RESUMO

Background: Posttraumatic stress disorder (PTSD) symptoms are known to occur after acute coronary syndrome (ACS). Peritraumatic distress has been indicated as a risk factor for PTSD and can be measured by the Peritraumatic Distress Inventory (PDI). However, no studies have yet measured peritraumatic distress after ACS using the PDI to predict PTSD. Objectives: This prospective cohort study examined the impact of peritraumatic distress on PTSD symptoms at 6 months after ACS. Methods: We used the PDI to assess peritraumatic distress in patients treated for ACS at a teaching hospital in Tokyo within 7 days after percutaneous coronary intervention. They were followed up over the next 6 months and were assessed for PTSD symptoms at 6 months using the Impact of Event Scale-Revised. The association between peritraumatic distress and PTSD symptoms was examined by multiple linear regression analysis. Results: The study enrolled 101 ACS patients, and 97 completed the follow-up assessment. PDI total score was an independent predictor of PTSD symptoms after adjustment for potential covariates (beta = 0.38; p < 0.01). Limitations: The results were obtained from a single teaching hospital and assessment of PTSD symptoms was questionnaire based. Conclusion: We provide the first evidence that PDI score can predict the development of PTSD symptoms in ACS patients. Assessing peritraumatic distress after ACS with the PDI may be useful for initiating early intervention against PTSD symptoms.


Antecedentes: Se sabe que síntomas del trastorno de estrés postraumático (TEPT) se pueden presentar después del síndrome coronario agudo (SCA). El malestar peritraumático se ha señalado como un factor de riesgo de TEPT y puede medirse mediante el Inventario de malestar peritraumático (PDI). Sin embargo, ningún estudio ha medido todavía el malestar peritraumático después de un SCA utilizando el PDI para predecir el TEPT.Objetivos: Este estudio de cohorte prospectivo examinó el impacto del malestar peritraumático en los síntomas del TEPT a los 6 meses después del SCA.Métodos: Utilizamos el PDI para evaluar el malestar peritraumático en pacientes tratados por SCA en un hospital universitario de Tokio dentro de los 7 días posteriores a una intervención coronaria percutánea. Fueron seguidos durante los siguientes 6 meses y se evaluaron los síntomas de TEPT a los 6 meses utilizando la Escala de Impacto de Eventos Revisada. La asociación entre malestar peritraumático y síntomas de TEPT se examinó mediante análisis de regresión lineal múltiple.Resultados: El estudio reclutó a 101 pacientes con SCA y 97 completaron la evaluación de seguimiento. La puntuación total del PDI fue un predictor independiente de los síntomas de TEPT después del ajuste de las posibles covariables potenciales (beta = 0,38; p <0.01).Limitaciones: Los resultados se obtuvieron de un solo hospital universitario y la evaluación de los síntomas del TEPT fueron basadas en un cuestionario.Conclusión: Proporcionamos la primera evidencia de que la puntuación PDI puede predecir el desarrollo de síntomas de TEPT en pacientes con SCA. La evaluación del malestar peritraumático después de un SCA con el PDI puede ser útil para iniciar una intervención temprana contra los síntomas del TEPT.

RESUMO

A 60-year-old man had a malignant left lower lung tumour with no metastases and underwent video-assisted thoracoscopic left lower lobectomy and lymphadenectomy. Pathological examination led to a diagnosis of capicua transcriptional repressor (CIC)-rearranged sarcoma. He has had 3.5 years of recurrence-free survival. CIC-rearranged sarcoma is a Ewing-like sarcoma that shows pathological findings similar to Ewing sarcoma. Most of CIC-rearranged sarcoma is CIC-double homeobox 4 protein (DUX4) fusion. Pulmonary CIC-rearranged sarcoma is extremely rare and has an unfavourable prognosis. However, complete resection can produce prognosis of long-term survival, and thus, surgery is an important option.

RESUMO

Patients with autoimmune diseases (AIDs) may develop lymphoproliferative disorders (LPDs) during treatment with immunosuppressive agents (IS) such as methotrexate (MTX), biological agents, or tacrolimus. Some LPDs in patients with AIDs (AID-LPDs) regress after withdrawal of IS, and a high incidence of Epstein-Barr virus (EBV) positivity in such patients has been reported. To identify characteristics and factors predictive of the response to treatment and disease progression, we retrospectively analyzed clinical and histopathological data for 81 patients with AID-LPDs. Almost all of them (96%) had been treated with MTX. Diffuse large B cell lymphoma was the most common LPD type (61%) and seven patients (9%) had classical Hodgkin lymphoma (CHL). EBV was detected by in situ hybridization with an EBV-encoded small RNA (EBER) probe in 43% of the examined cases. In 59 patients, IS was discontinued as the initial treatment, resulting in regression of LPDs in 69% of them, and multivariate analysis showed that EBER positivity was an independent factor predictive of such regression (p = 0.022). Two-year progression-free survival (PFS) and overall survival for the patients overall were 63% and 83%, respectively. Poor PFS was associated with advanced stage (p = 0.024), worse performance status (PS, p = 0.031), CHL histology (p = 0.013), and reactivation of EBV-related antibodies (p = 0.029). In conclusion, EBV positivity demonstrated using an EBER probe is useful for prediction of successful regression after withdrawal of IS in patients with AID-LPDs. Patients with advanced stage disease, worse PS, CHL histology, or reactivation of EBV-related antibodies should be closely monitored after initial treatment.

RESUMO

Castleman-Kojima disease, also known as idiopathic multicentric Castleman disease with TAFRO syndrome (iMCD-TAFRO), is a recently recognized systemic inflammatory disorder with a characteristic series of clinical symptoms, including thrombocytopenia (T), anasarca (A), fever (F), reticulin fibrosis (R), and organomegaly (O). Patients with iMCD-TAFRO often develop severe abdominal pain, elevated alkaline phosphatase levels, and systemic inflammation, but the etiological factors are unknown. To investigate the potential role of bacterial infection in the pathogenesis of iMCD-TAFRO, we performed polymerase chain reaction (PCR) for the bacterial 16S rRNA gene with DNA extracted from liver specimens of three patients with iMCD-TAFRO, four patients with amyotrophic lateral sclerosis, and seven patients with inflammatory conditions. Sequencing of the PCR product showed 99% DNA sequence identity with Campylobacter jejuni in all three patients with iMCD-TAFRO and in two patients with inflammatory conditions. Immunohistochemical and electron microscopy analyses could not identify C. jejuni in patients with iMCD-TAFRO. The findings indicated that C. jejuni infection is not the pathological cause of iMCD-TAFRO; however, this ubiquitous bacterium may play a role in uncontrolled systemic hypercytokinemia, possibly through the development of cross-reactive autoantibodies.

RESUMO

Cardiovascular disease is a known risk factor for the development of psychiatric disorder and about 20% of patients with acute coronary syndrome (ACS) develop depression. Our previous prospective study showed that serum linoleic acid (LA) level at baseline (admission) is a risk factor for the development of psychiatric disorder 3 months later. However, it was unclear whether serum LA could predict psychiatric disorders after 3 months. Thus, we examined the effects of polyunsaturated fatty acid (PUFA) levels at ACS onset on comorbid psychiatric disorders at 6 months. The study involved a follow-up investigation of the previous prospective cohort study of ACS patients. The sample with complete participant data at 6 months post-ACS comprised 100 patients. On admission, serum n-3 and n-6 PUFA levels were measured by gas chromatography and patients were interviewed to obtain medical information. Eight patients (8%) showed psychiatric disorder at 6 months. The association between psychiatric disorder and serum PUFA concentrations at ACS onset was examined by multivariable logistic regression analysis. Psychiatric disorders were predicted by baseline serum LA level (odds ratio = 7.27, 95% confidence interval = 1.11-47.76), indicating that it is a significant risk factor for the development of psychiatric disorder at 6 months. Thus, dietary education to reduce the intake of LA-containing foods might be useful for preventing psychiatric disorder in the population at high risk for ACS. However, the prevalence of psychiatric disorder, particularly depressive disorder, may have been too low to identify significant differences in PUFA analysis.

RESUMO

BACKGROUND: The pathophysiology of fear of cancer recurrence (FCR), the leading unmet psychological need of cancer survivors, may involve the dysfunctional processing of fear memory. n-3 polyunsaturated fatty acids (PUFAs) have beneficial effects on psychiatric disorders, including depressive disorder and anxiety disorders, and are involved in fear memory processing. We hypothesized that n-3 PUFA composition is associated with FCR in cancer survivors. METHODS: We conducted a cross-sectional study to examine the relationship between n-3 PUFAs and FCR among breast cancer survivors. Adults who had been diagnosed with invasive breast cancer and were not undergoing chemotherapy were asked to participate. Blood PUFA composition was evaluated by using capillary blood. We directly administered the Concerns About Recurrence Scale (CARS) to assess the grade of FCR. RESULTS: Among 126 participants used for the analysis, the mean age (SD) was 58 (11) years and 47% had stage I cancer. Multiple regression analysis controlling for possible confounders, depressive symptoms, and post-traumatic stress disorder (PTSD) symptoms revealed that the alpha-linolenic acid (ALA) level was significantly inversely associated with the average score on the CARS overall fear index (beta = -0.165, p = 0.04). No significant associations were found for other PUFAs. LIMITATIONS: Our findings were obtained from a cross-sectional study in a single institute. CONCLUSION: These findings provide the first evidence of a beneficial effect of ALA on FCR and indicate the need for prospective study of this association. FCR among breast cancer survivors might be controllable by prudent selection of ALA-containing cooking oil.

RESUMO

In contrast to the cumulative evidence suggesting the inverse association of n-3 polyunsaturated fatty acids (PUFAs) with depression, few studies have examined the association of n-6 PUFAs with depression. In particular, no study has examined the relationship between n-6 PUFAs and depression in cancer patients. Thus, we conducted this cross-sectional study to comprehensively examine the association of n-3 and n-6 PUFAs with depressive symptoms in breast cancer survivors. Adults who had been diagnosed with invasive breast cancer and were not undergoing chemotherapy were enrolled. Blood PUFA composition was determined using capillary blood. Depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS). Among 126 participants, the mean age (standard deviation) was 58 (11) years and 47% had stage I cancer. Multiple regression analysis controlling for possible confounders revealed that the level of total n-6 PUFAs and linoleic acid was significantly associated with the HADS total score (beta = 0.175, p = 0.046 for total n-6 PUFAs; beta = 0.174, p = 0.048 for LA). No significant associations were found for other PUFAs. These findings provide the first evidence suggesting that a higher blood level of total n-6 PUFAs and linoleic acid is significantly associated with higher depressive symptoms among breast cancer survivors. Further studies should examine the positive effects of a reduction in n-6 PUFAs on depressive symptoms in breast cancer survivors using prospective studies, including randomized control trials.

RESUMO

BACKGROUND: The oncological effectiveness of preoperative radiotherapy for locally advanced colon cancer is unclear. We report a case of pathological complete response in a patient with locally advanced ascending colon cancer after preoperative radiotherapy following failure of chemotherapy. CASE PRESENTATION: A 65-year-old Japanese woman presented with malaise and hematochezia. A computed tomography (CT) revealed a tumor in the ascending colon which seemed to infiltrate the adjacent structures. She was diagnosed with locally advanced ascending colon cancer stages T4b, N2a, M0, and IIIC. We selected modified FOLFOX6 with panitumumab as neoadjuvant chemotherapy. However, we discontinued the chemotherapy after the 8th cycle because of disease progression and severe adverse effects. The patient then underwent radiotherapy of 60 Gy in 30 fractions, resulting in significant tumor size reduction. One month after the radiotherapy, we performed a right hemicolectomy with multivisceral resection without complications. Histopathologically, we found no residual cancer cells in the resected specimen. The patient remains alive and has not required additional therapies for 24 months, as there are no signs of recurrence. CONCLUSIONS: The present case suggests that preoperative radiotherapy might be an effective treatment options for locally advanced colon cancer.

RESUMO

STUDY OBJECTIVE: To evaluate a new magnetic resonance imaging (MRI) grading system for preoperative differentiation between benign and variant-type uterine leiomyomas including smooth muscle tumors of uncertain malignant potential (STUMPs). DESIGN: Retrospective analysis (Canadian Task Force classification III). SETTING: Teaching hospital (Teine Keijinkai Hospital). PATIENTS: Three-hundred thirteen patient medical records were retrospectively reviewed if treated for uterine myomas and diagnosed with variant type leiomyomas or STUMPs (n = 27) or benign, typical leiomyomas (n = 286) and treated between January 2012 and December 2014. INTERVENTION: Uterine myoma classifications using MRI findings according to a 5-grade system (grades I-V) based on 3 elements. MEASUREMENTS AND MAIN RESULTS: Uterine myoma MRI classifications were based on 3 elements: T2-weighted imaging (high or low), diffusion-weighted imaging (high or low), and apparent diffusion coefficient values (high or low; apparent diffusion coefficient < 1.5 × 10-3 mm2/sec was considered low). Grades I to II were designated as typical or benign leiomyomas, grade III as degenerated leiomyomas, and grades IV to V as variant type leiomyomas or STUMPs. Accuracy levels were 98.9%, 100%, 94.3%, 58.8%, and 41.9% for grades I through V lesions, respectively. The grades were divided into 2 groups to discriminate benign leiomyomas and STUMPs (grades I-III were considered negative and grades IV-V positive). Grades IV to V scored 85.2% for sensitivity, 91.3% for specificity, 47.9% positive predictive value, 98.5% negative predictive value, a 9.745 positive likelihood ratio, and a .162 negative likelihood ratio. CONCLUSION: This novel MRI grading system for uterine myomas may be beneficial in differentiating benign leiomyomas from STUMPs or variant type leiomyomas and could be a future effective presurgical assessment tool.

RESUMO

Empirical evidence is divided on whether n-3 polyunsaturated fatty acid levels are associated with quality of life (QOL). This study investigated the effects of docosahexaenoic acid (DHA) supplementation on QOL in survivors of traumatic injury. In this secondary analysis of a double-blind, randomized controlled trial, we recruited 110 trauma patients (82% men; mean age, 39.6 years) in an intensive care unit. Fifty-three received DHA-rich supplements and 57 received placebo for 12 weeks. We used the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) to assess QOL at the end of intervention. DHA did not significantly affect any QOL domain on the SF-36 after 12 weeks. In the DHA group, changes in the erythrocyte levels of eicosapentaenoic acid (EPA) + DHA and EPA were positively correlated with the SF-36 mental component. DHA did not influence QOL of trauma patients, but increased EPA levels during the trial were associated with better QOL in patients receiving omega-3.

RESUMO

Few studies have investigated the relationship between cortisol diurnal rhythm and cognitive function in healthy young adults, especially for emotional memory. To address this deficiency, this study examined the effect of diurnal cortisol slope (DCS) and heart rate variability (HRV) on emotional memory. Participants included healthy volunteers (44 men and 23 women; mean age 20.60 yrs). Participants were shown emotionally arousing slides and were asked to return to the laboratory one week later where they were given a "surprise" memory test to examine their emotional memory retention. Participants were asked to collect saliva samples at four time points (08:00, 11:00, 15:00, and 20:00) on the experimental days; these samples were used to calculate the DCS. Moreover, HRV was measured during the experiment. The multiple linear regression analysis revealed that declarative memory ability, sleep duration, and the DCS were the final significant determinants for emotional memory enhancement (B = -20.41, 0.05, -48.20, ps < 0.05), with participants having flatter cortisol slopes showing reduced or absent emotional memory enhancement. These findings are discussed in reference to the possible effects of diurnal rhythm mechanisms of the hypothalamus-pituitary-adrenal axis and the autonomic nervous system on emotional memory.

RESUMO

BACKGROUND: Around 20% of patients with acute coronary syndrome (ACS) develop depression. Furthermore, some observational studies revealed baseline polyunsaturated fatty acids (PUFAs) may affect the prognosis of depression after ACS. This prospective cohort study examined the association between psychiatric disorder and PUFAs after ACS. METHODS: Subjects were ACS patients admitted to a Tokyo teaching hospital. Psychiatric morbidity as a primary endpoint was measured using structured interview 3 months after admission. At admission, serum n-3 and n-6 PUFAs were measured by gas chromatography and patients were interviewed to evaluate medical information. Multiple logistic regression analysis was performed to calculate odds ratios (ORs) and 95% confidence intervals to examine the association between PUFAs at baseline and psychiatric disorder after ACS. RESULTS: Between March 2014 and August 2016, 100 patients completed the follow-up assessment. Eleven patients (11%) showed some form of new-onset psychiatric disorder at 3 months, mainly depressive episode (major, 5; minor, 1) and PTSD (full, 1; partial, 2). Psychiatric disorder was predicted by serum linoleic acid level (OR=3.96) and Hospital Anxiety and Depression Scale total score (OR=1.34) at baseline. No significant associations were seen with other PUFAs. LIMITATIONS: The results were obtained from a single hospital and based on a small number of participants. There might be some patients with new-onset psychiatric disorder among the refused patients. CONCLUSIONS: Psychiatric disorder incidence in ACS patients might be lower in Japan than in Western countries. Reduced intake of linoleic acid-containing foods might prevent depression or PTSD after ACS.

RESUMO

BACKGROUND: Psychophysiological symptoms (e.g., pounding heart) are known to be a prominent feature of post-traumatic stress disorder (PTSD). Although omega-3 polyunsaturated fatty acids (PUFAs) have a beneficial potential pharmacological effect of preventing these psychophysiological symptoms, no clinical data is yet available. Therefore, we conducted a randomized, double-blind, placebo-controlled trial of Japanese accident survivors. METHODS: A total of 83 participants received either omega-3 PUFAs (1470mg docosahexaenoic acid and 147mg eicosapentaenoic acid per day) or placebo within 10 days of the accidental injury. After 12-week supplementation, participants performed script-driven imagery of their traumatic event during monitoring of their heart rate and skin conductance. RESULTS: Analysis revealed that heart rate during both rest and script-driven imagery was significantly lower in the omega-3 group than the placebo group, whereas baseline heart rate was comparable between the two groups. LIMITATIONS: The present trial was conducted at a single-center in Japan and psychophysiological symptoms of PTSD in most participants were not serious. CONCLUSION: These findings suggest that post-trauma supplementation of omega-3 PUFAs might be effective for the secondary prevention of psychophysiological symptoms of PTSD.

RESUMO

OBJECTIVES: Although attention has been paid to post-traumatic stress disorder (PTSD) among health care professionals after disasters, the impact of traumatic events on their work has not been elucidated. The aim of this study was to examine whether disaster-related distress, resilience, and post-traumatic growth (PTG) affect work engagement among health care professionals who had been deployed to the areas affected by the Great East Japan Earthquake that occurred on March 11, 2011. METHODS: We recruited disaster medical assistance team members who were engaged in rescue activities after the earthquake. The short version of the Resilience Scale (RS-14) and Peritraumatic Distress Inventory (PDI) were administered one month after the earthquake, and the short form of Posttraumatic Growth Inventory (SF-PTGI) and Utrecht Work Engagement Scale (UWES) were administered four years after the earthquake. Work engagement is composed of vigor, dedication, and absorption. Regression analyses were used to examine the relationship of UWES with RS-14, PDI, and SF-PTGI. RESULTS: We obtained baseline data of 254 participants in April 2011, and 191 (75.2%) completed the follow-up assessment between December 2014 and March 2015. The results showed that RS-14 predicted vigor, dedication, and absorption; in addition, SF-PTGI was positively related with these three parameters (p<0.01 for all). CONCLUSIONS: Resilience at baseline and PTG after rescue activities may increase work engagement among health care professionals after disasters. These findings could be useful for establishing a support system after rescue activities during a large-scale disaster and for managing work-related stress among health care professionals.

RESUMO

A primary cilium is a microtubule-based sensory organelle that plays an important role in human development and disease. However, regulation of Akt in cilia and its role in ciliary development has not been demonstrated. Using yeast two-hybrid screening, we demonstrate that Inversin (INVS) interacts with Akt. Mutation in the INVS gene causes nephronophthisis type II (NPHP2), an autosomal recessive chronic tubulointerstitial nephropathy. Co-immunoprecipitation assays show that Akt interacts with INVS via the C-terminus. In vitro kinase assays demonstrate that Akt phosphorylates INVS at amino acids 864-866 that are required not only for Akt interaction, but also for INVS dimerization. Co-localization of INVS and phosphorylated form of Akt at the basal body is augmented by PDGF-AA Akt-null MEF cells as well as siRNA-mediated inhibition of Akt attenuated ciliary growth, which was reversed by Akt reintroduction. Mutant phosphodead- or NPHP2-related truncated INVS, which lack Akt phosphorylation sites, suppress cell growth and exhibit distorted lumen formation and misalignment of spindle axis during cell division. Further studies will be required for elucidating functional interactions of Akt-INVS at the primary cilia for identifying the molecular mechanisms underlying NPHP2.

RESUMO

OBJECTIVE: This study aimed to evaluate factors associated with post-traumatic stress disorder (PTSD) symptoms and burnout 4 years after the Great East Japan Earthquake among medical rescue workers in Disaster Medical Assistance Teams (DMATs). METHODS: We examined participants' background characteristics, prior health condition, rescue work experiences, and the Peritraumatic Distress Inventory (PDI) score at 1 month after the earthquake. Current psychological condition was assessed by the Impact of Event Scale-Revised and Maslach Burnout Inventory administered 4 years after the earthquake. By applying univariate and multivariate linear regression analyses, we assessed the relative value of the PDI and other baseline variables for PTSD symptoms and burnout at 4 years after the earthquake. RESULTS: We obtained baseline data from 254 participants during April 2 to 22, 2011. Of the 254 participants, 188 (74.0%) completed the follow-up assessment. PDI score 1 month after the earthquake was associated with symptoms of PTSD (ß=0.35, P<.01) and burnout (ß=0.21, P<.01). Stress before deployment was a related factor for burnout 4 years after the earthquake in these medical rescue workers (ß=2.61, P<.04). CONCLUSIONS: It seems important for DMAT headquarters to establish a routine system for assessing the PDI of medical rescue workers after deployment and screen those workers who have high stress prior to deployment (Disaster Med Public Health Preparedness. 2016;10:848-853).

RESUMO

TAFRO syndrome is a systemic inflammatory disorder. TAFRO is an acronym that stands for thrombocytopenia, anasarca, fever, reticulin fibrosis, renal dysfunction, lymphadenopathy and hepatosplenomegaly. There are no reports of TAFRO syndrome describing cholangitis on liver biopsy. Herein, we report the first case of TAFRO syndrome with cholangitis. The patient was a 56-year-old man who presented with sudden onset abdominal pain and fever. His symptoms progressed to generalized edema, thrombocytopenia, hepatomegaly, and acute renal failure. Biopsies taken from the mediastinal lymph nodes and bone marrow showed the mixed type of multicentric Castleman's disease and mild reticulin fibrosis, respectively, compatible with TAFRO syndrome. His symptoms were temporarily relieved by steroid pulse therapy and tocilizumab. Fever and anasarca relapsed in a few weeks, however. He was then administered rituximab which resolved his symptoms almost completely.

RESUMO

We report the case of a 76-year-old man diagnosed with angioimmunoblastic T-cell lymphoma (AITL) with high serum vascular endothelial growth factor (VEGF) preceded by Remitting seronegative symmetrical synovitis with pitting edema syndrome. He suffered respiratory discomfort caused by large amounts of pleural effusion. Interestingly, changes in serum VEGF measured over time were similar to changes in pleural effusion. Whether VEGF is related to the pathological condition of AITL is a very important question.

RESUMO

OBJECTIVE: Docosahexaenoic acid (DHA) might help prevent or attenuate posttraumatic stress disorder (PTSD) symptoms. We examined the efficacy and safety of DHA for preventing PTSD (DSM-IV) after severe accidental injury. METHOD: From December 2008 to August 2013, we conducted a randomized, double-blind, placebo-controlled trial of 110 accident-injured patients consecutively admitted to an intensive care unit of the National Disaster Medical Center in Tokyo, Japan. All patients were taught about their psychological reactions to accidental injury for 20 minutes and were randomly assigned to receive 1,470 mg/d of DHA plus 147 mg/d of eicosapentaenoic acid (EPA; n = 53) or placebo (n = 57) for 12 weeks. The primary outcome was total score on the Clinician-Administered PTSD Scale (CAPS) at 3-month follow-up. Secondary outcomes included PTSD diagnosis (full-blown or partial PTSD). Adherence to the interventions was assessed by erythrocyte fatty acid composition. RESULTS: At 3 months, the CAPS total score revealed no differences between the 2 groups (10.78 in the DHA group vs 9.22 in the placebo group; n = 100; P = .572). We found that 11.1% of the DHA group and 5.5% of the placebo group developed PTSD. The erythrocyte level of DHA and EPA in the DHA group was significantly elevated compared to the placebo group (P < .01). CONCLUSIONS: Docosahexaenoic acid supplementation was not superior to placebo for the secondary prevention of PTSD symptoms at 3 months after severe accidental injury. The efficacy of a different ratio of DHA and EPA and higher doses of omega-3 fatty acids as secondary prevention of PTSD remains to be determined.
