Struggling to create new boundaries: a grounded theory study of collaboration between nurses and parents in the care process in Iran.

AIM: To develop a substantive grounded theory of nurse-mother interaction in the care of chronically ill children in hospital setting. BACKGROUND: Interaction between nurses and parents is critical in paediatric hospital settings. This area of practice in developing countries has been under-researched. METHOD: The qualitative research design of grounded theory methodology was used to develop a theory of nurse-parent interaction within the child care. Registered Nurses (n=17) and mothers of chronically ill children (n=14) from two central paediatric hospital in Iran participated in this study. In-depth interviews with nurses and mothers were conducted using theoretical sampling between July 2007 and August 2008. The data were analysed using constant comparative analysis. FINDINGS: 'Struggling to create new boundaries' as a core variable was a dominant socio-psychological process that was manifesting itself within three stages: facing up to and perceiving the environmental pressures, balancing nurse's duties, and controlling the nurse-parent boundary in the care. CONCLUSION: It is concluded that nurses and parents need a care model, which addresses their collaboration and improved interpersonal relationship and clearly defines the boundary of their roles based on the needs of both sides while allowing parents to choose their role in these defined boundaries and providing parent education with aim to empower them for care at home

The effect of Nurse-parent collaboration Model on mother's satisfaction

زمینه و هدف: علیرغم توافق جهانی در خصوص اهمیت مشارکت خانواده در مراقبت، معنای آن دچار ابهام است. در مطالعه حاضر، محقق به تعیین تأثیر بکارگیری مدل مشارکت پرستار-والد بر میزان رضایت مادران از مراقبت پرداخته است. روش بررسی: مطالعه حاضر از نوع مداخله‌ای با طراحی تحقیق نیمه تجربی دو گروهی بود که در مرکز طبی کودکان تهران انجام گرفت. ابتدا در یک دوره 3 ماهه 30 کودک سن مدرسه مبتلا به بیماری مزمن گوارشی و روماتیسمی بستری در بیمارستان و مادران آنان به عنوان گروه کنترل (دریافت کننده مراقبت روتین) وارد مطالعه شدند. نمونه‌گیری در دو مقطع زمانی 3 ماهه صورت گرفت. در مدت زمان پژوهش تمامی نمونه-هایی که معیارهای ورود به مطالعه را داشتند، وارد مطالعه گردیدند. پس از اتمام نمونه‌گیری مرحله کنترل (تعداد نمونه: 30 نفر)، مشارکت مدیریت شده پرستار- والد در بخش به اجرا گذاشته شد. پس از گذشت دو هفته از شروع اجرای مدل، 25 کودک بستری و مادران آنها به عنوان گروه آزمون وارد مطالعه گردیدند. رضایت مادران هر دو گروه نیز با استفاده از پرسشنامه رضایت از مراقبت تدوین شده توسط پژوهشگر در هنگام ترخیص مورد ارزشیابی قرار گرفت. یافته‌ها: یافته‌های پژوهش نشان داد که میانگین رضایت کلی مادران از مراقبت پرستاری در گروه آزمون (8/10±24/80) به طور معنی داری از گروه کنترل (8 ±7/20) بیشتر است (001/0>P). همچنین میانگین رضایت مادران در پنج حیطه اطلاع رسانی، ارتباطات، مهارتهای بالینی، عاطفی و مشارکت خانواده به تفکیک در گروه آزمون بطور معنی داری بیشتر از گروه کنترل است (001/0>P). نتیجه گیری: یافته های نهایی این پژوهش حاکی از آن است که مشارکت مدیریت شده پرستار- والد می-تواند جهت افزایش رضایت مادران از مراقبت مورد استفاده قرار گیرد

Parental participation and mismanagement: a qualitative study of child care in Iran.

The purpose of this study was to explore parents' and nurses' experiences of parental participation in child care in hospitals in Iran. Using thematic analysis, the data were collected through interviewing 14 parents and 11 nurses from two pediatric hospitals. The results showed that four major themes emerged, including the necessity of a parent's presence, the unplanned and informal delegation of care to the parents (which itself had five subthemes: the parents as nurses, the delegation of care without sufficient and planned parental training, informal parent-to-parent support, the continuum of parents' willingness to participate, and the neglect of parents' needs), the inconsistency of care, and the parents as informal evaluators of care. Based on the study's findings, effective communication by nurses with parents is required. Nurses need to make an ongoing assessment of parents' wishes for involvement and negotiate care accordingly, with enough support and supervision to warrant quality of care

Effect of antibacterial/adhesive approaches on bonding durability of fiber posts cemented with self-etch resin cement

Longevity of post-retained restoration is highly depended on bonding stability of fiber post (FP) to root dentin. This study evaluated the effect of different antibacterial/adhesive approaches on bonding durability of FPs luted into root canal with a self-etch cement. Seventy-two human maxillary central incisor roots were divided into six groups after endodontic treatment, based on the antibacterial/adhesive treatments as follows: 1)ED primer II (ED, control); 2) Clearfil Protect Bond (PB); 3) 2% chlorhexidine (CH) pretreatment + ED primer II (CH+ED); 4) CH-incorporated into ED primer II (CH in ED); 5) CH pretreatment + Clearfil SE Bond (CH+SE); and 6)CH-incorporated into SE primer (CH in SE). The FPs were then cemented using PanaviaF2.0. After micro-slicing the bonded root dentin, a push-out bond strength (PBS) test was performed immediately or after two years of water storage. Data were analyzed using ANOVA and post hoc Tukey tests (?=0.05). The effects of antibacterial/adhesive approach, time and interaction between the main factors were significant (p=0.01). There was no significant difference between the immediate groups, except between the CH+ED group (the lowest PBS) and PB and CH in SE groups (the highest PBS) (p?0.03). After aging, the same difference was observed (p?0.02); the control group exhibited a significantly lower PBS compared to the other groups (p?0.01), except for CH+ED. Aging significantly decreased PBS of all the groups (p?0.01); the control group exhibited the highest reduction. CH incorporated into self-etch primers or in pretreatment step prior to two-step self-etch adhesive and antibacterial adhesive could improve bond stability of self-etch cemented fiber post. However, none of these was capable of inhibiting bond degradation over time

ENRICHMENT OF CASING SOIL WITH FE AND SOY-FLOUR UNDER Pseudomonas INOCULATION ON YIELD AND QUALITY OF BUTTON MUSHROOM

Effects of casing soil enrichment with soybean flour (SF) and iron (Fe) were explored on yield and quality of edible mushrooms inoculated with plant growth-promoting bacteria in a factorial experiment with four replications. Fe from Fe chelate source was applied at two levels of 0 (Fe0) and 500 mg L-1 (Fe500), SF at three levels of 0% (SF0), 1.5% (SF1.5), and 3% (SF3) of compost dry weight, and bacteria inoculation at two levels (non-inoculation and inoculation of mycelia with P. putida). The maximum fresh yield (20.3 kg m-2), mushroom number (1041), biological efficiency (95.0%), vitamin C (3.74 mg 100 g-1 FW), and yield of protein (6.48 kg m-2) were obtained from SF1.5 + P. putida. But, the maximum tryptophan (1.37 mg g-1 DW), methionine (2.29 mg g-1 DW), and antioxidant capacity (4.25 mg mL-1) were related to SF3 inoculated with P. putida. Furthermore, the maximum carbohydrate (5.64%) was related to Fe500 + SF3. Based on the results, casing soil enrichment with Fe did not have a significant influence on quantitative and qualitative traits of mushrooms, but SF application at the rate of 1.5%, especially when accompanied by P. putida, played a more essential role. Thus, it is recommended to use 1.5% SF along with P. putida to enhance the yield and qualitative traits of edible mushrooms

Peak bone mass, which can be defined as the amount of bone tissue present at the end of the skeletal maturation, and also it is an important determinant of osteoporotic fracture risk. The peak bone mass of a given part of the skeleton is directly dependent upon both its genetics and environmental factors. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the pattern of peak bone mass in different countries across the globe. The present article explains the protocol for conducting such a research

A qualitative study on physical health threatening factors of Iranian seafarers working on ocean going tankers

Background: Seafaring is a highly physically demanding profession in a risky environment due to exposure to unique job health related risk factors. The purpose of the study is to describe physical health threatening factors of Iranian seafarers working on tankers. Materials and methods: A qualitative content analysis with inductive approach was performed on 17 Iranian male seafarers in 2016. Subjects were selected by purposive sampling, which continued until data saturation. Data were gathered using semi-structural questionnaire via in-depth-interviews. All interviews were transformed into computer files. Analysis was done based on conventional content analysis approach. Results: Mean job history and age of the participants was 11.9 ± 7.2 and 35.8 ± 9.3 years, respectively. Two main themes emerged during analysis of data and categories were created. The themes are (1) physical health threatening factors at the ship; (2) high risk ranks at the ship. Conclusions: The need for addressing nutrition at sea was acknowledged by seafarers. Also, it seems that revision of some regulations regarding seafarers’ medical examination, oral health and heart diseases is necessary
