AbstractBackgroundEnd-stage kidney disease (ESKD) and the required kidney replacement therapy (KRT) are significant public health challenges for low-and-middle-income countries. The South African government adopted a KRT rationing policy to balance the growing need for KRT and scarce resources. We aimed to describe the epidemiology and KRT access in patients with ESKD referred to the main public sector hospital in the Free State Province, South Africa.MethodsA retrospective study of adult patients with ESKD admitted to Universitas Academic Hospital for KRT, was conducted between 1 January 2016 and 31 December 2018. A review of the KRT committee decisions to offer or deny KRT based on the KRT rationing policy of the Free State was undertaken. Demographic information, KRT committee outcomes, laboratory test results, and clinical details were collected from assessment tools, KRT committee meeting diaries, and electronic hospital records.ResultsOf 363 patients with ESKD referred for KRT access, 96 with incomplete records were excluded and 267 were included in the analysis. Median patient age was 40 (interquartile range, 33‒49) years, and male patients accounted for 56.2 % (150/267,p = 0.004) of the cohort. The average annual ESKD incidence was 49.9 (95 % confidence interval [CI], 35.8‒64.0) per-million-population. The most prevalent comorbidities were hypertension (42.3 %; 113/267), human immunodeficiency virus (HIV) (28.5 %; 76/267), and diabetes mellitus (19.1 %; 51/267). The KRT access rate was 30.7 % (82/267), with annual KRT incidence rates of 8.05 (95 % CI, 4.98‒11.1), 11.5 (95 % CI, 7.83‒15.1), and 14.1 (95 % CI, 10.3‒18.0) per-million-population in 2016, 2017, and 2018, respectively. Advanced organ dysfunction was the commonest reason recorded for KRT access denial (58.9 %; 109/185). Age (odds ratio [OR], 1.04; 95 % CI, 1.00‒1.07;p = 0.024) and diabetes (OR, 5.04; CI, 1.69‒15.03;p = 0.004) were independent predictors for exclusion from KRT, while hypertension (OR, 1.80; 1.06‒3.04;p = 0.029) independently predicted advanced organ dysfunction resulting in KRT exclusion.ConclusionsNon-communicable and communicable diseases, including hypertension, diabetes, and HIV, contributed to ESKD, highlighting the need for improved early prevention strategies to address a growing incidence rate. Two-thirds of ESKD patients were unable to access KRT, with age, diabetes mellitus, and advanced organ dysfunction being significant factors adversely affecting KRT access.

Abstract
Background
In patients with multiple sclerosis (MS), the disease’s complications and manifestations affect a person’s ability to function normally and leads to further disruptions in their education, family life, job opportunities, and daily life activities, thereby reduce their quality of life. Different factors as facilitators or inhibitors affect the quality of life in patients with MS. This study aimed to explain the facilitators of quality of life in patients with MS.

Methods
This research applied qualitative methodology, utilizing semi-structured interviews with individuals with MS and their family members/caregivers. Purposeful sampling was done among people who referred to Isfahan MS Association. Participants were selected with a maximum variation in terms of gender, age, education, occupation and marital status. Interviews were continued to reach data saturation. The gathered data were concurrently analyzed by the content analysis technique. MAXQDA software version 10 was used for data management.

Results
Saturation was reached after eighteen interviews. A total of three main categories and 8 sub-categories were extracted from the data. The identified facilitators were: personal facilitators (leisure time and coping strategies), interpersonal facilitators (exercise therapy, social support and social organizations) and needs and suggestions for improvement (family therapy, adopting urban architecture and facilities, and supportive systems).

Conclusions
Based on these findings, in order to improve the quality of life in patients with MS, we should pay attention to factors such as leisure time, spirituality and positive thinking, exercise, social support and social organizations. Health professionals, the government, community and families could help to improve patients’ quality of life through adapting urban architecture, holding family therapy sessions and providing supportive systems.

Abstract
Background
There are numerous barriers to identifying patients with silent brain infarcts (SBIs) and white matter disease (WMD) in routine clinical care. A natural language processing (NLP) algorithm may identify patients from neuroimaging reports, but it is unclear if these reports contain reliable information on these findings.

Methods
Four radiology residents reviewed 1000 neuroimaging reports (RI) of patients age > 50 years without clinical histories of stroke, TIA, or dementia for the presence, acuity, and location of SBIs, and the presence and severity of WMD. Four neuroradiologists directly reviewed a subsample of 182 images (DR). An NLP algorithm was developed to identify findings in reports. We assessed interrater reliability for DR and RI, and agreement between these two and with NLP.

Results
For DR, interrater reliability was moderate for the presence of SBIs (k = 0.58, 95 % CI 0.46–0.69) and WMD (k = 0.49, 95 % CI 0.35–0.63), and moderate to substantial for characteristics of SBI and WMD. Agreement between DR and RI was substantial for the presence of SBIs and WMD, and fair to substantial for characteristics of SBIs and WMD. Agreement between NLP and DR was substantial for the presence of SBIs (k = 0.64, 95 % CI 0.53–0.76) and moderate (k = 0.52, 95 % CI 0.39–0.65) for the presence of WMD.

Conclusions
Neuroimaging reports in routine care capture the presence of SBIs and WMD. An NLP can identify these findings (comparable to direct imaging review) and can likely be used for cohort identification.
How do pregnant women’s perceptions of obstetric forceps change according to their demographic background: a cross sectional study
Authors: Hitt Jasmine M. , Martin Angela S. , Dietrich Jordan E. , Ahmed Natasha , Lee Gene T. 
Published: May 2021

Abstract
Background
Women’s attitudes towards obstetric forceps likely contribute to declining use and opportunities for residency training, but formal documentation of women’s attitudes towards obstetric forceps is currently limited. A clearer understanding should help guide our attempts to preserve its use in modern obstetrics and to improve residency training. Our objective is to document women’s attitudes towards obstetric forceps and the influence basic demographic variables have on those attitudes.

Methods
A cross sectional study was performed. We developed a one-time anonymous structured 5-question survey that was given to all women with low-risk pregnancies presenting to our medical center for prenatal care between October 2018–December 2018. The questionnaire asked for the woman’s self-reported age, race, education level and insurance type. The five questions were as follows: (1) Do you think forceps should be used to deliver babies, (2) Is forceps safe for the baby, (3) Is forceps safe for the mother, (4) Do you think forceps can help to lower the cesarean section rate, (5) Do you think physicians in training should learn to place forceps on a real patient. We calculated means and proportions for the responses according to the overall group and various subgroups. Statistical analysis included Kruskall-Wallis or Mann-Whitney tests as appropriate. Results were also adjusted by regression using a Generalized Linear Model. Power calculation showed sample size of 384 was required.

Results
A total of 499 women returned the questionnaire. Response rate was 56.8% (499/878). The findings suggest that women’s perceptions towards forceps are generally negative. Women with white ethnicity, college education or higher and private insurance did have more favorable views than their counterparts, but the majority still had unfavorable views. Age was not shown to have a significant effect on maternal attitude.

Conclusion
Women’s views towards forceps use in the University of Kansas Medical Center are negative and may be contributing to the decline of its use. Improving women’s perceptions of forceps would require multiple different strategies rather than a single focused easily-implemented message. If forceps training continues, such training will rely on a minority of women who will accept forceps use in childbirth.

Abstract
Background
While clinical trial evidence has firmly established the efficacy of several atypical antipsychotics (AAPs) for treating bipolar depression, no randomized controlled trials (RCT’s) comparing AAPs have been conducted. This Bayesian network meta-analysis (NMA) compared the relative efficacy and tolerability of AAP monotherapy in adults with bipolar depression.

Methods
Efficacy measures included change in Montgomery Åsberg Depression Rating Scale (MADRS), Clinical Global Improvement – Bipolar Disorder (CGI-BP), response, and remission. Multiple tolerability outcomes were examined. Results from random effects models were reported as difference in change from baseline for continuous variables or odds ratios for dichotomous variables. Treatments were ranked using the surface under the curve cumulative ranking probabilities. Number needed to treat (NNT) and harm (NNH) were calculated.

Results
Eighteen RCT’s met inclusion criteria of the systematic literature review. On change in MADRS, lurasidone (− 4.71 [95% Crl − 6.98, − 2.41]), quetiapine (− 4.80 [− 5.93, − 3.72]), olanzapine (− 4.57 [− 5.92, − 3.20]), and cariprazine (− 2.29 [− 3.47, − 1.09]) were more efficacious than placebo. Lurasidone was associated with a significantly greater odds of response (≥50% improvement in MADRS) compared to cariprazine (1.78 [95% Crl 1.08, 2.77]), aripiprazole (2.38 [1.38, 3.85]), and ziprasidone (2.47 [1.41, 3.98]), but was similar to olanzapine (1.68 [0.99,2.65]) and quetiapine (1.25 [0.78, 1.90]). For change in CGI-BP-S-overall score, lurasidone was significantly better than cariprazine (− 0.38 [95% Crl − 0.66,-0.10]) and ziprasidone (− 0.58 [− 0.91,-0.26]), but similar to quetiapine (− 0.08 [− 0.36, 0.19])and olanzapine (− 0.04 [− 1.41, 1.46]). Lurasidone (0.34 kg [95% Crl − 0.22, 0.89]) and aripiprazole (0.20 kg [− 0.59, 1.00]) had a similar weight change compared to placebo, but olanzapine (2.88 kg [2.40, 3.36]), quetiapine (1.17 kg [0.84, 1.49]), and cariprazine (0.65 kg [0.34, 0.96]) were associated with greater weight gain. The NNT for response was the lowest for lurasidone (NNT = 5) followed by quetiapine (NNT = 6), olanzapine (NNT = 10) and cariprazine (NNT = 12).

Conclusions
In this NMA in adults with bipolar depression, which evaluated change in depressive symptoms (assessed by MADRS) across short-term trials, the largest improvement versus placebo was observed for lurasidone, olanzapine and quetiapine with cariprazine, showing a smaller treatment effect. Aripiprazole and ziprasidone were ineffective for the treatment of bipolar depression. Improvement in CGI-BP-S score for lurasidone was larger than cariprazine and ziprasidone but similar to quetiapine and olanzapine. Based on short term studies lurasidone and aripiprazole had similar weight gain compared to placebo.
OnTARi: an ontology for factors influencing therapy adherence to rehabilitation
Authors: Steiner Bianca , Saalfeld Birgit , Elgert Lena , Haux Reinhold , Wolf Klaus-Hendrik 
Published: May 2021

Abstract
Background
Adherence and motivation are key factors for successful treatment of patients with chronic diseases, especially in long-term care processes like rehabilitation. However, only a few patients achieve good treatment adherence. The causes are manifold. Adherence-influencing factors vary depending on indications, therapies, and individuals. Positive and negative effects are rarely confirmed or even contradictory. An ontology seems to be convenient to represent existing knowledge in this domain and to make it available for information retrieval.

Methods
First, a manual data extraction of current knowledge in the domain of treatment adherence in rehabilitation was conducted. Data was retrieved from various sources, including basic literature, scientific publications, and health behavior models. Second, all adherence and motivation factors identified were formalized according to the ontology development methodology METHONTOLOGY. This comprises the specification, conceptualization, formalization, and implementation of the ontology “Ontology for factors influencing therapy adherence to rehabilitation” (OnTARi) in Protégé. A taxonomy-oriented evaluation was conducted by two domain experts.

Results
OnTARi includes 281 classes implemented in ontology web language, ten object properties, 22 data properties, 1440 logical axioms, 244 individuals, and 1023 annotations. Six higher-level classes are differentiated: (1) Adherence, (2) AdherenceFactors, (3) AdherenceFactorCategory, (4) Rehabilitation, (5) RehabilitationForm, and (6) RehabilitationType. By means of the class AdherenceFactors 227 adherence factors, thereof 49 hard factors, are represented. Each factor involves a proper description, synonyms, possibly existing acronyms, and a German translation. OnTARi illustrates links between adherence factors through 160 influences-relations. Description logic queries implemented in Protégé allow multiple targeted requests, e.g., for the extraction of adherence factors in a specific rehabilitation area.

Conclusions
With OnTARi, a generic reference model was built to represent potential adherence and motivation factors and their interrelations in rehabilitation of patients with chronic diseases. In terms of information retrieval, this formalization can serve as a basis for implementation and adaptation of conventional rehabilitative measures, taking into account (patient-specific) adherence factors. OnTARi also enables the development of medical assistance systems to increase motivation and adherence in rehabilitation processes.
Epidemiological analysis of classical swine fever in wild boars in Japan
Authors: Shimizu Yumiko , Hayama Yoko , Murato Yoshinori , Sawai Kotaro , Yamaguchi Emi , Yamamoto Takehisa 
Published: May 2021

Abstract
Background
Classical swine fever (CSF) is a contagious disease of pigs and wild boars that is transmitted through direct/indirect contact between animals or CSF virus-contaminated fomites. When the disease re-emerged in 2018 in Japan, a CSF-infected wild boar was reported shortly after the initial pig farm outbreak; subsequently, the disease spread widely. To control the disease spread among wild boars, intensive capturing, fencing, and oral bait vaccination were implemented with concomitant virological and serological surveillance. This study aimed to describe the disease spread in the wild boar population in Japan from September 2018, when the first case was reported, to March 2020, based on the surveillance data. We conducted statistical analyses using a generalized linear mixed model to identify factors associated with CSF infection among wild boars. Moreover, we descriptively assessed the effect of oral bait vaccination, which started in March 2019 in some municipalities in the affected areas.

Results
We observed a faster CSF infection spread in the wild boar population in Japan compared with the CSF epidemics in European countries. The infection probability was significantly higher in dead and adult animals. The influence of the multiple rounds of oral bait vaccination was not elucidated by the statistical modeling analyses. There was a decrease and increase in the proportion of infected and immune animals, respectively; however, the immunization in piglets remained insufficient after vaccination for 1 year.

Conclusions
Conditions regarding the wild boar habitat, including forest continuity, higher wild boar population density, and a larger proportion of susceptible piglets, were addressed to increase the infection risk in the wild boar population. These findings could improve the national control strategy against the CSF epidemic among wild boars.

Abstract
Background
In French Guiana, gold miners working illegally represents a major reservoir of malaria. This mobile population, mainly of Brazilian descent, enters the French Guianese forest from neighbouring countries, Suriname and Brazil. A complex and innovative intervention was piloted as a cooperation with the three involved countries involved to control malaria in this specific population. The principle was that health workers called “facilitators” provide the participants with a self-diagnosis and self-treatment kit along with adequate training and material to rapidly manage an episode of malaria symptoms on their own, when they find themselves isolated from health care services.

Methods
This paper describes the design, development, content of the intervention and players’ organization of this multi-country project, the opportunities and constraints encountered, and the lessons learnt at this stage.

Results
The choice not to implement the usual “Test and Treat” approach within the community is mainly driven by regulatory reasons. The content of medical messages tends to balance the tension between thoroughness, accuracy and efficacy. The wide range of tools developed through a participatory approach was intended to cope with the challenges of the literacy level of the target population. Despite the difficulties encountered due to language, regulation differences and distance between partners, cooperation was fruitful, due to the complementary of stakeholders, their involvement at all important stages and regular face-to-face meetings.

Discussion and conclusion
This experience shows the feasibility of an ambitious project of action-research in a border malaria context, involving several countries and with a mobile and undocumented population. It reveals some factors of success which may be transferable in analogous settings.

Abstract
Background
Despite the current therapeutic options for the treatment of inflammatory bowel disease, surgery is still frequently required in the emergency setting, although the number of cases performed seems to have decreased in recent years.
The World Society of Emergency Surgery decided to debate in a consensus conference of experts, the main pertinent issues around the management of inflammatory bowel disease in the emergent situation, with the need to provide focused guidelines for acute care and emergency surgeons.

Method
A group of experienced surgeons and gastroenterologists were nominated to develop the topics assigned and answer the questions addressed by the Steering Committee of the project. Each expert followed a precise analysis and grading of the studies selected for review. Statements and recommendations were discussed and voted at the Consensus Conference of the 6th World Society of Emergency Surgery held in Nijmegen (The Netherlands) in June 2019.

Conclusions
Complicated inflammatory bowel disease requires a multidisciplinary approach because of the complexity of this patient group and disease spectrum in the emergency setting, with the aim of obtaining safe surgery with good functional outcomes and a decreasing stoma rate where appropriate.

Abstract
Background
Acute calculous cholecystitis (ACC) is the second most frequent surgical condition in emergency departments. The recommended treatment is the early laparoscopic cholecystectomy; however, the Tokyo Guidelines (TG) advocate for different initial treatments in some subgroups of patients without a strong evidence that all patients will benefit from them. There is no clear consensus in the literature about who is the unfit patient for surgical treatment. The primary aim of the study is to identify the risk factors for mortality in ACC and compare them with Tokyo Guidelines (TG) classification.

Methods
Retrospective unicentric cohort study of patients emergently admitted with and ACC during 1 January 2011 to 31 December 2016. The study comprised 963 patients. Primary outcome was the mortality after the diagnosis. A propensity score method was used to avoid confounding factors comparing surgical treatment and non-surgical treatment.

Results
The overall mortality was 3.6%. Mortality was associated with older age (68 + IQR 27 vs. 83 + IQR 5.5; P = 0.001) and higher Charlson Comorbidity Index (3.5 + 5.3 vs. 0+2; P = 0.001). A logistic regression model isolated four mortality risk factors (ACME): chronic obstructive pulmonary disease (OR 4.66 95% CI 1.7–12.8 P = 0.001), dementia (OR 4.12; 95% CI 1.34–12.7, P = 0.001), age > 80 years (OR 1.12: 95% CI 1.02–1.21, P = 0.001) and the need of preoperative vasoactive amines (OR 9.9: 95% CI 3.5–28.3, P = 0.001) which predicted the mortality in a 92% of the patients. The receiver operating characteristic curve yielded an area of 88% significantly higher that 68% (P = 0.003) from the TG classification. When comparing subgroups selected using propensity score matching with the same morbidity and severity of ACC, mortality was higher in the non-surgical treatment group. (26.2% vs. 10.5%).

Conclusions
Mortality was higher in ACC patients treated with non-surgical treatment. ACME identifies high-risk patients. The validation to ACME with a prospective multicenter study population could allow us to create a new alternative guideline to TG for treating ACC.
