Abstract he Covid-19 pandemic has caused many problems in societies and has caused changes in people's lives. Getting out of the normal routine of life will not be without psychological, social and economic effects. Preliminary studies show that the disease of Covid-19 has harmed men more than women. The mortality rate of men infected with Covid-19 is about 60 to 80% higher than that of women. One of the factors in the incidence and severity of Covid-19 complications in men is occupational and biological factors (Estrogen stimulates the immune system) that make men more vulnerable. Men are more exposed to environmental and occupational risk factors than women, and they have more bad habits such as smoking, alcohol, addiction, and occupational stress. Men are more likely to contract Covid-19 due to their employment outside the home and less self-care. Also, men are genetically more exposed to all kinds of diseases than women, and compared to them, they have more mortality and a shorter lifespan. Therefore, implementing a healthy lifestyle and taking timely care is helpful. Women have more general health than men and use more medical services. Most of the jobs at risk are male. Therefore, men are more affected and have more severe symptoms. Compliance with the principles of personal protection in the workplace based on the relevant protocols is very important in this group. Men's health is an issue that strengthens and improves the health of the society's workforce and the development of the country. Studies show that men's life expectancy is lower than women's. The Covid-19 pandemic has affected the mental health of societies, and men were no exception.

Abstract Artificial Intelligence (AI) is rapidly transforming various sectors, and medical education is no exception. This review explores the multifaceted applications of AI in medical education, including its potential benefits, associated risks, and necessary ethical considerations. It synthesizes current research to provide insights into how AI tools, such as personalized learning platforms and AI-driven content generation, can enhance educational outcomes. Additionally, the review addresses the challenges of AI implementation, such as maintaining academic integrity and ensuring data accuracy, and proposes strategies for responsible integration. By examining these aspects, this article aims to guide educators and institutions in effectively leveraging AI to prepare future healthcare professionals for the digital age.

Abstract Facial filler injections have become one of the most common aesthetic procedures globally. Despite their popularity, complications can arise, often due to inadequate pre-procedural dermatological assessment. This systematic review aims to synthesize available literature on dermatological evaluations in individuals seeking facial filler treatments, with an emphasis on practical clinical strategies. The review reveals a significant variation in evaluation protocols, with limited standardized guidelines. Key dermatological factors including skin type, hydration, photodamage, inflammatory conditions, and vascular mapping are often under-evaluated. Recommendations are proposed for a comprehensive yet practical pre-treatment skin assessment protocol to optimize outcomes and reduce complications. Dermal fillers, particularly those based on hyaluronic acid (HA), are widely used in aesthetic dermatology for facial volume restoration, contour enhancement, and wrinkle reduction. Despite their minimally invasive nature, filler injections are not risk-free.

Abstract The present study examined the mechanisms of cardiac remodeling in heart failure with preserved ejection fraction. Heart failure is a condition in which the heart does not pump blood well or does not fill with blood well. As a result, the heart falls behind in its work of moving blood around the body. This condition causes symptoms such as edema (swelling), shortness of breath and fatigue. The ejection fraction, or EF, of the heart measures the ability of the heart to pump oxygen-rich blood throughout the body. In a healthy heart, the ejection fraction is higher. A lower ejection fraction means that the heart is having difficulty meeting the body's needs. The results of the present study showed that heart failure with preserved ejection fraction (HFpEF) is one of the most common types of heart failure, which occurs due to normal left ventricular function in terms of contraction, but impaired filling or relaxation of the heart. It commonly seen in older adults, women, and patients with type 2 diabetes, obesity, hypertension, and kidney disease. As the population ages and the prevalence of chronic diseases increases, the prevalence of HFpEF is also increasing. The results of this study also showed that patients with low ejection fraction (EF) often excluded from rehabilitation programs due to concerns about the possibility of sudden death or other adverse cardiovascular events during exercise sessions. Recent studies have highlighted the fact that cardiac rehabilitation can improve exercise capacity, cardiac function, and health-related quality of life in patients with congestive heart failure.

Abstract The field of facial aesthetic medicine has evolved significantly, with injectable fillers playing a pivotal role in both reconstructive and cosmetic procedures. Recently, hybrid fillers such as Derma Live and Derma Deep have gained attention for their dual properties of volume restoration and biostimulation. This article explores the clinical value of these new-generation fillers, analyzing their composition, indications, safety profile, and outcomes in facial correction. Drawing from existing studies and real-world application, we assess their effectiveness in deep dermal and subdermal applications, particularly in nasolabial folds, malar augmentation, and post-traumatic defects. Hypothetical data from a prospective cohort of 100 patients treated with Derma Live or Derma Deep indicate high patient satisfaction, sustained aesthetic results up to 18 months, and minimal complications. This positions them as a promising alternative to conventional fillers in selected patients. However, precise injection technique and patient selection remain essential due to rare, but significant, risks of delayed nodular reaction. The study emphasizes the importance of clinician experience, dermal assessment, and post-care monitoring in optimizing outcomes with hybrid fillers like Derma Live and Derma Deep.

Abstract Dental caries is one of the most prevalent chronic diseases in childhood, significantly affecting preschool-aged children’s oral health, nutrition, and quality of life. Socioeconomic factors, including family income and residential environment, have been proposed as determinants influencing the prevalence and severity of dental caries. This systematic review aims to synthesize current evidence examining the relationship between preschool children’s dental caries experience and their place of residence (urban vs. rural) and family income levels. A structured literature (37 articles) search was performed using PubMed, Scopus, Web of Science, and Google Scholar databases for studies published from 2010 to 2025. Findings consistently indicate that children from lower-income families and rural areas exhibit higher caries prevalence and severity, reflecting disparities in access to dental care, dietary patterns, and oral hygiene practices. Interventions targeting vulnerable populations, including community-based preventive programs and socioeconomic policy measures, are warranted to reduce oral health inequalities.
