Metastatic carcinoid

Metastatic carcinoid tumors are relatively chemoresistant (4),(11),(12). However, oxaliplatin in combination with a fluoropyrimidine has Kinase Inhibitor Library demonstrated activity in metastatic neuroendocrine tumors (11),(13),(14). However, we are unaware of any reported case of a patient with metastatic bronchial

carcinoid treated with FOLFOX or XELOX (capecitabine and oxaliplatin in combination). In patients with well differentiated neuroendocrine tumors of the gastro-entero-pancreatic region, the combination of capecitabine and oxaliplatin had a clinical benefit of 78% (30%PR and 48%SD) (15). Somatostatin analogues have been historically Inhibitors,research,lifescience,medical used in patients with NET for symptom palliation. However, Inhibitors,research,lifescience,medical antitumor effect was not demonstrated until recently. The PROMID study group demonstrated that Octreotide LAR significantly improved the PFS from 6.6 to 14.3 months over placebo in patients with functional and non-functional midgut NETs (16). The hypervascular nature of neuroendocrine carcinomas makes them an interesting target for antiangiogenesis agents. In patients with well differentiated pancreatic Inhibitors,research,lifescience,medical neuroendocrine tumor, a recent phase 3 clinical trial with the antiangiogenesis agent sunitinib showed

a significant improvement in PFS over placebo, from 5.5 to 11.3 months (17). In an earlier phase 2 trial, sunitinib demonstrated a clinical benefit of 85.4% (2.4% ORR and 83% SD) in patients with advanced carcinoid; however, the authors did not specify how many patients had stable disease at study entry and the ORR in carcinoids was less than the 16.7% observed in pancreatic NET (18). Bevacizumab with and without IFN has shown activity in neuroendocrine tumors (19),(20). Preliminary data Inhibitors,research,lifescience,medical of a small Phase II clinical trial of FOLFOX and bevacizumab administered every 2 weeks in patients with Inhibitors,research,lifescience,medical advanced and progressive NETs including carcinoid tumors demonstrated promising clinical activity, with 20% PR and 80% SD in the patients with carcinoid (21). The patients received a median of 11 cycles (range 3 to 26) of chemotherapy with 30% Grade

3-4 neutropenia, 38% grade 3-4 fatigue and 23% grade 3-4 hypertension (21). Preliminary results presented at the 2010 ASCO annual meeting from aminophylline another phase II clinical trial of XELOX plus bevacizumab in 31 patients with predominantly metastatic unresectable enteropancreatic NETs showed a clinical benefit ratio of 94% (23% PR and 71% SD). However, it is unclear if any of the patients enrolled in these studies of XELOX or FOLFOX with bevacizumab had metastatic bronchial carcinoid (20)-(22). The MTOR inhibitor everolimus has demonstrated activity in NETs; in phase II clinical trial involving patients with low to intermediate grade NET, everolimus achieved a PR of 17% and 27 % in carcinoid tumors and pancreatic NET respectively (23).

Three of these genes are clearly involved in the process of O-ma

Three of these genes are clearly involved in the process of O-mannosylation (POMT1, POMT2, POMGnT1) (20, 24, 25), while the function of the remaining 3 genes, fukutin, FKRP and LARGE is still not clear (26–29). Of these 6 genes, the most frequently mutated in the Caucasian population is FKRP. While this was the first gene to be associated with an extremely wide range of clinical severity, more recent data suggests that this is also a common theme for mutations in other genes. The FKRP gene Our group originally described mutations in the fukutin-related protein gene (FKRP) in patients with a form of CMD (MDC1C) characterized by onset at

birth or in the first few months of life with profound weakness, markedly Inhibitors,research,lifescience,medical elevated Inhibitors,research,lifescience,medical serum CK and inability to achieve independent ambulation or standing (22). Intelligence was preserved and brain imaging Selleckchem BMS-345541 normal. These patients had a significant reduction of the glycosylation of ADG both on immunocytochemistry and Western blot analysis (22). Shortly after, our group also identified involvement of the FKRP gene in a much milder variant of limb girdle muscular

dystrophy, LGMD2I, which had already been mapped to chromosome 19q13 where the FKRP gene lies (30). In contrast with MDC1C, the onset of the condition in LGMD2I varied from childhood to late adult life; typical patients Inhibitors,research,lifescience,medical with LGMD2I have a hypertrophic phenotype and a proximal Inhibitors,research,lifescience,medical distribution of weakness, limited or no contractures, markedly elevated serum CK and frequent cardiac complications (30–32). Both intelligence and brain imaging are entirely normal. Surprisingly, this form of LGMD was subsequently found to be the most common LGMD variant in the UK population,

due to the high frequency of a C826A mutation, with an estimated heterozygote frequency of ~1:400 (32). Inhibitors,research,lifescience,medical This particular mutation was also found at high frequency in other Caucasian populations, such as in Germany (33) and Scandinavian countries (34), while it was less common in Italians, and even less common in LGMD patients from Brazil (27, 35) and Japan. The expression of glycosylated ADG was only moderately reduced in LGMD2I, in keeping with the less severe muscle involvement compared to children with MDC1C (28). Subsequent studies clarified that Rolziracetam the originally described MDC1C phenotype did not represent the most severe end of the clinical spectrum, as we then identified FKRP mutations in patients with a CMD variant resembling MDC1C but with additional features such as mental retardation and cerebellar dysplasia and cysts on brain MRI (36), followed by the identification of mutations in patients with severe supratentorial cortical dysplasia and structural eye involvement, mimicking classical Muscle-Eye Brain disease (MEB) and Walker Warburg syndrome (WWS) (37). The severity of loss of ADG glycosylation in these patients was more severe than previously found in MDC1C, in keeping with their more severe clinical phenotype.

07). At 30 days, major vascular complications were significantly more frequent with TAVR (11.0% versus 3.2%, P <0.001); adverse events that were more frequent after sAVR included major bleeding (9.3% versus 19.5%, P <0.001) and new-onset atrial fibrillation (8.6% versus 16.0%, P=0.006).16 More patients undergoing TAVR had an improvement in symptoms at 30 days, but by 1 year there was not a significant difference between groups.16 The PARTNER II (Cohort B) Trial is designed to determine the safety and effectiveness of the Edwards 18-Fr SAPIEN XT™ device and

NovaFlex delivery system in inoperable patients with symptomatic critical aortic stenosis.17 Patients will be Inhibitors,research,lifescience,medical randomized in a 2:1 fashion to the SAPIEN XT device or the SAPIEN RetroFlex III device.17 The primary noninferiority endpoints are all-cause mortality, major stroke, and repeat hospitalization at 1 year.17 Self-Expanding TAVR Registries and Randomized Clinical Trials Inhibitors,research,lifescience,medical The Medtronic CoreValve ReValving System (Medtronic, Inc., Minneapolis, MN) consists of a trileaflet porcine pericardial valve and a self-expanding Inhibitors,research,lifescience,medical nitinol support frame. The CoreValve is available for clinical study in the United States in 23-mm, 26-mm, 29-mm, and 31-mm sizes. It is placed by means of an 18-Fr sheath from

the femoral artery or subclavian (axillary) arteries or via direct aortic access. The 18-Fr Safety and Efficacy Study included 126 patients (logistic EuroSCORE=23.4%) with severe aortic valve stenosis.18 The overall technical success rate was 83.1%, and the 30-day Inhibitors,research,lifescience,medical all-cause mortality was 15.2%.18 All-cause mortality was 38.1% at 2 years. There was a significant difference in 2-year mortality between moderate-risk and high-risk groups (27.8% versus 45.8%, respectively; P=0.04), mainly attributable to an increased risk of noncardiac mortality among patients in the high-risk groups.18

Hemodynamic results remained unchanged during Inhibitors,research,lifescience,medical follow-up (mean gradient: 8.5±2.5 mmHg at 30 days and 9.0±3.4 mmHg at 2 years).18 Functional class improved in 80% of patients and remained stable over time. There was no incidence of structural valve deterioration. A Mephenoxalone number of national registries have been developed to evaluate the safety and efficacy of the CoreValve TAVR (Table 3).19-25 These registries have included 2,156 patients, and a preliminary meta-analysis of these registries has been ATM Kinase Inhibitor reported.19-25 Although there were no consistent definitions, procedure success rates ranged from 92.6 to 98%, and 30-day mortality rates ranged from 84.9 to 92.1%.19-25 Table 3 National registries with self-expanding CoreValve TAVR. The United States CoreValve Extreme Risk Pivotal Registry has completed enrollment of 487 patients deemed to have a predicted 30-day surgical mortality risk or irreversible serious morbidity risk that exceeds 50%.

patient information leaflet. Baker et al44 have a different opinion regarding the dose-response curve of SSRIs. They adequately underlined that most dose-response studies expressed a composite result mixing a dose-response for beneficial effects and another one for side effects. With their approach, ie, excluding dropouts, they found a small increase in efficacy with higher doses of ssris# gy grouping the fixeddoses Inhibitors,research,lifescience,medical studies of Wernicke et al16’17 and Fabre and Putman,20 the slope of improvement, as evaluated from response rates, was statistically significant on meta-analysis, ie, 3.1% improvement for each 100 mg/day SSRIs equivalents; this slope was not statistically significant for the individual studies. Thus, Baker et al44 concluded that “study designs better tailored to address the relevant clinical question would test hypotheses more appropriately than previous studies.” Despite Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical the fact that we did not use the technique of meta-analysis in our

review, we propose that the risk of type 2 error concerning a positive dose-response relationship with SSRIs is small. There are several methodological points to discuss in view of the above findings. One concerns the difference between ITT and completer cases analyses. The clinical efficacy of antidepressants estimated according to ITT sample does not favor active treatment. Indeed, completer cases analysis often leads to a higher rate of improvement than ITT analysis. This Etomidate might be attributed to an increased number of dropouts as the dose of antidepressant is increased, as shown by Bollini et al,45 who considered all classes of antidepressants. From a regulatory point of view, the ITT analysis is important to protect the patients from a false, favorable evaluation of beneficial effects of drugs. Therefore, with ITT sample evaluation, one could expect a flat dose-response curve. However, completer cases analyses were generally not different from ITT analyses in these SSRI trials. This means that higher doses of SSRIs are really no more effective than lower doses.

34 Application of Three-Dimensional (3D) Nanostructures in Stem C

34 Application of Three-Dimensional (3D) Nanostructures in Stem Cell Tissue Engineering Great potential resides in the creation of well-controlled, engineered nanodimensional constructs and nanoarchitectures in an attempt to mimic the natural physical and biological environment that promotes tissue find more regeneration and growth through improved cell differentiation and functionality. Langer has defined tissue engineering as “an interdisciplinary field that applies the principles of engineering and life sciences Inhibitors,research,lifescience,medical toward

the development of biological substitutes that restore, maintain, or improve tissue function.”35 The fundamental concept in tissue engineering is the seeding of a scaffold with specific cells in order to drive their growth and development through the application of specific signaling agents including hormones,

proteins, growth media, and environmental stimuli (Figure 1).36 A scaffold is a 3D precise space that supports the cells and allows them to proliferate and differentiate. By developing specifically Inhibitors,research,lifescience,medical tailored nanomaterials with enhanced properties, it is hypothesized Inhibitors,research,lifescience,medical that the scaffold will play a pivotal role in the growth and differentiation of the seeded cell populations. The extracellular matrix (ECM) is defined as any tissue that is not part of a cell. The main components of the ECM are glycoproteins (the most abundant being collagens), proteoglycans, and hyaluronic acid that are hierarchically arranged in a complex topography in the nanometer range.37–39 The scaffold itself is merely an imitation of the ECM found within the body, and it provides a framework for cell-cell interaction and the finite space Inhibitors,research,lifescience,medical that transforms and organizes the cells into 3D tissues and organs (Figure 2).40 Nutrient transport within the scaffold is mainly a function of diffusion and is Inhibitors,research,lifescience,medical of extreme importance in that it controls how the cells proliferate and differentiate. The rate and capacity of the transfer is based on the size, geometry, orientation, interconnectivity, branching, and surface chemistry associated with the

pores and channels, which in turn are dictated by the material composition, Liothyronine Sodium fabrication, and physical arrangement. Conventional polymer-processing techniques have difficulty producing fibers smaller than 10 μm in diameter, which are several orders of magnitude larger than the native ECM topography (50–500 nm) (Figure 3).36 41 Nanofibers with diameters less than 1 μm that have been loaded with suitable growth factors, cells, or bioactive agents have great potential for use in tissue regeneration by providing cells with the necessary physical and chemical cues that drive stem cell fate decisions.41 It may be possible to incorporate these cues into the design of future 3D microenvironments to optimize and facilitate tissue repair and regeneration.

40 Of note, NAA reductions were correlated with Cortisol levels.48 Interestingly,

reduced hippocampal volume has been observed in depressed women with a history of early life trauma49 but not in children with PTSD.50 Hippocampal volume reduction in PTSD may reflect the accumulated toxic effects of repeated exposure to increased glucocorticoid beta-catenin cancer levels or increased Inhibitors,research,lifescience,medical glucocorticoid sensitivity, though recent evidence also suggests that decreased hippocampal volumes might be a pre-existing vulnerability factor for developing PTSD.24 Indeed, hippocampal deficits may promote activation of and failure to terminate stress responses, and may also contribute to impaired extinction of conditioned fear as well as deficits in discriminating between safe and unsafe environmental contexts. Studies using functional neuroimaging have further shown that PTSD patients have deficits in hippocampal activation Inhibitors,research,lifescience,medical during a verbal declarative memory task.51 Both hippocampal atrophy and functional deficits reverse to a considerable extent after treatment with SSRIs,52 which have been demonstrated to increase neurotrophic factors and neurogenesis in some preclinical studies,5 but not others.53 Amygdala

The amygdala is a limbic structure involved in emotional processing Inhibitors,research,lifescience,medical and is critical for the acquisition of fear responses. The functional role of the amygdala in mediating both stress responses and emotional learning implicate its role in the pathophysiology of PTSD. Although there is no clear evidence for structural alterations of the amygdala in PTSD, functional imaging studies have revealed hyper-responsiveness in PTSD during the presentation of stressful scripts, cues,

Inhibitors,research,lifescience,medical and/or trauma reminders.41 PTSD patients further show increased amygdala responses to general emotional stimuli that Inhibitors,research,lifescience,medical are not trauma-associated, such as emotional faces.41 The amygdala also seems to be sensitized to the presentation of subliminally threatening cues in patients with PTSD,54-56 and increased activation of the amygdala has been reported in PTSD patients during fear acquisition in a aminophylline conditioning experiment.57 Given that increased amygdala reactivity has been linked to genetic traits which moderate risk for PTSD,58,59 increased amygdala reactivity may represent a biological risk factor for developing PTSD. Cortex The medial prefrontal cortex (PFC) comprises the anterior cingulate cortex (ACC), subcallosal cortex, and the medial frontal gyrus. The medial PFC exerts inhibitory control over stress responses and emotional reactivity in part by its connections with the amygdala. It further mediates extinction of conditioned fear through active inhibition of acquired fear responses.41 Patients with PTSD exhibit decreased volumes of the frontal cortex,60 including reduced ACC volumes.61,62 This reduction in ACC volume has been correlated with PTSD symptom severity in some studies.

Anatomic location may be helpful in differential diagnosis Intra

Anatomic location may be helpful in differential diagnosis. Intramural leiomyomas most commonly locate in the esophagus and are rare in the stomach and small intestine (126). Morphologically, leiomyomas have brightly eosinophilic cytoplasm with distinct cell borders whereas GISTs

usually reveal syncytial cell morphology. Immunohistochemically, GISTs and leiomyomas share some markers, such as SMA and Inhibitors,research,lifescience,medical h-caldesmon, but spindle cell GISTs are rarely positive for desmin which is more specific for leiomyomas. Rare epithelioid GISTs that lack KIT expression do stain positive for desmin (116). Leiomyomas are negative for CD117. Although gastric schwannomas are not commonly seen, they can be morphologically very similar to certain spindle cell GISTs. Distinct peripheral Inhibitors,research,lifescience,medical cuffing of lymphocytes and strong reactivity with S-100 and GFAP readily differentiate them from GIST in addition to the negativities of CD117 and CD34 (127). Mesenteric fibrous lesions can be very challenging in terms of diagnosis of itself and confusion with GIST due to the location and gross appearance. Microscopically, intraabdominal desmoid fibromatosis Inhibitors,research,lifescience,medical usually display long sweeping PKA inhibitor fascicles of spindle cells embedded within a collagen matrix with an infiltrating patter at peripheral of the tumor. Immunohistochemical stain of beta-catenin is positive in about 75% of cases (128-130).

Inflammatory myofibroblastic tumors are commonly seen in pediatric or young adult patients and recognized as a mesenteric mass. Microscopically, this Inhibitors,research,lifescience,medical tumor has cellular fascicular fibroblastic/myofibroblastic proliferation with a prominent mixed inflammatory components including significant number of plasma cells. About 50% of tumors express ALK-1 (131), which is essentially negative in GIST. Inflammatory fibroid polyp is a polypoid lesion of mucosa with collagenous or Inhibitors,research,lifescience,medical myxoid stroma admixed with fibroblasts. It can be CD34 positive but should be negative for CD117 and DOG1 (113,114,132). Interestingly, same PDGFRA mutations

as seen in GISTs are also discovered in inflammatory fibroid polyps (133). Histologically, epithelioid the GISTs need to be distinguished from other epithelial or epithelioid tumors including carcinoma, melanoma, glomus tumor, germ cell tumor and clear cell sarcoma. Immunohistochemical studies play a major rule on the differential diagnosis and the evaluation of appropriate immunophenotypic markers in context with morphology in most cases allows an accurate classification (Table 1). Table 1 Immunophenotypic features of gastrointestinal mesenchymal tumors Role of molecular analysis Mutational analysis of the KIT gene including exons 11, 9, 13, and 17, and PDGFRA gene including exons 12, 14, and 18 can be helpful in confirming the diagnosis of GISTs if immunohistochemical studies fail to support the diagnosis (particularly in CD117/DOG1-negative spindle cell suspect cases).

26 At a molecular level, the mutation has effects on the pattern

26 At a molecular level, the mutation has effects on the pattern of genomic

methylation, consistent with the role of ATRX in chromatin remodeling.27 The pleiotropic effects of mutations in MECP2 and ATRX could result from the regulated MG-132 clinical trial expression of a restricted class of genes. Investigation of a syndromic MR condition, CLS, has led to the discovery of the involvement of another signaling pathway in cognitive impairment, Inhibitors,research,lifescience,medical namely the MAPK-activated signaling pathway (MAPK for mitogen-activated protein kinase). CLS is characterized by severe psychomotor retardation, facial and digital physical anomalies, and progressive skeletal deformation. The disorder was mapped by linkage to the region Xp22.2 and mutations discovered in a positional candidate gene RSK2 (also known as RPS6KA3).28 RSK2 mediates growth factor induction of cyclic adenosine monophosphate Inhibitors,research,lifescience,medical response element-binding protein (CREB) phosphorylation, as part of a signaling pathway whereby Ras-MAPK and Ras signals are transmitted to the nucleus to activate gene

expression. Remarkably, mutations in RSK2 give rise to nonsyndromic MR: patients in an XLMR family with neither facial, digital, nor skeletal anomalies compatible with CLS, but with mild MR, have been found to have a mutation in exon 14 of the gene, resulting in a conservative amino acid change.17 The Inhibitors,research,lifescience,medical pathogenesis Inhibitors,research,lifescience,medical remains obscure. Segmental aneusomy syndromes A number of genetic conditions associated with intellectual disability have been found to be due to small chromosomal

deletions or duplications (typically less than 5 megabases) and are known as segmental aneusomy syndromes (sec Tabic II).29 The small size Inhibitors,research,lifescience,medical of some of the regions has enabled a search for dosage-sensitive genes. However, in order to prove that a deleted gene is indeed dosage-sensitive, it has been necessary to find families with point mutations in the gene that segregate with intellectual disability. This has been achieved with Rubinstein-Taybi syndrome (characterized by abnormal craniofacial features, broad thumbs, and intellectual disability), which can arise from monosomy of a small region in 16pl3.3.30 The responsible gene expresses the CREB-binding protein (CBP).31 Unfortunately, this approach has not been so successful many for other segmental aneusomies. Williams-Beuren syndrome is a neurodevelopmental disorder characterized by congenital heart disease, infantile hypercalcemia, dysmorphic facial features, and cognitive disability. It is due to haploinsufficiency of genes in the region 7q11.32 It is known that mutations affecting the elastin gene give rise to the supravalvular aortic stenosis, but there are still at least 15 candidate genes that could be involved in the unusual cognitive profile of the syndrome.

From December 2003 to May 2004 adjuvant chemotherapy with a modified PELF regimen was performed to a total of six cycles. In December 2004 during a clinical follow-up, CT and 18F-FDG-PET-CT showed a retroperitoneal lymph node relapse in the form of a homogeneous solid mass sited at the pancreatic uncinate process, the maximum diameter being 5 cm (Figure 1), with SUVmax =18 at PET-CT (Figure 2). As a candidate for first-line chemotherapy treatment, she was enrolled in the phase II clinical trial

FOLCETUX, receiving cetuximab at an initial dose of 400 mg/m2 i.v. followed by weekly doses of 250 mg/m2, Inhibitors,research,lifescience,medical irinotecan 180 mg/m2 i.v. on day 1, LFA 100 mg/m2 i.v. followed by 5-FU 400 mg/m2 i.v. bolus and 600 mg/m2 i.v. 22-h continuous infusion Inhibitors,research,lifescience,medical on days 1 and 2 every two weeks, to a total of 17 cycles. CT and PET-CT performed after six weeks treatment failed to show any residual disease, with Neratinib order complete radiological (Figure 3) response in accord to RECIST criteria and complete metabolic response (Figure 4). A total of 24 Inhibitors,research,lifescience,medical maintenance administrations with cetuximab alone (250 mg/m2 weekly) were performed, as foreseen by the protocol in responders. A grade 3 skin rash was observed

during treatment. Figure 1 CT baseline. Figure 2 PET-CT baseline. Figure 3 CT after six weeks of FOLFIRI/cetuximab: complete response. Figure 4 PET-CT after six weeks of FOLFIRI/cetuximab: complete metabolic response. In November 2005 elevated serum transaminases (AST =289 U/L; ALT Inhibitors,research,lifescience,medical =321 U/L) and subsequent diagnosis of HCV infection led to suspension of the cetuximab maintenance. The total body CT and PET-CT imaging continued to show no residual metabolic disease at the end

of treatment. In December 2007, since clinical and radiological response continued to be complete, treatment with interferon and ribavirin was started, and discontinued in January 2009. In November 2012 a clinical, radiological (CT) Inhibitors,research,lifescience,medical and metabolic (PET-CT) patient examination proved negative for recurrent GPX6 disease, signifying 95 months’ progression free survival. Discussion Cetuximab, the partially humanized murine anti-EGFR monoclonal antibody, has been the most examined anti-EGFR therapy in gastric cancer. It has low activity as a single agent (5), but the trend is different when it is added to single or double chemotherapy regimens. Eleven non-randomized first line phase II studies (6-16) have evaluated the activity and safety of cetuximab combined with different chemotherapy regimens, showing a response rate ranging from 38-69%, time to progression from 5.0 to 11 months and median overall survival between 8.6 and 16.6 months (Table 1).

Depression Inhibitors,research,lifescience,medical is one of the most pressing public health issues because of its high lifetime prevalence of about 15%, and because it is associated with substantial disability.1 Depression was the fourth leading cause of disease burden in 2000 and accounted for 4.4% of total disabilityadjusted life Inhibitors,research,lifescience,medical years (DALY).1

Depression is projected to be the second leading cause of disease burden worldwide, and the leading cause in high-income countries for DALY in 2030.2 Depression is Inhibitors,research,lifescience,medical also responsible for the greatest proportion of disease burden attributable to nonfatal health outcomes, accounting for almost 12% of total years lived with disability worldwide.2 Often, depression assumes a chronic course, and over time is associated with increasing disability.3,4 Inhibitors,research,lifescience,medical .Furthermore, depression has been shown to be an independent predictor of the development of cardiovascular disease,5 the leading cause of death worldwide. For all of these reasons, it is important to treat depression aggressively. Remission, the virtual

absence of symptoms, is the aim of depression treatment, because remission is associated with better function and a better prognosis than is response without, remission. However, in clinical Ganetespib price trials only about one third of patients achieve remission.6,7 ‘there are several predictors Inhibitors,research,lifescience,medical of nonremission, among which somatic and psychiatric comorbidity have a prominent role. This article will shed some light on the role of somatic and psychiatric comorbidity in incomplete remission in depression. Psychiatric comorbidity In depressed patients, Ribonucleotide reductase psychiatric comorbidity is the rule rather than the exception. In the National Comorbidity Survey replication (NCS-R), nearly three fourths (72%) of participants with lifetime major depressive disorder also met. criteria for at least one of the other DSM-IV disorders assessed in the NCS-R, including about 60% with anxiety disorders and 24% with substance-use disorder.8 Another large epidemiological study (The National Epidemiologic Survey on Alcoholism and Related Condition, NES ARC) found that 40% of depressed patients had a comorbid anxiety disorder and 40% had comorbid alcohol abuse or dependence.
