Abstract	The deep-sea spiny eels of the genus Notacanthus Bloch 1788 are currently represented by six valid species, of which only one, Notacanthus indicus, has been described so far from the Arabian Sea, part of the Western Indian Ocean. This paper reports the discovery of a new species, described herein as Notacanthus laccadiviensis, from the outer reef drop-off, off the Kavaratti Island, Lakshadweep Archipelago, Arabian Sea. The new species differs from its congeners in the shape of the head; morphology of dorsal, pectoral and anal fins; number of gill rakers; number of vertebrae; and body colour, and specifically from N. indicus (the only known congener from the Indian Ocean) in the unusual morphology of the dorsal fin, and number of rays in the dorsal and pectoral fins.

Article ; Online: Caring for Undocumented Immigrants With Kidney Disease.

Raghavan, Rajeev

2017 Volume 71, Issue 4, Page(s) 488–494

Abstract	The care of dialysis-dependent undocumented immigrants exemplifies a problem at the crux of 2 US national agendas: immigration and health care reform. Undocumented immigrants represent 3% of the US population and 27% of the uninsured, and an estimated 6,500 individuals are dialysis dependent. With no uniform national policy, an estimated 30% to 50% of these individuals receive treatment only in life-threatening situations (emergent dialysis). Since 2005, about 400 undocumented immigrants have received a kidney transplant (>70% living). Although the Affordable Care Act specifically excluded noncitizens, its policies have indirectly allowed more than 200 individuals to purchase insurance from a health insurance exchange and transition from emergent to thrice-weekly hemodialysis. Under the Trump administration, uncertainties with health care plans, threats of deportation, and rescinding of policies such as sanctuary city status are bound to result in unforeseen challenges for this vulnerable population. Global variation in the care accessible to migrants, refugees, undocumented immigrants, and asylum seekers argues for the need for a framework to transform advocacy into public policy to improve the lives of patients with kidney disease worldwide. Access to nonemergent dialysis is humane and cost-effective; it deserves to be espoused and advocated by leading medical organizations.

Abstract	This study investigates the fish assemblage in a temporarily-closed sandbar estuary along India's west coast, across different zones and seasons. Moderate species diversity (54 species), low species abundance, varying fish diversity from lower to upper estuarine gradient (higher counts in lower zones, and decreasing from middle to upper zones), and higher prevalence of marine migrants (estuarine use) and piscivorous species (feeding mode) were the significant characteristics of the estuary. Distinct spatial, seasonal, and estuarine mouth state-based variations were recorded in the estuary, based on diversity indices and count of taxa. Peak diversity and abundance were noted during the pre-monsoon, and during the open mouth state of the estuary. The entire estuarine gradient is anthropogenically impacted by a multitude of stressors, except at the estuarine mouth region, which is favored by marine connectivity. The fish assemblage structure in Poonthura estuary (PE) has thus far remained unaffected by anthropogenic disturbances. Nevertheless, growth and nursery function of the estuary have been significantly compromised. The predominance of juvenile fish in the ecosystem, and prevailing anthropogenic stressors from point and non-point sources underscore the necessity for long-term maintenance of the population of coastal species, as well as a need for developing and implementing urgent management strategies for this fragile ecosystem.

Abstract	The mitogenome of Lepidopygopsis typus, an evolutionarily distinct, endangered, cyprinid fish from the Western Ghats Biodiversity Hotspot, was characterized. Total length of the mitogenome was 16,729 bp, and comprised of 13 protein coding, 22 tRNA and two rRNA genes. Thirteen protein coding genes contributed a total nucleotide length of 11,408 bp, which coded for a total of 3794 amino acids and accounting for 68.2 % of the mitogenome. A maximum likelihood phylogenetic tree based on mitogenomes of members of cyprinid subfamilies Torinae, Schizothoracinae and Schizopygopsinae, recovered L. typus in a well-resolved clade of Torinae with members of the Western Ghats endemic genus Hypselobarbus as sister taxa. Selection analysis suggested that the branch of L. typus and Hypselobarbus spp. was under intensified selection with reference to other members of Torinae. There were 19 codons under diversifying selection in L. typus, which could be the result of positive selection for adapting to high-altitude, upstream tributaries of Periyar River, where the species has a restricted distribution. With respect to Hypselobarbus spp., L. typus was under relaxed selection with about 68 % of codons experiencing neutral evolution. Restricted distribution, low population size and relaxation in selection can likely trigger extinction in L. typus, and therefore urgent conservation and monitoring plans are required to secure the future of this evolutionary distinct, and globally endangered species.

Abstract	Fusiliers of the family Caesionidae comprise a group of Indo-Pacific reef fishes important in the live bait and artisanal fisheries in many parts of its range, particularly in the Indian Ocean region. Using newly generated mitochondrial COI sequences of 10 species of caesionid fishes from the Laccadive archipelago, we carried out a molecular phylogenetic analysis, which has helped improve our understanding of the diversity, distribution, and systematics of this poorly known group of fishes. The two speciose genera within Caesionidae, Caesio and Pterocaesio, were revealed to be paraphyletic, and as a result, four names earlier considered as subgenera within Caesionidae (Flavicaesio, Odontonectes, Pisinnicaesio, and Squamosicaesio) were elevated to the status of distinct genera. We also discovered the presence of a new lineage in the Central Indian Ocean, sister to Caesio caerulaurea and Caesio xanthalytos, but distinct from both in several morphological characters and a genetic distance of between 2% and 3% in the mitochondrial COI gene. We describe this lineage as Caesio idreesi, a new species, with a distribution spanning the Laccadive Sea and the Bay of Bengal. Our genetic data also helped confirm the first confirmed records of two species, Pisinnicaesio digramma and Squamosicaesio randalli, from the Central Indian Ocean, and a new distribution record for C. xanthalytos in the Laccadive Sea. Combined, these results have helped bridge key biodiversity knowledge gaps of the family Caesionidae and form an excellent baseline for further investigations on their taxonomy, systematics, and life history.

Article ; Online: New Opportunities for Funding Dialysis-Dependent Undocumented Individuals.

Abstract	The cost of dialysis for the estimated 6500 dialysis-dependent undocumented individuals with kidney failure in the United States is high, the quality of dialysis care they receive is poor, and their treatment varies regionally. Some regions use state and matched federal funds to cover regularly scheduled dialysis treatments, while others provide treatment only in emergent life-threatening conditions. Nephrologists caring for patients who receive emergent dialysis are tasked with the difficult moral dilemma of determining "who gets dialysis that day." Without a path to citizenship and by exclusion from the federal marketplace exchanges, undocumented individuals have limited options for their treatment. A novel opportunity to provide scheduled dialysis for this population is through the purchase of insurance off the exchange. Plans purchased off the exchange must still abide by the 2014 provision of the Patient Protection and Affordable Care Act, which prohibits insurance companies from denying coverage based on a preexisting health condition. In 2015 and 2016, >100 patients previously receiving only emergent dialysis at the two largest safety-net hospital systems in Texas obtained off-the-exchange commercial health insurance plans. These undocumented patients now receive scheduled dialysis treatments, which has improved their care and quality of life, as well as decompressed the overburdened hospital systems. The long-term sustainability of this option is not known. Socially responsive and visionary policymakers allowing the move into this bold, new direction deserve special appreciation.
