Protective effect of intravitreal injection of vasoactive intestinal peptide-loaded liposomes on experimental autoimmune uveoretinitis.

PURPOSE: The aim of this study was to investigate the effect of a single intravitreal (i.v.t.) injection of vasoactive intestinal peptide (VIP) loaded in rhodamine-conjugated liposomes (VIP-Rh-Lip) on experimental autoimmune uveoretinitis (EAU). METHODS: An i.v.t. injection of VIP-Rh-Lip, saline, VIP, or empty-(E)-Rh-Lip was performed simultaneously, either 6 or 12 days after footpad immunization with retinal S-antigen in Lewis rats. Clinical and histologic scores were determined. Immunohistochemistry and cytokine quantification by multiplex enzyme-linked immunosorbent assay were performed in ocular tissues. Systemic immune response was determined at day 20 postimmunization by measuring proliferation and cytokine secretion of cells from inguinal lymph nodes (ILNs) draining the immunization site, specific delayed-type hypersensitivity (DTH), and the serum concentration of cytokines. Ocular and systemic biodistribution of VIP-Rh-Lip was studied in normal and EAU rats by immunofluorescence. RESULTS: The i.v.t. injection of VIP-Rh-Lip performed during the afferent, but not the efferent, phase of the disease reduced clinical EAU and protected against retinal damage. No effect was observed after saline, E-Rh-Lip, or VIP injection. VIP-Rh-Lip and VIP were detected in intraocular macrophages and in lymphoid organs. In VIP-Rh-Lip-treated eyes, macrophages expressed transforming growth factor-beta2, low levels of major histocompatibility complex class II, and nitric oxide synthase-2. T-cells showed activated caspase-3 with the preservation of photoreceptors. Intraocular levels of interleukin (IL)-2, interferon-gamma (IFN-gamma), IL-17, IL-4, GRO/KC, and CCL5 were reduced with increased IL-13. At the systemic level, treatment reduced retinal soluble autoantigen lymphocyte proliferation, decreased IL-2, and increased IL-10 in ILN cells, and diminished specific DTH and serum concentration of IL-12 and IFN-gamma. CONCLUSIONS: An i.v.t. injection of VIP-Rh-Lip, performed during the afferent stage of immune response, reduced EAU pathology through the immunomodulation of intraocular macrophages and deviant stimulation of T-cells in ILN. Thus, the encapsulation of VIP within liposomes appears as an effective strategy to deliver VIP into the eye and is an efficient means of the prevention of EAU severity.

Involuntary Discharge from a Long-Term Facility

An involuntary discharge from a long-term care (LTC) facility occurs when the facility provides a 30-day written notice to a resident informing him/her of the need to move out of the facility. The notice must set out the reasons for the transfer or discharge as well as state the effective date, location of transfer or discharge, statement of appeal rights and the contact information (name, address and telephone number) for the Office of the State Long-Term Care Ombudsman.

Letter health consultation : Doty Landfill site, Camanche, Iowa EPA Facility ID: IAD980497556 (2008)

The Doty Landfill encompasses 13 acres of land and is located in the southeastern quarter of Section 29, Township 81 North, Range 6 East, Clinton County, Iowa. The site was used as a landfill for municipal solid waste from 1970 to 1975. In addition, local residents have expressed concern that other chemical-or pesticide waste had been disposed at the site. Previous site investigations had been completed in 1992 and in 2005. In October 2007 water samples from private wells located in the vicinity of the Doty Landfill site were collected and analyzed for dissolved metals. Two of the water samples obtained from drinking water wells contained dissolved arsenic above the US EPA Maximum Contaminant Level (MCL) for arsenic of 10 μg/L (micrograms per liter) or 10 ppb (parts per billion). The water samples in question contained dissolved arsenic at concentrations of 19.3 and 14.9 μg/L or 19.3 and 14.9 ppb.

Public health assessment : Railroad Avenue groundwater contamination, West Des Moines, Polk County, Iowa EPA facility ID: IA0001610963 (2004)

The Railroad Avenue groundwater contamination site (the site) is in West Des Moines, Polk County, Iowa. Located on approximately 120 acres. The site comprises mixed residential, industrial and commercial properties. Underneath the site, chlorinated volatile organic compounds (VOCs) have contaminatcd the shallow (i.e., 30-50 feet deep) groundwater. These compounds have compromised several shallow wells within the West Des Moines water works system. A contamination source, however, has not yet been identified. In 1993, routine water analysis by the City of West Des Moines identified 1, 2 cis-dichlorocthylcne (1, 2 cis-DCE) at a concentration of 1.2 μg/L (micrograms) per liter of water) in the water supply. Subsequently. several shallow municipal wells were found to be contaminated by VOCs, including 1. 2 cis-DCE, trichloroethylene (TCE), tetrachloroethylene (PCE) and benzene. Five of these wells have been taken out of service. Because of the impact on the West Des Moines water supply, the U.S. Environmental Protection Agency (USEPA) has assigned the site to the National Priorities List. Surface water und sediment at the site have not been impacted by the VOCs. Testing for VOCs in surface soils has not revealed any significant VOC contamination. Subsurface soils -- generally 8 feet or greater in depth -- are contaminated with VOCs, but at levels which should not present a health hazard. The past, present, and future health hazard category chosen for this site is no apparent public health hazard. This category is used when exposure to toxins might be occurring or might have occurrcd in the past, but at levels below any known health hazard. Analysis of available environmental data has not revealed that residental or commercial water customers are or have been exposed to VOCs at concentrations that might cause any adverse health effects.

Health consultation : Hills, Iowa perchlorate groundwater contamination site, Hills, Johnson County, EPA facility ID: IAN 000704368 (2004)

The U. S. Environmental Protection Agency (EPA) Region 7, as well as concerned citizens, asked the Iowa Department of Public Health (IDPH) Hazardous Waste Site Health Assessment Program to perform a health consultation for the Hills, Iowa Perchlorate Groundwater Contamination Site. Specifically, IDPH was asked to determine if EPA’s action of providing bottled water to residents whose private wells had concentrations of greater than 18 μg/L (micrograms per liter) or 18 parts per billion (ppb) perchlorate is protective of public health, and to address some community health concerns. The information included in this health consultation was current at the time of writing. Data that emerges later could alter this document’s conclusions and recommendations.

Effect of repetitive arm cycling following botulinum toxin injection for poststroke spasticity: evidence from FMRI.

BACKGROUND AND OBJECTIVE: Investigations were performed to establish if repetitive arm cycling training enhances the antispastic effect of intramuscular botulinum toxin (BTX) injections in postischemic spastic hemiparesis. Effects on cerebral activation were evaluated by functional magnetic resonance imaging (fMRI). METHODS: Eight chronic spastic hemisyndrome patients (49 ± 10 years) after middle cerebral artery infarction (5.5 ± 2.7 years) were investigated. BTX was injected into the affected arm twice, 6 months apart. Spasticity was assessed using the Ashworth Scale and range of motion before and 3 months after BTX injections. Images were analyzed using Brain Voyager QX 1.8, and fMRI signal changes were corrected for multiple comparisons. RESULTS: During passive movements of affected and nonaffected hands, fMRI activity was increased bilaterally in the sensorimotor cortex (MISI), secondary somatosensory areas (SII), and supplementary motor area predominantly in the contralesional hemisphere, compared with the rest. Following repetitive arm cycling, fMRI activity increased further in MISI of the lesioned hemisphere and SII of the contralesional hemisphere. For patients with residual motor activity, treatment-related fMRI activity increases were associated with reduced spasticity; in completely plegic patients, there was no fMRI activity change in SII but increased spasticity after training. CONCLUSION: Increased activity in SII of the contralesional hemisphere and in MISI of the lesioned hemisphere reflect a treatment-induced effect in the paretic arm. It is hypothesized that the increased BOLD activity results from increased afferent information related to the antispastic BTX effect reinforced by training.

Serum hyperglycosylated human chorionic gonadotropin to predict the gestational outcome in in vitro fertilization/intracytoplasmic sperm injection pregnancies.

Hyperglycosylated human chorionic gonadotropin (H-hCG) is secreted by the placenta in early pregnancy. Decreased H-hCG levels have been associated with abortion in spontaneous pregnancy. We retrospectively measured H-hCG and dimeric hCG in the sera of 87 in vitro fertilization patients obtained in the 3 weeks following embryo transfer and set the results in relation to pregnancy outcome. H-hCG and dimeric hCG were correlated (r(2) = 0.89), and were significantly decreased in biochemical pregnancy (2 microg/l and 18 IU/l, respectively) compared to early pregnancy loss (22 microg/l and 331 IU/l) and ongoing pregnancy (32 microg/l and 353 IU/l). Only H-hCG tended to discriminate between these last two groups.
