Arsenic chronic exposure, particularly in its inorganic form, represents a significant public health concern. This study was conducted in Arica, the northernmost city in the country, whose inhabitants have been exposed to inorganic arsenic both naturally through drinking water and anthropogenically due to a toxic waste disposal site. We explored changes in inorganic arsenic levels in a cohort of pregnant women and their children over a decade, identifying exposure trends and their determinants. We used data on arsenic exposure through maternal urine samples during pregnancy, collected by the Health Authority between 2013 and 2016 (measurement 1), and followed up with assessments of their children in 2023 (measurement 2). Temporal changes in inorganic arsenic concentration were analyzed using the Wilcoxon Signed-Rank test, and a mixed linear regression model was employed to determine which factors contributed to urinary inorganic arsenic levels. We did not observe significant differences in mean arsenic concentrations between the two-time points (p = 0.4026). The mixed linear regression model revealed that children consuming bottled water had 8.3% lower urinary inorganic arsenic concentrations than those drinking tap water (95% CI: −15.36 to −0.54%). Additionally, children from ethnic groups had 8.64% higher inorganic arsenic concentrations (95% CI: 0.49 to 17.5%), while those with caregivers with higher education showed a 13.67% reduction (95% CI: −25.06 to −0.56%). Despite mitigation efforts, these findings underscore the ongoing risk of inorganic arsenic exposure among vulnerable populations. They further emphasize the importance of addressing natural arsenic contamination in water and implementing targeted interventions to reduce disparities associated with socioeconomic and demographic factors.</jats:p>

Exposure to visually appealing food items can enhance their subjective realism, leading to increased cravings, salivation, and automatic approach tendencies. Prior research suggests that brief mindfulness instructions promoting dereification—recognizing stimuli as transient mental events—can mitigate these automatic reactions. Objectives: This study assesses whether brief mindfulness instruction can mitigate automatic consumption tendencies induced by food advertisements, exploring the corresponding behavioral, physiological, and neurophysiological mechanisms. Methods: Sixty participants were randomly assigned to two groups: one receiving brief mindfulness instruction and the other a non-dereifying control instruction while exposed to advertised foods. This was followed by an approach–avoidance task (AAT), during which behavioral data, salivary volume, event-related potentials (ERPs) from electroencephalogram recordings, and self-reports were collected. Results: The results showed no significant differences in approach behaviors between the groups. Hunger, food craving, and salivation levels increased uniformly in response to food cues for both groups. The N1, N2, P3, and late positive potential (LPP) ERPs remained unaltered by the instructions and consistent with the established AAT literature. Advertising heightened the appeal of neutral foods, as evidenced by increased N2, P3, and LPP responses. Conclusions: The brief mindfulness instruction failed to shield participants from the automatic responses elicited by food advertising, contrasting with the effects seen with non-advertised food.

In Chile, the prevalence of overweight among schoolchildren over the age of 5 is approximately 50%, one of the highest in the Americas region. This is largely influenced by the presence of inadequate food environments, characterized by limited access to healthy foods and a high availability of highly processed foods (HPF). This study analyzes food consumption in Chilean schoolchildren and the association of this with the Chilean Dietary Guidelines Based on Foods (DGBF) and the HPF consumption.</jats:p> </jats:sec> <jats:sec id="sec002"> <jats:title>Material and methods</jats:title> <jats:p>The sample (1,094 schoolchildren) was obtained from the baseline of the FONDEF IT18I0016 project, in Santiago-Chile. Anthropometry and socioeconomic data were measured. Dietary intake was assessed using a validated semi-quantitative frequency survey featuring images of food groups aligned with DGBF, as well as HPF. All data were collected by trained professional nutritionists. Associations between dependent and independent variables, and potential confounding factors were calculated using logistic regression models with stepwise backward/forward. A p < 0.05 was accepted as significant, using Stata 16.0. <jats:p>Most of the students (54.1%) were with malnutrition by excess and 20.0% exhibited abdominal obesity. Twenty percent of the students met the recommended intake for DGBF (fruits, vegetables, fish, milk and dairy products, legumes, water) and less than 5% did not consume any HPF. Consuming some sub-groups of HPF in moderate quantities (either no consumption or occasional consumption) increases the likelihood of meeting DGBF: candies and sweets (OR: 0.72; p = 0.04), pies with or without filling (OR: 0.63; p = 0.01), and salted snacks (OR: 0.67; p = 0.02).</jats:p> Conclusion Our results contribute to reaffirm the need to enhance healthy food consumption among schoolchildren and to discourage the intake of HPF, particularly focusing on specific sub-groups of HPF that may increase the risk of displacing the consumption of food groups recommended by the DGBF.</jats:p>

<jats:p>Latin Americans have a rich genetic make-up that translates into heterogeneous fractions of the autosomal genome in runs of homozygosity (FROH) and heterogeneous types and proportions of indigenous American ancestry. While autozygosity has been linked to several human diseases, very little is known about the relationship between inbreeding, genetic ancestry, and cancer risk in Latin Americans. Chile has one of the highest incidences of gallbladder cancer (GBC) in the world, and we investigated the association between inbreeding, GBC, gallstone disease (GSD), and body mass index (BMI) in 4029 genetically admixed Chileans. We calculated individual FROH above 1.5 Mb and weighted polygenic risk scores for GSD, and applied multiple logistic regression to assess the association between homozygosity and GBC risk. We found that homozygosity was due to a heterogeneous mixture of genetic drift and consanguinity in the study population. Although we found no association between homozygosity and overall GBC risk, we detected interactions of FROH with sex, age, and genetic risk of GSD that affected GBC risk. Specifically, the increase in GBC risk per 1% FROH was 19% in men (p-value = 0.002), 30% in those under 60 years of age (p-value = 0.001), and 12% in those with a genetic risk of GSD above the median (p-value = 0.01). The present study highlighted the complex interplay between inbreeding, genetic ancestry, and genetic risk of GSD in the development of GBC. The applied methodology and our findings underscored the importance of considering the population-specific genetic architecture, along with sex- and age-specific effects, when investigating the genetic basis of complex traits in Latin Americans.</jats:p>

<jats:sec> <jats:title>Background:</jats:title> <jats:p>New generation devices that combine high-flow insufflation with smoke aspiration using continuous gas recirculation ]so-called Insufflator/aspirator systems (IAS)] have recently been developed to generate pneumoperitoneum. The use of an IAS could have an impact on surgical compared to conventional insufflation systems (CIS). The present study aimed to compare the clinical effectiveness/safety, healthorganizational, and pathological/oncological outcomes of the CIS versus IAS during robot-assisted radical prostatectomy (RARP).</jats:p> </jats:sec> <jats:sec> <jats:title>Methods:</jats:title> <jats:p>Comparative retrospective cohort study including patients with non-metastatic prostate cancer treated with RARP by four expert surgeons at a robotic referral centre between January 2020 and December 2021. A CIS was used until 15 March 2021, and the IAS thereafter. Data were extracted from the Institutional Review Board-approved (#1064) retro and prospective institutional database.</jats:p> </jats:sec> <jats:sec> <jats:title>Results:</jats:title> <jats:p>The final analysis included 299 patients (143 CIS; 156 IAS). We found no statistically significant differences in demographic data and preoperative results, allowing adequate group comparison. The rate of complications of any degree (9.1% and 1.9%, <jats:italic toggle="yes">P</jats:italic><0.05) and major complications (4.2% and 0.6%, <jats:italic toggle="yes">P</jats:italic><0.05) were lower in the IAS group. Accordingly, the hospital stay was shorter in the IAS group (<jats:italic toggle="yes">P</jats:italic><0.05); however, the small size of this statistically significant difference probably lacks clinical value (1.9±1.6 vs. 1.6±0.8 days). There was no significant difference in surgical time, bleeding, pathological findings, or oncological results.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions:</jats:title> <jats:p>Data from this large group of patients showed that the rate of overall complications, the rate of major complications, and the length of stay were lower in the IAS group. Implementing the IAS in RARP patients increased the occurrence of SCE and affected our daily practice of transversus abdominis plane block. Interpretation of the results should be made with caution since the design of this study did not allow for the identification of a causal relationship.</jats:p> </jats:sec>

Dietary Advanced Glycation End Products: Their Role in the Insulin Resistance of Aging
(2023)

<jats:p>Insulin resistance (IR) is commonly observed during aging and is at the root of many of the chronic nontransmissible diseases experienced as people grow older. Many factors may play a role in causing IR, but diet is undoubtedly an important one. Whether it is total caloric intake or specific components of the diet, the factors responsible remain to be confirmed. Of the many dietary influences that may play a role in aging-related decreased insulin sensitivity, advanced glycation end products (AGEs) appear particularly important. Herein, we have reviewed in detail in vitro, animal, and human evidence linking dietary AGEs contributing to the bodily burden of AGEs with the development of IR. We conclude that numerous small clinical trials assessing the effect of dietary AGE intake in combination with strong evidence in many animal studies strongly suggest that reducing dietary AGE intake is associated with improved IR in a variety of disease conditions. Reducing AGE content of common foods by simple changes in culinary techniques is a feasible, safe, and easily applicable intervention in both health and disease. Large-scale clinical trials are still needed to provide broader evidence for the deleterious role of dietary AGEs in chronic disease.</jats:p>
