Recovery of polyclonal immunoglobulins during treatment in patients ineligible for autologous stem-cell transplantation is a prognostic marker of longer progression-free survival and overall survival.

Immunoparesis is the suppression of normal polyclonal immunoglobulins and is present in most patients with newly diagnosed multiple myeloma (MM). The association of immunoparesis at diagnosis, and particularly its recovery along with treatment, with survival in patients ineligible for autologous stem-cell transplantation (ASCT) has not been well established. This retrospective study evaluated the impact of immunoparesis in 431 patients diagnosed with MM, ineligible for ASCT, with a median overall survival of 36 months [95% confidence interval (CI): 31-40]. Immunoparesis was present in 81.2% of patients at diagnosis and was associated with a trend to a worse overall response rate (ORR: 84.8% vs. 74.9%; OR 1.88 (95% CI: 0.97-3.63), shorter progression-free survival (PFS) [22.0 vs. 18.2 months; hazard ratio (HR) 0.775; 95%CI: 0.590-1.018; p = 0.066], and overall survival (OS) (45.9 vs. 34.2 months; HR 0.746; 95% CI: 0.551-1.010; p = 0.057). Twenty-four per cent of patients who had immunoparesis at diagnosis recovered polyclonal immunoglobulins in the follow-up period. Interestingly, these patients had a better ORR (96.3% vs. 68.2%; OR 12.29 (95% CI: 3.77-40.06), PFS (HR 0.703; 95CI%: 0.526-0.941; p = 0.018) and OS (HR 0.678; 95 CI%: 0.503-0.913; p = 0.011) than patients who did not recover it. In summary, restoring a healthy immune system along with first-line treatment in patients with MM, not receiving ASCT, is associated with better outcomes.

6q deletion in Waldenström macroglobulinaemia negatively affects time to transformation and survival.

Deletion of the long arm of chromosome 6 (del6q) is the most frequent cytogenetic abnormality in Waldenström macroglobulinaemia (WM), occurring in approximately 50% of patients. Its effect on patient outcome has not been completely established. We used fluorescence in situ hybridisation to analyse the prevalence of del6q in selected CD19+ bone marrow cells of 225 patients with newly diagnosed immunoglobulin M (IgM) monoclonal gammopathies. Del6q was identified in one of 27 (4%) cases of IgM-monoclonal gammopathy of undetermined significance, nine of 105 (9%) of asymptomatic WM (aWM), and 28/93 (30%) of symptomatic WM (sWM), and was associated with adverse prognostic features and higher International Prognostic Scoring System for WM (IPSSWM) score. Asymptomatic patients with del6q ultimately required therapy more often and had a shorter time to transformation (TT) to symptomatic disease (median TT, 30 months vs. 199 months, respectively, P < 0·001). When treatment was required, 6q-deleted patients had shorter progression-free survival (median 20 vs. 47 months, P < 0·001). The presence of del6q translated into shorter overall survival (OS), irrespective of the initial diagnosis, with a median OS of 90 compared with 131 months in non-del6q patients (P = 0·01). In summary, our study shows that del6q in IgM gammopathy is associated with symptomatic disease, need for treatment and poorer clinical outcomes.

Long-term outcome comparing histological grades of follicular lymphoma patients treated with immunochemotherapy as first-line therapy: A retrospective analysis from two institutions.

OBJECTIVES: To clarify the impact of histological grades in follicular lymphoma. METHODS: We retrospectively analysed 250 patients diagnosed with FL treated with chemoimmunotherapy: 188 patients were grades 1-2 and 62 grade 3A. RESULTS: In our series, grade 3A FL patients were older, higher proportion of localised disease and lower bone marrow infiltration at diagnosis comparing grades 1-2 FL patients. Estimated six-year progression-free survival and time to progression showed no differences between both groups [grade 3A: 56% (95%CI: 39%-73%) and 51% (95%CI: 41%-61%) vs grades 1-2:55% (95%CI: 46%-63%) and 57% (95%CI: 49%-65%), P = .782 and P = .521, respectively]. Estimated six-year overall survival was lower, 76% (95%CI: 64%-88%) for the grade 3A group than grades 1-2 83% (95%CI: 77%-89%); P = .044. In addition to that, cumulative incidence curves of death not related to lymphoma at 10 years between groups were as follows: [0.26 (95%CI: 0.25-0.27) and 0.05 (95%CI: 0.04-0.06) for G3AFL and G1-2FL, respectively], P = .010. Grade 3A FL showed in PFS curve no relapses after 6 years. These results were absolutely reproduced in 199 patients receiving R-CHOP regimen as induction. CONCLUSIONS: Our results indicate similar long-term outcomes in terms of progression-free survival and time to progression in grades 1-2 and 3A. No relapses were observed in G3AFL group after 6 years.

Clinicopathologic features and prognostic significance of CD30 expression in de novo diffuse large B-cell lymphoma (DLBCL): results in a homogeneous series from a single institution.

Introduction: The present study evaluates CD30 expression by immunohistochemistry (IHQ) in 216 patients with de novo DLBCL.Methods: CD30 expression was assessed retrospectively in all cases by IHQ. More than >0% and >20% of CD30 expression in the malignant cells were used as a cut-off for positivity. Survival was analysed in 176 patients treated with R-CHOP/R-CHOP-like regimens.Results: CD30 expression >0% was found in 66 (31%) patients, and >20% in 41 (19%). Younger patients <60 years (p = 0.03), good performance status (p = 0.04), and non-GCB subtype (p = 0.004) correlated with CD30 expression. No significant differences were found in overall survival and progression-free survival (PFS), although there was a trend towards better PFS in CD30-positive patients (p = 0.07). Among 7 patients with Epstein-Barr virus (EBV)-positive-DLBCL, CD30 was expressed in 71%, and 2-year PFS significantly inferior compared with CD30-positive EBV-negative-DLBCL patients (p = 0.01).Conclusion: CD30 is expressed in 30% of DLBCL patients, in whom targeted therapy with an anti-CD30 monoclonal antibody could be explored. CD30 is expressed more frequently younger patients, with better performance status and in the non-GCB subtype and its expression trends towards a better PFS. No significant differences regarding characteristics at diagnosis or prognosis were found between groups with different cut-off for positivity.

Recovery of polyclonal immunoglobulins one year after autologous stem cell transplantation as a long-term predictor marker of progression and survival in multiple myeloma.

Immunoparesis or suppression of polyclonal immunoglobulins is a very common condition in newly diagnosed myeloma patients. However, the recovery of polyclonal immunoglobulins in the setting of immune reconstitution after autologous stem cell transplantation and its effect on outcome has not yet been explored. We conducted this study in a cohort of 295 patients who had undergone autologous transplantation. In order to explore the potential role of immunoglubulin recovery as a dynamic predictor of progression or survival after transplantation, conditional probabilities of progression-free survival and overall survival were estimated according to immunoglobulin recovery at different time points using a landmark approach. One year after transplant, when B-cell reconstitution is expected to be completed, among 169 patients alive and progression free, 88 patients (52%) showed immunoglobulin recovery and 81 (48%) did not. Interestingly, the group with immunoglobulin recovery had a significantly longer median progression-free survival than the group with persistent immunoparesis (median 60.4 vs. 27.9 months, respectively; Hazard Ratio: 0.45, 95%Confidence Interval: 0.31-0.66; P<0.001), and improved overall survival (11.3 vs. 7.3 years; Hazard Ratio: 0.45, 95%Confidence Interval: 0.27-0.74; P=0.002). Furthermore, the percentage of normal plasma cells detected by flow cytometry in the bone marrow assessed at day 100 after transplantation was associated with the immunoglobulin recovery at that time and may predict immunoglobulin recovery in the subsequent months: nine months and one year. In conclusion, the recovery of polyclonal immunoglobulins one year after autologous transplantation in myeloma patients is an independent long-term predictor marker for progression and survival.

In situ molecular identification of the influenza A (H1N1) 2009 Neuraminidase in patients with severe and fatal infections during a pandemic in Mexico City.

BACKGROUND: In April 2009, public health surveillance detected an increased number of influenza-like illnesses in Mexico City's hospitals. The etiological agent was subsequently determined to be a spread of a worldwide novel influenza A (H1N1) triple reassortant. The purpose of the present study was to demonstrate that molecular detection of pandemic influenza A (H1N1) 2009 strains is possible in archival material such as paraffin-embedded lung samples. METHODS: In order to detect A (H1N1) virus sequences in archived biological samples, eight paraffin-embedded lung samples from patients who died of pneumonia and respiratory failure were tested for influenza A (H1N1) Neuraminidase (NA) RNA using in situ RT-PCR. RESULTS: We detected NA transcripts in 100% of the previously diagnosed A (H1N1)-positive samples as a cytoplasmic signal. No expression was detected by in situ RT-PCR in two Influenza-like Illness A (H1N1)-negative patients using standard protocols nor in a non-related cervical cell line. In situ relative transcription levels correlated with those obtained when in vitro RT-PCR assays were performed. Partial sequences of the NA gene from A (H1N1)-positive patients were obtained by the in situ RT-PCR-sequencing method. Sequence analysis showed 98% similarity with influenza viruses reported previously in other places. CONCLUSIONS: We have successfully amplified specific influenza A (H1N1) NA sequences using stored clinical material; results suggest that this strategy could be useful when clinical RNA samples are quantity limited, or when poor quality is obtained. Here, we provide a very sensitive method that specifically detects the neuraminidase viral RNA in lung samples from patients who died from pneumonia caused by Influenza A (H1N1) outbreak in Mexico City.

Influence of income on in-hospital mortality in older adults during the first wave of the COVID-19 pandemic: results from the EDEN-33 study. / Influencia de la renta económica en la mortalidad intrahospitalaria de las personas mayores durante la primera ola de la pandemia por COVID-19: resultados del estudio EDEN-33.

OBJECTIVES: To determine whether income was associated with unexpected in-hospital mortality in older patients treated in Spanish public health system hospital emergency departments. MATERIAL AND METHODS: Fifty-one public health system hospital emergency departments in Spain voluntarily participated in the study. Together the hospitals covered 25% of the population aged 65 years or older included in all patient registers during a week in the pre-pandemic period (April 1-7, 2019) and a week during the COVID-19 pandemic (March 30 to April 5, 2020). We estimated a patient's gross income as the amount published for the postal code of the patient's address. We then calculated the standardized gross income (SGI) by dividing the patient's estimated income by the mean for the corresponding territory (Spanish autonomous community). The existence and strength of an association between the SGI and in-hospital mortality was evaluated by means of restricted cubic spline (RCS) curves adjusted for 10 patient characteristics at baseline. Odds ratios (ORs) for each income level were expressed in relation to a reference SGI of 1 (the mean income for the corresponding autonomous community). We compared the COVID-19 and pre-pandemic periods by means of first-order interactions. RESULTS: Of the 35 280 patients attended in the 2 periods, gross income could be ascertained for 21 180 (60%), 15437 in the pre-pandemic period and 5746 during the COVID-19 period. SGIs were slightly higher for patients included before the pandemic (1.006 vs 0.994; P = .012). In-hospital mortality was 5.6% overall and higher during the pandemic (2.8% pre-pandemic vs 13.1% during COVID-19; P .001). The adjusted RCS curves showed that associations between income and mortality differed between the 2 periods (interaction P = .004). Whereas there were no significant income-influenced differences in mortality before the pandemic, mortality increased during the pandemic in the lowest-income population (SGI 0.5 OR, 1.82; 95% CI, 1.32-3.37) and in higher-income populations (SGI 1.5 OR, 1.32; 95% CI, 1.04-1.68, and SGI 2 OR, 1.92; 95% CI, 1.14-3.23). We found no significant differences between patients with COVID-19 and those with other diagnoses (interaction P = .667). CONCLUSION: The gross income of patients attended in Spanish public health system hospital emergency departments, estimated according to a patient's address and postal code, was associated with in-hospital mortality, which was higher for patients with the lowest and 2 higher income levels. The reasons for these associations might be different for each income level and should be investigated in the future.

OBJETIVO: Determinar si el nivel económico durante la primera ola pandémica tuvo una influencia diferente a la esperable en la mortalidad intrahospitalaria de los pacientes mayores atendidos en los servicios de urgencias (SU) de los hospitales públicos españoles. METODO: Cincuenta y un SU públicos españoles que participaron voluntariamente y que dan cobertura al 25% de la población incluyeron todos los registros de pacientes de edad 65 años atendidos durante una semana del periodo preCOVID (1-4-2019 a 7-4-2019) y una semana del periodo COVID (30-3-2020 a 5-4-2020). Se identificó la renta bruta (RB) asignada al código postal de residencia de cada paciente y se calculó la RB normalizada (RBN) dividiendo aquella por la RB media de su comunidad autónoma. La existencia y fuerza de la relación entre RBN y mortalidad intrahospitalaria se determinó mediante curvas spline cúbicas restringidas (SCR) ajustadas por 10 características basales del paciente. Las OR para cada situación económica se expresó en relación con una RBN de 1 (referencia, renta correspondiente a la media de la comunidad autónoma). La comparación entre periodo COVID y no COVID se realizó mediante el estudio de interacción de primer grado. RESULTADOS: De los 35.280 registros de pacientes atendidos en ambos periodos, se disponía de la RB en 21.180 (60%): 15.437 del periodo preCOVID y 5.746 del periodo COVID. La RBN de los pacientes incluidos fue discretamente superior en el periodo preCOVID (1,006 versus 0,994; p = 0,012). La mortalidad intrahospitalaria fue del 5,6%, y fue superior durante el periodo COVID (2,8% versus 13,1%; p 0,001). Las curvas SCR ajustadas mostraron una asociación entre nivel económico y mortalidad diferente entre ambos periodos (p interacción = 0,004): en el periodo preCOVID no hubo diferencias significativas de mortalidad en función de la RBN, mientras que en el periodo COVID la mortalidad se incrementó en rentas bajas (OR = 1,82, IC 95% = 1,32-3,37 para RBN de 0,5) y en rentas altas (OR = 1,32, IC 95% = 1,04-1,68 y OR = 1,92, IC 95% = 1,14-3,23 para RBN de 1,5 y 2, respectivamente), sin diferencias significativas entre pacientes con COVID y con otros diagnósticos (p interacción = 0,667). CONCLUSIONES: Durante la primera ola de la pandemia COVID, la RB asignada al código postal de residencia de los pacientes atendidos en los SU públicos españoles se asoció con la mortalidad intrahospitalaria, que aumentó en pacientes de rentas bajas y altas. Las razones de estas asociaciones pueden ser distintas para cada segmento económico y deben ser investigadas en el fututo.

Sociodemographic characteristics, comorbidity, and baseline functional status of older patients treated in emergency departments during the COVID-19 pandemic and associations with mortality: an analysis based on the EDENCOVID cohort. / Sociodemografía, comorbilidad y situación funcional basal de los pacientes mayores atendidos en urgencias durante la pandemia de COVID y su relación con la mortalidad: análisis a partir de la cohorte EDEN-Covid.

OBJECTIVES: To describe the sociodemographic characteristics, comorbidity, and baseline functional status of patients aged 65 or older who came to hospital emergency departments (EDs) during the first wave of the COVID-19 pandemic, and to compare them with the findings for an earlier period to analyze factors of the index episode that were related to mortality. MATERIAL AND METHODS: We studied data from the EDEN-COVID cohort (Emergency Department and Elder Needs During COVID-19) of patients aged 65 years or older treated in 40 Spanish EDs on 7 consecutive days. Nine sociodemographic variables, 18 comorbidities, and 7 function variables were registered and compared with the findings for the EDEN cohort of patients included with the same criteria and treated a year earlier in the same EDs. In-hospital mortality was calculated in the 2 cohorts and a multivariable logistic regression model was used to explore associated factors. RESULTS: The EDEN-COVID cohort included 6806 patients with a median age of 78 years; 49% were women. The pandemic cohort had a higher proportion of men, patients covered by the national health care system, patients brought from residential facilities, and patients who arrived in an ambulance equipped for advanced life support. Pandemic-cohort patients more often had diabetes mellitus, chronic kidney disease, and dementia; they less often had connective tissue and thromboembolic diseases. The Barthel and Charlson indices were worse in this period, and cognitive decline was more common. Fewer patients had a history of depression or falls. Eight hundred ninety these patients (13.1%) died, 122 of them in the ED (1.8%); these percentages were lower in the earlier EDEN cohort, at 3.1% and 0.5%, respectively. Independent sociodemographic factors associated with higher mortality were transport by ambulance, older age, male sex, and living in a residential facility. Mortalityassociated comorbidities were neoplasms, chronic kidney disease, and heart failure. The only function variable associated with mortality was the inability to walk independently. A history of falls in the past 6 months was a protective factor. CONCLUSION: The sociodemographic characteristics, comorbidity, and functional status of patients aged 65 years or older who were treated in hospital EDs during the pandemic differed in many ways from those usually seen in this older-age population. Mortality was higher than in the prepandemic period. Certain sociodemographic, comorbidity, and function variables were associated with in-hospital mortality.

OBJETIVO: Investigar sociodemografía, comorbilidad y situación funcional de los pacientes de 65 o más años de edad que consultaron a los servicios de urgencias hospitalarios (SUH) durante la primera oleada epidémica de COVID, compararlas con un periodo previo y ver su relación. METODO: Se utilizaron los datos obtenidos de la cohorte EDEN-Covid (Emergency Department and Elder Needs during COVID) en la que participaron 40 SUH españoles que incluyeron todos los pacientes de $ 65 años atendidos durante 7 días consecutivos. Se analizaron 9 características sociodemográficas, 18 comorbilidades y 7 variables de funcionalidad, que se compararon con las de la cohorte EDEN (Emergency Department and Elder Needs), que contiene pacientes con el mismo criterio de inclusión etario reclutados por los mismos SUH un año antes. Se recogió la mortalidad intrahospitalaria y se investigaron los factores asociados mediante regresión logística multivariable. RESULTADOS: La cohorte EDEN-Covid incluyó 6.806 pacientes (mediana edad: 78 años; 49% mujeres). Hubo más varones, con cobertura sanitaria pública, procedentes de residencia y que llegaron con ambulancia medicalizada que durante el periodo prepandemia. Presentaron más frecuentemente diabetes mellitus, enfermedad renal crónica, enfermedad cerebrovascular y demencia y menos conectivopatías y enfermedad tromboembólica, peores índices de Barthel y Charlson, más deterioro cognitivo y menos antecedentes de depresión o caídas previas. Fallecieron durante el episodio 890 pacientes (13,1%), 122 de ellos en urgencias (1,8%), porcentajes superiores al periodo prepandemia (3,1% y 0,5%, respectivamente). Se asociaron de forma independiente a mayor mortalidad durante el periodo COVID la llegada en ambulancia, mayor edad, ser varón y vivir en residencia como variables sociodemográficas, y neoplasia, enfermedad renal crónica e insuficiencia cardiaca como comorbilidades. La única variable funcional asociada a mortalidad fue no deambular respecto a ser autónomo, y la existencia de caídas los 6 meses previos resultó un factor protector. CONCLUSIONES: La sociodemografía, comorbilidad y funcionalidad de los pacientes de 65 o más años que consultaron en los SUH españoles durante la primera ola pandémica difirieron en muchos aspectos de lo habitualmente observado en esta población. La mortalidad fue mayor a la del periodo prepandémico. Algunos aspectos sociodemográficos, de comorbilidad y funcionales se relacionaron con la mortalidad intrahospitalaria.

Effectiveness of a training intervention to improve communication between/awareness of team roles: A randomized clinical trial.

BACKGROUND: Interprofessional teamwork training of nursing undergraduates is essential to improving healthcare. The absence of clear role definitions and poor interprofessional communications have been listed as the main reasons behind abandonment of the profession by recently graduated nurses. PURPOSE: The aim of this parallel randomized clinical trial was to evaluate the impact of Situation-Background-Assessment-Recommendation (SBAR) role-play training on interprofessional teamwork skills (role-related and communication-related) and non-technical skills (patient assessment, patient intervention, patient safety, and critical thinking). METHOD: The intervention group were taught teamwork skills, role and task assignment skills, and use of the SBAR worksheet in a 1-hour role-play training session, while the control group received conventional lecture-based training. Teamwork and non-technical skills were then assessed in high-fidelity simulation scenarios using the KidSIM Team Performance Scale (teamwork skills) and the Clinical Simulation Evaluation Tool (non-technical skills). Cohen's d (d) was used to examine effect size differences. RESULTS: Compared to the control group, the intervention group improved in 4 teamwork items - 'verbalize out loud' (p < 0.001, d = 0.99), 'paraphrase' (p < 0.001, d = 0.77), 'cross-monitoring' (p < 0.001, d = 0.72), and 'role clarity' (p = 0.002, d = 0.66) - and in a single non-technical skill (patient intervention: p = 0.004, d = 0.66), while also reporting greater confidence in performing patient assessments (p = 0.02, d = 0.56). CONCLUSIONS: Role-play and SBAR training for undergraduate nurses improved patient intervention, enhanced information sharing in an interprofessional team, and raised awareness of their own and other team members' roles.

Validation of the NCCN-IPI and the GELTAMO-IPI for diffuse large B-Cell lymphoma treated with R-CHOP in a large cohort of patients from a single institution.

The discriminative power of International Prognostic Index (IPI) in diffuse large B-cell lymphoma (DLBCL) decreased with the addition of rituximab to chemotherapy. The National Comprehensive Cancer Network (NCCN)-IPI and the Grupo Español de Linfomas y Trasplante Autólogo de Médula Ósea (GELTAMO)-IPI were developed to improve the risk prediction for DLBCL patients. We aim to validate the NCCN-IPI and GELTAMO-IPI in a large and homogeneous cohort of 337 DLBCL patients treated with curative intent with R-CHOP/R-CHOP-like immunochemotherapy. The IPI stratifies patients in two independent risk groups and the estimated 5-year overall survival (OS) of the high-risk (HR) group was 43%. NCCN-IPI discriminated four risk groups and GELTAMO-IPI three risk groups of patients. The predicted 5-year OS of the HR group was 38% and 29%, respectively. NCCN-IPI and GELTAMO-IPI are more accurate prognostic indices than IPI in DBLCL patients treated with immunochemotherapy. GELTAMO-IPI demonstrated enhanced discrimination than NCCN-IPI for the higher-risk population.

Implementation of the Spanish Triage System in the emergency departments of public health service hospitals in Andalusia, Spain. / Implantación del Sistema Español de Triaje (SET) en los servicios de urgencias generales de los hospitales públicos de Andalucía (España).

OBJECTIVES: To describe the process of implementing the Spanish Triage System (SET, in its Spanish abbreviation) in nonspecialist hospital emergency departments (EDs) in the public health service. MATERIAL AND METHODS: Multicenter cross-sectional study at 4 time cut-points (6 months before implementation and at the end of 1, 2 and 3 semesters afterwards). The study was carried out in 29 public hospital EDs in Andalusia. We recorded the following data: type of hospital, proportion of cases in which the SET was applied, priority classifications assigned on triage, wait time before triage, and duration of the triage process. We also recorded the following proportions: patients waiting less than 10 minutes for the assigned priority, cases with a triage processing time less than 5 minutes, ED revisits within 72 hours, ED deaths, and patients leaving before discharge. RESULTS: We saw SET use increase progressively over the 3 semesters. The mean wait time decreased, and the proportion of patients waiting less than 10 minutes increased. The mean triage processing time tended to decrease nonsignificantly as the proportion of cases triaged in less than 5 minutes rose. The proportion of patients leaving before discharge increased with time; in overall and by hospital type. The proportion of ED deaths did not change significantly, and revisits within 72 hours increased only in more complex hospitals (P = .019). CONCLUSION: Implementing a structured triage approach like SET is a gradual process. Quality indicators must be followed over time so that the impact of a triage system on ED care processes can be assessed.

OBJETIVO: Describir el proceso de implantación del Sistema Español de Triaje (SET) en los servicios de urgencias de un Sistema Público de Salud. METODO: Estudio multicéntrico, transversal analítico, con 4 cortes temporales (6 meses preimplantación y 3 semestres siguientes) realizado sobre 29 servicios de urgencias de hospitales (SUH) públicos de Andalucía. Se recogió el tipo de hospital, la proporción de uso del SET, de pacientes clasificados según la prioridad, el tiempo de espera para la clasificación (TECLA) y de duración de esta (TICLA); la proporción de pacientes con TECLA menor de 10 min (PTECLA < 10 min) y con TICLA menor de 5 min (Pticla < 5 min); y la proporción de retornos a urgencias en las siguientes 72 horas, de fallecimientos en urgencias y de fugas del SUH. RESULTADOS: Se observó un incremento progresivo del uso del SET durante los sucesivos periodos, una disminución del TECLA y aumento de la PTECLA < 10 min. El TICLA disminuyó no significativamente con aumento de la pTICLA < 5 min. La proporción de fugas se incrementó globalmente y por tipo de hospital a lo largo de los sucesivos períodos. La proporción de fallecimientos en urgencias no se modificó significativamente y la proporción de retornos en las siguientes 72 horas solo se incrementó significativamente en los hospitales de mayor complejidad (p = 0,019). CONCLUSIONES: La implantación de un sistema estructurado de triaje como el SET es un proceso paulatino que requiere la monitorización de indicadores para conocer el impacto que va teniendo sobre la dinámica asistencial del SUH.

Application of a molecular diagnostic algorithm for haemophilia A and B using next-generation sequencing of entire F8, F9 and VWF genes.

Currently, molecular diagnosis of haemophilia A and B (HA and HB) highlights the excess risk-inhibitor development associated with specific mutations, and enables carrier testing of female relatives and prenatal or preimplantation genetic diagnosis. Molecular testing for HA also helps distinguish it from von Willebrand disease (VWD). Next-generation sequencing (NGS) allows simultaneous investigation of several complete genes, even though they may span very extensive regions. This study aimed to evaluate the usefulness of a molecular algorithm employing an NGS approach for sequencing the complete F8, F9 and VWF genes. The proposed algorithm includes the detection of inversions of introns 1 and 22, an NGS custom panel (the entire F8, F9 and VWF genes), and multiplex ligation-dependent probe amplification (MLPA) analysis. A total of 102 samples (97 FVIII- and FIX-deficient patients, and five female carriers) were studied. IVS-22 screening identified 11 out of 20 severe HA patients and one female carrier. IVS-1 analysis did not reveal any alterations. The NGS approach gave positive results in 88 cases, allowing the differential diagnosis of mild/moderate HA and VWD in eight cases. MLPA confirmed one large exon deletion. Only one case did have no pathogenic variants. The proposed algorithm had an overall success rate of 99 %. In conclusion, our evaluation demonstrates that this algorithm can reliably identify pathogenic variants and diagnose patients with HA, HB or VWD.

Myxoma of the renal capsule.

Myxomas are uncommon soft-tissue neoplasms, which are extremely rare in the kidney, with only five cases documented in the intraparenchymal location. However, renal capsular myxoma has not yet been reported. We describe a unique case of a clinically detected renal myxoma arising in the capsule. A 37-year-old man receiving treatment for epididymitis sought medical assistance for infertility. A radiological examination incidentally discovered a right renal tumor. The mass intruded into the perirenal tissue and measured 6 cm in major diameter. The resected kidney contained a well-circumscribed gelatinous capsular tumor. It was composed of sparse, bland, slender, spindle-shaped cells scattered in large amounts of basophilic interstitial mucoid material. The tumor cells showed diffuse immunoreactivity for vimentin. Occasional cells stained for alpha-smooth muscle actin and calponin. Reactivity was negative for S100 protein, epithelial membrane antigen, pancytokeratin, neurofilament protein, and h-caldesmon antibodies. Ultrastructural examination revealed fibroblast-like cells with long thin cytoplasmic processes, prominent rough endoplasmic reticulum, a well-developed Golgi complex, and secretory vesicles. No basal lamina was identified around the tumor cells. The differential diagnosis includes many other benign and malignant soft-tissue lesions exhibiting prominent secondary myxoid features. It is important to consider a renal capsular myxoma when examining lesions at this anatomic site to avoid misdiagnoses and to ensure that the patient receives appropriate treatment and prognostic information.

OBJECTIVE: To describe the process of implementing the Spanish Triage System (SET, in its Spanish abbreviation) in nonspecialist hospital emergency departments (EDs) in the public health service. METHODS: Multicenter cross-sectional study at 4 time cut-points (6 months before implementation and at the end of 1, 2 and 3 semesters afterwards). The study was carried out in 29 public hospital EDs in Andalusia. We recorded the following data: type of hospital, proportion of cases in which the SET was applied, priority classifications assigned on triage, wait time before triage, and duration of the triage process. We also recorded the following proportions: patients waiting less than 10 minutes for the assigned priority, cases with a triage processing time less than 5 minutes, ED revisits within 72 hours, ED deaths, and patients leaving before discharge. RESULTS: We saw SET use increase progressively over the 3 semesters. The mean wait time decreased, and the proportion of patients waiting less than 10 minutes increased. The mean triage processing time tended to decrease nonsignificantly as the proportion of cases triaged in less than 5 minutes rose. The proportion of patients leaving before discharge increased with time; in overall and by hospital type. The proportion of ED deaths did not change significantly, and revisits within 72 hours increased only in more complex hospitals (P = .019). CONCLUSION: Implementing a structured triage approach like SET is a gradual process. Quality indicators must be followed over time so that the impact of a triage system on ED care processes can be assessed

Bone remodelation markers are useful in the management of monoclonal gammopathies.

The evaluation of bone disease in multiple myeloma (MM) by conventional radiology has low reproducibility. In the last decade, several serum and urine biochemical parameters, for evaluation of bone turnover, have become available. The present study was designed to explore the value of six bone remodelation markers. It was studied in a series of 176 newly diagnosed patients with monoclonal gammopathies (107 MM and 69 monoclonal gammopathies of unknown significance (MGUS)). As control groups we used 25 patients with benign osteoporosis (BO) and 32 healthy individuals (HI). The bone markers analyzed included: bone resorption markers (BRM) (total pyridinoline, total deoxypyridinoline, free deoxypyridinoline and C-terminal telopeptide of collagen I) and bone formation markers (BFM) (bone alkaline phosphatase (bAP) and osteocalcin (OC)). Serum or urinary levels of BRM were significantly higher in MM patients than in MGUS patients, BO patients or HI (P < 0.001, respectively). BRM were higher in MM patients with lytic lesions. However, only C-terminal telopeptide discriminated MM patients without bone lesions from MGUS patients. BFM did not show significant differences in the aforementioned comparisons, although a trend toward higher values of OC and lower values of bAP in patients with early bone affectation was observed. Ratios BRM/BFM that contained bAP exhibited differences that were most significant between the MM group and other entities, as well as between the different MM subgroups. In fact, the ratios BRM/bAP provided discrimination between the MM subgroup without lyses and MGUS group (P < 0.01). BRM and BFM, especially the ratios, are useful in the evaluation of bone lesions in patients with monoclonal gammopathies.

Síndrome de la bolsa de orina púrpura: planificación de cuidados / Purple urine syndrome: Care planning

El síndrome de la bolsa de orina púrpura es una entidad poco frecuente, de condición benigna, caracterizada por una reacción química que provoca que la sonda vesical y la bolsa puedan teñirse de color rojo, azul o púrpura. Este fenómeno suele producirse en personas con pluripatología, portadores de sonda vesical y en el contexto de una infección del tracto urinario. Desarrollo del plan de cuidados: Desarrollamos un plan de cuidados mediante la revisión y análisis del caso de una mujer de 86 años, con diagnóstico de síndrome de la bolsa de orina púrpura. Se proponen los diagnósticos enfermeros con la taxonomía NANDA-I, los criterios de resultado con la Nursing Outcomes Classification (NOC) y las intervenciones enfermeras con la Nursing Intervention Classification (NIC). A su vez, se formulan los problemas de colaboración y el desarrollo de las actividades enfermeras que los acompañan. Discusión y conclusión: Es necesario el desarrollo de una planificación de cuidados individualizada y centrada en la persona con síndrome de la bolsa de orina púrpura para conseguir los criterios de resultado planificados y evitar la alarma que implica una decisión terapéutica equivocada y que puede alterar los resultados

The purple urine bag syndrome is an infrequent entity of benign condition but characterized by a chemical that consequence the urinary catheter and bag can get stained red, blue or purple. This phenomenon usually happens in pluripathological patients who carry a urinary catheter due to a urinary tract infection. Development of the care plan: We developed a care plan by reviewing and analyzing the case of an 86-year-old woman with a diagnosis of purple urine bag syndrome. Nursing diagnoses are proposed with the NANDA-I taxonomy, the outcome criteria with the Nursing Outcomes Classification (NOC) and the nursing interventions with the Nursing Intervention Classification (NIC). In turn, we deal with the problems of collaboration and the development of the nursing activities that accompany them. Discussion and conclusion: It is necessary to develop an individualized care planning centered in the person with purple urine bag syndrome to achieve the planned results criteria and avoid the alarm that implies a wrong therapeutics decision that can alter the results

Influence of the structure of mood in the assessment of rheumatoid arthritis through the visual analog scale for pain, HAQ and DAS28.

OBJECTIVE: To analyze the effect of the structure of mood over the following assessment tools for rheumatoid arthritis: visual analog scale (VAS) for pain, HAQ and DAS28. PATIENTS AND METHODS: We studied 86 patients with recent onset rheumatoid arthritis, of which 75.7% were female, with a mean age at disease onset of 55 years. All patients were administered the Spanish version of the PANAS questionnaire that evaluates the components of positive (PA) and negative mood (AN). Patients belonged to the registry of new-onset arthritis in our center so clinical information was available for 282 patients visits. To determine the effect of PA and AN on each of the dependent variables we performed three multivariate linear regression models using generalized linear models through the Stata glm command 10.1. RESULTS: The mean score for PA and AN in our patients was similar to that described for the healthy Spanish population. The high scores on the subscale of AN were associated with worse scores in both the VAS for pain and the HAQ. By contrast, high scores on PA were associated with better outcomes of disease activity measured by DAS28. CONCLUSION: The structure of mood may influence the tools we use for evaluating patients with rheumatoid arthritis, so it might be advisable to include the PANAS questionnaire as part of that assessment.
