Deep neural networks are increasingly being used in both supervised learning for classification tasks and unsupervised learning to derive complex patterns from the input data. However, the successful implementation of deep neural networks using neuroimaging datasets requires adequate sample size for training and well-defined signal intensity based structural differentiation. There is a lack of effective automated diagnostic tools for the reliable detection of brain dysmaturation in the neonatal period, related to small sample size and complex undifferentiated brain structures, despite both translational research and clinical importance...

The aim of the present study was to develop suitable and reliable method for quantification three of the most worldwide used therapeutic monoclonal antibodies (mAbs) -bevazizumab (BVZ), infliximab (INF) and trastuzumab (TTZ)- to be used in long-term stability studies. Reverse phase (RP) was selected by its greater sensibility and reproducibility comparing with other chromatographic modes. Then a high performance liquid chromatography with diode array detection (RP)HPLC/DAD method was checked. Since the three mAbs represent the active ingredient in the medicines in which they are formulated, the selected method was validated for each one in accordance with the International Conference on Harmonization (ICH) guidelines for pharmaceuticals for human use...

Month ordering tasks have been used in experimental settings to obtain measures of working memory (WM) capacity in older/clinical groups based solely on their face validity. We sought to assess the appropriateness of using a month ordering task in other contexts, including clinical settings, as a psychometrically sound WM assessment. To this end, we constructed a month ordering task (ucMOT), studied its reliability (internal consistency and temporal stability), and gathered construct-related and criterion-related validity evidence for its use as a WM assessment...

This study evaluated whether the Test of Gross Motor Development 3 (TGMD-3) is a reliable tool to compare children with and without mental and behavioral disorders across gross motor skill domains. A total of 1,075 children (aged 3-11 years), 98 with mental and behavioral disorders and 977 without (typically developing), were included in the analyses. The TGMD-3 evaluates fundamental gross motor skills of children across two domains: locomotor skills and ball skills. Two independent testers simultaneously observed children's performances (agreement over 95%)...

We examined cultural differences in the item characteristic functions of self-reported of symptoms of depression, anxiety, and mania-hypomania in a Latino population taking Computerized Adaptive Tests for Mental Health (CAT-MH) in Spanish versus a non-Latino sample taking the tests in English. We studied differential item functioning (DIF) of the most common adaptively administered symptom items out of a bank of 1,008 items between Latino (n = 1276) and non-Latino (n = 798) subjects. For depression, we identified 4 items with DIF that were good discriminators for non-Latinos but poor discriminators for Latinos...

Despite a growing body of research documenting the negative impact of racial microaggressions on racial and ethnic minorities' wellbeing, there remains debate in society about whether it is acceptable to say racially microaggressive statements. However, no scale exists to assess attitudes about the acceptability of saying such statements. OBJECTIVES: In this study we present an initial validation of a new scale, the Acceptability of Racial Microaggressions Scale (ARMS), which assesses attitudes about how "okay" it is for White individuals to say different types of racially microaggressive statements to racial and ethnic minorities in an interpersonal interaction...

INTRODUCTION: Formative assessment is a key component in medical education and that it is a helpful process for all involved. Until recently there was no national formative examination for neurosurgical trainees. The Neurosurgery Annual in Training Examination (NAiTE) is an annual online, formative assessment that was introduced in 2014. In this paper, we seek to discuss how well NAiTE relates to established educational practice and principles and its fitness for purpose by discussing its rationale, structure and utility...

Despite the appeal of ultra-short-term heart rate variability (HRV) methods of analysis applied in the clinical and research settings, the number of studies that have investigated HRV by analyzing R-R interval (RRi) recordings shorter than 5 min is still limited. Moreover, ultra-short-term HRV analysis has not been extensively validated during exercise and, currently, no indications exist for its applicability during resistance exercise. The aim of the present study was to compare ultra-short-term HRV analysis with standard short-term HRV analysis during low-intensity, dynamic, lower limb resistance exercise in healthy elderly subjects...

BACKGROUND: empirical evidence suggests that anxiety and depression in cancer patients is underdiagnosed and subsequently this patient population receives little or no support or intervention to address their psychosocial needs. It is often difficult to distinguish between normal emotional distress experienced following a cancer diagnosis and anxiety and depression, which can have a significant impact on coping mechanisms and subsequent outcomes. AIM: a qualitative study using the Hospital Anxiety and Depression Scale (HADS) was undertaken in the National Centre for Cancer Care and Research in Qatar...

OBJECTIVES: Late-onset stress symptomatology (LOSS) is a phenomenon observed in older combat veterans who experience increased combat-related thoughts, feelings, and reminiscences corresponding with the changes and challenges of aging. Previously, we developed the LOSS Scale to assess LOSS. This paper describes the development and validation of a LOSS Scale short form (LOSS-SF) to screen veterans in various settings who may be actively re-examining their past wartime experiences. METHOD: Three studies examined the reliability and validity of the LOSS-SF in separate samples of male combat veterans age 55 and older (total N = 346)...
