Effect of Emotional Word Processing on Communicative and Social Functioning in the Elderly / Efecto del procesamiento emocional de palabras en el funcionamiento comunicativo y social en el adulto mayor / Efeito do processamento emocional de palavras no funcionamento comunicativo e social em idosos

Communicative and social functioning in old age involves cognitive and emotional resources. According to the Socioemotional Selectivity Theory (tss), older adults have an affinity for positive events and cultivate their emotional skills. Objective: To explore the relationship between communicative and social functioning and the processing of emotional stimuli in the elderly. Materials and methods: Older adults and young adults performed a computerized lexical decision task (ldt) and were assessed on their com-municative functioning. Results: There were statistically significant differences in the valence factor, with faster processing of stimuli with emotional versus non-emotional content (2196 = 36.39, p <.001); Regarding communicative and social functioning, when comparing it with performance in the tdl, it was shown that older adults obtained longer reaction times and higher error rates in the processing of stimuli, as well as lower scores in the asha-facs. Conclusion: Even when there is no evidence of an interaction between the processing of emotional stimuli and communicative and social functioning, emotional valence influences word processing in older adults, with a preference and selectivity for positive stimuli.

Aim: To adapt and validate an existing instrument to assess the barriers to antiretroviral treatment adherence among individuals with hiv in Córdoba, Argentina. Materials and methods: The final sample population included 180 Argentinian people. The mean age of the participants was 40.61 (sd = 12.032) years and 82.8% were men. Various internal structure and reliability and validity studies with other variables were conducted on the study population (n = 180). Results: The results of confirmatory factor analysis were consistent with the factorial structure of the original study. However, to achieve this, items that had low factorial loads and were redundant had to be eliminated. Coefficient ω values of .833 on the Information sub-scale, .759 on the Motivation subscale, and .888 on the Behavioral Skills subscale were obtained. Significant correlations were determined between the results of adherence and barriers to treatment. Conclusion: The results suggest that the instrument can be used to assess the barriers to antiretroviral treatment adherence in Córdoba, Argentina. Although further research is warranted, these results are promising.

Psychosocial Risks and Mental Disorders among Mexican Oil Workers / Riesgos psicosociales y trastornos mentales en trabajadores petroleros mexicanos / Riscos psicossociais e transtornos mentais em trabalhadores petrolíferos mexicanos

The psychosocial risks faced by workers can influence their health as well as job performance and satisfaction. However, this phenomenon among Mexican workers in the oil industry has not been well studied. The purpose of this study was to analyze the association of stress and job-related burnout with mental disorders among oil workers in the southeastern region of Mexico. Materials and methods: This cross-sectional and analytical study included 501 workers from the onshore oil industry in the southeastern region of Mexico. The Work Burnout Inventory, the Symptoms of Stress Inventory, and the Goldberg General Health Questionnaire (ghq 28) were applied between October and November, 2016. Chi-square test was used to analyze the relationship between variables and the odds ratio was determined to establish the level of risk for mental disorders. Results: Moderate levels of stress (21.4l %), efficacy (41.5 %), cynicism (30.6 %), and exhaustion (39.7 %) were observed. Mental disorders were noted in 11.8 % of workers. Stress and burnout were associated with mental disorders (p < 0.05). Finally, workers who experienced stress and job burnout were more likely to have mental disorders (or = 12.96; 95 % ci [7.03­23.94]; p = 0.00). Conclusions:Stress and job burnout are risk factors for mental disorders among Mexican oil workers.

Análisis de la calidad de vida relacionada con salud oral en adultos con maloclusión / Analysis of the Oral Health-Related Quality of Life in Adults with Malocclusion / Análise da qualidade de vida relacionada à saúde bucal em adultos com má oclusão

aquellos pacientes que requirieron tratamiento de ortodoncia informaron impactos negativos en su calidad de vida relacionada con salud oral, en comparación con aquellos pacientes conclusión normal. El objetivo fue analizar la calidad de vida relacionada con la salud oral en pacientes con diferentes niveles de severidad de maloclusión que acudieron a consultorios odontológicos públicos de Paraguay durante el 2017. Materiales y métodos: estudio transversal. Se midieron variables sociodemográficas (como sexo, edad, residencia y nivel de estudios) y variables clínicas (como diastema, máxima irregularidad anterior maxilar y mandibular, resalte incisal y mordida cruzada anterior). Se utilizó el cuestionario Perfil de Impacto de Salud Oral en su versión paraguaya (ohip-14Py) y el Índice de Estética Dental (IED). Resultados: formaron parte del estudio 269 pacientes, la mayoría mujeres (75.1 %). El puntaje IED fue de 31.6 ± 11.6. Se observó resalte incisal aumentado (>2 mm) en poco más de la mitad (52.4 %) y una baja frecuencia de mordida cruzada anterior (5.9 %) y mordida abierta (10.0 %). Al evaluar por dimensiones, la incapacidad psicológica (p = 0.028), social (p = 0.034) y la minusvalía (p = 0.552) aumentaron conforme el nivel de severidad de maloclusión, por lo que fueron estadísticamente significativas las dos primeras. Conclusión: conforme aumenta la gravedad de la maloclusión, disminuye significativamente la calidad de vida oral para las dimensiones incapacidad psicológica e incapacidad social.

Patients requiring orthodontic treatment reported negative impacts on oral health-related qual-ity of life compared to patients with normal occlusion. Objective: To analyze the oral health-related quality of life in patients with different levels of severity of malocclusion attending public dental offices in Paraguay in 2017. Methodology: This was a cross-sectional study. Both, the sociodemographic variables, like sex, age, res-idence, and educational level, and the clinical variables, like diastema, maximum anterior maxillary, and mandibular irregularity, incisal overhang, and anterior crossbite were measured. The Oral Health Impact Profile questionnaire was used in its Paraguayan version (ohip-14Py) and the Dental Aesthetic Index (ied) scale. Results: A total of 269 patients were a part of the study. Moreover, 75.1 % of them were women. The ied score was 31.4 ± 11.6. An increase in the incisal protrusion (>2 mm) was seen in 52.4 % of the patients. Whereas a low frequency of anterior crossbite and open bite were seen in 5.9 % and 10.0 % of the population, respec-tively. While conducting an evaluation based on the dimensions, the psychological disability (p = 0.028), social disability (p = 0.034), and handicap (p = 0.552) increased according to the level of severity of malocclusion, being statistically significant in the first two. Conclusion: As the severity of the level of malocclusion increases, the oral quality of life decreases for the psychological disability and social disability dimensions.

Conclusão: à medida que a gravidade da má oclusão aumenta, a qualidade de vida oral diminui significativamente para as dimensões de incapacidade psicológica e incapacidade social.

Actividad antimicrobiana de extractos de plantas frente a Staphylococcus aislados de pacientes con conjuntivitis bacteriana / Antimicrobial Activity of Plant Extracts against Isolated Staphylococcus Infection in Patients with Bacterial Conjunctivitis / Atividade antimicrobiana de extratos vegetais contra Staphylococcus isolados de pacientes com conjuntivite bacteriana

Staphylococcus aureus y Staphylococcus epidermidis son los principales agentes etiológicos de las conjuntivitis bacterianas, que al tratarse con antibióticos de manera empírica, incrementan la resistencia antimicrobiana después de exposiciones repetidas. Se están buscando alternativas naturales para el tratamiento de infecciones bacterianas autolimitadas de la conjuntiva. Objetivo: determinar la actividad antimicrobiana de ocho extractos de las plantas frente a bacterias aisladas de pacientes con conjuntivitis bacterianas. Materiales y métodos: se tomaron muestras de 15 pacientes con conjuntivitis bacterianas. Se cultivaron en agar sangre y chocolate durante 24 h a 37 °C y se identificaron mediante el sistema automatizado vitek y pruebas de susceptibilidad antimicrobiana por el método de Kirby-Bauer. A cada aislamiento identificado con el género Staphylococcus se le evaluó su susceptibilidad frente a siete extractos: Ocimum basilicum, Sambucus nigra L., Delphinium elatum, Calendula officinalis, Bixa ore-llana (parte aérea y fruto independiente), Clinopodium brownei y Laurus nobilis, con un uso tradicional reportado para el tratamiento de infecciones oculares. Resultados: las bacterias aisladas con más frecuencia fueron S. epidermidis, S. hominis y S. aureus, las cuales presentaron resistencia antimicrobiana a oxacilina, tetraciclinas y eritromicina. Todos los aislamientos fueron inhibidos por los extractos de O. basilicum (cmi: >0.9 mg/mL) y L. nobilis (cmi: hasta 15 mg/mL). Conclusión: los extractos de C. officinalis y D. elatum tuvieron actividad antimicrobiana solo frente a los aislados con mayor sensibilidad antimi-crobiana. Los extractos etanólicos de O. basilicum y L. nobilis pueden ser una alternativa de tratamiento de las infecciones de la conjuntiva.

Staphylococcus aureus and Staphylococcus epidermidis are the primary etiological agents of bacterial conjunctivitis which are empirically treated with antibiotics. This results in an increase in antimicrobial resistance due to repeated exposure. Currently, natural treatment alternatives are being sought for self-limited bacterial infections of the conjunctiva. Objective: To determine the antimicrobial activity of eight extracts from Colombian plants against bacteria isolated from patients with bacterial conjunctivitis. Materials and methods: Samples were taken from 15 patients with bacterial conjunctivitis which were grown on blood and chocolate agar for 24 h at 37 °C. These samples were identified by the vitek automated system and antimicrobial susceptibility tests by the Kirby Bauer method. Each isolate identified with the genus Staphylococcus was evaluated for susceptibility to the following eight plant extracts of seven plant: Ocimum basilicum (basil), Sambucus nigra L. (elderberry), Delphinium elatum(belladonna), Calendula officinalis (marigold), Bixa orellana (annatto) (aerial part and independent fruit), Clinopodium brownei (pennyroyal), and Laurus nobilis (laurel), with traditional use previously reported for treating eye infections. Results: The most frequently isolated bacteria were S. epidermidis, S. hominis, and S. aureus, which exhibited antimicrobial resistance mainly to oxacillin, tetracyclines, and erythromycin. All isolates were inhibited by O. basilicum extracts (mic > 0.9 mg/mL) and L. nobilis (mic < 15 mg/mL). Conclusion: The extracts of C. officinalis y D. elatum showed antimicrobial activity only against isolates with higher antimicrobial sensitivity. Ethanolic extracts of O. basilicum y L. nobilis can be used as an alternative treatment for infections of the anterior segment of the eye.

Compassion fatigue influences the mental health and turnover intention of nurses in the COVID-19 pandemic

Background@#Compassion fatigue is a true phenomenon experienced by overworked and exhausted nurses.@*Objective@#This study assessed frontline nurses' compassion fatigue, stress, mental health, and turnover intention during the second year of the COVID-19 outbreak.@*Methods@#Using a cross-sectional design, an online survey was administered in the first quarter of 2021 to 259 hospital nurses in the Central Philippines using standardized scales to gather the necessary data. @*Results@#Nurses were found to have moderate levels of compassion fatigue and turnover intention, high stress, and good mental health. Results revealed that compassion fatigue was associated with poor mental health (r = −5.05, p = 0.01), higher stress levels (r = 0.54, p = <0.001), and turnover intention (r = 0.27, p = <0.001). @*Conclusion@#Pandemic-related compassion fatigue in nurses increases their stress, worsens their mental health, and heightens their intentions to leave their jobs. Organizations should address compassion fatigue through a supportive work climate.

Perspectives on the use of telegenetics services in the Philippines

@#The Philippines is a densely populated nation faced with multiple challenges in the healthcare field given its geographic, cultural, and socioeconomic barriers. Due to the geographic limitations of medical services in the country, many patients must travel a great distance to referral centers. This was further exacerbated by the Coronavirus disease 2019 (COVID-19) pandemic, which spread across the world and upended lives. This pandemic triggered a public health crisis that impacted healthcare systems, healthcare workers, and communities worldwide. It compounded current difficulties with the provision and accessibility of medical services, necessitating the employment of alternative methods of providing health coverage. As a result, advanced technological methods for patient diagnosis, monitoring, treatment, and counseling were rapidly implemented.1 Interest in these technological advances began prior to the COVID-19 pandemic, though primarily in developed countries. However, during this global outbreak, telehealth practices – which refer to online health care services provided by all health care professions – have seen a rapid increase in popularity.2,3 Telehealth was brought to the forefront in all countries in order to surmount lockdown constraints, allow continuous provision of health care for patients, and limit exposure to health systems and health providers.4 Traditional medical education and training were likewise disrupted during this time, resulting in the incorporation of telehealth into medical education. To reduce the risks associated with more personnel in the hospital, medical students were withdrawn from clinical environments during the COVID-19 outbreak. This created an environment of uncertainty and limited clinical exposure, with concerns surrounding progression through the medical course and training program.5 Continuing medical education, which has traditionally been based on clinical knowledge and skills, now requires online technical communication skills. Innovative services were rapidly developed with health professionals embracing this new technological competence, enabling general consultation for patients, remote patient monitoring, and self-directed patient care, thereby decreasing the burden on health facilities. Digital learning platforms also provided an effective way to address the learning gaps caused by the pandemic. The restriction of “in-person” delivery of healthcare services due to the global outbreak has prompted physicians, including clinical geneticists and genetic counselors, to investigate alternative methods of providing health care to patients. A telehealth innovation for online delivery of clinical genetic and genetic counseling services is the Philippine General Hospital’s Telegenetics Service. Despite being launched in 2013 to serve genetics patients across the country, this service has since been upgraded and capitalized resulting in patient appreciation for its COVID-19 exposure prevention, increased access, and time and cost efficiency. However, the telegenetics service has its limitations.6,7 Despite the expanding scope of telehealth/telegenetics and its immediate application, issues such as data/patient privacy, organizational readiness, digital maturity, regulatory impediments, access and acceptance of the technology, geographical and digital disparities, and its integration with traditional medical services have emerged.8 Lack of a detailed physical examination is also lost in a virtual visit, with focused questions leading to fragmented, impersonal interactions. Even when restrictions were lifted, telehealth usage nonetheless remained significantly higher than it had been prior to the pandemic. This may indicate a shift in public opinion in favor of this innovative medical practice.9 With the expansion of genetic services in the country, there is now a greater need for telegenetics due to the increased demand for clinical genetic and genetic counseling expertise. Therefore, evidence on the safety and efficacy of this technology in comparison to the traditional healthcare delivery approach is required. If the technology has the potential to improve health care, we must guarantee its availability in all resource-limited areas. Future efforts should thus focus on establishing solutions to address the aforementioned issues and concerns within our healthcare and education systems, thereby ultimately enhancing the standard of medical care.

Supporting undergraduate research capacity development: A process evaluation of an Undergraduate Research Office at a South African Faculty of Medicine and Health Sciences

Background. University-based research capacity development (RCD) mechanisms tend to focus on staff and postgraduate students, with few structures targeted at undergraduate students. Support for undergraduate research must be tailored to the unique requirements of research at this level, while maintaining links with relevant structures in both the RCD and teaching and learning domains. Objective. To conduct a process evaluation of the Undergraduate Research Office (URO) in the Faculty of Medicine and Health Sciences at Stellenbosch University, South Africa, using RCD and characteristics of excellence in undergraduate research criteria as benchmarks. Methods. A process evaluation of URO's first 6 years was conducted using a logic model of URO's inputs, activities, and outputs. Through a retrospective document review, a descriptive analysis of URO's inputs and activities (narrative) and URO's outputs (statistical) was conducted. Results. Following a description of inputs and activities, results present URO's outputs as a measure of the uptake of these activities. From 2015 to 2020, 259 undergraduate research projects were completed. Research consultations, workshops and undergraduate presentations at the faculty's Annual Academic Day have more than doubled since URO's inception. The Undergraduate Research Ethics Committee has reviewed 243 ethics applications since 2015, with a 1 - 2-week turnaround time. A total of 134 funding applications worth ZAR705 986 have been awarded for research project, conference presentation and publication costs. Conclusion. Results show the potential impact of a formal undergraduate research support entity on the undergraduate research outputs of a Faculty of Medicine and Health Sciences. This article highlights elements for success for formal undergraduate research support, and identifies gaps going forward.

The use of peer physical examination in undergraduate health professions education: Exploring the perceptions of students and educators in a multicultural, multiracial institution

To investigate the lived experience and perceptions of students and educators on the use of PPE in undergraduate health professions education at a multicultural and multiracial institution. Suggestions on guidelines for a PPE policy for the FoHS at the UFS were also obtained from the participants.Methods. This research was designed as a qualitative study that used focus group interviews involving 26 participants (19 students and 7 educators) to obtain verbal statements that described their experience and perceptions of the use of PPE in undergraduate health professions education. Results. Participants reported that PPE was useful to create a safe learning environment and to prepare students for the clinical aspects of their training. Enhancing students' empathy, competency and clinical confidence were among the advantages attributed to using PPE; it also encouraged peer-assisted learning. Some of the disadvantages ascribed to PPE were that it made it difficult to maintain classroom discipline, and that it could promote memorisation over understanding. Finally, participants suggested that a guideline for PPE policy should address matters of consent, confidentiality, participation and gender, cultural, religious and racial considerations.Conclusions. The findings of this study reveal that PPE is an acceptable and useful learning strategy for the majority of students and educators. Issues relating to consent, confidentiality and cultural, religious and racial considerations are some of the potential problems associated with the use of PPE at the UFS. We believe that the suggestions given by the participants of this study will inform the establishment of a PPE policy for the FoHS of the UFS

Perceptions of undergraduate allied health students of the clinical learning environment and clinical educators' attributes at the University of Ghana

Background. Clinical education is a vital aspect of the education of health sciences students and consists of two components, i.e. the clinical learning environment and supervision.Objectives. To determine the undergraduate allied health sciences students' perceptions regarding clinical educators' attributes and the clinical learning environment.Methods. This cross-sectional study included 169 undergraduate students, randomly recruited from various allied health professions programmes of the University of Ghana. The McGill clinical teacher evaluation tool and the clinical learning environment inventory were used to determine students' perceptions of clinical educators' attributes and the clinical learning environment, respectively. The Kruskal-Wallis test and independent t-tests were used to test for relationships between students' level and programme of study and their perceptions. The level of significance was set at 95%.Results. Of the 169 participants, there were 99 (58.6%) male students, 79 (46.7%) third-year students and 82 (48.5%) medical laboratory science students. Only 16 (9.5%) participants indicated visits by lecturers during clinical rotations. The third-year students had a statistically significant perception of their clinical learning environment (p=0.000), while the differences between perceptions of clinical learning environment among the various programmes were also statistically significant (p=0.028), but not for clinical educators' attributes (p=0.261).Conclusion. Allied health sciences students have positive perceptions of their clinical learning environment and clinical educators' attributes. More frequent visits by lecturers to students during clinical rotations may ensure that student innovation is achieved in accordance with their classroom tuition

Men in the service of humanity: Sociocultural perceptions of the nursing profession in South Africa

Background. The classification of nursing as a female-gendered profession, along with patriarchally determined cultural gender roles, makes it difficult for men to select nursing as a career and to excel in their caring capacity as nurses.Objective. To gain in-depth insights into and an understanding of male nursing students' perceptions of the nursing profession. Methods. A generic qualitative approach, which was explorative, descriptive and contextual, was used to conduct the study. Sixteen male nursing students at two nursing education institutions in KwaZulu-Natal Province, South Africa, were purposively sampled to participate in the study. Data were collected using semi-structured interviews and unstructured observation. Thereafter, thematic analysis was used to analyse the data. Results. Three main themes were developed from the interview data. The participants perceived nursing as the extension of women's work, with low social status ‒ nursing is not considered to be a profession for men. During the provision of nursing care, feelings of discomfort and embarrassment were experienced. They feared misinterpretation of their care, especially when caring for the naked body when alone with a patient. They resorted to the use of cautious caring, where they do not provide physical care alone, but seek support, especially from female nurses.Conclusion. Male nursing students require role models to support them in their academic journey towards becoming competent practitioners. A male-friendly environment should be created to enable them to provide quality nursing care to all patients. The society needs to be empowered in understanding that men choose the nursing profession to provide care, and that they are capable of caring for the sick.

High-fidelity simulation: A practice model for nurse educators at a South African private higher education institution

Background. The clinical skills development of student nurses is one of many challenges facing nursing education owing to a lack of available clinical placements and learning opportunities. Simulation training as an optional teaching-learning method creates an environment where clinical skills are developed and students are prepared for the nursing profession. The successful implementation of high-fidelity simulation (HFS) strategies as part of the nursing curricula requires nurse educators to have knowledge and skills. At the South African private higher education institution (SAPHEI) where the research for this study was done, it became evident that nurse educators do not have the required knowledge, skills or support to implement HFS. The absence of evidence in the literature of a practice model for a SAPHEI to facilitate the implementation of HFS reveals a gap in the practice base of nursing education.Objective. To develop a practice model for nurse educators at a SAPHEI to facilitate the implementation of HFS.Methods. The researcher used a theory-generative research design. The study was conducted in two phases, with two steps in each phase, to address four objectives in all.Results. Phase 1 identified and described the main and related concepts. A resulting conceptual framework was used for the development of the practice model. Phase 2 addressed the relational meaning of the main and related concepts, as well as the construction of the practice model through theory synthesis.Conclusion. The main aim of this research study was to develop a practice model for nurse educators at a SAPHEI to facilitate the implementation of HFS as part of the clinical skills development of student nurses. The practice model offers a schematic outline that represents HFS as a teaching-learning method. The importance of the outline lies therein that it specifies the context and situations in which the model is useful

Schistosomiasis and soil-transmitted helminthiasis morbidity control in selected communities in Eastern Visayas, Philippines: Post-Haiyan

Objective@#As part of the evaluation of control programs recommended by WHO, this study describes the local implementation of schistosomiasis (SCH) and soil-transmitted helminthiasis (STH) morbidity control as well as water, sanitation, and hygiene (WASH) interventions post calamity. It likewise determines the challenges, areas for improvement, and good practices in SCH and STH morbidity control strategies in Haiyan-stricken areas in Eastern and Western Samar, the Philippines. @*Methods@#Twenty key informant interviews and eight focus group discussions documented the implementation of SCH and STH control strategies in Eastern Visayas. Data analysis was done manually by a multi-disciplinary team. @*Results@#Mass drug administration (MDA) in schools and communities was conducted for morbidity control. MDA for STH for pre-school-age children was integrated into the Garantisadong Pambata program, while a schoolbased teacher-assisted approach was used for school-age children. WASH facilities, such as sanitary toilets, were constructed through the initiatives of the local government units (LGUs) and other private sectors. Partnerships with Plan International Philippines helped in the implementation of WASH through the conduct of Community-led Total Sanitation. Health advocacies helped instill behavioral change in the community. SCH surveillance was conducted annually while STH surveillance was irregularly implemented. Data on MDA coverage were validated through Rapid Coverage Assessment before final reporting. Discrepancies were observed due to typographical errors and the inclusion of teachers and transient migrants in the reports submitted. Challenges in the implementation of MDA include delays in drug delivery, lack of human resources, non-compliance of participants, and drug unpalatability. Challenges in WASH included the lack of hand washing facilities, inaccessibility to safe water, as well as non-utility of sanitary toilets. Strengthening health advocacy and education may help address these challenges.@*Conclusion@#The involvement and partnership of various stakeholders such as LGUs, WASH, and veterinary sectors, together with the academe are needed to strengthen and enhance the implementation of SCH and STH control activities. An integrated approach may contribute to improvements in SCH and STH prevention and control of the communities in selected Haiyanstricken areas.

Identification of potential prognosticators for sepsis through expression analysis of transcriptomic data from sepsis survivors and nonsurvivors

Background@#Infection can be severely complicated by a dysregulated, whole-body inflammatory response known as sepsis. While previous research showed that genetic predisposition is linked to outcome differences, current patient characterization fails to determine which septic patients have greater tendencies to develop into severe sepsis or go into septic shock. As such, the identification of prognostic biomarkers may assist in identifying these high-risk patients and help improve the clinical management of the disease.@*Objective@#In this study, we aimed to identify molecular patterns involved in sepsis. We also aimed to identify essential genes associated with the disease’s survival which could serve as potential prognosticators for the disease. @*Methods@#We used weighted gene co-expression analysis (WGCNA) to analyze GSE63042, an RNA expression dataset from 129 patients with systemic inflammatory response syndrome or sepsis, including 78 sepsis survivors and 28 sepsis nonsurvivors. This analysis included identifying gene modules that differentiate sepsis survivors from nonsurvivors and qualitatively assessing differentially expressed genes. We then used STRING’s protein-protein interaction and gene ontology analysis to determine the functional and pathway relationships of the genes in the top modules. Lastly, we assessed the prognosticator abilities of the hub genes using ROC analysis. @*Results@#We found four diverse co-expression gene modules significantly associated with sepsis survival. Our differential gene expression analysis, combined with protein-protein interaction and gene ontology analysis, revealed that the hub genes of these modules – TAF10, SNAPIN, PSME2, PSMB9, JUNB, and CEBPD – may serve as candidate markers for sepsis prognosis. These markers were significantly downregulated in sepsis nonsurvivors compared with sepsis survivors.@*Conclusion@#Weighted gene co-expression analysis, gene ontology enrichment analysis, and proteinprotein network interaction analysis of transcriptomic data from sepsis survivors and nonsurvivors revealed TAF10, SNAPIN, PSME2, PSMB9, JUNB, and CEBPD as potential biomarkers for sepsis prognosis. These genes are associated with functions related to proper immune response, and their downregulation in sepsis nonsurvivors suggests eventual immune exhaustion in late sepsis. Further analyses, however, are necessary to validate their roles in sepsis progression and patient survival.

Necrosis uterina tras sutura de compresión hemostática: reporte de caso y revisión de la literatura / Uterine necrosis following hemostatic compression suture: case report and review of the literature

Objetivos: presentar un caso de necrosis uterina tras técnica de sutura hemostática por hemorragia posparto y hacer una revisión de la literatura para determinar la técnica de sutura utilizada, los hallazgos clínicos, la técnica diagnóstica y el tratamiento realizado en los casos clínicos descritos. Materiales y métodos: se presenta el caso de una mujer de 34 años que consultó por dolor abdominal al octavo día tras cesárea por placenta previa, que precisó sutura de B-Lynch por atonía uterina y cuyo diagnóstico fue necrosis uterina. La paciente requirió histerectomía abdominal total, con evolución satisfactoria. Se realizó una búsqueda sistemática de la literatura en las bases de datos Medline vía Pubmed, Embase y Web of Science. Se buscaron series y reportes de casos y cohortes de mujeres con necrosis uterina posterior al uso de suturas de compresión uterina para control de hemorragia posparto. Se analizaron variables sociodemográficas y clínicas al diagnóstico, técnica de sutura, pruebas diagnósticas y tratamiento. Resultados: se incluyeron 23 estudios con 24 pacientes. El 83 % de las necrosis ocurrieron tras cesárea. La técnica más utilizada fue B-Lynch (66 %), seguida de Cho (25 %). Los síntomas más frecuentes fueron fiebre y dolor abdominal. La prueba diagnóstica más utilizada fue la tomografía computarizada (9 de 24 casos). En la mayoría de casos se realizó histerectomía (75 %). Conclusiones: la necrosis de la pared uterina es una complicación infrecuente pero grave. Sería recomendable el diseño de cohortes de seguimiento de mujeres sometidas a estos procedimientos para determinar la incidencia de complicaciones asociadas.

Objectives: To present a case of uterine necrosis following hemostatic suturing to control postpartum bleeding, and to review the literature in order to identify the suture techniques employed, clinical findings, diagnostics and treatment in the clinical cases described. Materials and Methods: A 34-year-old woman presenting with abdominal pain eight days after cesarean delivery due to placenta previa who required B-Lynch compression suture due to uterine atony, and who was diagnosed with uterine necrosis. The patient underwent total abdominal hysterectomy with a satisfactory recovery. A systematic literature search was conducted in the Medline vía Pubmed, Embase and Web of Science databases. The search included case series and reports, and cohorts of women with uterine necrosis following the use of uterine compression sutures for postpartum bleeding. The analysis included sociodemographic and clinical variables at the time of diagnosis, suturing technique, diagnostic tests and treatment. Results: Overall, 23 studies with 24 patients were included. Of all necrosis cases, 83% occurred following cesarean section. B-Lynch was the suturing technique most frequently used (66 %), followed by the Cho suture (25 %). The most frequent symptoms were fever and abdominal pain. The most commonly used diagnostic test was computed tomography (9/24 cases). Hysterectomy was performed in the majority of cases (75 %). Conclusions: Although rare, uterine wall necrosis is a serious complication. It would be advisable to design follow-up cohort studies of women undergoing these procedures in order to determine the incidence of associated complications.

Las prácticas de integración cuerpo-mente como promotoras de estados emocionales saludables / Mind­Body Integration Practices as Promoters of Healthy Emotional States / Práticas de integração corpo-mente como promotoras de estados emocionais saudáveis

Recientes investigaciones provenientes de diversos campos emergentes como la psiconeu-roinmunología, la medicina integrativa o la pigenética han dado cuenta de la estrecha vinculación entre los estados emocionales y la salud. El objetivo fue evaluar la eficacia de una intervención basada en la realización de prácticas de integración cuerpo-mente sobre la regulación emocional. Materiales y métodos: en 102 participantes, de entre 34 y 65 años de edad, se analizaron cambios en la Escala de Afectividad Positiva y Negativa (panas), antes y después de participar en la intervención propuesta, que se realizó durante ocho encuentros de seis horas de duración cada uno, a lo largo de cuatro meses. Resultados: se encontró un aumento en la afectividad positiva y una disminución en la afectividad negativa luego de la intervención. El índice de afectividad (i. e. afectividad positiva/afectividad negativa) se incrementó de una relación 2:1 a una relación 3:1. Esta última proporción ha sido asociada con estados saludables. Conclusiones: el estudio contribuye a demostrar el beneficio que brindan las prácticas de integración cuerpo-mente en la regulación emocional y la afectividad positiva. Esto podría propiciar un mayor bienestar psicofísico individual y colectivo.

Recent research from various emerging fields, such as psychoneuroimmunology, integra-tive medicine, and epigenetics, showed a close link between emotional states and health. This study was designed to evaluate the effectiveness of an intervention based on mind­body integration practices in emotional regulation. Materials and Methods: We evaluated changes in the positive and negative affectivity scale in 102 participants before and after the intervention, which was performed during eight meetings lasting 6 h each, for 4 months. Results: An increase in positive affectivity and a decrease in negative affectivity were found after the intervention. The affectivity index (i.e., positive affectivity/negative affectivity) increased from a 2:1 ratio to a 3:1 ratio. This latter ratio has been associated with healthy states. Conclusions: This study demonstrated that mind­body integration practices can confer to emotional regulation and positive affectivity. These beneficial effects could improve psychophysical well-being at both the individual and collective levels.

Noncommunicable diseases are a public health issue that burdens health systems, econo-mies, and society. These diseases can be prevented by using several methods, such as the social appro-priation of knowledge, empowerment of communities, and improvement of their health indicators. This review seeks to describe the methodologies used in designing strategies for the social appropriation of health knowledge in the prevention of noncommunicable diseases in adults worldwide. Materials and methods: A systematic review of articles containing social appropriation of health knowledge strategy was made searching the following databases Google Scholar, ovid, Virtual Health Library, Medline, ebsco, and SciELO. With the following criteria: publications in journals indexed between 2016 and 2021; writ-ten in English, Portuguese, and Spanish; and addressing health intervention topics. Results: A total of 39 articles were reviewed, of which 36 were qualitative, 2 mixed, and 1 cross-sectional. The methodological approach used to develop the strategies was community-based participatory research (cbpr). Based on the characteristics shared by the various phases of the studies, four common characteristics were identi-fied: community diagnosis, intervention design, implementation, and evaluation. Conclusions: cbpr is the most widely used method for the social appropriation of health knowledge for the adult population, par-ticularly in populations at high social, economic, and health risks. The research trend made it possible to recognize the significance of community diagnosis as a stepping stone to the design, implementation, and evaluation of jointly developed strategies.

Colágeno tipo I en el agrandamiento gingival inducido por tratamiento ortodóntico: un estudio inmunohistoquímico piloto / Type I Collagen in Gingival Overgrowth Induced by Orthodontic Treatment: A Pilot Immunohistochemical Study / Colágeno do tipo I no aumento gengival induzido por tratamento ortodôntico: um estudo imuno-histoquímico piloto

el tratamiento ortodóntico es responsable del agrandamiento gingival (ag), una condición clínica caracterizada por el crecimiento patológico, difuso o localizado del tejido gingival. La acumulación excesiva de la matriz extracelular (mec), incluyendo el colágeno tipo I, parece contribuir a las manifestaciones patológicas del ag. El objetivo del artículo es identificar y describir la distribución del colágeno tipo I en el tejido gingival de pacientes con ag por ortodoncia fija. Materiales y métodos: estudio de tipo descriptivo que analizó los tejidos gingivales de sujetos diagnosticados con ag portadores de ortodoncia (test, n = 5) e individuos periodontalmente sanos (control, n = 5). Las muestras se obtuvieron mediante gingivectomía. Todas las biopsias fueron fijadas, incluidas en parafina, cortadas y analizadas por medio de la coloración rojo picrosirius/verde rápido, con el propósito de distinguir las fibras de colágeno. Mediante una reacción inmunohistoquímica, el colágeno tipo I fue identificado con anticuerpo monoclonal. Resultados: en los pacientes con ag por tratamiento ortodóntico, se identificó un tejido epitelial hiperplásico con aumento evidente de las prolongaciones epiteliales y un tejido conectivo con abundantes haces de fibras de colágenos, principalmente en la lámina basal y la zona subyacente. Las fibras de colágeno tipo I en los tejidos de pacientes con ag por ortodoncia fueron gruesas de aspecto desorganizado, con una tinción inmunohistoquímica intensa, en comparación con las fibras del grupo control. Conclusiones: el aumento de fibras de colágenos, en especial de colágeno de tipo I, es un hallazgo histológico que caracteriza a los pacientes con ag por ortodoncia fija.

Orthodontic treatment is responsible for gingival overgrowth (go), a clinical condition charac-terized by pathological, diffuse, or localized growth of gingival tissue. Excessive accumulation of the extra-cellular matrix, including type I collagen, contributes to the pathological manifestations of go. The objective of this study is to identify and describe the distribution of type I collagen in the gingival tissue of patients with go because of fixed orthodontics. Materials and Methods: A descriptive study that analyzed the gingival tissues of subjects diagnosed with go with orthodontic (test, n = 5) and periodontally healthy individuals (control, n = 5). The samples were obtained by gingivectomy. All the biopsies were fixed, embedded in paraf-fin, and cut and analyzed using picrosirius red/fast green staining, in order to distinguish the collagen fiber. By means of an immunohistochemical reaction, type I collagen was identified with a monoclonal antibody. Results: A hyperplastic epithelial tissue was identified with an evident increase in epithelial processes and connective tissue with abundant bundles of collagen fiber, mainly in the basal lamina and the underlying area in patients with go because of orthodontic treatment. Type I collagen fiber in the tissues of patients with orthodontic go were thick and disorganized in appearance with intense immunohistochemical stain-ing, compared to the fibers of the control group. Conclusions:The increase in collagen fibers, particularly type I collagen, is a histological finding that characterizes patients with go because of fixed orthodontics.
