Association Between Depression and Physical Conditions Requiring Hospitalization

A comparison of objective and subjective measures of physical activity, sedentary and sleep behaviors between persons with and without depressive symptoms

BACKGROUND

Major Depressive Disorder (MDD) is characterized by negative recall biases, which may impact how individuals with depressive symptoms report physical activity (PA), sedentary, and sleep behaviors. Additionally, there are discrepancies between subjective and objective behaviors in MDD. Thus, the current study investigated whether individuals with depressive symptoms differ in their subjective and objective PA, sedentary, and sleep behaviors, and whether the magnitude of these discrepancies differ from those in individuals without depressive symptoms.

METHODS

Participants from the 2011-2014 National Health and Nutrition Examination Survey (N = 8367; Ndepressed = 762) with one-week of passively-collected, wrist worn actigraphy data and self-reported questionnaires assessing PA, sedentary, and sleep behaviors were analyzed.

RESULTS

Three negative binomial models investigated the effects of group, measurement type, and their interaction on PA, sedentary, and sleep behaviors. Individuals with depressive symptoms exhibited lower PA and sleep than individuals without depressive symptoms but did not differ in sedentary behaviors. Measurement type differed across all models: self-reported PA and sleep were lower, and self-reported sedentary behaviors were greater, than objective measurements. The interaction was significant only for PA; whereas objective PA was greater than subjective measurements for all individuals, the difference was far greater for individuals with depressive symptoms.

LIMITATIONS

The absence of a clinically depressed sample and current manner of assessing subjective and objective measures may limit our generalizability and conclusions.

CONCLUSION

Our study highlights discrepancies in objective and subjective reports across domains and emphasizes the importance of incorporating objective measurements to improve psychopathology assessment.

Pathways linking BMI trajectories and mental health in an adult population-based cohort: role of emotional eating and body dissatisfaction

BACKGROUND

Overweight and obesity are associated with poor mental health, and the association is bidirectional. Few studies have examined the association between weight change and mental health over time. We aimed to provide further insight into the association between weight gain and mental health, with a focus on emotional eating and body dissatisfaction as mediating factors.

METHODS

Height and weight were self-reported upon registration, and in Spring 2022, 2023, and 2024 in the Specchio cohort (Geneva, Switzerland). BMI trajectories were estimated by (1) mixed-effects models to calculate participants' personal slopes (increase in BMI score per year), and (2) testing the odds of an upward BMI category transition from baseline to last follow-up. The associations of behavioural and psychosocial factors with BMI trajectories (slopes and transitions), and BMI trajectories with mental health outcomes were estimated using regressions adjusted for age, sex, education, and physical health condition. Structural equation modelling was used to test mediating pathways.

RESULTS

Among 7388 participants (59% women, mean age 51 years), factors associated with increasing BMI over 4 years included financial hardship, short sleep duration, less physical activity, more leisure screen time, depressive and anxiety symptoms, and emotional eating (β range [95% CI] = 0.03 [0, 0.05]-0.12 [0.09, 0.15]). Increasing BMI was associated with body dissatisfaction (β = 0.36 [0.33, 0.38]) and poorer quality of life (β = -0.06 [-0.09, -0.03]) at 4-year follow-up after adjustment for anxiety and depressive symptoms at baseline. Emotional eating partly mediated the association between anxiety and depressive symptoms at baseline and increasing BMI, and between financial hardship and increasing BMI. Body dissatisfaction and poorer self-rated health partly mediated the association between increasing BMI and quality of life at follow-up.

CONCLUSIONS

Emotional eating and body dissatisfaction contribute to the association between BMI trajectories and mental health and should be considered in weight management and mental health promotion strategies.

Comparative analysis of the risk of severe bacterial infection and septicemia in adolescents and young adults with treatment-resistant depression and treatment-responsive depression - a nationwide cohort study in Taiwan

Previous studies have shown an association between depression and increased susceptibility to infection in the general population. However, there has been no prior research specifically examining the relationship between treatment-resistant depression (TRD) and severe bacterial infections (SBI) in adolescents and young adults. This retrospective observational cohort study utilized the Taiwan National Health Insurance Research Database (NHIRD) from 2001 to 2010. It included adolescents (12-19 years of age) and young adults (20-29 years of age) diagnosed with major depressive disorder (MDD), comprising 6958 cases of TRD and 27,832 cases of antidepressant-responsive depression (ARPD). The TRD and ARPD groups were further matched (4:1) by chronological age, age at diagnosis of depression, sex, residence, and family income. The primary outcomes were severe bacterial infections (SBI) and septicemia. Cox regression analysis was conducted to identify the risk of hospitalization due to SBI or septicemia during the follow-up period. Compared with controls, the ARPD group had increased risks of SBI (hazard ratio [HR] with 95% confidence interval [CI]: 3.90, 2.73-5.57) and septicemia (HR, 95% CI: 2.56, 1.34-4.91). Notably, the risks of SBI and septicemia appeared to be further elevated in the TRD group. The TRD group exhibited higher incidences of SBI (HR, 95% CI: 6.99, 4.73-10.34) and septicemia (HR, 95% CI: 2.85, 1.28-6.36) than the control group. Adolescents and young adults with TRD had 6.99-fold and 3.90-fold increased risks of SBI and septicemia compared to individuals without MDD, respectively. Therefore, healthcare providers need to be vigilant when monitoring and implementing preventive measures in this population.

Interoception as a key node in the multidimensional psychological structural model of depression: a structural equation model analysis of integrating environmental, cognitive and behavioral-emotional factors

BACKGROUND

The psychological structural model of major depressive disorder (MDD) is complex and multifaceted, consisting of the environment factors (EF), cognitive function (CF), and behavioral-emotional manifestations (BEM). Currently, the diagnosis and treatment of MDD is difficult to improve the disease state as a whole through an intervention point. Constructing the psychological structural model of MDD and finding the critical node of the psychological structural model are meaningful for the diagnosis and treatment of MDD.

METHODS

308 MDD patients (MDDs) participated in this research. They completed assessments of 34 psychological factors, including EF, CF, BEM and interoception function (IF). Pearson correlation was used to investigate the relationship between IF and each factor in the depressive multidimensional psychological structural model (EF, CF and BEM) which was constructed by structural equation modeling (SEM). Critical nodes were identified by the goodness of fit of the model. The depressive multidimensional psychological structural model (EF, CF and BEM) was created through SEM. IF was added to the depressive multidimensional psychological structural model to further verify the pathways and effects of interoception in the network.

RESULTS

IF was significantly correlated with all psychological factors. In the depressive multidimensional psychological structural model, EF (βdirect = 0.163, p = 0.033) and BEM (βdirect = 0.230, p = 0.003) can directly influence MDD. When adding IF to the model, interoception predicted all the factors in the model. The poorer EF led to the lower IF (βdirect = - 0.346, p < 0.001). Interoception dysfunction increased the risk of the CF (βdirect = -0.525, p = 0.002) and BEM (βdirect = - 0.250, p = 0.031) of the patients. EF had the largest total effect on MDD (βdirect = 0.365, βindirect = 0.150, βtotal = 0.515), IF (βdirect = - 0.309, βindirect = - 0.126, βtotal = - 0.434) are second only to EF.

CONCLUSIONS

IF is a part of the psychological structural model of MDD that predicts EF, CF, and BEM. It could be a potential intervention point to improve the depressive state as a whole.

The Role of Acupuncture of 13 Ghost Points Combined with Cognitive Therapy in Alleviating Liver-qi Stagnation Depression: A Clinical Study

ABSTRACT

Liver-qi stagnation-type depression, marked by irritability and emotional imbalance, often responds inadequately to medication alone. This study explored the efficacy of combining acupuncture at the 13 ghost points with cognitive therapy for this condition. Conducted at our hospital from January 2022 to January 2023, the study involved 76 patients with liver-qi stagnation-type depression, divided into an observation group (acupuncture + cognitive therapy) and a control group (fluoxetine tablets), with 38 patients in each group. We assessed clinical efficacy, Hamilton Depression Scale (HAMD) scores, Self-Rating Depression Scale (SDS) scores, Traditional Chinese Medicine (TCM) syndrome scores, liver-qi stagnation syndrome main symptom scores, and serum levels of 5-hydroxytryptamine (HT), vasoactive intestinal peptide (VIP), and cAMP response element-binding protein (CREB) before and after treatment. The observation group achieved a total effective rate of 81.58%, significantly higher than the control group ( P < 0.05). Both groups showed significant reductions in HAMD and SDS scores, TCM syndrome scores, and liver-qi stagnation syndrome principal symptom scores posttreatment, with the observation group demonstrating superior improvements ( P < 0.05). Serum levels of 5-HT, VIP, and CREB also increased significantly in both groups, with greater changes in the observation group ( P < 0.05). The results suggest that the combination of acupuncture and cognitive therapy is more effective than fluoxetine alone in treating liver-qi stagnation-type depression, improving both clinical symptoms and physiological indicators.

Unveiling the brain mechanism underlying depression: 12 Years of insights from bibliometric and visualization analysis

Depression is a common but serious mental health illness affected human's physiology and psychology. In contemporary times, neurophysiological research on depression has emerged as a prominent area of investigation, yet there remains a paucity of review elucidating the central mechanisms of depression in the brain. Consequently, we undertook a bibliometric analysis and visualization assessment to underscore recent advancements in research pertaining to the neural underpinnings of depression. By employing these methods, we have collected articles spanning the period from 2013 to 2024, shedding light on the latest insights into the brain mechanisms associated with depression. Bibliometric analysis found 16327 research papers in the field of brain mechanism underlying depression, overall showing a sustained growth trend. Through meticulous analysis of collected data on institutions and countries, authors, co-cited literature, keywords, etc., this paper humbly aims to tentatively identify future research hotspots and frontiers, hoping to modestly contribute to and stimulate further scholarly progress in the field.

Association of Depression With Handgrip Strength and Muscle Mass in Young and Middle-Aged American Adults From NHANES 2011-2014: A Cross-Sectional Study

PURPOSE

To investigate relationship between depression and handgrip strength (HGS) and appendicular lean mass (ALM) in Young and middle-aged adults.

DESIGN

Cross-sectional study.

SETTING

Data from participants aged 20-59 from the 2011-2014 National Health and Nutrition Examination Survey.

SAMPLE

In a study of 4927 middle-aged Americans, 2564 (52.30%) were men and 2363 (47.7%) were women, with an average age of 38.57 ± 11.72. Among this group, 716 individuals (14.53%) experienced mild depression, while 385 individuals (7.81%) suffered from moderate to severe depression.

MEASURES

Data of HGS and ALM were collected by handgrip test, and whole-body dual-energy X-ray absorptiometry scans. Depression was assessed using the Patient Health Questionnaire-9. Linear and logistic regression, restricted cubic spline regression analyses and subgroup analysis were conducted to evaluate the association.

RESULTS

Following multivariate logistic regression analysis, the study showed that a 1-point increase in the depression score was associated with a 4% increase in the probability of reduced grip strength for both males (95% CI: 1.01-1.07) and females (95% CI: 1.01-1.06). Additionally, for males, there was a 5% increase in the likelihood of decreased muscle mass (95% CI: 1.01-1.09), whereas the decline in muscle mass for females did not exhibit statistical significance. Subgroup analysis indicated that the inverse relationship between depression and grip strength, along with the negative association between depression and muscle mass among males, remained consistent in the 40-59 age range.

CONCLUSION

This research revealed an inverse relationship between depression and grip strength in middle-aged and young individuals, and a negative association between depression and ALM was only noted in males. Early intervention could be beneficial from age 40.

Depression and Its Effect on Geriatric Rehabilitation Outcomes in Switzerland's Aging Population

Background and Objectives: Depression is a common mental problem in the older population and has a significant impact on recovery and general well-being. A comprehensive understanding of the prevalence of depressive symptoms and their effects on functional outcomes is essential for improving care strategies. The primary aim of this study was to determine the prevalence of depressive symptoms in older patients undergoing geriatric rehabilitation and to assess their specific impact on their functional abilities. Materials and Methods: A retrospective study was conducted at the Lucerne Cantonal Hospital in Wolhusen, Switzerland, spanning from 2015 to 2020 and including 1159 individuals aged 65 years and older. The presence of depressive symptoms was assessed using the Geriatric Depression Scale (GDS) Short Form, while functional abilities were evaluated using the Functional Independence Measure (FIM) and the Tinetti test. Data analysis was performed using TIBCO Statistica 13.3, with statistical significance set at p < 0.05. Results: Of the participants, 22.9% (N = 266) exhibited depressive symptoms, with no notable differences between genders. Although all patients showed functional improvements, the duration of rehabilitation was prolonged by two days (p = 0.012, d = 0.34) in those with depressive symptoms. Alarmingly, 76% of participants were classified as at risk of falling based on the Tinetti score. However, no significant correlation was found between the GDS and Tinetti scores at admission (p = 0.835, r = 0.211) or discharge (p = 0.336, r = 0.184). The results from the non-parametric Wilcoxon matched-pairs test provide compelling evidence of significant changes in FIM scores when comparing admission scores to those at discharge across all FIM categories. Conclusions: Depressive symptoms are particularly common in geriatric rehabilitation patients, leading to prolonged recovery time and increased healthcare costs. While depressive symptoms showed no correlation with mobility impairments, improvements in functional status were directly associated with reduced GDS scores. Considering mental health during admission and planning is critical in optimizing rehabilitation outcomes.

Relationship between social activities and cognitive impairment in Chinese older adults: the mediating effect of depressive symptoms

Background

The differential impacts of various social activities on dementia prevention and the mediating role of depression in this relationship remain unclear.

Objectives

This study aimed to identify the effects of different social activities on cognitive function, examine the mediating role of depression, and provide evidence for targeted interventions to prevent cognitive decline.

Methods

Using data from CHARLS, we employed RCS analysis and Structural Equation Modeling to examine the relationships between social activities, depression, and cognitive function in older adults.

Results

Social activity participation is non-linearly inversely related to both cognitive impairment and depression risk. Cognitive function and social activities were significantly mediated by depression. Cognitively stimulating and physically stimulating activities had the greatest positive effects on mental health.

Conclusion

Our findings highlight the complex interplay between social engagement, depression, and cognitive health in aging. They support developing targeted interventions promoting physical and cognitive social activities to maintain cognitive function and reduce depression risk in older adults, potentially alleviating the burden of cognitive impairment in aging populations.

Short-Term Outcomes and Multidimensional Factors Associated With Preoperative Sedentary Behavior Among Chinese Older Adults With Gastric Cancer: An Observational Study

PURPOSE

The current study aimed to examine the short-term outcomes and multidimensional factors associated with preoperative sedentary behavior among Chinese older adults with gastric cancer.

METHOD

An observational study was conducted among older adults with gastric cancer in a tertiary hospital in Jiangsu, China. A total of 393 participants were enrolled by convenience sampling. Sedentary behavior was assessed using the International Physical Activity Questionnaire-Short Form (IPAQ-SF). Logistic regression was applied to explore the relationship between preoperative sedentary behavior and short-term outcomes. Univariate and multivariate analyses were used to determine the factors associated with participants' sedentary behavior.

RESULTS

Preoperative sedentary behavior was related to multiple outcomes, including total complications, prolonged length of stay, and increased hospitalization costs. Two or more comorbidities and depression were risk factors for sedentary behavior. High-density lipoprotein; female sex; and high school, middle school, and primary school and below educational levels were protective factors for sedentary behavior.

CONCLUSION

Health care professionals need to simultaneously concentrate on multidimensional aspects linked to sedentary behavior to successfully administer behavioral interventions for enhancing older adults' overall prognosis. [Journal of Gerontological Nursing, 51(1), 32-41.].

Association between depression symptom severity and total cost of care: Findings from a large, 2-year, claims-based, retrospective population health study

BACKGROUND

Despite the substantial impact of depression on individuals and healthcare utilization, little is known about the specific relationship between depression severity and total cost of care (TCC). This study evaluates the association between depression symptom severity and TCC and how changes in severity affect TCC.

METHODS

The analysis was conducted using insurance claims data and data from electronic health records between January 1, 2019 and December 31, 2020. Inclusion criteria comprised insured individuals with coverage during 2019 or 2020, aged one year or older, and identified as having depression in at least one year of the study. Depression symptom severity was assessed using the screening Identification and Stratification (IDS) framework and data available to the research team. The main outcome was TCC per member per month (PMPM) evaluated across the two-year period.

RESULTS

Across 2019 and 2020, 744,854 members met inclusion criteria. A total of 369,460 members were studied across both years. Greater depression symptom severity was associated with higher TCC across both years. Unchanged severity was associated with limited change in TCC from 2019 to 2020. Decrease in depression symptoms was associated with an average $41 reduction in PMPM spend, whereas increase in depression symptom severity was associated with an average $608 increase.

LIMITATIONS

Limitations include fragmented data, retrospective design that limits causality, and the IDS framework design.

CONCLUSION

Changes in depression symptom severity were significantly associated with changes in TCC. Findings reveal financial and clinical opportunities associated with early identification and targeted management of depression.

Application of "Internet +" continuous emotion management training in patients with depression

Objective

Explore the application effects of "Internet +" continuous emotional management training in depression patients and analyze the feasibility of innovative rehabilitation training methods.

Methods

Conveniently selected 100 discharged patients meeting the diagnostic criteria for depression from the Second Affiliated Hospital of Xinxiang Medical University between August 2022 and January 2023 as study subjects. They were divided into an intervention group and a control group according to their discharge time, with 50 patients in each group. The control group received routine monthly telephone follow-ups and "Internet +" health popularization. The intervention group received "Internet +" continuous emotional management training in addition to the control group's protocol. Before and after the intervention, the Hamilton Depression Rating Scale (HAMD), the Chinese version of the Cognitive Emotion Regulation Questionnaire (CERQ-C), and the Social Adaptation Function Evaluation Scale (SAFE) were used to compare the differences in depression relief, cognitive emotion regulation levels, and social functions between the two groups.

Results

Two patients in the control group and three patients in the intervention group were lost to follow-up during the intervention, Ultimately, 48 patients in the control group and 47 patients in the intervention group completed the study. Before the intervention, there were no statistically significant differences between the two groups in HAMD scores, CERQ-C subscale scores, and SAFE scores (P < 0.05). After the intervention, the intervention group had significantly lower HAMD and SAFE scores compared to the control group (P < 0.05). In the CERQ-C questionnaire, the intervention group scored lower in self-blame, rumination, catastrophizing, and blaming others but higher in acceptance, positive refocusing, refocusing on planning, positive reappraisal, and putting into perspective compared to the control group, with statistically significant differences (P < 0.05).

Conclusion

"Internet +" continuity emotion management training can reduce the severity of depression in post-discharge patients and enhance their emotional management and social adaptability. This approach is feasible in clinical practice.

Poor perceived oral health is associated with adverse mental health outcomes among Syrian refugees in Canada

While inadequate oral health has been linked to adverse mental health outcomes, there is limited understanding of such implications among refugees who bear a disproportionate burden of oral health disparities. This study aims to examine the effect of self-rated oral health on depression, anxiety, and stress among Syrian refugee parents resettled in Ontario. In this cross-sectional study, a total of 540 Syrian refugee parents who resided in Ontario for an average of 4 years and had at least one child under 18 years old were interviewed between March 2021 and March 2022. Information about self-rated oral health was gathered based on the question "In general, how would you rate the health of your teeth and mouth". Responses ranged from 1 representing "excellent" and 5 representing "very poor". The mean score (SD) of self-rated oral health was 3.2 (1.2). Mental health outcomes of depression, anxiety, and stress were measured using the Depression Anxiety Stress Scales (DASS-21). Multiple linear regression analyses were performed to assess the independent relationship between self-rated oral health and depression, anxiety, and stress, adjusting for other variables including, sociodemographic-, migration-, and health-related factors. Among participants, 6.3% rated their oral health as excellent, 26.9% as good, 23.1% as fair, 24.8% as poor, and 18.7% as very poor. Results of the multiple linear regression analyses indicated that poorer self-rated oral health was significantly associated with higher levels of depression (Adjβ = 0.98; p = 0.002; 95% CI = 0.38-1.59), anxiety (Adjβ = 1.03; p< 0.001; 95% CI = 0.54-1.52), and stress (Adjβ = 1.25; p< 0.001; 95% CI = 0.61-1.88). Further efforts and targeted interventions are needed to address the unmet oral health needs of Syrian refugees to improve mental health outcomes within this vulnerable population.

Observational and genetic evidence disagree on the association between loneliness and risk of multiple diseases

Loneliness-the subjective experience of social disconnection-is now widely regarded as a health risk factor. However, whether the associations between loneliness and multiple diseases are consistent with causal effects remains largely unexplored. Here we combined behavioural, genetic and hospitalization data from the UK Biobank to examine the associations of loneliness with a wide range of non-overlapping diseases. During a median 12.2-year follow-up, loneliness was associated with greater risks in 13 of 14 disease categories and 30 of 56 individual diseases considered. Of the 30 diseases significantly associated with loneliness, 26 had genetic data available for Mendelian randomization (MR) analyses. After Benjamini‒Hochberg correction and multiple sensitivity analyses within the MR framework, non-causal associations were identified between genetic liability to loneliness and 20 out of the 26 specific diseases, including cardiovascular diseases, type 2 diabetes mellitus, obesity, chronic liver diseases, chronic kidney disease, most neurological diseases and the other common diseases. Genetic liability to loneliness was only potentially causally associated with the remaining six diseases. Socioeconomic factors, health behaviours, baseline depressive symptoms and comorbidities largely explained the associations between loneliness and diseases. Overall, our study revealed a dissociation between observational and genetic evidence regarding the associations of loneliness with multiple diseases. These findings suggest that loneliness may serve as a potential surrogate marker rather than a causal risk factor for most diseases tested here.

Depressive and Anxiety Symptoms in Community-Dwelling Women in Rural Areas of Greece in the Post-COVID-19 Pandemic Era

Background/Objectives: Depressive and anxiety syndromes are associated with elevated disability and are more prevalent in women. Data on the prevalence of depressive and anxiety disorders in the rural context are limited and contradictory. It is relevant to study common mental disorders in rural areas in the most vulnerable population of women, particularly in the post-COVID-19 pandemic era. Methods: This is a cross-sectional study that was conducted in two primary healthcare sites in the rural region of Farsala, Central Greece after the obviation of all restrictive measures that had been posed due to the COVID-19 pandemic. All consecutive female patients that attended the study sites for any non-emergent reason were asked to participate in the study. For the recording of symptoms of depression and anxiety, the self-reported Depression, Anxiety, Stress Scale-21 (DASS-21) was used. Results: The study sample consisted of 129 women. The majority of participants were >50 years, with 27.9% being older adults. A small percentage (13.2%) suffered a chronic physical disease. A large proportion of the sample, slightly exceeding 40%, reported clinically relevant symptoms of anxiety, whereas a lower percentage of women with depressive symptoms was detected (17.1%). Symptoms of anxiety and depression were found to be interrelated, while a number of sociodemographic variables were associated with both, such as older age, education (primary), living status (alone, OR 123.5; 95% CI: 7.3-2098.8 for anxiety; OR 3.5; 95% CI: 1.3-9.8 for depression), employment (not working, (OR 0.157; 95% CI: 0.06-0.41 for anxiety; OR 0.08; 95% CI: 0.01-0.62 for depression) and the history of a chronic disease (OR 33.8; 95% CI: 4.3-264.7 for anxiety; OR 37.2; 95% CI: 10-138.1 for depression). Self-rated financial status was not related to symptoms of anxiety or depression. Conclusions: The study highlights the importance of inquiring for symptoms of depression and anxiety in women attending the rural primary care setting. The use of valid and reliable self-reported instruments that are easy to administrate may be helpful in this regard.

The cumulative impact of trauma, chronic illness, and COVID-19 stress on mental health in a case-control study of adults with psychotic disorders in Ethiopia

BACKGROUND

The COVID-19 pandemic has profoundly impacted the economic, psychological, and social well-being of people in Ethiopia. Pandemic-related fears can exacerbate anxiety and depression symptoms among those with pre-existing physical and mental health conditions as well as those with prior exposure to traumatic events.

METHODS

We used data from the Ethiopia NeuroGAP-Psychosis study (898 cases and 941 controls with and without a diagnosis of psychosis respectively, 66% male, mean age = 37 years). Data was collected between November 2021 and June 2022 during the COVID-19 pandemic from four hospitals in Ethiopia (three in Addis Ababa and one in Jimma city). Structural equation modeling analysis was conducted to examine the associations between trauma exposure, physical health conditions (like arthristis, neurological disorders, diabetes), COVID-19 stress, and psychological distress (depression and anxiety symptoms). We assessed direct and indirect effects for mediation, and conducted multigroup analysis to examine moderation by case control status.

RESULTS

We found evidence that the impact of greater trauma exposure and physical health conditions on higher psychological distress was mediated through higher COVID-19 stress. Sociodemographic characteristics (older age and being maried) were associated with higher psychological distress, with these associations mediated through greater trauma, physical health conditions, and COVID-19 stress. Case-control status also moderated the associations between these variables, with the mediation effects being stronger in cases and weaker in controls. Further, cases reported greater trauma and psychological distress, while controls reported more physical health conditions and COVID-19 stress.

IMPLICATIONS

Our findings uniquely assess the interaction of health and emergency related factors in understudied settings like Ethiopia. They underscore the importance of including daily hardships and environmental stressors, along with prior trauma exposure, as risk factors for the assessment of mental health symptoms. This study has key implications for mental health screening and intervention research in response to complex emergency contexts like Ethiopia with a history of armed conflict in addition to the COVID-19 pandemic. Our findings can aid the development of targeted services that address the mental health of at-risk groups with pre-existing mental and physical health conditions.

Association of periodontitis with all-cause and cause-specific mortality among individuals with depression: a population-based study

To detect the association between periodontitis and all-cause as well as cause-specific mortality rates among adults diagnosed with depression. Participants diagnosed with depression were selected from NHANES across three periods (1988-1994; 1999-2004; 2009-2014). Cox proportional hazards and Weibull accelerated failure time (AFT) models were utilized to calculate hazard ratios (HRs), time ratios (TRs), and their 95% confidence intervals (CIs) to evaluate the association between moderate-to-severe periodontitis and all-cause as well as cause-specific mortality among participants with depression. white blood counts and C-reactive protein were used to assess the mediating role of systemic inflammation. Among the 1,189 participants with a median follow-up of 9.25 years, 133 deaths were recorded. After adjusting for multiple variables, moderate-to-severe periodontitis was obvious associated with an increased risk of cancer-related mortality in individuals with depression (Cox: HR 3.22, 95% CI 1.51-6.83, P = 0.002; AFT: TR 0.70, 95% CI 0.52-0.94, P = 0.017). Neither WBC nor CRP significantly mediate the association between periodontitis and cancer-related mortality. The risk of cancer-related mortality rose with the severity of periodontitis (P for trend = 0.021). However, no association was observed between moderate-to-severe periodontitis and other kinds of mortality. Moderate-to-severe periodontitis is linked to an elevated risk of cancer-related mortality among adults diagnosed with depression, with the mortality risk increasing alongside the severity of periodontitis. No significant mediating effect of systemic inflammation was found in this association. These findings highlight the importance of addressing periodontal health in individuals with depression. By uncovering the association between periodontitis and mortality in this population, our study underscores the potential benefits of preventive dental care and periodontal treatment in reducing the risk of cancer-related mortality in individuals with depression.

Analysis of risk factors for postoperative anxiety and depression in endometriosis patients with reproductive intention

BACKGROUND

The occurrence of postoperative depression and anxiety in patients with endometriosis (EMS) not only causes psychological distress, but may also harm their physical health.

AIM

To explore the postoperative depression status, and its influencing factors, of EMS patients with reproductive intention.

METHODS

A total of 321 EMS patients with reproductive intent were included. Using the self-rating anxiety scale and self-rating depression scale, EMS patients with anxiety or depression were distinguished. A clinical model for predicting anxiety or depression in EMS patients was constructed and evaluated using a nomogram, receiver operating characteristic curve, and calibration curve.

RESULTS

The results of the single factor analysis showed that smoking, coffee, EMS stage, chronic pelvic pain, and sexual discomfort may be related to anxiety. Further, smoking, drinking, spouse, annual household income and EMS stage may be related to depression in EMS patients. Multivariate logistic regression illustrated that smoking, coffee, chronic pelvic pain and sexual discomfort may be independent risk factors for anxiety in EMS patients, while smoking, EMS stage (Phase III and Phase IV), spouse and high annual household income may be independent risk factors for depression in EMS patients. Additionally, the models used to predict the risk of anxiety or depression in EMS patients have good predictive value.

CONCLUSION

The anxiety and depression of EMS patients may be related to many factors. In clinical treatment, additional attention should be paid to the psychological status of EMS patients.

Bidirectional Associations Between Cardiometabolic Multimorbidity and Depression and Mediation of Lifestyles: A Multicohort Study

Background

Cardiometabolic multimorbidity (CMM) and depression are major health concerns, and the onset of either condition may heighten the risk of developing the other.

Objectives

The goal of this study was to characterize the reciprocal associations between CMM and depression among middle-aged and older adults.

Methods

This multicohort study used harmonized data from 5 prospective cohorts from China, South Korea, the United States, the United Kingdom, and Europe. Cardiometabolic diseases (CMDs) (including diabetes, heart diseases, and stroke) and depression were assessed at baseline and at 7 to 8 years' follow-up. Lifestyle factors, including physical activity, alcohol consumption, and smoking status, were regarded as potential mediators. Two sets of analyses, CMM-depression analyses (n = 67,188) and depression-CMM analyses (n = 65,738), were conducted to explore the bidirectional associations between CMM and depression.

Results

In the CMM-depression analyses, 16,596 (24.7%) individuals developed depression. Participants with a single CMD (HR: 1.24; 95% CI:1.19-1.29) and CMM (HR: 1.52; 95% CI: 1.42-1.63) at baseline had higher risks of depression occurring. Physical activity and alcohol consumption significantly mediated 7.5% and 6.9% of the CMM-depression association, respectively. In the depression-CMM analyses, 1,461 (2.2%) participants developed CMM. The HR for developing CMM was 1.31 (95% CI: 1.14-1.50) in patients with depression, with increased risk of developing more CMDs. Physical activity and alcohol consumption mediated 12.0% and 7.1% of the depression-CMM association. The bidirectional relationships were more pronounced in Western countries than in Asian countries.

Conclusions

CMM and depression were bidirectionally associated. The mediated effects of lifestyle factors were larger in the depression-lifestyle-CMM pathway than in the CMM-lifestyle-depression pathway.

Hospital Length of Stay and Associated Factors in Adult Patients with Depression in Germany: A Cross-Sectional Study

Objective: The aim of the present study was to evaluate the hospital length of stay (LoS) and its associated factors among adult patients hospitalized with depression in Germany. Methods: This cross-sectional study included all adults (≥18 years) hospitalized with depression from January 2019 to December 2023 treated in 36 hospitals across Germany. The primary outcome was patients' hospital LoS in days. The associations between age, sex, depression severity, co-diagnoses, hospital, and hospital LoS were analyzed using hierarchical multivariable linear regression models. Results: A total of 6579 patients (mean age 46.6 ± 17.7 years) with 8965 hospitalizations for depression were available. The mean hospital LoS was 35.2 days. Severe depression (+4.9 days) was associated with a longer hospital LoS, with moderate depression as the reference. Older age was positively associated with a longer hospital LoS. Vitamin D deficiency (+9 days), lipid metabolism disorders (+8 days), obesity (+8 days), sleep disorders (+7 days), and reaction to severe stress and adjustment disorders (+5 days) were also significantly associated with hospital LoS. Conclusions: In patients with depression, higher depression severity, advanced age, vitamin D deficiency, lipid metabolism disorders, obesity, sleep disorders, reactions to severe stress, and adjustment disorders were associated with a longer hospital LoS. Addressing these factors through comprehensive and integrated care strategies could help optimize hospitalization duration and improve overall patient outcomes.

The relationship between depression and lipid accumulation product: a population-based study

Background

Lipid Accumulation Product (LAP) is a new type of obesity index. The relationship between LAP and depression is unclear, and this cross-sectional study was conducted to explore the relationship between LAP and depression using the National Health and Nutrition Examination Survey (NHANES) database from 2005-2018.

Methods

In our study, logistic regression analysis was used to calculate the odds ratio between depression and LAP, and subgroup analysis and sensitivity analysis were also performed to verify the robustness of the results.

Results

The analysis included 13,240 participants aged 20 years or older. After adjusting for multiple variables, LAP was positively associated with depression, OR 1. 50 (95% CI, 1. 05-2. 12). In subgroup analysis, LAP was significantly positively, associated with depression among male (2. 52, OR; 95% CI, 1. 39,4. 57), non-Hispanic Black (2. 55, OR; 95% CI, 1. 49,4. 36), those without diabetes (1. 67, OR; 95% CI, (1. 06,2. 61) or in the overweight (2. 09, OR; 95% CI, (1. 23,3. 54) subgroups. After inverse probability of treatment weighting (IPTW), the OR for the highest versus lowest quartile was 1. 55 (95% CI: 1. 24 - 1. 95).

Conclusion

There are positive results between LAP and depression after adjusting for multiple potential variables, and prospective studies are needed to verify the results.

Waning waves of mood: The declining trend of hospitalized patients with affective disorders in Germany

INTRODUCTION

Affective disorders profoundly affect individuals' emotional well-being and quality of life. This study investigates the epidemiology of affective disorders in Germany from 2011 to 2021, focusing on incidence rates, age- and sex-standardized rates, and developmental trends.

METHODS

Using nationwide data of ICD-10 diagnosis codes from 2011 to 2021, this cross-sectional study analyzed inpatient cases of affective disorders in individuals aged 20 years or older. Age- and sex-standardized incidence rates were calculated based on the population size of each birth cohort in the 16 German federal states. Incidence rate ratios (IRRs) for 2011 to 2021 and 2019 to 2021 were compared with a two-sample z-test.

RESULTS

Between 2011 and 2021, F30 (manic episode) showed a decline of 42.8 % to an incidence of 4.9 per 100,000 inhabitants, even though not statistically significant (p = 0.322). F31 (bipolar affective disorder) remained relatively stable with a reduction of 15.3 % to an incidence of 13.6 per 100,000 inhabitants in 2021 (p = 0.653). F32 (depressive episode) decreased statistically significant by 25.7 % to an incidence of 64.1 per 100,000 inhabitants (p = 0.072). F33 (recurrent depressive disorder) slightly increased by 18.3 % to an incidence of 94.6 per 100,000 inhabitants (p = 0.267). No statistically significant differences were found when comparing the COVID-19 pandemic year 2021 to 2019 incidences (p ≥ 0.529).

CONCLUSION

The study provides valuable insights into the changing landscape of affective disorders in Germany over the past decade. The observed decline in incidence rates underscores the importance of continued efforts to promote mental health awareness and access to care.

Pathology of pain and its implications for therapeutic interventions

Pain is estimated to affect more than 20% of the global population, imposing incalculable health and economic burdens. Effective pain management is crucial for individuals suffering from pain. However, the current methods for pain assessment and treatment fall short of clinical needs. Benefiting from advances in neuroscience and biotechnology, the neuronal circuits and molecular mechanisms critically involved in pain modulation have been elucidated. These research achievements have incited progress in identifying new diagnostic and therapeutic targets. In this review, we first introduce fundamental knowledge about pain, setting the stage for the subsequent contents. The review next delves into the molecular mechanisms underlying pain disorders, including gene mutation, epigenetic modification, posttranslational modification, inflammasome, signaling pathways and microbiota. To better present a comprehensive view of pain research, two prominent issues, sexual dimorphism and pain comorbidities, are discussed in detail based on current findings. The status quo of pain evaluation and manipulation is summarized. A series of improved and innovative pain management strategies, such as gene therapy, monoclonal antibody, brain-computer interface and microbial intervention, are making strides towards clinical application. We highlight existing limitations and future directions for enhancing the quality of preclinical and clinical research. Efforts to decipher the complexities of pain pathology will be instrumental in translating scientific discoveries into clinical practice, thereby improving pain management from bench to bedside.

The brain structure, inflammatory, and genetic mechanisms mediate the association between physical frailty and depression

Cross-sectional studies have demonstrated strong associations between physical frailty and depression. However, the evidence from prospective studies is limited. Here, we analyze data of 352,277 participants from UK Biobank with 12.25-year follow-up. Compared with non-frail individuals, pre-frail and frail individuals have increased risk for incident depression independent of many putative confounds. Altogether, pre-frail and frail individuals account for 20.58% and 13.16% of depression cases by population attributable fraction analyses. Higher risks are observed in males and individuals younger than 65 years than their counterparts. Mendelian randomization analyses support a potential causal effect of frailty on depression. Associations are also observed between inflammatory markers, brain volumes, and incident depression. Moreover, these regional brain volumes and three inflammatory markers-C-reactive protein, neutrophils, and leukocytes-significantly mediate associations between frailty and depression. Given the scarcity of curative treatment for depression and the high disease burden, identifying potential modifiable risk factors of depression, such as frailty, is needed.

The relationship between the meaning of life, psychological well-being, self-care, and social capital, with depression and death anxiety in the elderly living in nursing homes: The mediating role of loneliness

The current study aims to investigate the meaning of life, psychological well-being, self-care, and social capital, with depression and death anxiety in the elderly living in nursing homes through the mediating role of loneliness. The statistical population included all the elderly aged at least 60 years living in Tehran, Qazvin and Zanjan, Iran in 2020, among whom 489 (273 men and 216 women) were selected using convenience sampling method. Participants filled out Steger's Meaning of Life, Ryff and Singer's Psychological Well-Being Scale, Söderhamn et al.'s Self-Care Ability, Nahapiet and Ghoshal's Social capital, Beck's depression, Templer's Death Anxiety, Russell et al.'s Loneliness questionnaires. The results indicated that meaning of life, psychological well-being, self-care, and social capital are negatively associated with loneliness, which in turn, is positively associated to depression. Furthermore, meaning of life, psychological well-being, self-care, and social capital are negatively associated with loneliness, which in turn, is positively associated to death anxiety. Moreover, the results of path analysis revealed that the hypothesized model of the current study has an excellent fit in the study sample. That is, meaning of life, psychological well-being, self-care, and social capital are related to depression and death anxiety through mediating role of loneliness.

Impact of physical and sexual abuse on risk of hospitalisations for physical and mental illnesses: insights from two large prospective cohort studies

Background

Physical abuse can lead to severe health consequences that extend beyond immediate harm. We explored the associations of physical abuse experienced during childhood and adulthood with a wide range of adult health conditions requiring hospital treatment.

Methods

We utilised data from a sub-cohort of 157,366 UK Biobank participants (46.4% of the baseline population; age range 45-81; 89,101 women) and repeated analyses in an independent population of 85,929 adults from the Finnish Public Sector (FPS) study (age range 17-78; 68,544 women). Participants in both cohorts reported instances of physical and sexual abuse at study baseline. Follow-up included 77 common health conditions ascertained from linkage data to national hospital and mortality registries.

Findings

Mean follow-up duration was 4.6 years (SD 0.14) in UK Biobank and 10.6 years (4.3) in FPS. Physical and sexual abuse was associated with 22 mental and physical health conditions. After multivariable adjustments, participants who experienced abuse during both early and later stages of life had a 2.12- (95% confidence interval 1.39-3.23) to 3.37-fold (1.52-7.45) increased risk of mental and behavioural disorders, a 1.46 (1.20-1.79) to 1.83 (1.05-3.20) times increased risk of metabolic, haematologic, and respiratory diseases, and a 1.24 (1.07-1.45) times higher risk of inflammatory diseases compared with non-exposed participants. The absolute risk difference between these groups was greatest for metabolic and haematologic conditions (rate 381 and risk difference 160 per 100,000 person-years). Frailty, comorbidities, and competing risk of death did not modify these associations, but the possibility of bias or residual confounding cannot be excluded.

Interpretation

Repeated exposure to physical and sexual abuse amplifies the risk of hospitalisations from mental disorders and physical diseases spanning diverse organ systems. Addressing this issue may necessitate multifaceted strategies, including shifts in societal norms, legal measures, and increased healthcare provision for affected individuals and their families.

Variability in the prevalence of depression among adults with chronic pain: UK Biobank analysis through clinical prediction models

BACKGROUND

The prevalence of depression among people with chronic pain remains unclear due to the heterogeneity of study samples and definitions of depression. We aimed to identify sources of variation in the prevalence of depression among people with chronic pain and generate clinical prediction models to estimate the probability of depression among individuals with chronic pain.

METHODS

Participants were from the UK Biobank. The primary outcome was a "lifetime" history of depression. The model's performance was evaluated using discrimination (optimism-corrected C statistic) and calibration (calibration plot).

RESULTS

Analyses included 24,405 patients with chronic pain (mean age 64.1 years). Among participants with chronic widespread pain, the prevalence of having a "lifetime" history of depression was 45.7% and varied (25.0-66.7%) depending on patient characteristics. The final clinical prediction model (optimism-corrected C statistic: 0.66; good calibration on the calibration plot) included age, BMI, smoking status, physical activity, socioeconomic status, gender, history of asthma, history of heart failure, and history of peripheral artery disease. Among participants with chronic regional pain, the prevalence of having a "lifetime" history of depression was 30.2% and varied (21.4-70.6%) depending on patient characteristics. The final clinical prediction model (optimism-corrected C statistic: 0.65; good calibration on the calibration plot) included age, gender, nature of pain, smoking status, regular opioid use, history of asthma, pain location that bothers you most, and BMI.

CONCLUSIONS

There was substantial variability in the prevalence of depression among patients with chronic pain. Clinically relevant factors were selected to develop prediction models. Clinicians can use these models to assess patients' treatment needs. These predictors are convenient to collect during daily practice, making it easy for busy clinicians to use them.

Temporal and bidirectional association of depression and physical illnesses: Analyzing the pooled data from independently conducted cross-sectional national surveys at three distinct time points

OBJECTIVE

Depression is a widespread mental health issue, often coexisting with physical conditions. Understanding its interplay with physical illnesses is crucial for holistic care.

METHODS

We analyzed the pooled data from three cross-sectional surveys of the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 2016, 2018, and 2020. Data on depression and physical illness for participants aged 19 and above were collected based on information provided by the participants.

RESULTS

In cases where depression and physical illnesses occur independently, the diagnosed age for depression is typically earlier than that of physical health conditions. Furthermore, when exploring scenarios where depression coexists with physical illnesses, it is observed that depression often precedes the development of these conditions in most cases. However, exceptions to this trend are found in diabetes mellitus, thyroid disorders, and asthma, where the presence of these diseases is linked to an elevated risk of depression onset. Interestingly, the study also implies that the mood state associated with depression, rather than the diagnosis itself, may influence health-related behaviors, potentially playing a role in the development of physical illnesses.

CONCLUSION

Depression and physical illnesses share complex associations. Early detection, interventions, and addressing lifestyle factors are vital. This study's insights underscore the need for comprehensive mental and physical health care, though further research is needed for deeper understanding. The findings emphasize the importance of considering depression as a potential risk factor for physical illnesses and highlight the interplay between depression and physical health.

Serum Acetylcarnitine as a Diagnostic Marker in Depression Episodes

Background:

Depression is a serious public health concern due to its prevalence and associated discomfort, dysfunction, morbidity, and economic impact. Depression is more prevalent in women than in males. There is a need to investigate the course of depressive disorders in India to identify the necessity and duration of ongoing treatment. Studies should also assess cost-effective treatment strategies that can be easily implemented in primary care settings to successfully treat depression.

Methods:

This study aimed to estimate the Serum L-Acetyl Carnitine (LAC) levels in depressive episodes, mainly to find a correlation between the levels and depression and also to correlate the values to the severity of depression with a depression rating scale like Montgomery–Åsberg Depression Rating Scale (MADRS). LAC levels were estimated using an enzyme-linked immunosorbent assay kit.

Results:

A cross-sectional study was conducted with 60 individuals after obtaining their informed consent. This included 30 cases of diagnosed depression and 30 age and sex-matched normal controls. The diagnosed depressive episodes were rated in MADRS, and a score was assigned based on the same. The results were tabulated and statistically analyzed. The mean age of the case group was 41.37 ± 11.32 and control group was 41.50 ± 14.37. The incidence of depressive symptoms was higher in females (53%) than males (47%). The incidence of depressive symptoms was higher in the 41–50-year age group than in any other group. The acetyl carnitine-LAC levels were significantly decreased in patients with depressive episodes (950.7 ± 902.7) compared to the control (1799.6 ± 67.1), respectively. The Pearson’s correlation shows there is a strong negative correlation between the MADRS score and the levels of acetylcarnitine in the cases which was statistically significant,P< 0.001.

Conclusions:

LAC may have an important role in the pathophysiology of depression by its epigenetic action on metabotropic glutamate receptors and the decrease in the brain tissue may induce depressive symptoms, and consequently, their supplementation causes a rapid antidepressant effect. Hence, it could be a useful biochemical marker for the diagnosis of depression and also an effective for the treatment of depression.

Risks of undernutrition and depression in hospitalized patients: A cross-sectional study

Undernutrition in hospitalized patients is a significant healthcare burden worldwide. Depression is a major global health problem characterized by symptoms such as altered mood, loss of interest and pleasure, and impairment in cognitive and physical functions. Patients hospitalized for medical conditions have a higher risk of depression than the general population. The purpose of this study was to explore the relationship between undernutrition risk and depression risk in hospitalized patients. The design of this study was an observational cross-sectional analytic. A questionnaire form created by the investigator including sociodemographic data, dietary patterns, presence of chronic diseases and anthropometric measurements, Nutritional Risk Screening and Patient Health Questionnaire-2 were applied to the patients. All quantitative data were expressed as the median and interquartile range and qualitative data were expressed as numbers and percentage. Mann-Whitney U test and Kruskal-Wallis test were used to analyze nonparametric data; Chi-square and Fisher Exact test were used to analyze qualitative data. P < .05 was considered statistically significant. A total of 308 patients who met the criteria were reached. Undernutrition was detected in 28.6% of the participants, and depression was present in 37.3%. A statistically significant relationship was found between the risk of undernutrition and the risk of depression, with individuals without a risk of depression being found to have a lower risk of undernutrition. (P < .001). The risk of undernutrition was found to increase with advancing age. Moreover, individuals with higher values for arm muscle area, arm muscle circumference, mid-upper arm circumference, triceps skinfold thickness, calf circumference, and body mass index had a lower risk of undernutrition. No relationship was found between gender and the risk of depression. However, a statistically significant relationship was observed between age and the risk of depression, indicating that older patients had a higher risk of depression. In this study, a statistically significant relationship was found between the risk of undernutrition and the risk of depression in hospitalized patients. It was observed that the risk of undernutrition was lower in individuals without risk of depression.

Dissecting Relations between Depression Severity, Antidepressant Use, and Metabolic Syndrome Components in the NHANES 2005-2020

We aimed to dissect the complex relations between depressive symptoms, antidepressant use, and constituent metabolic syndrome (MetS) components in a representative U.S. population sample. A total of 15,315 eligible participants were included from 2005 to March 2020. MetS components were defined as hypertension, elevated triglycerides, reduced high-density lipoprotein cholesterol, central obesity, and elevated blood glucose. Depressive symptoms were classified as mild, moderate, or severe. Logistic regression was used to evaluate the relationship between depression severity, antidepressant use, individual MetS components and their degree of clustering. Severe depression was associated with the number of MetS components in a graded fashion. ORs for severe depression ranged from 2.08 [95%CI, 1.29-3.37] to 3.35 [95%CI, 1.57-7.14] for one to five clustered components. Moderate depression was associated with hypertension, central obesity, raised triglyceride, and elevated blood glucose (OR = 1.37 [95%CI, 1.09-1.72], 1.82 [95%CI, 1.21-2.74], 1.63 [95%CI, 1.25-2.14], and 1.37 [95%CI, 1.05-1.79], respectively). Antidepressant use was associated with hypertension (OR = 1.40, 95%CI [1.14-1.72]), raised triglyceride (OR = 1.43, 95%CI [1.17-1.74]), and the presence of five MetS components (OR = 1.74, 95%CI [1.13-2.68]) after adjusting for depressive symptoms. The depression severity and antidepressant use were associated with individual MetS components and their graded clustering. Metabolic abnormalities in patients with depression need to be recognized and treated.
