Authors: Galeana-Cruz Selenne 
Published: August 2021

El texto trata acerca del estudio de la vivienda reconstruida y su entorno urbano, cuyo objetivo es valorarla habitabilidad obtenida. El motivo de la reconstrucción atañe al proceso de reparación o nueva construcción de una vivienda que ha sido dañada o destruida por un fenómeno natural. El tema se aborda a partir de las dimensiones físico ambiental y social, con el uso de metodología mixta, a saber, observación directa, entrevista y encuesta: para la asignación de valores se ajusta un método a partir de los atributos como el acceso a agua potable, el acceso a saneamiento básico, el espacio suficiente para vivir, la durabilidad de la vivienda y la tenencia segura, en conjunto con las jerarquías fisiológicas, de seguridad y pertenencia social. El estudio se llevó a cabo en Jojutla, Morelos, México, entidad con afectaciones por un sismo ocurrido en 2017. En la actualidad, la vivienda reconstruida y su entorno urbano proporcionan habitabilidad básica, debido a que se han realizado reparaciones a la infraestructura que distribuye los servicios urbanos y la red de saneamiento, alo que se suma una accesibilidad adecuada al equipamiento, aunque subsiste el problema de la inseguridad social. Si bien, se ha intervenido para el mejoramiento físico de los espacios habitables de la vivienda, la necesidad de un área para actividad económica es un indicador pendiente por resolver.
Accuracy and precision of visual and auditory stimulus presentation in virtual reality in Python 2 and 3 environments for human behavior research
Authors: Tachibana Ryo , Matsumiya Kazumichi 
Published: August 2021

AbstractVirtual reality (VR) is a new methodology for behavioral studies. In such studies, the millisecond accuracy and precision of stimulus presentation are critical for data replicability. Recently, Python, which is a widely used programming language for scientific research, has contributed to reliable accuracy and precision in experimental control. However, little is known about whether modern VR environments have millisecond accuracy and precision for stimulus presentation, since most standard methods in laboratory studies are not optimized for VR environments. The purpose of this study was to systematically evaluate the accuracy and precision of visual and auditory stimuli generated in modern VR head-mounted displays (HMDs) from HTC and Oculus using Python 2 and 3. We used the newest Python tools for VR and Black Box Toolkit to measure the actual time lag and jitter. The results showed that there was an 18-ms time lag for visual stimulus in both HMDs. For the auditory stimulus, the time lag varied between 40 and 60 ms, depending on the HMD. The jitters of those time lags were 1 ms for visual stimulus and 4 ms for auditory stimulus, which are sufficiently low for general experiments. These time lags were robustly equal, even when auditory and visual stimuli were presented simultaneously. Interestingly, all results were perfectly consistent in both Python 2 and 3 environments. Thus, the present study will help establish a more reliable stimulus control for psychological and neuroscientific research controlled by Python environments.
Europa Clipper Preparatory Photometry to Constrain Surface Properties

Published: August 2021

Abstract
We infer the surface reflectance properties of Europa using multispectral data sets available from previous missions. We use 21 full-disk images of Europa from Voyager’s Imaging Science System, Galileo’s Solid State Imaging, and New Horizons’ Long Range Reconnaissance Imager at differing observation geometries (10°–128° (phase angle)) to compute disk-integrated surface-scattering properties over various geologic units. The derived empirical photometric models will serve the practical goals of data acquisition, aid in the calculation of instrument integration times, and facilitate quick-look data products for images acquired by Europa Clipper and other future missions to Europa. We use the Minneart and Lommel–Seeliger plus Lambert reflectance models to constrain the photometric parameters of Europa’s surface. We find that the surface albedo parameter, B
0, in the Minneart function gradually decreases with increasing phase angles. We also note that the photometric properties of Europa (geometric albedo at 0.47 μm is 0.72 on the leading side and 0.62 on the trailing side) require a significant “Lambert” term (A < 1) in the Lommel–Seeliger plus Lambert reflectance model. We also observe that the photometric parameters are not highly dependent on the geologic terrain type despite their visibly different albedos.

Introduction: Several micro ribonucleic acids (miRNAs) are deregulated in hepatocellular carcinoma (HCC). Others are linked to clinical pathological features of HCC. The goal of this study was to investigate whether miRNA-21 and miRNA-215 gene expression could be used as a non-invasive diagnostic tool to diagnose HCC.
Methodology: The gene expression of mature miRNA -21 and miRNA -215 in serum was analysed retrospectively using singleplex TaqMan two-step stem-loop quantitative real-time reverse-transcription PCR in 40 patients with HCC, 40 with chronic hepatitis C virus (HCV) with cirrhosis and 40 apparently healthy controls.
Results: Expression of miRNA -21 was significantly more down regulated in patients with HCC than in those with non-cirrhotic HCV (P = 0.007; odds ratio = 5; 95% confidence interval 1.6–15.4). The receiver operating curve analysis of the ability of miRNA-21 expression to discriminate between HCC and non-cirrhotic HCV revealed an area under the curve of 0.712 with 70% sensitivity and 68% specificity at a cut-off of ≤ 1.4468. Thus, the expression level of miRNA -21 could discriminate HCC from non-cirrhotic HCV. Significant positive correlation was observed between expression levels of microRNA-21 and miRNA -215 (r = 0.783, p < 0.001), but no association was observed between expression level of miR-215 and HCC or chronic HCV (p = 0.474).
Conclusions: MiRNA-21 may be a useful, non-invasive tool for diagnosing HCC. Non-cirrhotic HCV patients have five times the risk of developing HCC when the miRNA -21 level ≤ 1.4468.

Introduction: Aspergillus exhibits a wide variation of susceptibility against antifungals according to genetic and environmental factors. Identification to the species level is necessary for appropriate treatment. Our objective was to determine the Aspergillus species involved in invasive pulmonary aspergillosis (IPA) among ICU patients in Jakarta, Indonesia.
Methodology: The incidence of IPA in ICU patients at six hospitals in Jakarta from October 2012 – January 2015 was investigated. It involved a collection of endotracheal aspirates (ETA), nasal swabs and environmental samples around the hospitals, phenotypic screening, molecular characterization, and antifungal susceptibility testing.
Results: Of the 405 patients investigated, 31 patients (7.7%) were diagnosed with putative IPA, from whom 45 Aspergillus isolates were collected. Aspergillus isolates were identified from pulmonary secretions in 24 patients, from nasal swabs in 7 patients and from both pulmonary secretions and nasal swabs in 7 patients. The phenotypic method showed 33 isolates of Aspergillus flavus (73.4%), nine Aspergillus fumigatus (20%), two Aspergillus niger (4.4%), and one Aspergillus nidulans (2.2%) isolate. Molecular identification showed 27 isolates of A. flavus (60.0%), eight isolates of A. fumigatus (17.8%), two isolates of A. niger (4.4%) and one isolate of A. nidulans (2.2%), while seven isolates (15.6%) were cryptic species or mixed isolates.
Conclusions: Susceptibility testing showed all isolates were susceptible to amphotericin B, azoles and micafungin. Aspergillus flavus was the main causative organism in IPA cases in Jakarta, followed by A. fumigatus.

Introduction: Kenya adopted the World Health Organization’s recommendation of community case management of malaria (CCMM) in 2012. Trained community health volunteers (CHVs) provide CCMM but information on quality of services is limited. This study aimed to establish determinants of quality of service of CCMM conducted by CHVs.
Methodology: A cross-sectional survey was conducted in November 2016 in Bungoma County, Kenya. Data were collected through observing CHVs perform routine CCMM and through interviews of CHVs using structured questionnaires. A ≥ 75% score was considered as quality provision. Descriptive statistics were performed to describe basic characteristics of the study, followed by Chi-Square test and binary logistic regression to examine the differences and associations between the categorical variables.
Results: A total of 147 CHVs participated; 62% of CHVs offered quality services. There was a direct association between quality of services and stock-outs of artemether-lumefantrine (AL), stock-outs of malaria rapid diagnostic tests (RDT) and support supervision. CHVs who were supervised during the year preceding the assessment were four times more likely to perform better than those not supervised (uOR 4.2, 95% CI: 1.38-12.85). CHVs with reliable supplies of AL and RDT kits performed three times better than those who experienced stock outs (uOR = 3.2, 95% CI: 1.03-10.03 and 3.3, 95% CI: 1.63-6.59 respectively). Biosafety and documentation were the most poorly performed.
Conclusions: The majority of CHVs offered quality CCMM services despite safety gaps. Safety, continuous supplies of RDT, AL and supervision are essential for quality performance by CHV in delivering CCMM.
Retail chicken meats as potential sources of Clostridioides difficile in Al-Jouf, Saudi Arabia
Authors: Taha Attia Ahmed Elsayed 
Published: August 2021

Introduction: Presence of Clostridioides difficile in stool of food birds and animals is a risk for contamination of their meats to become potential sources of human infection. The main virulence factors of C. difficile are its resistance to antibiotics, production of toxins and spores. As far as I know, this is the first study to evaluate C. difficile prevalence in chicken meats, its toxigenic activities and antibiotics sensitivity patterns in Al-Jouf, Saudi Arabia.
Methodology: Totally, 250 raw chicken meat samples were examined. Standard microbiological and biochemical procedures were used for C. difficile isolation and identification. The suspected colonies were tested by L-proline and C. difficile test kits then confirmed by Vitek 2 compact system. Xpect C. difficile toxin A/B test was used to detect A/B toxins production. Antibiotics susceptibility patterns were detected by Epsilon tests.
Results: C. difficile was isolated from 11/250 (4.40%) chicken meat samples; 5/65 (7.69%) legs, 3/65 (4.61%) thighs, 2/60 (3.33%) wings and 1/60 (1.67%) breasts (p = 0.4). All isolates were non-toxigenic. Although all isolates were vancomycin sensitive, some isolates were intermediate/resistant to metronidazole, tetracycline, clindamycin or moxifloxacin antibiotics with variable degrees.
Conclusions: C. difficile might contaminate retail chicken meats. Although low level of contamination by non-toxigenic strains was detected, chicken meats should be investigated as C. difficile infection sources for humans especially elders, immune-compromised and long terms wide spectrum antibiotics-used persons. Decreased sensitivity of C. difficile to antibiotics is emerging.

Introduction: Annual seasonal influenza vaccination in healthcare workers prevents nosocomial transmission to patients, coworkers, and visitors, and reduces absenteeism. This study aimed to describe knowledge, attitudes, and practices (KAP) of seasonal influenza vaccine among public healthcare workers attending patients in Costa Rica.
Methodology: We conducted a cross-sectional survey of healthcare personnel attending patients in public hospitals in 2017–2018. Frequency distributions of demographics, vaccination KAP, sources of information, clinical manifestations and reasons for non-vaccination were reported. Logistic regression was used to analyze associations between exposures of interest (demographics, sources of information, knowledge, attitudes towards vaccination) and self-reported influenza vaccination.
Results: We surveyed 747 healthcare workers in 2017–2018. Of 706 participants who knew their vaccination status, 55.7% were vaccinated for seasonal influenza. Only 20.7% of participants knew the influenza vaccine was an inactivated virus, and 94.6% believed the vaccine causes flu-like symptoms. Factors associated with current influenza vaccination were vaccination in previous year (aOR: 8.13; 95% CI: 5.65–11.71) and believed influenza vaccination may be harmful (aOR: 0.62; 95% CI: 0.44–0.89). Reasons for non-vaccination included fear of adverse effects and access limitations.
Conclusions: Suboptimal influenza vaccination among healthcare workers may be attributed to misconceptions about the vaccine and limited engagement strategies focusing on healthcare workers. Appropriate interventions are needed to increase healthcare worker vaccination rates and improve their knowledge and beneficence, which would improve patient safety in hospitals.

Published: August 2021

Aim:
To validate the Acuros® XB (AXB) algorithm in Eclipse treatment planning system (TPS) for RapidArc™ (RA) technique following the software upgrades.

Materials and Methods:
A Clinac-iX (2300CD) linear accelerator and Eclipse TPS (Varian Medical System, Inc., Palo Alto, USA) was used for commissioning of AXB algorithm using a 6 megavolts photon beam. Percentage depth dose (PDD) and profiles for field size 2 cm × 2 cm, 4 cm × 4 cm, 6 cm × 6 cm, 10 cm × 10 cm, 20 cm × 20 cm, 30 cm × 30 cm to 40 cm × 40 cm were taken. AXB calculated PDDs and profiles were evaluated against the measured and analytical anisotropic algorithm (AAA)-calculated PDDs and profiles. Test sites recommended by American Association of Physicists in Medicine task group (AAPM TG)-119 recommendation were used for RA planning and delivery verification using AXB algorithm.

Results:
Dosimetric analysis of AXB calculated data showed that difference between calculated and measured data for PDD curves were maximum <1% beyond the depth of dose maximum and computed profiles in central region matches with maximum <1% for all considered field sizes. Ion-chamber measurements showed that the average confidence limit (CLs) was 0.034 and 0.020 in high-gradient and 0.047 and 0.042 in low-gradient regions, respectively, for AAA and AXB calculated RA plans. Portal measurements show the average CLs were 2.48 and 2.58 for AAA and AXB-calculated RA plans, with gamma passing criteria of 3%/3 mm.

Conclusions:
AXB shows excellent agreement with measurements and AAA calculated data. The CLs were consistent with the baseline values published by TG-119. AXB algorithm has the potential to perform photon dose calculation with comparable fast calculation speed without negotiating the accuracy. AAPM TG-119 was successfully implemented to access the proper configuration of AXB algorithm following the TPS upgrade.
The effect of fluoride gel on tensile properties, surface morphology and chemical composition of two types of orthodontic wires (an in-vitro study)
Authors: Taqa Amer A. , Al-Hafidh Nada Nashee , Al-Abbood Mohammed T. Sulaiman 
Published: August 2021

OBJECTIVE:
Stainless steel and nickel-titanium wires are commonly used in fixed orthodontic appliances. Orthodontists often prescribe fluoride gel to avoid demineralization of teeth. This study investigated the effect of acidulated phosphate fluoride gel on the tensile properties, surface morphology and surface chemical composition of stainless steel and nickel-titanium wires.

METHODS:
Forty samples of stainless steel and nickel-titanium wires were examined, twenty for each type. Each wire type was divided into four subgroups. The first subgroup was not immersed in fluoride gel and considered as control, while the other three subgroups were immersed in 10 mL of fluoride gel for different periods of time. Then, the wires were removed from the gel, rinsed in a distilled water and left to dry. The ultimate tensile force of each wire was measured using a tensile testing machine. Scanning electron microscope (SEM) and energy-dispersive X-ray spectroscopy (EDX) were used to examine the control and 24 h immersed subgroups.

RESULTS:
One-way analysis of variance ANOVA showed that there were no significant differences in the ultimate tensile forces between control and fluoride-treated subgroups (P = 0.172 for SS wires and P = 0.672 for NiTi wires). However, changes in the surface morphology and elemental composition of wires were shown by the SEM and EDX.

CONCLUSIONS:
Although immersion of stainless steel and nickel-titanium wires in the fluoride gel did not affect their tensile properties, however, surface deterioration was evident. So, further investigations are recommended to study the effect of these changes on the oral health of patients.
