Trends in Tattoo-Related Google Search Data in the United States: Time-Series Analysis
Authors: Kiszla Benjamin Matthew , Harris Mia Broughton
Published: November 2022

Background

Tattoos are becoming increasingly common in the United States. However, little information is available to help clinicians anticipate where, when, and on what topics patients will seek guidance regarding tattoo care, complications, and removal.

Objective

The aim of this study was to model web searches concerning general interest in tattoo application, tattoo removal, and the geolocation of tattooing services.

Methods

Relative search volumes (RSVs) were elicited from Google Trends, filtered to web searches made in the United States between January 15, 2008, and October 15, 2022. Longitudinal data were analyzed in GraphPad Prism and geospatial data were visualized with Datawrapper for general interest searches (tattoo and tattoo removal), aggregated geolocating searches (eg, tattoo shops near me), and symptomatic searches relating to adverse effects (eg, itchy tattoo). Results were compared to previous global literature and national surveys of tattoo prevalence.

Results

In the United States, the search terms tattoo and tattoo removal have experienced stable RSVs over the past 14 years, with both showing peaks in the summer and troughs in the winter. RSVs for search terms that geolocate tattooing services have experienced a general increase in use since 2008. A compilation of results for all collated geolocating search terms localized these searches mainly to the American South, with lesser involvement in the eastern Midwest and inland West. Increased search interest in the Southeast at the expense of more populous coastal states and Great Plains or western Midwest states reflects the ongoing harmonization of tattoo prevalence across regions, as shown by national surveys. Searches for symptoms related to adverse reactions to tattooing experienced an increase over the period of interest, with the same distribution as previous global findings.

Conclusions

Clinicians should be aware of an increase in search interest regarding tattoos and their removal, especially during the summer months in the Southeast and Midwest. This increase in interest is occurring together with increased tattoo prevalence and increased search interest for adverse reactions in a country lagging behind in tattoo ink regulation.

Published: November 2022

Social media has become one of the major data sources for social studies through users’ expressions, such as significant moments in their daily life or their feelings and perceptions toward specific discussion topics. In health care, social media is thoroughly used to study people’s discourse on ailments and derive insights into the impact of ailments on patients’ quality of life. Recently, there has been an increasing interest in applying machine learning algorithms to enhance the prediction of ailments through users’ social media data. In this study, nearly 800 million posts were retrieved from Twitter through preprocessing and running the time-aware ailment topic aspect model (T-ATAM) to predict diseases, symptoms, and remedies for two chronic conditions, namely sleep apnea and chronic liver diseases. The study was conducted on English tweets emitted during 2018, most of which were from European countries and the United States. The data were processed using T-ATAM by regions, timestamps, and treatment, namely continuous positive airway pressure (CPAP), to see the differences in the distributions of top diseases along with the top symptoms and remedies in different regions; timestamps; as well as before, during, and after CPAP was introduced. Based on approximately 331,000 tweets related to liver diseases and 1 million tweets on sleep apnea, various visualizations of statistics are displayed, including world maps, word clouds, and histograms. Results of this study indicate that depression and drinking are the leading symptoms of liver diseases; meanwhile, lack of nighttime sleep and overworking are considered the main factors of sleep apnea.

Published: November 2022

Sekarang ini perkembangan telekomunikasi pada jaringan nirkabel berkembang dengan sangat cepat. Perkembangan telekomunikasi yang cepat tersebut disebabkan oleh kebutuhan manusia terhadap informasi secara cepat dan dapat diakses di mana saja. Salah satu perangkat pada sistem telekomunikasi jaringan nirkabel adalah antena. Kebutuhan antena yang dapat bekerja pada beberapa frekuensi jaringan nirkabel sangat diperlukan pada perangkat sistem telekomunikasi. Oleh karena itu, penelitian ini mengusulkan rancangan sebuah antena mikrostrip yang dapat bekerja pada dua buah frekuensi jaringan nirkabel secara bersamaan, yaitu Wi-Fi dan telekomunikasi seluler generasi kelima (5G). Antena mikrostrip dirancang dengan menggunakan dua buah slot, yaitu satu slot berbentuk cincin persegi terputus dan satu slot lagi berbentuk huruf U terbalik. Adapun frekuensi Wi-Fi dan 5G yang bekerja pada antena ini adalah 2,45 GHz dan 3,3 GHz. Frekuensi resonansi pada antena mikrostrip ini dipengaruhi oleh panjang slot. Antena dirancang dan difabrikasi menggunakan substrat Rogers 5880 yang memiliki permitivitas relatif bahan (er) 2,2, loss tangen (d) 0,0009, dan ketebalan 1,575 mm. Namun, sebelum difabrikasi, terlebih dahulu rancangan antena disimulasikan menggunakan simulator Ansys HFSS. Simulator Ansys HFSS merupakan simulator untuk mendesain komponen yang menggunakan gelombang elektromagnetik, di antaranya antena. Hasil pengukuran koefisien refleksi pada desain antena ini memperlihatkan hasil yang sangat bagus untuk kedua buah frekuensi tersebut, jika dibandingkan dengan hasil simulasi. Pada hasil simulasi, koefisien refleksi memberikan lebar pita sebesar 123 MHz pada rentang frekuensi 2.412–2.535 MHz, sedangkan hasil pengukuran memberikan nilai lebar pita sebesar 153 MHz di rentang frekuensi 2.402-2.555 MHz untuk penerapan frekuensi Wi-Fi. Pada frekuensi 5G, diperoleh lebar pita pengukuran sebesar 87 MHz, pada rentang 3.260-3.347 MHz. Hasil pengukuran tersebut sesuai dengan hasil simulasi, yang memperoleh lebar pita 88 MHz pada rentang 3.248–3.336 MHz. Oleh karena itu, dapat disimpulkan bahwa fabrikasi dari desain antena ini dapat dipakai untuk kedua aplikasi tersebut.

Published: November 2022

Through-Wall Radar (TWR) telah banyak diaplikasikan dalam berbagai bidang, salah satunya dalam pencarian atau evakuasi korban bencana yang tertimpa reruntuhan. TWR merupakan pengaplikasian sistem radar yang bekerja pada rentang frekuensi yang lebar atau ultra-wideband (UWB) sehingga memiliki tingkat akurasi yang tinggi dalam mendeteksi objek di balik dinding. Pada penelitian ini, antena Vivaldi digunakan untuk mendapatkan tingkat resolusi yang tinggi karena mampu bekerja pada UWB. Untuk menghasilkan tingkat akurasi yang tinggi, dibutuhkan parameter seperti karakteristik dielektrik untuk setiap jenis penghalang yang digunakan. Eksperimen pada penelitian ini dilakukan untuk mengetahui pengaruh dinding penghalang pada deteksi tanda vital pernapasan menggunakan sistem radar. Sistem radar dimodelkan menggunakan dua metode, yaitu dengan vector network analyzer (VNA) dan bladeRF. Eksperimen dilakukan dalam beberapa tahap, yaitu pembuatan desain sistem eksperimen, pengambilan data eksperimen, pengolahan hasil data eksperimen, dan analisis hasil eksperimen. Jenis dinding yang digunakan pada penelitian ini adalah dinding bata Hebel dan dinding kayu. Hasil data eksperimen pada penelitian ini digunakan untuk menganalisis pengaruh penghalang pada deteksi tanda vital pernapasan menggunakan sistem radar. Eksperimen menggunakan VNA sebagai sistem radar dilakukan untuk menganalisis pengaruh dinding penghalang pada deteksi target di balik dinding penghalang. Eksperimen menggunakan bladeRF sebagai sistem radar dilakukan untuk membuktikan ada atau tidaknya pengaruh penghalang pada deteksi tanda vital pernapasan menggunakan sistem radar. Hasil pengukuran menunjukkan bahwa penurunan amplitudo sinyal peak-to-peak terbesar terjadi pada deteksi target dengan jarak 125 cm, yaitu sebesar 11,51 dB, dan delay sebesar 0,084 ns, saat menggunakan penghalang bata Hebel. Sementara itu, saat menggunakan penghalang kayu, penurunan rata-rata amplitudo sinyal peak-to-peak sebesar 2,968 dB dan delay sebesar 0,006 ns.
A Review of the Research on Transnational Environmental Tort Law
Authors: Wang Chaoyi
Published: November 2022

The accelerated pace of globalization has brought about rapid economic development, while the number of transnational environmental pollution problems is also increasing. On the one hand, the imbalance of the global economy has intensified, and transnational corporations have taken advantage of the low cost and low standards of environmental protection in developing countries to transfer polluting industries; On the other hand, with the awakening of citizen’s environmental awareness in developing countries, more and more people realize that their own legal provisions are not enough to compensate for their losses, so they choose to go overseas to appeal to the home country courts. Based on the review of relevant literature in China and foreign theoretical circles in recent years, this paper summarizes it from three aspects: jurisdiction, application of law and transnational corporations, with a view to promoting the improvement of China’s transnational environmental tort law.

Published: November 2022

Mango is widely consumed all over the world due to its unique flavor, remarkable taste, nutritional and medicinal characteristics. Multan is an important region in Pakistan with suitable weather conditions for the growth of mango plants. In this study, we successfully optimized the doses of affordable fertilizers for better growth and development of mango plants. Besides, we described the chemical and physical analysis with various recipes and combinations of fertilizers. Our findings show that Calcium Ammonium Nitrate, Single Super Phosphate and Sulphate of Potash, release easily Nitrogen, Phosphate, and Potassium for better growth of plants along with some micronutrient. These optimized doses can be purchased and afforded by farmers easily and provide good and extraordinary results. Further experiments revealed that the combination of three controlled doses provides better results when compared to a single of dual combinations and if the concentration of doses rises to an extent this results in the wilting and death of plants.

Evaluación experimental de la resistencia del concreto modificado con caucho
Authors: Retama Velasco Jaime , Heras Cruz Ricardo
Published: November 2022

En este trabajo se reportan resultados parciales derivados de una serie de experimentos de laboratorio, con los que se estudia el  empleo de caucho de llantas de desecho como agregado en concreto de cemento Portland, reemplazando el 10% en peso del agregado pétreo. Se estudiaron tres mezclas de concreto: simple, con caucho grueso y con caucho fino. Los tamaños de las  partículas del caucho grueso variaron de 6.32 - 9.53 mm, mientras que para el fino iban de 2.35 - 2.80 mm. La influencia de este material en la resistencia mecánica del concreto se evaluó mediante cilindros y vigas, a los 28 días de edad, bajo condiciones de carga uniaxial de compresión, tracción indirecta y flexión. Para las tres condiciones de carga estudiadas, los resultados  experimentales mostraron una reducción de la resistencia del concreto, cuando se sustituye parte del agregado pétreo con caucho. La mezcla de concreto con partículas finas de caucho presentó un mejor comportamiento mecánico que la mezcla con partículas gruesas; incluso en condiciones de flexión, la resistencia era casi igual a la del concreto simple.

Evaluación de la calidad nutricional en pasturas de gramíneas perennes relacionada con el estado fenológico y el ambiente en el Sur de Santa Cruz
Authors: Gil Manuel Jesús , Utrilla Víctor
Published: November 2022

En la Patagonia Austral la introducción de pasturas destinadas al uso estratégico en las áreas de mayor potencial representa una alternativa de manejo que permitiría aumentar la productividadde los sistemas ganaderos extensivos. En este contexto, la calidad nutricional de los recursos forrajeros disponibles constituye un aspecto relevante vinculado con la eficiencia de aprovechamiento y la respuesta productiva del ganado. En virtud de ello, se realizó un estudio durante dos años sobre pasturas de agropiros y pasto ovillo (PO) implantadas en secano en el Sur de Santa Cruz. En clausuras permanentes instaladas, se determinaron en tres estados fenológicos (vegetativo, inicio de floración y floración avanzada) de las pasturas el material vivo y muerto (MV y MM) y la calidad nutricional mediante análisis químicos de proteína bruta(PB), digestibilidad de la materia seca (DMS) y producción de gas in vitro. Se realizaron muestreos de suelos para determinar el contenido hídrico y se relevaron variables climáticas. Las variables se analizaron en función del estado fenológico en un diseño completamente aleatorizado con tres repeticiones. La PB de ambas pasturas se correlacionó con el MM. El MVdel PO se correlacionó con la humedad edáfica mientras que el MM con la temperatura del aire. En ambas pasturas, el avance fenológico provocó reducciones significativas en el MV, PB y DMS y aumento en el MM, con cambios mayores en el PO.Finalmente, la pandemia por COVID-19 y las medidas sanitarias adoptadas por la provincia de Santa Cruz impidieron analizar todos los parámetros nutricionales previstos.

Microorganismos de montaña, una alternativa para la biofertilización de cultivos agrícolas
Authors: Medina Valencia Diana Cristina , Obando Anaya Erika Tatiana
Published: November 2022

(a) Contextualización: Los microorganismos de montaña (MM) se encuentran en la materia orgánica de suelos poco intervenidos, esto quiere decir suelos que han recibido pocos tratamientos químicos, que no han sido incinerados de manera constante y/o sometidos a procesos de producción agropecuaria como ganadería extensiva o monocultivos. Estos suelos sin intervenir a lo largo del tiempo, permite conservar la microfauna, bacterias y hongos, que a su vez logran realizar de manera acelerada la descomposición de la materia orgánica y la degradación de sustancias tóxicas y así conservar las características fisicoquímicas del suelo que hacen que estos sean más fértiles y productivos. (b) Vacío de conocimiento: Aunque el resultado de diferentes investigaciones demuestra la eficiencia de los Microorganismos de Montaña como biofertilizante en diferentes cultivos agrícolas, no se cuenta con una documentación o base de datos caracterizada científicamente respecto al tema. Por esta razón, el estudio documental de los microorganismos de montaña se convierte en una potencial riqueza científica y tecnológica. (c) Propósito: Esta revisión bibliográfica se realiza con el objeto de reconocer experiencias relacionadas con la aplicación de microorganismos de montaña (MM) como alternativa sostenible para la producción de diferentes tipos de cultivos. (d) Metodología: Se hace una revisión sistemática sobre las investigaciones realizadas respecto a los microorganismos de montaña, especialmente en Latinoamérica y Colombia. Se fundamenta en la revisión de diferentes bases de datos, sobre estudios científicos realizados en este tema, y a partir de allí se determinó los avances del uso de los microorganismos de montaña como alternativa para la biofertilización en cultivos agrícolas. (e) Resultados y conclusiones: Se ha encontrado de manera general que el uso de microorganismos de montaña (MM) como biofertilizantes en cultivos agrícolas, no solo permite un impacto positivo en el medio ambiente, sino que además logra hacer de la agricultura una actividad sostenible, produciendo alimentos orgánicos con mayor biomasa y haciendo más eficiente la producción.

Published: November 2022

Effective therapies to reduce ischemia/reperfusion and
hypoxia/reoxygenation injury are currently lacking. Borneol has a clear
protective effect on ischemia-reperfusion injury, and its protective
effect on myocardial hypoxia/reoxygenation and its mechanism have
remained to be elucidated. This study investigated the protective
effects of borneol on H9C2 cardiomyocytes during hypoxia/reoxygenation
injury and to explore the underlying molecular mechanisms. H9C2 rat
cardiomyocytes were cultured, the MIRI model was established by hypoxia
for 5h and reoxygenation for 24h. The cells were divided into control
group, hypoxia/reoxygenation group (H/R group), (low-, medium-, high-)
dose borneol group. Borneol administration groups were pre-treated for
12h with different doses of borneol prior to hypoxia/reoxygenation, 24h
after reoxygenation, the cells or culture medium were collected for
testing. The results showed that borneol has no cytotoxicity and can
enhance the viability of cardiomyocytes, significantly increased the SOD
content, significantly decreased LDH leakage in cell culture medium, and
reduced evidently the apoptosis rate, down-regulated the expression of
Bax and Caspase-3. In conclusion, this study demonstrated that borneol
has a definite protective effect on hypoxia/reoxygenation-induced injury
of rat cardiomyocytes, and its protective mechanism can be related to
the inhibition of apoptosis by reducing the expression of Bax and
Caspase-3.

overcome the drawbacks of conventional approaches. In spite of excellent
effectiveness of deep neural networks in detection of the correct class
for bone age, they have a significant degree of complexity due to the
numerous parameters they employ for each ROI. Therefore, they are not
suitable for implementation in edge devices with limited resources. In
this paper, we propose a BAA method using a hybrid knowledge
distillation (KD) paradigm in order to conquer this difficulty by
mapping different ROIs into a single ROI. In this regard, the student
receives knowledge from a teacher network that has been pre-trained on
six ROIs including bones of five fingers and the wrist, transfers the
knowledge of its final response layer and internal layers to the
student. Then, six student models each of which is constructed based on
just one of these ROIs, while receiving the information of the teacher
model by matching the feature maps of intermediate layers and last
output of teacher with those of student in distillation modules.
Empirical results on Digital Hand Atlas (DHA) report that our student
model trained on one ROI obtains 95% accuracy on 19 classes of bone age
makes it appropriate for medical IoT deployment. Also, it has
competitive performance compared to the other state-of-the-art BAA
studies, and performance analysis of our KD with three base KD models
indicates superiority of our introduced method.

Objective To systematically explore the association between
pathogenic/likely pathogenic copy number variations (pCNV) and
ultrasonographic anomalies and soft markers. Design Retrospective cohort
study. Setting Data were obtained from multiple centers in china.
Population or Sample Fetuses performed low-pass genome sequencing and
ultrasonography between 2016 and 2020. Method The yields of pCNV under
various ultrasonographic indications were compared with that of fetuses
with no identifiable anomalies. In addition, the ultrasonographic
characteristics of aneuploidy and pCNV were described in comparison with
those of fetuses without chromosomal aberrations. Main Outcome Measures
Yields of aneuploidy and pCNV in different ultrasonographic indications.
Results Ten of the 12 ultrasonographic anomalies had significantly
higher yield of pCNV, except for fetal hydrops and abnormal amniotic
fluid, of which the gastrointestinal, facial, respiratory systems, and
abdominal wall defect were rarely reported. Similarly, five of the 12
soft markers had significantly higher yield of pCNV, with single
umbilical artery being rarely reported. Furthermore, this study reported
that four duplications/deletions were associated with novel
ultrasonographic findings. Conclusions Based on specific
ultrasonographic phenotypes, prenatal genetic testing could be
considered in a tailored fashion. Keywords Low-pass genome sequencing;
ultrasonographic anomaly; soft marker; copy number variations;
aneuploidy; prenatal diagnosis Tweetable abstract Fetuses with
structural anomalies and specific soft markers are recommended for copy
number variations analysis
Optimization of hhv and energy yield from torrefaction of Albizia zygia wood- calcium hydrogen phosphate catalyst blends using optimal combined design

Published: November 2022

The over-reliance on fossil fuels as a primary source of energy is partly
responsible for the increase in carbon dioxide (CO2), depletion of the ozone
layer, and general environmental pollution. In this study, torrefaction of
Albizia zygia wood-calcium hydrogen phosphate (CaHPO4) catalyst blends was
carried out in a tubular furnace to examine the impacts of temperature,
time, and particle size on higher heating value (HHV) and energy yield (EY).
Albizia zygia wood was obtained at an industrial sawmill junkyard nearby
Kwara State University, dried, crushed, and sieved into 1 - 3 mm particle
size. Optimal Combined Design (OCD) was employed for the design, modelling,
and optimization of HHV and EY under the ranges of selected temperature (200
- 300?C), residence time (15 - 30 min), and particle size (1 - 3 mm) in an
inert environment tubular furnace. The results of the analysis indicated
that the temperature of 245?C, time of 22 min, and size of the particle 3
mm yielded a maximum HHV of 19.59 MJ/Kg and EY of 76.37% respectively. Also,
the addition of catalyst (CaHPO4) at 10% reduced the ash content but
enhanced the fixed carbon content of the biochar. The mathematical models
for the HHV and EY for the torrefaction using the OCD imply an excellent fit
with R2 of 0.92 and 0.96, respectively. The prediction accuracy indicates
that OCD can be deployed for the accurate prediction of HHV and EY in
torrified biomass.

This research focuses on the decomposition temperature of a large sheep horn
from Haveri District, Karnataka, India, which is 302.9?C. It also
demonstrates the possible use of large sheep horn in the aerospace industry.
It can be utilised as a Thermal Barrier Coating (TBC) in high-pressure
compressor blades of jet engines. Because of its poor thermal conductivity
and specific heat capacity, it is a superb insulator, and temperatures
throughout the TBC take around 10 minutes to match.
Sustainable advanced roads that absorb tonnes of CO2 annually and become more resistant using Olivine
Authors: Bayandor Sara
Published: November 2022

Greenhouse gases, which mostly come from burning fossil fuels, are accumulating every day in the atmosphere and changing the climate around the world. New Zealand’s average annual temperature has risen by 1.13 degrees Celsius from 1909 to 2019 [1]. As a result, the level of sea is rising and adverse changes such as extreme rainfall, drought, increasing hunger and poor nutrition are beginning to emerge. Statistics show that the transport sector produces a considerable amount of carbon dioxide (CO2) annually. In New Zealand, road transport made up 43% of gross CO2 emission in 2018 and improving the engine technology was not effective [1]. Olivine is an easily accessible mineral that is found all over the earth’s mantle. Under natural conditions, 1 kg of Olivine can absorb about 1 kg of CO2 [2]. For optimal absorption, Olivine stone needs to be pulverised. Magnesium silicate in the stone reacts with water and CO2 to form bicarbonate that captures CO2 in a solid form. In addition to taking up CO2, Olivine has the potential to stabilise the soil sustainably through alkaline activation. New Zealand has 83,000 km of local roads and 11,000 km of state highways that have the potential to sequester CO2 not only in roads but also in the roadside area. Initial calculations show that the unsealed roads of New Zealand have the potential to absorb about 100,000 tonnes of CO2 annually. This study is a review paper that summarizes the recent progress in the field of sustainable roads. This presentation aims to evaluate the feasibility of using Olivine in road construction to stabilise the soil and calculate the potential of CO2 absorption in New Zealand to take a step toward the Climate Change Response (Zero-Carbon) Amendment Act 2019 and considerations concerning kaitiakitanga (guardianship).
Development of a digital gym instructor to improve movement patterns during gym-based exercises for women
Authors: Cuthbertson-Moon Melissa
Published: November 2022

In New Zealand the number of gym and fitness training related injuries dominate over every other sport. In 2020 it was reported they surpassed the number of claims for NZ’s national sport, rugby [1]. A recent Accident Compensation Corporation [ACC] report showed an 18% increase in gym injuries in the period between 2015-2020 with the cost of support rising by 43% [2].  An epidemiology analysis of 10 years of ACC injury data found that the exercises which led to the greatest number of injuries were the bench press, deadlift, and shoulder press [3]. The aim of this doctoral research is to trial the feasibility of a digital system to coach technique. We are recruiting 200 female inexperienced gym-users for an initial biomechanics screening using motion capture software to assess participants’ technique during bench press, deadlift, and shoulder press resistance exercises conducted using free weights, resistance machines and a TONAL strength training device.  A survey assessment will be carried out concurrently to understand the participants’ knowledge, attitudes, and behaviours (KAB) towards strength training and injury. Based on the biomechanics screening, 30 participants with poor technique will be identified and invited to participate in a 4-week study to understand the feasibility of a digital system to coach strength training and improve their technique. The knowledge gained in the study will enable education of gym users to prevent further injury via the ACC SportSmart program, with the potential to integrate digital gym instruction by development of a mobile application. In this poster presentation, I will present the findings of my epidemiology analysis and outline the practical aspects of the project, including the biomechanics screening, tools and follow-up study. There will be an opportunity for visitors to the symposium to find out more information about the study and express their interest to participate.
International multispecialty consensus on how to image, define, and grade ultrasound imaging features of first metatarsophalangeal joint osteoarthritis: A Delphi consensus study
Authors: Molyneux Prue
Published: November 2022

The objective of this research was to adopt a Delphi study design to reach consensus concerning which ultrasound imaging features should be assessed and graded, and what ultrasound imaging procedure should be performed when examining osteoarthritic change in the first metatarsophalangeal joint. An online Delphi study was conducted over four iterative rounds with 16 expert health professionals. Items were scored from 0-100 (0 = not at all important; 100 = extremely important). Consensus was defined based upon items receiving ≥70% of acceptance [1]. Items receiving ≤50% were rejected. Items considered ambiguous (median 51% - 69% of acceptance) were assessed in an additional round [2]. A final round determined the content validity of items through calculation of the content validity ratio and content validity index [3]. Sixteen items were deemed essential and seven items non-essential. Items deemed essential to assess included osteophytes graded dichotomously, cartilage damage graded continuously, synovitis and joint space narrowing graded on a semiquantitative scale. The panel deemed essential that the first metatarsophalangeal joint start in its neutral position then move through range of motion during scanning for both dorsal and plantar scan, orientating the probe in longitudinal and in transverse aspects, whilst using first metatarsal head and proximal phalanx as anatomical landmarks. A supine body position was only deemed essential for a dorsal scan and a neutral foot/ankle position was only rated essential for a plantar scan. The content validity index of the essential items was 0.19. The consensus exercise has identified essential components the ultrasound imaging acquisition procedure should encompass when examining first metatarsophalangeal joint osteoarthritis. The outcomes of the Delphi study will inform future studies into the methodological development of an ultrasound imaging atlas to grade the degree of osteoarthritic change in the first metatarsophalangeal joint.
