Reasons for irregular use of ferrous sulfate tablet in women referred to health centers in Bourojen city, 2005-2006

چکیده: زمینه و هدف: خانم های باردار و شیرده از جمله گروههای در معرض خطر ‌کم خونی فقر آهن می باشند. با وجود برنامه مدون در ارتباط با مصرف قرص آهن توسط مادران، آمار به دست آمده نشان میدهد حدود 67 درصد زنان باردار و شیرده قرص آهن را صحیح و منظم مصرف نمی کنند. لذا این مطالعه با هدف بررسی علل مصرف نامنظم قرص آهن در خانم های باردار و شیرده مراجعه کننده به مراکز بهداشتی درمانی شهر بروجن انجام شد. روش بررسی:در این مطالعه توصیفی – تحلیلی که در مراکز بهداشتی درمانی شهر بروجن در سال 85-1384 انجام گرفت، 270 نفر خانم که در دوره 16 هفتگی حاملگی الی 2 ماهگی پس از زایمان قرار داشتند به روش دردسترس انتخاب و طی مصاحبه حضوری به سؤالات پرسشنامه حاوی اطلاعات دموگرافیک، چگونگی مصرف قرص آهن، نگرش و عملکرد مادران در این خصوص پاسخ دادند. از آزمونهای کای دو، من ویتنی و ویلکاکسون و کروسکال والیس جهت تجزیه و تحلیل آْماری اطلاعات استفاده شد. یافته ها: نتایج نشان داد که 1/33 مادران قرص آهن را مرتب و منظم مصرف می کردند، 8/56 نامنظم و 2/10 اصلا مصرف نمی‌کردند. بین مصرف نامنظم قرص آهن و سطح اقتصادی - اجتماعی خانواده و تعداد زایمان ارتبــاط معنی داری وجود نداشت. از علل مصرف نامنظم قرص آهن 4/48 مادران فراموش کردن وعده های مصرف دارو، 4/12 تهوع و استفراغ حاملگی و 4/16 عدم آگاهی نسبت به لزوم مصرف آهن را ذکر کردند. بین تعداد زایمان و یا حاملگی، سن فرد و شاغل بودن با آگاهی، نگرش و عملکرد آنان ارتباط معنی دار وجود نداشت (05/0

Chelating and Bridging Roles of 2-(2-Pyridyl)benzimidazole and Bis(diphenylphosphino)acetylene in Stabilizing a Cyclic Tetranuclear Platinum(II) Complex.

The reaction of complex [Pt(Me)(DMSO)(pbz)], 1, (pbz = 2-(2-pyridyl)benzimidazolate) with [PtMe(Cl)(DMSO)2], B, followed by addition of bis(diphenylphosphino)acetylene (dppac), gave the novel tetranuclear platinum complex [Pt4Me4(μ-dppac)2(pbz)2Cl2], 2, bearing both the pbz and dppac ligands. In this structure, the pbz ligands are both chelating and bridging to stabilize the tetraplatinum framework. The tetranuclear Pt(II) complex was fully characterized by NMR spectroscopy, X-ray crystallography, and mass spectrometry, and its electronic structure was investigated and supported by DFT calculations

The effect of an exercise program on the health-quality of life in older adults

INTRODUCTION: An essential public health goal is to reduce age-related disabilities in the elderly. The present study aimed to investigate the effect of exercise program on health-quality of life (HQL) in older adults. METHODS: Subjects were sixty healthy adult volunteers over the age of �� years. None of the subjects had any experience in exercise programs but were physically active and able to perform activities of daily living independently. The subjects were randomly assigned into one of two groups each with �� people: test (exercise) group and control (no exercise) group. The test group was taken into a � - week aerobic exercise program. The exercises included a �- �� minute circulatory warm-up, a �� minute walking and a �-�� minute stretching/cool-down period. The exercises were performed three times per week under supervision of an experienced instructor. No exercise program was prescribed for the control group. Both groups were assessed before and after the exercise program. The LEIPAD questionnaire was used to measure HQL. RESULTS: The results showed significant improvements in all domains of the LEIPAD questionnaire whilst the level of HQL did not change and none of the scores obtained by the LEIPAD was significant. Measures of HQL improved with exercise so that there were no HQL changes in the control but significant changes were observed in the exercise group. CONCLUSION: This study suggests that an exercise program has resulted in a signific

Factors related to absenteeism of nurses at hospitals affiliated with Tehran Medical University

Background and aimAbsenteeism cause many problems for managers and other personnel especially nursing staff and leads to decreased quality and quantity of nursing care and, ultimately, health level of society. This descriptive study was conducted to determine the related factors of absenteeism in nursing staff at hospitals affiliated with Tehran Medical University.  Materials and methods105 registered nurses with at least 1 event of absenteeism at different healthcare centers of Imam Khomeini Hospital were randomly selected. A questionnaire in 3 parts including items for demographics, related factors of absenteeism and an open question asking about the ways to reduce it was used for data collection.Content and test-retest methods were used for validity and reliability of the tool respectively (r=0/87). Such statistical tests as Chi-square and t-student were used for data analysis. FindingsMost subjects (9.82%) was between 26-39 (mean age=4.30±1.18); 6.78%, women; 6.88%, baccalaureate; 3.74%, married; 1.57% with rental residence and 4.71% with shift rotation. 5.65% considered therapeutic problems as the most effective factor in absenteeism, of which 9.83% named tiredness from work as a reason for them. A significant correlation was found between absenteeism and age as well as sex (

Ligand-Mediated C-Br Oxidative Addition to Cycloplatinated(II) Complexes and Benzyl-Me C-C Bond Reductive Elimination from a Cycloplatinated(IV) Complex.

Reaction of the Pt(II) complexes [PtMe2(pbt)], 1a, (pbt = 2-(2-pyridyl)benzothiazole) and [PtMe(C^N)(PPh2Me)] [C^N = deprotonated 2-phenylpyridine (ppy), 1b, or deprotonated benzo[h]quinoline (bhq), 1c] with benzyl bromide, PhCH2Br, is studied. The reaction of 1a with PhCH2Br gave the Pt(IV) product complex [PtBr(CH2Ph)Me2(pbt)]. The major trans isomer is formed in a trans oxidative addition (2a), while the minor cis products (2a' and 2a″) resulted from an isomerization process. A solution of Pt(II) complex 1a in the presence of benzyl bromide in toluene at 70 °C after 7 days gradually gave the dibromo Pt(IV) complex [Pt(Br)2Me2(pbt)], 4a, as determined by NMR spectroscopy and single-crystal XRD. The reaction of complexes 1b and 1c with PhCH2Br gave the Pt(IV) complexes [PtMeBr(CH2Ph)(C^N)(PPh2Me)] (C^N = ppy; 2b; C^N = bhq, 2c), in which the phosphine and benzyl ligands are trans. Multinuclear NMR spectroscopy ruled out other isomers. Attempts to grow crystals of the cycloplatinated(IV) complex 2b yielded a previously reported Pt(II) complex [PtBr(ppy)(PPh2Me)], 3b, presumably from reductive elimination of ethylbenzene. UV-vis spectroscopy was used to study the kinetics of reaction of Pt(II) complexes 1a-1c with benzyl bromide. The data are consistent with a second-order SN2 mechanism and the first order in both the Pt complex and PhCH2Br. The rate of reaction decreases along the series 1a ≫ 1c > 1b. Density functional theory calculations were carried out to support experimental findings and understand the formation of isomers
