RESUMEN

Objective: This study assessed the effects of Aloe vera supplementation on serum inflammatory factors, blood sugar and lipid profiles in hemodialysis patients. Materials and Methods: Totally, 50 hemodialysis patients were allocated randomly to either Aloe vera or placebo groups. The Aloe vera group received 2 Aloe vera capsules daily for 8 weeks (500 mg/day). Serum C-reactive protein (hs- CRP), Fasting blood glucose (FBS), and lipid profiles levels were evaluated at the baseline and the end of the eighth week. Results: Aloe vera supplementation for 8 weeks was associated with a significant reduction of serum hs- CRP (p=0.004), total cholesterol (p=0.01), low density lipoprotein (LDL) (p=0.02) leves and increased high density lipoprotein (HDL) (p=0.002) concentration in the hemodialysis patients. Conclusion: Aloe vera supplementation is beneficial in improvement of cardiovascular risk factors in hemodialysis patients.

RESUMEN

AIM: This study aimed to assess the effects of telenursing on patients' activities of daily living and instrumental activities of daily living (ADLs and IADLs) following a myocardial infarction (MI). METHODS: This randomized, parallel-group, controlled trial was conducted on 95 patients post-MI from 2018 to 2019. Patients were randomly assigned to the intervention (telenursing) and control groups using permuted block randomization. Through telephone calls, telenursing was performed twice a week during the first six consecutive weeks, then once a week until week 12. ADL and IADL questionnaires were completed by both groups before intervention and 12 weeks later. The CONSORT 2010 checklist was used to report the study protocol. RESULTS: The mean age of patients was 56.8 ± 11.07 and 54.2 ± 9.8 years in the telenursing and control group, respectively. The mean ADL and IADL scores in the telenursing group were substantially greater than in the control group [4.57 (3.18, 5.97); P < 0.001 and 4.40 (3.06, 5.75); P < 0.001, respectively]. The odds of a higher degree of independence (no disabilities vs. mild disabilities and disability as well as no disabilities and mild disabilities vs. disability) regarding ADLs and IADLs were significantly greater in the telenursing group as compared with the control group (P < 0.001 and P < 0.001, respectively). CONCLUSIONS: Our findings suggest that the use of telenursing intervention may increase patients' ADLs and IADLs after an MI and may enhance their independence.

RESUMEN

Many previous studies have investigated BTEX concentrations in urban areas; however, the available evidence on the association of different land-use types and BTEX concentrations is still scarce. In this study, the BTEX concentrations were measured and compared in different land-use types and traffic volumes of Mashhad metropolis, Iran. Sampling was conducted in summer and winter of 2018 based on NIOSH 1501 method in six land-use types, including Residential, Commercial/official, Industrial, Greenspace, Transportation, and Tourism. The spatial autocorrelation model was used to investigate the emission pattern. The Monte Carlo simulation technique and sensitivity analysis were used to assess the health risk of exposure to BTEX compounds. The median [interquartile range (IQR)] of benzene, toluene, ethylbenzene m-xylene, o-xylene and total BTEX concentrations based on overall mean were 4 (2.23), 8.37 (4.48), 1.2 (1.46), 0.89 (2.59), 0.8 (1.73) and 17.7 (8.19) µg/m3, respectively. Benzene and toluene had clustered emission patterns (z-score > 1.96). Exposure to benzene in the study area had a carcinogenic risk for inhabitants. The concentration of BTEX compounds was significantly different based on land-use type. The maximum and minimum concentrations of BTEX were observed in Transportation and Greenspace land uses, respectively. The BTEX concentrations in summer were significantly higher than in winter, and traffic had a significant effect on BTEX concentrations. Overall, our results supported a significant relationship between land-use type and BTEX concentrations in the urban area. Moreover, ambient benzene concentration had a carcinogenic risk potential for inhabitants of study area.

RESUMEN

BACKGROUND: Effective communication, including the complete and accurate transfer of information and the prevention of misrepresentation and misinterpretation of patient-centered data during handoff, can enhance the quality of patient care and safety. PURPOSE: This study was aimed at evaluating the impact of bedside handoff using the Situation, Background, Assessment, Recommendation (SBAR) technique, on the quality of nursing care. METHODS: The Quality Patient Care Scale (QUALPACS) was completed by the patient while nurses performed a verbal bedside shift handoff and after receiving education on the purpose and proper use of the SBAR communication tool. RESULTS: The mean age of subjects was 51.29 ± 8.02 years. We found a significant increase in the mean score of QUALPACS dimensions, namely psychosocial (P < .001), physical (P < .001), and communication (P < .001) after SBAR implementation. CONCLUSIONS: Findings suggest that using the SBAR handoff technique increases the quality of nursing care in all QUALPACS dimensions.

RESUMEN

OBJECTIVES: We sought to determine the effect of topical application of Nigella sativa (black seed) oil, on the primary dysmenorrhea intensity. METHODS: We conducted a randomized, double-blind clinical trial on 124 female students, 18-22 years old, living in the dormitories of Sabzevar Universities. After a primary assessment, participants were randomly divided into two groups. The first group rubbed two drops of N. sativa oil, and the second group rubbed liquid olive oil, as the placebo. Massage was performed on the fontanel lobe 3, at night, three days before menstruation, for eight consecutive days (about five days after menses). This procedure was repeated for three menstrual cycles. After three cycles, pain severity was measured by the visual analog scale. Data analysis was carried out using the Mann-Whitney U test and analysis of covariance (ANCOVA). RESULTS: This study was conducted on 124 female students. The mean age of students, mean age of first menarche, body mass index, and pain severity were not significantly different in the two groups (p > 0.050). No adverse effects were observed during the study. The results of ANCOVA showed that pain intensity in N. sativa oil group was significantly decreased compared to that of the placebo group (0.6 score; p < 0.050). CONCLUSIONS: N. sativa could be a promising, safe, and easily available analgesic supplement in women suffering from primary dysmenorrhea.

RESUMEN

BACKGROUND: The average age of using illicit drugs for the first time in adolescents has decreased in Iran over the past years. Studies show that family and environment play a notable role in keeping adolescents away from substances. AIMS: The present study is an attempt to develop and validate a model-based questionnaire to measure parental factors related to substance use prevention in adolescents. METHODS: This methodological study was carried out on 336 parents of high school students in Sabzevar- Iran, in 2018. The first draft of the questionnaire, including 136 items, was developed based on the constructs of the Health Promotion Model (HPM) using similar questionnaires, literature review, and interviewing 9 qualified experts. The validity of the questionnaire was measured through face validity (qualitative and quantitative), content validity (qualitative and quantitative), and construct validity (confirmatory factor analysis). The reliability of the questionnaire was measured by internal consistency and test-retest reliability. SPSS ver. 16 and LISREL ver. 8.2 software was used for statistical analysis. RESULTS: Throughout the validation process, 35 items were omitted, and the final version of the questionnaire consisting of 101 items was developed. The overall content validity ratio was 0.81, which indicates the proper and understandable content of the items. The overall content validity index was 0.96, which indicates excellent expert validity. The Cronbach's alpha coefficient of the questionnaire was 0.85 (constructs range= 0.73-0.96), and the intraclass correlation coefficient of the questionnaire was 0.78 (constructs range= 0.46-0.91), which indicates that the questionnaire has good internal consistency and test-retest reliability. Further, the confirmatory factor analysis yielded an appropriate fit for the model (RMSEA= 0.069, χ2/df= 2.77, GFI= 0.60, AGFI= 0.83, CFI= 0.83, NNFI= 0.83). CONCLUSION: The validity and reliability of the HPM-based questionnaire were supported. Therefore, the questionnaire can be used by health educators and health policymakers in empowerment programs for parents to improve their behavioral skills concerning the prevention of substance use in their adolescents.

RESUMEN

BACKGROUND AND PURPOSE: New pressor protein (NPP) is a human plasma enzyme, which is structurally related to the beta-fragment of activated factor XII. The present study aimed to compare the effects of angiotensin converting enzyme inhibitors (captopril) and angiotensin type 1 receptor blocker (losartan) on the hypertension induced by NPP injection in normal (sham-2NX) and bilaterally nephrectomized rats (2NX). EXPERIMENTAL APPROACH: In total, 60 male Wistar rats were sham operated or bilaterally nephrectomized under anesthesia. After 24 h of anesthesia with Inactin® (100 mg/kg), their systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were measured before and after the intravenous administration of captopril, losartan, and NPP. FINDINGS / RESULTS: In the sham-2NX group, after NPP injection, changes were observed in SBP (145.99 ± 3.6 mmHg), DBP (93.9 ± 3.87 mmHg), and HR (400.29 ± 12.78 bpm). In the captopril group, SBP and DBP had no significant changes, while HR increased significantly (P = 0.001). In the losartan group, SBP and DBP decreased (P = 0.001 and P = 0.000, respectively), while HR had no significant changes. In the 2NX group, after NPP injection, changes were denoted in SBP (127.89 ± 9.03 mmHg), DBP (65.86 ± 5.69 mmHg), and HR (333.35 ± 11.47 bpm). In addition, captopril injection increased DBP (P = 0.016) and HR (P = 0.036) in response to NPP injection, while losartan injection had no significant effects in this regard. CONCLUSION AND IMPLICATIONS: It could be concluded that losartan could improve hypertension in normal rats, while captopril deteriorated hypertension in bilaterally nephrectomized rats in this hypertension model.

RESUMEN

This study aimed to evaluate the effects of Nigella sativa oil on serum level of systemic inflammation, oxidative stress, fasting blood glucose (FBG), and lipid profile in patients with type 2 diabetes mellitus (T2DM). This double-blind randomized clinical trial study was based on 50 patients with T2DM. Patients were allocated randomly to either N. sativa oil or placebo groups. The intervention group received 1,000 mg N. sativa oil as two capsules, daily for 8 weeks, whereas the placebo group received a corresponding placebo. At baseline and the end of the study, 5 ml blood was collected from each patient after 14-hour fasting for measuring serum C-reactive protein (hs-CRP), malondialdehyde (MDA), FBS, and lipid profile. Analyses covariance was performed to compare investigated parameters between two groups, controlled for relevant covariates. Using N. sativa supplement was significantly associated with decrease in FBS (p < .001), triglyceride (p < .001), total cholesterol (p < .001), low-density lipoprotein cholesterol (p < .001), serum hs-CRP, MDA (p < .001) and increase in serum level of high-density lipoprotein cholesterol (p < .001) in intervention group compared with placebo group. Nigella sativa oil supplement has cardiovascular protective effects in patients with T2DM, by improving the lipid profile and glycemia, by reducing the C-reactive protein level and the lipid peroxidation.

RESUMEN

INTRODUCTION: Assessment of early clinical warning signs and appropriate response can prevent serious adverse events in hospitalized patients. The Modified Early Warning Score (MEWS) is an applicable early warning sign system that can be used to predict serious adverse events. This study aimed to evaluate the predictive capacity of the MEWS to identify patients in an Iranian hospital who are at risk of developing serious adverse events. METHODS: In this prognostic study, 381 adult patients from the emergency department who were admitted to an inpatient hospital unit of an Iranian hospital from May 2018 to October 2018 were included. The MEWS tool was completed for each patient at the time of admission and then daily for a period of up to 30 continuous days after admission or until the development of a serious adverse event. Receiver operating characteristic, specificity, sensitivity, positive predictive values, and negative predictive values were calculated. RESULTS: In this study, a MEWS of ≥3 on admission was associated with an increased likelihood of developing serious adverse events within 30 days of admission with the area under the curve of 0.82 (95% confidence interval [CI]: 0.77-0.85), sensitivity of 82.81% (95% CI: 71.3-91.1), specificity of 75.39% (95% CI: 70.3-80), positive predictive value of 40.5% (95% CI: 35.2-45.9), and negative predictive value of 95.6% (95% CI: 92.7-97.4). DISCUSSION: A MEWS ≥3 on admission can predict the occurrence of serious averse events in patients admitted to an Iranian hospital for 30 continuous days.

RESUMEN

OBJECTIVES: Health education programs are one of the most important strategies for controlling cutaneous leishmaniasis (CL) in endemic areas such as Neshabur city. This study aimed to develop and evaluate a comprehensive health education program to improve preventive behaviors for CL. METHODS: This was an interventional study conducted on 136 high school students in Neishabur city. Data collection instruments included a demographic questionnaire and a researcher-made questionnaire based on the "Health Belief Model" and "Beliefs, Attitudes, Subjective Norms and Enabling Factors Model" constructs. The control and intervention groups completed the questionnaires before and 2 months after the intervention. The intervention was conducted in 6, 1-hour educational sessions for the intervention group students and 2, 1-hour sessions for school administrators, teachers, and students' parents. RESULTS: There was no significant difference between the 2 groups in the pre-intervention phase. However, in the post-intervention phase, there were significant differences between the 2 groups for mean scores of knowledge, perceived susceptibility, perceived severity, perceived benefits, cues to action, self-efficacy, attitude, subjective norms, behavioral intention, enabling factors, and behavior associated with CL. CONCLUSION: Health education program based on the "Health Belief Model" and the "Beliefs, Attitudes, Subjective Norms and Enabling Factors Model" model constructs may be a comprehensive and effective educational program to improve preventive behaviors against CL in students.

RESUMEN

INTRODUCTION: Low quality of sleep is a common problem among hemodialysis patients. This study was conducted to evaluate the effect of a cold dialysis solution on the quality of sleep in patients undergoing hemodialysis. METHODOLOGY: This double-blind clinical trial was performed on 26 hemodialysis patients with chronic renal failure and sleep disorders in the dialysis center of Sabzevar, Iran, in 2016-2017. Of the 26 patients, 13 each were allocated to the intervention and control groups. The patients in both groups received 4 weeks of hemodialysis (3 sessions per week) using a standard solution with a temperature of 37°C. In the next stage, the control group continued to receive the standard-temperature dialysis, while the intervention group received dialysis using a solution with a temperature of 35.5°C for 4 weeks (3 sessions per week). The Pittsburgh Sleep Quality Index was used to assess and compare the quality of sleep before and after the intervention in the two groups. Data were analyzed using R 1.2.3 software, at 95% confidence level. RESULTS: Although the mean scores of sleep quality were not significantly different between the intervention (9.53 ± 3.12) and control (11.23 ± 3.37) groups at baseline, postintervention, significant differences were observed (intervention group: 4.7 ± 4.55; control group: 10.61 ± 2.69; P < 0.001). CONCLUSION: This study showed that dialysis with cold solution is a simple, cost-effective, and nonpharmacological method that can be used to improve sleep quality in patients undergoing hemodialysis.

RESUMEN

Background: PTEN protein is one of the most important tumour suppressor factors which is detectable by immunohistochemistry. The goal of the present study was to investigate the prognostic role of PTEN gene expression in breast cancer patients. Materials and Methods: This descriptive-analytical study was conducted on 100 breast cancer patients referred to Sabzevar hospitals in the north-east of Iran between 2010 and 2011, who were followed up to 2015. PTEN gene expression in tissue samples was determined using specific monoclonal antibodies and data were analyzed using Chi-square test and Fisher's exact test. Patient survival was analyzed after 4 years of follow-up using the Cox regression model. Results: PTEN gene expression was evident in 70 of 100 cnacer samples but was found at high levels in all non-cancer samples. There was an inverse significant relationship between PTEN gene expression and tumour stage or tumour grade (p<0.001). The expression of PTEN in invasive ductal tumours was lower than in non-invasive tumours. There was also an inverse significant relationship between the hazard of death and PTEN gene expression (p<0.001). In addition, there was an inverse significant relationship between tumour stage and hazard of death (p<0.001). Conclusion: These findings indicate that lack of PTEN gene expression can be a sign of a worse prognosis and poor survival in breast cancer cases.

RESUMEN

PTEN protein is an important tumour suppressor factor detectable by immunohistochemistry. The goal of the present study was to investigate the prognostic role of PTEN gene expression focusing on length of survival in breast cancer patients. This descriptive-analytical study was conducted on 100 breast cancer cases referred to Sabzevar hospitals in the north east of Iran between 2010 and 2011, followed up to 2015. The PTEN gene expression of tumour tissue samples was determined using specific monoclonal antibodies. The data were analyzed using Chi-square test and Fisher's exact test. Patient length of survival was analyzed after 4 years of follow-up using the Cox regression model. The PTEN gene was expressed in 70 of 100 samples, while being found at a high level in all noncancerous samples. There was an inverse significant relationship between expression of PTEN and tumour stage and grade (p<0.001). In addition, expression of PTEN in invasive ductal tumours was less than in non-invasive tumours. There was also an inverse significant relationship between the likelihood of death and PTEN gene expression (p<0.01). These findings indicate that lack of PTEN gene expression can be sign for a poor prognosis in breast cancer.

RESUMEN

BACKGROUND: Limited evidence supports Nigella sativa's role as an effective complementary and alternative medicine and the anti-inflammatory effects of Nigella sativa on patients with allergic rhinitis. OBJECTIVE: The aim of this study was to investigate the effect of topical application of Nigella sativa oil and oral acetaminophen on pain in the elderly with knee osteoarthritis residing in a parents' home in Sabzevar. METHODS: This study is done as a crossover clinical trial. After obtaining written consent of elderly patients with osteoarthritis of the knee, they were randomly divided into two groups. In step 1, in group 1, 1 cc of Nigella sativa oil was applied on the knee joint every 8 hours for 3 weeks; for the second group, every 8 hours for 3 weeks, patients were given 1 tablet of 325 mg acetaminophen. After a period of 1 month without medication to wash out each group, in step 2, each treatment group received the drug interaction in the same way as above. Pain was determined using a visual scale (VAS) before and after the first and second stages. Treatment response was defined as a decrease in pain scores over 1.5. Data analysis was performed with an R software mixed model. RESULTS: This study was done on 40 elderly patients: 18 (45%) men and 22 (55%) women. Their mean year and weight were 75.66±8.9 years and 69.67±14.33 kg, respectively. Study results showed that topical application of Nigella sativa oil and oral acetaminophen reduced pain in elderly with knee osteoarthritis; after using Nigella sativa oil, the reduction of pain was higher (p=0.01). CONCLUSION: The results of this study showed that topical application of Nigella sativa oil was effective in reducing pain in patients with knee osteoarthritis; therefore, it is recommended as a safe supplement for these elderly. TRIAL REGISTRATION: The trial was registered at TCTR (http://www.clinicaltrials.in.th/) with the ID: TCTR20160125003. FUNDING: This study was approved and supported by the Sabzevar University of Medical Sciences.

RESUMEN

PURPOSE: Ileus is a common event following cesarean section. Early post-cesarean recovery is very important not only for the mother but also for the baby who is dependent on breastfeeding. This article aims to demonstrate the efficacy of metoclopramide for the prevention of ileus after cesarean. METHODS: In this randomized controlled trial, 696 women scheduled for cesarean were randomized in two groups. Three hundred fifty-three persons settled in control group and 343 were assigned in intervention group who received an injection of 10-mg intramuscular metoclopramide prior to operation. After cesarean, the participants recorded the first flatus, defecation, feeling of hunger, feeding and ambulation in a questionnaire, and also their sense of bloating in a visual analog scale under supervision of a research assistant. The data was analyzed by SPSS 17, t test, and chi-square, while p < 0.05 was considered significant. RESULTS: The interval between cesarean and the first flatus (p < 0.0001), defecation (p < 0.0001), feeling of hunger (p < 0.0001), feeding (p = 0.007), and ambulation (p < 0.0001) were significantly shorter in the metoclopramide group. In addition, polytomous logistic regression analysis showed the metoclopramide group had less bloating with significant difference (OR = 2.83 and CI 1.91-4.21). CONCLUSIONS: Our study proved the functionality of metoclopramide in preventing ileus. As this drug is safe, tolerable, harmless, inexpensive and available, and also no definite method has been developed to prevent ileus after cesarean; yet, metoclopramide could be considered as a suitable option. Certainly with regard to some limitations in our study, further comprehensive studies are still required to ensure validity of the obtained results.

RESUMEN

INTRODUCTION: The neonatal mortality rate (NMR) is an essential index in the assessment of community health. With the rapid advancement of neonatal care, the causes of death in this group and the overall mortality rate have changed. For these reasons, the aim of this study was to determine the current NMR and its causes in Sabzevar City's Neonatal Intensive Care Unit (NICU). METHODS: This cross-sectional study was conducted in the NICU at Sabzevar Hospital from 2006 through 2013. Based on previous studies, the sample size was determined to be 365 neonates who were admitted to the NICU and died before they were discharged. The study tool was a researcher-developed checklist related to deceased neonates in the NICU. The checklist was confirmed based on the validity of its content and its inter-rater reliability. We used chi-squared, the Mann-Whitney U test, and the Spearman correlation to analyze the data. RESULTS: The NMR in Sabzevar's NICU was 6.44 per 1000 during the seven-year period; this rate included the following cases per 1000 live births: very early mortality (2.16), early mortality (3.33), and late mortality (0.96). Among 58,270 live births, 3,667 of the neonates were admitted to the NICU during the seven-year period, which was equivalent to 62.93 admissions per 1000 live births. Of the 3,667 neonates admitted to the NICU, 375 (10.23%) died before they were discharged. The most recurrent diagnoses were respiratory distress syndrome (46%), followed by sepsis (12%). The one-sample chi-squared test as a goodness-of-fit test (95% CI) showed that the mortality rates were significantly different based on gender (p = 0.004), birth weight (p < 0.001), gestational age (p < 0.001), different causes of death (p < 0.001), and different years of death (2006-2013) (p < 0.001). There also was a significant difference between the duration of survival (very early mortality, early mortality, and late mortality) (p < 0.001). CONCLUSION: Neonatal mortality in the present study was comparable with that reported in similar studies in Iran and in other countries. The strong association between the mortality rate in the NICU with premature birth and low birth weight indicates the necessity of prenatal care aimed at preventing pre-term labor. Comprehensive programs from antenatal care and care at and after birth are recommended, including the investigation of the risks for neonatal death and offering preventive strategies.
