    Tue, 19 Nov 2019
    Health authorities in Pakistan are responding to an ongoing outbreak of dengue fever. This outbreak was first reported on 8 July 2019 by the Khyber Teaching Hospital in Peshawar, Khyber Pakhtunkhwa (KP) province. Since then, three other provinces (Punjab, Balochistan, and Sindh), as well as Islamabad Capital Territory (ICT), and Azad Jammu and Kashmir (AJK; one of the two autonomous territories) have also reported cases of dengue fever.

    From 8 July to 12 November 2019, a total of 47,120 confirmed cases of dengue fever, including 75 deaths, were reported from the four provinces (KP, Punjab, Balochistan, and Sindh), Islamabad, and AJK.

    Thu, 14 Nov 2019
    On 10 October 2019, the National IHR Focal Point for Sudan notified WHO of 47 suspected cases of Rift Valley Fever (RVF), including two deaths in Arb’aat Area, Towashan Village, in El Qaneb locality, Red Sea State. The suspected cases presented with high-grade fever, headaches, joint pain, vomiting. There were no hemorrhagic signs or symptoms observed. The first case presented to the health facility on 19 September 2019.

    On 28 September 2019, a total of 14 samples were sent to the National Public Health Laboratory in Khartoum, and 5 tested positive for RVF by Immunoglobulin M (IgM) enzyme-linked immunosorbent assay (ELISA) and reverse-transcriptase polymerase chain reaction (RT-PCR). These samples were also tested for malaria and were found negative.

    Thu, 14 Nov 2019
    Six new confirmed cases were reported in the past week (6 to 12 November) in the ongoing Ebola virus disease (EVD) outbreak in North Kivu and Ituri provinces.

  • In Vitro Activity of Cefiderocol Against a Broad Range of Clinica...
    Wed, 13 Nov 2019
    Abstract
    Carbapenem-resistant gram-negative bacteria including Enterobacteriaceae as well as nonfermenters, such as Pseudomonas aeruginosa and Acinetobacter baumannii, have emerged as significant global clinical threats. Although new agents have recently been approved, none are active across the entire range of resistance mechanisms presented by carbapenem-resistant gram-negative bacteria. Cefiderocol, a novel siderophore cephalosporin, has been shown in large surveillance programs and independent in vitro studies to be highly active against all key gram-negative causative pathogens isolated from patients with hospital-acquired or ventilator-associated pneumonia, bloodstream infections, or complicated urinary tract infections. The improved structure, the novel mode of entry into bacteria, and its stability against carbapenemases enables cefiderocol to exhibit high potency against isolates that produce carbapenemases of all classes or are resistant due to porin channel mutations and/or efflux pump overexpression. Resistance to cefiderocol is uncommon and appears to be multifactorial.

  • Pathogen-focused Clinical Development to Address Unmet Medical Ne...
    Wed, 13 Nov 2019
    Abstract
    Historically, the regulatory requirements of the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for developing new antibiotics have not addressed pathogen-focused indications for drug approval. The design of the necessary randomized controlled trials traditionally involves the enrollment of patients with site-specific infections caused by susceptible as well as resistant pathogens. Cefiderocol has undergone a streamlined clinical development program to address serious carbapenem-resistant infections. The regulatory approach, and the pivotal clinical trials, differed between the FDA and EMA. In the United States, the APEKS-cUTI (Acinetobacter, Pseudomonas, Escherichia coli, Klebsiella, Stenotrophomonas–complicated urinary tract infection) study was conducted to provide the basis for FDA approval of a site-specific cUTI indication. The EMA, however, preferred the CREDIBLE-CR (A MultiCenter, RandomizED, Open-label ClInical Study of S-649266 or Best AvailabLE Therapy for the Treatment of Severe Infections Caused by Carbapenem-Resistant Gram-negative Pathogens) study, in which patients with nosocomial pneumonia, bloodstream infections, or cUTIs were enrolled if they had a carbapenem-resistant pathogen. The resulting European label will be pathogen focused rather than infection site specific (ie, treatment of gram-negative infection in patients with limited treatment options). The implications and limitations of these different regulatory processes are discussed.

  • Cefiderocol: Discovery, Chemistry, and In Vivo Profiles of a Nove...
    Wed, 13 Nov 2019
    Abstract
    The emergence of antimicrobial resistance is a significant public health issue worldwide, particularly for healthcare-associated infections caused by carbapenem-resistant gram-negative pathogens. Cefiderocol is a novel siderophore cephalosporin targeting gram-negative bacteria, including strains with carbapenem resistance. The structural characteristics of cefiderocol show similarity to both ceftazidime and cefepime, which enable cefiderocol to withstand hydrolysis by β-lactamases. The unique chemical component is the addition of a catechol moiety on the C-3 side chain, which chelates iron and mimics naturally occurring siderophore molecules. Following the chelation of iron, cefiderocol is actively transported across the outer membrane of the bacterial cell to the periplasmic space via specialized iron transporter channels. Furthermore, cefiderocol has demonstrated structural stability against hydrolysis by both serine- and metallo-β-lactamases, including clinically relevant carbapenemases such as Klebsiella pneumoniae carbapenemase, oxacillin carbapenemase-48, and New Delhi metallo-β-lactamase. Cefiderocol has demonstrated promising in vitro antibacterial and bactericidal activity, which correlates with its in vivo efficacy in several animal models. This article reviews the discovery and chemistry of cefiderocol, as well as some of the key microbiological and in vivo findings on cefiderocol from recently conducted investigations.

    Thu, 28 Dec 2017
    In a study of medical records gathered on hundreds of thousands of African-American women, Johns Hopkins researchers say they have evidence that women with a common form of hair loss have an increased chance of developing uterine leiomyomas, or fibroids.

    Wed, 20 Dec 2017

    The “mutational burden,” or the number of mutations present in a tumor’s DNA, is a good predictor of whether that cancer type will respond to a class of cancer immunotherapy drugs known as checkpoint inhibitors, a new study led by Johns Hopkins Kimmel Cancer Center researchers shows. The finding, published in the Dec. 21 New England Journal of Medicine, could be used to guide future clinical trials for these drugs.

    Mon, 18 Dec 2017
    In a study using genetically engineered mice, Johns Hopkins researchers have uncovered some new molecular details that appear to explain how electroconvulsive therapy (ECT) rapidly relieves severe depression in mammals, presumably including people. The molecular changes allow more communication between neurons in a specific part of the brain also known to respond to antidepressant drugs.

    2019-11-18
    According to the Occupational Health and Safety Risks in the Healthcare Sector guideline, 10% of workers in the European Union are employed in the health care industry, mostly in hospitals. In the performance of their jobs, however, health care workers (HCWs) are exposed to several workplace hazards, especially biological risks,1 which include infectious diseases. Moreover, there is also a risk that HCWs will spread diseases to colleagues and patients. The active immunization of HCWs is a primary prevention measure able to control and reduce the transmission of vaccine-preventable diseases (VPDs), particularly to patients at high risk (eg, those with cancer or immune deficits).

    2019-11-16
    We read the article titled “Current practice of infection control in Dutch primary care: Results of an online survey”1 with great interest. This study illustrates the need for infection prevention specialists in the outpatient setting, particularly physician offices. Physician offices can have a deceptively benign appearance in terms of infection prevention; however, history demonstrates differently.2 With physician offices, there are high-risk activities to consider, including reprocessing, injections, infusions, and procedures.

    2019-11-16
    We employed an interrupted time series analysis to assess the impact of ultraviolet-C light disinfection at terminal discharge in an oncology unit and a bone marrow transplant unit on the incidence of hospital-acquired infections. The deployment of ultraviolet-C light disinfection was associated with a significant decrease in the rate of Clostridioides difficile infections and a significant decrease in the rate of central line–associated blood stream infections in the bone marrow transplant unit.
