RESUMO

The family members of death row inmates undergo unique suffering that includes disenfranchised grief and intense psychological trauma. In Texas, where executions occur at a rate of 1 every 2 weeks, this class of trauma victims presumably is large, a fact that should generate public mental health concern. Yet the class remains virtually unknown to the therapeutic community. Very little has been done to address the trauma healing needs of death row families. This theoretical paper proposes that structural therapy designed to reengage attachment relationships and reempower family members' innate resources to emotionally regulate one another may provide one of the most effective means of helping this population survive trauma.

RESUMO

Mantle cell lymphoma (MCL) is challenging to manage, with a median survival of 3-5 years. While intensive strategies are often appropriate for younger patients, these approaches are often not appropriate for older patients. In 2006, we reported our initial results using modified R-hyperCVAD (rituximab with hyperfractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone) with maintenance rituximab. The complete response rate was 64%, and median progression-free survival (PFS) 37 months. Herein, we update our results, now with a median follow-up of 62 months. The median PFS is unchanged and the median overall survival (OS) is 70 months. The proportion of patients surviving at 5 years is 62%, comparable to studies using intensive strategies in similar patient populations. No late toxicities were noted in our cohort. These long-term results suggest that the modified R-hyperCVAD regimen with maintenance rituximab is an excellent option for older patients with newly diagnosed mantle cell lymphoma.

RESUMO

OBJECTIVE: We hypothesized that intracoronary adenoviral-mediated delivery of betaARKct would improve heart failure associated pathophysiologic abnormalities related to exercise capacity, cardiac contractility, systemic inflammation and volume overload. METHODS: After aortic banding, a cohort of Sprague-Dawley rats was followed by echocardiography. When an absolute decline of 25% in fractional shortening was detected, animals were randomized to intracoronary delivery of Ad.ssARKct (n=14), Ad.beta-Gal (n=13), or followed without any other further intervention (n=18). Assessment of exercise tolerance and hemodynamic profile and measurement of markers of systemic inflammation and volume overload was performed at 7, 14, and 21 days after gene delivery. Data were analyzed using ANOVA. RESULTS: Animals receiving Ad.ssARKct showed improved exercise tolerance compared to Ad.Gal-treated animals at 14 days (507+/-26 s vs. 408+/-19 s, P=0.01) and 21 days (526+/-55 s vs. 323+/-19 s, P<0.001) following injection. Animals receiving Ad.ssARKct demonstrated improved +dP/dtmax (mean+/-SD, 5,581+/-960 mmHg/s vs. 3,134+/-438 mmHg/s, P<0.01) and -dP/dtmax (mean+/-SD, -3,494+/-1,269 mmHg/s vs. -1,925+/-638 mmHg/s, P<0.01) compared to Ad.Gal-treated animals at 7 days. These differences were observed up to 21 days following injection. Serum levels of IL-1, IL-6, and TNF-alpha, as well as ANP were also decreased in animals receiving Ad.betaARKct. CONCLUSIONS: Genetic modulation of heart failure using the betaARKct gene was associated with improved exercise capacity and cardiac function as well as amelioration in heart failure-associated profiles of systemic inflammation and volume overload.

RESUMO

BACKGROUND: We hypothesized that sarcoplasmic reticulum Ca2+ ATPase pump (SERCA-2a) gene delivery would have beneficial effects upon exercise capacity and markers of inflammation in the setting of heart failure. MATERIALS AND METHODS: A pressure-overload model of experimental heart failure was used in rats. Following a decrease in fractional shortening of >or=25%, animals underwent intracoronary adenoviral-mediated gene transfection using SERCA-2a. Heart failure animals were randomized to receive the SERCA-2a gene, the beta galactosidase (control) gene, or followed without any further intervention. Exercise and hemodynamic testing were performed, and myocardial and systemic markers of inflammation were assayed after 7 and 21 d. RESULTS: Animals receiving Ad.SERCA-2a showed an increase in exercise tolerance (499.0 +/- 14.9 versus 312.8 +/- 10.5 s, P < 0.0001) relative to Ad.Gal group. Groups treated with Ad.SERCA-2a had significantly decreased serum levels of the inflammatory markers interleukin-1, interleukin-6, and tumor necrosis factor-alpha compared with Ad.Gal-treated animals. Serum levels of atrial natriuretic peptide were decreased in animals receiving Ad.SERCA-2a compared with animals receiving Ad.Gal at day 7 (0.35 +/- 0.03 versus 0.52 +/- 0.11 pg/mL, P = 0.001). Myocardial levels of the proapoptotic protein bax were reduced in Ad.SERCA-2a -treated animals compared with those receiving Ad.Gal at day 7 (protein level/actin: 0.24 +/- 0.05 versus 0.33 +/- 0.04, P = 0.04) and day 21 (protein level/actin: 0.61 +/- 0.04 versus 0.69 +/- 0.01, P = 0.001). CONCLUSIONS: Genetic modulation of heart failure using the SERCA-2a gene was associated with improvement in cardiac function and exercise capacity as well as improvements in heart-failure associated inflammatory markers.

RESUMO

Multiple myeloma (MM), a B-cell malignancy characterized by proliferation of monoclonal plasma cells remains incurable. Murine plasma cell tumors share common features with human MM. We used two cell lines (B38 and C11C1) derived from P3X63Ag8 myeloma cells. The new cell lines were implanted subcutaneously in the strain of origin (Balb/c mice) and used as a model to monitor the effects of C11C1 monoclonal antibody (mAb) to kininogen (HK). We assessed their behavior by intraperitoneal and subcutaneous implantation, by implanting them together and by treating B38-MM with purified mAb C11C1. We evaluated growth, microvascular density (MVD), and cellular expression of urokinase-type plasminogen activator-receptor (uPAR), fibroblast growth factor-2 (FGF-2), vascular endothelial growth factor (VEGF), bradykinin-1 receptor (B1R), bradykinin-2 receptor (B2R) and HK. We found that both MM-cell-lines are uPAR positive, that mAb C11C1 inhibits its own tumor growth in vivo, slows down B38-MM growth rate when both MM are implanted together and when mAb C11C1 is injected intraperitoneally. MAb C11C1-treated-MM showed decreased MVD and HK binding in vivo without FGF-2, B1R or B2R expression changes. We propose that the B38-extramedullary-myeloma-model is a useful tool to study the interactions of this hematopoietic tumor and its environment and that mAb C11C1 may improve the efficacy of conventional MM treatment with minimal side effects.

RESUMO

PURPOSE: Transforming growth factor-beta1 plays a central role in colonic repair. We examined the temporal effect of vector-mediated transfer of transforming growth factor-beta1 on colonic anastomotic healing. METHODS: Male Sprague-Dawley rats (n = 24) underwent transection of the distal colon and single-layer anastomosis. Proximal to the anastomosis, the colon was again transected and a colostomy was matured proximally. The distal colon was intubated with a silicone catheter, tunneled along subcutaneous tissues, and connected to a swivel apparatus for postoperative luminal infusion. Rats were randomized into four groups (n = 6 each). Two control groups received 10(10) plaque-forming units of a Type 5 E1-deleted adenovirus carrying the bacterial beta-galactosidase gene either immediately following surgery or on postoperative Day 3. The treatment groups received transforming growth factor-beta1 with the same viral construct at parallel time points. On postoperative Day 6, anastomotic bursting pressure and site were determined in situ with the anastomotic tissue subsequently harvested and analyzed by enzyme-linked immunosorbent assay for beta-galactosidase and transforming growth factor-beta1. RESULTS: When compared with its corresponding control, the group that received the transforming growth factor-beta1 gene on postoperative day 3 had a significantly higher bursting pressure (mmHg; 119 +/- 16 vs. 160 +/- 12, mean +/- SD; P = 0.001). While the majority of colons (5/6) from the control group burst at the anastomosis, none of the colons in the group that received transforming growth factor-beta1 on day 3 burst at the anastomotic site (P = 0.007). Beta-Galactosidase levels (pg/ml) in anastomotic tissue were significantly increased in both control groups when compared with their respective treatment groups (101 +/- 43 vs. 38 +/- 30, P = 0.01 when infused the day of surgery and 243 +/- 92 vs. 50 +/- 30, P = 0.009 when infused on day 3). Anastomotic levels of transforming growth factor-beta1 were also increased in the group receiving the transforming growth factor-beta1 gene on day 3 (214 +/- 66 vs. 135 +/- 24, P = 0.02). CONCLUSIONS: Gene transfer into the healing colonic anastomosis can be effectively achieved via intraluminal administration of adenoviral vectors. Transfer of transforming growth factor-beta1 increased the strength of colonic anastomoses when given at Day 3 but not at Day 0, demonstrating its diverse effects in the wound healing sequence. Thus, gene transfer of transforming growth factor-beta1 may avoid the need for a diverting stoma in cases of rectal surgery and impaired healing resulting from chemotherapy or radiation.

RESUMO

We reported that high-molecular weight kininogen is proangiogenic by releasing bradykinin and that a monoclonal antibody to high-molecular weight kininogen, C11C1, blocked its binding to endothelial cells. We now test if this antibody can prevent arthritis and systemic inflammation in a Lewis rat model. We studied 32 animals for 16 days. Group I (negative control) received saline intraperitoneally. Group II (disease-treated) received peptidoglycan-polysaccharide simultaneously with C11C1. Group III (disease-untreated) received peptidoglycan-polysaccharide simultaneously with isotype-matched mouse IgG. Group IV (disease-free-treated) and group V (disease-free isotype-treated) received saline and C11C1 or mouse IgG. Analysis of joint diameter changes showed a decrease in the C11C1 disease-treated group compared to the disease-untreated group. The hind paw inflammatory score showed a decrease in the intensity and extent of inflammation between the disease-untreated and the C11C1 disease-treated group. Prekallikrein, high-molecular weight kininogen, factor XI, and factor XII were decreased in the disease-untreated group compared to the C11C1 disease-treated group. T-kininogen was increased in the disease-untreated group when compared with the C11C1 disease-treated group. Disease-free groups IV and V did not show any sign of inflammation at any time. This study shows that monoclonal antibody C11C1 attenuates plasma kallikrein-kinin system activation, local and systemic inflammation, indicating therapeutic potential in reactive arthritis.
