Perception of sexuality and fertility in women living with HIV: a questionnaire study from two Nordic countries

Introduction

As the human immunodeficiency virus (HIV)-positive population ages, issues concerning sexuality and fertility, among others, are becoming relevant. HIV is still surrounded by stigma and taboos, and there have been few studies conducted in industrialized settings concerning these questions. We therefore wanted to investigate the perception of sexuality and fertility in women living with HIV (WLWH) in an industrialized setting, using a questionnaire.

Methods

WLWH were recruited at their regular outpatient clinic visits, at the major Departments of Infectious Diseases in Denmark and Finland, from January 2012 to October 2013. A questionnaire was developed, study participants were informed of the nature of study and, if they agreed to participate and signed a consent form, they filled in the questionnaire. Demographic information on the participants was obtained from patient files (in Finland) or from a national HIV cohort (in Denmark). Statistical analysis was performed using STATA^®, version 11.

Results

In total, 560 women were included in the study. The median age was 44 years. The majority were of white European origin, with fully suppressed HIV viral load, CD4 cell count >350 µL and mild or no symptoms of their HIV infection. A total of 62% were sexually active, stating condom use as their sole form of contraception. Of the sexually inactive women, one-third were in steady relationships. Eighty percent reported prior pregnancies, of which the majority had one or more children. Most children were born prior to the women''s HIV diagnosis and the mode of conception was predominantly natural. One-quarter of the participating women desired pregnancy, while more than half did not. The remaining quarter either stated that they already had the desired number of children or chose not to answer the question. Fourteen percent stated that their HIV diagnosis ended their wish for children; of these women, the median time of diagnosis was between 1995 and 1996. Pregnancy had been attempted unsuccessfully in one-quarter of study participants. The final question inquired what the risk of mother-to-child transmission was, with all precautions taken. Fifteen percent estimated the risk to be above two percent.

Conclusions

In conclusion, the majority of WLWH in industrialized settings in Denmark and Finland have few HIV-related symptoms, are sexually active and have a strong desire for children.     

Hypothalamic-Pituitary and Thyroid Function in Chronic Alcoholics with Neurological Complications

Endocrinological tests were performed in 14 chronic alcoholic men with signs of intellectual impairment and/or peripheral neuropathy. All had been abstinent from alcohol for at least 1 month. Basal serum growth hormone (GH) was consistently increased in only one patient whereas the GH responses to insulin hypoglycemia stimulation was normal in all patients. Thyroid function values (T4, T3, rT3, TSH) were normal in all patients whereas baseline serum prolactin values were significantly increased in alcoholics as compared with a control group. In a combined TRH- and GnRH-stimulation tests, GH-responses were also normal whereas TSH and prolactin responses were blunted or absent in about half of the patients, the responses correlating significantly (p less than 0.01). It is concluded that disturbances in the hypothalamic-pituitary axis may occur in chronic alcoholics with nervous impairment independently of the physical deterioration, which often is associated with chronic alcoholism.     

Cripto‐1 Expression in Glioblastoma Multiforme

Human glioblastoma multiforme (GBM) is an aggressive cancer with a very poor prognosis. Cripto‐1 (CR‐1) has a key regulatory role in embryogenesis, while in adult tissue re‐expression of CR‐1 has been correlated to malignant progression in solid cancers of non‐neuronal origin. As CR‐1 expression has yet to be described in cerebral cancer and CR‐1 is regulated by signaling pathways dysregulated in GBM, we aimed to investigate CR‐1 in the context of expression in GBM. The study was performed using enzyme‐linked immunosorbent assay (ELISA), Western blotting, polymerase chain reaction (PCR) and immunohistochemistry to analyze the blood and tissue from 28 GBM and 4 low‐grade glioma patients. Within the patient cohort, we found high CR‐1 protein levels in blood plasma to significantly correlate with a shorter overall survival. We identified CR‐1 in different areas of GBM tissue, including perivascular tumor cells, and in endothelial cells. Collectively, our data suggest that CR‐1 could be a prognostic biomarker for GBM with the potential of being a therapeutic target.     

Influence of Carrier Gas Composition on the Stress of Al2O3 Coatings Prepared by the Aerosol Deposition Method

Al₂O₃ films were prepared by the aerosol deposition method at room temperature using different carrier gas compositions. The layers were deposited on alumina substrates and the film stress of the layer was calculated by measuring the deformation of the substrate. It was shown that the film stress can be halved by using oxygen instead of nitrogen or helium as the carrier gas. The substrates were annealed at different temperature steps to gain information about the temperature dependence of the reduction of the implemented stress. Total relaxation of the stress can already be achieved at 300 °C. The XRD pattern shows crystallite growth and reduction of microstrain while annealing.     

Impact of gender on the risk of AIDS-defining illnesses and mortality in Danish HIV-1-infected patients: A nationwide cohort study

Abstract Background: Gender differences in the risk of AIDS-defining illness (ADI) and mortality have been reported in the HIV-1-infected (HIV-positive) population, with conflicting findings. We aimed to assess the impact of gender on the risk of ADI and death in HIV-positive patients infected sexually. Methods: This was a population-based, nationwide cohort study of incident Danish HIV-positive individuals infected by sexual contact. Outcomes were progression to AIDS and death. We used Cox proportional hazards models and Poisson regression analyses to calculate the risk of progression to AIDS and mortality rate ratios (MRR) between risk groups and compared these with the general Danish population. Results: We identified 587 heterosexually infected women, 583 men who have sex with women (MSW), and 1089 men who have sex with men (MSM). The total follow-up time was 13,708 person-y. At the time of HIV diagnosis MSM had a lower prevalence of AIDS compared to MSW. Women and MSW presented more often with tuberculosis and less often with AIDS-defining cancers compared to MSM. In the adjusted analyses we observed no differences in progression to AIDS. In the adjusted analyses of risk of death, there were no differences between the 3 risk groups, although we saw a trend towards a higher risk of death in older MSW. MSM had a lower risk of death compared to the background population than women and MSW. Conclusions: In the Danish HIV population, gender has no major impact on progression to AIDS or mortality. Differences in these factors between women, MSW, and MSM are mainly due to confounding from race and CD4 + cell count at diagnosis.     

The 5‐HT4 receptor levels in hippocampus correlates inversely with memory test performance in humans

The cerebral serotonin (5‐HT) system is involved in cognitive functions such as memory and learning and animal studies have repeatedly shown that stimulation of the 5‐HT type 4 receptor (5‐HT₄R) facilitates memory and learning and further that the 5‐HT₄R modulates cellular memory processes in hippocampus. However, any associations between memory functions and the expression of the 5‐HT₄R in the human hippocampus have not been investigated. Using positron emission tomography with the tracer [¹¹C]SB207145 and Reys Auditory Verbal Learning Test we aimed to examine the individual variation of the 5‐HT4R binding in hippocampus in relation to memory acquisition and consolidation in healthy young volunteers. We found significant, negative associations between the immediate recall scores and left and right hippocampal BP_ND, (p = 0.009 and p = 0.010 respectively) and between the right hippocampal BP_ND and delayed recall (p = 0.014). These findings provide evidence that the 5‐HT₄R is associated with memory functions in the human hippocampus and potentially pharmacological stimulation of the receptor may improve episodic memory.
