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.

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 Feasibility of Practical Training in Minimally Invasive Surgery at Medical School-A Prospective Study on the Pelvitrainer

Background and Objectives: The acquisition of practical skills at medical school is an important part of the multidimensional education program of future physicians. However, medical schools throughout the world have been slow in incorporating practical skills in their curriculum. Therefore, the aims of the present prospective study were (a) to demonstrate the feasibility of such surgical training, (b) to objectify its benefit in medical education, and (c) to investigate the impact of such training on subsequent career choices. Material and Methods: We introduced a two-day laparoscopy course on the pelvitrainer as part of the curriculum of the gynecological internship of fifth year medical students from 2019 to 2020. The results of the students' training were matched to those of surgeons who completed the same curriculum in a professional postgraduate laparoscopy course from 2017 to 2020 in a comparative study design. Additionally, we performed a questionnaire-based evaluation of the impact of the course on medical education and subsequent career choices directly before and after completing the course. Results: A total of 261 medical students and 206 physicians completed the training program. At baseline, the students performed significantly more poorly than physicians in a median of three of four exercises (p < 0.001). However, this evened out in the final runs, during which students performed more poorly than physicians only in one exercise and even better than physicians in one. The general integration of surgical training in medical school curricula was rated very low (12.4% on the VAS, IQR 3-16%) despite the high demand for such training. In the survey, the course was deemed very beneficial for medical education (median VAS 80.7%, IQR 73-98%), but did not appear to influence the students' subsequent career preferences. Conclusions: The acquisition of practical surgical skills during medical school is significantly under-represented in many medical faculties. The benefits of such training, as demonstrated in our study, would improve the education of future physicians.

Inositols in treating polycystic ovary syndrome and non-insulin dependent diabetes mellitus: now and the future

INTRODUCTION

This Expert Opinion covers recent updates in the use of Inositol in polycystic ovary syndrome (PCOS) and type II diabetes and gives support to researchers and clinicians.

AREAS COVERED

This article discusses the role of Myo-Inositol (MI) and D-Chiro-Inositol (DCI) in physiological function, the use of MI in PCOS, the risks of using DCI in reproductive conditions, the 40:1 combination of MI/DCI in PCOS. Furthermore, we discuss the issues of insulin resistance and how α-lactalbumin may increase the intestinal bioavailability of MI. The paper then transitions to talk about the use of inositols in diabetes, including type II diabetes, Gestational Diabetes Mellitus (GDM), and double diabetes. Literature searches were performed with the use of PubMed, Google Scholar, and Web of Science between July and October 2023.

EXPERT OPINION

Inositol therapy has grown in the clinical field of PCOS, with it demonstrating an efficacy like that of metformin. The use of α-lactalbumin has further supported the use of MI, as issues with intestinal bioavailability have been largely overcome. In contrast, the effect of inositol treatment on the different PCOS phenotypes remains an outstanding question. The use of inositols in type II diabetes requires further study despite promising analogous data from GDM.

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.

Molecular Determinants of Uterine Receptivity: Comparison of Successful Implantation, Recurrent Miscarriage, and Recurrent Implantation Failure

Embryo implantation is one of the most remarkable phenomena in human reproduction and is not yet fully understood. Proper endometrial function as well as a dynamic interaction between the endometrium itself and the blastocyst-the so-called embryo-maternal dialog-are necessary for successful implantation. Several physiological and molecular processes are involved in the success of implantation. This review describes estrogen, progesterone and their receptors, as well as the role of the cytokines interleukin (IL)-6, IL-8, leukemia inhibitory factor (LIF), IL-11, IL-1, and the glycoprotein glycodelin in successful implantation, in cases of recurrent implantation failure (RIF) and in cases of recurrent pregnancy loss (RPL). Are there differences at the molecular level underlying RIF or RPL? Since implantation has already taken place in the case of RPL, it is conceivable that different molecular biological baseline situations underlie the respective problems.

Temporal trends of thyroid cancer between 2010 and 2019 in Asian countries by geographical region and SDI, comparison with global data

Objective

This study aims to describe temporal trends of thyroid cancer (ThC) from 2010 to 2019, in Asian countries by geographical region and sociodemographic index, compared with global data.

Method

Annual case data and age-standardized rates (ASRs) of epidemiological indicators of ThC cancer data were collected from the 2019 Global Burden of Disease (GBD) study from 2010 to 2019 in 49 countries and territories in Asia. The relative difference (%) between years was used to show comparative variations of ASRs for the indicators studied. The female/male ratio was calculated by dividing female ASRs by male ASRs. Also, these rates were compared between the age group ≥70 years old and younger age groups.

Results

In 2019, more than 50% of ThC cases and deaths occurred in Asian countries. A total of 53% of ThC patients lived in Asia and more than 60% of the global burden of ThC was imposed on Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALYs number of ThC cancer increased over 1.28-, 1.26-, 1.3-, and 1.2-fold, in Asia, respectively. During this period, the age-standardized incidence rate (ASIR) and the age-standardized prevalence rate (ASPR) of ThC cancer increased by 5% and 8%, respectively, while the age-standardized death rate (ASDR) and the age-standardized DALYs rate (DALYs ASR) of ThC cancer decreased by 6% and 4%, respectively. These trends are different from what happens in other continents. In 2019, age-specific incidence, death, prevalence, and DALY cases of ThC cancer were peaking at 50-54, 75-79, 50-54, and 55-59 years, respectively. In 2019, the highest ASIR and ASPR of ThC cancer was observed in high-income Asia Pacific countries and the highest ASDR and DALYs ASR in Southeast Asia countries. Only high-income Asia Pacific countries experienced a decreasing trend in ASIR and ASPR from 2010 to 2019. ASDR and DALYs ASR have the highest decreasing trend in high-income Asia Pacific. In 2019, among high SDI Asian countries, the Republic of Korea had the highest ASIR and ASPR, and Brunei Darussalam had the highest ASDR and DALYs ASR. The highest ASIR, ASDR, ASPR, and DALY ASR of ThC cancer was found in Lebanon and Malaysia (high-middle SDIs), Vietnam (middle SDIs), and Cambodia and Palestine (low-middle SDIs). Among low SDI Asian countries, Pakistan had the highest ASIR, ASDR, ASPR, and DALY ASR of ThC cancer. All indicators for most countries were higher in women than men.

Conclusion

More than half of the burden of thyroid cancer is imposed on the residents of the Asian continent. Although the incidence and prevalence of this cancer in Asian countries is lower than that of the world, America, and Europe, the highest rate of death from thyroid cancer occurs in Asia and they witness the highest burden of the disease. Therefore, it seems that implementing early detection strategies and increasing access to treatment facilities in Asia is one of the necessities of thyroid cancer control in its residents.

Psychometric properties of Persian version of the infertile women's exposure to violence determination scale (IWEVDS)

To identify violence among infertile women, a specific tool is needed. "Infertile Women's Exposure to Violence Determination Scale" (IWEVDS) is the only specific tool to assess violence against infertile women. The aim of this study was to determine psychometric properties of the Persian version of the IWEVDS. In this methodological study, content validity of the scale was determined following backward, forward translation. To assess the construct validity, confirmatory factor analysis (CFA) was used through Partial Least Squares (PLS). To do so, the Persian version of the IWEVDS was administered to a continuous sample of 310 infertile women referred to a women's hospital in Tehran. The results of the CFA confirmed the model and demonstrated a good fit on the scale. The Goodness of Fit (GOF) index and the Standardised Root Mean Residual (SRMR) with values of 0.42 and 0.056, respectively, indicate the adequacy of the overall model. The reliability of the scale is confirmed by the acceptable values of Cronbach's alpha, composite reliability, communality coefficient and Spearman correlation coefficient. The values of Cronbach's alpha were 0.90 for domains domestic violence, 0.85 for social pressure, 0.86 for punishment, 0.7 for exposure to traditional practices, and 0.87 for exclusion. The results of the study revealed that the Persian version of the IWEVDS is a 28-item scale with good validity and reliability among Iranian infertile women. Therefore, healthcare professionals can use it to evaluate the infertile women's exposure to violence.

Mapping of Iranian midwifery curriculum according to the International Confederation of midwives competencies

BACKGROUND

Evaluating the curriculum based on its success rate in preparing skilled midwives proficient in performing professional skills is a fundamental component of the midwifery education system. This study aimed to evaluate the content, strengths, and weaknesses of the midwifery curriculum in Iran based on the most recent ICM midwifery education standards in all competence areas, as well as to obtain expert feedback on the necessary courses or lessons for the curriculum using the Delphi method.

METHODS

This research was conducted in two phases: comparative analysis and the Delphi method. In the comparative analysis, the curriculum mapping tool was used to compare Iran's midwifery curriculum for bachelor's degrees to the international standards for midwifery education proposed by ICM in 2019 by a four-point Likert scale (adequate- relatively adequate- relatively inadequate- inadequate). Two individuals evaluated the curriculum independently for the presence of theoretical and clinical courses for attaining each relevant competency. In case of disagreement, the opinion of a third person was used. After identifying the academic deficiencies and weaknesses of the curriculum, the Delphi technique was used with the cooperation of the midwifery board members and directors of midwifery groups from across the country to collect feedback about new courses or lessons that need to be incorporated into the curriculum.

RESULTS

After a comparative analysis, 24 out of 315 essential competencies for ICM in the midwifery curriculum were found to be inadequate or relatively inadequate based on the three experts' opinions after reviewing the programmatic courses and lessons in the curriculum. In 79.5% of the knowledge area and 71.6% of the skill area, the curriculum for midwifery in Iran corresponded to ICM essential competencies. After surveying expert members during multiple Delphi rounds, the members agreed to add some lessons to the midwifery curriculum, design a new course, and hold related workshops to cover the competencies identified as inadequate or relatively inadequate in the comparative analysis.

CONCLUSION

The Iranian midwifery curriculum for acquiring 24 items of ICM essential competencies was deemed inadequate or relatively inadequate. Therefore, it seems in addition to revising Iran's midwifery curriculum following ICM competencies, providing midwifery policymakers with infrastructure and additional support to develop and implement effective midwifery training programs is necessary to ensure that midwives are trained and equipped with the necessary competencies for practice.

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.

How do new mothers describe their postpartum sexual quality of life? a qualitative study

BACKGROUND

Sexuality plays a critical role in a woman's postpartum quality of life and also has a strong impact on the quality of her relationship. Given the sparse body of published literature on the subject, we aimed to explore how new mothers explain their postpartum sexual quality of life.

METHOD

A qualitative study was carried out in Iran and Switzerland from December 2018 to March 2019. Focus groups and semi-structured in-depth interviews (IDIs) were conducted with mothers in the first four months after parturition. Mothers who were older than 18 years, were married or in a stable relationship, and experienced a low-risk vaginal birth or cesarean section participated in the study. We used Graneheim and Lundman's approach for analyzing the data. Multiple data collection methods, maximum variation sampling, and peer checks were applied to enhance the rigor of the data.

RESULTS

We achieved data saturation after two focus group discussions (FGDs), 15 IDIs in Iran, and 13 IDIs in Switzerland. We extracted three themes for postpartum sexual quality of life: (a) sexual worldview, (b) interpersonal relationship, and (c) postpartum sex storm. The participants described sexual worldview as "sexual beliefs", "sexual perceptions", and "sexual behaviors". The interpersonal relationship consists of "changes in postpartum interpersonal relationships" and "supportive role of the husbands/partners". The last one, postpartum sex storm, has three categories including "direct changes in sexual life", "indirect changes in sexual life", and "resumption of sexual intercourse". Differences between the two cultures were identified in some subcategories such as "sexual interests", "comparable to the first intercourse in life", "negative sexual behaviors of husbands/partners", "positive sexual behavior of mothers", "helping with child care and housework", and "emotional support".

CONCLUSION

New mothers explained postpartum sexual quality of life as a three-theme phenomenon. Although most results were similar in both cultures, there were some differences. Our study's results suggest that sexual quality of life is a topic that encompasses international as well as cultural aspects.

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.

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.

Dental cleaning behavior and related factors among hemodialysis patients in the West of Iran: A cross-sectional study

OBJECTIVES

Oral health-related behaviors in hemodialysis patients are reduced, potentially leading to adverse consequences. The aim of the present study was to evaluate dental cleaning behavior (DCB) and related factors among hemodialysis patients.

METHODS

This cross-sectional study was carried out in Sanandaj city, in the west of Iran in 2022. Using the census method, 115 hemodialysis patients from the dialysis center of Tohid Hospital were recruited. Data were gathered by a three-section questionnaire. The first section included demographic characteristics, the second section involved variables related to the health belief model (HBM), and the third section assessed stages of DCB change based on the trans-theoretical model. Analysis of data was done by assessing frequency, descriptive and inferential statistics such as t test, correlation coefficient, and regression.

RESULTS

Only 26.1% of participants reported DCB, defined as tooth brushing at least twice daily; 30.4% were in the precontemplation stage, 26.1% in contemplation, and 17.4% in the preparation stage. Perceived self-efficacy was lower among patients who did not perform DCB. The odds of DCB increased with perceived self-efficacy (odds ratio [OR] = 1.51, 95% confidence interval [CI] = 1.19-1.92, p < .05), cues to action (OR = 1.63, 95% CI = 1.03-2.55, p < .05), and decreased with perceived barriers (OR = 0.68, 95% CI = 0.47-0.97, p < .01).

CONCLUSIONS

DCB of patients on hemodialysis requires improvement. Perceived self-efficacy, cues to action, and perceived barriers constructs of the HBM should be considered in interventional programs targeting to increase oral health as well as in future research in the field.

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.

Effects of Corrective Exercises on Work-Related Musculoskeletal Disorders and Quality of Life in Surgical Residents: A Pilot, Quasi-Experimental Study

PURPOSE

Work-related musculoskeletal disorders (WMSDs) are one of the most important reasons for absenteeism, high costs of health care and human injuries; the latter are very common in medical staff. The present study was designed to evaluate the effects of corrective exercises on quality of life and work-related musculoskeletal disorders in surgical residents.

METHODS

In a quasi-experimental study with a one-group pretest-posttest design, we assessed the eligibility of 135 surgical assistants. All recruited participants performed corrective exercises and were followed for 12 months. The primary outcome of the study was any change in the surgical residents' work-related musculoskeletal disorders, which was assessed using the Nordic Musculoskeletal Questionnaire (NMQ) and the Numerical Pain Rating Scale (NPRS) prior to, and 3, 6, and 12 months after intervention. The secondary outcome was any change in the surgical residents' quality of life (QOL) score, which was assessed at baseline, 6 and 12 months after the intervention using the World Health Organization Quality of Life - BREF (WHOQOL-BREF) questionnaire.

RESULTS

One hundred eligible surgical residents were enrolled, of whom 67 (67%) completed the study. At baseline the majority of the participants were female and >30 years of age. Fifty-five percent of them used analgesic drugs. The use of analgesic drugs per week fell by 14.7% from baseline to 12 months; the change was statistically significant (p = 0.042). The effect of corrective exercises on the intensity of pain in the shoulder (p = 0.002), hand/wrist (p = 0.001), upper back (p = 0.03), lower back (p = 0.02) and knee (p = 0.01) was significant. Corrective exercises also led to a significant rise in the quality-of-life score (p < 0.019).

CONCLUSIONS

This study demonstrated the effectiveness of corrective exercises in reducing work-related musculoskeletal disorders and improving quality of life among surgical residents.

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.

Global incidence, mortality, and burden of esophageal cancer, and its correlation with SDI, metabolic risks, fasting plasma glucose, LDL cholesterol, and body mass index: An ecological study

Background and Aims

Esophageal cancer (EC) is one of the most common gastrointestinal malignancies. The geographical variation shows the influence of genetic factors, ethnicity, and distribution of various risk factors. Accurate knowledge of EC epidemiology at the global level will help to develop management strategies. Therefore, the present study was conducted to investigate the global and regional disease burden of EC, including the incidence, mortality, and burden of this cancer in 2019.

Methods

Incidence, mortality, disability-adjusted life years (DALYs), and age-standardized rates (ASRs) associated with EC in 204 countries in different classifications were extracted from the global burden of disease study. After collecting information on metabolic risks, fasting plasma glucose (FPG), low-density lipoprotein (LDL) cholesterol, and body mass index (body mass index), the relationship between age-standardized incidence rate (ASIR), mortality rate, and DALYs with these variables was determined.

Results

In 2019, 534,563 new cases of EC were reported worldwide. The highest ASIR is related to regions with medium sociodemographic index (SDI), and high middle income according to the World Bank, the Asian continent, and the western Pacific region. In 2019, a total of 498,067 deaths from EC were recorded. The highest mortality rate due to ASR is in countries with medium SDI and countries with upper middle income of the World Bank. In 2019, 1,166,017 DALYs were reported due to EC. The ASIR, ASDR, and DALYS ASR of EC showed a significant negative linear correlation with SDI, metabolic risks, high FPG, high LDL cholesterol, and high BMI (p < 0.05).

Conclusions

The results of this study showed significant gender and geographic variation in the incidence, mortality, and burden of EC. It is recommended to design and implement preventive approaches based on known risk factors and improve quality and access to efficient and appropriate treatments.

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.

Unexpected presentation of accessory breast: vulvar accessory breast tissue: a case report

BACKGROUND

The accessory breast is composed of residual glandular mammary tissue that persists after normal embryonic development. The entity is so rare that it is easily neglected in the diagnosis of disease.

CASE PRESENTATION

We report a 24-year-old virgin Persian woman with a left-sided vulvar mass and no pain or discomfort until shortly before her presentation at our department. Ectopic breast tissue in the vulva was diagnosed. We performed wide local resection of the lesion. Pathological investigation of the lesion confirmed the presence of ectopic breast tissue with secretory changes. She had no specific developmental abnormalities and had no relevant family history. She was followed up for 10 months and had recovered fully by this time.

CONCLUSION

Accessory breast tissue should be considered as a diagnosis when a mass is seen along the embryonic milk line, especially if the clinical findings reveal changes in the mass accompanied by changes in sex hormones.

Sexually Transmitted Diseases-An Update and Overview of Current Research

A rise in the rates of sexually transmitted diseases, both worldwide and in Germany, has been observed especially among persons between the ages of 15 and 24 years. Since many infections are devoid of symptoms or cause few symptoms, the diseases are detected late, may spread unchecked, and be transmitted unwittingly. In the event of persistent infection, the effects depend on the pathogen in question. Manifestations vary widely, ranging from pelvic inflammatory disease, most often caused by Chlamydia trachomatis (in Germany nearly 30% of PID) or Neisseria gonorrhoeae (in Germany <2% of PID), to the development of genital warts or cervical dysplasia in cases of infection with the HP virus. Causal treatment does exist in most cases and should always be administered to the sexual partner(s) as well. An infection during pregnancy calls for an individual treatment approach, depending on the pathogen and the week of pregnancy.

Hysterectomy Using Vaginal Natural Orifice Transluminal Endoscopic Surgery Compared with Classic Laparoscopic Hysterectomy: A New Advantageous Approach? A Systematic Review on Surgical Outcomes

INTRODUCTION

Minimally invasive surgery aims to reduce surgical trauma and post-operative morbidity. Natural orifice transluminal endoscopic surgery is a safe and valid surgical option for hysterectomy. The present systematic review aims to compare hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES) with laparoscopic hysterectomy in terms of efficacy, surgical outcomes, complications, and cost.

MATERIALS AND METHODS

This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. It includes randomized controlled trials, controlled clinical trials, prospective or retrospective cohorts, case-control studies, and previous systematic reviews. Inclusion criteria are as follows: female patients undergoing hysterectomy for benign pathologies by vNOTES or laparoscopic hysterectomy. The assessed outcomes were the following: conversion rate, mean uterus weight (g), operative time (mins), hospital stay (days), peri-operative complications, post-operative complications, peri-operative blood loss (mL), blood transfusion needs, post-operative day 1 hemoglobin (Hb) change (g/dL), post-operative pain level (VAS), and cost (USD) in both techniques.

RESULTS

Seven studies were included. vNOTES hysterectomy was not inferior to laparoscopic hysterectomy regarding surgical outcomes, with a shorter operative time, shorter recovery time, less post-operative pain, and fewer post-operative complications. There was no significant difference in the rate of peri-operative complications and no differences in peri-operative blood loss, post-operative day 1 Hb change, and transfusions. Nevertheless, vNOTES hysterectomy was shown to be more expensive than its laparoscopic counterpart.

CONCLUSIONS

While the feasibility and safety of the vNOTES hysterectomy were already established, this review also underlines the noninferiority of this technique when compared to laparoscopic hysterectomy in terms of surgical outcomes. In addition, vNOTES hysterectomy was associated with faster operating time, shorter hospital stay, and better post-operative pain scores compared with laparoscopic hysterectomy.

Temporal trends of tracheal, bronchus, and lung cancer between 2010 and 2019, in Asian countries by geographical region and sociodemographic index, comparison with global data

BACKGROUND

This study aimed to describe the trends in incidence, mortality, and burden of tracheal, bronchial and lung (TBL) cancer in Asia from 2010 through 2019 and compare with global and other continental data.

METHODS

We collected TBL cancer data from the 2019 Global Burden of Disease (GBD) study from 2010 to 2019 in 49 countries and territories in Asia. For all locations, annual case data and age-standardized rates (ASRs) were used to investigate the incidence, prevalence, mortality, and disability-adjusted life-years (DALYs) of TBL from 2010 to 2019. The relative difference (%) between years was used to show comparative variations of ASRs for the indicators studied.

RESULTS

In 2019, more than 55% of TBL cancer cases and deaths occurred in Asian countries. A total of 57% of lung cancer patients lived in Asia and almost 60% of the global burden of lung cancer was imposed on Asian countries. From 2010 to 2019, incidences, deaths, prevalence cases, and DALYs number of TBL cancer increased over 1.34-, 1.31-, 1.31-, and 1.26-fold, in Asia. During this period, the age-standardized incidence rate (ASIR), the age-standardized death rate (ASDR), the age-standardized prevalence rate (ASPR), and the age-standardized DALYs rate (DALYs ASR) of TBL cancer decreased by 1, 3, 4, and 4%, respectively. While at the same time, the decreasing trend of these rates globally and in America and in Europe happened faster. In 2019, age-specific incidence, death, prevalence, and DALY cases of TBL cancer were peaking at 65-74, 70-74, 65-69, and 65-69 years, respectively. In 2019, the highest ASIR, ASDR, and DALYs ASR of TBL cancer was observed in East Asia countries and the highest ASPR in high-income Asia Pacific countries. Central Asia and high-income Asia Pacific countries experienced a decreasing trend in ASIR and ASDR, and the South Asia countries experienced the highest increasing trend from 2010 to 2019. ASPR only decreased in Central Asia, and DALYs ASR only increased in South Asia. In 2019, among high sociodemographic index (SDI) Asian countries, Brunei Darussalam had the highest ASIR, ASDR, and DALYs ASR and the Republic of Korea had the highest ASPR. Among high-middle SDIs, Turkey and Georgia; among middle SDIs, China and Armenia; among low-middle SDIs, Mongolia and the Democratic People's Republic of Korea had the highest ASIR, ASDR, ASPR, and DALY ASR of TBL cancer. Among low SDI Asian countries, Pakistan had the highest ASIR, ASDR, ASPR, and DALY ASR of TBL cancer.

CONCLUSION

Most of the global burden of lung cancer occurs in Asian countries, and the decreasing trend of incidence, death, prevalence, and burden of this cancer in these countries is slower than in other regions. Therefore, the implementation of necessary measures in order to reduce the process of this cancer is considered urgent.

Global, regional and national burden, incidence, and mortality of cervical cancer

AIM

Among gynecological cancers, cervical cancer is the most common cause of cancer-related death in developing countries. This study analyzes the incidence, mortality, and burden of cervical cancer using the Global Burden of Disease (GBD) 2019 study.

MATERIALS AND METHODS

The GBD (2019) data on cervical cancer was extracted from the Global Health Data Exchange (GHDx) query tool. Age-standardized rate (ASR) incidence, deaths, lost years of life (YLLs), years of life with disabilities (YLDs), and adjusted years of life with disabilities (DALYs) of cervical cancer in women were extracted. Data were extracted globally for 204 countries and groups based on a socio-demographic index (SDI), World Health Organization (WHO) regions, continents, World Bank regions, and 22 GBD regions.

RESULTS

The higher standardized age incidence of cervical cancer is in lower SDI countries, Africa, the African region (According to the WHO), and Sub-Saharan Africa (According to GBD regions). The highest deaths of ASR is in countries with low SDI, low-income group, Africa, the African region (According to the World Health Organization), and Sub-Saharan Africa (According to GBD regions). According to SDI classification, the highest DALYs ASR is in low SDI countries, World Bank Low-income countries, African and then American continents, African region, Sub-Saharan Africa, and then Latin America & Caribbean-WB (Based on GBD regions).

CONCLUSION

In 2019, incidence, mortality, and DALYs of cervical cancer mostly affected countries with lower socioeconomic status. Given that cervical cancer is highly preventable, access to screening services and the presence of trained and knowledgeable health care staff can reduce illness, suffering, and death caused by this malignancy. It is recommended to use the national and international potentials to reduce the incidence of this malignancy.

Can human papillomavirus vaccination during pregnancy result in miscarriage and stillbirth? A meta-analysis and systematic review

INTRODUCTION

Contradictory results regarding the safety of human papillomavirus (HPV) vaccination during pregnancy have been obtained, which has cast doubt on the use of this method. This review and meta-analysis were conducted to evaluate the safety of HPV vaccination during pregnancy.

METHODS

Complying with the inclusion and exclusion criteria, we searched Web of Science, Scopus, Medline, EMBASE, PubMed and Google Scholar databases for articles published in the past decade using the following keywords: 'papilloma human virus', 'HPV vaccine', 'pregnancy' and 'safety and prevention'. The minimum report quality of the articles was 16 based on the STROBE checklist.

RESULTS

Seven articles were included in the study, three of which were included in the meta-analysis, and the rest were reviewed systematically. The results of the meta-analysis showed that vaccination against HPV during pregnancy or around this period does not increase the risk of miscarriage (RR=2.01; 95% CI: 0.66-6.13) and stillbirth (RR=2.02: 95% CI: 0.65-6.27). No significant difference between miscarriage and stillbirth was observed in women vaccinated against HPV versus those not vaccinated.

CONCLUSIONS

The study of 1380424 individuals showed that HPV vaccination during pregnancy is better postponed until after this period. However, no significant evidence was found to indicate that vaccination was dangerous and unsafe during pregnancy. Further studies are needed to draw a more definitive conclusion.

Impact of Adenomyosis on Infertile Patients-Therapy Options and Reproductive Outcomes

Adenomyosis is associated with a negative impact on reproductive outcomes. Although adenomyosis is detected more frequently in women of late reproductive age, its impact on pregnancy rates is important because, in today's world, family planning has shifted towards the late reproductive phase of life for many women. Although the diagnostic indications for imaging studies are well-known, we lack strict diagnostic criteria and classification systems concerning the extent of the disease. Selecting the optimal evidence-based treatment option for adenomyosis is difficult because of the paucity of evidence concerning the association between fertility and the degree and composition of adenomyosis. Furthermore, the treatment of infertility might interfere with the treatment of adenomyosis due to the presence of pain. The aim of this review is to analyze the association between adenomyosis and infertility, and describe treatment options to enhance reproductive outcomes. The following aspects will be addressed in detail: (a) prevalence and causes of adenomyosis, (b) diagnostic tools with imaging techniques, (c) clinical symptoms, (d) proposed pathomechanism of adenomyosis and infertility, and (e) different treatment approaches (pharmacological, surgical, others) and their impact on reproductive outcomes.

Diagnosis of Cervical Cancer and Pre-Cancerous Lesions by Artificial Intelligence: A Systematic Review

OBJECTIVE

The likelihood of timely treatment for cervical cancer increases with timely detection of abnormal cervical cells. Automated methods of detecting abnormal cervical cells were established because manual identification requires skilled pathologists and is time consuming and prone to error. The purpose of this systematic review is to evaluate the diagnostic performance of artificial intelligence (AI) technologies for the prediction, screening, and diagnosis of cervical cancer and pre-cancerous lesions.

MATERIALS AND METHODS

Comprehensive searches were performed on three databases: Medline, Web of Science Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan) and Scopus to find papers published until July 2022. Articles that applied any AI technique for the prediction, screening, and diagnosis of cervical cancer were included in the review. No time restriction was applied. Articles were searched, screened, incorporated, and analyzed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.

RESULTS

The primary search yielded 2538 articles. After screening and evaluation of eligibility, 117 studies were incorporated in the review. AI techniques were found to play a significant role in screening systems for pre-cancerous and cancerous cervical lesions. The accuracy of the algorithms in predicting cervical cancer varied from 70% to 100%. AI techniques make a distinction between cancerous and normal Pap smears with 80-100% accuracy. AI is expected to serve as a practical tool for doctors in making accurate clinical diagnoses. The reported sensitivity and specificity of AI in colposcopy for the detection of CIN2+ were 71.9-98.22% and 51.8-96.2%, respectively.

CONCLUSION

The present review highlights the acceptable performance of AI systems in the prediction, screening, or detection of cervical cancer and pre-cancerous lesions, especially when faced with a paucity of specialized centers or medical resources. In combination with human evaluation, AI could serve as a helpful tool in the interpretation of cervical smears or images.

Delayed cervical cancer diagnosis: a systematic review

OBJECTIVE

Cervical cancer (CC) is a preventable women's cancer. Vaccination and routine Pap smear screening have reduced cervical cancer-related mortality by 70-80% in the world. The eradication of CC depends on identifying the disease early and removing barriers to its timely detection. This review study was designed to determine diagnostic delay and factors related to delayed CC diagnosis in the world.

MATERIALS AND METHODS

A comprehensive search was carried out in databases including Medline, Web of Science, Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan), and Scopus for articles published up to December 2021. Publications were included if they reported data on the delayed CC, and factors related to diagnosis of CC in women. There was no time restriction in this review.

RESULTS

In total, 45 articles were entered into the study. In studies, advanced stages of CC (IIB to IV) varied from 10.2% to 87.9% due to delayed diagnosis. A delayed CC diagnosis was reported in 4.3%-89.1% of patients. The median and mean days of delayed diagnosis were 59-210 days and 2.92-10.5 months, respectively. Factors related to delayed CC diagnosis were categorized into three components including patient, medical history, and health system delay. Patient delay included socio-demographic, husband/ partner, and knowledge. Medical history included medical issues, obstetrics, and family history. Health system delays included health facilities and levels of accessibility.

CONCLUSIONS

There is an urgent need to shorten the diagnostic journey of CC patients by addressing all the components of diagnostic delay and developing strategies to modify the factors associated with these delays.

Potential of Lactobacillus acidophilus to modulate cytokine production by peripheral blood monocytes in patients with endometriosis

Background and Objectives: Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. Pe- ripheral blood monocytes cells (PBMCs) may have altered function to some extent in women with endometriosis. Lactoba- cillus acidophilus is a probiotic bacterium within the human bodywith the ability of alleviating many inflammatory diseases. Here, we examined the effect of L. acidophilus on PBMCs of endometriosis patients. Materials and Methods: In this study, peripheral blood samples were obtained from endometriosis patients (n=11) and  non-endometriosis individuals  (n=11).  After  isolation  of  peripheral  blood  mononuclear  cells  with  Ficoll,  cells were cultured in the presence and absence ofphytohemagglutinin. Also, these cells were co-cultured with 1×106  CFU/ ml of L. acidophilus. IL-6 and IL-1 cytokines were measured by ELISA methodand the two groups were evaluated and compared. Results: The results showed that in endometriosis patients, the production of pro-inflammatory cytokines, including IL-1 and IL-6, by PBMC was increasedcompared to non-endometriosis subjects, and stimuli such as PHA intensified this elevation. Also, L. acidophilus increased the levels of pro-inflammatorycytokines including IL-1 and IL-6. However, the production of these cytokines decreased due to the modulatory properties of bacterial cells after 48 h. Conclusion: According to the results of the current study, IL-1 and IL-6 production was significantly increased in PMBCs of endometriosis patientscompared to that of the healthy controls. Also, Lactobacillus acidophilus was considered as an antigenic compound and induced IL-1 and IL-6 production.According to these results, probiotics can be further used for the treatment of endometriosis patients and more investigations are needed to confirm these results.

MicroRNAs Dysregulation as Potential Biomarkers for Early Diagnosis of Endometriosis

Endometriosis is a benign chronic disease in women that is characterized by the presence of active foci of the endometrium or endometrial tissue occurring outside of the uterus. The disease causes disabling symptoms such as pelvic pain and infertility, which negatively affect a patient's quality of life. In addition, endometriosis imposes an immense financial burden on the healthcare system. At present, laparoscopy is the gold standard for diagnosing the disease because other non-invasive diagnostic tests have less accuracy. In addition, other diagnostic tests have low accuracy. Therefore, there is an urgent need for the development of a highly sensitive, more specific, and non-invasive test for the early diagnosis of endometriosis. Numerous researchers have suggested miRNAs as potential biomarkers for endometriosis diagnosis due to their specificity and stability. However, the greatest prognostic force is the determination of several miRNAs, the expression of which varies in a given disease. Despite the identification of several miRNAs, the studies are investigatory in nature, and there is no consensus on them. In the present review, we first provide an introduction to the dysregulation of miRNAs in patients with endometriosis and the potential use of miRNAs as biomarkers in the detection of endometriosis. Then we will describe the role of the mir-200 family in endometriosis. Several studies have shown that the expression of the mir-200 family changes in endometriosis patients, suggesting that they could be used as a diagnostic biomarker and therapeutic target for endometriosis.

Impact of COVID-19 on cancer screening: a global perspective

PURPOSE OF REVIEW

Cancer screening disruption due to COVID-19 may have a significant impact on patients, healthcare practitioners, and healthcare systems. In this present review, we aim to offer a comprehensive view of the effect of the COVID-19 pandemic on cancer screening programs worldwide.

RECENT FINDINGS

The present review comprised 33 publications. During the COVID-19 pandemic, the rates of cancer screening investigations were drastically reduced worldwide. Screening rates plummeted for all types of cancer, all ages, and racial/ethnic groups. Reductions in screening percentages were higher in several underserved racial groups. Cancer screening was suspended for at least 30 days in 13 countries.

SUMMARY

Screenings for all types of cancer fell sharply. In the chain of cancer management, delays in any step are liable to change the outcome of the next step. Further long-term research will be needed to fully comprehend the impact of the pandemic on cancer services and patient outcomes.

Effect of Maternal Diet on Any Necrotizing Enterocolitis in Neonates: A Randomized Double-Blind Study

Background: The etiology of necrotizing enterocolitis (NEC) is controversially discussed. One of the most recently proposed causes of NEC is an allergy to cow's milk protein. This study was designed to evaluate the effect of a maternal diet without bovine protein on the incidence of any NEC in very low birth weight (VLBW) infants. Materials and Methods: A pilot randomized controlled clinical trial was performed at Akbarabadi Hospital, Tehran, Iran, from December 2019 to July 2020, in women with VLBW infants. One hundred twenty mothers with VLBW neonates were randomly assigned to the intervention or the control group (60 in each). In the intervention group, mothers were given a dairy-free diet during the first 14 days after the newborn's onset of feeding. No special diet was given to the control group. The primary outcome of the study was the rate of any NEC in neonates, which was compared between groups. Any NEC was defined as Bell stage I or greater. Results: The minimum and maximum gestational ages were 26 and 33 weeks, respectively. The minimum birth weight of neonates was 700 g. The two groups did not differ significantly in terms of demographic and preinterventional clinical characteristics. Any NEC was reported in 0% and 10% (5/52) of neonates in the intervention and control groups, respectively; the difference was statistically significant (p = 0.028). The NEC symptoms began ∼34 days after birth. Four cases of NEC were classified as Bell stage I, and one was classified as Bell stage II. No statistical association was registered between sex, gestational age, birth weight, and the onset of feeding with the incidence of any NEC. Conclusion: The use of a cow's milk protein-free diet in mothers and exclusive breastfeeding in preterm VLBW infants may reduce the incidence of NEC. We recommend further studies with larger sample sizes in a multicenter setting. The study was registered at the Iranian Registry of Clinical Trials (IRCT20200415047086N1).

The Global Incidence, Mortality, and Burden of Breast Cancer in 2019: Correlation With Smoking, Drinking, and Drug Use

Background

Female breast cancer (FBC) is the most common type of cancer and is associated with a considerable disease burden as well as significant mortality rates. The present study aimed to provide an update on the incidence, mortality, and burden of FBC in 2019, based on the Global Burden of Disease (GBD) Study.

Materials

The incidence, death rate, disability-adjusted life years (DALYs), years of life lost (YLLs), years lived with disability (YLDs), the age-standardized rates (ASR) of FBC in 204 countries, and a variety of classifications, were retrieved from the Global Burden of Disease Study. Data on tobacco use, alcohol consumption, and drug use were collected. The incidence, mortality, and burden of FBC were registered and compared between regions. Associations between age-standardized incidence rates and age-standardized mortality rates of FBC with smoking, drinking, and drug use were determined.

Results

The highest incidence of FBC was observed in countries with a high socioeconomic status such as those of the European continent. Despite the lower incidence of FBC in countries with a low socio-demographic index (SDI), mortality rates secondary to FBC are higher in these countries than in high-income countries. The highest age-standardized mortality rate has been reported in the Eastern Mediterranean Region (EMRO), followed by the African Region (AFRO). The highest age-standardized rates of DALY and YLL per 100,000 population in 2019 were observed in lower-income countries, while the highest ASR of YLD per 100,000 population was reported in high-income countries.

Conclusion

The present GBD-based study provides a comprehensive review of the incidence, mortality, and burden of FBC in 2019. The incidence of FBC is higher in regions with a higher socioeconomic status, whereas mortality rates and DALYs are higher in poorly developed regions. We suggest better screening measures and early detection programs for the latter regions.

Risk factor analysis in women who underwent trial of labor after cesarean section: a multicenter study in xxxxxx

Objective:

Rising caesarean delivery (CD) rates throughout the world are accompanied with high rates of severe maternal complications. The aim of the present study was to analyze the outcome of trial of labor after caesarean section (TOLAC) in a Western population and identify factors associated with the success of vaginal birth after caesarean section (VBAC).

Material and Methods:

A retrospective study was performed at two large obstetric departments in Germany from 2008 to 2018. Women with singleton pregnancies, a history of only one previous CD with a low transverse incision, a viable fetus in cephalic presentation, and gestational age >32 weeks were included in the study. The characteristics and outcome of successful VBAC and failed TOLAC were compared. A subgroup analysis addressed gestational age, interpregnancy interval, fetal macrosomia, body mass index, and maternal age.

Results:

Of 1,546 patients, 62.3% achieved VBAC while 37.7% had a secondary CD. Independent factors associated with the success of TOLAC were a history of vaginal birth in previous pregnancies (p<0.001) and the use of oxytocin (p<0.001), whereas preterm birth between gestational week 32 and 37 signified a higher risk of failed TOLAC (p=0.04). The success of VBAC did not differ significantly for patients older than 40 years of age, those with a shorter interpregnancy interval than 12 months, and fetal macrosomia with birth weight exceeding 4000 grams. Maternal and neonatal outcomes were poorer in women with failed TOLAC.

Conclusion:

Nearly two thirds of women with a history of CD achieve VBAC in Germany. Previous vaginal birth and the augmentation of labor with oxytocin are positively associated with the achievement of VBAC and no major perinatal complications. The decision to have a TOLAC should be encouraged in the majority of patients. Further studies are needed to evaluate the feasibility of TOLAC in preterm delivery.

Sexual Function and Mood Disorders Among Menopausal Women: A Systematic Scoping Review

BACKGROUND

Changes in sex hormones during menopause may have detrimental effects on a woman's sexual function and cause mood disorders. The treatment of both conditions is a challenge in gynecology.

AIM

To review the published literature on sexual function and mood disorders among peri- and postmenopausal women.

METHODS

The review is based on the methodological framework of scoping reviews. We searched electronic databases including Medline (PubMed), Scopus, Embase, and Web of Science (WoS). Publications that reported data about the relationship between sexual function and mood disorders among menopausal women were included in the review. The search was not subject to any limitation in terms of time or method.

OUTCOMES

The main outcome measures used for the review were sexual dysfunction and mood disorders.

RESULTS

We found 106 total records. After a full-text screening we included 19 studies from 1986 to 2020 based on various methodologies; the majority of the studies16 were cross-sectional. Investigations that addressed the symptoms of mood disorders and some domains of sexual function showed a close relationship between sexual dysfunction and mood disorders among menopausal women.

CLINICAL IMPLICATIONS

In clinical practice, it would be appropriate to screen women for at least one mood disorder or sexual dysfunction. If a woman suffers from either, it will be necessary to assess for a further disorder as well.

STRENGTHS & LIMITATIONS

The review was based on a detailed search of the published literature concerning mood disorders and sexual dysfunction among menopausal women compared to women of reproductive age. Despite the clinical importance of the subject, the number of studies eligible for inclusion in the review are rather small. Further investigation of the topic is clearly warranted.

CONCLUSIONS

While the association between sexual dysfunction and mood disorders appears to be bidirectional, future studies will have to investigate the specific mechanisms by which sexual dysfunction could lead to mood disorders (or vice versa). Future studies should specifically address sexual dysfunctions and attitudes of partners, BMI, family support, sleep, and multiparity.

Effect of tumor morcellation in patients with early uterine sarcoma: a multicenter study in Germany

Objective

The use of power morcellation at laparoscopy may worsen survival rates for patients with malignancy. The aim of the present study was to report the outcome of patients with early-stage uterine sarcoma after morcellation or total en-bloc resection, and evaluate potential signs of sarcoma preoperatively.

Material and Methods

This multicenter retrospective study consisted of patients, who underwent surgery for FIGO-stage-1 uterine sarcoma. Twenty-four patients were divided into a non-morcellation group and a morcellation group. Clinical records and the outcomes of patients, including one-, three- and five-year survival rates were reviewed. Preoperative characteristics of patients with sarcoma were compared to those of a control group with uterine myoma (1:4 ratio), matched by age and type of operation.

Results

Obesity was an independent risk factor for uterine myoma. Tumor growth, solitary growth, largest-diameter lesion >8.0 cm, and anechoic areas suggesting necrosis and increased vascularization were significantly more common in the sarcoma group. A large tumor diameter was significantly associated with mortality. Patients in the non-morcellation group had a slightly lower disease-free survival, but poorer overall survival (OS) rates compared to patients in the morcellation group, but neither difference was statistically significant. Patients in the non-morcellation group, who had undergone a re-exploration experienced late recurrence, but no upstaging was evident after the operation.

Conclusion

Preoperative ultrasound characteristics could be useful to distinguish sarcoma from leiomyoma of uterus. Morcellation of a sarcoma may increase abdominal and pelvic recurrence rates, but may not be associated with OS in patients with FIGO-stage-1 disease.

Effect of sex education on sexual function and sexual quality of life in women with endometriosis: A quasi-experimental study

OBJECTIVE

To evaluate the effect of a sex education program on sexual function and sexual quality of life in women with endometriosis.

METHODS

In a quasi-experimental study, women with endometriosis who had undergone laparoscopic surgery were assigned to an intervention group (n = 36) or a control group (n = 36). The intervention group received a sex education program consisting of two sessions a week (90 min each) for two consecutive weeks; the control group received none. Both groups were followed for 12 weeks. Sexual function and sexual quality of life were assessed on the Female Sexual Function Index (FSFI) and the Sexual Quality of life-Female (SQOL-F) questionnaire before the intervention, as well as 8 and 12 weeks after the intervention. Outcomes were analyzed using Student t test, the χ² test, Fisher exact test, and repeated measures analysis of variance.

RESULTS

The mean age of the study participants was 36.9 ± 5.7 years. The two groups did not differ significantly in terms of demographics and pre-intervention clinical characteristics. At the end of the study, sex education reduced female sexual dysfunction by 58.1% in the intervention group. The mean FSFI score increased significantly in the intervention group from pre-intervention to 8 and 12 weeks post-intervention compared with the scores in the control group (P < 0.001).

CONCLUSIONS

Sex education appears to be a promising intervention for reducing sexual dysfunction and improving sexual function and sexual quality of life in women with endometriosis. Future studies should encompass longer periods of follow up to obtain further data on the efficacy of sex education in this setting.

Correlation between Alkaline Phosphatase and Neonatal Jaundice

Background: Hyperbilirubinemia is one of the most common neonatal disorders and one of the risk factors of neurological complications. So this study was conducted to evaluate the correlation between alkaline phosphatase (ALP) and pathological jaundice.

Methods: A case-control was performed on term neonates with and without pathological jaundice who were referred to the Hazrat-e-Ali Asghar Hospital in 2017. In both groups, cases (neonates with pathological jaundice, n=153) and control (neonates with and without pathological jaundice, n=153) levels of alkaline-phosphatase and serum total bilirubin were evaluated with biochemical tests. Moreover, other data were also recorded from their history and clinical examinations. In addition, the severity of jaundice, duration of hospitalization, type of required treatment, and probable complications after the treatment were considered in follow-up. Data were collected by checklist and entered to SPSS v.20. ALP level and its relationship with serum total bilirubin compared between two groups.

Results: Mean level of ALP was 411.3 ± 134.2 U/L in the case group and 338 ± 131.4 U/L in the control group. Serum total bilirubin level was 11.9 mg/dl in the case group and 6.2 mg/dl in the control group. ALP levels in the case group were significantly more than the control group (p=0.001). There was no correlation between ALP and serum total bilirubin level in neonates in the case group (p=0.532). There was no statistically significant relationship between alkaline phosphatase level and gender of neonates, but the relationship of ALP level with types of delivery was statistically significant (p=0.002). There was not a significant relationship between ALP level with hospitalization duration (p=0.371).

Conclusion: The result of this study showed that there is no correlation between ALP levels and pathological jaundice in patients, although this issue needs to be approved by the other studies.

Effect of laparoscopic cystectomy on ovarian reserve in patients with ovarian cyst

OBJECTIVE

This study aimed to evaluate the effect of laparoscopic cystectomy on ovarian reserve in patients with ovarian cysts.

MATERIAL AND METHODS

This prospective study was performed on 113 women with ovarian cysts in a tertiary referral teaching hospital. All patients underwent laparoscopic cystectomy. Serum levels of antimüllerian hormone (AMH) were measured pre-and, 3 months postoperatively. The primary outcome of the study was to assess the effect of laparoscopic cystectomy on ovarian reserve based on alterations in serum AMH levels. The secondary outcome of the present study was to evaluate the impact of the number of cauterizations, size and type of cysts, bilaterality (bilateral or unilateral), age, and body mass index (BMI) on the ovarian reserve after laparoscopic excision.

RESULTS

Laparoscopic cystectomy reduced the serum AMH levels preoperatively (1.32 ± 4.48 ng/ml) to postoperatively (3.2 ± 1.93 ng/ml) and the difference (- 1.28 ng/ml) was statistically different (0.001 >P). There was a negative significant relationship between the number of cauterizations used and postoperative serum AMH levels (p ≤ 0.001). There was a significant relationship between the location (p ≤ 0.01), type of cyst (p ≤ 0.001) and the serum AMH levels reduction.

CONCLUSION

The number of cauterizations used during surgery, the type of cyst, and bilaterality can affect AMH levels that need to be addressed.

Monocyte Count in Preterm Neonates With and Without Necrotizing Enterocolitis

BACKGROUND

Recently, blood monocyte concentration has been introduced as an inventive biomarker for necrotizing enterocolitis (NEC) in low birth weight neonate; therefore, we aimed to examine and compare blood monocyte counts in preterm neonates with and without NEC.

METHODS

A case-control study was conducted on 160 preterm neonates in Tehran during 2017. In this study, medical records and laboratory findings of 80 neonates with NEC (case) and 80 neonates (control), who were randomly chosen from among neonates who had survived NEC, were reviewed and CBC outcomes were compared between the groups.

RESULTS

We compared 80 cases and 80 controls. The mean gestational age in the NEC and control group was 30.78±2.33 and 31.41±2.16 weeks, respectively. The birth weights in the NEC and control group were 1500±488 and 1562±360 g, respectively. The mean age for developing NEC was 14.14±13.9 days. The absolute neutrophil count (ANC) and absolute lymphocyte count (ALC) did not differ statistically significantly between the two groups. The mean absolute white blood cells (WBC) in the NEC and control group were 11368±7957 and 8268±7505, respectively; absolute WBC was significantly different between the two groups (P=0.001). The mean absolute monocyte count (AMC) in the NEC and control group were 262±193 and 518±691, respectively; the difference in absolute WBC was significant between the two groups (P=0.002). Receiver operating characteristic of AMC values showed a diagnostic accuracy of 0.693 (95% CI: 0.612-0.773) for NEC and 0.738 (95% CI: 0.627-0.850) for stage II and III NEC.

CONCLUSION

The result of this study suggest that the concentration of blood monocyte could be an indicator for NEC in the preterm neonate. However, this result should be confirmed by other studies.

Long-term satisfaction of patients after laparoscopic and robotic-assisted hysterectomy

Introduction

Da-Vinci-Xi is the most recent device used in gynecologic robotic surgery. The aim of the present study was to compare the long-term satisfaction of patients who had undergone conventional laparoscopic hysterectomy or robotic assisted laparoscopic hysterectomy using the Da-Vinci-Xi surgical system.

Methods

All hysterectomies performed at the University Hospital of Luebeck from 2018 to 2019 were reviewed. Postoperative outcomes were compared between women who had undergone total hysterectomy with da Vinci Xi (n = 42) or conventional laparoscopy (n = 97). Postoperative outcomes included pain, elimination of complaints after surgery, bladder function, sexual function, satisfaction with the cosmetic outcome, positive experiences after robotic surgery, and satisfaction with the surgeon’s preoperative explanation. Obese patients were evaluated separately in a subgroup analysis.

Results

Both groups had similar baseline characteristics and complication rates. Preoperative complaints subsided after surgery in a little more than 90% of patients. No significant differences were noted between groups in this regard (p = 0.262), or with reference to postoperative pain after one week (p = 0.866) and one month (p = 0.580), stress incontinence (p = 0.343), sexual function (p = 0.766) and the cosmetic outcome of the abdominal incisions (p = 0.273). The majority of patients who had undergone robotic surgery (96.8%) would be willing to undergo the procedure again if necessary. The subgroup analysis of obese patients revealed no significant differences.

Conclusion

The Da-Vinci-Xi device did not improve the long-term surgical satisfaction of normal-weight or obese patients who underwent hysterectomy compared with patients who underwent conventional laparoscopy performed by experienced laparoscopic surgeons.
