Importance, Errors, and Patterns of Quotations to Psychiatric
Original Articles
Authors: Baethge Christopher 
Published: June 2020

Abstract
Introduction A substantial rate of quotation errors has been reported in
medical journal publications: about 25% of all quotations are wrong. It
is, however, entirely unclear how important quotation errors are for the message
of quoting articles.
Methods This is a case study in form of a retrospective quotation analysis
of a cohort of 72 psychiatric original articles (index articles) from 5
German-language general psychiatric journals. Main outcomes were importance and
accuracy of quotations from the 2 calendar years following the publication of
index articles.
Results Fifty-one index articles were quoted 235 times in 109 quoting
articles. Almost all quotations were of medium (76% [95% CI:
70%; 81%]) or high (20% [15%, 25%])
importance for the message of the quoting paper. Regarding quotation accuracy,
44 quotations (19% [14%; 24%]) were rated as minor, and
51 (22% [17%; 27%]) as major errors. In multivariable
analyses, no statistically significant and practically relevant factors
associated with quotation inaccuracy emerged, such as self-quotation, impact
factor of the quoting journal, or importance. Among quoting articles, 7
(6% [3%; 13%]) showed a pattern of predominantly quoting
index articles from the time span relevant to the calculation of the impact
factor.
Discussion Quotations are important for the message of the quoting paper.
Therefore, quotation errors may be detrimental to scientific reasoning and may
undermine public trust in medical science. The present investigation is a case
study, and its results are exploratory. While it is plausible that the findings
translate into other environments, independent replication is needed.

Abstract
Objective To assess maternal and perinatal outcomes of pregnancies in women with chronic hypertension (CH).
Methods Retrospective cohort of women with CH followed at a referral center for a 5 year period (2012–2017). Data were obtained from medical charts review and described as means and frequencies, and a Poisson regression was performed to identify factors independently associated to the occurrence of superimposed pre-eclampsia (sPE).
Results A total of 385 women were included in the present study; the majority were > than 30 years old, multiparous, mostly white and obese before pregnancy. One third had pre-eclampsia (PE) in a previous pregnancy and 17% of them had organ damage associated with hypertension, mainly kidney dysfunction. A total of 85% of the patients used aspirin and calcium carbonate for pre-eclampsia prophylaxis and our frequency of sPE was 40%, with an early onset (32.98 ± 6.14 weeks). Of those, 40% had severe features of PE, including 5 cases of HELLP syndrome; however, no cases of eclampsia or maternal death were reported. C-section incidence was high, gestational age at birth was 36 weeks, and nearly a third (115 cases) of newborns had complications at birth One third of the women remained using antihypertensive drugs after pregnancy.
Conclusion Chronic hypertension is related with the high occurrence of PE, C-sections, prematurity and neonatal complications. Close surveillance and multidisciplinary care are important for early diagnosis of complications.

Abstract
Objective Desmoplastic small round cell tumor (DSRCT) is a rare intraabdominal neoplasm that grows along serosal surfaces and is primarily found in young men. To date, only 16 cases of ovarian DSRCT have been previously reported in women in the English literature, and no large population-based studies on this topic exist.
Case Report We report the case of a 19-year-old virgo with unremarkable past medical history, initially presented with abdominal fullness. After being treated with the optimal treatment modality (primary and secondary surgical debulking, unique chemotherapy, protocol and adjuvant radiotherapy), the patient has remained without tumor disease for 40 months.
Conclusion Although the best therapy for patients with DSRCT has yet to be determined, combining complete surgical resection, adjuvant chemotherapy, and radiotherapy is required to prolong survival and to achieve proper quality of life.

AbstractBecause of the early follow-up positive outcomes with cementless fixation, continued evaluations need to be performed to ensure longer-term efficacy. Additionally, although many studies report on the results of femoral and tibial component fixation, few studies report specifically on patellar outcomes. Therefore, the purpose of this study was to report on the: (1) implant survivorship; (2) complications; and (3) radiographic outcomes in a large cohort of patients who received cementless total knee arthroplasties (TKAs), with particular attention to the patellar component. A total of 261 patients who underwent cementless TKA by a single, high-volume academic surgeon were studied. Patients had a mean age of 66 years and were distributed between 192 women (74%) and 69 men. All patients received the same cementless tibial, femoral, and patellar components. Mean follow-up period was 4.5 years (range, 4–5 years). Primary outcomes evaluated included all postoperative complications, with particular emphasis on the patellar component. Only one patellar loosened leading to a patellar aseptic loosening rate of 0.3% (1 of 261). The one patellar loosening was the component being dislodged after a manipulation under anesthesia (MUA) at 6 weeks. This was revised to a cemented component and the patient is doing well 4 years later. A second patient experienced a patellar tendon rupture, later surgically repaired. Another patient sustained a patella fracture that was managed nonoperatively. The fracture healed by 1 year and the patient continued to have an otherwise successful outcome, now at 2 years follow-up. No progressive radiolucencies, subsidence, or changes in initial postoperative axial alignment were observed at final follow-up. The results from this study highlight a 98% success rate at mean 4.5 years follow-up in a large cohort of patients with a diverse spread of demographic details. Specific to the patella, only one patient experienced an adverse event, which was managed nonoperatively. Therefore, based on this data, patellar fixation in cementless TKA can be considered a safe technique.

Abstract
Objective Assessment of the treatment trends of Spanish surgeons in clinical practice by making clinical assumptions in Dupuytren's disease (DD).
Material and Method A survey was sent to the members of the Spanish Society for Surgery of the Hand (Sociedad Española de Cirugía de la Mano, SECMA) posing primary and secondary clinical cases. A relationship is established between the selected treatment, the characteristics of the participating surgeons, and the characteristics of the primary clinical cases. Treatment preferences in recurrences are assessed descriptively.
Results In total, 127 surveys were answered. 62.2% of the participants had experience with the use of collagenase and were the basis of the analysis. In primary cases, surgeons with more practice time tended to choose collagenase as treatment for DD. Surgeons who reported higher frequency of collagenase use (67.4% vs. 25.7%) were up to 6 times more likely to indicate such treatment. The patient's age under 50 years was the variable with the greatest association strength for the choice of collagenase treatment (OR = 3.8; CI95% 1.9–7.6). In recurrences, among all clinical cases, the most common answer given by the surgeons was partial fasciectomy.
Conclusions Partial fasciectomy continues to be the most widely used treatment for DD in Spain. In primary cases, collagenase is an alternative adopted by experienced surgeons, and in treatments for young patients. In recurrences, partial fasciectomy is the preferred technique.
Depletion interactions modulate the binding between disordered proteins in crowded environments

Published: June 2020

Significance
The molecular environment in a biological cell is much more crowded than the conditions commonly used in biochemical and biophysical experiments in vitro. It is therefore important to understand how the conformations and interactions of biological macromolecules are affected by such crowding. Addressing these questions quantitatively, however, has been challenging owing to a lack of sufficiently detailed experimental information and theoretical concepts suitable for describing crowding, especially when polymeric crowding agents and biomolecules are involved. Here, we use the combination of extensive single-molecule experiments with established and recent theoretical concepts to investigate the interaction between two intrinsically disordered proteins. We observe pronounced effects of crowding on their interactions and provide a quantitative framework for rationalizing these effects.

AbstractCurrently, there are no harmonized guidelines which govern skin banking in the Asia Pacific region. Therefore, skin banks are either unregulated or rely on their nation’s legislation or international accreditation to uphold their quality standards. A new set of skin banking guidelines was developed through a comprehensive review and collation of best international practices for the Asia Pacific Burn Association (APBA) members, from donor screening and testing, to skin recovery, processing, storage and distribution, and quality assurance. National regulatory requirements reviewed include the European directives, Australia’s Therapeutic Goods Administration and Singapore’s tissue banking standards. Further technical and quality management recommendations are referenced from the American Association of Tissue Banks (AATB), the United States Food and Drug Administration standards and guidance documents, various relevant European guides, Japanese Society of Tissue Transplantation guidelines and the Asia Pacific Association of Surgical Tissue Banking. Adapted mainly from the AATB standards, the new Asia Pacific Burn Association Guidelines for Skin Banking in Therapeutic Applications offer a comprehensive manual, addressing: governance and contracts; staff responsibilities; quality management; facilities, equipment and supplies management; donor consent and testing; and recommendations of good practices pertaining to skin recovery, processing, storage and distribution. Besides complementing current generic regulations, they provide technical specifications of major aspects unaddressed in most legislations. This inaugural set of new regional skin banking guidelines would be a start for regional members of the APBA to adopt, and will hopefully culminate in a set of standards so that, in the long run, skin allografts from this region can be of similar quality, which can simplify import process and facilitate the exchange of allografts between members.

Abstract
Ophiopogon japonicus (Thunb.) Ker-Gawl (Liliaceae), which is named as “Maidong” in China, is widely used in traditional Chinese medicine for treating fever, cough, inflammation, epistaxis, constipation, respiratory disease and gastrointestinal disorders. However, the systematic analysis of chemical constituents of O. japonicus has not been well established because of the complexity and trace. In this paper, an effective and reliable high-performance liquid chromatography coupled to electrospray ionization and quadrupole time-of-flight mass spectrometry method was successfully developed to separate and identify the chemical constituents from O. japonicus. As a result, a total of 30 compounds including steroidal saponins, homoisoflavonoids, allylbenzene, cholest and cryptomeridiol were screened or tentatively identified. Of them, three new steroidal saponins were found and tentatively characterized in O. japonicus. This study provides a meaningful material basis for further quality control and pharmacological research.

Abstract

OBJECTIVES

The anatomical distribution pattern of epidural intraspinal arteries is not entirely understood but is likely to substantially impact maintaining perfusion during segmental artery sacrifice when treating acute and chronic thoraco-abdominal aortic diseases. We investigated the anatomical distribution pattern of intraspinal arteries.

METHODS
Twenty fresh, non-embalmed cadaveric human bodies were studied. Anatomical dissection and investigation of the epidural arterial network were performed according to a standardized protocol. We used a generalized mixed linear model to test whether the presence probability for certain vessels differed between vertebrae/segments.

RESULTS
There was craniocaudal continuity of all ipsilateral longitudinal connections from T1 to L5 by the anterior radicular artery. The mean [±standard deviation (SD)] number of transverse anastomoses was 9.7 ± 2.1. The presence probability of transverse anastomoses along the spine was different between vertebrae (P &lt; 0.0001). There were 2 distribution peaks along the spine: 1 peak around T4–T6 and 1 around T11. The mean (±SD) number of thoracic and lumbar anterior radiculomedullary arteries (ARMAs) was 3.0 ± 1.1. The probability of the presence of ARMAs along the spine was different for each vertebral segment (P &lt; 0.0001). Between ARMAs there were gaps of up to a maximum of 9 vertebrae. All Adamkiewicz arteries were located caudally to T7. The median segment of the Adamkiewicz presence was T10/11.

CONCLUSIONS
The epidural collateral network shows craniocaudal continuity. The number of transverse anastomoses is high. The number of ARMAs is low, and there is considerable variation in their distribution and offspring, which is highly likely to impact perfusion during segmental artery sacrifice when treating thoraco-abdominal aortic disease.
A generalised model for generalised transduction: the importance of co-evolution and stochasticity in phage mediated antimicrobial resistance transfer

Published: June 2020

ABSTRACTAntimicrobial resistance is a major global challenge. Of particular concern are mobilizable elements that can transfer resistance genes between bacteria, leading to pathogens with new combinations of resistance. To date, mathematical models have largely focussed on transfer of resistance by plasmids, with fewer studies on transfer by bacteriophages. We aim to understand how best to model transfer of resistance by transduction by lytic phages. We show that models of lytic bacteriophage infection with empirically derived realistic phage parameters lead to low numbers of bacteria, which, in low population or localised environments, lead to extinction of bacteria and phage. Models that include antagonistic co-evolution of phage and bacteria produce more realistic results. Furthermore, because of these low numbers, stochastic dynamics are shown to be important, especially to spread of resistance. When resistance is introduced, resistance can sometimes be fixed, and at other times die out, with the probability of each outcome sensitive to bacterial and phage parameters. Specifically, that outcome most strongly depends on the baseline death rate of bacteria, with phage-mediated spread favoured in benign environments with low mortality over more hostile environments. We conclude that larger-scale models should consider spatial compartmentalisation and heterogeneous microenviroments, while encompassing stochasticity and co-evolution.
Regulation strength and technology creep play key roles in global long-term projections of wild capture fisheries
Authors: Scherrer Kim , Galbraith Eric 
Published: June 2020

Abstract
Many studies have shown that the global fish catch can only be sustained with effective regulation that restrains overfishing. However, the persistence of weak or ineffective regulation in many parts of the world, coupled with changing technologies and additional stressors like climate change, renders the future of global catches uncertain. Here, we use a spatially resolved, bio-economic size-spectrum model to shed light on the interactive impacts of three globally important drivers over multidecadal timescales: imperfect regulation, technology-driven catchability increase, and climate change. We implement regulation as the adjustment of fishing towards a target level with some degree of effectiveness and project a range of possible trajectories for global fisheries. We find that if technological progress continues apace, increasingly effective regulation is required to prevent overfishing, akin to a Red Queen race. Climate change reduces the possible upper bound for global catches, but its economic impacts can be offset by strong regulation. Ominously, technological progress under weak regulation masks a progressive erosion of fish biomass by boosting profits and generating a temporary stabilization of global catches. Our study illustrates the large degree to which the long-term outlook of global fisheries can be improved by continually strengthening fisheries regulation, despite the negative impacts of climate change.
Personalized external aortic root support

Published: June 2020

Abstract

OBJECTIVES
Implantation of a personalized external aortic root support (PEARS) can prevent dilatation of the aortic root and ascending aorta in patients with aortopathy of various aetiologies. Because PEARS is an emerging technology, all aspects concerning indications, surgical technique and safety should be elucidated. Our goal was to summarize all of these aspects so that physicians and patients would have sufficient information to evaluate this alternative approach.

METHODS
Between April 2004 and March 2020, 317 patients underwent PEARS operations at 25 surgical centres in 9 countries.

RESULTS
The most common indication was Marfan syndrome (57%). The single perioperative death represented a mortality of 0.3%. The long-term experience comprises 871 patient/years with 1 patient living for 15 years and 19 patients living for more than 10 years.

CONCLUSIONS
PEARS seems to be a promising method of treatment of dilatation of the aortic root and/or ascending aorta. Multicentre observational studies are needed to gain more experience because this operation is still uncommon and the number of operations per surgeon/centre is low.
The Market for Surprises: Selling Substitute Goods Through Lotteries
Authors: Balestrieri Filippo , Izmalkov Sergei , Leao Joao 
Published: June 2020

Abstract
In this paper, we solve the revenue maximization problem of a multi-product monopolist when the products are substitutes. We consider a Hotelling model with two horizontally differentiated goods located at the endpoints of the segment. Consumers are located uniformly on the segment; their valuations for each good are equal to the base consumption value minus distance costs. When the base consumption value is high, the seller maximizes her expected profit by offering a menu of base and opaque goods. In particular, a single half-half lottery over base goods is optimal under concave and linear costs. When base consumption value is low, only base goods are sold. Finally, when base consumption value is intermediate, the optimal mechanism may entail the offering of lotteries with the positive probability of no delivery. Our findings can explain the emergence of opaque goods sales (e.g., hotel bookings without a complete description of the hotel through hotwire.com or priceline.com) as the outcome of the industry’s search for the optimal selling scheme.
