RESUMO

Liza María González-HernándezPatients with breast cancer undergoing conservative surgery require management with radiotherapy to decrease the risk of recurrence. Moreover, the use of tumor bed boost in high-risk patients has shown an absolute reduction in the 10-year local recurrence risk from 23.9 to 13.5%. Therefore, this study aimed to estimate the overall survival of a group of patients undergoing conservative surgery with a boost through interstitial brachytherapy at a cancer center in Medellin, Colombia. A retrospective cohort study was performed, and records from 2014 to 2020 of patients with in situ or infiltrating breast cancer treated with a boost through interstitial brachytherapy were included. Univariate analysis was conducted to characterize the study population; median survival was calculated using the Kaplan-Meier method. Moreover, associations concerning survival were calculated with each of the factors independently. A total of 186 patients were included. Their overall survival was 93.5%, with a median survival of 79 months. The presence of negative hormone receptors, having two or more irradiated fields and having a locally advanced stage were factors associated independently with higher mortality. The overall survival of patients with in situ or infiltrating breast cancer was favorable and correlated with studies regarding intervention with a boost through interstitial brachytherapy and the factors associated with higher mortality, such as having a locally advanced stage.

RESUMO

OBJECTIVE: To describe the characteristics of the labor induction process associated with the excess number of cesarean sections in women subjected to this intervention. METHODS: Descriptive historical. cohort that included pregnant women without a history of previous cesarean section, with single term pregnancy and cephalic presentation who were subjected to labor induction in a Level III com- plexity hospital in Medellín, Colombia, during the time period between May 2015 and October 2016. Consecutive sampling was used. Measured variables were maternal age, parity, gestational age, indica- tion for labor induction, cervical favorability, time of induction, quality of uterine activity achieved, type of delivery, and time point during induction when the decision of cesarean section was made. The clinical practice guidelines of international organizations of the specialty and the new guides arising from the 2012 proposal of limiting the first cesarean section were used in order to define ad- herence to the recommendations for induction. RESULTS: Of the 2402 births, 289 which met the inclusion criteria were selected. Cesarean section was performed in 48% of the women subjected to induction, 60.8% nulliparous and 32.1% multiparous. Of those with unfavorable cervix, 72.2% received oxytocin for cervical maturation. Of the women subjected to delivery induction, 108 (37%) underwent cesarean section due to a diagnosis of failed induction. This was considered inadequate in all of them, considering that the diagnosis was made before reaching a dilatation of 6 cm in 88 (81.5%), with intact membranes in 67 (62%), with no uterine activity in 42 (38.9%), with poor quality uterine activity in 23 (21.3%) and in 55 (61%) who did not have at least 24 hours of latent phase before undergoing cesarean section. CONCLUSIONS: Failure to adhere to the recommendations for adequate induction was found, added to a mistaken diagnosis of failed induction.

RESUMO

BACKGROUND: Meals served at government-run day care centers must be nutritionally adequate to ensure good health and proper development of preschool-aged children. They can provide a controlled opportunity to complement the daily diet of children in vulnerable populations. OBJECTIVE: To determine the nutrient adequacy and leading food sources of nutrients provided by the diet served in government-sponsored day care centers. METHODS: Estimated daily energy and nutrient intakes of a theoretical 40-day day care center menu were calculated, and the nutrient adequacy was assessed. Nutrient densities and critical nutrient densities of the menu were computed to identify nutrient inadequacies. Furthermore, main sources of nutrients were identified, and energy and nutrient distributions were examined by meal time. RESULTS: The menu provides approximately 90% of daily energy requirement and more than 100% of Recommended Nutrient Intakes (RNIs), with the exception of vitamin D and calcium. Sugar was the first leading source of energy, whereas milk was the first leading contributor of vitamin D. CONCLUSION: Within an environment of budgetary constraints, the Guatemalan government developed and advocated an exemplary menu offering for children in the vulnerable preschool period. We have demonstrated that, if prepared and served as planned, the items from the official, standard menu would supply most of the nutrients needed. High vitamin A intake related to the mandated national fortification program is a potential problem. From the analysis, it was found that vitamin D emerges as the most prominent candidate for a problem nutrient of deficient intake.

RESUMO

Complementary foods (CF) are introduced earlier or later than appropriate in developing societies. They often contribute poorly to overall adequate micronutrient intake during the critical period for growth and development, which constitutes the period from 6 to 12 months of life. The objective of this study was to determine the contribution of the CF nutrients to the total estimated nutrient intake in infants in the second semester of life. Three non-consecutive 24-hour recalls interviews were conducted with mothers of 64 infants, aged 6-12 months on enrolment, from a convenience sample in a marginal urban settlement in Guatemala City. Retrospective recording of early introduction of pre- and post-lacteal feeding and introduction of first foods and beverages was included. Human milk intakes were estimated by a model based on assumptions that human milk plus CF exactly satisfied the infant's daily energy needs. The WHO/FAO Recommended Nutrient Intakes (RNI) were the standards for adequate nutrient consumption. Instances of exclusive breast feeding to 6 months were rare, with the introduction of CF earlier than recommended. Baby food in jars was mentioned most frequently as the first food offered. The contribution of CF increased with age through the second semester of life. CF contributed more of a nutrient than human milk in all instances. However,CF nutrient density for Ca, Fe, and Zn fell below international standard. Fortified sugar contributed excessive amounts of Vitamin A to the diets. We conclude that for most nutrients, intakes reached or exceeded recommendation levels, unusual within the CF experience in scientific literature.

RESUMO

OBJECTIVE: To compare variety and diversity patterns and dietary characteristics in Guatemalan women. MATERIAL AND METHODS: Two non-consecutive 24-h recalls were conducted in convenience samples of 20 rural Mayan women and 20 urban students. Diversity scores were computed using three food-group systems.Variety and diversity scores and dietary origin and characteristics were compared between settings using independent t-test or Mann-Whitney-U-test. RESULTS: Dietary variety and diversity were generally greater in the urban sample when compared to the rural sample, depending on the number of days and food-group system used for evaluation.The diet was predominantly plant-based and composed of non-fortified food items in both areas.The rural diet was predominantly composed of traditional,non-processed foods. The urban diet was mostly based on non-traditional and processed items. CONCLUSION: Considerations of intervention strategies for dietary improvement and health protection for the Guatemalan countryside should still rely on promotion and preservation of traditional food selection.

OBJETIVO: Comparar patrones y características de diversidad y variedad de la dieta de mujeres guatemaltecas. MATERIEL Y MÉTODOS: Se realizaron dos recordatorios de 24-horas en una muestra de conveniencia de 20 mujeres rurales y 20 estudiantes urbanas. Se calcularon puntajes de diversidad usando tres sistemas de grupos alimentarios. La variedad y diversidad, así como el origen y características de la dieta, se compararon entre ambos sitios. RESULTADOS: La variedad y diversidad en general fueron mayores en la muestra urbana en comparación con la muestra rural, dependiendo del número de días y del sistema de grupos de alimentos utilizados para la evaluación. La dieta rural fue predominantemente vegetal y compuesta de alimentos tradicionales no procesados. La dieta urbana estaba basada primordialmente en alimentos procesados. CONCLUSIÓN: Las consideraciones para crear estrategias de intervención para el mejoramiento de la dieta en el área rural dependen de la conservación de la selección de alimentos tradicionales.

RESUMO

BACKGROUND: In developing countries, complementary foods are often introduced earlier or later than appropriate and the quality is frequently insufficient, particularly in rural areas where complementary foods have traditionally been based on starchy gruels. Adequate intakes of a number of nutrients are recognized to be problematic in traditional complementary feeding regimens in developing societies. AIM: To determine the contribution of the complementary feeding nutrients to the estimated total nutrient intake in Guatemalan infants. METHODS: Three non-consecutive 24-hr recalls were collected from a convenience sample of mothers of 64 infants, aged 6-12 month on enrolment, in the rural Guatemalan highland village of Santo Domingo Xenacoj. Additional information on early introduction of pre- and post-lacteal feeds and on first foods and beverages was included. Human milk intakes were estimated by a model based on assumptions regarding satisfaction of weight-based daily energy needs by the combined diet. The 2004 WHO/FAO recommended nutrient intakes were used as the standard for adequate nutrient consumption. RESULTS: We observed that exclusive breastfeeding up to 6 month is rare. Mean nutrient intakes and densities were above recommended intakes for all nutrients examined, except calcium, iron and zinc. Intakes of most nutrients were greater from the complementary feeding component of the diet. Vitamin A intake was excessive due to consumption of fortified sugar. CONCLUSIONS: We conclude that intakes of most micronutrients were near recommendation levels, unusual within the complementary feeding experience in scientific literature. Calcium, iron and zinc were identified as "problem nutrients" as persistently reported in developing countries.

RESUMO

The objective of this study was to describe and compare the dietary variety, diversity, and origins of complementary foods given to urban and rural Guatemalan infants in the second semester of life. Dietary intake from a total of 128 infants of both sexes, aged 6.0 to 12.0 months on admission, from a low-income district of Guatemala City and a rural Mayan village was collected by means of 3 nonconsecutive 24-hour quantitative intake recalls and breast-feeding histories. We hypothesized that rural/urban, age, and sex differences would occur with respect to dietary variety and diversity scores and descriptive features at 7 levels, that is, animal or plant origin (animal, plant, both, or water); solids or semisolids vs soups and stews vs liquids; infant vs family foods; modern vs traditional foods; processed vs nonprocessed foods; commercial vs noncommercial foods; and fortified vs nonfortified foods. Overall dietary variety and diversity scores did not differ significantly between sampling areas or between sexes. Infants aged 9 to 12 months had a higher dietary variety and diversity than infants aged 6 to 9 months. Plant sources constituted a large part of the diet in both areas. Foods prepared specifically for infants, rather than for the household, were not common, although more common in the urban area than in the rural area. Commercial, processed, and fortified foods were commonly consumed in both settings. It can be concluded that although no geographical differences were seen in dietary variety or diversity, distinctions between types of selected and consumed foods were observed.

RESUMO

Introducción: La relación causa efecto entre la hipertensión arterial sistémica y un mayor riesgo para desarrollar síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) es aún incierta. El desconocimiento de la influencia del SAHOS sobre la hipertensión arterial ha llevado al excesivo diagnóstico de hipertensión arterial idiopática, desmotivando la búsqueda de la real causa subyacente, que en la mayoría de los casos puede deberse a trastornos del sueño. Materiales y métodos: En el presente estudio se incluyen pacientes hipertensos quienes consultaron en el centro médico ONIRIS, especializado en sueño, y se evaluó en ellos variables como índice de masa corporal, índice cintura cadera, circunferencia del cuello, tabaquismo y alcohol, para determinar cuáles de ellos desarrollaron SAHOS. Resultados: De 309 pacientes estudiados, el 67,4 por ciento fue positivo para SAHOS, confirmando algún grado de asociación entre ésta y la hipertensión arterial. Además, variables incluidas como factores de riesgo arrojaron resultados muy similares a los obtenidos en otros estudios que han demostrado dicha asociación. Conclusiones: Tiene predominio por el sexo masculino, se presenta generalmente en mayores de 50 años y obesos; dichos factores ponen en un riesgo elevado al paciente de desarrollar eventos vasculares que disminuyen la calidad de vida e incluso llevarlo a la muerte.
