Assessment of species distribution and virulence factors of oral fungal carriage among hospitalized patients with COVID-19: a case-control study.

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.

Deciphering resistance mechanisms and novel strategies to overcome drug resistance in ovarian cancer: a comprehensive review.

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.

A multicenter study of severity and prognosis of symptomatic COVID-19 in end-stage renal disease and non-dialysis patients in East of Iran.

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.

Role of NADPH Quinone Reductase 1 (NQO1) Polymorphism in Prevention, Diagnosis, and Treatment of Gastrointestinal Cancers.

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).

Comparison the salivary streptococcus mutans levels between caries-active and caries-free children from Birjand, Iran: A case-control study.

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.

Autophagy-related genes polymorphism in hepatitis B virus-associated hepatocellular carcinoma: A systematic review.

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.

The global incidence, mortality, and burden of uterine cancer in 2019 and correlation with SDI, tobacco, dietary risks, and metabolic risk factors: An ecological study.

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.

COVID-19 pandemic and the prevalence of domestic violence against Iranian married women.

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.

Cancer incidence in Iran in 2016: A study based on the Iranian National Cancer Registry.

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.

The association between MMP-13 rs478927 gene polymorphism and dental caries susceptibility in children with mixed dentition from Birjand, Iran: A case-control study.

Background and Aims: Gene polymorphisms are responsible for at least part of the variation in caries susceptibility despite similar environmental factors. Genes involved in enamel formation like matrix metalloproteinase-13 (MMP-13) may participate in caries process. The aim was to investigate the association between MMP-13 rs478927 polymorphism and caries susceptibility in 6-years-old children from Birjand, Iran. Methods: Six-years old children from Birjand, Iran, participated in this study. The total decayed, missing, and filled teeth were calculated and defined as caries index (CI). Based on this CI, two groups of high-caries (case) and low-caries (control) were taken into account. Saliva samples were collected and DNA was extracted. The allele and genotypes of MMP-13 rs478927 polymorphism were determined by tetra-primer amplification refractory mutation system-polymerase chain reaction (T-ARMS-PCR) method. p Value was significant if p < 0.05. Results: Three hundred sixty-seven children consisted of 186 low-caries children and 181 high-caries children were included in this study. The mean CI was 6.02 ± 0.81. There was no significant association between high and low-caries groups based on socioeconomic status, eating sweet snacks, parents' susceptibility to dental caries, duration of breastfeeding, and the brushing habit (p > 0.05). There wasn't any significant association between genotype distribution of MMP-13 rs478927 polymorphism and CI groups (p = 0.924). This polymorphism was associated with increased caries susceptibility under all genetic models but this effect was not significant (p > 0.05). Conclusion: The MMP-13 rs478927 gene polymorphism was not significantly associated with dental caries susceptibility in Birjandi children with mixed dentition. It is recommended to conduct studies on children of different dentitions to better understand the role of this polymorphism on caries susceptibility in primary and permanent teeth of children.

Effect of coronavirus disease 2019 on diagnosis and treatment of hepatocellular carcinoma: a systematic review.

Aim: Changes in strategies in the coronavirus disease 2019 (COVID-19) crisis and the imposing of restrictions have isolated many vulnerable patients including those with hepatocellular carcinoma (HCC) from routine medical care. This study investigated how the COVID-19 pandemic is affecting the diagnosis and treatment of HCC. Methods: An extensive search was conducted in the PubMed, Scopus, and Web of Science databases by using the appropriate keywords: COVID-19, hepatocellular carcinoma, hepatocellular cancer, and MeSH. Studies in English related to the purpose of the study were included in the analysis, and review studies, case reports, letters to editors, comments, and reports were excluded. The quality of the studies was assessed by the "Adapted Newcastle-Ottawa Quality Assessment Scales" checklist. The Endnote X7 software has been used for managing items. Results: The final qualitative analysis consisted of 27 articles. During the COVID-19 crisis, HCC diagnosis decreased from 20% to 34.13% compared to pre-crisis. The impact of the COVID-19 pandemic on HCC treatment encompasses a wide range of aspects. Generally, delays in treatment for patients with HCC ranged from more than one month for 21.5% of patients in France, to two months for 26% of patients in Italy, up to 30% in Austria, and 66.7% in Asia-Pacific countries. Conclusions: According to the findings, developing and implementing appropriate diagnostic and therapeutic strategies and developing low-cost and high-precision screening programs among high-risk populations seem to be effective in reducing the impact of the COVID-19 pandemic on HCC management.

18F-FDG PET/MRI and 18F-FDG PET/CT for the Management of Gynecological Malignancies: A Comprehensive Review of the Literature.

OBJECTIVE: Positron emission tomography with 2-deoxy-2-[fluorine-18] fluoro- D-glucose integrated with computed tomography (18F-FDG PET/CT) or magnetic resonance imaging (18F-FDG PET/MRI) has emerged as a promising tool for managing various types of cancer. This review study was conducted to investigate the role of 18F- FDG PET/CT and FDG PET/MRI in the management of gynecological malignancies. SEARCH STRATEGY: We searched for relevant articles in the three databases PubMed/MEDLINE, Scopus, and Web of Science. SELECTION CRITERIA: All studies reporting data on the FDG PET/CT and FDG PET MRI in the management of gynecological cancer, performed anywhere in the world and published exclusively in the English language, were included in the present study. DATA COLLECTION AND ANALYSIS: We used the EndNote software (EndNote X8.1, Thomson Reuters) to list the studies and screen them on the basis of the inclusion criteria. Data, including first author, publication year, sample size, clinical application, imaging type, and main result, were extracted and tabulated in Excel. The sensitivity, specificity, and diagnostic accuracy of the modalities were extracted and summarized. MAIN RESULTS: After screening 988 records, 166 studies published between 2004 and 2022 were included, covering various methodologies. Studies were divided into the following five categories: the role of FDG PET/CT and FDG-PET/MRI in the management of: (a) endometrial cancer (n = 30); (b) ovarian cancer (n = 60); (c) cervical cancer (n = 50); (d) vulvar and vagina cancers (n = 12); and (e) gynecological cancers (n = 14). CONCLUSIONS: FDG PET/CT and FDG PET/MRI have demonstrated potential as non-invasive imaging tools for enhancing the management of gynecological malignancies. Nevertheless, certain associated challenges warrant attention.

External Genitalia Myiasis in a 40-Year-Old Woman.

Human myiasis is an infestation produced by fly larvae invading the tissues. We present a case of a 40-year-old virgin woman with vulvar myiasis. She reported at the gynecology clinic with a bloody discharge, severe pain, and swelling of the genital area for six days. Her menstrual history revealed the use of folded clothes. She had no specific gynecological disease. At the examination of the external genitalia, a tender mass measuring 6 cm × 4 cm and an ulcer measuring 1 cm × 1 cm on the surface of the labia majora were found. The patient was hospitalized. Serology, blood, and urine tests were requested; all laboratory tests were normal. The patient was transferred to the operating room (OR) with the diagnosis of necrotizing fasciitis. In the OR, we performed a longitudinal incision on the mass and removed nearly 30 visible maggots. After washing with normal saline, the patient was transferred to the ward without wound suturing. Debridement of the necrotic vulvar mass along with daily washing was performed for 7 days. The wound was sutured on the seventh day at the OR. Antibiotic therapy was continued for 4 days, and the patient was discharged with normal laboratory tests on the eleventh day after admission. We believe that poor sanitary hygiene was the cause of vulvar myiasis in our patient. We conclude that appropriate measures must be taken to reduce the risk of human myiasis, especially in tropical rural regions.

Circulating tumor cells and circulating tumor DNA in breast cancer diagnosis and monitoring.

Liquid biopsy, including both circulating tumor cells and circulating tumor DNA, is becoming more popular as a diagnostic tool in the clinical management of breast cancer. Elevated concentrations of these biomarkers during cancer treatment may be used as markers for cancer progression as well as to understand the mechanisms underlying metastasis and treatment resistance. Thus, these circulating markers serve as tools for cancer assessing and monitoring through a simple, non-invasive blood draw. However, despite several study results currently noting a potential clinical impact of ctDNA mutation tracking, the method is not used clinically in cancer diagnosis among patients and more studies are required to confirm it. This review focuses on understanding circulating tumor biomarkers, especially in breast cancer.

Effect of alcohol consumption on breast cancer: probabilistic bias analysis for adjustment of exposure misclassification bias and confounders.

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.

Current status and temporal trend in incidence, death, and burden of esophageal cancer from 1990-2019.

BACKGROUND: Esophageal cancer (EC) is one of the world's most unknown and deadly cancers. This study aimed to provide updated epidemiological indicators and the recent trend of EC by age group, gender, and geographical region in the world. METHODS: Annual case data and age-standardized rates (ASRs) of epidemiological indicators of EC were collected from the 2019 Global Burden of Disease (GBD) study from 1990 to 2019 in 204 countries and territories based on the sociodemographic index (SDI). Relative difference (%), average annual percentage change (AAPC), and the male/female ratio were calculated. Data are reported in values and 95% confidence interval (CI). RESULTS: EC age-standardized incidence rates (ASIR) decreased by 19%, age-standardized death rates (ASDR) decreased by 25%, and disability-adjusted life-years ASR (DALYs ASR) decreased by 30% from 1990 to 2019. The higher number of EC cases was in men aged 50 to 69 years and in women aged over 70. From 1990 to 2019, Middle SDI countries experienced a decline in the ASIR and ASDR of EC. The High SDI countries had an increasing ASDR trend. In World Bank High-Income countries, the ASIR of EC has remained unchanged and decreased in other regions. The Asia continent has the highest rate of incidence, mortality, and burden of EC and the highest rate of reduction. East Asia, Southern Sub-Saharan Africa, and Eastern Sub-Saharan Africa respectively have the highest ASIR of EC. Central Asia has experienced the greatest decrease in the ASIR and ASDR of EC, the countries of Central Europe had a steady ASIR and High-Income North America had an increasing trend in ASIR and ASDR. The burden of EC shows a decreasing trend worldwide. Central and East Asia regions have the highest rate and the highest increase in the burden of EC. CONCLUSION: Based on great variation in the geographical distribution of epidemiological indicators of EC, investigating the reasons for this diversity requires more studies to be conducted in the field of prevention, distribution of risk factors, and implementation of screening methods with high cost-effectiveness, and access to treatment methods. The provision of regional solutions may be more effective than global strategies.

Diagnostic and Management Performance of ChatGPT in Obstetrics and Gynecology.

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.

Burden of esophageal cancer between 2010 and 2019 in Asian countries by geographical region and sociodemographic index: A comparison with global data.

BACKGROUND: The aim of this study was to describe the trends in incidence, mortality, and burden of esophageal cancer (EC) in Asia from 2010 through 2019 and compare with other global continental data. METHODS: We collected EC data from the 2019 Global Burden of Disease study from 2010 to 2019 in 49 countries and territories in Asia based on the sociodemographic index (SDI). For all locations, annual case data and age-standardized rates (ASRs) were extracted to investigate the EC incidence, prevalence, mortality, and disability-adjusted life-years (DALYs). The ASR relative difference (%) between years and the male/female (M/F) ratio were calculated. Data are reported in values and 95% uncertainty interval (UI). RESULTS: In 2019, more than 70% of EC new cases, deaths, prevalence, and DALYs occurred in Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALY number of EC increased over 1.10-, 1.07-, 1.14-, and 1.03-fold, in Asia. During this period, the age-standardized incidence rate (ASIR), age-standardized death rate (ASDR), age-standardized prevalence rate (ASPR), and age-standardized DALYs rate (DALYs ASR) of EC decreased by 18, 21, 14, and 22%, respectively. The rate of decline in Asia is higher than in the world and other continents. In 2019, age-specific incidence, death, prevalence, and DALY cases of EC cancer peaked at 65-74, 70-74, 65-69, and 65-69 years, respectively. In 2019, the highest ASIR, ASDR, ASPR, and DALYs ASR of EC were observed in East Asian countries, while having the highest decreasing trend. In 2019, among high SDI Asian countries, Taiwan had the highest ASIR, ASPR, and DALYs ASR, and the United Arab Emirates had the highest ASDR. Among high-middle SDIs, Kazakhstan had the highest ASIR, ASPR, ASDR, and DALYs ASR; among middle SDIs, China had the highest ASIR, ASDR, and ASPR, and Viet Nam had the highest DALYs ASR; among low-middle SDIs, Mongolia had the highest ASIR, ASDR, ASPR, and DALY ASR of EC cancer. Among low SDI Asian countries, Pakistan had the highest ASIR and ASPR, and DALY ASR for EC cancer. For four indicators, in most countries, the ratio of men was higher than women, and in some countries, this ratio reached more than 10 times. CONCLUSION: Although the rate of decline in incidence, death, prevalence and burden of EC in Asia was higher than in other areas in the last 10 years, more than 70% of these amounts occur in Asia. Therefore, it appears that adopting appropriate strategies in the field of identifying and controlling modifiable risk factors for EC, implementing screening programs, and timely diagnosis and treatment will help in reducing the burden of this disease in Asian countries.

Total or Subtotal Hysterectomy for the Treatment of Endometriosis: A Review.

OBJECTIVE: The purpose of the review was to evaluate and compare outcomes after total or subtotal hysterectomy in women with endometriosis or adenomyosis. METHODS: We searched four electronic databases: Medline (PubMed), Scopus, Embase, and Web of Science (WoS). The first aim of the study was to compare outcomes after total and subtotal hysterectomy in women with endometriosis, and the second aim was to compare the two procedures in women with adenomyosis. Publications that reported short- and long-term outcomes after total and subtotal hysterectomy were included in the review. The search was not subject to any limitation in terms of time or method. RESULTS: After screening 4948 records, we included 35 studies published from 1988 to 2021; the studies were based on various methodologies. With regard to the first aim of the review, we found 32 eligible studies and divided these into the following four categories: postoperative short- and long-term outcomes, recurrence of endometriosis, quality of life and sexual function, and patient satisfaction after total or subtotal hysterectomy in women with endometriosis. Five investigations were deemed eligible for the second aim of the review. No differences were seen in terms of postoperative short- and long-term outcomes after subtotal or total hysterectomy in women with endometriosis or adenomyosis. CONCLUSIONS: Preservation or removal of the cervix in women with endometriosis or adenomyosis appears to have no effect on short- or long-term outcomes, recurrence of endometriosis, quality of life and sexual function, or patient satisfaction. Nevertheless, we lack randomized blinded controlled trials on these aspects. Such trials will be needed to enhance our comprehension of both surgical approaches.

Appendiceal Endometriosis: A Comprehensive Review of the Literature.

Objective: the purpose of this review was to evaluate the prevalence of appendiceal endometriosis and the safety of concomitant appendectomy in women with endometriosis or pelvic pain. Materials and Methods: We searched the electronic databases Medline (PubMed), Scopus, Embase, and Web of Science (WOS). The search was not subject to any limitation in terms of time or method. The primary research question was: what is the prevalence of appendiceal endometriosis? The secondary research question was: is it safe to perform appendectomy during surgery for endometriosis? Publications that reported data about appendiceal endometriosis or appendectomy in women with endometriosis were reviewed regarding the inclusion criteria. Results: We found 1418 records. After review and screening, we included 75 studies published between 1975 and 2021. With regard to the first question of the review, we found 65 eligible studies and divided these into the following two categories: (a) endometriosis of the appendix presenting as acute appendicitis, and (b) endometriosis of the appendix as an incidental finding in gynecological surgery. Forty-four case reports described appendiceal endometriosis in women who were admitted for the treatment of pain in the right-sided lower abdomen. Endometriosis of the appendix was observed in 2.67% (range, 0.36-23%) of women who were admitted due to acute appendicitis. In addition, appendiceal endometriosis was an incidental finding during gynecological surgery in 7.23% of cases (range, 1-44.3%). With regard to the second question of the review, which was the safety of appendectomy in women with endometriosis or pelvic pain, we found 11 eligible studies. Reviewed cases had no significant intraoperative or follow-up complications during the 12 weeks. Conclusion: Based on the reviewed studies, coincidental appendectomy appears reasonably safe and was associated with no complications in the cases reviewed for the present report.
