Respiratory changes in children exposed to dust from mining waste in Brumadinho, Minas Gerais State, Brazil: Bruminha Project

This study aimed to investigate the occurrence of respiratory diseases in children exposed to dust from mining waste after the Brumadinho dam disaster, Minas Gerais State, Brazil. The study population included children aged 0-6 years, living in three communities exposed to mining waste dust (Córrego do Feijão, Parque da Cachoeira, and Tejuco) and one unexposed community (Aranha). Data were collected from July 19 to 30, 2021, using questionnaires that addressed sociodemographic information and a recall survey on signs, symptoms, and respiratory diseases. A total of 217 children were evaluated, 119 living in the exposed communities and 98 in the non-exposed community. The residents in the exposed communities reported an increase in the frequency of home cleaning (p = 0.04) and in vehicular traffic (p = 0.03). Among children aged four, a higher frequency of upper (p = 0.01) and lower (p = 0.01) airway disorders, as well as respiratory allergy (p = 0.05) was observed. The exposed group had 1.5 times more reports of respiratory allergy (75%; p = 0.02) compared to the non-exposed group (50.5%). Children living in communities exposed to waste dust were three times more likely (adjusted OR = 3.63; 95%CI: 1.37; 9.57) to have respiratory allergies than those not exposed. Two years and six months after the environmental disaster occurred, children living in the communities affected by waste from mining and remediation activities remained exposed to dust with harmful effects on respiratory health.

Household Use of Green Cleaning Products, Disinfecting Wipes, and Asthma Control Among Adults

BackgroundThe use of Household Disinfectants and Cleaning Products (HDCPs) may negatively impact asthma control, but studies remain scarce. Moreover, none considered green products or wipes, increasingly used during home cleaning. ObjectiveTo assess the associations between the use of HDCPs, including disinfecting wipes and green products, and asthma control based on data from the French web-based NutriNet-Santé cohort. MethodsUsing a standardized questionnaire (2018), we assessed asthma control (never asthma - reference, controlled: ACT≥20, uncontrolled: ACT<20) and the use of HDCPs, including two types of products (irritants and green products) and two application modes (sprays and disinfecting wipes). Cross-sectional associations of the frequency of weekly use of HDCPs at home with asthma control, adjusted for gender, age, smoking status, body mass index and educational level were assessed by multinomial logistic regressions. ResultsAnalyses were performed on 37,043 adults (mean age: 47 years, 75% women, 62% with a weekly use of at least one HDCP). Strong associations were observed between weekly use of HDCPs and uncontrolled asthma. In particular, an almost daily use (4-7 days a week) of irritants (OR=2.81[1.97-4.00]), green products (OR=2.40[1.70-3.39]), as well as sprays (OR=2.69[1.97-3.68]) and disinfecting wipes (OR=3.51[2.31-5.33]) was associated with uncontrolled asthma. When not co-used with irritants and sprays, associations remained statistically significant for both disinfecting wipes and green products. ConclusionWeekly use of HDCPs, including green ones or wipes, was associated with uncontrolled asthma and should be considered by health practitioners in order to improve asthma control.

Using Hyperlocal Delivery System to Accelerate Localised Business

Hyperlocal organizations provide purchasers with merchandise delivery and utility administrations. Merchandise delivery includes staple goods, food, prescriptions, and personal needs, while utility administrations include plumbing, home cleaning, yard care, electrical, and drainage. Each of these services and products is provided by an organization of individuals from businesses or neighborhoods. Hyperlocal administration stages enable eateries, lodging, discount food outlets, organic products or vegetables, fish, and meat, and other retailers to attract and manage customers effectively without worrying about shipment. Simple web connectivity and the proliferation of cell phones have significantly increased interest in hyperlocal administrations. Occupied way of life accelerates the growth of the online food and staples ordering market, which in turn accelerates the growth of hyperlocal services in the emerging online market.

Effectiveness of Fine Dust Environmental Education on Students’ Awareness and Attitudes in Korea and Australia Using AR Technology

This study evaluated the influence of fine dust environmental education on 90 elementary and middle school students, taking into account factors such as sex, place of residence, experience with environmental education, and experience with augmented reality (AR). The goal was to assess changes in students’ awareness and attitudes towards fine dust. Results showed that fine dust environmental education positively influenced students’ awareness of fine dust. Further analysis by factors revealed that the education was effective regardless of these factors. In addition to increasing awareness of the seriousness of fine dust, students’ attitudes also changed positively. The study conducted a statistical analysis of changes in 10 types of attitudes among the target students before and after our education. After the implementation of the education, students’ attitudes changed positively in all 10 types of attitudes, including checking the weather, restricting activities, personal hygiene, wearing masks, environmental education, separating garbage and cleaning, classroom silence, classroom ventilation, home cleaning, and home environment with statistical significance. These findings underscore the effectiveness and importance of combining fine-dust environmental education with AR technology and can inform the planning of educational programs aimed at improving students’ awareness and attitudes.

Socio-demographic factors and treated wastewater reuse in the MENA region: Insights and implications

Decision-makers in the Middle East and North Africa (MENA) region are looking for ways to recycle wastewater to meet the demand for water amidst scarcity. Reusing treated wastewater is crucial for managing water resources sustainably, particularly in water-stressed nations in arid regions of the world that rely on desalination and groundwater to meet their water needs. This study looks into how socio-demographic factors affect how the general public feels about utilizing wastewater for various purposes. A structured questionnaire was used to collect data from 1206 respondents throughout the MENA region, and descriptive and inferential statistics were used to analyze the results. The MENA region is found to recognize the environmental benefits of reuse, but prefers applications that have less direct human interaction such as flushing toilets, non-food industries, car washes, home cleaning, and firefighting. The public is open to reuse as long as it is approved by professionals such as medical experts, university professors and experts. Gender and wealth did not significantly influence the confidence to use treated wastewater for most reuse applications. Still, age and education level did not have a major impact. All respondents agreed to use treated wastewater for non-food business, car washing, home cleaning, and firefighting. Study findings provide insight into the attitudes and perceptions of individuals toward treated wastewater reuse, and can inform future efforts to promote the acceptance and implementation of these applications.

Metagenomics reveals novel microbial signatures of farm exposures in house dust.

Indoor home dust microbial communities, important contributors to human health, are shaped by environmental factors, including farm-related exposures. Advanced metagenomic whole genome shotgun sequencing (WGS) improves detection and characterization of microbiota in the indoor built-environment dust microbiome, compared to conventional 16S rRNA amplicon sequencing (16S). We hypothesized that the improved characterization of indoor dust microbial communities by WGS will enhance detection of exposure-outcome associations. The objective of this study was to identify novel associations of environmental exposures with the dust microbiome from the homes of 781 farmers and farm spouses enrolled in the Agricultural Lung Health Study. We examined various farm-related exposures, including living on a farm, crop versus animal production, and type of animal production, as well as non-farm exposures, including home cleanliness and indoor pets. We assessed the association of the exposures on within-sample alpha diversity and between-sample beta diversity, and the differential abundance of specific microbes by exposure. Results were compared to previous findings using 16S. We found most farm exposures were significantly positively associated with both alpha and beta diversity. Many microbes exhibited differential abundance related to farm exposures, mainly in the phyla Actinobacteria, Bacteroidetes, Firmicutes, and Proteobacteria. The identification of novel differential taxa associated with farming at the genera level, including Rhodococcus, Bifidobacterium, Corynebacterium, and Pseudomonas, was a benefit of WGS compared to 16S. Our findings indicate that characterization of dust microbiota, an important component of the indoor environment relevant to human health, is heavily influenced by sequencing techniques. WGS is a powerful tool to survey the microbial community that provides novel insights on the impact of environmental exposures on indoor dust microbiota. These findings can inform the design of future studies in environmental health.

Survival Strategies for Nigerian Youths

Honestly speaking, Nigeria is blessed with abundant natural, human and material resources yet her citizens are suffering tremendously especially the youths. This is caused by bad leadership cum lackadaisical attitudes orchestrated by greedy and disgruntled politicians. The conspicuous immediate effect is that the poor are getting poorer while the rich are getting richer on daily basis. It is also obvious that there are problems already on ground in the country ranging from social problems (poverty, unemployment, unequal opportunity, racism, crime, cultism, terrorism, human trafficking, employment discrimination and malnutrition), religious bigotry, economic quagmire, political to environmental problems. These existing problems have done more harm than good especially on the parts of our youths at present. Our youths have resorted to banditry, kidnapping, ritual killings, prostitution, terrorism, child trafficking, yahoo yahoo plus and other innumerable nefarious acts as a result alarming rate of unemployment in the country. This paper unequivocally x-rays the survival strategies for Nigerian youths amidst obstacles in Nigeria. Also, it exposes some of the barriers that could militate against survival strategies. This paper is purely conceptual in nature. The survival strategies include POS Business, Graphic Designs, Food Community Business, Home Lessons, Writing and Selling of E-Books, Home Cleaning Services, Affiliate Marketing e.t.c. while the barriers include Negative Mindset, Pride(the killer of destiny),paucity of vision and faith, religious fraud. We concluded that Nigerian Youths need to desist from seeking white collar jobs to creating viable jobs for themselves and others via the entrepreneurial activities deliberated on so far. We, therefore, recommend and encourage youths to just positively do what they can with all they have, wherever they are and the sky will be their stepping stones.

Coverage Motion Planning Based on 3D Model’s Curved Shape for Home Cleaning Robot

Research on the automated control of robots for wiping curved surfaces includes studies on cleaning contaminated areas and controlling the end-effector posture to apply a constant force along curved surfaces. However, such robots should also clean difficult-to-find contaminants such as dust and dirt. One of previous studies has considered motion generation as a generalized traveling salesman problem. In particular, a point cloud is acquired from an RGBD camera, and a large graph is created to represent the surface based on the point cloud. The system then finds an appropriate end-effector posture for each node and sets up multiple coordinate systems. Consequently, an efficient cleaning motion can be generated; however, path generation using the previous study is a highly time-consuming process. Therefore, in this study, a 3D model is used to generate cleaning actions more efficiently. A point cloud is then generated from the mesh data of the 3D model, based on which the surface is represented as a simple graph that can be solved as a traveling salesman problem, thereby reducing the computational time. The optimal end-effector posture is determined based on the shape of the surface and is set as the coordinate system for each node. Finally, experiments are conducted to compare the cleaning results with the previous study results, thereby verifying that results can be obtained in less than one-tenth the computational time required for the previous study results.

COVID-19 lockdown: Impact on emotional well-being and relationship to habit and routine modifications

We examine the impact of the COVID-19 lockdown on emotional well-being and its relationship to habit and routine modifications in a sample of 584 participants aged 18-65 (M age = 35.3; 75.3% females) on lockdown in Spain. Participants assessed their perceived changes in emotional well-being during the lockdown. They reported a perceived increase in negative affect and a perceived decrease in positive affect during this period, compared to before. Regarding habits and routines, there was an increase in media and social media consumption, home cleaning and tidying up, eating and sleeping, cooking and baking, reading, talking or doing activities with other people in the home, and handwashing. Increases in media and social media use, eating, and doing nothing were significantly associated with an increase in negative affect and a decrease in positive affect. Overall, the results highlight the importance that leisure activities have in determining emotional well-being during the lockdown.

Survey of Home Cleaning Practices With Noninvasive Ventilation Equipment

Purpose: Home noninvasive ventilation (NIV) equipment is often observed to be dirty, potentially increasing patients' risk of respiratory infection. This study aimed to describe the cleaning practices of home NIV patients. Methods: This single-site, cross-sectional, observational study surveyed 100 patients from the respiratory failure clinic regarding cleaning instructions, cleaning habits, barriers, and motivators to cleaning. Open-ended responses were analyzed with basic content analysis and closed categorical responses with frequencies and percentages. Results: Of 100 participants, 77% responded. Cleaning instructions most commonly recalled included cleaning with soapy water for masks (26/47, 55%), head straps (19/47, 40%), and tubing (21/47, 45%); vinegar solution for humidifiers (9/39, 23%); and replacing filters (14/39, 36%). Fourteen respondents reported barriers to cleaning, including forgetfulness (7/14, 50%) and physical difficulties (6/14, 43%). Commonly reported cleaning practices included soapy water to soak masks (28/77, 36%) and tubing (35/77, 46%), weekly masks (34/77, 44%) and tubing cleaning (29/77, 38%), vinegar solution to clean humidifiers for the 36 humidifier users (15/36, 44%), monthly humidifier cleaning (13/36, 36%), and monthly filter cleaning/replacement (36/77, 47%). Conclusion: Few respondents could recall specific instructions about when and how to clean their equipment. Many reported routine cleaning, with varied methods and frequencies. Our results will inform future NIV equipment cleaning educational package design.

A VIKOR-BASED APPROACH FOR DETERGENT SELECTION PROBLEM FROM SUSTAINABILITY PERSPECTIVE

The sustainability concept is getting more important due to the limited world carrying capacity and natural resources with increasing population around the world. As one of the Fast-Moving Consumer Goods, home cleaning has different impacts on both environment and health. In this context, using detergents reveal a research area because, they consist many ingredients that are worth to consider for sustainability and innovation. In daily life, detergents are consumed almost in every type of household activity; therefore, there is an increasing amount of detergent consumption. Even type of consumed detergent differs in terms of different regions, the most consumed type is defined as powder detergents according to European statistics. Such real-life cases complicate the decision-making process even more difficult because, they combine both qualitative and quantitative issues. In such cases, multi-criteria decision-making methods deal with uncertainties exist and contradicted criteria. Thus, the aim of the application is to detect the most appropriate detergent according to the sustainability dimensions by Vikor Method. First of all, five most purchased powder detergents were determined from top FMCG companies’ annual reports and some related articles in literature. Secondly, algorithm of the Vikor Method was coded on MATLAB R2018a software and then, gathered data was integrated to evaluate the identified powder detergent options under sustainability metrics. As a result of this study, the most effective criteria are active ingredient and foam height from customer perspective without considering market share and retail price per net weight. Companies should focus on reducing negative effects of active ingredients while satisfying customer expectations and this ensures the preferability of a powder detergent from sustainability perspective.

The Importance of Home Cleaning: Sediment Transport by Alpheid Shrimps Provides a Competitive Advantage to Their Host Anemones

Bartholomea annulata is a facultative host of the A. armatus species complex. In the Mexican Caribbean it is commonly found in cracks and crevices located where the vertical walls meet the sandy bottom or on large coral patches away from the sand. To protect themselves from predators, anemones often contract their hydraulic body into a cavernous den and extend the stinging tentacles toward the entrance. The high sediment dynamics of the region, however, result in a permanent risk of animal shelters to be obstructed by sand. By both analysing field data and conducting laboratory experiments with artificial shelters, the present study explored the den cleaning behaviour widely extended amongst alpheid shrimp, and its role in the alpheid-anemone symbiotic interaction. Videorecordings showed that den cleaning was composed of three main behaviours: digging, tossing and tamping. It commenced as soon as 7.2 ± 10.5 min after anemones were recognised by alpheids, and behaviours were displayed systematically amongst all 12 replicates. Despite being completely burrowed in sand, Alpheus spp. were capable of finding the anemone and liberating the entrance of the artificial shelters in less than 2.5 h. In addition, manipulative experiments showed that anemones confronted with shelters that were obstructed with sediment had a 25% probability of fully retracting when Alpheus spp. were absent, compared to a 75% probability when shrimps had cleaned the shelter’s entry and internal passage. The analysis of field data indicated that the presence of alpheid shrimps as symbionts of B. annulata was 30% higher amongst anemones in close contact with sandy bottoms than when inhabiting crevices on the top or lateral walls of hard substrates, away from the sediment. Overall, our study concludes that den cleaning constitutes a quick and effective mechanism to assure the anemone’s full retraction into their den, and by keeping the sediment away, alpheids provide the necessary conditions that serve both the anemone’s and the shrimp’s higher chances of acquiring maximum protection from predators. This advantageous exchange in protection partially explains why alpheids are more frequently present in B. annulata in interface microhabitats where the benefit of the interaction is maximised.

Hygiene hypothesis: association between hygiene and asthma among preschool children in Lebanon.

To validate a scale to assess the hygiene hypothesis and the association between hygiene and asthma among Lebanese preschool children aged 3-5 years. This cross-sectional study, conducted between November 2018 and March 2019, enrolled 515 preschool children. Asthma and potential risk factors, including hygiene, were assessed using a standardized questionnaire. A specific hygiene hypothesis scale has been generated and validated for this purpose. The hygiene hypothesis scale items converged over a solution of nine factors that had an Eigenvalue over 1, explaining a total of 65.86% of the variance. An acceptable Cronbach's alpha value was recorded for the hygiene hypothesis scale (0.696). Variables correlated with higher odds of asthma were male gender (ORa = 0.41 for females), living near a prairie sprayed with pesticides (ORa = 3.09), having a heating system in the bedroom compared to the sitting room (ORa = 9.97), attending kindergarten (ORa = 2.80), having a mother who smokes waterpipe compared to not smoking (ORa = 3.34), having a mother with a history of asthma (ORa = 5.50), and having respiratory infections (ORa = 14.72). However, the hygiene hypothesis score was not associated with higher odds of asthma (p = 0.881). The current results suggested that neither home cleaning nor personal cleanliness was correlated with asthma in preschool children. Larger prospective studies that measure the intensity and duration of exposure to each toxicant are suggested to better assess the hygiene hypothesis items and their association with asthma.

Impact of the coronavirus disease 2019 pandemic on the Palestinian family: A cross-sectional study.

Introduction:The current study aims to understand and assess the consequences of the coronavirus disease 2019 pandemic on Palestinian families.Methods:This online community-based cross-sectional descriptive study was conducted between 19 April 2020 and 5 June 2020, using a validated questionnaire. The questionnaire comprised of three sections: sociodemographic characteristics, living conditions, and impact of the coronavirus disease 2019 pandemic. A convenience sampling method was used to select participants.Results:A total of 570 adults aged ⩾18 years participated in the study. Of them, 258 (45.3%), 120 (21%), and 192 (33.7%) were residing in the Gaza Strip, West Bank, and East Jerusalem, respectively. A large portion of participants (73.2%) reported that the containment measures of the coronavirus disease 2019 pandemic had caused an excessive burden on their families; 549 (96.3%) revealed that water supplies were not always available at home. However, paying attention to personal hygiene and home cleaning was more than usual before the announcement of the coronavirus disease 2019 pandemic. The mean times of going out of their homes have dropped significantly following the onset of the pandemic, p value = 0.001 (95% confidence interval). In addition, 192 (33.7%) participants reported that they changed to working remotely from home with 66 (11.6%) having lost their employment.Conclusion:The coronavirus disease 2019 pandemic was associated with an additional burden on the Palestinian families. Moreover, we suggest discussing the obtained results with local and national stakeholders to ensure that they know to improve their actions.

Management of Pregnancy during the COVID-19 Pandemic.

Coronavirus disease 2019 (COVID‐19) is spreading worldwide. All aspects of pregnancy management from conception to delivery to puerperium as risks facing newborns are herein, reviewed. Maternal home management and prenatal care management protection, delivery timing or mode selection, delivery process management, and subsequent puerperal protection are crucial. In this Review, the features and treatment strategies, especially emphasizing the safety of antiviral drugs for pregnant women, the wearing of face masks, and practicing of personal hygiene (e.g., handwashing, disinfection, home cleaning, and ventilation) are reviewed as essential protective measures. It is recommended to provide online consultation, telemedicine, and remote fetal heart rate monitoring and set the flow point for prenatal examination to encourage prenatal examination at home or postponing examinations (except nuchal translucency at 11‐13+6 weeks, Oscar Test at 16 weeks, and fetal ultrasound at 20–24 weeks). It is shown that the precise formulation of follow‐up strategies for pregnant women with COVID‐19 is necessary.

Assessing domestic environmental impacts through LCA using data from the scientific literature

The aim of this paper is to provide an overview about the distribution of the environmental impacts arising from different domestic functions (i.e. storing and preparing food, washing dishes, watching television, reading, personal cleaning, washing, drying and ironing clothes, home cleaning, heating, cooling, lighting and mobility) typically performed within a common family home. The method has general validity but for reasons related to the availability of data in the literature it has been applied by way of example only in three EU countries: Italy, Germany and France. The study was performed by using Life Cycle Assessment (LCA) in accordance with international standard ISO 14067 for determining the carbon footprint of different alternative domestic components, mainly appliances, for each function, by exclusively exploiting data from scientific literature. The functional unit is defined comprising all most common referred domestic activities of a family of three members within a house of 100 m2. The study identified an optimal configuration and a worse one of the domestic components in terms of carbon footprint, showing how a wise choice of these can greatly affect the overall impact by reducing it compared to the worst by more than 22% in Italy, 45% in Germany and 56% in France. The average impacts between the optimal and the worst configurations of Germany are higher than Italy (+27%) and France (+44%). Considering the impacts among the domestic functions in the average configuration, mobility was the most impactful in all the three countries (35–48%), followed by heating (17–26%), personal cleaning (10–13%) and washing dishes (8–13%), while cooling is consistent only in Italy (13%), against 5% in Germany and 2% in France. The study also allowed to identify some generic criteria for defining the optimal configuration: the increasing in energy efficiency, the choice of the least impacting energy source depending on the geographical location, ensuring water savings and the early replacement of older domestic components. Finally, by comparing some common measures for improving the domestic sustainability, these criteria proved to be more effective than solar systems and improved electricity mix. The provided outcomes may be used by manufacturers for improving their product in a more sustainable way as well as by legislator and end user, respectively for boosting and choosing the greener domestic components.
