Exebacase in Addition to Standard-of-Care Antibiotics for Staphylococcus aureus Bloodstream Infections and Right-Sided Infective Endocarditis: A Phase 3, Superiority-Design, Placebo-Controlled, Randomized Clinical Trial (DISRUPT).

Background: Novel treatments are needed for Staphylococcus aureus bacteremia, particularly for methicillin-resistant S. aureus (MRSA). Exebacase is a first-in-class antistaphylococcal lysin that is rapidly bactericidal and synergizes with antibiotics.

Rapid bacteriolysis of by lysin exebacase.

Lysins (peptidoglycan hydrolases) are promising new protein-based antimicrobial candidates under development to address rising antibiotic resistance encountered among pathogenic bacteria. Exebacase is an antistaphylococcal lysin and the first member of the lysin class to have entered clinical trials in the United States. In this study, the bacteriolytic activity of exebacase was characterized with time-kill assays, turbidity reduction assays, and microscopy.

Paediatric palliative care for the generalist.

Palliative care has been defined as 'the active holistic care of individuals across all ages with serious health-related suffering due to severe illness, and especially of those near the end of life'. Unfortunately, palliative care and especially paediatric palliative care remain a neglected area of medicine and are widely misunderstood, with few healthcare providers having any formal training in South Africa. To relieve health-related suffering, healthcare providers must understand that the field is not limited to end-of-life care for the terminally ill, and holistic care (physical, emotional, social and spiritual) should commence at the time of diagnosis of a serious illness.

The Lysin Exebacase Has a Low Propensity for Resistance Development in Staphylococcus aureus and Suppresses the Emergence of Resistance to Antistaphylococcal Antibiotics.

Exebacase (CF-301) belongs to a novel class of protein-based antibacterial agents, called lysins (peptidoglycan hydrolases). Exebacase exhibits potent antistaphylococcal activity and is the first lysin to initiate clinical trials in the United States. To support clinical development, the potential for resistance development to exebacase was assessed over 28 days of serial daily subculture in the presence of increasing concentrations of the lysin performed in its reference broth medium.

Exploring the experiences of healthcare professionals in South Africa and Uganda around communicating with children about life-threatening conditions: a workshop-based qualitative study to inform the adaptation of communication frameworks for use in these settings.

Objectives: This study aimed to explore how published communication frameworks could be amended to ensure applicability and cultural appropriateness for professionals to support family-centred conversations by investigating' healthcare professionals' (1) experiences of providing support to families when a caregiver or a dependent child (<18 years old) has a life-threatening condition, (2) perceived challenges for caregivers and healthcare professionals in communicating with children about illness, (3) perceptions of how clinicians could be equipped to facilitate conversations between caregivers and children about an adult or the child's own life-threatening condition and (4) suggestions for amendments to previously published guidelines to ensure cultural relevance in South Africa and Uganda.

Design: A qualitative study involving two 2-day workshops with embedded focus group discussions, break out rooms and consensus discussions.

Setting: Health and social care and third sector organisations in South Africa and Uganda.

Position paper on undergraduate Palliative Medicine education for doctors in South Africa.

Background:  Basic palliative care teaching should be included in training curricula for health care providers (HCPs) at all levels of the health service to ensure that the goal set by the South African (SA) National Policy Framework and Strategy for Palliative Care, to have an adequate number of appropriately trained HCPs in South Africa, is achieved. Furthermore, palliative learning objectives for nurses and doctors should be standardised. Many SA medical schools have integrated elements of Palliative Medicine (PM) teaching into undergraduate medical training programmes for doctors; however, the degree of integration varies widely, and consensus and standardisation of the content, structure and delivery of such PM training programmes are not yet a reality.

DNA-Dependent Binding of Nargenicin to DnaE1 Inhibits Replication in .

Natural products provide a rich source of potential antimicrobials for treating infectious diseases for which drug resistance has emerged. Foremost among these diseases is tuberculosis. Assessment of the antimycobacterial activity of nargenicin, a natural product that targets the replicative DNA polymerase of , revealed that it is a bactericidal genotoxin that induces a DNA damage response in () and inhibits growth by blocking the replicative DNA polymerase, DnaE1.

Community-driven tree planting greens the neighbouring landscape.

Nature-based solutions to climate change are growing policy priorities yet remain hard to quantify. Here we use remote sensing to quantify direct and indirect benefits from community-led agroforestry by The International Small group and Tree planting program (TIST) in Kenya. Since 2005, TIST-Kenya has incentivised smallholder farmers to plant trees for agricultural benefit and to sequester CO.

Determination of MIC Quality Control Parameters for Exebacase, a Novel Lysin with Antistaphylococcal Activity.

Exebacase (CF-301), a novel, antistaphylococcal lysin (cell wall hydrolase) is the first agent of this class to enter late-stage clinical development (phase 3, NCT04160468) for the treatment of Staphylococcus aureus bacteremia, including right-sided endocarditis. A multilaboratory Clinical and Laboratory Standards Institute (CLSI) M23-defined tier 2 quality control (QC) study was conducted to establish exebacase QC ranges for a new reference broth microdilution method. S.

Development of a Broth Microdilution Method for Exebacase Susceptibility Testing.

Exebacase (CF-301) belongs to a new class of protein-based antibacterial agents, known as lysins (peptidoglycan hydrolases). Exebacase, a novel lysin with antistaphylococcal activity, is in phase 3 of clinical development. To advance into the clinic, it was necessary to develop an accurate and reproducible method for exebacase MIC determination.

TBDBT: A TB DataBase Template for collection of harmonized TB clinical research data in REDCap, facilitating data standardisation for inter-study comparison and meta-analyses.

Clinical tuberculosis research, both within research groups and across research ecosystems, is often undertaken in isolation using bespoke data collection platforms and applying differing data conventions. This failure to harmonise clinical phenotype data or apply standardised data collection and storage standards in turn limits the opportunity to undertake meta-analyses using data generated across multiple research projects for the same research domain. We have developed the Tuberculosis DataBase Template (TBDBT), a template for the well-supported, free and commonly deployed clinical databasing platform, REDCap.

Palliation, end-of-life care and burns; practical issues, spiritual care and care of the family - A narrative review II.

Palliative care is the turn from cure as the priority of care to symptom relief and comfort care. Although very little is published in the burn literature on palliative care, guidelines can be gleaned from the general literature on palliative care, particularly for acute surgical and critical care patients. This second article discusses practical issues around palliative care for burn patients, such as pain and fluid management, withdrawal of ventilator support and wound care, as well as spiritual and family issues.

Equitable Science Requires Collegial Debate.

We welcome an ongoing debate about benefit-sharing related to the use of digital sequence information (DSI) and how to ensure global equity in the use of biological samples, including those donated by human beings.

Including Digital Sequence Data in the Nagoya Protocol Can Promote Data Sharing.

The Nagoya Protocol (NP), a legal framework under the Convention on Biological Diversity (CBD), formalises fair and equitable sharing of benefits arising from biological diversity. It encompasses biological samples and associated indigenous knowledge, with equitable return of benefits to those providing samples. Recent proposals that the use of digital sequence information (DSI) derived from samples should also require benefit-sharing under the NP have raised concerns that this might hamper research progress.

GenGraph: a python module for the simple generation and manipulation of genome graphs.

Background: As sequencing technology improves, the concept of a single reference genome is becoming increasingly restricting. In the case of Mycobacterium tuberculosis, one must often choose between using a genome that is closely related to the isolate, or one that is annotated in detail. One promising solution to this problem is through the graph based representation of collections of genomes as a single genome graph.

Qualitative situational analysis of palliative care for adolescents with cancer and HIV in South Africa: healthcare worker perceptions.

Objectives: The unmet palliative care need is intensified in resource-limited countries where there is inequitable access to healthcare and adolescents and young adults (AYA) fall between the cracks of paediatric and adult services. We aimed to examine palliative care for AYA with cancer and/or HIV in South Africa.

Design: Individual and small group interviews using process mapping.

Inspiration, innovation and integration: highlights from the third ICPCN conference on children's palliative care, 30 May to 2 June 2018, Durban, South Africa.

The International Children's Palliative Care Network (ICPCN) held its third international conference on children's palliative care in Durban, South Africa, from May 30 2018 to 2 June 2018. The conference-inspiration, innovation and integration-brought together 250 participants from 41 countries and was held in conjunction with local partners-Umduduzi Hospice Care for Children, Palliative Treatment for Children South Africa (Patch SA) and the Hospice and Palliative Care Association of South Africa. It built on national and global developments in palliative care such as its inclusion in Universal health coverage (UHC), the Lancet Commission report on pain and palliative care and the sustainable development goals (SDGs), and aimed to raise the profile of children's palliative care in KwaZulu-Natal (KZN) and nationally.

EPHA2 sequence variants are associated with susceptibility to Kaposi's sarcoma-associated herpesvirus infection and Kaposi's sarcoma prevalence in HIV-infected patients.

Background: To determine if variations exist in the KSHV host receptor EPHA2's coding region that affect KSHV infectivity and/or KS prevalence among South African HIV-infected patients.

Methods: A retrospective candidate gene association study was performed on 150 patients which were randomly selected from a total of 756 HIV-infected patients and grouped according to their KS status and KSHV serodiagnosis; namely group 1: KS/KSHV; group 2: KS/KSHV; group 3: KS/KSHV. Peripheral blood DNA was used to extract DNA and PCR amplify and sequence the entire EPHA2 coding region, which was compared to the NCBI reference through multiple alignment.

CLSI Methods Development and Standardization Working Group Best Practices for Evaluation of Antimicrobial Susceptibility Tests.

Effective evaluations of antimicrobial susceptibility tests (ASTs) require robust study design. The Clinical and Laboratory Standards Institute (CLSI) Subcommittee on Antimicrobial Susceptibility Testing has recognized that many published studies reporting the performance of commercial ASTs (cASTs) suffer from major design and/or analysis flaws, rendering the results difficult or impossible to interpret. This minireview outlines the current consensus of the Methods Development and Standardization Working Group of the CLSI Subcommittee on Antimicrobial Susceptibility Testing regarding best practices for systematic evaluation of the performance of an AST, including the analysis and presentation of essential data intended for publication.

Ceftaroline efficacy against high-MIC clinical Staphylococcus aureus isolates in an in vitro hollow-fibre infection model.

Objectives: The current CLSI and EUCAST clinical susceptible breakpoint for 600 mg q12h dosing of ceftaroline (active metabolite of ceftaroline fosamil) for Staphylococcus aureus is ≤1 mg/L. Efficacy data for S. aureus infections with ceftaroline MIC ≥2 mg/L are limited.
