Magnitude and Factors Associated with Child Abuse in a Mega City of Developing Country Pakistan

Objective

Child abuse is one of the major challenges for health care providers. This study was conducted to determine the burden of child abuse (physical & emotional) and the factors associated with it in an urban city of Pakistan.

Methods

This cross-sectional study was conducted in primary care clinics affiliated with a tertiary care hospital in Karachi, Pakistan between March to December 2010. Mothers with children aged between 6 and 12 years were included in the study. Those mothers’ suffering from any acute illness like high grade fever, were excluded. A total of 412 mothers were recruited through consecutive sampling and written informed consent was taken. A pre-tested questionnaire was used to seek information about child abuse. Data was analyzed using SPSS version 19 and multivariable logistic regression was used to identify the factors (age, gender of child, family structure, educational status of parents, and mother’s perception of her home environment) associated with child abuse.

Findings

Of the total 412 mothers, final analysis was conducted on 379 mothers. In all, 32.5% of children had been abused, 25.5% physically and 17.9% emotionally. Abuse was reported more among children whose mothers had minimal or no schooling (P=0.02), who were abused by their husbands (P<0.001), not satisfied with their marital life (P<0.001), and stressful home environment (P=0.02). In the multivariate analysis, the factors found to be independently associated with child abuse were mothers abused by their husbands (AOR=4.2; 95%CI: 2.2–7.9) and child being a girl (AOR=8.7; 95%CI: 4.5–16.8).

Conclusion

The prevention of child abuse can be achieved through comprehensive, multifaceted and integrated approaches requiring joint efforts by the government, policy makers, stake holders, social workers, educationists, and public health practitioners.     

Rare,Protein-Altering Variants in AS3MT and Arsenic Metabolism Efficiency: A Multi-Population Association Study

Background: Common genetic variation in the arsenic methyltransferase (AS3MT) gene region is known to be associated with arsenic metabolism efficiency (AME), measured as the percentage of dimethylarsinic acid (DMA%) in the urine. Rare, protein-altering variants in AS3MT could have even larger effects on AME, but their contribution to AME has not been investigated.Objectives: We estimated the impact of rare, protein-coding variation in AS3MT on AME using a multi-population approach to facilitate the discovery of population-specific and shared causal rare variants.Methods: We generated targeted DNA sequencing data for the coding regions of AS3MT for three arsenic-exposed cohorts with existing data on arsenic species measured in urine: Health Effects of Arsenic Longitudinal Study (HEALS, n=2,434), Strong Heart Study (SHS, n=868), and New Hampshire Skin Cancer Study (NHSCS, n=666). We assessed the collective effects of rare (allele frequency <1%), protein-altering AS3MT variants on DMA%, using multiple approaches, including a test of the association between rare allele carrier status (yes/no) and DMA% using linear regression (adjusted for common variants in 10q24.32 region, age, sex, and population structure).Results: We identified 23 carriers of rare-protein-altering AS3MT variant across all cohorts (13 in HEALS and 5 in both SHS and NHSCS), including 6 carriers of predicted loss-of-function variants. DMA% was 6–10% lower in carriers compared with noncarriers in HEALS [β=−9.4 (95% CI: −13.9, −4.8)], SHS [β=−6.9 (95% CI: −13.6, −0.2)], and NHSCS [β=−8.7 (95% CI: −15.6, −2.2)]. In meta-analyses across cohorts, DMA% was 8.7% lower in carriers [β=−8.7 (95% CI: −11.9, −5.4)].Discussion: Rare, protein-altering variants in AS3MT were associated with lower mean DMA%, an indicator of reduced AME. Although a small percentage of the population (0.5–0.7%) carry these variants, they are associated with a 6–10% decrease in DMA% that is consistent across multiple ancestral and environmental backgrounds. https://doi.org/10.1289/EHP8152     

Response of First-Line Antibiotic Therapy in Patients with Febrile Neutropenia During Treatment of Hematological Disorders

Patients with hematological disorders develop febrile neutropenia (FN); most of these events remain undetermined in origin. We performed a prospective study to determine the microbiological characteristics of infections and their response to the first-line antibiotic therapy in FN. The study was conducted at National Institute of Blood Disease and Bone Marrow Transplant. Two-hundred episodes of FN were assessed for the bacterial growth, antimicrobial susceptibility pattern and response to the first-line treatment of FN. All patients were given Ceftazidime and Amikacin Bosch Pharmaceutical (Pvt. Ltd), as first-line antibiotic in FN. Out of 200 episodes we had 108 clinically and microbiologically documented infections. The isolated frequencies for gram negative and gram positive organisms were n = 52 and 49 (48 and 45 %) respectively. Among gram negative micro-organisms, Escherichia coli (E. coli) was isolated in 15 (28.8 %), Klebsiella pneumonae in 4 (7.6 %) and Pseudomonas aeruginosa in 10 (19.2 %) were in highest frequencies. Methicillin sensitive staphylococci emerged as the frequently isolated gram-positive bacteria. Eight-one episodes (45.3 %) responded to the first-line treatment and death reported in 20 cases (10 %). Our study showed almost equal trend of gram positive and gram negative bacteria isolated from patients suffering from neutropenic fever. Empirical use of Ceftazidime and Amikacin as first-line antibiotics was able to cover the infection only in 45.3 % of episodes suffering from FN.

Preliminary safety evaluation of a taurocholate‐conjugated low‐molecular‐weight heparin derivative (LHT7): a potent angiogenesis inhibitor

In our previous studies, taurocholic acid (TA)‐conjugated low‐molecular‐weight heparin derivative (LHT7) has been proven to be a potent anti‐angiogenic agent by demonstrated successful blockage capability of vascular endothelial growth factors (VEGF). Preliminary safety evaluations were conducted based on its mechanism of action and chemical behavior. For this purpose, acute toxicity study, and hematological and serological evaluations were carried out. Additionally, in order to evaluate mechanism‐related side effects, both blood pressure and the occurrence of proteinuria were measured using a treatment regime of multiple high doses of LHT7 in a biodistribution study. LD₅₀ values for LHT7 in female and male mice were 56.9 and 64.7 mg kg^–1 doses, respectively. There were no vital fluctuations in the serological and hematological parameters, except for the elevated levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) at 100 and 200 mg kg^–1 doses of LHT7, representing vital changes in the liver function. Moreover, the results of mechanism‐related studies showed that blood pressure at 50 mg kg^–1 did not change but showed elevated levels of protein in urine. In the biodistribution study, a slight accumulation of LHT7 in the kidney and the liver were observed at the 50 mg kg^–1 repeated dose owing to the presence of bile acid. No fatal damage was observed in this study; most observations were related to the chemical composition or the mechanism of action of the material. Copyright © 2014 John Wiley & Sons, Ltd.     

Racial/Ethnic Differences in the Association between Arrest and Unprotected Anal Sex among Young Men Who Have Sex with Men: The P18 Cohort Study

This analysis aimed to determine whether the relationship between a history of arrest and unprotected anal sex (UAS) is the same for Black/Latino gay, bisexual, and other young men who have sex with men (YMSM) as compared to White/Asian/Pacific Islander (API) YMSM in New York City (NYC). Baseline audio-computer-assisted self-interview (ACASI) and interviewer-administered survey data from a sample of 576 YMSM aged 18–19 years old who self-reported being HIV-negative were analyzed. Data included history of arrest and incarceration as well as UAS in the past 30 days. Race/ethnicity was an effect modifier of the association between arrest and UAS among YMSM: White/API YMSM with a lifetime arrest history were more than three times as likely to report UAS, and Black/Latino YMSM with a lifetime history of arrest were approximately 70 % less likely to report UAS as compared with White/API YMSM with no reported arrest history. Race/ethnicity may modify the relationship between arrest and sexual risk behavior because the etiology of arrest differs by race, as partially evidenced by racial/ethnic disparities in police stop, arrest, and incarceration rates in NYC. Arrest could not only be an indicator of risky behavior for White/API YMSM but also an indicator of discrimination for Black/Latino YMSM. Further research is needed to assess whether the differential associations observed here vis-à-vis race/ethnicity are robust across different populations and different health outcomes.     

Intracranial haemorrhage in typhoid fever

Intracranial haemorrhage in typhoid fever is very rare. We report another case of non-traumatic intracranial hemorrhage in a 6-year-old boy suffering from typhoid fever, unconsciousness, seizure and non-coherent speech. Investigations revealed severe thrombocytopenia and prolonged prothrombin time. CT scan of brain showed intraparenchymal haemorrhage in frontal regions bilaterally with perilesional oedema, subarachnoid bleed and extension into the lateral ventricles. No aneurysm or arterio-venous malformation was seen on MR angiography. The patient recovered without any neurological deficit.
