Abstract
BackgroundIntrahepatic cholestasis of pregnancy (ICP) is a liver disorder that specifically occurs in pregnancy. Elevated levels of liver transaminases aspartate aminotransferase, alanine aminotransferase and serum bilirubin levels are common biochemical characteristics in ICP. The disorder is associated with an increased risk of premature delivery and stillbirth. The characterization of the potential microbiota in ICP could go a long way in the prevention and treatment of this pregnancy disease.MethodsA total of 58 patients were recruited for our study: 27 ICP patients and 31 healthy pregnant subjects with no ICP. The V3 and V4 regions of the 16S rDNA collected from fecal samples of both diseased and control groups were amplified. 16S rRNA gene amplicon sequencing was then performed on gut microbiota. Sequencing data were analyzed and the correlation between components of microbiota and patient ICP status was found. Related metabolic pathways, relative abundance and significantly different OTUs (Operational Taxonomic Units) between ICP and controls were also identified.ResultsElevated levels of total bile acid, ALT, AST, Dbil and Tbil were recorded or observed in ICP subjects as compared to the control. Gut microbiota in pregnant women was dominated by four major phyla and 27 core genera. PCoA analysis results indicated that there was no significant clustering in Bray-Curtis distance matrices. Our results showed that there was a correlation between specific OTUs and measured clinical parameters of pregnant women. Comparison at the different taxonomy levels revealed high levels of abundance of Blautia and Citrobacter in ICP patients. At the family level, Enterobacteriaceae and Leuconostocaceae were higher in ICP patients. 638 KEGG Orthologs and 138 pathways significantly differed in the two groups. PLS-DA model with VIP plots indicated a total of eight genera and seven species were key taxa in ICP and control groups.ConclusionsOur research indicated that although there was no significant clustering by PCoA analysis, patients with ICP have increased rare bacteria at different phylogenetic levels. Our results also illustrated that all 638 KEGG Orthologs and 136 in 138 KEGG pathways were less abundant in ICP patients compared to the controls.
Routinely collected patient data in neurology research: A systematic mapping review
Authors: Biggin Frances , Emsley Hedley , Knight Jo 
Published: October 2020

Abstract
Background This review focuses on neurology research which uses routinely collected data. The number of such studies is growing alongside the expansion of data collection. We aim to gain a broad picture of the scope of how routine healthcare data have been utilised. Methods This study follows a systematic mapping review approach which does not make a judgement on the quality of the papers included in the review, thereby enabling a complete overview of the field. Results Of 4481 publications retrieved, 386 met the eligibility criteria for this study. These publications covered a wide range of conditions, but the majority were based on one or only a small number of neurological conditions. In particular, publications concerned with three discrete areas of neurological practice - multiple sclerosis (MS), epilepsy/seizure and Parkinson’s disease - accounted for 60% of the total. MS was the focus of the highest proportion of eligible studies (35%), yet in the recent Global Burden of Neurological Disease study it ranks only 14th out of 15 neurological disorders for DALY rates. In contrast, migraine is the neurological disorder with the highest ranking of DALYs globally (after stroke) and yet it was represented by only 4% of eligible studies. Conclusion This review shows that there is a disproportionately large body of literature pertaining to relatively rare disorders, and a correspondingly small body of literature describing more common conditions. Therefore, there is potential for future research to redress this balance.

Abstract
Background: The current evidence about anemia and iron deficiency anemia (IDA) during pregnancy remains elusive in China. The purpose of this study is to investigate the prevalence of anemia and IDA and their risk factors in Chinese pregnant women.Methods: A nationwide cross-sectional survey of pregnant women was conducted during their antenatal visits. Using a multi-stage sampling method, 24 hospitals from 16 provinces across China were selected. Structured questionnaires were administered to collect information from participants and to extract clinical data from electronic medical records. Mixed-effects logistic regression models were performed to determine the risk factors associated with anemia and IDA.Results: In total, 12,403 pregnant women were enrolled, including 1,018 (8.2%) at the first trimester, 3,487 (28.1%) at the second, and 7,898 (63.7%) at the third. Overall, 19.8% of women were diagnosed with anemia and 13.9% were diagnosed with IDA. The prevalence of anemia and IDA varied among regions and increased by gestational month, peaking at the eighth gestational month (24.0% for anemia and 17.8% for IDA). Pregnant women at advanced stage of gestation, non-local residents, multiple gestations, multiparity, pre-pregnancy underweight, and those experiencing severe nausea or vomiting during pregnancy, were associated with higher risks of anemia and IDA.Conclusions: The prevalence of anemia and IDA during pregnancy are similar to those from developed countries and vary across regions in China.

Abstract
Background: High resolution 2D whole slide imaging provides rich information about the tissue structure. This information can be a lot richer if these 2D images can be stacked into a 3D tissue volume. A 3D analysis, however, requires accurate reconstruction of the tissue volume from the 2D image stack. This task is not trivial due to the distortions such as tissue tearing, folding and missing at each slide. Performing registration for the whole tissue slices may be adversely affected by distorted tissue regions. Consequently, regional registration is found to be more effective. In this paper, we propose a new approach to an accurate and robust registration of regions of interest for whole slide images. We introduce the idea of multi-scale attention for registration. Results: Using mean similarity index as the metric, the proposed algorithm (mean +- std: 0.84 +- 0.11) followed by a fine registration algorithm (0.86 +- 0.08) outperformed the state-of-the-art linear whole tissue registration algorithm (0.74 +- 0.19) and the regional version of this algorithm (0.81 +- 0.15). The proposed algorithm also outperforms the state-of-the-art nonlinear registration algorithm (original: 0.82 +- 0.12, regional: 0.77 +- 0.22) for whole slide images and a recently proposed patch-based registration algorithm (patch size 256: 0.79 +- 0.16 , patch size 512: 0.77 +- 0.16) for medical images. Conclusion: Using multi-scale attention mechanism leads to a more robust and accurate solution to the problem of regional registration of whole slide images corrupted in some parts by major histological artifacts in the imaged tissue.

Abstract
Background: Residential aged care facility residents experience high rates of hospital admissions which are stressful, costly and often preventable. The EDDIE program is a hospital avoidance initiative designed to enable nursing and care staff to detect, refer and quickly respond to early signals of a deteriorating resident. The program was implemented in a 96-bed residential aged care facility in regional Australia.Methods: A prospective pre-post cohort study design was used to collect data on costs of program delivery, hospital admission rates and length of stay for the 12 months prior to, and following, the intervention. A Markov decision model was developed to synthesize study data with published literature in order to estimate the cost-effectiveness of the program. Quality adjusted life years (QALYs) were adopted as the measure of effectiveness.Results: The EDDIE program was associated with a 19% reduction in annual hospital admissions and a 31% reduction in the average length of stay. The cost-effectiveness analysis found the program to be both more effective and less costly than usual care, with 0.06 QALYs gained and $249,000 health system costs saved in a modelled cohort of 96 residents. A probabilistic sensitivity analysis estimated that there was an 86% probability that the program was cost-effective after taking the uncertainty of the model inputs into account. Conclusions: This study provides promising evidence for the effectiveness and cost-effectiveness of a nurse led, early intervention program in preventing unnecessary hospital admissions within a residential aged care facility. Further research in multi-site randomised studies is needed to confirm the generalisability of these results.

Abstract
Background: Globally, osteoarthritis (OA) is the third condition associated with disability. There is still poor treatment in OA but science holds the key to finding better treatments and a cure. It is essential to learn what’s important to patients from them to implement the most effective OA management. The OA Patients Task Force, conducted the Global OA Patient Perception Survey (GOAPPS)-the first global survey made by patients to analize the quality of life (QoL) & patient perceptions of care across countries. The goal was to collect data on OA patients' perception of OA to understand patients’ needs and expectations to improve OA management.Methods: Observational, cross-sectional study by online survey data collection from six countries, translated into three languages. The survey was comprised of 3 sections: patient demographics and clinical symptomology characteristics; relationship with physicians: perception of attention, treatment, and information provided; and OA impact on daily activity and QoL. The results of the survey were evaluated using the Limited Data Set. The survey results were analyzed using descriptive statistics to characterize the patients' answers. Additionally, Cronbach's alpha was calculated to determine internal consistency validity.Results. A total of 1512 surveys were completed in 6 countries. 84.2% of respondents reported pain/tenderness and 91.1% experienced limitations to physical activities. 42.3% of patients were not satisfied with their current OA treatment. 86% had comorbidities, especially hypertension, and obesity. 51.3% and 78% would like access to additional drug or additional non-drug/non-surgical treatments respectively. 48.2% of patients perceived their QoL to be affected by OA. The Cronbach's alpha was 0.61.Conclusions: OA has a significant impact on patients’ daily activities and their desire to play an active role in managing this disease. Patients are seeking additional treatments, especially no pharmacological/no surgical treatments stressing the need for investing in clinical research, implementing OA preventive measures, and managing interventions to improve the healthcare value chain in OA.
Nurses’ Knowledge, Attitude, and Fall Prevention Practices at South Korean Hospitals: A Cross-Sectional Survey
Authors: Cho Mi-young , Jang Sun Joo 
Published: October 2020

Abstract
Background: Fall-prevention activities are nursing interventions which are designed to improve patient safety. The introduction of evaluations of medical institutions and an increase in medical litigation has led institutions to emphasize the importance of fall-prevention activities. The current situation regarding falls among patients in small and medium-sized hospitals is poorly understood. This study assessed knowledge and attitudes regarding falls, and fall-prevention activities of nurses working in small- and medium-sized hospitals. Methods: Participants were 162 nurses from seven small- and medium-sized hospitals. Data on participants’ characteristics, education regarding patient falls, knowledge of stretcher cart use, attitudes regarding patient falls, and fall-prevention activities were collected from August 1 to September 1, 2016. Results: Nurses’ knowledge of patient falls was positively correlated with their experience with inpatient falls. Furthermore, nurses’ attitudes regarding falls were influenced by their nursing experience and fall prevention education. Attitudes positively correlated with fall-prevention activities, but knowledge did not. Nurses’ attitudes regarding patient falls were correlated with fall-prevention activities. Conclusion: Hospitals should develop incentive programs to improve nurses’ attitudes which are based on their subjective norms and tailored to each hospital’s specific circumstances to ensure engagement in fall prevention activities. In short, we recommend that consistent, repeated, and custom fall-prevention education should be implemented in small- and medium-sized hospitals to promote engagement in fall-prevention activities. Patient safety activities in small- and medium-sized hospitals can be enhanced by creating an environment that encourages active and self-directed participation in developing fall-prevention strategies using motivation and rewards.

Abstract
Background: Transanal dissection of the rectum has been recently introduced for ileal pouch-anal anastomosis (IPAA) in UC showing promising results. Thanks to the precise identification of the rectotomy site the risk of long rectal stump is avoided, and a single stapled anastomosis is performed easily.The aim of this study is to analyze our initial experience of transanal IPAA (Ta-IPAA), considering postoperative complications and medium-term functional outcomes.Methods: Our Center has experienced the transanal approach for proctectomy and IPAA since October 2018. All patients underwent Enhanced Recovery After Surgery (ERAS) protocol. Postoperative complications occurring within 30 days after surgery were taken into consideration. Fecal continence, genito-urinary activity and global quality of life at 1 and 6 months after ileostomy reversal have been assessed.Results: Until March 2019, 8 patients underwent Ta-IPAA. In all cases the laparoscopic approach was performed during the transabdominal phase; abdominal drainage was never used. At the time of the pouch construction a defunctioning loop ileostomy was created in all patients. Stoma closure was performed in all cases at a median time of 6 months after surgery. Postoperative complications occurred in only one patient, who showed rectal bleeding. There were no cases of anastomotic leakage.Medium-term functional outcomes were determined prospectively by a validated questionnaire (Cleveland Global Quality of Life). Fecal incontinence for liquid or solid stool, genitourinary and sexual functions were also investigated, showing comparable results with the literature data.Conclusions: In our experience, Ta-IPAA provided good short and medium-term functional results in UC.

Abstract
Background: Ectopic pregnancy is a major life- and fertility-threatening women’s health concern. As a result of advances in examination technology, an increasing number of ectopic pregnancies can be diagnosed early and treated with medical methods instead of surgery. The aim of this study was to summarize the clinical features and identify the predictors of success of methotrexate (MTX) treatment of ectopic pregnancy. Methods: This was a retrospective study of 238 ectopic pregnancies treated with MTX in the Department of Gynecology of Shaanxi Provincial People's Hospital from January 2017 to December 2017. Results: Patients were divided into two groups: the successful treatment group (n=166) and the failed treatment group (n=72). The overall success rate of MTX therapy for ectopic pregnancy was 69.75%. The mean initial beta-human chorionic gonadotropin (β-hCG) level was significantly lower in the successful treatment group than in the failed treatment group (2538.08 IU/L versus 3533.17 IU/L, P=0.000). The treatment success rate of the group with an initial β-hCG concentration less than 4000 IU/L was significantly higher than that of the group with an initial β-hCG concentration greater than 4000 IU/L. However, the success rate of the group with an initial β-hCG concentration greater than 4000 IU/L was still relatively high (54.55%). β-hCG levels were significantly increased on the 4th day in the failed treatment group (P=0.000). Compared to the initial β-hCG level, the day-4 β-hCG level increased by more than 8.21%, indicating that the treatment was effective. The diagnostic sensitivity was 88.6%, the specificity was 74.5%, and the area under the receiver operating characteristic (ROC) curve was 0.863 (95% confidence interval (CI): 0.805-0.920). Conclusions: MTX therapy as a treatment option is safe and effective for asymptomatic, hemodynamically stable patients with ectopic pregnancies who are interested in conservative treatment, regardless of the serum β-hCG level or adnexal mass size. The change in the β-hCG level between the initial day and the 4th day is an effective and early predictive tool for the success of MTX therapy for ectopic pregnancy.

Published: October 2020

Abstract
Background Anxiety among women in the perinatal period is common. Assessing the severity of perinatal anxiety will help monitor the progress of the patient through the stages of anxiety and facilitated the treatment. This study assesses the validity and reliability of the “Perinatal Anxiety Screening Scale” (PASS) in the Arabic language. Methods The PASS was translated into Arabic. 217 women in the antenatal and postnatal phase participated (92 antenatal and 125 postnatal) answered to PASS, GHQ12, EPDS-10, and DASS-21. Content validity, factor analysis, internal consistency, and test retest reliability were assessed. Results Content Validity Index (CVI) and Content Validity Ratio (CVR) were .88 and 0.79; respectively. The scale loaded on four components: acute anxiety, social anxiety, and dissociation; specific fears and trauma; general anxiety and adjustment; and perfectionism and control. Cronbach’s Alpha value for the scale was 0.78 and test retest correlation coefficient was 0.94. PASS significantly correlated with EPDS-10 (rho=0.46), GHQ-12(rho=0.58), the three components of DASS-21 (0.47, 0.50, and 0.43; respectively), and experiencing adverse life events. Conclusion The Arabic translated version of the PASS showed reasonably adequate validity and reliability and can be used to screen for anxiety disorder among women in the perinatal phase.

Abstract
Background: The incidence of intramedullary infection is increasing with increased use of intramedullary fixation for long bone fractures. However, appropriate treatment for infection after intramedullary nailing is unclear. The purpose of this study was to report the results of our treatment protocol for infection after intramedullary nailing: intramedullary nail removal, local debridement, reaming and irrigation, and antibiotic-loaded calcium sulfate implantation with or without segmental bone resection and distraction osteogenesis.Methods: We retrospectively reviewed the records of patients with an infection after intramedullary nailing treated from 2014 to 2017 at our center. Patients with follow-up of less than 24 months, received other treatment methods, or those with serious medical conditions were excluded from the analysis. Patients met the criteria were treated as described above, followed by distraction osteogenesis in 9 cases to repair bone defect. The infection remission rate, infection recurrence rate, and post-operative complication rates were assessed. Results: A total of 19 patients were included in the analysis. All of patients had satisfactory outcomes with an average follow-up of 38.1± 9.4 months (range, 24 to 55months). Eighteen patients (94.7%) achieved infection remission; 1 patient (5.3%) developed a reinfection that resolved after repeat debridement. Nine patients with bone defects (average size 4.7 ± 1.3 cm; range, 3.3 to 7.6 cm) were treated with bone transport which successfully restored the length of involved limb. The mean bone transport duration was 10.7 ± 4.0 months (range, 6.7 to 19.5 months). The majority of patients achieved full weight bearing and became pain free during the follow-up period. Postoperative complications mainly included prolonged aseptic drainage (7/19; 36.8%), re-fracture (1/19; 5.3%) and joint stiffness, which were successfully managed by regular dressing changes and re-fixation, respectively.Conclusion: Intramedullary nail removal, canal reaming and irrigation, and antibiotic-loaded calcium sulfate implantation (with or without distraction osteogenesis) is effective for treating infections after intramedullary nailing.
