Purpose Olanzapine (OLZ) is an atypical antipsychotic agent that is characterized by low brain porousness due to hepatic first-pass metabolism. The present work aimed to develop radiolabeled OLZ and evaluate its biodistribution following intravenous (I.V.) and intranasal (I.N.) administration as a potential agent for brain diagnosis. The effect of colloidal tin oxides on the biodistribution of technetium-99m radiolabeled OLZ has been overcome by using sodium dithionite as a reducing agent instead of the commonly used stannous salts for the reduction of 99mTc (VII) to the lower valence state.Materials and methods OLZ was radiolabeled with technetium-99m (99mTc) by direct technique using sodium dithionite as the reducing agent. This approach illustrated appropriate labeling efficacy, stability, and potential for further use in biodistribution studies. Therefore, it provides an alternative for the labeling procedure, which utilizes stannous chloride and leads to the formation of colloidal stannic oxides that aff exposure than free OLZ.Conclusion These chemical and preliminary biological merits strongly suggest that the 99mTc-OLZ complex with new reducing agent could be used as a potential diagnostic agent for brain.Introduction In this study we estimated the rate and the trajectory of cognitive impairment in a naturalistic sample of outpatients with major depressive disorder (MDD) and bipolar disorder (BD) and its correlation with different variables.Materials and methods An overall sample of 109 outpatients with MDD or BD was assessed for multiple clinical variables, including duration of untreated illness (DUI), and tested using the Montreal Cognitive Assessment (MoCA) during Major Depressive Episodes (MDE) and after remission. Correlations between MoCA scores and the clinical variables were then computed.Results About 50% of patients with MDD and BD showed mild cognitive impairment during MDE. Improvement of cognitive function between depression and remission was significant, even though residual symptoms were observed especially in the most impaired patients. Of note, cognitive performance during depression was negatively associated with depression severity and DUI.Discussion Present findings confirm available evidence about patterns of cognitive impairment in mood disorders, in terms of prevalence and persistence beyond remission in most severe cases. Moreover, a longer DUI was associated with worse cognitive performance during depression, and consequently with poorer outcome, underlining the importance of prompt treatment of these disorders also in light of a cognitive perspective.KeypointsAlthough distinct entities, unipolar and bipolar depression determine similar patterns of cognitive impairment in terms of severity and types of altered domains.Depression (but not anxiety) severity is associated with cognitive performance in depression.Prolonged duration of untreated illness is associated with more severe cognitive impairment during depression, particularly but not specifically in bipolar disorder.Background In divorce research, studies using large samples, very recently divorced individuals and validated measures of depression and anxiety with available background populations for comparison are missing.Aims This study aimed to investigate symptoms of depression and anxiety among recently divorced Danes and assess the explanatory power of relevant sociodemographic- and divorce-related variables on these symptoms.Methods The study utilized an online cross-sectional design and a total of 1856 Danish citizens recruited through the Danish State Administration. Average scores for depression and anxiety were compared to the Danish background population and regression analyses were conducted to assess the explanatory power of sociodemographic- and divorce characteristics on symptoms of depression and anxiety.Results Divorcees reported significantly higher levels of both depressive and anxiety symptoms than the background population with a large proportion of the sample scoring equal to or higher than generally recommended cut-off values for risk of suffering from a psychiatric diagnosable case of depression or anxiety. Both sociodemographic- and divorce characteristics were predictive of symptoms of depression and anxiety.Conclusion The findings underline the relevance of public health intervention targeting symptoms of depression and anxiety among recently divorced individuals.Metformin hydrochloride (MFM) is often used as a controlled-release (CR) tablet to reduce dosing frequency. However, the MFM CR tablet contains significant amounts of excipients and the tablet size is also large. Dosing convenience and patient compliance can be increased by reducing the size of the CR tablets. The aim of this study was to prepare and evaluate the MFM controlled-release tablet (MFM-CRT) using two types of release modulators, inner and outer. The MFM-CRT was prepared by coating the MFM granules using a binder solution containing aluminum stearate (ALS) as the inner release-modulator, and polyethylene oxide (PEO) as the outer release-modulator. The dispersion stability of the binder solution was optimized by the dispersion analyzer. The MFM-CRT was evaluated for dissolution rate and tablet volume. Additionally, dissolution behavior and dissolution kinetics of the MFM-CRT were analyzed using micro-computed tomography (micro-CT). Although the optimal MFM-CRT showed no difference in the release rate as compared to the commercially available product of Glucophage® XR 500 mg (f2 value 72), the length of the long axis was reduced by 6 mm and the weight was reduced by about 27%. We expect patient compliance to improve because of effective sustained release and volume reduction of MFM-CRT.Objective To evaluate ultralight folding manual wheelchairs (UFMWs) in order to produce comparative data on their strength, durability, stability and cost-benefit, and to determine progress of wheelchairs by comparing these results to results of past studies.Design Engineering testing using American National Standards Institute (ANSI) and Rehabilitation Engineering and Assistive Technology Society of North America (RESNA) standards.Setting Laboratory testing of UFMW stability, and static, impact and fatigue strength performance with three devices using ANSI/RESNA standardized tests.Participants The three wheelchair models were the TiLite Aero X (Permobil, Lebanon, TN), Sunrise Medical Quickie 2 (Fresno, CA) and Ki Mobility Catalyst 5 (Stevens Point, WI).Interventions ANSI/RESNA standardized tests.Main outcome measures Mass and critical measurements, static stability, static strength, impact strength, fatigue strength and cost analysis.Results The ultralight folding wheelchairs continued to outperform their lied, decreased or remained the same over the years. Other wheelchair types have remained stagnant with respect to durability and are less likely to meet the minimum durability requirements.Durable devices will improve a wheelchair user's quality of life by reducing downtime while waiting for repairs, and also reduce the likelihood of injury due to component failure.Introduction Subependymal ependymal giant cell astrocytomas (SEGAs) occur almost exclusively in the setting of tuberous sclerosis (TSC). They are low-grade gliomas which typically produce clinical symptoms through either mass effect or hydrocephalus. As do other manifestations of tuberous sclerosis, these lesions result from mutations in either the TSC1 or the TSC2 gene. These mutations cause hyperactivation of the mechanistic target of rapamycin (mTOR). In view of their tendency to grow slowly, clinical symptoms usually only occur when the tumors reach a considerable size. Therapy can involve surgical resection, cerebrospinal fluid diversion, or medical therapy with an mTOR inhibitor.Areas covered Herein, the authors discuss the diagnosis, symptoms, and practical management of SEGAs as well as providing their expert opinion.Expert opinion mTOR inhibitors have largely replaced surgery as the primary modality for the management of SEGAs. Surgical treatment is largely limited to tumors that present with acute hydrocephalus and increased intracranial pressure. Patients with TSC should undergo periodic screening with CT or preferably MRI scans of the brain from childhood to approximately age 25 to identify SEGAs which require treatment. In addition to avoiding potential morbidity associated with surgical resection, mTOR inhibitors have the potential to improve the clinical status of tuberous sclerosis patients generally.Aim To assess time-to-treatment discontinuation (TTD) of brigatinib following treatment with ALK tyrosine kinase inhibitor(s) (TKIs) in patients with ALK-positive (ALK+) non-small-cell lung cancer (NSCLC) receiving brigatinib through the international early access program. Patients & analysis Analysis was performed for patients with ALK+ NSCLC treated with prior ALK TKIs, including next-generation ALK TKIs. BDA-366 order Results Data for 604 patients (21 countries), including patients with prior next-generation ALK TKIs, were reported. The median TTD of brigatinib in patients with prior crizotinib, alectinib, ceritinib or lorlatinib was 10.0, 8.7, 10.3 and 7.5 months, respectively. Conclusion Brigatinib appears to be effective and tolerable in real-world clinical practice regardless of prior treatment with first or NG ALK TKIs.Objective The objective of this study was to explore the knowledge, attitudes, and practices concerning antibiotic prescriptions to children with URTIs among pediatricians and to identify barriers to appropriate antibiotic prescription among pediatricians.Methods An online-based survey was conducted among pediatricians in Shaanxi province, western China, with a population of 38.35 million and an area of 205,600 square kilometers.Results A total of 472 pediatricians completed this survey, with the response rate of 26.0%. The theoretical knowledge about antibiotics was excellent, with a median score of 8(0-8). However, 30.1% of the respondents still believed that antibiotics are anti-inflammatory drugs. The pediatricians' age, education level, and monthly income and whether had ever received training had significant associations with their knowledge level. The attitude scores were 41.1 ± 3.6, with a ranged of 29-52 points (total score of 55), indicating that most respondents had positive attitudes toward antibiotics. However, 22.7% of the respondents still preferred to use antibiotics for URTIs. It was found that uncertain diagnosis, parent requirements and insufficient time were barriers to appropriate antibiotic prescription. The indiscriminate prescription of antibiotics to children with URTIs was prevalent among pediatricians.Conclusion Effective integrated interventions should be developed to promote the prudent use of antibiotics among pediatricians.Objectives To assess are there learning-related improvements in the speech reception thresholds (SRTs) for the Finnish matrix sentence test (FMST) and the Finnish digit triplet test (FDTT) in repeated use over 12 months.Design Test sessions were scheduled at 0, 1, 3, 6 and 12 months, and each session included five FMST measurements and four FDTT measurements. The within-session and inter-session improvements in SRTs were analysed with a linear mixed model.Study sample Fifteen young normal-hearing participants.Results Statistically significant mean improvements of 2.0 dB SNR and 1.2 dB SNR were detected for the FMST and the FDTT, respectively, over the 12-month follow-up period. For the FMST, majority of the improvement occurred during the first two test sessions. For the FDTT, statistically significant differences were detected only in comparison to the first test session and to the first test measurement of every session over the 12-month follow-up.Conclusions Repeated use of the FMST led to significant learning-related improvements, but the improvements appeared to plateau by the third test session.
