 days. Treatments were administered according to their respective summaries of product characteristics. Of 139 dogs screened, 124 were suitable for study participation: 62 of which were dosed with mavacoxib and 62 with carprofen. Both treatments resulted in a very similar pattern of considerable improvement as indicated in all parameters assessed by both owner and veterinarian. The primary efficacy endpoint 'overall improvement' was a composite score of owner assessments after approximately six weeks of treatment. Both drugs were remarkably effective, with 57/61 (93.4 per cent) of mavacoxib-treated dogs and 49/55 (89.1 per cent) of carprofen-treated dogs demonstrating overall improvement and with mavacoxib's efficacy being non-inferior to carprofen. The treatments had a similar safety profile as evidenced by documented adverse events and summaries of clinical pathology parameters. The positive clinical response to treatment along with the safety and dosing regimen of mavacoxib makes it an attractive therapy for canine osteoarthritis. British Veterinary Association.

Full Text Available BACKGROUND: Previous meta-analyses comparing the efficacy of psychotherapeutic interventions for depression were clouded by a limited number of within-study treatment comparisons. This study used network meta-analysis, a novel methodological approach that integrates direct and indirect evidence from randomised controlled studies, to re-examine the comparative efficacy of seven psychotherapeutic interventions for adult depression. METHODS AND FINDINGS: We conducted systematic literature searches in PubMed, PsycINFO, and Embase up to November 2012, and identified additional studies through earlier meta-analyses and the references of included studies. We identified 198 studies, including 15,118 adult patients with depression, and coded moderator variables. Each of the seven psychotherapeutic interventions was superior to a waitlist control condition with moderate to large effects (range d = -0.62 to d = -0.92. Relative effects of different psychotherapeutic interventions on depressive symptoms were absent to small (range d = 0.01 to d = -0.30. Interpersonal therapy was significantly more effective than supportive therapy (d = -0.30, 95% credibility interval [CrI] [-0.54 to -0.05]. Moderator analysis showed that patient characteristics had no influence on treatment effects, but identified aspects of study quality and sample size as effect modifiers. Smaller effects were found in studies of at least moderate (Δd = 0.29 [-0.01 to 0.58]; p = 0.063 and large size (Δd = 0.33 [0.08 to 0.61]; p = 0.012 and those that had adequate outcome assessment (Δd = 0.38 [-0.06 to 0.87]; p = 0.100. Stepwise restriction of analyses by sample size showed robust effects for cognitive-behavioural therapy, interpersonal therapy, and problem-solving therapy (all d>0.46 compared to waitlist. Empirical evidence from large studies was unavailable or limited for other psychotherapeutic interventions. CONCLUSIONS: Overall our

Full Text Available BACKGROUND: Preterm labour is onset of labour between 20 weeks and 37 completed weeks of gestation. Tocolytics are pharmacological agents that relax the uterine myometrium and inhibit uterine contractions leading to abolition of preterm labour. Many tocolytic drugs have been developed and used and several experimental drugs are being evaluated. Future research is needed for development of drugs with more utero - selectivity and fewer side effects. Ritodrine hydrochloride is now considered one of the most effective tocolytic drug . However, the use of nitroglycerine patch has shown comparable results and there is a need for further critical evaluation by well - planned and well monitored studies. AIM: To compare the efficacy of transdermal glyceryl trinitrate and intravenous ritodrin e as tocolytics. MATERIAL AND METHODS: The study was conducted on patients who attended Bapuji Hospital , Chigateri Hospital and women and child hospital, attached to J .J.M . Medical College, Davangere. One hundred patients who were admitted and clinically di agnosed with preterm labour were randomised either to group 1, treated with glyceryl trinitrate patch or group II, treated with ritodrine, with fifty patients in each group. ANALYSIS: Descriptive data that included mean, Standard deviation, percentages wer e determined and presented for each group. Difference between two groups was compared by Mann - Whitney test for continuous data and chi - square test for categorical data. P Valve of 0.05 or less was considered for statistical significance. RESULTS: mean per centage prolongation of gestation with glyceryl trinitrate was 58±45.9 and with Ritodrine , it was 62±44.6. Mean absolute prolongation of gestation with glyceryl trinitrate was 3.22 weeks and with Ritodrine it was 3.18 weeks. CONCLUSION: Both glyceryl trini trate and ritodrine were comparable in prolongation of gestation in patients in preterm labour, both in duration and in terms of success. The

Background The superiority of an intervention combining two sets of theory-based behavior change techniques targeting planning and self-efficacy over an intervention targeting planning only or self-efficacy only has rarely been investigated. Purpose We compared the influence of self-efficacy, planning, and self-efficacy+planning interventions with an education-based control condition on adolescents’ body fat, assuming mediating effects of respective social cognitive variables and moderate-to-vigorous physical activity (MVPA). The moderating role of the built environment was examined. Methods Participants (N = 1217, aged 14–18 years) were randomly assigned to four conditions: planning (n = 270), self-efficacy (n = 311), self-efficacy+planning (n = 351), and control (n = 285). The measurement was conducted at baseline (T1), two-month follow-up (T2), and fourteen-month follow-up (T3). Interventions/control group procedures were delivered at T1 and T2. Percent of body fat tissue (measured at T1 and T3) was the main outcome. Social cognitive mediators (self-efficacy and planning) were assessed at T1 and T2. The behavioral mediator (MVPA) and the presence of built MVPA facilities (the moderator) were evaluated at T1 and T3. Results Similar small increases of body fat were found across the three intervention groups, but the increment of body fat was significantly larger in the control group. On average, differences between control and intervention groups translated to approximately 1% of body fat. Effects of the interventions on body fat were mediated by relevant social cognitive variables and MVPA. A lower increase of body fat was found among intervention group participants who had access to newly-built MVPA facilities. Conclusions We found no superiority of an intervention targeting two social cognitive variables over the intervention targeting one cognition only. PMID:27410961

Benzodiazepines cause a high proportion of adverse effects while non-benzodiazepine compounds have demonstrated high efficacy and less adverse effects in patients with insomnia. The objective of this study was to compare the effectiveness and safety of non-BZ zaleplon and zolpidem in primary insomnia. This was a randomized, double-blind, active-controlled, double-dummy, comparative study. A total of 48 patients were enrolled, of which 45 patients completed the study. Patients who entered the study were required to take the study drug orally once daily at bedtime for two weeks. Each patient kept a sleep diary and answered a questionnaire. We used these documents to measure and evaluate changes from baseline to Week 2 in sleep latency, duration and quality of sleep, the number of awakenings and incidence of rebound insomnia. The data revealed a significant decrease in sleep latency from baseline to Week 2 for patients receiving zaleplon 10 mg and zolpidem 10 mg. Patients receiving zaleplon exhibited a marginally greater, but not statistically significant, reduction in sleep latency than those who received zolpidem. There was no significant difference in the frequency of adverse effects between the zaleplon and zolpidem groups; however, during this clinical trial there was one lethal event caused by a traffic accident in the zaleplon group. There was no significant difference between zaleplon and zolpidem in the efficacy of reducing sleep latency or adverse effects. A large pharmacovigilance study is needed before concluding that either zolpidem or zaleplon is free from next-day residual effects.

Full Text Available This study aims to compare efficacy of self-learning, audiovisual, and fun activity instructional approaches among school students of Patna, the capital city of Bihar state of India, to develop environmental awareness. The study participants include 144 randomly selected students (72 girls and 72 boys from eight different schools of Patna. During a weeklong environmental awareness program, students were instructed using above three approaches of instruction. Data have been analyzed by using linear regression. Regression was carried out to eliminate the effect of general mental ability (GMA scores. The results suggest about overall superiority of fun activity approach over other approaches tested in the present study. However, awareness gain has been significant among the students with high GMA when instructed through audiovisual approach.

A gender study investigating physics self-efficacy

Sawtelle, Vashti

The underrepresentation of women in physics has been well documented and a source of concern for both policy makers and educators. My dissertation focuses on understanding the role self-efficacy plays in retaining students, particularly women, in introductory physics. I use an explanatory mixed methods approach to first investigate quantitatively the influence of self-efficacy in predicting success and then to qualitatively explore the development of self-efficacy. In the initial quantitative studies, I explore the utility of self-efficacy in predicting the success of introductory physics students, both women and men. Results indicate that self-efficacy is a significant predictor of success for all students. I then disaggregate the data to examine how self-efficacy develops differently for women and men in the introductory physics course. Results show women rely on different sources of self-efficacy than do men, and that a particular instructional environment, Modeling Instruction, has a positive impact on these sources of self-efficacy. In the qualitative phase of the project, this dissertation focuses on the development of self-efficacy. Using the qualitative tool of microanalysis, I introduce a methodology for understanding how self-efficacy develops moment-by-moment using the lens of self-efficacy opportunities. I then use the characterizations of self-efficacy opportunities to focus on a particular course environment and to identify and describe a mechanism by which Modeling Instruction impacts student self-efficacy. Results indicate that the emphasizing the development and deployment of models affords opportunities to impact self-efficacy. The findings of this dissertation indicate that introducing key elements into the classroom, such as cooperative group work, model development and deployment, and interaction with the instructor, create a mechanism by which instructors can impact the self-efficacy of their students. Results from this study indicate that

Due to increased resistance and safety concerns with insecticide-based pediculicides, there is growing demand for head lice treatments with a physical mode of action. Certain mineral oils kill lice by blocking spiracles or by disrupting the epicuticular wax layer. The present study was performed to evaluate efficacy and safety of a mineral oil-based shampoo. This randomized, controlled, investigator-blinded, monocentric study (EudraCT registration no. 2014-002918-23) was performed from October 2014-June 2015 in Germany. A mineral oil shampoo (Mosquito® Med Läuse Shampoo 10 in Germany, Paranix or Silcap shampoo elsewhere), registered as medical device, was compared to a conventional, locally reimbursed, pyrethroid-based pediculicide (Goldgeist® Forte solution). In total, 107 patients (>1 year) with confirmed head lice infestation were included (test arm: n = 53; control arm: n = 54). All subjects received two applications of either test or control product at day 0 and day 7, according to the instructions for use. Efficacy and safety was evaluated directly, 1h and 24h after first application, before and after second treatment, and at day 10. The main objective was demonstrating a cure rate for the test product, being superior to 70% at day 10. Cure rates at day 10 (corrected for re-infestation) for the test product (96.1%) and control (94%) significantly exceeded the pre-defined target (70%) (p shampoo) can be safe and effective alternatives for insecticide-based pediculicides, with less risk for development of resistance because of the physical mode of action.

Full Text Available Background: Chronic and delayed healing wounds are the significant health problems globally. Microbial bio burden in the form of biofilms contribute significantly for chronicity and delayed healing. Management of biofilm is complex task. Effective management of biofilms significantly reduces healing time. Raw unprocessed honey has several antibacterial properties and factors stimulating wound healing. Aim and Objectives: Acomparative study was taken to compare the efficacy of local application of raw unprocessed honey versus mechanical debridement and antiseptic application in terms of biofilm eradication and enhanced wound healing. Method and Materials: Ninety patients with non healing wounds having biofilms were included and divided equally (forty five each for local application of honey and mechanical debridement respectively. They were managed similarly and assessed for presence or eradication of biofilms, healing process and final outcome regularly. Results: Data analysed showed presence of biofilms in chronic wounds was 60% and 68% in study and control groups respectively. Time for appearance of healthy granulation tissue was significantly less (P=0.022 Mean duration for eradication of biofilms was less with (P=0.025 Mean hospital stay was also reduced (P=0.004. Conclusion: Raw unprocessed honey is a good, simple and effective solution for eradication of biofilms and enhances healing in non healing ulcers.

2012-12-01

There is a lack of research investigating parental self-efficacy in parents of infants born preterm as well as a paucity of parental self-efficacy measures that are domain-specific and theoretically grounded. This study aimed to compare parental self-efficacy in parents of infants born term, preterm and very preterm as well as to test whether parental self-efficacy mediates the relationship between psychological symptoms and parental competence. In order to achieve this, a new measure of parental self-efficacy and parental competence relevant for the preterm population and consistent with Bandura's (1977, 1986, 1989) conceptualisation of self-efficacy was developed. Participants included 155 parents, 83 of whom were parents of very preterm (GAparents of preterm (GAparents of term born infants. Parents completed the Preterm Parenting & Self-Efficacy Checklist (the new measure), Family Demographic Questionnaire, Depression Anxiety Stress Scale and Self-Efficacy Questionnaire. This initial study indicates that the Preterm Parenting & Self-Efficacy Checklist has adequate content validity, construct validity, internal consistency and split half reliability. Contrary to expectations, parents of very preterm infants did not report significantly lower overall levels of parental self-efficacy or significantly higher levels of psychological symptoms compared to parents of preterm and term infants. Parental self-efficacy about parenting tasks mediated the relationship between psychological symptoms and self perceived parental competence as predicted. Clinical implications of the results and suggestions for future research are discussed. Crown Copyright © 2012. Published by Elsevier Inc. All rights reserved.

There is limited amount of data available on the comparative efficacy of ibrutinib and idelalisib, the B-cell receptor inhibitors (BCRi) newly approved for relapsed/refractory chronic lymphocytic leukemia/small lymphocytic lymphoma (r/r CLL/SLL) treatment. The aim of our study was to analyze and compare the outcomes of real-world r/r CLL/SLL patients treated with these two BCRi in outside clinical trials. A comparative case matched 1:2 analysis was performed on idelalisib combined with rituximab and ibrutinib efficacy in 102 patients with r/r CLL/SLL from two observational studies of the Polish Adult Leukemia Group (PALG). Both therapies produced similar overall response rates (idelalisib plus rituximab 76.4% and ibrutinib 72.1%). Median progression-free survival (PFS) and overall survival (OS) in both groups were not reached. Furthermore, no significant difference was observed between both BCRi regimens in regard to PFS (HR=0.75, 95% CI=0.30-1.86, p=0.55) and OS (HR=0.65, 95%CI=0.26-1.68, p=0.39). In summary, the results of this retrospective analysis suggest that idelalisib combined with rituximab and ibrutinib therapies have comparable activity in r/r CLL/SLL in daily clinical practice.

Effective education of practical skills can alter clinician behaviour, positively influence patient outcomes, and reduce the risk of patient harm. This study compares the efficacy of two innovative practical skill teaching methods, against a traditional teaching method. Year three pre-clinical physiotherapy students consented to participate in a randomised controlled trial, with concealed allocation and blinded participants and outcome assessment. Each of the three randomly allocated groups were exposed to a different practical skills teaching method (traditional, pre-recorded video tutorial or student self-video) for two specific practical skills during the semester. Clinical performance was assessed using an objective structured clinical examination (OSCE). The students were also administered a questionnaire to gain the participants level of satisfaction with the teaching method, and their perceptions of the teaching methods educational value. There were no significant differences in clinical performance between the three practical skill teaching methods as measured in the OSCE, or for student ratings of satisfaction. A significant difference existed between the methods for the student ratings of perceived educational value, with the teaching approaches of pre-recorded video tutorial and student self-video being rated higher than 'traditional' live tutoring. Alternative teaching methods to traditional live tutoring can produce equivalent learning outcomes when applied to the practical skill development of undergraduate health professional students. The use of alternative practical skill teaching methods may allow for greater flexibility for both staff and infrastructure resource allocation.

Full Text Available Background: Toenail onychomycosis is a challenge for clinicians to treat. While both Itraconazole and terbinafine have proven to be effective against onychomycosis, very little is known about their comparative efficacy in achieving mycological and clinical cure. Aim: The purpose of this meta-analysis is to compare the efficacy of continuous terbinafine with intermittent itraconazole in the treatment of toenail onychomycosis. Material and Methods: all RCTs comparing continuous terbinafine with intermittent itraconazole were identified from PUBMED and BIDS electronic database. Results: analysis of total eight trials including 1181 patients state that treatment with continuous terbinafine is more likely to produce mycological and clinical cure compared to intermittent itraconazole with odds ratio 2.3(95% CI, 1.7 to 3.0 P< 0.0001 Conclusion: though both itraconazole and terbinafine are well tolerated and highly effective drugs, continuous terbinafine is more effective than intermittent itraconazole at achieving mycological cure of toenail onychomycosis

Nursing home (NH). 75 NH residents with AD and agitation, randomized to citalopram (n = 25), quetiapine (n = 25), or olanzapine (n = 25). Changes in Neuropsychiatric Inventory (NPI) agitation subscale score and the modified Alzheimer Disease Cooperative Study-Clinical Global Impression of Change (mADCS-CGIC) were used to assess treatment efficacy. Participants were surveilled for adverse health outcomes. Citalopram treatment (30±5.8 mg/d) resulted in similar 6-month efficacy compared to both quetiapine (94.0±40.4 mg/d) and olanzapine (5.2±1.6 mg/d), lower occurrence of falls than olanzapine [odds ratio (OR) = 0.81, 95% confidence interval (CI) = 0.68-0.97, P = .012], lower incidence of orthostatic hypotension than both quetiapine (OR = 0.80, 95% CI = 0.66-0.95, P = .032) and olanzapine (OR = 0.75, 95% CI = 0.69-0.91, P = .02), and less all-cause hospitalizations than both quetiapine (OR = 0.92, 95% CI = 0.88-0.95, P = .016) and olanzapine (OR = 0.78, 95% CI = 0.64-0.92, P = .004), after multiple adjustment for potentially confounding variables. No differences were observed for cognitive and functional decline, QTc prolongation, and infections. Citalopram resulted in similar efficacy and less adverse outcomes when compared to 2 atypical antipsychotics for treatment of agitation in NH residents with AD. Replication of these findings and assessment of long-term efficacy and safety of citalopram for treatment of neuropsychiatric symptoms in dementia are needed.

Julien Zwang

Full Text Available Extensive use of praziquantel for treatment and control of schistosomiasis requires a comprehensive understanding of efficacy and safety of various doses for different Schistosoma species.A systematic review and meta-analysis of comparative and non-comparative trials of praziquantel at any dose for any Schistosoma species assessed within two months post-treatment. Of 273 studies identified, 55 were eligible (19,499 subjects treated with praziquantel, control treatment or placebo. Most studied were in school-aged children (64%, S. mansoni (58%, and the 40 mg/kg dose (56%; 68% of subjects were in Africa. Efficacy was assessed as cure rate (CR, n=17,017 and egg reduction rate (ERR, n=13,007; safety as adverse events (AE incidence. The WHO-recommended dose of praziquantel 40 mg/kg achieved CRs of 94.7% (95%CI 92.2-98.0 for S. japonicum, 77.1% (68.4-85.1 for S. haematobium, 76.7% (95%CI 71.9-81.2 for S. mansoni, and 63.5% (95%CI 48.2-77.0 for mixed S. haematobium/S. mansoni infections. Using a random-effect meta-analysis regression model, a dose-effect for CR was found up to 40 mg/kg for S. mansoni and 30 mg/kg for S. haematobium. The mean ERR was 95% for S. japonicum, 94.1% for S. haematobium, and 86.3% for S. mansoni. No significant relationship between dose and ERR was detected. Tolerability was assessed in 40 studies (12,435 subjects. On average, 56.9% (95%CI 47.4-67.9 of the subjects receiving praziquantel 40 mg/kg experienced an AE. The incidence of AEs ranged from 2.3% for urticaria to 31.1% for abdominal pain.The large number of subjects allows generalizable conclusions despite the inherent limitations of aggregated-data meta-analyses. The choice of praziquantel dose of 40 mg/kg is justified as a reasonable compromise for all species and ages, although in a proportion of sites efficacy may be lower than expected and age effects could not be fully explored.

Efficacy and Safety of a Mineral Oil-Based Head Lice Shampoo: A Randomized, Controlled, Investigator-Blinded, Comparative Study.

Directory of Open Access Journals (Sweden)

Luise Wolf

Full Text Available Due to increased resistance and safety concerns with insecticide-based pediculicides, there is growing demand for head lice treatments with a physical mode of action. Certain mineral oils kill lice by blocking spiracles or by disrupting the epicuticular wax layer. The present study was performed to evaluate efficacy and safety of a mineral oil-based shampoo.This randomized, controlled, investigator-blinded, monocentric study (EudraCT registration no. 2014-002918-23 was performed from October 2014-June 2015 in Germany. A mineral oil shampoo (Mosquito® Med Läuse Shampoo 10 in Germany, Paranix or Silcap shampoo elsewhere, registered as medical device, was compared to a conventional, locally reimbursed, pyrethroid-based pediculicide (Goldgeist® Forte solution. In total, 107 patients (>1 year with confirmed head lice infestation were included (test arm: n = 53; control arm: n = 54. All subjects received two applications of either test or control product at day 0 and day 7, according to the instructions for use. Efficacy and safety was evaluated directly, 1h and 24h after first application, before and after second treatment, and at day 10. The main objective was demonstrating a cure rate for the test product, being superior to 70% at day 10.Cure rates at day 10 (corrected for re-infestation for the test product (96.1% and control (94% significantly exceeded the pre-defined target (70% (p < 0.001, 2-sided, 1-sample, chi-square test with confirmed non-inferiority for the test product. Over all visits, cure rates were consistently higher for the test product, whereas more initially-cured subjects remained lice-free until end of study (78%; control: 60%. Both products were safe and well tolerated, offering good esthetical effects.This study showed that substance-based medical devices (including the tested mineral oil shampoo can be safe and effective alternatives for insecticide-based pediculicides, with less risk for development of resistance because

Full Text Available Biological therapies are increasingly used to treat ulcerative colitis (UC.To compare the efficacy of biologics in adults with moderately-to-severely active UC, stratified by prior exposure to anti-tumour necrosis factor (anti-TNF therapy.A systematic literature review was undertaken to identify studies of biologics approved for UC. Network meta-analysis was conducted for endpoints at induction and maintenance.Seven studies were included in the meta-analysis of induction treatment for anti-TNF therapy-naïve patients. All biologics were more effective than placebo in inducing clinical response, clinical remission, and mucosal healing. Infliximab demonstrated a statistically significant improvement over adalimumab in clinical response (odds ratio [OR] [95% credible interval (CrI]: 2.19 [1.35-3.55], clinical remission (OR [95% CrI]: 2.81 [1.49-5.49], and mucosal healing (OR [95% CrI]: 2.23 [1.21-4.14]; there were no other significant differences between biologics for induction efficacy. Five studies were included in the meta-analysis of maintenance treatment, two studies rerandomised responder patients at end of induction, and three followed the same patients 'straight through'. To account for design differences, the number of responders at end of induction was assumed to be equivalent to the number rerandomised. Vedolizumab showed significantly different durable clinical response from comparators (OR [95% CrI] infliximab 3.18 [1.14-9.20], golimumab 2.33 [1.04-5.41], and adalimumab 3.96 [1.67-9.84]. In anti-TNF therapy-experienced patients, only vedolizumab and adalimumab could be compared. At induction, no significant differences in efficacy were seen. During maintenance, vedolizumab showed significantly improved rates of mucosal healing versus adalimumab (OR [95% CrI]: 6.72 [1.36-41.0].This study expands the understanding of comparative efficacies of biologic treatments for UC, encompassing outcomes and populations not previously studied.

Full Text Available Air abrasion as a caries removal technique is less aggressive than conventional techniques and is compatible for use with adhesive restorative materials. Alumina, while being currently the most common abrasive used for cutting, has controversial health and safety issues and no remineralisation properties. The alternative, a bioactive glass, 45S5, has the advantage of promoting hard tissue remineralisation. However, 45S5 is slow as a cutting abrasive and lacks fluoride in its formulation. The aim of this study was to compare the cutting efficacy of dentine using a customised fluoride-containing bioactive glass Na0SR (38–80 μm versus the conventional alumina abrasive (29 μm in an air abrasion set-up. Fluoride was incorporated into Na0SR to enhance its remineralisation properties while strontium was included to increase its radiopacity. Powder outflow rate was recorded prior to the cutting tests. Principal air abrasion cutting tests were carried out on pristine ivory dentine. The abrasion depths were quantified and compared using X-ray microtomography. Na0SR was found to create deeper cavities than alumina (p<0.05 despite its lower powder outflow rate and predictably reduced hardness. The sharper edges of the Na0SR glass particles might improve the cutting efficiency. In conclusion, Na0SR was more efficacious than alumina for air abrasion cutting of dentine.

Full Text Available Désirée Larenas-Linnemann Pediatric Allergy and Asthma Clinic, Department of Investigation, Hospital Médica Sur, México City, México Abstract: Due to differences between allergen immunotherapy (AIT trials in patient populations, trial design (including primary efficacy variables, the definition of a pollen season, data analysis, and comparisons between AIT products with existing data, is not possible nor valid. The efficacy of two grass pollen AIT tablets, Oralair® and Grazax®/Grastek®, should not be compared by looking at the percentage of score improvement in their respective trials. However, the evidence available concerning the efficacy and safety in trials can be compared by paying close attention to the scientific quality of the trials, details in the administration schedules, and safety issues. It can be concluded due to the high level of evidence available, that Oralair® is effective in a pre (2-months-coseasonal schedule to reduce symptoms and medication use, and improve a patients’ quality of life during the treatment season. For the long-term, where the quality of efficacy evidence is moderate at 2-year posttreatment due to a high dropout rate, the pre (4-months-coseasonal schedule should be used. No clinical efficacy data exists for starting treatment in-season, but the clinical onset of action of Oralair® is detectable after only 1 month of treatment. In the pivotal trials in Europe and the USA, no tablet-related epinephrine was needed, though some rare severe local reactions have been reported. Research for Grazax®/Grastek® showed that the long-term efficacy needs a continuous 3-year administration (moderate-low quality evidence available, and in two patients, tablet-related epinephrine was given. Further details on the comparative efficacy of both tablets would only be possible if both were evaluated in the same, adequately powered trial.

To compare the efficacy of thiazolidinediones (TZDs) and metformin in polycystic ovary syndrome (PCOS) patients. This systematic review study was conducted at Shengjing Hospital of China Medical University, Shenyang, China between January and February 2012. We searched the following databases MEDLINE, EMBASE, the Cochrane Library, and Chinese National Knowledge Infrastructure until January 2012. Six randomized controlled trials records involving 267 patients were retrieved. The effect of TZDs on body mass index (BMI) was significantly lower than metformin (p=0.001; standardized mean difference [SMD] = 0.40, 95% confidence interval [CI]; 0.16-0.65). The effect of TZDs on the Homeostasis Model of Assessment-Insulin Resistance Index was not significantly different from metformin (p=0.955, SMD = 0.01, 95% CI: -0.38-0.40). The effect of TZDs on the androgen level was not significantly different from metformin (serum total testosterone: p=0.287, SMD = 0.20, 95% CI: -0.17-0.57). Compared to metformin, TZDs had the same effectiveness in treating insulin sensitivity and lowering androgen in PCOS patients, but the effect on weight loss was not as good as metformin.

Full Text Available Background. The purpose of this study was to investigate the clinical efficacy and safety of Benjakul (BJK extract for treating primary osteoarthritis (OA of the knee compared with diclofenac. Methods. A phase 2, double blind, randomized, and controlled study was conducted. The BJK group received 300 mg of BJK extract per day, while another group received 75 mg of diclofenac per day. All patients were followed up at 14 and 28 days. The changing of visual analogue scale (VAS for pain, 100-meter walking times, the modified Thai WOMAC index scores, and the global assessment were evaluated for efficacy. For safety issue, clinical signs and symptoms, complete physical examination, and renal and liver function were evaluated. Results. 39 and 38 patients for BJK extract group and diclofenac group were evaluated. For efficacy, all patients from both groups reported a decrease in the VAS pain score and 100-meter walking times but only the diclofenac group showed significant reduction of both measurements when compared with day 0. The modified Thai WOMAC scores of both groups were significantly reduced from baseline. However, all efficacy outcomes were not significantly different for both groups. For safety outcomes, the patients from both groups had no severe adverse events reported and only BJK had no toxicity in renal and liver functions. Conclusions. The BJK remedy extract showed equal clinical efficacy in relieving symptoms of OA knee when compared with diclofenac.

Tinea pedis is one of the world's most prevalent dermatophyte infections. MedSpray™ tinea pedis 1 % w/w (topical spray) is a novel, easy-to-use propellant-based spray formulation containing 1 % w/w terbinafine, requiring no manipulation at the site of infection. This is in contrast to the only formulation currently approved in Europe for single application (none are approved in the USA for single use), which is Lamisil(®) Once 1 % w/w (topical solution), containing 1 % w/w terbinafine hydrochloride, which requires manipulation on the affected area. The aim of this study was to evaluate the efficacy, tolerability and consumer acceptability of a topical spray versus a topical solution in the treatment of tinea pedis. This study is a phase IIa, randomised, observer-blind, non-inferiority comparative study of the topical spray compared with the topical solution over a 12-week study period. The study was conducted at Bioskin GmbH, Hamburg and Berlin. Patients (n = 120) who presented with the presence of interdigital tinea pedis caused by dermatophytes on one or both feet were enrolled in the study. Patients were randomly assigned between the two treatment groups. Either the topical spray or the topical solution was administered by the study nurse and consisted of a single application (equivalent to 20 mg of terbinafine per foot) on day 1 of the study. No further applications were made for the duration of the study. The hypothesis formulated before commencement of the study was that the topical spray would prove to be non-inferior to the topical solution. Efficacy assessments, including clinical signs and symptoms, mycology and microscopy were performed at baseline and 1, 6 and 12 weeks after treatment. The rate of mycological cure at week 1 was statistically equivalent for both treatments. There was a significant reduction in the overall clinical score as assessed by the Physician's Global Assessment of signs and symptoms for both treatment groups. The topical

Background Statin treatment in association with physical exercise can substantially reduce mortality in dyslipidaemic individuals. However, the available data to compare the efficacy and safety of statins and exercise combination therapy with statin monotherapy are limited. Design Systematic review and meta-analysis. Methods We systematically searched PubMed, Embase and the Cochrane Library from database inception until December 2016. We included randomised and non-randomised studies that compared the efficacy and safety of statins and exercise combination therapy with statin monotherapy in patients with dyslipidaemia. Standardised mean differences were calculated and pooled by means of fixed effects models. The risk of bias and heterogeneity among trials was also assessed. Seven articles were assessed in terms of the efficacy of therapy and 13 from the viewpoint of therapeutic safety. Results In terms of efficacy, statins and exercise combination decreased the incidence of diabetes mellitus, improved insulin sensitivity and inflammation, but caused no change in lipid profile compared to statins alone. In terms of safety, statins and exercise combination increased peak oxygen uptake (standardised mean difference 1.01, 95% confidence interval 0.46 to 1.57) compared to statins alone. In contrast to statin-induced myopathy, chronic exercise training prior to statin treatment could counteract statin-induced adverse effects in skeletal muscle. Conclusion Statins and exercise combination therapy is more effective than statin monotherapy in terms of insulin sensitivity, inflammation and exercise capacity. The small number of studies warrants the need for more randomised controlled trials evaluating the efficacy and safety of combination therapy.

The effect of iron fortification is generally assumed to be less than iron supplementation; however, the magnitude of difference in effects is not known. The present study aims to compare the efficacy of these two strategies on anaemia and iron status. After screening on low Hb, 425 anaemic children in six primary schools in Tam Nong district of Phu Tho province were included in a randomized, placebo-controlled trial comparing two groups receiving iron fortified instant noodles or iron supplementation for 6 months and a control group, with children in all groups having been dewormed. Blood samples were collected before and after intervention for haemoglobin, serum ferritin (SF), serum transferrin receptor (TfR), C-reactive protein (CRP), and haemoglobinopathies analysis. Regression analysis was used to assess the effect of iron fortification and iron supplementation on haemoglobin concentration, SF, TfR, body iron, and anaemic status as outcome variables. The improvement of haemoglobin, SF, and body iron level in the group receiving iron fortification was 42% (2.6 g/L versus 6.2 g/L), 20% (23.5 microg/L versus 117.3 microg/L), and 31.3% (1.4 mg/kg versus 4.4 mg/kg) of that in the iron supplementation group. The prevalence of anaemia dropped to 15.1% in the control group, with an additional reduction of anaemia of 8.5% in the iron supplementation group. The additional reduction due to iron fortification was 5.4%, which amounts to well over 50% of the impact of supplementation. In conclusion, the efficacy of iron fortification based on reduction of prevalence of anaemia, and on the change in haemoglobin level, is about half of the maximum impact of supplementation in case of optimal compliance. Thus, in a population of anaemic children with mild iron deficiency, iron fortification should be the preferred strategy to combat anaemia.

Antifungal efficacy of photochemical cross-linking (PACK-CXL) with 0.1% and 0.25% riboflavin was evaluated with a comparative in vitro study. Candida albicans and Aspergillus fumigatus ATCC reference strains, Candida parapsilosis, Aspergillus fumigatus, Fusarium solani, Scedosporium apiospermum, and Alternaria alternata strains isolated from keratitis cases were chosen as targeted microorganisms. Unique "black plate method" was developed in polystyrene microplates. Riboflavin suspensions in 0.1% and 0.25% were separately added into inoculated wells. Non-inoculated wells were filled by black colored dye in order to protect treated wells from reflection of UV treatment. After ultraviolet A (UVA) treatment, each well was evaluated by microbiological culture in order to count viable fungal colonies. Fungal killing rate was calculated by comparing fungal counts (CFU/mL) before and after UVA application of riboflavin-added wells. Four different fungal inoculum concentrations of targeted microorganisms, including 10 4 , 10 3 , 10 2 , and 10 1 CFU/mL, were assayed. PACK-CXL with 0.25% riboflavin was found to be highly effective on fungal cells even in 10 4 CFU/mL of concentration. PACK-CXL appears as a promising treatment option for difficult-to-treat cases of fungal keratitis and 0.25% riboflavin concentration increases fungicidal effect of the procedure dramatically.

Four "third-generation" antiepileptic drugs (AEDs) were approved for adjunctive treatment of refractory focal onset seizures during the past 10 years. Long-term efficacy and safety of the drugs were demonstrated in large extension studies and in reports of subgroups of patients not studied in pivotal trials. Reviewing extension study and post-marketing outcome series for the four newer AEDs-lacosamide, perampanel, eslicarbazepine acetate and brivaracetam-can guide clinicians in treating and monitoring patients. AED extension studies evaluate treatment retention, drug tolerability, and drug safety during individualized treatment with flexible dosing and thus provide information not available in rigid pivotal trials. Patient retention in the studies ranged from 75 to 80% at 1 year and from 36 to 68% at 2-year treatment intervals. Safety findings were generally similar to those of pivotal trials, with no major safety risks identified and with several specific adverse drug effects, such as hyponatremia, reported. The third-generation AEDs, some through new mechanisms and others with improved tolerability compared to related AEDs, provide new options in efficacy and tolerability.

Woody vegetation cultivated for moisture management on evapotranspiration (ET) landfill covers could potentially serve a secondary function as a biomass crop. However, research is required to evaluate the extent to which trees could be harvested from ET covers without significantly impacting their moisture management function. This study investigated the drainage through a six-year-old, primarily poplar/cottonwood ET test cover for a period of one year following the harvest of all woody biomass exceeding a height of 30 cm above ground surface. Results were compared to previously reported drainage observed during the years leading up to the coppice event. In the first year following coppice, the ET cover was found to be 93% effective at redirecting moisture during the spring/summer season, and 95% effective during the subsequent fall/winter season. This was slightly lower than the 95% and 100% efficacy observed in the spring/summer and fall/winter seasons, respectively, during the final measured year prior to coppice. However, the post-coppice efficacy was higher than the efficacy observed during the first three years following establishment of the cover. While additional longer-term studies are recommended, this project demonstrated that woody ET covers could potentially produce harvestable biomass while still effectively managing aerial moisture.

Prostate-specific antigen (PSA)-based screening for prostate cancer (PC) has dramatically increased early diagnosis. Current imaging techniques are not optimal to stage early PC adequately. A promising alternative to PC imaging is peptide-based scintigraphy using radiolabelled bombesin (BN) analogues that bind to gastrin-releasing peptide receptors (GRPR) being overexpressed in PC. When labelled to appropriate radionuclides BN targeting of GRPRs may also provide applications for peptide radionuclide receptor therapy (PRRT). Assessment studies under identical experimental conditions allowing a reliable comparison of the potential of such analogues are lacking. This study was performed to evaluate and directly compare five promising radiolabelled BN analogues for their targeting efficacy for PC under standardised conditions. The BN agonists [{sup 111}In]DOTA-PESIN, [{sup 111}In]AMBA, [{sup 111}In]MP2346 and [{sup 111}In]MP2653 and one antagonist [{sup 99m}Tc]Demobesin-1 were evaluated in GRPR-overexpressing human PC-3 tumour-bearing mice to determine peptide stability in vivo, biodistribution and GRPR targeting potential by animal SPECT/CT imaging and ex vivo autoradiography. HPLC analysis of blood showed intact Demobesin-1 at 5 and 15 min after injection (64.1{+-}1.6% and 41.0{+-}01%, respectively) being much less for the other compounds. AMBA, the second most stable analogue, showed 36.1{+-}2.7% and 9.8{+-}1.1% intact peptide after 5 and 15 min. PC-3 tumour uptake at 1 h was comparable for Demobesin-1, AMBA, PESIN and MP2346 (3.0{+-}0.4, 2.7{+-}0.5, 2.3{+-}0.5 and 2.1{+-}0.9%ID/g, respectively), but very low for MP2653 (0.9 {+-} 0.2%ID/g). In addition, MP2346 showed undesirably high uptake in the kidneys (7.9{+-}1.9%ID/g) being significantly less for the other analogues. AMBA, MP2346 and PESIN revealed favourable increases in tumour to blood ratios over time while changes in tumour to kidney and pancreas ratios for Demobesin-1 from 1 to 24 h after injection were

Recent changes in Brazilian legislation for commercial disinfectants have been published due to the recent epidemic of nosocomial infections caused by rapidly growing mycobacteria (RGM) in many states of Brazil over the last 8years. One of these documents requires that all the manufacturers provide evidence of efficacy of sterilizing and disinfectant products, used for semi critical medical devices, against the Mycobacterium bovis BCG Moreau and Mycobacterium abscessus subsp. bolletii INCQS 00594 strains by using the Confirmative in vitro Test for Determining Tuberculocidal Activity of Disinfectants recommended by the Association of Official Analytical Chemists. These changes have caused additional costs and increased problems for importation of enrichment products at national laboratories where disinfectant efficacy assay service is performed. Middlebrook ADC Enrichment (ADC) is provided by a unique manufacturer and used in the official protocol. The aim of the present study was to evaluate an alternative in house low-cost enrichment composed of fetal bovine serum and glucose (FBSG) with ADC for performance of disinfectant efficacy assay against mycobacteria. After obtaining the growth curves for M. abscessus ATCC 19977, M. abscessus subsp. bolletii INCQS 00594, Mycobacterium chelonae ATCC 35752, and Mycobacterium fortuitum ATCC 6841 by using ADC enrichment and FBSG in Kirchners and 7H9 culture media. Through statistical analysis via the Kruskal-Wallis test on the evaluation of microorganism growth rate, it was observed that there was no inhibition of RGM growth by any of the enrichments used. These results suggest that low-cost enrichment FBSG may be used as a potential substitute of ADC for composition of media for mycobacterial growth, including in disinfectant tests.

The comparative efficacy and safety profiles of selected daily 1000 IU, weekly 7000 IU and monthly 30,000 IU vitamin D 3 -not previously investigated-will be evaluated. Here, a prospective, randomized clinical trial, comparing efficacy and safety of a daily single dose of 1000 IU (group A) to a once-weekly 7000 IU dose (group B), or monthly 30,000 IU dose (group C) of vitamin D 3 . The present study is a controlled, randomized, open-label, multicenter clinical trial, 3  months in duration. Sixty-four adult subjects with vitamin D deficiency (25OHD<20 ng/ml), were included according to the inclusion and exclusion criteria. Dose-responses for increases in serum vitamin 25OHD were statistically equivalent for each of the three groups: A, B and C. Outcomes were 13.0 ± 1.5; 12.6 ± 1.1 and 12.9 ± 0.9 ng/ml increases in serum 25OHD per 1000 IU, daily, weekly and monthly, respectively. The treatment of subjects with selected doses restored 25OHD values to levels above 20 ng/ml in all groups. Treatment with distinct administration frequency of vitamin D 3 did not exhibit any differences in safety parameters. The daily, weekly and monthly administrations of daily equivalent of 1000 IU of vitamin D 3 provide equal efficacy and safety profiles.

The success of a dandruff treatment depends not only on the ability of a shampoo to control dandruff, but also on patient compliance, which is closely linked to the cosmetic attributes of the product. The aim of this study was to compare efficacy, tolerance, and cosmetic properties of a LHA Shampoo [containing 0.1% lipohydroxy acid (LHA) and 1.3% salicylic acid] to a CPO shampoo [containing 1.5% ciclopiroxolamine (CPO), 3% salicylic acid, and 0.5% menthol] in subjects with seborrheic dermatitis (SD) of the scalp. One hundred subjects with mild to moderate scalp SD were randomized to receive either the LHA shampoo or the CPO shampoo every 2 days for 4 weeks. Efficacy and tolerance were evaluated at days 0, 14, and 28. The LHA and the CPO shampoo both decreased symptoms of scale, erythema, itching, cutaneous discomfort, and dryness from baseline to day 28. A higher percentage of patients showed improvement in the group treated with the LHA formulation than in the group treated with the CPO formulation, but the difference did not reach statistical significance. At day 28, the tolerance and the global efficacy of the LHA shampoo were significantly better (P = 0.03 and P = 0.01, respectively) than those of the CPO shampoo. Furthermore, the cosmetic acceptability was better or significantly better for all the endpoints evaluated for the LHA shampoo (P = 0.02 for cleaning, P = 0.04 for lathering). In conclusion, these results demonstrated that the lipohydroxy acid shampoo evaluated in this study is a more convenient, efficient, safe, and well-tolerated cosmetic treatment for mild-to-moderate seborrheic dermatitis of the scalp than a ciclopiroxolamine shampoo.

Piezosurgery is a relatively new osteotomy technique using microvibrations of scalpels at ultrasonic frequencies to perform safe and effective osteotomies without damage to adjacent soft tissue, which is widely used in spinal, oral, and maxillofacial surgery. We hypothesized that such a device could also be useful in cervical laminoplasty. The purpose of this study was to compare the safety and efficacy of a piezosurgery device with those of a highspeed drill in cervical laminoplasty. A prospectively randomized clinical study was designed. Forty-two consecutive patients were enrolled in the study. All patients underwent modified expansive open-door laminoplasty and were randomly divided into 2 groups according to the instrument for transection of the lamina, using high-speed drill (drill group) or piezosurgery device (piezosurgery group). The operation time, intraoperative blood loss, and postoperative drainage were recorded. Japanese Orthopedic Association (JOA) score and visual analogue scale (VAS) as clinical assessments were quantified. No significant difference was observed in the operation time between the 2 groups. In the piezosurgery group, there were less loss of the intraoperative blood and postoperative drainage compared with the drill group. However, clinical results (VAS and JOA scores) showed no significant difference between both groups during the all follow-up periods. The piezosurgery is a useful instrument and at least as safe and efficacious as the conventional high-speed drill in cervical laminoplasty.

Systematic literature review and meta-analysis. To evaluate studies that used arthritis self-management education alone or with exercise to improve Arthritis Self-Efficacy Scale scores of patients with knee osteoarthritis. Increasing self-efficacy may improve patient knee osteoarthritis symptom management and function. MEDLINE (1946-March 2013), CINAHL (1981-March 2013), and PsycINFO (1967-March 2013) databases were searched. Twenty-four studies, including 3163 subjects (women, n = 2547 [80.5%]; mean ± SD age, 65.3 ± 6.5 years), met the inclusion criteria. A meta-analysis was performed to compare the standardized mean difference effect sizes (Cohen d) of randomized controlled studies that used the Arthritis Self-Efficacy Scale pain (13 studies, n = 1906), other symptoms (13 studies, n = 1957), and function (5 studies, n = 399) subscales. Cohen d effect sizes were also calculated for cohort studies that used the Arthritis Self-Efficacy Scale pain (10 studies, n = 1035), other symptoms (9 studies, n = 913), and function (3 studies, n = 141) subscales. Both randomized controlled studies and cohort studies were grouped by intervention type (intervention 1, arthritis self-management education alone; intervention 2, arthritis self-management education with exercise), and effect sizes were compared (Mann-Whitney U tests, Pmanagement education with exercise displayed higher methodological quality scale scores (76.8 ± 13.1 versus 61.6 ± 19.6, P = .03). Statistically significant standardized effect-size differences between intervention 1 and intervention 2 were not observed. Small to moderate effect sizes were observed regardless of whether the intervention included exercise. Exercise interventions used in conjunction with arthritis self-management education programs need to be developed to better enhance the self-efficacy of patients with knee osteoarthritis.

This study was designed to compare the therapeutic and residual efficacy for 1 month of three topical ectoparasiticides on mixed-bred dogs against the brown dog tick, Rhipicephalus sanguineus. Adult dogs (n = 32, 10.8-18.4 kg BW) were allocated to 4 groups (n = 8) and infested with 50 adult ticks on days -8, -2, 7, 14, 21, and 28. Within each group, dogs were treated topically on day 0 with a control solution (CS), Vectra 3D (DPP), Frontline Plus (FM), or K9 Advantix (IP). Ticks were enumerated on dogs 24 h after treatment and each subsequent tick infestation by in situ thumb count assessment without removal and at 48 h by combing and removal. Acaricidal efficacy was calculated using arithmetic means for all 24 and 48 h tick count assessments. From 42 to 56% of the total, infested ticks were found on dogs 48 h post-challenge in the CS group. Therapeutic efficacy for all treatments ranged from 45.5 to 64.6% after 48 h of infestation. Residual efficacy after FM treatment was consistently lower compared to DPP or IP treatments at the 24 h assessments on days 8, 22, 23, and 29. Residual efficacy measured at this last time point was 94.8% for DPP, 83.1% for IP, and 46.9% for FM. This study demonstrates that permethrin-based formulations (DPP and IP) provided a quicker onset of residual protection against brown dog ticks compared to FM. Although DPP and IP are both permethrin-based formulations, DPP exhibited consistently higher residual acaricidal efficacies and was the only treatment that provided >90% protection for 1 month at 24 h post challenge.

The comparative efficacy of the three mumps vaccine strains (Jeryl-Lynn, Urabe and Rubini) was conducted in an Asian population from data arising from an epidemiological investigation of seven institutional outbreaks of mumps in Singapore. Demographic information (gender, age, ethnic group), clinical presentation and vaccination history (date and place of mumps vaccination, type of mumps vaccine received) of all children who attended the six childcare centres and one primary school where outbreaks of 20 or more cases of mumps occurred in 1999 were collected. The attack rate of the unvaccinated group and the attack rates of the vaccine groups (for each vaccine strain) were determined and the vaccine efficacy of the three vaccines calculated. The vaccine efficacy of the Jeryl-Lynn strain, Urabe strain and Rubini strain mumps vaccine were 80.7, 54.4 and -55.3%, respectively. Rubini strain mumps vaccine conferred no protection and has since been deregistered in Singapore.

Full Text Available Abstract The effect of iron fortification is generally assumed to be less than iron supplementation; however, the magnitude of difference in effects is not known. The present study aims to compare the efficacy of these two strategies on anaemia and iron status. After screening on low Hb, 425 anaemic children in six primary schools in Tam Nong district of Phu Tho province were included in a randomized, placebo-controlled trial comparing two groups receiving iron fortified instant noodles or iron supplementation for 6 months and a control group, with children in all groups having been dewormed. Blood samples were collected before and after intervention for haemoglobin, serum ferritin (SF, serum transferrin receptor (TfR, C-reactive protein (CRP, and haemoglobinopathies analysis. Regression analysis was used to assess the effect of iron fortification and iron supplementation on haemoglobin concentration, SF, TfR, body iron, and anaemic status as outcome variables. The improvement of haemoglobin, SF, and body iron level in the group receiving iron fortification was 42% (2.6 g/L versus 6.2 g/L, 20% (23.5 μg/L versus 117.3 μg/L, and 31.3% (1.4 mg/kg versus 4.4 mg/kg of that in the iron supplementation group. The prevalence of anaemia dropped to 15.1% in the control group, with an additional reduction of anaemia of 8.5% in the iron supplementation group. The additional reduction due to iron fortification was 5.4%, which amounts to well over 50% of the impact of supplementation. In conclusion, the efficacy of iron fortification based on reduction of prevalence of anaemia, and on the change in haemoglobin level, is about half of the maximum impact of supplementation in case of optimal compliance. Thus, in a population of anaemic children with mild iron deficiency, iron fortification should be the preferred strategy to combat anaemia.

Full Text Available Background: Platelet concentrates are used in various medical procedures to promote soft- and hard-tissue regeneration. In recent times, their antimicrobial efficacy is also explored. However, various platelet concentrates have evolved which differ in the centrifugation protocols. One such recently introduced platelet concentrate is injectable platelet-rich fibrin (i-PRF concentrate. Hence, the aim was to evaluate the antimicrobial property, and platelet count of i-PRF in comparison to other platelet concentrates, i.e., PRF, platelet-rich plasma (PRP, and control (whole blood. Materials and Methods: Blood samples were obtained from 10 chronic generalized marginal gingivitis patients. Platelet concentrates were prepared using standardized centrifugation protocol. Platelet count was evaluated by manual counting method using smear preparation of each sample. Subsequently, antimicrobial activity against oral bacteria was examined on blood agar using disc diffusion method to quantify the inhibitory effects. Results: Statistical significance was analyzed by one-way analysis of variance (ANOVA. P 0.05. i-PRF showed statistically significant difference (P < 0.001 in platelet count when compared to control. It was also significant when compared to PRP (P < 0.01, PRF (P < 0.001. Conclusion: i-PRF has maximum antimicrobial efficacy and higher platelet count in comparison to other platelet concentrates, thereby indicating to have a better regenerative potential then others.

Full Text Available Aim: To assess the efficacy of topical negative pressure moist wound dressing as compared to conventional moist wound dressings in improving the healing process in chronic wounds and to prove that negative pressure dressings can be used as a much better treatment option in the management of chronic wounds. Materials and Methods: This is a prospective comparative study of data from 112 patients with chronic wounds, of which 56 patients underwent topical negative pressure dressings (17 diabetic, 10 pressure sores, nine ischemic, two varicose, 10 post-infective raw areas and eight traumatic - six had bone exposed, two orthopaedic prosthesis exposed. The remaining 56 patients underwent conventional moist dressings (20 diabetic, two ischemic, 15 pressure sores, three varicose, eight post-infective raw areas and eight traumatic - five had bone exposed, three orthopaedic prosthesis exposed. The results were compared after 10 days. The variables compared were, rate of granulation tissue formation as a percentage of ulcer area covered, skin graft take up as the percentage of ulcer surface area and duration of hospital stay. The variables were compared using Unpaired Student′s t test. A " P" value < 0.05 was considered significant. Results: Out of 56 patients who underwent topical negative pressure dressings, six (10.71% were failures, due to failure in maintaining topical negative pressure due to defective sealing technique; these were included into the study group. After 10 days, the mean rate of granulation tissue formation was 71.43% of ulcer surface area. All these 56 cases underwent split-thickness skin grafting. The mean graft take-up was 79.29%. The mean hospital stay was 32.64 days. In the remaining 56 patients, the mean rate of granulation tissue formation was 52.85% of ulcer surface area. The mean graft take-up was only 60.45% of the total ulcer surface area. The mean hospital stay was 60.45 days. Conclusion: To conclude, topical negative

Full Text Available In the past few decades, copper based biocides have been extensively used in food crop protection including citrus, small fruits and in all garden vegetable production facilities. Continuous and rampant use of copper based biocides over decades has led to accumulation of this metal in the soil and the surrounding ecosystem. Toxic levels of copper and its derivatives in both the soil and in the run off pose serious environmental and public health concerns. Alternatives to copper are in great need for the agriculture industry to produce food crops with minimal environmental risks. A combination of copper and zinc metal containing biocide such as Nordox 30/30 or an improved version of zinc-only containing biocide would be a good alternative to copper-only products if the efficacy can be maintained. As of yet there is no published literature on the comparative study of the materials characteristics and phyto-compatibility properties of copper and zinc-based commercial products that would allow us to evaluate the advantages and disadvantages of both versions of pesticides. In this report, we compared copper hydroxide and zinc oxide based commercially available biocides along with suitable control materials to assess their efficacy as biocides. We present a detailed material characterization of the biocides including morphological studies involving electron microscopy, molecular structure studies involving X-ray diffraction, phytotoxicity studies in model plant (tomato and antimicrobial studies involving surrogate plant pathogens (Xanthomonas alfalfae subsp. citrumelonis, Pseudomonas syringae pv. syringae and Clavibacter michiganensis subsp. michiganensis. Zinc based compounds were found to possess comparable to superior antimicrobial properties while exhibiting significantly lower phytotoxicity when compared to copper based products thus suggesting their potential as an alternative.

The present study examined the interrelationships between motivation orientation (intrinsic and extrinsic), self-efficacy (in reading academic texts and essay writing), and approaches to studying (deep, strategic, and surface). The study also examined changes in approaches to studying over time. A total of 163 first-year undergraduate students in psychology at a UK university took part in the study. Participants completed the Work Preference Inventory motivation questionnaire, self-efficacy in reading and writing questionnaires and the short version of the Revised Approaches to Study Inventory. The results showed that both intrinsic and extrinsic motivation orientations were correlated with approaches to studying. The results also showed that students classified as high in self-efficacy (reading and writing) were more likely to adopt a deep or strategic approach to studying, while students classified as low in self-efficacy (reading and writing) were more likely to adopt a surface approach. More importantly, changes in students' approaches to studying over time were related to their self-efficacy beliefs, where students with low levels of self-efficacy decreased in their deep approach and increased their surface approach across time. Students with high levels of self-efficacy (both reading and writing) demonstrated no such change in approaches to studying. Our results demonstrate the important role of self-efficacy in understanding both motivation and learning approaches in undergraduate students. Furthermore, given that reading academic text and writing essays are essential aspects of many undergraduate degrees, our results provide some indication that focusing on self-efficacy beliefs amongst students may be beneficial to improving their approaches to study.

This study aims to determine the role of mixing techniques of polyether impression materials and efficacy of disinfection on microbial colonization of these impression materials. Polyether impression material was mixed using two methods: First by hand mixing (group I) and second using an automixer (group II) with a total of 100 samples. Four microbial strains were studied, which included Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. After incubation, the bacterial colonies were counted, and then, disinfectant solution was applied. The effect of disinfection solution was evaluated for each specimen. The surface of polyether impression materials mixed with an automixer has less number of voids and overall a smoother surface as compared with the hand-mixed ones. On comparing the disinfection procedures, i.e., specimens without any disinfection and specimens after disinfection, statistically highly significant difference was seen between all the groups. We can conclude that impression mixing procedures are important in determining the surface characteristics of the impression and ultimately the colonization of bacteria and also determine the importance of disinfection on microbial colonization. This study emphasises the deleterious role of nosocomial infections and specific measures that should be taken regarding the prevention of such diseases. Dental impressions are proved to be a source of such infections and may lead to transmission of such diseases. Thus, proper measures should be taken right from the first step of impression taking to minimizing and preventing such kind of contaminations in clinical practice.

Self-efficacy is increasingly being recognized as an important factor to consider in medical research, especially in different pain conditions such as whiplash-associated disorders (WAD). When pain is not effectively treated or relieved, it may negatively affect patients' life situation and cause a decline in perceived self-efficacy. Knowledge of what level of self-efficacy can be considered an actual deficit in patients with WAD is, however, sparse. The purpose of this study is to analyze whether subacute WAD has an impact on self-efficacy beliefs. A cohort study was designed to identify the impact of WAD on self-efficacy beliefs. The exposed group consisted of 47 patients with subacute WAD following a whiplash trauma. The control group representing the general population consisted of 212 participants, and was randomly selected to match the distribution of age and sex in the exposed group. The Self-Efficacy Scale was used to assess the individuals' confidence in their ability to successfully carry out activities of daily living. In the exposed group, 47 responded (100%), and in the control group, 113 (53%) responded. The results show that the total scores on the Self-Efficacy Scale were significantly lower in the exposed group compared with the control group, concerning both the mean (P<0.001) and median (P<0.001) scores. In conclusion, patients with subacute WAD experience a decline in functional self-efficacy, which stresses the importance of incorporating these beliefs in clinical practice and research.

Full Text Available Abstract Background Psychostimulants and non stimulants are effective in the treatment of ADHD. Efficacy of both methylphenidate and atomoxetine has been established in placebo controlled trials. Direct comparison of efficacy is now possible due to availability of results from several head-to-head trials of these two medications. Methods All published, randomized, open label or double blind trials, comparing efficacy of methylphenidate with atomoxetine, in treatment of ADHD in children, diagnosed using DSM-IV™ criteria were included. The outcome studied was ADHDRS-IVParent:Inv score. The standardized mean difference (SMD was used as a measure of effect size. Results Nine randomized trials comparing methylphenidate and atomoxetine, with a total of 2762 participants were included. Meta-analysis did not find a significant difference in efficacy between methylphenidate and atomoxetine (SMD = 0.09, 95% CI -0.08-0.26 (Z = 1.06, p = 0.29. Synthesis of data from eight trials found no significant difference in response rates (RR = 0.93 95% CI 0.76-1.14, p = 0.49. Sub group analysis showed a significant standardized mean difference favouring OROS methylphenidate (SMD = 0.32, 95% CI 0.12-0.53 (Z = 3.05, p I2 = 67%. Subgroup analysis demonstrated the heterogeneity to be due to the open label trials (p = 0.001, I2 = 81%. Conclusions In general atomoxetine and methylphenidate have comparable efficacy and equal acceptability in treatment of ADHD in children and adolescents. However OROS methylphenidate is more effective than atomoxetine and may be considered as first line treatment in treatment of ADHD in children and adolescents.

To compare the pharmacokinetics (PK), safety and efficacy of innovator infliximab (INX) and CT-P13, a biosimilar to INX, in patients with active ankylosing spondylitis (AS). Phase 1 randomised, double-blind, multicentre, multinational, parallel-group study. Patients were randomised to receive 5 mg/kg of CT-P13 (n=125) or INX (n=125). Primary endpoints were area under the concentration-time curve (AUC) at steady state and observed maximum steady state serum concentration (Cmax,ss) between weeks 22 and 30. Additional PK, efficacy endpoints, including 20% and 40% improvement response according to Assessment in Ankylosing Spondylitis International Working Group criteria (ASAS20 and ASAS40), and safety outcomes were also assessed. Geometric mean AUC was 32 765.8 μgh/ml for CT-P13 and 31 359.3 μgh/ml for INX. Geometric mean Cmax,ss was 147.0 μg/ml for CT-P13 and 144.8 μg/ml for INX. The ratio of geometric means was 104.5% (90% CI 94% to 116%) for AUC and 101.5% (90% CI 95% to 109%) for Cmax,ss. ASAS20 and ASAS40 responses at week 30 were 70.5% and 51.8% for CT-P13 and 72.4% and 47.4% for INX, respectively. In the CT-P13 and INX groups more than one adverse event occurred in 64.8% and 63.9% of patients, infusion reactions occurred in 3.9% and 4.9%, active tuberculosis occurred in 1.6% and 0.8%, and 27.4% and 22.5% of patients tested positive for anti-drug antibodies, respectively. The PK profiles of CT-P13 and INX were equivalent in patients with active AS. CT-P13 was well tolerated, with an efficacy and safety profile comparable to that of INX up to week 30.

Full Text Available The common aim of transcranial stimulation methods is the induction or alterations of cortical excitability in a controlled way. Significant effects of each individual stimulation method have been published; however, conclusive direct comparisons of many of these methods are rare. The aim of the present study was to compare the efficacy of three widely applied stimulation methods inducing excitability enhancement in the motor cortex: 1 mA anodal transcranial direct current stimulation (atDCS, intermittent theta burst stimulation (iTBS, and 1 mA transcranial random noise stimulation (tRNS within one subject group. The effect of each stimulation condition was quantified by evaluating motor-evoked-potential amplitudes (MEPs in a fixed time sequence after stimulation. The analyses confirmed a significant enhancement of the M1 excitability caused by all three types of active stimulations compared to sham stimulation. There was no significant difference between the types of active stimulations, although the time course of the excitatory effects slightly differed. Among the stimulation methods, tRNS resulted in the strongest and atDCS significantly longest MEP increase compared to sham. Different time courses of the applied stimulation methods suggest different underlying mechanisms of action. Better understanding may be useful for better targeting of different transcranial stimulation techniques.

Onchocerciasis (river blindness), caused by the filarial nematode Onchocerca volvulus, is a major cause of visual impairment and dermatitis in sub-Saharan Africa. As O. volvulus contains an obligatory bacterial symbiont (Wolbachia), it is susceptible to antibiotic chemotherapy, although current regimens are considered too prolonged for community-level control programs. The aim of this study was to compare the efficacies of oxytetracycline and rifampin, administered separately or in combination, against a close relative of O. volvulus (Onchocerca ochengi) in cattle. Six animals per group were treated with continuous or intermittent oxytetracycline regimens, and effects on adult worm viability, dermal microfilarial loads, and Wolbachia density in worm tissues were assessed. Subsequently, the efficacies of 3-week regimens of oxytetracycline and rifampin alone and a combination regimen were compared, and rifampin levels in plasma and skin were quantified. A 6-month regimen of oxytetracycline with monthly dosing was strongly adulticidal, while 3-week and 6-week regimens exhibited weaker adulticidal effects. However, all three regimens achieved >2-log reductions in microfilarial load. In contrast, rifampin monotherapy and oxytetracycline-rifampin duotherapy failed to induce substantive reductions in either adult worm burden or microfilarial load, although a borderline effect on Wolbachia density was observed following duotherapy. Dermal rifampin levels were maintained above the MIC for >24 h after a single intravenous dose. We conclude that oxytetracycline-rifampin duotherapy is less efficacious against O. ochengi than oxytetracycline alone. Further studies will be required to determine whether rifampin reduces oxytetracycline bioavailability in this system, as suggested by human studies using other tetracycline-rifampin combinations.

Does Digital Game Interactivity Always Promote Self-Efficacy?

Science.gov (United States)

Lee, Yu-Hao

2015-11-01

Interactive digital games can promote self-efficacy by engaging players in enactive and observational learning. However, interactivity does not always lead to greater self-efficacy. Important constructs in social cognitive theory, such as performance outcome and perceived similarity, are often not accounted for in studies that have tested the effect of digital game interactivity on self-efficacy. This study assessed the effects of interactive digital games compared with passive digital games based on video comparison, a common experimental design used to test the effect of digital game interactivity on self-efficacy. In addition, this study also evaluated player performance and measured perceived similarity to the observed player. Findings suggested that in general, digital game interactivity predicted higher self-efficacy compared with noninteractive passive games. However, in the noninteractive conditions, the effects of performance on self-efficacy were moderated by perceived similarity between the observer and the observed player. When the observed player was perceived to be similar to the observer, the effects of performance on self-efficacy were comparable to the interactive game, but when the observed player was perceived as dissimilar to the observer, observing the dissimilar player failed to increase observer self-efficacy. Implications for interactivity manipulations and game developers are discussed.

In this study, we aimed to investigate the efficacy of combined orthodontic-periodontic treatment in the treatment of patients with periodontitis and its effects on the levels of inflammatory cytokines. A total of 117 patients with periodontitis were randomly assigned to the basic group (receiving basic periodontic treatment, n = 58) and the combined group (receiving combined orthodontic-periodontic treatment, n = 59). In addition, 52 healthy people without periodontal disease were selected as the normal group. Probing depth, tooth mobility, plaque index, clinical attachment level, and sulcus bleeding index were recorded. ELISA was applied to detect gingival crevicular fluid (GCF) and serum levels of inflammatory cytokines. A 2-year clinical follow-up was conducted. Before treatment, the periodontal parameters (probing depth, tooth mobility, plaque index, clinical attachement level, and sulcus bleeding index) and GCF and serum levels of inflammatory cytokines (high-sensitivity C-reactive protein, interleukin-1β, interleukin-5, interleukin-6, interleukin-8, tumor necrosis factor-α, and prostaglandin E2) in the combined and basic groups were higher than those in the normal group. After 6 and 18 months of treatment, the periodontal parameters and GCF and serum levels of inflammatory cytokines decreased in the combined and basic groups. The periodontal parameters and the GCF and serum levels of inflammatory cytokines in the combined group were significantly lower than those in the basic group after 18 months of treatment. The combined group had a lower recurrence rate compared with the basic group. Combined orthodontic-periodontic treatment had good clinical efficacy in the treatment of periodontitis and could effectively decrease the levels of inflammatory cytokines.

2008-01-01

Full Text Available Background: Several modalities of treatment have been tried in vitiligo with varied results; however, Indian data on comparative studies of two or more therapies are limited. Aims: We compared different phototherapy methods with an oral steroid as an adjunct to determine the method with the best tolerability and efficacy. Methods: Eighty-six patients with progressive vitiligo were randomly assigned to different study groups according to a continuous selection method over a period of one year. Group 1 was given OMP + PUVA, group 2 OMP + UVB (NB, group 3 OMP + UVB (BB and group 4 was given OMP alone. Each patient was followed up for six months and then released from treatment. Clinical evaluation was made at the end of three and six months. Results: In group 1 (OMP + PUVA, marked improvement was seen in 18.51% while moderate improvement was seen in 66.66% of the patients. Marked improvement was seen in 37.03% in group 2 (OMP + NB-UVB while 44.44% had moderate improvement. In group 3 (OMP + BB UVB, 8.33% showed marked improvement while moderate improvement was seen in 25% of the patients. Marked and moderate improvement was seen in 5 and 10% of group 4 (OMP patients, respectively. Conclusions: Our study compared four treatment modalities in vitiligo patients, out of which oral minipulse of steroids (OMP only had an adjunct value and was not very effective by itself. Narrow band UVB has a definite edge over broad band UVB and should be preferred when both options are available. NB-UVB and PUVA showed comparable efficacy.

Introduction. This study prospectively evaluates and compares the treatment efficacy of botulinum toxin injection under electromyography guidance (EMG group) and percutaneous botulinum toxin injection under flexible fiberscopic guidance (fiberscopy group). Methods. Thirty patients with adductor spasmodic dysphonia (ADSD), who had never received treatment, were randomly allocated into EMG- or fiberscopy-guided botulinum toxin injections between March 2008 and February 2010. We assessed acoustic and aerodynamic voice parameters, and the voice handicap index (VHI) before injection and at 1, 3, and 6 months after injection. Results. The mean total dosage of botulinum toxin was similar for both groups: 1.7 ± 0.5 U for the EMG group and 1.8 ± 0.4 U for the fiberscopy group (P > 0.05). There were no significant differences in outcomes between the two groups in either the duration of effectiveness or complications such as breathy voice and aspiration. Conclusion. Botulinum toxin injection under fiberscopic guidance is a viable alternative to EMG-guided botulinum toxin injection for the treatment of adductor spasmodic dysphonia when EMG equipment is unavailable.

Schaubroeck, J; Lam, S S; Xie, J L

2000-08-01

This study examined how cultural differences and efficacy perceptions influence the role of job control in coping with job demands. Perceiving higher control mitigated the effects of demands on psychological health symptoms and turnover intentions only among American bank tellers reporting high job self-efficacy. Among American tellers reporting low job self-efficacy, perceived control exacerbated the effects of demands. However, in a matched Hong Kong sample, collective efficacy interacted in the same way with control and demands as job self-efficacy had in the American sample. These differences appear to be explained by the individual attributes of idiocentrism and allocentrism that are linked to the societal norms of individualism and collectivism, respectively.

Although the Dedicated Education Unit (DEU) has shown initial promise related to satisfaction with the teaching/learning environment, few studies have examined student outcomes related to the use of the DEU as a clinical education model beyond student satisfaction. The purpose of this quantitative, quasi-experimental study was to compare student outcomes from the traditional clinical education (TCE) model with those from the DEU model. Participants were students enrolled in a four-year baccalaureate program in nursing (n = 193) who had clinical education activities in one of three clinical agencies. Participants were assigned to either the DEU or a TCE model. Pre-clinical and post-clinical self-efficacy scores were measured for each group using an adapted Generalized Self-Efficacy Scale (Schwarzer and Jerusalem, 1995). Both groups experienced a significant increase in self-efficacy scores post clinical education. The increase in self-efficacy for the DEU students was significantly greater than the increase in self-efficacy for the traditional students. Self-efficacy is considered an important outcome of nursing education because high self-efficacy has been linked to making an easier transition from student to nursing professional. This study supports the quality of the DEU as a clinical education model by examining student self-efficacy outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

The acaricidal efficacy of afoxolaner (NexGard(®), Merial) was evaluated against Sarcoptes scabiei var. canis in a field efficacy study, when administered orally at a minimum dose of 2.5 mg/kg to dogs naturally infested with the mites. Twenty mixed-breed dogs of either sex (6 males and 14 females), aged over 6 months and weighing 4-18 kg, were studied in this randomised controlled field efficacy trial. Dogs, naturally infested with Sarcoptes scabiei var. canis confirmed by skin scrapings collected prior to allocation, were randomly divided into two equal groups. Dogs in Group 1 were not treated. Dogs in Group 2 were treated on Days 0 and 28. On Days 0 (pre-treatment), 28 (pre-treatment) and 56, five skin scrapings of similar size were taken from different sites with lesions suggestive of sarcoptic mange. The extent of lesions was also recorded on Days 0, 28 and 56, and photographs were taken. Dogs treated orally with afoxolaner had significantly (p dogs at these times (100% efficacy based on mite counts).

Oba, Yuji; Lone, Nazir A

2014-01-01

A combination therapy with inhaled corticosteroid (ICS) and a long-acting beta agonist (LABA) is recommended in severe chronic obstructive pulmonary disease (COPD) patients experiencing frequent exacerbations. Currently, there are five ICS/LABA combination products available on the market. The purpose of this study was to systematically review the efficacy of various ICS/LABA combinations with a network meta-analysis. Several databases and manufacturer's websites were searched for relevant clinical trials. Randomized control trials, at least 12 weeks duration, comparing an ICS/LABA combination with active control or placebo were included. Moderate and severe exacerbations were chosen as the outcome assessment criteria. The primary analyses were conducted with a Bayesian Markov chain Monte Carlo method. Most of the ICS/LABA combinations reduced moderate-to-severe exacerbations as compared with placebo and LABA, but none of them reduced severe exacerbations. However, many studies excluded patients receiving long-term oxygen therapy. Moderate-dose ICS was as effective as high-dose ICS in reducing exacerbations when combined with LABA. ICS/LABA combinations had a class effect with regard to the prevention of COPD exacerbations. Moderate-dose ICS/LABA combination therapy would be sufficient for COPD patients when indicated. The efficacy of ICS/LABA combination therapy appeared modest and had no impact in reducing severe exacerbations. Further studies are needed to evaluate the efficacy of ICS/LABA combination therapy in severely affected COPD patients requiring long-term oxygen therapy.

A study of self-efficacy in job-related context

Directory of Open Access Journals (Sweden)

Špela Frlec

2005-04-01

Full Text Available The article stems from an attempt to transfer the Bandura's social cognitive theory into organisational praxis. Beliefs of self-efficacy, which is defined as people's judgments of their capabilities to organize and execute courses of action required to attain designated types of performances, are constructed from 4 principal sources of information: enactive mastery experiences; vicarious experiences that alter efficacy beliefs through transmission of competencies and comparison with the attainment of others; verbal persuasion and allied types of social influences that one possesses certain capabilities; and physiological and affective states from which people partly judge their capableness, strength, and vulnerability to dysfunction. The study of self-efficacy in job-related context involved 295 employees from 3companies belonging to the same business group. Self-efficacy was assed using Schwarzer's scale, while rating scales were used for assessing the 4 principal sources of influence upon it. First, differences between companies regarding demographic characteristics of the employees, job characteristics and self-efficacy were analyzed. Dependence of employee's self-efficacy on his/her age, gender, education, work experience, employment status, job type and the four principal influence sources was tested using a regression model. Finally, we identified typical employee profiles with respect to the studied factors. We hope that our study will help human-resources specialists design appropriate interventions for developing a resilient sense of self-efficacy in the employees.

Cochrane Library (CENTRAL), PubMed/MEDLINE, EMBASE and PsycINFO were searched from inception to January 15, 2018 for randomized controlled trials (RCTs) comparing anti-diabetic agents with placebo and/or another active anti-diabetic agent for the treatment of AD or MCI. Nineteen eligible studies (n = 4,855) evaluating the effects of six different anti-diabetic drugs (i.e., intranasal insulin, pioglitazone, rosiglitazone, metformin, sitagliptin and liraglutide) were included. The results of 29 pairwise comparisons indicated that cognition was significantly improved in subjects treated with anti-diabetic agents compared to placebo. Pioglitazone 15-30 mg demonstrated the greatest efficacy compared to placebo in network meta-analysis. No significant differences in acceptability were identified when comparing agents with each other and with placebo. The current findings indicate a pro-cognitive class effect of anti-diabetic agents in AD/MCI. Other anti-diabetic agents should also be investigated in future studies.

The aim of this in vitro study was to compare the efficacy of two retreatment rotary systems in the removal of Gutta-percha (GP) and sealer from the root canal walls with or without solvent. Forty-eight extracted human mandibular first premolars were prepared and obturated with GP and AH Plus sealer. Samples were then randomly divided into four groups. Group I was retreated with MtwoR rotary system without solvent, Group II was retreated with MtwoR rotary system with Endosolv R as the solvent, Group III with D-RaCe rotary system without solvent, and Group IV with D-RaCe rotary system and Endosolv R solvent. The cleanliness of canal walls was determined by stereomicroscope (×20) and AutoCAD software. Kruskal-Wallis test and Mann-Whitney U-test were used to compare the data. Results showed that none of the retreatment systems used in this study was able to completely remove the root canal filling material. D-RaCe with or without solvent showed significantly ( P > 0.05) less filling material at all levels compared to MtwoR with/without solvent. Within the limitation of the current study, D-RaCe rotary retreatment system is more effective in removing filling material from root canal walls when compared to MtwoR rotary retreatment system.

To instrumentally evaluate the efficacy and the safety of a new ternary system chemo exfoliating formulation (water-dimethyl isosorbide-acid) vs traditional binary systems (water and acid) where the acid is maintained in both the systems at the same concentration. Different peelings (binary system pyruvic acid and trichloroacetic acid-TCA, and ternary system pyruvic acid and TCA) were tested on the volar forearm of 20 volunteers of both sexes between 28 and 50 years old. The outcomes were evaluated at the baseline, 10 minutes, 24 hours, and 1 week after the peeling by means of noninvasive skin diagnosis techniques. In vivo reflectance confocal microscopy was used for stratum corneum evaluation, transepidermal waterloss, and Corneometry for skin barrier and hydration, Laser Doppler velocimetry in association with colorimetry for irritation and erythema analysis. The instrumental data obtained showed that the efficacy and safety of the new ternary system peel compounds were significantly higher compared with the binary system formulations tested. The new formulation peels improved chemexfoliation and reduced complications such as irritation, redness, and postinflammatory pigmentation compared to the traditional aqueous solutions. The study showed that ternary system chemexfoliation, using a controlled delivery technology, was able to provide the same clinical effects in term of stratum corneum reduction with a significantly reduced barrier alteration, water loss, and irritation/erythema compared to traditional binary system peels. © 2017 Wiley Periodicals, Inc.

To compare the tolerability and efficacy of two titration methods (rapid and slow titration) for TOPINA Tablets with different dosages and periods of escalation, a double-blind comparative study was conducted in patients with localization-related epilepsy. A total of 183 patients were randomized to either rapid titration (initial dosage 100 mg/day increased by 100-200 mg at weekly intervals) or to slow titration (initial dosage 50 mg/day increased in 50 mg/day increments at weekly intervals). TOPINA Tablets were administered for 12 weeks to the maximum dosage of 400 mg/day. The incident of adverse events leading to treatment interruptions or withdrawals was 18.9% in rapid titration and 14.8% in slow titration, with no statistical significance (p = 0.554). The incident of adverse events and adverse reactions of slow titration was slightly lower than that of rapid titration. The common adverse events and adverse reactions reported in the two titration methods were comparable and were well tolerated. On the other hand, the efficacy of slow titration, percent reduction in seizure rate and responder rate, was comparable with that of rapid titration. In conclusion, there were no significant differences of therapeutic response to TOPINA Tablets between the two titration methods.

Eleven open multicentre studies were conducted to evaluate the efficacy of tioconazole cream 1% as a treatment for diaper rash with or without fungal (Candida) involvement, or impetigo in neonates and infants. In the dermal candidiasis/diaper rash group, 320 patients had either tioconazole (n = 220), a comparative imidazole (n = 43), or vehicle cream (n = 57) applied to the affected area twice daily. Twenty-one impetigo patients had only tioconazole cream 1% applied three times daily to lesions. The overall cure rate (patients with both clinical and mycological cure) at the end of treatment for tioconazole treated patients was 78%, for the comparative imidazole group it was 76% and for vehicle cream it was 39%. At the long-term follow-up evaluation approximately 6 weeks after treatment for patients with diaper rash, the overall cure rate was about the same in both tioconazole- and comparative imidazole-treated patients (87% and 90%, respectively), and 14% in patients using vehicle cream. Side-effects were coincident with disease symptoms and consisted primarily of erythema localized to the treatment area; they occurred in 5.4% (13/241) of the patients who received tioconazole and in 21% (9/43) of the patients who received comparative imidazole (econazole or miconazole). No side-effects were reported in this open study for the 57 patients who used vehicle cream. The results of these studies show that tioconazole cream 1% is safe and effective for the treatment of neonates and infants with dermal candidiasis, diaper rash and impetigo.

A non-immunosuppressive cyclosporin, SDZ PSC 833 (PSC833), shows a reversal effect on multidrug resistance (MDR) by functional modulation of MDR1 gene product, P-glycoprotein. The objective of the present study was to compare the reversal efficacy of three multidrug resistance modulators, PSC833, cyclosporin A (CsA) and verapamil (Vp). PSC833 has approximately 3-10-fold greater potency than CsA and Vp with respect to the restoring effect on reduced accumulation of doxorubicin (ADM) and vincristine (VCR) in ADM-resistant K562 myelogenous leukemia cells (K562/ADM) in vitro and also on the sensitivity of K562/ADM to ADM and VCR in in vitro growth inhibition. The in vivo efficacy of a combination of modifiers (PSC833 and CsA: 50 mg/kg, Vp 100 mg/kg administered p.o. 4 h before the administration of anticancer drugs) with anticancer drugs (ADM 2.5 mg/kg i.p., Q4D days 1, 5 and 9, VCR 0.05 mg/kg i.p., QD days 1-5) was tested in ADM-resistant P388-bearing mice. PSC833 significantly enhanced the increase in life span by more than 80%, whereas CsA and Vp enhanced by less than 50%. This reversal potency, which exceeded that of CsA and Vp, was confirmed by therapeutic experiments using colon adenocarcinoma 26-bearing mice. These results demonstrated that PSC833 has significant potency to reverse MDR in vitro and in vivo, suggesting that PSC833 is a good candidate for reversing multidrug resistance in clinical situations.

Currently, electronic cigarettes (e-cigarettes) are studied as though they are a homogeneous category. However, there are several noteworthy differences in the products that fall under this name, including potential differences in the efficacy of these products as smoking cessation aids. The current study examined the comparative efficacy of first- and second-generation e-cigarettes in reducing nicotine withdrawal symptoms in a sample of current smokers with little or no experience of using e-cigarettes. Twenty-two mildly to moderately nicotine-dependent individuals were randomized to a cross-over design in which they used first- and second-generation e-cigarettes on separate days with assessment of withdrawal symptoms directly prior to and after product use. A community-based sample recruited in the Midwest region of the United States reported a mean age of 28.6 [standard deviation (SD) = 12.9]. The majority were male (56.5%), Caucasian (91.3%), reported smoking an average of 15.2 (SD = 9.6) tobacco cigarettes per day, and a mean baseline carbon monoxide (CO) level of 18.7 parts per million (p.p.m.). Symptoms of withdrawal from nicotine were measured via the Mood and Physical Symptoms Scale. Analysis of changes in withdrawal symptoms revealed a significant time × product interaction F(1, 21)  = 5.057, P = 0.036, n(2) P  = 0.202. Participants experienced a larger reduction in symptoms of nicotine withdrawal after using second-generation compared with first-generation e-cigarettes. Second-generation e-cigarettes seem to be more effective in reducing symptoms of nicotine withdrawal than do first-generation e-cigarettes. © 2015 Society for the Study of Addiction.

To investigate the comparative efficacy of bevacizumab (Avastin) and ranibizumab (Lucentis; both Genentech, Inc, South San Francisco, CA) for diabetic macular edema (DME) using a crossover study design. Randomized, double-masked, 36-week, 3-period crossover clinical trial. Fifty-six subjects with DME involving the center of the macula in one or both eyes. Monthly intravitreous injections of bevacizumab (1.25 mg) or ranibizumab (0.3 mg). Comparison of mean changes in visual acuity and central retinal thickness, tested using a linear mixed-effects model. Based on the linear mixed-effects model, the 3-month estimated mean improvement in visual acuity was 5.3 letters for bevacizumab and 6.6 letters for ranibizumab (difference, 1.3 letters; P = 0.039). Estimated change in optical coherence tomography (OCT) central subfield mean thickness (CSMT) was -89 μm for bevacizumab and -137 μm for ranibizumab (difference, 48 μm; P < 0.001). Incorporating cumulative treatment benefit, the model yielded a predicted 36-week (9-month) average improvement in visual acuity of 7.1 letters (95% confidence interval [CI], 5.0-9.2) for bevacizumab and 8.4 letters (95% CI, 6.3-10.5) for ranibizumab, and a change in OCT CSMT of -128 μm (95% CI, -155 to -100) for bevacizumab and -176 μm (95% CI, -202 to -149) for ranibizumab. There was no significant treatment-by-period interaction (i.e., treatment difference was constant in all 3 periods), nor was there a significant differential carryover effect from one period to the next. This trial demonstrated a statistically significant but small relative clinical benefit of ranibizumab compared with bevacizumab for treatment of DME, using a markedly reduced sample size relative to a full comparative efficacy study. The effects on visual acuity and central retinal thickness for the 2 drugs are consistent with those reported at 1 year for the concurrent parallel-group trial by the Diabetic Retinopathy Clinical Research Network testing bevacizumab

Overweight and obesity are a massive public health problem and young adults are at high risk for gaining weight once they enter a college. This study sought to examine gender and race as they relate to nutrition habits and self-efficacy in a population of diverse young adults from the Young Adult Weight Loss Study. Participants ( N = 62) were 29% males, 38.7% white, 33.8% Asian, and 12.9% African American. Males had lower self-efficacy for healthy eating (mean score = 92.5, SD = 17.1) compared to females (mean = 102.3, SD = 13.7, p = 0.02). Males had higher consumption of sodium compared to females (4308 versus 3239 milligrams/day, p = 0.01). There were no significant differences across racial subgroups in self-efficacy for healthy eating ( p = 0.67) or self-efficacy for exercise ( p = 0.61). Higher self-efficacy scores for healthy eating were significantly associated with less total sodium ( r = -0.37, p = 0.007), greater fruit consumption, and less saturated fat. Our results indicate that weight loss interventions should be individualized and that there may be specific areas to target that are different for men and women. Additional larger studies should be conducted to confirm if racial differences exist across nutrition habits and self-efficacy and to confirm gender differences noted in this study.

Full Text Available Overweight and obesity are a massive public health problem and young adults are at high risk for gaining weight once they enter a college. This study sought to examine gender and race as they relate to nutrition habits and self-efficacy in a population of diverse young adults from the Young Adult Weight Loss Study. Participants (N=62 were 29% males, 38.7% white, 33.8% Asian, and 12.9% African American. Males had lower self-efficacy for healthy eating (mean score = 92.5, SD = 17.1 compared to females (mean = 102.3, SD = 13.7, p=0.02. Males had higher consumption of sodium compared to females (4308 versus 3239 milligrams/day, p=0.01. There were no significant differences across racial subgroups in self-efficacy for healthy eating (p=0.67 or self-efficacy for exercise (p=0.61.

To evaluate the efficacy of do-it-yourself (DIY) whitening as compared to conventional tooth whitening modalities using different shade assessment tools. Extracted human molars (120) were randomly distributed to six groups (n=20). Whitening was performed according to manufacturer's directions for over-the-counter, dentist-dispensed for home use, and in-office whitening. DIY whitening consisted of a strawberry and baking soda mix. Additionally, negative and positive controls were used. Two evaluators used the Vita Classical (VC) and Vita Bleachedguide 3D-Master with interpolated numbers (BGi) for visual assessment at baseline and one-week, one-month, and three-month postwhitening. Instrumental measurements were performed with a spectrophotometer. Kruskal-Wallis procedure was used to assess color changes among groups and intraclass correlation (ICC) to evaluate agreement between evaluators. DIY exhibited lower color change (ΔSGUVC, ΔSGUBGi, ΔE*, where SGU = shade guide unit and E = overall color change) compared to other whitening groups at all time points (p<0.05). ICC demonstrated very good agreement between evaluators with VC and BGi at each time point. Both shade guides were related with each other and strongly related to instrumental measurements (p<0.05). DIY whitening was the least effective whitening modality. Both VC and BGi are related with each other and have good correlation with instrumental measurements.

2001-01-01

The aim of this study was to investigate the efficacy of nootropics (piracetam, aniracetam, nimodopine and dihydroergicristine) versus acetylcholinesterase inhibitors (AChE-Is) (tacrine and donepezil) in the treatment of Alzheimer's disease. This is a retrospective study of 510 patients with Alzheimer's disease. To determine clinical efficacy of treatment, we used the mean change over time in scores for the following tests: the Mini-Mental State Examination (MMSE); the Cambridge Cognitive Examination for the Elderly; and the Functional Rating Scale for Symptoms of Dementia. In all patients and in patients with severe Alzheimer's disease (baseline MMSE nootropics (-4.38 for AChE-Is group versus 1.48 for nootropics group). For patients with mild dementia (baseline MMSE score between 21 and 26), there was a significantly greater deterioration on the MMSE scale for each time-point in the nootropics group compared with the AChE-Is group. In conclusion, we did not find any strong evidence that a difference in efficacy exists between AChE-Is and nootropics in the treatment of Alzheimer's disease.

To investigate the efficacy and safety of switching from infliximab reference product (RP) to its biosimilar or maintaining biosimilar treatment in patients with ankylosing spondylitis (AS). This open-label extension study recruited patients with AS who completed a 54-week, randomised controlled study comparing CT-P13 with RP (PLANETAS). CT-P13 (5 mg/kg) was administered intravenously every 8 weeks from week 62 to week 102. Efficacy end points included the proportion of patients achieving Assessment of SpondyloArthritis international Society (ASAS)20. Antidrug antibodies (ADAs) were measured using an electrochemiluminescent method. Data were analysed for patients treated with CT-P13 in the main PLANETAS study and the extension (maintenance group) and those who were switched to CT-P13 during the extension study (switch group). Overall, 174 (82.9%) of 210 patients who completed the first 54 weeks of PLANETAS and agreed to participate in the extension were enrolled. Among these, 88 were maintained on CT-P13 and 86 were switched to CT-P13 from RP. In these maintenance and switch groups, respectively, ASAS20 response rates at week 102 were 80.7% and 76.9%. ASAS40 and ASAS partial remission were also similar between groups. ADA positivity rates were comparable (week 102: 23.3% vs 27.4%). Adverse events led to treatment discontinuation during the extension study in 3 (3.3%) and 4 (4.8%) patients, respectively. This is the first study to show that switching from RP to its biosimilar CT-P13 is possible without negative effects on safety or efficacy in patients with AS. In the maintenance group, CT-P13 was effective and well tolerated over 2 years of treatment. NCT01571206; Results. Published by the BMJ Publishing Group Limited.

Full Text Available The acaricidal efficacy of afoxolaner (NexGard®, Merial was evaluated against Sarcoptes scabiei var. canis in a field efficacy study, when administered orally at a minimum dose of 2.5 mg/kg to dogs naturally infested with the mites. Twenty mixed-breed dogs of either sex (6 males and 14 females, aged over 6 months and weighing 4–18 kg, were studied in this randomised controlled field efficacy trial. Dogs, naturally infested with Sarcoptes scabiei var. canis confirmed by skin scrapings collected prior to allocation, were randomly divided into two equal groups. Dogs in Group 1 were not treated. Dogs in Group 2 were treated on Days 0 and 28. On Days 0 (pre-treatment, 28 (pre-treatment and 56, five skin scrapings of similar size were taken from different sites with lesions suggestive of sarcoptic mange. The extent of lesions was also recorded on Days 0, 28 and 56, and photographs were taken. Dogs treated orally with afoxolaner had significantly (p < 0.001 lower mite counts than untreated control animals at Days 28 and 56 with no mites recovered from treated dogs at these times (100% efficacy based on mite counts. In addition, dogs treated with NexGard had significantly (p < 0.05 better lesion resolution at Day 56 than Day 0; no treated dog showed pruritus compared to 7/10 dogs in the control group, 1/9 treated dogs had crusts compared to 5/10 controls and 8/9 dogs recovered 90% of hairs on lesions compared to 0/10 control dogs.

Full Text Available Background: The success of labor induction is extremely dependent on the state of the cervix. There are various methods available in modern obstetrics practice for ripening the cervix, such as intravaginal prostaglandins and mechanical devices like transcervical catheters. Although plenty of studies have already compared the two methods for the unripened cervices, more studies are warranted in nulliparous patients only. This study aimed to compare the efficacy of intravaginal misoprostol tablets with transcervical Foley catheter for cervical ripening in nulliparous patients. Methods & Materials: In this randomized clinical trial, 120 nulliparous candidates for labor induction were recruited from two teaching centers in Tabriz within a 17-month period of time. All the enrolled cases had a live singleton fetus with cephalic presentation at term (≥37 weeks, on-admission Bishop Score≤4, intact membranes and reactive non-stress test results. They were randomly assigned to two equal age-matched groups receiving either intravaginal misoprostol (25 microgram, n=59, or transcervical insertion of 16F Foley catheter (n=60. Results: One time successful induction (i.e. successful induction after a single insertion of misoprostol, or expulsion of transcervical Foley catheter within 12 h of insertion was achieved in all the patients without employment of other methods such as use of syntocinon. Misoprostol was more effective in terms of induction-to-cervical ripening interval (15.16±3.59 h vs. 18.30±1.59 h; p<0.001. Tachysystole, on the other hand, was significantly more frequent in the misoprostol receivers (25.4% vs. 0%; p<0.001. The two groups were comparable for the rate of cesarean section (misoprostol, 37.3%; Folly catheter, 30%; p=0.40. Comparing the two groups, there was no significant difference with regard to change in Bishop Score (misoprostol, 1.90±0.54 h-1; Folly catheter, 1.89±0.74 h-1; p=0.95 and miscellaneous pregnancy-related and fetal

ELA-Max and EMLA cream are topical anesthetics that have been shown to have similar anesthetic efficacy in previous studies. To evaluate the analgesic efficacy of ELA-Max in comparison with EMLA cream using a novel method of thermosensory threshold analysis. A thermosensory analyzer was used to assess warmth- and heat-induced pain thresholds. No statistically significant difference was found in pain thresholds using either formulation. However, EMLA cream increased the heat-induced pain threshold to a greater extent than ELA-Max. Thermosensory measurement and analysis was well tolerated and no adverse events were encountered. EMLA cream may be superior to ELA-Max for heat-induced pain. This study suggests that thermosensory measurement may be another suitable tool for future topical anesthetic efficacy studies.

To compare the efficacy of a transdermal buprenorphine patch (5, 10, 15, and 20 μg/h) with that of oral tramadol (150, 200, 250, and 300 mg) for postoperative pain control after single level spinal fusion surgery. The present study (ClinicalTrials.gov, number NCT02416804) was a prospective, randomized controlled non-inferiority trial designed to determine the efficacy of buprenorphine TDS for alleviating postoperative pain following patient controlled analgesia (PCA) in persons underwent a single level posterior lumbar interbody fusion surgery through 1:1 allocation. The primary outcome was the Visual Analog Pain Scale (VAS) score for postoperative back pain at 7 days after surgery. The non-inferior margin of the VAS was set at δ = 1.5 points. The VAS score (primary outcome) for postoperative back pain at 7 days after surgery in the Buprenorphine group was not inferior compared to the Tramadol group. The overall changes in VAS scores for postoperative pain during follow-up assessments over a 2-week period did not differ between both groups. However, the VAS scores for postoperative pain significantly improved with time after surgery in both groups. The patterns of changes in the VAS scores for postoperative pain during the follow-up period were not significantly different between the both groups. The efficacy of buprenorphine TDS was not inferior to that of oral tramadol medication for alleviating postoperative pain in the subacute period from 72 h after surgery, following PCA administration. In addition, adverse events were similar between both groups.

Full Text Available Objective. To compare the efficacy of low-dose COC containing desogestrel (DSG with drospirenone (DRSP in the changes of premenstrual symptoms. Methods. In an open-label randomized controlled trial, 90 women with premenstrual syndrome who required COC were randomly recruited and allocated equally to receive either 6 cycles of 20 micrograms ethinyl estradiol (EE/150 micrograms DSG (DSG group or 20 micrograms EE/3 mg DRSP (DRSP group in 24/4 extended regimen. Analysis of covariance and repeated analysis of variance were used to determine the difference of mean Women's Health Assessment Questionnaire (WHAQ scores changes between groups, within group, and in premenstrual, menstrual, and postmenstrual phases. Results. Baseline characteristics and WHAQ scores were comparable. At the ends of the 3rd and the 6th cycles, mean WHAQ scores of all the 3 phases in DRSP group showed significant reduction and were significantly lower than those in DSG group. DSG group showed significant reduction in both premenstrual and menstrual phases after the 6th cycle. Adverse effects were comparable in both groups. In conclusion, low-dose COC containing either DSG or DRSP reduced premenstrual symptoms, but the latter showed greater efficacy and earlier reduction.

Full Text Available Aim: In the present study, a therapeutic trial was conducted to assess comparative efficacy of crystalloid plus colloid and crystalloid intravenous infusions alone as fluid therapy in dogs suffering from hemorrhagic gastroenteritis (HGE. Materials and Methods: 20 dogs manifesting HGE, presented at Teaching Veterinary Clinical Services Complex, Ludhiana, Punjab, were selected randomly for the trial. All of them were observed to suffer from moderate dehydration on clinical examination. Crystalloids 5% DNS and RL were used in combination with polygelin 3.5% colloidal solution in the first group (Combination I and in the second group, the afore-said crystalloids (Combination II were used, both groups consisting of 10 cases each. Antibiotics and symptomatic treatment were same for all the 20 cases. The outcome of both treatment groups was evaluated on hemato-biochemical parameters, before and after administration of the therapies and compared statistically within and between the two groups. Hemato-biochemical parameters of eight clinically healthy animals were considered as control for comparison. Result: On hemato-biochemical examination, significant alterations were observed in leucogram, platelet and serum globulin concentration after the treatment in the first group as compared to before treatment values. In the second group, mean hemoglobin varied significantly after the treatment. After therapies were administered, significant difference in serum globulin level and albumin: Globulin was found in between the treatment groups (Combination I and Combination II. Clinical recovery was faster in the first group than the second group of animals. Conclusion: On hemodynamic and laboratory data, efficacies of both the fluid therapies were equivocal. Colloidal solutions may hasten recovery in small animals suffering from gastrointestinal crisis.

The early infant-mother attachment relationship is part of a network of close relationships in which the relationship between parents is especially relevant. Evidence for linkages between maternal satisfaction with the partner relationship and infant-mother attachment is equivocal. The current study tested whether associations between partner relationship dissatisfaction and infant-mother attachment quality might be conditional on mothers' parenting self-efficacy. The bivariate effect of partner relationship dissatisfaction on infant-mother attachment as well as moderation of this effect by parenting self-efficacy was tested in a sample of 260 infant-mother dyads 1 year after birth. There was no direct effect of partner dissatisfaction on attachment. Unexpectedly, for high parenting self-efficacy, greater partner dissatisfaction increased the odds of an avoidant infant attachment (compared with a disorganized) whereas, for low parenting self-efficacy, greater partner dissatisfaction decreased the odds of an avoidant infant attachment (compared with secure and disorganized). Findings underline the importance of parenting cognitions for understanding contextual factors of infant-mother attachment quality. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Few treatment modalities are available for treating alopecia areata (AA) of the eyebrow. Due to the anatomical proximity of the eyebrows to the eyes, safety issues and side effects should always be taken into consideration when choosing the treatment modality. This study was designed to examine the efficacy of superficial cryotherapy on patients with AA of the eyebrow. Superficial cryotherapy was performed every other week on the right eyebrow (SC-treated) in a total of 20 patients who had been previously treated with diphenylcyclopropenone (DPCP) immunotherapy on the scalp. No specific treatment was performed on the left eyebrows as a control. The degree of eyebrow recovery was compared in 15 patients who continued to receive more than 10 superficial cryotherapy treatments (5 months of treatment) on their right eyebrow. Hair density was significantly increased on both treated and control eyebrows after 5 months of treatment compared with the pretreatment density; moreover, the SC-treated eyebrows exhibited a significantly greater increase in density than the control eyebrows. Although hair thickness in the control eyebrows did not change significantly over the treatment period, hair thickness of the SC-treated eyebrows showed a statistically significant increase at months 3 and 5. Superficial cryotherapy is associated with minimal to no adverse events and exhibits high compliance and relatively good efficacy. Thus, this treatment is an important additional option for patients with AA of the eyebrow. © 2017 The International Society of Dermatology.

Topical minoxidil and oral finasteride have been used to treat men with androgenetic alopecia (AGA). There are concerns about side effects of oral finasteride especially erectile dysfunction. To compare the efficacy and safety of the 24 weeks application of 3% minoxidil lotion (MNX) versus combined 3% minoxidil and 0.1% finasteride lotion (MFX) in men with AGA. Forty men with AGA were randomized treated with MNX or MFX. Efficacy was evaluated by hair counts and global photographic assessment. Safety assessment was performed by history and physical examination. At week 24, hair counts were increased from baseline in both groups. However paired t-test revealed statistical difference only in MFX group (p = 0.044). Unpaired t-test revealed no statistical difference between two groups with respect to change of hair counts at 24 weeks from baseline (p = 0.503). MFX showed significantly higher efficacy than MNX by global photographic assessment (p = 0.003). There was no significant difference in side effects between both groups. Although change of hair counts was not statistically different between two groups, global photographic assessment showed significantly greater improvement in the MFX group than the MNX group. There was no sexual side effect. MFX may be a safe and effective treatment option.

The purpose of this study was to compare two different groups of drugs, aprotinin and dexamethasone for its efficacy in reducing post operative swelling and pain after third molar surgery. Fifty consecutive patients requiring surgical removal of single mandibular third molar (class II position B) under local anesthesia were randomly divided into two groups, each group consisting of 25 patients. One group was administered 8 mg dexamethasone through intravenous route pre-operatively. The other group received 1 ml of Aprotinin through submucosal route in operating area after the onset of local anesthesia. Swelling was assessed by measuring facial contours at baseline and at 1st, 3rd and 7th post-operative days. Pain was measured on the 1st, 3rd and 7th post-operative days using visual analog scale. Based on statistical analysis (paired t test and Wilcoxon's signed ranking test), the results showed statistically significant difference in post operative swelling and pain on 3rd postoperative day in dexamethasone group as compared to aprotinin group. The results of present study showed a similar reduction in the severity of pain and swelling at the aprotinin and dexamethasone sites on 1st and 7th postoperative day. It was also noticed that the aprotinin promoted a greater reduction of swelling and pain on 3rd postoperative day. It appeared that, benefits of aprotinin against the risks of dexamethasone and its efficacy in controlling pain and swelling after third molar surgery makes aprotinin to be a valuable alternative to dexamethasone.

2010-01-01

Effective handwashing with soap requires reliable access to water supplies. However, more than three billion persons do not have household-level access to piped water. This research addresses the challenge of improving hand hygiene within water-constrained environments. The antimicrobial efficacy of alcohol-based hand sanitizer, a waterless hand hygiene product, was evaluated and compared with handwashing with soap and water in field conditions in Dar es Salaam, Tanzania. Hand sanitizer use by mothers resulted in 0.66 and 0.64 log reductions per hand of Escherichia coli and fecal streptococci, respectively. In comparison, handwashing with soap resulted in 0.50 and 0.25 log reductions per hand of E. coli and fecal streptococci, respectively. Hand sanitizer was significantly better than handwashing with respect to reduction in levels of fecal streptococci (P = 0.01). The feasibility and health impacts of promoting hand sanitizer as an alternative hand hygiene option for water-constrained environments should be assessed. PMID:20134005

To comparatively evaluate the antimicrobial efficacy of freshly prepared electrolyzed oxidizing water (EOW) with that of 2.4% glutaraldehyde (GA) and 1% sodium hypochlorite (SH) on clinically derived poly vinyl siloxane (PVS) impressions. Four clinically derived PVS impressions each were obtained from 10 subjects. One impression from each subject was randomly kept as control (group I), without disinfection. The remaining three impressions were randomly disinfected by immersion in either 2.4% GA (group II), 1% SH (group III), or freshly prepared EOW (group IV). The samples were subjected to microbial culture individually on brain heart infusion (BHI) agar medium. The organisms isolated were confirmed by visual examination and gram staining. Mean colony forming units (CFU) were counted, log 10 reduction obtained and compared. Data were statistically analyzed using one-way ANOVA, followed by multiple comparisons using Tukey-HSD post hoc tests (p < 0.05). Streptococci, Staphylococci, Pseudomonas, Candida, Proteus, Klebsiella, and E. coli were isolated from all impressions including the controls, except those disinfected by EOW. All three disinfectants showed significant reduction in CFU and log 10 reduction values as compared to the controls. EOW showed significantly higher reduction in log 10 values compared to GA and SH, whereas GA and SH showed similar reductions. EOW, GA, and SH showed kill rates of 100%, 99.60%, and 99.82%, respectively. EOW showed significant antimicrobial efficacy as evidenced by reduction in log 10 values when used as an immersion disinfectant for PVS impressions when compared with the results obtained using GA and SH. These results need further investigation. EOW shows high antimicrobial efficacy when used as an immersion disinfectant as compared to GA and SH for clinically derived PVS impressions. © 2016 by the American College of Prosthodontists.

Full Text Available Introduction: Peroral endoscopic myotomy (POEM has been performed since 2008 on more than 5,000 patients. It has proven to be highly effective in the treatment of achalasia and has shown promising outcomes for other esophageal motility spastic disorders. Methods: A literature review of the efficacy of POEM compared to the previous invasive treatments for different esophageal motility disorders was performed. The application in the pediatric and elderly populations and its role as a rescue therapy after other procedures are also outlined. Results: Short-term outcomes are similar to laparoscopic Heller myotomy (LHM and pneumatic endoscopic dilation (PD (clinical success > 90% for achalasia subtypes I and II. Mid-term outcomes are comparable to LHM and overcome results obtained after PD (> 90% vs ~50%. With regard to type III achalasia, POEM efficacy is 98% compared to 80.8% for LHM and the PD success remains at 40%. With regard to spastic esophageal disorders (SED, POEM has an effectiveness of 88% and 70% for distal esophageal spasm (DES and jackhammer esophagus (JE respectively. A response of 95% in patients with sigmoid esophagus has been reported. POEM has been performed in pediatric and elderly populations and has obtained a higher efficacy than PD in pediatric series (100% vs 33% without greater adverse events. Previous treatments do not seem to hinder POEM results with excellent response rates, including 97% in post LHM and 100% in a re-POEM series. Final considerations: POEM has shown excellent short and mid-term results for all subtypes of achalasia but long-term results are not yet available. The promising results in SED may make POEM the first-line treatment for SED. A high-safety profile and efficacy have been shown in elderly and pediatric populations. Previous treatments do not seem to diminish the success rate of POEM. Core tip: POEM has emerged as an efficient treatment option for all subtypes of achalasia and other scenarios

Short-term outcomes are similar to laparoscopic Heller myotomy (LHM) and pneumatic endoscopic dilation (PD) (clinical success > 90%) for achalasia subtypes I and II. Mid-term outcomes are comparable to LHM and overcome the results obtained after PD (> 90% vs ~50%). With regard to type III achalasia, POEM efficacy is 98% compared to 80.8% for LHM and the PD success remains at 40%. With regard to spastic esophageal disorders (SED), POEM has an effectiveness of 88% and 70% for distal esophageal spasm (DES) and jackhammer esophagus (JE) respectively. A response of 95% in patients with sigmoid esophagus has been reported. POEM has been performed in pediatric and elderly populations and has obtained a higher efficacy than PD in pediatric series (100% vs 33%) without greater adverse events. Previous treatments do not seem to hinder POEM results with excellent response rates, including 97% in post LHM and 100% in a re-POEM series. Final considerations: POEM has shown excellent short and mid-term results for all subtypes of achalasia but long-term results are not yet available. The promising results in SED may make POEM the first-line treatment for SED. A high-safety profile and efficacy have been shown in elderly and pediatric populations. Previous treatments do not seem to diminish the success rate of POEM. Core tip: POEM has emerged as an efficient treatment option for all subtypes of achalasia and other scenarios (including previous treatments and elderly

To investigate contraceptive efficacy, compliance and user's satisfaction with transdermal versus oral contraception (OC). Randomized, open-label, parallel-group trial conducted at 65 centers in Europe and South Africa. One thousand four hundred and eighty-nine women received a contraceptive patch (n = 846) or an OC (n = 643) for 6 or 13 cycles. Overall/method-failure Pearl Indices were 0.88/0.66 with the patch and 0.56/0.28 with the OC (p = n.s.). Compliance was higher at all age groups with the patch compared to the OC. Significantly more users were very satisfied with the contraceptive patch than with the OC. The percentage of patch users being very satisfied increased with age whereas it did not in the OC group. Likewise, improvements of premenstrual symptoms as well as emotional and physical well-being increased with age in the patch-group in contrast to the OC group. Ratings of satisfaction with the study medication correlated weakly with emotional (r = 0.33) and physical well-being (r = 0.39) as well as premenstrual symptoms (r = 0.30; p Contraceptive efficacy of the patch is comparable to OC, but compliance is consistently better at all age groups. Higher satisfaction with the patch at increasing age may be attributed to improvements in emotional and physical well-being as well as reduction of premenstrual symptoms.

Full Text Available Abstract Background The reduction of malaria parasite transmission by preventing human-vector contact is critical in lowering disease transmission and its outcomes. This underscores the need for effective and long lasting arthropod/insect repellents. Despite the reduction in malaria transmission and outcomes in Tanzania, personal protection against mosquito bites is still not well investigated. This study sought to determine the efficacy of menthol propylene glycol carbonate (MR08, Ocimum suave as compared to the gold standard repellent N, N-diethyl-methylbenzamide (DEET, either as a single dose or in combination (blend, both in the laboratory and in the field against Anopheles gambiae s.l and Culex quinquefasciatus. Methods In the laboratory evaluations, repellents were applied on one arm while the other arm of the same individual was treated with a base cream. Each arm was separately exposed in cages with unfed female mosquitoes. Repellents were evaluated either as a single dose or as a blend. Efficacy of each repellent was determined by the number of mosquitoes that landed and fed on treated arms as compared to the control or among them. In the field, evaluations were performed by human landing catches at hourly intervals from 18:00 hr to 01:00 hr. Results A total of 2,442 mosquitoes were collected during field evaluations, of which 2,376 (97.30% were An. gambiae s.l while 66 (2.70% were Cx. quinquefaciatus. MR08 and DEET had comparatively similar protective efficacy ranging from 92% to 100 for both single compound and blends. These findings indicate that MR08 has a similar protective efficacy as DEET for personal protection outside bed nets when used singly and in blends. Because of the personal protection provided by MR08, DEET and blends as topical applicants in laboratory and field situations, these findings suggest that, these repellents could be used efficiently in the community to complement existing tools. Overall, Cx

Full Text Available Abstract Background Previous studies have demonstrated that adverse events occur during chiropractic treatment. However, because of these studies design we do not know the frequency and extent of these events when compared to sham treatment. The principal aims of this study are to establish the frequency and severity of adverse effects from short term usual chiropractic treatment of the spine when compared to a sham treatment group. The secondary aim of this study is to establish the efficacy of usual short term chiropractic care for spinal pain when compared to a sham intervention. Methods One hundred and eighty participants will be randomly allocated to either usual chiropractic care or a sham intervention group. To be considered for inclusion the participants must have experienced non-specific spinal pain for at least one week. The study will be conducted at the clinics of registered chiropractors in Western Australia. Participants in each group will receive two treatments at intervals no less than one week. For the usual chiropractic care group, the selection of therapeutic techniques will be left to the chiropractors' discretion. For the sham intervention group, de-tuned ultrasound and de-tuned activator treatment will be applied by the chiropractors to the regions where spinal pain is experienced. Adverse events will be assessed two days after each appointment using a questionnaire developed for this study. The efficacy of short term chiropractic care for spinal pain will be examined at two week follow-up by assessing pain, physical function, minimum acceptable outcome, and satisfaction with care, with the use of the following outcome measures: Numerical Rating Scale, Functional Rating Index, Neck Disability Index, Minimum Acceptable Outcome Questionnaire, Oswestry Disability Index, and a global measure of treatment satisfaction. The statistician, outcome assessor, and participants will be blinded to treatment allocation. Trial

Toward making the invisible visible: Studying science teaching self-efficacy beliefs

Science.gov (United States)

Perkins, Catherine J.

This dissertation consists of two articles to be submitted for publication. The first, a literature review, makes visible common influences on science teaching self-efficacy beliefs and also points to potentially invisible validation concerns regarding the instrument used. The second investigates the participants' invisible science teaching self-efficacy beliefs and, through the use of a more focused interview, makes those beliefs visible. Science teaching self-efficacy beliefs are science teachers' perceptions of their abilities to teach science effectively. The construct "teaching self-efficacy" originated in social cognitive theory (Bandura, 1977). The first article reviews the mixed results from teaching self-efficacy research in science contexts. The review focuses upon factors that facilitate or inhibit the development of self-efficacy beliefs among science teachers across stages of their careers. Although many studies of science teaching self-efficacy beliefs have utilized the Science Teaching Efficacy Belief Instrument - STEBI (Enochs & Riggs, 1990; Riggs & Enochs, 1990), this review also includes non-STEBI studies in order to represent diverse lines of research methodology. The review's findings indicate that antecedent factors such as science activities in and out of school, teacher preparation, science teaching experiences and supportive job contexts are significant influences on the development of science teaching self-efficacy beliefs. The review also indicates that the majority of these studies are short term and rely on a single STEBI administration with the collection of antecedent/demographic and/or interview data. The second article documents a study that responded to the above literature review findings. This study utilized multiple STEBI administrations during the preservice and beginning year of teaching for two science teachers. Rather than general questions, these participants were asked item specific, yet open-ended, questions to determine

Comparative efficacy of five commonly used insecticides viz., acetamiprid, buprofezin, diafenthiuron, imidacloprid and endosulfan against nymph and adult population of cotton whitefly, Bemisia tabaci (Gennadius) (Homoptera: Aleyrodidae) under natural field conditions has been studied. Results showed that buprofezin was the most effective insecticide against nymph population of whitefly among the tested insecticides where nymphal population of B. tabaci was 0.2/leaf after 24h spray as compared to 1.9/leaf in control. Acetamiprid was the most effective against adult population of whitefly (0.3 to 1.3/leaf post 72 h spray, as compared to control with 6.9 to 8.2/leaf) followed by diafenthiuron and imidaclopirid. whereas, endosulfan was found to be the least effective on both populations as adult and nymph of whitefly. From the tested insecticides, acetamaprid gave effective control of both nymph and adult population of B. tabaci. (author)

Aims Multimodal analgesia is thought to produce balanced and effective postoperative pain control. A combined therapy with nonsteroidal anti-inflammatory drugs (NSAIDs) and opiates could result in synergistic analgesia by acting through different mechanisms. Currently there are very few parenterally administered NSAIDs suitable for the immediate postoperative period. Therefore, this study was undertaken to assess the analgesic efficacy, relative potency, and safety of parenteral dexketoprofen trometamol following major orthopaedic surgery. Methods One hundred and seventy-two patients elected for prosthetic surgery, were randomized to receive two intramuscular injections (12 hourly) of either dexketoprofen 50 mg, ketoprofen 100 mg or placebo in a double-blind fashion. Postoperatively, the patient's pain was stabilized, then they were connected to a patient- controlled analgesia system (PCA) of morphine for 24 h (1 mg with 5 min lockout). Results The mean cumulative amount of morphine (CAM) used was of 39 mg in the dexketoprofen group and 45 mg in the ketoprofen group vs 64 mg in the placebo group. (Reduction in morphine use was approximately one-third between the active compounds compared with placebo (adjusted mean difference of −25 mg between dexketoprofen and placebo and −23 mg between ketoprofen and placebo. These differences were statistically significant: P ≤ 0.0003; 95% CI −35, −14. Pain-intensity scores were consistently lower with the active compounds, the lowest corresponded to the dexketoprofen-treated patients. Regarding sedation, there were statistically significant differences between the two active compounds and placebo only at the 2nd and 13th hours. Wound bleeding was specifically measured with no statistically significant differences found between all the groups. Conclusions Intramuscular administration of dexketoprofen trometamol 50 mg has good analgesic efficacy both in terms of opioid-sparing effect and control of pain after major

Full Text Available Self-efficacy is a strong predictor of academic performance, and an area of interest for higher education institutions. This paper reports on a massive open online course (MOOC on study skills, aimed at increasing self-efficacy. Participants (n=32 were from Mexico and Colombia, with ages ranging from 21 to 45 years. At the beginning and the end of the MOOC, learners answered a survey that included the General Self-Efficacy Scale, items on specific study skills, and space for optional comments. Findings show statistically significant increases in general self-efficacy after completing the MOOC, as well as in the perceived self-efficacy related to five out of six study skills. Comments suggest that participants are aware of and value their own improvement. For students, MOOCs can represent low-risk, formative opportunities to widen their knowledge and increase their self-efficacy. For academic institutions, well-designed MOOCs on study skills provide a means to support students.

Full Text Available BACKGROUND Extracorporeal shock wave lithotripsy (ESWL is well known for its non-invasiveness, effectiveness and minimal morbidity for the management of renal stones. Some generation of lithotripters were associated with significant pain, needing anaesthesia. In modern lithotripters, pain is insignificant making lithotripsy an outpatient procedure (day care. AIMS The present study is aimed to compare the clinical efficacy between four drugs. METHODS AND MATERIALS This was a prospective study of 1000 patients with normal BMI (25-30 who underwent ESWL in the Year 2012-15 at our institute. All the patients with renal stones were randomly divided into 4 groups. Dornier Compact Sigma lithotripsy machine was used in all the patients. Group A was given IM diclofenac sodium (1 mg/kg, 60 minutes before the procedure. In group B, 10 g of EMLA cream; and in group C, 15 g of diclofenac diethylamine gel; in group D placebo (electrode gel was applied locally. STATISTICAL ANALYSIS Visual analogue scale (VAS was used to assess the severity of pain for initial 5-10 minutes and after the procedure. A P value of less than 0.05 was considered to be statistically significant. Statistical analysis was done using one way ANOVA and results were compared between four groups. RESULTS All four groups were having comparable age, weight, stone size, number of shock waves delivered and maximum voltage used. In group A total 250 patients (M/F: 177/73, group B 250 patients (M/F: 129/121, group C 250 patients (M/F: 158/92, group D 250 patients (M/F: 162/88. With regard to pain scores, the responses were better in group B. According to location of the stones, majority of the stones were located in pelvis (41.5%, followed by upper (30.5% and middle calyx (16.8% and least in the lower calyx (11.2%. Overall stone free rate in our study was 75.5%, with least clearance in lower calyceal stones. 112 patients were stented prior to the procedure. Ureteroscopy and RIRS (Retrograde

The efficacy of primary care chaplaincy compared with antidepressants: a retrospective study comparing chaplaincy with antidepressants.

Aim To determine the effectiveness of primary care chaplaincy (PCC) when used as the sole intervention, with outcomes being compared directly with those of antidepressants. This was to be carried out in a homogenous study population reflective of certain demographics in the United Kingdom. Increasing numbers of patients are living with long-term conditions and 'modern maladies' and are experiencing loss of well-being and depression. There is an increasing move to utilise non-pharmacological interventions such as 'talking therapies' within this context. Chaplaincy is one such 'talking therapy' but within primary care its evidence base is sparse with only one quantitative study to date. There is therefore a need to evaluate PCC excluding those co-prescribed antidepressants, as this is not evidenced in the literature as yet. PCC also needs to be directly compared with the use of antidepressants to justify its use as a valid alternative treatment for loss of well-being and depression. This was a retrospective observational study based on routinely collected data. There were 107 patients in the PCC group and 106 in the antidepressant group. Socio-demographic data were collected. Their pre- and post-intervention (either chaplaincy or antidepressant) well-being was assessed, by the Warwick-Edinburgh Mental Well-being Scale (WEMWBS) which is a validated Likert scale. Findings The majority of both groups were female with both groups showing marked ethnic homogeneity. PCC was associated with a significant and clinically meaningful improvement in well-being at a mean follow-up of 80 days. This treatment effect was maintained after those co-prescribed antidepressants were removed. PCC was associated with an improvement in well-being similar to that of antidepressants with no significant difference between the two groups.

Praziquantel (PZQ) is the current drug of choice for the treatment of urinary schistosomiasis in endemic areas. It is very efficacious, although the potential for the development of resistance has been reported in some endemic areas among human subjects and in animal studies. Its' limitation include high cost and administration of multiple numbers of tablets. Albendazole (ALB) is used in the treatment of intestinal helminths infection. It is a broad-spectrum single-dose antihelminthic with an excellent cure rate and safety criteria. Currently, it is not routinely used for the treatment of urinary schistosomiasis. Urine samples collected from 596 pupils aged between 2 and 16 years were processed and examined for the presence of ova of Schistosoma haematobium using a standard filtration technique. A total of 100 infected subjects were treated with a standard dose of PZQ (40 mg/kg body weight), while another group of 96 infected subjects were treated with ALB (400 mg for individuals above 3 years). A post-treatment study was conducted 1 month after treatment to assess their cure rate. The prevalence of S. haematobium infection in the study area was 32.8% (196/596). More males were infected (44.2%) (122/276) than females (23.1%) (74/320). The difference in the prevalence rate of infection by gender was statistically significant (X2=15.7>3.841, p0.05). PZQ gave a higher cure rate of 78.0% (78/100) compared with ALB (68.7%) (66/96). There was no statistically significant difference in the cure rate obtained with both drugs (X2=0.355>0.282, p>0.05). The intensity of egg excretion was greatly reduced in subjects who were not cured by the two drugs. The findings of this study suggest the use of ALB for the treatment of urinary schistosomiasis. We recommend further assessment of the efficacy of the drug in an area with higher morbidity of urinary schistosomiasis than the present study area. © The Author 2017.

This study aimed to compare the effect of e-learning and educational booklet on the childbirth self-efficacy (CBSE). This randomized controlled clinical trial was conducted on 153 pregnant women referred to health centers in the city of Miandoab, Iran in 2015-2016. Participants were assigned into two intervention groups (e-learning and educational booklet) and the control group. A single face-to-face session was held for intervention groups about the management of labor pain in 30-34 weeks of pregnancy and the booklet and software were provided. The CBSE questionnaire was filled out by the participants before intervention and active phase of labor at 4-5 cm dilatation of cervix. One-way ANOVA and ANCOVA test with adjusting the baseline scores were used to compare the mean score of self-efficacy among study groups respectively before and after the intervention. There was no significant difference between the three groups in terms of socio-demographic characteristics (p > 0.05). After the intervention, the mean score of the CBSE in the educational booklet group (adjusted mean difference: 113.4; confidence interval 95%: 100.7-126.1) and e-learning group (159.3; 146.5-172.0) was significantly higher than the control group. Also, the mean score of the CBSE in the e-learning group had a significant increase compared to the educational booklet group (45.9; 33.0-58.7). The results indicate that e-learning and educational booklet are effective in enhancing mothers' CBSE. Thus, the mothers are recommended to use these teaching methods.

The present study was conducted to compare the cleaning efficacy (debris and smear layer removal) of hand and two NiTi rotary instrumentation systems (K3 and ProTaper). Sixty single rooted human maxillary anterior teeth decoronated at the cementoenamel junction were used. All the specimens were divided into four groups of 15 teeth each, group I--ProTaper rotary instrumentation done, group II--K3 rotary instrumentation done, group III--Stainless steel K-file instrumentation done, group IV--root canal irrigation without instrumentation. Root canal preparation was done in a crown down manner and 3% sodium hypochlorite was used as irrigant after each file followed by final rinse with 5 ml of 17% EDTA solution, then specimens were scanning electron microscopic (SEM) examination. Statistical analysis was done using one-way ANOVA followed by post hoc Tukey's HSD test. Group I showed highly statistical significant difference compared to other groups. There was no statistically significant difference considering smear layer at any levels among the groups with no smear layer formation in group IV. ProTaper rotary instrumentation showed the maximum cleaning efficacy followed by K3 rotary instrumentation in the coronal, middle and apical thirds of the root canal. ProTaper rotary instruments are more efficient than hand and K3 rotary instruments during root canal treatment.

Topical minoxidil has been successfully used to treat androgenetic alopecia. It can also be applied to enhance eyebrows. However, there is no study comparing minoxidil lotion with placebo for eyebrow enhancement. In this trial, we determined the efficacy and safety of minoxidil 2% lotion for eyebrow enhancement compared with placebo. Forty patients were randomized for minoxidil on the eyebrow on one side of the face and placebo on the other. Efficacy was evaluated by global photographic assessment, eyebrow diameter, eyebrow count and subject's satisfaction. Side-effects were also evaluated. Thirty-nine patients (97.5%) completed the study. After 16 weeks, the minoxidil group achieved significantly better results in all measured outcomes compared to the placebo group. Side-effects were minor and did not preclude patients from continuing the study. Our study suggests that minoxidil 2% lotion is a safe and effective treatment for eyebrow hypotrichosis. © 2014 Japanese Dermatological Association.

Fear of birth and low childbirth self-efficacy is predictive of post-traumatic stress disorder symptoms following childbirth. The efficacy of antenatal education classes on fear of birth and childbirth self-efficacy has been supported; however, the effectiveness of antenatal classes on post-traumatic stress disorder symptoms after childbirth has received relatively little research attention. This study examined the effects of antenatal education on fear of childbirth, maternal self-efficacy and post-traumatic stress disorder symptoms following childbirth. Quasi-experimental study. The study was conducted in a city located in the Middle Anatolia region of Turkey and data were collected between December 2013 and May 2015. Two groups of women were compared-an antenatal education intervention group (n=44), and a routine prenatal care control group (n=46). The Wijma Delivery Expectancy/Experience Questionnaire, Version A and B, Childbirth Self-efficacy Inventory and Impact of Event Scale-Revised was used to assess fear of childbirth, maternal self-efficacy and PTSD symptoms following childbirth. Compared to the control group, women who attended antenatal education had greater childbirth self-efficacy, greater perceived support and control in birth, and less fear of birth and post-traumatic stress disorder symptoms following childbirth (all comparisons, ppost-traumatic stress disorder symptoms after childbirth.

Full Text Available Objectives. Overactive bladder (OAB is a chronic disease, but comparative trials of anticholinergics, which are commonly used for treatment of OAB, have generally been performed for up to 12 weeks only. There is no comparative study of a long-term intervention. Methods. We conducted a 52-week prospective randomized comparative study to evaluate the efficacy and tolerability of two anticholinergics. Results. Forty-one Japanese patients with untreated OAB were randomly assigned to imidafenacin and solifenacin groups. There was no difference in OABSS and KHQ scores between the two groups, but the severity and incidence of adverse events caused by the anticholinergics showed increased differences between the groups with time. The severity of dry mouth and the incidence of constipation were significantly lower in the imidafenacin group (=0.0092 and =0.0013, resp.. Conclusions. This study is the first long-term trial to show differences in the properties of anticholinergics that were not detected in short-term studies. Since OAB is a chronic disease, we conclude that imidafenacin is preferable to solifenacin from a perspective of safety.

Yersinia pestis, the bacterium that causes plague, is a potential agent of bioterrorism. Streptomycin is the "gold standard" for the treatment of plague infections in humans, but the drug is not available in many countries, and resistance to this antibiotic occurs naturally and has been generated in the laboratory. Other antibiotics have been shown to be active against Y. pestis in vitro and in vivo. However, the relative efficacies of clinically prescribed regimens of these antibiotics with streptomycin and with each other for the killing of Yersinia pestis are unknown. The efficacies of simulated pharmacokinetic profiles for human 10-day clinical regimens of ampicillin, meropenem, moxifloxacin, ciprofloxacin, and gentamicin were compared with the gold standard, streptomycin, for killing of Yersinia pestis in an in vitro pharmacodynamic model. Resistance amplification with therapy was also assessed. Streptomycin killed the microbe in one trial but failed due to resistance amplification in the second trial. In two trials, the other antibiotics consistently reduced the bacterial densities within the pharmacodynamic systems from 10⁸ CFU/ml to undetectable levels (pestis and deserve further evaluation.

Abatacept (ABA) has recently been proposed as second-line treatment in patients with juvenile idiopathic arthritis (JIA)-associated uveitis refractory to anti-tumor necrosis factor-α (anti-TNF) agents, but little is known about its efficacy as a first-line approach. The aim of the present study was to compare the safety and efficacy of ABA as a first-line biological agent (ABA-1) with that of ABA as a second-line treatment after 1 or more anti-TNF agents (ABA-2), in patients with severe JIA-related uveitis. In this multicenter study, we collected data on patients with severe JIA-related uveitis treated with ABA as a first-line or second-line biological agent. Changes in frequency of uveitis flares/year and ocular complications before and after ABA treatment, clinical remission, and side effects were recorded. Thirty-five patients with a mean age of 10.8 years were treated with ABA for a mean period of 19.6 months. In 4 patients, ABA administration was discontinued, owing to inefficacy on arthritis in 3 cases and allergic reaction in 1. Thirty-one patients, 14 in the ABA-1 group and 17 in the ABA-2 group, completed the 12-month followup period; of these, 17 (54.8%) had clinical remission. The mean frequency of uveitis flares decreased from 4.1 to 1.2 in the ABA-1 group (p = 0.002) and from 3.7 to 1.2 in the ABA-2 group (p = 0.004). Preexisting ocular complications improved or remained stable in all but 5 patients, all in the ABA-2 group. No significant difference was found between the efficacy of the 2 treatment modalities. ABA confirmed its good safety profile. ABA, used as first-line biological treatment or after 1 or more anti-TNF agents, induces a comparable improvement in severe refractory JIA-related uveitis.

There have been inconsistent findings from randomised controlled trials (RCTs) and systematic reviews on the efficacies of selective serotonin reuptake inhibitors (SSRIs) as the first-line treatment of major depressive disorder (MDD). Besides inconsistencies among randomised controlled trials (RCTs), their risks of bias and evidence grading have seldom been evaluated in meta-analysis. This study aims to compare the efficacy of SSRIs by conducting a Bayesian network meta-analysis, which will be the most comprehensive evaluation of evidence to resolve the inconsistency among previous studies. SSRIs including citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline and vilazodone have been selected. Systematic database searching and screening will be conducted for the RCTs on drug treatment of patients with MDD according to pre-specified search strategies and selection criteria. PubMed, the Cochrane Library, EMBASE, ScienceDirect, the US Food and Drug Administration Website, ClinicalTrial.gov and WHO Clinical Trials will be searched. Outcome data including Hamilton Depression Rating Scale (HDRS), Montgomery-Åsberg Depression Rating Scale (MADRS) and Clinical Global Impression (CGI) from eligible RCTs will be extracted. The outcomes will be analysed as ORs and mean differences under a random-effects model. A Bayesian network meta-analysis will be conducted with WinBUGS software, to compare the efficacies of SSRIs. Subgroup and sensitivity analysis will be performed to explain the study heterogeneity and evaluate the robustness of the results. Meta-regression analysis will be conducted to determine the possible factors affecting the efficacy outcomes. The Cochrane risk of bias assessment tool will be used to assess the RCT quality, and the Grading of Recommendation, Assessment, Development and Evaluation will be used to assess the strength of evidence from the meta-analysis.

Objective To compare the safety and efficacy of antibiotic treatment versus appendicectomy for the primary treatment of uncomplicated acute appendicitis. Design Meta-analysis of randomised controlled trials. Population Randomised controlled trials of adult patients presenting with uncomplicated acute appendicitis, diagnosed by haematological and radiological investigations. Interventions Antibiotic treatment versus appendicectomy. Outcome measures The primary outcome measure was complications. The secondary outcome measures were efficacy of treatment, length of stay, and incidence of complicated appendicitis and readmissions. Results Four randomised controlled trials with a total of 900 patients (470 antibiotic treatment, 430 appendicectomy) met the inclusion criteria. Antibiotic treatment was associated with a 63% (277/438) success rate at one year. Meta-analysis of complications showed a relative risk reduction of 31% for antibiotic treatment compared with appendicectomy (risk ratio (Mantel-Haenszel, fixed) 0.69 (95% confidence interval 0.54 to 0.89); I2=0%; P=0.004). A secondary analysis, excluding the study with crossover of patients between the two interventions after randomisation, showed a significant relative risk reduction of 39% for antibiotic therapy (risk ratio 0.61 (0.40 to 0.92); I2=0%; P=0.02). Of the 65 (20%) patients who had appendicectomy after readmission, nine had perforated appendicitis and four had gangrenous appendicitis. No significant differences were seen for treatment efficacy, length of stay, or risk of developing complicated appendicitis. Conclusion Antibiotics are both effective and safe as primary treatment for patients with uncomplicated acute appendicitis. Initial antibiotic treatment merits consideration as a primary treatment option for early uncomplicated appendicitis. PMID:22491789

Full Text Available Aims: In spite of folkloric use of the root of Carpolobia lutea as sexual stimulant in man, there has been limited scientific proof of its efficacy. This study evaluates efficacy of methanol extract of Carpolobia lutea root (MECLR on sexual activity of male rabbits. Methods: Twenty adult male rabbits were grouped into four of five rabbits each. Groups 1-4 were treated orally for 28 days with 2ml/kg 1% tween 20 (vehicle, 40mg/kg MECLR, 80mg/kg MECLR, and 0.5mg/kg sildenafil citrate respectively. Sexual activities of males from each group was assessed by cohabiting them with sexually receptive female at estrus on days 0,1,3 and 5 using digital camera mounted on mating arena. Serum testosterone and nitric oxide concentration of the corpora cavernosa homogenates were also determined. Results: MECLR caused a dose dependent significant increase in mount frequency, intromission frequency and ejaculatory latency, while it reduced mount latency, intromission latency and post ejaculatory latency (similar to sildenafil citrate when compared with the control. MECLR also caused a significant increase in nitric oxide concentration in corpora cavernosa but no change in serum testosterone concentration. Conclusions: Results suggest that MECLR enhances male sexual activity possibly by augmenting nitric oxide concentration. This study thus provides novel scientific rationale for the use of Carpolobia lutea in the management of penile erectile dysfunction and impaired libido.

Although there are several methods to treat Verruca plana, warts do not respond well to the common therapeutic options. In this study, we compared the safety and efficacy of 10% trichloroacetic acid, 25% trichloroacetic acid, and cryotherapy for the treatment of warts caused by Verruca plana. Ten percent and 25% trichloroacetic acid were applied to warts weekly until all lesions cleared. Cryotherapy was performed by liquid nitrogen spray for 5-10 seconds for each lesion per week until the lesions cleared. The number of Verruca plana lesions and adverse effects were evaluated five times during the treatment (the initial visit, week 2, week 4, week 6, and week 8). The number of lesions decreased through week 8 for all three treatments, and the reductions in the mean numbers of lesions were statistically similar (p > 0.05). Those in the cryotherapy group exhibited more erythema, pain, erosions, bullae, and hyperpigmentation (p cryotherapy group (p cryotherapy are effective methods to treat Verruca plana. 10% trichloroacetic acid offers a safer and easier treatment than either 25% trichloroacetic acid or cryotherapy.

ABP 501 is a Food and Drug Administration-approved biosimilar to adalimumab; structural, functional and pharmacokinetic evaluations have shown that the two are highly similar. We report results from a phase III study comparing efficacy, safety and immunogenicity between ABP 501 and adalimumab. In this randomised, double-blind, active comparator-controlled, 26-week equivalence study, patients with moderate to severe active rheumatoid arthritis (RA) despite methotrexate were randomised (1:1) to ABP 501 or adalimumab (40 mg) every 2 weeks. Primary endpoint was risk ratio (RR) of ACR20 between groups at week 24. Primary hypothesis that the treatments were equivalent would be confirmed if the 90% CI for RR of ACR20 at week 24 fell between 0.738 and 1.355, demonstrating that ABP 501 is similar to adalimumab. Secondary endpoints included Disease Activity Score 28-joint count-C reactive protein (DAS28-CRP). Safety was assessed via adverse events (AEs) and laboratory evaluations. Antidrug antibodies were assessed to determine immunogenicity. A total of 526 patients were randomised (n=264, ABP 501; n=262 adalimumab) and 494 completed the study. ACR20 response at week 24 was 74.6% (ABP 501) and 72.4% (adalimumab). At week 24, the RR of ACR20 (90% CI) between groups was 1.039 (0.954, 1.133), confirming the primary hypothesis. Changes from baseline in DAS28-CRP, ACR50 and ACR70 were similar. There were no clinically meaningful differences in AEs and laboratory abnormalities. A total of 38.3% (ABP 501) and 38.2% (adalimumab) of patients tested positive for binding antidrug antibodies. Results from this study demonstrate that ABP 501 is similar to adalimumab in clinical efficacy, safety and immunogenicity in patients with moderate to severe RA.

We compared the efficacy of multimedia learning modules with traditional textbooks for the first few topics of a calculus-based introductory electricity and magnetism course. Students were randomly assigned to three groups. One group received the multimedia learning module presentations, and the other two received the presentations via written text. All students were then tested on their learning immediately following the presentations as well as 2weeks later. The students receiving the multimedia learning modules performed significantly better on both tests than the students experiencing the text-based presentations.

The aim of the study was to compare knowledge and awareness of heart attacks/heart disease and perceived risk for future heart attack in Asian/Pacific Islander women, compared to other racial and ethnic groups. In this cross-sectional study, 318 women enrolled in a mobile phone-based physical activity education trial were analyzed. Heart attack knowledge, self-efficacy for recognizing and responding to heart attack symptoms, and perceived risk for a future heart attack were measured. Analyses were conducted using logistic, proportional odds, and linear regression models, depending on the outcome and adjusting for age. Pairwise differences between Asian/Pacific Islanders and the other four groups were assessed using a Bonferroni correction (p Asian/Pacific Islander women had significantly lower total scores for knowledge of heart attack and self-efficacy for heart attack recognition and care seeking behavior compared to the Caucasian women (p = 0.001 and p = 0.002, respectively). However, perceived risk did not differ among the groups. Forty-six percent of the Asian American women, compared to 25% of Caucasian women, falsely believed "breast cancer is the number one cause of death for women (p = 0.002)." In addition, Asian/Pacific Islander women were less likely to report "arm pain, numbness, tingling, or radiating" as one of the heart attack symptoms compared to the Caucasian and the multiracial group (34%, 63% [p Asian/Pacific Islander women and Caucasian women.

The present study compares the safety and efficacy of a needle-free, intradermal Mycoplasma hyopneumoniae vaccine to an intramuscular one. 420 piglets (21+3 days of age) were randomly assigned to two vaccination groups (intradermal vaccination V1 (n=138), intramuscular vaccination V2 (n=144)) and one unvaccinated control group (CG, n=138). As safety parameters clinical observations, local injection site reactions (ISR) and rectal temperatures were assessed. Average daily weight gain (ADWG) and pneumonic lung lesions (LL) were measured as efficacy parameters. ISRs were minor in V1. After both vaccinations, no adverse impact on appetite was observed and mean rectal temperatures remained within physiological range. ADWG during the fattening period was significantly higher in vaccinated groups (V1: 913.4 g, V2: 924.5 g) compared with CG (875.6 g). No differences in ADWG were observed between V1 and V2. Vaccinated pigs had a significantly reduced mean extent of LL compared with CG. V1 was superior in reducing the extent and prevalence of LL compared with V2. These results reveal that a needle-free intradermal vaccination is safe and efficacious in reducing both the prevalence and extent of lung lesions, as well as in improving performance parameters, in a farrow-to-finish farm with a late onset of M hyopneumonia e infection. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

Roberts, Megan Rae

This study focuses on an analysis of a professional development program known as lesson study via data obtained during an in-service professional development program for secondary school science teachers. The purpose of this study was to examine the self-efficacy beliefs of one group of science teachers related to their experiences in a lesson study. Another purpose for this research, aligned with the first, included a theoretical analysis of the lesson study construct to see if its design promoted positive self-efficacy beliefs of its participants. The research is framed within the context of social constructivism and self-efficacy and is qualitative in nature and utilized descriptive analysis as a means of research. Case studies were conducted detailing two of the six participants. Data sources included researcher field notes and transcriptions of all planning and debriefing sessions; individual interviews with each participant and the schools' principal; a participant questionnaire, and the Science Teaching Efficacy Belief Instrument. Themes that emerged included the positive perceptions of lesson study as a collaborative and teacher-centered experience; the understanding that lesson study can instill a sense of professionalism to those who participate in the process; the sense that discussing student learning using objective observations from classroom is a powerful way to assess learning and uncover personal teacher beliefs; and the insight that the time commitment that lesson study requires can inhibit teachers and schools from sustaining it as a form of on-going professional development. Although these themes are consistent with the research on lesson study in Japan and elsewhere in the United States, they also extend the research on self-efficacy and science teacher professional development. In the end, this study supported some of the conclusions of the self-efficacy research as it relates to professional development while also adding that interpersonal

Full Text Available Recent epidemiological developments demonstrated that gene segments of swine influenza A viruses can account for antigenic changes as well as reduced drug susceptibility of pandemic influenza A viruses. This raises questions about the efficacy of preventive measures against swine influenza A viruses. Here, the protective effect of vaccination was compared with that of prophylactic Tamiflu® treatment against two Eurasian swine influenza A viruses. 11-week-old pigs were infected by aerosol nebulisation with high doses of influenza virus A/swine/Potsdam/15/1981 (H1N1/1981, heterologous challenge to H1N1 vaccine strain and A/swine/Bakum/1832/2000 (H1N2/2000, homologous challenge to H1N2 vaccine strain in two independent trials. In each trial (i 10 pigs were vaccinated twice with a trivalent vaccine (RESPIPORC® FLU3; 28 and 7 days before infection, (ii another 10 pigs received 150 mg/day of Tamiflu® for 5 days starting 12 h before infection, and (iii 12 virus-infected pigs were left unvaccinated and untreated and served as controls. Both viruses replicated efficiently in porcine respiratory organs causing influenza with fever, dyspnoea, and pneumonia. Tamiflu® treatment as well as vaccination prevented clinical signs and significantly reduced virus shedding. Whereas after homologous challenge with H1N2/2000 no infectious virus in lung and hardly any lung inflammation were detected, the virus titre was not and the lung pathology was only partially reduced in H1N1/1981, heterologous challenged pigs. Tamiflu® application did not affect these study parameters. In conclusion, all tested preventive measures provided protection against disease. Vaccination additionally prevented virus replication and histopathological changes in the lung of homologous challenged pigs.

Although percutaneous abscess drainage has become and accepted alternative from of therapy for selected patients with abscess, it is well known that there are several factors in the failure of adequate drainage such as pre- and post-procedural management, technique itself, various features of abscess, and selection and application of catheters. Among these factors, we made an experiment about drainage efficacy of commonly used various catheters with different viscosities of water-glycerin solution under the two different pressure gradients. The experimental values of flow rate were very lower than the calculated values. An efficacy of experimental value was 4-14%. Because the inner diameter of fittings and stopcocks was usually smaller than the inner diameter of catheters, these factors also affected the drain efficacy. Finally, we thought that it will be very helpful to the treatment of patient as well as to study about the catheter drainage, if the drain efficacy of individual catheters has been notified.

The benefits of posterior lumbar fusion surgery with orthotopic paraspinal muscle-pediculated bone flaps are well established. However, the problem of non-union due to mechanical support is not completely resolved. The aim of the study was to compare the efficacy of polyether ether ketone (PEEK) rod device with conventional titanium devices in the posterior lumbar fusion surgery with orthotopic paraspinal muscle-pediculated bone flaps. This was a randomized controlled study with an experimental animal model. Thirty-two mongrel dogs were randomly divided into two groups-control group (n = 16), which received the titanium device and the treatment group (n = 16), which received PEEK rods. The animals were sacrificed 8 or 16 weeks after surgery. Lumbar spines of dogs in both groups were removed, harvested, and assessed for radiographic, biomechanical, and histological changes. Results in the current study indicated that there was no significant difference in the lumbar spine of the control and treatment groups in terms of radiographic, manual palpation, and gross examination. However, certain parameters of biomechanical testing showed significant differences (p < 0.05) in stiffness and displacement, revealing a better fusion (treatment group showed decreased stiffness with decreased displacement) of the bone graft. Similarly, the histological analysis also revealed a significant fusion mass in both treatment and control groups (p < 0.05). These findings revealed that fixation using PEEK connecting rod could improve the union of the bone graft in the posterior lumbar spine fusion surgery compared with that of the titanium rod fixation.

Arthropod Pest Control for UK Oilseed Rape - Comparing Insecticide Efficacies, Side Effects and Alternatives.

Directory of Open Access Journals (Sweden)

Han Zhang

Full Text Available Oilseed rape (Brassica napus is an important combinable break crop in the UK, which is largely protected from arthropod pests by insecticidal chemicals. Despite ongoing debate regarding the use of neonicotinoids, the dominant seed treatment ingredients used for this crop, there is little publicly available data comparing the efficacy of insecticides in controlling key arthropod pests or comparing the impacts on non-target species and the wider environment. To provide an insight into these matters, a UK-wide expert survey targeting agronomists and entomologists was conducted from March to June 2015. Based on the opinions of 90 respondents, an average of 20% yield loss caused by the key arthropod pests was expected to have occurred in the absence of insecticide treatments. Relatively older chemical groups were perceived to have lower efficacy for target pests than newer ones, partly due to the development of insecticide resistance. Without neonicotinoid seed treatments, a lack of good control for cabbage stem flea beetle was perceived. Wide spectrum foliar insecticide sprays were perceived to have significantly greater negative impacts than seed treatments on users' health, natural enemies, pollinators, soil and water, and many foliar active ingredients have had potential risks for non-target arthropod species in UK oilseed rape fields for the past 25 years. Overall, 72% of respondents opposed the neonicotinoid restriction, while 10% supported it. Opposition and support of the restriction were largely based on concerns for pollinators and the wider environment, highlighting the uncertainty over the side effects of neonicotinoid use. More people from the government and research institutes leaned towards neutrality over the issue, compared to those directly involved in growing the crop. Neonicotinoid restriction was expected to result in greater effort and expenditure on pest control and lower production (0-1 t/ha less. Alternatives for future

To compare the efficacy of preoperative submucosal injection of 4 mg of dexamethasone versus 40 mg of methylprednisolone in reducing postoperative sequelae after surgical removal of impacted mandibular third molars. This prospective, randomized, double-blind study included 65 patients who required surgical removal of impacted mandibular third molars with Class II or position B impaction (Pell and Gregory classification). Patients were randomly assigned to 1 of 3 groups: dexamethasone, methylprednisolone, or placebo (control). Surgery was performed with patients under local anesthesia. Baseline measurements were obtained preoperatively, and subsequent assessments were made on postoperative day 1, 2, 5, and 7 to measure postoperative facial swelling by use of 2 linear measurements: interincisal mouth opening width and visual analog scale score for pain. The amount of analgesics consumed was recorded. Wound healing also was assessed on postoperative day 7. Descriptive and multivariate statistics were computed, and significance was set at P Kruskal-Wallis test), whereas the methylprednisolone group had significantly less pain (P Kruskal-Wallis test) and consumed a lower amount of analgesics (P test) during the early postoperative days. The study findings suggest that a single preoperative dose of dexamethasone versus methylprednisolone was equally effective in reducing postoperative swelling and trismus. Pain control by these corticosteroids, however, was variable. Copyright © 2017 American Association of Oral and Maxillofacial Surgeons. Published by Elsevier Inc. All rights reserved.

OBJECTIVE: To examine and compare the safety and efficacy of extended treatment with dabigatran, apixaban, rivaroxaban and warfarin in patients with unprovoked venous thromboembolism. METHODS: PubMed and Embase were searched for randomized clinical trials reporting on the use of direct oral...... anticoagulants (DOACs) and warfarin for the extended treatment of VTE. Meta-analysis was performed on studies reporting similar study design and comparator. RESULTS: A total of 729 articles were identified and 5 studies covering 6 randomized clinical trials met the eligibility criteria and were included...... in the study. 5 studies were included in the meta-analysis. Results from the meta-analysis showed that the extended use of DOACs and warfarin significantly decreased the risk of recurrent VTE with 83 % when compared placebo. Warfarin (RR: 0.03, CI: 0.00-0.49) and dabigatran (RR: 0.08, CI: 0.03-0.27) showed...

Striae distensae are dermal scars with a linear atrophic depression. The exact origin of striae distensae remains unrevealed, but low expression of collagen and fibronectin genes in the affected tissue was found. Several treatment modalities have been proposed, yet no consistent modality is available. To evaluate and compare the efficacy and safety of carboxytherapy vs platelet-rich plasma (PRP) in treatment of stretch marks. This study included 20 patients with striae alba. Every patient received treatment in the form of PRP injection in their right side (group A) and carboxytherapy session in their left side (group B) every 3-4 weeks for 4 sessions. Skin biopsies were taken before and after treatment, and they were subjected to fibronectin immunohistochemical stain. There was a significant improvement in striae alba in both groups after than before treatment. There was no significant difference between both groups as regards either percentage of improvement, response (grading scale), or patient satisfaction. The fibronectin-stained area was significantly higher in both groups after than before treatment, and it was significantly higher after treatment in group (B) than group (A). Both methods were safe and effective with minimal side effects. There was no significant difference between both methods of treatments. This was confirmed histopathologically by fibronectin expression which is found to be low in striae and increased significantly after treatment. But fibronectin expression was higher in group (B) than (A). © 2018 Wiley Periodicals, Inc.

Full Text Available Introduction: Probiotic technology represents a breakthrough approach to maintaining oral health by utilizing natural beneficial bacteria commonly found in healthy mouths to provide a natural defense against those bacteria thought to be harmful to teeth and gums. However, data are still sparse on the probiotic action in the oral cavity. The review article on probiotics in children published by Twetman and Stecksen- Blicks in 2008 showed only one study of dental interest on probiotics in children. Aim and Objectives: The present study evaluated clinically the efficacy of a probiotic and chlorhexidine mouth rinses on plaque and gingival accumulation in children. The trial design is a double-blind parallel group, 14 days comparative study between a probiotic mouth rinse and a chlorhexidine mouth rinse, which included 45 healthy children in the age group of 6-8 years. Results: The Probiotic and Chlorhexidine groups had less plaque accumulations compared with the Control group at the end of 14 years (P < 0.001 and P < 0.001, respectively. But, unlike the plaque score, there was a significant difference in the Gingival Index between the Probiotic and the Chlorhexidine groups (P = 0.009, Probiotic group being better than the Chlorhexidine group (mean = 0.2300 and 0.6805, respectively. Conclusion: The Probiotic mouth rinse was found effective in reducing plaque accumulation and gingival inflammation. Therefore, probiotic mouth rinse obviously has a potential therapeutic value and further long-term study is recommended to determine its efficacy.

Dermatophytes are the most frequently implicated agents in toenail onychomycosis and oral terbinafine has shown the best cure rates in this condition. The pharmacokinetics of terbinafine favors its efficacy in pulse dosing. To compare the efficacy of terbinafine in continuous and pulse dosing schedules in the treatment of toenail dermatophytosis. Seventy-six patients of potassium hydroxide (KOH) and culture positive dermatophyte toenail onychomycosis were randomly allocated to two treatment groups receiving either continuous terbinafine 250 mg daily for 12 weeks or 3 pulses of terbinafine (each of 500 mg daily for a week) repeated every 4 weeks. Patients were followed up at 4, 8 and 12 weeks during treatment and post-treatment at 24 weeks. At each visit, a KOH mount and culture were performed. In each patient, improvement in a target nail was assessed using a clinical score; total scores for all nails and global assessments by physician and patient were also recorded. Mycological, clinical and complete cure rates, clinical effectivity and treatment failure rates were then compared. The declines in target nail and total scores from baseline were significant at each follow-up visit in both the treatment groups. However, the inter-group difference was statistically insignificant. The same was true for global assessment indices, clinical effectivity as well as clinical, mycological, and complete cure rates. The short follow-up in our study may have led to lower cure rates being recorded. Terbinafine in pulse dosing is as effective as continuous dosing in the treatment of dermatophyte toenail onychomycosis.

Full Text Available Abstract Background People with diabetes and peripheral neuropathy often do not implement the foot-care behavioural strategies that are suggested by many health professionals. The concept of self-efficacy has been shown to be an effective predictor of behaviour in many areas of health. This study investigated the relationships between foot-care self-efficacy beliefs, self-reported foot-care behaviour and history of diabetes-related foot pathology in people with diabetes and loss of protective sensation in their feet. Methods Ninety-six participants were included in this cross-sectional study undertaken in a regional city of Australia. All participants had diabetes and clinically diagnosed loss of protective sensation in their feet. The participants completed a self-report pen-paper questionnaire regarding foot-care self efficacy beliefs (the "Foot Care Confidence Scale" and two aspects of actual foot-care behaviour-preventative behaviour and potentially damaging behaviour. Pearson correlation coefficients were then calculated to determine the association between foot-care self-efficacy beliefs and actual reported foot-care behaviour. Multiple analysis of variance was undertaken to compare mean self-efficacy and behaviour subscale scores for those with a history of foot pathology, and those that did not. Results A small positive correlation (r = 0.2, p = 0.05 was found between self-efficacy beliefs and preventative behaviour. There was no association between self-efficacy beliefs and potentially damaging behaviour. There was no difference in self-efficacy beliefs in people that had a history of foot pathology compared to those that did not. Conclusion There is little association between foot-care self-efficacy beliefs and actual foot-care behaviour. The usefulness of measuring foot-care self-efficacy beliefs to assess actual self foot-care behaviour using currently available instruments is limited in people with diabetes and loss of protective

Prokinetic drugs are widely used for treatment of non-ulcer dyspepsia (NUD). To assess the efficacy and tolerability of a new prokinetic agent, itopride hydrochloride in patients of NUD and compare it with domperidone. Fifty-six patients who fulfilled the inclusion and exclusion criteria were enrolled in the study. Patients underwent upper gastrointestinal endoscopy to rule out organic pathology as a cause for their symptoms. The patient's symptoms were graded on a 4-point scale (0 to 3) at the beginning of treatment and at the end of Week-one and Week-two Patients were randomly allocated to receive either one tablet of itopride hydrochloride 50mg three times daily or one tablet of domperidone 10mg three times daily for two weeks. Pre-treatment and post-treatment hemogram, liver function and renal function tests, prolactin level and ECG were done in all patients. The response to therapy was evaluated by assessing the relief of symptoms at the end of two weeks on a 5-point scale. Statistical analysis was done using two-tailed paired t-test; Wilcoxon matched pairs ranks sum test, Mann-Whitney-U test and chi-square test as applicable. Of the fifty-five patients enrolled in the study (age range of 18-60 yrs, median age of 35yrs), 26 were males and twenty nine were females. They had a median duration of symptoms for 4 weeks. Twenty-seven patients received itopride and 28 received domperidone. One patient did not follow up in the domperidone group, thus 54 patients were evaluable for analysis. Moderate to complete symptomatic relief was observed in 22 (81%) patients in the itopride group and 19 patients (70%) in the domperidone group (p > 0.05, NS). Both the drugs were well tolerated and neither caused prolongation of QT interval nor any abnormality in any serum biochemistry values. Therapy with itopride resulted in good symptomatic relief, was safe, well tolerated and comparable in efficacy to domperidone in relieving the symptoms of NUD. By virtue of its efficacy and

Full Text Available This study treats the members in nonprofit organizations (NPOs as subjects, and explores the origination, planning, control, and completion of project management in NPOs, as well as the general performance of organizational efficacy, such as environmental satisfaction, organizational atmosphere, operational performance, job engagement, and work quality. It also probes into the relationship and effect. By various research methods, such as literature review and questionnaire survey, this study attempts to determine if project management in NPOs can significantly enhance organizational efficacy. This study finds that different NPOs have significant differences in the general performance of project management and organizational efficacy. When the performance of project management in NPOs is more significant, organizational efficacy is higher. Project management in NPOs has a significant path relationship to organizational efficacy; therefore, reinforcement of vocational training in the project management of NPOs could improve performance, which would have significant effect on enhancing organizational efficacy.

Our objective was to compare the efficacy of selenium sulfide shampoo 1% and ciclopirox shampoo 1% as adjunctive treatments for tinea capitis in children. Forty children aged 1-11 years with clinically diagnosed tinea capitis were randomized to receive selenium sulfide shampoo 1% or ciclopirox shampoo 1% twice a week as adjuncts to an 8-week course of ultramicronized griseofulvin dosed at 10-12 mg/kg/day. At weeks 2, 4, and 8, subjects returned to the clinic for evaluation and scalp cultures. Subjects then returned for follow-up visits 4 weeks after completing treatment. Overall, by 8 weeks, 30 of 33 (90.9%) treated children demonstrated mycological cure. Selenium sulfide shampoo 1% and ciclopirox shampoo 1% were equally effective as adjunctive treatments for tinea capitis in children in our study. © 2010 Wiley Periodicals, Inc.

Full Text Available BACKGROUND Postoperative nausea and vomiting is one of the many side effects of patients undergoing laparoscopic surgeries under general anaesthesia. Its prevention is major concern of anaesthesiologist managing the case. To this effect, many drugs have been used and use of serotonin (5-HT3 receptor antagonists like ondansetron, granisetron, tropisetron and dolasetron has been compared in many studies. This study was undertaken to study the efficacy of ondansetron, granisetron and their side effects. MATERIALS AND METHODS Patients were allocated into two groups, each group consisting of 50 patients. Group O received ondansetron 4 mg IV before induction. Group G received granisetron 1 mg IV before induction. The incidences of PONV were recorded within the first 24 hours after surgery at intervals of 0-2 hours, 3 hours, 6 hours, 12 hours and 24 hours. Episodes of PONV were identified by spontaneous complaints by the patients or by direct questioning. RESULTS In present study, incidence of nausea at different intervals in granisetron group is less than in the ondansetron group, which is statistically significant (p <0.05. The incidence of nausea was 36% in Group O and 12% in Group G, which was significantly low. The incidence of retching was 22% in Group O and it was less in Group G that is 2%. Greater percentage of patients in Group O (16% experienced vomiting compared to Group G (2%. CONCLUSION The overall frequency of Postoperative Nausea and Vomiting (PONV was less in Group G than Group O.

Self-efficacy is posited in social cognitive theory as fundamental to behavior change. Few health behavior studies have examined self-efficacy prospectively, viewed it as part of a reciprocal behavioral process, or compared self-efficacy beliefs in the same population across different behaviors. This article first discusses self-efficacy in its theoretical context and reviews the available prospective studies. Second, it explores self-efficacy as a predictor of disease management behaviors in 570 older women with heart disease. Although the R2 statistics in each case were modest, the construct is shown to be a statistically significant (pmanagement behaviors: using medicine as prescribed, getting adequate exercise, managing stress, and following a recommended diet. Building self-efficacy is likely a reasonable starting point for interventions aiming to enhance heart disease management behaviors of mature female patients.

Full Text Available The epidemiology of orf virus infection in Saudi Arabia (SA has been researched since 1990. The results obtained during this period indicate that the disease is widespread, has great economic impact and that no vaccine has been used against it. The present study compares the immunogenicity and protective efficacy of three locally developed live orf virus vaccines. Two of them differ in their passage history in Vero cell culture and the third was used as a virulent virus in glycerine buffer. To the best of the authors’ knowledge, no similar comparative study has been conducted in the Middle East utilising three types of vaccines prepared from the same virus strain. Selection of the candidate seed orf virus and performance of the quality control tests were as laid out by the OIE for veterinary vaccine production. The vaccine seed virus was a field orf virus isolated from a previous orf outbreak in Saudi Arabia. A simple novel formula was developed to calculate the rate of reduction in the healing time (RHT % in the challenged sheep. This allowed direct comparison of the efficacy of the three types of vaccines employed in the present study. The efficacy of each vaccine was tested on a cohort of local Noemi sheep.

Curcumin, the major active principle of Curcuma longa, is one of the promising, plant-derived, chemopreventive agents being studied for its anticarcinogenic and antioxidant properties. Hence, in our study, we aimed at testing the antiproliferative efficacy of an o-hydroxyl substituted analog of curcumin, bis demethoxy curcumin analog (BDMC-A), and comparing its efficacy with that of curcumin. BDMC-A was synthesised with a yield of 78% and 98% purity. Hep-2 cells and the MTT cell viability assay were used to examine cell proliferation. LDH assay and cell counts were performed to assess the cytotoxicity and anti-proliferative effects of the compound, respectively. Flow cytometry followed by Western blot were performed to investigate the cell cycle distribution. BDMC-A inhibited cell proliferation at a much lower concentration (IC50 20 microM) than curcumin (IC50 50 microM). Similar effects were observed in the LDH release and cell count assays. Flow cytometric studies using propidium iodide showed accumulation of cells in the G0/G1 phase and the arrest was further confirmed by immunoblotting of protein cyclin D1. BDMC-A was more potent in inhibiting the cells at a lower dose when compared with curcumin. Our results showed that the analog of curcumin is likely to possess more efficacy compared with curcumin in inhibiting cancer.

Multiple comparisons in drug efficacy studies: scientific or marketing principles?

Science.gov (United States)

Leo, Jonathan

2004-01-01

When researchers design an experiment to compare a given medication to another medication, a behavioral therapy, or a placebo, the experiment often involves numerous comparisons. For instance, there may be several different evaluation methods, raters, and time points. Although scientifically justified, such comparisons can be abused in the interests of drug marketing. This article provides two recent examples of such questionable practices. The first involves the case of the arthritis drug celecoxib (Celebrex), where the study lasted 12 months but the authors only presented 6 months of data. The second case involves the NIMH Multimodal Treatment Study (MTA) study evaluating the efficacy of stimulant medication for attention-deficit hyperactivity disorder where ratings made by several groups are reported in contradictory fashion. The MTA authors have not clarified the confusion, at least in print, suggesting that the actual findings of the study may have played little role in the authors' reported conclusions.

We compared the systolic blood pressure (SBP)-lowering efficacy and safety of crystalline valsartan/sacubitril (LCZ696, an angiotensin receptor blocker-neprilysin inhibitor) 400 mg daily against valsartan (320 mg once daily) alone or coadministered with placebo or increasing doses of free sacubitril (50, 100, 200, or 400 mg once daily) to identify the optimal antihypertensive combination dose. This multicenter, double-blinded, 7-arm parallel-group study recruited patients with mild-to-moderate systolic hypertension (office SBP 150-179 mm Hg). Primary-dependent variable was change in office SBP from baseline to week 8. At entry (n = 907), mean age was 61.5 years, sitting office BP 160/90.2 mm Hg, and mean 24-hour ambulatory BP 142/82.1 mm Hg; 852 participants completed the study. At week 8, there were greater reductions in sitting office SBP and 24-hour ambulatory SBP with LCZ696 400 mg than with valsartan 320 mg (-5.7 and -3.4 mm Hg, respectively, P sacubitril 200 mg. Effects were similar in those older and younger than 65 years, and active therapies had adverse event rates similar to placebo. We conclude that crystalline valsartan/sacubitril 400 mg daily (1) is superior to valsartan 320 mg daily for lowering SBP, (2) has similar efficacy to the combination of free valsartan 320 mg plus free sacubitril 200 mg, (3) represents the optimal dosage for systolic hypertension in patients of any age, and (4) is safe and well tolerated.

2004-04-01

Full Text Available Abstract Background Heroin is a synthetic opioid with an extensive illicit market leading to large numbers of people becoming addicted. Heroin users often present to community treatment services requesting detoxification and in the UK various agents are used to control symptoms of withdrawal. Dissatisfaction with methadone detoxification 8 has lead to the use of clonidine, lofexidine, buprenorphine and dihydrocodeine; however, there remains limited evaluative research. In Leeds, a city of 700,000 people in the North of England, dihydrocodeine is the detoxification agent of choice. Sublingual buprenorphine, however, is being introduced. The comparative value of these two drugs for helping people successfully and comfortably withdraw from heroin has never been compared in a randomised trial. Additionally, there is a paucity of research evaluating interventions among drug users in the primary care setting. This study seeks to address this by randomising drug users presenting in primary care to receive either dihydrocodeine or buprenorphine. Methods/design The Leeds Evaluation of Efficacy of Detoxification Study (LEEDS project is a pragmatic randomised trial which will compare the open use of buprenorphine with dihydrocodeine for illicit opiate detoxification, in the UK primary care setting. The LEEDS project will involve consenting adults and will be run in specialist general practice surgeries throughout Leeds. The primary outcome will be the results of a urine opiate screening at the end of the detoxification regimen. Adverse effects and limited data to three and six months will be acquired.

Preliminary studies of adaptation of Self- efficacy Scale for Sources of Mathematics

2011-07-01

Full Text Available In the field of educational psychologically the construct of self-efficacy has received special attention. It has been shown that those students who trust in their own abilities get better academic performance. However, few studies analyze the sources of self-efficacy. Self-efficacy believes are developed according to how people interpret information coming from four different sources: experience skills, vicarious learning, social persuasion, and physiological states. Recently, Usher & Pajares (2009 developed an instrument to assess sources of self-efficacy in Math. The goal of the present work was to evaluate psychometric properties of this scale in a local sample of adolescents from 13 to 15 years old. Preliminary results supported the use of this measure as an adequate alternative to assess self-efficacy in Math. However, more studies are needed in order to obtain a measure more contextualized to the educational system of local students.

Ureteric stones greater than 6mm require intervention. Extracorporeal shockwave lithotripsy (ESWL) and ureteroscopy (URS) with intra-corporeal lithotripsy (ICL) are two least invasive therapies. Both show acceptable stone clearance. What should be the first line of treatment in distal ureteric stones. We conducted this study to compare the efficacy of ESWL and pneumatic ICL in order to develop clear cut treatment guidelines. Methods: This randomized control trial was conducted at Institute of Kidney Diseases, Peshawar from June 2011 to June 2012. Two hundred and twenty-four patients with distal ureteric stones 6-12 mm in size were included. Patients were randomized into two groups. Group-A patients were treated with URS plus ICL and Group-B with ESWL. Patients were evaluated for stone clearance after 2 weeks, with X-ray KUB and ultrasound. All the data were recorded in a proforma and analysed in SPSS 10. Fisher's exact test was applied to compare the efficacy and a p-value of 0.05 was considered significant. Results: Out of 112 patients in Group-A, 75 (67%) were males and 37 (33%) were females while in Group-B 79 (70.5%) were males and 33 (29.5%) were females. The mean age in Group-A was, 48.73 ± 16.23 years whereas it was 6 ± 14.58 years in Group-B. Overall, mean age was 47.36 ± 15.4 years. Mean stone size was 9.18 ± 1.6 mm. At follow up (2 weeks post-operative) URS with ICL was successful in 101 (90.2%) patients while ESWL was successful in 75 (67%) patients (p-value=0.0001). Conclusion: Extracorporeal shockwave lithotripsy shows acceptable stone clearance but ureteroscopy with intra-corporeal lithotripsy shows superior results in distal ureteric stones. (author)

Full Text Available Rachel Babij, Jai S Perumal Department of Neurology, Weill Cornell Medical College, New York, NY, USA Abstract: Alemtuzumab is the newest disease-modifying therapy approved for the treatment of relapsing multiple sclerosis. Alemtuzumab is an anti-CD52 targeted antibody that causes lysis of T and B lymphocytes, monocytes, natural killer cells, macrophages, and dendritic cells. Following its administration, a prolonged T-cell lymphopenia results with emergence of a reconstituted immune system that differs in its composition from that pretreatment. In clinical trials, alemtuzumab has shown impressive efficacy with regard to clinical and radiological outcomes in relapsing multiple sclerosis, along with sustained long-term beneficial effects, and it is attractive for its once-yearly administration. Despite this, the occurrence of serious secondary autoimmune disorders, infections, and a potential risk of malignancy necessitates a careful evaluation of risks versus benefits for an individual patient prior to its use. The requirement of patient commitment to the intense mandatory monitoring program is also a factor to be considered when incorporating alemtuzumab into the treatment regimen.

Purpose. To evaluate injection-associated pain, safety, and efficacy with the isotonic contrast medium iodixanol (Visipaque 270 mg I/ml) compared with iopromide (Ultravist 300 mg I/ml) in femoral arteriography. Methods. A multicenter, double-blind, randomized, parallel-group clinical investigation was carried out in 54 hospitals in Europe. Of the patients evaluated, 1225 received iodixanol and 1227 iopromide in conventional and/or digital subtraction angiography. Results. The iodixanol group reported statistically significantly less injection-associated pain (0.9%) than the iopromide group (9.5%) (p<0.001). Further, 4.1% in the iodixanol group experienced pain and/or severe heat sensation vs 19.8% in the iopromide group (p<0.001). In the iodixanol group, 1.8% of the patients experienced contrast-related adverse events vs 2.4% in the iopromide group (p=NS). Overall diagnostic information was optimal for 94.1% in the iodixanol group and 95.3% in the iopromide group (p=NS). Conclusions. Iodixanol 270 mg I/ml causes significantly less injection-associated pain during femoral arteriography and is as safe and efficatious as iopromide 300 mg I/ml

Recently, a new power toothbrush has been marketed with a design that fundamentally differs from other marketed power toothbrushes, in that it incorporates a round oscillating head, in conjunction with fixed bristles. The objective of this study was to compare the plaque removal efficacy of a control manual toothbrush (Colgate Navigator) to this experimental power toothbrush (Crest SpinBrush) following a single use. This study was a randomized, controlled, examiner-blind, 4-period crossover design which examined plaque removal with the two toothbrushes following a single use in 40 completed subjects. Plaque was scored before and after brushing using the Turesky Modification of the Quigley-Hein Index. Baseline plaque scores were 1.77 for both the experimental toothbrush and control toothbrush treatment groups. With respect to all surfaces examined, the experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.48 while the control toothbrush delivered an adjusted mean difference of 0.35. The experimental toothbrush removed, on average, 37.6% more plaque than the control toothbrush. These results were statistically significant (P< 0.001). With respect to buccal surfaces, the experimental toothbrush delivered an adjusted mean difference between baseline and post-brushing plaque scores of 0.54 while the control toothbrush delivered an adjusted mean difference of 0.42. This represents 27.8% more plaque removal with the experimental toothbrush compared to the control toothbrush. These results were also statistically significant (P= 0.001). Results on lingual surfaces also demonstrated statistically significantly (P< 0.001) greater plaque removal for the experimental toothbrush with an average of 53.4% more plaque removal.

This double-blind parallel-design clinical study compared the efficacy of a stabilized stannous fluoride dentifrice (Crest Plus Gum Care), baking soda and peroxide (NaF) dentifrice (Mentadent), and essential oil mouthrinse (Listerine) to a conventional NaF dentifrice (Crest) for the control of plaque, gingivitis and gingival bleeding over six months. Following an initial baseline examination and stratification, subjects received a complete oral prophylaxis and were distributed assigned test products. Following three and six months, subjects re-visited the clinic for examinations. Evaluations at baseline and at 3 and 6 months included soft tissue status. Löe-Silness gingivitis/gingival bleeding, Silness-Löe plaque and dental stain. Results subsequent to six months of product use were as follows: At six months, the stabilized stannous fluoride dentifrice was observed to produce statistically significant 17.5% reductions in gingivitis and 27.5% reductions in gingival bleeding relative to the NaF dentifrice. The combination of sodium fluoride dentifrice and essential oil mouthrinse produced statistically significant reductions of 7.4% in gingivitis and 10.8% in plaque as compared with the NaF dentifrice. The stabilized stannous fluoride dentifrice produced statistically significant reductions in both gingivitis (10.8%) and gingival bleeding (23.0%) relative to the combination of sodium fluoride dentifrice and essential oil mouthrinse. The baking soda and peroxide (NaF) dentifrice did not provide reductions in gingivitis, plaque or gingival bleeding as compared with the conventional NaF dentifrice. The stabilized stannous fluoride dentifrice provided statistically significant reductions in gingivitis as compared with the baking soda and peroxide dentifrice following six months of use, and both the essential oil mouthrinse and stabilized stannous fluoride dentifrice provided statistically significant reductions in gingivitis as compared with the baking soda and

Full Text Available In this single-blind, multiple-dose study the efficacy and tolerability of flurbiprofen was compared with that of piroxicam in 60 adult patients suffering from osteoarthritis of the knee. The patients were randomly allocated to receive either flurbiprofen 100 mg twice daily or piroxicam 20 mg once daily for a period of four weeks. Clinical assessments w.r.t. pain, tenderness, stiffness, swelling and general activity of patient were carried out prior to initiation of trial therapy and thereafter at weekly intervals for four weeks. The findings were graded. Though significant improvements as compared to baseline data occurred in both the treatment groups, flurbiprofen was found to be superior to piroxicam in improving pain on movement and at rest (p < 0.05. The incidence of side effects was less in the group receiving flurbiprofen (6% compared to 47% observed with piroxicam.

A multicentre double-blind randomized study was carried out to compare topical ciprofloxacin and topical gentamicin in the treatment of simple non-cholesteatomatous purulent chronic otitis media. Three hundred and eight patients were included in the study, 159 treated with ciprofloxacin and 149 treated with gentamicin. The percentage of clinical success (elimination of otorrhoea) was 95% with ciprofloxacin and 94% with gentamicin (ns). Likewise, the percentage of bacteriological erradication was 96% with ciprofloxacin and 93% with gentamicin. Both drugs were well tolerated, without changes in the audiometric values. In these patients, topical ciprofloxacin shows the same efficacy as topical gentamicin without any potential ototoxic effect.

To determine whether visual aids help people recall quantitative efficacy information in direct-to-consumer (DTC) prescription drug advertisements, and if so, which types of visual aids are most helpful. Individuals diagnosed with high cholesterol (n=2504) were randomized to view a fictional DTC print or television advertisement with no visual aid or one of four visual aids (pie chart, bar chart, table, or pictograph) depicting drug efficacy. We measured drug efficacy and risk recall, drug perceptions and attitudes, and behavioral intentions. For print advertisements, a bar chart or table, compared with no visual aid, elicited more accurate drug efficacy recall. The bar chart was better at this than the pictograph and the table was better than the pie chart. For television advertisements, any visual aid, compared with no visual aid, elicited more accurate drug efficacy recall. The bar chart was better at this than the pictograph or the table. Visual aids depicting quantitative efficacy information in DTC print and television advertisements increased drug efficacy recall, which may help people make informed decisions about prescription drugs. Adding visual aids to DTC advertising may increase the public's knowledge of how well prescription drugs work. Published by Elsevier Ireland Ltd.

Live-attenuated viruses derived from SIV and SHIV have provided the most consistent protection against challenge with pathogenic viruses, but concerns regarding their long-term safety and efficacy have hampered their clinical usefulness. We report a longitudinal study in which we evaluated the long-term safety and efficacy of ΔvpuSHIV PPC , a live virus vaccine derived from SHIV PPC . Macaques were administered two inoculations of ΔvpuSHIV PPC , three years apart, and followed for eight years. None of the five vaccinated macaques developed an AIDS-like disease from the vaccine. At eight years, macaques were challenged with pathogenic SIV and SHIV. None of the four macaques with detectable cellular-mediated immunity prior to challenge had detectable viral RNA in the plasma. This study demonstrates that multiple inoculations of a live vaccine virus can be used safely and can significantly extend the efficacy of the vaccine, as compared to a single inoculation, which is efficacious for approximately three years

Recent epidemiological developments demonstrated that gene segments of swine influenza A viruses can account for antigenic changes as well as reduced drug susceptibility of pandemic influenza A viruses. This raises questions about the efficacy of preventive measures against swine influenza A viruses. Here, the protective effect of vaccination was compared with that of prophylactic Tamiflu® treatment against two Eurasian swine influenza A viruses. 11-week-old pigs were infected by aerosol nebulisation with high doses of influenza virus A/swine/Potsdam/15/1981 (H1N1/1981, heterologous challenge to H1N1 vaccine strain) and A/swine/Bakum/1832/2000 (H1N2/2000, homologous challenge to H1N2 vaccine strain) in two independent trials. In each trial (i) 10 pigs were vaccinated twice with a trivalent vaccine (RESPIPORC® FLU3; 28 and 7 days before infection), (ii) another 10 pigs received 150 mg/day of Tamiflu® for 5 days starting 12 h before infection, and (iii) 12 virus-infected pigs were left unvaccinated and untreated and served as controls. Both viruses replicated efficiently in porcine respiratory organs causing influenza with fever, dyspnoea, and pneumonia. Tamiflu® treatment as well as vaccination prevented clinical signs and significantly reduced virus shedding. Whereas after homologous challenge with H1N2/2000 no infectious virus in lung and hardly any lung inflammation were detected, the virus titre was not and the lung pathology was only partially reduced in H1N1/1981, heterologous challenged pigs. Tamiflu® application did not affect these study parameters. In conclusion, all tested preventive measures provided protection against disease. Vaccination additionally prevented virus replication and histopathological changes in the lung of homologous challenged pigs. PMID:23630601

The topical application of two different anti-inflammatory extracts incorporated in adhesive transdermal drug delivery systems (TDDSs) was investigated. Therefore, anti-inflammatory properties and percutaneous absorption behavior of adhesive TDDSs were characterized in vitro conducting experiments with a dermatologically relevant human skin model. Anti-inflammatory efficacy against UV irradiation of both TDDSs was determined in vitro with EpiDerm™. The reduction of the release of proinflammatory cytokines by topically applied TDDSs was compared with the reduction during the presence of the specific cyclooxygenase inhibitor diclofenac in the culture medium. A similar anti-inflammatory efficacy of the topically applied TDDSs in comparison with the use of diclofenac in the culture medium should be achieved. Furthermore, percutaneous absorption in efficacy tests was compared with percutaneous absorption in diffusion studies with porcine cadaver skin. Both the topically applied TDDSs showed a significant anti-inflammatory activity. Permeation coefficients through the stratum corneum and the epidermis gained from the release studies on porcine cadaver skin (Magnolia: 2.23·10(-5) cm/h, licorice: 4.68·10(-6) cm/h) were approximately five times lower than the permeation coefficients obtained with the EpiDerm™ skin model (Magnolia: 9.48·10(-5) cm/h, licorice: 24.0·10(-6) cm/h). Therefore, an adjustment of drug doses during experiments with the EpiDerm™ skin model because of weaker skin barrier properties should be considered.

This study compared the therapeutic efficacy of steroidal and non-steroidal agents for treating oral lichen planus. Forty patients with clinical and/or histologically proven oral lichen planus were randomly placed into four groups and treated with topical triamcinolone, oral dapsone, topical tacrolimus or topical retinoid for three months. Pre- and post-treatment symptoms and signs were scored for each patient. Patients in all treatment groups showed significant clinical improvement after three months (p 0.05) and for topical retinoid vs topical tacrolimus (p > 0.05). Non-steroidal drugs such as dapsone, tacrolimus and retinoid are as efficacious as steroidal drugs for treating oral lichen planus, and avoid the side effects associated with steroids.

A number of clinical studies have consistently demonstrated that power toothbrushes deliver superior plaque removal compared to manual toothbrushes. Recently, a new power toothbrush (Crest SpinBrush) has been marketed with a design that fundamentally differs from other marketed power toothbrushes. Other power toothbrushes feature a small, round head designed to oscillate for enhanced cleaning between the teeth and below the gumline. The new power toothbrush incorporates a similar round oscillating head in conjunction with fixed bristles, which allows the user to brush with optimal manual brushing technique. The objective of this randomized, examiner-blind, parallel design study was to compare the plaque removal efficacy of a positive control power toothbrush (Colgate Actibrush) to an experimental toothbrush (Crest SpinBrush) following a single use among 59 subjects. Baseline plaque scores were 1.64 and 1.40 for the experimental toothbrush and control toothbrush treatment groups, respectively. With regard to all surfaces examined, the experimental toothbrush delivered an adjusted (via analysis of covariance) mean difference between baseline and post-brushing plaque scores of 0.47, while the control toothbrush delivered an adjusted mean difference of 0.33. On average, the difference between toothbrushes was statistically significant (p = 0.013). Because the covariate slope for the experimental group was statistically significantly greater (p = 0.001) than the slope for the control group, a separate slope model was used. Further analysis demonstrated that the experimental group had statistically significantly greater plaque removal than the control group for baseline plaque scores above 1.43. With respect to buccal surfaces, using a separate slope analysis of covariance, the experimental toothbrush delivered an adjusted mean difference between baseline and post-brushing plaque scores of 0.61, while the control toothbrush delivered an adjusted mean difference of 0

Context Dental caries continues to affect a significant portion of the world population and treatment of the decay is associated with pain by many patients. Intervention and application of rotary instruments for treatment of carious lesions has often resulted in considerable removal of tooth structure. Chemo-mechanical method, a minimal invasive technique for caries removal was developed to overcome these shortcomings. This innovative method seems to be efficient in removing infected dentine without altering the healthy dental tissue or harming the adjacent oral mucosa. Aim To evaluate the efficacy and efficiency of Caries removal Using Polymer Bur, Stainless Steel Bur, Carisolv and Papacarie. Materials and Methods A total of 120 sectioned specimens were obtained from 60 extracted teeth. Each tooth was sectioned mesiodistally in the center of the carious lesion so that two halves (buccal and lingual or palatal) having equal sized carious lesions are compared. The sectioned specimens were subdivided into four groups (Polymer Bur, Stainless Steel Bur, Carisolv, Papacarie) allotting 30 specimens to each for caries excavation. Results One-way ANOVA, Chi-square test analysis was done for comparison between groups which showed significant results with Stainless Steel Bur excavation taking less mean time when compared to other agents and Polymer Bur showed more amount of bacterial remnants after excavation whereas Carisolv and Papacarie were efficient with less dentinal tubule destruction and bacterial remnants after excavation. Further inter comparison between groups was done using Paired t-test and Fischer’s Exact-test. Conclusion The Mean time taken by Stainless Steel Bur excavation was found to be less and caused more amount of dentinal tubule destruction when compared to Polymer Bur, Carisolv and Papacarie. Chemo-mechanical methods found to be more efficient with lesser amount of bacterial remnants and dentinal tubule destruction after caries excavation when

Topical Acyclovir has moderate efficacy on recurrent HSV symptoms, requiring repeat applications for several days. Topical Dynamiclear, which requires only a single dose application, may provide a more effective and convenient treatment option for symptomatic management of HSV. The study assessed the comparative efficacy and tolerability of a single use, topical formulation containing copper sulfate pentahydrate and Hypericum perforatum that is marketed as Dynamiclear™ to a topical 5% Acyclovir cream standard preparation and use. A prospective, randomized, multi-centered, comparative, open-label clinical study was conducted. A total of 149 participants between 18 and 55 years of age with active HSV-1 and HSV-2 lesions were recruited for the 14-day clinical trial. Participants were randomized into two groups: A (n=61), those receiving the Dynamiclear formulation, and B (n=59), those receiving 5% Acyclovir. Efficacy parameters were assessed via physical examination at baseline (day 1), day 2, 3, 8, and 14. Laboratory safety tests were conducted at baseline and on day 14. Use of the Dynamiclear formulation was found to have no significant adverse effects and was well tolerated by participants. All hematological and biochemical markers were within normal range for the Dynamiclear group. Statistically, odds for being affected by burning and stinging sensation were 1.9 times greater in the Acyclovir group in comparison to the Dynamiclear group. Similarly, the odds of being affected by symptoms of acute pain, erythema and vesiculation were 1.8, 2.4, and 4.4 times higher in the Acyclovir group in comparison to the Dynamiclear group. The Dynamiclear formulation was well tolerated, and efficacy was demonstrated in a number of measured parameters, which are helpful in the symptomatic management of HSV-1 and HSV-2 lesions in adult patients. Remarkably, the effects seen from this product came from a single application.

Aims: This study compared the psychometric properties of two self-efficacy instruments related to physical activity. Factorial validity, cross-group and longitudinal invariance, and composite reliability were examined. Methods: Secondary analysis was conducted on data from a group randomized controlled trial investigating the effect of a 17-week intervention on increasing moderate to vigorous physical activity among 5th–8th grade girls (N = 1,012). Participants completed a 6-item Physical Activity Self-Efficacy Scale (PASE) and a 7-item Self-Efficacy for Exercise Behaviors Scale (SEEB) at baseline and post-intervention. Confirmatory factor analyses for intervention and control groups were conducted with Mplus Version 7.4 using robust weighted least squares estimation. Model fit was evaluated with the chi-square index, comparative fit index, and root mean square error of approximation. Composite reliability for latent factors with ordinal indicators was computed from Mplus output using SAS 9.3. Results: Mean age of the girls was 12.2 years (SD = 0.96). One-third of the girls were obese. Girls represented a diverse sample with over 50% indicating black race and an additional 19% identifying as mixed or other race. Both instruments demonstrated configural invariance for simultaneous analysis of cross-group and longitudinal invariance based on alternative fit indices. However, simultaneous metric invariance was not met for the PASE or the SEEB instruments. Partial metric invariance for the simultaneous analysis was achieved for the PASE with one factor loading identified as non-invariant. Partial metric invariance was not met for the SEEB. Longitudinal scalar invariance was achieved for both instruments in the control group but not the intervention group. Composite reliability for the PASE ranged from 0.772 to 0.842. Reliability for the SEEB ranged from 0.719 to 0.800 indicating higher reliability for the PASE. Reliability was more stable over time in the control

The objective of this study is to compare the efficacy of mature mud pack and hot pack therapies on patients with knee osteoarthritis. This study was designed as a prospective, randomized-controlled, and single-blinded clinical trial. Twenty-seven patients with clinical and radiologic evidence of knee osteoarthritis were randomly assigned into two groups and were treated with mature mud packs (n 15) or hot packs (n=12). Patients were evaluated for pain [based on the visual analog scale (VAS)], function (WOMAC, 6 min walking distance), quality of life [Short Form-36 (SF-36)], and serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and insulin-like growth factor-1 (IGF-1) at baseline, post-treatment, and 3 and 6~months after treatment. The mud pack group shows a significant improvement in VAS, pain, stifness, and physical function domains of WOMAC. The difference between groups of pain and physical activity domains is significant at post-treatment in favor of mud pack. For a 6 min walking distance, mud pack shows significant improvement, and the difference is significant between groups in favor of mud pack at post-treatment and 3 and 6 months after treatment. Mud pack shows significant improvement in the pain subscale of SF-36 at the third month continuing until the sixth month after the treatment. Significant improvements are found for the social function, vitality/energy, physical role disability, and general health subscales of SF-36 in favor of the mud pack compared with the hot pack group at post-treatment. A significant increase is detected for IGF-1 in the mud pack group 3 months after treatment compared with the baseline, and the difference is significant between groups 3 months after the treatment. Mud pack is a favorable option compared with hotpack for pain relief and for the improvement of functional conditions in treating patients with knee osteoarthritis.

As with other forms of violent behaviour, bullying is the result of multiple influences acting on different societal levels. Yet the majority of studies on bullying focus primarily on the characteristics of individual bullies and bullied. Fewer studies have explored how the characteristics of central contexts in young people’s lives are related to bullying behaviour over and above the influence of individual-level characteristics. This study explores how teacher-rated school collective efficacy is related to student-reported bullying behaviour (traditional and cyberbullying victimization and perpetration). A central focus is to explore if school collective efficacy is related similarly to both traditional bullying and cyberbullying. Analyses are based on combined information from two independent data collections conducted in 2016 among 11th grade students (n = 6067) and teachers (n = 1251) in 58 upper secondary schools in Stockholm. The statistical method used is multilevel modelling, estimating two-level binary logistic regression models. The results demonstrate statistically significant between-school differences in all outcomes, except traditional bullying perpetration. Strong school collective efficacy is related to less traditional bullying perpetration and less cyberbullying victimization and perpetration, indicating that collective norm regulation and school social cohesion may contribute to reducing the occurrence of bullying.

Full Text Available The purpose of this study is to develop a valid and reliable measurement tool determining teachers’ self-efficacy regarding rubrics. Especially in educational environments, rubrics are measurement tools used in the assessment phase of student products usually based on higher-order thinking skills. Determination of teachers’ self-efficacy regarding rubrics can give researchers an idea on how often and how accurately teachers use such tools.  For this reason, the existence of a tool accurately measuring self-efficacy variable is necessary. This study’s sample consists of 641 elementary, middle and high school teachers. To determine teachers’ self-efficacy levels regarding rubrics, 47-item draft was developed. As a result of validity and reliability analyzes, a 28-item measurement tool with a four-factor structure was obtained. The total scale’s and sub-factors’ internal consistency is quite high. Using this scale, researchers can examine the relationships between teachers’ self-efficacy and various variables that play an important role in education. In addition, comparative studies on the intended use of rubrics can be conducted by determining teachers’ self-efficacy levels regarding rubrics.

Comparative study was conducted to determine the efficacy of polyphenol oxidase inhibitors to control browning in guava juice/concentrates parallel to sulfite. Although sulfites are highly effective to control the browning but these have shown adverse effect on health particularly to those who have pulmonary disorder like asthma. Filtration with useful filter aid and juicing agents are found to be helpful in removing browning residue particulates fractions to extend the shelf life of the juice. Non-enzymatic browning can be prevented by cold blanching. (author)

Objective: To compare the interventional therapeutic efficacy of methotrexate (MTX) with that of 5-fluorouracil (5-FU) in treating uterine incisional pregnancy after cesarean section. Methods: A total of 92 patients with uterine incisional pregnancy after cesarean section, who were admitted to the hospital during the period from 2007 to 2010, were randomly divided into two groups: group MTX and group 5-FU. Patients in group MTX (n=46) received intra-arterial infusion of MTX (60-200) mg, which was followed by arterial embolization. Patients in group 5-FU (n=46) received intra-arterial infusion of 5-FU (1000-1250) mg, which was followed by arterial embolization. After the treatment the serum β-HCG and progesterone levels were determined daily for three succeeding days. The patients were followed up for three months. The clinical results were compared between the two groups. Results: The cure rates in group MTX and group 5-FU were 97.2% and 100%, respectively. No significant difference in cure rate existed between the two groups (P>0.05). A rapid fall in the serum β-HCG and progesterone levels within 1-3 days after the treatment were detected in 40 cases of group MTX and 38 cases of group 5-FU, and the decreasing extent was over 50%-80%, but the difference between the two groups was not significant (P>0.05). At the operation day, all patients of both groups had abdominal pain, and three patients in group MTX and 2 patients in 5-FU group had nausea and vomiting, but the difference between the two groups was not significant (P>0.05). During the follow-up period, no significant difference in the recovery time of the mental cycle and the hormone levels were found between the two groups (P>0.05). Conclusion: For the interventional treatment of uterine incisional pregnancy after cesarean section, the use of MTX has the same clinical efficacy as the use of 5-FU does. (authors)

Several Erythropoiesis-stimulating agents (ESAs) are available to treat anemia in patients with chronic kidney disease (CKD). Questions about the comparability of such therapeutic options are not purely a regulatory or economical matter. Appropriate use of originator or biosimilar in these patients need to be supported by clinical data. Regarding the prevention of blood transfusion, reduction of fatigue, breathlessness and mortality or cardiovascular events, a summary of the comparative efficacy and safety data of these drugs is lacking. We performed a systematic literature search of CENTRAL, PubMed, and Embase through November 11, 2015. Our inclusion criteria encompassed randomized, controlled clinical trials that evaluated the comparative effectiveness of different ESAs originators and/or biosimilar. The considered participants were adults aged 18 years or older with anemia due to CKD. The overall quality of evidence was assessed using the GRADE system. We identified 30 eligible studies including 7843 patients with CKD, and 21/30 studies included patients using hemodialysis or peritoneal dialysis. Compared with ESA biosimilars, epoetin α did not statistically differ for any of the ten measured outcomes. The quality of evidence varied from low to very low. In the comparison between epoetin α vs. darbepoetin α, no differences were observed for all outcomes, but blood transfusions showed favorable results for darbepoetin α: RR 2.18 (1.31-3.62). The quality of evidence varied from low to very low. No differences were observed between epoetin β and methoxy polyethylene glycol-epoetin β, and between darbepoetin α and methoxy polyethylene glycol-epoetin β, the quality of evidence varied from moderate to very low. Data from 31 included studies allowed to pool data in meta-analysis related to four different comparisons and eleven outcome measures. Nevertheless, only one result was statistically significant in favor of darbepoetin α in the comparison with epoetin

Haemonchosis caused by Haemonchus contortus causes great economic losses in terms of weight loss, poor quality meat and loss of wool in sheep and goats. Therapeutical trials were conducted by using various allopathic, homeopathic, herbal and biological products. For this purpose total of 120 sheep and goats were randomly divided into groups A, B, C, D, E and F and animals in group A, B, C and D were treated with Ivermectin, Azedarachta indica (neem Leaves) Powder, Trematox (a homeopathic drug), EM-Biovet (Effective micro-organisms) respectively. Whereas E and F were kept as infected untreated and control respectively. Efficacy of drugs was measured based on reduction in EPG count, it was found that ivermectin at recommended dose rate is found more effective; Azedarachta Indica (Neem) found second and Trematox third drug of choice in combating the infection against haemonchosis, whereas EM Biovet was inferior to other drugs. In these studies it was found that Azedarachta Indica (Neem) is cheapest and easily available drug than others. Comparison based on reduction in EPG count indicated that Azedarachta indica and Trematox were fairly affective in combating haemonchosis but EM Bio-vet fail to cure all cases of haemonchosis. It was also noted that all drugs were more affective at two-dose level as compared to one dose level. Ivermectin proved to be best drug against haemonchosis. Efficacy of Azedarachta indica (neem) found to be closer to Ivermectin and EM Bio-vet was inferior as compared to Ivermectin. (author)

To compare the longer-term clinical efficacy of two occlusion-technology toothpastes - a 5% calcium sodium phosphosilicate (CSPS) toothpaste and a commercially available 8% arginine/calcium carbonate toothpaste - in relieving dentine hypersensitivity (DH). Efficacy was also compared with that of a regular fluoride toothpaste control. This was an exploratory, randomised, examiner-blind, parallel-group, 11-week, controlled study in healthy adults with self-reported and clinically diagnosed DH. After an acclimatisation period, subjects were randomised to one of three study treatments with which they brushed their teeth twice daily. Sensitivity was assessed at baseline and after 1, 2, 4, 6 and 11 weeks treatment in response to evaporative (air) and tactile stimuli (measured by the Schiff Sensitivity Scale/visual analogue scale and tactile threshold, respectively). A total of 135 subjects were randomised to treatment. The two occlusion-technology toothpastes performed similarly over the 11-week treatment period. All study treatments showed statistically significant reductions from baseline in DH at all timepoints for all measures (pcarbonate anti-sensitivity toothpaste provided similar benefits. Improvements in DH continued throughout the 11-week study. Dentine hypersensitivity (DH) is a common and painful condition. Twice-daily use of a 5% calcium sodium phosphosilicate toothpaste reduces DH within 1-2 weeks of initiating use. Ongoing, twice daily use of the sensitivity toothpastes evaluated in this study was associated with continued, clinically significant improvements in DH. Copyright © 2017 The Authors.

Therapies of functional dyspepsia (FD) are limited. DA-9701 is a novel prokinetic agent formulated with Pharbitis semen and Corydalis Tuber. We aimed to assess the efficacy of DA-9701 compared with itopride in FD patients. Patients with FD randomly received either itopride 50 mg or DA-9701 30 mg t.i.d after a 2-week baseline period. After 4 weeks of treatment, 2 primary efficacy endpoints were analyzed: the change from baseline in composite score of the 8 dyspep-tic symptoms and the overall treatment effect. Impact on patients' quality of life was assessed using the Nepean Dyspepsia Index (NDI) questionnaire. We randomly assigned 464 patients with 455 having outcome data. The difference of the composite score change of the 8 symptoms between the 2 groups was 0.62, indicating that DA-9701 was not inferior to itopride. The overall treatment effect response rate was not different between the groups. When responder was defined as ≥ 5 of the 7 Likert scale, responder rates were 37% of DA-9701 and 36% of itopride group. Patients receiving DA-9701 experienced similar mean percentage of days with adequate relief during the 4-week treatment period compared with those receiving itopride (56.8% vs 59.1%). Both drugs increased the NDI score of 5 domains without any difference in change of the NDI score between the groups. The safety profile of both drugs was comparable. DA-9701 significantly improves symptoms in patients with FD. DA-9701 showed non-inferior efficacy to itopride with com-parable safety.

During the first phases of adolescent development, young people have little self-efficacy and resistance against substance use. The aim of this study was to demonstrate the effectiveness of role-playing scenarios on the self-efficacy of students in resisting substance use. A pre test and post test study design was used with a single group. The study was carried out with 245 secondary school students. The scenario-based training, developed by the researchers, was presented by the school counselors once a week for 4 weeks. For this purpose, a booklet of scenarios was prepared for the teachers. The role-playing scenarios were intended to improve adolescents' abilities to say "no" to substance offers, to prevent them from becoming addicted to certain substances, and to call for help if needed. The data of the study were collected using the Personal Information Form and the Self-Efficacy for Adolescences Protecting Substance Abuse Scale . The obtained data were assessed using percentages, chi-square, t test, and F test in the SPSS software. Results showed that, after the training, the mean score in the Self-Efficacy for Adolescences Protecting Substance Abuse Scale increased significantly (103.20 ± 20.00) compared with before the training (92.11 ± 17.08) ( P < .05). Short-term outcomes of the class-based scenario training were observed to be effective in the development of students' self-efficacy to resist the temptations of substance use.

Full Text Available BACKGROUND The incidence and morbidity of bacterial vaginosis is high. But most of the patients are asymptomatic and recurrences are common even after effective treatment. Studies comparing the therapeutic efficacy of the drugs indicated for Bacterial vaginosis are also very minimal. Aim of this study was to analyse the epidemiological pattern of bacterial vaginosis and to compare the efficacy of Metronidazole and Lactobacillus in the management of bacterial vaginosis. MATERIALS AND METHODS 100 newly diagnosed Bacterial vaginosis patients were enrolled and randomly allotted into two study groups of Metronidazole for one week and Lactobacillus for two months respectively. The patients are followed up based on Amsel’s criteria and Nugent’s scoring system at the time of initiation of treatment, one week, one month, two months and six months after treatment. Ultrasonogram was done at the end of two months. Statistical Analysis- chi square test with yate’s correction and Fisher’s exact test (2 tailed to calculate the P value. Settings and Design- Prospective, open labeled, comparative clinical trial. RESULTS Lactobacillus group was better than Metronidazole based on Amsel’s criteria at six months follow up period and based on Nugent’s scoring system at two months and six months follow up period. CONCLUSION Epidemiological interpretation in our study shows Bacterial vaginosis is common in the 24-40 years of age; marital status, earlier age at marriage, number of deliveries is directly proportionate to bacterial vaginosis incidence. Irregular menstrual cycle, number of sexual partners, and mode of delivery has no association with the incidence of Bacterial vaginosis. Moderate to profuse genital discharge is the commonest symptom observed. Whiff test (80%, Clue cells (90% and alkaline vaginal pH > 5 has high degree of sensitivity.

A field experiment was carried out to study the efficacy of different post-emergence herbicides for controlling weeds in wheat during a Rabi season 2008-09. Experiment comprised of six treatments, i.e. weed-infested control, pyroxasulfone at 50 g a.i ha/sup -1/, metribuzin at 250 g a.i ha/sup -1/, isoproturon at 1080 g a.i ha/sup -1/, clodinafop propargyl at 240 g a.i ha/sup -1/ and as post-emergence herbicides. Results revealed that Post-emergence application of bromoxynil + MCPA at 247+247 g a.i ha/sup -1/ isoproturon (1080 g a.i ha) proved to be best for obtaining maximum grain plus straw yield up to the level of weed-free -1 -1 control. Bromoxynil + MCPA (247+247 g a.i ha) and clodinafop propargyl (240 g a.i ha/sup -1/) also gave maximum spike bearing tillers, number of grains spike and 1000-grain weight. Isoproturon (1080 g a.i ha/sup -1/) strictly reduced the weeds population as well as biomass as compared to weed-infested control. Poor weed control was achieved by using pyroxasulfone and metribuzin treatments. Hence, post-emergence Isoproturon (1080 g a.i ha/sup -1/) followed by bromoxynil + MCPA (247+247 g a.i ha/sup -1/ ) was provide to be the most effective herbicide against weeds and resulted in maximum wheat yield.

To compare the clinical efficacy and safety of nemonoxacin with levofloxacin in treating community-acquired pneumonia (CAP) in a Phase II clinical trial. One hundred ninety-two patients with CAP were randomized to receive oral nemonoxacin (500 mg or 750 mg) or levofloxacin (500 mg) once daily for 7-10 days. Clinical and bacteriological responses were determined at the test of cure (TOC) visit in the full analysis set (FAS). The clinical cure rate of nemonoxacin (500 mg), nemonoxacin (750 mg), and levofloxacin (500 mg) was 93.3%, 87.3%, and 88.5%, respectively, in the FAS (n = 168), and 93.0%, 93.9%, and 88.9%, respectively in the per protocol set (n = 152). At the TOC visit, nemonoxacin at 500 mg and 750 mg was proven to be noninferior to levofloxacin at 500 mg in the FAS in terms of clinical efficacy. The overall bacteriological success rate was 83.3% in both nemonoxacin groups and 80.0% in the levofloxacin 500 mg group in the bacteriological FAS. The comprehensive efficacy rate was comparable among the three groups (87.5% for the nemonoxacin 500 mg group, 93.8% for the nemonoxacin 750 mg group, and 81.3% for the levofloxacin 500 mg group). Most drug-related adverse events were mild and transient, mainly gastrointestinal symptoms such as nausea and vomiting, transient neutropenia, and elevated liver enzymes. No drug-related serious adverse events occurred. Either 500 mg or 750 mg of oral nemonoxacin taken once daily for 7-10 days demonstrated high clinical and bacteriological success rates in Chinese adult patients with CAP. Nemonoxacin at 500 mg once daily for 7-10 days is recommended for future Phase III clinical trials. ClinicalTrials.gov identifier: NCT01537250. Copyright © 2015. Published by Elsevier B.V.

Full Text Available Introduction: The objective of the present study is to compare the respiratory function and pain relief of two parenteral analgesics tramadol and morphine under clinical conditions. Materials and Methods: The trial was conducted as an open label-randomized, single center study. The study was performed during 3 months in 1999. In total, 64 patients were enrolled in Shariatie University Hospital, while the other 32 patients were treated with morphine. Results: There were 12 male and 20 female in either groups. The mean age was 48±15 in tramadol versus 43±16 morphine group. Concerning the amount of the medication given to the patients. It would be observed that tramadol patients received 194±72 mg and morphine patients 17±7 mg out of drugs. At study admission vital signs were recorded. The pulse rate, blood pressure and respiratory rate are presented revealing no obvious differences between the treatment groups. There was a broad range regarding the underlying type of operation, however, a laparatomy or a cholecystectomy was performed in 24 (75.0% Vs. 26 (81.3% patients, respectively. All 64 patients were receiving anaesthetics as stipulated in the protocol. Of them being diazepam, sufentanil, succinylcholine chloride and thiopental as the most frequent reported, 4 Vs. 3 patient were given additional fentanylin a mean dosage of 220 mg Vs. 83 mcg. The oxygen saturation was the main safety parameter of the present study. No obvious differences between the two treatment groups can be detected (P<0.472. Primary efficacy end point was the pain assessment. The pain intensity at each scheduled time point was recorded. At study inclusion no differences between the treatment groups uncured, but during the 24 hour observation period the tramadol patients were in advantage (P<0.001. Conclusion: This study shows that long-term efficacy of tramadol is better than morphine.

To compare tulobuterol patch and oral salbutamol sulfate in terms of efficacy and safety in children with mild or moderate acute attack of bronchial asthma. A total of 92 children with mild and moderate acute asthmatic attack were randomly divided into salbutamol group (n=46) and tulobuterol group (n=46). Both groups received routine treatment with antihistamine, selective leukotriene receptor antagonist and glucocorticoid. In addition, the salbutamol group was given slow-release capsules of salbutamol sulfate, and the tulobuterol group was treated with tulobuterol patch. The two groups were compared with respect to symptom scores of cough, wheeze, respiratory rate, wheezing sound, three depression sign and peak expiratory flow, as well as adverse events. As the treatment proceeded, symptom scores decreased in both groups; on the third day of treatment, all symptom scores except cough score showed a significant decrease in both groups (Pattack.

Hormonal role is shown to exist in pathogenesis of the melasma, and sex-hormone related drugs may have an effect on melasma.Aim: To investigate efficacy of 1% flutamide cream versus 4% hydroquinone cream on melasma.Methods: In a parallel randomized clinical trial, 74 women with melasma were allocated to receive a sunscreen along with 4% hydroquinone cream or 1% flutamide cream. Melasma Area and Severity Index (MASI, mexameter melanin assay, and patient satisfaction were investigated.Results: Mean age of the participants was 33.8 years. Mean length of time suffering from Melasma was 96.3 months. The subjects reported in average 1.1 hours per day of exposure to sunlight. Mean standardized total patient satisfaction score was 28.8 (standard deviation [SD] 17.2 in flutamide group patients versus 18 (SD 15.5 in control group (P<0.01. Regardless of treatment group, the skin darkness assessed upon MASI scales was reduced over the treatment course (P<0.001. Using mixed effects, longitudinal modeling showed better treatment efficacy based on MASI scale for flutamide group compared to the hydroquinone group (P<0.05. However, longitudinal analysis of mexameter scores did not reveal any significant difference in melanin measurements between flutamide and hydroquinone.Conclusion: Topical flutamide appeared as effective as topical hydroquinone in treating melasma using mexameter assessment but with a better MASI improvement trend and higher patient satisfaction in flutamide treatment versus topical hydroquinone.

Introduction: This study was aimed to compare the efficacy and side effects of memantine, an antagonist of the NMDA receptor of glutamate, with risperidone given the fact that glutamate has been noted for its possible effects in the pathogenesis of autism. Risperidone, an atypical antipsychotic, has been approved by FDA for the management of irritability associated with autism. Methods: 30 children, aged 4-17 years, entered an 8-week, randomized trial. Patients were randomly assigned to receive either risperidone or memantine. Autism Behavior Checklist (ABC), Childhood Autism Rating Scale (CARS), Clinical Global Impressions - Improvement (CGI-I) and Clinical Global Impression-Severity (CGI-S) scales were used to assess behavioral symptoms of the patients. Results: Both risperidone and memantine reduced the scores of 4 subscales of ABC as well as the 10-item and the total score of CARS significantly. However, differences between the 2 drugs in the scores of each evaluating scale were not found to be significant. Relatively, larger number of patients on risperidone showed "very much improvement" when assessed by CGI-I scale when compared with those on memantine. Discussion and conclusion: The present study suggests that memantine may have beneficial effects in the treatment of many core symptoms of autism. Therefore, memantine may be considered as a potential medication in the treatment of those autistic children who do not respond or cannot tolerate side effects of risperidone. © Georg Thieme Verlag KG Stuttgart · New York.

Public security, traffic management, and service for the people are the 3 major functions of policing in Taiwan. This definition encompasses not only the traditional job characteristics, but also the level of contextual characteristics and social characteristics because of police work's characteristics and its frequent interaction with the public. Thus, the present study conducted a multilevel model analysis by taking self-efficacy and collective efficacy as the mediating variables. The purpose was to investigate the influences of motivational work characteristics (knowledge-oriented) and social work characteristics (socially and contextually oriented) of work-design model on the police officers' organizational citizenship behavior (OCB), by using first-line police officers in Taiwan as the research objects. The study showed not only that knowledge characteristics will influence the self-efficacy of a police officer and that self-efficacy can in turn influence individual police officers' OCB, but also the contextual effect of social characteristics, contextual characteristics, and collective efficacy on self-efficacy and individuals' OCB. Additionally, there was a crosslevel moderating effect from contextual characteristics on the relationship between knowledge characteristics and self-efficacy and the relationship between self-efficacy and the individuals' OCB. The authors conclude the article with research implications.

Self-efficacy may be an important factor in individuals' recovery from posttraumatic stress reactions after a natural disaster. However, few longitudinal studies have investigated whether self-efficacy predicts the course of posttraumatic recovery beyond lower initial levels of distress. The purpose of the present study was to investigate whether general self-efficacy is related to recovery from posttraumatic stress reactions from a longitudinal perspective. A total of 617 Norwegians exposed to the 2004 Southeast Asian tsunami completed self-report questionnaires measuring their level of disaster exposure and general self-efficacy at 6 months and posttraumatic stress reactions 6 months and 2 years post-disaster. Predictors of changes in posttraumatic stress reactions were analyzed with multivariate mixed effects models. Self-efficacy at 6 months post-disaster was unrelated to trauma exposure and inversely related to posttraumatic stress reactions at 6 months and 2 years post-disaster. However, self-efficacy was not related to recovery from posttraumatic stress reactions between 6 months and 2 years post-disaster. In conclusion, general self-efficacy is related to lower levels of posttraumatic stress reactions in the first months after a disaster but does not appear to be related to improved recovery rates over the longer term.

Full Text Available Introduction: Developing countries contribute to major number of patients living with epilepsy, around five million people are living with epilepsy in India alone. Most of the epileptic children may require multiple antiepileptic therapy due to the failure of monotherapy. Basic research evidence suggest that sodium valproate and carbamazepine (CBZ may have synergistic anticonvulsant effects when they are used together. In addition to that, chronic disorders make the patients economically weak and produce more burden. Aim and Objective: Therefore, this study was designed to compare the efficacy of valproate monotherapy with valproate and CBZ dual therapy. Methodology: It is a prospective, comparative study conducted at a secondary care referral hospital and private clinic. A nonprobabilistic convenient sampling was done to recruit the study subjects. A total of fifty subjects were recruited into the present study, and they were divided into two groups, i.e., monotherapy group (CBZ and dual therapy group (CBZ and valproate. After providing appropriate counseling, subjects were interviewed to estimate the quality of life (QOL using child version of TNO-AZL Children's Quality of Life questionnaire. Hospital patient records, prescription data from the pharmacy were also used to obtain the direct and indirect cost of treatment. Results: Our study results showed that monotherapy has a potential to produce a higher level of QOL than dual therapy. It also involved with decreased seizure frequency. Although there was no statistically significant difference in terms of cost for both the treatment groups, still dual therapy is associated with higher cost burden. The average costs per QOL and changes in the frequency of seizure are also identified to produce higher economic burden to the patients.Conclusion: Thus, the present study has concluded that monotherapy may be considered as better cost-effective treatment in partial seizures than dual therapy

The objective of this review is to identify, summarize, and evaluate clinical trials to determine the efficacy of curcuma in the treatment of osteoarthritis. A literature search for interventional studies assessing efficacy of curcuma was performed, resulting in 8 clinical trials. Studies have investigated the effect of curcuma on pain, stiffness, and functionality in patients with knee osteoarthritis. Curcuma-containing products consistently demonstrated statistically significant improvement in osteoarthritis-related endpoints compared with placebo, with one exception. When compared with active control, curcuma-containing products were similar to nonsteroidal anti-inflammatory drugs, and potentially to glucosamine. While statistical significant differences in outcomes were reported in a majority of studies, the small magnitude of effect and presence of major study limitations hinder application of these results. Further rigorous studies are needed prior to recommending curcuma as an effective alternative therapy for knee osteoarthritis. © The Author(s) 2016.

Intraosseous access is recommended in vitally compromised patients if an intravenous access cannot be easily obtained. Intraosseous infusion can be initiated by various healthcare providers. Currently, there are two mechanical intraosseous devices approved by the U.S. Food and Drug Administration (FDA) for use in adults and children. A comparison is made in this study of the theoretical and practical performance by anesthesiologists and registered nurses of anesthesia (RNAs) in the use of the battery-powered device (device A) versus the spring-loaded needle device (device B). This study entailed a 12-month follow-up of knowledge, skill retention, and self-efficacy measured by standardized testing. A prospective randomized trial was performed, initially comparing 15 anesthesiologists and 15 RNAs, both on using the two types of intraosseous devices. A structured lecture and skill station was given with the educational aids provided by the respective manufacturers. Individual knowledge and practical skills were tested at 0, 3, and 12 months after the initial course. There was no statistical significant difference in the retention of theoretical knowledge between RNAs and anesthesiologists on all testing occasions. However, the self-efficacy of the anesthesiologists is significantly higher (p intraosseous access has been disproven, as anesthesiologists were as successful as RNAs. However, the low self-efficacy of RNAs in the use of intraosseous devices could diminish the chance of them actually using one.

The purpose of this study was to investigate the effect of four commercially available denture adhesives on the incisal and premolar dislodgement forces of maxillary complete dentures by using an electronic and disposable gnathodynamometer and compare the measured incisal forces for differences. This study was conducted with 12 complete maxillary denture wearers. Four commercially available denture adhesives Super Corega(®), Corega Ultra(®), Super Corega Powder(®) and Fittydent Cationic(®) were investigated. Testing protocol and sequence included baseline measurements without adhesives (control) for previous and new dentures and then replications of measurements with the four adhesives. Maximum dislodgement forces were recorded in two sites between central incisors and the left 2nd premolars by using an electronic and disposable gnathodynamometer. To estimate the effect of the different adhesives on the dislodgement forces, data were analyzed by a 2- and 3-way ANOVA, while for estimating the agreement of the two devices a Bland-Altman and Mountain plots were used. ANOVAs indicated significant differences between adhesives (p adhesives increase the denture dislodgement forces, but with differences among them. The two devices do not highly agree with each other, but each one alone is useful in estimating dislodgement forces in clinical practice and research.

2013-01-01

Full Text Available Abstract Background Diabetic foot ulcers (DFUs represent a significant source of morbidity and an enormous financial burden. Standard care for DFUs involves systemic glucose control, ensuring adequate perfusion, debridement of nonviable tissue, off-loading, control of infection, local wound care and patient education, all administered by a multidisciplinary team. Unfortunately, even with the best standard of care (SOC available, only 24% or 30% of DFUs will heal at weeks 12 or 20, respectively. The extracellular matrix (ECM in DFUs is abnormal and its impairment has been proposed as a key target for new therapeutic devices. These devices intend to replace the aberrant ECM by implanting a matrix, either devoid of cells or enhanced with fibroblasts, keratinocytes or both as well as various growth factors. These new bioengineered skin substitutes are proposed to encourage angiogenesis and in-growth of new tissue, and to utilize living cells to generate cytokines needed for wound repair. To date, the efficacy of bioengineered ECM containing live cellular elements for improving healing above that of a SOC control group has not been compared with the efficacy of an ECM devoid of cells relative to the same SOC. Our hypothesis is that there is no difference in the improved healing effected by either of these two product types relative to SOC. Methods/Design To test this hypothesis we propose a randomized, single-blind, clinical trial with three arms: SOC, SOC plus Dermagraft® (bioengineered ECM containing living fibroblasts and SOC plus Oasis® (ECM devoid of living cells in patients with nonhealing DFUs. The primary outcome is the percentage of subjects that achieved complete wound closure by week 12. Discussion If our hypothesis is correct, then immense cost savings could be realized by using the orders-of-magnitude less expensive acellular ECM device without compromising patient health outcomes. The article describes the protocol proposed to test

Objective: To compare antibiotic therapy and appendectomy in uncomplicated acute appendicitis in terms of efficacy. Study Design: Randomized controlled trial. Place and Duration of Study: Surgical Ward Forward Treatment Centre (FTC), 5 Mountain Medical Battalion Forward Kahuta Azad Jammu Kashmir (AJK), from Oct 2011 to Mar 2013. Material and Methods: A total of 103 patients with clinical diagnosis of acute appendicitis (AA) were admitted during the duration of study and divided into two groups by consecutive sampling. The antibiotic group consisted of 51 patients who received intravenous antibiotics for 48 hours and oral antibiotics for another 8 days. The appendectomy group comprised of 52 patients who all underwent standard appendectomy. All the patients were followed up at 1 month and 1 year for assessing efficacy and post treatment complications. Results: The efficacy of antibiotic treatment is 90.625 percent as compared to appendectomy which was 88.46 percent (p=0.759) at 1 month follow up after treatment. At one year post treatment, the comparison between the efficacy of antibiotic therapy (71.87 percent) and appendectomy (87.14 percent) remains statistically insignificant (p=0.055). Conclusion: Antibiotic therapy is comparable to appendectomy in AA in terms of efficacy at 1 month and 1 year post treatment. (author)

In the present study chitin nanogel loaded with anti-psoriatic drug clobetasol was developed (CLCNG) for its topical delivery in psoriasis. CLCNG had the particle size of 132±14nm, with gel like consistency, stability in refrigerator, having higher drug release properties at acidic pH. CLCNG exhibited significant toxicity towards HaCaT and THP-1cell lines by MTT assay. The uptake of nanogel by HaCaT cell lines was confirmed by fluorescent microscopy. CLCNG at 0.35mg/ml exhibited significant anti-inflammatory activity with an average of 65% and 70% inhibition in COX and LOX activities expressed in THP-1 cells. In vitro skin permeation studies revealed the increased transdermal flux with fragmented stratum corneum and loosened epidermal layers in CLCNG treated samples, compared with control drug solution. The in vivo anti-psoriatic studies done on imiquimod model confirmed the potential benefits of the nanogel for the topical delivery of clobetasol in psoriasis. Copyright © 2016 Elsevier B.V.

McMullan, Alexandra; Kelly-Campbell, Rebecca J; Wise, Kim

2018-03-08

This pilot study aimed to investigate whether revising a hearing aid user guide (HAUG) is associated with improved hearing aid self-efficacy and utility performance. In Part 1, an HAUG was evaluated using the Suitability Assessment of Material (SAM) and readability formulas (Flesch Reading Ease [Flesch, 1943], Flesch-Kincaid Readability Formula [Kincaid, Fishburne, Rogers, & Chissom, 1957], and Simple Measure of Gobbledygook [McLaughlin, 1969]). The HAUG was revised using results from the SAM and best practice guidelines. The revision included generating a video. In Part 2, 30 adults with hearing impairment were randomly assigned to use either the original guide (N = 15) or the revised guide and video (N = 15) to perform a utility task. Participants' self-efficacy was measured using the Basic and Advanced Handling subscales of the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids questionnaire. SAM and readability were compared between the original and revised guides (Doak, Doak, & Root, 1996). SAM and readability were improved following the revision. Participants in the revised guide group performed significantly better on the utility task and on the Measure of Audiologic Rehabilitation Self-Efficacy for Hearing Aids subscales than participants in the original guide group. These results are encouraging as they indicate that there is scope to influence self-efficacy and utility performance through the use of appropriate HAUGs.

Full Text Available The present longitudinal study (two waves, conducted on a population of 274 secondary-school teachers, expands on previous research on burnout and work engagement. Accordingly, the effect of organizational factors (obstacles, facilitators as well as personal resources (self-efficacy on burnout and engagement is tested longitudinally following the Social Cognitive Theory. More specifically, we test the loss and gain cycles, and reciprocal relationships concerning burnout, engagement, and self-efficacy over time. Four questions are addressed: (1 Are obstacles positively related to burnout and work self-efficacy over time? (2 Are facilitators positively related to engagement and self-efficacy over time? (3 Is work self-efficacy negatively related to burnout and obstacles over time? and (4 Is work self-efficacy positively related to engagement and facilitators over time? The results of a hard-copy survey carried out at two waves (8 months between the two times, which were computed on Structural Equation Modeling show that obstacles are positively related to burnout, which in turn is positively related to self-efficacy over time. Likewise, facilitators are positively related to engagement and self-efficacy, which in turn is positively related to facilitators over time. These findings suggest a positive gain cycle in which self-efficacy plays a central role.

Clinical nurses play a vital role in clinical practice education; thus, it is necessary to help clinical nurses have teaching efficacy through the development and application of systematic education programs. To identify nurses' teaching efficacy for clinical education and analyze the influencing factors of teaching efficacy. The study used a cross-sectional design. We used a convenience sample of 263 nurses from two hospitals. Teaching efficacy, general characteristics, and perception of clinical practice education were collected via self-reported questionnaires. Teaching efficacy was measured using Hwang's (2006) questionnaire, while perception of clinical practice education was measured using the Clinical Nurse Teacher Survey developed by Nishioka et al. (2014). Participants completed the questionnaire directly. The collected data were then analyzed using descriptive statistics, t-tests, ANOVAs, and multiple regression analysis with PASW Statistics 18.0. The mean total score of teaching efficacy was 72.5 (range 21-105). The leadership for students subscale had the highest score (3.56±0.59). The factors influencing teaching efficacy were length of clinical career (β=0.26, pteaching efficacy in nurses. Based on these results, nursing educators might need to develop greater confidence in their knowledge and enhance control of their teaching strategies. Nursing schools and hospitals might need to provide greater support and educational opportunities to nurse clinical practice instructors. Furthermore, constructing a system of cooperation between these colleges and educational hospitals, developing programs to enhance teaching efficacy, and identifying the clinical instructor's role are all necessary to promote clinical practice education.

Full Text Available The Synthetic and botanical insecticides are relatively safer for environment and beneficial insects. The study was conducted in Rahim Yar Khan during the cotton cropping season 2014 to evaluate the comparative efficacy of two Synthetic insecticides i.e. Nitenpyram (Jasper 10% SL and Pyriproxyfen (Bruce 10.8% EC and two botanical extracts of Calotropic procera and Azadirachta indica, against sucking insect pest complex of cotton and their natural enemies. Upon reaching economic thresholds, the recommended field doses of all the insecticides were applied on cotton cultivar MNH-886. Data against sucking pests and their natural enemies was recorded 24 hours prior to insecticidal application and then 24, 48, 72 and 96 hours after insecticidal application. Results revealed that Nitenpyram was much toxic against sucking pests followed by Pyriproxyfen as compared to two botanical extracts. On the other hand, the synthetic insecticides did not prove safer for natural enemies as compared to botanical extracts. It was concluded that as an Integrated Pest Management (IPM strategy, botanical extracts can be used at low infestation levels so that ecosystem service of biological control may be sustained.

Microwave ablation (MWA) can be used to treat severe secondary hyperparathyroidism; however, its efficacy and the predictor of its efficacy are unclear. In this retrospective study we determined the predictor of efficacy of MWA and compared the efficacy of MWA and parathyroidectomy. Patients with severe secondary hyperparathyroidism who had received MWA or parathyroidectomy were enrolled in the study. Participants with MWA were divided into response and no response groups based on efficacy. Possible predictors were analysed using logistic regression to determine efficacy predictors. The participants were divided into MWA and parathyroidectomy groups, and the efficacy (including rates of achieving recommended goals for intact parathyroid hormone (iPTH), calcium, and phosphorus levels) were compared between the two groups. Thirty-one participants were enrolled for predictor analysis. Only baseline iPTH level predicted efficacy (OR 0.997, P = 0.018). The optimal threshold value of iPTH for predicting efficacy was 1493.5 pg/mL. To compare efficacy, 30 patients were enrolled in MWA (18/30) and parathyroidectomy (12/30) groups. The rates of achieving recommended goals for iPTH levels varied between 0 and 60%; a significant difference was found between the groups at 5 months (P = 0.01). However, in the parathyroidectomy group, the iPTH level and rate of iPTH secondary hyperparathyroidism; parathyroidectomy is more effective for severe secondary hyperparathyroidism than MWA.

To assess the efficacy of linezolid compared with vancomycin in an experimental model of pneumonia induced by methicillin-resistant Staphylococcus aureus (MRSA) in ventilated pigs. Forty pigs (30 kg) were intubated and challenged via bronchoscopy with a suspension of 106 colony forming units of MRSA into every lobe. Afterwards, pigs were ventilated up to 96 hours. Twelve hours after bacterial inoculation, the animals were randomized into 4 groups of treatment: group 1, control; group 2, vancomycin twice daily; group 3, continuous infusion of vancomycin; and group 4, linezolid. Clinical and laboratory parameters were monitored throughout the study. Bacterial cultures of bronchoalveolar lavage fluid and lung tissue samples were performed at the end of the study. Measurements of histopathology derangements of lung samples and studies of intrapulmonary drug penetration were performed. A total of 34 animals completed the study. No differences in clinical and laboratory parameters were observed. The percentage of bronchoalveolar lavage fluid and lung tissue samples with positive cultures for MRSA in controls and groups 2, 3, and 4 was respectively 75%, 11%, 11%, and 0% (p pneumonia in 95%, 69%, 58%, and 57% and signs of severe pneumonia in 48%, 29%, 22%, and 0% of controls and groups 2, 3, and 4, respectively (p treatments. In this animal model of MRSA pneumonia, linezolid showed a better efficacy than vancomycin showed because of a better pharmacokinetics/pharmacodynamics index.

Full Text Available The objective of this study was to compare the efficacy of tulathromycin (TUL with a combination of florfenicol (FFC and long-acting oxytetracycline (LAOTC in the treatment of naturally occurring undifferentiated respiratory diseases in large numbers of sheep. In this study, seven natural outbreaks of sheep pneumonia in Garmsar, Iran were considered. From these outbreaks, 400 sheep exhibiting the signs of respiratory diseases were selected, and the sheep were randomly divided into two equal groups. The first group was treated with a single injection of TUL (dosed at 2.5 mg/kg body weight, and the second group was treated with concurrent injections of FFC (dosed at 40 mg/kg bwt and LAOTC (dosed at 20 mg/kg bwt. In the first group, 186 (93% sheep were found to be cured 5 days after the injection, and 14 (7% sheep needed further treatment, of which 6 (3% were cured, and 8 (4% died. In the second group, 172 (86% sheep were cured after the injections, but 28 (14% sheep needed further treatment, of which 10 (5% were cured, and 18 (9% died. This study revealed that TUL was more efficacious as compared to the combined treatment using FFC and LAOTC. As the first report, this field trial describes the successful treatment of undifferentiated respiratory diseases in large numbers of sheep. Thus, TUL can be used for the treatment of undifferentiated respiratory diseases in sheep. [J Adv Vet Anim Res 2015; 2(3.000: 279-284

The beneficial effects of tiotropium bromide, a long acting anticholinergic bronchodilator, in the management of chronic obstructive pulmonary disease have been shown in previous studies. The present study aimed to compare the efficacy and safety of generic (Tiova®) and brand-name (Spiriva®) tiotropium preparations in patients with COPD. In this randomized double-blind parallel-group trial, 79 patients with documented COPD were assigned to Tiova® or Spiriva® for a period of 4 weeks. Assessment of pulmonary function (using spirometry), quality-of-life (using St. George respiratory Questionnaire [SGRQ]) and severity of respiratory symptoms (using breathlessness, cough and sputum scale [BCSS]) was performed at baseline and at the end of treatment period. There were significant increases in FEV1 and reductions in FVC by the end of study in both Tiova® and Spiriva® groups. FEV1/FVC ratio did not change significantly neither in the Tiova® nor in Spiriva® group. Overall SGRQ score as well as subscale scores of symptoms, activity and impacts were improved by both drugs. In the BCSS scale, the frequency and severity of three main symptoms (dyspnea, cough and sputum) was decreased by both drugs. Baseline as well as post-treatment values of spirometric parameters, SGRQ and BCSS scores was comparable between the groups, apart from a lower post-treatment frequency of cough and sputum in the Spiriva® versus Tiova® group. There was no report of adverse events in either of the study groups. The findings of this comparative trial showed equivalent efficacy and safety of Spiriva® and Tiova® in lessening the symptoms as well as improving the quality of life in patients with COPD. This finding has an important translational value given the significantly lower costs of generic versus brand-name products.

This study compared effects of two parent-mediated interventions on joint engagement outcomes as augmentations of an early intervention program for toddlers with autism spectrum disorder (ASD). Participants included 86 toddlers (range 22-36 months) with ASD and their primary caregiver. Caregiver-child dyads were randomized to receive 10 weeks of hands-on parent training in a naturalistic, developmental behavioral intervention (joint attention, symbolic play, engagement and regulation-JASPER) or a parent-only psychoeducational intervention (PEI). Dose was controlled in terms of researcher-parent contact and early intervention services received by the child. Results yielded significant effects of the JASPER intervention on the primary outcome of joint engagement. The treatment effect was large (Cohen's f² = .69) and maintained over the 6-month follow-up. JASPER effects were also found on secondary outcomes of play diversity, highest play level achieved, and generalization to the child's classroom for child-initiated joint engagement. The PEI intervention was found to be effective in reducing parenting stress associated with child characteristics. All secondary effects were generally small to moderate. These data highlight the benefit of a brief, targeted, parent-mediated intervention on child outcomes. Future studies may consider the combination of JASPER and PEI treatments for optimal parent and child outcomes. Trial registry no. NCT00999778. (c) 2015 APA, all rights reserved).

Concurrent progressive-ratio schedules: built-in controls in the study of delayed reward efficacy.

Science.gov (United States)

Jarmolowicz, David P; Hudnall, Jennifer L

2014-08-15

Delayed rewards maintain lower rates of operant responding than immediate rewards, and when given a choice between immediate and delayed rewards, individuals typically choose the immediate reward, even when it is smaller (a phenomenon called delay discounting). The behavioral and neural mechanisms underlying these behavioral patterns, however, are not conclusively understood. The present study developed a method to examine the efficacy of delayed rewards in a way that is suitable for pharmacological manipulation of delayed reward efficacy (while controlling for general changes in reward efficacy). The progressive ratio (PR) paradigm often used to examine reward efficacy was modified such that two PR schedules for lever pressing concurrently yet independently were presented. Across a series of conditions, a range of delays (3-81s) were arranged on one of the levers while the reward on the other lever remained immediate. PR breakpoints (the highest ratio completed on each lever, our measure of reward efficacy) systematically decreased on the delayed, but not on the immediate reward lever, suggesting that delays decreased reward efficacy. This decrease in breakpoint resulted in bias in within-session responding that was accounted for by models that adjusted reward value by the delay to that reward. Unlike the standard PR paradigm, the present arrangement provided the controls needed to differentiate delay specific from general changes in reward efficacy. The present method should be helpful in the study of the behavioral and neural mechanisms of delayed reward efficacy. Modifications of the present paradigm should be useful for pharmacological studies. Copyright © 2014 Elsevier B.V. All rights reserved.

Falls are common in frail older adults and often result in injuries and hospitalisation. The Nintendo® Wii™ is an easily available exercise modality in the community which has been shown to improve lower limb strength and balance. However, not much is known on the effectiveness of the Nintendo® Wii™ to improve fall efficacy and reduce falls in a moderately frail older adult. Fall efficacy is the measure of fear of falling in performing various daily activities. Fear contributes to avoidance of activities and functional decline. This randomised active-control trial is a comparison between the Nintendo WiiActive programme against standard gym-based rehabilitation of the older population. Eighty subjects aged above 60, fallers and non-fallers, will be recruited from the hospital outpatient clinic. The primary outcome measure is the Modified Falls Efficacy Scale and the secondary outcome measures are self-reported falls, quadriceps strength, walking agility, dynamic balance and quality of life assessments. The study is the first randomised control trial using the Nintendo Wii as a rehabilitation modality investigating a change in fall efficacy and self-reported falls. Longitudinally, the study will investigate if the interventions can successfully reduce falls and analyse the cost-effectiveness of the programme.

A comprehensive comparison of the efficacy and tolerability of racecadotril with other treatments of acute diarrhea in adults

Directory of Open Access Journals (Sweden)

Wolfgang Fischbach

2016-10-01

Full Text Available Racecadotril is a guideline-recommended treatment to alleviate symptoms of acute diarrhea. A systematic review of randomized studies was performed comparing efficacy and safety of treatment with racecadotril to that with placebo or active treatments in adults. In five double-blind studies, racecadotril and placebo had comparable tolerability but racecadotril was more effective. This was consistent across multiple efficacy parameters including duration of diarrhea, number of diarrheic stools, abdominal pain and meteorism; it was also consistent across countries in Africa, Asia and Europe. In six randomized studies in outpatients comparing racecadotril to loperamide, resolution of symptoms occurred with similar speed and efficacy; however, racecadotril treatment was associated with less rebound constipation and less abdominal discomfort. A seventh comparative study performed in geriatric nursing home residents reported a superior efficacy of racecadotril. In direct comparison with Saccharomyces boulardii treatment, racecadotril exhibited similar tolerability but was more efficacious. One study compared racecadotril to octreotide in patients with acute diarrhea requiring hospitalization, rehydration and antibiotic treatment; in this cohort, octreotide was more efficacious than racecadotril. In conclusion, in adults with acute diarrhea racecadotril is more efficacious than placebo or Saccharomyces boulardii, similarly efficacious as loperamide and, in patients with moderate to severe disease as add-on to antibiotics, less than octreotide. The tolerability of racecadotril is similar to that of placebo or Saccharomyces boulardii and better than that of loperamide, particularly with regard to risk of rebound constipation. Taken together these data demonstrate that racecadotril is a suitable treatment to alleviate symptoms of acute diarrhea in adults.

Ticks are increasingly reported on cats worldwide, with Ixodes ricinus being a relevant species across Europe and in near by areas of North Africa and the Middle East. Yet there are few acaracidal products with proven efficacy approved for use in cats. The objective of this study was to compare the efficacy of a new spot-on formulation containing selamectin and sarolaner with a topical application of fluralaner (Bravecto®) against Ixodes ricinus ticks on cats. To that end, twenty-four (24) cats were randomly allocated to one of three treatment groups. The cats in the control group remained untreated. Cats in group 2 were treated with selamectin/sarolaner (Stronghold®Plus; Zoetis) at the minimum recommended dose of 1.0 mg/kg sarolaner and 6.0 mg/kg selamectin on Days 0, 30 and 60. The cats in group 3 received a fluralaner treatment (Bravecto®spot-on solution for cats, MSD) at the minimum recommended dose of 40.0 mg/kg on Day 0. Cats were infested with 50 (± 4) viable, adult, unfed I. ricinus ticks on Days 26, 54, 82 and 89 and ticks were removed for counting 48 h (± 2 h) later. Three monthly treatments with selamectin/sarolaner provided high and consistent efficacy against I. ricinus for the entire duration of the study period. In contrast, the efficacy of fluralaner declined in the second month after treatment and was below the efficacy threshold of 90% on Days 56, 84 and 91. The percentage efficacy against I. ricinus was numerically higher in the selemectin/sarolaner treated group than in the fluralaner-treated group on Days 56, 84 and 91. Furthermore, greasiness and spiking of the hair, as well as white deposits were frequently observed in the fluralaner-treated cats. The results of the present study confirm the high and consistent efficacy of a new spot-on combination product containing selamectin and sarolaner against I. ricinus in cats, and indicate a decline in fluralaner efficacy during the 91 day period after treatment.

We evaluated the long-term efficacy of raltegravir according to HIV-1 subtype (B and non-B) using data from three phase III studies in treatment-experienced (BENCHMRK-1 and 2) and treatment-naive (STARTMRK) HIV-infected patients. HIV-1 subtypes were identified from baseline plasma specimens using genotypic data of the PhenoSense GT test (Monogram Biosciences, South San Francisco, California, USA). Non-B subtypes were combined for the current analyses due to small numbers of each specific subtype. An observed failure approach was used (only discontinuations due to lack of efficacy were treated as failures). Resistance evaluation was performed in patients with documented virologic failure. Seven hundred and forty-three patients received raltegravir and 519 received comparator (efavirenz in STARTMRK; optimized background therapy in BENCHMRK). Non-B subtype virus (A, A/C, A/D, A/G, A1, AE, AG, B/G, BF, C, D, D/F, F, F1, G, and complex) was isolated at baseline in 98 (13%) raltegravir recipients and 62 (12%) comparator recipients. Subtypes AE and C were most common, isolated in 41 and 43 patients, respectively. The proportion of raltegravir recipients achieving HIV RNA less than 50 copies/ml was similar between non-B and B subtypes (STARTMRK: 94.5 vs. 88.7%; BENCHMRK-1 and 2: 66.7 vs. 60.7%); change in CD4 cell count also was similar between non-B and B subtypes (STARTMRK: 243 vs. 221 cells/μl; BENCHMRK-1 and 2: 121 vs. 144 cells/μl). Phenotypic resistance to raltegravir in non-B virus was associated with integrase mutations observed previously in subtype B virus. In phase III studies in treatment-naive and treatment-experienced patients, raltegravir showed comparable and potent clinical efficacy against B and non-B HIV-1 subtypes.

Opioid-induced constipation (OIC) is a side effect of opioid therapy that can affect quality of life, adherence to treatment, and morbidity and possibly mortality. To investigate whether docusate sodium, sennosides, and lactulose have equal efficacy and side effect profiles compared to PEG in the management of OIC in adults. A systematic review was undertaken. Randomized controlled trials of adults taking opioids for cancer or non-cancer pain were considered if they met inclusion criteria. Statistical pooling was not possible as no studies met inclusion criteria. Large, well-powered, randomized controlled trials are feasible. Standard definitions of OIC would assist with the execution of these studies and contribute to their internal and external validity. Further research is strongly encouraged.

The low efficacy of rotavirus vaccines in clinical trials performed in low-resource settings may be partially explained by acquired immunity from natural exposure, especially in settings with high disease incidence. In a clinical trial of monovalent rotavirus vaccine in Bangladesh, we compared the original per-protocol efficacy estimate to efficacy derived from a recurrent events survival model in which children were considered naturally exposed and potentially immune after their first rotavirus diarrhea (RVD) episode. We then simulated trial cohorts to estimate the expected impact of prior exposure on efficacy estimates for varying rotavirus incidence rates and vaccine efficacies. Accounting for natural immunity increased the per-protocol vaccine efficacy estimate against severe RVD from 63.1% (95% confidence interval [CI], 33.0%-79.7%) to 70.2% (95% CI, 44.5%-84.0%) in the postvaccination period, and original year 2 efficacy was underestimated by 14%. The simulations demonstrated that this expected impact increases linearly with RVD incidence, will be greatest for vaccine efficacies near 50%, and can reach 20% in settings with high incidence and low efficacy. High rotavirus incidence leads to predictably lower vaccine efficacy estimates due to the acquisition of natural immunity in unvaccinated children, and this phenomenon should be considered when comparing efficacy estimates across settings.

Understanding motivational factors related to physical activity (PA) maintenance is essential in promoting long-term exercise benefits. This study explored the impact of self-efficacy (SE) on post-intervention PA maintenance in patients with hip osteoarthritis. An SE-theory based mixed-methods sub-study of a trial investigating the effects of 4 months supervised exercise in patients with hip osteoarthritis. Questionnaire data (n = 52; baseline and 12 months) on PA and SE (Arthritis Self-Efficacy Scale, ASES, score-range 10-100) were analysed (Mann-Whitney test) for differences in characteristics of maintainers and non-maintainers. Semi-structured individual interviews (n = 15; at 12-months follow-up) were analysed using directed content analysis. Compared to non-maintainers (n = 9; 17%) maintainers (n = 31; 60%) had improved (p exercise outcome expectations and obligation towards the study influenced maintenance. SE contributes to understanding of post-intervention PA maintenance in patients with hip osteoarthritis. However, disease-related factors and clinical trial participation appears significant too. Implications for Rehabilitation Patients' perceived self-efficacy for physical activity contributes to the understanding of post-intervention physical activity maintenance in patients with hip osteoarthritis. Practitioners may benefit from incorporating the self-efficacy theory in the planning and execution of exercise interventions to promote post-intervention physical activity maintenance and long term health benefits. Post-intervention physical activity maintenance may be increased by focussing on the patients' exercise self-efficacy through verbal persuasion and support, disease-specific information and information on normal physiological responses to exercise combined with an individualised training progression to support experiences of success and achievement of desired outcomes.

Characteristics of relationship itself play an important role in determining well-being of individuals who participate in the relationship. We used efficacy expectations mutually shared between close friends or romantic partners as a characteristic of relationship and investigated its impact on their life satisfaction. In Study 1, we conducted a cross-sectional study among 137 pairs of close same-sex friends to test whether the efficacy expectations shared between friends are associated with levels of life satisfaction. In Study 2, we conducted a longitudinal study among 114 heterosexual romantic couples to test predictive validity of the efficacy expectations shared between couples predict levels of life satisfaction 2 month later. In both studies we found a consistent result that as degrees of the efficacy expectations shared between individuals in a relationship increased, the degree of their life satisfaction also increased. Underlying mechanisms that explain how characteristics of relationship itself increase life satisfaction are discussed. PMID:27437946

To evaluate and compare the efficacy, cleaning ability of hand and two rotary systems in root canal retreatment. Sixty extracted premolars were retreated with following systems: Group -ProTaper Universal retreatment files, Group 2-ProFile system, Group 3-H-file. Specimens were split longitudinally and amount of remaining gutta-percha on the canal walls was assessed using direct visual scoring with the aid of stereomicroscope. Results were statistically analyzed using ANOVA test. Completely clean root canal walls were not achieved with any of the techniques investigated. However, all three systems proved to be effective for gutta-percha removal. Significant difference was found between ProTaper universal retreatment file and H-file, and also between ProFile and H-file. Under the conditions of the present study, ProTaper Universal retreatment files left significantly less guttapercha and sealer than ProFile and H-file. Rotary systems in combination with gutta-percha solvents can perform superiorly as compared to the time tested traditional hand instrumentation in root canal retreatment.

Comparative insecticidal efficacy of metofluthrin, a newly synthesized pyrethroid, and other pyrethroids against several colonies of Asian Culex quinquefas-ciatus (from Indonesia, Thailand, Vietnam and Malaysia) was evaluated by topical application. Metofluthrin was the most effective against the four colonies of Cx. quinquefasciatus. The LD50-based relative effective ratio of metofluthrin against d-allethrin was higher in Cx. quinquefasciatus (33.3 to 78.8) than in Cx. pipiens pallens (27.8)...

Full Text Available Aim and Objective: To compare efficacy and safety of escitalopram with desvenlafaxine in the treatment of major depression.Materials and Methods: A total of 60 patients of depression were randomized into two groups after meeting inclusion criterion. In the first 3 weeks, escitalopram 10 mg/day was given and then 20 mg/day for the next 3 weeks in group 1 (n = 30. Desvenlafaxine in the first 3 weeks was given 50 mg/day and 100 mg/day for the next 3 weeks in group 2 (n = 30. The parameters evaluated during the study were efficacy assessments byHamilton Scale of Rating Depression (HAM-D, Hamilton Rating Scale of Anxiety (HAM-A, and Clinical Global Impression (CGI. Safety assessments were done by UKU-scale. Results: Escitalopram and desvenlafaxine significantly (P < 0.001, reduced HAM-D, HAM-A, and CGI scores from their respective base lines. However, on comparison failed show any statistical difference at 3 and 6 weeks of treatment. Escitalopram and desvenlafaxine were both found to be safe and well-tolerated and there was not much difference between the two groups as evident from UKU Scale and their effect on various biochemical parameters. Conclusion: The present study demonstrated similar efficacy and safety in reducing depression and anxiety with both escitalopram and desvenlafaxine, but clinical superiority of one drug over the other cannot be concluded due to limitations of the small sample size.

The need to assess relative efficacy in the absence of comparative clinical trials is a problem that is often encountered in economic modeling. The use of matching adjusted indirect comparison (MAIC) in this situation has been suggested. We present the results of a MAIC used to evaluate the incremental benefit offered by adding simeprevir (SMV) to standard therapy in the treatment of patients infected with genotype 4 hepatitis C virus (HCV). Individual patient data for a single arm study evaluating the use of SMV with peginterferon alfa 2a + ribavirin (PR) in genotype 4 HCV were available (RESTORE study). A systematic literature review was used to identify studies of PR alone used in the same patient group. By applying the inclusion criteria for each study in turn to the RESTORE dataset and then applying the published MAIC covariate matching algorithm, a series of pseudosamples from RESTORE were generated. After assessment of the matching outcomes, the best matched comparisons were used to derive estimates of efficacy for SMV + PR in patients equivalent to those participating in the PR trial. Five potential comparator studies were identified. After applying the matching process, two emerged as offering the greatest equivalence with the generated RESTORE pseudosamples and were used to estimate SMV + PR efficacy, expressed as the percentage of patients achieving sustained viral response (SVR). In one comparison, SVR in the SMV + PR group was 85% versus 63% for PR alone. In the second comparison, the corresponding SVRs were 77% and 44% respectively. After matching for varying baseline characteristics, both comparisons of RESTORE versus studies of PR alone yielded a benefit for SMV + PR vs PR alone in genotype 4 HCV-infected patients. The incremental gain in SVR associated with use of SMV ranged from 22% to 33%. In the absence of direct comparative studies, the MAIC gives a better perspective than simple comparison of absolute SVR from individual

Amebic liver abscess (ALA) is a common and serious problem in our country. There are only a few controlled trials on the efficacy and advantages of combination therapy with percutaneous needle aspiration and pharmacotherapy, over pharmacotherapy alone for amebic liver abscess. This study was conducted to compare the efficacy of two different treatment modalities i.e. drug treatment alone vs. drug treatment and aspiration of abscess cavity in patients with small (up to 5 cm) and large (5 cm to 10 cm) size ALA. This is one of the largest single center, prospective, randomized studies comparing the efficacy of aspiration in ALA. (i) Mean body temperature, liver tenderness, total leukocyte count (TLC), serum alanine aminotransferase (ALT) and liver span were significantly decreased in the aspiration group on days 8 and 15 as compared to non-aspiration group especially in large abscess (5 cm to 10 cm). (ii) Abscess cavity maximum diameter decreased significantly in aspiration group on days 8 and 15, and 1 month & 3 months in large abscess (5cm to 10 cm). (i) Needle aspiration along with metronidazole hastens clinical improvement especially in large (5 cm up to 10 cm) cavities in patients with ALA. (ii) Aspiration is safe and no major complications occurred. (iii) Hence, combination therapy should be the first choice especially in large ALA (5 cm to 10 cm).

The study aims to compare the efficacy and safety of over-the-counter whitestrips with the American Dental Association (ADA)-recommended home-whitening using the 10 % carbamide peroxide gel. Randomized controlled trials (RCTs) comparing the clinical efficacy and safety of the whitestrips with the 10 % carbamide peroxide (10 % CP) gel applied on tray for tooth whitening in adults were searched at PubMed and Cochrane Central Register of Controlled Trials databases and selected up to October 2014. Efficacy of the whitening techniques was assessed through ∆E, ∆L, and ∆b parameters, while side effects were analyzed as dichotomous variables. Data was extracted independently by two reviewers. Metanalysis was performed using random- and fixed-effect models (RevMan 5.3). Eight studies were included in the metanalysis. The metanalysis revealed no significant difference between the intervention groups for tooth-whitening efficacy measured as ΔE (mean difference [MD]-0.53; 95 % CI [-1.72;0.66]; Z = 0.88; p = 0.38) and ΔL (MD-0.22; 95 % CI [-0.81;0.36]; z = 0.75; p = 0.45); reduction of yellowing was higher with the whitestrips (MD-0.47; 95 % CI [-0.89; -0.06]; Z = 2.25; p = 0.02). Tooth sensitivity (risk ratio [RR] 1.17; 95 % CI [0.81-1.69]; Z = 0.81; p = 0.42) and gingival sensitivity (RR 0.76; 95 % CI [0.53-1.10]; Z = 1.44; p = 0.15) were similar, regardless of the whitening method used. The observed gingival irritation was higher when the 10 % CP gel was applied on tray (RR 0.43; 95 % CI [0.20-0.93]; Z = 2.14; p = 0.03). The quality of evidence generated was rated very low for all outcomes. There is no sound evidence to support the use of the whitening strips in detriment of the ADA-recommended technique based on the 10 % carbamide peroxide gel applied on tray. To the moment, there is no sound evidence in dental literature to suggest that the ADA-recommended whitening technique based on 10 % carbamide peroxide gel could be substituted by the whitening strips.

Patients and methods: We conducted a systematic search in several electronic databases as well as manual search in bibliographies of relevant studies. We included randomized controlled trials that investigated the efficacy and safety of saffron for treating MDD in adults in comparison to either placebo or synthetic antidepressants. Primary outcome was change in scores on depressive symptoms from baseline. Secondary outcomes included remission rate, response rate, and drop-out rate for all reasons. We chose a random-effects model in order to obtain more conservative results. Standardized mean differences (SMDs and odds ratios (ORs with 95% confidence intervals (CIs were estimated as the overall effect index by inverse variance models. Results: Seven studies were included in this meta-analysis. Overall quality of these included studies was moderate. As for the primary outcome, saffron showed more improvements in depression symptoms when compared with placebo, with an SMD of -1.22 (95% CI -1.94, -0.49, P=0.001. Meanwhile, saffron was as effective as synthetic antidepressants, with an SMD of 0.16 (95% CI -0.25, 0.57, P=0.44. Moderate heterogeneity existed in our analysis. Through subgroup analyses, we found that treatment dosage and duration, types of synthetic antidepressants administered in the comparison group, and outcome measures could explain most of the variance. No differences were found in remission rate, response

A comparative evaluation of efficacy of magneto- and laser therapy was carried out in 82 patients with osteoarthrosis deformans. The magnetic field and laser irradiation dispelled the pain syndrome and synovitis manifestations. It is recommendable that the multiple-modality therapy of patients with osteoarthrosis deformans should involve magneto- and laser therapy (15 to 20 procedures per one course) that improve results of the treatment being received and allow the time of hospitalization to be reduced at an average by 5 bed-days. Laser appeared to be a very effective mode of treatment. No unfavourable side effects were recordable.

Full Text Available Background: Periodontal diseases are chronic bacterial infections that lead to gingival inflammation, periodontal tissue destruction, and alveolar bone loss. Acting as powerful allies in the fight against periodontal disease, natural compounds can help safeguard against lethal age-related diseases that emanate from our mouths. Punica granatum (pomegranate shrub belongs to the Punicaceae family which has been used as an astringent, hemostatic, antidiabetic, antihelmintic, and also for diarrhea and dysentery. The aim of the present work was to investigate the possible efficacy of hydroalcoholic extract from Punica granatum fruit as an antiplaque and antigingivitis agent when compared with chlorhexidine. Materials and Methods: Twenty subjects diagnosed with chronic generalized gingivitis were selected and randomly divided into two groups: Group 1 - Pomegranate mouthwash and Group 2 - Chlorhexidine mouthwash. Punica granatum mouthwash was prepared using raw Punica granatum fruit. Patients were instructed to use the prescribed mouthwash for 15 days. Clinical evaluation was undertaken using the gingival index, the plaque index, and bleeding on probing at baseline, 7 days, and 15 days. Results: The clinical study observed significant improvement in gingival status in both the sites (P<0.05. Subjects using Punica granatum mouthwash showed significant improvement in bleeding and gingivitis score as compared with chlorhexidine. In contrast, Punica granatum was shown not to be so effective in reducing plaque scores. Chlorhexidine still remains as a standard in the reduction of plaque in subjects with gingivitis. Conclusion: Punica granatum mouthwash is beneficial in improving gingival status due to its profound styptic action, with sufficient reduction in plaque scores.

In this project, we examined the effect of a 4-month intervention with horses on perceived social support, self-esteem and general self-efficacy among Norwegian adolescents aged 12–15 years. The intervention took place at farm-based stables and included work with the horses and riding. A waiting-list crossover design was used and the participants answered questionnaires at three time periods. Study I (N = 49) examined the effect of the intervention compared with the control group. Study II (N = 41) examined the relationship between the same psychological variables and change in mastering skills with horse. The intervention group reported a significant increase in perceived social support compared with the control group. There were no differences in self-esteem and general self-efficacy between the groups. The results from study II showed that a lower level of perceived social support prior to the intervention predicted an increase in mastering skills with the horse during the intervention.

Full Text Available Abstract Background Falls are common in frail older adults and often result in injuries and hospitalisation. The Nintendo® Wii™ is an easily available exercise modality in the community which has been shown to improve lower limb strength and balance. However, not much is known on the effectiveness of the Nintendo® Wii™ to improve fall efficacy and reduce falls in a moderately frail older adult. Fall efficacy is the measure of fear of falling in performing various daily activities. Fear contributes to avoidance of activities and functional decline. Methods This randomised active-control trial is a comparison between the Nintendo WiiActive programme against standard gym-based rehabilitation of the older population. Eighty subjects aged above 60, fallers and non-fallers, will be recruited from the hospital outpatient clinic. The primary outcome measure is the Modified Falls Efficacy Scale and the secondary outcome measures are self-reported falls, quadriceps strength, walking agility, dynamic balance and quality of life assessments. Discussions The study is the first randomised control trial using the Nintendo Wii as a rehabilitation modality investigating a change in fall efficacy and self-reported falls. Longitudinally, the study will investigate if the interventions can successfully reduce falls and analyse the cost-effectiveness of the programme.

Venom immunotherapy (VIT) is recommended as the first-line treatment for patients allergic to Hymenoptera venom. To analyze the safety and efficacy of VIT in a real life setting. One hundred and eighty patients undergoing VIT were studied to evaluate the safety, efficacy, incidence and nature of symptoms after field stings and adverse reactions to VIT. Significantly more patients were allergic to wasp than bee venom (146 vs. 34, p bees, and were not associated with angiotensin convertase inhibitors (ACEi) or β-adrenergic antagonists use. Systemic reactions were observed in 4 individuals on wasp VIT (2.7%) and in 6 patients allergic to bees (17.65%). The VIT was efficacious as most patients reported no reactions (50%) or reported only mild local reactions (43.75%) to field stings. The decrease in sIgE at completion of VIT correlated with the dose of vaccine received ( r = 0.53, p = 0.004). Beekeeping (RR = 29.54, p venom allergy. Venom immunotherapy is highly efficacious and safe as most of the adverse events during the induction and maintenance phase are mild and local. Side effects of VIT are more common in subjects on bee VIT. Beekeeping and female sex are associated with a higher risk of allergy to Hymenoptera venom.

The objective of the present research was to study the dynamics of changes in emotional energy, work self-efficacy and perceived similarity in the crew of the Mars 520 experimental study. The study comprised six volunteers, all men, between 27-38 yr of age (M = 32.16; SD = 4.99). The Mars 520 experimental study simulated all the elements of the proposed Mars mission that could be ground simulated, i.e., traveling to Mars, orbiting it, landing, and returning to Earth. During the simulation, measures of emotional energy, work self-efficacy, and perceived similarity were repeated every month. The data were analyzed using linear mixed effect models. Emotional energy, work self-efficacy, and perceived similarity gradually increased in the course of the simulation. There was no evidence for a so-called third quarter phenomenon (the most strenuous period of group isolation, psychologically, emotionally, and socially) in our data. On the contrary, work self-efficacy, emotional energy, and group cohesion (indexed here by the subject's perceived similarity to others) increased significantly in the course of the simulation, with the latter two variables showing positive growth in the group functioning.

Despite the overall success of total hip replacement (THR) in patients with symptomatic osteoarthritis (OA), up to one-quarter of patients report suboptimal recovery. The aim of this study was to determine whether social support and general self-efficacy predict variability in short-term recovery in a Norwegian cohort. We performed secondary analysis of a prospective multicenter study of 223 patients who underwent THR for OA in 2003-2004. The total score of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) at 3 months after surgery was used as the recovery variable. We measured self-efficacy using the General Self-Efficacy Scale (GSES) and social support with the Social Provisions Scale (SPS). Preoperative and postoperative scores were compared using Wilcoxon tests. The Mann-Whitney U test compared scores between groups that differed in gender and age. Spearman's rho correlation coefficients were used to evaluate associations between selected predictor variables and the recovery variable. We performed univariate and multiple linear regression analyses to identify independent variables and their ability to predict short-term recovery after THR. The median preoperative WOMAC score was 58.3 before and 23.9 after surgery. The mean absolute change was 31.9 (standard deviation [SD] 17.0) and the mean relative change was 54.8% (SD 26.6). Older age, female gender, higher educational level, number of comorbidities, baseline WOMAC score, self-efficacy, and three of six individual provisions correlated significantly with short-term recovery after THR and predicted the variability in recovery in the univariate regression model. In multiple regression models, baseline WOMAC was the most consistent predictor of short-term recovery: a higher preoperative WOMAC score predicted worse short-term recovery (β = 0.44 [0.29, 0.59]). Higher self-efficacy predicted better recovery (β = -0.44 [-0.87, -0.02]). Reliable alliance was a significant predictor

We aimed to assess the short-term outcomes of per-oral endoscopic myotomy (POEM) compared with laparoscopic Heller myotomy (LHM) for achalasia through a meta-analysis of nonrandomized comparative studies.We searched PubMed, Embase, Medline, Cochrane Library, and Google Scholar for studies that compared POEM and LHM for achalasia and were published between January 1, 2008 and December 31, 2014. The Methodological Index for Nonrandomized Studies (MINORS) was used to evaluate the quality of the studies. Random- and fixed-effects meta-analytical models were used, and between-study heterogeneity was assessed.Four nonrandomized comparative studies that included 317 patients (125 in the POEM group and 192 in the LHM group) met our research criteria and were assessed. There were no differences between the POEM and LHM groups in terms of sex, preoperative Eckhart score, length of myotomy, operation time, length of hospital stay, and complications. The patients in the POEM group were older than those in the LHM group (MD =2.81, 95% CI 0.27-5.35; P = 0.03) with high between-study homogeneity (χ = 1.96, df = 2, I = 0%; P = 0.38). The patients in the POEM group had a lower Eckardt score after surgery compared with those in the LHM group (MD = -0.30, 95% CI -0.42 to -0.18; P < 0.001) with high between-study homogeneity (χ = 0.00, df = 1, I = 0%; P = 1.00).The efficacy and safety of POEM appear to be comparable to those of LHM. Multicenter and randomized trials with larger sample size are needed to further compare the efficacy and safety of POEM and LHM for the treatment of achalasia.

Full Text Available No prospective head-to-head trials comparing the fracture efficacy of the currently marketed weekly and monthly bisphosphonates have been conducted. Due to the large sample size such studies would require to reliably detect differences in fracture risk and the associated high costs, they are considered to be impractical. Whilst providing the highest level of evidence, clinical trials also have inherent limitations. Patients are selected by a number of criteria and therefore usually do not represent the normal patient population. Also due to a protocol, normal clinical practice is usually not reflected. In contrast, database studies allow the assessment of treatments in normal clinical practice. Whilst observational studies have limitations owing to more confounding variables, they do have an important place in evidence-based medicine (especially in the absence of prospective clinical trials, and if well-designed can give some indications regarding the comparative efficacy of osteoporosis therapies in real-world clinical practice.

Regulatory agencies recommend a stepwise approach for demonstrating biosimilarity between a proposed biosimilar and reference biological product emphasizing for functional and structural characterization to trace if there is any difference which may impact safety and efficacy. We studied the comparative structural and biological attributes of recombinant human chorionic gonadotropin (rhCG), SB005, with reference product, Ovidrel ® and Ovitrelle ® . Recombiant hCG was approved in 2000 by the US Food and Drug Administration for the induction of final follicular maturation, early luteinization in infertile women as part of assisted reproductive technology program. It is also indicated for the induction of ovulation and pregnancy in ovulatory infertile patients whose cause of infertility is not due to ovarian failure. Primary structure was studied by intact mass analysis, peptide fingerprinting, peptide mass fingerprinting and sequence coverage analysis. Higher order structure was studied by circular dichroism, ultraviolet-visible spectroscopy, fluorescence spectroscopy, and disulfide bridge analysis. Different isoforms of reference product and SB005 were identified using capillary isoelectric focusing and capillary zone electrophoresis. Glycosylation was studied by N-glycan mapping using LC-ESI-MS, point of glycosylation, released glycan analysis using ultra performance liquid chromatography and sialic acid analysis. Product related impurities such as oligomer content analysis and oxidized impurities were studied using size exclusion chromatography and reverse phase high performance liquid chromatography, respectively.

Full Text Available The purpose of the study is to explore the Malaysian rural learners self-efficacy in writing after assistance given by a teacher. The social cognitive theory aid socio-cultural theory are used as the theoretical framework to pursue the discussion on the effects of teacher’s assistance on learners writing self-efficacy. A case study approach is adopted where three learners and a teacher were chosen from a form four class through purposive sampling. Learnei-s’ Titing self-efficacy is evaluated using a writing self-efficacy scale adapted from Bottomley. Henk and Melnick (1998 and also classroom observation. Wang and Pape (2007 categories were used as guidelines to analyze observation data in order to understand the participants self-efficacy phenomena in their learning to write. Overall, this study places a heavy emphasis on the perceptions and actions of the selected form four learners and teacher through non-participant classroom observations, interviews with each learner and teacher.

Full Text Available Abstract Background The main aim of this study was to compare the safety and efficacy of IR MPH administered three times daily to those of once daily OROS-MPH. Methods Subjects were outpatient adults satisfying full diagnostic criteria for DSM-IV ADHD between 19 and 60 years of age. Data from two independently conducted 6-week placebo controlled, randomized clinical trials of IR-MPH (tid and of OROS-MPH were pooled to create three study groups: Placebo (N = 116, IR-MPH (tid (N = 102 and OROS-MPH (N = 67. Results Eight-five percent (N = 99 of placebo treated subjects, 77% (N = 79 of the IR-MPH (tid treated subjects, and 82% (N = 55 of the OROS-MPH treated subjects completed the 6-week trial. Total daily doses at endpoint were 80.9 ± 31.9 mg, 74.8 ± 26.2 mg, and 95.4 ± 26.3 mg in the OROS-MPH, IR-MPH (tid, and placebo groups, respectively. At endpoint, 66% (N = 44 of subjects receiving OROS-MPH and 70% (N = 71 of subjects receiving IR-MPH (tid were considered responders compared with 31% (N = 36 on placebo. Conclusion Comparison of data from two similarly designed, large, randomized, placebo-controlled, trials, showed that equipotent daily doses of once daily OROS-MPH had similar efficacy to that of TID administered IR MPH. Trial Registration The trial of OROS-MPH was registered at clinicaltrials.gov, number NCT00181571.

The purpose of this study was to investigate the role of task self-efficacy as a psychological factor involved in the relationship between self-control depletion and physical endurance. Participants (N = 37) completed two isometric handgrip endurance trials, separated by a Stroop task, which was either congruent (control) or incongruent (causing depletion). Task self-efficacy for the second endurance trial was measured following the Stroop task. Participants in the depletion condition reported lower task self-efficacy and showed a greater reduction in performance on the second endurance trial when compared with controls. Task self-efficacy also mediated the relationship between self-control depletion and endurance performance. The results of this study provide evidence that task self-efficacy is negatively affected following self-control depletion. We recommend that task self-efficacy be further investigated as a psychological factor accounting for the negative change in self-control performance of physical endurance and sport tasks following self-control strength depletion.

Objective:To compare the in vitro antimicrobial efficacy of ceftaroline with linezolid against Staphylococcus aureus and methicillin resistant Staphylococcus aureus. Study Design: Quasi-experimental study. Place and Duration of Study: Microbiology Department, Army Medical College, Rawalpindi, from January to December 2013. Methodology: Clinical samples from respiratory tract, blood, pus and various catheter tips routinely received in the Department of Microbiology, Army Medical College, Rawalpindi were innoculated on blood and MacConkey agar. Staphylococcus aureus was identified by colony morphology, Gram reaction, catalase test and coagulase test. Methicillin resistant Staphylococcus aureus detection was done by modified Kirby Bauer disc diffusion method using cefoxitin disc (30g) and the isolates were considered methicillin resistant if the zone of inhibition around cefoxitin disc was /sup 2/ 21 mm. Bacterial suspensions of 56 Staphylococcus aureus isolates and 50 MRSA isolates were prepared, which were standardized equal to 0.5 McFarland's turbidity standard and inoculated on Mueller-Hinton agar plates followed by application of ceftaroline and linezolid disc (Oxoid, UK), according to manufacturer's instructions. The plates were then incubated at 37 Degree C aerobically for 18 - 24 hours. Diameters of inhibition zone were measured and interpretated as per Clinical and Laboratory Standards Institute (CLSI) guidelines. Results: Out of 106 isolates all of the 56 Staphylococcus aureus (100%) were sensitive to ceftaroline and linezolid. However, out of 50 methicillin resistant Staphylococcus aureus, 48 (96%) were sensitive to ceftaroline whereas, 49 (98%) were sensitive to linezolid. Conclusion: Ceftaroline is equally effective as linezolid against Staphylococcus aureus and methicillin resistant Staphylococcus aureus. (author)

This study used variables proposed in social cognitive career theory (SCCT) to focus the evaluation of a research curriculum at the Cleveland Clinic Lerner College of Medicine of Case Western Reserve University (CCLCM). Eight cohorts of CCLCM medical students completed a web-based version of the six-scale Clinical Research Appraisal Inventory-Short Form (CRAI-SF) items at matriculation (n = 128) or graduation (n = 111) during 2009-2013. Parametric statistics were used to compare CRAI-SF scales to domains proposed in SCCT: trainees' characteristics (gender, training level, advanced degree), career interests, career intentions (medical specialty), and performance (peer-reviewed publications and required thesis topic). A number of lessons emerged in using theory to frame the evaluation of a complex educational program. Graduates rated their research self-efficacy significantly higher on all six CRAI-SF scales with large effect sizes (>.90) on five scales (Conceptualizing a Study, Study Design and Analysis, Responsible Research Conduct, Collaborating with Others, and Reporting a Study). Women and men did not have significantly different scores on CRAI-SF scales (p > .05), suggesting that the research program provides adequate supports for women students. Most thesis projects addressed clinical (36.9 %, n = 41) or translational (34.2 %, n = 38) research topics. The CRAI-SF discriminated between medical school matriculates and graduates, suggesting that research self-efficacy increases with mastery experiences. No significant relationships occurred between CRAI-SF scores and graduates' thesis topics or chosen clinical specialty. Correlations demonstrated significant relationships between graduates' perceptions of research self-efficacy and their interest in clinical research careers.
