Sexually Transmitted Infection Among Adolescents and Young Adults with Autism Spectrum Disorder: A Nationwide Longitudinal Study.

The association between autism spectrum disorder (ASD) and subsequent sexually transmitted infections (STIs) and the potential effects of medications on STI risk remain unknown. In all, 5076 adolescents and young adults with ASD and 57,060 age-/sex-matched individuals without ASD were enrolled between 2001 and 2009 and followed-up to the end of 2011 for identification of subsequent STIs. The results revealed that patients with ASD were prone to acquiring an STI [hazard ratio (HR) 3.36] compared with the comparison group. Long-term use of atypical antipsychotics was associated with a lower risk of acquiring an STI later in life compared with nonuse (HR 0.34). We recommend that clinicians closely monitor risky sexual behaviors and STI risk in patients with ASD.

Mortality Risk of Atypical Antipsychotics for Behavioral and Psychological Symptoms of Dementia: A Meta-Analysis, Meta-Regression, and Trial Sequential Analysis of Randomized Controlled Trials.

BACKGROUND: Evidence suggests that atypical antipsychotics (AAPs) exert a short-term mortality risk in people with dementia. We assessed whether additional randomized clinical trials influence the current evidence and the potential effect modifiers. METHODS: Electronic databases were systematically searched for randomized controlled trials from their inception through March 2018. A random-effects model was used for analysis. Potential effect modifiers were examined through meta-regression. Trial sequential analysis was performed to quantify the statistical reliability of data in the cumulative meta-analysis with adjustment of significance levels for sparse data and repetitive testing on accumulating data. Certainty of evidence and risk of bias were also evaluated. RESULTS: We found that compared with placebos, AAPs may increase the risk of mortality (odds ratio [OR], 1.536; 95% confidence intervals [CIs], 1.028-2.296; P = 0.036, high certainty). In the subgroup analysis, the estimated ORs were the highest for olanzapine (1.919; P = 0.232), followed by those for quetiapine (1.663; P = 0.506), aripiprazole (1.649; P = 0.297), and risperidone (1.354; P = 0.277); however, the mortality risk presented by individual AAPs did not exhibit between-group differences. The meta-regression did not identify any effect modifiers, including the chlorpromazine equivalent dose, trial duration, and cognitive status. The trial sequential analysis revealed that future similar trials are unlikely to alter our findings. CONCLUSIONS: Atypical antipsychotics are associated with increased short-term mortality risk, although a disease-drug interaction may contribute to such risk in people with dementia. Patients with dementia may still benefit by AAPs after appropriate assessment of the disease severity as well as the dosage of AAPs, treatment duration, and monitoring of AAPs.

Effects of different pharmacologic smoking cessation treatments on body weight changes and success rates in patients with nicotine dependence: A network meta-analysis.

Smoking cessation is a public health priority to reduce smoking-related morbidity and mortality. However, weight gain is a known primary reason for not trying to quit smoking. The aim of the current study was to investigate differences in weight gain associated with different pharmacological smoking cessation interventions. Randomized controlled trials (RCTs) that reported weight gain related to pharmacologic treatments for smoking cessation were analysed using network meta-analysis with a random effects model. Thirty-one RCTs with 5650 participants were included. Ten drugs and 22 regimens were identified. Nicotine patches plus fluoxetine, topiramate with/without nicotine patches, nicotine patches plus methylphenidate, nicotine spray/gum/lozenges, high-dose nicotine patches (42 mg/21 mg), naltrexone with/without nicotine patches, or bupropion with/without nicotine patches were associated with less weight gain than the placebo/control arm. Nicotine patches plus fluoxetine were associated with the least weight gain of all smoking cessation treatments. In addition, the nicotine patch plus topiramate and nicotine inhaler was associated with the best success rate and the least dropout rate, respectively. Overall, the nicotine patch 14 mg plus fluoxetine 40 mg, nicotine patch 14 mg plus fluoxetine 20 mg, and topiramate 200 mg would be the three best pharmacologic treatments based upon both weight gain effect and success rate.
