RESUMO

OBJECTIVES: Comprehensive data on the genomic epidemiology of hospital-associated Klebsiella pneumoniae in Ghana are scarce. This study investigated the genomic diversity, antimicrobial resistance patterns, and clonal relationships of 103 clinical K. pneumoniae isolates from five tertiary hospitals in Southern Ghana-predominantly from paediatric patients aged under 5 years (67/103; 65%), with the majority collected from urine (32/103; 31%) and blood (25/103; 24%) cultures. METHODS: We generated hybrid Nanopore-Illumina assemblies and employed Pathogenwatch for genotyping via Kaptive [capsular (K) locus and lipopolysaccharide (O) antigens] and Kleborate (antimicrobial resistance and hypervirulence) and determined clonal relationships using core-genome MLST (cgMLST). RESULTS: Of 44 distinct STs detected, ST133 was the most common, comprising 23% of isolates (n = 23/103). KL116 (28/103; 27%) and O1 (66/103; 64%) were the most prevalent K-locus and O-antigen types. Single-linkage clustering highlighted the global spread of MDR clones such as ST15, ST307, ST17, ST11, ST101 and ST48, with minimal allele differences (1-5) from publicly available genomes worldwide. Conversely, 17 isolates constituted novel clonal groups and lacked close relatives among publicly available genomes, displaying unique genetic diversity within our study population. A significant proportion of isolates (88/103; 85%) carried resistance genes for ≥3 antibiotic classes, with the blaCTX-M-15 gene present in 78% (n = 80/103). Carbapenem resistance, predominantly due to blaOXA-181 and blaNDM-1 genes, was found in 10% (n = 10/103) of the isolates. CONCLUSIONS: Our findings reveal a complex genomic landscape of K. pneumoniae in Southern Ghana, underscoring the critical need for ongoing genomic surveillance to manage the substantial burden of antimicrobial resistance.

RESUMO

PURPOSE: Multiple myeloma (MM) in rural western Kenya is characterized by under and late diagnosis with poor long-term outcomes. Inadequate skilled rural health care teams are partly to blame. The Extension for Community Healthcare Outcomes (ECHO) model attempts to bridge this skills gap by linking rural primary/secondary health care teams (spokes) to myeloma experts in a tertiary care center (hub) in a longitudinal training program. METHODS: A hub team comprising myeloma experts and administrators from Moi Teaching and Referral Hospital/Academic Model Providing Access to Healthcare was assembled and spoke sites were recruited from rural health care facilities across western Kenya. A curriculum was developed by incorporating input from spokes on their perceived skills gaps in myeloma. Participants joined sessions remotely through virtual meeting technology. ECHO sessions consisted of a spoke-led case presentation with guided discussion followed by an expert-led lecture. An end-of-program survey was used to evaluate participant satisfaction, knowledge, and practice patterns. RESULTS: A total of eight sessions were conducted between April and November 2021 with a median of 40 attendees per session drawn from diverse health care disciplines. Twenty-four spoke sites were identified from 15 counties across western Kenya. The majority of attendees reported satisfaction with the ECHO program (25 of 29) and improvement in their myeloma knowledge (24 of 29). There were 74 new myeloma diagnoses made at the hub site in 2021, representing a 35% increase from the previous 3-year average despite the COVID-19 pandemic that suppressed health care access globally. RECOMMENDATIONS: The pilot ECHO model was successfully implemented in myeloma training for rural-based health care teams. Key attributes included collaborative curriculum development, interactive case-based bidirectional learning, and multidisciplinary engagement.

RESUMO

Importance: Dialysis patient care technicians (PCTs) play a critical role in US in-center hemodialysis (HD) care, but little is known about the association of PCT staffing with patient outcomes at US HD facilities. Objective: To estimate the associations of in-center HD patient outcomes with facility-level PCT staffing. Design, Setting, and Participants: This was a retrospective cohort study, with data analysis performed from March 2023 to January 2024. Data on US patients with end-stage kidney disease and their treatment facilities were obtained from the US Renal Data System. Participants included patients (aged 18-100 years) initiating in-center HD between January 1, 2016, and December 31, 2018, who continued receiving in-center HD for 90 days or more and had data on PCT staffing at their initial treating HD facility. Exposure: Facility-level patient-to-PCT ratios (number of HD patients divided by the number of PCTs reported by the treating facility in the prior year), categorized into quartiles (highest quartile denotes the highest PCT burden). Main Outcomes and Measures: Patient-level outcomes included 1-year patient mortality, hospitalization, and transplantation. Associations of outcomes with quartile of patient-to-PCT ratio were estimated using incidence rate ratios (IRRs) from mixed-effects Poisson regression, with adjustment for patient demographics and clinical and facility factors. Results: A total of 236 126 patients (mean [SD] age, 63.1 [14.4] years; 135 952 [57.6%] male; 65 945 [27.9%] Black; 37 777 [16.0%] Hispanic; 153 637 [65.1%] White; 16 544 [7.0%] other race; 146 107 [61.9%] with diabetes) were included. After full adjustment, the highest vs lowest quartile of facility-level patient-to-PCT ratio was associated with a 7% higher rate of patient mortality (IRR, 1.07; 95% CI, 1.02-1.12), a 5% higher rate of hospitalization (IRR, 1.05; 95% CI, 1.02-1.08), an 8% lower rate of waitlisting (IRR, 0.92; 95% CI, 0.85-0.98), and a 20% lower rate of transplant (IRR, 0.80; 95% CI, 0.71-0.91). The highest vs lowest quartile of patient-to-PCT ratio was also associated with an 8% higher rate of sepsis-related hospitalization (IRR, 1.08; 95% CI, 1.03-1.14) and a 15% higher rate of vascular access-related hospitalization (IRR, 1.15; 95% CI, 1.03-1.28). Conclusions and Relevance: These findings suggest that initiation of treatment in facilities with the highest patient-to-PCT ratios may be associated with worse early mortality, hospitalization, and transplantation outcomes. These results support further investigation of the impact of US PCT staffing on patient safety and quality of US in-center HD care.

RESUMO

BACKGROUND: Sexual behavior may influence the composition of the male urethral microbiota, but this hypothesis has not been tested in longitudinal studies of men who have sex with men (MSM). METHODS: From December 2014 to July 2018, we enrolled MSM with nongonococcal urethritis (NGU) attending a sexual health clinic. Men attended 5 in-clinic visits at 3-week intervals, collected weekly urine specimens at home, and reported daily antibiotics and sexual activity on weekly diaries. We applied broad-range 16S rRNA gene sequencing to urine. We used generalized estimating equations to estimate the association between urethral sexual exposures in the prior 7 days (insertive oral sex [IOS] only, condomless insertive anal intercourse [CIAI] only, IOS with CIAI [IOS + CIAI], or none) and Shannon index, number of species (observed, oral indicator, and rectal indicator), and specific taxa, adjusting for recent antibiotics, age, race/ethnicity, HIV, and preexposure prophylaxis. RESULTS: Ninety-six of 108 MSM with NGU attended ≥1 follow-up visit. They contributed 1140 person-weeks of behavioral data and 1006 urine specimens. Compared with those with no urethral sexual exposures, those with IOS only had higher Shannon index ( P = 0.03 ) but similar number of species and presence of specific taxa considered, adjusting for confounders; the exception was an association with Haemophilus parainfluenzae . CIAI only was not associated with measured aspects of the urethral microbiota. IOS + CIAI was only associated with presence of H. parainfluenzae and Haemophilus . CONCLUSIONS: Among MSM after NGU, IOS and CIAI did not seem to have a substantial influence on measured aspects of the composition of the urethral microbiota.

RESUMO

Complement-mediated diseases can be treated using systemic inhibitors. However, complement components are abundant in circulation, affecting systemic inhibitors' exposure and efficacy. Furthermore, because of complement's essential role in immunity, systemic treatments raise infection risk in patients. To address these challenges, we developed antibody fusion proteins combining the alternative-pathway complement inhibitor factor H (fH1-5) with an anti-C3d monoclonal antibody (C3d-mAb-2fH). Because C3d is deposited at sites of complement activity, this molecule localizes to tissue complement while minimizing circulating complement engagement. These fusion proteins bind to deposited complement in diseased human skin sections and localize to activated complement in a primate skin injury model. We further explored the pharmacology of C3d-mAb-2fH proteins in rodent models with robust tissue complement activation. Doses of C3d-mAb-2fH >1 mg/kg achieved >75% tissue complement inhibition in mouse and rat injury models while avoiding circulating complement blockade. Glomerular-specific complement inhibition reduced proteinuria and preserved podocyte foot-process architecture in rat membranous nephropathy, indicating disease-modifying efficacy. These data indicate that targeting local tissue complement results in durable and efficacious complement blockade in skin and kidney while avoiding systemic inhibition, suggesting broad applicability of this approach in treating a range of complement-mediated diseases.

RESUMO

Rationale & Objective: Technicians caring for patients receiving dialysis play a critical, frontline role in the care of patients receiving dialysis in the United States. We sought to provide a comprehensive description and identify correlates of US in-center hemodialysis facility patient care technician staffing patterns. Study Design: This was an ecological study. Setting & Participants: US facilities providing hemodialysis and reporting patient care technician staffing, identified using the US Renal Data System. Exposures: Geography, year, and facility characteristics, including aggregated patient characteristics. Outcomes: The study outcome was facility-reported patient-to-patient care technician ratio. Analytical Approach: We examined patient-to-patient care technician ratios by US state and over time and also estimated the differences in patient-to-patient care technician ratios associated with facility characteristics, using robust regression with adjustment for facility-level covariates. Results: The median patient-to-patient care technician ratio among 6,862 US facilities in 2019 was 9.9 (25th-75th percentiles, 8.2-12.0). Median 2019 patient-to-patient care technician ratios varied substantially by US state and region. There was an overall decline (from 10.6 to 9.9) in median patient-to-patient care technician ratios from 2004 to 2019, whereas the percentage of positions that were unfilled increased (from 2.8% to 3.5%). After adjustment, large dialysis organization status (ß, -0.42; 95% CI, -0.61 to -0.23) and larger facility size (ß, -0.51; 95% CI, -0.68 to -0.33) were associated with lower patient-to-patient care technician ratios. Higher patient-to-registered nurse (ß, 0.80; 95% CI, 0.65-0.94) and patient-to-social worker (ß, 0.53; 95% CI, 0.37-0.70) ratios, presence of licensed vocational nurses or licensed practical nurses at the clinic (ß, 0.83; 95% CI, 0.53-1.12), and location in a poverty area (ß, 0.29; 95% CI, 0.13-0.44) were all associated with higher patient-to-patient care technician ratios. Aggregated patient characteristics of patients treated at the facilities were generally not associated with patient-to-patient care technician ratio after adjustment. Limitations: Limited causal inference and potential shifts in staffing after 2019. Conclusions: US dialysis facilities vary considerably in their patient care technician staffing by geography, over time, and by various facility characteristics. Further investigation of US patient care technician staffing is warranted and could lead to better, more stable dialysis staffing, improved staff and patient satisfaction, and higher quality of care.


In the United States, patient care technicians play an important role in hemodialysis care. Although ongoing staffing shortages and turnover among other hemodialysis care providers have been described, little is known about US patient care technician staffing. Examining national data reported by dialysis facilities, we found variability in patient care technician staffing by geography, over time (with fewer patients per patient care technician in more recent years), and by various facility characteristics. This information can be used to target staff recruitment and retention interventions at facilities where patient care technician staffing may be more challenging.

RESUMO

Purpose: Assisted Living (AL) residents are embedded in "care convoys" comprised of a dynamic network of formal and informal care partners. Using the convoys of care model-a multi-level framework connecting care convoy properties to resident outcomes-we examined healthcare management and communication between convoy members. We recommend strategies to engage primary care in supporting collaboration, communication, and consensus-building for older adults and their convoys. Methods: Data were collected from the longitudinal study, Convoys of Care: Developing Collaborative Care Partnerships in AL. Fifty residents and their care convoy members (N = 169) were followed in eight AL homes in Georgia over 2 years. Original data were analyzed using Grounded Theory Methods of qualitative data, including formal and informal interviewing, participant observation, and record review. Results: The convoys of care model provide an innovative perspective that will assist providers in supporting AL residents and their care partners to achieve better care outcomes. Findings demonstrate the utility of understanding the structure and function of social resources and implications for improving healthcare outcomes. Conclusion: This research informs the work of physicians and mid-level providers with patients in AL by providing strategies to uncover specific social determinants of health. Recommendations for use in patient encounters are enumerated.

RESUMO

INTRODUCTION: In Kenya, patients with breast cancer predominantly present with late-stage disease and experience poor outcomes. To promote early-stage diagnosis, we implemented the Academic Model Providing Access to Healthcare (AMPATH) Breast and Cervical Cancer Control Program (ABCCCP) in Western Kenya. OBJECTIVE: The aim of this study was to assess differences between patients presenting to health facilities and health fairs. METHODS: This was an institutional Review and Ethics Commitee-approved retrospective cohort study of all individuals who underwent clinical breast examination (CBE) via local healthcare workers in Western Kenya. From 2017 to 2021, the program hosted health fairs, and trained healthcare providers at health facilities to complete CBEs. Results were analyzed using the Chi-square and Kruskal-Wallis tests, with an α < 0.05. RESULTS: Over a 5-year period, the ABCCCP completed 61,812 CBEs with 75.9% (n = 46,902) performed at a health facility. Patients presenting to health fairs were older (44 vs. 38 years; p < 0.0001) and had higher risk factor rates including early menarche, family history of breast and ovarian cancer, and use of alcohol or smoking. Only 27.6% of patients with an abnormal CBE underwent core needle biopsy, and only 5.2% underwent repeat CBE over the 5-year period, of whom 90.3% presented to health facilities. CONCLUSIONS: Successful uptake of CBE through the ABCCCP is the first step to introduce breast health awareness (BHA). Benefits of broad advertisements for health fairs in promoting BHA may be limited to a single event. Poor rates of repeat examinations and diagnostic testing of abnormal CBEs indicate additional resources should be allocated to educating patients, including about possible treatment trajectories for breast cancer.

RESUMO

Improvisational (improv) theatre skill development holds promise for improving the dementia capability of care partners. In this report, we present analysis of data from an ongoing study on meaningful engagement and quality of life among assisted living (AL) residents with dementia. Using ethnographic methods, we collected data from persons with dementia (n = 59) and their care partners (n = 165) in six diverse AL communities each studied for one year. Building cumulatively on past work and existing literature, we demonstrate the potential benefits of training care partners to use improv skills. We discuss implications, including the need for intervention research.

RESUMO

α-Synuclein is a presynaptic protein that regulates synaptic vesicle (SV) trafficking. In Parkinson's disease (PD) and dementia with Lewy bodies (DLB), α-synuclein aberrantly accumulates throughout neurons, including at synapses. During neuronal activity, α-synuclein is reversibly phosphorylated at serine 129 (pS129). While pS129 comprises ∼4% of total α-synuclein under physiological conditions, it dramatically increases in PD and DLB brains. The impacts of excess pS129 on synaptic function are currently unknown. We show here that compared with wild-type (WT) α-synuclein, pS129 exhibits increased binding and oligomerization on synaptic membranes and enhanced vesicle "microclustering" in vitro. Moreover, when acutely injected into lamprey reticulospinal axons, excess pS129 α-synuclein robustly localized to synapses and disrupted SV trafficking in an activity-dependent manner, as assessed by ultrastructural analysis. Specifically, pS129 caused a declustering and dispersion of SVs away from the synaptic vicinity, leading to a significant loss of total synaptic membrane. Live imaging further revealed altered SV cycling, as well as microclusters of recently endocytosed SVs moving away from synapses. Thus, excess pS129 caused an activity-dependent inhibition of SV trafficking via altered vesicle clustering/reclustering. This work suggests that accumulation of pS129 at synapses in diseases like PD and DLB could have profound effects on SV dynamics.

RESUMO

Duchenne muscular dystrophy (DMD) is caused by mutations in the DMD gene that disrupt the open reading frame and thus prevent production of functional dystrophin proteins. Recent advances in DMD treatment, notably exon skipping and AAV gene therapy, have achieved some success aimed at alleviating the symptoms related to progressive muscle damage. However, they do not address the brain comorbidities associated with DMD, which remains a critical aspect of the disease. The mdx52 mouse model recapitulates one of the most frequent genetic pathogenic variants associated with brain involvement in DMD. Deletion of exon 52 impedes expression of two brain dystrophins, Dp427 and Dp140, expressed from distinct promoters. Interestingly, this mutation is eligible for exon skipping strategies aimed at excluding exon 51 or 53 from dystrophin mRNA. We previously showed that exon 51 skipping can restore partial expression of internally deleted yet functional Dp427 in the brain following intracerebroventricular (ICV) injection of antisense oligonucleotides (ASO). This was associated with a partial improvement of anxiety traits, unconditioned fear response, and Pavlovian fear learning and memory in the mdx52 mouse model. In the present study, we investigated in the same mouse model the skipping of exon 53 in order to restore expression of both Dp427 and Dp140. However, in contrast to exon 51, we found that exon 53 skipping was particularly difficult in mdx52 mice and a combination of multiple ASOs had to be used simultaneously to reach substantial levels of exon 53 skipping, regardless of their chemistry (tcDNA, PMO, or 2'MOE). Following ICV injection of a combination of ASO sequences, we measured up to 25% of exon 53 skipping in the hippocampus of treated mdx52 mice, but this did not elicit significant protein restoration. These findings indicate that skipping mouse dystrophin exon 53 is challenging. As such, it has not yet been possible to answer the pertinent question whether rescuing both Dp427 and Dp140 in the brain is imperative to more optimal treatment of neurological aspects of dystrophinopathy.

RESUMO

Introduction: Pharmacogenomics (PGx) aims to maximize drug benefits while minimizing risk of toxicity. Although PGx has proven beneficial in many settings, clinical uptake lags. Lack of clinician confidence and limited availability of PGx testing can deter patients from completing PGx testing. A few novel PGx clinic models have been described as a way to incorporate PGx testing into the standard of care. Background: A PGx clinic was implemented to fill an identified gap in provider availability, confidence, and utilization of PGx across our health system. Through a joint pharmacist and Advanced Practice Provider (APP) collaborative clinic, patients received counseling and PGx medication recommendations both before and after PGx testing. The clinic serves patients both in-person and virtually across four states in the upper Midwest. Results: The majority of patients seen in the PGx clinic during the early months were clinician referred (77%, n = 102) with the remainder being self-referred. Patients were, on average, taking two medications with Clinical Pharmacogenetics Implementation Consortium guidelines. Visits were split almost equally between in-person and virtual visits. Conclusion: Herein, we describe the successful implementation of an interdisciplinary PGx clinic to further enhance our PGx program. Throughout the implementation of the PGx clinic we have learned valuable lessons that may be of interest to other implementors. Clinicians were actively engaged in clinic referrals and early adoption of telemedicine was key to the clinic's early successes.

RESUMO

Introduction: Family engagement and patient-family-centered care are vitally important to improve outcomes for patients, families, providers, hospitals, and communities. Both constructs prioritize providers forming partnerships with patients and their families. The domains of family-engaged care include presence, communication, shared-decision making, family needs, contribution to care, and collaboration at the institutional level. This integrative review describes the extent to which the domains of family engagement are present in the literature about Covid-era hospital visiting policies. Methods: A search of four databases resulted in 127 articles and one added through data mining. After review, 28 articles were synthesized and analyzed into an integrative review of family engagement in the hospital with Covid-era visiting policies as the backdrop. Results: The 28-article review resulted in an international, multidisciplinary perspective of diverse study designs. The review's sample population includes 6,984 patients, 1,126 family members, 1,174 providers, 96 hospitals, 50 health centers, 1 unit, and 257 documents. While all the domains are represented, presence is the prevailing domain, identified in 25 out of the 28 (89%). Discussion: Presence is recognized as facilitating the other domains. Because the concept of collaboration is largely absent in the literature, it may provide healthcare institutions with a growth opportunity to facilitate and promote family engagement. This review is the first step in operationalizing family engagement in the hospital setting, especially when presence is challenging.

RESUMO

INTRODUCTION: Shielding aimed to protect those predicted to be at highest risk from COVID-19 and was uniquely implemented in the UK during the first year of the pandemic from March 2020. As the first stage in the EVITE Immunity evaluation (Effects of shielding for vulnerable people during COVID-19 pandemic on health outcomes, costs and immunity, including those with cancer:quasi-experimental evaluation), we generated a logic model to describe the programme theory underlying the shielding intervention. DESIGN AND PARTICIPANTS: We reviewed published documentation on shielding to develop an initial draft of the logic model. We then discussed this draft during interviews with 13 key stakeholders involved in putting shielding into effect in Wales and England. Interviews were recorded, transcribed and analysed thematically to inform a final draft of the logic model. RESULTS: The shielding intervention was a complex one, introduced at pace by multiple agencies working together. We identified three core components: agreement on clinical criteria; development of the list of people appropriate for shielding; and communication of shielding advice. In addition, there was a support programme, available as required to shielding people, including food parcels, financial support and social support. The predicted mechanism of change was that people would isolate themselves and so avoid infection, with the primary intended outcome being reduction in mortality in the shielding group. Unintended impacts included negative impact on mental and physical health and well-being. Details of the intervention varied slightly across the home nations of the UK and were subject to minor revisions during the time the intervention was in place. CONCLUSIONS: Shielding was a largely untested strategy, aiming to mitigate risk by placing a responsibility on individuals to protect themselves. The model of its rationale, components and outcomes (intended and unintended) will inform evaluation of the impact of shielding and help us to understand its effect and limitations.

RESUMO

The conversion of fibroblasts into myogenic cells is a powerful tool to both develop and test therapeutic strategies and to perform in-depth investigations of neuromuscular disorders, avoiding the need for muscle biopsies. We developed an easy, reproducible, and high-efficiency lentivirus-mediated transdifferentiation protocol, that can be used to convert healthy donor fibroblasts and a promising new cellular model, urinary stem cells (USCs), into myoblasts, that can be further differentiated into multinucleated myotubes in vitro. Transcriptome and proteome profiling of specific muscle markers (desmin, myosin, dystrophin) was performed to characterize both the myoblasts and myotubes derived from each cell type and to test the transdifferentiation-inducing capacity of MYOD1 in fibroblasts and USCs. Specifically, the Duchenne muscular dystrophy (DMD) transcripts and proteins, including both the full-length Dp427 and the short Dp71 isoform, were evaluated. The protocol was firstly developed in healthy donor fibroblasts and USCs and then used to convert DMD patients' fibroblasts, with the aim of testing the efficacy of an antisense drug in vitro. Technical issues, limitations, and problems are explained and discussed. We demonstrate that MyoD-induced-fibroblasts and USCs are a useful in vitro model of myogenic cells to investigate possible therapies for neuromuscular diseases.

RESUMO

PURPOSE: To examine whether there are differences in meeting treatment goals between pelvic floor physical therapy (PFPT) patients who participated in a majority of telehealth visits versus those who participated in mostly traditional office visits at a community hospital. METHODS: Retrospective chart review was performed among patients who received PFPT from April 2019 to February 2021. Cohorts were defined as "Mostly Office Visits" (> 50% office visits) and "Mostly Telehealth" (> / = 50% telehealth visits). Primary outcome measures included demographic data, number/type of visit for each patient, number of no-show/cancelation appointments, and number of patients discharged meeting PFPT goals. Statistical significance was defined as p < 0.05. RESULTS: 234 subjects met criteria for the "Mostly Office Visit" cohort and 48 subjects met criteria for the "Mostly Telehealth" cohort. There were no significant differences observed in age (p = 0.919), BMI (p = 0.817), race/ethnicity (p = 0.170) or insurance type (p = 0.426) between cohorts. There was no significant difference in meeting PFPT goals between the "Mostly Office Visit" cohort (24.4%) and the "Mostly Telehealth" cohort (35.4%) (p = 0.113). There was no difference in the number of canceled visits per patient (mean cancelations "Office visit" 1.98; "Telehealth" 1.63; p = 0.246) and the number of no-show visits per patient (mean no-show's "Office visit" 0.23; "Telehealth" 0.31; p = 0.297) between cohorts. CONCLUSION: There was no difference in meeting discharge goals regardless of whether a patient participated in mostly telehealth visits versus mostly traditional office visits. Therefore, we can conclude that participating in mostly provider-led telehealth visits can be equally efficacious at providing competent PFPT care.
