Was Bernanke Right? Targeting Asset Prices may not be a Good Idea after all

Should the central bank prevent “excessive” asset price dynamics or should it wait until the boom spontaneously turns into a crash and intervene only afterwards? The debate over this issue goes back at least to the exchange between Bernanke-Gertler (BG) and Cecchetti but has not settled yet. In their 1999 paper BG claimed that price stability and financial stability are ‘highly complementary and mutually consistent objectives’ in a flexible inflation targeting regime which ‘dictates that central banks ... should not respond to changes in asset prices, except insofar as they signal changes in expected inflation.’ (BG, 1999, p.18). This conclusion is straightforward within the variant of the NK-DSGE framework used by BG in which asset inflation shows up as a factor ‘augmenting’ the IS curve. In the present paper, we pursue a different modelling strategy so that, in the end, asset price dynamics will be incorporated into the NK Phillips curve. In our context it is not true anymore that by focusing on inflation the central bank is also checking an asset price boom. We put ourselves, therefore, in the best position to obtain a significant stabilizing role for asset price targeting. It turns out, however, that inflation volatility is higher in the asset price targeting case. After all, therefore, targeting asset prices may not be a good idea.cost channel, asset prices, Taylor rules

Costi del trattamento con oloprazina nelle fasi iniziali della schizofrenia

Objective: In Italy, use of olanzapine in the public sector was limited by law to patients that had failed treatment with conventional antipsychotics, due to the higher purchase price of the drug. This restriction prevented first-episode patients and patients early in the course of their illness from being treated with olanzapine. The present study investigates economic consequences of this policy. Design: The present study retrospectively outlines treatment costs of patients switched to olanzapine during the early stages of schizophrenia as compared to the costs of patients switched during a later stage of the illness. Setting: The study was conducted within Italian Community Mental Health Services. Patients: The cost of pharmacological and non-pharmacological treatment was retrospectively calculated in 25 out-patients with schizophrenia and related disorders over a one-year span. Thirteen patients were switched to olanzapine in the early stage of their illness, prior to drug approval under a compassionate use regimen. Twelve patients started olanzapine under the restriction in a later stage of illness following failed treatment with a conventional antipsychotic. Results: While total treatment costs between the two groups was similar, cost distribution was different. Early Switch patients had higher drug costs and higher rehabilitation costs, while Late Switch patients had higher hospitalisation costs. Conclusions: Small patient numbers and design limitations prevent conclusions being drawn regarding the ultimate impact on outcome and total treatment cost of restriction of olanzapine to second-line use. Despite this, our findings demonstrate that within the context of the Italian CMHS, patients treated with olanzapine while still in the early stages of schizophrenia do not necessarily cost more overall compared to patients who receive olanzapine after failing treatment with a conventional antipsychotic

Integration between Primary Care and Mental Health Services in Italy: Determinants of Referral and Stepped Care

This study, carried out in the context of a collaborative care program for common mental disorders, is aimed at identifying the predictors of Primary Care Physician (PCP) referral to Community Mental Health Center (CMHC) and patterns of care. Patients with depression or anxiety disorders who had a first contact with CMHCs between January 1, 2007–December 31, 2009 were extracted from Bologna Local Health Authority database. A classification and regression tree procedure was used to determine which combination of demographic and diagnostic variables best distinguished patients referred by PCPs and to identify predictors of patterns of care (consultation, shared care, and treatment at the CMHC) for patients referred by PCPs. Of the 8570 patients, 57.4% were referred by PCPs. Those less likely to be referred by PCPs were living in the urban area, suffered from depressive disorder, and were young. As to the pattern of care, patients living in the urban area were more likely to receive shared care compared with those living in the nonurban area, while the reverse was true for consultation. Predictors of CMHC treatment were depression and young age. Prospective studies are needed to assess length, quantity, and quality of collaborative treatment for common mental disorder delivered at any step of care

Clinical management of endoscopically resected pT1 colorectal cancer

Background Implementation of colorectal cancer (CRC) screening programs increases endoscopic resection of polyps with early invasive CRC (pT1). Risk of lymph node metastasis often leads to additional surgery, but despite guidelines, correct management remains unclear. Our aim that are diagnosed and treated endoscopically and this number is expected to increase [1,2].Methods We retrospectively reviewed patients undergoing endoscopic resection of pT1 CRC from 2006 to 2016. Clinical, endoscopic, surgical treatment, and follow-up data were collected and analyzed. Lesions were categorized according to endoscopic/histological risk-factors into low and high risk groups. Comorbidities were classified according to the Charlson comorbidity index (CCI). Surgical referral for each group was computed, and dissociation from current European CRC screening guidelines recorded. Multivariate analysis for factors affecting the post-endoscopic surgery referral was performed.Results Seventy-two patients with endoscopically resected pT1-CRC were included. Overall, 20 (27.7%) and 52 (72.3%) were classified as low and high risk, respectively. In the low risk group, 11 (55%) were referred to surgery, representing over-treatment compared with current guidelines. In the high risk group, nonsurgical endoscopic surveillance was performed in 20 (38.5%) cases, representing potential under-treatment. After a median follow-up of 30 (6-130) months, no patients developed tumor recurrence. At multivariate analysis, age (OR 1.21, 95 %CI 1.02 -1.42; P = 0.02) and CCI (OR 1.67, 95 %CI 1.12 -3.14; P= 0.04) were independent predictors for subsequent surgery.Conclusions A substantial rate of inappropriate post-endoscopic treatment of pT1-CRC was observed when compared with current guidelines. This was apparently related to an overestimation of patient-related factors rather than endoscopically or histologically related factors

Suicidality in patients with obsessive-compulsive and related disorders (OCRDs): A meta-analysis

© 2021 The Authors. Published by Elsevier Inc. This is an open access article under the CC BY-NC-ND license (http://creativecommons.org/licenses/by-nc-nd/4.0/Introduction Previous meta-analyses showed that OCD is associated with a substantial risk of suicidal behaviours. Conclusive rates of suicidal ideation (current and lifetime) and suicide attempts based on pooled prevalence rates have not so far been calculated using meta-analysis for the other DSM-5 Obsessive-Compulsive Related Disorders (OCRDs). Objectives This meta-analysis aims to separately calculate the pooled prevalence rates of lifetime suicide attempts and current or lifetime suicidal ideation in BDD, Hoarding Disorder (HD), Skin Picking Disorder (SPD) and Trichotillomania (TTM) and to identify factors associated with increased suicide rates. Methods Our protocol was pre-registered with PROSPERO (CRD42020164395). A systematic review and meta-analysis following PRISMA reporting guidelines was performed by searching in PubMed/Medline, PsycINFO, Web of Science and CINAHL databases from the date of the first available article to April 20th, 2020. Stata version 15 was used for the statistical analysis. Given the small number of studies in TTM and SPD, the two grooming disorders were grouped together. Meta-analyses of proportions based on random effects (Der-Simonian and Laird method) were used to derive the pooled estimates. Results Thirty-nine studies (N=4559 participants) were included: 23 for BDD, 8 for HD, 7 for Grooming Disorders. For BDD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was, respectively 35.2% (CI:23.4-47.8), 37.2% (CI:23.8-51.6) and 66.1% (CI:53.5-77.7). For HD, the pooled prevalence of lifetime suicide attempts, current and lifetime suicidal ideation was 24.1% (CI:12.8-37.6), 18.4% (CI:10.2-28.3) and 38.3% (CI:35.0-41.6), respectively. For Grooming Disorders, the pooled prevalence of lifetime suicide attempts and current suicidal ideation were 13.3% (CI:5.9-22.8) and 40.4% (CI:35.7-45.3), respectively (no data available for lifetime suicidal ideation). Conclusions The OCRDs as a group are associated with relatively high rates of suicidal behaviour. Through indirect comparisons, we infer that BDD has the greatest risk. Comorbid substance abuse, possibly reflecting poor underlying impulse control, is associated with higher rates of suicidal behaviour in BDD. Our data emphasize the need for clinicians to consider the risk of suicidal behaviour in the management of patients presenting with all forms of OCRDs.Peer reviewe

Metabolic risk factor profile associated with use of second generation antipsychotics: a cross-sectional study in a community mental health centre

open9noBACKGROUND: Second generation antipsychotics (SGA) have demonstrated several advantages over first generation antipsychotics (FGA) in terms of positive, negative, cognitive, and affective symptoms and a lower propensity for extrapyramidal side effects. Despite these undeniable advantages, SGA have been associated with causing and exacerbating metabolic disorders, such as obesity, diabetes, and hyperlipidemia. This cross sectional study aimed to evaluate the metabolic risk factor profile associated with use of SGAs in comparison with non -treated control patients. METHODS: The study was carried out at a Community Mental Health Centre (CMHC) in Bologna. The study subjects were outpatients with serious mental disorders treated with SGA (clozapine, olanzapine, risperidone, quetiapine). A sample of adult men and women suffering from idiopathic hyperhydrosis, without psychiatric history or antipsychotic treatment, were randomly selected from outpatients of the Department of Neurology in Bologna as a reference group. We investigated differences among the treatment and reference groups for glycaemia, cholesterolaemia and triglyceridaemia levels. RESULTS: The study sample was composed of 76 patients, 38 males and 38 females. The reference group was composed of 36 subjects, 19 females and 17 males. All patients treated with SGAs had higher mean glycaemia and triglyceridaemia and a significantly higher risk of receiving a diagnosis of hyperglycaemia and hypertriglyceridaemia than the reference group. We did not find any differences in mean glycaemia or mean triglyceridaemia levels among treatment groups. Patients with clozapine had a significantly higher mean BMI value and rate of obesity than patients treated with other SGAs. CONCLUSION: The rate of obesity and metabolic disorders observed in this study were higher than the prevalence in the control group and similar to that previously reported in psychiatric samples; these findings imply per se that more attention should be paid to the metabolic condition of psychiatric patients. In line with the International Consensus Conferences we recommend that monitoring of weight, fasting plasma glucose, cholesterol and triglyceride levels be obtained in routine clinical practice with all antipsychoticsopenTarricone I.; Casoria M.; Ferrari Gozzi B.; Grieco D.; Menchetti M.; Serretti A.; Ujkaj M.; Pastorelli F.; Berardi D.Tarricone I.; Casoria M.; Ferrari Gozzi B.; Grieco D.; Menchetti M.; Serretti A.; Ujkaj M.; Pastorelli F.; Berardi D

Pure laparoscopic formal right hepatectomy versus anatomical posterosuperior segmental resections : a comparative study

Background: To analyze the differences in perioperative outcomes between laparoscopic formal right hepatectomies (RH) and laparoscopic anatomical posterosuperior (PS) resections, including segmentectomies in PS segment SVII and right posterior sectionectomies (segment VI and VII resection). Methods: A retrospective analysis of all patients undergoing laparoscopic formal RHs and anatomical PS resections, including segmentectomies in PS segment SVII and right posterior sectionectomies (segment VI and VII resection), between January 2010 and August 2017 was performed. The two groups were compared in terms of patients’ characteristics, intraoperative parameters, and short-term outcomes. Results: Sixty-eight patients were included of which 32 RHs and 36 anatomical PS resections. In the PS resection group, 18 had a segmentectomy of segment VII and 18 had a bisegmentectomy of both segments VI and VII. Patients’ preoperative data were comparable. The lesion size was higher in the RHs (P<0.001). A significant shorter operative time was found in the PS group: 280 [230–315] vs. 357 [300–463] min in the RH group (P<0.001). Blood loss was comparable: 520 [390–906] in the RHs vs. 560 [370–1,030] in the PS group (P=0.595). The overall morbidity rate was comparable being 25% in the RHs and 22.2% in the PS group (P=1.000). A longer length of stay (LOS) {7 [5–8] vs. 5 [4–7] days, P=0.012} and higher readmission rate (12.5% vs. 0%, P=0.044) was observed in the RHs compared to the PS cohort. Concerning surgical margins, the R0 rate was comparable in the two groups; 90.9% in the RHs vs. 95.2% in the PS group (P=1.000). Conclusions: When deemed feasible based on lesion position and size, the laparoscopic parenchyma-preserving approach using anatomical PS segmental resections is associated with shorter hospital stay and a lower readmission rate in respect to formal RH. Overall, short-term surgical parameters indicated that both procedures are safe and feasible in experienced hands, however both demand a great deal of technical expertise

Neuroactive Steroids in First-Episode Psychosis: A Role for Progesterone?

Neuroactive steroids may play a role in the pathophysiology of psychotic disorders, but few studies examined this issue. We compared serumlevels of cortisol, testosterone, dehydroepiandrosterone, and progesterone between a representative sample of firstepisode psychosis (FEP) patients and age- and gender-matched healthy subjects. Furthermore, we analyzed the associations between neuroactive steroids levels and the severity of psychotic symptom dimensions.Male patients had lower levels of progesterone than controls
