COVID-19 vaccination was a rare potential etiology for cause of death after medicolegal autopsy. A Finnish nationwide study. (preprint)

COVID-19 vaccinations began globally at the end of 2020. By the end of 2021, 9.8 million doses were given in Finland. Regarding safety, most vaccine-related adverse reactions have been mild, but serious and lethal ones have also occurred. Autopsies in post vaccination deaths may give insight to the extent of fatal health conditions with potential COVID-19 vaccine etiology and provide new hypotheses of possible causalities between vaccination and severe health conditions. We searched the complete documentation on all medicolegal autopsies in Finland between December 2020 and December 2021 to assess how often the basis for autopsy was a suspected fatal adverse reaction to COVID-19 vaccination, and whether vaccination remained a potential etiology for any health condition determined as a cause of death after the autopsy. We linked register-based data on individual COVID-19 vaccination course and pre-existing health conditions. We found 428 autopsy cases with a mention of COVID-19 vaccination, and prior to autopsy, vaccination was suspected to play a part in 76 deaths. Post autopsy, a forensic pathologist considered vaccination as a potential etiology in five underlying and seven contributory causes of death. These included seven thromboembolisms, two diabetic ketoacidoses, one myocarditis, one acute pancreatitis, and one eosinophilic granulomatosis with polyangiitis. In relation to the number of vaccinations within Finland, a suspicion of vaccine-related serious adverse reaction was rarely an indication for medicolegal autopsy. Even less frequently was vaccination considered to play a part in the process leading to death, although considerable doubt remains in the accuracy of individual considerations, and autopsy cannot definitively confirm causality between vaccination and death. Regarding vaccination safety, continuing evaluation of suspected vaccine-related deaths is essential, and an autopsy should be part of the investigation when such a suspicion arises.

Diabetes related emergency department visits among adults during the COVID-19 pandemic - an analysis of data from the New York City syndromic surveillance system (preprint)

ObjectiveNew York City was an early epicenter of the COVID-19 pandemic. We aim to describe population level epidemiological trends in diabetes related emergency department (ED) visits among adults in New York City, for the period prior to and encompassing the first four waves of the pandemic. Research Design and MethodsWe used data from the New York City ED syndromic surveillance system during December 30, 2018 through May 21, 2022. This system captures all visits from EDs in the city in near-real time. We matched these visits to laboratory confirmed COVID-19 positivity data beginning with February 15, 2020. ResultsCompared to pre-pandemic baseline levels, diabetes related ED visits noticeably increased during the first wave in spring 2020, though this did not necessarily translate to net increases overall during that period. Visits for diabetic ketoacidosis, particularly among adults with type 2 diabetes, sharply increased before returning to pre-pandemic levels, most notably during wave 1 and wave 4 in winter 2021-2022. Trajectories of diabetes-related ED visits differed by diabetes type, age, and sex. Some ED visit trends did not return to pre-pandemic baseline levels. ConclusionsThe COVID-19 pandemic, especially the first wave in the spring of 2020, coincided with a dramatic shift in diabetes related ED utilization in New York City. Our findings highlight the importance of on-going surveillance of health care utilization for chronic diseases during population-level emergencies like pandemics. A robust syndromic surveillance system that includes infectious and non-infectious syndromes is useful to better prepare, mitigate, and respond to population-level events.

Clinical Presentation and Outcomes of Care in Adults with Diabetic Ketoacidosis Pre-COVID-19 and during-COVID-19 at a Tertiary, Referral Hospital in Nairobi, Kenya (preprint)

Background Diabetic Ketoacidosis (DKA) is a potentially life-threatening diabetic emergency requiring prompt recognition and care. The prognosis of DKA has improved over time with the availability of evidence-based protocols and resources. However, in Kenya, there are limited resources for the appropriate diagnosis and management of DKA, and these are limited to tertiary-level referral facilities. This study aimed to review the clinical presentation, management, and outcomes of adult patients admitted with DKA at the Aga Khan University Hospital, Nairobi, over five years and assess differences in these parameters before and during the COVID-19 pandemic.Methods This was a retrospective study of DKA admissions from January 2017 to December 2021. Patient data were retrieved from the medical records department using ICD-10 codes, and individual details were abstracted on clinical presentation, management, and outcomes of DKA. Comparisons were made between pre-COVID-19 and during COVID-19 durations.Results 150 patients admitted with DKA were included (n = 48 pre- COVID-19, n = 102 during COVID-19 (n = 23 COVID-19 positive, n = 79 COVID-19 negative)). Median age was 47 years (IQR 33.0, 59.0), median HbA1C was 12.4% [IQR 10.8, 14.6]), and most patients had severe DKA (46%). Most common DKA precipitants were infections (40.7%), newly diagnosed diabetes (33.3%) and missed medication (25.3%). There was a significant difference in pulmonary infections as a DKA precipitant, between the pre- COVID and during COVID-19 pandemic (21.6% during COVID-19 versus 6.3% pre- COVID-19; p = 0.012). Median total insulin dose used was 110.0 units [IQR 76.0, 173.0], and a 100% of patients received basal insulin. The median length of hospital stay was 4.0 days [IQR 3.0, 6.0] and time to DKA resolution was 30.0 hours [IQR 24.0, 48.0]. There were 2 deaths (1.3%), none directly attributable to DKA. Severity of DKA significantly differed between pre- COVID-19, COVID-19 positive and COVID-19 negative DKA (52.2% of COVID-19 positive had moderate DKA compared to 26.6% of COVID-19 negative and 22.9% of Pre-COVID-19 (p = 0.006)).Conclusion These findings indicate that even in developing regions, good outcomes can be achieved with the appropriate facilities for DKA management. Clinician and patient education is necessary to ensure early detection and prompt referral to avoid patients presenting with severe DKA. Exploratory studies are needed to assess reasons for prolonged time to DKA resolution found in this study.

Ketoacidosis as a primary manifestation of COVID-19.

INTRODUCTION: Diabetic ketoacidosis is the most important metabolic emergency in children. Children mimic many syndromes with a combination of nonspecific symptoms during the COVID-19 pandemic. Many syndromes are triggered by changes in children's body conditions. Reporting specific cases can improve the diagnosis process. The present study reports an 18-month-old paediatric case of COVID-19 who presented ketoacidosis (DKA) symptoms. CASE PRESENTATION: The case is an 18-month-old child with fever and diarrhoea from 3 days before, who did not respond to outpatient treatment. On the day of the visit, he suffered from deep and abdominal breathing and decreased level of consciousness and sugar levels at admission of 420 mg/dl. He was then admitted with the initial diagnosis of DKA and had a positive PCR test result for COVID-19. CONCLUSIONS: Considering the non-specific symptoms of COVID-19, general practitioners and paediatricians are recommended that special attention be paid to these symptoms, especially those that are similar to life-threatening syndromes. They also should not easily ignore these symptoms and follow up patients and their recovery status and, if patients do not recover, consider the risk of COVID-19 given the current COVID-19 pandemic.

New-onset type 1 diabetes in children and adolescents as postacute sequelae of SARS-CoV-2 infection: A systematic review and meta-analysis of cohort studies.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in children and adolescents may increase risk for a variety of post-acute sequelae including new-onset type 1 diabetes mellitus (T1DM). Therefore, this meta-analysis aims to estimate the risk of developing new-onset type 1 diabetes in children and adolescents as post-acute sequelae of SARS-CoV-2 infection. PubMed/MEDLINE, CENTRAL, and EMBASE were systematically searched up to March 20, 2023. A systematic review and subsequent meta-analyses were performed to calculate the pooled effect size, expressed as risk ratio (RR) with corresponding 95% confidence interval (CI) of each outcome based on a one-stage approach and the random-effects estimate of the pooled effect sizes of each outcome were generated with the use of the DerSimonian-Laird method. Eight reports from seven studies involving 11 220 530 participants (2 140 897 patients with a history of diagnosed SARS-CoV-2 infection and 9 079 633 participants in the respective control groups) were included. The included studies reported data from four U.S. medical claims databases covering more than 503 million patients (IQVIA, HealthVerity, TriNetX, and Cerner Real-World Data), and three national health registries for all children and adolescents in Norway, Scotland, and Denmark. It was shown that the risk of new-onset T1DM following SARS-CoV-2 infection in children and adolescents was 42% (95% CI 13%-77%, p = 0.002) higher compared with non-COVID-19 control groups. The risk of developing new-onset T1DM following SARS-CoV-2 infection was significantly higher (67%, 95% CI 32 %-112%, p = 0.0001) in children and adolescents between 0 and 11 years, but not in those between 12 and 17 years (RR = 1.10, 95% CI 0.54-2.23, p = 0.79). We also found that the higher risk for developing new-onset T1DM following SARS-CoV-2 infection only exists in studies from the United States (RR = 1.70, 95% CI 1.37-2.11, p = 0.00001) but not Europe (RR = 1.02, 95% CI 0.67-1.55, p = 0.93). Furthermore, we found that SARS-CoV-2 infection was associated with an elevation in the risk of diabetic ketoacidosis (DKA) in children and adolescents compared with non-COVID-19 control groups (RR = 2.56, 95% CI 1.07-6.11, p = 0.03). Our findings mainly obtained from US medical claims databases, suggest that SARS-CoV-2 infection is associated with higher risk of developing new-onset T1DM and diabetic ketoacidosis in children and adolescents. These findings highlight the need for targeted measures to raise public health practitioners and physician awareness to provide intervention strategies to reduce the risk of developing T1DM in children and adolescents who have had COVID-19.

Acute pancreatitis associated with diabetic ketoacidosis in a child with COVID-19 infection.

BACKGROUND: There is a mutual influence between COVID-19, diabetes ketoacidosis, and acute pancreatitis, with clinical manifestations overlapping each other, which can lead to misdiagnosis and delayed treatment that could aggravate the condition and affect the prognosis. COVID-19-induced diabetes ketoacidosis and acute pancreatitis are extremely rare, with only four case reports in adults and no cases yet reported in children. CASE PRESENTATION: We reported a case of acute pancreatitis associated with diabetic ketoacidosis in a 12-year-old female child post novel coronavirus infection. The patient presented with vomiting, abdominal pain, shortness of breath, and confusion. Laboratory findings showed elevated levels of inflammatory markers, hypertriglyceridemia, and high blood glucose. The patient was treated with fluid resuscitation, insulin, anti-infection treatments, somatostatin, omeprazole, low-molecular-weight heparin, and nutritional support. Blood purification was administered to remove inflammatory mediators. The patient's symptoms improved, and blood glucose levels stabilized after 20 days of admission. CONCLUSION: The case highlights the need for greater awareness and understanding of the interrelated and mutually promoting conditions of COVID-19, diabetes ketoacidosis, and acute pancreatitis among clinicians, to reduce misdiagnosis and missed diagnoses.

SARS-CoV-2 Positive Serology and Islet Autoantibodies in Newly Diagnosed Pediatric Cases of Type 1 Diabetes Mellitus: A Single-Center Cohort Study.

Acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, although presenting less severe forms of the disease in children, seems to play a role in the development of other conditions, including type 1 diabetes mellitus (T1DM). After the beginning of the pandemic, an increase in the number of T1DM pediatric patients was observed in several countries, thus leading to many questions about the complex relationship between SARS-CoV-2 infection and T1DM. Our study aimed to highlight possible correlations between SARS-CoV-2 serology and T1DM onset. Therefore, we performed an observational retrospective cohort study that included 158 children diagnosed with T1DM in the period April 2021-April 2022. The presence or absence of SARS-CoV-2 and T1DM-specific antibodies and other laboratory findings were assessed. In the group of patients with positive SARS-CoV-2 serology, a higher percentage had detectable IA-2A antibodies, more children were positive for all three islet autoantibodies determined (GADA, ICA, and IA-2A), and a higher mean HbA1c value was found. No difference existed between the two groups regarding DKA presence and severity. A lower C-peptide level was found in the patients presenting diabetic ketoacidosis (DKA) at T1DM onset. When compared to a group of patients diagnosed before the pandemic, an increased incidence of both DKA and severe DKA, as well as a higher age at diagnosis and higher levels of HbA1c were present in our study group. These findings have important implications for the ongoing monitoring and management of children with T1DM after the COVID-19 pandemic and highlight the need for further research to better understand the complex relationship between SARS-CoV-2 infection and T1DM.

Safety of sodium-glucose cotransporter 2 inhibitors (SGLT2i) during the month of Ramadan in patients with type 2 diabetes mellitus in Pakistani population-an observational study from a tertiary care center in Karachi.

BACKGROUND AND AIMS: Primary aim was to assess the safety of SGLT2-i in patients with Type 2 Diabetes Mellitus (T2D) in a real-life scenario during Ramadan by finding the frequency and severity of hypoglycemic/hyperglycemic events, dehydration, and Diabetic ketoacidosis (DKA). Secondary aim was to assess changes in glycated hemoglobin (HbA1c), weight and creatinine levels. METHODS: This prospective, observational, controlled cohort study was conducted at Aga Khan University Hospital, Karachi, Pakistan from March 15 to June 30, 2021. Participants were over 21 years of age, on stable doses of SGLT2-I, which was started at least 2 months before Ramadan. Endpoint assessments were done 1 month before and within 6 weeks after Ramadan. RESULTS: Of 102 participants enrolled, 82 completed the study. Most (52%) were males, with mean age 52.2 ± 9.5 years and average duration of T2D 11.2 ± 6.5 years. 63% were on Empagliflozin (mean dose; 14.8 ± 7.2 mg/day) whereas 37% were on Dapagliflozin (mean dose; 8.2 ± 2.7 mg/day). Six (7.3%) documented symptoms of hypoglycemia. However, no episode of severe hypoglycemia, hyperglycemia, dehydration, DKA, hospitalization or discontinuation of SGLT2i was reported. HbA1c changes were (7.7 ± 1.2% from 7.9 ± 2.3%, p 0.34), weight (78.4 ± 12.9 kgs from 78.9 ± 13.3, p 0.23) and eGFR (87.8 ± 27.9 from 94.3 ± 37.6, p < 0.001). The reasons of study participants drop outs were: six did not keep any fasts; four discontinued study participation for personal reasons; three were out of city and missed post Ramadan follow-up, two protocol violation and five could not be contacted for post-Ramadan follow up during the third wave of COVID-19. CONCLUSION: Results showed the safety of SGLT2i agents during Ramadan in the Pakistani population recommending it as a treatment option in adults with T2D, without any additional adverse events.

COVID-19 associated ketosis and diabetic ketoacidosis: A rapid review.

SARS-CoV-2 infection could disrupt the endocrine system directly or indirectly, which could result in endocrine dysfunction and glycaemic dysregulation, triggering transient or persistent diabetes mellitus. The literature on the complex relationship between COVID-19 and endocrine dysfunctions is still evolving and remains incompletely understood. Thus, we conducted a review on all literature to date involving COVID-19 associated ketosis or diabetic ketoacidosis (DKA). In total, 27 publications were included and analysed quantitatively and qualitatively. Studies included patients with DKA with existing or new onset diabetes. While the number of case and cohort studies was limited, DKA in the setting of COVID-19 seemed to increase risk of death, particularly in patients with new onset diabetes. Future studies with more specific variables and larger sample sizes are needed to draw better conclusions.

A UK nationwide study of adults admitted to hospital with diabetic ketoacidosis or hyperosmolar hyperglycaemic state and COVID-19.

AIMS: To investigate characteristics of people hospitalized with coronavirus-disease-2019 (COVID-19) and diabetic ketoacidosis (DKA) or hyperosmolar hyperglycaemic state (HHS), and to identify risk factors for mortality and intensive care admission. MATERIALS AND METHODS: Retrospective cohort study with anonymized data from the Association of British Clinical Diabetologists nationwide audit of hospital admissions with COVID-19 and diabetes, from start of pandemic to November 2021. The primary outcome was inpatient mortality. DKA and HHS were adjudicated against national criteria. Age-adjusted odds ratios were calculated using logistic regression. RESULTS: In total, 85 confirmed DKA cases, and 20 HHS, occurred among 4073 people (211 type 1 diabetes, 3748 type 2 diabetes, 114 unknown type) hospitalized with COVID-19. Mean (SD) age was 60 (18.2) years in DKA and 74 (11.8) years in HHS (p < .001). A higher proportion of patients with HHS than with DKA were of non-White ethnicity (71.4% vs 39.0% p = .038). Mortality in DKA was 36.8% (n = 57) and 3.8% (n = 26) in type 2 and type 1 diabetes respectively. Among people with type 2 diabetes and DKA, mortality was lower in insulin users compared with non-users [21.4% vs. 52.2%; age-adjusted odds ratio 0.13 (95% CI 0.03-0.60)]. Crude mortality was lower in DKA than HHS (25.9% vs. 65.0%, p = .001) and in statin users versus non-users (36.4% vs. 100%; p = .035) but these were not statistically significant after age adjustment. CONCLUSIONS: Hospitalization with COVID-19 and adjudicated DKA is four times more common than HHS but both associate with substantial mortality. There is a strong association of previous insulin therapy with survival in type 2 diabetes-associated DKA.

Characterization of Newly Diagnosed Type 1 Diabetes in Children and Adolescents from 2017–2022 in China: A Single-center Analysis (preprint)

OBJECTIVE This study investigated the characteristics of newly diagnosed type 1 diabetes mellitus (T1DM) related to autoimmunity and the frequency of diabetic ketoacidosis (DKA) in children and adolescents from 2017–2022 in China.RESEARCH DESIGN AND METHODS Single-center regional data from the Department of Pediatric Endocrinology, Tongji Hospital, were used to compare 88 children and adolescents newly diagnosed with T1DM from 2020 to 2022 (i.e. during the COVID-19 pandemic in China) and 76 children and adolescents diagnosed with T1DM from 2017 to 2019. Auto-antibodies, including glutamic acid decarboxylase-65 and insulin auto-antibodies, were detected by enzyme-linked immunoassays. DKA was defined as a pH < 7.3 and/or a bicarbonate level < 15 mmol/L.RESULTS The median age of the 164 children and adolescents newly diagnosed with T1DM from 2017 to 2022 was 7.0 years (interquartile range [IQR]: 3.8–10.0 years; 51.83% male). The mean annual incidence of T1DM was 4.25/100,000. The estimated frequency of auto-antibody positivity was 51.22% (n = 84), and there was no difference between the 2020–2022 group and 2017–2019 group (55.68% [n = 49] vs. 46.5% [n = 35]; p = 0.219). The incidence of DKA among the entire cohort was 57.93% (n = 95). The frequency of DKA was not significantly higher in the 2020–2022 group compared with the 2017–2019 group (60.23% [n = 53] vs. 55.26% [n = 42]; p = 0.521). We found no significant difference in the frequency of DKA between patients who were negative vs. positive for auto-antibodies in the 2020–2022 group (64.10% [n = 25] vs. 57.14% [n = 28], p > 0.05). The C-peptide level and HbA1c (%) were positively correlated with onset age (R1 = 0.389, p < 0.01; R2 = 0.371, p < 0.01), and the estimated mean C-peptide level was 0.26 ng/ml (IQR: 0.2–0.4 ng/ml) in patients with DKA and 0.370 ng/ml (IQR: 0.2–0.6 ng/ml) in patients without DKA (p = 0.044).CONCLUSIONS This study showed the annual incidence of T1DM was 4.25/100,000, gradually increased over the study period, and there was no significant increase in T1DM with auto-antibody positivity in children and adolescents newly diagnosed from 2020–2022 in China compared with the previous 3 years. Furthermore, the frequencies of DKA were not significantly different between patients who were negative vs. positive for auto-antibodies.

Incidence and presentation of new-onset type 1 diabetes in children and adolescents from Germany during the COVID-19 pandemic 2020 and 2021: Current data from the DPV Registry.

AIMS: To determine whether the incidence of type 1 diabetes mellitus (T1D), autoantibody-negative diabetes, and diabetic ketoacidosis (DKA) at diabetes onset in 2020 and 2021 changed when compared to long-standing trends. METHODS: Our study is based on diabetes manifestation data of the 0.5-<18-year-old children/adolescents from the German multicenter Diabetes Prospective Follow-up Registry. Based on long-term pre-pandemic trends from 2011 to 2019, we estimated adjusted incidence rate ratios (IRR) for T1D and DKA, and prevalence rate ratios (PRR) regarding autoantibody status with 95 % confidence intervals (CI) for the years 2020 and 2021 (observed versus predicted rates), using multivariable negative binomial or beta-binomial regression, respectively. RESULTS: We analyzed data of 30,840 children and adolescents with new-onset T1D. The observed incidences were significantly higher than the predicted incidences (IRR2020 1.13 [1.08-1.19]; IRR2021 1.20 [1.15-1.26]). The prevalence of autoantibody-negative diabetes did not change (PRR2020 0.91 [0.75-1.10]; PRR2021 1.03 [0.86-1.24]). The incidence of DKA during the pandemic was higher than predicted (IRR2020 1.34 [1.23-1.46]; IRR2021 1.37 [1.26-1.49]). CONCLUSIONS: An increase in the incidences of T1D and DKA, but not of autoantibody-negative diabetes was observed during both pandemic years. Further monitoring and efforts for DKA prevention at onset are necessary.

Characteristics and burden of diabetic ketoacidosis in diabetic patients in the period of COVID-19 outbreak in Ethiopia (preprint)

Background: Diabetic ketoacidosis (DKA) is an acute life-threatening complication of diabetes mellitus. This study aimed to evaluate the clinical characteristics and the burden of DKA cases during the period of the COVID-19 outbreak in Ethiopia. Methods: An institutional-based retrospective chart review study was conducted. 178 randomly selected patients’ medical charts were included. Data were collected from medical records in the period between October 2020 to July 2022. To investigate the association between the dependent and independent variable, binary and multivariable logistic regression were done with statistically significant at P ≤0.05. Results: A total of 178 medical records were reviewed. The mean (±SD) age of the patients was 41.3 (±13.2) years and 45% of patients had type 2 diabetes. Acute diabetic complications were documented in 25.8% of patients where DKA was the commonest (16.3%). Nearly half of the DKA patients (n=13, 44.8%) were presented with poly-symptoms at the time of diagnosis. Furthermore, missing drug (31%) was the most frequent precipitating factor followed by community-acquired pneumonia (21%), and multiple factors (17%). Besides, patients in the DKA group had a higher mean length of hospital stay (3 days versus 2.6 days). Conclusion: The poly-symptoms were the common clinical features of DKA at the time of presentation. Pneumonia and a history of missing drugs were identified as leading precipitating factors of DKA. Even though the DKA complication is low in this research, diabetes health education at the community and institutional level, routine screening for diabetes at health centers, and treating the infections early are strongly recommended.

Incidence of new-onset type 1 diabetes during Covid-19 pandemic: A French nationwide population-based study.

AIM: The association between infection with SARS-CoV-2 and the development of new-onset type 1 diabetes mellitus (T1DM) is unclear. The aim of this study was to examine the impact of the Covid-19 pandemic on the hospitalization rates for new-onset T1DM and diabetic ketoacidosis at diagnosis, in metropolitan France. METHODS: This nationwide retrospective cohort study included hospital data on all patients aged 1 to 35 years old, hospitalized in France due to onset of T1DM, in 2020 and 2021 compared to 2019. RESULTS: Apart from a decrease during the lockdown in 2020, the number of hospitalizations due to new-onset T1DM was not significantly different in 2020 and 2021 than it was in 2019. In the regions most affected by Covid-19 and covering 7,995,449 inhabitants aged from 1 to 35 years old, standardized hospitalization rates were not significantly different in 2020 and in 2021 compared with 2019. The number of hospitalizations for diabetic ketoacidosis at diagnosis was not significantly different after week 14 in 2020 and in 2021 compared with 2019. CONCLUSION: In this nationwide study, the incidence of hospitalizations for new-onset T1DM and the incidence of diabetic ketoacidosis at diagnosis was not increased during the Covid-19 pandemic in 2020 and 2021. Our results support the fact that infection with SARS-CoV-2 does not promote the development of T1DM.

Incidence, Severity, and Presentation of Type 2 Diabetes in Youth During the First and Second Year of the COVID-19 Pandemic.

OBJECTIVE: To describe the evolving impact of the coronavirus disease 2019 pandemic on the incidence and presentation of new-onset pediatric type 2 diabetes. RESEARCH DESIGN AND METHODS: Retrospective medical record review of youth with new-onset type 2 diabetes comparing the prepandemic period (1 January 2017-29 February 2020) with the first (1 March 2020-31 December 2020) and second pandemic year (1 January 2021-31 December 2021). RESULTS: The annualized incidence of type 2 diabetes increased nearly threefold during the pandemic versus prior, with a 61% increase in the 2nd versus 1st year. BMI increased during the pandemic versus prior (129% of 95th percentile vs. 141%, P = 0.02). In the 1st year, patients were younger (12.9 years vs. 14.8, P < 0.001), with higher incidence of diabetic ketoacidosis and/or hyperglycemic hyperosmolar syndrome (20% vs. 3.5%, P = 0.02) versus prior. CONCLUSIONS: Providers should be aware of the escalating incidence of youth-onset type 2 diabetes to avoid delays in diagnosis and inform educational programs to combat the continued impact of the pandemic on health outcomes.
