Repeated-dose pharmacokinetics of inhaled ciclesonide (CIC-HFA) in Japanese children with bronchial asthma: a phase I study.

BACKGROUND
Ciclesonide (CIC) is a highly safe, inhaled corticosteroid (ICS) that is converted into a pharmacologically active metabolite (des-isobutyryl-ciclesonide); this metabolite, in turn, exerts a local anti-inflammatory effect on lung tissue. The present study was undertaken to analyze the pharmacokinetics of des-isobutyryl-ciclesonide in the serum of Japanese children with bronchial asthma treated by repeated doses of CIC and to compare the data thus obtained with those obtained for Caucasian children with bronchial asthma.


METHODS
Eight Japanese children with bronchial asthma were treated for 7 days with CIC-hydrofluoroalkalane (CIC-HFA) 200 μg/day administered by a metered-dose inhaler. The study was designed to assess the pharmacokinetics after 7-day repeated administration by which the steady state can be achieved, based on the results of an earlier study involving healthy Japanese adult males who received 7-day repeated administration of CIC-HFA. Blood was sampled at multiple time points on Day 7 of treatment for measurement of the serum des-isobutyryl-ciclesonide level.


RESULTS
The pharmacokinetic parameters (AUC from time zero to last observed concentration [AUC(t)], AUC over the dosage interval τ at steady state [AUC(ss)], maximum concentration [C(max)], and terminal elimination half-life [T(1/2)]) and the temporal changes in the serum levels of des-isobutyryl-ciclesonide after repeated administration of CIC-HFA (200 μg/day) in Japanese children with bronchial asthma differed only slightly from those in Caucasian children with bronchial asthma. No serious adverse events were noted during the study period. Additionally, no abnormalities were detected in the serum cortisol level, other laboratory parameters, or vital signs.


CONCLUSIONS
Our results suggest that there is little difference in the pharmacokinetics of des-isobutyryl-ciclesonide up on repeated administration of CIC-HFA between Japanese and Caucasian children with bronchial asthma. And our study suggests that CIC-HFA (200 μg/day, once daily) can be administered safely for 7 days, without raising any safety concerns.
Vaginal orgasm is associated with less use of immature psychological defense mechanisms.

INTRODUCTION
Freud implied a link between inability to have a vaginal orgasm and psychosexual immaturity. Since Kinsey, many sexologists have asserted that no such link exists. However, empirical testing of the issue has been lacking.


AIM
The objective was to determine the relationship between different sexual behavior triggers of female orgasm and use of immature psychological defense mechanisms.


METHODS
Women reported their past month frequency of different sexual behaviors and corresponding orgasm rates and completed the Defense Style Questionnaire (DSQ-40).


MAIN OUTCOME MEASURE
The association between ability to have vaginal intercourse orgasm (versus clitoral orgasm) and the use of DSQ-40 immature psychological defense mechanisms (associated with various psychopathologies) was examined.


RESULTS
In a sample of 94 healthy Portuguese women, vaginal orgasm (triggered solely by penile-vaginal intercourse) was associated with less use of DSQ-40 immature defenses. Vaginal orgasm was associated with less somatization, dissociation, displacement, autistic fantasy, devaluation, and isolation of affect. Orgasm from clitoral stimulation or combined clitoral-intercourse stimulation was not associated with less use of immature defenses, and was associated with more use of some immature defenses. In one regression analysis, more masturbation and less vaginal orgasm consistency made independent contributions to the statistical prediction of immature defenses. In another regression analysis, any use of extrinsic clitoral stimulation for intercourse orgasm, and lack of any vaginal orgasm, made independent contributions to the statistical prediction of immature defenses. Vaginally anorgasmic women had immature defenses scores comparable to those of established (depression, social anxiety disorder, panic disorder, and obsessive-compulsive disorder) outpatient psychiatric groups. Results were not confounded by social desirability responding or relationship quality.


CONCLUSIONS
The results linking penile-vaginal orgasm with less use of immature psychological defense mechanisms are consistent with both early psychoanalytic personality theory and recent advances in sexual physiology. Implications for diagnosis and sex therapy are noted.
A randomized, double-blind, placebo-controlled study of light therapy for antepartum depression.

OBJECTIVE
Affective disorder during pregnancy is a common condition requiring careful judgment to treat the depression while minimizing risk to the fetus. Following up on promising pilot trials, we studied the efficacy of light therapy.


METHOD
Twenty-seven pregnant women with nonseasonal major depressive disorder according to DSM-IV (outpatients, university polyclinic) were randomly assigned to 7,000 lux fluorescent bright white or 70 lux dim red (placebo) light administered at home in the morning upon awakening for 1 h/d in a 5-week double-blind trial carried out between October 2004 and October 2008. Clinical state was monitored weekly with the 29-item Structured Interview Guide for the Hamilton Depression Rating Scale (HDRS) with Atypical Depression Supplement (SIGH-ADS). Changes of rating scale scores over time were analyzed with the general linear model. Differences from baseline of SIGH-ADS and 17-item HDRS scores at every time point were the dependent variables, time was the within-subjects factor, and treatment was the between-subjects factor. The model also included baseline score of depression and gestational age at intervention start.


RESULTS
The superiority of bright light over dim light placebo was shown for both SIGH-ADS (R² = 0.251; F(3,23) = 3.91; P < .05) and HDRS (R² = 0.338; F(3,23) = 5.42; P < .01) when analyzing the week-by-week change from baseline, and HDRS scores showed a significant interaction of treatment with time (F(4,92) = 2.91; P < .05). Categorical analysis revealed that the response rate (HDRS ≥ 50% improvement) at week 5 was significantly greater for bright light (81.3%, n = 16) than for placebo light (45.5%, n = 11) (P < .05). Remission (final score ≤ 8) was attained by 68.6% versus 36.4%, respectively (P < .05). Expectation ratings did not differ significantly between groups.


CONCLUSIONS
Bright white light treatment for 5 weeks improved depression during pregnancy significantly more than placebo dim red light. The study provides evidence that light therapy, a simple, cost-effective antidepressant modality with minimal side effects for the mother and no known risk for the unborn child, may be a useful nonpharmacologic approach in this difficult situation.

Fast Image Inpainting Based on Coherence Transport

High-quality image inpainting methods based on nonlinear higher-order partial differential equations have been developed in the last few years. These methods are iterative by nature, with a time variable serving as iteration parameter. For reasons of stability a large number of iterations can be needed which results in a computational complexity that is often too large for interactive image manipulation. Based on a detailed analysis of stationary first order transport equations the current paper develops a fast noniterative method for image inpainting. It traverses the inpainting domain by the fast marching method just once while transporting, along the way, image values in a coherence direction robustly estimated by means of the structure tensor. Depending on a measure of coherence strength the method switches continuously between diffusion and directional transport. It satisfies a comparison principle. Experiments with the inpainting of gray tone and color images show that the novel algorithm meets the high level of quality of the methods of Bertalmio et al. (SIG-GRAPH ’00: Proc. 27th Conf. on Computer Graphics and Interactive Techniques, New Orleans, ACM Press/Addison-Wesley, New York, pp. 417–424, 2000), Masnou (IEEE Trans. Image Process. 11(2):68–76, 2002), and Tschumperlé (Int. J. Comput. Vis. 68(1):65–82, 2006), while being faster by at least an order of magnitude.
Adverse health effects of marijuana use.

Copyright © 2014 Massachusetts Medical Society. In light of the rapidly shifting landscape regarding the legalization of marijuana for medical and recreational purposes, patients may be more likely to ask physicians about its potential adverse and beneficial effects on health. The popular notion seems to be that marijuana is a harmless pleasure, access to which should not be regulated or considered illegal. Currently, marijuana is the most commonly used “illicit” drug in the United States, with about 12% of people 12 years of age or older reporting use in the past year and particularly high rates of use among young people.1 The most common route of administration is inhalation. The greenish-gray shredded leaves and flowers of the Cannabis sativa plant are smoked (along with stems and seeds) in cigarettes, cigars, pipes, water pipes, or “blunts” (marijuana rolled in the tobacco-leaf wrapper from a cigar). Hashish is a related product created from the resin of marijuana flowers and is usually smoked (by itself or in a mixture with tobacco) but can be ingested orally. Marijuana can also be used to brew tea, and its oil-based extract can be mixed into food products. The regular use of marijuana during adolescence is of particular concern, since use by this age group is associated with an increased likelihood of deleterious consequences2 (Table 1). Although multiple studies have reported detrimental effects, others have not, and the question of whether marijuana is harmful remains the subject of heated debate. Here we review the current state of the science related to the adverse health effects of the recreational use of marijuana, focusing on those areas for which the evidence is strongest.
Randomised controlled trial of high concentration versus titrated oxygen therapy in severe exacerbations of asthma.

BACKGROUND
The effect on Paco2 of high concentration oxygen therapy when administered to patients with severe exacerbations of asthma is uncertain.


METHODS
106 patients with severe exacerbations of asthma presenting to the Emergency Department were randomised to high concentration oxygen (8 l/min via medium concentration mask) or titrated oxygen (to achieve oxygen saturations between 93% and 95%) for 60 min. Patients with chronic obstructive pulmonary disease or disorders associated with hypercapnic respiratory failure were excluded. The transcutaneous partial pressure of carbon dioxide (Ptco2) was measured at 0, 20, 40 and 60 min. The primary outcome variable was the proportion of patients with a rise in Ptco2 ≥4 mm Hg at 60 min.


RESULTS
The proportion of patients with a rise in Ptco2 ≥4 mm Hg at 60 min was significantly higher in the high concentration oxygen group, 22/50 (44%) vs. 10/53 (19%), RR 2.3 (95% CI 1.2 to 4.4, p<0.006). The high concentration group had a higher proportion of patients with a rise in Ptco2 ≥8 mm Hg, 11/50 (22%) vs. 3/53 (6%), RR 3.9 (95% CI 1.2 to 13.1, p=0.016). All 10 patients with a final Ptco2 ≥45 mm Hg received high concentration oxygen therapy, and in five there was an increase in Ptco2 ≥10 mm Hg.


CONCLUSION
High concentration oxygen therapy causes a clinically significant increase in Ptco2 in patients presenting with severe exacerbations of asthma. A titrated oxygen regime is recommended in the treatment of severe asthma, in which oxygen is administered only to patients with hypoxaemia, in a dose that relieves hypoxaemia without causing hyperoxaemia.

Syzygium cumini and the regeneration of insulin positive cells from the pancreatic duct Syzygium cumini e a regeneração de células insulino- positivas a partir do ducto pancreático

Syzygium cumini is a plant that has been used in popular medicine for the treatment of insulin dependent diabetes mellitus (DMID). This study verified the effect of Syzygium cumini upon the regeneration of insulin producing cells in the pancreatic duct wall. The animals were divided into four groups, control (C), treated control (TC), diabetic control (DC) and treated diabetic (TD). An aqueous extract from Syzygium cumini bark was given by gavage in a daily dose of 1g/kg of body weight. After a thirty day period the animals were euthanized and the pancreas taken to immunohistochemical analysis. In this study, it was observed the positive staining for insulin on cells of the pancreatic duct and connective tissue in the pancreas of TD and TC animals. These results indicate that Syzygium cumini bark extract stimulates development of insulin positive cells from the pancreatic duct epithelial cells. Key-words: Syzygium cumini.
A unified statistical approach for determining significant signals in images of cerebral activation.

We present a unified statistical theory for assessing the significance of apparent signal observed in noisy difference images. The results are usable in a wide range of applications, including fMRI, but are discussed with particular reference to PET images which represent changes in cerebral blood flow elicited by a specific cognitive or sensorimotor task. Our main result is an estimate of the P-value for local maxima of Gaussian, t, chi(2) and F fields over search regions of any shape or size in any number of dimensions. This unifies the P-values for large search areas in 2-D (Friston et al. [1991]: J Cereb Blood Flow Metab 11:690-699) large search regions in 3-D (Worsley et al. [1992]: J Cereb Blood Flow Metab 12:900-918) and the usual uncorrected P-value at a single pixel or voxel.
Effect of Low Perceived Social Support on Health Outcomes in Young Patients With Acute Myocardial Infarction: Results From the VIRGO (Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients) Study

BACKGROUND
Social support is an important predictor of health outcomes after acute myocardial infarction (AMI), but social support varies by sex and age. Differences in social support could account for sex differences in outcomes of young patients with AMI.


METHODS AND RESULTS
Data from the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study, an observational study of AMI patients aged ≤55 years in the United States and Spain, were used for this study. Patients were categorized as having low versus moderate/high perceived social support using the ENRICHD Social Support Inventory. Outcomes included health status (Short Form-12 physical and mental component scores), depressive symptoms (Patient Health Questionnaire), and angina-related quality of life (Seattle Angina Questionnaire) evaluated at baseline and 12 months. Among 3432 patients, 21.2% were classified as having low social support. Men and women had comparable levels of social support at baseline. On average, patients with low social support reported lower functional status and quality of life and more depressive symptoms at baseline and 12 months post-AMI. After multivariable adjustment, including baseline health status, low social support was associated with lower mental functioning, lower quality of life, and more depressive symptoms at 12 months (all P<0.001). The relationship between low social support and worse physical functioning was nonsignificant after adjustment (P=0.6). No interactions were observed between social support, sex, or country.


CONCLUSION
Lower social support is associated with worse health status and more depressive symptoms 12 months after AMI in both young men and women. Sex did not modify the effect of social support.
The positive outlook study- a randomised controlled trial evaluating the effectiveness of an online self-management program targeting psychosocial issues for men living with HIV: a study protocol

BACKGROUND
The emergence of HIV as a chronic condition means that people living with HIV are required to take more responsibility for the self-management of their condition, including making physical, emotional and social adjustments. This paper describes the design and evaluation of Positive Outlook, an online program aiming to enhance the self-management skills of gay men living with HIV.


METHODS/DESIGN
This study is designed as a randomised controlled trial in which men living with HIV in Australia will be assigned to either an intervention group or usual care control group. The intervention group will participate in the online group program 'Positive Outlook'. The program is based on self-efficacy theory and uses a self-management approach to enhance skills, confidence and abilities to manage the psychosocial issues associated with HIV in daily life. Participants will access the program for a minimum of 90 minutes per week over seven weeks. Primary outcomes are domain specific self-efficacy, HIV related quality of life, and outcomes of health education. Secondary outcomes include: depression, anxiety and stress; general health and quality of life; adjustment to HIV; and social support. Data collection will take place at baseline, completion of the intervention (or eight weeks post randomisation) and at 12 week follow-up.


DISCUSSION
Results of the Positive Outlook study will provide information regarding the effectiveness of online group programs improving health related outcomes for men living with HIV.

Perioperative mortality and associated factors in patients undergoing radical nephrectomy.

OBJECTIVE
To determine the incidence and related factors of perioperative mortality associated with radical nephrectomy in patients with renal tumours in a tertiary hospital.


MATERIAL AND METHODS
We conducted a cross-sectional study that reviewed the medical records of patients undergoing radical nephrectomy between January 1, 2007 and December 31, 2011 in a tertiary university hospital (Cali, Colombia). We measured sociodemographic variables and factors that may be associated with perioperative mortality. The statistical analysis was performed using STATA.


RESULTS
We analysed 57 patients who underwent radical nephrectomy, 54.4% of whom were male, whose ages ranged from 14 to 81 years. All tumours had a unilateral presentation; 96.5% of the tumours were solid renal lesions, and 3.5% were cystic lesions. The most frequent histological findings were clear cell (63.2%), papillary (8.7%) and chromophobe cell (5.2%) renal carcinoma. There were no complications in 27 (47.3%) of the patients. According to the Clavien-Dindo classification of surgical complications, 16 (28%) patients had minor (grades i and ii) complications and 9 (15.6%) had major (grades iii and iv) complications, with an overall perioperative mortality (grade v) of 8.7% (5 patients).


CONCLUSIONS
The perioperative mortality at 30 days for patients with nonmetastatic renal carcinoma who underwent radical nephrectomy at a tertiary university hospital in Cali, Colombia, was 4.1% (2 patients).
ATR-FTIR spectroscopic analysis of sorption of aqueous analytes into polymer coatings used with guided SH-SAW sensors

Attenuated total internal reflectance Fourier transform infrared (ATR-FTIR) spectroscopy was used for the investigation of sorption of aqueous solutions of analytes into polymer coatings. A series of simple model polymers, such as poly(dimethylsiloxane), poly(epichlorhydrin), and poly(isobutylene), and films and analytes, such as aqueous solutions of ethylbenzene, xylenes, toluene, and nitrobenzene, were used to evaluate the use of ATR-FTIR spectroscopy as a screening tool for sensor development. The ratios of integrated infrared absorption bands provided a simple and efficient method for predicting trends in partition coefficients. Responses of polymer-coated guided shear horizontal surface acoustic wave (SH-SAW) sensor platforms to the series of analytes, using polymer coatings with similar viscoelastic properties, were consistent with ATR-FTIR predictions. Guided SH-SAW sensor responses were linear in all cases with respect to analyte concentration in the tested range. Comparison of ATR-FTIR data with guided SH-SAW sensor data identifies cases where mass loading is not the dominant contribution to the response of the acoustic wave sensor. ATR-FTIR spectra of nitrobenzene, coupled with computational chemistry, provided additional insight into analyte/polymer interactions.
