Comparison of two endoscope channel cleaning approaches to remove cyclic build-up biofilm.

INTRODUCTION: Biofilm contributes significantly to bacterial persistence in endoscope channels. Enhanced cleaning methods capable of removing biofilm from all endoscope channels are required to decrease infection risk to patients. This head-to-head study compared cyclic build-up biofilm removal of an automated endoscope channel cleaner (AECC) with standard manual cleaning according to instructions for use (IFU) in polytetrafluorethylene channels. METHODS: Cyclic build-up biofilm was grown in 1.4-mm (representing air/water and auxiliary channels) and 3.7-mm (representing suction/ biopsy channels) inner diameter polytetrafluorethylene channels. All channels were tested for residual total organic carbon, protein, and viable bacteria. Internationally recognized ISO 15883-5:2021 alert levels were used as cleaning benchmarks for protein (3 µg/cm2) and total organic carbon (6 µg/cm2). RESULTS: The automated cleaner significantly outperformed manual cleaning for all markers assessed (protein, total organic carbon, viable bacteria) in 1.4-mm and 3.7-mm channels representing air/water/auxiliary and suction/biopsy channels, respectively. Manual cleaning failed to remove biofilm from the air/water and auxiliary channels. According to the IFU, these channels are not brushed, suggesting a potential root cause for a portion of the numerous endoscopy-associated infections reported in the literature. CONCLUSION: AECC shows potential to deliver enhanced cleaning over current practice to all endoscope channels and may thereby address infection risk.

Indian Perspective on De-escalation from Dual Antiplatelet Therapy to Single Antiplatelet Therapy Study: A Knowledge, Attitude, and Practice Study among Indian Interventional Cardiologists.

BACKGROUND: Coronary artery disease (CAD) management is one of the most significant facets of interventional cardiology. Evidence from several clinical trials has redefined the drug management of CAD, including optimizing the duration of antiplatelet treatment regimens in the management of CAD, which is an intricate clinical issue. The available evidence indicates that East Asians have a higher bleeding risk. However, the Indian phenotype differs from that of East Asians, making this data confounding when applied to clinical decision-making among Indian patients. There is a need for a close understanding of Indian interventional cardiologists' perceptions of complex decision-making pertaining to antiplatelet agents among Indian CAD patients in real-world clinical settings. AIM: This Indian Perspective on De-escalation from Dual Antiplatelet Therapy to Single Antiplatelet Therapy (INDEPTH) study aims to assess the perspective of Indian interventional cardiologists regarding de-escalating from dual antiplatelet therapy (DAPT) to single antiplatelet therapy (SAPT), approach to decision-making, barriers, and related challenges in CAD management. METHODS: A cross-sectional knowledge, attitude, and practice (KAP) study survey was carried out among Indian interventional cardiologists practicing across different regions of India. A total of 209 responses were received. Descriptive statistics was used to summarize all the parameters. IBM Statistical Package for the Social Sciences (SPSS) statistics was used for biostatistical analysis. RESULTS: The study indicated that >90% of CAD patients received DAPT therapy immediately after percutaneous coronary intervention (PCI) (86.1%, p < 0.001). About 115 (55%) of the respondents reported using calculator-based scoring for evaluating bleeding risk in patients on DAPT therapy for the management of acute coronary syndrome (ACS) with post-PCI (p = 0.167). Regarding the usual duration of DAPT therapy post-ACS, nearly half of the respondents, 94 (45%), said that 6-12 months is the usual duration for DAPT therapy in post-ACS patients, followed by > 12 months 94 (45%) of the respondents; 17 (8.1%) of the respondents reported it is 3-6 months, and lastly up to 3 months as per four (1.9%) of the respondents (p < 0.001). A total of 128 (61%) of the respondents strongly believe that balancing bleeding with ischemic risk influenced the choice of antiplatelet agent when treating established CAD. As per interventional cardiologists surveyed, the perfect de-escalation time frame for Indian CAD patients with high bleeding risk (HBR) is up to 3 months (35.9%, p < 0.001), 6-12 months for medium bleeding risk (48.8%, p < 0.001), and >12 months for low bleeding risk (65.6%, p < 0.001). Regarding SAPT therapy, almost one-third of the respondents, 65 (31.1%), reported that they prescribed antiplatelet therapy other than aspirin in 20-40% of their SAPT-eligible patients. Furthermore, 69 (33%) of the respondents said that they preferred to prescribe clopidogrel in 50-75% of SAPT-eligible patients. While 64 (30.5%) prescribed in 25-50%, 53 (25.4%) prescribed in <25% and 23 (11%) of the respondents prescribed the drug in >75% of the SAPT-eligible patients. (p < 0.001). "Atorvastatin + clopidogrel" is the most preferred combination of SAPT primarily for the management of CAD among the majority of interventional cardiologists [33%, 95% confidence interval (CI): 1.97-2.24, p < 0.001]. The study respondents also indicated a need for Indian-specific guidelines on de-escalating from DAPT to SAPT in CAD management. CONCLUSION: The INDEPTH study indicated that the majority of CAD patients received DAPT immediately after PCI. The perfect de-escalation time frame for Indian CAD patients with "high-bleeding" risk is up to 3 and 6-12 months for "medium-bleeding" risk and >12 months for "low-bleeding" risk. One-third of respondents used clopidogrel as an antiplatelet agent in 50-75% of SAPT-eligible patients. Atorvastatin + clopidogrel is predominantly the most preferred combination of statin + SAPT for the management of CAD. Although the current international guidelines cover the Indian perspective to some extent, there is a need for Indian-specific guidelines on de-escalating from DAPT to SAPT.

Evaluation of the reach and impact of a UK campaign highlighting obesity as a cause of cancer among the general public and Members of Parliament.

OBJECTIVES: 'Overweight and obesity' is the second biggest preventable cause of cancer after smoking. In 2018, Cancer Research UK launched an awareness raising campaign about the link between overweight and obesity and cancer risk. This study aimed to evaluate the reach and impact of the campaign. STUDY DESIGN: This study was a repeated cross-sectional online survey. METHODS: The campaign consisted of six elements including the main message that 'Obesity is a cause of cancer'. UK adults and Members of Parliament (MPs) were surveyed before the campaign (W1; n = 2124 and n = 151), 1 month (W2; n = 2050 and n = 151) and 3 months after the campaign (W3; n = 2059 and MPs not surveyed). Outcome measures were campaign reach, awareness of overweight and obesity as risk factors for cancer, attitudes towards individuals who are overweight or obese, support for policies to reduce obesity and reactions to the campaign. RESULTS: Overall, 76.2% of MPs and just under half of the public (47.5% in W2 and 36.8% in W3) reported having seen the campaign. Unprompted awareness of obesity as a risk factor increased among the public from 17.1% at W1 to 43.3% in W2 (odds ratio 3.71, 95% confidence interval 3.18-4.33) and 30.3% in W3 (odds ratio 2.11, 95% confidence interval 1.80-2.47). A similar pattern was seen for prompted awareness and among MPs. There were no consistent changes in attitudes towards overweight individuals or support for policies to reduce obesity. CONCLUSIONS: This evaluation suggests that the campaign achieved the primary objective of increasing awareness of the link between obesity and cancer without increasing negative attitudes towards individuals who are overweight or obese.

LTSI Consensus Guidelines: Preoperative Pulmonary Evaluation in Adult Liver Transplant Recipients.

The relationship between chronic liver disease and respiratory symptoms and hypoxia is well recognized. Over the last century, three pulmonary complications specific to chronic liver disease (CLD) have been characterized: hepatopulmonary syndrome, portopulmonary hypertension, and hepatic hydrothorax. Apart from that coexisting pulmonary disease like chronic obstructive lung disease and interstitial lung disease also complicate the outcomes after liver transplantation (LT). Assessment for evaluation of underlying pulmonary disorders is essential to improve outcomes in patients with CLD, posted for LT. This consensus guideline of the Liver Transplant Society of India (LTSI) provides a comprehensive review of pulmonary issues in CLD, related and unrelated to underlying liver disease and gives recommendations for pulmonary screening in specific clinical scenarios in adults with chronic liver disease planned for LT. This document also aims to standardize the strategies for preoperative evaluation of these pulmonary issues in this subset of patients. Proposed recommendations were based on selected single case reports, small series, registries, databases, and expert opinion. The paucity of randomized, controlled trials in either of these disorders was noted. Additionally, this review will highlight the lacunae in our current evaluation strategy, challenges faced, and will provide direction to potentially useful futuristic preoperative evaluation strategies.

Clinical Decision Pathway for the Use of Fondaparinux in the Management of Acute Coronary Syndrome (ACS) in Hospitals with and Without Catheter Laboratories: An Expert Opinion from India.

The current recommendations by Indian experts who are focused on the challenges in the management of patients with acute coronary syndrome (ACS) in rural areas, due to limited catheterization (CATH) lab facilities and interventional cardiologist coverage across the country, are described. 120 cardiologist experts drafted recommendations during ten advisory board meetings conducted from April to May 2022. Experts framed statements based on experience, collective clinical judgment from practical experience, and available scientific evidence regarding ACS. The consensus positioned fondaparinux as highly useful in non-CATH-lab-based hospitals for patients diagnosed with non-ST elevation acute coronary syndrome (NSTE-ACS) and ST elevation acute coronary syndrome (STE-ACS) patients who cannot be shifted to percutaneous coronary intervention (PCI)-capable centres, or for patients who are thrombolysed at peripheral centres.

Common Neuroimaging Findings in Bosch-Boonstra-Schaaf Optic Atrophy Syndrome.

Bosch-Boonstra-Schaaf optic atrophy syndrome (BBSOAS) is a rare autosomal dominant syndrome secondary to mutations in NR2F1 (COUP-TF1), characterized by visual impairment secondary to optic nerve hypoplasia and/or atrophy, developmental and cognitive delay, and seizures. This study reports common neuroimaging findings in a cohort of 21 individuals with BBSOAS that collectively suggest the diagnosis. These include mesial temporal dysgyria, perisylvian dysgyria, posterior predominant white matter volume loss, callosal abnormalities, lacrimal gland abnormalities, and optic nerve volume loss.

A critical appraisal of clinical practice guidelines for the diagnosis and management of benign paroxysmal positional vertigo.

BACKGROUND: Delays in the diagnosis and therapy of benign paroxysmal positional vertigo can greatly impact quality of life and increase healthcare costs for patients. This study aimed to appraise the quality of clinical practice guidelines for the diagnosis and management of benign paroxysmal positional vertigo. METHODS: A comprehensive database search of clinical practice guidelines was completed up to 30 October 2021. Four independent reviewers used the Appraisal of Guidelines for Research and Evaluation II instrument in the quality appraisal. RESULTS: The highest score was in 'clarity and presentation' (58.33 ± 22.7). The lowest score was in 'applicability' (13.96 ± 30.1). Overall, four clinical practice guidelines were 'low quality' and only one guideline was 'high quality'. CONCLUSION: This review identified a significant lack of quality in clinical practice guideline development for benign paroxysmal positional vertigo, highlighting the need for a more rigorous approach for future guideline development.

Isolated bilateral lateral geniculate body necrosis following acute pancreatitis: A rare cause of bilateral loss of vision in a young female.

Sudden bilateral visual loss because of bilateral lateral geniculate body (LGB) necrosis is a very rare entity. The mechanisms causing these isolated lesions have still not been fully understood. We report a case of sudden loss of vision in a 22-year-old female following an attack of acute pancreatitis, just after starting the paleo diet. Neuroimaging revealed bilateral LGB necrosis. Multidisciplinary approach was sought and she was subsequently managed successfully. On follow-up, her visual acuity showed improvement, and neuroimaging revealed resolution of hyperintensities in bilateral LGB with residual blooming suggestive of old hemorrhagic gliosis. The possible reasons for isolated lesions of the LGB are hemorrhagic infarction and osmotic demyelination. In the present case, we postulate a vascular pathology, possibly hypo-perfusion because of shock following acute pancreatitis.

Design, Synthesis, SAR, Pharmacokinetic Prediction of New 4-Quinolones as Anti-Microbial Agents.

s of new 4-quinolone derivatives was synthesized by conventional heating method. For the synthesized compounds, we performed pharmacokinetic prediction, SAR and antimicrobial assay. The presence of halogen elements plays a key role in the biological activity that is clear by in vitro analysis. Target compounds exhibit moderate to significant activity near to standard marketed drugs like amoxycillin, chloramphenicol, ciprofloxacin, norfloxacin, griseofulvin, and nystatin.

Factors influencing treatment outcomes in patients with isoniazid-resistant pulmonary TB.

INTRODUCTION: Patients with isoniazid (H, INH) resistant pulmonary TB but undetected rifampicin (R, RIF) resistance are treated with a 6-month regimen of levofloxacin-RIF-ethambutol-pyrazinamide (6LvxREZ) under India´s National TB Elimination Programme (NTEP).OBJECTIVE: To describe the profile of and treatment outcomes in patients with pulmonary INH-resistant (INHR) TB initiated on TB treatment, and identify factors associated with unfavourable treatment outcomes (died, failed, treatment changed, lost to follow-up).METHODS: This was a retrospective analysis of NTEP database (Ni-kshay) on pulmonary INHR TB patients initiated on treatment with "H mono/poly regimen" (6LvxREZ) between July 2019 and June 2020 with documented treatment outcomes. Proportions with 95% confidence interval (CI) was calculated and logistic regression analysis was performed.RESULTS: Of the 11,519 patients with pulmonary INHR TB, 9,440 (82%) had treatment success (55.1% cured, 26.9% treatment completed). Unfavourable treatment outcome was observed in 1,901 (16.5%). Male sex, tobacco and alcohol use, HIV reactive status were associated with unfavourable treatment outcome. Patients with katG mutations and resistance to fluoroquinolones were likely to have poor treatment outcomes.CONCLUSION: A levofloxacin-based regimen offers a treatment success rate of 82% in patients with pulmonary INHR TB. Sex-specific strategies, interventions to address smoking and alcohol use, focus on HIV-reactive patients and optimising treatment regimens based on drug susceptibility should be considered for improving treatment outcomes.

Resisted Inspiration: A New Technique to Aid in the Detection of CSF-Venous Fistulas.

We describe a technique termed "resisted inspiration" that could be used during myelography to decrease superior vena cava venous pressure and increase lumbar CSF pressure, potentially aiding in the detection of CSF-venous fistulas.

The MELD Score Is Superior to the Maddrey Discriminant Function Score to Predict Short-Term Mortality in Alcohol-Associated Hepatitis: A Global Study.

INTRODUCTION: Several scoring systems predict mortality in alcohol-associated hepatitis (AH), including the Maddrey discriminant function (mDF) and model for end-stage liver disease (MELD) score developed in the United States, Glasgow alcoholic hepatitis score in the United Kingdom, and age, bilirubin, international normalized ratio, and creatinine score in Spain. To date, no global studies have examined the utility of these scores, nor has the MELD-sodium been evaluated for outcome prediction in AH. In this study, we assessed the accuracy of different scores to predict short-term mortality in AH and investigated additional factors to improve mortality prediction. METHODS: Patients admitted to hospital with a definite or probable AH were recruited by 85 tertiary centers in 11 countries and across 3 continents. Baseline demographic and laboratory variables were obtained. The primary outcome was all-cause mortality at 28 and 90 days. RESULTS: In total, 3,101 patients were eligible for inclusion. After exclusions (n = 520), 2,581 patients were enrolled (74.4% male, median age 48 years, interquartile range 40.9-55.0 years). The median MELD score was 23.5 (interquartile range 20.5-27.8). Mortality at 28 and 90 days was 20% and 30.9%, respectively. The area under the receiver operating characteristic curve for 28-day mortality ranged from 0.776 for MELD-sodium to 0.701 for mDF, and for 90-day mortality, it ranged from 0.773 for MELD to 0.709 for mDF. The area under the receiver operating characteristic curve for mDF to predict death was significantly lower than all other scores. Age added to MELD obtained only a small improvement of AUC. DISCUSSION: These results suggest that the mDF score should no longer be used to assess AH's prognosis. The MELD score has the best performance in predicting short-term mortality.

The impact of outdoor walking surfaces on lower-limb coordination and variability during gait in healthy adults.

BACKGROUND: Inter-joint coordination and variability during gait provide insight into control and adaptability of the neuromuscular system. To date, coordination research has been restricted to laboratory settings, and it is unclear how these findings translate to real-world, outdoor walking environments. RESEARCH QUESTION: Compared to flat walking, to what extent do outdoor surfaces impact lower-limb inter-joint coordination and variability during gait, in healthy adults? METHODS: Data from inertial measurement units placed on the lower-back, thigh, and shank were extracted from thirty healthy young adults (15 females, 23.5 ± 4.2 years) during outdoor walking on flat (paved sidewalk); irregular (cobblestone, grass); sloped (slope-up, slope-down); and banked (banked-right, banked-left) surfaces. Sagittal joint angles for the right knee and hip were computed and partitioned by gait phase (stance and swing). Continuous Relative Phase analysis determined inter-joint coordination and variability for the knee-hip joint pair using Mean Absolute Relative Phase (MARP) and Deviation Phase (DP), respectively. One-way repeated measures ANOVAs tested surface effects. Post-hoc Bonferroni adjusted surface comparisons were assessed. RESULTS: Significant knee-hip surface effects were seen during all gait phases for MARP (p < 0.001) and DP (p ≤ 0.001). Compared to flat walking, grass prompted more in-phase coordination (smaller MARP) during stance and swing phase (p ≤ 0.003). Slope-up caused more in-phase coordination during stance (p < 0.001), while slope-down caused more out-of-phase coordination during stance and swing (p ≤ 0.003), compared to the flat surface. Sloped surfaces prompted more variable (larger DP) knee-hip coordination (p ≤ 0.001), compared to flat walking during stance and swing phase. SIGNIFICANCE: Compared to flat walking, changes in knee-hip coordination and variability were greatest on slope-up/slope-down surfaces. This could reflect greater changes in lower-limb kinematics on sloped surfaces and/or a neuromuscular response to the demands of a more challenging task.

Challenges in LTBI care in the United States identified using a nationwide TB medical consultation database.

BACKGROUND: Identifying and treating individuals with latent TB infection (LTBI) represents a critical and challenging component of national TB elimination. Medical consultations by the Centers for Disease Control and Prevention (CDC) funded TB Centers of Excellence (COEs) are an important resource for healthcare professionals (HCPs) caring for individuals with LTBI. This study aimed to identify the most common clinical concerns regarding LTBI care and to describe epidemiologic and clinical features of patients discussed in these consultations. METHODS: This mixed-methods study randomly sampled 125 consultation inquiries related to LTBI from the COEs' medical consultation database in 2018. Text from consultation records were reviewed and coded to identify reasons for the inquiries and common epidemiologic and clinical patient characteristics. RESULTS: The most common topics of inquiry for consultation included accurate LTBI diagnosis (36%), management of LTBI treatment-related issues (22%), and choice of appropriate LTBI treatment regimen (17%). Patients for whom consultations were requested commonly had another medical condition (34%), were non-U.S. born (31%), were children (25%), and had a history of travel to TB-endemic areas (18%). CONCLUSION: Our findings emphasize the challenge of managing patients with either suspected or confirmed LTBI, highlighting the need for ongoing medical consultation support for nuanced clinical and epidemiologic scenarios.

CONTEXTE: L'identification et le traitement des personnes atteintes d'infection tuberculeuse latente (LTBI) sont des composantes essentielles et difficiles de la stratégie nationale d'élimination de la TB. Les consultations médicales des TB Centers of Excellence (COE), financés par les Centres pour le contrôle et la prévention des maladies (CDC), sont d'importantes ressources pour les professionnels de santé qui prennent en charge les personnes atteintes de LTBI. Cette étude avait pour objectif d'identifier les problèmes cliniques les plus fréquents en matière de prise en charge de la LTBI, et de décrire les caractéristiques épidémiologiques et cliniques des patients évoquées lors de ces consultations. MÉTHODES: Cette étude à méthodes mixtes a sélectionné de manière aléatoire 125 demandes de consultations relatives à la LTBI à partir de la base de données des consultations médicales du COE en 2018. Les notes des dossiers de consultation ont été revues et codées pour identifier les raisons des demandes, ainsi que les caractéristiques cliniques et épidémiologiques fréquentes des patients. RÉSULTATS: Les raisons les plus fréquentes de demandes de consultation étaient diagnostic précis de LTBI (36%), prise en charge des problèmes liés au traitement de la LTBI (22%) et choix d'un schéma thérapeutique approprié de la LTBI (17%). Les patients pour lesquels des consultations étaient demandées avaient fréquemment une autre pathologie (34%), n'étaient pas nés aux États-Unis (31%), étaient des enfants (25%) et avaient des antécédents de voyage dans des zones où la TB est endémique (18%). CONCLUSION: Nos résultats mettent l'accent sur les défis de la prise en charge des patients avec une LTBI présumée ou confirmée, soulignant le besoin d'aide continue aux consultations médicales pour des scénarios épidémiologiques et cliniques nuancés.

Spinal Compliance Curves: Preliminary Experience with a New Tool for Evaluating Suspected CSF Venous Fistulas on CT Myelography in Patients with Spontaneous Intracranial Hypotension.

BACKGROUND AND PURPOSE: Craniospinal space compliance reflects the distensibility of the spinal and intracranial CSF spaces as a system. Craniospinal space compliance has been studied in intracranial pathologies, but data are limited in assessing it in spinal CSF leak. This study describes a method to estimate craniospinal space compliance using saline infusion during CT myelography and explores the use of craniospinal space compliance and pressure-volume curves in patients with suspected cerebrospinal-venous fistula. MATERIALS AND METHODS: Patients with suspected cerebrospinal-venous fistula underwent dynamic CT myelography. During the procedure, 1- to 5-mL boluses of saline were infused, and incremental changes in CSF pressure were recorded. These data were used to plot craniospinal space compliance curves. We calculated 3 quantitative craniospinal space compliance parameters: overall compliance, compliance at opening pressure, and the pressure volume index. These variables were compared between patients with confirmed cerebrospinal-venous fistula and those with no confirmed source of CSF leak. RESULTS: Thirty-four CT myelograms in 22 patients were analyzed. Eight of 22 (36.4%) patients had confirmed cerebrospinal-venous fistulas. Bolus infusion was well-tolerated with no complications and transient headache in 2/34 (5.8%). Patients with confirmed cerebrospinal-venous fistulas had higher compliance at opening pressure and overall compliance (2.6 versus 1.8 mL/cm H20, P < .01). There was no difference in the pressure volume index (77.5 versus 54.3 mL, P = .13) between groups. CONCLUSIONS: A method of deriving craniospinal space compliance curves using saline intrathecal infusion is described. Preliminary analysis of craniospinal space compliance curves provides qualitative and quantitative information about pressure-volume dynamics and may serve as a diagnostic tool in patients with known or suspected cerebrospinal-venous fistulas.

An audit of local discrepancy rates in acute abdominal CT: does subspecialist reporting reduce discrepancy rates?

AIM: To assess the discrepancy rates (DR) for patients undergoing abdominopelvic computed tomography (CT) for acute non-traumatic abdominal pain who have a subsequent emergency laparotomy in a large university teaching hospital, in particular identifying the differences between subgroups of reporters, to assess factors that may influence the discrepancy rates, to examine the pathologies with the highest discrepancy rate, to identify learning points, and give recommendations on current practice. MATERIALS AND METHODS: The surgical data and CT reports of 1,176 patients who underwent urgent laparotomy after CT from 2014-2018 in a large university hospital were analysed retrospectively. A major discrepancy was defined as an error of fact in the radiology report, which led to incorrect management or patient harm. RESULTS: Registrars have higher DR than consultants (6.86% versus 2.77%). The major DR for consultants met national standards (<5%). The major DRs for registrars met the national audit standard (<10%), but not the National Emergency Laparotomy Audit (NELA) standard (<5%). When comparing between reporter subgroups, gastrointestinal (GI) radiologists have a lower major DR than general radiologists (1.22% versus 3.44%). GI radiologists were also found to correct more registrar provisional reports. The existence of a documented preoperative discussion between radiologists and surgeons was associated with a lower DR. CONCLUSIONS: DR for registrars and consultants are below the national audit standard. Several factors associated with a lower DR in acute abdominopelvic CT were also identified, including reporting by consultants, reporting by GI radiologists and preoperative discussions between the radiologist and surgeon.

Characteristics of adult- compared to childhood-onset type 1 diabetes.

AIMS: To compare diagnosis characteristics, diabetes management and comorbidities in a population diagnosed with type 1 diabetes in childhood with those in a similar population diagnosed in adulthood to identify disease differences related to the age of diabetes onset. METHODS: This analysis was performed using the T1D Exchange Clinic Registry, a cross-sectional survivor cohort. Retrospectively collected characteristics were compared across the following age-at-diagnosis groups: <10, 10-17, 18-24, 25-39 and ≥40 years. RESULTS: The entire cohort included 20 660 participants [51% female, median (interquartile range) age 18 (14-36) years, 82% non-Hispanic white]. Diabetic ketoacidosis at diagnosis was more common among those with onset in childhood. Participants diagnosed as adults were more likely to be overweight/obese at diagnosis and to have used oral agents preceding type 1 diabetes diagnosis (57%). Current insulin pump use was less frequent in participants diagnosed at older ages. Current glycaemic control, measured by HbA1c , insulin requirements and use of a continuous glucose monitor were not different by age at diagnosis. Coeliac disease was the only comorbidity that was observed to have a different frequency by age at diagnosis, being more common in the participants diagnosed at a younger age. CONCLUSIONS: These results show differences and similarities between type 1 diabetes diagnosed in childhood vs adulthood; notably, there was a tendency for there was a higher frequency of diabetic ketoacidosis at onset in children and a higher frequency of use of oral antidiabetes agents in adults. The data indicate that there is little distinction between the clinical characteristics and outcomes of type 1 diabetes diagnosed in childhood vs adulthood. Optimizing glycaemic control remains a challenge in all age groups, with lower use of insulin pumps impacting those diagnosed as adults.
