RESUMEN

This research comprehensively assesses the aftermath of Cyclonic Storm Mocha, focusing on the coastal zones of Rakhine State and the Chittagong Division, spanning Myanmar and Bangladesh. The investigation emphasizes the impacts on coastal ecology, shoreline dynamics, flooding patterns, and meteorological variations. Employed were multiple vegetation indices-Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Modified Vegetation Condition Index (mVCI), Disaster Vegetation Damage Index (DVDI), and Fractional Vegetation Cover (FVC)-to evaluate ecological consequences. The Digital Shoreline Assessment System (DSAS) aided in determining shoreline alterations pre- and post-cyclone. Soil exposure and flood extents were scrutinized using the Bare Soil Index (BSI) and Modified Normalized Difference Water Index (MNDWI), respectively. Additionally, the study encompassed an analysis of microclimatic variables, comparing meteorological data across pre- and post-cyclone periods. Findings indicate significant ecological impacts: an estimated 8985.46 km2 of dense vegetation (NDVI >0.6) was adversely affected. Post-cyclone, there was a discernible reduction in EVI values. The mean mVCI shifted negatively from -0.18 to -0.33, and the mean FVC decreased from 0.39 to 0.33. The DVDI underscored considerable vegetation damage in various areas, underscoring the cyclone's extensive impact. Meteorological analysis revealed a 245 % increase in rainfall (20.22 mm on May 14, 2023 compared to the May average of 5.86 mm), and significant increases in relative humidity (14 %) and wind speed (205 %). Erosion was observed along 74.60 % of the studied shoreline. These insights are pivotal for developing comprehensive strategies aimed at the rehabilitation and conservation of critical coastal ecosystems. They provide vital data for emergency response initiatives and offer resources for entities engaged in enhancing coastal resilience and protecting local community livelihoods.

RESUMEN

The Sustainable Development Goals (SDGs) are a global appeal to protect the environment, combat climate change, eradicate poverty, and ensure access to a high quality of life and prosperity for all. The next decade is crucial for determining the planet's direction in ensuring that populations can adapt to climate change. This study aims to investigate the progress, challenges, opportunities, trends, and prospects of the SDGs through a bibliometric analysis from 2015 to 2022, providing insight into the evolution and maturity of scientific research in the field. The Web of Science core collection citation database was used for the bibliometric analysis, which was conducted using VOSviewer and RStudio. We analyzed 12,176 articles written in English to evaluate the present state of progress, as well as the challenges and opportunities surrounding the SDGs. This study utilized a variety of methods to identify research hotspots, including analysis of keywords, productive researchers, and journals. In addition, we conducted a comprehensive literature review by utilizing the Web of Science database. The results show that 31% of SDG-related research productivity originates from the USA, China, and the UK, with an average citation per article of 15.06. A total of 45,345 authors around the world have contributed to the field of SDGs, and collaboration among authors is also quite high. The core research topics include SDGs, climate change, Agenda 2030, the circular economy, poverty, global health, governance, food security, sub-Saharan Africa, the Millennium Development Goals, universal health coverage, indicators, gender, and inequality. The insights gained from this analysis will be valuable for young researchers, practitioners, policymakers, and public officials as they seek to identify patterns and high-quality articles related to SDGs. By advancing our understanding of the subject, this research has the potential to inform and guide future efforts to promote sustainable development. The findings indicate a concentration of research and development on SDGs in developed countries rather than in developing and underdeveloped countries.

RESUMEN

The aim of the present study is to assess soil Cd and Pb contamination in kale (Brassica oleracea var. acephala) production sites in mountain agroecosystem, as well as its potential risk to human health. The study was carried out within 24 kale-production sites located in mountainous region of Rio de Janeiro (Brazil). Soil, plant, and fertilizer samples were collected in all assessed properties. Pseudo-total and bioavailable soil Cd and Pb content and their concentration and amount accumulated in plants were analyzed. The recorded results were used to calculate the pollution index. Risks to human health associated with kale consumption were assessed by comparing the limits set by the Brazilian regulating agency and by calculating estimated daily intake (EDI), noncarcinogenic target hazard quotient (THQ), and carcinogenic risk factor (CRF). Soil Cd and Pb enrichment was observed. Inappropriate management adopted in the assessed sites and terrain slope and the intensive use of mineral (phosphate and potassium) and organic (poultry litter) fertilizers were the main factors contributing to increase soil Cd and Pb pseudo-total and bioavailability contents. Most Cd and Pb contents in leaves, in natura, exceed the maximum values set by the Brazilian regulating agency. The present EDI, THQ, and CRF results recorded for these metals were within the tolerable ranges.

RESUMEN

The current study was developed to evaluate agronomic efficiency and food security of isolated or simultaneous use of two residues-steel slag and fresh or composted poultry litter-in the cultivation of broccoli (Brassica oleracea var. italica). The composition and contribution of toxic and potentially toxic metals by different treatments and contents, translocation, and accumulation of Pb, Cd, Cu, Fe, Mn, and Zn in different plant organs were analyzed. Then, risks to human health associated with consumption of inflorescences were based on the indices of estimated daily intake, noncarcinogenic target hazard quotient, total hazard index (THI), and carcinogenic risk factor (CR), considering adults and children. Steel slag was similar to limestone in terms of the corrective effect of acidity and, despite containing toxic metals, it did not contribute to their higher translocation to inflorescences. Composting favored the concentrations of Pb, Cu, and Zn in poultry litter. The combined use of steel slag and fresh poultry litter and, mainly, composted poultry litter, favored absorption and translocation of Pb for inflorescences, that is, 60.37% and 66.13% of all Pb absorbed, respectively. Consumption of inflorescences from these treatments resulted in the critical THI values of 1.03 and 1.52, respectively, with Pb and Cd being the metals that mostly contributed to the risk. The registered CR was higher than the threshold level of 10-6. The use of steel slag associated with poultry litter favors contamination of broccoli inflorescences and increases risks to human health due to their consumption.

RESUMEN

Droughts are complex natural phenomena that influence society's development in different aspects; therefore, monitoring their behavior and future trends is a useful task to assist the management of natural resources. In addition, the use of satellite-estimated rainfall data emerges as a promising tool to monitor these phenomena in large spatial domains. The Tropical Rainfall Measuring Mission (TRMM) products have been validated in several studies and stand out among the available products. Therefore, this work seeks to evaluate TRMM-estimated rainfall data's performance for monitoring the behavior and spatiotemporal trends of meteorological droughts over Paraíba State, based on the standardized precipitation index (SPI) from 1998 to 2017. Then, 78 rain gauge-measured and 187 TRMM-estimated rainfall time series were used, and trends of drought behavior, duration, and severity at eight time scales were evaluated using the Mann-Kendall and Sen tests. The results show that the TRMM-estimated rainfall data accurately captured the pattern of recent extreme rainfall events that occurred over Paraíba State. Drought events tend to be drier, longer-lasting, and more severe in most of the state. The greatest inconsistencies between the results obtained from rain gauge-measured and TRMM-estimated rainfall data are concentrated in the area closest to the coast. Furthermore, long-term drought trends are more pronounced than short-term drought, and the TRMM-estimated rainfall data correctly identified this pattern. Thus, TRMM-estimated rainfall data are a valuable source of data for identifying drought behavior and trends over much of the region.

RESUMEN

BACKGROUND: Over the past decade, strong evidence for an association between maternal periodontitis and low birthweight has started to appear. However, few intervention studies have been proposed for investigating this hypothesis. The aim of this study was to evaluate whether periodontal therapy among pregnant women would reduce the incidence of low birthweight. METHODS: A nonrandomized intervention study was performed, with two control groups. The sample comprised 339 pregnant women: 141 in the experimental group (treated for periodontitis), 145 in control group 1 (without periodontitis) and 53 in control group 2 (with untreated periodontitis). The experimental group received periodontal treatment throughout pregnancy, whereas control group 1 was only monitored over the same period. After delivery, birthweight information on the newborns was obtained. The analysis procedures consisted of stratified analysis followed by logistic regression. RESULTS: The frequency of low birthweight among the women with treated periodontitis was 9.22%, while it was 13.10% in the group without periodontal disease. However, the difference was not statistically significant (RR 0.72; 95% CI 0.36-1.45). The occurrence of this outcome in the group with untreated periodontitis (24.53%) was greater than in the other two groups. CONCLUSION: This suggests that periodontal therapy is a protective factor for birthweight.

RESUMEN

UNLABELLED: Starting in the 1990s, several authors sought to investigate the hypothesis that periodontitis during pregnancy may contribute towards the birth of low-weight children. However, this relationship is still not well established. The aim of this study was to evaluate whether this oral infection is associated with this gestational event. METHODS: This was a case-control study among 548 puerperae, of whom 164 were the mothers of low-weight live births (case group) and 384 were the mothers of live births of normal gestational weight (control group). They were selected at two public hospital units in two municipalities in the State of Bahia. From interviews and data gathered using live birth cards or birth certificates, information was obtained regarding age, height, previous diseases, marital status, socioeconomic situation, smoking and alcohol use. Mothers who presented at least four teeth on which one or more sites had a probing depth of greater than or equal to 4 mm, clinical attachment loss of greater than or equal to 3 mm and bleeding on probing, at the same site, were deemed to present periodontal disease. The data were analysed by stratification from logistic regression. RESULTS: Periodontal disease was diagnosed in 42.7% of the case group and 30% of the control group. A statistically significant association was found between periodontal disease and low birth weight (unadjusted OR = 1.74; 95% CI: 1.19-2.54), particularly among mothers with low schooling levels (adjusted OR = 2.30; 95% CI: 1.14-4.6). CONCLUSION: The findings suggest an association between periodontal disease and low birth weight among mothers with low education levels.

RESUMEN

AIM: To compare the use of different definitions for exposure measurement in cases of association between periodontal disease (PD) and prematurity and/or low birth weight (PLBW). MATERIAL AND METHODS: A database from a previous case-control study was used to compare four different definitions for periodontitis: at least one site with probing depth > or =4 mm (1); at least one site with clinical attachment loss (CAL)> or =3 mm (2); at least four teeth with one or more sites presenting probing depth > or =4 mm, with CAL> or =3 mm at the same site (3); and at least four teeth with one or more sites with probing depth > or =4 mm, with CAL> or =3 mm at the same site and presence of bleeding on probing (4). The PD frequency, diagnostic values and adjusted association measurements were calculated. RESULTS: PD frequency ranged from 33.1% to 94.7%. Odds ratio(adjusted) varied slightly according to the exposure measurement used. CONCLUSIONS: The association between PD and PLBW weight was consistent, except for exposure measurement 1, i.e. using at least one site with CAL> or =3 mm for periodontitis diagnosis, while the magnitude of this varied according to the definition established.

RESUMEN

BACKGROUND: The clinical importance of systemic bone loss as a contributory factor to alveolar bone loss and the subsequent loss of teeth merits further study, given that osteoporosis and periodontal disease lead to significantly increased morbidity and mortality and higher public expenditure of funds. This case-control study evaluated the association between osteoporosis and periodontal disease. METHODS: The sample consisted of 139 postmenopausal women: 48 in the case group (with periodontal disease) and 91 in the control group (without periodontal disease). The diagnosis of periodontal disease was established following a complete clinical examination using measurements of probing depth, gingival recession and hyperplasia, clinical attachment loss, and bleeding index, and confirmed by panoramic radiography. The diagnosis of osteoporosis was made by reviewing densitometry reports obtained previously. Descriptive, stratified, and logistic regression analyses were applied to the data collected. Comparison of proportions was performed using the chi(2) and Fisher tests. Association measurements (odds ratios [ORs]) with and without adjustment for confounding factors and control for effect modifiers were obtained at a significance level of 5%. RESULTS: The OR(unadjusted) for the principal association was 2.58 (95% confidence interval [CI]: 1.01 to 6.82). In subgroup analyses of the stratified model, the OR(unadjusted) for low education was 6.40 (95% CI: 1.77 to 23.18). When adjusted for smoking habit and age, the OR(adjusted) was 7.05 (95% CI: 1.90 to 26.19), which also was statistically significant. CONCLUSION: Postmenopausal women with osteoporosis and low educational levels have a greater chance of having periodontal disease than do those without osteoporosis.
