Improving Health Outcomes for Immigrant Families Through IPV Screening: Resources and Recommendations for Pediatric Health Care Providers

Intimate partner violence (IPV) is a significant yet preventable public health problem affecting 1 in 15 children annually. Children exposed to IPV exhibit lifelong consequences including increased risks of social, emotional, psychological and behavioral problems (mood and anxiety disorders, post-traumatic stress disorders, substance abuse, and school-related problems). Limited research exists in identifying and assessing gaps in IPV screening and surveillance techniques for vulnerable populations such as immigrants, refugees, or in families where English is not spoken in the home. The U.S. Department of Health and Human Services recommends IPV screening and counseling as part of pediatric office visits, without providing culturally appropriate tools for use. The nature of the patient-physician relationship and opportunities for intervention occurring during well child visits uniquely positions pediatric health care providers to identify and provide support for IPV victims and children. IPV screening should be routine, culturally appropriate, administered to all caregivers and all providers should be trained in surveilling and screening for IPV in immigrant and vulnerable populations.

Genetic diversity of Chilli veinal mottle virus infecting different chilli landraces in North East India indicates the possibility of transboundary movement of virus

Diverse chilli genetic resources of North East India occupy a unique niche in the Nation's chilli gene pool. Widely cultivated chilli landraces (King chilli: Capsicum chinense, bird eye chilli: Capsicum frutescens and Capsicum annuum) of North East India in general and Manipur in particular suffer from decline complex due to high incidence of viral diseases. With this background and the known prominent distribution of Chilli veinal mottle virus (ChiVMV) in Asian region, we studied its prevalence and association with diverse symptoms of chilli landraces. Molecular indexing of samples from 40 chilli plantation groves of Manipur using reverse transcription (RT)-PCR targeting the coat protein (CP) region of ChiVMV genome revealed a high incidence and wide prevalence. Out of a total of 127 chilli samples collected from different groves of Manipur, 81 chilli samples (63.78%) were positive for ChiVMV. Interestingly, ChiVMV infection rate was comparatively higher in the hilly groves (69.23% samples positive) compared to the valley groves (60% samples positive). Present study through the extensive surveys and molecular indexing work, conclusively reported the association of ChiVMV with diverse symptoms like cupping of leaf lamina with mottling, vein banding and puckering in different chilli landraces. Further, five representative ChiVMV isolates sampled from different groves of Manipur upon mechanical inoculation showed significant variation in symptom expression, indicating wide pathogenic diversity among them. Partial coat protein (CP) sequence analysis of five ChiVMV isolates from Manipur although indicated genetic homogeneity among them, but distinctiveness from ChiVMV isolates reported from the other parts of India. Phylogenetic clustering of ChiVMV isolates from Manipur near Chinese isolates rather than other Indian isolates suggested the possibility of transboundary movement.

Prospective glioma grading using single-dose dynamic contrast-enhanced perfusion MRI

AIM

To evaluate the sensitivity and specificity of single-dose dynamic contrast-enhanced (DCE) perfusion magnetic resonance imaging (MRI) in prospective evaluation of glioma grading and to correlate the relative cerebral blood volume (rCBV) values with mitotic and ki-67 indexes obtained at histopathology.

MATERIALS AND METHODS

A total of 53 histologically proven patients with glioma were included in this study. DCE-MRI perfusion with a single dose of contrast medium was included in brain tumour protocol and prospective grading of glioma into low and high grade was done based on a previously reported rCBV cut-off value of 3. Tumours with rCBV ≥ 3 were considered to be high grade and rCBV < 3 were considered to be low grade. The sensitivity and specificity of the cut-off value were estimated. Ki-67 and mitotic indexes were also obtained on histopathological analysis along with histological grading.

RESULTS

Based on pre-defined rCBV cut-off values, prospective grading of low- and high-grade glioma was achieved with a sensitivity and specificity of 97.22% and 100%, respectively. Significant correlation was found between the mitotic/ki-67 indexes and rCBV values when data for high- and low-grade tumours was combined.

CONCLUSION

DCE-MRI performed with a single dose of contrast medium is as effective as a protocol with a double-dose of contrast medium for glioma grading using 3 T MRI and could be added to the routine evaluation protocol of brain tumours.

Indigenous traditional knowledge and usage of folk bio-medicines among Rongmei tribe of Tamenglong district of Manipur, India

BACKGROUND

Rongmei tribe (Kooki), are inhabitant of the Charoi Chagotlong village, Tupul, Tamenglong district of Manipur have the traditional knowledge of folk bio-medicine based on diverse plant species for the prevention and cure of certain chronic diseases. The aim of this study was to document and preserve the indigenous knowledge of the Rongmei tribe on folk medicines.

MATERIAL AND METHODS

The present work was based on methodical field survey conducted between 2010, to 2013. Local people of within 30-70 age groups of both sexes were interviewed and a group discussion (using a structured interview schedule), was held to know about the type of plant parts used in folk bio-medicines, and their mode of use. The interviewers were drawn from a wide array of disciplines (Vendors, Farmers club, NGO's, scientific societies, etc.), to obtain maximum information in relation to folk bio-medicine.

RESULTS

A total of 60 species belonging to 36 different families (ranging from gymnosperm to angiosperm with medicinal benefits), were discussed briefly with significant emphasis on their local name, scientific name, family, parts used; they claimed to cure various ailments from these plants in this mode of folk bio-medicine. The different plant parts used were leaves, fruits, bulbs, bark, roots, seeds, tuber, trunk, flower, shoot, whole plant, rhizome, stem, wood and berries. Based on a life form of the reported plants comprise herbs, shrubs, trees, grasses, bulb, vine, climber, tuber and succulent.

CONCLUSION

Efforts should be made to promote the use of traditional biomedicines within rural communities to preserve the traditional knowledge.

Unilateral nevoid telangiectasia syndrome (UNTS) associated with chronic hepatitis C virus and positive immunoreactivity for VEGF

Unilateral Nevoid Telangectasia Syndrome (UNTS) is characterized by superficial telangiectasias in a unilateral distribution. Vascular endothelial growth factor (VEGF) may play a role in the pathogenesis of UNTS in patients with underlying hepatic disease. We report a case of a patient with UNTS accompanied by chronic hepatitis C virus infection, with a normal serum estrogen profile and strong positive immunohistochemical staining of lesional skin with VEGF.

Synthesis and characterization of certain photocrosslinkable thermotropic liquid crystalline random copolyesters containing arylidene moiety

A new series of 12 thermotropic liquid crystalline and photocrosslinkable random copolyesters were synthesized from terephthalic acid, isophthalic acid and 4,4'-oxybis(benzoic acid) with four different arylidene diols and a common diol 1,2-bis(4-hydroxybenzoyloxy)ethane by direct polycondensation with diphenylchlorophosphate. The resulting polymers had inherent viscosities in the range 1.20–1.74 dl/g. Their structural features were investigated by Fourier transform infrared (FTIR), 1H, and 13C nuclear magnetic resonance (NMR) spectroscopy. The thermal behaviour of the copolyesters was investigated with differential scanning calorimetry and hot stage optical polarized microscopy. Our investigation on the effect of monomer structure on liquid crystalline behaviour shows that the copolymers containing bis(benzylidene)cycloalkanone exhibited higher melting and isotropization temperatures and extended liquid crystalline range. All of the copolymers showed some degree of crystallinity as evidenced by wide-angle X-ray diffraction and scanning electron microscopy. The photocrosslinkability of these polymers was established with UV irradiation/UV spectroscopy and scanning electron microscopy.

Copper and cadmium removal from synthetic industrial wastewater using chitosan and nylon 6

PURPOSE

Chitosan with nylon 6 membranes was evaluated as adsorbents to remove copper and cadmium ions from synthetic industrial wastewater.

METHODS

Chitosan and nylon 6 with glutaraldehyde blend ratio with (1:1+Glu, 1:2+Glu, and 2:1+Glu) have been prepared and these were used as membranes to remove copper and cadmium ions from synthetic industrial wastewater. Characterization of the synthesized membrane has been done with FTIR, XRD, TGA/DTA, DSC, and SEM. Chemical parameters for quantities of adsorption of heavy metal contamination have been done and the kinetics of adsorption has also been carried out.

RESULTS

The optimal pH for the removal of Cd(II) and Cu(II) using chitosan with nylon 6. Maximum removal of the metals was observed at pH 5 for both the metals. The effect of adsorbent dose also has a pronounced effect on the percentage of removal of the metals. Maximum removal of both the metals was observed at 5 g/100 ml of the adsorbent.

CONCLUSION

Copper and cadmium recovery is parallel at all time. The percentage of removal of copper increased with increase in the pH from 3 to 5. In the case of cadmium containing wastewater, the maximum removal of metal occurred at pH 5. The uptake amount of Cu(2+) ions on chitosan increased rapidly with increasing contact time from 0 to 360 min and then reaches equilibrium after 360 min; the equilibrium constant for copper and cadmium ions is more or less the same for the adsorption reaction.

Modification of pharmacokinetics of norfloxacin following oral administration of curcumin in rabbits

Investigation was carried out in adult New Zealand white rabbits to study the influence of curcumin pre-treatment on pharmacokinetic disposition of norfloxacin following single oral administration. Sixteen rabbits were divided into two groups of eight each consisting of either sex. Animals in group-I were administered norfloxacin (100 mg/kg body weight p.o), while animals in group-II received similar dose of norfloxacin after pre-treatment with curcumin (60 mg/kg body weight per day, 3 days, p.o). Blood samples were drawn from the marginal ear vein into heparin-coated vials at 0 (zero time), 5, 10, 15, 30 min and 1, 2, 4, 6, 12 and 24 h post-treatment. Plasma norfloxacin concentrations were determined by high performance liquid chromatography. The plasma concentration-time profile of norfloxacin was adequately described by a one-compartment open model. The pharmacokinetic data revealed that curcumin-treated animals had significantly (p < or = 0.05) higher area under the plasma concentration time curve and area under the first moment of plasma drug concentration-time curve. Prior treatment of curcumin significantly (p < or = 0.05) increased elimination half-life and volume of distribution of norfloxacin. Further treatment with curcumin reduced loading and maintenance doses by 26% and 24% respectively.

Evaluation of Testicular Toxicity Following Short-term Exposure to Cypermethrin in Albino Mice

The present study was undertaken to assess the testicular toxicity following short-term exposure to cypermethrin (α-CP) in albino mice. Cypermethrin was dissolved in arachis oil and administered to two groups of mice (n = 12/group) orally at the dose rate of 250 mg/kg body weight, once a day for 28 days. Fifty percent of the animals in both the groups were sacrificed on day 14 and the remaining on day 28. Plasma samples were subjected to radioimmunoassay to determine testosterone levels. The testes were collected to determine the cholesterol levels and the activity of transaminases (AST and ALT) or epididymal alkaline phosphatase (ALP). Histological study of testicular tissue was also undertaken to examine the α-CP-induced ultrastructural changes using transmission electron microscopy (TEM). α-CP significantly (P<0.05) increased the activities of testicular AST (1.36±0.12 vs. 1.19±0.10), ALT(1.78±0.11 vs. 1.36±0.09), and significantly (P<0.05) decreased the testosterone levels (0.86±0.24 vs. 1.72±0.18). Testicular cholesterol levels were elevated in treated animals as compared to control (1.81±0.16 vs. 1.42±0.08). Epididymal alkaline phosphatase (ALP) activity was also decreased significantly (P<0.05) in treated animals (1.10±0.20 vs. 1.64±0.1). Histological studies on day 28 revealed rupture of spermatogonic cell membrane, shrinkage in the nucleus, stages of apoptosis, condensation of chromatin, and decreased cytoplasmic organelles. The study suggested that short-term exposure to α-CP in albino mice induced toxicopathological lesions in testicular tissue leading to decreased plasma testosterone levels.

Genetic control of rodent midbrain dopaminergic neuron development in the light of human disease

Dopamine-producing neurons in the mammalian midbrain have received considerable attention in recent years because of their involvement in diverse neurological and psychiatric human disorders such as Parkinson's Disease (PD), schizophrenia and addiction. Although the underlying pathogenic mechanisms of these disorders are far from being understood, it is meanwhile accepted that a combination of genetic predisposition and environmental factors lead to the disease state. More recent evidence also suggests that both neurological and psychiatric disorders result from early disturbances affecting the normal development of the mesencephalic dopaminergic (mesDA) neurons. Understanding the cues directing the generation of the different mesDA cell groups, the establishment of their proper connections within the brain and their maintenance in the adult are therefore also of great clinical interest. Rodents, and in particular the mouse, have served as the classical "surrogate" organism for these studies based on their phylogenetic relationship to humans, their relatively well characterized mesDA system on both the anatomical and physiological levels, and especially on the propensity of the mouse to genetic manipulation enabling the dissection of genetic pathways underlying the proper generation and maintenance of the mesDA system in this species. In the present review, we will summarize recent findings in the overall context of murine mesDA neuron development.
