ABSTRACT

OBJECTIVE: Social determinants of health, including the effects of neighborhood disadvantage, impact epilepsy prevalence, treatment, and outcomes. This study characterized the association between aberrant white matter connectivity in temporal lobe epilepsy (TLE) and disadvantage using a US census-based neighborhood disadvantage metric, the Area Deprivation Index (ADI), derived from measures of income, education, employment, and housing quality.

METHODS: Participants including 74 TLE patients (47 male, mean age=39.2) and 45 healthy controls (27 male, mean age=31.9) from the Epilepsy Connectome Project were classified into ADI-defined low and high disadvantage groups. Graph theoretic metrics were applied to multi-shell connectome diffusion weighted imaging (DWI) measurements in order to derive 162 x 162 structural connectivity matrices (SCMs). The SCMs were harmonized using neuroCombat to account for interscanner differences. Threshold-free network-based statistics were used for analysis and findings were correlated with ADI quintile metrics. A decrease in cross-sectional areas (CSA) indicate reduced white matter integrity.

RESULTS: Sex and age-adjusted CSA in TLE groups were significantly reduced compared to controls regardless of disadvantage status, revealing discrete aberrant white matter tract connectivity abnormalities in addition to apparent differences in graph measures of connectivity and network-based statistics. When comparing broadly defined disadvantaged TLE groups, differences were at trend-level. Sensitivity analyses of ADI quintile extremes revealed significantly lower CSA in the most compared to least disadvantaged TLE group.

SIGNIFICANCE: Our findings demonstrate: 1) the general impact of TLE on DWI connectome status is larger than the association with neighborhood disadvantage; however, 2) neighborhood disadvantage, indexed by ADI, revealed modest relationships to white matter structure and integrity on sensitivity analysis in TLE. Further studies are needed to explore this relationship and determine if the white matter relationship with ADI is driven by social drift or environmental influences on brain development. Understanding the etiology and course of the disadvantage-brain integrity relationship may serve to inform care, management, and policy for patients.

ABSTRACT

AIMS: To analyse the compliments received from patients’ and companions and to describe the characteristics of high-quality nursing and midwifery care from the perspective of healthcare consumers.

DESIGN: Retrospective analysis of health service compliments data.

METHODS: All compliments specific to nursing and midwifery care received between July 2020 and June 2021 were extracted from the reporting database for six hospital sites of a large public health service in Victoria, Australia. Inductive coding captured the characteristics and qualities of nurses and midwives elicited from the compliments. Deductive coding used two frameworks: an adapted health complaints assessment tool, and 10 dimensions of nursing and midwifery care used in the health service. Descriptive statistics were used for analysis of coded data.

RESULTS: Of the 2833 records identified, 433 nursing and midwifery-specific compliments were identified; of these 225 consumer or care partner compliments were identified for analysis. Most compliments (80.4%, n = 181) were from the smaller hospital sites compared to 19.6% (n = 44) received at the largest hospital site; and from care programmes that typically care for older patients (42.7%, n = 113). Only 39% (n = 89) of compliments related to quality and safety of clinical care, 9% (n = 21) related to management and 17% (n = 38) to relationships. Forty-nine percent (n = 113) related to dimensions of fundamental nursing and midwifery care, with psychological care best represented (39.8%, n = 89). Most often, compliments related to characteristics or attributes of nurses.

CONCLUSION: Analysis of compliments reveals characteristics of nursing and midwifery care valued by healthcare consumers. Surprisingly, few compliments related to clinical dimensions of nursing and midwifery practice. Comments related to psychological aspects of nursing and midwifery care were most common. Understanding consumer perceptions of high-quality care provided by nurses and midwives provide guidance about care delivery that meets or exceed consumer expectations. The findings suggest low consumer awareness about professional and clinical aspects of nursing and midwifery work.

IMPACT: Compliments provide a unique insight into consumer perspectives of high-quality nursing and midwifery care. When making compliments, consumers most often commented about the attributes and characteristics of nurses and midwives, rather than clinical aspects of care. Compliments specific to nursing and midwifery care provide guidance to enhance care delivery to meet or exceed consumer expectations.

ABSTRACT

AIM: To describe psychometric validation of the newly developed Advanced Practice Nurse Task Questionnaire.

DESIGN: Cross-sectional quantitative study.

METHODS: The development of the questionnaire followed an adapted version of the seven steps described in the guide by the Association for Medical Education in Europe. A nationwide online survey tested the construct and structural validity and internal consistency using an exploratory factor analysis, Cronbach’s alpha coefficient and a Kruskal-Wallis test to compare the hypotheses.

RESULTS: We received 222 questionnaires between January and September 2020. The factor analysis produced a seven-factor solution as suggested in Hamric’s model. However, not all item loadings aligned with the framework’s competencies. Cronbach’s alpha of factors ranged between .795 and .879. The analysis confirmed the construct validity of the Advanced Practice Nurse Task Questionnaire. The tool was able to discriminate the competencies of guidance and coaching, direct clinical practice and leadership across the three advanced practice nurse roles clinical nurse specialist, nurse practitioner or blended role.

CONCLUSION: A precise assessment of advanced practice nurse tasks is crucial in clinical practice and in research as it may be a basis for further refinement, implementation and evaluation of roles.

IMPACT: The Advanced Practice Nurse Task Questionnaire is the first valid tool to assess tasks according to Hamric’s model of competencies independently of the role or the setting. Additionally, it distinguishes the most common advanced practice nurse roles according to the degree of tasks in direct clinical practice and leadership. The tool may be applied in various countries, independent of the degree of implementation and understanding of advanced nursing practice.

REPORTING METHOD: The STARD 2015 guideline was used to report the study.

PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

ABSTRACT

In May 2022, for the first time, multiple cases of mpox were reported in several non-endemic countries. The first ever case of the disease in Greece was confirmed on 8 June 2022, and a total of 88 cases were reported in the country until the end of April 2023. A multidisciplinary response team was established by the Greek National Public Health Organization (EODY) to monitor and manage the situation. EODY’s emergency response focused on enhanced surveillance, laboratory testing, contact tracing, medical countermeasures, and the education of health care providers and the public. Even though management of cases was considered successful and the risk from the disease was downgraded, sporadic cases continue to occur. Here, we provide epidemiological and laboratory features of the reported cases to depict the course of the disease notification rate. Our results suggest that measures for raising awareness as well as vaccination of high-risk groups of the population should be continued.

ABSTRACT

During the early stages of the UK 2021-2022 H5N1 high-pathogenicity avian influenza virus (HPAIV) epizootic in commercial poultry, 12 infected premises (IPs) were confirmed by four real-time reverse-transcription-polymerase chain reaction (RRT)-PCRs, which identified the viral subtype and pathotype. An assessment was undertaken to evaluate whether a large sample throughput would challenge laboratory capacity during an exceptionally large epizootic; hence, assay performance across our test portfolio was investigated. Statistical analysis of RRT-PCR swab testing supported it to be focused on a three-test approach, featuring the matrix (M)-gene, H5 HPAIV-specific (H5-HP) and N1 RRT-PCRs, which was successfully assessed at 29 subsequent commercial IPs. The absence of nucleotide mismatches in the primer/probe binding regions for the M-gene and limited mismatches for the H5-HP RRT-PCR underlined their high sensitivity. Although less sensitive, the N1 RRT-PCR remained effective at flock level. The analyses also guided successful surveillance testing of apparently healthy commercial ducks from at-risk premises, with pools of five oropharyngeal swabs tested by the H5-HP RRT-PCR to exclude evidence of infection. Serological testing at anseriform H5N1 HPAIV outbreaks, together with quantitative comparisons of oropharyngeal and cloacal shedding, provided epidemiological information concerning the chronology of initial H5N1 HPAIV incursion and onward spread within an IP.

ABSTRACT

Respiratory viral infections are a leading global cause of disease with multiple viruses detected in 20-30% of cases, and several viruses simultaneously circulating. Some infections with unique viral copathogens result in reduced pathogenicity, while other viral pairings can worsen disease. The mechanisms driving these dichotomous outcomes are likely variable and have only begun to be examined in the laboratory and clinic. To better understand viral-viral coinfections and predict potential mechanisms that result in distinct disease outcomes, we first systematically fit mathematical models to viral load data from ferrets infected with respiratory syncytial virus (RSV), followed by influenza A virus (IAV) after 3 days. The results suggest that IAV reduced the rate of RSV production, while RSV reduced the rate of IAV infected cell clearance. We then explored the realm of possible dynamics for scenarios that had not been examined experimentally, including a different infection order, coinfection timing, interaction mechanisms, and viral pairings. IAV coinfection with rhinovirus (RV) or SARS-CoV-2 (CoV2) was examined by using human viral load data from single infections together with murine weight-loss data from IAV-RV, RV-IAV, and IAV-CoV2 coinfections to guide the interpretation of the model results. Similar to the results with RSV-IAV coinfection, this analysis shows that the increased disease severity observed during murine IAV-RV or IAV-CoV2 coinfection was likely due to the slower clearance of IAV-infected cells by the other viruses. The improved outcome when IAV followed RV, on the other hand, could be replicated when the rate of RV infected cell clearance was reduced by IAV. Simulating viral-viral coinfections in this way provides new insights about how viral-viral interactions can regulate disease severity during coinfection and yields testable hypotheses ripe for experimental evaluation.

ABSTRACT

BACKGROUND: Over the last two decades, honey bees (Apis mellifera) have suffered high rates of colony losses that have been attributed to a variety of factors, chief among which are viral pathogens, such as deformed wing virus (DWV), whose virulence has increased because of vector-based transmission by the invasive, ectoparasitic varroa mite (Varroa destructor). A shift in the experimental mode of transmission of the black queen cell virus (BQCV) and sacbrood virus (SBV) from fecal/food-oral (direct horizontal) to vector-mediated (indirect horizontal) transmission also results in high virulence and viral titers in pupal and adult honey bees. Agricultural pesticides represent another factor that acts independently or in interaction with pathogens, and they are also thought to cause colony loss. Understanding the molecular mechanisms underlying the higher virulence following a vector-based mode of transmission provides deeper insight into honey bee colony losses, as does determining whether or not host-pathogen interactions are modulated by exposure to pesticides.

METHODS: Through an experimental design with controlled laboratory, we investigated the effects of the modes of transmission of BQCV and SBV (feeding vs. vector-mediated via injection) alone or in combination with chronic exposure to sublethal and field-realistic concentrations of flupyradifurone (FPF), a novel agricultural insecticide, on honey bee survival and transcription responses by using high-throughput RNA sequencing (RNA-seq) analysis.

RESULTS: Co-exposure to viruses via feeding (VF) or injection (VI) and FPF insecticide had no statistically significant interactive effect on their survival compared to, respectively, VF or VI treatments alone. Transcriptomic analysis revealed a distinct difference in the gene expression profiles of bees inoculated with viruses via injection (VI) and exposed to FPF insecticide (VI+FPF). The number of differentially expressed genes (DEGs) at log2 (fold-change) > 2.0 in VI bees (136 genes) or/and VI+FPF insecticide (282 genes) was very high compared to that of VF bees (8 genes) or the VF+FPF insecticide treatment (15 genes). Of these DEGs, the expression in VI and VI+FPF bees of some immune-related genes, such as those for antimicrobial peptides, Ago2, and Dicer, was induced. In short, several genes encoding odorant binding proteins, chemosensory proteins, odor receptors, honey bee venom peptides, and vitellogenin were downregulated in VI and VI+FPF bees.

CONCLUSIONS: Given the importance of these suppressed genes in honey bees’ innate immunity, eicosanoid biosynthesis, and olfactory associative function, their inhibition because of the change in the mode of infection with BQCV and SBV to vector-mediated transmission (injection into haemocoel) could explain the high virulence observed in these viruses when they were experimentally injected into hosts. These changes may help explain why other viruses, such as DWV, represent such a threat to colony survival when transmitted by varroa mites.

ABSTRACT

AIM: This study evaluated the relationship between the systemic immune-inflammatory index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) with clinical findings of respiratory syncytial virus (RSV) infection among children with a diagnosis of lower respiratory tract infection (LRTI).

METHODS: The study was conducted between 1 January 2020 and 1 January 2022 in a pediatric clinic. This retrospective study included 286 consecutive patients between 0 and 12 years of age, 138 of whom were RSV (+) (48.25%) and 148 of whom were RSV (-) (51.75%). The detection of the RSV antigen was carried out using the chromatographic immunoassay method on nasopharyngeal swabbing samples.

RESULTS: CRP content was significantly higher in patients with RSV (+) than in children with RSV (-), while NLR, PLR, and SII, as inflammatory parameters, were significantly lower. Fever, coughs, and wheezing were the most common symptoms in the RSV (+) groups (100%). RSV infections were the highest in November, October, and December, in that order. The AUC was statistically significant for parameters in all groups. AUC values were 0.841 (95%: 0.765-0.917) for leukocytes, 0.703 (95%: 0.618-0.788) for lymphocytes, 0.869 (95%: 0.800-0.937) for CRP, 0.706 (95%: 0.636-0.776) for NLR, 0.779 (95%: 0.722-0.836) for PLR, and 0.705 (95%: 0.633-0.776) for SII. CRP was found to have both high sensitivity (80.4%) and high specificity (82.4%) among all parameters. While the ROC analysis results showed similar results for children under two years old, only CRP and NLR were statistically significant in this group.

CONCLUSION: CRP performed better than other blood parameters as a marker. The NLR, PLR, and SII index were significantly lower in LRTI patients with RSV (+) than in those with RSV (-), which implies a higher grade of inflammation. If the cause of the disease can be determined by this method, disease management will be easier, and unnecessary antibiotics could be avoided.

ABSTRACT

The first case of ASF in a domestic pig population in Serbia was confirmed in 2019 in a backyard population. Today, outbreaks in wild boar and, more importantly, in domestic pigs are still occurring, although the government measures for ASF prevention are in place. The aim of this study was to determine critical risk factors and identify the possible reasons for ASF introduction into different extensive pig farms. The study was conducted on 26 extensive pig farms with confirmed ASF outbreaks, with data collected from beginning of 2020 to the end of 2022. Collected epidemiological data were divided into 21 main categories. After identifying specific values of variables as critical for ASF transmission, we identified nine important ASF transmission indicators as those variables for which at least 2/3 of the observed farms reported values critical for ASF transmission. Among them were type of holding, distance to hunting ground, farm/yard fencing, and home slaughtering; however, the hunting activity of pig holders, swill feeding, and feeding with mowed green mass were not included. We represented the data in the form of contingency tables to study associations between pairs of variables using Fisher’s exact test. All pairs of variables in the group including type of holding, farm/yard fencing, domestic pig-wild boar contact, and hunting activity were significantly related; hunting activity of pig holders, holding pigs in backyards, unfenced yards, and domestic pig-wild boar contact were observed on the same farms. Free-range pig farming led to observed domestic pig-wild boar contact on all farms. The identified critical risk factors need to be strictly addressed to prevent the further spread of ASF to extensive farms and backyards in Serbia and elsewhere.

ABSTRACT

BACKGROUND: Nylon 11 is a synthetic plastic widely used in commercial products such as tubing for automobiles, offshore oilfields, and medical devices. An increasing amount of nylon and other plastic wastes have been released into various environments, posing ecological threats. The biodegradation of bundled nylon polymers has been considered impossible due to their crystalline structures.

METHODS: Nylon 11 film was created and incubated with adult mealworms. The mass, as well as structures, of nylon 11 films at pre- and post-incubation with beetles were compared. The number of nylon 11 monomer degrading bacteria in feces were determined by culture-dependent approach. The t-test was utilized to examine the statistical significance.

RESULTS: We discovered that adult mealworm (Tenebrio molitor) beetle can ingest nylon 11 when stretched thin. The microscopic observation of their feces did not identify the presence of large fragments of nylon 11. The analysis of fecal bacteria revealed that while the total number of culturable bacteria did not change significantly, the number of 11-aminoundecanoic acid-metabolizing bacteria increased by 10,000-fold.

CONCLUSIONS: Our results suggest that bundled nylon 11 polymers were fragmented into smaller pieces, including monomeric units (11-aminoundecanoic acid) by adult mealworm. The monomers seem to have supported the proliferation of gut microbial communities capable of utilizing 11-aminoundecanoic acid as a carbon and nitrogen source. Our work implies the potential use of the mealworm beetle as a means to fragment nylon polymers for remediation applications.
