Making sense of glucose metrics in diabetes: linkage between postprandial glucose (PPG), time in range (TIR) & hemoglobin A1c (A1C).
While A1C is the standard diagnostic test for evaluating long-term glucose management, additional glucose data, either from fingerstick blood glucose testing, or more recently, continuous glucose monitoring (CGM), is necessary for safe and effective management of diabetes, especially for individuals treated with insulin. CGM technology and retrospective pattern-based management using various CGM reports have the potential to improve glycemic management beyond what is possible with fingerstick blood glucose monitoring. CGM software can provide valuable retrospective data on Time-in-Ranges (above, below, within) metrics, the Ambulatory Glucose Profile (AGP), overlay reports, and daily views for persons with diabetes and their healthcare providers. ⋯ Time-in-Ranges data provide an easy-to-define metric that can facilitate goal setting discussions between clinicians and persons with diabetes to improve glycemic management and can empower persons with diabetes in self-management between clinic consultation visits. Here we discuss multiple real-life scenarios from a primary care clinic for the application of CGM in persons with diabetes. Optimizing the use of the reports generated by CGM software, with attention to time in range, time below range, and postprandial glucose-induced time above range, can improve the safety and efficacy of ongoing glucose management.

The impact of delayed heart rate recovery on prevalent hypertension.
Objectives: Delayed heart rate recovery (HRR) is considered an indicator of autonomic nervous dysfunction, which is a primary pathological mechanism of hypertension. The present study aimed to explore the independent association between delayed HRR and prevalent hypertension. Methods: In this cross-sectional study, 314 inpatients were recruited between January 2018 and December 2019. ⋯ Conclusion: Delayed HRR was independently associated with prevalent hypertension. The association was linear and robust over the entire range of HRR. The present study suggested that delayed HRR could be used to optimize hypertension risk stratification.

Hearing impairment prevalence and risk factors among adults in rural China: a population-based cross-sectional study.
Objective: Over the past few decades, the prevalence of hearing impairment (HI) has rapidly increased, making HI one of the most common causes of disability, globally. The burden of HI is particularly heavy in low socioeconomic status populations. Despite extensive research into the range of HI prevalence in low socioeconomic status populations, worldwide, population-based studies have been rare. ⋯ Compared with the 45-54-year-old group, the risk of HI in individuals in the 55-64-year-old, 65-74-year-old, and ≥75-year-old groups were 25.8%, 109.9%, and 373.7% higher, respectively. Moreover, increased with each 1-mmHg SBP, the risk of HI increase 0.7% (95%CI: 1.001-1.013; P = 0.017); while increased with each 1-mmHg DBP, the risk of HI decrease 1.7% (95%CI: 0.973-0.993; P = 0.001)Conclusions: The burden of HI in rural northern China is heavy, especially among elderly men and people with elevated systolic blood pressure (SBP). Addressing HI prevention is critical for reducing the HI burden and improving quality of life.

Usefulness of Atherogenic index of plasma for estimating Reduced eGFR risk: Insights from the National Health and Nutrition Examination Survey 2009-2016.
Previous studies have identified Atherogenic index of plasma (AIP) as a simple measure of atherosclerosis. Because atherosclerosis plays a role in the development of renal damage, our study aims to evaluate the effect of AIP on the risk of reduced eGFR and assess its usefulness to refine the risk stratification of reduced estimated glomerular filtration rate (eGFR). ⋯ The present work suggested a linear association between AIP and reduced eGFR. Furthermore, the results showed that the association was stronger in black race and people aged less than 50 years old. Most importantly, our work implicated the usefulness of AIP to refine the risk stratification of reduced eGFR.

Similar clinical outcome of AMA immunoblot-M2-negative compared to immunoblot-positive subjects over six years of follow-up.
Background: The detection of anti-mitochondrial antibodies (AMA) is considered a hallmark in diagnosing primary biliary cholangitis (PBC). The most important AMA-subtype is AMA-M2 directed against the E2-subunit of pyruvate dehydrogenase. It is common clinical interpretation that lack of M2 due to immunoblotting (IB) indicates absence of specific auto-reactivity. ⋯ According to the clinical course by the time of FU, subjects were allocated to one of four groups: a) 34 patients had known PBC with n = 16 having an adequate and 18 an inadequate treatment response, b) 1 de novo PBC was detected, c) 13 were AMA-positive without biochemical evidence of PBC and d) 9 subjects were tested AMA-negative at FU. These numbers were comparable to M2-positive subjects with similar long-term clinical outcome. Conclusion: Our data suggest that the clinical value of confirmatory M2 immunoblotting in the diagnostic routine of PBC is overestimated as the clinical course appears not to be related to the test result.
