Background: To date, little is known about the characteristics of highly cited studies in hand surgery compared with other orthopaedic subspecialties. We aimed to assess the position of hand surgery within the orthopedic surgery literature. Methods: We conducted a bibliographic analysis using the Web of Science database to review 1,568 articles published between January 2012 and December 2012 in 4 relevant general orthopedic and 2 hand surgery journals. We used the number of citations within 3 years of publication to measure the impact of each paper. To analyze prognostic factors using logistic regression analysis, we extracted data on orthopedic subspecialty, published journal, location of authorship, and type of study for all articles. For clinical studies, we also recorded details on study design and sample size. Results: Of eligible hand surgery articles (n = 307), the majority (62%) were case reports/series. Only 19% were comparative studies, comprising a significantly smaller proportion of comparative studies from other subspecialties in general orthopedic journals. Systematic reviews/meta-analyses generated a significantly higher number of average citations, whereas educational reviews were consistently cited less frequently than other study types (14.9 and 6.1 average citations, respectively). Being published in the Journal of Bone and Joint Surgery, American volume, having authorship in North America or Europe and Australia, focusing on subspecialties like hip & knee, sports, or shoulder, utilizing a comparative or randomized clinical trial study design, and having a larger sample size increased the odds of receiving more citations. Conclusions: Clinical studies related to hand surgery published in general orthopedic journals are most often of lower quality study design. Having a larger sample size or using a comparative study or randomized clinical trial design can improve the quality of study and may ultimately increase the impact factor of hand surgery journals.

This article provides an analysis of the results of a large international randomized clinical trial PLATO, in which to learn a new antiplatelet ticagrelor compared with clopidogrel in addition to aspirin in patients with acute coronary syndrome (ACS). Material contains a description of the study design, the main results concerning the efficacy and safety of ticagrelor. In addition, the material presented those parts of modern clinical practice guidelines, which describes the location of ticagrelor in the treatment of ACS and which are modified according to a PLATO study.

AbstractVarious approaches are considered for adjustment of clinical trial size for patient noncompliance. Such approaches either model the effect of noncompliance through comparison of two survival distributions or two simple proportions. Models that allow for variation of noncompliance and event rates between time intervals are also considered. The approach that models the noncompliance adjustment on the basis of survival functions is conservative and hence requires larger sample size. The model to be selected for noncompliance adjustment depends upon available estimates of noncompliance and event rate patterns.

In a recent randomized clinical trial, Wennerholm and colleagues compared induction of labour at 41 weeks with expectant management and induction at 42 weeks. The trial was stopped early, because six perinatal deaths occurred in the expectant management group, whereas none occurred in the induction group. Our Bayesian reanalysis finds that the SWEPIS data indeed support the hypothesis that induction of labour at 41 weeks of pregnancy is associated with a lower rate of stillbirths. However, the degree of this support is moderate at best, and arguably provides insufficient ground for terminating the study. In general, it seems hazardous to terminate clinical studies on the basis of a single P<0.05 result, without converging support of a Bayesian analysis.

Objective. Although the role of oxidative stresses has been confirmed in the pathophysiology of allergic rhinitis and the protective effect of silymarin against oxidative stresses has been proven in different organs, no study has yet been conducted on the impact of silymarin on allergic rhinitis treatment. Study Design. A randomized clinical trial study. Setting. Two tertiary referral centers with otorhinolaryngology–head and neck surgery and allergy and immunology departments. Patients and Methods. In a randomized clinical trial, 94 patients with the signs and symptoms of allergic rhinitis and a positive skin prick test were selected and randomly divided into 2 groups. Their signs and symptoms, eosinophil percentage on nasal smear, serum IgE, and interleukin (IL-4, IL-5, interferon-γ) levels were recorded. The study group was treated with silymarin, whereas the control group received placebo, both for 1 month, along with routine antihistamine treatment. At the end of the treatment course, clinical and laboratory findings were statistically analyzed. Results. Sixty patients completed the trial. Based on the Sino-Nasal Outcome Test 20 (SNOT-20), a significant improvement in clinical symptom severity was observed in both groups (9.23 ± 5.14 vs 2.20 ± 2.69; P < .001), which was statistically significantly higher in the study group ( P < .001). Posttreatment percentage of nasal eosinophils and cytokine levels showed no significant difference ( P > .05). Rise in serum IgE level was seen after treatment with silymarin ( P = .003). Conclusion. Considering the statistically effective role of silymarin in alleviating the severity of allergic rhinitis symptoms, applying this herbal antioxidant along with other medications may result in better management.
