Results from the INMUNOSUN-SOGUG trial: a prospective phase II study of sunitinib as a second-line therapy in patients with metastatic renal cell carcinoma after immune checkpoint-based combination therapy.

BACKGROUND: The INMUNOSUN trial had the objective of prospectively evaluating the efficacy and safety of sunitinib as a pure second-line treatment in patients with metastatic renal cell carcinoma (mRCC) who have progressed to first-line immune checkpoint inhibitor (ICI)-based therapies. PATIENTS AND METHODS: A multicenter, phase II, single-arm, open-label study was carried out in patients with a histologically confirmed diagnosis of mRCC with a clear-cell component who had progressed to a first-line regimen of ICI-based therapies. All patients received sunitinib 50 mg once daily orally for 4 weeks, followed by a 2-week rest period following package insert instructions. The primary outcome was the objective response rate. RESULTS: Twenty-one assessable patients were included in the efficacy and safety analyses. Four patients [19.0%, 95% confidence interval (CI) 2.3% to 35.8%] showed an objective response (OR), and all of them had partial responses. Additionally, 14 (67%) patients showed a stable response, leading to clinical benefit in 18 patients (85.7%, 95% CI 70.7% to 100%). Among the four assessable patients who showed an OR, the median duration of the response was 7.1 months (interquartile range 4.2-12.0 months). The median progression-free survival (PFS) was 5.6 months (95% CI 3.1-8.0 months). The median overall survival (OS) was 23.5 months (95% CI 6.3-40.7 months). Patients who had better antitumor response to first-line ICI-based treatment showed a longer PFS and OS with sunitinib. The most frequent treatment-emergent adverse events were diarrhea (n = 11, 52%), dysgeusia (n = 8, 38%), palmar-plantar erythrodysesthesia (n = 8, 38%), and hypertension (n = 8, 38%). There was 1 patient who exhibited grade 5 pancytopenia, and 11 patients experienced grade 3 adverse events. Eight (38%) patients had serious adverse events, four of which were considered to be related to sunitinib. CONCLUSION: Although the INMUNOSUN trial did not reach the pre-specified endpoint, it demonstrated that sunitinib is active and can be safely used as a second-line option in patients with mRCC who progress to new standard ICI-based regimens.

Hypersensitivity Reactions to Cancer Chemotherapy: Practical Recommendations of ARADyAL for Diagnosis and Desensitization.

Rapid drug desensitization has enabled first-line therapies in patients with drug hypersensitivity reactions to chemotherapeutic drugs including monoclonal antibodies. Desensitization is a safe and highly effective procedure, not only for IgE-mediated reactions, but also for those mediated by non-IgE mechanisms. The likelihood of breakthrough reactions during desensitization is low, and most are mild; in fact, moderate-to-severe reactions are infrequent. In this document, 16 allergy departments belonging to the Spanish research network ARADyAL present a review of the available scientific evidence and provide general guidelines for the diagnosis and management of drug hypersensitivity reactions to chemotherapeutic drugs and monoclonal antibodies. Emphasis is placed on the desensitization procedure.

Calidad higiénico-sanitaria de dos sistemas de ordeño en fincas bovinas ubicadas en el sector Vuelta Larga, municipio Maturín, estado Monagas (Venezuela) / Hygienic-sanitary quality of two milking systems in bovine farms located in sector Vuelta Larga, Maturín municipal state, Monagas state (Venezuela)

RESUMEN El objetivo de la presente investigación fue evaluar la calidad higiénico-sanitaria de dos sistemas de ordeño en fincas bovinas del municipio Maturín estado Monagas (Venezuela). El ensayo tuvo una duración de seis semanas, se calculó la eficiencia higiénica (%EH) de las instalaciones, el personal, la rutina de ordeño, la limpieza-desinfección y el almacenamiento-transporte de dos unidades de producción. Adicionalmente, se determinó la población de bacterias aerobias mesófilas (BAM) que se cuantificaron en un experimento en bloques al azar, con arreglo factorial de los tratamientos (2x2) donde el factor A, correspondió al sistema de ordeño manual y mecánico y el factor B, a la aplicación y omisión de secado de los pezones de cada animal previo al ordeño. La variable se examinó por análisis de varianza y sus valores promedios comparados por Tukey al 5% de probabilidad. El %EH de las fincas evaluadas fue de 66,66% para la finca 2 y de 54,84% para la finca 1, considerados no satisfactorios. Los resultados obtenidos para la variable BAM indican que el factor sistema de ordeño mostró diferencia altamente significativa (p ≤ 0,01); el sistema manual presentó el menor conteo con 5,24 Log10 UFC/ mL; mientras que para el factor condición de secado se constató diferencia significativa (p ≤ 0,05), ya que la aplicación de secado presentó la menor población de bacterias aerobias mesófilas con 5,25 Log10 UFC/mL. Las medidas higiénicas y sanitarias implementadas en la rutina de ordeño influyeron directamente en la calidad de la leche cruda.

ABSTRACT The objective of the present investigation, was to evaluate the 'Hygienic-Sanitary Quality of two Milking Systems in Bovine Farms' in Vuelta Larga Sector, Maturín City, Monagas State (Venezuela). The trial lasted six weeks, in which the Hygienic Efficiency (% EH) of the facilities, the workers, the milking routine, the cleaning and disinfection measures and the storage and transport of both milking systems, were calculated. Furthermore, the population of Mesophilic Aerobic Bacteria (BAM) was determined ; The data were processed following a distribution in random blocks with factorial arrangement (2x2) whose factor A represented the milking system: manual and mechanical, and the factor B was the application and omission of manual drying of teats for each animal prior to milking. The percentage of Hygienic Efficiency (% EH) of the farms evaluated was not satisfactory, corresponding to 66.66% in the farm 2 and 54.84% in the farm 1. The variable was examined by analysis of variance and its mean values compared by Tukey test at 5% of probability. Factor A achieved a highly significant difference (p ≤0.01), with the manual system obtaining the lowest count with 5.24 Log10 CFU / mL. In factor B significant difference was found (p≤0.05), the drying application decreased the BAM population with 5.25 Log10 CFU / mL. The Hygienic and Sanitary measures implemented in the milking routine directly influence the quality of raw milk.

The Mexican consensus on non-cardiac chest pain. / Consenso mexicano sobre dolor torácico no cardiaco.

INTRODUCTION: Non-cardiac chest pain is defined as a clinical syndrome characterized by retrosternal pain similar to that of angina pectoris, but of non-cardiac origin and produced by esophageal, musculoskeletal, pulmonary, or psychiatric diseases. AIM: To present a consensus review based on evidence regarding the definition, epidemiology, pathophysiology, and diagnosis of non-cardiac chest pain, as well as the therapeutic options for those patients. METHODS: Three general coordinators carried out a literature review of all articles published in English and Spanish on the theme and formulated 38 initial statements, dividing them into 3 main categories: (i)definitions, epidemiology, and pathophysiology; (ii)diagnosis, and (iii)treatment. The statements underwent 3rounds of voting, utilizing the Delphi system. The final statements were those that reached >75% agreement, and they were rated utilizing the GRADE system. RESULTS AND CONCLUSIONS: The final consensus included 29 statements. All patients presenting with chest pain should initially be evaluated by a cardiologist. The most common cause of non-cardiac chest pain is gastroesophageal reflux disease. If there are no alarm symptoms, the initial approach should be a therapeutic trial with a proton pump inhibitor for 2-4weeks. If dysphagia or alarm symptoms are present, endoscopy is recommended. High-resolution manometry is the best method for ruling out spastic motor disorders and achalasia and pH monitoring aids in demonstrating abnormal esophageal acid exposure. Treatment should be directed at the pathophysiologic mechanism. It can include proton pump inhibitors, neuromodulators and/or smooth muscle relaxants, psychologic intervention and/or cognitive therapy, and occasionally surgery or endoscopic therapy.

Induced Negative Mood Increases Dictator Game Giving.

The study examines the influence of induced negative mood on dictator game giving (DGG) with two recipients. Participants (N = 63) played the role of a dictator in a three-player dictator game. They could choose among two options: an altruistic option, where two receivers receive 10 Euros and the dictator himself receives nothing, or a selfish option, where the dictator himself receives 5 Euros and both receivers receive nothing. For half of the participants, the second option entailed that only one receiver receives nothing and the other receives 10 Euros. After four rounds, participants were randomly assigned to look at 10 pictures with either positive or negative emotional content with the purpose of inducing positive or negative mood. The results show that looking at pictures with negative emotional content increases anxiety and skin conductance and increases DGG in the remaining four rounds of the game. On the other hand, whether the selfish option would imply that one or both recipients receive nothing does not seem to have a strong influence on DGG. PsycINFO Classification code: 2340; 2360.

Concurrent chemoradiation for locally advanced stage III non-small cell lung cancer with cisplatin, vinorelbine, and thoracic radiotherapy: a phase II study from the Galician Lung Cancer Group.

PURPOSE: The aim of this phase II study was to evaluate the activity and safety of the combination of cisplatin and vinorelbine with thoracic radiotherapy in unresectable locally advanced stage III non-small cell lung cancer (NSCLC). The primary endpoint was the objective response rate (ORR). Secondary objectives included toxicity profile, progression-free survival (PFS), and overall survival (OS). MATERIALS AND METHODS: A total of 48 NSCLC patients were enrolled (median age 60 years, 52% stage IIIA and 48% stage IIIB, 52% adenocarcinoma). Patients received three cycles of chemotherapy every 21 days [intravenous cisplatin 80 mg/m2 and intravenous vinorelbine 25 mg/m2 on day 1 and oral vinorelbine on day 8 (60 mg/m2)] concurrent with radiotherapy (66 Gy, administered at 1.8 Gy per day, five consecutive days per week). RESULTS: ORR was 79.2% (72.9% showing partial response and 6.3% showing complete response). With a median follow-up of 20.7 months, median PFS was 12 months and median OS was 36 months. Grade 3/4 toxicities were: neutropenia (14.5%), anaemia (6.2%), vomiting (2%), and oesophagitis (4.2%). No toxic deaths were reported. CONCLUSION: This combined regimen shows efficacy and a manageable safety profile. PFS and OS outcomes are encouraging and warrant further research.

Factors increasing the risk for a severe reaction in anaphylaxis: An analysis of data from The European Anaphylaxis Registry.

BACKGROUND: Preventive measures to decrease the frequency and intensity of anaphylactic events are essential to provide optimal care for allergic patients. Aggravating factors may trigger or increase the severity of anaphylaxis and therefore need to be recognized and avoided. OBJECTIVE: To identify and prioritize factors associated with an increased risk of developing severe anaphylaxis. METHODS: Data from the Anaphylaxis Registry (122 centers in 11 European countries) were used in logistic regression models considering existing severity grading systems, elicitors, and symptoms to identify the relative risk of factors on the severity of anaphylaxis. RESULTS: We identified higher age and concomitant mastocytosis (OR: 3.1, CI: 2.6-3.7) as the most important predictors for an increased risk of severe anaphylaxis. Vigorous physical exercise (OR: 1.5, CI: 1.3-1.7), male sex (OR: 1.2, CI: 1.1-1.3), and psychological burden (OR: 1.4, CI: 1.2-1.6) were more often associated with severe reactions. Additionally, intake of beta-blockers (OR: 1.9, CI: 1.5-2.2) and ACE-I (OR: 1.28, CI: 1.05, 1.51) in temporal proximity to allergen exposition was identified as an important factor in logistic regression analysis. CONCLUSION: Our data suggest it may be possible to identify patients who require intensified preventive measures due to their relatively higher risk for severe anaphylaxis by considering endogenous and exogenous factors.

Latin America: the next region for haematopoietic transplant progress.

Haematopoietic cell transplant activity in the 28 countries comprising Latin America is poorly defined. We conducted a voluntary survey of members of the Latin American Bone Marrow Transplantation Group regarding transplant activity 2009-2012. Collated responses were compared with data of transplant rates from the Worldwide Network for Blood and Marrow Transplantation for other geographic regions. Several socio-economic variables were analysed to determine correlations with transplant rates. In total, 94 teams from 12 countries reported 11 519 transplants including 7033 autotransplants and 4486 allotransplants. Annual activity increased from 2517 transplants in 2009 to 3263 in 2012, a 30% increase. Median transplants rate (transplant per million inhabitants) in 2012 was 64 (autotransplants, median 40; allotransplants, median 24). This rate is substantially lower than that in North America and European regions (482 and 378) but higher than that in the Eastern Mediterranean and Asia Pacific regions (30 and 45). However, the Latin America transplant rate is 5-8-fold lower than that in America and Europe, suggesting a need to increase transplant availability. Transplant team density in Latin America (teams per million population; 1.8) is 3-4-fold lower than that in North America (6.2) or Europe (7.6). Within Latin America, there is substantial diversity in transplant rates by country partially explained by diverse socio-economic variables including per capita gross national income, health expenditure and physician density. These data should help inform future health-care policy in Latin America.

Transforming growth factor-ß1 functional polymorphisms in myeloablative sibling hematopoietic stem cell transplantation.

Hematopoietic stem cell transplantation (HSCT) with sibling donors (s.d.) is a life-saving intervention for patients with hematological malignancies. Numerous genetic factors have a role in transplant outcome. Several functional polymorphisms have been identified in TGF-ß1 gene, such as single-nucleotide polymorphism (SNP) at +29C>T within exon 1. Two hundred and forty five patient/donor pairs who underwent a s.d. HSCT in our centers were genotyped for this SNP. In the myeloablative cohort, +29CC donors were associated with an increase in severe chronic GvHD (32% vs 16%, hazard ratio (HR) 9.0, P=0.02). Regarding survival outcomes, +29CC patients developed higher non relapse mortality (NRM) (1-5 years CC 28-32% vs TC/TT 7-10%; HR 5.1, P=0.01). Recipients of +29TT donors experienced a higher relapse rate (1-5 years TT 37-51% vs TC 19-25% vs CC 13%-19%; HR 2.4, P=0.01) with a decreased overall survival (OS) (1-5 years TT 69-50% vs TC/CC 77-69%; HR 1.9, P=0.05). Similar to previous myeloablative unrelated donors HSCT results, we confirmed that +29CC patients had higher NRM. In addition we found that +29TT donors might be associated with a higher relapse rate and lower OS. These results should be confirmed in larger series. Identification of these SNPs will allow personalizing transplant conditioning and immunosuppressant regimens, as well as assisting in the choice of the most appropriate donor.

Impacto de la hipomineralización incisivo molar en la experiencia de caries en escolares de 6-12 años en Santiago, Chile / Molar incisor hypomineralisation and its impact on caries experienced by 6-12 year-old schoolchildren from Santiago, Chile

Objetivo: El objetivo de este estudio fue determinar las consecuencias clínicas expresadas en índices COPD y ceod y su relación con la presencia de hipomineralización incisivo molar (HIM) en una población de escolares de 6 a 12 años de la provincia de Santiago. Método: Este estudio de corte transversal fue realizado en 851 escolares de 6 a 12 años de la provincia de Santiago, quienes fueron evaluados por 2 dentistas calibrados. Con consentimiento de los tutores legales, los escolares fueron examinados, y se utilizaron los criterios diagnósticos para HIM de la Academia Europea de Odontopediatría (EAPD). La historia de caries fue determinada con COPD/ceod de acuerdo a los criterios de la OMS. Los datos fueron recolectados en una ficha especialmente diseñada para esto. Los datos fueron analizados con test «t¼ para muestras individuales (considerando p < 0,05). Resultados: Los escolares afectados por HIM tuvieron una media de COPD de 0,91 (±1,21) y una media de ceod de 1,98 (±2,48), el cual fue mayor que el COPD y ceod de escolares sin HIM (0,41 [±0,95] y 1,34 [±2,15] respectivamente). La diferencia entre ambos grupos fue estadísticamente significativa para COPD (p < 0,000) y ceod (p = 0,002). Conclusiones: Escolares de la provincia de Santiago de 6 a 12 años afectados con HIM presentaron mayor COPD/ceod que escolares sin HIM.

Objective. The aim of this study was to determine the clinical consequences, expressed in DMFT and dmft, and their relationship with Molar Incisor Hypomineralisation (MIH) in a population of schoolchildren of 6 to 12 years old in the Santiago Province. Method: A cross-sectional study was conducted on 851 schoolchildren between 6-12 years old from the Santiago Province were examined by two calibrated examiners. With informed consent from their parents, the schoolchildren were examined, and the European Academy of Paediatric Dentistry (EAPD) diagnostic criteria was used for MIH detection. Caries history was assessed with the DMFT/dmft score according to WHO criteria. Data was collected with a form specially designed for this study. Data was analysed using Student's t-test for individual samples and a post-hoc Bonferroni (P < .05). Results: The mean DMFT score in the MIH-affected schoolchildren was 0.91 (±1.21), with a mean dmft score of 1.98 (±2.48), which were greater than the scores in the non-MIH affected schoolchildren (mean DMFT score 0.41 [±0.95] and mean dmft 1.34 [±2.15]). The differences between DMFT and dmft scores in the two groups were statistically significant (P < .000 and P = .002, respectively). Conclusions: Schoolchildren of Santiago Province of 6-12 year old diagnosed with MIH had higher DMFT/dmft scores compared to schoolchildren not affected with MIH.

Cetoacidosis diabética normoglicémica en el embarazo: caso clínico / Normoglycemic diabetic ketoacidosis in pregnancy: report of one case

Normoglycemic diabetic ketoacidosis should be suspected in pregnant women presenting nausea, vomiting, abdominal pain and anorexia. We report a 39 years old woman with a 32 weeks pregnancy who sought emergency care due to hyperemesis. She was hospitalized with the following diagnoses: pregnancy hypertension syndrome, gestational diabetes, morbid obesity and poor prenatal control. The evaluation of the feto-placental unit showed perception of fetal movements, non-reactive non-stress baseline record and a biophysical profile of 6/8. Fetal maturation was initiated. Laboratory tests showed a metabolic acidosis, a low pH, an increased Gap anion, elevated ketonemia and a blood glucose of 172 mg/dl. A diagnosis of normoglycemic diabetic ketoacidosis was formulated and treatment with hydration and regular insulin according to capillary blood glucose levels was started. An emergency caesarean section was performed. The newborn weighed 2.650 kg, had a length of 46 cm, was large for gestational age, had an Apgar score of 2.7, had perinatal asphyxia, convulsive syndrome and a possible congenital cardiopathy. Once the ketoacidosis was resolved during the immediate puerperium, slow acting insulin was initiated.
