The emergence of plasmid-encoded oxacillinase and carbapenemase among uropathogenic Escherichia coli (UPEC) isolated from hospitalized patients in the North of Iran.

Carbapenemase enzyme production is responsible for resistance to carbapenem among Gram-negative bacteria. This study aimed to detect common carbapenemase and oxacilinase genes among uropathogenic E. coli (UPEC) isolated from hospitalized patients in Rasht, north of Iran. In the present study, from 2000 urine samples, 263 UPEC strains were isolated from inpatients with urinary tract infections (UTI) in 2020. The Kirby-Bauer disk diffusion susceptibility test was used to determine the sensitivity or resistance of isolates to antimicrobial compounds. The double-disk test confirmed extended-spectrum ß lactamase (ESBL) production phenotypically, and the presence and distribution of genes encoding carbapenemase and oxacilinase were investigated using polymerase chain reaction (PCR). Based on the findings, 13/263 isolates (8 ESBL and five non-ESBL) showed a non-susceptible phenotype to at least one of the studied carbapenem group antibiotics, and 121 (46%) isolates were ESBL-producers. PCR for oxacilinase and carbapenemase genes was done on all 126 isolates, including ESBL-positive and carbapenem-resistant strains, in which 10 (7.9%) and 25 (19.8%) isolates harbored OXA-1 and IMP genes, respectively. Also, OXA-2, OXA-10, OXA-48, VIM, and NDM genes were not found in any studied isolates. IMP and OXA-1 genes among carbapenemase-producing isolates indicate the possible spread of antibiotic-resistant strains. Hence, identification and control of ESBL and carbapenemase-producing strains, although with almost low frequency due to plasmid genes encoding carbapenemase, is essential for infection control.

Molecular detection of Toxoplasma gondii in chicken hearts from markets and retail stores in Northern Iran.

Detection of Toxoplasma gondii in chicken products indicates risk of transmission to consumers. The objective of the current study was to investigate the molecular prevalence of T. gondii in free-ranging and industrial chickens in Guilan province, Northern Iran. A total of 150 chicken heart samples including 75 free-range and 75 industrial chickens were collected from farmers' markets and chicken retailers in Guilan, Northern Iran, between October 2017 and August 2018. Genomic DNA were extracted from samples and examined for evidence of T. gondii using polymerase chain reaction (PCR) targeting the B1 gene. The B1-positive samples were further analyzed by nested-PCR for SAG1 gene. Of the 150 samples, T. gondii DNA fragments were detected in 59 (39.3%), including 30 (40%) free-range and 29 (38.7%) industrial chicken. No significant differences of T. gondii DNA detection was observed between the free-range and industrial chicken samples (p = 0.73). Four selected positive samples were used for amplifying and sequencing of the SAG1 gene. The results revealed that all four sequences of SAG1 had 100% similarity with T. gondii sequences previously isolated from an AIDS/HIV patient in Mazandaran province, Northern Iran. Furthermore, the phylogenetic analysis demonstrated that all four sequences were closely related to Type I of T. gondii. However, our Type I identification is preliminary and needs to be confirmed by further multilocus sequence typing (MLST) analysis. The findings of the present study provide new data about the presence of T. gondii DNA in chicken hearts in the study area. These results confirm that chicken can be used as sentinels for environment contamination; however, further studies are needed to determine the viability of T. gondii in chicken hearts from Iran for risk assessment.

Evaluation of hematological indices among insecticides factory workers.

Insecticides are commonly used pesticides in the world. Chronic exposure to insecticides has adverse effects on various human body organs. In this study, hematological findings were assessed in workers in an insecticide manufacturing plant. Hematological parameters and clinical symptoms were recorded in 99 workers exposed to insecticides and 107 workers not exposed to them in a cross-sectional study. Assessment of the hematological results showed a higher prevalence of thrombocytosis in the exposed group than the non-exposed group (P < 0.05). Mean white blood cell (WBC) and platelet counts, anisocytosis of red blood cells (RBCs), and neutrophils to lymphocytes ratio (NLR) were significantly higher in the exposed group compared to the non-exposed group (P < 0.05). Prevalence rates of headache, itchy skin, cough, and sleep disorders were higher in the exposed group than in the non-exposed group (P < 0.05). Chronic exposure to insecticides can alter hematological parameters in the normal range. Occupational exposure to insecticides may increase WBCs, platelet count, NLR, and red cell distribution width (RDW). It can also cause thrombocytosis. Complete blood count (CBC), as an inexpensive and accessible tool, can help monitor workers' health status exposed to insecticides properly.

A survey on the seroprevalence of toxocariasis and related risk factors in Eosinophilic children of Northwest Iran.

Background: Toxocariasis is a serious zoonotic helminthic disease caused by the nematodes; Toxocara species. Aim: A cross-sectional study was conducted to determine the seroprevalence of toxocariasis and related risk factors in eosinophilic children referred to the pediatrics hospital of Qazvin province northwest Iran during 2019-2020. Methods: A total of 200 blood samples were collected from eosinophilic children referred to the Qods Pediatrics Hospital. Demographic data, clinical symptoms, and dogs- and soil-contact history were collected. The presence of anti-Toxocara IgG antibody was evaluated by T. canis IgG ELISA kit. Results: Anti-Toxocara IgG antibodies were detected in 14 (7%) of the total eosinophilic children. The seropositive rate of toxocariasis in hyper-eosinophilic children (>1000/mm3) was 15.1%, while the seropositivity was 4.1% in children with eosinophilia status (500-999/mm3). There was a significant association between the eosinophilia rate and seropositivity (P<0.05). Also, seroprevalence in asymptomatic eosinophilic children was 4.4%, while in children with clinical symptoms it was 17.1%. Accordingly, a statistically significant difference was found between clinical symptoms and Toxocara infection (P<0.05). Conclusion: The prevalence of toxocariasis in eosinophilic children is a serious health problem in the study area. Therefore, serologic evaluation for the diagnosis of Toxocara infection is recommended for eosinophilic children.

The effect of education using a mobile application on knowledge and decision of Iranian mothers about prevention of foreign body aspiration and to relieve choking in children: A quasi-experimental study.

PURPOSE: The aim of this study was to determine the effect of mobile-based education on mothers' knowledge and decisions about prevention of foreign body (FBA) aspiration and to relieve choking in preschool children. METHODS: This is a quasi-experimental study in which 88 mothers whose children were registered in each selected kindergarten of the city of Rasht (in Iran) were selected by multi-stage cluster sampling. All mothers were educated through lectures. Then, in the control group, an educational booklet and CDs were used, and in the intervention group, a mobile application was used. Mothers' knowledge and decision were measured by a researcher-made questionnaire before and after the lecture and four weeks after providing the interventions. Mann-Whitney, Wilcoxon, and Friedman tests were used to analyze the data. The level of significance was p < 0.05. RESULTS: The results showed that the mean scores of knowledge (n = 44, M = 13.47, SD = 1.84) and decision (n = 44, M = 8.52, SD = 1.30) of participants immediately and mean scores of knowledge (n = 44, M = 14.68, SD = 1.98) and decision of participants (n = 44, M = 9.56, SD = 2.15) four weeks after the educational interventions, in the intervention group, were statistically significantly higher than the control group. Intragroup comparison of the mean scores of knowledge and decision immediately and four weeks after educational interventions, showed that only in the intervention group did the mean scores have statistically significant increase, (p < 0.05). CONCLUSION: Mobile-based education was more effective in improving mothers' knowledge and decision about prevention of foreign body aspiration and to relieve choking in children than other educational methods. PRACTICE IMPLICATIONS: Mobile applications may be a new and effective method for providing education to parents.

The effect of virtual reality distraction on reducing patients' anxiety before coronary angiography: a randomized clinical trial study.

BACKGROUND: Coronary angiography is used as a qualified method to diagnose coronary heart disease. However, patients undergoing coronary angiography experience a great deal of anxiety. The present study is aimed at investigating the effect of virtual reality on anxiety before coronary angiography. In a randomized controlled trial, 60 candidates for coronary angiography were randomly assigned to two intervention and control groups from April to July 2019. Data were collected by Spielberger's situational anxiety questionnaire. The participants' anxiety level and their heart rate, respiratory rate, and blood pressure were measured before and immediately after the intervention. The Intervention group received virtual reality intervention, and the control group was cared for based on the hospital routine. Data were entered into the SPSS version 24.0 software (SPSS Inc.) and analyzed using Chi-square, Paired samples, and independent sample t tests. RESULTS: The majority of participants were male (71.25%) and the Mean ± SD age of them in the intervention and control groups was 50.95 ± 4.120 and 52.08 ± 4.002 years, respectively. The mean score of anxiety (p < 0.01), heart rate (p = 0.001), and systolic blood pressure (p = 0.016) after the intervention in the intervention group decreased significantly. CONCLUSIONS: This study indicated the implementation of a VR distraction protocol in the patients could effectively reduce perioperative anxiety and its indices. It showed that VR is a safe method without any complications related to the device and with good acceptability. Registration code IRCT201 40515017693N3.

The effect of massage therapy on fatigue after chemotherapy in gastrointestinal cancer patients.

INTRODUCTION: Gastrointestinal cancer patients undergoing chemotherapy usually suffer from fatigue, which may affect different aspects of their lives. OBJECTIVE: The current study aimed to investigate the effect of massage therapy on fatigue after chemotherapy in gastrointestinal cancer patients. METHOD: In this quasi-experimental study, 88 gastrointestinal cancer patients were randomly allocated into two groups of intervention and control. Patients received the chemotherapy for 3 h. The intervention group received four sessions of foot massage with an interval of 40 min during the chemotherapy. The massage duration was 7 min for each foot. Fatigue was measured using the visual analogue scale to evaluate fatigue severity just after and 24 h after the chemotherapy. Friedman and Mann-Whitney U tests were used to analyze the data. RESULTS: The mean age of patients was 59/18 ± 9/35, and the most common type of cancer was gastric cancer (40%). There was a significant difference in the mean score of fatigue between the two groups immediately after (P > 0.001) and 24 h after chemotherapy (P < 0.001). In the intervention group, fatigue score decreased gradually (P = 0.031), while it increased in the control group (P = 0.001). CONCLUSION: This study demonstrated that foot massage, as a simple method, could reduce chemotherapy-induced fatigue.

Comparing the Effects of Mobile-Based Education and Booklet-Based Education on Iranian Mothers' Perception on Antibiotics: A Quasi-Experimental Study.

PURPOSE: The aim of this study was to investigate the effect of mobile-based education in comparison with booklet-based education on mothers' perception on antibiotics. DESIGN AND METHODS: This quasi-experimental study was performed on 160 mothers of children aged 1 to 6 years (80 in the experimental group and 80 in the control group) who referred to the urban community health centers in Iran. Both groups were taught about the proper use of antibiotics. The experimental group was taught using a mobile application and the control group was taught using a booklet. The Parental Perception on Antibiotics (PAPA) scale was used to collect data at the beginning and two to four weeks after the educational intervention. The data were analyzed using SPSS version 19. RESULTS: The results showed that 91.9% of mothers used the knowledge of nurses or other health care providers and 86.3% used their previous experience as the source of information about antibiotics. Also, mothers' perceptions about antibiotics in the subscales of knowledge and beliefs, behaviors, adherence and awareness about antibiotics resistance in the experimental group improved significantly compared to the control group (p < 0.05). CONCLUSIONS: Mobile-based education was more effective in improving mothers' perception on antibiotics than booklet-based education. PRACTICE IMPLICATIONS: Health care providers can use mobile-based educational method for different groups of society to promote health in various fields.

The effect of seasonality on reproductive outcome of patients undergoing intracytoplasmic sperm injection: A descriptive cross-sectional study.

BACKGROUND: There is conflicting evidence regarding the impact of season on the assisted reproductive technology outcome. OBJECTIVE: To retrospectively compare three year outcome of women undergoing their first intracytoplasmic sperm injection cycle, across seasons. MATERIALS AND METHODS: In this descriptive cross-sectional study, 3,670 women who underwent their first intracytoplasmic sperm injection cycle in Mehr Medical Institute, Rasht, Iran between April 2010 and May 2014 were studied. Women were divided into four groups according to the day of oocyte retrival as: spring (n = 808), summer (n = 994), autumn (n = 1066), and winter (n = 802). Basal and stimulation charecteristics were compared among groups. RESULTS: While sperm concentration and motility were significantly lower during summer, the total number of retrieved and metaphase II oocytes were significantly higher (p = 0.0001, p = 0.0001, p = 0.004, p = 0.02, respectively). Fertilization rate were significantly higher during autumn (p = 0.0001). Also, the number of high- quality transferred embryos were significantly higher during summer and winter (p = 0.03). A similar pattern was observed in implantation rate and pregnancy over the four seasons. CONCLUSION: Despite the fact that intracytoplasmic sperm injection minimize the seasonal effect on pregnancy outcome, changes in pregnancy rate still occur among different seasons without particular pattern. It seems that performing assisted reproductive technology procedures in a particular season should be considered as an effective factor.

Hemodynamic parameters and reproductive outcome after intracytoplasmic sperm injection and fresh embryo transfer in patients undergoing oocyte retrieval with general anesthesia using fentanyl, remifentanil or alfentanil - A randomized clinical trial.

OBJECTIVE: Anesthesia for assisted reproductive technology is very important to provide less stressful and painful environment for patients, with minimal side effects on oocytes. In the present study, we aimed to evaluate hemodynamic parameters, recovery time and intracytoplasmic sperm injection (ICSI) outcome among patients underwent anesthesia with fentanyl, remifentanil or alfentanil. MATERIAL AND METHODS: This randomized double-blinded clinical trial was conducted in patients undergoing anesthesia for transvaginal ultrasound guided oocyte retrieval (TUGOR). Patients were randomly allocated to alfentanil (A; 15 µg/kg), fentanyl (F; 1.5 µg/kg) or remifentanil (R; 1.5 µg/kg) groups. RESULTS: Three hundred forty patients were assessed for eligibility and randomized for transvaginal oocyte retrieval following general anesthesia and 105 were lost to follow up. No statistically significant differences were noted among groups regarding basic characteristics. Although, time to respond to verbal command was significantly different among groups (A: 1.99 ± 1.64, F: 2.56 ± 1.72, R: 1.78 ± 1.34, P = 0.014). There were no significant differences among groups with respect to the first and second postoperative pain intensity, patient satisfaction, pre-induction and post-induction systolic and diastolic blood pressure (BP). Terminal systolic (A: 101.61 ± 9.15, F: 105.29 ± 12.61, R: 102 ± 12.91, P = 0.01) and diastolic (A: 59.97 ± 9, F: 65.63 ± 9.13, R: 63.69 ± 11.01, P = 0.003) BP was significantly different among groups. The fertilization rate was significantly different among groups (A: 51.6%, F: 54.4%, R: 62.2%, P = 0.018). Implantation rate, biochemical and clinical pregnancy rate was similar among groups. CONCLUSIONS: The results of present study demonstrated that all three opioids have the same efficiency, in regards to patient satisfaction and pregnancy outcome. However, Anesthesia with alfentanil compared with fentanyl and remifentanil, seems to be inferior for TUGOR due to higher effect on fertilization rate and less hemodynamic stability.

Exacerbation causes among inflammatory bowel disease patients in Guilan Province north of Iran / Causas de exacerbação entre pacientes com doença inflamatória intestinal na província de Guilan, norte do Irã

ABSTRACT Objective: Numerous factors may contribute as triggers to the exacerbation of the condition of patients with inflammatory bowel disease. Methods: The medical files of 109 patients with the positive history of inflammatory bowel disease exacerbation between March 2016 and March 2017 were assessed retrospectively. Data were obtained using the inflammatory bowel disease data bank software. The parameters were obtained from the inflammatory bowel disease data bank software. The mentioned parameters were assessed in terms of type and severity of disease using chi-square test in SPSS software. Moreover, binary logistic regression test was used to assess the associations between season of disease onset and inflammatory bowel disease exacerbation as odds ratios with 95% confidence intervals (95% CI). Results: Overall, (88.1%) of cases with inflammatory bowel disease exacerbation, had ulcerative colitis. The mean age of patients was 38.14 ± 14.66 years. The disease duration in all patients (ulcerative colitis and Crohn's disease) was 35.43 and 38.85 months, respectively. About 50% of patients with infection were strongyloides stercoralis positive. The occurrence of mild inflammatory bowel disease exacerbation was significantly higher in spring in comparison to other seasons (OR = 3.58; 95% CI 0.1-1.04). Most patients with ulcerative colitis were prescribed salicylates alone (53.12%). Most patients with Crohn's disease with mild and severe activity were non-smokers (p = 0.058). This difference was marginally significant. Conclusion: It is suggested that in future studies, the evidences of distribution of SS infections among patients with inflammatory bowel disease and the history of exacerbation along with other environmental factors such as enhancing nutritional quality and surface water be taken into consideration.

RESUMO Objetivo: Em pacientes com doença inflamatória intestinal, vários fatores podem servir como gatilhos para a exacerbação do quadro. Métodos: Os prontuários de 109 pacientes com história de exacerbação da doença inflamatória intestinal entre março de 2016 e março de 2017 foram avaliados retrospectivamente. Os dados foram obtidos usando o software do banco de dados sobre doença inflamatória intestinal, que também foi usado para a definição dos parâmetros do estudo. Esses parâmetros foram avaliados quanto ao tipo e severidade da doença usando o teste do qui-quadrado no software SPSS. Além disso, o teste de regressão logística binária foi utilizado para avaliar as associações entre a estação do início da doença e a exacerbação da doença inflamatória intestinal, expressados em razão de probabilidade (odds ratio) com intervalos de confiança de 95% (95% CI). Resultados: No geral, 88,1% dos casos de exacerbação da doença inflamatória intestinal foram observados em pacientes com colite ulcerativa. A média de idade dos pacientes foi de 38,14 ± 14,66 anos. Em todos os pacientes, a duração média da doença (colite ulcerativa e doença de Crohn) foi de 35,43 e 38,85 meses, respectivamente. Cerca de 50% dos casos de infecção apresentaram cultura positiva para Strongyloides stercoralis. A ocorrência de leve exacerbação da doença inflamatória intestinal foi significativamente maior na primavera em comparação com outras estações (OR = 3,58; 95% CI: 0,1-1,04). A maioria dos pacientes com colite ulcerativa foi medicada apenas com salicilatos (53,12%). A maioria dos pacientes com doença de Crohn com atividade classificada como leve ou grave era não fumante (p = 0,058). Essa diferença foi marginalmente significativa. Conclusão: Sugere-se que, em estudos futuros, as evidências de distribuição das infecções por Strongyloides stercoralis em pacientes com doença inflamatória intestinal e história de exacerbação sejam levadas em consideração em conjunto com outros fatores ambientais, como qualidade nutricional e da água de superfície.

Dietary Patterns and Risk of Breast Cancer in Women in Guilan Province, Iran.

BACKGROUND: Several studies have pointed to roles of dietary and food groups in the pathogenesis of breast cancer, but information on dietary patterns among women with breast cancer and their healthy counterparts in Iran is limited. Therefore the present investigation was conducted in Guilan province in 2014-2015. MATERIALS AND METHODS: In a case-control study, 450 women with breast cancer and one of their relatives (third-rank) were investigated. At first the phone numbers of patients in Razi Hospital in radiotherapy and chemotherapy and oncology centers of Guilan were taken. Data were collected through telephone interviews by the researcher. The questionnaire had two parts comprising demographic clinical and food frequency data including a list of 40 food items. To analyze the variables, Chi-square test and univariate logistic regression models were used. RESULTS: In each group, 225 subjects were investigated. The majority of samples in both groups of experiment and control were consumed than two glasses of milk and dairy products per day. Regarding consumption of meat and its products, 56% of the cancer group had more than three servings per day while 26.7% of the control group had less than 2 servings per day. The majority of subjects had less than six servings of cereal per day. Some 54. 7 % of the cancer and 62.2 % of the control group consumed less than two servings of fruit per day. Consumption of vegetables in experimental and control groups were 52.9% and 76.9% respectively, more than five servings per day. There was a meaningful difference between two groups regarding the consumption of milk and dairy items (OR=0.6,95%CI= 0.4-0.9), meat and its products (OR=0.49,95%CI=0.3-0.7), bread and cereals (OR=0.4,95%CI=0.2-0.8), vegetables (OR=0.5,95%CI= 0.3-0.9). (P-value<0.05). CONCLUSIONS: The results of this study emphasize the importance of informing women, particularly those at higher risk of breast cancer, in relation to dietary factors.

Assessment of factors affecting quality of life in diabetic patients in Iran.

OBJECTIVE: Assess the pattern of relationships between personal-background characteristics and dimensions of quality of life (QOL) in diabetic patients. DESIGN: Cross-sectional descriptive study. SAMPLE: 117 adults with type 2 diabetes (100 female, 17 male) randomly selected from outpatients referred to Sina hospital (Tabriz, Iran). METHODS: Participants answered a three-part questionnaire including (1) sociodemographic and medical (diabetes-related) personal-background characteristics; (2) general health-related QOL instrument based on Swedish Health-Related QOL; (3) disease-specific instrument for diabetic patients. Nine QOL dimensions were covered: physical function, pain, daily activities, feelings, sleep, relationships with relatives, overall health, problems with diabetes, satisfaction with diabetes treatment methods. Data were analyzed with inferential statistics, correlation, and multi-stage stepwise regression. RESULTS: Personal background characteristics (age, presence of medically educated people in family, whether patient was family breadwinner, unemployment, complications of diabetes) accounted for 27% of variance in the physical function dimension of QOL dimension. Other QOL dimensions (daily activities, overall health, sleep, satisfaction with diabetes treatment.) were also related to personal background characteristics. CONCLUSIONS: Diabetic patients face great challenges in many dimensions of QOL. Nursing instructors and nursing educators in educational centers for diabetics can use the findings of this research to assess their patients more effectively.
