Assessment of short forms of recurrent atrial extra systoles by echocardiography with left atrial strain in ambulatory patients without organic cardiopathy

Aim

To analyse the potential usefulness and clinical relevance of the assessment by echocardiography with left atrial strain, based on the myocardial atrial deformation curves with speckle-tracking velocity vector imaging (VVI), in the analysis of short-form recurrent atrial extra systoles in ambulatory patients not suffering from organic cardiopathy.

Methods

We designed a descriptive, prospective, and observational study including 270 patients between the ages of 18 and 75 assessed during an outpatient cardiology consultation attended due to palpitations over a period of two years. Using ambulatory electrocardiographic monitoring, we selected cases with short forms of repetitive atrial extrasystole, isolated or recurrentatrial fibrillation and a control group formed by those patients without repetitive ectopia. All patients underwent a thorough echocardiographic study during their first cardiological visit.

Results

The analysis of the dynamic curves segmental deformation generated after an atrial extrasystole can reveal different points of origin of the extrasystole and detect specific anatomical alterations in the interatrial conduction at the level of the Bachmann's fascicle showing different models of electro anatomical activation possibly involved in the appearance of repetitive forms. Higher values of dyssynchrony between the septal and lateral wall and elongation in the time of interatrial electromechanical conduction could also be related to the existence of repetitive ectopic beats.

Conclusions

Our ambulatory study employing the left atrial longitudinal strain, particularly in its segmental analysis, provides new insights into its the usefulness and potential clinical relevance.

Effects of raloxifene on cognition in postmenopausal women with schizophrenia: a 24-week double-blind, randomized, parallel, placebo-controlled trial

We assessed the utility of raloxifene (60 mg/day) as an adjuvant treatment for cognitive symptoms in postmenopausal women with schizophrenia in a 24-week, double-blind, randomized, placebo-controlled study. Patients were recruited from the inpatient and outpatient services of Parc Sanitari Sant Joan de Déu, Hospital Universitari Institut Pere Mata, and Corporació Sanitària Parc Taulí. Seventy eight postmenopausal women with schizophrenia were randomized to either adjunctive raloxifene or placebo. Sixty-eight began the clinical trial (37 women on raloxifene adjunct) and 31 on placebo adjunct. The outcome measures were: memory, attention and executive function. Assessment was conducted at baseline and at week 24. Between groups homogeneity was tested with the Student's t test for continuous variables and/or the Mann-Whitney U test for ordinal variables and the χ² test or Fisher's exact test for categorical variables. The differences between the two groups in neuropsychological test scores were compared using the Student's t test. The sample was homogenous with respect to age, formal education, illness duration and previous pharmacological treatment. The addition of raloxifene to antipsychotic treatment as usual showed no differences in cognitive function. The daily use of 60 mg raloxifene as an adjuvant treatment in postmenopausal women with schizophrenia has no appreciable effect.ClinicalTrials.gov Identifier: NCT01573637.

Heart rate measured in the acute aftermath of trauma can predict post-traumatic stress disorder: A prospective study in motor vehicle accident survivors

Objective

To determine whether increased physiological arousal immediately after trauma or at emergency admission can predict post-traumatic stress disorder (PTSD) in motor vehicle accident (MVA) survivors with physical injuries.

Methods

We included 119 MVA survivors with physical injuries. In this prospective cohort study, heart rate (HR) and blood pressure (BP) were assessed during ambulance transport (T1) and at hospital admission (T2). One and four months after the accident, we assessed patients for PTSD (Davidson trauma scale, confirmed with the structured clinical interview for DSM-IV axis I disorders). Multivariate logistic regression models assessed the relationship between HR or BP and PTSD.

Results

PTSD was diagnosed in 54 (45.4%) patients at 1 month and in 39 (32.8%) at 4 months. In the multivariate analysis, HR at T1 or at T2 predicted PTSD at 1 month (OR=1.156, 95% CI [1.094;1.221] p < 0.0001). Only HR at T1 (not at T2) predicted PTSD at 4 months (OR=1.059, 95% CI [1.013; 1.108] p = 0.012). Injury severity predicted PTSD at 4 months (OR=1.207, 95% CI [1.085; 1.342] p = 0.001). A cut-off of 84 beats per minute yielded a sensitivity of 62.5% and a specificity of 75.0% for PTSD.

Conclusions

HR measured at the scene of MVA and severity of injury predicted PTSD 4 months later.

Telephone Management Program for Patients Discharged From an Emergency Department After a Suicide Attempt: A 5-Year Follow-Up Study in a Spanish Population

AIM

In a previous controlled study, the authors reported on the significant beneficial effects of a telephone intervention program for prevention of suicide attempts by patients for up to 1 year. This study reports the 5-year follow-up data. Outcomes were number of recurrences and time to recurrence.

METHOD

The intervention was carried out on patients discharged from the emergency room (ER) following attempted suicide (Sabadell). It consisted of a systematic, 1-year telephone follow-up program: after 1 week, and thereafter at 1-, 3-, 6-, 9-, and 12-month intervals to assess the risk of suicide and encourage adherence to treatment. The population in the control group (Terrassa) received treatment as usual after discharge, without additional telephone contact.

RESULTS

The effect of reattempt prevention observed in the first year was not maintained over the long term.

CONCLUSION

A telephone management program for patients discharged from an ER after attempted suicide could be considered a useful strategy in delaying further suicide attempts and reducing the rate of reattempts in the first year. However, results showed that the beneficial effects were not maintained at the 5-year follow-up.

Association of antidepressant treatment with emergency admission to medical units for patients 65 years or older

INTRODUCTION

There is increasing evidence relating the presence of depression in seniors and the risk of hospital admission in medical departments from the Emergency Services.

OBJECTIVE

To determine the impact of antidepressant treatment (ATD) as a protective factor for emergency hospitalization in older people.

METHOD

All patients aged 65 and over who required urgent attention for medical reasons at the Emergency Department of the Corporació Sanitària i Universitària Parc Taulí (Sabadell, Barcelona, Spain) for the period between January and October 2012 were included in the study. Sociodemographic variables, alcohol and tobacco use, medical history and psychopharmacological treatment were obtained. The necessary sample size was calculated and a simple randomization was performed. Subsequently, a descriptive statistical analysis and parametric tests were conducted.

RESULTS

A total of 674 patients (53% women) were evaluated, with a mean age of 78.45 years, and 27.6% of the cases (71% women) were receiving ATD. Among the 333 admitted patients (50%), 83 individuals (24.6%) had previously received ATD; this contrasts with the 103 cases (30.6%) of prior ATD treatment among the patients who were not admitted. After comparative analysis, the relationship between previous use of ATD and being admitted to hospital was not statistically significant in our global sample. This relationship was only statistically significant among the group aged 75 and over (neg. sig. 0.012).

CONCLUSIONS

In our study, ATD was associated with a decreased risk of hospital admission for urgent medical conditions in people aged 75 and over. Treating depression may protect the elderly against admission to the Emergency department and may potentially be a quality criterion in preventing complications in this population.

Lack of confirmation of thyroid endophenotype in Bipolar Disorder Type I and their first-degree relatives

BACKGROUND

Among the biological factors associated with the development and outcomes in Bipolar Disorder Type I (BD-I), previous studies have highlighted the involvement of both thyroid function and/or auto-immunity, proposing a thyroid endophenotype. The objective of this study was to determine the presence of thyroid alterations in BD-I and their first-degree relatives (FDR).

METHODOLOGY

Unselected, cross-sectional case-control study with parallel analysis of individuals affected by BD-I (239), their FD-R (131), and 108 healthy controls. Thyroidal functional abnormalities (TSH and free T4) and thyroidal antibodies (thyroglobulin and thyroperoxidase antibodies) were studied. Assessments were carried out in parallel. The sample was described using arithmetic means, standard deviations, percentages and ranges. Chi-square, Student-t tests, ANOVA and Pearson correlation coefficients were used when indicated.

RESULTS

BD-I on actual and/or ever treated with lithium showed significant thyroidal functional abnormalities as compared to their FD-R and healthy controls. This BD-I subgroup showed a significant greater proportion of subjects suffering from subclinical hypothyroidism (22%). The role of gender/lithium interactions was relevant. The groups did not show differences in terms of positivization of thyroidal antibodies.

LIMITATIONS

The crosssectional design and the lack of determination of dietary iodine deficiencies and/or thyroidal ecographical controls may be a drawback.

CONCLUSIONS

The present study supports previous findings on the effect of lithium treatment on thyroidal functional, but did not support previous findings related to a familial association or endophenotype. In addition, the present study did not support a familial aggregation of thyroidal antibodies positivization in pedegrees of BD-I.

Attempted and completed suicide: not what we expected?

BACKGROUND

Suicide attempters and suicide completers are two overlapping but distinct suicide populations. This study aims to present a more accurate characterization by comparing populations of suicide attempters and completers from the same geographical area.

METHODS

Samples and procedure: All cases of attempted suicide treated at the emergency room of the Corporacio Sanitària i Universitària Tauli Parc de Sabadell in 2008 (n=312) were compared with all completed suicides recorded in the same geographical area from 2008 to 2011 (n=86). Hospital and primary care records were reviewed for sociodemographic and clinical variables.

STATISTICAL ANALYSIS

Chi-square, ANOVA, and Mann-Whitney U tests were used to identify characteristics related to suicide completion.

RESULTS

Compared to suicide attempters, suicide completers were more likely to be male (73.3% vs. 37.8%; p<0.001), pensioners (73.7% vs. 23.4%; p<0.001), and people living alone (31.8% vs. 11.4%; p=0.006). Suicide completers more frequently presented somatic problems (71.7 vs. 15.7; p<0.001), Major Depressive Disorder (54.7% vs. 27.9%; p<0.001), and made use of more lethal methods (74.1 vs. 1.9; p<0.001). Suicide completers were more likely to have been followed by a primary care provider (50.0% vs. 16.0%; p<0.001). 92.3% of the suicides committed were completed during the first or second attempt.

LIMITATIONS

Suicide completers were not evaluated using the psychological autopsy method.

CONCLUSIONS

Despite presenting a profile of greater social and clinical severity, suicide completers are less likely to be followed by Mental Health Services than suicide attempters. Current prevention programs should be tailored to the specific profile of suicide completers.

Insight, symptomatic dimensions, and cognition in patients with acute-phase psychosis

AIMS

This study was designed to evaluate the relationship between insight and the severity of psychotic symptomatology in a sample of patients in an acute phase of psychosis, as well as to analyze the relationship between insight and the symptomatic profile of the patient. In addition, the role of general cognitive abilities in this relationship was explored.

METHOD

Cross-sectional observational study of 96 acute psychotic adults. To evaluate psychopathology we used the Positive and Negative Syndrome Scale; for insight, the Scale of Unawareness of Mental Disorder; and for general cognitive abilities, the Screen for Cognitive Impairment in Psychiatry.

RESULTS

Insight showed significant and moderate positive correlations with positive and general symptoms but not with negative symptoms. In the subgroup with positive symptomatic profile, awareness of the disorder and of the effects of medication were positively associated with severity of positive and general psychotic symptoms. Awareness of social consequences of the disease was positively associated with positive symptoms. In the subgroup with a negative symptomatic profile, awareness of the disorder and of the effects of medication were positively associated with severity of positive and general psychotic symptoms. In this subgroup, these relationships were significantly affected by general cognitive abilities.

CONCLUSIONS

Insight was not related with the severity of negative psychotic symptoms. The symptomatic profile of subjects played an important role in determining the relationship between insight and its dimensions and the severity of psychotic symptoms. Cognitive function moderated these relationships only in the negative symptomatic profile.

[Violence against women in mental health departments: Is it relevant for mental health professionals?]

INTRODUCTION

Violence against women (VaW) directly influences their quality of life and mental health. Unfortunately, its influence may be ignored or underestimated by professionals attending these women.

OBJECTIVES

To describe a hospitalized sample of women suffering from emergent VaW who visited the mental health department for other reasons. To evaluate the degree of knowledge about VaW and interventions for VaW taken by health professionals.

METHODS

We performed an observational, prospective study with systematic data collection on all cases of emergent and/or urgent VaW at the Corporació Sanitària Parc Taulí (Sabadell, Spain) from January-December 2004 and January-December 2006. The reference population consisted of 390,000 inhabitants, mostly urban and from the industrial and service economic sectors. A descriptive statistical analysis was performed.

RESULTS

In the two study periods, 218 and 194 women, respectively, were attended for emergent and/or urgent VaW resulting in severe injures and/or medical and/or social assistance. Of these, up to 53 received or had received specialized mental health treatment. Most of these women (69.7%) withdrew from follow-up. We detected a high rate of comorbid abuse or dependence on alcohol (27.3%), benzodiazepines (33.3%) or other drugs of abuse and a high rate of suicide attempts (41.9%) and successful suicides in these periods. VaW was explicitly registered in only 51.1% of the cases and a specific intervention for VaW was documented in only 15.2% of the cases.

CONCLUSIONS

The prevalence of psychiatric and/or psychological disorders was very high in our sample, but the presence of VaW was not always specifically documented or treated.

Clinical and sociodemographic variables associated with the onset of posttraumatic stress disorder in road traffic accidents

Our objective was to identify variables related to the onset of acute posttraumatic stress disorder (PTSD) after a road traffic accident. We evaluated 60 victims of a motor vehicle accident (MVA) in 2004 at 2 months postaccident. Thirty of them had developed PTSD; the other 30 had not developed PTSD. Clinical data, physical injuries, and sociodemographic characteristics were determined in 60 victims. The Davidson Trauma Scale (DTS) and a Structured Clinical Interview for DSM-IV (SCID) were used to evaluate PTSD occurrence. PTSD scores assessed by DTS and SCID at 2 months were significantly and positively associated with female sex, severe physical injuries, perceived social deprivation, and loss of job activity due to the accident. Female sex, severe physical injury, perceived social deprivation, and sick leave were related to the diagnosis of PTSD 2 months after the accident.

[Effectiveness and safety of topiramate in treatment-resistant bipolar disorder]

INTRODUCTION

This study was conducted to evaluate the effectiveness and safety of topiramate as add-on therapy for treatment-resistant bipolar disorder.

METHODS

Twenty-one DSM-IV bipolar patients, considered resistant to treatment with lithium, carbamazepine or valproate, gave informed consent to receive increasing doses of the novel anticonvulsant topiramate as adjunctive therapy for their manic (n= 9), depressive (n= 6), hypomanic (n= 3), mixed (n= 2) or schizoaffective manic (n= 1) symptoms. The dosage of other mood stabilizer drugs remained unchanged throughout the 6-week follow-up. Outcome measures included the YMRS, HDRS-17, and CGI scales. Fifteen out of 21 patients completed the 6-week follow-up.

RESULTS

Six patients (40% of completers, 29% by intention-to-treat) were considered responders to topiramate (> 50% reduction in YMRS or HDRS-17 and a decrease of 2 points in CGI). The drug was less effective in intially depressed patients. Topiramate was well tolerated and only one patient discontinued due to side-effects. The most common adverse effect was paresthesia (n= 2). Ten patients experienced moderate weight loss during the follow-up. The mean topiramate dose at endpoint was 158 mg/day.

CONCLUSIONS

These preliminary results suggest that topiramate may be a useful therapy for bipolar disorders, with promising results even in the most treatment-refractory patients.
