Incidence and risk factors associated with atrioventricular block in the general population: the atherosclerosis risk in communities study and Cardiovascular Health Study

ObjectivesTo identify risk factors correlated with atrioventricular block (AVB) in the general population.MethodsParticipants in the Atherosclerosis Risk in Communities study (ARIC) and the Cardiovascular Health study (CHS) were enrolled. The presence of AVB was confirmed at an electrocardiogram (ECG) reading center using Minnesota ECG Classification. Cox proportional hazards models were performed to investigate potential risk factors of AVB, after adjustment for age, sex, race and traditional cardiovascular risk factors.ResultsDuring the 17 years of follow-up, a total of 731 high-degree AVB cases were identified. Age and sex-standardized rate of AVB was 2.79 and 2.35 per 1000 person-years in the white and the black population, respectively. With the increase of the geriatric population, the incidence of high-degree AVB will increase from 378,816 in 2020 to 535,076 in 2060, and most increment would occur among the elderly. Older age, male sex, the white race, overweight, comorbidities, declined forced vital capacity (FVC), elevated inflammation biomarkers, left bundle branch block and bifascicular block were independently associated with the incidence of high-degree AVB.ConclusionTo conclude, older age, male sex, white population, overweight, combined diabetes or chronic kidney disease, impaired FVC, elevated inflammation biomarkers, left bundle branch block and bifascicular block were independent predictors for high-degree AVB. The next 40 years would witness a dramatic increase in the incidence of high-degree AVB.

The effects of climate and population on human land use patterns in Europe from 22ka to 9ka ago

Between 22ka and 9ka ago, after the Last Glacial Maximum (LGM) and during the transition to the Holocene, mobile hunter-gatherer populations, differentiated by their stone tool assemblages, periodically dispersed and contracted across Europe. It is well understood that climate played an important role in human distributions and population sizes during the post-LGM Late Pleistocene and Early Holocene, but the question remains as to whether increasing population sizes drove early human dispersal. Here, using a spatiotemporal species distribution model to infer the fundamental and potential human climatic niche space of Late Upper Paleolithic, Final Paleolithic and Early Mesolithic Europe, and hypotheses derived from the Ideal Distribution Model, we test i) how changes in climate affected the size and extent of the projected potential human niche space, ii) for effects of changes in size of projected potential niche on regional human population sizes, iii) whether increasing human population sizes drove human dispersal into less climatically suitable habitats, and iv) whether populations associated with different high-order material culture groupings (macro-level technocomplexes) occupied different climatic spaces. We find that changes in climate correlate strongly with the size and extent of the projected potential human niche space, that increases in the projected human niche space correlate with increases in human population, that human population size is just beginning to become large enough to influence land use and dispersal patterns at the Pleistocene-Holocene transition, and that archaeological technocultural entities overlap in their fundamental climatic niche space. This overlap implies that changing tools forms cannot readily been seen as reflecting adaptations to changing climates.

Sustainable development goals, governance and assessment of the impact of urban growth on vegetation cover in Benin City, Nigeria, using land-use–land-cover change trajectories

Land-use/cover (LULC) and governance are key elements in the attainment of the Sustainable Development Goals. This study focused primarily on LULC changes in Benin City, Nigeria, from 1992 to 2022; to examine how urban growth affected vegetation cover across four time points: 1992, 2002, 2015 and 2022. Variable LULC classifications considered included: built-up areas, open spaces/bare lands, vegetations, waterbodies and wetlands. In three decades (1992–2022), increases in the built-up, open space/bare land and wetland LULC were observed and attributed to population increases and higher infrastructural demands whereas evident reductions in the sizes of vegetation and waterbody categories were ascribed to anthropogenic activities and climate events. The average annual rates of change in the built-up and vegetation LULC increased (7.28%) and decreased (−3.02%), respectively, between 1992 and 2022; with the built-up area experiencing a 218% increase from 6493 to 20,672 (km2) whereas vegetation decreased by 90% from 23,445 to 2239 (km2). The corollary is that urban growth, exemplified by the built-up LULC, was progressive while vegetation cover was depleted, in the 30-year period. Changes in five other periods were also interrogated. Government and stakeholders-promoted afforestation and agroforestry programs are recommended as plausible solutions to check vegetation-cover depletion. Other solutions proffered include the support of relevant farmers’ trainings in climate-smart and hydroponic agriculture, and the application of sustainable farming techniques. Policymakers and estate developers/managers should encourage sustainable land governance and cities with resilience and coping capacities; to tackle the problem of climate change, with high emphasis on green area developments.

Plant community‐specific greening patterns predict population size increases in a temperate herbivore

Climate change‐driven impacts on vegetation productivity have been shown to drive mammalian herbivore population dynamics in Arctic and alpine environments. However, there is less evidence for temperate systems. To address this, we examined the contribution of increasing plant biomass in different vegetation communities (measured by NDVI, normalised difference vegetation index) and winter weather on the observed long‐term upward trend in the population of the Soay sheep of Hirta, St Kilda, UK. We found that biomass had increased in all vegetation communities present and increased the fastest in vegetation types preferred by the sheep. Specifically, those communities with high specific leaf area and Ellenberg's N, low leaf dry matter content. Peak summer NDVI and either winter average wind speed or winter North Atlantic Oscillation data added to the variance explained by a simple density dependence model of yearly sheep population growth rates. The highest explanatory power was found for preferred vegetation types including maritime cliff communities dominated by Plantago species, but also for both inaccessible (Rumex acetosa‐dominated) or unpreferred (Eriophorum vaginatum‐ or Sphagnum‐dominated) communities where seasonal variation more closely reflects productivity due to minimal grazing. Although the climate is getting windier and wetter, it is also getting warmer allowing increased plant productivity and this appears to be behind the long‐term increases in the Soay sheep population. Our study indicates that analysing key vegetation communities may reveal these links better than using landscape‐level averages, and that oceanic‐temperate systems may show similar climate‐driven herbivore population trends to those reported in Arctic and alpine systems.

The anticancer potential of tetrahydrocurcumin-phytosomes against oral carcinoma progression

BackgroundHerbal medicine combined with nanotechnology offers an alternative to the increasing burden of surgery and/or chemotherapy, the main therapeutics of oral carcinoma. Phytosomes are nano-vesicular systems formed by the interaction between phospholipids and phyto-active components via hydrogen bonding, exhibiting superior efficacy over pure phytocomponents in drug delivery.MethodsTetrahydrocurcumin (THC)-phytosomes were prepared by thin film hydration method. After characterization, in vitro cytotoxicity, antiproliferative capacity, antioxidant potential and full apoptotic workup were paneled on oral squamous cell carcinoma (SCC4) in comparison with native THC-solution and cisplatin (3.58 µg/mL intravenous injection), as positive controls. In addition, we tested the three medications on normal oral keratinocytes and gingival fibroblasts to attest to their tissue-selectivity.ResultsSuccessful preparation of THC-phytosomes using 1:1 molar ratio of THC to phospholipid exhibited significantly increased aqueous solubility, good colloidal properties, and complete drug release after one hour. On SCC4 cells, THC-phytosomes, at their dose-/time-dependency at ~ 60.06 µg/mL escalated cell percentages in the S-phase with 32.5 ± 6.22% increase, as well as a startling 29.69 ± 2.3% increase in apoptotic population. Depletion of the cell colonies survival to 0.29 ± 0.1% together with restraining the migratory rate by -6.4 ± 6.8% validated THC-phytosomes’ antiproliferative capacity. Comparatively, the corresponding results of THC-solution and cisplatin revealed 12.9 ± 0.9% and 25.8 ± 1.1% for apoptosis and 0.9 ± 0.1% and 0.7 ± 0.08% for colony survival fraction, respectively. Furthermore, the nanoformulation exhibited the strongest immuno-positivity to caspase-3, which positively correlated with intense mitochondrial fluorescence by Mitotracker Red, suggesting its implication in the mitochondrial pathway of apoptosis, a finding further explained by the enormously high Bax and caspase-8 expression by RT-qPCR. Finally, the THC groups showed the lowest oxidative stress index, marking their highest free radical-scavenging potential among the test groups.ConclusionsTHC-phytosomes are depicted to be an efficient nanoformulation that enhanced the anticancer efficacy over the free drug counterpart and the conventional chemotherapeutic. Additionally, being selective to cancer cells and less cytotoxic to normal cells makes THC-phytosomes a potential candidate for tissue-targeted therapy.

Natural Autophagy Activators to Fight Age-Related Diseases.

The constant increase in the elderly population presents significant challenges in addressing new social, economic, and health problems concerning this population. With respect to health, aging is a primary risk factor for age-related diseases, which are driven by interconnected molecular hallmarks that influence the development of these diseases. One of the main mechanisms that has attracted more attention to aging is autophagy, a catabolic process that removes and recycles damaged or dysfunctional cell components to preserve cell viability. The autophagy process can be induced or deregulated in response to a wide range of internal or external stimuli, such as starvation, oxidative stress, hypoxia, damaged organelles, infectious pathogens, and aging. Natural compounds that promote the stimulation of autophagy regulatory pathways, such as mTOR, FoxO1/3, AMPK, and Sirt1, lead to increased levels of essential proteins such as Beclin-1 and LC3, as well as a decrease in p62. These changes indicate the activation of autophagic flux, which is known to be decreased in cardiovascular diseases, neurodegeneration, and cataracts. The regulated administration of natural compounds offers an adjuvant therapeutic alternative in age-related diseases; however, more experimental evidence is needed to support and confirm these health benefits. Hence, this review aims to highlight the potential benefits of natural compounds in regulating autophagy pathways as an alternative approach to combating age-related diseases.

Exploring the urban-rural dichotomies in post-pandemic migration intention: Empirical evidence from Europe

Since the beginning of the 21st century, we have been living in the ‘urban century’, characterised by a rise in the number of cities and mega-cities and a structural population increase in most cities, to the detriment of rural areas. Given the declining interest in rurality, the aims and scope of this paper are to map out the complex force field of rurality versus urbanity, and explore if the COVID pandemic has become a ‘game changer’ that thus may swift the existing patterns. Relying on multilevel modelling, to also account for between-country differences, and using Eurobarometer data on post-pandemic migration intention in both rural and urban areas, our results do not find support for a major post-covid urban exodus. Younger individuals from large cities are indeed more willing to leave for rural areas when they are convinced that they can play an active role in the local decision-making process. Teleworking, as well as EU concrete actions for addressing environmental issues, may also drive more migration toward rural areas. On the other hand, poor access to health services may push individuals towards urban areas. In policy terms, our findings advocate for improving access to public services in rural areas. In addition, the study reinforces the role of the Cohesion Policy to urge the twin transition, as facilitating teleworking and strengthening the environmental commitment were shown to make rural areas more appealing.

Design and Development of Virtual Reality Application Implementing Age-Friendly Care and the 4Ms: A Quality Improvement Project.

With an increase in the aging population, the application of evidence-based practice in geriatric education can strengthen knowledge, skills, and clinical experience for healthcare students caring for older adults. The Age-Friendly Health System (AFHS) is one of the frameworks founded on providing evidence-based and low-risk care centered on what matters most to older adults, their families, and caregivers. Virtual reality (VR) platforms are gaining popularity due to their ability to provide an immersive, hands-on learning experience resembling an actual medical practice or care setting. Immersive learning enhances students' sensory perceptions, promoting an innovative and engaging way of acquiring concepts that are difficult to teach in real life. This study aimed to design, develop, implement, and evaluate a case-based training module highlighting AFHS and educating medical students on the 4Ms approach in geriatric care (What Matters, Medication, Mentation, and Mobility). The project was a feasibility study completed in two phases. Phase one included planning and developing a case-based scenario incorporating the 4Ms of AFHS. Phase two included implementing and evaluating the VR training module into the geriatric curriculum for medical students. The final VR case displays a hospital and post-acute setting where an elderly patient is admitted for a hip fracture. Students learn how to triage and treat patients from admission to discharge while demonstrating their knowledge of AFHSs. Approximately 10% of students completed the evaluation survey, and preliminary results indicate significant knowledge change in pre-post scenario-based training on an AFHS. The VR education platform and embedded scenario promise an innovative adaptation of technology in learning the concepts of the 4Ms of AFHSs. However, future studies should explore VR education with clinical assessment evaluation to ensure competence in providing age-friendly care.

Daughters and daughters-in-law providing elderly care: a qualitative study from Karachi, Pakistan

Background and contextProviding care to the elderly is an emerging area of interest due to the increase in elderly population not only in the developed world but also in low and middle income countries. In Pakistan a country with an overall population of over 200 million, the elderly population amounts to 11.3 million. Caregiving of the elderly tends to occur within the kinship motivated by sociocultural norms as well as absence of government support facilities. While quantitative literature exists in Pakistan describing the “caregiver’s burden,” an in-depth analysis into the experiences of familial caregivers is missing.MethodsThe research used qualitative methods with the aim to explore the lived experiences of 7 daughters and 3 daughters-in-law, living in Karachi, Pakistan providing care to the elderly requiring assistance in at least two tasks of daily living.ResultsFive themes were developed inductively through the phenomenological method. All participants were Muslim and belonged to the upper economic strata of the society. Findings reveal that obligations to care are dominant in kinship circles particularly among women. Participants highlighted the importance of elderly in the Pakistani society, especially due to the religious lens that considers them as blessings. Daughter caregivers spoke about caregiving of their parents as a form of role reversal, emphasizing also upon the life-long emotional bond that served as a strong motivator. On the other hand, for daughter-in-law caregivers, motivations to care also stemmed from social expectations and kinship obligations. All participants reported multiple difficulties during the caregiving experience, despite existence of paid formal help, with respect to balancing multiple role demands and the nature of caregiving that requires constant effort. Results also illustrate that despite the desire to care for the elderly within a collectivist and patrilocal society, participants experienced multiple physical and emotional effects. However, a few also reported an increase in self-mastery and self-worth.ConclusionThis study reveals that despite increasing urbanization and more women working outside the home, providing care to the elderly appears to be centered within the kinship circle. The research makes important contributions to the ageing literature in Pakistan with relevance to other South Asian contexts.

The Importance of Orthostatic Increase in Pulse Wave Velocity in the Diagnosis of Early Vascular Aging.

Background/Objectives: Vascular aging can be assessed by arterial stiffness measured through pulse wave velocity (PWV). Increased PWV predicts arterial hypertension, cardiovascular events and all-cause mortality. Detection of early signs of vascular aging remains an unmet problem. To search for the most sensitive markers for the early increase in vascular stiffness in a healthy population. Methods: One-hundred and twenty healthy subjects were divided in three equal age groups: <30 years, 30-45 years and >45 years. Head-up tilt test (HUTT) protocol was applied, providing a standardized hydrostatic column height. PWV at the brachial-ankle artery site (baPWV) was measured using a multichannel sphygmomanometer ABI System 100 PWV in three positions: in the baseline horizontal (supine) position-baPWVb; during the head tilt-up with an individual angle of inclination-baPWVt; and when returning to supine. Results: The most sensitive marker of early stiffness increase in a healthy population is the relative orthostatic increase in baPWV, ΔbaPWV/baPWVb, where ΔbaPWV = baPWVt - baPWVb. The significance of differences in this parameter between the young and elderly groups reached p = 0.000075 and p = 0.000006, respectively. Conclusions: The proposed index ΔbaPWV/baPWVb can be considered as a promising sensitive early biomarker of vascular aging and as a potential effective indicator in cardiovascular prevention. A longitudinal cohort study is needed to confirm this assumption.

Inequalities in Water Insecurity in Kenya: A Multidimensional Approach

Water insecurity is a global concern likely to be compounded by increases in population and climate change. Existing water insecurity measurement methods capture multidimensional deprivation only at regional or sub-regional levels. Such estimates do not capture heterogeneous household experiences of water supply, proximity to water sources and affordability, which can vary substantially from regional averages. Accurate measurement requires a method that captures the incidence and intensity of a household’s simultaneous deprivation in dimensions of water accessibility, affordability, sufficiency and safety. We propose such a method and assess related inequalities using an approach analogous to the Alkire–Foster methodology for multidimensional poverty. Using household-level data from the Kenya Integrated Household Budget Survey 2015/16, we find that 63% of the Kenyan population experience multiple deprivation in water access. The dimensions of water affordability and sufficiency contribute most to multidimensional water insecurity, highlighting the need to ensure an adequate supply of affordable water. Disparities by household place of residence, dwelling type, and socio-economic status are evident. The estimates of multidimensional water insecurity are robust to different deprivation and poverty cutoffs. Our analysis is an invitation to rethink water insecurity metrics, allowing water deprivation to be measured more frequently and with greater precision to understand its impact clearly.

Vertical Farming: A Promising Solution to Urban Agriculture

Urban agriculture refers to the agricultural activities such as plant production for home consumption and income generation in the urban areas especially cities. The concept of urban agriculture has been popularizing but in today’s century it is also facing certain problems such as limited land resources, population increase etc. Vertical farming is a type of urban agriculture, through which we could seek solutions to the problems that urban agriculture has been facing in the recent times. Vertical farming refers to the growing of crops in vertically stacked structures especially under controlled environmental conditions and using a suitable growing medium to increase the crop production per square metre by utilizing the vertical space for cultivation [1]. A wide range of crops can be cultivated in vertical farming with the use of techniques such as hydroponics, aeroponics, aquaponics, artificial lighting, inside the controlled environment of a greenhouse. Vertical farming is needed to provide solution to the problems of urban agriculture in terms of providing food security to the growing population, efficient land utilization, water conservation, increased crop production etc. However, vertical farming has certain disadvantages as well such as high initial investment cost, high energy cost and high maintenance cost. Therefore, further research and development strategies are necessary to overcome such disadvantages for increasing its effectiveness to meet the food demands of the growing population as well as the future generation in a sustainable manner.

Impact of environmental factors on the coevolution of information–emotions–epidemic dynamics in activity-driven multiplex networks

Abstract During public health emergencies, the diffusion of negative information can exacerbate the transmission of adverse emotions, such as fear and anxiety. These emotions can adversely affect immune function and, consequently, influence the spread of the epidemic. In this study, we established a coupled model incorporating environmental factors to explore the coevolution dynamic process of information–emotions–epidemic dynamics in activity-driven multiplex networks. In this model, environmental factors refer to the external conditions or pressures that affect the spread of information, emotions, and epidemics. These factors include media coverage, public opinion, and the prevalence of diseases in the neighborhood. These layers are dynamically cross-coupled, where the environmental factors in the information layer are influenced by the emotional layer; the higher the levels of anxious states among neighboring individuals, the greater the likelihood of information diffusion. Although environmental factors in the emotional layer are influenced by both the information and epidemic layers, they come from the factors of global information and the proportion of local infections among surrounding neighbors. Subsequently, we utilized the microscopic Markov chain approach to describe the dynamic processes, thereby obtaining the epidemic threshold. Finally, conclusions are drawn through numerical modeling and analysis. The conclusions suggest that when negative information increases, the probability of the transmission of anxious states across the population increases. The transmission of anxious states increases the final size of the disease and decreases its outbreak threshold. Reducing the impact of environmental factors at both the informational and emotional levels is beneficial for controlling the scale of the spread of the epidemic. Our findings can provide a reference for improving public health awareness and behavioral decision-making, mitigating the adverse impacts of anxious states, and ultimately controlling the spread of epidemics.

Determination of Heavy Metal Concentrations at Ewu-Elepe, Ikorodu Dumpsite, Lagos, Nigeria

Heavy metal contamination of soil at dumpsites poses risks and hazards to humans and the ecosystems through inhalation of dust particles or dermal contact with the contaminated soil. Dumpsites are usually located at the outskirts of residential areas, but due to population increase in the urban centers as result of rural-urban movement which has become living habitats without considering the health implications. Thus, Ewu-Elepe dumpsite, located on the outskirts of Ikorodu, Lagos may pose a serious threat to residents of this area due to the improper disposal and ineffective management of waste at the dumpsite also, due to the metalic health issue recorded in this area. Therefore, this study was designed to determine the Heavy Metal Concentrations (HMC) and identify the type of Key Environmental Indicators (KEIs) responsible for the heavy metal contamination at the dumpsite. The Principal Component Analysis (PCA), Nemerow Integrated Pollution Index (NIPI), and Pollution Index (PI) procedures were adopted. The Akaike Information Criteria (AIC) was employed to determine the best KEI responsible for the presence of a particular heavy metal on the dumpsite. The Heavy Metals (HMs) found on the dumpsite were Zinc, Copper, Lead, Cadmium, Calcium, Manganese, and Iron. The identified KEIs on the dumpsite were: potential Hydrogen (pH), Electrical Conductivity (EC), Total Organic Carbon (TOC), Total Nitrogen (TN), Phosphorous (P), and Carbon Exchange Capacity (CEC). The AIC at 5% showed that the most significant KEI responsible for Zn was EC with the least value (16.21), pH for Pb (26.70), P for Ca (20.71), TOC for Cu (24.61) and Mn (81.09), TN for Cd (44.97), and CEC for Fe (41.04). The PCA and NIPI estimates for the heavy metals across the 20 sample points were (1760.57, 3.00); (1825.85, 2.30); (1330.80, 2.60); (1644.68, 2.40); (1602.57, 9.70); (1469.93, 2.40); (1379.85, 3.20); (1872.82, 2.40); (1859.30, 8.40); (1397.56, 2.30); (1995.32, 4.70); (1518.62, 3.10); (1565.33, 1.80); (1332.29, 5.10); (1748.59, 2.50); (1664.70, 3.90); (1792.24, 4.10); (1801.79, 2.30); (1801.18, 2.30); (1743.27, 2.00), respectively, implying that the dumpsite was highly concentrated in HMs. Copper, lead, cadmium, calcium, manganese, and iron highly polluted Ewu-Elepe dumpsite with potential hydrogen, electrical conductivity, total organic carbon, total nitrogen, phosphorous, and carbon exchange capacity as the key environmental indicators for the heavy metals.

Middle Meningeal Artery Embolization for Chronic Subdural Hematoma Using N-Butyl Cyanoacrylate With a D5W Push Technique: A Multicentric North American Study of 269 Patients

BACKGROUND AND OBJECTIVES: As the aging population increases, the incidence of chronic subdural hematomas (cSDHs) is expected to rise. Surgical evacuation, though effective, sees up to 30% recurrence. Middle meningeal artery (MMA) embolization, particularly with n-butyl cyanoacrylate (n-BCA) glue diluted in D5W for distal penetration, has shown promise in reducing recurrences. Limited reports have investigated the safety and technical feasibility of n-BCA as a primary liquid embolic agent using the D5W push technique in cSDH. This series is the largest in the literature investigating the outcomes of this technique in cSDH. METHODS: A multicenter retrospective database analysis was conducted on consecutive patients who underwent MMA embolization using n-BCA embolisate. Data collected included patient demographics, procedural information, angiographic data, and periprocedural complications. RESULTS: The study included 269 patients with a median age of 76 years. Nearly half of the patients had previous surgeries, and 93 underwent contralateral embolization for bilateral cSDH. Successful MMA embolization with effective distal penetration was achieved in all cases. The complication rate was 2.2%. Significant improvements were noted at a 60-day follow-up, with a median reduction in cSDH diameter of 40.6% (P &lt; .001) and 53% of patients showing neurological improvement. No recurrent cSDH or need for retreatment was observed in patients who underwent follow-up. CONCLUSION: MMA embolization using n-BCA with the D5W push technique is safe and technically feasible. It can be used adjunctively or as an alternative to surgery in patients with cSDH, resulting in decreased recurrence, high technical success, improved distal penetration, and low complication rates.

THE WATER CRISIS LOOMS LARGE IN PAKISTAN WHICH MAY FACE ABSOLUTE SCARCITY

Pakistan has the fourth-highest rate of water use in the world, as reported by the IMF (International Monetary Fund), and is the 3rd greatest water-stress country in the world.Water can be scarce for many reasons: water supply is very low compared to demand, infrastructure is inadequate, and institutions fail to balance every person’s daily needs. Water scarcity is a global problem, with the most badly and worse affected communities. In this thesis we can measure Pakistan’s water scarcity with the four main indicators. The four main indicators can be measured in a country’s water scarcity: The Water Poverty Index, Water Resources Vulnerability Index, the Falkenmark indicator, and Physical and Economic Water Scarcity Indicators. Currently, Pakistan is one of the countries where demand of water exceeds over available water supply with the giving of these 4 indicators. There are many reasons for Pakistan’s water scarcity, being increased populace, citified and computerization, climate change, unsatisfactory warehouse, residues in the existing tank, corrupt system efficiency, irrigational problem and traditional methods of farming, and insufficient finance. The possible alternatives to overcome these issues are the construction of small and large dams where possible, the construction proper irrigation system, improving the surface water governance with suitable pricing, controlling the increase in population, improving transportation, changing the existing harvesting patterns by accepting low delta crops and using saline groundwater, in conjunction with independently with salt accepting crops. Nevertheless, a unified approach is required to optimally use water resources.

Exploring the Utilization of Municipal Solid Waste in Sustainable Construction Materials: A Review

Municipal solid waste (MSW) is a growing problem worldwide, as populations increase, and consumption patterns change. It not only causes pollution and health hazards, but it also results in the depletion of resources. Considering this, the utilization of MSW in sustainable construction materials has become a critical area of research. The purpose of this review study is to explore the various ways in which MSW can be utilized in sustainable construction materials such as fired clay bricks, eco-cement, geo-polymer, fly ash (FA), bottom ash (BA), ceramic bricks, municipal solid waste incineration (MSWI), incineration bottom ash (IBA), and coal bottom ash (CBA). This article also helps to understand the properties of waste-based materials and the potential for their use in various applications. This information renders the construction sector to design and develop standard guidelines for the use of waste-based materials. The significance of this review article lies in its potential to transform the construction sector into a more sustainable and resource efficient sector by leveraging the resources that are already available. Integrating waste into construction materials not only averts the waste from landfills and incinerators, but also facilitates the necessity of raw materials and consequently sustains the natural resources. Additionally, the utilization of waste-based building materials can lead to a reduction in the carbon trace of the construction industry, as waste materials often have lower embodied energy compared to traditional building materials. The outcomes of this review will provide valuable insights into the potential of MSW as a resource in sustainable construction and contribute to the development of effective Municipal Solid Waste Management (MSWM) strategies.

The Analysis Study of Prevalence, Diagnosis, and Management of Cataract in Adult Eye: A Comprehensive Systematic Review

Background: Cataract remains a major cause of visual impairment worldwide. However, in many countries cataract surgery is easily available. Cataract surgery is a kind of effective way to deal with cataract, but it is acompanied with many surgical complications and expensive costs that present enormous social and economic problems to a society, especially in the remote and poor areas of developing countries. The aim: The aim of this study to show about prevalence, diagnosis, and management of cataract in adult eye. Methods: By the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) 2020, this study was able to show that it met all of the requirements. Result: Eight publications were found to be directly related to our ongoing systematic examination after a rigorous three-level screening approach. Subsequently, a comprehensive analysis of the complete text was conducted, and additional scrutiny was given to these articles. Conclusion: Cataracts to increase in the near future due to an increase in the aging population and pre-senile cataracts. The current study also provides clinical determinants for cataract and cataract surgery. Since cataract has emerged as a public concern and the cost burden for cataract surgery has increased with an aging population, it is expected that the present study will form a cornerstone for further investigations and the establishment of a public health plan.

Polycentric Urban System, Territorial Development and Resilience of the Rural Population (Extremadura, Spain)

Over the last several decades, cities have seen concentrated development and population increase. It is a global process, still unfinished, that has simultaneously generated strong territorial imbalances because of socioeconomic backwardness and depopulation of rural areas. The alternative proposed by all institutions is a polycentric urban system, so that cities contribute to decentralizing this development towards their respective areas of influence, thus stabilizing the populations in them. Extremadura is a paradigmatic example, since it has a polycentric system of small cities that have been able to retain half of the population in rural areas. The objective of this article, first, is to define the urban structure and, based on this, typify the range, the hierarchy of the system and its territorial distribution, for which a multivariate analysis is applied. Secondly, a series of isochrones and displacement ranges are defined to analyze urban accessibility, which is key to determining the degree of decentralization of development and population stability. However, a wide peripheral and remote strip remains in the region, for which a concrete proposal is finally made for discussion.

Effect of County Government Strategies in the Collection, Transportation and Disposal of Plastic Waste in Lodwar Town, Turkana County Kenya

Plastic waste management has become a major public health and environmental concern in urban areas of many developing countries. Economic growth and population increase in the developing countries in recent years has caused an increase in utilization of natural resources that has led to unprecedented plastic waste generation. The uncontrolled plastic waste disposal has become a challenge in Africa and other developing countries due to insufficient or lack of human and financial capacities to remedy the situation. This study investigated the effect of county governments’ strategies in place in the collection, transportation and disposal of plastic waste in Lodwar town, turkana county Kenya. A cross-sectional descriptive study design was used. purposive sampling was used to select 345 respondents from Lodwar town and the county government employees including key informants from public health department at the county was adopted. Data were then analyzed for descriptive statistics with the aid of Statistical Package for Social Sciences (SPSS) version 26. The study findings showed that majority (78.6%) of the residents disagreed that there is reselling of plastic materials to avoid generation of wastage. Further majority (38%) also disagreed that they are reusing the plastics for other purposes in their households. Additionally, majority (55.9%) still disagreed that the municipality has recycling company, which has assisted in plastic material recycling. However, on the other hand majority (71.6%) of the residents were not aware if there is a new technological recycling machine in the county. The study revealed that majority of the respondents disagreed that there are waste collectors and transporters in the town (mean= 1.95, standard deviation=0.99). Majority of the respondents disagreed that the municipality have recycling company which has assisted in plastic material recycling (Mean=1.51, standard deviation=0.89). Majority of the residents strongly agreed that handling plastic waste in Lodwar municipality is of great concern (Mean=4.59, standard deviation=0.84). The study concluded planning and coordination have a significant effect on plastic waste handling in Lodwar municipality. There are no enough waste collectors and transporters in the town also Municipality has no clear waste management guideline/policy. Recycling methods have a significant effect on plastic waste handling in Lodwar municipality. The study recommended that the municipality administration should come up with waste management guideline/policy that will ensure efficient and reliable wastage handling.
