Journal of Rafsanjan University of Medical Sciences JRUMS 1735-3165 2008-7268 10.61186/jrums 2013 12 2 How to report systematic reviews and meta- analyses M. Rezaeian moeygmr2@yahoo.co.uk   سخن سردبیر   Editorial   مجله دانشگاه علوم پزشکی رفسنجان   دوره دوازدهم، اردیبهشت 1392، 88-87     چگونه مقالات مروری منظم و فرا تحلیل‌ها را گزارش کنیم   How to report systematic reviews and meta-analyses     محسن رضائیان [1]   M. Rezaeian     تعداد مقالات پژوهشی اصیل که در حوزه‌های گوناگون معرفت بشری و به‌ویژه در حوزه سلامت به رشته تحریر در می‌آیند، با سرعت شتابانی افزایش می‌یابند. برای نمونه فقط برآورد می‌گردد که موتور جستجوی مدلاین MEDLINE سالانه حدود 600000 مقاله جدید را نمایه می‌کند. از همین رو، برای متخصصان یک رشته خاص، مطالعه و جمع‌بندی همه مقالات منتشر شده در حوزه تخصصیشان کاری بسیار دشوار می‌باشد [1]. در پاسخ به این نیاز مهم، دانشمندان، مطالعات مروری منظم (Systematic review studies) و فرا تحلیل‌ها (Meta-analyses) را طراحی نموده‌اند. در این نوع مطالعات، گروه تحقیق نسبت به تدوین یک پروتکل، بر اساس یک سؤال مشخص اقدام می‌نمایند که در آن، به ‌دقت چگونگی جمع‌آوری، تجزیه و تحلیل و جمع‌بندی مقالات در یک قلمرو خاص از دانش بشری مشخص شده است. در صورتی که جمع‌بندی نتایج به صورت کیفی ( Qualitative ) گزارش گردد، نوع مطالعه مروری منظم و در صورتی‌که جمع‌بندی نتایج به صورت کمّی ( Quantitative ) گزارش گردد، نوع مطالعه فراتحلیل خواهد بود [2].   مطالعات مروری منظم و فرا تحلیل‌ها نیز ممکن است، مانند هر نوع طراحی مطالعه دیگر به شکلی ضعیف طراحی و اجرا شوند، لذا دستورالعمل‌های خاصی برای چگونگی گزارش چنین مطالعاتی در نظر گرفته شده است. برای نمونه، در سال 1996 میلادی یک گروه بین‌المللی از دانشمندان، دستورالعملی را برای گزارش فراتحلیل‌ها طراحی نمودند که به‌‌عنوان بیانیه کواروم [( (QuoRom Statement) (Quality of Reporting of Meta-analyses ] شناخته شد [3]. این بیانیه فقط مختص چگونگی گزارش یک فراتحلیل به ‌عمل آمده بر روی کارآزمایی‌های تصادفی شاهددار ( Randomized Controlled Trials ) تهیه شده بود. از همین رو، بازنگری این بیانیه به ویژه به منظور در بر گرفتن مطالعات مروری منظم ضروری بود. از همین رو، گروهی از دانشمندان متخصص فعالیت خود را بر روی بیانیه کواروم متمرکز نموده و نتایج کار خود را در سال 2009 میلادی با عنوان بیانیه پریزما [ (Performed Reporting Items for Systematic reviews and Meta-analyses) ( PRISMA Statement )] منتشر نمودند [5-4]. از خصوصیات بیانیه جدید آن است که در آن علاوه بر فراتحلیل‌ها، چگونگی گزارش استاندارد مطالعات مروری منظم نیز در نظر گرفته شده است. همچنین، اگر چه مرکز تمرکز این بیانیه نیز بر روی جمع‌بندی کارآزمایی‌های تصادفی شده شاهددار می‌باشد، اما تدوین‌کنندگان این بیانیه معتقدند که می‌توان آن را برای جمع‌بندی سایر مطالعات نیز بکار برد.   بیانیه پریزما دارای یک چک ‌لیست 27 آیتمی است که در آن چگونگی نگارش عنوان، خلاصه، روش‌ها، نتایج، بحث و حتی منبع تأمین‌کننده بودجه مطالعه مورد سؤال قرار گرفته است. همچنین، این بیانیه دارای یک فلودیاگرام ( (Flow-diagram چهار مرحله‌ای است که در آن به ‌دقت چگونگی پیدا کردن، غربالگری، دستیابی به مقالات مرتبط و جمع‌بندی آن‌ها مورد پرسش قرار گرفته است.   با توجه به اینکه انجام مطالعات مروری منظم و فرا تحلیل‌ها [5] در کشور ما نیز در حال افزایش است و مجله دانشگاه علوم پزشکی رفسنجان مانند سایر مجلات علوم پزشکی کشور در هر سال تعداد زیادی از این مقالات راجهت چاپ دریافت می‌کند، ضرورری است که محققین محترم قبل از انجام هرگونه مطالعه مروری منظم یا فراتحلیل، ازمفاد بیانیه پریزما و کاربرد دقیق آن در طراحی مطالعه خود اطمینان لازم را کسب نمایند تا مقاله حاصل از کار آنها با اقبال در انتشار روبرو گردد. لازم به توضیح است که علاوه بر منابع شماره 4 و 5 ذکر شده در این سخن سردبیری که به تشریح بیانیه پریزما می‌پردازد، این بیانیه دارای یک وب سایت مشخص است که در بهار سال 1392 آدرس آن ( http//www.prisma-statment.org/ ) می‌باشد.     References   [1] Chung KC, Shauver MJ.

Vazirinejad M. Rezaeian mrezaeian@yahoo.co.uk M. Taghavi   Background and Objectives: Final corrections on a manuscript sent for publication in a scientific journal are suggested by reviewers. So this qualifies the paper with the least errors for publication. The present study aimed to assess the Persian language peer reviewers' comments on a manuscript sent to an Iranian Scientific Journal (journal of Rafsanjan university of medical sciences), 2010.   Materials and Methods: In this descriptive study, a manuscript which was sent to a scientific journal for publication was sent to 30 peer reviewers to obtain their comments. This approach was the routine method of the journal in peer reviewing the manuscripts. When peer reviewers' comments come back to the editorial office, a trained expert recorded the information on an anonymous checklist. The checklist included a list of nine items which were expected to be reported by peer reviewers as their comments. Data were analyzed using SPSS.   Results: Fourteen respondents (about 50%) sent their comments back in due date. Of these, five were affiliated with other universities and nine were affiliated to the journal university. Nine were female (64%) and 5 were males (%35/7). With one exception, peer reviewers inside the journal university were more successful than peer reviewers outside the journal university in distinguishing the other eight general items. No a peer reviewer reported all of the nine items. Among the nine items, "sample size" was reported by the highest proportion (64%) of peer reviewers.   Conclusion: Peer reviewing should be improved among peer reviewers of the scientific journal of this study and proper interventions should be conducted. More investigations are needed to cover more scientific journals and more peer reviewers.   Key words: Precision, Peer Reviewer, Scientific, Journal, Manuscripts     Funding: This research was funded by Rafsanjan University of Medical Sciences, Occupational Environment Research Centre .   Conflict interest: None declared.   Ethical approval: The Ethics Committee of Rafsanjan University of Medical Sciences.     How to cite this article : Vazirinejad R, Rezaeian M, Taghavi M.

Allahtavakili m_alahtavakoli@rums.ac.ir   Background and Objectives: Diarrhea is one of the worldwide health problems and one of the most common causes of childrens’ mortality. In the present experiment, effect of Descurainia sophia on castor oil-induced diarrhea was investigated.   Materials and Methods: In this experimentd study 24 male rats were randomly divided into 4 groups as follows: Descurainia sophia with doses of 400 and 600 mg/kg Diphenoxylate 0.5 mg/kg and control (vehicle). One hour after orally receiving the drugs or vehicle (normal saline 10 ml/kg), each animal was given castor oil (2 ml/rat) by an oro-gastric catheter. Then the rats were placed in a separate cage and observed for 5 h defecation to determine fecal quality, frequency, and weight. Data were analyzed by one-way ANOVA followed by Tukey test and p<0.05 was considered as significant difference.   Results: Both Descurainia sophia 600, 400 (mg/kg) and Diphenoxylate attenuated the percentage of weight loss (p<0.005). Compared to the control group, Descurainia sophia 600 and Diphenoxylate (p<0.005) and Descurainia sophia 400 (p<0.05) decreased the total excretion. Also compared to the control group, Descurainia sophia 600 and 400 (mg/kg) decreased stool weight (p<0.05).   Conclusions: Extract of Descurainia sophia plant has the same effect as Diphenoxylate on attenuating castor oil - induced diarrhea symptoms and also reduction of fecal water content.   Key words: Diarrhea, Descurainia sophia, castor oil, Rat   Funding: This research was funded by Rafsanjan University of Medical Sciences.   Conflict of interest: None declared.   Ethical approval: The Ethical Committee of Rafsanjan University of Medical Sciences approved the study. .     How to cite this article : Ayoobi F, Kamali B, Shamsizadeh A, Sajadi MA, Roohbakhsh A, Vazirinejad R, Hakimi E, Rezazadeh HA, Rahmani MR, Allahtavakili M .
