This study quantified the effects of traffic restrictions on diesel fuel heavy vehicles (HVs) on the air quality of the Bandeirantes corridor using hourly data obtained by continuous monitoring of traffic and air quality at sites located on this avenue. The study addressed the air quality of a city impacted by vehicular emissions and that PM10 and NOX concentrations are mainly due to diesel burning. Data collection was split into two time periods, a period of no traffic constraint on HVs (Nov 2008 and 2009) and a period of constraint (Nov 2010, 2011 and 2012)...

Objectives This study aimed to investigate the energy expenditure of common office-based tasks. The objectives were to: (a) test the classification of tasks as sedentary or light-intensity physical activity and (b) compare the energy expenditure of tasks under two postural conditions (sitting and standing). Background The sedentary nature of office work has been highlighted as a health risk, and strategies to reduce sedentary behavior at work have been developed. However, there is limited evidence to guide the utilization of sit-stand workstations in the workplace for metabolic health benefits...

AbstractPodoconiosis, a noninfectious elephantiasis, is a disabling neglected tropical disease. In August 2015, an elephantiasis case-cluster was reported in Kamwenge District, western Uganda. We investigated to identify the disease's nature and risk factors. We defined a suspected podoconiosis case as onset in a Kamwenge resident of bilateral asymmetrical lower limb swelling lasting ≥ 1 month, plus ≥ 1 of the following associated symptoms: skin itching, burning sensation, plantar edema, lymph ooze, prominent skin markings, rigid toes, or mossy papillomata...

Implementing a telephone follow-up system after a patient's emergency department (ED) visit is challenging, but it may improve patient safety and care. This study's objective was to describe the development and implementation of a comprehensive ED telephone follow-up system over a 9-year period. Discharged patients who received a follow-up telephone call within 48 hours of their ED visit included all pediatric patients, those who left without being seen by a provider, and any adult patient with a "high-risk chief complaint," which was defined as a headache, visual problem, chest pain, dyspnea, abdominal pain, syncope, trauma, and neurological-related problems...

BACKGROUND: Burns are a global public health problem. In South Africa, the rate of paediatric burn deaths is 5 times higher than other upper middle-income countries, with concentrations in impoverished settings. Globally, the majority of research focuses on expert and caregiver descriptions of burn occurrence, causation, and prevention, with limited consideration of children's perspectives. This study investigated children's understanding of the causation and prevention of childhood burns...

A neck scar contracture can severely and negatively affect the function of mastication, phonic, or breathing and result in neck pain and issues with esthetics. The best way is of course to avoid such contracture by means of non-surgical treatment such as use of a growth factor. The basic fibroblastic growth factor is clinically well proven in decreasing scar formation and improving healing. There are numerous reconstructive methods for neck contracture, especially when the lesions are relatively limited in part of the neck...

The development of human liver scaffolds retaining their 3-dimensional structure and extra-cellular matrix (ECM) composition is essential for the advancement of liver tissue engineering. We report the design and validation of a new methodology for the rapid and accurate production of human acellular liver tissue cubes (ALTCs) using normal liver tissue unsuitable for transplantation. The application of high shear stress is a key methodological determinant accelerating the process of tissue decellularization while maintaining ECM protein composition, 3D-architecture and physico-chemical properties of the native tissue...

BACKGROUND Infections affecting burn patients are frequently caused by Staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacteriaceae species. Infections with these pathogens have become increasingly difficult to treat due to evolving antibiotic resistance mechanisms, including the production of carbapenemases. CASE REPORT The present case report describes the evolution of a burn patient with polymicrobial healthcare-associated burn infections, including a bloodstream infection due to an emergent multidrug-resistant New Delhi metallo-beta-lactamase (NDM-1)-producing Klebsiella pneumoniae...

DNA sequencing brings another dimension to exploration of biodiversity, and large-scale mitochondrial DNA cytochrome oxidase I barcoding has exposed many potential new cryptic species. Here, we add complete nuclear genome sequencing to DNA barcoding, ecological distribution, natural history, and subtleties of adult color pattern and size to show that a widespread neotropical skipper butterfly known as Udranomia kikkawai (Weeks) comprises three different species in Costa Rica. Full-length barcodes obtained from all three century-old Venezuelan syntypes of U...

Until recently hematopoietic stem cell transplantation was the only curative option for Wiskott-Aldrich syndrome (WAS). The first attempts at gene therapy for WAS using a ϒ-retroviral vector improved immunological parameters substantially but were complicated by acute leukemia as a result of insertional mutagenesis in a high proportion of patients. More recently treatment of children with a state-of-the-art self-inactivating lentiviral vector (LV-w1.6 WASp) has resulted in significant clinical benefit without inducing selection of clones harbouring integrations near oncogenes...

BACKGROUND: Previous work has shown that a ceiling-mounted, 405 nm high-intensity narrow-spectrum light environmental decontamination system (HINS-light EDS) reduces bacterial contamination of environmental surfaces in a burns unit by between 27% and 75%. Examination of the efficacy of the light over extended exposure times and its probable mode of action was performed. AIMS: Studies were designed to ascertain the correlation between bacterial kill achieved on sampled surface sites around the Burns Unit and both irradiance levels of the 405 nm light, and exposure time...

Trauma-induced heterotopic ossification (tHO) is a condition of pathologic wound healing, defined by the progressive formation of ectopic bone in soft tissue following severe burns or trauma. Because previous studies have shown that genetic variants of HO, such as fibrodysplasia ossificans progressiva (FOP), are caused by hyperactivating mutations of the type I bone morphogenetic protein receptor (T1-BMPR) ACVR1/ALK2, studies evaluating therapies for HO have been directed primarily toward drugs for this specific receptor...

Heterotopic ossification (HO), or de novo bone formation in soft tissue, is often observed following traumatic injury. Recent studies suggest that peripheral nerves may play a key functional role in this process. The results supporting a neurological basis for HO are examined in this article. Evidence supports the fact that BMPs released from bone matrix possess the capacity to induce HO. However, the process cannot be recapitulated using recombinant proteins without extremely high doses suggesting other components are required for this process...

BACKGROUND: Epidemiological evidence suggests that developmental vitamin D (DVD) deficiency is a risk factor for neuropsychiatric disorders, such as schizophrenia. DVD deficiency in rats is associated with altered brain structure and adult behaviours indicating alterations in dopamine and glutamate signalling. Developmental alterations in dopamine neurotransmission have also been observed in DVD-deficient rats but a comprehensive assessment of brain neurochemistry has not been undertaken...

BACKGROUND: 90% of the global burden of injuries is borne by low-income and middle-income countries (LMICs). However, details of the injury burden in LMICs are less clear because of the scarcity of data and population-based studies. The Saving of Lives from Drowning project, implemented in rural Bangladesh, did a census on 1·2 million people to fill this gap. This Article describes the epidemiology of fatal and non-fatal injuries from the study. METHODS: In this study, we used data from the baseline census conducted as part of the Saving of Lives from Drowning (SoLiD) project...

BACKGROUND: Anemia of critical illness is resistant to exogenous erythropoietin. Packed red blood cells transfusions is the only treatment option, and despite related cost and morbidity, there is a need for alternate strategies. Erythrocyte development can be divided into erythropoietin-dependent and erythropoietin-independent stages. We have shown previously that erythropoietin-dependent development is intact in burn patients and the erythropoietin-independent early commitment stage, which is regulated by β1/β2-adrenergic mechanisms, is compromised...

Acute akinesia (AA) is an unusual motor complication in Parkinson's disease (PD). Reported risk factors for AA include infection, trauma, surgical intervention, and the withdrawal of antiparkinsonian medication. Recently, patients with genetic PD were reported to have a three-fold risk of AA than patients with non-genetic PD. We describe a patient with PD associated with a Parkin mutation in whom serious akinesia developed. A 42-year-old man with exon 2 heterozygous deletion and exon 4 heterozygous deletion in the PARK2 gene showed five unexpected AA for several 12h...

BACKGROUND: The standard definition for protocol adherence is the proportion of all scheduled doses that are delivered. In clinical research, this definition has several limitations when evaluating protocol adherence in trials that study interventions requiring continuous titration. DISCUSSION: Building upon a specific case study, we analyzed a recent trial of a continuously titrated intervention to assess the impact of different definitions of protocol deviations on the interpretation of protocol adherence...

Recent studies on regional haze pollution over China come up in general with strong variability of main causes of heavy polluted episodes, in linkage with local specificities, sources and pollution characteristics. This paper therefore aims at elucidating the main specific sources and formation mechanisms of observed strong haze pollution episodes over 1-15 November 2015 in Northeast region considered as one of biggest megacity clusters in China. The Northeast China mega-city cluster, including Heilong Jiang, Jilin and Liaoning provinces, is adjacent to Russia in the north, Mongolian at the west, North Korea at east, and representing key geographical location in the regional and transnational air pollution issues in China due to the presence of heavy industries and intense economic activities...
