Published: January 2022

Introducción: En países con escasos recursos, la disección como medio para enseñar anatomía no es factible a menudo, debido a la disponibilidad limitada de cuerpos, alto costo y riesgos de seguridad. En Nicaragua, la anatomía y radiología se estudia de forma  independiente.Objetivo: El objetivo del estudio es explorar el impacto (desempeño y percepciones) del uso de imágenes radiológicas en la enseñanza de anatomía en estudiantes de medicina de un país con bajos recursos. Método: Se implementó un curso extraescolar de anatomía radiológica a estudiantes de medicina de tercer (n=87) y sexto (n=67) año. Se aplicó una pre/posprueba y una encuesta posterior al curso. Se calcularon la media, mediana y desviación estándar, con un nivel de intervalo de confianza del 95%.Resultados: Las percepciones de ambos grupos fueron similares. Relacionado a las técnicas radiológicas: TC (82.8% junior y 94% senior) fue la más útil; y la ecografía la menos (49.4% junior y 67.2% senior). Aceptación de recursos didácticos: guía de estudio (73.6% junior y 82.1% senior) y atlas digital interactivo (69% junior y 80.6% senior) obtuvieron la puntuación más alta; mientras que los libros impresos (36.8% junior y 59.7% senior) obtuvieron la puntuación más baja. Los puntajes previos a la prueba fueron similares en ambos grupos (media  de respuesta correcta 7.98 junior y 8.22 senior). En la posprueba, la media de aciertos aumentó en ambos grupos: 32.03 para junior y 32.82 para senior (p=0.000).Conclusiones: La integración de la radiología y la anatomía tiene un impacto positivo en los estudiantes de medicina, debe implementarse a través de un enfoque de aprendizaje autodirigido, y considerarse complementaria en el plan de estudios médico como una buena alternativa para enseñar anatomía en países donde la disección no es factible.
Radioactive heat production characterization of Ar-Rassafeh Badyieh area (area-2), Syria by using aerial gamma ray spectrometric and fractal modeling techniques
Authors: Asfahani Jamal
Published: January 2022

Aerial gamma-ray spectrometric technique is used herein to evaluate the radioactive heat production (HP) of Ar-Rassafeh Badyieh Area (Area-2), Syria. The nine already established lithological scored units of Area-2 have been separately characterized for the heat production HP parameter. The Concentration-number (C-N) model and the log-log plots associated with fractal technique are proposed and applied as a new approach to map the measured equivalent uranium (eU), the equivalent thorium (eTh), and potassium (K%) and the computed heat production (HP) of Area-2. The HP of Area-2 varies between a minimum of 0.06 and a maximum of 4.28 ?w/m3 with an average of 0.548 ?w/m3 and a standard deviation of 0.27?w/m3. The highest observed HP values are related to the phosphatic environments represented by two lithological scored units A and B.

This substantiates the practical relevance of the study of container depots in railway transport. Another task is the development of mathematical models of the interconnection of the parameters of the container depot. Currently, there are several different methods and methods for calculating and determining the parameters of container sites, the analysis of which is given in the article. However, there is a need to supplement, clarify and unify the existing methods for calculating all kinds of parameters for a container depot, which justifies the theoretical relevance of the study. Connections with which the purpose of the article is to develop a methodology for the reliable determination of the most rational values of the parameters of the container terminal, thereby improving and increasing the level of customer service in transport in general. Research methods are based on a systematic analysis and generalization of existing methods and methods for calculating the capacity of container depots. The results of the study are presented by the developed methodology for determining the capacity of warehouses on railway transport, which provides a more qualified calculation and selection of container depot parameters, as well as a decrease in erroneous design decisions and an increase in the reliability of projects for the development and improvement of railway transport and the transport network as a whole.

The paper presents an analysis of the parameter obtained by remote sensing of the planet Earth, the normalized vegetation index (NDVI index). The results of assessing the impact of the index on the occurrence of fires in a certain area are presented. Using the example of statistical data for the Krasnoyarsk Territory, the index values for two periods of spring and summer were obtained, and the influence of NDVI values on the change in the probability of a forest fire was estimated. Static data on the index were selected from the «data lake» of the Ministry of Emergency Situations of Russia, data is collected from 2014 to the present, and data on thermal points from 2012. The consequences after wildfires will cause significant damage to forestry in Russia, and to the environment as a whole. Therefore, the allocation of previously known areas with a high probability of a natural fire will not only improve preventive measures for prevention, but will also make it possible to prevent most of the consequences. This article considers one of the parameters obtained by remote sensing of the Earth NDVI of its change before and after the event in question (natural fire).

Abstract. The use of household insecticides is an alternative solution to prevent mosquito bites.Most of the household insecticides sold in Indonesia have pyrethroid active ingredients, permethrin,which is available in the aerosol formulation. Inappropriate use of household insecticides can reducemosquito susceptibility. The objectives of this study are to describe the use of household insecticidesand susceptibility of Aedes sp. against permethrin in Sorosutan Yogyakarta. This study used a crosssectionalsurvey design. This study was conducted in December 2018–April 2019 in 354 householdsin Sorosutan which were randomly selected based on proportional sampling. Interviews about thehousehold insecticides were conducted with the owner or resident of the house. The susceptibilitytests used impregnated paper with permethrin 0.75%. The survey results showed that 25.14% ofthe houses use household insecticides. The insecticide used were aerosol, electric mosquito repellents,and mosquito coils containing active ingredients of the pyrethroid group, namely dimefl uthrin,transfl uthrin, prallethrin, cypermethrin, and metofl uthrin. The susceptibility test results showed adecrease in mosquito susceptibility where the population of Aedes sp. in Sorosutan has been resistantagainst permethrin. The continuous use of insecticides with pyrethroid active ingredients can developmosquito resistance against permethrin because all pyrethroids have the same mode of action. Thisstudy concludes that only a small proportion (25,14%) of the households used insecticides with theactive ingredients used mainly in the pyrethroid group (dimefl uthrin, transfl uthrin, prallethrin,cypermethrin, and metofl uthrin) and the population of Aedes sp. in Sorosutan has been resistant topermethrin.

Abstract. Tasikmalaya city is a high endemic dengue area which contributes to the high number ofdengue cases in West Java province. This study aims to analyze the geographic distribution patternof dengue infection at the village level and identify high-risk urban villages in Tasikmalaya City. Thisstudy analyzed the surveillance data of dengue cases in 2016–2020 which was routinely managed bythe Tasikmalaya City Health Office. Variables analyzed included date, patient’s name and address(villages). The map data in the form of a shape file (shp.) were obtained from BPS in 2019. The spatialautocorrelation analysis uses two approaches, (the global Moran Index and LISA). The results showedthat DHF cases in the Tasikmalaya city tend to increase in the last 5 years (2016–2020). The highestnumber of annual and monthly dengue cases occurred in 2020, (1,744 cases and 307 cases) withthe incidence rate peaked at 262.6561 per 100,000 population. The global Moran index test using asignificance level of 5 showed that there is a spatial autocorrelation between adjacent sub-districts ofdengue cases in Tasikmalaya city every year for the last 5 years (2016–2020, and cumulative). Thevalue of the global moran index (I) shows a positive correlation between urban villages to the numberof annual dengue cases for the last 5 years and is cumulative. It can be concluded that there aresimilarities in the characteristics of DHF cases in adjacent villages or the relationship between DHFcases tends to be spatially clustered.

Protein folding and unfolding: proline cis - trans isomerization at the c subunits of F 1 F O -ATPase might open a high conductance ion channel
Authors: Nesci Salvatore
Published: January 2022

The c subunits, which constitutes the c-ring apparatus of
the F F -ATPase, could be the main
components of the mitochondrial permeability transition pore (mPTP). The
well-known modulator of the mPTP formation and opening is the
cyclophilin D (CyPD), a peptidyl-prolyl cis- trans
isomerase. On the loop, which connects the two hairpin α-helix of
c subunit, is present the unique proline residue (Pro
) that could be a biological target of CyPD. Indeed,
the proline cis- trans isomerization might provide the
switch that interconverts the open/closed states of the pore by pulling
out the c-ring lipid plug.

Global change drivers such as anthropogenic nutrient inputs
simultaneously alter biodiversity, species composition, and ecosystem
functions such as above ground biomass. These changes are interconnected
by complex feedbacks among extinction, invasion, and shifting relative
abundance. Here, we use a novel temporal application of the Price
equation to separate species richness and biomass change through time
and quantify the functional contributions of species that are lost,
gained, and persist under ambient and experimental nutrient addition in
59 global grasslands. Under ambient conditions, compositional and
biomass turnover was high, but species losses (i.e., local extinctions)
were balanced by gains (i.e. colonization). Under fertilization, there
was biomass loss associated with species loss. Few species were gained
in fertilized conditions over time but those that were, and species that
persisted, contributed to net biomass gains, outweighing biomass loss.
These components of community change are associated with distinct
effects on measures of ecosystem functioning.

Integrating partitioned evapotranspiration data into hydrologic models: vegetation parameterization and uncertainty quantification of simulated plant water use
Authors: Schreiner-McGraw Adam , Ajami Hoori , Anderson Ray , Wang Dong
Published: January 2022

Accurate simulation of plant water use across agricultural ecosystems is
essential for various applications, including precision agriculture,
quantifying groundwater recharge, and optimizing irrigation rates.
Previous approaches to integrating plant water use data into hydrologic
models have relied on evapotranspiration (ET) observations. Recently,
the flux variance similarity approach has been developed to partition ET
to transpiration (T) and evaporation, providing an opportunity to use T
data to parameterize models. To explore the value of T/ET data in
improving hydrologic model performance, we examined multiple approaches
to incorporate these observations for vegetation parameterization. We
used ET observations from 5 eddy covariance towers located in the San
Joaquin Valley, California, to parameterize orchard crops in an
integrated land surface – groundwater model. We find that a simple
approach of selecting the best parameter sets based on ET and T
performance metrics works best at these study sites. Selecting
parameters based on performance relative to observed ET creates an
uncertainty of 27% relative to the observed value. When parameters are
selected using both T and ET data, this uncertainty drops to 24%.
Similarly, the uncertainty in potential groundwater recharge drops from
63% to 58% when parameters are selected with ET or T and ET data,
respectively. Additionally, using crop type parameters results in
similar levels of simulated ET as using site-specific parameters.
Different irrigation schemes create high amounts of uncertainty and
highlight the need for accurate estimates of irrigation when performing
water budget studies.
Genetic Risk Score Enhances Coronary Artery Disease Risk Prediction in Individuals With Type 1 Diabetes

Published: January 2022

OBJECTIVE

Individuals with type 1 diabetes are at a high lifetime risk of coronary artery disease (CAD), calling for early interventions. This study explores the use of a genetic risk score (GRS) for CAD risk prediction, compares it to established clinical markers, and investigates its performance according to the age and pharmacological treatment.

RESEARCH DESIGN AND METHODS

This study in 3,295 individuals with type 1 diabetes from the Finnish Diabetic Nephropathy Study (467 incident CAD, 14.8 years follow-up) used three risk scores: a GRS, a validated clinical score, and their combined score. Hazard ratios (HR) were calculated with Cox regression, and model performances were compared with the Harrell C-index (C-index).

RESULTS

A HR of 6.7 for CAD was observed between the highest and the lowest 5th percentile of the GRS (P = 1.8 × 10−6). The performance of GRS (C-index = 0.562) was similar to HbA1c (C-index = 0.563, P = 0.96 for difference), HDL (C-index = 0.571, P = 0.6), and total cholesterol (C-index = 0.594, P = 0.1). The GRS was not correlated with the clinical score (r = −0.013, P = 0.5). The combined score outperformed the clinical score (C-index = 0.813 vs. C-index = 0.820, P = 0.003). The GRS performed better in individuals below the median age (38.6 years) compared with those above (C-index = 0.637 vs. C-index = 0.546).

CONCLUSIONS

A GRS identified individuals at high risk of CAD and worked better in younger individuals. GRS was also an independent risk factor for CAD, with a predictive power comparable to that of HbA1c and HDL and total cholesterol, and when incorporated into a clinical model, modestly improved the predictions. The GRS promises early risk stratification in clinical practice by enhancing the prediction of CAD.
Association Between Change in Accelerometer-Measured and Self-Reported Physical Activity and Cardiovascular Disease in the Look AHEAD Trial
Authors:   Look AHEAD Study Group
Published: January 2022

OBJECTIVE

To conduct post hoc secondary analysis examining the association between change in physical activity. Measured with self-report and accelerometry, from baseline to 1 and 4 years and cardiovascular disease (CVD) outcomes in the Look AHEAD Trial.

RESEARCH DESIGN AND METHODS

Participants were adults with overweight/obesity and type 2 diabetes with physical activity. Data at baseline and year 1 or 4 (n = 1,978). Participants were randomized to diabetes support and education or intensive lifestyle intervention. Measures included accelerometry-measured moderate-to-vigorous physical activity (MVPA), self-reported physical activity, and composite (morbidity and mortality) CVD outcomes.

RESULTS

In pooled analyses of all participants, using Cox proportional hazards models, each 100 MET-min/week increase in accelerometry-measured MVPA from baseline to 4 years was associated with decreased risk of the subsequent primary composite outcome of CVD. Results were consistent for changes in total MVPA (hazard ratio 0.97 [95% CI 0.95, 0.99]) and MVPA accumulated in ≥10-min bouts (hazard ratio 0.95 [95% CI 0.91, 0.98]), with a similar pattern for secondary CVD outcomes. Change in accelerometry-measured MVPA at 1 year and self-reported change in physical activity at 1 and 4 years were not associated with CVD outcomes.

CONCLUSIONS

Increased accelerometry-measured MVPA from baseline to year 4 is associated with decreased risk of CVD outcomes. This suggests the need for long-term engagement in MVPA to reduce the risk of CVD in adults with overweight/obesity and type 2 diabetes.

Objective: Longitudinal studies on barriers to applying for rehabilitation in Germany are lacking in light of the suspected underutilization of rehabilitation services. The aim of this study was to examine application behaviour in persons with disabling back pain and to identify relevant predictors for making an application. Design: A prospective cohort study with randomized sampling of insurants in the German Pension Insurance, using a questionnaire at baseline and follow-up with linked administrative data for 1.5 years. Subjects/patients: Employed persons (age range 45–59 years) with a high degree of limitations due to back pain and a self-reported risk of permanent work disability (not applied for disability pension, no medical rehabilitation within the last 4 years). Methods: Multivariable Cox regression was used to examine the influence of pre-selected variables on making an application in the follow-up period. Results: Of 690 persons, only 12% applied for rehabilitation. Predictors for making an application were: support from physicians (hazard ratio (HR)=2.24; 95% confidence interval (95% CI) 1.32–3.80), family, and friends (HR=1.67; 95% CI 1.02–2.73), more pain-related disability days (HR=1.02; 95% CI 1.01–1.03), and worse work ability (HR=0.86; 95% CI 0.75–0.97). An intention to apply at baseline mediated the effect of family and physician support on the application. Conclusion: The low number of applications for rehabilitation despite disabling back pain indicates access barriers to, and underuse of, medical rehabilitation.

As the city growing bigger in line with population, urban economics will be alongside daily transportation. The high number of daily transportation need to be accommodated with urban public transport services. In 2011, Bandar Lampung City Government provide Bus Rapid Transit (BRT) as a mass public transportation service in Bandar Lampung City. But, after about 9 (nine) years, the number of Bus Rapid Transit (BRT) route services is drop. The sustainability is questioned due to the number of passengers and operating routes continuously down, starting from 7 (seven), to 3 (three) then today is only 1 (one) left. But the city without public transportation service certainly become a bad precedent. Rajabasa Route-Panjang is the only Bus Rapid Transit (BRT) service exist. The vehicle operating costs calculation shows about IDR 648,101,870 / year, IDR 1,874,252 / day, IDR 312,375 / trip, IDR 8,255 / km, IDR 156,188 / hour and IDR 3, IDR 124 / seat needs to be provided by the regulator/government to ensure the service.

Data geospasial (spasial) jalan telah menjadi kebutuhan penting yang tak terhindarkan dalam kehidupan masyarakat saat ini. Data spasial jalan tidak hanya bisa dimanfaatkan dalam perencanaan dan pemantauan pembangunan wilayah namun juga merambah dalam keseharian masyarakat yang terlihat antara lain dari intensifnya penggunaan aplikasi-aplikasi mobile services berbasis data spasial jalan pada perangkat mobile. Oleh karena itu ketersediaan data spasial jalan yang lengkap-akurat-kekinian mutlak adanya. Pembaruan data spasial jalan melalui deteksi dengan penginderaan jauh menggunakan citra satelit resolusi tinggi telah diterima secara luas sebagai bentuk kompromi antara efisiensi biaya dan waktu dengan tingkat akurasi yang diperlukan. Namun kendalanya akses terhadap citra resolusi tinggi ini sangat terbatas. Penelitian ini menggunakan metode mixture tuned matched filtering (MTMF) untuk mendeteksi fraksi piksel jalan aspal pada citra resolusi menengah yaitu Landsat 8 OLI path 127 row 61 subscene sebagian wilayah Kota Padang yang telah terkoreksi ke level topografik. Akurasi metode MTMF diukur melalui uji akurasi deteksi (sensitivity dan specificity) dan uji akurasi posisi (circular error (CE)90). Hasil uji akurasi deteksi menunjukkan sensitivity sebesar 67,51% dan specificity sebesar 53,02%. Hasil uji akurasi posisi menunjukkan nilai CE90 sebesar 45,07.
