Abstract
BACKGROUND Elder mistreatment (EM) harms individuals, families, communities, and society as a whole. Yet research on interventions is lagging, and no rigorous studies demonstrating effective prevention have been published. This pilot study examines whether a first-of-its-kind coaching intervention reduced the experience of EM among older adults with chronic health conditions, including dementia. METHODS We used a double-blind, randomized controlled trial to test a strengths-based person-centered caregiver support intervention, developed from evidence-based approaches used in other types of family violence. Participants (n = 80), family caregivers of older adults who were members of Kaiser Permanente, completed surveys at baseline, post-test, and 3-month follow-up. The primary outcome was caregiver-reported EM; additional proximal outcomes were caregiver burden, quality-of-life, anxiety, and depression. Nonparametric tests (Mann-Whitney U, Fisher's Exact, Wilcoxon Signed Rank, and McNemar's) were used to make comparisons between treatment and control groups and across time points. RESULTS The treatment group had no EM after intervention completion (assessed at 3-month follow-up), a significantly lower rate than the control group (treatment = 0%, control = 23.1%, p = 0.010). CONCLUSIONS In this pilot study, we found that the COACH caregiver support intervention successfully reduced EM of persons living with chronic illness, including dementia. Next steps will include: (1) testing the intervention's mechanism in a fully powered RCT and (2) scaling the intervention for testing in a variety of care delivery systems.

Abstract
Vibrio parahaemolyticus and Vibrio vulnificus are the leading causes of seafood-related illnesses and also can cause wound infections. These bacteria often co-exist in marine and estuarine environments. However, there have been no reported protocols that can detect and characterize (i.e. pathogenic or nonpathogenic) them in a single PCR. In this study, we developed a pPCR assay with a combination of two species-specific and three pathogenic-specific PCR primers to simultaneously detect virulent (viuB in V. vulnificus and tdh/trh in V. parahaemolyticus) and nonvirulent (vvhA in V. vulnificus and tlh in V. parahaemolyticus) markers of the two species in bacterial isolates. The assay was validated by three methods. First, the pPCR was used to characterize 300 bacterial isolates consisting of seven reference strains and 293 environmental strains isolated from the Gulf of Mexico water. Results were compared with characterizations based on single-gene PCR amplifications and previously published multiplex PCR protocols. Second, 51 isolates characterized with the pPCR were analysed by 16S rRNA sequencing to confirm any false-negative/positive reaction. Finally, the effectiveness of the assay for heterogeneous bacterial samples was validated. The pPCR correctly characterized isolates from the Gulf with an efficiency of 96·6-98·7%.

Abstract
The purpose of this study was to test the hypothesis that administration of epigallocatechin-3-gallate (EGCG), a polyphenol present in abundance in widely consumed tea, inhibits cell proliferation, invasion, and angiogenesis in breast cancer patients. EGCG in 400 mg capsules was orally administered three times daily to breast cancer patients undergoing treatment with radiotherapy. Parameters related to cell proliferation, invasion, and angiogenesis were analyzed while blood samples were collected at different time points to determine efficacy of the EGCG treatment. Compared to patients who received radiotherapy alone, those given radiotherapy plus EGCG for an extended time period (two to eight weeks) showed significantly lower serum levels of vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and reduced activation of metalloproteinase-9 and metalloproteinase-2 (MMP9/MMP2). Addition of sera obtained from patients treated with combination of radiotherapy and EGCG feeding for 2-8 weeks to in vitro cultures of highly-metastatic human MDA-MB-231 breast cancer cells resulted in the following significant changes: (1) suppression of cell proliferation and invasion; (2) arrest of cell cycles at the G0/G1 phase; (3) reduction of activation of MMP9/MMP2, expressions of Bcl-2/Bax, c-Met receptor, NF-κB, and the phosphorylation of Akt. MDA-MB-231 cells exposed to 5-10 µM EGCG also showed significant augmentation of the apoptosis inducing effects of γ-radiation, concomitant with reduced NF-κB protein level and AKT phosphorylation. These results provide hitherto unreported evidence that EGCG potentiated efficacy of radiotherapy in breast cancer patients, and raise the possibility that this tea polyphenol has potential to be a therapeutic adjuvant against human metastatic breast cancer.

Abstract
Floodwaters in New Orleans from Hurricanes Katrina and Rita were observed to contain high levels of fecal indicator bacteria and microbial pathogens, generating concern about long-term impacts of these floodwaters on the sediment and water quality of the New Orleans area and Lake Pontchartrain. We show here that fecal indicator microbe concentrations in offshore waters from Lake Pontchartrain returned to prehurricane concentrations within 2 months of the flooding induced by these hurricanes. Vibrio and Legionella species within the lake were more abundant in samples collected shortly after the floodwaters had receded compared with samples taken within the subsequent 3 months; no evidence of a long-term hurricane-induced algal bloom was observed. Giardia and Cryptosporidium were detected in canal waters. Elevated levels of fecal indicator bacteria observed in sediment could not be solely attributed to impacts from floodwaters, as both flooded and nonflooded areas exhibited elevated levels of fecal indicator bacteria. Evidence from measurements of Bifidobacterium and bacterial diversity analysis suggest that the fecal indicator bacteria observed in the sediment were from human fecal sources. Epidemiologic studies are highly recommended to evaluate the human health effects of the sediments deposited by the floodwaters.

Abstract
UNLABELLED Since the data investigating endovascular therapy performed by surgeons is scarce, we retrospectively reviewed our experience of endovascular procedures performed by vascular surgeons in the operating room for lower extremity ischemia due to stenotic lesions. METHODS A total of 14,424 procedures were performed by our division between January 1990--October 2003. Of these, 500 involved a balloon angioplasty. These made up 3.5% of the total caseload. The median age of the patients who underwent these 500 balloon angioplasty was 72+/-0.5 years old; 65% were male; 50% had a history of diabetes mellitus, and 6% had ESRD. Indications for the procedures included acute ischemia (47 cases), critical ischemia (rest pain, gangrene, or ischemic ulcers in 254 cases), failing bypass (64 cases), severe claudication (134 cases), and preoperative for a popliteal artery aneurysm repair. RESULTS 244 of the procedures were percutaneous, and the remaining 256 were combined with some type of open procedure. Those performed as an open technique were in combination with a bypass (135 cases) and in combination with a patch angioplasty (31cases). Balloon angioplasties were performed of the aorta (5 cases), iliac arteries (281 cases), the superficial femoral artery (SFA) (101 cases), the popliteal artery (44 cases), the tibial vessels (77 cases), the subclavian/axillary artery (5 cases) and failing grafts (26 cases). Balloon angioplasty was attempted in eight cases and failed due to inability to cross the lesion with a guidewire. Intraoperative complications included 4 dissections, inability to dilate the lesion adequately (2 cases), and rupture of two iliac lesions that underwent open repair (1 case) or repair with a stent graft (1 case). Stents were initially used highly selectively but recently are now being deployed more liberally in the iliac arteries (total 251 cases with stents). CONCLUSIONS Based on these data, we suggest that balloon angioplasty is a useful tool that can be performed by vascular surgeons safely. The advantages to the patients include one combined procedure to treat lower extremity ischemia.

Abstract
Four new benzophenones with two isoprenoid groups, cudraphenones A-D (1-4), and three new xanthones also with two isoprenoid units, cudraxanthones P-R (5-7), were isolated from the roots of Cudraniacochinchinensis, together with 19 known phenolic compounds. The structures of the new compounds were elucidated by spectroscopic methods. Some compounds exhibited weak cytotoxicity against human oral squamous carcinoma cells (HSC-2) and normal human gingival fibroblasts (HGF). Among them, benzophenones 1-4 showed more potent cytotoxic activities against HSC-2 cells than against HGF cells. On the other hand, xanthones bearing isoprenoid groups showed much lower tumor specificity as compared with the benzophenones, except for geronthxanthone H and isoalvaxanthone. The presence of two sets of hydrophobic and hydrophilic groups in separate domains in each molecule might play a role in the mediation of tumor-specific action.

Abstract
An infant with multiple anomalies including small head, large apparently low-set ears, beaked nose, micrognathia, choanal stenosis, proptosis, atrial-septal defect, and left inguinal hernia was found, on chromosome analysis, to have a longer than normal terminal band 4p16 by G and R-banding. In situ hybridization of biotin-labeled DNA probes C39, BJ14, BJ54, BJ19, BJ7, and BJ11 showed them to be duplicated. Probes I14, A157.1, and the telomeric sequence, (TTAGGG)n, which hybridized to the more distal part of 4p16.3, were not duplicated. These results confirm the impression by G and R-banding of a duplication within band 4p16, a region extending from approximately 2.1 Mb from the telomere, proximally, to the junction of 4p16.1 and 4p15.3. This is the smallest confirmed duplication of distal 4p reported to date, with many of the classical findings of dup(4p) syndrome.
