Glycemic Management in Insulin-Naive Patients in the Inpatient Setting.

Objective: The ideal inpatient insulin regimen efficiently attains the target blood glucose range, effectively treats hyperglycemia, and minimizes the risk of hypoglycemia. The objective of this study was to compare glycemic targets achieved by using correctional monotherapy (CM) and basal-bolus therapy (BBT) in insulin-naive patients in the inpatient setting to determine optimal blood glucose management for these patients. Design: This was a retrospective observational cohort study of 792 patients with diabetes not on home insulin therapy who were admitted to an academic hospital over a 5.5-month period. The percentages of hyperglycemic and hypoglycemic values in each group were compared. Results: Among the 3,112 measured blood glucose values obtained from 792 patients within the first 24 hours of insulin administration, 28.5% were hyperglycemic in the BBT group compared with 23.5% in the CM group. When adjusted for covariates, there was a 23% decrease in hyperglycemia in the BBT group (incidence rate ratio = 0.77, 95% CI 0.64-0.95, P = 0.006). Increases in A1C and admission blood glucose, as well as decreases in admission creatinine and inpatient steroid use, were independently associated with higher rates of hyperglycemia, adjusted for all other covariates. There was no significant difference between the groups in the rate of hypoglycemia in the first 24 hours, which was 1.9% in the BBT group and 1.4% in the CM group (P = 0.301). Conclusion: Utilizing BBT in insulin-naive patients admitted to the hospital within the first 24 hours of insulin administration results in lower rates of hyperglycemia without higher rates of hypoglycemia when compared with CM.

The PrEP resource: a mobile app for clinicians to facilitate screening, prescription and follow up of pre-exposure prophylaxis in the prevention of HIV.

Background Over 2million people worldwide receive a new HIV diagnosis annually. Pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV transmission, but is underprescribed, including in the US. Lack of clinician comfort and knowledge are the most cited reasons for this discrepancy. We aimed to develop a mobile application (app) to address these barriers and improve patient access to PrEP. Methods We established key criteria to develop a point-of-care app that could be utilised in low-resource settings by various clinicians poised to prescribe PrEP therapy. The app underwent two rounds of beta testing and improvement utilising anonymous survey feedback from US physicians in 2023. Results The PrEP Resource tool was developed. Eleven physicians completed the initial survey addressing prescribing practices and app functionality. A total of 27% (3/11) of participants were uncomfortable prescribing PrEP, with the most common reasons being lack of training, unfamiliarity with guidelines and infrequently prescribing the medication. Our follow-up survey, completed by eight physicians, showed that 100% of participants found the app easy to learn and comprehensive enough to initiate PrEP. Conclusion Clinician discomfort due to lack of knowledge and familiarity is the most common reason for not prescribing PrEP. The PrEP Resource is a free tool that guides healthcare professionals through common clinical scenarios regarding PrEP therapy and may improve clinician comfort levels. It can be used in low-resource and low-bandwidth settings typically encountered in lower-middle-income countries where HIV prevalence is the highest. Further study is required to validate its usefulness across different settings.

Caregiver reactions to babbling organize turn-taking interactions: Facilitative effects of vocal versus non-vocal responses.

Turn-taking interactions are foundational to the development of social, communicative, and cognitive skills. In infants, vocal turn-taking experience is predictive of infants' socioemotional and language development. However, different forms of turn-taking interactions may have different effects on infant vocalizing. It is presently unknown how caregiver vocal, non-vocal and multimodal responses to infant vocalizations compare in extending caregiver-infant vocal turn-taking bouts. In bouts that begin with an infant vocalization, responses that maintain versus change the communicative modality may differentially affect the likelihood of further infant vocalizing. No studies have examined how caregiver response modalities that either matched or differed from the infant acoustic (vocal) modality might affect the temporal structure of vocal turn-taking beyond the initial serve-and-return exchanges. We video-recorded free-play sessions of 51 caregivers with their 9-month-old infants. Caregivers responded to babbling most often with vocalizations. In turn, caregiver vocal responses were significantly more likely to elicit subsequent infant babbling. Bouts following an initial caregiver vocal response contained significantly more turns than those following a non-vocal or multimodal response. Thus prelinguistic turn-taking is sensitive to the modality of caregivers' responses. Future research should investigate if such sensitivity is grounded in attentional constraints, which may influence the structure of turn-taking interactions.

Contingency enables the formation of social expectations about an artificial agent.

What environmental regularities support infant communicative learning from social interactions? We propose that infants allocate their attention toward and learn from external events that are contingent on their own behaviors. We tested the robustness of the influence of contingency on communicative learning by using a non-biological stimulus, a remote-controlled car, as the social partner. The car approached infants and produced a speech sound either contingently to infants' vocalizations or on a yoked schedule. Two additional groups had an unfamiliar human experimenter as their social partner in contingent and yoked control conditions. We assessed whether infants formed expectations about their partner's responsiveness to their vocalizations. Expectations made based on contingent responsiveness would support the role of contingency in promoting plasticity in early communicative learning. Infants across all conditions increased their vocalization rates when their partner paused in responding, suggesting that they expected their vocalizations to influence their partners' behavior. Infants vocalized significantly more to the social partner than their caregiver if they received contingent rather than yoked responses from the social partner, regardless of if the partner was a human or non-biological agent. Contingent responses to prelinguistic vocalizations facilitated the formation of expectations for interactivity of social partners.

An exploration into the relationship between insomnia and repetitive negative thinking among cancer survivors.

OBJECTIVE: Insomnia and repetitive negative thinking (RNT) are both prevalent among cancer survivors, yet little work has investigated their interrelationship. To explore the hypothesis that RNT and insomnia are related, we conducted secondary analyses on data from a pilot clinical trial of cognitive behavioral therapy for insomnia (CBT-I) for cancer survivors. METHODS: This study analyzed survey data from 40 cancer survivors with insomnia who participated in a pilot randomized trial of CBT-I. Correlations and linear regression models were used to determine associations between aspects of RNT and related constructs (fear of cancer recurrence [FCR], cancer-specific rumination, worry, and intolerance of uncertainty) and sleep (insomnia and sleep quality), while accounting for psychiatric symptoms such as anxiety and depression. Treatment-related change in RNT was examined using a series of linear mixed models. RESULTS: Evidence for an association between RNT and insomnia among cancer survivors emerged. Higher levels of FCR and cancer-related rumination were correlated with more severe insomnia symptoms and worse sleep quality. Notably, FCR levels predicted insomnia, even after controlling for anxiety and depression. Results identified potential benefits and limitations of CBT-I in addressing RNT that should be examined more thoroughly in future research. CONCLUSIONS: RNT is a potential target to consider in insomnia treatment for cancer survivors.

Timing is (almost) everything: Real options, extreme value theory, climate adaptation, and flood risk management.

Flood risk has become a major concern in many regions due to socio-economic growth and rising water levels. In this paper, we introduce a real options model that integrates the Generalized Additive Models for Location, Scale, and Shape framework with Extreme Value Theory to evaluate adaptation measures for flood risk management. Our model allows for uncertain water level rise, climate indices and growing loss exposure. In a case study of flood risk management for New York City, we find that while immediate investment in a barrier and dike project can provide a substantial net present value ($10.96 billion), investing at the optimal time can significantly improve the investment value by 54.84%. Our sensitivity analysis suggests that discount rate is the most important parameter, followed by the mean level of water rise and the water level rise uncertainty. We also find that investment delay is longer when the discount rate or the water level rise uncertainty is higher or when the expected water level rise is lower.

Sulfurized Two-Dimensional Conductive Metal-Organic Framework as a High-Performance Cathode Material for Rechargeable Mg Batteries.

Rechargeable Mg batteries are a promising energy storage technology to overcome the limitations inherent to Li ion batteries. A critical challenge in advancing Mg batteries is the lack of suitable cathode materials. In this work, we report a cathode design that incorporates S functionality into two-dimensional metal-organic-frameworks (2D-MOFs). This new cathode material enables good Mg2+ storage capacity and outstanding cyclability. It was found that upon the initial Mg2+ insertion and disinsertion, there is an apparent structural transformation that crumbles the layered 2D framework, leading to amorphization. The resulting material serves as the active material to host Mg2+ through reduction and/or oxidation of S and, to a limited extent, O. The reversible nature of S and O redox chemistry was confirmed by spectroscopic characterizations and validated by density functional calculations. Importantly, during the Mg2+ insertion and disinsertion process, the 2D nature of the framework was maintained, which plays a key role in enabling the high reversibility of the MOF cathode.

Comparison of a Novel, Flavor-optimized, Polyethylene Glycol and Sulfate Bowel Preparation With Oral Sulfate Solution in Adults Undergoing Colonoscopy.

INTRODUCTION: A new bowel preparation for colonoscopy has been developed containing poorly absorbed sulfate salts and polyethylene glycol 3350, which retain water within the intestinal lumen resulting in copious diarrhea, thereby cleansing the bowel. The product was formulated to be safe and effective with a sports drink-like flavor. This study evaluated the new flavored polyethylene glycol and sulfate solution (FPSS) compared with a Food and Drug Administration-approved bowel preparation containing sulfate salts only [oral sulfate solution (OSS)]. METHODS: Five hundred adults were enrolled in this multicenter, noninferiority study. Subjects were assigned FPSS or OSS administered in split-dose regimens (PM/AM). FPSS subjects took 2 L of the flavored osmotic solution (1 L at night and 1 L in the morning). OSS was taken according to its approved labeling. Colonoscopies were graded globally and segmentally by blinded local investigators using a 4-point scale (excellent, good, fair, and poor), with "good" and "excellent" considered successful. Safety was assessed by adverse events (AEs) and laboratory testing. RESULTS: A high rate of cleansing success was seen with FPSS (94%), which was noninferior to OSS (94%). This conclusion was confirmed by blinded central readers. Segmental success rates were >90% for both preparations, including the right colon. Questionnaire ratings indicated the FPSS experience was preferred over OSS with 87% of FPSS subjects noting their preparation was "tolerable" to "very easy" to consume versus 74% for OSS. The majority of FPSS subjects agreed their preparation tasted like a sports drink. Gastrointestinal symptoms were the most common AEs. There was no difference between preparations for any AE and no clinically significant differences in laboratory parameters. CONCLUSIONS: The new sports drink-like flavored preparation achieved a high level of cleansing in the study, demonstrating noninferiority to OSS. FPSS was well-tolerated with low rates of expected gastrointestinal symptoms. The optimized flavor of FPSS resulted in significantly better acceptance ratings.

Learning how to learn from social feedback: The origins of early vocal development.

Infants' prelinguistic vocalizations reliably organize vocal turn-taking with social partners, creating opportunities for learning to produce the sound patterns of the ambient language. This social feedback loop supporting early vocal learning is well-documented, but its developmental origins have yet to be addressed. When do infants learn that their non-cry vocalizations influence others? To test developmental changes in infant vocal learning, we assessed the vocalizations of 2- and 5-month-old infants in a still-face interaction with an unfamiliar adult. During the still-face, infants who have learned the social efficacy of vocalizing increase their babbling rate. In addition, to assess the expectations for social responsiveness that infants build from their everyday experience, we recorded caregiver responsiveness to their infants' vocalizations during unstructured play. During the still-face, only 5-month-old infants showed an increase in vocalizing (a vocal extinction burst) indicating that they had learned to expect adult responses to their vocalizations. Caregiver responsiveness predicted the magnitude of the vocal extinction burst for 5-month-olds. Because 5-month-olds show a vocal extinction burst with unfamiliar adults, they must have generalized the social efficacy of their vocalizations beyond their familiar caregiver. Caregiver responsiveness to infant vocalizations during unstructured play was similar for 2- and 5-month-olds. Infants thus learn the social efficacy of their vocalizations between 2 and 5 months of age. During this time, infants build associations between their own non-cry sounds and the reactions of adults, which allows learning of the instrumental value of vocalizing.

CMV-associated collapsing focal segmental glomerulosclerosis after kidney transplant in a pediatric patient.

BACKGROUND: Cytomegalovirus (CMV) is a significant cause of morbidity among immunocompromised patients who have undergone kidney transplantation and is known to rarely induce collapsing focal segmental glomerulosclerosis (FSGS) among adults. METHODS: We present the first reported case of CMV-induced collapsing FSGS in a pediatric patient after kidney transplant. RESULTS: Our patient underwent a deceased donor kidney transplant due to end-stage renal disease secondary to lupus nephritis. Approximately 4 months after transplantation, he developed signs of worsening kidney function in the setting of CMV viremia and was found to have collapsing features of FSGS on kidney transplant biopsy. He was managed with a prompt escalation of antiviral therapy along with a reduction of immunosuppression and recovered without significant complication. At follow-up, he continued to have undetectable CMV titers, creatinine within normal limits, and no significant proteinuria. CONCLUSION: This report demonstrates CMV as a cause of collapsing FSGS and should be considered among pediatric transplant recipients who present with acute kidney injury, as should early assessment of APOL1 genetic status in both donor and recipient.

Identifying and addressing common contributors to nonadherence with ophthalmic medical therapy.

PURPOSE OF REVIEW: To discuss common reasons for nonadherence and review existing and emerging options to reduce nonadherence with ocular medical therapy and optimize therapeutic outcomes. RECENT FINDINGS: Nonadherence can arise from patient-related issues (e.g. physical, cognitive) and healthcare-related issues (e.g. cost, access to care). Multiple strategies have been developed and evaluated to overcome these barriers to adherence. Identifying nonadherence and its cause(s) facilitates the development of strategies to overcome it. SUMMARY: Many common causes of nonadherence can be mitigated through a variety of strategies presented.

Proportion of Malignancy and Evaluation of Sonographic Features of Thyroid Nodules Classified as Highly Suspicious Using ACR TI-RADS Criteria.

OBJECTIVES: The reported malignancy rate of highly suspicious thyroid nodules based on the ACR TI-RADS criteria (TI-RADS category 5 [TR5]) varies widely. The objective of our study was to determine the rate of malignancy of TR5 nodules at our institution. We also aimed to determine the predictive values of individual sonographic features, as well as the correlation of total points assigned to a nodule and rate of malignancy. METHODS: Our single-institution retrospective study evaluated 450 TR5 nodules that had cytology results available, in 399 patients over a 1-year period. Sonographic features and total TI-RADS points were determined by the interpreting radiologist. Statistical analyses included logistic regression models to find factors associated with increased odds of malignancy, and computing sensitivity, specificity, positive and negative predictive values of various individual sonographic features. RESULTS: Of the 450 nodules, 95 (21.1%, 95% exact confidence interval 17.4-25.2%) were malignant. Each additional TI-RADS point increased the odds of malignancy (adjusted odds ratio 1.35, 95% confidence interval 1.13-1.60, P < .001). "Very hypoechoic" was the sonographic feature with the highest specificity and positive predictive value for malignancy (95.5 and 44.8%, respectively), while "punctate echogenic foci" had the lowest positive predictive value (20.0%). CONCLUSIONS: The rate of malignancy of TR5 nodules at our institution was 21.1%, which is lower than other malignancy rates reported in the literature. The total number of points assigned on the basis of the TI-RADS criteria was positively associated with malignancy, which indicates that TR5 should be viewed as a spectrum of risk.

The Survivorship Sleep Program (SSP): A synchronous, virtual cognitive behavioral therapy for insomnia pilot program among cancer survivors.

BACKGROUND: For cancer survivors, insomnia is prevalent, distressing, and persists for years if unmanaged. Cognitive behavioral therapy for insomnia (CBT-I) is an effective treatment yet can be difficult to access and may require modification to address survivorship-specific barriers to sleep. In this 2-phase study, the authors adapted and assessed the feasibility, acceptability, and preliminary effects of synchronous, virtual CBT-I adapted for cancer survivors (the Survivorship Sleep Program [SSP]). METHODS: From April to August 2020, cancer survivors with insomnia (N = 10) were interviewed to refine SSP content and delivery. From October 2020 to March 2021, 40 survivors were recruited for a randomized controlled trial comparing 4 weekly SSP sessions with enhanced usual care (EUC) (CBT-I referral plus a sleep hygiene handout). Feasibility and acceptability were assessed by enrollment, retention, attendance, fidelity, survey ratings, and exit interviews. Insomnia severity (secondary outcome), sleep quality, sleep diaries, and fatigue were assessed at baseline, postintervention, and at 1-month follow-up using linear mixed models. RESULTS: The SSP included targeted content and clinician-led, virtual delivery to enhance patient centeredness and access. Benchmarks were met for enrollment (56% enrolled/eligible), retention (SSP, 90%; EUC, 95%), attendance (100%), and fidelity (95%). Compared with EUC, the SSP resulted in large, clinically significant improvements in insomnia severity (Cohen d = 1.19) that were sustained at 1-month follow-up (Cohen d = 1.27). Improvements were observed for all other sleep metrics except sleep diary total sleep time and fatigue. CONCLUSIONS: Synchronous, virtually delivered CBT-I targeted to cancer survivors is feasible, acceptable, and seems to be efficacious for reducing insomnia severity. Further testing in larger and more diverse samples is warranted.

Distribution and compartmentalization of human circulating and tissue-resident memory T cell subsets.

Knowledge of human T cells derives chiefly from studies of peripheral blood, whereas their distribution and function in tissues remains largely unknown. Here, we present a unique analysis of human T cells in lymphoid and mucosal tissues obtained from individual organ donors, revealing tissue-intrinsic compartmentalization of naive, effector, and memory subsets conserved between diverse individuals. Effector memory CD4(+) T cells producing IL-2 predominated in mucosal tissues and accumulated as central memory subsets in lymphoid tissue, whereas CD8(+) T cells were maintained as naive subsets in lymphoid tissues and IFN-γ-producing effector memory CD8(+) T cells in mucosal sites. The T cell activation marker CD69 was constitutively expressed by memory T cells in all tissues, distinguishing them from circulating subsets, with mucosal memory T cells exhibiting additional distinct phenotypic and functional properties. Our results provide an assessment of human T cell compartmentalization as a new baseline for understanding human adaptive immunity.

Utility of Thyroid Function Testing in the Inpatient Setting.

OBJECTIVE: Previous studies have reported a low value of ordering inpatient thyroid function tests (TFTs), with few changes in clinical management resulting from these tests. This study was designed to evaluate how often testing the thyroid function during hospitalization leads to medication initiation or adjustment and to determine whether the frequency of medication initiation or adjustment differs based on the indication for testing. METHODS: This is a retrospective observational study of 2278 patients who underwent TFTs tested while admitted to an academic hospital during a 5-month period. The indications for ordering TFTs were determined by reviewing clinical documentation, and those with abnormal test results were reviewed to assess whether thyroid medication was initiated or adjusted. RESULTS: The percentage of abnormal TFTs that led to medication initiation or adjustment was 15.1%, 12.2%, and 6.0%, for those tested based on a history of functional thyroid disease, suspicion of thyroid dysfunction, and reasons not directly related to thyroid dysfunction, respectively. Overall, 63 patients were started on thyroid medication or had their thyroid medication dose adjusted, which represented 10.1% of those with abnormal TFTs and only 2.8% of those tested. CONCLUSION: Abnormal TFTs are common, but a disproportionate number of tests are needed to find a small percentage of clinically significant thyroid dysfunction, of which only a low percentage leads to changes in management. Education on this topic should be provided to inpatient providers to limit thyroid function testing to instances in which they are clinically indicated and abnormal results would lead to changes in management.

Outcomes of de novo belatacept-based immunosuppression regimen and avoidance of calcineurin inhibitors in recipients of kidney allografts at higher risk for underutilization.

To describe an experience using a protocol using de novo belatacept (DNB) based maintenance immunosuppression in the setting of lymphocyte depletion. A retrospective, observational study was performed on 37 kidney transplant recipients treated with the DNB protocol, which was defined as belatacept initiated within 7 days after a kidney transplant with steroids and mycophenolate with anti-thymocyte globulin (ATG) induction without concomitant calcineurin inhibitors (CNIs). Patients who received a deceased donor kidney meeting one or more of the following criteria: anticipated cold ischemia time (CIT) greater than 24 h, donation after cardiac death, donor acute kidney injury, and a Kidney Donor Profile Index (KDPI) >85% during the study period were included. Patient survival at 1 year was 97.3% and graft survival was 94.6%. Delayed graft function (DGF) occurred in 40.54% of the patients. Two patients experienced a Banff 1B acute cellular rejection. BK viremia was detected in 32.4% of patients. The mean estimated glomerular filtration rate (eGFR) calculated with the use of modification of diet in renal disease (MDRD) equation at 1 year in the study group was 54.7 ml/min/1.73 m2 . We believe that utilization of the DNB protocol, which allows early CNI avoidance, may decrease organ discard rates.

The scaffold protein WRAP53ß orchestrates the ubiquitin response critical for DNA double-strand break repair.

The WD40 domain-containing protein WRAP53ß (WD40 encoding RNA antisense to p53; also referred to as WDR79/TCAB1) controls trafficking of splicing factors and the telomerase enzyme to Cajal bodies, and its functional loss has been linked to carcinogenesis, premature aging, and neurodegeneration. Here, we identify WRAP53ß as an essential regulator of DNA double-strand break (DSB) repair. WRAP53ß rapidly localizes to DSBs in an ATM-, H2AX-, and MDC1-dependent manner. We show that WRAP53ß targets the E3 ligase RNF8 to DNA lesions by facilitating the interaction between RNF8 and its upstream partner, MDC1, in response to DNA damage. Simultaneous binding of MDC1 and RNF8 to the highly conserved WD40 scaffold domain of WRAP53ß facilitates their interaction and accumulation of RNF8 at DSBs. In this manner, WRAP53ß controls proper ubiquitylation at DNA damage sites and the downstream assembly of 53BP1, BRCA1, and RAD51. Furthermore, we reveal that knockdown of WRAP53ß impairs DSB repair by both homologous recombination (HR) and nonhomologous end-joining (NHEJ), causes accumulation of spontaneous DNA breaks, and delays recovery from radiation-induced cell cycle arrest. Our findings establish WRAP53ß as a novel regulator of DSB repair by providing a scaffold for DNA repair factors.

Dropless cataract surgery: modernizing perioperative medical therapy to improve outcomes and patient satisfaction.

PURPOSE OF REVIEW: Advances in pharmacology offer freedom from topical medical therapy without compromise of anti-inflammatory and antimicrobial coverage in the perioperative period. In this review, we describe the basis for dropless cataract surgery with the goal of improving outcomes and the patient experience. RECENT FINDINGS: Phacoemulsification outcomes depend largely on surgeon skill but also on adherence to a complex multidrug regimen of perioperative anti-inflammatory and antimicrobial therapy to prevent sight-threatening complications such as cystoid macular edema or endophthalmitis. Successful administration of this regimen can be limited by noncompliance, difficulty administering eye drops, bioavailability, and side effects, among others. The recent development of sustained-release formulations of dexamethasone - one an intracanalicular insert and the other an intraocular suspension - can provide sustained tapering doses of dexamethasone while reducing or eliminating the need for anti-inflammatory eye drop therapy. Similarly, mounting evidence compellingly demonstrates that intracameral antibiotic use intraoperatively is at least as effective as topical antibiotics in preventing endophthalmitis. SUMMARY: Sustained-release dexamethasone coupled with intracameral antibiotics at the time of phacoemulsification can provide antimicrobial and anti-inflammatory prophylaxis without the need for topical eye drop medications. This approach has the potential to improve compliance with therapy, visual acuity outcomes, and the overall patient experience.

Correlation of Hemoglobin A1C and Outcomes in Patients Hospitalized With COVID-19.

OBJECTIVE: Diabetes is a known risk factor for severe coronavirus disease 2019 (COVID-19). We conducted this study to determine if there is a correlation between hemoglobin A1C (HbA1C) level and poor outcomes in hospitalized patients with diabetes and COVID-19. METHODS: This is a retrospective, single-center, observational study of patients with diabetes (defined by an HbA1C level of ≥6.5% or known medical history of diabetes) who had a confirmed case of COVID-19 and required hospitalization. All patients were admitted to our institution between March 3, 2020, and May 5, 2020. HbA1C results for each patient were divided into quartiles: 5.1% to 6.7% (32-50 mmol/mol), 6.8% to 7.5% (51-58 mmol/mol), 7.6% to 8.9% (60-74 mmol/mol), and >9% (>75 mmol/mol). The primary outcome was in-hospital mortality. Secondary outcomes included admission to an intensive care unit, invasive mechanical ventilation, acute kidney injury, acute thrombosis, and length of hospital stay. RESULTS: A total of 506 patients were included. The number of deaths within quartiles 1 through 4 were 30 (25%), 37 (27%), 34 (27%), and 24 (19%), respectively. There was no statistical difference in the primary or secondary outcomes among the quartiles, except that acute kidney injury was less frequent in quartile 4. CONCLUSION: There was no significant association between HbA1C level and adverse clinical outcomes in patients with diabetes who are hospitalized with COVID-19. HbA1C levels should not be used for risk stratification in these patients.
