Alterations in Host Lipid Metabolism Produced During Visceral Leishmaniasis Infections
This article aims to review lipid metabolism of both parasite and host, and how the former affects the latter.Recent FindingsLeishmania uses the host ’s cholesterol to ensure macrophage phagocytosis and evade immune response. Additionally, the host’s lipid bodies have key roles in disease progression and development of the parasite inside the cell. This induces changes in the patient’s serum lipid profile like hypertriglyceridemia and low H DL levels.SummaryChanges in the lipid profile and metabolism in both parasite and host during development of the disease depend on the presence of lipid bodies.

Hepatitis E in Pregnant Women and the Potential Use of HEV Vaccine to Prevent Maternal Infection and Mortality
This article reviews the latest knowledge on HEV in pregnancy, the vaccine candidates that have reached clinical trials, and their potential use during pregnancy.Recent FindingsNew evidence suggests that a genotype-specific tropism to uteroplacental cells contributes to the multifactorial pathology leading to the increased severity of HEV during pregnancy. Data from pregnant women inadvertently vaccinated are limited but show similar rates of adverse events as non-pregnant women, and no evident harm to newborns. Protective anti-HEV IgG antibodies are estimated to last longer after vaccination than natural infection. Accele...

Pregnant Women, Vaccine Development for Emerging and Epidemic Viral Infections and Maternal Immunization: Human Rights and the Global Survival of Mothers and Infants
This article analyzes current issues related to maternal vaccination with a focus on emerging and epidemic viral infections and human rights.Recent FindingsHistorically, pregnant women have not been considered in the development of vaccines and have been excluded from participating in clinical trials and vaccination campaigns. Because of risk for injury and death of mothers and fetuses/infants during infectious disease outbreaks, it is important to consider their rights to receive any potential form of prevention or therapy available to non-pregnant individuals in order to enhance their well-being.SummaryIt is unacceptable...

Current Perspectives on Maternal Influenza Immunization
AbstractPurpose of ReviewPregnant women and young infants are more likely to experience severe complications associated with influenza infection and are at increased risk of hospitalization. Influenza vaccination during pregnancy produces antibodies which protect the mother against infection, and due to transplacental transfer of maternal antibodies before birth, it also protects the infant in the first few months of life.Recent FindingsIn many countries, influenza vaccination is recommended during pregnancy to protect mothers and their infants. In fact, influenza vaccine is the most widely used vaccine in pregnancy global...

Is the Diet Industry Disrupting Your Microbiota?
AbstractPurpose of ReviewGut microbes are essential to human health and dietary patterns can influence bacterial diversity and abundance, resulting in either health or disease. Here, we review if high-fat diets motivated by the diet industry can result in disruption of microbiota, which in turn leads to disease.Recent FindingsA high-fat diet induces microbiota dysbiosis, which is related to obesity and chronic diseases. Some mechanisms include higher bile acid secretion, which conduct its detergent effect on bacterial cell membranes, inducing the loss of non-bile-resistant species.

When Is It Acceptable to Vaccinate Pregnant Women? Risk, Ethics, and Politics of Governance in Epidemic Crises
AbstractPurpose of ReviewIn some countries, pregnant women experience disproportionately high morbidity and mortality during infectious disease outbreaks due to a variety of gender-based factors and pregnancy-related immunological changes. Despite this, the interests of pregnant women have largely been absent from policies that guide the design of clinical trials and the deployment of vaccines in epidemic contexts. This review examines historic precedent for both excluding and including pregnant women in vaccine trials and considers the rights of pregnant women in epidemic crises.Recent FindingsThe latest research reveals ...

Exploiting Lipids to Develop Anticryptococcal Vaccines
AbstractPurpose of ReviewCryptococcus spp. are responsible for life-threatening infections in humans causing mortality rates of 70% in developing countries. Antifungal therapy to combat cryptococcosis is based on the combination of amphotericin B, azoles, and 5-flucytosine. However, treatment failure is frequently triggered by antifungal resistance, drug-drug interactions, and toxicity. New alternatives to prevent cryptococcosis are imperative. Here, we discuss the roles of lipids in the immunological control of the disease caused byCryptococcus spp.Recent FindingsRecently, remarkable advances on immunology of fungal infec...

AbstractPurpose of ReviewPervasive fungal infection among the immunocompromised population, in conjunction with a lack of effective treatment options, has demanded further scrutiny. Millions of people are still dying annually from fungal infections. While existing treatment for these fungal infections exists, it is difficult to administer without adverse effects in the immunocompromised and is slowly becoming obsolete due to varying mutation rates and rising resistance in multiple species. Thus, vaccines may be a viable target for preventing and treating fungal infections and addressing the critical challenge of such infec...
