RESUMEN

In low-income countries, perinatal depression is common, but longitudinal data on its influence on child health are rare. We examined the association between maternal depression and febrile illness in children. There were 654 mother/child dyads in Ghana and Côte d'Ivoire that were enrolled in a prospective birth cohort in 2010-2011 and underwent 2-years of follow up. Mothers were examined for depression using the Patient Health Questionnaire depression module antepartum and 3 and 12 months postpartum. The hazard of febrile illness in children of depressed and nondepressed mothers was estimated using a recurrent event Cox proportional hazards model. The prevalences of antepartum depression in mothers from Côte d'Ivoire and Ghana were 28.3% and 26.3%, respectively. The prevalences of depression at 3 and 12 months postpartum were 11.8% and 16.1% (Côte d'Ivoire) and 8.9% and 7.2% (Ghana). The crude and adjusted (for country and socioeconomic status) hazard ratios of febrile illness in children of depressed mothers compared with those in children of nondepressed mothers were 1.57 (95% confidence interval: 1.20, 2.07) and 1.32 (95% confidence interval: 1.01, 1.74) respectively. Perinatal depression was frequent and associated with febrile illness in the offspring. Our results showed that a high prevalence of depression in sub-Saharan Africa may pose a serious public health threat to women and their offspring.

RESUMEN

BACKGROUND: Impaired bone structure poses a challenge for the treatment of osteoporotic tibial plateau fractures. As knowledge of region-specific structural bone alterations is a prerequisite to achieving successful long-term fixation, the aim of the current study was to characterize tibial plateau bone structure in patients with osteoporosis and the elderly. METHODS: Histomorphometric parameters were assessed by high-resolution peripheral quantitative computed tomography (HR-pQCT) in 21 proximal tibiae from females with postmenopausal osteoporosis (mean age: 84.3 ±â€¯4.9 years) and eight female healthy controls (45.5 ±â€¯6.9 years). To visualize region-specific structural bony alterations with age, the bone mineral density (Hounsfield units) was additionally analyzed in 168 human proximal tibiae. Statistical analysis was based on evolutionary learning using globally optimal regression trees. RESULTS: Bone structure deterioration of the tibial plateau due to osteoporosis was region-specific. Compared to healthy controls (20.5 ±â€¯4.7%) the greatest decrease in bone volume fraction was found in the medio-medial segments (9.2 ±â€¯3.5%, p < 0.001). The lowest bone volume was found in central segments (tibial spine). Trabecular connectivity was severely reduced. Importantly, in the anterior and posterior 25% of the lateral and medial tibial plateaux, trabecular support and subchondral cortical bone thickness itself were also reduced. CONCLUSION: Thinning of subchondral cortical bone and marked bone loss in the anterior and posterior 25% of the tibial plateau should require special attention when osteoporotic patients require fracture fixation of the posterior segments. This knowledge may help to improve the long-term, fracture-specific fixation of complex tibial plateau fractures in osteoporosis.
