Sanjay Agarwala,Mayank Vijayvargiya 대한재활의학회 2019 Annals of Rehabilitation Medicine Vol.43 No.3

Objective To shorten the natural course of transient osteoporosis of hip (TOH), which is a self-limiting idiopathic condition and requires 6–12 months for the resolution of symptoms, various therapies including treatment with bisphosphonates have been attempted. There exist fewer case reports evaluating the effect of bisphosphonates in TOH and most of them lack radiographic evidence of resolution of disease. The present study was carried out with an aim to evaluate the clinical and radiological outcomes of TOH patients subsequent to treatment with a single dose of zoledronic acid. Methods Data of 19 adult male and non-pregnant female patients with TOH treated with zoledronic acid were included in the study. Efficacy was assessed using changes in clinical signs and symptoms, visual analogue scale pain score, and changes in bone marrow edema (BME) in magnetic resonance imaging (MRI). Results Mean age of the patients was 42.1 years, 17 being males. The mean time of onset of symptom was 4 weeks. Subsequent to treatment, the patients were pain-free and had no limp within an average of 2.8 weeks (range, 2–5 weeks) and remained asymptomatic at a mean follow-up of 35 months (range, 6–54 months). The post-treatment MRI showed resolution of BME in approximately 84% (16/19) of patients at 3 months. No major adverse events were reported. None of the patients progressed to avascular necrosis at their last follow-up. Conclusion Intravenous single dose administration of zoledronic acid provides early pain relief and complete reversal of TOH. Consequently, zoledronic acid is proposed as a new paradigm in the management of TOH.

Harmonia dimidiata (Fabricius) (Coleoptera: Coccinellidae) is the dominant predator of the aphid species Cervaphis quercus Takahashi. This aphid is a serious pest of oak trees in several parts of north-east India. Young leaves of oak trees are used in sericulture by rural people and by industry in several parts of north-east India. The effect of different aphid densities on food consumption and fecundity of H. dimidiata was studied in the laboratory. Female beetles were maintained from the time of eclosion till death at a fixed density of 25, 50, 75,100 or 125 aphids. Both the functional response and the reproductive numerical response showed the upper asymptote at 100 adult aphids/female. At this density, females matured earlier and produced more eggs over a longer reproductive period. At lower prey densities, females matured late and they either did not produce eggs or produced fewer eggs. At the higher prey densities, females did not produce more eggs than the asymptote. Results suggested that H. dimidiata are an effective predator of C. quercus aphids on oak trees and could be exploited as a biological control agent in the rising phase of aphid population growth.

Genetic and morphological differentiation of insect populations in relation to the use of different host plants is an important phenomenon that leads to ecological specialization. In this study, we describe variations in morphology, and in ecological and biological parameters of Lipaphis pseudobrassicae (Kaltenbach) clones associated with three host species of Cruciferae, Brassica juncea (L.) var. rai sarson Czern and Cross (brown mustard), Brassica campestris L. var. sarson Prain (yellow mustard), and Rorippa indica (L.) Hiern (wild herb). This study was aimed at obtaining evidence regarding phenotypic differentiation induced by, or associated with, the use of distinct host species. Ten morphological characters, 4 growth parameters and 8 biological functions were investigated in wingless aphids collected from plants of the three host species. Aphids from B. campestris and B. juncea clones were bigger in size, heavier in weight and showed higher growth rates and fecundity than the clones from R. indica. Between the two crop plants, clones from B. juncea showed significantly higher growth rates than the clones from B. campestris. Transfer of L. pseudobrassicae populations from B. campestris to B. juncea and R. indica and vice versa resulted in poor performance. Results indicate that the average phenotype of L. pseudobrassicae individuals inhabiting different host plant species differs as a consequence of the contrasting feeding environments the host species provide.

The dilemma of differentiating between acute hepatitis B and chronic hepatitis B with acute exacerbation: Is quantitative serology the answer?

Sujata Lall,Pragya Agarwala,Guresh Kumar,Manoj Kumar Sharma,Ekta Gupta 대한간학회 2020 Clinical and Molecular Hepatology(대한간학회지) Vol.26 No.2

Background/Aims: Acute exacerbations of chronic hepatitis B (CHB-AEs) are common in endemic areas and are often presumed to be acute hepatitis B (AHB) due to their similarities in clinical and serological pictures, presenting a major diagnostic dilemma. This study aimed to identify laboratory markers for differentiating between the two groups, and to establish the cut-off value for significant markers. Methods: A retrospective analysis of records was conducted for patients who presented with clinical features of acute hepatitis along with hepatitis B surface antigen (HBsAg) and IgM antibody to hepatitis B core antigen (IgM anti-HBc) positivity from May 2015 to May 2017. A total of 172 patients were enrolled and grouped as AHB (n=89) and CHB-AE (n=83) based on their history of hepatitis B virus infection and duration of HBsAg persistence. Virological and biochemical parameters were analyzed and compared. Cut-off values, sensitivity, and specificity of the variables were calculated. Results: The median value of signal by cut-off (S/Co) ratio for IgM anti-HBc was significantly higher in AHB group (30.44) compared to CHB-AE group (8.63) with a sensitivity and specificity of 97% and 84%, respectively, at a cut-off of 20.5 (P<0.01). The mean international normalized ratio (INR) was significantly greater in CHB-AE (1.88±1.24) group compared to AHB group (1.62±0.17) with a sensitivity and specificity of 57.9% and 45.1%, respectively, at a cut-off value of 1.27. Conclusions: A value of 20.5 S/Co of IgM anti-HBc and 1.27 INR could be helpful in differentiating between AHB and CHB-AE.

The genetic architecture of type 2 diabetes

Fuchsberger, Christian,Flannick, Jason,Teslovich, Tanya M,Mahajan, Anubha,Agarwala, Vineeta,Gaulton, Kyle J,Ma, Clement,Fontanillas, Pierre,Moutsianas, Loukas,McCarthy, Davis J,Rivas, Manuel A,Perry, Macmillan Journals ltd., etc.] 2016 Nature Vol.536 No.7614

<P>The genetic architecture of common traits, including the number, frequency, and effect sizes of inherited variants that contribute to individual risk, has been long debated. Genome-wide association studies have identified scores of common variants associated with type 2 diabetes, but in aggregate, these explain only a fraction of heritability. To test the hypothesis that lower-frequency variants explain much of the remainder, the GoT2D and T2D-GENES consortia performed whole genome sequencing in 2,657 Europeans with and without diabetes, and exome sequencing in a total of 12,940 subjects from five ancestral groups. To increase statistical power, we expanded sample size via genotyping and imputation in a further 111,548 subjects. Variants associated with type 2 diabetes after sequencing were overwhelmingly common and most fell within regions previously identified by genome-wide association studies. Comprehensive enumeration of sequence variation is necessary to identify functional alleles that provide important clues to disease pathophysiology, but large-scale sequencing does not support a major role for lower-frequency variants in predisposition to type 2 diabetes.</P>

Praveen Kumar,Chandrasekhar Bal,Nishikant Avinash Damle,Sanjana Ballal,S. N. Dwivedi,Sandeep Agarwala 대한핵의학회 2019 핵의학 분자영상 Vol.53 No.3

Purpose The effective half-life of radioiodine is an important parameter for dosimetry in differentiated thyroid cancer patients, particularly in children. We determined the pre-therapy and post-therapy effective half-life in different types of lesions, i.e., remnant, node, or lung metastases. Methods Of 84 patients recruited, 27 were < 18 years (group 1) and the remaining 57 were between 18 and 21 years (group 2). A total of 114 studies were conducted and 253 lesions were analyzed. Serial whole-body scans were acquired at 24, 48, and ≥ 72 h after administration of iodine-131. Region of interests was drawn over lesions to determine counts in the lesion. Time versus counts graphs were plotted and mono-exponentially fitted to determine effective half-life. Results The post-therapy effective half-life was found to be lesser than pre-therapy effective half-life in all types of lesions and in all groups. Median effective half-life was found maximum in intact lobe, minimum in the lung, and intermediate in remnant and nodes. In the assessment of all lesions together, pre- and post-therapy median and interquartile range (IQR) effective half-life were 59.8 (37–112) h and 48.6 (35.2–70.8) h (p < 0.0001) in group 1, 73.9 (46.2–112.7) h and 60 (57.4–85.9) h (p < 0.0001) in group 2, and 68.6 (41.53–112.36) h and 54.7 (36–80.6) h (p < 0.0001) in combined group, respectively. Importantly, the pre- and post-therapy median effective half-life serially dropped after each successive cycles of iodine-131. Conclusions There was a significant difference in pre-therapy and post-therapy effective half-life in all types of lesions. These results may have implications in calculating the correct therapeutic dose in children and in young adults.

Cardio-oncology is an emerging multi-disciplinary field, which aims to reduce morbidity and mortality of cancer patients by preventing and managing cancer treatment-related cardiovascular toxicities. With the exponential growth in cancer and cardiovascular diseases in Asia, there is an emerging need for cardio-oncology awareness among physicians and country-specific cardio-oncology initiatives. In this state-of-the-art review, we sought to describe the burden of cancer and cardiovascular disease in Asia, a region with rich cultural and socio-economic diversity. From describing the uniqueness and challenges (such as socio-economic disparity, ethnical and racial diversity, and limited training opportunities) in establishing cardio-oncology in Asia, and outlining ways to overcome any barriers, this article aims to help advance the field of cardio-oncology in Asia.
