6 and 1.2mmol/liter [BNF, 1988]. In 2004 the Quality and Outcomes Framework (QOF) was initiated as part of the General Medical Services Contract. The QOF is a voluntary http://www.selleckchem.com/products/17-DMAG,Hydrochloride-Salt.html incentive scheme for primary care. It contains groups of indicators against which practices are scored according to their level of achievement [The Information Centre for Health and Social Care, 2012]. Within the QOF section on mental health, practices are scored for the percentage of patients on lithium with a record of serum creatinine and thyroid stimulating hormone (TSH) within the preceding 9 months, a record of lithium levels in the therapeutic range within the previous 4 months

and a Inhibitors,research,lifescience,medical body mass index (BMI) recorded in the past 15 months [The Information Centre for Health and Social Care, 2012]. NICE bipolar guidance states Inhibitors,research,lifescience,medical that, during maintenance treatment with lithium, a serum lithium level should be taken every 3 months, renal and thyroid function tests should be completed every 6 months (more often if there is evidence of impaired renal function), Inhibitors,research,lifescience,medical and weight, BMI or waist circumference should be measured annually [NICE, 2006]. The BAP guideline recommends that renal and thyroid function are tested every 12 months, with lithium levels checked every 3–6 months in people on a stable dose [BAP, 2009]. In December 2009 the National

Patient Safety Agency (NPSA) released a patient safety alert to improve the safety of lithium therapy [NPSA, 2009]. This focused on regular monitoring in line with NICE guidance; reliable communication systems for blood test results; appropriate verbal and written Inhibitors,research,lifescience,medical information provided to patients and systems are in place to identify and deal with potential interactions with lithium therapy [NPSA, 2009]. Lithium management in Norfolk Following a series of clinical incidents in primary care regarding lithium toxicity, concerns were raised at Norwich Primary Care Trust that there was not a consistent Inhibitors,research,lifescience,medical approach to lithium monitoring across Norfolk. Data were extracted from the Norfolk and Norwich University Hospital pathology system from

October 1999 to October 2000. From a total of 1457 people with lithium levels recorded within this year, 32.6% had only one level, 54.3% had one or two levels, 45.6% had three or more levels, and 29.4% had four or more too levels [Holmes, 2005]. By May 2000 a pharmacy-led prescribing group had conceived the idea of a Norfolk-wide lithium register and database to help minimize the potential for future clinical incidents relating to lithium prescribing and monitoring. The lithium database was first implemented in May 2002 and complete rollout across Norfolk occurred by 2004 [Holmes, 2005]. For the successful implementation of this database there were two issues surrounding lithium prescribing and monitoring which needed to be addressed.

Isolated pulmonary valve stenosis (PS) makes up 6-9% of all conge

Isolated pulmonary valve stenosis (PS) makes up 6-9% of all congenital heart defects among children. PS is divided into valvar, subvalvar, supravalvar, according to the anatomically stenotic portion, and valvar PS is known to be the most common type. The type of stenosis may be the deciding point for the method of therapy, surgical or interventional, and its effects.1) PS can be divided into mild,

moderate, and severe according to Inhibitors,research,lifescience,medical the Vorinostat supplier Pressure gradient between the systemic pressure and the right ventricle systolic pressure (RVSP): mild to moderate (RVSP ≤ 75% of systemic pressure); severe (RVSP 76-100% of systemic pressure); critical (RVSP > 100%). In the past, these patients were candidates Inhibitors,research,lifescience,medical of surgical valvotomy, but in moderate to severe PS, percutaneous balloon pulmonary valvuloplasty (BPV) has risen as the first treatment option since the first introduction in 1982.2) Since the initial adoption of the procedure, equipment for BPV has improved and the skills of the performers have ameliorated, leading to minimal complications and its usefulness, proven in many previous studies.3-5)

The initial gold standard for diagnosis of PS is by echocardiography. In 2-dimensional (2D) echocardiography there can be evidence of right ventricle (RV) hypertrophy, RV enlargement, or right atrial enlargement. Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical Color flow Doppler imaging demonstrates high-velocity turbulent systolic flow through the pulmonary valve.6) Pressure gradients can simultaneously be estimated by continuous wave Doppler.7) Pressure gradients consist of echocardiographic systolic pressure gradient and mean pressure gradient. In case of aortic valve stenosis which is similar obstruction Inhibitors,research,lifescience,medical disease, mean pressure gradient is considered more important for evaluation of disease among those two gradients.8) However, the most accurate diagnosis still remains to be measurement of the pressure gradient through transcatheterization. The purpose of this study is to compare the difference between the echocardiographic data to

the cardiac catheterization data on the diagnosis, treatment, and follow-up in patients found diagnosed as PS, and to see what parameters should be closely monitored. Methods Subjects A total of 112 patients (Male : Female = 46 : 66) who underwent BPV at Severance Cardiovascular Hospital, between December, 2002 to August, 2012 were retrospectively analyzed. The patients were all under 16 years of age and critical PS patients who underwent BPV were excluded from this study. The age range was between 1 month to 192 months and mean age 38.35 months (± 48.55 months). Patients with concomitant simple observable heart diseases such as atrial septal defect or patent foramen ovale were included, but those with complex heart diseases were excluded.

Although still speculative in some aspects, sensitization and kin

Although still speculative in some aspects, sensitization and kindling as described by Post et al74 may be helpful in understanding the course of BD, starting from a molecular level and evolving towards behavioral changes. Kraepelin75 had already noticed in 1921 that a marked psychosocial stressor usually preceded the first affective episode, GDC-0068 clinical trial whereas subsequent episodes showed minor or even absent

Inhibitors,research,lifescience,medical notable life events. At the same time, the frequency of episodes tends to increase, in some patients to the point of autonomous rapid cycling, with decreasing efficacy of mood-stabilizing drugs. Post and Contel76 developed the model of cocaine-induced behavioral sensitization (CIBS). Cocaine administration causes hypcrlocomotion in rats and hypomanic-likc Inhibitors,research,lifescience,medical symptoms

in man. Repeated cocaine administration, however, may cause a shift of symptomatology toward signs of dysphoric mania (which has a high incidence in BD, as shown by the EPIMAN study) or even paranoid symptoms. Lcsioning experiments in the amygdala show that CIBS involves different neuromodulatory changes depending on the duration and frequency of cocaine administration. Thus, not only the symptomatology can shift, but also the neuronal Inhibitors,research,lifescience,medical pathways involved, becoming independent of a direct action on the amygdala. Furthermore, cocaine is also capable of influencing neuromodulators in a similar fashion to stress, Inhibitors,research,lifescience,medical ie, by causing an increase in CRF, ACl’H, Cortisol, cytokines, catecholamines, and indolamines. Relating these findings to intracellular transcriptional processes, another important analogy to stress sensitization can be noted. Both conditions, CIBS and repeated stress, lead at the end of the intracellular signal-transducing cascade to the expression of immediate early genes (c-fos and zif -268) in the amygdala and Inhibitors,research,lifescience,medical related limbic structures as well as late effector genes (LEG).77 The composition of early genes and their occupation of the activator protein- 1 (AP-1) receptor is partially specific for different stressors, eg, electroconvulsive seizures or cocaine, as well as

for mode of application, ie, acute, repetitive or chronic.78, 79 This may provide a molecular background for speculation as to why psychosocial much stressors may be more likely to cause symptoms of depression, whereas others, like acute pain, do not. Whereas activation of early immediate genes primarily induces expression of genes, such as neurotransmitter transporter genes, and finally modulates the acute symptomatology, induction of LEGs such as neurotropins and nerve growth factor (NGF) will modulate synaptic connectivity and nerve end sprouting, thereby giving rise to neuroanatomical changes. Taken together, CIBS is a useful model to study acute events and long-term changes in symptomatology caused by episodes of affective disorders.

1994) and the semiautomatic P3a components, whereas no difference should be found on the P3b component given that the sounds were task irrelevant

(Knight and Scabini 1998; Polich and Criado 2006; Polich 2007). One explanation for these unexpected findings is that the novel sounds resemble familiar ones, as around 80% (35 of 45) of the sounds were either animal or vehicle related, or sounds made by a human voice. However, other studies have found a novelty N2 and P3a using similar sounds (e.g., Kihara et al. 2010). Another this website possibility is that the spacing of the sequence of sounds worked against the establishment of the context required for oddball effects: auditory oddball paradigms normally have much shorter interstimulus Inhibitors,research,lifescience,medical intervals (Nyman et al.

1990; Kujala Inhibitors,research,lifescience,medical et al. 2001; Kihara et al. 2010). Nevertheless, the novel sounds did attract attention of the participants, as indicated by increased P3b amplitudes for novel as compared to standard sounds. A final option is that the complexity difference between the standard “beep” and the novel sounds masked a novelty effect. However, this is not supported by other studies in the field. Ceponiene and his group have found that the differences in Inhibitors,research,lifescience,medical the amplitude of the N2 component are opposite to our results, with complex sounds eliciting larger amplitudes than simpler ones (e.g., Ceponiene et al. 2001). In our study, we also found latency differences between complex and simple sounds, with complex sounds having a later latency. Again,

Inhibitors,research,lifescience,medical this was not found in previous studies. The evidence concerning this matter comes mainly from developmental studies, which have not found any difference in the latency of the N2 component between complex and simple sounds (Ceponiene et al. 2005). While novel sounds thus attracted attention, words presented with those sounds were recalled Inhibitors,research,lifescience,medical less often than words presented with standard sounds. This was true when the sound came during word presentation (Experiment 1), but not if the sound was played before the word (Experiment 2). This suggests that novelty was not aiding encoding; instead, Oxymatrine novel sounds attracted attention away from the words when they co-occurred as in Experiment 1, yielding worse memory. The critical test for the hypothesis that novelty aids encoding is whether we would find a higher N2b–P3a complex for correctly recalled items. In fact, only a main effect was found for the accuracy in the N2b component, but no interaction was found between accuracy and novelty. This indicates that the N2b at acquisition indexes some process that aids later recall. However, this is not novelty processing, as this process is not differentially expressed for novel than for standard-font trials. With respect to the P3a, no difference in amplitude was found between subsequently recalled and not-recalled words. This suggests that the novelty processing indexed by the N2b–P3a is not beneficial for recall.

Murine orthotopic models, utilising female athymic nude mice, wer

Murine orthotopic models, utilising female PTC124 mw athymic nude mice, were injected with SKOV3Trip2 taxane-resistant ovarian cancer cell line and consequently,

following one week, subjected to anti-Jagged1 siRNA/chitosan nanoparticle complexes (5μg dose of siRNA) with/without taxane, applied via intraperitoneal route twice weekly for a total period Inhibitors,research,lifescience,medical of five weeks [99]. The results of this study indicated that such nanoparticle-based complexes had the capacity to reduce tumour weight by over 70% within such murine models and also induced taxane sensitization within the tumour [99]. In a similar study, cationic liposome-polycation-DNA (LPD) and anionic liposome-polycation-DNA (LPD II) nanoparticle systems were developed to incorporate doxorubicin and VEGF siRNA within a murine ovarian cancer animal model [111]. Female, athymic nude Inhibitors,research,lifescience,medical mice were treated with 5 × 106

cells of the MDR ovarian cancer cell line NCI/ADR-RES [111]. Once the murine tumours reached a size of approximately 16–25mm2, the mice were consequently injected with individual nanoparticle complexes bearing either siRNA or doxorubicin at a dose of 1.2mg/Kg in both cases, once daily for three consecutive days [111]. The results of this study demonstrated the effectiveness of such nanoparticle complexes for inhibiting tumour progression Inhibitors,research,lifescience,medical within the treated murine model groups, mainly due to impaired VEGF expression-related MDR [111]. Other human cancer conditions which Inhibitors,research,lifescience,medical were investigated for circumvention of tumour MDR properties through

nanoparticle delivery include uterine sarcomas [112]. In the study carried out by Huang et al. [112], pH-sensitive mesoporous silica nanoparticles incorporating hydrazine and doxorubicin were developed for in vivo testing on murine models of doxorubicin-resistant uterine sarcoma. Since the composition Inhibitors,research,lifescience,medical of such nanoparticles specifically allow for cellular uptake through endocytosis, bypassing of the P-gp efflux pump induced a marked reduction in P-gp dependent MDR properties [112]. Consequently, the murine MDR tumour model treated with such nanoparticles demonstrated enhanced tumour apoptotic effects which were clearly confirmed by active caspase-3 immunohistochemical validation analysis [112]. 6. Conclusion The latest studies described above undoubtedly serve as a testament to the immense clinical value represented by nanoparticle technology. The ability of such nanoparticles, Resminostat irrelevant of biomaterial composition to efficiently load individual or combinations of chemotherapeutic drugs and/or chemosensitising agents (such as curcumin) and novel RNA interference-based therapies has been clearly demonstrated above. This property provides an excellent escape mechanism for circumventing target tumour cell multidrug resistance properties based on drug efflux pump activity on the tumour cell surface, such as that exerted by P-gp.

21 intracellular adhesion molecule (ICAM)-l is a type-1 related

21 intracellular adhesion molecule (ICAM)-l is a type-1 related protein and a celladhesion molecule expressed on macrophages and lymphocytes. Decreased

Selleckchem ATM Kinase Inhibitor levels of the soluble (s) intercellular adhesion molecule-1 (ICAM-1), as found in schizophrenia, also represent an underactivation of the type-1 immune system.22 Decreased levels of the soluble TNFreceptor p55 – mostly Inhibitors,research,lifescience,medical decreased when TNF-α is decreased – were observed, too.23 A blunted response of the skin to different antigens in schizophrenia was observed before the era of antipsychotics.24 This finding could be replicated in unmedicated schizophrenic patients using a skin test for the Inhibitors,research,lifescience,medical cellular immune response.25 However, there are some conflicting results regarding increased levels of Thl cytokines in schizophrenia.26 The latest meta-analysis showed dominant proinflammatory changes in schizophrenia but not involving Th2 cytokines.27 After including antipsychotic medication effects into the Inhibitors,research,lifescience,medical analysis, only increases of IL1 receptor antagonist serum levels and of IL-6 serum levels were found. Type-1 parameters, hypothesized to be downregulated in schizophrenia, were not included in the meta-analysis,

Inhibitors,research,lifescience,medical because only a few studies have been performed in unmedicated patients. Several reports described increased serum IL-6 levels in schizophrenia.28 IL-6 serum levels might

be especially high in patients with an unfavorable course of the Inhibitors,research,lifescience,medical disease.29 IL-6 is a product of activated monocytes, and some authors refer to it as a marker of the type-2 immune response. Moreover, several other signs of activation of the type-2 immune response are described in schizophrenia, including increased Th2 type of lymphocytes in the blood,30 increased production of immunoglobuiinE (IgE), and an increase in IL-10 serum levels.31,32 In the CSF, IL-10 levels were found to be related to the severity of the psychosis.32 The key cytokine of the type-2 immune response is IL4. Increased levels of IL-4 in the CSF of juvenile schizophrenic patients through have been reported,33 which indicates that the increased type-2 response in schizophrenia is not only a phenomenon of the peripheral immune response. However, the data show that the immune response in schizophrenia can be confounded partly by factors specific to the disease such as its duration, chronicity, or therapy response, and partly by other factors such as antipsychotic medication, smoking, etc.

Results: In both groups, pain decrement at the mentioned time points was significant (P<0.001), but had no significant difference (P>0.05), indicating the similar effect of both drugs on pain improvement. In the SV group, photophobia, phonophobia, nausea, and vomiting were improved significantly, while in the Sumatriptan group, only photophobia and vomiting were decreased significantly, indicating the advantage of SV in improving

Inhibitors,research,lifescience,medical the associated symptoms. Nausea, vomiting, facial paresthesia, and hypotension were more significantly frequent in the Sumatriptan group than in the SV group (P<0.05). Conclusion: Intravenous SV (400 mg) was as effective as subcutaneous Sumatriptan in the treatment of acute migraine attacks, but with more improvement in associated symptoms and with fewer side effects. Trial Registration Number: IRCT201108025943N4 Keywords: Migraine, Sodium valproate, Sumatriptan Introduction Migraine commonly presents as a unilateral (60%), pulsatile (85%) headache which is usually associated with nausea (90%), vomiting (30%), photophobia Inhibitors,research,lifescience,medical and phonophobia (80%), and fatigue.1 Age shows a bimodal distribution in men and women, peaking in the late teens and 20s and around 50 years of age.2 The male-to-female ratio is 1/1 before puberty and 1/3 after puberty.3 The comorbidities of migraine are psychiatric (depression), neurological Inhibitors,research,lifescience,medical (narcolepsy),

cardiovascular (patent foramen ovale), and others (fibromyalgia). Also, migraine has been known as a risk factor for other diseases such as panic attack, asthma, myocardial infarction, and depression.4 Migraine has two forms: classic (with aura) and common (without aura). The pathogenesis of aura and migraine headache is intracranial vasoconstriction and extracranial vasodilatation, respectively.1 Recent Inhibitors,research,lifescience,medical studies have revealed that

focal cerebral Inhibitors,research,lifescience,medical 3-MA in vivo ischemia occurs during migraine attacks. Vascular changes in migraine are secondary to primary dysfunction in the brain stem neurons.1 The predisposing factors for migraine attacks include  neck muscle pain, alcohol or coffee consumption, smoking, chronic stress, physical inactivity, hormonal changes, being female, low socioeconomic status and educational level, depression, sleep disturbance, obesity, diet (tyramine, monosodium glutamate, chocolate, nuts, and dried fruits), Oxygenase sudden changes in weather, hot and humid climates, bright light, and consumption of painkillers, oral contraceptive pills, or drugs such as dipyridamole and Trinitroglycerin.1,5-9 The treatment depends on whether migraine is acute or chronic. Patients with headaches lasting for more than 4 days per month may need prophylactic drugs.10 Nowadays, the most prevalent prophylactic drugs are Propranolol, sodium valproate, Topiramate, Amitriptyline, Verapamil, Gabapentin, Cyproheptadine, and Pizotifen.11-14 Acupuncture, relaxation therapy, biofeedback, and cognitive behavioral therapy also may have some benefits.

Cardiac side effects can be divided into acute and late-onset eve

Cardiac side effects can be divided into acute and late-onset events. Acute toxicity encompasses phenomena that are usually reversible

and nonfatal, such as hypotension, tachycardia, and arrhythmias. The PR-171 occurrence of symptoms of myocarditis (with or without accompanying pericarditis) in the immediate posttreatment days is less frequent but can lead to heart failure that is usually reversible. However, late-onset cardiotoxicity is the Inhibitors,research,lifescience,medical most relevant problem. It results in dilated cardiomyopathy that causes lethal congestive heart failure (CHF) in 75% of cases in the following 5 years and whose end-stage treatment may require a heart transplant [23]. This type of heart disease responds to a dosing and regimen-dependent pattern [22]. Toxicity is higher when anthracyclines are administered in bolus compared to regimens giving it as a continuous infusion and this seems to be related to the higher dose peak reached when administered in a short period of time. A number of factors that predispose to this toxicity have been identified. Specifically, they are hypertension,

Inhibitors,research,lifescience,medical age below 15 or over 70 years, Inhibitors,research,lifescience,medical a history of radiotherapy to the mediastinum, and the concomitant use with other drugs such as cyclophosphamide, paclitaxel, or trastuzumab. In particular, when given with paclitaxel the risk of cardiotoxicity is higher when doxorubicin is administered just after paclitaxel instead of the opposite sequence. The earlier studies only recognized clinical-evident cardiac toxicity. 3-4% of patients treated with cumulative doses of 450mg/m2 and up to 18% of those who received 700mg/m2 presented with clinical heart failure [24]. The incidence of heart failure is lesser when epirubicin was Inhibitors,research,lifescience,medical used but occurred in a 0.7% of patients when cumulative doses of 660mg/m2 were reached [25]. Anthracyclines cause some pathological changes prior to the occurrence of clinical cardiomyopathy that can be detected by different techniques: myocardial biopsy (Billingham scale); isotope ventriculography (MUGA scan) and echocardiography. Billingham published in 1978

Inhibitors,research,lifescience,medical a histological classification based on the findings observed in myocardial biopsies. Biopsy findings correlated fairly well with the cumulative doses of anthracyclines and were able to detect early damage to the myocardial cells. Early histological changes secondary to anthracyclines Endonuclease include cytoplasmic vacuolization and loss of muscle fibres from myocytes due to dilated sarcoplasmic reticulum. In more advanced stages, changes occur in cellular remodelling leading to left ventricular failure [26]. Such an invasive method has had no widespread use in daily clinical practice. Isotope ventriculography (MUGA scan) has proven to be an easily reproducible and accurate technique in detecting anthracycline-induced cardiotoxicity [27]. Echocardiography is another noninvasive test used in the study and followup of anthracycline-induced cardiotoxicity.

Case report A 75-year-old woman was admitted to a tertiary psych

Case report A 75-year-old woman was admitted to a tertiary psychiatric facility in Sri Lanka in February 2012 with a 1-week history of increased speech and activity and poor sleep suggestive of a manic episode. She had been diagnosed as having see more bipolar affective disorder from her late teens and had been treated with several antipsychotics, both typical and atypical, in addition to mood stabilizers during past relapses and as maintenance. She was noncompliant with treatment 6 months Inhibitors,research,lifescience,medical prior to the current admission. The corroborative

history from her family members revealed that her treatment adherence was generally poor resulting in relapses approximately once in every 3 years. Most of these were manic Inhibitors,research,lifescience,medical episodes and according to the medical records she had been hospitalized for inpatient treatment nearly ten times in the past. However, in between the episodes she had

been functioning relatively well. According to her personal history her husband passed away 10 years ago and she had five grown-up children who provided her with good care and support. She had a strong family history of mental illness as one of her sisters was diagnosed as having bipolar affective disorder and was on medication. She did not have any significant medical history or history of psychoactive Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical substance use in the past. Her mental state examination on admission revealed her mood was elated and she did not have any psychotic features. She was well oriented but had poor insight regarding her mental state. Her vital functions were normal. She had to be sedated with 5 mg of intramuscular haloperidol on admission as she was disturbed and she failed to

calm down with oral sedative drugs. Her medication history revealed that she had been well stabilized with risperidone 4 mg twice daily and sodium valproate Inhibitors,research,lifescience,medical 400 mg twice daily for about 3 years prior to her reducing the medications on her own by halving the doses of both medications (risperidone 4 mg once daily and sodium valproate 200 mg twice either daily) during the last 6 months. She was recommenced with the previous dose of psychotropic medications of risperidone 4 mg twice daily and sodium valproate 400 mg twice daily on admission and she needed occasional sedation with oral lorazepam 1 mg for her agitated behavior and poor sleep. With time (a day after the admission) she developed slurred speech due to extrapyramidal side effects and subsequently benzhexol 4 mg daily was added and risperidone dose was reduced to 4 mg at night. Her extrapyramidal symptoms resolved with the above dose adjustment of the psychotropic medications on the third day after admission. As she developed drowsiness (4 days after admission), lorazepam was omitted.

72 Robins and Guze74 proposed several

formal criteria for establishing the validity of psychiatric diagnoses: (i) clinical description; (ii) laboratory studies; (iii) delimitation from other disorders; (iv) follow-up learn more studies (including evidence of diagnostic stability); and (v) family studies. This schema was elaborated by Kendler75 who distinguished between antecedent validators (familial aggregation, premorbid personality and precipitating factors); concurrent validators (including psychological tests); and Inhibitors,research,lifescience,medical predictive validators (diagnostic consistency over time, rates of relapse and recovery, and response to treatment). Andreasen76 has proposed “a second structural program for validating psychiatric diagnosis” and listed several additional validators-molecular genetics and molecular Inhibitors,research,lifescience,medical biology, neurochemistry, neuroanatomy, neurophysiology and cognitive neuroscience – all potentially capable of linking symptoms

and diagnoses to their neural substrates. The Inhibitors,research,lifescience,medical problem with both Robins and Guze’s and Kendler’s validity criteria is that they implicitly assumed that psychiatric disorders were discrete entities. The possibility that disorders might merge into one another with no natural boundary (or “point of rarity•)77 was not considered. Robins and Guze’s classical paper was written at a time when it was assumed that schizophrenia and bipolar disorder were transmitted by a single, or at the most by a small number of genes. The present situation is different. It is now Inhibitors,research,lifescience,medical almost generally accepted that many different genes and gene networks contribute to the etiology of most of psychiatry’s major syndromes, including schizophrenia, and that combinations of such genes are risk factors for what have until now been regarded as

unrelated syndromes. For example, the Inhibitors,research,lifescience,medical microdeletion in chromosome 22q11 which underlies the velocardiofacial syndrome is associated with a raised incidence of intellectual disability, schizophrenia, and bipolar affective disorder.78,79 The genetic basis of schizophrenia Megestrol Acetate is likely to encompass a spectrum of other disorders, including schizotypal personality disorder and, possibly, bipolar disorder with psychotic symptoms.2 It will not be surprising if such findings of overlapping genetic predisposition to seemingly unrelated disorders become soon the rule rather than the exception. Against this background, a recent review of the evidence for assessing schizophrenia and related psychotic disorders against a range of “validating criteria” proposed by the DSM-V Task Force Study Group80 is worth highlighting.
