The needs and experiences of skin cancer patients: a qualitative systematic review with meta-synthesis

Background: Skin cancer incidence is increasing worldwide. This is an update of a previous review published in 2010 that identified only two studies and found that the needs and experiences of individuals with skin cancer were under-researched. Objectives: To undertake a qualitative systematic review of the needs and experiences of people with a diagnosis of skin cancer. Methods: As an update of a previous review, the following databases were searched from 2010 to 30/11/15: CINAHL PsycINFO, MEDLINE and EMBASE. The methodological quality of the studies was assessed using the Joanna Briggs Institute (JBI) Qualitative Assessment Review Instrument (QARI). The qualitative research findings were synthesised using a pragmatic meta-aggregative approach. Results: Fourteen studies (16 papers) were included. Only three studies included keratinocyte carcinoma patients. 15 categories were identified and these resulted in four overarching synthesised findings (SFs) from diagnosis (SF1) through treatment (SF2) and follow up (SF3), and then a fourth SF (SF4) that addressed patients’ satisfaction with their care and their relationship with health professionals. Conclusions: Despite the fact that keratinocyte carcinoma and melanoma patients can have very different prognosis, they also share similar needs and concerns especially around the time of diagnosis and follow up/surveillance for new lesions. Health professionals working with skin cancer patients need to understand their psychosocial concerns, and their information needs in order to design services appropriately. Future studies need to consider keratinocyte carcinoma patients as well as melanoma patients

Integumentary remains and abdominal contents in the Early Cretaceous Chinese lizard, Yabeinosaurus (Squamata), demonstrate colour banding and a diet including crayfish

The Early Cretaceous lizard Yabeinosaurus is well-represented in the Jehol Biota of northeast China, with specimens yielding information on ontogenetic development, reproductive strategy, and diet, as well as skeletal morphology. However, a large, well-preserved, new specimen of Yabeinosaurus robustus from the Lamadong locality, Liaoning, provides further insights into the morphology and biology of this species. Integumentary traces demonstrate that, in life, Y. robustus was coloured with well-defined light and dark banding through both the body and the tail. The integumentary traces also confirm that Yabeinosaurus was covered with thin, non-overlapping osteoderms. Previous specimens have contained fish remains, suggesting that Yabeinosaurus foraged in, or close, to the water. The new specimen supports that hypothesis as it contains the remains of a large crayfish, identified as belonging to the species Palaeocambarus licenti Taylor et al. 1999. Body parts of the crayfish provide an estimated original total length of 120–140 mm

Genetic testing for Familial Hypercholesterolaemia - Past, Present and Future

In the early 1980s, the Nobel Prize winning cellular and molecular work of Mike Brown and Joe Goldstein led to the identification of the Low Density Lipoprotein Receptor (LDLR) gene as the first gene where mutations cause the Familial Hypercholesterolaemia (FH) phenotype. We now know that autosomal dominant monogenic FH can be caused by pathogenic variants of three additional genes (APOB/PCSK9/APOE), and that the plasma LDL-C concentration and risk of premature Coronary Heart Disease (CHD) differs according to the specific locus and associated molecular cause. It is now possible to use Next Generation Sequencing (NGS) to sequence all exons of all four genes, processing 96 patient samples in one sequencing run, increasing the speed of test results and reducing costs. This has resulted in the identification of many novel FH-causing variants, but also some "Variants of Unknown Significance (VUSs)" which require further evidence to classify as pathogenic or benign. The identification of the FH-causing variant in an index case can be used as an unambiguous and rapid test for other family members. An FH-causing variant can be found in 20%-40% of patients with the FH phenotype, and we now appreciate that in the majority of patients without a monogenic cause, a polygenic aetiology for their phenotype is highly likely. Compared to those with a monogenic cause, these patients have significantly lower risk of future CHD. The use of these molecular genetic diagnostic methods in the characterization of FH is a prime example of the utility of precision or personalised medicine

Self-compassion and physical health: Exploring the roles of perceived stress and health-promoting behaviors

Growing evidence indicates that self-compassion is associated with better physical health, but the pathways that mediate this relationship are not well understood. This study tested a serial mediation model that linked self-compassion, perceived stress, health behaviors, and a comprehensive index of physical health. A sample of 176 individuals completed an online survey posted on Amazon’s Mechanical Turk. Self-compassion had an indirect effect on physical health via both mediators as well as through the sequential pathway, suggesting that taking a kind, accepting and mindful stance toward one’s flaws and failures may have benefits for reducing stress and promoting health behaviors

Not even the past: The joint influence of former leader and new leader during leader successions in the midst of organizational change

Leader succession often occurs during organizational change processes, but the implications of leader succession, in terms of reactions to the change, rarely have been investigated. Employee attitudes and behaviors during organizational change may be influenced jointly by a former leader who recently has transitioned out of the team and the new leader who recently has transitioned into it. We predict an interaction between former and new leaders’ transformational leadership on employees’ behavioral resistance to and support for change. Based on contrast effect theory, a highly transformational former leader constrains the potential effectiveness of the new leader, but a former leader low in transformational leadership enhances this potential effectiveness. We also propose conditional indirect effects transmitted through commitment to the changing organization. Our research was conducted in a large Chinese hospitality organization that was implementing radical organizational change, during which virtually all aspects of processes and products are changed. We collected a 2-wave multisource data from employees who had recently experienced a leader succession and their newly assigned leaders. Based on a final sample of 203 employees from 22 teams, we find empirical support for the proposed interaction effects. The conditional indirect effects were also consistent with our expectations, but the effect on behavioral resistance to change was stronger than the effect on behavioral support for change.postprin

Midazolam-droperidol, droperidol or olanzapine for acute agitation: a randomised clinical trial

STUDY OBJECTIVE: We aim to determine the most efficacious of 3 common medication regimens for the sedation of acutely agitated emergency department (ED) patients. METHODS: We undertook a randomized, controlled, double-blind, triple-dummy, clinical trial in 2 metropolitan EDs between October 2014 and August 2015. Patients aged 18 to 65 years and requiring intravenous medication sedation for acute agitation were enrolled and randomized to an intravenous bolus of midazolam 5 mg-droperidol 5 mg, droperidol 10 mg, or olanzapine 10 mg. Two additional doses were administered, if required: midazolam 5 mg, droperidol 5 mg, or olanzapine 5 mg. The primary outcome was the proportion of patients adequately sedated at 10 minutes. RESULTS: Three hundred forty-nine patients were randomized to the 3 groups. Baseline characteristics were similar across the groups. Ten minutes after the first dose, significantly more patients in the midazolam-droperidol group were adequately sedated compared with the droperidol and olanzapine groups: differences in proportions 25.0% (95% confidence interval [CI] 12.0% to 38.1%) and 25.4% (95% CI 12.7% to 38.3%), respectively. For times to sedation, the differences in medians between the midazolam-droperidol group and the droperidol and olanzapine groups were 6 (95% CI 3 to 8) and 6 (95% CI 3 to 7) minutes, respectively. Patients in the midazolam-droperidol group required fewer additional doses or alternative drugs to achieve adequate sedation. The 3 groups' adverse event rates and lengths of stay did not differ. CONCLUSION: Midazolam-droperidol combination therapy is superior, in the doses studied, to either droperidol or olanzapine monotherapy for intravenous sedation of the acutely agitated ED patient.

A shared framework for the common mental disorders and Non-Communicable Disease: key considerations for disease prevention and control.

BACKGROUND: Historically, the focus of Non Communicable Disease (NCD) prevention and control has been cardiovascular disease (CVD), type 2 diabetes mellitus (T2DM), cancer and chronic respiratory diseases. Collectively, these account for more deaths than any other NCDs. Despite recent calls to include the common mental disorders (CMDs) of depression and anxiety under the NCD umbrella, prevention and control of these CMDs remain largely separate and independent. DISCUSSION: In order to address this gap, we apply a framework recently proposed by the Centers for Disease Control with three overarching objectives: (1) to obtain better scientific information through surveillance, epidemiology, and prevention research; (2) to disseminate this information to appropriate audiences through communication and education; and (3) to translate this information into action through programs, policies, and systems. We conclude that a shared framework of this type is warranted, but also identify opportunities within each objective to advance this agenda and consider the potential benefits of this approach that may exist beyond the health care system

HaloTag is an effective expression and solubilisation fusion partner for a range of fibroblast growth factors.

The production of recombinant proteins such as the fibroblast growth factors (FGFs) is the key to establishing their function in cell communication. The production of recombinant FGFs in E. coli is limited, however, due to expression and solubility problems. HaloTag has been used as a fusion protein to introduce a genetically-encoded means for chemical conjugation of probes. We have expressed 11 FGF proteins with an N-terminal HaloTag, followed by a tobacco etch virus (TEV) protease cleavage site to allow release of the FGF protein. These were purified by heparin-affinity chromatography, and in some instances by further ion-exchange chromatography. It was found that HaloTag did not adversely affect the expression of FGF1 and FGF10, both of which expressed well as soluble proteins. The N-terminal HaloTag fusion was found to enhance the expression and yield of FGF2, FGF3 and FGF7. Moreover, whereas FGF6, FGF8, FGF16, FGF17, FGF20 and FGF22 were only expressed as insoluble proteins, their N-terminal HaloTag fusion counterparts (Halo-FGFs) were soluble, and could be successfully purified. However, cleavage of Halo-FGF6, -FGF8 and -FGF22 with TEV resulted in aggregation of the FGF protein. Measurement of phosphorylation of p42/44 mitogen-activated protein kinase and of cell growth demonstrated that the HaloTag fusion proteins were biologically active. Thus, HaloTag provides a means to enhance the expression of soluble recombinant proteins, in addition to providing a chemical genetics route for covalent tagging of proteins
