Attitudes and experiences related to the deaths of COVID-19 patients among nursing staff: A qualitative evidence synthesis.

AIM: To identify and synthesize the experiences and attitudes of nursing staff regarding the deaths of COVID-19 patients. REVIEW METHODS: A qualitative evidence synthesis was carried out, using Noblit and Hare's meta-ethnographic approach. The review protocol was listed in PROSPERO (CRD42022330928). Studies published from January 2020 to January 2022 that met the criteria were searched in PubMed, Web of Science, Scopus, CINAHL, CUIDEN and PsycInfo. A total of 12 articles were included. RESULTS: Thirty-three metaphors emerged, which were grouped into three main themes: Determining factors of care, Feelings about death and Strategies for coping with death. Nurses reported the high emotional toll, the absence of family and the lack of staff, protocol and training as determining factors. Furthermore, staff had doubts about the quality of care that COVID-19 patients received. As coping strategies, nurses developed avoidance behaviours towards COVID-19 patients, selective memories, resilience, and/or leaving the profession. CONCLUSIONS: The difficulty in providing adequate nursing care and the high number of deaths has increased anxiety and stress among nurses. These factors, alongside their lived experiences of seeing patients suffering, many dying alone without family members, have had psychological repercussions on nursing staff. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The results demonstrate a high emotional toll and doubts surrounding their caregiving role caused by the lack of professional training needed to face a pandemic. This research shows what has been learned for future pandemics and highlights basic components that could provide a foundation for coping interventions for healthcare professionals. IMPACT: WHAT PROBLEM DID THE STUDY ADDRESS?: The challenges posed by COVID-19 patient deaths for nursing staff around the world and also by the pandemic circumstances in which those deaths occurred. WHAT WERE THE MAIN FINDINGS?: The high number of deceased patients who were isolated from family members, communication with family members and doubts surrounding care given during the pandemic have created feelings of fear, stress and anxiety, as well as obsessive thoughts that have changed nursing staff's perception of death due to COVID-19. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: Results will be useful for preparing for future pandemics, and for policymakers and health staff in supporting healthcare professionals by creating programmes to help them cope with the emotional toll they have felt after dealing with death in such unprecedented circumstances. REPORTING METHOD: The authors have adhered to the PRISMA guidelines and the eMERGe Reporting Guidance. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Efficacy of gel containing organic extra virgin olive oil for peristomal skin hygiene: A pilot randomised controlled trial.

AIM: To assess the efficacy and safety of the application, during stoma hygiene, of a pH-neutral gel containing organic EVOO (oEVOO) for the maintenance of peristomal skin integrity. METHOD: Patients with a colostomy or ileostomy were enrolled in a pilot randomized controlled trial and assigned treatment with a pH-neutral gel made from natural products including oEVOO or usual stoma hygiene gel. The primary outcome was three domains of abnormal peristomal skin: Discolouration, Erosion and Tissue overgrowth. Secondary outcomes that were evaluated included skin moisture; oiliness; skin elasticity; water-oil balance; patients' perceptions; difficulty inserting and removing the pouching system; pain, any other chemical, infectious, mechanical, or immunological complications of concern. The intervention lasted 8 weeks. RESULTS: Twenty-one patients were recruited for the trial and randomly assigned to either the experimental group (n = 12) or the control group (n = 9). The groups did not differ significantly in terms of patient characteristics. No significant differences between groups were identified either at baseline (p = 0.203) or at the end of the intervention (p = 0.397). In the experimental group, domains of abnormal peristomal skin improved after the intervention. The difference observed before and after the intervention was statistically significant (p = 0.031). CONCLUSION: The use of a gel containing oEVOO has shown similar levels of efficacy and safety to other gels commonly used for peristomal skin hygiene. It is also relevant to highlight that a significant improvement in skin condition was observed in the experimental group before and after the intervention.

Severe gastritis in a patient treated with immunotherapy: immune-mediated or reactivation of cytomegalovirus?

Cancer patients receiving programmed death 1 (PD-1) immune checkpoint blockade therapy are susceptible, due to immunosuppression, to a variety of infections including cytomegalovirus infection. We report an unusual case of histologically confirmed gastritis due to cytomegalovirus infection in a patient who had metastatic melanoma and received PD-1 blockade therapy with pembrolizumab. Pembrolizumab was discontinued and treatment with intravenous ganciclovir and oral vangaciclovir was initiated; the patient's symptoms improved significantly.

Lifetime Dual Disorder Screening and Treatment Retention: A Pilot Cohort Study.

The coexistence of a substance use disorder and another mental disorder in the same individual has been called dual disorder or dual diagnosis. This study aimed to examine the prevalence of lifetime dual disorder in individuals with alcohol or cocaine use disorder and their retention in treatment. We conducted a pilot cohort study of individuals (n = 1356) with alcohol or cocaine use disorder admitted to treatment in the public outpatient services of Barcelona (Spain) from January 2015 to August 2017 (followed-up until February 2018). Descriptive statistics, Kaplan−Meier survival curves and a multivariable Cox regression model were estimated. The lifetime prevalence of screening positive for dual disorder was 74%. At 1 year of follow-up, >75% of the cohort remained in treatment. On multivariable analysis, the factors associated with treatment dropout were a positive screening for lifetime dual disorder (HR = 1.26; 95% CI = 1.00−1.60), alcohol use (HR = 1.35; 95% CI = 1.04−1.77), polysubstance use (alcohol or cocaine and cannabis use) (HR = 1.60; 95% CI = 1.03−2.49) and living alone (HR = 1.34; 95% CI = 1.04−1.72). Lifetime dual disorder is a prevalent issue among individuals with alcohol or cocaine use disorders and could influence their dropout from treatment in public outpatient drug dependence care centres, along with alcohol use, polysubstance use and social conditions, such as living alone. We need a large-scale study with prolonged follow-up to confirm these preliminary results.

Assessment of Health Indicators in Individuals with Intestinal Stoma using the Nursing Outcomes Classification: A Cross-Sectional Study.

Aim: To determine nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. Design: Cross-sectional study performed with 102 subjects at the General Surgery Unit of a first-level hospital. Methods: Data on the presence of nursing outcomes were collected using the Nursing Outcomes Classification. Data on sociodemographic and clinical variables were also collected. Univariate and bivariate data analyses were performed. Results: Outcomes related to participation in making health decisions and knowledge of ostomy care were assessed across the study sample. Period of care (post-operative and follow-up) was the most common significant variable (p < 0.05) among the outcomes. The outcome scores ranged from 2 to 3, indicating a moderate level of impairment in the physical, psychological, and social spheres of these patients. The scores in the indicators on Participation in making health decisions and Knowledge of stoma care improved in the period of continuity of care compared to the postoperative period, being this difference statistically significant (p < 0.001). Conclusions: The care plan for individuals with intestinal stoma needs to include indicators measuring patient participation in making decisions related to their condition, as well as indicators related to their knowledge and self-care of their stoma. Relevance to clinical practice: This study aims to determine the nursing outcomes in individuals with intestinal stoma and the relationships between them and sociodemographic and clinical variables. It provides the opportunity to plan achievable objectives with patients using a system of indicators that facilitate their assessment and monitoring.

Evaluation of interventions in people with digestive stoma through the Nursing Interventions Classification.

PURPOSE: To determine which nursing interventions are used in individuals with a digestive stoma and the relationships between nursing interventions used and sociodemographic and clinical variables. METHODS: The present study is an observational, cross-sectional, descriptive. Data from 102 individuals in the general surgery unit of a first-level hospital (University Hospital Complex of Granada, Spain) were analyzed. Data on the use of nursing interventions and sociodemographic and clinical variables were collected. Univariate, bivariate, and multivariate data analyses were conducted. FINDINGS: Interventions: Decision-Making Support (5250) and Ostomy Care (0480) were the most prevalent interventions in the sample. The period of care (postoperative and follow-up) was the most common significant variable (p < 0.05) among the interventions observed. Anxiety Reduction (5820), Nutritional Counseling (5246), Self-Esteem Enhancement (5400), and Body Image Enhancement (5220) were also relevant findings. CONCLUSIONS: The present study contributes to determining which nursing interventions are used in individuals with a digestive stoma. IMPLICATIONS FOR NURSING PRACTICE: This study could be useful in planning nursing interventions in individuals with a digestive stoma.

Bibliometric analysis of qualitative research on patients' experiences of intestinal stoma published between 2002 - 2018.

AIMS: The purpose of this paper was to perform a bibliometric analysis of the production of qualitative research in scientific journals through aggregation by levels and to identify factors of diversity, such as types of designs, in qualitative research on the experience of having an intestinal stoma between 2002 and 2018. DESIGN: Descriptive bibliometric study focused on the production of qualitative research on the subject of study, on three levels: micro, meso and macro. METHODS: Databases such as PubMed, CINAHL, Web of Knowledge, Scopus, SciELO, CUIDEN, Lilacs and Google Scholar were used to collect the data, between August - November 2018. RESULTS: Nursing was the main area of knowledge. Brazil was the predominant country of origin. The most productive journal was the Journal of Wound, Ostomy & Continence Nursing. English and Portuguese were the main languages of scientific communication. The number of authors was typically between 2 and 6. Authors conducted descriptive and phenomenological studies. CONCLUSION: The present bibliometric study helps us to map the qualitative research on the experiences of individuals with an intestinal stoma and to understand patterns in the designs, methods, disciplines and journals involved in this area of research. This will allow nurses to have a leading contribution to stoma care at their disposal.

Experiences and Attitudes of People with HIV/AIDS: A Systematic Review of Qualitative Studies.

The aim of this article was to explore the experiences and attitudes of people with HIV/AIDS. A systematic review of qualitative studies was carried out. Twenty-seven articles were included, with sample sizes ranging from 3 to 78. Articles from North America, South America, Central America, Europe, and Africa were included. Five topics emerged from the synthesis: feelings about the diagnosis of HIV/AIDS; stigma and HIV/AIDS; changes in sexual behavior after becoming infected; living with the virus; and pregnancy and motherhood in seropositive women. The moment of diagnosis is of vital importance for these people due to feelings such as disappointment, sadness, fear, despair, lack of awareness, and pain. Social support is highly valued among these people and is linked to an improvement in these peoples' quality of life. Different kinds of stigma accompany people with HIV/AIDS throughout their life, like social stigma, self-stigma, and health professionals' stigma. Seropositive women who decide to become mothers can feel frustration because they cannot breastfeed. Spirituality helps some people to deal with the fact of being a virus or disease carrier.

Impulsiveness and Cognitive Patterns. Understanding the Perfectionistic Responses in Spanish Competitive Junior Athletes.

INTRODUCTION: High performance sport requires that the athletes maintain a constant intensity and control of their personal resources, as well as a balance between self-regulation and performance. Likely, such requirements involve the influence of their beliefs regarding the tasks to be performed to improve the confidence in their own resources to face the competition. Theoretical arguments provide new insights for understanding multidimensional perfectionism and its relationships with other variables such as affective experiences, among others. In this study, perfectionism was conceptualized as a "stable personality disposition," whereas the impulsiveness components were defined as "representing psychological mechanisms (or processes)" underlying the relationships between perfectionism and athletic experiences. AIM: This study aims to establish and show profiles of perfectionist beliefs and impulsive responses according to sport modality and the relationships between all these variables. Team athletes were expected to show more functional resources than those in combat or endurance sports. METHODS: The psychological responses of 487 athletes (273 boys; 214 girls) practicing high-performance sport were examined. A non-randomized, cross-sectional design was used. Self-reports were used to measure impulsiveness, perfectionism and competence self-perceptions. RESULTS: Athletes with functional responses of impulsivity and perfectionism showed higher perceived self-competence. Athletes with more reflective thoughts, more careful planning and generally less sensitive to rewards and behaviors were more self-regulated and planned (functional impulsivity) and showed more moderate relationships between the most dysfunctional perfectionist beliefs and self-competence. In addition, perfectionism seems to be useful to the striver athletes that want to be the best, and they are focused on and committed to future goals and performance and self-improvement. It is important for coaches and athletes to understand how the processes of self-regulation (impulsivity) and self-knowledge (perfectionism) could be formed to try to offer better opportunities for building psychological resources that enhance high-performance mental abilities.

Living With an Intestinal Stoma: A Qualitative Systematic Review.

The main aim of this article is to explore the experiences and life situations of people living with intestinal stomas. Previous studies indicated the need to investigate the concerns of ostomy patients and how these concerns can affect their quality of life and their approaches to the comprehensive conceptualization of the bodily changes. A qualitative systematic review and metasynthesis design was carried out by using the main scientific databases. Original articles from 2002 to 2015 were selected based on their qualitative methodology. Methodological quality was evaluated using the Critical Appraisal Skills Program. The findings were synthesized using the metasynthesis procedure of Sandelowski. The final number of articles included was 95 and 1,982 participants. Regarding the metasummary, the data generated 191 thematic statements that were organized into eight categories. The findings support an explanatory model of the experience of people with ostomy based on three aspects: Acceptance, Adaptation, and Autonomy.

Nursing Diagnoses in People with Digestive Stoma and their Association with Sociodemographic and Clinical Factors.

PURPOSE: To determine nursing diagnoses in people with a digestive stoma and their relationship with sociodemographic and clinical variables. METHOD: A cross-sectional descriptive study of 102 subjects in the General Surgery Unit of a first-level hospital (Granada, Spain) was conducted. Data were collected on the presence of nursing diagnoses, sociodemographic and clinical variables. RESULTS: NANDA-I: "Deficient knowledge (00126)" and "Readiness for enhanced health management (00162)" were present in the entire sample studied. The period of care (postoperative vs. follow-up) was the most common significant variable among diagnoses. CONCLUSIONS: This work contributes to the determination of NANDA-I diagnoses in people with digestive stomas. IMPLICATIONS FOR NURSING PRACTICE: The results provide a guide to help nursing professionals develop individual care plans.

Ostomy patients' perception of the health care received.

AIM: to describe ostomy patient's perception about health care received, as well as their needs and suggestions for healthcare system improvement. METHOD: qualitative phenomenological study was conducted, involving individual and semi-structured interviews on the life experiences of 21 adults who had a digestive stoma. Participants were selected following a purposive sampling approach. The analysis was based on the constant comparison of the data, the progressive incorporation of subjects and triangulation among researchers and stoma therapy nurses. The software Atlas.ti was used. RESULTS: perception of health care received is closely related to the information process, as well as training for caring the stoma from peristomal skin to diet. It is worthy to point out the work performed by stoma care nurses ensuring support during all stages of the process. CONCLUSION: findings contribute to address the main patients' needs (better prepared nurses, shorter waiting lists, information about sexual relation, inclusion of family members all along the process) and recommendations for improving health care to facilitate their adaptation to a new status of having a digestive stoma.

Involvement of Spanish pulmonology centers in patient care, postgraduate education and research in asthma: the results of the ATENEA survey.

UNLABELLED: Although asthma is one of the most prevalent chronic respiratory diseases, the participation of Spanish pulmonology units in the management of asthma may have room for improvement. OBJECTIVE: To determine the degree of involvement of the Spanish pulmonology services in the patient care, education and research related with asthma disease and especially in difficult-to-control asthma. METHODS: A survey made up of 75 questions was sent to the heads of several pulmonology departments. The survey asked questions pertaining to respiratory disease care in general, and in asthma in particular, as well as the educational activities and research in asthma during the previous five years. RESULTS: Out of the 107 surveys sent, 69 (645%) centers filled them out and returned them. Forty-seven (681%) met the criteria for an important level of health-care activity in asthma. However, only 29 (42%) had a monographic consultation for difficult-to-control asthma and 37 (536%) used an education program. As for postgraduate education, only 31 (449%) provided their resident physicians with specific asthma training. And in the research field, 12 (174%) reported having projects funded by SEPAR and 25 (362%) had published studies in journals with an impact factor. CONCLUSIONS: Although the majority of the pulmonology centers interviewed report a notable activity in asthma patient care, their involvement in the specialized approach for difficult-to-control asthma is insufficient. Likewise, participation in educational activities and research related with the disease is inconsistent and limited to few centers.

[Assessment of results in the early diagnosis of breast cancer program in Asturias Community]. / Evaluación de resultados en el programa de detección precoz del cáncer de mama del Principado de Asturias.

OBJECTIVE: To evaluate and disseminate the intermediate results of a breast cancer early detection program in the Asturias Community. MATERIAL AND METHODS: We report the results of screening examinations performed between 2005 and 2009, using the indicators proposed in the European Guidelines on Quality Assurance in Mammography Screening. The information sources for breast cancer cases diagnosed were the pathology information system and the information on the characteristics of the tumour from the pathology report. The classification of the diagnostic features of the program was from its own information system. RESULTS: A total of 1,384 breast cancers were diagnosed in the program target population during the study period, of which 49% were diagnosed in the program, 13% were interval cancers, 17% were diagnosed in women who chose not to participate in the program, and 22% in women who for various reasons had not been invited to participate. The most advanced diagnoses were made in the group of interval cancers and the earliest diagnoses were made in the uninvited population. CONCLUSIONS: When the healthcare system is directed towards the asymptomatic population to provide a measure of prevention, it must ensure that there is a favourable balance. The results of this evaluation are consistent with accepted standards and with those found in other assessments.

[Validation of the ICE model to assess social class in the adult population]. / Validación del modelo REI para medir la clase social en población adulta.

BACKGROUND: Social class has commonly been defined by the type of employment and it is assessed as a categorical variable. However, this approach has a number of drawbacks. The objective of this article is to develop and validate a readily standardizable quantitative indicator of social class and to show its ability to measure the impact of social class as a health determinant. METHODS: In 6729 individuals we measured income, crowding index, education, occupation and employment status. Two models were adjusted to study the neighborhood, dietary pattern and health problems. RESULTS: The model that included only income, crowding index and education (ICE) yielded an indicator that correlated with age (r = -0.28; p < 0.001) and consumption of potatoes (r = -0.17; p < 0.001) and salads (r = 0.10; p < 0.001). This indicator estimated that poor social classes were at significant risk for unemployment (OR = 5,), blue collar jobs (OR = 40,9), residing in poor neighborhoods (OR = 30.2), low salad consumption (OR = 2.2) and high consumption of potatoes (OR = 4.5). They also had, especially in women, a higher risk of sedentarism (OR = 1.8), obesity (OR = 4.4), metabolic syndrome (OR = 3.4) and diabetes mellitus (OR = 2.0). CONCLUSIONS: The ICE index was valid, not based on occupation or employment status, readily standardizable, and suitable for measuring social class and its impact of on health.

Purificación del factor IX recombinante expresado en leche de cerdas transgénicas / Purification of recombinant factor IX expressed in milk of transgenic sows

Se purificó a partir de la leche de cerdas transgénicas, factor IX recombinante, y se obtuvieron rendimientos entre 1 a 2 g de esta proteína por litro, lo que resulta una nueva vía para la obtención de este producto con una alta eficiencia, ya que su expresión es 1 000 veces superior a la del factor IX plasmático humano. Mediante la combinación de 2 pasos cromatográficos: intercambio iónico en DEAE-Shephadex A-50 y cromatografía de afinidad con heparina, se realizó la purificación del factor IX, con esta leche como material de partida. Se estudiaron diferentes métodos para la eliminación de las caseínas, contaminante principal del proceso, y se escogió finalmente la ultracentrifugación, por las numerosas ventajas que presenta con respecto a la precipitación isoeléctrica y la precipitación por sales. El factor IX puede ser purificado de la leche transgénica con una alta pureza utilizando métodos cromatográficos que no usan inmunoafinidad y son finalmente escalables en la producción industrial, lo cual proporciona nuevas perspectivas para el tratamiento de la hemofilia B mediante la preparación de posibles formulaciones orales.

Recombinant factor IX was purified from milk of transgenic sows, and yieldings between 1 and 2 g of this protein per liter were obtained. This is a new way to get this product with a high efficiency, since its expression is 1 000 times higher than of the human plasmatic factor IX. By combining 2 chromatographic steps (ion exchange in DEAE-Shephadex A-50 and affinity chromatography with heparin), the factor IX was purified, with this milk as a starting material. Different methods were studied to eliminate caseins, the main pollutant of the process, and ultracentrifugation was selected due to its numerous advantages over the isoelectric precipitation and salt precipitation. Factor IX may be purified from transgenic milk with an elevated purity by chromatographic methods that do not use immunoaffinity and are finally scalable in industrial production, which provides new perspectives for treating hemophilia B by preparing new oral formulations.

Determinación del anticoagulante lúpico: experiencia de 4 años / Determination of the lupus anticoagulant: a 4-year experience

Se realizó un estudio retrospectivo de los resultados de la determinación del anticoagulante lúpico (AL) realizadas en el período comprendido entre julio del 2000 y julio del 2004 en el laboratorio de hemostasis del Instituto de Hematología e Inmunología. En este período se le realizó la determinación del AL a 380 muestras, el 86 por ciento de las cuales pertenecían a pacientes del sexo femenino, la positividad global fue del 7,3 por ciento, el tiempo de veneno de víbora de Russell diluido fue la prueba que detectó más casos positivos (50 por ciento), pero se evidenció la necesidad de realizar más de una prueba para detectar todos los casos positivos. La prevalencia del AL se comportó de la siguiente forma: en el lupus eritematoso sistémico fue del 17,8 por ciento, en la anemia hemolítica autoinmune del 21 por ciento, en la púrpura trombocitopénica idiopática del 7,6 por ciento, en un grupo de misceláneas que incluyó principalmente artralgias, vasculitis, síndrome de Evan- Fischer, tiempo parcial de tromboplastina prolongado, sangramientos e infecciones a repetición fue del 3,5 por ciento, en pacientes con trombosis fue del 7,6 por ciento y en pacientes con abortos a repetición y/o pérdidas fetales del 4,6 por ciento; resulta de gran importancia su determinación en enfermedades autoinmunes, ya que el 39 por ciento de los casos positivos pertenecían a este grupo, aunque su positividad fue baja en el grupo de mujeres con abortos y/o pérdidas fetales a repetición y en pacientes con trombosis

Anticoagulante lúpico en enfermedades autoinmunes / Lupus anticoagulant in autoimmune diseases

El tromboembolismo venoso es una complicación reconocida en diferentes enfermedades autoinmunes. Se ha establecido que la detección del anticoagulante lúpico (AL) y posiblemente los anticuerpos anticardiolipina (AAC) tipo Ig G en título alto y medio, ayuden a identificar pacientes con riesgo de trombosis. Estudiamos el AL en 81 pacientes con enfermedades autoinmunes: 25 pacientes con lupus eritematoso sistémico (LES), 28 pacientes con púrpura trombocitopénica idiopática (PTI), 15 con anemia hemolítica autoinmune (AHAI) y 13 que se incluyeron en el grupo de otras enfermedades, que comprendían vasculitis cutánea de pequeños vasos, enfermedad mixta del tejido conectivo, artritis reumatoidea y esclerodermia. El AL se encontró en el 19,7 por ciento del total de los estudiados: 16 por ciento en pacientes con LES, 21,4 por ciento en pacientes con PTI y 40 por ciento en la AHAI. En el grupo de otras enfermedades no se halló ningún paciente con el AL positivo. El 56,3 por ciento de los pacientes con AL positivo presentaron alguna manifestación atribuible al síndrome antifosfolípido (SAF)
