Injury and endothelial cell apoptosis are hall marks of atherosclerosis (AS). However, the mechanisms underlying its pathogenesis remain ill-defined. Recent evidence of a role for microRNAs in AS-associated endothelial cell apoptosis encouraged us to address this question. Here, AS was developed in ApoE (-/-) mice supplied with a high-fat diet (HFD), compared to ApoE (-/-) mice supplied with a normal diet (ND). Mouse endothelial cells were isolated from the aortic arch using flow cytometry based on their expression of CD31...

BACKGROUND: Helicobacter valdiviensis is a recently described enterohepatic species isolated from wild bird's fecal samples. Currently, its pathogenic potential and clinical significance are unknown mainly due to the lack of whole-genome sequences to compare with other helicobacters and the absence of specific screenings to determine its prevalence in humans. MATERIALS AND METHODS: The species type strain (WBE14(T) ) was whole-genome-sequenced, and comparative analyses were carried out including the genomes from other Helicobacter species to determine the exact phylogenetic position of H...

BACKGROUND: Leading etiologies of acute illnesses, respiratory viruses typically cause self-limited diseases, though severe complications can occur in fragile patients. Rhinoviruses, respiratory enteroviruses, influenza virus, respiratory syncytial viruses and coronaviruses are highly prevalent respiratory pathogens, but due to the lack of reliable animal models, their differential pathogenesis remains poorly characterized. OBJECTIVE: To compare infections by respiratory viruses isolated from clinical specimens using reconstituted human airway epithelia...

Palliative care demonstrably improves quality of life for the seriously ill in a manner that averts preventable health crises and their associated costs. Because of these outcomes, palliative care is now broadening its reach beyond hospitals, and hospice care for those near death, to patients and their families living in the community with chronic multimorbidities that have uncertain or long expected survival. In this article, we address research needed to enable policies supportive of palliative care access and quality, including changes in regulatory, accreditation, financing, and training approaches in the purview of policy makers...

BACKGROUND: The intensive care unit (ICU) admits critically ill patients requiring advanced airway, respiratory, cardiac and renal support. Despite the highly-specialized interventions, the mortality and morbidity is still high due to a number of reasons including nosocomial infections, which are the most likely complications in hospitalized patients with the rates being highest among ICU patients. METHODS: In this cross-sectional study of 111 adult patients admitted to 2 of the ICUs in Uganda, we set out to describe the commonest bacterial infections, their antimicrobial susceptibility patterns and factors associated with development of a nosocomial infection...

BACKGROUND/AIMS: The injury and apoptotic cell death of endothelial cells hallmark the development of atherosclerosis (AS), characterized by dysregulation of lipid homeostasis, immune responses, and formation of coronary plaques. However, the mechanisms underlying the initiation of endothelial cell apoptosis remain ill-defined. Recent evidence suggests a role of microRNAs in the processes of AS-associated endothelial cell apoptosis. Thus, we studied this question in the current study...

BACKGROUND: Isolated stiffness in a single finger can affect the function of adjacent digits and decrease overall hand function due to the quadriga phenomenon. This study objectively quantifies the dysfunctional impact of each individual stiff finger upon the remaining digits. METHODS: Twenty-five individuals (10 men and 15 women) with a mean age of 31 years (range, 18-58 years) without any upper limb pathology, neuropathy, or systemic illness were recruited. Volar-based finger splints were used to hold individual digits of the dominant hand (24 right and 1 left) sequentially in full extension at the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints...

The human microbiome is an internal ecosystem that refers to the community of microorganisms that populate the human body. These microorganisms are essential to support his health, because the interaction between the host immune system and microorganisms, provide the host with protection against pathogens, and contributes to the preservation of health. Bacteriological culture has been the basis for traditional microbiology; however, most of the bacterial forms observed in nature cannot be isolated with laboratory culture methods...

BACKGROUND: Human Immunodeficiency Virus (HIV) continues to take a heavy toll on the lives of many people, with the worst impact on health and wellbeing for the affected individuals in fragile states. The HIV situation in Somalia is not clearly known and experiences of the people living with HIV in this war-torn region are often unexpressed. This pilot qualitative study sought to explore the experiences of people diagnosed with HIV living in Mogadishu, and their resilience in access to care and social support...

BACKGROUND: Invasive pulmonary aspergillosis (IPA) is an increasingly recognized problem in critically ill patients. Little is known about how intensivists react to a Aspergillus-positive respiratory sample and about the efficacy of antifungals. Our goal was to identify drivers of antifungal therapy (AFT) prescription and diagnostic workup in patients with Aspergillus isolation in respiratory specimens as well as the impact of AFT in these patients. METHODS: ICU patients with a Aspergillus-positive respiratory sample from the database of a previous observational multicenter study were analysed...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

Membrane guanylate cyclase (MGC) is a ubiquitous multi-switching cyclic GMP generating signaling machine linked with countless physiological processes. In mammals it is encoded by seven distinct homologous genes. It is a single transmembrane spanning multi-modular protein; composed of integrated blocks and existing in homo-dimeric form. Its core catalytic domain (CCD) module is a common transduction center where all incoming signals are translated into the production of cyclic GMP, a cellular signal second messenger...

Older lesbians face the triple jeopardy of ageism, sexism, and heterosexism, and their experiences are largely invisible. This qualitative, exploratory study examines the formal and informal caregiving experiences of 20 lesbians, 65 and older, who had utilized home care services due to acute illness or chronic disabilities. Half of those not partnered reported some level of isolation from support networks. Nearly all study participants eventually found home care workers with whom they were satisfied and even quite connected...

The Bacillus cereus group comprises nine species, several of which are pathogenic. Differentiating between isolates that may cause disease and those that do not is a matter of public health and economic importance, but can be particularly challenging due to the high genomic similarity of the group. To this end, we have developed BTyper, a computational tool that employs a combination of (i) virulence gene-based typing, (ii) multi-locus sequence typing (MLST), (iii) panC clade typing, and (iv) rpoB allelic typing to rapidly classify B...

Life expectancy is constantly increasing in the developed countries due to medical, hygiene and socio-economic advances. Unfortunately, a longer life not always corresponds to a healthier life. Indeed, aging is associated with growing risk factors for illness associated with societal conditions (isolation, maltreatment), and neurodegenerative diseases. Even normal aging is associated with a cognitive decline that can hinder independence and quality of life of elderly. Thus, one major societal challenge is to build policies that support people of all ages to maintain a maximum health and functional capacity throughout their lives...

Identification of unknown pathogens in pigs displaying enteric illness is difficult due to the large diversity of bacterial and viral species found within faecal samples. Current methods often require bacterial or viral isolation, or testing only a limited number of known species using quantitative PCR analysis. Herein, faeces from two 25-day-old piglets with diarrhoea from Texas, USA, were analysed by metagenomic next-generation sequencing to rapidly identify possible pathogens. Our analysis included a bioinformatics pipeline of rapid short-read classification and de novo genome assembly which resulted in the identification of a porcine enterovirus G (EV-G), a complete genome with substantial nucleotide differences (>30 %) among current sequences, and a novel non-structural protein similar in sequence to the Torovirus papain-like cysteine protease (PLpro)...

Bacteria within the genus Acinetobacter (principally A. baumannii-calcoaceticus complex [ABC]) are gram-negative coccobacilli that may cause nosocomial infections in critically ill or debilitated patients (particularly ventilator-associated pneumonia and infections of the bloodstream, urinary tract, and wounds). Treatment of Acinetobacter infections is difficult, as Acinetobacter spp. are intrinsically resistant to multiple antimicrobial agents, and have a remarkable ability to acquire new resistance determinants via mechanisms that include plasmids, transposons, integrons, and resistance islands...
