RESUMO

Victims of traumatic events that involve repeated interpersonal aggression and low or no chance of escape frequently report intense Self-Conscious Emotions (SCEs), such as Shame, Guilt, and Humiliation. Humiliation is the reaction to a forced loss of status and is hypothesized to have unique contributions to the development and maintenance of Posttraumatic Stress Disorder (PTSD) and Complex Posttraumatic Stress Disorder (CPTSD). However, previous studies did not include humiliation or did not simultaneously probe the relative contribution of each SCE to posttraumatic symptoms. This study aimed to investigate the dynamics between specific SCEs and trauma-related symptomatology in the general population who suffered a form of complex trauma. Four hundred forty-nine people (77.11% women) exposed to domestic violence and sexual abuse answered an online survey. We investigated whether each emotion would accurately predict probable PTSD and CPTSD levels above the proposed cutoff. We estimated a network model to understand the dynamics of their interactions and whether the traumatic event type would moderate relationships between SCEs and posttraumatic stress symptoms, comparing networks of two types of complex trauma. No SCE predicted PTSD, but humiliation was a predictor of CPTSD while controlling for Shame and Guilt. Humiliation was also the most central SCE domain in the networks of both traumatic events. Our results stress the relevance of Humiliation to understanding posttraumatic stress symptoms and the necessity to consider humiliation when studying the emotional processing in complex trauma.

RESUMO

Cumulative trauma is usually devastating and can lead to severe psychological consequences, including posttraumatic stress disorder (PTSD). Exposure to various types of traumas, particularly during childhood, can be even more deleterious than the sheer number of events experienced. This epidemiological study is the first to investigate the impact of discrete childhood traumatic exposure on the risk of developing lifetime PTSD in a representative sample of the general population of the two biggest Brazilian cities. Participants were aged between 15 and 75 years old, living in São Paulo and Rio de Janeiro, Brazil, who had experienced traumatic events (N = 3,231). The PTSD diagnosis was assessed using the DSM-IV criteria through the version 2.1 of Composite International Diagnostic Interview. To operationalize childhood cumulative trauma, we considered the sum of 15 different childhood trauma categories that occurred before PTSD onset. The final multivariate logistic regression model indicated a strong relationship between the number of discrete types of childhood traumas and the likelihood of the lifetime PTSD development. The lifetime PTSD risk increased 28 % with each different type of childhood trauma when adjusted by confounds. Our study strengthens the evidence associating childhood cumulative trauma to increased lifetime PTSD risk.

RESUMO

Internet-delivered cognitive-behavioral therapy (I-CBT) is effective in treating post-traumatic stress disorder (PTSD) symptoms, offering enhanced accessibility and cost-effectiveness. However, it's important to note that these technologies may not be suitable for all age groups. Therefore, we conducted a systematic review and meta-analysis to determine if the effectiveness of I-CBT in treating PTSD varies based on the patients' mean age. We conducted a systematic review of the literature, focusing on randomized controlled trials (RCTs) in the ISI Web of Science, PubMed/MEDLINE, and PsycINFO databases. Following this, we performed a meta-analysis and evaluated the risk of bias using the Cochrane risk of bias quality assessment tool. In this study, we examined patient-related factors (civil or military status, age, and gender), clinical characteristics (baseline PTSD severity and type of trauma), and treatment characteristics (type of intervention, synchronous or asynchronous delivery, and the number of sessions) as independent variables. The dependent variable was the reduction in mean PTSD symptoms. Five RCTs out of 1,552 screened studies were included in this review, all of which showed some level of concern regarding potential bias. Our meta-analysis indicates that I-CBT is equally effective regardless of patients' mean age. Since all RCTs included only provide the mean age of the patients, further randomized controlled trials should address the effectiveness of I-CBT among different age groups.

Objetivo: Describir los resultados del estudio y las investigaciones concluidas en ambos programas de formación académica. Método: Se realizó un estudio descriptivo de corte transversal basado en el análisis de los 69 proyectos de investigación desarrollados. Para la descripción de los resultados se realizó el análisis de contenido del 20 por ciento de las investigaciones. Resultados: El 63,8 `por ciento de los estudios fueron investigaciones biomédicas, y el 36,1 por ciento fueron estudios psicosociales. En ambos casos, el contexto social en las comunidades fue de (84,7 por ciento). Entre las investigaciones médicas predominaron las dirigidas al paciente con hipertensión arterial (39,1 por ciento) centradas en la adherencia terapéutica (32,6 por ciento). En los estudios psicológicos predominaron los dirigidos a niños y adolescentes (23,0 por ciento) y a profesionales sanitarios (23,0 por ciento) centradas en las afecciones mentales (19,2 por ciento). Conclusiones: Los proyectos desarrollados concluyeron resultados satisfactorios, se describió con mayor sistematicidad el enfoque comunitario en las investigaciones biomédicas. Se abordaron contenidos relativos a la adherencia terapéutica y las afectaciones a la salud mental. El impacto de la COVID-19 fue valorado como generador de dificultades en niños y adolescentes, profesionales sanitarios y en la población(AU)


Introduction: In 2020 and 2021, the Department of Research on Addiction of Havana University of Medical Sciences participated as teachers, advisors and thesis directors in two academic training programs for Ecuadorian students: specialization in Family and Community Medicine and master's degree in Clinical Psychology with a mention in Community Mental Health. Objective: To describe the results of the study and the research concluded in both academic training programs. Methods: A descriptive cross-sectional study was carried out based on the analysis of the sixty nine research projects established. The content analysis of 20 percent of the investigations was carried out to describe the results. Results: 63.8percent of the studies were biomedical research and 36.1 percent were psychosocial studies. In both cases, communities was the social context (84.7percent). Among the medical investigations, those aimed at the patient with hypertension (39.1percent) focused on therapeutic adherence (32.6percent) predominated. In the psychological studies, those intended at children and adolescents (23.0percent) and health professionals (23.0percent) focused on mental disorders (19.2percent) prevailed. Conclusions: These projects yielded satisfactory results. The community approach in biomedical research was more systematically described. Contents related to therapeutic adherence and the effects on mental health were addressed. The impact of COVID-19 was assessed as generator of difficulties in children and adolescents, health professionals, and in the population(AU)

RESUMO

OBJECTIVES: The most recent DSM-5 (2013) and ICD-11 (2018) diagnostic criteria for posttraumatic stress disorder (PTSD) encompass 20 and six symptoms, respectively, organized in different structures. This study aimed to investigate the dimensions of the Posttraumatic Stress Disorder Checklist 5 (PCL-5) according to the DSM-5's broader definition of PTSD and the ICD-11's narrower approach, as well as to explore an alternative restricted model that retains the core symptoms explicitly related to traumatic experiences. METHODS: Data were gathered from Brazilian employees (n=1,101) who had directly experienced traumatic life events or had been exposed to them because of their work activities. Confirmatory factor analysis (CFA) and exploratory structural equation modeling (ESEM) were used to evaluate the configural and metric structures of the models. RESULTS: We estimated seven models of the latent structure of PTSD including the four-factor DSM-5 and three-factor ICD-11 PTSD models. Given the lack of evidence of their validity, an alternative 10-symptom model was tested. The final seven-item PTSD model considerably improved estimation of the PTSD construct. This solution showed reliable items with non-redundant content, acceptable fit indices, and satisfactory configural and metric properties. CONCLUSION: The more parsimonious one-dimensional model comprising the core PTSD symptoms has the potential to improve assessment of PTSD.

RESUMO

In 2018, Complex Post Traumatic Stress Disorder (CPTSD) was officially recognized as a distinct syndrome in the International Classification of Diseases, 11th Revision (ICD-11). This recognition aimed to differentiate between neurotic disorders secondary to stressful situations and somatoform disorders, and disorders specifically associated with stress. The inclusion of CPTSD in the ICD-11 marked the culmination of two decades of research focused on understanding its symptoms, treatments, and risk factors. However, despite the progress made, a comprehensive meta-analysis to elucidate the specific risk factors and impact on the development of CPTSD is still lacking. The objective of this article is to conduct such a meta-analysis. A total of 24 studies were selected for analysis, and the findings revealed several key risk factors associated with the development of CPTSD. The main risk factor identified is having experienced sexual abuse in childhood (k = 12; OR = 2.880). In addition, childhood physical abuse (k = 11; OR = 2.841), experiencing emotional neglect during childhood (k = 5; OR = 2.510), physical abuse throughout life (k = 8; OR = 2.149) and being a woman (k = 13; OR = 1.726) were also significant risk factors.

RESUMO

Introduction: The current study documented levels of anxiety, depression, posttraumatic stress, and COVID-19 fears and impacts among Latinxs living near the U.S.-Mexico border during the COVID-19 pandemic. Methods: Participants of this cross-sectional study were 305 Latinx adults living in the Rio Grande Valley (RGV) who completed an online survey between June and November 2020. Results: About half of participants scored above the cut-off for anxiety (50.2%; GAD-7 scores ≥10) and depression (48.8%; PHQ-9 scores ≥10), and more than a quarter of participants showed clinical levels of posttraumatic stress (27.3%; PCL-5 scores ≥31). Latinxs reported on average 22 types of negative pandemic life impacts on the Epidemic-Pandemic Impacts Inventory. Endorsement of mental health symptoms, severity of COVID-19 fears, and COVID-related life impacts varied based on several demographic characteristics including gender, marital status, educational attainment, employment, income, insurance coverage, vulnerability to COVID-19, and essential worker status. Discussion: Overall, the cross-sectional results of this study revealed that RGV Latinx residents experienced high levels of psychological distress during the pandemic. Results suggest that Latinx women were most affected by the psychological consequences of the pandemic. More research is needed with communities living near the U.S.-Mexico border as they may be particularly vulnerable to mental health problems during the pandemic.

RESUMO

Post-traumatic stress (PTSD) disorder is a mental health condition that can occur after experiencing or witnessing a traumatic event. The 27-F earthquake that struck Chile in 2010 was one such event that had a significant impact on the mental health of the population. A study was conducted to investigate the prevalence of PTSD and its associated factors among survivors of this earthquake. The study was a longitudinal design, involving a sample of 913 patients aged 18 to 75 years who attended 10 Primary Care Centers in Concepción, Chile. The Composite International Diagnostic Interview (CIDI) was used to assess both depressive episodes (DE) and PTSD before and after the earthquake. The study also involved genotyping studies using saliva samples from the participants, specifically focusing on the Val66Met and 5-HTTLPR polymorphisms. Statistical analysis was performed to examine the association between different variables and the presence of PTSD. These variables included demographic factors, family history of psychiatric disorders, DE, childhood maltreatment experiences, and critical traumatic events related to the earthquake. The results showed that the incidence of post-earthquake PTSD was 11.06%. No significant differences were found between the groups of participants who developed post-earthquake PTSD regarding the Val66Met or 5-HTTLPR polymorphisms. However, a significant association was found between the concomitant diagnosis of DE and the development of post-earthquake PTSD. The presence of DE doubled the risk of developing post-earthquake PTSD. The number of traumatic events experienced also had a statistically significant association with an increased risk of developing post-earthquake PTSD. The study's limitations include the potential interference of different DE subtypes, the complexity of quantifying the degree of earthquake exposure experienced by each individual, and events entailing social disruption, such as looting, that can profoundly influence distress. In conclusion, the study found that PTSD following the 27-F earthquake in Chile was associated with a concomitant diagnosis of DE and the number of traumatic events experienced. The study did not find a significant association between PTSD and the Val66Met or 5-HTTLPR polymorphisms. The researchers recommend that mental health professionals should prioritize the detection and treatment of concomitant depressive episodes and exposure to critical traumatic events in survivors of disasters. They also suggest that further research is needed to better understand the relationship between genetic factors and post-disaster PTSD.

RESUMO

Sepsis is associated with several comorbidities in survivors, such as posttraumatic stress disorder (PTSD). This study investigated whether rats that survive sepsis develop the generalization of fear memory as a model of PTSD. Responses to interventions that target the endothelin-1 (ET-1)/cannabinoid system and glial activation in the initial stages of sepsis were evaluated. As a control, we evaluated hyperalgesia before fear conditioning. Sepsis was induced by cecal ligation and puncture (CLP) in Wistar rats. CLP-induced sepsis with one or three punctures resulted in fear generalization in the survivors 13 and 20 days after the CLP procedure, a process that was not associated with hyperalgesia. Septic animals were intracerebroventricularly treated with vehicle, the endothelin receptor A (ETA) antagonist BQ123, the cannabinoid CB1 and CB2 receptor antagonists AM251 and AM630, respectively, and the glial blocker minocycline 4 h after CLP. The blockade of either CB1 or ETA receptors increased the survival rate, but only the former reversed fear memory generalization. The endothelinergic system blockade is important for improving survival but not for fear memory. Treatment with the CB2 receptor antagonist or minocycline also reversed the generalization of fear memory but did not increase the survival rate that was associated with CLP. Minocycline treatment also reduced tumor necrosis factor-α levels in the hippocampus suggesting that neuroinflammation is important for the generalization of fear memory induced by CLP. The influence of CLP on the generalization of fear memory was not related to Arc protein expression, a regulator of synaptic plasticity, in the dorsal hippocampus.

RESUMO

Introdução: este artigo apresenta a constituição psíquica e linguística de um jovem autista, proveniente de uma família de imigrantes em situação de pós-guerra, em que entram em questão temas como o luto, a constituição psíquica transgeracional, e a presença de angústias no processo de desenvolvimento da criança em uma situação singular que é a presença do autismo. Objetivo: analisar os efeitos singulares da imigração e multiculturalismo em um caso de autismo e sua evolução terapêutica. Método: estudo de caso longitudinal, que utilizou diário clínico e filmagens de sessões com observações do desenvolvimento de Rafael, desde os dezoito meses até a idade adulta. Como abordagem terapêutica e análise dos resultados, foram utilizados aportes da constituição psíquica da teoria psicanalítica, e sobre o desenvolvimento linguístico em uma perspectiva enunciativa. Resultados: O multiculturalismo acarretava um desafio maior ao processo de aquisição da linguagem por parte da criança com autismo, enquanto o silêncio consequente da dor do luto, presente nos adultos, dificultava a troca verbal e atrasava sua constituição psíquica. O autismo, por sua vez, apresentou-se como transtornos qualitativos na comunicação, necessitando maior investimento por parte de seus cuidadores para que a aquisição da linguagem se desse, pois o paciente precisou ser fisgado para a nossa cultura. Conclusão: Diante de todo esse quadro, o caso clínico demonstra a importância do suporte terapêutico à família e do investimento contínuo na subjetivação, considerando e valorizando os diferentes códigos culturais que compõem o núcleo familiar.

Introduction: this article presents the psychic and linguistic constitution of an autistic young man, from a post-war immigrant family, in which themes such as mourning, the transgenerational psychic constitution, and the presence of anxieties in the process come into question of the child development in a unique situation that is the presence of autism. Objective: to analyze the unique effects of immigration and multiculturalism in a case of autism and its therapeutic evolution. Method: longitudinal case study, which used a clinical diary and footage of sessions with observations of the development of R. from eighteen months to adulthood. As a therapeutic approach and analysis of results, contributions from the psychic constitution of psychoanalytic theory, and on linguistic development in an enunciative perspective, were used. Results: Multiculturalism posed a greater challenge to the process of language acquisition by the child with autism, while the consequent silence of the pain of grief, present in adults, hindered verbal exchange and delayed their psychic constitution. Autism, in turn, presented itself as qualitative disorders in communication, requiring greater investment on the part of its caregivers for the acquisition of language to take place, as it needed to be hooked for our culture. Conclusion: Given this situation, this clinical case demonstrates the importance of therapeutic support to the family and the continuous investment in subjectivity, considering and valuing the different cultural codes that make up the family nucleus.

RESUMO

Delivering electroconvulsive therapy (ECT) during the reconsolidation of traumatic memories may enhance the treatment efficacy in posttraumatic stress disorder (PTSD). To test this, 14 patients with severe and refractory PTSD were randomly allocated to receive ECT sessions either after retrieving the traumatic (n=8) or a neutral (n=6) memory. We found that delivering ECT after retrieving the traumatic memory enhanced the improvement of PTSD symptoms and the reduction of subjective reactivity to the traumatic memory. Reduction in anxiety and mood symptoms and physiological reactivity to the traumatic memory were observed in the sample as a whole regardless of memory retrieval.

RESUMO

OBJECTIVES: The objective of the study was to evaluate the factors associated with symptoms of posttraumatic stress in mothers during the COVID-19 pandemic. METHODS: Cross-sectional study conducted with mothers of children and adolescents living in Brazil, who answered an online questionnaire containing sociodemographic variables and the Impact of Events Scale-Revised. The Poisson regression model with robust variance was used to identify the factors associated with posttraumatic stress. RESULTS: A percentage of 83.82% of mothers reported an overload in caring for their children during the pandemic. The prevalence of posttraumatic stress symptoms was 39.05%, and this condition was associated with younger age, living in the northern region of the country, using medications, presenting neuropsychiatric comorbidities and being little/more or less satisfied with life. CONCLUSIONS FOR PRACTICE: The mental health situation of mothers during and after the pandemic must be monitored, in order to guarantee public policies capable of optimizing the coping with the situation.

RESUMO

Animal survival depends on cognitive abilities such as learning and memory to adapt to environmental changes. Memory functions require an enhanced activity and connectivity of a particular arrangement of engram neurons, supported by the concerted action of neurons, glia, and vascular cells. The deterioration of the cholinergic system is a common occurrence in neurological conditions exacerbated by aging such as traumatic brain injury (TBI), posttraumatic stress disorder (PTSD), Alzheimer's disease (AD), and Parkinson's disease (PD). Cotinine is a cholinergic modulator with neuroprotective, antidepressant, anti-inflammatory, antioxidant, and memory-enhancing effects. Current evidence suggests Cotinine's beneficial effects on cognition results from the positive modulation of the α7-nicotinic acetylcholine receptors (nAChRs) and the inhibition of the toll-like receptors (TLRs). The α7nAChR affects brain functions by modulating the function of neurons, glia, endothelial, immune, and dendritic cells and regulates inhibitory and excitatory neurotransmission throughout the GABA interneurons. In addition, Cotinine acting on the α7 nAChRs and TLR reduces neuroinflammation by inhibiting the release of pro-inflammatory cytokines by the immune cells. Also, α7nAChRs stimulate signaling pathways supporting structural, biochemical, electrochemical, and cellular changes in the Central nervous system during the cognitive processes, including Neurogenesis. Here, the mechanisms of memory formation as well as potential mechanisms of action of Cotinine on memory preservation in aging and neurological diseases are discussed.

RESUMO

Introduction: Sexual assault and a history of childhood sexual abuse (CSA) are related to posttraumatic stress disorder (PTSD) development. Long interspersed nuclear elements (LINE-1) are transposable elements, and their methylation is used to infer DNA global methylation. DNA methylation can be affected by trauma exposition which in turn would be associated with PTSD. Thus, we investigated if the LINE-1 methylation pattern is related to PTSD symptoms in females with a history of CSA. Methods: This is a case-control study that examined, at baseline (W1), 64 women victims of sexual assault diagnosed with PTSD and 31 patients with PTSD who completed the 1-year follow-up (W2). Participants were categorized into two groups according to the presence of CSA (PTSDCSA+: NW1 = 19, NW2 = 10; PTSDCSA-: NW1 = 45, NW2 = 21). PTSD symptoms (re-experiencing, avoidance, hyperarousal, alterations in cognition/mood) were assessed using the Clinician-Administered PTSD Scale, and the history of CSA was assessed by the Childhood Trauma Questionnaire. LINE-1 methylation was measured in three sites (CpG1, CpG2, CpG3) located in the 5'UTR region using bisulfite conversion followed by pyrosequencing. Linear regression models were performed to test the relation between LINE-1 CpG sites methylation and PTSD symptoms. Results: We found a negative association between CpG2 methylation and hyperarousal symptoms among those in the PTSDCSA+ group in W1 (adjusted p = 0.003) compared to the PTSDCSA- group (p > 0.05). Still, no association was observed between other PTSD symptoms and other CpG sites. Further, in the longitudinal analysis, LINE-1 hypomethylation was no longer observed in PTSD participants exposed to CSA. Conclusion: Our findings suggest that LINE-1 methylation may help understand the relationship between trauma and PTSD. However, more studies are needed to investigate LINE-1 as an epigenetic marker of psychiatric disorders.

RESUMO

OBJECTIVE: Patients with Post-Traumatic Stress Disorder (PTSD) present a variety of symptoms, with different intensities, causing impairments in the individual, social and occupational functioning areas. The aim of this study was to understand the psychodynamic functioning of patients with PTSD, exploring the relationship between symptom severity, quality of life, subjective suffering, conflicts and psychic structure regarding sociodemographic characteristics, styles and defensive mechanisms. METHODS: This is a cross-sectional quantitative study with 60 participants. The following were used: sociodemographic questionnaire, the Operationalized Psychodynamic Diagnosis-2 (OPD-2) and the Defensive Style Questionnaire (DSQ-40). RESULTS: Participants had moderate to high symptom severity, with significant subjective suffering and isolation. The main conflict was Need for care x Self-sufficiency and the level of Total Structure was moderate/low. The use of immature, neurotic, and mature defensive styles was observed. More primitive personality structures, more rigid defenses and greater dependence were found in patients with history of past trauma. Other mental disorders were also associated. CONCLUSION: OPD-2 was effective to assess the psychodynamic functioning characteristics of patients with PTSD. Therapeutic treatment should focus on the psychic structure and not only on symptom control. Prevention strategies should target vulnerability factors and strengthening of protective factors.

RESUMO

The Emotion Regulation Questionnaire (ERQ) is widely used to assess the use of cognitive reappraisal and expressive suppression strategies to regulate negative emotions. The present study evaluates the psychometric properties, reliability and validity of a Chilean adaptation of the ERQ in a large sample of 1543 participants aged between 18 and 87 (38% male, 62% female). The results of the confirmatory factor analysis showed the expected two-factor structure and factorial invariance in relation to gender. Results also indicated adequate internal consistency, test-retest reliability, convergent and predictive validity in predicting posttraumatic stress symptoms and posttraumatic growth six months after the first measurement in a subsample of students exposed to the COVID-19 pandemic. The use of reappraisal was positively associated with general well-being, whereas the use of suppression was positively associated with depressive symptomatology. In terms of posttraumatic consequences, the use of reappraisal was negatively associated with posttraumatic symptomatology and positively associated with posttraumatic growth six months later; in turn, suppression was positively associated with posttraumatic symptomatology and negatively associated with posttraumatic growth six months later. This study demonstrates that the ERQ is a valid and reliable instrument to measure emotional regulation strategies in Chilean adults.

RESUMO

BACKGROUND: There is an increasing concern regarding the mental health of healthcare workers during the COVID-19 pandemic. AIMS: This study aimed to assess the psychological impact of the COVID-19 exposure among Paraguayan healthcare workers. METHODS: A cross-sectional descriptive study has been carried out in five hospitals of Paraguay. Demographic and occupational exposure to COVID-19 were collected through a short questionnaire. Mental health status was assessed with the GAD-7, the PHQ-9, and the PCL-C. Logistic regression was used to determine psychological risk factors. RESULTS: 432 participants were surveyed. 218 (50.46%) were physicians. The prevalence of symptoms of anxiety, depression and PTSD was 48.15, 41.90, and 5.79%, respectively. There were no significant differences in anxiety (128 [29.63%] vs. 80 [18.52%]; p = 0.3303), depression (102 [23.61%] vs. 79 [18.29%]; p = 0.6703), or PTSD (14 [3.24%] vs. 11 [2.55%]; p = 0.8074) between frontline versus second-line workers. Main risk factors associated with psychological distress included work experience <5 years for depression and a COVID-19 positive diagnosis or having family/friends with a COVID-19 positive diagnosis for PTSD. CONCLUSIONS: Paraguayan healthcare workers reported high prevalence of anxiety, depression, and a low prevalence of PTSD. A positive diagnosis of COVID-19 and work experience <5 years are important psychological risk factors.

RESUMO

INTRODUCTION: Coronavirus disease 2019 (COVID-19) is adversely affecting the mental health of patients infected with the virus and the psychological impact on recovered COVID-19 patients is unclear. OBJECTIVES: The study aimed to assess posttraumatic stress disorder (PTSD) and depression among COVID-19 patients after recovery from the disease. METHODS: This cross-sectional study was conducted from November 9, 2020, to December 23, 2020. The study used a telemedicine model to enroll recovered COVID-19 patients from a database of patients provided by the health authorities. The National Stressful Events Survey PTSD Short Scale (NSESSS) for adults was used to assess PTSD symptoms and the Patient Health Questionnaire (PHQ-9) was used to assess depression. RESULTS: The study enrolled 503 recovered COVID-19 patients with a mean age of 41.90 years. The majority were asymptomatic (64.6%), while 21.5% had had moderate to severe forms of the disease. Prevalence rates of PTSD symptoms and depression were 56.9 and 29% respectively. COVID-19 patients with severe forms of the disease were significantly more affected by PTSD symptoms (vs. mild, odds ratio [OR] = 18.7, 95%confidence interval [CI] 9.9-35.5) and depression (vs. mild, OR = 19.8, 95% CI 9.9-39.5). Similarly, patients who required oxygen or ventilator support reported significantly higher rates of PTSD symptoms (vs. managed at home, OR = 17.4, 95% CI 8.3-36.4) and depression (vs. managed at home, OR = 22.0, 95% CI 10.1-47.7). CONCLUSION: This study reports that recovered COVID-19 patients suffered from a significant amount of depression and experienced significant PTSD symptoms. It will help with addressing a major psychological concern among the recovered subjects.

RESUMO

The current coronavirus disease-2019 (COVID-19) pandemic constitutes a significant public health problem worldwide, as well as mental health problems. This study aimed to evaluate the mental health of COVID-19 survivors, considering their sociodemographic, clinical, and immune variables. A cross-sectional and correlational study was conducted on 318 COVID-19 survivors from one hospital in Peru. Through telephone interviews, evaluation of the presence of depressive symptoms using the Patient Health Questionnaire-9, anxiety symptoms through the Generalized Anxiety Disorder-7, somatic symptoms through Patient Health Questionnaire-15, and posttraumatic stress disorder (PTSD) symptoms through Impact of Event Scale-Revised was carried out. Poisson regression analyses were performed with their adjusted variances to calculate the prevalence ratio (PR) with their 95% confidence interval. All regression models were adjusted (PRa) for follow-up time. A significant proportion of patients have depressive (30.9%), anxious (31.1%), somatic (35.2%), and PTSD (29.5%) symptoms. The variables associated with a higher frequency of clinically relevant mental symptoms were female sex, self-perception of greater COVID-19 severity, presence of persistent COVID-19 symptoms, loss of a family member due to COVID-19, and prior psychiatric diagnosis or treatment. In addition, the neutrophil-to-lymphocyte ratio was significantly higher in patients with clinically relevant symptoms of depression. COVID-19 survivors showed a high prevalence of negative mental symptoms. Our findings help to identify patients who are vulnerable and require psychiatric care.
