Abstract
Background
Isocitrate dehydrogenase 1/2 (IDH1/2), BAP1, ARID1A and PBRM1 have been reported as the most frequent mutant genes in intrahepatic cholangiocarcinoma (ICC), and their relationships with clinicopathological features and prognosis were researched in this study.

Methods
We collected clinical data of 130 ICC patients from January 2012 to December 2017. The IDH1/2 mutation and loss of BAP1, ARID1A and PBRM1 expressions were detected by DNA sequencing or immunohistochemical methods, and histological subtype of ICCs was determined by hematoxylin-eosin, Alcian blue and S100P staining.

Results
IDH1/2 mutation was related to decreased preoperative serum total bilirubin (P = 0.039), ferritin (P = 0.000) and higher histological differentiation (P = 0.024), and was associated with prolonged disease-free survival (P = 0.009) and a trend toward increased overall survival (P = 0.126) in small duct type of ICCs. Immunohistochemical staining results of MsMab-1 were generally consistent with DNA sequencing for IDH1/2 mutant in ICCs (κ = 0.691). Only BAP1 expression loss was correlated to prolonged disease-free survival (P = 0.031) and overall survival (P = 0.041) in large duct type of ICCs.

Conclusions
IDH1/2 mutation is a favorable predictor and may be related to iron metabolism in small duct type of ICCs. Furthermore, we suggest that the detection of IDH1/2 mutation is indispensable to determine targeted therapy in small duct type ICCs, while it is not necessary in large duct of ICCs. MsMab-1 is a relatively effective multi-specific antibody against IDH1/2 mutant in ICCs. BAP1 expression loss was correlated with improved prognosis only in large duct type ICCs.
Fertility sparing surgery vs radical surgery for epithelial ovarian cancer: a meta-analysis of overall survival and disease-free survival
Authors: Liu Denghua , Cai Jing , Gao Aiwei , Wang Zehua , Cai Liqiong 
Published: April 2020

Abstract
Background
The aim of this systematic review and meta-analysis was to compare overall survival and disease-free survival after fertility sparing surgery (FSS) vs radical surgery in stage 1 epithelial ovarian cancer (EOC).

Methods
A systematic literature search of PubMed, BioMed Central, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials) and Google scholar was carried out. Databases were searched for English language studies from inception to 1st November 2019. Adjusted hazard ratios (HR) were extracted and pooled for a meta-analysis. Meta-regression was performed for baseline patient characteristics.

Results
Eight observational studies compared 2223 patients undergoing FSS with 5809 patients undergoing radical surgery. Overall survival was reported from all eight studies. The pooled HR was non-significant (HR, 1.03; 95%CI, 0.80–1.31; p = 0.84) denoting no difference in overall survival between FSS and radical surgery. Data on disease-free survival was available from five studies. Our analysis indicated no difference in disease-free survival between EOC patients undergoing FSS or radical surgery (HR, 1.07; 95%CI, 0.73–1.58; p = 0.72). On meta-regression, there was no a statistically significant effect of cancer stage, grade and histology on the pooled HR.

Conclusion
On the basis of currently available observational studies there seems to be no difference in overall survival and disease-free survival with either surgical techniques for stage 1 EOC patients. Disease stage, tumor grade and histology does not appear to influence outcomes. Further homogenous studies shall improve the quality of evidence on this debatable subject.

Published: April 2020

AbstractBackgroundCancer development is mediated by oxidative stress and inflammation, which may correlate with metabolic disorders. The aim of this study was to evaluate antioxidant vitamins status and metabolic parameters in patients with oral cancer according to tumor-node-metastasis (TNM) stages.MethodsA total of 194 patients with oral cancer were enrolled in this study. The patients were stratified for four groups according to cancer stages and that the statistics are comparisons across these groups. The levels of antioxidant vitamins (ubiquinone, β-carotene, vitamin A and E), metabolic parameters, oxidative stress, antioxidant enzymes activity, and inflammatory markers were measured.ResultsMore than half of the subjects had high blood pressure, central obesity, hyperglycemia, and hyperlipidemia regardless of TNM stage. With regard to antioxidant vitamins status, 46 and 94% of patients had β-carotene and ubiquinone deficiency, respectively. Patients in T3 and T4 stages had significantly lower antioxidant enzyme (catalase,p = 0.03) activity and higher inflammatory markers levels (high sensitivity C-reactive protein and interleukin-6,p < 0.01) than patients in the other stages. In addition, the level of β-carotene was negatively associated with waist circumference, and ubiquinone was positively associated with the level of high-density lipoprotein cholesterol (p < 0.05). Higher β-carotene and ubiquinone levels were negatively associated with hypertriglyceridemia and the risk of metabolic syndrome (p < 0.05).ConclusionsA high proportion of patients with oral cancer had ubiquinone or β-carotene deficiency and metabolic disorders. The level of ubiquinone or β-carotene was negatively associated with the risk of central obesity, hypertriglyceridemia, and metabolic syndrome. Since patients with oral cancer suffer from high oxidative stress and inflammation (particularly in the T3 and T4 stages), supplementation with antioxidant vitamins such as ubiquinone or β-carotene could be preferentially applied.
Prevalence and associated factors of active trachoma among 1–9 years old children in Deguatemben, Tigray, Ethiopia, 2018: community cross-sectional study

Published: April 2020

Abstract
Background
Trachoma is a contagious infection of the eye. World Health Organization recommended three rounds of mass drug administration in districts where the prevalence of trachomatous follicular (TF) is ≥10% in children aged 1–9 years. Mass drug distribution was given to residents for three consecutive years with more than 90% coverage. However, the prevalence and associated factors of active trachoma in the study community after the intervention was not yet determined. Thus, this deals with the prevalence and associated factors of active trachoma among children aged 1–9 years.

Methods
We conducted a Community based cross-sectional study among 502 children aged 1–9 in March 2018 in Deguatemben. A multi-stage sampling technique was applied. Selected children were examined for trachoma using 2.5x binocular loupe and graded based on the WHO simplified grading system. Mothers were interviewed for factors associated with trachoma using a structured questionnaire. Data was entered on Epi-Info and exported to SPSS for analysis. Both descriptive and inferential analyses were done with 95% confidence intervals (CIs) at a p-value < 0.05 for the final model.

Results
The prevalence of active trachoma was found 21.5% (95% CI: 17.8–25.1%). Being 1 to 4 years old [AOR (95% CI) = 6.81(2.00–23.11)], not washing face [AOR (95% CI) =9.31(1.13–77.66)], not using soap [AOR (95% CI) =5.84(1.87–18.21)], unclean face [AOR(95% CI) = 18.22(4.93–69.32)] and mother’s knowledge [AOR (95% CI) =0.06(0.02–0.19)] were found as independent predictors.

Conclusion
The prevalence declined from the baseline, but it is still a public health problem in the district. Personal-related factors were found to be associated with the disease. Health education of “Facial cleanness” and related factors is recommended to increase knowledge of the mothers on their children’s care in addition to the provision of antibiotics.

Authors: Chen Ting , Zheng Hongmei , Wang Yunyun , Hu Junyi , Chen Changzheng 
Published: April 2020

Abstract
Background
Bilateral and multiple Valsalva-related sub-internal limiting membrane (ILM) hemorrhages in a familial retinal arteriolar tortuosity (FRAT) patient is rare, and we treated this patient by both observation and Neodymium yttrium aluminum garnet (Nd: YAG) laser membranotomy methods.

Case presentation
A 13-year-old female student presented with sudden visual loss and central scotoma in both eyes after running 800 m at the school gym. The examination revealed six sub-ILM hemorrhages with the biggest hemorrhage measuring approximately 1.5-disc diameters (DD) in the right eye and two sub-ILM hemorrhages with the biggest one measuring 5.5 DD in the left eye. The patient was diagnosed as having Valsalva retinopathy associated with FRAT. Nd: YAG laser membranotomy was performed at the biggest hemorrhages and the rest hemorrhages were treated with observation in both eyes. The visual acuity recovered to 20/16 in the right eye and 20/20 in the left eye. Epiretinal membrane (ERM) formation was observed in the left eye.

Conclusions
Nd: YAG laser could be considered for treating premacular hemorrhage in FRAT patient especially when a quick vision recovery was needed. This is the first reported case of a FRAT patient suffering from bilateral and multiple Valsalva-related sub-ILM hemorrhages which were treated by both observation and Nd: YAG laser treatment.
Ghost cell glaucoma after intravitreous injection of ranibizumab in proliferative diabetic retinopathy

Published: April 2020

Abstract
Background
The development of ghost cell glaucoma in patients with proliferative diabetic retinopathy (PDR) after intravitreous injection (IV) was rare. Here we reported a series of patients with PDR who received Intravitreous Ranibizumab (IVR) and developed ghost cell glaucoma and analyzed the potential factors that might be related to the development of ghost cell glaucoma.

Methods
Retrospective case series study. The medical records of 71 consecutive eyes of 68 PDR patients who received vitrectomy after IVR from January 2015 to January 2017 were reviewed. The development of ghost cell glaucoma after IVR was recorded. Characteristics of enrolled patients were retrieved from their medical charts. Factors associated with ghost cell glaucoma were compared between eyes with the development of ghost cell glaucoma and eyes without the development of ghost cell glaucoma. Variables were further enrolled in a binary backward stepwise logistic regression model, and the model that had the lowest AIC was chosen.

Results
There were 8 out of 71 eyes of the PDR patients developed ghost cell glaucoma after they received IVR. The interval between detection of elevation of intraocular pressure (IOP) and IV ranged from 0 to 2 days. Among them, after IVR, there were two eyes had IOP greater than 30 mmHg within 30 min, four eyes showed normal IOP at 30 min, and then developed ghost cell glaucoma within 1 day, two eyes developed ghost cell glaucoma between 24 and 48 h. The mean IOP was 46.5 ± 8.0 mmHg. All patients gained normal IOP after vitrectomy without medicine for lowering IOP. The presence of ghost cell glaucoma was associated with tractional retinal detachment (RR = 4.60 [2.02 ~ 8.48], p = 0.004) and fibrovascular membrane involving disk (RR = -3.57 [− 7.59 ~ − 0.92], p = 0.03) (AIC = 39.23, AUC = 0.88) in a logistic regression model.

Conclusion
Attention to postoperative IOP should be paid to patients with PDR undergoing vitrectomy who receive a preoperative IV of anti-VEGF agents. PDR patients with tractional retinal detachment or fibrovasucular membrane involving optic disc are more likely to develop ghost cell glaucoma after IV.

Abstract
Background
Available evidence suggests that adjunctive treatment with immunomodulatory medications may be effective in the treatment of major depressive disorder (MDD). A pilot trial of the tetracycline minocycline as adjunctive treatment in treatment-resistant depression (TRD), produced promising results, however, a larger scale trial is needed to confirm the antidepressant actions of this drug.

Methods
This is a 12-week double blind, placebo-controlled, randomized trial of minocycline as an add-on to standard antidepressants for adults (age > 18) with DSM-5 major depressive episode, who have failed to respond to at least two adequate trials of antidepressant treatment. It is a parallel-arm study with 50 participants in each group. The primary outcome measure is change in 17-item Hamilton Depression Rating Scale (HRSD-17) total scores from baseline to week 12. Secondary measures include the Clinical Global Impression (CGI) scale, World Health Organization Quality of Life Short Version (WHOQOL-BREF) and the Generalized Anxiety Disorder scale (GAD-7). Peripheral inflammatory biomarkers will be collected at baseline, week 6 and 12.

Discussion
If minocycline is well tolerated and effective in reducing depressive symptoms in patients with TRD, it would warrant genuine consideration as a treatment option for TRD. Additionally, if results demonstrate that minocycline has antidepressant properties, and that changes in inflammatory status are associated with its antidepressant action, it will inform the development of individualized treatment for a subset of patients with MDD.

AbstractBackgroundMajor depressive disorder is among the most burdening and costly chronic health hazards. Since its prognosis is poor and treatment effectiveness is moderate at best, prevention would be the strategy of first choice. Insomnia may be the best modifiable risk factor. Insomnia is highly prevalent (4–10%) and meta-analysis estimates ±13% of people with insomnia to develop depression within a year. Among people with insomnia, recent work identified three subtypes with a particularly high lifetime risk of depression. The current randomized controlled trial (RCT) evaluates the effects of internet-guided Cognitive Behavioral Therapy for Insomnia (CBT-I), Chronobiological Therapy (CT), and their combination on insomnia and the development of depressive symptoms.MethodsWe aim to include 120 participants with Insomnia Disorder (ID) of one of the three subtypes that are more prone to develop depression. In a two by two factorial repeated measures design, participants will be randomized to CBT-I, CT, CBT-I + CT or treatment as usual, and followed up for one year. The primary outcome is the change, relative to baseline, of the severity of depressive symptoms integrated over four follow-ups spanning one year. Secondary outcome measures include a diagnosis of major depressive disorder, insomnia severity, sleep diaries, actigraphy, cost-effectiveness, and brain structure and function.DiscussionPre-selection of three high-risk insomnia subtypes allows for a sensitive assessment of the possibility to prevent the development and worsening of depressive symptoms through interventions targeting insomnia.Trial registrationNetherlands Trial Register (NL7359).

Social judgments on abortion and contraceptive use: a mixed methods study among secondary school teachers and student peer-counsellors in western Kenya
Authors: Håkansson Miranda , Super Stephanie , Oguttu Monica , Makenzius Marlene 
Published: April 2020

Abstract
Background
In Kenya, unsafe abortion is the leading cause of maternal deaths in adolescent girls aged 15–19 years, and a majority did not use a modern contraceptive before becoming pregnant. The aim of this study was to explore attitudes related to abortion and contraceptive use among secondary school teachers and student peer-counsellors in a low-resource setting in western Kenya.

Methods
A mixed methods design, combining a questionnaire-survey and focus group discussions (FGDs), was utilised to explore attitudes to abortion and contraceptive use among teachers (n = 15) and student peer-counsellors (n = 21) at a secondary school in Kisumu, Kenya. First, two Likert scale questionnaires were used: a modified version of the Stigmatising Attitudes, Beliefs and Actions (SABA) scale and the Contraceptive Use Stigma (CUS) scale. Secondly, four FGDs were conducted. Descriptive statistics and Abductive Thematic Network Analysis (ATNA) were used to analyse the data.

Results
Overall, Social judgments on abortion and contraceptive use were found among teachers and student peer-counsellors, with similar patterns between sexes. Christian and cultural values; A majority, 28/36 considered abortion a sin, and chastity and purity before marriage were highly valued feminine ideals. Discrimination and isolation; 18/36 believed that a girl who has had an abortion might be a bad influence on other girls, and 13/35 stated that an adolescent girl cannot decide for herself if to use a contraceptive method. Conflicting views on abortion and contraceptives; A third (11/34) believed that contraceptives may cause infertility, and its use was related to promiscuity. Girls associated with abortion and contraceptive use were considered immoral, lacking parental guidance, and were used to represent bad examples in school. Although conflicting views were present, sexuality was considered a taboo topic, which left adolescents ignorant on contraceptive use.

Conclusions
Adolescent girls associated with abortion and contraceptive use are at risk for social judgements and discrimination, by both peers and teachers. Sexual and reproductive health training needs to be implemented in teacher education to increase knowledge on adolescent sexuality, abortion and contraceptive use to improve adolescents’ sexual health and decrease the stigma.

Published: April 2020

Abstract
Background
HIV testing programs in the United States aim to reach ethnic minority populations who experience high incidence of HIV, yet 40% of African Americans have never been tested for HIV. The objective of this study is to identify community-based strategies to increase testing among African Americans in both urban and rural areas.

Methods
This study conducted focus group discussions (FGDs) informed by community-based participatory research principles to examine African American’s concerns and ideas around HIV testing and HIV self-testing. Participants included highly affected (i.e., PLWH, MSM, PWID, low-income, teens and young adults) populations from African American communities in North Carolina, aged 15 years and older. We digitally transcribed and analyzed qualitative data using MAXQDA and axial coding to identify emergent themes.

Results
Fifty-two men and women between 15 to 60 years old living in urban (n=41) and rural (n=11) areas of North Carolina participated in focus group discussions. HIV testing barriers differed by HIV testing setting: facility-based, community-based, and HIV self-testing. In community-based settings, barriers included confidentiality concerns. In facility-based settings (e.g., clinics), barriers included negative treatment by healthcare workers. With HIV self-testing, barriers included improper use of self-testing kits and lack of post-test support. HIV testing facilitators included partnering with community leaders, decentralizing testing beyond facility-based sites, and protecting confidentiality.

Conclusions
Findings suggest that HIV testing concerns among African Americans vary by HIV testing setting. African Americans may be willing to test for HIV at community events in public locations if client confidentiality is preserved and use HIV self-testing kits in private if post-test social support and services are provided. These community-identified facilitators may improve African American testing rates and uptake of HIV self-testing kits.

Abstract
Background
In Nicaragua, cervical cancer is the leading cause of cancer death among women. Human papillomavirus (HPV) testing, primarily using self-sampling, was introduced between 2014 and 2018 in three provinces. We analyzed data from the HPV screening program with the goal of describing key characteristics including reach, HPV prevalence, triage and treatment, and factors associated with follow-up completion.

Methods
We analyzed individual-level data from routinely collected forms for women attending HPV-based cervical cancer screening. HPV-positive women were triaged with Pap or visual inspection with acetic acid (VIA) prior to treatment. Logistic regression was used to identify factors associated with receiving triage and treatment; analyses were adjusted for province, age, and self- vs. provider-collected sampling.

Results
Forty-four thousand six hundred thirty-five women were screened with HPV testing; 96.6% of women used self-sampling. Six thousand seven hundred seventy-six women were HPV positive (15.2%), 54.0% of screen-positive women received triage, and 53.1% of triage-positive women were treated, primarily with cryotherapy. If women lost at triage are included, the overall treatment percentage was 27.8%. Province and provider sampling were significantly associated with completing triage. Province and triage type were significantly associated with receiving treatment. The odds of receiving treatment after Pap triage as compared to VIA was significantly lower (aOR: 0.05, 95% CI: 0.04–0.08, p < 0.001), and the relative proportion of women receiving treatment after Pap triage versus VIA was 0.29.

Conclusions
Introduction of HPV testing resulted in a substantial number of women screened, and acceptance of self-sampling was high. Management of screen-positive women remained a challenge, particularly with Pap triage. Our results can inform other developing countries as they work to reach World Health Organization (WHO) elimination targets.
