Substantial progress has been made in the standardization of nomenclature for paediatric and congenital cardiac care. In 1936, Maude Abbott published her Atlas of Congenital Cardiac Disease, which was the first formal attempt to classify congenital heart disease. The International Paediatric and Congenital Cardiac Code (IPCCC) is now utilized worldwide and has most recently become the paediatric and congenital cardiac component of the Eleventh Revision of the International Classification of Diseases (ICD-11). The most recent publication of the IPCCC was in 2017. This manuscript provides an updated 2021 version of the IPCCC.

The International Society for Nomenclature of Paediatric and Congenital Heart Disease (ISNPCHD), in collaboration with the World Health Organization (WHO), developed the paediatric and congenital cardiac nomenclature that is now within the eleventh version of the International Classification of Diseases (ICD-11). This unification of IPCCC and ICD-11 is the IPCCC ICD-11 Nomenclature and is the first time that the clinical nomenclature for paediatric and congenital cardiac care and the administrative nomenclature for paediatric and congenital cardiac care are harmonized. The resultant congenital cardiac component of ICD-11 was increased from 29 congenital cardiac codes in ICD-9 and 73 congenital cardiac codes in ICD-10 to 318 codes submitted by ISNPCHD through 2018 for incorporation into ICD-11. After these 318 terms were incorporated into ICD-11 in 2018, the WHO ICD-11 team added an additional 49 terms, some of which are acceptable legacy terms from ICD-10, while others provide greater granularity than the ISNPCHD thought was originally acceptable. Thus, the total number of paediatric and congenital cardiac terms in ICD-11 is 367. In this manuscript, we describe and review the terminology, hierarchy, and definitions of the IPCCC ICD-11 Nomenclature. This article, therefore, presents a global system of nomenclature for paediatric and congenital cardiac care that unifies clinical and administrative nomenclature.

The members of ISNPCHD realize that the nomenclature published in this manuscript will continue to evolve. The version of the IPCCC that was published in 2017 has evolved and changed, and it is now replaced by this 2021 version. In the future, ISNPCHD will again publish updated versions of IPCCC, as IPCCC continues to evolve.

The first demonstration of laser action in ruby was made in 1960 by T. H. Maiman of Hughes Research Laboratories, USA. Many laboratories worldwide began the search for lasers using different materials, operating at different wavelengths. In the UK, academia, industry and the central laboratories took up the challenge from the earliest days to develop these systems for a broad range of applications. This historical review looks at the contribution the UK has made to the advancement of the technology, the development of systems and components and their exploitation over the last 60 years.

Philosophers, archeologists, and other heritage professionals often take a rather negative view of heritage reconstruction, holding that it is inappropriate or even impermissible. In this essay, we argue that taking such hardline attitudes toward the reconstruction of heritage is unjustified. To the contrary, we believe that the reconstruction of heritage can be both permissible and beneficial, all things considered. In other words, sometimes we have good reasons, on balance, to pursue reconstructions, and doing so can be morally acceptable. In defending this claim, we discern a number of arguments made against heritage reconstruction and demonstrate that these arguments are either exaggerated or lack support.

Background: Candidemia is associated with high morbidity and mortality. Although risk factors for candidemia and other bloodstream infections (BSIs) overlap, little is known about patient characteristics and the outcomes of polymicrobial infections. We used data from the CDC Emerging Infections Program (EIP) candidemia surveillance to describe polymicrobial candidemia infections and to assess clinical differences compared with Candida-only BSIs. Methods: During January 2017–December 2017 active, population-based candidemia surveillance was conducted in 45 counties in 9 states covering ~6% of the US population through the CDC EIP. A case was defined as a blood culture with Candida spp in a surveillance-area resident; a blood culture >30 days from the initial culture was considered a second case. Demographic and clinical characteristics were abstracted from medical records by trained EIP staff. We examined characteristics of polymicrobial cases, in which Candida and ≥1 non-Candida organism were isolated from a blood specimen on the same day, and compared these to Candida-only cases using logistic regression or t tests using SAS v 9.4 software. Results: Of the 1,221 candidemia cases identified during 2017, 215 (10.2%) were polymicrobial. Among polymicrobial cases, 50 (23%) involved ≥3 organisms. The most common non-Candida organisms were Staphylococcus epidermidis (n = 30, 14%), Enterococcus faecalis (n = 26, 12%), Enterococcus faecium (n = 17, 8%), and Staphylococcus aureus, Klebsiella pneumoniae, and Stenotrophomonas maltophilia (n = 15 each, 7%). Patients with polymicrobial cases were significantly younger than those with Candida-only cases (54.3 vs 60.7 years; P < .0004). Healthcare exposures commonly associated with candidemia like total parenteral nutrition (relative risk [RR], 0.82; 95% CI, 0.60–1.13) and surgery (RR, 0.99; 95% CI, 0.77–1.29) were similar between the 2 groups. Polymicrobial cases had shorter median time from admission to positive culture (1 vs 4 days, P < .001), were more commonly associated with injection drug use (RR, 1.95; 95% CI, 1.46–2.61), and were more likely to be community onset-healthcare associated (RR, 1.91; 95% CI, 1.50–2.44). Polymicrobial cases were associated with shorter hospitalization (14 vs 17 days; P = .031), less ICU care (RR, 0.7; 95% CI, 0.51–0.83), and lower mortality (RR, 0.7; 95% CI, 0.50–0.92). Conclusions: One in 10 candidemia cases were polymicrobial, with nearly one-quarter of those involving ≥3 organisms. Lower mortality among polymicrobial cases is surprising but may reflect the younger age and lower severity of infection of this population. Greater injection drug use, central venous catheter use, and long-term care exposures among polymicrobial cases suggest that injection or catheter practices play a role in these infections and may guide prevention opportunities.

Background: Well-designed infection prevention programs include basic elements aimed at reducing the risk of transmission of infectious agents in healthcare settings. Although most acute-care facilities have robust infection prevention programs, data are sporadic and often lacking in other healthcare settings. Infection control assessment tools were developed by the CDC to assist health departments in assessing infection prevention preparedness across a wide spectrum of health care including acute care, long-term care, outpatient care, and hemodialysis. Methods: The North Carolina Division of Public Health collaborated with the North Carolina Statewide Program for Infection Control and Epidemiology (SPICE) to conduct a targeted number of on-site assessments for each healthcare setting. Three experienced infection preventionists recruited facilities, conducted on-site assessments, provided detailed assessment findings, and developed educational resources. Results: The goal of 250 assessments was exceeded, with 277 on-site assessments completed across 75% of North Carolina counties (Table 1). Compliance with key observations varied by domain and type of care setting (Table 2). Conclusions: Comprehensive on-site assessments of infection prevention programs are an effective way to identify gaps or breaches in infection prevention practices. Gaps identified in acute care primarily related to competency validation: however, gaps presenting a threat to patient safety (ie, reuse of single dose vials, noncompliance with sterilization and/or high-level disinfection processes) were identified in other care settings. Infection control assessment and response findings underscore the need for ongoing assessment, education, and collaboration among all healthcare settings.

CHD remains one of the leading causes of mortality of children in the United States. There is limited research about the experience of parents from the diagnosis of their child with CHD through the death of their child. A prior study has shown that adults with heart failure go through a series of four transitions: 1) learning the diagnosis, 2) reframing the new normal, 3) taking control of the illness, and 4) understanding death is inevitable. In our qualitative study, we performed semi-structured interviews with parents who have a child die of CHD to determine whether the four transitions in adults apply to parents of children with CHD. We found that these four transitions were present in the parents we interviewed and that there were two novel transitions, one that proceeded the first Jones et al transition (“Prenatal diagnosis”) and one that occurred after the final Jones et al transition (“Adjustment after death”). It is our hope that identification of these six transitions will help better support families of children with CHD.

The Antarctic Treaty of 1959, which dedicates the continent to peace and international scientific cooperation in the face of rising east–west tensions, is informed in part by a shared scientific imaginary created by the UK and other nations which maintained scientific bases in Antarctica at the time. In this article, the poet offers works extracted from her longer sequence “Met Obs,” based on meteorological reports and journals from the UK station at Port Lockroy written in advance of the 1957–1958 International Geophysical Year (IGY). The poems engage with the work and circumstances which helped foster such an imaginary, as well as with the nexus of Antarctic “values” endorsed by the Treaty, and the later Madrid Protocol. The commentary further contextualises these literary responses in terms of the attitudes of the men working there as well as the “wilderness and aesthetic values” recognised by the later Protocol on Environmental Protection. The world of the poems may belong to 1950s Antarctica, but their observations reach beyond that experience, making a case for the continued relevance of Treaty values, and for the importance of artistic, as well as scientific, responses to the environment in a world under threat from accelerating climate change and competition for resources.

As more debates in American politics become constitutional questions, effective citizens must engage in constitutional interpretation. While most Americans venerate the Constitution as a part of a national, civil religion, levels of constitutional knowledge are also very low. In this paper, we analyze how ordinary Americans approach the task of constitutional interpretation. An analysis of two cross-sectional surveys indicates constitutional hermeneutics are a product of political factors, religious affiliation, and biblical interpretive preferences. We also present the results of a survey experiment where the manipulation of a clergy's interpretation of a biblical passage affects how respondents interpret both scripture and the Constitution, providing a potential causal mechanism for learning how to engage in hermeneutics.
