Comparison of the Stress and Anxiety to Viral Epidemic-9 and SAVE-6 scales among healthcare workers in Peru.

Introduction: Peru is a country that has a high incidence of viral outbreaks and epidemics, which is why it is necessary to validate a scale that measures anxiety and stress in professionals who are on the front lines of these events. Therefore, our objective was to validate the Peruvian-Spanish version of the Stress and Anxiety to Viral Epidemics-9 items (SAVE-9) scale and to concurrently compare its validity and internal consistency with the SAVE-6 scale among healthcare workers (HCWs). Materials and methods: We conducted a cross-sectional study based on data collected from a self-reported survey in paper-and-pencil format between April and July 2023. A total of 203 HCWs participated in the research. We developed a confirmatory factor analysis (CFA) and item response theory (IRT). We calculated Cronbach's α coefficient and McDonald's ω to assess the internal consistency of the scales. Results: The results show that SAVE-9 (a two-factor model) and SAVE-6 (a one-factor model) provided an excellent fit in the confirmatory factor analysis. Both scales demonstrated strong internal consistency (Cronbach's α 0.85 and 0.86, respectively). Significant correlations were found between the SAVE-9 and SAVE-6 scales and Generalized Anxiety Disorder-7 items scale (r = 0.44 and r = 0.38, respectively, p < 0.001) as well as the Patient Health Questionnaire-9 items (r = 0.39 and r = 0.35, respectively, p < 0.001). The optimal cutoff points for SAVE-9 and SAVE-6 were identified for assessing anxiety, aligned with a GAD-7 score ≥5 points. Conclusion: The Peruvian-Spanish SAVE-9 and SAVE-6 scales are reliable and valid rating scales to assess the anxiety response of HCWs in response to viral epidemics. Though COVID-19 is diminished, these scales will be useful for other viral epidemics in the future.

Simultaneous Detection of Carbon Quantum Dots as Tracers for Interwell Connectivity Evaluation in a Pattern with Two Injection Wells.

This study aimed to develop and implement a nanotechnology-based alternative to traditional tracers used in the oil and gas industry for assessing interwell connectivity. A simple and rapid hydrothermal protocol for synthesizing carbon quantum dots (CQDs) using agroindustry waste was implemented. Three commercial CQDs were employed (CQDblue, CQDgreen, and CQDred); the fourth was synthesized from orange peel (CQDop). The CQDs from waste and other commercials with spherical morphology, nanometric sizes less than 11 nm in diameter, and surface roughness less than 3.1 nm were used. These tracers demonstrated high colloidal stability with a negative zeta potential, containing carbonyl-type chemical groups and unsaturations in aromatic structures that influenced their optical behavior. All materials presented high colloidal stability with negative values of charge z potential between -17.8 and -49.1. Additionally, individual quantification of these tracers is feasible even in scenarios where multiple CQDs are present in the effluent with a maximum percentage of interference of 15.5% for CQDop in the presence of the other three nanotracers. The CQDs were injected into the field once the technology was insured under laboratory conditions. Monitoring the effluents allowed the determination of connectivity for five first-line producer wells. This study enables the application of CQDs in the industry, particularly in fields where the arrangement of injector and producer wells is intricate, requiring the use of multiple tracers for a comprehensive description of the system.

[Lights and shadows in the implementation of community action for health]. / Luces y sombras en la implementación de la acción comunitaria para la salud.

OBJECTIVE: To explore the experiences of individuals who develop projects and interventions where community participation-action constitutes a strategic tool for reducing health inequalities. METHOD: Qualitative study based on semi-structured, in-depth online interviews with individuals considered experts in the development of health promotion strategies involving community participation. A total of 12 individuals from the healthcare, social healthcare, academic, and associative backgrounds were selected. The texts were analyzed following the thematic content analysis approach. RESULTS: The prominent strength of the processes involving the interviewed individuals is their participatory approach. However, there is no genuine commitment to promoting community participation from primary healthcare, and precarity has been identified as a significant weakness in the development of participatory health promotion projects. The sustainability of participatory processes relies on the transfer of knowledge to the community and their empowerment. CONCLUSIONS: Participatory processes have demonstrated their ability to reposition the community as an essential part of the healthcare system. It would be interesting to use a measurement tool for participation in all community health actions, both to guide their design and planning and to assess the depth of participation and its impact on the process. Enhancing community action expectations for health in the near future involves promoting a community-oriented approach in primary care and intersectoral collaboration, which requires a significant institutional and policy commitment.

A Qualitative Exploration of Spanish-Speaking Latina Women's Experiences Participating in WIC Before and During the COVID-19 Pandemic.

BACKGROUND: More than one-third of the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) participants identify as Latino, but participation has been declining and individuals who speak predominantly Spanish face additional barriers to participation. During the COVID-19 pandemic, there were changes in WIC eligibility and benefits that may have been differentially accessible to Spanish-speaking Latina participants due to factors such as language barriers and lack of awareness of changes. Understanding Spanish-speaking Latinas' experiences with the WIC program generally and during the pandemic can inform efforts to equitably implement future emergency food response policies and improve the WIC program and Latina participant enrollment more broadly. OBJECTIVE: This study aimed to understand the perceptions and experiences of Spanish-speaking Latina WIC participants with the WIC program generally and with COVID-19 pandemic-related policy changes made to the WIC program. DESIGN: Qualitative in-depth interviews were conducted virtually in Spanish in August 2022 using a semi-structured guide. PARTICIPANTS/SETTING: Study participants were 18 Spanish-speaking Latina adult WIC participants living in North Carolina recruited using convenience sampling. ANALYSIS: All interviews were recorded, transcribed, and coded in Spanish. Thematic analysis with inductive coding was used to derive key themes. RESULTS: Perceptions about the WIC program in this sample were mixed. Participants felt positively about the healthfulness of foods included in the WIC food packages but expressed concern about the monthly benefit amounts being too low and the cultural appropriateness of food options. Pandemic policy changes, such as remote appointments and the Cash Value Benefit increase were perceived positively; however, barriers to using benefits during this time included limited communication from WIC agencies, food shortages, and concerns about not being granted US citizenship or permanent resident status due to use of WIC (ie, public charge rule). Social networks played an important role in learning about and enrolling in WIC and navigating food shortages during the pandemic. CONCLUSIONS: Concerns about the cultural appropriateness of foods provided, communication challenges, and the public charge rule emphasized the need for resources dedicated in the WIC program to improving Spanish-speaking Latina women's experiences with WIC.

Epilepsy Care in Latin America and the Caribbean: Overcoming Challenges and Embracing Opportunities.

The burden of epilepsy in the Latin America and the Caribbean (LAC) region causes a profound regional impact on the health care system and significantly contributes to the global epilepsy burden. As in many other resource-limited settings worldwide, health care professionals and patients with epilepsy in LAC countries face profound challenges due to a combination of factors, including high disease prevalence, stigmatization of epilepsy, disparities in access to care, limited resources, substantial treatment gaps, insufficient training opportunities for health care providers, and a diverse patient population with varying needs. This article presents an overview of the epidemiology of epilepsy and discusses the principal obstacles to epilepsy care and key contributors to the epilepsy diagnosis and treatment gap in the LAC region. We conclude by highlighting various initiatives across different LAC countries to improve epilepsy care in marginalized communities, listing strategies to mitigate treatment gaps and facilitate better health care access for patients with epilepsy by enhancing the epilepsy workforce.

Next-generation treatments: Immunotherapy and advanced therapies for COVID-19.

The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in 2019 following prior outbreaks of coronaviruses like SARS and MERS in recent decades, underscoring their high potential of infectivity in humans. Insights from previous outbreaks of SARS and MERS have played a significant role in developing effective strategies to mitigate the global impact of SARS-CoV-2. As of January 7, 2024, there have been 774,075,242 confirmed cases of COVID-19 worldwide. To date, 13.59 billion vaccine doses have been administered, and there have been 7,012,986 documented fatalities (https://www.who.int/) Despite significant progress in addressing the COVID-19 pandemic, the rapid evolution of SARS-CoV-2 challenges human defenses, presenting ongoing global challenges. The emergence of new SARS-CoV-2 lineages, shaped by mutation and recombination processes, has led to successive waves of infections. This scenario reveals the need for next-generation vaccines as a crucial requirement for ensuring ongoing protection against SARS-CoV-2. This demand calls for formulations that trigger a robust adaptive immune response without leading the acute inflammation linked with the infection. Key mutations detected in the Spike protein, a critical target for neutralizing antibodies and vaccine design -specifically within the Receptor Binding Domain region of Omicron variant lineages (B.1.1.529), currently dominant worldwide, have intensified concerns due to their association with immunity evasion from prior vaccinations and infections. As the world deals with this evolving threat, the narrative extends to the realm of emerging variants, each displaying new mutations with implications that remain largely misunderstood. Notably, the JN.1 Omicron lineage is gaining global prevalence, and early findings suggest it stands among the immune-evading variants, a characteristic attributed to its mutation L455S. Moreover, the detrimental consequences of the novel emergence of SARS-CoV-2 lineages bear a particularly critical impact on immunocompromised individuals and older adults. Immunocompromised individuals face challenges such as suboptimal responses to COVID-19 vaccines, rendering them more susceptible to severe disease. Similarly, older adults have an increased risk of severe disease and the presence of comorbid conditions, find themselves at a heightened vulnerability to develop COVID-19 disease. Thus, recognizing these intricate factors is crucial for effectively tailoring public health strategies to protect these vulnerable populations. In this context, this review aims to describe, analyze, and discuss the current progress of the next-generation treatments encompassing immunotherapeutic approaches and advanced therapies emerging as complements that will offer solutions to counter the disadvantages of the existing options. Preliminary outcomes show that these strategies target the virus and address the immunomodulatory responses associated with COVID-19. Furthermore, the capacity to promote tissue repair has been demonstrated, which can be particularly noteworthy for immunocompromised individuals who stand as vulnerable actors in the global landscape of coronavirus infections. The emerging next-generation treatments possess broader potential, offering protection against a wide range of variants and enhancing the ability to counter the impact of the constant evolution of the virus. Furthermore, advanced therapies are projected as potential treatment alternatives for managing Chronic Post-COVID-19 syndromeand addressing its associated long-term complications.

Rescue and rehabilitation of maned wolf (Chrysocyon brachyurus) in Paraguay: Case description.

The maned wolf, Chrysocyon brachyurus, is the largest South American canid, with a natural distribution that stretches across Peru, Bolivia, Brazil, Argentina, Paraguay and Uruguay. The present study reports the case of a rescued specimen of maned wolf that underwent a rehabilitation process in Paraguay, starting in October 2020 with its rescue, and finalising in May 2021 with the reintroduction. Herein, we document findings regarding the general management, biometrics, feeding and environmental enrichment; chemical immobilisation and monitoring; haematology, blood biochemistry and specific serology-relevant pathogens; skin examination and bone marrow cytology; orthopaedic, ophthalmological and dental evaluation; abdominal and cardiac ultrasonography; radiology and copro-parasitology. Main findings include the feeding habits of the individual and enrichment opportunities. The animal weighed 7 kg on arrival, with an estimated age of 5 months, and 18 kg on reintroduction, with an estimated age of 1 year. The animal tested negative to serologic tests for Brucella canis, Dirofilaria, canine distemper, Toxoplasmosis and canine parvovirus. Leptospira testing showed antibodies against L. grippotyphosa on both samplings, L. wolffi and L. ictero on the first sampling, and L. pomona on the second sampling. Abdominal organs were examined and measured through ultrasound evaluation and kidneys showed no alterations. Echocardiography showed preserved mitral, tricuspid and aortic valve flows, but turbulent pulmonary valve flow. Copro-parasitology reported the presence of Lagochilascaris sp. and Balantidium sp. All the information gathered aided in diagnosing the health status of the individual, and the response to environmental enrichment helped assess the behaviour, which led to the suggestion of reintroducing the animal. These data constitute the first published health check of a maned wolf in Paraguay, which can contribute to the species' conservation in the country. The protocol presented in this study can serve as a basis for developing an action plan for the maned wolf in Paraguay.

Design of AsLOV2 domain as a carrier of light-induced dissociable FMN photosensitizer.

Flavin mononucleotide (FMN) is a highly efficient photosensitizer (PS) yielding singlet oxygen (1 O2 ). However, its 1 O2 production efficiency significantly decreases upon isoalloxazine ring encapsulation into the protein matrix in genetically encoded photosensitizers (GEPS). Reducing isoalloxazine ring interactions with surrounding amino acids by protein engineering may increase 1 O2 production efficiency GEPS, but at the same time weakened native FMN-protein interactions may cause undesirable FMN dissociation. Here, in contrast, we intentionally induce the FMN release by light-triggered sulfur oxidation of strategically placed cysteines (oxidation-prone amino acids) in the isoalloxazine-binding site due to significantly increased volume of the cysteinyl side residue(s). As a proof of concept, in three variants of the LOV2 domain of Avena sativa (AsLOV2), namely V416C, T418C, and V416C/T418C, the effective 1 O2 production strongly correlated with the efficiency of irradiation-induced FMN dissociation (wild type (WT) < V416C < T418C < V416C/T418C). This alternative approach enables us: (i) to overcome the low 1 O2 production efficiency of flavin-based GEPSs without affecting native isoalloxazine ring-protein interactions and (ii) to utilize AsLOV2, due to its inherent binding propensity to FMN, as a PS vehicle, which is released at a target by light irradiation.

Bovine Peripheral Blood-Derived Mesenchymal Stem Cells (PB-MSCs) and Spermatogonial Stem Cells (SSCs) Display Contrasting Expression Patterns of Pluripotency and Germ Cell Markers under the Effect of Sertoli Cell Conditioned Medium.

In vitro gamete derivation has been proposed as an interesting strategy for treatment of infertility, improvement of genetic traits, and conservation of endangered animals. Spermatogonial stem cells (SSCs) are primary candidates for in vitro gamete derivation; however, recently, mesenchymal stem cells (MSCs) have also been proposed as candidates for germ cell (GCs) differentiation mainly due to their transdifferentiating capacity. The objective of the present study was to compare the potential for GC differentiation of bovine peripheral blood-derived MSCs (PB-MSCs) and SSCs under the effect of conditioned medium (CM) derived from Sertoli cells (SCs/CM). Samples were collected every 7 days for 21 days and analyzed for pluripotent, GC, and MSC marker expression. The absence of OCT4 and the increased (p < 0.05) expression of NANOG seems to play a role in SSC differentiation, whereas the absence of NANOG and the increased expression (p < 0.05) of OCT4 may be required for PB-MSC differentiation into GCs. SSCs cultured with SCs/CM increased (p < 0.05) the expression of PIWIL2 and DAZL, while PB-MSCs cultured under the same condition only increased (p < 0.05) the expression of DAZL. Overall, the patterns of markers expression suggest that PB-MSCs and SSCs activate different signaling pathways after exposure to SCs/CM and during differentiation into GCs.

The impact of the COVID-19 pandemic on nursing home professionals: results of the RESICOVID project.

OBJECTIVES: The situation caused by the COVID-19 pandemic has had an impact on the mental, physical, and social health of nursing home staff. The operations and protocols of long-term care facilities had to be adapted to a new, unforeseen, and unknown situation in which a devastating and highly contagious disease was causing large numbers of deaths. The aim of this study was to determine the cumulative impact of the COVID-19 pandemic on care, technical, coordinating-supervisory, and managerial staff working in nursing homes. METHODS: Correlation analysis and between-group comparisons were carried out to study the relationship between burnout scores, emotional balance, and organic and behavioral symptoms. RESULTS: The results indicate high levels of burnout and psychological exhaustion. Management professionals displayed higher levels of organic and behavioral symptoms than other professional categories in the same care settings. Despite this negative symptomatology, most professionals showed a positive emotional balance. CONCLUSION: The need to develop intervention programs to improve the mental, physical, and occupational health of the staff in nursing homes, considering the needs of different professional categories, is emphasized.

Evidence of epigenetic landscape shifts in mucopolysaccharidosis IIIB and IVA.

Lysosomal storage diseases (LSDs) are a group of monogenic diseases characterized by mutations in genes coding for proteins associated with the lysosomal function. Despite the monogenic nature, LSDs patients exhibit variable and heterogeneous clinical manifestations, prompting investigations into epigenetic factors underlying this phenotypic diversity. In this study, we focused on the potential role of epigenetic mechanisms in the pathogenesis of mucopolysaccharidosis IIIB (MPS IIIB) and mucopolysaccharidosis IVA (MPS IVA). We analyzed DNA methylation (5mC) and histone modifications (H3K14 acetylation and H3K9 trimethylation) in MPS IIIB and MPS IVA patients' fibroblasts and healthy controls. The findings revealed that global DNA hypomethylation is present in cell lines for both diseases. At the same time, histone acetylation was increased in MPS IIIB and MPS IVA cells in a donor-dependent way, further indicating a shift towards relaxed open chromatin in these MPS. Finally, the constitutive heterochromatin marker, histone H3K9 trimethylation, only showed reduced clustering in MPS IIIB cells, suggesting limited alterations in heterochromatin organization. These findings collectively emphasize the significance of epigenetic mechanisms in modulating the phenotypic variations observed in LSDs. While global DNA hypomethylation could contribute to the MPS pathogenesis, the study also highlights individual-specific epigenetic responses that might contribute to phenotypic heterogeneity. Further research into the specific genes and pathways affected by these epigenetic changes could provide insights into potential therapeutic interventions for these MPS and other LSDs.

A close-up view of the Hunter syndrome.

The Lysosomal Storage disease known as Mucopolysaccharidosis type II, is caused by mutations affecting the iduronate-2-sulfatase required for heparan and dermatan sulfate catabolism. The central nervous system (CNS) is mostly and severely affected by the accumulation of both substrates. The complexity of the CNS damage observed in MPS II patients has been limitedly explored. The use of mass spectrometry (MS)-based proteomics tools to identify protein profiles may yield valuable information about the pathological mechanisms of Hunter syndrome. In this further study, we provide a new comparative proteomic analysis of MPS II models by using a pipeline consisting of the identification of native protein complexes positioned selectively by using a specific antibody, coupled with mass spectrometry analysis, allowing us to identify changes involving in a significant number of new biological functions, including a specific brain antioxidant response, a down-regulated autophagic, the suppression of sulfur catabolic process, a prominent liver immune response and the stimulation of phagocytosis among others.

Factors Associated with HIV Testing Among Spanish and English-Speaking Latino Adolescents Aged 13-18.

Adolescent Latino men who have sex with men (LMSM) in the U.S. are disproportionately impacted by HIV. However, there has been limited focus on their HIV prevention and risk behaviors. In this study, we examine the rates of HIV testing and explore the significant demographic and healthcare factors that influence HIV prevention among adolescent LMSM. The analysis for this study utilized data collected during the baseline assessment of SMART, a pragmatic trial aimed at evaluating the effectiveness of an online HIV prevention intervention for adolescent LMSM (N = 524). Only 35.5% of participants had ever had an HIV test in their lifetime. Rates of testing increased among adolescent LMSM who had a doctor with whom they spoke about their sexual health (odds ratio: 4.0; 95% confidence interval: 2.1-8.4; P < 0.001) or HIV testing (odds ratio: 5.8; 95% confidence interval: 3.1-10.7; P < 0.001). Out of the 61 participants who took part in the survey conducted in Spanish, only 26% reported ever having an HIV test. Additionally, 24.5% stated that they had discussed their sexual orientation with a doctor, and only 8.2% had undergone HIV testing. Spanish-speaking adolescents who completed the SMART survey were less likely to openly discuss their sexual orientation or sexual health with most people or have a doctor with whom they discussed these topics, compared to those who completed the survey in English. These findings suggest that Spanish-speaking adolescent LMSM may face obstacles in accessing HIV prevention services in the U.S.

RESUMEN: Los adolescentes latinos hombres que tienen sexo con otros hombres (LHSH) tienen mayor probabilidad de recibir tratamiento para el VIH más tarde en comparación con todos los casos nuevos del VIH en los Estados Unidos. Sin embargo, se ha estudiado muy poco sus prácticas de prevención de VIH o prácticas de riesgo, que similar a la de jóvenes no latinos, es determinada por múltiples factores. En este estudio describimos las tasas de pruebas para el VIH e identificamos los factores lingüísticos, individuales, familiares, escolares y de cuidado de salud que influencian a los adolescentes LHSH. Los datos provinieron de la evaluación inicial para SMART, un ensayo práctico de una intervención en línea para prevenir el VIH entre adolescentes LHSH (N = 524). Las medidas incluían la experiencia de hacerse la prueba del VIH a lo largo de la vida, factores de aculturación, datos demográficos, prácticas sexuales, educación sobre el VIH en la escuela y el hogar, comunicación sobre salud sexual con los médicos, conocimiento sobre el VIH y actitudes de riesgo. Solo 35.5% de los participantes se han realizado la prueba de VIH al menos una vez en su vida. La tasa de pruebas del VIH fue más alta entre los adolescentes LHSH que indicaron haber hablado con su médico sobre su salud sexual (odds ratio: 4.0; intervalo de confianza del 95%: 2.1­8.4; P < 0.001) o de la prueba del VIH (odds ratio: 5.8; intervalo de confianza del 95%: 3.1­10.7; P < 0.001). Más de 60 participantes completaron la encuesta en español. De estos, pocos reportaron alguna vez haberse hecho la prueba del HIV (26%), tener un médico con quien hablar sobre su orientación sexual (24.5%) o hablar sobre la prueba del VIH (8.2%). Estas cifras son significativamente más bajas que las obtenidas en la encuesta en inglés. Este estudio es uno de los primeros en evaluar los factores para hacerse la prueba del VIH entre adolescentes latinos que hablan inglés y español con edades entre 13 y 18 años. Los adolescentes latinos que completaron SMART en español tuvieron menos probabilidad de haber compartido sobre su orientación sexual con la mayoría de las personas o tener un médico con quien hablar sobre su orientación sexual o su salud sexual, en comparación con aquellos que completaron SMART en inglés, lo que sugiere que los jóvenes latinos que prefieren comunicarse en español pueden experimentar mayores barreras para acceder a los servicios de prevención del VIH en los Estados Unidos.

Abatacept in usual and in non-specific interstitial pneumonia associated with rheumatoid arthritis.

OBJECTIVE: To compare the effectiveness of abatacept (ABA) in Rheumatoid Arthritis-associated Interstitial Lung Disease (RA-ILD) according to the radiological patterns of usual (UIP) or non-specific interstitial pneumonia (NSIP). METHODS: From an observational longitudinal multicentre study of 263 RA-ILD patients treated with ABA, those with UIP or NSIP were selected. Lung function, chest high resolution computerised tomography (HRCT) and dyspnoea were recorded and compared in both groups from baseline to the end of follow-up (progression definitions: improvement or worsening >10% of FVC or DLCO, changes in HRCT extension and 1-point change in the mMRC scale, respectively). Differences between final and baseline visits were calculated as the average difference (95% CI) through mixed effects models regression. RESULTS: We studied 190 patients with UIP (n=106) and NSIP (n=84). General features were similar in both groups except for older age, positive rheumatoid factor, and previous sulfasalazine therapy, which were more frequent in patients with UIP. ILD duration up to ABA initiation was relatively short: median 16 [4-50] and 11 [2-36] months (p=0.36) in UIP and NSIP, respectively. Mean baseline FVC and DLCO were 82% and 63% in UIP and 89% and 65% in NSIP, respectively. Both parameters remained stable during 24 months with ABA. HRCT lesions and dyspnoea improved/stabilized in 73.1% and 90.5% and 72.9% and 94.6% of UIP and NSIP patterns, respectively. CONCLUSION: ABA seems equally effective in stabilizing dyspnoea, lung function and radiological impairment in both UIP and NSIP patterns of RA-ILD. Early administration of ABA may prevent RA-ILD progression, regardless of the radiological pattern.

Experiences of Latinx sexual and gender minorities with access to healthcare during COVID-19 stay-at-home orders.

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic affected all social systems, but healthcare services were particularly disrupted. The pandemic also had a disproportionate impact on populations made socially vulnerable. In this study, we documented the experiences of Latinx sexual and gender minority (SGM) individuals with access to care during COVID-19 stay-at-home orders. METHODS: Semistructured qualitative interviews assessing experiences during the stay-at-home orders in response to the COVID-19 pandemic and patients' experiences accessing healthcare during this period were conducted with 21 Latinx SGM individuals from the Washington, DC, area. Data were analyzed using rapid qualitative analysis (RQA), and salient themes were identified. RESULTS: The RQA revealed 3 themes reflecting participants' experiences with pharmaceutical care during COVID-19 stay-at-home orders: (1) challenges in accessing HIV services; (2) community engagement; and (3) providers supporting access to care. Participants experienced problems with adherence to medication, transportation, and technology, as well as delays in care and miscommunication with providers. Latinx SGM individuals demonstrated engagement in response to this emergency as a community and valued their providers and their efforts to facilitate access to care. CONCLUSION: The COVID-19 pandemic strained healthcare services. Findings from this study show that the impact of the pandemic on the provision of care increased the vulnerability of Latinx SGM people. Future research should explore the impact of public health emergencies on the health of populations historically made socially vulnerable, and innovative solutions should be identified to eliminate these barriers to health equity.

Validez basada en la estructura interna, validez convergente y confiabilidad del Inventario de Dependencia Emocional (IDE) en adultos jóvenes / Validity based on internal structure, convergent validity and reliability of the Emotional Dependency Inventory (IDE) in young adults

La dependencia emocional es un constructo que está generando mayor interés por una parte de la comunidad científica. Por ello, es importante disponer de instrumentos que reúnan propiedades psicométricas adecuadas para su medición. El objetivo del estudio fue analizar las evidencias de validez basado en la estructura interna, validez convergente y medida de confiabilidad del Inventario de Dependencia Emocional (IDE). Participaron 1,401 adultos jóvenes (M =21 años, DE = 2.7; 24.2% varones y 75.8% mujeres), residentes en la ciudad de Lima, Perú. Se usó análisis factorial confirmatorio y medidas de asociación bivariada. Los resultados sugieren que el IDE presenta evidencias de validez de estructura interna para un modelo de siete factores oblicuos; dispone de evidencias de validez basado en la relación con violencia de pareja y satisfacción con la vida; y las dimensiones que la conforman presentan medidas de confiabilidad satisfactorias. Estos hallazgos pueden respaldar el uso del IDE en evaluación e investigación. (AU)

Emotional dependence is a construct that is generating greater interest by a part of the scientific community. For this reason, it is important to have instruments that have adequate psychometric properties for their measurement. The objective of the study was to analyze the evidence of validity based on the internal structure, convergent validity and reliability measure of the Emotional Dependency Inventory (IDE). A total of 1,401 young adults (M = 21 years old, SD = 2.7; 24.2% male and 75.8% female), residing in the city of Lima, Peru, participated. Confirmatory factor analysis and bivariate association measures were used. The results suggest that the IDE presents evidence of internal structure validity for a model of seven oblique factors; it has evidence of validity based on the relationship with intimate partner violence and satisfaction with life; and the dimensions that comprise it present satisfactory reliability measures. These findings may support the use of the IDE in evaluation and research. (AU)

Luces y sombras en la implementación de la acción comunitaria para la salud / Lights and shadows in the implementation of community action for health

Objetivo Explorar las experiencias de personas que desarrollan proyectos e intervenciones en los que la participación-acción comunitaria constituye una herramienta estratégica para reducir las desigualdades en salud. Método Estudio cualitativo basado en entrevistas en profundidad semiestructuradas realizadas en línea a personas consideradas expertas en el desarrollo de estrategias de promoción de la salud con participación comunitaria. Se seleccionaron 12 personas de los ámbitos sanitario, sociosanitario, académico y asociativo. Los textos se analizaron siguiendo el enfoque de análisis temático del contenido. Resultados La fortaleza destacada de los procesos en los que están involucradas las personas entrevistadas es su enfoque participativo. Sin embargo, no existe una apuesta real por promover la participación comunitaria desde la atención primaria de salud, y la precariedad ha sido señalada como la gran debilidad en el desarrollo de proyectos de promoción de la salud participativos. La sostenibilidad de los procesos participativos se basa en la transferencia de conocimiento hacia la comunidad y en su empoderamiento. Conclusiones Los procesos participativos han demostrado su capacidad para resituar a la comunidad como parte esencial que es del sistema sanitario. Sería interesante utilizar una herramienta de medición de la participación en toda acción comunitaria para la salud, tanto para orientar su diseño y planificación como para evaluar la profundidad de la participación y su impacto en el proceso. Mejorar las expectativas de la acción comunitaria para la salud en un futuro próximo pasa por potenciar una orientación comunitaria de la atención primaria y la intersectorialidad, lo que implica una gran apuesta institucional y política.

Comamonas testosteroni as the cause of mortality in embryonated chicken eggs of breeding broiler hens in Costa Rica.

Mortality of chicken embryos and first-week chickens was reported in a commercial incubator company in Costa Rica. Six 1-day-old Cobb chickens and twenty-four embryonated chicken eggs were examined in the Laboratory of Avian Pathology and the Laboratory of Bacteriology of the National University of Costa Rica. Twelve dead-in-shell embryos showed maceration and were immersed in a putrid, turbid, slightly thick brown liquid. Additionally, the other 12 embryonated eggs had milky yellow-orange content. The livers of those embryos had congestion, haemorrhages and multifocal cream foci of necrosis. Granulocytic infiltration was observed in the bursa of Fabricius, myocardium, liver, lung and kidney. Livers and egg yolks from six embryonated chickens and all 1-day-old chickens were aseptically collected and cultured. In addition, tissues from six better conserved embryos and all 1-day-old chickens were fixed in buffered formalin and embedded in paraffin. Biochemical and molecular tests identified Comamonas testosteroni as the cause of the early, middle and late embryo mortality. As all the eggshells from the sampled embryonated eggs were dirty with soiled a fecal matter, contamination after manipulating the eggs was considered the source of infection. C. testosteroni is an environmental microorganism that has rarely been reported to cause human disease. To our knowledge, this is the first report of C. testosteroni causing mortality in a hatchery. Cleaning and disinfection using ozone were implemented in the hatchery to eliminate the embryo mortality associated with C. testosteroni.

Short-, mid-, and long-term complications after multisystem inflammatory syndrome in children over a 24-month follow-up period in a hospital in Lima-Peru, 2020-2022.

Objective: To determine the short-, mid-, and long-term complications after multisystem inflammatory syndrome in children (MIS-C) over a 24-month follow-up period in a hospital in Lima, Peru, 2020-2022, and to explore differences according to the immunomodulatory treatment received and type of SARS-CoV-2 virus circulating. Methods: Ambispective 24-month follow-up study in children <14 years of age diagnosed with MIS-C at the Hospital Nacional Edgardo Rebagliati Martins (HNERM). Results: A total of 62 children were admitted with MIS-C. The most common short-term complications and serious events were intensive care unit (ICU) admission, invasive mechanical ventilation (IMV) due to respiratory failure, and shock; predominantly during the second pandemic wave (lambda predominance) and in children that received intravenous immunoglobulin (IVIG) plus a corticosteroid. Two patients died during the first wave due to MIS-C. During prospective follow-up (median of 24 months; IQR: 16.7-24), only 46.7% of patients were followed for >18-24 months. Of the total, seven (11.3%) patients were identified with some sequelae on discharge. Among the 43 remaining children, sequelae persisted in five (11.6%) cases (neurological, hematological, and skin problems). Six patients (13.9%) presented with new onset disease (hematologic, respiratory, neurological, and psychiatric disorders). One patient died due to acute leukemia during the follow-up period. None of them were admitted to the ICU or presented with MIS-C reactivation. Two patients presented persistence of coronary aneurysm until 8- and 24-month post-discharge. Conclusion: In our hospital, children with MIS-C frequently developed short-term complications and serious events during the acute phase, with less frequent complications in the mid- and long-term. More studies are required to confirm these findings.

Iron oxide-coupled CRISPR-nCas9-based genome editing assessment in mucopolysaccharidosis IVA mice.

Mucopolysaccharidosis (MPS) IVA is a lysosomal storage disorder caused by mutations in the GALNS gene that leads to the lysosomal accumulation of keratan sulfate (KS) and chondroitin 6-sulfate, causing skeletal dysplasia and cardiopulmonary complications. Current enzyme replacement therapy does not impact the bone manifestation of the disease, supporting that new therapeutic alternatives are required. We previously demonstrated the suitability of the CRISPR-nCas9 system to rescue the phenotype of human MPS IVA fibroblasts using iron oxide nanoparticles (IONPs) as non-viral vectors. Here, we have extended this strategy to an MPS IVA mouse model by inserting the human GALNS cDNA into the ROSA26 locus. The results showed increased GALNS activity, mono-KS reduction, partial recovery of the bone pathology, and non-IONPs-related toxicity or antibody-mediated immune response activation. This study provides, for the first time, in vivo evidence of the potential of a CRISPR-nCas9-based gene therapy strategy for treating MPS IVA using non-viral vectors as carriers.
