Spatial correspondence of cortical activity measured with whole head fNIRS and fMRI: Toward clinical use within subject.

Functional near infrared spectroscopy (fNIRS) and functional magnetic resonance imaging (fMRI) both measure the hemodynamic response, and so both imaging modalities are expected to have a strong correspondence in regions of cortex adjacent to the scalp. To assess whether fNIRS can be used clinically in a manner similar to fMRI, 22 healthy adult participants underwent same-day fMRI and whole-head fNIRS testing while they performed separate motor (finger tapping) and visual (flashing checkerboard) tasks. Analyses were conducted within and across subjects for each imaging approach, and regions of significant task-related activity were compared on the cortical surface. The spatial correspondence between fNIRS and fMRI detection of task-related activity was good in terms of true positive rate, with fNIRS overlap of up to 68 % of the fMRI for analyses across subjects (group analysis) and an average overlap of up to 47.25 % for individual analyses within subject. At the group level, the positive predictive value of fNIRS was 51 % relative to fMRI. The positive predictive value for within subject analyses was lower (41.5 %), reflecting the presence of significant fNIRS activity in regions without significant fMRI activity. This could reflect task-correlated sources of physiologic noise and/or differences in the sensitivity of fNIRS and fMRI measures to changes in separate (vs. combined) measures of oxy and de-oxyhemoglobin. The results suggest whole-head fNIRS as a noninvasive imaging modality with promising clinical utility for the functional assessment of brain activity in superficial regions of cortex physically adjacent to the skull.

Household food insecurity is associated with greater autonomic dysfunction testing score in Latinos with type 2 diabetes.

AIM: We examined household food insecurity (HFI) and autonomic nervous system (ANS) function in a subset of low-income Latinos with type 2 diabetes with data from a stress management trial. METHODS: InclusionLatino or Hispanic, Spanish speaking, age less than 18 years, ambulatory status, type 2 diabetes more than 6 months, A1c less than 7.0%. ExclusionPain or dysfunction in hands (e.g., arthritis) precluding handgrip testing; medical or psychiatric instability. HFI was assessed with the 6-item U.S. household food security survey module; with responses to > = 1 question considered HFI. An ANS dysfunction index was calculated from xix autonomic function tests which were scored 0 = normal or 1 = abnormal based on normative cutoffs and then summed. Autonomic function tests were: 1) 24-hour heart rate variability as reflected in standard deviation of the normal-to-normal (SDNN) heart rate acquired with 3-channel, 7-lead ambulatory electrocardiogram (Holter) monitors; 2) difference between the highest diastolic blood pressure (DBP) during sustained handgrip and the average DBP at rest; 3) difference between baseline supine and the minimal BP after standing up; and, from 24-hour urine specimens 4) cortisol, 5) normetanephrine, and, 6) metanephrine. RESULTS: Thirty-five individuals participated, 23 (65.7%) of them were women, age mean = 61.6 (standard deviation = 11.2) years, HbA1c mean = 8.5% (standard deviation = 1.6) and 20 participants (57.1%) used insulin. Twenty-two participants (62.9%) reported HFI and 25 (71.4%) had one or more abnormal ANS measure. Independent t-tests showed that participants with HFI had a higher ANS dysfunction index (mean = 1.5, standard deviation = 0.9) than patients who were food secure (mean = 0.7, standard deviation = 0.8), p = 0.02. Controlling for financial strain did not change significance. Total ANS index was not related to glycemia, insulin use or other socioeconomic indicators. In this sample, HFI was associated with ANS dysfunction. Policies to improve food access and affordability may benefit health outcomes for Latinos with diabetes.

Depression and Anxiety Mediate the Relationship between Discrimination and Well-Being in a Sample of Latinx Adults with Type 2 Diabetes: Results from a Dual Mediation Analysis.

Latinxs experience greater risk for type 2 diabetes, discrimination, and poor mental health. The pathways linking these factors, however, are not well understood. This study tested whether depression and anxiety mediated the relationship between discrimination and well-being. Bootstrapped mediation tests were conducted using a sample of Latinx adults with type 2 diabetes (n = 121) and regression models adjusted for demographic and health covariates. Depression and anxiety fully and jointly mediated the effect of discrimination on well-being; everyday discrimination was linked to elevated symptoms of depression and anxiety which were, in turn, independently linked to reduced emotional well-being. Moreover, the effect size for the anxiety pathway (ß=-0.13) was 60% larger than for depression (ß=-0.08). Dual mediation suggests depression, and especially anxiety, may be important targets for interventions seeking to mitigate the deleterious effects of discrimination. Findings have important implications for psychotherapeutic treatments and public health policy.

Lay health worker research personnel for home-based data collection in clinical and translational research: Qualitative and quantitative findings from two trials in hard-to-reach populations.

Aims: The role of lay health workers in data collection for clinical and translational research studies is not well described. We explored lay health workers as data collectors in clinical and translational research studies. We also present several methods for examining their work, i.e., qualitative interviews, fidelity checklists, and rates of unusable/missing data. Methods: We conducted 2 randomized, controlled trials that employed lay health research personnel (LHR) who were employed by community-based organizations. In one study, n = 3 Latina LHRs worked with n = 107 Latino diabetic participants. In another study, n = 6 LHR worked with n = 188 Cambodian American refugees with depression. We investigated proficiency in biological, behavioral, and psychosocial home-based data collection conducted by LHR. We also conducted in-depth interviews with lay LHR to explore their experience in this research role. Finally, we described the training, supervision, and collaboration for LHR to be successful in their research role. Results: Independent observers reported a very high degree of fidelity to technical data collection protocols (>95%) and low rates of missing/unusable data (1.5%-11%). Qualitative results show that trust, training, communication, and supervision are key and that LHR report feeling empowered by their role. LHR training included various content areas over several weeks with special attention to LHR and participant safety. Training and supervision from both the academic researchers and the staff at the community-based organizations were necessary and had to be well-coordinated. Conclusions: Carefully selected, trained, and supervised LHRs can collect sophisticated data for community-based clinical and translational research.

Secondary analysis of a randomized trial testing community health educator interventions for diabetes prevention among refugees with depression: effects on nutrition, physical activity and sleep.

BACKGROUND: Refugees have high levels of psychological distress that hamper lifestyle change efforts. We previously reported that community health educator (CHE) diabetes prevention interventions decreased HbA1c and depressive symptoms among Cambodian-American refugees with depression; this paper reports health behavior outcomes of those interventions. METHODS: Participants were aged 35-75, Khmer speaking, at risk for diabetes, and met study criteria for likely depression by either a) antidepressant medication and/or b) prolonged elevated depressive symptoms. Participants were randomized to one of three CHE interventions: 1) lifestyle intervention called Eat, Walk, Sleep (EWS), 2) EWS plus medication therapy management with a pharmacist/CHE team (EWS + MTM), or, 3) social services (SS; control). Physical activity and sleep were measured with 7 days of actigraphy. Nutrition was measured as carbohydrates as reported in a culturally tailored food frequency questionnaire. Assessments were at baseline, end point (12 months), and follow-up (15 months). RESULTS: The n = 188 participants were 78% female, average age of 55 years, half had a household income < $20,000, and modal education was 7.0 years. Individuals in the two treatment groups that received the EWS intervention significantly increased their brown rice consumption (p < .001, Cohen's d = 0.76) and their moderate-to-vigorous activity (p = .039, d = 0.32). No intervention changed sleep duration, timing, efficiency or wake after sleep onset. Across groups, individuals who increased brown rice consumption, increased vigorous activity and decreased total sleep time variability showed decreased HbA1c, with small effect sizes. CONCLUSIONS: CHEs may improve nutrition and physical activity in refugees with depression but more intensive interventions may be required to impact sleep. Improvements in all three behaviors appear to be associated with HbA1c lowering TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02502929.

Longitudinal relations of sleep quality with depressive symptoms, diabetes distress and self-efficacy in young people with type 1 diabetes.

PURPOSE: To examine the longitudinal, bidirectional associations of sleep quality with depressive symptoms, diabetes-specific distress and diabetes management self-efficacy among adolescents and young adults with type 1 diabetes. METHODS: Cross-lagged analyses used baseline, three-, six- and nine-month data from a randomized trial among 60 young people. Self-report measures included the Pittsburgh Sleep Quality Index, Center for Epidemiological Studies - Depressed Mood scale, Problem Areas in Diabetes Teen version, and Diabetes Management Self-efficacy Scale. RESULTS: Lower sleep quality at baseline was associated with higher three-month depressive symptoms (b = 0.21, p = 0.005) and lower diabetes self-efficacy (b = -0.18, p = 0.014), but not diabetes distress (b = 0.06, p = 0.403). Similar patterns were found at six and nine months. Three-month psychological functioning was not associated with six-month sleep quality. CONCLUSIONS: Among adolescents and young adults with type 1 diabetes, lower sleep quality predicted subsequent depressive symptoms and lower diabetes self-efficacy rather than vice versa. Sleep deserves a central place in diabetes care.

Evaluating the Translational Potential of Bacteriocins as an Alternative Treatment for Staphylococcus aureus Infections in Animals and Humans.

Antibiotic resistance remains a global threat to human and animal health. Staphylococcus aureus is an opportunistic pathogen that causes minor to life-threatening infections. The widespread use of antibiotics in the clinical, veterinary, and agricultural setting combined with the increasing prevalence of antibiotic-resistant S. aureus strains makes it abundantly clear that alternatives to antibiotics are urgently needed. Bacteriocins represent one potential alternative therapeutic. They are antimicrobial peptides that are produced by bacteria that are generally nontoxic and have a relatively narrow target spectrum, and they leave many commensals and most mammalian cells unperturbed. Multiple studies involving bacteriocins (e.g., nisin, epidermicin, mersacidin, and lysostaphin) have demonstrated their efficacy at eliminating or treating a wide variety of S. aureus infections in animal models. This review provides a comprehensive and updated evaluation of animal studies involving bacteriocins and highlights their translational potential. The strengths and limitations associated with bacteriocin treatments compared with traditional antibiotic therapies are evaluated, and the challenges that are involved with implementing novel therapeutics are discussed.

Community-based diabetes prevention randomized controlled trial in refugees with depression: effects on metabolic outcomes and depression.

Depression and antidepressant medications increase risk for type 2 diabetes. Cambodian-Americans have exceedingly high rates of both depression and diabetes. This paper reports outcomes of a diabetes prevention trial for Cambodian-Americans with depression. Primary outcomes were HbA1c, insulin resistance and depressive symptoms. Participants were aged 35-75, Khmer speaking, at risk for diabetes, and met study criteria for likely depression by either (a) antidepressant medication and/or (b) prolonged elevated depressive symptoms. Participants were randomized to one of three community health worker (CHW) interventions: (1) lifestyle intervention called Eat, Walk, Sleep (EWS), (2) EWS plus medication therapy management sessions with a pharmacist/CHW team to resolve drug therapy problems (EWS + MTM), or, (3) social services (SS; control). Assessments were at baseline, post-treatment (12 months), and follow-up (15 months). The n = 188 participants were 78% female, average age of 55 years, half had a household income < $20,000, and modal educational attainment was 7.0 years. Compared to the other arms, EWS + MTM showed a significant decrease in HbA1c and a trend for reduced inflammation and stress hormones. Depressive symptoms improved for EWS and EWS + MTM relative to SS. There was no change in insulin resistance. Cardiometabolic and mental health can be improved in tandem among immigrant and refugee groups.

Exposure to Starvation: Associations with HbA1c, Anthropometrics, and Trauma Symptoms Four Decades Later Among Cambodians Resettled in the USA.

BACKGROUND: Epidemiological data suggest that populations exposed to starvation show increased incidence of type 2 diabetes but these studies are limited by lack of person-level data. Cambodians resettled in the USA survived severe malnutrition during distinct historical eras. We examined the relationship of individual exposure to starvation with current HbA1c, anthropometrics, and trauma symptoms among Cambodian Americans. METHODS: Participants were excluded for extant diabetes but all had elevated risk factors for type 2 diabetes and depression. Participants identified images on a 5-point scale that best depicted their body size during four distinct periods: before 1970 (peacetime), 1970-1975 (USA bombing campaign, widespread hunger), 1975-1979 (Pol Pot regime, mass starvation), and "now" (2016-2019, resettled in the USA). They reported trauma symptoms and provided anthropometrics and a blood sample. RESULTS: The n = 189 participants were mean = 55 years old and had glycosylated hemoglobin (HbA1c) mean = 5.5%. Self-reported body size showed excellent validity by strong correlations between body thinness "now" and objectively measured waist circumference (r = -0.35), weight (r = -0.50), and body mass index (r = -0.50). Whereas there was some variability, modal self-reported body size started as normal during peacetime, became thinner during the USA bombing campaign, became emaciated during the Pol Pot regime, and rebounded to normal/slightly heavy "now." Body size during Pol Pot showed the strongest associations with long-term outcomes; thinner body size (greater starvation) was associated with higher trauma symptoms and higher HbA1c even after controlling for age, current waist circumference, and current body mass index. CONCLUSION: Greater degree of starvation was associated with higher HbA1c and trauma symptoms four decades later.

Psychological distress and health behaviours among Cambodian Americans at risk for developing diabetes.

This paper reports secondary data analysis of associations between psychological distress and health behaviours among Cambodian Americans. Data are from baseline assessments from a diabetes prevention trial. All participants met stucriteria for depression and were free of diabetes. Participants (n = 191) completed surveys, a food frequency assessment, and wore sleep and physical activity actigraphy devices for 7 days. A factor analysis of symptoms of post-traumatic stress, baksbat (a Cambodian culture-bound syndrome), depression, and anxiety yielded a single factor named 'psychological distress'. Multivariate models controlling for psychotropic medications were run for the following outcomes: sleep actigraphy, self-reported sleep, physical activity actigraphy, self-reported physical activity, nutrition, and substance use. For actigraphy, higher distress was associated with lower moderate/vigorous physical activity and higher mean variability of 24 h total sleep time. Higher distress was also associated with worse self-reported sleep quality as indicated by standard, and culturally-specific, sleep indicators. Higher distress was also associated with lower use of food labels, lower carbohydrate consumption, and higher alcohol consumption as a coping mechanism. Interventions to mitigate diabetes risk in high-distress populations may benefit from strategies to decrease psychological distress. The sequelae of complex trauma may transcend discrete psychiatric diagnoses.

Self-reported outcomes of a randomized trial comparing three community health worker interventions for diabetes prevention among Cambodian Americans with depression.

OBJECTIVE: Cambodian Americans have complex, interrelated and persistent medical and mental health problems stemming from genocide and the social determinants of health. We examined changes in multiple domains of self-reported health outcomes from a diabetes prevention trial. METHODS: Cambodian Americans with depression and high risk for diabetes (n = 188) were randomized to one of three community health worker interventions: lifestyle vs lifestyle plus medication therapy management vs social services. Assessments were at baseline, 12- and 15-months. RESULTS: The typical participant was 55 years old, female, earned below $20,000 annually, and had 7 years of education. About one-third were taking antidepressant medication and over half had elevated depressive symptoms. Relative to social services, lifestyle and lifestyle plus medication therapy management were both similarly effective at increasing diabetes knowledge, nutrition habits, sleep quality and decreasing pain; 2) lifestyle alone was superior to social services for self-reported health; and, 3) all three groups showed improved anxiety and insomnia. There were no effects on physical activity or physical functioning. CONCLUSION: Community health worker interventions have multiple benefits beyond delaying diabetes. PRACTICE IMPLICATIONS: Health promotion programs that are designed and delivered appropriately can impact even hard to reach and hard to treat groups.

Self-reported pain among Cambodian Americans with depression: patient-provider communication as an overlooked social determinant.

OBJECTIVES: Pain is common among torture survivors and refugees. Clear communication about one's pain is vital to timely and precise diagnosis and treatment but is rarely recognized as a social determinant of health. We examined whether self-reported difficulty communicating with their health care provider, along with standard social determinants, is associated with self-reported pain in Cambodian American refugees. METHODS: Secondary data analysis was conducted on n = 186 baseline assessments from a diabetes prevention trial of Cambodian Americans with depression. Bilingual, bicultural community health workers (CHWs) conducted surveys including social determinants of health and past week pain occurrence and interference. RESULTS: The sample was 78% female, modal household income = $25,000, mean age = 55 years, and mean education = 6.9 years. About one-third had private insurance and two-thirds could not speak English conversationally. The average pain score was 2.8 on a scale from 0-8 with 37% reporting no pain at all. In bivariate analyses, predictors of higher pain scores were higher difficulty understanding healthcare provider, depressive symptoms, trauma symptoms, food insecurity, and social isolation; predictors of lower pain scores were higher years of education, income, English language proficiency, social support, working, and having private insurance. In the multivariate backward elimination model only two predictors were retained: difficulty understanding healthcare provider and depressive symptoms. DISCUSSION: We propose that healthcare communication is a modifiable social determinant of health. Healthcare institutions should receive the resources necessary to secure patients' rights to clear communication including trained community health workers.

Lack of attention to sex and gender in periodontitis-related randomized clinical trials: A meta-research study.

AIM: This meta-research study aimed to investigate the level of compliance with the Sex and Gender Equity in Research (SAGER) Guidelines for the inclusion, analysis, and reporting of sex/gender, in periodontitis-related randomized controlled trials (RCTs). MATERIALS AND METHODS: Following the inclusion of RCTs related to the treatment of periodontitis published between 2018 and 2019, we applied the SAGER checklist to assess the adherence to sex/gender reporting guidelines. We used non-parametric descriptive statistics and correlation models to test the association of the dependent outcome with other variables. RESULTS: One hundred and one articles were included in the analysis. The female enrolment ranged between 30% and 94%. Twenty-six studies enrolled less than 50% of female participants. The overall SAGER score (OSS) of item fulfilment ranged between 0 and 7 items with an average of 1.9 items signifying poor guideline adherence to the SAGER guidelines. These findings were not associated with the corresponding author gender (p = .623), publication year (p = .947), and funding source (p = .133). However, a significant but negative correlation with journal impact factor (r = -0.253, p = .026) was observed. CONCLUSIONS: Sex and gender were frequently disregarded in clinical trial reporting. This oversight might limit the understanding of sex/gender differences in periodontitis-related clinical trials.

Psychometric evaluation of the Persian version of the Heart Disease Fact Questionnaire (HDFQ) in people with diabetes in Iran.

BACKGROUND AND AIMS: Public health and clinic-based educational strategies are desperately needed to stem the tide of death from heart disease among people with diabetes in low and middle-income countries. This study translated the Heart Disease Fact Questionnaire into Persian and evaluated its reliability and validity for use in Iran. METHODS: Using rigorous translation methods, the 25-item scale was administered to Persian speakers with diabetes. The scale was evaluated for content validity, construct validity and reliability. RESULTS: Participants were 268 patients with diabetes with mean age of 63.19 ± 16.61 years. The mean HDFQ score was 17.31 ± 5.11 (in the low range). Higher scores were associated with younger age, younger age of diabetes onset, higher education, higher employment position, family history of diabetes and hypertension, shorter diabetes duration, and adherence to home exercise regimens. Kuder-Richardson's reliability coefficient was good, i.e., 0.82. Confirmatory factor analysis showed that the factor loadings of all questions, except question number 25, were favorable, i.e., >0.3. Model fit indices were favorable: Chi-square statistic to degree of freedom ratio (χ2/df) = 1.82, Comparative fit index = 0.96, Tucker-Lewis Index = 0.96 and root mean square error = 0.06. CONCLUSION: After removing item #25, the Persian heart disease fact questionnaire has good validity and reliability and can be used to inform and evaluate clinical and public health educational programs aimed at decreasing risk for heart disease among Persian speakers with diabetes.

Night Eating Among Latinos With Diabetes: Exploring Associations With Heart Rate Variability, Eating Patterns, and Sleep.

OBJECTIVES: We explored associations between night eating and health outcomes in Latinos with type 2 diabetes. METHODS: Participants (n = 85) completed surveys, were measured for anthropometrics, provided blood samples, and wore Holter monitors for 24 hours to assess heart rate variability. RESULTS: Participant mean age was 60.0 years, hemoglobin A1c was 8.7%, most preferred Spanish (92%), and had less than a high school education (76%). Compared with their counterparts who denied night eating, night eaters had lower heart rate variability in the low (Cohen's d = -0.55; P = 0.04) and very-low-frequency bands (d = -0.54, P = 0.05), and reported more emotional eating (d = 0.52, P = 0.04), and poorer sleep quality (Cohen's h = 0.64). They did not differ on beverage intake or depressive symptoms. In regression that included depressive symptoms, associations between night eating and outcomes became nonsignificant. CONCLUSIONS AND IMPLICATIONS: Night eaters demonstrated worse health outcomes. If results are replicated, nutrition education for this population might focus on night eating.

Relationship of alcohol use and facial flushing to blood pressure and HbA1c among Cambodian populations with dysglycemia in the U.S. and in Cambodia.

BACKGROUND AND AIMS: Facial flushing after drinking alcohol, common among Asians, is a phenotype for genes involved in alcohol metabolism. METHODS: We investigated cross-sectional associations between flushing, alcohol use, blood pressure (BP) and HbA1c among (n = 287) Cambodians with dysglycemia in Cambodia and in the U.S. Participants were categorized as Abstainers, Flushers who drink, or Non-flushers who drink. RESULTS: Flushers and Non-flushers had similar alcohol use. Flushers had higher BP than Non-flushers and Abstainers, even after controlling for confounders. Findings were similar across countries. Drinkers had higher HbA1c than Abstainers. CONCLUSIONS: Future research should examine whether reducing alcohol improves cardiometabolic outcomes.

Tobacco use patterns and clinical outcomes in the T1D exchange.

AIMS: This study examined associations between tobacco use and diabetes outcomes using the T1D Exchange Registry. METHODS: Adult participants (N = 933) completed standardized questionnaires including self-reported outcomes: past year serious hypoglycemic and diabetic ketoacidosis episodes, diabetes self-care, diabetes distress, and self-monitoring of blood glucose. Chart-extracted outcomes included HbA1c, nephrology and neuropathy diagnoses, and BMI. We examined the relation of tobacco use status (never, former, current) and frequency of use (daily versus less than daily) to these outcomes. RESULTS: The majority had never used tobacco (55%, n = 515); 27% (n = 252) were former users and 18% (n = 166) were current users (with 31% using daily). Tobacco status was associated with HbA1c, BMI, self-care, distress, and blood glucose monitoring frequency. Across most outcomes, current users evidenced worse values relative to never users, and former users were largely similar to never users. Daily use was associated with significantly worse outcomes on HbA1c, diabetes self-care, and distress scores relative to less than daily use. CONCLUSIONS: These cross-sectional comparisons suggest that current tobacco use is associated with worse status on important clinical diabetes indicators. Former users did not evidence these deleterious associations. Findings point to potential diabetes-specific motivators that could inform tobacco cessation interventions.

Risk factors for drug therapy problems among Cambodian Americans with complex needs: a cross-sectional, observational study.

BACKGROUND: Pharmaceutical drug therapy problems (DTPs) are a major public health problem. We examined patient-level risk factors for DTPs among Cambodian Americans. METHODS: Community health workers (CHWs) verbally administered surveys and completed a detailed medication review form with participants. A doctoral-level pharmacist reviewed the form with the patient and CHW to determine DTP number and type (appropriateness, effectiveness, safety, and adherence). RESULTS: Participants (n = 63) averaged 55 years old, 6 years of education, 52% were married, 87% spoke Khmer at home, with modal household income <$20,000 (41%). The percentage of participants with DTPs was: 45% appropriateness, 25% effectiveness, 64% safety, and 30% adherence, averaging 3.7 DTPs per patient. In multiple regressions, patient characteristics uniquely predicted each type of DTP. In a multiple regression controlling for number of medications, being married reduced total DTPs (IRR = 0.70) and being depressed increased total DTPs (IRR = 1.26). CONCLUSIONS: Vulnerable patients should be prioritized for pharmacist/CHW teams to identify DTPs.Trial registration: ClinicalTrials.gov identifier: NCT02502929.

Pharmacists and community health workers improve medication-related process outcomes among Cambodian Americans with depression and risk for diabetes.

BACKGROUND: Cambodian Americans have high rates of cardiometabolic and psychiatric disorders and disadvantaged social determinants of health (SDOH). These factors can make it challenging to resolve drug therapy problems (DTPs) and improve medication-related outcomes. This manuscript reports planned analyses from a randomized controlled trial in which participants were randomized to one of 3 treatment arms: (1) community health worker (CHW)-delivered lifestyle intervention called Eat, Walk, sleep (EWS), (2) EWS plus pharmacist/CHW-delivered medication therapy management (EWS + MTM), or (3) social services (SS: control). OBJECTIVES: We compared the 3 arms on changes in self-reported medication adherence, barriers, and beliefs. Within the EWS + MTM arm only, we assessed the impact of EWS + MTM on DTP resolution and examined predictors of DTP resolution. METHODS: Cambodian Americans at the age of 35-75 years at high risk of developing diabetes and meeting the criteria for likely depression (N = 188) were randomized (EWS, n = 67; EWS + MTM, n = 63; SS, n = 50; control). For all participants, self-reported surveys were collected at baseline, 12 months, and 15 months. DTPs were assessed on the same schedule but only for participants in the EWS + MTM. RESULTS: All 3 groups reported a significant decrease in barriers to taking medications. Compared with the other arms, the EWS + MTM arm reported a decrease in forgetting to take medications at 15 months. In the EWS + MTM arm, mean DTPs per patient was 6.57 and 84% of DTPs were resolved. SDOH predictors of DTP resolution included years of education (odds ratio [OR] 0.94, P = 0.016), ability to write English (OR 0.73, P = 0.015), difficulty communicating with provider (OR 1.39, P < 0.001), private insurance (OR 1.99, P = 0.030), disability (OR 0.51, P = 0.008), and years living under Pol Pot (OR 0.66, P = 0.045). Medication barriers at baseline predicted DTP resolution (OR 0.79, P = 0.019) such that each additional barrier was associated with a 21% reduction (1-0.79) in the odds of having a resolution. CONCLUSION: CHWs can reduce medications barriers and help pharmacists reduce DTPs in disadvantaged populations.

Lifestyles Under Lockdown: A Scoping Review of International Studies on Type 2 Diabetes Self-Management Behaviors During COVID-19.

Background: The effect of the COVID-19 pandemic on diabetes self-management behaviors is unclear. Objectives: This paper is a scoping review of studies examining health behaviors among people with type 2 diabetes during the COVID-19 pandemic. Eligibility Criteria: We searched articles available in English using the Search terms "COVID" and "diabetes", and, separately, each of the following terms: "lifestyle", "health behavior", "self-care", "self-management", "adherence", "compliance", "eating", "diet", "physical activity", "exercise", "sleep", "self-monitoring of blood glucose", or "continuous glucose monitoring". Sources of Evidence: We searched PubMed, PsychInfo, and Google Scholar databases from December 2019 through August 2021. Charting Methods: Data were extracted by 4 calibrated reviewers and study elements were charted. Results: The search identified 1,710 articles. After screening for relevance and eligibility, 24 articles were included in this review. Findings show the strongest evidence for reduced physical activity and stable glucose monitoring and substance use. There was equivocal evidence for deleterious changes in sleep, diet, and medication intake. With one minor exception, there was no evidence for favorable changes in health behaviors. Limitations of the literature include small samples, predominantly cross-sectional study designs, reliance on retrospective self-reports, sampling through social media, and few standardized measures. Conclusions: Early studies of health behaviors among people with type 2 diabetes during the COVID-19 pandemic suggest a need for novel interventions to support diabetes self-management, especially targeting physical activity. Future studies should go beyond documenting changes in health behaviors and examine predictors of change over time.
