Distinct Facial Processing Related Negative Cognitive Bias in First-Episode and Recurrent Major Depression: Evidence from the N170 ERP Component

BackgroundStates of depression are associated with increased sensitivity to negative events. For this novel study, we have assessed the relationship between the number of depressive episodes and the dysfunctional processing of emotional facial expressions.Conclusion/SignificanceThese results provide new evidence that having more recurrent depressive episodes and serious depressive states are likely to aggravate the already abnormal processing of emotional facial expressions in patients with depression. Moreover, it further suggests that the impaired processing as indexed by N170 amplitude for positive face identification may be a potentially useful biomarker for predicting propagation of depression while N170 amplitude for negative face identification could be a potential biomarker for depression recurrence.     

Community survey of factors associated with consultation for low back pain

ObjectiveTo investigate the psychosocial factors associated with consultation for low back pain.DesignTwo phase cross sectional postal survey.SettingBradford Metropolitan Health District.Subjects1813 adults responding to the phase 1 questionnaire. 540 of the 782 with an episode of low back pain in the past 12 months completed the second questionnaire.Results406 (52%) of the respondents reporting back pain in the past 12 months had not consulted a health professional. Logistic regression showed that consultation was associated with externalised beliefs regarding pain management (odds ratio 3.6; 95% confidence interval 2.1 to 6.0). Duration of pain affected the factors associated with consultation. Consultation for episodes lasting less than two weeks (n=290) was associated with greater than median pain (3.0; 1.7 to 5.5), consultation for episodes over two weeks (n=243) was associated with increased disability (3.7; 1.5 to 9.0), and consultation for episodes over three months (n=143) with increased depression (3.9; 1.3 to 11.8).ConclusionsThe results support a role for psychosocial factors in consultation for low back pain and suggest that the reasons for consultation vary with duration of pain. Duration of the episode may be a useful guide to management of non-specific low back pain.

Key messages

• Only half of those who experience low back pain consult a health service professional
• Most of those who consult have had low back pain for more than two weeks
• The severity of pain may influence consulting behaviour at the acute stage, but after the acute period those who consult are more likely to have increased disability, externalised beliefs about pain management, and depressive symptoms.
• Management of low back pain may need to vary according to the duration of pain

     

Social rhythm regularity moderates the relationship between sleep disruption and depressive symptoms in veterans with post-traumatic stress disorder and major depressive disorder

ABSTRACT

Approximately 50% to 80% of individuals with posttraumatic stress disorder (PTSD) also meet criteria for major depressive disorder (MDD). Sleep disturbance is a major concern in both PTSD and MDD, and is associated with poor treatment response, poor functional outcome and increased suicide risk. Social rhythm regularity, or the consistency of daily habitual behaviors, is theoretically linked to circadian rhythms and may be disturbed in both PTSD and MDD. The present study examined the relationship between social rhythm regularity, sleep disruption and MDD and PTSD symptoms in a sample of veterans with comorbid PTSD and MDD. Baseline data were obtained from 56 male veterans who met DSM-IV criteria for PTSD and MDD. Veterans completed the Social Rhythm Metric (SRM), a self-report questionnaire that assesses the regularity of routines by determining how regularly individuals completed 17 different types of activities. In a linear regression model, increased minutes awake after sleep onset (WASO) was a significant predictor of increased depression scores on the Hamilton Rating Scale for Depression (p < .05). SRM scores did not significantly predict depressive symptoms, however the interaction of WASO and SRM significantly predicted depressive symptoms (p = <.05), with significant relationships found at SRM scores less than 3.62. Neither minutes awake after sleep onset, SRM scores, nor their interaction was associated with PTSD symptom severity. Social and possibly circadian rhythm regularity may represent a risk or resilience factor for individuals with comorbid PTSD and MDD. Findings highlight the importance of exploring the interactions of sleep and social/circadian rhythms in depression in order to inform continued treatment development.     

Resiliencia en las personas mayores durante la primera ola pandémica de la COVID-19 en Chile: una perspectiva desde los determinantes sociales de la salud

ObjectiveTo assess the association between social determinants of health (SDH) and resilience in older people during the first period of confinement in the COVID-19 pandemic in Chile.Materials and methodsAn observational study with a cross-sectional design was conducted using a nationally representative survey data-set. In this survey, using a systematic randomization process, a subsample of people aged ≥60 years from the community were interviewed by telephone during the first wave of the COVID-19 pandemic in Chile. Resilience was assessed using the Brief Resilient Coping Scale (BRCS) and depressive symptoms using the Patient Health Questionnaire (PHQ-9) scale. The SDH considered were: age, sex, educational level, employment status, social isolation, loneliness, discontent with housing and health care needs.ResultsA total sample of 582 persons was obtained. The mean age was 71 years (SD: 7.64; 69% women). A significant association was obtained between low resilience and the following conditions: loneliness (OR: 1.776 [95% CI: 1.146–2.751]), high risk of social isolation (OR: 1.667 [95% CI: 1.149-2.419]), and depressive symptoms (OR: 2.602 [95% CI: 1.795-3.774]). Female gender was a protective factor (OR: 0.589 [95% CI: 0.406-0.855]).ConclusionThe SDH, such as loneliness and social isolation, are factors associated with low resilience in older people during the COVID-19 pandemic and may be taken into account in planning public health intervention strategies.     

Psychological Resilience after Hurricane Sandy: The Influence of Individual- and Community-Level Factors on Mental Health after a Large-Scale Natural Disaster

Several individual-level factors are known to promote psychological resilience in the aftermath of disasters. Far less is known about the role of community-level factors in shaping postdisaster mental health. The purpose of this study was to explore the influence of both individual- and community-level factors on resilience after Hurricane Sandy. A representative sample of household residents (N = 418) from 293 New York City census tracts that were most heavily affected by the storm completed telephone interviews approximately 13–16 months postdisaster. Multilevel multivariable models explored the independent and interactive contributions of individual- and community-level factors to posttraumatic stress and depression symptoms. At the individual-level, having experienced or witnessed any lifetime traumatic event was significantly associated with higher depression and posttraumatic stress, whereas demographic characteristics (e.g., older age, non-Hispanic Black race) and more disaster-related stressors were significantly associated with higher posttraumatic stress only. At the community-level, living in an area with higher social capital was significantly associated with higher posttraumatic stress. Additionally, higher community economic development was associated with lower risk of depression only among participants who did not experience any disaster-related stressors. These results provide evidence that individual- and community-level resources and exposure operate in tandem to shape postdisaster resilience.     

Resiliencia en cuidadores de personas con demencia: estudio preliminar

Introduction

Caring for a relative with dementia often has negative effects on the caregive?s physical and psychological health. However, many caregivers successfully cope with the stress factors arising from care, and even have uplifts during their experience, showing high resilience levels. This study presents a preliminary analysis of resilience in caregivers of patients with dementia, exploring its relationship with different variables.

Material and methods

Resilience was assessed (by CD-RISC) in 53 family caregivers of patients with dementia. Resilience was correlated to the following variables: caregiving context, stressors (e.g., cognitive impairment), appraisals (e.g., burden), moderators (e.g., personality traits and resources), and caregiving consequences (physical and psychological health).

Results

The participants showed moderate scores on resilience. Resilience was associated with poor emotional and physical status (significant inverse correlations with anxiety, depression, psycho-active drug use, health habits…). High resilience scores were significantly correlated to burden, neuroticism and extraversion, self-efficacy, self-esteem and less use of emotion focused coping strategies.

Conclusions

Higher resilience relates to a good emotional and physical status in caregivers. Moreover, resilience is more associated with caregiver variables (e.g., appraisal and coping with care, personality features), than to situational variables. The data highlight the strengthening of these types of appraisal and coping as a way to improve caregivers’ resilience and, consequently, their health.

Prevalence of Undiagnosed Depression among Persons with Hypertension and Associated Risk Factors: A Cross-Sectional Study in Urban Nepal

BackgroundDespite an increasing number of studies exploring prevalence of depression among hypertensive patients in high income countries, limited data is available from low and middle income countries, particularly Nepal. Our aim was to investigate the prevalence of undiagnosed (sub clinical) depression and associated risk factors among hypertensive patients attending a tertiary health care clinic in Nepal.MethodsThe study was based on a cross-sectional study design, with 321 hypertensive patients attending the Out-Patient Department of a central hospital in Nepal. Blood measure was recorded via a mercury column sphygmomanometer. Depression levels were assessed using the Beck Depression Inventory-Ia (BDI) scale. Demographics and risk factors were assessed.ResultThe proportion of participants with undiagnosed depression was 15%. Multivariable analyses demonstrated an increase in BDI scores with increased aging. Approximately a 1 point increase in the BDI score was observed for each additional decade of aging in hypertensive patients. Additional factors associated with increased risk of depression included being female (4.28 point BDI score increase), smoking (5.61 point BDI score increase), being hypertensive with no hypertensive medication (4.46 point BDI score increase) and being illiterate (4.46 point BDI score increase).ConclusionsAmong persons with hypertension in outpatient settings in Nepal, demographic (age, sex, education), behavioural (smoking,) and adherence factors (anti-hypertensive medication) were associated with undiagnosed depression. Screening programs in Nepal may assist early intervention in hypertensive patients with sub clinical depression.     

Current depression among adult cancer survivors: Findings from the 2010 Behavioral Risk Factor Surveillance System

BackgroundA cancer diagnosis and subsequent treatments constitute a significantly increased psychological burden among cancer patients. This study examined the prevalence of current depression and the risk factors associated with a high burden of depression among cancer survivors in the US.MethodsWe analyzed data from 3550 cancer survivors (aged ≥18 years) and 26,917 adults without cancer who participated in the 2010 Behavioral Risk Factor Surveillance System. Depressive symptoms were assessed by the Patient Health Questionnaire-8 diagnostic algorithm. Participants with a total depression severity score of ≥10 were defined as having current depression. Prevalence and prevalence ratios were estimated by conducting log-linear regression analysis while controlling for potential confounders.ResultsOverall, 13.7% of cancer survivors (vs. 8.9% of adults without cancer, P < 0.001) reported having current depression; the prevalence varied significantly by cancer category. Among cancer survivors, after multivariate adjustment for covariates, cancer diagnosis within a year, being in ‘other’ racial/ethnic group, divorced, separated, widowed, or never married, current or former smoker, or having histories of diabetes, disability, or depression were associated with significantly higher prevalence ratios for current depression; whereas being at an advanced age (≥60 years old), attaining educational levels of >high school graduate, or engaging in leisure-time physical activity were associated with significantly lower prevalence ratios for current depression.ConclusionOur results indicate that cancer survivors are at increased risk of current depression. Targeting cancer survivors at high risk of depressive issues may be especially important for clinical support and interventions aimed at improving mental well-being.     

Las ganas de vivir como expresión del bienestar de las personas mayores

IntroductionWill-to-live, a central concept in well-being theories, represents a positive attitudinal component towards one's own life. It has been identified as a mediator between the self-perception of aging and longevity and health. The objective of this study is to characterise elderly people with high levels of will-to-live in the main dimensions of positive psychology.MethodThe study included the voluntary participation of 165 adults, aged between 54-89 years, users of senior centres in the Community of Madrid. Will-to-live and other dimensions of well-being and health were evaluated. The correlations between the different evaluated dimensions were analysed, and comparisons made in terms of different levels of will-to-live, as well as an analysis of the dimensions that contribute most to the will-to-live.ResultsCorrelations among the majority of variables were statistically significant, with a decrease in the coefficients being observed when controlling the effect of the will-to-live. When groups with different levels of will-to-live are compared with well-being and health, there are statistically significant differences in practically all of the dimensions. Gratitude, positive affect, and depression are the dimensions that best predict will-to-live.ConclusionOlder adults that make up the group with high will-to-live are characterised by higher levels of optimism, gratitude, positive affect, sense of life, psychological prosperity, resilience, happiness, and satisfaction with life, as well as lower levels of depression and negative self-perception of aging. The implications of these results point towards the relevance of will-to-live in successful aging.     

Burden of depression and anxiety among leprosy affected and associated factors—A cross sectional study from India

BackgroundLeprosy is a Neglected Tropical Diseases (NTDs) known to cause stigma and discrimination in low-and middle-income countries. It often results in visible impairments, thus pre-disposing to poor mental health. Aim of the study was to estimate the prevalence of depression and anxiety among people affected by Leprosy and to determine the associated factors.Methodology/Principal findingsA multi-centric, cross-sectional study was carried out in four leprosy endemic states of India—Chhattisgarh, Maharashtra, West Bengal and Tamil Nadu in randomly selected blocks (a sub-unit of district), from one district in each state. From selected blocks those registered for leprosy treatment at public health or referral centres, people above the age of 18 years were interviewed with PHQ-9 and GAD-7 questionnaires for Depression and Anxiety, respectively. Disease profile like leprosy classification, deformity grade, number and site of the patches and socio-economic status were collected along with individual data.Of the total 220 respondents, prevalence of depression and anxiety symptoms was, 33% (73) and 19% (42), respectively. Presence of disability (47%) and Female gender (46%) were significantly associated with depression. Presence of disability (32%), Lower income group (27%) and low education (22%) were significantly associated with symptoms of anxiety. As the severity of disability increased, risk of developing depression and anxiety increased.ConclusionThe study indicates that more than 30% of people affected by leprosy have mental health problems, which emphasizes the importance of mental health care services in leprosy. Women, those who had lower level of education, those belonging to lower socio-economic status and those with any level of disability due to leprosy are at risk of developing depression and/or anxiety. The study concludes more attention to be paid to the categories identified to be at risk.

Interactions between Handler Well-Being and Canine Health and Behavior in Search and Rescue Teams

ABSTRACT

This study reports on three years of prospective, longitudinal data on the psychological well-being of the human handlers and the health and behavior of the search and rescue dogs deployed in New York City and Washington, DC in the aftermath of the terrorist attacks on September 11, 2001. Eighty-five human handlers (63 deployed and 22 controls) and ninetyfour dogs (66 deployed, 28 controls) were assessed at multiple time points including 6 months, 1 year, 2 years, and 3 years after the 9/11 attacks. Humans were assessed for psychological health by structured clinical interview and self-report. Dogs were assessed for physical health and behavior by veterinary records and handler report. For humans, deployment after 9/11 did indeed represent a relatively short-term risk factor for developing symptoms of depression and posttraumatic stress disorder (PTSD). By and large, however, the sample showed remarkable resilience as a whole, and overall rates of DSM-IV diagnoses were quite low. By year 3, 9/11 deployment no longer conferred any special risk. On the other hand, long-term employment in an emergency profession did emerge as a significant risk factor for symptoms of PTSD by year 3. With respect to the interaction between handler emotional well-being and canine health and behavior, we found that physical illness and/or death in the dog was prospectively associated with greater symptoms of depression in the handler. We also found that symptoms of depression and PTSD in the handlers prospectively predicted behavioral problems in the dogs over time. Separation anxiety, attachment/attention seeking, chasing, and excitability emerged in the dogs at 1 year. Behavioral problems escalated to aggression towards other dogs at year 2 and separation anxiety, aggression towards other dogs, and aggression towards strangers at year 3. Like any relationship, the partnership between a handler and his or her working dog can confer both protection—when the relationship is going well and both members are healthy—and vulnerability—when either member is physically ill or psychologically or behaviorally distressed.     

Circadian Variation of Myocardial Ischemia in Patients with Stable Coronary Artery Disease

The circadian variation of myocardial ischemia detected during 24-h ambulatory electrocardiographic monitoring (AEM) was analyzed in 123 patients with stable angina pectoris, positive exercise test, and angiographically proven coronary artery disease. A total of 437 ischemic episodes (ST-segment depression ≥ 1 mm and duration ≥ 1 min) were observed; 333 (76%) episodes remained asymptomatic, and only 104 (24%) episodes were accompanied by anginal pain. Ischemic episodes predominantly occurred during the morning hours, between 6 a.m. and noon, and another smaller peak was observed in the afternoon, between 4 and 5 p.m.; this diurnal pattern was influenced neither by the extent of coronary artery disease nor the degree of left ventricular dysfunction. The circadian variation was restricted to the 345 (78%) ischemic episodes preceded by increases in heart rate; the 92 (22%) episodes without prior heart rate changes occurred randomly throughout the day. The morning peak in ischemic episodes was not associated with less myocardial oxygen supply; in contrast, heart rate profile showed parallel increases during the morning and afternoon hours, indicating elevated myocardial demand during these periods. Ischemia-related ventricular arrhythmias were concentrated during the morning hours, but their overall prevalence was low–28 (6%) of 437 ischemic episodes. These findings may provide further insight into the pathomechanisms of acute clinical events in patients with coronary artery disease, since the circadian variation of myocardial ischemia is very similar to that observed for the onset of myocardial infarction and sudden cardiac death.     

Factors associated with self-rated health status of older people with multimorbidity in Colombia: A cross-sectional study

Background and objectiveIn Colombia, older adults (60 years and older) are expected to represent 15.5% of the overall population by 2025. Consequently, the demand for social and healthcare services will increase, especially because of the numerous medical conditions associated with aging. The purpose of the present study was to determine the patient's self-rated health status of older adults with multimorbidity and its determining factors based on gender in an insurance company of the Colombian health system.MethodologyA cross-sectional study was performed to analyze the sociodemographic and clinical characteristics of 438 patients older than 75 years as well as their self-rated health status (EQ-5D-3L questionnaire) during the first geriatric consultation of a comprehensive healthcare program. A multivariate linear regression analysis was performed to identify factors determining their self-rated health status.ResultsWomen had a worse self-rated health status than men [mean (standard deviation) EQ-5D index score: 0.77 (0.20) vs. 0.65 (0.18); p < 0.001]. In all sample, factors independently associated with self-rated health status were self-perception of weakness and dependency. In men, additional factors related to EQ-5D index were low levels of physical activity, recurrent falls, fecal incontinence, and auditory and visual disorders. In women, other health-determining factors were decrease in walking speed, and a medical history of depression/anxiety.ConclusionsFactors associated with the self-rated health status of older adults who were part of a comprehensive healthcare program in Colombia varied according to gender. This study will help in approaching health interventions in healthcare programs for older adults in a differentiated manner.     

Young Women With Major Depression Live on Higher Homeostatic Sleep Pressure Than Healthy Controls

There is mounting evidence for the involvement of the sleep-wake cycle and the circadian system in the pathogenesis of major depression. However, only a few studies so far focused on sleep and circadian rhythms under controlled experimental conditions. Thus, it remains unclear whether homeostatic sleep pressure or circadian rhythms, or both, are altered in depression. Here, the authors aimed at quantifying homeostatic and circadian sleep-wake regulatory mechanisms in young women suffering from major depressive disorder and healthy controls during a multiple nap paradigm under constant routine conditions. After an 8-h baseline night, 9 depressed women, 8 healthy young women, and 8 healthy older women underwent a 40-h multiple nap protocol (10 short sleep-wake cycles) followed by an 8-h recovery night. Polysomnographic recordings were done continuously, and subjective sleepiness was assessed. In order to measure circadian output, salivary melatonin samples were collected during scheduled wakefulness, and the circadian modulation of sleep spindles was analyzed with reference to the timing of melatonin secretion. Sleep parameters as well as non-rapid eye movement (NREM) sleep electroencephalographic (EEG) spectra were determined for collapsed left, central, and right frontal, central, parietal, and occipital derivations for the night and nap-sleep episodes in the frequency range .75–25?Hz. Young depressed women showed higher frontal EEG delta activity, as a marker of homeostatic sleep pressure, compared to healthy young and older women across both night sleep episodes together with significantly higher subjective sleepiness. Higher delta sleep EEG activity in the naps during the biological day were observed in young depressed women along with reduced nighttime melatonin secretion as compared to healthy young volunteers. The circadian modulation of sleep spindles between the biological night and day was virtually absent in healthy older women and partially impaired in young depressed women. These data provide strong evidence for higher homeostatic sleep pressure in young moderately depressed women, along with some indications for impairment of the strength of the endogenous circadian output signal involved in sleep-wake regulation. This finding may have important repercussions on the treatment of the illness as such that a selective suppression of EEG slow-wave activity could promote acute mood improvement.

Association of Childhood Physical and Sexual Abuse with Intimate Partner Violence,Poor General Health and Depressive Symptoms among Pregnant Women

ObjectiveWe examined associations of childhood physical and sexual abuse with risk of intimate partner violence (IPV). We also evaluated the extent to which childhood abuse was associated with self-reported general health status and symptoms of antepartum depression in a cohort of pregnant Peruvian women.MethodsIn-person interviews were conducted to collect information regarding history of childhood abuse and IPV from 1,521 women during early pregnancy. Antepartum depressive symptomatology was evaluated using the Patient Health Questionnaire-9. Multivariable logistic regression procedures were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (95%CI).ResultsAny childhood abuse was associated with 2.2-fold increased odds of lifetime IPV (95%CI: 1.72–2.83). Compared with women who reported no childhood abuse, those who reported both, childhood physical and sexual abuse had a 7.14-fold lifetime risk of physical and sexual IPV (95%CI: 4.15–12.26). The odds of experiencing physical and sexual abuse by an intimate partner in the past year was 3.33-fold higher among women with a history of childhood physical and sexual abuse as compared to women who were not abused as children (95%CI 1.60–6.89). Childhood abuse was associated with higher odds of self-reported poor health status during early pregnancy (aOR = 1.32, 95%CI: 1.04–1.68) and with symptoms of antepartum depression (aOR = 2.07, 95%CI: 1.58–2.71).ConclusionThese data indicate that childhood sexual and physical abuse is associated with IPV, poor general health and depressive symptoms in early pregnancy. The high prevalence of childhood trauma and its enduring effects of on women’s health warrant concerted global health efforts in preventing violence.
