ObjectivesThe Out-of-Hospital Cardiac Arrest Outcomes (OHCAO) project aims to understand the epidemiology and outcomes of out-of-hospital cardiac arrest (OHCA) across the UK. This data linkage study is a subproject of OHCAO. The aim was to establish the feasibility of linking OHCAO data to National Health Service (NHS) patient demographic data and Office for National Statistics (ONS) date of death data held on the NHS Personal Demographics Service (PDS) database to improve OHCAO demographic data quality and enable analysis of 30-day survival from OHCA.Design and settingData were collected from 1 January 2014 to 31 December 2014 as part of a prospective, observational study of OHCA attended by 10 English NHS Ambulance Services. 28 729 OHCA cases had resuscitation attempted by Emergency Medical Services and were included in the study. Data linkage was carried out using a data linkage service provided by NHS Digital, a national provider of health-related data. To assess data linkage feasibility a random sample of 3120 cases was selected. The sample was securely transferred to NHS Digital to be matched using OHCAO patient demographic data to return previously missing demographic data and provide ONS date of death data.ResultsA total of 2513 (80.5%) OHCAO cases were matched to patients in the NHS PDS database. Using the linkage process, missing demographic data were retrieved for 1636 (72.7%) out of 2249 OHCAO cases that had previously incomplete demographic data. Returned ONS date of death data allowed analysis of 30-day survival status. The results showed a 30-day survival rate of 9.3%, reducing unknown survival status from 46.1% to 8.5%.ConclusionsIn this sample, data linkage between the OHCAO registry and NHS PDS database was shown to be feasible, improving demographic data quality and allowing analysis of 30-day survival status.

ObjectiveTo determine the association between patient and referring practice characteristics and attendance and completion at a specialist health service weight management service (WMS).DesignCross-sectional study.SettingRegional specialist WMS located in the West of Scotland.Participants9677 adults with obesity referred between 2012 and 2014; 3250 attending service and 2252 completing.Primary and secondary outcome measuresPrimary outcome measure was attendance at the WMS; secondary outcome was completion, defined as attending four or more sessions.AnalysisMultilevel binary logistic regression models constructed to determine the association between patient and practice characteristics and attendance and completion.ResultsApproximately one-third of the 9677 obese adults referred attended at least one session (n=3250, 33.6%); only 2252 (23%) completed by attending four or more sessions. Practice referrals ranged from 1 to 257. Patient-level characteristics were strongest predictors of attendance; odds of attendance increased with age (OR 4.14, 95% CI 3.27 to 5.26 for adults aged 65+ compared with those aged 18–24), body mass index (BMI) category (OR 1.83, 95% CI 1.56 to 2.15 for BMI 45+ compared with BMI 30–35) and increasing affluence (OR 1.96, 95% CI 1.17 to 3.28). Practice-level characteristics most strongly associated with attendance were being a non-training practice, having a larger list size and not being located in the most deprived areas.ConclusionsThere was wide variation in referral rates across general practice, suggesting that there is still much to do to improve engagement with weight management by primary care practitioners. The high attrition rate from referral to attendance and from attendance to completion suggests ongoing barriers for patients, particularly those from the most socioeconomically deprived areas. Patient and practice-level characteristics can help us understand the observed variation in attendance at specialist WMS following general practitioner (GP) referral and the underlying explanations for these differences merit further investigation.

IntroductionOsteoarthritis (OA) is a highly prevalent painful condition of the musculoskeletal system. The effectiveness of current analgesic options has proven to be limited and improved analgesic treatment is needed. Several randomised placebo-controlled trials have now demonstrated the efficacy of duloxetine, an antidepressant with a centrally acting effect, in the treatment of OA pain. The aim of the current study is to investigate if duloxetine is effective and cost-effective as a third-choice analgesic added to usual care for treating chronic pain compared with usual care alone in general practice.Methods and analysisA pragmatic open, cluster randomised trial is conducted. Patients with pain due to hip or knee OA on most days of the past 3 months with insufficient benefit of non-steroidal anti-inflammatory drugs or contraindications or intolerable side effects are included. General practices are randomised to either (1) duloxetine and usual care or (2) usual care only. Primary outcome is pain at 3 months measured on the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain subscale. Secondary outcomes at 3 months and 1 year are pain (WOMAC, at 1 year), function (WOMAC), adverse reactions, quality of life and modification of the response to treatment by the presence of centrally sensitised pain (modified PainDETECT). At 1 year, medical and productivity costs will be assessed. Analyses will be performed following the intention-to-treat principle taking the cluster design into account.Ethics and disseminationThe study is approved by the local Medical Ethics Committee (2015–293). Results will be published in a scientific peer-reviewed journal and will be communicated at conferences.Trial registration numberDutch Trial Registry(ntr4798); Pre-results.

Whole-mount in situ hybridization: minimizing the folding problem of thin-sheet tissue-like crayfish haematopoietic tissue
Authors: Zečić Aleksandra , Noonin Chadanat 
Published: November 2017

Crayfish haematopoietic tissue (HPT) has a thin-sheet-like structure with a thickness of 100-160 μm and a width of approximately 1-2 cm. This structure makes HPT extremely easy to fold after removal from the animal. Therefore, it is difficult to handle the tissue without folding when processing for sectioning and histological study. The degree of tissue folding reflects the size of the tissue sections obtained, how complicated it is to interpret the location of each tissue section, and the accuracy of the interpretation of the location of a specific transcript. To facilitate the interpretation of a specific transcript location in the HPT, we optimized a whole-mount in situ hybridization technique to minimize tissue folding. This optimized protocol effectively reduced the tissue folding. Therefore, the location of a specific transcript in the HPT was easily and accurately defined. This protocol will be useful for whole-mount staining of other tissues with similar structure.
Symbiotic Siphonostomatoida (Copepoda) collected from white sharks, Carcharodon carcharias (Lamniformes, Lamnidae), during the OCEARCH expedition along the coast of South Africa
Authors: Dippenaar Susan M. 
Published: November 2017

OCEARCH is a recognized world leader in generating important scientific data about shark species in an attempt to address the globally limited understanding of such species. These species include, amongst others, the IUCN vulnerable white sharks. During the expeditions, sharks are caught, restrained, and supplied with water to assure the flow of oxygen while data are collected within 15 min, whereafter the shark is released unharmed. Within the period from March through May 2012, such an expedition took place along the south and west coasts of South Africa. As part of this expedition copepods were collected from the external surfaces of the captured sharks. They were fixed and preserved in 70% ethanol and examined using microscopes. The copepods recovered represented seven species with the majority of individuals assigned to the Pandaridae and Dichelesthiidae, while only two specimens representing Caligidae.

AbstractA 140-m micrometeorological tower has been operating since August 2016 at 4 km from the coastline and 250 m from a thermal power plant that releases heat from its 20-m stacks in southeastern Brazil. The measurements include 11 levels of turbulence observations and 10 levels of slow-response temperature and humidity. The observed atmospheric structure is largely dependent on the wind direction with respect to the power plant. When winds blow from the plant to the tower, the air layer between 20 and 60 m of the atmosphere may be warmed by as much as 2°C. In these circumstances there are events when the emissions pass directly by the tower. They allow the analysis of turbulence structures of thermal plumes generated from the plant’s heat release in comparison with those generated by the surface heating. In the more common case of winds blowing from the tower to the plant, the observations allow a detailed description of the local atmospheric boundary layer. During the day, vertical profiles of turbulent quantities and their spectral distributions show a cycle controlled by interactions between the land and oceanic surfaces, such as a thermal internal boundary layer. At night, there is a systematic tendency of progressive stabilization throughout the period, suitable for the analysis of the boundary layer transition from weakly to very stable conditions. The data also grant the inference of detailed vertical profiles of turbulent diffusion coefficients directly from observations.

ObjectiveThe purpose is to determine the prevalence of electrocardiogram (ECG) abnormalities, including borderline and prolonged QT, among screened children with sensorineural hearing loss (SNHL) and to analyze their subsequent medical workup.Study DesignInstitutional Review Board–approved case series with chart review.SettingTertiary academic center.Subjects and MethodsCases from 1996 to 2014 involving pediatric patients (N = 1994) with SNHL were analyzed. Abnormal ECGs were categorized as borderline/prolonged QT or other. A board‐certified pediatric cardiologist retrospectively determined the clinical significance of ECG changes. For follow‐up analysis, children with heart disease, known syndromes, or inaccessible records were excluded.ResultsAmong 772 children who had ECGs, 215 (27.8%) had abnormal results: 35 (4.5%) with QT abnormalities and 180 (23.3%) with other abnormalities. For children with QT abnormalities meeting inclusion criteria (n = 30), follow‐up measures included cardiology referral (46.6%), repeat ECG by ear, nose, and throat (ENT) specialist (20%), clearance by ENT specialist with clinical correlation and/or comparison with old ECGs (20%), and pediatrician follow‐up (6.7%). Documentation of further workup by ENT or referral was absent for 6.7%. For children with other ECG changes meeting inclusion criteria (n = 136), abnormalities were documented for 57 (41.9%); normal QT without other abnormality was documented for 18 (13.2%). The most common follow‐up referrals were to pediatricians (16.9%) and cardiologists (10.3%). Among patients with clinically significant non‐QT abnormalities mandating further evaluation (n = 122), 38 (31.1%) had documented follow‐up in medical records.ConclusionThere is a high prevalence of ECG abnormalities among children with congenital SNHL. If findings are confirmed by future studies, screening should be considered for congenital unilateral or bilateral SNHL, regardless of severity. We describe a standardized protocol for ECG screening/follow‐up.

Published: November 2017

Introduction: Medicare beneficiaries often report that the process of choosing a prescription drug plan is frustrating and confusing and many do not enroll in the plan that covers their drugs at the lowest cost. Methods: We conducted 4 focus groups to understand beneficiaries’ experiences in selecting a drug plan to identify what resources and factors were most important to them. Participants were patients served by a multispecialty delivery system and were primarily affluent and Caucasian. Results: While low cost was essential to many, other characteristics like having the same plan as a partner, company reputation, convenience, and anticipation of possible future health problems were sometimes more important. Although some used resources including insurance brokers, counselors, and websites beyond Medicare.gov , many expressed a desire for greater assistance with and greater simplicity in the choice process. Conclusion: Although older adults would likely benefit from greater assistance in choosing Medicare Part D prescription drug plans, more research is necessary to understand how to help with decision-making in this context.
On approximate solutions for a class of semilinear fractional-order differential equations in Banach spaces

Published: November 2017

AbstractWe apply the topological degree theory for condensing maps to study approximation of solutions to a fractional-order semilinear differential equation in a Banach space. We assume that the linear part of the equation is a closed unbounded generator of a$C_{0}$C0-semigroup. We also suppose that the nonlinearity satisfies a regularity condition expressed in terms of the Hausdorff measure of noncompactness. We justify the scheme of semidiscretization of the Cauchy problem for a differential equation of a given type and evaluate the topological index of the solution set. This makes it possible to obtain a result on the approximation of solutions to the problem.
Rock typing in the Upper Devonian-Lower Mississippian Woodford Shale Formation, Oklahoma, USA

Published: November 2017

Most U.S. shale plays are spatially extensive with regions of different thermal maturity and varying production prospects. With increasing understanding of the heterogeneity, microstructure, and anisotropy of shales, efforts are now directed to identifying the sweet spots and optimum completion zones in any shale play. Rock typing is a step in this direction. We have developed an integrated workflow for rock typing using laboratory-petrophysical measurements on core samples and well logs. A total of seven wells with core data were considered for rock typing in the Woodford Shale. The integrated workflow has been applied in the Woodford Shale in a series of steps. In the first step, unsupervised clustering algorithms such as [Formula: see text]-means and self-organizing maps were used to define the rock types. Rock type 1 is generally characterized by high porosity and total organic carbon (TOC). Rock type 2 had intermediate values of porosity and TOC and thus, moderate source potential and storage. Rock type 3 had the highest carbonate content, poor storage, and source rock potential. In the next step, a classification algorithm, support vector machines (SVM), was used to extend the rock types from the cores to the logs. A logging suite with gamma ray, resistivity, neutron porosity, and density logs was used for extending the rock types. These logs were used because they are commonly available and adequate to differentiate different rock types. The rock types were populated in the uncored sections of the seven cored wells and additionally in 12 wells (taken from Drilling Info) using a trained SVM model. Additional wells were taken to have sufficient data for production correlation. In the final step, a rock-type ratio (RTR) was defined based on the fraction of rock type 1 over the gross thickness. RTR was found to positively correlate with normalized oil equivalent production.

Abstract
The objective of this study was to assess the implementation of a three-year Mycobacterium avium subsp. paratuberculosis monitoring programme using pooled faecal culture in small and mediumsized dairy herds to classify them as infected or non-infected and apply proper hygiene and biosecurity measures. Over a three-year period, 35 dairy herds were analysed annually by faecal culture of ten pooled samples. In addition, proper hygiene and biosecurity protocols were implemented in the farms after the first testing round. Considering a herd as infected with at least one culture positive in any of the three years, the accumulated percentage of infected herds was 25.7%, 40% and 45.7%, for each year respectively. Assuming that all infected herds had been detected at the end of the study, the percentage of infected herds detected each year was 56.25% and 87.5% for the first and second year, respectively. Using frequentist and Bayesian approaches, the estimated individual prevalence revealed a downward trend from 3.30-3.65% in the first year to 1.66-1.86% in the third year. The results of this study indicate that pooled faecal culture allowed for proper classification of the herds and can be a useful tool for monitoring dairy herds against paratuberculosis. In addition, statistical analysis of pooled faecal culture results can be used to evaluate the evolution of individual prevalence in the population and therefore the function of the implemented control programmes.

AbstractThe aim of the study was to determine the effect of genotype (breed/line) and spaying of pullets on body weight, estradiol level, carcass and meat quality. Subjects were Rhode Island Red (R-11), Yellowleg Partridge (Ż-33) and Sussex hens (S-66), 100 birds per line, which were divided into 2 groups, each having 50 pullets and 50 poulards. Spaying was performed at 10 wk of age, under local anesthesia by a veterinarian. The present study showed that blood estradiol levels in poulards were much lower than in pullets regardless of genotype. Poulards showed higher body weight and their carcasses higher lightness and yellowness. In the sensory evaluation, poulard breast meat was more tasty and leg meat also more juicy and tender compared to pullet meat. Among the three conserved breeds, Rhode Island Red (R-11) and Yellowleg Partridge (Ż-33) hens are the best starting material for poulard production. Their carcasses showed good muscling and intense yellowness desirable to the consumers. R-11 birds achieved highest body weight. Spaying of pullets had no significant effect on the profile of fatty acids, but greater and statistically significant differences in this regard were found between hen lines. Compared to S-66 birds, breast muscles of R-11 and Ż-33 birds contained more polyunsaturated fatty acids (PUFA). The breast and leg muscles of these birds had a lower content of saturated fatty acids (SFA ).
On the issues related to the discoid cores
Authors: Chen Youcheng , Qu Tongli 
Published: November 2017

AbstractThe discoid core and the Levallois core are important symbols of the Middle Paleolithic Age in the west of the Old World. The two types of artifacts show not only technical relationships but also differences. The discoid core can be classified into two sub-types, namely the unifacial and the bifacial classes. In China, discoid cores may have appeared in the upper Middle Pleistocene, and prevailed in the lower and middle Upper Pleistocene, which corresponded to the middle Paleolithic Age in Europe and to the Middle Stone Age in Africa. The discovery and study of discoid cores provide significant insight into the culture of the Middle Paleolithic Age in China.
The evolution of auspicious beasts in the burial decoration of the Six-Dynasties Period and the formation of the “Jin System”
Authors: Huo Wei 
Published: November 2017

AbstractIn the Six-Dynasties Period, the burial system of China underwent a process of development from the “Han System” to the “Jin System”. Both at ground level and within the underground structures, high-ranking burials of the Six-Dynasties Period all had sculptures or figures of mythical animals meant as guardians or quellers of evil. The motifs and styles of these included not only components inherited from the burials of the Han Dynasty, but also newly emergent cultural elements, and in particular a system of auspicious beasts represented by lions. This new auspicious beast complex was related to the prior “Han System” of burial decoration but also showed clear differences. These changes reflected the symbolic features expressed through the formation of the “Jin System” in another aspect. Their influence reached down to the burial systems of the Tang and Song Dynasties.
