Authors: Dong Susan , Khan Maria , Hashimi Farahnosh , Chamy Caroline , D’Souza Rohan 
Published: June 2020

Abstract
Background
As the number of indications for labour induction continue to increase, the focus has shifted to performing these procedures in an outpatient setting. This study aims to systematically review published data from randomized controlled trials that compare outpatient with inpatient labour induction, to ascertain the role of outpatient labour induction for low-risk pregnancies.

Methods
We conducted a systematic review wherein we searched MEDLINE, EMBASE, Biosis Previews®, and International Pharmaceutical Abstracts from inception to January 2020 to identify randomized controlled trials that reported on maternal, fetal and resource-related outcomes following outpatient versus inpatient labour induction. Pooled incidences and mean differences were calculated using random-effects meta-analysis. Risk-of-bias was assessed using the Cochrane Risk of Bias tool. Subgroup analysis was conducted based on the method of induction.

Results
Of the 588 records identified, 12 publications, representing nine independent randomized controlled trials conducted in Australia, Europe and North America, were included. These reported on 2615 cases of labour induction (1320 outpatients versus 1295 inpatients). Overall, apart from a higher number of suspicious fetal heart rate tracings [RR = 1.43 (1.10, 1.86)] and a shorter mean length of hospital stay [MD = 282.48 min (160.23, 404.73) shorter] in the outpatient group, there were no differences in delivery method, adverse outcomes or resource-use between the two arms. On subgroup analysis, when comparing the use of balloon catheters in both arms, those induced as outpatients had fewer caesarean deliveries [RR = 0.52 (0.30, 0.90)], a shorter admission-to-delivery interval [MD = 370.86 min (19.19, 722.54) shorter], and a shorter induction to delivery interval [MD = 330.42 min (120.13, 540.71) shorter].

Conclusion
Outpatient labour induction in resource-rich settings is at least as effective and safe, in carefully selected patient populations, when compared with inpatient labour induction. Whether outpatient labour induction results in lower rates of caesarean deliveries needs to be explored further.

Authors: Feng Mengmeng , Zhang Mengchao , Liu Yuanqing , Jiang Nan , Meng Qian , Wang Jia , Yao Ziyun , Gan Wenjuan , Dai Hui 
Published: June 2020

Abstract
Background
To explore the clinical value of texture analysis of MR images (multiphase Gd-EOB-DTPA-enhanced MRI and T2 weighted imaging (T2WI) to identify the differentiated degree of hepatocellular carcinoma (HCC).

Method
One hundred four participants were enrolled in this retrospective study. Each participant performed preoperative Gd-EOB-DTPA-enhanced MR scanning. Texture features were analyzed by MaZda, and B11 program was used for data analysis and classification. The diagnosis efficiencies of texture features and conventional imaging features in identifying the differentiated degree of HCC were assessed by receiver operating characteristic analysis. The relationship between texture features and differentiated degree of HCC was evaluated by Spearman’s correlation coefficient.

Results
The grey-level co-occurrence matrix -based texture features were most frequently extracted and the nonlinear discriminant analysis was excellent with the misclassification rate ranging from 3.33 to 14.93%. The area under the curve (AUC) of the combined texture features between poorly- and well-differentiated HCC, poorly- and moderately-differentiated HCC, moderately- and well-differentiated HCC was 0.812, 0.879 and 0.808 respectively, while the AUC of tumor size was 0.649, 0.660 and 0.517 respectively. The tumor size was significantly different between poorly- and moderately-HCC (p = 0.014). The COMBINE AUC values were not increased with tumor size combined.

Conclusions
Texture analysis of Gd-EOB-DTPA-enhanced MRI and T2WI was valuable and might be a promising method in identifying the differentiated degree of HCC. The poorly-differentiated HCC was more heterogeneous than well- and moderately-differentiated HCC.

Published: June 2020

Abstract
Background
Chemotherapy induced cardio-toxicity has been recognized as a serious side effect since the first introduction to anthracyclines (ANT). Cardio-toxicity among patients with breast cancer is well studied but the impact on patients with sarcoma is limited, even though they are exposed to higher ANT doses. The commonly used term for cardio-toxicity is cancer therapeutics related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction (LVEF) reduction of > 10%, to a value below 53%. The aim of our study was to estimate the prevalence of CTRCD in patients diagnosed with sarcoma and to describe the baseline risk factors and echocardiography parameters among that population.

Methods
Data were collected as part of the Israel Cardio-Oncology Registry (ICOR), enrolling all patients evaluated in the cardio-oncology clinic at our institution. The registry was approved by the local ethics committee and is registered in clinicaltrials.gov (Identifier: NCT02818517). All sarcoma patients were enrolled and divided into two groups - CTRCD group vs. non-CTRCD group.

Results
Among 43 consecutive patients, 6 (14%) developed CTRCD. Baseline cardiac risk factors were more frequent among the non-CTRCD group. Elevated left ventricular end systolic diameter and reduced Global Longitudinal Strain were observed among the CTRCD group. During follow-up, 2 (33%) patients died in the CTRCD group vs. 3 (8.1%) patients in the non-CTRCD group.

Conclusions
CTRCD is an important concern among patients with sarcoma, regardless of baseline risk factors. Echocardiography parameters may provide an early diagnosis of cardio-toxicity.
Levels of cytokines in the aqueous humor guided treatment of refractory macular edema in adult-onset coats’ disease
Authors: Wang Yewei , Fan Hua , Gao Ke , He Wei , Tao Yong 
Published: June 2020

Abstract
Background
Two cases with refractory macular edema secondary to adult-onset Coats’ disease underwent unsatisfactory treatment by intravitreal injections of anti-vascular endothelial growth factor (VEGF) drugs and retinal photocoagulation.

Case presentation
The authors highlight the guiding effect of the measurement of cytokines in the aqueous humor for the treatment of adult-onset Coats’ disease with refractory macular edema. In the two cases, typical Coats’ disease changes, including telangiectasis, subretinal exudation and macular edema were observed. Initial treatment consisted of intravitreal anti-VEGF drugs and retinal laser photocoagulation; however, the response was poor. Then, the aqueous humor was acquired and the cytokine concentrations were measured (Flow Cytometry Analysis, Beijing Giantmed Medical Diagnostics Lab). When the cytokine levels were tested every time there would be quality control, with a fixed concentration of cytokines samples to detect before the results reported. A low level of VEGF and a high level of inflammatory cytokines were found. Then, treatment was switched to intravitreal injection of dexamethasone implant (Ozurdex®) (Allergan, Inc., Irvine, Calif., USA), which resulted in resolution of the refractory macular edema and improvement of visual acuity in both cases.

Conclusions
For refractory macular edema secondary to adult-onset Coats’ disease, measurement of the levels of VEGF and inflammatory cytokines can help clinic doctors precisely investigate the molecular mechanism of macular edema and thereby find a suitable treatment.

Published: June 2020

Abstract
Background
To describe changes in the retina/choroid in patients with Serpiginous Choroiditis (SC) by Optical Coherence Tomography Angiography (OCTA) in a multimodal imaging approach.

Methods
Prospective, monocentric study of 24 eyes of 12 consenting patients diagnosed with SC, who underwent OCTA, which was analyzed and compared to other methods such as enhanced depth imaging-OCT, fluorescein angiography, indocyanine green angiography, and fundus autofluorescence.

Results
The study group consisted of 9 patients with peripapillary SC, 1 macular SC, and 2 atypical cases. All eyes presented an inactive SC confirmed by standard imaging. OCTA demonstrated the lesions tridimensionally in great detail. There was no difference in the angioarchitecture among the 3 forms of SC. A loss of the choriocapillaris/retinal pigment epithelium left a “window-defect”, where the vessels of larger caliber of the choroid became recognizable and their appearance inverted (“white-on-black”). A relationship between the presence of segmentation errors (SE) in the slabs and low visual acuity was established with a one-way ANOVA.

Conclusions
OCTA was able to non-invasively assess vascular lesions of the choroid/retina in patients with SC with a high degree of correlation to other diagnostic modalities. Consequent long-term assessments could lead to a better understanding of disease progression.

Published: June 2020

Abstract
Background
To examine the speed and accuracy of saccadic eye movements during a novel eye tracking threshold visual field assessment and determine whether eye movement parameters may improve ability to detect glaucoma.

Methods
A prospective study including both eyes of 31 patients with glaucoma and 23 controls. Standard automated perimetry (SAP) and eye tracking perimetry (saccadic vector optokinetic perimetry, SVOP) was performed. SVOP provided data on threshold sensitivity, saccade latency, and two measures of accuracy of saccades (direction bias and amplitude bias). The relationship between eye movement parameters and severity of glaucoma was examined and Receiver Operating Characteristic curves were used to assess ability to detect glaucoma.

Results
Patients with glaucoma had significantly slower saccades (602.9 ± 50.0 ms versus 578.3 ± 44.6 ms for controls, P = 0.009) and reduced saccade accuracy (direction bias = 7.4 ± 1.8 versus 6.5 ± 1.5 degrees, P = 0.006). There was a significant slowing of saccades and saccades became less accurate with worsening SAP sensitivity. Slower saccades were associated with increased odds of glaucoma; however, the AUC for saccade latency was only 0.635 compared to 0.914 for SVOP sensitivity.

Conclusion
Patients with glaucoma had significant differences in eye movements compared to healthy subjects, with a relationship between slower and less accurate eye movements and worse glaucoma severity. However, in a multivariable model, eye movement parameters were not of additional benefit in differentiating eyes with glaucoma from healthy controls.

AbstractBackgroundThe approach-avoidance training program (AATP) has shown preliminary promise as an add-on to standard treatment for alcohol dependence. However, knowledge is lacking as to whether the effectiveness of AATP can be enhanced further when performed in a typical drinking situation. The main aim of this study is to investigate whether approach-avoidance training implemented in a virtual reality bar environment is superior to the classical joystick PC-version of the AATP.MethodsThe study will be implemented as a randomized controlled trial. A total of 204consecutively enrolled alcohol use disorder (AUD) patients, recruited from alcohol inpatient clinics in Germany, Poland and Denmark, will be randomized into one of three groups at the start of standard alcohol treatment: group A) stimuli-relevant AATP + treatment as usual (TAU); group B) stimuli-relevant AATP in virtual reality + TAU, and group C) TAU only (control group). Treatment outcomes will be assessed at pre-treatment, post-treatment and 3-month follow-up. Repeated-measures ANOVA will be applied to compare the trajectories of the groups over time on drinking, craving and impulsiveness outcomes. It is hypothesized that the two experimental groups will achieve better treatment outcomes compared to group C and that group B will achieve better outcomes than group A.DiscussionThis study is the first trial examining the effectiveness of stimuli-relevant AATP delivered in a VR environment. The use of VR has shown promise in enhancing the effectiveness of other psychological treatments and since AATP has already been shown effective as add-on treatment, it is of interest to investigate whether these effects can be further enhanced by implementing the program in more ecologically valid environments. If proven effective, the AATP-VR can, like the AATP, be implemented easily and cheaply as add-on treatment or continued care to enhance the effectiveness of current evidence-based treatment.Trial registrationClinicalTrials.gov ID:NCT04283305Registration date: 24.02.20

Abstract
Background
There is increasing attention paid to the arrival of migrants from outwith the EU region to the European countries. Healthcare that is universally and equably accessible needs to be provided for these migrants throughout the range of national contexts and in response to complex and evolving individual needs. It is important to look at the evidence available on provision and access to healthcare for migrants to identify barriers to accessing healthcare and better plan necessary changes.

Methods
This review scoped 77 papers from nine European countries (Austria, Cyprus, France, Germany, Greece, Italy, Malta, Spain, and Sweden) in English and in country-specific languages in order to provide an overview of migrants’ access to healthcare. The review aims at identifying what is known about access to healthcare as well as healthcare use of migrants and refugees in the EU member states. The evidence included documents from 2011 onwards.

Results
The literature reviewed confirms that despite the aspiration to ensure equality of access to healthcare, there is evidence of persistent inequalities between migrants and non-migrants in access to healthcare services. The evidence shows unmet healthcare needs, especially when it comes to mental and dental health as well as the existence of legal barriers in accessing healthcare. Language and communication barriers, overuse of emergency services and underuse of primary healthcare services as well as discrimination are described.

Conclusions
The European situation concerning migrants’ and refugees’ health status and access to healthcare is heterogeneous and it is difficult to compare and draw any firm conclusions due to the scant evidence. Different diseases are prioritised by different countries, although these priorities do not always correspond to the expressed needs or priorities of the migrants. Mental healthcare, preventive care (immunization) and long-term care in the presence of a growing migrant older population are identified as priorities that deserve greater attention. There is a need to improve the existing data on migrants’ health status, needs and access to healthcare to be able to tailor care to the needs of migrants. To conduct research that highlights migrants’ own views on their health and barriers to access to healthcare is key.

Abstract
Background
Due to the SARS-CoV-2 pandemic, public health interventions have been introduced globally in order to prevent the spread of the virus and avoid the overload of health care systems, especially for the most severely affected patients. Scientific studies to date have focused primarily on describing the clinical course of patients, identifying treatment options and developing vaccines. In Germany, as in many other regions, current tests for SARS-CoV2 are not conducted on a representative basis and in a longitudinal design. Furthermore, knowledge about the immune status of the population is lacking. Nonetheless, these data are needed to understand the dynamics of the pandemic and hence to appropriately design and evaluate interventions. For this purpose, we recently started a prospective population-based cohort in Munich, Germany, with the aim to develop a better understanding of the state and dynamics of the pandemic.

Methods
In 100 out of 755 randomly selected constituencies, 3000 Munich households are identified via random route and offered enrollment into the study. All household members are asked to complete a baseline questionnaire and subjects ≥14 years of age are asked to provide a venous blood sample of ≤3 ml for the determination of SARS-CoV-2 IgG/IgA status. The residual plasma and the blood pellet are preserved for later genetic and molecular biological investigations. For twelve months, each household member is asked to keep a diary of daily symptoms, whereabouts and contacts via WebApp. If symptoms suggestive for COVID-19 are reported, family members, including children < 14 years, are offered a pharyngeal swab taken at the Division of Infectious Diseases and Tropical Medicine, LMU University Hospital Munich, for molecular testing for SARS-CoV-2. In case of severe symptoms, participants will be transferred to a Munich hospital. For one year, the study teams re-visits the households for blood sampling every six weeks.

Discussion
With the planned study we will establish a reliable epidemiological tool to improve the understanding of the spread of SARS-CoV-2 and to better assess the effectiveness of public health measures as well as their socio-economic effects. This will support policy makers in managing the epidemic based on scientific evidence.
Is retrospective assessment of health-related quality of life valid?
Authors: Lawson Andrew , Tan Aidan C. , Naylor Justine , Harris Ian A. 
Published: June 2020

Abstract
Background
Health-related quality of life (HRQoL) is a commonly used health outcome. For many acute conditions (e.g. fractures), retrospective measurement of HRQoL is necessary to establish pre-morbid health status. However, the validity of retrospective measurement of HRQoL following an intervening significant health event has not been established. The aim of this study was to test the validity of retrospective measurement (recall) of HRQoL by using a test-retest design to measure reliability and agreement between prospective and retrospective patient-reported HRQoL before and after an intervening health event (elective orthopaedic surgery).

Method
Participants were recruited from the pre-admission clinic of a metropolitan hospital. Participants were assessed for their HRQoL using the EQ-5D-5L at two time-points; prospectively at 2 weeks prior to their date of surgery and then retrospectively (recalling their pre-operative health) following elective hip or knee joint replacement surgery. Prospective measurements were compared with retrospective measurements for the five domain scores (nominal data) using intra-class correlation and for the EQ-Index score and EQ-Visual Analogue Scale (VAS) score (continuous data), using Pearson’s correlation. Agreement was tested in continuous variables using Lin’s coefficient of concordance (pc) and Bland-Altman plots.

Results
One hundred seventy-four patients consented to participate. Eighty-eight paired prospective and retrospective scores were collected and there was a median between-test period of 15 days. At a group level, the prospective measurements were similar to the retrospective measurements; the modes and means of the five domain scores were not different and the mean differences (MD) between the scores for EQ-Index (MD = 0.02, on a scale of 0–1) and EQ-VAS (MD = 0.53, on a scale of 1–100) were negligible. However, the correlation of paired scores was varied; the range of domain score correlations was 0.52 to 0.74, the concordance was substantial for the EQ-Index scores (pc = 0.76, 95% CI = 0.66, 0.84) and moderate for the EQ-VAS scores (pc = 0.46, 95% CI = 0.28, 0.61).

Conclusion
Agreement between prospective and retrospective measurements was high at a group level and moderate to substantial at an individual level. Retrospective measurement of HRQoL using the EQ-5D-5L in an orthopaedic clinical context is a valid alternative to using reference data to estimate baseline or pre-morbid health status.
