Authors: Sobiatin E , Tibrani M , Aznam N , Saputra A T , Fatharani M 
Published: January 2020

Abstract
Learning science is not just for memorizing concepts and materials, but students are expected to be able to apply science in everyday life. The approach that can be used in learning science and making students accustomed to science in their lives is a contextual approach, where students will learn science very interestingly, through direct and meaningful experience. Nowadays natural science learning does not apply a contextual approach as a whole. Integrating Local Potential with the material or content of natural science is one step that can be done to make learning science meaningful because it is very close to the daily lives of students. This research is a descriptive quantitative study with data collection methods through interviews, observations and also literature studies. The results of the study information that there are 22 local potentials of Palembang with 16 of them having a content of natural sciences so that they meet the criteria for being a source of learning and 6 others do not have a significant natural sciences content. The content of science that can be taught through local potential includes material in grades VII, VIII and IX of Junior High School.
Efficacy of cool roofs at reducing pedestrian-level air temperature during projected 21st century heatwaves in Atlanta, Detroit, and Phoenix (USA)
Authors: Broadbent Ashley M , Krayenhoff E Scott , Georgescu Matei 
Published: January 2020

Abstract
The air temperature cooling impacts of infrastructure-based adaptation measures in expanding urban areas and under changing climatic conditions are not well understood. We present simulations conducted with the Weather Research and Forecasting (WRF) model, coupled to a multi-layer urban model that explicitly resolves pedestrian-level conditions. Our simulations dynamically downscale global climate projections, account for projected urban growth, and examine cooling impacts of extensive cool roof deployment in Atlanta, Detroit, and Phoenix (USA). The simulations focus on heatwave events that are representative of start-, middle-, and end-of-century climatic conditions. Extensive cool roof implementation is projected to cause a maximum city-averaged daytime air temperature cooling of 0.38 °C in Atlanta; 0.42 °C in Detroit; and 0.66 °C in Phoenix. We propose a means for practitioners to estimate the impact of cool roof treatments on pedestrian-level air temperature, for a chosen roof reflectivity, with a new metric called the Albedo Cooling Effectiveness (ACE). The ACE metric reveals that, on average, cool roofs in Phoenix are 11% more effective at lowering pedestrian-level air temperature than in Atlanta, and 30% more effective than in Detroit. Cool roofs remain similarly effective under future heatwaves relative to contemporary heatwaves for Atlanta and Detroit, with some indication of increased effectiveness under future heatwaves for Phoenix. By highlighting the underlying factors that drive cooling effectiveness in a trio of cities located in different climatic regions, we demonstrate a robust framework for estimating the pedestrian-level cooling impacts associated with reflective roofs without the need for computationally demanding simulations.

Published: January 2020

Abstract

Background
Sepsis is the leading cause of intensive care unit (ICU) admission. The purpose of this study was to explore the prognostic value of the Sequential Organ Failure Assessment (SOFA) score, the Acute Physiological and Chronic Health Evaluation II (APACHE II) score, and procalcitonin (PCT), albumin (ALB), and lactate (LAC) levels in patients with sepsis.

Methods
Consecutive adult patients with suspected or documented sepsis at ICU admission were recruited. Their basic vital signs and related auxiliary examinations to determine their PCT and ALB levels and APACHE II score were recorded at ICU admission, and their LAC levels and SOFA scores were recorded for one week after admission. The influence of these variables on hospital mortality was evaluated. Logistic regression was used to derive the Sepsis Hospital Mortality Score (SHMS), a prediction equation describing the relationship between predictors and hospital mortality. The median survival time was calculated by the Kaplan–Meier method. In the validation group, the kappa value was calculated to evaluate the stability of the derived formula.

Results
This study included 894 sepsis patients admitted to 18 ICUs in 16 tertiary hospitals. Patients were randomly assigned to an experimental group (626 cases) and validation group (258 cases). In addition, a nonsurvival group (248 patients) of the experimental group was established according to the outcome at the time of discharge. The hospital mortality rate in the experimental group was 39.6% (248/626). Univariate and multivariate regression analyses revealed that the APACHE II score (odds ratio [OR] = 1.178), △SOFA (OR = 1.186), △LAC (OR = 1.157), and SOFA mean score (OR = 1.086) were independently associated with hospital mortality. The SHMS was calculated as logit(p) = 4.715 – (0.164 × APACHE II) – (0.171 × △SOFA) – (0.145 × △LAC) – (0.082 × SOFA mean). A receiver operating characteristic curve was constructed to further investigate the accuracy of the SHMS, with an area under the curve of 0.851 (95% confidence interval [CI] 0.821–0.882; p &lt; 0.001) for hospital mortality. In the low-risk group and high-risk groups, the corresponding median survival times were 15 days and 11 days, respectively.

Conclusion
The APACHE II score, △SOFA, △LAC and SOFA mean score were independently associated with hospital mortality in sepsis patients and accurately predicted the hospital mortality rate and median survival time. Data on the median survival time in sepsis patients could be provided to clinicians to assist in the rational use of limited medical resources by facilitating prudent resource allocation.

Survival of South African patients on renal replacement therapy
Authors: Jardine Thabiet , Wong Esther , Steenkamp Retha , Caskey Fergus J , Davids Mogamat Razeen 
Published: January 2020

AbstractBackgroundThe majority of South Africans rely on a resource-constrained public healthcare sector, where access to renal replacement therapy (RRT) is strictly rationed. The incidence of RRT in this sector is only 4.4 per million population (pmp), whereas it is 139 pmp in the private sector, which serves mainly the 16% of South Africans who have medical insurance. Data on the outcomes of RRT may influence policies and resource allocation. This study evaluated, for the first time, the survival of South African patients starting RRT based on data from the South African Renal Registry.MethodsThe cohort included patients with end-stage kidney disease who initiated RRT between January 2013 and September 2016. Data were collected on potential risk factors for mortality. Failure events included stopping treatment without recovery of renal function and death. Patients were censored at 1 year or upon recovery of renal function or loss to follow-up. The 1-year patient survival was estimated using the Kaplan–Meier method and the association of potential risk factors with survival was assessed using multivariable Cox proportional hazards regression.ResultsThe cohort comprised 6187 patients. The median age was 52.5 years, 47.2% had diabetes, 10.2% were human immunodeficiency virus (HIV) positive and 82.2% had haemodialysis as their first RRT modality. A total of 542 patients died within 1 year of initiating RRT, and overall 1-year survival was 90.4% [95% confidence interval (CI) 89.6–91.2]. Survival was similar in patients treated in the private sector as compared with the public healthcare sector [hazard ratio 0.93 (95% CI 0.72–1.21)]. Higher mortality was associated with older age and a primary renal diagnosis of ‘Other’ or ‘Aetiology unknown’. When compared with those residing in the Western Cape, patients residing in the Northern Cape, Eastern Cape, Mpumalanga and Free State provinces had higher mortality. There was no difference in mortality based on ethnicity, diabetes or treatment modality. The 1-year survival was 95.9 and 94.2% in HIV-positive and -negative patients, respectively. One-fifth of the cohort had no data on HIV status and the survival in this group was considerably lower at 77.1% (P &lt; 0.001).ConclusionsThe survival rates of South African patients accessing RRT are comparable to those in better-resourced countries. It is still unclear what effect, if any, HIV infection has on survival.

Abstract

Background and Aim
It is unclear whether vedolizumab therapy can be discontinued in patients with inflammatory bowel disease [IBD] after achieving steroid-free clinical remission. The aim was to assess the risk of relapse after vedolizumab therapy was discontinued.

Methods
This was a retrospective observational study, collecting data from 21 tertiary centres affiliated with the GETAID from January 2017 to April 2019. Consecutive patients with IBD, who were in steroid-free clinical remission for at least 3 months and were treated with vedolizumab for at least 6 months, were included at the time of vedolizumab discontinuation.

Results
A total of 95 patients [58 with Crohn’s disease] discontinued vedolizumab after a median duration of therapy of 17.5 [10.6–25.4] months. After a median follow-up period of 11.2 [5.8–17.7] months, 61 [64%] patients experienced disease relapse. The probabilities of relapse-free survival were 83%, 59%, and 36% at 6, 12, and 18 months, respectively. According to the multivariate analysis, a C-reactive protein level less than 5 mg/L at vedolizumab discontinuation (hazard ratio [HR] = 0.56, 95% confidence interval [CI] [0.33–0.95], p = 0.03) and discontinuation due to patients’ elective choice (HR = 0.41, 95% CI [0.21–0.80], p = 0.009) were significantly associated with a lower risk of relapse. Re-treatment with vedolizumab was noted in 24 patients and provided steroid-free clinical remission in 71% and 62.5% at Week 14 and after a median follow-up of 11.0 [5.4–13.3] months, respectively, without any infusion reactions.

Conclusions
In this retrospective study, two-thirds of patients with IBD treated with vedolizumab experienced relapse within the first year after vedolizumab discontinuation. Re-treatment with vedolizumab was effective in two-thirds of patients.
‘Ut cantus consonet cum verbis’: transformations of sound and sense in Paolo da Firenze’s Lena, virtù e speranza
Authors: Lopatin Mikhail 
Published: January 2020

Abstract
This article explores the topos of transformation/metamorphosis and its role in creating unusually fluid and ambiguous scenarios of musico-textual behaviour in Trecento and Quattrocento song. Examining Paolo da Firenze’s ballata Lena, virtù e speranza, I show how transformation spreads from the surface level of specific poetic motifs and musical gestures to the very core of music’s relation to its text and text’s relation to its music. In this analysis, my goal is to follow the trajectory of one specific word (‘mutatio’) as it passes through various theoretical filters on its way from the textual to the musical medium (or back), creating new and often unexpected meanings realized in a musical setting.
