A suspension is a dispersed system in which the internal phase consists of solid particles and the external phase is a liquid Inhibitors,research,lifescience,medical vehicle. Suspensions are the best conventional liquid dosage forms of drugs with high bioavailability in comparison to other dosage forms except solutions, and they have patient compliance [1, 2]. Rheological study of suspensions provides valuable information for efficient utilization, Selleck INK 128 transport, and handling of materials in industrial applications

[3]. The thixotropy and hysteresis loop Inhibitors,research,lifescience,medical are rheological phenomena. In non-Newtonian systems if the rate of shear was reduced once the desired maximum rate had been reached, the down curve can be displaced relative to the up curve. With pseudoplastic systems, the down curve is frequently displaced to the left of the up curve. This phenomenon, known as thixotropy, can be defined as an isothermal and comparatively slow recovery, on standing of a material, Inhibitors,research,lifescience,medical which has lost its consistency through Inhibitors,research,lifescience,medical shearing [4, 5]. The area surrounded between ascending and descending curves that is called hysteresis loop can give information about the structure breakdown and

rebuilding [4, 6, 7]. Controlled flocculation and rheologic modification are important factors in preparation of suspensions. Flocculated suspensions are settled rapidly to form large loose and easily dispersible sediments [8]. Non-Newtonian polymers are utilized in the industries such as food, textile, pharmaceutical, and cosmetics. They are employed in suspensions as structural vehicles and exhibit non-Newtonian (plastic or pseudoplastics) flow with some degree of thixotropy. Various types of polymers are used as 4-Aminobutyrate aminotransferase rheology control agents such as CMC, methylcellulose, NaCMC, PVP, xanthan gum [6, 9–11], poloxamer [12], tragacanth [13], chitosan [6], and Veegum [14]. Acetaminophen is an analgesic and antipyretic agent whose oral delivery especially to children is combined with trouble due to bitter and unpleasant taste. One of the methods to achieve the maximum taste masking characteristic is to formulate the drug in suspension form which creates a physical fence around the drug [15, 16].

Effective communication is not a function of time but rather one

Effective communication is not a function of time but rather one of skill. Few extra seconds spent on each tasks are actually time efficient and can decrease inappropriate workup, interpersonal conflict, and litigation, and can enhance compliance with follow-up care [53]. Thus, though the time factor is generally blamed for this, this should not necessarily be the case because good communication

can be part of the triage process itself. As such, respect for autonomy may be realized as much as possible in ED situations. Nonmaleficence Inhibitors,research,lifescience,medical The principle of nonmaleficence can be described as “do no harm”. The Hippocratic Oath mentions this obligation as “I will use treatment to help the sick according to my ability and judgment, but I will never Inhibitors,research,lifescience,medical use it to injure or wrong them” [12]. One ought not to inflict evil or harm. Harm is not directly inflicted by triage except when hopelessly injured patients are considered

in the dead category. Even during disasters, under given circumstances; health care professionals are always obligated Inhibitors,research,lifescience,medical to provide the reasonably best care. The aim is to secure fair and equitable resources and protections for vulnerable groups [54]. Waiting long for a consultation can increase pain and suffering and, at times, worsen the outcome and thus, result in indirect harm. Psychosocial harm includes stress, fear, feeling neglected or not being taken care of. Triage guidelines aim to avoid harm to the patient by sorting the patients as quickly and Caspase pathway efficiently as possible. However, in emergency care, especially in situations Inhibitors,research,lifescience,medical of overcrowding, treating one patient might threaten the

welfare of another patient by not being able to take care of both. Studies in different centres have found Inhibitors,research,lifescience,medical an association between overcrowding and reduced access to care, decreased quality measures, and poor outcomes [55]. Sometimes, referral to other centres can result in more quick and effective service and thus, harm in the form of excessive delays may be avoided [18]. Furthermore, medical care is not only the diagnosis and treatment in emergency care; patients mafosfamide value effective communication and short waiting times over many other aspects of care [56]. Lack of communication of triage times and categories is one of the causes of aggression and violence of patients and accompanying persons towards emergency staff [57]. Crilly et al. reported around 67% of patients who exhibited violent behaviour either did not wait for treatment or had been in the emergency room for less than one hour [58]. Ekwall et al. suggest the importance of addressing the psychosocial needs of patients of varying levels of urgency through their social interactions at triage [59]. Existing triage guidelines [17,27] miss to incorporate this aspect of care, which can compromise the principle of nonmaleficence.

No significant superiority of one variant of PD over another has

No significant superiority of one variant of PD over another has been convincingly demonstrated. Surgeon’s experience with the specific variant of PD appeared to be the determining factor in achieving optimal surgical outcome. Distal pancreatectomy Distal pancreatectomy is the standard procedure for cancer of the body or tail of pancreas. It entails the resection of distal portion of pancreas extending from the left of the superior mesenteric vein / portal vein axis to the tail with en bloc resection of surrounding lymphatic tissue.

Spleen is conventionally removed with the procedure. Spleen-sparing distal pancreatectomy (Warshaw operation) can be performed Inhibitors,research,lifescience,medical safely without increase in complication rate, operative time or in-hospital stay (45). While cancer of the body and tail tends to present at an advanced stage due to the Inhibitors,research,lifescience,medical lack of early symptoms and tends not to be amenable to complete resection on presentation, there is no survival difference

when compared with cancer of the head Inhibitors,research,lifescience,medical of pancreas stage by stage (46),(47). Laparoscopic pancreatic resection With the publication of COST trial, minimally invasive surgical approach has been evaluated in increasing frequency for cancer resection (48). For the surgical management of pancreatic neoplasm, laparoscopic distal pancreatectomy (LDP) is rapidly becoming the surgical procedure of choice in place of open distal Inhibitors,research,lifescience,medical pancreatectomy (ODP) for tumor of the body/tail of pancreas. While several groups have published their results with LDP, the majority of the publication did not specifically address the oncologic outcome following LDP for pancreatic cancer (49)-(59). Overall, when compared with ODP, LDP is associated with a longer operative time,

less blood loss, and shorter length of stay. Conversion rate from laparoscopic approach to open varies between 0 to 30%. In their institutional experience, Baker et al noted a lower number of lymph nodes harvested in 27 LDP patients (mean=5) compared with 85 ODP patients (mean=9) Inhibitors,research,lifescience,medical (57). Kooby et al performed a matched analysis of 23 LDP patients with 189 about ODP patients from a database with pooled data from 9 c-Met inhibitor academic centers (58). There was no difference in positive margin rates, number of lymph nodes examined, or overall survival in patients with pancreatic cancer. Jayaraman et al reviewed their results of 343 distal pancreatectomies over a 7-year study period at Memorial Sloan-Kettering Cancer Center : 107 were attempted laparoscopically and 236 ODP (59). The conversion rate was 30%. Similar complication rates were observed in both groups. They also observed significantly less blood loss, longer operative times, and shorter hospital stays in favor of LDP group. The number of lymph nodes examined (LDP = 7 vs. ODP = 7) and margin positivity (LDP = 3% vs ODP = 4%) were similar between both groups.

Tissue samples were gathered from consenting patients at the time

Tissue samples were gathered from consenting patients at the time of diagnostic procedures or at primary curative surgical resection at Galway University Hospital, Ireland. The cohort comprised of 101 colorectal tumour specimens, 8 TWS119 research buy polyps and 107 TAN tissues. Following retrieval, all samples were subject to

histopathological review prior immediate snap-freezing in liquid nitrogen and archival at -80 °C until further use. Concomitant clinicopathological data on patients and specimens was obtained through patient interview and review of clinical notes. Inhibitors,research,lifescience,medical Ethical approval for this study was granted by the Clinical Research Ethics Committee, Galway University Hospitals. Table 2 Clinico-pathological data for patients used for gene expression analysis RNA extraction and analysis Tissue Inhibitors,research,lifescience,medical samples (50-100 mg) were homogenised using a hand-held homogenizer (Polytron PT1600E) in 1-2 mL of QIAzol reagent

(Qiagen) as described previously (32). In brief, tumour and TAN samples were homogenised separately but on the same day. RNA was extracted using RNeasy Plus Mini kits (Qiagen) according to the manufacturer’s instructions. RNA was eluted in 60 µL volumes and stored at -80 °C. RNA concentration and purity was assessed in duplicate samples using a using a NanoDrop ND-1000 Inhibitors,research,lifescience,medical spectrophotometer (NanoDrop). RNA integrity was evaluated using the RNA 6000 Nano Chip kit (Series II) and the Agilent 2100 Bioanalyzer (Agilent Technologies). An RNA integrity number (RIN) was generated for each sample using the Agilent 2100 Expert Software (Version B.02.03) based on the ratio of ribosomal

bands and also the presence or absence of degradation products on the electrophoretic and gel-like images. A threshold value Inhibitors,research,lifescience,medical of RIN ≥7 was applied and RNA purity was verified by an average A260/A280 ratio of 1.98 (range, 1.97-2.01) and A260/A230 ration of 1.7 (range, 1.5-1.83). Reverse transcription RNA was reverse transcribed to first strand cDNA using Superscript III reverse transcriptase (Invitrogen) and random primers (N9; 1 µg, MWG Eurofins). Negative control samples were included in each set of reactions. Inhibitors,research,lifescience,medical Reactions were incubated at 25 °C for 5 minutes followed by 50 °C for 1 hour and final denaturation at 72 °C for 15 minutes. Samples were subsequently diluted to 100 µL in nuclease-free water and stored at -20 °C. Real-time quantitative PCR Amplification efficiency The amplification efficiency of each assay is an important consideration in the Chlormezanone determination of relative quantities of gene expression by RQ-PCR. PCR efficiency impacts greatly on the accuracy of the calculated expression result and is influenced by PCR reaction components. For 100% efficiency a doubling of the amount of DNA will occur at each cycle, while for 80% and 70% the amount of DNA will increase from 1 to 1.8 and 1.7, respectively. Resultantly, small differences in efficiency can greatly affect the calculation parameters involved in the determination of gene expression values.

The decrease in iNOS mRNA observed in this study cannot be attrib

The decrease in iNOS mRNA observed in this study cannot be attributed to genetic constitution of DMD, but can be explained by a growing number of studies that have shown that moderate (i.e. non-cytotoxic) oxidative stress down-regulates the expression of various genes (69). Accordingly, laser repaired this gene repression as exposure to energy dose 2 Joules/cm2; has been shown to increase in both transcription and translation activities in cells (70). This study reveals that oxidative stress is the prime cause for muscle degeneration in DMD, points

out to the possible ameliorative effect of He:Ne laser on Inhibitors,research,lifescience,medical this stress and shows that assessment to replicate ageing and oxidative stress in circulating peripheral blood cells is a reliable non-invasive technique.
Glycogen Storage Disease type

Inhibitors,research,lifescience,medical III (GSDIII; Cori-Forbes Disease; OMIM 232400) is an autosomal recessive disorder due to the deficiency of amylo-1,6-glucosydase, 4-α-glucantransferase enzyme (AGL, or Glycogen Debrancher Enzyme, GDE) which degrades glycogen branches releasing glucose in a two step reaction catalysed by its two distinct activities. GSDIII was first observed in the ’30s by van Creveld; in 1952 Illingworth and Cori described the abnormal structure of GSDIII glycogen Inhibitors,research,lifescience,medical (1). In 1953 Forbes correlated the abnormal glycogen structure with the typical symptoms of GSDIII (2). The AGL gene was cloned in 1992 (3). The main clinical phenotypes of this disease are due to involvement of liver and/or muscle. Phenotypic expression is highly variable. GSDIII features can be distinguished Inhibitors,research,lifescience,medical in two presentations, Inhibitors,research,lifescience,medical according to patient’s age. Infancy and childhood are characterised by recurrent fasting hypoglycemia, seizures, hepatomegaly, decreased muscle tone and growth retardation. During childhood and

early adulthood the symptoms seem to regress and most patients have only minimal signs of liver disease (4). The predominant symptoms in the adult form are distal weakness, affecting calves and peroneal muscles mostly, and proximal SRT1720 supplier weakness at a variable degree with a slow disease progression. Back pain and fatigue may be present. A number of patients show serum creatine kinase (CK) increase of 5-45 folds. for Neuropathy may occur due to glycogen storage in Schwann cells and axons. Hepatic dysfunction persists in few patients and cardiomyopathy, if present, is rarely severe. Debranching enzyme is a single 1532 aminoacid chain weighing about 165 kDa and consisting of two independent catalytic activities: oligo-1,4-1,4-glucantransferase [EC 2.4.1.25] and amylo-1,6-glucosidase [EC 3.2.1.33], localised in two distinct protein regions (5, 6).

41 Some studies have shown benefit from SSRIs;47 yet

trauma-focused CBT has shown more consistent effectiveness.47 To date, no RCTs have examined medication effects in children or adolescents with panic disorder. Aside from SSRIs, medications with dual inhibiting actions on serotonin and norepinephrine (SNRIs) have also been tested in youth with anxiety disorders. Specifically, venlafaxine XR was examined in two 8-week RCTs in children with GAD. Despite insignificant improvement on a primary measure in one of the trials, pooled results Inhibitors,research,lifescience,medical revealed significantly greater response in the active medication group compared with placebo. 48 Another 16-week RCT of venlafaxine XR in children with social anxiety showed significant benefit beyond placebo.49 However, studies of venlafaxine Inhibitors,research,lifescience,medical in children click here indicated a risk for elevated blood pressure, decreased growth rate, and increased suicidal ideation, which should be considered with families prior to initiating treatment. A meta-analysis of RCTs examining the tolerability and efficacy of pharmacotherapy for anxiety disorders found that SSRIs and SNRIs showed clear benefit with an overall response rate almost double that of placebo treatment, with SSRIs slightly more beneficial than venlafaxine XR.23 Inhibitors,research,lifescience,medical Due to the lack of comparative head-to-head RCTs

of SSRIs or SNRIs, choice of agent is often based on side-effect profiles, interactions with other medications, and family history of medication response. Furthermore, only short-term

benefits have been evaluated in RCTs, and research findings may not generalize to clinic populations Inhibitors,research,lifescience,medical due to exclusion of youth with medical or psychiatric comorbidities. Inhibitors,research,lifescience,medical Age may also be an important consideration in pharmacotherapy. Despite age-related differences in metabolism and observations that SSRIs may be more effective in the treatment of adolescent depression compared with depressed younger children, findings from RCTs in anxious youth do not show differential effects based on age.23, 50 The evidence base is particularly limited for pharmacologic treatment of anxiety in children under the age of 6.51 Given the limited pharmacologic data, CBT, tailored to developmental level, is considered to be the Tolmetin first line treatment in children this young. In cases with high acuity unresponsive to psychotherapy, medication treatment may be considered. Safety concerns with SSRIs and SNRIs Heightened concern for the negative effects of SSRIs and SNRIs in youth, particularly for activation and emerging suicidality, have impacted familial willingness and clinical practice to initiate treatment with these agents, particularly for children with anxiety.

We, and others, have aggressively investigated this question sinc

We, and others, have aggressively investigated this question since stroke: (i) is a major form of neurodegeneration

that Selleck ITF2357 grossly impacts our aging population, and (ii) has been successfully reproduced in several animal models. To date, most clinical studies have assessed whether ERT alters the risk and mortality of stroke,44 but have not addressed whether estradiol decreases the degree of brain injury resulting from stroke. Stroke is a neurodegenerative condition that greatly impacts the health and livelihood of our aging population. It is the third leading cause of death for middleaged and older women, and a major health problem that affects 500 000 Americans Inhibitors,research,lifescience,medical each year.45 Interestingly, premenopausal women are at a lower risk for stroke than men of the same age.46 However, after the menopause the incidence of cerebrovascular disease Inhibitors,research,lifescience,medical rises rapidly.47 These clinical observations parallel statistics on the prevalence of stroke with regard to age and sex: at a younger

age, women appear to be protected Inhibitors,research,lifescience,medical against stroke, compared with men, but lose this advantage in their postmenopausal years (Figure 1).48 Together, these data suggest that endogenous estrogen plays a protective role against stroke. Since stroke imposes major morbidity and mortality in postmenopausal women, it is critical to determine whether ERT may decrease the risk and/or severity of cerebrovascular disease. Figure 1. Endogenous estrogen may decrease the risk for

stroke. Prior to the menopause, women appear to be protected against the occurrence of stroke, compared with age-matched men (left). However, this protection is lost at Inhibitors,research,lifescience,medical some time after the menopause (right), … Classification of stroke Stroke results in infarction of the brain. Major causes and risk factors for stroke include coronary artery disease, cardiac failure, diabetes, hypertension, atherosclerosis, and thrombotic conditions. The overlapping Inhibitors,research,lifescience,medical and often mixed etiologies of stroke can result in two major types of pathology: ischemic stroke or hemorrhagic stroke. Briefly, clot(s) in the cerebro vasculature produce ischemic infarct, and the bursting of cerebral vessel (s) causes subarachnoid hemorrhage. Estrogen and stroke risk Several lines of evidence suggest that ERT may reduce the likelihood for stroke by modifying risk factors that underlie both stroke and coronary heart, disease (CHD).44 Resminostat For example, estrogen may protect by exerting beneficial effects on diabetes and on the scrum lipid profile.49,50 Interestingly, CHD doubles the risk for stroke and ERT greatly reduces the risk for CHD (by 30% to 40%). It thus follows that estrogen may decrease the risk for stroke in parallel with its protective actions on CHD. In contrast to protection, estrogen may, under some circumstances, impose an increased risk for stroke by influencing coagulation and fibrinolysis.

Secondly, none of the studies were set in a tertiary level, urban

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, 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 Selleck AVL301 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 not 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.

Fig. 5 Follow-up chest X-ray. At a follow-up, a posteroanterior chest X-ray view shows normalized heart size at 16 months after thyroid hormone supplementation and heart failure treatment. Table 1 Echocardiographic findings with TSH levels Discussion Hypothyroidism is associated with decreased cardiac

contractility, increased systemic vascular resistance and decreased cardiac output. Its manifestations are insidious and subtle in Inhibitors,research,lifescience,medical its progression and clinical behavior.4) DCM, the most common form of cardiomyopathy, may be caused by various factors such as metabolic/endocrine disturbances, electrolyte imbalances, inflammation, infection, immune system disorders and toxins.10) Thyroid hormones act on the cardiac myocyte and peripheral vasculature. The genomic and non-genomic effects

of thyroid hormone are related to the cardiac Inhibitors,research,lifescience,medical function and cadiovascular hemodynamics.4) To explain their possible genomic effects on the cardiovascular system, it has been proposed that they involved in the regulation of the mRNA transcription of genes associated with Inhibitors,research,lifescience,medical the contractile system.1) They have a non-genomic effects on the ionic channels of cardiomyocyte’s membrane.4) AZD2014 cost Patients with hypothyroidism present with cardiovascular manifestations such as bradycardia, decreased contractility of the myocardium, increased systemic peripheral vascular resistance and the pericardial effusion. Moreover, patients with hypothyroidism are many at increased risks of developing atherosclerosis and ischemic heart disease.11),12) It has been reported that the cardiac manifestations are associated with alterations in the expression of T3-mediated genes in patients with thyroid dysfunction.4) Patients with hypothyroidism are less likely to develop heart failure although their cardiac output is decreased. This is due to their lower degree of oxygen demand.13) In the current case, the patient had no family history of DCM. In addition, the patient also had no past history of alcohol abuse or history of other drug or substance addiction. The echocardiographic findings were suggestive of DCM.

Statistical analysis All statistical analysis was completed wi

.. Statistical analysis All statistical analysis was completed with SPSS v 16.0 (SPSS, Chicago, IL). Group comparisons were completed on each of the demographic variables and saccade variables using one-way analysis of variance (ANOVA). When the ANOVA assumption of equal variances was not met (e.g., prosaccade errors, antisaccade: error rates, corrections, fixations, Inhibitors,research,lifescience,medical and omissions), the Welch’s robust tests of equality was utilized (Welch 1947). To assess antisaccade error rates in milder levels of AD, additional analysis was conducted on the subgroup with MMSE scores >22 and another subgroup with MMSE scores >24. The first subgroup, with MMSE scores >22 was selected to provide a

direct comparison with the study of Boxer and colleagues (Boxer et al. 2006), while the second Inhibitors,research,lifescience,medical group (MMSE >24) was selected because an MMSE score of 24 is usually considered a cutoff point for dementia. Sensitivity, specificity, positive predictive value, and negative predictive

value were calculated to assess the diagnostic capacity of antisaccade errors, uncorrected errors, and JAK inhibitor fixation errors. Sensitivity and specificity calculation required binary classification of performance; therefore, antisaccade performance was categorized as impaired (two standard deviations above the normal controls [NC] mean) or unimpaired (under two standard deviations of the NC mean). The effect Inhibitors,research,lifescience,medical size of antisaccade error rates was calculated with Cohen’s d, (the mean difference in antisaccade errors between the two groups, divided by the pooled standard deviation) (Cohen 1998). Values derived from the Cohen’s Inhibitors,research,lifescience,medical d test are categorized into effect sizes that are small (0.2–0.5), medium (0.5–0.8), and large (≥0.8) (Cohen 1992). Results Demographic data for the 61 participants showed no significant baseline differences as summarized in Table 1. Performance metrics

are summarized in Table 2. Patients with AD not only made significantly more errors on both the prosaccade (F(1,47.6)= 4.76, P < 0.05) and antisaccade tasks (F(1,47.6)= 24.72, P < 0.001), but also left significantly more antisaccade errors uncorrected (F(1,29.5)= Inhibitors,research,lifescience,medical 22.3, P < 0.001). During the antisaccade task, patients made significantly more fixation errors (F(1,31.7)= Mephenoxalone 23.6, P < 0.01) and omission errors (F(1,31.4)= 8.1, P < 0.01) compared with controls. Both subgroups with MMSE scores >22 (F(1,31.6)= 18.24, P < 0.001) and MMSE scores >24 (F(1,22.3)= 14.5, P < 0.01) made significantly more antisaccade errors than NC. Table 2 Antisaccade performance. Sensitivity and specificity, and cutoff scores are outlined in Table 3. While all of the metrics provided specificities greater than 0.9, sensitivity was low, with uncorrected errors showing the highest sensitivity (sensitivity = 0.63). Prosaccade errors were not included in sensitivity and specificity as the amount of performance overlap between the two groups was large (Cohen’s d = 0.56).
