RESUMEN

Forced migrants suffer from significant psychological distress. However, they often prioritize urgent practical resettlement needs over mental health needs. The present study used a quasi-experimental design to compare pathways of treatment for survivors of torture (N = 369) from 42 different counties receiving care from a refugee health clinic. Random intercept ANOVAs were used to compare combined case management services and psychological treatment (CM-PT) to case management services only (CM) on changes in cultural adaptation and global functioning over time. Results showed that both groups improved on each outcome. Importantly, the CM-PT group endorsed greater improvements in cultural adaptation (b = 0.28, 95% CI 0.14, 0.41, p ≤ 0.001) and global functioning (b = 3.29, 95% CI 1.33, 5.25, p = 0.001) compared to the CM group. These findings suggest that treatment for survivors of torture should be multifaceted and include case management and psychological treatment. Case management services alone may be beneficial when socio-cultural and resource barriers exist for mental health treatment.

RESUMEN

Newcomer Latinx immigrant youths in the United States are currently in a syndemic of increased risk of behavioral health concerns, disparities in access to related services, and are disproportionately impacted by the COVID-19 pandemic. This study used qualitative inquiry to examine the impact that the transition to telehealth had on a school-based group prevention program for immigrant youth, Fuerte, within the context of this syndemic. Data included semi-structured interviews with group leaders, and focus groups with youth program participants. Themes indicated both positive and negative impacts of the transition to telehealth on program component implementation, youth participant engagement, and youth participant social connectedness. Despite the telehealth model, youth participants reported that they felt socially connected to each other through the program. This study's results provide implications for the potential value and drawbacks of a telehealth prevention model for newcomer immigrant youth, as well as deepening understanding of how virtual behavioral health programs may operate in socially isolating contexts around the world.

RESUMEN

Schools play a vital role in the acculturation process of newly migrated youth. Social and academic factors within school settings predict a wide variety of adaptation outcomes. Age and grade also impact the ways that school experiences can shape the post-migration adjustment trajectories of migrant youth. Negative school experiences can exacerbate migration trauma, whereas positive school experiences play an important protective role in overcoming migration-related challenges and adjusting to a new cultural context. Emerging research also suggests that the school environment presents a valuable opportunity for service delivery, as students are readily accessible during the school day which reduces systemic barriers to engagement. Socio-emotional prevention and intervention can address migration trauma, foster resiliency, and help lead the way to acculturative and academic success. Teachers, counselors, coaches and mentors who engage with newcomer immigrant youth in schools can play a pivotal role in easing migration-related challenges by encouraging positive emotional attachments, linking to resources, and helping to navigate new systems. These professionals benefit from specialized training on the unique needs and best practices for supporting the learning, engagement, development, and adaptation of newcomer youth.

RESUMEN

Research suggests that media adherence to suicide reporting recommendations in the aftermath of a highly publicized suicide event can help reduce the risk of imitative behavior, yet there exists no standardized tool for assessing adherence to these standards. The Tool for Evaluating Media Portrayals of Suicide (TEMPOS) allows media professionals, researchers, and suicide prevention experts to assess adherence to the recommendations with a user-friendly, standardized rating scale. An interdisciplinary team of raters constructed operational definitions for three levels of adherence to each of the reporting recommendations and piloted the scale on a sample of articles to assess reliability and clarify scale definitions. TEMPOS was then used to evaluate 220 news articles published during a high-risk period following the suicide deaths of two public figures. Post-hoc analyses of the results demonstrated how data produced by TEMPOS can be used to inform research and public health efforts, and inter-rater reliability analyses revealed substantial agreement across raters and criteria. A novel, wide-reaching, and practical approach to suicide prevention, TEMPOS allows researchers, suicide prevention professionals, and media professionals to study how adherence varies across contexts and can be used to guide future efforts to decrease the risk of media-induced suicide contagion.

RESUMEN

There has been a record surge of unaccompanied immigrant minors (UAMs) entering the United States, with 86% of those apprehended at the US-Mexico border originating from the Central American countries of El Salvador, Guatemala, and Honduras. A majority of immigrant children are separated from either one or both parents at various points during the migration process. Although average separations last 4 or more years, and may be deeply distressing, there is little research on family separations among Central American UAMs. Further, little is known about the developmental impact of separations from extended family networks, or about reunification. To address these empirical gaps, this study used community-participatory qualitative methods to deeply explore the lived experiences and emotional repercussions of family separation and reunification. The sample included 42 adolescents who had all recently migrated to the Western United States from Central America. Thematic analyses revealed that separation experiences are distressing, multifaceted, and have important developmental implications for Central American UAMs. Results illustrate the socioemotional toll that family separation and reunification can have on this vulnerable population, and highlight the need for culturally responsive, developmentally informed, and contextually appropriate care focused on family reunification in order to foster healthy psychosocial adjustment among UAMs.

RESUMEN

Curcumin is a naturally occurring polyphenolic compound present in rhizome of Curcuma longa belonging to the family zingiberaceae. Growing experimental evidence revealed that curcumin exhibit multitarget biological implications signifying its crucial role in health and disease. The current review highlights the recent progress and mechanisms underlying the wide range of pharmacological effects of curcumin against numerous diseases like neuronal, cardiovascular, metabolic, kidney, endocrine, skin, respiratory, infectious, gastrointestinal diseases and cancer. The ability of curcumin to modulate the functions of multiple signal transductions are linked with attenuation of acute and chronic diseases. Numerous preclinical and clinical studies have revealed that curcumin modulates several molecules in cell signal transduction pathway including PI3K, Akt, mTOR, ERK5, AP-1, TGF-ß, Wnt, ß-catenin, Shh, PAK1, Rac1, STAT3, PPARγ, EBPα, NLRP3 inflammasome, p38MAPK, Nrf2, Notch-1, AMPK, TLR-4 and MyD-88. Curcumin has a potential to prevent and/or manage various diseases due to its anti-inflammatory, anti-oxidant and anti-apoptotic properties with an excellent safety profile. In contrast, the anti-cancer effects of curcumin are reflected due to induction of growth arrest and apoptosis in various premalignant and malignant cells. This review also carefully emphasized the pharmacokinetics of curcumin and its interaction with other drugs. Clinical studies have shown that curcumin is safe at the doses of 12 g/day but exhibits poor systemic bioavailability. The use of adjuvant like piperine, liposomal curcumin, curcumin nanoparticles and curcumin phospholipid complex has shown enhanced bioavailability and therapeutic potential. Further studies are warranted to prove the potential of curcumin against various ailments.

RESUMEN

OBJECTIVE: This systematic review aimed to clarify whether there are any significant long-term sequelae to wearing mandibular advancement devices focusing on dental and skeletal effects in adults with OSA. MATERIALS AND METHODS: Databases, including PubMed, Medline, Embase, Web of Science, Cochrane Central Register of Controlled Trials, and SAGE Journals. Hand searches and grey literature were also used. A piloted data collection form was used to extract the appropriate data. RESULTS: Twenty-three reports of 19 studies were included. Five had serious risk of bias while 18 had moderate risk of bias. Meta-analysis revealed a significant change in overbite and overjet. I-squared analysis showed a high level of statistical heterogeneity. A moderate correlation was found between wear time and amount of change. CONCLUSION: Mandibular advancement devices will cause a small but statistically significant change in the dentition of long-term wearers. Skeletal changes are generally secondary to dental changes.

RESUMEN

The present study was aimed to investigate the effect of Urtica dioica Linn. (UD) extract against chronic diabetes mediated anxiogenic and depressive like behavior in mice. Streptozotocin (STZ) (50 mg/kg, i.p.) for 5 consecutive days was used to induce diabetes followed by treatment with UD leaves extract (50 mg/kg, p.o.) and rosiglitazone (ROSI) (5 mg/kg, p.o.) for 8 weeks. STZ induced chronic diabetes significantly induced anxiety and depressive like behavior in mice. Chronic diabetes significantly downregulated BDNF (p < 0.001), TrKB (p < 0.001), Cyclin D1 (p < 0.001), Bcl2 (p < 0.05) and autophagy7 (p < 0.001), while upregulated iNOS (p < 0.05) mRNA expression in the hippocampus as compared to control mice. In addition, chronic diabetes significantly increased the expression of TNF-α in CA1 (p < 0.001), CA2 (p < 0.01), CA3 (p < 0.001) and DG (p < 0.001) regions of hippocampus as compared to control mice. Chronic diabetes mediated neuronal damage in the CA2, CA3 and DG regions of hippocampus. Chronic administration of UD leaves extract significantly reversed diabetes mediated anxiogenic and depressive like behavior in mice. Further, UD treatment significantly upregulated BDNF (p < 0.01), TrKB (p < 0.001), Cyclin D1 (p < 0.001), Bcl2 (p < 0.01), autophagy5 (p < 0.01) and autophagy7 (p < 0.001), while downregulated iNOS (p < 0.05) mRNA expression in the hippocampus of diabetic mice. Concomitantly, UD administration significantly decreased the expression of TNF-α in hippocampal CA1 (p < 0.001), CA2 (p < 0.01), CA3 (p < 0.001) and DG (p < 0.001) regions of diabetic mice. Diabetes mediated neuronal damage and DNA fragmentation in the hippocampus was substantially attenuated following UD treatment. UD leaves extract might prove to be effective for diabetes mediated anxiety and depressive like behavior.

RESUMEN

Alzheimer's disease, a progressive neurodegenerative disease, is characterised by hypofunction of acetylcholine (ACh) neurotransmitter in the distinct region of brain. Acetylcholinesterase (AChE) is an enzyme that metabolises the ACh at synaptic cleft resulting in Alzheimer's disease. Medicinal plants have been used to treat numerous ailments and improve human health from ancient time. A traditional system of medicine is long recognised for its effective management of neurological disorders. The present review confers the scope of some common medicinal plants with a special focus on AChE-mediated central nervous system complications especially Alzheimer's disease. Literature suggests that medicinal plants reduce neuronal dysfunctions by reducing AChE activity in different brain regions. In some instances, activation of AChE activity by medicinal plants also showed therapeutic potential. In conclusion, medicinal plants have a wide scope and possess therapeutic potential to efficiently manage neurological disorders associated with AChE dysregulation.

RESUMEN

This is the first report of a simultaneous ultraviolet/visible/NIR and longwave infrared laser-induced breakdown spectroscopy (UVN + LWIR LIBS) measurement. In our attempt to study the feasibility of combining the newly developed rapid LWIR LIBS linear array detection system to existing rapid analytical techniques for a wide range of chemical analysis applications, two different solid pharmaceutical tablets, Tylenol arthritis pain and Bufferin, were studied using both a recently designed simultaneous UVN + LWIR LIBS detection system and a fast AOTF NIR (1200 to 2200 nm) spectrometer. Every simultaneous UVN + LWIR LIBS emission spectrum in this work was initiated by one single laser pulse-induced micro-plasma in the ambient air atmosphere. Distinct atomic and molecular LIBS emission signatures of the target compounds measured simultaneously in UVN (200 to 1100 nm) and LWIR (5.6 to 10 µm) spectral regions are readily detected and identified without the need to employ complex data processing. In depth profiling studies of these two pharmaceutical tablets without any sample preparation, one can easily monitor the transition of the dominant LWIR emission signatures from coating ingredients gradually to the pharmaceutical ingredients underneath the coating. The observed LWIR LIBS emission signatures provide complementary molecular information to the UVN LIBS signatures, thus adding robustness to identification procedures. LIBS techniques are more surface specific while NIR spectroscopy has the capability to probe more bulk materials with its greater penetration depth. Both UVN + LWIR LIBS and NIR absorption spectroscopy have shown the capabilities of acquiring useful target analyte spectral signatures in comparable short time scales. The addition of a rapid LWIR spectroscopic probe to these widely used optical analytical methods, such as NIR spectroscopy and UVN LIBS, may greatly enhance the capability and accuracy of the combined system for a comprehensive analysis.

RESUMEN

BACKGROUND: The study was conducted to explore challenges faced by trained informal health providers referring individuals with suspected mental disorders for treatment, and potential opportunities to counter these challenges. METHODS: The study used a qualitative focus group approach. It involved community health workers, traditional and faith healers from Makueni County in Kenya. Ten Focus Group Discussions were conducted in the local language, recorded and transcribed verbatim and translated. Using a thematic analysis approach, data were entered into NVivo 7 for analysis and coding. RESULTS: Results demonstrate that during the initial intake phase, challenges included patients' mistrust of informal health providers and cultural misunderstanding and stigma related to mental illness. Between initial intake and treatment, challenges related to resource barriers, resistance to treatment and limitations of the referral system. Treatment infrastructure issues were reported during the treatment phase. Various suggestions for solving these challenges were made at each phase. CONCLUSIONS: These findings illustrate the commitment of informal health providers who have limited training to a task-sharing model under difficult situations to increase patients' access to mental health services and quality care. With the identified opportunities, the expansion of this type of research has promising implications for rural communities.

RESUMEN

Sonic hedgehog (Shh) signaling influences neurogenesis and neural patterning during the development of central nervous system. Dysregulation of Shh signaling in brain leads to neurological disorders like autism spectrum disorder, depression, dementia, stroke, Parkinson's diseases, Huntington's disease, locomotor deficit, epilepsy, demyelinating disease, neuropathies as well as brain tumors. The synthesis, processing and transport of Shh ligand as well as the localization of its receptors and signal transduction in the central nervous system has been carefully reviewed. Further, we summarize the regulation of small molecule modulators of Shh pathway with potential in neurological disorders. In conclusion, further studies are warranted to demonstrate the potential of positive and negative regulators of the Shh pathway in neurological disorders.

RESUMEN

Diabetes mellitus, a metabolic disorder, is associated with neurological complications such as depression, anxiety, hypolocomotion, cognitive dysfunction, phobias, anorexia, stroke, pain, etc. Traditional system of medicine is long known for its efficient management of diabetes. The current review discusses the scope of some common medicinal herbs as well as secondary metabolites with a special focus on diabetes-mediated central nervous system complications. Literatures suggest that natural products reduce diabetes-mediated neurological complications partly by reducing oxidative stress and/or inflammation or apoptosis in certain brain regions. Natural products are known to modulate diabetes-mediated alterations in the level of acetylcholinesterase, choline acetyltransferase, monoamine oxidase, serotonin receptors, muscarinic receptors, insulin receptor, nerve growth factor, brain-derived neurotrophic factor, and neuropeptide in brain. Further, there are several natural products reported to manage diabetic complications with unknown mechanism. In conclusion, medicinal plants or their secondary metabolites have a wide scope and possess therapeutic potential to effectively manage neurological complications associated with chronic diabetes.

RESUMEN

The present study was aimed to evaluate the effect of Urtica dioica (UD) extract against chronic unpredictable stress (CUS)-induced associative memory dysfunction and attempted to explore the possible mechanism. Male Swiss albino mice (25-30g) were divided into six groups, viz. group-I received 0.3% carboxymethyl cellulose and served as control (CTRL), group II was exposed to CUS (21days) and received vehicle (CUS), group III was subjected to CUS and received Hypericum perforatum extract (350mg/kg, p.o.) (CUS+HYP), group IV received Hypericum perforatum extract (350mg/kg, p.o.) (CTRL+HYP); group V was subjected to CUS and received UD extract (50mg/kg, p.o.) (CUS+UD), group VI received UD extract (50mg/kg, p.o.) (CTRL+UD). CUS significantly induced body weight loss (p<0.05) and associative memory impairment in step down task (p<0.05) as compared to control mice. CUS significantly downregulated Smo (p<0.05), Gli1 (p<0.01), cyclin D1 (p<0.05), BDNF (p<0.01), TrKB (p<0.01) and MAPK1 (p<0.01) mRNA expression in hippocampus as compared to control mice. CUS significantly increased the levels of TBARS (p<0.01) and nitric oxide (p<0.001), and decreased catalase (p<0.001) and total thiol (p<0.01) in plasma resulting in oxidative stress and inflammation. Chronic UD administration significantly reverted CUS mediated body weight loss (p<0.05) and cognitive impairment (p<0.05). UD administration significantly decreased the levels of TBARS (p<0.01) and nitric oxide (p<0.05), and increased the levels of catalase (p<0.01) and total thiol (p<0.05) in plasma. Chronic UD administration significantly upregulated hippocampal Smo (p<0.05), Gli1 (p<0.001), cyclin D1 (p<0.05), BDNF (p<0.05), TrKB (p<0.05) and MAPK1 (p<0.05) in stressed mice. Further, UD extract did not reverse cyclopamine induced downregulation of Gli1 and Ptch1 mRNA in hippocampal slices. UD modulated Smo-Gli1 pathway in the hippocampus as well as exerted anti-inflammatory and antioxidant effects. UD extract might prove to be effective for stress mediated neurological disorders.

RESUMEN

Family stressors predict negative psychological outcomes for immigrant adolescents, yet little is known about how such stressors interact to predict school outcomes. The purpose of this study was to explore the interactive role of family stressors on school outcomes for newcomer adolescent immigrants. Using a convergent parallel mixed-methods design, we used quantitative methods to explore interactions between family separation, acculturative family conflict, and family life events to predict 2 school outcomes, academic achievement (via grade point average [GPA]), and externalizing problems (student- and teacher-reported). The sample included 189 newcomer immigrant public high school students from 34 countries of origin. Quantitative measures included the Multicultural Events Scale for Adolescents, Family Conflicts Scale, and the Achenbach System of Empirically Based Assessment (ASEBA). Qualitative data were collected through a semi-structured interview. Quantitative results found that more family life events were associated with lower GPA, but this association was weaker for participants who had been separated from their parents. More family conflict was associated with more externalizing symptoms (both youth- and teacher-reported). However, the association between family conflict and teacher-reported externalizing symptoms was found only among participants reporting a greater than average number of life events. Qualitative results show that separation from extended family networks was among the most stressful of experiences, and demonstrate the highly complex nature of each family stressor domain. At a time when immigration is rapidly changing our school system, a better understanding of early risk factors for new immigrants can help teachers, administrators, and mental health practitioners to identify students with greatest need to foster behavioral, academic, and emotional well-being.

RESUMEN

Diabetes mellitus has been associated with functional abnormalities in the hippocampus and performance of cognitive function. Urtica dioica (UD) has been used in the treatment of diabetes. In our previous report we observed that UD extract attenuate diabetes mediated associative and spatial memory dysfunction. The present study aimed to evaluate the effect of UD extract on mouse model of diabetes-induced recognition memory deficit and explore the possible mechanism behind it. Streptozotocin (STZ) (50 mg/kg, i.p. consecutively for 5 days) was used to induce diabetes followed by UD extract (50 mg/kg, oral) or rosiglitazone (ROSI) (5 mg/kg, oral) administration for 8 weeks. STZ induced diabetic mice showed significant decrease in hippocampal insulin signaling and translocation of glucose transporter type 4 (GLUT4) to neuronal membrane resulting in cognitive dysfunction and hypolocomotion. UD treatment effectively improved hippocampal insulin signaling, glucose tolerance and recognition memory performance in diabetic mice, which was comparable to ROSI. Further, diabetes mediated oxidative stress and inflammation was reversed by chronic UD or ROSI administration. UD leaves extract acts via insulin signaling pathway and might prove to be effective for the diabetes mediated central nervous system complications.

RESUMEN

Comorbidity of depression and diabetes is a serious risk factor worsening the complications such as cognitive function and locomotion. Treatment under this condition becomes extremely complicated. Insulin signaling and autophagy pathways are involved in modulation of learning and memory. Rosiglitazone (ROSI) ameliorate cognitive deficit associated with depression and insulin resistance. In the present study, we investigated the effect of ROSI against chronic unpredictable stress (CUS) induced depression as a risk factor for diabetes and behavioral dysfunctions. Adult male Swiss albino mice were exposed to CUS alongside ROSI (5mg/kg/day) treatment for 21days. Thereafter, animals were subjected to different behavioral studies to assess depressive like behavior, cognition and locomotion. The effect of ROSI on insulin signaling, autophagy and apoptosis were evaluated in the hippocampus. CUS resulted in depressive like behavior, cognitive impairment and hypolocomotion associated with oxidative stress, impaired glucose tolerance and hypercorticosteronemia. CUS significantly impaired hippocampal insulin signaling, membrane translocation of glucose transporter type 4 (GLUT4) as well as decreased the expression of autophagy5, autophagy7, B-cell lymphoma 2 and apoptosis inhibitory protein 2. ROSI significantly reduced depressive like behavior, postprandial blood glucose, hypercorticosteronemia, oxidative and inflammatory stress, and apoptosis in stressed mice. Moreover, ROSI treatment effectively improved hippocampal insulin signaling, GLUT4 membrane translocation and cognitive performance in depressed mice. ROSI administration might prove to be effective for neurological disorders associated with depressive like behavior and impaired glucose tolerance.

RESUMEN

Diabetes mellitus is a chronic metabolic disorder and has been associated with cognitive dysfunction. In our earlier study, chronic Urtica dioica (UD) treatment significantly ameliorated diabetes induced associative and spatial memory deficit in mice. The present study was designed to explore the effect of UD leaves extract on muscarinic cholinergic system, which has long been known to be involved in cognition. Streptozotocin (STZ) (50 mg/kg, i.p., consecutively for 5 days) was used to induce diabetes followed by treatment with UD extract (50 mg/kg, oral) or rosiglitazone (5 mg/kg, oral) for 8 weeks. STZ-induced diabetic mice showed significant reduction in hippocampal muscarinic acetylcholine receptor-1 and choline acetyltransferase expressions. Chronic diabetes significantly up-regulated the protein expression of acetylcholinesterase associated with oxidative stress in hippocampus. Besides, STZ-induced diabetic mice showed hypolocomotion with up-regulation of muscarinic acetylcholine receptor-4 expression in striatum. Chronic UD treatment significantly attenuated the cholinergic dysfunction and oxidative stress in the hippocampus of diabetic mice. UD had no effect on locomotor activity and muscarinic acetylcholine receptor-4 expression in striatum. In conclusion, UD leaves extract has potential to reverse diabetes mediated alteration in muscarinic cholinergic system in hippocampus and thereby improve memory functions.

RESUMEN

Evidences suggest that glucocorticoids results in depression and is a risk factor for type 2 diabetes. Further diabetes induces oxidative stress and hippocampal dysfunction resulting in cognitive decline. Traditionally Urtica dioica has been used for diabetes mellitus and cognitive dysfunction. The present study investigated the effect of the hydroalcoholic extract of Urtica dioica leaves (50 and 100 mg/kg, p.o.) in dexamethasone (1 mg/kg, i.m.) induced diabetes and its associated complications such as depressive like behavior and cognitive dysfunction. We observed that mice administered with chronic dexamethasone resulted in hypercortisolemia, oxidative stress, depressive like behavior, cognitive impairment, hyperglycemia with reduced body weight, increased water intake and decreased hippocampal glucose transporter-4 (GLUT4) mRNA expression. Urtica dioica significantly reduced hyperglycemia, plasma corticosterone, oxidative stress and depressive like behavior as well as improved associative memory and hippocampal GLUT4 mRNA expression comparable to rosiglitazone (5 mg/kg, p.o.). Further, Urtica dioica insignificantly improved spatial memory and serum insulin. In conclusion, Urtica dioica reversed dexamethasone induced hyperglycemia and its associated complications such as depressive like behavior and cognitive dysfunction.

RESUMEN

BACKGROUND: To meet federal requirements under Title VI of the Civil Rights Act, the state of California instituted policies requiring that comprehensive mental health services in native languages be made available to limited English proficiency (LEP) populations when concentrations exceed "threshold" levels. METHODS: This paper builds on promising results from quantitative evaluations by reporting on qualitative interviews with Latino and Vietnamese LEP clients in mental health services (N = 20) to examine the awareness, impact, and implications of these threshold language policies. RESULTS: Results suggest that, while individuals are often not aware of the policies themselves, the language-related services they receive that are prompted by the policies are critical to treatment initiation and retention. Results also convey the complexities of using interpreters for sensitive psychological topics, and suggest that, for LEP individuals seeking mental health treatment, providers who speak their native languages are generally preferred. CONCLUSIONS: Access to language-appropriate services seems to be an important part of why LEP populations seek mental health treatment. However, there are multiple variables that factor into the usage and usefulness of such services.
