Women with physical disabilities increasingly aspire to become pregnant and bear children. Limited information about the potential interaction of their disabling conditions with pregnancy and childbirth exists to guide these women and their clinicians. ⋯ The importance of advanced planning and the utility of involving clinicians with disability-related expertise suggest that the use of integrated, interdisciplinary team approaches could promote quality care by facilitating improved planning and management. Additional clinical research is needed to provide women and their clinicians with more information on potential complications and options for labor and delivery.

Immunogenicity of an investigational hepatitis B vaccine (hepatitis B surface antigen co-administered with an immunostimulatory phosphorothioate oligodeoxyribonucleotide) in nonresponders to licensed hepatitis B vaccine.
An additional one to three doses of hepatitis B vaccine are recommended for nonresponders to an initial standard three-dose series. We compared the safety and immunogenicity of an investigational hepatitis B surface antigen vaccine (HBsAg-1018) with a phosphorothioate oligodeoxyribonucleotide adjuvant that targets toll-like receptor-9 to a commercially available, alum-adjuvanted hepatitis B vaccine (HBsAg-Eng) in nonresponders to three previous doses (primary study) or to four to six previous doses (substudy) of HBsAg-Eng. ⋯ In the substudy, a greater proportion of HBsAg-1018 recipients achieved an anti-HBs concentration ≥ 100 mIU/mL (54.5% vs. 8.3%, p = 0.027), and those responders had higher geometric mean antibody concentrations at 4 weeks (264 vs. 46.5 mIU/mL, p = 0.021) and 52 weeks (7.0 vs. 1.2 mIU/mL, p = 0.030) than HBsAg-Eng recipients. Although this study suggests that HBsAg-1018 may have improved immunogenicity in nonresponders to hepatitis B vaccine vaccination when compared with HBsAg-Eng, larger studies are required.

Immunoglobulin A nephropathy (IgAN) is a major cause of secondary hypertension (HT) of renal origin - a significant prognostic factor of IgAN. In children, similar to HT, prehypertension (pre-HT) is becoming a significant health issue. However, the role of secondary HT and pre-HT (HT/pre-HT) in the progression of pediatric IgAN remains unclear. ⋯ HT/pre-HT in pediatric IgAN patients is an important modifiable factor. A relationship is observed between HT/pre-HT and its determinants, especially segmental glomerulosclerosis. Potential therapeutic approaches for IgAN with HT/pre-HT might be directed toward the management of coagulation status, active lesions, and hemodynamics for slowing disease progression.

The authors undertook a prospective study of trauma victims in the intensive care unit (ICU) to investigate the clinical course of pneumonia and the local and systemic immune responses to the pneumonia. ⋯ Pneumonia prolonged duration of mechanical ventilation, ICU and hospital stay, and overall infectious morbidity. Although immune suppression has been recognized as a result of initial injury, the development of pneumonia coincided with the nadir of immune function. Poor outcome patients were clinically identifiable 5 days after pneumonia and immunologically identifiable within 2 days. Moreover, there was localized suppression of pulmonary leukocytes at the site of the infiltrate compared to the uninfected lobes. This same alteration was noted in experimental Klebsiella pneumoniae pneumonia. This evidence suggests that there is active immune participation within the respiratory system. It also suggests that there are predispositions to pulmonary infections, and it may allow immune modulation targeted to pulmonary leukocytes to hasten clinical recovery and minimize pulmonary dysfunction.
