    Dens invaginatus is a dental malformation that may give rise to several complications. Caries of the invagination can severely weaken the whole tooth, making it susceptible to fracture. Subgingival fractures are major complications threatening tooth survival and usually require periodontal/orthodontic/prosthetic treatment if long-term viability is to be ensured. This article describes a case of single-session restoration of a fractured invaginated tooth by means of endodontic treatment followed by fragment reattachment.

    Full Text Available Purpose The aim of the study was to evaluate the efficacy and safety of bilateral single-session retrograde intrarenal surgery in the treatment of bilateral renal stones. Materials and Methods From December 2008 to February 2012, 42 patients who had undergone bilateral single-session retrograde intrarenal surgery (RIRS and laser lithotripsy were included in the study. The procedures were performed in the lithotomy position on an endoscopy table under general anesthesia, beginning on the side in which the stone size was smaller. Plain abdominal radiography, intravenous urograms (IVU, renal ultrasonography (USG and / or non-contrast tomography (CT scans were conducted for all patients. The success rate was defined as patients who were stone-free or only had residual fragment less than 4 mm. Results A total of 42 patients (28 male, 14 female with a mean age 39.2 ± 14.2 were included in the present study. The mean stone size was 24.09 ± 6.37 mm with a mean operative time of 51.08 ± 15.22 minutes. The stone-free rates (SFR were 92.8% and 97.6% after the first and second procedures, respectively. The average hospital stay was 1.37 ± 0.72 days. In two patients (4.7%, minor complications (Clavien I or II were observed, whereas no major complications (Clavien III-V or blood transfusions were noted in the studied group. Conclusions Bilateral single-session RIRS and laser lithotripsy can be performed safely and effectively with a high success rate and low complication rate in patients with bilateral renal stones.

    Purpose: To develop a combined simulation and treatment workflow for MRI-guided radiation therapy using the ViewRay treatment planning and delivery system. Methods: Several features of the ViewRay MRIdian planning and treatment workflows are used to simulate and treat patients that require emergent radiotherapy. A simple “pre-plan” is created on diagnostic imaging retrieved from radiology PACS, where conformal fields are created to target a volume defined by a physician based on review of the diagnostic images and chart notes. After initial consult in radiation oncology, the patient is brought to the treatment room, immobilized, and imaged in treatment position with a volumetric MR. While the patient rests on the table, the pre-plan is applied to the treatment planning MR and dose is calculated in the treatment geometry. After physician review, modification of the plan may include updating the target definition, redefining fields, or re-balancing beam weights. Once an acceptable treatment plan is finalized and approved, the patient is treated. Results: Careful preparation and judicious choices in the online planning process allow conformal treatment plans to be created and delivered in a single, thirty-minute session. Several advantages have been identified using this process as compared to conventional urgent CT simulation and delivery. Efficiency gains are notable, as physicians appreciate the predictable time commitment and patient waiting time for treatment is decreased. MR guidance in a treatment position offers both enhanced contrast for target delineation and reduction of setup uncertainties. The MRIdian system tools designed for adaptive radiotherapy are particularly useful, enabling plan changes to be made in minutes. Finally, the resulting plans, typically 6 conformal beams, are delivered as quickly as more conventional AP/PA beam arrangements with comparatively superior dose distributions. Conclusion: The ViewRay treatment planning software and

Standard PC treatment involves multiple sessions of cognitive behavioral therapy. To provide efficient treatment, we developed a single-session, 2-hour class that solely treats PC entitled “From Catastrophizing to Recovery”[FCR].Objectives: To determine 1 feasibility of FCR; 2 participant ratings for acceptability, understandability, satisfaction, and likelihood to use the information learned; and 3 preliminary efficacy of FCR for reducing PC.Design and methods: Uncontrolled prospective pilot trial with a retrospective chart and database review component. Seventy-six patients receiving care at an outpatient pain clinic (the Stanford Pain Management Center attended the class as free treatment and 70 attendees completed and returned an anonymous survey immediately post-class. The Pain Catastrophizing Scale (PCS was administered at class check-in (baseline and at 2, and 4 weeks post-treatment. Within subjects repeated measures analysis of variance (ANOVA with Student's t-test contrasts were used to compare scores across time points.Results: All attendees who completed a baseline PCS were included as study participants (N=57; F=82%; mean age =50.2 years; PCS was completed by 46 participants at week 2 and 35 participants at week 4.

    Intense pulsed light (IPL) and fractional photothermolysis (FP) are effective nonablative treatments for photoaging. To investigate the safety and efficacy of administering these two treatments in the same session with the aim of maximizing results while maintaining safety and minimizing downtime. We sought to compare the efficacy of the combination treatment with that of individual treatments of IPL and FP by conducting a split-face study. Twenty-nine subjects received a full-face standard-strength treatment with IPL immediately followed by treatment with 1550-nm FP. A further 14 patients underwent a split-face study comparing combined IPL and FP on one side of the face with these two treatments performed in isolation, 4 weeks apart, on the other side. The combination treatment achieved results statistically superior to treatment with IPL alone, FP alone, and treatment with IPL and FP performed 4 weeks apart. Downtime and adverse events were similar to those expected with individual treatments of IPL or FP alone. Intense pulsed light and PF appear to be synergistic when performed together in a single session, and the combination treatment is associated with a good safety profile and minimal downtime. © 2012 by the American Society for Dermatologic Surgery, Inc.

    Full Text Available Objectives. To assess the treatment outcomes of a single session of whole gland high intensity focused ultrasound (HIFU for patients with localized prostate cancer (PCa. Methods. Response rates were defined using the Stuttgart and Phoenix criteria. Complications were graded according to the Clavien score. Results. At a median follow-up of 94months, 48 (44.4% and 50 (46.3% patients experienced biochemical recurrence for Phoenix and Stuttgart definition, respectively. The 5- and 10-year actuarial biochemical recurrence free survival rates were 57% and 40%, respectively. The 10-year overall survival rate, cancer specific survival rate, and metastasis free survival rate were 72%, 90%, and 70%, respectively. Preoperative high risk category, Gleason score, preoperative PSA, and postoperative nadir PSA were independent predictors of oncological failure. 24.5% of patients had self-resolving LUTS, 18.2% had urinary tract infection, and 18.2% had acute urinary retention. A grade 3b complication occurred in 27 patients. Pad-free continence rate was 87.9% and the erectile dysfunction rate was 30.8%. Conclusion. Single session HIFU can be alternative therapy for patients with low risk PCa. Patients with intermediate risk should be informed about the need of multiple sessions of HIFU and/or adjuvant treatments and HIFU performed very poorly in high risk patients.

    Music has been used as a non-pharmacological modality in the treatment of different conditions since ancient times. It has received attention in modern medicine in recent decades, particularly in geriatric population. The effects of music on mood and cognition are well documented. The aim of the current case report is to highlight the benefits of musical activities in the geriatric population. We report a naturalistic treatment outcome in an elderly patient on a geriatric psychiatric unit related to a single session of piano playing. A rapid and sustained improvement in mood and cognition of an elderly patient was observed after a single session of playing piano. Notwithstanding the limitations of a single subject, uncontrolled case study, the effect was dramatic. Our findings support previous claims regarding music therapy including effects of a single session music-based therapeutic interventions, and we conclude that music therapy for geriatric patients with mood and cognitive deficits is worth further systematic investigation.

    The purpose of this brief paper is to review the current status of one-session treatment (OST) for specific phobias in children and adolescents. Following a brief historical overview and description of OST, we systematically describe eight studies that have examined its efficacy in children and adolescents aged between 7 and17 years. We also explore phobia subtypes, age, gender, and comorbidity as possible moderators of treatment outcome. Studies have been conducted in Australia, Austria, the Netherlands, the USA, and Sweden. Although there is limited evidence that OST works better for animal phobias than other subtypes of phobias and for girls than boys, across studies there is considerable evidence that it is generally effective across phobia subtypes and for both boys and girls. No age differences in outcomes were noted, nor were any differences noted due to comorbidity. OST was found to be equally effective with children and adolescents with co-occurring multiple phobias and other anxiety disorders. Moreover, in at least one study, it was found to reduce untreated phobic and anxiety disorders in addition to the treated phobias. It is concluded that OST is a highly effective intervention for the treatment of specific phobias in children and adolescents.

    Mutism is a common manifestation of catatonia, but mutism due to other forms of psychopathology and neurological disorders have also been described. Although not common, long-standing mutism has also been a feature of non-catatonic schizophrenia and traditionally responds less to conventional therapies. We describe a rare case of paranoid schizophrenia presenting with continuous mutism for about 4 years. This 26-year-old male had symptoms of schizophrenia without catatonia. After failed trial of adequate pharmacotherapy and psychological intervention and considering his level of dysfunction, he was started on electroconvulsive therapy (ECT). To our surprise, he improved with a single session of ECT while he was on concurrent pharmacotherapy. We also discuss the possible explanation for this rapid effect of ECT in such clinical presentation. To our knowledge, this is the first case of non-catatonic mutism of schizophrenia of this long duration responding so promptly to ECT, although there are other reports as well in literature, but multiple ECT sessions were applied in those cases. Non-catatonic mutism is perhaps presenting as a cultural variant in this part of the world and whenever encountered, ECT should be an option. Further research should be carried out to validate this idea.

    To investigate the feasibility of yttrium-90 ((90)Y) glass microsphere radioembolization (including angiography, lung shunt assessment, and treatment) as a single-session, outpatient procedure. Between January 2008 and June 2013, 14 patients underwent outpatient, single-session radioembolization with (90)Y glass microspheres. As part of the routine diagnostic work-up, all patients underwent either computed tomography (CT) or magnetic resonance imaging of the liver with three-dimensional analysis and had laboratory results forwarded to our center for confirmation of candidacy before treatment. On treatment day, all patients underwent planning mesenteric angiography with flat panel cone-beam CT imaging. Patients were administered 33-85 MBq of technetium-99m macroaggregated albumin ((99m)Tc-MAA) via a microcatheter positioned in a hepatic artery supplying the tumor of interest. Planar scintigraphy was initiated within 2 hours after the administration of (99m)Tc-MAA and lung shunt fraction was determined. Final dosimetry calculations were performed while the patient was being transferred back from nuclear medicine to interventional radiology. All patients successfully underwent planning angiography with administration of (99m)Tc-MAA and (90)Y radioembolization as a single-session treatment. There were no reportable or recordable medical events; treatment was carried out to the desired dose in all cases. The mean total procedure time was 2.70 hours ± 0.72 (range, 1.63-3.97 h). This study reports a novel proof of concept for performing radioembolization in a single-session setting. By using the described method, time between initial clinical assessments and radioembolization treatment is decreased, and costs are minimized. © 2014 Published by SIR on behalf of SIR.

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002–2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2–8) days. Median survival was 26 months (95% confidence interval (CI), 19–33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2–23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    This article reports a systematic clinical case study of the psychological assessment and treatment of Daniel (9), a coloured South African boy with a diagnosis of attention deficit hyperactivity disorder (ADHD) (inattentive type). The case is of scientific interest because: (1) there was only a single treatment session, in which contingency management training was delivered to Daniel's parents and teacher; (2) there was evidence for the effectiveness of the intervention immediately and at two-year follow-up; (3) it documents the transportability to a South African context of an intervention developed by overseas research; (4) it documents the central role of case formulation in the delivery of effective psychological interventions; and (5) although Daniel met the criteria for ADHD, he also displayed symptoms of depression and social anxiety and the case supports the use of a transdiagnostic approach to case formulation. The conscientiousness with which his parents and teachers applied the programme was a major factor in the effectiveness of the intervention, and such rapid impact would not be possible where parents and teachers are unavailable or not co-operative. The publication of systematic case studies such as this one is important for the development of a local evidence-based practice in South Africa.

    PurposeThe purpose of our study is to evaluate results of percutaneous aspiration with alcohol sclerotherapy in symptomatic patients with simple hepatic cysts by employing single-session techniques either by a needle or a catheter.Materials and MethodsWe retrospectively included 39 simple hepatic cysts in 35 patients treated via percutaneous aspiration and single-session alcohol sclerotherapy between years 1993 and 2012. Indications were pain (n = 28) or ruling out cystic echinococcus (CE) disease (n = 7). 29 cysts in 26 patients were treated by needle technique (Group A) and ten cysts in nine patients were treated by single-session catheter technique (Group B). Patients were followed for 4–173 months (median: 38 months).ResultsAll patients were successfully treated. Before procedure, cyst volumes were 21–676 cc (median: 94 cc). Post-procedure cyst volumes at last follow-up were 0-40 cc (median: 1 cc). The mean decrease in cyst volume was 95.92 ± 2.86 % in all patients (95.96 ± 3.26 % in Group A and 95.80 ± 6.20 % in Group B). There was no statistically significant difference between the volume reduction rates of Group A and Group B. Only one patient, in Group B, developed a major complication, an abscess. Hospitalization period was 1 day for all patients.ConclusionsFor patients with symptomatic simple hepatic cysts smaller than 500 cc in volume by using puncture, aspiration, injection, and reaspiration (PAIR) technique with only needle, single-session alcohol sclerotherapy of 10 min is a safe and effective procedure with high success rate.

    Tinnitus is a very common symptom, yet the quest for an effective treatment is challenging. Results from several clinical trials support the notion that neuro-music therapy is an effective means to reduce tinnitus distress with short duration and long lasting effect. However, until now, the effectiveness has not been tested in a controlled trial against an active comparator. The trial was designed as two-center, parallel intervention group controlled study with two intervention groups: Counseling (50minute individualized personal instruction) or neuro-music therapy (counseling plus eight 50-minute sessions of individualized music therapy). Data of n=290 patients suffering from chronic tinnitus were analyzed. Outcome measure was the change in Tinnitus Questionnaire Total Scores (TQ) from baseline (admission) to end of treatment. Both treatment groups achieved a statistically relevant reduction in TQ scores, though 66% of patients in the music therapy group attained a clinically meaningful improvement compared to 33% in the counseling group. A binary logistic regression revealed two variables significantly influencing therapy outcome: initial tinnitus score and type of therapy with an OR for the music therapy compared to the counseling of 4.34 (CI 2.33-8.09). Counseling is an appropriate treatment option with well above chance of improvement. The neuro-music therapy outperformed the counseling. This treatment targets the tinnitus sound itself, is short in duration, intrinsically motivating and easy to operate and thus presents a possible complement to the therapeutic spectrum in chronic tinnitus. The trial was registered at the ClinicalTrials.gov registry (ID: NCT01845155). Copyright © 2014 Elsevier Inc. All rights reserved.

    To investigate the effects of pattern scanning laser (Pascal; OptiMedica, Santa Clara, California) multispot panretinal photocoagulation given in a single-session (SS-PRP) vs single-spot multiple-session PRP (MS-PRP) on proliferative diabetic retinopathy (PDR). Single-center, randomized clinical trial of 40 eyes. Proliferative diabetic retinopathy was treated with a 400-mum spot size in 1500 burns given either as Pascal in 20-millisecond SS-PRP or in 3 sessions (100-millisecond MS-PRP) during a 4-week period. Visual acuity, central subfield retinal thickness (CRT), and 24-2 Swedish interactive thresholding algorithm visual fields were recorded at baseline and 4 and 12 weeks. Central subfield retinal thickness, mean deviation, and PDR grade at 12 weeks. There was a significant increase in mean CRT with MS-PRP (22 mum at 4 weeks, 95% CI, -32.25 to -10.75; 20 mum at 12 weeks, 95% CI, -28.75 to -10.82; P Pascal SS-PRP was as effective as MS-PRP in the treatment of PDR. Twenty-millisecond Pascal SS-PRP may be safely and rapidly performed in 1500 burns with a similar efficacy to conventional MS-PRP.

    Background Craving is a core symptom of addictive disorders, such as pathological gambling for example. Over the last decade, several studies have assessed the efficacy of repetitive transcranial magnetic stimulation (rTMS) in the addiction field, which triggers the dorsolateral prefrontal cortex (DLPFC) to decrease craving. The STIMJEU study investigated whether a single session of low-frequency (LF, i.e., 1 Hz) rTMS applied to the right DLPFC reduced cue-induced gambling craving in a sample of treatment-seeking pathological gamblers. Methods Thirty patients received both active and sham rTMS in random order and were blinded to the condition in a within-subject crossover design. Outcome measures included self-reported gambling craving (Visual Analog Scale and Gambling Craving Scale) and physiological measures (heart rate and blood pressure). Results The rTMS sessions were associated with a significant decrease in the gambling urge, regardless of whether the session was active or sham. When controlling cue-induced craving levels, no effects were observed on craving for active rTMS. Overall, rTMS was well-tolerated, and the credibility of the sham procedure was assessed and appeared to be appropriate. Conclusions We failed to demonstrate the specific efficacy of one session of LF rTMS to decrease cue-induced craving in pathological gamblers. A strong placebo-effect and rTMS parameters may partly explain these results. Yet, we are convinced that rTMS remains a promising therapeutic method. Further studies are required to examine its potential effect.

    Research suggests online interventions can have instant impact, however this is yet to be tested with help-seeking adults and in particular those with problem gambling. This study seeks to determine the immediate impact of a single session web-based intervention for problem gambling, and to examine whether sessions evaluated positively by clients are associated with greater improvement. The current study involved 229 participants classified as problem gamblers who agreed to participate after accessing Gambling Help Online between November 2010 and February 2012. Almost half were aged under 35 years of age (45 %), male (57 %) as well as first time treatment seekers (62 %). Participants completed measures of readiness to change and distress both prior to and post-counselling. Following the provision of a single-session of counselling, participants completed ratings of the character of the session (i.e., degree of depth and smoothness) post-counselling. A significant increase in confidence to resist and urge to gamble and a significant decrease in distress (moderate effect size; d = .56 and .63 respectively) was observed after receiving online counselling. A hierarchical regression indicated the character of the session was a significant predictor of change in confidence, however only the sub-scale smoothness was a significant predictor of change in distress. This was the case even after controlling for pre-session distress, session word count and client characteristics (gender, age, preferred gambling activity, preferred mode of gambling, gambling severity, and preferred mode of help-seeking). These findings suggest that single session web-based counselling for problem gambling can have immediate benefits, although further research is required to examine the impact on longer-term outcomes.

    The purpose of this article is to share observations made after performing 90 consecutive micrograft and minigraft megasessions for the treatment of male pattern baldness. Micrograft means grafts with 1 or 2 hairs, minigrafts are those with 3 or 4 hairs, and a megasession is a procedure in which more than 1000 micrografts and minigrafts are inserted in a single session. Between March of 1994 and June of 1996, the author performed 90 consecutive micrograft and minigraft megasessions on 86 men and 4 women ranging from 21 to 67 years of age (average age, 42 years). The surgical team consisted of three surgical assistants and a plastic surgeon. Today, usually between 1500 and 2000 grafts per session are performed in about 4 to 6 hours, with up to 2495 grafts done in a single session. All procedures were done under intravenous sedation and local anesthesia. A donor horizontal ellipse of scalp is harvested from the occipital area; the grafts are made out of it and then inserted through small slits. The procedure has been found to be safe and predictable with natural and aesthetically pleasing results, and there were no serious complications. The only complication found in this group was self-resolving inclusion cysts (ingrown hairs) occurring in 9 of 90 patients (10 percent). Even though the hair density achieved in a single megasession is limited, there is a high level of patient satisfaction: 83 of 85 patients were satisfied (97.65 percent).

    Addiction is mediated in large part by pathological motivation for rewarding, addictive substances, and alcohol-use disorders (AUDs) continue to extract a very high physical and economic toll on society. Compulsive alcohol drinking, where intake continues despite negative consequences, is considered a particular obstacle during treatment of AUDs. Aversion-resistant drives for alcohol have been modeled in rodents, where animals continue to consume even when alcohol is adulterated with the bitter tastant quinine, or is paired with another aversive consequence. Here, we describe a two-bottle choice paradigm where C57BL/6 mice first had 24-h access to 15% alcohol or water. Afterward, they drank quinine-free alcohol (alcohol-only) or alcohol with quinine (100 μM), in a limited daily access (LDA) two-bottle-choice paradigm (2 h/day, 5 days/week, starting 3 h into the dark cycle), and achieved nearly binge-level blood alcohol concentrations. Interestingly, a single, initial 24-h experience with alcohol-only enhanced subsequent quinine-resistant drinking. In contrast, mice that drank alcohol-quinine in the 24-h session showed significantly reduced alcohol-quinine intake and preference during the subsequent LDA sessions, relative to mice that drank alcohol-only in the initial 24-h session and alcohol-quinine in LDA sessions. Thus, mice could find the concentration of quinine we used aversive, but were able to disregard the quinine after a single alcohol-only drinking session. Finally, mice had low intake and preference for quinine in water, both before and after weeks of alcohol-drinking sessions, suggesting that quinine resistance was not a consequence of increased quinine preference after weeks of drinking of alcohol-quinine. Together, we demonstrate that a single alcohol-only session was sufficient to enable subsequent aversion-resistant consumption in C57BL/6 mice, which did not reflect changes in quinine taste palatability. Given the rapid development of quinine

    Early rehabilitation after cardiac surgery aims to prevent immobilization, to reduce the effects of surgery on the respiratory function and to facilitate the recovery of autonomy in the activities of daily living (ADL), after discharge. Nevertheless the optimal perioperative physical therapy care for patients undergoing cardiac surgery is not well established. Moreover, most of the studies monitored peripheral oxygen saturation (SpO2) and heart rate (HR) during surgery or focused only on their recovery after rehabilitation and not on their pathways during a session of exercises. To monitor peripheral oxygen saturation and HR before, during and at the end of a single session of early rehabilitation after cardiac surgery, so testing our protocol's safety. A case series. Department of Cardiothoracic Surgery, inpatients. Forty-eight consecutive inpatients (35 M), mean age 61 years, with cardiovascular disease (CVD), who underwent cardiac surgery. We monitored SpO2%, HR, systemic blood pressure (BP), pain in the thoracic wound (VAS) and rate of perceived exertion (RPE) during the rehabilitation session after weaning from oxygen therapy. During all phases mean SpO2 was 94% (±1.8) and mean HR was 85 bpm (±13.3). Number of desaturation events were 14 in total and mean of % of time with SpO2<90% was 3 (±6.5) during all the rehabilitative session. Moreover, mean BP after reaching the sitting position was 124.7 (±11.9)/78.6 (±8.4) and after ambulation was 131.5 (±11.5)/82.9 (±7.3). The monitoring peripheral oxygen saturation and HR during and not only before and at the end of a standardized early rehabilitation session helped us to ensure the safety of our protocol. Because of its feasibility, safety and reproducibility our rehabilitation treatment has been applied to different types of surgical inpatients in order to limit the negative consequences of immobilization.

    Endotoxins released in the dental root by Gram-negative microorganisms can be neutralized by calcium hydroxide, when this medication is applied inside the root canal for at least seven days. However, several clinical situations demand faster root canal decontamination. Thus, for faster endotoxin neutralization, endodontists are seeking additional treatments. The in vitro study tested whether or not intracanal Nd:YAG laser irradiation would be able to neutralize endotoxin within the human dental root canal in a single session. Twenty-four human teeth with one root were mounted between two chambers. After conventional endodontic treatment, root canals were contaminated with Escherichia coli endotoxin. Then they were irradiated or not (controls) in contact mode with an Nd:YAG laser (1.5 W, 15 Hz, 100 mJ and pulse fluency of 124 J/cm2). The endotoxin activity was measured using the limulus lysate technique and data were statistically compared (p≤0.05). The concentration of active endotoxin measured in the negative control group was significantly lower than that of the positive control group (p=0.04). The concentrations of endotoxin in both irradiated groups were significantly lower than that of the positive control group (p=0.027) and similar to that of negative control group (p=0.20). A single session of intracanal Nd:YAG laser irradiation is able to neutralize endotoxin in the dental root tissues.

    The purpose of this study was to implement and measure the effectiveness of a single-session assertiveness music therapy role playing protocol for psychiatric inpatients. Participants (N=133) were randomly assigned by group to one of three conditions: (a) Assertiveness Music Therapy, (b) No Music Assertiveness, or (c) Music No Assertiveness. Participants in both assertiveness conditions role played a number of different commonly occurring scenarios at an inpatient psychiatric facility and in the community. There were no significant between-group differences in posttest quality of life, locus of control, or other subscales. However, participants in both assertiveness conditions tended to have slightly higher internal locus of control and overall quality of life scores than participants in the music no assertiveness condition. Additionally, the assertiveness music therapy condition had higher attendance rates than the other conditions. A higher percentage of participants from both the assertiveness music therapy and music no assertiveness conditions indicated they thought their session was the most helpful/therapeutic group therapy session in which they had participated; this was not the case for the assertiveness no music condition. Future research is warranted to measure the effects of protocols that can help psychiatric patients generalize skills learned in treatment.

    1995-01-01

    Between September 1987 and September 1993, 88 patients with oesophageal cancer were treated by a single session of intraluminal brachytherapy of 15 Gy prescribed at 1 cm distance from the central axis, using MDR 137 Cs (n 51) during the first part of the study and HDR 192 Ir (n = 37) during the second part of the study. All patients were regarded as inoperable. Improvement of dysphagia, assessed 4-6 weeks after treatment, was noted in 50 of 75 (67%) evaluable patients, whereas swallowing ability was completely restored in 47% of them. Relapse of dysphagia occurred in 28 (37%) patients during follow-up. Additional palliative treatment consisted of endoprosthesis in 14 (19%), a second course of brachytherapy in 13 (17%), one or more dilatations only in 11 (15%) and laser treatment in four (5%) patients. One non-fatal haemorrhage and five fistulae occurred, all in the presence of tumour. Two severe ulcerations without evidence of tumour were noted, both managed by combined curative treatment. The median survival of the group investigated was 5.5 months. An exophytic, non-circular growth pattern was associated with a better response. In a multivariate analysis the presence of distant metastases (p = 0.0028), weight loss (p = 0.0051) and an exophytic growth pattern (p = 0.0199) were associated with a worse survival. The present data indicate that a single session of ILB is appropriate in the palliation of dysphagia in patients with inoperable oesophagal cancer showing bad prognostic signs. Up to now there has been no clear evidence for benefit of addition of ERT

  11. Auditory Cortex tACS and tRNS for Tinnitus: Single versus Multiple Sessions

    2014-01-01

    Full Text Available Tinnitus is the perception of a sound in the absence of an external acoustic source, which often exerts a significant impact on the quality of life. Currently there is evidence that neuroplastic changes in both neural pathways are involved in the generation and maintaining of tinnitus. Neuromodulation has been suggested to interfere with these neuroplastic alterations. In this study we aimed to compare the effect of two upcoming forms of transcranial electrical neuromodulation: alternating current stimulation (tACS and random noise stimulation (tRNS, both applied on the auditory cortex. A database with 228 patients with chronic tinnitus who underwent noninvasive neuromodulation was retrospectively analyzed. The results of this study show that a single session of tRNS induces a significant suppressive effect on tinnitus loudness and distress, in contrast to tACS. Multiple sessions of tRNS augment the suppressive effect on tinnitus loudness but have no effect on tinnitus distress. In conclusion this preliminary study shows a possibly beneficial effect of tRNS on tinnitus and can be a motivation for future randomized placebo-controlled clinical studies with auditory tRNS for tinnitus. Auditory alpha-modulated tACS does not seem to be contributing to the treatment of tinnitus.

    One-Session Treatment (OST) for specific phobias has been shown to be effective in reducing phobia severity; however, the effect of different types of co-occurring anxiety disorders on OST outcomes is unknown. The present study examined (1) the effects of co-occurring generalized anxiety disorder (GAD), social anxiety disorder (SAD), or another non-targeted specific phobia (OSP) on the efficacy of OST for specific phobias, and (2) the effects of OST on these co-occurring disorders following treatment. Three groups of 18 youth (7-15 years) with a specific phobia and comorbid GAD, SAD, or OSP were matched on age, gender, and phobia type. Outcome measures included diagnostic status and severity, and clinician rated improvement. All groups demonstrated an improvement in their specific phobia following treatment. Treatment was equally effective regardless of co-occurring anxiety disorder. In addition, comorbid anxiety disorders improved following OST; however, this effect was not equal across groups. The SAD group showed poorer improvement in their comorbid disorder than the GAD group post-treatment. However, the SAD group continued to improve and this differential effect was not evident six-months following treatment. The current study sample was small, with insufficient power to detect small and medium effect sizes. Further, the sample only included a portion of individuals with primary GAD or SAD, which may have attenuated the findings. The current study demonstrated that co-occurring anxiety disorders did not interfere with phobia treatment. OST, despite targeting a single specific phobia type, significantly reduced comorbid symptomatology across multiple anxiety disorders. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Developments in working alliance theory posit that the therapist's attention to fluctuations in the alliance throughout treatment is crucial. Accordingly, researchers have begun studying the alliance as a time-varying mechanism of change rather than as a static moderator. However, most studies to date suffer from bias owing to the nonindependence of error term and predictors (endogeneity). Patients with major depressive disorder (N = 84) from a randomized trial comparing cognitive-behavioral therapy with interpersonal psychotherapy filled out the Beck Depression Inventory-II before each session. After each session, patients and therapists filled out the Working Alliance Inventory short forms. Data were analyzed using the generalized method of moments for dynamic panel data, a method commonly applied in econometrics to eliminate endogeneity bias. Improvement of the alliance predicted significant reduction of depressive symptoms by the next session (patient rating: b = -4.35, SE = 1.96, p = .026, 95% confidence interval [CI] [-8.19, -0.51]; therapist rating: b = -4.92, SE = 1.84, p = .008, 95% CI [-8.53, -1.31]). In addition, there was a significant delayed effect on the session after the next (patient rating: b = -3.25, SE = 1.20, p = .007, 95% CI [-5.61, -0.89]; therapist rating: b = -5.44, SE = 1.92, p = .005, 95% CI [-9.20, -1.68]). If the quality of patient-therapist alliance is improved in a given treatment session, depressive symptoms will likely decrease by the next session. The most important limitation of this study is its relatively small sample size. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Several studies have demonstrated that one exercise session (ES) on a cycloergometer or ergometric treadmill causes a reduction in blood pressure (BP). However, there are few similar studies on walking, which is the exercise modality most available to the elderly. We investigated the immediate and 24-h effects of walking on BP in independent, community-living elderly individuals. Volunteers participated in a single ES and resting control session (CS). Before and after each session, BP was measured by auscultatory and oscillometric methods. After each session, 24-h ambulatory blood pressure monitoring was conducted. An accelerometer was installed 48 h before the sessions and left in place for 5 days. The mean volunteer age was 67.7±3.5 years; 11 were hypertensive patients under treatment, and 12 were normotensive. In the total sample, there were immediate 14mm Hg and 12 mm Hg reductions in systolic BP (SBP) after the ES according to the auscultatory and oscillometric methods, respectively. Diastolic BP (DBP) was reduced by 4 mm Hg after the ES according to both methods. SBP during wakefulness and sleep and DBP during wakefulness were lower after the ES than after the CS (Psleep were determined individually (variable-time pattern) using data from the activity monitors and provided by the volunteers. The variable-time pattern was more effective in detecting reductions in BP than the fixed-time pattern.

    To clarify the effect of single-session multivessel percutaneous coronary intervention (PCI) strategy relative to the staged multivessel strategy on clinical outcomes in patients with stable coronary artery disease (CAD) or non-ST-elevation acute coronary syndrome. In the Coronary REvascularisation Demonstrating Outcome Study in Kyoto PCI/coronary artery bypass grafting registry cohort-2, there were 2018 patients who underwent elective multivessel PCI. Primary outcome measure was composite of all-cause death, myocardial infarction and stroke at 5-year follow-up. Single-session multivessel PCI and staged multivessel PCI were performed in 707 patients (35.0%) and 1311 patients (65.0%), respectively. The cumulative 5-year incidence of and adjusted risk for the primary outcome measure were not significantly different between the single-session and staged groups (26.7% vs 23.0%, p=0.45; HR 0.91, 95% CI 0.72 to 1.16, p=0.47). The 30-day incidence of all-cause death was significantly higher in the single-session group than in the staged group (1.1% vs 0.2%, p=0.009). However, the causes of death in 11 patients who died within 30 days were generally not related to the procedural complications, but related to the serious clinical status before PCI. For the subgroup analyses including age, gender, extent of CAD, severe chronic kidney disease and heart failure, there was no significant interaction between the subgroup factors and the effect of the single-session strategy relative to the staged strategy for the primary outcome measure. The single-session multivessel PCI strategy was associated with at least comparable 5-year clinical outcomes compared with the staged multivessel PCI, although the prevalence of the single-session strategy was low in the present study. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    The Institute of Medicine (IOM) reported that chronic pain affects about 100 million U.S. adults, with chronic low back pain (CLBP) cited as the most prevalent type. Pain catastrophizing is a psychological construct shown to predict the development and trajectory of chronic pain and patient response to pain treatments. While effective treatment for pain catastrophizing typically includes eight-session groups of cognitive behavioral therapy (CBT), a single-session targeted treatment class yielded promising results which, if replicated and extended, could prove to efficiently and cost-effectively reduce pain catastrophizing. In this trial, we seek to determine the comparative efficacy of this novel single-session pain catastrophizing class to an eight-session course of pain CBT and a single-session back pain health education class. We will also explore the psychosocial mechanisms and outcomes of pain catastrophizing treatment. In this trial we will randomize 231 individuals with CLBP to one of three treatment arms: (1) pain-CBT (eight weekly 2-h group sessions with home exercises and readings); (2) a single 2-h pain catastrophizing class; or (3) a single 2-h back pain health education class (active control). For the primary outcome of pain catastrophizing, the trial is designed as a non-inferiority test between pain-CBT and the single-session pain catastrophizing class, and as a superiority test between the single-session pain catastrophizing class and the health education class. Team researchers masked to treatment assignment will assess outcomes up to six months post treatment. If the single-session targeted pain catastrophizing class is found to be an effective treatment for patients with CLBP, this low cost and low burden treatment could dismantle many of the current barriers and burdens of effective pain care. Further, elucidation of the mechanisms of pain catastrophizing treatments will facilitate future research on the topic as well as further development and

    2015-07-01

    The purpose of this study was to conduct a meta-analysis summarizing the effectiveness of brief, single-session interventions to reduce alcohol use among heavy drinking college students. A comprehensive literature search identified 73 studies comparing the effects of single-session brief alcohol intervention with treatment-as-usual or no-treatment control conditions on alcohol use among heavy drinking college students. Random-effects meta-analyses with robust variance estimates were used to synthesize 662 effect sizes, estimating the average overall effect of the interventions and the variability in effects across a range of moderators. An overall mean effect size of ḡ = 0.18, 95% CI [0.12, 0.24] indicated that, on average, single-session brief alcohol interventions significantly reduced alcohol use among heavy drinking college students relative to comparison conditions. There was minimal variability in effects associated with study method and quality, general study characteristics, participant demographics, or outcome measure type. However, studies using motivational enhancement therapy/motivational interviewing (MET/MI) modalities reported larger effects than those using psychoeducational therapy (PET) interventions. Further investigation revealed that studies using MET/ MI and feedback-only interventions, but not those using cognitive-behavioral therapy or PET modalities, reported average effect sizes that differed significantly from zero. There was also evidence that long-term effects were weaker than short-term effects. Single-session brief alcohol interventions show modest effects for reducing alcohol consumption among heavy drinking college students and may be particularly effective when they incorporate MET/MI principles. More research is needed to directly compare intervention modalities, to develop more potent interventions, and to explore the persistence of long-term effects.

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

    PURPOSE: The primary purpose of this study was to investigate whether a single session of spinal manipulation (SM) increases strength and cortical drive in the lower limb (soleus muscle) of elite Taekwondo athletes. METHODS: Soleus-evoked V-waves, H-reflex and maximum voluntary contraction (MVC......) of the plantar flexors were recorded from 11 elite Taekwondo athletes using a randomized controlled crossover design. Interventions were either SM or passive movement control. Outcomes were assessed at pre-intervention and at three post-intervention time periods (immediate post, post 30 min and post 60 min......). A multifactorial repeated measures ANOVA was conducted to assess within and between group differences. Time and session were used as factors. A post hoc analysis was carried out, when an interactive effect was present. Significance was set at p ≤ 0.05. RESULTS: SM increased MVC force [F(3,30) = 5.95, p

    The effects of sleep deprivation on physical performance are well documented, but data on the consequence of sleep deprivation on recovery from exercise are limited. The aim was to compare cyclists' recovery from a single bout of high-intensity interval training (HIIT) after which they were given either a normal night of sleep (CON, 7.56 ± 0.63 h) or half of their usual time in bed (DEP, 3.83 ± 0.33 h). In this randomized cross-over intervention study, 16 trained male cyclists (age 32 ± 7 years), relative peak power output (PPO 4.6 ± 0.7 W kg -1 ) performed a HIIT session at ±18:00 followed by either the CON or DEP sleep condition. Recovery from the HIIT session was assessed the following day by comparing pre-HIIT variables to those measured 12 and 24 h after the session. Following a 2-week washout, cyclists repeated the trial, but under the alternate sleep condition. PPO was reduced more 24 h after the HIIT session in the DEP (ΔPPO -0.22 ± 0.22 W kg -1 ; range -0.75 to 0.1 W kg -1 ) compared to the CON condition (ΔPPO -0.05 ± 0.09 W kg -1 , range -0.19 to 0.17 W kg -1 , p = 0.008, d = -2.16). Cyclists were sleepier (12 h: p = 0.002, d = 1.90; 24 h: p = 0.001, d = 1.41) and felt less motivated to train (12 h, p = 0.012, d = -0.89) during the 24 h recovery phase when the HIIT session was followed by the DEP condition. The exercise-induced 24 h reduction in systolic blood pressure observed in the CON condition was absent in the DEP condition (p = 0.039, d = 0.75). One night of partial sleep deprivation impairs recovery from a single HIIT session in cyclists. Further research is needed to understand the mechanisms behind this observation.

    Simple renal cysts are rare in children and managed conservatively unless symptomatic. To demonstrate the efficacy and long-term results of single-session ethanol sclerotherapy in symptomatic simple renal cysts in children. Three simple renal cysts in three children (age 1, 5 and 16 years) were included in the study. Indications for treatment were flank pain (n=1), hypertension (n=1), and increasing cyst size and urinary tract infection (n=1). The mean follow-up period was 5.5 years (range 3-7 years). The procedures were performed with the guidance of US and fluoroscopy and under IV sedation. After the cystogram, 95% ethanol with a volume of 40% of the cyst volume (but not more than 100 ml) was used as the sclerosing agent. Two cysts disappeared completely, while the volume reduction was 99% for the third cyst at the end of the first year. CT demonstrated calcification of the cyst without an enhancing soft-tissue component in the third one 7 years after sclerotherapy. After the procedures, hypertension and pain resolved without any medication. There were no complications during the procedures or during follow-up. Cytological examination was unremarkable in all patients. Percutaneous treatment of symptomatic simple renal cysts in children with single-session ethanol sclerotherapy is a safe, effective and minimally invasive procedure. Calcification owing to sclerotherapy can be observed on follow-up. (orig.)

    The present study evaluated the effectiveness of a modified One Session Treatment (OST), which included an e-therapy homework maintenance program over 4 weeks for Blood-Injection-Injury (BII) phobia in children and adolescents. Using a single case, non-concurrent multiple-baseline design, 24 children and adolescents (8-18 years; 7 males, 17 females) with a primary diagnosis of BII phobia were randomly assigned to a one, two or three week baseline prior to receiving OST. Primary outcome measures included diagnostic severity, diagnostic status, and child and parent fear ratings. Secondary outcome measures included avoidance during behavioural avoidance tasks (BAT), global functioning and self and parent reported anxiety, fear and depression. Efficacy was assessed at post-treatment, 1-month, and 3-month follow-up. BII symptoms and diagnostic severity remained relatively stable during the baseline periods and then significantly improved following implementation of the intervention. Treatment response was supported by changes across multiple measures, including child, parent and independent clinician ratings. At post-treatment 8 of the 24 (33.33%) children were BII diagnosis free. Treatment gains improved at follow-ups with 14 (58.33%) children diagnosis free at 1-month follow-up and 15 (62.5%) diagnosis free at 3-month follow-up. Preliminary findings support the effectiveness of a modified OST approach for BII phobic youth with treatment outcomes improving over follow-up intervals. Copyright © 2015 Elsevier Ltd.

    [Purpose] Robot-assisted gait training (RAGT) using Hybrid Assistive Limb (HAL, CYBERDYNE) was previously reported beneficial for stroke and spinal cord injury patients. Here, we investigate the immediate effect of a single session of RAGT using HAL on gait function for cerebral palsy (CP) patients. [Subjects and Methods] Twelve patients (average age: 16.2 ± 7.3 years) with CP received a single session of RAGT using HAL. Gait speed, step length, cadence, single-leg support per gait cycle, hip and knee joint angle in stance, and swing phase per gait cycle were assessed before, during, and immediately after HAL intervention. [Results] Compared to baseline values, single-leg support per gait cycle (64.5 ± 15.8% to 69.3 ± 12.1%), hip extension angle in mid-stance (149.2 ± 19.0° to 155.5 ± 20.1°), and knee extension angle in mid-stance (137.6 ± 20.2° to 143.1 ± 19.5°) were significantly increased immediately after intervention. Further, the knee flexion angle in mid-swing was significantly decreased immediately after treatment (112.0 ± 15.5° to 105.2 ± 17.1°). Hip flexion angle in mid-swing also decreased following intervention (137.2 ± 14.6° to 129.7 ± 16.6°), but not significantly. Conversely, gait speed, step length, and cadence were unchanged after intervention. [Conclusion] A single-time RAGT with HAL improved single-leg support per gait cycle and hip and knee joint angle during gait, therapeutically improving gait function in CP patients.

    This study aims to propose and validate the tethered swimming lactate minimum test (TSLacmin) estimating aerobic and anaerobic capacity in one single test session, using force as measurement parameter. 6 male and 6 female young swimmers (age=15.7±1.1 years; height=173.3±9.5 cm; weight=66.1±9.5 kg) performed 4 sessions comprising i) an all-out 30 s test and incremental test (TSLacmin); ii) 30 min of tethered swimming at constant intensity (2 sessions); iii) free-swimming time trials used to calculate critical velocity. Tethered swimming sessions used an acquisition system enabling maximum (Fmax) and mean (Fmean) force measurement and intensity variation. The tethered all-out test lasting 30 s resulted in hyperlactatemia of 7.9±2.0 mmol·l -1 . TSLacmin presented a 100% success applicability rate, which is equivalent to aerobic capacity in 75% of cases. TSLacmin intensity was 37.7±7.3 N, while maximum force in the all-out test was 105±27 N. Aerobic and anaerobic TSLacmin parameters were significantly related to free-swimming performance (r=-0.67 for 100 m and r=-0.80 for 200 m) and critical velocity (r=0.80). TSLacmin estimates aerobic capacity in most cases, and both aerobic and anaerobic force parameters are well related to critical velocity and free swimming performance. © Georg Thieme Verlag KG Stuttgart · New York.

    The primary purpose of this study was to investigate whether a single session of spinal manipulation (SM) increases strength and cortical drive in the lower limb (soleus muscle) of elite Taekwondo athletes. Soleus-evoked V-waves, H-reflex and maximum voluntary contraction (MVC) of the plantar flexors were recorded from 11 elite Taekwondo athletes using a randomized controlled crossover design. Interventions were either SM or passive movement control. Outcomes were assessed at pre-intervention and at three post-intervention time periods (immediate post, post 30 min and post 60 min). A multifactorial repeated measures ANOVA was conducted to assess within and between group differences. Time and session were used as factors. A post hoc analysis was carried out, when an interactive effect was present. Significance was set at p ≤ 0.05. SM increased MVC force [F(3,30) = 5.95, p < 0.01], and V-waves [F(3,30) = 4.25, p = 0.01] over time compared to the control intervention. Between group differences were significant for all time periods (p < 0.05) except for the post60 force measurements (p = 0.07). A single session of SM increased muscle strength and corticospinal excitability to ankle plantar flexor muscles in elite Taekwondo athletes. The increased MVC force lasted for 30 min and the corticospinal excitability increase persisted for at least 60 min.

    Full Text Available Objective: Objective: To compare the success rate between the one session and two session indirect pulp capping of asymptomatic pulpitis for 1 year after the treatment was performed in children with different caries risk. Material and Methods: The children and the teeth were selected according to certain criteria for inclusion in the study. According to that, 72 children with low, moderate and high caries risk were included and 131 teeth with asymptomatic pulpitis were treated. The clinical protocols for indirect pulp capping (IPC in one session and two sessions were defined. The review appointments were performed 6 and 12 months after the treatment using certain clinical and radiographic criteria which defined success or post-treatment complications. The results are statistically analysed using One Sided Exact Two-Proportion Test with 95% Significance level (5% risk of type I error. Results: The statistical test showed that between the compared success rates of the one session and two sessions IPC, on the 6th and 12th month, there wasn’t a significant difference (p>0.05. This was valid for every one of the examined groups of patients (p>0. 05. This proves that there is no difference in the success rates of treatment of pulpitis in primary teeth using one or two sessions. Conclusions: The results about the success of treatment of asymptomatic pulpitis in primary teeth during one or two sessions have confirmed the results showed in other current studies. Our study has confirmed (clinically and radiographically the success of both techniques and we have concluded that in children with high caries risk, more appropriate technique is the one performed in two sessions. Treatment in one session is recommended in children with low or moderate caries risk.

    Objective To evaluate the stone hardness in predicting the need for single or two sessions of retrograde intrarenal surgery (RIRS) for renal pelvis stones of 2–3 cm in size. Material and methods Ninety-six patients (64 male and 32 female) with only renal stones (2.5±0.3 cm) underwent RIRS using flexible 7.5 Fr ureteroscope (FURS). The stone hardness was evaluated by preoperative non-contrast computed tomography (NCCT). The patients were divided into two groups based on stone hardness: Group I (n=54) (hard stones - Hounsfield Unit (HU) >1000) and group II (n=42) (not hard stone - HU <1000). The stone-free rate, the operative time, any intra or postoperative complications and the need for second sessions of RIRS were evaluated. Results All stones were successfully accessed. Intraoperative complications were not reported. The initial stone-free rate was 40% in Group I and 95% in Group II after a single session (p=0.01). A second session FURS was needed in 32 cases of Group I (40%) where postoperative CT showed significant residual stone fragments of 6±2 mm, and stone-free rate up to 100 percent. On the contrary only 2 cases from Group II underwent second session FURS (p=0.01). The operative times were 75±15 minutes in Group I and 55±13 minutes in Group II (p<0.01). Six patients (4 in group I and 2 in group II) had postoperative high-grade fever (Clavien Grade II). Conclusion Stone hardness had a significant impact on the decision of performing single versus two sessions of FURS for renal pelvic stones of 2–3 cm rather than the stone size alone. PMID:28717539

    Irisin is a recently identified exercise-induced hormone that increases energy expenditure, at least in rodents. The main purpose of this study was to test the hypothesis that Irisin increases acutely in blood after singular sessions of intense endurance exercise (END) and heavy strength training (STR). Secondary, we wanted to explore the relationship between body composition and exercise-induced effects on irisin, and the effect of END and STR on muscular expression of the irisin gene FNDC5. Nine moderately trained healthy subjects performed three test days using a randomized and standardized crossover design: one day with 60 minutes of END, one day with 60 minutes of STR, and one day without exercise (CON). Venous blood was sampled over a period of 24h on the exercise days. Both END and STR led to transient increases in irisin concentrations in blood, peaking immediately after END and one hour after STR, before gradually returning to baseline. Irisin responses to STR, but not END, showed a consistently strong negative correlation with proportions of lean body mass. Neither END nor STR affected expression of FNDC5, measured 4h after training sessions, though both protocols led to pronounced increases in PGC-1α expression, which is involved in transcriptional control of FNDC5. The results strongly suggest that single sessions of intense endurance exercise and heavy strength training lead to transient increases in irisin concentrations in blood. This was not accompanied by increased FNDC5 expression, measured 4h post-exercise. The results suggest that irisin responses to resistance exercise are higher in individuals with lower proportions of lean body mass.

    This case study describes a single group psychotherapy session of six individuals suffering from schizophrenia or schizoaffective illness, which was characterized by numerous manifestations of fragile Ego boundaries. Based on these illustrations of fragile Ego boundaries, we explore some of the group's core therapeutic actions against psychosis. We discuss how the group (1) provides access to a structuring auxiliary Ego, (2) acts as a containing object by establishing firm boundaries and by mentalizing patients' psychotic productions, and (3) may become a solid object representation introjected by individuals wrestling with porous Ego boundaries and a poor sense of self. We conclude that, in addition to the known role of group therapy in increasing mature defenses, developing insight and providing social support, the group promotes healthier Ego boundaries, and eventually improves self-differentiation, and also tolerance to interpersonal proximity. This case study clarifies group therapy dynamics with individuals suffering from psychosis.

    Dual-process models propose that impulsive behavior plays a key role in the development and maintenance of maladaptive eating patterns. Research outside the eating domain suggests that approach avoidance training, a paradigm which aims to modify automatic behavioral dispositions toward critical stimuli, is an effective tool to weaken unhealthy impulses. The present research tested the effectiveness of approach avoidance training in the eating domain. We conducted three single session studies with varying methodologies in a normal-weight female student population (total N = 258), in which one group was always trained to avoid pictures of unhealthy food and to approach pictures of healthy food or neutral objects. We found no conclusive evidence that approach avoidance training can change participants' implicit and explicit food preferences and eating behavior. We discuss the potential and the limitations of approach avoidance training in the eating domain and provide suggestions for future research avenues. Copyright © 2014 Elsevier Ltd.

    Previous research on maternal hemodynamic responses to a single exercise session during pregnancy is sparse, especially considering immediate responses to resistance exercise. The aim of the study was to examine blood pressure, heart rate, body temperature, and Rating of Perceived Exertion in healthy pregnant women during single sessions of continuous submaximal exercise in pregnancy week 21. A cross-over design was used. Twenty healthy pregnant women from four prenatal clinics in Gothenburg, Sweden, were included. On day 1, the women did 30 min of aerobic exercise and on day 3 they did 30 min of resistance exercise. Blood pressure, heart rate, and Rating of Perceived Exertion were measured after 15 and 30 min of exercise. After 15 and 30 min of exercise, there was a significant increase in systolic blood pressure and heart rate (p aerobic exercise (p = 0.01) than resistance exercise (p = 0.03). Resistance exercise was perceived as more intense than aerobic exercise after 15 min (p = 0.02) and 30 min (p = 0.001) of exercise. Five minutes after completing the exercise, blood pressure quickly reverted to normal although heart rate was still increased (p = 0.001). There was no correlation between heart rate and Rating of Perceived Exertion (rs  = 0.05-0.43). Maternal hemodynamic responses were essentially the same, regardless of whether the exercise was submaximal aerobic or resistance exercise, although resistance exercise was perceived as more intense. Aerobic and resistance exercise corresponding to "somewhat hard" seems to have no adverse effect with regard to maternal hemodynamic responses in healthy pregnancy. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    Objective Examine the efficacy of a parent-augmented One Session Treatment (A-OST) in treating specific phobias (SP) in youth by comparing this novel treatment to child-focused OST, a well-established treatment. Method A total of 97 youth (ages 6–15, 51.5% female, 84.5% white) who fulfilled diagnostic criteria for SP were randomized to either A-OST or OST. SPs were assessed with semi-structured diagnostic interviews, clinician improvement ratings, and parent and child improvement ratings. In addition, measures of treatment satisfaction and parental self-efficacy were obtained. Blind assessments were completed pretreatment, post-treatment, and 1-month and 6-months following treatment. Analyses were undertaken using mixed models. In addition, gender, age, internalizing/externalizing problems, parent overprotection, and parent anxiety were examined as potential predictors and moderators of treatment outcome. Results Both treatment conditions produced similar outcomes with approximately 50% of youth in both treatments diagnosis free and judged to be much or very much improved at post-treatment and 1-month follow up. At 6-month follow up, however, the treatments diverged with OST resulting in marginally superior outcomes to A-OST, contrary to predictions. Only age of child predicted treatment outcome across the two treatments (older children did better); unexpectedly, none of the variables moderated treatment outcomes. Conclusions Parent augmentation of OST produced no appreciable gains in treatment outcomes. Directions for future research are highlighted. PMID:25645164

    The objective of this study was to evaluate the performances of the Storz Modulith SL20 lithotriptor. Fifty patients with a total of 52 renal (31) or ureteric (21) stones were treated, in a single session, between June and October 1993. The mean stone diameter was 7.9 mm. All patients were reviewed after 3 months. The complete success rate, with radiological cure, was 65% at 3 months. The partial success rate, defined as fragmentation of the stone with persistence of residual fragments less than 3 mm in diameter, not requiring further treatment, was 12% at 3 months. The failure rate at 3 months was 23%. The commonest complication was renal colic in 12 patients (24%). Two patients developed an extrarenal haematoma. The Modulith SL20 possesses a good detection system: firing is well tolerated under minimal analgesia. Our success rates are slightly lower than those obtained by other teams using the same apparatus.

  1. Single-session emotion regulation skills training to reduce aggression in combat veterans: A clinical innovation case study.

    2016-05-01

    Posttraumatic stress disorder (PTSD) is common among returning veterans, and aggression frequently co-occurs with PTSD. Veterans with PTSD most commonly engage in impulsive aggression, or aggression that is emotionally charged, unplanned, and uncontrolled, rather than premeditated aggression, which is planned and controlled. Previous research demonstrated a variety of emotions can result in aggression, rather than the traditional conceptualization that only anger leads to aggression. In a veteran sample, deficiencies in the ability to regulate emotions (emotion dysregulation) mediated the relationship between PTSD and impulsive aggression. These results suggest that teaching veterans with PTSD and impulsive aggression how to regulate emotions may decrease aggression. The cases presented illustrate the use of an innovative, single-session emotion regulation treatment for combat veterans with PTSD. Two cases are presented to generate hypotheses on who might benefit from this treatment in the future. The two male veterans treated with this protocol differed in how frequently they used the emotion regulation skills after the treatment and in their treatment outcomes. Teaching veterans how to regulate their emotions in a condensed time frame may be beneficial for certain veterans, and further research on this brief treatment is warranted.

    This literature review compares the endodontic treatment in one or more appointments on the healing of periapical lesions and the occurrence of postoperative pain and flare-ups. It turns out that the root canal treatment completed in one session has many advantages and may he considered the prime option in the majority of clinical cases.

    A number of studies have investigated the efficacy of several repetitions of proprioceptive neuromuscular facilitation stretching (PNF) and static stretching (SS). However, there is limited research comparing the effects of a single bout of these stretching maneuvers. The aim of this study was to compare the effectiveness of a single bout of a therapist-applied 30-second SS vs. a single bout of therapist-applied 6-second hamstring (agonist) contract PNF. Forty-five healthy subjects between the ages of 21 and 35 were randomly allocated to 1 of the 2 stretching groups or a control group, in which no stretching was received. The flexibility of the hamstring was determined by a range of passive knee extension, measured using a universal goniometer, with the subject in the supine position and the hip at 90° flexion, before and after intervention. A significant increase in knee extension was found for both intervention groups after a single stretch (SS group = 7.53°, p < 0.01 and PNF group = 11.80°, p < 0.01). Both interventions resulted in a significantly greater increase in knee extension when compared to the control group (p < 0.01). The PNF group demonstrated significantly greater gains in knee extension compared to the SS group (mean difference 4.27°, p < 0.01). It can be concluded that a therapist applied SS or PNF results in a significant increase in hamstring flexibility. A hamstring (agonist) contract PNF is more effective than an SS in a single stretching session. These findings are important to physiotherapists or trainers working in clinical and sporting environments. Where in the past therapists may have spent time conducting multiple repetitions of a PNF and an SS, a single bout of either technique may be considered just as effective. A key component of the study methodology was the exclusion of a warm-up period before stretching. Therefore, the findings of efficacy of a single PNF are of particular relevance in sporting environments and busy clinical

    It is evidently shown that colour has physical, psychological and sociological effects on human beings. There are many studies showing the effects of colours on brain activity. Colour preferences may change from childhood to adulthood and are significantly different in various age groups. The aim of this study was to evaluate the adults and children in their preference for mouthrinses in various colours under stress condition during a dental treatment session. 240 adults and 263 children were included in the study. Three transparent cups were filled with water, two of which were coloured green/pink rinsing by dissolving a tablet in the water. Cups were placed near the dental unit. During dental treatment sessions, patients were told to rinse their mouth with whichever cup they preferred. Preferred colour of cup, gender and age of patient, number of sessions were recorded. Data were statistically analysed by SPSS 15.0 programme and chi-square tests. Half of all cases preferred water. In adults, while females statistically significantly preferred water, males chose cups with coloured contents (pcoloured contents in multi-dental treatment sessions, children regularly preferred water (pgender and colours of cups affected choices made by adults and children. Female adults and children were not interested in trying colourful mouthrinses, while male adults were curious about trying colourful mouthrinses during dental treatment sessions under stress condition.

    This study investigated the extent to which bilingual counselors initiated informal discussions about topics that were unrelated to the treatment of their monolingual Spanish-speaking Hispanic clients in a National Institute on Drug Abuse Clinical Trial Network protocol examining the effectiveness of motivational enhancement therapy (MET). Session audiotapes were independently rated to assess counselor treatment fidelity and the incidence of informal discussions. Eighty-three percent of the 23 counselors participating in the trial initiated informal discussions at least once in one or more of their sessions. Counselors delivering MET in the trial initiated informal discussion significantly less often than the counselors delivering standard treatment. Counselors delivering standard treatment were likely to talk informally the most when they were ethnically non-Latin. Additionally, informal discussion was found to have significant inverse correlations with client motivation to reduce substance use and client retention in treatment. These results suggest that informal discussion may have adverse consequences on Hispanic clients’ motivation for change and substance abuse treatment outcomes and that maintaining a more formal relationship in early treatment sessions may work best with Hispanic clients. Careful counselor training and supervision in MET may suppress the tendency of counselors to talk informally in sessions. PMID:20817381

    This study was designed to provide a better understanding of how a single neurodevelopmental treatment (NDT) session affects sit-to-stand (STS) movements in children with cerebral palsy (CP). Eight children with spastic diplegia and five typically developing children, aged 4-6 years, participated in this study. The CP participants performed STS movements immediately before and after a 40-min NDT session. Using a three-dimensional, four-camera analysis system, angular movements involving the hip, knee and ankle joints of the participants were obtained. During forward tilt of the trunk, the maximum and final angles after the NDT session significantly decreased compared with those before the session (p spastic diplegia, with limited ability to independently transfer from a sitting position, and dependent on a wheelchair for mobility experience obstacles to enhanced activities of daily life and social participation. A single neurodevelopmental treatment session would enable children with spastic diplegia to perform sit-to-stand movements more efficiently, with selective muscle control. Understanding how a single neurodevelopmental treatment session affects sit-to-stand movements in children with spastic diplegia is invaluable for therapists planning more efficient therapeutic programs and may enable children with spastic diplegia to develop improved mobility.

    Spasticity is a common, serious symptom after stroke. Extracorporeal shock wave therapy (ESWT) has been suggested for the treatment of muscle spasticity. To investigate the effects of ESWT on post stroke wrist flexor spasticity. Fifteen patients with poststroke wrist flexor spasticity (12 male and 3 female with a mean age of 54 years) were enrolled. Patients received 1 sham ESWT followed by 1 active ESWT 1 week later. The outcome measures were the Modified Modified Ashworth Scale (MMAS), the Hmax/Mmax ratio, and the Brunnstrom motor recovery stage. The sham ESWT had not effects on the outcome measures. After active ESW, the MMAS scores of spasticity and the Hmax/Mmax ratio improved. The improvements were maintained 5 weeks after active ESWT. No significant improvements were observed for the motor recovery after sham or active ESWT. In adult patients after stroke, a single session of active ESWT resulted in significant improvement in the wrist flexor spasticity and alpha motor neuron excitability.

    Purpose To examine the effects of radial extracorporeal shockwave therapy (rESWT) on plantarflexor spasticity after stroke. Method Twelve patients with stroke were randomly included for this prospective, single-blind clinical trial. Patients received one rESWT session (0.340 mJ/mm 2 , 2000 shots) on plantarflexor muscle. The Modified Modified Ashworth Scale (MMAS), H-reflex tests, ankle range of motion (ROM), passive plantarflexor torque (PPFT) and timed up and go test (TUG) were measured at baseline (T 0 ), immediately after treatment (T 1 ) and one hour after the end of the treatment (T 2 ). Results Patients had improved the MMAS scores for both the gastrocnemius and the soleus muscles, active and passive ROM, PPFT and TUG over time after rESWT. For the PPFT, it was greater at high velocity than at low velocity, and there was a significant three-way interaction between time, knee position (extended/flexed) and velocity (low/high). The H-reflex latency had decreased at T 1 , but there was no significant effect on H max /M max ratio. Conclusions The rESWT improved plantarflexor spasticity, and the effects sustained for one hour, whereas it was not effective in improving spinal excitability. Implications for Rehabilitation One session radial extracorporeal shock wave therapy (rESWT) is safe and effective in improving post stroke plantarflexor spasticity, ankle active and passive range of motion, passive torque, and walking capability. The spasticity scores improved for both the gastrocnemius and the soleus muscles and persisted one hour after rESWT. The magnitude of resistive plantarflexor passive torque in the knee extended position and high velocity was larger over time suggesting greater gastrocnemius spasticity than soleus. The rESWT had no significant effects on alpha motorneuron excitability.

    Full Text Available To obtain preliminary safety and efficacy data on intravenous (IV administration of infliximab (IFX and ferric carboxymaltose (FCM to inflammatory bowel disease (IBD patients in a single treatment session.A two-phase non-interventional, observational, prospective pilot study was performed to evaluate safety and efficacy of FCM given immediately after IFX. IBD patients were recruited consecutively in the outpatient clinic in two groups. Control group patients (n = 12 received FCM on a separate day from IFX. Subsequently, single-session group patients (n = 33 received FCM after IFX on the same day. All patients received 5mg/kg IFX and 1000mg FCM for iron-restricted anemia (IRA or 500mg FCM for iron deficiency without anemia. Safety assessment was performed by recording adverse events (AEs during and immediately after infusion, 30 minutes afterwards, and via follow-up at 7 days and 8 weeks. For efficacy assessment, hematological parameters were assessed prior to FCM infusion (pre-FCM and after 8 weeks. Economic impact of FCM given immediately after IFX was assessed.All 45 patients (35 Crohn´s disease, 10 ulcerative colitis received IFX 5mg/kg. 21 patients received 500mg FCM and 24 received 1000mg. FCM administration immediately after IFX corrected iron deficiency or IRA as shown by increases in hematological parameters. No AEs were reported during the safety evaluation at the end of FCM or IFX administration, 30 minutes, 7 days and 8 weeks afterwards, in either control or single-session groups. Total cost per patient for single-session administration was 354.63€; for patients receiving IFX and FCM on separate days, it was 531.94€, giving a 177.31€ per-patient cost saving.Single-session administration of FCM after IFX was safe and effective in IBD patients and can offer a good cost-benefit ratio and improve treatment adherence. To our knowledge, this study is the first to evaluate FCM and IFX administration in a single treatment session.

    Previous research has demonstrated that aerobic exercise has disparate effects on speed of processing and movement execution. In simple and choice reaction tasks, aerobic exercise appears to increase speed of movement execution while speed of processing is unaffected. In the flanker task, aerobic exercise has been shown to reduce response time on incongruent trials more than congruent trials, purportedly reflecting a selective influence on speed of processing related to cognitive control. However, it is unclear how changes in speed of processing and movement execution contribute to these exercise-induced changes in response time during the flanker task. This study examined how a single session of aerobic exercise influences speed of processing and movement execution during a flanker task using electromyography to partition response time into reaction time and movement time, respectively. Movement time decreased during aerobic exercise regardless of flanker congruence but returned to pre-exercise levels immediately after exercise. Reaction time during incongruent flanker trials decreased over time in both an aerobic exercise and non-exercise control condition indicating it was not specifically influenced by exercise. This disparate influence of aerobic exercise on movement time and reaction time indicates the importance of partitioning response time when examining the influence of aerobic exercise on speed of processing. The decrease in reaction time over time independent of aerobic exercise indicates that interpreting pre-to-post exercise changes in behavior requires caution. Copyright © 2017 IBRO.

    Full Text Available Transcranial direct current stimulation (tDCS has reportedly shown promising therapeutic effects for tinnitus (Forogh et al., 2016; Joos et al., 2014 [1,2]. Studies are ongoing to determine optimum treatment protocol and the site of stimulation. Findings of the early studies are heterogeneous and most studies have focused on single session tDCS and short follow-up periods. There is no study on repeated sessions of tDCS with long term follow-up. This study presents the results of a randomized clinical trial investigating the therapeutic effects of acute multi-session tDCS over dorsolateral prefrontal cortex (DLPFC on tinnitus symptoms and comorbid depression and anxiety in patients with chronic intractable tinnitus. The dataset includes the demographic information, audiometric assessments, tinnitus specific characteristics, and the response variables of the study. The response variables included the scores of tinnitus handicap inventory (THI, tinnitus loudness and tinnitus related distress based on 0–10 numerical visual analogue scale (VAS scores, beck depression inventory (BDI-II and beck anxiety inventory (BAI scores. The dataset included the scores of THI pre and immediately post intervention, and at one month follow-up; the tinnitus loudness and distress scores prior to intervention, and immediately, one hour, one week, and at one month after the last stimulation session. In addition, the BDI-II, and BAI scores pre and post intervention are included. The data of the real (n=25 and sham tDCS (n=17 groups are reported. The main manuscript of this dataset is 'Acute repeated sessions of bifrontal transcranial direct current stimulation for treatment of intractable tinnitus: a randomized controlled trial' (Bayat et al., submitted for publication [3].

    A single session of aerobic exercise is linked to faster motor responses; however, the effect on rate of short-term learning is less clear. The objective was to evaluate the influence of a single bout of aerobic exercise on the rate of short-term acquisition of a shape-letter association task requiring a motor response. 23 [11 females, age 20.8±2.7years] healthy young adults were evaluated using a randomly assigned crossover design which was counterbalanced for order before and after moderate (exercise) and light (control) intensity cycle ergometry. Participants performed 3 blocks, with each block consisting of one round of training and testing. During training, participants were tasked with learning 6 unique shape-letter associations. Subsequent testing required a key press response to a visually presented shape pattern. Response time and error rates were used to assess acquisition over the 3 blocks of testing. Mean response time was faster post-exercise relative to the other testing periods, and approached statistical significance compared to post-control (pexercise and control conditions). Error rate reduction (test block 1 minus test block 3) revealed that individuals had the smallest change in error rate post-exercise (pexercise which approached statistical significance (p=0.06) suggesting near-perfect error rates were obtained after only 2 testing blocks post-exercise compared to 3 blocks in the other testing periods. Support for augmentation of short-term learning was mixed as errors were reduced post-exercise while response time was not different between evaluations. Future work should include neurophysiological evaluation and a retention test to better elucidate the influence of aerobic exercise on rate of short-term learning.

    Recent research demonstrated that the symmetry of corticomotor drive with the paretic and nonparetic plantarflexor muscles was related to the biomechanical ankle moment strategy that people with chronic stroke used to achieve their greatest walking speeds. Rehabilitation strategies that promote corticomotor balance might improve poststroke walking mechanics and enhance functional ambulation. The study objectives were to test the effectiveness of a single session of gait training using functional electrical stimulation (FES) to improve plantarflexor corticomotor symmetry and plantarflexion ankle moment symmetry and to determine whether changes in corticomotor symmetry were related to changes in ankle moment symmetry within the session. This was a repeated-measures crossover study. On separate days, 20 people with chronic stroke completed a session of treadmill walking either with or without the use of FES of their ankle dorsi- and plantarflexor muscles. We calculated plantarflexor corticomotor symmetry using transcranial magnetic stimulation and plantarflexion ankle moment symmetry during walking between the paretic and the nonparetic limbs before and after each session. We compared changes and tested relationships between corticomotor symmetry and ankle moment symmetry following each session. Following the session with FES, there was an increase in plantarflexor corticomotor symmetry that was related to the observed increase in ankle moment symmetry. In contrast, following the session without FES, there were no changes in corticomotor symmetry or ankle moment symmetry. No stratification was made on the basis of lesion size, location, or clinical severity. These findings demonstrate, for the first time (to our knowledge), the ability of a single session of gait training with FES to induce positive corticomotor plasticity in people in the chronic stage of stroke recovery. They also provide insight into the neurophysiologic mechanisms underlying improvements in

    The concept of single-sex education for science and mathematics has recently received renewed discussion in both the popular and professional literature. So important is the topic within higher education that the Duke Journal of Gender Law and Policy sponsored a symposium called "Gender & The Higher Education Classroom: Maximizing the Learning Environment" in February 1996 (http://www.duke.edu/ jrd4/djgcnf96.htm). The concept is especially controversial in publicly supported educational institutions. The idea of offering an optional discussion session limited to a single sex in a university-level introductory astronomy course at a State-supported school was considered through discussions with a number of faculty and administrators, and through a questionnaire aimed at determining student attitudes toward the concept. The results of the student questionnaire will be presented. (While the questionnaire results will be seen to be in favor of such an optional discussion session, such sessions have not been offered.)

    This study investigated whether an acute session of high-intensity interval training (HIIT) is sufficient to alter lymphocyte function and redox status. Sixteen young healthy men underwent a HIIT session on a cycloergometer, consisting of eight bouts of 1 min at 90-100% of peak power, with 75 seconds of active recovery at 30 W between bouts. Venous blood was collected before, immediately after, and 30 minutes after the HIIT session. In response to Staphylococcus aureus superantigen B (SEB) stimulation, lymphocyte proliferation decreased and the IL-2 concentration increased after the HIIT session. However, the HIIT session had no effect on lymphocyte proliferation or IL-2 response to phytohemagglutinin stimulation. The HIIT session also induced lymphocyte redox imbalance, characterized by an increase in the concentration of thiobarbituric acid reactive substances and a decrease in the activity of the antioxidant enzyme catalase. Lymphocyte viability was not affected by the HIIT session. The frequencies of CD25+ and CD69+ T helper and B lymphocytes in response to superantigen stimulation were lower after exercise, suggesting that superantigen-induced lymphocyte activation was reduced by HIIT. However, HIIT also led to a reduction in the frequency of CD4+ and CD19+ cells, so the frequencies of CD25+ and CD69+ cells within the CD4 and CD19 cell populations were not affected by HIIT. These data indicate that the reduced lymphocyte proliferation observed after HIIT is not due to reduced early lymphocyte activation by superantigen. Our findings show that an acute HIIT session promotes lymphocyte redox imbalance and reduces lymphocyte proliferation in response to superantigenic, but not to mitogenic stimulation. This observation cannot be explained by alteration of the early lymphocyte activation response to superantigen. The manner in which lymphocyte function modulation by an acute HIIT session can affect individual immunity and susceptibility to infection is important

    Patients with cavernous sinus dural arteriovenous fistulas (CS dAVFs) with cortical venous varix are indicated for aggressive treatment because of the associated risk for intracranial hemorrhage. We present a case of surgical transvenous embolization in an 84-year-old woman with CS dAVF who presented with massive intracerebral hematoma. Cerebral angiograms revealed the dural AVF drained only into the superficial middle cerebral vein. Because an emergent mass reduction and prevention of rebleeding were necessary, single-session hematoma removal and transcranial embolization of a CS dAVF were performed in the neurosurgical operating room, using a mobile C-arm fluoroscopy. After the right frontotemporal craniotomy, intracerebral hematoma was removed and coil packing of the affected cavernous sinus was successfully performed via the dilated superficial middle cerebral vein. The transcortical vein approach enables occlusion of CS dAVF with isolated cortical venous drainage and may be a valuable alternative approach for some cases needed emergency craniotomy.

    Negative neurocognitive bias is a core feature of major depressive disorder that is reversed by pharmacological and psychological treatments. This double-blind functional magnetic resonance imaging study investigated for the first time whether electroconvulsive therapy modulates negative neurocognitive bias in major depressive disorder. Patients with major depressive disorder were randomised to one active ( n=15) or sham electroconvulsive therapy ( n=12). The following day they underwent whole-brain functional magnetic resonance imaging at 3T while viewing emotional faces and performed facial expression recognition and dot-probe tasks. A single electroconvulsive therapy session had no effect on amygdala response to emotional faces. Whole-brain analysis revealed no effects of electroconvulsive therapy versus sham therapy after family-wise error correction at the cluster level, using a cluster-forming threshold of Z>3.1 ( p2.3; pelectroconvulsive therapy-induced changes in parahippocampal and superior frontal responses to fearful versus happy faces as well as in fear-specific functional connectivity between amygdala and occipito-temporal regions. Across all patients, greater fear-specific amygdala - occipital coupling correlated with lower fear vigilance. Despite no statistically significant shift in neural response to faces after a single electroconvulsive therapy session, the observed trend changes after a single electroconvulsive therapy session point to an early shift in emotional processing that may contribute to antidepressant effects of electroconvulsive therapy.

    The early phase of psychotherapy has been regarded as a sensitive period in the unfolding of psychotherapy leading to positive outcomes. However, there is disagreement about the degree to which early (especially relationship-related) session experiences predict outcome over and above initial levels of distress and early response to treatment. The goal of the present study was to simultaneously examine outcome at post treatment as a function of (a) intake symptom and interpersonal distress as well as early change in well-being and symptoms, (b) the patient's early session-experiences, (c) the therapist's early session-experiences/interventions, and (d) their interactions. The data of 430 psychotherapy completers treated by 151 therapists were analyzed using hierarchical linear models. Results indicate that early positive intra- and interpersonal session experiences as reported by patients and therapists after the sessions explained 58% of variance of a composite outcome measure, taking intake distress and early response into account. All predictors (other than problem-activating therapists' interventions) contributed to later treatment outcomes if entered as single predictors. However, the multi-predictor analyses indicated that interpersonal distress at intake as well as the early interpersonal session experiences by patients and therapists remained robust predictors of outcome. The findings underscore that early in therapy therapists (and their supervisors) need to understand and monitor multiple interconnected components simultaneously.

    ATX-101 (deoxycholic acid injection) is the only injectable drug approved for submental fat (SMF) reduction. In the phase 3 REFINE trials, adults with moderate or severe SMF who were dissatisfied with the appearance of their face/chin were eligible to receive up to 6 treatment sessions with ATX-101 (2 mg/cm2) or placebo. Primary and secondary endpoints, evaluated at 12 weeks after last treatment, significantly favored ATX-101 supporting its efficacy for reducing SMF and the psychological impact of SMF, and increasing satisfaction with the appearance of the face/chin. To evaluate the efficacy and safety of ATX-101 by treatment session. This post-hoc analysis used pooled data from the REFINE trials to evaluate efficacy endpoints and adverse events following each treatment session to further characterize the ATX-101 treatment response and safety profile. In both treatment groups, mean injection volume declined over subsequent treatment sessions, though more markedly in the ATX-101 group. The majority of ATX-101-treated subjects achieved a ≥1-grade improvement in SMF within 2 to 4 treatment sessions based on either clinician or subject assessment. Furthermore, 19.1% of ATX-101-treated subjects (vs 3.9% of placebo-treated subjects) received fewer than 6 treatment sessions owing to subject satisfaction with treatment or lack of sufficient SMF for further treatment. In both treatment groups, the incidence/severity of common injection-site adverse events declined over subsequent treatment sessions. Although up to 6 treatment sessions were permitted in the REFINE trials, most ATX-101-treated subjects achieved an improvement in SMF within 2 to 4 treatment sessions.

    The goal of the present study was to explore how anger reduction via a single session of meditation might be measured using psychophysiological methodologies. To achieve this, 15 novice meditators (Experiment 1) and 12 practiced meditators (Experiment 2) completed autobiographical anger inductions prior to, and following, meditation training while respiration rate, heart rate, and blood pressure were measured. Participants also reported subjective anger via a visual analog scale. At both stages, the experienced meditators' physiological reaction to the anger induction reflected that of relaxation: slowed breathing and heart rate and decreased blood pressure. Naïve meditators exhibited physiological reactions that were consistent with anger during the pre-meditation stage, while after meditation training and a second anger induction they elicited physiological evidence of relaxation. The current results examining meditation training show that the naïve group's physiological measures mimicked those of the experienced group following a single session of meditation training.

    GPS TEC ionosphere maps were first applied to a series of K and Q band VLBA astrometry sessions to try to eliminate a declination bias in estimated source positions. Their usage has been expanded to calibrate X-band only VLBI observations as well. At K-band, approx.60% of the declination bias appears to be removed with the application of GPS ionosphere calibrations. At X-band however, it appears that up to 90% or more of the declination bias is removed, with a corresponding increase in RA and declination uncertainties of approx.0.5 mas. GPS ionosphere calibrations may be very useful for improving the estimated positions of the X-only and S-only sources in the VCS and RDV sessions.

    Therapeutic rapport between counselors and clients in drug user treatment has been shown to be an important predictor of follow-up outcomes. This naturalistic study investigated the relationship of counseling rapport to drug-related topics discussed in counseling sessions in a sample of 330 clients and nine counselors. These voluntary clients had been admitted to a private, for-profit outpatient methadone treatment in Texas between September 1995 and August 1997 and received no-fee services for a year for participation in this study. The data were gathered using forms in the TCU community treatment assessments (www.ibr.tcu.edu) that measured intake information, counseling session topics, and counselor evaluation of the client. A majority were males, Hispanic, had a pending legal status and the average age was 39. Co-occurring drug dependence for these heroin users included cocaine (38%) and alcohol (31%). The results supported the hypothesis that higher rapport would be associated with addressing clients in a more "supportive approach" that emphasized relapse prevention and strengths-building while lower rapport would be associated with a punitive counseling style that stressed program rules and compliance. The influences of client background, counselor differences, and during-treatment positive urines were also examined. Although counselors differed in their general manner of dealing with clients, each also showed flexibility determined in part by client behavior (such as continued cocaine use). The findings indicate that focusing on constructive solutions is the preferred counseling approach.

    In patients with pharmacoresistant focal epilepsy, resection of the epileptic focus can lead to freedom from seizures or significant improvement in well-selected candidates. Localization of the epileptic focus with multimodal concordance is crucial for a good postoperative outcome. Beyond the detection of epileptogenic lesions on structural MRI and focal hypometabolism on FDG PET, EEG-based Electric Source Imaging (ESI) and simultaneous EEG and functional MRI (EEG-fMRI) are increasingly applied for mapping epileptic activity. We here report presurgical multimodal interictal imaging using a hybrid PET/MR scanner for single-session FDG PET, MRI, EEG-fMRI and ESI. This quadrimodal imaging procedure was performed in a single session in 12 patients using a high-density (256 electrodes) MR-compatible EEG system and a hybrid PET/MR scanner. EEG was used to exclude subclinical seizures during uptake of the PET tracer, to compute ESI on interictal epileptiform discharges and to guide fMRI analysis for mapping haemodynamic changes correlated with interictal epileptiform activity. The whole multimodal recording was performed in less than 2 hours with good patient comfort and data quality. Clinically contributory examinations with at least two modalities were obtained in nine patients and with all modalities in five patients. This single-session quadrimodal imaging procedure provided reliable and contributory interictal clinical data. This procedure avoids multiple scanning sessions and is associated with less radiation exposure than PET-CT. Moreover, it guarantees the same medication level and medical condition for all modalities. The procedure improves workflow and could reduce the duration and cost of presurgical epilepsy evaluations.

    Full Text Available Mandana Modirrousta,1,2 Benjamin P Meek,2 Sara L Wikstrom2 1Department of Psychiatry, University of Manitoba, 2Mental Health, Saint Boniface General Hospital, Winnipeg, MB, Canada Purpose: There is no clinical consensus on the optimal protocol for the treatment of major depressive disorder (MDD using repetitive transcranial magnetic stimulation (rTMS. Accelerated protocols using more than a single session of treatment per day have been suggested as a means to reduce the overall length of time required for rTMS therapy. The objective of this study is to compare the treatment outcomes of patients with MDD who received two sessions of rTMS per day vs those who received one session per day, keeping the overall number of delivered pulses constant.Patients and methods: In a retrospective study, we compared treatment outcomes of 36 patients with MDD who received 30 sessions of high-frequency (10 Hz rTMS over the left dorsolateral prefrontal cortex. Patients received 3,000 pulses per session (5 s trains, 25 s intertrain interval at 110% of resting motor threshold using a figure-eight coil. Patients received either two rTMS sessions per day (n=17 or one session per day (n=19. Depression symptoms were assessed by a psychiatrist using the Hamilton Rating Scale for Depression at baseline and after every 10 sessions of rTMS.Results: The majority of patients in both groups responded to treatment, and there was a trend toward greater response rate in the twice-daily (TD group (82.4% compared to the once-daily (OD group (52.6%. TD stimulation was tolerable for patients and produced no adverse side effects. Patients in the TD group experienced an improvement in symptoms faster than the OD group due to the accelerated therapy period.Conclusion: Administration of two rTMS treatment sessions per day is tolerable for patients and does not seem to be inferior in efficacy to a OD protocol. TD administration has the benefit of producing symptom improvement over a

  12. AN OVERVIEW OF TRAINING METHODS THAT PROMOTE THE HIGHEST LIPID OXIDATION DURING AND AFTER A SINGLE EXERCISE SESSION

    Full Text Available Given that physical activity is the most effective way to increase lipid oxidation, its effects are influenced by several factors. The goal of this review was to identify the most effective methods that facilitate the highest lipid oxidation during and after a single exercise session. For this purpose, the available scientific literature was examined using PubMed, Web of Science, Google Scholar and Cochrane Library databases up to June 2013 with the following keywords: excess post exercise oxygen consumption, exercise fatty acid, energy expenditure exercise and interval training. From the identified 48,583 potentially relevant references, 172 of them met all the required criteria. It was found out that prolonged (> 30 min moderate intensity (55 − 70 % VO2max exercise such as walking, jogging or cycling is the most effective way to increase lipid oxidation during and after a single exercise session. Low-volume high-intensity interval exercise is supposed to be as effective as traditional exercise with continuous endurance, with the main effect on lipid oxidation after the session and similar long-term metabolic adaptations. However, more research is still needed to compare the effects of regular resistance exercise with traditional endurance and high-intensity interval exercise. Finally, nutrition is also a significant factor since food rich in fat and low in carbohydrates promotes greater lipid oxidation.

    The purpose of this study was to assess the effectiveness of a single session of global postural reeducation (GPR) in postural sway in young adult university students who use data visualization screens. A randomized controlled trial with 2 parallel groups was performed. Sixty-four subjects were randomized in the experimental group (12 men and 20 women) who underwent the GPR session, and a control group (13 men and 19 women) that did not receive any intervention was included. Center of pressure (COP) was assessed using a stabilometric platform, with eyes open and eyes closed before, immediately after, 48 hours after, and 7 days after intervention in both groups. In the interaction of time and gender, statistically significant differences were found for the area covered by COP (P = .020) and for the standard deviation (SD) in the mediolateral axis (P = .035). Considering the complete interaction time, gender, and group, statistically significant differences were found (P = .015) for the anteroposterior rate covered by COP and the SD in the anteroposterior axis (P = .033). In eyes closed condition, the intersubject analysis showed statistically significant differences for the interaction between group and gender for the variable mediolateral SD (P = .043). Considering the interaction of time with group, statistically significant differences were found for full length covered by COP (P = .017). Changes in postural sway were observed after a single GPR session, mainly at 48 hours, with different behaviors between men and women. Copyright © 2017. Published by Elsevier Inc.

    Intermittent pneumatic leg compressions (IPC) have proven to be an effective noninvasive approach for treatment of patients with claudication, but the mechanisms underlying the clinical benefits remain elusive. In the present study, a rodent model of claudication produced by bilateral ligation of the femoral artery was used to investigate the acute impact of a single session of IPC (150 min) on hemodynamics, skeletal muscle (tibialis anterior), and isolated collateral artery (perforating artery) expression of a subset of genes associated with inflammation and vascular remodeling. In addition, the effect of compression frequency (15 vs. 3 compressions/min) on the expression of these factors was studied. In ligated animals, IPC evoked an increase of monocyte chemoattractant protein-1 (MCP-1) and cytokine-induced neutrophil chemoattractant 1 (CXCL1) mRNA (P < 0.01) and immunostaining (P < 0.05), as well as a minor increase in VEGF immunostaining in the muscle endomysium 150 min postintervention. Further, collateral arteries from these animals showed an increased expression of MCP-1 (approximately twofold, P = 0.02). These effects were most evident in the group exposed to the high-frequency protocol (15 compressions/min). In contrast, IPC in sham-operated control animals evoked a modest initial upregulation of VEGF (P = 0.01), MCP-1 (P = 0.02), and CXCL1 (P = 0.03) mRNA in the muscle without concomitant changes in protein levels. No changes in gene expression were observed in arteries isolated from sham animals. In conclusion, IPC acutely up-regulates the expression of important factors involved in vascular remodeling in the compressed muscle and collateral arteries in a model of hindlimb ischemia. These effects appear to be dependent on the compression frequency, such that a high compression frequency (15 compressions/min) evokes more consistent and robust effects compared with the frequency commonly employed clinically to treat patients with claudication (3

    Single-session interventions (SSIs) show promise in the prevention and treatment of youth psychopathology, carrying potential to improve the scalability and accessibility of youth psychological services. However, existing SSIs have conferred greater benefits for youths with anxiety, compared to depression or comorbid problems, and their effects have generally waned over time - particularly for follow-ups exceeding 3 months. To help address these discrepancies, we tested whether a novel SSI teaching growth mindset of personality (the belief that personality is malleable) could reduce depression and anxiety and strengthen perceived control in high-risk adolescents (N = 96, ages 12-15). At baseline, youths were randomized to receive a 30-min, computer-guided growth mindset intervention or a supportive-therapy control. Youths and parents reported youth anxiety and depressive symptoms, and youths reported their levels of perceived control, at baseline and across a 9-month follow-up period. Compared to the control program, the mindset intervention led to significantly greater improvements in parent-reported youth depression (d = .60) and anxiety (d = .28), youth-reported youth depression (d = .32), and youth-reported perceived behavioral control (d = .29) by 9-month follow-up. Intervention effects were nonsignificant for youth-reported anxiety, although 9-month effect sizes reached the small-to-medium range (d = .33). Intervention group youths also experienced more rapid improvements in parent-reported depression, youth-reported depression, and perceived behavioral control across the follow-up period, compared to control group youths. Findings suggest a promising, scalable SSI for reducing internalizing distress in high-risk adolescents. NCT03132298. © 2017 Association for Child and Adolescent Mental Health.

Lastly, the three tDCS sessions had comparable effects on the wanting/liking of food and on bulimic behaviours during the 24 hours post-stimulation.These data suggest that single-session tDCS transiently improves symptoms of BN. They also help to elucidate possible mechanisms of action and highlight the importance of selecting the optimal electrode montage. Multi-session trials are needed to determine whether tDCS has potential for development as a treatment for adult BN.

    Full Text Available Oral health promotion through schools is recommended by the World Health Organization (WHO for improving knowledge, attitude, and behavior related to oral health and for prevention and control of dental diseases among school children. In low resource settings, it is important to develop evidence for health education methods in oral health behavioral practices. The objectives of this study were to assess both the baseline awareness and practices regarding oral hygiene and the impact of a single education session on the change in oral health behavior. A school based, cross-sectional study on 112 primary school children was conducted after obtaining the consent of the school authorities and parents. A pretested, structured proforma was used for baseline awareness and behavior regarding oral health. A 30 min educational session was imparted and after 1 month, and the oral health practices were reassessed to find out the impact of the education session. Baseline survey revealed the following findings. Self-reported dental problems were found in 48.22% of the children in the last 6 months. When asked about the risk factors for dental problems, 28.57% mentioned eating sweets followed by improper brushing, whereas 40.17% were not aware about any risk factor for dental problems. It was found that 28.57% of the children did not brush their teeth regularly, whereas 35.71% used a tooth-brush for brushing their teeth. After the intervention, it was observed that there was a significant improvement in the proportion of children using a toothbrush for cleaning their teeth and of those who rinsed their mouth after meals. In conclusion, even a single education session was found to be effective in bringing about a change in the oral health behavior of primary school children.

    This study aimed to evaluate the implications of the number of samples per panelist in experimental precision and relative efficiency of treatment comparisons when modelling order effects for Dulce de Leche samples using a Sudoku design. Precision is defined as small variance and relative efficiency is defined as smaller variance than other alternative. Both are related to increasing discrimination power. A series of 8 Sudoku 16×16 squares being 4 randomized independently and 4 others in the reverse order, was designed to allow a linear model fitting to experiments of different sizes (orders 1 to 4, 1 to 8, 1 to 12 and 1 to 16). Data from 112 panelists were kept. Responses were recorded using a nine-point hedonic scale. Data was analyzed using a mixed linear model panelist, order and treatment (sample) effects. Analysis has shown a pronounced order effect, showing a first sample effect overestimation. Moreover, it was noted that order effect was rather evidenced in the first four orders, making for a relatively more precise experiment than the ones using remaining samples. Therefore, the use of Sudoku can be a convenient strategy to organize smaller testing sessions that could result in efficient experiments, with small variance of the estimated averages or effects and needing a lot less panelists to make a design as efficient as the large one used. Moreover, Sudoku can also inspire an efficient design that allows different test sessions. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Exergames appear to be a promising tool to increase energy expenditure and physical fitness. However, less is known about the effect of a single session of an exergame on anxiety state. Thus, the aim of this study was to evaluate the effects of a single session of the exergame Zumba ® Fitness (Xbox 360 Kinect ® ) on the anxiety state of healthy young women. Forty healthy young women (22.9 ± 3.7 years; 62.43 ± 8.75 kg; 1.64 ± 0.06 m; 23.05 ± 2.75 kg/m 2 ; [Formula: see text]O 2 max of 41.23 ± 10.61 mL/kg/min) performed ∼20 minutes of the exergame Zumba Fitness using the Xbox 360 Kinect. The state anxiety (State Anxiety Inventory) and level of enjoyment (Physical Activity Enjoyment Scale) were evaluated before and after intervention. Rating perceived exertion (Borg scale) and heart rate (HR) were also tracked and collected. A single exergame session significantly reduced the state anxiety of the participants (P = 0.0230, effect size = 0.62, CI 0.34-0.90). However, no statistically significant correlation was found between enjoyment and absolute (r = -0.10, P = 0.5345) or relative change in state anxiety (r = -0.17, P = 0.2869). A moderate positive correlation was found between enjoyment and performance in the exergame Zumba Fitness (r = 0.59, P = 0.0001). The mean HR during exergames was 137 ± 19 bpm (∼70% of predicted HRmax). The exergame Zumba Fitness seems to be a useful tool to reduce state anxiety in a nonclinical sample of healthy women.

    Full Text Available Abstract Objective Malignant tumors that involve the skull base pose significant challenges to the clinician because of the proximity of critical neurovascular structures and limited effectiveness of surgical resection without major morbidity. The purpose of this study was to evaluate the efficacy and safety of multi-session radiosurgery in patients with malignancies of the skull base. Methods Clinical and radiographic data for 37 patients treated with image-guided, multi-session radiosurgery between January 2002 and December 2007 were reviewed retrospectively. Lesions were classified according to involvement with the bones of the base of the skull and proximity to the cranial nerves. Results Our cohort consisted of 37 patients. Six patients with follow-up periods less than four weeks were eliminated from statistical consideration, thus leaving the data from 31 patients to be analyzed. The median follow-up was 37 weeks. Ten patients (32% were alive at the end of the follow-up period. At last follow-up, or the time of death from systemic disease, tumor regression or stable local disease was observed in 23 lesions, representing an overall tumor control rate of 74%. For the remainder of lesions, the median time to progression was 24 weeks. The median progression-free survival was 230 weeks. The median overall survival was 39 weeks. In the absence of tumor progression, there were no cranial nerve, brainstem or vascular complications referable specifically to CyberKnife® radiosurgery. Conclusion Our experience suggests that multi-session radiosurgery for the treatment of malignant skull base tumors is comparable to other radiosurgical techniques in progression-free survival, local tumor control, and adverse effects.

    This study examined the efficacy of combining two promising approaches to treating children's specific phobias, namely attention training and one 3-h session of exposure therapy ('one-session treatment', OST). Attention training towards positive stimuli (ATP) and OST (ATP+OST) was expected to have more positive effects on implicit and explicit cognitive mechanisms and clinical outcome measures than an attention training control (ATC) condition plus OST (ATC+OST). Thirty-seven children (6-17 years) with a specific phobia were randomly assigned to ATP+OST or ATC+OST. In ATP+OST, children completed 160 trials of attention training responding to a probe that always followed the happy face in happy-angry face pairs. In ATC+OST, the probe appeared equally often after angry and happy faces. In the same session, children completed OST targeting their phobic situation/object. Clinical outcomes included clinician, parent and child report measures. Cognitive outcomes were assessed in terms of change in attention bias to happy and angry faces and in danger and coping expectancies. Assessments were completed before and after treatment and three-months later. Compared to ATC+OST, the ATP+OST condition produced (a) significantly greater reductions in children's danger expectancies about their feared situations/object during the OST and at three-month follow-up, and (b) significantly improved attention bias towards positive stimuli at post-treatment, which in turn, predicted a lower level of clinician-rated phobia diagnostic severity three-months after treatment. There were no significant differences between ATP+OST and ATC+OST conditions in clinician, parent, or child-rated clinical outcomes. Training children with phobias to focus on positive stimuli is effective in increasing attention towards positive stimuli and reducing danger expectancy biases. Studies with larger sample sizes and a stronger 'dose' of ATP prior to the OST may reveal promising outcomes on clinical measures

    Abstract Background Negative neurocognitive bias is a core feature of depression that is reversed by antidepressant drug treatment. However, it is unclear whether modulation of neurocognitive bias is a common mechanism of distinct biological treatments. This randomized controlled functional magnetic resonance imaging study explored the effects of a single electroconvulsive therapy session on self-referent emotional processing. Methods Twenty-nine patients with treatment-resistant major depressive disorder were randomized to one active or sham electroconvulsive therapy session at the beginning of their electroconvulsive therapy course in a double-blind, between-groups design. The following day, patients were given a self-referential emotional word categorization test and a free recall test. This was followed by an incidental word recognition task during whole-brain functional magnetic resonance imaging at 3T. Mood was assessed at baseline, on the functional magnetic resonance imaging day, and after 6 electroconvulsive therapy sessions. Data were complete and analyzed for 25 patients (electroconvulsive therapy: n = 14, sham: n = 11). The functional magnetic resonance imaging data were analyzed using the FMRIB Software Library randomize algorithm, and the Threshold-Free Cluster Enhancement method was used to identify significant clusters (corrected at P words. However, electroconvulsive therapy reduced the retrieval-specific neural response for positive words in the left frontopolar cortex. This effect occurred in the absence of differences between groups in behavioral performance or mood symptoms. Conclusions The observed effect of electroconvulsive therapy on prefrontal response may reflect early facilitation of memory for positive self-referent information, which could contribute to improvements in depressive symptoms including feelings of self-worth with repeated treatments.

    Treatment in bulimia nervosa is challenging, with rates of successful treatments for only about 50% of all patients. This study aimed to identify predictors of outcome through secondary analysis of data from a randomized clinical trial that compared inpatient and day hospital treatment for bulimia. Process measures included assessments of patients' in-session experiences, therapeutic alliance, and therapy-related intersession experiences (ISE). ISE measures were better predictors of outcome than pretreatment variables (e.g., social adjustment) or global therapeutic alliance. Outcome at 3 month follow-up was strongly related to the ISE dimension Recreating Therapeutic Dialogue with Negative Emotions, indicating a heightened risk of failure. Prediction of outcome by these variables showed a sensitivity of 0.86 and a specificity of 0.78, and 83% of patients could be correctly classified. These results show that certain aspects of ISE may serve as early and reliable indicators of long term treatment failure, prompting alternate treatment approaches and opening new directions of research.

    Accredited medical schools are required to prepare students to recognize the social determinants of health, such as privilege, yet privilege education has been overlooked in medical school curricula. The purpose of this study is to determine whether a single class session on privilege, within a social justice elective offered to first and second year medical students, is sufficient to change the perspective of medical students concerning their own personal privilege. A pre-class survey, followed by a class session on privilege, and post-class survey were conducted. Thirteen of the 18 students enrolled in the elective completed the pre-class survey. Ten students completed the post-class survey, although only 9 completed both the pre- and post-class surveys. The demographic profile of the participants was 93% Asian and 7% White ethnicity, with 57% identifying as being culturally American. There was no significant difference between average male and female or between age groups' self-assessed privilege amounts. For all characteristics tested, except hair color, participants had an increased self-assessed privilege perspective following the class. Three participants had an overall positive difference in privilege perspective, three participants had an overall negative difference in privilege perspective, and three participants had only a minimal change in privilege perspective. The absolute total difference in privilege perspective was 25 units of change. The single class session on privilege was sufficient to change significantly the perspective of medical students on their own personal privilege; however, future studies with larger groups of medical students are needed to elucidate other findings suggested by this study.

    We investigated the skeletal muscle adaptation to l-arginine supplementation prior to a single session of resistance exercise (RE) during the early phase of muscle repair. Wistar rats were randomly assigned into non-exercised (Control), RE plus vehicle (RE); RE plus l-arginine (RE+L-arg) and RE plus aminoguanidine (RE+AG) groups. Animals received four doses of either vehicle (0.9% NaCl), l-arg (1 g/b.w.), or AG (iNOS inhibitor) (50 mg/b.w.). The animals performed a single RE session until the concentric failure (ladder climbing; 80% overload) and the skeletal muscles were harvested at 0, 8, 24, and 48 hours post-RE. The RE resulted in increased neutrophil infiltrate (24 hours post-RE) (3621 vs 11852; Pl-arginine supplementation attenuates neutrophil infiltration (5622; Pl-arginine supplementation seems to attenuate the resolution of RE-induced muscle inflammation and up-regulates MyoD expression during the early phase of muscle repair. © 2017 John Wiley & Sons A/S.

    Although researchers have not yet examined the applicability of mindfulness for weight-gain prevention, mindfulness training has the potential to increase an individual's awareness of factors that enable an individual to avoid weight gain caused by overconsumption. The study intended to examine the effects of 1 h of mindfulness training on state mindfulness and food consumption. The research team performed a pilot study. The study occurred at an urban, northeastern, Catholic university. Participants were 26 undergraduate, English-speaking students who were at least 18 y old (77% female, 73% Caucasian). Students with food allergies, an inability to fast, or a current or past diagnosis of an eating disorder were ineligible. Participants fasted for 4 h. Between the third and fourth hours, they attended a 1-h session of mindfulness training that integrated three experiential mindfulness exercises with group discussion. Following training, they applied the skills they learned during a silent lunch. The Toronto Mindfulness Scale (TMS), the Awareness subscale of the Philadelphia Mindfulness Scale (PHLMS-AW), and a modified version of the Acting with Awareness subscale of the Five-Facet Mindfulness Questionnaire (FFMQ-AW) were used preand posttraining to assess changes in state mindfulness, present-moment awareness, and mealtime awareness, respectively. A postmeal, subjective hunger/fullness Likert scale was used to assess food consumption (healthy vs unhealthy consumption). The study found a statistically significant increase in state mindfulness (P=.002). Eighty-six percent of participants engaged in healthy food consumption. No statistically significant changes occurred in either present-moment awareness (P=.617) or mealtime awareness (P=.483). Preliminary results suggest promising benefits for use of mindfulness training on weight-gain prevention in healthy individuals. More research is needed to understand the impact that mindfulness may have on long-term, weight

    To evaluate one-session endodontic treatment with aPDT and two-session treatment with calcium hydroxide (CH)-based dressing in dog's teeth with apical periodontitis. After experimental induction of apical periodontitis, 48 teeth were randomly assigned to the following groups: groups OS/aPDT120d and OS/aPDT180d (one-session treatment with aPDT) and groups TS/CH120d and TS/CH180d (two-session treatment with CH-based dressing-control groups). The animals were euthanized after 120 and 180 days. After histotechnical processing, microscopic and radiographic analyses were performed. Data were analyzed by Kruskal-Wallis and Fisher's exact tests (α = 0.05). Groups TS/CHs presented repaired resorbed cemental areas, with collagen bundles and few inflammatory cells. In groups OS/aPDTs, the areas of cemental resorption were not repaired with reduced presence of cells and fibers. In the analysis of the apical closure, fluorescence microscopy and percentage of radiographic reduction of lesions, there was significant difference between groups TS/CH120d and OS/aPDT120d and between TS/CH180d and OS/aPDT180d (p session endodontic treatment using a CH-based dressing in teeth with apical periodontitis.

    The authors have used transurethral microwave thermotherapy in the treatment of benign prostatic hyperplasia since October 1991. Irreversible cell damage occurs when the microwaves heat the periurethral prostatic tissue. The urethra is simultaneously cooled and is not destroyed during treatment. The patients are not hospitalized. Transurethral microwave thermotherapy is performed under local anaesthesia, no other form of analgesia has been found necessary. Included were patients with symptomatic prostatic obstruction who would otherwise have received operative or pharmacologic treatment. Patients with high residual urine, large middle lobe, urethral stricture, prostatic cancer, decreased renal function, urinary infection or metal implants were excluded. It was observed a marked improvement in the Madsen symptom score after transurethral microwave thermotherapy. The score decreased from 12 before treatment to five after six weeks and 4.6 after six moths. Flow increased from 8.9 to 9.7 ml/s. There was a significant reduction in the residual urine from 102 ml preoperatively to 69 ml after six months. The volume of the prostate was only slightly reduced after transurethral microwave thermotherapy. Postoperative edema caused urinary retention in 13% of the patients. Two patients required transurethral resection of the prostata. 5 refs., 3 figs., 1 tab.

Patients and methods: Thirty independent adults aged >65 years took part in the randomized controlled trial. The study was conducted within an exercise science laboratory. Participants were randomly divided into three groups following baseline locomotor testing: motor imagery training, physical training, and control groups. The motor imagery training group completed 20 imagined repetitions of a locomotor task, the physical training group completed 20 physical repetitions of a locomotor task, and the control group spent 25 minutes playing mentally stimulating games on an iPad. Imagined and physical performance times were measured for each training repetition. Gait speed (preferred and fast, timed-up-and-go, gait variability and the time to complete an obstacle course were completed before and after the single training session. Results: Motor learning occurred in both the motor imagery training and physical training groups. Motor imagery training led to refinements in motor planning resulting in imagined movements better matching the physically performed movement at the end of training. Motor imagery and physical training also promoted improvements in some locomotion outcomes as demonstrated by medium to large effect size improvements after training for fast gait speed and timed-up-and-go. There were no training effects on gait variability. Conclusion: A single session

    Full Text Available Objective. High intensity interval treadmill training (HIITT has been gaining popularity for gait rehabilitation after stroke. In this study, we examined the changes in excitability of the lower limb motor cortical representation (M1 in chronic stroke survivors following a single session of HIITT. We also determined whether exercise-induced changes in excitability could be modulated by transcranial direct current stimulation (tDCS enhanced with a paretic ankle skill acquisition task. Methods. Eleven individuals with chronic stroke participated in two 40-minute treadmill-training sessions: HIITT alone and HITT preceded by anodal tDCS enhanced with a skill acquisition task (e-tDCS+HIITT. Transcranial magnetic stimulation (TMS was used to assess corticomotor excitability of paretic and nonparetic tibialis anterior (TA muscles. Results. HIIT alone reduced paretic TA M1 excitability in 7 of 11 participants by ≥ 10%. e-tDCS+HIITT increased paretic TA M1 excitability and decreased nonparetic TA M1 excitability. Conclusions. HIITT suppresses corticomotor excitability in some people with chronic stroke. When HIITT is preceded by tDCS in combination with a skill acquisition task, the asymmetry of between-hemisphere corticomotor excitability is reduced. Significance. This study provides preliminary data indicating that the cardiovascular benefits of HIITT may be achieved without suppressing motor excitability in some stroke survivors.

    Prior experiments indicated that reading literary fiction improves mentalising performance relative to reading popular fiction, non-fiction, or not reading. However, the experiments had relatively small sample sizes and hence low statistical power. To address this limitation, the present authors conducted four high-powered replication experiments (combined N = 1006) testing the causal impact of reading literary fiction on mentalising. Relative to the original research, the present experiments used the same literary texts in the reading manipulation; the same mentalising task; and the same kind of participant samples. Moreover, one experiment was pre-registered as a direct replication. In none of the experiments did reading literary fiction have any effect on mentalising relative to control conditions. The results replicate earlier findings that familiarity with fiction is positively correlated with mentalising. Taken together, the present findings call into question whether a single session of reading fiction leads to immediate improvements in mentalising.

    The "clarification session" has been implicated as an important component of the treatment of families affected by incest. On the basis of information presented in clinical literature, however, the specific nature of this intervention varies widely. This exploratory study examined the practices and attitudes regarding clarification sessions of select members of the Association for the Treatment of Sexual Abusers. Surveys were completed by 483 members. Results indicated that approximately 77% of respondents had experience in conducting clarification sessions. The top two reported reasons for conducting clarification sessions were for the perpetrator to assume all responsibility for the abuse and to decrease the level of self-blame of the victim. The majority of respondents concurred that several activities needed to occur prior to the clarification session, whereas less consensus was indicated for activities that were deemed essential during the clarification session. Respondents' practices, attitudes, and beliefs are discussed in terms of the current state of limited, empirically based knowledge in this area. Directions for future research are suggested.

    Background and purpose: Paralysis observed during a study of vertebral bone tolerance to single-session irradiation led to further study of the dose-related incidence of motor peripheral neuropathy. Materials and methods: During a bone tolerance study, cervical spinal nerves of 15 minipigs received bilateral irradiation to levels C5–C8 distributed into three dose groups with mean maximum spinal nerve doses of 16.9 ± 0.3 Gy (n = 5), 18.7 ± 0.5 Gy (n = 5), and 24.3 ± 0.8 Gy (n = 5). Changes developing in the gait of the group of pigs receiving a mean maximum dose of 24.3 Gy after 10–15 weeks led to the irradiation of two additional animals. They received mean maximum dose of 24.9 ± 0.2 Gy (n = 2), targeted to the left spinal nerves of C5–C8. The followup period was one year. Histologic sections from spinal cords and available spinal nerves were evaluated. MR imaging was performed on pigs in the 24.9 Gy group. Results: No pig that received a maximum spinal nerve point dose ⩽19.0 Gy experienced a change in gait while all pigs that received ⩾24.1 Gy experienced paralysis. Extensive degeneration and fibrosis were observed in irradiated spinal nerves of the 24.9 Gy animals. All spinal cord sections were normal. Irradiated spinal nerve regions showed increased thickness and hypointensity on MR imaging. Conclusion: The single-session tolerance dose of the cervical spinal nerves lies between 19.0 and 24.1 Gy for this model

    Full Text Available Musical performance is a skilled activity performed under intense pressure, thus is often a profound source of anxiety. In other contexts, anxiety and its concomitant symptoms of sympathetic nervous system arousal have been successfully ameliorated with HRV biofeedback (HRV BF, a technique involving slow breathing which augments autonomic and emotional regulatory capacity.This randomised-controlled study explored the impact of a single 30-minute session of HRV BF on anxiety in response to a highly stressful music performance.A total of 46 trained musicians participated in this study and were randomly allocated to a slow breathing with or without biofeedback or no-treatment control group. A 3 Group×2 Time mixed experimental design was employed to compare the effect of group before and after intervention on performance anxiety (STAI-S and frequency domain measures of HRV.Slow breathing groups (n=30 showed significantly greater improvements in high frequency (HF and LF/HF ratio measures of HRV relative to control (n=15 during 5 minute recordings of performance anticipation following the intervention (effect size: η(2 =0.122 and η(2 =0.116, respectively. The addition of biofeedback to a slow breathing protocol did not produce differential results. While intervention groups did not exhibit an overall reduction in self-reported anxiety, participants with high baseline anxiety who received the intervention (n=15 displayed greater reductions in self-reported state anxiety relative to those in the control condition (n=7 (r=0.379.These findings indicate that a single session of slow breathing, regardless of biofeedback, is sufficient for controlling physiological arousal in anticipation of psychosocial stress associated with music performance and that slow breathing is particularly helpful for musicians with high levels of anxiety. Future research is needed to further examine the effects of HRV BF as a low-cost, non-pharmacological treatment for

    To assess the changes on various physiological cardio-respiratory parameters with a single chest physiotherapy session in mechanically ventilated and extubated preterm neonates with respiratory distress syndrome. This is a prospective observational study in a neonatal intensive care unit setting. Sixty preterm neonates with respiratory distress syndrome, thirty mechanically ventilated and thirty extubated preterm neonates requiring chest physiotherapy were enrolled in the study. Parameters like heart rate (HR), respiratory rate (RR), Silverman Anderson score (SA score in extubated), oxygen saturation (SpO2) and auscultation findings were noted just before, immediately after chest physiotherapy but before suctioning, immediately after suctioning and after 5 minutes of the session. The mean age of neonates was 9.55±5.86 days and mean birth weight was 1550±511.5 g. As there was no significant difference in the change in parameters on intergroup comparison, further analysis was done considering two groups together (n = 60) except for SA score. As SA score was measured only in extubated neonates. HR did not change significantly during chest physiotherapy compared to the baseline but significantly decreased after 15 minutes (p = 0.01). RR and SA score significantly increased after suctioning (p = 0.014) but reduced after 15 minutes (p = physiotherapy (p = physiotherapy may help facilitate the overall well-being of a fragile preterm neonate. Lung auscultation finding suggests that after suctioning, there was a significant reduction in crepitation (p = 0.0000) but significant increase in crepitation after 15 minutes (p = physiotherapy. Chest physiotherapy is safe in preterm neonates. Suctioning causes significant cardio-respiratory parameter changes, but within normal physiological range. Thus, chest physiotherapy should be performed with continuous monitoring only when indicated and not as a routine procedure. More research is needed

    Research on the clinical applications of psychedelic-assisted psychotherapy has demonstrated promising early results for treatment of alcohol dependence. Detailed description of the content and methods of psychedelic-assisted psychotherapy, as it is conducted in clinical settings, is scarce. Methods: An open-label pilot (proof-of-concept) study of psilocybin-assisted treatment of alcohol dependence (NCT01534494) was conducted to generate data for a phase 2 RCT (NCT02061293) of a similar treatment in a larger population. The present paper presents a qualitative content analysis of the 17 debriefing sessions conducted in the pilot study, which occurred the day after corresponding psilocybin medication sessions. Results: Participants articulated a series of key phenomena related to change in drinking outcomes and acute subjective effects of psilocybin. Discussion: The data illuminate change processes in patients' own words during clinical sessions, shedding light on potential therapeutic mechanisms of change and how participants express effects of psilocybin. This study is unique in analyzing actual clinical sessions, as opposed to interviews of patients conducted separately from treatment.

    To evaluate the response of the apical and periapical tissues of dog teeth with apical periodontitis after one-session root canal treatment with and without antimicrobial photodynamic therapy (aPDT) compared with the use of an intracanal dressing. Sixty root canals with an induced periapical lesion were instrumented and assigned to three groups: I, two-session root canal treatment using antibacterial dressing with calcium hydroxide-based paste; II, one-session root canal treatment using aPDT; and III, one-session root canal treatment in which the root canals were filled immediately after biomechanical preparation. The animals were euthanized after a 90-day experimental period. The maxillas and mandibles with teeth were submitted to histotechnical processing and haematoxylin-eosin staining. Descriptive microscopic analysis of the apical and periapical region characteristics was performed, as well as morphometric assessment of the periapical lesion areas in fluorescence microscopy. Quantitative data were analysed statistically by the nonparametric Kruskal-Wallis test and Dunn's post-test (α = 0.05).

    To assess the safety of increasing the number of waves per session in the treatment of urolithiasis using extracorporeal lithotripsy. Prospective, comparative, nonrandomized parallel study of patients with renoureteral lithiasis and an indication for extracorporeal lithotripsy who were consecutively enrolled between 2009 and 2010. We compared group I (160 patients) treated on schedule with a standard number of waves/session (mean 2858,3±302,8) using a Dornier lithotripter U/15/50 against group II (172 patients) treated with an expanded number of waves/session (mean, 6728,9±889,6) using a Siemens Modularis lithotripter. The study variables were age, sex, location, stone size, number of waves/session and total number of waves to resolution, stone-free rate (SFR) and rate of complications (Clavien-Dindo classification). Student's t-test and the chi-squared test were employed for the statistical analysis. The total rate of complications was 11.9% and 10.46% for groups I and II, respectively (P=.39). All complications were minor (Clavien-Dindo grade I). The most common complications were colic pain and hematuria in groups I and II, respectively, with a similar treatment intolerance rate (P>.05). The total number of waves necessary was lower in group II than in group I (P=.001), with SFRs of 96.5% and 71.5%, respectively (P=.001). Treatment with an expanded number of waves per session in extracorporeal lithotripsy does not increase the rate of complications or their severity. However, it could increase the overall effectiveness of the treatment. Copyright © 2014 AEU. Publicado por Elsevier España, S.L.U. All rights reserved.

    One hundred and ninety-six youth, ages 7-16, who fulfilled Diagnostic and Statistical Manual of Mental Disorders (4th ed.) criteria for various specific phobias were randomized to a one-session exposure treatment, education support treatment, or a wait list control group. After the waiting period, the wait list participants were offered treatment and, if interested, rerandomized to 1 of the 2 active treatments. The phobias were assessed with semistructured diagnostic interviews, clinician severity ratings, and behavioral avoidance tests, whereas fears, general anxiety, depression, and behavior problems were assessed with self- and parent report measures. Assessments were completed pretreatment, posttreatment, and at 6 months following treatment. Results showed that both treatment conditions were superior to the wait list control condition and that 1-session exposure treatment was superior to education support treatment on clinician ratings of phobic severity, percentage of participants who were diagnosis free, child ratings of anxiety during the behavioral avoidance test, and treatment satisfaction as reported by the youth and their parents. There were no differences on self-report measures. Treatment effects were maintained at follow-up. Implications of these findings are discussed. Copyright 2009 APA

    Full Text Available ABSTRACT Background Ear Acupuncture (EA is a form of acupuncture in which needles are applied to the external ear and has been used in multiple painful conditions. Low back pain (LBP is highly prevalent in active individuals and causes high economic burden to health systems worldwide. LBP affects the person’s ability to keep balance, especially in challenging conditions. Objective The aim of the study was to examine the effects of a single session of EA on pain intensity and body sway during postural tasks. Method Eighty adults with LBP and pain intensity equal to or greater than 4 (0-10 scale were randomly allocated (1:1 to EA group (EAG or placebo group (PG. Initially, the level of pain intensity was assessed. Next, participants stood still on a force plate either with feet in parallel or in semi-tandem and with eyes open or closed. Then, the EAG was treated with EA for 20 min and the PG was treated with detuned ultrasound. After the treatment, pain intensity was assessed again and the postural test was repeated. Pain intensity was the primary outcome and center of pressure sway area and speed were the secondary outcomes measured. Results Results revealed that pain intensity decreased in both groups after treatment, but decreased more in the EAG. For postural control, no effect of treatment and no interaction between treatment and postural condition on body sway were found. Conclusion Those findings indicate that EA is better than placebo to reduce pain, but neither treatment has any effect on postural control.

  9. Single session imaging of cerebellum at 7 Tesla: obtaining structure and function of multiple motor subsystems in individual subjects.

    Directory of Open Access Journals (Sweden)

    Melissa A Batson

    Full Text Available The recent increase in the use of high field MR systems is accompanied by a demand for acquisition techniques and coil systems that can take advantage of increased power and accuracy without being susceptible to increased noise. Physical location and anatomical complexity of targeted regions must be considered when attempting to image deeper structures with small nuclei and/or complex cytoarchitechtonics (i.e. small microvasculature and deep nuclei, such as the brainstem and the cerebellum (Cb. Once these obstacles are overcome, the concomitant increase in signal strength at higher field strength should allow for faster acquisition of MR images. Here we show that it is technically feasible to quickly and accurately detect blood oxygen level dependent (BOLD signal changes and obtain anatomical images of Cb at high spatial resolutions in individual subjects at 7 Tesla in a single one-hour session. Images were obtained using two high-density multi-element surface coils (32 channels in total placed beneath the head at the level of Cb, two channel transmission, and three-dimensional sensitivity encoded (3D, SENSE acquisitions to investigate sensorimotor activations in Cb. Two classic sensorimotor tasks were used to detect Cb activations. BOLD signal changes during motor activity resulted in concentrated clusters of activity within the Cb lobules associated with each task, observed consistently and independently in each subject: Oculomotor vermis (VI/VII and CrusI/II for pro- and anti-saccades; ipsilateral hemispheres IV-VI for finger tapping; and topographical separation of eye- and hand- activations in hemispheres VI and VIIb/VIII. Though fast temporal resolution was not attempted here, these functional patches of highly specific BOLD signal changes may reflect small-scale shunting of blood in the microvasculature of Cb. The observed improvements in acquisition time and signal detection are ideal for individualized investigations such as

    Purpose. The comparative efficacy of transcatheter arterial chemoembolization (TACE) and percutaneous ethanol injection (PEI) in the treatment of hepatocellular carcinoma (HCC) was investigated. Methods. Two hundred and sixty consecutive patients were retrospectively analyzed: 156 had received between one and six chemoembolization sessions at 3-month intervals, 33 had had PEI, and the remaining 71 patients refused any treatment. The follow-up ranged from 3 to 36 months. Survival rates were statistically analyzed by life-table analysis. Results. Patients' survival was affected by the number of nodules and by the Child's and Okuda's classes; no relationship was found between survival rates and the histologic grade or vascular supply of the tumor. In the case of a single lesion of Okuda's class I, TACE was more effective than PEI. In multifocal HCC, TACE was better than no treatment in Okuda's class I and Child's class A. Conclusion. We suggest TACE as the treatment of choice in Child A or Okuda I patients with multifocal HCCs; it seems of little help in Child B-C or Okuda II-III patients

    2015-12-01

    Blood-injection-injury (BII) phobia is a chronic and debilitating disorder, which has largely been neglected in the child literature. The present paper briefly reviews the aetiology of specific phobias with particular attention to BII and provides an integrated developmental model of this disorder in youth. Evidence-based treatments for child-specific phobias are discussed, and the development of a modified one session treatment (OST) approach to enhance treatment outcomes for BII phobia in children and adolescents is described. This approach is illustrated in two children with a primary diagnosis of BII phobia. The cases illustrate the unique challenges associated with treating BII in youth and the need for a modified intervention. Modifications included addressing the role of pain (e.g., psychoeducation, more graduated exposure steps) and disgust (e.g., disgust eliciting exposure tasks) in the expression of the phobia and fainting in the maintenance of this phobia. Moreover, it is recommended that parents be more actively involved throughout treatment (e.g., education session prior to OST, contingency management training, guidance regarding planning exposure tasks following treatment) and for families to participate in a structured e-therapy maintenance programme post-treatment.

    2017-01-01

    Context: There is a paucity of systematic data reflecting the practice of electroconvulsive therapy (ECT) from developing countries. Aim: We aimed to identify the number of ECT sessions required to yield response and gender diffeferences in the number of sessions across various diagnostic categories. Setting and Design: A record-based study from a teaching cum tertiary care hospital in South India. Subjects and Methods: Case records of patients who received modified ECT from January 2011 to January 2016 were reviewed. The sociodemographic details and ECT-related data were collected. Psychiatric diagnoses were ascertained as per the International Classification of Diseases, 10th Revision criteria. Statistical Analysis Used: Kruskal–Wallis test and Mann–Whitney U-test. Results: Among 148 patients, 82 (55.4%) had mood disorder (bipolar disorder and recurrent depressive disorder), 43 (29.1%) had schizophrenia, and 22 (14.9%) had other acute and transient psychotic disorders (ATPDs). Patients with mood disorders, schizophrenia, and other ATPD received 7.3 (± 3.8), 9.7 (± 6.1), and 5.4 (± 2.0) ECT sessions, respectively, to achieve response. There was no gender difference in the number of sessions received. Conclusion: Our findings show that number of ECT sessions required to yield response may be disorder-specific. Gender does not influence the ECT dose requirement. Variations in ECT parameters across settings may limit the generalizability of results. PMID:28694625

    The primary aim of the study was to assess the feasibility of incorporating a single-session meditation-training program into the daily activities of healthy employees of a tertiary-care academic medical center. The study also assessed the most preferred duration of meditation and the effect of the meditation program on perceived stress, anxiety, and overall quality of life (QOL). Seventeen healthy clinic employees were recruited for this study. After an initial group instruction session covering basic information about meditation, Paced Breathing Meditation (PBM) was taught to the participants. Participants were instructed to self-practice meditation with the help of a DVD daily for a total of 4 weeks. The DVD had three different programs of 5, 15, and 30 minutes with a menu option to choose one of the programs. (1) Patient diary, (2) Perceived Stress Scale (PSS), (3) Linear Analogue Self-Assessment (LASA), (4) Smith Anxiety Scale (SAS). Primary outcome measures were compared using the paired t-test. All participants were female; median age was 48 years (range 33-60 y). The 5-minute meditation session was practiced by 14 participants a total of 137 times during the 4-week trial period, the 15-minute session by 16 participants a total of 223 times, and the 30-minute session by 13 participants 71 times. The median number of days practiced was 25 (range 10-28 d); the average total time practiced was 394 minutes (range 55-850 min). After 4 weeks of practice, the scores of the following instruments improved significantly from baseline: PSS (P meditation in a single training session to health care employees. The study shows that 15 minutes once or twice a day is the most feasible duration of meditation practice. The study also provides promising preliminary efficacy data of this program for improving stress, anxiety, and QOL.

    Full Text Available Objective. The main goal of the present study was to investigate the xanthine oxidase (XO activity in metabolic syndrome in subjects submitted to a single exercise session. We also investigated parameters of oxidative and inflammatory status. Materials/Methods. A case-control study (9 healthy and 8 MS volunteers was performed to measure XO, superoxide dismutase (SOD, glutathione peroxidase activities, lipid peroxidation, high-sensitivity C-reactive protein (hsCRP content, glucose levels, and lipid profile. Body mass indices, abdominal circumference, systolic and diastolic blood pressure, and TG levels were also determined. The exercise session consisted of 3 minutes of stretching, 3 minutes of warm-up, 30 minutes at a constant dynamic workload at a moderate intensity, and 3 minutes at a low speed. The blood samples were collected before and 15 minutes after the exercise session. Results. Serum XO activity was higher in MS group compared to control group. SOD activity was lower in MS subjects. XO activity was correlated with SOD, abdominal circumference, body mass indices, and hsCRP. The single exercise session reduced the SOD activity in the control group. Conclusions. Our data support the association between oxidative stress and risk factors for cardiovascular diseases and suggest XO is present in the pathogenesis of metabolic syndrome.

    Photodynamic therapy has been described as an effective therapeutic option in selected cases of anogenital lichen sclerosus that are refractory to first-line treatments. However, procedure-related pain is a limiting factor in patient adherence to treatment. The authors report the case of a 75-year-old woman with highly symptomatic vulvar lichen sclerosus, successfully treated with photodynamic therapy. An inhaled 50% nitrous oxide/oxygen premix was administered during sessions, producing a pain-relieving, anxiolytic, and sedative effect without loss of consciousness. This ready-to-use gas mixture may be a well-tolerated and accepted alternative to classical anesthetics in Photodynamic therapy, facilitating patients' adherence to illumination of pain-prone areas.

    Full Text Available This study aimed to investigate the acute effects of passive static and ballistic stretching on maximal repetition performance during a resistance training session (RTS. Nine male subjects underwent three experimental conditions: ballistic stretching (BS; passive static stretching (PSS; and a specific warm-up (SW. The RTS was composed of three sets of 12RM for the following exercises: leg press 45 (LP, leg extension (LE, leg curl (LC, and plantar flexors (PF. Performance of six sessions was assessed 48 hours apart. The first visit consisted of a familiarization session including stretching methods and exercises used in the RTS. On the second and third visit, a strength test and retest were performed. During the fourth to the sixth visit, the volunteers randomly performed the following protocols: BS+RTS; PSS+RTS; or SW+RTS. For the sum of the RM number of each three-set exercise, significant differences were found between PSS vs. SW for the LP (p = 0.001; LE (p = 0.005; MF (p = 0.001; and PF (p = 0.038. For the comparison between the methods of stretching PSS vs. BS, significant differences were found only for the FP (p = 0.019. When analyzing the method of stretching BS vs. SW, significant differences were found for the LP (p = 0.014 and MF (p = 0.002. For the total sum of the RM number of three sets of the four exercises that composed the RTS, significant differences were observed (p < 0.05 in the following comparisons: PPS vs. SW (p = 0.001, PPS vs. BS (p = 0.008, and BS vs. SW (p = 0.002. Accordingly, the methods of passive static and ballistic stretching should not be recommended before a RTS.

  20. Combined local and systemic bleomycin administration in electrochemotherapy to reduce the number of treatment sessions

    2016-03-01

    Full Text Available Electrochemotherapy (ECT, a medical treatment widely used in human patients for tumor treatment, increases bleomycin toxicity by 1000 fold in the treated area with an objective response rate of around 80%. Despite its high response rate, there are still 20% of cases in which the patients are not responding. This could be ascribed to the fact that bleomycin, when administered systemically, is not reaching the whole tumor mass properly because of the characteristics of tumor vascularization, in which case local administration could cover areas that are unreachable by systemic administration.

    Full Text Available This study aimed to analyze the acute effects of a single session of a community-based group exercise program combining step aerobics and bodyweight resistance exercise on blood pressure in healthy young adult women. Twentythree healthy young adult women (aged 31.57 ± 7.87 years participated in two experimental sessions (exercise and control in a crossover study design. Blood pressure was monitored before, immediately after and at 10, 20 and 30 min of recovery. The exercise session consisted of four phases: 1 a warm-up (5 min of dance aerobics; 2 aerobic exercise training (30 min of step aerobics; 3 resistance exercise training (six sets of 12 repetitions of three bodyweight exercises in a circuit mode, 10 min; and 4 a cool-down (5 min of breathing and flexibility exercises; totaling 50 min of duration. Systolic blood pressure after exercise was significantly lower compared to control at the 10th min (-10.83 ± 2.13 vs. -2.6 ± 2.13 mmHg; p = 0.009, 20th min (-11.26 ± 2.13 vs. -3.04 ± 2.13 mmHg; p = 0.009 and 30th min of recovery (-10.87 ± 2.39 vs. -0.48 ± 2.39 mmHg; p = 0.004. A single session of a community-based group exercise program combining step aerobics and bodyweight resistance exercise was effective in inducing significant post-exercise hypotension in healthy young adult women. This type of low-cost exercise interventions may have an important role in the prevention of cardiovascular diseases and in community health promotion.

    Full Text Available Background and Purpose: Repetitive transcranial magnetic stimulation (rTMS induces widespread changes in brain connectivity. As the network topology differences induced by a single session of rTMS are less known we undertook this study to ascertain whether the network alterations had a small-world morphology using multi-modal graph theory analysis of simultaneous EEG-fMRI.Method: Simultaneous EEG-fMRI was acquired in duplicate before (R1 and after (R2 a single session of rTMS in 14 patients with Writer’s Cramp (WC. Whole brain neuronal and hemodynamic network connectivity were explored using the graph theory measures and clustering coefficient, path length and small-world index were calculated for EEG and resting state fMRI (rsfMRI. Multi-modal graph theory analysis was used to evaluate the correlation of EEG and fMRI clustering coefficients.Result: A single session of rTMS was found to increase the clustering coefficient and small-worldness significantly in both EEG and fMRI (p < 0.05. Multi-modal graph theory analysis revealed significant modulations in the fronto-parietal regions immediately after rTMS. The rsfMRI revealed additional modulations in several deep brain regions including cerebellum, insula and medial frontal lobe.Conclusion: Multi-modal graph theory analysis of simultaneous EEG-fMRI can supplement motor physiology methods in understanding the neurobiology of rTMS in vivo. Coinciding evidence from EEG and rsfMRI reports small-world morphology for the acute phase network hyper-connectivity indicating changes ensuing low-frequency rTMS is probably not “noise”.

    Expiratory muscle strength training (EMST) is a rehabilitative program that has been tested for outcomes related to respiratory muscle strength, cough, swallow, and voice function in healthy young adult, elderly individuals, and in patients with progressive neurodegenerative disease. Because EMST has been used in patient care, the associated cardiovascular responses during EMST are of importance. This study investigated the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and oxygen saturation (SpO(2)) during one session of EMST in healthy, young adults as a preliminary study of device safety. Thirty-one participants completed a single session of 25 trials with the EMST device. Valsalva maneuvers were performed at the beginning and at the end of the EMST trials for task comparison. The SBP, DBP, HR, and SpO(2) were recorded at the baseline and after completing the following tasks: a Valsalva maneuver, 12 trials using the EMST device, 13 trials using the EMST device, and 5 min of rest following the EMST session. A mixed linear model tested for changes across the six time points. The results indicated no significant change of SBP, DBP, HR, or SpO(2) during or following the EMST trials or after performing the Valsalva maneuver. The results suggest that EMST does not elicit significant fluctuations of blood pressure, HR, and SpO(2) in healthy young adults even when considering the effects of covariates on the outcomes measures.

    Background Poor sleep quality is associated with adverse effects on health outcomes. It is not clear whether exercise can improve sleep quality and whether intensity of exercise affects any of the effects. Methods Fifteen healthy, non-obese (body mass index = 24.4 ± 2.1 kg/m2, mean ± SD), sedentary (exercise on no more than 3 times/week) older women (66.1 ± 3.9 years) volunteered for the study. Peak oxygen consumption (VO2peak) was evaluated using a graded exercise test on a treadmill with a metabolic cart. Following a 7-day baseline period, each participant completed two exercise sessions (separated by 1 week) with equal caloric expenditure, but at different intensities (60% and 45% VO2peak, sequence randomized) between 9:00 and 11:00 am. A wrist ActiGraph monitor was used to assess sleep at baseline and two nights following each exercise session. Results The average duration of the exercise was 54 and 72 min, respectively at 60% (moderate-intensity) and 45% VO2peak (light-intensity). Wake time after sleep onset was significantly shorter (p = 0.016), the number of awakenings was less (p = 0.046), and total activity counts were lower (p = 0.05) after the moderate-intensity exercise compared to baseline no-exercise condition. Conclusion Our data showed that a single moderate-intensity aerobic exercise session improved sleep quality in older women. PMID:25685605

    This study evaluated a 90-min single session school-based body image intervention (Dove Confident Me: Single Session), and investigated if delivery could be task-shifted to teachers. British adolescents (N = 1707; 11-13 years; 50.83% girls) participated in a cluster randomised controlled trial [lessons as usual control; intervention teacher-led (TL); intervention researcher-led (RL)]. Body image, risk factors, and psychosocial and disordered eating outcomes were assessed 1-week pre-intervention, immediate post-intervention, and 4-9.5 weeks follow-up. Multilevel mixed-models showed post-intervention improvements for intervention students relative to control in body esteem (TL; girls only), negative affect (TL), dietary restraint (TL; girls only), eating disorder symptoms (TL), and life engagement (TL; RL). Awareness of sociocultural pressures increased at post-intervention (TL). Effects were small-medium in size (ds 0.19-0.76) and were not maintained at follow-up. There were no significant differences between conditions at post or follow-up on body satisfaction, appearance comparisons, teasing, appearance conversations and self-esteem. The intervention had short-term benefits for girls' body image and dietary restraint, and for eating disorder symptoms and some psychosocial outcomes among girls and boys. A multi-session version of the intervention is likely to be necessary for sustained improvements. Teachers can deliver this intervention effectively with minimal training, indicating broader scale dissemination is feasible. ISRCTN16782819. Copyright © 2015 The Authors. Published by Elsevier Ltd..

    Full Text Available Background: Transcranial direct-current stimulation (tDCS has been widely studied with the aim of enhancing local synaptic efficacy and modulating the electrical activity of the cortex in patients with neurological disorders. Objective: The purpose of the present study was to determine the effect of a single session of tDCS regarding immediate changes in spatiotemporal gait and oscillations of the center of pressure (30 seconds in children with cerebral palsy (CP. Method: A randomized controlled trial with a blinded evaluator was conducted involving 20 children with CP between six and ten years of age. Gait and balance were evaluated three times: Evaluation 1 (before the stimulation, Evaluation 2 (immediately after stimulation, and Evaluation 3 (20 minutes after the stimulation. The protocol consisted of a 20-minute session of tDCS applied to the primary motor cortex at an intensity of 1 mA. The participants were randomly allocated to two groups: experimental group - anodal stimulation of the primary motor cortex; and control group - placebo transcranial stimulation. Results: Significant reductions were found in the experimental group regarding oscillations during standing in the anteroposterior and mediolateral directions with eyes open and eyes closed in comparison with the control group (p<0.05. In the intra-group analysis, the experimental group exhibited significant improvements in gait velocity, cadence, and oscillation in the center of pressure during standing (p<0.05. No significant differences were found in the control group among the different evaluations. Conclusion: A single session of tDCS applied to the primary motor cortex promotes positive changes in static balance and gait velocity in children with cerebral palsy.

    Full Text Available Vibration training has become a popular method used in professional sports and recreation. In this study, we examined the effect of whole-body vibration training on the central nervous system and muscle excitability in a group of 28 active men. Subjects were assigned randomly to one of two experimental groups with different variables of vibrations. The chronaximetry method was used to evaluate the effect of a single session of whole-body vibration training on the excitability of the rectus femoris and brachioradialis muscles. The examination of the fusing and flickering frequencies of the light stimulus was performed. An increase in the excitability of the quadriceps femoris muscle due to low intensity vibrations (20 Hz frequency, 2 mm amplitude was noted, and a return to the initial values was observed 30 min after the application of vibration. High intensity vibrations (60 Hz frequency, 4 mm amplitude caused elongations of the chronaxy time; however, these differences were not statistically significant. Neither a low intensity vibration amplitude of 2 mm (frequency of 20 Hz nor a high intensity vibration amplitude of 4 mm (frequency of 60 Hz caused a change in the excitability of the central nervous system, as revealed by the average frequency of the fusing and flickering of the light stimulus. A single session of high intensity whole-body vibration did not significantly decrease the excitability of the peripheral nervous system while the central nervous system did not seem to be affected.

    To evaluate the time course of fatigue in torque output and oxygen uptake during isometric subtetanic neuromuscular electrical stimulation (NMES) to facilitate the design of NMES-based rehabilitation protocols that can accumulate a defined aerobic exercise volume within a given time period. Single-arm intervention study with within-subject comparisons. University research laboratory. Volunteer sample of healthy men (N=11; mean age, 34.2 ± 11.5 y; range, 19-53 y; body mass, 79.1 ± 11.7 kg; range, 58-100 kg). A single 30-minute session of continuous bilateral isometric quadriceps NMES at 4 Hz evoking a mean twitch amplitude of 12% of the maximum voluntary contraction. Whole body oxygen consumption rate (V˙o2), and evoked torque were measured simultaneously throughout. Mean increment in V˙o2 was 596 ± 238 mL/min, and average exercise intensity during the session was 3 ±.47 metabolic equivalents. The V˙o2 and torque declined slowly at a rate of -.54%±.31% and -.47%±.57% per minute, respectively. Despite having a higher incremental V˙o2, the observed fatigue rate was considerably less than that previously reported during intermittent isometric tetanic stimulation, suggesting that subtetanic isometric NMES is more sustainable for exercise interventions aimed at accumulating a therapeutic aerobic exercise volume.

    Full Text Available Abstract Background Cortical excitability changes as well as imbalances in excitatory and inhibitory circuits play a distinct pathophysiological role in chronic tinnitus. Repetitive transcranial magnetic stimulation (rTMS over the temporoparietal cortex was recently introduced to modulate tinnitus perception. In the current study, the effect of theta-burst stimulation (TBS, a novel rTMS paradigm was investigated in chronic tinnitus. Twenty patients with chronic tinnitus completed the study. Tinnitus severity and loudness were monitored using a tinnitus questionnaire (TQ and a visual analogue scale (VAS before each session. Patients received 600 pulses of continuous TBS (cTBS, intermittent TBS (iTBS and intermediate TBS (imTBS over left inferior temporal cortex with an intensity of 80% of the individual active or resting motor threshold. Changes in subjective tinnitus perception were measured with a numerical rating scale (NRS. Results TBS applied to inferior temporal cortex appeared to be safe. Although half of the patients reported a slight attenuation of tinnitus perception, group analysis resulted in no significant difference when comparing the three specific types of TBS. Converting the NRS into the VAS allowed us to compare the time-course of aftereffects. Only cTBS resulted in a significant short-lasting improvement of the symptoms. In addition there was no significant difference when comparing the responder and non-responder groups regarding their anamnestic and audiological data. The TQ score correlated significantly with the VAS, lower loudness indicating less tinnitus distress. Conclusion TBS does not offer a promising outcome for patients with tinnitus in the presented study.

    There is little research on short-term treatments for borderline personality disorder (BPD). While the core changes may occur only in long-term treatments, short-term treatments may enable the study of early generic processes of engagement in therapy and thus inform about effective treatment components. It was shown that a 10-session version of a psychiatric treatment was effective in reducing borderline symptoms at the end of this treatment [Kramer, U., Kolly, S., Berthoud, L., Keller, S., Preisig, M., Caspar, F., … Despland, J.-N. (2014). Effects of motive-oriented therapeutic relationship in a ten-session general psychiatric treatment for borderline personality disorder: A randomized controlled trial. Psychotherapy and Psychosomatics, 83, 176-186.]. Also, it was demonstrated in a randomized design that adding the motive-oriented therapeutic relationship (MOTR), following an individualized case formulation based on Plan Analysis, further increased general outcome after session 10 and had a positive effect on the early changes in self-esteem and alliance. The present study focuses on the follow-up period after this initial treatment, examining treatment density and outcomes after 6 months and service utilization after 12 months. Outcome was measured using the OQ-45. Results on a sub-sample of N = 40 patients with available OQ-45 data at follow-up (n = 21 for MOTR-treatment, n = 19 for comparison treatment) showed maintenance of gains over the follow-up period, which did not differ between both conditions. It appeared for this sample that MOTR treatments, while using the same number of sessions, lasted more weeks (i.e., lower treatment density, defined as the number of sessions per week), when compared to the treatments without MOTR. Density marginally predicted symptom reduction at follow-up. Patients in MOTR treatments had a greater likelihood of entering structured psychotherapy after the initial sessions than patients in the comparison

    The aim of this study was to assess the effect of the daily practice of a yoga therapy program learnt during a single session of an integrated yoga intervention that was developed by us as a stress management tool for school employees. Ninety school employees. Case-control study. Three months after the intervention, the subjects were assigned to a daily practice group (case: n=43) and a nonconsecutive daily practice group (control: n=47) according to their daily practice level of the yoga therapy program. The subjects participated in a stress management education program based on an integrated yoga therapy session. The program included psychological education and counseling about stress management and yoga theories, as well as the practices of asanas, pranayama, relaxation, and cognitive structure based on Indian philosophy. Assessments were performed before and after the program using the Subjective Units of Distress for mind and body and the Two-Dimensional Mood Scale. The General Health Questionnaire 28 (GHQ28) was used to assess the mental health state before the intervention and at 3 months after the program. The subjects showed significant increases in their levels of calmness, comfort, and cheerfulness (pstress (pstress and that the mental health of school employees was promoted by the daily practice of the yoga therapy program.

    Local ablative therapies such as stereotactically guided single-dose radiotherapy or helical intensity-modulated radiotherapy (tomotherapy) with high single-doses are successfully applied in many centers in patients with liver metastasis not suitable for surgical resection. This study presents results from more than 10 years of clinical experience and evaluates long-term outcome and efficacy of this therapeutic approach. From 1997 to 2009 a total of 138 intrahepatic tumors of 90 patients were irradiated with single doses of 17 to 30 Gy (median dose 24 Gy). Median age of the patients was 64 years (range 31–89 years). Most frequent underlying tumor histologies were colorectal adenocarcinoma (70 lesions) and breast cancer (27 lesions). In 35 treatment sessions multiple targets were simultaneously irradiated (up to four lesions at once). Local progression-free (PFS) and overall survival (OS) after treatment were investigated using uni- and multiple survival regression models. Median overall survival of all patients was 24.3 months. Local PFS was 87%, 70% and 59% after 6, 12 and 18 months, respectively. Median time to local progression was 25.5 months. Patients with a single lesion and no further metastases at time of RT had a favorable median PFS of 43.1 months according to the Kaplan-Meier estimator. The type of tumor showed a statistical significant influence on local PFS, with a better prognosis for breast cancer histology than for colorectal carcinoma in uni- and multiple regression analysis (p = 0.05). Multiple regression analysis revealed no influence of planning target volume (PTV), patient age and radiation dose on local PFS. Treatment was well tolerated with no severe adverse events. This study confirms safety of SBRT in liver lesions, with 6- and 12 months local control of 87% and 70%. The dataset represents the clinical situation in a large oncology setting, with many competing treatment options and heterogeneous patient characteristics

  18. Quantitative Review Finds No Evidence of Cognitive Effects in Healthy Populations From Single-session Transcranial Direct Current Stimulation (tDCS).

    Over the last 15-years, transcranial direct current stimulation (tDCS), a relatively novel form of neuromodulation, has seen a surge of popularity in both clinical and academic settings. Despite numerous claims suggesting that a single session of tDCS can modulate cognition in healthy adult populations (especially working memory and language production), the paradigms utilized and results reported in the literature are extremely variable. To address this, we conduct the largest quantitative review of the cognitive data to date. Single-session tDCS data in healthy adults (18-50) from every cognitive outcome measure reported by at least two different research groups in the literature was collected. Outcome measures were divided into 4 broad categories: executive function, language, memory, and miscellaneous. To account for the paradigmatic variability in the literature, we undertook a three-tier analysis system; each with less-stringent inclusion criteria than the prior. Standard mean difference values with 95% CIs were generated for included studies and pooled for each analysis. Of the 59 analyses conducted, tDCS was found to not have a significant effect on any - regardless of inclusion laxity. This includes no effect on any working memory outcome or language production task. Our quantitative review does not support the idea that tDCS generates a reliable effect on cognition in healthy adults. Reasons for and limitations of this finding are discussed. This work raises important questions regarding the efficacy of tDCS, state-dependency effects, and future directions for this tool in cognitive research. Copyright © 2015 Elsevier Inc.

    Timing deficits can have a negative impact on the lives of survivors post-chronic stroke. Studies evaluating ways to improve timing post stroke are scarce. The goal of the study was to evaluate the impact of a single session of haptic guidance (HG) and error amplification (EA) robotic training interventions on the improvement of post-stroke timing accuracy. Thirty-four survivors post-chronic stroke were randomly assigned to HG or EA. Participants played a computerized pinball-like game with their affected hand positioned in a robot that either helped them perform better (HG) or worse (EA) during the task. A baseline and retention phase preceded and followed HG and EA, respectively, in order to assess their efficiency at improving absolute timing errors. The impact of the side of the stroke lesion on the participants' performance during the timing task was also explored for each training group. An improvement in timing performance was only noted following HG (8.9 ± 4.9 ms versus 7.8 ± 5.3 ms, p = 0.032). Moreover, for the EA group only, participants with a left-sided stroke lesion showed a worsening in performance as compared to those with a right-sided stroke lesion (p = 0.001). Helping survivors post-chronic stroke perform a timing-based task is beneficial to learning. Future studies should explore longer and more frequent HG training sessions in order to further promote post stroke motor recovery. Implications for Rehabilitation Timing is crucial for the accomplishment of daily tasks. The number of studies dedicated to improving timing is scarce in the literature, even though timing deficits are common post stroke. This innovative study evaluated the impact of a single session of haptic guidance-HG and error amplification-EA robotic training interventions on improvements in timing accuracy among survivors post chronic stroke. HG robotic training improves timing accuracy more than EA among survivors post chronic stroke.

    In the summary session, possible international activities in the field of basic studies on high-temperature engineering were discussed within the framework of the OECD/NEA Nuclear Science Committee (NSC). It was recommended to include topics relevant to fission-product behaviour and safety issues of HTGR in next meeting, in addition to the topics discussed in this meeting. The chairperson of the last session summarised the recommendations to be presented to the NSC into the following five topics as possible international activities: - Basic studies on behaviour of irradiated graphite/carbon and ceramic materials including their composites under both operation and storage conditions. - Development of in-core material characterisation and instrumentation methods. - Improvement in material properties through high-temperature irradiation. - Basic studies on HTGR fuel fabrication and performance including fission-product release. - Basic studies on safety issues of HTGR. It was also recommended that a further information exchange meeting focused on the organisation of the interactive collaboration activity with regard to the above topics be planned in 2003, tentatively in Oarai, Japan.

    Individuals with Inflammatory Bowel Disease (IBD) have poor knowledge regarding the implications of disease for fertility and pregnancy. Previous studies suggest that this poor knowledge adversely influences reproductive decision making. To examine the effect of a single group education session on IBD-specific reproductive knowledge in subjects with IBD. People with IBD attending an educational event were invited to complete the CCPKnow questionnaire, testing reproductive knowledge in IBD, before and after an evidenced based presentation on this topic delivered by a Gastroenterologist. Of 248 attendees, 155 participated; 69% female, mean age 40.3years. CCPKnow scores (maximum 17) were low at baseline and increased significantly post education (mean 5.4 pre vs. 14.5 post education; p<0.0001). A large majority (65.1%) of subjects had "poor" (score <8) knowledge at baseline, compared with only 1.9% after education (p<0.0001). Whilst all subareas of knowledge improved after education, the most important improvement was in attitudes toward medication use in pregnancy: 33.5% of subjects indicated at baseline that women should avoid all drugs in pregnancy compared with only 1.2% post education (p<0.0001). A single group-delivered education event focussed on reproductive issues in IBD can dramatically improve patient knowledge. This has the potential to change reproductive behaviour and may reduce voluntary childlessness resulting from misperceptions amongst individuals with IBD. Crown Copyright © 2013.

    The effectiveness of endodontic treatment regarding the number of sessions to complete the therapy is still controversial. The aim of this study was to conduct an overview of published systematic reviews (SRs) comparing endodontic treatment in single and multiple visits. A systematic search was performed in the electronic databases MEDLINE/PubMed and Cochrane Central Register of Controlled Trials until August 18, 2016, without language restriction. The eligibility criteria were as follows: (1) SRs and (2) a focus on endodontic techniques in single or multiple visits. The phases of eligibility and analysis of risk of bias were conducted by 2 or 3 independent and calibrated examiners, and a fourth examiner was consulted to resolve inconsistencies. Assessment of Multiple Systematic Reviews was used to evaluate the risk of bias of the included SRs, which were assessed according to the risk to develop knowledge and the existing knowledge gap. The main characteristics including healing rates, success, and clinical complications during and after endodontic treatment were extracted from the SRs. From the 20 SRs initially identified, 8 were included in the analysis. Of these, 6 SRs showed low to moderate risk of bias and were suitable as strong clinical evidence on the topic. Overall analysis indicated that single and multiple visits showed similar repair or success rates regardless of the precondition of the pulp and periapex. The apical periodontitis subgroup showed a slight positive trend toward a decreased incidence of postoperative complications and a higher effectiveness and efficiency for a single session. Based on the risk of bias, the current level of evidence for this clinical approach is high. Copyright © 2017 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    2016-06-15

    Purpose: The incidence of peripheral neuropathy has risen with increased utilization of SAbR. There is no consensus regarding the dose-tolerance of the peripheral nervous system. In 2015, we commenced an investigation to test the hypotheses that single-session irradiation to the pig spinal nerves exhibit a similar dose-tolerance as that of the spinal cord and that a dose-length effect exists. This work evaluates the direct application of small animal NTCP models to both large animal spinal cord and preliminary peripheral nerve data. Methods: To date, 16 of 25 Yucatan minipigs have received single-session SAbR to a 1.5cm length and 4 of 25 have received irradiation to a 0.5cm length of left-sided C6-C8 spinal nerves. Toxicity related gait change has been observed in 13 animals (9 from the long length group and 4 from the short). This preliminary data is overlaid on several dose-response models which have been fit to rodent spinal cord tolerance experiments. Model parameters define a toxicity profile between a completely serial or parallel behaving organ. Adequacy of model application, including how length effects are handled, to published minipig spinal cord dose-response data and to preliminary peripheral nerve response data was evaluated through residual analysis. Results: No rodent-derived dose-response models were directly applicable to all pig data for the different lengths irradiated. Several models fit the long-length irradiated spinal cord data well, with the more serial-like models fitting best. Preliminary data on the short-length irradiation suggests no length effect exists, disproving our hypothesis. Conclusion: Direct application of small-animal NTCP models to pig data suggests dose-length effect predictions from small animal data may not translate clinically. However, the small animal models used have not considered dose heterogeneity and it is expected that including the low-to-mid dose levels in the penumbral region will improve this match. This work

    Gait and balance disorders are among the most common causes of falls in older adults. Most falls occur as a result of unexpected hazards while walking. In order to improve the effectiveness of current fall-prevention programs, new balance training paradigms aim to strengthen the control of the compensatory responses required after external perturbations. The aim of this study was to analyze the adaptions of reactive and proactive strategies to control stability after repeated exposures to waist-pull perturbations delivered while walking. Eight healthy young subjects participated in a single training session with the Active Tethered Pelvic assisted Device (A-TPAD). Participants were exposed to repeated multi-directional perturbations of increasing intensity. The Antero-Posterior (AP) and Medio-Lateral (ML) Base of Support (BoS) and Margin of Stability (MoS) during the response to diagonal perturbations were compared before and after the training. Results showed that participants adapted both the reactive and proactive strategies to control walking balance by significantly increasing their pre- and post-perturbation stability. The changes were principally accounted for by an increment of the AP BoS and MoS and a reduction of ML BoS. This improved their ability to react to a diagonal perturbation. We envision that this system can be used to develop a perturbation-based gait training aimed at improving balance and control of stability during walking, thus reducing fall risk.

    To analyze single session, intrauser reliability of a Scheimpflug device for anterior chamber (AC) and corneal parameters. In this observational study, 100 normal candidates underwent Scheimpflug analysis with Sirius 3D Rotating Scheimpflug Camera and Topography System (Costruzione Strumenti Oftalmici, Italy). Two scans in dark room conditions were performed by the same experienced user. The candidates were asked to keep both eyes closed for 5min before the scans. Exclusion criteria were previous ocular surgery, corneal scarring and anterior segment/posterior segment anomalies. Only the right eyes were used for the analysis. Both corneal (central, minimum, and apical thickness, volume, horizontal visible iris diameter, and apical curvature) and anterior chamber (volume, depth, angle, horizontal diameter) measurements were evaluated. There was no difference in the means of repeated measurements (p>0.05, ANOVA). Intraclass correlations between the measures were high and ranged from 0.995-0.997 for corneal to 0.964-0.997 for anterior chamber (AC) parameters. The precision of repeatability measures (1.96×Sw) was approximately 5μ for the central and minimum corneal thickness, 8μ for the apical corneal thickness, 0.06mm for AC (anterior chamber) depth and less than 2° for the AC angle. Sirius Scheimpflug system has high repeatability for both corneal and AC parameters in normal eyes. Copyright © 2015 Spanish General Council of Optometry. Published by Elsevier Espana.

    To investigate the therapeutic effect of extracorporeal shockwave therapy (ESWT) according to treatment session on gastrocnemius muscle spasticity in children with spastic cerebral palsy (CP). Twelve children with spastic CP underwent 1 ESWT and 2 sham ESWT sessions for gastrocnemius (group 1) or 3 ESWT sessions (group 2) once per week for 3 weeks. Modified Ashworth Scale (MAS) score, passive range of motion (PROM) of the ankle plantar-flexor muscles with knee extension, and median red pixel intensity (RPI) of color histogram of medial gastrocnemius on real-time sonoelastography (RTS) were measured before ESWT, immediately after the first and third ESWT, and at 4 weeks after the third ESWT. Mean ankle PROM was significantly increased whereas as mean ankle MAS and median gastrocnemius RPI were significantly decreased in both groups after the first ESWT. Clinical and RTS parameters before ESWT were not significantly different from those immediately after the third ESWT or at 4 weeks after the third ESWT in group 1. However, they were significantly different from those immediately after the third ESWT or at 4 weeks after the third ESWT in group 2. Mean ankle PROM, mean ankle MAS, and median gastrocnemius RPI in group 2 were significantly different from that in group 1 at 4 weeks or immediately after the third ESWT. The therapeutic effect of ESWT on spastic medial gastrocnemius in children with spastic CP is dependent on the number of ESWT sessions.

    Full Text Available Few studies have been undertaken to develop cognitive functional improvement-focused exercise programs and determine their effect. The objectives of this study were to evaluate the effects of a cognitive enhancement fitness program (CEFP on short-term memory and serum brain-derived neurotrophic factor (BDNF levels according to the cognitive state in middle-aged women. A total of 30 healthy volunteers aged 40–59 years were divided into two groups, that is, a mild cognitive impairment (MCI group and a non-MCI group based on results from the Korean Dementia Screening Questionnaire. A single-session CEFP was conducted over 50 min and consisted of four parts: warm-up, low intensity interval circulation dance exercises, moderate intensity resistance exercises using elastic bands, and cool-down. Serum BDNF levels were measured by ELISA and short-term memory determined by forward digit/word span test was assessed before and after CEFP. After CEFP, forward digit/word span test scores and BDNF levels increased to median 119.2%/115.1% and 118.7%, respectively. After CEFP, the MCI and non-MCI groups produced higher forward digit span test scores (from 6.7 ± 1.5 to 7.5 ± 1.4 points, p = 0.023 and from 6.2 ± 2.0 to 7.0 ± 2.1 points, P=0.011, respectively. After CEFP, forward word span scores and BDNF levels increased (from 3.5 ± 1.7 to 4.6 ± 1.8 points, p = 0.029 and from 610.8 ± 221.1 to 757.9 ± 267.9 pg/ml, p = 0.017, respectively in non-MCI group only. No group differences were observed between change in short-term memory and change in BDNF. Short-term memory and BDNF levels after CEFP were found to be negatively correlated with age, but pre- to post-intervention changes in short-term memory and BDNF were not. The present study shows that a single, 50-minute CEFP improved short-term memory and increased serum BDNF levels in healthy middle-aged women, especially those without MCI.

    Outcome of pulpectomy in 2 treatment sessions with calcium hydroxide as an intracanal dressing was compared to a procedure comprising instrumentation and root-filling in 1 session. Subjects with a vital pulp condition (N = 256) were recruited to a randomized clinical trial. Outcome parameters included radiographic signs of apical periodontitis and painful symptoms at clinical follow-ups 1 week and 1-3 years after treatment. Of 244 subjects available for final recall, 17 presented with periapical radiolucency. Lesions were evenly distributed among the 2 treatment groups. Postoperative pain recorded 1 week after permanent filling was significantly associated with overfilling (P = .001), with no difference between treatment groups. There was no association with presence of overfilling and radiographic lesion at end point of recall. Study confirms that pulpectomy may be carried out at a high rate of success if due attention is given to aseptic operating procedures, proper instrumentation and filling. Under these conditions an interappointment dressing with calcium hydroxide does not seem to influence outcome.

    Balance and strength training can reduce seniors' fall risk up to 50%. Available evidence suggests that acute bouts of neuromuscular and endurance exercise deteriorate postural control. High-intensity endurance training has been successfully applied in different populations. Thus, it seemed valuable to examine the acute effects of high-intensity interval training (HIIT) on neuromuscular performance in seniors and young adults. The acute impact of a HIIT session on balance performance and muscle activity after exercise cessation and during post-exercise recovery was examined in young and old adults. We intended to investigate whether a transient exercise-induced fall-risk may occur in both groups. 20 healthy seniors (age 70 (SD 4) years) and young adults (age 27 (SD 3) years) were examined on 3 days. After exhaustive ramp-like treadmill testing in order to determine maximal heart rate (HRmax) on the first day, either a 4 × 4 min HIIT at 90% of HRmax or a control condition (CON) was randomly performed on the second and third day, respectively. Balance performance (postural sway) was assessed during single limb stance with open eyes (SLEO) and double limb stance with closed eyes (DLEC). EMG was recorded for the soleus (SOL), anterior tibialis (TIB), gastrocnemius (GM) and peroneus longus (PL) muscles at the dominant leg. All measures were collected before, immediately as well as 10, 30 and 45 min after HIIT and CON, respectively. Compared to CON, HIIT induced significant increases of postural sway immediately after exercise cessation during SLEO in both groups (adults: p HIIT (post: p = 0.003, Δ = +14% sway, 10 min post: p = 0.004, Δ = +18% sway). Muscle activity was increased during SLEO for TIB until 10 min post in seniors (0.008 HIIT in adults (p HIIT training may cause an acute 'open-fall-window' with a transient impairment of balance performance for at least 10 min after exercise cessation in both groups. Occluded vision in seniors seems to prolong this period

    Integrative veterinary medicine, the combination of complementary and alternative therapies with conventional care, is increasingly prevalent in veterinary practice and a focus of clinical instruction in many academic teaching institutions. However, the presenting complaints, therapeutic modalities, and patient population in an integrative medicine service have not been described. A retrospective analysis of 5,195 integrative patient treatment sessions in a veterinary academic teaching hospital demonstrated that patients most commonly received a combination of therapeutic modalities (39% of all treatment sessions). The 274 patients receiving multiple modalities were most frequently treated for neurologic and orthopedic disease (50.7% versus 49.6% of all presenting complaints, resp.). Older neutered or spayed dogs (mean age = 9.0 years) and Dachshunds were treated more often than expected based on general population statistics. Acupuncture, laser therapy, electroacupuncture, and hydrotherapy were frequently administered (>50% patients). Neurologic patients were more likely to receive acupuncture, electroacupuncture, and therapeutic exercises but less likely than orthopedic patients to receive laser, hydrotherapy, or therapeutic ultrasound treatments (P < 0.05). The results suggest that the application of these specific modalities to orthopedic and neurologic diseases should be subjected to increased evidence-based investigations. A review of current knowledge in core areas is presented. PMID:26798552

    The choice between several treatment options for replacing a single missing tooth is influenced by clinical, dentist- and patient-immanent factors. This study aimed to determine the patient factors that would affect the treatment decision to replace a single missing tooth and to assess the satisfaction with several options. 200 volunteers involved (121 females and 79 males) divided into four groups, Group A: consisted of patients with conventional fixed partial dentures or patients with resin bonded fixed partial dentures. Group B: consisted of patients who received removable partial dentures while Group C: consisted of patients who received a single implant supported crown, and a control group D: consisted of patients who received no treatment. Data were collected using a questionnaire. The highest percentage of males within groups (58%) was within the removable prostheses category. The majority of the subjects in the study reported that the main reason for replacing a missing tooth was for esthetic and function. Most important factor affecting the choice between treatment modalities was damaging the neighboring teeth. Pain, post operative sensitivity and dental phobia were important factors in choosing the prosthesis type and affected the control group patients not to have any treatment. The highest satisfaction percentage among groups studied was recorded for dental implants then FPD groups, while the least percentage were in both the control and RPD groups, for all aspects of function, esthetic and speech efficiency. The final choice between FPD, RPD and implant depended on several factors which affected the decision making; among these is cost and patients' awareness of the different treatment options.

    We do not know much about how patients internalize, remember or use psychotherapeutic experiences between psychotherapy sessions and how they use them for change. What happens with in-session-experiences after a session ("inter-session-process") is of main importance for outcome. The inter-session-process describes the work on psychotherapy between sessions. Although inter-session-processes are a central element connecting psychotherapy process and outcome, they remain a neglected area of research. Previous studies examined individual outpatient settings only. This paper gives an overview over theory, instruments for measurement, previous studies and relevance of inter-session-processes for the field of psychotherapy research.

    This study evaluated the effects of alpha/theta neurofeedback on Clinical Personality Accentuations in individuals with alcohol use disorder. Twenty-five males were investigated using a pre-test/post-test design with a waiting-list control group. Participants were randomly assigned either to an experimental group ( n = 13) receiving 12 sessions of neurofeedback twice a week as a treatment adjunct over a period of 6 weeks, or to a control group ( n = 12) receiving treatment as usual. The Inventory of Clinical Personality Accentuations and the NEO-Five-Factor Inventory were applied at pre- and post-test. The neurofeedback protocol focused on enhancement of the EEG alpha (8-12 Hz) and theta (4-7 Hz) and used a visual feedback paradigm. Analyses of covariance showed improvements in Avoidant Personality Accentuation within the experimental group. Our data suggest that 12 sessions of this neurofeedback intervention might be effective in reducing avoidant and stress-related personality traits in patients with alcohol use disorder.

    Does the learning of a balance and stability skill exhibit time-course phases and transfer limitations characteristic of the acquisition and consolidation of voluntary movement sequences? Here we followed the performance of young adults trained in maintaining balance while standing on a moving platform synchronized with a virtual reality road travel scene. The training protocol included eight 3 min long iterations of the road scene. Center of Pressure (CoP) displacements were analyzed for each task iteration within the training session, as well as during tests at 24h, 4 weeks and 12 weeks post-training to test for consolidation phase ("offline") gains and assess retention. In addition, CoP displacements in reaction to external perturbations were assessed before and after the training session and in the 3 subsequent post-training assessments (stability tests). There were significant reductions in CoP displacements as experience accumulated within session, with performance stabilizing by the end of the session. However, CoP displacements were further reduced at 24h post-training (delayed "offline" gains) and these gains were robustly retained. There was no transfer of the practice-related gains to performance in the stability tests. The time-course of learning the balance maintenance task, as well as the limitation on generalizing the gains to untrained conditions, are in line with the results of studies of manual movement skill learning. The current results support the conjecture that a similar repertoire of basic neuronal mechanisms of plasticity may underlay skill (procedural, "how to" knowledge) acquisition and skill memory consolidation in voluntary and balance maintenance tasks.

    Same session endosonography (EUS) immediately prior to scheduled endoscopic retrograde cholangiopancreatography (ERCP) may eliminate the need for ERCP and its associated risks in pregnant patients with no evidence of choledocholithiasis on EUS. In patients with choledocholithiasis, EUS provides information regarding the location, size and number of stones present, which helps guide biliary interventions and confirm stone clearance without the use of fluoroscopy. We retrospectively identified 10 pregnant patients referred to our tertiary endoscopy center for suspected choledocholithiasis between June 2008 and January 2012. All patients underwent same-session EUS-based ERCP. Of 10 pregnant patients managed with EUS-guided ERCP, six were found to have common bile duct stones and went on to ERCP. Four patients with no evidence of choledocholithiasis on EUS did not undergo ERCP. Patients with confirmed choledocholithiasis underwent ERCP without the use of fluoroscopy using the additional information provided by EUS. Same-session EUS immediately prior to scheduled ERCP may eliminate the need for ERCP and its risks in pregnant patients with no evidence of choledocholithiasis on EUS. In patients with confirmed choledocholithiasis, EUS provided additional information regarding the location, number and size of bile duct stones, which enabled the successful clearance of the bile duct without the use of fluoroscopy. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    2016-03-01

    Initial root canal treatment is highly successful, appreciated by patients, and cost-effective, but failures occur. Should a tooth with unsuccessful initial root canal treatment be treated by means of other endodontic procedures or be replaced by a single-tooth implant? Results from systematic reviews of the outcomes of nonsurgical retreatment, apical surgery, replantation, and autotransplantation show high tooth survival rates. Nonsurgical retreatment generally is prioritized before surgical endodontic treatment. Microsurgical endodontic treatment is superior to traditional surgical endodontic treatment and has high survival rates. Intentional replantation remains a viable alternative to extraction. Autotransplantation has a place, particularly in growing patients with an appropriate donor tooth. Single-tooth implants have higher survival rates, but the natural state has intrinsic value. The first-line treatment option after failure of initial root canal treatment is nonsurgical retreatment. Endodontic surgery, intentional replantation, and autotransplantation should be considered before extraction and replacement by a single-tooth implant. Comprehensive case assessment, evaluation of all endodontic options, and risk assessment for caries and periodontal disease are always necessary when choosing the optimal treatment for a patient when initial root canal treatment has failed to heal.

    In low-level laser therapy (LLLT), applications are generally performed in repetitive sessions using wavelengths of around 800 nm, at which the depth of penetration of laser is greater. The present study aimed to investigate the effects of LLLT with a 940 nm diode laser, which was performed extraorally on all the primarily and secondarily affected areas immediately after surgery in a single session, on pain, swelling, and trismus that occurred after impacted tooth extraction. Thirty-five outpatients with similarly impacted lower third molars on both sides were selected. The teeth of patients were removed in two separate operations. Postoperatively, the patients received laser therapy with energy of 4 J/cm(2) on one side and no laser energy was applied to the other side (placebo side). Swelling, trismus, and subjective assessment of pain on a visual analog scale were evaluated and compared between the laser-treated and placebo sides. There was no statistically significant difference in pain, swelling, or trismus between the sides (Mann-Whitney U test p > 0.05). However, according to the clinical outcomes, swelling and trismus were less in the laser-treated side than in the placebo side. A single-session LLLT that would be applied with a diode laser immediately after impacted tooth extraction might help patients to be less affected by postoperative trismus and swelling.

    To investigate surgical outcomes between retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) groups for a main stone sized 15 to 30 mm and located in the lower-pole calyx. Patients who underwent PNL or RIRS for a main stone sized 15 to 30 mm and located in the lower-pole calyx were retrospectively reviewed. Each patient in the RIRS group was matched to one in the PNL group on the basis of calculated propensity scores by use of age, sex, body mass index, previous treatment history, stone site, maximum stone size, and stone volume. We compared perioperative outcomes between the unmatched and matched groups. Patients underwent PNL (n=87, 66.4%) or RIRS (n=44, 33.6%). After matching, 44 patients in each group were included. Mean patient age was 54.4 ± 13.7 years. Perioperative hemoglobin drop was significantly higher and the hospital stay was longer in the PNL group than in the RIRS group. The operative time was significantly longer in the RIRS group than in the PNL group. Stone-free rates were higher and complications rates were lower in the RIRS group than in the PNL group without statistical significance. The presence of a stone located in the lower-anterior minor calyx was a predictor of stone-free status. RIRS and single-session PNL for patients with a main stone of 15 to 30 mm located in the lower-pole calyx showed comparable surgical results. However, RIRS can be performed more safely than PNL with less bleeding. Stones in the lower-anterior minor calyx should be carefully removed during these procedures.

    Root canal treatment (RoCT), or endodontic treatment, is a common procedure in dentistry. The main indications for RoCT are irreversible pulpitis and necrosis of the dental pulp caused by carious processes, tooth cracks or chips, or dental trauma. Successful RoCT is characterised by an absence of symptoms and clinical signs in teeth without radiographic evidence of periodontal involvement. The success of RoCT depends on a series of variables related to the preoperative condition of the tooth, as well as the endodontic procedures. To compare the effectiveness of single- and multiple-visit RoCT, measured as tooth extraction due to endodontic problems and radiological success.To assess the difference in short- and long-term complications between single- and multiple-visit RoCT. The following databases were searched for relevant trials: Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE, and EMBASE. Handsearching was performed for the major oral medicine journals. References of included studies and reviews were checked. Endodontics experts were contacted through e-mail. No language limitations were imposed. Date of last search was 6th March 2007. Randomised and quasi-randomised controlled trials of patients needing RoCT were included. Surgical endodontic treatment was excluded. The outcomes considered were the number of teeth extracted for endodontic problems; radiological success after at least 1 year, that is, absence of any periapical radiolucency; postoperative pain; painkiller use; swelling; or sinus track formation. Data were collected using a specific extraction form. The validity of included studies was assessed on the basis of allocation concealment, blindness of the study, and loss of participants. Data were analysed by calculating risk ratios. When valid and relevant data were collected, a meta-analysis of the data was undertaken. Twelve randomised controlled trials were included in the review. Four studies had a low risk of bias, four a moderate

    Currently, urban wastewaters (UWW) laden with organic carbon (BOD) and nutrients (ammoniacal nitrogen, N, and phosphates, P) are treated in multi-stage, energy-intensive process trains to meet the mandated discharge standards. This study presents a single-step process based on mixotrophic metabolism for simultaneous removal of carbon and nutrients from UWWs. The proposed system is designed specifically for hot, arid environments utilizing an acidophilic, thermotolerant algal species, Galdieria sulphuraria, and an enclosed photobioreactor to limit evaporation. Removal rates of BOD, N, and P recorded in this study (14.93, 7.23, and 1.38 mg L(-1) d(-1), respectively) are comparable to literature reports. These results confirm that the mixotrophic system can reduce the energy costs associated with oxygen supply in current UWW treatment systems, and has the potential to generate more energy-rich biomass for net energy extraction from UWW.

    The aim of the present study was to compare the effects of high-intensity interval training (HIIT) vs high-volume training (HVT) on salivary stress markers [cortisol (sC), testosterone (sT), alpha-amylase (sAA)], metabolic and cardiorespiratory response in young athletes. Twelve young male cyclists (14 ± 1 years; 57.9 ± 9.4 mL min -1  kg -1 peak oxygen uptake) performed one session of HIIT (4 × 4 min intervals at 90-95 % peak power output separated by 3 min of active rest) and one session of HVT (90 min constant load at 60 % peak power output). The levels of sC, sT, their ratio (sT/sC) and sAA were determined before and 0, 30, 60, 180 min after each intervention. Metabolic and cardiorespiratory stress was characterized by blood lactate, blood pH, respiratory exchange ratio (RER) and heart rate (HR), oxygen uptake ([Formula: see text]), ventilation (V E ) and ventilatory equivalent (V E /[Formula: see text]). sC increased 30 and 60 min after HIIT. However, 180 min post exercise, sC decreased below baseline levels in both conditions. sT increased 0 and 30 min after HIIT and 0 min after HVT. sAA and sT/sC ratio did not change significantly over time in HIIT nor HVT. Metabolic and cardiorespiratory stress, evidenced by blood lactate, HR, [Formula: see text], V E , and V E /[Formula: see text] was higher during HIIT compared to HVT. The metabolic and cardiorespiratory stress during HIIT was higher compared to HVT, but based on salivary analyses (cortisol, testosterone, alpha-amylase), we conclude no strong acute catabolic effects neither by HIIT nor by HVT.

    2015-08-01

    Full Text Available BackgroundTranscranial direct current stimulation (tDCS, a non-invasive method of brain stimulation, is an adjunctive research-therapy for aphasia. The concept supporting translational application of tDCS is that brain plasticity, facilitated by language intervention, can be enhanced by non-invasive brain stimulation. This study combined tDCS with an ecologically-focused behavioral approach that involved training nouns and verbs in sentences. MethodParticipant: A 43-year-old, right-handed male with fluent-anomic aphasia who sustained a single-left-hemisphere-temporal-parietal stroke was recruited. Treatment: Instrumentation included the Soterix Medical 1x1 Device. Anodal tDCS was applied over Broca’s area. Behavioral materials included: sentence production, naming in the sentence context, and implementation of a social-conversational-discourse treatment.Design and Procedures: The independent variable of this crossover case-study was tDCS, and the dependent variables were language and quality-of-life measures. In each session the subject received language treatment with the first twenty minutes additionally including tDCS. ResultsPerformance in naming nouns and verbs in single words and sentences were obtained. Verb production in the sentence context increased after active anodal tDCS and speech-language treatment. ConclusionAphasia treatment that involves naming in the sentence context in conjunction with translational application of tDCS may be a promising approach for language-recovery post stroke.

    Exercise has been demonstrated to enhance subsequent insulin-stimulated glucose uptake (GU) by predominantly type II (fast-twitch) muscle of old rats, but previous research has not evaluated exercise effects on GU by type I (slow-twitch) muscle from old rats. Accordingly, we studied male Fischer 344/Brown Norway rats (24 months old) and determined GU (0, 100, 200, and 5,000 μU/ml insulin) of isolated soleus (predominantly type I) and epitrochlearis (predominantly type II) muscles after one exercise session. Epitrochlearis (100, 200, and 5,000 μU/ml insulin) and soleus (100 and 200 μU/ml insulin) GU were greater at 3-h postexercise vs. age-matched sedentary controls. Insulin receptor tyrosine phosphorylation (Tyr1162/1163) was unaltered by exercise in either muscle. Akt phosphorylation (pAkt) was greater for exercised vs. sedentary rats in the epitrochlearis (Ser473 and Thr308 with 100 and 200 μU/ml, respectively) and soleus (Ser473 with 200 μU/ml). AS160 phosphorylation (pAS160) was greater for exercised vs. sedentary rats in the epitrochlearis (Thr642 with 100 μU/ml), but not the soleus. Exercised vs. sedentary rats did not differ for total protein abundance of insulin receptor, Akt, AS160, or GLUT4 in either muscle. These results demonstrate that both predominantly type I and type II muscles from old rats are susceptible to exercise-induced improvement in insulin-mediated GU by mechanisms that are independent of enhanced insulin receptor tyrosine phosphorylation or altered abundance of important signaling proteins or GLUT4. Exercise-induced elevation in pAkt, and possibly pAS160, may contribute to this effect in the epitrochlearis of old rats, but other mechanisms are likely important for the soleus.

    Full Text Available Symptoms of visuospatial neglect occur frequently after unilateral brain damage. Neglect hampers rehabilitation progress and is associated with reduced quality of life. However, existing treatment methods show limited efficacy. Transcranial direct current stimulation (tDCS is a neuromodulatory technique, which can be used to increase or decrease brain excitability. Its combination with conventional neglect therapy may enhance treatment efficacy.A 72-year-old male with a subacute ischaemic stroke of the right posterior cerebral artery suffering from visuospatial neglect, hemianopia, and hemiparesis was treated with biparietal tDCS and cognitive neglect therapy in a double-blind, sham-controlled single-case study. Four weeks of daily treatment sessions (5 days per week, 30 min were started 26 days post-stroke. During week 1 and 4 the patient received conventional neglect therapy, during week 2, conventional neglect therapy was combined once with sham and once with real biparietal tDCS. Week 3 consisted of daily sessions of real biparietal tDCS (1 mA, 20 min combined with neglect therapy. Outcome measures were assessed before, immediately after, as well as 1 week and 3 months after the end of treatment. They included subtests of the Test for Attentional Performance (TAP: covert attention (main outcome, alertness, visual field; the Neglect-Test (NET: line bisection, cancellation, copying; and activities of daily living (ADL. After real stimulation, covert attention allocation towards left-sided invalid stimuli was significantly improved, and line bisection and copying improved qualitatively as compared to sham stimulation. ADL were only improved at the 3-month follow-up. This single-case study demonstrates for the first time that combined application of tDCS and cognitive training may enhance training-induced improvements in measures of visuospatial neglect and is applicable in a clinical context.

    to compare the outcomes of a regenerative strategy based on recombinant human platelet-derived growth factor-BB (rhPDGF-BB, 0.3 mg/ml) and β-tricalcium phosphate (β-TCP) in the treatment of intraosseous defects accessed with the Single Flap Approach (SFA) versus Double Flap Approach based on papilla preservation techniques (DFA). Fifteen and 13 defects, randomly assigned to SFA or DFA, respectively, were grafted with rhPDGF-BB + β-TCP. Probing parameters were assessed before and 6 months after surgery. Pain (VAS(pain)) was self-reported using a visual analogue scale. Twelve SFA sites and DFA 6 sites showed complete flap closure at 2 weeks post-surgery. No significant differences in 6-month changes in probing parameters and radiographic defect fill were found between groups. Significantly lower VAS(pain) was observed in SFA group compared to DFA group at day +1, +2 and +6. A significantly greater number of analgesics were consumed in the DFA group compared to the SFA group at day +1. When combined with rhPDGF-BB and β-TCP, the SFA may result in similar clinical outcomes, better quality of early wound healing, and lower pain and consumption of analgesics during the first postoperative days compared to the DFA. © 2015 John Wiley & Sons A/S.

  20. Arterial hypertension: second-line treatment. Try other single-agent treatments.

    2008-06-01

    (1) Reliable evidence supports the use of thiazide diuretics (chlortalidone or hydrochlorothiazide) as first-line treatment for uncomplicated arterial hypertension. (2) When patients fail to reach blood pressure targets with well-conducted treatment with thiazide diuretics, or this treatment is poorly tolerated, what are the best second-line options? To answer this question, we reviewed the available evidence, based on our standard in-house methodology. (3) We found no published trials specifically designed to evaluate second-line antihypertensive treatments in cardiovascular prevention. There were no available trials of dual- versus single-agent therapy after failure of a thiazide diuretic. (4) When the blood pressure target is not reached, inadequate drug efficacy is only one of several possible causes. Various other factors affecting blood pressure should also be investigated. (5) Dual-agent therapy carries an increased risk of adverse effects and drug interactions compared to monotherapy. (6) There is no consensus among clinical practice guidelines on second-line antihypertensive therapy. However, to minimise the risk of adverse effects, it is clearly better to select single-agent therapy with a drug that has been shown to prevent cardiovascular events in first-line treatment of otherwise healthy hypertensive patients. Possible options include: angiotensin-converting-enzyme inhibitors, angiotensin II antagonists, calcium channel blockers or betablockers. In patients over the age of 60, betablockers seem less effective that the other drugs in preventing strokes. (7) There is too little evidence to choose a specific third-line combination rather than another. However, any adverse effects that the patient experienced during prior treatments should be taken into account.

    Full Text Available In this study, researchers evaluate a homework exercise assigned before a standalone information literacy session. Students in a Master of Education program completed a worksheet using the ERIC database thesaurus. The researchers conducted pre- and posttests within a single library session to assess student learning, using a control group for comparison. The treatment group did not demonstrate better thesaurus skills than students who had regular library instruction alone, but results pointed the way to targeted improvements of pre-session learning materials. This approach could inform other information literacy homework applications such as flipping the classroom.

Six male youth basketball players (age, 16.5±0.5 years; height, 195.5±6.75 cm; body mass, 93.9±10.9 kg; and body mass index, 23.6±2.8 kg.m-2 were monitored (HR, type and duration of workouts during 15 (66 individual training sessions (80±26 minutes. Edwards’ HR method was used as a reference measure of internal training load (ITL; the CR-10 RPE scale was administered 30 minutes after the end of each session. The results obtained showed that all comparisons between different session durations and workout portions revealed effects in term of Edwards’ ITLs except for warm-up portions. Moderate to strong relationships between Edwards’ and session- RPE methods emerged for all sessions (r = .85, P < .001, player’s sessions (r range = .79 - .95, P < .001, session durations (< 80 minutes: r = .67, P < .001; ≥ 80 minutes: r = .75, P < .001, and workout portions (r range = .78 - .89, P range = .002 - < .001. The findings indicated that coaches of youth basketball players can successfully use session-RPE to monitor the ITL, regardless of session durations and workout portions.

    To evaluate a comprehensive magnetic resonance imaging (MRI) protocol as noninvasive diagnostic modality for simultaneous detection of parenchymal, biliary, and vascular complications after liver transplantation. Fifty-two liver transplant recipients suspected to have parenchymal, biliary, and (or) vascular complications underwent our MRI protocol at 1.5T unit using a phased array coil. After preliminary acquisition of axial T 1 w and T 2 w sequences, magnetic resonance cholangiography (MRC) was performed through a breath-hold, thin- and thick-slab, single-shot T 2 w sequence in the coronal plane. Contrast-enhanced magnetic resonance angiography (CEMRA) was obtained using a 3-dimensional coronal spoiled gradient-echo sequence, which enabled acquisition of 32 partitions 2.0 mm thick. A fixed dose of 20 ml gadobenate dimeglumine was administered at 2 mL/s. A post-contrast T 1 w sequence was also performed. Two observers in conference reviewed source images and 3-dimensional reconstructions to determine the presence of parenchymal, biliary, and vascular complications. MRI findings were correlated with surgery, endoscopic retrograde cholangiography (ERC), biopsy, digital subtraction angiography (DSA), and imaging follow-up. MRI revealed abnormal findings in 32 out of 52 patients (61%), including biliary complications (anastomotic and nonanastomotic strictures, and lithiasis) in 31, vascular disease (hepatic artery stenosis and thrombosis) in 9, and evidence of hepatic abscess and hematoma in 2. ERC confirmed findings of MRC in 30 cases, but suggested disease underestimation in 2. DSA confirmed 7 magnetic resonance angiogram (MRA) findings, but suggested disease overestimation in 2. MRI combined with MRC and CEMRA can provide a comprehensive assessment of parenchymal, biliary, and vascular complications in most recipients of liver transplantation. (author)

    The objective of this work was to determine the dynamics of maximal anaerobic power (MAP) of the lower limbs, following a single whole body cryostimulation treatment (WBC), in relation to the temperature of thigh muscles. The subjects included 15 men and 15 women with an average age (± SD) of 21.6 ± 1.2 years. To evaluate the level of anaerobic power, the Wingate test was applied. The subjects were submitted to 6 WBC treatments at -130°C once a day. After each session they performed a single Wingate test in the 15, 30, 45, 60, 75 and 90th min after leaving the cryogenic chamber. The order of the test was randomized. All Wingate tests were preceded by an evaluation of thigh surface temperature with the use of a thermovisual camera. The average thigh surface temperature (T(av)) in both men and women dropped significantly after the whole body cryostimulation treatment, and next increased gradually. In women T(av) remained decreased for 75 min, whereas in men it did not return to the basal level until 90th min. A statistically insignificant decrease in MAP was observed in women after WBC. On the contrary, a non-significant increase in MAP was observed in men. The course of changes in MAP following the treatment was similar in both sexes to the changes in thigh surface temperature, with the exception of the period between 15th and 30th min. The shorter time to obtain MAP was observed in women till 90th min and in men till 45 min after WBC compared to the initial level. A single whole body cryostimulation may have a minor influence on short-term physical performance of supramaximal intensity, but it leads to improvement of velocity during the start as evidenced by shorter time required to obtain MAP.

    Full Text Available The development of the SJ Framework for session-based distributed programming is part of recent and ongoing research into integrating session types and practical, real-world programming languages. SJ programs featuring session types (protocols are statically checked by the SJ compiler to verify the key property of communication safety, meaning that parties engaged in a session only communicate messages, including higher-order communications via session delegation, that are compatible with the message types expected by the recipient. This paper presents current work on security aspects of the SJ Framework. Firstly, we discuss our implementation experience from improving the SJ Runtime platform with security measures to protect and augment communication safety at runtime. We implement a transport component for secure session execution that uses a modified TLS connection with authentication based on the Secure Remote Password (SRP protocol. The key technical point is the delicate treatment of secure session delegation to counter a previous vulnerability. We find that the modular design of the SJ Runtime, based on the notion of an Abstract Transport for session communication, supports rapid extension to utilise additional transports whilst separating this concern from the application-level session programming task. In the second part of this abstract, we formally prove the target security properties by modelling the extended SJ delegation protocols in the pi-calculus.

The first topic, QCD Exclusive Reactions and Color Transparency, featured talks by Ralston, Heppelman and Strikman; the second, QCD and Inclusive Reactions had talks by Garvey, Speth and Kisslinger. The third dynamics session, Medium Modification of Elementary Interactions had contributions from Kopeliovich, Alves and Gyulassy; the fourth session Pre-QCD Dynamics and Scattering, had talks by Harris, Myhrer and Brown. An additional joint Spectroscopy/Dynamics session featured talks by Zumbro, Johnson and McClelland. These contributions are reviewed briefly in this summary.

    The erbium:yttrium-aluminium-garnet (Er:YAG) laser has recently been used in the fractional resurfacing of photo-aged skin. Our study evaluated the results after one single session of fractional resurfacing with Er:YAG. Thirty women participated in the study, with an average age of 46 years, skin types from II to IV, and wrinkle grades I to III. The 2,940 nm Er:YAG system used (Pixel, Alma Laser, Israel) had variable pulse durations (1 ms to 2 ms) and energy densities (800 mJ/cm(2) to 1,400 mJ/cm(2)) which, together with the number of passes (four to eight), were selected as a function of wrinkle severity. All patients received only one treatment. Postoperative side effects were evaluated. The number of wrinkles was documented with clinical photography and was scored. Histological assessment was carried out on two patients before and 2 months after treatment. All patients completed the study. Of the patients, 93% reported good or very good improvement of the degree of their wrinkles, with a satisfaction index of 83%. Pain was not a problem during treatment, and there were no side effects except for in one phototype IV patient, who had hyperpigmentation. Histology 2 months after the single treatment demonstrated younger morphology of both the epidermis and dermis, with improvement of the pretreatment typical elastotic appearance. At the parameters used in our study, only one treatment session of Er:YAG laser could achieve effective skin rejuvenation, with effects recognized in both the dermis and, more importantly, the epidermis. This regimen offers an interesting alternative to the conventional approach of multi-session fractional resurfacing.

    Topical corticosteroid or corticosteroid/calcipotriol preparations are recommended first-line topical treatments of psoriasis, but a main cause for the lack of efficacy of topical treatments is considered low rates of adherence to topical drugs. Patient support by the use of applications (apps) for smartphones is suggested to improve medical adherence. Design: An investigator-initiated, single-center, single-blind, parallel-group, phase-4 clinical superiority randomized controlled trial (RCT). 134 patients 18 to 75 years of age with mild-to-moderate psoriasis, who are capable of reading English language, own a smartphone, and are candidates for the study drug calcipotriol and betamethasone dipropionate (Cal/BD) cutaneous foam once daily prn (pro re nata). A 28-day adherence-supporting app providing compulsory daily treatment reminders that pop-up on the smartphone screen with a short alert sound. The app synchronizes through Bluetooth® to an electronic monitor (EM) attached to the medication canister. The EM contains a chip registering the amount of foam, day and time the patient use the foam dispenser. The information is displayed in a diary that shows the amount of Cal/BD cutaneous foam used and the number of applied treatment sessions. The app has an optional diary with the patient's rating of symptoms. Non-intervention: Use of Cal/BD cutaneous foam and EM without the app. All participants are prescribed Cal/BD cutaneous foam prn for the entire study period. Primary outcome obtained in week 4: rates of adherence measured by patient report, weight of medication canisters, and number of treatment sessions measured by the EM. Secondary outcomes obtained at baseline, weeks 4, 8, and 26: Lattice System Physician's Global Assessment (LS-PGA) and Dermatology Quality of Life Index (DLQI). This trial tests of whether an app can improve rates of adherence to a topical antipsoriatic drug. If the app improves rates of adherence and reduces the burden of psoriasis in a

    Objectives This retrospective study describes the use of acupuncture for adult sickle cell patients in a single institution. Methods We identified 47 sickle cell disease (SCD) patients referred for acupuncture at the National Institutes of Health between January, 2005 and September, 2011. All patients were enrolled in a Study of the Natural History of SCD and signed consent. We reviewed patient demographics, location of acupuncture treatment sessions (inpatient versus outpatient), number of sessions received, sites of pain, patient pain reporting, and the use of other complementary therapies. Results Of the 47 patients (60% women, median age 36 years) referred for acupuncture, 42 had homozygous SS disease (89%) and 5 had SC disease (11%). Over half of the patients (51%) reported more than 3 sites of pain. Only 24 patients (51%) underwent acupuncture treatment. Of those who elected not to receive acupuncture, a majority (87%) accepted some other forms of complementary therapies. Nine patients underwent only inpatient acupuncture for acute vaso-occlusive crisis (VOC). Eleven patients received only outpatient acupuncture treatment for chronic pain, and four patients received both inpatient and outpatient treatments. For the patients who received inpatient acupuncture treatment for acute VOC, there was a significant reduction of reported pain score immediately after acupuncture treatment with an average pain reduction of 2.1 points on the numeric pain scale (ppain as improved compared to prior session. Discussion To our knowledge, this is the largest retrospective review of acupuncture use in the sickle cell population. This analysis describes the use of acupuncture and raises the possibility of its use as an adjuvant for pain management in this population. Future clinical trials are needed to evaluate acupuncture’s efficacy and effectiveness for pain management in different treatment settings and for various types of pain etiologies among the sickle cell population

    2009-02-01

    Lichens are reputedly slow growing and become unhealthy or die in response to supplements of the usual limiting resources, such as water and nitrogen. We found, however, that the tripartite cyanobacterial lichen Lobaria pulmonaria doubled in annual biomass growth after a single 20-minute immersion in a phosphorus solution (K2HPO4), as compared to controls receiving no supplemental phosphorus. This stimulation of cyanolichens by phosphorus has direct relevance to community and population ecology of lichens, including improving models of lichen performance in relation to air quality, improving forest management practices affecting old-growth associated cyanolichens, and understanding the distribution and abundance of cyanolichens on the landscape. Phosphorus may be as important a stimulant to cyanobacterial-rich lichen communities as it is to cyanobacteria in aquatic ecosystems.

    The evidence base for the treatment of morbid jealousy with integrative therapies is thin. This study explored the efficacy of cognitive analytic therapy (CAT). An adjudicated hermeneutic single-case efficacy design evaluated the cognitive analytic treatment of a patient meeting diagnostic criteria for obsessive morbid jealousy. A rich case record was developed using a matrix of nomothetic and ideographic quantitative and qualitative outcomes. This record was then debated by sceptic and affirmative research teams. Experienced psychotherapy researchers acted as judges, assessed the original case record, and heard the affirmative-versus-sceptic debate. Judges pronounced an opinion regarding the efficacy of the therapy. The efficacy of CAT was supported by all three judges. Each ruled that change had occurred due to the action of the therapy, beyond any level of reasonable doubt. This research demonstrates the potential usefulness of CAT in treating morbid jealousy and suggests that CAT is conceptually well suited. Suggestions for future clinical and research directions are provided. The relational approach of CAT makes it a suitable therapy for morbid jealousy. The narrative reformulation component of CAT appears to facilitate early change in chronic jealousy patterns. It is helpful for therapists during sessions to use CAT theory to diagrammatically spell out the patterns maintaining jealousy. © 2017 The British Psychological Society.

  10. A comparative study of single-dose treatment of chancroid using thiamphenicol versus Azithromycin

    Directory of Open Access Journals (Sweden)

    Walter B. Junior

    Full Text Available A study was conducted in São Paulo, Brazil, to compare azithromycin with thiamphenicol for the single-dose treatment of chancroid. In all, 54 men with chancroid were tested. The etiology was determined by clinical characterization and direct bacterioscopy with Gram staining. None of the patients had positive serology or dark-field examination indicating active infection with Treponema pallidum. Genital infections due to Neisseria gonorrhoeae and herpes simplex virus were excluded by polymerase chain reaction testing. For 54 patients with chancroid, cure rates with single-dose treatment were 73% with azithromycin and 89% with thiamphenicol. HIV seropositivity was found to be associated with treatment failure (p=0.001. The treatment failed in all HIV positive patients treated with azithromycin (p=0.002 and this drug should be avoided in these co-infected patients. In the view of the authors, thiamphenicol is the most indicated single-dose regimen for chancroid treatment.

    Therapeutic methods that inhibit microbial ingress into filled root canals are desirable. This in vivo study assessed the inhibition of periapical inflammation subsequent to coronal inoculation in canals medicated with 2% chlorhexidine gel and filled with Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT). Six Beagle dogs each had 10 two-rooted premolars treated. In group 1 (n = 36 roots), 1 root/tooth had the canal conditioned with Primer Epiphany, filled with Epiphany sealer and Resilon core in 1 session, and coronally sealed with PhotacFil. In group 2 (n = 36 roots), the second root/tooth had the canal medicated with 2% chlorhexidine gel for 1 week and then filled and coronally sealed as in group 1. After 3 weeks, canals were exposed to the oral environment for 7 days, inoculated with isologous plaque, and coronally sealed. Negative controls treated as groups 1 and 2 remained sealed. Positive controls had canals unfilled and exposed. Seven months after inoculation, dogs were euthanized; jaw blocks processed for histologic examination; and periapical inflammation (PI) recorded as none, mild, or severe. In groups 1 and 2, severe PI occurred in 5 of 65 roots (8%) and mild PI in 18 of 65 roots (28%) with a significantly higher (P = .031) PI incidence in group 2 than in group 1. Negative controls had only mild PI in 9 of 29 roots (31%). Roots medicated with 2% chlorhexidine gel had mild PI significantly more (P = .009) than roots filled in 1 session (more than 2-fold). Intracanal medication with 2% chlorhexidine gel and root filling with Resilon/Epiphany did not effectively inhibit apical periodontitis subsequent to coronal inoculation.

    Full Text Available It has been demonstrated that exposure to a variety of stressful experiences enhances fearful reactions when behavior is tested in current animal models of anxiety. Until now, no study has examined the neurochemical changes during the test and retest sessions of rats submitted to the elevated plus maze (EPM. The present study uses a new approach (HPLC by looking at the changes in dopamine and serotonin levels in the prefrontal cortex, amygdala, dorsal hippocampus, and nucleus accumbens in animals upon single or double exposure to the EPM (one-trial tolerance. The study involved two experiments: i saline or midazolam (0.5 mg/kg before the first trial, and ii saline or midazolam before the second trial. For the biochemical analysis a control group injected with saline and not tested in the EPM was included. Stressful stimuli in the EPM were able to elicit one-trial tolerance to midazolam on re-exposure (61.01%. Significant decreases in serotonin contents occurred in the prefrontal cortex (38.74%, amygdala (78.96%, dorsal hippocampus (70.33%, and nucleus accumbens (73.58% of the animals tested in the EPM (P < 0.05 in all cases in relation to controls not exposed to the EPM. A significant decrease in dopamine content was also observed in the amygdala (54.74%, P < 0.05. These changes were maintained across trials. There was no change in the turnover rates of these monoamines. We suggest that exposure to the EPM causes reduced monoaminergic neurotransmission activity in limbic structures, which appears to underlie the "one-trial tolerance" phenomenon.

    2011-01-01

    The purpose of this study was to clarify the efficacy of radioiodine (RI) therapy in Japanese patients with autonomously functioning thyroid nodules (AFTNs). We performed a retrospective analysis to assess the management of AFTN patients. Thyroid lobectomy was performed to treat toxic adenoma (TA) patients, and total thyroidectomy to treat toxic multinodular goiter (TMNG) patients. RI therapy was administered in the form of a single dose (500 MBq) of isotope in the outpatient clinic. Percutaneous ethanol injection therapy (PEIT) was performed under ultrasound guidance. Of the total 205 patients, consisting of 159 TA and 46 TMNG patients, 99 underwent surgery, 50 received RI therapy, and 56 received PEIT. Remission of thyrotoxicosis was achieved in all of the patients who were treated surgically. Hypothyroidism was documented in six of the 72 patients who were treated surgically other than by total thyroidectomy. Remission of thyrotoxicosis was observed in 43 of the 50 patients who were treated by RI therapy. Nine TA patients developed hypothyroidism during the follow-up period after RI therapy. Several PEIT sessions were required to achieve a remission of thyrotoxicosis. Remission of thyrotoxicosis was achieved in 29 of the 56 patients treated by PEIT, and thyrotoxicosis recurred in 17 these 56 patients. Surgery is the treatment of choice for large nodules and nodules that are resistant to other treatments, because it allows prompt control of thyrotoxicosis. RI therapy is a safe and effective means of controlling thyrotoxicosis in AFTN patients. We conclude that RI therapy is the treatment of choice for definitive treatment of AFTN patients who do not have local compression symptoms. (author)

    To determine the frequency of flare-ups in single-visit endodontic treatment and the associated factors. Observational. Baqai Dental College Hospital, Karachi, from November 2005 to May 2006. One hundred patients were assigned for single-visit root canal treatment. Patients that defaulted after the first appointment (incomplete treatment) were excluded from the study. For each tooth treated, the clinical factors and conditions existing before and after the completion of treatment were recorded. This data included patient's age, gender, type of tooth, pre-operative status of pulp and periapical tissues and recording pain and swelling (flare-ups) postoperatively after 1 day, 7 days and 1 month. The significance of results was obtained by applying paired-sample t-test and Pearson X2 test. Three of one hundred cases showed flare-ups after treated in single appointment. On the other hand, a marked number (n=97) of cases did not show flare-ups during the study period. None of the studied variables showed any statistically significant bearing on rate of flare-ups in single appointment root canal treatment. The single-visit root canal treatment was safe in terms of endodontic flare-ups as far as results of this study are concerned. It was safer in both vital and non-vital teeth, and even in teeth with periapical pathosis.

    Snoring is usually caused by the vibration of walls of the soft palate at the pharyngeal level. Its worldwide prevalence is estimated to range between 2 and 85% depending on age, gender or population group. The aim of this study is to determine the degree of improvement that can be subjectively evident in patients treated by snoring with radiofrequency-assisted uvulopalatoplasty based on a one-session protocol. This is a prospective, longitudinal, non-randomized study. Patients of both sexes, aged 18 years, who attended to the ENT consultation in a tertiary hospital with snoring during the period of July 2012-July 2013 were included. Age, body mass index, Epworth sleepiness scale were calculated. The volume of snoring of each subject was assessed using a visual analog scale. A total of 27 patients were included in the study; the average age of the sample was 49 years (±8.7; min 36/max 74); of these 22 (81.5%) were male and 5 (18.5%) females. The average BMI was 27.07 ± 2.5 (min 23.15/max 29.39) before the test and after 1 year was 26.75 ± 2.32 (min 23.11/max 29.56) with no statistically significant differences in BMI before and after surgery (p = 0.407). Preoperative snoring intensity was 8.10 ± 0.93 according to VAS. We found a statistically significant difference in the post-operative intensity at 3 months of 3.93 ± 0.88 (p ≤ 0.05) at 6 months of 4.41 ± 1.08 (p ≤ 0.05), and after 1 year 4.90 ± 0.77 (p ≤ 0.05). The average rate of ESS was significantly higher preoperatively than post-operative, being 8.76 ± 3.1 preoperative and 6.93 ± 1.68 post-operative (p ≤ 0.05). We conclude that the use of radiofrequency in simple snorers with an apnea/hypopnea index snoring is the soft palate, can be treated by one-session protocol, being possible to obtain an improvement of snoring up to 70% of cases by a short follow-up period.

    We evaluated an autoradiographic (ARG) method to calculate regional cerebral blood flow (rCBF) sequentially before and after an acetazolamide (ACZ) challenge in a single session of single-photon emission tomography (SPET) with two injections of N-isopropyl-[ 123 I]p-iodoamphetamine (IMP). The method uses a table look-up method with a fixed distribution volume (Vd) and a standard input function of IMP. To calculate rCBF after an ACZ challenge, two look-up tables (a dual-table) are used to reflect the effect of radioactivity in the brain from the first dose of IMP. We performed simulation studies to evaluate errors attributable to (a) a change in rCBF induced by an ACZ challenge during the scan and (b) a fixed Vd value that might be different from an individual one, along with the effect of (c) scan length. Thirty-three patients were studied by dynamic SPET with two injections of IMP and frequent arterial blood sampling, and the data were analysed using the dual-table ARG method. Twenty-four of the 33 patients received an injection of ACZ 10 min before the second dose of IMP. We generated a standard input function by averaging individual input functions. The optimal method to calibrate a standard input function was determined so that the SD of differences between rCBF calculated by using a calibrated standard input function (F SIF ) and that calculated by using an individual input function (F IIF ) was minimised. Reliability of the method was evaluated by comparing F SIF with gold standard rCBF (F REF ) obtained by two-compartment model analysis of dynamic SPET data and an individual input function with a non-linear least squares fitting method. Errors caused by (a) were less than 4% for a first rCBF ranging between 20 and 60 ml 100 g -1 min -1 and an rCBF change of between -25% and 50%. Errors caused by (b) were relatively large compared with those caused by (a), and were affected by (c) with an increasing error in a longer scan. In the patient study with a proposed

    Pascual-Leone and Greenberg's sequential model of emotional processing has been used to explore process in over 24 studies. This line of research shows emotional processing in good psychotherapy often follows a sequential order, supporting a saw-toothed pattern of change within individual sessions (progressing "2-steps-forward, 1-step-back"). However, one cannot assume that local in-session patterns are scalable across an entire course of therapy. Thus, the primary objective of this exploratory study was to consider how the sequential patterns identified by Pascual-Leone, may apply across entire courses of treatment. Intensive emotion coding in two separate single-case designs were submitted for quantitative analyses of longitudinal patterns. Comprehensive coding in these cases involved recording observations for every emotional event in an entire course of treatment (using the Classification of Affective-Meaning States), which were then treated as a 9-point ordinal scale. Applying multilevel modeling to each of the two cases showed significant patterns of change over a large number of sessions, and those patterns were either nested at the within-session level or observed at the broader session-by-session level of change. Examining successful treatment cases showed several theoretically coherent kinds of temporal patterns, although not always in the same case. Clinical or methodological significance of this article: This is the first paper to demonstrate systematic temporal patterns of emotion over the course of an entire treatment. (1) The study offers a proof of concept that longitudinal patterns in the micro-processes of emotion can be objectively derived and quantified. (2) It also shows that patterns in emotion may be identified on the within-session level, as well as the session-by-session level of analysis. (3) Finally, observed processes over time support the ordered pattern of emotional states hypothesized in Pascual-Leone and Greenberg's ( 2007 ) model of

    Full Text Available Prior work has extended the deep, logical connection between the linear sequent calculus and session-typed message-passing concurrent computation with equi-recursive types and a natural notion of subtyping. In this paper, we extend this further by intersection and union types in order to express multiple behavioral properties of processes in a single type. We prove session fidelity and absence of deadlock and illustrate the expressive power of our system with some simple examples. We observe that we can represent internal and external choice by intersection and union, respectively, which was previously suggested by Padovani for a different language of session types motivated by operational rather than logical concerns.

    The aim of this study was to study and analyze the factors influencing the treatment response to Q-switched alexandrite laser in patients with nevus of Ota and the factors influencing the number of laser sessions. Forty-eight patients treated with Q-switched alexandrite between 2009 and 2013 for nevus of Ota were enrolled in this retrospective, single-center study. The subjects (13 male, 35 female) were divided into three groups according to the number of treatment sessions. Patients were then called back to the hospital for a follow-up interview and examination. Single and multiple variate analyses of various factors were performed. The 48 patients were predominantly female (35 female, 13 male, F:M ratio = 2.7:1), mean age 17.2±10.41. Twenty-five (52.1%) had lesion on the right side of the face, 22 (45.8%) on the left side, and one (2.1%) on both sides. The predominant color was brown (41.7%), followed by cyan (39.6%) and lividity (18.8%). Satisfactory result was observed in all patients, after 3 to 11 treatment sessions (mean 5.37±2); 19 of these (39.6%) needed three to four sessions (short treatment sessions), 22 (45.8%) needed five to seven sessions (intermediate treatment sessions), and 7 (14.6%) needed nine to eleven sessions (long treatment sessions). The clinical response and treatment sessions of the young-age group were significantly better than the adult group. Those with higher Tanino's classification needed more treatment sessions. Dark-colored lesions, which reflect deep melanosis of the lesion, needed more sessions than lighter-colored lesions. As for skin color, better response was obtained in light-skinned patients than in dark-skinned ones. Two patients showed transient hypopigmentation that lasted for less than six months, and recurrence has been seen in one child with dark-colored lesion. Q-switched alexandrite laser is an ideal minimally-invasive method for treating nevus of Ota. Fewer treatment sessions are needed for children and younger

    Full Text Available Abstract Background In an event of a smallpox outbreak in humans, the window for efficacious treatment by vaccination with vaccinia viruses (VACV is believed to be limited to the first few days post-exposure (p.e.. We recently demonstrated in a mouse model for human smallpox, that active immunization 2–3 days p.e. with either VACV-Lister or modified VACV Ankara (MVA vaccines, can rescue animals from lethal challenge of ectromelia virus (ECTV, the causative agent of mousepox. The present study was carried out in order to determine whether a single dose of the anti-viral cidofovir (CDV, administered at different times and doses p.e. either alone or in conjunction with active vaccination, can rescue ECTV infected mice. Methods Animals were infected intranasally with ECTV, treated on different days with various single CDV doses and monitored for morbidity, mortality and humoral response. In addition, in order to determine the influence of CDV on the immune response following vaccination, both the "clinical take”, IFN-gamma and IgG Ab levels in the serum were evaluated as well as the ability of the mice to withstand a lethal challenge of ECTV. Finally the efficacy of a combined treatment regime of CDV and vaccination p.e. was determined. Results A single p.e. CDV treatment is sufficient for protection depending on the initiation time and dose (2.5 – 100 mg/kg of treatment. Solid protection was achieved by a low dose (5 mg/kg CDV treatment even if given at day 6 p.e., approximately 4 days before death of the control infected untreated mice (mean time to death (MTTD 10.2. At the same time point complete protection was achieved by single treatment with higher doses of CDV (25 or 100 mg/kg. Irrespective of treatment dose, all surviving animals developed a protective immune response even when the CDV treatment was initiated one day p.e.. After seven days post treatment with the highest dose (100 mg/kg, virus was still detected in some

    In this research, we have studied the consequences of three consecutive osteopathic manipulative sessions (OMS) on postural control by using a single-case research (SCR) design. The patient was a 77 years old woman complaining of altered balance and low-back pain. OMS were delivered by a single practitioner. The pain level was self-rated by using a visual Borg scale. The posture was monitored on a force platform. Postural parameters were deduced from the analysis of the centre of foot pressure (CoP) displacement. The statistical significance of the observed differences was established by using an SCR-related effect size indicator (i.e. Taunovlap). Our results indicate that OMS decrease the patient's pain, modify CoP mean position and decreased the length and velocity of the CoP displacement. Furthermore, modifications of the body oscillations were observed after OMS. This work indicates that OMS can improve body balance and that SCR allows the objective evaluation of the consequences of OMS. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available PURPOSE: To compare the efficacy and safety of the electromagnetic lithotripter in the treatment of pediatric lithiasis to that of the earlier electrohydraulic model. MATERIALS AND METHODS: Two groups of children with lithiasis aged between 10 and 180 months who underwent extracorporeal shock wave lithotripsy (ESWL. In the first group (26 children, ESWL was performed by using the electrohydraulic MPL 9000X Dornier lithotripter between 1994 and 2003 while in the second group (19 children the electromagnetic EMSE 220 F-XP Dornier lithotripter was used from April 2003 to May 2006. RESULTS: In the first group, 21/26 children (80.7% were stone free at first ESWL session. Colic pain resolved by administration of an oral analgesic in 6 (23%, brief hematuria (< 24 h resolved with increased fluid intake in 5 (19.2%, while slightly elevated body temperature (< 38°C occurred in 4 (15.3%. Four children (15.3% failed to respond to treatment and were treated with ureteroscopy. In the second group 18/19 children were completely stone free at first ESWL session (94.7%. Complications were infrequent and of minor importance: colic pain treated with oral analgesic occurred in 1 (5.26%, brief hematuria (< 24 h, resolved with increased fluid intake in 4 (21% and slightly elevated body temperature (< 38°C monitored for 48 hours occurred in 6 (31.5%. Statistical analysis showed that electromagnetic lithotripter is more efficacious and safer than the earlier electrohydraulic model. CONCLUSIONS: Technological development not only has increased efficacy and safety of lithotripter devices in treating pediatric lithiasis, but it also provided less painful lithotripsy by eliminating the need for general anesthesia.

    In health care systems, users may access multiple applications during one session of interaction with the system. However, users must sign on to each application individually, and it is difficult to maintain a common context among these applications. We are developing a session management system for web-based applications using LDAP directory service, which will allow single sign-on to multiple web-based applications, and maintain a common context among those applications for the user. This paper discusses the motivations for building this system, the system architecture, and the challenges of our approach, such as the session objects management for the user, and session security.

    Introduction A number of studies have established that children, adolescents and adults with Asperger syndrome (AS) and high functioning autism (HFA) have significant problems with anxiety. Cognitive behavioural therapy (CBT) is an effective treatment for anxiety in a variety of clinical populations. There is a growing interest in exploring the effectiveness of CBT for people with AS who have mental health problems, but currently there are no known clinical trials involving adults with AS or HFA. Studies with children who have AS have reported some success. The current study aims to examine whether modified group CBT for clinically significant anxiety in an AS population is likely to be efficacious. Methods and analysis This study is a randomised, single-blind crossover trial. At least 36 individuals will be recruited and randomised into a treatment arm or a waiting-list control arm. During treatment, individuals will receive 3 sessions of individual CBT, followed by 21 sessions of group CBT. Primary outcome measures focus on anxiety. Secondary outcome measures focus on everyday social and psychiatric functioning, additional measures of anxiety and fear, depression, health-related quality of life and treatment cost. Assessments will be administered at pregroup and postgroup and at follow-up by researchers who are blinded to group allocation. The trial aims to find out whether or not psychological treatments for anxiety can be adapted and used to successfully treat the anxiety experienced by people with AS. Furthermore, we aim to determine whether this intervention represents good value for money. Ethics and dissemination The trial received a favourable ethical opinion from a National Health Service (NHS) Research Ethics Committee. All participants provided written informed consent. Findings will be shared with all trial participants, and the general public, as well as the scientific community. Trial Registration ISRCTN 30265294 (DOI: 10.1186/ISRCTN30265294), UKCRN

    Full Text Available Crossbite can be treated using both removable and fixed appliances. This paper describes the report of two cases by a method of treating anterior single tooth in crossbite which is locked out of arch form with a simple fixed partial appliance. Orthodontic treatment was initiated by creating space for the locked out incisor using open coil spring and further corrected using MBT brackets and nitinol archwire for alignment. Treatment goals were achieved, and esthetics and occlusion were maintained postoperatively. Treatment objectives were obtained within a short duration using this technique, and there was an improvement in patients' smile.

    It remains unclear which methotrexate protocol for the treatment of ectopic pregnancy has a higher success rate or a higher adverse effect rate. To compare the treatment success rates and adverse effect rates of single-dose and non-single-dose (two-dose and multi-dose) methotrexate protocols in the treatment of ectopic pregnancy. Various databases including Medline, Embase, and the Cochrane Central Register of Controlled Trials were searched on July 1, 2017, using search terms including "methotrexate" and "pregnancy." Randomized controlled trials comparing different methotrexate protocols for the treatment of ectopic pregnancy were included. Relative risks (RRs) and 95% confidence intervals (CIs) were calculated to compare treatment success rates and adverse effect rates. The single-dose and non-single-dose protocols had similar success rates (RR 1.00, 95% CI 0.96-1.04; 11 trials, 1121 patients, I 2 =18%). The non-single-dose protocols had a higher adverse effect rate than did the single-dose protocol (RR 0.73, 95% CI 0.59-0.91; nine trials, 934 patients, I 2 =0%). The single-dose methotrexate protocol was the optimal protocol for the medical treatment of ectopic pregnancy. © 2018 International Federation of Gynecology and Obstetrics.

    The primary goal of this study was to assess the suitability of (11)C-Pittsburgh compound B ((11)C-PiB) blood-brain barrier delivery (K1) and relative delivery (R1) parameters as surrogate indices of cerebral blood flow (CBF), with a secondary goal of directly examining the extent to which simplified uptake measures of (11)C-PiB retention (amyloid-β load) may be influenced by CBF, in a cohort of controls and patients with mild cognitive impairment (MCI) and Alzheimer disease (AD). Nineteen participants (6 controls, 5 AD, 8 MCI) underwent MR imaging, (15)O-water PET, and (11)C-PiB PET in a single session. Fourteen regions of interest (including cerebellar reference region) were defined on MR imaging and applied to dynamic coregistered PET to generate time-activity curves. Multiple analysis approaches provided regional (15)O-water and (11)C-PiB measures of delivery and (11)C-PiB retention that included compartmental modeling distribution volume ratio (DVR), arterial- and reference-based Logan DVR, simplified reference tissue modeling 2 (SRTM2) DVR, and standardized uptake value ratios. Spearman correlation was performed among delivery measures (i.e., (15)O-water K1 and (11)C-PiB K1, relative K1 normalized to cerebellum [Rel-K1-Water and Rel-K1-PiB], and (11)C-PiB SRTM2-R1) and between delivery measures and (11)C-PiB retention, using the Bonferroni method for multiple-comparison correction. Primary analysis showed positive correlations (ρ ≈0.2-0.5) between (15)O-water K1 and (11)C-PiB K1 that did not survive Bonferroni adjustment. Significant positive correlations were found between Rel-K1-Water and Rel-K1-PiB and between Rel-K1-Water and (11)C-PiB SRTM2-R1 (ρ ≈0.5-0.8, P PiB retention and relative (11)C-PiB delivery measures (but not (15)O-water delivery measures) in primary cortical areas that arose only after accounting for cerebrospinal fluid dilution. (11)C-PiB SRTM2-R1 is highly correlated with regional relative CBF, as measured by (15)O-water K1

    African pygmy hedgehogs (Atelerix albiventris) are popular pets belonging to the Erinaceidae family of spined mammals. Amongst the most common skin diseases occurring in this species is infestation caused by the mite Caparinia spp. Due to their skin anatomy and spiny coat, detection of skin lesions in these hedgehogs can be difficult. This may result in delays in seeking medical care, which may lead to secondary bacterial infection and self-inflicted trauma. Multiple therapies have been used in the treatment of this skin condition including ivermectin, amitraz, fipronil and selamectin. A drug which could be administered as a single oral dose would be advantageous to these pets and their owners. To evaluate the effect of a single oral dose (15 mg/kg) of fluralaner on Caparinia tripilis infestation in the African pygmy hedgehog. A 10-month-old African pygmy hedgehog weighing 184 g. Response to treatment was monitored by dermatological examination and superficial skin scrapings repeated at 7, 14, 21, 30, 60, 90 and 120 days following fluralaner administration. On Day 7 after treatment, adult mites were observed exhibiting normal movement. On Day 14, only dead mites were observed. No life stages of the mites were found after Day 21. A single oral dose at 15 mg/kg of fluralaner was effective within 21 days after treatment for capariniasis in this case. Further studies are required to evaluate the drug's safety and toxicology in hedgehogs, and to confirm efficacy. © 2017 ESVD and ACVD.

    The burden of revision arthroplasty surgery for infection is rising as the rate of primary arthroplasty surgery increases. Infected arthroplasty rates are now relatively low, but the sheer increase in volume is leading to considerable patient morbidity and significant increases in costs to the health care system. Single-stage revision for infection is one of the several accepted treatment options, but the indications and results are debated. This review aims to clarify the current evidence. MEDLINE/PubMed databases were reviewed for studies that looked at single- or one-stage revision knee or hip arthroplasty for infection. There is increasing evidence that single-stage revision for infection can control infection and with decreased morbidity, mortality, and health care costs compared with a staged approach. However, the indications are still debated. Recently, there has been a determined effort to define an infected arthroplasty in a manner that will allow for standardization of reporting in the literature. The evidence supporting single stage for knee arthroplasty is catching up with the result with hip arthroplasty. High-quality data from randomized controlled trials are now pending. After the gradual evolution of using the single-stage approach, with the widespread acceptance of this definition, we can now standardize comparisons across the world and move toward a refined definition of the ideal patient population for single-stage arthroplasty revision in both the hip and the knee population.

    To investigate the efficacy of progressive addition lenses on the treatment of ametropia and loss of accomodation after the single eye's IOL implantation. Eighty four patients undergoing IOL implantation in single eyes were prescribed with progressive addition lenses for ametropia correction and regularly followed up to observe subsequent correction effect. Among these 84 patients, 72 could comfortably adapt to the use of progressive addition lenses to improve visual acuity and accomondation, while the remaining 12 patients failed to accomodate the usage of progressive addition lenses. Wearing progressive addition lenses acts as a relatively feasible approach to improve visual acuity and alleviate disorders of accomodation for patients who underwent IOL implantation in single eyes. The patients should be prescribed with progressive lenses under professional instructions and guidance.

    While complex symptom scales are important research tools, simpler, preferably single item scales may be more useful for routine clinical practise in the evaluation of patients with overactive bladder syndrome (OAB). This study aimed to compare multiple single-item scales at baseline and after treatment with patient-reported overall rating of treatment efficacy. In a pre-planned secondary analysis of a previously reported observational study, 4,450 patients were evaluated at baseline and after 12 weeks open-label treatment with solifenacin. Apart from episode counting for classical OAB symptoms, the following single-item rating scales were applied: Indevus Urgency Severity Scale, Urgency Perception Scale, a Visual Analog Scale (VAS), quality of life question of the IPSS, and general health and bladder problem questions of the King's Health Questionnaire (KHQ). At baseline OAB symptoms correlated at best moderately with each (r = 0.285-0.508) other or with any of the rating scales (r = 0.060-0.399). Pair-wise correlations between treatment-associated symptom or scale improvements tended to be tighter (r = 0.225-0.588). When compared to patient-reported efficacy, the VAS (r = 0.487) and the bladder problem question of the KHQ (r = 0.452) showed the tightest correlation, whereas all symptom and rating scale improvements exhibited poor correlation with patient-reported tolerability (r ≤ 0.283). The VAS and the bladder problem question of the KHQ show the greatest promise as single-item scales to assess problem intensity in OAB patients. Copyright © 2011 Wiley-Liss, Inc.

    The purpose of this study was to evaluate the effect of 2.5°C cold saline irrigation as final irrigant on postoperative pain after single-visit root canal treatment of teeth with vital pulps. One-hundred and seventy patients were assessed as eligible and included to the study. The teeth were randomly divided into two groups (n = 85) (i.e. the control group and the cryotherapy group). In the cryotherapy group, final irrigation with 2.5°C 0.9% physiological saline solution for 5 min was performed following completion of biomechanical preparation, whereas in control group same solution stored at the root temperature was used. Treatments were performed in a single visit. Participants were asked to rate the intensity of their postoperative pain using visual analogue scale at 24 and 48 h. Data were analysed by Mann-Whitney U test and Student's t test. In the cryotherapy group level of reported postoperative pain was significantly lower than the control group (P < 0.05, Mann-Whitney U test). The outcome of this investigation indicates that 2.5°C cold saline irrigation as final irrigant can result a significant reduction in postoperative pain levels in comparison to the control group. Cryotherapy is a simple, cost-effective, and non-toxic option for postoperative pain control in single visit root canal treatment. © 2016 Australian Society of Endodontology Inc.

    The increasing use of high-fidelity simulation is limited by the imbalance between the growing number of students and the human resources available in such a way that all residents cannot play a role during scenarios. The learning outcomes of observers need to be studied. This prospective randomised study was approved by the institutional review board. Anaesthesia residents attending a one-day training session were enrolled. In each of the four scenarios, three residents played an active role while others observed in a separate room. All participants attended debriefing sessions. Residents were randomised between active participant-observer group (AP-O group) and observer group (O group). A similar questionnaire was distributed before, immediately after the session and after three months and included self-reported assessment of satisfaction, medical knowledge (noted 0-16), and non-technical skills. A hundred and four questionnaires were analysed. Immediately after the simulation, a significant increase in medical knowledge was recorded but was higher in the AP-O group (6 [5-8] to 10 [8-11]/16) than in the O group (7 [5-8] to 9 [7-10]/16). High scores for non-technical skills were similarly observed in both groups. Satisfaction was high in both groups but was higher in the AP-O group (9 [8-9] versus 8 [8-9]/10, P=0.019). Decay of knowledge was observed for most main outcomes at three months. This study suggests an immediate improvement of learning outcomes for both roles after immersive simulation but some learning outcomes may be better for residents engaged as players in scenarios.

    Full Text Available People are often more likely to accept risky monetary gambles with positive expected values when the gambles will be played more than once. We investigated whether this distinction between single-play and multiple-play gambles extends to medical treatments for individual patients and groups of patients. Resident physicians and medical students (extit{n} = 69 and undergraduates (extit{n} = 99 ranked 9 different flu shots and a no-flu-shot option in 1 of 4 combinations of perspective (individual patient vs. group of 1000 patients and uncertainty frame (probability vs. frequency. The rank of the no-flu-shot option (a measure of preference for treatment vs. no treatment was not significantly related to perspective or participant population. The main effect of uncertainty frame and the interaction between perspective and uncertainty frame approached significance (0.1 {extgreater} extit{p} {extgreater} 0.05, with the no-flu-shot option faring particularly poorly (treatment faring particularly well when decisions about many patients were based on frequency information. Undergraduate participants believed that the no-flu-shot option would be less attractive (treatment would be more attractive in decisions about many patients, but these intuitions were inconsistent with the actual ranks. These results and those of other studies suggest that medical treatments for individuals and groups are not analogous to single-play and multiple-play monetary gambles, perhaps because many people are unwilling to aggregate treatment outcomes over patients in the same way that they would compute net gains or losses over monetary gambles.

    Stereotactic-Radio-Surgery (SRS) using Conformal-Arc-Therapy (CAT) is a well established irradiation technique for treatment of intracranial targets. Although small safety margins are required because of very high accuracy of patient positioning and exact online localisation, there are still disadvantages like long treatment time, high number of monitor units (MU) and covering of noncircular targets. This planning study analysed whether Rapid Arc (RA) with stereotactic localisation for single-fraction SRS can solve these problems. Ten consecutive patients were treated with Linac-based SRS. Eight patients had one or more brain metastases. The other patients presented a symptomatic vestibularis schwannoma and an atypic meningeoma. For all patients, two plans (CAT/RA) were calculated and analysed. Conformity was higher for RA with additional larger low-dose areas. Furthermore, RA reduced the number of MU and the treatment time for all patients. Dose to organs at risk were equal or slightly higher using RA in comparison to CAT. RA provides a new alternative for single-fraction SRS irradiation combining advantages of short treatment time with lower number of MU and better conformity in addition to accuracy of stereotactic localisation in selected cases with uncomplicated clinical realization

    The toxic effect of single and binary treatments of synthetic and plant-derived molluscicides was studied against the harmful terrestrial snail Achatina fulica. In single treatments, among the synthetic molluscicides Snail Kill and cypermethrin were potent, whereas Cedrus deodara oil was more toxic among molluscicides of plant origin against A. fulica. In binary treatments, a combination of Cedrusdeodara + Alliumsativum was more toxic. The toxicities of these single and binary treatments of synthetic and plant-derived molluscicides were dose and time dependent. Copyright 2002 John Wiley & Sons, Ltd.

    Default from tuberculosis (TB) treatment could exacerbate the disease and result in the emergence of drug resistance. This study identified the risk factors for default from TB treatment in Korea. This single-center case-control study analyzed 46 default cases and 100 controls. Default was defined as interrupting treatment for 2 or more consecutive months. The reasons for default were mainly incorrect perception or information about TB (41.3%) and experience of adverse events due to TB drugs (41.3%). In univariate analysis, low income (defaulter (15.2% vs. 2.0%, P = 0.005), and combined extrapulmonary TB (54.3% vs. 34.0%, P = 0.020) were significant risk factors for default. In multivariate analysis, the absence of TB stigma (adjusted odd ratio [aOR]: 46.299, 95% confidence interval [CI]: 8.078-265.365, P defaulters (aOR: 33.226, 95% CI: 2.658-415.309, P = 0.007), and low income (aOR: 5.246, 95% CI: 1.249-22.029, P = 0.024) were independent predictors of default from TB treatment. In conclusion, patients with absence of disease stigma, treated by a non-pulmonologist, who were former defaulters, and with low income should be carefully monitored during TB treatment in Korea to avoid treatment default.

    The response of cells to a chemical or biological agent in terms of their impedance changes in real-time is a useful mechanism that can be utilized for a wide variety of biomedical and environmental applications. The use of a single-cell-based analytical platform could be an effective approach to acquiring more sensitive cell impedance measurements, particularly in applications where only diminutive changes in impedance are expected. Here, we report the development of an on-chip cell impedance biosensor with two types of electrodes that host individual cells and cell populations, respectively, to study its efficacy in detecting cellular response. Human glioblastoma (U87MG) cells were patterned on single- and multi-cell electrodes through ligand-mediated natural cell adhesion. We comparatively investigated how these cancer cells on both types of electrodes respond to an ion channel inhibitor, chlorotoxin (CTX), in terms of their shape alternations and impedance changes to exploit the fine detectability of the single-cell-based system. The detecting electrodes hosting single cells exhibited a significant reduction in the real impedance signal, while electrodes hosting confluent monolayer of cells showed little to no impedance change. When single-cell electrodes were treated with CTX of different doses, a dose-dependent impedance change was observed. This enables us to identify the effective dose needed for this particular treatment. Our study demonstrated that this single-cell impedance system may potentially serve as a useful analytical tool for biomedical applications such as environmental toxin detection and drug evaluation.

    The aim of this work was to develop a method for processing ripe olives with a single NaOH treatment (lye) instead of the well-known 3 lye treatments. Olives of the Hojiblanca variety were processed according to the 2 processes and the color, firmness, flavor, and content in phenolic compounds of the final product were similar in both cases but concentration in triterpenic acids was highest in the olives from the single lye treatment. In this process the concentration of NaOH must range between 20 and 35 g/L, especially to obtain good texture when working at 20 °C. If temperature during the oxidation up to 27 °C the firmness of olives was significantly decreased. The concentration of the NaOH did not exert a high effect on the color of the final product, although firmness decreased as the strength of the lye increased. Higher contents in phenolic compounds and triterpenic acids were also found in the olives processed with the lowest NaOH concentration tested (20 g/L). This new process reduces the volume of wastewaters and energy consumption, and gives rise to a product which is richer in bioactive substances than the traditionally processed one. © 2016 Institute of Food Technologists®.

    To describe a fixation technique of the medial and central fat pads in the subperiosteal pocket for transconjunctival fat transposition, using a single subdermal, non-removable, non-absorbable stitch. Retrospective study of 19 patients with bilateral deep tear through treated by means of transconjunctival fat transposition. Charts and photographic records were reviewed. Photographical and clinical improvement of the deep tear through and fat prolapse was observed in all patients in variable degrees. There were no intraoperative complications. Significant periocular hematoma occurred in 1 patient and solved without complications. Two patients presented transitory fat pedicle hardening and one patient presented a conjunctival inferior fornix granuloma, surgically removed. All patients were satisfied. Transconjunctival subperiosteal fat transposition with single subdermal stitch to fix the medial and central fat pads, for the treatment of deep tear trough and fat prolapse demonstrated high patient satisfaction, good aesthetic results with no significant or permanent complications.

    Intensity-modulated particle therapy (IMPT) for tumors showing interfraction motion is a topic of current research. The purpose of this work is to compare three treatment strategies for IMPT to determine potential advantages and disadvantages of ion prostate cancer therapy. Simulations for three treatment strategies, conventional one-plan radiotherapy (ConvRT), image-guided radiotherapy (IGRT), and online adaptive radiotherapy (ART) were performed employing a dataset of 10 prostate cancer patients with six CT scans taken at one week intervals. The simulation results, using a geometric margin concept (7-2 mm) as well as patient-specific internal target volume definitions for IMPT were analyzed by target coverage and exposure of critical structures on single fraction dose distributions. All strategies led to clinically acceptable target coverage in patients exhibiting small prostate motion (mean displacement < 4 mm), but IGRT and especially ART led to significant sparing of the rectum. In 20 % of the patients, prostate motion exceeded 4 mm causing insufficient target coverage for ConvRT (V95 mean = 0.86, range 0.63-0.99) and IGRT (V95 mean = 0.91, range 0.68-1.00), while ART maintained acceptable target coverage. IMPT of prostate cancer demands consideration of rectal sparing and adaptive treatment replanning for patients exhibiting large prostate motion. (orig.) [de

    Chordoma is a radioresistant tumor that presents a therapeutic challenge with spine involvement, as high doses of radiation are needed for local control while limiting dose to the spinal cord. The purpose of this study is to determine the efficacy and safety of single-fraction spine stereotactic body radiation therapy for the treatment of spine chordoma. A retrospective review of our institutional database from 2006 to 2013 identified 8 patients (12 cases) with chordoma of the spine who were treated with spine stereotactic body radiation therapy. Surgical resection was performed in 7 of the 12 cases. The treatment volume was defined by the bony vertebral level of the tumor along with soft tissue extension appreciated on magnetic resonance imaging fusion. Medical records and imaging were assessed for pain relief and local control. Treatment toxicity was evaluated using Common Terminology Criteria for Adverse Events version 4.0. Median age was 59 years (range, 17-91). Median target volume was 48 cm 3 (1-304), and median prescription dose was 16 Gy (11-16). Median conformality index was 1.44 (1.14-3.21), and homogeneity index was 1.12 (1.05-1.19). With a median follow-up time of 9.7 months (.5-84), local control was achieved in 75% of the cases treated. One patient developed limited grade 2 spinal cord myelopathy that resolved with steroids. There were no other treatment toxicities from spine stereotactic body radiation therapy. Single-fraction spine stereotactic body radiation therapy can be safely delivered to treat chordoma of the spine with the potential to improve pain symptoms. Although the early data are suggestive, long-term follow-up with more patients is necessary to determine the efficacy of spine stereotactic body radiation therapy in the treatment of chordoma of the spine.

    Court Brown and Doll identified over 14,000 patients with ankylosing spondylitis who had been treated with one or more courses of x-irradiation from 1935 to 1954 at one of 87 radiotherapy centers in Great Britain and Northern Ireland. The first reports from this study analyzed mortality among these patients from leukemia and other causes, particularly cancer, but these analyses included many patients who had been treated with x-rays for their spondylitis more than once. This complicated the interpretation of the late effects of the treatment on mortality, as it was not clear to what extent the subsequent treatments contributed to the excess of deaths that persisted for many years after the first treatment. Smith and Doll (1982) avoided this difficulty by examining the death rate from leukemia and other radiation-induced cancers at different times after a single course of treatment. A comparison of the mortality of this group with the mortality of Japanese atomic bomb survivors revealed good agreement between the two studies, thus increasing confidence in the belief that both studies are giving sensible estimates of the risk of cancer from high doses of radiation. The follow-up of those spondylitic patients who received a single course of treatment only has recently been extended until the end of 1982, that is, for an additional 13 years. A further 1406 patients are now known to have died, including an additional 335 deaths for which the certified cause is cancer. Detailed results of this further follow-up will be presented

    We present a single-centre experience of procedural complications suffered by patients undergoing endovascular treatment for a ruptured saccular intracranial aneurysm at Tampere University Hospital, Finland, between 2000 and 2014. From 2000 to 2014, we treated 1,253 patients with aneurysmal subarachnoid haemorrhage, 491 of whom received endovascular treatment. Clinical data were collected retrospectively from the hospital's aneurysm database. A procedural complication was defined as having occurred whenever there was a documented new event in the patient's medical records or a note of a technical complication written by an interventionist after endovascular treatment. Procedural complications could be with or without clinical symptoms. Nearly 40% (491/1253) of the patients were treated with the endovascular method. Procedural complications occurred in 11.4% (56/491) of cases. The morbidity rate was 4.5% (22/491) and the mortality rate was 0.2% (1/491). Of the 56 complications, ischaemic complications occurred in 52% (29/56), haemorrhagic complications occurred in 27% (15/56) and technical complications occurred in 21% (12/56) of cases. In 61% (34/56) of the cases, the procedural complication did not cause any clinical symptoms. The total risk for procedural complications leading to postoperative disability or death at our institute was 4.7%. The complication frequency is in accordance with previous reports. Endovascular treatment of ruptured intracranial aneurysms is a safe treatment method when patient selection is carefully performed.

    1982-01-01

    Mortality was studied in 14,111 patients with ankylosing spondylitis given a single course of x-ray treatment during 1935-54. Mortality from all causes was 66% greater than that of the general population of England and Wales. The substantial excesses of deaths from non-neoplastic conditions appeared to be associated with the disease itself rather than its treatment. A nearly fivefold excess of deaths from leukaemia and a 62% excess of deaths from cancers of sites that would have been in the radiation fields (''heavily irradiated sites'') were likely to have been a direct consequence of radiation treatment. Excess death rate from leukaemia was greatest three to five years after treatment and close to zero after 18 years. Excess of cancers of heavily irradiated sites did not become apparent until nine or more years after irradiation continuing for a further 11 years. More than 20 years after irradiation the excess risk declined but the fall was not statistically significant. The number of cancers of sites not considered to be in the radiation beams was 20% greater than expected. This excess, although not statistically significant, may have been due to scattered radiation. The risk of a radiation-induced leukaemia or other cancer was related to age at treatment time.

    In order to assess the usefulness of thallium-201 single-photon emission tomography (SPET) in the treatment follow-up of nasopharyngeal carcinoma (NPC), a total of 75 {sup 201}Tl SPET studies were performed in 18 patients with histologically proven NPC. The findings were compared with those of magnetic resonance imaging (MRI) before and after therapy. Four patients received radiotherapy alone while the other 14 received concurrent chemo-radiotherapy. Treatment response was classified as complete (CR) or partial (PR) based on the findings of MRI and {sup 201}Tl SPET. Intense {sup 201}Tl uptake by the tumour was seen in all 18 patients before treatment. After treatment, MRI showed seven CRs and 11 PRs, whereas {sup 201}Tl SPET showed 13 CRs and five PRs. In 12 patients, the results of {sup 201}Tl SPET were in agreement with those of MRI. In six patients MRI showed PR but {sup 201}Tl showed CR. Follow-up (mean 10.6 months) MRI and {sup 201}Tl SPET studies of these six patients revealed that tumour gradually decreased and finally vanished in three patients. This preliminary study indicates that {sup 201}Tl SPET has potential in the assessment of early response to treatment of patients with NPC when compared with MRI. (orig.)

    We treated gonococcal urethritis in men with a single 2 g dose of azithromycin extended-release formulation (azithromycin-SR) to determine its microbiological outcomes and tolerability. We enrolled 189 Japanese men with gonococcal urethritis between April 2009 and December 2013. The patients were given a single 2 g dose of azithromycin-SR. Microbiological efficacy was evaluated by the results of the post-treatment molecular testing of Neisseria gonorrhoeae. MIC testing was performed only for pretreatment isolates of N. gonorrhoeae collected from the patients. We evaluated 130 patients for microbiological outcomes. Of these patients, 122 (93.8%) were judged to be microbiologically cured on the basis of negative test results. All isolates for which the azithromycin MICs were ≤0.25 mg/L were eradicated, whereas 5 of 12 isolates for which the MICs were 1 mg/L persisted after the treatment. Forty-six adverse events occurred in 41 patients. However, all adverse events were classified as mild. The eradication rate of N. gonorrhoeae was 93.8% in men with gonococcal urethritis treated with a single 2 g dose of azithromycin-SR. The breakpoint MIC of a 2 g dose of azithromycin-SR for gonococcal urethritis associated with clinical treatment failures appeared to be 1 mg/L. With regard to side effects of higher doses of azithromycin, the 2 g dose of azithromycin-SR appeared to improve tolerability. However, the widespread use of a high-dose regimen of azithromycin might lead to the development of further resistance to azithromycin. © The Author 2014.

    To evaluate an alternative monitoring protocol without day 4 β-human chorionic gonadotropin (β-hCG) measurement for predicting the need for a repeated methotrexate (MTX) dose in patients undergoing single-dose MTX therapy for ectopic pregnancy (EP). Single-center retrospective study (Canadian Task Force classification II-3). University-affiliated hospital. Included in the study were 184 EP patients treated with MTX between January 2009 and December 2016. Single-dose MTX treatment (50 mg/m 2 ). The patients were treated with repeated doses of MTX every 7 days, if necessary, according to Stovall's protocol, or with laparoscopic surgery in cases of tubal rupture. The success of a single-dose of MTX according to the alternative measure was defined as a >50% decrease in the β-hCG level between days 1 and 7 in clinically stable patients. The sensitivity, specificity, false-negative rate, false-positive rate, and attributable risk of this new monitoring measure were calculated and compared with the traditional regimen. The new protocol had a sensitivity and specificity of 100% and 88.7%, respectively, for predicting a required second dose in patients whose day 1 β-hCG levels were <2000 mIU/mL. For patients with day 1 β-hCG level ≥2000 mIU/mL, both monitoring regimens had the same efficiency. The new monitoring model without the day 4 β-hCG measurement may offer both patients and clinicians multiple options to monitor single-dose MTX therapy for selected EP patients, with a comparable clinical efficiency to Stovall's protocol and less expense and follow-up burden to patients.

    2015-09-01

    Homework is a key component of Cognitive Therapy (CT) for depression. Although previous research has found evidence for a positive relationship between homework compliance and treatment outcome, the methods used in previous studies have often not been optimal. In this study, we examine the relation of specific aspects of homework engagement and symptom change over successive session-to-session intervals. In a sample of 53 depressed adults participating in CT, we examined the relation of observer-rated homework engagement and session-to-session symptom change across the first five sessions. Within patient (and not between patient) variability in homework engagement was significantly related to greater session-to-session symptom improvements. These findings were similar when homework engagement was assessed through a measure of general engagement with homework assignments and a measure assessing engagement in specific assignments often used in CT. Secondary analyses suggested that observer ratings of the effort patients made on homework and the completion of cognitive homework were the numerically strongest predictors of depressive symptom improvements. Patient engagement with homework assignments appears to be an important predictor of early session-to-session symptom improvements. Future research is needed to identify what therapist behaviors promote homework engagement. Copyright © 2015 Elsevier Ltd. All rights reserved.

    The use of Human Reliability Analysis (HRA) to identify and resolve human factors issues has significantly increased over the past two years. Today, utilities, research institutions, consulting firms, and the regulatory agency have found a common application of HRA tools and Probabilistic Risk Assessment (PRA). The ''1985 IEEE Third Conference on Human Factors and Power Plants'' devoted three sessions to the discussion of these applications and a review of the insights so gained. This paper summarizes the three sessions and presents those common conclusions that were discussed during the meeting. The paper concludes that session participants supported the use of an adequately documented ''living PRA'' to address human factors issues in design and procedural changes, regulatory compliance, and training and that the techniques can produce cost effective qualitative results that are complementary to more classical human factors methods

    2013-01-01

    Research has confirmed the effectiveness of medications, when used in conjunction with ongoing counseling, to treat substance abuse disorders. This article describes a national, mixed-methods research project designed to investigate single state authorities’ (SSAs) perceptions of adoption of evidence-based practices in substance abuse treatment. Results are focused specifically on medication-assisted treatment, one of five evidence-based practices defined by the National Quality Forum. Medication-assisted treatment (MAT) is an important and effective part of comprehensive care options available to clients who are chronically ill with alcohol and other drug disorders. Despite mounting clinical evidence and increased availability, overall rates of implementation and sustained adoption of medications to treat addiction remain limited. The results illustrate that the SSA representatives who fund public treatment programs believe MAT is a priority and worthy of system-wide implementation. Current strategies utilized by SSAs to support the adoption of MAT are detailed, as are barriers to adoption and implementation. PMID:21138199

  8. Formula to estimate the thermal enhancement ratio of a single simultaneous hyperthermia and radiation treatment

    1984-01-01

    An experimental model composed of a C 3 H mammary carcinoma and its surrounding skin has been exposed to simultaneous radiation and hyperthermia given with different combinations of the heating time and temperature. Based on the thermal enhancement ratio (TER) values obtained in the temperature range 41.5 to 43.5 0 C, a linear relationship between TER and the heating time was achieved at each temperature. The slopes of the curves drawn at each temperature were found to have a log-linear relationship with the treatment temperature. With these relationships it was possible to make a formula expressing the TER as a function of treatment temperature and time. This formula gives a crude but probably acceptable estimate of the TER following a single simultaneous radiation and heat treatment. Although subject to several limitations, the formula represents an attempt to describe a heat dose concept for the radiosensitizing effect of hyperthermia. This may be useful to establish the tolerance level of a given radiation treatment when combined with hyperthermia. (Auth.)

    Sacroiliac joint pain can be managed by intra-articular injections or radiofrequency of its innervation. Single strip lesions radiofrequency denervation is a new system. The objective of this study was to present one of the first utilizations of this innovative technique. 60 patients who met the diagnostic criteria for sacroiliac joint syndrome were enrolled in the study. In total, 102 single strip lesions radiofrequency denervations were performed. Pain intensity was measured with the Oswestry low back pain disability questionnaire and the Oswestry Disability Index whose scores were assessed at 1, 3, 6 and 12 months after the procedure. 91.8 % of the 102 radiofrequency treatments resulted in a reduction of more than 50% pain intensity relief at 1 month, 81.6% at 3 months and 59.16% at 6 months. In 35.7% of cases, the relief was continuative up to 1 year. No relief was observed in 12.24% of cases. The ODI scores improved significantly 1 month after the procedure, compared with the baseline scores. The ODI scores after 6 months improved very clearly compared with the baseline scores and with the 3-month scores. Single strip lesions radiofrequency denervation using the Simplicity III probe is a potential modality for intermediate term relief for patients with sacroiliac pain.

    The aim of this study was to analyze the patterns of care and treatment outcomes in patients with primary thyroid lymphoma (PTL) in a single institution. Medical records of 29 patients with PTL treated between April 1994 and February 2012 were retrospectively reviewed. Diagnosis was confirmed by biopsy (n = 17) or thyroidectomy (n = 12). Treatment modality and outcome were analyzed according to lymphoma grade. The median follow-up was 43.2 months (range, 3.8 to 220.8 months). The median age at diagnosis was 57 years (range, 21 to 83 years) and 24 (82.8%) patients were female. Twenty-five (86.2%) patients had PTL with stage IEA and IIEA. There were 8 (27.6%) patients with mucosa-associated lymphoid tissue (MALT) lymphoma and the remaining patients had high-grade lymphoma. Patients were treated with surgery (n = 2), chemotherapy (n = 7), radiotherapy (n = 3) alone, or a combination of these methods (n = 17). Treatment modalities evolved over time and a combination of modalities was preferred, especially for the treatment of high-grade lymphoma in recent years. There was no death or relapse among MALT lymphoma patients. Among high-grade lymphoma patients, 5-year overall survival (OS) and 5-year progression-free survival (PFS) were 75.6% and 73.9%, respectively. Complete remission after initial treatment was the only significant prognostic factor for OS (p = 0.037) and PFS (p = 0.003). Patients with PTL showed a favorable outcome, especially with MALT lymphoma. Radiotherapy alone for MALT lymphoma and chemotherapy followed by radiotherapy for high-grade lymphoma can be effective treatment options for PTL.

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

    Recently, many universities have implemented programmes in which therapy dogs and their handlers visit college campuses. Despite the immense popularity of therapy dog sessions, few randomized studies have empirically tested the efficacy of such programmes. The present study evaluates the efficacy of such a therapy dog programme in improving the well-being of university students. This research incorporates two components: (a) a pre/post within-subjects design, in which 246 participants completed a brief questionnaire immediately before and after a therapy dog session and (b) an experimental design with a delayed-treatment control group, in which all participants completed baseline measures and follow-up measures approximately 10 hr later. Only participants in the experimental condition experienced the therapy dog session in between the baseline and follow-up measures. Analyses of pre/post data revealed that the therapy dog sessions had strong immediate benefits, significantly reducing stress and increasing happiness and energy levels. In addition, participants in the experimental group reported a greater improvement in negative affect, perceived social support, and perceived stress compared with those in the delayed-treatment control group. Our results suggest that single, drop-in, therapy dog sessions have large and immediate effects on students' well-being, but also that the effects after several hours are small.

We examined the efficacy and safety of adding chemotherapy to Regorafenib for the treatment of metastatic colorectal cancer(mCRC patients.We recruited mCRC patients at our institute who received either regorafenib monotherapy or regorafenib in combination with other chemotherapies. All patients had received chemo and target therapies and presented with disease progression before regorafenib treatment. The primary end point was overall survival.Between September1, 2015 and May 31, 2017, 100 mCRC patients at our institute received regorafenib treatment. 39 patients were excluded due to poor performance, lack of timely treatment, or inadequate clinical data. A total of 34 patients received regorafenib combined with other chemotherapies, and 27 patients received regorafenib alone. Median follow up time was 10.4 and 6.1 months, respectively. The primary end point of median OS was higher in the combination group than in the single use group (20.9m vs 10.3m, p = 0.015. The most frequent adverse events were hand-foot skin reactions(16[47.1%]vs 12[44.4%], fatigue(6[17.6%] vs 7[25.9%], gastrointestinal discomfort (7[20.6%] vs 6[22.2%], neutropenia (4[11.8%] vs 1[3.7%], diarrhea(4[11.8%] vs 1[3.7%], and mucositis(5[14.7%] vs 1[3.7%].The present study showed the efficacy and side effects of regorafenib combination treatment. Superiority in median OS and median PFS was noted in the combination group. The sampling difference between the study and observation groups effects justifies the comparison. Further clinical evidence of combination therapy efficacy is pending future studies.

    2010-09-01

    Full Text Available Abstract Background Our recent investigations have demonstrated that cell cultures from subjects, who received a single spinal manipulative treatment in the upper thoracic spine, show increased capacity for the production of the key immunoregulatory cytokine, interleukin-2. However, it has not been determined if such changes influence the response of the immune effector cells. Thus, the purpose of the present study was to determine whether, in the same subjects, spinal manipulation-related augmentation of the in vitro interleukin-2 synthesis is associated with the modulation of interleukin 2-dependent and/or interleukin-2-induced humoral immune response (antibody synthesis. Methods A total of seventy-four age and sex-matched healthy asymptomatic subjects were studied. The subjects were assigned randomly to: venipuncture control (n = 22, spinal manipulative treatment without cavitation (n = 25 or spinal manipulative treatment associated with cavitation (n = 27 groups. Heparinized blood samples were obtained from the subjects before (baseline and then at 20 minutes and 2 hours post-treatment. Immunoglobulin (antibody synthesis was induced in cultures of peripheral blood mononuclear cells by stimulation with conventional pokeweed mitogen or by application of human recombinant interleukin-2. Determinations of the levels of immunoglobulin G and immunoglobulin M production in culture supernatants were performed by specific immunoassays. Results The baseline levels of immunoglobulin synthesis induced by pokeweed mitogen or human recombinant interleukin-2 stimulation were comparable in all groups. No significant changes in the production of pokeweed mitogen-induced immunoglobulins were observed during the post-treatment period in any of the study groups. In contrast, the production of interleukin-2 -induced immunoglobulin G and immunoglobulin M was significantly increased in cultures from subjects treated with spinal manipulation. At 20 min post

    Full Text Available Single tablet regimens (STRs for HIV infection improve patient satisfaction, quality of life, medication adherence, and virological suppression compared to multitablet regimens (MTRs. This is the first study assessing STR uptake and durability in Australia. This retrospective audit of all patients receiving an STR (n=299 at a large Sydney HIV clinic (January 2012–December 2013 assessed patient demographics, treatment prior to STR, HIV RNA load and CD4 during MTR and STR dosing, and reasons for STR switch. 206 patients switched from previous antiretroviral treatment to an STR, of which 88% switched from an MTR. Reasons for switching included desire to simplify treatment (57%, reduced side effects or toxicity (18%, and cost-saving for the patient. There was no switching for virological failure. Compared to when on an MTR, patients switching to an STR had significantly lower HIV RNA counts (p<0.001 and significantly higher CD4 counts (p<0.001. The discontinuation rate from STR was very low and all patients who switched to an STR maintained virological suppression throughout the study duration, although the study is limited by the absence of a control group.

    Haemophilus ducreyi (HD) and Treponema pallidum subspecies pertenue (TP) are major causative agents of cutaneous ulcer (CU) in the tropics. Azithromycin is recommended to treat sexually transmitted HD infections and has good in vitro activity against HD strains from both genital and skin ulcers. We investigated the efficacy of oral single-dose azithromycin on HD-CU. We conducted a community-based cohort study in Lihir Island, Papua New Guinea, from October 2014 through May 2016. Consenting patients with skin ulcers >1 cm in diameter were eligible for this study and had collected a lesional swab for polymerase chain reaction (PCR). All participants were treated with single-dose azithromycin (30 mg/kg) and were followed up for assessment of clinical resolution. We retrospectively classified patients according to PCR results into HD, TP, and PCR-negative groups. The primary endpoint was healing rates of HD-CU at 14 days after treatment. We obtained full outcome data from 246 patients; 131 (53.3%) were HD PCR positive, 37 (15.0%) were TP positive, and 78 (31.7%) were negative for all tests. Healing rates were 88.5% (95% confidence interval [CI], .82-.93) in the HD group, 78.4% [95% CI, .63-.89] in the TP group, and 74.4% (95% CI, .64-.83) in the PCR-negative group. If we included the participants with improved ulcers, the healing rates increased to 94.7%, 97.3%, and 89.7% respectively. HD cases classified as not healed all converted to HD-negative PCR. Based upon clinical resolution and PCR conversion to HD negative, a single oral dose of azithromycin is efficacious for the treatment of HD-CU. These results have implications for the treatment of individual patients and for the use of antibiotics in public health strategies to control CU in the tropics. © The Author 2017.

  1. Less is more: latent learning is maximized by shorter training sessions in auditory perceptual learning.

    Directory of Open Access Journals (Sweden)

    Katharine Molloy

    Full Text Available The time course and outcome of perceptual learning can be affected by the length and distribution of practice, but the training regimen parameters that govern these effects have received little systematic study in the auditory domain. We asked whether there was a minimum requirement on the number of trials within a training session for learning to occur, whether there was a maximum limit beyond which additional trials became ineffective, and whether multiple training sessions provided benefit over a single session.We investigated the efficacy of different regimens that varied in the distribution of practice across training sessions and in the overall amount of practice received on a frequency discrimination task. While learning was relatively robust to variations in regimen, the group with the shortest training sessions (∼8 min had significantly faster learning in early stages of training than groups with longer sessions. In later stages, the group with the longest training sessions (>1 hr showed slower learning than the other groups, suggesting overtraining. Between-session improvements were inversely correlated with performance; they were largest at the start of training and reduced as training progressed. In a second experiment we found no additional longer-term improvement in performance, retention, or transfer of learning for a group that trained over 4 sessions (∼4 hr in total relative to a group that trained for a single session (∼1 hr. However, the mechanisms of learning differed; the single-session group continued to improve in the days following cessation of training, whereas the multi-session group showed no further improvement once training had ceased.Shorter training sessions were advantageous because they allowed for more latent, between-session and post-training learning to emerge. These findings suggest that efficient regimens should use short training sessions, and optimized spacing between sessions.

  2. Analytical Treatment of Single Bunch Transverse Dynamics in Linacs with Wakefields

    Guignard, Gilbert

    1998-01-01

    In this paper we present an analytical treatment of the equation of motion of single bunch particles traveling in the linac of a linear collider, in the presence of wakefields. Using a somewhat simplified model, the equation is solved for a Gaussian distribution of charge, a linear variation of the wakefield along the bunch, a smooth focusing and in the absence of acceleration. The specificity of the method consists of preventing the appearance of artificial secular terms and keeping at any stage the intrinsic tune-shift that characterizes the problem and stabilizes the motion. Hence, a first order perturbation becomes sufficient provided that a non-standard perturbation expansion, specially developed for this analysis, be however applied. Solutions for the particle off-sets within the bunch are obtained and their contributions to the effective emittance calculated. The results explain the observed features of beam breakup and BNS damping, and reproduce the bunch dipole-oscillations visible on the animated gr...

  3. Purification of Single-Wall carbon nanotubes by heat treatment and supercritical extraction

    2011-09-01

    Full Text Available Arc discharge is the most practical method for the synthesis of single wall carbon nanotubes (SWCNT. However, the production of SWCNT by this technique has low selectivity and yield, requiring further purification steps. This work is a study of purification of SWCNT by heat treatment in an inert atmosphere followed by supercritical fluid extraction. The raw arc discharge material was first heat-treated at 1250 °C under argon. The nanotubes were further submitted to an extraction process using supercritical CO2 as solvent. A surfactant (tributylphosphate, TBP and a chelating agent (hexafluoroacetylacetone, HFA were used together to eliminate metallic impurities from the remaining arc discharge catalysts. Analysis of Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES showed an efficient removal of iron and cobalt (>80%. The purified nanotubes were further analyzed by TGA and Raman spectroscopy.

    Lymphoma of the conjunctiva is rare. It presents in older patients as a mass lesion and usually remains localized. Surgery is limited to biopsy, and radiation therapy is the definitive treatment of choice. The entire conjunctiva is treated. Relatively high doses (approximately 30 Gy) are required for local control, which may lead to cataract formation. Twelve patients with conjunctival lymphoma were treated at the Massachusetts General Hospital between 1979 and 1988. Ten of 12 patients presented with a unilateral lesion; 2 of 12 with bilateral lesions. Two of 12 patients were found to have systemic disease at the time of presentation. One patient developed conjunctival lymphoma 5 years after the diagnosis of generalized disease. Using electron beam, all patients were treated with a single anterior circular field to total doses ranging from 24 Gy to 30 Gy delivered in 8 to 16 fractions over 9 to 20 days. In all cases, the lens was shielded by a specially designed plastic contact lens bearing a 12 mm diameter lead shield. The lens dose was determined at varying depths beneath the shield for 6 MeV and 9 MeV electron beams and ranged from a minimum of 5% to an absolute maximum of 18% of the total dose delivered to the tumor. Local control was maintained in all patients with follow-up to 9 1/2 years. One patient relapsed distantly 3 years after treatment. One of 12 patients died of systemic disease 4 years after treatment of the ocular lesion. Two patients developed cataracts 4 and 5 years after treatment; one had bilateral cataract, although only one eye had been treated. Both patients were over 75 years old. In both cases, the cataracts were felt to be senile cataracts which are ophthalmologically and radiographically distinguishable from radiation induced lesions

    Surgical treatment of chronic pancreatitis is indicated for intractable pain. Frey's procedure is an accepted treatment for this disease. The aim of the present study was to describe a single-centre experience in the treatment of chronic pancreatitis using Frey's procedure. A retrospective analysis of 73 patients who underwent a Frey's procedure between 1991 to 2007 and had at least 1 year of follow-up. Demographics, indication for surgery, peri-operative complications and late outcomes were analysed. The median age was 39.9 years. Seventy out of the 73 (95.8%) patients were male. The median pre-operative body mass index (BMI) was 19.1 kg/m(2). All patients had abdominal pain, 34 (46.6%) of them daily and 13 (17.8%) weekly, with moderate or severe intensity in 98.6% (n= 72). The aetiology was secondary to alcohol in 70 patients (95.9%), with a median consumption of 278 g per day. The surgical morbidity rate was 28.7%; there were no deaths. Median post-operative follow-up was 77.0 months; 64 patients (91.4%) had complete pain relief and post-operative BMI was 22.4 kg/m(2) (P<0.001). All patients with pre-operative endocrine and exocrine insufficiencies showed no reversal of the situation. New onset insufficiencies appeared late. Frey's procedure was a safe and effective therapeutic option for the surgical treatment of patients with intractable pain caused by chronic pancreatitis. © 2011 International Hepato-Pancreato-Biliary Association.

    Full Text Available Aim: The aim of this study was to evaluate the clinical and radiological results in patients with severe hallux rigidus who underwent arthrodesis using single cortical screw. Methods: We retrospectively evaluated 18 patients (16 females, 2 males who underwent arthrodesis for severe hallux rigidus using single cortical screw. The mean age of the patients was 58.1 (range: 44-69 years. According to the Coughlin and Shurnas classification, 5 feet were rated as stage 3 and 13 feet were stage 4. 3 of the stage 3 patients had cheilectomy previously. The American Orthopaedic Foot and Ankle Society (AOFAS clinical rating scale for the metatarsophalangeal - interphalangeal joints was used for clinical evaluation. Hallux valgus angles and hallux dorsiflexion angles were measured on X-rays. Results: The mean follow-up period was 32.4 (range: 15-69 months. Radiological signs of non-union was found in one patient. The mean preoperative AOFAS score was 56.1 (range: 38-72. The mean final follow-up AOFAS score was found to be 81.1. Moderate results in 2 patients (11.1%, good results in 11 patients (61.1% and excellent results in 5 patients (27.8% were obtained. When the last X-rays were evaluated, 15.1° (7-24 valgus at the metatarsophalangeal joint and 11.9° (8-18 extension (to the floor at the metatarsophalangeal joint were detected. Late surgical wound healing was observed in one patient. The screws were removed due to irritation in 8 (44% patients. Conclusion: We assume that in the treatment of severe hallux rigidus, arthrodesis using a single cortical screw may be considered as a favorable surgical technique with its high union rates and increased functional results.

    Full Text Available Both in vitro and in vivo experiments have confirmed that platelet-rich plasma has therapeutic effects on many neuropathies, but its effects on carpal tunnel syndrome remain poorly understood. We aimed to investigate whether single injection of platelet-rich plasma can improve the clinical symptoms of carpal tunnel syndrome. Fourteen patients presenting with median nerve injury who had suffered from mild carpal tunnel syndrome for over 3 months were included in this study. Under ultrasound guidance, 1-2 mL of platelet-rich plasma was injected into the region around the median nerve at the proximal edge of the carpal tunnel. At 1 month after single injection of platelet-rich plasma, Visual Analogue Scale results showed that pain almost disappeared in eight patients and it was obviously alleviated in three patients. Simultaneously, the disabilities of the arm, shoulder and hand questionnaire showed that upper limb function was obviously improved. In addition, no ultrasonographic manifestation of the carpal tunnel syndrome was found in five patients during ultrasonographic measurement of the width of the median nerve. During 3-month follow-up, the pain was not greatly alleviated in three patients. These findings show very encouraging mid-term outcomes regarding use of platelet-rich plasma for the treatment of carpal tunnel syndrome.

    To investigate the treatment outcomes of parotid gland cancer at a single center over a 10-year period and to evaluate the prognostic significance of maximum standardized uptake value. Retrospective case series with chart review. Academic care center. Ninety-eight patients with primary parotid gland cancer who were surgically treated at Yonsei University Head & Neck Cancer Clinic between January 1999 and December 2008 were analyzed. Patient data were collected retrospectively from medical charts. The investigators analyzed the association of clinicopathological factors and maximum standardized uptake value on (18)F-fluorodeoxyglucose positron emission tomography-computed tomography scan with disease-specific survival. Mean patient age was 49.7 years. Mean follow-up was 48.8 months. Thirty-three, 40, 30, and 23 patients had stage I, II, III, and IVA disease, respectively. Mucoepidermoid carcinoma was the most common histologic type (34.7%), followed by acinic cell carcinoma (27.6%). Eighteen patients (18.4%) experienced recurrences (mean recurrence gap, 20.6 months; range, 2-87 months). Five- and 10-year disease-specific survival rates were 93.6% and 81.8%, respectively. In the univariate analysis, pathologic T stage, pathologic lymph node status, resection margin, external parenchymal extension, and maximum standardized uptake value were significantly associated with disease-specific survival. Pathologic lymph node status and maximum standardized uptake value were independent prognostic factors in the multivariate analysis. Our single-center experience with parotid gland cancer treatment is consistent with the literature. Cervical lymph node metastasis and high maximum standardized uptake value are associated with poor survival in parotid gland cancer. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    Knowledge of patients' in-session experiences that lead to symptom change in psychotherapy is limited. This study aims to investigate the within- and between-patient relationships between three in-session processes in psychotherapy (coping skills, therapeutic relationship quality, and emotional involvement) and symptom change on a session-by-session level. Participants (n = 1550) with various disorders, including primarily depression and anxiety, were treated with CBT in a German outpatient clinic. Symptom distress was assessed before each session and patients' in-session experiences were assessed at the end of each session using session reports. Person-mean centering was applied to disaggregate within- and between-patients. Within- and between-patient process scores were tested in multilevel models as predictors of next session symptom change. On a within-patient level, better session-specific coping skills, better therapeutic alliance, and deeper emotional involvement were followed by next session symptom improvements. In a combined model, only coping skills specifically predicted next session symptom change. Additionally, these coping skills were especially helpful when combined with a better therapeutic relationship quality. On a between-patient level, better therapeutic alliance and more coping skills were associated with lower symptom scores during treatment, while deeper emotional involvement was associated with higher symptom scores. Testing these between-patient effects in a combined model left only coping skills (the more, the greater symptom improvement) and emotional involvement (the deeper, the less symptom improvement) as significant predictors. These two also exhibited a combined effect on symptom change on the between-patient level. The results highlight the importance of a thorough disaggregation of within- and between-patient variability in psychotherapy process-outcome research as well as the consideration of several potentially important time

    The aim of this study is to determine the feasibility and efficacy of surgical management of single-segment lumbar spinal tuberculosis (TB) by using single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation. Seventeen cases of single-segment lumbar TB were treated with single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation. The mean follow-up was 36.9 months (range: 24-62 months). The kyphotic angle ranged from 15.2-35.1° preoperatively, with an average measurement of 27.8°. The American Spinal Injury Association (ASIA) score system was used to evaluate the neurological deficits and erythrocyte sedimentation rate (ESR) used to judge the activity of TB. Spinal TB was completely cured in all 17 patients. There was no recurrent TB infection. The postoperative kyphotic angle was 6.6-10.2°, 8.1° in average, and there was no significant loss of the correction at final follow-up. Solid fusion was achieved in all cases. Neurological condition in all patients was improved after surgery. Single-stage posterior transforaminal lumbar interbody fusion, debridement, limited decompression, 3-column reconstruction, and posterior instrumentation can be a feasible and effective method the in treatment of single-segment lumbar spinal TB.

    2011-01-01

    This literature review aimed to identify and assess the conservative treatment options for replacing a single missing anterior tooth, for patients who cannot afford implants or traditional bridges. The evidence was obtained using MEDLINE searches. A total of 19 studies met the inclusion criteria. None of these studies scored higher than 10 of 17, suggesting that all studies did not have strong evidence. Three of the studies examined resin-bonded bridges (RBBs), whereas the other three investigated removable partial dentures (RPDs). None of the studies had random patient selection. Three of these studies had controlled allocation of patients. The other three allowed new patients to enter the study throughout the study period. Placement of the prosthesis was only conducted in one study, whereas the rest of the studies examined patients with preexisting prostheses. In general, all 19 studies were weak due to poor study design, no acceptable controls, no direct comparison between RBBs and RPDs, lack of longitudinal studies and no differentiation between the anterior and posterior prostheses. Therefore, no definitive treatment conclusion can be made until studies of stronger design are conducted.

    Full Text Available The objectives here are to provide a systematic review of the current evidence concerning the use of Chinese herbs in the treatment of Alzheimer's disease (AD and to understand their mechanisms of action with respect to the pathophysiology of the disease. AD, characterized microscopically by deposition of amyloid plaques and formation of neurofibrillary tangles in the brain, has become the most common cause of senile dementia. The limitations of western medications have led us to explore herbal medicine. In particular, many Chinese herbs have demonstrated some interesting therapeutic properties. The following databases were searched from their inception: MEDLINE (PUBMED, ALT HEALTH WATCH (EBSCO, CINAH and Cochrane Central. Only single Chinese herbs are included. Two reviewers independently extracted the data and performed quality assessment. The quality assessment of a clinical trial is based on the Jadad criteria. Seven Chinese herbs and six randomized controlled clinical trials were identified under the predefined criteria. Ginkgo biloba, Huperzine A (Lycopodium serratum and Ginseng have been assessed for their clinical efficacy with limited favorable evidence. No serious adverse events were reported. Chinese herbs show promise in the treatment of AD in terms of their cognitive benefits and more importantly, their mechanisms of action that deal with the fundamental pathophysiology of the disease. However, the current evidence in support of their use is inconclusive or inadequate. Future research should place emphasis on herbs that can treat the root of the disease.

    Full Text Available Background. We examined overall and disease-free survivals in a cohort of patients subjected to resection of liver metastasis from colorectal cancer (CRLM in a 10-year period when new treatment strategies were implemented. Methods. Data from 239 consecutive patients selected for liver resection of CRLM during the period from 2002 to 2011 at a single center were used to estimate overall and disease-free survival. The results were assessed against new treatment strategies and established risk factors. Results. The 5-year cumulative overall and disease-free survivals were 46 and 24%. The overall survival was the same after reresection, independently of the number of prior resections and irrespectively of the location of the recurrent disease. The time intervals between each recurrence were similar (11 ± 1 months. Patients with high tumor load given neoadjuvant chemotherapy had comparable survival to those with less extensive disease without neoadjuvant chemotherapy. Positive resection margin or resectable extrahepatic disease did not affect overall survival. Conclusion. Our data support that one still, and perhaps to an even greater extent, should seek an aggressive therapeutic strategy to achieve resectable status for recurrent hepatic and extrahepatic metastases. The data should be viewed in the context of recent advances in the understanding of cancer biology and the metastatic process.

    Wastewater recycling has been and continues to be practiced all over the world for a variety of reasons including: increasing water availability, combating water shortages and drought, and supporting environmental and public health protection. Nowadays, one of the most interesting issues for wastewater recycling is the on-site treatment and reuse of grey water. During this study the efficiency of a compact Submerged Membrane Bioreactor (SMBR) system to treat real grey water in a single house in Crete, Greece, was examined. In the study, grey water was collected from a bathtub, shower and washing machine containing significant amounts of organic matter and pathogens. Chemical oxygen demand (COD) removal in the system was approximately 87%. Total suspended solids (TSS) were reduced from 95mgL(-1) in the influent to 8mgL(-1) in the effluent. The efficiency of the system to reduce anionic surfactants was about 80%. Fecal and total coliforms decreased significantly using the SMBR system due to rejection, by the membrane, used in the study. Overall, the SMBR treatment produces average effluent values that would satisfy international guidelines for indoor reuse applications such as toilet flushing. Copyright © 2016 Elsevier B.V.

    Full Text Available Biomechanical preparation of root canals with accentuated curvature is challenging. New rotatory systems, such as Reciproc, require a shorter period of time to prepare curved canals, and became a viable alternative for endodontic treatment of teeth with root dilaceration. Thus, this study aimed to report a clinical case of endodontic therapy of root with accentuated dilaceration using Reciproc single-file system. Mandibular right second molar was diagnosed as asymptomatic irreversible pulpitis. Pulp chamber access was performed, and glide path was created with #10 K-file (Dentsply Maillefer and PathFile #13, #16 and #19 (Dentsply Maillefer up to the temporary working length. The working length measured corresponded to 20 mm in the mesio-buccal and mesio-lingual canals, and 22 mm in the distal canal. The R25 file (VDW GmbH was used in all the canals for instrumentation and final preparation, followed by filling with Reciproc gutta-percha cones (VDW GmbH and AH Plus sealer (Dentsply Maillefer, using thermal compaction technique. The case has been receiving follow-up for 6 mon and no painful symptomatology or periapical lesions have been found. Despite the difficulties, the treatment could be performed in a shorter period of time than the conventional methods.

    This paper focuses on the targeting of single-walled carbon nanotubes (SWNTs) for the treatment of breast cancer with minimal side effects using photothermal therapy. The human protein annexin V (AV) binds specifically to anionic phospholipids expressed externally on the surface of tumour cells and endothelial cells that line the tumour vasculature. A 2 h incubation of the SWNT-AV conjugate with proliferating endothelial cells followed by washing and near-infrared (NIR) irradiation at a wavelength of 980 nm was enough to induce significant cell death; there was no significant cell death with irradiation or the conjugate alone. Administration of the same conjugate i.v. in BALB/c female mice with implanted 4T1 murine mammary at a dose of 0.8 mg SWNT kg −1 and followed one day later by NIR irradiation of the tumour at a wavelength of 980 nm led to complete disappearance of implanted 4T1 mouse mammary tumours for the majority of the animals by 11 days since the irradiation. The combination of the photothermal therapy with the immunoadjuvant cyclophosphamide resulted in increased survival. The in vivo results suggest the SWNT-AV/NIR treatment is a promising approach to treat breast cancer. (paper)

    Full Text Available Abstract Background Increasing evidence supports somato-visceral effects of manual therapies. We have previously demonstrated that a single spinal manipulative treatment (SMT accompanied by audible release has an inhibitory effect on the production of proinflammatory cytokines in asymptomatic subjects. The purpose of this study is to report on SMT-related changes in the production of the immunoregulatory cytokine interleukin 2 (IL-2 and to investigate whether such changes might differ with respect to the treatment approach related to the presence or absence of an audible release (joint cavitation. Methods Of 76 asymptomatic subjects, 29 received SMT with cavitation (SMT-C, 23 were treated with SMT without cavitation (SMT-NC and 24 comprised the venipuncture control (VC group. The SMT-C and SMT-NC subjects received a single, similar force high velocity low amplitude manipulation, in the upper thoracic spine. However, in SMT-NC subjects, positioning and line of drive were not conducive to cavitation. Blood and serum samples were obtained before and then at 20 and 120 min post-intervention. The production of IL-2 in peripheral blood mononuclear cell cultures was induced by activation for 48 hr with Staphylococcal protein A (SPA and, in parallel preparations, with the combination of phorbol ester (TPA and calcium ionophore. The levels of IL-2 in culture supernatants and serum were assessed by specific immunoassays. Results Compared with VC and their respective baselines, SPA-induced secretion of IL-2 increased significantly in cultures established from both SMT-C and SMT-NC subjects at 20 min post-intervention. At 2 hr post-treatment, significant elevation of IL-2 synthesis was still apparent in preparations from SMT-treated groups though it became somewhat attenuated in SMT-NC subjects. Conversely, IL-2 synthesis induced by TPA and calcium ionophore was unaltered by either type of SMT and was comparable to that in VC group at all time points. No

    Although the optimal treatment mode for medulloblastoma is frequently discussed, results based on large series of cases, especially those treated in Asia, have rarely been reported. Our purpose was to evaluate the efficacy of postoperative radiation therapy, and to identify prognostic factors, in a relatively large cohort of patients with limited-stage medulloblastoma treated at a single institute in China. Between January 1996 and April 2001, 69 patients with Chang stage M0/M1 medulloblastoma were referred to our hospital for radiation therapy after total or subtotal resection of the primary tumor. All patients received 30 Gy to the craniospinal axis followed by a 20-25 Gy boost to the posterior fossa (median fraction, 1.8 Gy). Sixty-four patients were followed for a median period of 38.5 months. The rates of 3-year and 5-year overall survival were 68.8% and 55.7%, respectively; corresponding disease-free survival were 57.8% and 51.4%, respectively. Patients who had received radiation treatment within 25 days after resection had a greater probability of 3-year survival (81.5% versus 59.5%; P=0.11) and 3-year disease-free survival (74.1% versus 46.0%; P=0.03) than patients who began radiation treatment later. No relationship was found between survival and age, sex or tumor size. This regimen was comparatively ineffective in preventing recurrence of postoperative medulloblastoma; however, we found that the interval between surgery and radiation is a significant prognostic factor for disease-free survival.

    School-based deworming is widely implemented in various countries to reduce the burden of soil-transmitted helminths (STHs), however, the frequency of drug administration varies in different settings. In this study, we compared the impact of a single annual treatment and 4-monthly treatment over a follow-up among Kenyan school children, and investigated the factors associated with residual infection. We performed a secondary analysis of data from a randomized trial investigating whether deworming for STHs alters risk of acquiring malaria. Children received either a single treatment or 4-monthly albendazole treatments were followed longitudinally from February 2014 to October 2014. The relative impact of treatment and factors associated with residual infections were investigated using mixed-effects regression models. Predisposition to infection was assessed based on Spearman's rank and Kendall's Tau correlation coefficients. In the 4-monthly treatment group, the proportion of children infected with hookworm decreased from 59.9 to 5.7%, while Ascaris lumbricoides infections dropped from 55.7 to 6.2%. In the single treatment group, hookworm infections decreased over the same time period from 58.7 to 18.3% (12.6% absolute difference in reduction, 95% CI: 8.9-16.3%), and A. lumbricoides from 56.7 to 23.3% (17.1% absolute difference in reduction, 95% CI: 13.1-21.1%). There was strong evidence for predisposition to both STH types. Residual hookworm infection among children on 4-monthly treatment were associated with male sex and baseline nutritional status, whereas A. lumbricoides infection was associated with individual and school-level infection at baseline, latrine cleanliness at schools. This study found that 4-monthly treatment w more effective than single annual treatment. Repeated treatments led to dramatic reductions in the intensities of STHs, but did not completely clear infections among school children in Kenya, a presumed reflection of reinfection in a setting

    Highlights: • We report the long-term results (2–4 years) with Flow Diverter Devices (FDD) from a single-center. • We recommend the use of FDD for large-neck aneurysms of the ICA syphon. • We think that more sophisticate FDD will reduce the incidence of technical adverse events. - Abstract: Objectives: Flow-Diverter Devices (FDD) are a new generation stents designed for the treatment of the intracranial aneurysms. This article reports the long-term results (2–4 years) of this treatment from a single-center. Methods: From November 2008 to January 2012, 35 patients (29 females and 6 males; mean age 53.9 y) with 39 intracranial aneurysms were treated by FDD. Five patients (14.3%) had ruptured aneurysms and 30 (85.7%) had no previous hemorrhage. The procedures were performed in 5 patients (14.3%) with SILK and in 30 (85.7%) with PED. In 3 patients FDDs were used as a second treatment after failure of previous coiling (2 cases) or stenting (one case). The 39 aneurysms were in supraclinoid ICA in 26 (66.7%), cavernous ICA in 2 (5.1%), PCoA in 4 (10.2%), MCA in 5 (12.9%), SCA in 1 (2.6%) and PICA in 1 (2.6%). The aneurysms were small (<10 mm) in 32 cases (82%), large (11–25 mm) in 6 (15.3%) and giant in 1 (2.6%). The occlusion rate according to the aneurysm location, size and neck and the complications were evaluated. Results: Peri-procedural complications included transient dysarthria (2 patients), vasospasm with acute intra-stent aggregation (one), microwire rupture (one) and failure of the stent opening (one). The follow-up was made between 24 and 62 months (mean 41 months); clinical examination and CTA were performed at 1, 3, 6 and 12 months after the procedure. The complete occlusion was confirmed by CTA and DSA. MRI with angiographic-studies was taken every year. Complete occlusion was obtained in 35 aneurysms (92.1%) and subtotal in 3 (7.9%). Complete occlusion occurred at 3 months in 24 cases (68.6%), within 3 and 6 months in 9 (25.7%). The rate and

    This paper aims to describe clinical and laboratory features and disease outcome in a single-centre cohort of patients with PFAPA syndrome (Periodic Fever, Aphtous stomatitis, Pharyngitis, and Adenitis) and to test performance of diagnostic and therapeutic algorithms. Patients fulfilling criteria were selected from the fever clinic population. Prospective follow-up together with recruitment of newly diagnosed patients followed pre-defined guidelines. Diagnostic and therapeutic algorithms and definitions of outcome and therapy response were formulated. Paired blood samples during febrile and afebrile periods were compared. Out of 176 patients referred for suspected periodic fever 125 children fulfilled criteria. Their age at onset was 23 months, median episode duration 3.5 days at 4-week intervals. Fever was associated with pharyngitis (91%), cervical adenitis (78%) and aphtae (41%). Among therapeutic options, episodic prednisone proved to be the most common first-line treatment. Administered to 77 patients, it reduced symptoms in 94%. Tonsillectomy led to the full symptom resolution in all 18 patients. Forty-six patients reached disease remission. Distribution of typical symptoms, response to therapies and disease outcome in a large patient cohort were documented. We offer diagnostic and therapeutic algorithms that have proven effective during this prospective trial. Our findings support the general belief of benign nature of this aetiologically unclear condition, despite proportion of patients having persistent disease for years. Maintenance of normal findings in afebrile intervals, striking response to a single dose of prednisone and normal growth and development together with spontaneous tendency towards prolongation of afebrile intervals are important confirmatory features of PFAPA syndrome.

    Intensity-modulated particle therapy (IMPT) for tumors showing interfraction motion is a topic of current research. The purpose of this work is to compare three treatment strategies for IMPT to determine potential advantages and disadvantages of ion prostate cancer therapy. Simulations for three treatment strategies, conventional one-plan radiotherapy (ConvRT), image-guided radiotherapy (IGRT), and online adaptive radiotherapy (ART) were performed employing a dataset of 10 prostate cancer patients with six CT scans taken at one week intervals. The simulation results, using a geometric margin concept (7-2 mm) as well as patient-specific internal target volume definitions for IMPT were analyzed by target coverage and exposure of critical structures on single fraction dose distributions. All strategies led to clinically acceptable target coverage in patients exhibiting small prostate motion (mean displacement < 4 mm), but IGRT and especially ART led to significant sparing of the rectum. In 20 % of the patients, prostate motion exceeded 4 mm causing insufficient target coverage for ConvRT (V95{sub mean} = 0.86, range 0.63-0.99) and IGRT (V95{sub mean} = 0.91, range 0.68-1.00), while ART maintained acceptable target coverage. IMPT of prostate cancer demands consideration of rectal sparing and adaptive treatment replanning for patients exhibiting large prostate motion. (orig.)

    Impaired fear memory extinction is widely considered a key mechanism of post-traumatic stress disorder (PTSD). Recent studies have suggested that neuroinflammation after a single prolonged stress (SPS) exposure may play a critical role in the impaired fear memory extinction. Studies have shown that high mobility group box chromosomal protein 1 (HMGB-1) is critically involved in neuroinflammation. However, the role of HMGB-1 underlying the development of impairment of fear memory extinction is still not known. Thus, we examined the levels of HMGB-1 in the basolateral amygdala (BLA) following SPS using Western blot and evaluated the levels of microglia and astrocytes activation in the BLA after SPS using immunohistochemical staining. We then examined the effects of pre-SPS intra-BLA administration of glycyrrhizin, an HMGB1 inhibitor, or LPS-RS, a competitive TLR4 antagonist, on subsequent post-SPS fear extinction. We found that SPS treatment prolonged the extinction of contextual fear memory after the SPS. The impairment of SPS-induced extinction of contextual fear memory was associated with increased HMGB1 and Toll-like receptor 4 (TLR4) levels in the BLA. Additionally, the impairment of SPS-induced extinction of contextual fear memory was associated with increased activation of microglia and astrocyte in the BLA. Intra-BLA administrations of glycyrrhizin (HMGB-1 inhibitor) or LPS-RS (TLR4 antagonist) can prevent the development of SPS-induced fear extinction impairment. Taken together, these results suggested that SPS treatment may not only produce short term effects on the HMGB1/TLR4-mediated pro-inflammation, but alter the response of microglia and astrocytes to the exposure to fear associated contextual stimuli. © 2018 The Author(s).

    Twenty-two patients with mild putaminal hemorrhage (neurological grades 1 and 2) were divided into three groups. Four (conservative group) received conservative treatment. Thirteen (aspiration group) underwent CT-guided stereotactic aspiration. Four (craniotomy group) underwent microsurgical evacuation of the hematoma. Surgical treatments were performed within 6 days after the onset. We measured the cerebral blood flow (CBF) using single-photon-emission CT and the [sup 133]Xe-inhalation method. The CBF was measured at the acute stage (Days 1-7), at the subacute stage (Days 8-14), and at the chronic stage (one month after the onset). In putaminal hemorrhage with both neurological grades 1 and 2 and with 2 only, the mean hemispheric CBF (mCBF) of the hematoma and the nonhematoma side among the three groups had no significance at any stage. In each group, no improvement in the reduction of mCBF was observed. In putaminal hemorrhage with neurological grade 1 only, however, the mCBF of the hematoma side at the chronic stage was 47.8[+-]6.7 ml/100 g/min in the conservative group and 59.1[+-]7.6 ml/100 g/min in the aspiration group. This difference was statistically significant. In the aspiration group, the mCBF values of both sides and the regional CBF (rCBF)-A[center dot]L[center dot]P at the chronic stage increased significantly compared with those at the acute and subacute stage. On the other hand, in the conservative group, no improvement in the reduction of CBF at the chronic stage was observed. From the serial measurement of CBF, it was observed that, compared with conservative therapy, CT-guited stereotactic aspiration for putaminal hemorrhage with neurological grade 1 is more effective.

    Most cases of idiopathic nephrotic syndrome in childhood are responsive to corticosteroids. However, there is a small group of children that demonstrate steroid resistance (steroid-resistant nephrotic syndrome; SRNS), steroid dependence, or that frequently relapse (frequent-relapse steroid-sensitive nephrotic syndrome; FR-SSNS) which are more clinically difficult to treat. Therefore, second-line immunosuppressants, such as alkylating agents, calcineurin inhibitors, antimetabolites and, more recently, rituximab, have been used with varying success. The objective was to evaluate the response rates of various second-line therapies in the treatment of childhood nephrotic syndrome. A retrospective chart review of pediatric subjects with idiopathic nephrotic syndrome was conducted at a single tertiary care center (2007-2012). Drug responses were classified as complete response, partial response, and no response. Of the 188 charts reviewed, 121 children were classified as SSNS and 67 children as SRNS; 58% were classified as FR-SSNS. Sixty-five subjects were diagnosed with focal segmental glomerulosclerosis via biopsy. Follow-up ranged from 6 months to 21 years. The combined rate of complete and partial response for mycophenolate mofetil (MMF) was 65% (33/51) in SSNS and 67% (6/9) in SRNS. For tacrolimus, the response rate was 96% (22/23) for SSNS and 77% (17/22) for SRNS. Eighty-three percent (5/6) of SSNS subjects treated with rituximab went into complete remission; 60% relapsed after B-cell repletion. Eight refractory subjects were treated with combined MMF/tacrolimus/corticosteroid therapy with a 75% response rate. Our experience demonstrates that older medications can be replaced with newer ones such as MMF, tacrolimus, and rituximab with good outcomes and better side effect profiles. The treatment of refractory cases with combination therapy is promising.

    The present study was comprised of 43 patients (16 men) with cervicogenic headaches for over three months, diagnosed according to the International Classification of Diagnostic Criteria of Headaches (ICDH-II). The patients were randomly assigned to receive either manual therapy for the cervical region (usual care group) or additional manual therapy techniques to the temporomandibular region to additionally influence temporomandibular disorders (TMD). All patients were assessed prior to treatment, after six sessions of treatment, and at a six-month follow-up. The outcome criteria were: intensity of headaches measured on a colored analog scale, the Neck Disability Index (Dutch version), the Conti Anamnestic Questionnaire, noise registration at the mandibular joint using a stethoscope, the Graded Chronic Pain Status (Dutch version), mandibular deviation, range of mouth opening, and pressure/pain threshold of the masticatory muscles. The results indicate in the studied sample of cervicogenic headache patients, 44.1% had TMD. The group that received additional temporomandibular manual therapy techniques showed significantly decreased headache intensities and increased neck function after the treatment period. These improvements persisted during the treatment-free period (follow-up) and were not observed in the usual care group. This trend was also reflected on the questionnaires and the clinical temporomandibular signs. Based on these observations, we strongly believe that treatment of the temporomandibular region has beneficial effects for patients with cervicogenic headaches, even in the long-term.

    Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes. The purpose of this systematic review was to compare the outcomes of tooth retention through endodontic microsurgery to tooth replacement using an implant supported single crown. Searches performed in PubMed, Cochrane Library, Web of Science, and EMBASE databases were enriched by citation mining. Inclusion criteria were defined. Sentinel articles were identified and included in the final selection of studies. Weighted survival and success rates for single implants and endodontic microsurgery were calculated. The quality of the articles reporting on single implants and endodontic microsurgery was moderate. Data for single implants were much more plentiful than for endodontic microsurgery, but the endodontic microsurgery studies had a slightly higher quality rating. Single implants and endodontic microsurgery were not directly compared in the literature. Outcomes criteria were often unclear. At 4-6 years, single implants had higher survival rates than teeth treated with endodontic microsurgery. Qualitatively different success criteria precluded valid comparison of success rates. Survival rates for single implants and endodontic microsurgery were both high (higher for single implants). Appraisal was limited by a lack of direct treatment comparisons. Long-term studies with a broad range of carefully defined outcomes criteria are needed. Copyright © 2015 American Association of Endodontists. Published by Elsevier Inc. All rights reserved.

    An effort is made to introduce thermodynamic and statistical thermodynamic methods into the treatment of nonphysical (e.g., social, economic, etc.) systems. Emphasis is placed on the use of the entire thermodynamic framework, not merely entropy. Entropy arises naturally, related in a simple manner to other measurables, but does not occupy a primary position in the theory. However, the maximum entropy formalism is a convenient procedure for deriving the thermodynamic analog framework in which undetermined multipliers are thermodynamic-like variables which summarize the collective behavior of the system. The authors discuss the analysis of Levine and his coworkers showing that the maximum entropy formalism is the unique algorithm for achieving consistent inference of probabilities. The thermodynamic-like formalism for treating a single lane of vehicular traffic is developed and applied to traffic in which the interaction between cars is chosen to be a particular form of the ''follow-the-leader'' type. The equation of state of the traffic, the distributions of velocity and headway, and the various thermodynamic-like parameters, e.g., temperature (collective sensitivity), pressure, etc. are determined for the example of the Holland Tunnel. Nearest-neighbor and pair correlation functions for the vehicles are also determined. Interesting and suggestive results are obtained

    Purpose: To assess the survival rate of female lung cancer treated at the Institute of Oncology of the Vilnius University, Lithuania during the period between 1996-2005. Materials and Methods: During the period between 1996-2005, 471 women diagnosed with lung cancer were treated at the Department of Thoracic Surgery and Oncology of the Institute of Oncology, Vilnius University. Data on morphology, stage and treatment was collected from the medical records. All lung cancer cases by histology were classified in two groups: non-small cell lung cancer (includes squamous cell carcinoma, large cell carcinoma, adenocarcinoma and other less common types) and small cell lung cancer. The vital status of the study group was assessed as of December 31, 2007, by passive follow-up, using data from the population registry. It was found that 411 (87.3%) of the patients had died. Survival was estimated according to the Kaplan-Meier method. Results: The median survival of female lung cancer diagnosed during 1996-2005 in Lithuania show to be 8.7 months (8.4 (95% CI 7.2-10.8) months with non-small cell lung cancer and 9.3 (95% CI 6.3-13.0) months with small-cell lung cancer). Survival was more than 20 months in resectable non-small cell lung cancer (stages I, II, IIIA). Non-small cell lung cancer survival in advanced stages was less than 7 months. Small-cell lung cancer patients median survival at limited and extended stages of the disease were 9.5 (95% CI 2.9-18.4) compared to 9.2 (95% CI 6.2-13.7) months. Non-small cell lung cancer patients most frequently were treated by surgery (27.0%), surgery and chemotherapy or radiotherapy (19.6%). Small cell lung cancer patient treatment included chemo and radiotherapy (27.0%), chemotherapy (19.0%), radiotherapy (17.5%), surgery (27.9%). Conclusions: The single center study of female lung cancer diagnosed during 1996-2005 in Lithuania show a significantly better chance of survival in resectable non-small cell lung cancer.

    A general introductory overview of the purpose of the group and the general subject area of SG tubing degradation was given by the facilitator. The purpose of the session was described as to open-quotes develop conclusions and proposals on regulatory and technical needs required to deal with the issues of SG tubing degradation.close quotes Types, locations and characteristics of tubing degradation in steam generators were briefly reviewed. The well-known synergistic effects of materials, environment, and stress and strain/strain rate, subsequently referred to by the acronym open-quotes MESSclose quotes by some of the group members, were noted. The element of time (i.e., evolution of these variables with time) was emphasized. It was also suggested that the group might want to consider the related topics of inspection capabilities, operational variables, degradation remedies, and validity of test data, and some background information in these areas was provided. The presentation given by Peter Millet during the Plenary Session was reviewed; Specifically, the chemical aspects and the degradation from the secondary side of the steam generator were noted. The main issues discussed during the October 1995 EPRI meeting on secondary side corrosion were reported, and a listing of the potential SG tube degradations was provided and discussed

The two-dose protocol was not superior to the single-dose protocol for the treatment of ectopic pregnancy. Although the two-dose methotrexate protocol for ectopic pregnancy was recently introduced to combine the efficacy and convenience of the fixed multi-dose and single-dose protocols, studies comparing the success rates, treatment satisfaction and acceptability of the single-dose and two-dose treatment protocols for ectopic pregnancy are currently lacking. A randomized trial was conducted on 92 participants with tubal ectopic pregnancy, between May 2013 and April 2015. Patients who were diagnosed with tubal ectopic pregnancy and who elected to undergo systemic methotrexate treatment were randomly assigned to follow either the single-dose (n = 46) or two-dose protocol (n = 46). The primary outcome measure was treatment success without surgical intervention. The secondary outcome measures were the incidence of methotrexate-associated side effects, β-human chorionic gonadotrophin (β-hCG) resolution time, cost of care received and treatment satisfaction. There were no differences in baseline characteristics between the groups. The success rates between the single-dose and two-dose groups did not show a significant difference [82.6 versus 87.0%; relative risk (RR) 0.95; 95% confidence interval (CI) 0.80-1.13]. However, the success rate in a subgroup of participants with a pretreatment β-hCG level of >5000 mIU/ml appeared to be higher in the two-dose group than in the single-dose group (80.0 versus 58.8%), although the difference was not statistically significant. No significant differences in methotrexate-associated side effects, cost or treatment satisfaction were observed between the groups. The two-dose group required a lower number of days for the β-hCG level to decrease to ectopic pregnancy. None. www

    Critical hand ischemia (CHI) can be devastating and may result in amputation. Distal vessel calcification has been shown to be a major factor in causing CHI. Atherectomy in the upper extremities is not typically considered due to the small anatomy; however, the Diamondback 360° Peripheral Orbital Atherectomy System (OAS) (Cardiovascular Systems, Inc.) can access treatment areas with a reference vessel diameter of 1.5mm. A retrospective, observational, single center (Merit Health Center, Jackson, MS) analysis of 11 CHI patients with calcific disease of the radial artery treated with orbital atherectomy (OAS) was completed. Demographics and procedural to 30-day outcomes were assessed. All patients had good blood flow to the hand after intervention and none experienced complications during or immediately post-procedure. At 30-days the freedom from revascularization and amputation was 100%, and all the wounds were healed. The following important principles were followed during the use of OAS for CHI: (1) ACT was therapeutic (~250s); (2) Gentle wire manipulation; (3) Utilization of a small OAS crown (1.25mm); (4) Aggressive vasodilator use-given through the exchange catheter; (5) Angioplasty balloon was matched to the size of the vessel and long and low pressure inflations were completed. Critical hand ischemia can be treated with endovascular techniques. Obtaining good outflow to the fingers is critical for wound healing and preventing amputation. Orbital atherectomy is a useful tool in preparing vessels for balloon angioplasty; particularly in cases where calcification is present. Copyright © 2016 The Authors. Published by Elsevier Inc.

    Guerra, J.; Tapping, R.L.

    1997-01-01

    This session was attended by delegates from 10 countries, and four papers were presented. A wide range of issues was tabled for discussion. Realizing that there was limited time available for more detailed discussion, three topics were chosen for the more detailed discussion: circumferential cracking, performance demonstration (to focus on POD and sizing), and limits of methods. Two other subsessions were organized: one dealt with some challenges related to the robustness of current inspection methods, especially with respect to leaving cracked tubes in service, and the other with developing a chart of current NDE technology with recommendations for future development. These three areas are summarized in turn, along with conclusions and/or recommendations. During the discussions there were four presentations. There were two (Canada, Japan) on eddy current probe developments, both of which addressed multiarray probes that would detect a range of flaws, one (Spain) on circumferential crack detection, and one (JRC, Petten) on the recent PISC III results

    The recycle stream from the DWPF constitutes a major source of water addition to the High Level Waste evaporator system. As now designed, the entire flow of 3.5 to 6.5 gal/min (at sign 25% and 75% attainment, respectively), or 2 gal/min during idling, flow to the 2H evaporator system (Tank 43). Substantial improvement in the HLW water balance and tank volume management is expected if the DWPF recycle to the HLW evaporator system can be significantly reduced. A task team has been appointed to study alternatives for reducing the flow to the HLW evaporator system and make recommendations for implementation and/or further study and evaluation. The brainstorming session detailed in this report was designed to produce the first cut options for the task team to further evaluate

    Full text: This number of the Bulletin appears during a month when the tenth regular session of the Agency's General Conference is being held. It is fitting that among the special arrangements made to give added significance to such an historical landmark should be an opening address by Herr Franz Jonas, Federal President of the host country, Austria. The Festsaal of the Kongresszentrum, in the Hofburg, has now been the centre for every annual session held in Austria, except the first. On that occasion, recorded in the photograph on the cover, the Konzerthaus was made available. A commemorative series of talks dealing with topics of particular interest in the international development of the peaceful uses of atomic energy, delivered by scientists of world distinction was another idea which will add much profound thought to the records of nuclear energy. Under the chairmanship of Professor L.C. Prado, with Dr. W.B. Lewis as Moderator, the subjects chosen by the participants were : The Impact of Atomic Energy in our Society - Sir John Cockcroft; Nuclear Power Systems and their Technical Potentialities - Prof. Alexandre Leipunski; The Commercial Future of Nuclear Power - Dr. William Webster; Nuclear Science in Life Sciences - Dr. A.R. Gopal-Ayengar; Fundamental Research in Atomic Energy Centres - Prof. Louis Neel. These speeches will be reproduced in full in the Agency's Atomic Energy Review. The pages of this issue of the Bulletin are intended to give indications of the stage which the Agency has now reached in some, but by no means all, of its activities in promoting the techniques of atomic energy for the benefit of mankind.

    The use of single-dose intramuscular administration of methotrexate in the treatment of ectopic pregnancies (EP) is a well-established practice. This study evaluates its use at a novel dose of 40 mg/m(2) body surface area (BSA). To evaluate the efficacy and safety of single-dose methotrexate treatment 40 mg/m(2) for tubal EP and persistent pregnancies of unknown location (PUL) and determine whether serum progesterone is a predictor of treatment success. Retrospective cohort study of patients receiving intramuscular methotrexate 40 mg/m(2) for the treatment of EP or PUL at Royal Prince Alfred Hospital over five years. One hundred and eighteen women received single-dose methotrexate with an overall success of 84%. Surgical intervention was needed in 16.6%. Pretreatment beta-hCG level and ectopic diagnosis were independent variables predictive of the need for surgery (P = 0.003 and 0.02, respectively). Serum progesterone level was not predictive of the need for a second dose or surgery. The sensitivity and specificity at pretreatment beta-hCG of 1202 IU/L were 84% and 74%, respectively. Commonly reported side effects included nausea, abdominal pain and heavy vaginal bleeding. Significant treatment-related adverse effects were rare. Single-dose IM methotrexate at a novel dose of 40 mg/m(2) is a safe and effective treatment for selected EP and persistent PUL. The risk of surgery was positively correlated to serum beta-hCG level and the diagnosis of EP. Progesterone was not a risk factor for surgery. Further studies are required to confirm the efficacy of this dose regimen and explore the safety of expectant management as an alternative to methotrexate treatment. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

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

    Full Text Available Objective: The objective of this study was to measure the effect of student-led educational events on geriatric patient and student participant perceptions in a community setting. Methods: Students led three events at a senior community center, focusing on learning and memory, sleep hygiene, and arthritis pain. The participants were geriatric patients who themselves were providers of support to homebound peers (“clients” through an independently organized program. Geriatric participants completed pre- and post-event surveys to measure changes in familiarity with the topics. Student participants also completed pre- and post-event surveys that tracked changes in their comfort in working with the geriatric population. Results: Each event demonstrated at least one positive finding for geriatric patients and/or their clients. Students reported increased comfort in working with and teaching the geriatric population following the first and third events, but not the second. Conclusion: Student-led educational sessions can improve perceived health-related knowledge of geriatric participants while simultaneously exposing students to the geriatric patient population. Overall, both students and geriatric participants benefited from these events. Practice Implications: Incorporation of single, student-led educational events could be mutually beneficial to students and the elderly population in the community and easily incorporated into any healthcare curriculum.

    Full Text Available Background: Nowadays, The first step in treatment of ectopic pregnancy (EP is medical treatment. Medical treatment with methotrexate (MTX for EP is safe and effective method without the risks associated with the surgical procedure. But there are controversies between studies for which patients will respond better to medical treatment. Objective: The aim of the present study was to investigate the predictive factors of success or failure of treatment of EP with single dose MTX. Materials and Methods: In this retrospective study, records of 370 patients who were treated for tubal EP with single dose of MTX were reviewed during four years. Patients were divided into two groups; the first group or “success group” are the patients who were successfully treated with MTX. The second group or “failure group” consist the patients who did not respond to the MTX therapy. The week of gestation, size and location of EP and β-hCG level were compared between groups. Results: Of 370 patients, 285 (77.1% were successfully treated with MTX. 85 patients (22.9% required surgery after a mean of 5.4 (range 2-15 days. Day-1 beta- human chorionic gonadotropin (β-hCG and fall in β-hCG between day 1 and day 4 were the best predictors for single dose MTX treatment success. The cutoff value of initial β-hCG with the success treatment results was found to be 1375 IU/mL there was no statistical difference between groups about week of gestation, size and location of EP. Conclusion: The results showed that patients who have β-hCG levels below 1375 and the number of cases with decreasing β-hCG level on day 4 are the good candidates for medical treatment.

    Passive acoustic treatments, also called liners, are the main solution to noise problems. The Single Degree Of Freedom (SDOF) acoustic treatment, composed of a thin material (perforated plate) affixed to air cavities with a rigid bottom, constitutes a solution. Predicting sound level reduction by an SDOF treatment requires reliable acoustic impedance models. An experimental/numerical method has been developed for a duct with an acoustic treatment to test acoustic impedance models of SDOF treatment with a multimodal propagation in the presence of a mean flow. This method is based on the comparison of experimental results from an aeroacoustic bench composed of a circular duct with a treated area, and numerical results from an FEM-PML axisymmetric model based on Galbrun's equation. The numerical results are confronted with experimental results to test impedance models up to M 0 =±0.25.

    Full Text Available Background. Endocrine Pancreatic Tumours (PENs are rare and can be nonfunctioning or functioning. They carry a good prognosis overall though high grade lesions show a relatively shorter survival. The aim of the current study is to describe a single centre analysis of the clinical characteristics and surgical treatment of PENs. Patients and Methods. This is a cohort analysis of 40 patients of PENs who underwent surgery at Sir Ganga Ram Hospital, New Delhi, India, from 1995 to 2013. Patient particulars, clinical features, surgical interventions, postoperative outcome, and followup were done and reviewed. The study group was divided based on grade (G1, G2, and G3 and functionality (nonfunctioning versus functioning for comparison. Results. PENs comprised 6.3% of all pancreatic neoplasms (40 of 634. Twenty-eight patients (70% had nonfunctioning tumours. Eighteen PENs (45% were carcinomas (G3, all of which were nonfunctioning. 14 (78% of these were located in the pancreatic head and uncinate process (P=0.09. The high grade (G3 lesions were significantly larger in size than the lower grade (G1 + G2 tumours (7.0 ± 3.5 cms versus 3.1 ± 1.6 cms, P=0.007. Pancreatoduodenectomy was performed in 18 (45%, distal pancreatectomy in 10 (25%, and local resection in 8 (20% and nonresective procedures were performed in 4 patients (10%. Fourteen patients (35% had postoperative complications. All G3 grade tumours which were resected had positive lymph nodes (100% and 10 had angioinvasion (71%. Eight neoplasms (20% were cystic, all being grade G3 carcinomas, while the rest were solid. The overall disease related mortality attributable to PEN was 14.3% (4 of 28 and for malignant PENs was 33.3% (4 of 12 after a mean follow-up period of 49.6 months (range: 2–137 months. Conclusion. Majority of PENs are nonfunctioning. They are more likely malignant if they are nonfunctioning and large in size, show cystic appearance, and are situated in the pancreatic head

    To evaluate the microshear bond strength (μSBS) of composite cement bonded to two machined glass ceramics and its durability, comparing conventional surface conditioning (hydrofluoric acid + silane) to a one-step primer (Monobond Etch & Prime). Machined slices of lithium disilicate ceramic (LDC) (IPS e.max CAD) and feldspathic ceramic (FC) (VITA Mark II) glass ceramics were divided into two groups (n = 10) according to two factors: 1. surface treatment: HF+S (ca 5% hydrofluoric acid [IPS Ceramic Etching GEL] + silane coupling agent [SIL; Monobond Plus]) or MEP (single-component ceramic conditioner; Monobond Etch & Prime); 2. storage condition: baseline (without aging; tested 24 h after cementing) or aged (70 days of water storage + 12,000 thermal cycles). Composite cement (Multilink Automix, Ivoclar Vivadent) was applied to starch matrices on the treated ceramic surfaces and photoactivated. A μSBS test was performed (0.5 mm/min) and the failure pattern was determined. Contact angle and micromorphological analyses were also performed. Data were analyzed with Student's t-test (α = 5%). For both ceramic materials, HF+S resulted in higher mean μSBS (MPa) at baseline (LDC: HF+S 21.2 ± 2.2 > MEP 10.4 ± 2.4; FC: HF+S 19.6 ± 4.3 > MEP 13.5 ± 5.4) and after aging (LDC: HF+S 14.64 ± 2.31 > MEP 9 ± 3.4; FC HF+S: 14.73 ± 3.33 > MEP 11.1 ± 3.3). HF+S resulted in a statistically significant decrease in mean μSBS after aging (p = 0.0001), while MEP yielded no significant reduction. The main failure type was adhesive between composite cement and ceramic. HF+S resuted in the lowest contact angle. Hydrofluoric acid + silane resulted in higher mean μSBS than Monobond Etch & Prime for both ceramics; however, Monobond Etch & Prime had stable bonding after aging.

    It is known that single-cell genomics is a powerful tool for accessing genetic information from uncultivated microorganisms. Methods of handling samples before single-cell genomic amplification may affect the quality of the genomes obtained. Using three bacterial strains we demonstrate that, compared to cryopreservation, lower-quality single-cell genomes are recovered when the sample is preserved in ethanol or if the sample undergoes fluorescence in situ hybridization, while sample preservation in paraformaldehyde renders it completely unsuitable for sequencing.

    Voinis, Sylvie

    2014-01-01

    The session addressed key issues related to the industrial feasibility of construction. It covered the implementer and regulator points of view. The conclusions derive from three presentations completed by the outcomes of six WG. At the Morsleben Repository, Germany, the licensing of the closure of the repository has been initiated by BfS. The closure concept is based on extensive backfilling with salt concrete complemented by seals. In order to demonstrate the feasibility of constructing such a seal structure an in-situ experiment is performed in a drift of the repository. In the UK, the framework for implementing geological disposal of the higher activity radioactive waste is described in the White Paper published by the UK Government in June 2008. The process to site a facility will be staged and based on voluntarism and partnership with local communities. This process is in its early stage. The paper outlines the work being undertaken by the NDA. In canada, Ontario Power Generation (OPG) has submitted information required for a CNSC licence to prepare the site and construct a DGR for the disposal of low and intermediate level waste from the operation of their nuclear power reactors. That submission includes an Environmental Impact Statement (EIS), as required for a Panel Review under the Canadian Environmental Assessment Act (CEAA), and the information required for a licence application under the NSCA Regulations. Discussions between the proponent and the regulator in the pre-licensing phase, clarified CNSC expectations for the characterization of the site and for the development of the EIS and application. They also helped to ensure that OPG understood these expectations. Outcomes WG session-1: - Start with construction but during operational phase: Simultaneous construction and operation activities. - Need for technical requirements/criteria: So that it can be judged whether 'products' meet the requirements; LT safety issues to be considered during

    The effect of microwave radiation on the luminescence properties of CdS and CdTe:Cl single crystals is studied. It is established that the exposure of these semiconductors to short-term (≤30 s) microwave radiation substantially modifies their impurity and defect structure. The mechanisms of transformation of the defect subsystem of II–VI single crystals upon microwave treatment are discussed. It is shown that the experimentally observed changes are defined by the nonthermal effects of microwave radiation at a power density of 7.5 W cm –2 ; at 90 W cm –2 , nonthermal effects are prevailing

  3. Synchrony in Dyadic Psychotherapy Sessions

    Science.gov (United States)

    Ramseyer, Fabian; Tschacher, Wolfgang

    Synchrony is a multi-faceted concept used in diverse domains such as physics, biology, and the social sciences. This chapter reviews some of the evidence of nonverbal synchrony in human communication, with a main focus on the role of synchrony in the psychotherapeutic setting. Nonverbal synchrony describes coordinated behavior of patient and therapist. Its association with empathy, rapport and the therapeutic relationship has been pointed out repeatedly, yet close evaluation of empirical studies suggests that the evidence remains inconclusive. Particularly in naturalistic studies, research with quantitative measures of synchrony is still lacking. We introduce a new empirical approach for the study of synchrony in psychotherapies under field conditions: Motion Energy Analysis (MEA). This is a video-based algorithm that quantifies the amount of movement in freely definable regions of interest. Our statistical analysis detects synchrony on a global level, irrespective of the specific body parts moving. Synchrony thus defined can be considered as a general measure of movement coordination between interacting individuals. Data from a sequence of N = 21 therapy sessions taken from one psychotherapy dyad shows a high positive relationship between synchrony and the therapeutic bond. Nonverbal synchrony can thus be considered a promising concept for research on the therapeutic alliance. Further areas of application are discussed.

    In this manuscript, we studied the difference in the treatment time required to execute a single-isocenter three-field irradiation of the head and neck, using either tray-mounted cerro-bend blocks or a multi-leaf collimator (MLC) for field shaping and automatic set-up. A total of twenty consecutive, unselected patients (16 males, four females), were eligible for this study because the dose they were to received was 44 Gy (2 Gy/fraction) to the head,neck and supraclavicular regions. Patients were randomly allocated to one of two treatment groups. The first group (n=11) was treated on a Philips SL-75 linear accelerator (SL-75), using 5 MV photons and tray-mounted cerro-bend blocks. The second group (n=9) was treated on a Philips SL-25 linear accelerator (SL-25-MLC), using 6 MV photons and a MLC. Patients of the second group were treated using the automatic set-up of the SL-25-MLC, without entering the treatment room between consecutive fields. Overall treatment time was significantly shorter on the SL-25-MLC than on the SL-75 (P<0.0001). The difference in total treatment-execution time was in the range of 157 s per treatment session. The largest difference was observed in the set-up time. There was an average of a 125 s time gain per treatment day (P<0.0001) in favour of the SL-25-MLC. Compared to tray-mounted cerro-bend blocks, a MLC and automatic set-up results in a significant time advantage when a single isocenter technique is used to treat head and neck cancer. (authors)

  5. Targeting single-walled carbon nanotubes for the treatment of breast cancer using photothermal therapy

    Neves, Luis Filipe Ferreira

    To develop a therapeutic system with cancer cell selectivity, the present study evaluated a possible specific and localized tumor treatment. Phosphatidylserine (PS) exposure on the external face of the cell membrane is almost completely exclusive to cancer cells and endothelial cells in the tumor vasculature. The human protein annexin V is known to have strong calcium-dependent binding to anionic phospholipids such as PS. This protein was studied for targeting single-walled carbon nanotubes (SWNTs) to the vasculature of breast tumors. The synthesis of the protein annexin V, by a pET vector in Escherichia coli, constitutes the first phase of this study. Recombinant annexin V was purified from the cell lysate supernatant by immobilized metal affinity chromatography. The overall production of purified annexin V protein was 50 mg/L. The binding ability of the protein annexin V was evaluated by determining the dissociation constant when incubated with proliferating human endothelial cells in vitro. The dissociation constant, Kd, was measured to be 0.8 nM, indicating relatively strong binding. This value of Kd is within the range reported in the literature. Single-walled carbon nanotubes (SWNTs) were functionalized with annexin V using two intermediate linkers (containing FMOC and DSPE) resulting in stable suspensions. The SWNT and protein concentrations were 202 mg/L and 515 mg/L, respectively, using the linker with DSPE (average of nine preparations). The conjugation method that used the DSPE-PEG-maleimide linker allowed to successfully conjugate the SWNTs with final concentrations approximately five times higher than the linker containing FMOC. The conjugation method used has a non-covalent nature, and therefore the optical properties of the nanotubes were preserved. The conjugate was also visually observed using atomic force microscopy (AFM), allowing to verify the presence of the protein annexin V on the surface of the nanotubes, with an height ranging between 2

    A comparison of treatment parameters and quality of clinical outcome in patients with single brain metastases treated with two different technologies for radiosurgery (Gamma Knife and CyberKnife). Treatment parameters were statistically analyzed. Clinical outcome was assessed by matched-pair analysis based on the treatment device, differences in dose prescription, and the date of the treatment. Patients were matched according to their tumor size, age, gender, primary cancer, and Radiation Therapy Oncology Group score. Survival post-radiosurgery, local and distant tumor control, and complications were analyzed. Predictive factors were investigated. 423 single brain metastases were treated with Gamma Knife and 73 with CyberKnife. Tumor volumes were similar. The parameters minimum tumor dose, maximum tumor dose, prescription isodose volume, conformality index, homogeneity index, volume of tissue receiving a dose of 10 Gy or more were significantly larger in Gamma Knife group. Sixty-three patients were good matches. These showed the same pattern in parameters. Concerning the outcome analysis, only overall survival differed significantly between groups, twice as long with CyberKnife (P new brain metastases, including whole brain radiation therapy. The most important result of this study was the finding that the obvious differences in treatment-related parameters between Gamma Knife and CyberKnife had no impact on the quality of the clinical outcome after radiosurgery. Survival time increased chronologically, presumably due to an intensified anti-cancer therapy in the more recent era of the CyberKnife treatments.

    The aim of this study was to compare single dose oral azithromycin versus seven-day doxycycline in the treatment of non-gonococcal mucopurulent cervicitis (MPC). One hundred and thirty-one women with non-gonococcal MPC were enrolled in a prospective-randomised study to compare the efficacy and safety of a single oral dose of 1 g azithromycin and a seven-day course of 100 mg doxycycline twice daily. Clinical examination and culture samples for Chlamydia trachomatis and other microorganisms were performed before and approximately 14 days after starting the treatment. Of the 131 women recruited (67 in the azithromycin group and 64 in the doxycycline group), Ureaplasma urealyticum was isolated from 21 (16%); Chlamydia trachomatis from 15 (11.5%); and Mycoplasma hominis from 3 (2.3%) of the patients at the initial examination. The eradication rate of baseline culture-positive cases at the follow-up visit in the azithromycin group was 71.4%, and 77.3% in the doxycycline group. There was no statistically significant difference in efficacy between the single dose azithromycin and seven-day course of doxycycline in the treatment of culture-positive cases. Azithromycin 1 g appears to be an effective and safe alternative to doxycycline for the treatment of non-gonococcal MPC.

    To compare the impact of a single fraction (8 Gy x 1 fraction) and multifraction (3 Gy x 10 fractions) radiotherapy regimens on pain relief, recalcification and the quality of life (QoL) in patients with bone destructions due to multiple myeloma (MM). In all, 101 patients were included in a randomised prospective clinical trial: 58 patients were included in the control arm (3 Gy x 10 fractions) and 43 patients into the experimental arm (8 Gy x 1 fraction). The response rate was defined according to the International Consensus on Palliative Radiotherapy criteria. Recalcification was evaluated with radiographs. QoL questionnaires were completed before and 4 weeks after treatment. Pain relief was obtained in 81/101 patients (80.2%): complete response in 56 (69%) and partial in 25 patients (30.9%). No significant differences were observed in analgesic response between the groups. Significant factors for pain relief were female gender, age under 65, IgG MM type, presence of recalcification at the irradiated site. Recalcification was found in 32/101 patients (33.7%): complete in 17 (53.2%) and partial in 15 (46.2%). No significant differences were observed in recalcification between the groups. Significant factors for recalcification were Karnofsky index ≥ 60%, haemoglobin level ≤ 80 g/dl, MM stage II and analgesic response at the irradiated site. The QoL after radiotherapy was improved in the control group. The same analgesic and recalcification response was observed using two different radiotherapy regimens. Higher doses should be used to achieve a better QoL. (orig.)

    Full Text Available Three types of post-weld heat treatment (PWHT, i.e. solution treatment + primary aging + secondary aging (I, secondary aging (II, and primary aging + secondary aging (III, were applied to a single crystal nickel-based superalloy joint made with linear friction welding (LFW. The results show that the grains in the thermomechanically affected zone (TMAZ coarsen seriously and the primary γ' phase in the TMAZ precipitates unevenly after PWHT I. The primary γ' phase in the TMAZ and weld zone (WZ precipitates insufficiently and fine granular secondary γ' phase is observed in the matrix after PWHT II. After PWHT III, the primary γ' phase precipitates more sufficiently and evenly compared to PWHTs I and II. Moreover, the grains in the TMAZ have not coarsened seriously and fine granular secondary γ' phase is not found after PWHT III. PWHT III seems more suitable to the LFWed single crystal nickel-based superalloy joints when performing PWHT.

    The advantages of reduced-port laparoscopic surgery (RPLS) for rectosigmoid cancer treatment have been disputed. This study evaluated the outcomes of RPLS compared to conventional laparoscopic surgery (CLS) for rectosigmoid cancer. Data from 211 patients who underwent a selective sigmoidectomy or anterior resection from August 2011 to June 2014 at a single institution were collected and analyzed via propensity score matching. Operative outcomes, inflammatory responses, pain intensity, oncologic outcomes, quality of life, and cosmetic results were compared between groups. After matching, 96 patients (48 CLS and 48 RPLS) were evaluated. Sixteen RPLS cases underwent single-incision laparoscopic surgery (SILS), and 32 underwent single-incision plus one port laparoscopic surgery (SILS + 1). Baseline clinical characteristics were comparable between the RPLS and the CLS groups. Morbidity, pathologic outcomes, and 3-year disease-free survival and overall survival rates were also comparable between the 2 groups. Compared with the CLS group, the RPLS group had a shorter total incision length (p time to liquid diet (p = 0.027), ambulation (p = 0.026), and discharge (p times, C-reactive protein levels at 24 h and 96 h, and interleukin-6 levels at 24 h postoperatively were significantly lower in the SILS + 1 group than those in the CLS and SILS groups (p cosmetic results, and both groups showed better results than the CLS group (p < 0.001). RPLS for rectosigmoid cancer is feasible, with short-term safety and long-term oncological safety comparable to that of CLS. Better cosmesis and accelerated recovery can be expected. SILS + 1 is a better choice than CLS or SILS for rectosigmoid cancer because it minimizes invasiveness and reduces technical difficulties.

    Abstract Purpose: To demonstrate that ultraviolet-A (UV-A) and voriconazole combination therapy is more effective than voriconazole single treatment for fungal keratitis. Methods: The in vitro UV-A (375 nm) fungicidal effect was evaluated on Fusarium solani solutions. Each fungal solution was irradiated with different UV-A irradiation doses. Also, a fungal solution containing voriconazole was also irradiated with UV-A. The in vivo therapeutic effect of UV-A and voriconazole treatment was studied in a rabbit keratitis model. Fungi were injected intrastromally into the cornea of 16 rabbits. Each treatment was initiated 3 days after fungal injection and continued up to 8 days for the following groups: Group 1, control; Group 2, treated with UV-A once a day; Group 3, treated with voriconazole 3 times a day; Group 4, treated with voriconazole 3 times a day and UV-A once a day. On the last day, the sclera–cornea buttons were extracted and microbiological and histological evaluations were performed. Results: The colony-forming units (CFUs) of fungal solutions in culture significantly decreased with UV-A irradiation. The CFUs of fungal solutions containing voriconazole also decreased with UV-A irradiation. In vivo, clinical scores of Group 3 (P=0.03) and Group 4 (P=0.02) 5 days after treatment were significantly lower compared to that of Group 1. The clinical score of Group 4 (P=0.03) 5 days after treatment was significantly lower compared to that of Group 3. The histopathological scores 5 days after treatment were significantly lower in Group 4 compared to those of Group 1 (Pvoriconazole combination treatment could be a safe and effective alternative to voriconazole single treatment for fungal keratitis.

    2015-01-01

    Full Text Available Background: Bone metastasis is a usual cause of pain in advanced cancer. Conventional radiation schedules require larger hospital stay and thus are not suitable for patients with poor general condition. This prospective observational study aims to compare the pain-relieving efficacy of different radiation fractionation schedules, i.e., 8 Gy administered in a single fraction versus 30 Gy administered in 10 fractions. Materials and Methods: Two hundred and fifty consecutive patients of bone metastasis were evaluated for the study, with 63 patients being excluded due to non-fulfillment of the inclusion criteria. The response to radiotherapy leading to pain relief as per the Visual Analog Scale was recorded at the end of treatment, 8 days, 15 days and 1 month during the follow-up visits. Results: Sixty-two percent of the patients received a single fraction while the remaining received 10 fractions. In the 10-fraction group, overall response was present in 60% of the patients. Stable pain was present in 23% of the patients while 9% patients had progressive pain. At 1 month of completion of treatment, 9% patients were lost to follow-up. In the single-fraction arm, overall response was seen in 58%, stable pain in 27% and progressive pain in 7% of the patients. Six percent of the patients were lost to follow-up. Conclusions: Single-fraction treatment for bony metastasis is as effective as multiple fractions to relieve bony pain and provides treatment convenience to both the patient and the caregiver.

    Nonadherence to treatment regimens for immunosuppressive agents is one of the major risk factors for allograft failure in kidney transplant recipients. The aim of this study was to estimate the relative effect of daily dosing on treatment adherence, not to identify how patients are non-adherent, in long-term kidney transplant recipients. In January 2009, a cross-sectional, anonymous, and voluntary questionnaire survey was given to kidney transplant recipients who regularly visited Inoue Hospital. A self-reporting questionnaire underestimates nonadherence, but we reasoned that the effect of the dosing regimen should be estimated with relative accuracy by using the generalized ordered logit/partial proportional hazard odds model given that the distribution patterns in the degree of nonadherence have been shown to be similar with other measures. Of 336 eligible patients, 312 (92.9 %) participated in this study. Two hundred seventy-four patients (87.8 %) were more than 3 years post-transplant. Univariate analysis revealed that a single daily dose was significantly associated with better adherence. After controlling for age, sex, time since transplantation, and the number of prescribed drugs, the effect of a single daily dose still remained significant [odds ratio, 0.40 (95 % confidence interval, 0.19-0.81); p = 0.011]. Several sensitivity analyses yielded similar results. To our knowledge, this is the first report that, in long-term kidney transplant recipients, a single daily regimen-one of few modifiable factors-might improve treatment adherence and allograft survival.

    methods are available to assess licensee safety culture, both formal (e.g. surveys, interviews) and informal (e.g. site inspector insights). - Regulatory staff should be given training to enable them to carry out safety culture interventions. - Regulators need to establish suitable internal regulatory processes and relationships to ensure effective sharing and use of safety culture information. - Current approaches to making a judgement on licensee safety culture are largely based on expert judgement, using data from a variety of sources. - There was general consensus that numerical rating of safety culture has limited meaning, especially a drive to a single number. - Building safety culture data collection into existing regulatory activities requires: commitment within the regulatory body, reflected in leadership, resources, and processes. - There was general agreement that interaction with licensees on safety culture issues should be not be fundamentally different to other regulatory areas. - To retain effective oversight of licensee safety culture it was agreed that regulators should provide an improved awareness of human and organizational factors/safety culture within the regulatory body, learn from other industries to avoid insularity, better integrate safety culture data collection into regulatory business, ensure long term follow up of issues and improve regulatory documentation. questions raised through the discussions as well as main points highlighted during the feedback session are listed

    Full Text Available OBJECTIVE: To investigate the secondary progressive multiple sclerosis (SPMS patients treated with mitoxantrone (MIT and discuss the effectiveness and side effects of MIT. METHODS: We retrospectively investigated 48 SPMS patients who completed or were still receiving MIT treatment. Expanded Disability Status Scale (EDSS scores of the patients were determined who had detailed examination before the treatment. Complete blood count, urine examination, chest x-ray, kidney and liver function tests, transthoracic echocardiography were performed at initiation and during follow-up and 10 mg/m2 MIT was administered every three months. The data were assessed in order to determine the effectiveness and side effects. RESULTS: A total of 48 patients, 34 women and 14 men, had an age of 42 (26-55 years at the initiation of MIT treatment. The duration of the treatment was 12 (3-30 months. The median EDSS scores were 6 (4-8 before the treatment and 6 (4-9 after the treatment. EDSS scores improved in 6 patients, deteriorated in 12 patients and 30 patients remained with stable EDSS scores during the treatment. Seventeen patients had no side effects however 31 patients developed side effects. CONCLUSION: On the basis of this study, which is a clinical assessment of the effectiveness and side effects of MIT, we conclude that MIT can limit disability in SPMS patients and it is useful in treating SPMS patients due to favorable risk-benefit ratio

    To determine if the metronidazole (MTZ) 2-gm single dose (recommended) is as effective as the 7-day 500 mg twice a day dose (alternative) for treatment of Trichomonas vaginalis (TV) among HIV+ women. Phase IV randomized clinical trial; HIV+ women with culture confirmed TV were randomized to treatment arm: MTZ 2-gm single dose or MTZ 500 mg twice a day 7-day dose. All women were given 2-gm MTZ doses to deliver to their sex partners. Women were recultured for TV at a test-of-cure (TOC) visit occurring 6-12 days after treatment completion. TV-negative women at TOC were again recultured at a 3-month visit. Repeat TV infection rates were compared between arms. Two hundred seventy HIV+/TV+ women were enrolled (mean age = 40 years, ±9.4; 92.2% African American). Treatment arms were similar with respect to age, race, CD4 count, viral load, antiretroviral therapy status, site, and loss-to-follow up. Women in the 7-day arm had lower repeat TV infection rates at TOC [8.5% (11 of 130) versus 16.8% (21 of 125) (relative risk: 0.50, 95% confidence interval = 0.25, 1.00; P TV among HIV+ women.

    One of the most direct means for human exposure to nanoparticles (NPs) released into the environment is drinking water. Therefore, it is critical to understand the occurrence and fate of NPs in drinking water systems. The objectives of this study were to develop rapid and reliable analytical methods and apply them to investigate the fate and transportation of NPs during drinking water treatments. Rapid single particle ICP-MS (SP-ICP-MS) methods were developed to characterize and quantify titanium-containing, titanium dioxide, silver, and gold NP concentration, size, size distribution, and dissolved metal element concentration in surface water and treated drinking water. The effectiveness of conventional drinking water treatments (including lime softening, alum coagulation, filtration, and disinfection) to remove NPs from surface water was evaluated using six-gang stirrer jar test simulations. The selected NPs were nearly completely (97 ± 3%) removed after lime softening and alum coagulation/activated carbon adsorption treatments. Additionally, source and drinking waters from three large drinking water treatment facilities utilizing similar treatments with the simulation test were collected and analyzed by the SP-ICP-MS methods. Ti-containing particles and dissolved Ti were present in the river water samples, but Ag and Au were not present. Treatments used at each drinking water treatment facility effectively removed over 93% of the Ti-containing particles and dissolved Ti from the source water. Copyright © 2015 Elsevier Ltd.

The data were analyzed with respect to obstetric characteristic, course of treatment, clinical, and reproductive outcomes. A total of 13 patients were evaluated. The median gestational age at diagnosis was 5 weeks 5 days (range: 4-9 weeks). The mean beta human chorionic gonadotrophin level was 11,240.31 ± 9812.68 IU/L (range: 2565-36,111 IU/L). All patients were successfully treated with systemic multidose MTX therapy. The average MTX dose was 5.7 (range: 2-9). The interval between the first MTX injection and the normalization of beta human chorionic gonadotrophin was 8 ± 2.27 weeks (range: 4-12 weeks). One patient showed mild leucopenia that reversed after the treatment. Three patients had successful uncomplicated intrauterine pregnancy after the treatment, which resulted in term infants. Systemic multidose MTX therapy is an effective and safe treatment method for CSP. However, further studies are needed to compare the safety, effectiveness and reproductive outcome of different treatment modalities in CSP. © 2014 The Authors.

    Four dimensional computed tomography (4DCT) scans are routinely used in radiation therapy to determine the internal treatment volume for targets that are moving (e.g. lung tumors). The use of these studies has allowed clinicians to create target volumes based upon the motion of the tumor during the imaging study. The purpose of this work is to determine if a target volume based on a single 4DCT scan at simulation is sufficient to capture thoracic motion. Phantom studies were performed to determine expected differences between volumes contoured on 4DCT scans and those on the evaluation CT scans (slow scans). Evaluation CT scans acquired during treatment of 11 patients were compared to the 4DCT scans used for treatment planning. The images were assessed to determine if the target remained within the target volume determined during the first 4DCT scan. A total of 55 slow scans were compared to the 11 planning 4DCT scans. Small differences were observed in phantom between the 4DCT volumes and the slow scan volumes, with a maximum of 2.9%, that can be attributed to minor differences in contouring and the ability of the 4DCT scan to adequately capture motion at the apex and base of the motion trajectory. Larger differences were observed in the patients studied, up to a maximum volume difference of 33.4%. These results demonstrate that a single 4DCT scan is not adequate to capture all thoracic motion throughout treatment.

    In consultation, school psychologists may offer educators direct training to support the implementation of classroom interventions aimed to improve student outcomes. The purpose of this study was to conduct a systematic literature review of single-case design research studies during which educators received direct training to implement a classroom intervention, specifically instructions, modeling, practice, and feedback. Two doctoral students in school psychology screened 228 articles and evaluated 33 studies to determine if direct training is effective and an evidence-based practice per single-case design standards proposed by the What Works Clearinghouse. Results of the review indicate that there is support for the practice to be deemed evidence-based and associated with better intervention implementation than before its application. Implications include direct training being considered for intensive, complex interventions to promote educator success with implementation.

    Purpose: The specific aim of this study was to evaluate outcome differences by gender and partner status for patients treated on Radiation Therapy Oncology Group (RTOG) protocol 97-14. Methods and Materials: RTOG 97-14 randomized patients with metastatic breast or prostate cancer to bone to receive 8 Gy in 1 fraction or 30 Gy in 10 fractions. Retreatment rates and overall survival were made based upon gender, marital status, and Karnofsky Performance Status (KPS). The cumulative incidence method was used to estimate retreatment time at 36 months from enrollment, and Gray's test was used to test for treatment differences within the same groupings. Marital status, gender, KPS, and treatment were variables tested in a univariate Cox model evaluating the time to retreatment. Results: Married men and women and single women receiving 30 Gy had significantly longer time to retreatment, p = 0.0067, p = 0.0052, and p = 0.0009 respectively. We failed to show a difference in retreatment rates over time in single men receiving either 30 Gy or 8 Gy. Univariate analysis of the entire group determined patients receiving 30 Gy in 10 fractions significantly less likely to receive retreatment, p < 0.0001, with a trend toward single patients less likely to be re-treated, p = 0.07. Conclusion: Non-disease-related variables, such as social support, might influence the results of clinical trials with subjective endpoints such as retreatment rates. The statistically nonsignificant difference in the 36-month retreatment rates observed in single male patients receiving 8 Gy may be a result of inadequate social support systems in place to facilitate additional care. Patients receiving 8 Gy in a single fraction had significantly higher retreatment rates compared with patients receiving 30 Gy in 10 fractions

    Surgical resection followed by radiotherapy and temozolomide in newly diagnosed glioblastoma can prolong survival, but it is not curative. For patients with disease progression after frontline therapy, there is no standard of care, although further surgery, chemotherapy, and radiotherapy may be used. Antiangiogenic therapies may be appropriate for treating glioblastomas because angiogenesis is critical to tumor growth. In a large, noncomparative phase II trial, bevacizumab was evaluated alone and with irinotecan in patients with recurrent glioblastoma; combination treatment was associated with an estimated 6-month progression-free survival (PFS) rate of 50.3%, a median overall survival of 8.9 months, and a response rate of 37.8%. Single-agent bevacizumab also exceeded the predetermined threshold of activity for salvage chemotherapy (6-month PFS rate, 15%), achieving a 6-month PFS rate of 42.6% (p < 0.0001). On the basis of these results and those from another phase II trial, the US Food and Drug Administration granted accelerated approval of single-agent bevacizumab for the treatment of glioblastoma that has progressed following prior therapy. Potential antiangiogenic agents-such as cilengitide and XL184-also show evidence of single-agent activity in recurrent glioblastoma. Moreover, the use of antiangiogenic agents with radiation at disease progression may improve the therapeutic ratio of single-modality approaches. Overall, these agents appear to be well tolerated, with adverse event profiles similar to those reported in studies of other solid tumors. Further research is needed to determine the role of antiangiogenic therapy in frontline treatment and to identify the optimal schedule and partnering agents for use in combination therapy

    High dose rate (HDR) brachytherapy treatment planning is conventionally performed manually and/or with aids of preplanned templates. In general, the standard of care would be elevated by conducting an automated process to improve treatment planning efficiency, eliminate human error, and reduce plan quality variations. Thus, our group is developing AutoBrachy, an automated HDR brachytherapy planning suite of modules used to augment a clinical treatment planning system. This paper describes our proof-of-concept module for vaginal cylinder HDR planning that has been fully developed. After a patient CT scan is acquired, the cylinder applicator is automatically segmented using image-processing techniques. The target CTV is generated based on physician-specified treatment depth and length. Locations of the dose calculation point, apex point and vaginal surface point, as well as the central applicator channel coordinates, and the corresponding dwell positions are determined according to their geometric relationship with the applicator and written to a structure file. Dwell times are computed through iterative quadratic optimization techniques. The planning information is then transferred to the treatment planning system through a DICOM-RT interface. The entire process was tested for nine patients. The AutoBrachy cylindrical applicator module was able to generate treatment plans for these cases with clinical grade quality. Computation times varied between 1 and 3 min on an Intel Xeon CPU E3-1226 v3 processor. All geometric components in the automated treatment plans were generated accurately. The applicator channel tip positions agreed with the manually identified positions with submillimeter deviations and the channel orientations between the plans agreed within less than 1 degree. The automatically generated plans obtained clinically acceptable quality.

  6. Using session types as an effect system

    Full Text Available Side effects are a core part of practical programming. However, they are often hard to reason about, particularly in a concurrent setting. We propose a foundation for reasoning about concurrent side effects using sessions. Primarily, we show that session types are expressive enough to encode an effect system for stateful processes. This is formalised via an effect-preserving encoding of a simple imperative language with an effect system into the pi-calculus with session primitives and session types (into which we encode effect specifications. This result goes towards showing a connection between the expressivity of session types and effect systems. We briefly discuss how the encoding could be extended and applied to reason about and control concurrent side effects.

    Low megavolt electron beam irradiation was used on 354 sites in 199 patients at Lahey Clinic either for palliation of symptomatic hypertrophic scars or as post operative irradiation in an attempt to prevent formation or recurrence of hypertrophic scars. Electron energies used ranged from 1.5 to 3.5 MeV. The median age of the 59 male patients was 22 years and of the 140 female patients 35 years. All patients had at least one follow-up visit, and the median follow-up was 35 months. Of the 294 sites treated for the first time, 272 (93 per cent) were irradiated with a single fraction with a skin dose ranging from 2 to 20 Gy. Of the 85 sites in 63 patients without excision of symptomatic hypertrophic scars, single-dose electron beam irradiation was of clinically significant value in only 41 sites (48 per cent). No patients have been treated without surgical excision since 1973. Because of a history of formation of hypertrophic scars elsewhere in the body, 13 patients with 19 incisions were treated prophylactically after operation for other diseases. All sites were irradiated with single doses ranging from 8 to 20 Gy, and hypertrophic scars did not subsequently develop in any patient. Altogether, 119 patients with 174 sites were irradiated after surgical excision of hypertrophic scars to prevent recurrence; 168 sites (97 per cent) received singe-fraction irradiation, and 161 received a dose of 8 Gy greater, up to 15 Gy. No statistically significant differences were observed in complete success rates, ranging from 82 to 90 per cent with doses of 9 Gy or greater. An interval of up to 72h between excision and single-fraction irradiation satisfactorily prevented recurrence, and clinically significant chronic telangiectasia was recorded in only one patient. Postoperative low megavolt electron beam irradiation with a single dose of 9 Gy or greater is highly effective in the prevention of formation recurrence of hypertrophic scars or keloids.

    Historically, treatments for cellulite have not been able to address all of its physiological components and require multiple sessions. The authors evaluate the safety and efficacy of a single, subdermal procedure to treat the underlying structure of cellulite. Fifty-seven patients underwent a 3-step cellulite treatment with a 1440-nm Nd:YAG laser with a side-firing fiber and temperature-sensing cannula. Efficacy was measured by the ability of blinded evaluators to distinguish baseline photos from those taken at 3 and 6 months posttreatment, as well as their rating of the results on a 5-point, 2-category ordinal photonumeric scale when comparing baseline photos to those taken at 2, 3, and 6 months posttreatment. Patient and physician satisfaction was assessed based on completion of a satisfaction survey at 2, 3, and 6 months posttreatment. Adverse events (AE) were recorded throughout the study. At 6 months posttreatment, blinded evaluators rated at least a 1-point improvement in the appearance of cellulite in 96% of treated sites. Blinded evaluators were also able to correctly identify baseline versus posttreatment photos in 95% of cases. At least 90% of patients and physicians reported satisfaction with the results of treatment throughout 6 months. AE were mild in intensity and transient to treatment. A single, 3-step, minimally invasive laser treatment using a 1440-nm Nd:YAG laser, side-firing fiber, and temperature-sensing cannula to treat the underlying structure of cellulite proved to be safe and maintained effectiveness at least 6 months posttreatment. 2.

  9. USING SESSION RPE TO MONITOR DIFFERENT METHODS OF RESISTANCE EXERCISE

    Full Text Available The purpose of this study was to compare session rating of perceived exertion for different resistance training techniques in the squat exercise. These techniques included traditional resistance training, super slow, and maximal power training. Fourteen college-age women (Mean ± SD; age = 22 ± 3 years; height = 1.68 ± 0. 07 m completed three experimental trials in a randomized crossover design. The traditional resistance training protocol consisted of 6 sets of 6 repetitions of squats using 80% of 1-RM. The super slow protocol consisted of 6 sets of 6 repetitions using 55% of 1-RM. The maximal power protocol consisted of 6 sets of 6 repetitions using 30% of 1-RM. Rating of perceived exertion (RPE measures were obtained following each set using Borg's CR-10 scale. In addition, a session RPE value was obtained 30 minutes following each exercise session. When comparing average RPE and session RPE, no significant difference was found. However, power training had significantly lower (p < 0.05 average and session RPE (4.50 ± 1.9 and 4.5 ± 2.1 compared to both super slow training (7.81 ± 1.75 and 7.43 ± 1.73 and traditional training (7.33 ± 1.52 and 7.13 ± 1.73. The results indicate that session RPE values are not significantly different from the more traditional methods of measuring RPE during exercise bouts. It does appear that the resistance training mode that is used results in differences in perceived exertion that does not relate directly to the loading that is used. Using session RPE provides practitioners with the same information about perceived exertion as the traditional RPE measures. Taking a single measure following a training session would appear to be much easier than using multiple measures of RPE throughout a resistance training workout. However, practitioners should also be aware that the RPE does not directly relate to the relative intensity used and appears to be dependent on the mode of resistance exercise that is used

    Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease. Most patients require long-term therapy with systemic steroids, and a steroid-sparing agent is usually also utilized. Dapsone is a chemotherapeutic agent with anti-inflammatory properties that is used as a steroid-sparing agent in PV. The aim of the present study was to evaluate the efficacy of dapsone as an adjuvant therapy in patients with PV. A retrospective analysis of patients' files was performed. All 26 patients included in the study group were treated with dapsone as an adjuvant to systemic steroids for at least 3 consecutive months and were followed up during their dapsone treatment period. After 3 months of treatment with dapsone, 13 patients were in the consolidation phase, 4 patients demonstrated partial remission on minimal therapy, 7 patients demonstrated complete remission on minimal therapy, and 2 patients were defined as treatment failures. The trend of clinical improvement continued after 6 months of treatment and at the study end point. This retrospective case series, one of the largest reported, indicates that dapsone is efficacious and safe for patients with PV in whom it is well tolerated soon after the initiation of treatment. © 2016 S.

    Methanogenic treatment of municipal solid waste (MSW) incineration leachate can be hindered by high concentrations of refractory organic matter and humification of compounds in the leachate. In an attempt to overcome some of these impediments, microbial electrolysis cells (MECs) were incorporated into anaerobic digesters (ADMECs). COD removal efficiencies and methane production were 8.7% and 44.3% higher in ADMECs than in controls, and ADMEC reactors recovered more readily from souring caused by high organic loading rates. The degradation rate of large macromolecules was substantially higher (96% vs 81%) in ADMEC than control effluent, suggesting that MECs stimulated degradation of refractory organic matter and reduced humification. Exoelectrogenic bacteria and microorganisms known to form syntrophic partnerships were enriched in ADMECs. These results show that ADMECs were more effective at treatment of MSW incineration leachate, and should be taken into consideration when designing future treatment facilities.

    Does repeat administration of misoprostol for early pregnancy loss increase the treatment success rate? Repeat administration of misoprostol does not increase the treatment success rate, and is associated with more analgesics use. Misoprostol reduces the need for surgical evacuation and shortens the time to complete expulsion in patients with early pregnancy loss. However, the impact of repeat doses of misoprostol is not clear. A randomized clinical trial was conducted in a single tertiary hospital, recruiting women with early pregnancy loss (misoprostol vaginally on Day 1, and were then randomly assigned into two groups: Patients in the single-dose group were evaluated on Day 8. Patients in the repeat-dose group were evaluated on Day 4, when they were given a repeat dose if required, and scheduled for re-evaluation on Day 8. If complete expulsion was not achieved on Day 8 (endometrial thickness >15 mm or the presence of gestational sac on transvaginal sonography), participants underwent surgical evacuation. The primary outcome was treatment success, defined as no need for surgical intervention up to Day 8. Final analysis included 87 participants in the single-dose group and 84 participants in the repeat-dose group, out of whom 41 (48.8%) received a second dose. Treatment succeeded in 67 (77%) patients in the single-dose group and 64 (76%) patients in the repeat-dose group (RR 0.98; 95% CI 0.83-1.16; P = 0.89). Patients in the repeat-dose group reported more use of over the counter analgesics (82.1% versus 69.0%, P = 0.04). The study was not blinded and our definition of complete expulsion may be debated. Follow-up time was not equal in all participants, since some had a complete expulsion on Day 4 and some underwent emergent D&C before Day 8. This, however, should not affect the primary outcome. Our results suggest that a single-dose protocol is superior to a repeat-dose protocol due to a comparable success rate and more favorable outcomes regarding the need for

    Uveal melanoma is a rare tumour with no established treatments once metastases develop. Although a variety of immune-based therapies have shown efficacy in metastatic cutaneous melanoma, their use in ocular variants has been disappointing. Recently, adoptive T-cell therapy has shown salvage responses in multiple refractory solid tumours. Thus, we sought to determine if adoptive transfer of autologous tumour-infiltrating lymphocytes (TILs) could mediate regression of metastatic uveal melanoma. In this ongoing single-centre, two-stage, phase 2, single-arm trial, patients (aged ≥16 years) with histologically confirmed metastatic ocular melanoma were enrolled. Key eligibility criteria were an Eastern Cooperative Oncology Group performance status of 0 or 1, progressive metastatic disease, and adequate haematological, renal, and hepatic function. Metastasectomies were done to procure tumour tissue to generate autologous TIL cultures, which then underwent large scale ex-vivo expansion. Patients were treated with lymphodepleting conditioning chemotherapy (intravenous cyclophosphamide [60 mg/kg] daily for 2 days followed by fludarabine [25 mg/m 2 ] daily for 5 days, followed by a single intravenous infusion of autologous TILs and high-dose interleukin-2 [720 000 IU/kg] every 8 h). The primary endpoint was objective tumour response in evaluable patients per protocol using Response to Evaluation Criteria in Solid Tumors, version 1.0. An interim analysis of this trial is reported here. The trial is registered at ClinicalTrials.gov, number NCT01814046. From the completed first stage and ongoing expansion stage of this trial, a total of 21 consecutive patients with metastatic uveal melanoma were enrolled between June 7, 2013, and Sept 9, 2016, and received TIL therapy. Seven (35%, 95% CI 16-59) of 20 evaluable patients had objective tumour regression. Among the responders, six patients achieved a partial response, two of which are ongoing and have not reached maximum

    To evaluate potential risk factors at admission for failed single-dose methotrexate injection in women with ectopic pregnancy. File review of a tertiary medical center in Israel yielded 102 consecutive patients with ectopic pregnancy initially treated with single-dose methotrexate. Overall successful treatment was defined as normalization of human chorionic gonadotropin (hCG) levels after the first or second injection. The mean pretreatment hCG level for the whole cohort was 2350 ± 2955 mIU/mL (median, 1187 mIU/mL; 90th percentile, 5000 mIU/mL). Resolution of ectopic pregnancy was achieved after a single injection in 76/102 (74.5%) women and after a second dose in 16/21 (76.2%) women. The remaining 10 (9.8%) patients were treated surgically after the first (5/76) or the second (5/26) dose. The overall success rate for methotrexate treatment was 90.2%. On multivariate stepwise logistic analysis, fetal cardiac activity was an independent predictor of a failed first methotrexate injection, and presence of a yolk sac and mass size were independent predictors of overall methotrexate failure and need for secondary surgery. In patients with ectopic pregnancy and relatively low levels of serum hCG, the most important predictors of overall failure of methotrexate injection were the presence of a yolk sac and mass size.

A single growth medium based on that of Reasoner et al. (1976) and consisting of 5.0 gr. proteose peptone, 3.0 gr. yeast extract, 10.0 gr. lactose, 7.5 gr. NaCl, 0.2 gr. sodium lauryl sulfate, and 0.1 gr. sodium desoxycholate per liter is used. The pH is adjusted to 6.5, and samples are incubated at 44.5 deg C. Bacterial growth is detected either by measuring the increase with time in the electrical impedance ratio between the innoculated sample vial and an uninnoculated reference vial or by visual examination for turbidity. Results obtained by the single-step method for chlorinated and unchlorinated effluent samples are in excellent agreement with those obtained by the standard method. It is suggested that in automated treatment plants impedance ratio data could be automatically matched by computer programs with the appropriate dilution factors and most probable number tables already in the computer memory, with the corresponding result displayed as fecal coliforms per 100 ml of effluent.

    Single-stage management of CBD stones comprises simultaneous common bile duct (CBD) clearance and cholecystectomy. The CBD can be cleared by using endoscopic treatment (ET) or laparoscopic surgery (LS) alone. To determine the most rapid recovery after the single-stage laparoscopic management of CBD stones. Patients with CBD stones treated at either of two centers (one performing ET only and one performing LS only for single-stage treatment) were included. The primary endpoint was "the textbook outcome". The feasibility rate was 74% for ET and 100% for LS (p≤0.001). The proportion of cases with the textbook outcome was higher in the ET group than in the LS-only group (73% vs. 10%; pCBD clearance rate was similar in the ET and LS-only groups (100% vs. 96.6%, respectively; p=0.17). The overall morbidity rate was lower in the ET group than in the LS-only group (23% vs. 29%, p=0.05). Both ET and LS are feasible, safe and effective for clearance of the CBD. ET was better than LS in terms of a less frequent requirement for drainage and a shorter length of hospital stay. LS was associated with a shorter operating time.

    Multiple clinical practice guidelines recommend rapid evaluation of patients with suspected lung cancer. It is uncertain whether delays in diagnosis and management have a negative effect on outcomes. This retrospective study included 551 patients diagnosed with lung cancer through the diagnostic assessment program at the Institut universitaire de cardiologie et de pneumologie de Québec between September 2013 and March 2015. Median wait times between initial referral, diagnosis, and first treatment were calculated and compared with recommended targets. Analyses were performed to evaluate for specific factors associated with longer wait times and for the effect of delays on the outcomes of progression-free survival (pfs), relapse-free survival (rfs) after primary surgical resection, and overall survival (os). Most patients were investigated and treated within recommended targets. Of the entire cohort, 379 patients were treated at our institution. Of those 379 patients, 311 (82%) were treated within recommended targets. In comparing patients within and outside target times, the only statistically significant difference was found in the distribution of treatment modalities: patients meeting targets were more likely to be treated with surgery or chemotherapy rather than with radiation. The pfs on first treatment modality was influenced by clinical stage, but not by time to therapy [hazard ratio (hr): 1.10; p = 0.65]. The os for the entire cohort was also influenced by stage, but not by delays (hr: 1.04; p = 0.87). For the 209 patients treated by surgery with curative intent, a significant reduction in rfs was associated with male sex and TNM stage, but not with delays (hr: 1.11; p = 0.83). The os after primary surgical resection was also associated with TNM stage, but not with delays (hr: 1.82; p = 0.43). Recommended targets for wait times in the investigation and treatment of lung cancer can be achieved within a diagnostic assessment program. Compared with radiation

    Nd:YAG laser has been used extensively for its versatility in treating many common aesthetic problems, but numerous adverse effects are often complained by recipients of Nd:YAG laser. This study introduces the ANT1 soybean extract cream, which was formulated to alleviate adverse effects after laser therapy. This study explores whether ANT1 enhances the repair mechanism of the postlaser skin, decreases laser-induced complication, and shortens recovery time. The study also aims to pinpoint the ANT1 concentration that is most effective in improving the skin condition after Nd-YAG laser therapy. This study was a single-center, randomized, double-blind, placebo-controlled trial. Patients eligible for the study were Asian women, aged 25 to 40 years, who were free of dermatological diseases and allergic reaction. There were a total of 45 subjects. Each subject received a session of Nd-YAG laser therapy every 2 weeks, totaling 3 sessions. Facial skin assessment was achieved via VISIA complexion analysis. VISIA complexion analysis quantitatively assessed the skin condition and tracked the recovery progress of each subject at baseline, immediately after all 3 laser sessions, and a week after the final laser treatment. Skin condition was evaluated by VISIA complexion analysis. Skin condition was recorded in aspects of pigmented spots, wrinkles, texture, pores, and red area. After Nd-YAG laser therapy, postlaser inflammation was observed in all subjects. Throughout the laser sessions and the outpatient follow-up clinic, the adverse effects of laser therapy, such as redness, spots, wrinkles, pores, and textures, decreased with the use of ANT1 cream. There has been a marked effect in wrinkle reduction in the patients who received a higher concentration of ANT1 cream (P ≤ 0.05). Statistically significant improvement in spots and pores is also seen (P ≤ 0.05). Through this study, the results suggest that the application of ANT1 soybean extract cream ameliorates the

    Full Text Available Objective: To determine the effects of yttrium-90 (Y-90 resin microsphere radioembolization therapy on patients with unresectable liver cancer who do not benefit from chemotherapy. Methods: Fifty-five patients underwent radioembolization therapy included in the study whose had unresectable primary or metastatic liver cancer originating from the gastrointestinal tract. Three were excluded from the study after pre-evaluation angiography. Thirteen (23.6% of the remaining 52 patients had hepatocellular carcinoma and 39 (76.4% had metastatic liver cancer. Fifty-two patients underwent Y-90 radioembolization treatment. Each patient's response to the administered treatment was evaluated using the Response Evaluation Criteria in Solid Tumors (RECIST and the overall probability of survival was displayed graphically by the Kaplan-Meier method. Results: After Y-90 therapy, 47 patients were follow-up. While 57% of the patients responded to treatment as clinical benefit, the disease progressed in 43%. The median hepatic progression-free survival time of the patients was 3.4 months (95% confidence interval (ci:1.4-5.3 and the overall survival time was 11.3 months (95%, CI:8.7-14.03. Conclusion: This study emphasizes that Y-90 resin microsphere radioembolization treatment is effective in patients with unresectable liver cancer.

    Full Text Available Background. Anemia, a common complication during treatment of malignant disease in children, was frequently treated with red blood cell transfusions. Several studies have shown, that the introduction of recombinant human erythropoietin (rh EPO for treating anemia in patients has been effective in reducing the need for transfusions. Variable doses of EPO from 150 to 900 IU/kg body weight have been used usually three times weekly. Recently some studies showed equally effective once weekly administration of EPO with proposed doses for children of 450 to 600 IU/ kg body weight.Efficacy and safety of once weekly EPO therapy was tested in 8/10 children treated in our Unit for solid tumors and nonHodgkin’s lymphoma. In this article we would like to present our one year experience with EPO treatment.Patients and methods. Patients have subcutaneously received the EPO dose of 600 UI/ kg body weight once weekly. Hemoglobin response and transfusion needs before and during treatment with EPO were analyzed.Results. Response was seen in 7/8 of patient, with increased hemoglobin level and lower transfusion needs. Only one patient was poor responder at first, but responded perfect after twice weekly EPO application. No adverse reaction related to EPO therapy was observed.Conclusions. Our experience with treating anemia in pediatric cancer patients who undergo intensive and aggressive chemotherapy treatment regimens are good and promising. Once weekly dosage regimen is child friendly and acceptable way of treating anemia.

    2016-06-01

    Full Text Available Heterotopic pregnancy refers to simultaneous presence of intrauterine and ectopic gestational sacs. Its incidence ex­hibits a rising trend due to the increased use of assisted reproductive technology (ART. This paper aims to present a rare case of tubal and cesarean scar heterotopic pregnancy that occurred following a spontaneous pregnancy. The pa­tient presenting with delayed menstruation and abdominal-inguinal pain was evaluated. Transvaginal ultrasonography revealed a gestational sac located in the scar of a previous cesarean section and in the left tubal region corresponding to a gestational age of 4 weeks and 5 days. The patient was hospitalized and informed about conservative and surgi­cal methods. Then, she was administered a single dose of methotrexate 75 mg intramuscularly. Post-operative period included ultrasonographic and laboratory follow-up. In conclusion, it should be remembered that single-dose systemic methotrexate therapy might constitute an alternative to surgery in unruptured hemodynamically stable cases.

  11. Reinfection of dogs with fish-borne zoonotic trematodes in northern Vietnam following a single treatment with praziquantel.

    Directory of Open Access Journals (Sweden)

    Sofie Nissen

    Full Text Available BACKGROUND: Fish-borne zoonotic trematodes (FZT infections including liver- and minute intestinal flukes are common in Southeast Asia in both humans and domestic animals eating raw fish and since 2010, the liver flukes are recognised as neglected tropical diseases by WHO. Mass drug treatment with praziquantel is advised for humans, but no recommendations for control of the FZT in the reservoir hosts exist. METHODOLOGY/PRINCIPAL FINDINGS: A study was conducted to assess the ability of praziquantel treatment for control of FZT in farm dogs in an endemic area in Northern Vietnam. Initially, 101 dogs from 73 households were examined for small trematode eggs in their faeces. Forty seven copro-positive dogs were included in the study. Thirty eight dogs received treatment with a single dose of 40 mg/kg of praziquantel. A group of nine dogs were left untreated. Coprological examination for small trematode eggs was performed on day 0, 3, 10, 30, 60, 90 and 120 post treatment. Farmers were questioned about dog keeping practises. All dogs were copro-negative for small trematode eggs on both day 3 and 10 post treatment. From day 30 onwards previously negative dogs became positive again. The reinfection rates were 26.3% (day 30, 45.5% (day 60, 53.1% (day 90, 61.3% (day 120.The nine untreated dogs remained positive throughout the study period. There was no difference in the intensity of infection at day 0 and 120 neither in the treated or untreated group. CONCLUSION: Dogs had easy access to raw fish and did not receive treatment against flukes by their owner. More than 50% of the dogs were reinfected 3 months post treatment. We do not recommend controlling FZT infections in dogs by anthelmintic treatment alone since reinfection occurs fast under the existing farm management systems.

    Effect of microwave radiation (24 GHz) on transformation of impurity-defect complexes in CdTe:Cl single crystals within the spectral range 1.3–1.5 eV was studied using the low-temperature (T=2 K) photoluminescence (PL) technique. The shapes of donor–acceptor pairs (DAP) and Y PL bands were studied in detail. The Huang–Rhys factor was calculated for the DAP luminescence depending on microwave radiation treatment. The increase of the distance between the DAP components responsible for emission at 1.455 eV and the quenching of Y-band due to microwave irradiation were observed. The method to decrease the amount of extended defects in near-surface layers of CdTe:Cl single crystals has been proposed.

    Many secure communication libraries used by distributed systems, such as SSL, TLS, and Kerberos, fail to make a clear distinction between the authentication, session, and communication layers. In this paper we introduce CEDAR, the secure communication library used by the Condor High Throughput Computing software, and present the advantages to a distributed computing system resulting from CEDAR's separation of these layers. Regardless of the authentication method used, CEDAR establishes a secure session key, which has the flexibility to be used for multiple capabilities. We demonstrate how a layered approach to security sessions can avoid round-trips and latency inherent in network authentication. The creation of a distinct session management layer allows for optimizations to improve scalability by way of delegating sessions to other components in the system. This session delegation creates a chain of trust that reduces the overhead of establishing secure connections and enables centralized enforcement of system-wide security policies. Additionally, secure channels based upon UDP datagrams are often overlooked by existing libraries; we show how CEDAR's structure accommodates this as well. As an example of the utility of this work, we show how the use of delegated security sessions and other techniques inherent in CEDAR's architecture enables US CMS to meet their scalability requirements in deploying Condor over large-scale, wide-area grid systems.

    Persons who stutter (PWS) should be referred to the most effective treatments available, locally or regionally. A prospective comparison of the effects of the most common stuttering treatments in Germany is not available. Therefore, a retrospective evaluation by clients of stuttering treatments was carried out. The five most common German stuttering treatments (231 single treatment cases) were rated as to their perceived effectiveness, using a structured questionnaire, by 88 PWS recruited through various sources. The participants had received between 1 and 7 treatments for stuttering. Two stuttering treatments (stuttering modification, fluency shaping) showed favorable and three treatments (breathing therapy, hypnosis, unspecified logopedic treatment) showed unsatisfactory effectiveness ratings. The effectiveness ratings of stuttering modification and fluency shaping did not differ significantly. The three other treatments were equally ineffective. The differences between the effective and ineffective treatments were of large effect sizes. The typical therapy biography begins in childhood with an unspecified logopedic treatment administered extensively in single and individual sessions. Available comparisons showed intensive or interval treatments to be superior to extensive treatments, and group treatments to be superior to single client treatments. The stuttering treatment most often prescribed in Germany, namely a weekly session of individual treatment by a speech-language pathologist, usually with an assorted package of mostly unknown components, is of limited effectiveness. Better effectiveness can be expected from fluency shaping or stuttering modification approaches, preferably with an intensive time schedule and with group sessions. Readers will be able to: (a) discuss the five most prevalent stuttering treatments in Germany; (b) summarize the effectiveness of these treatments; and (c) describe structural treatment components that seem to be preferable

    To describe the safety and efficacy of pegvisomant therapy and the predictors of treatment response in acromegaly patients at a single tertiary reference center in Brazil. We retrospectively reviewed the clinical, hormonal and radiological data of acromegaly patients treated with pegvisomant in our center. We also evaluated the presence of the d3 isoform of the growth hormone receptor (d3GHR). Twenty-seven patients were included (17 women). Pegvisomant was used in combination with octreotide LAR in 20 patients (74%), in combination with cabergoline in one (4%) and as monotherapy in six (22%). IGF-I normalization was achieved in 23 patients (85%). Mild and transitory elevation of liver enzymes was observed in two patients (7.4%), tumor growth in one (3.4%) and lipodystrophy in two (7.4%). One patient stopped the drug due to headaches. The GHR isoforms were evaluated in 14 patients, and the presence of at least one d3GHR allele was observed in 43% of them, but it was not a predictor of treatment response. Only pre-treatment IGF-I level was a predictor of treatment response. Pegvisomant treatment was highly effective and safe in our series of Brazilian patients. A better chance of disease control can be expected in those with lower pre-pegvisomant IGF-I levels.

    To investigate the effects of salpingectomy and methotrexate treatments on ovarian reserve in ectopic pregnancy. In this prospective study, a total of 131 patients with ectopic pregnancy were divided into 3 groups of methotrexate (MTX) only (Group-1, n: 55), salpingectomy only (Group-2, n: 61), and salpingectomy following MTX (Group-3, n: 15). Pretreatment and post-treatment anti-Müllerian hormone (AMH) levels were evaluated. Significant differences in AMH levels were detected between group 1 and group 2 (2.52±1.28 vs. 1.96±1.66, p=0.043), and group 1 and group 3 (2.52±1.28 vs. 1.77±0.76, p=0.035) at one month postoperative. However, these differences disappeared at the 3rd postoperative month. When AMH levels were compared within the same group, postoperative one month AMH levels were significantly lower than the preoperative AMH levels only in group 3 (p=0.03). However, this difference also disappeared at the 3rd postoperative month. Systemic single-dose methotrexate treatment, unilateral salpingectomy, and salpingectomy following methotrexate administration in ectopic pregnancy were reassuring based on pretreatment and post-treatment AMH levels. Current medical and surgical treatment approaches do not have an obvious negative effect on ovarian reserve. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Mortality up to 1 January 1983 has been studied in 14,106 patients with ankylosing spondylitis given a single course of X-ray treatment during 1935-54. For neoplasms other than leukaemia or colon cancer, mortality was 28% greater than that of members of the general population of England and Wales, and this increase is likely to have been a direct consequence of the treatment. The proportional increase reached a maximum of 71% between 10.0 and 12.4 years after irradiation and then declined. There were only a 7% increase in mortality from these tumours more than 25.0 years after irradiation and only for cancer of the oesophagus was the relative risk significantly raised in this period. Neither the magnitude of the relative risk, nor its temporal pattern following treatment, were greatly influenced by the age of the patient at first treatment. For leukaemia there was a threefold increase in mortality that is also likely to have been due to the radiotherapy. For colon cancer mortality was increased by 30%. For non-neoplastic conditions there was a 51% increase in mortality that was likely to be associated with the disease itself rather than its treatment. (author)

    Stereotactic radiosurgery/radiotherapy procedures are known to deliver a very high dose per fraction, and thus, the corresponding peripheral dose could be a limiting factor for the long term surviving patients. The aim of this clinical study was to measure the peripheral dose delivered to patients undergoing intracranial Cyberknife treatment, using the MOSFET dosimeters. The influence of the supplemental shielding, the number of monitor units and the collimator size to the peripheral dose were investigated. MOSFET dosimeters were placed in preselected anatomical regions of the patient undergoing Cyberknife treatment, namely the thyroid gland, the nipple, the umbilicus and the pubic symphysis. The mean peripheral doses before the supplemental shielding was added to the Cyberknife unit were 51.79 cGy, 13.31 cGy and 10.07 cGy while after the shielding upgrade they were 38.40 cGy, 10.94 cGy, and 8.69 cGy, in the thyroid gland, the umbilicus and the pubic symphysis, respectively. The increase of the collimator size corresponds to an increase of the PD and becomes less significant at larger distances, indicating that at these distances the PD is predominate due to the head leakage and collimator scatter. Weighting the effect of the number of monitor units and the collimator size can be effectively used during the optimization procedure in order to choose the most suitable treatment plan that will deliver the maximum dose to the tumor, while being compatible with the dose constraints for the surrounding organs at risk. Attention is required in defining the thyroid gland as a structure of avoidance in the treatment plan especially in patients with benign diseases

    Refractory epilepsies in children present a major burden for patients and their families. Cannabidiol (CBD) has been suggested as a potential treatment for refractory epilepsies. The aim of this study was to evaluate the effectiveness of add-on therapy with CBD for the treatment of refractory childhood epilepsies. Patients with childhood-onset refractory epilepsy, treated at the tertiary epilepsy center of the University Children's Hospital Ljubljana, Slovenia, were included in the study. Add-on therapy with CBD was initiated once the child's epilepsy was categorized as pharmacoresistant to other antiepileptic drugs/therapies. The dosage of CBD was gradually increased to at least 8mg/kg/day. The effect of CBD treatment was evaluated by the reduction in seizure burden and presence of side effects (positive and negative). Serial electroencephalography was performed in some children. Sixty-six patients were included in the analysis. Thirty-two (48.5%) patients had a more than 50% improvement regarding seizure burden, 14 of whom (21.2%) became seizure-free. None of the patients reported worsening of seizure frequency, but CBD had no effect in 15 (22.7%) patients. Some patients reported less vigorous seizures, shorter duration of seizures, shorter time to recovery, and other positive side effects of CBD treatment. Adverse effects were reported in 5/66 children. In our cohort of patients, CBD was found to have potential benefits as add-on therapy for refractory childhood epilepsies, mainly by reducing seizure burden. Copyright © 2018 Elsevier Inc.

    Full Text Available The aim of this study was to assess the analgesic effectiveness of three analgesic protocols in dogs undergoing a periodontal treatment. The study was performed as a prospective, randomized, “double blind” clinical study. A total of 45 client-owned dogs scheduled for periodontal treatment were included. Dogs of Group C received carprofen (4 mg·kg-1, dogs of Group B received bupivacaine (1 mg·kg-1 and dogs of Group CB received a combination of carprofen (4 mg·kg-1 and bupivacaine (1 mg·kg-1. Carprofen was administered subcutaneously 30 min before anaesthesia, bupivacaine was administered by nerve blocks in anaesthetized dogs. Painful periodontal treatment was performed in all patients, lasting up to one hour. Modified University of Melbourne Pain Score (UMPS, Visual Analogue Scale for pain assessment (VAS, plasma glucose and serum cortisol levels were assessed 30 min before administration of analgesics (C-0, B-0, CB‑0 and 2 h after recovery from anaesthesia (C-2, B-2, CB-2. For statistical analysis Friedman test, Mann-Whitney U-test, ANOVA and Fischer exact tests were used (P < 0.05. In CB‑2 compared to CB‑0 significantly decreased modified UMPS values. In CB‑2 UMPS values were significantly lower compared to C‑2 or B‑2. In C‑2 VAS values were significantly increased compared to C‑0, and in B‑2 VAS values were significantly increased compared to B‑0. Visual Analogue Scale values were significantly lower in CB‑2 compared to C‑2 or B‑2. Significantly increased plasma glucose concentrations were found in C‑2 compared to C‑0 and in B‑2 compared to B‑0. No other significant differences were detected. Administration of carprofen, bupivacaine or their combination is sufficient for early postoperative analgesia following periodontal treatment. Carprofen-bupivacaine combination is superior to carprofen or bupivacaine administered separately.

    Full Text Available Abstract Background Stereotactic radiosurgery/radiotherapy procedures are known to deliver a very high dose per fraction, and thus, the corresponding peripheral dose could be a limiting factor for the long term surviving patients. The aim of this clinical study was to measure the peripheral dose delivered to patients undergoing intracranial Cyberknife treatment, using the MOSFET dosimeters. The influence of the supplemental shielding, the number of monitor units and the collimator size to the peripheral dose were investigated. Methods MOSFET dosimeters were placed in preselected anatomical regions of the patient undergoing Cyberknife treatment, namely the thyroid gland, the nipple, the umbilicus and the pubic symphysis. Results The mean peripheral doses before the supplemental shielding was added to the Cyberknife unit were 51.79 cGy, 13.31 cGy and 10.07 cGy while after the shielding upgrade they were 38.40 cGy, 10.94 cGy, and 8.69 cGy, in the thyroid gland, the umbilicus and the pubic symphysis, respectively. The increase of the collimator size corresponds to an increase of the PD and becomes less significant at larger distances, indicating that at these distances the PD is predominate due to the head leakage and collimator scatter. Conclusion Weighting the effect of the number of monitor units and the collimator size can be effectively used during the optimization procedure in order to choose the most suitable treatment plan that will deliver the maximum dose to the tumor, while being compatible with the dose constraints for the surrounding organs at risk. Attention is required in defining the thyroid gland as a structure of avoidance in the treatment plan especially in patients with benign diseases.

    Endoscopic mucosal resection (EMR) has emerged for evaluation and treatment of esophageal nodules. We report our initial experience with EMR for T staging and management of early esophageal cancer. We reviewed patients undergoing EMR for esophageal adenocarcinoma between 2008 and 2013. The primary outcome measure was needed for esophagectomy. Secondary outcomes included complete eradication of adenocarcinoma, recurrence or persistence of cancer, nodal status for those undergoing esophagectomy, and complications of endoscopic treatment. During the study period, 24 patients underwent EMR demonstrating carcinoma, and a grossly margin negative endoscopic resection was achieved in all cases. Ten patients (42 %) had evidence of submucosal invasion and were referred for esophagectomy. Patients with margin negative EMR (n = 10, 42 %) or positive radial margins (n = 4, 16 %) underwent endoscopic surveillance and treatment with radiofrequency ablation or repeat EMR as needed. Thirteen patients (93 %) with intramucosal cancer (IMC) have been successfully managed with ongoing endoscopic surveillance and treatment with a median follow-up of 15.5 months. One patient underwent esophagectomy due to recurrent IMC in the setting of long-segment multifocal high-grade dysplasia. There were no esophageal perforations, one patient developed a self-limited gastrointestinal hemorrhage following EMR, and one had an esophageal stricture following endoscopic management. IMC can be successfully managed endoscopically and thus esophagectomy is avoided in a significant proportion of patients. Endoscopic management may be utilized in the setting of complete resection or radial margin involvement without evidence of submucosal invasion. Close endoscopic follow-up is of paramount importance even in those with negative margins, because recurrent disease may occur following EMR in these patients.

    With improved survival of childhood cancer patients, the number of long-term cancer survivors is increasing. Some studies have assessed the long-term morbidity after childhood cancer treatment in the developing countries. This study was conducted to assess the spectrum of late effects of cancer treatment in paediatric cancer survivors. Evaluation of the first 300 patients who completed five years of follow up in the after treatment completion clinic was done. Details of primary diagnosis, treatment received and current clinical status were noted. The spectrum of late effects was ascertained by appropriate investigations. Haematological malignancies comprised 25 per cent of total cases. Most common primary diagnosis comprised acute lymphoblastic leukaemia, retinoblastoma and Hodgkin's lymphoma. The median age at evaluation and follow up was 14 and 8.5 yr, respectively. Twenty three per cent (69) of the survivors had a minimal disability (growth retardation or underweight), 13 per cent (39) had moderate disabilities needing medical attention (hepatitis B surface antigen positive, myocardial dysfunction, azoospermia and hypothyroidism), while two per cent had major/life-threatening disabilities (mental retardation, liver disease and mortality). Eleven patients relapsed on follow up, of those five patients expired. Two second malignancies were recorded during the period of follow up. Late effects were of concern; however, severe disability (Grade 3-5) was seen in only two per cent survivors. Lifelong follow up of childhood cancer survivors is required to assess cancer-related morbidity, occurrence of a secondary neoplasm, to facilitate timely diagnosis and to implement remedial or preventive interventions to optimize health outcomes. Awareness towards the existence of late effects of cancer therapy is required among parents, patients and health professionals.

    Endoscopic Interventional Treatment is of little trauma and less complications in the treatment of gastric schwannoma and leads to faster recovery and fewer days of hospitalization. This study was aimed to investigate the safety and efficacy of endoscopic interventional therapy for gastric schwannoma, including endoscopic submucosal excavation, non-laparoscopic-assisted endoscopic full-thickness resection, endoscopic tunneling submucosal resection, and so on. Six patients of gastric schwannoma diagnosed by pathology examination were retrospectively analyzed ranging from Oct 2011 to Feb 2014 at Shandong Provincial Hospital affiliated to Shandong University. Five of the six patients accepted endoscopic interventional therapy. Among the five patients, there were four males and one female, aged from 48 to 65 years old (the average age was 58 ± 6.4). The lesions located at the fundus, the fundus-cardia, gastric body or gastric antrum, respectively, with the diameters ranged from 8 to 25 millimeter (the average was 17.1 ± 7.8 mm). All the patients were performed endoscopic interventional therapy successfully. Among five patients, one patient was treated by endoscopic tunneling submucosal resection, two by endoscopic submucosal excavation, and the other two were given endoscopic full-thickness resection. Operation duration was about 43 to 83 minutes (the average was 57.6 ± 16.1 minutes). The mass were completely removed, with limited bleeding. During the operation, perforation and pneumoperitoneum occurred in two patients, who finally recovered by endoscopic and conservative treatment. No bleeding, inflammation or infection occurred in these patients. The average follow-up time was (7.4 ± 4.4) months. Neither recurrence nor metastasis was found during follow-up. Endoscopic interventional therapy is a safe and effective treatment for gastric schwannoma.

    Full Text Available Abstract Background Lung cancer is a malignant carcinoma which has the highest morbidity and mortality in Chinese population. Gefitinib, a tyrosine kinase (TK inhibitor of epidermal growth factor receptor (EGFR, displays anti-tumor activity. The present data regarding first-line treatment with single agent gefitinib against non-small-cell lung cancer (NSCLC in Chinese population are not sufficient. Purpose To assess the efficacy and toxicity of gefitinib in Chinese patients with advanced non-small-cell lung cancer (NSCLC, a study of single agent treatment with gefitinib in Chinese patients was conducted. Methods 45 patients with advanced NSCLC were treated with gefitinib (250 mg daily until the disease progression or intolerable toxicity. Results Among the 45 patients, 15 patients achieved partial response (PR, 17 patients experienced stable disease (SD, and 13 patients developed progression disease (PD. None of the patients achieved complete response (CR. The tumor response rate and disease control rate was 33% and 71.1%, respectively. Symptom remission rate was 72.5%, and median remission time was 8 days. Median overall survival and median progression-free survival was 15.3 months and 6.0 months, respectively. The main induced toxicities by gefitinib were skin rash and diarrhea (53.3% and 33.3%, respectively. The minor induced toxicities included dehydration and pruritus of skin (26.7% and 22.2%, respectively. In addition, hepatic toxicity and oral ulceration occurred in few patients (6.7% and 4.4%2, respectively. Conclusions Single agent treatment with gefitinib is effective and well tolerated in Chinese patients with advanced NSCLC.

    Renal cell carcinoma (RCC) is more common in renal transplant and dialysis patients than the general population. However, RCC in transplanted kidneys is rare, and treatment has previously consisted of nephrectomy with a return to dialysis. There has been recent interest in nephron-sparing procedures as a treatment option for RCC in allograft kidneys in an effort to retain allograft function. Four patients with RCC in allograft kidneys were treated with nephrectomy, partial nephrectomy, or radiofrequency ablation. All of the patients are without evidence of recurrence of RCC after treatment. We found nephron-sparing procedures to be reasonable initial options in managing incidental RCCs diagnosed in functioning allografts to maintain an improved quality of life and avoid immediate dialysis compared with radical nephrectomy of a functioning allograft. However, in non-functioning renal allografts, radical nephrectomy may allow for a higher chance of cure without the loss of transplant function. Consequently, radical nephrectomy should be utilized whenever the allograft is non-functioning and the patient's surgical risk is not prohibitive. © 2013 John Wiley & Sons A/S.

    Multiple sclerosis (MS) is a chronic inflammatory demyelinating and neurodegenerative disease of the central nervous system characterized by unpredictable and variable clinical course. Etiology of MS involves both genetic and environmental factors. New technologies identified genetic polymorphisms associated with MS susceptibility among which immunologically relevant genes are significantly overrepresented. Although individual genes contribute only a small part to MS susceptibility, they might be used as biomarkers, thus helping to identify accurate diagnosis, predict clinical disease course and response to therapy. This review focuses on recent progress in research on MS genetics with special emphasis on the possibility to use single nucleotide polymorphism of candidate genes as biomarkers of susceptibility to disease and response to therapy.

    To find the frequency of deformity correction, functional outcome and complications of single-stage vertebral column resection in patients with kyphotic deformity. The prospective case series was conducted at Hayatabad Medical Complex, Peshawar, and Aman Hospital, Peshawar, from January 2012 to December 2013, and comprised all patients who underwent single-stage posterior vertebral column resection. Only patients with severe rigid sharp deformity of different aetiology that required more than 40 degree correction and who had at least 3-month follow-up were included. Data was processed using SPSS 16. Of the total 18 patients, 11(61.1%) were male and 7(38.9%) were female, with an overall mean age of 28.7±13.6 years (range: 12-60 years). Among them, 8(44.4%) patients had congenital kyphosis, 5(27.8%) had posttraumatic origin, 4(22.2%) had post-tuberculous deformity, while 1(5.6%) had iatrogenic kyphosis. The apex of the deformity was in thoracic spine in 12(66.7%) patients, while in 6(33.3%) patients it was in the lumbar spine. The average pre- and post-operative Cobb's angle was 66.2±18.9 degrees and 18.8±12.8 degrees respectively. Mean correction of deformities was 47.3±13.3 degrees. The mean correction achieved in percentage terms was 73.5±8.6 per cent (range: 56-87%). There were no patients with post-operative deterioration of neurological status. Two (11%) patients underwent re-exploration of the wounds with wash and cultures due to wound discharge. Posterior vertebral column resection was found to be a very effective method of correction of severe kyphotic deformities in expert hands with acceptable morbidity.

    The incidence of vulvar cancer is increasing, but surgical treatment-the current standard of care-often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer. We did a single-centre prospective trial at the University of Leipzig's Cancer Center. Eligible patients were aged 18 years or older, had ontogenetic stage 1-3b histologically proven primary carcinoma of the vulva, and had not undergone previous surgical or radiotherapy treatment for vulvar cancer or any other major perineal or pelvic disease. In view of staged morphogenesis of the vulva from the cloacal membrane endoderm at Carnegie stage 11 to adulthood, we defined the tissue domains of tumour spread according to the theory of ontogenetic cancer fields. On the basis of ontogenetic staging, patients were treated locally with partial, total, or extended vulvar field resection; regionally with therapeutic inguinopelvic lymph node dissection; and anatomical reconstruction without adjuvant radiotherapy. The primary endpoints were recurrence-free survival, disease-specific survival, and early postoperative complications. Analysis of tumour spread and early postoperative surgical complications was done by intention to treat (ie, all patients were included), whereas outcome analyses were done per protocol. This ongoing trial is registered with the German Clinical Trials Register, number DRKS00013358. Between March 1, 2009, and June 8, 2017, 97 consecutive patients were included in the study, of whom 94 were treated per protocol with vulvar field resection, therapeutic inguinopelvic lymph node dissection, and anatomical

    One of the underestimated causes of chronic pelvic pain (CPP) in women may be pelvic congestion syndrome (PCS) that is defined as the presence of varicose of ovarian and pelvic veins associated with chronic pain in the region of the pelvis. This pain is present longer than 6 months and intensifies with prolonged standing, coitus and menstruation. The disease constitutes a diagnostic as well as therapeutic problem, thus posing a challenge for the clinician. Transcatheter ovarian vein embolization might be a safe and effective option for PCS treatment. The objective of this study was to evaluate the efficacy of ovarian vein embolization ovarian as a method of the PCS treatment. Between 2002-2012, 11 embolization procedures were performed in 10 women (age range: 34-43; median age 39) with the diagnosis of PCS. One patient underwent embolization procedure twice. In 1 case the combined therapy of endovascular embolization and surgical phlebectomy of vulvar varices was performed. There were no major intrainterventional complications. In all the patients (100%) a significant improvement in the clinical status was noted. The procedure improved the quality of life in the patients. Three women (30%) had a mild recurrence of the symptoms at mid-term follow-up. Among 8 women who had complained of dyspareunia prior to embolization 6 patients reported complete pain relief, in other 2 cases the pain subsided partially. There was a significant decrease in the severity of symptoms associated with hemorrhoids. We consider embolization of insufficient ovarian veins an effective and safe way of treatment in a well-selected group of patients with PCS.

    The present study examined the effect of natural antimicrobials: chitosan, oregano and their combination, on the shelf-life of modified atmosphere packaged chicken breast meat stored at 4°C. Treatments examined in the present study were the following: M (control samples stored under modified atmosphere packaging), M-O (samples treated with oregano oil 0.25% v/w, stored under MAP), M-CH (samples treated with chitosan 1.5% w/v, stored under MAP) and M-CH-O (treated with chitosan 1.5% w/v and oregano oil 0.25% v/w, stored under MAP). Treatment, M-CH-O, significantly affected mesophilic Total Plate Counts (TPC), lactic acid bacteria (LAB), Brochothrix thermosphacta, Enterobacteriaceae, Pseudomonas spp., and yeasts-moulds during the storage period. Lipid oxidation (as determined by MDA values) of control and treated chicken samples was in general low and below 0.5 mg MDA/kg, showing no oxidative rancidity during the storage period. Addition of chitosan to the chicken samples produced higher (P15 (M-CH and M-CH-O) days. Interestingly, chitosan (M-CH) or chitosan-oregano (M-CH-O) treated chicken samples were sensorially acceptable during the entire refrigerated storage period of 21 days. It is noteworthy that the presence of chitosan in M-CH and M-CH-O samples did not negatively influence the taste of chicken samples, with M-CH samples receiving a higher score (compared to M-CH-O), probably as a result of a distinct and "spicy" lemon taste of chitosan, that was well received by the panelists. Based primarily on sensory data (taste attribute) M-CH and M-O treatments extended the shelf-life of chicken fillets by 6 days, while M-CH-O treatment resulted in a product with a shelf-life of 14 days, maintaining acceptable sensory characteristics.

    Low lumbar osteoporotic vertebral collapse (OVC) has not been well documented compared with OVC of the thoracolumbar spine. The differences between low lumbar and thoracolumbar lesions should be studied to provide better treatment. The aim of this study was to clarify the clinical and imaging features as well as outcomes of low lumbar OVC and to discuss the appropriate surgical treatment. Thirty patients (10 men; 20 women; mean age 79.3 ± 4.7 years [range 70-88 years]) with low lumbar OVC affecting levels below L-3 underwent surgical treatment. The clinical symptoms, morphological features of affected vertebra, sagittal spinopelvic alignment, neurological status before and after surgery, and surgical procedures were reviewed at a mean follow-up period of 2.4 years. The main clinical symptom was radicular leg pain. Most patients had old compression fractures at the thoracolumbar level. The affected vertebra was flat-type and concave or H-shaped type, not wedge type as often found in thoracolumbar OVC. There were mismatches between pelvic incidence and lumbar lordosis on plain radiographs. On CT and MR images, foraminal stenosis was seen in 18 patients (60%) and canal stenosis in 24 patients (80%). Decompression with short fusion using a posterior approach was performed. Augmentations of vertebroplasty, posterolateral fusion, and posterior lumbar interbody fusion were performed based on the presence/absence of local kyphosis of lumbar spine, cleft formation, and/or intervertebral instability. Although the neurological and visual analog scale scores improved postoperatively, 8 patients (26.7%) developed postoperative complications mainly related to instrumentation failure. In patients with postoperative complications, lumbar spine bone mineral density was significantly low, but the spinopelvic alignment showed no correlation when compared with those without complications. The main types of low lumbar OVC were flat-type and concave type, which resulted in neurological

    Advances in endourology have significantly reduced indications of open surgery in the treatment of staghorn calculi. However, in our experience, open surgery is still the treatment of choice in some cases. This study presents the results of a series of selected patients and discusses the results in terms of efficacy and morbidity. A cohort of 26 patients underwent anatrophic nephrolithotomy by lombotomy to treat a complex staghorn calculus. The mean stone size was 68,5mm, 70% were complete staghorn calculi. The operative time was 100minutes. Blood loss was 225mL, with a postoperative transfusion rate of 15.4%. The hospital stay was 8.4 days. The stone free rate following the procedure was 92%. The creatinine clearance (MDRD) at 3 months was improved from 5.9mL/min/m(2) on average over the entire series. There are clearly still indications for open surgery in staghorn stones management, with good results in this contemporary series on both stone removal and nephronic preservation. Yet, it appears that this technique is no longer taught. 5. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Since not only malignant melanomas but also many kinds of human cancers, for example thyroid cancer and squamous cell carcinoma, synthesize their specific protein, much attention has been paid to the establishment of selective thermal neutron capture treatment of malignant melanoma as a prototype of such cancer cells. This paper presents 10 B chlorpromazine compounds and 10 B 1 -para-boronophenylalanine ( 10 B 1 -BPA) as tumor-seeking 10 B compounds which themselves possess selective affinity for the specific metabolic activity of the target cancer cells. An overview of the following studies on the effects of 10 B 1 -BPA in the thermal neutron capture treatment of melanoma is provided: 1) in vitro studies on specific enhanced melanoma cell killing effects of 10 B 1 -BPA; 2) in vivo studies on therapeutic effects of 10 B 1 -BPA using melanoma-bearing hamsters; and 3) preclinical therapeutic experiments using spontaneously occurring malignant melanoma in Duroc pig skin, including experiments in which melanoma was successfully cured.

In this study, we investigated the therapeutic effects of β-elemene (ELE treatment in patients with newly diagnosed GBM who received concomitant chemoradiotherapy and adjuvant chemotherapy with temozolomide. Our results indicated that compared with control, patients who received ELE showed significantly longer median progression-free survival (PFS (8 months vs 11 months; P<0.001 and overall survival (OS (18 months vs 21 months; P<0.001. Despite the O-6-methylguanine-DNA methyltransferase (MGMT promoter methylation status, ELE treatment could significantly prolong the PFS (P=0.038 and OS (P=0.016. In multivariate analysis, ELE was a significant prognostic factor for PFS (hazard ratio [HR], 0.34; 95% confidence interval [95% CI]: 0.15–0.62; P=0.011 and OS (HR, 0.31; 95% CI: 0.14–0.69; P=0.006. Furthermore, ELE could significantly reduce the hematologic toxicities induced by chemoradiotherapy. In conclusion, ELE might provide a survival benefit in patients with GBM. Further study for verification might be needed. Keywords: glioblastoma, chemoradiotherapy, temozolomide, β-elemene

    Paraclinoid aneurysms have been increasingly treated endovascularly. The natural history of these aneurysms has gradually been elucidated. The purpose of this study was to assess the safety and efficacy of endovascular treatment for these aneurysms. We performed a retrospective review of 377 patients with 400 paraclinoid aneurysms treated between January 2006 and December 2012. Their clinical records, endovascular reports, and radiologic and clinical outcomes were analyzed. Because aneurysms ≥7 mm are at higher risk of rupture, we classified aneurysms as small (<7 mm) or large (≥7 mm). Overall, 115 of the 400 aneurysms (28.8%) were large (≥7 mm). Thromboembolic complications were found significantly more often with large aneurysms than with small ones (7.4% vs 1.0%, P = .001). Hemorrhagic complications were found only with small aneurysms (0.7%). The 6-month morbidity rates were similar for small (1.0%) and large (0.8%) aneurysms. Immediate angiographic outcomes were similar (P = .37), whereas recurrences and retreatment occurred more frequently with large aneurysms (P = .001 and P = .007, respectively). Multivariate analysis showed that aneurysm size was the only independent predictor for recurrence (P = .005). Most recurrences (81%) were detected by scheduled angiography at 6 months. Aneurysm size influenced the type of complication (thromboembolic or hemorrhagic) and the recurrence rate. Given the approximately 1% annual rupture rate for aneurysms ≥7 mm, analysis of our data supports the rationale of using prophylactic endovascular treatment for unruptured paraclinoid aneurysms ≥7 mm. © 2016 by American Journal of Neuroradiology.

    To explore clinical changes following a novel manual mobilisation technique, 24 participants who experienced 'moderate' to 'severe' chronic low back pain were recruited from new patients attending a suburban osteopathy clinic. The intervention was a previously undescribed side-lying mobilisation technique targeting the lumbosacral spine (median of 6 treatment sessions). After 8 weeks reductions were shown in Oswestry Disability Index of 15 points (95% CI: 9.3, 22.7; p pain intensity, disability and function improved in most participants following treatment. Further investigation is indicated using more robust research designs to compare this approach with other treatment approaches and usual care for the treatment of chronic low back pain.

    The topics covered in the Relativistic Heavy Ion Sessions span four orders of magnitude in energy in the laboratory and a few more in theory. In the two years since the last Intersections conference, experiments in the field of very high energy heavy ion research have begun at CERN and Brookhaven. The prime motivation for these experiments is the possibility of forming quark matter. This paper is a review of the topics covered in the Relativistic Heavy Ion Sessions

    Various tyrosine kinase signalling pathways affect the development and progression of colorectal cancer (crc). In clinical trials, regorafenib has been associated with a survival benefit in metastatic crc (mcrc). We assessed the safety and efficacy of regorafenib in real-world patients. In a retrospective review of patients with mcrc treated with regorafenib at our institution from 2013 to 2015, patient demographics, treatment, and survival data were collected. Progression-free survival (pfs) and overall survival (os) were estimated using the Kaplan-Meier method. In total, 48 patients were offered regorafenib, and 35 (73%) started treatment. Of the patients who started regorafenib, 57% were men. Median age in the cohort was 61 years, and all patients had a performance status in the range 0-2. Time from diagnosis of mcrc to regorafenib treatment was more than 18 months in 71% of patients. Starting dose was 160 mg in 54% of the patients, 120 mg in 40%, and 80 mg in 6%. Dose reductions occurred in 34% of the patients, and interruptions, in 29%. Best response was progressive disease (60%) and stable disease (17%); response in the rest of the patients was unknown. The most common adverse events on regorafenib (any grade) were fatigue (57%), hyperbilirubinemia (43%), thrombocytopenia (37%), anorexia (31%), and hypertension (31%). The most common grade 3 or 4 adverse events were fatigue (29%), hypophosphatemia (17%), weight loss (11%), and hyperbilirubinemia (9%). Common reasons for discontinuing regorafenib included progressive disease (51%) and toxicity (26%). In patients treated with regorafenib, pfs was 2.4 months (95% confidence interval: 1.8 to 3.3 months) and os was 5.6 months (95% confidence interval: 3.7 to 8.9 months). No factors were associated with survival in univariate or multivariate analysis. In a real-world setting, regorafenib is associated with survival similar to that reported in the randomized controlled trials, but at the expense of toxicity leading

    Full Text Available Background: Vaginal candidiasis (VC is one of the most common fungal diseases. Candida albicans is the most common causative fungus and has been isolated from more than 80% of specimens obtained from women with VC. Ketoconazole is the first orally active antifungal, the dosage for VC is 200 mg twice daily for 5 days. Fluconazole is the newer oral antifungal, its dosage for VC is a single oral dose of 150 mg. Since fluconazole 150 mg is considerably expensive, a single dose of 100 mg ketoconazole and 40 mg fluconazole in combination has been tested for the treatment of VC. The results showed that from 11 women with confirmed VC, 1-2 weeks after drug administration, the mycological culture was negative in 8 women, positive in 1 woman, and 2 woman
