Magazine Culture, Girlhood Communities, and Educational Reform in Late Victorian Britain
Authors: Gleadle Kathryn 
Published: September 2019

Abstract
This will appear online only.This article argues for the importance of restoring girls’ aspirations and self-education to narratives of Victorian educational reform. Studies typically focus upon the efforts of professionals, politicians and campaigners in plotting the pioneering changes to girls’ education in the second half of the nineteenth century. Here it is contended that the success of these developments depended upon a new generation of girls with the confidence and ambition to take advantage of the new opportunities to sit examinations and attend university. To do this, the article excavates the neglected phenomenon of the manuscript magazine. It examines how young females used well-established periodicals to advertise their own amateur magazines. Inviting readers to contribute to their ventures, they constructed independent networks of collaborative cultural endeavour. Manuscript magazines, it will be suggested, need to be understood as part of a ‘magazine culture’ widely embraced by Victorian girls. To tease out the small but subtle ways in which magazine culture could enhance the aspirations of young women, the article focuses upon the extraordinary diary archives of Eva Knatchbull-Hugessen (1861–95). The educational career of Knatchbull-Hugessen, who was an early student at Newnham College in the 1880s, exemplifies the impact which engagement in girlhood culture could engender and the significant role played by magazines, both professional and amateur, in this process. Understanding teenage responses to educational reforms requires a recalibration of our analytical lens to focus not upon grand narratives of feminist awakening but rather upon the small subjective shifts which typically underlay young females’ decisions.
Efficiency in Decentralised Markets with Aggregate Uncertainty
Authors: Camargo Braz , Gerardi Dino , Maestri Lucas 
Published: September 2019

Abstract
We study efficiency in non-stationary decentralised markets with common-value uncertainty and correlated asset values. There is an equal mass of buyers and sellers and payoffs from trade depend on an aggregate state, which only the sellers know. Buyers and sellers are randomly and anonymously matched in pairs over time, and buyers make the offers. We show that all equilibria become efficient as trading frictions vanish.
Joining up optimisation of wood supply chains with forest management: a case study of North Karelia in Finland

Published: September 2019

AbstractThis paper presents a spatially explicit methodology for integrated forest management and wood supply chain optimization over time in the context of a Finnish forest strategy anticipating new investments and renewal of business in the wood processing industry. The Finnish MELA simulator was used to generate multiple treatment schedules over time at the management unit level – each treatment schedule providing unique estimates of extracted wood volumes by different assortment categories for each time period. The J linear programming (LP) software was used to analyse different regional forest strategies in terms of wood supply and transportation costs to multiple market destinations. The analysis revealed clear differences both in wood flows and forest resources between strategies maximizing wood supply or optimizing wood supply to market destinations. In addition, the wood flows appeared responsive to new mill and increased demand. Further, the changes in factory price had a heavier impact on pulpwood supply than on sawlog supply. The same methodology can be applied for analysing the impact of new factories on wood flows from forest to factories and between factories or to support forest enterprises in planning their wood supply over multiple time periods and multiple destinations.

Abstract

Background and Objectives
Though subjective age is a well-recognized risk factor for several chronic diseases, the biological basis for these associations remains poorly understood.

Research Design and Methods
We used new comprehensive biomarker data from the 2016 wave of the nationally representative Health and Retirement Study (HRS) to evaluate the association between biomarker levels and self-reported subjective age in a subset of 3,740 HRS participants who provided a blood sample. We measured biomarkers in seven biological domains associated with aging: inflammation, glycemia, lipids, liver function, endocrine function, renal function, and cardiac function. The primary outcome was the age discrepancy score (subjective age − chronological age) categorized as those who felt younger, older, or the same as their chronological age (reference group). Analyses adjusted for comprehensive psychosocial factors (chronic stress index, depression score), demographic factors (race, sex, body mass index, marital status, physical activity), and prevalence of chronic health conditions (comorbidity index).

Results
The prevalence of clinically relevant reduced levels of albumin concentrations was lower in those who felt younger (8.8% vs. 16.0%; p = .006) and higher in those who felt older (20.4% vs. 16.0%; p = .03) when compared with the reference category. The prevalence of clinically significant elevation in liver enzymes such as alanine aminotransferase was also significantly lower among those who felt younger (7.1% vs. 8.6%; p = .04) when compared with the reference category. Prevalence of clinically elevated levels in cystatin C was also lower among those who felt younger when compared with the reference category (50.0% vs. 59.1%; p = .04). There was no association between lipids, glucose, or C-reactive protein (inflammatory marker) and subjective age categories.

Discussion and Implications
These results suggest that people who feel younger may have favorable biomarker profiles and as a result may have lower prevalence of age-related diseases when compared with those who feel older or those who feel the same as their chronological age.

Published: September 2019

Abstract
The direction and nature of incisions can impact the healing and appearance of a surgical scar. This can be attributed mainly due to skin tension and direction of force. The aim of this study was to identify differences in healing rates and scar esthetics between transverse and longitudinal portals used for hip arthroscopy. A total of 75 patients underwent bilateral hip arthroscopy for femoroacetabular impingement. All patients received a portal perpendicular to the long axis of the body on the left side (transverse portal) and parallel with the long axis of the body on the right side (longitudinal portal) for the standard anterolateral viewing portal. Postoperatively, patients were reviewed at 2 weeks, 6 weeks, 3 months and 6 months and the portal scars were assessed, photographed and measured. No patients were lost to follow-up. The transverse scars, although slightly longer, were found to be narrower at 6 weeks (3.8 mm versus 2.7 mm, P < 0.01), 3 months (4.3 mm versus 3.4 mm, P = 0.01) and 6 months postoperatively (6.1 mm versus 4.5 mm, P < 0.01). At 3 months (43 mm2 versus 35 mm2, P = 0.029) and 6 months (49 mm2 versus 43 mm2, P = 0.024), transverse incisions were noted to have significantly reduced total area compared with longitudinal incisions. There were no wound complications in either group. This study demonstrates that transverse portal positions for hip arthroscopy have an advantage over longitudinal portal positions in terms of total scar area and thickness up to 6 months postoperatively.

Published: September 2019

Abstract

Background
Previous cognitive behavioral therapies for informal caregivers (ICs) have produced negligible effects. The purpose of this study was to evaluate, in a randomized controlled trial, the efficacy of Emotion Regulation Therapy adapted for caregivers (ERT-C) on psychological and inflammatory outcomes in psychologically distressed ICs and the cancer patients cared for.

Methods
A total of 81 ICs with elevated psychological distress were randomly assigned to ERT-C or a waitlist condition and assessed pre-, mid-, and post-treatment. In 52 cases, the patient cared for by the IC was included. Patients did not receive ERT-C. Both the ERT-C and waitlist groups were followed 3 and 6 months post-treatment. Data were analyzed with multilevel models, and P values were two-sided.

Results
Compared with ICs in the waitlist condition, ICs in the ERT-C condition experienced medium to large statistically significant reductions in psychological distress (Hedge’s g = 0.86, 95% confidence interval [CI] = 0.40 to 1.32, P &lt; .001), worry (g = 0.96, 95% CI = 0.50 to 1.42, P &lt; .001), and caregiver burden (g = 0.53, 95% CI = 0.10 to 1.99, P = .007) post-treatment. No statistically significant effects were found for rumination (g = 0.24, 95% CI = −0.20 to 0.68, P = .220). Results concerning caregiver burden were maintained through 6 months follow-up. Although the effects on psychological distress and worry diminished, their end-point effects remained medium to large. No statistically significant effects on systemic inflammation were detected (C-reactive protein: g = .17, 95% CI = −0.27 to 0.61, P = .570; interleukin-6: g = .35, 95% CI = −0.09 to 0.79, P = .205; tumor necrosis factor-alpha: g = .11, 95% CI = −0.33 to 0.55, P = .686). Patients whose ICs attended ERT-C experienced a large increase in quality of life post-treatment (g = 0.88, 95% CI = 0.18 to 1.58, P = .017).

Conclusions
To our knowledge, this is the first randomized controlled trial evaluating the efficacy of ERT-C for ICs. Given the previous disappointing effects of other cognitive behavioral therapies for this population, the present findings are very encouraging. Identifying ICs with elevated psychological distress and providing them with relevant psychotherapy appears an important element of comprehensive cancer care.
2D-Galactic chemical evolution: the role of the spiral density wave

Published: September 2019

ABSTRACT
We present a 2D chemical evolution code applied to a Milky Way type Galaxy, incorporating the role of spiral arms in shaping azimuthal abundance variations, and confront the predicted behaviour with recent observations taken with integral field units. To the usual radial distribution of mass, we add the surface density of the spiral wave and study its effect on star formation and elemental abundances. We compute five different models: one with azimuthal symmetry which depends only on radius, while the other four are subjected to the effect of a spiral density wave. At early times, the imprint of the spiral density wave is carried by both the stellar and star formation surface densities; conversely, the elemental abundance pattern is less affected. At later epochs, however, differences among the models are diluted, becoming almost indistinguishable given current observational uncertainties. At the present time, the largest differences appear in the star formation rate and/or in the outer disc (R ≥ 18 kpc). The predicted azimuthal oxygen abundance patterns for t ≤ 2 Gyr are in reasonable agreement with recent observations obtained with VLT/MUSE for NGC 6754.

ABSTRACT
We present a Bayesian full-spectral-fitting analysis of 75 massive ($M_* \gt 10^{10.3} \, \mathrm{M_\odot }$) UVJ-selected galaxies at redshifts of 1.0 &lt; z &lt; 1.3, combining extremely deep rest-frame ultraviolet spectroscopy from VANDELS with multiwavelength photometry. By the use of a sophisticated physical plus systematic uncertainties model, constructed within the bagpipes code, we place strong constraints on the star-formation histories (SFHs) of individual objects. We first constrain the stellar mass versus stellar age relationship, finding a steep trend towards earlier average formation time with increasing stellar mass (downsizing) of $1.48^{+0.34}_{-0.39}$ Gyr per decade in mass, although this shows signs of flattening at $M_* \gt 10^{11} \, \mathrm{M_\odot }$. We show that this is consistent with other spectroscopic studies from 0 &lt; z &lt; 2. This relationship places strong constraints on the AGN-feedback models used in cosmological simulations. We demonstrate that, although the relationships predicted by simba and illustristng agree well with observations at z = 0.1, they are too shallow at z = 1, predicting an evolution of ≲0.5 Gyr per decade in mass. Secondly, we consider the connections between green-valley, post-starburst, and quiescent galaxies, using our inferred SFH shapes and the distributions of galaxy physical properties on the UVJ diagram. The majority of our lowest-mass galaxies ($M_* \sim 10^{10.5} \, \mathrm{M_\odot }$) are consistent with formation in recent (z &lt; 2), intense starburst events, with time-scales of ≲500 Myr. A second class of objects experience extended star-formation epochs before rapidly quenching, passing through both green-valley and post-starburst phases. The most massive galaxies in our sample are extreme systems: already old by z = 1, they formed at z ∼ 5 and quenched by z = 3. However, we find evidence for their continued evolution through both AGN and rejuvenated star-formation activity.
Revealing the galaxy–halo connection in IllustrisTNG

Published: September 2019

ABSTRACT
We use the IllustrisTNG (TNG) simulations to explore the galaxy–halo connection as inferred from state-of-the-art cosmological, magnetohydrodynamical simulations. With the high-mass resolution and large volume achieved by combining the 100 Mpc (TNG100) and 300 Mpc (TNG300) volumes, we establish the mean occupancy of central and satellite galaxies and their dependence on the properties of the dark matter haloes hosting them. We derive best-fitting HOD parameters from TNG100 and TNG300 for target galaxy number densities of $\bar{n}_g = 0.032\,$  and $\bar{n}_g = 0.016\, h^3$ Mpc−3, respectively, corresponding to a minimum galaxy stellar mass of $M_\star \sim 1.9\times 10^9\, $ and $M_\star \sim 3.5\times 10^9\, {\rm M}_\odot$, respectively, in hosts more massive than $10^{11}\, {\rm M}_\odot$. Consistent with previous work, we find that haloes located in dense environments, with low concentrations, later formation times, and high angular momenta are richest in their satellite population. At low mass, highly concentrated haloes and those located in overdense regions are more likely to contain a central galaxy. The degree of environmental dependence is sensitive to the definition adopted for the physical boundary of the host halo. We examine the extent to which correlations between galaxy occupancy and halo properties are independent and demonstrate that HODs predicted by halo mass and present-day concentration capture the qualitative dependence on the remaining halo properties. At fixed halo mass, concentration is a strong predictor of the stellar mass of the central galaxy, which may play a defining role in the fate of the satellite population. The radial distribution of satellite galaxies, which exhibits a universal form across a wide range of host halo mass, is described accurately by the best-fitting NFW density profile of their host haloes.

Published: September 2019

Abstract
There is inadequate neurosurgical literature discussing appropriate clinical study design. Here, we explore considerations for 2 fundamental study designs of epidemiology: experimental and observational cohort studies, through examples of theoretical yet realistic neurosurgical research questions. By examining 2 common neurosurgical procedures—namely, subdural drains for evacuation of chronic subdural hematoma, and the utility of navigation for placing external ventricular drains—we characterize the framework of cohort study models for clinical research applications.
Provider-reported challenges and barriers to referring patients to neuro-oncology clinical trials: a report from the Society for Neuro-Oncology member survey
Authors: Rogers James L , Acquaye Alvina , Vera Elizabeth , Bates Amanda , Wen Patrick Y , Armstrong Terri S 
Published: September 2019

Abstract

Background
Whereas much information exists in general oncology regarding the barriers to clinical trial referral, those specific to neuro-oncology are not yet well known. Trial barriers lead to lower patient accrual, which can lead to less-efficient clinical trials and slower improvement of the standard of care, which may negatively effect patient outcomes. Thus, the aim of this study was to determine the clinical trial referral barriers that are specific to neuro-oncology to improve trial accrual rates.

Methods
An electronic survey was completed by 426 Society for Neuro-Oncology members, of whom 372 are included in this report. Descriptive statistics, including frequencies, means, and proportions, were used to characterize our survey sample.

Results
Only 22% of participants reported that their center tracks referrals to clinical trials inside as well as outside their own institution, with an estimate of less than 30% of patients referred. The most commonly reported provider-referral barrier was finding ongoing trials in the patient’s geographic area. Providers also perceived that while considering participation in a trial their patients may not qualify for any trials, and if they do, may be unable to travel to the study site for follow-up. Additionally, practice location and provider and institution type all influenced referral patterns.

Conclusion
Efforts should be made to broaden trial availability and eligibility criteria, improve trial referral tracking, and ensure patients and their caregivers understand the goals and importance of clinical trials to reduce barriers and improve trial participation.

Published: September 2019

Abstract

Objectives
Timely treatment of patients with Early Rheumatoid Arthritis (ERA) favors a beneficial disease outcome. However, individuals often delay their contact with a healthcare professional (HCP) after ERA-related symptom onset. This study investigates the patients’ perspective on the patient’s journey from RA symptom onset until referral to a specialist.

Methods
A subgroup of patients with ERA from the Care in ERA (CareRA) trial were retrospectively interviewed to discuss their initial ERA-related experiences preceding diagnosis, using a bespoke assessment form. The form’s first section focused on initial symptoms and patients’ help-seeking behavior. The second part probed the consulted HCPs’ actions. Additional notes derived from the patient stories were thematically analyzed.

Results
Among 94 patients, pain (97%), swelling (73%) and stiffness (52%), typically in multiple joints, were reported as initial ERA-symptoms. The general practitioner (GP) was generally the first contacted HCP (87%). Frequently reported reasons to visit a HCP were too intense pain (90.4%) and difficulties in performing daily activities (69%). In 44.1% of patients, the HCP suspected ERA at the first visit. Approximately 25% of patients needed >5 visits before ERA detection. GPs mainly referred patients to rheumatologists (71%). Thematic analysis uncovered that often multiple HCPs were involved in the journey to RA detection and referral.

Conclusion
Pain is the most commonly reported initial symptom of ERA and the main reason to visit a HCP, mostly a GP. These GPs play a pivotal role in early detection and correct referral. Furthermore, the patient’s journey seems complex with often multiple HCPs involved.
Procedural sedation in ambulatory anaesthesia: what's new?
Authors: Raeder Johan 
Published: September 2019

Purpose of review
Although sedation traditionally has been regarded as an easy, straight forward and simple variety of general anaesthesia; the trends are to make sedation more sophisticated and dedicated. Also to have a critical look at old dogmas, as they are usually derived from the practice of general anaesthesia. Safety always has to be first priority, especially as the practice grows out of traditional theatres and frequently are being practiced by nonanaesthetic personnel.

Recent findings
Safety comes from learning of rare cases with severe problems as well as better guidelines and rules of accreditation. Further, there is a growing quest for evidence on pragmatic, high-quality, cost-effective practice; in terms of logistics, monitoring, choice of drugs and quality assurance. The traditional drugs, such as propofol, midazolam and remifentanil, are still defending their dominant position but are being challenged by ketamine and etomidate. Remimazolam and dexmedetomidine are new promising drugs in this area, whereas metoxyflurane may have a revival in some situations. Further, there is growing evidence into specific protocols, practice for special procedures and for patients with special challenges.

Summary
Procedural sedation deserves to have high degree of attention for further developments, both from a scientific and pragmatic point of view, as the practice is very diversified and growing.
Proper Surgical Dressing Removal Technique in Obstetrics and Gynecology
Authors: Cherry Steven B. , Vasko Michelle 
Published: September 2019

BACKGROUND:
Medical adhesive–related skin injury is often caused by improper technique in removing surgical dressings and may lead to pain, infection, delayed healing, and litigation. It is rare for obstetrics and gynecology residents and staff to receive any training regarding the proper technique for removing surgical dressings.

TECHNIQUE:
The proper technique for the removal of adhesive dressings is discussed, minimizing patient discomfort and lessening the risk of skin injury. A video is included.

EXPERIENCE:
By using a slow rate of removal, the proper angle of traction, counter-traction with an index finger, and adhesive solvents when necessary, patients experience much less pain with dressing removal, and skin injury can be avoided.

CONCLUSION:
Using proper technique when removing adhesive dressings can reduce the incidence of skin injury. Obstetrician–gynecologists should be cognizant of the risk of iatrogenic medical adhesive–related skin injury.
