To assess levels of adherence to national prescribing guidelines and awareness of changes in the efficacy and safety data published in the profiles of medications for the treatment of PD, we have reviewed studies on patterns and determinants of prescribing PD medications conducted in the last 50 years (since the discovery of L-dopa). A systematic literature review was conducted using EMBASE (1967 to March, 2018), Ovid MEDLINE(R) ALL (1967 to March 16, 2018), PsycINFO (1967 to the 2<sup>nd</sup> week of March, 2018), and PubMed to identify all studies measuring prescribing patterns of PD medication between 1967 and 2017. Study design, source of data, country, year of study, number of patients and/or prescriptions, unit of analysis, prescribing determinants, and percentage utilisation of PD medications were extracted where possible. 44 studies examining prescribing patterns and/or prescribing determinants across 17 countries were identified. Unsurprisingly, L-dopa was the most commonly prescribed medication in all studies, accounting for 46.50% to 100% of all prescriptions for PD. In several studies, the prescribing rate of ergot-derived dopamine agonists (DAs) decreased over time in concordance with guidance. In contrast, the prescribing rates of non-ergot DAs increased over the last ten years in most of the included studies. In examining prescribing factors, two major categories were exemplified, patients' factors and prescribers' factors, with patients' age being the most common factor that affected the prescription in most studies. In conclusion, L-dopa is now the most commonly prescribed medication for cases of PD but there is large variation in the prescribing rates of catechol-O-methyltransferase (COMT) inhibitors, monoamine oxidase B (MAO-B) inhibitors, amantadine, and anticholinergics between countries. New studies examining the effects of recent clinical trials and measuring the prescribing rates of newly approved medications are warranted.</p>","PeriodicalId":20853,"journal":{"name":"Regulatory Peptides","volume":"37 1","pages":"9237181"},"PeriodicalIF":6.7,"publicationDate":"2019-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6875178/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75159795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The major goals of treatment are to relieve pain, reduce inflammation, slow down or stop joint damage, prevent disability, and preserve or improve the person's sense of well-being and ability to function. Tai Chi, interchangeably known as Tai Chi Chuan, is an ancient Chinese health-promoting martial art form that has been recognized in China as an effective arthritis therapy for centuries. This is an update of a review published in 2004.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;To assess the benefits and harms of Tai Chi as a treatment for people with rheumatoid arthritis (RA).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Search methods: &lt;/strong&gt;We updated the search of CENTRAL, MEDLINE, Embase, and clinical trial registries from 2002 to September 2018.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Selection criteria: &lt;/strong&gt;We selected randomized controlled trials and controlled clinical trials examining the benefits (ACR improvement criteria or pain, disease progression, function, and radiographic progression), and harms (adverse events and withdrawals) of exercise programs with Tai Chi instruction or incorporating principles of Tai Chi philosophy. We included studies of any duration that included control groups who received either no therapy or alternate therapy.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Data collection and analysis: &lt;/strong&gt;We used standard methodological procedures expected by Cochrane.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Main results: &lt;/strong&gt;Adding three studies (156 additional participants) to the original review, this update contains a total of seven trials with 345 participants. Participants were mostly women with RA, ranging in age from 16 to 80 years, who were treated in outpatient settings in China, South Korea, and the USA. The majority of the trials were at high risk of bias for performance and detection bias, due to the lack of blinding of participants or assessors. Almost 75% of the studies did not report random sequence generation, and we judged the risk of bias as unclear for allocation concealment in the majority of studies. The duration of the Tai Chi programs ranged from 8 to 12 weeks.It is uncertain whether Tai Chi-based exercise programs provide a clinically important improvement in pain among Tai Chi participants compared to no therapy or alternate therapy. The change in mean pain in control groups, measured on visual analog scale (VAS 0 to 10 score, reduced score means less pain) ranged from a decrease of 0.51 to an increase of 1.6 at 12 weeks; in the Tai Chi groups, pain was reduced by a mean difference (MD) of -2.15 (95% confidence interval (CI) -3.19 to -1.11); 22% absolute improvement (95% CI, 11% to 32% improvement); 2 studies, 81 participants; very low-quality evidence, downgraded for imprecision, blinding and attrition bias.There was very low-quality evidence, downgraded for, blinding, and attrition, that was inconclusi","PeriodicalId":20853,"journal":{"name":"Regulatory Peptides","volume":"1 1","pages":"CD004849"},"PeriodicalIF":8.8,"publicationDate":"2019-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6759565/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75604586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
