Abstract
Health systems in Latin America face many challenges in controlling the increasing burden of diabetes. Digital health interventions are a promise for the provision of care, especially in developing countries where mobile technology has a high penetration. This study evaluated the effectiveness of the implementation of a Diabetes Program (DP) that included digital health interventions to improve the quality of care of persons with type 2 Diabetes (T2DM) in a vulnerable population attending the public primary care network. MATERIALS AND METHODS A quasi-experimental pre-post uncontrolled study was conducted in 19 primary care centers and hospitals in the province of Corrientes, Argentina. We included persons with T2DM, age > = 18 years with access to a mobile phone. The multicomponent intervention included a mobile app with a diabetes registry, a clinical decision support tool for providers and a text messaging intervention for patients. RESULTS AND DISCUSSION One thousand sixty-five participants were included, 72.8% had less than 12 years of formal education and 53.5% lacked health coverage. Comorbidities were hypertension (60.8%) and overweight/obesity (88.2%). During follow-up there was a significant increase in the proportion of participants who underwent laboratory check-ups (HbA1c 20.3%-64.4%; p < 0.01) and foot exams (62.1%-87.2%; p < 0.01). No changes were observed at 12 and 24 months in the proportion of participants with poor metabolic control. The proportion of participants with uncontrolled blood pressure (≥ 140/90 mmHg) decreased from 47.2% at baseline to 30.8% at 24 months in those with a follow-up visit. CONCLUSION The DP was innovative by integrating digital health interventions in the public primary care level. The study showed improvements in quality indicators related with diabetes care processes and in blood pressure control.

Abstract
Objetivo. Caracterizar el contenido de los productos comunicacionales dirigidos a la población general para la prevención de la COVID-19 promovidos por los gobiernos de América Latina y el Caribe (ALC). Métodos. Estudio descriptivo, trasversal y exploratorio de los productos comunicacionales publicados hasta el 28 de febrero del 2021 en los sitios web oficiales de los ministerios de salud de los 47 países y territorios de ALC para la prevención de la COVID-19. Se emplearon métodos cuantitativos y cualitativos a partir de dimensiones recomendadas por la Organización Mundial de la Salud (OMS) y un enfoque de determinantes sociales de la salud (DSS). Se utilizó la técnica de análisis de contenido y triangulación por observador. Resultados. Se analizaron 3 253 productos informativos; en los 47 países y territorios de ALC, al menos un producto incluyó alguna recomendación de la OMS y en 46 se abordó alguna de las categorías y subcategorías relacionadas con los DSS intermedios. De los DSS estructurales, se aplicó el enfoque de género y alguna lengua indígena en al menos un producto de solo 4 y 7 países, respectivamente. En 35 países se encontró al menos un producto con información errónea y en 13 no se abordó la infodemia. Conclusiones. Se encontró una cantidad considerable de productos comunicacionales para la prevención de la COVID-19, pero no reflejaban un adecuado enfoque de diversidad y salud integral, y mostraban vacíos y errores de comunicación. Los países deben revisar sus políticas de comunicación en salud en el contexto de la pandemia.

Abstract
Background The northeastern region of Argentina has the highest age-adjusted cervical cancer mortality rates. Given the strong link between HPV infections and cervical cancer, one of the main interventions is the population-based use of HPV vaccines. However, the acceptability is not very clear in low- and middle-income countries. The purpose of this study was to estimate the level of HPV vaccine acceptance and associated determinants among caregivers of girls in a northeastern city of Argentina. Methods A school-based survey was conducted in 2015 using a multistage sampling method. The primary sample unit were schools stratified by socioeconomic status selected at random, and caregivers of school girls were interviewed. The acceptability was determined using the adapted Theory of Planned Behavior. We performed logistic regression models to assess associated determinants. Results The study included 347 caregivers. The intention to vaccinate was 59.88%. A positive attitude of caregivers (aOR 4.67; 3.11–7.03) and positive influence of social norms (aOR 1.95; 1.03–3.70) were the main predictors independently associated to the intention to vaccinate against HPV. In contrast, practicing a Christian non-Catholic religion decreased the intention to vaccinate against HPV (OR 0.59; 0.36–0.95). All other factors evaluated were not significantly associated with intention to vaccinate against HPV. Conclusions This study shows that evaluating attitudes, normative social beliefs, and perceived self-efficacy regarding HPV vaccination can be of utmost importance for mapping and planning of health-related strategies in developing countries.

Abstract
BACKGROUND There is an urgent need to define appropriate intervention strategies to control blood pressure in low- and middle-income countries. In 2018, a program proven effective in Argentina was translated to Guatemala's public primary health care system in rural and primarily indigenous communities. OBJECTIVES This paper describes the stakeholder engagement process used to adapt the program to the Guatemalan rural context prior to implementing a type II hybrid effectiveness-implementation trial and shares lessons learned. METHODS We identified key differences in the 2 contexts that are relevant to translating the intervention to the Guatemalan context. Alongside interviews and focus group discussions, we conducted consultation workshops in July and August 2018, applying a participatory translation process involving patients, family members, community members, health care providers, and Ministry of Health officials. The process consisted of multiple meetings in Guatemala City, as well as meetings in each of the 5 departments where the study will be implemented, and 1 district per department. During the workshops, we presented the evidence-based experience from Argentina and then focused on the challenges and recommended solutions that the participants identified for each of the intervention's 6 components. The process concluded with a meeting in which the research team and Ministry of Health officials defined specific details of the intervention. RESULTS The outcome of the process is an adapted approach appropriate to integrate into Guatemala's public primary health care system in the trial phase. The approach considers the challenges and recommended strategies for each of the 6 intervention components. CONCLUSIONS We identified lessons learned, challenges, and opportunities during the adaptation process. Findings will inform ongoing stakeholder engagement during the study implementation and future scale-up and efforts to translate evidence-based hypertension control strategies to low- and middle-income countries globally.

Abstract
OBJECTIVE To evaluate the impact of a community program aimed at improving the children mal nutrition in a rural community of the State of Chiapas, Mexico, 2013. MATERIAL AND METHOD Des criptive study of the evaluation program from a secondary database of nutritional data registry of 113 children under five years of age in a rural area of Mexico. The intervention and the survey were carried out during 2013. Baseline and 4-month measurements were recorded. The World Health Organization (WHO) Anthro software was used to calculate nutritional status indicators. According to WHO guidelines, the following data were estimated: weight for age (W/A), height for age (H/A), weight for height (W/H), and Body mass index for age (BMI/A). Position and dispersion measures were calculated; Student's T-test, Kruskal-Wallis, and MacNemar test were used for paired data and linear regression. RESULTS Between the beginning and the end, the median of the Z W/H went from -0.7 (p25 -1.24, p75 -0.01) to -0.62 (p25 -1.09, p75 -0.15). The prevalence of low weight decreased from 5.31% (CI 2.38-11.44) to 4.42% (CI 1.83-10.32) (Z BMI/A). The appropriate weight according to Z score W/H increased from 78.76% (CI 70.12-85.43) to 84.96% (76.98-90.51). In the subgroup with low initial weight, the mean of Z BMI/A and Z W/H increased 0.4 (p = 0.003). The change in the mean of Z W/H was 0.02 points in the subgroup that received the direct transfer program and of -0.3 in which it did not (p = 0.020). CONCLUSIONS It is concluded that the community program during the four months of implementation contributed to improve some anthropometric indicators, although no apparent effects were found in indicators related to chronic malnutrition.

Abstract
Background Control of cardiovascular disease ( CVD ) risk factors is suboptimal in Argentina, despite the government's provision of free blood pressure and cholesterol-lowering medications for people without private insurance. We assessed whether community health workers' use of an integrated mH ealth tool encourages patients to attend visits at primary care clinics to improve CVD risk management in 2 provinces of Argentina. Methods and Results We conducted a pragmatic cluster randomized trial, with primary care clinics randomly assigned to intervention or control. Eligible people were aged 40 to 79 years, lived in the catchment area of primary care clinics, possessed a mobile phone for personal use, had public health coverage, and a 10-year CVD risk ≥10%. In the control arm, community health workers screened for CVD risk using a paper-based tool and encouraged high-risk people to present to the primary care clinics for care. In the intervention arm, community health workers used the mH ealth tool to calculate CVD risk and confirm a scheduled physician appointment. Primary outcomes were the proportion of participants who attended a baseline visit and completed at least 1 follow-up, respectively. We enrolled 755 people (376 interventions; 379 controls). Intervention participants were significantly more likely to complete baseline visits (49.4% versus 13.5%, P value 0.0008) and follow-up visits (31.9% versus 7.7%; P value 0.0041). The use of chronic medication and current smoking were significant predictors of primary outcomes. Conclusions Use of mH ealth tools identifies patients at high CVD risk in their home, increases the likelihood of participating in chronic CVD risk factor management, and strengthens referrals.

Abstract
Background Engagement in self-care behaviors that are essential to optimize diabetes care is challenging for many patients with diabetes. mHealth interventions have been shown to be effective in improving health care outcomes in diabetes. However, more research is needed on patient perceptions to support these interventions, especially in resource settings in low- and middle-income countries. Objective The goal of the research was to explore perceptions and acceptability of a short message service (SMS) text messaging intervention for diabetes care in underserved people with diabetes in Argentina. Methods A qualitative exploratory methodology was adopted as part of the evaluation of a program to strengthen diabetes services in primary care clinics located in low-resource settings. The diabetes program included a text messaging intervention for people with diabetes. A total of 24 semistructured telephone interviews were conducted with people with diabetes. Results Twenty-four middle-aged persons with diabetes were interviewed. Acceptability was considered adequate in terms of its actual use, frequency, and the role of texts as a reminder. We found that text messages could be a mediating device in the patient’s learning processes. Also, being exposed to the texts seemed to help bring about changes in risk perception and care practices and to function as psychosocial support. Another relevant finding was the role of text messaging as a potential facilitator in diabetes care. In this sense, we observed a strong association between receiving text messages and having a better patient-physician relationship. Additionally, social barriers that affect diabetes care such as socioeconomic and psychosocial vulnerability were identified. Conclusions Our findings show positive contributions of a text messaging intervention for the care of people with diabetes. We consider that an SMS strategy has potential to be replicated in other contexts. However, further studies are needed to explore its sustainability and long-term impact from the perspective of patients.

Abstract
mHealth constitutes a promise for health care delivery in low- and middle-income countries (LMICs) where health care systems are unprepared to combat the threat of noncommunicable diseases (NCDs). This article assesses the impact of mHealth on NCD outcomes in LMICs. A systematic review identified controlled studies evaluating mHealth interventions that addressed NCDs in LMICs. From the 1274 abstracts retrieved, 108 articles were selected for full text review and 20 randomized controlled trials were included from 14 LMICs. One-way SMS was the most commonly used mobile function to deliver reminders, health education, and information. mHealth interventions in LMICs have positive but modest effects on chronic disease outcomes.

Abstract
OBJECTIVE To identify the sequence of progression of arterial and venous Doppler abnormalities from the onset of placental insufficiency in intrauterine growth restriction (IUGR). METHODS Prospective observational study of singletons with IUGR (abdominal circumference < 5(th) percentile) who underwent serial standardized umbilical artery (UA), middle cerebral artery (MCA), ductus venosus (DV) and umbilical vein (UV) Doppler surveillance. Time intervals between progressive Doppler abnormalities and patterns of deterioration were related to UA Doppler status and gestational age. RESULTS Six hundred and sixty-eight longitudinal examinations were performed in 104 fetuses, identifying three patterns of progression: (1) Mild placental dysfunction (n = 34) that remained confined to the UA/MCA. The UA became abnormal at a median of 32 weeks' gestation but the pulsatility index never exceeded 3 SD above normal. Progression took a median of 33 days, requiring delivery at a median of 35 weeks. (2) Progressive placental dysfunction (n = 49). Initially normal UA Doppler PI at 29 weeks' gestation increased beyond 3 SD, progressing to abnormal MCA, absent/reversed UA diastolic flow, abnormal DV, UV pulsations in 9-day intervals requiring delivery by 33 weeks. (3) Severe early-onset placental dysfunction (n = 21). Markedly elevated UA PI established by 27 weeks' gestation was associated with rapid (7-day intervals) progression to abnormal venous Doppler with median delivery at 30.6 weeks. Gestational age at onset, time to delivery and progression intervals were different between patterns (all P < 0.05). CONCLUSION The characteristics of cardiovascular manifestations in IUGR are determined by the gestational age at onset and the severity of placental disease. Recognition of these factors is critical for planning fetal surveillance in IUGR.

OBJECTIVE To investigate the performance of non-stress test (NST), computerized fetal heart rate analysis (cCTG), biophysical profile scoring (BPS) and arterial and venous Doppler ultrasound investigation in the prediction of acid-base status in fetal growth restriction. METHODS Growth-restricted fetuses, defined by abdominal circumference < 5(th) percentile and umbilical artery (UA) pulsatility index > 95(th) percentile, were tested by NST, cCTG, BPS, and UA, middle cerebral artery (MCA), ductus venosus (DV) and umbilical vein (UV) Doppler investigation. The short-term variation (STV) of the fetal heart rate was calculated using the Oxford Sonicaid 8002 cCTG system. Relationships between antenatal test results and cord artery pH < 7.20 were investigated, using correlation, parametric and non-parametric tests. RESULTS Fifty-six of 58 patients (96.6%) received complete assessment of all variables. All were delivered by pre-labor Cesarean section at a median gestational age of 30 + 6 weeks. The UA pulsatility index (PI) was negatively correlated with the cCTG STV (Pearson correlation - 0.29, P < 0.05). The DV PI was negatively correlated with the pH (Pearson correlation - 0.30, P < 0.02). The cCTG mean minute variation and pH were not significantly correlated (Pearson correlation 0.13, P = 0.34). UV pulsations identified the highest proportion of neonates with a low birth pH (9/17, 53%), the highest number of false positives among patients with an abnormal BPS, abnormal DV Doppler and a STV < 3.5 ms, and also stratified false negatives among patients with an equivocal or normal BPS. Abnormal DV Doppler correctly identified false positives among patients with an abnormal BPS. cCTG reduced the rate of an equivocal BPS from 16% to 7.1% when substituted for the traditional NST. Elevated DV Doppler index and umbilical venous pulsations predicted a low pH with 73% sensitivity and 90% specificity (P = 0.008). CONCLUSION In fetal growth restriction with placental insufficiency, venous Doppler investigation provides the best prediction of acid-base status. The cCTG performs best when combined with venous Doppler or as a substitute for the traditional NST in the BPS.

Abstract
BACKGROUND Previously reported pathological series suggest that cardiac malformations are universal in trisomy 18. We examined our experience of fetal echocardiography in trisomy 18 for comparison. METHODS Of 255 fetuses with trisomy 18 detected in our centre between January 1999 and June 2004, 174 were evaluated using fetal echocardiography. Our results were compared to four previous echocardiographic and four autopsy series, comprising 89 and 110 patients, respectively. RESULTS Of these 174 fetuses, 114 were examined between 10 and 14 weeks gestation and the remainder between 15 and 33 weeks. An increased nuchal translucency measurement was the reason for referral in most of the early cases and extracardiac anomalies in the remainder. Images were non-diagnostic in 12 cases (7%), all examined at <15 weeks gestation. Abnormal cardiac findings were detected in 118 of the remaining 162 fetuses (73%), including 15 with functional anomalies. The various heart malformations included ventricular septal defects, tetralogy of Fallot, left heart disease, and atrioventricular septal defects. In all series used for comparison, a similar diversity of disease was seen. In pathological series of trisomy 18, structural heart malformations were found in all cases, but some had lesions which would not be detectable echocardiographically in the fetus. CONCLUSION Abnormal cardiac findings are detectable echocardiographically in the majority of cases of trisomy 18 examined during fetal life, but not in all. A wide spectrum of heart defects is seen. Diagnosis of heart malformations can be made reliably, even in the first trimester at the time of nuchal translucency measurement.

Abstract
OBJECTIVE The study of the antioxidant status in female adolescents (N = 82) with anorexia nervosa, by the measurement of erythrocyte tocopherol concentration, and the determination of activities of the main antioxidant enzymes: superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase. METHOD Tocopherol was measured by high-performance liquid chromatography (HPLC) with ultraviolet (UV) detection, and antioxidant enzyme activities by spectrometric methods using a Cobas Fara automated centrifugal analyzer. RESULTS Tocopherol was significantly decreased in the anorexic patients compared to reference values (p < .02). In 21% of patients, tocopherol levels were below the reference interval. Superoxide dismutase activity was significantly decreased (p < .0001), while catalase activity was increased (p < .0001). The activity of the glutathione system enzymes did not show significant differences between patients and controls. DISCUSSION The deficient concentration of erythrocyte tocopherol together with the altered antioxidant enzyme activities suggest a certain degree of oxidative damage in anorexia nervosa owing to both factors deficient micronutrient intake and oxidative stress.

Abstract
OBJECTIVE To evaluate the amino acid profile in a group of adolescents with anorexia nervosa, and to apply alternative ways of presenting and assessing results, so as to increase the information available for understanding the metabolic abnormalities developed in these patients. DESIGN Plasma amino acid concentrations of a random group of patients with anorexia nervosa compared with values obtained from a 'healthy' adolescent population. SETTING The study was performed at the tertiary children's Hospital Sant Joan de Deu. SUBJECTS Female adolescents (n = 92, age: 15+/-1.8 y) at diagnosis of anorexia nervosa. Reference values for amino acids were obtained from apparently healthy adolescents (by history and analytical data) who underwent presurgical analysis for minor operations. INTERVENTIONS Plasma amino acid concentrations were measured by ion exchange chromatography. Basic laboratory analysis, carnitine and IGF-I were also determined. RESULTS In anorexic patients plasma concentrations of taurine, asparagine, glutamine, glycine, methionine, phenylalanine, ornithine, and histidine were significantly higher than reference values (Mann-Whitney, P < 0.01-0.0001), whereas arginine and cystine were lower than our reference values (P < 0.0001). Relative amino acid values (the molar fraction of the patient medians relative to control medians) were plotted. The ratios of some amino acids were significantly greater than those obtained from the reference population: Phe/Tyr (P < 0.001), Met/Cys (P < 0.0001), and Gly/Val (P < 0.01). CONCLUSIONS A trend to hyperaminoacidemia is a common feature in anorexia nervosa. Although absolute amino acid values cannot play a significant role in the assessment of nutritional status in this condition, the calculation of some ratios (Phe/Tyr, Met/Cys and Gly/Val) and the graphical representation of relative values may be useful. The plasma amino acid profile in anorexia nervosa is different from those of other severe malnutrition states, showing a marasmic pattern of balanced protein-energy undernutrition. Cystine and arginine may be considered limiting amino acids in this disease, and the consequences of their deficient concentrations for oxidative damage should be further evaluated.

Abstract
Abnormal oxidative stress was observed in some inborn errors of metabolism owing to the accumulation of toxic metabolites leading to excessive free radical production and to the influence of restricted diets on the antioxidant status. Erythrocyte antioxidant enzymes activities and tocopherol concentrations were measured in a group of phenylketonuric (n = 42) and mild-hyperphenylalaninemic (n = 28) patients compared with 45 age-matched controls. We also determined plasma selenium levels in these groups. We also evaluated the possible relationship between antioxidant status and neuropsychological disorders. Erythrocyte glutathione peroxidase (GSH-Px) activity was significantly lower (P < 0.001) in both phenylketonuric and mild-hyperphenylalaninemic patients compared with the control group, but no differences were observed between the two groups of patients. Neuropsychological disturbances were more frequent in the group of PKU patients with low GSH-Px activity than in PKU patients with normal GSH-Px. Low GSH-Px activity might be explained in phenylketonuria as a result of a selenium deficiency caused by a poor selenium intake or absorption, but not in mild hyperphenylalaninemic patients with free diet. Selenium levels were normal in both groups of patients, so low glutathione peroxidase activity in both phenylketonuric and hyperphenylalaninemic groups might be influenced by other factors, such as the consequences of an unbalanced amino acid profile, common to both conditions.

Abstract
OBJECTIVE The measurement of plasma total-homocysteine (tHcy) as a marker of folate and cobalamin status in patients with anorexia nervosa. DESIGN Plasma tHcy, folate, cobalamin and other determinants of tHcy of a random group of patients with anorexia nervosa were compared with our own reference values. SETTING The study was performed at the tertiary children's Hospital Sant Joan de Déu. SUBJECTS All the female adolescents (n=43) coming to the Hospital during a one-year period, who were diagnosed with anorexia nervosa. Reference values for tHcy were simultaneously performed with apparently healthy adolescents (by history and analytical data) who underwent presurgical analysis for minor interventions, and other magnitudes we used our own reference values. INTERVENTIONS Plasma tHcy was measured by reverse phase HPLC with fluorescence detection of the SBDF derivatives. Folate and cobalamin concentrations were determined by radioimmunoassay. RESULTS tHcy was significantly increased in anorexic patients compared to reference values (Mann-Whitney, P < 0.0001-0.001). Values were above reference range in 34% of patients, and high-normal range in 53% of patients. tHcy concentrations lowered in 8 and 11 patients after nutritional rehabilitation. Cobalamin and folate were in the reference range except for one case. No significant correlation was found among tHcy, vitamins and other determinants of tHcy concentration. CONCLUSIONS tHcy concentrations appear significantly increased in adolescents with anorexia nervosa, most probably owing to subclinical folate deficiency. This might be caused by both, intracellular folate deficiency and impaired availability. Abnormal plasma tHcy values were completely corrected after nutritional rehabilitation.

Abstract
Red blood cell tocopherol was measured in a group of 92 children with inborn errors of intermediary metabolism to evaluate the peroxidative damage in different mitochondrial and cytosolic defects, and to consider the need for treatment or vitamin supplementation. Tocopherol was determined by HPLC with UV detection. Results were expressed in nanomoles red blood cell tocopherol per gram protein. Significant differences (Mann-Whitney; P < 0.001) were found between tocopherol levels in untreated patients: 19 with mitochondrial defects versus 23 with cytosolic enzyme or transport defects, and versus 58 age-matched reference values. In conclusion, mitochondrial enzyme deficiencies, either amino and organic acidurias or defects of energy metabolism, seem to produce an excess of free radicals with the consequent utilization of tocopherol as antioxidant. This is not apparent in the cytosolic enzyme defects studied, whose tocopherol levels are in the normal range. Treatment with tocopherol completely corrects the deficient antioxidant status.

Abstract
BACKGROUND Insulin-dependent diabetes mellitus (IDDM) is characterized by an increased risk of having cardiovascular diseases which have been associated to, among other factors, an increase in lipoprotein (a) [Lp(a)] levels. METHODS With the aim of analyzing the relationship between Lp(a) plasma levels and the degree of metabolic control in infantile diabetes mellitus their levels have been evaluated in children with IDDM and correlated with the degree of metabolic control and the length of disease evolution. The study was performed in a sample of 41 children diagnosed with IDDM and ages ranging from 2 to 9 years, and 82 normolipemic healthy children corresponding to the same ages and an equal proportion by sex. Cholesterol and total triglycerides, HDL, LDL and VLDL cholesterol, apolipoproteins AI and B were determined in all. Fasting glycemia, glycohemoglobin, serum fructosamine and creatinine clearance were used as markers of metabolic disease control. RESULTS No significant differences were observed in the Lp(a) values among sexes or age in the control group. Upon comparison of the Lp(a) values of the diabetic patients with the control group, no significant differences were observed. In the diabetic children, no differences were found between the Lp(a) values according to the glycohemoglobin values (X +/- SD g/l) (< 8% 0.16 +/- 0.13); (> or = 8% 0.21 +/- 0.26). The Lp(a) values were only increased in diabetic children with more than 5 years of evolution (control: 0.12 +/- 0.14, IDDM < or = 5 years; 0.16 +/- 0.16 and IDDM > 5 years: 0.34 +/- 0.31 [p < 0.01]). CONCLUSIONS The plasma levels of Lp(a) in diabetic children are significantly related to the length of disease evolution and are independent of the degree of metabolic control.

Abstract
We present the case of a young patient with a history of alcoholism and chronic relapsing pancreatitis, who developed an associated pseudocyst. During the course of the disease he presented an acute abdomen due to splenic rupture and splenic thrombosis, disclosed by laparotomy. Following splenectomy and drainage the evolution was satisfactory. In the present paper we discuss the presentation of splenic vein thrombosis and splenic rupture as a rare complication of pancreatic pseudocyst.
