ABSTRACT

BACKGROUND: This study investigates the use of biparametric magnetic resonance imaging (bpMRI) as primary opportunistic screening for prostate cancer (PCa) without using a prostate-specific antigen (PSA) cut-off. OBJECTIVE: The primary endpoint was to assess the efforts and effectiveness of identifying 20 participants with clinically significant prostate cancer (csPCa) using bpMRI. DESIGN, SETTING, AND PARTICIPANTS: Biopsy-naïve men aged over 45 yr were included. All participants underwent 3 Tesla bpMRI, PSA, and digital rectal examination (DRE). Targeted-only biopsy was performed in participants with Prostate Imaging Reporting and Data System (PI-RADS) ≥3. Men with negative bpMRI but suspicious DRE or elevated PSA/PSA density had template biopsies. Preintended protocol adjustments were made after an interim analysis for PI-RADS 3 lesions: no biopsy and follow-up MRI after 6 mo and biopsy only if lesions persisted or upgraded. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Biopsy results underwent a comparison using Fisher's exact test and univariable logistic regression to identify prognostic factors for positive biopsy. RESULTS AND LIMITATIONS: A total of 229 men were enrolled in this study, of whom 79 underwent biopsy. Among these men, 77 displayed suspicious PI-RADS lesions. PCa was detected in 29 participants (12.7%), of whom 21 had csPCa (9.2%). Biparametric MRI detected 21 csPCa cases, while PSA and DRE would have missed 38.1%. Protocol adjustment led to a 54.6% biopsy reduction in PI-RADS 3 lesions. Overall, in this cohort of men with a median PSA value of 1.26 ng/ml, 10.9 bpMRI scans were needed to identify one participant with csPCa. A major limitation of the study is the lack of a control cohort undergoing systematic biopsies. CONCLUSIONS: Opportunistic screening utilising bpMRI as a primary tool has higher sensitivity in detecting csPCa than classical screening methods. PATIENT SUMMARY: Screening with biparametric magnetic resonance imaging (bpMRI) and targeted biopsy identified clinically significant prostate cancer in every 11th man, regardless of the prostate-specific antigen (PSA) levels. Preselecting patients based on PSA >1 ng/ml and a positive family history of prostate cancer, as well as other potential blood tests may further improve the effectiveness of bpMRI in this setting.

ABSTRACT

BACKGROUND: It has been shown that the Stockholm3 test decreases overdetection of prostate cancer (PCa) while retaining the ability to detect clinically significant PCa (csPCa) in a Swedish population. However, the test includes potentially population-specific testing of single-nucleotide polymorphisms and has yet not been validated outside Scandinavia. OBJECTIVE: To assess the performance of the Stockholm3 test in discriminating csPCa in a Central European cohort undergoing prostate biopsy (PBx). DESIGN, SETTING, AND PARTICIPANTS: This prospective multicenter validation study was conducted from August 2020 to September 2022 at two centers in Switzerland and one center in Germany. The study involved 342 men undiagnosed with PCa who were scheduled for PBx after prostate-specific antigen (PSA) testing and subsequent magnetic resonance imaging (MRI) of the prostate. Before PBx, participants had a blood sample taken for Stockholm3 testing. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was the accuracy of the Stockholm3 test in detecting csPCa (International Society of Urological Pathology grade group [GG] ≥2) according to the area under the receiver operating characteristic curve (AUC), sensitivity, and specificity, and the clinical consequences of using the model. RESULTS AND LIMITATIONS: The Stockholm3 test with a cutoff of 11% for csPCa detection had sensitivity of 92.3% (95% confidence interval [CI] 86.9-95.9%), specificity of 32.6% (95% CI 26.0-39.8%), a positive predictive value of 53.2% (95% CI 47.0-59.2%), and a negative predictive value of 83.6% (95% CI 73-91.2%). It showed superior discrimination for csPCa (AUC 0.77, 95% CI 0.72-0.82) in comparison to PSA (AUC 0.66, 95% CI 0.61-0.72; p < 0.001). Using a Stockholm3 cutoff of 11%, PBx could have been omitted for 73 men (21.0%), and 12/154 (8%) csPCa and 2/72 (2.8%) GG >2 cases would have been missed. Limitations include population selection bias. CONCLUSIONS: Our results show favorable clinical outcomes for the blood-based Stockholm3 biomarker test in a Central European patient cohort. PATIENT SUMMARY: The Stockholm3 blood test shows better accuracy in predicting prostate cancer than the more common PSA (prostate-specific antigen) test.

ABSTRACT

BACKGROUND: ß3-AR (ß3-adrenergic receptor) stimulation improved systolic function in a sheep model of systolic heart failure (heart failure with reduced ejection fraction [HFrEF]). Exploratory findings in patients with New York Heart Association functional class II HFrEF treated with the ß3-AR-agonist mirabegron supported this observation. Here, we measured the hemodynamic response to mirabegron in patients with severe HFrEF. METHODS: In this randomized, double-blind, placebo-controlled trial we assigned patients with New York Heart Association functional class III-IV HFrEF, left ventricular ejection fraction <35% and increased NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels to receive mirabegron (300 mg daily) or placebo orally for a week, as add on to recommended HF therapy. Invasive hemodynamic measurements during rest and submaximal exercise at baseline, 3 hours after first study dose and repeated after 1 week's treatment were obtained. Predefined parameters for analyses were changes in cardiac- and stroke volume index, pulmonary and systemic vascular resistance, heart rate, and blood pressure. RESULTS: We randomized 22 patients (age 66±11 years, 18 men, 16, New York Heart Association functional class III), left ventricular ejection fraction 20±7%, median NT-proBNP 1953 ng/L. No significant changes were seen after 3 hours, but after 1 week, there was a significantly larger increase in cardiac index in the mirabegron group compared with the placebo group (mean difference, 0.41 [CI, 0.07-0.75] L/min/BSA; P=0.039). Pulmonary vascular resistance decreased significantly more in the mirabegron group compared with the placebo group (-1.6 [CI, -0.4 to -2.8] Wood units; P=0.02). No significant differences were seen during exercise. There were no differences in changes in heart rate, systemic vascular resistance, blood pressure, or renal function between groups. Mirabegron was well-tolerated. CONCLUSIONS: Oral treatment with the ß3-AR-agonist mirabegron for 1 week increased cardiac index and decreased pulmonary vascular resistance in patients with moderate to severe HFrEF. Mirabegron may be useful in patients with worsening or terminal HF. REGISTRATION: URL: https://www. CLINICALTRIALS: gov; Unique identifier: 2016-002367-34.

ABSTRACT

The seven mammalian FXYD proteins associate closely with α/ß heterodimers of Na+/K+-ATPase. Most of them protect the ß1 subunit against glutathionylation, an oxidative modification that destabilizes the heterodimer and inhibits Na+/K+-ATPase activity. A specific cysteine (Cys) residue of FXYD proteins is critical for such protection. One of the FXYD proteins, FXYD3, confers treatment resistance when overexpressed in cancer cells. We developed two FXYD3 peptide derivatives. FXYD3-pep CKCK retained the Cys residue that can undergo glutathionylation and that is critical for protecting the ß1 subunit against glutathionylation. FXYD3-pep SKSK had all Cys residues mutated to Serine (Ser). The chemotherapeutic doxorubicin induces oxidative stress, and suppression of FXYD3 with siRNA in pancreatic- and breast cancer cells that strongly express FXYD3 increased doxorubicin-induced cytotoxicity. Exposing cells to FXYD3-pep SKSK decreased co-immunoprecipitation of FXYD3 with the α1 Na+/K+-ATPase subunit. FXYD3-pep SKSK reproduced the increase in doxorubicin-induced cytotoxicity seen after FXYD3 siRNA transfection in pancreatic- and breast cancer cells that overexpressed FXYD3, while FXYD3-pep CKCK boosted the native protein's protection against doxorubicin. Neither peptide affected doxorubicin's cytotoxicity on cells with no or low FXYD3 expression. Fluorescently labeled FXYD3-pep SKSK was detected in a perinuclear distribution in the cells overexpressing FXYD3, and plasmalemmal Na+/K+-ATPase turnover could not be implicated in the increased sensitivity to doxorubicin that FXYD3-pep SKSK caused. FXYD peptide derivatives allow rapid elimination or amplification of native FXYD protein function. Here, their effects implicate the Cys residue that is critical for countering ß1 subunit glutathionylation in the augmentation of cytotoxicity with siRNA-induced downregulation of FXYD3.

ABSTRACT

BACKGROUND: Cardio- and cerebrovascular events such as myocardial infarction (MI), stroke and transient ischemic attack (TIA) are leading causes of death and disability and have also been associated with poor mental outcomes. In addition, cardio- and cerebrovascular events may pose the risk of experiencing a sudden traumatic occurrence of symptoms during ictus and thus contribute to high rates of PTSD as well as high rates of subsequent depression and anxiety. Moreover, MI, TIA and stroke survivors with PTSD, depressive and anxiety symptoms may have poorer health-related quality of life (HRQoL) and poorer disease prognosis than patients who do not develop psychiatric symptoms after ictus. However, data on the prevalence of PTSD, anxiety and depression, as well as the HRQoL, coping strategies and potential risk factors for development of PTSD in these patients, are rare. METHODS: In an exploratory, descriptive study we interviewed 112 patients (54 MI, 18 TIA, 40 stroke; mean age: 69.5 years, 55.4% males) from three general physician practices and used psychometric self-assessment tools to determine the occurrence of PTSD and psychosomatic comorbidity, anxiety and depression and to assess HRQoL and coping strategies. We evaluated disease severity and compared the patient groups to each other. Moreover, we assessed psychological outcome differences between patients with or without PTSD after ictus. RESULTS: The prevalence of PTSD after MI, TIA and stroke was 23.2%. The patients who developed PTSD had higher rates of depression, anxiety and maladaptive coping as well as reduced HRQoL. Adaptive coping was positively related to better mental HRQoL and negatively related to anxiety and depression. Disease severity of MI, TIA and stroke was not related to PTSD, depression, anxiety or physical HRQoL. CONCLUSIONS: Experiencing MI, TIA or stroke means confronting a life-threatening event for those affected and, therefore, these can be regarded as traumatic events. Cerebral and cardiovascular events increase the risk of developing chronic PTSD with subsequent increased depression and anxiety and reduced HRQoL. These findings emphasize the need for early screening and diagnosis of PTSD in somatically ill patients, which should be followed by specialized treatment, as PTSD hampers overall (somatic) disease prognosis.

ABSTRACT

Cariprazine is a highly effective antipsychotic medication of the latest generation. Due to its special receptor profile with D2/D3 partial agonism and high D3 affinity, the use of cariprazine is particularly justified in negative psychotic symptomatic and cardiac prestressed patients or in patients with weight management problems. In this case series, two cases and the outcomes during the switch to cariprazine treatment under these conditions are described.

ABSTRACT

Sex differences in jealousy responses to sexual and emotional infidelity are robust in samples of heterosexual adults, especially in more gender egalitarian nations. However, investigations of when and how these differences develop have been scant. We applied two forced choice infidelity scenarios in a large community sample of high school students (age 16-19, N = 1266). In line with previous findings on adults using the forced choice paradigm, adolescent males found the sexual aspect of imagined infidelity more distressing than adolescent females did. Nevertheless, there was no effect of age on the jealousy responses, and age did not moderate the sex difference. There were neither any effects of three covariates (having had first sexual intercourse, being in a committed romantic relationship, and sociosexuality), neither as markers of pubertal maturation nor as psychosocial environmental stimuli. Future research needs to investigate even younger samples in order to specify at what age the sex difference in jealousy responses emerges.

ABSTRACT

Rates of post-traumatic stress symptoms, anxiety and depression are increased in patients having experienced a transient ischemic attack (TIA) or stroke several months ago. However, data of psychiatric symptoms in the acute phase within the first days after ictus are lacking. In 20 patients with stroke and 33 patients with TIA we assessed disease severity by means of the NIHSS, levels of depression and anxiety by HADS, PTSD-like symptoms by PC-PTSD, quality of life (HrQoL) by SF-12, and coping style by brief COPE Inventory within the first 5 days after ictus. NIHSS on admission was lower in patients with TIA (0 ± 1) than in patients with stroke (3 ± 2, p < 0.001). HADS depression score was significantly higher in patients with stroke (7.0 ± 4.5) than in patients with TIA (4.9 ± 4.0). HADS anxiety score, HrQoL and coping styles were similar between TIA and stroke patients (p > 0.05). 5 and 3 of 33 TIA patients as well as 4 and 3 of 20 stroke patients had at least 11 points in the HADS anxiety and depression score respectively (p = 0.001). 2 of 33 TIA patients and 2 of 20 stroke patients had more than 2 points in the PC-PTSD (p = 0.646). We did not find consistent correlations between the NIHSS and the psychometric parameters. Within the first five days after patients having experienced a TIA or stroke PTSD-like, anxious and depressive symptoms are more common than in the general population. As the acute psychological status after ictus is predictive for psychiatric comorbidity years later physicians should pay attention and adequately treat psychiatric symptoms already in the acute phase of stroke.Trial Registration: German Clinical Trials Register, DRKS00021730, https://www.drks.de/drks_web/navigate.do?navigationId=trial.HTML&TRIAL_ID=DRKS00021730 , registered 05/19/2020- Retrospectively registered.

ABSTRACT

CONTEXT: Reduced Na+-K+ pump activity is widely reported in preeclampsia and may be caused by a reversible oxidative modification that is a novel pathological feature of preeclampsia. OBJECTIVE: This work aims to determine whether ß 1 subunit (GSS-ß 1) protein glutathionylation of the Na+-K + pump occurs in preeclampsia. METHODS: The GSS-ß1 of the Na+-K+ pump and its subunit expression in human placentas were compared between women with healthy pregnancies and women with preeclampsia. Human placental samples of pregnant women with preeclampsia (n = 11, mean gestational age 36.5 weeks) were used to examine the GSS-ß 1 of the Na+-K+ pump, compared to healthy pregnancies (n = 11, mean gestational age 39 weeks).The potential pathogenetic role of GSS-ß 1-mediated Na+-K+ pump dysfunction in preeclampsia was investigated. RESULTS: Protein expression of the ß 1 subunit was unchanged in placentas from women with preeclampsia vs those with normotensive pregnancies. Preeclamptic placentas had a significantly increased GSS-ß 1 of the Na+-K+ pump compared to those from healthy pregnancies, and this was linked to a decrease in α 1/ß 1 subunit coimmunoprecipitation. The cytosolic p47phox nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) oxidase subunit and its coimmunoprecipitation with the α 1 Na+-K+ pump subunit was increased in preeclamptic placentas, thus implicating NADPH oxidase-dependent pump inhibition. CONCLUSIONS: The high level of ß 1 pump subunit glutathionylation provides new insights into the mechanism of Na+-K+ pump dysfunction in preeclampsia.

ABSTRACT

INTRODUCTION: The Comparison of Methylphenidate and Psychotherapy in adult ADHD Study (COMPAS) was a prospective, randomized multicenter clinical trial, comparing methylphenidate (MPH) with placebo (PLAC) in combination with cognitive behavioral group psychotherapy (GPT) or individual clinical management (CM) over the period of 1 year. Here, we report results on treatment safety. METHODS: MPH and PLAC were flexibly dosed. Among 433 randomized patients, adverse events (AEs) were documented and analyzed on an "as received" basis during week 0-52. Electrocardiogram data were recorded at baseline and week 24. RESULTS: Comparing 205 patients who received ≥1 dose of MPH with 209 patients who received PLAC, AEs occurring significantly more frequently in the MPH group were decreased appetite (22 vs. 3.8%), dry mouth (15 vs. 4.8%), palpitations (13 vs. 3.3%), gastrointestinal infection (11 vs. 4.8%), agitation (11 vs. 3.3%), restlessness (10 vs. 2.9%), hyperhidrosis, tachycardia, weight decrease (all 6.3 vs. 1.9%), depressive symptom, influenza (both 4.9 vs. 1.0%), and acute tonsillitis (4.4 vs. 0.5%). Syncope occurred significantly more often in the PLAC group (2.4 vs. 0%). Clinically relevant ECG changes occurred very rarely in both groups. Serious AEs were rare and without a significant group difference. The comparison of 206 patients treated with GPT versus 209 patients who received CM revealed no major differences. Serious AE classified as psychiatric occurred in 5 cases in the CM group and in 1 case in the GPT group. CONCLUSION: In this so far longest-running clinical trial, methylphenidate treatment was safe and well-tolerated.

ABSTRACT

Toxoplasma gondii (T. gondii) has a high worldwide prevalence and an underestimated impact on neuropsychiatric disorders. Previous studies related T. gondii to disorders associated with the dysfunctional dopaminergic system. However, an association between T. gondii infection and adult attention-deficit/hyperactivity disorder (ADHD) has not yet been studied. In a sex- and age-matched case-control study, we investigated the seropositivity, serointensity, and avidity of latent T. gondii infection in adult ADHD patients and examined the influence of those variables on the symptomatology of ADHD. Of 140 participants, 20.0% were seropositive for anti-T. gondii IgG and 0% for anti-T. gondii IgM. T. gondii seropositivity was associated with 2.8-fold increase in the odds of ADHD in a confounder-adjusted multivariable analysis. Age and consumption of raw/undercooked meat were confirmed as significant predictors of T. gondii seropositivity. Multiple linear regression analysis of self-rated ADHD-related symptom severity in all participants revealed a significant association with T. gondii seropositivity, elevated IgG titers (serointensity), and stronger anti-T. gondii IgG avidity. Overall symptom severity was increased in seropositive ADHD patients compared to seronegative subjects with ADHD. In particular, hyperactivity was significantly associated with serointensity. We conclude that there is a high rate of T. gondii seropositivity in adults with ADHD. Additionally, our results suggest a clinical impact of latent T. gondii infection on ADHD-related symptoms in a serointensity- and avidity-dependent manner.

ABSTRACT

BACKGROUND: Abnormally high cytosolic Na+ concentrations in advanced heart failure impair myocardial contractility. Stimulation of the membrane Na+-K+ pump should lower Na+ concentrations, and the ß3 adrenoceptor (ß3 AR) mediates pump stimulation in myocytes. We examined if ß3 AR-selective agonists given in vivo increase myocyte Na+-K+ pump activity and reverse organ congestion in severe heart failure (HF). METHODS: Indices for HF were lung-, heart-, and liver: body weight ratios and ascites after circumflex coronary artery ligation in rabbits. Na+-K+ pump current, Ip, was measured in voltage-clamped myocytes from noninfarct myocardium. Rabbits were treated with the ß3 AR agonists CL316,243 or ASP9531, starting 2 weeks after coronary ligation. RESULTS: Coronary ligation caused ascites in most rabbits, significantly increased lung-, heart-, and liver: body weight ratios, and decreased Ip relative to that for 10 sham-operated rabbits. Treatment with CL316,243 for 3 days significantly reduced lung-, heart-, and liver: body weight ratios and prevalence of ascites in 8 rabbits with HF relative to indices for 13 untreated rabbits with HF. It also increased Ip significantly to levels of myocytes from sham-operated rabbits. Treatment with ASP9531 for 14 days significantly reduced indices of organ congestion in 6 rabbits with HF relative to indices of 6 untreated rabbits, and it eliminated ascites. ß3 AR agonists did not significantly change heart rates or blood pressures. CONCLUSIONS: Parallel ß3 AR agonists-induced reversal of Na+-K+ pump inhibition and indices of congestion suggest pump inhibition is a useful target for treatment with ß3 AR agonists in congestive HF.

ABSTRACT

PURPOSE: Kidney transplantation (KT) is the treatment of choice for end-stage chronic kidney disease (CKD) and is well known to improve the clinical outcome of patients. However, the impact of KT on comorbid psychological symptoms, particularly depression and anxiety, is less clear, and recipients of living-donor (LD) organs may have a different psychological outcome from recipients of dead-donor (DD) organs. DESIGN/METHODOLOGY/APPROACH: In total, 152 patients were included and analyzed using a cross-sectional design. Of these patients, 25 were pre-KT, 13 were post-KT with a LD transplant and 114 were post-KT with a DD transplant. The patients were tested for a variety of psychometric outcomes using the Hospital Anxiety and Depression Scale, the 12-Item Short Form Health Survey (assessing physical and mental health-related quality of life), the Resilience Scale, the Coping Self-Questionnaire and the Social Support Questionnaire. FINDINGS: The mean age of the patients was 51.25 years and 40 per cent of the patients were female. As expected, the post-KT patients had significantly better scores on the physical component of the Short Form Health Survey than the pre-KT patients, and there were no significant differences between the two post-KT groups. There were no significant differences among the groups in any of the other psychometric outcome parameters tested, including anxiety, depression and the mental component of health-related quality of life. RESEARCH LIMITATIONS/IMPLICATIONS: KT and the origin of the donor organ do not appear to have a significant impact on the psychological well-being of transplant patients with CKD. Although the diagnosis and early treatment of psychological symptoms, such as depression and anxiety, remain important for these patients, decisions regarding KT, including the mode of transplantation, should not be fundamentally influenced by concerns about psychological impairments at the population level. ORIGINALITY/VALUE: CKD is a serious condition involving profound impairment of the physical and psychological well-being of patients. KT is considered the treatment of choice for most of these patients. KT has notable advantages over dialysis with regard to the long-term physical functioning of the renal and cardiovascular system and increases the life expectancy of patients. However, the data on the improvement of psychological impairments after KT are less conclusive.

ABSTRACT

A growing body of literature indicates a potential role for physical exercise in the treatment of attention deficit hyperactivity disorder (ADHD). Suggested effects include the reduction of ADHD core symptoms as well as improvements in executive functions. In the current review, we provide a short overview on the neurophysiological mechanisms assumed to underlie the beneficial effects of exercise. Further, we review the current evidence from experimental studies regarding both acute exercise and long-term interventions in ADHD. While the positive effects observed after acute aerobic exercise are promising, very few well-designed long-term intervention studies have been conducted yet. Moreover, although exercise effects have not yet been studied in borderline personality disorder (BPD), in the end of this paper we derive hypotheses why exercise could also be beneficial for this patient population.

ABSTRACT

Concerning the diagnosis and therapy of pain syndromes, standardized descriptions similar to those used in the examination of psychopathological findings via the system produced by the AMDP ("Arbeitsgemeinschaft für Methodik und Dokumentation in der Psychiatrie", i. e., the working group establishing standardized methodology and documentation within psychiatry) are still lacking. Therefore, the authors of this article have founded a working group to establish standardized methodology and documentation for symptoms and signs associated with pain, although not at a diagnosis-specific level, in order to promote standardization in the documentation of pain and rating of the symptoms associated with a given set of medical results. This article presents a system for documenting the symptoms and signs associated with pain globally and independently of the diagnosis (Structured Pain Assessment System) with nomenclature that is inspired by the AMDP system. The objective of this working group is to develop documentation for a uniform multidimensional pain assessment (with defined terminology) that serves as a comparable and unified standard in the field.

ABSTRACT

Vagus nerve stimulation (VNS) is an established tool in the psychiatric armamentarium for patients with therapy-resistant depression (TRD) with response rates of approximately 60%. So far, VNS is titrated slowly during ambulatory in-office visits. Thus, antidepressive effects can be expected after approximately six months. We report our experiences with a rapid dosing regime (RDR) with titration start shortly after VNS-implantation. We retrospectively analysed data of six patients with TRD who received VNS. Stimulation parameters were evaluated with regard to clinical side effects, heart rates (HR) and blood pressures (BP). Depressive symptoms were measured by Montgomery-Asberg Depression Rating Scale (MADRS) one week before and three months after implantation of the VNS. All patients received first stimulation between one and four days after surgery. We elevated output current using 0.25 mA titration steps. We increased output current between one and four days after the last titration. All patients received 1.0 mA output current after eight to 14 days post-surgery. HR and BP remained stable in all patients. All side effects were mild and temporary. MADRS scores were significantly lower three months after VNS-implantation (24 ±â€¯8) than one week before VNS-implantation (42 ±â€¯4; p = 0.028). The therapeutic range of VNS-parameters for antidepressive effect was reached quicker without finding increased numbers of side effects. Consequently, by using RDR the antidepressive effect of VNS-therapy for patients with TRD could be reached earlier than using slow titration. Our presented RDR might be able to significantly shorten the "clinical effect gap" due to the neurobiological and titration-related latency.

Coercive measures in psychiatry are used as a last resort if other means to avert imminent danger failed. Our case shows, that even if all precautions were taken complications may arise: We report about a young man, who had been restrained. After the belts had been partly loosened, he again became extremely aggressive. When the restraints had to be tightened he could grab and swallow the Segufix®-Metal Pin.

ABSTRACT

Importance: Knowledge about the long-term effects of multimodal treatment in adult attention-deficit/hyperactivity disorder (ADHD) is much needed. Objective: To evaluate the long-term efficacy of multimodal treatment for adult ADHD. Design, Setting, and Participants: This observer-masked, 1.5-year follow-up of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a prospective, multicenter randomized clinical trial, compared cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) and methylphenidate (MPH) with placebo (2 × 2 factorial design). Recruitment started January 2007 and ended August 2010, and treatments were finalized in August 2011 with follow-up through March 2013. Overall, 433 adults with ADHD participated in the trial, and 256 (59.1%) participated in the follow-up assessment. Analysis began in November 2013 and was completed in February 2018. Interventions: After 1-year treatment with GPT or CM and MPH or placebo, no further treatment restrictions were imposed. Main Outcomes and Measures: The primary outcome was change in the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score from baseline to follow-up. Secondary outcomes included further ADHD rating scale scores, observer-masked ratings of the Clinical Global Impression scale, and self-ratings of depression on the Beck Depression Inventory. Results: At follow-up, 256 of 433 randomized patients (baseline measured in 419 individuals) participated. Of the 256 patients participating in follow-up, the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score was assessed for 251; the mean (SD) baseline age was 36.3 (10.1) years; 125 patients (49.8%) were men; and the sample was well-balanced with respect to prior randomization (GPT and MPH: 64 of 107; GPT and placebo: 67 of 109; CM and MPH: 70 of 110; and CM and placebo: 55 of 107). At baseline, the all-group mean ADHD Index of Conners Adult ADHD Rating Scale score was 20.6, which improved to adjusted means of 14.2 for the GPT arm and 14.7 for the CM arm at follow-up with no significant difference between groups (difference, -0.5; 95% CI, -1.9 to 0.9; P = .48). The adjusted mean decreased to 13.8 for the MPH arm and 15.2 for the placebo arm (difference, -1.4; 95% CI, -2.8 to -0.1; P = .04). As in the core study, MPH was associated with a larger reduction in symptoms than placebo at follow-up. These results remained unchanged when accounting for MPH intake at follow-up. Compared with participants in the CM arm, patients who participated in group psychotherapy were associated with less severe symptoms as measured by the self-reported ADHD Symptoms Total Score according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) of Conners Adult ADHD Rating Scale (AMD, -2.1; 95% CI, -4.2 to -0.1; P = .04) and in the subscale of reducing pure hyperactive symptoms, measured via the Diagnostic Checklist for the diagnosis of ADHD in adults (AMD, -1.3; 95% CI, -2.8 to 0.1; P = .08). Regarding the Clinical Global Impression scale assessment of effectiveness, the difference between GPT and CM remained significant at follow-up (odds ratio, 1.63; 95% CI, 1.03-2.59; P = .04). No differences were found for any comparison concerning depression as measured with the Beck Depression Inventory. Conclusions and Relevance: Results from COMPAS demonstrate a maintained improvement in ADHD symptoms for adults 1.5 years after the end of a 52-week controlled multimodal treatment period. The results indicate that MPH treatment combined with GPT or CM provides a benefit lasting 1.5 years. Confirming the results of the core study, GPT was not associated with better results regarding the primary outcome compared with CM. Trial Registration: isrctn.org Identifier: ISRCTN54096201.
