Background: Persistent diarrhea is a known cause of mortality, morbidity, and malnutrition in developing countries. With recent improvement of rehydration therapy death due to acute diarrhea has been reduced. Though persistent diarrhea accounts for 2-20% of total diarrhea cases, it accounts for 23-62% of all diarrhea related deaths. Objective: The study was done to identify the risk factors associated with persistent diarrhea in children below 5 years of age.
Methods: This prospective observational study was conducted in the department of Pediatric Gastroenterology, Hepatology and Nutrition of Dhaka Shishu hospital from July 2019 to June 2020. It included 50 children with persistent diarrhea age between 1 month to <5 years. Detailed history, examination and appropriate investigations were done for all children. Crude odd ratio was calculated for each risk factor by univariate analysis and adjusted odds ratio was calculated by multivariate logistic regression.
Results: Most of the children (52%) were under the age of 6 months to 1 year. Male (84%) were more affected than female (16%). Acute malnutrition was observed in 44% cases; among them severe acute malnutrition was in 40% cases. Unsafe drinking water, severe acute malnutrition, diarrhea within past 2 months, bottle feeding, persistent of dehydration more than 24 hours, feeding of cow’s milk, lack of exclusive breast feeding, prior antibiotic used, UTI, LRTI were statistically significant risk factors by univariate analysis. Unsafe drinking water (OR-1.6; 95% CI- 0.27- 2.78), severe acute malnutrition (OR-1.92; 95% CI-0.64 - 5.72), Feeding of cow’s milk (OR-3.90; 95% CI- 1.21- 12.49), lack of exclusive breastfeeding (OR-5.77; 95% CI- 1.44- 23.10), irrational use of antibiotics (OR-3.37; 95% CI- 1.01- 11.38), LRTI (OR-1.16; 95% CI- 0.49- 1.53) were found to be independent risk factors by multivariate logistic regression analysis.
Conclusions: The results of this study concluded that use of unsafe drinking water, severe acute malnutrition, feeding of cow’s milk, lack of exclusive breastfeeding, irrational use of antibiotics are significant risk factors for the incidence of diarrhea in the present study population.

High internal phase emulsion (HIPE) templating is a well-established method for the generation of polymeric materials with high porosity (&gt;74%) and degree of interconnectivity. The porosity and pore size can be altered by adjusting parameters during emulsification, which affects the properties of the resulting porous structure. However, there remain challenges for the fabrication of polyHIPEs, including typically small pore sizes (∼20–50 μm) and the use of surfactants, which can limit their use in biological applications. Here, we present the use of gelatin, a natural polymer, during the formation of polyHIPE structures, through the use of two biodegradable polymers, polycaprolactone-methacrylate (PCL-M) and polyglycerol sebacate-methacrylate (PGS-M). When gelatin is used as the internal phase, it is capable of stabilising emulsions without the need for an additional surfactant. Furthermore, by changing the concentration of gelatin within the internal phase, the pore size of the resulting polyHIPE can be tuned. 5% gelatin solution resulted in the largest mean pore size, increasing from 53 μm to 80 μm and 28 μm to 94 µm for PCL-M and PGS-M respectively. In addition, the inclusion of gelatin further increased the mechanical properties of the polyHIPEs and increased the period an emulsion could be stored before polymerisation. Our results demonstrate the potential to use gelatin for the fabrication of surfactant-free polyHIPEs with macroporous structures, with potential applications in tissue engineering, environmental and agricultural industries.

Authors: Badacho Abebe Sorsa , Mahomed Ozayr Haroon 
Published: August 2023

BackgroundAccess to antiretroviral therapy (ART) allows people living with HIV (PLWH) to live longer. Consequently, non communicable diseases (NCD) have emerged as the main drivers of ill health, disability, and premature death. This study assessed the magnitude of hypertension and diabetes and risk factors among PLWH receiving ART in Ethiopia.MethodsA cross-sectional study was conducted using an analytical component. Data were collected through face-to-face interviews, physical measurements, and chart reviews of the 520 adults. Associations between the demographic and clinical attributes of hypertension and diabetes were assessed using logistic regression models.ResultsPrevalence of hypertension was (18.5%) (95% CI: 15.2%–21.7%), and diabetes was (6.9%) (95% CI: 4.8%–9.2%). More than two-thirds (70.8%) and 61% were newly diagnosed with hypertension and diabetes, respectively. Age &gt; = 45 years [adjusted odds ratio (AOR) = 2.47], alcohol consumption (AOR = 4.51), Insufficient physical activity (AOR = 3.7), BMI ≥25 (AOR = 3.95), family history of hypertension (AOR = 7.1), and diabetes (AOR = 4.95) were associated with hypertension. Age ≥45 years [adjusted odds ratio (AOR) = 2.47], BMI ≥25 (AOR = 1.91), Central obesity (AOR = 3.27), detectable viral load (AOR = 4.2), hypertension (AOR = 4.95) and duration of ART &gt;10 years (AOR = 3.12) were associated with diabetes.ConclusionsA combination of modifiable and nonmodifiable factors increased the risk of hypertension and diabetes. Primary prevention strategies, regular screening for hypertension and diabetes and integration with HIV care in primary health care are the recommended intervention measures.

Published: August 2023

BackgroundInformation is scarce regarding the clinical implications of aortic valve replacement (AVR) for patients suffering from moderate mixed aortic valve disease (MAVD), characterized by a combination of moderate aortic stenosis (AS) and regurgitation (AR). The objective of this retrospective study was to explore the clinical effects of AVR in individuals with moderate MAVD.MethodsWe examined the clinical data from patients with moderate MAVD and preserved left ventricular ejection fraction, who had undergone echocardiography in the period spanning from 2010 to 2018. Moderate AS was defined as aortic valve area index of 0.60–0.85 cm2/m2 and peak velocity of 3.0–4.0 m/s. Moderate AR was defined as a vena contracta width of 3.0–6.0 mm. The primary endpoint was a composite of all-cause death and heart failure hospitalization.ResultsAmong 88 patients (mean age, 74.4 ± 6.8 years; 48.9%, men), 44 (50.0%) required AVR during a median follow-up period of 3.3 years (interquartile range, 0.5–4.9). Mean values of specific aortic valve variables are as follows: aortic valve area index, 0.64 ± 0.04 cm2/m2; peak velocity, 3.40 ± 0.30 m/s; and vena contracta width, 4.1 ± 0.7 mm. The primary endpoint occurred in 32 (36.4%) patients during a median follow-up duration of 5.3 years (interquartile range, 3.2–8.0). Multivariable analysis revealed that AVR was significantly associated with the endpoint (hazard ratio, 0.248; 95% confidence interval, 0.107–0.579; p = 0.001) after adjusting for age, B-type natriuretic peptide, and the Charlson comorbidity index. Patients who underwent AVR during follow-up had significantly lower incidence rates of the endpoint than those managed with medical treatment (10.2% vs. 44.1% at 5 years; p &lt; 0.001).ConclusionsApproximately half of the patients diagnosed with moderate MAVD eventually necessitated AVR throughout the period of observation, leading to positive clinical results. Vigilant tracking of these patients and watchful monitoring for signs requiring AVR during this time frame are essential.
Algorithm for planning shelters in oil and gas energy resource-based cities based on artificial intelligence resilient city model
Authors: Liang Jing , Ge Ming 
Published: August 2023

Cities based on oil and gas energy resources are crucial to energy production and economic development, but they also face various disasters and security risks. To ensure the safety and well-being of urban residents during disaster events, the planning of urban shelters is crucial. In this paper, comprehensively considering multiple factors such as disaster risk, population distribution, and convenient transportation, the artificial bee colony algorithm is used to optimize the site selection and capacity planning of shelters. By comprehensively evaluating the disaster resistance capacity of urban refuges, the response speed of residents and other related indicators, the planning algorithm of refuges is continuously optimized to better meet the needs of oil and gas energy resource-based cities. The results of the study showed that the average overall disaster resilience of AI-based urban shelters reached 0.64. When the distance to the shelter was 4 km, the average response speed of residents reached 10.22 min, and other indicators also improved. The research shows that the oil and gas energy urban refuge planning algorithm based on the artificial intelligence elastic city model provides an innovative approach for urban planners and disaster managers. Further research and practice will help promote the application of this algorithm in real cities, improving the resilience and disaster resistance of cities and the safety and security level of residents.

IntroductionAs a vital component of the ecosystem of the Qinghai-Tibet Plateau, alpine wetlands coexist with their vulnerability, sensitivity, and abundant biodiversity, propelling the material cycle and energy flux of the entire plateau ecosystem. In recent decades, climate change and human activities have significantly altered the regional landscape. Monitoring and assessing changes in the alpine wetlands on the Qinghai-Tibet Plateau requires the efficient and accurate collection of long-term information.MethodsHere, we interpreted the remote sensing data of the first meander of the Yellow River of alpine wetlands from 1990 to 2020 based on Google Earth Engine (GEE) platform, using geographic information system (GIS) and landscape pattern index to analyze the spatial and temporal evolution of wetland landscape patterns, and the primary drivers of changes in wetland area were explored by GeoDetector.ResultsOur result showed that most wetland areas were found in regions with gradients less than 12° and elevations between 3315 and 3600 m. From 1990 to 2010, the area of alpine wetland in the study area decreased by 25.43%. During the period between 2010 and 2020 to the 1990s, the wetland area decreased by 322.9 km2. Conversion to and from grassland was the primary form of wetland transfer out and in, respectively. The overall migration of the wetland centroid in the study area was to the southwest between 1990 and 2010 and to the north between 2010 and 2020. The geometry of the wetland landscape was relatively simple, the landscape was relatively intact, and patches retained a high level of agglomeration and connectivity. However, their level of agglomeration and connectivity was disrupted. A quantitative analysis of the factor detector in GeoDetector revealed that the DEM, slope, and evaporation were the most important driving factors influencing the change of wetland area, with socioeconomic development also influencing changes in the wetland area to a lesser extent.DiscussionUsing interaction detectors, it was discovered that the interaction of various driving factors could better explain the long-term variations in wetland areas, with a greater degree of explanation than that of each driving factor alone.

Published: August 2023

Background: To study the genetic basis of the impact of genotypes and morpho-physio-biochemical traits under different organic and inorganic fertilizer doses on the shelf life attribute of tomatoes, field experiments were conducted in randomized block designs during the rabi seasons of 2018–2019 and 2019–2020. The experiment comprised three diverse nutrient environments [T1—organic; T2—inorganic; T3—control (without any fertilizers)] and five tomato genotypes with variable growth habits, specifically Angoorlata (Indeterminate), Avinash-3 (semi-determinate), Swaraksha (semi-determinate), Pusa Sheetal (semi-determinate), and Pusa Rohini (determinate).Results: The different tomato genotypes behaved apparently differently from each other in terms of shelf life. All the genotypes had maximum shelf life when grown in organic environments. However, the Pusa Sheetal had a maximum shelf life of 8.35 days when grown in an organic environment and showed an increase of 12% over the control. The genotype Pusa Sheetal, organic environment and biochemical trait Anthocyanin provides a promise as potential contributor to improve the keeping quality of tomatoes.Conclusion: The genotype Pusa Sheetal a novel source for shelf life, organic environment, and anthocyanin have shown promises for extended shelf life in tomatoes. Thus, the identified trait and genotype can be utilized in tomato improvement programs. Furthermore, this identified trait can also be targeted for its quantitative enhancement in order to increase tomato shelf life through a genome editing approach. A generalized genome editing mechanism is consequently suggested.
