Polyvictimization and Psychiatric Sequelae Associated with Female Genital Mutilation/Cutting (FGM/C)

Female Genital mutilation/cutting (FGM/C) is associated with enduring psychiatric complications. In this study, we investigate the rates of co-morbid abuses and polyvictimization experienced by survivors of FGM/C. This is a sub-analysis of a cohort study examining the patient population at the EMPOWER Center for Survivors of Sex Trafficking and Sexual Violence in New York City. A retrospective chart-review of electronic medical records was conducted for all consenting adult patients who had FGM/C and had an intake visit between January 16, 2014 and March 6, 2020. Of the 80 participants, ages ranged from 20 to 62 years with a mean of 37.4 (SD?=?9.1) years. In addition to FGM/C, participants were victims of physical abuse (43; 53.8%), emotional abuse (35; 43.8%), sexual abuse (35; 43.8%), forced marriage (20; 25%), child marriage (13; 16.3%), and sex trafficking (1; 1.4%). There was a high degree of polyvictimization, with 41 (51.2%) experiencing 3 or more of the aforementioned abuses. Having FGM/C on or after age 13 or having a higher total abuse score was also found to be strong predictors of depression and PTSD. The high rates of polyvictimization among survivors of FGM/C are associated with development of depression and PTSD. Despite co-morbid abuses, patients still attribute substantial psychiatric symptoms to their FGM/C. Health care providers should understand the high risk of polyvictimization when caring for this patient population.

     

Estimates of disease incidence in women based on antenatal or neonatal seroprevalence data: HIV in new york city

Piecewise constant incidence models were developed to estimate the force of infection in women from age-and time-specific antenatal or neonatal seroprevalence data. Differential inclusion of infected women in sero-surveys compared to uninfected women was taken into account, with respect to both changes in inclusion rate following infection, and changes in relative inclusion rate over calendar time. These models were applied to anonymous HIV seroprevalence data collected from neonates born to black and Hispanic women in New York City 1988-1992, with incidence and fertility parameters estimated by maximum likelihood. Estimates of inclusion rate parameters accorded well with what is known about the natural history of HIV. The data could not distinguish between additive and multiplicative combination of the effects of age and time on incidence. Incidence was strongly dependent on age with the highest incidence in women aged 20-34 years. There was strong evidence that incidence had been falling in Hispanic women since 1982-1984. The results illustrate the extent to which trends in incidence over time may be confounded by changes in the relative inclusion rate of infected and uninfected women.     

"In vivo effects of rIL-2 pretreatment on chemotherapeutically induced in vivo natural cytolytic hyporesponsiveness"

Chemotherapeutics have been shown to have detrimental effects on immune response, hence, pretreatment or concurrent use of an immune augmentation substance could lead to reconstitution of an immune response such as cytolytic activity after administration of chemotherapeutic agent. Previously, in an in vitro system, we have demonstrated IL-2 pretreatment reconstituted drug induced immunosuppression as well as altered differential sensitivities to chemotherapeutic agents. This study presents evidence that in vivo functional cytolytic potential can be retained by IL-2 pretreatment on chemotherapeutically-induced natural cytolytic hyporesponsiveness.     

Retention of "safe" blood donors. The Retrovirus Epidemiology Donor Study

BACKGROUND: There are obvious advantages to increasing donor retention. However, for reasons of blood safety, certain donors may, in fact, be more desirable to retain than others. “Safe” donors are defined as those who provided a blood donation that was negative on all laboratory screening tests and who subsequently reported no behavioral risks in response to an anonymous survey. This study identifies the most important factors affecting the intention of “safe” donors to provide another donation. STUDY DESIGN AND METHODS: An anonymous survey asking about donation history, sexual history, injecting drug use, and recent donation experience was mailed to 50,162 randomly selected allogeneic donors (including directed donors) who gave blood from April through July or from October through December 1993 at one of the five United States blood centers participating in the Retrovirus Epidemiology Donor Study. Before mailing, questionnaires were coded to designate donors with nonreactive laboratory screening tests at their most recent donation. RESULTS: A total of 34,726 donors (69%) responded, with substantially higher response among repeat donors. According to reported intentions only, the vast majority of “safe” donors indicated a high likelihood of donating again within the next 12 months. Only 3.4 percent reported a low likelihood of donating again. A comparison of those likely to return and those unlikely to return reveals significant differences in demographics and in ratings of the donation experience. A higher proportion of those unlikely to return were first-time donors, minority-group donors, and donors with less education. The highest projected loss among “safe” donors was seen for those who gave a fair to poor assessment of their treatment by blood center staff or of their physical well-being during or after donating. CONCLUSION: These data suggest that efforts to improve donors' perceptions of their donation experience, as well as attention to the physical effects of blood donation, may aid in the retention of both repeat and first-time donors.     

Protective effect(s) of rIL-2 modulation. I. The effects of chemotherapeutic/cytotoxic agents on human natural killer cells and lymphokine-activated killer cells

This study investigated whether in vitro immunotherapy with rIL-2 which augments human natural cytotoxicity and generation of lymphokine-activated killer cells diminished or inhibits the severity of therapeutically induced human in vitro NK immunosuppression. We demonstrate that rIL-2 induces a rapid and potent enhancement of cytolytic killing and that pretreatment of effector cells for one hour with rIL-2 yields effector cells which are more resistant to drug-induced immunosuppression. Additionally, we demonstrate cells pretreated for 24 hours with rIL-2 were less sensitive to drug inhibitory effects than rIL-2 non-treated or one hour pretreated effector cells. Our data suggest prophylactic treatment with IL-2 for drug induced immunosuppression is feasible.     

Age-related reference ranges: Significance tests for models and confidence intervals for centiles

A method of fitting age-related reference ranges using maximized likelihood is presented. The method is illustrated using CD4 counts of uninfected children born to HIV-1 infected women. The likelihood incorporates exponential functions to describe the Box-Cox transformation parameter that induces Normality and the mean and standard deviation of the transformed data, at all ages in the range. This guarantees that the centiles are asymptotic to notional adult values and avoids edge effects. Likelihood ratio tests were used to assess the significance of the model parameters, and profile likelihood confidence intervals were constructed around the fitted centiles. The asymptotes of the resulting CD4 reference range for the childhood dataset were compared with CD4 counts available from a group of uninfected adults. The proposed approach limits the need for arbitrary decisions about grouping of the data, degree of smoothing or choice of model.     

Obstetric and perinatal consequences of human immunodeficiency virus (HIV) infection: a review

Pediatric acquired immune deficiency syndrome (AIDS) was known to be a new disease that could be acquired from the mother even before human immunodeficiency virus (HIV) was identified. The suggested routes of transmission of infection are intrauterine, perinatal--from contact with infected maternal genital secretions, or through breastfeeding. At this time the problem in Europe concerns primarily women in high-risk groups: intravenous drug abusers, prostitutes, women from countries where the prevalence of HIV is high, and women whose sexual partners are in a high-risk group. In the future, the infection may extend beyond women in high-risk groups as the disease becomes more prevalent in the community. It has been claimed that pregnancy accelerates symptoms in women who are HIV positive, yet this is based on only a series of case reports of severe infection in pregnancy and on the development of AIDS in asymptomatic women in pregnancy subsequent to the birth of an AIDS child. The only data capable of shedding some light on this issue would be a prospective followup of both pregnant and nonpregnant HIV-positive women from similar high-risk groups. Such a study is ongoing in the US. An increasing number of case reports suggest intrauterine transmission of infection. The following 3 case reports provide clear evidence of intrauterine transmission. Sprecher et al. (1986) detected HIV antigen in amniotic fluid and fetal tissues from a pregnancy termination at 15 weeks gestation in a woman with stage IV AIDS and Kaposi sarcoma. Lapointe et al. (1985) reported an infant born by cesarean section at 28 weeks gestation to a mother with terminal aids. A new dysmorphic syndrome recently has been described in children with symptomatic HIV infection (Marion et al., 1986). HIV has been isolated from cervical secretions (Fogt et al., 1986; Wofsy et al., 1986), which suggests that this cold be another source of infection. There is 1 report of isolation of HIV from the noncellular fraction of breast milk (Thirty et al., 1985). Several case reports have described acquired immunodeficiency in infants for whom the only known risk factor was neonatal transfusion from an individual later found to be suffering from AIDS. The risk of transmission from an infected mother to her infant is unknown, but the best available evidence comes from a study of children born to women who had previously given birth to a child with AIDS (Scott et al, 1985). Of 12 children, 4 developed AIDS or Aids-related complex. Clinical problems among children with AIDS or AIDS-related complex have been fully described. The fatality rate of children with AIDS is high, but the ultimate progress of children with less severe disease or who have asymptomatic infection is known.     

Frequent ongoing T-cell receptor rearrangements in childhood B- precursor acute lymphoblastic leukemia: implications for monitoring minimal residual disease

Crosslineage T-cell receptor delta (TCR delta) rearrangements are widely used as tumor markers for the follow up of minimal residual disease in childhood B-precursor acute lymphoblastic leukemia (ALL) by polymerase chain reaction (PCR). The major drawback of this approach is the risk of false-negative results due to clonal evolution. We investigated the stability of V delta 2D delta 3 rearrangements in a group of 56 childhood B-precursor ALL patients by PCR and Southern blot analysis. At the PCR level, V delta 2D delta 3-to-J alpha rearranged subclones (one pathway for secondary TCR delta recombination) were demonstrated in 85.2% of V delta 2D delta 3-positive patients tested, which showed that small subclones are present in the large majority of patients despite apparently monoclonal TCR delta Southern blot patterns. Sequence analysis of V delta 2D delta 3J alpha rearrangements showed a biased J alpha gene usage, with HAPO5 and J alpha F in 26 of 32 and 6 of 32 clones, respectively. Comparison of V delta 2D delta 3 rearrangement status between diagnosis and first relapse showed differences in seven of eight patients studied. In contrast, from first relapse onward, no clonal changes were observed in six patients studied. To investigate the occurrence of crosslineage TCR delta rearrangements in normal B and T cells, fluorescence-activated cell sorter-sorted peripheral blood CD19+/CD3- and CD19-/CD3+ cell populations from three healthy donors were analyzed. V delta 2D delta 3 rearrangements were detected at low frequencies in both B and T cells, which suggests that V delta 2-to-D delta 3 joining also occurs during normal B-cell differentiation. A model for crosslineage TCR delta rearrangements in B-precursor ALL is deduced that explains the observed clonal changes between diagnosis and relapse and is compatible with multistep leukemogenesis of B-precursor ALL.     

Indomethacin increases the effect of isosorbide dinitrate on cerebral hemodynamic in migraine patients: pathogenetic and therapeutic implications

Intracerebral vascular reactivity induced by the nitric oxide (NO) donor isosorbide dinitrate (IDN, 5 mg sublingually) is more major and longer-lasting in migraine patients who develop delayed headache in response to the drug. The headache is purportedly due to neuronally-mediated vascular mechanisms. Indomethacin inhibits prostaglandin synthesis, which is involved in NO generation. Indomethacin also decreases cerebral blood flow by constricting precapillary resistance vessels. In the present study, the hemodynamic effects of indomethacin were evaluated in migraine patients and healthy controls by means of transcranial Doppler monitoring. Indomethacin caused a significant decrease in mean flow velocity in the middle cerebral artery. This was an additional effect to the mean velocity decrease induced by IDN. The interactions between the two drugs suggest that their effects on cerebral hemodynamics (and pain) may be of relevance both in understanding the role of NO in migraine pathogenesis and in evaluating symptomatic treatments for migraine attacks.
