Higher prolactin and vasoinhibin serum levels associated with incidence and progression of retinopathy of prematurity.

BACKGROUND: Retinopathy of prematurity (ROP) is a potentially blinding, retinal neovascular disease. Systemic prolactin accesses the retina to regulate blood vessels. Prolactin is proangiogenic and can be cleaved to antiangiogenic vasoinhibins. We investigated whether circulating prolactin and vasoinhibins associate with incidence and progression of ROP. METHODS: A prospective, longitudinal, case-control study covering postnatal weeks 1 to 9 measured serum prolactin, vasoinhibins, and vascular endothelial growth factor (VEGF) weekly in 90 premature infants diagnosed as ROP or control. RESULTS: Prolactin levels were higher in ROP than in control patients before (106.2 ± 11.3 (SEM) vs. 64.7 ± 4.9 ng/ml, postnatal week 1) and during (120.6 ± 10 vs. 84.7 ± 7.5ng/ml, postnatal week 5) ROP diagnosis. Prolactin, but not gestational age, birth weight, Apgar score, sepsis, or ventilation time, correlated with ROP. The relative risk (RR) of developing ROP increased if Prolactin (PRL) levels were higher than thresholds of 80 ng/ml (RR = 1.55, 95% CI: 1.06-2.28), 100 ng/ml (RR = 1.63, 95% CI: 1.14-2.34), or 120 ng/ml (RR = 1.95, 95% CI: 1.41-2.68). Vasoinhibin levels were 39.7% higher (95% CI: 4.5-77.5) in the circulation of ROP than in control patients at postnatal week 1 and similar thereafter, whereas VEGF serum levels were always similar. CONCLUSION: High serum prolactin and vasoinhibin levels predict and may impact ROP progression.

[Mass-gathering medical strategies: The experience in the International Book Fair in Guadalajara]. / Estrategias médicas en eventos masivos: la experiencia de la Feria Internacional del Libro de Guadalajara.

INTRODUCTION: The Guadalajara International Book Fair (FIL) is a mass gathering, hosting publishing companies from 40 countries and more than 750,000 visitors. It is necessary to prioritize preventive measures focusing on earthquakes, fires, terrorist acts, and prevention of infections. The objective of this study is to describe and analyze the health problems encountered during FIL 2013 in order to improve civil protection services during future events. MATERIAL AND METHODS: Descriptive, cross-sectional study, collecting medical histories in accordance with Mexican Official Standard NOM-004-SSA3-2012, and classifying respondents into age groups. A total of 794 medical sheets for patients who received assistance at the Mobile Health Units were analyzed. RESULTS: Altogether, 794 (0.1%) patients were medically evaluated out of 750,987 fair visitors during the study period. Of these, 32 patients were <12 years old; 111 were 13-20 years old; 540 were 20-50 years old; and 111 were >50 years old. There were no complicated medical cases. A favorable impact of preventives strategies was observed. CONCLUSIONS: Non-complicated medical incidents were observed. It is necessary to increase the knowledge on health among the general public who attend this type of event. Training health professionals is a priority in prevention measures and providing care during mass events of this kind in Mexico's territory.

[Clinical course of children of mothers with addictions into a neonatal intensive care unit in western Mexico]. / Evolución clínica de hijos de madres con adicciones internados en una unidad de terapia intensiva neonatal del Occidente de México.

BACKGROUND: Pregnancy in women addicted represents, in itself, a major risk of destruction of physical and mental health of the unborn child; urgent prevention is the same as essential to providing quality care to the mother and child knowledge. OBJECTIVE: Describe the physical and sociodemographic characteristics of neonates in intensive care units, born of mothers with addictions. MATERIALS AND METHOD: Cross-sectional, descriptive study of neonates with addict mothers, analyzing age, gender, clinical symptoms and complications. Findings for frequency-percentages with regard to qualitative variables, and medians and ranges for quantitative variables. SPSS-20.0-Windows Statistics software package. RESULTS: 618 patients admitted to the NICU, 180(29%) showing withdrawal symptoms; irritability in 117 (63%), intensive crying in 93 (51%), spontaneous Moro reflex 74 (42%), diarrhea 61 (30%), fever 61 (30%). Birth defects 124 (20%), from greater to lesser occurrence: disorders in central nervous system, digestive tract and abdominal wall, extremities, kidneys, and others. 309 (50%) weight lower than 2600g. The most frequent metabolic disorders were hypoglycemia, Metabolic Acidosis and jaundice, among others. CONCLUSIONS: Every day, we see more children born of substance-dependent mothers in the Mexico. Our study reveals high mortality rate and many complications for this group; thus, it becomes necessary to institute preventive measures among Mexican women of childbearing age in order to prevent illegal drug use and to increase treatment among pregnant addicts. Gynecologists, pediatricians and neonatologists must have extensive knowledge regarding the entire clinical-social spectrum of symptoms that may be observed in children of mothers suffering addictions.

Early retinopathy of prematurity findings identified with fluorescein angiography.

BACKGROUND: Fluorescein angiography has been fundamental for the understanding and description of vascular disorders affecting the retina and choroid. The aim of this report is to assess the early anatomic retinal changes visible with angiography, and their relation with the clinical findings of retinopathy of prematurity. METHODS: Ten babies were included in the study, the initial examination being at 2 weeks after birth. Two cycles of tropicamide 0.8 % and phenylephrine 5 % eye drops were instilled into both eyes 30 min before examination. A RetCam II was used to obtain digital retinal images, after instilling topical anesthesia (tetracain 0.5 %) and using a contact gel. Fluorescein angiography was undertaken following administration of an intravenous bolus of 0.1 ml/kg saline fluorescein 10 % followed by a 3.0-ml isotonic saline flush, with the assistance of the neonatologist; the right and left eyes were imaged. RESULTS: We observed that some of the vascular abnormalities described for threshold disease by Lepore were already present at the second week of life, preceding the diagnosis of threshold disease by 3-4 weeks in two cases. The main findings in our cases were arterio-venous shunts, surrounded by areas of capillary non-perfusion, rosary-bead-like hyper-fluorescence, tortuosity and leakage from distal arterioles, none of which were detectable in the digital fundus pictures. CONCLUSIONS: Early ROP screening at the NICU that includes FA is a safe procedure, and gives the examiner details of vascular changes that are not detectable by indirect ophthalmoscopy, which could predict the progression to threshold disease, and provide an alert about the need of therapeutic interventions.

Postnatal Serum Insulin-Like Growth Factor I and Retinopathy of Prematurity in Latin American Infants.

PURPOSE: Identifying at-risk infants for retinopathy of prematurity (ROP) is complex in countries with emerging economies as infants that lack conventional risk factors, such as low birth weight (BW) and young gestational age (GA), still go on to develop severe ROP. Potential biomarkers, like serum insulin-like growth factor 1 (IGF-1) and slow postnatal weight gain, have been identified as good predictors for ROP in developed countries. We sought to determine the relationship between IGF-1 levels and ROP in two Latin American countries where the burden of disease is still significant. METHODS: Prospective cohort study of infants in Guadalajara, Mexico and La Plata, Argentina. Filter-paper bloodspot IGF-1 assays were performed weekly from birth until hospital discharge or 40 weeks' postmenstrual age (PMA). RESULTS: 112 infants were studied with a median BW of 1412 g (range 620 g-2390 g) and a median GA of 33 weeks (range 25-37). There was no significant difference in IGF-1 between infants who developed ROP and those who did not. CONCLUSION: Low IGF-1 was not associated with ROP in these infants. The lack of an association between ROP and IGF-1 in Latin America supports the observation that growth-based predictive models do not perform as well in this setting where more mature babies still develop severe ROP.

In vivo assessment and characterization of lactic acid bacteria with probiotic profile isolated from human milk powder.

INTRODUCTION: Introduction: breast milk (MH) contains nutrients and bioactive compounds for child development, including probiotic bacteria, which contribute to intestinal maturation. This benefit accompanies the individual until adulthood. There are new methods such as spray drying that give this compound a good conservation without loss of microbiota. Objective: the aim of this study was to analyze the viability of lactic acid bacteria isolated from human milk with probiotic potential after the spray drying process, as well as to evaluate the possible adhesion in the colon of mice of the Balb/C strain after feeding them powdered human milk and a commercial formula milk. Method: we isolated and identified the presence of lactic acid bacteria with possible probiotic potential in powdered human milk using the MALDI-TOF MS technique. Powdered human milk and a commercial formula milk were fed to mice of the Bald/C strain for 14 weeks. Glucose level and weight were measured in the mice. The feces were collected to verify the presence of lactic bacteria. The mice were sacrificed and their intestines were weighed, isolating the lactic acid bacteria both from the intestines and from the feces. The strains isolated from mice fed human milk were evaluated for their probiotic potential, analyzing their ability to inhibit pathogens, resistance to pH, temperature, adhesion, and hydrophobicity. Results: the presence of Lactobacillus fermentum LH01, Lactobacillus rhamnosus LH02, Lactobacullis reuteri LH03, and Lactobacillus plantarum LH05 in powdered human milk was identified. All strains showed a possible probiotic profile due to the ability of bacteria to resist low pH, bile salts, and exposure to gastric enzymes, as well as their hydrophobicity and self-aggregation capacity, and their failure to show hemagglutination or hemolysis activity in a culture medium rich in erythrocytes. We observed that the consumption of powdered human milk prevented weight gain and constipation in mice. Conclusions: after spray drying, strains with possible probiotic potential may be preserved in human milk. The consumption of powdered human milk with probiotic bacteria prevents constipation and weight gain in mice, when compared to those fed a commercial formula milk.

INTRODUCCIÓN: Introducción: la leche materna (HM) contiene los nutrientes y compuestos bioactivos necesarios para el desarrollo infantil, incluidas bacterias probióticas, que contribuyen a la maduración intestinal. Objetivo: el objetivo de este estudio fue analizar la viabilidad de las bacterias acidolácticas aisladas de la leche humana con potencial probiótico, después del proceso de secado, así como evaluar su posible adhesión en el colón de ratones (BAlb/C) alimentados con leche humana en polvo y leche de una fórmula comercial. Método: se aislaron e identificaron mediante la técnica de Maldi-Tof-MS las bacterias acidolácticas con posible potencial probiótico en la leche humana en polvo. Se alimentó con leche humana en polvo y leche de una fórmula comercial a ratones de la cepa Bald/C durante 14 semanas. Se midieron el nivel de glucosa y el peso. Las heces se recolectaron para verificar la presencia de bacterias lácticas. Los ratones se sacrificaron y se pesaron los intestinos, aislando las bacterias lácticas tanto de los intestinos como de las heces. En las cepas aisladas de la leche humana se evaluó el potencial probiótico analizando su capacidad para inhibir patógenos, resistir distintos pH y temperaturas, adherirse y mostrar hidrofobicidad. Resultados: se identificó la presencia de Lactobacillus fermentum LH01, Lactobacillus rhamnosus LH02, Lactobacullis reuteri LH03 y L. plantarum LH05 en la leche humana en polvo. Todas las cepas mostraron resistencia a los pH bajos, a las sales biliares y a la exposición a enzimas gástricas, así como una buena hidrofobicidad y capacidad de autoagregación. Además, no presentaron actividad de hemaglutinación o hemólisis en un medio de cultivo rico en eritrocitos. Observamos que el consumo de leche humana en polvo evita en los ratones el aumento de peso y el estreñimiento. Conclusiones: después del secado por aspersión, las cepas con posible potencial probiótico pueden conservarse en la leche materna. El consumo de leche humana en polvo con bacterias probióticas evita el estreñimiento y el aumento de peso en los ratones, en comparación con los alimentados con leche de una formula comercial.

Diagnostic Yield of Population-Based Screening for Chronic Kidney Disease in Low-Income, Middle-Income, and High-Income Countries.

Importance: Population-based screening for chronic kidney disease (CKD) is sometimes recommended based on the assumption that detecting CKD is associated with beneficial changes in treatment. However, the treatment of CKD is often similar to the treatment of hypertension or diabetes, which commonly coexist with CKD. Objective: To determine the frequency with which population-based screening for CKD is associated with a change in recommended treatment compared with a strategy of measuring blood pressure and assessing glycemia. Design, Setting, and Participants: This cohort study was conducted using data obtained from studies that evaluated CKD in population-based samples from China (2007-2010), India (2010-2014), Mexico (2007-2008), Senegal (2012), and the United States (2009-2014), including a total of 126 242 adults screened for CKD. Data were analyzed from January 2020 to March 2021. Main Outcomes and Measures: The primary definition of CKD was estimated glomerular filtration rate less than 60 mL/min/1.73 m2. For individuals with CKD, the need for a treatment change was defined as not taking an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker or having blood pressure levels of 140/90 mm Hg or greater. For individuals with CKD who also had diabetes, the need for a treatment change was also defined as having hemoglobin A1c levels of 8% or greater or fasting glucose levels of 178.4 mg/dL (9.9 mmol/L) or greater. Case finding was defined as testing for CKD only in adults with hypertension or diabetes. Results: Among 126 242 adults screened for CKD, there were 47 204 patients in the China cohort, 9817 patients in the India cohort, 51 137 patients in the Mexico cohort, 2441 patients in the Senegal cohort, and 15 643 patients in the US cohort. The mean age of participants was 49.6 years (95% CI, 49.5-49.7 years) in the China cohort, 42.9 years (95% CI, 42.6-43.2 years) in the India cohort, 51.6 years (95% CI, 51.5-51.7 years) in the Mexico cohort, 48.2 years (95% CI, 47.5-48.9 years) in the Senegal cohort, and 47.3 years (95% CI, 46.6-48.0 years) in the US cohort. The proportion of women was 57.3% (95% CI, 56.9%-57.7%) in the China cohort, 53.4% (95% CI, 52.4%-54.4%) in the India cohort, 68.8% (95% CI, 68.4%-69.2%) in the Mexico cohort, 56.0% (95% CI, 54.0%-58.0%) in the Senegal cohort, and 51.9% (51.0%-52.7%) in the US cohort. The prevalence of CKD was 2.5% (95% CI, 2.4%-2.7%) in the China cohort, 2.3% (95% CI, 2.0%-2.6%) in the India cohort, 10.6% (95% CI, 10.3%-10.9%) in the Mexico cohort, 13.1% (95% CI, 11.7%-14.4%) in the Senegal cohort, and 6.8% (95% CI, 6.2%-7.5%) in the US cohort. Screening for CKD was associated with the identification of additional adults whose treatment would change (beyond those identified by measuring blood pressure and glycemia) per 1000 adults: China: 8 adults (95% CI, 8-9 adults); India: 5 adults (95% CI, 4-7 adults); Mexico: 26 adults (95% CI, 24-27 adults); Senegal: 59 adults (95% CI, 50-69 adults); and the US: 19 adults (95% CI, 16-23 adults). Case finding was associated with the identification of 46.2% (95% CI, 45.1%-47.4%) to 86.4% (95% CI, 85.4%-87.3%) of individuals with CKD depending on the country, an increase in the proportion of individuals requiring a treatment change by as much 89.6% (95% CI, 80.4%-99.3%) in the US, and a decrease in the proportion of individuals needing GFR measurements by as much as 57.8% (95% CI, 56.3%-59.3%) in the US. Conclusions and Relevance: This study found that most additional individuals with CKD identified by population-based screening programs did not need a change in treatment compared with a strategy of measuring blood pressure and assessing glycemia and that case finding was more efficient than screening for early detection of CKD.

Screening for CKD and cardiovascular disease risk factors using mobile clinics in Jalisco, Mexico.

BACKGROUND: Chronic kidney disease (CKD) is a major cause of morbidity and mortality in Mexico. However, many residents of underserved areas may be unaware that they potentially are affected. STUDY DESIGN: In an observational cross-sectional study, we examined the diagnostic yield of screening for CKD and cardiovascular disease risk factors using mobile units that traveled to poor communities in Jalisco, Mexico. SETTING & PARTICIPANTS: We excluded individuals who were aware that they had CKD and those < 18 years of age. OUTCOMES: Glomerular filtration rate, cardiovascular risk. MEASUREMENTS: Demographic data, socioeconomic status, blood pressure, fasting glucose, and dipstick urinalysis. RESULTS: 3,734 participants; 29.3% men and mean age of 57.4 +/- 13.0 years. Most (99.7%) had no history of cardiovascular disease; however, 43.5% had a history of diabetes, 11.4% had dipstick-positive proteinuria, 62.0% had blood pressure in the hypertensive range, and 15.8% had an estimated glomerular filtration rate compatible with stages 3-5 CKD. In patients with no history of cardiovascular disease, proportions with predicted 5-year risks of new cardiovascular events <5%, 5%-10%, 10.1%-20%, 20.1%-30%, and >30% were 10.0%, 11.7%, 26.6%, 20.7%, and 30.9%, respectively. Screening 18 participants aged < 40 years would be expected to detect 6 new cases of hypertension or 2 new cases of diabetes. LIMITATIONS: Data may not be generalizable to all low-income settings or other regions of Mexico. CONCLUSIONS: Impaired kidney function, proteinuria, and cardiovascular risk factors were detected frequently when mobile units were used to perform screening in poor areas of Jalisco, Mexico. This suggests that trials of targeted screening and intervention are feasible and warranted.

Prevalence of chronic kidney disease in the Kidney Early Evaluation Program (KEEP) México and comparison with KEEP US.

The National Kidney Foundation Kidney Early Evaluation Program (KEEP) is a free community screening program aimed at early detection of kidney disease among high-risk individuals. A pilot phase of KEEP México began in 2008 in México City and Jalisco State. Adults with diabetes, hypertension, or family history of diabetes, hypertension, or chronic kidney disease (CKD) were invited to participate through advertising campaigns. All participants completed a questionnaire. Blood pressure, weight, and height were measured; blood and urine tests included albuminuria and serum creatinine to estimate glomerular filtration rate using the Modification of Diet in Renal Disease Study equation. Mean age of KEEP México City and KEEP Jalisco participants was 46 and 53 years, respectively; >70% were women. CKD prevalence was 22% in KEEP México City and 33% in KEEP Jalisco, not significantly different from reported KEEP US prevalence of 26%. CKD stages 1 and 2 were more frequent in KEEP México and stage 3 in KEEP US. In KEEP México City, CKD prevalence was higher than the overall prevalence among participants with diabetes (38%) or diabetes and hypertension (42%). Most KEEP México participants were unaware of the CKD diagnosis, despite that 71% in KEEP México City had seen a doctor in the previous year. CKD is highly prevalent, underdiagnosed, and underrecognized among high-risk individuals in México. KEEP is an effective screening program that can successfully be adapted for use in México.

[Out-of-hospital delivery. Experience of ten years in Jalisco, Mexico]. / Parto fortuito. Experiencia de diez años en Jalisco, México.

BACKGROUND: Birth without medical assistance, or outs hospitals is defined as one that occurs without the optimal medical and health care conditions for mother and son pairing. Frequency of this phenomenon is not known in Mexico. OBJECTIVE: To observe clinical outcomes, morbidity, mortality, epidemiological and geographical patterns. MATERIAL AND METHOD: A retrospective study including newborns of mothers who have had deliveries without medical assistance in accidental conditions, admitted to Unidad de Cuidados Intensivos Neonatales Externos, Hospital Civil de Guadalajara Fray Antonio Alcalde (Mexico). From January 2000 to December 2009. RESULTS: In 4,762 (100%) neonatal records evaluated, 582 (12%) were newborns birth for deliveries out of hospital. 314 (54%) female and 268 (46%) male, first mother's gravidity 195 (33%) and second o more gravidity 387 (68%) were registered. The Hospital stay average was 3-day. Discharge diagnoses: healthy 463 (79%), neonatal sepsis 16 (4%), respiratory distress 35 (6%), jaundice 33 (6%), pneumonia 12 (2%), metabolic disorders 13 (3%), other diagnoses 10 (2%). Place of births: 366 Guadalajara metropolitan area (63%), state of Jalisco, 180 (31%) other states of the Mexican Republic 36 (6%). Lambed at home 117 (20%), 52 bath home (9%), toilet bowl 29 (5%), car 128 (22%), road 58 (10%), hospital admission 104 (18%), Ambulance 42 (7%) Other 52 (9%). CONCLUSION: In our study we observed that 79% of the newborns were healthy. They are the third leading cause of admission to Neonatal Intensive Care Unit External. The most common neonatal complications were solved without consequence. No neonatal mortality cases were founded.

Diagnostic Images of the Ocular Fundus Using a Low-Cost Portable Endoscope in Premature Patients at Risk of Developing Retinopathy of Prematurity.

The purpose of this article is to describe how fundus images are obtained using a low-cost device: the "Visual Ear Wax Cleaner Tool" portable endoscope (Soonhua Inc., China) connected to a smartphone, after installation of free applications ("Inskam" and "CameraFI") using the smartphone screen as a monitor and after medication mydriasis, local anesthesia, and blepharostat placement. With this endoscope, video recording and fundus imaging are easily performed, for the case of patients at the risk of developing retinopathy of prematurity (ROP), facilitating timely screening in order to start treatment in patients who require it. This fundus imaging technique shares certain similarities with the RetCam® (Clarity, Pleasaton California) system, which performs real-time fundus imaging providing the ability to record and document findings and capture images from the video footage, with high quality and definition, although with a smaller angle of vision. The capture of images using a smartphone allows storing and sharing the images. These are devices which are generally accessible and portable and which use simplified energy sources, requiring very simple training. The low-cost, easy-to-learn technique and quick sharing of images through communication networks make this a tool to be considered for the practice of telemedicine.

[Influence of the diet of Mexican women on the nutritional quality and the presence of beneficial microorganisms in human milk]. / Influencia de la dieta de mujeres mexicanas sobre la calidad nutricional y la presencia de microorganismos benéficos en la leche humana.

INTRODUCTION: Introduction: breast milk is the first fundamental food of newborns and it provides all the sources of energy, nutrients and the immunological protection they need during their first months of life. Unfortunately, there are specific circumstances that imply that the mother cannot feed her baby correctly, since the mother's nutritional needs differ to a certain extent during different periods of life. Especially in breastfeeding, since nutritional needs are increased, due to the loss of nutrients, first by colostrum and then by breast milk. Objective: to demonstrate the influence of the diet of Mexican women on the nutritional quality and the presence of beneficial microorganisms in human milk. Methods: seventy descriptive surveys of nutrition and sampling of milk to women in nursing state were carried out. The milks were subjected to various bromatological and microbiological analyzes to evaluate their nutritional quality and possible probiotic activity. Results: it was shown that the mother's food intake influences the nutritional quality of the milk. Likewise, it affects the development and growth of lactic acid bacteria. Several strains were isolated and identified in human milk of the genus Lactobacillus, as well as pathogenic bacteria such as Lodderomyces elongisporus among others. Conclusions: the mothers' nutrition is directly reflected in the nutritional quality of the milk. It was observed that the amount of essential nutrients of milk such as carbohydrates, lipids and proteins vary according to the diet and life rhythm of the mothers, as well as the significant decrease of lactic bacteria with probiotic potential.

INTRODUCCIÓN: Introducción: la leche materna es el primer alimento fundamental de los neonatos y proporciona todas las fuentes de energía, nutrientes y protección inmunológica que necesitan durante sus primeros meses de vida. Lamentablemente, existen circunstancias específicas que implican que la madre no pueda alimentar correctamente a su bebé, ya que las necesidades nutricionales de la madre difieren en cierta medida durante los diversos periodos de la vida, especialmente en la lactancia, ya que se aumentan las necesidades nutricionales debido a la pérdida de nutrientes, primero por el calostro y luego a través de la leche materna. Objetivo: demostrar la influencia de la dieta de mujeres mexicanas sobre la calidad nutricional y la presencia de microorganismos benéficos en la leche humana. Métodos: se llevaron a cabo 70 encuestas descriptivas de nutrición y toma de muestras de leche a mujeres en estado lactante. Las leches fueron sometidas a diversos análisis bromatológicos y microbiológicos para evaluar su calidad nutricional y posible actividad probiótica. Resultados: se demostró que la ingesta de alimentos de la madre influye en la calidad nutricional de la leche. Asimismo, afecta el desarrollo y crecimiento de las bacterias lácticas. Se aislaron e identificaron diversas cepas en leche humana del género Lactobacillus, además de bacterias patógenas como el caso de Lodderomyces elongisporus, entre otros. Conclusiones: la alimentación de las madres se refleja directamente en la calidad nutricional de la leche. Se observó que la cantidad de nutrientes esenciales de la leche, como son los hidratos de carbono, lípidos y proteínas, varían conforme a la alimentación y el ritmo de vida de las madres, así como la disminución significativa de bacterias lácticas con potencial probiótico.

Oxygen Monitoring Reduces the Risk for Retinopathy of Prematurity in a Mexican Population.

BACKGROUND: Retinopathy of prematurity (ROP), a potentially blinding disease, affects preterm infants. High levels of oxygen saturation are a well-known risk factor for ROP. OBJECTIVES: To assess the frequency of ROP type 1 needing treatment after improved oxygen monitoring (2011) in a Mexican preterm population selected for WINROP analyses and to retrospectively revalidate WINROP, an online surveillance system identifying infants at risk of developing ROP type 1. METHODS: Preterm infants born with birth weight (BW) <1,750 g and/or at gestational age (GA) ≤34 weeks, screened for ROP in 2012-2014 at the Hospital Civil de Guadalajara, Mexico were included (n = 151). Eighty-five infants with GA <32 weeks qualified for WINROP analyses. GA, BW, maximal ROP stage, ROP treatment and weekly weights were recorded. The results in the present study were compared to those of a previous WINROP study in the same hospital (2005-2010; n = 352). RESULTS: In the present WINROP cohort, 11.8% of the infants born at GA <32 weeks received treatment compared to 51.0% of the infants in the previous WINROP cohort. One infant (3%) born at GA ≥32 weeks received treatment during the present study period compared to 35.6% during the previous period. WINROP displayed 80.0% sensitivity in infants born at GA <32 weeks in the present study compared to 84.7% in the previous study. CONCLUSIONS: Uncontrolled oxygen supplementation is the major risk factor for severe ROP in infants born at GA ≥32 weeks. After improved oxygen monitoring, the frequency of ROP treatment was dramatically reduced at the Hospital Civil de Guadalajara, Mexico.

Embarazo ectópico abdominal de término con neonato vivo: caso clínico y revisión de la bibliografía / Advanced abdominal pregnancy with a living neonate: Case report and literature review

Resumen ANTECEDENTES: El embarazo ectópico abdominal es una alteración poco frecuente, pero con alta tasa de morbilidad y mortalidad materno-fetal-neonatal. Para establecer el diagnóstico se requiere un alto grado de sospecha y casi siempre se efectúa durante el procedimiento quirúrgico. Es el único tipo de embarazo ectópico que puede llegar a término. CASO CLÍNICO: Paciente de 35 años, con antecedente obstétrico de dos cesáreas, que acudió al servicio médico por dolor abdominal de larga evolución, con varios meses de amenorrea, sin control prenatal. El dolor fue inicialmente adjudicado a una hernia umbilical, pero ante su persistencia se reexaminó a la paciente y se encontró una masa abdominal, por lo que se sospechó embrazo ectópico. El ultrasonido abdominal y la resonancia magnética confirmaron el embarazo de término, que finalizó mediante laparotomía. Se decidió dejar la placenta in situ, debido al riesgo de hemorragia por su remoción. Tanto el neonato como la madre fueron dados de alta en buenas condiciones después de dos semanas de estancia hospitalaria, con posterior seguimiento. CONCLUSIONES: Aunque el embarazo ectópico abdominal es una alteración poco frecuente, es importante saber qué debe hacerse de acuerdo con las semanas de gestación, debido al incremento reciente en su incidencia y a la alta tasa de complicaciones, con la finalidad de preservar el bienestar materno-fetal y la fertilidad femenina.

Abstract BACKGROUND: Abdominal pregnancy is a rare clinical entity with a high risk for both the mother and the product. It's diagnosis requires a high level of suspicion, being usually made during the surgical management of the case. It is the only type of ectopic pregnancy that can reach term. CLINICAL CASE: A 35 year-old patient, with two previous cesarean deliveries, who presents with chronic abdominal pain, without prenatal consultations and with several months of amenorrhea. The pain is initially atributted to an umbilical hernia, but due to it's persistence she is re-examined, finding an abdominal mass and raising suspicion of a possible ectopic pregnancy. She's sent to a hospital in western Mexico, where she undergoes abdominal examination with ultrasound and magnetic resonance, which shows a full term abdominal pregnancy, for which a laparotomy is performed. The placenta is left in situ, due to the high risk of hemorrhage associated with it's removal. Both the newborn and the mother are released from the hospital in good conditions after two weeks of stay, with subsequent follow-up. CONCLUSIONS: Despite it being a rare condition, it's important to be acquainted with the proper management according to the gestational age of the pregnancy due to the recent rise in it's incidence, as well as it's particularly high rate of complicactions, in order to preserve the wellbeing of both patients when possible, as well as maternal fertility.

Prediction of retinopathy of prematurity using the screening algorithm WINROP in a Mexican population of preterm infants.

OBJECTIVE: To retrospectively validate the WINROP (weight, insulin-like growth factor I, neonatal, retinopathy of prematurity [ROP]) algorithm in identification of type 1 ROP in a Mexican population of preterm infants. METHODS: In infants admitted to the neonatal intensive care unit at Hospital Civil de Guadalajara from 2005 to 2010, weight measurements had been recorded once weekly for 192 very preterm infants (gestational age [GA] <32 weeks) and for 160 moderately preterm infants (GA ≥32 weeks). Repeated eye examinations had been performed and maximal ROP stage had been recorded. Data are part of a case-control database for severe ROP risk factors. RESULTS: Type 1 ROP was found in 51.0% of very preterm and 35.6% of moderately preterm infants. The WINROP algorithm correctly identified type 1 ROP in 84.7% of very preterm infants but in only 5.3% of moderately preterm infants. For infants with GA less than 32 weeks, the specificity was 26.6%, and for those with GA 32 weeks or more, it was 88.3%. CONCLUSIONS: In this Mexican population of preterm infants, WINROP detected type 1 ROP early in 84.7% of very preterm infants and correctly identified 26.6% of infants who did not develop type 1 ROP. Uncertainties in dating of pregnancies and differences in postnatal conditions may be factors explaining the different outcomes of WINROP in this population.

The utility of non-ophthalmologist examination of eyes at risk for serious retinopathy of prematurity.

BACKGROUND: Retinopathy of Prematurity (ROP) is the main cause of preventable blindness in premature babies. Currently, there is a shortage of trained ophthalmologists, which has resulted in an alarming increase in cases of vision loss and related complications. This study's aim was to determine the utility of examinations conducted by non-ophthalmologist physicians to assess posterior pole vessel abnormalities in eyes at risk for ROP. METHOD: Non-ophthalmologist physicians (pediatrician and neonatologist) were trained to use an indirect ophthalmoscope to view the posterior pole of babies at risk for ROP. Examinations were conducted on both eyes of premature infants born before 35 weeks gestational age (GA) starting at the third week after birth and weekly thereafter. The presence of Plus disease was identified by the non-ophthalmologist and results compared to the clinical examination by a pediatric ophthalmologist experienced in ROP detection and treatment. Chi-square was used for proportions and the Mann Whitney U test for medians. Fagan's nomogram was determined for diagnostic usability. The Kappa index was used to rate inter-observer agreement. RESULTS: Results of 228 examinations performed on 150 premature infants were analyzed to determine the correlation of the non-ophthalmologist findings and the eye examination. For any vascular change in posterior pole diagnostic, findings were 87% and 87% accuracy for pediatrician and neonatologist, 82% and 83% sensitivity, 90% and 90% specificity respectively. There was no significant difference found in the detection of Plus disease for the examinations performed by the ophthalmologist compared to those performed by the non-ophthalmologist (P < 0.05). CONCLUSIONS: After training in the use of an indirect ophthalmoscope, non-ophthalmologist physicians can reliably detect posterior pole retinal vessel changes for ROP diagnosis.

Farmacovigilancia en el recién nacido crítico en el estado de Jalisco: Obligación olvidada / Pharmacovigilance in the critical newborn in the state of Jalisco: Forgotten obligation

En los neonatos en estado crítico es necesario establecer un sistema de farmacovigilancia con el cual se les proteja de posibles reacciones adversas a los medicamentos; estas reacciones pueden ser por el efecto farmacológico, la interacción con otros medicamentos, errores de dosificación y la idiosincrasia del paciente, de acuerdo con la Norma Oficial Mexicana 220. Objetivo: Conocer el estado actual de la farmacovigilancia en unidades de cuidado intensivo neonatal del estado de Jalisco. Material y métodos: Mediante un cuestionario estructurado de 12 preguntas, se practicó una encuesta de opinión en referencia a los programas de farmacovigilancia en los recién nacidos en estado crítico en instituciones del área metropolitana de Guadalajara y el interior del estado de Jalisco. Se aplicó en ocho centros hospitalarios que cuentan con terapia intensiva neonatal y en un congreso estatal de pediatría en el año 2011. A todos los participantes se les pidió que de manera voluntaria, llenaran una documento ad hoc; los resultados se procesaron en el programa Epi info 2010. Discusión y conclusiones: Los resultados demuestran que no se está cumpliendo la NOM 220. Existe un gran déficit de unidades con programas implementados de farmacovigilancia y proceso de notificación de reacciones adversas a medicamentos; la cobertura es menor al 50%. Al parecer, el problema es aún mayor en instituciones particulares. Es necesario cumplir con la NOM 220 para asegurar la calidad de atención en los recién nacidos críticos en el estado de Jalisco.

There is a need to establish medication surveillance/monitoring systemsfor newborn patients in critical condition in order to protect these patients from possible adverse reactions to prescribed drugs. In accordance with Mexican official standard NOM 220, these reactions may result from pharmacological effects, interaction with other drugs, dosage errors, and the patient's nature/idiosyncrasy. Objective: Our goal was to gain knowledge on the current situation regarding medication surveillance in neonatal intensive care units within the state of Jalisco. Material and methods: By means of a structured questionnaire involving 12 questions, an opinion poll was carried out with reference to medication surveillance programs for newborn patients in critical condition at institutions within Guadalajara's metropolitan area and the State of Jalisco. The survey was conducted in 8 hospital centers that provide neonatal intensive care and at a state congress on pediatrics that took place in 2011. All of the respondents were asked to voluntarily fill out a questionnaire Ad-hoc, and the results were processed using the Epi Info 2010 program. Discussion and conclusions: The results show that there is widespread noncompliance of NOM 220. There is a considerable deficit with respect to units implementing medication surveillance systems and methods to notify adverse reactions to medication, with implementation rates lower than 50%. It appears that the problem is even greater in private institutions. Compliance with NOM 220 is essential in order to guarantee the quality of the care provided to newborn patients in critical condition within the state of Jalisco.

Retinopatía del prematuro: controversias en el uso de antiangiogénicos intraoculares / Retinopathy of prematurity: controversies in the usage of intraocular antiangiogenics

El aumento en la sobrevida de los recién nacidos prematuros, las características del cuidado neonatal y la escasez de programas para la prevención, detección y tratamiento de la retinopatía del prematuro provocan que esta enfermedad sea la principal causa de ceguera infantil prevenible en México. El advenimiento de agentes antiangiogénicos de uso oncológico, y su uso -no autorizado, aunque con buenos resultados- en el tratamiento de enfermedades vaso proliferativas en la retina del paciente adulto, así como la presencia de reportes anecdóticos en la literatura y series de casos con serias fallas metodológicas han sugerido su utilización en el tratamiento de la retinopatía del prematuro. Desafortunadamente, estos agentes, utilizados indiscriminadamente, presentan absorción sistémica y causan efectos secundarios en el organismo del paciente prematuro. Además, no existen estudios de seguimiento a largo plazo que garanticen la seguridad de su uso en esta población. El presente artículo describe la situación en nuestro país y advierte sobre los riesgos de estos medicamentos en la población de pacientes prematuros.

The increase in survival rates among preterm infants, characteristics of neonatal care for such infants and a lack of suitable programs for preventing, detecting and treating retinopathy of prematurity (ROP) are factors that have made this disease the main cause of preventable blindness among children in Mexico. The advent of antiangiogenic agents in cancer treatment and their off-label use with favorable results in the treatment of proliferative vessel disease of the retina among adult patients, as well as anecdotal reports in the literature and a series of cases showing serious methodological flaws, have prompted their use in the treatment of retinopathy of prematurity. Unfortunately, these agents used indiscriminately in our country have a systemic absorption and secondary effects on the preterm patient's body. There are no long-term monitoring studies that guarantee their safe use in this segment of the population. This article describes the situation in our country and warns of the risks posed by the use of this type of drug on the preterm infant population.

Malformaciones congénitas como causa de hospitalización en una Unidad de Terapia Intensiva Neonatal / Congenital malformations as a cause of hospitalization in a Neonatal Intensive Care Unit

Introducción: Las malformaciones congénitas (MC) son un problema importante de salud pública y la principal causa de muerte en niños. Representan el 20% de la mortalidad infantil en el primer año de vida. Objetivo: Evaluar la contribución de las MC como causa de hospitalización en una Unidad de Terapia Intensiva Neonatal, basado en el uso de datos obtenidos de una población de neonatos. Material y métodos: Estudio descriptivo en 2,907 neonatos del año 2005-2009, evaluados y categorizados por MC a través de CIE-10, OMS, obtenido por medio del expediente clínico al ingreso a la UCINEX, Hospital Civil de Guadalajara ''Fray Antonio Alcalde''. Los resultados fueron evaluados en porcentaje y medidas de tendencia central. Resultados: Doscientos noventa y cinco neonatos (10%) presentaron MC; 67% fueron masculinos y 33%, femeninos. Mielomeningocele fue la MC más frecuente (13%), mientras que el aparato gastrointestinal fue el más afectado con 27% de las MC. Las anormalidades cromosómicas generaron la estancia intrahospitalaria más elevada (20.5 ± 5.5 días), el sistema cardiovascular presentó 34% de defunción. La mortalidad resultó en 14.2%; 60% de las MC se intervinieron quirúrgicamente y el 64.5% radicaba en la zona metropolitana del Estado de Jalisco. Conclusiones: El conocimiento de la contribución de las MC en la mortalidad neonatal es importante para la integración de medidas preventivas y planificación de estrategias eficaces de atención a la salud, especialmente en las causas, tratamiento y prevención de estos trastornos. Esta información resalta la importancia de estudiar más a fondo el reconocimiento precoz de la morbimortalidad en la población pediátrica.

Introduction: Congenital malformations (CM) are a major public health problem and the leading cause of death in children; representing 20% of infant mortality in the first year of life. Objective: To evaluate the contribution of CM as a cause of hospitalization in a Neonatal Intensive Care Unit. Material and methods: We performed a retrospective, observational, transversal and descriptive study, in which we reviewed the medical records of 2,907 neonates, which entered the External Service of Neonatal Intensive Care (UCINEX) of the Hospital Civil de Guadalajara ''Fray Antonio Alcalde'', in the period 2005-2009 with the diagnostic of congenital malformations (CM) according to the WHO ICD-10. Statistics: measures of central tendency and percentages were done. Results: Two hundred ninety five infants (10.14%) had CM, 67% male and 33% female. CM myelomeningocele was the most frequent (12.9%). The gastrointestinal tract was the most affected with 27.4% of CM, chromosomal abnormalities generated more days of hospitalization (20.5 ± 5.5 days), the cardiovascular system showed 34.2% of deaths. The overall mortality was 14.2%; 60% of CM was treated surgically and 64.5% of the mothers of these infants were living in the metropolitan area of Jalisco State. Conclusions: Knowledge of the contribution of CM to neonatal mortality is important for the integration of preventive measures and plan effective strategies for its prevention, identify their causes and establish treatment. This information highlights the importance of further study of early recognition of the morbidity and mortality in the pediatric population.
