Simulation model to assess the validity of the clinical portfolio diet score used in the PortfolioDiet.app for dietary self-tracking: a secondary analysis of a randomized controlled trial in hyperlipidemic adults.

Introduction: The Portfolio Diet combines cholesterol-lowering plant foods for the management of cardiovascular disease risk. However, the translation of this dietary approach into clinical practice necessitates a user-friendly method for patients to autonomously monitor their adherence. Objective: This study aimed to develop and validate the clinical-Portfolio Diet Score (c-PDS) as a food-based metric to facilitate self-tracking of the Portfolio Diet. Methods: Using a simulation model to estimate the c-PDS, the validity was assessed in a secondary analysis of a completed trial of the Portfolio Diet in 98 participants with hyperlipidemia over 6 months. Concurrent and predictive validity of the estimated c-PDS were assessed against the reference measure (weighed 7-day diet records) and concomitant changes in LDL-C from baseline to 6 months. Bland-Altman analysis was used to assess the limits of agreement between the two methods. Results: The c-PDS was positively correlated with dietary adherence as measured using the 7-day diet records (r = 0.94, p < 0.001). The c-PDS was negatively correlated with change in LDL-C (r = -0.43, p < 0.001) with a 1-point increase in the c-PDS being associated with a - 0.04 mmol/L (CI:-0.06,-0.03; p < 0.001) or a 1.09% reduction in LDL-C. Visual evaluation of the Bland-Altman plots showed reasonable agreement. Conclusion: These findings indicate good validity of the c-PDS for primary prevention in adults with hyperlipidemia. The predictive validity findings have informed the goals and messaging within the PortfolioDiet.app, a digital health application for delivering the Portfolio Diet. Future research will assess the effectiveness of the intended combination of the c-PDS and the PortfolioDiet.app in supporting behavior change.

Teaching Father-Infant Massage during Postpartum Hospitalization: A Randomized Crossover Trial.

PURPOSE: The purpose of this study was to evaluate acceptability and impact of infant massage video instruction on fathers' behaviors in early postpartum. METHODS: A randomized crossover design was used. Participants were fathers of healthy term infants born at a Magnet hospital in Southern California. Measures included a demographic survey, Father-to-Infant Bonding Scale, Father-Infant Observation Scale, and postdischarge phone interview. Study nurses observed father-infant interactions for 5 minutes. Fathers were randomized to one of two groups: fathers in group 1 saw the massage video before they were observed with their infants and fathers in group 2 saw the video after. Fathers completed the Bonding Scale at baseline in person and again within a week of discharge by phone. Statistics were descriptive and comparative. Responses to interview questions were categorized and described. RESULTS: Ninety-eight fathers aged 18 to 44 years participated. Over half of fathers identified as Hispanic and the majority spoke English at home. Most fathers had positive responses to infants on individual Bonding Scale items. Fathers differed significantly in observed interactions with infants depending upon timing of massage instruction; fathers observed immediately after the video had more total interactions, specifically fingertip touching. Poststudy evaluations were predominantly positive. CLINICAL IMPLICATIONS: We found a brief infant massage instruction offered by video was well accepted by fathers and increased observed father-infant interactions.

Evaluation of the exposure to coal dust and prevalence of pneumoconiosis in underground mining in three Colombian departments / Evaluación de la exposición al polvo de carbón y de sílice en sitios de minería subterránea en tres departamentos de Colombia

Introduction: Coal workers' pneumoconiosis is a chronic and irreversible disease representing a public health problem. Objective: To estimate the prevalence of pneumoconiosis and its associated factors among underground coal miners in the Colombian departments of Boyacá, Cundinamarca and Norte de Santander. Materials and methods: We conducted a cross-sectional study of 476 miners to measure the prevalence of pneumoconiosis and its associated factors such as coal dust and silica levels, as well as the occupational conditions. The medical assessment and a chest x-ray were performed according to the International Labor Organization criteria, along with spirometry and the identification of glutathione S-transferase and repair enzyme polymorphisms.The associations were explored using Cox regression models. Results: We performed a total of 479 environmental monitoring sessions in 31 companies and we evaluated 476 workers with 10 to 57 years of mining work experience. The prevalence of pneumoconiosis was 33.8% (95% CI: 27.0 - 41.3%). In the Cox multivariate regression model with a constant risk time, pneumoconiosis was significantly associated with working in medium-sized companies (PR=2.00, 95% CI: 0.995 - 2.690; p=0.052), the level of severe exposure to coal dust (PR=2.055, 95% CI: 1.043 - 4.048; p=0.038), and working in underground mining for 25 years or more (for those with 25.0-29.9 years: PR=2.199, 95% CI: 1.449 - 3.338; p=0.001). Conclusions: The prevalence of pneumoconiosis was very high and was found to be associated with severe exposure to coal dust, work exposure for 25 years or more and working in medium-sized enterprises

Introducción. La neumoconiosis de mineros del carbón es una enfermedad crónica e irreversible que se considera un problema de salud pública. Objetivo. Estimar la prevalencia de neumoconiosis y sus factores asociados en mineros de carbón de Boyacá, Cundinamarca y Norte de Santander. Materiales y métodos. Se hizo un estudio de corte transversal en 476 mineros. Se les hizo valoración médica, se tomaron radiografías de tórax siguiendo los criterios de la Organización Internacional del Trabajo, así como espirometrías, y se identificaron los polimorfismos de la glutatión S-transferasa y de las enzimas de reparación. Las asociaciones entre las condiciones ocupacionales y de la empresa con la neumoconiosis, se estudiaron usando modelos de regresión de Cox. Resultados. En 31 empresas se hicieron 479 monitorizaciones ambientales y se evaluaron 476 trabajadores cuyo tiempo de trabajo fluctuaba entre 10 y 57 años. La prevalencia de la neumoconiosis fue de 33,8 % (IC95% 27,0-41,3). En el modelo de regresión multivariado de Cox, con tiempo de riesgo constante para la neumoconiosis, esta se asoció significativamente con el trabajo en empresas medianas (razón de prevalencias, RP=2,00; IC95% 0,995- 2,690; p=0,052), con un nivel alto de exposición al polvo de carbón según el índice de exposición (RP=2,055; IC95% 1,043-4,048; p=0,038), y una antigüedad de 25 años o más (para 25,0 a 29,9 años: RP=2,199; IC95% 1,449-3,338; p=0,001). Conclusiones. La prevalencia de la neumoconiosis fue muy alta y se asoció a la exposición a altos niveles de polvo de carbón, a una exposición laboral mayor o igual a 25 años y al trabajo en empresas medianas.

The care of the actively dying in an academic medical center: a survey of registered nurses' professional capability and comfort.

BACKGROUND: Care of the dying is a significant component of nursing practice particularly in hospitals. Nurses who work in certain areas like oncology, intensive care unit (ICU) face the care of the dying, more so than other units. OBJECTIVES: The survey was conducted to assess nurses' self-perception of their professional capability and comfort in the care of the actively dying. Determine if professional capability and comfort was associated with any of the six demographics characteristics (age, gender, clinical experience, education level, nursing unit, continuing education). Identify areas of clinical challenge to promote educational initiatives to stimulate best nursing practice in the actively dying. DESIGN: The survey comprised of two parts: Part I with demographic characteristics and a single open-ended question, Part II with twenty questions on the domains recommended by the NCP. RESULTS: Older age and greater clinical experience were associated with greater levels of capability/comfort. Most nurses felt professionally capable and comfortable in domains such as knowledge, physical and psychosocial care but bioethics, communication, cultural, spiritual and bereavement issues challenged ≥ 40%. CONCLUSIONS: Nurses self-perceived professional capability and comfort levels in caring for the dying were positively influenced by older age, greater clinical experience and extensive continuing education. Bioethics, communication and grief impacted nurses personally and emotionally. Continuing education, organized debriefing, grief-counseling, and preceptors support should be routine for nurses who work in units with predictable high mortality.

Introduction: coal miners' pneumoconiosis is an occupational lung disease associated with individual factors and specific working conditions. It is manifested progressively and irreversibly, affecting the health of workers and labor productivity. Objective: To characterize the respiratory health conditions and identify risk factors associated with the development of pneumoconiosis in workers that have been exposed to coal dust in the underground mines at Boyacá, 2013. Materials and Methods: A descriptive cross-sectional study was conducted among mining workers exposed to coal dust in the department of Boyacá. It was conducted a complete record of occupational medical history, physical exam, taking chest radiography, tuberculin test and spirometry. Results: 170 male workers participated. 75% of the population had worked in the mining sector for more than12.5 years old. Rhonchi, wheezing and rattling predominated in workers over 20 years old. Expectoration and cough were most frequently found in those who made mechanized extraction. 15.9% of chest X rays were compatible with pneumoconiosis, 17.1% of tuberculin tests were found positive. 5.3% of spirometries showed peripheral airway abnormalities and 2.4% showed obstructive pattern. Discussion and conclusion: Radiological changes suggestive of pneumoconiosis were more frequent in workers under 20 years old. Abnormal spirometric findings predominated in the group with more than 20 years old. It is important to review surveillance protocols and perform monitoring through occupational medicine.

Estudo da representaçäo social do enfermeiro recém-formado em seu primeiro emprego e suas expectativas em relaçäo ao programa de orientaçäo / Study of the social representations of the new graduate in relation to their first job

Um bom programa de orientaçäo existente em uma instituiçäo hospitalar é a base para a garantia da boa qualidade da assistência ao paciente, na estabilidade emocional e na segurança de que um profissional recém-admitido precisa para desempenhar suas atividades e adaptar-se ao novo emprego. Isso é de fundamental importância para que ele se familiarize mais rapidamente com os objetivos e a filosofia da instituiçäo, bem como com sua planta física e com os novos colegas. Entretanto, na literatura sobre educaçäo continuada e educaçäo em serviço, encontra-se muito pouco sobre a situaçäo do recém-formado no seu primeiro emprego. Em funçäo disso, elaborou-se esta pesquisa com os objetivos de identificar a representaçäo social do enfermeiro recém-formado em relaçäo ao seu primeiro emprego; identificar o tipo de programa de orientaçäo (PO) oferecido pela instituiçäo hospitalar ao enfermeiro recém-formado; verificar a relaçäo entre a representaçäo social do enfermeiro e o programa de orientaçäo oferecido. Os dados foram coletados em seis hospitais com programa de orientaçäo para os enfermeiros recém-admitidos e dois hospitais sem programa formal de orientaçäo para os enfermeiros recém-admitidos. No presente trabalho, foram analisadas as expectativas do enfermeiro recém-formado em seu primeiro emprego, bem como os diferentes PO que säo oferecidos ao enfermeiro recém-admitido. A metodologia utilizada permitiu concluir que há: dificuldades no relacionamento com os funcionários, por causa da inexperiência do recém-admitido; dificuldades no desenvolvimento do trabalho, pela existência de um número muito grande de pacientes; dificuldades de enfrentamento da realidade, por causa da falta de continuidade e de ligaçäo entre os conhecimentos adquiridos na faculdade e os problemas encontrados no hospital; falta de orientaçäo por parte da chefia, que, no entanto, alega ter orientado bem o recém-admitido. Com relaçäo aos enfermeiros que näo receberam orientaçäo formal constatou-se que atendem mais as intercorrências administrativas do que as assistenciais diretas ao paciente. Com relaçäo aos enfermeiros que receberam orientaçäo constatou-se que näo há condiçöes práticas para aplicar o que se discute no PO: faltam reuniöes, desenvolvimento de funcionários, cooperaçäo dos colegas, entre outros; näo dominam técnicas e procedimentos comuns; as condiçöes financeiras das instituiçöes geram más condiçöes de trabalho. Quanto às instituiçöes estudadas que mantém PO verificou-se que apenas uma o tinha de maneira formal, sob a responsabilidade de enfermeiros com competência específica, enquanto que as outras instituiçöes faziam orientaçäo verbal, muitas vezes mal planejada e algumas sem planejamento. Identificou-se, ainda, que os enfermeiros que receberam orientaçäo relatam maior número de insatisfaçöes do que de satisfaçöes. Isso provavelmente se deve ao fato de que, tendo conhecido a forma como devem ser desenvolvidas as suas atividades, esses profissionais passaram a identificar os problemas mais rapidamente que os outros, que näo receberam orientaçäo, por terem visäo crítica das condiçöes da instituiçäo e do próprio trabalho.
