Type 2 diabetes and depression in the African American population

Potential transition of depression of older adults affected by socioeconomic status show different styles: A longitudinal study of Chinese older adults

Socioeconomic status' (SES) impact on depressive symptoms has been extensively examined; however, previous studies have generally used variable-centered approaches and cross-sectional designs. Therefore, this study explored the subtypes of depression and examined the degree of association between SES and latent transition probabilities. We used latent profile and latent transition analyses with the 2015 and 2018 waves of data from the China Health and Retirement Longitudinal Study (N = 4904). Three subtypes of depression were identified based on symptoms: severe symptom (SS), low symptom (LS), and sub-health (MS). The SS subtype had the highest probability of staying within the original subtype. Individuals in the MS subtype were more likely to move to the SS subtype than those in the LS subtype. The heterogeneity analysis also showed that the effect of SES on latent transition probabilities is heterogeneous to the satisfaction with their relationship with their children, as well as the number of children. Additionally, decision tree analysis found SES and gender can predict transitioning. These findings add to literature on the effects of SES on the heterogeneity of depression and have implications for depression screening and identifying individuals in need of targeted interventions.

Factors Associated With Diabetes Self-Care Performance in Indonesians With Type 2 Diabetes: A Cross-Sectional Study

BACKGROUND

In Indonesia, the number of Type 2 diabetes cases is increasing rapidly, making it the third leading cause of death and among the leading noncommunicable disease healthcare expenditures in the country. Thus, there is a critical need for Indonesians with Type 2 diabetes to perform better self-care to optimize their health and prevent the onset of comorbidities.

PURPOSE

This study was designed to investigate the influence of knowledge, depression, and perceived barriers on Type 2 diabetes self-care performance in Indonesia.

METHODS

A cross-sectional study was conducted on 185 patients with Type 2 diabetes, with demographic, diabetes history, obesity status, diabetes knowledge, depression, perceived barriers, and self-care performance data collected. The Indonesian version of the Revised Diabetes Knowledge Test, Depression Anxiety Stress Scale, Perceived Barrier Questionnaire and Self-Care Inventory-Revised were used. Descriptive, bivariate, and multiple linear regression analyses were performed.

RESULTS

Study participants were found to have moderate diabetes self-care performance scores. Annual eye checks, blood glucose self-monitoring, healthy diet selection, and regular exercise were the least common self-management techniques performed and were consistent with the perceived difficulties of the participants. Being illiterate or having an elementary school education (β = 4.59, p = .002), having a junior or senior high school education (β = 3.01, p = .006), having moderate depression (β = -0.92, p = .04), diabetes knowledge (β = 0.09, p = .006), and perceived barriers (β = 0.31, p < .001) were found to explain 40% of the variance in self-care performance. Educational level, depression, and perceived barriers were the strongest factors that impacted Type 2 diabetes self-care performance in this study.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

Nurses should not only provide diabetes education but also identify barriers to diabetes self-care early, screen for the signs and symptoms of depression, and target patients with lower levels of education.

Impact of Diabetes Self-Management Education on A1C Levels Among Black/African Americans: A Systematic Review

PURPOSE

The purpose of this systematic review was to examine the impact of diabetes self-management education (DSME) programs on A1C levels of Black/African American adults with type 2 diabetes.

METHODS

Authors followed PRISMA guidelines and searched PubMed and CINAHL databases to identify articles published from 2000 to date. The primary outcome was A1C and participation in a DSME program among Black/African Americans with diabetes.

RESULTS

Nine high-quality randomized control trials (RCTs) were included in this review. Sample sizes ranged between 48 and 211. Studies reported Black/African American samples ranging from 23% to 57% (n = 4), 4 reported 100%, and 1 reported 96%. Most (56%) reported a statistically significant decline in A1C levels postprogram, whereas 44% noted insignificant changes. All the studies compared the DSME intervention effect to a control group or another type of diabetes self-management program.

CONCLUSION

The results suggest that DSME programs can be effective at lowering A1C levels in Black/African American adults; however, more research with larger sample sizes of Black/African Americans is warranted. The availability of meta-analyses and more RCTs could also further strengthen the external validity of this review. Additionally, future studies focused on A1C outcomes within DSME programs not combined with other self-management interventions among Black/African Americans can advance science regarding the impact of DSME programs among this disparate population.

Takotsubo Syndrome in Black Americans: Insights From the National Inpatient Sample

BACKGROUND

Data on race-related differences in the clinical outcomes of Takotsubo syndrome are limited, particularly for Black patients. This study aimed to assess whether race and sex may have an additional impact on the inpatient mortality of patients with Takotsubo syndrome.

METHODS

A total of 4,628 patients from the United States' National Inpatient Sample from 2012 to 2016 were identified; propensity score analysis revealed a similar propensity score between Black patients (n = 2,314) and White patients (n = 2,314), which was used to balance observed covariates. Sex and age distributions were identical between the 2 groups. The groups were also similar in baseline characteristics, including cardiovascular risk factors. White patients were compared with Black patients on in-hospital outcomes and inpatient mortality. A logistic regression analysis was conducted to measure the difference in mortality based on race and sex.

RESULTS

Compared with White patients, Black patients had a higher percentage of in-hospital complications, including cerebrovascular accidents (4.9% vs 2.5%, P ≤ .01), acute kidney injury (25% vs 19%, P ≤ .01); longer lengths of stay (8 vs 7 days, P ≤ .01); and higher inpatient mortality (6.1% vs 4.5%, P < .01). When analysis was conducted with race and sex combined, inpatient mortality was higher among Black men than among White women (odds ratio, 2.7 [95% CI, 1.80-3.95]; P ≤ .01).

CONCLUSION

This study showed that Black patients with Takotsubo syndrome have higher in-hospital complications and inpatient mortality rates. When race and sex were combined, inpatient mortality was significantly higher among Black men than among either White men and women or Black women.

Stromal heterogeneity may explain increased incidence of metaplastic breast cancer in women of African descent

The biologic basis of genetic ancestry-dependent variability in disease incidence and outcome is just beginning to be explored. We recently reported enrichment of a population of ZEB1-expressing cells located adjacent to ductal epithelial cells in normal breasts of women of African ancestry compared to those of European ancestry. In this study, we demonstrate that these cells have properties of fibroadipogenic/mesenchymal stromal cells that express PROCR and PDGFRα and transdifferentiate into adipogenic and osteogenic lineages. PROCR + /ZEB1 + /PDGFRα+ (PZP) cells are enriched in normal breast tissues of women of African compared to European ancestry. PZP: epithelial cell communication results in luminal epithelial cells acquiring basal cell characteristics and IL-6-dependent increase in STAT3 phosphorylation. Furthermore, level of phospho-STAT3 is higher in normal and cancerous breast tissues of women of African ancestry. PZP cells transformed with HRasG12V ± SV40-T/t antigens generate metaplastic carcinoma suggesting that these cells are one of the cells-of-origin of metaplastic breast cancers.

Diabetic foot ulcer self-care assessment: a scoping review

OBJECTIVES

to map, in the world literature, instruments for assessing foot self-care of people with diabetes.

METHODS

a scoping review in Scopus by Elsevier, MEDLINE via PubMed, LILACS, SciELO databases and gray literature, using the controlled words diabetic foot, self care, questionnaire. Search was carried out in February and March 2021, according to JBI recommendations and PRISMA-ScR extension.

RESULTS

fifteen studies made up the review, 14 articles and one thesis, published between 2000 and 2020. 16 instruments were identified: five with an emphasis on general self-care and 11 on foot self-care. Inspection, hygiene, washing and drying between the toes, lotion application and use of proper shoes and socks were the main self-care measures presented.

FINAL CONSIDERATIONS

foot self-care is assessed by knowledge, social support and frequency with which measures are being put into practice, encouraging professional practice.

Health literacy, illness perception, depression, and self-management among African Americans with type 2 diabetes

BACKGROUND

Type 2 diabetes mellitus (T2DM) causes significant morbidity and mortality. Compared with non-Hispanic Whites, African Americans are more likely to suffer and die from T2DM.

PURPOSE

This study examines the associations between health literacy, illness perception, depression, working memory, executive function, and self-management among African Americans (18-65 years) with T2DM.

METHODOLOGY

A descriptive cross-sectional design was used. Data were collected through Research Electronic Data Capture and transferred to the Statistical Package for the Social Sciences software version 26 for statistical analysis. Fifty-three participants met study eligibility criteria.

RESULTS

Health literacy was associated with depression ( r = -0.433, p = .003), more concerns about illness ( r = -0.357, p = .02), and better medication adherence ( r = 0.487, p = .001). Higher levels of depression were inversely associated with medication adherence ( r = -0.449, p = .002; r = 0.449, p = .003). Higher concern about illness was associated with lower medication adherence ( r = -0.414, p = .005).

CONCLUSIONS

Lower health literacy coupled with illness perception and depression is associated with lower self-management behaviors among African Americans which can lead to complications of T2DM. More studies are needed to examine the association of cognitive factors with self-management activities among African Americans with T2DM.

IMPLICATIONS

Limited health literacy is associated with lower medication adherence among African Americans with T2DM. Illness perception is a significant factor that influences self-management of T2DM among African Americans. Using screening tools that assess health literacy and illness perception may address underlying concerns regarding adherence to T2DM treatment regimens in African Americans.

To the Future: The Role of Exosome-Derived microRNAs as Markers, Mediators, and Therapies for Endothelial Dysfunction in Type 2 Diabetes Mellitus

The prevalence of diabetes mellitus (DM) is increasing at a staggering rate around the world. In the United States, more than 30.3 million Americans have DM. Type 2 diabetes mellitus (T2DM) accounts for 91.2% of diabetic cases and disproportionately affects African Americans and Hispanics. T2DM is a major risk factor for cardiovascular disease (CVD) and is the leading cause of morbidity and mortality among diabetic patients. While significant advances in T2DM treatment have been made, intensive glucose control has failed to reduce the development of macro and microvascular related deaths in this group. This highlights the need to further elucidate the underlying molecular mechanisms contributing to CVD in the setting of T2DM. Endothelial dysfunction (ED) plays an important role in the development of diabetes-induced vascular complications, including CVD and diabetic nephropathy (DN). Thus, the endothelium provides a lucrative means to investigate the molecular events involved in the development of vascular complications associated with T2DM. microRNAs (miRNA) participate in numerous cellular responses, including mediating messages in vascular homeostasis. Exosomes are small extracellular vesicles (40-160 nanometers) that are abundant in circulation and can deliver various molecules, including miRNAs, from donor to recipient cells to facilitate cell-to-cell communication. Endothelial cells are in constant contact with exosomes (and exosomal content) that can induce a functional response. This review discusses the modulatory role of exosomal miRNAs and proteins in diabetes-induced endothelial dysfunction, highlighting the significance of miRNAs as markers, mediators, and potential therapeutic interventions to ameliorate ED in this patient group.

Depression Treatment Status of Economically Disadvantaged African American Older Adults

Background: It is known that depression remains largely untreated in underserved communities. Hence, it is desirable to gain more knowledge on the prevalence and correlates of untreated depression among African-American (AA) older adults in economically disadvantaged areas. This knowledge may have the public health benefit of improving detection of AA older adults with depression who are at high risk of not receiving treatment, thereby reducing this health disparity. Objective: To study health and social correlates of untreated depression among AA older adults in economically disadvantaged areas. Methods: Between 2015 and 2018, this cross-sectional survey was conducted in South Los Angeles. Overall, 740 AA older adults who were 55+ years old entered this study. Independent variables were age, gender, living arrangement, insurance type, educational attainment, financial strain, chronic medical conditions, and pain intensity. Untreated depression was the dependent variable. Logistic and polynomial regression models were used to analyze these data. Results: According to the polynomial regression model, factors such as number of chronic medical conditions and pain intensity were higher in individuals with depression, regardless of treatment status. As our binary logistic regression showed, age, education, and number of providers were predictive of receiving treatment for depression. Conclusion: Age, educational attainment, number of providers (as a proxy of access to and use of care) may be useful to detect AA older adults with depression who are at high risk of not receiving treatment. Future research may focus on decomposition of the role of individual-level characteristics and health system-level characteristics that operate as barriers and facilitators to AA older adults receiving treatment for depression.
