The Iowa Department of Public Health Bureau of Family Health and the Child Health Specialty Clinics embarked on a five-year needs assessment in March 2008 with a daylong strategic planning session involving key administrative and staff personnel from both agencies. As part of the strategic planning, the participants began preparation of a comprehensive assessment to identify the need in Iowa for: preventive and primary care services for pregnant women, mothers, and infants; preventive and primary care services for children; and services for children and youth with special health care needs.

In recent years, several vasopressin antagonists have been developed that block V-1 receptors either selectively or nonselectively.(1,2) To date, one combined V-1/V-2 antagonist (primarily a V-2 antagonist, as determined on the basis of human receptor binding data), conivaptan, has been approved for the treatment of euvolemic hyponatremia.(3,4) We have previously shown that the vascular properties of a vasopressin V-1 antagonist can be investigated safely and reliably in healthy subjects. We used the measurement of skin blood flow after intradermic injection of exogenous arginine vasopressin on a skin area prevasodilated with calcitonin gene-related peptide (CGRP).(3,5) This technique enables the documentation of the dose-dependent effects of vasopressin or vasopressin antagonists. In this study, we have characterized the V-1a pharmacodynamic profile of increasing doses of RWJ-676070, a new orally active dual V-1a/V-2 receptor antagonist, in healthy subjects.(5)

Medulloblastoma, the most common malignant paediatric brain tumour, is currently treated with nonspecific cytotoxic therapies including surgery, whole-brain radiation, and aggressive chemotherapy. As medulloblastoma exhibits marked intertumoural heterogeneity, with at least four distinct molecular variants, previous attempts to identify targets for therapy have been underpowered because of small samples sizes. Here we report somatic copy number aberrations (SCNAs) in 1,087 unique medulloblastomas. SCNAs are common in medulloblastoma, and are predominantly subgroup-enriched. The most common region of focal copy number gain is a tandem duplication of SNCAIP, a gene associated with Parkinson's disease, which is exquisitely restricted to Group 4α. Recurrent translocations of PVT1, including PVT1-MYC and PVT1-NDRG1, that arise through chromothripsis are restricted to Group 3. Numerous targetable SCNAs, including recurrent events targeting TGF-β signalling in Group 3, and NF-κB signalling in Group 4, suggest future avenues for rational, targeted therapy.

En las páginas siguientes se estudian las diatomeas contenidas en una serie de recolecciones que no han sido utilizadas en la preparación de trabajos de tipo regional publicados anteriormente, aunque una parte de estos materiales inéditos se aprovechó para un estudio sobre la vegetación de las aguas dulces de Cataluña (Vegetatio, vol. i, págs. 258-284, 1949), en el que se pueden encontrar algunas referencias complementarias sobre ecologÃa y biocenologÃa de las especies.

Los numerosos trabajos sobre fitobentos marino de las islas Baleares fueron recopilados en los catálogos florÃsticos de RIBERA & GÓMEZ (Collect. Bot. (Barcelona) 15: 377-406. 1984; Collect. Bot. (Barcelona) 16:25-41.1985). Posteriormente, debido a la realización de numerosos estudios bentónicos de la zona, se han publicado adiciones a dicho catálogo (PERICAS, Boll. Soc. Hist. Nat. Balears: 139-146.1984; BALLESTEROS, Bull. Inst. Cat. Hist. Nat. 51 (See. Bot, 5): 31-33. 1984; BALLESTEROS, Fol. Bot. Mise. 6: 65-70. 1989; RULL LLUCH, GÓMEZ GARRETA and RIBERA Collect. Bot.

OBJECTIVE: Proinsulin is a precursor of mature insulin and C-peptide. Higher circulating proinsulin levels are associated with impaired β-cell function, raised glucose levels, insulin resistance, and type 2 diabetes (T2D). Studies of the insulin processing pathway could provide new insights about T2D pathophysiology. RESEARCH DESIGN AND METHODS: We have conducted a meta-analysis of genome-wide association tests of ∼2.5 million genotyped or imputed single nucleotide polymorphisms (SNPs) and fasting proinsulin levels in 10,701 nondiabetic adults of European ancestry, with follow-up of 23 loci in up to 16,378 individuals, using additive genetic models adjusted for age, sex, fasting insulin, and study-specific covariates. RESULTS: Nine SNPs at eight loci were associated with proinsulin levels (P < 5 × 10(-8)). Two loci (LARP6 and SGSM2) have not been previously related to metabolic traits, one (MADD) has been associated with fasting glucose, one (PCSK1) has been implicated in obesity, and four (TCF7L2, SLC30A8, VPS13C/C2CD4A/B, and ARAP1, formerly CENTD2) increase T2D risk. The proinsulin-raising allele of ARAP1 was associated with a lower fasting glucose (P = 1.7 × 10(-4)), improved β-cell function (P = 1.1 × 10(-5)), and lower risk of T2D (odds ratio 0.88; P = 7.8 × 10(-6)). Notably, PCSK1 encodes the protein prohormone convertase 1/3, the first enzyme in the insulin processing pathway. A genotype score composed of the nine proinsulin-raising alleles was not associated with coronary disease in two large case-control datasets. CONCLUSIONS: We have identified nine genetic variants associated with fasting proinsulin. Our findings illuminate the biology underlying glucose homeostasis and T2D development in humans and argue against a direct role of proinsulin in coronary artery disease pathogenesis.
