Abstract
Background: abortion and stillbirths are the common obstetrics condition in Ethiopia and their effect on the next pregnancy was not well identified in resource limited settings. The aim of the study was to assess the effect of stillbirth and abortion on the next pregnancy.Methods: A prospective cohort study design was implemented. The study was conducted in Mecha demographic surveillance and field research center catchment areas. The data were collected from January 2015 to March 2019. Epi-info software was used to calculate the sample size. The systematic random sampling technique was used to select stillbirth and abortion women. Poison regression was used to identify the predictors of MCH service utilization; descriptive statistics were used to identify the prevalence of blood borne pathogens. The Kaplan Meier survival curve was used to estimate survival to pregnancy and pregnancy related medical disorders.Results: 1091 stillbirth and 3,026 abortion women were followed. Hepatitis B was present in 6% of abortion and 3.2 % of stillbirth women. Hepatitis C was diagnosed in 4.7 % of abortion and 0.3 % of stillbirth women. HIV was detected in 3 % of abortion and 0.8 % of stillbirth women. MCH service utilization was determined by knowledge of contraceptives [IRR 1.29, 95% CI: 1.18-1.42], tertiary education [IRR 4.29, 95% CI: 3.72 -4.96], secondary education. [IRR 3.14, 95% CI: 2.73 -3.61], married women [IRR 2.08, 95% CI: 1.84 -2.34], family size women [IRR 0.67, 95% CI: 1.001 -1.01], the median time of pregnancy after stillbirth and abortion were 12 months. Ante-partum hemorrhage was observed in 23.1 % of pregnant mothers with a past history of abortion cases and post-partum hemorrhage was observed in 25.6 % of pregnant mothers with a past history of abortion.PIDM was observed 14.3 % of pregnant mothers with a past history of stillbirth and pregnancy-induced hypertension was observed in 9.2 % of mothers with a past history of stillbirth.

Authors: Praveena Sarva Mangala , Themudu Sri 
Published: March 2021

Abstract
Malaysia is a tropical country that gets high rainfall throughout the year that can be utilized for various activities including water conservation. Water conservation initiatives in Malaysia are mainly concentrated in commercial and residential buildings but public buildings such as schools have been underutilized. Thus, this study aims to conduct a water conservation initiative in a primary school in Malacca (Malaysia). Water audit were conducted to identify the highest water usage location and the most suitable water conservation method in a school setting. Lastly, the sustainability performance of the rainwater harvesting system was evaluated via the Sustainable Development Analytical Grid (SDAG) assessment tool. Water footprint findings demonstrated that approximately 60% of total water use was due to toilet use. The rainwater harvesting system was selected as this method enables the use of a renewable source (rainwater) and it conveniently fit with the existing building rooftop and plumbing system to engender high sustainability potential and collaboration opportunities. After several months of operation, environmental, social, and economic benefits were observed. Sustainable assessment has indicated that all the six dimensions were well balanced with scores greater than 50% and continued improvements will increase the project’s sustainability in the future. This study approach is generalizable to any school worldwide with a similar water footprint as a water restoration at both local and global contexts to achieve United Nation’s Sustainable Development Goals.

Abstract
Gas stations are one of the most important sources of soil and groundwater contamination in urban areas around the world. In this work, a mathematical model was applied to assess the risk of the physical media contamination. The model is based on the chemical properties of fuels and site-specific hydrological properties. The group of hydrocarbons selected were the monoaromatic: benzene, toluene, ethylbenzene and xylene (BTEX). The mathematical model was used to evaluate the behaviour of each compound in each partitioning phase (dissolved, volatile, solid and non-aqueous liquid phase). Furthermore, mass flux of BTEX reaching groundwater was calculated according to steady flow under two different conditions: (1) considering only sorption and volatilization, and (2) adding biodegradation. In all cases, the total mass of BTEX leachate was greater when biodegradation was not considered. In areas with unsaturated zone thickness greater than two meters, sorption is the main process affecting BTEX transport. Otherwise, when water table is placed at shallower depths, contaminants are predominately dissolved. In all cases, the lowest proportion of BTEX were in the volatile phase. The model presented in this work proved to be an interesting tool to evaluate the behaviour of BTEX in soil and groundwater and its applicability being directly related to environmental and urban management of pollution from gas stations. The methodology applied in this work could be extrapolated to any site of the world with the same problematic. Particularly, the theoretical model allowed to defined zones with high and low risk of contamination in Bahia Blanca, Argentina.

Published: March 2021

Abstract
The present research performed thermal decomposition to synthesize pure zinc oxide (ZnO) and cadmium-doped ZnO (ZnO:Cd) nanorods with ZnO to Cd weight ratios of 93:7, 95:5 and 97:3. Field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and photoluminescence (PL) spectroscopy were performed and current/voltage and current/time measured to determine the optical, structural and morphological characteristics of ZnO and ZnO:Cd. The XRD results suggested the hexagonal wurtzite structure of all the samples and the successful incorporation of Cd into the ZnO structures. This incorporation caused a spherical to rod-like change in the shape of the nanostructures. An intense and sharp peak was observed at 380 nm (3.26 eV) in the UV region of the PL spectra of all the samples. A UV photodetector fabricated on the basis of ZnO and ZnO:Cd nanorods with a metal-semiconductor-metal configuration showed the significant photocurrent and photosensitivity of the ZnO:Cd samples in the UV photodetection application. The sensitivity of the fabricated ZnO photodetectors with Cd percentages of 0, 3, 5 and 7% was respectively obtained as 110.62, 463.28, 762.40 and 920.30. The fastest photoresponse, with a rise and decay time of 2.5 and 4 s, respectively, was associated with the sample doped with 5% Cd.

Published: March 2021

Abstract
In later years, numerous viable photocatalysts have been created in order to illuminate the issues of natural toxins. In this work, heterostructured photocatalysts Ag3VO4/g-C3N4 were prepared by effortless hydrothermal route in order to anchor Ag3VO4 on the surface of the g-C3N4 nanosheets. The prepared samples were fairly characterized using X-ray diffraction (XRD), Energy dispersive analysis of X-rays (EDAX), Scanning electron microscopy (SEM), Transmission electron microscopy (TEM), UV-vis diffuse reflectance spectroscopy (UV-DRS), photoluminescence, and X-ray photoelectron spectroscopy (XPS) techniques. The photocatalytic activity of the samples was evaluated by degrading malachite green (MG) and 2,4 dimethyl phenol (DMP) in aqueous solution under visible light irradiation. Compared with Ag3VO4 and g-C3N4, the heterojuncted photocatalyst 50 wt% Ag3VO4/g-C3N4 exhibits the best activity such as high degradation efficiency (99%), high apparent constant (0.0923 min− 1) and long term stability towards DMP under visible light irradiation. The development of a phase scheme heterojunction between Ag3VO4 and g-C3N4 improved the photocatalytic efficiency of Ag3VO4/g-C3N4 composites. Furthermore, the porous structure of g-C3N4 and the effect of Ag surface plasmon resonance (SPR) speed up the isolation and transfer of electron-hole pairs, reducing the likelihood of recombination.

Abstract
Background: Clinical practice guideline (CPG)-consistent care improves patient outcomes, but CPG implementation is poor. Little is known about CPG implementation in pediatric oncology. This study aimed to understand supportive care CPG implementation facilitators and barriers at pediatric oncology National Cancer Institute (NCI) Community Oncology Research Program (NCORP) institutions. It is one of three sub-studies within the Children’s Oncology Group (COG) study ACCL15N1CD.Methods: Healthcare professionals at 26 pediatric, COG-member, NCORP institutions were invited to participate in face-to-face focus groups. Serial focus groups were held until saturation of ideas was reached. CPG implementation facilitators and barriers were solicited using nominal group technique (NGT) and implementation of specific supportive care CPG recommendations was discussed. Notes from each focus group were analyzed using a directed content analysis. The top five themes arising from analysis of NGT items were identified, first from each focus group and then across all focus groups.Results: Saturation of ideas was reached after seven focus groups involving 35 participants from 18 institutions. The top five facilitators of CPG implementation identified across all focus groups were: organizational factors, individual factors, user needs and values, system factors and implementation strategies. The top five barriers of CPG implementation identified were: organizational factors, individual factors, system factors, user needs and values, and professional. Conclusions: Healthcare professionals at pediatric NCORP institutions believe that organizational factors are the most important determinants of supportive care CPG implementation. They believe that CPG-consistent supportive care is most likely to be delivered in organizations that prioritize evidence-based care, provide structure and resources to implement CPGs and eliminate implementation barriers.Trial registration: ClinicalTrials.gov Identifier: NCT02847130.

Abstract
Background: Evidence-based task-strengthening strategies for hypertension (HTN) control (TASSH) are not readily available for patients living with HIV in sub-Saharan Africa where the dual burden of HTN and HIV remains high. We are conducting a cluster randomized controlled trial comparing the effectiveness of practice facilitation versus a self-directed control (i.e., receipt of TASSH with no practice facilitation) in reducing blood pressure and increasing the adoption of task-strengthening strategies for HTN control within HIV clinics in Nigeria. Prior to implementing the trial, we conducted formative research to identify factors that may influence the integration of TASSH within HIV clinics in Nigeria.Methods: This study was conducted with purposively selected healthcare providers at 29 HIV clinics, followed by a one-day stakeholder meeting with 19 representatives of HIV clinics. We collected quantitative practice assessment data using two instruments: a) an adapted Service Availability and Readiness Assessment (SARA) tool to assess the capacity of the clinic to manage NCDs and b) Implementation Climate Scale to assess the degree to which there is a strategic organizational climate supportive of the evidence-based practice implementation. The quantitative data were analyzed using descriptive statistics and measures of scale reliability. We also used the Consolidated Framework for Implementation Research (CFIR), to thematically analyze qualitative data generated and relevant to the aims of this study.Results:Across the 29 clinics surveyed, the focus on TASSH (mean=1.77 (SD=0.59)) and educational support (mean=1.32 (SD=0.68)) subscales demonstrated the highest mean score, with good–excellent internal consistency reliability (Cronbach's alphas ranging from 0.84 to 0.96). Within the five CFIR domains explored, the major facilitators of the intervention included relative advantage of TASSH compared to current practice, compatibility with clinic organizational structures, support of patients' needs, and intervention alignment with national guidelines. Barriers included perceived complexity of TASSH, weak referral network and patient tracking mechanism within the clinics, and limited resources and diagnostic equipment for HTN.Conclusion:Optimizing healthcare workers' implementation of evidence-based TASSH within HIV clinics requires attention to both the implementation climate and contextual factors likely to influence adoption and long-term sustainability. These findings have implications for the development of effective practice facilitation strategies to further improve the delivery and integration of TASSH within HIV clinics in Nigeria.
Age-related hypertrophy of adenoid and tonsil with its effects on craniofacial morphology
Authors: Huang Xin , Gong Xu , Gao Xuemei 
Published: March 2021

Abstract
The present retrospective cross-sectional study was to compare craniofacial patterns resulted from different locations of upper airway obstruction. The study was conducted among 466 consecutive orthodontic patients who were divided into four groups: adenoid hypertrophy group (AG: 70 girls and 56 boys, 11.73±2.51 years), tonsillar hypertrophy group (TG: 38 girls and 21 boys, 12.47±2.72 years), adenotonsillar hypertrophy group (ATG: 36 girls and 33 boys, 11.07±3.35 years) and control group (CG: 151 girls and 61 boys, 12.92±2.34 years). Standard cephalometric examinations were used to compare the craniofacial differences between groups. The result indicated that adenoids and tonsils reached peak at around 6 years of age, after which the tonsils decreased more remarkably than the adenoids. Compared with CG, the proportions of skeletal class II in AG (43.7%) and ATG (44.9%) were significantly increased and the proportion of skeletal class III in TG (32.2%) was significantly increased. In age- and sex-adjusted linear regression models regarding CG as a benchmark, AG and ATG were positively correlated with ANB, MP/SN and FH/SGn but negatively correlated with SNB. In contrast, TG was positively correlated with SNA and SNB. Conclusion: Adenoid hypertrophy tended to lead to mandibular retrusion and high mandibular plane angle. In contrast, tonsillar hypertrophy showed a trend in mandibular protrusion. However, children with adenotonsillar hypertrophy did not show a mean facial pattern of the above two but were rather similar to those with isolated adenoid hypertrophy. It seemed that adenoid hypertrophy lasted longer and played a greater role.

Published: March 2021

Abstract
Many recent studies have demonstrated that morphological changes are one of the key signs of Meibomian gland disease (MGD) . These changes can be seen even before symptom onset, potentially underestimating the prevalence of MGD; however, Until now, there is no conclusive information about the impact of MG morphology in tear film physiology and disease. This study aimed to investigate the prevalence of anatomical and morphological MG alterations between patients with evapo-rative DED and healthy controls. Retrospective chart review of Seventy-five patients with evaporative dry eye and healthy individuals who had dry eye assesments included Ocular Surface Disease Index questionnaire, Meibum quality, meibum expressibility, lid margin abnormality, ocular staining, non-invasive tear film break-up time, and Meibography. We did not find significant differences in MG alterations in the upper lid between healthy and dry-eye subjects. Patients with evaporative dry eye presented MG alterations in the lower lid more frequently than healthy subjects (54.8 vs 30.3%; p=0.03). The presence of shortened glands was the only MG alteration that was more prevalent in the lower lid in dry-eye patients than in healthy subjects (p <0.05). Subjects with evaporative dry eye presented more alterations in the lower lid than healthy subjects.

Abstract
Background: This study aimed to identify the risk factors and predictors of neurologic outcomes and mortality for children with physical abuse and unintentional injury admitted to intensive care unit (ICU).Methods: We retrospectively evaluated the data for children with maltreatments admitted to the pediatric, neurosurgery and trauma ICUs between 2001 and 2019. Clinical factors were analyzed and compared between the physical abuse and the unintentional injury groups, including age, gender, season of admission, identifying settings, injury severity score, etiologies, length of ICU stay, neurologic outcomes, and mortality. Neurologic assessments were conducted with the Pediatric Cerebral Performance Category scale.Results: A total of 2,481 forensic children were collected, and there were 480 victims (19.3%) admitted to the ICus, including 156 physical abused and 324 unintentional injured. The significant difference between the two groups included age, histories of prematurity, clinical outcomes, head injury, neurosurgical interventions, clinical manifestations, brain computed tomography findings, and laboratory findings (all p<0.05). Traumatic brain injury (TBI) accounted for the majority of ICU patients. Abusive head trauma (AHT) was 87.1% in the abused group. In the abused group, only 46 (29.4%) cases achieved a favorable neurologic outcome. While268 (82.7%) achieved a favorable neurologic outcome in the unintentional injured group, Shock within 24 hours and spontaneous hypothermia (body temperature <35°C) presented the strong risk factors for poor neurologic outcomes and mortality in both group. Post-traumatic seizure was also associated with poor neurologic outcomes in both groups. Conclusions: In children with physical abuse and unintentional injuries on ICU admission, initial presentation with shock and spontaneous hypothermia may serve as the powerful predictors for mortality; and shock and convulsion may serve as the powerful predictors for poor neurologic outcomes. In addition, retinal hemorrhage could be a risk factor for poor neurologic outcomes in critical victims with physical abuse, and spontaneous hypothermia could be a risk factor for poor neurologic outcomes in unintentional injuries.
Visualizing the cultural landscape gene of traditional settlements in China: a semiotic perspective

Published: March 2021

Abstract
China has a deep traditional culture and a very long history, and is very rich in traditional settlements (designated as “Famous Historic-Cultural Villages/Towns”, “China Traditional Villages” by China Government). To help people develop the traditional settlements to achieve the great goal of Chinese National Rejuvenation, Chinese scholar put forward the Cultural Landscape Gene Theory of Traditional Settlements (CLGTS) in 2003. Since then, CLGTS has been employed to solve the issues of Chinese traditional settlements, such as the identification and regionalization of cultural genes in traditional settlements, and the understanding of architectural features. Although CLGTS has made great strides in many fields, there is still a lack of scientific findings in exploring the symbol mechanism from a perspective of semiotics. To explore this, we first examine the core features of CLGTS through a dialectic perspective. We analyze two features of CLGTS in depth. First, CLGTS is the dialectic combination of macro settlement image and micro cultural factors of traditional settlements, material appearance and inherent traditional cultural implications, overall features and local self-renewal mechanisms, qualitative and quantitative methods, superiority of cultural factors and rich cultural connotation. Second, CLGTS is famous for its nonlinearity, self-organization, and self-iteration due to various spatial shape and complex structures. Based on the above, we present the concept of a CLGTS Symbolization Method. Then, we further elaborate the key features, classification methods, and corresponding representation methods of CLGTS symbols. Finally, by using Visual C#.net program language, we develop a prototype system of the Traditional Landscape Genetic Symbol Database (TLGSD) to create and manage CLGTS symbols. Test results show that TLGSD can meet the needs of constructing a CLGTS symbol database for a given region. This study is of great significance to explore and contribute to the CLGTS Symbolization Method.
