RESUMEN

Empathy is one of the important components in the patient-nurse relationship. The aim of the study was to explain the culture of empathic care in intensive care unit (ICU) nurses. The present focused ethnographic study was conducted in the cardiac surgery ICU in Tehran. Three methods of observation, interview, and review of existing documents were used to collect data. From data analysis, three cultural models, "Predominance of task-based care over emotion-based care," "Empathy and lack of empathy, two ends of the spectrum of the nurse-patient relationship," and "Empathy, an interactive and reciprocal process," were extracted. The results showed that empathy creates a caring environment where nurses not only understand their patients but also relate to them, and both are affected by it. Policymakers should consider removing barriers as a means of empowering nurses to provide empathic care.

RESUMEN

Background: Stroke is a significant and unpredictable event that affects physical and mental functions. A useful approach to returning to a normal life is to seek out health information. This study aimed to explore the experiences from health information seeking in the stroke survivors and their family caregivers. Methods: This study was carried out using qualitative content analysis. Participants included five stroke survivors and fifteen family caregivers who were selected purposively from the Rofideh Rehabilitation Center and private physiotherapy centers in Tehran. Data were collected from semi-structured interviews. Data analysis was performed using Graneheim and Lundman's method manually in Word software. Sampling was carried out in 2021. Results: Two main categories were extracted 1): adapting and learning resulting from awareness including optimization of living environment and disease management, and 2) fear and inquietude on the information way including confused and insolvent in receiving information, and doubts about the accuracy of information. Conclusion: The health information seeking created adaptability and relative stability in some stroke survivors and their family caregivers. However, in others, there was still a sense of anxiety and uncertainty. Thus, understanding health information seeking experiences helps health policymakers and administrators to provide information and training based on evidence and individual needs of the client and family.

RESUMEN

Vertical transmission of the novel coronavirus 2019 (COVID-19), has been reported in case reports and series, while the data regarding its transmission is still not enough. Thus, presenting different experiences form various regions could help better understand the virus behavior in pregnancy. We herein report a possible vertical transmission of COVID-19 from a mother to the neonate. A 41-year-old mother with signs and symptoms of acute respiratory illness presented with labor pain and vaginal leak at 37 weeks of gestation. She tested positive for COVID-19 using RT-PCR and underwent emergency cesarean section delivery and gave birth to a girl neonate. The baby tested positive for the COVID-19. Although vertical transmission of COVID-19 has not been proved yet, but there are several lines of evidences suggesting it. Paying close attention to the mother and newborn with COVID-19 and long-term follow-up are needed for better understanding of the virus in pregnancy.

RESUMEN

BACKGROUND: Atorvastatin is a member of statins, which has shown positive vascular effects, anti-oxidant, anti-platelet, and anti-apoptotic properties. OBJECTIVE: In this study, we hypothesized that atorvastatin could prevent the neurons lost in the hippocampal dentate gyrus region after transient global Ischemia/Reperfusion (I/R) through its anti- oxidant and anti-apoptotic activities. METHOD: Twenty-four male Wistar rats, 12-13 weeks old and weighing 250-300 g, were divided randomly into four groups: control, I/R, vehicle (I/R treated with NaCl) and experiment (I/R treated with atorvastatin, 10 mg/kg); rats were sacrificed 96 hours after I/R. Quantitative expression of genes (caspase 8, p53, bax, bcl2, cytochrome c) was studied. The MDA level, SOD, CAT, and GPx activities were measured with biochemical tests. To detect apoptotic cells, TUNEL and Nissl staining were performed. Mitochondria were prepared from the hippocampus rats and used for the quantification of mitochondrial ROS, ATP level, GSH content, membrane potential, cytochrome c release, and determination of mitochondrial swelling. RESULTS: Atorvastatin attenuated the overexpression of bax, cytochrome C, p53, and caspase8 mRNAs and induced expression of bcl-2 mRNA (P<0.001). Atorvastatin treatment increased anti-oxidant enzyme levels (P<0.01). Treatment with atorvastatin reduced the number of TUNEL-positive cells. It could decrease the cytochrome c release (P<0.01), inhibit the decrease of MMP (P<0.001) and increase the ATP level (P<0.001) in hippocampal mitochondria compared with the I/R group. CONCLUSION: Atorvastatin treatment in I/R rats decreases oxidative stress, production of ROS, apoptosis rate in neuronal cells, and improves the mitochondrial function. Hence, atorvastatin has a proper neuronal protective effect against the I/R injury in the brain.

RESUMEN

The prefrontal cortex is the largest lobe of the brain and is consequently involved in stroke. There is no comprehensive practical pharmacological strategy for ameliorating prefrontal cortex injury induced by cerebral ischemia. Therefore, we studied the neuroprotective properties of verapamil (Ver) on mitochondrial dysfunction and morphological features of apoptosis in transient global ischemia/reperfusion (I/R). Ninety-six Wistar rats were allocated into four groups: control, I/R, I/R+Ver (10 mg/kg twice 1 hour prior to ischemia and 1 hour after reperfusion phase), and I/R+NaCl (vehicle). Animals were sacrificed, and mitochondrial dysfunction parameters (i.e., mitochondrial swelling, mitochondrial membrane potential, ATP concentration, ROS production, and cytochrome c release), antioxidant defense (i.e., superoxide dismutase, malondialdehyde, glutathione peroxidase, catalase, and caspase-3 activation), and morphological features of apoptosis were determined. The results showed that mitochondrial damage, impairment of antioxidant defense system, and apoptosis were significantly more prevalent in the I/R group in comparison with the other groups. Ver decreased mitochondrial damage by reducing oxidative stress, augmented the activity of antioxidant enzymes in the brain, and decreased apoptosis in the I/R neurons. The current study confirmed the role of oxidative stress and mitochondrial dysfunction in I/R progression and indicated the possible antioxidative mechanism of the neuroprotective activities of Ver.

RESUMEN

BACKGROUND AND PURPOSE: The nursing student requires opportunities to learn within authentic contexts so as to enable safe and competent practice. One strategy to facilitate such learning is the creation of learning situations. A lack of studies on the learning situation in nursing and other health care fields has resulted in insufficient knowledge of the characteristics of the learning situation, its antecedents, and consequences. Nurse educators need to have comprehensive and practical knowledge of the definition and characteristics of the learning situation so as to enable their students to achieve enhanced learning outcomes. The aim of this study was to clarify the concept of the learning situation as it relates to the education of nurses and improve understanding of its characteristics, antecedents, and consequences. METHODS: The Bonis method of concept analysis, as derived from the Rodgers' evolutionary method, provided the framework for analysis. Data collection and analysis were undertaken in two phases: "interdisciplinary" and "intra-disciplinary." The data source was a search of the literature, encompassing nursing and allied health care professions, published from 1975 to 2016. RESULTS: No agreement on the conceptual phenomenon was discovered in the international literature. The concept of a learning situation was used generally in two ways and thus classified into the themes of: "formal/informal learning situation" and "biologic/nonbiologic learning situation." Antecedents to the creation of a learning situation included personal and environmental factors. The characteristics of a learning situation were described in terms of being complex, dynamic, and offering potential and effective learning opportunities. Consequences of the learning situation included enhancement of the students' learning, professionalization, and socialization into the professional role. IMPLICATION FOR PRACTICE: The nurse educator, when considering the application of the concept of a learning situation in their educational planning, must acknowledge that the application of this concept will include the student's clinical learning experiences. More studies are required to determine factors influencing the creation of a successful learning situation from the perspectives of nurse educators and nursing students, clinical nurses and patients.

RESUMEN

AIM: This study investigated the effect of the emotional intelligence education programme on quality of life of haemodialysis patients. BACKGROUND: Nurses need knowledge development regarding the impact of educational strategies on patients' quality of life suffering from chronic diseases. METHODS: A pragmatic quasi-randomized controlled trial was conducted with 47 haemodialysis patients attending a university hospital in an urban area of Iran. The patients were randomly assigned to intervention (n=23) and control (n=24) groups. A socio-demographic questionnaire, the Cyberia-Shrink Emotional Intelligence Questionnaire, and the Kidney Disease Quality of Life-Short Form were used to gather data. The intervention group attended an educational programme on emotional intelligence that consisted of six-group discussion sessions. To ensure the continuity of learning and to measure the subsequent expected behavioural changes, the patients filled out the data collection tools six and 12weeks after the completion of the education programme. RESULTS: The mean score of quality of life in the intervention group was 39.94±15.88 in pre-test, 44.87±16.04 six weeks and 52.47±16.07 at the 12weeks after the intervention (p=0.032). CONCLUSION: The consideration of emotional intelligence educational strategies by nurses requires its incorporation into pre-qualifying nursing degrees and professional development programmes. Nurse managers need to lead nurses for applying emotional intelligence in daily practice with the aim of providing an holistic patient care.

RESUMEN

BACKGROUND: Healthy spousal communication of marital and sexual expectations is one of the most important factors to improve the quality of sexual relations in marriage. OBJECTIVES: This paper has attempted to explore women's expectations of men for having pleasurable sex in a monogamous and steady sexual relationship within the context of Iran. METHODS: In this qualitative study, 20 interviews were conducted in Tehran from December 2013 to May 2014. Participants were recruited using purposive sampling, face-to-face, in-depth, and semistructured interviews. The collected data were analyzed using qualitative conventional content analysis. The research was designed with regard to Lincoln and Guba's four major rigor criteria in qualitative investigation. RESULTS: Women's expectations for having enjoyable sex were classified in two areas: (1) marital components and (2) sexual components. Marital components included romantic relationships, attention, respect and admiration, appreciation, man's loyalty, and having compatibility. Sexual components included enough sexual skills, good sexual function, and commitment to equity in sex. CONCLUSIONS: This research helps to identify women's expectations for having a gratifying sexual relationship and thus contributes to enhanced sexual satisfaction, as well as marital stability and continuity.

RESUMEN

BACKGROUND: Group B Streptococcus (GBS) is a leading cause of serious neonatal infections. Although great progress has been made in preventing prenatal GBS, its colonization rate in different regions of Iran remains unknown. AIM: To determine GBS colonization prevalence and its risk factors among Iranian pregnant women. METHODS: This prospective cross-sectional study was performed on 186 pregnant women, who attended Boo-Ali hospital which is affiliated with Islamic Azad University in Tehran, Iran, from March 2014 to June 2015. The demographic, obstetric and gynecological data were gathered. A recto-vaginal culture was taken from each patient, with a sterile swab, in lithotomy position without using speculum, and vaginal pH was measured. Patients with positive GBS received IV antibiotic therapy during labor (penicillin G 3 gram at first dose then 1.5 gram Q/4h until delivery). Data were analyzed by statistical software SPSS version 21. Statistical tests for differences were performed by Chi-square test. Potential confounding was assessed by logistic regression. Level of significance was set at p<0.05. RESULTS: Twenty-two (11.8%) patients had positive recto-vaginal colonization. No significant differences between colonized and GBS-negative women with regard to age, obstetrics history and socio-economic factor were noticed. In contrast, smoking, history of previous infection with HPV, presence of vulvitis and a vaginal pH>4.5 were associated with GBS colonization (p≤0.05). CONCLUSIONS: With a relatively low prevalence and few significantly correlated factors, it is hardly possible to define a high risk group of pregnant women for GBS colonization. Therefore, thorough measures should be taken in order to prevent infection complications in mothers and neonates in the Iranian population.

RESUMEN

BACKGROUND: Anxiety among patients after surgery can affect their physiological and psychological well-being. The aim of this study was to investigate and compare the effects of Benson's relaxation and rhythmic breathing techniques on postoperative anxiety in candidates for the mastectomy surgery. METHODS: This randomized controlled clinical trial study was conducted with ninety patients in 2013. The patients were hospitalized for the mastectomy surgery in three surgical wards in a teaching hospital, Tehran, Iran. They were randomly assigned into three groups: Benson's relaxation including the cognitive relaxation technique type, rhythmic breathing including the somatic relaxation technique type and control groups. According to the Davidson and Schwartz multi-process theory, the Benson's relaxation and the rhythmic breathing techniques have cognitive and somatic effects, respectively. One day before the surgery, the patients in the intervention groups were trained regarding relaxation and breathing techniques and were asked to perform the techniques under the supervision of the researcher in the night before the surgery. The cognitive somatic anxiety questionnaire was used to measure anxiety before the intervention and half an hour after recovery of consciousness after the surgery. Descriptive and inferential statistics were used for data analysis via the SPSS v.21 software. RESULTS: There were no statistically significant differences between the groups in terms of demographic characteristics. The application of both techniques reduced the level of patients' anxiety after the surgery. The patients in the Benson's relaxation technique group reported only the relief of somatic anxiety. However, the breathing technique patients reported a reduction in both cognitive and somatic anxiety. CONCLUSION: The Benson's relaxation and rhythmic breathing techniques can reduce postoperative anxiety in patients after the mastectomy surgery. Trial Registration Number: IRCT2014042017350N1.

RESUMEN

Background: The identification and management of unmet needs is an essential component of health care for the growing cancer patient population. Information about the prevalence of unmet need can help medical service planning/redesigning. Therefore, this study aimed to identify unmet needs in Iranian patients suffering from cancer. Methods: This cross-sectional correlational study was conducted on 650 cancer patients admitted to the major medical centers in Mashhad and Neyshabur by census sampling. The data was gathered by the Survivor Unmet Needs Survey (SUNS). Data were analyzed using ANOVA, t-test and Pearson correlation. Results: Most of participants were female (56%, n=263) and Mashhad resident (67.1%, n=436). The most common cancers were colorectal (17.8 %, n=116), stomach (13.6%, n=88) and lung (9.4%, n=62), respectively. The highest unmet needs score belonged to work and financial needs (2.46 ± 0.91), and the least was the emotional domain (1.92±0.90). Among demographic factors, a significant relationship was found between resident places (p<0.001), and cancer type (p<0.0001). Conclusion: This is the first study addressing the unmet needs of cancer patients in Iran. It reveals that cancer patients had a relative high number of unmet needs; this shows the necessity of including these factors in the routine assessment of all cancer patients and planning treatment interventions based on their individual's need.

RESUMEN

BACKGROUND: Since life recovery after disasters is a subjective and multifaceted construct influenced by different factors, and survivors' main concerns and experiences are not clear, the researchers intended to explore this process. MATERIALS AND METHODS: This study was conducted in 2011 - 2014 based on the grounded theory approach. Participants were selected by purposeful sampling followed by theoretical sampling to achieve conceptual and theoretical saturation. Data were collected through interviews, observation, focus group discussion, and document reviews. Data were analyzed by Strauss and Corbin's (2008) recommended approach. RESULTS: Transcribed data from 26 interviews (managers, health care providers, and receivers), field notes, and other documents were analyzed, and 1,652 open codes were identified. The codes were categorized, using constant comparative analysis, into five main categories including reactive exposure, subsiding emotions, need for comprehensive health recovery, improvement of normalization (new normality achievement), and contextual factors. The process of life recovery after disaster was also explored. CONCLUSIONS: The results clarified a deep perception of participants' experiences after disaster. The path of life recovery after disasters involves participants' striving to achieve a comprehensive health recovery, which starts with the need for all-inclusive health recovery as a main concern; this is the motivator for a responding strategy. This strategy is participatory, and the process is progressive; achievement of a new normality is the final goal, with new development and levels of empowerment.

RESUMEN

BACKGROUND: Histologically similar tumors may have different prognoses and responses to treatment. These differences are due to molecular differences. Hence, in this review, the biological interaction of breast cancer in several different areas is discussed. In addition, the performance and clinical application of the most widely-recognized biomarkers, metastasis, and recurrences from a biological perspective and current global advances in these areas are addressed. OBJECTIVE: This review provides the performance and clinical application of the most widely-recognized biomarkers, metastasis, and recurrences from the biological perspective and current global advances in these areas. METHODS: PubMed, Scopus, and Google Scholar were searched comprehensively with combinations of the following keywords: "breast cancer," "biological markers," and "clinical." The definition of breast cancer, diagnostic methods, biological markers, and available treatment approaches were extracted from the literature. RESULTS: Estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER-2), and Ki-67 are the most well-known biological markers that have important roles in prognosis and response to therapeutic methods. Some studies showed the response of ER-positive and PR-negative tumors to anti-estrogenic treatment to be lower than ER-positive and PR-positive tumors. Patients with high expression of HER-2 and Ki-67 had a poor prognosis. In addition, recent investigations indicated the roles of new biomarkers, such as VEGF, IGF, P53 and P21, which are associated with many factors, such as age, race, and histological features. CONCLUSION: The objective of scientists, from establishing a relationship between cancer biology infrastructures with clinical manifestations, is to find new ways of prevention and progression inhibition and then possible introduction of less dangerous and better treatments to resolve this dilemma of human society.

RESUMEN

CONTEXT: Bowel obstruction is one of the most common causes of acute abdomen. Because of heterogeneity of patients' population and variety of causes, therapeutic strategies are not standardized, so treatment of intestinal obstruction is a surgical challenge in many cases. A traditional medicine approach could help detect some issues that were ignored by modern medicine. One of the major schools of medicine, with a history of several thousand years, is Iranian traditional medicine. In this regard, Avicenna, who lived in the medieval period, has had a great influence on the medical knowledge of the world by writing an encyclopedia of medicine entitled "Qanun of Medicine." EVIDENCE ACQUISITION: The aim of this study was to investigate Avicenna's views on the causes of intestinal obstruction and comparing them to modern medicine views. This is a review study on an Iranian traditional textbook of medicine by Avicenna, entitled "Qanun of Medicine" (in short "Qanun"). We used Qanun in its original language (Arabic) along with its Persian translation. It consists of 5 books. Part 16 of the third book talks about intestinal anatomy and introduces some intestinal diseases such as "qoolinj" and "ilavos." Intestinal obstruction can be a kind of "qoolinj" or "ilavos" disease. All intestinal obstruction etiologies in Qanun are searched in international and Iranian databases (Scopus, ISI, SID, and Iranmedex) and similar causes in modern medicine will be discussed in this article. RESULTS: According to Qanun, 16 causes are involved in intestinal etiologies of bowel obstruction such as "reeh," mucoid phlegm, abdominal hot and dry distemperament, decreased bile secretion, job, and so on while modern medicine considers some of them, for instance, volvulus, intestinal herniation, worm, intestinal pseudo-obstruction, and opiate. CONCLUSIONS: Attention to the similar causes of intestinal obstruction in modern medicine and traditional medicine is the starting point for investigation of noninvasive diagnostic and therapeutic methods that have been mentioned in Qanun. In addition, etiologies which are missed in modern medicine can open new doors to the researchers and gastroenterologists for the study, diagnosis, and prevention of the disease.

RESUMEN

Breast cancer is the most common malignancy and also the second leading cause of cancer death among women and also in women that have a high mortality. Previous studies showed that magnesium (Mg) has cytotoxic effects on malignant cell lines. However, the anti-cancer effects of Mg on MCF-7 breast cancer cells are uncertain. This study was aimed at the comparison of the cytotoxic effect of Mg salt (MgCl2) and cisplatin on MCF-7 cells and fibroblasts (as normal cells). After treatment with various concentrations of MgCl2, and cisplatin as a positive control for 24 and 48 hours (h), cytotoxicity activity was measured by MTT assay. In addition, apoptosis was determined by annexin V/propidium iide assay. Both cisplatin and the MgCl2 exhibited dose-dependent cytotoxic effects in the MCF-7 cell line, although the LD50 of the Mg was significantly higher when compared to cispaltin (40 µg/ml vs. 20 µg/ml). Regarding annexin V/propidium results, treatment of MCF-7 cells with LD50 concentrations of cisplatin and Mg showed 59% and 44% apoptosis at 24h, respectively. Finally, the results indicated that Mg has cytotoxic effects on MCF-7 cells, but less than cisplatin as a conventional chemotherapeutic agent. However, regarding the side effects of chemotherapy drugs, it seems that Mg can be considered as a supplement for the treatment of breast cancer.

RESUMEN

This study was aimed at evaluating the protective effect of coenzyme Q10 on L-arginine-induced acute pancreatitis in rats regarding biomarkers and morphologic changes. Thirty-two male Sprague-Dawley rats were divided into 4 equal groups. Control group received intraperitoneal normal saline, while in sham and experimental groups 1 and 2 pancreatitis was induced with L-arginine. E1 and E2 groups were treated with a single dose of 100 and 200 mg/kg Q10, respectively. Serum lipase and amylase, along with pancreas IL-10, IL-1ß, and TNF-α, were measured. For evaluation of oxidative stress, pancreatic superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and myeloperoxidase (MPO) were assessed. Histopathological examination for morphologic investigation was conducted. Serum amylase and lipase, as well as TNF-α and IL-1ß cytokines, reverted with administration of Q10 in consistence with dosage. In contrast, Q10 assisted in boosting of IL-10 with higher dosage (200 mg/kg). A similar pattern for oxidative stress markers was noticed. Both MDA and MPO levels declined with increased dosage, contrary to elevation of SOD and GSH. Histopathology was in favor of protective effects of Q10. Our findings proved the amelioration of pancreatic injury by Q10, which suggest the anti-inflammatory and antioxidant property of Q10 and its potential therapeutic role.

RESUMEN

BACKGROUND: Development of practical skills in the field of nursing education has remained a serious and considerable challenge in nursing education. Moreover, newly graduated nurses may have weak practical skills, which can be a threat to patients' safety. OBJECTIVES: The present study was conducted to compare the effect of concept mapping and conventional methods on nursing students' practical skills. PATIENTS AND METHODS: This quasi-experimental study was conducted on 70 nursing students randomly assigned into two groups of 35 people. The intervention group was taught through concept mapping method, while the control group was taught using conventional method. A two-part instrument was used including a demographic information form and a checklist for direct observation of procedural skills. Descriptive statistics, chi-square, independent samples t-tests and paired t-test were used to analyze data. RESULTS: Before education, no significant differences were observed between the two groups in the three skills of cleaning (P = 0.251), injection (P = 0.185) and sterilizing (P = 0.568). The students mean scores were significantly increased after the education and the difference between pre and post intervention of students mean scores were significant in the both groups (P < 0.001). However, after education, in all three skills the mean scores of the intervention group were significantly higher than the control group (P < 0.001). CONCLUSIONS: Concept mapping was superior to conventional skill teaching methods. It is suggested to use concept mapping in teaching practical courses such as fundamentals of nursing.

RESUMEN

Delayed wound healing process is one of the most important concerns in diabetes. Healing of wounds has four phases, namely, hemostasis, inflammation, proliferation, and remodeling. For a successful repair, all four factors must occur properly. Hence, we aimed to evaluate the healing effects of Hypericum perforatum (HP) on full-thickness diabetic skin wounds by using stereological methods. Forty-eight female diabetic rats were randomly divided into four groups (n = 12): gel base treated group, HP 5% gel treated group, HP 10% gel treated group, and the control group which received no treatment. A circular 1 cm(2) full-thickness wound was created on the animal's neck and wound area was measured every three days. After sacrificing the animals, skin samples were fixed and prepared for stereological evaluations. Based on the results, HP treated group showed faster wound closure rate in comparison with control and vehicle groups (P < 0.05). In addition, numerical density of fibroblasts, volume density of collagen bundles, and mean diameter and volume densities of the vessels in HP group were significantly higher than control and vehicle groups. The results of this study showed that HP has the ability to improve tissue regeneration by enhancing fibroblast proliferation, collagen bundle synthesis, and revascularization.

RESUMEN

BACKGROUND: Sexual satisfaction is considered to be a sexual right and an important component of sexual health. The purpose of this qualitative study was to clarify the meaning and the nature of sexual satisfaction in Iranian married women, and to provide a cultural-based definition of it. METHOD: Sexual satisfaction was examined in three phases by the Hybrid Model of concept analysis: (1) the theoretical phase; (2) the fieldwork phase and (3) the analytical phase. Hybrid concept analysis method was chosen because its inclusion of married women's perspectives enriches the limits of sexual health search literature. RESULT: The critical attributes of sexual satisfaction were investigated. They included 'two-dimensional structure', 'an affective response', 'a means to achieve marital satisfaction', 'unique', 'a concept based on expectations' and 'a concept on shadow of values'. CONCLUSION: The concept analysis of sexual satisfaction showed some of the attributes and antecedents for this concept that, have not been mentioned in the literature.
