Background and purpose: Glioblastoma multiforme (GBM) is the most common malignant primary anomaly of central nervous system. The GBM infiltrates the nearly sturctures from the initial tumor and its metastatic attribution is well known. The aim of our single-centered retrospective study was to introduce the importance of postoperative medical imaging confirmation of total tumor resection for patient with GBM combined concomitant and adjuvant chemoradiotherapy on a 10 year long patient follow up...

AIM: Pompe disease is a rare, autosomal, recessive disorder. Alterations in the gene encoding lysosomal acid alpha-glucosidase cause impaired glycogen degradation and resultant lysosomal glycogen accumulation. Classic infantile-onset Pompe disease (IPD) manifests soon after birth, severe cases have complete/near complete enzyme deficiency. IPD is associated with a broad spectrum of non-specific clinical features, and diagnostic delays are common. Without treatment, death typically occurs within the first 2 years of life...

Nanocomposites for integrating imaging and therapy have attracted tremendous attention for biomedical applications. Herein, Fe@Bi2S3 nanocomposites modified with polyethylene glycol (PEG) molecules are fabricated for synergistic thermoradiotherapy. For such nanocomposites, Bi2S3 exhibits a strong absorbance in the near-infrared (NIR) region, which allows Bi2S3 to convert energy from light into heat for effective photothermal therapy (PTT), whereas Bi can also significantly enhance radio-mediated cell death induction as a radiotherapy sensitizer due to its high atomic number (high-Z)...

Breast cancer is the most common cancer in women worldwide; despite the developments in diagnosis and therapy, recurrence and metastasis remain the main causes of death among patients with breast cancer. This study aimed to identify a promising biomarker for this disease. The study clarified (1) the association between Friend leukemia virus integration 1 (FLI-1) and various molecular subtypes and (2) the prognostic value of FLI-1 in breast cancer. To the best of our knowledge, this study is the first to report that FLI-1 is a predictor of poor prognosis in patients with breast cancer and overexpressed in the triple negative breast cancer (TNBC) subtype...

Recently, near-infrared (NIR) light responsive drug delivery systems have attracted much attention for tumor therapy. Herein, we have successfully constructed a smart nanocarrier system Cu9S5-PEI-DNA-DOX (labelled as CPD-DOX) based on the self-assembly of hydrophobic Cu9S5 nanoparticles (NPs), poly(ethylene imine) (PEI), double-stranded DNA (dsDNA) segments and the anti-cancer drug doxorubicin (DOX). Among them, Cu9S5 NPs can serve as a nano-transducer for absorbing and converting near-infrared light to heat...

PURPOSE: We explored pediatricians' practices and attitudes concerning end-of-life discussions (EOLds) with pediatric patients with cancer, and identified the determinants of pediatricians' positive attitude toward having EOLds with pediatric patients. METHODS: A multicenter questionnaire survey was conducted with 127 pediatricians specializing in the treatment of pediatric cancer. RESULTS: Forty-two percent of participants reported that EOLds should be held with the young group of children (6-9 years old), 68% with the middle group (10-15 years old), and 93% with the old group (16-18 years old)...

Photodynamic therapy (PDT) has increasingly become an efficient and attractive cancer treatment modality based on reactive oxygen species (ROS) that can induce tumor death after irradiation with ultraviolet or visible light. Herein, to overcome the limited tissue penetration in traditional PDT, a novel near-infrared (NIR) light-activated NaScF4 : 40% Yb, 2% Er@CaF2 upconversion nanoparticle (rUCNP) is successfully designed and synthesized. Chlorin e6, a photosensitizer and a chelating agent for Mn2+ , is loaded into human serum albumin (HSA) that further conjugates onto rUCNPs...

Patients with advanced myeloma experience a high symptom burden particularly near the end of life, making timely hospice use crucial. Little is known about the quality and determinants of end-of-life care for this population, including if potential increases in hospice use are also accompanied by "late" enrollment (≤ 3 days before death). Using the Surveillance, Epidemiology, and End-Results-Medicare database, we identified patients ≥ 65 years diagnosed with myeloma between 2000 and 2013 that died by December 31, 2013...

Staphylococcus epidermidis (S. epidermidis) is one of the leading nosocomial pathogens, particularly associated with periprosthetic infections of biomedical implants. Silicon nitride (Si3N4), a nonoxide biomaterial widely used in spinal implants, has shown bacteriostatic effects against both gram-positive and gram-negative bacteria; however, the physicochemical interactions between Si3N4 and bacteria yet remain conspicuously unexplored. In situ time-lapse Raman spectroscopic experiments were conducted by exposing S...

BACKGROUND: Cancer is a leading cause of death among women of parenting age in the United States. Women living with advanced or incurable cancer who have dependent children experience high rates of depression and anxiety as well as unique parenting challenges. To the authors' knowledge, few studies to date have examined the parenting factors associated with health-related quality of life (HRQOL) in women with advanced cancer. METHODS: The authors conducted a cross-sectional, Web-based survey of the psychosocial concerns of 224 women with a tumor-node-metastasis staging system of the AJCC stage IV solid tumor malignancy who had at least 1 child aged <18 years...

Determining the manner of death in cases involving multiple stab injuries from a knife is generally straightforward. The medico-legal investigation of a stabbing death caused by a single stab injury from a knife comprises a smaller but potentially more problematic subset of forensic cases. We reviewed our institute's experience with single stab injuries and endeavored to identify features identified at the post-mortem examination which may aid in the differentiation between cases of homicide, suicide and accidental death...

The matched-pairs design enables researchers to efficiently infer causal effects from randomized experiments. In this paper, we exploit the key feature of the matched-pairs design and develop a sensitivity analysis for missing outcomes due to truncation by death, in which the outcomes of interest (e.g., quality of life measures) are not even well defined for some units (e.g., deceased patients). Our key idea is that if 2 nearly identical observations are paired prior to the randomization of the treatment, the missingness of one unit's outcome is informative about the potential missingness of the other unit's outcome under an alternative treatment condition...

OBJECTIVE Traumatic brain injury (TBI)-the "silent epidemic"-contributes to worldwide death and disability more than any other traumatic insult. Yet, TBI incidence and distribution across regions and socioeconomic divides remain unknown. In an effort to promote advocacy, understanding, and targeted intervention, the authors sought to quantify the case burden of TBI across World Health Organization (WHO) regions and World Bank (WB) income groups. METHODS Open-source epidemiological data on road traffic injuries (RTIs) were used to model the incidence of TBI using literature-derived ratios...

This article explores the public dying of journalist, writer, provocateur, public intellectual, and renowned atheist, Christopher Hitchens. It does so primarily through an analysis of television interviews given by Hitchens following his diagnosis with esophageal cancer in June 2010. Four key themes are identified as emerging from analysis of the interviews: (a) Hitchens' explicit sense of mission in challenging myths and superstitions surrounding cancer, dying, and death; (b) the personal experience of terminal illness and dying and the particular way (or style of dying) by which it is approached; (c) issues of regret and a life well lived; and (d) questions surrounding religion, the afterlife, and possibility of deathbed conversion...

BACKGROUND: The environment for medical education in Iraq has been difficult for many years. The 2003 invasion of Iraq accelerated a steady emigration of faculty and graduates. Kidnappings and deaths of doctors became commonplace. To understand current career plans, expectations and perceptions of medical students, three Baghdad medical schools were surveyed. METHODS: Written questionnaires were completed by 418 medical students variously in their 4th, 5th and 6th (final)years of training...

OBJECTIVE: Motor vehicle crashes are the leading cause of death among young drivers. Though previous research has focused on crash events, near crashes offer additional data to help identify driver errors that could potentially lead to crashes as well as evasive maneuvers used to avoid them. The Strategic Highway Research Program 2 (SHRP2) Naturalistic Driving Study (NDS) contains extensive data on real-world driving and offers a reliable methodology to quantify and study near crashes...

As wheat yield is linearly related to grain number, understanding the physiological determinants of the number of fertile florets based on floret development dynamics due to the role of the particular genes is relevant. The effects of photoperiod genes on dynamics of floret development are largely ignored. Field experiments were carried out to (i) characterize the dynamics of floret primordia initiation and degeneration and (ii) to determine which are the most critical traits of such dynamics in establishing genotypic differences in the number of fertile florets at anthesis in near isogenic lines (NILs) carrying photoperiod-insensitive alleles...
