(Book) Sprinting towards open publishing: developing strategy and tools to support digital scholarship
Libraries have an emerging role in advocating for and influencing the development of strategy, policy and infrastructure around digital scholarship and open publishing within their institutions. This case study will explore how we have approached this at institutional level by developing a strategic business plan for
University senior management, and also on a practical level by supporting doctoral researchers to carry out a multidisciplinary Book Sprint to publish an open access monograph in four days, providing opportunities to engage with alternative approaches to disseminating scholarly work
Diagnosis and management of malignant peripheral nerve sheath tumors: Current practice and future perspectives
One of the most common malignancies affecting adults with the neurofibromatosis type 1 (NF1) cancer predisposition syndrome is the malignant peripheral nerve sheath tumor (MPNST), a highly aggressive sarcoma that typically develops from benign plexiform neurofibromas. Approximately 8-13% of individuals with NF1 will develop MPNST during young adulthood. There are few therapeutic options, and the vast majority of people with these cancers will die within 5 years of diagnosis. Despite efforts to understand the pathogenesis of these aggressive tumors, the overall prognosis remains dismal. This manuscript will review the current understanding of the cellular and molecular progression of MPNST, diagnostic workup of patients with these tumors, current treatment paradigms, and investigational treatment options. Additionally, we highlight novel areas of preclinical research, which may lead to future clinical trials. In summary, MPNST remains a diagnostic and therapeutic challenge, and future work is needed to develop novel and rational combinational therapy for these tumors
Systematic review of patient-specific pre-operative predictors of pain improvement to endometriosis surgery
BACKGROUND: Up to 28% of endometriosis patients do not get pain relief from therapeutic laparoscopy but this subgroup is not defined. OBJECTIVES: To identify any prognostic patient-specific factors (such as but not limited to patients’ type or location of endometriosis, sociodemographics and lifestyle) associated with a clinically meaningful reduction in post-surgical pain response to operative laparoscopic surgery for endometriosis. SEARCH STRATEGY: PubMed, Cochrane and Embase databases were searched from inception to 19 May 2020 without language restrictions. Backward and forward citation tracking was used. SELECTION CRITERIA, DATA COLLECTION AND ANALYSIS: Cohort studies reporting prognostic factors, along with scores for domains of pain associated with endometriosis before and after surgery, were included. Studies that compared surgeries, or laboratory tests, or outcomes without stratification were excluded. Results were synthesised but variation in study designs and inconsistency of outcome reporting precluded us from doing a meta-analysis. MAIN RESULTS: Five studies were included. Quality assessment using the Newcastle–Ottawa scale graded three studies as high, one as moderate and one as having a low risk of bias. Four of five included studies separately reported that a relationship exists between more severe endometriosis and stronger pain relief from laparoscopic surgery. CONCLUSION: Currently, there are few studies of appropriate quality to answer the research question. We recommend future studies report core outcome sets to enable meta-analysis. LAY SUMMARY: Endometriosis is a painful condition caused by displaced cells from the lining of the womb, causing inflammation and scarring inside the body. It affects 6–10% of women and there is no permanent cure. Medical and laparoscopic surgical treatments are available, but about 28% of patients do not get the hoped-for pain relief after surgery. Currently, there is no way of predicting who gets better and who does not. We systematically searched the world literature to establish who may get better, in order to improve counselling when women choose treatment options. We identified five studies of variable quality showing: More complex disease (in specialist hands) responds better to surgery than less, but more studies needed
Alterations in erythrocyte fatty acid composition in preclinical Alzheimer\u27s disease
Brain and blood fatty acids (FA) are altered in Alzheimer’s disease and cognitively impaired individuals, however, FA alterations in the preclinical phase, prior to cognitive impairment have not been investigated previously. The current study therefore evaluated erythrocyte FA in cognitively normal elderly participants aged 65 – 90 years via trans-methylation followed by gas chromatography. The neocortical beta-amyloid load (NAL) measured via positron emission tomography (PET) using ligand 18F-Florbetaben, was employed to categorise participants as low NAL (standard uptake value ratio; SUVR \u3c 1.35, N = 65) and high NAL or preclinical AD (SUVR ≥ 1.35, N = 35) wherein, linear models were employed to compare FA compositions between the two groups. Increased arachidonic acid (AA, p \u3c 0.05) and decreased docosapentaenoic acid (DPA, p \u3c 0.05) were observed in high NAL. To differentiate low from high NAL, the area under the curve (AUC) generated from a ‘base model’ comprising age, gender, APOEε4 and education (AUC = 0.794) was outperformed by base model + AA:DPA (AUC = 0.836). Our findings suggest that specific alterations in erythrocyte FA composition occur very early in the disease pathogenic trajectory, prior to cognitive impairment. As erythrocyte FA levels are reflective of tissue FA, these alterations may provide insight into the pathogenic mechanism(s) of the disease and may highlight potential early diagnostic markers and therapeutic targets
Safety and pharmacokinetics of multiple dose myo-inositol in preterm infants
BACKGROUND:
Preterm infants with respiratory distress syndrome (RDS) given inositol had reduced bronchopulmonary dysplasia (BPD), death and severe retinopathy of prematurity (ROP). We assessed the safety and pharmacokinetics of daily inositol to select a dose providing serum levels previously associated with benefit, and to learn if accumulation occurred when administered throughout the normal period of retinal vascularization.
METHODS:
Infants ≤ 29 wk GA (n = 122, 14 centers) were randomized and treated with placebo or inositol at 10, 40, or 80 mg/kg/d. Intravenous administration converted to enteral when feedings were established, and continued to the first of 10 wk, 34 wk postmenstrual age (PMA) or discharge. Serum collection employed a sparse sampling population pharmacokinetics design. Inositol urine losses and feeding intakes were measured. Safety was prospectively monitored.
RESULTS:
At 80 mg/kg/d mean serum levels reached 140 mg/l, similar to Hallman's findings. Levels declined after 2 wk, converging in all groups by 6 wk. Analyses showed a mean volume of distribution 0.657 l/kg, clearance 0.058 l/kg/h, and half-life 7.90 h. Adverse events and comorbidities were fewer in the inositol groups, but not significantly so.
CONCLUSION:
Multiple dose inositol at 80 mg/kg/d was not associated with increased adverse events, achieves previously effective serum levels, and is appropriate for investigation in a phase III trial
Blood myo-inositol concentrations in preterm and term infants
Objective: To describe relationship between cord blood (representing fetal) myo-inositol concentrations and gestational age (GA) and to determine trends of blood concentrations in enterally and parenterally fed infants from birth to 70 days of age.
Design/methods: Samples were collected in 281 fed or unfed infants born in 2005 and 2006. Myo-inositol concentrations were displayed in scatter plots and analyzed with linear regression models of natural log-transformed values.
Results: In 441 samples obtained from 281 infants, myo-inositol concentrations varied from nondetectable to 1494 μmol/L. Cord myo-inositol concentrations decreased an estimated 11.9% per week increase in GA. Postnatal myo-inositol concentrations decreased an estimated 14.3% per week increase in postmenstrual age (PMA) and were higher for enterally fed infants compared to unfed infants (51% increase for fed vs. unfed infants).
Conclusions: Fetal myo-inositol concentrations decreased with increasing GA. Postnatal concentrations decreased with increasing PMA and were higher among enterally fed than unfed infants
Impact of Optimized Breastfeeding on the Costs of Necrotizing Enterocolitis in Extremely Low Birthweight Infants
To estimate risk of NEC for ELBW infants as a function of preterm formula and maternal milk (MM) intake and calculate the impact of suboptimal feeding on NEC incidence and costs
Everyday Life on Planet Jedward: Thinking of John and Edward Grimes. On Everyday Life as a Jedward fan.
Identical twins John and Edward Grimes (artist name "Jedward") have been active for six years and have a heterogeneous following of fans. This thesis aims to investigate how and in which situations fans think about Jedward as part of their everyday life. Each of the three informants, plus the author, kept diaries recording the above for the course of one week. The diaries were subsequently coded into the groups Traditional Fandom, Social Media, Music, Places, Family & Friends, Interests & Hobbies, Studies, Film & TV and Food & Drink respectively. Auto-ethnographic method was implemented and combined with work within the spheres of fandom and music. At a later date informants were asked if there are any products or causes that they associate with John and Edward; in lieu of comprehensive answers, the author compiled such a list. For the fours fans taking part, John and Edward are experienced as being close to them in many different situations during their day-to-day lives, in much the same way as a close friend or loved one. The conclusion is that through aiming to portray my own interpretation of fandom, it has been possible to see just how creative and imaginative fans are, an enlightening reflection contrary to those which in many cases have been none too positive
Living Life on Planet Jedward: The Genius of John and Edward Grimes : On Jedward. And Fandom.
John and Edward Grimes (artist name "Jedward") have been active for four and a half years and have a heterogeneous following of fans. This thesis aims to investigate how and why people become Jedward fans, how they view the fandom and what experiences they have of being round the twins. After respondents, independently of one another, began disclosing how the twins and fandom had fundamentally changed their lives, this area of investigation was also pursued. The conclusion is that while there are some negative aspects of fandom, for those taking part in the study, being a fan of Jedward has led to what I've chosen to term "Fandom-Induced Self-Efficacy"
