Human papillomavirus infection and lung adenocarcinoma: special benefit is observed in patients treated with immune checkpoint inhibitors.

BACKGROUND: Human papilloma virus (HPV) has been associated with the development and modulation of response in a series of neoplasms. In the case of lung adenocarcinoma, its role in etiology and pathogenesis is still controversial. Considering that this infection brings foreign epitopes, it could be of prognostic significance in patients with lung adenocarcinoma treated with immunotherapy. METHODS: In a retrospective cohort study we evaluated the presence of HPV genomic material in lung adenocarcinoma primary lesions with the INNO-LiPA platform. Viral replication was also evaluated by detecting the presence of oncoprotein E6/E7 messenger RNA (mRNA) by quantitative RT-PCR. To confirm possible hypotheses regarding viral oncogenesis, vascular endothelial growth factor (VEGF) and hypoxia-inducible factor 1 (HIF1) were evaluated with stromal fibrosis and immunoscore. RESULTS: A total of 133 patients were included in the analysis, of whom 34 tested positive for HPV, reaching an estimated prevalence of 25.6% [95% confidence interval (CI) 18.2% to 32.9%]. E6/7 mRNA was identified in 28 out of the 34 previously positive cases (82.3%). In immune checkpoint inhibitor (ICI)-treated patients, the median overall survival reached 22.3 months [95% CI 19.4 months- not reached (NR)] for HPV-negative and was not reached in HPV-positive (HPV+) ones (95% CI 27.7-NR; P = 0.008). With regard to progression-free survival, HPV- patients reached a median of 9.2 months (95% CI 7.9-11.2 months) compared to 14.3 months (95% CI 13.8-16.4 months) when HPV was positive (P = 0.001). The overall response rate for HPV+ patients yielded 82.4% compared to 47.1% in negative ones. No differences regarding programmed death-ligand 1, VEGF, HIF1, stromal fibrosis, or immunoscore were identified. CONCLUSIONS: In patients with HPV+ lung adenocarcinoma, a significant benefit in overall response and survival outcomes is observed.

Flu and pertussis vaccination during pregnancy in Geneva during the COVID-19 pandemic: A multicentric, prospective, survey-based study.

OBJECTIVE: To determine pertussis and influenza vaccination coverage during pregnancy among women delivering in all the maternities of Geneva (Switzerland), during the COVID-19 pandemic. METHODS: All women delivering in all the maternity centres of the canton of Geneva from 1st November 2020 to 30th November 2020 (beginning of the flu vaccination season) and from 8th March 2021 to 7th April 2021 (end of the flu vaccination season) had their records checked upon admission to the labour ward regarding pertussis and influenza vaccination during pregnancy. Reasons for non-vaccination were recorded. Univariate and multivariate analyses were done to identify predictors of vaccine uptake. RESULTS: 951 women delivered in Geneva during the two study periods, of which 950 were included in the study. 86.2% were vaccinated against pertussis, with no significant difference between the study periods (87.5% vs 85% at the beginning and end of the flu vaccination season respectively). 49.8% were vaccinated against influenza, with no significant difference between the study periods (48.8% vs 50.7% beginning and end of the flu vaccination season respectively). The influenza vaccine was 5 times more likely not to be proposed (8.9% vs. 1.7%) and 3 times more likely to be refused (26.6% vs. 8%) than the pertussis vaccine. Main reason for refusal was a lack of maternal desire for both vaccines, but not vaccine fear. Maternal parity ≥ 1 was significantly associated with pertussis vaccine uptake at univariate analysis. Women were significantly more likely to accept the influenza vaccine if they had a university degree or if they did not deliver in a midwife-only run delivery unit in both univariate and multivariate analysis. CONCLUSIONS: In Geneva, most gynaecologists offer pertussis immunization during antenatal care and uptake is high, but more efforts must be done to increase influenza vaccination coverage. Education level impacts maternal flu vaccination uptake, but other social disparities did not.

Treatment with intravenous immunoglobulins in systemic lupus erythematosus: a single-center experience with 63 patients.

BACKGROUND: Intravenous immunoglobulin (IVIG) is prepared using purified human plasma. IVIG therapy has immunomodulatory effects on autoimmune diseases, including severe systemic lupus erythematosus (SLE). However, reports of its effects on large cohorts are scarce. METHODS: This single-center retrospective study included SLE patients treated with at least one IVIG cycle for SLE complications. Demographic data, indications, cycle numbers, and clinical improvement with IVIG were evaluated. SLE Disease Activity Index 2000 (SLEDAI-2K) scores were calculated at admission and after IVIG treatment in order to measure clinical improvement. RESULTS: Sixty-three SLE patients treated with IVIG (median age: 29 years; interquartile range 21-36 years; 84.13% female) were included, who received 2 g/kg IVIG for two to five days. Main indications were immune thrombocytopenia, hypogammaglobulinemia, infection during a SLE flare, bicytopenia, and immune hemolytic anemia. Seven patients received more than one IVIG cycle without severe adverse effects. Significant differences were found in SLEDAI-2K scores when the indications were immune thrombocytopenia and hypogammaglobulinemia, with a trend for hemolytic anemia. Patients with concomitant infection, myopathy, and gastrointestinal involvement showed a considerable reduction in their last SLEDAI-2K scores. Fourteen patients died during hospitalization, mainly due to septic shock and active SLE. CONCLUSIONS: IVIG showed adequate tolerance and effectiveness in selected severe SLE manifestations, mainly hematological involvement. It was useful for concomitant infection.

Liver damage in bleomycin-induced pulmonary fibrosis in mice.

Pulmonary fibrosis is an emerging disease with a poor prognosis and high mortality rate that is even surpassing some types of cancer. This disease has been linked to the concomitant appearance of liver cirrhosis. Bleomycin-induced pulmonary fibrosis is a widely used mouse model that mimics the histopathological and biochemical features of human systemic sclerosis, an autoimmune disease that is associated with inflammation and expressed in several corporal systems as fibrosis or other alterations. To determine the effects on proliferation, redox and inflammation protein expression markers were analyzed by immunohistochemistry. Analyses showed a significant increase in protein oxidation levels by lipoperoxidation bio-products and in proliferation and inflammation processes. These phenomena were associated with the induction of the redox status in mice subjected to 100 U/kg bleomycin. These findings clearly show that the bleomycin model induces histopathological alterations in the liver and partially reproduces the complexity of systemic sclerosis. Our results using the bleomycin-induced pulmonary fibrosis model provide a protocol to investigate the mechanism underlying the molecular alteration found in the liver linked to systemic sclerosis.

Un caso inusual de luxación posterior del codo con translocación radiocubital proximal / An unusual case of posterior elbow dislocation with proximal radioulnar translocation

Presentamos el caso de una niña de 9 años que sufrió una luxación posterior del codo derecho con translocación proximal entre el cúbito y el radio. Se trata de un tipo de luxación excepcional que en nuestro caso no se acompañó de lesiones de las superficies articulares del codo, a diferencia de la mayoría de los casos ya publicados. En este artículo se insiste en la importancia de realizar un diagnóstico precoz de esta variedad de luxación, siendo su conocimiento la mejor forma de evitar que pase desapercibida. La utilización de tomografía axial computarizada (TAC) ayudó a ese diagnóstico precoz, permitiendo realizar una reducción ortopédica cerrada inmediata y conseguir una curación sin secuelas

We present a 9-year-old girl who suffered a posterior dislocation of the right elbow with a proximal translocation between the ulna and the radius. It is a type of exceptional dislocation which in our case was not accompanied by lesions of the joint surfaces of the elbow unlike most cases already published. This article stresses the importance of making an early diagnosis of this variety of dislocation; this is the best way to prevent it from going unnoticed. The use of Computed Tomography (CT) helped this early diagnosis, enabling an immediate closed orthopaedic reduction and achieving a cure without sequelae

Toxin-antitoxin systems shows variability among Mycobacterium tuberculosis lineages.

The toxin-antitoxin (TA) systems are operons involved in the formation of persistent cells and in stress situations in microorganism. TA systems are widely distributed in Mycobacterium tuberculosis (MTB). The objective of this study was to determine the distribution and variability of protein sequences of TA systems in seven MTB lineages. Protein prediction on 73 genomes of different lineage was made using Prodigal, and profile hidden Markov models (PHMMs) of 225 reference TA proteins were constructed with HMMER. An homology search was made comparing the predicted proteins to PHMMs. Consecutive proteins that matched PHMMs (forming an operon) were selected. Thereafter, clustering of orthologous genes was made for further mutation scanning through multiple alignments. All proteins found belong to TA types II and IV, and 45 proteins were found completely conserved. Six uncharacterized antitoxins homologous to VapB11, VapB5, VapB45, VapB13, ParD1 and RelB were found. Multiple alignments revealed differences among lineages with specific mutations suitable for genotyping. Significant changes in amino acid sequences caused by frameshift mutations were found in 46 TA proteins.

Scoring severity in trauma: comparison of prehospital scoring systems in trauma ICU patients.

PURPOSE: We evaluated the predictive ability of mechanism, Glasgow coma scale, age and arterial pressure (MGAP), Glasgow coma scale, age and systolic blood pressure (GAP), and triage-revised trauma Score (T-RTS) scores in patients from the Spanish trauma ICU registry using the trauma and injury severity score (TRISS) as a reference standard. METHODS: Patients admitted for traumatic disease in the participating ICU were included. Quantitative data were reported as median [interquartile range (IQR), categorical data as number (percentage)]. Comparisons between groups with quantitative variables and categorical variables were performed using Student's T Test and Chi Square Test, respectively. We performed receiving operating curves (ROC) and evaluated the area under the curve (AUC) with its 95 % confidence interval (CI). Sensitivity, specificity, positive predictive and negative predictive values and accuracy were evaluated in all the scores. A value of p < 0.05 was considered significant. RESULTS: The final sample included 1361 trauma ICU patients. Median age was 45 (30-61) years. 1092 patients (80.3 %) were male. Median ISS was 18 (13-26) and median T-RTS was 11 (10-12). Median GAP was 20 (15-22) and median MGAP 24 (20-27). Observed mortality was 17.7 % whilst predicted mortality using TRISS was 16.9 %. The AUC in the scores evaluated was: TRISS 0.897 (95 % CI 0.876-0.918), MGAP 0.860 (95 % CI 0.835-0.886), GAP 0.849 (95 % CI 0.823-0.876) and T-RTS 0.796 (95 % CI 0.762-0.830). CONCLUSIONS: Both MGAP and GAP scores performed better than the T-RTS in the prediction of hospital mortality in Spanish trauma ICU patients. Since these are easy-to-perform scores, they should be incorporated in clinical practice as a triaging tool.

[Three successive fractures of different hip femoral stems on the same patient]. / Tres roturas sucesivas de los vástagos protésicos de cadera implantados en una paciente.

The clinical case of an 80-year-old female who suffered three fractures in uncemented stems implanted in her right hip in a period of three years is presented. A fracture occurred in the prosthetic neck and the other two at the juncture of the conical and cylindrical stem portion, coinciding with the metaphyseal-diaphyseal junction of the femur. The main causes of the failure were an increasing concentration of forces at the level of the implant as a consequence of the increased length of the neck and lateralization of the femur (offset). Other causes that have contributed to this prosthetic failure are analyzed.

Se presenta el caso clínico de una paciente de 80 años que sufrió tres roturas de vástagos protésicos no cementados implantados en su cadera derecha en un período de tres años. Una rotura ocurrió en el cuello protésico y las otras dos en la unión de la porción cónica y cilíndrica del vástago, coincidiendo con la zona metafiso-diafisaria del fémur. La causas principales del fallo han sido un incremento de la concentración de fuerzas a nivel del implante como consecuencia del aumento de la longitud del cuello y de la lateralización femoral (offset). Se analizan otras causas que han podido contribuir a dicho fallo protésico.

Mortality prediction using TRISS methodology in the Spanish ICU Trauma Registry (RETRAUCI) / Predicción de la mortalidad a través de la metodología TRISS en el Registro Español de Trauma en UCI (RETRAUCI)

OBJECTIVES: To validate Trauma and Injury Severity Score (TRISS) methodology as an auditing tool in the Spanish ICU Trauma Registry (RETRAUCI). DESIGN: A prospective, multicenter registry evaluation was carried out. SETTING: Thirteen Spanish Intensive Care Units (ICUs). PATIENTS: Individuals with traumatic disease and available data admitted to the participating ICUs. INTERVENTIONS: Predicted mortality using TRISS methodology was compared with that observed in the pilot phase of the RETRAUCI from November 2012 to January 2015. Discrimination was evaluated using receiver operating characteristic (ROC) curves and the corresponding areas under the curves (AUCs) (95% CI), with calibration using the Hosmer-Lemeshow (HL) goodness-of-fit test. A value of p < 0.05 was considered significant. Main variables of interest: Predicted and observed mortality. RESULTS: A total of 1405 patients were analyzed. The observed mortality rate was 18% (253 patients), while the predicted mortality rate was 16.9%. The area under the ROC curve was 0.889 (95% CI: 0.867-0.911). Patients with blunt trauma (n=1305) had an area under the ROC curve of 0.887 (95% CI: 0.864-0.910), and those with penetrating trauma (n=100) presented an area under the curve of 0.919 (95% CI: 0.859-0.979). In the global sample, the HL test yielded a value of 25.38 (p = 0.001): 27.35 (p < 0.0001) in blunt trauma and 5.91 (p = 0.658) in penetrating trauma. TRISS methodology underestimated mortality in patients with low predicted mortality and overestimated mortality in patients with high predicted mortality. CONCLUSIONS: TRISS methodology in the evaluation of severe trauma in Spanish ICUs showed good discrimination, with inadequate calibration - particularly in blunt trauma

Objetivos: Evaluar el Trauma and Injury Severity Score (TRISS) como instrumento de auditoría en el Registro Español de Trauma en UCI. Diseño: Evaluación prospectiva de un registro multicéntrico. Ámbito: Trece UCI españolas. Pacientes: Individuos con enfermedad traumática y datos completos ingresados en las UCI participantes. Intervenciones: Comparamos la mortalidad predicha por el TRISS con la observada en la fase piloto del Registro Español de Trauma en UCI desde noviembre de 2012 hasta enero de 2015. La discriminación se evaluó mediante curvas receiver operating characteristic y el valor bajo su área (IC 95%), y la calibración, mediante el test de bondad de ajuste de Hosmer-Lemeshow. Un valor de p<0,05 se consideró significativo. Principales variables de interés: Mortalidad observada y predicha. Resultados: Analizamos 1.405 pacientes. La mortalidad observada fue del 18% (253 pacientes), mientras que la predicha fue del 16,9%. El área bajo la curva receiver operating characteristic fue de 0,889 (IC 95% 0,867-0,911). Los pacientes con trauma cerrado (n=1.305) presentaron un área bajo la curva receiver operating characteristic de 0,887 (IC 95% 0,864-0,910), y aquellos con traumatismo penetrante (n=100), de 0,919 (IC 95% 0,859-0,979). En la muestra global, el test de Hosmer-Lemeshow mostró un valor de 25,38 (p=0,001), siendo de 27,35 (p<0,0001) en trauma cerrado y de 5,91 (p=0,658) en trauma penetrante. La metodología TRISS infraestimó la mortalidad en los pacientes con mortalidad predicha baja y la sobreestimó en pacientes con mortalidad predicha elevada. Conclusiones: La aplicación de la metodología TRISS en el trauma grave ingresado en las UCI españolas mostró buenos niveles de discriminación y una calibración inadecuada, especialmente en el traumatismo cerrado (AU)

Efectividad y predictores de fracaso de la ventilación mecánica no invasiva en la insuficiencia respiratoria aguda / Effectiveness and predictors of failure of noninvasive mechanical ventilation in acute respiratory failure

OBJETIVO: Evaluar la efectividad e identificar predictores de fracaso de la ventilación mecánica no invasiva en la insuficiencia respiratoria aguda. DISEÑO: Estudio retrospectivo, longitudinal y descriptivo. ÁMBITO: Pacientes adultos con insuficiencia respiratoria aguda. PACIENTES: Un total de 410 pacientes (muestra consecutiva) tratados mediante ventilación mecánica no invasiva en una unidad de cuidados intensivos de un hospital universitario terciario entre 2006 y 2011. INTERVENCIONES: Ventilación mecánica no invasiva. VARIABLES PRINCIPALES DE INTERÉS: Variables demográficas, clínicas y analíticas desde el inicio de la ventilación mecánica no invasiva y 2h después. Variables evolutivas durante el ingreso en la unidad y hasta el alta hospitalaria. RESULTADOS: El fracaso fue del 50%, y la mortalidad global del 33%. Un total de 156 pacientes presentaban insuficiencia respiratoria aguda hipoxémica, 87 insuficiencia respiratoria postextubación, 78 reagudización de enfermedad pulmonar obstructiva crónica, 61 insuficiencia respiratoria hipercápnica sin enfermedad pulmonar obstructiva crónica y 28 edema pulmonar agudo cardiogénico. El fracaso fue del 74, del 54, del 27, del 31 y del 21%, respectivamente. El tipo de insuficiencia respiratoria, la bilirrubina sérica al inicio, APACHEII, la existencia de hallazgos radiológicos, la necesidad de sedación para tolerarla y los cambios en el nivel de consciencia, ratio PaO2/FiO2, frecuencia respiratoria y frecuencia cardiaca entre el inicio y 2 h después se asociaron con el fracaso. CONCLUSIONES: La efectividad de la técnica varió dependiendo del tipo de insuficiencia respiratoria. Su uso en la insuficiencia respiratoria aguda hipoxémica y la insuficiencia respiratoria postextubación debería valorarse individualmente. Los predictores de fracaso podrían ser útiles para prevenir el retraso en la intubación orotraqueal

OBJECTIVE: To assess the effectiveness and identify predictors of failure of noninvasive ventilation. DESIGN: A retrospective, longitudinal descriptive study was made. SETTING: Adult patients with acute respiratory failure. PATIENTS: A total of 410 consecutive patients with noninvasive ventilation treated in an Intensive Care Unit of a tertiary university hospital from 2006 to 2011. PROCEDURES: Noninvasive ventilation. MAIN VARIABLES OF INTEREST: Demographic variables and clinical and laboratory test parameters at the start and two hours after the start of noninvasive ventilation. Evolution during admission to the Unit and until hospital discharge. RESULTS: The failure rate was 50%, with an overall mortality rate of 33%. A total of 156 patients had hypoxemic respiratory failure, 87 postextubation respiratory failure, 78 exacerbation of chronic obstructive pulmonary disease, 61 hypercapnic respiratory failure without chronic obstructive pulmonary disease, and 28 had acute pulmonary edema. The failure rates were 74%, 54%, 27%, 31% and 21%, respectively. The etiology of respiratory failure, serum bilirubin at the start, APACHEII score, radiological findings, the need for sedation to tolerate noninvasive ventilation, changes in level of consciousness, PaO2/FIO2 ratio, respiratory rate and heart rate from the start and two hours after the start of noninvasive ventilation were independently associated to failure. CONCLUSIONS: The effectiveness of noninvasive ventilation varies according to the etiology of respiratory failure. Its use in hypoxemic respiratory failure and postextubation respiratory failure should be assessed individually. Predictors of failure could be useful to prevent delayed intubation
