Partners with Mixed HIV Status
Partners With Mixed HIV Status SERODISCORDANT RELATIONSHIPS Relationships in which one or more people has HIV and one or more people do not have HIV are sometimes called serodiscordant or mixed serostatus. The term serodiscordant is made up of two roots: 1. Sero—meaning blood 2. Discordant—meaning different or non-matching HIV isn’t the first topic that comes up when most people start dating. You may not know the HIV status of your partner(s). You might not even have been tested yourself. It can be very difficult to talk about HIV status. WHAT ARE THE SPECIAL ISSUES FOR SERODISCORDANT RELATIONSHIPS? People in mixed HIV status relationships face all the same things as other people in relationship. But there are some extra issues: The partner(s) with HIV might focus on not infecting their partner(s). The partner(s) who do not have HIV may concentrate on taking care of the person/people with HIV. This can cause a serious lack of balance in the relationship. HIV can cause changes in the body. Antiretroviral medications (ARVs) may have unpleasant side effects. This might give the partner(s) with HIV negative feelings about their body and their health. It may be difficult to feel attractive and have a normal romantic relationship. Fear of transmitting HIV can cause an excess of caution. This might even stop all sexual activity.

Reticulate Evolution Everywhere
Reticulate Evolution Everywhere Nathalie Gontier Abstract Reticulation is a recurring evolutionary pattern found in phylogenetic reconstructions of life. The pattern results from how species interact and evolve by mechanisms and processes including symbiosis; symbiogenesis; lateral gene transfer (that occurs via bacterial conjugation, transformation, transduction, Gene Transfer Agents, or the movements of transposons, retrotransposons, and other mobile genetic elements); hybridization or divergence with gene flow; and infec- tious heredity (induced either directly by bacteria, bacteriophages, viruses, pri- ons, protozoa and fungi, or via vectors that transmit these pathogens). Research on reticulate evolution today takes on inter- and transdisciplinary proportions and is able to unite distinct research fields ranging from microbiology and molecular genetics to evolutionary biology and the biomedical sciences. This chapter sum- marizes the main principles of the diverse reticulate evolutionary mechanisms and situates them into the chapters that make up this volume. Keywords Reticulate evolution · Symbiosis · Symbiogenesis · Lateral Gene Transfer · Infectious agents · Microbiome · Viriome · Virolution · Hybridization · Divergence with gene flow · Evolutionary patterns · Extended Synthesis 1 Reticulate Evolution: Patterns, Processes, Mechanisms According to the Online Etymology Dictionary (http://www.etymonline.com), the word reticulate is an adjective that stems from the Latin words “re¯ticulātus” (having a net-like pattern) and re¯ticulum (little net). When scholars identify the evolution of life as being “reticulated,” they first and foremost refer to a recurring evolutionary pattern. N.

Santelli, MD, MPH† *University of Wisconsin, Madison, WI, USA; †Columbia University, New York, NY, USA; ‡Rakai Health Sciences Program, Kalisizo, Rakai District, Uganda DOI: 10.1111/jsm.12375 ABSTRACT Introduction. Although understudied in the context of AIDS, use of withdrawal (coitus interruptus) with or in place of other prevention methods affects exposure to both pregnancy and human immunodeficiency virus (HIV). Aim. We used mixed methods to assess use of withdrawal among 15–24-year-olds in a rural Ugandan setting with considerable HIV prevalence. Methods. We measured withdrawal reporting among (i) sexually active 15–24-year-olds enrolled in a quantitative community survey (n = 6,722) and (ii) in-depth qualitative interview participants systematically selected from the latest round of the community survey (N = 60). Respondents were asked about family planning and HIV prevention practices, including a direct question about withdrawal in the in-depth interviews. Main Outcome Measures. The main outcome measures were reports of current use of withdrawal on the quanti- tative survey (general question about family planning methods) and reports of current or recent use withdrawal in qualitative interviews (specific question about withdrawal). Qualitative interviews also probed for factors associated with withdrawal use. Results. Although less than 1% of quantitative survey participants spontaneously named withdrawal as their current family planning method, 48% of qualitative interview respondents reported current or lifetime use of withdrawal. -

The care of HIV-infected women is not simple and must be focused on including the current and future health of these women, the minimization of the risk of maternal–infant transmission and the maintenance of the well-being of the fetus and neonate. Many maternal and obstetrical factors can affect the vertical transmission. The answer to this problem is the optimal medical and obstetrical care. Keywords: Pregnancy; HIV; Vertical transmission of the correlation between its presence and the immunsupression [12,13]. There are many pathological connections which can clear Introduction out this correlation. To begin with, we must give a great attention to The human immunodeficiency virus continues to be expanded the compromised immune status and general poor health of HIV- around the world causing an estimated 16,000 new infections per day infected women which allow them to become more vulnerable to [1]. 2.1 million women and 590,000 children below age of 15 were infections and mostly to puerperal sepsis [14].

FAQ113 -- HIV and Pregnancy
AQ The American College of Obstetricians and Gynecologists FREQUENTLY ASKED QUESTIONS FAQ113 fPREGNANCY HIV and Pregnancy • What is human immunodeficiency virus (HIV)? • How do you get HIV? • How do you get AIDS? • How long does it take for HIV to develop into AIDS? • Can HIV be treated? • If I am infected with HIV and pregnant, can I pass HIV to my baby? • What can I do to reduce the risk of passing HIV on to my baby? • Why is HIV treatment recommended during pregnancy? • Are there any side effects of HIV drugs? • What is my viral load? • Why is it important for my viral load and CD4 cell count to be monitored? • Should I still use condoms during sex even though I am pregnant? • Are there extra risks for me if I am HIV positive and I have a cesarean delivery? • After I give birth, how will I know if my baby is infected with HIV? • Glossary What is human immunodeficiency virus (HIV)? Human immunodeficiency virus (HIV) is the virus that causes acquired immunodeficiency syndrome (AIDS). How do you get HIV? HIV enters the bloodstream by way of body fluids, such as blood or semen. Once in the blood, the virus invades and kills CD4 cells. CD4 cells are key cells of the immune system. When these cells are destroyed, the body is less able to fight disease. How do you get AIDS? AIDS occurs when the number of CD4 cells decreases below a certain level and the person gets sick with diseases that the immune system would normally fight off. -
