Background Recently, flipped classrooms (FCs) have gradually been used in Chinese higher education settings. However, few studies have focused on the effects of FCs on interdisciplinary curricula. The purpose of this study was to examine the impact of an FC on the engagement, performance, and perceptions of students and on teacher-student interaction in a pharmaceutical marketing course. Design A clustered randomized controlled study was conducted, with 137 junior-year pharmacy undergraduates using an FC serving as the intervention group, in contrast to students using lecture-based learning (LBL) as the control group. Flanders’ interaction analysis system (FIAS) was used to measure teacher-student interaction, and questionnaires regarding attitudes toward and satisfaction with the teaching model were administered. Results The students in the FC group scored significantly higher than those in the LBL group (88.21±5.95 vs. 80.05±5.59, t = -8.08, p = 0.000) on pharmaceutical marketing. The multiple linear regression results showed that the FC model had a significant impact on student performance (β = 8.16, p <0.0001). The percentages of teacher talk in the FC and LBL groups were 21% and 96%, respectively (χ 2 = 2170.274, p = 0.000); however, the percentages of student talk in the FC and LBL groups were 75% and 2.6%, respectively (χ 2 = 2012.483, p = 0.000). Compared with the LBL group, most students in the FC group held more positive attitudes toward the teaching model; the mean scores for the 8 attitude attributes in the FC group were significantly higher than those in the LBL group ( p = 0.000). There were significant differences in the ratings of satisfaction with teacher-student interaction ( p = 0.000), the students’ learning attitude ( p = 0.000), the teacher’s preparatory work ( p = 0.000), the teaching objective ( p = 0.000), and the teaching effect ( p = 0.000) between the two groups. Conclusion Compared with LBL methods, implementing the FC model improved student performance, increased teacher-student interaction and generated positive student attitudes toward the experience. As an effective pedagogical model, it can also stimulate pharmacy students’ learning interest and improve their self-learning abilities.

Objective: Exploring how the theory of planned behavior (TPB), social capital theory (SCT), cervical cancer knowledge (CCK), and demographic variables predict behavioral intentions (BI) related to cervical cancer screening among Chinese women. Methods: Self-administered questionnaires were distributed to 496 women, followed by a path analysis. Results: The three-level model was acceptable, χ2(26, 470) = 26.93, p > 0.05. Subjectively overcoming difficulties, support from significant others, screening necessity, and the objective promotion factor promoted BI, with effect sizes of 0.424, 0.354, 0.199, and 0.124. SCT and CCK promoted BI through TPB, with effect sizes of 0.262 and 0.208. Monthly income, education, age, and childbearing condition affected BI through TPB, SCT, and CCK, with effect sizes of 0.269, 0.105, 0.065, and −0.029. Conclusion: The three-level model systematically predicted behavioral intentions relating to cervical cancer screening.

BackgroundAtrial fibrillation (AF) is an age-related disease, while telomeres play a central role in aging. But the relationship between AF and telomere length (LTL) is still controversial. This study aims to examine the potential causal association between AF and LTL by using Mendelian randomization (MR).MethodsBidirectional two-sample MR, expression and protein quantitative trait loci (eQTL and pQTL)-based MR were performed using genetic variants from United Kingdom Biobank, FinnGen, and a meta-analysis study, which comprised nearly 1 million participants in the Atrial Fibrillation Study and 470,000 participants in the Telomere Length Study. Apart from the inverse variance weighted (IVW) approach as the main MR analysis, complementary analysis approaches and sensitivity analysis were applied.ResultsThe forward MR revealed a significant causal estimate for the genetically predicted AF with LTL shortening [IVW: odds ratio (OR) = 0.989, p = 0.007; eQTL-IVW: OR = 0.988, p = 0.005; pQTL-IVW: OR = 0.975, p &lt; 0.005]. But in the reverse MR analysis, genetically predicted LTL has no significant correlation with AF (IVW: OR = 0.995, p = 0.916; eQTL-IVW: OR = 0.999, p = 0.995; pQTL-IVW: OR = 1.055, p = 0.570). The FinnGen replication data yielded similar findings. Sensitivity analysis ensured the stability of the results.ConclusionThe presence of AF leads to LTL shortening rather than the other way around. Aggressive intervention for AF may delay the telomere attrition.

Background: Anticoagulation clinic (AC) is aimed at improving anticoagulation control and outcomes in patients with atrial fibrillation (AF). There is little published data on the benefits of providing an AC in China even if Asians have a higher risk of hemorrhage and stroke when taking warfarin. This study attempts to assess the impact of the AC on warfarin management in the Chinese population. Subjects and Methods: This prospective observational study was conducted in the First Affiliated Hospital of Nanjing Medical University and consecutively enrolled 42 AF patients from the joint physician-and pharmacist-managed AC from March 2017 to April 2018. The study protocol was approved by the Institutional Review Board of the First Affiliated Hospital of Nanjing Medical University. Patients already on warfarin for at least 6 months before coming to the AC and unwilling to receive AF ablation or switch to non-Vitamin K antagonist oral anticoagulants were included. The anticoagulant activity of warfarin was monitored using the international normalized ratio (INR). The primary outcome of this study was INR control, which was defined by the time-in-therapeutic range (TTR). The TTR before and after visiting the AC was compared. Results: The mean age of the enrolled 42 patients was 68.3 ± 10.6 years and 25 (59.5%) were women. The mean CHA2DS2-VASc score and the mean HAS-BLED score were 3.43 ± 1.29 and 1.86 ± 0.80, respectively, in 28 (66.7%) patients with nonvalvular AF. The median follow-up time after visiting the AC was 298.5 days (interquartile range: 151.8–441.8 days). The TTR (% days) before and after visiting the AC was 44.1% ± 27.5% and 69.7% ± 23.3% (P < 0.001), respectively. Meanwhile, 6 (14.3%) and 25 (59.5%) patients had TTR (% days) >65% before and after visiting the AC (P = 0.001), respectively. Conclusions: TTR values were higher in AF patients taking warfarin after the AC. More patients reached satisfactory warfarin control after visiting the AC.
