Background: In the light of the ongoing debate about lowering the cut-off for acceptable blood lead level to <5 μg/dL from the currently recommended level of <10 μg/dL, we considered whether prenatal exposure to varying levels of lead is associated with similar or disparate effects on neonatal behavior. Methods: Using Brazeltons Neonatal Behavioral Assessment Scale (NBAS), an epidemiological approach and robust statistical techniques like multivariate linear regression, logistic regression, Poisson regression and structural equations modeling analyses we estimated the simultaneous indirect effects of umbilical cord blood lead (CBL) levels and other neonatal covariates on the NBAS clusters. Results: We observed that when analyzed in all study subjects, the CBL levels independently and strongly influenced autonomic stability and abnormal reflexes clusters. However, when the analysis was restricted to neonates with CBL <10 μg/dL, CBL levels strongly influenced the range of state, motor and autonomic stability clusters. Abnormal walking reflex was consistently associated with an increased CBL level irrespective of the cut-off for CBL, however, only at the lower cut-offs were the predominantly behavioral effects of CBL discernible. Conclusion: Our results further endorse the need to be cognizant of the detrimental effects of blood lead on neonates even at a low-dose prenatal exposure.

Loss of lag-response curvilinearity of indices of heart rate variability in congestive heart failure

Background: Heart rate variability (HRV) is known to be impaired in patients with congestive heart failure (CHF). Time-domain analysis of ECG signals traditionally relies heavily on linear indices of an essentially non-linear phenomenon. Poincaré plots are commonly used to study non-linear behavior of physiologic signals. Lagged Poincaré plots incorporate autocovariance information and analysis of Poincaré plots for various lags can provide interesting insights into the autonomic control of the heart. Methods: Using Poincaré plot analysis, we assessed whether the relation of the lag between heart beats and HRV is altered in CHF. We studied the influence of lag on estimates of Poincaré plot indices for various lengths of beat sequence in a public domain data set (PhysioNet) of 29 subjects with CHF and 54 subjects with normal sinus rhythm. Results: A curvilinear association was observed between lag and Poincaré plot indices (SD1, SD2,SDLD and SD1/SD2 ratio) in normal subjects even for a small sequence of 50 beats (p value for quadratic term 3 × 10-5, 0.002, 3.5 × 10-5 and 0.0003, respectively). This curvilinearity was lost in patients with CHF even after exploring sequences up to 50,000 beats (p values for quadratic term > 0.5). Conclusion: Since lagged Poincaré plots incorporate autocovariance information, these analyses provide insights into the autonomic control of heart rate that is influenced by the non-linearity of the signal. The differences in lag-response in CHF patients and normal subjects exist even in the face of the treatment received by the CHF patients.

Bias-corrected diagnostic performance of the naked eye single tube red cell osmotic fragility test (NESTROFT): An effective screening tool for ß-thalassemia

Background: It is being increasingly recognized that a majority of the countries in the thalassemia-belt need a cost-effective screening program as the first step towards control of thalassemia. Although the naked eye single tube red cell osmotic fragility test (NESTROFT) has been considered to be a very effective screening tool for b-thalassemia trait, assessment of its diagnostic performance has been affected with the reference test- and verification-bias. Here, we set out to provide estimates of sensitivity and specificity of NESTROFT corrected for these potential biases.We conducted a cross-sectional diagnostic test evaluation study using data from 1563 subjects from Central India with a high prevalence of b-thalassemia. We used latent class modelling after ensuring its validity to account for the reference test bias and global sensitivity analysis to control the verification bias. We also compared the results of latent class modelling with those of five discriminant indexes. We observed that across a range of cut-offs for the mean corpuscular volume (MCV) and the hemoglobin A2 (HbA2) concentration the average sensitivity and specificity of NESTROFT obtained from latent class modelling was 99.8 and 83.7%, respectively. These estimates were comparable to those characterizing the diagnostic performance of HbA2, which is considered by many as the reference test to detect b-thalassemia. After correction for the verification bias these estimates were 93.4 and 97.2%, respectively. Combined with the inexpensive and quick disposition of NESTROFT, these results strongly support its candidature as a screening tool—especially in the resource-poor and high-prevalence settings.

Predictive Performance of Anthropometric Indexes of Central Obesity for the Risk of Type 2 Diabetes

3 July, 2014 Publications

.

Download Paper


Background: In spite of several available anthropometric indexes, the relative merit of these indexes for the prediction of type 2 diabetes remains unknown. Considering that obesity and diabetes commonly coexist as co-morbidities, our objective was to directly compare the performance of measures of central and general obesity to predict the risk of type 2 diabetes. Methods. We conducted a case-control study of type 2 diabetes on 150 cases and 150 age- and gender-matched controls. We directly compared the predictive performance of five anthropometric indexes: four related to central obesity—waist circumference (WC), waist/hip ratio (WHR), abdominal volume index (AVI) and conicity index (CI); and one related to general obesity—body mass index (BMI).We used various statistical approaches like area under (AUC) receiver-operating characteristic (ROC) curves, likelihood ratios, logistic regression and Shannon’s entropy to compare the performance of the indexes in the study sample as well as bootstrapped samples. Results. WC had the highest overall predictive accuracy that was gender insensitive (AUC 0.77 in males and 0.74 in females); a comparable information content as that of AVI (Shannon’s entropy  1.81 for WC and 1.84 for AVI) and was a better predictor of the risk of type 2 diabetes than all the remaining indexes. WC also correlated strongly with the biochemical markers of diabetes like blood sugar and lipid profile. Conclusions. WC is a simple, non-invasive and accurate predictor of the risk of type 2 diabetes that can potentially be used in screening programs in developing countries.

Platelet distribution width (PDW) is increased in vaso-occlusive crisis in sickle cell disease.

Download Paper


Background: Considering the multigenic and multifactorial nature of the disease, we argue that a generalized bone marrow hyperplasia—and not merely erythroid hyperplasia—will occur in sickle cell disease. Consequently, we expect the hematological parameters to depict erythroid, myeloid as well as megakaryocyte hyperplasia. In the light of this expectation, we hypothesized that platelet distribution width (PDW) will increase in sickle cell disease. Here, we report the results from a cross-sectional study of 216 children admitted with complaints suggestive of vaso-occlusive crisis. We observed a strong association between PDW and sickle cell disease as compared to children who had HbAA genotype. Our findings bridge previous inconsistencies relating to the role of platelets in sickle cell disease. Implications of this finding are discussed. Ann Hematol. 2004;83:331-5.

LMRF is working since 5 years in 20 PHCs stated as 10 control and 10 Intervention Clusters in four districts of Maharashtra i.e.

  • Nagpur
  • Bhandara
  • Wardha
  • Chandrapur

These Clusters were selected due to their low geographic area, higher number of Infant, Neonatal and Maternal Mortality ratio, poor facility services and delayed in seeking healthcare facilities and also due to lack of health Problem awareness.
