Preventive Behaviors as Correlates of Periodontal Health Status

Objectives: This investigation examined current practices of brushing, flossing, and periodic dental visits and their association with periodontal health status. Methods : Data were collected using face-to-face interviews and 40-minute in-home dental examinations with a probability sample of adults 18 years of age or older, having at least one tooth, and living in housing units in the Detroit tricounty area. Complete examinations were performed on 319 individuals. Results : On average, subjects reported brushing their teeth about twice a day. About one-third of the population reported flossing at least once a day. Loss of periodontal attachment was related to frequency of brushing while subjects who exhibited acceptable flossing ability had less plaque and calculus, shallower pocket depths, and less attachment loss. Subjects reporting a periodic dental visit at least once a year had less plaque, gingivitis, and calculus than subjects reporting less frequent visits. In regression analyses, brushing thoroughness, flossing ability and frequency, and dental visit frequency were predictors of lower plaque, gingivitis, and calculus scores. In turn, these scores were predictors of shallower pocket depths and less attachment loss. Conclusions : Brushing, flossing, and periodic dental visits were correlated with better periodontal health. The behaviors appeared to be indirectly related to pocket depth and attachment loss through their associations with plaque, gingivitis, and calculus levels.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/65572/1/j.1752-7325.1995.tb02324.x.pd

Galactorrhea associated with juvenile systemic lupus erythematosus: a review of the role of prolactin

This case report is based on the clinical observation of a patient with juvenile systemic lupus erythematosus (SLE) who developed transient galactorrhea. The subsequent literature review documented an interesting association between prolactin and rheumatic diseases and in particular, hyperprolactinemia and SLE. The discussion that follows the case report explores this relationship and proposes a hypothesis regarding why this patient with juvenile SLE developed galactorrhea

Shear-induced quench of long-range correlations in a liquid mixture

A static correlation function of concentration fluctuations in a (dilute) binary liquid mixture subjected to both a concentration gradient and uniform shear flow is investigated within the framework of fluctuating hydrodynamics. It is shown that a well-known $|\nabla c|^2/k^4$ long-range correlation at large wave numbers $k$ crosses over to a weaker divergent one for wave numbers satisfying $k<(\dot{\gamma}/D)^{1/2}$, while an asymptotic shear-controlled power-law dependence is confirmed at much smaller wave numbers given by $k\ll (\dot{\gamma}/\nu)^{1/2}$, where $c$, $\dot{\gamma}$, $D$ and $\nu$ are the mass concentration, the rate of the shear, the mass diffusivity and the kinematic viscosity of the mixture, respectively. The result will provide for the first time the possibility to observe the shear-induced suppression of a long-range correlation experimentally by using, for example, a low-angle light scattering technique.Comment: 8pages, 2figure

Predictors of Adherence to Nutrition Recommendations in People With Non- Insulin-Dependent Diabetes Mellitus

The purpose of this study was to determine how the components of psychosocial adjustment to diabetes predict adherence to nutrition recommendations based on self-reported successful completion of contingency contracts. The relationships between the components of psychosocial adjustment and adherence to nutrition recommendations were examined in a convenience sample of patients with non-insulin- dependent diabetes mellitus participating in a contingency contracting intervention with nurses. Patients completed a standardized instrument, the Diabetes Care Profile, at the time they were enrolled into this randomized clinical trial. High and low levels of adherence to nutrition recommendations were identified by a median split of the number of contingency contracts completed for adherence to nutrition recommendations. Subjects who reported higher regimen adherence and a higher support ratio (received more diabetes-specific social support than desired) were significantly less likely to engage in contingency contracting for adherence to nutrition recommendations .Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/68967/2/10.1177_014572179702300206.pd

Physical Activity Effects on Depressive Symptoms in Black Adults

Objectives: Randomized trials found physical activity (PA) effective in decreasing depressive symptoms. Few studies included Black participants. The purpose of this systematic literature review was to determine the effects of PA on depressive symptoms in Black adults. Methods: Articles were abstracted by conducting a computer and hand search of eligible studies. Results: Eight of 13 studies found a significant inverse relationship between PA and depressive symptoms in Black adults. Sources for the heterogeneity were explored. Conclusion: Future studies should include representative samples of Black adults, incorporate a theory which considers multiple levels of influence, account for genetic factors in the etiology of depressive symptoms, include individuals diagnosed with depression and with health conditions which may increase the risk of depressive symptoms, account for intra-group ethnic heterogeneity, measure and differentiate between social support and social network, consider aspects of the physical environment and use standardized measurements of PA

Depressive Symptoms and Walking in African‐Americans

Objective Although increased frequency of physical activity is associated with fewer depressive symptoms in African‐Americans, most studies do not focus on a specific type of activity. Identifying the activity can provide helpful information for designing interventions that focus on depressive symptoms. The objective of this study was to examine the odds of depressive symptoms in relation to walking in African‐Americans. Design and Sample A secondary analysis was performed on the National Survey of American Life. The sample was made up of community‐dwelling African‐American women (n = 1,903) and men (n = 1,075) who did not meet the DSM‐IV‐TR criteria for depression. Measures Walking was measured by self‐reported frequency (i.e., never, rarely, sometimes, often). Depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale. Logistic regression for complex samples was used to examine the odds of depressive symptoms in relation to walking. Results Women who reported often walking had lower odds for depressive symptoms than women who reported never walking (OR = 0.56, 95% CI = 0.38–0.82). Walking frequency was not related to depressive symptoms in men. Conclusions Walking frequency is a modifiable risk factor for elevated depressive symptoms in African‐American women

Effect of Dietary Fats on Oxidative-Antioxidative Status of Blood in Rats

This study was performed to examine the effect of different fat sources, lard, sunflower oil (SO), and fish oil (FO) in high-fat and low-fat diet on reactive oxygen species generation by blood phagocytes, glutathione redox status in erythrocytes, and total plasma antioxidant ability in rats. Whole blood chemiluminescence (CL) did not differ between three low-fat fed groups. However, baseline and phorbol myristate acetate (PMA)-stimulated CL in blood of high-lard fed rats were lower than in low-lard and high-SO fed animals. Phagocyte-stimulated oxidative burst was higher in rats fed high-SO diet than in those fed low-SO and high-FO diets. The highest level of oxidize glutathione (GSSH), the lowest reduce glutathione (GSH)/GSSG ratio in erythrocytes, and the highest plasma activity to reduce ferric ions were observed in rats fed both diets contaning linoleic acid-rich sunflower oil compared to animals fed the corresponding energy from other fats. 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of plasma was lower in high-lard and high-FO fed rats compared to the corresponding low-fat diets, and the lowest in low-FO fed rats among low-fat fed animals. We presume from our results that linoleic acid may have dual effect, prooxidative in blood cells but maintaining total antioxidant plasma ability

Gardening/Yard Work and Depressive Symptoms in African Americans

Background The purpose of this study was to examine the frequency of gardening/yard work in relation to depressive symptoms in African-Americans while controlling for biological and social factors. Methods A secondary analysis was performed on the National Survey of American Life (n = 2,903) using logistic regression for complex samples. Gardening/Yard work was measured by self-reported frequency. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale. Results Biological and social factors, not gardening/yard work, were associated with depressive symptoms. Conclusions Biological and social factors may need to be addressed before the association between gardening/yard work and depressive symptoms can be determined

Leisure-time Physical Activity in Relation to Depressive Symptoms in African-Americans: Results from the National Survey of American Life

Objective To examine the frequency of leisure-time physical activity (LTPA) in relation to depressive symptoms in a nationally representative sample of African American (AA) women and AA men with guidance by Stokols\u27 Social Ecological Framework. Method A secondary analysis of AA women (n = 1811) and AA men (n = 1038) was performed on the National Survey of American Life, where a four stage national area probability sampling was conducted. Interviews were conducted 2001–2003. Clinically depressed AA were excluded from the current study. LTPA was measured by self-report frequency (never, rarely, sometimes, often) of participation in sports/exercise. Depressive symptoms were measured with the Center for Epidemiologic Studies Depression scale. Logistic regression for complex samples was used to examine the relationship between LTPA and depressive symptoms, adjusting for biopsychobehavioral and sociophysical environmental factors. Results Compared with AA women and AA men who reported never participating in LTPA, the multivariate OR for depressive symptoms in AA women and AA men who reported participating in LTPA often was 0.42 (95% CI = 0.24–0.72) and 0.41 (95% CI = 0.25–0.69) respectively. Conclusion Increased frequency of LTPA was associated with fewer depressive symptoms in a nationally representative sample of non-clinically depressed AAs
