REVIEW
Shelli Farhadian, Payal Patel, Serena Spudich
PURPOSE OF REVIEW: HIV-associated neurocognitive disorders (HAND) are common in patients with HIV disease, even during suppressive combination antiretroviral therapy (cART). This review article addresses the pathogenesis of HAND, focusing on important findings from the last 5 years. RECENT FINDINGS: While HIV-associated dementia is now rare in settings with cART availability, mild forms of HAND are increasing in prevalence. Biomarkers of cellular injury, such as neurofilament light chain and neopterin, can detect early stages of neuroinflammation associated with HIV infection and are increased even in asymptomatic individuals with chronic HIV infection...

REVIEW
Jason A Clayton, Philip Toltzis
PURPOSE OF REVIEW: We focus on two recent aspects of Clostridium difficile infection (CDI) in children, namely the emergence of community-associated CDI (CA-CDI) and the incidence and prevention of recurrent CDI. RECENT FINDINGS: Current surveys suggest that a large proportion of all pediatric CDI is acquired in the community. Risk factors and frequency estimates of pediatric CA-CDI, however, are confounded in babies and toddlers by a high rate of asymptomatic excretion, whose detection likely is exaggerated by the wide use of highly sensitive nucleic acid amplification tests...

#3
REVIEW
David P Calfee
Since the first clinical isolate of methicillin-resistant Staphylococcus aureus was described in 1961, this pathogen has established itself as a leading cause of health care-associated infections. More recently, MRSA has become a relatively common cause of infection among persons without typical health care-associated risk factors and is now the most common cause of community-onset purulent skin and soft-tissue infections in many regions of the USA. The appearance of "community-associated" MRSA is not due to the expansion of health care-associated MRSA into the community but rather the result of the independent emergence of a novel clone of MRSA...

REVIEW
Michael W Stewart
PURPOSE OF REVIEW: Ophthalmologic conditions were among the earliest described findings in patients with the acquired immunodeficiency syndrome (AIDS). The purpose of this review is to highlight recent changes in the pathophysiology and management of ophthalmologic conditions in patients infected with the human immunodeficiency virus (HIV). RECENT FINDINGS: The introduction of highly active antiretroviral therapy (HAART) in 1996 changed ophthalmologic findings from predominantly acute infectious diseases to chronic, slowly progressive, debilitating conditions...

REVIEW
Rose M Kohinke, Amy L Pakyz
PURPOSE OF REVIEW: Vancomycin-resistant Enterococci (VRE) infections are problematic due to limited availability of anti-VRE agents and their potential for adverse effects and drug interactions. This review focuses on the role of daptomycin in treating VRE infections by summarizing key points of relevant clinical studies. RECENT FINDINGS: Higher doses of daptomycin (≥ 6 mg/kg), as compared to standard doses, were found to be safe in terms of creatinine phosphokinase elevation and associated with successful infection outcomes and microbiological clearance...

REVIEW
S T van Dijk, S J Rottier, A A W van Geloven, M A Boermeester
PURPOSE OF REVIEW: Since the treatment of acute diverticulitis has become more conservative over the last years, knowledge of conservative treatment strategies is increasingly important. RECENT FINDINGS: Several treatment strategies that previously have been imposed as routine treatment are now obsolete. Uncomplicated diverticulitis patients can be treated without antibiotics, without bed rest, and without dietary restrictions; and a selected group of patients can be treated as outpatients...

#9
REVIEW
Sylvain A Lother, Natasha Press
PURPOSE OF THE REVIEW: Methicillin-sensitive Staphylococcus aureus (MSSA) bacteremia is a common cause of morbidity and mortality. First-line treatment requires frequent daily doses of an anti-staphylococcal beta-lactam. However, some physicians prescribe simpler once-daily regimens to improve compliance and improve healthcare utilization. We reviewed the literature regarding advantages, pitfalls, and efficacy of once-daily treatment options for MSSA bacteremia. RECENT FINDINGS: Several once-daily antibiotics are effective in vitro against MSSA (ceftriaxone, daptomycin, telavancin, dalbavancin, oritavancin, tedizolid, ertapenem, fluoroquinolones, and others), but there is insufficient evidence to support these agents for MSSA bacteremia...

REVIEW
Pavithra Srinivas, Kaitlyn Rivard
PURPOSE OF REVIEW: The polymyxins are one of the last line antimicrobial classes to retain activity against multidrug-resistant Gram-negative bacilli. However, with the increased use of polymyxins in recent years, reports of resistance have also been increasing. We aimed to describe the mechanisms and occurrence of polymyxin resistance in Gram-negative organisms and propose strategies to overcome resistance. RECENT FINDINGS: The most common mechanism of acquired resistance to the polymyxins is via modification of the bacterial outer membrane lipopolysaccharide...

REVIEW
Aurélia Henn, Clara Flateau, Sébastien Gallien
PURPOSE OF REVIEW: The purpose of this review was to provide current data on clinical presentation, diagnosis, and treatment of primary HIV infection (PHI). RECENT FINDINGS: In 65 to 95% of cases, PHI causes acute retroviral syndrome presenting with unspecific flu-like symptoms. Symptomatic PHI was associated with a faster clinical and immunological progression of HIV infection. Point-of-care tests remain less sensitive than fourth-generation immunoassays (IA) in PHI, especially after tenofovir-based prophylaxis use...

REVIEW
James Grogan, Karen Roos
PURPOSE OF REVIEW: This review explores the history of serogroup B meningitis outbreaks in American universities and the rise of the monovalent serogroup B meningococcus vaccines (MenB). RECENT FINDINGS: Serogroup B meningitis represents 30% of American meningococcal infections and had no commercially available vaccine in the USA until 2013 when the FDA made an expanded allowance for importation of the MenB-4C vaccine for outbreaks at two American universities. Infections of Neisseria meningitidis, notably meningococcal meningitis represent a continued, lethal threat to the pediatric and adolescent populations and those with primary or acquired complement component deficiencies, largely mitigated by the quadrivalent meningococcal conjugated vaccine against serogroups A, C, W, and Y (MenACWY)...

REVIEW
Braden Millan, Michael Laffin, Karen Madsen
PURPOSE OF REVIEW: Fecal microbiota transplantation (FMT) has been established as standard of care in the treatment of antibiotic refractory Clostridium difficile infection (RCDI). This review examines the current evidence that exists to support the use of FMT in the treatment of human disease beyond C. difficile infection. RECENT FINDINGS: Beneficial effects of FMT have been described in case series or small prospective trials on a wide spectrum of conditions, including inflammatory bowel disease, functional gastrointestinal disorders, non-alcoholic steatohepatitis, alcoholic hepatitis, hepatic encephalopathy, and neuropsychiatric conditions, and in limiting antibiotic-resistant bacterial infections...

REVIEW
Westyn Branch-Elliman
PURPOSE OF REVIEW: Cardiovascular implantable electronic device (CIED) infections are highly morbid, common, and costly, and rates are increasing (Sohail et al. Arch Intern Med 171(20):1821-8 2011; Voigt et al. J Am Coll Cardiol 48(3):590-1 2006). Factors that contribute to the development of CIED infections include patient factors (comorbid conditions, self-care, microbiome), procedural details (repeat procedure, contamination during procedure, appropriate pre-procedural prep, and antimicrobial use), environmental and organizational factors (patient safety culture, facility barriers, such as lack of space to store essential supplies, quality of environmental cleaning), and microbial factors (type of organism, virulence of organism)...
