Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

Current clinical practice guidelines recognize EGFR, BRAF, ALK, and ROS1 as essential molecular biomarkers, and a host of other genetic alterations as emerging biomarkers for non-small cell lung carcinoma patients. The available approaches to detecting relevant alterations in these genes are diverse and often complementary. Laboratories have increasingly migrated away from a "single-gene test" approach, embracing assays that incorporate panels of genes capable of detecting a diverse set of alterations...

Lung carcinoma widely affects men and women in the sixth and seventh decades of life. Thorough workup with radiographic imaging, pathologic diagnosis, and cardiopulmonary functional assessment is key to successful treatment. Accurate staging is essential for both assessing prognosis and directing therapy. Early-stage lung cancer is most often treated with anatomic lobectomy; locally advanced cancers may require induction or adjuvant therapies. Any nonnodal metastases will require definitive systemic therapy...

The neuropeptide oxytocin has emerged as a promising pharmacotherapy for methamphetamine (METH) addiction, and clinical trials of intranasal oxytocin are underway. However, there is debate as to how peripherally administered oxytocin alters brain signalling to modulate addiction processes. Interestingly, there is evidence for functional interactions between peripheral oxytocin administration and the vagus nerve. Therefore, this study investigated whether the effects of peripherally administered oxytocin require vagal signalling to reduce METH self-administration and reinstatement of METH-seeking behaviours...

Graphene-based substrates are emerging as a promising functional platform for biomedical applications. Although dispersible graphene sheets have been demonstrated to be biodegradable, their assembled macroscopic architectures are biopersistent because of strong π-π interactions. In this study, we developed a nacre-inspired graphene-silk nanocomposite film by vacuum filtration with a subsequent green chemical reduction procedure. The "brick-and-mortar" architecture not only ensures the mechanical and electrical properties of the film but also endows it with disintegrable and bioresorbable properties following rat subcutaneous implantation...

Problematic Internet Use (PIU) encloses excessive online activities (like video gaming, social media use, web-streaming, pornography viewing, buying). Despite its psychological burden, risk factors related to PIU remain still unclear. In the present study we explored the role of personality traits and emotion dysregulation as potential vulnerability factors for PIU. In a sample of American young adults with different PIU risk levels (established through the Internet Addiction Diagnostic Questionnaire), we administered the Tridimensional Personality Questionnaire (TPQ), the Difficulties in Emotion Regulation Scale (DERS), the Barratt Impulsiveness Scale, the Hamilton Depression Rating Scale, the Hamilton Anxiety Rating Scale...

REVIEW

Estrogen, in the clinical setting is used primarily for contraception and hormone replacement therapy. It has been well established that estrogen increases the risk of both arterial and venous thrombosis. While estrogen is known to induce a prothrombotic milieu through various effects on the hemostatic pathways, the exact molecular mechanism leading to those effects is not known. The most common clinical presentation of estrogen-related thrombosis is venous thromboembolism (VTE) of the deep veins of the legs or pulmonary vessels, usually within the first few months of use...

BACKGROUND: The handover period has been identified as a particularly vulnerable period for communication breakdown leading to patient safety events. Clear and concise handover is especially critical in high-acuity care settings such as trauma, emergency general surgery, and surgical critical care. There is no consensus for the most effective and efficient means of evaluating or performing handover in this population. We aimed to characterize the current handover practices and perceptions in trauma and acute care surgery...

Nutrients recovery has become a meaningful solution to address shortage in the fertilizer production which is the key issue of nations' food security. The concept of municipal wastewater is based on its ability to be a major potential source for recovered nutrients because of its vast quantity and nutrient-rich base. Microbial fuel cell (MFC) has emerged as a sustainable technology, which is able to recover nutrients and simultaneously generate electricity. In this study a two-chambered MFC was constructed, and operated in a continuous flow mode employing artificial municipal wastewater as a substrate...

Resveratrol (RVT) derivatives (10a-i) were designed, synthesized, and evaluated for their potential as gamma-globin inducers in treating Sickle Cell Disease (SCD) symptoms. All compounds were able to release NO at different levels ranging from 0 to 26.3%, while RVT did not demonstrate this effect. In vivo, the antinociceptive effect was characterized using an acetic acid-induced abdominal contortion model. All compounds exhibited different levels of protection, ranging from 5.9 to 37.3%; the compound 10a was the most potent among the series...

An increasing number of peptide drugs have been identified or synthesized in recent decades, and they have played an important role in disease treatments and scientific research. Peptide drugs have become emerging candidates in the pharmaceutical market, despite some inherent disadvantages that have hindered their further development (i.e., they are chemically and physically unstable). Considering that cold-storage conditions are not easily accessible, particularly in developing countries, it remains a significant challenge to find a facile way to enhance the stability of peptide drugs...

Glycogen synthase kinase 3beta (GSK-3β) is an enzyme with a variety of cellular functions in addition to the regulation of glycogen metabolism. In the central nervous system, different intracellular signaling pathways converge on GSK-3β through a cascade of phosphorylation events that ultimately control a broad range of neuronal functions in the development and adulthood. In mice, genetically removing or increasing GSK-3β cause distinct functional and structural neuronal phenotypes and consequently affect cognition...
