Reversión del síndrome metabólico por el consumo de ácidos grasos poliinsaturados / Metabolic syndrome reversion by polyunsaturated fatty acids ingestion

Fundamento y objetivo: La frecuencia del síndrome metabólico (SM) está creciendo y la dieta tiene una importante influencia en su evolución. Nuestro objetivo fue estudiar el efecto de 3 fuentes de ácidos grasos poliinsaturados sobre los parámetros del SM en humanos. Pacientes y método: Se diagnosticó SM según la Federación Internacional de Diabetes. Se asignaron cuasialeatoriamente 3 grupos de individuos (n = 15/grupo) a uno de los siguientes tratamientos durante 6 semanas: a) 1,8 g/d n-3 (1,08 g ácido eicosapentanoico + 0,72 g ácido docosahexanoico); b) 2,0 g/d conjugated linoleic acid (CLA, «ácido linoleico conjugado») (50:50, cis9:trans11, trans10:cis12), y c) 40 g/d nuez de Castilla. Los parámetros clínicos y bioquímicos se evaluaron antes y después del ensayo. Resultados: En el grupo con n-3 el nivel de triglicéridos disminuyó de 183,9 ± 35,2 mg/dl a 149,6 ± 29,0 mg/dl (p = 0,007). En el grupo con nuez de Castilla la concentración de HDL aumentó de 41,7 ± 5,2 mg/dl a 47,8 ± 5,4 mg/dl (p = 0,004) y el índice de Castelli (colesterol total/c-HDL) disminuyó de 4,86 ± 0,97 a 3,82 ± 0,81 (p = 0,004). No hubo cambios significativos en el grupo con CLA. Al final del ensayo, el 46,7% del grupo con nuez de castilla, el 46,7% del grupo con n-3 y el 20% del grupo con CLA se observaron sin SM. Conclusiones: Los grupos que consumieron ácidos grasos poliinsaturados n-3 y los contenidos en la nuez de castilla en dosis diarias moderadas durante 6 semanas mejoraron el componente dislipidemia del SM, hipertrigliceridemia y nivel bajo de HDL (AU)

Background and objective: Metabolic syndrome (MS) frequency is growing and diet has an important influence on its evolution. Our objective was to study the effect of 3 sources of polyunsaturated fatty acids on MS parameters in humans. Patients and method: The MS was diagnosed according to the International Diabetes Federation. Three groups of individuals (n = 15/group) were quasi-randomly assigned to one of the following treatments during 6 weeks: a) 1.8 g/d n-3 (1.08 g eicosapentoaenoic acid + 0.72 g docosahexaenoic acid); b) 2.0 g/d conjugated linoleic acid (CLA, 50:50, cis9:trans11, trans10:cis12), and c) 40 g/d walnut. The clinical and biochemical parameters were evaluated at the beginning and the end of the essay. Results: In the group with n-3 the triglycerides level decreased from 183.9 ± 35.2 mg/dl to 149.6 ± 29.0 mg/dl (P = .007). In the group with walnut the HDL level rose from 41.7 ± 5.2 mg/dl to 47.8 ± 5.4 mg/dl (P = .004) and the Castelli index (total cholesterol/HDL) decreased from 4.86 ± 0.97 to 3.82 ± 0.81 (P = .004). There were not significant changes in the CLA group. At the end of the essay, 46.7% of walnut group patients, 46.7% of n-3 group and 20% of CLA group, had no MS. Conclusions: The groups that consumed polyunsaturated fatty acids n-3 and those in walnut in moderate daily doses during 6 weeks had an improvement of the dyslipidemia component of MS, hypertriglyceridemia and low HDL level (AU)

[Perinatal hospital mortality: its relationship with prenatal care quality]. / Mortalidad perinatal hospitalaria y su relación con la calidad de la atención prenatal.

OBJECTIVE: Our aim was to analyze infant mortality at the Mexican Institute of Social Security (IMSS) North Veracruz, Mexico, Delegation from the perspective of prenatal care quality. MATERIALS AND METHODS: We performed a retrospective case-control study and included all cases of perinatal mortality at the IMSS at North Veracruz from July 1 to December 31, 2003. There were two controls per case matched by gender and date of birth. Prenatal care quality was evaluated by a specifically developed questionnaire. RESULTS: A total of 53 cases were used for the final analysis. Maternal age was similar between cases and controls (p = 0.814). There were fewer prenatal appointments (p = 0.0001), fewer test performed [blood test (p = 0.0001) and urine test (p = 0.004)], higher obstetric risk (p = 0.004), and fewer obstetric ultrasound imaging studies developed (p = 0.022) in cases of perinatal mortality vs. controls. Main variables related with perinatal mortality were the following: absent of blood test (odds ratio [OR] 4.7, 95% confidence interval [Cl 95%] 2.2-9.9, p = 0.0001); urine test (OR 4.4, CI 95% 1.5-12.6, p = 0.004), and obstetric ultrasound studies (OR 2.3, Cl 95%, 1.1-4.8, p = 0.022), and having fewer than five prenatal appointments (OR 2.2, Cl 95% 1.1-4.4, p = 0.018). CONCLUSIONS: There is evidence of inadequate prenatal care quality in cases of hospital perinatal mortality in Veracruz. Absence of obstetric ultrasound imaging studies and blood tests during prenatal care increases the risk of perinatal mortality 2-4 times.
