As the first step toward implementing strategies to improve mobility in urban centers, governmental authorities must assess their present situation in order to identify the most effective actions that should be included in their short and long-term plans. However, there is not a well-established methodology to carry out such an assessment. The already existing ones are subjective, incomplete, costly, and hard to implement, especially for the case of Latin American (LATAM) countries. This paper proposes a comprehensive methodology to carry out this assessment. It uses recent advances in information technologies and includes the use of web map services, telematics data, and low-cost vehicle emission tests. As an example of application, a mobility assessment was carried out for Saltillo, a medium-sized city in northeastern Mexico, which is considered a typical city in LATAM countries. Results indicate that this methodology can be replicated at a low incremental cost and that it leads towards the identification of the most sustainable (economic, environmental, and social) actions that should be implemented in these cities considering their local circumstances.

Abstract Background More than 20% of the children around the world were stunted in 2018. The situation is not any better in Latin American countries, even though stunting prevalence has been declining since 2000. Stunting has adverse consequences on children: severe short- and long-term health and functional effects, poor cognition and educational performance, low adult wages, and productivity loss. Methods This study compares maternal education gradients in height-for-age z-scores (HAZs) and stunting prevalence in children between two and four years of age from eight different Latin American countries: Chile, Uruguay, Costa Rica, Paraguay, Mexico, El Salvador, Nicaragua, and Peru. Results Results show that the prevalence of stunting varies widely across Latin American countries. Having a mother with tertiary education increases HAZs in every country (except Paraguay), compared to having a mother with primary education or less. In some countries, there is also a difference in HAZs associated with secondary versus primary maternal education. With regard to stunting, maternal education is a crucial determinant to decrease the odds of being stunted in early years in countries with the highest stunting prevalence (≈ 20%); however, this is not the case for countries where the prevalence is low (< 5%). Conclusions We found that maternal education is associated with height and stunting in preschool-aged children in our sampled Latin American countries. The association’s magnitude is higher for LMICs than for countries with a higher income per capita in the zone (i.e., Chile and Uruguay). These results suggest that future policies aiming to increase maternal education will improve children’s height-for-age and decrease their risk of stunting.

Objective: Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. Methods: From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue - mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. Results: There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT - with follow-ups averaging two years (0.5-8) - are receiving thyroxin substitution. Conclusions: There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.
