Smoking negatively affects the prognosis of periodontal disease by impairing tissue healing. While micronucleus is the most popular parameter for demonstrating DNA damage, inflammatory cell and vascular densities are the most evaluated parameters for determining histopathologic changes in the periodontium. This study aimed to study the effects of periodontitis and cigarette smoking on genotoxic changes in exfoliated oral epithelial cells and histopathologic changes in periodontal tissue. ⋯ The most intense inflammatory cell and vascular densities occurred in SGP and NGP groups, respectively; and the mildest values were in healthy periodontium groups. Histopathological damage score decreased significantly by group in order SGP > NGP > SHP > NHP. The synergy arising from the combination of smoking and periodontitis exposures exacerbates genotoxic and histopathologic damage in oral cells and the periodontium.

This study aimed to develop a risk prediction nomogram for endometrial carcinoma and precancerous lesions in postmenopausal women to provide postmenopausal patients with more information on disease probability, work out personalized medical plans, and reduce unnecessary invasive clinical examinations. We enrolled 340 patients who underwent hysteroscopy at Beijing Maternity Hospital between March 2016 and July 2018. The patients were divided into the low-risk (275 patients) and high-risk (65 patients) groups, according to the results of the pathological examinations. ⋯ A high C-index value of 0.844 could still be reached in the interval validation. Obesity, vaginal bleeding, family history of gynecological malignancies, endometrial thickness ≥ 1.15 cm, and color Doppler flow imaging blood flow were independent risk factors for endometrial cancer and precancerous lesions. Thus, the prediction nomogram can be conveniently used to facilitate individual risk prediction in patients with endometrial cancer and precancerous lesions.

Periodontal disease is often neglected and overlooking its initial symptoms can lead to tooth loss and systemic diseases. Patients with otitis media are at high risk of vestibular and balance dysfunction, consequently, and vertigo. Vertigo and dizziness are conditions with high reported incidences; they worsen with age and can burden health systems. ⋯ Compared with the controls, the risk of dizziness among patients with periodontal disease was higher for both female (HR: 1.439, 95%: 1.203, 1.720) and male patients (HR: 1.284, 95%: 1.123, 1.468); this risk was higher even when January (HR: 1.302, 95% CI: 1.145, 1.480), February (HR: 1.337, 95% CI: 1.178, 1.518), or March was excluded (HR: 1.308, 95% CI: 1.151, 1.487) and for patients without Ménière disease. Therefore, periodontal disease is not only a risk factor for dizziness but also an independent risk factor for dizziness. Future studies could clarify the mechanisms linking periodontal disease to dizziness.

Randomized Controlled Trial Multicenter Study
A phase 2/3 study of S-217622 in participants with SARS-CoV-2 infection (Phase 3 part).
Limited treatment options exist for patients with mild-to-moderate coronavirus disease 2019 (COVID-19), irrespective of vaccination history or risk status. Ensitrelvir is a novel oral severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) 3C-like (3CL) protease inhibitor. While phase 2 studies of ensitrelvir have demonstrated promising results in treating mild-to-moderate COVID-19, evaluation of its clinical efficacy due to shifting vaccination status and emergence of the Omicron variant represents significant challenges. Here, we describe the protocol for a phase 3 study designed to evaluate the efficacy and safety of ensitrelvir in patients with mild-to-moderate COVID-19, regardless of risk status or vaccination history. ⋯ In a post hoc analysis of the phase 2b study, compared with placebo, ensitrelvir demonstrated a reduced time to resolution of 5 symptoms in patients with mild-to-moderate COVID-19. Through this study, we intend to validate and establish the efficacy and safety of ensitrelvir in patients with mild-to-moderate COVID-19.

Since the outbreak of coronavirus disease 2019, many people have had to reduce their outdoor activities. Therefore, a convenient, simple, at-home training method to improve or maintain cardiopulmonary function is required. This study aimed to explore the therapeutic effect of weight-bearing Liuzijue Qigong on cardiopulmonary function in healthy volunteers. ⋯ Weight-bearing Liuzijue Qigong training significantly improved cardiopulmonary function in healthy volunteers, thus representing home-based cardiopulmonary rehabilitation training.
