The aim of this research is the study of metabolic pathways related to oral cancer and periodontitis along with development of machine-learning model for elucidation of these diseases based on saliva metabolites of patients.

Data mining, metabolomic pathways analysis, study of metabolite-gene networks related to these diseases. Machine-learning and deep-learning methods for development of the model for recognition of oral cancer versus periodontitis, using patients' saliva.

The most accurate classifications between oral cancer and periodontitis were performed using neural networks, logistic regression and stochastic gradient descent confirmed by the separate 10-fold cross-validations. The best results were achieved by the deep-learning neural network with the TensorFlow program. Accuracy of the resulting model was 79.54%. The other methods, which did not rely on deep learning, were able to achieve comparable, although slightly worse results with respect to accuracy.

Our results demonstrate a possibility to distinguish oral cancer from periodontal disease by analysis the saliva metabolites of a patient, using machine-learning methods. These findings may be useful in the development of a non-invasive method to aid care providers in determining between oral cancer and periodontitis quickly and effectively.

Refugee children have been shown to underutilise psychiatric services in Scandinavia. The aim of this study was to investigate determinants of psychiatric care utilisation in adolescents in refugee families.

The study used regional data on healthcare use linked to sociodemographic data from national registers in a total population of 93537 adolescents in the Stockholm County born in 1995-2000, including 18831 with a refugee background. Cox regression analyses were fitted to estimate Hazard ratios (HRs) of psychiatric care utilisation in the age-span 11-18years.

Psychiatric care use was lower in the large majority of adolescents in refugee families that originated in low- and middle-income countries, with adjusted HRs 0.34 (95% CI 0.28-0.42) and 0.51 (95% CI 0.46-0.56), respectively, compared with the Swedish majority population. Among the foreign-born refugee adolescents, psychiatric care use increased with duration of residence in Sweden and was higher in children who obtained residency as asylum seekers compared with those who settled in family reunification.

Adolescents in newly settled refugee families with a background in low- and middle-income countries should be a priority in mental health assessment of refugee children and referral to psychiatric care facilitated for children in need.

Concurrently, scholarly research has given rise to a number of articles, white papers, and books on humanitarian insecurity. Most of this research centers on external threats while neglecting the internal mechanisms that humanitarian organizations employ to mitigate security incidents. This article builds on existing literature by focusing on humanitarian organizations' decision-making processes. The article uses data collected from 16 Security Managers/Advisors. The results reveal several factors contribute to contextual uncertainty and complexity, including recipient perceptions, local governments, the behavior of other NGOs in the area, logistical issues, variances in risk within a single location, and organizational mandate. Results further indicate that NGOs use a combination of decision processes to determine how to manage security in high risk situations. This article is protected by copyright.

Macrophages are the predominant cell type in acute inflammatory brain lesions in MS. Macrophages produce proinflammatory and toxic molecules that promote demyelination and are key players in phagocytosis/degradation of myelin sheathes. Lipoic acid (LA) is an inexpensive, endogenously produced small molecule that exhibits antioxidant and anti-inflammatory effects. Treatment with LA is protective in MS and other inflammatory diseases. To examine the mechanism(s) by which LA may attenuate inflammatory lesion activity in MS, we used healthy control and MS cells to evaluate the effects of LA on levels of inflammatory cytokines, phagocytosis and the immunomodulator cyclic adenosine monophosphate (cAMP) in monocytes and monocyte-derived macrophages (MDMs). LA treatment resulted in a generally less inflammatory phenotype of monocytes and MDMs from healthy controls, and (to a lesser degree) MS donors. LA inhibited monocyte secretion of cytokines relevant to MS in monocytes, including tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1β; LA effects on secretion of these cytokines in MDMs were mixed with inhibition of TNF-α and IL-6, but stimulation of IL-1β, the latter perhaps as a result of altered macrophage polarization. LA inhibited phagocytosis in both monocytes and MDMs, and increased cAMP levels in monocytes. LA may modulate inflammatory cytokine secretion and phagocytosis via a cAMP-mediated mechanism.Loss of function mutations within the vesicular trafficking protein Ras analogy in brain 39B (RAB39B) are associated with rare X-linked Parkinson's disease (PD). Physiologically, RAB39B is localized to Golgi vesicles and recycling endosomes and is required for glutamatergic receptor maturation but also for alpha-Synuclein (aSyn) homeostasis and the inhibition of its aggregation. Despite evidence linking RAB39B to neurodegeneration, the involvement of the protein in idiopathic neurodegenerative diseases remains undetermined. Here, analysis of the spatial distribution and expression of RAB39B was conducted in post-mortem human brain tissue from cases of dementia with Lewy bodies (DLB, n = 10), Alzheimer's disease (AD, n = 12) and controls (n = 12). Assessment of cortical RAB39B immunoreactivity using tissue microarrays revealed an overall reduction in the area of RAB39B positive gray matter in DLB cases when compared to controls and AD cases. Strikingly, RAB39B co-localized with beta-amyloid (Aβ) plaques in all cases examined and was additionally present in a subpopulation of Lewy bodies (LBs) in DLB.
