OBJECTIVE: Intensive care delirium is a substantial problem in adults. Intensive care delirium is increasingly recognized in pediatrics in parallel with the development of specific scoring systems for children. However, little is known about the fluctuating course of intensive care delirium in children after surgery and possible implications on diagnostic and therapeutic strategies. DESIGN: Patients that needed treatment in the PICU following elective surgery were screened for intensive care delirium with the Cornell Assessment of Pediatric Delirium...

"Morbidly adherent placenta" is a term that describes the continuum of placenta accreta, increta, and percreta. The incidence of this type of abnormal placentation has increased significantly over recent decades. The reason is probably multifactorial but, partly, because of factors such as the increasing number of cesarean births. Women at greatest risk are those who have myometrial damage caused by a previous cesarean birth, with either anterior or posterior placenta previa overlying the uterine scar. This condition poses significant risks of morbidity and/or mortality to the pregnant woman and her fetus...

OBJECTIVE: Sleep-disordered breathing (SDB) is among the most common diseases and includes a group of pathological conditions that form a severity continuum from primary snoring (PS) to obstructive sleep apnea (OSA). SDB presents a multifactorial etiology and in children, it is often linked to adenotonsillar hypertrophy, which may lead to an alteration of the breathing pattern. Therefore, several studies hinted at the existence of a correlation between SDB and the alteration of craniofacial growth...

This article examines the adult perceptions of women survivors of intrafamilial child sexual abuse and their current relationship with the family member who abused them in their childhood. Twenty Jewish Israeli women were interviewed in depth between 2008 and 2009. Interviews were tape-recorded and transcribed verbatim. Data analysis produced 2 interrelated continua with regard to the presence of the perpetrator in the women's life: a continuum of his actual daily presence in the woman's living space, ranging from complete absence to a continuous presence, and a continuum of his experiential presence, ranging from a high level of intrusiveness to encapsulation and total dissociation...

We consider cancer chemotherapy as an optimal control problem with the aim to minimize a combination of the tumor volume and side effects over an a priori specified therapy horizon when the tumor consists of a heterogeneous agglomeration of many subpopulations. The mathematical model, which accounts for different growth and apoptosis rates in the presence of cell densities, is a finite-dimensional approximation of a model originally formulated by Lorz et al. [18,19] and Greene et al. [10,11] with a continuum of possible traits...

INTRODUCTION: Remarkable strides have been made in controlling the HIV epidemic, although not enough to achieve epidemic control. More recently, interest in biomedical HIV control approaches has increased, but substantial challenges with the HIV cascade of care hinder successful implementation. We summarise all available HIV prevention methods and make recommendations on how to address current challenges. DISCUSSION: In the early days of the epidemic, behavioural approaches to control the HIV dominated, and the few available evidence-based interventions demonstrated to reduce HIV transmission were applied independently from one another...

This commentary focuses on the tenuous line between health and disease and the conflicting characterizations of genetic predisposition that sometimes place it on one side of that line, and sometimes on the other. For example, GINA uses the line between health and disease to distinguish between, respectively, the healthy (including, those with genetic predispositions), who are shielded from discrimination, and those with 'manifested illness,' who are not. At the same time, some have argued that the Americans with Disabilities Act protects individuals with genetic predispositions, relying on a label akin to disability, as opposed to health, to characterize this group...

: Glucose-regulated protein (GRP)-78, the key regulator of endoplasmic reticulum (ER) stress, is associated with endometrial cancer (EC) development and progression. However, its role in the continuum from complex atypical hyperplasia (CAH) to EC is unknown and the focus of this study. METHODS: 252 formalin-fixed, paraffin-embedded endometrial biopsies from patients with CAH diagnosed between 2003 and 2011 were evaluated for GRP78 expression by immunohistochemistry...

OBJECTIVE: This study was aimed to find out epidemiologic characteristic of tuberculosis (TB) cases, and Human Immunodeficiency Virus (HIV) positive cases among TB patients (TB/HIV co-infection) through demographic, temporal, and spatial study in Urumqi. METHODS: Descriptive statistics and multivariate logistic regression were applied to identify the epidemiologic characteristics and risk factors of TB epidemic and TB/HIV co-infection epidemic. All addresses of each TB case, TB/HIV co-infection case, and administrative street were transformed into geographical coordinate...

BACKGROUND: Patients who are newly screened HIV positive by EIA are lost to follow-up due to complicated HIV testing procedures. Because this is the first step in care, it affects the entire continuum of care. This is a particular concern in rural China. OBJECTIVE(S): To assess the routine HIV testing completeness and treatment initiation rates at 18 county-level general hospitals in rural Guangxi. METHODS: We reviewed original hospital HIV screening records...

BACKGROUND: Hepatitis C virus (HCV) infection is hyperendemic among people who inject drugs; nonsterile drug injection is the principle risk for HCV acquisition. Due to gaps in the HCV care continuum, there have been recommendations in the United States emphasizing age-rather than risk-based testing strategies. The central research focus of this project is to explore the meanings and implications of the shift in emphasis from risk-based to age-based HCV testing with regard to people who use drugs...

The processes underlying perceptual decision making are diverse and typically engage a distributed network of brain areas. It is a particular challenge to establish a sensory-to-motor functional hierarchy in such networks. This is because single-cell recordings mainly study the nodes of decision networks in isolation but seldom simultaneously. Moreover, imaging methods, which allow simultaneously accessing information from overall networks, typically suffer from either the temporal or the spatial resolution necessary to establish a detailed functional hierarchy in terms of a sequential recruitment of areas during a decision process...

Obesity, insulin resistance, type 2 diabetes mellitus and cardiovascular disease form a metabolic disease continuum that has seen a dramatic increase in prevalence in developed and developing countries over the past two decades. Dyslipidaemia resulting from hypercaloric diets is a major contributor to the pathogenesis of metabolic disease, and lipid-lowering therapies are the main therapeutic option for this group of disorders. However, the fact that dysfunctional lipid metabolism extends far beyond cholesterol and triglycerides is becoming increasingly clear...

The reactions of α-hydroxyalkyl radicals in aqueous medium are of interest because they exhibit a rich variety of fundamentally important competing mechanisms, such as proton-coupled electron transfer (PCET), hydrogen atom transfer, free radical substitutions, abstractions and additions etc. We present a theoretical study of the mechanism and kinetics of the aqueous reactions of α-hydroxyisopropyl (2-propanol) radical with four halogenated organic substrates: iodoacetate (IAc), iodoacetamide (IAm), 5-bromouracil (5-BrU), and carbon tetrachloride (CCl4)...

OBJECTIVE: To provide an updated synthesis of the literature that investigates the self-reported information needs of people diagnosed with cancer across the cancer continuum. METHODS: We conducted a scoping review of the literature published from August 2003 to June 2015 and expanded an existing typology summarizing the information needs of people diagnosed with cancer. RESULTS: The majority of the included studies (n=104) focused on questions relevant to the diagnosis/active treatment phase of the cancer continuum (52...

PURPOSE OF REVIEW: Recovery after surgery is a complex interplay of the patient, the surgery, and the perioperative anaesthesia management. Assessment of recovery should address the needs of multiple stakeholders, including the institutions and healthcare providers, but primarily should be focused on the patients and their perception of quality of recovery and return to normalcy. This review will summarize the development of assessment of recovery to a multidimensional dichotomous construct that requires a real-time assessment tool validated for repeat measures and containing cognitive assessment...

OBJECTIVE: To apply the principles of the Metro-ticket paradigm to develop a prognostic model for patients undergoing hepatic resection of colorectal liver metastasis (CRLM). BACKGROUND: Whereas the hepatocellular "Metro-ticket" prognostic tool utilizes a continuum of tumor size and number, a similar concept of a CRLM Metro-ticket paradigm has not been investigated. METHODS: Tumor Burden Score (TBS) was defined using distance from the origin on a Cartesian plane incorporating maximum tumor size (x-axis) and number of lesions (y-axis)...

Millions of years of evolution have fine-tuned the ability of venom peptides to rapidly incapacitate both prey and potential predators. Toxicofera reptiles are characterized by serous-secreting mandibular or maxillary glands with heightened levels of protein expression. These glands are the core anatomical components of the toxicoferan venom system, which exists in myriad points along an evolutionary continuum. Neofunctionalisation of toxins is facilitated by positive selection at functional hotspots on the ancestral protein and venom proteins have undergone dynamic diversification in helodermatid and varanid lizards as well as advanced snakes...
