Authors: Enyew Mihretu Molla 
Published: June 2020

Abstract
Background: In developing countries, abortion is often unsafe and a signiﬁcant cause of maternal morbidity and mortality accounting for about 8% (4.7%–13.2%) of maternal mortality worldwide. Internationally, safe abortion services are recognized as reducing maternal mortality, and liberalized abortion laws are associated with reduced mortality resulting from unsafe abortion procedures. However, health care providers have moral, social and gender-based reservations that affects their willingness towards providing induced abortion services. The purpose of this study was to assess willingness to perform induced abortion and associated factors among graduating Midwifery, Medical, Nursing, and Public health officer students of University of Gondar. Methods: Institution based cross sectional study was conducted from March 29 to May 30, 2019. All graduating students available during data collection period were considered as study population. Stratified simple random sampling technique was used to select 424 study participants. Pre tested, semi- structured, self-administered questionnaire was used to collect data. Data analysis was done using SPSS version 20. Ethical clearance was obtained from School of midwifery under the delegation of institutional review board of university of Gondar.Results: 290 students out of 424 students were willing to perform induced abortion for indications supported by Ethiopian abortion law, making a proportion of 68.4% (95%Cl: 64.2, 72.9). Sex (Being male (AOR = 4.89, 95%CI: 3.02, 7.89)), religion (being orthodox than protestant (AOR = 10.41, 95%CI: 3.02, 21.57)), being Muslim than protestant (AOR = 5.73, 95%CI: 1.37, 15.92)) and having once or less a week religious attendance (AOR=2.00, 95% CI: 1.20, 3.34) were factors associated with willingness towards performing induced abortion.Conclusions: According to this study willingness of students towards providing induced abortion services was good. However female students, protestant followers and those students with more than once a week religious attendance should be encouraged in abortion care provisions.

Abstract
Background: Nan Ling commodity grain base is a national high-standard farmland demonstration area. Scientific evaluation of soil environmental quality is of important significance to plan land resources rationally to improve the quality and efficiency of agricultural production.Methods: This paper try to apply the equal intercept transformation radar chart --an improved radar chart--to the assessment of soil environmental quality. In the assessment, the area of equal intercept transformation radar chart is adopted to represents the soil environmental quality.Different from the other assessment methods in common use, the equal intercept transformation radar chart method, as a visual graphic data analysis method, transforms data into graphics and therefore the data information can be retained and excavated more fully. Moreover, this advanced radar chart overcomes targetedly the main defect of the conventional radar chart that the evaluation result depends heavily on the order of arrangement of indicators.Results: The results indicate that the soil environmental quality at depth of 0-60cm in low mountain area of Nan ling commodity grain base is the second grade while that in the hilly and plain area are both the first grade. The indicators of poor soil environmental quality in low mountain area are exogenous Cd and endogenous As, those in hilly area are exogenous Cd and endogenous As and Hg, and that in plain area is exogenous Cd.Conclusion: It is proved through this special case study that the application of equal intercept transformation radar chart to the assessment of soil environmental quality is feasible and more intuitive, comprehensive and fine.

Abstract
Background: Hypertrophic cardiomyopathy (HCM) is the most common inherited cardiovascular disease that affects approximately one in 500 people. HCM is a recognized genetic disorder most often caused by mutations involving myosin-binding protein C (MYBPC3) and β-myosin heavy chain (MYH7) which are responsible for approximately three-quarters of the identified mutations.Methods: As a part of the international multidisciplinary SILICOFCM project (www.silicofcm.eu) the present study evaluated the association between underlying genetic mutations and clinical phenotype in patients with HCM. Only patients with confirmed single pathogenic mutations in either MYBPC3 or MYH7 genes were included in the study and divided into two groups accordingly. The MYBPC3 group was comprised of 48 patients (76%), while the MYH7 group included 15 patients (24%). Each patient underwent clinical examination and echocardiography.Results: The most prevalent symptom in patients with MYBPC3 was dyspnea (44%), whereas in patients with MYH7 it was palpitations (33%). The MYBPC3 group had a significantly higher number of patients with a positive family history of HCM (46% vs. 7%; p=0.014). There was a numerically higher prevalence of atrial fibrillation in the MYH7 group (60% vs. 35%, p=0.085). Laboratory analyses revealed normal levels of creatinine (85.5±18.3 vs. 81.3±16.4 µmol/l; p=0.487) and blood urea nitrogen (10.2±15.6 vs. 6.9±3.9 mmol/l; p=0.472) which were similar in both groups. The systolic anterior motion presence was significantly more frequent in patients caring MYH7 mutation (33% vs. 10%; p=0.025), as well as mitral leaflet abnormalities (40% vs. 19%; p=0.039). Calcifications of mitral annulus were registered only in MYH7 patients (20% vs. 0%; p=0.001). The difference in diastolic function, i.e. E/e’ ratio between the two groups was also noted (MYBPC3 8.8±3.3, MYH7 13.9±6.9, p=0.079).Conclusions: Major findings of the present study corroborate the notion that MYH7 gene mutation patients are presented with more pronounced disease severity than those with MYBPC3.

Abstract
Background: Achieving optimal abdominal analgesia with few side effects is the goal of pain management after cesarean delivery. Intrathecal morphine is the current standard but ultrasound guided quadratus lumborum block (US-QLB) may offer superior pain control with fewer side effects. This study compared the pain-free period after cesarean delivery among parturients who received spinal block with IT morphine 0.2 mg, with IT morphine 0.2 mg and bilateral QLB, or only bilateral QLB.Methods: Parturients having elective cesarean delivery with a low transverse incision under spinal block were randomized to three groups. Subjects were allocated into IT morphine 0.2 mg with sham QLB (Group IT morphine), IT morphine 0.2 mg and bilateral QLB with 0.25% bupivacaine 25 ml and adrenaline 1:250,000 in each side (Group IT morphine with QLB), or bilateral QLB with 0.25% bupivacaine 25 ml and adrenaline 1:250,000 in each side (Group QLB). A PCA pump was connected to each parturient after completion of the QLB or sham block. The first time to PCA morphine requirement when parturients experienced pain was recorded and compared.Results: Eighty parturients were included. Analysis of Group QLB was terminated early because Kaplan-Meier survival analysis showed the median pain-free period to be significantly shorter in Group QLB at the second interim analysis; [2.50 hours (95% CI: 1.04-3.96) in Group IT morphine vs. 7.75 (95% CI: 5.67-9.83) in Group IT morphine with QLB vs. 1.75 (95% CI: 0.75-2.75) in Group QLB (overall p<0.001)]. The median (min, max) amount of morphine required during 24 hours was 5.5 (0-25) in Group IT morphine vs. 5.0 (0-36) in Group IT morphine with QLB vs. 17.5 (1-40) mg in Group QLB (p<0.001). In the final analysis the median pain-free period was 2.50 hours (95%CI: 1.23-3.77) in Group IT morphine (n=27) and 8.02 (95%CI: 5.96-10.07) in Group IT morphine with QLB (n=28). (Gehan-Breslow p=0.027).Conclusion: US-QLB used in conjunction with IT morphine yielded a statistically significant longer median pain-free period compared with standard IT morphine alone. However, QLB alone provided inferior pain control compared with standard IT morphine. When combined with IT morphine, QLB may provide additional analgesic benefit as a part of multimodal analgesic regimen, especially during the early postoperative period.Trial registration: ClinicalTrials.gov no.

Abstract
Background: Hepatocellular carcinoma (HCC) ranks the fourth in terms of cancer-related mortality globally. Herein, in this research, we attempted to develop a novel immune-related gene signature that could predict survival and efficacy of immunotherapy for HCC patients.Methods: The transcriptomic and clinical data of HCC samples were downloaded from The Cancer Genome Atlas (TCGA) and GSE14520 datasets, followed by acquisition of immune-related genes from the ImmPort database. Afterwards, an immune-related gene-based prognostic index (IRGPI) was constructed using the Least Absolute Shrinkage and Selection Operator (LASSO) regression model. Kaplan-Meier survival curves as well as time-dependent receiver operating characteristic (ROC) curve were performed to evaluate its predictive capability. Besides, both univariate and multivariate analysis on overall survival for the IRGPI and multiple clinicopathologic factors were carried out, followed by the construction of nomogram. Finally, we explored the possible correlation of IRGPI with immune cell infiltration or immunotherapy efficacy. Results: Analysis of 365 HCC samples identified 11 differentially expressed genes, which were selected to establish the IRGPI. Notably, it can predict survival of HCC patients more accurately than published biomarkers. Furthermore, IRGPI can predict the infiltration of immune cells in the tumor microenvironment of HCC, as well as the response of immunotherapy.Conclusion: Collectively, the currently established IRGPI can accurately predict survival, reflect the immune microenvironment, and predict the efficacy of immunotherapy among HCC patients.

Abstract
Background: Recent genomic analyses revealed that druggable molecule targets could only be detected in around 6% of nasopharyngeal carcinoma (NPC) patients. Yet, an addiction to dysregulated CDK4/6-cyclinD1 signalling pathway is an essential event in the pathogenesis of NPC. Using our newly established xenografts and cell lines derived from primary, recurrent and metastatic NPC, we aimed to evaluate the therapeutic efficacy of a specific CDK4/6 inhibitor, palbociclib, and its compatibility with other chemodrugs in treating NPC.Methods: The efficacy of single treatment of palbociclib on NPC models was first evaluated, followed by concurrent treatment with cisplatin or suberanilohydroxamic acid (SAHA). RNA sequencing was used to profile the related pathways in governing the drug response. Palbociclib-resistant NPC cell lines were also established to demonstrate if cisplatin could be used as a second-line treatment once the cells developed resistance to palbociclib. The efficacy of palbociclib treatment on cisplatin-resistant NPC cells was also examined. Results: Palbociclib single drug treatment was confirmed to have a cell cycle arresting effect of NPC cells in G1 phase in vitro. It also had a significant inhibitory effect in all the 6 NPC tumor models in vivo, with a substantial reduction in total tumor volume and proliferation marker Ki-67. Concurrent use of palbociclib dampened the cytotoxic effect of cisplatin in NPC cells in vitro. Notably, combination of palbociclib with SAHA resulted in synergistic cell death of NPC both in vitro and in vivo. Autophagy-associated cell death was found to be involved in the enhanced tumor growth inhibitory effect in the combined palbociclib+SAHA treatment. NPC cell lines trained to sustain growth in high dose of palbociclib and cisplatin remained sensitive in subsequent treatment of cisplatin or palbociclib respectively.Conclusions: This study provides essential evidences to position palbociclib as an alternative therapeutic option to NPC treatment, and to aware the effective administrative timing of palbociclib with other chemodrugs. The findings give the basis for planning of the first-in-human clinical trials of palbociclib regimens in NPC patients.

Abstract
Background: DNA repair genes play a vital role in the treatment of many cancers, and DNA repair genes can be used in breast cancer recurrence and metastasis research. We found that the expression of DNA repair genes in breast cancer patients after recurrence and metastasis is abnormal, however, the clinical predictive significance of DNA repair genes is still elusive. Methods: The nested case-control method was used in patients with breast cancer recurrence and metastasis after surgery (n=109) and patients without recurrence and metastasis after surgery (n=109). The proteins and mRNA of DNA repair genes were detected by immunohistochemistry and Real-time PCR respectively. Results: PARP1(OR=1.485, 95%CI:1.279~1.725, P<0.05), XRCC4(OR= 1.419, 95%CI:1.217~ 1.656, P<0.05) and ERCC1 (OR=1.181, 95%CI: 1.032~1.353, P<0.05) were risk factors for postoperative recurrence and metastasis of breast cancer. Therefore, we used the ROC curve to study the optimal critical values of PARP1, XRCC4, and ERCC1, combined with the comprehensive judgment of clinical experience, we can conclude that PARP1 (cutoff value = 6, Se = 75.23%, Sp = 79.82%), XRCC4 (cutoff value = 6, Se = 78.9%0, Se = 79.82%), ERCC1 (cutoff value = 3, Se = 89.91%, Sp = 47.71%), suggesting that when the PARP1 score is higher than 6 or the XRCC4 score is higher than 6 or the ERCC1 score is higher than 3, the risk of recurrence and metastasis will increases (ORPARP1 = 14.941, 95% CIPARP1: 4.004~55.758, P <0.05; ORXRCC4 = 16.740, 95% CIXRCC4: 6.433 ~ 43.560, P <0.05; ORERCC1 = 5.285, 95% CIERCC1: 1.843 ~ 15.156, P <0.05). Due to PARP1, ERCC1 and XRCC4 belong to a part of DNA repair gene system, and the three proteins are positively correlated by correlation analysis (rPARP1-ERCC1=0.317; rPAPR1-XRCC4=0.329; rERCC1-XRCC4=0.377). The combined diagnosis of the PARR1,ERCC1 and XRCC4 have greater predictive value for the risk of recurrence and metastasis of breast cancer(Se = 88.99%, Sp = 82.57%；OR = 50.914, 95% CI: 10.918, 237.417, P <0.05).Conclusions: The recurrence and metastasis of breast cancer are predictive after PARP1>6, XRCC4>6, and ERCC1>3. The combined diagnosis of the three indicators have greater predictive value for the risk of recurrence and metastasis of breast cancer.

Abstract
Background
Breed specific reference ranges for selected blood parameters are recommended for proper interpretation of blood tests, but there are only few reports dealing with ponies. The purpose of this study was to investigate if blood parameters differ among ponies’ classes and to check if general normal values for equine species are applicable to ponies.
Results
All, except total protein concentration, biochemical parameter significantly (p < 0.05) differed among ponies’ classes. The most pronounced difference was noted in blood lactate concentrations, higher (p < 0.001) in the smallest ponies (class A). In all groups of ponies muscle enzymes (aspartate aminotransferase and creatine kinase) and urea were high when compared to normal values for equine species, but triglycerides and creatinine were low. Blood lactate concentration was high in comparison with normal values for horses only in class A ponies’.
Conclusions
In healthy ponies, blood lactate concentration significantly differs between height classes. Normal values for equine species should not be directly applied to interpret the lactate, triglycerides, aspartate aminotransferase and creatine kinase values in ponies.

Published: June 2020

Abstract
Background: Self-efficacy is developed through a person’s interaction with his/her physical and social environment. Self-efficacy in caring is an essential attribute of care workers to develop a positive attitude towards their clients, improve work performance, and enhance job satisfaction. Care workers’ self-efficacy may vary according to the context in which the care is being provided. Aged care is a multidimensional and challenging setting, and characteristics of aged care services are different from those of acute care services. The objective of this review is to give an overview of the self-efficacy of residential aged care workers in caring for older people and factors influencing their self-efficacy. Methods: The protocol for this review is based on the Joanna Briggs Institute Reviewer's Manual for Scoping Review. A systematic search of the literature on electronic databases MEDLINE, PsycINFO, CINAHL, AgeLine, SCOPUS, and ProQuest Dissertations and Theses Global will be carried out using predefined search terms to identify relevant studies. This review will include studies that examined the self-efficacy of direct care workers in caring for older people living in residential aged care facilities. All primary studies irrespective of the study design will be included. Studies conducted to develop measures or studies with informal care workers or students as study participants will not be considered. Two reviewers will independently conduct title and abstract screening, full-text screening, and data charting. A third reviewer will resolve discrepancies, while the final decision for conflicting studies will be made by consensus within the review team. Descriptive statistics will be utilised to analyse the quantitative findings and the result will be presented in narrative form accompanied by tables and charts. Content analysis will be carried to analyse the qualitative findings and will be presented in narrative form supported by illustrative quotations. Discussion: This study will be an important source of knowledge to policymakers and aged care providers to understand the self-efficacy of aged care workers to support and enhance their self-efficacy and thereby improve their caring behaviours towards their clients.Scoping review registration: Joanna Briggs Institute Systematic Review Register with the title ‘A scoping review of factors influencing caring efficacy of direct care workers providing care to older people’

Published: June 2020

Abstract
Background: Non-intubated thoracoscopic lung surgery has been widely applied as it is technically feasible and safe. Spontaneous rupture of the esophagus, also known as Boerhaave's syndrome (BS), is rare after chest surgery.Case Presentation: A 60-year-old female non-smoker underwent non-intubated uniportal thoracoscopic wedge resection assisted with a laryngeal mask for a solitary pulmonary nodule. Ultrasound-guided serratus anterior plane block was utilized for analgesia. The patient complained of hyperemesis followed by chest pain and acute dyspnea 6 hours after the surgery. Emergency chest x-ray revealed the right-sided hydropneumothorax. BS was confirmed by further chest tube drainage and computed tomography. The patient refused surgical intervention; therefore, conservative procedures including pleural evacuation through a naso-leakage drainage tube, antibiotics and tube feeding were administered. The healing of the esophagus was recorded 40 days later.Conclusions: Perioperative antiemetic is an indispensable item of tubeless thoracic surgery. BS should be kept in mind when the patients suffer from sudden chest distress following severe vomiting after tubeless lung surgery.

Abstract
Background: Breast cancer is rare in men and there is no report of male breast cancer (MBC) with ureteral metastasis. In this study, we report a special case of MBC with ureteral metastasis. Case presentation: A 60-year-old man was diagnosed with breast cancer and lymph nodes metastasis. After surgery, chemotherapy and radiotherapy he was diagnosed with left arm metastasis. Then he received mass dissection and chemotherapy again. He was diagnosed with ureter metastasis because of hematuria. This patient took a Precitype gene test (immune index and PAM50) after several lines of treatment and the result indicated that this was a Luminal A subtype case, which was quite different from his immunohistochemical subtype. We adjusted his therapeutic regimen according to the genetic test but there was no obvious efficacy and he passed away five months later. Conclusions: MBC patients with urinary symptoms should be considered for the possibility of metastasis although urinary metastasis in breast cancer is rare. We still need more research and evidence of treatment recommendations for MBC.
