ABSTRACT

PURPOSE: This study was conducted to evaluate the effect of alcohol consumption on breast cancer, adjusting for alcohol consumption misclassification bias and confounders. METHODS: This was a case-control study of 932 women with breast cancer and 1000 healthy control. Using probabilistic bias analysis method, the association between alcohol consumption and breast cancer was adjusted for the misclassification bias of alcohol consumption as well as a minimally sufficient set of adjustment of confounders derived from a causal directed acyclic graph. Population attributable fraction was estimated using the Miettinen's Formula. RESULTS: Based on the conventional logistic regression model, the odds ratio estimate between alcohol consumption and breast cancer was 1.05 (95% CI: 0.57, 1.91). However, the adjusted estimates of odds ratio based on the probabilistic bias analysis ranged from 1.82 to 2.29 for non-differential and from 1.93 to 5.67 for differential misclassification. Population attributable fraction ranged from 1.51 to 2.57% using non-differential bias analysis and 1.54-3.56% based on differential bias analysis. CONCLUSION: A marked measurement error was in self-reported alcohol consumption so after correcting misclassification bias, no evidence against independence between alcohol consumption and breast cancer changed to a substantial positive association.

ABSTRACT

OBJECTIVES: The use of artificial intelligence (AI) in clinical patient management and medical education has been advancing over time. ChatGPT was developed and trained recently, using a large quantity of textual data from the internet. Medical science is expected to be transformed by its use. The present study was conducted to evaluate the diagnostic and management performance of the ChatGPT AI model in obstetrics and gynecology. DESIGN: A cross-sectional study was conducted. PARTICIPANTS/MATERIALS, SETTING, METHODS: This study was conducted in Iran in March 2023. Medical histories and examination results of 30 cases were determined in six areas of obstetrics and gynecology. The cases were presented to a gynecologist and ChatGPT for diagnosis and management. Answers from the gynecologist and ChatGPT were compared, and the diagnostic and management performance of ChatGPT were determined. RESULTS: Ninety percent (27 of 30) of the cases in obstetrics and gynecology were correctly handled by ChatGPT. Its responses were eloquent, informed, and free of a significant number of errors or misinformation. Even when the answers provided by ChatGPT were incorrect, the responses contained a logical explanation about the case as well as information provided in the question stem. LIMITATIONS: The data used in this study were taken from the electronic book and may reflect bias in the diagnosis of ChatGPT. CONCLUSIONS: This is the first evaluation of ChatGPT's performance in diagnosis and management in the field of obstetrics and gynecology. It appears that ChatGPT has potential applications in the practice of medicine and is (currently) free and simple to use. However, several ethical considerations and limitations such as bias, validity, copyright infringement, and plagiarism need to be addressed in future studies.

ABSTRACT

BACKGROUND: Early Marriage (EM) and associated Stressful Life Events (SLEs) and consequences such as psychological and physical well-being issues can lead to suicide and suicide attempts (SA). The study aimed to investigate the risk of suicide and SA among early married people who experienced SLEs. METHODS: A case-control study was conducted based on the registry for suicide in Malekan county in Iran during 2016-18. Cases included 154 SAs and 32 suicides. Simultaneously, 201 outpatients from the emergency department were chosen as controls. Holms and Rahe life event questionnaire was used to assess SLEs. Sub-group analysis (Mantel-Haenszel) by sex and age groups and multiple logistic regression were used to calculate adjusted Odds Ratios (ORs) with 95% Confidence Intervals (CIs) for the association between EM and suicide risk after adjusting for the potential confounders. RESULTS: The proportion (female vs male) of EM among suicides, controls, and SAs was 31.25% (18.7 vs 12.5%), 15.92% (11.9 vs 4.0%), and 13.0% (11.7 vs 1.3%), respectively. In subgroup analyses by sex, EM was associated with an increased risk of suicide in both females and males 2.64 and 2.36 times, respectively. Likewise, subgroup analysis by age groups revealed that EM increased suicide risk in subjects aged 10-15 years, while no association was found for age groups of 26-40 and > 40. After adjusting for the potential confounders, EM (OR: 3.01; 95% CI: 1.15 -7.29), financial problems (OR = 4.50; 95% CI: 1.83 -9.07), and family problems (OR = 2.60; 95% CI: 1.19-9.59), were associated with an increased risk of suicide. However, no association was found between EM, various types of SLEs, and the risk of SA. CONCLUSIONS: We found EM and SLEs were correlated with suicide risk, while no evidence found that EM increased the risk of SA. Progress in reducing EM and addressing its serious consequences can occur by a stronger political commitment and by sharing the experiences and voices of the early married. Our study provided preliminary findings to guide future studies; however, methodological and longitudinal studies are needed to understand and address the effect of EM on suicidal behaviors.

ABSTRACT

Adipose- stem cells (ASCs) have received much attention in the recent years and several articles have investigated the role of these cells on burn wound healing. To understand the outcomes of the ASCs therapy on burn wound healing, a systematic review was performed. This study was conducted by searching in Pubmed, ISI, and Scopus until May 2021. Thirty-six animal studies were included in this study. The findings revealed that although treatment with ASCs somewhat enhanced the healing rate, cultured ASCs on scaffolds or its combination with hydrogels could significantly increase the viability of ASCs and promote rate of healing. However, clinical studies are necessary to gain a better understanding of the role of ASCs in burn wound healing.

ABSTRACT

The role of human papillomavirus (HPV) in the development of oral lesions is controversial. There has been no comprehensive study about HPV prevalence in Iran. This systematic review and meta-analysis were aimed at finding HPV prevalence of oral lesions and normal oral mucosa in Iran. International (PubMed, Web of Science, and Scopus) and national (Iranmedex, Irandoc, and SID) databases were searched systematically until October 2020. Studies that examined the prevalence of HPV in oral lesions by polymerase chain reaction method were included. The heterogeneity of articles was assessed with the Cochran test and I-Square statistics. The prevalence rate of HPV was calculated using a random-effect model. Of 3729 initially searched articles, 29 articles were eligible for inclusion. The overall prevalence of HPV in oral lesions was 21%. The prevalence was the highest in Rasht (50%) city. Lip lesions had the highest HPV prevalence (40%). According to the classification of lesions, the highest prevalence was of precancerous lesions (29%) and the lowest in normal mucosa (8%). Well-differentiated tumors showed a higher prevalence than poorly-differentiated ones. The highest prevalence of HPV was hairy leukoplakia (70%) and the lowest was of pyogenic granuloma (6%). Also, the prevalence was 31% in oral squamous cell carcinoma. There are differences between HPV prevalence according to the geographical area, intraoral location, type of lesion, and grading. As HPV prevalence was fairly high, further attention to vaccination and treatment for HPV in Iran, as a potential risk factor for oral precancerous and cancerous lesions is recommended.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is the third known animal coronavirus, after severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome coronavirus (MERS-CoV). The mean age of the infected patients was estimated to be between 50 and 69 years old. Accordingly, the COVID-19 mortality rate was calculated as 15%. In this regard, the essential component of prevention and planning is knowledge of laboratory and demographic findings among COVID-19 patients; therefore, the present study was conducted to investigate laboratory and demographic findings among these patients worldwide. This systematic review was performed on the articles published in English between January 1, 2019 and May 4, 2020, using MeSH-compliant keywords such as "COVID-19", "Laboratory, coronavirus disease-19 testing", and " demography " in international databases (PubMed, and web of science Scopus). Thereafter, the articles relevant to laboratory and demographic findings among COVID-19 patients were included in the final review. Reviewing the included articles showed changes in the mean lymphocytes count ranged from 0.7 to 39 in hospital or severe cases. Moreover, Leukopenia was not observed in patients with thrombocytopenia. In addition, C-reactive protein (CRP), leukocytes, D-dimer, FDP, FIB, neutrophils, AST, serum creatinine, t-troponin, troponin I, and blood bilirubin levels showed increasing trends in most studies conducted on COVID-19 patients. Notably, the elevated LDH level was more common among children than adults. According to the results of the present study, and by considering the clinical characteristics of COVID-19 patients on the one hand, and considering the changes in laboratory samples such as lymphocytes and other blood markers due to the damaged myocardial, hepatic, and renal tissues on the other hand, it is recommended to confirm the diagnosis of this infection by evaluating the patients' blood samples using other diagnostic methods like lung scan.

ABSTRACT

Background: The COVID-19 epidemic is a newly emerging infectious disease. This study was conducted to design an appropriate psychometric questionnaire of cultural and social characteristics to evaluate beliefs and preventive behaviors toward COVID-19 among the Iranian's population according to change behavior theory as health belief model (HBM). Methods: The study population included all those who had access to social networks and answered the questionnaire voluntarily. The sample size in this study was 350 people. In this cross-sectional study, a questionnaire was designed using scientific sources and based on the health belief model, and its face and content validity was determined by Content Validity Ratio (CVR), and reliability was determined by the internal consistency; Test-retest was applied to examine the internal consistency of the questionnaire. Data were analyzed using SPSS software version 19. Cronbach's alpha and Intra-class Correlation Coefficient (ICC) were used for the assessment of the reliability of data. Results: Initially, the questionnaire was designed based on the literature reviews and expert's opinion in the field of health education with 79 items. After that, 2 of them were deleted and corrected qualitatively by performing the face and content validity of some items. Therefore, finally, a questionnaire with 77 questions was approved. Based on the constructs of the health belief model, the domains of the questionnaire included perceived sensitivity, severity, benefits barrier, self-efficacy, knowledge and behavior.The content validity of the questionnaire was confirmed. The Cronbach's alpha and ICC for each domain were greater than 0.7. Conclusion: The Questionnaire of beliefs and preventive behaviors toward COVID-19 based on HBM is a valid and reliable instrument in the Iranian population that could be used in related research.

ABSTRACT

Colorectal cancer (CRC) is the second most common cause of cancer-related deaths worldwide. Survival rates are among the most important factors in quality control and assessment of treatment protocols. This study was aimed to assess the survival rate of colorectal cancer in Eastern Mediterranean Region Countries. In the present study we comprehensively searched 6 international databases including PubMed/Medline, ProQuest, Scopus, Embase, Web of Knowledge and Google Scholar for published articles until November 2018. The Newcastle-Ottawa Quality Assessment Form for Cohort Studies was applied to evaluate the quality of included studies. The heterogeneity of papers was assessed with the Cochran Test and I-Square statistics. Meta-regression test was performed based on publication year, sample size and Human Development Index (HDI) of each study. Among the total of 1023 titles found in the systematic search, 43 studies were eligible to be included in the present meta-analysis. According to the results, the 1-year, 3-year and 5-year survival rate of patients with Colorectal Cancer was 88.07% (95% CI, 83.22-92.92), 70.67% (95% CI, 66.40-74.93) and, 57.26% (95% CI, 50.43-64.10); respectively. Furthermore, Meta-regressions did not show significant correlations between survival rate and year, sample size or Human Development Index. Survival rates, especially the 5-year survival rate in the EMRO were less than European countries and the USA. Documented and comprehensive evidence-based findings of the present meta-analysis can be used to enhance policies and outcomes of different medical areas including prophylaxis, treatment and health related objectives in colorectal cancer.

ABSTRACT

PURPOSE: No comprehensive study of cancer incidence and mortality exists in Iran. This study aimed to evaluate the incidence, mortality and epidemiological aspects of cancers in our country. METHODS: In this study, information of cancer incidence and mortality in Iran was retrieved from International Cancer Registry data and reported by numbers, crude and standardized incidence and mortality rates. Cancer incidence and mortality in Iran were mapped and compared with neighboring countries and the world. RESULTS: A total of 84,829 cancer cases occurred in Iran in 2012. Overall, 39,991 cases (47.14%) were women and 44,838 (52.85%) men with male to female ratio 1.12. There were 53,350 deaths, of which 43.55% in women and 56.44% in men. The sex ratio of mortality was 1.29. Five cancers with the highest standardized incidence rates (SIR) were breast cancer (28.1), gastric cancer (15.2), prostate cancer (12.6), colorectal cancer (11.1), and esophageal cancer (8.6). Five cancers with the highest standardized mortality rates (SMR) were gastric cancer (12.9), breast cancer (9.9), esophageal cancer (7.8), lung cancer (6.9) and colorectal cancer (6.6). CONCLUSION: Our findings revealed that the incidence of some cancers increased compared to reports in previous years. The incidence and mortality were higher in men than in women. Common cancers should be detected early using screening tests such as colonoscopy and mammography. The tests can be especially useful in old age. Additional studies should be performed to investigate the causes of cancer incidence and mortality.

ABSTRACT

BACKGROUND: Cancer is the second leading cause of death in developing countries. In Iran, cancer is the third cause of death. The present study aimed at providing the incidence rates (crude and agestandardized) of different types of cancers in Sistan and Baluchestan province (Southeastern of Iran). METHODS: Data were collected retrospectively reviewing all new cancer patients registered in Cancer Registry Center of Health Heputy for Sistan and Baluchestan province. Common cancers were defined based on the number of cases and standardized incidence rates. To compute the annual percentage change (APC), joinpoint 4.1.1.1 software was applied. RESULTS: A total of 3535 cases of cancers registered during 2004-2009 were identified. Of these, 46.82% occurred in females and 53.18% in males. The most frequent cancer in women was breast cancer followed by esophagus, skin, colorectal and leukemia. The 5 most frequent cancers in men were stomach, skin, leukemia, esophagus and bladder. Joinpoint analyze showed a significant increasing trend for adjusted standard incidence rate (ASIR) for both sexes (p<0.05). CONCLUSION: According to The results of the present study and comparison to previous studies for other provinces in Iran, cancer incidence in Sistan and Baluchistan is less common but trends of cancers are increasing in Sistan and Baluchestan Province. It is necessary to have a comprehensive health policy for prevention and control of this problem.

ABSTRACT

Objective: Dental plaque bacteria, including Streptococcus mutans (SM), play a role in the pathogenesis of the dental caries. There are conflicting results regarding the association of salivary SM level and dental caries susceptibility. Our aim was to compare salivary SM levels in colony-forming units (CFU) between children with active caries and caries-free children in Birjand, Iran. Methods: This case-control study included 61 six-year-old children referred to health centers in Birjand city, Iran, in 2022. The children were divided into two groups: case (dmft/DMFT>0 with active caries) (including 31 children) and control (dmft/DMFT = 0 [caries-free]) (including 30 children). Demographic information and dental history were recorded. Oral examinations were also performed by the dentist. Unstimulated saliva samples were collected from children. The number of salivary SM colonies was determined using the microbial culture and confirmed using the polymerase chain reaction (PCR). The data were analyzed using Chi-square and T-tests at a significance level of p < 0.05. Results: The mean number of SM colonies was 126.24 ± 92.78 CFU/ml and 92.38 ± 75.34 CFU/ml in case and control groups, respectively. No significant difference was found in salivary SM levels between case and control groups (P = 0.125). No significant association was observed between caries experience with gender (P = 0.363), type of school (public/private) (P = 0.296), receiving oral health education (P = 0.072) and frequency of tooth brushing (P = 0.935). The mean gingival index (P = 0.001) and plaque index (P = 0.025) in case group were significantly higher than control group. Conclusion: There is no significant difference in salivary SM levels between caries-active and caries-free children in Birjandi children.

ABSTRACT

Background and Aim: Endometrial cancer (EC) is the sixth most common cancer among women worldwide. Since global studies are based on awareness of the incidence trend, mortality, geographical diversity, and level of social development and income of countries, this study was conducted to investigate the trend of uterine cancer (UC) in the world in 2019. Methods: Age-standardized rates (ASR) of incidence, deaths, prevalence, and disability-adjusted life years (DALYs) of UC, as well as targeted risk factors, were extracted from the Global Burden of Disease (GBD) online database 2019. Pearson correlation coefficient and SPSS 16 were used to calculate the correlation between risk factors and ASR of epidemiological indicators. Statistical significance was considered as p < 0.05. Results: In 2019, the age-specific incidence and death rate of UC was peaking at 60-64 and 65-69 years, respectively. The highest age-standardized incidence rate per 100,000 people for UC has been reported in the Northern Mariana Islands, high sociodemographic index (SDI) countries, World Bank High-Income category, Europe continent and among World Health Organization (WHO) regions were found in the European Region. The highest age-standardized death rate per 100,000 people for UC has been reported in Grenada, high SDI countries, the World Bank High-Income category, Europe continent, and among WHO regions found in the European Region. In 2019, the age-standardized DALYs rate was 53.54 per 100,000 inhabitants, of which 48.49 cases were related to years of life lost (YLLs) and 5.05 cases were related to years lived with disability. Conclusion: According to GBD-2019, the highest incidence, mortality, and DALY of UC are in Europe. The evidence and traces of diversity can be seen in the inequalities of UC. Race, ethnicity, economic status, level of education and awareness, co-morbidities, access, grade, and histological type of tumor are the most important causes of this inequality.

ABSTRACT

OBJECTIVES: This study aimed to assess the severity and related factors of symptomatic COVID-19 in end-stage renal disease (ESRD) patients from several centers in Eastern Iran. METHODS: In this retrospective cohort study, after obtaining ethical approval, 410 patients diagnosed with COVID-19 were included for analysis. Patients were categorized into two groups based on their dialysis status: the dialysis group (ESRD patients undergoing hemodialysis) and the non-dialysis group (those without chronic dialysis). Demographic information, clinical symptoms, laboratory tests at admission, length of hospitalization, ICU admission, need for mechanical ventilation, and mortality data were extracted from their medical records and entered into researcher-developed checklists. RESULTS: In this multicenter study, 104 dialysis patients with a mean age of 64.81 ± 16.04 were compared to 316 non-dialysis patients with a mean age of 60.92 ± 17.89. Patients were similar in terms of age and gender, but a higher percentage of the dialysis group was aged over 65 years (p = .008). Altered consciousness, dyspnea, headache, myalgia, anorexia, and cough were statistically significantly more common in the dialysis group when evaluating clinical symptoms (p < .05). The dialysis group had significantly higher levels of white blood cell (WBC), potassium, calcium, urea, creatinine, blood pH, INR, ALT, ESR, and CRP, and lower levels of red blood cell, Hb, platelets, sodium, and LDH compared to the non-dialysis group. Profoundly altered consciousness was more common among deceased patients (p < .001), and this group had higher WBC counts, urea levels, AST, ALT (p < .05), and lower blood pH (p = .001). CONCLUSION: Based on the results of this study, it is plausible to suggest a hypothesis of greater severity and worse prognosis of COVID-19 in ESRD patients. Underlying comorbidities, such as liver disorders or more severe clinical symptoms like altered consciousness, may also be indicative of a worse prognosis in dialysis patients with COVID-19.

ABSTRACT

Most cancer deaths are related to gastrointestinal (GI) cancers. Several environmental and genetic factors are effective in the occurrence of GI cancers, such as esophageal, stomach, colorectal, liver, and pancreatic cancers. In addition to risk factors related to lifestyle, reactive oxygen species (ROS) also play a role in GI cancers, and an increase in the amount of free radicals can lead to oxidative stress and increase the probability of malignancies. NQO1 is part of the body's antioxidant defense system that protects cells against mutagenesis and carcinogenesis. NQO1 is responsible for reducing quinones to hydroquinone and preventing the generation of ROS by catalyzing the reaction. The existence of single nucleotide polymorphisms (SNPs) of NADPH Quinone Reductase 1 (NQO1), such as 609C>T NQO1, leads to a decrease in NQO1 enzyme activity. Some NQO1 polymorphisms may increase the risk of gastrointestinal cancer. So, the C609T polymorphism in the NQO1 gene has been found to be effective in causing gastrointestinal cancers. On the other hand, it is very important to know the role of biomarkers in the prognosis and management of cancer treatment. Therefore, this study investigated the role of NQO1 as a biomarker in the management of gastrointestinal cancers (prevention, diagnosis and treatment).

ABSTRACT

BACKGROUND: Chronic hepatitis B (CHB) virus is the most common risk factor for developing liver malignancy. Autophagy is an essential element in human cell maintenance. Several studies have demonstrated that autophagy plays a vital role in liver cancer at different stages. In this systematic review, we intend to investigate the role of polymorphism and mutations of autophagy-related genes (ATGs) in the pathogenesis and carcinogenesis of the hepatitis B virus (HBV). MATERIALS AND METHODS: The search was conducted in online databases (Web of Science, PubMed, and Scopus) using Viruses, Infections, Polymorphism, Autophagy, and ATG. The study was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. RESULTS: The primary search results led to 422 studies. By screening and eligibility evaluation, only four studies were relevant. The most important polymorphisms in hepatocellular carcinoma were rs2241880 in ATG16L1, rs77859116, rs510432, and rs548234 in ATG5. Furthermore, some polymorphisms are associated with an increased risk of HBV infection including, rs2241880 in ATG16L1 and rs6568431 in ATG5. CONCLUSION: The current study highlights the importance of rs2241880 in ATG16L1 and rs77859116, rs510432, and rs548234 in ATG5 for HBV-induced HCC. Additionally, some mutations in ATG16L1 and ATG5 were important in risk of HBV infection. The study highlights the gap of knowledge in the field of ATG polymorphisms in HBV infection and HBV-induced HCC.

ABSTRACT

Ovarian cancer is among the most lethal gynecological cancers, primarily due to the lack of specific symptoms leading to an advanced-stage diagnosis and resistance to chemotherapy. Drug resistance (DR) poses the most significant challenge in treating patients with existing drugs. The Food and Drug Administration (FDA) has recently approved three new therapeutic drugs, including two poly (ADP-ribose) polymerase (PARP) inhibitors (olaparib and niraparib) and one vascular endothelial growth factor (VEGF) inhibitor (bevacizumab) for maintenance therapy. However, resistance to these new drugs has emerged. Therefore, understanding the mechanisms of DR and exploring new approaches to overcome them is crucial for effective management. In this review, we summarize the major molecular mechanisms of DR and discuss novel strategies to combat DR.

ABSTRACT

BACKGROUND: Cancer poses an escalating public health challenge, necessitating a comprehensive understanding of cancer incidence to formulate effective control strategies. AIMS: This study aims to present a comprehensive overview of cancer incidence in Iran, utilizing data from the Iranian National Population-based Cancer Registry (INPCR) for the year 2016. METHODS: The study employed INPCR data to compute crude and age-standardized incidence rates (ASR) per 100 000 for the most common cancers among men and women across Iran's 31 provinces. Data analysis utilized Excel (2019) and STATA 14. RESULTS: In 2016, 124 833 new cancer cases were registered, with 65 495 (52.90%) occurring in men and 58 312 (47.10%) in women. ASRs for all cancers in the total population were 177.48, with specific rates for men and women at 192.96 and 162.33, respectively. The five most common cancers in men were prostate (23.25), stomach (21.56), colon (19.30), bladder (16.20), and lung (13.15). Among women, the leading cancers were breast (40.60), colon (14.64), thyroid (10.84), stomach (10.25), and lung (5.63). West Azarbaijan had the highest incidence among men, while Yazd topped the list for women. Age-specific incidence rates revealed peaks in the 67-74 age group for men and the 40-50 age group for women. CONCLUSION: This study affirms that while Iran exhibits a lower cancer incidence compared to global averages, there has been a temporal increase. Disparities in ASR exist across sexes and provinces, with shifts in the ranking of common cancers by sex compared to previous reports.

ABSTRACT

AIM: Domestic violence is an important public health and human rights problem. In most countries of the world, including Iran, the COVID-19 pandemic made quarantine necessary to reduce the disease transmission rate. Therefore, due to the spread of the COVID-19 disease and the emergence of mandatory quarantine conditions, the present study was conducted to determine the prevalence of domestic violence against women during the COVID-19 pandemic in Iran. METHODS: In this cross-sectional study, which was done in 2020, 240 married women were investigated. Due to the COVID-19 pandemic, data collection was performed through virtual networks using standard questionnaires. Data were analyzed using SPSS. Descriptive statistics (relative frequencies, mean, and standard deviation) were used to determine the extent of violence. Independent t-test and Chi-square were used to analyze the data of the relation between the types of violence with independent variables. Also, the data were analyzed using the logistic regression model. RESULTS: In this study, 240 married women with a mean age of 36.27 were studied. The highest frequency was related to social violence (56.3%), and the lowest was related to financial and verbal violence (11.7%). In addition, a significant relationship was observed between sexual violence and age (p-value < 0.05). A significant relationship was also observed between social violence and education [(OR = 1.99)] Jobs [(OR = 2.4, CI = 95%, 1.30-4.4), quarantine duration [(OR = 1.94, CI = 95%, 0.98-3.7)] and underlying diseases [OR = 1.90]. CONCLUSION: The high prevalence of domestic violence against women during quarantine indicates the poor health of women in society. Therefore, the roots of violence against women and methods to reduce this problem should be sought. Therefore, identification of subjects at risk and raising women's knowledge may be useful for the prevention of domestic violence and its physical and psychological complications.

ABSTRACT

Background: The COVID-19 pandemic highlighted the need to study oral fungal carriage and its potential impact. In oral fungal environments, factors like changes in respiratory epithelium, increased pathogen attachment, local inflammation, and virulence factors could influence COVID-19 severity. The authors conducted a study to explore oral fungal carriage in COVID-19 patients and compare it to a healthy control group. Methods: The authors executed a case-control investigation including 144 COVID-19 patients and an equivalent number of 144 healthy controls. The matching criteria encompassed age, sex, body mass index, and the history of antibiotic and antiviral medication intake. This research was performed over a span of 12 months from May 2021 to May 2022. The mouth area was sampled with a cotton-tipped swab. Subsequently, all the samples underwent fungal culture and PCR-sequencing procedures. Results: In COVID-19 patients, oral fungal carriage was three times higher compared to healthy controls. Candida was the exclusive genus found in both groups, with Candida albicans being the most frequently isolated species (90.79%). Among COVID-19 patients, Candida species showed significantly higher esterase, proteinase, and hemolysin activity compared to healthy individuals. Both groups exhibited elevated levels of C. albicans virulence factors compared to non-albicans species. Conclusions: It is crucial to understand the way that virulence factors of oral fungal carriage act in COVID-19 patients in order to come up with novel antifungal medications, identify the contributing factors to drug resistance, and manage clinical outcomes.
