Camille Webb, Miguel M Cabada
PURPOSE OF REVIEW: Cestodes infections in humans are among the most prevalent parasitosis worldwide. Although tapeworm infection is often asymptomatic, they can be associated with a range of symptoms. The landscape of cestode infections is changing with rapid diagnosis techniques and advanced molecular diagnosis aiding in identification of species specific epidemiology. RECENT FINDINGS: Traditional descriptions of species by location have been challenged with molecular diagnostic techniques, which show variation in distribution of species, thought to be because of globalization and importation of disease...

Kirsten E Lyke
PURPOSE OF REVIEW: Great progress has been made in reducing malaria morbidity and mortality, yet the parasite continues to cause a startling 200 million infections and 500 000 deaths annually. Malaria vaccine development is pushing new boundaries by steady advancement toward a licensed product. RECENT FINDINGS: Despite 50 years of research, the complexity of Plasmoidum falciparum confounds all attempts to eradicate the organism. This very complexity has pushed the boundaries of vaccine development to new heights, yet it remains to be seen if an affordable vaccine can provide durable and high-level protection...

#6
Claudio Alba, Ana Blanco, Teresa Alarcón
PURPOSE OF REVIEW: Treatment of Helicobacter pylori is difficult nowadays because of its high resistance. The prevalence and mechanism of resistance, the different methods to detect it and the clinical implication of resistance were addressed in several research papers last year. RECENT FINDINGS: Clarithromycin-resistant H. pylori has been recognized by the WHO as 'high priority', for which new antibiotics are needed. Moreover, the Maastricht consensus recommended, in areas with high resistance, that susceptibility tests should be performed, at least after a treatment failure...

Kristjana H Ásbjörnsdóttir, Arianna R Means, Marleen Werkman, Judd L Walson
PURPOSE OF REVIEW: Soil-transmitted helminths (STH) are endemic in 120 countries and are associated with substantial morbidity and loss of economic productivity. Although current WHO guidelines focus on morbidity control through mass drug administration (MDA), there is global interest in whether a strategy targeting disease elimination might be feasible in some settings. This review summarizes the prospects for switching from control to an elimination strategy. RECENT FINDINGS: STH control efforts have reduced the intensity of infections in targeted populations with associated reductions in morbidity...

Rania Assab, Narimane Nekkab, Pascal Crépey, Pascal Astagneau, Didier Guillemot, Lulla Opatowski, Laura Temime
PURPOSE OF REVIEW: Mathematical modeling approaches have brought important contributions to the study of pathogen spread in healthcare settings over the last 20 years. Here, we conduct a comprehensive systematic review of mathematical models of disease transmission in healthcare settings and assess the application of contact and patient transfer network data over time and their impact on our understanding of transmission dynamics of infections. RECENT FINDINGS: Recently, with the increasing availability of data on the structure of interindividual and interinstitution networks, models incorporating this type of information have been proposed, with the aim of providing more realistic predictions of disease transmission in healthcare settings...

Julia Johnson, Caroline Quach
PURPOSE OF REVIEW: Neonates in the neonatal ICU (NICU) are uniquely vulnerable to colonization and infection with pathogens such as multidrug resistant Gram-negative bacteria, which in turn are associated with increased infection-related morbidities and higher case-fatality rates. We reviewed the English, French, and German language literature published between 2015 and 2017, for reports of NICU outbreaks. RECENT FINDINGS: A total of 39 outbreaks in NICUs were reported with Gram-negative bacteria (n = 21; 54%) causing most, and extended spectrum beta-lactamase-producing organisms being the most frequent resistance mechanism reported (n = 5)...

Elizabeth Robilotti, Marisa Holubar, Susan K Seo, Stan Deresinski
PURPOSE OF REVIEW: Antimicrobial stewardship is the primary intervention in the battle against antimicrobial resistance, but clinicians do not always apply many key antimicrobial stewardship principles to patients with significant immune defects due to lack of data and fear of bad outcomes. We review evidence regarding the application of stewardship principles to immunocompromised patients, with a focus on solid organ and hematopoietic stem cell transplant recipients. RECENT FINDINGS: Antimicrobial stewardship programs (ASPs), targeting immunocompromised patient populations such as oncology and transplant, are gaining traction...
