Biological Age Affecting Attrition and Tooth Loss in a Follow-up Study.

In population-based longitudinal studies, bias caused by nonresponse among eligible participants and attrition during follow-up thwarts conclusions. As this issue is not commonly addressed in dental studies, it is the aim of this study to examine the consequences of attrition with respect to tooth loss and mortality in a 10-y follow-up study. From the Study of Health in Pomerania (SHIP-0), a biological age (BA) score was constructed from 10 systemic biomarkers and related to one's actual chronological age (CA).

Periodontitis adversely affects lipoprotein subfractions - results from the cohort study SHIP-TREND: Periodontitis adversely affects lipoprotein subfractions.

Aim: We aimed to investigate the medium-term associations of periodontitis and the number of missing teeth with serum lipoproteins and their plasma subfractions using follow-up data from the population-based Study of Health in Pomerania (SHIP-TREND).

Methods: A total of 2,058 participants with 7-year follow-up data underwent periodontal examinations, serum lipid panel tests, and proton nuclear magnetic resonance (H-NMR) spectroscopy of plasma lipoproteins and their subfractions. Generalized models with gamma distribution and loglink were used to analyze associations between periodontal variables and lipoproteins and their subfractions, adjusting for confounders using propensity score weighting.

SARS-CoV-2 (COVID-19) Experience at an Academic Medical Examiner's Office.

Introduction: The coronavirus disease of 2019 (COVID-19) pandemic has resulted in a great deal of morbidity and mortality worldwide. Since most deaths related to COVID-19 are currently considered natural, and they tend to occur following a clinically recognized illness, many medical examiner/coroner offices within the United States do not take jurisdiction over the majority of COVID-19 deaths.

Methods: In this review, we present the experience of a medium-sized medical examiner's office affiliated with an academic medical school institution, over the first 15 months of the COVID-19 pandemic.

Effect of Discontinuation of Supportive Periodontal Therapy on Periodontal Status-A Retrospective Study.

Aim: To assess the impact of active (APT) and supportive periodontal therapy (SPT) on the change in probing depth (PD) and annual tooth loss in partially and fully compliant and drop-out patients.

Material And Methods: Data of 280 periodontally treated partially and fully compliant (regular supportive visits, SPT duration 5.5 ± 4.
