6 Apart from the well-documented advantages of laparoscopic surgery over open surgery shared by pregnant and nonpregnant patients, additional benefits in pregnant patients include less respiratory depression because of reduced postoperative narcotics requirements, the lower risk of wound complications such Inhibitors,research,lifescience,medical as incisional hernia, decreased risks of thromboembolic events due to early mobilization, and diminished postoperative maternal hypoventilation.7 Moreover, with improved visualization,

laparoscopy reduces the risk of uterine irritability by decreasing the need for uterine manipulation and thus results in lower rates of spontaneous abortion and preterm delivery than open surgery.6 Certain limitations of laparoscopy during pregnancy have been highlighted, including fetal acidosis secondary to CO2 absorption, decreased uterine blood flow and alteration in placental perfusion secondary to pneumoperitoneum, fetal hypotension resulting from low maternal cardiac output, and injury Inhibitors,research,lifescience,medical to the www.selleckchem.com/products/at13387.html gravid uterus.6–8 In the absence of definitive evidence (Level I/Grade

A evidence) to date, many surgeons believe that pregnancy may be a contraindication to laparoscopy.5 However, experience with cholecystectomy, appendectomy (Level II/Grade B evidence), and adrenalectomy Inhibitors,research,lifescience,medical (Level III/Grade C evidence) suggests that such laparoscopic nonobstetric surgeries in pregnant patients can be safely Inhibitors,research,lifescience,medical done when standard precautions are taken.6,9–11 In a study by Reedy and colleagues,12 no differences were seen in fetal malformations or survival after laparoscopic (n = 2181) or open (n = 1522) abdominal nonobstetric surgeries during pregnancy. In another study, Holthausen and associates13 reviewed 112 laparoscopic

nonobstetric procedures during pregnancy, and found that the outcome of the mother and the baby delivered was excellent. At present, Inhibitors,research,lifescience,medical the experience of pure laparoscopic nephrectomy during pregnancy comprises only six cases performed to date (Table 1). Indication for operation was renal cell carcinoma (RCC) in five cases.5,14–17 In one case, retroperitoneoscopic nephrectomy was performed for giant hydronephrosis in a patient PAK6 at 9 weeks of gestation.2 Recently, a case of successful robot-assisted laparoscopic partial nephrectomy for RCC has been reported from South Korea (Table 1).18 Our case is the first case of pure transperitoneal laparoscopic nephrectomy performed for pyonephrotic nonfunctioning kidney during pregnancy. Table 1 Reported Cases of Laparoscopic Nephrectomy During Pregnancy Six of these reported procedures were performed during the second trimester and the remaining two during the first trimester.

06), while on day 5 it was 107.8 for controls and 101.6 for vaccinated animals (Wilcoxon rank-sum test P = 0.05). The vaccinated animals remained positive by RT-PCR on subsequent days post-challenge and some animals that were negative produced a positive result on later samples. By day 21, vaccinated horses were still positive by RT-PCR although infectious virus was undetectable by the end-point dilution assay. As expected, all four animals vaccinated with MVA-VP2(9) developed VNAb by the time of challenge with titres ranging between 1.6 to 2.4 (Table 3). Following AHSV-9 challenge these VNAb titres

increased more than four-fold in all four animals and the final titres Libraries recorded on day 28 post-challenge reached values of between 2.3 to more than 3.1. All non-vaccinated control horses were

negative for VNAb at virus challenge selleck inhibitor and did not develop VNAb before they succumbed to AHSV-9 infection. Antibodies to AHSV-VP7 were detected in serum samples of Obeticholic Acid the vaccinated horses only after challenge (Table 4). As expected all horses were negative by the VP-7 ELISA test on the day of challenge (day 34). This study in the disease relevant host, the horse, was aimed at determining the protective capacity of vaccines based onMVA-VP2 against virulent AHSV challenge. This work focused on AHSV-9. Thus, the MVA-VP2(9) recombinant vaccine was constructed using the genome segment encoding VP2 from the AHSV-9 reference strain (PAKrrah/09) and vaccinated animals were Bay 11-7085 challenged with the AHSV-9 strain KEN/2006/01.

Ponies immunised with MVA-VP2(4) in a previous study [13] and those vaccinated with MVA-VP2(9) in this study developed VNAb titres after two doses and reached titres against homologous virus, ranging between 1.8 to 1.9 or between 1.6 to 2.4, respectively. These results are in line with studies by others using poxvirus vectors expressing AHSV-VP2. Thus, horses vaccinated with 107.1 TCID50 of a canarypox-based AHSV vaccine [14] expressing VP2 and VP5 developed serum VNAb titres of 20–40 (1.3–1.6 log10); and use of a recombinant vaccinia virus (strain WR) expressing AHSV-4 VP2 also induced VNAb in horses [20], albeit at low titres and only after 3 vaccine inoculations. In this study, vaccination of horses with MVA-VP2(9) showed very high levels of protection despite the high challenge virus dose used. Clinical signs were completely absent in vaccinates and the rectal temperatures were within normal physiological ranges during the study period. In contrast, the control horses experienced a peracute AHSV cardiac syndrome accompanied by high rectal temperatures. Vaccinated animals were also completely protected against viraemia as measured by a standard end-point dilution assay demonstrating the potential of MVA-VP2 vaccination to prevent onward transmission by the insect vectors.

5 mg protein. Krebs-Ringer bicarbonate buffer containing 0.2% glucose and 0.2% bovine serum albumin (BSA) was then added to make up the total assay volume of 250 µl. The required protein concentration and incubation period were determined by the standard curve using various

concentrations. After incubation in a water bath at 37ºC for two hours, the reaction was VX-770 in vitro terminated by the addition of ethyl acetate Inhibitors,research,lifescience,medical and the steroids were then extracted. The organic layer was separated by centrifugation at 3000 rpm and 4ºC for 10 min. The top layer was then transferred into new test tubes and evaporated to dryness at 55ºC in a vacuum concentrator. Steroid residues were dissolved in an ethanol containing nonradioactive carrier of 11-dehydrocorticosterone and corticosterone. Inhibitors,research,lifescience,medical They were then separated by thin layer chromatography, TLC (Whatman, UK) in 92:8 ratio of chloroform and 95% ethanol. The fractions corresponding to the steroids were located by UV lamp absorption at 240 nm, scraped, transferred into scintillation vials and counted Inhibitors,research,lifescience,medical in scintillation fluid (Cocktail T) in a Kontron Betamatic fluid scintillation counter (Merck, Germany). Enzyme activity was calculated as the percentage conversion of the active [3H] corticosterone to inactive [3H] 11-dehydrocorticosterone from the radioactivity of each fraction. Enzyme

activity was measured by the method used by previous studies with some modification.19,20 The statistical software used was the Statistical Package for Social Sciences (SPSS) version Inhibitors,research,lifescience,medical 12. The data was tested for normality using

the Kolmogrov-Smirnov test. Since the data were found to be normally distributed, they were analyzed using one-way Analysis of Variance (ANOVA) followed by Tukey pos-hoc test for pairwise comparisons A P value of <0.05 were taken as significant. Data are presented as mean±standard error of the means (SEM). Measurement of 11β-HSD1 Expression The formalin-fixed paraffin-embedded Inhibitors,research,lifescience,medical bone sections were deparaffinized and rehydrated. For antigen retrieval, the sections were incubated in 0.01M citrate buffer at 90ºC for 5 minutes. The sections then were incubated in 0.3% hydrogen peroxide for 10 minutes to block the endogenous peroxide activity and subsequently incubated in 1:50 normal goat serum (Vector Laboratories; Burlingame, CA) for 20 minutes to block nonspecific antibody binding. others Sections were incubated for 60 minutes with primary rabbit 11β-Hydroxysteroid Dehydrogenase (Type1) Polyclonal Antitbody, and detected by goat anti-rabbit peroxidase (Vector Laboratories, Burlinghame California) using DAB as a chromogen according to the manufacture’s instructions and counterstained with haematoxylin. Controls were done by using positive tissues (liver and adipose tissue) and omissions of the primary antibody. Photomicrographs taken were scored by two blind observers at 25 and 50 times magnification.

Studies in child click here psychiatric epidemiology have begun to focus far more on identifying explanations for specific patterns of comorbidity than simply documenting that, comorbidity is pervasive.63 Substance use disorders Trends of drug and alcohol use in high-school youth in the US arc carefully monitored by studies such as Monitoring the Future (MTF).65 The 2007 MTF survey that, encompassed nearly 50 000 8th-, 10th-, and 12th-gra.de students in over 400 secondary schools nationwide continues to show a decline in illicit drug use across the US. However, this survey Inhibitors,research,lifescience,medical does not collect information on substance use disorders. The median estimate of alcohol or drug

abuse or dependence in community surveys of adolescents is 5% with a range from 1% to 24%. 8 The results of the recent studies described in Table I yield similar estimates: 4.7%,13 5.3%, 14 2.4%, 12 and 1.7%.15 The lower Inhibitors,research,lifescience,medical rates in the latter two studies are likely to be attributed to the lower age range of these samples. For example, in the Great Smoky Mountains Survey, there was a dramatic increase in the rates of substance use disorders with age, with a 3-month prevalence rate of 0.3% at age 13,1.4% at age 14,5.3% at age 15, and 7.6% at age 16. Gender differences in prevalence rates of substance use disorders are inconsistent. Whereas several studies show Inhibitors,research,lifescience,medical equal prevalence rates in males and females,13 others show that males have greater rates than

females.14 Substance use disorders have been generally Inhibitors,research,lifescience,medical shown to be more common in white youths, and equally distributed by parental social class.66

Risk factors for mental disorders in youth Aside from providing extensive information on regional differences in mental disorders in the US, the majority of prior population studies of mental disorders in youth have also included longitudinal follow-up that provide information on the predictors and consequences of mental disorders.17,19,21,35,67,68 Prospective Inhibitors,research,lifescience,medical follow-up of youth from many of the above studies have shown that child and adolescent mental disorders are related to a wide array of adverse outcomes.69,70 Risk factors for the development of mental disorders in children have been divided into child characteristics and those of his/her parents/family. Child characteristics include gender, age, ethnicity, physical health, cognitive and psychological function, pre- and perinatal exposures to illness, physical stress, alcohol, drugs, nutrition, crotamiton infections and other environmental agents, and lifetime history of environmental exposures to toxins, stress, infections, social environment and stressful life events; family and parent characteristics including parental education, age, social class, employment, psychiatric and medical history, and family function, structure,7,10,19,71 and neighborhood and broader contextual influences on the health of children and their families.

88 Once again, they found elevated rates of psychiatric disorders (depression and substance abuse) before injury and increased rates of depression, PTSD, and other anxiety disorders subsequent to injury. This was particularly true of those with preinjury psychiatric disorders. Furthermore, the rates were greatest at the initial assessment point after injury and stabilized or decreased over time. Others have also reported increased indicators of psychiatric illness after TBI and increased medical costs associated with those indicators.89,90

More recently, Bryant et al91 have shown that there arc high rates of psychiatric illness Inhibitors,research,lifescience,medical in individuals hospitalized with traumatic injury of any sort (including mild TBI) 12 months after the event (31 %). Twenty-two percent suffered psychiatric disorders that they had never had before. Having a mild TBI was associated with higher rates of PTSD and other anxiety disorders. Inhibitors,research,lifescience,medical The combination of mild TBI and psychiatric illness was associated with greater degrees of functional impairment. Whelan-Goodinson et al92 also found a strong relationship between post-TBI depression, anxiety, and outcome. Furthermore, as with any potentially disabling condition, individuals

Inhibitors,research,lifescience,medical with TBI report a variety of symptoms in different domains (discouragement, frustration, fatigue, anxiety, etc). Not all of these symptoms will rise to Inhibitors,research,lifescience,medical the level of a disorder. However, constellations of symptoms that are consistent and sustained over time (usually weeks), and that are of sufficient severity to interfere with social or occupational function or quality of life, are legitimately

considered disorders. The consistent observation that individuals who sustain a TBI have higher base rates of psychopathology before injury also suggests that there is a reciprocal interaction: psychopathology predisposes to TBI, and TBI in turn predisposes the individual to develop psychiatric disorders. Although Inhibitors,research,lifescience,medical the link between TBI and psychiatric disorders holds for many conditions, the relationship of TBI to PTSD and dementia are worth additional comment. Relationship to PTSD Recent conflicts in Iraq and Afghanistan have focused attention on the relationship Edoxaban between psychological and biomcchanical trauma particularly in military populations (eg, see refs 93-95). Several recent studies highlight their complex interaction. Hoge et al96 found that higher rates of Iraq war returnees reporting a TBI with loss of consciousness met criteria for PTSD, relative to those reporting only altered mental status, other injuries, and or no injury. Much of the variance across these groups with respect to physical health http://www.selleckchem.com/products/PF-2341066.html outcomes and symptoms could be accounted for by the presence of PTSD and/or depression.

This review found one trial that documented the effect of physical activity in people aged 40–65 on longer-term falls, suggesting a small, non-significant reduction of the risk of falls in people who exercised (Pereira et al 1998). Given that long-term falls was not one of the primary outcomes of the study by Pereira and colleagues, these findings should be interpreted with care, as the trial might have been selleck chemical underpowered to find a difference in the rate of long-term falls. Recently, a trial (Lawton et al 2008) on the effectiveness of

Modulators advice to increase physical activity levels was conducted among women aged 40–74. This trial found that, although effective in increasing the physical activity levels, advice to be more physically active only did not produce improvements in clinical or biological outcomes such as blood pressure, weight, levels of cholesterol, insulin, or blood glucose levels (Lawton et al 2008) and led to only a slight increase in the rate of short-term falls (32%) when compared to usual care (25%) (Lawton et al 2008). As the aim of the present review was to assess the effectiveness of physical activity programs, trials on advice to increase or promote physical activity such as the former, were RG7204 purchase not included. However the relationship between physical activity and falls needs further investigation. Some information about

the longer-term effects of physical activity can also be obtained from observational studies. There 3-mercaptopyruvate sulfurtransferase is a substantial risk of bias in such studies. It is likely that other factors (such as chronic disease, psychological factors) could be associated with both falls and physical activity and could confound any apparent protective effect of physical activity on falls.

However, statistical techniques can be used to attempt to control for these factors. For example, an analysis of data from the prospective large-scale Australian Longitudinal Study on Women’s Health study included over 8000 healthy women aged 70–75 and controlled for likely confounders. This analysis found that women who were more active experienced fewer falls and fall-related fractures (Heesch et al 2008). Women who were highly active were 36% less likely to have a fall in the subsequent three years (Heesch et al 2008). Similar analyses in large studies in other countries have found that highly active people are less likely to develop disability (Boyle et al 2007, Nusselder et al 2008). The amount of physical activity required to prevent future falls is not clear from this review. However, as changes in muscle structure and muscular co-ordination (balance) are required, it is suggested that a more specific ACSM or World Health Organization guideline about strength and balance training be used to guide practice rather than a more general aim of increasing physical activity. In conclusion, this review found that muscle strength, balance, and endurance can clearly be improved by physical activity in people aged 40–65.

Thus preterm infants appear to be potentially more vulnerable to repeated procedural pain/stress, due to immature capacity to differentiate nociceptive from tactile input. Together with low tactile threshold and sensitization to repeated touch in preterm neonates, the finding that evoked responses were widespread across the brain coalesces with other studies that have found that diaper change can induce as much biobehavioral response as blood collection under certain conditions.52 Stress of handling and procedures in the NICU is associated with changes

in brain structure and function.1,34,48 There appears to be Rapamycin cost tremendous capacity for Inhibitors,research,lifescience,medical studies combining behavioral and physiological measures concurrently with EEG or NIRS, to address the impact of procedures in a multidimensional pain response reflecting many levels of the CNS. At school-age, there Inhibitors,research,lifescience,medical appears to be only one study that has examined brain reactivity to painful stimuli in children born

preterm. On functional magnetic resonance imaging (fMRI) at age 9–14 years, children born preterm displayed greater activation in the somatosensory cortex and other brain regions, compared to children born full-term with or without early hospitalization.53 Research Inhibitors,research,lifescience,medical to address understanding the effects of neonatal pain in very preterm infants as well as other infants exposed to NICU care, on responses in the brain evoked by touch and pain later in childhood and adolescence, is likely to receive a lot more attention in the future. As well, relationships between brain activation and self-report of pain need to be evaluated. Importantly, Inhibitors,research,lifescience,medical programs

designed to recognize infant stress cues and provide supportive care, compared to standard practice, are associated with improved brain maturation. The Neonatal Individualized Developmental Care and Assessment Program (NIDCAP), compared to standard care of preterm neonates, led to more mature coherence between frontal and other brain regions on Inhibitors,research,lifescience,medical EEG and better neurobehavioral function.1 Parent training in the NICU to help reduce stress in their very preterm infant was associated with better cerebral white Bay 11-7085 matter microstructure, maturation, and connectivity on MRI at term-equivalent age,48 and with increased frontal EEG brain activity during sleep,54 compared to infants that received standard care. In a longitudinal cohort of preterm infants followed from birth to school-age, Grunau, Ribary, and colleagues examined whether neonatal pain is associated with functional brain activity later in childhood. They found that greater cumulative neonatal pain-related stress was associated with altered spontaneous oscillatory brain activity (indexed as the ratio of gamma to alpha activity using magnetoencephalography) at age 7 years.

“More than 100 million people in Asia were living with diabetes mellitus in 2007 (Chan et al 2009). In Singapore, the ageing of the population together with the rise in rates of obesity and sedentary lifestyle parallelled the rise of Type 2 diabetes mellitus. click here The prevalence of Type 2 diabetes mellitus in 2004 was

8.2% in adults aged 18 to 69 years (Lim et al 2004). Diabetes doubles the risk of cardiovascular disease (Wang et al 2005) and, in Singapore, one-third of patients developing cardiovascular disease were reported to have underlying Type 2 diabetes mellitus (Lee et al 2001). Singaporeans have a higher percentage of body fat for the same body mass index as Caucasians (Deurenberg-Yap et al 2003), and those with Type 2 diabetes mellitus have significantly higher body mass index and

waist:hip ratio compared with healthy adults (Lim et al 2004). Aerobic exercise is known to reduce weight and maintain good glycaemic control, and thus reduce the risk of cardiovascular disease among diabetic patients (Lee et al 2001). Studies involving exercise as a therapeutic intervention in patients with Type 2 diabetes mellitus have focused primarily on aerobic training (Boule et al 2003, Snowling and Hopkins 2006). The beneficial effects of aerobic training on the metabolic profile include reduced HbA1c, lowered blood pressure and resting heart rate, improved cardiac output and oxygen extraction, favorable lipid profile, and reduction of RO4929097 order weight and waist circumference (Albright et al 2000, Boule et al 2001, Lim et al 2004, Sigal et al 2007, Snowling and Hopkins 2006, Tresierras and Balady 2009). In spite of the reported beneficial effects of aerobic exercise on cardiovascular and metabolic parameters, adoption of aerobic activities may be difficult for some patients with Type 2 diabetes mellitus, especially those who are older

and obese (Willey and Singh 2003). In the last decade, there has been increasing interest in the role of resistance exercise in the management of diabetes as it appears to improve insulin sensitivity (Tresierras and Balady 2009). While the American College of Sports Medicine recommended resistance exercise at least twice a week (Albright et al 2000), the American Diabetes Association recommended others it three times per week. These recommendations were based primarily on findings from two trials comparing aerobic and resistance exercise (Cauza et al 2005, Dunstan et al 2002). Libraries However, neither study attempted to make the modes of exercise comparable in intensity or duration. Furthermore, some studies have included both modes in the same intervention arm (Cuff et al 2003, Maiorana et al 2000), thus limiting our ability to compare the two. Other data suggest that progressive resistance exercise has benefits in the treatment of Type 2 diabetes (Neil and Ronald 2006, Irvine and Taylor 2009).

Because of her hypokalemia, she received 40 meq potassium chloride and normal saline during the first hour of treatment. The routine treatment of DKA was started with 10 units

of regular insulin per hour. During the first 4 hours of treatment, her alkalosis progressed to a pH of 7.64. Face mask was applied to retain Co2 and lower blood pH. Her nausea, vomiting, and abdominal pain subsided after 5 hours of treatment and her serum ketone became negative after 8 hours. She was able to eat after 14 hrs and 2 days later she was discharged on insulin (twice daily). She was Inhibitors,research,lifescience,medical in a good general condition at discharge. Because of her undetectable c-peptide level, she was diagnosed as a case of pancreas transplant failure and her immunosuppressant drugs were discontinued. Discussion

Our patient had strongly positive serum ketone, but at the same time her blood pH was in the alkalemic range of 7.5. The mean plasma pH in other reported cases has been 7.55.2 This alkalemic pH Inhibitors,research,lifescience,medical in our patient can be explained by the presence of mixed acid-base disturbance. The calculated anion gap was 27 mmol/L which was 11 mmol/L higher than normal. If the patient had pure metabolic acidosis, the serum bicarbonate was expected to drop to 11 Inhibitors,research,lifescience,medical meq/L. The serum bicarbonate in our patient had failed to decrease which signifies the presence of concomitant metabolic alkalosis.3,4 In our patients, repeated vomiting and the effect of a high dose of methylprednisolone were two causes for metabolic alkalosis. Dabrafenib order hypokalemia can also maintain alkalosis and contribute to the overall clinical condition. The other acid-base abnormality in our patient was respiratory alkalosis. The Inhibitors,research,lifescience,medical patient’s serum bicarbonate was 25 meq/L. Moreover, the expected arterial PaCo2 is 40 mmHg, but our patient had an arterial PaCo2 of 32 mmHg, reflecting Inhibitors,research,lifescience,medical the presence of respiratory alkalosis. Pain and anxiety can be the causes of respiratory alkalosis in this patient.5 As expected, treatment of DKA led to the progression of alkalosis, but with

therepletion of water and electrolytes, plasma pH gradually returned normal. In most previously reported cases the main causes of DKA were hypovlemia because of vomiting and use of diuretics,6 and alcohol ingestion.7 Gastroparesis is also associated with recurrent ketoalkalosis.8 Use of diuretics and repeated also vomiting result in electrolyte depletion and hypovolemia, leading to bicarbonate reabsorption and alkalosis.3,6 Two cases of endogenous Cushing’s syndrome because of adrenal adenoma and ectopic adrenocorticotropin (ACTH) production with DKA have also been reported.2 Our case is the first reported case associated with glucocorticoid pulse therapy. Excess endogenous or exogenous glucocorticoids can promote H+ excretion from the kidneys by their effect on mineralocorticoid receptor and contribute to alkalosis.9 Respiratory alkalosis, as in our patient, has also been implicated as a contributing factor.

32 Finally, a poor overall response rate of schizophrenic symptoms in both groups was determined, with no significant differences concerning positive, negative,

or depressive symptoms. An important, limitation, however, involves the small sample size of 24 patients. A recent pilot study, however, provided some evidence that treatment with aripiprazole, a partial dopamine agonist with high affinity for both dopamine D2 and D3 receptors, might, possibly lower both the desire for and the use of cocaine in these patients.35 As a result, significant, decreases in craving for cocaine, strikingly fewer positive urine screens, and significant Inhibitors,research,lifescience,medical decreases in psychotic symptoms suggest, that aripiprazole may be of benefit. Anyway, these findings need a cautious interpretation Inhibitors,research,lifescience,medical with respect to the small sample size of 10 subjects, and should be reassessed anyway using a double-blind, randomized comparison study design. Intervention and aim of treatment Since Talazoparib schizophrenia and substance misuse have been determined to be closely interdependent, a dual diagnosis – treatment of schizophrenia and drug abuse is needed. Currently, research is focusing on a range of psychological strategies such as family intervention,

skills training, cognitive therapy, or development of substance refusal.36,37 Most of these psychological Inhibitors,research,lifescience,medical interventions are based on cognitive behavioral procedures. To date, there is a growing body of evidence that motivational enhancement interventions, which tend to alter drug use and refine skills, may be a feasible first-line intervention for substance abuse in early psychosis.38 Kavanagh et al2 recommend a division into at least, three groups: schizophrenic patients with mild substance-related problems, who benefit, from brief, motivational Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical interventions;

those patients who profit from social support and more extensive skills training; and finally those patients with severe cognitive deficits who need ongoing environmental structure and social support, for an indefinite period. However, the main focus of treatment for these patients consists in stabilization of psychotic symptoms, hostility, and agitation. Several new antipsychotic medications, such as risperidone, clozapine, or olanzapine, have been introduced, and appear to be at least as effective as the typical antipychotics. Bumetanide Furthermore, strong evidence have been provided that these “atypical” neuroleptics produce fewer extrapyramidal side effects (RPS) and a lower risk of tardive dyskinesia.39 As already discussed, patients who develop RPS or neuroleptic dysphoria may use substances in order to alleviate these side effects. Therefore some atypical antipsychotics may be of benefit.40 Currently, most of the data on comorbidity are based on clozapine, which has been found to be approximately equally effective in treatment-resistant patients with and without substance abuse.
