Published: August 2023

AbstractBackgroundOsteochondral allograft (OCA) transplantation is a clinically and cost-effective option for symptomatic cartilage defects. In 2017 we initiated a program for OCA transplantation for complex chondral and osteochondral defects as a UK tertiary referral centre.AimTo characterise the complications, re-operation rate, graft survivorship and clinical outcomes of knee OCA transplantation.MethodologyAnalysis of a prospectively maintained database of patients treated with primary OCA transplantation from 2017 to 2021 with a minimum of one-year follow-up. Patient reported outcome measures (PROMs), complications, re-operations and failures were evaluated.Results37 patients with 37 knee OCA procedures were included (mean age 31.6 years [16–49 years]). Mean BMI 26.6 kg/m2 (19.1–35.9 kg/m2). The mean chondral defect size was 3cm2 (1.2–7.3 cm2). Mean duration of follow-up was 3.1 years (1–5.3 years). 16 patients underwent meniscal allograft transplantation (MAT), 6 underwent osteotomy and 4 underwent ligament reconstruction as concurrent procedures. Significant improvements in mean PROMs were noted at 12 months. 16 patients had reoperations of which 5 had more than one surgery. Of these patients 6 were related to OCA (mainly debridement and revision OCA in one patient), and the remainder were related to additional procedures including removal of plate in 2 patients. The overall failure rate was 1 in 37 patients (3%).ConclusionsEarly experience of OCA as a treatment option for complex chondral and osteochondral lesions in the knee shows satisfactory results. The reoperation rate is high but at mean follow-up of 3.1 years the survival rate was 97%.

Published: August 2023

AbstractIntroductionTotal joint arthroplasty (TJA) is one of the commonest and most successful orthopaedic procedures, used for the management of end-stage arthritis. With the recent introduction of robotic assisted joint replacement, Computed Tomography (CT) has become part of required pre-operative planning.The aim of this study is to quantify and characterise incidental CT findings, their clinical significance, and their effect on planned joint arthroplasty.MethodologyAll consecutive patients undergoing an elective TJR (hip or knee arthroplasty) were retrospectively identified, over a 3-year period (December 2019 and December 2022). Data documented and analysed included patient demographics, type of joint arthroplasty, CT findings, their clinical significance, as well as potential delays to the planned arthroplasty because of these findings and subsequent further investigation.ResultsA total of 624 patients (637 studies, 323 (51.8%) female, 301 (48.2%) male) were identified of which 163 (25.6%) showed incidental findings within the long bones or pelvis. Of these 52 (8.2%) were significant, potentially requiring further management, 32 (5.0%) represented potential malignancy and 4 (0.6%) resulted in a new cancer diagnosis.ConclusionIt is not currently national standard practice to report planning CT imaging as it is deemed an unnecessary expense and burden on radiology services. Within the study cohort 52 (8.2%) of patients had a significant incidental finding that required further investigation or management and 4 (0.6%) had a previously undiagnosed malignancy. In order to avoid the inevitability of a missed malignancy on a planning CT, we must advocate for formal reports in all cases.
COMPARISON OF INTRAVENOUS VERSUS TOPICAL TRANEXAMIC ACID IN BLOOD LOSS REDUCTION IN BILATERAL TOTAL KNEE ARTHROPLASTY
Authors: Sidhu Gur Aziz Singh 
Published: August 2023

AbstractIntroductionMultiple strategies, used either in isolation or combination, are available to reduce the need for post-operative blood transfusion in joint replacements. Amongst them, the use of tranexamic acid (TXA) has been rising and this study was conducted to compare the efficacy of topical and intravenous TXA in bilateral total knee replacement patients.Materials and methodsRandomised prospective study with 120 patients (male: female: 25:95) undergoing bilateral TKA. Patients were divided into two groups A and B after computer randomization, who received intravenous or topical (intra-articular) TXA respectively.ResultsThe average haemoglobin loss in intravenous group was 90.2379 g/L as compared to 39.137 g/L in topical group (p < 0.005). Moreover, there was reduction in blood loss in topical (330.1602 ml) as compared to intravenous group (764.9622 ml). The blood transfusion rate was more for the intravenous group (average 1.73 units) than for the topical group (average 0.75, unit). WOMAC score at 6 weeks in the intravenous group was 12.50, and in the topical group was 7.23 (p value < 0.001).ConclusionTopical TXA is better than intravenous TXA for reduction of blood loss, which also reduces the need for blood transfusion in bilateral TKA patients.
‘OBVIOUSLY BECAUSE IT'S A TEAR IT WON'T NECESSARILY MEND ITSELF.’ A QUALITATIVE STUDY OF PATIENT EXPERIENCES AND EXPECTATIONS OF TREATMENT FOR A MENISCAL TEAR

Published: August 2023

AbstractIntroductionRecent research has questioned the role of arthroscopic meniscectomy in patients with a meniscal tear leading to the development of treatment recommendations for these patients. There is a clear need to understand patient perceptions of living with a meniscal tear in order to plan future research and treatment guidelines.AimsTo explore the experiences and expectations of treatment of young patients with a meniscal tear of the kneeMethodologyTen participants diagnosed with a meniscal tear were recruited from the METRO cohort study using a purposive sampling strategy. These patients underwent semi-sructured interviews between April and May 2021. Thematic analysis was used to code the transcripts and generate key themes in order to describe the data.ResultsThemes identified relate to the broad areas of: the effect of symptoms, the expericne of the clinical consultation and the experience of the treatment modality undertaken. Meniscal tears have a profound impact on pain and many patients experience effects on their family and financial life in addition to physical symptoms. Participants expected the majority of their management to occur in secondary care and most thought surgery would be a definitive treatment, while the effectiveness of physiotherapy could not be guaranteed as it would not fix the physical tear.ConclusionPatient experience of meniscal tear may not correspond with current available clinical evidence. Clinicians should consider the common misconceptions highlighted in this study when conducting a consultation and pre-empt them to optimally manage patient expectations.
Health facility availability and readiness for family planning and maternity and neonatal care services in Nepal: Analysis of cross-sectional survey data
Authors: Rai Pramila , Ackerman Ilana N. , O’Connor Denise A. , Gorelik Alexandra , Buchbinder Rachelle 
Published: August 2023

Objectives
To determine the availability and readiness of health facilities to provide family planning, antenatal care and basic emergency obstetric and newborn care in Nepal in 2021. Secondary objectives were to identify progress since 2015 and factors associated with readiness.

Method
This is a secondary analysis of cross-sectional Nepal Health Facility Survey (NHFS) data collected in 2015 and 2021. The main outcome measures were availability and readiness of family planning, antenatal care, and basic emergency obstetric and newborn care services. Readiness indices were calculated using WHO-recommended service availability and readiness assessment (SARA) methods (score range 0 to 100%, with 100% indicating facilities are fully prepared to provide a specific service). We used independent t-tests to compare readiness indices in 2015 and 2021. Factors potentially associated with readiness (rurality setting, ecological region, managing authority, management meeting, quality assurance activities, and external supervision) were explored using multivariable linear regression.

Results
There were 940 and 1565 eligible health facilities in the 2015 and 2021 surveys, respectively. Nearly all health facilities provided family planning (2015: n = 919 (97.8%); 2021: n = 1530 (97.8%)) and antenatal care services (2015: n = 920 (97.8%); 2021: n = 1538 (98.3%)) in both years, but only half provided delivery services (2015: n = 457 (48.6%); 2021: n = 804 (51.4%)). There were suboptimal improvements in readiness indices over time: (2015–21: family planning 68.0% to 70.9%, p<0.001, antenatal care 49.5% to 54.1%, p<0.001 and basic emergency obstetric and newborn care 56.7% to 58.0%, p = 0.115). The regression model comprising combined datasets of both NHFSs indicates facilities with regular management meetings and/or quality assurance activities had significantly greater readiness for all three indices. Similarly, public facilities had greater readiness for family planning and basic emergency obstetric and newborn care while they had lower readiness for antenatal care.

Conclusions
Readiness to deliver family planning, antenatal care and basic emergency obstetric and newborn care services in Nepal remains inadequate, with little improvement observed over six years.

Published: August 2023

Introduction
The number of brain MRI with contrast media performed in patients with cognitive impairment has increased without universal agreement. We aimed to evaluate the detection rate of contrast-enhanced brain MRI in patients with cognitive impairment.

Materials and methods
This single-institution, retrospective study included 4,838 patients who attended outpatient clinics for cognitive impairment evaluation and underwent brain MRI with or without contrast enhancement from December 2015 to February 2020. Patients who tested positive for cognitive impairment were followed-up to confirm whether the result was true-positive and provide follow-up management. Detection rate was defined as the proportion of patients with true-positive results and was compared between groups with and without contrast enhancement. Individual matching in a 1:2 ratio according to age, sex, and year of test was performed.

Results
The overall detection rates of brain MRI with and without contrast media were 4.7% (57/1,203; 95% CI: 3.6%–6.1%) and 1.8% (65/3,635; 95% CI: 1.4%–2.3%), respectively (P<0.001); individual matching demonstrated similar results (4.7% and 1.9%). Among 1,203 patients with contrast media, 3.6% was only detectable with the aid of contrast media. The proportion of patients who underwent follow-up imaging or treatment for the detected lesions were significantly higher in the group with contrast media (2.0% and 0.6%, P < .001).

Conclusions
Detection rate of brain MRI for lesions only detectable with contrast media in patients with cognitive impairment was not high enough and further study is needed to identify whom would truly benefit with contrast media.

Published: August 2023

Abstract
Wood and bamboo are the greenest renewable materials used for construction, furniture, and decor from the ancient ages. However, wood and bamboo have intrinsic faults like durability, ductility, physical and mechanical strength, and stability, limiting their applications in the industry. On the other hand, nanotechnology is a popular technology having numerous applications in different fields, resulting in a significant increase in expectations among academics, investors, the government, and industries. In contrast, nanotechnology can protect wood and bamboo from extreme conditions (bacteria, climate, etc.) by improving physicochemical characteristics because of its unique features. Nowadays, the trend of merging nanotechnology and forest industries to overcome the limitations mentioned above and get economically sustainable materials for construction, furniture manufacturing, flexible sensors developments, energy storage, battery manufacturing, and many more is increasing. Presently, several reviews on wood and bamboo modification by nanoparticles and nanomaterials have already been published. But, at this time, this study is essential because it aims to provide a brief guide about the recently developed eco-friendly sustainable materials from wood and bamboo, their uses, and how they can affect people’s daily life and helps to point out the gap of the current knowledge. In addition, we briefly describe the conventional and modern modification methods, including the influence of nanomaterials on wood and bamboo structures. This article is outlined as follows: The first phase of the review deals with wood and bamboo modification methods. The second phase explains how the modification method improves the properties of wood and bamboo materials, and the last step will describe the recent innovation of wood and bamboo materials.

Zusammenfassung
Dank einer langen Geschichte der Erforschung der Herkunft, der Verteilungsnetze und der Bewertung der kulturellen Bedeutung von Bernstein, nimmt die Informationsmenge über die Komplexität der Tauschnetzwerke im bronzezeitlichen Europa stetig zu. Die vorliegende Studie stellt die nächste Stufe in der Entwicklung der Forschung zu diesem Thema dar. Sie präsentiert eine Synthese des bisherigen Wissens über das Vorkommen von Bernstein in der Frühbronzezeit auf dem Gebiet der heutigen Slowakei sowie neue Erkenntnisse über die Herkunft des Rohmaterials und die absolute Chronologie der Funde von drei ausgewählten Fundstellen im östlichen Teil des Landes.
Auf der Grundlage der gewonnenen Informationen werden Schlüsselfragen im Zusammenhang mit der Herkunft des Bernsteins, dem Kontext seiner Ablagerung und den chronologischen Mechanismen seiner Verbreitung im untersuchten Gebiet diskutiert. Die erzielten Ergebnisse sind ermutigend genug, um die Anfänge der Bernsteinannahme, seine weitere Wahrnehmung und Bewertung durch Tauschstrategien zu vergleichen und zu klären, wobei Bernstein eher als Nebenprodukt eines komplexeren Handelssystems bereitgestellt zu werden scheint, das sich in erster Linie auf den Metalltausch konzentriert.
Five hoards in eighty years. Landscape perspectives on new Bronze Age hoard finds around Lake Mälaren in Sweden
Authors: Rundkvist Martin 
Published: August 2023

Abstract
Since 1941, only five Bronze Age hoards have been found in the four provinces around Sweden’s Lakes Mälaren and Hjälmaren: three in Uppland, two in Södermanland, none in Västmanland or Närke. The most recent one appeared in 2016. Here each hoard is discussed in terms of its date, the regional affiliation of its contents, and its landscape situation. They all date from Per. V–VI, c. 950–520 cal BC, and are entirely dominated by locally made objects. Two sites are apparently peripheral in relation to period settlement and to other deposition sites, while two are in an area of dense settlement and were found during the same military metal detector campaign. The steep drop in new hoard finds after World War II is discussed, and Sweden’s restrictive metal detector legislation is identified as the main reason that only five hoards have come to light in the area over the past eighty years.

Published: August 2023

Abstract
Numerical calculation of infrared emission from hot plume is of great significance for flight monitoring and detections. In this paper, the SNB (statistical narrow band) model established with parameters derived from the high-resolution spectral database HITEMP 2010 is used to perform the hot plume infrared signature simulations. Accuracy of the model is examined by the exact LBL (line by line) method, which proves the model’s reliability to predict radiative properties of combustion gases. In the application part, the SNB model is used to analyze infrared signatures of aircraft plumes cruising at different flight altitudes. The results show that cruising at a higher-altitude will obviously reduce the plume infrared emission. Besides, the plume infrared emissive energy mainly concentrates in a special wavenumber interval and can be strongly absorbed by atmosphere.

Published: August 2023

Abstract
The experimental system of pulse detonation engine (PDE) is set up to investigate the influence of equivalence ratios on detonation noise characteristics. The research results show that as the equivalence ratio increasing, the amplitudes of detonation noise in all angles and locations increase, and the tB
also increases simultaneously, while the tA
increases first and then decreases. The equivalence ratio also has a great influence on the intensity of the detonation noise signal in the frequency band of 10–100 Hz, which increases firstly and then decreases with the increase of the equivalence ratio, and the maximum value is obtained at equivalence ratio of 1.1. The results are of great significance to study the mechanism of detonation noise and promote the process of the engineering application.

Published: August 2023

AbstractPredictively linking taxonomic composition and quantitative ecosystem functions is a major aspiration in microbial ecology, which must be resolved if we wish to engineer microbial consortia. Here, we have addressed this open question for an ecological function of major biotechnological relevance: alcoholic fermentation in wine yeast communities. By exhaustively phenotyping an extensive collection of naturally occurring wine yeast strains, we find that most ecologically and industrially relevant traits exhibit phylogenetic signal, allowing functional traits in wine yeast communities to be predicted from taxonomy. Furthermore, we demonstrate that the quantitative contributions of individual wine yeast strains to the function of complex communities followed simple quantitative rules. These regularities can be integrated to quantitatively predict the function of newly assembled consortia. Besides addressing theoretical questions in functional ecology, our results and methodologies can provide a blueprint for rationally managing microbial processes of biotechnological relevance.
