AChRs are concentrated at the peaks of abundant, well-preserved and intricately twisted junctional folds. B and C: NMJ in EAMG induced by MuSK antibodies, CMS with … Resemblance of clinical features between MuSK MG and CMS with Dok-7 mutations Recently a MuSK-interacting protein called Dok-7 was discovered (25) and Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical identified as a member of the Dok family of cytoplasmic proteins. Dok-7 is postulated to have

three main functional domains: a pleckstrin homology (PH) domain, essential for membrane association; a phosphotyrosine-binding (PTB) domain involved in the Dok-7 induced activation of MuSK; and a large C-terminal Inhibitors,research,lifescience,medical domain containing multiple tyrosine residues. Dok-7 knock-out mice showed marked disruption of neuromuscular synaptogenesis that was indistinguishable from the features found in MuSK-deficient mice. Thus, Dok-7 is essential for neuromuscular synaptogenesis through its interaction with MuSK. Mutations in the Dok-7 protein cause a genetic form of limb-girdle myasthenia (also classed as CMS) (26). Some clinical features in these patients resemble those in the severe type of MG accompanied by MuSK antibodies (27). Proximal muscles are usually more affected than those in Inhibitors,research,lifescience,medical distal regions, as evident in MuSK MG patients, and ptosis is often present. Limb-muscle weakness is comparatively less severe. Previous studies showed no reduction of AChR clustering with significant changes in NMJ of MuSK MG patients (20),

but further structural analysis of NMJ is required Inhibitors,research,lifescience,medical in muscles where severe weakness occurs commonly. The weakness and atrophy are not observed uniformly in muscles of these patients, although both MuSK and Dok-7 are essential for the formation of NMJ during the embryonic stage Sclareol (25). Of course, one of the major distinctions between acquired MuSK MG and CMS with the Dok-7 mutation is the timing when weakness begins. The CMS patients typically have difficulty in walking after reaching that normal motor milestone during early childhood, whereas the onset of weakness for MG patients, in most instances, occurs in adulthood. Interestingly, AChR clustering and post-synaptic folds are reduced with small motor terminals as observed at NMJ in CMS with Dok-7 mutations. AChR clustering and post-synaptic folds are reduced with small motor terminals as observed at NMJ in CMS with Dok-7 mutations (28).

3: recovery, Table 3). However, neither the delay in onset to recovery nor its voltage and temperature dependence were altered by R1448H. Table 2. Time constants of entry into fast inactivation. Table 3. Time constants of recovery from fast inactivation. Gating model The gating model used in the present study consisted

of a series of four closed states C1-C4, one open state O and four inactivated Inhibitors,research,lifescience,medical states I1-I3 and IT (Fig. 4). By convention, all transitions towards O have positive valences because they are favored by depolarization, while those away from O have negative valences because they are favored by repolarization. Rate constants between the closed states and rate constants between C3-C4-O and I1-I2-I3 were assumed to be equal to reduce

the number of free parameters. The model is based on previous models of Vandenberg and Bezanilla (19). However, to properly describe gating Inhibitors,research,lifescience,medical of WT and R1448H and their temperature dependence, two modifications were made. First, we introduced a transient inactivated state IT as previously suggested by Kahlig et al. (10) to account for the biphasic inactivation especially at low temperatures. Second, we introduced a transition between C4 and I2. This transition was essential to reproduce inactivation from closed states especially in the voltage range around threshold of Na+ channels. Figure 4. Gating model. Gating model used Inhibitors,research,lifescience,medical for kinetic simulations, consists of 4 closed-states C1–C4, one open- state O, four inactivated-states I1–I3 and IT. Arrows between states indicate possible transitions and _i and _i (i=1..6) represent the … The model was able to reproduce Inhibitors,research,lifescience,medical all measurements including the strong voltage dependence of channel activation, open and closed state inactivation, recovery and temperature dependence (Fig. 5). The model resulted in rate constants of WT and R1448H which were similar for

Inhibitors,research,lifescience,medical most transitions (Tables 4 and ​and5).5). However the rate constants alpha3, beta3 and alpha6 markedly differed between WT and R1448H. The smaller alpha6 explains the impaired fast inactivation of R1448H. The most striking difference between WT and mutant related to alpha3 and beta3, the transition between C4 and I2. In contrast isothipendyl to the WT for which the calculated rate constants suggest that this transition does not occur, the mutant performed this closed-state inactivation transition with a high likelihood. Table 4. Model parameters for WT. Table 5. Model parameters for R1448H. Figure 5. Representative current traces and fits.

For example the equivalent gating charge for opening the channels from rest was 5.31 to 6.78 e0 for WT and 4.39 to 5.

The increased binding ability among these Z-band components cause

The increased binding ability among these Z-band components caused by the HCM-associated

mutations might increase the stiffness of sarcomere structure and increase the passive tension in cardiomyocytes. Because the stiff sarcomere might lead to diastolic dysfunction in muscle contractility, the molecular mechanism of the Z-band HCM could be linked to that in the sarcomere HCM, i.e., increased Ca2+-sensitivity of muscle contraction. On the other hand, other HCM-associated mutations, TTN Ser3799Tyr and OBSCN Arg4344Gln, altered binding to FHL2 and titin/connectin, respectively (14, 15). Because FHL2 and obscurin are localized around the Z- to I-band and mediate intracellular Inhibitors,research,lifescience,medical signaling molecules (16, 17), the altered binding of obscurin and FHL2 to titin/connectin might lead to dysfunction of signaling pathways. Dilated cardiomyopathy Dilated Inhibitors,research,lifescience,medical cardiomyopathy (DCM) is a cardiac disease characterized by cardiac enlargement associated with systolic dysfunction and often manifests with congestive heart failure (7). Although the majority of DCM patients are sporadic cases, apparent family histories, Inhibitors,research,lifescience,medical consistent with autosomal dominant inheritance,

can be found in 20-35% of patients, suggesting that genetic abnormalities cause DCM in some of the patients (18). There have been many reports on the genetic etiologies of DCM (Table ​(Table1),1), which may be classified into at least 5 groups: abnormalities in the components for cytoskeletal proteins of cardiomyocytes, such as mutations in genes for desmin (DES), dystrophin (DMD), δ-sarcoglycan (SAGD), metavinculin (VCL), α-actinin (ACTN2), titin/connectin Inhibitors,research,lifescience,medical (TTN), MLP (CSRP3), T-cap/telethonin (TCAP) and Cypher/ZASP (LDB3); mutations in the genes for sarcomeric proteins of the heart, such as cardiac β-myosin heavy chain (MYH7), Inhibitors,research,lifescience,medical cardiac

α-myosin heavy chain (MYH6), α-cardiac actin (ACTC), myosin binding protein-C (MYBPC3), cardiac troponin I (TNNI3), cardiac troponin C (TNNC1), cardiac troponin T (TNNT2) and α-tropomyosin (TPM1); defects in the component of nuclear envelope, which may participate in signal Sitaxentan transduction between the cytoplasm and the nucleus, such as mutations in the gene for lamin A/C (LMNA); mutations affecting supply and/or regulation of energy metabolism, such as CPTase II (CPT2) deficiency and mutations in tafazzin (TAZ) and ATP-sensitive K channel (ABCC9); cardiac ion channel mutations (Table ​(Table1).1). In STI571 nmr addition, a mutation in a transcriptional co-activator gene (EYA4) was recently reported to cause DCM accompanied by hearing loss (19). Among these genetic causes, the majority can be classified into cytoarchitectural abnormalities (20). In addition, it is now widely accepted that DCM and HCM are allelic disorders due to the mutations in genes for sarcomere/Z-band components, MYH7, MYH6, TNNT2, TPM1, MYBPC, TNNI3, TNNC1, ACTC, TTN, CSRP3, TCAP, LDB3, ACTN2 and VCL.

Individuals at risk of influenza related complications include th

Individuals at risk of influenza related complications include those with

chronic respiratory, heart, liver or kidney disease, and the immunosuppressed, as well as all individuals over the age of 64 years [10]. Although at risk individuals are selleckchem currently targeted for seasonal vaccination in England and Wales and a number of other European countries, vaccination rates in most countries are suboptimal although coverage of the elderly is often better than that of clinical risk groups [11] and [12]. A recent survey has shown that vaccination rates in the elderly differ considerably across Europe [12], being highest in the UK (70.2%) and lowest in Eastern European countries such as Poland (13.9%). Furthermore, evidence is accumulating that vaccination of the elderly with an inactivated vaccine offers only partial protection. Reported estimates of vaccine effectiveness vary widely in the elderly, ranging from 20% to over 50% [13] and [14]. Vaccination rates in individuals with a chronic medical Selleck Pexidartinib condition considered at a high risk

of developing complications due to influenza are also low, ranging from 56% in the UK to 11% in Poland. Vaccination rates have increased marginally over the last few years. Non-vaccinated individuals constitute a hard to reach group. In those EU member states where vaccination rates are low due to the absence of funding, childhood vaccination may be an attractive option. Provided adequate coverage is achieved, not only will children be protected but herd immunity could offer protection to at risk groups across the age ranges. The aim of this paper is to estimate the

potential clinical impact of paediatric influenza vaccination in England and Wales. Specific objectives were to develop a demographic model of England and Wales, to capture the inhibitors population structure over time, and to create a dynamic transmission model simulating the transmission of influenza and the current influenza vaccination policy. A set of risk functions were developed to translate the Linifanib (ABT-869) incidence of infection into clinical outcomes. The resulting model was used to estimate the impact of vaccinating pre-school and school aged children with a live attenuated influenza vaccine. Clinical impact was quantified as the mean annual number of averted influenza infections and the related general practice consultations, hospitalisations and deaths, over a 15-year time horizon. The model adopts a realistic age structure (RAS), starting with population data for England and Wales in 1980, provided by the Office for National Statistics (ONS). These data are single year of age stratified population numbers [15].

However, given the time burden of GPs and the numbers of patients

However, given the time burden of GPs and the numbers of patients with mental disorders, the search for clinically meaningful typologies of patients

according to their profile of mental disorders might be the most important target for the future. This is particularly true if we consider that it is unlikely that simplified classifications of mental disorders for use in primary care Inhibitors,research,lifescience,medical will become available in the immediate future. Recognition If unselected patients are diagnosed independently, using appropriate diagnostic instruments for a given mental disorder, almost all studies- irrespective of the type of diagnosis considered- come to the same conelusion: mental disorders are largely underrecognized in primary care. GPs fail to recognize mental disorders, particularly when the Inhibitors,research,lifescience,medical task is to make a specific diagnosis, whereas the more unspecific task of determining whether a given patient has at least some form of mental disorder (“mental health caseness”) seems to be somehow

better. Although improvement in diagnosis has been the target of countless campaigns over the past two decades on all levels (patients, doctors, and the public), for example, in depressive disorders, improved rates of caseness and diagnostic Inhibitors,research,lifescience,medical recognition are rare or at best quite moderate. The upper limit of the correct recognition of depressive disorders is at most somewhere between 50% and 70%, if threshold major depressive disorders or nicotine dependence are considered. For diagnoses that have received less attention, such as GAD, eating disorders, substance abuse disorders, and somatoform disorders, recognition rates are usually in the range of 30% to 50%. Crude comparisons over the past two decades in regions with campaigns to improve recognition have SRT1720 purchase revealed some,

albeit moderate, Inhibitors,research,lifescience,medical effect. However, Inhibitors,research,lifescience,medical some studies have also pointed out that using recognition rates as a measure of the quality of doctors’ diagnostic decisions might be misleading and suggested that it is inappropriate to assume that patients will have a better outcome if they are diagnosed and treated. As noted and discussed recently by Goldberg56 and Hôfler and Wittchen,57 higher recognition rates might occur at the expense of doctors’ oversensitivity and increased willingness to diagnose mental disorders at the expense of specificity. Obviously, many patients who clearly fail to meet criteria for depression according to the ICD-10 or the DSM-TV receive a diagnosis of depression by the doctors. The ongoing controversies very of lowering the criteria thresholds for MD and/or defining new forms of subthreshold depressive disorders (brief recurrent depression, mixed anxiety/depression, etc) could have added to this problem. However, this tendency toward increased willingness to assign depression diagnoses is not without danger. As noted by Hôfler and Wittchen,57 it remains open, for example, whether established treatments for MD are as effective in these subthreshold manifestations.

Also proposed for DSM-5 was the retention of six personality diso

Also proposed for DSM-5 was the retention of six personality disorder types (ie,

borderline, antisocial, schizotypal, narcissistic, obsessive-compulsive, and avoidant) that would have been diagnosed in large part by a list of maladaptive personality traits,4 consistent with the FFM prototype matching approach developed by Miller et al.75 For example, Inhibitors,research,lifescience,medical the diagnostic criteria proposed for DSM-5 borderline personality disorder included emotional lability, anxiousness, separation insecurity, depressivity, impulsivity, risk taking, and hostility.5 These seven traits aligned closely with scales from the Five Factor Borderline Inventory (FFBI67): Affective Dysregulation, Anxious Uncertainty, Despondence, Behavior Dysregulation, Rashness, and Dysregulated Anger. The FFBI though goes further than the DSM-5 to include such additional traits as self-disturbance, fragility, Inhibitors,research,lifescience,medical distrust, manipulation, and oppositionality. There are, however, some important differences between the FFM of personality disorder and the proposed DSM-5 dimensional trait model. The latter was largely a unidimensional model.27,76 Persons who are low in DSM-5

antagonism (for instance) were not Vorinostat datasheet considered to have any maladaptive personality traits. They simply lacked the trait of antagonism. The FFM has a bipolar structure, such that opposite to antagonism is agreeableness, with its own maladaptive variants. It is generally better to be extraverted than introverted, but Inhibitors,research,lifescience,medical gregariousness can turn into attention-seeking and inappropriate flirtatiousness, normal assertiveness can become pushiness and authoritarianism, and normal excitement-seeking can become Inhibitors,research,lifescience,medical recklessness and excessive risk-taking.77 Similarly, an individual rated high in agreeableness is traditionally considered to be prosocial, cooperative, pleasant, giving, considerate, kind, and honest. These traits are nearly universally valued as positive, and may even be described as virtuous. However, when taken Inhibitors,research,lifescience,medical to their extremes, they can be quite maladaptive, as trusting becomes gullibility, altruism becomes self-sacrificing selflessness,44 compliance becomes subservience, and modesty becomes self-effacement.43,77

These maladaptive variants of extraversion and agreeableness are either not present within the DSM-5 proposal (eg, excluded are gullibility and self-effacement) or they Casein kinase 1 are placed within other domains (eg, submissiveness is placed within neuroticism and attention-seeking is placed within antagonism). (Figure 1). provides a few illustrative traits at both poles of the five domains of the FFM. Figure 1. Illustrative traits within the five-factor model. One concern that has been raised with respect to the FFM of personality disorder is its potential complexity.78 To the extent that the model is comprehensive in its coverage of maladaptive personality functioning there is indeed the potential for any particular individual’s FFM profile to be exceedingly complex. Figure 1 provides only a few illustrative traits.

Secondly, none of the studies were set in a tertiary level, urban Middle Eastern hospital. Thirdly, with a few exceptions, most of the studies had very small and biased samples [7,21]. Finally, only one

study, rigorously evaluated the effect of a fast track system on urgent patients [17]. The aim of this study was to determine if a FTA improved both effectiveness in service delivery (WTs and LOS) and quality measures (LWBS rates and mortality rates) for patients with minor injuries and illnesses classified according to the Canadian Triage Acuity Scale 4 and 5 (CTAS 4/5), without delaying the care of urgent patients (CTAS 2/3). Methods Study Setting and Design This study took place in a 500 bed urban tertiary Inhibitors,research,lifescience,medical care general hospital, BYL719 Sheikh Khalifa Medical City, in the United Arab Emirates (UAE). The public emergency care facility serves residents of Abu Dhabi (capital city of the UAE) and surrounding Inhibitors,research,lifescience,medical areas. In 2005, the ED had an annual census of approximately 70 000 patients. The study

population consisted of adult and pediatric patients (defined as patients less than 12 years old as per hospital policy). The ED included a three-bed resuscitation area, and 15 monitored acute treatment beds (total of 18 ED beds) in the pre-fast track period and 7 additional FTA beds after the intervention (total of 25 Inhibitors,research,lifescience,medical beds). This was a single center study of ED department services at our hospital which provides all Inhibitors,research,lifescience,medical major medical, surgical and pediatric disciplines. The FTA was opened in February 2005. All patients entering the ED were seen by triage nurses and classified according to the Canadian Triage and Acuity Scale (CTAS) [22]. The low acuity patients (CTAS 4 and 5) were then treated, referred or discharged by the

physician from the FTA. Urgent patients (CTAS 2 and 3) were seen in the main ED. The CTAS is a 5 level triage scale Inhibitors,research,lifescience,medical based primarily on the patients presenting complaint and physiologic parameter. The CTAS guidelines are to ensure timely access to physician assessment on the basis of triage acuity level. A patient in CTAS 1 (resuscitation) requires immediate attention. CTAS 2 (emergent) should be seen within 15 minutes. CTAS 3 (urgent) should be seen within 30 minutes PAK6 and the non urgent, CTAS 4 and 5 should be seen within 60 minutes and 120 minutes respectively. The typical patient in CTAS 4 and 5 is ambulatory, does not need extensive investigation and contributes to < 10% of total admissions. The characteristics of our FTA are as follows: It has seven beds, is operational 24 hours a day, is staffed by either one or two Arabic speaking doctors at any time (of which 40% are house-officers and 60% are specialists with ED experience but no formal certification) depending on peak visits, sees only CTAS 4/5 (non-urgent) patients and performs only point of care laboratory testing e.g. pregnancy tests, urine dipsticks, glucose and chest X rays.

Results on purified protein derivative test were negative. The patient required initiation of continuous bladder irrigation (CBI) and packed red blood cell transfusion. On hospital day 5, the patient was taken for cystoscopy, clot evacuation, and ureteroscopy. Diffuse clot was irrigated from the bladder. Multiple bullous lesions in the bladder were biopsied and fulgurated. Retrograde

pyelogram revealed moderate right hydroureteronephrosis with filling defects in the ureter and pelvis. Ureteroscopy revealed inflamed renal pelvis mucosa; however, visualization Inhibitors,research,lifescience,medical was limited secondary to large clots filling portions of the collecting system. Washings were sent for cytology, AFB, and culture. Multiple biopsies were taken, and a double-J GSK126 chemical structure ureteral stent was placed. Pathologic analysis revealed urothelial tissue with hemorrhage and focal chronic inflammation. The patient had an uneventful postoperative course, was draining clear urine, and was discharged home. Hematologic consultation revealed no Inhibitors,research,lifescience,medical coagulation disorders. One week later the patient was readmitted to the hospital with recurrent gross hematuria. Renal MRI/magnetic resonance angiography showed improved right hydroureteronephrosis

and no vascular malformation or fistula. The patient’s bleeding persisted despite Inhibitors,research,lifescience,medical CBI and repeated transfusion therapy, and he was taken for laparoscopic right nephroureterectomy on hospital day 4. Postoperative oozing continued from the bladder cuff site, requiring transurethral fulguration Inhibitors,research,lifescience,medical on postoperative day 2. On postoperative day 4, decreasing hematocrit prompted a computed tomography scan that revealed retroperitoneal hematoma and significant blood in the subcutaneous tissues; thus, re-exploration through the kidney extraction site was performed and was negative for active bleeding. Pathologic evaluation of the right kidney and ureter revealed kidney and ureter with marked luminal hemorrhage in the ureter. The sections showed extramedullary hematopoiesis (EMH) in the

Inhibitors,research,lifescience,medical renal parenchyma extending into the perirenal fat (Figure 2A–C). The infiltrate was composed predominantly of left-shifted myeloid and monocytic precursors (highlighted by immunohistochemical stains for myeloperoxidase much and lysozyme) and dysplastic megakaryocytes and normoblasts. Few scattered lymphoblasts (CD34+, CD117+) were present within the infiltrate, without evidence of discrete aggregates. Admixed within the infiltrate were polytypic plasma cells and lymphocytes. These findings are characteristic of the involvement of the renal parenchyma and the ureter by CMML. A follow-up bone marrow biopsy showed a hypercellular marrow for age with myeloid hyperplasia and erythroid and megakaryocytic hypoplasia with megakaryocytic dysplasia. The abovementioned bone marrow findings-increased WBC count (17.

7 Vincristine sulphate was used as positive control. The find more thrombolytic activity was evaluated by the method developed by Prasad et al (2006)8 by using streptokinase (SK) as positive control. The membrane stabilizing activity of the extractives was assessed by evaluating their ability to inhibit hypotonic solution and heat induced haemolysis of human erythrocytes following the method developed by Omale et al (2008).9 Antimicrobial activity was determined by disc diffusion method.10 For all bioassays, three replicates of each sample were used for statistical analysis and the values are reported as mean ± SD. The present study was undertaken to evaluate the antioxidant potential in

terms of total phenolic content, phosphomolybdenum total antioxidant capacity and free radical scavenging property; cytotoxic, thrombolytic, membrane stabilizing and antimicrobial activities of different Afatinib organic and aqueous soluble materials of the crude methanol extract of A. blanchetii. In DPPH free radical scavenging assay, different extractives of A. blanchetii demonstrated free radical scavenging potential with IC50 values ranging from 40.50 to 119.21 μg/ml. The highest free radical scavenging activity was demonstrated by the carbon tetrachloride soluble fraction (IC50 = 40.50 ± 0.32 μg/ml) which could be correlated to its phenolic content 21.08 ± 0.41 mg

of GAE/g of extractives. A positive correlation was seen between total phenolic content and total antioxidant activity of A. blanchetii ( Table 1). In case of brine shrimp lethality bioassay, all the fractions demonstrated significant cytotoxic potential inhibitors against A. salina with LC50 values ranging from 0.78 to 92.82 μg/ml. The hexane soluble fraction revealed the highest cytotoxic activity with LC50 value 0.78 ± 0.74 μg/ml as compared to 0.45 μg/ml

for Vincristine sulphate ( Table 1). The extractives of A. blanchetii demonstrated mild to moderate thrombolytic activity. The chloroform soluble fraction showed 32.50 ± 0.63% of clot lysis as compared to 66.77% clot lysis by standard streptokinase ( Table 2). At concentration 1.0 mg/ml, the extractives of A. blanchetii protected the haemolysis of RBCs induced by hypotonic solution and heat as compared to the standard acetyl salicylic acid (0.10 mg/ml). The not chloroform soluble fraction inhibited 46.74 ± 0.73% and 41.33 ± 0.59% of haemolysis of RBCs induced by hypotonic solution and heat as compared to 71.90% and 42.12% by acetyl salicylic acid, respectively ( Table 3). The antimicrobial activity of A. blanchetii test samples was evaluated against 5 gram positive and 8 gram negative bacteria and three fungi and the results were compared with standard antibiotic, ciprofloxacin. The test samples of A. blanchetii revealed antimicrobial activity with zone of inhibition ranging from 7.0 to 13.0 mm. The highest zone of inhibition (13.

We also investigated the association between noncontinuous use and relapse or recurrence within 1 year of starting treatment and the factors associated with noncontinuous antidepressant use. Material and Methods Study design, source of data, and patient population This retrospective cohort study was conducted in the Prince of Wales Hospital (PWH) in Shatin, Hong Kong. The study was approved by the Joint Chinese University

of Hong Kong and New Territories East Cluster Inhibitors,research,lifescience,medical (CUHK-NTEC) Clinical Research Ethics Committee (CREC) in July 2008. Eligible patients were identified through data retrieval using the Clinical Data Analysis and Reporting System (CDARS). This centralized-computerized database stores longitudinal clinical information including patient demographics, prescription, and dispensing records, and diagnosis patients

received from all public hospitals in Hong Kong. Patients were included if Inhibitors,research,lifescience,medical (1) he or she was aged >18 years, (2) was attending Psychiatric Specialist Outpatient Clinic (SOPD) of PWH during the period between 1st January 2006 to 31st December 2007, (3) had an antidepressant dispensed during the study period, and Inhibitors,research,lifescience,medical (4) were diagnosed with major depressive disorders according to the International Classification of Disease-10 classification of mental and behavioral disorders. Subjects were excluded if they had (1) concurrent diagnosis Inhibitors,research,lifescience,medical of bipolar disorder, obsessive-compulsive disorder, psychosis, schizophrenia, substance abuse, post-traumatic stress disorder, acute stress disorder, and panic

disorders, or (2) a diagnosis of dementia or mental retardation, or (3) a prescription of antidepressants 6 months prior to the study period, or (4) documented concurrent psychiatric-related follow-ups in other health care settings (where they may also had been prescribed antidepressants), or 5) history of drug overdose or suicide. If there were more than one period of antidepressant use during the study period, Inhibitors,research,lifescience,medical only the first episode was counted. Electronic patient buy PCI-32765 records were then reviewed to confirm the eligibility. Further information regarding the antidepressant use and relapse and recurrence after treatment initiation was supplemented by reviewing the written medical records. Data collection A standard form was designed for collecting the patient-, illness- and treatment-related parameters. These included demographics such as age, gender, type of accommodation (as an indirect indictor for socioeconomic status) and marital status. Details of treatment regimen including drug name, dosage, frequency, duration, and prescription refill pattern were documented. Other treatment-related factors such as the frequency of follow-up were also recorded.
