Abstract
Background
Malignant Ascites (MA) is a therapeutic dilemma significantly impairing patients’ quality of life (QoL). The Sequana Medical alfapump System (AP), a subcutaneous, externally rechargeable, implantable device, continually draining ascites via the urinary bladder, has been well established in liver cirrhosis, but not yet in MA. The AP-system was evaluated in cancer patients in reducing the need for large volume paracentesis (LVP).

Methods
A retrospective multicentre evaluation of all eligible patients who received an AP for MA-palliation was performed. AP was evaluated for its ability to reduce LVP and cross-correlated with adverse events (AE), survival and retrospective physician-reported QoL.

Results
Seventeen patients with median age of 63 years (range: 18–81), 70.6% female, across 7 primary tumour types were analysed. Median duration of AP-implantation was 60 min (range: 30–270) and median post-implantation hospital stay: 4 days (range: 2–24). Twelve protocol-defined AE occurred in 5 patients (29.4%): 4 kidney failures, 4 pump/catheter-related blockages, 3 infections/peritonitis and 1 wound dehiscence. Median ascitic volume (AV) pumped daily was 303.6 ml/day (range:5.6–989.3) and median total AV drained was 28 L (range: 1–638.6). Median patient post-AP-survival was 111 days (range:10–715) and median pump survival was 89 days (range: 0–715). Median number of paracenteses was 4 (range: 1–15) per patient pre-implant versus 1 (range: 0–1) post-implant (p = 0.005). 71% of patients were reported to have an improvement of at least one physician reported QoL-parameters.

Conclusions
AP appears to be effective in palliating patients with MA by an acceptable morbidity profile. Its broader implementation in oncology services should be further explored.

Ethno-pharmacological survey of herbal remedies used in the treatment of paediatric diseases in Buhunga parish, Rukungiri District, Uganda
Authors: Tugume Patience , Nyakoojo Clement 
Published: December 2019

Abstract
Background
Plants have been used as a primary source of medicine since ancient times and about 80% of the world’s population use herbal medicine to treat different ailments. Plant use knowledge differs in space and time and thus requires documentation to avoid its loss from one generation to another.

Methods
In order to accomplish the survey, semi-structured questionnaires were used. The data collected included names of plant species, parts used, ailments treated, growth habit, methods of preparation and mode of administration of the herbal remedies. Descriptive statistics were used to present the data in form of tables and a graph.

Results
Results showed that 50 plant species belonging to 26 families were utilized in the treatment of paediatric diseases of which Asteraceae and Lamiaceae were the most common. Leaves (80%) were the most commonly used and decoctions were the main method of preparation. Twenty nine health conditions were treated out of which digestive disorders, malaria and respiratory tract infections were predominant. Herbs and shrubs were equally dominant.

Conclusion
Herbal remedies are an important source of treatment for paediatric diseases in Buhunga Parish. However, there is need for collaboration between herbal medicine users and scientific institutions to help in the discovery of new drugs based on indigenous knowledge. Scientists ought to explore suitable methods of preparation and dosage formulations in order to achieve the best benefits from herbal remedies.
Effects of fish oil supplement on psoriasis: a meta-analysis of randomized controlled trials
Authors: Yang Shih-Jyun , Chi Ching-Chi 
Published: December 2019

Abstract
Background
Fish oils, which contain omega-3 polyunsaturated fatty acids as the active ingredients, possess anti-inflammatory activities and may have therapeutic potential in diseases with an inflammatory etiology. Fish oil supplement has been advocated for treating psoriasis which is a chronic inflammatory dermatosis.

Objective
We aimed to investigate the effects of fish oil supplement on psoriasis.

Methods
We searched CENTRAL, Embase and MEDLINE on 24 January 2018 for randomized control trials (RCTs) on the effects of fish oil supplement in treating psoriasis. The Cochrane Collaboration’s tool was used to assess the risk of bias of included RCTs. We performed a random-effects model meta-analysis to obtain the pooled treatment effect estimates.

Results
We included 13 RCTs with 625 participants. Three RCTs involving 337 participants provided usable data for meta-analysis. Fish oil supplement did not significantly reduce the severity of psoriasis when assessed by Psoriasis Area and Severity Index score (mean difference − 0.28; 95% confidence interval − 1.74 to 1.19).

Conclusion
The current evidence does not support the use of fish oil supplement in treating psoriasis.

Published: December 2019

AbstractBackgroundCase-based learning (CBL) is a highly interactive instructional format widely used in medical education. One goal of CBL is to integrate basic biomedical knowledge and its application to concrete patient cases and their clinical management. In this context, we focus the role of teacher questions as triggers for reproductive vs. elaborative student responses. Specifically, our research questions concern the kinds of questions posed by clinical teachers, the kinds of responses given by students, the prediction of student responses based upon teacher questions, and the differences between the two medical disciplines in focus of our study, internal medicine and surgery.MethodsWe analyse 19 videotaped seminars (nine internal medicine, ten surgery) taught by clinicians and attended by advanced medical students. Multiple raters performed a low-inference rating process using a theory-based categorical scheme with satisfactory interrater-reliability.ResultsWe found that medical teachers mostly posed initial (instead of follow-up) questions and that their questions were more often closed (instead of open). Also, more reasoning (than reproductive) questions were posed. A high rate of student non-response was observed while elaborative and reproductive student responses had a similar prevalence. In the prediction context, follow-up reasoning questions were associated with low non-response and many elaborative answers. In contrast, the highest student non-response rate followed open reproduction questions and initial reasoning questions. Most reproductive statements by students were made following closed reproduction questions.ConclusionsThese results deepen our understanding of interactive, questions-driven medical teaching and provide an empirical basis for clinical teachers to use questions in didactically fruitful ways.
Reporting of ethical approval and informed consent in clinical research published in leading nursing journals: a retrospective observational study
Authors: Wu Yanni , Howarth Michelle , Zhou Chunlan , Hu Mingyu , Cong Weilian 
Published: December 2019

Abstract
Background
Ethical considerations play a prominent role in the protection of human subjects in clinical research. To date the disclosure of ethical protection in clinical research published in the international nursing journals has not been explored. Our research objective was to investigate the reporting of ethical approval and informed consent in clinical research published in leading international nursing journals.

Methods
This is a retrospective observational study. All clinical research published in the five leading international nursing journals from the SCI Journal Citation Reports between 2015 and 2017 were retrieved to evaluate for evidence of ethical review.

Results
A total of 2041 citations have been identified from the contents of all the five leading nursing journals that were published between 2015 and 2017. Out of these, 1284 clinical studies have been included and text relating to ethical review has been extracted. From these, most of prospective clinical studies (87.5%) discussed informed consent. Only half of those (52.9%) reported that written informed consent had been obtained; few (3.6%) reported oral consent, and few (6.8%) used other methods such as online consent or completion and return of data collection (such as surveys) to denote assent. Notably, 36.2% of those did not describe the method used to obtain informed consent and merely described that “consent was obtained from participants or participants agreed to join in the research”. Furthermore, whilst most of clinical studies (93.7%) mentioned ethical approval; 92.5% of those stated the name of ethical committee and interestingly, only 37.1% of those mentioned the ethical approval reference. The rates of reporting ethical approval were different between different study type, country, and whether financial support was received (all P < 0.05).

Conclusion
The reporting of ethics in leading international nursing journals demonstrates progress, but improvement of the transparency and the standard of ethical reporting in nursing clinical research is required.
Improving reference prioritisation with PICO recognition
Authors: Brockmeier Austin J. , Ju Meizhi , Przybyła Piotr , Ananiadou Sophia 
Published: December 2019

AbstractBackgroundMachine learning can assist with multiple tasks during systematic reviews to facilitate the rapid retrieval of relevant references during screening and to identify and extract information relevant to the study characteristics, which include the PICO elements of patient/population, intervention, comparator, and outcomes. The latter requires techniques for identifying and categorising fragments of text, known as named entity recognition.MethodsA publicly available corpus of PICO annotations on biomedical abstracts is used to train a named entity recognition model, which is implemented as a recurrent neural network. This model is then applied to a separate collection of abstracts for references from systematic reviews within biomedical and health domains. The occurrences of words tagged in the context of specific PICO contexts are used as additional features for a relevancy classification model. Simulations of the machine learning-assisted screening are used to evaluate the work saved by the relevancy model with and without the PICO features. Chi-squared and statistical significance of positive predicted values are used to identify words that are more indicative of relevancy within PICO contexts.ResultsInclusion of PICO features improves the performance metric on 15 of the 20 collections, with substantial gains on certain systematic reviews. Examples of words whose PICO context are more precise can explain this increase.ConclusionsWords within PICO tagged segments in abstracts are predictive features for determining inclusion. Combining PICO annotation model into the relevancy classification pipeline is a promising approach. The annotations may be useful on their own to aid users in pinpointing necessary information for data extraction, or to facilitate semantic search.
Exploring the experiences of being an ethnic minority student within undergraduate nurse education: a qualitative study
Authors: Flateland Sylvi Monika , Pryce-Miller Maxine , Skisland Anne Valen-Sendstad , Tønsberg Anne Flaatten , Söderhamn Ulrika 
Published: December 2019

AbstractBackgroundStudents studying in a country where another language is spoken face multiple challenges including their ability to fully integrate with peers and academic pressures in trying to obtain an undergraduate nursing degree. The aim of the study was to explore the lived experiences of students, from varying cultural and ethnic backgrounds, undertaking an undergraduate nursing degree.MethodsThe study adopted a qualitative design and eight individual semi-structured interviews were conducted. The interviews were analysed using manifest content analysis according to Graneheim and Lundman.ResultsStudents reported feelings of isolation and the lack of opportunities to integrate with native students within academia and practice. The need for personal support was a crucial factor that was independent of gender and students reported challenges related to both language and culture during the programme.ConclusionsSuggestions arising from this study includes appropriate support systems within academia and practice. It is imperative that universities and practice settings promote and integrate cultural awareness within academia and practice in meeting the needs of students and providing culturally appropriate nursing care, thereby providing opportunities for all students to become competent and professional practitioners.

Published: December 2019

Abstract
Background
We aimed to identify the risk factors associated with early, late and long-term readmissions in women diagnosed with breast cancer participating in screening programs.

Methods
We performed a multicenter cohort study of 1055 women aged 50–69 years participating in Spanish screening programs, diagnosed with breast cancer between 2000 and 2009, and followed up to 2014. Readmission was defined as a hospital admission related to the disease and/or treatment complications, and was classified as early (< 30 days), late (30 days-1 year), or long-term readmission (> 1 year). We used logistic regression to estimate the adjusted odds ratios (aOR), and 95% confidence intervals (95% CI) to explore the factors associated with early, late and long-term readmissions, adjusting by women’s and tumor characteristics, detection mode, treatments received, and surgical and medical complications.

Results
Among the women included, early readmission occurred in 76 (7.2%), late readmission in 87 (8.2%), long-term readmission in 71 (6.7%), and no readmission in 821 (77.8%). Surgical complications were associated with an increased risk of early readmissions (aOR = 3.62; 95%CI: 1.27–10.29), and medical complications with late readmissions (aOR = 8.72; 95%CI: 2.83–26.86) and long-term readmissions (aOR = 4.79; 95%CI: 1.41–16.31).

Conclusion
Our results suggest that the presence of surgical or medical complications increases readmission risk, taking into account the detection mode and treatments received. Identifying early complications related to an increased risk of readmission could be useful to adapt the management of patients and reduce further readmissions.

Resurgence of malaria infection after mass treatment: a simulation study
Authors: Smith Thomas A. , Pemberton-Ross Peter , Penny Melissa A. , Chitnis Nakul 
Published: December 2019

Abstract
Background
Field studies are evaluating if mass drug administration (MDA) might shorten the time to elimination of Plasmodium falciparum malaria, when vector control measures and reactive surveillance strategies are scaled-up. A concern with this strategy is that there may be resurgence of transmission following MDA.

Methods
A conceptual model was developed to classify possible outcomes of an initial period of MDA, followed by continuously implementing other interventions. The classification considered whether elimination or a new endemic stable state is achieved, and whether changes are rapid, transient, or gradual. These categories were informed by stability analyses of simple models of vector control, case management, and test-and-treat interventions. Individual-based stochastic models of malaria transmission (OpenMalaria) were then used to estimate the probability and likely rates of resurgence in realistic settings. Effects of concurrent interventions, including routine case management and test-and-treat strategies were investigated.

Results
Analysis of the conceptual models suggest resurgence will occur after MDA unless transmission potential is very low, or the post-MDA prevalence falls below a threshold, which depends on both transmission potential and on the induction of bistability. Importation rates are important only when this threshold is very low. In most OpenMalaria simulations the approximately stable state achieved at the end of the simulations was independent of inclusion of MDA and the final state was unaffected by importation of infections at plausible rates. Elimination occurred only with high effective coverage of case management, low initial prevalence, and high intensity test-and-treat. High coverage of case management but not by test-and-treat induced bistability. Where resurgence occurred, its rate depended mainly on transmission potential (not treatment rates).

Conclusions
A short burst of high impact MDA is likely to be followed by resurgence. To avert resurgence, concomitant interventions need either to substantially reduce average transmission potential or to be differentially effective in averting or clearing infections at low prevalence. Case management at high effective coverage has this differential effect, and should suffice to avert resurgence caused by imported cases at plausible rates of importation. Once resurgence occurs, its rate depends mainly on transmission potential, not on treatment strategies.
Does migrant background predict to what extent colorectal cancer patients want to be informed about their life expectancy? – a cross-sectional analysis
Authors: Leonhardt Marja , Aschenbrenner Katja , Kreis Martin E. , Lauscher Johannes C. 
Published: December 2019

Abstract
Background
Although migrant health is a topic of interest across Europe and although health care services in Germany consider migrant health issues, people with a migrant background often experience difficulties regarding health care provision. The prevalence of various cancers among migrants is lower relative to non-migrants although this equalizes with increasing duration of residence. There are documented differences in health behavior and disease-coping strategies between migrants and non-migrants, but data are scarce on this subject. This analysis investigates the extent of information migrant and non-migrant colorectal cancer (CRC) patients in Germany want about their life expectancy and the level of trust they have in their treating physician.

Method
Data from 522 CRC patients were collected through a self-reported questionnaire. Migrant background was determined by the patients’ and/or their parents’ birthplace. Bivariate analyses were applied to determine the differences between migrants and non-migrants. A multivariate analysis was used to measure the effect of migration background, demographics, and cancer stage and treatment on the preferred extent of information about life expectancy and trust in their treating physician.

Results
There were no significant differences regarding demographics or cancer stage and treatment between migrant and non-migrant CRC patients. Having a migrant background had no influence on the level of trust in the treating physician, but migrants preferred to be less informed about their life expectancy than non-migrants (21.4% vs. 13.4%, p = 0.04). The multivariate analysis showed that men (aOR = 2.102, CI: 1.123–3.932) and patients with a non-migrant background (aOR = 5.03, CI: 1.02–24.73) preferred receiving information about the approximate value of their life expectancy, rather than receiving no information.

Conclusion
The study found more similarities than discrepancies between migrant and non-migrant CRC patients regarding demographic factors and stage of disease and treatment, which may be a consequence of an increasingly homogeneous cross-cultural society. However, cultural differences between the minority and host population remain and should always be taken into account in daily clinical practice and in the communication skills training of health care professionals. The study also indicates that recording migration background into health registers would facilitate migrant-sensitive research.

Abstract
Background
While Salmonella serotyping is of paramount importance for the disease intervention of salmonellosis, a fast and easy-to-operate molecular serotyping solution remains elusive. We have developed a multiplex ligation reaction based on probe melting curve analysis (MLMA) for the identification of 30 common Salmonella serovars.

Methods
Serovar-specific primers and probes were designed based on a comparison of gene targets (wzx and wzy encoding for somatic antigen biosynthesis; fliC and fljB for flagellar antigens) from 5868 Salmonella genomes. The ssaR gene, a type III secretion system component, was included for the confirmation of Salmonella.

Results
All gene targets were detected and gave expected Tm values during assay evaluation. Cross reactions were not demonstrated between the 30 serovars (n = 211), or with an additional 120 serovars (n = 120) and other Enterobacteriaceae (n = 3). The limit of identification for all targets ranged from using 1.2 ng/μL to 1.56 ng/μL of DNA. The intra- and inter-assay standard deviations and the coefficients of variation were no more than 0.5 °C and less than 1% respectively, indicating high reproducibility. From consecutive outpatient stool samples (n = 3590) collected over a 10-month period at 11 sentinel hospitals in Shenzhen, China, we conducted a multicenter study using the traditional Salmonella identification workflow and the MLMA assay workflow in parallel. From Salmonella isolates (n = 496, 13.8%) derived by both workflows, total agreement (kappa = 1.0) between the MLMA assay and conventional serotyping was demonstrated.

Conclusions
With an assay time of 2.5 h, this simple assay has shown promising potential to provide rapid and high-throughput identification of Salmonella serovars for clinical and public health laboratories to facilitate timely surveillance of salmonellosis.
