The estimated sample size was 48, determined using a diagnostic test formula. The sample population consisted of female patients with positive VIA or abnormal Pap smear results. Each patient underwent HPV DNA self-sampling and clinician sampling tests using the GenoFlow HPV Array technique and continued with colposcopy. All patients were also administered a questionnaire consisting of eight questions about their perspective on the self-sampling HPV DNA test. The data analysis employed a 2 × 2 table using SPSS version 20, and Cohen’s kappa coefficient was calculated to measure the agreement between the sampling results of patients’ and Clinicians’. \u0000Results: Among the examinations conducted by clinicians, there were 33 patients with positive HPV results, whereas through self-sampling, there were 28 patients with positive HPV (p=0.00). High risk HPV was the most commonly observed, with HPV type 16 appearing the most (15%). Based on these data, the self-sampling sensitivity, specificity, positive predictive value, and negative predictive value were 85%, 100%, 100%, and 75%, respectively, with a concordance rate of 89.6%. The Cohen’s Kappa coefficient between samples taken by the clinician and self-sampling resulted in K=0.778, which is considered a good agreement (K=0.61-0.80). All patients concluded that the procedure was easy (100%), and the majority (60.5%) expressed a preference for the self-sampling method. \u0000Conclusion:  There is a good agreement between the results of self-sampling and clinician sampling for detecting HPV DNA, with patients positively accepting the self-sampling method, indicating its potential as an effective cervical cancer screening method. \u0000Keywords: Cervical Cancer Screening, Clinician Sampling, Human Papillomavirus, Self-Sampling.","PeriodicalId":13477,"journal":{"name":"Indonesian Journal of Obstetrics and Gynecology","volume":"22 24","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141118077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

She was sexually active, used no contraceptives, and had a history of miscarriage. On examination, she was hemodynamically stable. A bimanual exam revealed cervical motion tenderness and pain. A high human chorionic gonadotropin (hCG) level (1,725 IU/L) and a left-sided mass, highly suspected as an extrauterine gestational sac without sign of free fluid in the abdomen nor fetal heart rate on ultrasound, prompted diagnostic laparoscopy.

There were 24 samples with positive HPV DNA before LLETZ/LEEP. Samples then checked for HPV DNA after LLETZ/LEEP. The effectiveness of LLETZ/LEEP therapy was analyzed using the Mc Nemar test. Comparison of HPV DNA outcomes (positive or negative) based on procedure, HPV DNA type and histopathological type was analyzed using Fisher Exact and Pearson Chi Square tests. All data were analyzed using SPPS version 22.0. \u0000Results: In this study, it was found that the average age of patients with cervical precancerous lesions was 40.25 ± 7.67 years (28 - 57 years). Based on the diagnosis, 8 samples were found with High-grade Squamous Intraepithelial Lesion (HGSIL) and 16 samples with Low-grade Squamous Intraepithelial Lesion (LGSIL). All samples in this study were housewives and the majority were multiparas (75.0%). History of abortion in the patients in this study was only found in 5 samples (20.8%). The results showed that there were significant differences in the HPV DNA before and after LLETZ/LEEP therapy (p = 0.000). In addition, the results showed that there was no difference in the outcome of HPV DNA based on the procedure (p = 1.000) and the type of HPV DNA (p = 0.643).

The most common cause of VVC in pregnancy is Candida albicans. During pregnancy, physiological changes occur, such as increased levels of estrogen, lower vaginal pH, increased production of vaginal mucosal glycogen and immunological changes so that Candida colonization in the vagina increases. Increased colonization can be symptomatic or asymptomatic. When symptoms and signs of vulvar pruritus, pain, swelling, redness, burning, dyspareunia, dysuria, vulvar edema, fissures, excoriation and vaginal discharge are found, it is necessary to perform microscopic examination and/or fungal culture to establish the diagnosis of VVC. Topical intravaginal antifungal therapy such as clotrimazole and nystatin, are the recommended treatment for VVC in pregnancy that has been shown its safety. Treatment with oral antifungal is not recommended because of the risk of causing congenital abnormalities in the fetus. Prophylactic administration in the last trimester of pregnancy in asymptomatic VVC cases provides good pregnancy and neonatal outcomes but is still being debated. In severe, prolonged or recurrent cases of VVC, other co-infections may be sought which may also need to be managed. Administration of probiotics for VVC therapy still requires further research.","PeriodicalId":13477,"journal":{"name":"Indonesian Journal of Obstetrics and Gynecology","volume":"23 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141119430","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected using a semi-structured questionnaire through face-to-face interviews with antenatal mothers regarding their demographic profile, obstetric history, nutrition, and lifestyle. The level of stress was assessed using the Perceived Stress Scale. Oral glucose tolerance tests (OGTT) were performed after an overnight fast of at least 12 hours, with a 75 g glucose load administered, and venous samples were drawn after 2 hours.

GDM mothers with a family history of chronic diseases like diabetes, hypertension, and heart disease (p=0.009), as well as those with an increased number of pregnancies, had a higher risk of gestational diabetes (47.6%), which was statistically significant (p=0.001).

The study examined various adverse pregnancy outcomes in relation to antiretroviral treatment. Statistical analysis employed chi-square and Fisher’s exact tests to determine differences in distribution proportions of patients on ART versus those not on ART across various antenatal and neonatal complications, with significance attributed to p-values <0.05. \u0000Results: A total of 155 patients were found to be HIV positive.
