OBJECTIVE: Our network meta-analysis aimed to determine the assistant efficacy of targeted therapy in combined with chemotherapy for advanced/metastatic triple-negative breast cancer (TNBC). RESULTS: A total of 15 randomized controlled trials (RCTs), involving 2,410 patients, met our inclusion criteria. Eight targeted agents involving 11 treatment arms were included. The methodological quality of included RCTs was acceptable. The results of direct comparisons showed that progression-free survival (PFS) was significantly longer with bevacizumab+chemotherapy when compared to chemotherapy alone (hazard ratio [HR] = 0...

Infertility affects a remarkable one in four couples in developing countries. Psychological stress is a ubiquitous facet of life, and while stress affects us all at some point, prolonged or unmanageable stress may become harmful for some individuals, negatively impacting on their health, including fertility. For instance, women who struggle to conceive are twice as likely to suffer from emotional distress than fertile women. Assisted reproductive technology treatments place an additional physical, emotional and financial burden of stress, particularly on women, who are often exposed to invasive techniques associated with treatment...

BACKGROUND: Opioid and cocaine antenatal substance use can result in significant obstetric and pediatric health implications. Accurate detection of in utero exposed neonates can improve patient care and health outcomes. Therefore, the effectiveness of mother-infant biological and diagnostic indicators collected at labor and delivery to provide accurate detection of in utero opiate and cocaine exposure was assessed. METHODS: A retrospective medical chart review included 335 mother-infant dyads exposed to antenatal substances who were delivered between January 2009 and March 2014...

Defining thresholds of prognostic markers is essential for stratified medicine. Such thresholds are mostly estimated from purely statistical measures regardless of patient preferences potentially leading to unacceptable medical decisions. Quality-Adjusted Life-Years are a widely used preferences-based measure of health outcomes. We develop a time-dependent Quality-Adjusted Life-Years-based expected utility function for censored data that should be maximized to estimate an optimal threshold. We performed a simulation study to compare estimated thresholds when using the proposed expected utility approach and purely statistical estimators...

PURPOSE: Experimental animal models of acute respiratory distress syndrome (ARDS) have shown that the updated airway pressure release ventilation (APRV) methodologies may significantly improve oxygenation, maximize lung recruitment, and attenuate lung injury, without circulatory depression. This led us to hypothesize that early application of APRV in patients with ARDS would allow pulmonary function to recover faster and would reduce the duration of mechanical ventilation as compared with low tidal volume lung protective ventilation (LTV)...

Healthcare in general, and surgery/interventional care in particular, is evolving through rapid advances in technology and increasing complexity of care with the goal of maximizing quality and value of care. While innovations in diagnostic and therapeutic technologies have driven past improvements in quality of surgical care, future transformation in care will be enabled by data. Conventional methodologies, such as registry studies, are limited in their scope for discovery and research, extent and complexity of data, breadth of analytic techniques, and translation or integration of research findings into patient care...

BACKGROUND: Methods to identify preventable adverse events typically have low yield and efficiency. We refined the methods of Institute of Healthcare Improvement's Global Trigger Tool (GTT) application and leveraged electronic health record (EHR) data to improve detection of preventable adverse events, including diagnostic errors. METHODS: We queried the EHR data repository of a large health system to identify an 'index hospitalization' associated with care escalation (defined as transfer to the intensive care unit (ICU) or initiation of rapid response team (RRT) within 15 days of admission) between March 2010 and August 2015...

Doxorubicin (DOX)-resistance in breast cancer largely results from the breast cancer stem cell-like cells (BCSCs) which could be targeted to improve the efficacy of chemotherapy. Cell permeabilization using microbubbles (MB) and ultrasound (US) have the potential for delivering molecules into the cytoplasm. We aim to evaluate a new methodology of US on BCSCs. First, our findings indicated that ALDHA1(+) spheres which were derived from fresh primary breast cancer samples displayed stem cell-like features and were resistant to DOX...

BACKGROUND: Neuromodulatory interventions like transcranial direct current stimulation (tDCS) is emerging as a potential therapeutic strategy to promote cognitive function in healthy and pathological aging. There is need for more studies evaluating the utility and tolerability of tDCS in Mild cognitive impairment (MCI). Since MCI is considered as the prodromal stage of dementia, it has emerged as the most important target for intervention in dementia. OBJECTIVE AND METHOD: This study investigated the feasibility, tolerability and clinical utility of tDCS in patients with MCI...

Advances in high throughput sequencing technologies have created a gap between data production and functional data analysis. Indeed, phenotypes result from interactions between numerous genes, but traditional methods treat loci independently, missing important knowledge brought by network-level emerging properties. Therefore, detecting selection acting on multiple genes affecting the evolution of complex traits remains challenging. In this context, gene network analysis provides a powerful framework to study the evolution of adaptive traits and facilitates the interpretation of genome-wide data...

A knowledgeable workforce is key to meeting the demands of an aging population that is expected to nearly triple by 2030 and attitudes influence propensity to seek aging-related careers. Post-secondary education offers an opportunity to increase aging-related knowledge and facilitates intergenerational experiential-learning opportunities; however, research is lacking regarding attitudes towards aging and experiences among an academically diverse sample. To address this gap, the aims of this study were to: (1) examine differences in students' attitudes toward older adults by academic college; (2) assess differences in aging-related coursework and course experiences by academic college; and (3) explore key factors associated with students' attitudes toward older adults...

BACKGROUND: Chronic and recalcitrant wounds present a significant therapeutic challenge. Amniotic tissues contain many regenerative cytokines, growth factors, and extracellular matrix molecules including proteoglycans, hyaluronic acid, and collagens I, III, and IV. Dehydrated amnion/chorion grafts are currently used to treat a variety of wounds such as diabetic foot ulcers and burns. OBJECTIVE: The investigators hypothesized that processing methodologies, dehydration, and hypothermic processing and storage of amniotic tissues would affect overall quality of wound healing; they compared dehydrated amnion/chorion (dHACM) grafts to a novel hypothermically stored amniotic membrane (HSAM) graft in a full-thickness rat wound model...

BACKGROUND: This review is the first update of a previously published review in The Cochrane Library (Issue 7, 2015). Interleukin-5 (IL-5) is the main cytokine involved in the activation of eosinophils, which cause airway inflammation and are a classic feature of asthma. Monoclonal antibodies targeting IL-5 or its receptor (IL-5R) have been developed, with recent studies suggesting that they reduce asthma exacerbations, improve health-related quality of life (HRQoL) and lung function...
