Comparing two instructional methods of role playing and lecture on primigravida females, decision about type of delivery.

INTRODUCTION: Each mother has the legal right to decide about her delivery, but this decision should be made based on scientific knowledge. Instructions during pregnancy help to choose the proper type of delivery. This study conducted aimed to compare two instructional methods of role playing and lecture on primigravida decision about type of delivery. SUBJECTS AND METHODS: In this single-blind clinical trial 67 primigravida, 34-36 week were selected using multi-stage sampling and assigned into two groups randomly. Decision-making (before, 2-week after, and at admission in maternity department) was tested by a questionnaire. In role-playing group, advantages and disadvantages of two type delivery were presented by role-playing in 90-min by three scenarios. In lecture group, it was also presented in a 90-min lecture. Data were analyzed by mean difference test, Fisher test, independent and paired t-test. RESULTS: Two groups showed a significant difference in terms of decision at admission to maternity department (P = 0.000). 75% of lecture group and 100% of role-playing group selected normal delivery. Postintervention knowledge score in lecture group was 18 ± 5.3 and in role-playing group 17.1 ± 4.0. Percent of change in knowledge scores in two groups was significant (P = 0.001). Participants' attitude, before and after the intervention, in both groups was significant (P < 0.05). Mean difference of pre- and post-test in relation to two groups' knowledge and attitude scores was not significant (P > 0.05). CONCLUSION: In this research, lecture was more effective in raising knowledge level, and role playing was more effective in raising decision to vaginal delivery and reducing elective caesarean section. It is therefore suggested to use both teaching methods altogether for pregnant women to decrease the rate of unnecessary cesarean.

The Effect of Acupressure on Sleep Quality in Menopausal Women: A Randomized Control Trial.

BACKGROUND: One of the common problems in menopausal women is sleep disorder. Traditional Chinese acupressure is a noninvasive and safe technique. Menopausal women can easily learn the technique and a self-care method to manage their sleep disorder. This study was carried out to evaluate the effectiveness of acupressure on sleep quality of postmenopausal women in Mashhad during 2009. METHODS: This double blind, randomized clinical trial was performed on 120 qualified menopausal women at the age of 41-65 years. Their sleep quality was measured according to the Pittsburgh Sleep Quality Index (PSQI). Participants were randomly assigned to an acupressure group (n=37), a sham acupressure group (n=36) and a control group (n=32) by two time randomized method (systematic and simple randomized). These interventions were carried out for four consecutive weeks. The participants in the acupressure and sham acupressure groups learned to carry out the acupressure technique as a self-care at home with simultaneous massage techniques that were to be performed 2 hours before sleep, whereas only conversation was used in the control group. The data were analyzed by the SPSS software version 17. RESULTS: The results indicated significant differences in total PSQI scores among the three groups (P<0.001). Tukey's test revealed that there were significant differences between the acupressure group and the control group (P<0.001), the acupressure group and sham acupressure group (P<0.001), and the sham acupressure and the control group (P<0.001). CONCLUSION: Acupressure can be used as a complementary treatment to relieve sleep disorders in menopausal women; and is offered as an efficient method to manage sleep quality.

Diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women.

BACKGROUND: Dystocia is one of the important causes of maternal morbidity and mortality in low-income countries. This study was aimed to determine the diagnostic accuracy of maternal anthropometric measurements as predictors for dystocia in nulliparous women. MATERIALS AND METHODS: This prospective cohort study was conducted on 447 nulliparous women who referred to Omolbanin hospital. Several maternal anthropometric measurements such as height, transverse and vertical diameters of Michaelis sacral rhomboid area, foot length, head circumference, vertebral and lower limb length, symphysio-fundal height, and abdominal girth were taken in cervical dilatation ≤ 5 cm. Labor progression was controlled by a researcher blind to these measurements. After delivery, the accuracy of individual and combined measurements in prediction of dystocia was analyzed. Dystocia was defined as cesarean section and vacuum or forceps delivery for abnormal progress of labor (cervical dilatation less than 1 cm/h in the active phase for 2 h, and during the second stage, beyond 2 h or fetal head descend less than 1 cm/h). RESULTS: Among the different anthropometric measurements, transverse diameter of the Michaelis sacral rhomboid area ≤9.6 cm, maternal height ≤ 155 cm, height to symphysio-fundal height ratio ≤4.7, lower limb length ≤78 cm, and head circumference to height ratio ≥ 35.05 with accuracy of 81.2%, 68.2%, 65.5%, 63.3%, and 61.5%, respectively, were better predictors. The best predictor was obtained by combination of maternal height ≤155 cm or the transverse diameter of the Michaelis sacral rhomboid area ≤9.6 cm and Johnson's formula estimated fetal weight ≥3255 g, with an accuracy of 90.5%, sensitivity of 70%, and specificity of 93.7%. CONCLUSIONS: Combination of other anthropometric measurements and estimated fetal weight with maternal height in comparison to maternal height alone leads to a better predictor for dystocia.

Assessment of ABCD² scale in patients with transient ischaemic attack or stroke.

BACKGROUND AND PURPOSE: Stroke risk prediction scores have been designed to stratify risk of recurrent cerebrovascular events in patients with transient ischaemic attack (TIA) or minor ischaemic stroke (MIS). MATERIAL AND METHODS: Consecutive patients with TIA or MIS referring to Ghaem Hospital, Mashhad presenting within 24 hours from the onset of symptoms were recruited to the prospective cohort study between 2010 and 2011. MIS was defined as an ischaemic stroke with National Institutes of Health Stroke Scale (NIHSS) score < 4. The end-point of the study was a new ischaemic cerebrovascular event or vascular death at 90 days and, additionally, at 3 days after the index TIA or MIS. The decision to admit and of method of treatment in each case was left to the discretion of the stroke neurologist. The predictive accuracy of the ABCD2 scoring system for recurrent stroke or TIA was quantified by the area under the curve (AUC), using the c-statistics. RESULTS: The study included 393 patients with TIA (238 males, 155 females) and 118 patients with MIS (77 males, 41 females). Among 511 patients with minor ischaemic events, 117 strokes (23.2%), 99 TIAs (19.6%), and 11 vascular deaths (2.2%) occurred within 3 months after the index event. The ABCD2 score had a weak predictive value for 3-month and 3-day recurrent stroke in patients with TIA (AUC = 0.599 and 0.591, respectively), but a high predictive value for 3-month and 3-day recurrent stroke in patients with MIS (AUC = 0.727 and 0.728, respectively). CONCLUSION: The ABCD2 score is highly predictive for short-term recurrent stroke in patients with MIS but not in patients with TIA, although it was originally designed for patients with TIA.

Development and validation of the Asian Migraine Criteria (AMC).

Physicians often do not use the International Classification of Headache Disorders (ICHD-II) for diagnosis of migraine in their routine clinical practice. The diagnosis of headache subtypes in 453 patients was made by headache experts according to the ICHD-II and the likelihood ratios (LR) of clinical characteristics of migraine were calculated in Part I of the study. Asian headache specialists designed the Asian Migraine Criteria (AMC) based on these LR and their experience. In Part II of the study, another group of 500 patients with headache were evaluated by a family physician, based on the AMC. Thereafter the headache experts, who were blinded to the diagnosis of these patients based on the AMC, re-evaluated them according to the ICHD-II. The AMC consists of seven items: (i) unilateral location; (ii) throbbing quality; (iii) nausea and/or vomiting; (iv) photophobia and/or sonophobia; (v) osmophobia; (vi) family history of migraine; and (vii) aura. In the AMC the presence of at least three items in adults and at least two items in children is necessary for the detection of definite migraine. The AMC had a sensitivity 99.3%, specificity 84.5%, positive predictive value (PPV) 96.9%, negative predictive value (NPV) 96.1% and validity of 96.8% for diagnosis of adult migraine compared to the ICHD-II as the gold standard. The AMC had a sensitivity 93.5%, specificity 46.8%, PPV 69.9%, NPV 86.6% and a validity of 73.4% for detection of childhood migraine against the ICHD-II. The AMC was shown to be a highly valid and reliable tool for screening of adult migraine by non-neurologists. AMC was shown to be moderately valid for detection of pediatric migraine.

Comparative interrater reliability of Asian Stroke Disability Scale, modified Rankin Scale and Barthel Index in patients with brain infarction.

BACKGROUND: This study tried to develop an Asian Stroke Disability Scale (ASDS) and compared its interrater reliability with modified Rankin Scale (mRS) and Barthel Index (BI). METHODS: Three items including self-care, mobility, and daily activities were selected as variables for development of the ASDS. The variables were provisionally graded on a 2- to 4-point scale based on the importance of each item. Each of the variables was categorized into 3 categories. Afterward, 125 rater-patient assessments for each scale (mRS, BI, and ASDS) were performed on 25 stroke patients by 5 raters. For categorization of functional impairment as minor or major, the scores of mRS, BI and ASDS were categorized as ≤ 2 and > 2, < 90 and ≥ 90, and < 3 and ≥ 3, respectively.125 rater-patient assessments for each of the mRS, BI, and ASDS were performed on 25 stroke patients by five raters. RESULTS: The quantitative variability of BI, mRS, and ASDS scores was not significant (P = 0.379; P = 0.780; and P = 0.835, respectively). Interrater variability of mRS, BI, and ASDS scores based on qualitative categorization was not significant (P = 1.000; P = 0.978; and P = 0.901, respectively). Paired interrater variability of mRS, BI, and ASDS scores based on qualitative categorization was not significant (P > 0.05). CONCLUSION: The ASDS is easy to use, requires less than 1 minute to complete and is as valid as mRS and BI in assessment of functional impairment of patients with stroke.

The ABCD(2) Score is Highly Predictive of Stroke in Minor Ischemic Stroke Patients.

Stroke risk prediction scores have been designed to stratify risk of recurrent cerebrovascular events in transient ischemic attack (TIA) and minor ischemic stroke (MIS) patients. Consecutive TIA or MIS patients referred to Ghaem Hospital, Mashhad were enrolled in a prospective cohort study during 2010-2011. Only TIA or MIS patients presenting within 24 h from the onset of symptoms were recruited. MIS was considered as ischemic stroke with NIHSS <4. The end point of the study was a new ischemic cerebrovascular event or vascular death at 90 days and additionally at 3 days. The decision to admit and treatment in each case was left to the discretion of the stroke neurologist. The predictive accuracy of the ABCD(2) scoring system for recurrent stroke or TIA was quantified by the area under the cure (AUC) using the c statistics. Three hundred ninety-three TIA patients (238 males, 155 females) and 118 MIS patients (77 males, 41 females) were enrolled in the study. One hundred seventeen strokes (23.2%), 99 TIA (19.6%), and 11 vascular death (2.2%) occurred within 3 months postevent in the whole of our 511 patients with minor ischemic events. The ABCD(2) score had a weak predictive value for 3 months and 3 days recurrent stroke in our TIA patients (AUC = 0.599, AUC = 0.591), but a high predictive value for 3 months and 3 days recurrent stroke in our MIS patients (AUC = 0.727, AUC = 0.728), respectively. The ABCD(2) score is highly predictive of short-term recurrent stroke in MIS patients but not TIA cases, despite its creation for TIA cohorts.

A comparison of face to face and video-based education on attitude related to diet and fluids: Adherence in hemodialysis patients.

INTRODUCTION: Adherence to diet and fluids is the cornerstone of patients undergoing hemodialysis. By informing hemodialysis patients we can help them have a proper diet and reduce mortality and complications of toxins. Face to face education is one of the most common methods of training in health care system. But advantages of video- based education are being simple and cost-effective, although this method is virtual. MATERIALS AND METHODS: Seventy-five hemodialysis patients were divided randomly into face to face and video-based education groups. A training manual was designed based on Orem's self-care model. Content of training manual was same in both the groups. In the face to face group, 2 educational sessions were accomplished during dialysis with a 1-week time interval. In the video-based education group, a produced film, separated to 2 episodes was presented during dialysis with a 1-week time interval. An Attitude questionnaire was completed as a pretest and at the end of weeks 2 and 4. SPSS software version 11.5 was used for analysis. RESULTS: Attitudes about fluid and diet adherence at the end of weeks 2 and 4 are not significantly different in face to face or video-based education groups. The patients' attitude had a significant difference in face to face group between the 3 study phases (pre-, 2, and 4 weeks postintervention). The same results were obtained in 3 phases of video-based education group. CONCLUSION: Our findings showed that video-based education could be as effective as face to face method. It is recommended that more investment be devoted to video-based education.
