Saroush","doi":"10.3371/CSRP.CVKM.081221","DOIUrl":"https://doi.org/10.3371/CSRP.CVKM.081221","url":null,"abstract":"Background: Meningioma's are by far the most frequent primary tumors occurring inside the cranium. Prognostic wise, the problem with grade II and grade III neoplasms is the high recurrence rate following surgical resection. Surgical goal is to offer complete resection of the tumor to avoid future recurrence;however, such complete resection is limited by a number of factors such as the tumor location with the central nervous system, invasion of underlying vital brain tissue, involvement of cranial nerves and invasion of dural sinuses. Therefore, pre-operative imaging assessment of meningioma is necessary and the ability to grade these tumors on sole imaging background is an essential step in order to select the optimum surgical and or radiation based therapy. Aim of the study: In the current systemic review we collected information about radiological features detected by MRI techniques and analyzed these futures statically with respect to accuracy, sensitivity and specificity aiming at providing an MRI criteria predicting atypical grade II and III meningiomas prior to surgical intervention. Materials and methods: The current systematic review was based on the preferred reporting items for systematic reviews and meta-analysis guidelines. The primary objective of the current review was to evaluate the currently published data on the potential role of the technique such as Diffusion Weighted Imaging (DWI), and Apparent Diffusion Coefficient (ADC) for the assessment of meningioma grade. The principal research questions were: 1.What is the sensitivity of magnetic resonance imaging in Grading meningioma for brain?. 2. What is the specificity of magnetic resonance imaging in Grading meningioma for brain?. Results: We found that peritumoral edema, tumor necrosis, apparent diffusion coefficient, diffusion weighted trace, tumor enhancement, dural tail, tumor margin and tumor brain interface are all associated with significant prediction potential with respect to meningioma grade (p<0.05). On the other hand, capsular enhancement, T1-weighted imaging, T2-weighted imaging and tumor location are all insignificant predictors of high grade tumor (p>0.05). Highest sensitivity was seen in association with peritumoral edema (73.0 %). Highest specific level was seen in association with Apparent Diffusion Coefficient (ADC) (90.4 %). Tumor necrosis was associated with highest PPV (61.9 %). Highest negative predictive value was seen in association with shape of tumor margin (85.7 %) and highest level of accuracy was observed in association with tumor brain interface (78.2 %). Conclusion: A number of imaging characteristics in MRI can predict the grade of meningioma prior to surgical intervention including peritumoral edema, tumor necrosis, apparent diffusion coefficient, diffusion weighted trace, tumor enhancement, dural tail, tumor margin and tumor brain interface and the presence of any combination of these characteristics will make the decision even more precise.

Passive sensing technology is a way to collect data on the behaviors and activities of depressed mothers in order to better tailor psychological treatment and improve outcomes for postpartum depression. This study investigated (a) the feasibility and acceptability of wearable digital sensors with adolescent mothers and their families in rural Nepal and (b) the feasibility and utility of implementing this data into a phone based application used by non-specialists to provide personalized psychological treatment. This study used a mobile phone and Bluetooth device to generate passive sensing data on aspects of a mother’s life, such as amount of time spent with and away from the baby, movements and activities both inside and outside of the house, social interactions experienced, and physical activity. We then interviewed both depressed and non-depressed adolescent mothers who used these wearable digital devices and analyzed the ethicality, safety, social acceptability, utility, and feasibility of these technologies. This data was then used to develop Stand Strong, a platform that collects passive sensing data to implement personalized depression treatment. Our results showed that both depressed and non-depressed mothers found it acceptable and feasible to collect passive sensing data. Depressed and non-depressed mothers expressed utility in having knowledge of their own movements and activities, as well as having information about their proximity to and interactions with their child. The non-specialized community counselors expressed utility in using the data collected from the wearable digital sensors to encourage behavioral changes during sessions and also to track the progress of patients between sessions. Barriers to using wearable digital devices included difficulty carrying the phone around throughout the day, privacy concerns, fear of loss or damage to the device, and concern about possible adverse health effects of the device. In summary, it is feasible and acceptable to use passive sensing data to tailor psychological treatment for depressed adolescent mothers in low-resource settings. This research demonstrates the effectiveness of mobile health technology in improving treatment and outcomes for postpartum depression in rural areas.","PeriodicalId":40019,"journal":{"name":"Clinical Schizophrenia and Related Psychoses","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79981219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The course of illness is often exacerbated by relapses which are associated with negative outcomes including rehospitalisation. The most important risk factor associated with relapse is medication nonadherence. Medication nonadherence is not specific to schizophrenia and is an issue across all of medicine. The objective of this paper is to present a narrative review which synthesizes the rates and predictors of medication nonadherence, as well as associated interventions, across schizophrenia, first episode psychosis and general medicine. Given the breadth of these topics, this paper does not aim to present a complete review of the data but rather a concise synthesis of several lines of research in order to provide a general framework for approaching this important topic. Overall, this paper identifies that rates and risk factors of nonadherence in schizophrenia are similar to those reported in general medicine. Rates of adherence are estimated at 50% for both. Predictors of nonadherence were also quite similar between various illnesses, with lack of insight, poor family support and substance abuse often being highlighted. Well studied approaches of improving adherence include simplifying medication regimens, psychoeducation, engaging family support and use of long-acting injectable antipsychotics. Emerging interventions included text-message reminders, financial incentives and MyCite technology. Additionally, several evidence based interventions were identified in general medicine that may have applicability in schizophrenia and first episode psychosis. Lastly, avenues of future research were identified including the need to further characterize the dichotomy between adherence, partial adherence and nonadherence.","PeriodicalId":40019,"journal":{"name":"Clinical Schizophrenia and Related Psychoses","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74669685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
