There is a growing discourse worldwide on the impact of the Human Immunodeficiency Virus (HIV) on "at risk youths". In response, five HIV-positive Nigerian adolescent girls were qualitatively investigated in collaboration with a non-governmental organisation (NGO) in Ibadan, an urban settlement in Nigeria in 2013. Using a secondary data analysis from a photo voice component of the research, combined with narratives, we show that participants possess the capacity to overcome their adversities from the effects of HIV infection and remain resilient...

OBJECTIVE: The retention of patients on antiretroviral therapy (ART) is key to achieving global targets in response to the HIV epidemic. Loss to follow-up (LTFU) can be substantial, with unknown outcomes for patients lost to ART programs. We examined changes in outcomes of patients LTFU over calendar time, assessed associations with other studies and program characteristics, and investigated the relative success of different tracing methods. METHODS: We performed a systematic review and logistic random-effects meta-regression analysis of studies that traced adults or children who started ART and were LTFU in sub-Saharan African treatment programs...

Surgical intervention for severe tricuspid regurgitation secondary to remote infective endocarditis has been infrequent, especially in patients also infected with the human immunodeficiency virus (HIV). We describe the case of a 62-year-old HIV-positive man, with a 24-year history of endocarditis caused by intravenous heroin use, who presented with severe tricuspid regurgitation. The patient was initially asymptomatic, was taking antiretroviral medications, and had a satisfactory CD4 count and an undetectable viral load, so we decided to manage the regurgitation conservatively...

BACKGROUND Pulmonary infections are a major cause of mortality and morbidity in patients infected with human immunodeficiency virus (HIV) and can progress rapidly to respiratory failure and death without appropriate therapy. Herein, we present a rare case of an advanced HIV infection and Rhodoccocus equi (R. equi) pneumonia in a young male who had severe paradoxical immune reconstitution inflammatory syndrome (IRIS). CASE REPORT A 47-year-old nonsmoking Hispanic man with advanced HIV infection presented with severe acute necrotizing pneumonia secondary to R...

Toxoplasmic encephalitis (TE) is caused by Toxoplasma gondii infection and can be a life-threatening disease in immunocompromised patients. This study evaluated the rate of relapse associated with pyrimethamine-based maintenance therapy (i.e. secondary prophylaxis) in patients with human immunodeficiency virus (HIV) or AIDs treated prior to and after the common use (i.e. 1996) of highly active antiretroviral therapy (HAART) (pre-HAART and post-HAART, respectively). PubMed, Google Scholar, and Cochrane databases were searched to 6 June 2016 using search terms: pyrimethamine, Daraprim, Fansidar, Metakelfin, Fansimef, 5-(4-chlorophenyl)-6-ethyl-2,4-pyrimidinediamine, encephalitis, cerebral, toxoplasmosis, toxoplasmic, and gondii...

Zearalenone (ZEA) is an estrogenic mycotoxin mainly produced as a secondary metabolite by numerous species of Fusarium. Previous work showed that ZEA had a negative impact on domestic animals with regard to reproduction. The adverse effects and the mechanisms of ZEA on mammalian ovarian folliculogenesis remain largely unknown, particularly its effect on primordial follicle formation. Thus, we investigated the biological effects of ZEA exposure on murine ovarian germ cell cyst breakdown and primordial follicle assembly...

Lipoprotein (a) [Lp(a)] is an independent but moderate, predictor for coronary heart disease (CHD) prevalence and severity. Several established and emerging cardiovascular (CV) risk factors including age, gender, ethnicity, smoking, dyslipidemia, hypertension, obesity, type 2 diabetes mellitus, alcohol consumption, arterial stiffness and hyperuricemia have been linked to Lp(a) metabolism. Apart from CHD, Lp(a) has been also associated with non-cardiac vascular diseases and diseases associated with increased CV risk such as chronic kidney disease, metabolic syndrome, non-alcoholic fatty liver disease, erectile dysfunction, obstructive sleep apnea syndrome, inflammatory bowel diseases and human immunodeficiency virus infection...

BACKGROUND: Microcephaly has become a major public health problem in Brazil. The total number of newborns with microcephaly was reported to be >4000 in June 2016. Studies suggest that Zika Virus is a major cause of new microcephaly cases in Brazil. Inside the uterus, the foetus is surrounded by the Amniotic Fluid, a proximal fluid that contains foetal and maternal cells as well as microorganisms and where Zika Virus was already found. CASE PRESENTATION: A previous study reported the presence of the Zika Virus in the amniotic fluid (collected in the 28th gestational week) of two pregnant women carrying microcephaly foetuses in Brazil...

Intravenous immunoglobulin (IVIg) is accepted as an effective and well-tolerated treatment for primary and secondary immunodeficiencies (ID) and immune thrombocytopenia (ITP). Adverse reactions of IVIg are usually mild, comprising transient flu-like symptoms, change in blood pressure and tachycardia. However IVIg therapy can be burdensome for both patients and healthcare facilities, since the infusion may take up to 4h to administer. The objective of our multicentre, prospective, open-label phase III trial was to evaluate the tolerability and safety of human normal immunoglobulin 50g/l (Ig VENA) at high intravenous infusion rates in adult patients with ID and ITP who had previously tolerated IVIg treatment, by progressively increasing infusion rate up to 8ml/kg/hr...

BACKGROUND: As adolescents transition from childhood to adulthood, effective mother-daughter communication on sexuality plays a role in reducing high-risk behaviours linked to human immunodeficiency virus (HIV) infection and early pregnancy and childbirth. The objective of the study was to examine the prevalence of mother-daughter communication on sexuality and associated factors in Sagamu, southwest Nigeria. METHODS: Using multistage sampling, surveys were conducted using 234 female youth enrolled at a secondary school...

Although Hodgkin lymphoma (HL) is curable with current therapy, at least 20% of patients relapse or fail to make complete remission. In addition, patients who achieve long-term disease-free survival frequently undergo infertility, secondary malignancies, and cardiac failure, which are related to chemotherapeutic agents and radiation therapies. Hence, new therapeutic strategies able to counteract the HL disease in this important patient population are still a matter of study. Estrogens, in particular 17β-estradiol (E2), have been suggested to play a role in lymphoma cell homeostasis by estrogen receptors (ER) β activation...

BACKGROUND: Human Immunodeficiency Virus (HIV) pandemic has exacerbated tuberculosis disease especially in Sub-Saharan African countries. The World Health Organization (WHO) and Joint United Nations Program on HIV/AIDS (UNAIDS) have recommended Isoniazid Preventive Therapy (IPT) for HIV infected patients to reduce the burden of tuberculosis (TB). Ethiopia has been implementing IPT since 2007. However, effectiveness of IPT in averting occurrence of active tuberculosis among HIV infected patients has not been assessed...

BACKGROUND: Early substance use threatens many American Indian/Alaska Native (AI/AN) communities, as it is a risk factor for maladaptive use and adverse health outcomes. Marijuana is among the first substances used by AI/AN youth, and its use becomes widespread during adolescence. Interventions that delay or reduce marijuana use hold the promise of curbing substance disorders and other health risk disparities in AI/AN populations. OBJECTIVES: We evaluated the effectiveness of the Circle of Life (COL) program in reducing marijuana use among young AI adolescents...

Current research states that AIDS pathogenesis has its roots in a chronic activation of immune system secondary to human immunodeficiency virus (HIV)-induced proliferation of T cells, B cells, NK cells, and macrophages. Immune activation due to acute HIV infection can be highly detrimental to allograft survival in a renal transplant recipient. In this report, we describe a 32-year-old African-American male patient who underwent a second live donor renal transplant, following which he developed acute allograft rejection coincident with newly acquired HIV seropositivity...

BACKGROUND: Splenic abscesses are rare entities; reports are commonly described in immunocompromised patients (72%) as: hematologic diseases, diabetes, endocarditis, acquired immunodeficiency syndrome, transplant patients and subjects who had abdominal trauma or splenic infarction. The main and most serious complication is the abscess rupture into the peritoneal cavity or adjacent organs (stomach or colon), which determines hemodynamic instability or septic state. CLINICAL CASE: Fifty-year-old man, who was admitted at Emergency Room due eight days' progressive, oppressive, and current pain; intensity 4/10, irradiated at hemi-back, which was higher intensity during the standing and decreased at supine position...

Tenofovir disoproxil fumarate (TDF) is one of the most widely used treatment options for human immunodeficiency virus (HIV) and HBV infections. Despite its efficacy and safety, some cases of nephrotoxicity have been reported in the treatment of HIV patients. Even more recently, very few cases of Fanconi syndrome associated with tenofovir therapy in HBV monoinfection have been reported. Herein, we report a case of a 47-year-old male with an HBV monoinfection, who developed Fanconi syndrome and a secondary osteomalacia with multiple bone pain...

Tyrosine kinase inhibitor (TKI) treatment of chronic myeloid leukemia (CML) has limited efficacy against leukemia stem cells (LSC) responsible for disease propagation, and most CML patients require continued TKI treatment to maintain remission. LSC maintenance is related, at least in part, to signals from the bone marrow microenvironment (BMM). Our previous studies have shown that Wnt signaling from the BMM contributes to preservation of CML LSC following TKI treatment. Secretion of Wnt ligands requires their modification by the O-acyl transferase Porcupine (PORCN)...

REVIEW
Sarah C Keane, Michael F Summers
The 5'-leader of the human immunodeficiency virus type 1 (HIV-1) genome plays several critical roles during viral replication, including differentially establishing mRNA versus genomic RNA (gRNA) fates. As observed for proteins, the function of the RNA is tightly regulated by its structure, and a common paradigm has been that genome function is temporally modulated by structural changes in the 5'-leader. Over the past 30 years, combinations of nucleotide reactivity mapping experiments with biochemistry, mutagenesis, and phylogenetic studies have provided clues regarding the secondary structures of stretches of residues within the leader that adopt functionally discrete domains...
