School-based prevention for illicit drugs use: a systematic review

OBJECTIVE To evaluate the effectiveness of school-based interventions in preventing or reducing drug use. METHODS The search strategy was conducted according to the Cochrane Collaboration method, and applied to MEDLINE, EMBASE, ERIC, PSYCHINFO, Cochrane Library, ACP Journal Club, Cochrane Drugs and Alcohol Group Register. RCTs and CCTs evaluating school-based interventions designed to prevent substance use were reviewed. Data were extracted independently by two reviewers. Quality was assessed. Interventions were classified as skills, affective, and knowledge focused. RESULTS 29 RCTs were included; 28 were conducted in the USA; most were focused on 6th-7th grade students. Compared with usual curricula, skills-based interventions significantly reduce marijuana use (RR=0.82; 95% CI: 0.73, 0.92) and hard drug use (RR=0.45; 95% CI: 0.24, 0.85), and improve decision-making skills, self-esteem, peer pressure resistance (RR=2.05; 95% CI: 1.24, 3.42) and drug knowledge. Compared with usual curricula, affective interventions improve decision-making skills and drug knowledge, and knowledge-focused programs improve drug knowledge. Skills-based interventions are better than affective ones in improved self-efficacy. No differences are evident for skills vs. knowledge-focused programs on drug knowledge. Affective interventions improve decision-making skills and drug knowledge to a higher degree than knowledge-focused programs. CONCLUSION Skills-based programs help to deter drug use. Well designed, long-term randomised trials, and evaluation of intervention components are required.

Decennial trends of social differentials in smoking habits in Italy

AbstractObjective: To present social trends of smoking habits in Italy during the period 1980–1994. Methods: Data from five national health surveys (1980, 1983, 1986–1987, 1990–1991, 1994) were analyzed in order to calculate smoking prevalences. Education attained was used as social class indicator. Main measures: SDPs (prevalence rate standardized on the 1981 Italian population) and PRs (prevalence ratios primary school/degree). Confidence intervals and p-values were calculated as indicators of statistical significance. Results: Among men SDP decreased from 59.5% in 1980 to 37.3% in 1994 and PRs for social classes varied from 1.21 in 1980 to 1.47 in 1994. Corresponding results for women were 17.9% to 20.0% and 0.36 to 0.73. Conclusions: Lower-educated men smoke more than those in higher social categories, and data collected during 1980–1994 in Italy show a tendency to increase such differentials. Among women this pattern was the opposite in 1980, with a tendency to reduce differences over time. Therefore, for both genders data show a progressive disadvantage for the low-educated categories. The greater compliance of better-educated groups with anti-smoking interventions must be taken into account, and should suggest “unequal” interventions that can be more effective among disadvantaged social groups.

Effectiveness of an Informative Video on Reducing Anxiety Levels in Patients Undergoing Elective Coronarography: An RCT

Background: Anxiety levels have a considerable effect on patients during hospitalization. Cardiology Departments are characterized by a high turn-over of patients and it is necessary to give clear and exhaustive information routinely in compliance with legal and deontological requirements. Aims: The aim of the study was to evaluate the effectiveness of an informative video, devised for patients undergoing coronarography, on reducing anxiety levels and getting more satisfaction from the received information. Methods: A two arm RCT design was chosen. The patients in both study arms received standard care while the informative video was shown in the treatment group. The Spielberger scale was used to measure anxiety levels before the procedure while satisfaction as to the received information was measured using a scale with semantic indications. Results: Ninety-three patients accepted to take part in the study. The weighted mean difference (WMD) between the anxiety levels of the treated and controlled groups was − 8.24 (CI 95%: − 12.04/− 4.44; p < 0.00001). The WMD of the level of satisfaction for the received information was + 22.23 (CI 95%: + 12.73 /+ 31.73; p < 0.00001). Conclusions: The use of the informative video in Cardiology Departments proves to be highly recommended as an instrument to lower anxiety levels and increase significantly the level of satisfaction deriving from the received information.

Every-other-day interferon beta-1b versus once-weekly interferon beta-1a for multiple sclerosis (INCOMIN Trial) II: analysis of MRI responses to treatment and correlation with NAb

Background In RRMS, clinical exacerbations are usually associated with different types of active lesions at MRI, including: hyperintense lesions on T1-weighted post-gadolinium sequences; new hyperintense lesions or enlarging old lesions on PD/T2-weighted scans; or new hypointense lesions on T1-weighted pre-Gd sequences. Objective/methods Primary outcome was the occurrence of patients with at least one active MRI lesion of the different types indicated above during treatment with 250 mg every other day (EOD) interferon beta (IFNβ)-1b or 30 mg once weekly (OW) IFNβ-1a in outpatients with RRMS (INCOMIN Trial). Results The number of patients with at least one ‘active’ lesion, evaluated over the two-year follow-up, was significantly (P=0.014) lower in the EOD IFNβ-1b arm (13/76, 17%) then in the OW IFNβ-1a arm (25/73, 34%). NAb frequency over two-year follow-up was 22/65 (33.8%) in the EOD IFNβ-1b arm and 4/62 (6.5%) in the OW IFNβ-1a arm, significantly greater in the EOD IFNβ-1b arm. Conclusions The development of MRI active lesions is strongly reduced by EOD-IFNβ-1b compared with OW-IFNβ-1a, indicating that EOD-IFNβ-1b is more effective than OW-IFNβ-1a in reducing ongoing inflammation and demyelination in MS. Logistic regression showed that NAb status did not affect the risk of MRI activity.

Patterns of drug use among young men in Piedmont (Italy)

Increasing alarm is shown regarding patterns of polydrug use among young people, particularly regarding recreational drugs. Prevalence of recreational drug usage in Europe is not clearly defined, varying for ecstasy, from 0.2% (Finland, 1995) to 9.2% (UK, 1995) and suggesting a tendency to increase in the last years. The aim of this study is to present patterns of polydrug use among a sample of the general population of young males in Piedmont (Northern Italy), focusing particularly on ecstasy consumption. A cross sectional study was carried out between September and November 1998 on a continuous sample of 3274 18-year-old conscripts. A self-administered anonymous questionnaire on socio-demographic characteristics and substances use was submitted during routine tests. Results showed that the overall lifetime prevalence of drug use is 36.6%; prevalence of polydrug use is 30% and the more frequently associated drugs are LSD, cocaine, inhalants and ecstasy. One hundred and forty five (4.6%) subjects reported having taken ecstasy at least once in their life; 20 of the 145 (13.8%) suffered from negative effects and three (2%) presented to a hospital or to a physician. The risk of ever taking ecstasy is inversely related to fathers education, with a trend that is quite similar to that of heroin consumption but that is different from the trend for cannabis. In conclusion the four major results of this study are: (i) a prevalence of drug consumption similar to other European estimates, with a clear tendency to polydrug use; (ii) for ecstasy, a very high association rate with other substances; (iii) the moderately high prevalence of self-reported symptoms, and (iv) a social distribution of use similar to the one observed for heroin. This last consideration suggests that a high level of attention and further research should be addressed to the natural history of ecstasy use.

Pro-inflammatory cytokine and chemokine mRNA blood level in multiple sclerosis is related to treatment response and interferon-beta dose

Of 37 multiple sclerosis patients, 19 suboptimal responders were randomized to 375 (n=12) or 250µg (n=7) interferon (IFN)-β-1b. mRNA levels of 23 cytokines, chemokines, and chemokine receptors were quantified by TaqMan low-density array (TLDA) real-time polymerase chain reaction. Better treatment responses or increased IFN-β doses were associated with elevated IL-10 and TGF-β and decreased CXCL10, IL-18, IFN-γ, and TNF-α transcript levels. Adjusting for dose, poor treatment responses resulted in a 4-fold increase in CXCL10 and IFN-γ expression (Mantel-Haenszel RR=3.74, p<0.0001). CXCL10 and IFN-γ mRNA levels were reliable indicators of treatment response. TLDA can be used to tailor IFN-β-1b therapy.

Outcomes of Pregnancies after Kidney Transplantation: Lessons Learned from CKD. A Comparison of Transplanted, Nontransplanted Chronic Kidney Disease Patients and Low-Risk Pregnancies: A Multicenter Nationwide Analysis

Background Kidney transplantation (KT) may restore fertility in chronic kidney disease (CKD). The reasons why maternofetal outcomes are still inferior to the overall population are only partially known. Comparison with the CKD population may offer some useful insights for management and counselling. Aim of this study was to analyse the outcomes of pregnancy after KT, compared with a large population of nontransplanted CKD patients and with low-risk control pregnancies, observed in Italy the new millennium. Methods We selected 121 live-born singletons after KT (Italian study group of kidney in pregnancy, national coverage about 75%), 610 live-born singletons in CKD, and 1418 low-risk controls recruited in 2 large Italian Units in the same period (2000-2014). The following outcomes were considered: maternal and fetal death; malformations; preterm delivery; small for gestational age (SGA) baby; need for the neonatal intensive care unit; doubling of serum creatinine or increase in CKD stage. Data were analyzed according to kidney diseases, renal function (staging according to CKD-epidemiology collaboration), hypertension, maternal age, parity, ethnicity. Results Maternofetal outcomes are less favourable in CKD and KT as compared with the low-risk population. CKD stage and hypertension are important determinants of results. Kidney transplantation patients with estimated glomerular filtration rate greater than 90 have worse outcomes compared with CKD stage 1 patients; the differences level off when only CKD patients affected by glomerulonephritis or systemic diseases (“progressive CKD”) are compared with KT. In the multivariate analysis, risk for preterm and early-preterm delivery was linked to CKD stage (2-5 vs 1: relative risk 3.42 and 3.78) and hypertension (RR 3.68 and 3.16) while no difference was associated with being a KT or a CKD patient. Conclusions The maternofetal outcomes in patients with kidney transplantation are comparable with those of nontransplanted CKD patients with similar levels of kidney function impairment and progressive and/or immunologic kidney disease.

The OPTimization of Interferon for MS Study: 375 μg interferon beta-1b in suboptimal responders

We aimed to evaluate the safety and MRI efficacy of interferon beta-1b (IFNβ-1b) 375 μg (subcutaneously [sc] every other day [eod]) in relapsing-remitting multiple sclerosis (RRMS) patients with a suboptimal response to IFNβ-1b 250 μg, i.e., with MRI activity or relapses. The OPTimization of Interferon for MS (OPTIMS) study was a prospective multicenter randomized phase 2 trial comprising a 6-month run-in phase (to identify suboptimal responders) and a 6-month randomized phase of open-label clinical and blinded MRI follow-up. During run-in all patients were treated with IFNβ-1b 250 μg sc eod; during the study phase suboptimal treatment responders were randomized either to IFNβ-1b 250 or 375 μg sc eod. Primary outcome was the proportion of patients without MRI activity during study Months 9–12 according to the intention-totreat principle. 216 RRMS patients entered the study: 83 suboptimal responders were identified and randomized, 7 refused to continue treatment, 76 were included in the analysis. More patients treated with 375 μg had no MRI activity at Months 9–12 (30/36 vs.16/40; relative risk, 0.28; 95 % confidence interval, 0.08–0.47; p = 0.0001). Sensitivity analysis (“worst case scenario”) confirmed the results. No new or unexpected adverse events were observed, but there was a trend towards more withdrawals in the 375 μg group. Increasing the dose of IFNβ-1b from 250 μg to 375 μg is a successful strategy for reducing subclinical signs of disease activity in RRMS patients. Further studies are needed to show whether this dose may also improve clinical efficacy.

Methadone treatment in clinical practice in Italy: need for improvement

Background: Methadone at appropriate doses has been demonstrated to be the most effective means for retaining patients in treatment and suppressing heroin use. Aim: To describe the modalities of day-to-day provision of methadone maintenance treatments (MMT) in Italian public health centres and to analyze the duration of MMTs by dose and by association with psychosocial treatments. Patients and Methods: We analyzed 8,378 subjects, 18 years of age or over, enrolled between September 1998 and March 2001 in one of 115 public treatment centres for heroin dependence in Italy. Treatment data were collected for each subject from enrolment to the end of the study period (maximum of 18 months). Results: Of the total of 29,495 treatments delivered, 21.0% were methadone maintenance, and 34.4% were methadone detoxification. Fifty percent of MMTs offered had a mean dose less than or equal to 40 mg/day, and only 19% had doses higher than or equal to 60 mg/day; treatments with doses higher than 60 mg/day lasted longer than treatments with lower doses. Differences in treatment length were observed between MMTs associated with a psychosocial treatment and those offered alone, only for doses <60 mg/day. Conclusions: In Italy, MMTs are delivered at inappropriate doses in more than 80% of the cases. The increase of methadone doses to adequate levels as indicated by the literature is necessary to ensure proper and effective use of MMTs in public treatment centres for heroin users.

Does substance use disorder affect clinical expression in first-hospitalization patients with schizophrenia? Analysis of a prospective cohort

Although several papers reported a wide range of negative outcomes among patients with both schizophrenia and Substance Use Disorder (SUD), only a few studies evaluated the impact of SUD on psychopathology and thus on the length of first-hospitalization. The aim of the present study was to compare clinical expression of first-episode of schizophrenia between inpatients with and without SUD, giving close attention to the length of stay. One hundred and thirty inpatients at first-episode of schizophrenia were assigned to either SUD or not SUD group depending on SUD diagnosis and were assessed through BPRS at admission, during hospitalization and at discharge. Cross-sectional and longitudinal statistical analysis were performed to investigate differences between groups and also a linear regression was used to evaluate relationship between length of stay and BPRS scores. SUD group showed more disorganization at admission, less marked improvement of symptoms (disorganization, thought disturbance, anergia), and longer hospital stay than not SUD group. Moreover BPRS total score during hospitalization was a significant positive predictor for length of stay. Taken together, these findings suggest that SUD patients have a more severe and drug-resistant expression of schizophrenia, hence, they need longer treatment to achieve the overall symptoms improvement required for discharge.
