The prevalence of painful physical symptoms in major depressive disorder: A systematic review and meta-analysis of observational studies

Impact of painful physical symptoms on first-episode major depressive disorder in adults with subthreshold depressive symptoms: A prospective cohort study

OBJECTIVE

To investigate the impact of baseline painful physical symptoms (PPS) on subsequent first-episode major depressive disorder (MDD) in adults with subthreshold depressive symptoms, including subgroup analyses to assess whether the associations differ in individuals with and without physical diseases.

METHODS

A total of 2343 adults with subthreshold depressive symptoms were recruited at 34 primary health care centers. PPS were measured at baseline. First-episode MDD during follow-up was diagnosed by professional psychiatrists using the Mini-International Neuropsychiatric Interview.

RESULTS

Baseline PPS showed independent impacts on first-episode MDD in adults with subthreshold depressive symptoms without physical diseases, but not in those with physical diseases. A non-linear association (P < 0.001) was observed between PPS burden and the risk of first-episode MDD. The HRs for first-episode MDD exhibited a rapidly increasing trend between PPS burden scores of 10-16, and maintained consistently high when scores exceeded 16. The analyses for specific PPS revealed that headache, neck pain, and heart or chest pain were independently associated with first-episode MDD in participants without physical diseases, the HRs were 1.57 (1.15-2.36), 1.53 (1.02-2.30), and 1.69 (1.14-2.50), respectively. Further network analysis demonstrated that heart or chest pain serves as a bridge symptom among the seven specific PPS and first-episode MDD in those without physical diseases.

CONCLUSION

PPS burden and heart or chest pain may be significant indicators for first-episode MDD in adults with subthreshold depressive symptoms without physical diseases. Future studies should investigate whether interventions targeting PPS can prevent episode MDD in this subthreshold population.

Multimorbidity and Depressive Symptoms in Older Adults: A Contextual Approach

BACKGROUND AND OBJECTIVES

Among older adults, depressive symptoms increase with each chronic illness; however, specific disease-related stressors (e.g., pain) and contextual moderators (interpersonal, sociocultural, temporal) of this relationship remain understudied. We explored disease-related stressors associated with depressive symptoms and moderating effects of contextual factors on this relationship, guided by a social ecological framework.

RESEARCH DESIGN AND METHODS

Adults ≥62 years with multimorbidity (n = 366) completed validated scales assessing diagnoses, disease-related stressors (pain intensity, subjective cognitive function, physical function, somatic symptoms), and depressive symptoms. Moderators included age, expectations regarding aging, perceived social support, and difficulty affording medications. Data were analyzed using structural equation modeling.

RESULTS

Participants were 62-88 years old, with several comorbidities (M = 3.5; range: 2-9). As hypothesized, disease-related stressors were associated with depressive symptoms (b = 0.64, SE = 0.04, p < .001). The effect of disease-related stressors on depressive symptoms was greater among those reporting low social support (B = 0.70, SE = 0.06, p < .001) than for those reporting high social support (B = 0.46, SE = 0.06, p < .001). The negative effect of disease-related stressors on depressive symptoms was stronger for those with poorer expectations of aging (B = 0.68, SE = 0.07, p < .001), compared to those with more positive expectations (B = 0.47, SE = 0.06, p < .001). Age and difficulties affording medications were not significant moderators.

DISCUSSION AND IMPLICATIONS

Garnering social support and addressing low expectations for aging may prevent the detrimental effect of multimorbidity on mental health.

The course of insomnia symptoms during the acute treatment of major depressive disorder: A CAN-BIND-1 report

Despite considerable efforts to study the relationship between insomnia and depression, there is minimal research investigating whether insomnia symptoms change over time during a course of antidepressant pharmacotherapy. This study investigated the course of insomnia symptoms during the acute treatment of major depressive disorder (MDD) using a secondary analysis of data from MDD patients (N = 180) who were treated with open-label escitalopram (10-20 mg/day) for 8-weeks. Montgomery-Asberg Depression Rating Scale without sleep item (modified-MADRS) assessed depression and Self-reported Quick Inventory Depressive Scale (QIDS-SR) measured subjective sleep-onset, mid-nocturnal, and early-morning insomnia throughout 8-weeks of treatment. Pittsburgh Sleep Quality Index (PSQI) was used to assess subjective sleep quality, duration, onset latency, and efficiency throughout 8-weeks of treatment. Remission of depression was defined as modified-MADRS ≤10 at week-8. Mixed model repeated measures (MMRMs) were conducted with remission status as an independent variable and each sleep variable as a dependent variable. MMRMs demonstrated that remitters had significantly lower QIDS-SR sleep-onset and mid-nocturnal insomnia scores as well as a significantly lower PSQI sleep quality score than non-remitters throughout 8-weeks of treatment. Monitoring subjective sleep-onset and mid-nocturnal insomnia during the course of treatment with serotonergic antidepressants may be useful for predicting acute remission of depression.

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.

Mental Health Among Medical Students During COVID-19: A Systematic Review and Meta-Analysis

Background

The mental health of medical students is an issue worthy of attention, especially during COVID-19. Many studies have shown that depression and anxiety are the main problems faced by medical students. To assess the pooled prevalence of depression and anxiety among medical students worldwide, we conducted this meta-analysis.

Methods

According to PRISMA, we used a computerized strategy to search studies in EMBASE, PubMed, PsycArticles, Web of Science, and China Biology Medicine disc. The pooled prevalence of depression and anxiety was calculated by a random-effects model. Heterogeneity was explored by subgroup analysis. Sensitivity analysis and publication bias were also carried out in this meta-analysis.

Results

Of 1316 studies, 41 studies were selected based on 36608 medical students. The pooled depression prevalence was 37.9% (95% CI: 30.7-45.4%), and pooled anxiety prevalence was 33.7% (95% CI: 26.8-41.1%). The prevalence of depression and anxiety among medical students varied by gender, country, and continent.

Conclusion

The data reported that the prevalence of depression and anxiety among medical students during COVID-19 was relatively higher than those of the general population and the healthcare workers. The impact of COVID-19 on medical students and how to protect the mental health of medical students are needed to determine through further research.
