Social exclusion of those with criminal justice experience increasingly includes a financial component, but the structure of disadvantage in credit and debt remains unclear. We develop a model of financial disadvantage in debt-holding during the transition to adulthood among justice-involved groups. We study cumulative criminal justice contact and debt holding by age thirty using the NLSY97.

Activities of daily living can be affected by cognitive decline. Self-report measurement of functioning is attractive due to ease of data collection, low cost, and accessibility via technology-assisted means, and for understanding patient perspective. A concern is with reliability of such measurement as cognitive decline occurs.

Purpose: We evaluated the efficacy of gemcitabine versus gemcitabine and carboplatin in patients with advanced non-small-cell lung cancer (NSCLC) and a performance status (PS) of 2 and assessed if tumoral RRM1 and ERCC1 protein levels are predictive of response to therapy.

Patients And Methods: A randomized phase III trial was conducted in community-based oncology practices. Tumor specimens were collected a priori and shipped to a single laboratory for blinded determination of in situ RRM1 and ERCC1 protein expression levels by an automated quantitative immunofluorescent-based technology.

The molecular basis for sporadic Alzheimer disease (AD) remains largely unknown. We hypothesized that in some cases of sporadic AD, a somatic mutation in an embryonic cell committed to neuronal development within the amyloid precursor protein (APP), the presenilin 1 (PS-1) or the presenilin 2 (PS-2) genes (genes known to be involved in familial AD) may result in AD phenotype. Using PCR, denaturing gradient gel electrophoresis (DGGE), restriction enzyme digest and direct DNA sequencing, we analyzed these genes in 99 brain tissues from patients with histopathologically proven AD.

Nephrogenic diabetes insipidus (NDI) is a rare disease characterized by renal inability to respond properly to arginine vasopressin due to mutations in the vasopressin type 2 receptor (V2(R)) gene in affected kindreds. In most kindreds thus far reported, the mode of inheritance follows an X chromosome-linked recessive pattern although autosomal-dominant and autosomal-recessive modes of inheritance have also been described. Studies demonstrating mutations in the V2(R) gene in affected kindreds that modify the receptor structure, resulting in a dys- or nonfunctional receptor have been described, but phenotypically indistinguishable NDI patients with a structurally normal V2(R) gene have also been reported.

Carcinoid tumors are neuroendocrine neoplasms that are encountered either sporadically or as part of a familial syndrome, most notably-multiple endocrine neoplasia type 1 (MEN1). The MEN1 gene localizes to chromosome 11 (11q13) and presumably functions as a tumor suppressor gene. The molecular mechanisms underlying carcinoid tumor development and their clonal composition remain largely unknown.

Cardiac myxomas are rare tumors that may be encountered sporadically or in the context of the Carney complex. The molecular basis for the development of cardiac myxomas and Carney complex tumors is unclear. Pathological myocardial function and myocardial hypertrophy have been associated with alterations in the heterotrimeric GTP-binding proteins.

The normally developing placenta undergoes extensive but regulated noninvasive cellular proliferation. Various proto-oncogenes and growth factors have been associated with the regulation of trophoblastic placental growth. Activation of some oncogenes and altered expression of growth factors have been demonstrated in trophoblastic tumors (hydatidiform mole and choriocarcinoma).

Zeniplatin, a more water-soluble organoplatinum than cisplatin, was evaluated for clinical pharmacology in the context of a phase II trial in previously treated patients with ovarian carcinoma. A total of 12 patients were given zeniplatin at 120 mg/m2 by rapid intravenous infusion over 90 min, with both blood and urine being sampled. All platinum moieties were analyzed in whole blood, plasma, plasma ultrafiltrate, and urine by atomic absorption, and free zeniplatin was analyzed in plasma ultrafiltrate by specific high-performance liquid chromatography (HPLC).

Eight patients, of whom four had acute myeloid leukemia (AML) and four had chronic myeloid leukemia (CML) blast crisis, were treated with a combination of cytosine arabinoside (ARA-C: 1,600 mg/m2 in three patients, 1,200 mg/m2 in five patients), tetrahydrouridine (THU: 2,800 mg/m2 in two patients, 2,646 mg/m2 in one patient, 2,100 mg/m2 in five patients), and carboplatin (900 mg/m2 in four patients, 720 mg/m2 in one patient, 450 mg/m2 in three patients). As a result of this treatment, five of the eight patients became aplastic. Two of the four patients with CML blast crisis reverted to the chronic phase and two of the four patients with acute nonlymphocytic leukemia (ANLL) attained a remission (one partial remission and one complete remission).

There is a critical need to find new chemotherapeutic agents that are active in platinum-refractory ovarian cancer. A phase II trial of zeniplatin (CL 286,558), a third-generation platinum compound, was conducted in 31 patients with advanced ovarian cancer to examine the safety and activity of the agent when used as a salvage treatment in individuals previously exposed to organoplatinum-based therapy. In general the drug was well tolerated, with moderate emesis and bone marrow suppression being observed in most patients.

Radical therapy for locally advanced or recurrent gynecologic malignancies (LARGM) may include interstitial brachytherapy (IB) when intracavitary brachytherapy is impossible or inadequate and external beam teletherapy would be limited by surrounding normal tissue tolerance. Sixteen women received IB as all or part of their treatment at North Shore University Hospital for the treatment of locally advanced primary or recurrent tumors of gynecologic origin from May 1988 through September 1990. Primary sites included the vulva (3), vagina (2), cervix (7), and endometrium (4).

The ageing of the population has resulted in a greater emphasis on cancer treatment effects in elderly patients. This population has often had arbitrary dose modification of chemotherapy owing to fear of excessive side-effects. A review was undertaken to evaluate cisplatin toxicity in patients of 70 years of age or older.

The aims of this study were to: a) Identify factors reflecting reasons for drinking and expectancies regarding the effects of drinking among inpatient alcoholics; b) Examine the relationship between these cognitive "motivations" for drinking and both patterns of alcohol consumption and various personal and social consequences of consumption. The factors which emerged relate to negative mood reduction, positive mood enhancement, and social functioning. Although the factors identified in this investigation were not associated with quantity of alcohol consumed, small to moderate associations were found between scores on three of four factors and a variety of adverse physical and occupational consequences of alcohol abuse.

Variant translocations involving either chromosome 9, chromosome 22, or both with other chromosomes have been reported in about 8% of chronic myelogenous leukemia (CML) patients. In the 22 Ph+ patients studied in our laboratory, two showed variant translocations: t(9;22;11) (q34;q11;q13), and t(9;11) (q34;q11). We compared the pattern of involvement of different chromosomes (and bands) in secondary structural changes in CMLs carrying the t(9;22) (q34;q11) and in the variant translocations.

Fibrin formed on endothelial cells has previously been shown to have deleterious effects on the cells. Additionally, substances that cause endothelial cell damage have been reported to induce cultured endothelial cells to synthesize prostacyclin and tissue plasminogen activator (t-PA). The present studies were undertaken to determine whether fibrin formed on cultured human umbilical vein endothelial cells would alter synthesis of prostacyclin and t-PA by the cells.
