Lyme disease is a complex tick-borne zoonosis that poses an escalating public health threat in several parts of the world, despite sophisticated healthcare infrastructure and decades of effort to address the problem. Concepts like the true burden of the illness, from incidence rates to longstanding consequences of infection, and optimal case management, also remain shrouded in controversy. At the heart of this multidisciplinary issue are the causative spirochetal pathogens belonging to the Borrelia Lyme complex. Their unusual physiology and versatile lifestyle have challenged microbiologists, and may also hold the key to unlocking mysteries of the disease. The goal of this review is therefore to integrate established and emerging concepts of Borrelia biology and pathogenesis, and position them in the broader context of biomedical research and clinical practice. We begin by considering the conventions around diagnosing and characterizing Lyme disease that have served as a conceptual framework for the discipline. We then explore virulence from the perspective of both host (genetic and environmental predispositions) and pathogen (serotypes, dissemination, and immune modulation), as well as considering antimicrobial strategies (lab methodology, resistance, persistence, and clinical application), and borrelial adaptations of hypothesized medical significance (phenotypic plasticity or pleomorphy).

Objectives The British honours system is one of the oldest in the world rewarding individuals, including those of the medical profession. The authors were interested to see if any particular specialty was honoured to a greater extent. We aimed to establish the number of those honoured, the duration of clinical practice involved, as well as additional factors. Design A retrospective analysis of doctors receiving honours (Knight/Dame, CBE, OBE, MBE) in the last decade was performed. Setting UK-registered doctors. Participants Doctors were identified from publicly available listings. Main outcome measures Demographics of all honoured doctors, including number of years of service, specialty affiliation and the number of recipients holding professorial status were collected. Clinicians were stratified into four subgroups: General Practitioners, Physicians, Surgeons and Others. Data were analysed using parametric statistical tests. Results Four hundred and seventeen doctors were identified. Four hundred and two clinicians had a documented subspecialty affiliation. Of the 402: GPs ( n = 142), Physicians ( n = 100), Surgeons ( n = 34) and Others ( n = 126). The number of years in clinical practice from registration to conference of honours was significantly shorter for GPs when compared to hospital-based specialties ( P < 0.05). The top 10 specialties of individuals honoured are tabulated. Professors constituted 30% ( n = 131) of those honoured. These individuals were sub-divided according to specialty affiliation with a significant difference observed ( P < 0.05). Conclusions The most honoured specialty was General Practice. However, when corrected for total subspecialty population, the number one ranking specialty was Public Health Medicine. Academic clinicians are well represented. The findings may be of interest to the medical community.

The Zika virus (ZIKV), first discovered in 1947, has emerged as a global public health threat over the last decade, with an accelerated geographic spread of the virus occurring in the last 5 years. The World Health Organization (WHO) predicts that millions of cases of ZIKV are likely to occur in the Americas between 2016 and 2017. These projections, in conjunction with an increase in newborn microcephaly cases that are suspected to be ZIKV-associated, prompted the WHO to declare a public health emergency of international concern in February 2016. With the current media attention, it is likely that GPs will be consulted on th topic, particularly by pregnant women.

BACKGROUND One of the key mandates of the World Health Organization (WHO) is to develop guidelines, defined as “a document containing recommendations for clinical practice or public health policy.” Guidelines represent the global standard for information sources shaping clinical practice and public health policies. Despite the rigorous development process and the value of guidelines for setting standards, implementing such standards within local contexts and at the point of care is a well-documented challenge. Digital technologies enable agile information management and may facilitate the adaptation of guidelines to diverse settings of health services delivery. OBJECTIVE The objective of this paper is to detail the systematic and iterative process involved in transforming the WHO Antenatal Care (ANC) guidelines into a digital decision-support and patient-record application for routine use in primary health care settings, known as the WHO digital ANC module. METHODS The WHO convened a team of clinical and digital health experts to develop the WHO digital ANC module as a tool to assist health care professionals in the implementation of WHO evidence-based recommendations for pregnant women. The WHO digital ANC module’s creation included the following steps: defining a minimum viable product (MVP), developing clinical workflows and algorithms, algorithm testing, developing a data dictionary, and the creation of a user interface or application development. The overall process of development took approximately 1 year to reach a stable prototype and to finalize the underlying content requirements of the data dictionary and decision support algorithms. RESULTS The first output is a reference software reflecting the generic WHO ANC guideline content, known as the WHO digital ANC module. Within it, all actionable ANC recommendations have related data fields and algorithms to confirm whether the associated task was performed. WHO recommendations that are not carried out by the health care worker are saved as pending tasks on a woman’s health record, and those that are adequately fulfilled trigger messages with positive reinforcement. The second output consists of the structured documentation of the different components which contributed to the development of the WHO digital ANC module, such as the data dictionary and clinical decision support workflows. CONCLUSIONS This is a novel approach to facilitate the adoption and adaptation of recommendations through digital systems at the health service delivery level. It is expected that the WHO digital ANC module will support the implementation of evidence-based practices and provide information for monitoring and surveillance; however, further evidence is needed to understand how the WHO digital ANC module impacts the implementation of WHO recommendations. Further, the module’s implementation will inform the WHO’s ongoing efforts to create a pathway to adaptive and integrated (Smart) Guidelines in Digital Systems to improve health system quality, coverage, and accountability.

Background: The World Health Organization's aim to eliminate hepatitis C virus (HCV) infection as a public health threat by 2030 is dependent on testing people. HCV prevalence is higher in prisons, so to increase test uptake an ‘opt-out’ approach to blood-borne virus testing in English and Welsh prisons was introduced. Aims: This literature review examines the evidence behind the introduction of this public health policy. Methods: Four healthcare databases were searched for publications between January 2000 and February 2020 on the opt-out approach to blood-borne virus testing in prisons. Findings: Sixteen studies published between 2009 and 2019 were included. Analysis of their findings showed that an increase in HCV test uptake in prisons occurs when an opt-out approach is used in combination with additional interventions. Contextual differences between UK and US prisons may affect HCV test uptake. Conclusion: An opt-out approach to HCV testing in prisons can increase test uptake as part of a complex of interventions.

Abstract Background The World Health Organisation (WHO) publishes a large number of clinical practice and public health guidelines to promote evidence-based practice across the world. Due to the variety of health system capacities and contextual issues in different regions and countries, adapting the recommendations in the guidelines to the local situation is vital for the success of their implementation. We aim to understand the range of experiences with guideline adaptation from the perspectives of those working in WHO regional and country offices. Our findings will inform development of guidance on how to improve adaptability of WHO guidelines. Methods A grounded theory-informed, qualitative study was carried out between March 2018 and December 2018. Seventeen semi-structured interviews were conducted with participants who included WHO guideline developers and staff in the headquarters, regional and country offices recruited from a sample of published WHO guidelines. Participants were eligible for recruitment if they had recent experience in clinical practice or public health guideline implementation. Deidentified transcripts of these interview were analysed through three cycles of coding. Results We categorised the adaptation processes described by the participants into two dominant models along a spectrum of guideline adaptation processes. First, the Copy or Customise Model is a pragmatic approach of either copying or customising WHO guidelines to suit local needs. This is done by local health authorities and/or clinicians directly through consultations with WHO staff. Selections and adjustments of guideline recommendations are made according to what the implementers deemed important, feasible and applicable through the consensus discussions. Second, the Capacity Building Model focuses on WHO building local capacity in evidence synthesis methods and adaptation frameworks to support local development of a national guideline informed by international guidelines. Conclusions In comparing and contrasting these two models of guideline adaptation, we outline the different kinds of support from WHO that may be necessary to improve the effectiveness and efficiency of the respective models. We also suggest clarifications in the descriptions of the process of guideline adaptation in WHO and academic literature, to help guideline adaptors and implementers decide on the appropriate course of action according to their specific circumstances. Ethics This project was conducted with ethics approval from The University of Sydney (Project number: 2017/723) and WHO (Protocol ID: 00001).

Rabies remains a major public health threat around the world. Once symptoms appear, there is no effective treatment to prevent death. In this work, we tested a recombinant parainfluenza virus 5 (PIV5) strain expressing the glycoprotein (G) of rabies (PIV5-G) as a therapy for rabies virus infection: we have found that PIV5-G protected mice as late as 6 days after rabies virus infection. PIV5-G is a promising vaccine for prevention and treatment of rabies virus infection.

The coronavirus disease (COVID-19) has emerged as the latest and serious public health threat throughout the world. In the absence of prevention and rehabilitation interventions, different countries have implemented shutdown and/or lockout policies to monitor the transmission of the epidemic, resulting of a significant reduction in anthropogenic activities. As a result, this kind of phenomenon is helped to inhibit the environmental degradation activity by reducing various pollutants from the air, water and soil. This condition provided ‘a once-in-a-lifetime’ chance for nature to evolve and recover. This paper discusses the nature of which in terms of its beneficial effect on water, air, the ozone layer, and waste deposition. Finally, the article also presents certain suggestive measures by highlighting the role of government, educational institutes, and a person as a whole in the sustenance of nature under pandemic. Based on the reported effect of the pandemic on the environment, it can be inferred that nature, with or without human intervention, can repair itself to some degree. However, human beings need to aware of saving and supporting to nature instead of involving in constant degradation.
