Improved estimates of extreme wave conditions in coastal areas from calibrated global reanalyses
Authors: Fanti Valeria , Ferreira Óscar , Kümmerer Vincent , Loureiro Carlos
Published: May 2023

The analysis of extreme wave conditions is crucial for understanding and mitigating coastal hazards. As global wave reanalyses allow to extend the evaluation of wave conditions to periods and locations not covered by in-situ measurements, their direct use is common. However, in coastal areas, the accuracy of global reanalyses is lower, particularly for extreme waves. Here we compare two leading global wave reanalyses against 326 coastal buoys, demonstrating that both reanalyses consistently underestimate significant wave height, 50-year return period and mean wave period in most coastal locations around the world. Different calibration methods applied to improve the modelled extreme waves, resulting in a 53% reduction in the underestimation of extreme wave heights. Importantly, the 50-year return period for significant wave height is improved on average by 55%. Extreme wave statistics determined for coastal areas directly from global wave reanalyses require careful consideration, with calibration largely reducing uncertainty and improving confidence.

Authors: Wang Haobo , Liu Yingxi , Ni Lei , Luo Ying
Published: May 2023

The micro‐Doppler (m‐D) effect caused by the rotational parts of the targets influences the quality of inverse synthetic aperture radar (ISAR) imaging. In this letter, a novel deep network‐assisted method is proposed to reduce the m‐D effect in ISAR imaging. The training data, including ISAR images with m‐D effect and ISAR images without m‐D effect, help the network establish non‐linear mapping relationships. The simulated and measured data results show the effectiveness of the proposed method.
Cascaded Temporal and Spatial Attention Network for solar adaptive optics image restoration
Authors: Zhang Chi , Wang Shuai , Zhong Libo , Chen Qingqing , Rao Changhui
Published: May 2023

Context.Atmospheric turbulence severely degrades the quality of images observed through a ground-based telescope. An adaptive optics (AO) system only partially improves the image quality by correcting certain level wavefronts, making post-facto image processing necessary. Several deep learning-based methods have recently been applied in solar AO image post-processing. However, further research is still needed to get better images while enhancing model robustness and using inter-frame and intra-frame information.

Aims.We propose an end-to-end network that can better handle solar adaptive image anisoplanatism by leveraging attention mechanisms, pixel-wise filters, and cascaded architecture.

Methods.We developed a cascaded attention-based deep neural network named Cascaded Temporal and Spatial Attention Network (CTSAN) for solar AO image restoration. CTSAN consists of four modules: optical flow estimation PWC-Net for inter-frame explicit alignment, temporal and spatial attention for dynamic feature fusion, temporal sharpness prior for sharp feature extraction, and encoder-decoder architecture for feature reconstruction. We also used a hard example mining strategy to create a loss function in order to focus on the regions that are difficult to restore, and a cascaded architecture to further improve model stability.

Results.CTSAN and the other two state-of-the-art (SOTA) supervised learning methods for solar AO image restoration are trained on real 705 nm photospheric and 656 nm chromospheric AO images supervised by corresponding Speckle images. Then all the methods are quantitatively and qualitatively evaluated on five real testing sets. Compared to the other two SOTA methods, CTSAN can restore clearer solar images, and shows better stability and generalization performance when restoring the lowest contrast AO image.
A rotational age for the open cluster NGC 2281
Authors: Fritzewski D. J. , Barnes S. A. , Weingrill J. , Granzer T. , Cole-Kodikara E. , Strassmeier K. G.
Published: May 2023

Context.Cool star rotation periods have become an important tool in determining ages of open clusters.

Aims.We aim to estimate the age of the open cluster NGC 2281 based on the rotational properties of its low-mass members. Previous age estimates for this open cluster range from 275 Myr to 630 Myr.

Methods.Based on an eight month-long photometric time series obtained at the 1.2 m robotic STELLA telescope in Tenerife, we measured rotation periods for 126 cool star members (70% of the observed members) of NGC 2281.

Results.The large set of rotation periods allows us to construct a rich colour-period diagram for NGC 2281 with very few outliers above the slow rotator sequence. We identify an evolved fast rotator sequence which can be used to accurately age date the open cluster relative to other open clusters. Comparisons with M 37 and M 48 show that all three open clusters are roughly coeval, and we estimate the age of NGC 2281 to be 435 ± 50 Myr. Through comparisons with the younger NGC 3532 and the older Praesepe, we determine the spin down rates of mid-K and early-M fast rotators to be significantly lower than for early-K stars. We suspect that the spin down of early-K fast rotators might be governed by an additional mass dependence.

Conclusions.Finally, we show the path towards an empirical description of the evolved fast rotator sequences in open clusters.
Spectral classification of young stars using conditional invertible neural networks
Authors: Kang Da Eun , Ksoll Victor F. , Itrich Dominika , Testi Leonardo , Klessen Ralf S. , Hennebelle Patrick , Molinari Sergio
Published: May 2023

Aims. We introduce a new deep-learning tool that estimates stellar parameters (e.g. effective temperature, surface gravity, and extinction) of young low-mass stars by coupling the Phoenix stellar atmosphere model with a conditional invertible neural network (cINN). Our networks allow us to infer the posterior distribution of each stellar parameter from the optical spectrum.

Methods. We discuss cINNs trained on three different Phoenix grids: Settl, NextGen, and Dusty. We evaluate the performance of these cINNs on unlearned Phoenix synthetic spectra and on the spectra of 36 class III template stars with well-characterised stellar parameters.

Results. We confirm that the cINNs estimate the considered stellar parameters almost perfectly when tested on unlearned Phoenix synthetic spectra. Applying our networks to class III stars, we find good agreement with deviations of 5–10% at most. The cINNs perform slightly better for earlier-type stars than for later-type stars such as late M-type stars, but we conclude that estimates of effective temperature and surface gravity are reliable for all spectral types within the training range of the network.

Conclusions. Our networks are time-efficient tools that are applicable to large numbers of observations. Among the three networks, we recommend using the cINN trained on the Settl library (Settl-Net) because it provides the best performance across the widest range of temperature and gravity.
A comparison study on methanol reforming catalysts for onboard hydrogen generation
Authors: Su Yanjing , Yu Jiao , Shen Jianyue
Published: May 2023

In hydrogen energy applications, methanol is the best fuel that can effectively solve the problem of the storage and transportation of hydrogen. The lowest reforming temperature among hydrocarbons also makes it the best fuel for hydrogen generation. This paper aimed to study and compare four methanolreforming catalysts and screen the best one suitable for the on-board hydrogen generation system. In this study, the in-house single-tube reactor, which can precisely control the temperature by a multistage heater, was applied to study the catalyst performance. Physical and chemical properties of the catalyst, such as methanol conversion rate, hydrogen generation rate, CO selectivity at a different liquid hourly space velocity (LHSV), catalyst density, and optimum reaction temperature, were also systematically studied. The hydrogen generation rate per unit mass of the WEF catalyst is the highest, which reached 0.122 g/h·gcat in 9.23 h-1 LHSV. And the methanol conversion rate in 7.72 h-1 LHSV is 96.74%, and somewhat below the BSF catalyst (97.90% in 7.55 h-1 LHSV). The study indicated that the catalyst made by WEF is the best catalyst for on-board hydrogen generation when comprehensively considering the requirement including the performance and vibration resistance. At the end of this paper, the optimized direction of the four catalyzers is also specified.

Authors: Zhang Ming , Zhao Junshan , Fang Zixuan , Wu Mengqiang
Published: May 2023

MnO2 is considered to be a prospective material for lithium-ion batteries anode. However, in practical applications, MnO2 has shortcomings such as low conductivity, large volume change and high charge transfer resistance, which seriously hinder its commercial application. In this work, MnO2 are preintercalated with various alkali cations (Na+, or NH4+) and coating with reduced graphene oxide through electrodeposition which designed for LIBs to improve its electrochemical behavior and understand the effect of cations and coating. It demonstrates that alkali cations can affect the growth morphology and electrochemical performance of MnO2, and graphene can improve electrical conductivity. Due to the advantages of its structure, MnO2&NH4+@rGO shows high capacity, rate performance (640 mAh g-1) and a long lifetime in lithium-ion batteries.
Übersetzung, kulturelle Adaptation und Test-Retest-Reliabilität der deutschen Version des Headache Disability Questionnaire
Authors: Ivanov Dimo , Ernst Markus J.
Published: May 2023

Einleitung Kopfschmerzen führen zu häufigen Einschränkungen im Alltag. Spezifische Fragebögen dienen als Messinstrumente zur Erfassung solcher kopfschmerzbedingten Einschränkungen. Im deutschsprachigen Raum besteht zurzeit kein ideales Messinstrument, das die Schwere der Einschränkung durch Kopfschmerzen innerhalb einer akzeptablen Recall-Zeit erfasst und zuverlässig misst. Der Headache Disability Questionnaire (HDQ) ist ein englischsprachiges Messinstrument, das die Anforderungen eines zuverlässigen Fragebogens für Kopfschmerzen erfüllt. Es besteht keine validierte deutsche Version des HDQ.

Ziel Übersetzung des HDQ in die deutsche Sprache, kulturübergreifende Adaption an die deutschsprachige Population sowie Untersuchung seiner Test-Retest-Reliabilität.

Methode Der HDQ wurde zuerst in einem 2-Phasen-Querschnittstudiendesign nach internationalen Richtlinien ins Deutsche übersetzt und adaptiert (HDQ-G). 12 erwachsene deutsche Muttersprachler*innen nahmen an kognitiven Interviews zur Verständlichkeit einer präfinalen deutschen Version des HDQ teil. Anschließend wurden Anpassungen in Absprache mit dem Erstautor der Originalversion und einem Expertenkomitee vorgenommen. Danach wurde die Test-Retest-Reliabilität des HDQ-G mittels Intraklassenkorrelationskoeffizienten (ICC) mithilfe von 29 erwachsenen Patient*innen mit Kopfschmerzen evaluiert und mittels Bland-Altman-Plot bildlich dargestellt. Die Teilnehmenden nahmen in einem Zeitraum von 2–14 Tagen je zweimal an einer Online-Umfrage mit der finalen Version teil.

Ergebnisse Alle Schritte des Übersetzungsprozesses wurden eingehalten und die finale deutsche Version des HDQ wurde mit wenigen Ergänzung fertiggestellt. Der HDQ-G zeigte eine sehr gute Test-Retest-Reliabilität mit einem ICC = 0,89 (95 %-Konfidenzintervall (KI) von 0,77–0,95). Die mittlere Differenz beider Umfragen lag bei + 1,72 Punkten, 95 % aller Werte lagen zwischen + 10,77 und -7,33 Punkten.

Schlussfolgerung Die originale Version des HDQ wurde übersetzt und für die Verwendung bei der erwachsenen deutschsprachigen Population im ambulanten physiotherapeutischen Setting adaptiert. Der HDQ-G zeigte eine sehr gute Test-Retest-Reliabilität und akzeptable Übereinstimmung bei allgemeinen Patient*innen mit Kopfschmerzen im physiotherapeutischen Setting. Zusätzliche Studien sind notwendig, um weitere wissenschaftliche Gütekriterien des HDQ zu untersuchen.

Authors: Lopez Christopher D. , Yusuf Cynthia T. , Girard Alisa O. , Lake Isabel V. , Cooney Damon S. , Redett Richard J.
Published: May 2023

Background It can be argued that individuals in the transgender and gender nonbinary (TGNB) community suffer from a similar impact on quality of life in the face of gender dysphoria, with psychosocial and physical consequences. Indications for penile allotransplantation for patients wishing to undergo gender affirmation surgery have yet to be elucidated, but technical lessons for feasibility can be gleaned from penis transplants that have already been performed on cisgender males to date.

Methods This study investigates the theoretical feasibility for penile-to-clitoral transplantation, prior penile transplants, and current multidisciplinary gender affirmation health care modalities.

Results Penile allotransplantation offers a potential solution for individuals in the TGNB community for a more aesthetic penis, improved erectile function without the need of a prosthesis, optimal somatic sensation, and improved urethral outcomes.

Conclusion Questions remain about ethics, patient eligibility, and immunosuppressive sequelae. Before these issues are addressed, feasibility of this procedure must be established.
Clinical Outcomes of Offset Stem Couplers with or without Cone Augmentation in Revision Total Knee Arthroplasty
Authors: Fiedler Benjamin , Bieganowski Thomas , Singh Vivek , Marwin Scott , Rozell Joshua C. , Schwarzkopf Ran
Published: May 2023

Intramedullary stems are often required in patients undergoing revision total knee arthroplasty (rTKA) to achieve stable fixation. Significant bone loss may require the addition of a metal cone to maximize fixation and osteointegration. The purpose of this study was to investigate clinical outcomes in rTKA using different fixation techniques. We conducted a single-institution retrospective review of all patients who received a tibial and femoral stem during rTKA between August 2011 and July 2021. Patients were separated into three cohorts based on fixation construct: press-fit stem with an offset coupler (OS), fully cemented straight (CS) stem, and press-fit straight (PFS) stem. A subanalysis of patients who received tibial cone augmentation was also conducted. A total of 358 patients who underwent rTKA were included in this study, of which 102 (28.5%) had a minimum 2-year follow-up and 25 (7.0%) had a minimum 5-year follow-up. In the primary analysis, 194 patients were included in the OS cohort, 72 in the CS cohort, and 92 in the PFS cohort. When stem type alone was considered, there was no significant difference in rerevision rate (p = 0.431) between cohorts. Subanalysis of patients who received augmentation with a tibial cone demonstrated that OS implants led to significantly higher rates of rerevision compared with the other two stem types (OS: 18.2% vs. CS: 2.1% vs. PFS: 11.1%; p = 0.037). The findings of the present analysis demonstrate that CS and cones in rTKA may provide more reliable long-term outcomes compared with press-fit stems with OS.

Published: May 2023

Bladder cancer (BCa) is a leading cause of cancer worldwide with high incidence and mortality across all ages. Early diagnosis and treatment can lead to significantly improved survival rate and overall prognosis. Smoking is the biggest contributing factor for the development of BCa. Urothelial carcinoma is the most common histological subtype. Commonly implemented imaging techniques include computed tomography urography (CTU) and multiparametric magnetic resonance imaging (mpMRI). CTU is the investigation of choice for muscle invasive bladder cancer (MIBC) and is best utilized for local assessment and staging of larger and higher staged tumors, that is, T3b and T4. mpMRI encompasses T2-weighted imaging, diffusion-weighted imaging, and dynamic contrast-enhanced imaging. It can differentiate ≤T1 and ≥T2 tumors based on the Vesicle Imaging-Reporting and Data System (VI-RADS) assessment as well as differentiate Ta from T1 tumors, and is useful in post-therapy response assessment of BCa. Positron emission tomography/computed tomography is used in selected patients of MIBC for metastatic evaluation, particularly those with deranged renal function. A synoptic reporting template should be used to have standardization of data. Primary urethral cancer (UCa) is a rare and aggressive malignancy, accounting for less than 1% of all malignancies. MRI is the investigation of choice for UCa.

Thyroid cancer ranks as the leading endocrine malignancy in adults. The foundation for primary diagnosis of thyroid cancer is a high-resolution ultrasound (US) of the thyroid gland including US-guided fine-needle biopsy (FNB) of suspected thyroid nodules. Advanced cross-sectional imaging, including computed tomography (CT), magnetic resonance imaging, and positron emission tomography, can be useful in selected patients. The mainstay of treatment of thyroid cancer is surgery. It may be supplemented by radioactive iodine ablation/therapy in high-risk differentiated thyroid cancer. Radiology plays a crucial role in both diagnostic and posttreatment follow-up imaging. Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder with single parathyroid adenoma being its most common cause. The radiologist's aim in parathyroid imaging is to provide the clinician with an illustrative picture of the neck, locating lesions with respect to landmarks. Imaging helps in the detection of solitary versus multiglandular disease, ectopic and supernumerary glands with precise localization. US, nuclear imaging, and four-dimensional CT are the most commonly used imaging modalities for the preoperative localization of the parathyroid disease. Salivary gland tumors account for approximately 0.5% of all neoplasms, the most common location being the parotid gland (70%). Imaging is crucial in salivary gland tumors by defining its location, detecting malignant features, assessing local extension and invasion, staging the tumors according to the tumor-node-metastasis classification, and assessing the feasibility of surgery.

The History of the Transjugular Intrahepatic Portosystemic Shunt
Authors: Ferral Hector , Lopez-Benitez Ruben
Published: May 2023

Few, if any, developments in the past three decades have advanced the field of portal hypertension more than the use of transjugular intrahepatic portosystemic shunts (TIPS). Initially pursued in animal studies more than 50 years ago, and discovered serendipitously, TIPS quickly became used clinically in the treatment of refractory esophageal hemorrhage. The technique is now used for many other clinical indications as well as to bridge patients to liver transplantation. Several technical advancements have improved short- and long-term outcomes of the procedure. This article will review the development of TIPS from its inception to the current state of care regarding this important minimally invasive option for patients with portal hypertension.

Published: May 2023

Transjugular intrahepatic portosystemic shunt (TIPS) creation treats complications of portal hypertension in appropriately selected patients by lowering the portal venous pressure. While this can be a lifesaving intervention, portal venous flow diversion is not without potential consequences. Overshunting can lead to hepatic decompensation and encephalopathy. TIPS reduction and TIPS occlusion are therapeutic options used to mitigate overshunting, with reduction being the initial alternative due to retained shunt patency and lower potential for venous thrombosis. Patient selection, techniques for TIPS reduction, and patient outcomes are reviewed in this article.

Published: May 2023

Portal vein thrombosis (PVT) is a heterogeneous condition with multiple possible etiologies and to varying degrees has historically limited candidacy for liver transplant (LT) in the cirrhotic patient population due to resultant difficulties in constructing a robust portal vein anastomosis. While intraoperative approaches to managing PVT are well-described, methods which approximate normal portal physiology are not always feasible depending on the extent of PVT, and other nonphysiologic techniques are linked with substantial morbidity and poor long-term outcomes. Portal vein recanalization–transjugular intrahepatic portosystemic shunt (PVR-TIPS) creation is an efficacious method of restoring physiologic portal flow in cirrhotic patients prior to LT allowing for end-to-end PV anastomosis, and is the product of decades-long institutional expertise in TIPS/LT and the support of a multidisciplinary liver tumor board. To follow is a review of the pertinent pathophysiology of PVT in cirrhosis, the rationale leading to the development and subsequent evolution of the PVR-TIPS procedure, technical lessons learned, and a summary of outcomes to date.
Advanced Techniques for Accessing the Portal Vein during Transjugular Intrahepatic Portosystemic Shunt Creation

Published: May 2023

Transjugular portosystemic shunt (TIPS) placement is a widely accepted method for reducing portal pressures in conditions including symptomatic varices, refractory ascites, hepatic hydrothorax, portomesenteric thrombosis, and Budd-Chiari syndrome. The traditional method for performing TIPS involves “blind” access into a portal vein branch from a hepatic vein, typically right portal vein to right hepatic vein, using preoperative imaging and intraoperative wedged portography for guidance. However, standard access technique may not always be feasible due to occluded portal or hepatic veins, distorted anatomy, or prior TIPS. In this article we discuss alternative techniques for accessing the portal vein for TIPS placement when standard methods are not sufficient.

Published: May 2023

Objectives The aim of this study was to define landmarks of the intermetatarsal channel of the dorsal pedal artery and to assess whether damage to the dorsal pedal artery during metatarsal screw placement in dogs undergoing pan- and partial-tarsal arthrodesis (PanTA/ParTA) could be a mechanism in the development of plantar necrosis.

Study Design This study was divided in to two parts: (1) ex-vivo anatomical study: 19 canine cadavers, (2) retrospective clinical study: 39 dogs. Cadaveric dissection documented the mean intermetatarsal channel position. Metatarsal screw position was evaluated on postoperative radiographs of dogs after PanTA or ParTA. Screw position, arthrodesis type and surgical approach were assessed for their impact on complications, including plantar necrosis.

Results The mean proximal and distal extent of the intermetatarsal channel lies between 4.3% ± 1.9 and 22.8% ± 2.9 the length of metatarsal III (MTIII) respectively. The intermetatarsal channel lies within the most proximal 25% of MTIII in 95% of cases. At least one screw risked damaging the mean intermetatarsal channel position in 92% of dogs; 8% of these dogs went on to develop plantar necrosis. The mean screw position did not differ between ParTA cases with or without plantar necrosis (p > 0.05).

Conclusion Violation of the intermetatarsal channel is possible during metatarsal screw placement. Care should be taken when placing screws in the proximal 25% of the metatarsals, specifically avoiding exiting dorsally between MTII and MTIII and across the distal region of the intermetatarsal channel, where the perforating metatarsal artery passes interosseously, as damage may contribute to the aetiology of plantar necrosis.

Published: May 2023

Micromagnetic simulation is a numerical method to solve the Landau–Lifshitz–Gilbert (LLG) equation for magnetic dynamics. Most of the mainstream micromagnetic simulation packages, including the object oriented micromagnetic framework and MuMax3, perform simulation in the time domain. Here, utilizing the frequency domain simulation capability of COMSOL Multiphysics, we developed a COMSOL-based micromagnetic simulation module that solves the LLG equation in the frequency domain, which runs much faster and more accurate than time-domain simulations. Frequency-domain simulation is ideal for finding spin wave eigenmodes and the corresponding dispersions. We verify the validity of the module using three examples in the absence of dipolar field, and the inclusion of the dipolar field can be incorporated by combining this module with the alternating current/direct current module within COMSOL.

We present a broadly applicable in situ method for profiling ion beams using electrostatic deflectors and a Faraday cup. By deconvolving the detector geometry from the resulting current profiles, spatially resolved absolute current density profiles are obtained. We demonstrate this method’s efficacy with low-density highly charged ion beams (specifically, Ne8+). Details on experimental design are provided as well as the link to the deconvolution routine on GitHub.

Tuning the properties of magnetic materials by voltage-driven ion migration (magneto-ionics) gives potential for energy-efficient, non-volatile magnetic memory and neuromorphic computing. Here, we report large changes in the magnetic moment at saturation (mS) and coercivity (HC), of 34% and 78%, respectively, in an array of CoFe2O4 (CFO) epitaxial nanopillar electrodes (∼50 nm diameter, ∼70 nm pitch, and 90 nm in height) with an applied voltage of −10 V in a liquid electrolyte cell. Furthermore, a magneto-ionic response faster than 3 s and endurance >2000 cycles are demonstrated. The response time is faster than for other magneto-ionic films of similar thickness, and cyclability is around two orders of magnitude higher than for other oxygen magneto-ionic systems. Using a range of characterization techniques, magnetic switching is shown to arise from the modulation of oxygen content in the CFO. Also, the highly cyclable, self-assembled nanopillar structures were demonstrated to emulate various synaptic behaviors, exhibiting non-volatile, multilevel magnetic states for analog computing and high-density storage. Overall, CFO nanopillar arrays offer the potential to be used as interconnected synapses for advanced neuromorphic computing applications.

Objective To estimate the risk of an emergency department (ED)/inpatient visit due to complications in people with diabetes and compare them to their non-diabetes counterparts. Methods This matched retrospective cohort study used a linked dataset in Tasmania, Australia for the 2004–17 period. People with diabetes (n = 45 378) were matched on age, sex and geographical regions with people without diabetes (n = 90 756) based on propensity score matching. The risk of an ED/inpatient visit related to each complication was estimated using negative binomial regression. Results In people with diabetes, the combined ED and admission rates per 10 000 person-years were considerable, especially for macrovascular complications (ranging from 31.8 (lower extremity amputation) to 205.2 (heart failure)). The adjusted incidence rate ratios of ED/inpatient visits were: retinopathy 59.1 (confidence interval 25.8, 135.7), lower extremity amputation 11.1 (8.8, 14.1), foot ulcer/gangrene 9.5 (8.1, 11.2), nephropathy 7.4 (5.4, 10.1), dialysis 6.5 (3.8, 10.9), transplant 6.3 (2.2, 17.8), vitreous haemorrhage 6.0 (3.7, 9.8), fatal myocardial infarction 3.4 (2.3, 5.1), kidney failure 3.3 (2.3, 4.5), heart failure 2.9 (2.7, 3.1), angina pectoris 2.1 (2.0, 2.3), ischaemic heart disease 2.1 (1.9, 2.3), neuropathy 1.9 (1.7, 2.0), non-fatal myocardial infarction 1.7 (1.6, 1.8), blindness/low vision 1.4 (0.8, 2.5), non-fatal stroke 1.4 (1.3, 1.6), fatal stroke 1.3 (0.9, 2.1) and transient ischaemic attack 1.1 (1.0, 1.2). Conclusions Our results demonstrated the high demand on hospital services due to diabetes complications (especially macrovascular complications) and highlighted the importance of preventing and properly managing microvascular complications. These findings will support future resource allocation to reduce the increasing burden of diabetes in Australia.
