RESUMO

Lymphomas are a large, heterogeneous group of neoplasms with well-defined characteristics, and this heterogeneity highlights the importance of epidemiological data. Knowledge of local epidemiology is essential to optimise resources, design clinical trials, and identify minority entities. Given there are few published epidemiological data on lymphoma in Spain, the Spanish Lymphoma and Autologous Bone Marrow Transplant Group created the RELINF project. The aim of this project is to determine the frequencies and distribution of lymphoid neoplasms in Spain and to analyse survival. We developed an online platform for the prospective collection of data on newly diagnosed cases of lymphoma in Spain between January 2014 and July 2018; 11,400 patients were registered. Diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL) were the most frequent lymphomas in our series. Marginal B cell lymphoma frequency was higher than that reported in other studies, representing more than 11% of mature B cell lymphomas. Peripheral T cell lymphoma not otherwise specified (PTCL-NOS) was the most common subtype of T cell lymphoma, and NK/T cell lymphomas were more frequent than expected (5.4% of total). Hodgkin's lymphoma accounted for 12% of lymphoproliferative syndromes. Overall survival was greater than 90% at 2 years for indolent B cell lymphomas, and approximately 60% for DLBCL, somewhat lower than that previously reported. Survival was poor for PTCL-NOS and angioimmunoblastic T cell lymphoma, as expected; however, it was somewhat better than that in other studies for anaplastic large cell anaplastic lymphoma kinase lymphomas. This is the first prospective registry to report the frequencies, distribution, and survival of lymphomas in Spain. The frequencies and survival data we report here are globally consistent with that reported in other Western countries. These updated frequencies and survival statistics are necessary for developing appropriate management strategies for neoplasias in the Spanish population.

RESUMO

BACKGROUND: Stillbirth and neonatal death are one of the most stressful life events, with negative outcomes for parents. Society does not recognize this type of loss, and parental grieving is particularly complicated and intense. PURPOSE: The aim of this study was to describe and understand the experiences of parents in relation to professional and social support following stillbirth and neonatal death. METHODS: This was a qualitative study based on Gadamer's hermeneutic phenomenology. Twenty-one semistructured interviews were carried out. Inductive analysis was used to find themes based on the data. RESULTS: Twenty-one parents (13 mothers and 8 fathers) from 6 families participated in the study. The analysis identified 2 main themes: (1) "professional care in dealing with parents' grief," with the subthemes "important aspects of professional care," "continuing of pathways of care"; and (2) "effects of social support in parental grief," including the subthemes "the silence that surrounds grieving parents," "family and other children: a key element," and "perinatal loss support groups: a reciprocal help." IMPLICATIONS FOR PRACTICE: Counseling and support according to parents' requirements by an interdisciplinary team of professionals educated in perinatal loss and ethical family-centered care is needed. A social support system for families is necessary to avoid negative emotional consequences. IMPLICATIONS FOR RESEARCH: Further research is needed to analyze midwives' and nurses' experience as facilitators to improve parental grief and the difficulties experienced by the family, other children, and friends of parents with perinatal loss in providing support.

RESUMO

BACKGROUND: Perinatal grief is a process that affects families in biological, psychological, social and spiritual terms. It is estimated that every year there are 2.7 million perinatal deaths worldwide and 4.43 deaths for every 1000 births in Spain. The aim of this study is to describe and understand the experiences and perceptions of parents who have suffered a perinatal death. METHODS: A qualitative study based on Gadamer's hermeneutic phenomenology. The study was conducted in two hospitals in the South of Spain. Thirteen mothers and eight fathers who had suffered a perinatal death in the 5 years prior to the study participated in this study. In-depth interviews were carried out for data collection. Inductive analysis was used to find themes based on the data. RESULTS: Eight sub-themes emerged, and they were grouped into three main themes: 'Perceiving the threat and anticipating the baby's death: "Something is going wrong in my pregnancy"'; 'Emotional outpouring: the shock of losing a baby and the pain of giving birth to a stillborn baby'; "We have had a baby": The need to give an identity to the baby and legitimise grief'. CONCLUSION: The grief suffered after a perinatal death begins with the anticipation of the death, which relates to the mother's medical history, symptoms and premonitions. The confirmation of the death leads to emotional shock, characterised by pain and suffering. The chance to take part in mourning rituals and give the baby the identity of a deceased baby may help in the grieving and bereavement process. Having empathy for the parents and notifying them of the death straightaway can help ease the pain. Midwives can help in the grieving process by facilitating the farewell rituals, accompanying the family, helping in honouring the memory of the baby, and supporting parents in giving the deceased infant an identity that makes them a family member.

RESUMO

BACKGROUND: Most people who make the transition to renal replacement therapy (RRT) are treated with a fixed dose thrice-weekly hemodialysis réegimen, without considering their residual kidney function (RKF). Recent papers inform us that incremental hemodialysis is associated with preservation of RKF, whenever compared with conventional hemodialysis. The objective of the present controlled randomized trial (RCT) is to determine if start HD with one sessions per week (1-Wk/HD), it is associated with better patient survival and other safety parameters. METHODS/DESIGN: IHDIP is a multicenter RCT experimental open trial. It is randomized in a 1:1 ratio and controlled through usual clinical practice, with a low intervention level and non-commercial. It includes 152 incident patients older than 18 years, with a RRF of ≥4 ml/min/1.73 m2, measured by renal clearance of urea (KrU). The intervention group includes 76 patients who will start with incremental HD (1-Wk/HD). The control group includes 76 patients who will start with thrice-weekly hemodialysis régimen. The primary outcome is assessing the survival rate, while the secondary outcomes are the morbidity rate, the clinical parameters, the quality of life and the efficiency. DISCUSSION: This study will enable to know the number of sessions a patient should receive when starting HD, depending on his RRF. The potentially important clinical and financial implications of incremental hemodialysis warrant this RCT. TRIAL REGISTRATION: U.S. National Institutes of Health, ClinicalTrials.gov .

RESUMO

AIMS: To explore and understand the experiences of terminally ill patients and their relatives regarding dignity during end-of-life care in the emergency department. BACKGROUND: The respect given to the concept of dignity is significantly modifying the clinical relationship and the care framework involving the end-of-life patient in palliative care units, critical care units, hospices and their own homes. This situation is applicable to in-hospital emergency departments, where there is a lack of research which takes the experiences of end-of-life patients and their relatives into account. DESIGN: A phenomenological qualitative study. METHODS: The protocol was approved in December 2016 and will be carried out from December 2016-December 2020. The Gadamer's philosophical underpinnings will be used in the design and development of the study. The data collection will include participant observation techniques in the emergency department, in-depth interviews with terminally ill patients and focus groups with their relatives. For the data analysis, the field notes and verbatim transcriptions will be read and codified using ATLAS.ti software to search for emerging themes. DISCUSSION: Emerging themes that contribute to comprehending the phenomenon of dignity in end-of-life care in the emergency department are expected to be found. This study's results could have important implications in the implementation of new interventions in emergency departments. These interventions would be focused on improving: the social acceptance of death, environmental conditions, promotion of autonomy and accompaniment and assumption (takeover) of dignified actions and attitudes (respect for human rights).

RESUMO

BACKGROUND: A growing number of studies have identified an association between exposure to inorganic arsenic and hypertension. However, results have not been consistent across studies. Additional studies are warranted, given the global prevalence of both arsenic exposure and morbidity attributable to hypertension. METHODS: We analyzed data collected from October 2007-December 2010 for a population-based cancer case-control study in northern Chile. Data included lifetime individual arsenic exposure estimates and information on potential confounders for a total of 1266 subjects. Those self-reporting either a physician diagnosis of hypertension or use of an anti-hypertensive medication were classified as having hypertension (n=612). The association between hypertension and drinking water arsenic exposure was analyzed using logistic regression models. RESULTS: Compared to those in the lowest category for lifetime highest 5-year average arsenic exposure (<60µg/L), those in the middle (60-623µg/L) and upper (>623µg/L) exposure categories had adjusted hypertension ORs of 1.49 (95% CI: 1.09, 2.05) and 1.65 (95% CI: 1.18, 2.32), respectively. Similar results were observed in analyses of lifetime cumulative exposures and analyses restricted to exposures from the distant past. CONCLUSIONS: We identified evidence of increased odds of hypertension with exposure to arsenic in drinking water among study participants. Our findings add to the growing body of research supporting this association, which could have important public health implications.

RESUMO

Tuberous sclerosis complex (TSC) is a multisystem autosomal dominant disease caused by mutations in the tumor suppressor genes TSC1 or TSC2. OBJECTIVE: To characterize clinically and genetically patients diagnosed with TSC. PATIENTS AND METHOD: Descriptive study of clinical records of 42 patients from a pediatric neuropsychiatry department diagnosed with TSC and genetic study in 21 of them. The exon 15 of TSC1 gene and exons 33, 36 and 37 of TSC2 gene were amplified by polymerase chain reaction and sequenced. The relationship between the mutations found with the severity and clinical course were analyzed. RESULTS: In 61.9% of the patients the symptoms began before 6 months of age. The initial most frequent manifestations of TSC were new onset of seizures (73.8%) and the detection of cardiac rhabdomyomas (16.6%). During the evolution of the disease all patients had neurological involvement; 92.9% had epilepsy. All patients presented hypomelanotic spots, 47.6% facial angiofibromas, 23.8% Shagreen patch, 47.6 heart rhabdomyomas and 35.7% retinal hamartomas. In the genetic study of 21 patients two heterozygous pathogenic mutations in TSC1 and one in TSC2 genes were identified. The latter had a more severe clinical phenotype. CONCLUSIONS: Neurological and dermatological manifestations were the most frequent ones in patients with TSC. Two pathogenic mutations in TSC1 and one in TSC2 genes were identified. The patient with TSC2 mutation manifested a more severe clinical phenotype.

RESUMO

The incidence, epidemiology, and risk factors of bloodstream infection (BSI) and their impact on transplant outcomes after umbilical cord blood transplantation (UCBT) are not well defined. Between May 1997 and December 2012, 202 isolates in 189 episodes of BSI were registered in 134 of 241 patients who underwent single-unit myeloablative UCBT. Cumulative incidence (CI) of developing at least 1 episode of BSI was 21%, 29%, 34%, 42%, and 52% at days +7, +14, +30, +100, and +365, respectively. The median time of onset for the first BSI episode was day +10 (range, day -7 to +1217). Early BSI before day 7 was associated with increased nonrelapse mortality (relative risk [RR], 1.5; 95% confidence interval [CI], 1.1 to 2.3; P = .04), whereas BSI before day 14 was an independent adverse risk factor for neutrophil recovery (RR, .6; 95% CI, .5 to .9; P = .002). A higher CD8(+) cell dose of the graft was the only variable independently associated with reduced risk of BSI (RR, .1; 95% CI, .02 to .7; P = .02). The gram-negative rod (GNR) to gram-positive bacteria ratio was .9 before day +30 and 1.6 thereafter (P = .03). Escherichia coli (31%) and Pseudomonas sp. (28%) were the most frequently isolated among GNR. The overall crude mortality rate was 12% at day 7 and was higher for GNR (18%) compared with gram-positive bacteria (7%) (P = .03). These findings emphasize the importance of preventing bacterial infections during conditioning and the very early post-UCBT period.

RESUMO

This retrospective study analyzed the impact of directional donor-recipient human leukocyte antigen (HLA) disparity using allele-level typing at HLA-A, -B, -C, and -DRB1 in 79 adults with acute myeloid leukemia (AML) who received single-unit umbilical cord blood (UCB) transplant at a single institution. With extended high-resolution HLA typing, the donor-recipient compatibility ranged from 2/8 to 8/8. HLA disparity showed no negative impact on nonrelapse mortality (NRM), graft-versus-host (GVH) disease or engraftment. Considering disparities in the GVH direction, the 5-year cumulative incidence of relapse was 44% and 22% for patients receiving an UCB unit matched ≥ 6/8 and < 6/8, respectively (P = .04). In multivariable analysis, a higher HLA disparity in the GVH direction using extended high-resolution typing (Risk ratio [RR] 2.8; 95% confidence interval [CI], 1.5 to 5.1; P = .0009) and first complete remission at time of transplantation (RR 2.1; 95% CI, 1.2 to 3.8; P = .01) were the only variables significantly associated with an improved disease-free survival. In conclusion, we found that in adults with AML undergoing single-unit UCBT, an increased number of HLA disparities at allele-level typing improved disease-free survival by decreasing the relapse rate without a negative effect on NRM.

RESUMO

Total nucleated (TNCs) and CD34(+) cells are considered major determinants of outcome after umbilical cord blood (UCB) transplantation but the effect of other cell subtypes present in the graft is unknown. This single-center cohort study included patients with hematological malignancies who received UCB transplantation after a myeloablative conditioning regimen. UCB units were primarily selected according to cell content, both TNCs and CD34(+) cells, and also according to the degree of HLA matching. Counts of several cell subtypes of the infused UCB unit, together with HLA disparities and other patient- and transplantation-related characteristics, were analyzed by multivariable methodology for their association with myeloid and platelet engraftment, graft-versus-host disease, nonrelapse mortality (NRM), disease-free survival (DFS), and overall survival (OS). Two hundred patients (median age, 32 years) were included in the study. In multivariable analyses, a greater number of CD8(+) cells was significantly associated with better results for myeloid (P = .001) and platelet (P = .008) engraftment, NRM (P = .02), DFS (P = .007), and OS (P = .01). CD34(+) cell content was predictive of myeloid engraftment (P < .001). This study suggests that the outcome after UCB transplantation in adults with hematological malignancies could be better when UCB grafts had a greater CD8(+) cell content.

RESUMO

AIM: To compare the effectiveness of alternating pressure air mattresses vs. overlays to prevent pressure ulcers in mechanically ventilated patients in intensive care units. BACKGROUND: Pressure ulcers prevention is an important issue in the nursing of critically ill patients. It is not clear whether alternating pressure air mattresses are more effective than overlays to prevent pressure ulcers. DESIGN: Prospective quasi-experimental study. METHODS: A prospective quasi-experimental study was conducted among patients in the medical-surgery intensive care unit of a university hospital on mechanical ventilation ≥24 hours during two time periods (2001 and 2006). Overlays were used in 2001 and mattresses in 2006. Primary outcome was the incidence of pressure ulcers grade ≥II (according to the European Pressure Ulcer Advisory Panel) during intensive care unit stay. RESULTS: The study included 221 patients (116 in 2001 and 105 in 2006). Baseline characteristics were similar between groups except for a higher Acute Physiology and Chronic Health Evaluation III score, total and first-day respiratory Sequential Organ Failure Assessment Score on day 1 in overlay group. There was significantly lower incidence density in the mattress vs. overlay group (12·41 cases/1000 days vs. 18·67 cases/1000 days of stay). The multivariate analyses showed the use of the mattress to be a protective factor against pressure ulcer onset. CONCLUSION: This quasi-experiment study that alternative pressure air mattresses were more effective than alternating pressure air overlays in preventing pressure ulcers in mechanically ventilated critical care patients.

RESUMO

The objective was to determine the plasma concentrations of ionized Ca (iCa) and Mg (iMg) and to establish the prevalence of subclinical hypocalcemia (SCHC) and hypomagnesemia (SCHM) in dairy cows at calving (within 6 hours of parturition) and at 7 days postpartum (pp) in Chilean grazing herds with spring parturitions. Plasma iCa and iMg were assessed using a clinical analyzer. A total of 113 and 175 cows in 18 herds selected at random were sampled at calving and at 7 days pp, respectively. From these 18 herds, 11 herds provided reliable records of lactation number and 8 cows per herd were scored for body condition and sampled at calving and then at 7 days pp. Ionized Ca concentrations for the 18 herds were 0.99 ± 0.16 mmol/L (calving) and 1.01 ± 0.13 mmol/L [7 d pp (P > 0.05)]. Ionized Mg concentrations were 0.58 ± 0.12 mmol/L and 0.51 ± 0.09 mmol/L (P ≤ 0.05). For the 11 herds, iCa concentrations at calving were 1.06 mmol/L (lactation 1), 1.02 mmol/L (lactation 2) and 0.89 mmol/L (lactation ≥ 3), while iMg concentrations were 0.63 mmol/L, 0.60 mmol/L, and 0.61 mmol/L, respectively. Herd prevalence for SCHC (iCa < 1.0 mmol/L) at calving was 64.8%. Prevalence by parity was 40%, 54.5% and 86.7% for lactations 1, 2 and ≥ 3, respectively. Herd prevalence of SCHC on day 7 pp was 30.1%. For SCHM (iMg < 0.52 mmol/L) prevalence was 21.6% and 48.9% at calving and at 7 days pp, respectively.

RESUMO

Introduction: Objective: dietary advice provided through a nutritional intervention program (NIP) is recommended by renal clinic guidelines to prevent or treat malnutrition, that could improve quality of life (QoL) and survival in hemodialysis (HD) patients. This study set out to evaluate the effect of a personalized NIP on the nutritional status and its impact on QoL and mortality in dialyzed patients. Material and methods: this was a 12-month intervention study with regular follow-up in which nutritional parameters were measured at baseline and after 6 and 12 months. QoL was assessed by the Kidney Disease Quality of Life version 1.2 (KDQOL-SF) at baseline and at the end of the study. All dialyzed patients received individualized consultations with a trained dietitian. The content of the nutritional education program included a personalized meal plan and educational materials addressing nutrition to manage fluids, electrolytes, and vitamin D. Results: a total of 75 patients were included. After the NIP, visceral proteins, phosphorous, potassium and vitamin D levels had improved significantly (p < 0.001). The percentage of well-nourished patients increased by 30 % (p < 0.001). At the end of the study, the well-nourished patients had significantly improved scores on the general summary areas of the KDQOL-SF, reduced worry concerning fluid and dietary restrictions (p < 0.001), and the survival rate was 12 months longer (p < 0.01). Conclusion: the results of this study suggest that personalized NIP contributed to improved nutritional status, QoL and survival in HD patients.


Introducción: Objetivo: el asesoramiento dietético proporcionado a través de un programa de intervención nutricional (PIN) es recomendado por las guías clínicas renales para prevenir o tratar la desnutrición, puediendo mejorar la calidad de vida (CV) y la supervivencia en pacientes en hemodiálisis (HD). El objetivo de este estudio fue evaluar el efecto de un PNI personalizado sobre el estado nutricional y su impacto en la calidad de vida y la mortalidad en pacientes dializados. Material y métodos: estudio de intervención de 12 meses de duración, con seguimiento periódico de los pacientes en el que se midieron los parámetros nutricionales al inicio, a los 6 y 12 meses. La CV fue evaluada por el cuestionario Kidney Disease Quality of Life versión 1.2 (KDQOL-SF) al inicio y al final del estudio. Todos los pacientes dializados recibieron consultas individualizadas con un dietista. El contenido del programa de educación nutricional incluyó un plan de alimentación personalizado y materiales educativos sobre nutrición para el manejo de fluidos, electrolitos y vitamina D. Resultados: se incluyeron un total de 75 pacientes. Después del PIN, los niveles de proteínas viscerales, fósforo, potasio y vitamina D habían mejorado significativamente (p < 0,001). El porcentaje de pacientes bien nutridos aumentó un 30 % (p < 0,001). Al final del estudio, los pacientes bien nutridos mejoraron significativamente las puntuaciones en las áreas de resumen general del KDQOL-SF, redujeron la preocupación por las restricciones dietéticas y de líquidos (p < 0,001) y la tasa de supervivencia fue de 12 meses superior (p < 0,01). Conclusión: los resultados de este estudio sugieren que el PIN personalizado contribuyó a mejorar el estado nutricional, la calidad de vida y la supervivencia en pacientes en HD.

RESUMO

We investigated the associations of social and built environment and demographic features of urban areas with self-rated health among adults living in four Latin American countries. We estimated multilevel models with harmonized data from 69,840 adults, nested in 262 sub-cities and 112 cities, obtained from the Salud Urbana en América Latina project. Poor self-rated health was inversely associated with services provision score at the sub-city-level and with social environment index at the city-level. We did not identify associations of built environment and demographic features with self-rated health. Approaches and policies to improve health in Latin American should be urban context-sensitive.

RESUMO

Inflammatory bowel disease is accompanied by extraintestinal manifestations in a high percentage of patients. Cutaneous lesions are the second most prevalent of these manifestations, and within these, metastatic Crohn's disease is one of the least common, being the least frequent specific cutaneous manifestation of Crohn's disease. This entity includes cutaneous and subcutaneous lesions with a non-caseating granulomatous appearance on histological analysis identical to that of Crohn's disease. These lesions are not found adjacent to the digestive tract. Due to the low prevalence of these manifestations, conclusive trials on the treatment of choice have not been performed and there is no well-defined therapeutic strategy. Distinct therapies with varying results have been reported. We report the case of a female patient with longstanding and complex Crohn's disease who developed metastatic cutaneous manifestations while receiving adalimumab. The cutaneous manifestations responded well to dose intensification of this drug. A review of the literature is provided.

RESUMO

INTRODUCTION: Alternating hemiplegia of childhood (AHC), is a rare disease characterized by episodes of hemi/quadriplegia, dystonic postures, abnormal eye movements, and movement disorders. ATP1A3 gene mu tations are the most frequently associated with AHC. OBJECTIVE: To present a clinical case of AHC, where genetic study and the observation of home videos were of great diagnostic utility. CLINICAL CASE: Female patient who at 3 months of age presented with several episodes of dystonic postures, clonic movements of extremities, cephalic version, and lateral gaze deviation lasting several minutes. Epilepsy was diagnosed and levetiracetam was administrated, without improvement. EEG and brain MRI were performed, with normal results. Therefore, epilepsy was ruled out and transient dystonia of infancy was suspected, however, the events became more frequent, longer in duration, and charac teristically subsided during sleep. Family members provided home videos that clarified the events. At 6 months of age, the patient presented with alternating hemiparesis. Dystonia genetic panel showed a pathogenic variant of the ATP1A3 gene, confirming the diagnosis. Flunarizine treatment was ini tiated with a good clinical response at 12 months of follow-up. CONCLUSIONS: The diagnosis of AHC is complex and is frequently confused with epilepsy, so it is important to correctly perform the diffe rential diagnosis, including anamnesis, tests such as EEG, and careful observation of clinical events that, with the current access to audiovisual technology, becomes more accurate. The genetic analysis is a great diagnostic tool that, when performed in time, avoids other unnecessary tests and therapies.

RESUMO

Malnutrition is frequent in hemodialysis (HD) patients. Nutritional deficiencies may negatively impact quality of life (QOL). This study examines the utility of the Malnutrition-Inflammation Score (MIS) in detecting nutritional risk (NR) and assesses the correlation between nutritional status and QOL in dialysis patients upon starting a nutritional intervention program (NIP). One hundred and twenty patients were included in this cross-sectional study. The MIS was used to detect NR and the Kidney Disease Quality of Life (KDQOL-SF) instrument version 1.2 was used to assess QOL. 62% of patients were found to be at NR (MIS > 5). Nutritional status was significantly correlated with all generic QOL sub-scales. On a multiple linear regression analysis, malnutrition showed the highest level of explanation in the Kidney Disease Summary Component which explained 28.9% of the variance; the Physical Component Summary which explained 33% of the variance; and the Mental Component Summary which explained 21.5% of the variance. Malnutrition was found to be the most significant predictor of impaired scores on the KDQOL-SF. The use of MIS to identify patients at NR and a nutritional assessment to detect malnutrition in its early stages are important given the effects a NIP can have on improving QOL in HD patients.

RESUMO

This study aims to assess the accuracy of temporary employment as indicator or proxy measure of precarious employment. Using sensitivity and specificity analysis, we compared type of contract (temporary versus permanent) with the Chilean version of the multidimensional Employment Precariousness Scale. Temporary employment exhibited very low sensitivity (<30%) (specificity >90%), resulting in roughly 38% of false negative results. Different EPRES-Ch cut-off scores produced similar results. The main implication of these findings is that the public health relevance of precarious employment is being underestimated both in terms of prevalence and of its association with health, making it critical that valid multidimensional measures of precarious employment be implemented.
