Victim Help Seeking: Differences Between Intimate Terrorism and Situational Couple Violence

Abstract: Research indicates that two major forms of partner violence exist, intimate terrorism (IT) and situational couple violence (SCV). The current study (N= 389) used a subgroup of women who responded to the Chicago Women’s Health Risk Study to examine whether type of violence experienced is differentially related to formal (e.g., police, medical agencies, counseling) and informal (e.g., family, friends/neighbors) help seeking. IT victims were more likely to seek each type of formal help but were equally or less likely to seek informal help. Findings can inform both family violence research and the development and implementation of social service programs.     

Small cell carcinoma of the cervix: a clinical and flow-cytometric study.

The clinical course of 14 patients diagnosed with small cell carcinoma of the cervix (SCC) was reviewed and compared to that of 37 cases of undifferentiated large cell nonkeratonizing carcinoma (LCNK). We observed the following differences between the two: SCC patients had a higher incidence of pelvic wall involvement and distant metastasis; the development of progressive disease was more frequent in SCC than in LCNK patients; median survival time was 9 months in SCC and 40 months in LCNK patients; flow cytometry revealed aneuploidy in all SCC and in 30% of the LCNK patients; the mean DNA index was 2.24 in SCC, significantly higher than in LCNK (1.15). DNA index in cases of SCC was related to survival time. SCC of the cervix is an extremely aggressive tumor, even when compared to other undifferentiated cervical cancers. Aneuploidy is a consistent feature and thus helpful for diagnosis. Due to the wide range of values, the DNA index cannot be used for diagnostic purposes, but it is of prognostic importance in SCC cases.     

Evaluation of a new molecular assay for detection of human immunodeficiency virus type 1 RNA, hepatitis C virus RNA, and hepatitis B virus DNA.

BACKGROUND: Rapid, sensitive, specific, and cost-effective screening of donated blood to prevent transmission of infectious agents remains challenging. In recent years, incorporation of nucleic acid testing for HIV-1 and HCV RNA improved blood safety by reducing the window period between infection and serologic detection. For HBV infection, this window period with most serologic assays is 50-60 days. Adding a nucleic acid test (NAT) for HBV DNA with existing NATs for HIV-1 and HCV RNA would further improve blood safety and blood screening efficiency. OBJECTIVE: To evaluate the Procleix Ultrio Assay for simultaneous detection of HIV-1 and HCV RNA and HBV DNA and corresponding discriminatory assays. STUDY DESIGN: The performance of these assays, which utilize the same technology and assay format as the Procleix HIV-1/HCV assay, was determined using relevant clinical specimens and analytical sensitivity and specificity panels. RESULTS: The Procleix Ultrio Assay demonstrated specificity of > or =99.5% in healthy donor blood specimens and in plasma containing potentially interfering substances or other blood-borne pathogens. Assay sensitivity demonstrated >95% detection of 100copies/mL, 30IU/mL, and 15IU/mL for HIV-1 and HCV RNA, and HBV DNA, respectively. The assay detects all known HIV-1 subtypes and HCV and HBV genotypes and is highly reproducible. Statistical analysis using receiver operating characteristic plots demonstrated wide analyte cutoff values for each assay associated with assay specificity and sensitivity of > or =99.5%. CONCLUSIONS: In this investigational study, the Procleix Ultrio Assay sensitivity and specificity were similar to existing NATs used in blood-bank settings to detect HIV-1 and HCV RNA and provided equivalent sensitivity and specificity for detection of HBV DNA. Using this combination assay, blood safety may be improved and the multiplex format enhances blood screening efficiency. The throughput capability of this assay is compatible with large volume processing and the chemistry is adaptable to full automation.     

Erythrocyte homeostasis: antibody-mediated recognition of the senescent state by macrophages.

We tested the hypothesis that the accumulation of bound autologous antibody on a "senescent epitope" identifies aged erythrocytes for phagocytic removal by macrophages. Erythrocytes were collected from mice maintained on a hypertransfusion protocol designed to yield cells of defined age. The mouse erythrocytes were assayed for the presence of bound antibody by measuring their susceptibility to ingestion by macrophages from mouse peritoneal exudates and by flow cytofluorometry. Both assays disclosed that only the oldest mouse erythrocytes bore detectable levels of antibody. Flow cytofluorometric analysis revealed that the frequency distribution of IgG isotypes bound to the cells reflected their levels in normal serum. Finally, treatment with trypsin abolished the ability of the macrophages to ingest erythrocytes aged in vivo. These findings support the hypothesis that antibody mediates the clearance of senescent mouse erythrocytes from the circulation and demonstrate that the presence of a trypsin-sensitive recognition structure on macrophages is an essential requirement in this homeostatic process.

Hereditary Spastic Paraplegia Type 43 (SPG43) is Caused by Mutation in C19orf12

We report here the genetic basis for a form of progressive hereditary spastic paraplegia (SPG43) previously described in two Malian sisters. Exome sequencing revealed a homozygous missense variant (c.187G>C; p.Ala63Pro) in C19orf12, a gene recently implicated in neurodegeneration with brain iron accumulation (NBIA). The same mutation was subsequently also found in a Brazilian family with features of NBIA, and we identified another NBIA patient with a three‐nucleotide deletion (c.197_199del; p.Gly66del). Haplotype analysis revealed that the p.Ala63Pro mutations have a common origin, but MRI scans showed no brain iron deposition in the Malian SPG43 subjects. Heterologous expression of these SPG43 and NBIA variants resulted in similar alterations in the subcellular distribution of C19orf12. The SPG43 and NBIA variants reported here as well as the most common C19orf12 missense mutation reported in NBIA patients are found within a highly conserved, extended hydrophobic domain in C19orf12, underscoring the functional importance of this domain.     

A Voice-Based Computer Interview for Drug Dependence

Abstract

The Recovery Attitudes and Treatment Evaluator (RAATE), via 94 true/false questions, assesses resistance and obstacles to chemical dependence treatment. We computerized the RAATE to offer questions via digitized human voice and to recognize patient responses spoken into the computer's microphone. Sixty-eight consecutive adults seeking addictions treatment were randomized to one of four formats. The voice-input/voice-output version yielded the shortest mean duration of administration. Patients reported high satisfaction ratings and confidence that their answers were accurate. They perceived their responses to be useful in treatment planning. Group mean ratings did not significantly differ by version. There was a statistical trend in which the voice-based versions reduced the intragroup variability on test duration and patient confidence. Computerized voice-interactive interviewing may shorten test durations, increase the uniformity of administration, increase access for the vision-impaired, and increase the data entry efficiency and accuracy. The method provides a consistent, controlled, and nonjudgmental interview interaction.     

Determination of chymotrypsin in the feces by a new photometric method

Fecal chymotrypsin (FCT) was determined in stool specimens of healthy children and those with gastro-intestinal disease, by a new photometric method. The values are comparable with chymotrypsin concentrations found by pH-stat method. The new test is cheap, reliable and easy to perform. For this reasons and for the sensitivity of all tubeless pancreatic function tests (NBT-PABA, FDL, FCT) is rather low (60-70%), the FCT-test may be preferred as diagnostic marker for differential diagnosis of exocrine pancreatic insufficiency.
