Design and Region-Specific Adaptation of the Dietary Intervention Used in the SODIUM-HF Trial: A Multicentre Study.

Background: Restricting dietary sodium consumption has been considered a major component of self-care management in heart failure (HF); however, the evidence supporting this recommendation has not been conclusive. The tudy f ietary ntervention nder 100 MOL in eart ailure (SODIUM-HF) trial aims to assess the effects of dietary sodium reduction on clinical outcomes in a HF population using a pragmatic design to provide empirical evidence to guide dietary sodium intake recommendations in patients with chronic HF.

Methods: SODIUM-HF is a multicentre, open-label, blinded adjudicated endpoint, randomized controlled trial in ambulatory patients with chronic HF.

[Case report. Aggressive angiomyxoma of vagina. A rare tumor diagnosed].

The case of a female patient of 35 years of age, with a pedunculated tumor dependent of the vagina, of approximately 25 x 12 x 8 cm, who had a wide resection. The report was consistent with myxoid aggressive angiomyxoma. This is a myxoid mesenchymal neoplasm of slow growth, which mainly appears in deep soft tissues of the pelvic, genital or perineal areas of adult women.

[Associated factors to extubation failure in the term newborns from a neonatal intensive care unit].

Introduction: The mechanical ventilator support (MVS) it is a procedure which improves survival of critically ill newborns (NB), but is not risk free one of them is tracheal damage reintubations by extubation failure. Knowledge that there is the medical literature is about preterm infant and there is not information about term NB.

Objective: To establish that factors are associated to the unsuccessful extubation in the term NB from 37 to 42 weeks of gestational age.

[Physician-patient with AIDS-relationship, as a model of clinical relation within the framework of the social security institutions in Mexico].

Objective: To examine the nature and level of physician involvement during a clinical encounter with a patient with a chronic condition, such as AIDS, and to explore how it is understood and constructed by them.

Material And Methods: Qualitative design with participant observation and semi-structured interviews, with physicians and patients, conducted in hospitals of Social Security Institutions in Mexico City Data were analyzed using the constant comparative method developed in the grounded theory tradition. The emergent themes studied were the dynamics of the encounters, levels of participation of the physician, and attitudes of both participants.

[Assessment of prenatal, perinatal, and postnatal factors for intraventricular hemorrage in premature newborns less than 33 weeks of gestational age].

Objective: Evaluation of risk factors for intraventricular hemorrhage in preterm less than 33 weeks gestational age (RNP).

Methods: CASE-control study. We included RNP from a tertiary care center classified by the results of transfontanellar sonography.

[Thyroid dysfunction in children with chronic renal failure].

Objectives: To determine the frequency and type of thyroid dysfunction in children with chronic renal failure (CRF) in peritoneal dialysis (PD) or hemodialysis (HD); and to establish the accuracy of the presence of goiter to identify patients with CRF and thyroid dysfunction.

Patients And Methods: This is a cross-sectional study performed in a tertiary pediatric medical care center. CRF patients younger than 17 years old, with more than three months in PD or HD were included.

[Alteplase in acute coronary syndromes].

Objective: The registry intends to establish the safety and security of one-hour 100 mg alteplase infusion and 50 mg in 30 minutes to facilitate percutaneous coronary intervention (PCI) in a cardiology hospital with primary angioplasty program (24 hours 365 days a year) with current doses of unfractionated heparin and enoxaparin.

Methods And Results: REALSICA II is a prospective registry that included 103 patients with final diagnosis of ST elevation myocardial infarction in which Alpert's quality criteria were used. Seventy two patients were under one-hour 100 mg alteplase infusion and thirty one under 30 minutes 50 mg alteplase infusion to facilitate PCI.

[Long-term results of mitral percutaneous valvuloplasty with Inoue technique. Seven-years experience at the Cardiology Hospital of the National Medical Center "Siglo XXI", IMSS].

Unlabelled: Since the last decade, percutaneous balloon mitral valvuloplasty with Inoue catheter is considered the treatment of choice for selected patients (mobile valve, no calcification and minimal subvalvular disease) with rheumatic mitral stenosis.

Objective: We present the seven-year follow-up experience of 456 patients treated with this technique in the catheter laboratory of the Cardiology Hospital in National Medical Center SXXI.

Material And Methods: It is a retrospective, transversal and observational study performed with data obtained from January 1994 and December 2000, with a follow-up of 58.

[The role of social networks in exclusive breastfeeding].

Objective: The purpose of the study was to explore the network that the social actors form around the mother with a neonate and the roles they play, either as support or as an obstacle of exclusive breast-feeding.

Material And Methods: We applied a social network survey in two stages: in the first one, we asked mothers with babies under six months of age who had helped them breast-feed their babies and who had had a bearing on not letting them do it. Later, we asked other mothers who had told them to give formula, water, tea or solid food to the babies.

[On the centennial of hormones. A tribute to Ernest H. Starling and William M. Bayliss].

Ernest H. Starling introduced the term hormone 100 years ago in his Croonian Lectures to the Royal College of Physicians in June 1905. It was demonstrated for the first time that one part of the body could influence the function of another distant part.

Drug therapy and adverse drug reactions to terbutaline in obstetric patients: a prospective cohort study in hospitalized women.

BACKGROUND: Adverse drug reactions (ADR's) could be expected more frequently in pregnant women. This study was performed in order to identify ADR's to tocolytic drugs in hospitalised pregnant women. METHODS: A prospective cohort study was performed in two General Hospitals of the Instituto Mexicano del Seguro Social (IMSS) in Mexico City.

Gnathostomosis, an emerging foodborne zoonotic disease in Acapulco, Mexico.

Between 1993 and 1997, 98 gnathostomosis cases were clinically identified in Acapulco, Mexico. Intermittent cutaneous migratory swellings were the commonest manifestation. Larvae were identified in 26 cases, while in 72, final diagnosis was made on the basis of epidemiologic data, food habits, and positive enzyme-linked immunosorbent assay and Western blot results.

Sexually transmitted diseases and related genital pathologies in oligozoospermia.

Sexually transmitted pathogens are associated with a wide range of anomalies and diseases, including recurrent genital herpes, urethritis, syphilis, prostitis, genital ulcers, perihepatitis, unexplained infertility, infant prematurity, low birth weight, and neonatal death or malformations. Prompt diagnosis of sexually transmitted diseases (STDs) is essential to ensure appropriate specific treatment and to reduce complications. Extensive studies on the etiology of male infertility include poorly treated infections such as STDs, epididymitis, complications associated with mumps, delayed treatment of undescended testes, repair of inguinal hernia, varicocele, endocrine disorders, anomalies of the reproductive tract and male accessory organs, trauma, surgery, heat-cold injury, and active-passive immunization.
