RESUMEN

El propósito de este artículo es compartir la experiencia de la atención grupal online e interdisciplinar a embarazadas y a madres con bebés (0-6 meses de vida) con la finalidad de aumentar la contención ante las consecuencias de la pandemia actual. Constatamos la importancia de la atención primaria en red durante el período perinatal, debido a la gran cantidad de profesionales que intervienen. Así mismo, observamos que las embarazadas y madres precisan de un enfoque holístico (atendiendo las necesidades físicas y emocionales), a través de la propuesta del arrullo multisensorial, que incorpora las diferentes visiones de los profesionales en los síntomas, preocupaciones y malestares. Observamos que estos dos aspectos (la red y la atención interdisciplinar holística) permiten reducir la fragmentación asistencial y favorecer la contención emocional de las familias y los profesionales


The purpose of this article is to share the experience of online and interdisciplinary group care for pregnant women and mothers with babies (0-6 months of age) in order to increase containment when facing the consequences of the current pandemic. We highlight the importance of networked primary care during the perinatal period due to the high number of professionals involved. Similarly, we realize that pregnant women and mothers require a holistic approach (attending to physical and emotional needs) through a suggested multisensory lullaby that includes various perspectives of professionals regarding symptoms, concerns and distress. We observe that these two aspects (the network and interdisciplinary holistic care) allow to reduce healthcare fragmentation and to promote emotional containment for families and professionals

RESUMEN

Most academic precision oncology programs have been designed to facilitate enrollment of patients in early clinical trials with matched targeted agents. Over the last decade, major changes were seen both in the targetable molecular alteration landscape and in drug development trends. In this article, we describe how the Vall d'Hebron Institute of Oncology molecular prescreening program adapted to a dynamic model of biomarker-drug codevelopment. We started with a tumor-agnostic hotspot mutation panel plus in situ hybridization and immunohistochemistry of selected markers and subsequently transitioned to tumor-specific amplicon-based next-generation sequencing (NGS) tests together with custom copy number, fusion, and outlier gene expression panels. All assays are optimized for archived formalin-fixed paraffin-embedded tumor tissues without matched germline sequencing. In parallel, biomarker-matched trials evolved from a scenario of few targets and large populations (such as PI3K inhibitors in PIK3CA mutants) to a complex situation with many targets and small populations (such as multiple targetable fusion events). Recruitment rates in clinical trials with mandatory biomarkers decreased over the last 3 years. Molecular tumor board meetings proved critical to guide oncologists on emerging biomarkers for clinical testing and interpretation of NGS results. The substantial increase of immunotherapy trials had a major impact in target prioritization and guided clinical implementation of new markers, such as tumor mutational burden, with larger exon-based NGS assays and gene expression signatures to capture microenvironment infiltration patterns. This new multiomics era of precision oncology is expected to increase the opportunities for early clinical trial matching.

RESUMEN

In patients with facial trauma, multidetector computed tomography is the first-choice imaging test because it can detect and characterize even small fractures and their associated complications quickly and accurately. It has helped clinical management and surgical planning, so radiologists must communicate their findings to surgeons effectively. In Le Fort fractures, there is a breach between the pterygoid plates and the posterior maxilla. These fractures are classified in three basic patterns that can be combined and associated with various complications. Conceptualized when low-speed trauma was predominant, the Le Fort classification system has become less relevant giving more importance on maxillary occlusion-bearing segments. The classification of naso-orbito-ethmoid depends on the extent of injury to the attachment of the medial canthal tendon, with possible complications like nasofrontal duct disruption. Displaced fractures of the zygomaticomaxillary complex often widen the angle of the lateral orbital wall, resulting in increased orbital volume and sometimes in enophthalmos. Severe comminution or angulation can lead to wide surgical exposure. In orbital fractures, entrapment of the inferior rectus muscles can lead to diplopia, so it is important to assess its positioning and morphology. Orbital fractures can also result in injuries to the globe or infraorbital nerve. Frontal sinus fractures that extend through the posterior sinus wall can create a communication with the anterior cranial fossa resulting in leakage of cerebrospinal fluid, intracranial bleeding. It is essential to categorize fracture patterns and highlight features that may affect fracture management in radiology reports of facial trauma.

RESUMEN

Pleiotropy is the well-established idea that a single mutation affects multiple phenotypes. If a mutation has opposite effects on fitness when expressed in different contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce the efficacy of selection by limiting the fixation of beneficial mutations through adaptation, and the removal of deleterious mutations through purifying selection. Although this has been widely discussed, in particular in the context of a putative "gender load," it has yet to be systematically quantified. In this work, we empirically estimate to which extent different pleiotropic regimes impede the efficacy of selection in Drosophila melanogaster. We use whole-genome polymorphism data from a single African population and divergence data from D. simulans to estimate the fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction of selection (DoS). After controlling for confounding covariates, we find that the different pleiotropic regimes have a relatively small, but significant, effect on selection efficacy. Specifically, our results suggest that pleiotropic sexual antagonism may restrict the efficacy of selection, but that this conflict can be resolved by limiting the expression of genes to the sex where they are beneficial. Intermediate levels of pleiotropy across tissues and life stages can also lead to maladaptation in D. melanogaster, due to inefficient purifying selection combined with low frequency of mutations that confer a selective advantage. Thus, our study highlights the need to consider the efficacy of selection in the context of antagonistic pleiotropy, and of genetic conflict in general.

RESUMEN

This phase I trial examined the safety, pharmacokinetics, and pharmacodynamics of MLN8054, an oral, selective, small-molecule inhibitor of Aurora A kinase. Patients with advanced solid tumors received increasing doses of MLN8054 in 28-day cycles until dose-limiting toxicity (DLT) was seen in ≥2 of 3-6 patients in a cohort. For the 10-mg and 20-mg cohorts, treatment was administered once daily on days 1 to 5 and 8 to 12. Patients in later cohorts (25, 35, 45, 55, 60, 70, and 80 mg/day) were treated four times daily on days 1 to 14, with the largest dose at bedtime (QID-14D) to mitigate benzodiazepine-like effects possibly associated with peak plasma concentrations. Patients (n = 43) received a median of 1 cycle (range, 1-10). DLT of somnolence was first noted in the 20-mg cohort. Two DLTs of somnolence (n = 1) and transaminitis (n = 1) were seen at QID-14D 80 mg. Grade 2 oral mucositis (n = 1), predicted to be a mechanistic effect, was observed only at QID-14D 80 mg. MLN8054 exposure levels were roughly linear with dose; terminal half-life was 30 to 40 hours. Pharmacodynamic analyses of skin and tumor mitotic indices, mitotic cell chromosome alignment, and spindle bipolarity provided evidence of Aurora A inhibition. MLN8054 dosing for 10 to 14 days in 28-day cycles was feasible. Somnolence and transaminitis were DLTs. Pharmacodynamic analyses in mitotic cells of both skin and tumor provided proof of mechanism for Aurora A kinase inhibition. A more potent, selective, second-generation Aurora A kinase inhibitor, MLN8237, is in clinical development.

RESUMEN

BACKGROUND: Inhibition of the EGFR pathway is a useful strategy in the treatment of patients with advanced NSCLC. The aim of this study is to assess predictive clinical parameters of efficacy. METHODS AND PATIENTS: Sixty-two patients with advanced NSCLC were treated with erlotinib as second-third line (150 mg/day). Baseline patient characteristics were: performance status (PS) 1: 92%; median age, 58 years; males, 73%; adenocarcinoma, 45%; current/former smokers, 83%. During erlotinib treatment, 35% of patients had no rash, 32.3% had grade 1 rash, 26% had grade 2 rash and 6.5% patients developed grade 3 rash. RESULTS: For patients with grades 2-3 rash vs. those with grades 0-1 rash, time to tumor progression (TTP) and overall survival (OS) were 92 vs. 41 days (p=0.0381) and 244 vs. 131 days (p=0.011), respectively. For patients with non-smoking history and current/former smokers, TTP and OS were 136 vs. 42 days (p=0.0015) and 324 vs. 133 days (p=0.0242), respectively. In addition, rash grade and smoking history were found to have a highly significant impact on TTP and OS, according to the Cox model. CONCLUSIONS: Grade > or =2 rash and non-smoking history are associated with improved TTP and OS in advanced NSCLC patients treated with erlotinib.

RESUMEN

PURPOSE: To examine potential markers of clinical benefit and the effects of erlotinib on the epidermal growth factor receptor (EGFR) signaling pathway in advanced non-small cell lung cancer patients refractory to platinum-based chemotherapy. EXPERIMENTAL DESIGN: Patients were given erlotinib (150 mg/d). Tumor biopsies were done immediately before treatment and in a subgroup of patients after 6 weeks' treatment. RESULTS: Of 73 evaluable patients, 7 (10%) had partial response and 28 (38%) had stable disease. In 53 patients with baseline tumor samples, no relationship was observed between pretreatment levels of EGFR, phosphorylated (p)-EGFR, p-AKT, p-mitogen-activated protein kinase (MAPK), or p27 and clinical benefit (i.e., response, or stable disease >/=12 weeks). Tumors from 15 of 57 patients had high EGFR gene copy number, assessed using fluorescence in situ hybridization (FISH positive), 10 of whom had clinical benefit, compared with 5 of 42 FISH-negative patients. FISH-positive patients had longer median progression-free [137 versus 43 days, P = 0.002; hazard ratio (HR), 0.37] and overall (226 versus 106 days, P = 0.267; HR, 0.70) survival than FISH-negative patients. In paired biopsy samples from 14 patients, p-EGFR (P = 0.002), p-MAPK (P = 0.001), and Ki-67 (P = 0.025) levels were significantly reduced after 6 weeks' treatment. Apoptosis was significantly increased in patients with clinical benefit (P = 0.029), and may be a marker of clinical benefit. CONCLUSION: In this study, EGFR FISH-positive status was associated with improved outcome after erlotinib therapy. Erlotinib led to reduced levels of p-EGFR, p-MAPK, and Ki-67, and stimulated apoptosis in tumor samples from patients with clinical benefit.
