Control group To allow group analysis and evaluation of the inter- and intraindividual variations of cerebral perfusion, a control group of 12 healthy volunteers was included in the study. Within

this group of twelve healthy volunteers (low consumers of 0 to 2 cups of coffee daily) not receiving any drink before the two SPECT examinations, eight and six were randomly selected for comparison with the LC and HC caffeine group, BIBF1120 respectively, while the whole caffeine-consuming group was compared with the totality of the control group. Inhibitors,research,lifescience,medical SPECT procedure The caffeine groups subjects were subjected to two separate morning examinations upon arrival at the hospital: (i) one SPECT study after the placebo beverage; and (ii) one SPECT study after the caffeine containing beverage. Inhibitors,research,lifescience,medical The two beverages were given on two different days at 7-day interval, in a double-blind randomized counterbalanced design. Upon arrival at the clinic, the subjects were invited to relax in a comfortable armchair in a quiet and pleasant room. A venous catheter for tracer injection was immediately inserted into the left Inhibitors,research,lifescience,medical arm, and a first blood sample was taken to measure caffeine levels to check for

compliance to 12 h caffeine abstinence. Heart rate and blood pressure measurements were then performed and the subjects filled in the STAI questionnaire. Then, subjects received the caffeine or placebo drink and were asked to rest in the same surrounding for 45 min. This time was chosen since caffeine reaches peak values in the brain between 45 and 60 min postingestion.3 Thereafter, the subjects underwent the same procedure for the measurement of plasma caffeine levels, cardiovascular parameters, and filled in the STAI Inhibitors,research,lifescience,medical questionnaire again. Immediately afterwards, the tracer, 640-925 MBq99mTc-ethyl cysteinate dimer (ECD, Neurolite, Bristol-Myers Squibb Medical Imaging), was injected into the already inserted venous catheter. The subjects were not allowed to read, write, or talk for 5 min, including the fixation period of

Inhibitors,research,lifescience,medical the radiotracer. The control group subjects were also subjected many to two separate morning SPECT examinations at 7-day intervals, in the same conditions, without any beverage. This procedure was used to evaluate the intrasubject variability between two examinations and to avoid the consequences of variable spontaneous mental activity and/or possible perfusion changes induced by the stressful environment related to SPECT examination. SPECT imaging studies were realized with a low-energy, high-resolution, double-head camera (Helix, Elscint). The camera was operated in the “stop and shoot” mode, with acquisitions at 3° intervals and a total acquisition time of 25 min (120 projections, 642 matrix). The total number of counts was superior to 6 million. Slices were reconstructed by filtered back-projection using a Metz filter (FWMH of 8 mm). Slices were acquired 30 min after the injection of ECD.

Table 4 CMR variables according to BNP levels The high BNP group showed worse survival after corrective surgery for isolated, severe TR Thirty-eight patients underwent tricuspid valve replacement and one patient underwent tricuspid valve repair and annuloplasty. The median duration of follow-up after surgery was 420 days Inhibitors,research,lifescience,medical (range, 11 – 780 days). Five of the 39 patients died after surgery (1 patient in the lower BNP group and 4 patients in the higher BNP group); all of 5 patients died due to congestive heart failure. Kaplan-Meier GW-572016 in vivo curves and log-rank analysis revealed

a significant difference between the 2 BNP groups (p = 0.001)(Fig. 2). The 1-year survival rate was 96 ± 4% in patients with a BNP < 200 pg/mL, and 53 ± 17% in patients with a BNP ≥ 200 pg/dL. Combined events, including Inhibitors,research,lifescience,medical death and readmission due to congestive heart failure, occurred in 12 among

39 patients during the follow-up period. The patients with BNP < 200 pg/mL had fewer events within 1 year following surgery. Kaplan-Meier survival curves and log-rank analysis showed a significant difference between the two groups during follow-up (p = 0.049)(Fig. 3). Fig. 2 Kaplan-Meier survival curve for death after surgery according to BNP level. BNP: B-type natriuretic peptide. Fig. 3 Kaplan-Meier survival curve for death and re-admission Inhibitors,research,lifescience,medical due to heart failure after surgery according to BNP level. BNP: B-type natriuretic peptide. Discussion Inhibitors,research,lifescience,medical This is the first study to determine the BNP levels in patients with severe, isolated TR in relation to CMR parameters, and to evaluate the role of BNP as a surrogate marker to predict future outcomes after surgery. We found that the following: (1) the BNP was determined by the LV EF and RV ESVI in patients with severe, isolated

TR; (2) a BNP ≥ 200 pg/mL was the best cut-off value to predicted poor outcome after corrective surgery; and (3) patients with a BNP ≥ 200 pg/mL had higher mortality and morbidity after surgery. Inhibitors,research,lifescience,medical The occurrence of functional TR after left-sided surgery is not an infrequently event and is well-known to be closely linked to exercise intolerance and to portend a poor prognosis.8),16),17) In an earlier study performed at our institution, corrective TR surgery was associated with a high operative mortality and morbidity.4) Therefore, the decision on whether or not to proceed to TR surgery is Oxalosuccinic acid difficult, which made us search hemodynamic parameters of echocardiography and CMR imaging predicting prognosis in patients with severe TR.3),4) In addition, we would like to have a simple and easily available surrogate marker to predict the prognosis of patients with severe, isolated TR. Patients with severe, isolated TR need repeated evaluation because the isolated functional TR normally occurs long after left-sided surgery.

159 Combined with neurochemical imaging (such as receptor imaging), TMS can be used to probe the role of specific neurotransmitter systems.150 Vagus nerve stimulation Vagus nerve stimulation (VNS) uses a programmable electrical stimulator to provide intermittent stimulation to a patient’s left vagus nerve. VNS was originally FDA-approved for treatment-resistant epilepsy160 and was recently approved for the adjunctive treatment of a major depressive episode that has not responded to at least

four antidepressant medication trials. However, the efficacy data on VNS are mixed. Mood improvements have been reported by epileptic patients receiving VNS,161 and one open Inhibitors,research,lifescience,medical and one double-blind study have shown antidepressant efficacy for VNS in depressed epilepsy patients.162,163 A single open study of VNS in 60 nonepileptic patients with treatment-resistant depression

found a 31% response rate and 15% remission rate after 10 weeks164; response and remission Inhibitors,research,lifescience,medical were generally maintained after at least 1 year of treatment165 and showed further increases after 2 years of treatment.166 However, a large, sham-controlled study failed to show statistically significant Inhibitors,research,lifescience,medical antidepressant effects for active VNS167 after 10 weeks of treatment. After 1 year of active VNS (all sham-treated patients received active VNS after the initial 10-week evaluation period), the response rate increased to 27% and remission rate was 16%. 168 These 1-year response and remission rates were better than those in a medication management, observation-only comparison group of similarly treatment-resistant patients Inhibitors,research,lifescience,medical followed for a similar period of time (13% response and 7% remission in the observation-only group).169 Longer-term response, remission, and relapse data are not currently available for this group of patients. Generally, VNS is safe, well-tolerated, and acceptable to patients. The body of Inhibitors,research,lifescience,medical data, taken together in this very refractory patient population, was sufficient to lead to FDA to approve VNS

for the treatment of pharmacoresistant depression. The potential mechanism(s) of action of VNS are not fully understood. The central projections of the vagus nerve via the nucleus tractus solitarius first innervate multiple brain areas implicated in mood regulation, and functional brain imaging studies have confirmed that VNS alters activity of many of these cortical and subcortical regions.170 VNS may affect function of GABA,171,172 DA,173 and NE,174-177 though conflicting data have been reported.173 These neurotransmitter system effects have not been consistently associated with therapeutic response.171 Deep brain stimulation Deep brain stimulation (DBS) medical involves a small electrical stimulator implanted into a defined brain location which typically provides chronic stimulation.

2001; Schubotz and von Cramon 2003; Schubotz 2007). Such task- and body part-specific activations could explain why MOT was affected by finger tapping: because the brain regions (presumably subregions of the PM) that are engaged in the planning of rhythmic, spatially defined actions (assuming that tapping sequences are spatially coded), as well as the execution of these actions by means of finger and concomitant eye movements, are also engaged in MOT. Inhibitors,research,lifescience,medical Previous fMRI studies have investigated brain activation during MOT (Culham et al. 1998, 2001; Jovicich et al. 2001; Howe et al. 2009). All four studies

compared an MOT condition (subjects had to track a subset of 2–5 out of 8–10 objects) with a passive viewing condition Inhibitors,research,lifescience,medical (moving circles without tracking instruction), revealing several loci of activation in the Transferase inhibitor parietal cortex, such as the anterior and the posterior intraparietal sulcus and the superior parietal

lobule. Importantly, the contrast [MOT > passive viewing] also showed activation in frontal regions, namely in the dorsolateral Inhibitors,research,lifescience,medical frontal cortex (DLFC; Culham et al. 1998, 2001; Howe et al. 2009). Furthermore, there was activation associated with tracking load (increasing activation with increasing number of tracked objects) in the left inferior precentral sulcus (Culham et al. 1998, 2001; Jovicich et al. 2001). Activations in the DLFC have been interpreted to refer to the frontal eye fields (FEF). FEF are crucially involved in oculomotor control (Paus 1996) and processes of spatial attention (Corbetta 1998; also see Discussion Inhibitors,research,lifescience,medical for a review of FEF involvement). Activation in the FEF was thus attributed to generation and suppression of involuntary eye movements and attention shifts during MOT (Culham et al. 1998, 2001;

Howe et al. 2009). Furthermore, Jovicich et al. (2001) interpreted activation in the DLFC to represent an Inhibitors,research,lifescience,medical area they named “primary motor area,” assumed to reflect motor preparations prior to executing a response in form of a button press. Indeed, MOT required a response in the end of each trial, passive viewing did not (Jovicich et al. 2001). The authors discussed that this activation in the primary motor area might have concealed activation in the adjacent FEF. In turn, we propose that activation in the DLFC, as has Carnitine palmitoyltransferase II been found by all four studies, refers to the FEF-adjacent PMd, partly concealed by FEF activation. Similarly, we propose that previously found activation in the inferior precentral sulcus (Culham et al. 2001; Jovicich et al. 2001) indicates involvement of the PMv, possibly reflecting sensorimotor prediction processes. That is, in accordance with previous behavioral results (Franconeri et al. 2006; Trick et al. 2006) and found brain activation maxima (Culham et al. 1998, 2001; Jovicich et al. 2001; Howe et al.

Conflict of Interest: None declared
Background: The technique of vertical dome division or tip defining, involves incising the lateral crura and vestibular skin at or lateral to the

dome or tip defining point. The incision divides the lower lateral cartilage into a lateral segment and a medial segment, which are advanced anteriorly and sutured together to increase tip projection. The present study aimed at assessing a new vertical dome division, which is a modified version of vertical dome technique to decrease nasal tip projection, and increase or decrease nasal tip rotation and other tip deformities. Methods: The medical files of Selleckchem SB525334 patients undergone rhinoplasty from 2003 Inhibitors,research,lifescience,medical to 2008 were retrospectively analyzed. The files were selected from a computerized rhinoplasty database of patients, who had been operated using a modified vertical dome

technique and followed-up for one year or more after the surgery. Results: A total of 3756 patients were operated. Complications related to the nasal Inhibitors,research,lifescience,medical tip such as bossae, bifidity, Inhibitors,research,lifescience,medical persistent tip projection or tip asymmetry was seen in 81 patients (2.1%). Revisions for tip-related problems were performed in 42 patients (1.1%). Conclusions: The findings suggest that the modified vertical dome technique is an effective method for nasal tip deprojection and narrowing via an open approach. The length of follow-up and the large sample size support effectiveness of the technique. Key Words: Vertical dome division, rhinoplasty, nasal cartilage, Inhibitors,research,lifescience,medical modified technique Introduction Successful surgical control of the nasal tip is considered the

most difficult step in rhinoplasty. Nasal tip repositioning techniques are used to modify the existing alar cartilages, and to augment the nasal lobule with grafts or implants. The overprojected nasal tip, commonly called the Pinocchio- or Cyrano de Bergerac–type Inhibitors,research,lifescience,medical nose, is a relatively unusual deformity. Nasal tip projection is defined as the distance that the nasal tip extends anterior to the facial plane.1,2 The degree of tip projection is important to exclude factors that may cause an illusion of overprojected nasal tip such as a deep naso-frontal angle, marked dorsal saddling, retrodisplaced chin, or short upper lip.1,3 The next step in evaluating an overprojected nasal tip is to properly analyze the anatomic factors DNA ligase that contribute to the development of such a deformity.4 The medial and lateral crura make up two cartilaginous arches, which anatomically support the nasal tip. This is achieved through the length and strength of the medial and lateral crura.2-5 The ligamentous attachment of the medial crural footplates to the caudal end of the septal cartilage, the fibrous connections between the upper and lower lateral cartilages, and the interdomal ligament, which spans over the anterior septal angle, support the projection of the nasal tip.

087). Similar to previous studies, they identified one deletion in a case at 1q21.1, a deletion within NRXN1, and four duplications at 16p13.1 in cases, and one in a control subject. However no deletions were observed at 22q11.2 or

15q13.3 loci. In a reverse trend for the 15q11.2 locus, three deletions were observed in controls compared with one in cases. Based on all the above studies, we may summarize that rare CNVs, until recently, were only thought to play an important role in disorders such as mental Inhibitors,research,lifescience,medical retardation and autism. However, it now appears that CNV make a substantial contribution to the BI 6727 understanding of schizophrenia etiology and pathogenesis. Deletions at 1q21.1, 15q11.2, and 15q13.3 might join the ranks of 22q11.2 as uncommon but important chromosomal aberrations that can lead to severe behavioral disturbances including schizophrenia. What next? Conclusions and future directions Despite decades of research effort, our understanding Inhibitors,research,lifescience,medical of the genesis

of schizophrenia remains an enigma. The methods used for mapping susceptibility genes have progressed enormously over the past several years. The genome-wide studies have pointed to the role of both common variants as Inhibitors,research,lifescience,medical well as rare variants in schizophrenia susceptibility. However, the effect size associated with common variants is smaller than initially estimated (OR<1.2) and only rare variants generally have a large effect. Furthermore, the number of total susceptibility variants for schizophrenia may Inhibitors,research,lifescience,medical be in the order of thousands.114 Considering the low effect size observed for the associated SNPs the sample size required for replicating these associations with adequate power Inhibitors,research,lifescience,medical would theoretically be up to 100 000 each of cases and controls. To achieve such sample sizes with detailed and consistent phenotype measurement is a

formidable challenge. It may be that testing broader phenotypes such as psychosis might help the field to collect these large numbers as well as detect genes which overlap between different disorders. However, the opposite approach may also be valid, that is to narrow 4-Aminobutyrate aminotransferase the phenotype to a hopefully more homogeneous subgroup, for example including use of brain imaging measures, electrophysiology, or carefully defined symptom subtypes. A smaller number of genes of greater effect sizes may influence more refined, specific phenotypes. An interesting outcome of the GWAS data analyses is that there appears to be a considerable overlap between schizophrenia and bipolar disorder, consistent with the idea that they exist on a clinical continuum with overlapping symptom dimensions. A recent study in two million Swedish families also observed that schizophrenia and bipolar disorder share susceptibility genes.

2006) and in fetuses in vitro (Vasung et al. 2011). The best results in terms of tractography reconstruction were obtained with the 0.08 threshold. Then a second investigator

expert in fetal neuroradiology (NG) evaluated each of the reconstructed tracts and validated the results. In case of bad scoring by the expert, tracking was redone once, and finally not considered if not approved by the expert at that time. The percentage of rejected reconstructed tractography was 4% (5/119). Diffusion tensor parameters of each bundle Masks of the reconstructed bundles were applied to the parametric maps of ADC, FA, λ1, λ2, and λ3 to compute the DTI parameter Inhibitors,research,lifescience,medical values of each bundle with SPM 5 (Welcome institute, London). The average values of the ADC, the FA, the λ1 = λ//, λ2, and λ3 for the whole reconstructed Inhibitors,research,lifescience,medical bundles were obtained for each tract. The λ were obtained by average the λ2 and λ3 values of each reconstructed tracts ( Statistical analysis Statistical analyses

were performed using the JMP 2008 software (SAS Institute Inc., Cary, NC, USA). Diffusion characteristics of WM Inhibitors,research,lifescience,medical tracts independent of gestational age The means, medians, minima, and maxima of DTI parameters (ADC, FA, λ//, λ) measured on each type of bundles for all fetuses were calculated and selleck chemical compared bundles by bundles using ANOVA (P < 0.05, corrected for multiple comparisons) to assess the differences in diffusion characteristics between the different WM bundles Inhibitors,research,lifescience,medical independently of the gestational age. Variation of WM tract diffusion characteristics according to gestational age For

each DTI parameter of each WM bundle, Z-scores were computed for each subject relative to the mean values and standard deviations of the whole population of fetuses. ANOVA was conducted on these diffusion parameters to evaluate the effect of age and bundle type (statistical threshold P < 0.05 after False Discovery Rate (FDR) correction). Variations of diffusion parameters (ADC, FA, λ//, λ) for each type of WM bundle were modeled as a function of age first by linear regression Inhibitors,research,lifescience,medical (Kasprian et al. 2008) and also by polynomial fitting functions (degree 3) (Schneider et al. Resveratrol 2007). Results Diffusion characteristics of WM tracts independent of gestational age The SNR of b0 images measured in the 17 included fetuses resulted in a mean value of 14.07 ± 3.17. All selected tracts studied were validated by the two experts (EZ, NG) except for five OR (four rights, one left) in four different subjects (age: 27 GW, 34 GW, 34 GW, 35 GW) that were removed for the subsequent analyses. Thus, 34 CSTs, 29 OR, and 17 CC were identified and characterized (Figs. 3 and ​and44). Figure 4 Example of DTI tractography of the CC obtained in utero and in vivo for fetal brain.

2 1 7 Examples of Successful Applications Confined impinging je

2.1.7. Examples of Successful Applications Confined impinging jet systems have been used in our laboratory to consistently produce submicron API suspensions via a continuous process that involves crystallization via the solvent/antisolvent technique to generate supersaturation conditions. Microfliudics Reaction Technology (MRT) was selected for this bottom-up processing since it is based on novel multiple stream inlet capabilities coupled with the impinging jet concept [11–14, 26]. It is designed to produce jet velocities and energy dissipation orders of Inhibitors,research,lifescience,medical magnitude higher than those of conventional impinging

jet reactors. The technology provides precise control of the feed rates, and the subsequent location and intensity of mixing of the reactants. It may provide significant technical and economical advantages due to its process intensification character that minimizes energy requirements, and the proven scalability of the reactor. In our first proof of concept studies performed, nanosuspensions Inhibitors,research,lifescience,medical of several APIs were produced varying the key parameters of the technology [14]. Five different model APIs were used for testing and were selected to belong to different chemical families that exhibit different pharmacological activities. There were two antibiotics (azithromycin and API-2), an antihistamine (loratadine), an anticonvulsant

(oxycarbazepine) Inhibitors,research,lifescience,medical and a non-steroidal anti-inflammatory (NSAIS, API-1). The selleck chemical particle size depended Inhibitors,research,lifescience,medical on the supersaturation ratio and energy dissipation expressed as process pressure. The nanosuspensions were stable with narrow particle size distributions and median particle sizes in the range of 50–760nm. This “bottom up” process was compared to a

“top down” process in which drug nanosuspensions were created as a result of particle size reduction. It was found that the “bottom up” process was substantially more efficient and resulted in smaller particles. This first study did not attempt to identify crystalline structure and therefore no polymorph Inhibitors,research,lifescience,medical selectivity capabilities were evaluated. To accomplish this, two additional, more in depth studies were conducted on single APIs: Carbamazepine (CBZ), an anticonvulsant, Astemizole and Norfloxacin (NFN), an antibacterial agent. The details of the experimental protocols and results are reported in separate papers, CBZ [12] and NFN [11]. A few brief comments are given here to help validate the benefits of bottom up processing with respect to the stated objectives of creating carefully engineered particles with “tunable” characteristics. The NFN nanosuspensions had narrow particle size distributions and median particle sizes in the range of 170–350nm depending on the supersaturation ratio and energy dissipation expressed as process pressure. However, the particle size was found to be insensitive to the presence of the surfactant used.

During the last decade, the issue of pandemic triage has entered

During the last decade, the issue of pandemic triage has entered the discussion of triage [21-23]. The emerging infectious disease like Severe Acute Respiratory c-Met pathway Syndrome (SARS) and Pandemic Influenza have alerted emergency departments to the need for contingency plans. This applies to triage for intensive care services as well. In such public health emergencies, the managerial emphasis shifts from the individual to the population, from “individual” to “statistical” lives, trying Inhibitors,research,lifescience,medical to realize a maximal outcome out of the available resources [24]. Nevertheless, emergency staff continues to be confronted, on a face-to-face

level, with the care for individual patients in need, whom they might not be able to help. Emergency Department Triage Triage is a system of clinical risk management employed in emergency departments worldwide to manage patient flow safely

when clinical needs exceed capacity. It promulgates a system Inhibitors,research,lifescience,medical that delivers a teachable, auditable method of assigning clinical priority in emergency settings [17]. In contemporary emergency care, triage is regarded as an essential function not only during massive influx of patients as in disasters, epidemics and pandemics but also in regular emergency care departments. The burden in emergency care is increasing and so are the expectations of patients [1]. In hospitals that apply triage for regular emergency care, triage is the first point of contact with Inhibitors,research,lifescience,medical the ED. Assessment by the triage officers involves a combination of the chief complaint of the patient, general appearance and at times, recording of vital signs [25]. Guidelines for Emergency Department Triage Triage guidelines score emergency patients into several categories and relate it to the maximum Inhibitors,research,lifescience,medical waiting time based on specific criteria of clinical urgency. Initial versions of triage guidelines had three levels of categorization mostly

termed as emergent, urgent and non-urgent [25]. Studies have revealed that five-level triage systems are more effective, valid and reliable [25,26]. In contemporary emergency care, most triage systems sort out patients into five categories or levels (Table ​(Table1)1) including Inhibitors,research,lifescience,medical the time within which the patient should be seen by the emergency care provider [27]. Table 1 Five-level Triage TCL Systems The most commonly used guidelines for ED triage on the international literature are The Manchester Triage Score [17,28,29], The Canadian Triage and Acuity Scale [28-31], The Australasian Triage Scale [28,32] and Emergency severity Index [27,29]. In ESI, there are five-levels of these triage score (see Figure ​Figure1).1). In addition national and institutional guidelines are also developed and used in practice [15,33]. Figure 1 Emergency Severity Index (ESI) Triage Algorithm, v. 4 (Five Levels). When reflecting on the question whether these triage systems say anything about how to sort a patient among one of the five levels, we can apply The Manchester Triage Score [17] as an example.

One problem is, however, that the current phenotypes might be inadequate.128 It is highly unlikely that the new DSM-V classification of PDs will provide a solution. A strategy that has been proposed to increase the rate of success for molecular genetics in psychiatry is the use of endophenotypes, defined as a heritable characteristic that is along the pathway between a disorder and genotype.5 Although the strategy has not yet proven to be successful,133 it has been suggested that this approach should be applied to the study of PDs

by using clinical dimensions like for example affective instability, impulsivity, and aggression instead of diagnoses.134
Major Depressive Disorder (MDD) is Inhibitors,research,lifescience,medical common, costly,1-3 and notably heterogeneous. Unfortunately, the accurate prediction

and subsequent prevention of MDD episodes (MDEs) has been challenging. There is evidence that MDEs are variously associated Inhibitors,research,lifescience,medical with elevated psychosocial stress, the postpartum period, hypothyroidism, circadian changes, cerebrovascular disease, administration of inflammatory cytokines Inhibitors,research,lifescience,medical such as interferon-α (IFN-α), etc. check details Therefore, one approach for preventing a MDE could be to avoid stressful circumstances, pregnancy, cerebrovascular disease, and/or IFN-α therapy. However, this is often impractical. Thankfully, most people who are exposed to these various“triggers” do not develop MDD. Identifying modifiable markers of risk in specificallyvulnerable people, and then mitigating these before MDD occurs, could be a better approach for preventing MDD. However, identifying causal risk factors that Inhibitors,research,lifescience,medical pre-exist in nondepressed people requires prospective studies, and the incidence of an MDE over 1 year is less than 2%.4-6 The necessarily large epidemiologic studies have successfully identified predictive risk markers such as gender, age, cohort, family history, marital status, socioeconomic status, and stressful life events6,7 – but each of these is difficult or impossible Inhibitors,research,lifescience,medical to mitigate. Another strategy is needed for prospectively assessing nondepressed people for modifiable

Ergoloid risk factors, and a related strategy is needed for examining whether specifically alleviating these vulnerabilities prevents MDE. MDD during IFN-α therapy One approach for delineating modifiable risk factors is to examine homogeneous groups of people who are definitively known to soon be exposed to a specific MDD-evoking situation. Towards this end, patients receiving IFN-α may be ideal candidates for examining MDD vulnerability.8-12 MDD during IFN-α treatment (IFN-MDD) typically develops within the first 2 or 3 months of administration,13-17 and occurs in about 15% to 40% of patients.18 Thus, prospectively assessing IFN-MDD onset is feasible – and consequently it may be possible to determine predictive modifiable vulnerabilities in the 15% to 40% who subsequently develop IFN-MDD.
