Hematological Indices for Identifying Adverse Outcomes in Children Admitted to Pediatric ICUs.

BACKGROUND: The pediatric ICU (PICU) is a specialized area where critically sick children are managed. The mortality rates in PICUs are higher in developing countries as compared to developed nations. Many of these deaths could be prevented if very sick children were identified soon after they arrived at the health facility. Hematological indices like platelet lymphocyte ratio (PLR) and neutrophil-lymphocyte ratio (NLR) have been frequently used in adults as indicators of mortality. However, their use in the pediatric population is limited due to a lack of validated reference intervals. OBJECTIVE: The objective of the study is to assess the role of hematological indices in identifying adverse outcomes in terms of mortality in children admitted to the PICU. MATERIALS AND METHODS: It is a prospective, observational study done at a tertiary care hospital. All children aged one year to 12 years admitted to the PICU were enrolled in the study. A sample for complete blood count was taken within one hour of admission to the PICU. Children who had received blood products in the last two months, those on chronic medications (>two weeks) that can affect bone marrow cellularity, and known cases of hematological disorders such as megaloblastic anemia, hematological malignancies, immune thrombocytopenia, and aplastic anemia were excluded from the study. PLR, NLR, and platelets to mean platelet volume ratio (PLT/MPV) were determined and compared among the survivors and non-survivors. RESULTS:  Out of 275 enrolled patients, 119 (43.3%) patients expired during the study period. While PLR had high sensitivity and NLR had high specificity (85.71% and 92.31%, respectively) for predicting mortality, none of these parameters had a good area under the curve (AUC) in our study. PLT/MPV of ≥32 had a sensitivity of 39.5% and a specificity of 56.41% for predicting mortality. CONCLUSIONS: Hematological parameters have been used across the world to predict ICU mortality. PLR and NLR are simple hematological biomarkers, easy to calculate, and cost-effective, and ratios are better than individual parameters. More studies and stratified samples are required to evaluate the role of hematological markers in identifying the risk of mortality in children admitted to PICUs.

Early Total Versus Gradually Advanced Enteral Nutrition in Stable Very-Low-Birth-Weight Preterm Neonates: A Randomized, Controlled Trial.

OBJECTIVE: To assess whether early total enteral nutrition (80 mL/kg/d) started on day 1 of life in hemodynamically stable preterm very-low-birth-weight (VLBW) neonates with the rapid advancement of feeds (20 mL/kg/d) help in the earlier achievement of full feeds (180 mL/kg/d). METHODS: Early total enteral nutrition (intervention) group feeding was started with 80 mL/kg/d on the first day in all hemodynamically stable neonates admitted with birth weight of 1000-1499 grams, born at 29-33 wk of gestation as determined by first-trimester ultrasonography (USG) or expanded New Ballard Score (NBS) and was advanced by 20 mL/kg/d until maximum feeds of 180 mL/kg/d were achieved; while in control group feeding was started with 30 mL/kg/d on the first day and was advanced by 20 mL/kg/d until maximum feeds were achieved. Primary outcome measure was time taken to achieve full feeds; secondary outcomes were duration of hospital stay, necrotizing enterocolitis (NEC), time to regain birth weight, duration of antibiotics, and death. RESULTS: Sixty VLBW neonates (1000-1499 g) with comparable baseline demographics were randomized within 24 h of admission to two groups. Early total enteral nutrition intervention group (group I, n = 31) achieved the target of full enteral nutrition at median 6 d; IQR: 0 to 7.8 d, a significantly shorter time compared to the controls (n = 29) (median 10 d; IQR: 9 to 11.0 d; p = < 0.05). CONCLUSION: Early total enteral nutrition started from the first day of life results in significantly less time to achieve full feeds in hemodynamically stable preterm and VLBW infants.

Recurrent arthritis: an unusual diagnosis.

Musculoskeletal complaints may be the initial manifestation of childhood leukaemias. When these symptoms predominate at the onset, a diagnosis of one of several rheumatic diseases may be entertained. Where blood tests are normal, no bone marrow examination would normally be indicated. The use of immune-suppressing medication, such as steroids, may lead to diagnostic delay or misdiagnosis.
