Italian guidelines for the management of adult individuals with overweight and obesity and metabolic comorbidities that are resistant to behavioral treatment.

AIM: This guideline (GL) is aimed at providing a clinical practice reference for the management of adult patients with overweight or obesity associated with metabolic complications who are resistant to lifestyle modification. METHODS: Surgeons, endocrinologists, gastroenterologists, psychologists, pharmacologists, a general practitioner, a nutritionist, a nurse and a patients' representative acted as multi-disciplinary panel. This GL has been developed following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. A systematic review and network meta-analysis was performed by a methodologic group. For each question, the panel identified potentially relevant outcomes, which were then rated for their impact on therapeutic choices. Only outcomes classified as "critical" and "important" were considered in the systematic review of evidence. Those classified as "critical" were considered for clinical practice recommendations. Consensus on the direction (for or against) and strength (strong or conditional) of recommendations was reached through a majority vote. RESULTS: The present GL provides recommendations about the role of both pharmacological and surgical treatment for the clinical management of the adult patient population with BMI > 27 kg/m2 and < 40 kg/m2 associated with weight-related metabolic comorbidities, resistant to lifestyle changes. The panel: suggests the timely implementation of therapeutic interventions in addition to diet and physical activity; recommends the use of semaglutide 2.4 mg/week and suggests liraglutide 3 mg/day in patients with obesity or overweight also affected by diabetes or pre-diabetes; recommends semaglutide 2.4 mg/week in patients with obesity or overweight also affected by non-alcoholic fatty liver disease; recommends semaglutide 2.4 mg/week as first-line drug in patients with obesity or overweight that require a larger weight loss to reduce comorbidities; suggests the use of orlistat in patients with obesity or overweight also affected by hypertriglyceridemia that assume high-calorie and high-fat diet; suggests the use of naltrexone/bupropion combination in patients with obesity or overweight, with emotional eating; recommends surgical intervention (sleeve gastrectomy, Roux-en-Y gastric bypass, or metabolic gastric bypass/gastric bypass with single anastomosis/gastric mini bypass in patients with BMI ≥ 35 kg/m2 who are suitable for metabolic surgery; and suggests gastric banding as a possible, though less effective, surgical alternative. CONCLUSION: The present GL is directed to all physicians addressing people with obesity-working in hospitals, territorial services or private practice-and to general practitioners and patients. The recommendations should also consider the patient's preferences and the available resources and expertise.

European guidelines for quality assurance in colorectal cancer screening and diagnosis: overview and introduction to the full supplement publication.

Population-based screening for early detection and treatment of colorectal cancer (CRC) and precursor lesions, using evidence-based methods, can be effective in populations with a significant burden of the disease provided the services are of high quality. Multidisciplinary, evidence-based guidelines for quality assurance in CRC screening and diagnosis have been developed by experts in a project co-financed by the European Union. The 450-page guidelines were published in book format by the European Commission in 2010.  They include 10 chapters and over 250 recommendations, individually graded according to the strength of the recommendation and the supporting evidence. Adoption of the recommendations can improve and maintain the quality and effectiveness of an entire screening process, including identification and invitation of the target population, diagnosis and management of the disease and appropriate surveillance in people with detected lesions. To make the principles, recommendations and standards in the guidelines known to a wider professional and scientific community and to facilitate their use in the scientific literature, the original content is presented in journal format in an open-access Supplement of Endoscopy. The editors have prepared the present overview to inform readers of the comprehensive scope and content of the guidelines.

Regional long-term analysis of dietary isotopes in Neolithic southeastern Italy: new patterns and research directions.

Isotopic analyses of prehistoric diet have only recently reached the threshold of going beyond site-focused reports to provide regional syntheses showing larger trends. In this work we present the first regional analysis for Neolithic southeastern Italy as a whole, including both substantial original data and a review of the available published data. The results show that dietary isotopes can shed new light on a number of traditional and important questions about Neolithic foodways. First, we observe regional variations in the distribution of stable isotope values across the area, suggesting variability in the Neolithic diet. Secondly, we show that, although the plant food calorific intake was primary for these communities, animal products were also important, representing on average 40% of the total calories. Third, we note that marine fish was only minorly consumed, but that this could be an underestimation, and we observe some variability in the regions considered, suggesting differences in local human-environment interactions. People in different regions of southeastern Italy may have consumed different versions of a common Neolithic diet. Regional synthesis also allows us to take stock of gaps and new directions in the field, suggesting an agenda for Neolithic isotopic research for the 2020s.

European guidelines for quality assurance in colorectal cancer screening and diagnosis. First Edition--Principles of evidence assessment and methods for reaching recommendations.

Multidisciplinary, evidence-based guidelines for quality assurance in colorectal cancer screening and diagnosis have been developed by experts in a project coordinated by the International Agency for Research on Cancer. The full guideline document covers the entire process of population-based screening. It consists of 10 chapters and over 250 recommendations, graded according to the strength of the recommendation and the supporting evidence. The 450-page guidelines and the extensive evidence base have been published by the European Commission. The principles of evidence assessment and methods for reaching recommendations are presented here to promote international discussion and collaboration by making the principles and methods used in developing the guidelines known to a wider professional and scientific community. Following this methodology in the future updating of the guidelines has the potential to enhance the control of colorectal cancer through improvement in the quality and effectiveness of the screening process, including multidisciplinary diagnosis and management of the disease.

Maintenance agonist treatments for opiate dependent pregnant women.

BACKGROUND: The prevalence of opiate use among pregnant women ranges from 1% to 2% to as much as 21%. Heroin crosses the placenta and pregnant opiate dependent women experience a six fold increase in maternal obstetric complications such as low birth weight, toxaemia, 3rd trimester bleeding, malpresentation, puerperal morbidity, fetal distress and meconium aspiration. Neonatal complications include narcotic withdrawal, postnatal growth deficiency, microcephaly, neurobehavioral problems, increased neonatal mortality and a 74-fold increase in sudden infant death syndrome. OBJECTIVES: To assess the effectiveness of any maintenance treatment alone or in combination with psychosocial intervention compared to no intervention, other pharmacological intervention or psychosocial interventions on child health status, neonatal mortality, retaining pregnant women in treatment, and reducing use of substances SEARCH STRATEGY: We searched Cochrane Drugs and Alcohol Group' Register of Trials (June 2007), PubMed (1966 - June 2007), CINAHL (1982- June 2007), reference lists of relevant papers, sources of ongoing trials, conference proceedings, National focal points for drug research. Authors of included studies and experts in the field were contacted. SELECTION CRITERIA: Randomised controlled trials enrolling opiate dependent pregnant women DATA COLLECTION AND ANALYSIS: The authors assessed independently the studies for inclusion and methodological quality. Doubts were solved by discussion. MAIN RESULTS: We found three trials with 96 pregnant women. Two compared methadone with buprenorphine and one methadone with oral slow morphine. For the women there was no difference in drop out rate RR 1.00 (95% CI 0.41 to 2.44) and use of primary substance RR 2.50 (95% CI 0.11 to 54.87) between methadone and buprenorphine, whereas oral slow morphine seemed superior to methadone in abstaining women from the use of heroin RR 2.40 (95% CI 1.00 to 5.77)For the newborns in one trial buprenorphine performed better than methadone for birth weight WMD -530 gr (95% CI -662 to -397), this result is not confirmed in the other trial. For the APGAR score both studies didn't find significant difference . No differences for NAS measures used. Comparing methadone with oral slow morphine no differences for birth weight and mean duration of NAS. The APGAR score wasn't considered. AUTHORS' CONCLUSIONS: We didn't find any significant difference between the drugs compared both for mother and for child outcomes; the trials retrieved were too few and the sample size too small to make firm conclusion about the superiority of one treatment over another. There is an urgent need of big randomized controlled trials.

Anticonvulsants for cocaine dependence.

BACKGROUND: Cocaine dependence is a major public health problem that is characterized by recidivism and a host of medical and psychosocial complications. Although effective pharmacotherapy is available for alcohol and heroin dependence none exists currently for cocaine dependence despite two decades of clinical trials primarily involving antidepressant, anti convulsivant and dopaminergic medications. There has been extensive consideration of optimal pharmacological approaches to the treatment of cocaine dependence with consideration of both dopamine antagonists and agonists. Anticonvulsants have been candidates for the treatment of addiction based on the hypothesis that seizure kindling-like mechanisms contribute to addiction. OBJECTIVES: To evaluate the efficacy and the acceptability of anticonvulsants for cocaine dependence SEARCH STRATEGY: We searched the Cochrane Drugs and Alcohol Groups specialised register (issue 4, 2007), MEDLINE (1966 - march 2007), EMBASE (1988 - march 2007), CINAHL (1982- to march 2007) SELECTION CRITERIA: All randomised controlled trials and controlled clinical trials which focus on the use of anticonvulsants medication for cocaine dependence DATA COLLECTION AND ANALYSIS: Two authors independently evaluated the papers, extracted data, rated methodological quality MAIN RESULTS: Fifteen studies (1066 participants) met the inclusion criteria for this review: the anticonvulsants drugs studied were carbamazepine, gabapentin, lamotrigine, phenytoin, tiagabine, topiramate, valproate. No significant differences were found for any of the efficacy measures comparing any anticonvulsants with placebo. Placebo was found to be superior to gabapentin in diminishing the number of dropouts, two studies, 81 participants, Relative Risk (RR) 3.56 (95% CI 1.07 to 11.82) and superior to phenythoin for side effects, two studies, 56 participants RR 2.12 (95% CI 1.08 to 4.17). All the other single comparisons are not statistically significant. AUTHORS' CONCLUSIONS: Although caution is needed when assessing results from a limited number of small clinical trials at present there is no current evidence supporting the clinical use of anticonvulsants medications in the treatment of cocaine dependence. Aiming to answer the urgent demand of clinicians, patients, families, and the community as a whole for an adequate treatment for cocaine dependence, we need to improve the primary research in the field of addictions in order to make the best possible use out of a single study and to investigate the efficacy of other pharmacological agent.

Exercises reduce the progression rate of adolescent idiopathic scoliosis: results of a comprehensive systematic review of the literature.

BACKGROUND: A previously published systematic review (Ped.Rehab.2003 - DARE 2004) documented the existence of the evidence of level 2a (Oxford EBM Centre) on the efficacy of specific exercises to reduce the progression of AIS (Adolescent Idiopathic Scoliosis). AIM: To confirm whether the indication for treatment with specific exercises for AIS has changed in recent years. STUDY DESIGN: Systematic review. METHODS: A bibliographic search with strict inclusion criteria (patients treated exclusively with exercises, outcome Cobb degrees, all study designs) was performed on the main electronic databases and through extensive manual searching. We retrieved 19 studies, including one RCT and eight controlled studies; 12 studies were prospective. A methodological and clinical evaluation was performed. RESULTS: The 19 papers considered included 1654 treated patients and 688 controls. The highest-quality study (RCT) compared two groups of 40 patients, showing an improvement of curvature in all treated patients after six months. We found three papers on Scoliosis Intensive Rehabilitation (Schroth), five on extrinsic autocorrection-based methods (Schroth, side-shift), four on intrinsic autocorrection-based approaches (Lyon and SEAS) and five with no autocorrection (three asymmetric, two symmetric exercises). Apart from one (no autocorrection, symmetric exercises, very low methodological quality), all studies confirmed the efficacy of exercises in reducing the progression rate (mainly in early puberty) and/or improving the Cobb angles (around the end of growth). Exercises were also shown to be effective in reducing brace prescription. CONCLUSION: In five years, eight more papers have been published to the indexed literature coming from throughout the world (Asia, the US, Eastern Europe) and proving that interest in exercises is not exclusive to Western Europe. This systematic review confirms and strengthens the previous ones. The actual evidence on exercises for AIS is of level 1b.

Antipsychotic medications for cocaine dependence.

BACKGROUND: Cocaine dependence is a public health problem characterized by recidivism and a host of medical and psychosocial complications. Cocaine dependence remains a disorder for which no pharmacological treatment of proven efficacy exists, although considerable advances in the neurobiology of this addiction could guide future medication development OBJECTIVES: To evaluate the efficacy and the acceptability of antipsychotic medications for cocaine dependence SEARCH STRATEGY: We searched the following sources: MEDLINE (1966 to October 2006), EMBASE (1980 to October 2006), CINAHL (1982 to October 2006), Cochrane Drug and Alcohol Group Specialised Register (October 2006). We also searched the reference lists of trials, the main electronic sources of ongoing trials (National Research Register, meta-Register of Controlled Trials; Clinical Trials.gov) and conference proceedings likely to contain trials relevant to the review. All searches included also non-English language literature. SELECTION CRITERIA: All randomised controlled trials and controlled clinical trials with focus on the use of any antipsychotic medication for cocaine dependence DATA COLLECTION AND ANALYSIS: Two authors independently evaluated the papers, extracted data, rated methodological quality MAIN RESULTS: Seven small studies were included (293 participants): the antipsychotic drugs studied were risperidone, olanzapine and haloperidol. No significant differences were found for any of the efficacy measures comparing any antipsychotic with placebo. Risperidone was found to be superior to placebo in diminishing the number of dropouts, four studies, 178 participants, Relative Risk (RR) 0.77 (95% CI 0.77 to 0.98). Most of the included studies did not report useful results on important outcomes such as side effects, use of cocaine during treatment and craving. The results on olanzapine and haloperidol come from studies too small to give conclusive results. AUTHORS' CONCLUSIONS: Although caution is needed when assessing results from a limited number of small clinical trials there is no current evidence, at the present , supporting the clinical use of antipsychotic medications in the treatment of cocaine dependence. Furthermore, most of the included studies did not report useful results on important outcomes such as side effects, use of cocaine during the treatment and craving. Aiming to answer the urgent demand of clinicians, patients, families, and the community as a whole for an adequate treatment for cocaine dependence, larger randomised investigations should be designed investigating relevant outcomes and reporting data to allow comparison of results between studies. Moreover some efforts should be done also to investigate the efficacy of other type medications, like anticonvulsant, currently used in clinical practice.

A systematic review of physical and rehabilitation medicine topics as developed by the Cochrane Collaboration.

The aim of this paper is to give an overview of the Cochrane Collaboration, its development over the years, and its usefulness for physical and rehabilitation medicine specialists. After introducing the Cochrane Collaboration, we systematically analyzed all titles of the reviews in each of the 50 review groups. For ''Rehabilitation,'' we included not only exercise and physical therapy, but also all of the educational and pharmacological interventions aimed at supporting rehabilitation. The search was performed using Issue 2, 2007 of the Cochrane Library. We retrieved 138 completed reviews that dealt with rehabilitation interventions performed by 20 review groups. No umbrella reviews could be found at present. The most prolific groups in the rehabilitation field were: musculoskeletal (28 reviews), stroke (20), back (18), and the movement disorder group (13). The most discussed intervention was exercise (37 reviews), dealing with physical medicine (20) and pharmacological intervention (11). Six other reviews dealt with multidisciplinary rehabilitation. Low back pain treatment and stroke were the most investigated topics. The Cochrane Collaboration serves today as a main step in increasing an evidence-based approach to medicine and rehabilitation. Europa Medicophysica is continuously increasing its importance and presence in the world of physical and rehabilitation medicine, and part of its mission is to increase and strengthen an evidence-based approach to this field. We will continue to look at the contents of the Cochrane database and regularly report on its updates concerning topics of interest for physical and rehabilitation medicine.

Oral naltrexone maintenance treatment for opioid dependence.

BACKGROUND: Research on the clinical application of oral naltrexone agrees on several things. From a pharmacological perspective, naltrexone works. From an applied perspective, however, this medication is not used since the medication compliance and the retention rates are very poor. OBJECTIVES: To evaluate the effects of naltrexone maintenance treatment versus placebo or other treatments in preventing relapse in opioid addicts after detoxification. SEARCH STRATEGY: We searched the Cochrane Drugs and Alcohol Group Register of Trials (January 2005), Cochrane Central Register of Controlled Trials (CENTRAL - The Cochrane Library Issue 1, 2005), MEDLINE (1973-first year of naltrexone use in humans- January 2005), EMBASE (1974- January 2005), PsycINFO (OVID-January 1985 to January 2004). We inspected reference lists of relevant articles and we contacted pharmaceutical producers of naltrexone, authors and other Cochrane review groups. SELECTION CRITERIA: All randomised and controlled clinical trials which focus on the use of naltrexone maintenance treatment versus placebo, or other treatments to reach sustained abstinence from opiate drugs DATA COLLECTION AND ANALYSIS: Three reviewers independently assessed studies for inclusion and extracted data. One reviewer carried out the qualitative assessments of the methodology of eligible studies using validated checklists. MAIN RESULTS: Ten studies, 696 participants, met the criteria for inclusion in this review. Only two studies described an adequate allocation concealment. The results show that naltrexone maintenance therapy alone or associated with psychosocial therapy is more efficacious that placebo alone or associated with psychosocial therapy in limiting the use of heroin during the treatment (RR 0,72 95% confidence interval 0.58 to 0.90). If we consider only the studies comparing naltrexone with placebo, the difference do not reach the statistical significancy, RR 0.79 (95%CI 0.59 to 1.06). With respect to the number of participants re incarcerated during the study period, the naltrexone associated with psychosocial therapy is more effective than the psychosocial treatment alone; RR 0.50 (95%CI 0.27 to 0.91). No statistically significant benefit was shown in terms of retention in treatment, side effects or relapse results at follow-up for any of the considered comparisons. AUTHORS' CONCLUSIONS: Unfortunately the studies did not provide an objective evaluation of naltrexone treatment in the field of opioid dependence. The conclusions are also limited due to the heterogeneity of the trials both in the interventions and in the assessment of outcomes.

Methadone at tapered doses for the management of opioid withdrawal.

BACKGROUND: Despite widespread use in many countries the evidence of tapered methadone's efficacy in managing opioid withdrawal has not been systematically evaluated. OBJECTIVES: To evaluate the effectiveness of tapered methadone compared with other detoxification treatments and placebo in managing opioid withdrawal on completion of detoxification and relapse rate. SEARCH STRATEGY: We searched: Cochrane Central Register of Controlled Trials (The Cochrane Library Issue 1, 2005), MEDLINE (January 1966 to December 2004), EMBASE (January 1988 to December 2004), PsycINFO (January 1985 to December 2004), and reference lists of articles. We also contacted manufacturers and researchers in the field. SELECTION CRITERIA: All randomised controlled trials which focus on the use of tapered methadone versus all other pharmacological detoxification treatments or placebo for the treatment of opiate withdrawal. DATA COLLECTION AND ANALYSIS: Two reviewers assessed the included studies. Any doubt about how to rate the studies were resolved by discussion with a third reviewer. Study quality was assessed according to the criteria indicated in Cochrane Reviews Handbook 4.2. (Alderson 2004) MAIN RESULTS: Sixteen trials involving 1187 people were included. Comparing methadone versus any other pharmacological treatment we observed no clinical difference between the two treatments in terms of completion of treatment, relative risk (RR) 1.12; 95% CI 0.94 to 1.34 and results at follow-up RR 1.17; 95% CI 0.72 to 1.92. It was impossible to pool data for the other outcomes but the results of the studies did not show significant differences between the considered treatments. These results were confirmed also when we considered the single comparisons: methadone with: adrenergic agonists (11 studies), other opioid agonists (four studies), chlordiazepoxide (study). Comparing methadone with placebo (one study) more severe withdrawal and more drop outs were found in the placebo group. The results indicate that the medications used in the included studies are similar in terms of overall effectiveness, although symptoms experienced by participants differed according to the medication used and the program adopted. AUTHORS' CONCLUSIONS: Data from literature are hardly comparable; programs vary widely with regard to duration, design and treatment objectives, impairing the application of meta-analysis. The studies included in this review confirm that slow tapering with temporary substitution of long acting opioids, accompanied by medical supervision and ancillary medications can reduce withdrawal severity. Nevertheless the majority of patients relapsed to heroin use.

Mass media interventions: effects on health services utilisation.

BACKGROUND: The mass media frequently cover health related topics, are the leading source of information about important health issues, and are targeted by those who aim to influence the behaviour of health professionals and patients. OBJECTIVES: To assess the effects of mass media on the utilisation of health services. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care Group specialised register (1996 to 1999), MEDLINE, EMBASE, Eric, PsycLit (to 1999), and reference lists of articles. We hand searched the journals Communication Research (February 1987 to August 1996), European Journal of Communication (1986 to 1994), Journal of Communication (winter 1986 to summer 1996), Communication Theory (February 1991 to August 1996), Critical Studies in Mass Communication (March 1984 to March 1995) and Journalism Quarterly (1986 to summer 1996). SELECTION CRITERIA: Randomised trials, controlled clinical trials, controlled before-and-after studies and interrupted time series analyses of mass media interventions. The participants were health care professionals, patients and the general public. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed study quality. MAIN RESULTS: Twenty studies were included. All used interrupted time series designs. Fifteen evaluated the impact of formal mass media campaigns, and five of media coverage of health-related issues. The overall methodological quality was variable. Six studies did not perform any statistical analysis, and nine used inappropriate statistical tests (ie not taking into account the effect of time trend). All of the studies apart from one concluded that mass media was effective. These positive findings were confirmed by our re-analysis in seven studies. The direction of effect was consistent across studies towards the expected change. REVIEWER'S CONCLUSIONS: Despite the limited information about key aspects of mass media interventions and the poor quality of the available primary research there is evidence that these channels of communication may have an important role in influencing the use of health care interventions. Although the findings of this review may be affected by publication bias, those engaged in promoting better uptake of research information in clinical practice should consider mass media as one of the tools that may encourage the use of effective services and discourage those of unproven effectiveness.

Mass media interventions: effects on health services utilisation.

BACKGROUND: The mass media frequently cover health related topics, are the leading source of information about important health issues, and are targeted by those who aim to influence the behaviour of health professionals and patients. OBJECTIVES: To assess the effects of mass media on the utilisation of health services. SEARCH STRATEGY: We searched the Cochrane Effective Practice and Organisation of Care Group specialised register, MEDLINE, EMBASE, Eric, PsycLit, and reference lists of articles. We hand searched the journals Communication Research (February 1987 to August 1996), European Journal of Communication (1986 to 1994), Journal of Communication (winter 1986 to summer 1996), Communication Theory (February 1991 to August 1996), Critical Studies in Mass Communication (March 1984 to March 1995) and Journalism Quarterly (1986 to summer 1996). SELECTION CRITERIA: Randomised trials, controlled clinical trials, controlled before-and-after studies and interrupted time series analyses of mass media interventions. The participants were health care professionals, patients and the general public. DATA COLLECTION AND ANALYSIS: Two reviewers independently extracted data and assessed study quality. MAIN RESULTS: Seventeen studies were included. All used interrupted time series designs. Fourteen evaluated the impact of formal mass media campaigns, and three of media coverage of health related issues. The overall methodological quality was variable. Six studies did not perform any statistical analysis, and seven used inappropriate statistical tests (ie not taking into account the effect of time trend). All of the studies apart from one concluded that mass media was effective. These positive findings were confirmed by our re-analysis in seven studies. The direction of effect was consistent across studies towards the expected change. The pooled effect sizes for studies assessing the impact of mass media on similar aspects of care revealed an effect upon the utilisation of health services that could not be explained by chance alone, ranging from -1.96 (95%CI -1. 19 to -2.73) for campaigns promoting immunisation programmes, to -1. 12 (95%CI -0.49 to -2.36) for those concerning cancer screening. REVIEWER'S CONCLUSIONS: Despite the limited information about key aspects of mass media interventions and the poor quality of the available primary research, there is evidence that these channels of communication may have an important role in influencing the use of health care interventions. Those engaged in promoting better uptake of research information in clinical practice should consider mass media as one of the tools that may encourage the use of effective services and discourage those of unproven effectiveness.

Psychosocial combined with agonist maintenance treatments versus agonist maintenance treatments alone for treatment of opioid dependence.

BACKGROUND: Methadone maintenance at proper doses is effective in retaining patients in treatment and suppressing heroin use. Questions remain regarding the efficacy of the psychosocial services that are offered by most maintenance programs. OBJECTIVES: To evaluate the effectiveness of any psychosocial plus any agonist maintenance treatment versus any agonist treatment alone in retaining patients in treatment, reducing the use of substances and improving health and social status. SEARCH STRATEGY: We searched the Cochrane Central Register of Trials (CENTRAL) issue 3, 2003; MEDLINE 1966-2003; EMBASE 1980-2003; PsycINFO 1985-2003; relevant web sites; scan of reference list of relevant articles. There were no language or publication restrictions. SELECTION CRITERIA: RCTs which focus on any psychosocial plus any agonist compared to any agonist maintenance intervention for opiate dependence. People aged less than 18 and pregnant women were excluded. Psychosocial in combination with antagonist maintenance treatment are excluded too. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by the reviewers. Data were extracted independently and double checked. MAIN RESULTS: The searching process resulted in the identification of 77 different studies: 12 studies met the inclusion criteria. These studies considered 8 different psychosocial interventions and 1 pharmacological treatment: Methadone Maintenance (MMT). The results show additional benefit in adding any psychosocial treatment to standard methadone maintenance treatment in relation to the use of heroin during the treatment RR 0.69 (95% CI 0.53-0.91); no statistically significant additional benefit was shown in terms of retention in treatment RR 0.94 (95% CI 0.85-1.02); and results at follow-up RR 0.90 (95% CI 0.76-1.07). REVIEWERS' CONCLUSIONS: The present evidence suggests that adding any psychosocial support to Standard MMT significantly improves the non-use of heroin during treatment. Retention in treatment and results at follow-up are also improved, although this findings did not achieve statistical significance. Insufficient evidence is available on other possible relevant outcomes such as Psychiatric symptoms/psychological distress, Quality of life. Limitations to this review are imposed by the heterogeneity of the trials both in the interventions and the assessment of outcomes. Results of studies were sometimes in disagreement and because of lack of detailed information no meta analysis could be performed to analyse the results related to the outcomes more often reported as positive results in the single studies. Duration of the studies was also too short to analyse other relevant outcomes such as mortality. In order to study the possible added value of any psychosocial treatment over an already effective treatment such as standard MMT, only big multi-site studies could be considered which define experimental interventions and outcomes in the most standardized way as possible.

Psychosocial and pharmacological treatments versus pharmacological treatments for opioid detoxification.

BACKGROUND: Different pharmacological approaches aimed at opioid detoxification are effective. Nevertheless a majority of patients relapse to heroin use, and relapses are a substantial problem in the rehabilitation of dependent heroin users. Some studies have suggested that the sorts of symptoms which are most distressing to addicts during detoxification are psychological symptoms rather than physiological symptoms associated with the withdrawal syndrome. OBJECTIVES: To evaluate the effectiveness of any psychosocial plus any pharmacological interventions versus any pharmacological alone for opioid detoxification, in helping patients to complete the treatment, reduce the use of substances and improve health and social status. SEARCH STRATEGY: We searched the Cochrane Central Register of Trials (CENTRAL) issue 3, 2003; MEDLINE 1966-2003; EMBASE 1980-2003; PsycINFO 1985-2003; relevant web sites; scan of reference list of relevant articles. There were no language or publication restrictions. SELECTION CRITERIA: Randomised controlled trials which focus on any psychosocial associated with any pharmacological intervention aimed at opioid detoxification. People less than 18 years of age and pregnant women were excluded. DATA COLLECTION AND ANALYSIS: The trials were independently assessed for inclusion and methodological quality by three reviewers. Data were extracted independently and double checked. MAIN RESULTS: The searching process resulted in the identification of 77 different studies: 8 studies met inclusion criteria. These studies considered 5 different psychosocial interventions and 2 substitution detoxification treatments: Methadone and Buprenorphine. The results show promising benefit from adding any psychosocial treatment to any substitution detoxification treatment in terms of completion of treatment RR 1.68 (95% CI 1.11-2.55), results at follow-up RR 2.43 (95% CI 1.61-3.66), and compliance RR 0.48 (95% CI 0.38-0.59). In respect of the use of heroin during the treatment, the differences were not statistically significant but favoured the combined treatments. REVIEWERS' CONCLUSIONS: Psychosocial treatments offered in addition to pharmacological detoxification treatments are effective in terms of completion of treatment, results at follow-up and compliance. Although a treatment, like detoxification, that exclusively attenuates the severity of opiate withdrawal symptoms can be at best partially effective for a chronic relapsing disorder like opiate dependence, this type of treatment is an essential step prior to longer-term drug-free treatment and it is desirable to develop adjunct psychosocial approaches that might make detoxification more effective. Limitations to this review are imposed by the heterogeneity of the assessment of outcomes. Because of lack of detailed information no meta analysis could be performed to analyse the results related to several outcomes.

[The systematic review of studies on the efficacy of interventions for the primary prevention of alcohol abuse among adolescents]. / Revisione sistematica degli studi sulla efficacia degli interventi di prevenzione primaria dell'abuso di alcool fra gli adolescenti.

UNLABELLED: Italy finds itself one of the world's leading countries for alcohol consumption. This problem is particularly relevant amongst adolescents. In the past 20 years many preventive interventions of alcohol abuse, addressed to adolescents, have been realized mainly in the United States. PURPOSE OF THE STUDY: To evaluate the effect of educational preventive interventions addressed to youths from 10 to 18 years old on alcohol use. MATERIALS AND METHODS: We have done a systematic review of articles indexed on Medline between 1983 and July 1995. We also consulted the bibliography of the articles retrieved for further references. Randomized controlled trials using alcohol consumption as outcome measure have been included. RESULTS: Of the 100 articles found only 21 were included, in which 27 preventive programs, using 5 different types of intervention, were evaluated. Only 3 resulted effective on all the outcome measures utilized and 6 were partially effective. Overall the methodological quality was low. CONCLUSIONS: The low methodological quality and the great variability of outcome measures utilized made it difficult to compare the results of different studies and impossible to reach definitive conclusions. All the studies were done in the United States and therefore their results cannot be presently generalized to Italy. Consequently, prior to implementing expensive prevention programs in the Italian schools, it would be opportune to perform further well-designed effectiveness trials.

[Impact of mass media on the use of health services. A systematic review of the literature]. / L'effetto dei mass media sull'uso dei servizi sanitari. Una revisione sistematica della letteratura.

BACKGROUND: Mass media may influence the use of health services either through campaigns promoting the use of specific procedures or through the coverage of health related issues outside the context of a planned intervention. To assess their effect on the utilization of health services a systematic overview of primary research was undertaken. METHODS: Experimental and quasi experimental studies meeting pre defined entry criteria and providing information on the impact of mass media on objective measures on health services utilization were searched through Medline, Embase, Psychlit, Eric, as well as handsearching key journals. Data on the detail and content of interventions were abstracted and raw data describing health services utilization obtained. Effect sizes were calculated for each study and then pooled across studies on the same topic using a random effects model. RESULTS: Out of 69 papers providing information on the impact of mass media on aspects of health services utilization, 17 interrupted time series met our quality criteria. Fourteen evaluated the impact of formal mass media campaigns, 3 of media coverage of health related issues. The overall methodological quality was rather variable, with 6 studies not performing any statistical analysis, and 7 using inadequate statistical tests (i.e. not taking into account the effect of time trend). All the studies but the concluded positively on the effect of mass media. These positive findings were confirmed by our re-analysis in 7, while in the remaining the effect of mass media was not statistically significant. The direction of effect was consistent across individual studies and the pooled effect sizes revealed an effect upon the utilization of health services that could not be explained by chance alone, ranging from -1.96 (95% CI: -1.19, -2.73) for campaigns promoting immunization programs, to -1.12 (95% CI: -0.49, -2.46) for those concerning cancer screening. CONCLUSIONS: Despite the overall limited quality of primary research, this review supports the view that these channels of communication may have an important role in influencing the use of health care interventions. Mass media should be considered as one of the tools that may encourage the use of effective services and discourage those of unproved effectiveness.

Experience in Italy in the development and application of clinical guidelines for low back pain.

UNLABELLED: Clinical Guidelines (CG) reflect the up to date scientific knowledge in the treatment of Low Back Pain (LBP). The diffusion of CG and their everyday application by health care professionals is a significant problem. As most CG are developed in English, the concerns are obviously greater in non English-speaking countries. The first CG on LBP by the Quebec Task Force (1987) was introduced in 1990 by the Gruppo di Studio della Scoliosi (GSS). Some studies where planned to verify their everyday application. The first one was carried on in Mantua, and evaluated the assessment of patients by General Practitioners (GPs): there is a clear tendency to over-prescribe examinations in acute cases, while in chronic cases under-prescription is sometimes seen. An educational approach was then proposed through a number of meetings, with fable RESULTS: A third experience verified the help GPs could receive through two different educative interventions such as a booklet and a direct access to a classical Back School. In acute patients a Booklet is useful, while Back School is not; at long term follow-up, chronic cases were significantly reduced only by the Back School approach. Finally, the Abruzzo Study's results on GPs management through computer-assisted evaluation is reported. The second part of the paper deals on the new experiences that are underway on the application of Diagnostic-Therapeutic Pathways (DTP) to Low Back Disorders.

Antonio Ascenzi (1915-2000), a pathologist devoted to anthropology and paleopathology.

Antonio Ascenzi is well known within the scientific community for his original contributions to morbid anatomy and in particular for his studies on the fields of bone biology, bone biomechanics, haematology and congenital heart disease. Additionally, Ascenzi was also interested in human evolution and applied his deep knowledge of pathology to ancient human remains, conducting research in paleoanthropology on fossilized Neanderthal specimens found in Italy. The name of Ascenzi is linked with the discovery and study of the most ancient Italian bone fossils, namely the Ceprano skull, an early specimen of Homo erectus. Furthermore, his pioneering researches on the Uan Muhuggiag and Grottarossa mummies and his rigorous studies on several aspects and problems concerning the pathologies of past human populations made him a pioneer in the fields of Italian mummiology and paleopathology. The thread that linked his diversified research interests outside and within human anthropology was a profound passion for the search and discovery of scientific truth.
