Prevalence of cocaine use and cocaine use disorder among adult patients with attention-deficit/hyperactivity disorder: A systematic review and meta-analysis.

We conducted this systematic review and meta-analysis (registered with PROSPERO CRD42020142039) of the literature to estimate the lifetime prevalence of cocaine use and cocaine use disorder among adult patients with attention-deficit/hyperactivity disorder (ADHD). The literature search was performed on the electronic databases PubMed and PsychINFO without date or language restrictions. Additional studies were identified by hand searching of citations. Inclusion criteria were: studies involving adult patients with ADHD and reporting cocaine use and/or cocaine use disorders. Data were pooled in the meta-analyses using a generalized linear mixed model with random effects. Statistical heterogeneity was assessed using the Cochran Q test. Sensitivity analyses were conducted. Twelve studies were included in the review: six in the meta-analysis of cocaine use and nine in the meta-analysis of cocaine use disorder. The estimated prevalence of cocaine use was 26.0% (95% CI 0.18-0.35) and the estimated prevalence of cocaine use disorder was 10.0% (95% CI 0.08-0.13). Heterogeneity in both meta-analyses was high but decreased to non-significance in the meta-analysis on cocaine use disorder after excluding the outlier study. In conclusion, one out of four adult patients with ADHD use cocaine and one out of ten develop a lifetime cocaine use disorder. Since cocaine use can lead to more severe and complex disorders of impaired systemic functioning, adult patients with ADHD should be assessed for cocaine use disorder and promptly referred for treatment.

Outcomes of integrated management versus specialized care for patients with type 2 diabetes: An observational study.

AIMS: To compare type 2 diabetes (T2D) patients included in a Diabetes Integrated Management (DIM) program with those followed in Diabetes Specialized Care (DSC), investigating differences in general characteristics, changes in clinical outcomes, and factors related with the inclusion in the DIM program. METHODS: T2D patients living in the ASLTO3 district and included into the DIM program, a shared disease management between general practitioners and diabetes specialists, from 2008 to 2014 were compared with T2D patients living in the same district and in charge of the local DSC. Demographic, anthropometric and clinical data for both groups of patients were obtained from the electronic records of DSC. RESULTS: 1326 DIM patients were compared with 3494 DSC patients. A higher proportion of females was observed among DIM patients than among DSC patients. DIM patients were older, more frequently in therapy with diet only or with oral hypoglycemic, and had HbA1c and creatinine lower than DSC patients. The analyses of changes in clinical parameters during the study period showed a good and statistically significant improvement of most parameters, independently of the inclusion in DIM or DSC, with the exception of creatinine level. CONCLUSIONS: Integrated Management is an efficient and effective way to achieve good long-term clinical outcomes for patients with diabetes.

School-based prevention for illicit drugs' use.

BACKGROUND: Drug addiction is a chronic, relapsing disease. Primary interventions should be aimed to reduce first use, or prevent the transition from experimental use to addiction. School is the appropriate setting for preventive interventions. OBJECTIVES: To evaluate the effectiveness of school-based interventions in improving knowledge, developing skills, promoting change, and preventing or reducing drug use versus usual curricular activities or a different school-based intervention . SEARCH STRATEGY: MEDLINE , EMBASE, ERIC, PSYCHINFO, Cochrane Library, ACP Journal Club, Cochrane Drug and Alcohol Group Register, updated to February 2004, were searched. Bibliography of papers was checked and personal contacts were made to identify other relevant studies. SELECTION CRITERIA: RCTs, CCTs or Controlled Prospective Studies (CPS) evaluating school-based interventions designed to prevent substance use. DATA COLLECTION AND ANALYSIS: Data were selected and extracted independently by two reviewers. Quality was assessed with the CDAG checklist. Interventions were classified as skills, affective, knowledge-focused and other characteristics were also studied (teaching, follow-up implementation, context activation). MAIN RESULTS: 32 studies (29 RCTs and 3 CPSs) were included. 28 were conducted in the USA; most were focused on 6th-7th grade students, and based on post-test assessment. RCTs: (1) Knowledge vs usual curricula: Knowledge focused programs improve drug knowledge (SMD=0.91; 95% CI: 0.42, 1.39).(2) Skills vs usual curricula: Skills based interventions increase drug knowledge (WMD=2.60; 95% CI: 1.17-4.03), decision making skills (SMD=0.78; CI95%: 0.46-1.09), self-esteem (SMD=0.22; CI95%: 0.03-0.40), peer pressure resistance (RR=2.05; CI95%: 1.24-3.42), drug use (RR=0.81; CI95%: 0.64, 1.02), marijuana use (RR=0.82; CI95%: 0.73, 0.92) and hard drug use (RR=0.45; CI95%: 0.24-0.85). (3) Skills vs knowledge: No differences are evident.(4) Skills vs affective: Skills-based interventions are only better than affective ones in self-efficacy (WMD=1.90; CI95%: 0.25, 3.55). (5) Affective vs usual curricula: Affective interventions improve drug knowledge (SMD=1.88; CI95%: 1.27, 2.50) and decision making skills (SMD=1.35; CI95%: 0.79, 1.9). (6) Affective vs knowledge: Affective interventions improve drug knowledge (SMD=0.60; CI95%: 0.18,1.03), and decision making skills (SMD=1.22; CI95%: 0.33, 2.12). Results from CPSs: No statistically significant results emerge from CPSs. AUTHORS' CONCLUSIONS: Skills based programs appear to be effective in deterring early-stage drug use. The replication of results with well designed, long term randomised trials, and the evaluation of single components of intervention (peer, parents, booster sessions) are the priorities for research. All new studies should control for cluster effect.

Tuberculosis incidence in Turin, Italy, 1973-1999.

SETTING: Turin, Italy, 1973-1999. OBJECTIVE: To estimate tuberculosis (TB) incidence rates in Turin between 1973 and 1999. DESIGN: Incidence study. An active search of new TB cases was carried out by examining the clinical records of the three major TB care services in the city. New cases were defined as patients treated for the first time. To evaluate the completeness of this series, data were linked with the TB Notification Register and the Regional Hospital Discharges Register for the years 1997-1999. RESULTS: TB incidence rates declined from 25.6 cases per 100,000 population in 1973 to 6.4 in 1999. TB/human immunodeficiency virus (HIV) co-infection increased after 1985, reaching a peak (16.5%) in 1994-1996, and significantly decreasing in 1997-1999. Foreign-born cases started to increase after 1988, reaching 25.8% of total cases in 1997-1999. TB infections in Italian-born, non-HIV-infected cases occurred mostly among the elderly, while HIV/TB co-infections and TB in immigrants occurred mostly in younger age groups. The study captured 59% of cases diagnosed in Turin in 1997-1999. CONCLUSIONS: In recent years, new cases of TB have been diagnosed mostly among HIV-positive people and immigrants. Preventive and control strategies should focus on these population groups, improving quick identification and effective treatment of cases, and implementing accessible services.
