RESUMO

BACKGROUND: When a patient is disabled after stroke, they require both emotional support and medical management and may require the assistance of a caregiver. Given the often-sudden onset of disability and the complex challenges related to caring for someone after stroke, caregivers can experience a heavy burden. Caregiver burden negatively affects quality of care, quality of life, and physical and psychological health. The impact of gender on caregiver burden has been in many other conditions; however, the association has not yet been thoroughly assessed in stroke. OBJECTIVE: The aim of this paper is to define caregiver burden, discuss how it is assessed, discuss unique aspects of burden for stroke caregivers, and determine the impact of sex and gender on stroke caregiver role and burden. METHODS: A narrative review was performed to synthesize the available literature and explore how the role of sex and gender impact caregiving for patients who have suffered stroke and whether sex and gender of the caregiver contribute to caregiver burden r. RESULTS: Review of the available literature suggests that sex and gender significantly impact caregiving burden following stroke dipropionately affecting women. CONCLUSIONS: Caregiving for patients who have suffered stroke is often provided by women both inside the home and when patients are within institutions. Women who serve as caregivers to stroke patients may be at higher risk of experiencing burden and its negative effects, including emotional strain, anxiety, and/or depression. More research is needed to determine the best ways to provide support for women who act as caregivers for stroke patients to mitigate caregiver burden.

RESUMO

Immunological health has been challenging to characterize but could be defined as the absence of immune pathology. While shared features of some immune diseases and the concept of immunologic resilience based on age-independent adaptation to antigenic stimulation have been developed, general metrics of immune health and its utility for assessing clinically healthy individuals remain ill defined. Here we integrated transcriptomics, serum protein, peripheral immune cell frequency and clinical data from 228 patients with 22 monogenic conditions impacting key immunological pathways together with 42 age- and sex-matched healthy controls. Despite the high penetrance of monogenic lesions, differences between individuals in diverse immune parameters tended to dominate over those attributable to disease conditions or medication use. Unsupervised or supervised machine learning independently identified a score that distinguished healthy participants from patients with monogenic diseases, thus suggesting a quantitative immune health metric (IHM). In ten independent datasets, the IHM discriminated healthy from polygenic autoimmune and inflammatory disease states, marked aging in clinically healthy individuals, tracked disease activities and treatment responses in both immunological and nonimmunological diseases, and predicted age-dependent antibody responses to immunizations with different vaccines. This discriminatory power goes beyond that of the classical inflammatory biomarkers C-reactive protein and interleukin-6. Thus, deviations from health in diverse conditions, including aging, have shared systemic immune consequences, and we provide a web platform for calculating the IHM for other datasets, which could empower precision medicine.

RESUMO

BACKGROUND: Group B streptococcus (GBS) is a bacterium carried by 20-25 % of pregnant women in the UK, which can be transmitted from pregnant women to their babies at the time of birth. Women can be tested for GBS in pregnancy using a vaginal-rectal swab, however, this testing is currently not routinely offered in the UK. A large clinical trial is underway to determine the clinical and cost-effectiveness of routine testing (ISRCTN reference number ISRCTN49639731). A crucial part of understanding whether this type of test should be implemented is women's views on the acceptability of being offered GBS tests, their preferences towards testing procedures and their willingness to receive these tests. AIM: To explore women's views on the acceptability of different methods of Group B streptococcal bacteria (GBS) testing in pregnancy, including self-swabbing procedures. METHODS: A convenience sample of 19 women (5 pregnant and 14 postpartum) were interviewed using a semi-structured interview guide. Interviews were transcribed and analysed using systematic thematic analysis. RESULTS: Findings show that many of the women interviewed were not concerned about being offered a GBS test, were willing to provide a sample and felt positive towards samples being taken to detect GBS. Women varied in their preferences on the best time for sampling. Some thought being approached during pregnancy gave them time to understand the purpose of testing, prepare for what may happen next and ask questions about potential treatment if needed. Others thought labour was a good time to provide accurate results on GBS carriage at birth and reduce unnecessary worry during pregnancy. However, women were concerned that they may be unable to make an informed decision in labour due to time, pain and the prospect of birthing quickly. Women perceived clinician swabbing as more accurate than self-sampling; however, many thought clinician swabbing might be embarrassing so self-swabs should be available to increase uptake for some women. CONCLUSIONS: Overall, women thought both pregnancy and labour were acceptable times to test for GBS. The majority found both clinician and self-swabbing procedures acceptable; however, many had a preferred swabbing option and thought women should be given the choice of the swabbing procedure most acceptable to them. It is important that women are given information about GBS testing and its procedures in pregnancy regardless of when the GBS swabbing is performed.

RESUMO

Due to growing health disparities in underserved communities, a comprehensive approach is needed to train physicians to work effectively with patients who have cultures and belief systems different from their own. To address these complex healthcare inequities, Rowan-Virtua SOM implemented a new curriculum, The Tensegrity Curriculum, designed to expand beyond just teaching skills of cultural competence to include trainees' exploration of cultural humility. The hypothesis is that this component of the curriculum will mitigate health inequity by training physicians to recognize and interrupt the bias within themselves and within systems. Early outcomes of this curricular renewal process reveal increased student satisfaction as measured by course evaluations. Ongoing course assessments examine deeper understanding of the concepts of implicit bias, social determinants of health, systemic discrimination and oppression as measured by performance on graded course content, and greater commitment to continual self-evaluation and critique throughout their careers as measured by course feedback. Structured research is needed to understand the relationship between this longitudinal and integrated curricular design, and retainment or enhancement of empathy during medical training, along with its impact on health disparities and community-based outcomes.

RESUMO

OBJECTIVES: Transition of care when a patient moves between healthcare locations is a risk factor for medication errors and medicines-related preventable harm. The aims of this retrospective service evaluation were to understand, by classifying and quantifying, the nature of interventions made by community pharmacy when receiving a discharge medicines service referral from a secondary care hospital, with a focus on two groups of high-risk medicines supplied at discharge-oral anticoagulants and weak opioids following hip or knee surgery. METHODS: Records made on the PharmOutcomes™ platform by community pharmacists in response to referral for the NHS England discharge medicines service were analysed and summarized. This analysis was exploratory and interpretative in nature and used a convenience sample of patients who had consented for the service over 12 months from May 2022 to April 2023. KEY FINDINGS: During 12 months, 6811 referrals occurred, of which 71% were recorded as having different stages of the service completed on PharmOutcomes™. Medicines reconciliation, first-prescription review, and consultation stages decreased as patients progressed through the service. Slightly greater rates of completion were observed for patients receiving oral anticoagulants and for codeine or dihydrocodeine following hip and knee surgery, although overall referrals were low for this latter cohort. CONCLUSIONS: Through this service, community pharmacists are well placed to support the safe and effective use of medicines including oral anticoagulants and weak opioids posthospital discharge and potentially reduce incidents of avoidable harm. The variations in recorded completion rates across the three stages of the service and the apparent greater finalization rates for the high-risk medicines studied require further investigation.

RESUMO

Malaria transmission across sub-Saharan Africa is sensitive to rainfall and temperature. Whilst different malaria modelling techniques and climate simulations have been used to predict malaria transmission risk, most of these studies use coarse-resolution climate models. In these models convection, atmospheric vertical motion driven by instability gradients and responsible for heavy rainfall, is parameterised. Over the past decade enhanced computational capabilities have enabled the simulation of high-resolution continental-scale climates with an explicit representation of convection. In this study we use two malaria models, the Liverpool Malaria Model (LMM) and Vector-Borne Disease Community Model of the International Centre for Theoretical Physics (VECTRI), to investigate the effect of explicitly representing convection on simulated malaria transmission. The concluded impact of explicitly representing convection on simulated malaria transmission depends on the chosen malaria model and local climatic conditions. For instance, in the East African highlands, cooler temperatures when explicitly representing convection decreases LMM-predicted malaria transmission risk by approximately 55%, but has a negligible effect in VECTRI simulations. Even though explicitly representing convection improves rainfall characteristics, concluding that explicit convection improves simulated malaria transmission depends on the chosen metric and malaria model. For example, whilst we conclude improvements of 45% and 23% in root mean squared differences of the annual-mean reproduction number and entomological inoculation rate for VECTRI and the LMM respectively, bias-correcting mean climate conditions minimises these improvements. The projected impact of anthropogenic climate change on malaria incidence is also sensitive to the chosen malaria model and representation of convection. The LMM is relatively insensitive to future changes in precipitation intensity, whilst VECTRI predicts increased risk across the Sahel due to enhanced rainfall. We postulate that VECTRI's enhanced sensitivity to precipitation changes compared to the LMM is due to the inclusion of surface hydrology. Future research should continue assessing the effect of high-resolution climate modelling in impact-based forecasting.

RESUMO

BACKGROUND: Physiotherapy private practitioners represent a growing proportion of Australia's primary care workforce; however, they face significant barriers in integrating seamlessly within interprofessional teams. Historically, the landscape of primary care in Australia has been one where many physiotherapists work in monoprofessional private practice facilities at dispersed locations, potentially limiting collaborative and coordinated care. The aim of this study was to investigate strategies recommended by physiotherapists to promote effective interprofessional collaborative practice (IPCP) within the Australian private practice setting. METHODS: Using interpretive description as the guiding methodological framework, semi-structured interviews were conducted with 28 physiotherapists in 10 private practice sites in Queensland, Australia. RESULTS: Data analysis produced three themes that characterised physiotherapy private practitioners' recommendations to improve IPCP: (a) the need for improved funding and compensation, particularly addressing the limitations of the Medicare Chronic Disease Management program; (b) the development of integrated and secure digital communication systems to facilitate better information exchange; and (c) prioritising professional development and training to enhance collaboration. CONCLUSIONS: This research lays the groundwork for informed policy making to advance person-centred care and support the integration of services in the Australian healthcare system. The findings from this study indicate that promoting effective IPCP in physiotherapy private practice requires a comprehensive strategy that addresses systemic funding and compensation issues, enhances digital communication systems and optimises interprofessional education and training.

RESUMO

Rift Valley Fever (RVF) is a zoonosis transmitted by Aedes and Culex mosquitoes, and is considered a priority pathogen by the WHO. RVF epidemics mostly occur in Africa and can decimate livestock herds, causing significant economic losses and posing health risks for humans. RVF transmission is associated with the occurrence of El Niño events that cause floods in eastern Africa and favour the emergence of mosquitoes in wetlands. Different risk models have been developed to forecast RVF transmission risk but very few studies have validated models at pan-African scale. This study aims to validate the skill of the Liverpool Rift Valley Fever model (LRVF) in reproducing RVF epidemics over Africa and to explore the relationship between simulated climatic suitability for RVF transmission and large-scale climate modes of variability such as the El Niño Southern Oscillation (ENSO) and the Dipole Mode Index (DMI). Our results show that the LRVF model correctly simulates RVF transmission hotspots and reproduces large epidemics that affected African countries. LRVF was able to correctly reproduce major RVF epidemics in Somalia, Kenya, Zambia and to a lesser extent for Mauritania and Senegal. The positive phases of ENSO and DMI are associated with an increased risk of RVF over the Horn of Africa, with important time lags. Following research activities should focus on the development of predictive modelling systems at different time scales.

RESUMO

Physiotherapy private practitioners comprise a growing proportion of Australia's primary care workforce, yet their views and experiences of interprofessional collaborative practice (IPCP) are poorly documented. The aim of this study was to explore Australian physiotherapy private practitioners' opinions regarding IPCP. Twenty-eight semi-structured interviews were conducted with physiotherapists in 10 private practice sites in Queensland, Australia. Interviews were analyzed using reflexive thematic analysis. Data analysis produced five themes that characterized physiotherapists' perceptions of IPCP: (a) quality of care considerations; (b) not a one-size-fits-all approach; (c) the need for effective interprofessional communication; (d) fostering a positive work culture; and (e) fear of losing clientele. The findings from this study suggest that physiotherapy private practitioners value IPCP because it can deliver superior client outcomes, can strengthen interprofessional relationships, and has the potential to enhance the professional reputation of the organizations within which they work. Physiotherapists also claimed that IPCP can contribute to poor client outcomes when performed inappropriately, while some reported approaching interprofessional referrals with caution following instances of lost clientele. The mixed views toward IPCP in this study highlight the need to explore the facilitators and barriers to IPCP in the Australian physiotherapy private practice setting.

RESUMO

Metal-reducing bacteria have adapted the ability to respire extracellular solid surfaces instead of soluble oxidants. This process requires an electron transport pathway that spans from the inner membrane, across the periplasm, through the outer membrane, and to an external surface. Multiheme cytochromes are the primary machinery for moving electrons through this pathway. Recent studies show that the chiral-induced spin selectivity (CISS) effect is observable in some of these proteins extracted from the model metal-reducing bacteria, Shewanella oneidensis MR-1. It was hypothesized that the CISS effect facilitates efficient electron transport in these proteins by coupling electron velocity to spin, thus reducing the probability of backscattering. However, these studies focused exclusively on the cell surface electron conduits, and thus, CISS has not been investigated in upstream electron transfer components such as the membrane-associated MtrA, or periplasmic proteins such as small tetraheme cytochrome (STC). By using conductive probe atomic force microscopy measurements of protein monolayers adsorbed onto ferromagnetic substrates, we show that electron transport is spin selective in both MtrA and STC. Moreover, we have determined the spin polarization of MtrA to be ∼77% and STC to be ∼35%. This disparity in spin polarizations could indicate that spin selectivity is length dependent in heme proteins, given that MtrA is approximately two times longer than STC. Most significantly, our study indicates that spin-dependent interactions affect the entire extracellular electron transport pathway.

RESUMO

Caterpillar salivary glucose oxidase (GOX) can function as both an elicitor or as an effector of plant defense responses depending upon the system. Treatment with GOX reduces the stomatal aperture of tomato and soybean leaves, thereby reducing the emission of volatile organic compounds (VOCs), that are important indirect defense responses of plants by attracting natural enemies of the caterpillars. Here we examined the effect of fungal GOX (fungal glucose oxidases have been used to determine specificity in defense response elicitation) on stomatal closure of maize leaves and on the volatile emission pattern whole maize plants. We also used salivary gland homogenate from wild-type and CRISPR-Cas9 Helicoverpa zea mutants deficient in GOX activity to determine the effect caterpillar saliva with and without GOX had on maize volatile emission. Collecting volatiles at 2-hour intervals allowed us to examine the changes in emission over time. Fungal GOX reduced the stomatal aperture in maize leaves, which may have influenced the observed significant reduction in total green leaf volatile (GLV) emission. Furthermore, fungal GOX significantly increased the emission of several key terpenes: linalool, DMNT, and Z-ß-farnesene from maize, while salivary gland homogenate from wild type (WT; GOX+) H. zea increased the emission of α-pinene, ß-pinene, and ocimene compared to H. zea unable to synthesize GOX. This study addressed a significant knowledge gap about the effect of GOX on maize volatiles and provides a baseline for further research on the effect of GOX on the regulation of terpene synthase genes and their relation to terpene volatile emission.

RESUMO

BACKGROUND: 20-25% pregnant women in the UK carry group B streptococcus (GBS) which, if left undetected, is transmitted from pregnant mothers to their babies during birth in 36% of cases. This transmission leads to early onset GBS infection (EOGBS) in 1% of babies which is a significant cause of mortality and morbidity in newborns. The literature available suggests women's knowledge of GBS is low, with many women unaware of the GBS bacterium. In addition, attitudes towards GBS testing have not been widely examined, with research mostly focusing on attitudes towards potential GBS vaccination. AIM: To examine women's knowledge of GBS in pregnancy and their attitudes towards GBS testing. METHODS: Semi-structured interviews with 19 women (5 pregnant and 14 postpartum). Interviews were transcribed and analysed using systematic thematic analysis. RESULTS: Four main theme categories were identified. Participants had varying levels of awareness of GBS, with the information provided by health professionals not being clearly explained or the importance of GBS being downplayed. Participants wanted more information and to feel informed. Overall, the majority had positive attitudes towards being offered and taking up GBS testing, and this study identified some of the key factors influencing their decision. These included: seeing GBS testing as just another routine procedure during pregnancy; that it would lower the risk of their baby becoming unwell; provide reassurance; and allow them to prepare; and provide informed choices. Participants also expressed a few common concerns about GBS testing: questioning the invasiveness of the procedure; risks to themselves and the baby; and the risk of receiving antibiotics. CONCLUSIONS: Women need clear, detailed information about GBS and GBS testing, and women's concerns are important to address if routine GBS testing is implemented. The efficacy of implementing routine universal testing in the UK is currently being investigated in a large multi-centre clinical trial; the GBS3trial, further qualitative research is needed to look at the acceptability of different methods of GBS testing, as well as the acceptability of GBS testing to women in specific groups, such as those planning a home birth or those from different ethnic backgrounds.

RESUMO

Monogenic diseases are often studied in isolation due to their rarity. Here we utilize multiomics to assess 22 monogenic immune-mediated conditions with age- and sex-matched healthy controls. Despite clearly detectable disease-specific and "pan-disease" signatures, individuals possess stable personal immune states over time. Temporally stable differences among subjects tend to dominate over differences attributable to disease conditions or medication use. Unsupervised principal variation analysis of personal immune states and machine learning classification distinguishing between healthy controls and patients converge to a metric of immune health (IHM). The IHM discriminates healthy from multiple polygenic autoimmune and inflammatory disease states in independent cohorts, marks healthy aging, and is a pre-vaccination predictor of antibody responses to influenza vaccination in the elderly. We identified easy-to-measure circulating protein biomarker surrogates of the IHM that capture immune health variations beyond age. Our work provides a conceptual framework and biomarkers for defining and measuring human immune health.

RESUMO

Family physicians are at the front lines of mental health concerns and distress, yet often feel stymied in their attempts to fully support patients' biopsychosocial needs within the barriers of a fragmented health care system. This article describes a practice transformation designed to facilitate more empowered care experiences. We reflect on our interdisciplinary work as a family physician and a behavioral health consultant working closely together in a Primary Care Behavioral Health model within a university setting. We describe our collaborative approach to a composite character from clinical practice: a college student with symptoms of psychomotor depression who screened negative for mood and anxiety concerns. Akin to a musical ensemble, wherein the inclusion of each voice turns a solo into a symphony, we describe key details of interdisciplinary collaboration which promotes holistic care for patients and fulfilling biopsychosocial practice for us as colleagues.

RESUMO

OBJECTIVES: To establish a James Lind Alliance (JLA) Priority Setting Partnership (PSP) to identify research priorities relevant to the health and social care needs of adults with lived experience of recent and/or historical sexual violence/abuse. PARTICIPANTS: Adults (aged 18+ years) with lived experience of sexual violence/abuse (ie, 'survivors') were consulted for this PSP, alongside healthcare and social care professionals who support survivors across the public, voluntary, community, independent practice and social enterprise sectors. METHODS: In line with standard JLA PSP methodology, participants completed an initial online survey to propose research questions relevant to the health and social care needs of survivors. Research questions unanswered by current evidence were identified, and a second online survey was deployed to identify respondents' priorities from this list. Questions prioritised through the second survey were presented at a consensus meeting with key stakeholders to agree the top 10 research priorities using a modified nominal group technique approach. RESULTS: 223 participants (54% survivors) provided 484 suggested questions. Seventy-five unique questions unanswered by research were identified and subsequently ranked by 343 participants (60% survivors). A consensus meeting with 31 stakeholders (42% survivors) examined the top-ranking priorities from the second survey and agreed the top 10 research priorities. These included research into forms of support and recovery outcomes valued by survivors, how to best support people of colour/black, Asian and minority ethnic and lesbian, gay, bisexual, transgender, and queer (LGBTQ+) survivors, improving access to high-quality psychological therapies, reducing public misconceptions/stigma, the impact of involvement in the criminal justice system on well-being, and how physical and mental health services can become more 'trauma informed'. CONCLUSIONS: These research priorities identify crucial gaps in the existing evidence to better support adult survivors of sexual violence and abuse. Researchers and funders should prioritise further work in these priority areas identified by survivors and the professionals who support them.

RESUMO

CONTEXT: Research and policy studies alike have enumerated population and community health benefits of system integration between medical, public health, and social entities. The emergence of the COVID-19 pandemic revealed the necessity of a well-trained and adequately staffed public health and medical workforce in order to process SARS-CoV-2 cases and prevent subsequent transmission. Higher education systems, in particular, represented defined populations of exposure and transmission. Opportunities existed for collaboration and task sharing between institutions of higher education and local public health departments to limit spread and impacts. PROGRAM: This article describes the Pandemic Response Officer (PRO) program at Cornell University, a team of staff and students created during the intensity of the pandemic to benefit the Tompkins County and Cornell University communities. IMPLEMENTATION: The PRO program was formed in January 2021, with an original team of 8 individuals, working iteratively to investigate and support employee cases and exposures. Implementation was motivated by Cornell University's dual responsibility as a large employer that also possessed SARS-CoV-2 test results of employees. PROs loaded case information into a shared HIPPA-compliant electronic record that collected information for case notification, case investigation, isolation support, contact tracing, contact notification, and quarantine support. Over time, the PROs grew to a team of 25, gaining responsibilities as university and public health systems shared roles to maximize resources. EVALUATION: From January 1 to December 31, 2021, PROs managed 773 employee and 2943 student cases. During the Omicron surge (November 28-December 31, 2021), PROs saved the public health department an estimated 2797 hours of effort, equating to more than 10 professionals working full-time, evenings and weekends, to process cases and contacts during this interval. DISCUSSION: By integrating efforts between a university and public health agency, this intervention minimized SARS-CoV-2 transmission via expedient case support and alleviated strain on public health systems by expanding the public health workforce.

RESUMO

One of the many functions of reduction-oxidation (redox) cofactors is to mediate electron transfer in biological enzymes catalyzing redox-based chemical transformation reactions. There are numerous examples of enzymes that utilize redox cofactors to form electron transfer relays to connect catalytic sites to external electron donors and acceptors. The compositions of relays are diverse and tune transfer thermodynamics and kinetics towards the chemical reactivity of the enzyme. Diversity in relay design is exemplified among different members of hydrogenases, enzymes which catalyze reversible H2 activation, which also couple to diverse types of donor and acceptor molecules. The [FeFe]-hydrogenase I from Clostridium acetobutylicum (CaI) is a member of a large family of structurally related enzymes where interfacial electron transfer is mediated by a terminal, non-canonical, His-coordinated, [4Fe-4S] cluster. The function of His coordination was examined by comparing the biophysical properties and reactivity to a Cys substituted variant of CaI. This demonstrated that His coordination strongly affected the distal [4Fe-4S] cluster spin state, spin pairing, and spatial orientations of molecular orbitals, with a minor effect on reduction potential. The deviations in these properties by substituting His for Cys in CaI, correlated with pronounced changes in electron transfer and reactivity with the native electron donor-acceptor ferredoxin. The results demonstrate that differential coordination of the surface localized [4Fe-4S]His cluster in CaI is utilized to control intermolecular and intramolecular electron transfer where His coordination creates a physical and electronic environment that enables facile electron exchange between electron carrier molecules and the iron-sulfur cluster relay for coupling to reversible H2 activation at the catalytic site.

RESUMO

To minimize the impacts of COVID-19 and to keep campus open, Cornell University's Ithaca, NY, campus implemented a comprehensive process to monitor COVID-19 spread, support prevention practices, and assess early warning indicators linked to knowledge, behaviors, and attitudes of campus community members. The integrated surveillance approach informed leadership and allowed for prompt adjustments to university policies and practices through evidence-based decisions. This approach enhanced healthy behaviors and promoted the well-being and safety of all community members. (Am J Public Health. 2022;112(7):980-984. https://doi.org/10.2105/AJPH.2022.306838).
