RESUMO
OBJECTIVES: To investigate prospectively the independent predictors of a minimum clinically important change (MCIC) in quality of life (QOL) after anterior temporal lobectomy (ATL) for drug-resistant mesial temporal lobe epilepsy related to hippocampal sclerosis (MTLE-HS) in Brazilian patients. METHODS: Multiple binary logistic regression analysis was performed to identify the clinical, demographic, radiologic, and electrophysiologic variables independently associated with MCIC in the Quality of Life in Epilepsy-31 Inventory (QOLIE-31) overall score 1 year after ATL in 77 consecutive patients with unilateral MTLE-HS. RESULTS: The overall QOLIE-31 score and all its subscale scores increased significantly (p < 0.0001) 1 year after ATL. In the final logistic regression model, absence of presurgical diagnosis of depression (adjusted odds ratio [OR] 4.4, 95% confidence interval [CI] 1.1-16.1, p = 0.02) and a complete postoperative seizure control (adjusted OR 4.1, 95% CI 1.2-14.5, p = 0.03) were independently associated with improvement equal to or greater than the MCIC in QOL after ATL. The overall model accuracy for MCIC improvement in the QOL was 85.6%, with a 95.2% of sensitivity and 46.7% of specificity. SIGNIFICANCE: These results in Brazilian patients reinforce the external validation of previous findings in Canadian patients showing that presurgical depression and complete seizure control after surgery are independent predictors for meaningful improvement in QOL after ATL, and have implications for the surgical management of MTLE patients.

PURPOSE: The purpose of this study was to investigate the following: i) the objective impairment in neuropsychological tests that were associated with the subjective perception of cognitive function decline in Brazilian patients who underwent mesial temporal lobe epilepsy (MTLE) surgery and ii) the predictive variables for those impaired objective neuropsychological tests. METHODS: Forty-eight adults with MTLE (27 right HS and 23 male) were divided according to their perception of changes (Decline or No-decline) of cognitive function domain of the QOLIE-31 questionnaire applied before and 1year after the ATL. The mean (SD) of changes in the raw score difference of the neuropsychological tests before and after the ATL was compared between Decline and No-decline groups. Receiver Operating Characteristic curves, sensitivity, specificity, and predictive values were used to assess the optimum cutoff points of neuropsychological test score changes to predict patient-reported subjective cognitive decline. KEY FINDINGS: Six (12.5%) patients reported a perception of cognitive function decline after ATL. Among the 25 cognitive tests analyzed, only changes in the Boston Naming Test (BNT) were associated with subjective cognitive decline reported by patients. A reduction of ≥8 points in the raw score of BNT after surgery had 91% of sensitivity and 45% specificity for predicting subjective perception of cognitive function decline by the patient. Left side surgery and age older than 40years were more associated with an important BNT reduction with overall accuracy of 91.7%, 95% predictive ability for no impairment, and 75% for impairment of cognitive function. SIGNIFICANCE: Impairment in word-finding seems to be the objective cognitive finding most relevant to Brazilian patients after mesial temporal lobe epilepsy surgery. Similar to American patients, the side of surgery and age are good predictors for no decline in the BNT, but shows a lower accuracy to predict its decline. If replicated in other populations, the results may have wider implications for the surgical management of patients with drug-resistant MTLE.

Deep brain stimulation (DBS) benefits Parkinson's disease (PD) patient's quality of life specially in domains as mobility, activities of daily living (ADL) and bodily discomfort (BD), but little is known about the variables associated with these HRQOL domains in patients presenting for DBS. The objective is to evaluate variables associated with of HRQOL in a Brazilian sample of PD patients presenting for DBS treatment, specifically in the domains related with motor symptoms. In a cross-sectional study of 59 PD patients evaluated at outpatient Unit for Movement Disorders, multiple linear regression analysis was performed to identify independent variables associated with mobility, ADL and BD domains of the 39-item Parkinson's disease questionnaire (PDQ-39). UPDRS III "on" scores, duration of the disease, age, presence of comorbidities and anxiety and depressive symptoms quantified by hospital anxiety and depression scale (HADS), were the independent variables. In our results, HADS scores were independently associated to mobility domain: ß coefficient 1.36 (95 % CI 0.55-2.15) and BD domain: ß coefficient 1.57 (95 % CI 0.67-2.48). UPDRS III "on" scores were independently associated to mobility domain: 0.42 (95 % CI 0.03-0.81). The model of each multiple linear regression analysis explains 25 % of the mobility domain variability (p < 0.01) and 24 % of the BD domain variability (p < 0.01). Psychiatric symptoms were at least as relevant to quality of life as motor symptoms in PD patients presenting for DBS treatment. The effect of treating these psychiatric symptoms on patients' HRQOL deserves further investigation.

INTRODUCTION: Erectile dysfunction (ED) is often reported by patients with epilepsy and may be related to endocrine system abnormalities, side effects of antiepileptic drugs, psychiatric comorbidities, and family or social difficulties. AIMS: This study aimed to identify independent predictor factors for ED in patients with epilepsy. MAIN OUTCOME MEASURES: the five-question form of the International Index of Erectile Function (IIEF-5). METHODS: Independent predictive factors for ED evaluated by the IIEF-5 questionnaire in 36 patients (mean age: 39 years) with focal epilepsy (mean: 6 seizures/month) were identified by multiple linear regression analysis. RESULTS: Eight (21.1%) patients were asymptomatic. Among the symptomatic patients, 11 (28.9%) had mild dysfunction, 10 (26.3%) had moderate dysfunction, and 9 (23.7%) showed severe ED. The multiple linear regression model including family income (B=0.005; p=0.05), education levels in years (B=0.54; p=0.03), depressive symptoms determined by HADS depression subscale (B=-0.49; p=0.03), and prolactin levels (B=-0.45; p=0.07) showed a moderate association (r=0.64) with the IIEF questionnaire and explained 41% (r(2)=0.41) of its variation. CONCLUSIONS: Erectile dysfunction is highly prevalent in patients with focal epilepsies. Education, depressive symptoms, and prolactin levels can predict erectile dysfunction in up to 41% of patients with epilepsy. This preliminary report justifies further efforts to make a large sample size study to identify independent biomarkers and therapeutic targets for ED treatment in patients with epilepsy.

PURPOSE: This study aimed to evaluate the diagnostic accuracy of the Hamilton Rating Scale for Depression (HRSD), the Beck Depression Inventory (BDI), the Hospital Anxiety and Depression Scale (HADS), and the Hospital Anxiety and Depression Scale-Depression subscale (HADS-D) as diagnostic tests for depressive disorder in drug-resistant mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). METHODS: One hundred three patients with drug-resistant MTLE-HS were enrolled. All patients underwent a neurological examination, interictal and ictal video-electroencephalogram (V-EEG) analyses, and magnetic resonance imaging (MRI). Psychiatric interviews were based on DSM-IV-TR criteria and ILAE Commission of Psychobiology classification as a gold standard; HRSD, BDI, HADS, and HADS-D were used as psychometric diagnostic tests, and receiver operating characteristic (ROC) curves were used to determine the optimal threshold scores. RESULTS: For all the scales, the areas under the curve (AUCs) were approximately 0.8, and they were able to identify depression in this sample. A threshold of ≥9 on the HRSD and a threshold of ≥8 on the HADS-D showed a sensitivity of 70% and specificity of 80%. A threshold of ≥19 on the BDI and HADS-D total showed a sensitivity of 55% and a specificity of approximately 90%. The instruments showed a negative predictive value of approximately 87% and a positive predictive value of approximately 65% for the BDI and HADS total and approximately 60% for the HRSD and HADS-D. CONCLUSIONS: HRSD≥9 and HADS-D≥8 had the best balance between sensitivity (approximately 70%) and specificity (approximately 80%). However, with these thresholds, these diagnostic tests do not appear useful in identifying depressive disorder in this population with epilepsy, and their specificity (approximately 80%) and PPV (approximately 55%) were lower than those of the other scales. We believe that the BDI and HADS total are valid diagnostic tests for depressive disorder in patients with MTLE-HS, as both scales showed acceptable (though not high) specificity and PPV for this type of study.

INTRODUCTION: Changes in hormone blood levels during the acute phase of traumatic brain injury (TBI) have been described in the literature. The objective was to investigate the association among several hormones plasma levels in the acute phase of severe TBI and the hospital mortality rate of male patients. METHODS: The independent association among plasma levels of TSH, LH, FSH, GH, free T4, cortisol, IGF-1 and total testosterone was measured 10 hours and 30 hours after severe TBI and the hospital mortality of 60 consecutive male patients was evaluated. RESULTS: At least one hormonal level abnormality was demonstrated in 3.6-73.1% of patients. The multiple logistic regressions showed a trend for an independent association among hospital mortality and normal or elevated LH levels measured at 10 hours (OR = 3.7, 95% CI = 0.8-16.3, p = 0.08) and 30 hours (OR = 3.9, 95% CI = 0.9-16.7, p = 0.06). Admission with abnormal pupils and a lower Glasgow Coma Score also were independently associated with hospital mortality. CONCLUSION: The hormonal changes are frequent in the acute phase of severe TBI. The hormones plasma levels, excepting the LH, are not highly consistent with the hospital mortality of male patients.

OBJECTIVE: To examine the factor structure, reliability, and validity of the Brazilian version of the Suicide Crisis Inventory (SCI-2) among Brazilian adults. METHODS: The SCI-2 was cross-culturally adapted into Portuguese and administered to 2,265 individuals in the Brazilian community. Confirmatory factor analyses, internal consistency, and convergent and criterion validity against the suicidal narrative, stressful life events, suicidal ideation, and suicide attempts were examined. RESULTS: The revised one-factor model of the SCI-2 resulted in adequate, but not optimal, model fit (χ2[1539] = 31,442.79, p < .001, CFI = .99, TLI = .99, RMSEA = .09, SRMR = .05). The revised five-factor model, on the other hand, demonstrated good fit (χ2[1529] = 14,174.86, p < .001, CFI = 1.00, TLI = 1.00, RMSEA = .06, SRMR = .04). Comparison of these two models indicated that the five-factor exhibited a superior model fit to the one-factor model. The SCI-2 total and subscales showed strong internal consistency, good convergent, and criterion validity in relation to stressful life events, suicidal narrative (except goal disengagement subscale), suicidal ideation, and suicide attempts. CONCLUSIONS: These findings indicate that the Brazilian version of the SCI-2 is a valid tool for measuring symptoms of the Suicide Crisis Syndrome.
RESUMO
INTRODUCTION: Healthcare workers (HCWs) are at an increased risk of suicide compared to non-healthcare workers. This study aims to investigate the association between social support and suicidal ideation and behavior (SIB) during the COVID-19 pandemic among Brazilian HCWs. METHODS: This study utilizes data from 10,885 participants who answered the first (time point 1 - between May and June of 2020) and second (time point 2 - between December 2020 and February 2021) assessments of an online repeated cross-sectional survey for evaluating mental health and quality of life of HCWs during the COVID-19 pandemic in Brazil. Logistic regression analysis was conducted to investigate the relationship between social support as the independent variable (time point 1) and SIB as the outcomes (time point 2). RESULTS: Higher social support was associated with a significantly lower chance of reporting SIB in the month prior to follow-up assessment (adjusted odds ratio [AOR]: 0.71, CI 95% 0.66 - 0.76 and AOR 0.61, CI 95% 0.54 - 0.68, respectively). These associations were independent of sex, age, feelings of loneliness, and self-reported psychiatric disorders. CONCLUSION: Social support is associated with a lower chance of suicidality among HCWs, a protective role that is probably more evident for suicidal behavior.
RESUMO
AIM: To investigate the factor structure, reliability, and validity of the Brazilian version of the Abbreviated Suicidal Narrative Inventory (SNI-38). METHODS: We used an anonymous online questionnaire of the SNI-38 and self-report measures administered between November 2020 and October 2021 in the Brazilian community. Participants were recruited through social media advertisements. Confirmatory factor analysis was carried out to test the factor structure of the SNI-38. In addition, we examined internal consistency, and convergent validity against stressful life events, the suicide crisis syndrome, suicidal ideation, and suicide attempts. RESULTS: 2660 participants were included. The eight-factor model SNI-38 had a good model fit (χ2[637] = 7,473.98, p < .001, CFI = .99, TLI = .99, RMSEA = .07, SRMR = .06); all items were significantly and positively loaded onto their respective factors (factor loadings ≥ .45). Reliability was good to high in all subscales except goal disengagement. Additionally, all subscales - except goal disengagement - were correlated positively which the suicide crisis syndrome, stressful life events, lifetime/past-month suicidal ideation, and lifetime suicide attempts. CONCLUSIONS: These findings provide preliminary support for the validity of the Brazilian version of the SNI-38, being an appropriate and valid tool for measuring suicidal narrative among Brazilian samples.
RESUMO
Huntington's disease (HD) is a progressive and debilitating neurodegenerative disease. There is growing evidence for non-invasive neuromodulation tools as therapeutic strategies in neurodegenerative diseases. This systematic review aims to investigate the effectiveness of noninvasive neuromodulation in HD-associated motor, cognitive, and behavioral symptoms. A comprehensive literature search was conducted in Ovid MEDLINE, Cochrane Central Register of Clinical Trials, Embase, and PsycINFO from inception to 13 July 2021. Case reports, case series, and clinical trials were included while screening/diagnostic tests involving non-invasive neuromodulation, review papers, experimental studies on animal models, other systematic reviews, and meta-analyses were excluded. We have identified 19 studies in the literature investigating the use of ECT, TMS, and tDCS in the treatment of HD. Quality assessments were performed using Joanna Briggs Institute's (JBI's) critical appraisal tools. Eighteen studies showed improvement of HD symptoms, but the results were very heterogeneous considering different intervention techniques and protocols, and domains of symptoms. The most noticeable improvement involved depression and psychosis after ECT protocols. The impact on cognitive and motor symptoms is more controversial. Further investigations are required to determine the therapeutic role of distinct neuromodulation techniques for HD-related symptoms.
RESUMO
Background: Bipolar disorder (BD) is a chronic multifactorial disorder that presents with cognitive impairment as one of its main features, in patients as well as in their first-degree relatives. However, the profile of cognitive dysfunction in BD patients and their relatives is not yet well defined. Various neurocognitive deficits have been proposed as endophenotypes for BD. In the present study, we explored the susceptibility to neurocognitive deficits in BD patients and their siblings compared to healthy controls. Method: A sample consisting of patients diagnosed with BD (N=37), their unaffected siblings (N=30) and a healthy control group (N=39) was assessed using the Brief Assessment of Cognition for Affective Disorders (BAC-A) battery of tests in various cognitive domains: memory, processing speed, working memory, reasoning and problem solving, and affective processing. Results: Compared to healthy controls, BD patients and their unaffected siblings showed deficits in attention and motor speed, or processing speed as measured by the Symbol coding task (p = 0.008), as well as a similar degree of impairment (p = 1.000). Limitations: The lack of statistically significant findings in the other cognitive domains could be related to differences in task difficulty. Most patients were taking psychotropic medication with varying effects on cognition and being treated as outpatients, implying a currently higher level of functioning, which may limit extrapolation of the sample to the general population of BD patients. Conclusions: These results support the view of considering processing speed as an endophenotype for bipolar disorder.
RESUMO
INTRODUCTION: Pandemics have the potential to be considered traumatic event, increasing the risk of developing post-traumatic stress symptoms (PTSS) in HealthCare Workers (HCW). However, few longitudinal studies have evaluated the impact of prolonged exposure to the risk imposed by COVID-19. Our aim was to identify subgroups of HCW with profiles of PTSS, how this profile changed during the pandemic and which variables were related to these changes. METHODS: We evaluated the levels of PTSS and psychological distress in a Brazilian HealthCare Workers' sample (n = 1398) in three waves of assessment: from May to June 2020 (Wave 1), December 2020 to February 2021 (Wave 2) and May to August 2021 (Wave 3), using Latent Profile Analysis (LPA) to identify subgroups with different profiles of symptms, and then, Latent Transition Analysis (LTA) was applied to examine changes in symptom profiles over time, including gender, psychiatric diagnosis history, and pandemic-related fears as covariates. RESULTS: two profiles were identified: high-PTSS profile (Wave 1-23%; Wave 2-64% and Wave 3-73%) and a low-PTSS (Wave 1-77%; Wave 2-36% and Wave 3-27%). Being female, fear of contamination, and fearing financial problems were strong predictors of changes in the profile. In addition, the participants had a high probability of being in the high-PTSS in the long run. CONCLUSION: These results suggests that targeted interventions can mitigate the impact of pandemic. Providing financial support, and psychological support can be beneficial for those with psychiatric diagnoses and experiencing bereavement.

Bipolar disorder (BD) has been previously associated with premature mortality and aging, including acceleration of epigenetic aging. Suicide attempts (SA) are greatly elevated in BD and are associated with decreased lifespan, biological aging, and poorer clinical outcomes. We investigated the relationship between GrimAge, an epigenetic clock trained on time-to-death and associated with mortality and lifespan, and SA in two independent cohorts of BD individuals (discovery cohort - controls (n = 50), BD individuals with (n = 77, BD/SA) and without (n = 67, BD/non-SA) lifetime history of SA; replication cohort - BD/SA (n = 48) and BD/non-SA (n = 47)). An acceleration index for the GrimAge clock (GrimAgeAccel) was computed from blood DNA methylation (DNAm) and compared between groups with multiple general linear models. Differences in epigenetic aging from the discovery cohort were validated in the independent replication cohort. In the discovery cohort, controls, BD/non-SA, and BD/SA significantly differed on GrimAgeAccel (F = 5.424, p = 0.005), with the highest GrimAgeAccel in BD/SA (p = 0.004, BD/SA vs. controls). Within the BD individuals, BD/non-SA and BD/SA differed on GrimAgeAccel in both cohorts (p = 0.008) after covariate adjustment. Finally, DNAm-based surrogates revealed possible involvement of plasminogen activator inhibitor 1, leptin, and smoking pack-years in driving accelerated epigenetic aging. These findings pair with existing evidence that not only BD, but also SA, may be associated with an accelerated biological aging and provide putative biological mechanisms for morbidity and premature mortality in this population.

Schizophrenia and bipolar disorder, two of the most severe psychiatric illnesses, have historically been regarded as dichotomous entities but share many features of the premorbid course, clinical profile, genetic factors and treatment approaches. Studies focusing on neuroimaging findings have received considerable attention, as they plead for an improved understanding of the brain regions involved in the pathophysiology of schizophrenia and bipolar disorder. In this review, we summarize the main magnetic resonance imaging findings in both disorders, aiming at exploring the neuroanatomical and functional similarities and differences between the two. The findings show that gray and white matter structural changes and functional dysconnectivity predominate in the frontal and limbic areas and the frontotemporal circuitry of the brain areas involved in the integration of executive, cognitive and affective functions, commonly affected in both disorders. Available evidence points to a considerable overlap in the affected regions between the two conditions, therefore possibly placing them at opposite ends of a psychosis continuum.
RESUMO
BACKGROUND: Anhedonia - a key symptom of depression - is highly associated with poorer outcomes and suicidal behavior. Alterations in the circuitry of reward-related brain regions have been robustly associated with anhedonia in unipolar depression, but not bipolar disorder (BD). We investigated white matter microstructures associated with anhedonia in participants with BD types I and II and first-degree relatives of patients with BD (BD-siblings). METHODS: Eighty participants (BD types I and II: 56 [70%], and BD-siblings: 24 [30%]) underwent diffusion tensor imaging (DTI); Fractional anisotropy (FA) of different tracts were computed. Anhedonia was assessed using item 8, ("inability to feel'') of the MADRS scale. General linear models were used to compare the FA of different tracts in participants with and without anhedonia controlling for several clinical and demographic variables. RESULTS: The mean age of the sample was 37 (± 11) years old, and 68.8% were female. Participants with anhedonia (32.5%) presented lower mean FA in the left uncinate fasciculus (UF) (p = 0.005), right temporal endings of the superior longitudinal fasciculus (SLFT) (p = 0.04), and in the left and right parietal endings of the superior longitudinal fasciculus (SLFP) (p = 0.003, and p = 0.04, respectively). Similar comparisons between participants with or without current depressive episodes and between participants with or without inner tension according to the MADRS did not show significant differences, specificity of the findings for anhedonia. CONCLUSIONS: Lower FA in the left UF and SLF are potential neuroimaging markers of anhedonia in individuals with BD and high-risk for BD.

INTRODUCTION: The existence of a general factor related to psychiatric symptoms is supported by studies using a variety of methods in both clinical and non-clinical samples. OBJECTIVES: This study aims to evaluate the replicability of the internal structure of the Brief Symptom Inventory in a large Brazilian sample. METHODS: Participants were 6,427 Brazilian subjects (81% female). Mean age was 42.1 years (standard deviation [SD] = 13.6, Min = 13, Max = 80). All participants completed the online version of the Brief Symptom Inventory. This scale presents a general score (GSI) and nine specific clusters of symptoms (depression, anxiety, phobic anxiety, interpersonal sensibility, psychoticism, paranoid ideation, obsessive-compulsive behavior, hostility, and somatization symptoms). RESULTS: Confirmatory factor analysis was performed to assess the factor structure of the BSI. The results showed that the best-fitting model was a bifactor solution and the general factor was the main dimension explaining most of the reliable variability in the data. CONCLUSION: The findings suggest that the BSI's internal structure was replicated in a non-clinical sample and that the general factor is the most reliable score. However, it is necessary to better understand the meaning of the general factor scores in a non-clinical sample to increase interpretability of scores.

OBJECTIVE: To compare the distress level among Brazilian healthcare professionals during the coronavirus disease 2019 (COVID-19) pandemic and estimate risks by sex, age, and occupation. METHODS: In a longitudinal cohort design, a nationally distributed online survey was used to collect data from 10,490 active healthcare professionals who worked during the pandemic. Participants were mostly female, aged 18 to 82 years; 13 different health professions and all states of Brazil were represented. RESULTS: The most frequent professions were psychology, dentistry, and nursing. The Brief Symptom Inventory (BSI) score suggested an increased distress perception among health professionals. Females showed poorer mental health than males, but the absolute rise in Global Severity Index (GSI) score was larger in males than in females. Younger adults reported more symptoms of psychological distress than older adults. The most impacted age group was between 30-39 years. Nurse technicians presented the highest risk of distress. CONCLUSION: Health professionals are essential to overcoming the pandemic; thus, their mental health status should be monitored, and features associated with increased distress should be identified. Our findings suggest distress risk should be stratified by occupation, age, and sex. Health professionals showed an increased distress perception. Women, individuals between the ages of 30 and 39, nursing personnel, and physicians were more likely to report distress compared with other health professionals.

Although the Impact Event Scale-Revised is widely used, its factor structure is still controversial. In addition, its longitudinal measurement invariance (LMI) remains uninvestigated. In this sense, we carried out three studies to investigate its psychometric properties. In Study 1, we evaluated the factorial structure of the scale comparing the different models existing in the literature in Brazilian samples who responded to the instrument during the COVID-19 pandemic. In Study 2, we provide support for a five-factor model throughout convergent validity with psychological distress and sleep problems, and criterion validity between people with diagnostic of mental disorders. Finally, we evaluated the LMI over a 6-month interval. The results indicated that the five-factor model has excellent goodness of fit and holds strict longitudinal invariance. Additionally, internal consistency and stability coefficients indicate that the scale is appropriate to measure posttraumatic stress symptomatology) in nonclinical samples across multiple assessments.

BACKGROUND: Traumatic brain injury (TBI) is a worldwide cause of morbidity and mortality. Pentraxin 3 (PTX3) is a humoral component of the innate immune system which has been studied as a marker of inflammatory, infections or cardiovascular pathologies. To investigate the association between serum levels of PTX3 and the hospital mortality of patients with severe TBI. METHODS: The independent association between serum PTX3 levels after severe TBI (Glasgow Coma Scale, GCS ≤ 8) and hospital mortality was analyzed in a prospective study of 83 consecutive patients by a multiple logistic regression analysis. The leukocyte count in the same sample was analyzed as another marker of inflammatory response. RESULTS: The mean age of patients was 35 years and 85% were male. Serum PTX3 levels were determined 18.0 (SD ± 17.0) h after TBI. Patients who died showed a mean serum PTX3 level of 9.95 µg/ml (SD ± 6.42) in comparison to 5.46 µg/ml (SD ± 4.87) of the survivor group (P = 0.007). Elevated serum PTX3 levels remain significantly associated with mortality (P = 0.04) in the subset of patients with isolated TBI (n = 34). There were no differences in the leukocytes count measured in the same blood sample used for PTX3 determination in survivors and non-survivors (P = 0.56). The final multiple logistic regression model including age, pupillary examination, GCS, associated trauma, and PTX3 levels shows that serum levels of PTX3 which were higher than 10 µg/ml were independently associated with the patients mortality (adjusted OR 3.06, CI 95% 1.03-9.15, P = 0.04). CONCLUSIONS: Serum PTX3 levels after severe TBI are independently associated with higher hospital mortality and may be a useful marker of TBI and its prognosis.
