The objective was to detect Gram-negative bacilli and Gram-positive cocci isolated from the environmental microbiota of the Intensive Care Unit (ICU) departments of Neonatology, Pediatrics, and Transplants (kidney, liver, and general) in a Lima hospital and determine their antimicrobial sensitivity. Eighty samples were obtained from inanimate surfaces using a wet swab. A total of 61 bacterial strains were identified, including Staphylococcus epidermis (46.0%), Alcaligenes sp. (21.3%), Pseudomonas aeruginosa (16...

When considering the numerous events that have prohibited the development of scientific projects or caused destruction of outcrops, it is clear that there is rapidly increasing necessity to define a Brazilian Code of Conduct for geological fieldwork. In general, this destruction is attributed to lack of knowledge as to the relevance of geological sites. The aim of this Code of Conduct is to guide geologists to adopt good practices during geoscience activities. Proposed guidelines are based on Codes of Conduct from other countries, mainly Scotland and England, on situations described in papers and on the personal experience of the authors...

Peel extracts of litchi and rambutan, and that of tamarind seed coat were investigated in relation to their utility in skin-aging treatments. Standardized extracts of tamarind were significantly (p < 0.05) more efficient at O2 •- scavenging (IC50 = 27.44 ± 0.09) than those of litchi and rambutan (IC50 = 29.57 ± 0.30 and 39.49 ± 0.52 μg/ml, respectively) and the quercetin standard (IC50 = 31.88 ± 0.15 μg/ml). Litchi extract proved significantly (p < 0.05) more effective for elastase and collagenase inhibition (88...

INTRODUCTION: Injuries to the gastroesophageal (GE) junction are infrequently encountered because of the high mortality of associated injuries. Consequently, there is a paucity of literature on the patient demographics and treatment options. The aim of this study was to examine the epidemiology, surgical management, and outcomes of these rare injuries. METHODS: Patients presenting to LAC+USC Medical Center (01/2008-08/2016) with traumatic esophageal or gastric injury (ICD-9 and -10 codes) were extracted from the trauma registry...

BACKGROUND: Motorcycle helmet legislation has been a contentious topic for over a half-century. Benefits of helmet use in motorcycle trauma patients are well documented. In 2012, Michigan repealed its universal motorcycle helmet law in favor of a partial helmet law. The authors describe the early clinical effects on facial injuries throughout Michigan. METHODS: Retrospective data from the Michigan Trauma Quality Improvement Program trauma database were evaluated...

BACKGROUND: Thrombosis is a common source of failure in anastomoses, flaps, and vascular grafts. Ensuring vessel patency is critical to the success of microvascular procedures. Any tool that can accurately predict the patency of an anastomosis intraoperatively would enable the surgeon to detect and correct flow restrictions while the patient is still in the operating room. METHODS: The authors used transit-time ultrasound technology in this pilot study to investigate whether a minimal cutoff value for quantitative postoperative blood flow (in milliliters per minute) could be established that would reliably predict sustained vessel patency at 24 hours postoperatively...

Formal faculty development programs for simulation educators are costly and time-consuming. Peer coaching integrated into the teaching flow can enhance an educator's debriefing skills. We provide a practical guide for the who, what, when, where, why, and how of peer coaching for debriefing in simulation-based education. Peer coaching offers advantages such as psychological safety and team building, and it can benefit both the educator who is receiving feedback and the coach who is providing it. A feedback form for effective peer coaching includes the following: (1) psychological safety, (2) framework, (3) method/strategy, (4) content, (5) learner centeredness, (6) co-facilitation, (7) time management, (8) difficult situations, (9) debriefing adjuncts, and (10) individual style and experience...

OBJECTIVES: Skeletal muscle fiber atrophy develops in response to severe sepsis, but it is unclear as to how the proteolytic pathways that are involved in its development are differentially regulated. We investigated the link between sepsis-induced fiber atrophy and activation of the proteasome and autophagy pathways and whether the degree of activation is more severe and sustained in limb muscles than it is in the diaphragm. DESIGN: Randomized controlled experiment...

OBJECTIVE: As the efficacy of a direct antiviral agent is reduced in cirrhotic chronic hepatitis C patients, prolonged duration of treatment or addition of ribavirin is recommended to improve the rates of sustained virological response. However, the impact of cirrhosis on the efficacy of antiviral treatment for chronic hepatitis B (CHB) remained unclear. PATIENTS AND METHODS: This retrospective cohort study screened entecavir (ETV)-treated CHB patients in Taipei Tzu Chi Hospital from January 2007 till October 2014...

CD4(+) T cells differentiate into T helper cell subsets in feedforward manners with synergistic signals from the T cell receptor (TCR), cytokines, and lineage-specific transcription factors. Naive CD4(+) T cells avoid spontaneous engagement of feedforward mechanisms but retain a prepared state. T cells lacking the adaptor molecule LAT demonstrate impaired TCR-induced signals yet cause a spontaneous lymphoproliferative T helper 2 (TH2) cell syndrome in mice. Thus, LAT constitutes an unexplained maintenance cue...

BACKGROUND: In oncology, pain control is a persistent problem. Significant barriers to cancer pain management are patient related. Pain self-management support interventions have shown to reduce pain intensity and patient-related barriers. Comparative effectiveness research is a suitable approach to test whether effects are sustained in clinical practice. OBJECTIVE: In this pilot randomized controlled trial, the implementation of the ANtiPain intervention into clinical practice was tested to assess the effects on pain intensity, function-related outcomes, self-efficacy, and patient-related barriers to pain management to prepare a larger effectiveness trial...

Many studies have suggested that disialogangliosides, GD2 and GD3, are involved in the development of various tumor types. However, the functional relationships between ganglioside expression and cancer development or aggressiveness are not fully described. GD3 is upregulated in approximately half of all invasive ductal breast carcinoma cases, and enhanced expression of GD3 synthase (GD3S, alpha-N-acetylneuraminide alpha-2,8-sialyltransferase) in estrogen receptor-negative breast tumors, was shown to correlate with reduced overall patient survival...

Abemaciclib is an ATP-competitive, reversible kinase inhibitor selective for CDK4 and CDK6 that has shown antitumor activity as a single agent in hormone receptor positive (HR+) metastatic breast cancer in clinical trials. Here, we examined the mechanistic effects of abemaciclib treatment using in vitro and in vivo breast cancer models. Treatment of estrogen receptor positive (ER+) breast cancer cells with abemaciclib alone led to a decrease in phosphorylation of Rb, arrest at G1, and a decrease in cell proliferation...

Patients affected by chronic kidney disease (CKD) exhibit a high risk of cardiovascular mortality that is poorly explained by traditional risk factors. There is a growing awareness about the role of derangement of mineral metabolism that is currently accepted as a trigger and sustainer of cardiovascular disease (CVD) in CKD patients. The synthetic definition of CKD mineral and bone disorder (CKD-MBD) split the concept that the indexes of mineral metabolism extend their effects beyond the bone until the vascular wall and metabolic milieu of CKD patients through complex pathways...

This study compares coal mine tailings management strategies using life cycle assessment (LCA) and land-use area metrics methods. Hybrid methods (the Australian indicator set and the ReCiPe method) were used to assess the environmental impacts of tailings management strategies. Several strategies were considered: belt filter press (OPT 1), tailings paste (OPT 2), thickened tailings (OPT 3), and variations of OPT 1 using combinations of technology improvement and renewable energy sources (OPT 1A-D). Electrical energy was found to contribute more than 90% of the environmental impacts...

This case study reports the results of a 12-year (2005-2016) follow-up study of two Olympic champion rowers. The rowers were prospective athletes at the junior level when the study began, and we monitored their relevant physiological and performance data annually. Our findings indicated that their V̇O2max gradually increased up to about 22 years of age and leveled off at a value of approximately 7 l·min(-1) with minimal fluctuations thereafter. However, the variables that directly influence the V̇O2max changed...

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is characterised by airflow obstruction due to an abnormal inflammatory response of the lungs to noxious particles or gases, for example, cigarette smoke. The pattern of care for people with moderate to very severe COPD often involves regular lengthy hospital admissions, which result in high healthcare costs and an undesirable effect on quality of life. Research over the past decade has focused on innovative methods for developing enabling and assistive technologies that facilitate patient self-management...

Background.: Patients chronically infected with genotype 3 hepatitis C virus (HCV) have faster disease progression and are less responsive to current direct-acting antiviral regimens than patients infected with other genotypes. We conducted an open-label trial to evaluate the safety, tolerability, and efficacy of ledipasvir and sofosbuvir plus ribavirin in patients with genotype 3 HCV infection. Methods.: We enrolled treatment-naive patients with and without compensated cirrhosis at 15 sites in Canada...

Delayed thrombolytic treatment with recombinant tissue plasminogen activator (tPA) may exacerbate blood-brain barrier breakdown after ischaemic stroke and lead to lethal haemorrhagic transformation. The immune system is a dynamic modulator of stroke response, and excessive immune cell accumulation in the cerebral vasculature is associated with compromised integrity of the blood-brain barrier. We previously reported that regulatory T cells, which function to suppress excessive immune responses, ameliorated blood-brain barrier damage after cerebral ischaemia...

Informal caregivers provide the majority of care to persons with dementia; efforts to support caregivers' well-being are increasingly important in the context of limited formal healthcare supports. Informal caregiving is commonly associated with caregiver burden and burden may depend upon patient characteristics including neuropsychological profile, dementia severity, and dementia etiology. This study investigated predictors of caregiver burden in a sample of 213 Memory Clinic patients diagnosed with dementia and whose caregivers provided collateral information...
