Maternal sepsis: a Scottish population-based case-control study.

OBJECTIVE: To describe the risk of maternal sepsis associated with obesity and other understudied risk factors such as operative vaginal delivery. DESIGN: Population-based, case-control study. SETTING: North NHS region of Scotland. POPULATION: All cases of pregnant, intrapartum and postpartum women with International Classification of Disease-9 codes for sepsis or severe sepsis recorded in the Aberdeen Maternal and Neonatal Databank (AMND) from 1986 to 2009. Four controls per case selected from the AMND were frequency matched on year-of-delivery. METHODS: Cases and controls were compared; significant variables from univariable regression were adjusted in a multivariable logistic regression model. MAIN OUTCOME MEASURES: Dependent variables were uncomplicated sepsis or severe ('near-miss') sepsis. Independent variables were demographic, medical and clinical delivery characteristics. Unadjusted and adjusted odds ratios (OR) with 95% confidence intervals (95% CI) are reported. RESULTS: Controlling for mode of delivery and demographic and clinical factors, obese women had twice the odds of uncomplicated sepsis (OR 2.12; 95% CI 1.14-3.89) compared with women of normal weight. Age <25 years (OR 5.15; 95% CI 2.43-10.90) and operative vaginal delivery (OR 2.20; 95% CI 1.02-4.87) were also significant predictors of sepsis. Known risk factors for maternal sepsis were also significant in this study (OR for uncomplicated and severe sepsis respectively): multiparity (OR 6.29, 12.04), anaemia (OR 3.43, 18.49), labour induction (OR 3.92 severe only), caesarean section (OR 3.23, 13.35), and preterm birth (OR 2.46 uncomplicated only). CONCLUSIONS: Obesity, operative vaginal delivery and age <25 years are significant risk factors for sepsis and should be considered in clinical obstetric care.

Vigilance must be a priority: maternal genital tract sepsis.

Although very rare in the UK, sepsis was the leading cause of direct maternal deaths during 2006-2008, with an increase in community acquired Group A streptococcal infection (CMACE 2011). Most deaths occurred in the postnatal period and were often preceded by a sore throat or other upper respiratory infection, with a clear seasonal pattern. An associated factor was women of BME origin (black or minority ethnic origin). More than half of the deaths followed birth by caesarean section. All antenatal and postnatal women should be offered advice on the signs and symptoms of life threatening conditions, including sepsis. Information should include the importance of good hand and perineal hygiene and of the need to seek immediate medical care if feeling unwell. Relevant NICE guidance should be disseminated and implemented as widely as possible. Greater priority should be given to ensuring all women, particularly those in the most vulnerable groups, are aware of how to access timely and appropriate care.

Prevalence and factors associated with postpartum vaginal infection in the Khyber Agency federally administered tribal areas, Pakistan.

OBJECTIVE: To estimate the prevalence and to identify the factors associated with vaginal infection among the married women between the ages of 15-49 years residing in the Khyber Agency (FATA), Pakistan. METHODS: A cross-sectional study was conducted in the month of July 2005 on 1084 mothers by using random sampling strategy in Khyber Agency Pakistan by trained nurses. The descriptive and multivariate statistics were computed. RESULTS: The multivariate analysis showed that the associated factors with vaginal infection were the use of unhygienic material to soak up the lochia [aOR = 3.45, 95% CI (1.36, 8.75)], bathing after 40 days [aOR = 2.10, 95% CI (1.55, 3.14)], and women who did not receive antenatal care [OR = 3.87, 95% CI (1.93, 7.75)]. Also women who did not have medical facilities available [OR = 2.45, 95% CI (1.23, 5.06)] reported of vaginal infection. CONCLUSIONS: This study concluded that there is considerable need for health education among women and the entire community for the maintenance of hygiene, safe delivery through medical personnel and improvement in the mobility of mothers and female education.

Sociocultural factors in puerperal infectious morbidity among Navajo women.

From 1980 to 1982, a sample of 968 pregnant Navajo women in New Mexico was enrolled in a prospective study of biologic and sociocultural factors in puerperal infectious morbidity. Past studies have independently implicated both genital infection and psychosocial stressors in perinatal complications, but, to the authors' knowledge, no previous work has concurrently investigated the interactive effects of genital pathogens and psychosocial processes. Endocervical cultures for Mycoplasma hominis and Chlamydia trachomatis were obtained during prenatal visits, and structured interviews were conducted assessing social support and the degree of cultural traditionality, in this context a proxy measure of acculturative stress. The incidences of postpartum fever, endometritis, and premature rupture of membranes were significantly associated with the concurrence of two factors: the presence of genital tract M. hominis and a highly traditional cultural orientation. When demographic and conventional obstetric risk factors were controlled for, women with both M. hominis and high traditionality experienced infectious complications at a rate twice that of women with either factor alone. Among the plausible explanations for this result is the possibility that acculturative stress undermines physiologic resistance to infectious genital tract disease.
