RESUMEN
Background: To address antimicrobial resistance, antimicrobial stewardship (AMS) principles must be implemented and adhered to. Clinical decision aids such as the MicroGuideTM app are an important part of these efforts. We sought to evaluate the consistency of core AMS information and the diversity of classification thresholds for healthcare-associated pneumonia (HAP) in the MicroGuide app. Methods: Guidelines in the MicroGuide app were extracted and analysed for content related to AMS and HAP. Guidelines were characterized according to HAP naming classification; community-acquired pneumonia (CAP) classifications were analysed to serve as a comparator group. Results: In total, 115 trusts (119 hospitals) were included. Nearly all hospitals had developed MicroGuide sections on AMS (nâ=â112/119, 94%) and sepsis management (nâ=â117/119, 98%). Other AMS sections were outpatient parenteral antimicrobial therapy (47%), antifungal stewardship (70%), critical care (23%) and IV to oral switch therapy (83%). Only 9% of hospitals included guidance on the maximum six key AMS sections identified. HAP definitions varied widely across hospitals with some classifying by time to onset and some classifying by severity or complexity. The largest proportion of HAP guidelines based classification on severity/complexity (nâ=â69/119, 58%). By contrast, definitions in CAP guidelines were uniform. Conclusions: The high heterogeneity in HAP classification identified suggests inconsistency of practice in identifying thresholds for HAP in the UK. This complicates HAP management and AMS practices. To address HAP in alignment with AMS principles, a comprehensive strategy that prioritizes uniform clinical definitions and thresholds should be developed.
RESUMEN
Self-injurious behavior (SIB) among children and youth with developmental disabilities has not diminished in prevalence despite the availability of effective interventions, and the impact on quality of life for people and their families is devastating. The current meta-analysis reviews SIB intervention research between 2011 and 2021 using single-case experimental designs with children and youth up to 21 years old and provides a quantitative synthesis of data from high-quality studies including moderator analyses to determine effects of participant and study characteristics on intervention outcomes. Encouraging findings include a high level of effectiveness across studies in the decrease of SIB (Tau-U = -0.90) and increase of positive behavior (Tau-U = 0.73), as well as an increase in studies (relative to prior reviews) reporting intervention fidelity, generalization, maintenance, and social validity. However, our findings shed limited light on potential moderating variables in the development of interventions for children and youth who exhibit SIB. Of the potential moderators of intervention effects, only implementer (researcher/therapist vs. parent/caregiver) and setting (clinic vs. home) were significantly associated with improved outcomes. We discuss the need for more robust involvement of natural communities of implementers in SIB intervention research to better equip them to effectively and sustainably meet the needs of people they care for. We also discuss the importance of creating systems enabling broad access for children with SIB to effective interventions in service of reducing burden for people, families, and society over time.

Pea phytoalexins (-)-maackiain and (+)-pisatin have opposite C6a/C11a configurations, but biosynthetically how this occurs is unknown. Pea dirigent-protein (DP) PsPTS2 generates 7,2'-dihydroxy-4',5'-methylenedioxyisoflav-3-ene (DMDIF), and stereoselectivity toward four possible 7,2'-dihydroxy-4',5'-methylenedioxyisoflavan-4-ol (DMDI) stereoisomers was investigated. Stereoisomer configurations were determined using NMR spectroscopy, electronic circular dichroism, and molecular orbital analyses. PsPTS2 efficiently converted cis-(3R,4R)-DMDI into DMDIF 20-fold faster than the trans-(3R,4S)-isomer. The 4R-configured substrate's near ß-axial OH orientation significantly enhanced its leaving group abilities in generating A-ring mono-quinone methide (QM), whereas 4S-isomer's α-equatorial-OH was a poorer leaving group. Docking simulations indicated that the 4R-configured ß-axial OH was closest to Asp51, whereas 4S-isomer's α-equatorial OH was further away. Neither cis-(3S,4S)- nor trans-(3S,4R)-DMDIs were substrates, even with the former having C3/C4 stereochemistry as in (+)-pisatin. PsPTS2 used cis-(3R,4R)-7,2'-dihydroxy-4'-methoxyisoflavan-4-ol [cis-(3R,4R)-DMI] and C3/C4 stereoisomers to give 2',7-dihydroxy-4'-methoxyisoflav-3-ene (DMIF). DP homologs may exist in licorice (Glycyrrhiza pallidiflora) and tree legume Bolusanthus speciosus, as DMIF occurs in both species. PsPTS1 utilized cis-(3R,4R)-DMDI to give (-)-maackiain 2200-fold more efficiently than with cis-(3R,4R)-DMI to give (-)-medicarpin. PsPTS1 also slowly converted trans-(3S,4R)-DMDI into (+)-maackiain, reflecting the better 4R configured OH leaving group. PsPTS2 and PsPTS1 provisionally provide the means to enable differing C6a and C11a configurations in (+)-pisatin and (-)-maackiain, via identical DP-engendered mono-QM bound intermediate generation, which PsPTS2 either re-aromatizes to give DMDIF or PsPTS1 intramolecularly cyclizes to afford (-)-maackiain. Substrate docking simulations using PsPTS2 and PsPTS1 indicate cis-(3R,4R)-DMDI binds in the anti-configuration in PsPTS2 to afford DMDIF, and the syn-configuration in PsPTS1 to give maackiain.

BACKGROUND: Globally, detections of carbapenemase-producing Enterobacterales (CPE) colonisations and infections are increasing. The spread of these highly resistant bacteria poses a serious threat to public health. However, understanding of CPE transmission and evidence on effectiveness of control measures is severely lacking. This paper provides evidence to inform effective admission screening protocols, which could be important in controlling nosocomial CPE transmission. METHODS: CPE transmission within an English hospital setting was simulated with a data-driven individual-based mathematical model. This model was used to evaluate the ability of the 2016 England CPE screening recommendations, and of potential alternative protocols, to identify patients with CPE-colonisation on admission (including those colonised during previous stays or from elsewhere). The model included nosocomial transmission from colonised and infected patients, as well as environmental contamination. Model parameters were estimated using primary data where possible, including estimation of transmission using detailed epidemiological data within a Bayesian framework. Separate models were parameterised to represent hospitals in English areas with low and high CPE risk (based on prevalence). RESULTS: The proportion of truly colonised admissions which met the 2016 screening criteria was 43% in low-prevalence and 54% in high-prevalence areas respectively. Selection of CPE carriers for screening was improved in low-prevalence areas by adding readmission as a screening criterion, which doubled how many colonised admissions were selected. A minority of CPE carriers were confirmed as CPE positive during their hospital stay (10 and 14% in low- and high-prevalence areas); switching to a faster screening test pathway with a single-swab test (rather than three swab regimen) increased the overall positive predictive value with negligible reduction in negative predictive value. CONCLUSIONS: Using a novel within-hospital CPE transmission model, this study assesses CPE admission screening protocols, across the range of CPE prevalence observed in England. It identifies protocol changes-adding readmissions to screening criteria and a single-swab test pathway-which could detect similar numbers of CPE carriers (or twice as many in low CPE prevalence areas), but faster, and hence with lower demand on pre-emptive infection-control resources. Study findings can inform interventions to control this emerging threat, although further work is required to understand within-hospital transmission sources.

Background: The responsible use of existing antimicrobials is essential in reducing the threat posed by antimicrobial resistance (AMR). With the introduction of restrictions during the COVID-19 pandemic, a substantial reduction in face-to-face appointments in general practice was observed. To understand if this shift in healthcare provision has impacted on prescribing practices, we investigated antibiotic prescribing for upper respiratory tract infections (URTI) consultations. Methods: We conducted an interrupted time-series analysis using patient-level primary care data to assess the impact of the COVID-19 pandemic on consultations and antibiotic prescribing for URTI in England. Results: We estimated an increase of 105.7 antibiotic items per 1000 URTI consultations (95% CI: 65.6-145.8; Pâ<â0.001) after national lockdown measures in March 2020, with increases mostly sustained to May 2022. Conclusions: Overuse of antibiotics is known to be a driver of resistance and it is essential that efforts to reduce inappropriate prescribing continue subsequent to the COVID-19 pandemic. Further work should examine drivers of increased antibiotic prescribing for URTI to inform the development of targeted antibiotic stewardship interventions.
RESUMEN
CONTEXT: Non-communicable diseases (NCDs), associated with health-related suffering, can benefit from palliative care in resource-limited settings, where over four-fifths of these deaths occur. OBJECTIVE: To measure the prevalence of depressive symptoms, palliative care-related concerns, physical and other psychological symptoms among adult patients with NCDs in Malawi and Namibia. METHODS: This multi-center, cross-sectional study consecutively recruited outpatients from four tertiary referral hospitals. Stepwise regression analysis was used to assess factors associated with physical and psychological symptom burden. RESULTS: Among 457 participants, primary diagnosis was cancer (n=147, 32%); cardiovascular disease (CVD) (n=130, 28%), chronic respiratory disease (CRESD) (n=73, 16%) or diabetes (n=107, 23%). Over half were female (58.9%; n=269), mean age was 48 (SD=15.7). Clinically significant psychological distress was identified among cancer (57.2%), diabetes (57.0%), CRESD (45.2%) and CVD patients (43.1%), with criterion for major depression symptoms met for cancer (42.9%), diabetes (39.2%), CVD (30.0%) and CRESD (28.8%). Most severe palliative care concerns were: first sharing feelings (i.e., not at all/not very often), reported by CVD (28%), CRESD (23%), cancer (22%) and diabetes (21%) patients; second help and advice (i.e., none/very little), among cancer (28%), CVD (26%), diabetes (22%), and CRESD (16%) patients. High prevalence of moderate-to-severe pain was reported (cancer 54%, CVD 41%, CRESD 38%, diabetes 38%). Functional status, age, and presence of comorbidities were associated with physical and psychological symptom distress. CONCLUSION: Given the high burden of physical and psychosocial symptoms and symptom distress, the findings highlight the need for integrated person-centered palliative care for NCDs to optimize care outcomes.

BACKGROUND: Self-directed supports (SDS) are a model of disability service delivery that focuses on supporting increased decision-making authority and budget autonomy for people with disabilities and their families. This study identifies supervisory and administrative staff's perspectives within a self-directed, individualised budgeting programme for people with intellectual and developmental disabilities. METHOD: Data were collected through 28 face-to-face interviews with supervisory and fiscal administrative staff in Minnesota, USA. RESULTS: A qualitative analysis of these interviews resulted in four major themes: (1) the benefits of SDS, (2) the relationship between SDS and person-centred strategies, (3) the perception that a natural tension arises when balancing person-centred approaches with the need for consistent and fair state policy-including rules and regulations within state systems and (4) the unique challenges related to SDS benefits and challenges occurring across Minnesota. CONCLUSIONS: The results indicate the importance of providing effective communication and training to all stakeholders.

Namibia has had three outbreaks of Hepatitis E Virus (HEV), in 1983, 1995 and 2017. HEV is particularly dangerous to pregnant women. The objective of this study was to present a thorough review of the history of HEV in Namibia; the genotypes which have appeared since 1983, and the possible reasons for the nationwide spread of HEV that has occurred since 2017. MATERIALS AND METHODS As this is a review article, no primary research data will be presented. However, an exhaustive literature study has been undertaken and there will be in-depth discussion of the findings of primary researchers in Namibia and elsewhere. RESULTS The first two episodes were confined to the Rundu area. The 1983 outbreak may have been genotype 1; that of 1995 contained genotypes 1 and 2. The genotype of 2017 episode has not been clearly established. Increased road traffic may have spread HEV during 2017-2020. Lack of clean water and washing facilities, and lack of awareness of what causes HEV, are the main factors in spreading it. CONCLUSIONS AND RECOMMENDATIONS There remain challenges to the containment of HEV. A recent government initiative to stop COVID-19 has helped slow its progress. Both infections are propagated by poor hygienic practice and lack of clean water.

Prediabetes has a high prevalence, with early detection essential to facilitate optimal management to prevent the development of conditions such as type 2 diabetes and cardiovascular disease. Prediabetes can include impaired fasting glucose, impaired glucose tolerance and elevated HbA1c. This position statement outlines the approaches to screening and management of prediabetes in primary care. There is good evidence to implement intensive, structured lifestyle interventions for individuals with impaired glucose tolerance. The evidence for those with impaired fasting glucose or elevated HbA1c is less clear, but individuals should still be provided with generalised healthy lifestyle strategies. A multidisciplinary approach is recommended to implement healthy lifestyle changes through education, nutrition and physical activity. Individuals should aim to lose weight (5-10% of body mass) using realistic and sustainable dietary approaches supported by an accredited practising dietitian, where possible. Physical activity and exercise should be used to facilitate weight maintenance and reduce blood glucose. Moderate-vigorous intensity aerobic exercise and resistance training should be prescribed by an accredited exercise physiologist, where possible. When indicated, pharmacotherapy, metabolic surgery and psychosocial care should be considered, in order to enhance the outcomes associated with lifestyle change. Individuals with prediabetes should generally be evaluated annually for their diabetes status.

BACKGROUND: In response to increasing numbers of carbapenemase-producing Enterobacterales (CPE) in England, Public Health England (PHE) launched an electronic reporting system (ERS) for the enhanced surveillance of carbapenemase-producing Gram-negative bacteria. Our study aimed to describe system engagement and the epidemiology of CPE in England. METHODS: Engagement with the ERS was assessed by calculating the proportion of referrals submitted this system. ERS data were extracted and cases defined as patients with CPE isolated from a screening or clinical specimen in England between 1st May 2015 to 31st March 2019. Descriptive summary statistics for each variable were prepared. RESULTS: The ERS processed 12,656 suspected CPE reports. Uptake of the ERS by local microbiology laboratories varied, with approximately 70% of referrals made via the ERS by April 2016; this steadily decreased after March 2018. Six-thousand eight-hundred and fifty-seven cases were included in the analysis. Most cases were from colonised patients (80.6%) rather than infected, and the majority were inpatients in acute hospital settings (87.3%). Carbapenemases were most frequently detected in Klebsiella pneumoniae (39.1%) and Escherichia coli (30.3%). The most frequently identified carbapenemase families were OXA-48-like (45.1%) and KPC (26.4%). Enhanced data variables were poorly completed. CONCLUSIONS: The ERS has provided some insight into the epidemiology of CPE in England. An increasing number of routine diagnostic laboratories have introduced methods to routinely identify acquired carbapenemases and PHE has modified its approach to ensure robust surveillance, which is an essential aspect of an effective response to prevent and control the spread of CPE.
RESUMEN
Test and Rapid Response Treatment (TRRT) linkage programs have demonstrated improved HIV suppression rates. This paper describes the design and implementation of the Miami TRRT initiative and its clinical impact. Assisted by a dedicated care navigator, patients receiving a reactive HIV rapid test at the Florida Department of Health STD Clinic were offered same-day HIV care at the University of Miami/Jackson Memorial Medical Center Adult HIV Outpatient Clinic. Patient retention and labs were tracked for 12 months. Of the 2337 individuals tested, 46 had a reactive HIV test; 41 (89%) consented to participate. For the 36 patients in continued care for a year, 33 (91.7%) achieved virological suppression (< 200 copies/mL) within 70 days of their reactive HIV rapid test; at 12 months, 35 (97.2%) remained suppressed, and mean CD4 T cell counts increased from 452 ± 266 to 597 ± 322 cells/mm3. The Miami TRRT initiative demonstrated that immediate linkage to care is feasible and improves retention and suppression in a public/academic medical center in the U.S. South.

Positive Behavior Support (PBS) was introduced to community-based providers in Kansas in 2012 in response to a federally funded initiative to reduce the placement of youth in psychiatric facilities. As core project activities concluded in 2016, researchers investigated the impact of this comprehensive PBS initiative on youth, families, mental health centers, and other stakeholders. This paper describes how qualitative interviews and focus groups were used to investigate the perceptions of families, advocates, and implementers involved in wraparound (WA), regional interagency collaboration, and the addition of PBS services. Themes reflected the changes occurring over time in statewide WA implementation and how state funding for the PBS effort was used as part of regional interagency collaboration to continue supporting principles outlined in systems of care.

Quantum key distribution (QKD) can be used to produce a cryptographic key whose security is guaranteed by quantum mechanics. The range of fiber-based QKD links is limited, by loss, to a few hundred kilometers, and cannot be used between mobile platforms. Free space QKD can, in principle, overcome these limitations. In practice, very narrow beam divergences must be used, requiring highly accurate pointing of the transmitting terminal to the receiver. This makes deployment very difficult. Here we describe the experimental implementation of a new type of free space QKD link, using modulating retro-reflectors (MRR). The MRR-QKD link eases the pointing requirements by more than three orders of magnitude, from microradians to degrees, while maintaining the narrow beam divergence necessary for long-range communication links. The system uses new, high extinction surface-normal multiple quantum well modulators with a modulation rate of 100 MHz. A laboratory-based BB84 QKD link using multiple quantum well MRRs is demonstrated, link budgets for possible applications are discussed, and security issues are considered.
RESUMEN
BACKGROUND: Namibia has one of the highest human immunodeficiency virus (HIV) prevalence rates and one of the highest rates of orphanhood in the world, and older caregivers provide much of the care to Namibians living with HIV and acquired immune deficiency syndrome (AIDS) (UNAIDS, 2014). In this study, the authors explore how financial status, social support, and health were related to the resilience of caregivers caring for people affected by HIV and AIDS in rural northern Namibia, Africa. METHOD: Data were collected through a structured interview from (N = 147) caregivers from the Zambezi region. RESULTS: Findings from this study show that employment and physical health were significantly associated with increased resilience in older caregivers. DISCUSSION: Our findings point to the need for employment assistance and health services to improve the resilience of caregivers caring for people living with HIV and AIDS. We conclude that there is a need for more vigorous concerted efforts from public and private sector practitioners and policy makers to create more sustained formal employment opportunities and intervention programs aimed at improving the overall health of older HIV caregivers, especially those residing in rural HIV endemic communities in developing countries.

Objectives: To evaluate the association between use of different antibiotics and trimethoprim resistance at the population level. Methods: Monthly primary care prescribing data were obtained from NHS Digital. Positive Enterobacteriaceae records from urine samples from patients between April 2014 and January 2016 in England were extracted from PHE's Second Generation Surveillance System (SGSS). Elastic net regularization and generalized boosted regression models were used to evaluate associations between antibiotic prescribing and trimethoprim resistance, both measured at Clinical Commission Group level. Results: In total, 2â¯487â¯635 (99%) of 2â¯513â¯285 urine Enterobacteriaceae samples from 1â¯667â¯839 patients were tested for trimethoprim resistance. Using both elastic net regularization and generalized boosted regression models, geographical variation in trimethoprim resistance among Enterobacteriaceae urinary samples could be partly explained by geographical variation in use of trimethoprim (relative risk = 1.14, 95% CI = 1.02-1.75; relative influence = 4.1) and penicillins with extended spectrum (mainly amoxicillin/ampicillin in England) (relative risk = 1.19, 95% CI = 1.11-1.30; relative influence = 7.4). Nitrofurantoin use was associated with lower trimethoprim resistance levels (relative risk = 0.83, 95% CI = 0.57-0.96; relative influence = 9.2). Conclusions: Use of amoxicillin/ampicillin explained more of the variance in trimethoprim resistance than trimethoprim use, suggesting that co-selection by these antibiotics is an important driver of trimethoprim resistance levels at the population level. Nitrofurantoin use was consistently associated with lower trimethoprim resistance levels, indicating that trimethoprim resistance levels could be lowered if trimethoprim use is replaced by nitrofurantoin.

Childhood sexual abuse (CSA) is highly prevalent and associated with a wide variety of negative mental and physical health outcomes. School-based CSA education and prevention programs have shown promise, but it is unclear to what extent community-level characteristics are related to their effectiveness. The present cluster randomized controlled trial evaluated community-level moderators of the Safe@Lastprogramcomparedtoawaitlistcontrolcondition.(*) Knowledge gains from pre- to post-intervention were assessed in 5 domains: safe versus unsafe people; safe choices; problem-solving; clear disclosure; and assertiveness. Participants were 1177 students (46% White, 26% African American, 15% Hispanic, 4% Asian American, 6% Other) in grades 1 through 6 from 14 public schools in Tennessee. Multilevel models accounting for the nesting of children within schools revealed large effect sizes for the intervention versus control across all knowledge domains (d's ranged from 1.56 to 2.13). The effectiveness of the program was moderated by mean per capita income and rates of substantiated cases of child abuse and neglect in the community. Intervention effects were stronger for youth living in lower as compared to higher income counties, and for youth attending schools in counties with lower as compared to higher abuse/neglect rates. Child characteristics (sex, race) did not moderate intervention effects. This research identified two community-level factors that predicted the effectiveness of a CSA education and prevention program designed to improve children's knowledge of personal safety skills. School-based CSA prevention programs may require modification for communities with higher rates of child abuse and neglect.

The high burden of non-communicable diseases and communicable diseases in Africa characterised by late presentation and diagnosis makes the need for palliative care a priority from the point of diagnosis to death and through bereavement. Palliative care is an intervention that requires a multidisciplinary team to address the multifaceted needs of the patient and family. Thus, its development takes a broad approach that involves engaging all key stakeholders ranging from policy makers, care providers, educators, the public, patients, and families. The main focus of stakeholder engagement should address some core interventions geared towards improving knowledge and awareness, strengthening skills and attitudes about palliative care. These interventions include educating health and allied healthcare professionals on the palliative care-related problems of patients and best practices for care, explaining palliative care as a clinical and holistic discipline and demonstrating its effectiveness, the need to include palliative care into national policies, strategic plans, training curriculums of healthcare professionals and the engagement of patients, families, and communities. Interventions from a five-year programme that was aimed at strengthening the health system of Namibia through the integration of palliative care for people living with HIV and AIDS and cancer in Namibia are shared. This article illustrates how a country can implement the World Health Organisation's public health strategy for developing palliative care services, which recommends four pillars: government policy, education, drug availability, and implementation.
RESUMEN
OBJECTIVES: We examined the 4 year trend in antimicrobial susceptibilities and prescribing across levels of care at two London teaching hospitals and their multisite renal unit, and for the surrounding community. METHODS: Laboratory and pharmacy information management systems were interrogated, with antimicrobial use and susceptibilities analysed between hospitals, within hospitals and over time. RESULTS: A total of 108,717 isolates from 71,687 patients were identified, with significant differences (at P < 0.05) in antimicrobial susceptibility between and within hospitals. Across the 4 years, rates of ESBL-/AmpC-producing Enterobacteriaceae ranged from 6.4% to 10.7% among community isolates, 17.8% to 26.9% at ward level and 25.2% to 52.5% in critical care. Significant variations were also demonstrated in glycopeptide-resistant enterococci (ward level 6.2%-17.4%; critical care 21.9%-56.3%), MRSA (ward level 18.5%-38.2%; critical care 12.5%-47.9%) and carbapenem-resistant Pseudomonas spp. (ward level 8.3%-16.9%; critical care 19.9%-53.7%). Few instances of persistently higher resistance were seen between the hospitals in equivalent cohorts, despite persistently higher antimicrobial use in Hospital 1 than Hospital 2. We found significant fluctuations in non-susceptibility year on year across the cohorts, but with few persistent trends. CONCLUSIONS: The marked heterogeneity of antimicrobial susceptibilities between hospitals, within hospitals and over time demands detailed, standardized surveillance and appropriate benchmarking to identify possible drivers and effective interventions. Homogeneous antimicrobial policies are unlikely to continue to be suitable as individual hospitals join hospital networks, and policies should be tailored to local resistance rates, at least at the hospital level, and possibly with finer resolution, particularly for critical care.

An accurate characterisation of the organic dyes used in artworks, especially those made of paper, is an important factor in designing safe conservation treatments. In the case of synthetic organic dyes used in modern works of art, for example, one frequently encountered difficulty is that some of these dyes are not still commercially available. Recognizing this problem, the authors of this paper present the results of an analysis of UV-Vis-NIR fibre optic reflectance spectra of 82 samples of dyed paper prepared with 41 dyes. The samples come from a historic book, The Dyeing of Paper in the Pulp, which was published by Interessen-Gemeinschaft (I.G.) Farbenindustrie in 1925. The dyes used in the paper pulp belong to the azo compounds, acridine, anthraquinone, azine, diphenylmethane, indigoid, methine, nitro, quinoline, thiazine, triphenylmethane, sulphur and xanthene classes.
