Florez Niño, Yuliana | 2020

El SARS-CoV-2 (Coronavirus o síndrome respiratorio agudo severo) fue declarado por la OMS como una pandemia en el mundo. Los países latinoamericanos desarrollaron estrategias de aislamiento social para mitigar el contagio y expansión de este virus. Sin embargo, se ha observado que estas medidas esta teniendo repercusiones directas en la salud mental, sobre todo de población vulnerable, como los adultos mayores; afectando en estos la cognición, el estado emocional y conductual. Estos cambios podrían llevar a un incremento de patologías neurodegenerativas provocando un incremento de las demandas de atención sanitaria, mayores costes para el estado y para la familia. Es por ello que un consorcio de Universidades, Centros de Investigación y Clínicas en Latinoamérica y el Caribe nos propusimos analizar el estado cognitivo de los Adultos Mayores en Latinoamérica en el contexto actual de la pandemia, utilizando metodología de telesalud a través de un medio telefónico. Esperamos encontrar un aumento de los indicadores de deterioro cognitivo asociado a factores sociodemográficos y clínicos. Finalmente, esta información creemos permitirá desarrollar estrategias de mitigación e intervención temprana para reducir el riesgo de desarrollar patología demencial.

Global, regional, and national progress towards sustainable development goal 3.2 for neonatal and child health: all-cause and cause-specific mortality findings from the global burden of disease study 2019
...
Paulson, Katherine | 2021-09-04

Background: Sustainable Development Goal 3.2 has targeted elimination of preventable child mortality, reduction of neonatal death to less than 12 per 1000 livebirths, and reduction of death of children younger than 5 years to less than 25 per 1000 livebirths, for each country by 2030. To understand current rates, recent trends, and potential trajectories of child mortality for the next decade, we present the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 findings for all-cause mortality and cause-specific mortality in children younger than 5 years of age, with multiple scenarios for child mortality in 2030 that include the consideration of potential effects of COVID-19, and a novel framework for quantifying optimal child survival. Methods: We completed all-cause mortality and cause-specific mortality analyses from 204 countries and territories for detailed age groups separately, with aggregated mortality probabilities per 1000 livebirths computed for neonatal mortality rate (NMR) and under-5 mortality rate (U5MR). Scenarios for 2030 represent different potential trajectories, notably including potential effects of the COVID-19 pandemic and the potential impact of improvements preferentially targeting neonatal survival. Optimal child survival metrics were developed by age, sex, and cause of death across all GBD location-years. The first metric is a global optimum and is based on the lowest observed mortality, and the second is a survival potential frontier that is based on stochastic frontier analysis of observed mortality and Healthcare Access and Quality Index. Findings: Global U5MR decreased from 71·2 deaths per 1000 livebirths (95% uncertainty interval [UI] 68·3–74·0) in 2000 to 37·1 (33·2–41·7) in 2019 while global NMR correspondingly declined more slowly from 28·0 deaths per 1000 live births (26·8–29·5) in 2000 to 17·9 (16·3–19·8) in 2019. In 2019, 136 (67%) of 204 countries had a U5MR at or below the SDG 3.2 threshold and 133 (65%) had an NMR at or below the SDG 3.2 threshold, and the reference scenario suggests that by 2030, 154 (75%) of all countries could meet the U5MR targets, and 139 (68%) could meet the NMR targets. Deaths of children younger than 5 years totalled 9·65 million (95% UI 9·05–10·30) in 2000 and 5·05 million (4·27–6·02) in 2019, with the neonatal fraction of these deaths increasing from 39% (3·76 million [95% UI 3·53–4·02]) in 2000 to 48% (2·42 million; 2·06–2·86) in 2019. NMR and U5MR were generally higher in males than in females, although there was no statistically significant difference at the global level. Neonatal disorders remained the leading cause of death in children younger than 5 years in 2019, followed by lower respiratory infections, diarrhoeal diseases, congenital birth defects, and malaria. The global optimum analysis suggests NMR could be reduced to as low as 0·80 (95% UI 0·71–0·86) deaths per 1000 livebirths and U5MR to 1·44 (95% UI 1·27–1·58) deaths per 1000 livebirths, and in 2019, there were as many as 1·87 million (95% UI 1·35–2·58; 37% [95% UI 32–43]) of 5·05 million more deaths of children younger than 5 years than the survival potential frontier. Interpretation: Global child mortality declined by almost half between 2000 and 2019, but progress remains slower in neonates and 65 (32%) of 204 countries, mostly in sub-Saharan Africa and south Asia, are not on track to meet either SDG 3.2 target by 2030. Focused improvements in perinatal and newborn care, continued and expanded delivery of essential interventions such as vaccination and infection prevention, an enhanced focus on equity, continued focus on poverty reduction and education, and investment in strengthening health systems across the development spectrum have the potential to substantially improve U5MR. Given the widespread effects of COVID-19, considerable effort will be required to maintain and accelerate progress. Funding: Bill & Melinda Gates Foundation. © 2021 The Author(s).

The impact of SARS-CoV-2 on emotional state among older adults in Latin America
...
Soto-Añari, Marcio | 2021-03-10

In Latin America, the volume of care of infected patients, higher presence of comorbidities among older adults, and restricted access to clinical controls have become this age group into one with the highest risk (Dubey etal., 2020). Under confinement circumstances, older people can experience feelings of helplessness and uncertainty about the future, difficulties to stay focused, anxiety, stress, agitation, withdrawal, and depression (Armitage and Nellums, 2020; Wang etal., 2020). Accordingly, a Consortium of universities, research centers, and clinical centers have joined forces to carry out research which seeks to know the emotional state of Latin American older adults during confinement by Coronavirus disease (COVID-19). The study included the following countries: Argentina, Bolivia, Chile, Colombia, Costa Rica, Ecuador, Guatemala, Honduras, Mexico, Nicaragua, Peru, Puerto Rico, Dominican Republic, and Venezuela. Between April and May, we carry out the piloting of the evaluation protocol, making cultural and linguistic adaptations. Later, between June and October, more than 7000 older adults were evaluated by telephone by an expert professional through filling out an online form. The protocol we used includes a sociodemographic and clinical questionnaire, information on confinement, lifestyles, and the abbreviated version of the Yesavage Geriatric Depression Scale (Martínez de la Iglesia etal., 2020). Sociodemographic characteristics of the final sample (n = 5245) show that 34% are men and 66% are women, with an average age of 69.61 years (SD = 7.28). Average schooling was 10.99 years (SD = 5.85) depending on the country, and 16.7% were illiterate. The major racial pattern of the population is Latin American mestizo (55.1%) followed by white (39.4%), South American indigenous (1.5%), and African American subjects (1.2%). Seventy-seven percentage of the participants have a monthly income, from retirement (45.9%) or independent work (26.4%), and 85% live with their spouses or relatives. Regarding quarantine, 86.7% of the respondents stated that they complied with the confinement measures, with an average of 123.15 days (SD = 42.43) of quarantine, which varies by country. Our data analysis has revealed that 30.27% of the older adults exhibit emotional disturbances. In Mexico and Peru, we have observed the highest levels of geriatric depression (38.9% and 38.1%, respectively) and in Venezuela the lowest (21.35%). Regression analysis shows that more years of schooling (OR = 0.943; IC95%: 0.93–0.95), having an economic income (OR = 0.764; IC95%: 0.64–0.90) and being a Latin American mestizo (OR = 0.832, IC95%: 0.71–0.98) are associated with reduced risk of geriatric depression. On the other hand, being widowed (OR = 1.428; IC95%: 1.10–1.85) or separated (OR = 1.352; IC95%: 1.01–1.82), lived in Bolivia (OR = 1.805; IC95%: 1.31–2.48), Mexico (OR = 2.320; IC95%: 1.70–3.16), and Peru (OR = 2.008; IC95%: 1.45–2.78) are associated with highest risk. This first multicenter study found that emotional status of older adults during the SARS-CoV-2 pandemic in Latin America varies depending on the country where they live and sociodemographic and socioeconomic factors. It is necessary for follow-up studies to validate diagnosis and analyze the greater risk of deterioration in the coming months.

Multiple relationships between aerosol and COVID-19: a framework for global studies
...
Cao, Yaxin | 2021-02-09

COVID-19 (Corona Virus Disease 2019) is a severe respiratory syndrome currently causing a human global pandemic. The original virus, along with newer variants, is highly transmissible. Aerosol is a multiphase system consisting of the atmosphere with suspended solid and liquid particles, which can carry toxic and harmful substances; especially the liquid components. The degree to which aerosol can carry the virus and cause COVID-19 disease is of significant research importance. In this study, we have discussed the aerosol transmission as the pathway of SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), and the aerosol pollution reduction as a consequence of the COVID-19 lockdown. The aerosol transmission routes of the SARS-CoV-2 can be further subdivided into proximal human-exhaled aerosol transmission and potentially more distal ambient aerosol transmission. The human-exhaled aerosol transmission is a direct dispersion of the SARS-CoV-2. The ambient aerosol transmission is an indirect dispersion of the SARS-CoV-2 in which the aerosol act as a carrier to spread the virus. This indirect dispersion can also stimulate the up-regulation of the expression of SARS-CoV-2 receptor ACE-2 (Angiotensin Converting Enzyme 2) and protease TMPRSS2 (Transmembrane Serine Protease 2), thereby increasing the incidence and mortality of COVID-19. From the aerosol quality data around the world, it can be seen that often atmospheric pollution has significantly decreased due to factors such as the reduction of traffic, industry, cooking and coal-burning emissions during the COVID-19 lockdown. The airborne transmission potential of SARS-CoV-2, the infectivity of the virus in ambient aerosols, and the reduction of aerosol pollution levels due to the lockdowns are crucial research subjects.

The role of airborne particles and environmental considerations in the transmission of SARS-CoV-2
...
Shao, Longyi | 2021-04-05

Corona Virus Disease 2019 (COVID-19) caused by the novel coronavirus, results in an acute respiratory condition coronavirus 2 (SARS-CoV-2) and is highly infectious. The recent spread of this virus has caused a global pandemic. Currently, the transmission routes of SARS-CoV-2 are being established, especially the role of environmental transmission. Here we review the environmental transmission routes and persistence of SARS-CoV-2. Recent studies have established that the transmission of this virus may occur, amongst others, in the air, water, soil, cold-chain, biota, and surface contact. It has also been found that the survival potential of the SARS-CoV-2 virus is dependent on different environmental conditions and pollution. Potentially important pathways include aerosol and fecal matter. Particulate matter may also be a carrier for SARS-CoV-2. Since microscopic particles can be easily absorbed by humans, more attention must be focused on the dissemination of these particles. These considerations are required to evolve a theoretical platform for epidemic control and to minimize the global threat from future epidemics

A safe haven of SARS-CoV-2 in the environment: prevalence and potential transmission risks in the effluent, sludge, and biosolids
...
Adelodun, Bashir | 2022-02-22

The novel coronavirus, SARS-CoV-2, which has caused millions of death globally is recognized to be unstable and recalcitrant in the environment, especially in the way it has been evolving to form new and highly transmissible variants. Of particular concerns are human-environment interactions and the handling and reusing the environmental materials, such as effluents, sludge, or biosolids laden with the SARS-CoV-2 without adequate treatments, thereby suggesting potential transmission and health risks. This study assesses the prevalence of SARS-CoV-2 RNA in effluents, sludge, and biosolids. Further, we evaluate the environmental, ecological, and health risks of reusing these environmental materials by wastewater/sludge workers and farmers. A systematic review of literature from the Scopus database resulted in a total of 21 articles (11 for effluents, 8 for sludge, and 2 for biosolids) that met the criteria for meta-analysis, which are then subdivided into 30 meta-analyzed studies. The prevalence of SAR-CoV-2 RNA in effluent and sludge based on random-effect models are 27.51 and 1012.25, respectively, with a 95% CI between 6.14 and 48.89 for the effluent, and 104.78 and 1019.71 for the sludge. However, the prevalence of SARS-CoV-2 RNA in the biosolids based on the fixed-effect model is 30.59, with a 95% CI between 10.10 and 51.08. The prevalence of SARS-CoV-2 RNA in environmental materials indicates the inefficiency in some of the treatment systems currently deployed to inactivate and remove the novel virus, which could be a potential health risk concern to vulnerable wastewater workers in particular, and the environmental and ecological issues for the population at large. This timely review portends the associated risks in handling and reusing environmental materials without proper and adequate treatments.

Use of geospatial tools to predict the risk of contamination by SARS-CoV-2 in urban cemeteries
...
Carollo Toscan, Paloma | 2021-09-28

Urban cemeteries are increasingly surrounded by areas of high residential density as urbanization continues world-wide. With increasing rates of mortality caused by the novel coronavirus, SARS-CoV-2, urban vertical cemeteries are experiencing interments at an unprecedented rate. Corpses interred in the 3rd to 5th layer of vertical urban cemeteries have the potential to contaminate large adjacent regions. The general objective of this manuscript is to analyze the reflectance of altimetry, normalized difference vegetation index (NDVI) and land surface temperature (LST) in the urban cemeteries and neighbouring areas of the City of Passo Fundo, Rio Grande do Sul, Brazil. It is assumed that the population residing in the vicinity of these cemeteries may be exposed to SARS-CoV-2 contamination through the displacement of microparticles carried by the wind as a corpse is placed in the burial niche or during the first several days of subsequent fluid and gas release through the process of decomposition. The reflectance analyses were performed utilizing Landsat 8 satellite images applied to altimetry, NDVI and LST, for hypothetical examination of possible displacement, transport and subsequent deposition of the SARS-CoV-2 virus. The results showed that two cemeteries within the city, cemeteries A and B could potentially transport SARS-CoV-2 of nanometric structure to neighboring residential areas through wind action. These two cemeteries are located at high relative altitudes in more densely populated regions of the city. The NDVI, which has been shown to control the proliferation of contaminants, proved to be insufficient in these areas, contributing to high LST values. Based on the results of this study, the formation and implementation of public policies that monitor urban cemeteries is suggested in areas that utilize vertical urban cemeteries in order to reduce the further spread of the SARS-CoV-2 virus.
