RESUMEN
Background: Perforator flaps have recently been used in the field of plastic surgery. Skin defects can be reconstructed to reach functional and cosmetic goals. With the development of reconstructive approaches, utilizing stem cells is a hopeful approach to enhance wound healing and tissue recovery. In this study, we assessed the effect of bone marrow mesenchymal stem cells on the perforator flap's survival in rats. Methods: Perforator flaps (2.5 × 11 cm) were transplanted into rats and focused on the thoracodorsal, intercostal, and deep circumflex arteries, which were randomly divided into three groups: control, saline, and bone marrow mesenchymal stem cells (7 × 106 ml). Seven days after the surgery, tissue edema, inflammation, and discharge were observed and photographed. Histological analyses were performed to determine flap survival. Hematoxylin and eosin staining was performed to assess levels of microvascular density determined in skin flaps. Results: Rats in the bone marrow mesenchymal stem cells group exhibited higher average flap survival area, and higher microvascular density levels at the dynamical regions of the flaps compared with the other two groups. Subdermal injection of bone marrow mesenchymal stem cells significantly increased ischemic perforator flap survival due to stimulated neovascularization in rats. Conclusion: Our findings suggest the potential usefulness of bone marrow mesenchymal stem cells in preventing skin flap perforator tissue necrosis.
RESUMEN
BACKGROUND: Previous studies have examined relationship between cognitive function and lifestyle; however, the nature of this relationship is expected to vary in diverse cultural and low-income setting where lifestyle practices differ from those in high-income countries. AIM: This study aims to investigate the correlation between lifestyle factors and cognitive function among individuals aged 60 years and older in 2021. METHODS: This cross-sectional, Community-based study involved 300 older adults from comprehensive urban health centers in Khorramabad, Iran, selected through stratified cluster sampling. Data were collected using the demographic information questionnaire, Mini-Mental State Examination, and Lifestyle Questionnaire. Data management and analysis were performed using SPSS (version 22) and independent t-tests, Pearson's correlation coefficient, ANOVA, and multiple linear regression analysis were used. A p value < 0.05 was considered significant. RESULTS: The study included 156 males (52%) and 144 females (48%). Findings revealed a significant correlation between cognitive function and lifestyle (P < 0.001). Multiple linear regression analysis indicated that physical health, environmental health, exercise, accident prevention, and avoidance of medication exerted the most significant positive effect on cognitive function. Conversely, social health exhibited a notable negative influence on cognitive function. (P < 0.001). CONCLUSION: The results suggest that specific aspects of lifestyle, such as physical health, accident prevention, and avoidance of medication are associated with cognitive function in older adults. Consequently, lifestyle promotion programs may enhance cognitive function and improve the quality of life among older adults.

BACKGROUND: Dietary intake of phytochemicals has been associated with a reduced risk of chronic diseases, but research on their relationship with benign prostatic hyperplasia (BPH) is limited. This case-control study aimed to investigate the association between a Dietary Phytochemical Index (DPI) and BPH risk in a Middle-Eastern population. METHODS: The study recruited 112 BPH patients and 112 age-matched healthy controls (40-75 years) from Al-Zahra Hospital Clinic in Isfahan, Iran between 2021 and 2022. Dietary intake was assessed using a validated food-frequency questionnaire, and DPI was calculated as the ratio of energy intake from phytochemical-rich foods to total daily energy intake. Logistic regression analysis was performed, adjusting for potential confounders. RESULTS: In the crude model, participants in the highest DPI tertile had a 70% lower odds of BPH compared to those in the lowest tertile (OR:0.3, 95% CI 0.15-0.61, P-trend = 0.001). After adjusting for confounders, this inverse association remained significant (OR:0.23, 95% CI 0.15-0.63, P-trend = 0.001). Participants with higher DPI consumed more whole grains (p = 0.02), nuts (p < 0.001), legumes (p = 0.02), fruits (p < 0.001), vegetables (p < 0.001), olives and oilve products (p = 0.02), and tomato and its products (p < 0.001) in their diet compared to the lowest tertile. However, red meat (p = 0.03) and refined grains (p < 0.001) were consumed in higher amounts in the lowest tertile compared to the highest DPI tertile. CONCLUSIONS: This study demonstrates a protective association between DPI and BPH risk in the Middle-Eastern population. Encouraging higher intake of phytochemical-rich foods may help reduce the risk of BPH, highlighting the relevance of nutritional science in promoting prostate health.

OBJECTIVES: Measures to reduce nurses' fatigue are necessary to improve the patient's care and the nurse's health and well-being. This study investigated the effectiveness of aromatherapy with Pelargonium graveolens (P. graveolens) essential oil on fatigue and sleep quality of nurses working in intensive care units (ICU). METHODS: In this double-blind, randomized, controlled clinical trial, 84 nurses working in the ICU of Covid-19 patients were assigned to two groups of P. graveolens and placebo by the stratified block method. The intervention group inhaled one drop of pure P. graveolens. The placebo group inhaled one drop of pure sunflower oil in three consecutive shifts (morning or evening) and each shift twice for 20 min. Using the Visual Analog Fatigue Scale (VAS-F), fatigue was measured 30 min before the intervention, immediately, and 60 min later. Also, on the morning of the intervention days, sleep quality was assessed with the Verran and Snyder-Halpern (VSH) Sleep Scale. Data analysis was performed using SPSS, version 24. Independent t-tests, Mann-Whitney, Chi-square tests, and MANOVA, were used. RESULTS: The mean score of fatigue immediately and 60 min after aromatherapy in the P. graveolens group was lower than in the control group (P Ë 0.05). There was no significant difference between the mean sleep scores of nurses in the P. graveolens group before and after the intervention (P > 0.05). CONCLUSION: Inhalation aromatherapy with P. graveolens essential oil can reduce nurses' fatigue in the ICU. The findings of this study can make nurses interested in using aromatherapy as a self-care method.

BACKGROUND: In patients living with chronic obstructive pulmonary disease (COPD), cognitive impairment and reduced activities of daily living (ADLs) are associated with poor clinical outcomes. AIM: The aim of the present study was to determine the effect of rosemary hydroalcoholic extract on cognitive function and ADLs in patients with COPD. METHODS: A total of 77 COPD patients aged 40-80 years were assigned to two intervention and control groups by random stratified block method in the current tripleblind clinical trial. The intervention group received 500 mg rosemary capsules and the control group received oral capsules containing corn powder twice a day, one to two hours before breakfast and dinner, for two months. The Montreal Cognitive Assessment-Basic (MoCA-B), London Chest Activity of Daily Living scale (LCADL) and Lawton Instrumental Activities of Daily Living (IADL) were used to measure cognitive function and the measure of basic and instrumental daily life activities, before and after the intervention, respectively. RESULTS: The mean total score of cognitive function (P = 0.022) and the two subscales of abstraction (P = 0.003) and naming (P = 0.034) significantly increased after the intervention in the intervention group. There was no significant difference between the intervention and control groups in terms of changes in the mean scores of IADL and LCADL (P < 0.05). The final statistical model showed that the changes in the total mean score of cognitive function (P = 0.014) and IADL (P = 0.047) in intervention group patients are significantly higher than in the control group after adjusting the effect of obstructive sleep apnea (OSA). CONCLUSION: The rosemary hydroalcoholic extract can be effective in improving cognitive function and IADL in patients with COPD, but not LCADL.

RESUMEN
OBJECTIVE: This study was aimed to determine the relationship between job stress and work-related quality of life (WRQoL) among emergency medical technicians (EMTs) in Lorestan province, Western Iran. DESIGN: This was a cross-sectional study. METHODS: Totally 430 EMTs who had been engaged in their respective units for more than 6 months from all emergency facilities in Lorestan province were selected using single stage cluster sampling method. Data were collected from April to July 2019 using two standard questionnaires: job stress (Health and Safety Executive (HSE)) and WRQoL. The OR with 95% CI was used to declare the statistical association (p≤0.05). RESULTS: All participants were exclusively males, with a mean age of 32±6.87 years. The overall average score of job stress using the HSE scale was 2.69±0.43; while the overall quality of working life score was 2.48±1.01. The type of working shift was found to have a significant impact on the HSE-average score (F(3,417)=5.26, p=0.01); and on the WRQoL-average score (F(3,417)=6.89, p<0.01). CONCLUSION: Two-thirds of EMTs working in governmental hospitals had job stress and a low quality of work-related life. Additionally, work shift was statistically significant associated with EMTs' job stress and WRQoL.

Introduction: Family caregivers of patients with cancer face a care burden due to the responsibilities and problems of providing care to the patients. Applying appropriate strategies to reduce the burden is essential. Objective: The study aimed to determine the effect of education and telephone follow-up on family caregivers' burden on patients with cancer. Methods: In this quasi-experimental study, 69 family caregivers of patients with cancer referred to only one chemotherapy center of a hospital in Lorestan province in Iran were recruited by convenience sampling method. They were randomly assigned to intervention (n = 33) and control (n = 36) groups. For the intervention group, two face-to-face training sessions and six telephone counseling sessions were held related to the care of the patients and self-care. The control group received only routine care. The family caregiver burden was measured by Novak and Gast Caregiver Burden Inventory (1989) completed before, immediately, and 6 weeks after the study. Data were analyzed by SPSS21 using independent t-tests, paired t-tests, and repeated measures. Results: Both groups were homogeneous regarding demographic characteristics and the baseline care burden. The caregiver burden decreased significantly in the intervention group, so its score was 77.33 ± 8.49, 58.93 ± 8.03, and 52.78 ± 6.86 before the study, immediately after and 6 weeks later, respectively (p < .001). In the control group, there were no significant changes. Conclusion: Education and telephone counseling reduced the burden on family caregivers. Therefore, this type of support is beneficial for providing holistic care and preserving the health of family caregivers.
RESUMEN
BACKGROUND: In the absence of effective antiviral drugs or vaccines, early and accurate detection of SARS-CoV-2 infection is essential to the COVID-19 pandemic. This study developed and evaluated a novel rapid One-Step LAMP assay to directly detect the SARS-CoV-2 RNA from nasopharyngeal (NP) swab samples of patients with suspected SARS-CoV-2 infection living in deprived areas in comparison to One-Step Real-time PCR. METHODS: Two hundred fifty-four NP swab samples from patients suspected of COVID-19 infection living in deprived western areas of Iran were tested by TaqMan One-Step RT-qPCR and fast One-Step LAMP assays. Tenfold serial dilutions of SARS-CoV-2 RNA standard strain where the viral copy number in each dilution was previously determined using the qPCR and various templates were used to investigate the analytical sensitivity and specificity of the One-Step LAMP assay in triplicate. Also, the efficacy and reliability of the method compared to TaqMan One-Step RT-qPCR were evaluated using SARS-CoV-2 positive and negative clinical samples. RESULTS: The results of the One-Step RT-qPCR and One-Step LAMP tests were positive in 131 (51.6%) and 127 (50%) participants, respectively. Based on Cohen's kappa coefficient (κ), the agreement between the two tests was 97%, which was statistically significant (P < 0.001). The detection limit for the One-Step LAMP assay was 1 × 101 copies of standard SARS-CoV-2 RNA per reaction in less than an hour in triplicates. Negative results in all samples with non-SARS-CoV-2 templates represent 100% specificity. CONCLUSIONS: The results showed that the One-Step LAMP assay is an efficient consistent technique for detecting SARS-CoV-2 among suspected individuals due to its simplicity, speed, low cost, sensitivity, and specificity. Therefore, it has great potential as a useful diagnostic tool for disease epidemic control, timely treatment, and public health protection, especially in poor and underdeveloped countries.

BACKGROUND: Nurses who play the leading role in caring for patients, especially nurses in the chemotherapy department who are constantly exposed to high-risk drugs and their side effects, should pay more attention to occupational safety. This study was performed to determine the effect of training chemotherapy safety standards using a smartphone application on nurses' knowledge, attitude, and performance. METHODS: The whole enumeration of fifty oncology nurses was recruited who they worked in 3 hospitals affiliated with Lorestan University of Medical Sciences (west of Iran). The study was conducted from June to November 2021. The training was done for four weeks with a smartphone application, including six main courses of familiarity with hazardous drugs, Personal Protective Equipment, preparation, storage and transfer, spilling, and wastes disposal of hazardous drudges . The nurses' knowledge, attitude, and performance questionnaire were completed before, immediately after, and one month after the intervention. Data analysis was performed using SPSS version 26, descriptive and inferential statistical tests of independent t-test, one-way analysis of variance, Spearman's rank correlation coefficient, repeated measures analysis of variance, and the Generalized Estimating Equation (GEE) model. RESULTS: Mean knowledge score of participants before, immediately after, and one month after the intervention was (47.18 ± 8.19), (60.08 ± 3.82), and (61.88 ± 3.45), respectively. The mean attitude score of participants before, immediately after, and one month after the intervention was (30.34 ± 3.94), (34.32 ± 3.25), and (34.98 ± 2.88), in order, and the mean performance score of participants before, immediately after, and one month after the intervention was (43.60 ± 5.11), (51.78 ± 3.15) and (52.88 ± 3.06), respectively. The mean nurses' knowledge, attitude, and performance score increased significantly over time (P < 0.001). CONCLUSIONS: Teaching chemotherapy safety standards using the application improved oncology nurses' knowledge, attitude, and performance. Appropriate educational programs, especially by new methods such as E-learning, are recommended for providing safety for nurses.
RESUMEN
BACKGROUND: The polymorphisms of fatty acid-binding protein 2 (FABP2) and C-reactive protein (CRP) might act as genetic risk factors for atherosclerosis. The study aimed to investigate the relationship between FABP2 Ala54Thr and CRP+1059C/G polymorphisms and atherosclerosis as well as the association of Small dense-LDL (sd-LDL). METHODS: A total of 255 subjects (125 controls and 130 patients) were included. The FABP2 and CRP polymorphisms were determined by PCR-RFLP and AS-PCR methods, respectively. Sd-LDL was measured based on Hirano et al method. RESULTS: There were no significant distinctions between the patient and control groups concerning FABP2 and CRP polymorphisms (p > .05). No significant relationship was observed between studied polymorphisms and sd-LDL level in the patient group (p > .05). However, patients group had higher level of sd-LDL compared to controls (p < .05). CONCLUSION: FABP2 Ala54Thr and CRP+1059G/C polymorphisms were not associated with atherosclerosis and sd-LDL level. However, the increased sd-LDL level was known as a risk factor for atherosclerosis.

BACKGROUND: Adhesion molecules like E-selectin have important role in pathogenesis of atherosclerosis. C1901T and G98T polymorphisms of E-selectin gene and E-selectin serum level may affect the risk of coronary artery disease (CAD). METHODS: A total of 145 normal individuals and 154 patients diagnosed with CAD from the Lur population of Iran undergoing coronary angiography were enrolled. Genetic polymorphisms of E-selectin were determined using PCR-RFLP. Serum level of soluble E-selectin was measured using Elisa. RESULTS: T allele in C1901T polymorphism was significantly associated with an increased risk of atherosclerosis (P = 0.018). No significant association was observed for G98T polymorphism. The mean serum level of soluble E-selectin in the patient group was significantly higher than the control group (P < 0.001). CONCLUSIONS: Allele type in C1901T polymorphism plays a role in increasing the risk of developing CAD. Furthermore, since serum E-selectin level is associated with systemic inflammation, it contributes to the increased risk of the disease.

BACKGROUND: Comorbidities in heart failure (HF) are a complex clinical challenge. There is little data on the benefits of multidisciplinary postdischarge management programs in such patients. This study aimed to examine the effects of a multidisciplinary management program (MMP) on symptom burden and medication adherence in HF patients with comorbidities. METHODS: In this clinical trial study, 94 HF patients with comorbidities were assigned to intervention (n = 47) and control (n = 47) groups by the stratified-random method. The intervention group underwent MMP supervised by a nurse for two months after discharge, including multi-professional visits, telephone follow-ups, and an educational booklet. Medication adherence and symptom burden were assessed using Morisky Medication Adherence Scale (MMAS) and Edmonton Symptom Assessment Scale (ESAS), respectively, on three occasions: Before discharge, six weeks, and eight weeks after discharge. RESULTS: Both groups almost matched at the baseline, and the most frequent comorbidities included myocardial infarction (MI), hypertension, peptic ulcer, and depression, respectively. The interactive effect of time in groups showed that mean changes in total scores of symptom burden and medication adherence were significantly different (P < 0.001) at other time points. A significant increase in medication adherence (P < 0.001) and a significant reduction in the burden of all symptoms were observed in the intervention group compared to the control group from Time 1 to Time 3. CONCLUSIONS: The MMP (targeting comorbidity) is a promising strategy for managing symptoms and medication adherence in HF patients with comorbidities.

RESUMEN
BACKGROUND: Coronavirus-2019 (COVID-2019) is a novel coronavirus known as Acute Respiratory Syndrome (SARS-CoV-2). The premier standard test for SARS-CoV-2 diagnosis is a one-step RT-qPCR method, which requires specific probes and reagents. Therefore, detection on a large scale is expensive and cannot be very accurate. METHODS: A cost-effective technique based on SYBR green was evaluated in the current study. The specific primers for S and N genes were designed, then performed the cross-reactivity test with other coronavirus and respiratory viruses positive samples. Moreover, the analytical sensitivity test was carried out with 8 dilutions (1:10). Lastly, the SARS-CoV-2 clinical samples (n = 210) were tested by these two methods, and receiver operating characteristic (ROC) analysis was performed to investigate the incremental diagnostic value of each gene in the study methods. RESULTS: The two-step method detected up to 6th dilutions of the SARS-CoV-2 samples and did not show any amplification of the positive samples of other respiratory viruses. ROC analysis revealed a diagnostic ability of the two-step method for SARS-CoV-2 with an area under the ROC curve of ≥ 0.7 (P Ë 0.05) and relatively high sensitivity and specificity. The combination of N and S genes increased the sensitivity up to 88%, specificity up to 86%, and area under the ROC curve up to 0.85 (95% confidence interval (95% CI) 0.72 to 0.93, P = 0.0461). CONCLUSION: Our findings indicated that the two-step method has comparable sensitivity and specificity to the one-step method. Therefore, this method can be considered a potential diagnostic method for diagnosing and monitoring COVID-19 patients. It suggests that when the one-step RT-qPCR method is not available, the two-step RT-qPCR can be used to identify SARS-CoV-2.

Objective: Carbapenems are beta-lactam antibiotics that can play an important role in infections with multiple and severe resistance. The aim of this study was to investigate the frequency of carbapenem-producing bacteria in gram-negative isolates of clinical samples obtained from patients. Methods: 291 g-negative bacilli were isolated from the samples of hospitalized patients using gram staining method, conventional methods and biochemical tests. The antibiotic susceptibility of the isolates was determined using the agar disk diffusion method for 5 different antibiotics. Strains that were resistant to Meropenem antibiotic, KPC enzyme production was examined by the Modified Hodge test method. Results: Out of 291 g-negative bacilli, 14 isolates showed resistance to Meropenem by a disk agar diffusion method where 12 (85.8%) strains were producing KPC enzyme. The highest frequency of Gram-negative KPC-producing bacilli was related to Klebsiella pneumoniae and the most positive samples were urine. The prevalence of this type of bacteria was highest in NICU and the male internal ward, respectively. Conclusion: It was shown that carbapenem-resistant strains are considered as a growing problem in hospitals, especially in the intensive care unit for children and men.
RESUMEN
OBJECTIVE: Smoking is one significant global health care problems, that not only affects the users but also endangers the health of people inhaling the smoke (passive smoking/secondhand smoke). The serum level of IL-18, an important regulator of inherent and acquired immune response, is affected by cigarette smoking. The aim of this study was to evaluate the effect of secondhand smoke (SHS) exposure on IL-18 serum level in non-smoker adults. METHODS: In a case-control study, using easy sampling method, 76 non-smokers who were exposed to cigarette smoke for at least 1 h daily during the past year were considered as exposure group, while 76 of their companions without exposure to cigarette smoke (after matching age) were considered as non-exposure group. Serum IL-18 levels were measured for all participants and finally compared between the two groups using Chi-square test. P value < 0.05 was considered to be statistically significant. RESULTS: The exposure and non-exposure groups included 58 (76.3%) and 25 (32.9%) males, respectively (P < 0.001). The mean ± SD of age for the exposure and non-exposure groups was 35.42 ± 10.37 and 38.47 ± 12.49 years, respectively (P = 0.102). There was no significant difference between the mean serum levels of IL-18 in the exposure (54.81 ± 57.03 ng/ml) and non-exposure (41.49 ± 42.14 ng/ml) groups (P = 0.104). CONCLUSION: The exposure to secondhand smoke has no significant effect on serum level of IL-18 in exposed adult individuals. However, more studies with larger sample sizes on different populations are required to confirm these results.
RESUMEN
BACKGROUND: The nurses' moral sensitivity is the first step to make right decisions in difficult moral situations. Therefore, its education and promotion is highly important. RESEARCH OBJECTIVES: The aim of this study was to examine the impact of poetry-based ethics education on the nurses' moral sensitivity. RESEARCH DESIGN AND METHODS: This was a semi-experimental study. The sample consisted of 108 nurses who were selected by convenience sampling method and randomly assigned to three groups: intervention with poetry (G1), who read a booklet about values and principles of professional ethics as well as poems related to these subjects for 1 month; intervention without poetry (G2), who only read the booklet without any poetry; and control group (G3), who did not receive any intervention. Data were collected by Moral Sensitivity Questionnaire that was completed by the participants prior to the intervention (T1), 1-month post-intervention (T2), and 2-month post-intervention (T3). Data were analyzed by SPSS 16 software. ETHICAL CONSIDERATIONS: This study was conducted in accord with the principles of research ethics and regulations relating to informed consent. FINDINGS: Changes in the mean score of total moral sensitivity were significantly higher in G1 than in G2, which was in turn significantly higher than in G3. This increase was significant from T1 to T2 and T2 to T3 (P < 0.001). In all subscales, there was a significant difference between the mean changes in the three groups, so that in these subscales, the mean changes in G1 were significantly higher than those in other groups. DISCUSSION: In line with previous studies, our results showed the effectiveness of poetry-based education on the transfer of educational concepts and increase moral sensitivity scores with greater lasting effect. CONCLUSION: The use of interdisciplinary subjects such as poetry, due to its entertaining, fun, and lasting effect on minds; level of awareness; and actions of nurses, can help raise nursing moral sensitivity.

Stress and hemodynamic changes are among the most significant symptoms and signs that could be observed in patients with acute coronary syndrome (ACS) upon admission to the emergency department. The present study was conducted to determine the effect of the fragrance of lemon balm (Melissa Officinalis) essential oil on stress level and hemodynamic parameters in patients with ACS in the emergency department. METHODS: In this double-blind clinical trial, 72 patients were allocated to two groups of Melissa and placebo based on stratified block random sampling. The Melissa group inhaled two drops of Melissa essential oil, whereas the placebo group inhaled two drops of sunflower oil in two aromatherapy phases for 10 min with 90-min intervals. Stress level was measured using the depression, anxiety and stress scale (DASS-21), and hemodynamic parameters were measured and recorded in six time points by a cardiac monitoring system. Data analysis was carried out using descriptive statistics and ANOVA statistical tests, Chi-square test, independent t-test, and post-hoc Tukey's test. RESULTS: Interaction between the time and group indicated the significant decrease in the mean score of stress and heart rate in the time points 2 and 5 (5 min after every occasion of aromatherapy) (p < 0.001) and also the remarkable decrease in the mean arterial pressure (MAP) in the time point 2 in the Melissa group in comparison with the placebo group (p < 0.001). There were no significant differences between the mean changes in stress, heart rate and MAP in the two group (P > 0.05). CONCLUSION: Aromatherapy via the inhalation of Melissa essential oil with temporary impacts on certain time points could relieve stress and regulate hemodynamic changes in patients with ACS in emergent and acute conditions.

BACKGROUND: The pathophysiology underlying the progression and development of autoimmune conditions, such as Rheumatoid Arthritis (RA), is a result of dysregulations of the immune system. Research has explored the genetic alterations present in RA; however, limited studies have examined the role of Killer cell Immunoglobulin-like Receptors (KIR) and Human Leukocyte Antigen (HLA) molecules in RA. Therefore, the aim of this study was to examine KIR genes, their HLA ligands, and KIR-HLA compounds in patients with RA. METHODS: In this case-control study, a total of 50 patients with RA and 100 healthy individuals were enrolled. DNA samples were evaluated using PCR with sequence specific Primers (PCR-SSP). Odds ratio (OR) with a 95% confidence interval (CI) were reported. RESULTS: Among the KIR genes examined, KIR2DLA (p= 0.0255, OR= 0.389, 95% CI= 0.210-0.722) and KIR2DS4-full (p< 0.0001, OR= 6.163, 95% CI= 3.174-11.968) were observed to have a statistically significant correlation with disease susceptibility to RA. As an inhibitory gene, KIR2DLA was observed to have a protective effect against RA while KIR2DS4-full as an activating gene, was found to increase risk for RA. No significant associations were found between any of the other KIR genotypes, HLA ligands, or KIR-HLA compounds examined in this study to RA susceptibility. CONCLUSION: In this study of RA in the Lur population of Iran, KIR2DS4-full was observed to increase susceptibility to RA, while KIR2DL5A was found to act as a protecting factor based on both the cross Table and regression analyses. Further research should focus on repeating this study in additional populations.
RESUMEN
BACKGROUND: Meeting the learning needs and developing the thinking skills of nursing students in caring for injured patients with complex, emergency, and unpredictable conditions is essential. PURPOSE: The present study aimed to compare the effects of case-based learning (CBL) with multi-episode case studies and lecture-based learning (LBL) on the perceived problem-solving ability and learning motivation of undergraduate nursing students in an emergency care course. METHODS: This study was conducted with a quasi-experimental, within-subjects, pretest-posttest design. Forty-three third-year undergraduate nursing students (as a single cohort) enrolled in the fall semester were selected using convenience sampling. The theoretical course of emergency nursing was taught to them using the LBL method (control group) during the first six weeks of the semester and then using the CBL method (intervention group) during the second six weeks of the semester through multi-episode cases in five steps. Outcomes including perceived problem-solving ability and learning motivation were measured using the Problem-Solving Inventory (PSI) and the Instructional Materials Motivation Scale (IMMS). RESULTS: There was a significant difference (Pâ¯<â¯0.001) between the changes in the total mean score of perceived problem-solving ability and its subscales on the three measurement points, i.e. before lectures (pre-test), after lectures (mid-term test) and after CBL (final test). There was a significant difference between the LBL and CBL groups in terms of the students' total learning motivation score (tâ¯=â¯16.91, Pâ¯=â¯0.000) and all its subscales after the CBL intervention. CONCLUSION: The study suggests that the CBL method applied through multi-episode cases is an effective approach to improving the perceived problem-solving ability and learning motivation of nursing students.
