2005; American Psychiatric Association, 2004]. IM olanzapine is a drug that has basically the same pharmacokinetics as oral olanzapine. The main difference compared with the oral formulation is that, since

absorption is rapid following IM administration, the time to effect onset is shorter [Bergstrom et al. 1999]. In December 2012, IM olanzapine came on the market in Japan. However, there have not been any reports in Japan Inhibitors,research,lifescience,medical clarifying the efficacy and safety of IM olanzapine and IM haloperidol in agitated elderly patients with schizophrenia. In this study, we investigated the clinical efficacy and safety of IM olanzapine and IM haloperidol in agitated elderly patients with schizophrenia. Methods Inhibitors,research,lifescience,medical Subjects The subjects were 23 patients who were being treated on an inpatient basis at the psychiatry departments of Tanzawa

Hospital and had been diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). Elderly schizophrenia patients (age >60 years) with persistence of symptoms receiving antipsychotic monotherapy were enrolled into this study. Inclusion criteria were: all patients had a total score of 14 or higher on the Positive and Negative Syndrome Scale Inhibitors,research,lifescience,medical Excited Component (PANSS-EC) and it was concluded by the treating psychiatrist that the patient needed to be treated with an IM injection; all patients were able to provide informed consent or cooperate with the requirements of the study; and patients had been treated with a stable dose of an oral antipsychotic drug monotherapy for at least 3 months. Exclusion criteria were: patients exhibiting allergic reactions or resistance to olanzapine or haloperidol; and patients with serious internal medicine comorbidities. Patients meeting the Inhibitors,research,lifescience,medical following concomitant therapy criteria were excluded from Inhibitors,research,lifescience,medical this study in order to clarify the difference in the efficacy of IM olanzapine and IM haloperidol: patients receiving oral olanzapine or haloperidol; and patients receiving benzodiazepine receptor agonists within 4 hours prior to IM administration. The IM olanzapine selleck compound injection group (12 subjects) and the IM haloperidol injection group (11

subjects) were recruited separately. There were no other PD184352 (CI-1040) medications besides the study antipsychotic. The study was a nonrandomized, not double-blind, open-labeled, flexible dose, naturalistic observational trial of schizophrenia patients who required an addition to their medication because of acute agitation. The IM olanzapine injection group did not differ in having side effects or symptoms compared with the IM haloperidol injection group. Until November 2012, most patients were receiving the IM haloperidol injection (2.5 or 5.0 mg) and until January 2013, the IM olanzapine injection (5.0, 7.5 or 10.0 mg). This study adhered to the Declaration of Helsinki and received the necessary official approval to be conducted at each hospital site.

Initial (univariate) log-rank tests were performed to determine

Initial (univariate) log-rank tests were SB1518 performed to determine the predictive value of categorized versions of the first post-CRT CA 19-9. Univariate and multivariate statistical methodologies were used to determine significant prognostic factors for overall survival. The Kaplan-Meier method was used to obtain overall survival and

recurrence free survival estimates while survival was compared between groups using the log-rank test. Inhibitors,research,lifescience,medical P values for multiple comparison were adjusted using the method developed by Lausen and Schumacher (13). Values for continuous variables are given as median (range). Values for categorical data are specified as frequency (percent). Statistical Analysis Inhibitors,research,lifescience,medical was performed using SAS Statistical analysis software version 9.2 (SAS Institute Inc, Cary, NC, USA). A nominal significance level of 0.05 was used. Results Patient and treatment characteristics Of 116 patients, 84 underwent CRT and 32 received chemotherapy alone. Of the 84 patients that underwent CRT, 54 patients had available pre and post CRT CA 19-9 levels and a bilirubin of less than 2 mg/dL at the time the CA 19-9 was measured. The characteristics of the patients are shown in Table 1. Table 1 Patient and treatment characteristics The median follow up was 7.15 months (range, 3.0-10.6 months). The median pre-CRT Ca 19-9 level was 363.7 and the median Inhibitors,research,lifescience,medical post CRT CA 19-9 level was 85.5. Median time from the end of RT to post

CRT CA 19-9 was 35.89 days (range, 0.00-168.81 days). CA 19-9 values ranging from 50-1,000 were tested in 50 point increments and % change was tested in 10% increments (Tables 2,​,33). Table 2 First post-CRT CA 19-9 level in

increments of 50 Table 3 Percent change in pre Inhibitors,research,lifescience,medical to post CRT CA 19-9 level Patient characteristics including age, sex, race, performance status, weight loss >10% were tested and not statistically significant on univariate analysis. Tumor and treatment factors including chemo regimen, T stage, node status, grade 3-4 toxicity, tumor >30 mm, Inhibitors,research,lifescience,medical and tumor location were tested and not statistically significant. On univariate analysis, post CRT CA 19-9 <50, postCRT CA 19-9 <85.5, percent change ≥90%, and histologic grade all showed prognostic significance (Table 4). Table 4 Univariate Analysis of prognostic factors associated with survival in patients with locally advanced pancreatic carcinoma The median survival of patients with a postCRT CA 19-9 level <85.5 U/mL was 10.3 months compared with 7.1 months in patients with higher levels Liothyronine Sodium (P=0.0242) (Figure 1). The median survival of patients with a decrease in CA 19-9 of >90% post CRT was 16.3 months compared with 7.5 months in those with a <90% post CRT CA 19-9 change (P=0.0179) (Figure 2). The median survival of patients with a post CRT CA 19-9 levels <50 U/mL was 11.1 months compared with 7.1 months in patients with levels ≥50 U/mL (P=0.0287) Figure 1 Median survival of patients with postCRT CA 19-9 level <85.

The words used for the word association task consist

The words used for the word association task consist

of nouns and verbs; they were selected from a list of the 5000 most commonly used words in English. Subjects look at the see more screen and silently say the first word that comes to mind; the control task consists of looking at a two-digit number on the screen and silently saying it. For both tasks subjects signal that they have responded with a button press. Within a run seven blocks of words (12 words each) alternate with eight blocks of numbers (10 numbers per block). Each word/number is on the screen for 1850 ms, followed by 150 ms of blank screen. For image analysis, scans are corrected for motion using the AFNI algorithm Inhibitors,research,lifescience,medical to align each scan to the first image of the first functional scan. Motion is estimated for each subject as the average maximal displacement of subsequent images from the

Inhibitors,research,lifescience,medical reference image across the six functional scans corresponding to the six runs of the task. Once aligned, the data are normalized by scaling the whole-brain signal intensity to a fixed value of 1000. Functional images are aligned to a 3D structural image. Following spatial normalization, individual functional images are averaged together for each of the two groups using a random effects model. To date we have studied four artists Inhibitors,research,lifescience,medical and three scientists using this design. The artists included three writers and one writer/film-maker who also pioneered the use of digital imaging. The scientists included one neuroscientist and two molecular biologists. Their imaging data for the Word Association Task appears in (Figure 1). Since this is a verbal task, one might expect to see different activity Inhibitors,research,lifescience,medical in the artists than in the scientists. However, the images indicate that the generation of word associations Inhibitors,research,lifescience,medical recruits similar brain regions in both the artist and the scientist groups. At a basic level, it indicates that creative processing may involve the interactions of several regions between both hemispheres, laying to rest the notion that creativity resides primarily

in the right hemisphere.20 While the left hemisphere appears to have larger swathes of more intense activation, this may be attributed to the possibility that a verbal task is likely to recruit more of the left (language) hemisphere. It also appears that the association cortices are heavily recruited in this task in both groups, involving components that perform isothipendyl a variety of specialized associations. Thus, on the anterior portions of the brain, both groups show increased intensity in the left pre- and middle central gyri (Brodmann Area [BA] 6), a region that is central to the supplementary/association motor cortex. This region of activation extends down to the left inferior frontal gyrus. Both regions have been implicated in semantic and phonological processing and “theory of mind ”/perspective.

”6 The naturalistic approach represents essentially all types of observations which are not obtained in randomized clinical trials, but which are obtained during the activities of pharmacovigilance and pharmacoepidemiology. Based on the different approaches used to create the BRA during the life cycle of a drug and in the framework of drug regulations, we discuss how both settings are of interest in this assessment. Naturalistic versus randomized evidence During the first half of the 20th century, the evidence lor the therapeutic efficacy of new drugs, in particular anti-infectious

drugs, was often so obvious that the naturalistic observations of therapeutic Inhibitors,research,lifescience,medical successes in treated patients were sufficient to demonstrate efficacy. However, soon the demonstration of the therapeutic efficacy of new drugs became less obvious, and the need to implement a methodology to demonstrate efficacy appeared necessary.7 Inhibitors,research,lifescience,medical The demonstration of drug efficacyis essentially a comparative exercise in which a new drug is evaluated versus a comparator, a placebo, or a NLG919 reference active drug. The clinical efficacy of a treatment is assessed by clinical trials, the

methodology of which has been developed and perfected since the early experiments of Sir Austin Bradford Hill in the 1950s8; the cornerstone Inhibitors,research,lifescience,medical ol clinical trials is the randomization process which ensures that groups ol patients receiving the different treatments are similar. From a statistical viewpoint, the demonstration of efficacy is based on the rejection of the null hypothesis, ie, that there is no difference between the experimental and the comparator treatments. Several Inhibitors,research,lifescience,medical clinical trial designs are used during drug development and generally a couple of randomized

controlled trials should provide a demonstration of the statistically significant superiority of the experimental treatment over the comparator. For example, Inhibitors,research,lifescience,medical the US Food and Drug Administration (FDA) requires at least two phase III pivotal trials with positive results to allow registration of a new drug.9 Regulatory authorities such as the European Committee for Medicinal Product for Human Use (CHMP) from the European Medicines Agency (EMA) regularly publish guidelines on how to evaluate and demonstrate the efficacy and safety of drugs in different therapeutic medroxyprogesterone indications, for example more than 20 CHMP guidelines set the framework for clinical development and clinical trial methodology lor neuropsychiatrie drugs in Europe. Regulatory agencies rely essentially on randomized controlled trials to support the efficacy evidence. The establishment ol efficacy is achieved at the end of Phase III, when the results of the pivotal trials which are key to support the registration process are available.

Current, therapeutic models tend to mix cognitive and behavioral

Current, therapeutic models tend to mix cognitive and behavioral methods. The patient’s evidence for his or her negative belief is cognitive ly questioned, but. emphasis is also put. on behavioral experiments to

test the irrational assumptions. Treatment, classically involves about, 15 to 20 sessions in individual and/or group. Outcomes The effectiveness of BT on various types of social anxiety has been demonstrated in several controlled trials. Social phobia, as such, attracted the interest of clinical researchers after its inclusion in DSM-III,42-44 and was studied in controlled trials of SST, buy AZD8931 systematic desensitization, and in vivo exposure.92,93 CT, too, Inhibitors,research,lifescience,medical demonstrated its effectiveness in studies using waiting list, Inhibitors,research,lifescience,medical or other therapies as control.94-96 Two studies reported some advantages of CT

combined with exposure over exposure alone,97,98 while one did not.99 Another study100 found, in a mixed sample of socially inadequate and phobic patients, that role playing and exposure were superior to cognitive restructuring at. a 6-month follow-up. Some researchers noticed that the gains of exposure therapy were often limited by the negative influence of cognitive factors that impeded anxiety reduction.101 To deal with this problem, a. study102 designed a Cognitive Behavioral Group Treatment (CBGT), which was compared with a credible placebo: lectures and ST. At a 6month follow-up, CBGT demonstrated clearly higher effects: 75% Inhibitors,research,lifescience,medical of the patients in CBGT were improved versus 40% of those in ST. This was confirmed in follow-ups ranging between 4 and

6 years.103 A dismantling study104 comparing CBGT with Inhibitors,research,lifescience,medical exposure found that, each of the two methods was superior to a waiting list, with a slight, advantage of exposure over CT on some measures. The rate of responders Inhibitors,research,lifescience,medical was not, statistically different in the two active conditions. Surprisingly, there was no greater improvement, on cognitive measures in the CBGT group. At. a 6-month follow-up there was no longer any between-group difference. Another trial105 showed, in limited social phobias, that CT followed by exposure, exposure followed by CT, or the combination of both had the same positive effects without significant, difference at a 3-month follow-up. The same authors106 demonstrated that CT followed by exposure was better than their combination or exposure followed by CT in generalized social phobia, at a 3month follow-up. A meta-analysis107 of 12 CBT and 9 exposure studies STK38 concluded that CBT did not, yield better outcomes than exposure therapy, on self-report measures of social anxiety, cognitive symptoms, and depressed/anxious mood, at posttest and follow-up. Another meta-analysis108 included 42 treatment outcome trials and tested 6 conditions: waiting list, placebo, exposure, CT, CT plus exposure, and SST. All the interventions, including placebo, produced larger effect, sizes than a waiting list, and did not. differ in dropout, proportions (12% to 18%).

Furthermore, the shift to higher iodothyronine levels in euthyroi

Furthermore, the shift to higher iodothyronine levels in euthyroid depressed inpatients, both in the morning35 and in the evening36 may contribute to the blunting of TSH response to TRH.37,38 The presence of a blunted TRH test or an abnormal TSH indicates the need for a biological treatment, while the initial status of these tests

has no predictive value in the choice of given antidepressants. However, patients with the lowest pretreatment evening TSH secretion (basal and after 11 PM TRH stimulation) have been found to have the lowest rate of antidepressant response.39 The reduced TSH values is a “state” Inhibitors,research,lifescience,medical marker of depression since its normalization is associated with remission.39 Conversely, persistence of blunted responses (ie, 8 AM-TSH and/or 11 PM-TSH and/or TSH) during remission could selleckchem represent a “vulnerability” marker of depression. Investigation Inhibitors,research,lifescience,medical of the noradrenergic (NA) system. One of the most consistently reported abnormal findings in depression is a blunted growth hormone

Inhibitors,research,lifescience,medical (GH) response to acute administration of clonidine, a partial α2-adrenoreceptor agonist, in drug-free patients. This abnormality suggests subsensitive postsynaptic α2-adrenoreceptors at the hypothalamic level, via growth hormone-releasing hormone release, linked to an erratic release of norepinephrine.40 This finding has led to a reformulation of the original NA depletion hypothesis of depression into the “noradrenergic dysregulation Inhibitors,research,lifescience,medical hypothesis,”40 which emphasizes a primary subsensitivity or downregulation in nerve terminal α2-adrenoreceptors, leading to impaired negative feedback on the presynaptic neuron, which in turn may induce a disinhibition of NA output and exaggerated NA release in response to any activation of

the catecholaminergic system. However, blunted GH response to clonidine does not appear specific to depression but rather to the “anxiety Inhibitors,research,lifescience,medical spectrum,” since this blunting has also been observed in generalized anxiety disorder,41 panic disorder,42,43 and social phobia.44 It PAK6 has also been argued that deficiencies in noradrenergic function could lead to differential response to noradrenaline and serotonin reuptake inhibitors.45 In a study by Coote et al46 the decreased GH response, before treatment, was correlated with subsequent good clinical response to desipramine (a “noradrenergic” antidepressant). In a recent study, Correa et al47 reported that amitriptyline, which primarily increases noradrenergic function, was more efficacious than fluoxetine in depressed patients showing blunted GH to clonidine at baseline (amitriptyline is at least 100 times most potent than fluoxetine in the inhibition of the noradrenaline transporter48). Taken together, these results suggest that the noradrenergic function might influence response to antidepressant treatment.

3).The suicide attempt methods were classified as nonviolent (drug overdose) or violent (cutting beyond a superficial scratch, jumping from a height, shooting, hanging).19 Neuroendocrine investigations On

day 1, a clonidine (CLO) test was carried out at 9 am, after an overnight fast. A GH assay was performed at -30, -15, 0, 15, 30, 60, 90, 120, and 150 minutes. The change in GH after CLO (5 µg/kg orally) was expressed as the maximum increment above the baseline level (mean of -30, -15, 0 minutes) (AGH). Inhibitors,research,lifescience,medical Subjects who had baseline GH levels >2 ng/mL were excluded. We defined a blunted AGH as a level ≤5 ng/mL.“ A d-FEN test (45 mg orally) was carried out at 9 AM, on day 5, after an overnight fast. An assay of PRL was performed at -30, -15, 0, 60, 120, 180, 240, and 300 minutes. The change in PRL after d-FEN was expressed as the maximum Inhibitors,research,lifescience,medical increment above the level at t0 (ΔPRL), since,

in the morning, PRL concentrations decrease (due to the normal circadian rhythm). We excluded from the study all patients with a baseline PRL greater than 20 ng/mL. We defined a blunted ΔPRL as a level ≤0 ng/mL.20 Patients Inhibitors,research,lifescience,medical were then classified into 4 groups (Table I): group 1 (n=6; 11%) was defined by blunted ΔPRLd-FEN alone; group 2 (n=17; 32%) was defined by blunted ΔGHCLO alone; group 3 (n=9; 18%) had a combination of blunted ΔPRLd-FEN and ΔGHCLO; group 4 (n=21; 39%) had no abnormality in the d-FEN and CLO tests.

Hormonal concentrations were determined by radioimmunoassay techniques (GH; sensitivity: 0.2 ng/mL; intra-assay and inter assay coefficients

of variation: 3.7% and 4.5% [Pharmacia hGH RIA 1 00, Uppsala, Sweden]), or imrnunometric techniques Inhibitors,research,lifescience,medical based on enhanced luminescence (PRL; sensitivity: 1.3 ng/mL; intra-assay and interassay coefficients of variation: 5.5% and 6.0% [Amerlite Prolactin Assay, Amersh am SA, UK]). Data analysis Between-group differences were tested for significance by analysis of variance (Kruskal-Wallis H test), and, where the overall effect was significant, by means of the Mann-Whitney two-tailed test (U test), using Bonferroni’s correction. Correlations between quantitative variables were estimated tuclazepam using the Spearman rank coefficient (p). Categorical data were analyzed by either the χ2 test or Fisher’s exact test. The level of statistical significance was set at P=0.05. The form of multivariate analysis chosen was a factorial correspondence analysis (FCA).21-23 This analysis is based on categorical data recorded in a contingency table, ie, clinical variables (column) in each group defined by neuroendocrine tests (row).

Recurrent postoperative effusive-constrictive pericarditis potent

Recurrent postoperative effusive-constrictive pericarditis potentially associated with steroid discontinuation was suspected and she had steroid medication (1 mg/kg daily) again. The tapering of steroid was more slowly over 8 months with the improvement of symptoms and signs. Chest X-ray showed normalized heart size VE-821 purchase within 1 week (Fig. 1G) and in 6 months Inhibitors,research,lifescience,medical (Fig. 1H) after re-treatment

with steroid. At present, she is free of symptom with warfarin only. Discussion Transient effusive-constrictive pericarditis is a rare complication of open-heart surgery but important disease entity, since these patients are not indicated for pericardiectomy. Transient effusive-constrictive pericarditis was originally described in the English literature by Sagristá-Sauleda et al.1) in 1987. Transient Inhibitors,research,lifescience,medical inflammation or fibrosis of the pericardium associated with viral or bacterial infection or immunologic mechanism after acute effusive pericarditis has been proposed as a mechanism of this transient effusive-constrictive pericarditis.2) In 2004, Haley et al.3) described 36 patients who met the criteria Inhibitors,research,lifescience,medical for the diagnosis of transient constrictive pericarditis. At that reports, they described that the

causes for the transient constrictive pericarditis were diverse and most common cause was prior cardiovascular surgery (25%). In Korea, Yang et al.4) reported 11 patients with transient constrictive pericarditis Inhibitors,research,lifescience,medical in 2001. They showed that tuberculosis (10/11 patients)

was the most important etiology of transient constrictive pericarditis in Korea. Postpericardiotomy syndrome develops days to months after cardiac and pericardial injury.5),6) Management of the postpericardiotomy syndrome is basically symptomatic and random combinations of non-steroidal anti-inflammatory agents, colchicines and steroid have been being applied. Recently, Imazio et al.7) showed that most of recurrent pericarditis might be an autoimmune disease and colchicine plus conventional therapy led to a clinically Inhibitors,research,lifescience,medical important and statistically significant benefit over conventional treatment, decreasing the recurrence rate in patients with a first episode of acute pericarditis.8) But their study included acute pericarditis of diverse causes (idiopathic, viral, and autoimmune causes, including postpericardiotomy syndromes and connective tissue diseases). Thus, it is not certain if their results could be applied to postpericardiotomy syndrome patients. The major either adverse clinical event of postpericardiotomy syndrome is recurrence of pericarditis and optimal management of recurrent postpericardiotomy syndrome has not been also established. Our case is postpericardiotomy syndrome with pericardial effusion and constrictive physiology. After administration of steroid and ibuprofen, the constrictive physiology was dramatically resolved. However, there was a recurrence of constrictive physiology after rapid steroid discontinuation.

Stroke is an important medical problem that requires good management. In medicine, stroke is the most common cause of disability around the world. The recent report on infective stroke is Inhibitors,research,lifescience,medical very interesting.1 Moghtaderi and Alavi-Naini1 pointed out many interesting issues and mentioned a large number of tropical Metabolism inhibitor infections that can cause infective stroke. According to this report, malaria, tuberculosis, cysticercosis, syphilis, Inhibitors,research,lifescience,medical and Chagas disease are important examples of infective stroke.1 In fact, several kinds of tropical infections (i.e. parasitic, bacterial, viral, or fungal infections) can lead to stroke. Moghtaderi and Alavi-Naini

also noted that “Lack of human as well as financial Inhibitors,research,lifescience,medical resources makes it difficult to control and treat the disease properly.”1 Indeed, the epidemiology of stroke in tropical countries is interesting. Gomes and Chalela et al.2 noted that “Cerebrovascular disease is a leading cause of morbidity and mortality in tropical countries.” The authors also added to classical etiologies by mentioning “unusual causative mechanisms”. Tropical Inhibitors,research,lifescience,medical infections comprise an important group that merits due consideration. It has been noted that tropical infections accumulate “up to 10% of the cases of strokes in adults” in tropical countries.3 The predominant tropical infections that can lead to tropical stroke might be different

in different settings. For example, Chagas disease is predominant in South America, whereas gnathostomiasis is predominant in Southeast Asia.3 However, Inhibitors,research,lifescience,medical some tropical infections that can cause stroke such as malaria and cysticercosis can be seen in many tropical as well as non-tropical areas.3 Cell press Of interest, the clinical problems are sometimes underdiagnosed. For sure, this leads to the high mortality among the patients with specific tropical strokes.3 As evidence, del Brutto et al.4 mentioned that “The severity of the neurological picture makes it impossible to identify an specific stroke syndrome and cerebrovascular complications are only recognized on neuroimaging studies or autopsy.” This fact calls for medical attention to the forgotten problem of tropical stroke. Of interest, the problem of cryptogenic stroke still exists and incomplete investigation has been cited as the most important cause of it.5 There is no doubt that those cryptogenic cases can have the exact underlying etiologies as tropical infections.

In nursing homes and among high utilizers of medical services, pa

In nursing homes and among high utilizers of medical services, patients with Rocilinostat in vivo depression incur significant increases in direct costs for medical care.57-60 Longitudinal data demonstrate that depressive symptomatology in elderly primary care patients is associated with increased physician visits, medication use, emergency room visits, and outpatient charges.61,62 Among medical inpatients, major depression has been associated with increased utilization of health care resources, including longer hospital stays and greater mortality, for example, in those undergoing elective Inhibitors,research,lifescience,medical coronary artery bypass grafting.63-65 After discharge, depression accounts for a substantial increase in ambulatory health care

use.66 The general health care sector is by far the principal source of treatment for older persons with

depression. Recently analyzed data from the 1987 National Medical Expenditure Survey show that over 55% of older persons Inhibitors,research,lifescience,medical using mental health care received this care from general physicians. In contrast, less than 3% of individuals over age 65 report having received outpatient treatment from mental health professionals, a proportion lower than that for any other adult age group.67 The scope and responsibility of primary care providers are being expanded and redefined in many health care systems. Primary care providers Inhibitors,research,lifescience,medical are charged with greater responsibility for diagnosis, treatment, and longterm management in all areas of health care,

including care of older patients with mental disorders. That being the case, older people may derive substantial Inhibitors,research,lifescience,medical benefit from increased sensitivity to identification of depression on the part of their primary care physicians. Interventions directed toward improvement, recognition, and treatment, however, have not necessarily translated into added benefit when compared to practice as usual in the primary care setting.68-70 Suicide and late-life depression Suicide rates increase with age in most countries of the world, and Inhibitors,research,lifescience,medical men outnumber women suicide completers by a substantial amount. Recent studies of completed suicide have reinforced the close association with major depressive illness, especially in the elderly.71,72 Electron transport chain With increased age, the relative importance of the contribution of depression to suicide risk is magnified. The typical clinical profile of the older suicide completer is lateonset, nonpsychotic, unipolar depression of moderate severity uncomplicated by substance abuse or personality disorder. Tragically, the depression in these older people was rarely recognized or treated. The failure to recognize and treat depression was not due to restricted access to care. A majority of these depressed suicide victims had seen a health care provider in the last month of life, 39% in the last week, and 20% on the day of suicide.73 ‘ITtie article by Bruce and Pearson in this issue of Dialogues in Clinical Neuroscience examines this topic.
