Too much ado about data: Continuous remote monitoring of water temperatures, circulation and throughput can assist in the reduction of hospital-associated waterborne infections.

BACKGROUND: National and international guidance provides advice on maintenance and management of water systems in healthcare buildings, however, healthcare-associated waterborne infections (HAWI) are increasing. This narrative review identifies parameters critical to water quality in healthcare buildings and assesses if remote sensor monitoring can deliver safe water systems thus reducing HAWI. METHOD: A narrative review was performed using the following search terms 1) consistent water temperature AND waterborne pathogen control OR nosocomial infection 2) water throughput AND waterborne pathogen control OR nosocomial infection 3) remote monitoring of in-premise water systems AND continuous surveillance for temperature OR throughput OR flow OR use. Databases employed were PubMed, CDSR (Clinical Study Data Request) and DARE (Database of Abstracts of Reviews of Effects) from Jan 2013 - Mar 2024. FINDINGS: Single ensuite-patient rooms, expansion of wash-hand basins, widespread glove use, alcohol gel and wipes have increased water system stagnancy resulting in amplification of waterborne pathogens and transmission risk of Legionella, Pseudomonas and Non-Tuberculous Mycobacteria. Manual monitoring does not represent temperatures across large complex water systems. This review deems that multiple point continuous remote sensor monitoring is effective at identifying redundant and low use outlets, hydraulic imbalance and inconsistent temperature delivery across in-premise water systems. CONCLUSION: As remote monitoring becomes more common there will be greater recognition of failures in temperature control, hydraulics and balancing in water systems and there remains much to learn as we adopt this developing technology within our hospitals.

Water free patient care, a narrative review of the literature and discussion of the pressing need for a way forward.

BACKGROUND: Florence Nightingale was the first person to recognise the link between the built environment and patient ill-health. More than 160 years later the threat of the end of the antibiotic era looms large. The AMR action plan focuses on antimicrobial stewardship and developing new therapeutic agents. The risk from the built environment has been ignored, with wastewater systems identified as major sources of antimicrobial resistance within healthcare facilities. England is undertaking the largest healthcare construction programmes globally. These facilities will be operating when antimicrobial resistance is predicted to be at its fiercest. Water free patient care is a strategy for limiting dispersal of antimicrobial resistance and preventing patient infections that need further evaluation in new hospitals. METHOD: A narrative review was undertaken using terms; waterless/waterfree units, waterless/waterfree care, sink reduction, sink removal, washing without water. Databases employed were Pubmed, CDSR,and DARE from January 2000- February 2024 for reviews and original articles. Unit type, geographical location, reasons for a waterless/waterfree approach and outcomes were recorded. FINDINGS: Seven papers were identified. Four involved adult intensive care units (ICU), one from care of the elderly settings and two involved a neonatal ICU (NICU). In five papers the aim of intervention was to reduce Gram-negative infections/colonisations. One paper was a systematic review of 'washing without water' which reviewed cost effectiveness and patient experience Of the five papers focusing on Gram-negative bacilli (GNB) all reported a reduction in infections or colonisations post intervention. CONCLUSION: More studies are highlighting the risks from water and wastewater to patient safety and the value of "waterfree" strategies in reducing infection rates.

The impact of gastroesophageal reflux disease and its treatment on interstitial lung disease outcomes.

BACKGROUND: To determine the relationship between gastroesophageal reflux disease (GORD) and its treatment and interstitial lung disease in patients with systemic sclerosis (SSc). METHODS: SSc patients from the Australian Scleroderma Cohort Study (ASCS) were included. GORD was defined as self-reported GORD symptoms, therapy with a proton pump inhibitor (PPI) or histamine 2 receptor antagonist (H2RA) and/or the presence of reflux oesophagitis diagnosed endoscopically. The impact of GORD and its treatment on ILD features (including severity and time to ILD development) and survival was evaluated. RESULTS: GORD was a common manifestation affecting 1539/1632 (94%) of SSc patients. GORD affected 450/469 (96%) of those with SSc-ILD cohort. In SSc-ILD, there was no relationship between the presence of GORD or its treatment and time to ILD development or ILD severity. However, GORD treatment was associated with improved survival in those with ILD (p = 0.002). Combination therapy with both a PPI and a H2RA was associated with a greater survival benefit than single agent therapy with PPI alone (HR 0.3 vs 0.5 p < 0.050 respectively). CONCLUSION: GORD is a common SSc disease manifestation. While the presence or treatment of GORD does not influence the development or severity of ILD, aggressive GORD treatment, in particular with a combination of PPI and H2RA, is associated with improved survival in those with SSc-ILD.

Synthesis of ionizable lipopolymers using split-Ugi reaction for pulmonary delivery of various size RNAs and gene editing.

We present an efficient approach for synthesizing cationic poly(ethylene imine) derivatives using the multicomponent split-Ugi reaction to rapidly create a library of complex functional ionizable lipopolymers. We synthesized a diverse library of 155 polymers, formulated them into polyplexes to establish structure-activity relationships crucial for endosomal escape and efficient transfection. After discovering a lead structure, lipopolymer-lipid hybrid nanoparticles are introduced to preferentially deliver to and elicit effective mRNA transfection in lung endothelium and immune cells, including T cells with low in vivo toxicity. The lipopolymer-lipid hybrid nanoparticles showed 300-fold improvement in systemic mRNA delivery to the lung compared to in vivo -JetPEI ® . Lipopolymer-lipid hybrid nanoparticles demonstrated efficient delivery of mRNA-based therapeutics for treatment of two different disease models. Lewis Lung cancer progression was significantly delayed after treatment with loaded IL-12 mRNA in U155@lipids after repeated i.v. administration. Systemic delivery of human CFTR (hCFTR) mRNA resulted in production of functional form of CFTR protein in the lungs. The functionality of hCFTR protein was confirmed by restoration of CFTR- mediated chloride secretion in conductive airway epithelia in CFTR knockout mice after nasal instillation of hCFTR mRNA loaded U155@lipids. We further showed that, U155@lipids nanoparticles can deliver complex CRISPR-Cas9 based RNA cargo to the lung, achieving 5.6 ± 2.4 % gene editing in lung tissue. Moreover, we demonstrated successful PD-1 gene knockout of T cells in vivo . Our results highlight a versatile delivery platform for systemic delivering of mRNA of various sizes for gene therapy for a variety of therapeutics.

The interaction of genes and environment on percent of juniper in the diet of goats divergently selected for high or low juniper consumption.

Diet selection and preference by grazing animals are determined by genetic and environmental factors that interact and affect their efficacy for managing vegetation as targeted grazers and developing animals adapted to local grazing environments. The effect of the rearing environments on the consumption of juniper (Juniperus spp.) by goats that for 15 years were divergently selected for high (J+) or low (J-) percent juniper in their diet was investigated. To test the effect of rearing environment, at the end of the breeding season, pregnant does from both selection lines were grazed on either juniper-infested (JIR) or juniper-free (JFR) rangelands until their kids were weaned at about 75 days of age. Fecal samples were analyzed with fecal near-IR spectroscopy to determine the percent juniper in the diet. Fecal samples were collected from does on JIR when their offspring were 30 days of age and at weaning. Then, does that raised kids in both rearing environments grazed a common JIR pasture for a 28-day adaptation period before collecting fecal samples. After weaning, kids from both rearing environments grazed JIR for 22 days before collecting fecal samples. The J+ does always consumed more (P < 0.001) juniper than J- does, demonstrating different maternal role models for kids reared in the JIR environment. There was no effect of rearing environment (P = 0.488) or rearing environment × selection line interaction (P = 0.096) when J- and J+ does grazed a common JIR pasture. The percentage of juniper in J- kid diets (7%) was the same regardless of the rearing environment. However, the rearing environment did affect the percentage of juniper in the diet of J+ kids, resulting in a gene-environment interaction (P = 0.022). The percentage of juniper in the diet of J+ kids reared in JFR (16%) and JIR (24%) were about two and three times higher than J- kids, respectively, indicating that genetics and the rearing environment contributed about equally to the increase in the percentage of juniper in the J+ kid diets. Regardless of the rearing environment, the J+ kids had a higher percentage of juniper in their diets than J- kids (P < 0.001). Compared to males, female kids had a higher percentage of juniper in their diets (12 vs 17%, respectively; P = 0.002). The ability to select animals with specific dietary preferences holds promise for targeted grazing strategies to restore degraded rangelands, with potential applications in conservation and ecosystem management.

Community (dis)connectedness and identity among LGBTQIA+ people during the COVID-19 pandemic: A qualitative cross-sectional and longitudinal trajectory study.

The coronavirus disease 2019 (COVID-19) pandemic and associated shelter-in-place ordinances passed in the first year of the pandemic rapidly limited access to in-person social interactions, raising concerns of diminishing social support and community cohesion while psychological stressors increased. For LGBTQIA+ people, connectedness to the LGBTQIA+ community is known to buffer against the harmful effects of stressors and decrease risks for poor psychological and behavioral health outcomes. The current study uses qualitative cross-sectional and trajectory analysis methods to characterize how LGBTQIA+ people's perceptions of community connectedness shifted during the first year of the pandemic. A convenience sample of LGBTQIA+-identified people in the U.S. completed an initial online survey in September 2020 (n = 298 and a follow-up survey in September 2021 (n = 129). The survey included changes in connectedness to the LGBTQIA+ community since the pandemic's beginning. Thus, we used both cross-sectional (between-person analyses) and longitudinal trajectory (within-person analyses) qualitative approaches to understanding changes in LGBTQIA+ people's sense of connection to the LGBTQIA+ community across the first two years of the COVID-19 pandemic. Eight cross-cutting themes (related to identity shifts/exploration, disconnection, online connections, and increased awareness of social justice issues) were identified and then organized within each level of the Social-Ecological Model of LGBTQIA+ wellbeing (i.e., the individual-, couple-, interpersonal-, organizational-, community-, and chronosystem- level). Given the importance of social support for LGBTQIA+ wellbeing, more longitudinal research is needed to determine whether these changes persist after the resolution of the acute phase of the pandemic.

Assessment of Ventilation Using Adult and Pediatric Manual Resuscitators in a Simulated Adult Patient.

BACKGROUND: The bag-valve-mask (BVM) or manual resuscitator bag is used as a first-line technique to ventilate patients with respiratory failure. Volume-restricted manual resuscitator bags (eg, pediatric bags) have been suggested to minimize overventilation and associated complications. There are studies that both support and caution against the use of a pediatric resuscitator bag to ventilate an adult patient. In this study, we evaluated the ability of pre-hospital clinicians to adequately ventilate an adult manikin with both an adult- and pediatric-size manual resuscitator bag without the assistance of an advanced airway or airway adjunct device. METHODS: This study was conducted at an international conference in 2022. Conference attendees with pre-hospital health care experience were recruited to ventilate an adult manikin using a BVM for 1 min with both an adult and pediatric resuscitator bag, without the use of adjunct airway devices, while 6 ventilatory variables were collected or calculated: tidal volume (VT), breathing frequency, adequate breaths (VT > 150 mL), proportion of adequate breaths, peak inspiratory pressure (PIP), and estimated alveolar ventilation (EAV). RESULTS: A total of 208 participants completed the study. Ventilation with the adult-sized BVM delivered an average VT of 290.4 mL compared to 197.1 mL (P < .001) when using the pediatric BVM. PIP with the adult BVM was higher than with the pediatric BVM (10.6 cm H2O vs 8.6 cm H2O, P < .001). The median EAV with the adult bag (1,138.1 [interquartile range [IQR] 194.0-2,869.9] mL/min) was markedly greater than with the pediatric BVM (67.7 [IQR 0-467.3] mL/min, P < .001). CONCLUSIONS: Both pediatric- and adult-sized BVM provided lower ventilation volumes than those recommended by professional guidelines for an adult. Ventilation with the pediatric BVM was significantly worse than with the adult bag when ventilating a simulated adult subject.

Spontaneously Sliding Multipole Spin Density Waves in Cold Atoms.

We report on the observation of spontaneously drifting coupled spin and quadrupolar density waves in the ground state of laser driven Rubidium atoms. These laser-cooled atomic ensembles exhibit spontaneous magnetism via light mediated interactions when submitted to optical feedback by a retroreflecting mirror. Drift direction and chirality of the waves arise from spontaneous symmetry breaking. The observations demonstrate a novel transport process in out-of-equilibrium magnetic systems.

Asynchronous lecture participation negatively predicts exam scores for females and students of color in an introductory physiology course during COVID-19.

In response to COVID-19, educators rapidly pivoted to new and innovative ways of delivering lecture material. The ability to host synchronous lectures on platforms like Zoom gave students continued access to classroom material in the face of an ongoing pandemic. The purpose of this study was to investigate the differences in exam scores between students attending a physiology class (PHSL3051) synchronously via Zoom or asynchronously by viewing recorded lectures posted after class. Students in PHSL3051 were evaluated with four unit exams and one cumulative final exam. Although pooled analysis of all students showed that synchronous lecture viewing positively predicted exam scores, this positive association was even larger when the data were analyzed by gender and ethnicity. For female-identified students and students of color (SOC), attending lectures synchronously was associated with average scores on every unit exam that were higher by 2.7-7.4 percentage points. Moreover, the greater a student's synchronous participation in the course throughout the semester, the better that student's performance on the cumulative final exam was likely to be. These data highlight the need to better understand how different groups of undergraduate students select and respond to different assessment methods used in the same course, which may have long-term effects on their overall performance at 4-year institutions.NEW & NOTEWORTHY This study examined the relationship between lecture attendance (synchronous or asynchronous) and exam scores throughout the semester. Although everyone in the course benefited from synchronous lecture attendance, our data indicated that students of color (SOC) and female-identified students benefited most. SOC and female-identified students who participated synchronously had even higher mean scores on all exams within the course compared with SOC and female-identified students who participated asynchronously by watching recordings of the same lectures.

Animal movement on the hoof and on the cart and its implications for understanding exchange within the Indus Civilisation.

Movement of resources was essential to the survival and success of early complex societies. The sources and destinations of goods and the means of transportation - be it by boats, carts and/or foot - can often be inferred, but the logistics of these movements are inherently more difficult to ascertain. Here, we use strontium isotopic analysis to test hypotheses about the role of animal and animal-powered transport in medium and long-distance movement and exchange, using the Indus Civilization as a case study. Across the wide geographical spread of the Indus Civilisation, there is strong evidence for long-distance exchange of raw materials and finished objects and this process is presumed to involve boats and animal-driven transport, although there is little evidence as to the relative importance of each mode of movement. Strontium isotopic analysis of animal remains from four sites analysed for this study combined with results from nine other sites indicates limited long-distance animal movement between different geological zones within the Indus Civilisation. These findings suggest that individual animals primarily moved short- or medium-distances, though there are several significant exceptions seen in some pigs and cattle found at two large urban sites. We infer that long-distance transport of goods, be it raw materials, finished objects, other goods, or the animals themselves, could have occurred through the use of boats and waterways, by traction animals moving over long distances that did not end up in the archaeological record, and/or by different animals participating in many short to medium-distance movements.

ICD-10 diagnosis codes in electronic health records do not adequately capture fracture complexity for proximal humerus fractures.

BACKGROUND: The ability to do comparative effectiveness research (CER) for proximal humerus fractures (PHF) using data in electronic health record (EHR) systems and administrative claims databases was enhanced by the 10th revision of the International Classification of Diseases (ICD-10), which expanded the diagnosis codes for PHF to describe fracture complexity including displacement and the number of fracture parts. However, these expanded codes only enhance secondary use of data for research if the codes selected and recorded correctly reflect the fracture complexity. The objective of this project was to assess the accuracy of ICD-10 diagnosis codes documented during routine clinical practice for secondary use of EHR data. METHODS: A sample of patients with PHFs treated by orthopedic providers across a large, regional health care system between January 1, 2016, and December 31, 2018, were retrospectively identified from the EHR. Four fellowship-trained orthopedic surgeons reviewed patient radiographs and recorded the Neer Classification characteristics of displacement, number of parts, and fracture location(s). The fracture characteristics were then reviewed by a trained coder, and the most clinically appropriate ICD-10 diagnosis code based on the number of fracture parts was assigned. We assessed congruence between ICD-10 codes documented in the EHR and radiograph-validated codes, and assessed sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for EHR-documented ICD-10 codes. RESULTS: There were 761 patients with unilateral, closed PHF who met study inclusion criteria. On average, patients were 67 years of age and 77% were female. Based on radiograph review, 37% were 1-part fractures, 42% were 2-part, 11% were 3-part, and 10% were 4-part fractures. Of the EHR diagnosis codes recorded during clinical practice, 59% were "unspecified" fracture diagnosis codes that did not identify the number of fracture parts. Examination of fracture codes revealed PPV was highest for 1-part (PPV = 0.66, 95% confidence interval [CI] 0.60-0.72) and 4-part fractures (PPV = 0.67, 95% CI 0.13-1.00). CONCLUSIONS: Current diagnosis coding practices do not adequately capture the fracture complexity needed to conduct subgroup analysis for PHF. Conclusions drawn from population studies or large databases using ICD-10 codes for PHF classification should be interpreted within this limitation. Future studies are warranted to improve diagnostic coding to support large observational studies using EHR and administrative claims data.

Deriving early single-rosette brain organoids from human pluripotent stem cells.

Brain organoid methods are complicated by multiple rosette structures and morphological variability. We have developed a human brain organoid technique that generates self-organizing, single-rosette cortical organoids (SOSR-COs) with reproducible size and structure at early timepoints. Rather than patterning a 3-dimensional embryoid body, we initiate brain organoid formation from a 2-dimensional monolayer of human pluripotent stem cells patterned with small molecules into neuroepithelium and differentiated to cells of the developing dorsal cerebral cortex. This approach recapitulates the 2D to 3D developmental transition from neural plate to neural tube. Most monolayer fragments form spheres with a single central lumen. Over time, the SOSR-COs develop appropriate progenitor and cortical laminar cell types as shown by immunocytochemistry and single-cell RNA sequencing. At early time points, this method demonstrates robust structural phenotypes after chemical teratogen exposure or when modeling a genetic neurodevelopmental disorder, and should prove useful for studies of human brain development and disease modeling.

Pandemic politics: Exploring the intersection of state political affiliation and public universities' COVID-19 policies and messaging.

As coronavirus disease 2019 (COVID-19) spread within the United States, the challenge of responding to a large-scale health crisis was compounded as the federal government struggled to deliver a unified response. Decision-making powers for pandemic protocols were passed to individual states, whose responses were heavily influenced by their administrations' partisan political leanings. This study explores differences in the transparency of COVID-19 information on university websites and the restrictiveness of the measures they implemented by examining university messaging in all-Republican and all-Democrat controlled states. This study employs a quantitative content analysis of a census of websites (N = 265) from public universities located in states with government trifectas. The data reveal that masking, vaccination, and testing measures were significantly more restrictive among universities located in Democratic trifectas than in Republican trifectas. Additionally, universities in Democratic trifectas communicated more transparently, such that they were more likely to have a direct link to COVID-19 information on their homepages. The results indicate that universities in states where a single political party holds power implemented COVID-19 protocols that reflected the political -viewpoints on the health and economic responses to the pandemic. This finding offers important evidence that both governments and public universities based their public health decisions on political factors.

Protocol for the Brain Health Support Program Study of the Canadian Therapeutic Platform Trial for Multidomain Interventions to Prevent Dementia (CAN-THUMBS UP): A Prospective 12-Month Intervention Study.

BACKGROUND/OBJECTIVES: CAN-THUMBS UP is designed as a comprehensive and innovative fully remote program to 1) develop an interactive and compelling online Brain Health Support Program intervention, with potential to positively influence dementia literacy, self-efficacy and lifestyle risk factors; 2) enroll and retain a community-dwelling Platform Trial Cohort of individuals at risk of dementia who will participate in the intervention; 3) support an open platform trial to test a variety of multidomain interventions that might further benefit individuals at risk of dementia. This manuscript presents the Brain Health Support Program Study protocol. DESIGN/SETTING: Twelve-month prospective multi-center longitudinal study to evaluate a fully remote web-based educational intervention. Participants will subsequently be part of a Platform Trial Cohort and may be eligible to participate in further dementia prevention clinical trials. PARTICIPANTS: Three hundred fifty older adults who are cognitively unimpaired or have mild cognitive impairment, with at least 1 well established dementia risk factor. INTERVENTION: Participants engage in the Brain Health Support Program intervention for 45-weeks and complete pre/post intervention measures. This intervention is designed to convey best available evidence for dementia prevention, consists of 181 chapters within 8 modules that are progressively delivered, and is available online in English and French. The program has been developed as a collaborative effort by investigators with recognized expertise in the program's content areas, along with input from older-adult citizen advisors. MEASUREMENTS: This study utilizes adapted remote assessments with accessible technologies (e.g. videoconferencing, cognitive testing via computer and mobile phone, wearable devices to track physical activity and sleep, self-administered saliva sample collection). The primary outcome is change in dementia literacy, as measured by the Alzheimer's Disease Knowledge Scale. Secondary outcomes include change in self-efficacy; engagement using the online program; user satisfaction ratings; and evaluation of usability and acceptance. Exploratory outcomes include changes in attitudes toward dementia, modifiable risk factors, performance on the Neuropsychological Test Battery, performance on self-administered online cognitive assessments, and levels of physical activity and sleep; success of the national recruitment plan; and the distribution of age adjusted polygenic hazard scores. CONCLUSIONS: This fully remote study provides an accessible approach to research with all study activities being completed in the participants' home environment. This approach may reduce barriers to participation, provide an easier and less demanding participant experience, and reach a broader geography with recruitment from all regions of Canada. CAN-THUMBS UP represents a Canadian contribution to the global World-Wide FINGERS program (alz.org/wwfingers).

Periodic arrays of structurally complex oxide nanoshells and their use as substrate-confined nanoreactors.

Sacrificial templates present an effective pathway for gaining high-level control over nanoscale reaction products. Atomic layer deposition (ALD) is ideally suited for such approaches due to its ability to replicate the surface topography of a template material through the deposition of an ultrathin conformal layer. Herein, metal nanostructures are demonstrated as sacrificial templates for the formation of architecturally complex and deterministically positioned oxide nanoshells, open-topped nanobowls, vertically standing half-shells, and nanorings. The three-step process sees metal nanocrystals formed in periodic arrays, coated with an ALD-deposited oxide, and hollowed out with a selective etch through nanopores formed in the oxide shell. The procedure is further augmented through the use of a directional ion beam that is used to sculpt the oxide shells into bowl- and ring-like configurations. The functionality of the so-formed materials is demonstrated through their use as substrate-confined nanoreactors able to promote the growth and confinement of nanomaterials. Taken together, the work expands the design space for substrate-based nanomaterials, creates a platform for advancing functional surfaces and devices and, from a broader perspective, advances the use of ALD in forming complex nanomaterials.

Anthracyclines and Biomarkers of Myocardial Injury: The Effect of Remote Ischemic Conditioning.

Background: Remote ischemic conditioning (RIC) has been beneficial in laboratory studies of anthracycline cardiotoxicity, but its effects in patients is not established. Objectives: The authors studied the effect of RIC on cardiac biomarkers and function during and after anthracycline chemotherapy. Methods: The ERIC-Onc study (Effect of Remote Ischaemic Conditioning in Oncology Patients; NCT02471885) was a randomized, single-blind, sham-controlled study of RIC at each chemotherapy cycle. The primary endpoint was troponin T (TnT) during chemotherapy and up to 1 year. Secondary outcomes included cardiac function, major adverse cardiovascular events (MACE), and MACE or cancer death. Cardiac myosin-binding-protein C (cMyC) was investigated in parallel with TnT. Results: The study was prematurely halted after the evaluation of 55 patients (RIC n = 28, sham n = 27). Biomarkers increased from baseline to cycle 6 of chemotherapy for all patients (median TnT 6 [IQR: 4-9] ng/L to 33 [IQR: 16-36)] ng/L; P ≤ 0.001; cMyC 3 (IQR: 2-5) ng/L to 47 (IQR: 18-49) ng/L; P ≤ 0.001). Mixed-effects regression analysis for repeated measures showed no difference in TnT between the 2 groups (RIC vs sham, mean difference 3.15 ng/L; 95% CI: -0.04 to 6.33; P = 0.053), or cMyC (RIC vs sham, mean difference 4.17 ng/L; 95% CI: -0.12 to 8.45; P = 0.056). There were more MACE and cancer deaths in the RIC group (11 vs 3; HR: 0.25; 95% CI: 0.07-0.90; P = 0.034), with more cancer deaths (8 vs 1; HR: 0.21; 95% CI: 0.04-0.95; P = 0.043) at 1 year. Conclusions: TnT and cMyC significantly increased during anthracycline chemotherapy with 81% having a TnT ≥14 ng/L at cycle 6. RIC did not affect the rise in biomarkers, but there was a small increase in early cancer deaths, possibly related to the greater proportion of patients with metastatic disease randomized to the RIC group (54%vs 37%).

Black sexual and gender diverse scholars' contributions to psychology.

Psychology has a long history of perpetuating scientific racism and pathologizing gender and sexually diverse individuals. The field has been criticized for the reproduction of racism, sexism, cissexism, and other social inequities. This intersectional epistemological exclusion has led to a lack of appreciation for the work of Black sexual and gender diverse (SGD) scholars within the field of psychology. To highlight and center the contributions of Black SGD scholars in the field, we conducted an in-depth literature search of the work of 62 Black SGD scholars whose names and curricula vitae were obtained through email listservs, Twitter, and snowball sampling. In analyzing the work of the scholars, a total of 34 Black SGD scholars met inclusion criteria and had their research included in our review. We summarize their major contributions to the field of psychology in this article. Implications of these scholars' works and their potential to help address the lack of visibility of Black SGD scholars in mainstream psychology journals are discussed.

Waterborne infections in haemato-oncology units - a narrative review.

Bone marrow transplant and haemato-oncology patients are at risk of healthcare-associated infections due to waterborne pathogens. We undertook a narrative review of waterborne outbreaks in haemato-oncology patients from 2000 to 2022. Databases searched included PubMed, DARE and CDSR, and were undertaken by two authors. We analysed the organisms implicated, sources identified and infection prevention and control strategies implemented. The most commonly implicated pathogens were Pseudomonas aeruginosa, non-tuberculous mycobacteria and Legionella pneumophila. Bloodstream infection was the most common clinical presentation. The majority of incidents employed multi-modal strategies to achieve control, addressing both the water source and routes of transmission. This review highlights the risk to haemato-oncology patients from waterborne pathogens and discusses future preventative strategies and the requirement for new UK guidance for haemato-oncology units.
