Correlation between hyponatremia and high risk clinical and echocardiographic features in patients with acute heat failure
Background and purpose: Heart failure (HF) is characterized by decreased ability of the heart to provide sufficient blood flow or fill with the blood. Hyponatremia is the most commonly seen electrolyte abnormality in patients with heart failure that is associated with increased morbidity and mortality. The aim of this study was to assess the correlation between hyponatremia and high risk clinical and echocardiographic features in patients with acute HF. Materials and methods: This cross-sectional analytic study was performed in 271 patients with acute systolic heart failure admitted to Sari Fatemeh Zahra hospital, 2018-2019. Patients were divided into two groups: hyponatremic and normonatremic groups. Vital signs, echocardiographic variables, body mass index (BMI), and common cardiovascular risk factors were compared between the two groups using SPSS V18. Results: This study included 130 males (48) and 141 females (52) and the patients� mean age was 69.90±14.02 years. Patients with hyponatremia had lower BMI and systolic and diastolic blood pressure levels and higher platelet counts compared to other group (P =0.01, 0.002, 0.005, and 0.047, respectively). Also, these patients, were found with higher frequency of moderate to severe functional mitral regurgitation (P= 0.076). Linear regression analysis showed hyponatremia as an independent predictor of hypotension and hemodynamic instability in patients with hyponatremia. Conclusion: This study showed that patients with acute HF and hyponatremia are at higher risk of developing hypotension, cachexia, and increased platelet counts which put them at greater risk for cardiovascular morbidity and mortality. © 2020, Mazandaran University of Medical Sciences.

Motor Exercises Effect on Improving Shoulders Functioning, Functional Ability, Quality of Life, Depression and Anxiety For Women With Breast Cancer
Purpose: This research aimed to study the effects of motor exercises on improving shoulder functioning, functional ability, quality of life, depression, and anxiety in patients. Patients and Methods: A randomized clinical trial in which 70 eligible patients referred to the oncology ward participated in two intervention and control groups. The intervention group (N=35) had been doing motor exercises for five weeks. Before the surgery, two days, and five weeks after surgery, shoulder Range Of Motion (ROM) was measured with a goniometer, and the functional capacity level was measured by the 6-Minute-Walk-Test. Quality of life, depression, and anxiety were measured using the EORTC QLQ-C30 and QLQ-BR23; and HADS questionnaires, respectively, at baseline and five weeks after surgery. Descriptive statistics, the T-test, and the Chi-Square t-hotelling model were used to analyze the data. Results: The results showed that motor exercises had a significant statistical increase in the distance of 6MWT (P<.001) and ROM (P�.001) compared to the control group. Moreover, there were significant differences in dimensions of patients� quality of life, depression, and anxiety in the intervention group, compared to the control group (P<.05). Conclusion: Motor exercises had positive effects on improving physical functioning, shoulder ROM, and decreasing patients� anxiety and depression symptoms, consequently enhancing the quality of life. © 2022 Elsevier Lt
Total delay and associated factors in pulmonary tuberculosis patients in Golestan province
Background: Delay in diagnosis and treatment of TB is a critical component in TB control program which thereby spreading illness in the community. Sicnce Golestan province has the high risk with high rates of tuberculosis in the country, therefore, the analysis of the factors associated with treatment delay in this province for effective interventions and proper planning is considered necessary. Methods: 689 patients documents of TB cases in the health department of Golestan University of Medical Sciences in 2016 were enrolled in this survey. The response variable in this study was having the delay or not (via determining the 34 day as cut-off point in the interval between the date of onset of the symptoms and the date of treatment start-up). The data were analyzed using SPSS 24 software and final significant level for multivariate logistic regression model was considered 0.05. Results: Median (mean) treatment delay was calculated 49(77.75) days. In the current study 60.4 of patients had total delay greater than 34 days. In final model variables such as type of PTB (OR=0.645), contact history (patients who had no contact with TB patients (OR=1.441)) and patients who their contact history were unknown (OR=1.654)) had significant relationship with delay in starting treatment after 34 days of onset of symptoms of PTB patients in Golestan (p<0.05). Conclusion: It should beam emphasis on increasing the community's awareness of the symptoms of tuberculosis and effective collaboration should be made between the Infectious Disease Control Center and the private and public sectors. © 2020 Babol University of Medical Sciences.

In vitro analysis of antifungal effects of acrylic resin modified by zinc oxide nanoparticles on candida albicans
Background and purpose: Removable prostheses made of polymethyl methacrylate are susceptible to Candida-dependent denture stomatitis and Candida albicans is considered to be the first common cause. The aim of the present study was to investigate the antifungal effect of acrylic resin modified by zinc oxide nanoparticles. Materials and methods: In this laboratory study, 72 disks (10*4 mm) made of polymethyl methacrylate (Acropars, Marlic, Iran) were divided into three groups (n= 24). Concentrations of zinc oxide nanoparticles (ZnO NPs) were 1 (group A), 0.5 (group B), and 0 (group C, control) mg/ml. Samples were studied in laboratory using Candida albicans strains (ATCC 10231) according to CLSI M27-A3 and M27-S4 documents. For data analysis, one-way ANOVA and Scheffe's post-test were performed using SPSS V24. Results: There were significant differences in mean numbers of fungal colonies in study groups. The amount of fungal colonies in group A was lower than those in group B and in group B was lower than those in group C (P<0.05). Conclusion: Considering the limitations of this study, findings showed that zinc oxide nanoparticles have antifungal activity, which increases by increase in concentration of nanoparticles. © 2021, Mazandaran University of Medical Sciences.

Genetic diversity and antifungal susceptibility patterns of aspergillus nidulans complex obtained from clinical and environmental sources
The molecular epidemiology and antifungal susceptibility of Aspergillus nidulans species complex has not been well studied. To evaluate the genetic diversity and antifungal susceptibility patterns of clinical and environmental isolates of A. nidulans complex. Sixty clinical and environmental isolates of Aspergillus section Nidulantes were collected from five countries (Iran, The Netherlands, Spain, Portugal and Greece). The species were molecularly identified by sequencing of β-tubulin gene. The genetic diversity of A nidulans complex isolates (n = 54) was determined with a microsatellite genotyping assay. Antifungal susceptibility profile was determined using EUCAST method. The isolates were classified as A nidulans (46.7%), A spinulosporus (26.6%), A quadrilineatus (10%), A pachycristatus (3.3%), A rugulosus (3.3%), A unguis (5%), A creber, (1.7%), A olivicola (1.7%) and A sydowii (1.7%). Thirty-four sequence types (STs) were identified among the 54 A nidulans complex isolates. A high level of genetic diversity was found among A nidulans sensu stricto strains but low diversity was found among A spinulosporus strains. Amphotericin B showed high MICs to all species. The most active azole was posaconazole (GM = 0.64 mg/L), while itraconazole showed the highest MICs among azoles (GM = 2.95 mg/L). A spinulosporus showed higher MICs than A nidulans sensu stricto for all antifungals except for micafungin and anidulafungin. Interspecies variations may result in differences in antifungal susceptibility patterns and challenge antifungal therapy in infections caused by A nidulans. Differences in the distribution of STs or persistence of multiple STs might be related to the sources of isolation and niche specialisation. © 2019 Blackwell Verlag GmbH
