Predictability of adverse outcomes in hypertensive disorders of pregnancy: a multicenter prospective cohort study.

OBJECTIVES: To explore variables associated with adverse maternal/fetal/neonatal outcomes among pregnant/postpartum patients admitted to ICU for hypertensive disorders of pregnancy (HDP). METHODS: Multicenter, prospective, national cohort study. RESULTS: Variables independently associated with maternal/fetal/neonatal mortality among 172 patients were as follows: Acute Physiology and Chronic Health Evaluation-II (APACHE-II)(OR1.20[1.06-1.35]), gestational age (OR0.698[0.59-0.82]) and aspartate aminotransferase (AST)(OR1.004[1.001-1.006]). Positive likelihood ratio for headache, epigastric pain, and visual disturbances to predict composite adverse outcomes were 1.23(1.16-1.30), 0.76(0.59-1.02), and 1.1(0.98-1.2), respectively. CONCLUSIONS: Maternal/fetal mortality due to HDP was independently associated with severity of illness on admission, gestational age, and elevated AST. Accuracy of clinical symptoms to predict composite adverse outcomes was low.

Infección extraintestinal debida a bacterias del género Campylobacter / Extraintestinal infections due to Campylobacter SPP

Campylobacter jejuni causa principalmente enteritis disenteriforme; los casos debidos a C. fetus son raros, mayormente bacteriemiaen inmunosuprimidos. Presentamos dos casos de enfermedad diarreica con bacteriemia, ambos con hemorragia digestiva,debida a C. jejuni, un caso inusual de infección de anerurisma de la arteria femoral y un caso de bacteriemia recurrente conprobable foco en marcapasos en un anciano sin otro factor de inmunosupresión, los dos últimos debidos a C. fetus. Todos lospacientes tuvieron evolución favorable. Recomendamos prestar atención a los hemocultivos que resulten positivos para efectuarlos subcultivos adecuados para recuperar, identificar y determinar la sensibilidad a los antimicrobianos de este tipo de bacterias microaerofílicas.

Campylobacter jejuni often causes enteritis; cases due to C. fetus are rare: it causes mostly bacteremia in patients with immunosuppression.We present two cases of diarrheal disease with bacteremia, both with gastrointestinal bleeding due to C. jejuni, an unusual case ofC. fetus infection of an aneurysm in the femoral artery, and one case of recurrent C. fetus bacteremia with probably focus in apacemaker in an elderly patient without another cause of immunosuppression. All patients had a favorable evolution. We recommendspecial attention to the positive blood cultures in order to recover and identify this type of microaerophilic bacteria, and determineantimicrobial susceptibility.

Characteristics, Outcomes, and Predictability of Critically Ill Obstetric Patients: A Multicenter Prospective Cohort Study.

OBJECTIVE: To evaluate pregnant/postpartum patients requiring ICUs admission in Argentina, describe characteristics of mothers and outcomes for mothers/babies, evaluate risk factors for maternal-fetal-neonatal mortality; and compare outcomes between patients admitted to public and private health sectors. DESIGN: Multicenter, prospective, national cohort study. SETTING: Twenty ICUs in Argentina (public, 8 and private, 12). PATIENTS: Pregnant/postpartum (< 42 d) patients admitted to ICU. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Three hundred sixty-two patients were recruited, 51% from the public health sector and 49% from the private. Acute Physiology and Chronic Health Evaluation II was 8 (4-12); predicted/observed mortality, 7.6%/3.6%; hospital length of stay, 7 days (5-13 d); and fetal-neonatal losses, 17%. Public versus private health sector patients: years of education, 9 ± 3 versus 15 ± 3; transferred from another hospital, 43% versus 12%; Acute Physiology and Chronic Health Evaluation II, 9 (5-13.75) versus 7 (4-9); hospital length of stay, 10 days (6-17 d) versus 6 days (4-9 d); prenatal care, 75% versus 99.4%; fetal-neonatal losses, 25% versus 9% (p = 0.000 for all); and mortality, 5.4% versus 1.7% (p = 0.09). Complications in ICU were multiple-organ dysfunction syndrome (34%), shock (28%), renal dysfunction (25%), and acute respiratory distress syndrome (20%); all predominated in the public sector. Sequential Organ Failure Assessment (during first 24 hr of admission) score of at least 6.5 presented the best discriminative power for maternal mortality. Independent predictors of maternal-fetal-neonatal mortality were Acute Physiology and Chronic Health Evaluation II, education level, prenatal care, and admission to tertiary hospitals. CONCLUSIONS: Patients spent a median of 7 days in hospital; 3.6% died. Maternal-fetal-neonatal mortality was determined not only by acuteness of illness but to social and healthcare aspects like education, prenatal control, and being cared in specialized hospitals. Sequential Organ Failure Assessment (during first 24 hr of admission), easier to calculate than Acute Physiology and Chronic Health Evaluation II, was a better predictor of maternal outcome. Evident health disparities existed between patients admitted to public versus private hospitals: the former received less prenatal care, were less educated, were more frequently transferred from other hospitals, were sicker at admission, and developed more complications; maternal and fetal-neonatal mortality were higher. These findings point to the need of redesigning healthcare services to account for these inequities.
