Data mining multiple stakeholders’ responses to declining schizothorax fishery in the lakes of Kashmir, India
This study documented the historical perspective of lake fisheries in Kashmir, India, estimated the trends in fish production using the Kane’s cross impact analysis and the stakeholders’ willingness to pay (WTP) for the restoration of Schizothorax fishery in the lakes of Kashmir. The cross impacts of introduction of carps in the lakes of Kashmir on Schizothorax fishery and total fish production are evaluated by Kane’s cross impact analysis. Considering the obvious shortcomings of logistic regression, Classification and Regression Trees (CART) has been used for data mining multiple stakeholders’ responses to make a case for sustainable development of the Schizothorax fishery in the lakes of Kashmir. On the whole, time spent on the lakes to earn their livelihoods emerged as the root node, as the single most important variable that determined WTP of stakeholders followed by income, type of stakeholder and age in the tree model. The CART analysis not only yielded the variables that determined the WTP but the pruned tree gave the hierarchy of the variables that determined WTP. The results of the study strongly made a case for a concerted multi-institutional action plan for the restoration of Schizothorax fishery in the lakes of Kashmir.Keywords: Modeling and Economic Theory, Environment: Valuation, Fisheries Economic
Inotuzumab ozogamicin in pediatric patients with relapsed/refractory acute lymphoblastic leukemia
Although inotuzumab ozogamicin (InO) is recognized as an effective agent in relapsed acute lymphoblastic leukemia (ALL)
in adults, data on safety and efficacy in pediatric patients are scarce. We report the use of InO in 51 children with relapsed/
refractory ALL treated in the compassionate use program. In this heavily pretreated cohort, complete remission was achieved
in 67% of patients with overt marrow disease. The majority (71%) of responders were negative for minimal residual disease.
Responses were observed irrespective of cytogenetic subtype or number or type of prior treatment regimens. InO was welltolerated; grade 3 hepatic transaminitis or hyperbilirubinemia were noted in 6 (12%) and grade 3/4 infections in 11 (22%)
patients. No patient developed sinusoidal obstruction syndrome (SOS) during InO therapy; however, 11 of 21 (52%) patients
who underwent hematopoietic stem cell transplantation (HSCT) following InO developed SOS. Downregulation of surface
CD22 was detected as a possible escape mechanism in three patients who developed a subsequent relapse after InO. We
conclude that InO is a well-tolerated, effective therapy for children with relapsed ALL and prospective studies are warranted.
Identification of risk factors for developing post-HSCT SOS and strategies to mitigate this risk are ongoing
Genetics of the thrombomodulin-endothelial cell protein C receptor system and the risk of early-onset ischemic stroke.
Background and Purpose:
Polymorphisms in coagulation genes have been associated with early-onset ischemic stroke. Here we pursue an a priori hypothesis that genetic variation in the endothelial-based receptors of the thrombomodulin-protein C system (THBD and PROCR) may similarly be associated with early-onset ischemic stroke. We explored this hypothesis utilizing a multi-stage design of discovery and replication.
Methods:
Discovery was performed in the Genetics-of-Early-Onset Stroke (GEOS) Study, a biracial population-based case-control study of ischemic stroke among men and women aged 15-49 including 829 cases of first ischemic stroke (42.2% African-American) and 850 age-comparable stroke-free controls (38.1% African-American). Twenty-four single-nucleotide-polymorphisms (SNPs) in THBD and 22 SNPs in PROCR were evaluated. Following LD pruning (r2≥0.8), we advanced uncorrelated SNPs forward for association analyses. Associated SNPs were evaluated for replication in an early-onset ischemic stroke population (onset-age<60 years) consisting of 3676 cases and 21118 non-stroke controls from 6 case-control studies. Lastly, we determined if the replicated SNPs also associated with older-onset ischemic stroke in the METASTROKE data-base.
Results:
Among GEOS Caucasians, PROCR rs9574, which was in strong LD with 8 other SNPs, and one additional independent SNP rs2069951, were significantly associated with ischemic stroke (rs9574, OR = 1.33, p = 0.003; rs2069951, OR = 1.80, p = 0.006) using an additive-model adjusting for age, gender and population-structure. Adjusting for risk factors did not change the associations; however, associations were strengthened among those without risk factors. PROCR rs9574 also associated with early-onset ischemic stroke in the replication sample (OR = 1.08, p = 0.015), but not older-onset stroke. There were no PROCR associations in African-Americans, nor were there any THBD associations in either ethnicity.
Conclusion:
PROCR polymorphisms are associated with early-onset ischemic stroke in Caucasians
Hydrogeological typologies of the Indo-Gangetic basin alluvial aquifer, South Asia
The Indo-Gangetic aquifer is one of the world’s most important transboundary water resources, and the most heavily exploited aquifer in the world. To better understand the aquifer system, typologies have been characterized for the aquifer, which integrate existing datasets across the Indo-Gangetic catchment basin at a transboundary scale for the first time, and provide an alternative conceptualization of this aquifer system. Traditionally considered and mapped as a single homogenous aquifer of comparable aquifer properties and groundwater resource at a transboundary scale, the typologies illuminate significant spatial differences in recharge, permeability, storage, and groundwater chemistry across the aquifer system at this transboundary scale. These changes are shown to be systematic, concurrent with large-scale changes in sedimentology of the Pleistocene and Holocene alluvial aquifer, climate, and recent irrigation practices. Seven typologies of the aquifer are presented, each having a distinct set of challenges and opportunities for groundwater development and a different resilience to abstraction and climate change. The seven typologies are: (1) the piedmont margin, (2) the Upper Indus and Upper-Mid Ganges, (3) the Lower Ganges and Mid Brahmaputra, (4) the fluvially influenced deltaic area of the Bengal Basin, (5) the Middle Indus and Upper Ganges, (6) the Lower Indus, and (7) the marine-influenced deltaic areas
Metal impaction: an unusual cause of dysphagia
A 41-year-old unemployed construction worker with a background of insulin-dependent diabetes mellitus, hypertension, chronic kidney disease stage 3, previous incisor tooth abscess aged 9, for which he was fitted with metal dentures, underwent a right below knee amputation. Postoperative day 8 he experienced episodes of dysphagia and vomiting postparandial. CT thorax revealed a foreign body in the midline region of the mediastinum. After two failed attempts at endoscopic extraction of the metal denture, the patient underwent surgical extraction of his metal denture
