    Abstract Background: We analyzed the prevalence of active infection with common curable sexually transmitted infections (STIs) including N. gonorrhea, C. trachomatis, T. vaginalis, and T. pallidum, as well as active infection with HPV, herpes simplex virus types I (HSV-1) and II (HSV-2), M. hominis, M. genitalium, C. albicans, and Ureaplasma in 351 Lebanese women.
    Methods: A cross-sectional study, involving 351 sexually active women, 40 years or younger, who were recruited from outpatient Obstetrics and Gynecology clinic attendees between September 2016 and November 2017.
    Results: The prevalence of active infection was low at 0.3% for N. gonorrhea, 0.6% for HSV-2, 2.8% for C. trachomatis, and 2.9% for any curable STIs. Prevalence of active HPV infection was high assessed at 15.7% for high-risk and 12.2% for low-risk genotypes. Furthermore, the prevalence was 2.0% for M. genitalium, 6.8% for ureaplasma, 13.7% for Candida albicans, and 20.5% for M. hominis. No active infections with T. vaginalis, T. pallidum, or HSV-1 were observed. Significant age differences were noted in the prevalence of high-risk and low-risk HPV genotypes, but no such differences were noted in the prevalence of other infections. No appreciable variations were identified in the prevalence of key STIs based on smoking, marital status, or the number of sexual partners.
    Conclusions: The study documented active infection with substantial prevalence for multiple STIs among women attending outpatient gynecology and obstetrics clinics in Lebanon. These findings underscore the importance of strengthening STI surveillance, linkage to care, and prevention interventions in reducing STI incidence among women.

    Abstract Background: An increase in vascular resistance of uterine vessels is associated with intrauterine growth restriction (IUGR). Sildenafil citrate, a phosphodiesterase-5 inhibitor that stabilizes cyclic guanosine monophosphate (cGMP) and increases nitric oxide levels, improves placental perfusion by dilation of spiral arteries and is beneficial in managing IUGR. This study aims to determine the effectiveness of sildenafil citrate in improving perinatal outcomes in IUGR pregnancies.
    Methods: Meta-analysis was performed on data extracted from all studies specific to sildenafil citrate in IUGR management, searching relevant articles on PubMed, Medline, Google Scholar, Embase, and Cochrane databases. Publications identified by the manual search, based on references in reviews, were also included. Dichotomous results were presented as risk ratio (95% confidence interval), while continuous results were expressed as mean difference (MD); samples represented by the random effects model.
    Results: Nine trials were included where the sildenafil citrate effect was compared with a placebo or no intervention. A significant increase in birth weight [SMD (95% CI), 0.69 (0.31, 1.07)] was seen in IUGR pregnancies managed with sildenafil. However, gestational age (SMD (95% CI), 0.44 (-0.05, 0.94], fetal death rate [RR (95% CI), 0.56 (0.17, 1.79)] in IUGR pregnancies was not changed by sildenafil. Neonatal death [RR (95% CI), 0.93 (0.47, 1.86)] and neonatal intensive care unit (NICU) admissions [RR (95% CI), 0.76 (0.50, 1.17)] were not significantly different between sildenafil and control groups.
    Conclusion: Sildenafil citrate increases birth weight and prolonged pregnancies but did not affect stillbirth rate, neonatal death, and NICU admission.
    Trial registration: The study was registered in PROSPERO on September 18, 2021 (CRD42021271992).

    Abstract Background: Kazakhstan is a transcontinental former Soviet Union republic whose present-day population comprises more than 100 ethnic groups. Insofar as Human Leukocyte Antigen (HLA) genotyping is useful for anthropological studies, data on the HLA profile of Kazakhstani Tatars are lacking.
    Objective: We extend our earlier findings on the unique HLA profile of distinct Kazakhstani populations by examining HLA class I and class II loci in Kazakhstani (Volga) Tatar minority population and its relatedness to those of bordering and worldwide communities.
    Methods: HLA class I and class II genotypes of the Kazakhstan Tatar minority were analyzed by PCR-SSP and were compared to neighboring populations using Neighbor-Joining (NJ) trees and standard genetic distances (SGD) analysis.
    Results: In total, 132 HLA alleles were identified in a sample of 103 Kazakhstani Tatars, of which HLA-A*02:01 (20.1 %), -B*07:02 (12.1 %), -C*07:02 (12.7 %), -DRB1*07:01 (18.1 %), and -DQB1*02:01 (19.6 %) were the most frequent. The most frequent two-locus haplotypes were B*07:02 ∼ C*07:02 (10.6 %) B*07:02 ∼ DRB1*15:01 (06.1 %), B*07:02 ∼ DQB1*06:02 (07.1 %), and DRB1*15:01 ∼ DQB1*06:02 (11.6 %).
    Conclusions: Considering historical data, the close relatedness of Kazakhstani Tatars to European Russians (including Russian Tatars) suggests that Kazakhstani Tatars may be Russian Tatars, who originated from the Volga region, following their massive migrations to central Asia.

    Abstract Purpose: This study assesses HPV prevalence and genotype distribution in Lebanon, and identifies differentials in HPV infection, infection with multiple genotypes, and with high-risk genotypes, by sex, age, and year of data collection.
    Methods: Study participants comprised 1042 female and 160 male participants between 2006 and 2018. HPV genotyping was done by PCR and hybridization (2006-2013) or real-time PCR (2013 onwards). Diversity of HPV genotypes across gender, age groups, and years of data collection was tested by applying Shannon Diversity Index.
    Results: The overall HPV prevalence was 44.8% among study participants, and threefold higher in women than men. Single HPV infection was seen in two-third of HPV-positive participants. Women were less likely to be infected with multiple HPV strains, but more likely to be infected with high-risk or mixed-risk HPV genotypes. HPV-16 (11.0%, 9.8%) and HPV-53 (8.5%, 4.9%) were the most prevalent high-risk HPV genotypes in women and men, respectively, while HPV-18 prevalence was 4.9% in men and 3.1% in women, while HPV-59 prevalence was 6.6% in men and 2.1% in women. Samples collected post-2011 from women showed twice higher odds of HPV infection than those collected earlier and were threefold more likely to be infected with multiple HPV strains, and twice more likely to be infected with high-risk genotypes compared to those tested earlier. Women scored higher on Shannon index indicating high diversity in HPV types and frequency, with trend of increased diversity over time. While the odds of HPV infection remained associated with sex and temporal trend in multivariable analysis, odds of having high-risk genotypes was mainly associated with infection with multiple HPV strains.
    Conclusion: Our study showed high diversity in HPV genotypes and an increasing trend of infection with multiple and high-risk genotypes in recent years. Findings underscore the need for effective screening/surveillance and HPV vaccination programs.

    Abstract HLA class I and class II genotypes from 947 Kazakhstani individuals of Russian origin were analyzed for investigating their most likely origin. The results were compared with similar data from other Russians (East and West), and also Worldwide populations, using standard genetic distances, neighbor-joining dendrograms, correspondence and haplotype analysis. Of the five HLA loci analyzed (HLA-A, HLA-C, HLA-B, HLA-DRB1, and HLA-DQB1) genotyped, 216 HLA alleles were identified. The most frequent alleles were A*02:01 (26.5%), B*07:02 (11.1%), C*04:01 (13.5%) and C*06:02 (12.1%), DRB1*07:01 (13.8%) and DRB1*15:01 (12.2%), and DQB1*03:01 (19.7%). Significant linkage disequilibrium was noted between all HLA pairs. DRB1*15:01 ~ DQB1*06:02 (10.5%), B*07:02 ~ C*07:02 (10.0%), B*07:02 ~ DRB1*15:01 (6.3%), and A*01:01 ~ B*08:01 (4.5%) were the most frequent two-locus haplotypes identified. Subsequent analyses showed that Kazakhstani Russians were closely related to West Russia-residing populations (Northwest Slavic, Vologda, Chelyabinsk, Moscow), East Europeans (Belarus Brest, Ukraine, Poland) and Scandinavians (Swedish, Finns), but distinct from East Russia-residing populations (Tuvians, Siberians from Chukotka, Kamchatka, and Ulchi) and East Mediterraneans (Levantines, Turks, North Macedonians, Albanians), and East Asians (Koreans, Japanese, Taiwanese, Mongolians). These results are in accordance with historical data indicating that the Russians of central Asia originate mainly from European Russia during the migratory flow of 18th and 19th centuries.

    Abstract Background: Among the 125 ethnicities and linguistic groups in Kazakhstan, Koreans represent the eighth minority numerically. HLA class I and class II allele frequencies and extended haplotypes were studied for the first time and were compared to related and distant populations worldwide.
    Methods: HLA class I (A, B, C) and class II (DRB1, DQB1) profile was investigated in Kazakhstani Koreans, and were compared to other populations using standard genetic distances (SGD), neighbor-joining dendrograms, correspondence, and haplotype analysis.
    Results: One hundred and thirty-one HLA alleles were identified in Koreans living in Kazakhstan, with A*02:01 (23.08%), B*35:01 (8.24%), C*01:02 (15.38%), DRB1*08:03 (9.89%), and DQB1*03:01 (21.98%) being the most frequent alleles. A*03:01 ∼ B*07:02 (3.85%), B*08:01 ∼ DRB1*03:01 (3.85%), B*07:02 ∼ C*07:02 (7.14%), and DRB1*08:03 ∼ DQB1*06:01 (9.34%) were the most frequent two-locus haplotypes, while A*02:01 ∼ B*18:01 ∼ C*07:01 ∼ DRB1*11:04 ∼ DQB1*03:01 and A*33:03 ∼ B*44:03 ∼ C*14:03 ∼ DRB1*13:02 ∼ DQB1*06:04 (2.2% each) were the most frequent five-locus haplotypes.
    Conclusion: Korean minority in Kazakhstan was closely related to East Asians, including Mongolians (SGD, 0.044), Tuvans (East Siberia; SGD, 0.081), Burayts (Siberia; SGD, 0.094), but distant from East Mediterranean such as Lebanese (SGD, 0.367), Greek (SGD, 0.377), and Saudi (SGD, 0.414), and most Siberians (SGD, 0.473-0.699). This relatedness could be mainly attributed to massive migration of Koryo Saram to Kazakhstan in the 20th century.

    Abstract Among the 125 ethnicities and linguistic groups in Kazakhstan, Koreans represent the eighth minority numerically. HLA class I and class II allele frequencies and extended haplotypes were studied for the first time and were compared to related and distant populations worldwide. HLA class I (A, B, C) and class II (DRB1, DQB1) profile was investigated in Kazakhstani Koreans, and were compared to other populations using standard genetic distances (SGD), neighbor-joining dendrograms, correspondence, and haplotype analysis. One hundred and thirty-one HLA alleles were identified in Koreans living in Kazakhstan, with A*02:01 (23.08%), B*35:01 (8.24%), C*01:02 (15.38%), DRB1*08:03 (9.89%), and DQB1*03:01 (21.98%) being the most frequent alleles. A*03:01 ∼ B*07:02 (3.85%), B*08:01 ∼ DRB1*03:01 (3.85%), B*07:02 ∼ C*07:02 (7.14%), and DRB1*08:03 ∼ DQB1*06:01 (9.34%) were the most frequent two–locus haplotypes, while A*02:01 ∼ B*18:01 ∼ C*07:01 ∼ DRB1*11:04 ∼ DQB1*03:01 and A*33:03 ∼ B*44:03 ∼ C*14:03 ∼ DRB1*13:02 ∼ DQB1*06:04 (2.2% each) were the most frequent five-locus haplotypes. Korean minority in Kazakhstan was closely related to East Asians, including Mongolians (SGD, 0.044), Tuvans (East Siberia; SGD, 0.081), Burayts (Siberia; SGD, 0.094), but distant from East Mediterranean such as Lebanese (SGD, 0.367), Greek (SGD, 0.377), and Saudi (SGD, 0.414), and most Siberians (SGD, 0.473–0.699).

    Abstract The present-day population of Kazakhstan comprises more than 100 ethnic and linguistic groups, of which Ukrainians rates numerically as the fourth, following native Kazakhs, Russians, and Uzbeks. We investigated the HLA profile of Kazakhstani Ukrainians and compared them with those of other populations by applying genetic distances, correspondence analysis, admixture, and haplotype examination. Of the 128 HLA alleles identified, A*02:01 (28.64%), B*07:02 (9.71%), B*13:02 (9.71%), C*06:02 (15.05%), DRB1*07:01 (15.20%), and DQB1*03:01 (24.76%) were the utmost common alleles. The most common 2-locus haplotypes identified were A*02:01 ~ B*13:02 (6.66%), B*13:02 ~ DRB1*07:01 (6.57%), B*13:02 ~ C*06:02 (10.10%), and DRB1*01:01 ~ DQB1*05:01 (12.12%), while A*02:01 ~ B*13:02 ~ C*06:02 ~ DRB1*07:01 ~ DQB1*02:01 were the most frequent five-locus haplotype (4.04%) in Kazakhstani Ukrainians. Comparative analysis revealed that Ukrainians of Kazakhstan are closely related to Eastern Europeans (included Ukrainians), and European Russians, but distant from Asian populations. This supports the historical notion that Kazakhstani Ukrainians originated from Ukraine, following their massive migrations to central Asia in the 18th-20th centuries.

    Abstract Background: Previous studies examined the association of genetic variation in progesterone receptor (PR) gene (PGR) with ovarian cancer, possibly by altering the expression of PR-B isoform, but with mixed outcome.
    Objective: This study evaluated the association of PGR variants with ovarian cancer and associated features.
    Methods: This was a retrospective case-control study, which involved 82 women with ovarian cancer and 95 cancer-free women who served as controls. Genotyping was done by Taqman® SNP genotyping by qRT-PCR. The PGR variants tested were rs471767 (A > G), rs590688 (G > C), and rs10895068 (G > A). Stratification analyses were used for testing the correlation between the PGR variants with ovarian cancer susceptibility according to menstruation status, FIGO classification, pathological grade, and chemotherapy.
    Results: Significantly lower minor allele frequency (MAF) of rs10895068 was seen among ovarian cancer patients, thereby imparting disease protective nature to this variant. Significant association of rs10895068 genotypes with ovarian cancer was seen under the dominant model, but not other genetic models. FIGO classification correlated positively with rs471767 and rs10895068, while rs10895068 correlated positively with lymph node positivity. Three-locus haplotype analysis identified ACA and HCG haplotypes to be negatively associated with the risk of ovarian cancer.
    Conclusions: This report confirms the contribution of PGR variants, specifically the rs10895068 (+331G/A) the etiology of ovarian cancer.

    Abstract Background: Ovarian cancer (OC) is one of the most common gynecologic cancers,with significant morbidity and mortality. The risk of OC is influenced by hormone status, of which sex hormone-binding globulin (SHBG), which influences the serum availability of steroid sex hormones, is implicated in the pathogenesis and evolution of OC. The aim of this study is to evaluate the involvement of common SHBG gene variants in OC susceptibility and evolution.
    Materials: A case control study including 71 OC patients and 74 cancer-free controls, who were genotyped for rs9898876, rs13894, rs1799941 and rs6257 SHBG SNP. Genotyping was done by the allelic discrimination method, using VIC- and FAM-labeled primers.
    Results: The minor allele frequencies of rs9898876, rs13894, rs1799941 and rs6257 SHBG SNP was comparable between OC cases and control women, implying no significant associations of the tested variants and overall OC risk. Taking homozygous wild-type genotype as reference (OR = 1.00), heterozygous rs9898876 (G/T), and minor allele-carrying genotypes [G/T + T/T] were associated with reduced risk of OC. While rs9898876 heterozygosity (G/T) was predictive of OC occurrence, no significant association of the remaining three tested SNPs was noted with altered risk of OC. Irrespective of FIGO staging, the four tested SHBG SNPs were not associated with the clinical progression of OC.
    Conclusions: In conclusion, SHBG rs9898876 is associated with a decreased risk of OC, and thus constitutes a potential diagnostic biomarker of OC.
