RESUMO

Aluminum (Al) may be beneficial to crops, but in excess becomes detrimental to the germination and initial development of seedlings. The main determining indicators are the type of crop and exposure duration. The aim of this study was to examine the influence of Al and of UV-C light on the germination and initial growth of white oats. Seeds were sown on germitest paper in a solution of 100, 200, 300, 400, or 500 mg/L of aluminum chloride and kept in a germination chamber at 20°C for a 12-hr photoperiod. Germination and seedling growth parameters were determined after 5 and 10 days. The seeds were also exposed to two doses of UV-C (0.85 and 3.42 kJ m-2) under aluminum chloride stress (200 mg/L). Data demonstrated that treatment with aluminum chloride significantly decrease in germination at 200 mg/L and total seedling length at 100 mg/L. Exposure of seeds to UV-C light under excess Al (200 mg/L) did not show a significant effect on germination and growth compared to control (non-irradiated). Results indicated that exposure to high concentration of Al in the medium adversely altered germination and initial growth of white oat seedlings. Although UV-C light alone was not detrimental to the germination process, treatment with UV-C light also failed to mitigate the toxic effects of Al.

RESUMO

Reports of excess mortality during the COVID-19 pandemic in Argentina have been partial and fragmented so far. This study aimed to quantify excess deaths and explore their demographic, temporal, and geographic distribution during the period 2020-2022. Using data from 1 192 963 death records from vital statistics and population projections, expected mortality was estimated using regression models. Excess death was calculated as the difference between observed and expected mortality. An excess of 160 676 deaths (95% CI 146 861 to 174 491) was estimated, representing a rate of 116.9 (95% CI 115.5 to 118.3) additional deaths per 100 000 personyears. Significant heterogeneity was found among the different argentine provinces. The results indicate an uneven impact of the pandemic, with higher excess mortality rates in some regions and more vulnerable age groups. These patterns suggest the need for differentiated strategies of healthcare response and support to the most vulnerable populations in scenarios of new epidemics.

RESUMO

The aim of this work was to stabilize excess sludge (ES) coming from a wastewater treatment plant (WWTP) by vermistabilization and to evaluate ecotoxicological effects over the earthworm species Eisenia fetida. Three mixtures were made up in triplicate using different volume ratios of ES and soil (S) (100% ES, 70:30% ES:S and 30:70% ES:S in wet weight basis). Earthworms were added in order to compare vermicomposting vs. natural stabilization. The mixtures were monitored over 130 days through physical, chemical, pathological and biological analysis, following quality standards depicted in the US EPA 40 CFR Part 503, local regulations and background studies. Histopathological samples were processed as biomarkers of acute and chronic toxicity on earthworms, and germination assays were performed at the end of the experiment to assess phytotoxicity. In terms of pathogen depletion comparing initial and final values from each treatment, the mixtures with higher ES proportions (70 and 100%) with earthworms were the most efficient ones registering 64.8 and 75.5% of reduction of fecal coliforms (FC) respectively, while the lowest ES proportion with earthworms (30%) showed 54.7%. Final pathogens content in all the treatments with earthworms were significantly lower (ranged from 1360 to 1760 MPN g total solids-1) than the values registered in treatments without earthworms (ranged from 2400 to 4000 MPN g total solids-1) (p < 0.05). However, none of the treatments attained class A categorization (FC ≤ 1000 MPN g total solids-1) in terms of FC. Also, values of mean cocoon production and hatched juveniles along time were significantly higher in the treatments with 100 and 70% ES (p < 0.05), while the higher mean adult biomass was detected in the treatment with 30% ES. Volatile solids decrease ranged between 8.45 and 22.34% in treatments with earthworms and all values of specific oxygen uptake rate were below 1.5 mg O2 h -1 g total solids -1. There were not negative effects over behavior or reproduction of E. fetida adults, nor the presence of external and internal injuries. Final products from mixtures with earthworms presented a humus-like structure, were odorless and reached maturity values -presenting no phytotoxicity-with significant differences between germination index values of treatments with and without earthworms (p < 0.05). Vermistabilization is a successful eco-technology to sanitize excess sludge, acquiring an added-value material and contributing to its revalorization as organic amendments or fertilizers in soils within the circular economy framework and the United Nations' Sustainability Development Goals.

RESUMO

PURPOSE: This study aimed to investigate the association between social jetlag (SJL) and obesity-related outcomes among adolescents from Valle de Ricote (Region of Murcia, Spain). We explored the relationship between SJL and body mass index (BMI) z-score, waist circumference, and body fat percentage, as well as the odds of having excess weight, obesity, and abdominal obesity in a sample of Spanish adolescents. METHODS: A cross-sectional study was conducted using data from the Eating Healthy and Daily Life Activities (EHDLA) project, which included 847 Spanish adolescents aged 12-17 years. SJL was assessed based on the differences in sleep patterns between weekdays and weekends. Obesity-related indicators such as BMI z-score, waist circumference, body fat percentage, excess weight, obesity, and abdominal obesity were measured. Generalized linear models with a Gaussian or binomial distribution were used to analyze the associations between SJL and obesity-related outcomes, adjusting for potential confounders. RESULTS: The analysis revealed significant associations between SJL and BMI z-score (unstandardized beta coefficient [B] = 0.15, 95% CI: 0.05 to 0.25, p = 0.003), waist circumference (B = 1.03, 95% CI: 0.39 to 1.67, p = 0.002), and body fat percentage (B = 0.83, 95% CI: 0.31 to 1.43, p = 0.008). Additionally, the odds ratios (ORs) for excess weight (OR = 1.35, 95% CI: 1.16 to 1.57; p < 0.001), obesity (OR = 1.59, 95% CI: 1.26 to 2.00; p < 0.001), and abdominal obesity (OR = 1.46, 95% CI: 1.23 to 1.72; p < 0.001) increased significantly with each 60 min increment in SJL. CONCLUSIONS: This study pointed out that the misalignment of sleeping times during weekdays and weekends (SJL) is significantly associated with higher BMI z-scores, waist circumference, body fat percentage, and higher odds of excess weight, obesity, and abdominal obesity among adolescents, being more significant in boys than in girls. These findings highlight the importance of addressing circadian misalignment in the prevention and management of obesity and its related metabolic disorders in this population.

RESUMO

BACKGROUND: Tools for assessing a country's capacity in the face of public health emergencies must be reviewed, as they were not predictive of the COVID-19 pandemic. Social cohesion and risk communication, which are related to trust in government and trust in others, may have influenced adherence to government measures and mortality rates due to COVID-19. OBJECTIVE: To analyse the association between indicators of social cohesion and risk communication and COVID-19 outcomes in 213 countries. RESULTS: Social cohesion and risk communication, in their dimensions (public trust in politicians, trust in others, social safety nets, and equal distribution of resources index), were associated with lower excess mortality due to COVID-19. The number of COVID-19-related disorder events and government transparency were associated with higher excess mortality due to COVID-19. The lower the percentage of unemployed people, the higher the excess mortality due to COVID-19. Most of the social cohesion and risk communication variables were associated with better vaccination indicators, except for social capital and engaged society, which had no statistically significant association. The greater the gender equality, the better the vaccination indicators, such as the number of people who received all doses. CONCLUSION: Public trust in politicians, trust in others, equal distribution of resources and government that cares about the most vulnerable, starting with the implementation of programs, such as cash transfers and combating food insecurity, were factors that reduced the excess mortality due to COVID-19. Countries, especially those with limited resources and marked by social, economic, and health inequalities, must invest in strengthening social cohesion and risk communication, which are robust strategies to better cope with future pandemics.

RESUMO

PURPOSE: The use of a nonadjustable silicone band around the gastric pouch of Roux-en-Y gastric bypass (RYGB) to reduce the recurrence of obesity is still being debated in the literature. The primary objective of this study was to evaluate banded and non-banded RYGB regarding % total weight loss (%TWL) and complications up to 10 years postoperatively and regarding the removal rate of the silicone band. MATERIAL AND METHODS: A retrospective study of the medical records of all patients submitted to banded and non-banded RYGB between 2000 and 2020 was conducted. Clinical data (age, gender, weight, body mass index-BMI, comorbidities, %TWL, and the prevalence of vomiting) and laboratory data (hemoglobin, serum iron, albumin, and vitamin B12) were obtained preoperatively and at 6 months, 1, 2, 3, 5, 7, and 10 years for both groups and at 12, 15, and 20 years after banded RYGB. RESULTS: In total, 858 patients underwent RYGB: 409 underwent banded RYGB and 449 underwent non-banded RYGB. In the preoperative period, banded RYGB patients were heavier and had higher rates of hypertension and dyslipidemia. The %TWL was higher in the banded RYGB group up to 7 years. The prevalence of vomiting is much higher in this group, which also had lower laboratory test values. Of the banded RYGB patients, 9.53% had to have the silicone ring removed after presenting complications. CONCLUSION: Banded RYGB promotes significantly higher rates of TWL at the expense of a higher frequency of food intolerance and vomiting.

RESUMO

(1) Background: An elevated wrist circumference may indicate excess weight and cardiometabolic risk. The present study aims to identify wrist circumference cutoff points (WrC) to determine excess weight levels and predict cardiometabolic risk in adults. (2) Methods: A cross-sectional study was conducted with adults aged 20 to 59 years old, attending the outpatient clinic at University Hospital/Federal University of Sergipe HU/UFS-EBSERH. Demographic, anthropometric, biochemical, and blood pressure (BP) data were collected. Cardiometabolic risk was assessed, according to the global risk score (ERG) and Framingham score criteria. The descriptive analysis included calculating medians and frequencies of anthropometric, demographic, biochemical, and blood pressure variables. The gender and age of adult groups were compared using the Mann-Whitney test. Spearman's correlation coefficient and multiple regression analysis were used to assess the association between wrist circumference (WrC) and the variables mentioned above. The predictive validity of WrC in identifying excess weight levels and cardiometabolic risk was analyzed using the ROC curve. The sample consisted of 1487 adults aged 20 to 59 years, 55.7% of whom were female; (3) Results: WrC correlated positively with other adiposity indicators such as waist circumference and Body Mass Index. WrC was the anthropometric indicator most significantly associated with cardiometabolic risk factors. WrC cutoff points identified by the study for determining excess weight were categorized by gender and age group. For males aged 20 to 40 years and >40 years, respectively, the cutoff points for overweight were 17.1 cm and 17.3 cm, and for obesity, 17.9 cm and 17.5 cm. For females aged 20 to 40 years and >40 years, respectively, the cutoff points for overweight were 15.6 cm and 15.4 cm, and for obesity, 16.1 cm and 16 cm (4). Conclusions: Wrist circumference showed a significant correlation with other adiposity indicators and can be used to identify adults with excess weight and predict cardiometabolic risk.

RESUMO

Background: The COVID-19 pandemic has proved deadly all over the globe; however, one of the most lethal outbreaks occurred in Ecuador. Aims: This study aims to highlight the pandemic's impact on the most affected countries worldwide in terms of excess deaths per capita and per day. Methods: An ecological study of all-cause mortality recorded in Ecuador was performed. To calculate the excess deaths relative to the historical average for the same dates in 2017, 2018, and 2019, we developed a bootstrap method based on the central tendency measure of mean. A Poisson fitting analysis was used to identify trends on officially recorded all-cause deaths and COVID-19 deaths. A bootstrapping technique was used to emulate the sampling distribution of our expected deaths estimator µâŒ¢deaths by simulating the data generation and model fitting processes daily since the first confirmed case. Results: In Ecuador, during 2020, 115,070 deaths were reported and 42,453 were cataloged as excess mortality when compared to 2017-2019 period. Ecuador is the country with the highest recorded excess mortality in the world within the shortest timespan. In one single day, Ecuador recorded 1,120 deaths (6/100,000), which represents an additional 408% of the expected fatalities. Conclusion: Adjusting for population size and time, the hardest-hit country due to the COVID-19 pandemic was Ecuador. The mortality excess rate shows that the SARS-CoV-2 virus spread rapidly in Ecuador, especially in the coastal region. Our results and the proposed new methodology could help to address the real situation of the number of deaths during the initial phase of pandemics.

RESUMO

BACKGROUND: Evidence from Latin America suggests that children embedded in South-to-North migrant networks (i.e. relatives who live abroad, typically in the United States) are at increased risk of excess weight. It is unclear if the same findings apply to children embedded in Latin American intraregional migration or South-to-South migration networks. OBJECTIVE: To compare excess weight among Colombian children embedded in South-to-South migration networks (n = 334) to children with non-migrant parents (n = 4272) using Colombia's 2015 National Survey of the Nutritional Situation. METHODS: Prevalence ratios (PRs) for excess weight (BMI z-score ≥1) by parent migration history were estimated using weighted multivariable logistic regression adjusting for demographics, child behaviours, community and household indicators, including household food insecurity. RESULTS: Most migrant parents returned to Colombia from Venezuela (84%) and reported higher household food insecurity rates than non-migrant parents (59% versus 32%). Models excluding household food insecurity showed that excess weight among children with migrant parents was 51% lower (PR = 0.49; 95% CI 0.25, 0.98) than among children with non-migrant parents. After adjustment for household food insecurity, no statistically significant differences were found. CONCLUSION: Colombian children with return migrant parents from Venezuela experienced less excess weight than children with non-migrant parents, but higher rates of food insecurity in migrant households might partially explain this difference. This study calls attention to two serious public health concerns for Colombian children-those who have excess weight and those who lack sufficient food, particularly among migrant returnees (a situation that may have worsened since the COVID-19 pandemic).

RESUMO

PURPOSE: Previous literature has demonstrated the mediating role of adiposity in the association between cardiorespiratory fitness (CRF) and cardiometabolic risk as well as the potential role of CRF in attenuating the adverse consequences associated with excess weight. This study aimed to evaluate the mediating role of CRF and adiposity in the possible association with cardiometabolic risk. METHOD: Observational 3-year longitudinal study that included 420 children and adolescents (10.50 [2.05] y of age at baseline; 56.2% girls). Body mass index (BMI) was calculated, and CRF was evaluated using field assessments. A clustered cardiometabolic risk score (cMetS) was calculated from glucose, systolic blood pressure, total cholesterol/high-density lipoprotein cholesterol ratio, and triglycerides z scores. Analyses evaluated the mediating role of BMI in the association between CRF and cMetS as well as whether CRF mediated the association between BMI and cMetS. RESULTS: BMI at baseline was directly associated with the cMetS at follow-up (0.102; 95% confidence interval, 0.020 to 0.181), independently of CRF, whereas CRF was only indirectly associated with cMetS at follow-up through BMI (-0.036; 95% confidence interval, -0.070 to -0.009), meaning that the association between CRF and cMetS was explained via the mediation role of BMI. CONCLUSIONS: BMI presented direct association with cMetS, whereas CRF exhibited indirect association with cMetS mediated via BMI.

RESUMO

The coexistence of stunting and excess weight in the same individual is defined as a double burden of malnutrition (DBM) and is associated with noncommunicable diseases. In this study, we evaluated the impact of DBM on adipokine concentrations and metabolic profiles in children compared with weight excess alone. Children were allocated to the weight excess group (n = 23) (height-for-age (HAZ) > 0.0 and < 2.0 Z-score and body mass index-for-age (BMI/A) > 1.0 Z-score) or DBM (n = 22) group (HAZ < -1.0 Z-score (including mild stunting) and BMI/A > 1.0 Z-score). Lipid, glycemic profile, resistin, plasminogen activator inhibitor-1, leptin, and adiponectin concentrations were analyzed. Glycemia was significantly higher in the DBM group compared to the weight excess group (5.05 (4.76-5.31) mmol/L vs. 4.57 (4.35-4.81) mmol/L), although no differences were found in insulin and homeostasis model assessment of insulin resistance (HOMA-IR). Adipokine concentrations did not differ between the groups. However, the DBM group showed higher resistin concentrations normalized by body fat mass than those of the weight excess group (1.44 (0.98-1.93) ng/mL vs. 0.76 (0.55-1.45) ng/mL). Insulin and HOMA-IR showed a negative correlation with adiponectin (r = -0.590 and -0.624, respectively, both p < 0.01). DBM was associated with increased glucose and resistin concentrations adjusted by fat mass compared to that associated with excess weight alone. Therefore, this association between mild stunting and weight excess has deleterious potential for long-term metabolic function, highlighting an additional precaution against weight gain in children, especially in those with stunting.

RESUMO

BACKGROUND: Because COVID-19 has been associated with high lethality rates among kidney transplant recipients (KTR), but also with a severe disruption and delays in overall healthcare, this study aims to evaluate the excess mortality in the pandemic era among KTR in a high-volume Brazilian transplant center. METHODS: This study used data from a single center that provides follow-up on all its transplant recipients. The population of interest included all the patients who were transplanted between August 31, 1983 and December 31, 2022 and who were live from January 1, 2014. Using the "AutoRegressive Integrated Moving Average" forecasting algorithm, the expected mortality for the pandemic era (2020-2022) was modeled from the pre-pandemic era (2014-2019). RESULTS: There were 12 077 KTRs at risk of dying in the entire observation period. In the pre-pandemic era, there were 21 deaths per 1000 patients at risk. In the pandemic era, there were 1429 observed deaths (rate of 47 deaths per 1000 patients at risk) versus the expected 587 deaths, resulting in an absolute number of 842 excess deaths, or an observed-to-expected ratio of 2.4, or an absolute rate of 26 deaths in excess per 1000 patients at risk. The excess deaths exhibited a temporal pattern mirroring that of the surges in new cases and lethality rates of COVID-19. COVID-19-related deaths drove 94% of excess mortality in the pandemic era. CONCLUSION: In this large cohort of KTR under centralized follow-up, more than twofold excess mortality was primarily driven by COVID-19-related deaths, highlighting the vulnerability of this population to the most severe presentation of SARS-CoV-2 infection.

RESUMO

Abstract: We evaluated the hypothesis of an association between excess mortality and political partisanship in Brazil using municipal death certificates registered in the Brazilian Ministry of Health database and first-round electoral results of Presidential elections in 2018 and 2022. Considering the former Brazilian President's stance of discrediting and neglecting the severity of the pandemic, we expect a possible relationship between excessive mortality rates during the COVID-19 health crisis and the number of municipal votes for Bolsonaro. Our results showed that, in both elections, the first-round percentage of municipal votes for Bolsonaro was positively associated with the peaks of excess deaths across Brazilian municipalities in 2020 and 2021. Despite the excess mortality during the pandemic, the political loyalty to Bolsonaro remained the same during the electoral period of 2022. A possible explanation for this is linked to the Brazilian political scenario, which presents an environment of tribal politics and affective polarization.

Resumo: Usando dados municipais em declarações de óbito registrados no Ministério da Saúde e resultados eleitorais do primeiro turno das eleições presidenciais de 2018 e 2022, avaliamos a hipótese de que há associação entre excesso de mortalidade e partidarismo político no Brasil. Dada a postura do ex-presidente brasileiro de desacreditar e negligenciar a gravidade da pandemia, esperamos que haja possivelmente uma relação entre as taxas excessivas de mortalidade durante a crise sanitária da COVID-19 e o número de votos municipais para Bolsonaro. Nossos resultados mostraram que, em ambas as eleições, o percentual de votos municipais no primeiro turno para Bolsonaro foi positivamente associado aos picos de excesso de mortes nos municípios brasileiros em 2020 e 2021. Mesmo com o excesso de mortalidade durante a pandemia, a lealdade política de Bolsonaro não diminuiu durante o segundo período eleitoral em 2022. Uma possível explicação para isso está ligada ao cenário político brasileiro, que vive um ambiente de política tribal e polarização afetiva.

Resumen: A partir de datos municipales sobre certificados de defunción registrados en el Ministerio de Salud de Brasil y de los resultados electorales de la primera vuelta de las elecciones presidenciales de 2018 y 2022, se evaluó si existe una asociación entre el exceso de mortalidad y el partidismo político en Brasil. Ante la postura del ex presidente brasileño de desacreditar y desatender la gravedad de la pandemia, probablemente exista una relación entre las altas tasas de mortalidad durante la crisis de salud del COVID-19 y el número de votos municipales para Bolsonaro. Los resultados demostraron que, en ambas elecciones, el porcentaje de votos municipales en la primera vuelta para Bolsonaro estuvo asociado positivamente con los picos de alta de muertes en los municipios brasileños para el período 2020-2021. Incluso con la alta mortalidad durante la pandemia, la lealtad política de Bolsonaro no disminuyó durante el segundo período electoral en 2022. Una de las posibles explicaciones es que esto se vincula al escenario político brasileño, que vive una política tribal y polarización afectiva.

RESUMO

ABSTRACT Objective To investigate excess mortality during the COVID-19 pandemic and its spatial distribution in Pernambuco, Brazil. Methods This was an ecological, descriptive and analytical study of deaths, by municipality, recorded on the Mortality Information System, in 2020 and 2021. Excess mortality was measured by comparing observed and expected deaths, the latter estimated by calculating standardized mortality ratio (SMR). SMR and respective confidence intervals (95%CI) were calculated. Spatial analysis was performed by calculating the Global and Local Moran Index. Results Excess mortality was 20.6% and 27.5%, respectively, in 2020 and 2021, with positive spatial correlation (p-value < 0.05). More populous municipalities (2020: SMR = 1.26; 95%CI 1.24;1.27 and 2021: SMR = 1.34; 95%CI 1.32;1.34), more developed municipalities (2020: SMR = 1.43; 95%CI 1.41;1.44 and 2021: SMR = 1.51;95%CI 1.50;1.53) and municipalities in the Sertão region (2020:SMR = 1.31;95%CI 1.30;1.33 and 2021: SMR = 1.44; 95%CI 1.42;1.46) showed greater excess deaths. Conclusion Excess mortality coincided with peak periods of COVID-19 transmission.

Conclusão O excesso de mortalidade coincidiu com os períodos de pico de transmissão da covid-19.

RESUMO

Abstract Objectives: to describe the effects of the Covid-19 pandemic on maternal mortality in Brazil in 2021. Methods: it is an exploratory study with description of the excess maternal mortality in Brazil for 2021, considering different scenarios: (i) 2015-2019 linear trend; (ii) 2020 observed number of deaths; (iii) 2015-2019 linear trend corrected for general mortality excess; (iv) 2020 observed number of deaths corrected for general mortality excess. Results: compared to the trend of the previous five years, the year 2021 showed an excess mortality of 39% (n=3030). The maternal mortality ratio for 2021 drastically exceeded the SDG target for this indicator, reaching approximately 110 maternal deaths per 100,000 live births. In any scenario described, there will be excess maternal mortality in 2021 higher than general mortality and higher than level presented in 2020. Analysis stratified by region demonstrates subnational heterogeneity. Conclusion: Covid-19 pandemic had a considerable impact on maternal health, not only by leading to increased deaths but also by increasing social health inequality. The year 2021 was the most critical period of the pandemic regarding the magnitude of mortality. Barriers to accessing and using essential health services are challenging to achieving health-related Sustainable Development Goals.

Resumo Objetivos: analisar os efeitos da pandemia da Covid-19 na mortalidade materna no Brasil em 2021. Métodos: realizou-se estudo exploratório com descrição do excesso de mortalidade materna no Brasil para 2021, considerando diferentes cenários: (i) tendência linear 2015-2019; (ii) número de óbitos observados em 2020; (iii) tendência linear 2015-2019 corrigida para excesso de mortalidade geral; (iv) número de óbitos observados em 2020 corrigido pelo excesso de mortalidade geral. Resultados: em comparação com a tendência dos cinco anos anteriores, o ano de 2021 apresentou excesso de mortalidade de 39% (n=3030). A razãode mortalidade materna para 2021 ultrapassou a meta dos ODS para este indicador, atingindo um nível superior a 110 mortes maternas por cem mil nascidos vivos. Em qualquer cenário, houve excesso de mortalidade materna em 2021 superior à mortalidade geral em 2020. A análise estratificada por região demonstra heterogeneidade subnacional. Conclusão: a pandemia da Covid-19 teve impacto considerável na saúde materna, não só por levar ao aumento de mortes, mas também por aumentar a iniquidade em saúde. O ano de 2021 foi o período mais crítico da pandemia em termos de mortalidade. Barreiras ao acesso e uso de serviços de saúde são um desafio para alcançar os Objetivos de Desenvolvimento Sustentável relacionados à saúde.

RESUMO

RESUMEN Objetivo: Estimar y comparar la frecuencia de caries en niños de 6 a 11 años con malnutrición por exceso y normopeso que fueron atendidos en la clínica de odontopediatría de la Universidad Andrés Bello (Santiago, Chile) en 2021 y 2022. La hipótesis es que la frecuencia de caries dental en niños con malnutrición por exceso es mayor que en niños normopeso. Materiales y métodos: Diseño: Exploratorio, descriptivo y transversal. Se escogieron 52 pacientes normopeso que cumplían con los criterios de inclusión (28 y 24 niños de 6 a 8 años y de 9 a 11 años, respectivamente) y 44 malnutridos por exceso (29 y 15 niños 6 a 8 años y 9 a 11 años, respectivamente), tomando en consideración el control de los factores confundentes o factores no controlados: nivel socioeconómico, dieta, higiene y enfermedades que condicionen la salud bucal. Mediciones: Estimación de medias de frecuencia de caries, desviación estándar e intervalo de confianza 95 %. Resultados: Se observa que las medias de las frecuencias de caries en los niños normopeso son menores que los niños malnutridos por exceso en todos los grupos de edades estudiados. Conclusión: Se infiere que los niños con mala nutrición por exceso se relacionan con valores altos de frecuencia de caries.

ABSTRACT Objective: To estimate and compare the frequency of caries in children aged 6 to 11 years with malnutrition due to excess and normal weight who were treated at the Odontological Clinic of Pediatric Dentistry at the Andrés Bello University (Santiago, Chile) in the years 2021 and 2022. The hypothesis is that the frequency of dental caries in children with excess malnutrition is higher than in normal weight children. Materials and methods: Desing: exploratory, descriptive and cross-sectional. 52 normal weight patients (28 and 24 children aged 6 to 8 and 9 to 11 years respectively) and 44 malnourished due to excess (29 and 15 children aged 6 to 8 and 9 to 11 years respectively) were chosen, taking into consideration the control of confounding factors: socioeconomic level, diet, hygiene and diseases that condition oral health. Measurements: to estimate of the frequency of caries, standard deviation and confidence interval. Results: It is observed that the mean caries frequencies in children with normal weight are lower than those in children malnourished due to excess. Conclusion: It is inferred that children with poor nutrition due to excess are related to high caries frequency values.

RESUMO

Background/Objective: Guidelines on obesity management reinforce regular exercise to reduce body fat. Exercise modalities, including high-intensity interval training (HIIT), appear to produce a similar effect to continuous aerobic training (CAT) on body fat. However, they have not addressed the chronic effect of HIIT vs. CAT on body fat assessed by dual energy X-ray absorptiometry (DEXA). Thus, we compared the effectiveness of CAT vs. HIIT protocols on body fat (absolute or relative) (%BF) and abdominal visceral fat reduction, assessed by DEXA, in adults with overweight and obesity. Methods: We conducted a systematic review and meta-analysis of randomized clinical trials (RCTs) including both female or male adults with excess body weight. We performed searches in the databases MEDLINE (PubMed), EMBASE, Scopus, LILACS, Web of Science and Cochrane. Results: In our analysis (11 RCTs), we found no greater benefit on %BF of HIIT vs. CAT (MD -0.55%, 95% CI -1.42 to 0.31; p = 0.209). As for abdominal visceral fat, no training modality was superior (SMD: -0.05, 95% CI -0.29 to 0.19; p = 0.997). Regarding secondary outcomes (body weight, BMI, VO2 max, glycemic and lipid profiles), HIIT shows greater benefit than CAT in increasing VO2 max and fasting blood glucose and reducing total cholesterol. Conclusion: HIIT is not superior to CAT in reducing %BF or abdominal visceral fat in individuals characterized by excess weight. However, HIIT showed beneficial effects on cardiorespiratory fitness, total cholesterol and fasting blood glucose when compared to CAT.
