Frailty Status, Not Just Age, is Associated With Postoperative Opioid Consumption: A Retrospective, Population-based Analysis

Objective: To assess the relationship between postoperative opioid consumption and frailty status. Background: Physiologic reserve can be assessed through both chronologic age as well as measures of frailty. Although prior studies suggest that older individuals may require less opioid following surgery, chronologic age, and frailty do not always align, and little is known regarding postoperative opioid consumption patterns by frailty. Methods: We conducted a retrospective analysis of opioid-naïve adult patients undergoing common general, vascular, and gynecologic procedures across a statewide quality improvement program from November 6, 2017 to February 28, 2021. Our primary outcome was postoperative patient-reported opioid consumption within 30 days of surgery in oral morphine equivalents (OME). Our primary exposure was frailty status defined by the modified frailty index (mFi-5) criteria. Other covariates included patient demographic and clinical attributes, procedural factors, discharge opioid prescription size, and postoperative complications. Linear regression was performed to assess the association of frailty status and opioid consumption, stratified by age. Results: In this cohort of 34,854 patients, 10,596 had an mFi-5 score of ≤1 and 3,635 had a score of >1. A score of >1 was associated with increased patient-reported opioid consumption (OMEs 3.3 greater; 95% CI = 1.5–5.1). This held true for individuals over 65 (OMEs 2.7 greater; 95% CI = 0.2–5.1). Frailty status, regardless of score, was negatively associated with an opioid prescription at discharge. Conclusions: Frailty status is associated with increased opioid consumption after common operations. Future prescribing guidelines and outcomes analyses should consider this marker when reviewing opioid consumption data and related adverse outcomes.

Has the Development of Broadband Infrastructure Improved Household Energy Consumption in Rural China?

Digital infrastructure plays a crucial role in shaping household energy consumption behaviors, especially in the context of achieving carbon peaking and carbon neutrality goals in China. In this study, we explored the impact of broadband infrastructure on household energy consumption and clean fuel choices, using data from the China Health and Retirement Longitudinal Study (CHARLS). In a difference-in-differences (DID) framework, our findings indicate that the promotion of broadband infrastructure significantly increases rural household energy consumption and facilitates a transition to cleaner energy sources. Notably, households with better socioeconomic status, particularly those with higher education and income levels, benefit more from enhanced broadband internet access. Mechanism analysis reveals that the “Broadband China” policy can positively influence household consumption through several potential channels: fostering technological innovation, enhancing energy efficiency in cities, and improving overall environmental awareness. These findings contribute to our understanding of the role of broadband infrastructure in shaping household energy consumption patterns and have important implications for policymakers, particularly in the context of sustainable development and energy transition efforts.

Exploring the Effects of Whole Food-Based Dragon Fruit on Metabolic Disorders in High-Fat Diet-Induced Mice.

Metabolic syndrome (MetS) significantly contributes to premature mortality, with obesity being a major risk factor. Dragon fruit, cultivated globally, exhibits bioactivity in preventing obesity-related diseases. Traditional studies using organic solvents for extraction do not align with actual consumption patterns. This study evaluates whole red dragon fruit's effectiveness in ameliorating metabolic disorders using a high-fat diet-induced obesity model in mice for 20 weeks. The experimental groups include the supernatant (RS), precipitate (RP), and pomace (PO) of red dragon fruit juice, compared to the supernatant of white dragon fruit juice (WS). The study finds that dragon fruit extracts reduced adipose tissue weight, body fat percentage, pro-inflammatory cytokines, and improved blood lipid profiles. RP is the most effective, reducing body weight by 4.33g, improving lipid metabolism and glucose homeostasis, and altering gut microbiota to enhance beneficial bacteria and short-chain fatty acids. RP's efficacy in preventing MetS and obesity is attributed to its bioactive components. These findings advocate for using whole fruits in developing functional products, amplifying the agricultural economic value of red dragon fruit.

Analysis of differences in fossil fuel consumption in the world based on the fractal time series and complex network

Fossil fuels remain indispensable energy resources despite their non-renewable nature. Understanding the patterns of global fossil fuel consumption is essential for energy security and policy-making. This study employs complex network theory and fractal time series analysis to explore the underlying dynamics and patterns of fossil fuel consumption globally, with a focus on coal, oil, and gas consumption.The study applies the Hurst index to raw fossil fuel consumption data to identify fractal characteristics. Additionally, the visibility graph method is used to convert time series data into complex networks, allowing further analysis of consumption patterns. The study examines fossil fuel consumption in 38 countries to assess global trends and differences. The analysis reveals that global fossil fuel consumption follows a fractal time series pattern, with Hurst index values exceeding 0.9, indicating long-term memory characteristics. The application of the visibility graph method demonstrates variations in the Hurst index of degree distribution, enabling the differentiation of consumption patterns across regions. The method also uncovers distinct features of coal, oil, and gas consumption when viewed from a network perspective. The findings suggest that fossil fuel consumption has predictable long-term patterns, which are crucial for assessing future energy demands. The study highlights the importance of legislative measures to safeguard fossil fuel resources, especially for countries like China, where energy security and international competitiveness are paramount. Understanding these consumption patterns could guide future energy policies aimed at managing non-renewable resources more effectively.

Emerging Contaminants Related to Brazilian Aquaculture

ABSTRACTResearch efforts around the world have focused on identifying the occurrence of emerging contaminants in aquaculture areas. In the Brazilian context, studies have aimed to identify emerging contaminants in water used for this activity. This systematic review covered studies published without a specific time frame with the following criteria: research conducted in aquaculture areas or with species and cultured water in Brazil and analysis of emerging contaminants. Out of the 42 studies identified, 132 emerging contaminants were observed. The Southeast and South regions accounted for most of these studies, with limited research conducted in the North and Northeast regions. Tilapia was the most studied species, followed by mollusks. In toxicity tests, animals showed several effects, such as decreased oxygen consumption and swimming patterns, histopathological changes, inhibition of sperm production, cardiac edema, spinal deformity, and antimicrobial resistance. In conclusion, advancements in research on emerging contaminants in Brazilian aquaculture are needed as the number of existing studies is lower compared to global numbers. Few studies have focused on analyzing cultivation sites to identify the contaminants present and their sources. Also noteworthy is the scarcity of work in the Northern region of Brazil and on native species. Characterizing these environments in terms of the types of contaminants and main sources of contamination is essential to finding ways to mitigate ecological and human health risks, as well as developing specific legislation for these contaminants because they are currently not part of routine monitoring programs and are therefore not regulated, especially in aquaculture environments.

Assessment of Water Consumption Behavior in Single Households Using Smart Water Meters

Smart meters monitor hourly water consumption patterns while reducing the cost and inconvenience of traditional meters. This study comprehensively analyzes 1871 households that previously used traditional meters from the distribution point to the distribution area. All the households were equipped with smart meters and the data collected were used for analysis. On the basis of the total estimated water consumption, 227 households were classified as single households. These households were further classified into single-worker and -nonworker households. This study analyzed smart meter data to evaluate the timings and amounts of water consumption peaks. The results indicate that worker households peaked at 8:00, with 29 L/h of consumption on weekdays, and peaked again on evenings at 20:00–21:00, averaging 32 L/h. For nonworker households, the peak occurred at 9:00, with 20 L/h, with no major changes in the afternoon, and a second peak occurred at 19:00–20:00 in evening, with an average of 19 L/h. Moreover, worker households peaked at 8:00 and 20:00 on weekdays, and at 9:00 and 19:00 on weekends. It was revealed that worker households consume 10% more on weekends than on weekdays, and 262% more from 13:00 to 16:00. These findings may assist in water supply planning by supporting distribution schedules on the basis of peak household consumption, leading to more helpful resource management.

Adoption of e-wallets: trust and perceived risk in Generation Z in Colombia

Purpose This study aims to explore the development of trust in relation to security and privacy concerns, as well as the influence of perceived risk on the intention to use e-wallets. The research focused on the Colombian context because of its characterization as an underdeveloped financial system that has experienced considerable security and privacy violations in recent years. Additionally, this geographical area is relatively under-researched, and the target demographic for this investigation was Generation Z, given their pivotal role in driving the adoption of e-wallets. Design/methodology/approach Based on measurement scales that had already been tested in the academic literature on mobile payment systems, a questionnaire was developed and distributed electronically. A total of 424 responses were obtained from young Colombians. Structural equation modeling (SEM), specifically the PLS-SEM method, was used to process the data to study the explanatory and predictive power of the proposed model. Findings The findings revealed that security and privacy have a positive and significant effect on perceived trust, and that this at the same time has a positive and significant effect on attitude, perceived usefulness, perceived ease and intention to use, as well as a significant but negative effect on perceived risk. On the other hand, perceived risk showed an inverse, but not significant, relationship with intention to use. Originality/value This research explored the adoption of e-wallets by young people in Colombia, which has been widely claimed in the academic literature. In a turbulent context with a high distrust of financial institutions, as well as a change in digital money consumption patterns, it is critical to understand the factors that contribute to the adoption of mobile payment services. The findings, in addition to contributing to the academic debate, have important implications for e-wallet providers, as they offer information that allows designing strategies to attract and keep current and potential users. At the same time, the recommendations by the authors allow the design of tools, especially related to security and privacy, to improve their trust and build loyalty, thus contributing to the consolidation and development of the mobile payment system.

“A Review Of The Study Of Estimation Of The Concentration Of Particulate Matter Over Chhatrapati Sambhajinager (M.S) City Using Remote Sensing”

India’s ongoing population explosion has imposed a great strain on the country’s environment. This rapid growth in population along with urbanization and industrialization has placed lot of pressure on India’s infrastructure and natural sources. Forests destruction, soil erosion, water pollution and lowering of the level’s quality continue to hinder economic development in under developed and rural region of India. The rapid urbanization and subsequently industrialization in India leads degrading environmental condition in metro cities in India. Chhatrapati Sambhajinager cannot be an exception Chhatrapati Sambhajinager is one of the most affected cities where air particulate matters (PM) have been registered at the levels more than 10 times our country’s legal limit (Ninawe et-al 2010). Despite of introducing legal policy measures in India air pollution remained major concern. In many urban areas including Chhatrapati Sambhajinager, there is high level of pollution. This cause increase in the levels of air pollution including deforestation that is causing human health hazards. In India aggravation of air pollution is owing to the rapid and growth in the size of cities. The movement of people from one place to other helped to Increase in consumption pattern, unplanned urban and industrial development is the main causes of air pollution in big cities of India that resulted the worst. (Chitale et-al 2010). In India, the most severe problem of environment comes in varied forms including vehicular emissions and unsaturated industrial smoke. This has resulted in bringing about adverse effect on population and cities are unable to implement pertinent pollution control mechanism. High concentration of pollution in India is not due to absence of a sound environment legal regime, but is due to lack of environmental enforcement at the local level. Regulatory reforms aimed to improving the air pollution problem in most of the metro cities. To my knowledge this might be the first attempt in Maharashtra, to produce high-resolution of particulate matter and gaseous NO2 and SO2 pollution surface, making use of remote sensing data (Kourase et-al 2010). The outcome of this research work will be made available to help expose health research in this polluted and densely populated region

POLICY DRIVERS OF CHINA'S INTEGRATED ENERGY SERVICES: A CURRENT STATUS REVIEW

Conventional energy production and consumption patterns seriously restrict global sustainable development. In the energy transformation process, integrated energy services play a key role in integrating clean energy and renewing energy consumption patterns. The European Union, the United States, and Japan are leading in developing policy frameworks and integrating integrated energy services. This paper compares and analyzes how the European Union, the United States, Japan, and China respond to the challenges of energy transformation through different energy policy systems. The energy policy systems of the European Union, the United States, and Japan are discussed for reference by China. The review reveals that (1) assigning tasks based on the energy transformation strength of each region is conducive to accelerating the speed of carbon emission reduction in each region; (2) continuous government support and targeted incentives are conducive to attracting market capital, thereby stimulating the advancement of energy technology; and (3) formulating energy efficiency standards for basic equipment can lay a good foundation for energy transformation.

Physical, socio-psychological, and behavioural determinants of household energy consumption in the UK

Determining which attitudes and behaviours predict household energy consumption can help accelerate the low-carbon energy transition. Conventional approaches in this domain are limited, often relying on survey methods that produce data on individuals’ motivations and self-reported activities without pairing these with actual energy consumption records, which are particularly hard to collect for large, nationally representative samples. This challenge precludes the development of empirical evidence on which attitudes and behaviours influence patterns of energy consumption, thus limiting the extent to which these can inform energy interventions or conservation programs. This study demonstrates a novel methodology for estimating energy consumption in the absence of actual energy records by using a large, publicly available data set of energy consumption in the UK. We develop a predictive model using the Smart Energy Research Laboratory (SERL) data portal (with records from nearly 13,000 UK households) and then use this model to predict energy consumption (both electric and gas) for a sample of 1,000 UK householders for which we separately collect over 200 variables relating to climate change attitudes and practices. Our approach uses a set of over 50 independent variables that are shared between the data sets, allowing us to train a model on the SERL data and use it to analyse the relationship between energy consumption and the opinions, motivations, and daily practices of survey respondents. Results show that electricity consumption is influenced by a broader range of factors compared to gas. Household energy use is best explained by physical dwelling characteristics, socio-demographic variables, and certain behavioural and attitudinal measures. Notably, pro-environmental attitudes, frugality, and conscientiousness correlate with lower energy use, while income and consumerism are linked to higher consumption. We discuss how these findings can inform efforts to decarbonise home energy use in the UK.

Evaluation of the prevalence and influencing factors on poly-pharmacy among elderly patients - A review

ABSTRACT The evaluation of adverse effects caused by poly-pharmacy (PHP) in patients, especially in the elderly group, is very important. The purpose of the present study was to evaluate the prevalence and factors affecting PHP in elderly patients. This study was conducted as a narrative review. Related articles were downloaded using reliable international databases and specialized mesh terms. Finally, the results of 29 articles were extracted based on the authors’ names, study location, sample size, and key results. The findings of the study showed that the prevalence of PHP in the elderly was higher after discharge from the hospital than during hospitalization. In addition, the prevalence of PHP in the elderly who lived in care centers was higher than in those who lived at home. Based on the findings, there was a relationship between the source of obtaining information about drugs and the pattern of PHP consumption. The findings of the present study showed that PHP leads to serious complications in the elderly. Based on the results of the study, it can be concluded that some variables such as age, sex, health level, financial status, place of residence, type of disease, number of simultaneous diseases, hospitalization, duration of hospitalization, level of awareness of the elderly and their caregivers, the care place of elderly, and the number of visits of the elderly to the physician can be effective in the prevalence of PHP. Strategies such as choosing treatment goals for each patient in preventing unnecessary drug use, identifying at-risk groups, and periodically monitoring the benefits and side effects of drugs can be effective in reducing drug complications caused by PHP in the elderly.

Assessing the impact of weathered polystyrene collected from the marine environment on oxidative stress responses in Zophobas morio larvae: A preliminary study

Foamed polystyrene (PS) is a prevalent material in consumer products and thus represents one of the largest constituents of marine litter. PS may interact with and be ingested by various organisms, including insects, which are starting to be used in biodegradation of plastic wastes. This study examines the physiological performances and the potential oxidative stress related to dietary environmental PS exposure of Z. morio larvae. Experimental groups were fed different diets: bran and oatmeal (control), weathered PS collected from the marine environment, and virgin PS. Over a 30-day feeding period, larvae growth, survival, and PS consumption were measured, together with antioxidant enzymatic activities and gene expression profiles. Results showed that PS ingestion supports larval growth similarly to bran, but the two PS-fed groups consumed a different amount of plastic, suggesting that weathered PS might affect the patterns of PS consumption by larvae. We denoted that PS consumption was associated with a decline in total antioxidant capacity, which showed the highest decrease in the environmental PS group. Marked increases in oxidative stress biomarkers such as superoxide dismutase (SOD) activity/mRNA levels and malondialdehyde content were also observed in the environmental PS-fed group, indicating an elevated oxidative stress response, probably due to pollutants adsorbed/absorbed on PS. Differently to SOD, catalase at both mRNA and enzyme activity levels was found to be significantly reduced by PS digestion, regardless of PS type. The mRNA levels of glutathione s-transferase (GST) were significantly higher in the environmental PS-fed larvae compared to the virgin PS-fed group. In addition, Principal Component Analysis clearly distinguished between larvae fed different PS types, highlighting the enhanced oxidative stress caused by the ingestion of PS collected from marine environments. These results support the potential of insects in plastic biodegradation processes but also demonstrate the health hazards of using environmental PS as principal dietary component in Z. morio larvae, thus questioning their use in downstream productions.

Health literacy and tobacco cessation among hypertensive individuals: A mixed method study

BACKGROUND: Hypertension and tobacco addiction are two major public health challenges in India that frequently coexist. About 30% of Indian adults have hypertension, while over one-fourth use some form of tobacco. So, the present study aimed to determine the prevalence and patterns of tobacco consumption and identify associated socio-demographic factors among hypertensive patients in urban India and also further explored patient perspectives regarding tobacco use through qualitative interviews. MATERIALS AND METHODS: This mixed-method study was conducted among 305 hypertensive adults recruited from an urban tertiary hospital using interviewer-administered questionnaires. Additionally, 15 tobacco-consuming patients were purposively sampled for in-depth interviews regarding perceptions and behaviors related to tobacco. Descriptive statistics and multi-variable logistic regression models were applied for quantitative analysis and thematic analysis for qualitative data. RESULTS: The prevalence of ever tobacco use among hypertensive patients was 21%. Smokeless tobacco was the predominant form used. Male gender, urban locality, illiteracy, and lack of knowledge about tobacco hazards had a higher likelihood of tobacco consumption. Qualitative interviews provided complementary insights into triggers like peer influences and stress, barriers to quitting including withdrawal effects and system gaps, and participant perspectives on facilitating cessation. CONCLUSION: Tobacco consumption among hypertensives is higher than national averages. Tailored educational, motivational, and policy-level interventions addressing gaps in knowledge, risk perceptions, addiction behaviors, and cessation support systems can enable the promotion of tobacco abstinence and hypertension control in this vulnerable sub-group. The multi-method data provide actionable inputs for planning targeted control and prevention strategies addressing this dual burden.

Gold removal from e-waste using high-intensity focused ultrasound

The demand for rare and precious metals (RPMs), e.g. gold, is increasing, as these are used in the ever-increasing amount of electronics needed for technological development and digitalization. Due to their rarity, virgin mining of RPMs is becoming more difficult and expensive. At the same time, over 62Mt of e-waste is created globally each year. The high concentration of gold and other RPMs in e-waste makes it an excellent source for recycling. Unfortunately, current recycling methods need to separate the different metals and the current pyrometallurgical and hydrometallurgical processes also create toxic pollutants, large amounts of wastewater and require highly corrosive substances. Here we present a new method for gold removal for the purpose of recycling, using only water and high-intensity focused ultrasound to induce material erosion through cavitation. An 11.8 MHz ultrasonic transducer is used to first image the sample to locate gold-coated pads on discarded printed circuit boards (PCBs) and subsequently to remove only the gold layer. We demonstrate that the gold removal can be controlled by the number of transmitted ultrasonic bursts and that the energy efficiency is optimal when only minute amounts of the nickel layer beneath are also removed. Removing solely the gold layer also decreases the need for further processing steps. This greener gold removal method for e-waste is therefore well aligned with, and contributing to, the United Nations Sustainable Development Goal 12: Ensure sustainable consumption and production patterns.

Alternative Fine Aggregates to Natural River Sand for Manufactured Concrete Ensuring Circular Economy

To address SDG12 (ensure sustainable consumption and production patterns), and to provide technical evidence for alternative concrete constituents to traditional natural river sand, stone fine aggregate (SFA), brick fine aggregate (BFA), ladle-refined furnace slag aggregate (LFS), recycled brick fine aggregate (RBFA), and washed waste fine aggregate (WWF), ready-mix concrete plants were investigated. Concrete and mortar specimens were made with different variables, such as replacement volume of natural sand with different alternative fine aggregates, water-to-cement ratio (W/C), and sand-to-aggregate volume ratio (s/a). The concrete and mortar specimens were tested for workability, compressive strength, tensile strength, and Young’s modulus (for concrete) at 7, 28, and 90 days. The experimental results show that the compressive strength of concrete increases when natural sand is replaced with BFA, SFA, and LFS. The optimum replacement amounts are 30%, 30%, and 20% for BFA, SFA, and LFS, respectively. For RBFA, the compressive strength of concrete is increased even at 100% replacement of natural sand by RBFA. For WWF, the compressive strength of concrete increases up to a replacement of 20%. Utilizing these alternative fine aggregates can be utilized to ensure a circular economy in construction industries and reduce the consumption of around 30% of natural river sand.

CFD simulations of the transition between non-aerated and aerated conditions in uncovered unbaffled stirred tanks

The transition between non-aerated and aerated regimes in uncovered unbaffled stirred tanks (UUSTs) was investigated using computational fluid dynamics (CFD). The Volume of Fluid (VOF) method was employed to model the free surface dynamics under various operational conditions. The simulations were able to predict the peculiar experimentally observed behavior of UUSTs and revealed that at velocities below a critical threshold (N_<_Ncrit), the system remains non-aerated, while exceeding this threshold (N_≥_Ncrit) induces bubble ingestion, leading to significant changes in power consumption and flow patterns. The CFD simulations accurately predicted the behaviour of the Power Number (Np) as well as the vortex shape inside the tank both in subcritical and supercritical regimes and showed good agreement with original experimental data and correlations from the literature. Additionally, the modeling of the aerated regime successfully predicted the vortex shape, the bubble dispersion within the tank, and the cavities formed behind the blades.

Energy audit based identification of energy efficiency improvement opportunities for existing houses

Energy efficiency in the building has two dimensions; efficient use of energy resources and energy conservation. Energy-efficient houses play a critical role in energy conservation and achieving sustainable built environment goals. The energy efficiency of a house depends on its building envelope (design, orientation, and energy properties of construction material) and operational characteristics appliance efficiency, energy consumption patterns). Rather than merely ensuring new houses are energy-efficient, it is vital to energy retrofit existing houses. Energy audits can assist in evaluating the energy efficiency of existing houses and identify improvement measures. The main objectives of this study were to identify efficiency improvement opportunities through an energy audit of houses and apartments in Karachi. A detailed energy audit checklist was prepared using literature, standards, expert review, and code requirements. Data was collected through physical and owner-assisted virtual audits of 58 houses in six districts of Karachi. Architectural plans, information about doors, windows, air ducts, thermal images, historical data, and material properties were collected. Audit tools included; an anemometer and thermal imagining camera during physical audits. Android applications were used during owner-assisted audits. Data were analyzed for developing descriptive graphs, U and R-values, Pareto charts, and district-wise mapping of energy properties of the material. As a result, energy improvement opportunities were proposed. These are focused on building envelope aspects, including; window orientation, minimizing air infiltration, and using heatresistant paint. Improvement measures were confirmed through thermal imaging of selected buildings.
