Prevalence of COVID-19 anxiety, geriatric anxiety, and related factors among the elderly in Quchan, Iran during the COVID-19 pandemic: a cross-sectional study

BACKGROUND

Anxiety is a prevalent mental disorder among the elderly, leading to discomfort, disability, increased expenses, reduced quality of life, and dysfunction. Consequently, this study was conducted to determine the prevalence of COVID-19 anxiety and geriatric anxiety, along with the factors influencing anxiety, in the elderly population served by urban healthcare centres in Quchan.

METHODS

This cross-sectional study involved 650 elderly individuals aged 60-95 years. The participants were selected using a two-stage cluster sampling method. Data were collected through three questionnaires: the Geriatric Anxiety Inventory (GAI), the Corona Disease Anxiety Scale (CDAS), and a questionnaire on factors contributing to anxiety. Data analysis was performed using simple and multiple regression with IBM SPSS 24.

RESULTS

The prevalence of geriatric anxiety among the elderly was 40.3%, while the prevalence of COVID-19 anxiety (moderate and severe) was 22.8%. Significant relationships were observed between geriatric anxiety and substance abuse, stressful life events, comorbidities, COVID-19 anxiety, financial support, loneliness, walking habits, and sleep patterns (P < 0.05).

CONCLUSION

COVID-19 anxiety and geriatric anxiety are prevalent concerns among the elderly. Factors like substance abuse, stressful life events, COVID-19-related anxiety, comorbidity, living alone, lack of financial support, and poor walking and sleeping habits, which affect anxiety in the elderly, it is essential to address these factors in life planning and provide services through relevant organisations, healthcare teams, and initiatives by the elderly themselves.

Prevalence of non-alcoholic fatty liver and its related factors in Iran: Systematic review and meta-analysis

Non-alcoholic fatty liver disease (NAFLD) is a systemic disorder with a complex multifactorial and heterogeneous pathogenesis and has become the most common cause of chronic liver disease in many countries around the world. Numerous studies in Iran have presented different results on the prevalence and risk factors of NAFLD, in this study, which has been done in a systematic review and meta-analysis, provides a good estimate of the prevalence and risk factors of the disease in Iran. Following the peer review of electronic search strategies (PRESS and the preferred reporting items for systematic reviews and meta-analyses [PRISMA] statement, we searched Web of Science, PubMed, Embase, Scopus, and Persian scientific searcher (Elmnet) from inception to September 19, 2022. In the present study, 71 articles were reviewed for qualitative and meta-analysis. The overall mean prevalence of NAFLD in children studies was 22.4% (95% confidence interval [CI]: 10.9% to 33.9%). The prevalence was notably higher in adult studies 40.5% (95% CI: 35.1% to 46%). In 24 studies, the association between NAFLD and sex was reported, 10 of which showed significant relationships. Out of 46 studies observed that NAFLD prevalence increased significantly with body mass index (BMI). Eight out of 14 studies reported significant associations between FBS and NAFLD in children's studies. Though Iran has a high NAFLD prevalence compared to most areas, and due to the unfavorable situation of risk factors contributing to the NAFLD, it is necessary to take the necessary interventions to control these risk factors and prevent NAFLD.

The effect of aging on the epidemiology of blood transfusions in North Khorasan province, Iran

PURPOSE

Additional knowledge on the epidemiology and recipients of blood transfusions will help health-care managers to estimate the future needs. The study was performed to define the blood transfusion rate based on gender, sex, and clinical features of patients receiving blood products in all hospitals of the North Khorasan province of Iran.

METHODS

Data on blood transfusion implementation were extracted from blood bank documents. The data for all patients who received at least one blood product were collected from March 2018 to March 2019.

RESULTS

Among blood transfused patients, the highest transfusion rate was for packed red blood cells (PRBC) (47.7%). The two other most frequently used products were fresh frizzed plasma (FFP) (27.2%) and platelets (PLT) (21.9%). The patients in the age group of 51-80 years received the majority of PRBCs and FFPs. Patients aged 21-40 and 61-70 yrs had the highest transfusion rates for PLT. Elderly female patients (57.4%) received more blood products than their male counterparts. The highest blood transfusion rates were among patients with neoplasms, anemia, gastrointestinal bleeding, and gastric diseases.

CONCLUSION

The primary Iranian blood recipients were elderly patients. Population aging is associated with an increase in the number of blood recipients and simultaneously declines the blood donors pool. It highlights the need for optimizing the use of blood in hospitals and having better strategies for overcoming the shortage of blood.

Generating the Engineered Form of a Nanobody Against Placenta Growth Factor with High Antiangiogenesis Potential

Antibody engineering is a dynamic field in antibody industry. Over 30% of novel monoclonal antibodies (mAbs) in R&D and clinical trials are engineered forms. Affinity enhancement contributes to the development of new binders that are not only effective in low dose and cost but also improve some drawbacks of antibody production. After previous successful work on in silico affinity maturation of nanobody against placenta growth factor and finding the best engineered nanobodies (Mut2:S31D and Mut4:R45E), according to bioinformatic parameters and molecular dynamics (MD) simulation results, in this study we focused on experimental confirmation of affinity enhancement of a mutant form of nanobody. So, we cloned and expressed two of four mutant forms in pHEN6c vector. Affinity binding was assayed by enzyme-linked immunosorbent assay on purified mutants, with results showing that 10-time enhancement in affinity compared with the native form associated with MD simulation results. We checked the effectiveness of these mutant nanobodies in angiogenesis inhibition by human umbilical vein endothelial cell proliferation and 3D capillary tube formation. EC50 of mut2, mut4, and native in proliferation assay was 110, 140, and 190 ng/mL, respectively, and that in 3D capillary tube formation was 80, 83, and 100 ng/mL. The results of functional studies revealed strong effectiveness of Mut2 followed by Mut4 compared with the native form. Our study confirmed that in silico approach could facilitate development of novel versions of mAb with better characteristics, which could save cost and time.

The Effect of Theory Based Nutritional Education on Fat Intake, Weight and Blood Lipids

INTRODUCTION

Though Nutrition plays a key role in the control of hypertension, it is often forgotten in Iranian patients' diet. In fact, dietary behavior can be regarded as unsatisfactory among Iranian patients. This study was aimed to assess the effectiveness of theory based educational intervention on fat intake, weight, and blood lipids among rural hypertensive patients.

METHODS

This quasi experimental study was conducted on 138 hypertensive patients who had referred to Ardabil rural health centers during 2014. The nutritional education based on DASH and Health Promotion Model (HPM) was treated for six sessions. The pre-test and post-test had intervals of two and six months. Data were analyzed using SPSS-18 and Chi-square, independent-samples t-test, paired-samples t-test and repeated measure ANOVA.

RESULTS

After treating intervention, weight, dietary fat, LDL_C and Total cholesterol, systolic and diastolic blood pressures decreased significantly in the intervention group compared with the control group (p < 0.001). In contrast, HDL_C increased significantly in the intervention group.

CONCLUSION

Educational intervention, provided based on Pender's health promotion model, affecting fat intake, blood lipids, and blood pressure, led to their decrease.

Can theoretical intervention improve hand hygiene behavior among nurses?

Background

Hand washing is the best strategy to prevent known nosocomial infections but the nurses’ hand hygiene is estimated to be poor in Iran.

Objective

This study aimed to determine the effectiveness of BASNEF (Behavior, Attitude, Subjective Norms, and Enabling Factors) model on hand hygiene adherence education.

Methods

This controlled quasi-experimental study was conducted on 70 hemodialysis unit nurses (35 case and 35 control) in the health and educational centers of the University of Medical Sciences of Urmia, Iran. To collect the data, a six-part validated and reliable questionnaire was used. The data were analyzed using SPSS version18, using Wilcoxon, Mann–Whitney, chi-square, and Fisher’s exact tests. The significance level was considered P<0.05.

Results

The mean age was 38.4±8.1 years for the intervention group and 40.2±8.0 years for the control group. There was no significant difference between the two groups for any demographic variables. Also, before the intervention, there was no significant difference between the two groups for any components of the BASNEF model. Post-intervention, the attitude, subjective norms, enabling factors, and intention improved significantly in the intervention group (P<0.001), but hand hygiene behavior did not show any significant change in the intervention group (P=0.16).

Conclusion

Despite the improving attitudes and intention, the intervention had no significant effect on hand hygiene behavior among the studied nurses.
