Thus, these results contribute to investigating the regional change of mechanical properties of skeletal muscle, particularly those of ECM that play a major role in stiffness tissue, which is essential for the development of accurate computational models.Mechanical properties are among the key considerations for the design and fabrication of complex tissue models and implants. In addition to the choice of material and the processing technique, the solvent system can significantly influence the mechanical properties of scaffolds. Poly(ε-caprolactone) (PCL) has been abundantly used to develop constructs, fibrous in particular, for pharmaceutical and biomedical research due to the flexibility offered by PCL-based fibrous matrices. The effect of solvent type on the morphological features of electrospun fibres has been extensively studied. Nevertheless, comprehensive studies on the impact of the solvent system on the mechanical properties of electrospun PCL fibres are lacking. This study elucidates the relationship between topographical, physical and mechanical properties of electrospun PCL fibrous meshes upon using various solvent systems. The results of the mechanical investigation highlight the significance of inter-fibre bonds on the mechanical properties of the bulk membranes and that the option of altering the solvent system composition could be considered for tuning the mechanical properties of the PCL scaffolds to serve specific biomedical application requirements. The applicability of the developed membranes as artificial ECM (Extracellular matrix) in the lung will then be investigated and compared to the commercial Polycarbonate (PC) membranes that are often used for in vitro lung models.

To investigate the opinions of physicians about brain surgery for drug-resistant epilepsy worldwide.

Practicing neurologists, psychiatrists, and neurosurgeons from around the world were invited to participate in an online survey. The survey anonymously collected data about demographics, years in clinical practice, discipline, nation, work setting, and answers to the questions about beliefs and attitudes about brain surgery for drug-resistant epilepsy.

In total, 1410 physicians from 20 countries and different world regions participated. The propensity to discuss brain surgery with patients, who have drug-resistant seizures, was higher among men (versus women) [Odds Ratio (OR) 1.67, 95% CI 1.20-2.31; p=0.002]. In comparison to neurologists, psychiatrists were less likely (OR 0.28, 95% CI 0.17-0.47; p<0.001) and neurosurgeons were more likely (OR 2.00, 95% CI 1.08-3.72; p=0.028) to discuss about it. Survey participants working in Africa, Asia, the Middle East, and the Former Union of Soviet Socialist Republics showed a lower propensity to discuss epilepsy surgery with patients.

This study showed that on an international level, there is still a knowledge gap concerning epilepsy surgery and much needs to be done to identify and overcome barriers to epilepsy surgery for patients with drug-resistant seizures worldwide.

There is growing evidence in the literature that COVID-19 may have negative effects on mental illness in patients and in healthy populations. The unprecedented changes brought about by COVID-19, such as social isolation, school closures, and family stress, negatively affect people's mental health, especially that of children and adolescents. The purpose of this paper is to review the literature and summarize the impact of COVID-19 disorders on children's and adolescents' mental health, the mechanisms and risk factors, screening tools, and intervention and prevention. We hope that the mental dysfunction caused by the pandemic will be mitigated through appropriate and timely prevention and intervention.Psychotic-like experiences (PLEs) are subclinical psychotic symptoms in the general population which are linked to increased risks for later psychiatric disorders. Male and female adolescents were reported to experience PLEs differently, but the results were mixed in previous studies. This study aimed to investigate possible sex differences in the prevalence of adolescent PLEs using a large pooled sample. A total of 21,248 Chinese adolescents aged 11 to 19 years were included, which were drawn from five separate cross-sectional surveys undertaken between 2015 to 2021 in China. PLEs were measured by the 8-item Community Assessment of Psychic Experiences. Using binary logistic regression analyses, no significant sex differences were found in the overall prevalence of PLEs after controlling for age and dataset effects. As for specific PLE subtypes, however, being female was associated with a higher prevalence of delusion of reference and a lower prevalence of visual hallucinations. Furthermore, post-hoc subgroup analyses showed that the sex differences in visual hallucinations persist across both early ( 14 years old) adolescence, while differences in the delusion of reference were significant in only early adolescence. These findings may help us to further understand the biological basis of PLEs.This non-concurrent controlled intervention study aimed to examine the effectiveness of the Mindfulness - Based Therapy and Counseling programs (MBTC) on the treatment of methamphetamine use disorder among 70 individuals (37 females) receiving methamphetamine dependency treatment. Participants were divided into a control group undergoing the usual program and an experimental group using MBTC plus the usual program at a treatment center in Thailand. The study was conducted using the Methamphetamine Craving Questionnaire, urine Color Immunochromatographic Assay and the Mini-International Neuropsychiatric Interview. Stress, depression, and mindfulness were also assessed. MBTC comprised of practicing mindfulness for 90-120 min weekly for eight weeks. Participants were assessed before and after the treatment(s) and at follow-ups visits at 2, 4, 8, 12, and 24 weeks. Mean age (30.3 ± 5.8 years), age of first methamphetamine use (18.2 ± 4.5 years) and other demographics did not differ between groups. At six-month follow-up, the experimental group had significantly lower craving (-7.89, 95%CI = -15.47, -0.32), stress (-7.44, 95%CI = -12.21, -2.67), and depression (-2.95, 95%CI = -5.31, -0.6) and statistically significant higher mindfulness scores (12.86, 95%CI = 9.37, 16.35) than the control group. In addition, methamphetamine relapse in the MBTC group (5/35, 14.3%) was significantly lower than the control group (16/35, 45.7%).It is suggested studying phenotypes within the syndrome of schizophrenia will accelerate understanding the complex molecular pathology of the disorder. Supporting this hypothesis, we have identified a sub-group within schizophrenia with impaired working memory (WM) and have used Affymetrix™ Human Exon 1.0 ST Arrays to compare their blood RNA levels (n=16) to a group of with intact WM (n=18). Levels of 72 RNAs were higher in blood from patients with impaired WM, 11 of which have proven links to the maintenance of different aspects of working memory (cognition). Overall, changed gene expression in those with impaired WM could be linked to cognition through glutamatergic activity, olfaction, immunity, inflammation as well as energy and metabolism. SAdenosylLhomocysteine Our data gives preliminary support to the hypotheses that there is a working memory deficit phenotype within the syndrome of schizophrenia with has a biological underpinning. In addition, our data raises the possibility that a larger study could show that the specific changes in gene expression we have identified could prove to be the biomarkers needed to develop a blood test to identify those with impaired WM; a significant step toward allowing the use of personalised medicine directed toward improving their impaired working memory.

Evidence exists reporting a high mental health burden among migrants globally. However, there is no global estimate of mental ill-health among African migrants despite their adverse pre-migration environments. This systematic review and meta-analysis summarise the current scholarship regarding the prevalence of anxiety, depression and Post-traumatic Stress Disorder (PTSD) in the global African migrant population.

We searched six databases (Medline (EBSCOHost), PsycINFO (EBSCOHost), Web of Science, PubMed, Scopus and Cumulative Index to Nursing and Allied Health (CINAHL) from 1st January 2000 to 31st August 2021. We screened retrieved articles using strict inclusion and exclusion criteria. Study quality was assessed using the Joanna Briggs Institute Critical Appraisal tools. Random-effects meta-analyses were employed using DerSimonian and Laird estimator based on inverse variance weights. The I

statistic was used to measure heterogeneity.

Our search retrieved 1091 articles, of which 46 were included rey, depression, and PTSD among African migrants. Our findings underscore the need to develop and implement serious, culturally appropriate mental health interventions that address post-migration stressors that increase their risk of mental ill-health and successful integration into host communities.

Despite significant heterogeneity among included studies, our systematic review and meta-analysis show a high prevalence of anxiety, depression, and PTSD among African migrants. Our findings underscore the need to develop and implement serious, culturally appropriate mental health interventions that address post-migration stressors that increase their risk of mental ill-health and successful integration into host communities.

Children with late-onset (2-5 years) or persistent (3 months-5 years) sleep-related breathing disorder (SRBD) have an increased risk of behavior problems compared to children with no or early-onset SRBD. We sought to determine whether a combination of urine metabolites and sleep questionnaires could identify children at risk for SRBD-associated behavior problems.

Urine and data were analyzed from the Edmonton site of the CHILD birth cohort study. We measured urine metabolites (random, mid-stream) at age three-years among a sub-cohort of participants (n=165). Random Forest with a Boruta wrapper was used to identify important metabolites (creatinine-corrected, z-scores) for late/persistent SRBD versus no/early SRBD (reference). An algorithm was subsequently generated to predict late/persistent SRBD in children with a history of snoring using a metabolite composite score (z-scores<or≥0) plus the SDBeasy score defined as [age (yrs.) of most recent positive SRBD]

- [age (yrs.) first reported ever snoring]

.

Of the 165 children with SRBD data, 40 participants had late/persistent SRBD. Seven urinary metabolites in addition to the SDBeasy score were confirmed as important for late/persistent SRBD (AUC=0.87). Among children with an ever-snoring history and a metabolite composite score ≥0, those with SDBeasy score ≥3 were over 13-fold more likely to have late/persistent SRBD (OR 13.7; 95%CI 3.0, 62.1; p=0.001). This algorithm has a Sensitivity of 69.6%, Specificity of 85.7% and a positive likelihood ratio (+LR) of 4.9.

We developed a predictive algorithm using a combination of questionnaires and urine metabolites at age three-years to identify children with late/persistent SRBD by five-years of age.
