Published: August 2020

Abstract
Background: Ethiopia is one of the nations which has an enormous burden of intimate partner violence (IPV), and where it is usually difficult to talk about HIV separately from IPV. Objectives: This research aimed to explore the lived experience of IPV against women using antiretroviral therapy (ART) and other outpatient services in Wolaita Zone, Ethiopia Methods: We used an Interpretive (hermeneutic) Phenomenological Analysis design among purposively selected adult women aged 18-49 years. A total of 43 women participated in this study, of whom 30 were using ART, and 13 women were using other health services. We used an in-depth interview and focus group discussions until data saturation, while conscious of the need to maintain the scientific rigor, dependability, and credibility. The data were transcribed verbatim and translated into English. We read the transcripts repeatedly to understand the content. We used NVivo 11 software to assist with data organisation, and also, we used the framework analysis method. Results: We identified five themes, namely: “women's terrifying experiences of violence,” “the effect of violence on women's health,” “support/lack of support /partner’s controlling behaviours,” “women’s feelings about the available services,” and “IPV prevention strategies from the perspective of women.” Interviewees described their violent experiences which included wife-beating, being stigmatised in front of others, having material thrown at the woman’s face, wife’s hand and teeth were broken, forced sex, restriction of movement, name-calling, threats to hurt, being insulted, being left alone, and the withdrawal of finances. The negative health impacts reported included abortion, infection with HIV and other sexually transmitted diseases, disability, child’s death, and depression. The disclosure of HIV test information resulted in violence. Inappropriate punishment of the perpetrator and the lack of a supportive women’s network to avert IPV were perceived as legal limitations Conclusions: IPV is a considerable health burden, varying in its presentation and its negative impact on women’s health. Improved laws should provide justice for all victims. Establishing a women’s network to assist women at risk of violence, should be emphasised. Unwise HIV test result disclosure leads to IPV; hence HIV disclosure should be facilitated through health care providers.

Abstract
Background: The clinical clerkship is a crucial stage in nursing training, yet a dissatisfaction at this stage may cause a nurse to quit in future. This study aimed to investigate the relationship among personality dimensions, spirituality, coping strategies and clinical clerkship satisfaction among intern nursing students. Methods: This was a correlational, cross-sectional study. A total of 293 Iranian nursing students, who were fulfilling their clinical clerkship at university-affiliated hospitals in Tehran, were selected using cluster random sampling. All participants were provided with standard questionnaires including personality dimensions (NEO_FFI), spirituality, coping strategies (WoCQ), and satisfaction with clinical clerkship. Data were analyzed using Pearson correlation and hierarchical multiple regression. Results: The results showed that spirituality (β=0.32, p<0.001), problem-focused coping (β=0.26, p<0.001) and extraversion (of personality dimensions, β=0.22, p<0.001) played significant roles in predicting clinical clerkship satisfaction among intern nursing students. Regression analysis showed openness (β=0.14, p<0.01), extraversion (β=0.16, p<0.01), and spirituality (β=0.23, p<0.001) could significantly predict problem-focused coping style among intern nursing students. However, personality dimensions and spirituality were not good predictors for emotion-focused coping among these students (p>0.05). Conclusion: Personality dimensions, coping strategies and, in particular, spirituality are good predictors of clinical clerkship satisfaction among intern nursing students. Therefore, paying attention to spiritual needs in nursing students, improving their problem solving skills in dealing with clinical stress and training extraversion characteristics can be effective in enhancing their satisfaction with clinical clerkship.

Abstract
We developed a novel auto-nucleation suppressed mechanism (ANSM) for direct synthesis of EM-visible gold nanoparticles (AuNPs) on cysteine-rich tags (e.g., metallothionein) in cells for single-molecule detection with electron microscopy (it accompanies our Nature Method manuscript, Jiang et al. 2020 [1]). Both tagged-fusion proteins expressed in cells (e.g.bacteria, yeast and mammalian cells) and antigens stained with antibody-tag fusion proteins can be visualized by this protocol. Here we describe the typical protocols (both the chemical fixation and the high pressure freezing cases) developed for ANSM-based AuNP synthesis in HeLa cells expressing metallothionein (MTn) tags (Figure 1). This approach should be widely applicable to many systems for EM visualization of single-molecule in mammalian cells.
Influence of cannabis exposure in pregnancy on childhood health outcomes: a population-based birth cohort
Authors: Corsi Daniel J , Hsu Helen , El-Chaar Darine , Fell Deshayne , Walker Mark 
Published: August 2020

Abstract
Cannabis use in pregnancy has increased, and many women continue to use it throughout pregnancy. With the legalization of recreational cannabis in many jurisdictions, there is concern about potentially adverse childhood outcomes related to prenatal exposure.4 Using the provincial birth registry containing information on cannabis use during pregnancy, we will assemble a large, population-based cohort of children born to mothers in Ontario, with and without prenatal exposure to cannabis from birth to 10 years of age. A series of investigations will examine the health effects of prenatal cannabis exposure on child outcomes using novel methods to address confounding. We will link pregnancy and birth data to provincial health administrative databases to ascertain child neurodevelopmental outcomes. The unique aspect of our proposed research is that we plan to utilize an existing population-based perinatal registry combined with administrative datasets for long-term follow up of children using a rich set of covariates and potential confounders to assess the association with cannabis exposure on pregnancy and perinatal outcomes and into childhood.
Mitochondrial DNA drives noncanonical inflammation activation via cGAS–STING signaling pathway in retinal microvascular endothelial cells
Authors: Guo Yue , Gu Ruiping , Gan Dekang , Hu Fangyuan , Li Gang , Xu Gezhi 
Published: August 2020

Abstract
Background

Pathological stimuli cause mitochondrial damage and leakage of mitochondrial DNA (mtDNA) into the cytosol, as demonstrated in many cell types. The cytosolic mtDNA then drives the activation of noninfectious inflammation. Retinal microvascular endothelial cells (RMECs) play an important role in the inner endothelial blood–retinal barrier (BRB). RMEC dysfunction frequently occurs in posterior-segment eye diseases, causing loss of vision. In this study, we investigated the involvement of cytosolic mtDNA in noninfectious immune inflammation in RMECs under pathological stimuli.

Methods

RMECs were stimulated with 100 ng/ml lipopolysaccharide (LPS), 200 μM hydrogen peroxide (H 2 O 2 ), or 25 mM d -glucose. After 24 h, immunofluorescent staining was used to detect the opening of the mitochondrial permeability transition pore (MPTP). Cytosolic mtDNA was detected with immunofluorescent staining and PCR after stimulation. mtDNA was then isolated and used to transfect RMECs in vitro, and the protein levels of cGAS were evaluated with western blotting. Real-time PCR was used to examine cGAS mRNA expression levels at different time points after mtDNA stimulation. The activation of STING was detected with immunofluorescent staining 6 h after mtDNA stimulation. Western blotting was used to determine the expression of STING and IFNβ, the phosphorylation status of TBK1, IRF3, and nuclear factor-κB (NF-κB) P65, and the nuclear translocation of IRF3 and NF-κB P65 at 0, 3, 6, 12, and 24 h. The mRNA expression of proinflammatory cytokines CCL4, CXCL10, IFNB1, and transcription factor IRF1 were determined with real-time PCR, together with the concentrations of intercellular adhesion molecule 1 (ICAM-1) mRNA.

Results

Pathological stimuli caused mtDNA to leak into the cytosol by opening the MPTP in RMECs after 24 h. Cytosolic mtDNA regulated the expression of cGAS and the distribution of STING in RMECs. It promoted ICAM-1, STING, and IFNβ expression, TBK1, IRF3, and NF-κB phosphorylation and the nuclear translocation in RMECs at 12 and 24 h after its transfection. The mRNAs of proinflammatory cytokines CCL4, CXCL10, IFNB1, and transcription factor IRF1 were significantly elevated at 12 and 24 h after mtDNA stimulation.

Conclusions

Pathological stimulation induces mtDNA escape into the cytosol of RMECs. This cytoplasmic mtDNA is recognized by the DNA sensor cGAS, increasing the expression of inflammatory cytokines through the STING–TBK1 signaling pathway.
Impact of cervical sagittal parameters on axial neck pain in patients with cervical kyphosis
Authors: Li Jia , Zhang Di , Shen Yong 
Published: August 2020

Abstract
Background: Cervical sagittal alignment (CSA) is closely related with cervical disc degeneration and impacts the spinal function, especially in the setting of cervical kyphosis (CK). In this study, we evaluated the influence of cervical sagittal parameters on the development of axial neck pain (ANP) in patients with CK.Methods: Data pertaining to 263 patients with CK who visited the outpatient department of our hospital between January 2012 and December 2018 were retrospective analyzed. The most common symptoms of ANP were neck pain, stiffness, or dullness. Visual analogue scale (VAS) was used to evaluate ANP. The following radiographic parameters were evaluated: CK types, C2-7 sagittal vertical axis (SVA), thoracic inlet angle (TIA), T1 slope, neck tilt (NT), cranial tilt, and cervical tilt. Sagittal alignment of CK was classified into 2 types: global and regional type. Multivariate logistic regression analysis was performed to identify risk factors for ANP.Results: Patients who complained of ANP were categorized as ANP group (VAS score≥3; n=92), while those without ANP were categorized as non-ANP group (VAS score<3; n=171). There was no significant between-group difference with respect to age (P=0.196), gender (P=0.516), TIA (P=0.139), NT (P=0.676), CK type (P=0.533), cranial tilt (P=0.332), cervical tilt (P=0.585), or cervical disc degeneration (P=0.695). The T1 slope and C2-7 SVA in the ANP group was significantly greater than that in the non-ANP group (P < 0.05). On multivariate logistic regression, C2-7 SVA [odds ratio (OR) 2.318, 95% confidence interval 1.373–4.651, P=0.003) and T1 slope (OR 2.563, 95% CI 1.186–4.669, P=0.028) were identified as risk factors for ANP.Conclusions: Our findings suggest a significant effect of cervical sagittal parameters on the occurrence of ANP in patients with CK. Greater T1 slope and larger C2-7 SVA may lead to the development of neck pain.

Published: August 2020

Abstract
Background Recovery of motor dysfunction is important for patients with incomplete cervical spinal cord injury (SCI). To enhance the recovery of muscle strength, both research and treatments mainly focus on injury of upper motor neurons at the direct injury site. However, accumulating evidences have suggested that SCI has a downstream effect on the peripheral nervous system, which may contribute to the poor improvement of the muscle strength after operation. The aim of this study is to investigate the impact of early vs. delayed surgical intervention on the lower motor neurons (LMNs) distal to the injury site in patients with incomplete cervical SCI. Methods Motor unit number index (MUNIX) was performed on the tibialis anterior (TA), extensor digitorum brevis (EDB) and abductor hallucis (AH) in 47 patients with incomplete cervical SCI (early vs. delayed surgical-treatment: 17 vs. 30) and 34 healthy subjects approximately 12 months after operation. All patients were further assessed by American spinal injury association (ASIA) motor scales and Medical Research Council (MRC) scales. Results There are no difference of both ASIA motor scores and MRC scales between the patients who accepted early and delayed surgical treatment (P > 0.05). In contrast, the patients undergoing early surgical treatment showed lower MUSIX values in both bilateral EDB and bilateral TA, along with greater MUNIX values in both right-side EDB and right-side TA, compared to the patients who accepted delayed surgical treatment (P < 0.05). Conclusions Cervical SCI has a negative effect on the LMNs distal to the injury site. Early surgical intervention in Cervical SCI patients may improve the dysfunction of LMNs distal to the injury site, reducing secondary motor neuron loss, and eventually improving clinical prognosis.

Abstract
Background

The positive response and the clinical usefulness of 14 serum antibodies in patients with esophageal squamous cell carcinoma (ESCC) were examined in this study. The Cancer Genome Atlas (TCGA) was used to investigate the frequency of gene expressions, mutations, and amplification of these 14 antigens and also the possible effects of antibody induction.

Methods

Blood serum derived from 85 patients with ESCC was collected and analyzed for the 14 antibodies using ELISA. The prognosis between positive and negative antibodies were then compared. The antibody panel included galectin1, HCA25a, HCC-22-5, and HSP70.

Results

Patient serum was positive for all antibodies, except VEGF, with the positive rates ranging from 1.18% to 10.59%. Positive rates for galectin1, HCA25a, HCC-22-5, and HSP70 were >10%. TCGA data revealed that all antigen-related genes had little or no mutation or amplification, and hence an increase in gene expression affected antibody induction. The positive results from the panel accounted for the positive rate comparable to the combination of CEA and SCC. No significant association was observed between the presence of antibodies and disease prognosis.

Conclusions

The detection rates of galectin1, HCA25a, HCC-22-5, and HSP70 were 10% higher in patients with ESCC. Gene overexpression may be involved in such antibody production. These four antibodies were applied as a panel in comparison with conventional tumor markers. Moreover, it was confirmed that the combination of this panel and the conventional tumor markers significantly improved the positive rate.
Going web or staying paper? The use of web-surveys among older people
Authors: Kelfve Susanne , Kivi Marie , Johansson Boo , Lindwall Magnus 
Published: August 2020

Abstract
Background: Web-surveys are increasingly used in population studies. Yet, web-surveys targeting older individuals are still uncommon for various reasons. However, with younger cohorts approaching older age, the potentials for web-surveys among older people might be improved. In this study, we investigated response patterns in a web-survey targeting older adults and the potential importance of offering a paper questionnaire as an alternative to the web questionnaire.

Methods: We analyzed data from three waves of a retirement study, in which a web-push methodology was used and a paper questionnaire was offered as an alternative to the web questionnaire in the last reminder. We mapped the response patterns, compared web- and paper respondents and compared different key outcomes resulting from the sample with and without the paper respondents, both at baseline and after two follow-ups.

Results: Paper-respondents, that is, those that did not answer until they got a paper questionnaire with the last reminder, were more likely to be women, low educated, fully retired, non-married and reported higher depression and lower self-rated health, compared with web-respondents. The association between retirement status and depression was only present among web-respondents. The differences between web and paper respondents were stronger in the longitudinal sample (after two follow-ups) than at baseline.

Conclusions: We conclude that a web survey might be a feasible and good alternative in surveys targeting people in the retirement age range. However, without offering a paper questionnaire, a small but important group will likely be missing with potential biased estimates as the result.

Published: August 2020

Abstract
BackgroundThe goal of this study is to disclose the clinically significant genomic alterations in patients with intrahepatic cholangiocarcinoma of the Chinese and Western populations.MethodsA total of 86 Chinese patients were enrolled in this study. Samples from those patients were sequenced for a panel of pan-cancer genes. Results were compared to a public dataset from a cohort of Western patients. The comparison between the two populations was conducted in the driver genes, actionability, and tumor mutational burden.ResultsThe Chinese and Western cohorts had 36 and 12 driver genes, respectively. Seven driver genes ( IDH1 , KRAS , TP53 , BAP1 , PBRM1 , ARID1A, and NRAS ) were shared by the two cohorts. For both cohorts, half of the patients had actionable mutations. The two cohorts shared most of the actionable genes but differed much in the frequency. Though KRAS mutations were at the first and second actionable rank respectively for Chinese and Western populations, they were still at a relatively low level of actionable evidence. Four driver genes ( SPTA1 , ARID2 , TP53 , and GATA1 ) were found significantly correlated with the tumor mutational burden.ConclusionsThe revealed genomic alterations with clinical significance could help to improve the treatment of intrahepatic cholangiocarcinoma.

Abstract
Background: To find agreement between the calculated intraocular lens (IOL) power from using the SRK/T based preoperative biometry and the intraoperative wavefront aberrometry (ORA®) in Thai cataract patients, and to compare the accuracy of each method with the postoperative refraction results.Methods: Eyes that underwent cataract surgery with monofocal or multifocal IOL implantation were enrolled in this prospective study. All eye biometry was measured preoperatively and the ORA intraoperatively. The SRK/T suggested IOL from the preoperative biometry was chosen in all cases. The suggested power and the estimated refraction (EST) from both devices were collected. Bland Altman analysis was used to find the agreement between them. The predicted EST of implanted IOL from both devices were compared with the one-month postoperative SE. Results: The study comprised 97 eyes (79 patients). Of these, 38 eyes (39.2%) had the same suggested IOL power, 36 eyes (37.1%) were within ±0.5D, 20 eyes (20.6%) were within ±1.0D and 3 eyes were beyond ±1.0D. Bland-Altman analysis found the mean difference between IOL power calculated from both devices was 0.39 with LoA of -0.54 to 1.31. The correlation was 98.50% (95%CI 98%- 99.10%). In the same suggested IOL power group, the median difference of EST by preoperative biometry and ORA compared with one-month postoperative SE were -0.08 (95%CI: -0.08, 1.11), and -0.14 (95%CI: -0.88, 1.2), respectively. Conclusions:The ORA and preoperative biometry results were in concordance with each other. The result of preoperative biometry was more accurate than ORA in this study.

Abstract
Background: Despite widespread use of femoral-sourced allografts in clinical spinal fusion procedures and the increasing interest in using femoral reamer–irrigator–aspirator (RIA) autograft in clinical bone grafting, few studies have examined the efficacy of femoral grafts compared to iliac crest grafts in spinal fusion. The objective of this study was to directly compare the use of autologous iliac crest with syngeneic femoral and iliac allograft bone in the rat model of lumbar spinal fusion.Methods: Single-level bilateral posterolateral intertransverse process lumbar spinal fusion surgery was performed on Lewis rats divided into three experimental groups: iliac crest autograft; syngeneic iliac crest allograft; and syngeneic femoral allograft bone. Eight weeks postoperatively, fusion was evaluated via microCT analysis, manual palpation and histology. In vitro analysis of the colony-forming and osteogenic capacity of bone marrow cells derived from rat femurs and hips was also performed to determine whether there was a correlation with the fusion efficacy of these graft sources.Results: Although no differences were observed between groups in CT fusion mass volumes, iliac allografts displayed an increased number of radiographically fused fusion masses and a higher rate of bilateral fusion via manual palpation. Histologically, hip-derived grafts showed better integration with host bone than femur derived ones, likely associated with the higher concentration of osteogenic progenitor cells observed in hip-derived bone marrow. Conclusions: This study demonstrates the feasibility of using syngeneic allograft bone in place of autograft bone within inbred rat fusion models and highlights the need for further study of femoral-derived grafts in fusion.
