Prior research links social support with several positive health outcomes. However, less is known about the association between social support and Type 2 diabetes risk factors, such as glycemic control. This study uses a nationally representative sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the relationship between social support and glycated hemoglobin A1c (HbA1c) levels. The data were analyzed through hierarchical logistic regression. Results indicate an inverse relationship between elevated HbA1c levels and individuals’ satisfaction with their partners’ daily interactions. Implications include the possibility of reducing Type 2 diabetes risk through communication interventions highlighting the importance of maintaining positive daily interactions. 相似文献

Background: Prolonged strenuous exercise has a profound effect on cardiac function. The right heart may be more susceptible to this imposition; yet, right-sided chest leads have not been utilised in this setting. Methods: Thirty highly trained athletes at the 2014 Western States 100-mile Endurance Run from Squaw Valley to Auburn, California (body mass 68?±?12?kg, age 45?±?10?years, 57?±?15?miles per week) were recruited for the study. Pre- and post-race, a right-sided 12-lead ECG was obtained and data were extracted for P, R and S waves, J point, ST segment and T wave amplitude. Data were compared using Students T-test and statistical significance set as P?.05. Results: There was a significant increase in P wave amplitude (29%) and QTc interval (4%) pre- to post-race from standard 12-lead ECG. From the right-sided12-lead ECG, a 23% (P?=?.01) and 38% (P?=?.03) increase in J point amplitude in V1R and V2R and a 22% (P?=?.05) increase in ST segment integral in V2R and V3R were evident. T wave inversion was evident in leads V2R–V6R in 50–90% of athletes, respectively. Close examination revealed marked heterogeneity in individual ECGs. Conclusions: Completion of a 100-mile ultra-marathon resulted in significant changes in the right-sided ECG alongside more marked responses in specific individuals. P wave, ST segment and T wave changes post-race are indicative of acute exercise-induced right heart electrical adaptation. 相似文献

Air pollution is one of the environmental influences that degrade cultural heritage objects situated indoors. Other essential influences, such as temperature, relative humidity, and light are often well monitored. The presence of air pollutants is less often measured or included in risk assessment. The MEMORI® technology presented in this paper was developed as a tool for easy measurement and assessment of the general risk of degradation of heritage objects situated indoors due to indoor exposure to air pollutants. MEMORI dosimetry was performed in locations belonging to English Heritage and Tate (both located in London) and the National Archives of Norway in Oslo, to assess air quality. The related damage risk for collection objects and the protection offered by display and storage designs was assessed. A high level of acidic effect was observed inside a number of showcases, and a high level of oxidizing effect was observed in some room locations. Relatively simple mitigation measures, such as constructing tightly sealed showcases using low emitting materials, installing active carbon absorbing media inside a ‘microclimate’ frame, and using cardboard storage boxes for paper, significantly improved air quality. Overall, implementation of such measures is likely to improve the preservation of objects and reduce conservation costs. 相似文献

This study replicates and extends research on college students’ sexual possible selves by longitudinally examining their sexual expectations, fears, and behavioral strategies at the beginning and end of the first semester in college. Open-ended responses were collected at two time points (T1, N?=?78; T2, N?=?40) and were analyzed using directed content analysis. First semester students’ salient expectations and fears focused on abstinence, interpersonal relationships, quantity, conditional sex, decreasing/avoidant behaviors, and fears related to sexual health/well-being, sexual assault/coercion, self-focus, and increased sexual risk at both T1 and T2. However, two new themes emerged at T2: maintain (expected) and partner-focus (feared). At both time points, behavioral strategies included abstinence, making opportunities, restricting boundaries, sexual health/well-being, thoughtful/informed decisions, and self-assertion/protection. Quantitative frequency comparisons were also conducted to examine changes in the prevalence of the reported categories and indicated shifts in salient expectations, fears, and strategies across the first semester. Implications for sexual education are discussed. 相似文献

Attachment and Biobehavioral Catch‐up (ABC) is a parenting program developed to enhance sensitivity among parents of infants who experience early adversity. In several randomized clinical trials, the intervention's efficacy has been demonstrated. Moving interventions into the community with adequate fidelity is challenging, though, and intervention effects are often much smaller than when tested in randomized clinical trials. To enhance the likelihood that ABC is delivered with high fidelity, a microanalytic fidelity assessment was developed. Using this fidelity tool as a central component of training, supervision, and certification, changes in parent sensitivity for 108 families with children ages 6 months to 2 years were as large as those seen in laboratory settings. These findings are discussed with regard to implications for moving other evidence‐based interventions into the community. 相似文献

The search by naturalists for good characters upon which to base both classifications and determinations of species led some 19th century entomologists to put their faith in insect genitalia as a criteria by which they could differentiate between and classify forms. Karl Jordan was such an entomologist, who turned to these tiny structures as an aid to his work as a museum curator to identify, describe and classify moths and butterflies. In his writings on the subject he also demonstrated how the attempts of systematists to order the diversity of nature had profound implications for the efforts of biologists to explain the origin of that diversity. However, Jordan's plan of how to do systematics well required much more than convincing biologists of the importance of museum work. It also depended on refining the priorities of a natural history community that worked according to diverse means, priorities and methods during a tumultuous century. 相似文献

This article reports the findings from a mixed-methods study on factors that influence women’s decisions about birth, with the view that women’s decision making about birth can affect the use of cesarean surgery. Data was collected from focus groups and structured postpartum interviews and was analyzed using the Consensual Qualitative Research method. The findings relate specifically to the factors reported as influential in making decisions about birth including how the women categorized, prioritized, and/or favored certain types of knowledge about modes of birth. Four major information categories were identified but only stories about birth and/or attending a birth appeared to have a lasting effect on birth choices. These findings have implications for prenatal and perinatal education and nursing practice. 相似文献
