The Relationship between VDR Gene Polymorphisms Bsm1 and Apa1 with Breast Cancer Risk.

Background In addition to its multifaceted physiological functions, vitamin D is recognized for its protective role against cancer. To manifest its effects, vitamin D engages with the vitamin D receptor ( VDR ) gene responsible for its encoding. Investigations have unveiled that polymorphisms within the VDR gene exert influence over the expression and/or functionality of the VDR protein. Notably, certain VDR gene polymorphisms have emerged as particularly pertinent in the context of tumorigenesis, including Fok1 (rs2228570), Bsm1 (rs1544410), Taq1 (rs771236), and Apa1 (rs7975232). This study aims to scrutinize the correlation between the Bsm1 and Apa1 polymorphisms and the susceptibility to breast cancer development. Materials and Methods In this study, 50 patients suffering from breast cancer with less than 6 months breast cancer diagnosis and 50 healthy control individuals have been chosen. Restriction fragment length polymorphism polymerase chain reaction was used to determine the genotype of polymorphisms. Results The results of the statistical analysis showed that among the studied polymorphisms, there was no correlation with the development of breast cancer. Conclusion Studies on various cancers have produced inconsistent results regarding vitamin D's role in the development and progression of cancer. Therefore, further research is necessary to determine vitamin D's role in cancer development and progression.

The role of serum lipid profile, fasting blood sugar, and body mass index on recurrence and metastasis in patients with estrogen receptor-positive breast cancer: A case-control study.

Background: Breast cancer (BC) is the leading cause of cancer death in women. The current study is designed to evaluate the association of lipid profiles, FBS, and body mass index (BMI) with BC recurrence and metastasis. Materials and Methods: This is a case-control study on estrogen receptor-positive BC patients in Isfahan Province, Central Iran, between 2008 and 2020. The control group was patients who had no evidence of recurrence or metastasis at least 1 year after the end of chemotherapy and hormone therapy. The case group was patients with evidence of metastasis or recurrence within 1 year after the end of chemotherapy and hormone therapy. Fasting blood sugar (FBS), total cholesterol (Chol), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were measured before treatment, after chemotherapy, and after hormone therapy as well as BMI in the case and control groups. Results: There were 108 patients in the case and 119 patients in the control group with a mean age of 50.72 ± 13.26 and 51.91 ± 11.79, respectively. There were no meaningful differences between the case and control groups regarding serum FBS, Chol, TG, HDL, LDL, and BMI. Conclusion: We found no association between serum FBS, lipid profile, and BMI at initial diagnosis and BC recurrence or metastasis.

Efficacy and Safety of Inhalation of Nebulized Ethanol in COVID-19 Treatment: A Randomized Clinical Trial.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a pandemic caused by the SARS-CoV-2 virus. Many efforts have been made and are currently being made to prevent and treat this global disease. OBJECTIVES: This study was designed to evaluate the efficacy and safety of nebulized ethanol (EtOH) in treating COVID-19. METHODS: A randomized clinical trial (RCT) of 99 symptomatic and real-time polymerase chain reaction (RT-PCR)-positive patients admitted to a hospital receiving remdesivir-dexamethasone was conducted. They were randomly assigned to receive distilled water spray (control group (CG)) or 35% EtOH spray (intervention group (IG)). Both groups inhaled three puffs of spray (nebulizer) every six hours for a week. The primary outcome included Global Symptomatic Score (GSS) between the two groups at the first visit and on days three, seven, and 14. Secondary outcomes included the Clinical Status Scale (CSS; a seven-point ordinal scale ranging from death to complete recovery) and readmission rate. RESULTS: A total of 44 and 55 patients were enrolled in the IG and CG, respectively. Although there was no difference at admission, the GSS and CSS improved significantly in the IG (p = 0.016 and p = 0.001, respectively). The IG readmission rate was considerably lower (0% vs. 10.9%; p = 0.02). CONCLUSIONS: Inhaled-nebulized EtOH is effective in rapidly improving the clinical status and reducing further treatment. Due to its low cost, availability, and absent/tolerable adverse events, it could be recommended as an adjunctive treatment for moderate COVID-19. Further research on curative effects in more serious cases and in prevention is advisable.

Complementary and Alternative Medicine in Cancer Patients and the Causes of Tendency to Use Such Treatments in Isfahan, Iran.

Background and Aim: The current study aimed to, first, investigate the frequency of cancer patients who receive complementary and alternative medicine (CAM), separated by the type of the disease, and second, to study their incentives and causes of use. Materials and Methods: Following a cross-sectional design, cancer cases referred to referral centers of cancer in Isfahan province were studied. Data were collected using a researcher-developed checklist that included type of the disease, complementary medicine, and causes of a tendency to use CAM. Results: A total of 256 patients were studied. One hundred and sixty-three patients (63.7%) had a history of receiving CAM. Sixty-five percent of the patients were satisfied with their CAM treatment. Patients with breast cancer had the highest prevalence of CAM use (72.2%), which was more than other types of cancers (P = 0.046). There was no significant association between the frequency of CAM use and the patient characteristics such as age, level of education, marital status, and gender (P > 0.05). Conclusion: It is evident that the majority of patients with cancer are using CAM modulates and are satisfied with it. They want to try every possible way to cure. Physicians should consider the likelihood that their patient is taking CAM and adopt appropriate strategies to address the issue.

Implementation of the Hospital Incident Command System during COVID-19 Pandemic; Experience from an Iranian Reference Hospital.

Introduction: There is growing popularity of the Hospital Incident Command System (HICS) as an organizational tool for hospital management in the COVID-19 pandemic. We specifically describe implementation of HICS at the Isfahan province reference hospital (Isabn-e-Maryam) during the COVID-19 pandemic and try to explore performance of it. Methods: To document the actions taken during the COVID-19 pandemic, standard, open-ended interviews were conducted with individuals occupying activated HICS leadership positions during the event. A checklist based on the job action sheets of the HICS was used for performance assessment. Results: With the onset of the pandemic, hospital director revised ICS structure that adheres to span of better control of COVID-19. Methods of expanding hospital inpatient capacity to enable surge capacity were considered. The highest performance score was in the field of planning. Performance was intermediate in Financial/Administration section and good in other fields. Discussion: In the current COVID-19 pandemic, establishing HICS with some consideration about long-standing events can help improve communication, resource use, staff and patient protection, and maintenance of roles.

Correlation between air pollution and hospitalization due to myocardial infarction.

BACKGROUND: Air pollution is associated with increased risk of cardiovascular disease (CVD). This study aims to evaluate the correlation between air pollutants and hospitalization due to myocardial infarction (MI) as part of "correlation of air pollution with hospitalization and mortality of CVDs and respiratory diseases (CAPACITY) study". METHODS: This case-crossover study analyzed the data of 319 patients who were admitted with diagnosis of ST-elevation MI (STEMI) or non-ST-elevation MI (NSTEMI) in three main hospitals of Isfahan, Iran. The data of airborne pollutants including particulate matter < 10 µm (PM10), particulate matter < 2.5 µm (PM2.5), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and ozone (O3) as well as climatic indices (temperature, wind speed, and humidity) at 24 hours, 48 hours, and one week before admission were extracted from CAPACITY study. The conditional logistic regression method was used to evaluate the correlation between air pollutants and MI hospitalization. RESULTS: 319 patients with mean age of 63.15 ± 28.14 years, including 238 men (74.6%), and 207 patients with STEMI (64.8%) were recruited. The risk of hospitalization significantly increased in patients with STEMI and 10-unit increment in PM2.5 at 48 hours before admission [odds ratio (OR) = 3.70, 95% confidence interval (CI): 1.69-7.69]. Although, majority of air pollutants had positive association with hospitalization in patients with NSTEMI, they were not statistically significant. CONCLUSION: This study showed significant association between elevated PM2.5 at 48 hours before admission and hospitalization of patients with STEMI. This finding can warn policymakers to design better care services for patients at risk of acute MI during the times of increased air pollution.

Association between ambient air pollution and hospitalization caused by atrial fibrillation.

BACKGROUND: Many studies have shown the worst effects of air pollution on cardiovascular diseases (CVDs). Present study focused on the relationship between atrial fibrillation (AF), as one of the common arrhythmias, and air pollutants in Isfahan, Iran, an industrial city in the Middle East. METHODS: A case-crossover design was used to explore the associations between air pollution and AF hospitalized patients with ventricular response (VR) > 90 beats per minute (bpm) (fast response) and those with VR ≤ 90 bpm. All patients' records were extracted from their hospital files. Air pollutants data including particulate matter less than 10 µ (PM10), PM2.5, carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3) were obtained from the Correlation of Air Pollution with Hospitalization and Mortality of Cardiovascular and Respiratory Diseases (CAPACITY) study. Conditional logistic regression test was used to measure the relationship between pollutants and hospitalization due to AF. RESULTS: Records of 369 patients, including 173 men (46.9%) who were hospitalized for AF during the study period and had complete data were extracted. Although a positive but not statistically significant relationship was shown between 10-unit increases in all pollutants (except PM10) and the hospitalization due to AF in patients with rapid VR (RVR), the only significant relationship was observed in case of NO2 [odds ratio (OR) = 1.26, 95% confidence interval (CI) = 1.0-2.1, P = 0.031]. CONCLUSION: This study showed positive significant relationships between NO2 and the hospitalization due to AF in patients with RVR. NO2 is a greenhouse gas whose levels are expected to increase due to global environmental changes. Therefore, relevant strategies should be adopted to decrease its levels, especially in industrial cities like Isfahan.

GJA4/Connexin 37 Mutations Correlate with Secondary Lymphedema Following Surgery in Breast Cancer Patients.

Lymphedema is a condition resulting from mutations in various genes essential for lymphatic development and function, which leads to obstruction of the lymphatic system. Secondary lymphedema is a progressive and incurable condition, most often manifesting after surgery for breast cancer. Although its causation appears complex, various lines of evidence indicate that genetic predisposition may play a role. Previous studies show that mutations in connexin 47 are associated with secondary lymphedema. We have tested the hypothesis that connexin 37 gene mutations in humans are associated with secondary lymphedema following breast cancer surgery. A total of 2211 breast cancer patients were screened and tested for reference single nucleotide polymorphisms (SNPs) of the GJA4 gene (gap junction protein alpha 4 gene). The results presented in this paper indicate that two SNPs in the 3' UTR (the three prime untranslated region) of the GJA4 gene are associated with an increased risk of secondary lymphedema in patients undergoing breast cancer treatment. Our results provide evidence of a novel genetic biomarker for assessing the predisposition to secondary lymphedema in human breast cancer patients. Testing for the condition-associated alleles described here could assist and inform treatment and post-operative care plans of breast cancer patients, with potentially positive outcomes for the management of disease progression.

Air pollution and cardiovascular and respiratory disease: Rationale and methodology of CAPACITY study.

BACKGROUND: Considering the high level of air pollution and its impact on health, we aimed to study the correlation of air pollution with hospitalization and mortality of cardiovascular (CVD) and respiratory diseases (ResD) (CAPACITY) to determine the effects of air pollutants on CVD and ResD hospitalizations and deaths in Isfahan, Iran. METHODS: Hourly levels of air pollutants including particulate matter (PM), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3), information of CVD and ResD admissions and death certificate were obtained respectively from Department of Environment (DOE), Iran, hospitals and cemetery. Time series and case-crossover model were used to find the impact of air pollutants. This paper only summarizes the descriptive findings of the CAPACITY study. RESULTS: The total number of hospitalized patients were 23781 in 2010 and 22485 in 2011. The most frequent cause of hospitalization and death was ischemic heart diseases in both years. While the mean annual levels of O3, CO, and PM10 were lower in 2011 than in 2010, NO2 and SO2 levels higher in 2011. In both years, PM10 was similarly increased during last month of fall, late spring and early summer. In 2011, the PM2.5 and PM10 monthly trend of change were similar. CONCLUSION: The CAPACITY study is one of the few large-scale studies that evaluated the effects of air pollutants on a variety of CVD and ResD in a large city of Iran. This study can provide many findings that could clarify the effects of these pollutants on the incidence and burden of both disease groups.

Health promoting hospitals: a study on educational hospitals of Isfahan, Iran.

BACKGROUND: The current situation of health promotion (HP) services in hospitals of Iran is unclear. The aim of this study was to assess the status of HP in hospitals in Isfahan, Iran. METHODS: This study is a cross-sectional survey in which 9 educational hospitals selected through census sampling. HP self-assessment was used for the data collection. The assessment teams formed, and evidence examined in line with the tools. RESULTS: The results identified five categories of HP activities in the hospitals consisted: patients,staff, environmental, community, and organizational. The mean of total score of HP was 48.8(9.8). In terms of the HP standards scores, 5 hospitals (55.5%) were at the intermediate level;3 hospitals (33.3%) were at the weak level, and 1 hospital (11.1%) was at the good level.About the standards, the highest score was "information and patient interventions" standard 79.8 (13.5), and the lowest was "continuity and cooperation" standard 36.2 (10.8). CONCLUSION: It seems that some of the health promoting hospitals (HPS) duties carried out by hospitals. So, to improve the quality of health services, it seems useful to encourage policymakers and health service managers to create coherent policies and guidelines in HPS.
