Dose-dependent association between estimated glomerular filtration rate and the subsequent risk of depression: An analysis of a nationwide epidemiological dataset.

Although the risk of depression is well-known in the patients with kidney dysfunction, especially at the late stages, little is known about the exact point at which the decline in estimated glomerular filtration rate (eGFR) begins to significantly increase the risk of depression. In the present study, we analysed a nationwide epidemiological dataset to investigate the dose-dependent association between baseline eGFR and a future risk of developing depression in a general population. We retrospectively analysed 1,518,885 individuals (male: 46.3%) without a history of depression identified between April 2014 and November 2022 within a nationwide epidemiological database, provided by DeSC Healthcare (Tokyo, Japan). We investigated the association of eGFR with the incidence of depression using Cox regression analyses and also conducted cubic spline analysis to investigate the dose-dependent association between eGFR and depression. In the mean follow-up of 1218 ± 693 days, 45,878 cases (3.0% for total participants, 2.6% for men and 3.3% for women) of depression were recorded. The risk of depression increased with the eGFR decline as well as the presence of proteinuria. Multivariable Cox regression analysis showed the hazard ratio (95% CI) of depression in each kidney function category (eGFR ≥90, 60-89, 45-59, 30-44, 15-29, and < 15 mL/min/1.73 m2) was 1.14 (1.11-1.17), 1 (reference), 1.11 (1.08-1.14), 1.51 (1.43-1.59), 1.77 (1.57-1.99) and 1.77 (1.26-2.50), respectively. In the cubic spline analysis, the risk of depression continued to increase monotonically as the eGFR declined when the eGFR fell below approximately 65 mL/min/1.73 m2. Our analysis using a large-scale epidemiological dataset presented the dose-dependent association between eGFR decline and the risk of depression, which highlights the importance of incorporating mental health assessments into the routine care of patients with kidney dysfunction, regardless of the stage of their disease.

The efficacy and safety of remimazolam tosilate compared with propofol for endoscopic retrograde cholangiopancreatography under monitored anesthesia care: A single-center randomized controlled clinical trial

BackgroundAlthough remimazolam tosilate is an ultra-short-acting benzodiazepine that causes less respiratory and circulatory depression than propofol, studies evaluating its efficacy and safety during endoscopic retrograde cholangiopancreatography (ERCP) are limited. This study aimed to compare the efficacy and safety of remimazolam and propofol for ERCP performed under monitored anesthesia care (MAC). MethodsThis study is a randomized controlled clinical trial featuring a noninferiority design. A total of 102 eligible patients undergoing ERCP under MAC were randomly assigned to either the remimazolam tosilate group (R group) or the propofol group (P group) in a 1:1 ratio. Patients in the R group were sedated with remimazolam tosilate, while those in the P group received propofol, both under MAC. The primary efficacy endpoint was the success rate of ERCP completion under MAC. Secondary outcomes included the time to loss of consciousness, sedative effects, and perioperative adverse events at various time points for patients in both groups. ResultsBaseline characteristics of both groups were similar. The successful completion rate for ERCP under MAC was 100 % in the R group and 96.1 % in the P group, resulting in a difference of 3.92 % (95 % CI: −2%, 10 %). This difference met the pre-established criterion of being greater than −8%. The total number of norepinephrine infusions, as well as the incidence of intravenous injection pain, post-induction hypotension, post-induction bradycardia, intraoperative hypotension, respiratory depression, and hypoxemia, were significantly lower in the R group compared to the P group. Conversely, the total number of phloroglucinol uses, body movements, and instances of rapid gastrointestinal peristalsis were significantly higher in the R group than in the P group. DiscussionRemimazolam-based MAC for ERCP exhibited non-inferior efficacy compared to propofol-based MAC, while also resulting in fewer circulatory and respiratory adverse events during the procedures. Nevertheless, future studies with larger sample sizes are required to evaluate the utility of remimazolam in elderly patients.

An observational study on the modulation of anxiety, depression, and adverse event incidence in painless colonoscopy patients through venous access nursing.

To investigate the clinical significance of venous access nursing in modulating anxiety, depression, and adverse event incidence among patients undergoing painless colonoscopy. Sixty patients who underwent painless colonoscopy in our hospital from September 2021 to September 2022 were selected as the control group (CG, receiving routine perioperative nursing). Sixty patients who underwent painless colonoscopy in our hospital from October 2022 to August 2023 were taken as the study group (SG, receiving venous access nursing modulation). After nursing, patients in the SG exhibited lower scores of the Self-Rating Anxiety Scale and the Self-Rating Depression Scale than those in the CG (P < .05). The SG showed significantly lower mean Ottawa Bowel Preparation Score, but exhibited higher adequacy of bowel preparation compared with the CG (P < .05). The colonoscopy insertion time was (7.18 ± 1.02) minutes in the SG and (8.69 ± 1.00) minutes in the CG, and the colonoscopy withdrawal time was (4.66 ± 1.66) minutes in the SG and (5.64 ± 1.06) minutes in the CG, which showed statistically significant differences between the 2 groups (P < .05). The total incidence of adverse events did not have statistical significance between the 2 groups (P > .05). Application of venous access nursing in patients undergoing painless colonoscopy may help alleviate adverse emotions and shorten colonoscopy insertion time and colonoscopy withdrawal time, thus warranting recognition for its safety and efficacy.

Physical Activity as a Protective Factor Against Depression Incidence and as a Treatment for Depression

Abstract Introduction: Depression is one of the most common and serious mental health disorders that negatively affects how you feel, think, and act. This syndrome is characterized by stress and emotion dysregulation, involving compromised structural integrity of frontal-limbic networks.It causes persistent feelings of sadness and a lack of interest in activities once enjoyed. Effective treatments, including therapy and medication, are available and can help manage the symptoms and improve quality of life. The aspect of physical activity as a component of depression treatment is currently being intensively studied. Purpose of work: This work provides a review of the knowledge on the relationship between physical activity and depression. Summary: Depression has a profound impact on the personal life, relationships, and work of those affected by the condition. Pharmacological and psychological interventions remain the cornerstone of treatment. However, these treatments do not produce the desired effects in all patients. This article presents the conclusion that physical exercise, as an alternative method for preventing and treating depression, is effective. The recent literature also suggests significant mental health benefits from being physically active, even at levels below the public health recommendations. Therefore, health practitioners should encourage any increase in physical activity to enhance mental health.

Sex differences in the association between the muscle quality index and the incidence of depression: A cross-sectional study

BACKGROUND Depression presents significant challenges to mental health care. Although physical activity is highly beneficial to mental and physical health, relatively few studies have conducted on the relationship between them. AIM To investigate the association between muscle quality index (MQI) and incidence of depression. METHODS The data used in this cross-sectional study were obtained from the 2011-2014 National Health and Nutritional Examination Survey, which included information on MQI, depression, and confounding factors. Multivariable logistic regression models were employed, while taking into account the complex multi-stage sampling design. A restricted cubic spline model was utilized to investigate the non-linear relationship between the MQI and depression. Additionally, subgroup analyses were performed to identify influential factors. RESULTS The prevalence of depression in this population was 8.44%. With the adjusted model, the MQI was associated with depression in females (odds ratio = 0.68, 95% confidence interval: 0.49-0.95) but not in males (odds ratio = 1.08, 95% confidence interval: 0.77-1.52). Restricted cubic spline adjustment of all covariates showed a significant negative non-linear relationship between depression and the MQI in females. The observed trend indicated an 80% decrease in the risk of depression for each unit increase in MQI, until a value of 2.2. Subsequently, when the MQI exceeded 2.2, the prevalence of depression increased by 20% for every unit increase in the MQI. Subgroup analyses further confirmed that the MQI was negatively associated with depression. CONCLUSION The MQI was inversely correlated with depression in females but not males, suggesting that females with a higher MQI might decrease the risk of depression.

Area deprivation index, a marker of socioeconomic disadvantage, may predict severity of COVID-19 in patients and which families may experience worse symptoms of PTSD, anxiety, and depression post-ICU

BackgroundCOVID-19 disproportionately impacted marginalized populations early in the pandemic. Families of patients admitted to the intensive care unit (ICU) experienced significant psychological effects. Little is known about whether individual and patient psychological outcomes after a loved ones stay in the ICU differs by socioeconomic status, as measured by the area deprivation index (ADI).MethodsFamily members of patients with COVID-19 respiratory failure admitted to the ICU at twelve hospitals in five US states were enrolled in a larger study looking at rates of symptoms of post-traumatic stress disorder (PTSD), anxiety, and depression in the months following their loved one's ICU stay. This secondary data analysis includes eight of the twelve hospitals in four of the five states. Each participant was assigned a number indicating a level of neighborhood disadvantage based on the patient’s zip code. Patient and family level characteristics as well as symptoms of anxiety, depression, and PTSD were assessed among each neighborhood.ResultsPatients from the most disadvantaged neighborhoods had the highest proportion of patients that needed to be intubated (p = 0.005). All the patients in the most disadvantaged neighborhoods were a race other than white (p = 0.17). At 12 months post-hospitalization, there was a statistically significant difference in the proportion of family members who experienced symptoms of PTSD, anxiety, and depression between the ADI groups.ConclusionsADI may be a predictor of COVID-19 disease severity for patients on presentation to the ICU. Patients and family members experience psychological effects after a loved one’s admission to the ICU, and these outcomes vary among individuals of different socioeconomic status’, as measured by the ADI. A larger study of family members’ incidence of anxiety, depression, and post-traumatic stress disorder is needed to understand the extent to which these symptoms are impacted by neighborhood level factors as measured by the ADI.

The Association between Aortic Valve Stenosis and a Subsequent Diagnosis of Depression in Germany.

Background/Objectives: Aortic valve stenosis (AS) represents one of the most common valve diseases in the western world. It often leads to severe symptoms that can lead to a restriction of everyday life and thus to psychological stress. Therefore, we aimed to investigate the association between AS and depression in outpatients in Germany. Methods: The IQVIATM Disease Analyzer database was used to identify 14,681 individuals with non-rheumatic AS (ICD-10: I35.0 or I35.2). They were propensity score matched (1:1) based on age, sex, average yearly consultation frequency during the follow-up, and co-diagnoses to 14,681 patients without AS. Cox regression models were used to analyze the association between aortic stenosis and depression. Results: Within the follow-up period of up to 10 years, depression was diagnosed in 20.6% of AS patients compared to 20.0% in the matched cohort (p = 0.351). In the regression analysis, we were not able to discover an association between AS and a subsequent diagnosis of depression (HR: 1.03; 95% CI: 0.96-1.11). This effect was consistent among different age and sex groups. Conclusions: In the broad population of patients treated outside of hospital settings in Germany, AS was not associated with a higher incidence of depression.

Association between frequency of using ready-made meals or eating out during pregnancy and postpartum depression among community-dwelling pregnant women: a prospective cohort study.

The association between the frequency of eating ready-made meals (RMM) or eating out (EO) during pregnancy and postpartum depression remains unclear. We aimed to explore the association between the frequency of RMM or EO use during pregnancy and the incidence of postpartum depression. This study included 639 community-dwelling pregnant women who were recruited between 2019 and 2022. Data on the frequency of RMM and EO use, as well as sociodemographic, economic and lifestyle factors, were obtained using self-administered questionnaires. Data on dietary intake were obtained using a validated brief self-administered diet history questionnaire. Postpartum depression was assessed using the Japanese version of the Edinburgh Postnatal Depression Scale (EPDS). The incidence of postpartum depression (EPDS score of ≥9) based on the frequency of RMM or EO use was analysed using multiple logistic regression analysis. After adjusting for potential confounders, there was limited evidence suggesting an association between consuming RMM 3 times/week or more and the likelihood of experiencing postpartum depression, with an adjusted OR (aOR) and 95 % CI (95 % CI) of 4·16 and 1·68-10·27 (Pfor trend = 0·017) compared with consuming RMM less than 1 time/week. There was no evidence for an association between consuming EO 3 times/week or more and postpartum depression (aOR: 1·20, 95 % CI: 0·14, 10·04 and Pfor trend = 0·283). Accordingly, the present study presented weak evidence of an association between RMM and postpartum depression. Further studies with large and diverse samples are needed to overcome any potential selection bias.

The Effect of Spiritual Care Development to Reduce the Level of Depression in the Families of Intensive Care Patients

Depression is a mental condition that affects a person's physical, psychological and social functioning. Depression occurs when problems in life arise, such as feeling disappointed, lost, depression is also a form of feeling sad, which can cause unhappiness and hopelessness. This study aimed was to analyze the effect of spiritual care development to reduce the level of depression in the families of intensive care patients. This research design uses Quasy experiment pre and posttest. The population is all families of patients in the Intensive Care ward at RSUD Haji Surabaya, totaling 108 respondents. The sample size was 85 respondents who met the inclusion criteria. The independent variable from the research is spiritual care with the intervention medium being a spiritual kit and the dependent variable is the level of depression in the family who keeps the patient in the intensive care room. Data was collected using the Beck's Depression Inventory questionnaire and then analyzed using the Wilcoxon Signed rank test. The Z score value for the pre-post variable for the incidence of depression is -5.940 with a p value of Asymp. Sig. (2-tailed) of .000 &lt; 0.05, it can be seen that there is a significant influence between the results of the level of depression before and after the spiritual therapy kit. Developing spiritual care using the spiritual kit method can reduce the level of depression in the families of intensive care patients.

Depression-like behavior is associated with deficits in cognition and hippocampal neurogenesis in a subset of spinally contused male, but not female, rats

Depression and cognitive deficits present at higher rates among people with spinal cord injury (SCI) compared to the general population, yet these SCI comorbidities are poorly addressed. Sex and age appear to play roles in depression incidence, but consensus on the direction of their effects is limited. Systemic and cortical inflammation and disruptions in hippocampal neurogenesis have been identified as potential treatment targets, but a comprehensive understanding of these mechanisms remains elusive.We used a rodent SCI model to interrogate these gaps in knowledge. We examined post-injury depression-like behavior and cognitive deficits, as well as the association between affect, cognition, chronic hippocampal inflammation and hippocampal neurogenesis, in young and middle-aged male and female Sprague-Dawley rats. Depression-like behavior manifested in male and female subsets of SCI rats irrespective of age, at rates commensurate with the incidence of clinical depression. Changes in components of behavior were driven by sex and age, and affective outcomes were independent of common post-injury pathophysiological outcomes including locomotor functional deficits and spinal lesion severity. Interestingly, however, only male depression-like SCI rats exhibited deficits in hippocampal-associated spatial cognition. Neurogenesis was also disrupted in only SCI males in regions of the hippocampus responsible for affective outcomes. Decreased neurogenesis among middle-aged male subjects coincided with increases in numbers of the pro-inflammatory markers CD86 and iNOS, while middle-aged females had increased numbers of cells expressing Iba-1 and anti-inflammatory marker CD206.Overall, the present data suggest that post-SCI depression and cognition may be affected, in part, by sex- and age-dependent changes in hippocampal neurogenesis and inflammation. Hippocampal neurogenesis is a potential target to address psychological wellbeing after SCI, but therapeutic strategies must carefully consider sex and age as biological variables.

Cardiovascular health (“Life’s Essential 8”), risk of depression and anxiety: a prospective cohort study

There is a growing interest in the linkage of cardiovascular health (CVH) with depression/anxiety but the evidence of “Life’s Essential 8” CVH score is scarce. We evaluated the associations of CVH score with risk of incident depression/anxiety among ~0.4 million participants. During follow-up, 17,554 incident events with symptoms of either disorder were recorded. Per 100-point decrease in CVH score was associated with an increased risk of incident either disorder (Hazard ratio [HR] = 1.133, 95% confidence interval [CI]:1.114–1.153), depression (HR = 1.205, 95% CI:1.180–1.231), and anxiety (HR = 1.042, 95% CI:1.017–1.069). Per 100-point decrease in health assessments or health behaviors was associated with an increased risk of incident either disorder (HRhealth assessments = 1.085, 95% CI: 1.058–1.113, HRhealth behaviors = 1.217, 95% CI: 1.186–1.250). Poor CVH is a risk factor for the incident late-life depression/anxiety symptoms of middle-aged and older adults, and healthy behaviors could be targeted for the risk assessment and intervention of depression/anxiety.

The impact of solid fuel use on major depression and the buffering effect of outdoor time in the UK adults: A 12-year cohort study

BackgroundThis study aims to investigate age- and gender-specific effects of household solid fuels for heating on major depression and buffering effects of outdoor time in a high-income country. MethodsData were obtained from the UK Biobank. Participants with complete information on our studied variables and no prior diagnosis of major depression at baseline were included. Cox proportional hazards regression models were used to examine the effects of household solid fuels for heating on major depression. Subgroup analyses were conducted to investigate the buffering effects of outdoor time in summer and winter. Sensitivity analyses were performed to test the robustness of the main findings. ResultsOf 255,505 participants (50.2 % women), the 12-year cumulative incidence of major depression was 4.4 %. Household solid fuels for heating increased the risk of major depression only in women aged <45 years (HR (95%CI) = 1.30 (1.04, 1.63)). In this group, the solid fuel effect was moderated by outdoor time spending both in summer (HR (95%CI), ≤2 h/day: 1.61 (1.13, 2.28); >2 h/day: 1.13 (0.84, 1.52)) and winter (≤1 h/day: 1.35 (1.01, 1.08); >1 h/day: 1.24 (0.86, 1.77)). LimitationsSelf-reported measures might lead to recall bias and some potential confounders, such as ventilation efficiency, were not measured and controlled in data analyses. ConclusionsYounger women are more vulnerable to the impact of domestic air pollution on major depression. Promoting outdoor activities is a cost-effective and efficient approach to mitigating the risk of major depression caused by household solid fuels.

Incidence of postpartum depression among women with postpartum haemorrhage in Kano, northern Nigeria

The burden of postpartum depression (PPD), an important but largely neglected cause of maternal morbidity, is often increased by the presence of common co-morbidities, such as postpartum haemorrhage (PPH). Additionally, stress and the absence of social support can amplify PPD risk. Understanding the relationship between these conditions will help identify at-risk women and allow prompt intervention. Using a prospective cohort design, we recruited 72 women who had experienced PPH and another 72 women who had not within 24 h of delivery to assess the risk of PPD among them. The cumulative incidence of PPD among all participants was 15.3% (19/124). There was insufficient evidence to suggest that women with PPH have a higher risk of PPD than women without PPH (OR: 1.32; 95% CI: 0.55–3.13). Poor social support and high perceived stress increased the risk of PPD. We recommend screening for PPD among women with high perceived stress and low social support.

The Association Between Unplanned Pregnancy and Social Support with the Incidence of Postpartum Depression

The Association Between Unplanned Pregnancy and Social Support with the Incidence of Postpartum Depression

Observations on the efficacy of edaravone dexborneol in preventing post-stroke depression and its inflammatory mechanism: a prospective, randomized, control trial.

This study aimed to observe the effect of edaravone dexborneol (EDB) on the incidence of early post-stroke depression (PSD) and explore its inflammatory mechanisms. A prospective, randomized controlled study was conducted from January 2022 to June 2023, involving patients with acute ischemic stroke (AIS) at the Neurology Department of the Third Affiliated Hospital of Beijing University of Traditional Chinese Medicine. The control group received routine treatment, while the experimental group received routine combined EDB treatment. The main outcome measures included PSD incidence, Patient Health Questionnaire (PHQ-9) and Hamilton Depression Scale (HAMD) scores on days 14 and 30, and inflammatory factor levels on day 14. A total of 93 patients were included in the study, 51 in the experimental group and 42 in the control group. On day 14, the PSD incidence was 13.7% in the experimental group, lower than 31.0% in the control group (95%CI 0.127-0.996; p = 0.044). Compared to the control group, the experimental group showed significantly lower concentrations of pro-inflammatory cytokines IL-1β (95%CI 3.353-5.184), IL-6 (95%CI 2.694-3.426), TNF-α (95%CI 4.985-12.196), IFN-γ (95%CI 0.163-0.451), MCP-1 (95%CI 0.335-0.787), IL-17A (95%CI 0.543-1.024), and IL-23p19 (95%CI 1.677-1.959) (all p < 0.001), and higher levels of anti-inflammatory cytokines IL-4 (95%CI -1.087 to -0.941), IL-10 (95%CI -6.125 to -1.662), and IL-13 (95%CI -6.078 to -2.953) (all p ≤ 0.001). On day 30, the PSD incidence in the experimental group was 15.7%, lower than 40.5% in the control group (95%CI 0.103-0.725; p = 0.007). Compared with the control group, the experimental group had lower PHQ-9 scores on day 14 (95%CI 0.034-1.577; p = 0.041) and day 30 (95%CI 0.018-1.573; p = 0.045), and also had lower HAMD scores on day 14 (95% CI 0.281-2.856; p = 0.018) and day 30 (95% CI 0.647-3.482; p = 0.005). EDB could reduce the incidence of early PSD, reduce pro-inflammatory cytokine levels, and elevate anti-inflammatory cytokine levels, which was possibly related to the anti-inflammatory mechanism of EDB. http://www.chictr.org.cn/, identifier [ChiCTR2300067750].

Heat and Drought Have Exacerbated the Midday Depression Observed in a Subtropical Fir Forest by a Geostationary Satellite

Recently, increasing heat and drought events have threatened the resilience of Chinese fir forests. Trees primarily respond to these threats by downregulating photosynthesis including through stomatal limitation that causes a drop in productivity at noon (known as the midday depression). However, the effects of these events on midday and afternoon GPP inhibition are rarely analyzed on a fine timescale. This may result in negligence of critical responses. Here, we investigated the impact of climatic events on the midday depression of photosynthesis at a subtropical fir forest in Huitong from 2016 to 2022 using data from the Himawari 8 meteorological satellite and flux tower. Our results indicated that the highest number of midday depression occurred in 2022 (126 times) with the highest average temperature (29.1 °C). A higher incidence of midday depression occurred in summer and autumn, with 48 and 34 occurrences, respectively. Compound drought, heat, and drought events induced increases in midday depression at 74.3%, 66.0%, and 47.5%. Thus, trees are more likely to adopt midday depression as an adaptive strategy during compound drought and heat events. This study can inform forest management and lead to improvements in Earth system models.

To what extent does having diabetes influence individuals suffering from anxiety and depression?

The aim of the project is to find out to what extent diabetes affects individuals and leads to anxiety and depression, to identify the causes of diabetes and mental illnesses, and to explain how diabetes and other factors contribute to anxiety and depression as well as finding out whether diabetes is a significant cause of anxiety and depression. It will also assess and investigate the impact of diabetes on the incidence of anxiety and depression. The project is mainly focused on secondary data analysis and comparison as well as case studies. Overall, the main factors which will lead to mental disorders such as anxiety and depression are genetic factors and environmental factors, but diabetes and the use of psychoactive drugs can also increase the risk of developing mental disorders to some extent.

Parathyroidectomy and the Development of New Depression Among Adults With Primary Hyperparathyroidism

Primary hyperparathyroidism (PHPT) is a common endocrine disorder associated with neuropsychiatric symptoms. Although parathyroidectomy has been associated with improvement of preexisting depression among adults with PHPT, the effect of parathyroidectomy on the development of new depression is unknown. To determine the effect of early parathyroidectomy on the incidence of new depression among adults with PHPT compared with nonoperative management. Analyzed data included observational national Veterans Affairs data from adults with a new diagnosis of PHPT from 2000 through 2019 using target trial emulation with cloning, a biostatistical method that uses observational data to emulate a randomized clinical trial. New depression rates were compared between those treated with early parathyroidectomy vs nonoperative management using an extended Cox model with time-varying inverse probability censoring weighting, adjusted for patient demographics, comorbidities, and depression risk factors. Eligible adults with a new biochemical diagnosis of PHPT, excluding those with past depression diagnoses, residing in an assisted living/nursing facility, or with Charlson Comorbidity Index score higher than 4 were included. These data were analyzed January 4, 2023, through June 15, 2023. Early parathyroidectomy (within 1 year of PHPT diagnosis) vs nonoperative management. New depression, including among subgroups according to patient age (65 years or older; younger than 65 years) and baseline serum calcium (11.3 mg/dL or higher; less than 11.3 mg/dL). The study team identified 40 231 adults with PHPT and no history of depression of whom 35896 were male (89%) and the mean (SD) age was 67 (11.3) years. A total of 3294 patients underwent early parathyroidectomy (8.2%). The weighted cumulative incidence of depression was 11% at 5 years and 18% at 10 years among patients who underwent parathyroidectomy, compared with 9% and 18%, respectively, among nonoperative patients. Those treated with early parathyroidectomy experienced no difference in the adjusted rate of new depression compared with nonoperative management (hazard ratio, 1.05; 95% CI, 0.94-1.17). There was also no estimated effect of early parathyroidectomy on new depression in subgroup analyses based on patient age or serum calcium. In this study, there was no difference in the incidence of new depression among adults with PHPT treated with early parathyroidectomy vs nonoperative management, which is relevant to preoperative discussions about the benefits and risks of operative treatment.

The bridge relationships of PTSD and depression symptoms among snakebite victims: a cross-sectional community-based survey

BackgroundThe incidence of comorbid depression and post-traumatic stress disorder (PTSD) symptoms is higher in snakebite victims. However, the present state and contributing factors of depression and PTSD among Chinese snakebite victims remain unclear.MethodsA representative sample of 6837 snakebite victims were assessed with the Post-traumatic Stress Disorder Checklist (Civilian Version) and The Center for Epidemiologic Studies Depression Scale. Multivariate analyses, including network analysis, evaluated the contributing factors of PTSD and depression symptoms caused by snake bites, as well as the bridge symptoms of comorbidity networks.ResultsAmong 6,837 snakebite victims, 79.5% reported PTSD symptoms and 81.4% reported depression symptoms. Comorbidity of PTSD and depression symptoms was found in 75.1%. Key factors included the presence sequelae after snakebite (ORPTSD = 2.31, ORDepression = 1.89), time to medical facilities (6–8 h: ORPTSD = 3.17, ORDepression = 2.46), and marital status (divorced/widowed: ORPTSD = 1.78, ORDepression = 1.76). Symptoms I1 ("Repeated disturbing memories") and D1 ("Bothered by things that don't usually bother me") bridged PTSD and depression networks.ConclusionThe primary psychological challenges for snakebite victims in China are PTSD and depression symptoms, which is concerning. Standardized diagnosis and treatments, timely medical care, and stable marital relationships can reduce risks. Additional psychological support and management of negative memories, especially for those with severe bridge symptoms, can be beneficial. Further research should concentrate on understanding victims' psychological states and developing effective interventions.

Assessing a prediction model for depression risk using an early adolescent sample with self‐reported depression

AbstractBackgroundMajor depressive disorder (MDD) in adolescence is a risk factor for poor physical and psychiatric outcomes in adulthood, with earlier age of onset associated with poorer outcomes. Identifying Depression Early in Adolescence Risk Score (IDEA‐RS) is a model for predicting MDD in youth aged &gt;15 years, but replication in younger samples (&lt;15 years) is lacking. Here, we tested IDEA‐RS in a younger sample (9–11 years) to assess whether IDEA‐RS could be applied to earlier onset depression.MethodsWe applied IDEA‐RS predictor weights to 9854 adolescents (9–11 years) from the Adolescent Brain Cognitive Development (ABCD) Study, United States. We derived incident depression outcomes from self‐reported data at 2‐year follow‐up (11–13 years): incident MDD and increase in depression symptoms (DS). Sensitivity analyses were conducted using parent‐reported data. We assessed accuracy and calibration in predicting self‐reported incident depression and compared this to a refitted model with predictor weights derived in ABCD. Lastly, we tested associations between IDEA‐RS predictors and self‐reported incident depression.ResultsExternal replication yielded better‐than‐chance discriminative capacity for self‐reported incident depression (MDD: AUC = 61.4%, 95% CI = 53.5%–69.4%; DS: AUC = 57.9%, 95% CI = 54.6%–61.3%) but showed poor calibration with overly extreme risk estimates. Re‐estimating predictor weights improved discriminative capacity (MDD: AUC = 75.9%, 95% CI = 70.3%–81.4%; DS: AUC = 64.8%, 95% CI = 61.9%–67.7%) and calibration. IDEA‐RS predictors ‘poorest level of relationship with the primary caregiver’ (OR = 4.25, 95% CI = 1.73–10.41) and ‘high/highest levels of family conflict’ (OR = 3.36 [95% CI = 1.34–8.43] and OR = 3.76 [95% CI = 1.50–9.38], respectively) showed greatest associations with self‐reported incident MDD.ConclusionsWhile IDEA‐RS yields better‐than‐chance predictions on external replication, accuracy is improved when differences between samples, such as case‐control mix, are adjusted for. IDEA‐RS may be more suited to research settings with sufficient data for refitting. Altogether, we find that IDEA‐RS can be generalisable to early adolescents after refitting and that family dysfunction may be especially impactful for this period of development.
