"It Becomes a Family I'm a Part of We Get to Carry Each Other": Themes from Qualitative Interview of Patients Enrolled in an Inpatient Palliative Care Support Program for Adolescents and Young Adults.

Background: The pediatric palliative care literature provides little evidence regarding the lived experiences of adolescents and young adults (AYAs). Objectives: We sought to evaluate the aspects of a palliative care peer support program, which were most helpful to patients, and identify areas for improvement to better address their psychosocial needs. Design: This was a retrospective, cross-sectional study, which described self-reported Streetlight program evaluation using thematic analysis of interviews with AYAs. A total of 10 interviews was completed. Setting/Subjects: Thirty-three current and former Streetlight participants (13-30), enrolled in the Streetlight program for at least six months, were recruited during hospital admissions and clinic visits at UF Health Shands Hospital in the United States. Of the 33, 2 participants died before interviews could be conducted. A total of 10 interviews were conducted. Results: Thematic analysis of the 10 individuals identified 5 themes. They were (1) normalization of life in hospital, (2) mental health and instillation of hope, (3) companionship and connection, (4) diversity of volunteers, and (5) gratitude. Conclusions: Results suggest that AYAs who participated in a peer support, palliative care program benefitted from their exposure to volunteer social support. Addressing the need for continued study of this population provides opportunities to expand peer support, pediatric palliative care programs to other hospitals and care facilities.

A Novel Palliative Care Peer Support Program for Adolescents and Young Adults: Survey and Factor Analytic Study.

Background: Palliative care literature indicates a dearth of programs addressing the psychosocial needs of adolescents and young adults (AYAs). Objectives: This study assessed patient-reported experiences of a palliative care peer support program, analyzed psychometric qualities of the program evaluation, and examined associations with quality-of-life scores to assess validity and potential impact on aspects of AYA quality of life. Design: This retrospective, cross-sectional study described self-reported Streetlight program evaluation and quality of life of AYA patients, exploratory factor analysis of survey responses, and analysis of associations with quality of life. Setting/Subjects: AYA participants (13-30) enrolled in the Streetlight program for at least six months were recruited during hospital admissions and clinic visits at UF Health Shands Hospital. Results: Participants' (n = 69) scores were high for Youth Quality of Life Instrument-Short Form (YQOL-SF) (82.6 of 100), and Streetlight evaluations (4.47 of 5). Patients endorsed themes of: high-quality friendships with volunteers, transformative impacts to wellbeing, and benefits to mental health and coping in open-ended responses. Analyses identified three factors explaining 61% of variance in Streetlight program evaluation responses: "Friendships and Support" (26%); "Coping, Family, and Providers" (20%); and "Diversion and Respect" (15%). Significant positive associations were found between Streetlight evaluation scores and YQOL-SF Belief in Self and Family factor scores, as well as between Streetlight evaluation Friendships and Support factor scores, and YQOL-SF total and factor-specific scores. Conclusions: Results suggest that the Streetlight program is a viable model to facilitate positive experiences, opportunities for socialization, and meaningful peer support for AYA patients.

Introduction: the influenza virus infection causes morbidity and mortality. Health care personnel (HCP) is one of the priority groups to be vaccinated. Objective: to learn about HCP's vaccination coverage against influenza of those workers working with children at CASMU in 2019 and 2020, and the reasons why they received vaccination or did not. Material and Methods: observational, descriptive, crosssectional study. Data collection in 2020: anon ymous survey. Variables: age, place of work (emer gency, hospital or clinic), function, risk of serious illness, vaccination received (or not received) in 2019 and 2020 and reasons. Results: 204 workers completed the survey; influenza vaccination: 73% in 2019 and 77.5% in 2020 (p>0.05). Montevideo's Emergency Department presented the highest level of vaccination and hospitalization (2019-90.7%; 2020-93%) followed by the Ciudad de la Costa's Emergency Department. By occupational level: doctors: vaccination> 95% (2019 and 2020); graduates and nursing assistants: 2019-68.6%; 2020- 75.7%; administrative, kitchen, cleaning and gate house staff: 2019-33%, 2020-41%. The increase in vaccinated personnel in 2020 was not significant for any of the occupations. 21% of those surveyed had a risk of serious illness; 65% were vaccinated in 2019 and 74.4% in 2020. All the sampled pregnant women were vaccinated. The most frequent reasons mentioned for vaccination (2019 and 2020): "prevention" (50.5%), being PS (36%). Those who were not vaccinated stated that were "never ill" (19%). Those who had not received the vaccine in 2019, but received in 2020, mostly mentioned the "pandemic" as a reason. Conclusion: in CASMU, the percentage of health workers in contact with children who adhered to the flu vaccination in 2019 and 2020 was higher than 70%. There was no significant increase after to the pandemic. Coverage in polyclinics and nonmedical HCP, in particular those HCP with risk factors for serious diseases, should be improved.

Practicing Mindfulness through mHealth Applications: Emerging Adults' Health-Enhancing and Inhibiting Experiences.

Mindfulness-based interventions (MBIs) and practices (MBPs) can promote better health outcomes. Although MBIs and MBPs were developed to be delivered in-person, mobile health (mHealth) tools such as apps have made these more accessible. Mindfulness apps (MAs) are popular among emerging adults (EAs) who have the highest ownership of smartphones and who are also at risk for distress. While adverse effects have been observed with MBIs/MBPs, this has not been examined when mindfulness is practiced using apps. We interviewed EAs (n = 22) to capture their motivations for using these apps and identified health-inhibiting and enhancing experiences. Data were thematically analyzed using the constant comparative method. Motivations for app use included accessibility, convenience, and stress/health management. EAs described health-enhancing outcomes (reduced distress, improved physical symptoms, increased focus) and health-inhibiting outcomes (worsened distress, performance uncertainty, dependency development, worsened physical health). They provided suggestions for improving apps (e.g., feedback option). These findings illustrate benefits and risks that EAs may encounter when practicing mindfulness using apps, which can inform the best practices for app design.

Volunteer-Based Social Support Structures and Program Exposure Outcomes in an Adolescent Young Adult Palliative Care Peer Support Program.

Objective: To conduct a social network analysis (SNA) of patient-volunteer networks and assess the impact of patient characteristics on network measures. Background: Volunteers play a critical role in providing peer support to adolescent and young adult (AYA) palliative care patients. Streetlight at UF Health is a peer support palliative care program for hospitalized AYAs that aims at forming positive peer relationships through volunteer visits, events, and a virtual online health community. Methods: Data were collected on patient characteristics, hospitalizations, average length of stays (LOS), and volunteer visitation records. Egocentric SNAs were conducted on each patient to calculate network outcomes. Study participants were AYA patients (N = 69), enrolled in the US-based Streetlight program at UF Health Shands Hospital. Results: The LOS was significantly associated with network size (B = 0.583; 95% confidence interval; CI [0.463 to 0.702]). Autoimmune patients had smaller network sizes when controlling for LOS. Total hospital admissions predicted - 0.172 ([- 0.263 to - 0.080]) lower average repeat visits. Higher average repeat visits were predicted for patients who had cancer (B = 0.246 [0.046 to 0.447]) and awaiting organ transplantation (B = 0.370 [0.082 to 0.658]). Although cystic fibrosis patients received more visits (B = 0.364 [0.003 to 0.724]) compared with other illness populations, the network density was lower (B = - 0.580 [1.01 to - 0.155]). Cancer patients had networks with a higher diversity in volunteer repeat visits (B = 0.714 [0.312 to 0.920]). Conclusions: Significant relationships between patient characteristics and network outcomes highlight the differences in social support service delivery among diverse populations. These analyses can be utilized in practice to guide program delivery for high-need patients.

La odontogeriatría en la formación y superación de especialistas en Cuba / Geriatric Dentistry in the training and improvement of specialists in Cuba

Introducción: El envejecimiento de la población mundial en el nuevo milenio propicia que la atención al paciente geriátrico se mantenga como tema trascendental dentro de la literatura especializada contemporánea. Objetivo: Ofrecer una visión actual sobre el tratamiento de la odontogeriatría en los planes y programas de estudio en Cuba. Desarrollo: Se realizó una revisión bibliográfica en la literatura científica de los últimos 5 años a la fecha, en idioma español e inglés y se utilizaron preferentemente las bases de datos Ebsco, Pubmed y SciELO. Se consultaron artículos que abordaran la temática de la odontogeriatría en los currículos de estudio del pregrado en la carrera de estomatología y cómo se maneja la especialización desde el posgrado. Se hizo un análisis comparativo del tratamiento de esta disciplina en el ámbito mundial, de modo que se constató la necesidad de actualizar los planes y programas de estudio de la carrera de estomatología en Cuba, en aras de contribuir a una formación más integral del estudiante y de suplir esta carencia en los profesionales de la estomatología. Conclusiones: En Cuba resulta una necesidad, elevar la capacitación del estomatólogo, tanto en el pregrado como en el posgrado, en temas de odontogeriatría, con el fin de procurar una mayor calidad de vida de la población adulta mayor(AU)

Introduction: The aging of the world population in the new millennium favors that attention to the geriatric patient remains a transcendental subject within contemporary specialized literature. Objective: To offer a current vision on the treatment of the Geriatric Dentistry in Cuban plans and study programs. Development: A bibliographic review was carried out assuming the scientific literature of the last 5 years to date, in English and Spanish, using the databases Ebsco, Pubmed and Scielo. There were consulted articles that approached the Geriatric Dentistry thematic in the undergraduate study curricula of the Dentistry career and how the specialization is managed from the postgraduate level. A comparative analysis of the treatment of this Dentistry discipline was carried out worldwide, so the necessity to update the Dentistry study in Cuban plans and programs was confirmed, in order to contribute to a more comprehensive student training and fill this lack in Dentistry professionals. Conclusions: it is a necessity to increase dentists' training about Geriatric Dentistry in Cuban undergraduate and postgraduate studies in order to achieve a higher life quality in older population(AU)

University students' perceived need for mental health services: A study of variables related to not seeking help.

This study analyzed data from the 2012 Student Experience in the Research University (SERU) survey, collected from undergraduate students at 9 universities. Researchers explored how demographic and behavioral variables related to avoidance of psychological help when needed. A total of 7,992 SERU participants responded to target items included in the present study. We examined whether student characteristics and behaviors differed between 3 self-report groups: (1) students who indicated they did not need counseling services; (2) students who reported needing counseling services, but not using them; and (3) students who reported using counseling services at least once during the 2012 academic year. Students who reported needing, but not using, counseling services were significantly different from the other 2 groups in that they were more likely to be female, Hispanic, endorse financial difficulties, and work longer hours while attending school. The 3 groups did not differ in understanding others with observable disabilities. Implications for college counselors and student affairs personnel are discussed. (PsycINFO Database Record

Partial Activation of SA- and JA-Defensive Pathways in Strawberry upon Colletotrichum acutatum Interaction.

Understanding the nature of pathogen host interaction may help improve strawberry (Fragaria × ananassa) cultivars. Plant resistance to pathogenic agents usually operates through a complex network of defense mechanisms mediated by a diverse array of signaling molecules. In strawberry, resistance to a variety of pathogens has been reported to be mostly polygenic and quantitatively inherited, making it difficult to associate molecular markers with disease resistance genes. Colletotrichum acutatum spp. is a major strawberry pathogen, and completely resistant cultivars have not been reported. Moreover, strawberry defense network components and mechanisms remain largely unknown and poorly understood. Assessment of the strawberry response to C. acutatum included a global transcript analysis, and acidic hormones SA and JA measurements were analyzed after challenge with the pathogen. Induction of transcripts corresponding to the SA and JA signaling pathways and key genes controlling major steps within these defense pathways was detected. Accordingly, SA and JA accumulated in strawberry after infection. Contrastingly, induction of several important SA, JA, and oxidative stress-responsive defense genes, including FaPR1-1, FaLOX2, FaJAR1, FaPDF1, and FaGST1, was not detected, which suggests that specific branches in these defense pathways (those leading to FaPR1-2, FaPR2-1, FaPR2-2, FaAOS, FaPR5, and FaPR10) were activated. Our results reveal that specific aspects in SA and JA dependent signaling pathways are activated in strawberry upon interaction with C. acutatum. Certain described defense-associated transcripts related to these two known signaling pathways do not increase in abundance following infection. This finding suggests new insight into a specific putative molecular strategy for defense against this pathogen.

Burnout syndrome in psychotherapists: a comparative analysis of five nations.

Burnout is a common phenomenon among psychotherapists. The purpose of this study was to test the Counselor Burnout Inventory (CBI; Lee et al., 2007) measurement invariance, as well as compare means of five latent variables (i.e., CBI subscales of Exhaustion, Incompetence, Negative Work Environment, Devaluing Client, and Deterioration in Personal Life) across five nations (United States, Korea, Japan, Philippines, and Hong Kong) using structural equation modeling. The results indicated that the assumptions of configural, factor loading, and intercept invariance were satisfied across the five nations. When comparing means of five latent variables, the results indicated differential burnout tendencies across the five nations. Implications for psychotherapists' burnout prevention and future research are discussed.

Autoimmunity in connection with a metal implant: a case of autoimmune/autoinflammatory syndrome induced by adjuvants.

Autoimmune/autoinflammatory syndrome induced by adjuvants (ASIA) has been recently proposed by Shoenfeld and Agmon-Levin as a new entity that comprises several conditions: the macrophagic-myofasciitis syndrome, the Gulf War syndrome, silicosis and post-vaccination phenomena, autoimmunity related to infectious fragments, hormones, aluminum, silicone, squalene oil, and pristane. We report the case of a 23-year-old woman who developed serial episodes of high fever, extreme fatigue, transient thrombocytopenia, multiple cervical adenopathies, hepatosplenomegaly, anemia, neutropenia, severe proteinuria and urine sediment abnormalities, elevated serum ferritin levels, and transient low positive antinuclear antibodies 1 year after she had a nickel-titanium chin implant for cosmetic reasons. The clinical picture simulated a variety of probable diseases: systemic lupus erythematosus, Kikuchi-Fujimoto syndrome, adult onset Still's disease, antiphospholipid syndrome, and hemophagocytic syndrome, among others, so she underwent an extensive medical investigation including two lymph node biopsies. She received treatment accordingly with steroids, methotrexate, and mofetil mycophenolate, with initial improvement of her symptoms, which recurred every time the dose was reduced. Two and a half years later the patient decided to retire the chin implant and afterwards all her systemic symptoms have disappeared. She remains in good health, without recurrence of any symptom and off medications until today. Albeit this patient fulfills proposed major ASIA criteria, to our knowledge it would be the first description of systemic features of autoinflammation in connection with a metal implant.

Optimization of a sponge cake formulation with inulin as fat replacer: structure, physicochemical, and sensory properties.

The effects of several fat replacement levels (0%, 35%, 50%, 70%, and 100%) by inulin in sponge cake microstructure and physicochemical properties were studied. Oil substitution for inulin decreased significantly (P < 0.05) batter viscosity, giving heterogeneous bubbles size distributions as it was observed by light microscopy. Using confocal laser scanning microscopy the fat was observed to be located at the bubbles' interface, enabling an optimum crumb cake structure development during baking. Cryo-SEM micrographs of cake crumbs showed a continuous matrix with embedded starch granules and coated with oil; when fat replacement levels increased, starch granules appeared as detached structures. Cakes with fat replacement up to 70% had a high crumb air cell values; they were softer and rated as acceptable by an untrained sensory panel (n = 51). So, the reformulation of a standard sponge cake recipe to obtain a new product with additional health benefits and accepted by consumers is achieved. Practical Application: In this study, fat is replaced by inulin in cakes, which is a fiber mainly obtained from chicory roots. Sponge cake formulations with reductions in fat content up to 70% are achieved. These high-quality products can be labeled as "reduced in fat" according to U.S. FDA (2009) and EU regulations (European-Union 2006).

A reliability generalization study of the Frost Multidimensional Perfectionism Scale (F-MPS).

Perfectionism has been identified as a common concern among clients who seek counseling services. For more than 20 years, the Frost Multidimensional Perfectionism Scale (F-MPS) has been used extensively to measure the construct of individuals' perfectionism. The current study used reliability generalization to identify the average score reliability as well as variables explaining the variability of score reliability. Typical reliability across subscale scores ranged from .71 to.86 with the Doubt about Action subscale showing the least variability and the Organization subscale showing the most. In addition, sex, language, and standard deviation of the scale had statistically significant relations to reliability estimates.

Gonadotropinas (LH y FSH) y corticotropina (ACTH) / Gonadotropins (LH and FSH) and adrenocorticotropin (ACTH)

Las gonadotropinas (LH y FSH) y la corticotropina (ACTH) son hormonas hipofisarias reguladas por los factores hipotalámicos correspondientes. Las gonadotropinas regulan la función gonadal masculina y femenina, así como la síntesis de las hormonas sexuales. Su cuantificación se realiza por inmunoanálisis tanto basal como en respuesta a estímulos de análogos de la Gn-RH. Su estudio es útil en el diagnóstico de la pubertad precoz, en los hipogonadismos y en las diversas afecciones del eje hipotálamo-hipofiso-gonadal. La corticotropina es otro péptido de origen hipofisario que ejerce su acción sobre la corteza suprarrenal estimulando la esteroidogénesis. Se secreta de forma pulsátil y presenta un ritmo circadiano característico, con un máximo de secreción por la mañana. La corta vida media, su inestabilidad, los tratamientos con corticoides y su vulnerabilidad a las enzimas celulares son factores a tener en cuenta en su valoración. Su cuantificación en plasma se realiza por inmunoanálisis, y su derivado sintético (ACTH 1-24) se utiliza como estímulo farmacológico para el estudio de la función hipotálamo-hipofiso-suprarrenal. Aunque el test de referencia es la hipoglucemia insulínica, por sus dificultades y contraindicaciones el test de estimulación con ACTH 1-24 se considera un método indirecto de detección de las alteraciones hipotálamo-hipofisarias. También ha sido utilizado para valorar la actividad enzimática suprarrenal y sus alteraciones congénitas, como la hiperplasia suprarrenal congénita (HSC) o adquirida. La participación del laboratorio hormonal es de gran utilidad en el diagnóstico de las enfermedades que afectan a dichos péptidos (AU)

Gonadotropins (LH and FSH) and adrenocorticotropin (ACTH) are pituitary hormones regulated by the corresponding hypothalamic releasing factors. Gonadotropins are the main regulators of male and female gonadal functions and sexual hormone synthesis. Laboratory assessment of LH and FSH can be basal or stimulated by GnRH analogs, using immunoassay methods. In precocious puberty, hypogonadism or other pathological conditions affecting hypothalamic-pituitary-gonadal axis, LH and FSH measurement are useful and sensitive alone or together with sexual hormones (testosterone and estradiol) in order to establish the diagnosis. Corticotropin (ACTH) is another pituitary hormone which regulates adrenal steroid synthesis. Hormone release is pulsatil throughout the day, but exhibits a diurnal pattern with levels being the highest in the early morning. ACTH secretion increases in response to hypocortisolemia if the hypothalamus and pituitary gland are intact. Numerous factors affect interpretation of the ACTH test, including half-life, stability, glucocorticoid administration and vulnerability to cellular enzymes all of which must be taken into account. Immunoassay methods are reliable and different tests can be used to study hypothalamic-pituitary-adrenal axis secondary to deficiency or hyperfunction. Hormonal laboratory assessment has a valuable role to establish the diagnosis of the diseases affecting these peptides (AU)

Validación de un ELISA tipo inhibición para cuantificar polisacárido Vi en la vacuna antitifoídica cubana vax-TyVi / Validation of an inhibition-type ELISA for quantifying Vi polysaccharide content in the Cuban

Se describe la validación de un ELISA tipo inhibición, reportado por primera vez en la literatura científica para cuantificar un antígeno vacunal: el polisacárido Vi de Salmonella Typhi, para ser empleado en el control de la calidad de la vacuna antitifoídica cubana vax-TyVi‚. El ensayo consta de seis pasos: 1) Recubrimiento de placa de reacción con poli-L-lisina y posteriormente polisacárido Vi; 2) Bloqueo con leche descremada; 3) Inhibición o neutralización en tubos de suero anti-Vi de conejo, respectivamente, con polisacárido Vi de Curva de Calibración (concentraciones desde 1–32 µg/mL), control positivo y muestras de vacuna (3 diluciones); 4) Neutralización de anticuerpos anti-Vi libres, presentes en las mezclas anteriores, por el Polisacárido de Recubrimiento; 5) Reconocimiento de anticuerpos anti-Vi unidos a la placa (conjugado anti-IgG de conejo-fosfatasa alcalina) y 6) Revelado por reacción enzima-sustrato. Los parámetros de validación estudiados y sus resultados fueron: 1) Precisión, expresada como coeficiente de variación a tres niveles de concentración de polisacárido, comprendidos en el rango de su especificación (35, 50 y 70 µg/mL) y evaluada en términos de repetibilidad; precisión intraensayos (cuatro analistas) y reproducibilidad (seis analistas): £ 20por ciento; 2) Linealidad (100*R2): 99,68 por ciento; 3) Límite de detección: 0,5 µg/mL; 4) Exactitud (recuperación para las tres diluciones de la muestra: entre 100 y 118por ciento), y 5) Robustez: no influye 1,5 h de bloqueo (p = 0,52) ni ± 5 min para leer placa (p = 0,56); influye grandemente la calidad del agua (p = 0,026), a favor del agua para inyección. El ensayo es adecuado para los fines propuestos y es una medida de la inmunogenicidad in vitro del polisacárido Vi(AU)
