Hematopoietic stem cell transplantation (HCT) has been an integral component in the treatment of many hematologic malignancies. Since the development of HCT nearly 50 years ago, the role of this modality has evolved as newer treatment approaches have been developed and integrated into the standard of care. In the last decade, novel and highly active targeted therapies and immunotherapies have been approved for many hematologic malignancies, raising the question of whether HCT continues to retain its prominent role in the treatment paradigms of various hematologic malignancies. In this review, the authors have described the current role of autologous and allogeneic HCT in the treatment of patients with acute leukemias, aggressive B-cell lymphomas, and multiple myeloma and discussed how novel targeted therapies and immunotherapies have changed the potential need, timing, and goal of HCT in patients with these diseases. © 2020 American Cancer Society.in English, Spanish ANTECEDENTES Dos ensayos clínicos aleatorizados y controlados (randomized controlled trials, RCTc) (AVOD y DIABOLO) no mostraron diferencias en la recuperación ni en los resultados adversos al tratar la diverticulitis aguda no complicada sin antibióticos. Ambos ensayos mostraron tasas más altas, estadísticamente no significativas, de diverticulitis complicada y cirugía en los grupos sin antibióticos. Este metaanálisis de datos individuales de pacientes tuvo como objetivo explorar resultados adversos e identificar pacientes en riesgo que pudieran beneficiarse del tratamiento con antibióticos. MÉTODOS Se agruparon los datos individuales de pacientes con diverticulitis no complicada de dos RCT. Los factores de riesgo para los resultados adversos y el efecto del tratamiento observacional (sin antibióticos) se evaluaron mediante un análisis de regresión logística. Una P  13,5 x 109 /L y los antecedentes de diverticulitis fueron factores de riesgo para un resultado adverso. El tratamiento con antibióticos no previno los resultados adversos en pacientes con alto riesgo. CONCLUSIÓN El tratamiento de la diverticulitis aguda no complicada basado en la observación es seguro. No obstante, persiste una cierta incertidumbre desde el punto de vista estadístico, dependiendo de los umbrales de relevancia clínica, debido a pequeñas diferencias, pero no fue evidente ningún subgrupo que se pudiera beneficiar del tratamiento con antibióticos.BACKGROUND MET signaling is a well described mechanism of resistance to anti-EGFR therapy, and MET overexpression is common in head and neck squamous cell carcinomas (HNSCCs). In the current trial, the authors compared the oral MET inhibitor tivantinib (ARQ197) in combination with cetuximab (the TC arm) versus a control arm that received cetuximab monotherapy (C) in patients with recurrent/metastatic HNSCC. METHODS In total, 78 evaluable patients with cetuximab-naive, platinum-refractory HNSCC were enrolled, including 40 on the TC arm and 38 on the C arm (stratified by human papillomavirus [HPV] status). Patients received oral tivantinib 360 mg twice daily and intravenous cetuximab 500 mg/m2 once every 2 weeks. The primary outcome was the response rate (according to Response Evaluation Criteria in Solid Tumors, version 1.1), and secondary outcomes included progression-free and overall survival. After patients progressed on the C arm, tivantinib monotherapy was optional. RESULTS The response rate was 7.5% in t © 2020 American Cancer Society.OBJECTIVES This study generates a series of narrow-sense heritability estimates for crown morphology of the deciduous and permanent dentition with two overarching aims. The first is to test the hypothesis that deciduous teeth provide a more faithful reflection of genetic information than their permanent successors. The second is to use quantitative genetic methods to evaluate assumptions underlying common data collection and analysis practices in biodistance research. MATERIALS AND METHODS Dental morphology data were collected from longitudinal dental casts representing Australian twins and families using Arizona State Dental Anthropology System standards. Polygenic models and estimates of narrow-sense heritability were generated using SOLAR v.8.1.1. Each model considered age, sex, and age/sex interaction as covariates. RESULTS Heritability estimates significantly differed from zero for the majority of morphological crown characters. Most estimates fell within the 0.4-0.8 range typically observed for crown morphology. Mean heritability was stable across the dental complex, but for paired homologues, permanent traits often yielded higher estimates than their deciduous counterparts. APX2009 datasheet Results indicate directional asymmetry in environmental influence for crown morphology and inform biodistance "best practices" related to data collection and treatment. CONCLUSIONS Overall, results for this sample support the use of crown morphology as a proxy for genetic variation in evolutionary research. This includes the deciduous dentition, which justifies the expansion of efforts to incorporate subadults into reconstructions of past microevolutionary processes. Results do not indicate that deciduous phenotypes more closely approximate underlying genotype, at least for deciduous/permanent homologues. © 2020 Wiley Periodicals, Inc.In surveillance studies of periodontal disease, the relationship between disease and other health and socioeconomic conditions is of key interest. To determine whether a patient has periodontal disease, multiple clinical measurements (eg, clinical attachment loss, alveolar bone loss, and tooth mobility) are taken at the tooth-level. Researchers often create a composite outcome from these measurements or analyze each outcome separately. Moreover, patients have varying number of teeth, with those who are more prone to the disease having fewer teeth compared to those with good oral health. Such dependence between the outcome of interest and cluster size (number of teeth) is called informative cluster size and results obtained from fitting conventional marginal models can be biased. We propose a novel method to jointly analyze multiple correlated binary outcomes for clustered data with informative cluster size using the class of generalized estimating equations (GEE) with cluster-specific weights. We compare our proposed multivariate outcome cluster-weighted GEE results to those from the convectional GEE using the baseline data from Veterans Affairs Dental Longitudinal Study.
