Blood extracellular vesicles carrying brain-specific mRNAs are potential biomarkers for detecting gene expression changes in the female brain.

The absence of non-invasive tests that can monitor the status of the brain is a major obstacle for psychiatric care. In order to address this need, we assessed the feasibility of using tissue-specific gene expression to determine the origin of extracellular vesicle (EV) mRNAs in peripheral blood. Using the placenta as a model, we discovered that 26 messenger RNAs that are specifically expressed in the placenta are present in EVs circulating in maternal blood. Twenty-three of these transcripts were either exclusively or highly expressed in maternal blood during pregnancy only and not in the postpartum period, verifying the feasibility of using tissue-specific gene expression to infer the tissue of origin for EV mRNAs. Using the same bioinformatic approach, which provides better specificity than isolating L1 cell-adhesion molecule containing EVs, we discovered that 181 mRNAs that are specifically expressed in the female brain are also present in EVs circulating in maternal blood. Gene set enrichment analysis revealed that these transcripts, which are involved in synaptic functions and myelination, are enriched for genes implicated in mood disorders, schizophrenia, and substance use disorders. The EV mRNA levels of 13 of these female brain-specific transcripts are associated with postpartum depression (adjusted p-vals = 3 × 10-5 to 0.08), raising the possibility that they can be used to infer the state of the brain. In order to determine the extent to which EV mRNAs reflect transcription in the brain, we compared mRNAs isolated from cells and EVs in an iPSC-derived brain microphysiological system differentiated for 3 and 9 weeks. We discovered that, although cellular and extracellular mRNA levels are not identical, they do correlate, and it is possible to extrapolate cellular RNA expression changes in the brain via EV mRNA levels. Our findings bring EV mRNAs to the forefront of peripheral biomarker development efforts in psychiatric diseases by demonstrating the feasibility of inferring transcriptional changes in the brain via blood EV mRNA levels.

Grandmaternal pre-pregnancy body mass index and infant birthweight: a mediation analysis of maternal pre-pregnancy body mass index.

The objectives of this study were to examine the total effect of grandmaternal [G0] pre-pregnancy body mass index (BMI) on infant [G2] birthweight z-score and to quantify the mediation role of maternal [G1] pre-pregnancy BMI. Data were extracted from the Nova Scotia 3G Multigenerational Cohort. The association between G0 pre-pregnancy BMI and G2 birthweight z-score and the mediated effect by G1 pre-pregnancy BMI were estimated using g-computation with adjustment for confounders identified using a directed acyclic graph and accounting for intermediate confounding. 20822 G1-G2 dyads from 18450 G0 were included. Relative to G0 normal weight, G0 underweight decreased mean G2 birthweight z-score (-0.11, 95% confidence interval (CI) -0.20, -0.030), while G0 overweight and obesity increased mean G2 birthweight z-score (0.091 [95% CI 0.034, 0.15] and 0.22 [95% CI 0.11, 0.33]). G1 pre-pregnancy BMI partly mediated the association, with the largest effect size observed for G0 obesity (0.11, 95% CI 0.080, 0.14). Estimates of the direct effect were close to the null. In conclusion, grandmaternal pre-pregnancy BMI was associated with infant birthweight z-score. Maternal pre-pregnancy BMI partly mediated the association, suggesting that factors related to BMI may play an important role in the transmission of weight across the maternal line.

Altered extracellular mRNA communication in postpartum depression is associated with decreased autophagy.

We investigated whether extracellular RNA communication, which is a recently discovered mode of intercellular communication that is involved in a variety of important biological processes including pregnancy, is associated with postpartum depression (PPD). Extracellular RNA communication is increased during pregnancy and is involved in embryo implantation, uterine spiral artery remodeling, parturition, preterm birth, immunity, and the inflammatory response. Since immune anomalies are associated with PPD, we characterized the mRNA content of extracellular vesicles (EV) in a cohort of prospectively collected blood plasma samples at six time-points throughout pregnancy and the postpartum (2nd trimester, 3rd trimester, 2 weeks postpartum, 6 weeks postpartum, 3 months postpartum, and 6 months postpartum) in an academic medical setting from women who went on to develop PPD (N = 7, defined as euthymic in pregnancy with postpartum-onset depressive symptoms assessed by Edinburgh Postnatal Depression Scale ≥13 at any postpartum time point) and matched unaffected controls (N = 7, defined as euthymic throughout pregnancy and postpartum). Blood samples were available for all participants at the T2 and W6 timepoints, with fewer samples available at other time points. This analysis revealed that EV mRNA levels during pregnancy and the postpartum period were extensively altered in women who went on to develop PPD. Gene set enrichment analysis revealed that mRNAs associated with autophagy were decreased in PPD cases. In contrast, EV mRNAs from ribosomes and mitochondria, two organelles that are selectively targeted by autophagy, were elevated in PPD cases. Cellular deconvolution analysis discovered that EV mRNAs associated with PPD originated from monocytes and macrophages. Quantitative PCR analysis for four relevant genes in another cohort replicated these findings and confirmed that extracellular RNA levels are altered in PPD. We demonstrate that EV mRNA communication is robustly altered during pregnancy and the postpartum period in women who go on to develop PPD. Our work also establishes a direct link between reduced autophagy and PPD in patient samples. These data warrant investigating the feasibility of developing EV mRNA based biomarkers and therapeutic agents for PPD.

Expression of the GFP-mammalian pleckstrin homology (PH) domain of the phospholipase C δ1 in Saccharomyces cerevisiae BY4741.

BACKGROUND: Pleckstrin homology (PH) domains are common modules of ∼120 amino acids found in proteins involved in signalling, cytoskeletal organization, membrane transport, and modification of phospholipids. Previous live cell studies have involved the use of the green-fluorescent protein (GFP) labelling of PH-domain of phospholipase C δ1 (PLC δ1) to study the interactions of molecules at the membrane interface. METHODS AND RESULTS: For this study, the aim was to construct and express the GFP-PH domain of PLC δ1 in the Saccharomyces cerevisiae BY4741. The transformants expressing GFP-PH domain of PLC δ1 displayed localised fluorescence to the cell periphery (plasma membrane) while the negative control expressed GFP within the cytoplasm only. No GFP was observed in the non-transformed yeast cells. CONCLUSIONS: Thus, this technique could be useful in future molecular interactions studies targeted specifically at the yeast cell membrane interface in live yeast cells.

Premenstrual symptoms across the lifespan in an international sample: data from a mobile application.

Premenstrual symptoms, including physical and mood symptoms, affect a large proportion of women worldwide. Data on premenstrual symptoms across nations and age groups is limited. In the present study, we leveraged a large international dataset to explore patterns in premenstrual symptom frequency with age. A survey was administered to users of the Flo mobile application (app), aged 18 to 55. The survey queried app users about a range of premenstrual symptoms. Respondents were asked whether they experienced each symptom every menstrual cycle, some cycles, or never. Age was also captured and categorized as 18-27, 28-37, 38-47, 48-55. Data was summarized and Pearson's chi square test for count data assessed differences in symptom frequency by age group. A sample of 238,114 app users from 140 countries responded to the survey. The most common symptoms reported were food cravings (85.28%), mood swings or anxiety (64.18%), and fatigue (57.3%). Absentmindedness, low libido, sleep changes, gastrointestinal symptoms, weight gain, headaches, sweating or hot flashes, fatigue, hair changes, rashes, and swelling were significantly more frequent with increasing age (p's < 0.001). Mood swings and anxiety did not vary by age group. Of the respondents, 28.61% reported that premenstrual symptoms interfered with their everyday life each menstrual cycle. In a large international sample, the majority of women reported premenstrual food cravings, mood changes, and fatigue every menstrual cycle. Mood symptoms did not vary by age group, suggesting that premenstrual mood changes are a persistent issue among women of reproductive age.

Allopregnanolone and depression and anxiety symptoms across the peripartum: an exploratory study.

Recent research has implicated allopregnanolone (ALLO), a neuroactive steroid and metabolite of progesterone, in perinatal mood and anxiety symptoms. We sought to add to the limited literature examining ALLO and mood and anxiety at multiple time points across the peripartum. We measured mood and anxiety symptoms and ALLO levels by ELISA at the second and third trimester (T2 and T3) and week 6 postpartum (W6) in N = 73 women with prior histories of mood and/or anxiety disorders and N = 38 healthy controls. Analytic methods included multivariate and logistic regressions with linear mixed effect models. Among all participants (N = 111), higher ALLO levels at W6 were associated with higher depression and anxiety scores: each one unit increase in log ALLO at W6 was associated with a 2.54 point increase on the Edinburgh Postnatal Depression Scale (EPDS) (95% CI: 0.73 to 4.33) and an 8.0 point increase on the Perinatal Anxiety Screening Scale (PASS) (95% CI: 3.82 to 12.6). In addition, the nature of the relationship between log ALLO level and psychological measures changed across time; from T2 to W6 for EPDS, ß = 3.73 (95% CI:1.16, 6.30), p = 0.0045; for PASS ß = 9.78 (95% CI:3.77, 15.79), p = 0.0014); from T3 to W6, for (EPDS, ß = 2.52 (95% CI:0.08, 4.96), p = 0.043; for PASS ß = 7.33 (95% CI:1.63, 13.02), p = 0.018). The relationship of log ALLO to mood and anxiety symptoms was the same among women with and without psychiatric histories. Our exploratory findings indicate that the relationship between ALLO and mood and anxiety symptoms may change across the peripartum.

Nutritional Considerations for the Power Athlete.

ABSTRACT: Nutrition is a significant factor in a power athlete's ability to achieve hypertrophy, strength, lean body mass, and overall performance goals. Optimizing an athlete's macronutrient balance, timing of intake, and hydration is essential for advancing performance and should be fluid as the athlete transitions between cycles of training, matching nutrient requirements to intensity of training throughout periodization. Supplement use can help athletes meet their performance and nutrition goals when used as an adjunct to a well-chosen diet, both by direct ergogenic effect and by reducing risk of illness or injury. Educating athletes and coaches on an optimal nutrition plan to support training, performance, and health is critical to prevent the negative effects that may come from poor diet, dangerous weight cutting practices, and relative energy deficiency in sport.

Hospitality Towards People with Mental Illness in the Church: a Cross-cultural Qualitative Study.

Mental illness is a prevalent concern that affects Christian churches in North America in significant ways. Previous studies on the relationship between mental illness and the church have found that beliefs and practices within the church can contribute to stigma towards people with mental illness. Yet, the typical experience of people with mental illness who attend church has been found to be positive, suggesting that there are considerable resources within the church for supporting those who experience mental health problems. One such resource is the concept of hospitality, which promotes a sense of belonging for those with mental illness in the church. This qualitative study advances the construct of hospitality as a helpful paradigm for addressing mental health needs within the church, capturing perspectives and practices that are currently in place or seen as necessary by church attendees. The study methodology also emphasized the need to incorporate cultural considerations that are appropriate for the racial and ethnic make-up of particular churches. Semistructured focus group interviews were conducted with participants from eight churches that were either predominantly African American, Asian American, Latinx, or multi-ethnic. Findings resulting from content analysis of transcripts indicated that hospitality was a broadly helpful construct for addressing mental health concerns in the church, though some cultural differences existed in the understanding and application of hospitality. Both the interface of the findings with the existing scholarly literature and the relevance of findings for church leaders are discussed.

The implications of missed or misinterpreted cases of pancreatic ductal adenocarcinoma on imaging: a multi-centered population-based study.

OBJECTIVES: To assess the proportion of missed/misinterpreted imaging examinations of pancreatic ductal adenocarcinoma (PDAC), and their association with the diagnostic interval and survival. METHODS: Two hundred fifty-seven patients (mean age, 71.8 years) diagnosed with PDAC in 2014-2015 were identified from the Nova Scotia Cancer Registry. Demographics, stage, tumor location, and dates of initial presentation, diagnosis, and, if applicable, surgery and death were recorded. US, CT, and MRI examinations during the diagnostic interval were independently graded by two radiologists using the RADPEER system; discordance was resolved in consensus. Mean diagnostic interval and survival were compared amongst RADPEER groups (one-way ANOVA). Kaplan-Meier analysis was performed for age (< 65, 65-79, ≥ 80), sex, tumor location (proximal/distal), stage (I-IV), surgery (yes/no), chemotherapy (yes/no), and RADPEER score (1-3). Association between these covariates and survival was assessed (multivariate Cox proportion hazards model). RESULTS: RADPEER 1-3 scores were assigned to 191, 27, and 39 patients, respectively. Mean diagnostic intervals were 53, 86, and 192 days, respectively (p = 0.018). There were only 3/257 (1.2%) survivors. Mean survival was not different between groups (p = 0.43). Kaplan-Meier analysis showed worse survival in RADPEER 1-2 (p = 0.007), older age (p < 0.001), distal PDAC (p = 0.016), stage (p < 0.0001), and no surgery (p < 0.001); survival was not different with sex (p = 0.083). Cox analysis showed better survival in RADPEER 3 (p = 0.005), women (p = 0.002), surgical patients (p < 0.001), and chemotherapy (p < 0.001), and worse survival in stage IV (p = 0.006). CONCLUSION: Imaging-related delays occurred in one-fourth of patients and were associated with longer diagnostic intervals but not worse survival, potentially due to overall poor survival in the cohort. KEY POINTS: • One-fourth of patients (66/257, 25.7%) with pancreatic ductal adenocarcinoma (PDAC) underwent imaging examinations that demonstrated manifestations of the disease, but findings were either missed or misinterpreted; RADPEER 2 and 3 scores were assigned to 10.5% and 15.2% of patients, respectively. • Patients with imaging examinations assigned RADPEER 3 scores were associated with significantly longer diagnostic intervals (192 ± 323 days) than RADPEER 1 (53 ± 86 days) and RADPEER 2 (86 ± 120 days) (p < 0.001). • Imaging-related diagnostic delays were not associated with worse survival; however, this may have been confounded by the overall poor survival in our cohort (only 3/257 (1.2%) survivors).

Polycystic Ovary Syndrome, Affective Symptoms, and Neuroactive Steroids: a Focus on Allopregnanolone.

PURPOSE OF REVIEW: To provide an overview of existing studies on alterations in gonadal and neuroactive steroids (NASs) and mood symptoms among women with polycystic ovary syndrome (PCOS). RECENT FINDINGS: Recent studies have demonstrated a previously underappreciated association between PCOS and comorbid depression and anxiety. However, most studies on affective symptoms among women with PCOS have been cross-sectional, limiting our knowledge about fluctuations in symptoms over the menstrual cycle and reproductive lifespan for women with PCOS, as well as the potential interplay between NAS alterations and mood symptoms. Changes in the NAS allopregnanolone (ALLO) have been implicated in several reproductive-related psychiatric disorders (e.g., premenstrual dysphoric disorder (PMDD) and postpartum depression (PPD)) as well as in normal reproductive functioning, warranting further investigation for its potential role in the psychiatric symptoms observed in women with PCOS. Prospective studies evaluating associations between psychiatric symptoms and NAS are needed to elucidate the biological causes of the increased rates of psychiatric symptoms among women with PCOS and inform clinical treatment. ALLO, with its role in normal reproductive function, menstrual dysregulation among women with PCOS, and reproductive-related psychiatric conditions, makes it a particularly intriguing candidate for future investigation.

Lack of psychotropic medication changes among mood disordered women across the peripartum period.

OBJECTIVE: Peripartum depression is a leading contributor to peripartum morbidity and mortality. Despite the evidence for relative safety, many patients and providers remain reluctant to use or modify psychotropics in the peripartum period. We hypothesized that depressed women in the peripartum period taking psychiatric medications would not experience dose adjustments. METHODS: Women with a prior history of either Major Depressive Disorder or Bipolar Affective Disorder were followed through pregnancy and the postpartum period (N = 229). Depressive symptoms were measured with the Edinburgh Postnatal Depression Scale (EPDS), with a score ≥ 13 indicating likely depression. Data analysis included descriptive statistics, chi-square tests, and logistic regression. RESULTS: Antepartum depression was more common than postpartum depression (PPD; 29% vs. 20%); 38% of women with antepartum depression also had PPD. Regression analysis revealed that, although depressed women in pregnancy were not more likely to have a dose adjustment than nondepressed women (OR: 1.9, 95% CI: 0.8-4.6), depressed women in the postpartum were more likely to receive a medication change than nondepressed women (OR: 6.3, 95% CI: 2.0-20.4). CONCLUSIONS: In a naturalistic study, more medication adjustments for depression occurred in the postpartum than in pregnancy. This may indicate that antepartum depression is undertreated.

Pathophysiological mechanisms implicated in postpartum depression.

This review aims to summarize the diverse proposed pathophysiological mechanisms contributing to postpartum depression, highlighting both clinical and basic science research findings. The risk factors for developing postpartum depression are discussed, which may provide insight into potential neurobiological underpinnings. The evidence supporting a role for neuroendocrine changes, neuroinflammation, neurotransmitter alterations, circuit dysfunction, and the involvement of genetics and epigenetics in the pathophysiology of postpartum depression are discussed. This review integrates clinical and preclinical findings and highlights the diversity in the patient population, in which numerous pathophysiological changes may contribute to this disorder. Finally, we attempt to integrate these findings to understand how diverse neurobiological changes may contribute to a common pathological phenotype. This review is meant to serve as a comprehensive resource reviewing the proposed pathophysiological mechanisms underlying postpartum depression.

Assessing breast cancer risk within the general screening population: developing a breast cancer risk model to identify higher risk women at mammographic screening.

OBJECTIVES: To develop a breast cancer risk model to identify women at mammographic screening who are at higher risk of breast cancer within the general screening population. METHODS: This retrospective nested case-control study used data from a population-based breast screening program (2009-2015). All women aged 40-75 diagnosed with screen-detected or interval breast cancer (n = 1882) were frequency-matched 3:1 on age and screen-year with women without screen-detected breast cancer (n = 5888). Image-derived risk factors from the screening mammogram (percent mammographic density [PMD], breast volume, age) were combined with core biopsy history, first-degree family history, and other clinical risk factors in risk models. Model performance was assessed using the area under the receiver operating characteristic curve (AUC). Classifiers assigning women to low- versus high-risk deciles were derived from risk models. Agreement between classifiers was assessed using a weighted kappa. RESULTS: The AUC was 0.597 for a risk model including only image-derived risk factors. The successive addition of core biopsy and family history significantly improved performance (AUC = 0.660, p < 0.001 and AUC = 0.664, p = 0.04, respectively). Adding the three remaining risk factors did not further improve performance (AUC = 0.665, p = 0.45). There was almost perfect agreement (kappa = 0.97) between risk assessments based on a classifier derived from image-derived risk factors, core biopsy, and family history compared with those derived from a model including all available risk factors. CONCLUSIONS: Women in the general screening population can be risk-stratified at time of screen using a simple model based on age, PMD, breast volume, and biopsy and family history. KEY POINTS: • A breast cancer risk model based on three image-derived risk factors as well as core biopsy and first-degree family history can provide current risk estimates at time of screen. • Risk estimates generated from a combination of image-derived risk factors, core biopsy history, and first-degree family history may be more valid than risk estimates that rely on extensive self-reported risk factors. • A simple breast cancer risk model can avoid extensive clinical risk factor data collection.

E4206: AMG 706 and Octreotide in Patients with Low-Grade Neuroendocrine Tumors.

LESSONS LEARNED: Rate of progression-free survival at a particular point in time, i.e., a landmark analysis, is a difficult endpoint for a heterogenous malignancy such as neuroendocrine cancer.Landmark analyses can also be complicated by evolution in the standard of care during the conduct of a clinical trial.Improvements in biomarker development would be useful in developing future clinical trials in NET to better tailor individualized therapies and assess for possible efficacy endpoints. BACKGROUND: Neuroendocrine tumors (NETs) are rare malignancies of the gastrointestinal (GI) tract that are highly vascularized and overexpress vascular-endothelial growth factor (VEGF). Sunitinib has demonstrated efficacy in the pancreatic subset of NET. This study explored the activity of another oral VEGF inhibitor, AMG 706 or motesanib, a multikinase inhibitor that targets receptor tyrosine kinases, including VEGFR1, VEGFR2, VEGFR3, KIT, RET, and PDGFR (IC50s = 2, 3, 6, 8, 59, and 84 nM, respectively). METHODS: This was a single-arm, first-line, phase II study run through the Eastern Cooperative Oncology Group. Patients with low-grade NET (as defined by central confirmation of Ki-67 of 0%-2%) were administered a flat dose of 125 mg per day orally combined with octreotide long acting-repeatable (LAR) for patients who had been on a stable dose. The primary objective was to determine the 4-month progression-free survival (PFS). RESULTS: Forty-four patients were evaluated per protocol. The 4-month PFS was 78.5%. The partial response rate was 13.6% (6/44), stable disease was 54.5% (24/44), 9.1% (4/44) had progressive disease, and 10/44 were not evaluable for response. Common toxicities included fatigue, hypertension, nausea, and headache, and most were grade 1-2. Median PFS was 8.7 months, and overall survival was 27.5 months. CONCLUSION: Motesanib (AMG 706) demonstrated a 4-month PFS that met the per-protocol definition of efficacy. Fatigue and hypertension were the most common toxicities, and few grade 3-4 toxicities were encountered. The progression-free survival of 8.7 months in all NETs merits further study.

Neuroactive Steroids and Perinatal Depression: a Review of Recent Literature.

PURPOSE OF REVIEW: The purpose of this review is to provide a theoretical explanation and a review of the recent literature concerning the role of neuroactive steroids in perinatal depression, and to use this information to suggest future directions of research. RECENT FINDINGS: The bulk of the evidence on neuroactive steroids in perinatal depression concerns allopregnanolone. Recent studies have been mixed, with some studies finding a direct correlation between lower levels of allopregnanolone and increased depressive symptoms but other studies finding no relationship. Evidence concerning other neuroactive steroids and perinatal depression is sparse. Additional research is needed with larger sample sizes and better characterization across the perinatal period (rather than cross-sectionally). Because some studies point to a lag between neuroactive steroid dysregulation and subsequent symptoms, future research should consider interactions with other aspects of neuroactive steroid physiology, such as synthetic enzymes or receptor plasticity.

The plant defensin NaD1 introduces membrane disorder through a specific interaction with the lipid, phosphatidylinositol 4,5 bisphosphate.

Plant defensins interact with phospholipids in bilayers as part of their cytotoxic activity. Solanaceous class II defensins with the loop 5 sequence pattern "S-[KR]-[ILVQ]-[ILVQ]-[KR]-[KR]" interact with PI(4,5)P2. Here, the prototypical defensin of this class, NaD1, is used to characterise the biophysical interactions between these defensins and phospholipid bilayers. Binding of NaD1 to bilayers containing PI(4,5)P2 occurs rapidly and the interaction is very strong. Dual polarisation interferometry revealed that NaD1 does not dissociate from bilayers containing PI(4,5)P2. Binding of NaD1 to bilayers with or without PI(4,5)P2 induced disorder in the bilayer. However, permeabilisation assays revealed that NaD1 only permeabilised liposomes with PI(4,5)P2 in the bilayer, suggesting a role for this protein-lipid interaction in the plasma membrane permeabilising activity of this defensin. No defensins in the available databases have the PI(4,5)P2 binding sequence outside the solanaceous class II defensins, leading to the hypothesis that PI(4,5)P2 binding co-evolved with the C-terminal propeptide to protect the host cell against the effects of the tight binding of these defensins to their cognate lipid as they travel along the secretory pathway. This data has allowed us to develop a new model to explain how this class of defensins permeabilises plasma membranes to kill target cells.

Reproductive Affective Disorders: a Review of the Genetic Evidence for Premenstrual Dysphoric Disorder and Postpartum Depression.

PURPOSE OF REVIEW: The purpose of this study is to review and summarize the literature exploring the genetic basis for premenstrual dysphoric disorder (PMDD) and postpartum depression (PPD). RECENT FINDINGS: There is more evidence for a genetic basis for PPD than for PMDD, but only when PPD is defined as beginning in the immediate postpartum time period. Familial, genome-wide linkage and association studies, and candidate gene studies, most in the past 10 years, have examined the genetic etiology of reproductive affective disorders, including PMDD and PPD. The most commonly studied genes include SERT, COMT, MAOA, BDNF, and ESR1 and 2. This qualitative review of the recent literature finds limited evidence so far for the genetic basis for PMDD, with both familial and candidate gene studies having negative or conflicting results. Evidence is stronger for the genetic basis for PPD, with positive associations found in family studies and in several genes associated with major depression as well as genes involved in estrogen signaling but only when PPD onset is shortly after delivery. Epigenetic biomarkers on genes responsive to estrogen have also been found to predict PPD. Our findings underscore the need for additional studies with larger samples, as well as the crucial importance of timing in the definition of PPD for genetic studies.

The Prevalence and Specificity of Depression Diagnosis in a Clinic-Based Population of Adults With Type 2 Diabetes Mellitus.

OBJECTIVE: To estimate the crude prevalence of minor depressive disorder (MinD) in a clinic-based population of adults with type 2 diabetes. METHODS: We screened a clinical sample of 702 adults with type 2 diabetes for depressive symptoms using the Patient Health Questionnaire-2 and performed a structured diagnostic psychiatric interview on 52 screen-positive and a convenience sample of 51 screen-negative individuals. Depressive disorder diagnoses were made using Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) Text Revised criteria and categorized as MinD, major depressive disorder (MDD), or no depressive disorder. We estimated prevalence of MinD and MDD and derived 95% CIs. RESULTS: The crude prevalence of current, past, and current or past MinD was 4.3% (95% CI: 0.9-9.2%), 9.6% (95% CI: 3.9-15.9%), and 13.9% (95% CI: 7.7-21.2%), respectively. The crude prevalence of current, past, and current or past MDD was slightly higher-5.0% (95% CI: 1.9-9.4%), 12.0% (95% CI: 6.1-19.5%), and 17.0% (95% CI: 10.1-24.8%), respectively. There was a high prevalence of coexisting anxiety disorders in individuals with MinD (42.2%) and MDD (8.1%). Hemoglobin A1c levels were not significantly different in individuals with MinD or MDD compared to those without a depressive disorder. CONCLUSIONS: MinD is comparably prevalent to MDD in patients with type 2 diabetes; both disorders are associated with concomitant anxiety disorders. MinD is not included in the DSM-5; however, our data support continuing to examine patients with chronic medical conditions for MinD.

"It's Kind of a Dichotomy": Thoughts Related to Calling and Purpose from Pastors Working and Counseling in Urban Resource-Poor Communities.

Pastors serving low-income urban areas are first-responders to emotional issues by default, since fewer mental health resources are available. Thus, it is important to understand how pastors serving urban resource-poor areas reflect on their counseling role. Forty-eight Black, Hispanic, and White pastors with urban congregations in Los Angeles or Chicago reflect on their pastoral calling and its relation to their counseling role. Through phenomenology, the pastors' lived experiences as they counseled in an urban context were explored. Analysis revealed complex feelings about their counseling role in light of their resource-poor environments. Recommendations are provided based on the findings.
