Anxious Activists? Examining Immigration Policy Threat, Political Engagement, and Anxiety among College Students with Different Self/Parental Immigration Statuses.

Restrictive immigration policies harm the mental health of undocumented immigrants and their U.S. citizen family members. As a sociopolitical stressor, threat to family due to immigration policy can heighten anxiety, yet it is unclear whether political engagement helps immigrant-origin students to cope. We used a cross-sectional survey of college students from immigrant families (N = 2,511) to investigate whether anxiety symptomatology was associated with perceived threat to family and if political engagement moderated this relationship. We stratified analyses by self/parental immigration statuses-undocumented students, U.S. citizens with undocumented parents, and U.S. citizens with lawfully present parents-to examine family members' legal vulnerability. Family threat was significantly associated with anxiety; higher levels of political engagement reduced the strength of this relationship. However, this moderation effect was significant only for U.S. citizens with lawfully present parents. These findings emphasize the importance of the family immigration context in shaping individuals' mental health outcomes.

Using symbolic machine learning to assess and model substance transport and decay in water distribution networks.

Drinking water infrastructures are systems of pipes which are generally networked. They play a crucial role in transporting and delivering clean water to people. The water quality analysis refers to the evaluation of the advective diffusion of any substance in drinking water infrastructures from source nodes. Such substances could be a contamination for the system or planned for the disinfection, e.g., chlorine. The water quality analysis is performed by integrating the differential equation in the pipes network domain using the kinetics of the substance decay and the Lagrangian scheme. The kinetics can be formulated using a specific reaction order depending on the substance characteristics. The basis for the integration is the pipes velocity field calculated by means of hydraulic analysis. The aim of the present work is to discover the intrinsic mechanism of the substance transport in drinking water infrastructures, i.e., their pipes network domain, using the symbolic machine learning, named Evolutionary Polynomial Regression, which provides "synthetic" models (symbolic formulas) from data. We demonstrated, using one real network and two test networks, that the concentration at each node of the network can be predicted using the travel time along the shortest path(s) between the source and each node. Additionally, the formula models provided by symbolic machine learning allowed discovering that a unique formula based on kinetic reaction model structure allows predicting the residual substance concentration at each node, given the source node concentration, surrogating with a good accuracy the integration of the differential equations.

Effectiveness of Virtual Reality and Feedback to Improve Gait and Balance in Patients with Diabetic Peripheral Neuropathies: Systematic Review and Meta-Analysis.

Diabetic peripheral neuropathy (DPN) is the primary complication in patients with diabetes mellitus, characterized by loss of sensation and function in the lower limbs. Virtual reality (VR) and/or sensory feedback (FB) therapy has shown positive effects in other neurologic conditions such as stroke. However, consensus regarding their effectiveness in the DPN population is lacking. This study aims to analyze existing scientific evidence about the effects of VR and/or FB on improving gait and balance and reducing the risk of falls in patients with DPN (pwDPN). A thorough search was conducted in scientific databases including PubMed, Scopus, and EMBASE, up until November 2023. CMSQ, the PEDro scale, and the Cochrane Collaboration's tool were used to assess the methodological quality and risk of bias of the studies. A total of 10 studies were selected for qualitative analysis, with three contributing information to the meta-analysis. The combined results suggest a positive trend in favor of VR and FB rehabilitation; however, significant differences were not observed in balance (SMD = -0.81, 95% CI = -1.90, 0.29; p = 0.15; I2 = 86%) or gait speed improvements (MD = -1.05, 95% CI = -2.96, 0.85; p = 0.28; I2 = 89%). Therefore, further randomized controlled studies are still needed to achieve stronger conclusions regarding the benefits of VR and/or FB in pwDPN.

Usefulness of Docking and Molecular Dynamics in Selecting Tumor Neoantigens to Design Personalized Cancer Vaccines: A Proof of Concept.

Personalized cancer vaccines based on neoantigens are a new and promising treatment for cancer; however, there are still multiple unresolved challenges to using this type of immunotherapy. Among these, the effective identification of immunogenic neoantigens stands out, since the in silico tools used generate a significant portion of false positives. Inclusion of molecular simulation techniques can refine the results these tools produce. In this work, we explored docking and molecular dynamics to study the association between the stability of peptide-HLA complexes and their immunogenicity, using as a proof of concept two HLA-A2-restricted neoantigens that were already evaluated in vitro. The results obtained were in accordance with the in vitro immunogenicity, since the immunogenic neoantigen ASTN1 remained bound at both ends to the HLA-A2 molecule. Additionally, molecular dynamic simulation suggests that position 1 of the peptide has a more relevant role in stabilizing the N-terminus than previously proposed. Likewise, the mutations may have a "delocalized" effect on the peptide-HLA interaction, which means that the mutated amino acid influences the intensity of the interactions of distant amino acids of the peptide with the HLA. These findings allow us to propose the inclusion of molecular simulation techniques to improve the identification of neoantigens for cancer vaccines.

Immigration Status, Legal Vulnerability, and Suicidal/Self-harm Ideation Disparities Among Immigrant-Origin Latinx Young Adults in the U.S.

Theories of suicidality typically center intrapersonal processes, with limited attention to social determinants of mental health disparities. Using a legal vulnerability framework, we examined the association between self/parental immigration status and suicidal and self-harm ideation (SI) disparities in three groups of immigrant-origin Latinx young adults attending college in the USA: undocumented students (n = 564), US citizens with undocumented parents (n = 605), and US citizens with lawfully present parents (n = 596). We also evaluated whether self/parental immigration status differences in SI could be accounted for by six dimensions of legal vulnerability and, based on prominent theories of suicidality, explored the role of campus belongingness as a protective factor. Participants completed self-report measures, and SI was assessed using one item from the Patient Health Questionnaire-9, a screening tool that assesses the severity of depression symptomatology. Rates of SI were significantly higher among undocumented students (23.1%) and US citizens with undocumented parents (24.3%) compared to US citizens with lawfully present parents (17.8%). Immigration policy-related social exclusion and discrimination-mediated self/parental immigration status differences in SI. Although food insecurity did not differ by self/parental immigration status, greater food insecurity was associated with higher likelihood of SI. Greater campus belongingness was associated with a lower likelihood of endorsing SI for all students regardless of immigration status or legal vulnerability factors. Findings underscore the importance of examining self and parental immigration status as a social determinant of SI and the value of investigating aspects of legal vulnerability as explanatory factors.

Immigration-Related Discrimination and Mental Health among Latino Undocumented Students and U.S. Citizen Students with Undocumented Parents: A Mixed-Methods Investigation.

Research has consistently linked discrimination and poorer health; however, fewer studies have focused on immigration-related discrimination and mental health outcomes. Drawing on quantitative surveys (N = 1,131) and qualitative interviews (N = 63) with Latino undergraduate students who are undocumented or U.S. citizens with undocumented parents, we examine the association between perceived immigration-related discrimination and mental health outcomes and the process through which they are linked. Regression analyses identify an association between immigration-related discrimination and increased levels of depression and anxiety; this relationship did not vary by self and parental immigration status. Interview data shed light on this result as immigration-related discrimination manifested as individual discrimination as well as vicarious discrimination through family and community members. We contend that immigration-related discrimination is not limited to individual experiences but rather is shared within the family and community, with negative implications for the mental health of undocumented immigrants and mixed-status family members.

Effect of neoadjuvant chemotherapy on tumor immune infiltration in breast cancer patients: Systematic review and meta-analysis.

The tumor immune infiltrate has an impact on cancer control and progression, additionally a growing body of evidence has proposed the role of neoadjuvant chemotherapy in modulating the contexture of the tumor immune infiltrate. Here, we performed a systematic review to evaluate the effect of chemotherapy in the immune infiltration of breast cancer tumors. We systematically searched Pubmed/MEDLINE, EMBASE, CENTRAL, and BVS databases with a cutoff date of 11/06/2022. Studies in patients with pathological diagnosis of BC, whose first line of treatment was only NAC, were included. Only published experimental studies that measured tumor immune infiltrate before and after NAC by hematoxylin and eosin (H&E) staining, immunohistochemistry (IHQ), or transcriptome were included. Reviews, studies with animal models and in-vitro models were excluded. Studies in which BC was not the primary tumor or studies with patients who received other types of neoadjuvant therapy were also excluded. The NIH quality assessment tool for before and after studies without control was used. We included 32 articles that evaluated the proximal tumor microenvironment before and after neoadjuvant chemotherapy in 2072 patients who received NAC as first line of treatment and who were evaluated for immune infiltrate in the pre- and post-chemotherapy tumor sample. Results were divided into two major categories immune cells and in-situ expression of immune checkpoints and cytokines. Qualitative synthesis was performed with the 32 articles included, and in nine of them a quantitative analysis was achieved, resulting in six meta-analyses. Despite high heterogeneity among the articles regarding treatment received, type of tumor reported, and techniques used to evaluate immune infiltrate, we found a significant decrease of TILs and FoxP3 expression after neoadjuvant chemotherapy. The study protocol was registered in PROSPERO 2021 (Protocol ID: CRD42021243784) on 6/29/2021.

Mental Health and COVID-19 Pandemic Stressors Among Latina/o/x College Students with Varying Self and Parental Immigration Status.

The COVID-19 pandemic has produced significant psychological distress for college students due to the sudden proliferation of stressors. We examine whether and how self and parental immigration status contributes to Latina/o/x college students' mental health and pandemic stressors during the initial months of the pandemic. We draw on quantitative and qualitative survey data collected in March-June 2020 with 1,600 Latina/o/x University of California undergraduate students from three self-identified groups: undocumented students, US citizens with at least one undocumented parent, and US citizens with lawfully present parents. Quantitative analyses reveal that the pandemic produced widespread negative mental health effects but the severity of these effects did not differ by self/parental immigration status. Our qualitative analyses identify common pandemic-related stressors across our three student groups (financial insecurity, COVID-19 virus concerns, academic strains, and social dynamics); however, undocumented students and US citizens with undocumented parents identify unique aspects of these stressors due to legal vulnerabilities. Self and parental undocumented status also compromises the ability to manage common pandemic stressors because of immigration status-related exclusion from necessary resources. Ultimately, we argue that the high-stress nature of the pandemic elevated mental distress across all student groups, but the structural exclusion of undocumented immigrants contributes to unique experiences of stress among Latina/o/x undocumented students and US citizen students with undocumented parents.

Mental health help-seeking among Latina/o/x undocumented college students.

OBJECTIVES: Informed by a social-ecological framework, this study nested undocumented students' individual mental health needs within micro-level campus factors and the macro-level immigration policy context to examine how these are associated with undocumented Latina/o/x college students' use of on-campus mental health services. METHOD: A large-scale survey was administered to 1,277 undocumented college students attending 4-year public universities in California. Only Latina/o/x respondents were included in this study (N = 1,181). Fifty percent of students attended a UC system (n = 589). On average, students were 21.84 years old (SE = .15), and most were women (75.3%, n = 890). RESULTS: Greater level of mental health symptoms and perceived mental health need, and greater use of campus-wide resources and undocumented student services predicted greater likelihood of using on-campus mental health services. Greater perceptions of social exclusion due to the immigration policy context predicted lower use of mental health services. CONCLUSIONS: Results indicate that a greater use of resources and an inclusive campus environment, as well as efforts to minimize policy-related feelings of social exclusion, may facilitate undocumented students' professional mental health help-seeking. These findings emphasize the need to take multiple and multi-level ecological factors into account when considering mental health service use, particularly in the case of undocumented immigrants and likely other structurally marginalized groups.

Effects of Wine and Tyrosol on the Lipid Metabolic Profile of Subjects at Risk of Cardiovascular Disease: Potential Cardioprotective Role of Ceramides.

Ceramides are a class of sphingolipids which have recently been shown to be better cardiovascular disease (CVD) risk predictors than traditional CVD risk biomarkers. Tyrosol (TYR) is a dietary phenolic compound known to possess cardioprotective effects per se or through its in vivo active metabolite hydroxytyrosol. The purpose of this study was to evaluate the effects of the co-administration of white wine (WW) and TYR on circulating levels of ceramides and other lipids in humans at high CVD risk. Volunteers underwent a randomized controlled crossover clinical trial (4-week duration per intervention) with three different interventions: control, WW, and WW enriched with a capsule of TYR (WW + TYR). Endothelial function cardiovascular biomarkers and plasma lipidomic profile were assessed before and after each intervention. It was found that the WW + TYR intervention resulted in lower levels of three ceramide ratios, associated with an improvement of endothelial function (Cer C16:0/Cer C24:0, Cer C18:0/Cer C24:0, and Cer C24:1/Cer C24:0), when compared to the control intervention. Moreover, WW + TYR was able to minimize the alterations in plasma diacylglycerols concentrations observed following WW. Overall, the results obtained show that the antioxidant TYR administered with WW exerts beneficial effects at the cardiovascular level, in part by modulating blood lipid profile.

Influencia de la autoestima, la ansiedad-rasgo y la calidad del sueño en la satisfacción con la vida de los estudiantes de Enfermería / Impact of self-esteem, trait anxiety and quality of sleep on the satisfaction with life in Nursing students

Objetivo: determinar si la autoestima, ansiedad-rasgo y la calidad del sueño constituyen predictores de la satisfacción con la vida en estudiantes de Enfermería.Método: estudio descriptivo transversal y cuantitativo llevado a cabo en estudiantes de Enfermería de la Universidad Católica de Valencia (n= 720), que respondieron a una serie de cuestionarios validados en noviembre de 2014. Se realizaron análisis descriptivos, pruebas de correlación y un modelo de regresión lineal para analizar la influencia de las variables independientes (autoestima, ansiedad-rasgo y calidad del sueño) sobre la variable dependiente (satisfacción con la vida). Se consideró significativa la diferencia si p< 0,05.Resultados: participaron 494 (68,6%) estudiantes. El 77,7% (n= 384) fue mujer. Se observaron diferencias estadísticamente significativas en la satisfacción con la vida y el género (p= 0,002), con valores más altos para las mujeres; en la ansiedad-rasgo respecto al género (p= 0,001), con valores más altos en las mujeres; y en la autoestima respecto al curso del estudiante (p< 0,001), con valores más altos para los alumnos de tercero. Los resultados de la regresión indicaron que el 26,9% (p< 0,01) de la varianza de la satisfacción con la vida es explicada por las tres variables independientes: autoestima, ansiedad-rasgo y satisfacción con el sueño.Conclusiones: el estudio revela que bajas puntuaciones en ansiedad-rasgo y calidad del sueño y altas puntuaciones en autoestima fueron predictores de la satisfacción con la vida. Dada la naturaleza psicógena de dichas variables se discute la necesidad de equipos de atención psicológica en las facultades de Enfermería.(AU)

Physical and mental health impacts of the COVID-19 pandemic among college students who are undocumented or have undocumented parents.

BACKGROUND: The COVID-19 pandemic may have disproportionately affected the mental and physical health of undocumented students and students with undocumented parents. METHODS: We analyzed primary data from 2111 California college students collected March-June 2020. We estimated the odds of mental or physical health being affected "a great deal" by COVID by immigration group and then examined whether this was moderated by campus belonging or resource use. RESULTS: Students with undocumented parents were least likely to report COVID-related mental and physical health effects. Undocumented students and students whose parents have lawful immigration status did not differ in their COVID-related physical and mental health. For all students, more campus resource use and higher campus belonging were associated with negative mental and physical health effects. DISCUSSION: Negative COVID-related mental and physical health was widespread. Separation from campus-based resources was detrimental during the early stages of the pandemic.

Human immune response to SARS-CoV-2: What is known? A scoping review / Respuesta inmune humana al SARS-CoV-2: ¿Qué se conoce? Una scoping review

Monitoring literature on the broad spectrum of the human immune response to SARS-CoV-2 is important to understand the mechanisms and progression of COVID-19. The present study undertakes a scoping review of the literature on human immune response to SARS-CoV-2 to determine the characteristics of innate and adaptive responses, as well as biomarkers and cells that play a role in the development of the infection. We searched papers in MEDLINE/PUBMED and EMBASE databases published since December 1st 2019 to to April 9th 2020 from which we selected 56 for this study. We found that the immune response is characterized by high levels of acute phase reactants, neutrophilia, low levels of NKs and eosinophils, lymphopenia, cytokine storm syndrome, exhausted T cells, impaired cytotoxic response, inadequate helper response and production of specific antibodies; concluding that immune dysregulation correlates with disease severity and high mortality.

El seguimiento de la literatura sobre la respuesta inmune humana al SARS-CoV-2 es importante para comprender los mecanismos y la progresión de COVID-19. En el presente estudio se realizó un Scoping Review de la literatura sobre la respuesta inmune humana al SARS-CoV-2 para determinar las características de la respuesta inmune innata y adaptativa, así como biomarcadores y células que juegan un papel en el desarrollo de la infección. Buscamos artículos en las bases de datos MEDLINE / PUBMED y EMBASE publicados desde el 1 de diciembre de 2019 hasta el 9 de abril de 2020, de los cuales seleccionamos 56 publicaciones para este estudio. Encontramos que la respuesta inmune se caracteriza por altos niveles de reactantes de fase aguda, neutrofilia, bajos niveles de NKs y eosinófilos, linfopenia, síndrome de tormenta de citoquinas, linfocitos T agotados, respuesta citotóxica alterada, respuesta T helper inadecuada y producción de anticuerpos específicos. En conclusión, el desequilibrio inmune se correlaciona con la severidad y la mortalidad de la enfermedad.

A role of the frontotemporal lobar degeneration risk factor TMEM106B in myelination.

TMEM106B encodes a lysosomal membrane protein and was initially identified as a risk factor for frontotemporal lobar degeneration. Recently, a dominant D252N mutation in TMEM106B was shown to cause hypomyelinating leukodystrophy. However, how TMEM106B regulates myelination is still unclear. Here we show that TMEM106B is expressed and localized to the lysosome compartment in oligodendrocytes. TMEM106B deficiency in mice results in myelination defects with a significant reduction of protein levels of proteolipid protein (PLP) and myelin oligodendrocyte glycoprotein (MOG), the membrane proteins found in the myelin sheath. The levels of many lysosome proteins are significantly decreased in the TMEM106B-deficient Oli-neu oligodendroglial precursor cell line. TMEM106B physically interacts with the lysosomal protease cathepsin D and is required to maintain proper cathepsin D levels in oligodendrocytes. Furthermore, we found that TMEM106B deficiency results in lysosome clustering in the perinuclear region and a decrease in lysosome exocytosis and cell surface PLP levels. Moreover, we found that the D252N mutation abolished lysosome enlargement and lysosome acidification induced by wild-type TMEM106B overexpression. Instead, it stimulates lysosome clustering near the nucleus as seen in TMEM106B-deficient cells. Our results support that TMEM106B regulates myelination through modulation of lysosome function in oligodendrocytes.

Immunosenescence Study of T Cells: A Systematic Review.

Background: Aging is accompanied by alterations in immune response which leads to increased susceptibility to infectious diseases, cancer, autoimmunity, and inflammatory disorders. This decline in immune function is termed as immunosenescence; however, the mechanisms are not fully elucidated. Experimental approaches of adaptive immunity, particularly for T cells, have been the main focus of immunosenescence research. This systematic review evaluates and discusses T cell markers implicated in immunosenescence. Objective: To determine the best flow cytometry markers of circulating T cells associated with immunosenescence. Methods: We systematically queried PubMed, MEDLINE, EBSCO, and BVS databases for original articles focused on two age groups of healthy humans: 18-44 (young adults) and >60 (older adults) years. In accordance with the Cochrane methodology, we synthesized data through qualitative descriptions and quantitative random effects meta-analysis due to extensive heterogeneity. Results: A total of 36 studies conducted in the last 20 years were included for the qualitative analysis and four out of these studies were used to perform the meta-analysis. A significant decrease in naïve T cell subset was observed in older adults compared to young adults. Primary markers used to identify senescent cells were loss of CD28 and increased expression of CD57 and KLRG1 in terminally-differentiated memory T cell subset in older adults. Moreover, we observed an increase in proinflammatory cytokines and decrease in telomere length in old adult T cells. It was not possible to perform quantitative synthesis on cell markers, cytokines, and telomere length because of the significant variations between the groups, which is attributed to differences in protocols and unreported measurements, thus generating a high risk of bias. Conclusions: Heterogeneity among studies in terms of data report, measurement techniques and high risk of bias were major impediments for performing a robust statistical analysis that could aid the identification of eligible flow cytometry markers of immunosenescence phenotype in T cells.

Beyond access: Psychosocial barriers to undocumented students' use of mental health services.

RATIONALE: Little is known about how undocumented immigrants navigate healthcare utilization issues apart from access. OBJECTIVE: We examine a unique population of undocumented immigrants who have access to healthcare - college students at the University of California - to identify how immigration status hinders mental health service utilization in the absence of barriers related to eligibility and insurance coverage. METHOD: We conducted semistructured interviews between March and July 2017 with 30 undocumented students at a University of California campus. RESULTS: We argue that undocumented immigration status informs mental health-related illness cognitions to negatively affect students' ability to assess their own mental health and need for services. Students expressed low perceived need because they normalized mental strain as a natural product of their unstable immigration status. Many viewed treatment as futile because it could not address underlying immigration-related issues. They also anticipated stigmas associated with mental illness as well as their own undocumented status. CONCLUSION: Solutions to address utilization disparities must go beyond eliminating formal barriers to health access and address such psychosocial barriers, as well as the larger political and social context that produces them.

Methods to detect antifibrillarin antibodies in patients with systemic sclerosis (SSc): a comparison.

Autoantibodies against nucleolar antigens are common in systemic sclerosis (SSc). They include autoantibodies against fibrillarin (Fb), which are serological markers for SSc. Fb is associated with the evolutionally-conserved box C/D of small nucleolar RNAs (snoRNAs). We compared indirect immunofluorescence (IIF), Western blot (WB), and immunoprecipitation (IPP) of total small RNAs assays to determine which of these techniques is most specific for the detection of snoRNPs. We also examined the frequency and specificity of autoantibodies from SSc patients to snoRNAs, snRNAs, and scRNAs, and concluded that 1) IIF can not determine autoantibody specificity against Fb, 2) 36% of SSc sera were false-negative by WB, and 3) by IPP, anti-Fb autoantibodies from SSc patients can bind U3, U8, U13, U15, and U22 snoRNAs.

Efecto inhibitorio de la endocitosis en leucocitos polimorfonucleares causado por talidomida / Inhibitory effect of endocytosis in polimophonuclear celis caused by thalidomide

La talidomida es un medicamento útil para el tratamiento de la lepra lepromatosa reaccional y se conoce parcialmente su mecanismo de acción. Para entender mejor las propiedades de este fármaco se estudió la función fagocítica de los polimorfonucleares en presencia de talidomida. Los resultados indican que este fármaco disminuye de manera significativa la fagocitosis in vitro y, probablemente mediante el mismo mecanismo, ayuda a disminuir el proceso inflamatorio de la reacción leprosa y otras enfermedades inflamatorias de la piel
