AbstractBackgroundNearly all uterine cervical cancer (UCC) cases result from human papillomavirus (HPV) infection. After high-risk HPV infection, most HPV infections are naturally cleared by humoral and cell-mediated immune responses. Thus, cervical lesions of only few patients progress into cervical cancer via cervical intraepithelial neoplasia (CIN) and lead to persistent oncogenic HPV infection. This suggests that immunoregulation plays an instrumental role in the carcinogenesis. However, there was a few studies on the relation between the immunologic dissonance and clinical characteristics of UCC patients.MethodWe examined the related immune cells (Th1, Th2, Th17, and Treg cells) by flow cytometric analysis and analyzed their relations with UCC stages, tumor size, differentiation, histology type, lymph node metastases, and vasoinvasion. Next, we quantified the Th1, Th2, Th17, and Treg cells before and after the operation both in UCC and CIN patients.ResultsWhen compared with stage I patients, decreased levels of circulating Th1 cells and elevated levels of Th2, Th17, and Treg cells were detected in stage II patients. In addition, the imbalance of Th1/Th2 and Th17/Treg cells was related to the tumor size, lymph node metastases, and vasoinvasion. We found that immunological cell levels normalized after the operations. In general, immunological cell levels in CIN patients normalized sooner than in UCC patients.ConclusionsOur findings suggested that peripheral immunological cell levels reflect the patient’s condition.
Intimate partner violence as a factor in contraceptive discontinuation among sexually active married women in Nigeria
Authors: KUPOLUYI Joseph Ayodeji 
Published: June 2020

Abstract
Background
In spite of the well-established associations between socioeconomic and demographic factors and the high rate of contraceptive discontinuation among sexually active married contraceptive users, little is known in Nigeria about the relationship between contraceptive discontinuation and sexually active married women who have experienced Intimate Partner Violence (IPV).

Methods
The 2013 Nigeria Demographic and Health Survey data on women’s reproductive calendars and domestic violence were used to investigate the relationship between IPV and contraceptive discontinuation in a year period. A weighted sample size of 1341 women in a union in the domestic violence module, who have experienced IPV, and are using any contraceptive and are not sterilized in the 12 months periods was analyzed using frequency tables and chart, Pearson’s chi-square test, and binary logistic regression model.

Results
The results showed that women who have experienced any type of IPV are 1.28 times more likely to have discontinued contraceptive use although they are still at risk of becoming pregnant (aOR = 1.28, CI: 1.15–1.91; p < 0.05) than those who have not experienced IPV. The tertiary level of education (aOR = 3.94, CI = 1.67–9.29; p < 0.05), unemployed status (aOR = 1.97, CI = 1.07–3.62; p < 0.05), and higher marital duration of 20 years and above (aOR = 4.89, CI = 2.26–10.57; p < 0.05) significantly influenced women who have experienced any types of IPV to discontinue contraceptives even though they are still at risk of becoming pregnant than those who have not experienced IPV.

Conclusion
The study revealed that women who have experienced any form of IPV were significantly influenced by their education, occupation, the number of living children, and marital duration to discontinue contraception while still at risk of becoming pregnant. Thus, the study concludes that intervention programmes aimed at increasing contraceptive prevalence rate should be mindful of IPV which may affect women’s use of contraceptives.
Intimate partner violence and nutritional status among nepalese women: an investigation of associations
Authors: Adhikari Ramesh P. , Yogi Subash , Acharya Ajay , Cunningham Kenda 
Published: June 2020

Abstract
Background
Malnutrition among women in Nepal persists as a major public health burden. Global literature suggests that domestic violence may have a negative impact on women’s nutritional status. The contribution of intimate partner violence (IPV) to increased stress levels, poor self-care including the consumption of less food and, in turn, malnutrition has been documented. However, there is little empirical evidence on IPV and its relationship with women’s nutritional status in Nepal and thus, this paper assesses these associations.

Methods
We used data on non-pregnant married women (n = 3293) from the 2016 Nepal Demographic and Health Survey (NDHS). The primary exposure variable was whether the women had ever experienced physical, sexual, or emotional violence or controlling behaviours by a current or former partner, based on her responses to the NDHS domestic violence questions. The primary outcome variables were three indicators of malnutrition: under-weight (BMI < 18.5), over-weight (BMI > 25), and anemia (Hb < 11.0 g dL). We used logistic and multinomial regression models, adjusted for potential socio-demographic and economic confounders, as well as clustering, to examine associations between IPV exposure and malnutrition.

Results
Approximately 44% of women had experienced at least one of the four types of IPV. Among them, around 16, 25%. and 44% were underweight, overweight, or anemic, respectively, compared to 13, 29, and 35% of women never exposed to IPV. We did not find any associations between underweight and any of the four types of IPV. Overweight was associated with physical violence (adjusted RRR = 0.67, P < 0.01, CI = 0.50–0.88) and severe physical violence (adjusted RRR = 0.53, P < 0.05, CI = 0.32–0.88) Controlling behaviors were associated with anemia (adjusted RRR = 1.31, P < 0.01, CI = 1.11–1.54).

Conclusions
Among married Nepalese women, physical violence appears to be a risk factor for one’s weight and controlling behaviors for one’s anemia status. Additional, rigorous, mixed-methods research is needed to understand the reporting of IPV and what relationships do or do not exist between IPV experience and nutrition both in Nepal and in other settings.
Identifying essential proteins in dynamic protein networks based on an improved h-index algorithm
Authors: Dai Caiyan , He Ju , Hu Kongfa , Ding Youwei 
Published: June 2020

Abstract
Background
The essential proteins in protein networks play an important role in complex cellular functions and in protein evolution. Therefore, the identification of essential proteins in a network can help to explain the structure, function, and dynamics of basic cellular networks. The existing dynamic protein networks regard the protein components as the same at all time points; however, the role of proteins can vary over time.

Methods
To improve the accuracy of identifying essential proteins, an improved h-index algorithm based on the attenuation coefficient method is proposed in this paper. This method incorporates previously neglected node information to improve the accuracy of the essential protein search. Based on choosing the appropriate attenuation coefficient, the values, such as monotonicity, SN, SP, PPV and NPV of different essential protein search algorithms are tested.

Results
The experimental results show that, the algorithm proposed in this paper can ensure the accuracy of the found proteins while identifying more essential proteins.

Conclusions
The described experiments show that this method is more effective than other similar methods in identifying essential proteins in dynamic protein networks. This study can better explain the mechanism of life activities and provide theoretical basis for the research and development of targeted drugs.

Abstract
Background
Colorectal cancer (CRC) is one of the leading causes of tumor-related death worldwide, and its main cause of death is distant metastasis. Methyltransferase-like 14(METTL14), a major RNA N6-adenosine methyltransferase, is involved in tumor progression via regulating RNA function. The goal of the study is to uncover the biological function and molecular mechanism of METTL14 in CRC.

Methods
Quantitative real-time PCR (qRT-PCR), western blot and immunohistochemical (IHC) assays were employed to detect METTL14 and SOX4 in CRC cell lines and tissues. The biological functions of METTL14 were demonstrated using in vitro and in vivo experiments. Chromatin immunoprecipitation (ChIP), Transcrptomic RNA sequencing (RNA-Seq), m6A-RNA immunoprecipitation sequencing (MeRIP-Seq), RNA immunoprecipitation and luciferase reporter assays were used to explore the mechanism of METTL14 action.

Results
METTL14 expression was significantly downregulated in CRC and decreased METTL14 was associated with poor overall survival (OS). Both the univariate and multivariate Cox regression analysis indicated that METTL14 was an independent prognostic factor in CRC. Moreover, lysine-specific histone demethylase 5C(KDM5C)-mediated demethylation of histone H3 lysine 4 tri-methylation(H3K4me3) in the promoter of METTL14 inhibited METTL14 transcription. Functionally, we verified that METTL14 inhibited CRC cells migration, invasion and metastasis through in vitro and in vivo assays, respectively. Furthermore, we identified SRY-related high-mobility-group box 4(SOX4) as a target of METTL14-mediated m6A modification. Knockdown of METTL14 markedly abolished SOX4 mRNA m6A modification and elevated SOX4 mRNA expression. We also revealed that METTL14-mediated SOX4 mRNA degradation relied on the YTHDF2-dependent pathway. Lastly, we demonstrated that METTL14 might inhibit CRC malignant process partly through SOX4-mediated EMT process and PI3K/Akt signals.

Conclusions
Decreased METTL14 facilitates tumor metastasis in CRC, suggesting that METTL14 might be a potential prognostic biomarker and effective therapeutic target for CRC.

Quality of life among patients with cardiac disease: the impact of comorbid depression
Authors: Bahall Mandreker , Legall George , Khan Katija 
Published: June 2020

Abstract
Background
Patients with cardiac disease with or without depression may also have major physical and mental problems. This study assesses and compares the quality of life (QOL) of patients with cardiac disease with and without depression and accompanying comorbidities.

Methods
A cross-sectional study was conducted with a convenience sample of 388 patients with cardiac disease. The 12-item Short-Form (SF-12)-patient was used to measure physical component scale (PCS) and mental component scale (MCS) QOL, and the Patient Health Questionnaire (PHQ-9) was used to measure depression. The Charlson Comorbidity Index was used to estimate 10-year survival probability. Descriptive statistics, analysis of covariance (ANCOVA), chi-square tests, and binary logistic regression were used for analysis.

Results
The prevalence of minimal to mild depression was 65.7% [(95% CI (60.8, 70.4)] and that of moderate to severe depression was 34.3% [95% CI (29.6, 39.2)]. There was no significant association between the level of PHQ-categorised depression and age (p = 0.171), sex (p = 0.079), or ethnicity (p = 0.407). The overall mean PCS and MCS QOL was 32.5 [95% CI (24.4, 40.64)] and 45.4 [95% CI (44.4, 46.4)], respectively, with no significant correlation between PCS and MCS [r (Pearson’s) = 0.011; p = 0.830)]. There were QOL differences among the five PHQ categories (PCS: p = 0.028; MCS: p ≤ 0.001) with both MCS and PCS decreasing with increasing depression. ANCOVA (with number of comorbidities as the covariate) showed a significant age × ethnicity interaction for PCS (p = 0.044) and MCS (p = 0.039), respectively. Young Indo-Trinidadians had significantly lower PCS than did Afro-Trinidadians, while the converse was true for MCS. Depression, age, and number of comorbidities were predictors of PCS, while depression, age, and sex were predictors of MCS.

Conclusions
Increasing severity of depression worsened both PCS and MCS QOL. Age and level of clinical depression predicted QOL, with number of comorbidities predicting only PCS and sex predicting only MCS. Efforts must be made to treat depression in all age groups of patients with cardiac disease.

Published: June 2020

Abstract
Background
Acupuncture is well recognized for its unique therapeutic effect for many diseases as a nonpharmacological therapy in traditional Chinese medicine (TCM). However, whether acupuncture can effectively treat fibromyalgia is currently unclear. Therefore, we aim to design a study protocol of a randomized controlled clinical trial and assess the effectiveness of acupuncture for patients with fibromyalgia, which may lead to alleviation of clinical symptoms and improvement of patients’ quality of life.

Methods
The study is designed as a randomized, blinded, placebo-controlled trial of two cohorts conducted at Guang’anmen Hospital of China Academy of Chinese Medical Sciences and Shenzhen Traditional Chinese Medicine Hospital, respectively. A total of 68 patients with primary fibromyalgia, diagnosed with the American College of Rheumatology criteria, are randomly allocated with a 1:1 ratio to acupuncture or sham acupuncture groups. All subjects will receive acupuncture intervention for 8 weeks with follow-up assessments every 4 weeks for 16 weeks. The primary outcome will be evaluated using the visual analogue scale (VAS) and revised fibromyalgia impact questionnaire (FIQR) for pain intensity. The secondary outcome measures will include: Multidimensional Assessment of Fatigue scale (MAF), Short Form-36 (SF-36), Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), Chinese perceived stress scales (pss-14), changes in the number of 18 tender points, patient satisfaction for the treatment and adverse events. The mentioned outcome measurements will be assessed every 4 weeks for 6 months.

Discussion
This clinical trial will use advanced research methods to evaluate the efficacy and safety of acupuncture on fibromyalgia. The results of this trial may provide clinical evidence on the beneficial effects of acupuncture in treating fibromyalgia.

Influence of sampling schedules on [177Lu]Lu-PSMA dosimetry
Authors: Rinscheid Andreas , Kletting Peter , Eiber Matthias , Beer Ambros J. , Glatting Gerhard 
Published: June 2020

Abstract
Background
Individualized dosimetry is recommended for [177Lu]Lu-PSMA radioligand therapy (RLT) which is resource-intensive and protocols are often not optimized. Therefore, a simulation study was performed focusing on the determination of efficient optimal sampling schedules (OSS) for renal and tumour dosimetry by investigating different numbers of time points (TPs).

Methods
Sampling schedules with 1–4 TPs were investigated. Time-activity curves of the kidneys and two tumour lesions were generated based on a physiologically based pharmacokinetic (PBPK) model and biokinetic data of 13 patients who have undergone [177Lu]Lu-PSMA I&T therapy. Systematic and stochastic noise of different ratios was considered when modelling time-activity data sets. Time-integrated activity coefficients (TIACs) were estimated by simulating the hybrid planar/SPECT method for schedules comprising at least two TPs. TIACs based on one single SPECT/CT measurement were estimated using an approximation for reducing the number of fitted parameters. For each sampling schedule, the root-mean-squared error (RMSE) of the deviations of the simulated TIACs from the ground truths for 1000 replications was used as a measure for accuracy and precision.

Results
All determined OSS included a late measurement at 192 h p.i., which was necessary for accurate and precise tumour TIACs. OSS with three TPs were identified to be 3–4, 96–100 and 192 h with an additional SPECT/CT measurement at the penultimate TP. Kidney and tumour RMSE of 6.4 to 7.7% and 6.3 to 7.8% were obtained, respectively. Shortening the total time for dosimetry to e.g. 96 h resulted in kidney and tumour RMSE of 6.8 to 8.3% and 9.1 to 11%, respectively. OSS with four TPs showed similar results as with three TPs. Planar images at 4 and 68 h and a SPECT/CT shortly after the 68 h measurement led to kidney and tumour RMSE of 8.4 to 12% and 12 to 16%, respectively. One single SPECT/CT measurement at 52 h yielded good approximations for the kidney TIACs (RMSE of 7.0%), but led to biased tumour TIACs.

Conclusion
OSS allow improvements in accuracy and precision of renal and tumour dosimetry for [177Lu]Lu-PSMA therapy with potentially less effort. A late TP is important regarding accurate tumour TIACs.

Abstract
Background
Field triage of trauma patients is crucial to get the right patient to the right hospital within a particular time frame. Minimization of undertriage, overtriage, and interhospital transfer rates could substantially reduce mortality rates, life-long disabilities, and costs. Identification of patients in need of specialized trauma care is predominantly based on the judgment of Emergency Medical Services professionals and a pre-hospital triage protocol. The Trauma Triage App is a smartphone application that includes a prediction model to aid Emergency Medical Services professionals in the identification of patients in need of specialized trauma care. The aim of this trial is to assess the impact of this new digital approach to field triage on the primary endpoint undertriage.

Methods
The Trauma triage using Supervised Learning Algorithms (TESLA) trial is a stepped-wedge cluster-randomized controlled trial with eight clusters defined as Emergency Medical Services regions. These clusters are an integral part of five inclusive trauma regions. Injured patients, evaluated on-scene by an Emergency Medical Services professional, suspected of moderate to severe injuries, will be assessed for eligibility. This unidirectional crossover trial will start with a baseline period in which the default pre-hospital triage protocol is used, after which all clusters gradually implement the Trauma Triage App as an add-on to the existing triage protocol. The primary endpoint is undertriage on patient and cluster level and is defined as the transportation of a severely injured patient (Injury Severity Score ≥ 16) to a lower-level trauma center. Secondary endpoints include overtriage, hospital resource use, and a cost-utility analysis.

Discussion
The TESLA trial will assess the impact of the Trauma Triage App in clinical practice. This novel approach to field triage will give new and previously undiscovered insights into several isolated components of the diagnostic strategy to get the right trauma patient to the right hospital. The stepped-wedge design allows for within and between cluster comparisons.

Authors: Bromfield Michael , Profyris Christos , Mehtar Aadila , Du Toit Marna , Wadee Reubina 
Published: June 2020

Abstract
Background
Papillary tumor of the pineal region is an unusual, recently described entity with potential for misinterpretation as either an ependymoma or choroid plexus papilloma. With few reported cases, there is little data regarding the biologic behavior, natural course and optimal treatment for these patients. Further accumulation of reports will assist with defining this entity and may provide further insight into management of such patients.

Case presentation
This patient was a 24-year-old male with new onset seizures and a decreased level of consciousness. MRI scan showed a large heterogeneously enhancing solid-cystic mass in the pineal region extending to the third ventricle.

Discussion
Papillary tumor of the pineal region is a neuroepithelial tumor with distinct morphological and immunohistochemical features that can be utilized to help differentiate it from other primary and metastatic tumors occurring within this region. Although there is currently no clear consensus, the potential for disease progression and CSF dissemination supports early aggressive therapy in these patients.
Ultrastructure of the fertilized egg envelopes in Ancistrus cirrhosus, Loricariidae, Teleostei
Authors: Kim Dong Heui 
Published: June 2020

AbstractWe examined the morphology of fertilized egg and ultrastructures of fertilized egg envelopes of Ancistrus cirrhosus belong to Loricariidae using light and electron microscopes. The fertilized eggs formed a mass on the spawning place and were yellowish, spherical, non-transparent, demersal, adhesive, and a narrow perivitelline space. But, the adhesiveness of fertilized eggs was disappeared after spawning excluding contact parts. The micropyle with funnel shape was surrounded by 15–19 furrow lines of egg envelope in a spoke-like pattern. The outer surface of egg envelope has smooth side and inner surface of egg envelope was rough with grooves. Also, the total thickness of the fertilized egg envelope was about 32.58 ± 0.85 μm (n = 20), and the fertilized egg envelope consisted of three layers, an outer adhesive electron-dense layer, a middle layer with low electron density and an inner electron-dense layer with grooves in counter structure from other most teleost. Collectively, these morphological characteristics and adhesive property of fertilized egg, and ultrastructures of micropyle, outer surface, and section of fertilized egg envelope are showed species specificity.
