Effects of Formula Milk Feeding in Premature Infants: A Systematic Review.

The preterm baby is born at a critical period for the growth and development of the gastrointestinal and neuromotor systems. Breast milk is the food of choice for infants during the first months of life, as it provides multiple short- and long-term benefits to preterm and sick newborns. Despite this, breastfeeding is often nutritionally insufficient, requiring the addition of fortifiers. In other cases, it is important to ensure the necessary nutrients and calories, which can be provided by formula milk or pasteurized and fortified donated human milk. However, the specific guidelines for the use of formula milk have not yet been determined. Therefore, a systematic search was considered necessary in order to identify the effects of feeding with formula milk in preterm infants. A systematic search in Scopus, Medline, Pubmed, Cinahl, ClinicalTrials and Web of Science with the terms Infant Formula and Infant Premature was conducted. A total of 18 articles were selected, of which, eight were experimental and ten were observational studies. Among the objectives of the analyzed investigations, we distinguished nine that compared the effects of feeding with formula milk, breast milk and donated human milk, five that evaluated the effects of different compositions of formula milk and/or fortifiers and four investigations that compared the effects of formula milk and donated human milk. In conclusion, when breast milk is insufficient or unavailable, formula milk is a good nutritional option, due to its higher caloric density and protein content. Nevertheless, the preterm infant's diet should incorporate breast milk to reduce the incidence of morbidities such as necrotizing enterocolitis and sepsis (related to hospital handling of fortifiers and formula milk).

Estratificación basal de riesgo en pacientes mayores de 75 años con infarto y shock cardiogénico referidos para angioplastia primaria / Baseline risk stratification of patients older than 75 years with infarction and cardiogenic shock undergoing primary angioplasty

Introducción y objetivos: Los pacientes mayores de 75 años con infarto agudo de miocardio con elevación del segmento ST sometidos a angioplastia primaria en situación de shock cardiogénico sufren una gran mortalidad. La identificación previa al procedimento de variables predictoras de la posterior mortalidad sería muy útil para guiar la toma de decisiones. Métodos: Análisis del registro multicéntrico de angioplastia primaria en pacientes mayores de 75 años (ESTROFA MI+75), que incluye a 3.576 pacientes. Se analizaron las características y la evolución clínica del subgrupo con shock cardiogénico para identificar predictores de supervivencia a 1 año tras la angioplastia y elaborar un índice pronóstico. Se validó el índice en una cohorte independiente. Resultados: Se incluyó a 332 pacientes. Los predictores basales independientes fueron: la localización anterior (HR=2,8; IC95%, 1,4-6,0; p=0,005), una fracción de eyección<40% (HR=2,3; IC95%, 1,14-4,50; p=0,018) y un tiempo entre el inicio de los síntomas y la angioplastia >6 h (HR=3,2; IC95%, 1,6-7,5; p=0,001). Se diseñó un índice basado en estas variables (índice «6-ANT-40»). La supervivencia a 1 año fue del 54,5% de aquellos con índice 0, el 32,3% con índice 1, el 27,4% con índice 2 y el 17% con índice 3 (p=0,004, estadístico C=0,70). En una cohorte independiente de 124 pacientes, las supervivencias a 1 año fueron del 64,5, el 40,0, el 28,9 y el 22,2% respectivamente (p=0,008; estadístico C=0,68). Conclusiones: Un índice basado en simples variables clínicas previas al procedimiento (localización anterior, fracción de eyección<40%, demora >6 h) permite estimar la supervivencia tras una angioplastia primaria de los pacientes mayores con shock cardiogénico, y así ayudar en la toma de decisiones

Background and objectives: Patients older than 75 years with ST-segment elevation myocardial infarction undergoing primary angioplasty in cardiogenic shock have high mortality. Identification of preprocedural predictors of short- and long-term mortality could be useful to guide decision-making and further interventions. Methods: We analyzed a nationwide registry of primary angioplasty in the elderly (ESTROFA MI+75) comprising 3576 patients. The characteristics and outcomes of the subgroup of patients in cardiogenic shock were analyzed to identify associated factors and prognostic predictors in order to derive a baseline risk prediction score for 1-year mortality. The score was validated in an independent cohort. Results: A total of 332 patients were included. Baseline independent predictors of mortality were anterior myocardial infarction (HR 2.8, 95%CI, 1.4-6.0; P=.005), ejection fraction<40% (HR 2.3, 95%CI, 1.14-4.50; P=.018), and time from symptom onset to angioplasty >6hours (HR 3.2, 95%CI, 1.6-7.5; P=.001). A score was designed that included these predictive factors (score "6-ANT-40"). Survival at 1 year was 54.5% for patients with score 0, 32.3% for score 1, 27.4% for score 2 and 17% for score 3 (P=.004, c-statistic 0.70). The score was validated in an independent cohort of 124 patients, showing 1-year survival rates of 64.5%, 40.0%, 28.9%, and 22.2%, respectively (P=.008, c-statistic 0.68). Conclusions: A preprocedural score based on 3 simple clinical variables (anterior location, ejection fraction<40%, and delay time >6 hours) may be used to estimate survival after primary angioplasty in elderly patients with cardiogenic shock and to guide preinterventional decision-making

Multivessel disease in patients over 75years old with ST elevated myocardial infarction. Current management strategies and related clinical outcomes in the ESTROFA MI+75 nation-wide registry.

BACKGROUND: In elderly patients with ST elevated myocardial infarction (STEMI) and multivessel disease (MVD the outcomes related with different revascularization strategies are not well known. METHODS: Subgroup-analysis of a nation-wide registry of primary angioplasty in the elderly (ESTROFA MI+75) with 3576 patients over 75years old from 31 centers. Patients with MVD were analyzed to describe treatment approaches and 2years outcomes. RESULTS: Of 1830 (51%) with MVD, 847 (46%) underwent multivessel revascularization either in acute (51%), staged (44%) or both procedures (5%). Patients with previous myocardial infarction and those receiving drug-eluting stents or IIb-IIIa inhibitors were more prone to be revascularized, whereas older patients, females and those with Killip III-IV, renal failure and higher ejection fraction were less likely. Survival free of cardiac death and infarction at 2years was better for those undergoing multivessel PCI (85.8% vs. 80.4%, p<0.0008), regardless of Killip class. Multivessel PCI was protective of cardiac death and infarction (HR 0.60, 95% CI 0.40-0.89; p=0.011). Complete revascularization made no difference in outcomes among those patients undergoing multivessel PCI. The best prognosis corresponded to those undergoing multivessel PCI in staged procedures (p<0.001). A propensity score matching analysis (514 patients in each group) yielded similar results. CONCLUSIONS: In elderly patients with STEMI and MVD, multivessel PCI was related with better outcomes especially after staged procedures. Among those undergoing multivessel PCI, anatomically defined completeness of revascularization had not prognostic influence. SUMMARY: We sought to investigate the revascularization strategies applied and their prognostic implications in patients aged over 75years with ST elevated myocardial infarction showing multivessel disease. Of 1830 patients, 847 (46%) underwent multivessel PCI either in acute (51%), staged (44%) or both procedures (5%). Multivessel PCI was independent predictor of cardiac death and infarction with the best prognosis corresponding to those undergoing staged procedures.
