Response to semaglutide of non-drinker subjects with type 2 diabetes

BACKGROUND

Metabolic dysfunction-associated Steatotic Liver Disease (MASLD) displays a worse prognosis in subjects with type 2 diabetes (T2D); effective treatments are, so far, scanty. Semaglutide showed efficacy in improving steatohepatitis. We longitudinally observed a MASLD cohort of T2D subjects starting semaglutide, to detect an improvement of non-invasive surrogates of steatosis and fibro-inflammatory liver involvement, evaluating the role of mild alcohol consumption.

PATIENTS AND METHODS

In 62 overweight/obese T2D subjects with MASLD (36 non-drinker and 26 mild alcohol consumers), anthropometric, bio-humoral and transient elastography (TE) data were collected before (T0) and after an average time of 6.4 month (T1) from injective semaglutide prescription. Circulating levels of hormones (GIP, GLP-1, glucagon, insulin) and inflammatory markers (TNFα, MCP-1, IL-18, IL-10) were measured. Steatotic and necro-inflammatory liver involvement was evaluated with FibroScan controlled attenuation parameter (CAP) and liver stiffness (LS), respectively.

RESULTS

Significant (p < 0.006) T0-T1 reductions of BMI, waist circumference, fasting glucose, and HbA1c were observed. AST (-10 ± 3 IU/L), ALT (-18 ± 5 IU/L), GGT (-33 ± 15 IU/L), CAP (-25 ± 8 dB/m) and LS (-0.8 ± 0.4 kPa) were reduced, too. GLP-1 increased (+ 95.9 pM, p < 0.0001) and IL-18 was reduced (-46.6 pg/ml, p = 0.0002). After adjustment for confounders, CAP improving was only related to GLP-1 increase (ß=-0.437, p = 0.0122). Mild alcohol intake did not influence these relations.

CONCLUSION

Use of semaglutide in subjects with T2D and MASLD is associated with a significant decline of liver steatosis and necroinflammation proxies; mild alcohol assumption did not exert any influence. An independent effect of GLP-1 raise was observed on reduction of steatosis, irrespective of alcohol consumption.

DEep LearnIng-based QuaNtification of epicardial adipose tissue predicts MACE in patients undergoing stress CMR

BACKGROUND AND AIMS

This study investigated the additional prognostic value of epicardial adipose tissue (EAT) volume for major adverse cardiovascular events (MACE) in patients undergoing stress cardiac magnetic resonance (CMR) imaging.

METHODS

730 consecutive patients [mean age: 63 ± 10 years; 616 men] who underwent stress CMR for known or suspected coronary artery disease were randomly divided into derivation (n = 365) and validation (n = 365) cohorts. MACE was defined as non-fatal myocardial infarction and cardiac deaths. A deep learning algorithm was developed and trained to quantify EAT volume from CMR. EAT volume was adjusted for height (EAT volume index). A composite CMR-based risk score by Cox analysis of the risk of MACE was created.

RESULTS

In the derivation cohort, 32 patients (8.7 %) developed MACE during a follow-up of 2103 days. Left ventricular ejection fraction (LVEF) < 35 % (HR 4.407 [95 % CI 1.903-10.202]; p<0.001), stress perfusion defect (HR 3.550 [95 % CI 1.765-7.138]; p<0.001), late gadolinium enhancement (LGE) (HR 4.428 [95%CI 1.822-10.759]; p = 0.001) and EAT volume index (HR 1.082 [95 % CI 1.045-1.120]; p<0.001) were independent predictors of MACE. In a multivariate Cox regression analysis, adding EAT volume index to a composite risk score including LVEF, stress perfusion defect and LGE provided additional value in MACE prediction, with a net reclassification improvement of 0.683 (95%CI, 0.336-1.03; p<0.001). The combined evaluation of risk score and EAT volume index showed a higher Harrel C statistic as compared to risk score (0.85 vs. 0.76; p<0.001) and EAT volume index alone (0.85 vs.0.74; p<0.001). These findings were confirmed in the validation cohort.

CONCLUSIONS

In patients with clinically indicated stress CMR, fully automated EAT volume measured by deep learning can provide additional prognostic information on top of standard clinical and imaging parameters.

MRI pattern characterization of cerebral cardioembolic lesions following atrial fibrillation ablation

Background

Recognizing etiology is essential for treatment and secondary prevention of cerebral ischemic events. A magnetic resonance imaging (MRI) pattern suggestive of an embolic etiology has been described but, to date, there are no uniformly accepted criteria.

Aim

The purpose of the study is to describe MRI features of ischemic cerebral lesions occurring after transcatheter ablation of atrial fibrillation (AF).

Methods

A systematic review and meta-analysis of studies performing brain imaging investigations before and after AF transcatheter ablation was performed. The incidence of cerebral ischemic lesions after AF transcatheter ablation was the primary endpoint. The co-primary endpoints were the prevalence of the different neuroimaging features regarding the embolic cerebral ischemic lesions.

Results

A total of 25 studies, encompassing 3,304 patients, were included in the final analysis. The incidence of ischemic cerebral lesions following AF transcatheter ablation was 17.2% [95% confidence interval (CI) 12.2%-23.8%], of which a minimal fraction was symptomatic [0.60% (95% CI 0.09%-3.9%)]. Only 1.6% of the lesions (95% CI 0.9%-3.0%) had a diameter >10 mm, and in 20.5% of the cases the lesions were multiple (95% CI 17.1%-24.4%). Brain lesions were equally distributed across the two hemispheres and the different lobes; cortical location was more frequent [64.0% (95% CI 42.9%-80.8%)] while the middle cerebral artery territory was the most involved 37.0% (95% CI 27.3-48.0).

Conclusions

The prevailing MRI pattern comprises a predominance of small (<10 mm) cortical lesions, more prevalent in the territory of the middle cerebral artery.

Myocardial Bridging: Review on the Role of Coronary Computed Tomography Angiography

Myocardial bridging (MB) is a congenital coronary anomaly in which a segment of a coronary artery, most frequently the left anterior descending artery, deviates from its epicardial route by passing through the myocardium. The advent of cardiac computed tomography angiography (CCTA), equipped with its multiplane and three-dimensional functionalities, has notably enhanced the ability to identify MBs. Furthermore, novel post-processing methods have recently emerged to extract functional insights from anatomical evaluations. MB is generally considered a benign entity with very good survival rates; however, there is an increasing volume of evidence that certain MB characteristics may be associated with cardiovascular morbidity. This review is intended to depict the diagnostic and prognostic role of CCTA in the MB context.

Quantification of extracellular volume with cardiac computed tomography in patients with dilated cardiomyopathy

BACKGROUND

Cardiac computed tomography (CCT) was recently validated to measure extracellular volume (ECV) in the setting of cardiac amyloidosis, showing good agreement with cardiovascular magnetic resonance (CMR). However, no evidence is available with a whole-heart single source, single energy CT scanner in the clinical context of newly diagnosed left ventricular dysfunction. Therefore, the aim of this study was to test the diagnostic accuracy of ECVCCT in patients with a recent diagnosis of dilated cardiomyopathy, having ECVCMR as the reference technique.

METHODS

39 consecutive patients with newly diagnosed dilated cardiomyopathy (LVEF <50%) scheduled for clinically indicated CMR were prospectively enrolled. Myocardial segment evaluability assessment with each technique, agreement between ECVCMR and ECVCCT, regression analysis, Bland-Altman analysis and interclass correlation coefficient (ICC) were performed.

RESULTS

Mean age of enrolled patients was 62 ​± ​11 years, and mean LVEF at CMR was 35.4 ​± ​10.7%. Overall radiation exposure for ECV estimation was 2.1 ​± ​1.1 ​mSv. Out of 624 myocardial segments available for analysis, 624 (100%) segments were assessable by CCT while 608 (97.4%) were evaluable at CMR. ECVCCT demonstrated slightly lower values compared to ECVCMR (all segments, 31.8 ​± ​6.5% vs 33.9 ​± ​8.0%, p ​< ​0.001). At regression analysis, strong correlations were described (all segments, r ​= ​0.819, 95% CI: 0.791 to 0.844). On Bland-Altman analysis, bias between ECVCMR and ECVCCT for global analysis was 2.1 (95% CI: -6.8 to 11.1). ICC analysis showed both high intra-observer and inter-observer agreement for ECVCCT calculation (0.986, 95%CI: 0.983 to 0.988 and 0.966, 95%CI: 0.960 to 0.971, respectively).

CONCLUSIONS

ECV estimation with a whole-heart single source, single energy CT scanner is feasible and accurate. Integration of ECV measurement in a comprehensive CCT evaluation of patients with newly diagnosed dilated cardiomyopathy can be performed with a small increase in overall radiation exposure.

Stress Echocardiography in Italian Echocardiographic Laboratories: A Survey of the Italian Society of Echocardiography and Cardiovascular Imaging

Background

The Italian Society of Echography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand the volumes of activity, modalities and stressors used during stress echocardiography (SE) in Italy.

Methods

We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved through an electronic survey based on a structured questionnaire, uploaded on the SIECVI website.

Results

Data were obtained from 228 echocardiographic laboratories, and SE examinations were performed in 179 centers (80.6%): 87 centers (47.5%) were in the northern regions of Italy, 33 centers (18.4%) were in the central regions, and 61 (34.1%) in the southern regions. We annotated a total of 4057 SE. We divided the SE centers into three groups, according to the numbers of SE performed: <10 SE (low-volume activity, 40 centers), between 10 and 39 SE (moderate volume activity, 102 centers) and ≥40 SE (high volume activity, 37 centers). Dipyridamole was used in 139 centers (77.6%); exercise in 120 centers (67.0%); dobutamine in 153 centers (85.4%); pacing in 37 centers (21.1%); and adenosine in 7 centers (4.0%). We found a significant difference between the stressors used and volume of activity of the centers, with a progressive increase in the prevalence of number of stressors from low to high volume activity (P = 0.033). The traditional evaluation of regional wall motion of the left ventricle was performed in all centers, with combined assessment of coronary flow velocity reserve (CFVR) in 90 centers (50.3%): there was a significant difference in the centers with different volume of SE activity: the incidence of analysis of CFVR was significantly higher in high volume centers compared to low - moderate - volume (32.5%, 41.0% and 73.0%, respectively, P < 0.001). The lung ultrasound (LUS) was assessed in 67 centers (37.4%). Furthermore for LUS, we found a significant difference in the centers with different volume of SE activity: significantly higher in high volume centers compared to low - moderate - volume (25.0%, 35.3% and 56.8%, respectively, P < 0.001).

Conclusions

This nationwide survey demonstrated that SE was significantly widespread and practiced throughout Italy. In addition to the traditional indication to coronary artery disease based on regional wall motion analysis, other indications are emerging with an increase in the use of LUS and CFVR, especially in high-volume centers.

Cardiac computed tomography: from anatomy to function

Ischaemic heart disease (IHD) is one of the world's leading causes of morbidity and mortality. Likewise, the diagnosis and risk stratification of patients with coronary artery disease (CAD) have always been based on the detection of the presence and extent of ischaemia by physical or pharmacological stress tests with or without the aid of imaging methods (e.g. exercise stress, test, stress echocardiography, single-photon emission computed tomography, or stress cardiac magnetic resonance). These methods show high performance to assess obstructive CAD, whilst they do not show accurate power to detect non-obstructive CAD. The introduction into clinical practice of coronary computed tomography angiography, the only non-invasive method capable of analyzing the coronary anatomy, allowed to add a crucial piece in the puzzle of the assessment of patients with suspected or chronic IHD. The current review evaluates the technical aspects and clinical experience of coronary computed tomography in the evaluation of atherosclerotic burden with a special focus about the new emerging application such as functional relevance of CAD with fractional flow reserve computed tomography (CT)-derived (FFRct), stress CT perfusion, and imaging inflammatory makers discussing the strength and weakness of each approach.

Organization and Activity of Italian Echocardiographic Laboratories: A Survey of the Italian Society of Echocardiography and Cardiovascular Imaging

Background

The Italian Society of Echocardiography and Cardiovascular Imaging (SIECVI) conducted a national survey to understand better how different echocardiographic modalities are used and accessed in Italy.

Methods

We analyzed echocardiography laboratory activities over a month (November 2022). Data were retrieved via an electronic survey based on a structured questionnaire, uploaded on the SIECVI website.

Results

Data were obtained from 228 echocardiographic laboratories: 112 centers (49%) in the northern, 43 centers (19%) in the central, and 73 (32%) in the southern regions. During the month of observation, we collected 101,050 transthoracic echocardiography (TTE) examinations performed in all centers. As concern other modalities there were performed 5497 transesophageal echocardiography (TEE) examinations in 161/228 centers (71%); 4057 stress echocardiography (SE) examinations in 179/228 centers (79%); and examinations with ultrasound contrast agents (UCAs) in 151/228 centers (66%). We did not find significant regional variations between the different modalities. The usage of picture archiving and communication system (PACS) was significantly higher in the northern (84%) versus central (49%) and southern (45%) centers (P < 0.001). Lung ultrasound (LUS) was performed in 154 centers (66%), without difference between cardiology and noncardiology centers. The evaluation of left ventricular (LV) ejection fraction was evaluated mainly using the qualitative method in 223 centers (94%), occasionally with the Simpson method in 193 centers (85%), and with selective use of the three-dimensional (3D) method in only 23 centers (10%). 3D TTE was present in 137 centers (70%), and 3D TEE in all centers where TEE was done (71%). The assessment of LV diastolic function was done routinely in 80% of the centers. Right ventricular function was evaluated using tricuspid annular plane systolic excursion in all centers, using tricuspid valve annular systolic velocity by tissue Doppler imaging in 53% of the centers, and using fractional area change in 33% of the centers. When we divided into cardiology (179, 78%) and noncardiology (49, 22%) centers, we found significant differences in the SE (93% vs. 26%, P < 0.001), TEE (85% vs. 18%), UCA (67% vs. 43%, P < 0001), and STE (87% vs. 20%, P < 0.001). The incidence of LUS evaluation was similar between the cardiology and noncardiology centers (69% vs. 61%, P = NS).

Conclusions

This nationwide survey demonstrated that digital infrastructures and advanced echocardiography modalities, such as 3D and STE, are widely available in Italy with a notable diffuse uptake of LUS in the core TTE examination, a suboptimal diffusion of PACS recording, and conservative use of UCA, 3D, and strain. There are significant differences between northern and central-southern regions and echocardiographic laboratories that pertain to the cardiac unit. This inhomogeneous distribution of technology represents one of the main issues that must be solved to standardize the practice of echocardiography.

Quality of residential facilities in Italy: satisfaction and quality of life of residents with schizophrenia spectrum disorders

BACKGROUND

Recovery and human rights promotion for people with Schizophrenia Spectrum Disorders (SSDs) is fundamental to provide good care in Residential Facilities (RFs). However, there is a concern about rehabilitation ethos in RFs. This study aimed to investigate the care quality of Italian RFs, the quality of life (QoL) and care experience of residents with SSD.

METHODS

Fourty-eight RFs were assessed using a quality assessment tool (QuIRC-SA) and 161 residents with SSD were enrolled. Seventeen RFs provided high intensity rehabilitation (SRP1), 15 medium intensity (SRP2), and 16 medium-low level support (SRP3). Staff-rated tools measured psychiatric symptoms and psychosocial functioning; user-rated tools assessed QoL and satisfaction with services. RFs comparisons were made using ANOVA and Chi-squared.

RESULTS

Over two-thirds patients (41.5 y.o., SD 9.7) were male. Seventy-six were recruited from SRP1 services, 48 from SRP2, and 27 from SRP3. The lowest QuIRC-SA scoring was Recovery Based Practice (45.8%), and the highest was promotion of Human Rights (58.4%). SRP2 had the lowest QuIRC-SA ratings and SRP3 the highest. Residents had similar psychopathology (p = 0.140) and functioning (p = 0.537). SRP3 residents were more employed (18.9%) than SRP1 (7.9%) or SRP2 (2.2%) ones, and had less severe negative symptoms (p = 0.016) and better QoL (p = 0.020) than SRP2 residents. There were no differences in the RF therapeutic milieu and their satisfaction with care.

CONCLUSIONS

Residents of the lowest supported RFs in Italy had less severe negative symptoms, better QoL and more employment than others. The lowest ratings for Recovery Based Practice across all RFs suggest more work is needed to improve recovery.

438 Appearances are deceiving

Aims

Mitral valve prolapse (MVP) is frequently found in the population (3% prevalence). MVP prognosis is generally benign; however, malignant arrhythmias and increased risk of arrhythmic sudden cardiac death (0.2% to 0.4% per year) was described in patients, usually female, mostly affected by bileaflet myxomatous disease, mid-systolic click, ripolarization abnormalities in the inferior leads, and complex ventricular arrhythmias with polymorphic/right bundle branch block morphology, without significant regurgitation. The actual burden, risk stratification, and treatment of the so-called arrhythmic MVP are unknown.

Methods

Z.T. is a 32 years old woman who was admitted to the Emergency Department (ED) with left arm and face paraesthesia. She also reported having suffered from migraine and hypertension a few days earlier. ECG: normal sinus rhythm, no ripolarization abnormalities. CT and MRI were executed to rule out cerebral ischaemic events and both resulted negative. No SCD was reported in the anamnesis and the patient denied syncopal and pre-syncopal episodes. Z.T. had undergone cardiologic examination for tachycardia 2 years before the present events, during her second pregnancy (she produced no documentation to this effect). No chronic therapy. Low blood pressure at home. Due to the patient’s cardiologic history, ECG monitoring was performed, evidencing frequent premature ventricular beats (PVBs), some couples, and triplets. Cardiologic evaluation was requested. On Echocardiogram: Normal bi-ventricular function. Bileaflet mitral valve prolapse with myxomatous degeneration. Minimal valve regurgitation. Mitral annulus disjunction. TE echocardiogram: no PFO. Nadolol 20 mg was prescribed and after 24 h of observation the patient was discharged, scheduling Holter ECG, cardiac MRI and arrhythmologic evaluation.

Results

One month later, the patient reported intolerance to nadolol due to hypotension and pre-syncopal episodes during postural changes. Holter ECG revealed: polymorphic PVBs (2009), couples (383), triplets (40). Cardiac MRI: mitral valve prolapse (11 mm), mitral annulus disjunction (8mm) systolic curling (3mm). No LGE. No oedema. Nadolol was discontinued and substituted with bisoprolol 2.5 mg. Physical activity was discouraged; Ergometric test and Holter ECG were ordered under treatment with bisoprolol. The Ergometric test revealed reduced extrasystolia during physical effort, isolated PVBs and some couples during recovery. Holter ECG revealed continuing isolated PVBs (980) and some couples (37). No complex arrhythmia.

Conclusion

Z.T. is affected by an arrhythmic MVP syndrome characterized by complex PVBs, mitral annular disjunction, and systolic curling, which have been described by pathological and cardiac magnetic resonance studies in sudden death victims. However, Z.T. is asymptomatic: no ECG ripolarization abnormalities at rest and good response to medical therapy with β-blockers.

Our patient strategy was conservative and we decided to follow up with trimestral cardiologic evaluation and Holter ECG. Further research is needed to best identify high-risk patients and suggest treatments aimed to prevent sudden death.

148 ECG abnormalities in COVID-19 pneumonia: acute pericarditis, silent cad, or both? A case report

Aims We report the case of a hypertensive 70 year-old man, who presented to the Emergency Department (ED) with fever, dry cough, malaise, dyspnoea. A nasopharyngeal swab for SARS-CoV-2 test was done, being positive.

Methods and results Chest TC demonstrated ground glass bilateral pneumonia. Laboratory test showed WBC 10680/mmc, CRP 20 mg/l, TnT 0.03 ng/l, NTproBNP 147 ng/l. The liver and kidney function were within normal values. ECG was normal. He was treated with high flow oxygen (cPAP), enoxaparin, dexamethasone, doxycycline. After an initial improvement, dyspnoea got worse in 8th day, with the evidence of a new rise of inflammatory markers (PCR 95 mg/l, IL6 49 pg/ml) and the clinical new onset of cardiac rubbings on medical examination. The ECG revealed a sinus rhythm with T wave inversion everywhere. TnT remained normal. Echocardiography revealed a normal ventricular function, without segmentary alterations, absence of valvular disease. A mild pericardial effusion was evidenced, without signs of tamponade. We treated the patient with tocilizumab, after exclusion of other active infective foci. The clinical response was good, the patient was progressively weaned by oxygen and he was discharged asymptomatic. After 15 days, for ECG alterations persistence, despite no signs of ACS, a Coronary TC was done and a subcritical multivessel coronary artery disease was demonstrated: a subcritical IVA stenosis and a calcific MO.

Conclusions In conclusion we report a successful treatment of COVID pneumonia likely complicated by acute pericarditis, and we observe that in these patients hypoxemia and cytochine storm possibly bring out silent vascular diseases, otherwise neglected.

Left atrial appendage morphology at transesophageal echocardiography: how to improve reproducibility?

BACKGROUND

Left atrial appendage (LAA) morphology, investigated by computed tomography and magnetic resonance imaging, has proved to relate to the risk of cerebrovascular events in patients with atrial fibrillation (AF). The aim of the present study was to assess reproducibility of transesophageal echocardiography (TEE) imaging in describing LAA morphology.

METHODS

Two-hundred consecutive patients referred for TEE were enrolled. In the first group of 47 (23.5%) patients LAA morphology was analyzed by conventional TEE and described as ChickenWing, Windsock, Cactus or Cauliflower. In the second group of 153 (76.5%) patients, instead, a 3D-Xplane diagnostic algorithm was performed to stratify LAA morphology as linear (ChickenWing) or complex (Windsock/Cactus and Cauliflower). Interobserver variability within three independent readers was assessed in both groups of patients and stratified by operator's experience and training. In a subgroup of 19 (12.4%) patients, the agreement of LAA morphology description by 3D-Xplane diagnostic algorithm was compared to cardiac magnetic resonance.

RESULTS

By conventional TEE the agreement among operators on LAA morphology classification was poor (ρ<0.13). The 3D-XPlane diagnostic algorithm, significantly increased interobserver agreement up to ρ=0.32 within all readers and up to ρ=0.82 among the experienced and specifically trained operators. LAA morphology description in this latter group provided strong agreement with cardiac magnetic resonance (up to ρ=0.77).

CONCLUSIONS

LAA morphology assessment is challenging by conventional TEE. To improve reproducibility, the use of the 3D-Xplane technique combined with a specific diagnostic algorithm and training of the operators is fundamental.

Subclinical Left Ventricular Dysfunction in Severe Obesity and Reverse Cardiac Remodeling after Bariatric Surgery

Aim:

Obesity is associated with an increased cardiovascular risk. This study aimed to assess the role of echocardiography in the early detection of subclinical cardiac abnormalities in a cohort of obese patients with a preserved ejection fraction (EF) undergoing bariatric surgery.

Methods and Results:

Forty consecutive severely obese patients (body mass index≥35 kg/m2) referring to our center for bariatric surgery were enrolled in this prospective cohort study. Despite a baseline EF of 61% ± 3%, almost half patients (43%) had a systolic dysfunction (SD) defined as global longitudinal strain (GLS)>−18%, and most of them (60%) had left ventricular hypertrophy (LVH) or concentric remodeling (CR). At 10-months after surgery, body weight decreased from 120 ± 15 kg to 83 ± 12 kg, body mass index from 44 ± 5 kg/m² to 31 ± 5 kg/m² (both P < 0.001). Septal and left ventricular posterior wall thickness decreased respectively from 10 ± 1 mm to 9 ± 1 mm (P = 0.004) and from 10 ± 1 mm to 9 ± 1 mm (P = 0.007). All systolic parameters improved: EF from 61% ± 3% to 64% ± 3% (P = 0.002) and GLS from −17% ± 2% to −20% ± 1% (P < 0.001). Epicardial fat thickness reduction (from 4.7 ± 1 mm to 3.5 ± 0.7 mm, P < 0.001) correlated with the reduction of left atrial area (P < 0.001 R = 0.35) and volume (P = 0.02 R = 0.25). Following bariatric surgery, we observed a reduced prevalence of LVH/CR (before 60%, after 22%, P = 0.001) and a complete resolution of preclinical SD (before 43%, after 0%, P < 0.001). Moreover, a postoperative reduction of at least 30 kg correlated with regression of septal hypertrophy (P < 0.001).

Conclusions:

Obese patients candidate to bariatric surgery have an high prevalence of preclinical SD and LVH/CR, early detectable with echocardiography. Bariatric surgery is associated with reverse cardiac remodeling; it might also have a preventive effect on atrial fibrillation occurrence by reducing its substrate.

Efficacy of oral trazodone slow release following intravenous administration in depressed patients: a naturalistic study

BACKGROUNDS

Up to date, no studies in literature assessed the efficacy of a treatment schedule including i.v. trazodone followed by its oral administration. In light of this lack of evidence, the aim of the present study was to evaluate the efficacy and tolerability of trazodone, administered first i.v. and then orally in a sample of Major Depressive Disorder (MDD) patients.

METHODS

Thirty four patients underwent i.v. administration of trazodone (75-100 mg in 250 mL of saline) for 1 week. During the second week, oral extended-release formulation (150-300 mg per day) was added to the i.v. administration. Finally, extended-release trazodone was orally administration at doses of 150-300 mg per day. Psychometric scales were performed at baseline (T0), after 2 weeks (T1), 6 weeks (T2), after 3 months (T3), and 6 months (T4).

RESULTS

The total sample included 34 subjects (14 males and 20 females). There was a statistically significant decrease in Hamilton Depression Rating Scale total scores from T0 to T1 (t=9.06; df=33), from T1 to T2 (t=4.96; df=29), from T2 to T3 (t=4.08; df=19), and from T3 to T4 (t=2.25; df=19); in Hamilton Anxiety Rating Scale total scores from T0 to T1 (t=8.79; df=33) and from T1 to T2 (t=5.61; df=29); in Montgomery-Asberg Depression Rating Scale total scores from T0 to T1 (t=9.30; df=33), from T1 to T2 (t=5.69; df=29), and from T2 to T3 (t=3.16; df=19).

CONCLUSIONS

This finding confirms previous results on depression with concomitant anxiety symptoms: focusing on trazodone prolonged-release formulation, available data documented its efficacy in MDD.

THE USE OF LONG-ACTING ANTIPSYCHOTICS FOR THE MANAGEMENT OF AGGRESSIVENESS IN SCHIZOPHRENIA: A CLINICAL OVERVIEW

Aggressive behaviour represents a challenge in the treatment of patients with schizophrenia, being often associated with clinical predictors of severity of illness such as poor insight, psychotic re-exacerbation, concomitant substance misuse or comorbidity with personality disorders. As psychotic relapses and consequent risk of aggressive behaviour are often associated with a poor compliance, purpose of the present manuscript is to give an overview of the available data about the use of depot antipsychotics for the management of violence in patients with schizophrenia. A research in the main database sources has been conducted to identify relevant papers about the topic. Few studies (most of them retrospective and with small sample sizes) have investigated the effectiveness of depot antipsychotic for the treatment of aggressive behaviour in schizophrenia. Aripiprazole depot appears to be promising for the management of aggressive behaviour of subjects with schizophrenia, however data about its efficacy in the long-term are absent and lack of evidence prevents the recommendation of this compound for the treatment of aggressiveness in subjects affected by schizophrenia. In addition, there is not sufficient evidence to conclude that a specific depot antipsychotic may have a better efficacy on aggressive behaviour of patients affected by schizophrenia. Prospective comparative studies (e.g. with oral clozapine and aripiprazole depot) are needed to assess the real clinical advantage of the use of depot antipsychotic versus oral alternatives for the prevention of violent behaviour in schizophrenia.

Paliperidone Long-Acting Plasma Level Monitoring and a New Method of Evaluation of Clinical Stability

The second generation long-acting antipsychotics can be a pharmacologic strategy, both in the early phase of illness and in the case of low compliance. The aim of the study was to evaluate the clinical efficacy and tolerability of one monthly injection of paliperidone palmitate (PP1M), paliperidone plasma levels (PLs), and the clinical outcome.

21 outpatients, affected by Schizophrenia or Schizoaffective Disorder, were recruited. PP1M started with 150 mg on day 1 and 100 mg on day 8. Following patients were given a dosage ranging from 50 mg to 150 mg every 28 days. At baseline, and then monthly, patients were clinically evaluated.

BPRS and PANSS total score showed a statistically significant decrease from T2 (after 2 months) to T12 (after 12 months). The PLs steady-state was approximatively reached after the fifth injection (T4).

All the patients showed a clinical stabilization: BPRS and PANSS scores showed a significant improvement from T2. PLs data seems to suggest the initial possibility of an oral supplementation, although clinical evaluation demonstrated no relapse during the study.

Results of Cryoablation for Atrial Fibrillation Concomitant With Video-Assisted Minimally Invasive Mitral Valve Surgery

Interest in minimally invasive video-assisted mitral valve surgery (MIMVS) is rapidly growing. Data on concomitant atrial fibrillation (AF) ablation to MIMVS are still lacking. The present study investigates the long-term results of AF cryoablation concomitant to MIMVS. From October 2006-September 2014, 68 patients with mitral valve disease (age 65.9 ± 11.1 years, 34 men out of 68 patients, Euroscore log 5.4 ± 4.5) and drug-resistant AF underwent MIMVS via right minithoracotomy and concomitant left-sided AF endocardial cryoablation (Cryoflex Medtronic, Minneapolis, MN). Patients were independently followed up by cardiological outpatient visits and underwent electrophysiological study when indicated. In total, 44 out of 68 patients (64.7%) underwent mitral valve repair and 8 patients (11.8%) also received concomitant tricuspid valve surgery. One procedure was electively converted to full sternotomy (1.5%). Total clamp time was 97.6 ± 22.8 minutes. In March 2015, 60 patients were alive and completed the follow-up after a mean of 3.4 ± 2.0 years following the procedure. In all, 48 patients (80%) presented sinus rhythm throughout the whole follow-up. Freedom from AF was respectively 95%, 87%, and 72% at 1, 3, and 5 years, respectively. We recorded 2 pacemaker implants (3.3%). A total of 3 patients suffered symptomatic recurrences (2 atypical atrial flutter and 1 atrial fibrillation) and underwent transcatheter ablation-all the 3 patients remained in stable sinus rhythm for the remaining follow-up. In conclusions, given the favorable long-term sinus rhythm maintenance rates of concomitant cryoablation, MIMVS can also be offered to patients with symptomatic AF. AF transcatheter ablation may easily avoid further symptomatic recurrences.

Structural and metabolic differentiation between bipolar disorder with psychosis and substance-induced psychosis: An integrated MRI/PET study

BACKGROUND

Bipolar disorder (BD) may be characterized by the presence of psychotic symptoms and comorbid substance abuse. In this context, structural and metabolic dysfunctions have been reported in both BD with psychosis and addiction, separately. In this study, we aimed at identifying neural substrates differentiating psychotic BD, with or without substance abuse, versus substance-induced psychosis (SIP) by coupling, for the first time, magnetic resonance imaging (MRI) and positron emission tomography (PET).

METHODS

Twenty-seven BD type I psychotic patients with (n=10) or without (n=17) substance abuse, 16 SIP patients and 54 healthy controls were enrolled in this study. 3T MRI and 18-FDG-PET scanning were acquired.

RESULTS

Gray matter (GM) volume and cerebral metabolism reductions in temporal cortices were observed in all patients compared to healthy controls. Moreover, a distinct pattern of fronto-limbic alterations were found in patients with substance abuse. Specifically, BD patients with substance abuse showed volume reductions in ventrolateral prefrontal cortex, anterior cingulate, insula and thalamus, whereas SIP patients in dorsolateral prefrontal cortex and posterior cingulate. Common alterations in cerebellum, parahippocampus and posterior cingulate were found in both BD with substance abuse and SIP. Finally, a unique pattern of GM volumes reduction, with concomitant increased of striatal metabolism, were observed in SIP patients.

CONCLUSIONS

These findings contribute to shed light on the identification of common and distinct neural markers associated with bipolar psychosis and substance abuse. Future longitudinal studies should explore the effect of single substances of abuse in patients at the first-episode of BD and substance-induced psychosis.

Anatomic relationship between left coronary artery and left atrium in patients undergoing atrial fibrillation ablation

BACKGROUND

Atrial fibrillation transcatheter ablation (TCA) is, within available atrial fibrillation rhythm control strategies, one of the most effective. To potentially improve ablation outcome in case of recurrent atrial fibrillation after a first procedure or in presence of structural myocardial disease, isolation of the pulmonary veins may be associated with extensive lesions within the left atrium. To avoid rare, but potentially life-threatening, complications, thorough knowledge and assessment of left atrium anatomy and its relation to structures in close proximity are, therefore, mandatory. Aim of the present study is to describe, by cardiac computed tomography, the anatomic relationship between aortic root, left coronary artery and left atrium in patients undergoing atrial fibrillation TCA.

METHODS AND RESULTS

The cardiac computed tomography scan of 21 patients affected by atrial fibrillation was elaborated to segment left atrium, aortic root and left coronary artery from the surrounding structures and the following distances measured: left atrium and aortic root; left atrium roof and aortic root; left main coronary artery and left atrium; circumflex artery and left atrium appendage; and circumflex artery and mitral valve annulus. Above all, the median distance between left atrium and aortic root (1.9, 1.5-2.1 mm), and between circumflex artery and left atrium appendage ostium (3.0, 2.1-3.4 mm) were minimal (≤3 mm). None of measured distances significantly varied between patients presenting paroxysmal versus persistent atrial fibrillation.

CONCLUSION

The anatomic relationship between left atrium and coronary arteries is extremely relevant when performing atrial fibrillation TCA by extensive lesions. Therefore, at least in the latter case, preablation imaging should be recommended to avoid rare, but potentially life-threatening, complications with the aim of an as well tolerated as possible procedure.

Duloxetine in elderly major depression disorder: effectiveness and drug plasma level evaluation

OBJECTIVE

The aim of this open-label naturalistic study was to assess clinical outcomes and the predictive value of duloxetine plasma levels in major depressive disorder in the elderly.

METHODS

This naturalistic, open-label design involved 35 outpatients aged between 65 and 87 years. Duloxetine plasma levels were collected in 24 patients after the first month. Patients were evaluated using 21-item Hamilton Rating Scales for Depression, Hamilton Rating Scales for Anxiety, the Clinical Global Impression Severity, Mini Mental State Examination, Cumulative Illness Rating Scale, Barthel Index and Beck's Depression Inventory.

RESULTS

Duloxetine plasma levels at T2 ranged from 4.9 to 201.9 ng/mL without a significant correlation between duloxetine dose and plasma levels. A significant improvement in mean 21-item Hamilton Rating Scales for Depression total scores at T2,T3, T4, T9 and T12 and a progressive significantly decrease of the mean Hamilton Rating Scales for Anxiety scores from T3 to T12 were observed.

CONCLUSIONS

The levels of duloxetine in plasma do not correlate with a greater clinical improvement, indeed appear to adversely affect the improvement of the Beck Depression Inventory and Hamilton Rating Scales for Anxiety. This could be explained by an increase in side effects that may aggravate the discomfort felt by the patient. Copyright © 2016 John Wiley & Sons, Ltd.

Cabergoline can induce mania with psychotic features in bipolar I disorder: a case report

Up to date, only a small evidence of psychosis induced by cabergoline is available in literature. Herein, the case of a 34-year-old bipolar patient treated with cabergoline has been described. Cabergoline is generally a safe and effective method of reducing prolactin levels and it may be associated with psychiatric side effects, including psychotic features.

"Long-acting" olanzapine in maintenance therapy of schizophrenia: A study with plasma levels

INTRODUCTION

This prospective study was performed to evaluate clinical efficacy and tolerability of olanzapine long-acting injection (OLZ-LAI) and the relation between OLZ plasma level (PL) and the clinical outcome in maintenance therapy of schizophrenia.

MATERIAL AND METHODS

Twenty-five chronic schizophrenic outpatients with age ranging from 18 to 65 years were included in this 9-month study. Patients were given a dosage of either 210 or 300 or 405 mg of OLZ-LAI every 28 days. Patients were evaluated at baseline and every four weeks by Brief Psychiatric Rating Scale (BPRS) and Positive and Negative Symptom Scale (PANSS); at the same time, PL of OLZ was determined. The metabolic profile (aspartate aminotransferase, alanine aminotransferase, high-density lipoprotein, low-density lipoprotein, total cholesterol, and glucose levels) was analyzed every two months.

RESULTS

BPRS and total PANSS showed a statistically significant improvement from T2 with a clinical stabilization of psychopathological picture. PL ranged from 4.0 to 78.9 ng/ml (mean 20.59 ng/ml ± 14.66 standard deviation). The coefficient of variation of PLs was related to clinical stabilization. No post-injection delirium sedation syndrome occurred.

CONCLUSIONS

Our data reveal the efficacy of OLZ-LAI in maintenance treatment of schizophrenia at lower dosages also in comparison with that of oral therapy. OLZ-LAI seems to be useful for guaranteeing constant PL of the drug. A lesser variation of PL was the most predictable factor associated with maintenance of clinical benefit.

Percutaneous implantation of a second device in patients with residual right-to-left shunt after patent foramen ovale closure

INTRODUCTION

The management of patients with residual right-to-left shunt (rRLS) after percutaneous patent foramen ovale (PFO) closure is debated. The aim of this study was to define the incidence of moderate-to-large rRLS and to report the feasibility, safety and long-term clinical outcome of transcatheter closure of rRLS.

METHODS AND RESULTS

From June 2000 to March 2013, 322 subjects underwent percutaneous PFO closure. In 39 patients (12.1%) with moderate-to-large rRLS on transcranial Doppler (TCD) and/or transesophageal echocardiogram a second cardiac catheterization was performed with the aim of completing the closure. A second closure device was implanted in 21 patients (53.8%). In the remaining 18 (46.2%), a second device was not delivered for the following reasons: in 13 (72.2%) no residual passage could be crossed, in 5 (27.8%) the residual shunt was deemed to be negligible. No complications occurred. After the second procedure, complete closure was proved by TCD in 16/21 (76.2%) subjects. One patient received a third device. During follow-up (41 ± 19 months), no cerebrovascular ischemic accidents occurred.

CONCLUSION

A second percutaneous PFO occlusion device can be safely implanted in patients with significant rRLS. However, a moderate-to-large rRLS on TCD and/or TEE may not necessarily represent a significant risk of further paradoxical embolization.

Impact of transcatheter closure of patent foramen ovale in the evolution of migraine and role of residual shunt

OBJECTIVES

To retrospectively evaluate the impact on daily activities of transcatheter closure of patent foramen ovale (PFO) versus medical therapy in patients with migraine and to analyze the role of the residual shunt after PFO closure.

BACKGROUND

While non-controlled observational studies reported an improvement of migraine after PFO closure, a randomized trial has shown no benefit of such an intervention. The role of residual shunt after PFO closure is also poorly known.

METHODS

Out of 217 patients with migraine and echocardiographic evidence of PFO, 89 were managed with percutaneous PFO closure (Group A) while 128 were medically treated (Group B). All MIDAS questionnaires were obtained at the first evaluation and repeated at least 6 months after the index evaluation or after the PFO closure. All the patients were also asked to give a subjective estimate of their migraine status. A postprocedural transcranial Doppler study was available in 70 patients in Group A.

RESULTS

The mean basal MIDAS score did not differ between the two groups (p = 0.859). After a mean follow-up (FU) of 1399 ± 982 days the MIDAS score decreased significantly in both groups (Group A baseline vs FU, p < 0.001; Group B baseline vs FU, p < 0.001), but no differences were observed between groups (p = 0.204). However a significantly higher number of Group A patients reported a perceived clinical benefit or the disappearance of migraine compared to Group B (p < 0.001). Patients with moderate or severe residual right to left shunt were no more likely to have an higher MIDAS score or to complain of migraine than those with mild or no shunt.

CONCLUSIONS

Although the overall evolution of migraine is not significantly different, the abolition of migraine occurs in a larger proportion after PFO closure.

[Psychiatric features before and after intervention: a study of patients affected by severe obesity undergoing adjustable gastric banding]

AIM

This study identifies psychological features and the evolution of psychiatric symptoms in a group of patients affected by obesity, who underwent adjustable gastric banding.

MATERIALS AND METHODS

In this group, other than clinical visit, test SCL-90 is made in preoperative time. In postoperative SCL-90, TAS and BES were carried out. Patients evaluated before and after bariatric surgery were 220 and 115, respectively. SCL-90 test made before bariatric surgery showed high values (>0.7) for cluster related to somatization, interpersonal sensitivity, paranoid ideation, depression and obsessive compulsive disorder.

DISCUSSION

Depression symptoms were more important in patients undergoing endogastric balloon placement (mean value of 0.9). Anxious symptoms showed a mean value of 0.73 in patients undergoing endogastric balloon placement as compared to a mean value of 0.52 in patients undergoing gastric banding.

CONCLUSIONS

Our findings show that in patients undergoing bariatric surgery, depressive symptoms are more common preoperatively and normalize at follow-up. This confirms that a possible cause of depression is obesity. The present study also shows that anxious symptoms are lower in obese patients.

Safety of SSRIs during pregnancy: a controlled study

OBJECTIVE

The objective of our study was to analyze the efficacy and the safety of SSRIs during pregnancy.

METHODS

A group of 30 pregnant women affected by Major Depressive Disorder by SCID I interview (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision criteria) and treated with selective serotonin reuptake inhibitor (SSRI) were included in the study. They were matched to a comparison group of 26 pregnant women.

RESULTS

There were no statistically significant differences in any of the pregnancy outcomes of interest between the treated women and comparison group. There was no statistically significant association in newborns of women treated with an SSRI and the control group in the first and fifth minute Apgar score, and no newborns were admitted to neonatal Intensive Care Units.

CONCLUSIONS

No definitive association between use of SSRIs during pregnancy and an increased risk of birth defects or other adverse outcomes could be found.

Substance-induced psychoses: a critical review of the literature

Substances with psychotomimetic properties such as cocaine, amphetamines, hallucinogens and cannabis are widespread, and their use or abuse can provoke psychotic reactions resembling a primary psychotic disease. The recent escalating use of methamphetamine throughout the world and its association with psychotic symptoms in regular users has fuelled concerns. The use of cannabis and cocaine by young people has considerably increased over recent years, and age at first use has dramatically decreased. There is some evidence that cannabis is now on the market in a more potent form than in previous decades. Furthermore, a large number of studies have reported a link between adolescent cannabis use and the development of stable psychosis in early adulthood. The situation is further complicated by the high rates of concomitant substance use by subjects with a psychotic illness which, especially in young users with an early-phase psychotic disorder, can make diagnosis difficult. This paper reviews the literature concerning the properties of psychotogenic substances and the psychotic symptoms they can give rise to, and discusses the association between substance abuse and psychosis with particular emphasis on the differential diagnosis of a primary and substance-induced psychotic disorder. The findings of this review indicate that psychosis due to substance abuse is commonly observed in clinical practice. The propensity to develop psychosis seems to be a function of the severity of use and dependence. From a phenomenological point of view, it is possible to identify some elements that may help clinicians involved in differential diagnoses between primary and substance-induced psychoses. There remains a striking paucity of information on the outcomes, treatments, and best practices of substance-induced psychotic episodes.

Aggression and psychopharmacological treatments in major psychosis and personality disorders during hospitalisation

BACKGROUND

A number of large-scale studies have shown that there is a relationship between many psychiatric disorders and aggression or violence. As no medication is currently approved for the treatment of aggression, pharmacotherapy (often involving drug combinations) is used on a trial-and-error basis with various degrees of response.

METHOD

The study involved 244 in-patients aged 19-83 years (mean 41.9 ± 11.3 SD). The Modified Overt Aggression Scale (MOAS) was used to assess any aggressive or violent behaviors occurring in the week before admission and upon discharge. Psychopathology was assessed using the Brief Psychiatric Rating Scales (BPRS).

RESULTS

All of the patients showed a significant improvement (p<0.001) in mean weighted total MOAS scores at the end of the study, with no significant differences between the various drugs or combination therapies. The patients who received combination treatments including antidepressants showed a worsening in the weighted total MOAS score (18.46% ± 114.31% SD); the patients who did not receive antidepressants had an improvement (13.61% ± 257.36% SD) (p=0.0069).

CONCLUSIONS

Multivariate testing of the variables age, gender, substance/alcohol abuse, the duration of hospitalisation, the administration of mood stabilisers, and the use of typical or atipical antipsychotics showed that the severity of the psychopathological picture correlated significantly with the presence of violence, whereas the effect of combined antidepressant treatment on violent behavior was only relative.
