Proportion of abnormal second 50-g glucose challenge test in gestational diabetes mellitus screening using the two-step method in high-risk pregnant women.

AIMS: To determine the merit of repeating 50-g glucose challenge test (50-g GCT) at 24-28 weeks of gestation in high-risk pregnant women and the prevalence of early- and late-onset gestational diabetes mellitus (GDM). METHODS: This study was conducted in 1447 pregnant women, 344 of them were at risks for GDM undergoing screening by two-step method at first visit. Data were not completely collected in 47 women leaving only 297 for analyses. Fifty-six of 297 pregnant women were diagnosed as early-onset GDM (18.8%) and the other 241 pregnant women were consequently screened at 24-28 weeks of gestation to identify late-onset GDM. Screening data were retrieved, including risks, laboratory test results, baseline characteristics and diagnostic outcomes. Proportion of abnormal second 50-g GCT and the prevalence of late-onset GDM were estimated. RESULTS: The prevalence of late-onset GDM was 17.8%. Among groups of normal 50-g GCT, abnormal 50-g GCT and abnormal 1 oral glucose tolerance test (OGTT) value at first test, the proportions of abnormal 50-g GCT at second test were 38.3%, 59.5% and 79.3%, and the prevalence of late-onset GDM among each group were 18.8%, 8.3% and 41.4%, consecutively. This lead to prevalence of GDM in this high-risk group of 33.3% and overall among 1447 women was 7.9%. CONCLUSION: There were high proportions of abnormal 50-g GCT at second test in the groups with abnormal 50-g GCT and abnormal 1 OGTT value at first test (59.5% and 79.3%). Authors suggested doing OGTT without repeating 50-g GCT in these groups coming at 24-28 weeks of gestation.

Prevalence and anatomical sites of human papillomavirus, Epstein-Barr virus and herpes simplex virus infections in men who have sex with men, Khon Kaen, Thailand.

BACKGROUND: Human papillomavirus (HPV), Epstein-Barr virus (EBV) and herpes simplex virus (HSV) cause sexually transmitted diseases (STDs) that are frequently found in men who have sex with men (MSM) with human immunodeficiency viral (HIV) infection. METHODS: This study investigated the prevalence of infection and anatomical site distribution of these viruses in asymptomatic MSM. DNA, extracted from cells collected from the anorectum, oropharynx and urethra of 346 participants, was investigated for the presence of EBV, HPV and HSV using real-time PCR. Demographic data from the participants were analyzed. RESULTS: All three viruses were found in all sampled sites. EBV was the commonest virus, being detected in the anorectum (47.7% of participants), oropharynx (50.6%) and urethra (45.6%). HPV and HSV were found in 43.9% and 2.9% of anorectum samples, 13.8% and 3.8% of oropharynx samples and 25.7% and 2% of urethra samples, respectively. HPV infection of the anorectum was significantly associated with age groups 21-30 (odds = 3.043, 95% CI = 1.643-5.638 and P = 0.001) and 46-60 years (odds = 2.679, 95% CI = 1.406-5.101 and P = 0.03). EBV infection of the urethra was significantly correlated with age group 21-30 years (odds = 1.790, 95% CI = 1.010-3.173 and P = 0.046). EBV/HPV co-infection of the anorectum (odds = 3.211, 95% CI = 1.271-8.110, P = 0.014) and urethra (odds = 2.816, 95% CI = 1.024-7.740, P = 0.045) was also associated with this age group. Among HIV-positive MSM, there was a significant association between age-group (odds = 21.000, 95% CI = 1.777-248.103, P = 0.016) in HPV infection of the anorectum. A failure to use condoms was significantly associated with HPV infection of the anorectum (odds = 4.095, 95% CI = 1.404-11.943, P = 0.010) and urethra (odds = 7.187, 95% CI = 1.385-37.306, P = 0.019). Similarly, lack of condom use was significantly associated with EBV infection of the urethra (odds = 7.368, 95% CI = 1.580-34.371, P = 0.011). CONCLUSION: These results indicate that asymptomatic MSM in Northeast Thailand form a potential reservoir for transmission of STDs, and in particular for these viruses.

Antibiotics for infection prevention after excision of the cervical transformation zone.

BACKGROUND: Excision of the transformation zone of the cervix is the most commonly used approach to treat cervical precancerous lesions (cervical intraepithelial neoplasia (CIN)) to reduce the risk of developing cervical cancer. As the excision of the transformation zone leaves a raw area on the cervix, there is a risk of infection following the procedure. The incidence of infection after cold knife conization (CKC) is 36%, whereas the incidence for large loop excision of the transformation zone (LLETZ, also known as loop electrical excision procedure (LEEP)) is much lower (0.8% to 14.4%). Prophalytic antibiotics may prevent an infection developing and are often prescribed for CKC. However, there are no formal recommendations regarding the use of prophylactic antibiotics for infection prevention in women undergoing surgical excisional treatment for cervical precancerous lesions. OBJECTIVES: To evaluate the effectiveness and safety of antibiotics for infection prevention following excision of the cervical transformation zone. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2016, Issue 4), MEDLINE, Embase, LILACS to May 2016. We also checked registers of clinical trials, citation lists of included studies, key textbooks and previous systematic reviews for potentially relevant studies SELECTION CRITERIA: We included randomised controlled trials (RCTs) evaluating the effectiveness and safety of prophylactic antibiotics versus a placebo or no treatment in women having excision of the cervical transformation zone, regardless of the type of surgical excisional method used. DATA COLLECTION AND ANALYSIS: We used standard methodological procedures expected by Cochrane. Two review authors independently selected potentially relevant trials, extracted data, and assessed risk of bias, compared results and resolved disagreements by discussion. We contacted investigators for additional data, where possible. MAIN RESULTS: Of the 370 records that we identified as a result of the search (excluding duplicates), we regarded six abstracts and titles as potentially relevant studies. Of these six studies, three met the inclusion criteria involving 708 participants; most trials were at moderate or high risk of bias (risk mainly due to lack of blinding and high rate of incomplete data). We did not identify any ongoing trials. Although all included studies had been published in peer-reviewed journals at the time of the search and data extraction, numerical data regarding the outcome measured in one trial involving 77 participants were insufficient for inclusion in a meta-analyses.The difference in the rates of prolonged vaginal discharge or presumed cervicitis (one study; 348 participants; risk ratio (RR), 1.29; 95% confidence interval (CI) 0.72 to 2.31; low-quality evidence) and severe vaginal bleeding (two studies; 638 participants; RR 1.21; 95% CI 0.52 to 2.82; very low-quality evidence) among the two comparison groups did not reach the level for clinically important effect. In addition, there was no difference in adverse events related to antibiotics i.e. nausea/vomiting, diarrhoea, and headache among the two comparison groups (two studies; 638 participants; RR 1.69; 95% CI 0.85 to 3.34; very low-quality evidence). There were no differences in the incidence of fever (RR, 2.23; 95% CI 0.20 to 24.36), lower abdominal pain (RR, 1.03; 95% CI 0.61 to 1.72), unscheduled medical consultation (RR 2.68, 95% CI 0.97 to 7.41), and additional self-medication (RR 1.22; 95% CI 0.56 to 2.67) between the two comparison groups (one study; 290 participants; low to very low-quality evidence). AUTHORS' CONCLUSIONS: As only limited data are available from three trials with overall moderate to high risk of bias, there is insufficient evidence to support use of antibiotics to reduce infectious complications following excision of the cervical transformation zone. In addition, there were minimal data about antibiotic-related adverse events and no information on the risk of developing antibiotic resistance. Antibiotics given for infection prevention after excision of the cervical transformation zone should only be used in the context of clinical research, to avoid unnecessary prescription of antibiotics and to prevent further increases in antibiotic resistance.

FACTORS ASSOCIATED WITH THE DECISION TO HAVE HIV ANTIBODY TESTING AMONG THAI MEN WHO HAVE SEX WITH MEN.

The aim of this study was to assess the factors associated with the deci- sion to have HIV antibody testing among Thai men who have sex with men (MSM) during the previous 12 months. MSM were recruited by systematic sampling from the M-REACH membership registry. Variables collected were demographics, sexual behavior, health behavior, knowledge about HIV/AIDS prevention and attitudes about HIV antibody testing. Data were collected via a self-administered questionnaire and in-depth interviews. About one third of participants reported having HIV antibody testing during the previous 12 months. Of those, 65% were aged > 24 years. Participants aged > 24 years were significantly more likely to have HIV testing than those aged < 24 years (AOR = 3.04, 95% CI: 1.12-8.28; p < 0.005). Most participants exhibited a good knowledge and attitude (levels regarding HIV antibody testing and AIDS). Those with a good attitude level about HIV were more likely to have been tested than those with a poor attitude level (AOR = 3.19; 95% CI: 1.24-8.22; p < 0.005). A programs that improves attitude and knowledge levels about HIV testing need to be developed for MSM in Thailand to improve HIV antibody testing rates.

Differential methylation of E2 binding sites in episomal and integrated HPV 16 genomes in preinvasive and invasive cervical lesions.

Enhanced expression of the HPV 16 E6-E7 oncogenes may trigger neoplastic transformation of the squamous epithelial cells at the uterine cervix. The HPV E2 protein is a key transcriptional regulator of the E6-E7 genes. It binds to four E2 binding sites (E2BSs 1-4) in the viral upstream regulatory region (URR). Modification of E2 functions, for example, by methylation of E2BSs is hypothesized to trigger enhanced expression of the viral E6-E7 oncogenes. In the majority of HPV-transformed premalignant lesions and about half of cervical carcinomas HPV genomes persist in an extra-chromosomal, episomal state, whereas they are integrated into host cells chromosomes in the remaining lesions. Here we compared the methylation profile of E2BSs 1-4 of the HPV 16 URR in a series of 18 HPV16-positive premalignant lesions and 33 invasive cervical cancers. CpGs within the E2BSs 1, 3, and 4 were higher methylated in all lesions with only episomal HPV16 genomes compared with lesions displaying single integrated copies. Samples with multiple HPV16 integrated copies displayed high methylation levels for all CpGs suggesting that the majority of multiple copies were silenced by extensive methylation. These data support the hypothesis that differential methylation of the E2BSs 1, 3 and 4 is related to the activation of viral oncogene expression in cervical lesions as long as the viral genome remains in the episomal state. Once the virus becomes integrated into host cell chromosomes these methylation patterns may be substantially altered due to complex epigenetic changes of integrated HPV genomes.

Feasibility of community-based careHPV for cervical cancer prevention in rural Thailand.

OBJECTIVE: This study aimed to assess the safety, acceptability and feasibility of primary human papillomavirus (HPV) testing for cervical cancer prevention at the community level in a low-resource setting. MATERIALS AND METHODS: After training a technician to run specimens on the careHPV unit, the study team traveled to a different village each day in rural Roi-et Province, Thailand. Women were tested for HPV using self-swab, followed by careHPV testing. Those with positive result were assessed immediately by visual inspection with acetic acid. Women positive for HPV and visual inspection with acetic acid were offered cryotherapy. Safety was determined by monitoring adverse events. Exit surveys assessed acceptability and feasibility. Feasibility was also assessed by measuring testing and triage throughputs. RESULTS: Technician training required 2.5 days to achieve competency. A total of 431 women were screened in 14 days, with an average of 31 women screened daily. No adverse events were reported. Women deemed the program overwhelmingly acceptable: 90.5% reported that they would take the self-swab again, 71.3% preferred the self-swab to a clinician swab. The program was also feasible: 99.8% of eligible women agreed to testing, 94.8% returned for same-day follow-up, and women only spent 30 to 50 minutes of their total time with the program from screening to results. CONCLUSIONS: Cervical cancer prevention programs based on self-swab HPV testing could be safe, acceptable, feasible, and effective at the community level in low-resource settings.

Efficacy and Safety of Vernonia cinerea for Smoking Cessation: An Open-Label Randomized Controlled Trial.

This study aimed to compare the efficacy and safety of Vernonia cinerea (VC) and nortriptyline for smoking cessation. A randomized, active-comparator, open-label trial was conducted in 2019. A total of 84 patients participated in the study, and equally randomized with 42 participants in each group. Overall, there was no statistically significant difference of continuous abstinence rate (CAR) between VC and nortriptyline group (Odd ratio 0.68, 95%CI 0.25-1.85, P=0.451). After week 12, the end of treatment, CAR between both groups was not different (44.44% vs 45.95%, Odd ratio 0.77, 95%CI 0.23-2.54, P>0.999). After follow up by the end of research at week 24, the CAR in both groups was not different (41.67% vs 43.24%, Odd ratio 0.76, 95%CI 0.23-2.55, P>0.999). After week 24, relapse rate between VC and nortriptyline group was not different (13.89% vs 10.81%, P=0.923). In addition, both groups were effective in reducing the number of cigarettes per day compared to baseline. However, there was no difference between the groups. Overall, the VC group had an 8% smoking rate less than nortriptyline group, but not statistically significant (IRR 0.92, 95%CI 0.59-1.43, P=0.702). They also resulted in reducing the exhaled CO level at treatment period and wash out period (at week 12; 7(-17-20) vs 7(-12-16), mean difference 0.78, 95%CI -3.07-4.63, P>0.999, at week 24; 8(-5-22) vs 8.5(-5-17), mean difference 0.39, 95%CI -3.46-4.24, P>0.999). Overall, there was no difference between either group (mean difference -0.31, 95%CI -3.10-2.47). For safety data, adverse events including tongue bitter taste or numbness were found in VC group to be greater than in nortriptyline group (61.9% vs 30.95%, P=0.004), whereas dry mouth and drowsiness were greater found in nortriptyline group (35.71% vs 90.48%, P<0.001 and 16.67% vs 90.48%, P<0.001, respectively). Serious adverse events were not found. In smoking cessation, efficacy and safety of either VC or nortriptyline showed no difference.

Effect of topical Zingiber cassumunar on painful diabetic neuropathy: a double-blind randomized-controlled trial.

Background: Plai or Zingiber cassumunar Roxb. was registered into the Thai Traditional Medicine list since 2011. However, there is limited evidence regarding Plai as a treatment in painful diabetic neuropathy (PDN). Therefore, this study aimed to evaluate the efficacy of topical Zingiber cassumunar. Methods: A RCT was conducted in patients with PDN during February to March 2019. All participants received oral gabapentin 300 mg before bed as a standard regimen. The intervention group (n=16) received Plai balm 15%w/w 0.5 gram to apply on their feet three times a day and the control group (n=15) received placebo balm to similarly apply. Pain score at baseline, 2 nd and 4 th weeks were assessed and compared. Patients' quality of life, and adverse events, were collected. Mean pain scores before and after treatment in each group and between groups were also analyzed. Results: At the end of week two and week four, the Plai group showed statistically significant lesser mean pain scores than the placebo group by -1.47 (95%CI: -1.96 to -1.30, p-value < 0.001), and by -1.51 (95%CI: -1.92 to -0.13, p-value = 0.027), respectively. Moreover, the Plai group had more cases number/ percentages with at least 50% pain score reduction than the placebo group [12/16 (75%) vs 3/15 (20%), p-value = 0.004]. However, there was no statistically significant difference in quality of life between the two groups (overall p-value = 0.366). Adverse event was not found in any groups. Conclusions: Zingiber cassumunar balm (Plai) was efficacious for pain reduction in painful diabetic neuropathy. Registration: Registered with the Thai Clinical Trials Registry; TCTR20200221001.

Clinical outcomes of immunohistochemistry of the p53 Staining pattern in high-grade serous ovarian carcinoma.

OBJECTIVE: To investigate the prevalence of p53 mutations and associated factors between immunohistochemistry (IHC) and p53 staining patterns among patients with high-grade serous ovarian carcinoma (HGSOC). METHODS: This study is a retrospective review. A total of 62 patients with HGSOC underwent surgery at Srinagarind Hospital between January 2016 and December 2020. Histological examination was performed based on a combination of morphology and IHC staining with p53. The p53 immunostaining pattern was interpreted as a missense mutation, nonsense mutation, or a wild-type pattern. Missense (p53 overexpression pattern) and nonsense (null expression p53 pattern) mutations were considered p53 mutations. A wild-type pattern was defined as a p53 non-mutation. RESULTS: p53 mutations were identified in 93.6% of the patients. Subgroup analysis of the p53 mutation group between the p53 overexpression pattern and the p53 null expression pattern in terms of clinicopathological characteristics and initial treatment was performed. Patients with the p53 overexpression pattern had significantly more omental metastases than those with the p53 null expression pattern (87.8% vs. 64.7%, P=0.042). There were no statistically significant differences in median progression-free survival (PFS) (9 vs. 10 months, P=0.813) or median overall survival (OS) (12 vs. 17 months, P=0.526) between the two groups. CONCLUSION: The prevalence of p53 mutations in HGSOC patients in this study was 93.6%. Omental metastasis is a significant pathological factor in predicting overexpression p53 pattern in HGSC. However, IHC analysis of the p53 staining pattern did not affect OS or PFS among patients with HGSOC.

Predictive value of 'Smartscopy' for the detection of preinvasive cervical lesions during the COVID-19 pandemic: a diagnostic study.

OBJECTIVE: To evaluate the performance of "Smartscopy" in diagnosing preinvasive cervical lesions among patients with abnormal cervical cancer screening results obtained during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: This diagnostic study enrolled non-pregnant women with abnormal cervical cancer screening results obtained at the colposcopy clinic at Srinagarind Hospital (Khon Kaen, Thailand) between September 2020 and March 2021. Two colposcopists independently evaluated the uterine cervix using a smartphone and colposcopy. Cervical biopsies and endocervical curettage were performed in accordance with standard procedures. The diagnostic performance of a smartphone in detecting low-grade squamous intraepithelial lesions or worse plus (LSIL+) and high-grade squamous intraepithelial lesions plus (HSIL+) was assessed. RESULTS: In total, 247 patients were included. There was high agreement between the two colposcopists (κ=0.88; 95% confidence interval [CI], 0.82-0.93). The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of the smartphone to detect LSIL+ were 96.6% (95% CI, 91.6-99.1), 12.9% (95% CI, 8.06-19.2), 46.2% (95% CI, 39.7-52.4), 83.3% (95% CI, 62.6-95.3), and 0.49% (95% CI, 0.43-0.55), respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of smartscopy in diagnosing HSIL+ were 67.6% (95% CI, 55.2- 78.5), 85.4% (95% CI, 79.9-90.0), 60.5% (95% CI, 48.6-71.6), 88.9% (95% CI, 83.7-92.9), and 81.0% (95% CI, 0.75-0.85), respectively. CONCLUSION: Smartscopy demonstrated a remarkable correlation with colposcopy and a high diagnostic performance value for the detection of preinvasive cervical lesions. Therefore, smartscopy may be an alternative tool for detecting abnormal cervical lesions in low to medium medical resource settings. Smartscopy may be applied in telemedicine during the COVID-19 pandemic.

Effect of single-visit VIA and cryotherapy cervical cancer prevention program in Roi Et, Thailand: a preliminary report.

AIM: To assess the effect of introducing visual inspection with acetic acid and cryotherapy on cervical cancer incidence rates in Roi Et province over time, between 1997 and 2006, and compare this with two nearby provinces. METHODS: Data from two cancer registration units, one in Srinagarind Hospital and another in Ubon Ratchathani Cancer Center (to which all cervical cancer patients were referred from the three study provinces) were registered, extracted, combined and analyzed using a generalized estimation equation. RESULTS: Cervical cancer detection rates improved. These are represented by the apparent increased incidence rates in Roi Et province during the study period compared with two nearby provinces (P = 0.01), equivalent to a doubling of the previously reported age-standardized incidence ratio and three times its baseline in 2006. CONCLUSIONS: A single-visit approach to cervical cancer prevention in Roi Et province using visual inspection with acetic acid and cryotherapy appeared to have an effect in revealing an increased cervical cancer incidence rate by achieving higher coverage, resulting in increased case finding.

Effects of Mefenamic Acid in Pain Control during Loop Electrical Excision Procedure:A Prospective Double-Blind Randomized Control Trial.

OBJECTIVE: To investigate the effectiveness of pre-procedural oral mefenamic acid compared with placebo in women undergoing Loop Electrosurgical Excision Procedure (LEEP) with intracervical lidocaine injection. STUDY DESIGNS: A prospective double-blinded randomized control trial. Materials, Setting, Methods: Women undergoing LEEP for any indications were asked to participate in the study. The participants were randomly allocated into two groups. In group 1 (oral mefenamic acid), the participants were offered oral mefenamic acid (500 mg) for 30 minutes before procedures. In group 2 (placebo), the patients were given oral placebo (identical tablet) for 30 minutes before operation. All participants received immediate 10 mL of 2% lidocaine with 1:100,000 of epinephrine intracervical injection before undergoing the LEEP. All participants were excised in one piece of LEEP. No top-hat excision in this study.  The patients graded their pain on a 10-cm visual analog scale (VAS) at different points during the procedure, including speculum insertion, at starting excision, and 30 minutes post excision. Primary outcomes revealed the difference of VAS during all steps of LEEP by generalized estimating equations procedure. RESULTS: Sixty participants (30 in mefenamic group and 30 in placebo group) participated in this study. The study did not find differences of VAS during all steps of LEEP and analgesic drug requirement at 30 minutes after LEEP procedure. All patients reported no immediate complications and no intervention-related adverse events were observed. CONCLUSION: Using pre-procedural oral mefenamic acid before LEEP procedure was not associated with pain reduction during all steps of excision.

Knowledge and Attitude Toward Human Papillomavirus Infection and Vaccination among Thai Women: A Nationwide Social Media Survey.

OBJECTIVES: This study was performed first to assess Thai women's knowledge and attitude toward Human papillomavirus (HPV) infection and vaccination and second to find out factors associated with knowledge in this regard. METHODS: The survey announcement was advertised via Facebook from 17 May 2019 to 14 June 2019 to recruit women aged 18-26 years living in Thailand. A score below 5 out of total score of 10 on the survey was considered as a poor level of knowledge. Multivariate analysis was applied to identify factors associated with HPV infection and vaccination knowledge. RESULTS: A total of 1,175 participants were recruited. The participants' median age was 22 years. Approximately, 46% of the participants had poor level of knowledge regarding HPV infection and vaccination. Factors associated with poor knowledge included low educational level (adjusted OR, 1.35; 95% CI 1.04-1.77), low family income (adjusted OR, 2.14; 95% CI 1.65-2.78), being Christian (adjusted OR, 4.04; 95% CI 1.22-13.40), being engaged in sexual intercourse (adjusted OR, 0.75; 95%CI 0.58-0.97), and being unvaccinated against HPV infection (adjusted OR, 5.74; 95% CI 3.07-10.74). CONCLUSION: Nearly half of the Thai women who participated in the survey had poor level of knowledge regarding HPV infection and vaccination, indicating a need for more effective health education intervention. Factors associated with knowledge included socioeconomic status and sexual behavior.

Preventing cervical cancer: stakeholder attitudes toward CareHPV-focused screening programs in Roi-et Province, Thailand.

OBJECTIVE: To assess which of the 5 CareHPV-inclusive protocols stakeholders in Roi-et Province, Thailand found (1) most preferable and (2) most beneficial to the overall goal of reducing cervical cancer. DESIGN: Five CareHPV-inclusive cancer prevention approaches were presented to a convenience sample of colposcopists, trainers, health care providers, district medical directors, and district health officers. Participants ranked their preference for each plan (A-E) compared with the current screening protocol and also the perceived comparative benefit of the plans. Plans differed in whether every patient was screened using both the human papillomavirus (HPV) test and visual inspection with acetic acid (VIA) or only HPV-positive women were screened with VIA; in clinician versus self-swab and in hospital/clinic-based or village-based screening. RESULTS: Overall, participants supported an innovative plan in which women would be screened in their homes and villages using the self-swab version of the CareHPV DNA test, and only those who screened positive for HPV are screened with VIA. When results were stratified by provider type (physician vs nonphysician) and/or practice concentration (hospital-oriented vs field-oriented), preference and perceived benefit for the plans differed significantly with physician/hospital-oriented participants and are more likely to be skeptical of the self-swab version of the CareHPV test. CONCLUSIONS: Providers in Thailand recognize the potential value of a rapid HPV test as part of a cervical cancer prevention program and, overall, support a patient-administered self-swab followed by visual confirmation and treatment as the most practical CareHPV-inclusive approach largely because of the likely increase in coverage. Future studies will further define the clinical benefits and limitations of this test.

An evaluation by midwives and gynecologists of treatability of cervical lesions by cryotherapy among human papillomavirus-positive women.

OBJECTIVES: To estimate efficacy of a visual triage of human papillomavirus (HPV)-positive women to either immediate cryotherapy or referral if not treatable (eg, invasive cancer, large precancers). METHODS: We evaluated visual triage in the HPV-positive women aged 25 to 55 years from the 10,000-woman Guanacaste Cohort Study (n = 552). Twelve Peruvian midwives and 5 international gynecologists assessed treatability by cryotherapy using digitized high-resolution cervical images taken at enrollment. The reference standard of treatability was determined by 2 lead gynecologists from the entire 7-year follow-up of the women. Women diagnosed with histologic cervical intraepithelial neoplasia grade 2 or worse or 5-year persistence of carcinogenic HPV infection were defined as needing treatment. RESULTS: Midwives and gynecologists judged 30.8% and 41.2% of women not treatable by cryotherapy, respectively (P < 0.01). Among 149 women needing treatment, midwives and gynecologists correctly identified 57.5% and 63.8% (P = 0.07 for difference) of 71 women judged not treatable by the lead gynecologists and 77.6% and 59.7% (P < 0.01 for difference) of 78 women judged treatable by cryotherapy. The proportion of women judged not treatable by a reviewer varied widely and ranged from 18.6% to 61.1%. Interrater agreement was poor with mean pairwise overall agreement of 71.4% and 66.3% and kappa's of 0.33 and 0.30 for midwives and gynecologists, respectively. CONCLUSIONS: In future "screen-and-treat" cervical cancer prevention programs using HPV testing and cryotherapy, practitioners will visually triage HPV-positive women. The suboptimal performance of visual triage suggests that screen-and-treat programs using cryotherapy might be insufficient for treating precancerous lesions. Improved, low-technology triage methods and/or improved safe and low-technology treatment options are needed.

Efficacy of Curcuma longa in treatment of postprandial distress syndrome: An open-label randomized-controlled trial.

Background: Proton pump inhibitors are effective for functional dyspepsia but ineffective in relieving postprandial distress syndrome. Curcuma longa might be effective for postprandial distress syndrome. The objective of this study was to compare the efficacy of Curcuma longa and simethicone for postprandial distress syndrome in an open-label randomized-controlled trial. Methods: This trial was conducted between July 2018 and February 2019. In total, 78 patients were randomly assigned to receive 4 weeks of treatment with 750 or 1,500 mg oral Curcuma longa per day or 240 mg simethicone per day. The patients assessed their symptoms using the dyspepsia Global Overall Symptom scale at baseline, week 2, and week 4. After stopping medication for 2 weeks, the patients assessed recurrent symptoms and day of recurrence by themselves at the end of week 6. Results: In total, 78 patients underwent randomization (27 in 750 mg Curcuma longa, 26 in 1500 mg Curcuma longa, and 25 in simethicone groups). After 2 weeks, there were no significant differences in all mean changes of symptoms scores (95%CI) of postprandial distress syndrome [-4.1 (-4.5, -2.6) vs -4.3 (-5.2, -3.3) vs -4.2 (-4.8, -3.5), P=0.954]. Over a period of 4 weeks, the reduction in mean scores was greater among participants receiving simethicone (although not statistically significant) compared with two intervention groups [-4.6 (-5.7, -3.6) vs -5.4 (-6.6, -4.1) vs -6.2 (-7.2, -5.2), P=0.122]. The rate of recurrence was significantly lower in simethicone than the two Curcuma longa groups (42.9 vs 45.5 vs 13.6%, P=0.047). There was no serious adverse event reported in all three groups. Conclusions:Curcuma longa had a similar effect on treatment outcomes to simethicone after 2 and 4 weeks, but the recurrence rate of symptoms was significantly higher without serious adverse events.

Prevalence and factors associated with gonorrhea infection with respect to anatomic distributions among men who have sex with men.

INTRODUCTION: Gonorrhea (GC) infection caused by Neisseria gonorrhoeae has been steadily increasing in Thailand over the last decade. Men who have sex with men (MSM) are at high risk for gonorrhea infection. MATERIALS AND METHODS: In this study, we determined the prevalence of and risk factors associated with gonococcal infections by three anatomical sites among MSM. We have conducted a cross-sectional analysis of a sexually transmitted disease (STD), gonorrhea among MSM attending two STD clinics in Khon Kaen, Thailand. We included 358 MSM over 18 years of age. Data were collected using self-administered questionnaire. In each participant, an oropharyngeal, anorectal, and endourethral swab were tested with culture and nucleic acid amplification test (NAAT). However, 267 urine samples were tested by both methods. Factors associated with gonorrhea infections were assessed using univariate and multivariate logistic regression. RESULTS: One hundred and ninety-five out of 358 (54.47%) MSM tested were found to be positive for gonorrhea using a porA gene targeted NAAT by Real-time PCR with TaqMan probes, but there was no positive result by culture. The gonorrheal prevalence for male genital site, anal, and oropharyngeal, were 34.73% (95%CI 33.07, 45.08), 29.01% (95%CI 24.61, 34.33), and 27.93% (95%CI 23.35, 32.89), respectively, while 5.9% (21/355) were positive for gonococcal infection in all anatomic sites (oropharynx + anus + urethra) of one participant. Previous history of diagnosed STDs was a significant factor associated urethral gonorrhea (odds ratio = 3.52, 95%CI 1.87-6.66, P Value< 0.001). In addition, having more than one partner was increased urethral gonorrhea (adjusted odds ratio = 2.26, 95%CI 1.10-4.68, P Value = 0.026). 100% of condom use was found decreasing urethral infection (adjusted odds ratio = 0.39, 95%CI 0.15-0.99, P Value = 0.046). CONCLUSIONS: The most common anatomic site of gonorrhea infection was male genital site, and the independent risk factors were having history of diagnosed STDs and having more than one partner in the past 3 months, but 100% condom use was a protective factor of this infection.

Histopathology of Women with "Atypical Squamous Cells Cannot Exclude High-Grade Squamous Intraepithelial Lesion" (ASC-H) Smears

Objectives: To evaluate prevalence of underlying significant pathologies among women with cervical smears rated as 'atypical squamous cells cannot exclude high grade squamous intraepithelial lesion (ASC-H)', as well as associated risk factors. Methods: Medical records were reviewed of all consecutive women with ASC-H smears who had undergone colposcopy at Srinagarind Hospital from January 2008 to July 2016. Significant pathology results included cervical intraepithelial neoplasia (CIN) 2-3, adenocarcinoma in situ (AIS), endometrial hyperplasia, and cancer of any original site. Result: During the study period, 133 women with ASC-H were reviewed. The mean age was 45.3 years (range 21-72). The histopathologic results for the 133 women were as follows: no lesions (58; 43.6%), CIN 1 (34; 25.6%), CIN 2-3 (33; 24.8%), AIS (2; 1.5%), and cervical cancer (6; 4.5%). The overall rate of significant pathology was 30.8% (95% confidence interval, 22.9%-38.8%). Women younger than 40 years old carried a higher risk of harboring significant lesions when compared to older women (41.7% versus 27.8%, respectively). There was no significant impact of parity and menopausal status on the risk of significant pathology results. Conclusion: The rate of significant histopathologies among women with ASC-H smears in this study was approximately 31% and the associated risk factor was patient age.

Association of Abnormal Pap Smear with Occult Cervical Stromal Invasion in Patients with Endometrial Cancer.

Objective: The purpose of this study was to determine the association between abnormal preoperative Pap smear results and occult cervical stromal invasion in endometrial cancer patients. Methods: Medical records were reviewed of patients with endometrial cancer who had undergone surgical staging at Srinagarind Hospital. Patients with gross cervical involvement, with an unsatisfactory Pap smear, without available Pap smear results, with no cervical intraepithelial lesion/invasive cervical cancer, or who had previously undergone pelvic radiation therapy were excluded. The patients were assigned to one of two groups according their Pap smear results (negative and epithelial cell abnormalities). Logistic regression was used to determine the independent association between an abnormal Pap smear and the risk of cervical stromal invasion. Results: All cervical smears in this study were performed as conventional Pap smears. Smears were abnormal in 50 (21.0%) of the 238 patients enrolled and normal in the remaining 188 (79.0%). The types of Pap smear abnormalities included adenocarcinoma (n=22); atypical endometrial cells (n=2); atypical glandular cells (n=17); high-grade squamous intraepithelial lesions (n=4); atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesions (n=2); and atypical squamous cells of undetermined significance (n=3). After controlling for type of endometrial cancer, abnormal Pap smear results were found to be a significant independent factor that indicated cervical stromal invasion (adjusted OR 2.65; 95% CI 1.35 to 5.21). Conclusion: Endometrial cancer patients with abnormal Pap smears were strongly and independently associated with histopathologically diagnosed cervical stromal invasion.

Impact of Coexisting Uterine Adenomyosis on the Survival Outcome of Patients with Endometrial Cancer: A Retrospective Cohort Study

Objective: To determine the effects of uterine adenomyosis on endometrial cancerrecurrence rates. Methods: This retrospective cohort study reviewed all consecutive patients diagnosed with endometrial cancerwho underwent total hysterectomy-based surgical staging at Srinagarind Hospital between January, 2010 and January, 2016. The patientswere divided into two groups:a uterine adenomyosisgroup and a non-adenomyosis group. Patient demographics, type of surgery, histopathology, stage of endometrial cancer, adjuvant treatment, and survival outcomes were compared. Results: A total 350 patients were enrolled, with 132 (37.71%) in the adenomyosis group and 218 (62.29%) in the nonadenomyosis group. Deep myometrial invasion and lymphovascular space invasion (LVSI) were more commonly found among patients who had no adenomyosis compared to those with adenomyosis(52.8% vs 39.4%, P=0.02 and 53.2% vs. 38.6%, P=0.01). There were no significant differences in terms of five-year recurrence-free survival (HR=1.47; 95%CI 0.88-2.44) and five-year overall survival (HR=0.81; 95%CI 0.43-1.53) between the two comparison groups. Conclusion: Coexisting uterine adenomyosis in endometrial cancer wasassociated withdeep myometrial invasion and LVSI but did not have significant impact on survival.
