Human adenoviruses (HAdVs) are of major public health importance and are associated with a variety of clinical manifestations, including gastroenteritis, respiratory, ocular and urinary tract infections. To study the occurrence, prevalence and diversity of HAdV species and types circulating in Italy, we conducted a large-scale molecular-epidemiological investigation, a yearlong monitoring of 22 wastewater treatment plants, covering 10 Italian regions, representative of northern, central, and southern Italy...

Although numerous cationic lipids have been developed as non-viral gene vectors, the structure-activity relationship (SAR) of these materials remains unclear and needs further investigation. In this work, a series of lysine-derived cationic lipids containing linkages with different rigidity were designed and synthesized. SAR studies showed that lipids with rigid aromatic linkage could promote the formation of tight liposomes and enhance DNA condensation, which is essential for the gene delivery process. These lipids could give much higher transfection efficiency than those containing more flexible aliphatic linkage in various cell lines...

In response to a challenging financial environment and increasing patient demand, St. Michael's Hospital needed to find long-term sustainable solutions to continue to provide high-quality patient care and invest in key priorities. By conducting Operational Reviews in focused areas, the hospital achieved $7.4 million of in-year savings in the first year, found standardizations, process efficiencies and direct cost savings that positioned itself for success in future funding models. Initiatives were grounded in evidence and relied heavily on the effective execution by the leadership, front-line staff and physicians...

Although geared towards a common goal - improved patient-centred care - quality improvement strategies and patient engagement-focused approaches are often developed and conducted in silos. The lack of integration may lead, on the one hand, to the uptake of patient suggestions that do not always take into consideration implications for the delivery of quality care and, on the other hand, to inadequate understanding of patient views required to create optimal services. The Children's Hospital of Eastern Ontario (CHEO)'s action plans to address gaps in patient engagement and quality improvement, two of its priority areas, were initially carried out in isolation of each other...

Discharging patients from the hospital is a complex process, and preventing avoidable readmissions has the potential to improve both the quality of life for patients and the financial sustainability of the healthcare system (Alper et al. 2016). Improving the discharge process is one method to mitigate readmission to the hospital. Historically, St. Thomas Elgin General Hospital (STEGH) consistently experienced higher-than-expected readmission rates, and only 41% of discharge summaries were sent from the hospital to the community primary care within 48 hours...

Evidence suggests that patients with hip fractures should begin rehabilitation no later than six days following surgery. The reality is often far different. In an initiative led by the Greater Toronto Area (GTA) Rehab Network, acute care and rehab/complex continuing care hospitals across the GTA have implemented a new early referral process to aid transition of patients from acute care to inpatient rehabilitation as early as possible to improve their outcomes. Two of the participating acute care hospitals have now surpassed the six-day target and two others are within range...

The presence of vegetation in stream ecosystems is highly dynamic in both space and time. A digital photography technique is developed to map aquatic vegetation cover at species level, which has a very high spatial and a flexible temporal resolution. A digital single-lens reflex (DSLR) camera mounted on a handheld telescopic pole is used. The low-altitude (5 m) orthogonal aerial images have a low spectral resolution (red-green-blue), high spatial resolution (∼1.9 pixels cm(-2), ∼1.3 cm length) and flexible temporal resolution (monthly)...

The visual examination of the vibration patterns of the vocal folds is an essential method to understand the phonation process and diagnose voice disorders. However, a detailed analysis of the phonation based on this technique requires a manual or a semi-automatic segmentation of the glottal area, which is difficult and time consuming. The present work presents a cuasi-automatic framework to accurately segment the glottal area introducing several techniques not explored before in the state of the art. The method takes advantage of the possibility of a minimal user intervention for those cases where the automatic computation fails...

Exogenously applied 2% fructose is the most appropriate carbon source that enhances photosynthesis and growth of grape plantlets compared with the same concentrations of sucrose and glucose. The role of the sugars was regulated by the expression of key candidate genes related to hormones, key metabolic enzymes, and sugar metabolism of grape plantlets ( Vitis vinifera L.) grown in vitro. The addition of sugars including sucrose, glucose, and fructose is known to be very helpful for the development of grape (V...

Despite bovine pericardium (BP) being the primary biomaterial used in heart valve bioprostheses, recipient graft-specific immune responses remain a significant cause of graft failure. Consequently, tissue antigenicity remains the principal barrier for expanding use of such biomaterials in clinical practice. We hypothesize that our understanding of BP antigenicity can be improved by application of a combined affinity chromatography shotgun immunoproteomic approach to identify antigens that have previously been overlooked...

Intensity inhomogeneity is the prime obstacle for MR image processing like automatic segmentation, registration etc. This complication has strong dependence on the associated acquisition hardware and patient anatomy which recommends retrospective correction. In this paper, a new method is developed for correcting the intensity inhomogeneity using a non-iterative multi-scale approach that doesn't necessitate segmentation and any prior knowledge on the scanner or subject. The proposed algorithm extracts bias field at different scales using a Log-Gabor filter bank followed by smoothing operation...

Perception of food consumed is a key factor in acknowledging the need for behavioral change to improve diet quality. We analyzed family dietary intake according to the head of household's perception of satisfaction with food consumed by the family. Households (n = 13,351) that participated in the Brazilian Household Budget Survey and the National Dietary Survey were classified as satisfied or dissatisfied with the food consumed in the home. We compared the family dietary intake of the two groups considering their socio-demographic characteristics...

Patient involvement in healthcare decisions has grown in Brazil at three different levels: 1) the macro level, which includes the patient actively influencing legislation and regulation of medical care as well as political changes in the process of care itself; 2) the meso level, which includes institutions that aim to improve information, empowerment and counseling to patients, and 3) the micro level, which focuses on the actual decision-making process that takes place within patient-physician encounter. In Brazil, the macro and meso levels are stronger than the micro one...

PDZ domains play crucial roles in cell signaling processes and are therefore attractive targets for the development of therapeutic inhibitors. In many cases, C-terminal peptides are the physiological binding partners of PDZ domains. To identify both native ligands and potential inhibitors we have screened arrays synthesized by the process of inverted peptides (PIPE), a variant of SPOT synthesis that generates peptides with free C-termini. Here, we present the development of a new functionalized cellulose membrane as solid support along with the optimized PIPE(PLUS) technology...

Tenascin-C (TnC) is an extracellular matrix glycoprotein implicated in a variety of processes ranging from brain development to synaptic plasticity in the adult vertebrates. Although the role of the TnC gene in regulation of behavior has been investigated, it remained elusive how TnC deficiency interacts with the environment in shaping the behavioral phenotype. To address this, 3-week-old TnC+/+ and TnC-/- male mice were housed over an 8-week period in standard conditions (SC), or enriched environment (EE)...

Chemokine networks regulate a variety of cellular, physiological, and immune processes. These normal functions can become appropriated by cancer cells to facilitate a more hospitable niche for aberrant cells by enhancing growth, proliferation, and metastasis. This is especially true in pancreatic cancer, where chemokine signaling is a vital component in the development of the supportive tumor microenvironment and the signaling between the cancer cells and surrounding stromal cells. Although expression patterns vary among cancer types, the chemokine receptor CXCR4 has been implicated in nearly every major malignancy and plays a prominent role in pancreatic cancer development and progression...

Over the years, the silkworm, Bombyx mori, has been manipulated by means of chemical and genetic approaches to improve silk production both quantitatively and qualitatively. The silk is produced by the silk gland, which degenerates quickly once the larva has finished spinning the cocoon. Thus, interfering with this degeneration process could help develop new technologies aimed at ameliorating silk yield. To this end, in this work we studied the cell death processes that lead to the demise of posterior silk gland of B...

BACKGROUND: Previous research has provided evidence for the link between psychological processes and psychophysiological health outcomes. Psychological interventions, such as face-to-face or online cognitive behavioral therapy (CBT) and serious games aimed at improving health, have shown promising results in promoting health outcomes. Few studies so far, however, have examined whether Internet-based CBT combined with serious gaming elements is effective in modulating health outcomes. Moreover, studies often did not incorporate psychophysiological or immunological challenges in order to gain insight into physiological responses to real-life challenges after psychological interventions...

BACKGROUND: In 2014, nursing home administration and government officials were facing increasing public and media scrutiny around the variation of antipsychotic medication (APM) prescribing across Ontario nursing homes. In response, policy makers partnered to test an academic detailing (AD) intervention to address appropriate prescribing of APM in nursing homes in a cluster-randomized trial. This mixed-methods study aimed to explore how and why the AD intervention may have resulted in changes in the nursing home context...

BACKGROUND: Diabetes shared medical appointments (SMAs) and reciprocal peer support programs have been found in efficacy trials to help adults with diabetes improve their self-management and achieve short-term gains in clinical and patient-centered outcomes. In order to translate this evidence to system-level interventions, there is a need for large-scale, pragmatic trials that examine the effectiveness, implementation, and costs of SMAs and reciprocal peer support across diverse settings...
