A systematic search for articles was performed of four different databases, using the descriptor "cannabinoids and oral fluid". Forty-seven studies that examined quantitative methods were identified. The analytical data described in these articles, including oral fluid collection, sample preparation, cannabinoids recovery and extraction efficiency, detection instruments, and quantification limits, were analyzed. The discussion of these particular features of cannabinoid analysis in oral fluid could help to improve or to develop methods for use in Forensic Toxicology.
Socio-economic-status (SES) has rarely been reported or investigated in eating disorders (EDs) research. This Research Forum considers, from various perspectives, how SES may impact on evaluating evidence-based treatments for EDs.
We first reviewed previous literature that informs how SES impacts prevalence of EDs, help-seeking, and treatment outcome. We then present findings from a case series effectiveness study of an early intervention program in low SES areas for EDs and discuss implications about the impact of SES on the effectiveness of evidence-based interventions. Finally, we examine barriers to conducting rigorous evaluations in this population and discuss directions for future treatment outcome research.
Evidence suggests a higher level of disordered eating but less help seeking in lower SES groups. In our case series, 96 participants started treatment and completed a mean of 13.85 sessions, 84 (87.5%) completed a mean of 6.40 sessional measures on ED cognitions and behaviors, but only 31% completed more extensive pre-treatment and post-treatment measures. The completer effect size decrease for the global Eating Disorder Examination-Questionnaire score was 2.05 (95% CI 1.43, 2.68) commensurate with other effectiveness studies in mixed SES groups. The high rates of missing data related to more extensive assessment present a barrier to evaluating evidence-based treatments in this population.
Evidence from the present study revealed individuals from low SES can achieve similar treatment outcomes to other populations when receiving evidence-based ED treatment. Future studies should investigate a range of approaches to maximizing data collection, including use of shorter sessional measures.

Magnetic resonance (MR) imaging is an essential diagnostic tool in clinical medicine. Recently, a variety of deep-learning methods have been applied to segmentation tasks in medical images, with promising results for computer-aided diagnosis. For MR images, effectively integrating different pulse sequences is important to optimize performance. However, the best way to integrate different pulse sequences remains unclear. In addition, networks trained with a certain subset of pulse sequences as input are unable to perform when given a subset of those pulse sequences. In this study, we evaluate multiple architectural features and characterize their effects in the task of metastasis segmentation while creating a method to robustly train a network to be able to work given any strict subset of the pulse sequences available during training.
We use a 2.5D DeepLabv3 segmentation network to segment metastases lesions on brain MR's with four pulse sequence inputs. To study how we can best integrate MR pulse sequencech input features are most important for network performance.
Together, these results provide a framework for building networks with enhanced robustness to missing data while maintaining comparable performance in medical imaging applications.

To examine racial/ethnic differences in use of high-quality hospitals in patients treated for oral cancer in California.
Retrospective cancer database cohort study.
Data were extracted from the California Cancer Registry data set linked with discharge records and hospital characteristics from the California Office of Statewide Health Planning and Development, and with neighborhood characteristics from the California Neighborhoods Data System. The study cohort comprised adult patients with oral cavity malignancy diagnosed between 2004 and 2015. Principal component analysis was used to generate the composite oral cancer-specific hospital quality score. The impact of hospital quality on survival was assessed using Cox regression models with robust standard error using sandwich variance estimators. Poisson regression models with robust error variance were used to assess the association between race/ethnicity and use of high-quality hospitals.
Patients treated in hospitals ranked in the top quartile for quality had improved overall survival (hazard ratio 0.86, 95% confidence intervals [CI] 0.76-0.98), after adjusting for tumor stage, Charlson comorbidity score, neck dissection, radiotherapy, age, sex, race, and insurance status. Black patients (risk ratio 0.87, 95% CI 0.77-0.98) were less likely to be treated in high-quality hospitals compared with non-Hispanic White patients.
Treatment in high-quality hospitals is associated with improved survival for patients with oral cancer. However, black patients are less likely to be treated in high-quality hospitals compared with non-Hispanic white patients.

Since the 1990s, increasing research has been devoted to the identification of biomarkers for autism to help attain more objective diagnosis; enable early prediction of prognosis; and guide individualized intervention options. Early studies focused on the identification of genetic variants associated with autism, but more recently, research has expanded to investigate neurodevelopmental markers. While ethicists have extensively discussed issues around advances in autism genomics, much less ethical scrutiny has focused on research on early neurodevelopment and on the interventions being developed as a result.
We summarize the current state of the science on the identification of early markers for autism and its potential clinical applications, before providing an overview of the ethical issues arising from increasing understanding of children's neurodevelopment in very early life.
Advances in the understanding of brain and behavioral trajectories preceding later autism diagnosis raise ethical concerns arsm researchers to anticipate early interventions that serve the community's interests and accommodate the varied experiences and preferences of people on the spectrum and their families.
The intralaminar thalamus is well implicated in the processes of arousal and attention. Stimulation of the intralaminar thalamus has been used therapeutically to improve level of alertness in minimally conscious individuals and to reduce seizures in refractory epilepsy, both presumably through modulation of thalamocortical function. JAK inhibitor Little work exists that directly measures the effects of intralaminar thalamic stimulation on cortical physiological arousal in humans. Therefore, our goal was to quantify cortical physiological arousal in individuals with epilepsy receiving thalamic intralaminar deep brain stimulation.
We recorded scalp electroencephalogram (EEG) during thalamic intralaminar centromedian (CM) nucleus stimulation in 11 patients with medically refractory epilepsy. Participants underwent stimulation at 130Hz and 300µs for periods of 5 min alternating with 5 min of rest while stimulus voltage was titrated upward from 1 to 5V. EEG signal power was analyzed in different frequency ranges in relationreases in alpha frequency power are generally associated with states of cortical activation and increased arousal/attention. Our observed changes therefore support the possible role of cortical activation and increased physiological arousal in therapeutic effects of intralaminar thalamic stimulation for improving both epilepsy and attention. Further investigations with this approach may lead to methods for determining optimal deep brain stimulation parameters to improve clinical outcome in these disorders.Apatinib has experienced a long-term study in enhancing the sensitivity of various cancer cells to chemotherapy drugs. Currently, researches show that apatinib could attenuate the resistance of gastric cancer (GC) cells to paclitaxel (PTX), but the mechanism has not been fully elucidated, which therefore was explored in this study. PTX-resistant GC cell, namely HGC-27R, was established by exposure to stepwise-increasing PTX. The cell viability of HGC-27 and HGC-27R under PTX or apatinib at different concentrations was assessed by CCK-8 assay, while scratching test and invasion assay were used for investigating the harmful influence of GC cells resistance to PTX. The function of apatinib in HGC-27R was studied by performing functional experiments (flow cytometry, scratching test, and invasion assay). Western blot was performed to measure the expressions of proteins concerning apoptosis, epithelial-mesenchymal transition and janus-activated kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. PTX-resistant GC cell, namely HGC-27R, was successively constructed. HGC-27R cells showed resistance to PTX by promoting migratory and invasive capabilities. Apatinib not only inhibited cell viability of HGC-27 and HGC-27R, but also combined with PTX to suppress that of HGC-27R. Apatinib enhanced apoptosis, diminished migration and invasion of HGC-27R cells, elevated proapoptotic protein expression, and reduced Bcl-2, vimentin, snail, MMP-3, MMP-2, and MMP-9 expressions. The phosphorylation of JAK2 and STAT3 was repressed by apatinib. JAK2 partially reversed the effect of apatinib on enhancing sensitivity of GC cells to PTX. Apatinib strengthened sensitivity of GC cells to PTX by inhibiting JAK/STAT3 signaling pathway.
In epilepsy surgery, which aims to treat seizures and thereby to improve the lives of persons with drug-resistant epilepsy, the chances of attaining seizure relief must be carefully weighed against the risks of complications and expected adverse events. The interpretation of data regarding complications of epilepsy surgery and invasive diagnostic procedures is hampered by a lack of uniform definitions and method of data collection.
Based on a review of previous definitions and classifications of complications, we developed a proposal for a new classification. This proposal was then subject to revisions after expert opinion within E-pilepsy, an EU-funded European pilot network of reference centers in refractory epilepsy and epilepsy surgery, later incorporated into the ERN (European Reference Network) EpiCARE. This version was discussed with recognized experts, and a final protocol was agreed to after further revision. The final protocol was evaluated in practical use over 1year in three of the participati life.
