Background: Despite treatment, many dogs still die of complications related to canine parvoviral (CPV) enteritis. Effective prognostication would be beneficial in managing this disease.Hypothesis: We hypothesize that the occurrence of leukocytopenias at admission and at 24 and 48 hours after admission, and changes in absolute leukocyte counts over time, could be used to predict outcome.Animals: Sixty-two puppies with confirmed CPV. Methods: A prospective study was performed. CBC was performed daily until discharge or death (in which case a postmortem examination was performed).Results: Of the nonsurvivors (10/62; 16%), 9 died because of complications of the disease and 1 was euthanized because of a poor prognosis. There was a statistical significant difference in the occurrence of leukocytopenias between groups at 24 and 48 hours postadmission. The survivors showed a significant increase over time in certain leukocyte types (specifically lymphocytes) compared with values at admission. The positive predictive value for survivors was high. Nonsurvivors had marked thymic and lymphoid atrophy and marked bone marrow hypocellularity.Conclusion: An accurate prognosis could be obtained at 24 hours after admission by evaluating the change in total leukocyte, band neutrophil, lymphocyte, monocyte, and eosinophil counts.
Aims The human immunodeficiency virus (HIV) potentially causes a significant encephalopathy and resultant developmental delay in infected children. The aim of this study was to determine whether a home‐based intervention programme could have an impact on the neurodevelopmental status of children infected with HIV.
Method A longitudinal, randomized, controlled trial was conducted. A total of 122 children aged less than 2 years 6 months were assigned to either a comparison or an experimental group. Children in the experimental group were given a home stimulation programme that was updated every 3 months. The home programme included activities to promote motor, cognitive, and speech and language development. Children in the comparison group received no developmental intervention. Children were assessed by a blinded assessor at baseline, 6 months, and 12 months using the Bayley Scales of Infant Development, 2nd edition.
Results The children in this study came from poor socioeconomic backgrounds and their nutritional status was suboptimal. The experimental group included 60 children (30 males, 30 females) with a mean age of 18 months (SD 8.1mo). The comparison group included 62 children (32 males, 30 females) with a mean age 19 months (SD 8.2mo). Cognitive and motor development were severely affected at baseline, with 52% of the children having severe cognitive delay and 72% having severe motor delay at baseline. Children in the experimental group showed significantly greater improvement in cognitive (p=0.010) and motor (p=0.020) development over time than children in the comparison group.
Interpretation A home stimulation programme taught to the caregiver can significantly improve cognitive and motor development in young children infected with HIV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
