A Systematic Review of Oral Pre-exposure Prophylaxis HIV Adherence Interventions.

ABSTRACT: Clinical trials of pre-exposure prophylaxis (PrEP) to prevent HIV infection have established its efficacy as upwards of 99%. Despite this, the effectiveness of this medication has been shown to be diminished by individual factors, such as medication adherence. We completed a systematic review to identify and describe interventions to improve oral PrEP adherence. Overall, 16 articles were located. Two of the articles reported on results from the same trial and were collapsed for analysis, bringing the total to 15 studies. Twelve unique PrEP adherence interventions were tested, with the most common intervention being the use of mobile phone technology, which was used in 7 (46%) of the studies. Ten (67%) studies found that medication adherence improved when participants received an intervention to support adherence. Adherence intervention strategies effectively improved PrEP adherence. Further research into PrEP adherence interventions is warranted, particularly among diverse groups.

Nasal Lining Reconstruction with Prelaminated Forehead Flap.

A successful nasal reconstruction relies heavily on a stable internal lining. Larger defects pose unique challenges for internal lining reconstruction as obtaining tissue of adequate size while maintaining airway patency is difficult. The prelamination technique uses a staged skin graft to the paramedian forehead flap prior to transfer. As such, a composite flap can be later transferred to reconstruct internal and external nasal defects concomitantly. This article reviews the current background, techniques, and clinical considerations in the use of the prelaminated forehead flap for nasal lining reconstruction in partial to total nasal defects.

Adverse events associated with anastomotic coupling devices in microvascular reconstruction.

OBJECTIVE: In light of the recent US Food and Drug Administration (FDA) Class 2 safety recall notice for anastomotic coupling devices, it is important to understand related adverse events. The aim of this study was to characterize adverse events in anastomotic coupling devices for microvascular reconstruction. METHODS: A retrospective cross-sectional analysis using the 2011 to 2021 US FDA Manufacturer and User Facility Device Experience (MAUDE) database. All reports of adverse events involving anastomotic coupling devices were retrieved from the MAUDE database. Descriptive statistics were used to analyze categorized events. RESULTS: There were a total of 293 documented adverse events related to anastomotic coupling devices. These adverse events resulted in 91 (31.1 %) patient injuries and 239 (81.6 %) device malfunctions. The most frequent patient problems were thrombosis/hematoma (n = 38; 41.8 %), unspecified injury (n = 31; 34.1 %), and failure to anastomose (n = 13; 14.3 %). Free flap necrosis was reported in 42 % of thrombosis/hematoma cases (n = 16). The most common malfunctions were devices operating differently than expected (n = 74; 31.0 %), connection problems (n = 41; 17.2 %), and twisted/bent material (n = 19; 7.9 %). There was no significant trend in the number of adverse events over the study period (p > 0.05). CONCLUSIONS: Adverse events from anastomotic coupling devices represent an important and modifiable factor in free tissue failure. Adverse events are predominately related to devices operating differently than expected and may result in vascular compromise of the free flap. Reconstructive surgeons should be cognizant of defective anastomotic coupling devices and be prepared to utilize traditional hand-sewn anastomosis.

Correcting for Rater Effects in Operating Room Surgical Skills Assessment.

OBJECTIVE: To estimate and adjust for rater effects in operating room surgical skills assessment performed using a structured rating scale for nasal septoplasty. METHODS: We analyzed survey responses from attending surgeons (raters) who supervised residents and fellows (trainees) performing nasal septoplasty in a prospective cohort study. We fit a structural equation model with the rubric item scores regressed on a latent component of skill and then fit a second model including the rating surgeon as a random effect to model a rater-effects-adjusted latent surgical skill. We validated this model against conventional measures including the level of expertise and post-graduation year (PGY) commensurate with the trainee's performance, the actual PGY of the trainee, and whether the surgical goals were achieved. RESULTS: Our dataset included 188 assessments by 7 raters and 41 trainees. The model with one latent construct for surgical skill and the rater as a random effect was the best. Rubric scores depended on how severe or lenient the rater was, sometimes almost as much as they depended on trainee skill. Rater-adjusted latent skill scores increased with attending-estimated skill levels and PGY of trainees, increased with the actual PGY, and appeared constant over different levels of achievement of surgical goals. CONCLUSION: Our work provides a method to obtain rater effect adjusted surgical skill assessments in the operating room using structured rating scales. Our method allows for the creation of standardized (i.e., rater-effects-adjusted) quantitative surgical skill benchmarks using national-level databases on trainee assessments. LEVEL OF EVIDENCE: N/A Laryngoscope, 2024.

Hybrid immunity to SARS-CoV-2 arises from serological recall of IgG antibodies distinctly imprinted by infection or vaccination.

We used plasma IgG proteomics to study the molecular composition and temporal durability of polyclonal IgG antibodies triggered by ancestral SARS-CoV-2 infection, vaccination, or their combination ("hybrid immunity"). Infection, whether primary or post-vaccination, mainly triggered an anti-spike antibody response to the S2 domain, while vaccination predominantly induced anti-RBD antibodies. Immunological imprinting persisted after a secondary (hybrid) exposure, with >60% of the ensuing serological response originating from the initial antibodies generated during the first exposure. We highlight one instance where hybrid immunity arising from breakthrough infection resulted in a marked increase in the breadth and affinity of a highly abundant vaccination-elicited plasma IgG antibody, SC27. With an intrinsic binding affinity surpassing a theoretical maximum (K D < 5 pM), SC27 demonstrated potent neutralization of various SARS-CoV-2 variants and SARS-like zoonotic viruses (IC 50 ∼0.1-1.75 nM) and provided robust protection in vivo . Cryo-EM structural analysis unveiled that SC27 binds to the RBD class 1/4 epitope, with both VH and VL significantly contributing to the binding interface. These findings suggest that exceptionally broad and potent antibodies can be prevalent in plasma and can largely dictate the nature of serological neutralization. HIGHLIGHTS: ▪ Infection and vaccination elicit unique IgG antibody profiles at the molecular level▪ Immunological imprinting varies between infection (S2/NTD) and vaccination (RBD)▪ Hybrid immunity maintains the imprint of first infection or first vaccination▪ Hybrid immune IgG plasma mAbs have superior neutralization potency and breadth.

Targeted HIV Self-Testing Identifies Persons with Undiagnosed HIV and Active Engagement Links them to Care: The GetaKit Study.

Current international HIV testing guidelines recommend that HIV negative persons from HIV priority groups complete repeat screening every 3-6 months; local guidelines in our jurisdiction recommend that such retesting should occur every 3 months. Such an approach allows for timely HIV diagnosis and linkage to care - and aligns with the UNAIDS 95-95-95 targets to have 95% of undiagnosed persons be aware of their HIV status. To meet these aims, new approaches to HIV testing have been developed, including our HIV self-testing initiative, GetaKit.ca, which uses an online screening algorithm to determine eligibility and has built in pathways for re-test reminders, linkage HIV prevention care, and rapid follow-up for positive test results. To understand self-testing frequency in relation to our local recommendations for resting every 3 months, we evaluated data from participants who ordered repeat HIV self-tests through GetaKit.ca. Descriptive analyses were performed on participant characteristics and chi-square tests were performed on aggregated participant risk data. During the study period, 5235 HIV self-tests were distributed to 3627 participants, of whom, 26% ordered more than once and 27% belonged to an HIV priority population. Participants who retested were more likely to have been white, male, and part of an HIV priority population; they were also more likely to have completed prior STI or HIV testing or had a prior STI diagnosis, compared to those who did not. We identified 16 new HIV diagnoses, 2 of which were among repeat testers. Our results suggest that HIV self-testing can be useful to help meet UNAIDS targets to identify undiagnosed infections; however, such efforts are less likely to be successful without adequate linkage to follow-up services, including HIV treatment and prevention care.

Self-tests for COVID-19: What is the evidence? A living systematic review and meta-analysis (2020-2023).

COVID-19 self-testing strategy (COVIDST) can rapidly identify symptomatic and asymptomatic SARS-CoV-2-infected individuals and their contacts, potentially reducing transmission. In this living systematic review, we evaluated the evidence for real-world COVIDST performance. Two independent reviewers searched six databases (PubMed, Embase, Web of Science, World Health Organization database, Cochrane COVID-19 registry, Europe PMC) for the period April 1st, 2020, to January 18th, 2023. Data on studies evaluating COVIDST against laboratory-based conventional testing and reported on diagnostic accuracy, feasibility, acceptability, impact, and qualitative outcomes were abstracted. Bivariate random effects meta-analyses of COVIDST accuracy were performed (n = 14). Subgroup analyses (by sampling site, symptomatic/asymptomatic infection, supervised/unsupervised strategy, with/without digital supports) were conducted. Data from 70 included studies, conducted across 25 countries with a median sample size of 817 (range: 28-784,707) were pooled. Specificity and DOR was high overall, irrespective of subgroups (98.37-99.71%). Highest sensitivities were reported for: a) symptomatic individuals (73.91%, 95%CI: 68.41-78.75%; n = 9), b) mid-turbinate nasal samples (77.79%, 95%CI: 56.03-90.59%; n = 14), c) supervised strategy (86.67%, 95%CI: 59.64-96.62%; n = 13), and d) use of digital interventions (70.15%, 95%CI: 50.18-84.63%; n = 14). Lower sensitivity was attributed to absence of symptoms, errors in test conduct and absence of supervision or a digital support. We found no difference in COVIDST sensitivity between delta and omicron pre-dominant period. Digital supports increased confidence in COVIDST reporting and interpretation (n = 16). Overall acceptability was 91.0-98.7% (n = 2) with lower acceptability reported for daily self-testing (39.5-51.1%). Overall feasibility was 69.0-100.0% (n = 5) with lower feasibility (35.9-64.6%) for serial self-testing. COVIDST decreased closures in school, workplace, and social events (n = 4). COVIDST is an effective rapid screening strategy for home-, workplace- or school-based screening, for symptomatic persons, and for preventing transmission during outbreaks. These data will guide COVIDST policy. Our review demonstrates that COVIDST has paved the way for self-testing in pandemics worldwide.

Real world outcomes of distributing Lucira Check-It® COVID self-tests in Ontario, Canada: the GetaKit COVID study.

BACKGROUND: In Ontario, Canada we developed and implemented an online screening algorithm for the distribution of HIV self-tests, known as GetaKit. During the COVID pandemic, we adapted the GetaKit algorithm to screen for COVID based on population and infection data and distributed COVID rt-LAMP self-tests (using the Lucira Check-It®) to eligible participants. METHODS: GetaKit/COVID was a prospective observational study that occurred over a 7-month period from September 2021 to April 2022. All potential participants completed an online registration and risk assessment, including demographic information, COVID symptoms and risk factors, and vaccination status. Bivariate comparisons were performed for three outcomes: results reporting status, vaccination status, and COVID diagnosis status. Data were analysed using Chi-Square for categorial covariates and Independent Samples T-Test and Mann-Whitney U test for continuous covariates. Bivariate logistic regression models were applied to examine associations between the covariates and outcomes. RESULTS: During the study period, we distributed 6469 COVID self-tests to 4160 eligible participants; 46% identified as Black, Indigenous or a Person of Colour (BIPOC). Nearly 70% of participants reported their COVID self-test results; 304 of which were positive. Overall, 91% also reported being vaccinated against COVID. Statistical analysis found living with five or fewer people, having tested for COVID previously, and being fully vaccinated were positive factors in results reporting. For COVID vaccination, people from large urban centers, who identified their ethnicity as white, and who reported previous COVID testing were more likely to be fully vaccinated. Finally, being identified as a contact of someone who had tested positive for COVID and the presence of COVID-related symptoms were found to be positive factors in diagnosis. CONCLUSIONS: While most participants who accessed this service were vaccinated against COVID and the majority of diagnoses were identified in participants who had symptoms of, or an exposure to, COVID, our program was able to appropriately link participants to recommended follow-up based on reported risks and results. These findings highlight the utility of online screening algorithms to provide health services, particularly for persons with historical barriers to healthcare access, such as BIPOC or lower-income groups.

Prefusion stabilization of the Hendra and Langya virus F proteins.

Nipah virus (NiV) and Hendra virus (HeV) are pathogenic paramyxoviruses that cause mild-to-severe disease in humans. As members of the Henipavirus genus, NiV and HeV use an attachment (G) glycoprotein and a class I fusion (F) glycoprotein to invade host cells. The F protein rearranges from a metastable prefusion form to an extended postfusion form to facilitate host cell entry. Prefusion NiV F elicits higher neutralizing antibody titers than postfusion NiV F, indicating that stabilization of prefusion F may aid vaccine development. A combination of amino acid substitutions (L104C/I114C, L172F, and S191P) is known to stabilize NiV F in its prefusion conformation, although the extent to which substitutions transfer to other henipavirus F proteins is not known. Here, we perform biophysical and structural studies to investigate the mechanism of prefusion stabilization in F proteins from three henipaviruses: NiV, HeV, and Langya virus (LayV). Three known stabilizing substitutions from NiV F transfer to HeV F and exert similar structural and functional effects. One engineered disulfide bond, located near the fusion peptide, is sufficient to stabilize the prefusion conformations of both HeV F and LayV F. Although LayV F shares low overall sequence identity with NiV F and HeV F, the region around the fusion peptide exhibits high sequence conservation across all henipaviruses. Our findings indicate that substitutions targeting this site of conformational change might be applicable to prefusion stabilization of other henipavirus F proteins and support the use of NiV as a prototypical pathogen for henipavirus vaccine antigen design.IMPORTANCEPathogenic henipaviruses such as Nipah virus (NiV) and Hendra virus (HeV) cause respiratory symptoms, with severe cases resulting in encephalitis, seizures, and coma. The work described here shows that the NiV and HeV fusion (F) proteins share common structural features with the F protein from an emerging henipavirus, Langya virus (LayV). Sequence alignment alone was sufficient to predict which known prefusion-stabilizing amino acid substitutions from NiV F would stabilize the prefusion conformations of HeV F and LayV F. This work also reveals an unexpected oligomeric interface shared by prefusion HeV F and NiV F. Together, these advances lay a foundation for future antigen design targeting henipavirus F proteins. In this way, Nipah virus can serve as a prototypical pathogen for the development of protective vaccines and monoclonal antibodies to prepare for potential henipavirus outbreaks.

Cannabis and Driving in Older Adults.

Importance: Epidemiological studies have found that cannabis increases the risk of a motor vehicle collision. Cannabis use is increasing in older adults, but laboratory studies of the association between cannabis and driving in people aged older than 65 years are lacking. Objective: To investigate the association between cannabis, simulated driving, and concurrent blood tetrahydrocannabinol (THC) levels in older adults. Design, Setting, and Participants: Using an ecologically valid counterbalanced design, in this cohort study, regular cannabis users operated a driving simulator before, 30 minutes after, and 180 minutes after smoking their preferred legal cannabis or after resting. This study was conducted in Toronto, Canada, between March and November 2022 with no follow-up period. Data were analyzed from December 2022 to February 2023. Exposures: Most participants chose THC-dominant cannabis with a mean (SD) content of 18.74% (6.12%) THC and 1.46% (3.37%) cannabidiol (CBD). Main outcomes and measures: The primary end point was SD of lateral position (SDLP, or weaving). Secondary outcomes were mean speed (MS), maximum speed, SD of speed, and reaction time. Driving was assessed under both single-task and dual-task (distracted) conditions. Blood THC and metabolites of THC and CBD were also measured at the time of the drives. Results: A total of 31 participants (21 male [68%]; 29 White [94%], 1 Latin American [3%], and 1 mixed race [3%]; mean [SD] age, 68.7 [3.5] years), completed all study procedures. SDLP was increased and MS was decreased at 30 but not 180 minutes after smoking cannabis compared with the control condition in both the single-task (SDLP effect size [ES], 0.30; b = 1.65; 95% CI, 0.37 to 2.93; MS ES, -0.58; b = -2.46; 95% CI, -3.56 to -1.36) and dual-task (SDLP ES, 0.27; b = 1.75; 95% CI, 0.21 to 3.28; MS ES, -0.47; b = -3.15; 95% CI, -5.05 to -1.24) conditions. Blood THC levels were significantly increased at 30 minutes but not 180 minutes. Blood THC was not correlated with SDLP or MS at 30 minutes, and SDLP was not correlated with MS. Subjective ratings remained elevated for 5 hours and participants reported that they were less willing to drive at 3 hours after smoking. Conclusions and relevance: In this cohort study, the findings suggested that older drivers should exercise caution after smoking cannabis.

Lefebvre's production of space: Implications for nursing.

In this paper, we argue that nurses need to be aware of how the production of space in specific contexts - including health care systems and research institutions - perpetuates marginalized populations' state of social otherness. Lefebvre's idea regarding spatial triad is mobilized in this paper, as it pertains to two-spirited, lesbian, gay, bisexual, trans and queer populations (2SLGBTQ*). We believe that nurses can create counter-spaces within health care systems and research institutions that challenge normative discourses. Lefebvre's work provides us the necessary tools to understand how various places or environments produce identities. In understanding Lefebvre's principles, we believe that nurses can play an essential role in creating counter-spaces, thereby instigating counter-institutional practices, for those who experience otherness.

Multiple, active-offer referrals for HIV pre-exposure prophylaxis by nurses yields high uptake among gay, bisexual, and other men who have sex with men.

INTRODUCTION: Current Canadian guidelines focus on indications and uptake of preexposure prophylaxis (PrEP) among groups at-risk for HIV, such as gay, bisexual, and men who have sex with men (GBM). Less, however, is known about the outcomes of PrEP offers. This study presents on the responses of GBM to multiple offers for PrEP. METHODS: In Ottawa, Canada, we instituted Canada's first nurse-led PrEP program, pre-exposure prophylaxis by nurses (PrEP-RN), where nurses offered PrEP referrals to persons with indicators for HIV. Responses to offers from nurses and HIV diagnoses were recorded and assessed for multiple occurrences based on responses. Descriptive analyses were used to report frequencies and percentages of findings and chi-square analyses were conducted to determine significance based on HIV risk for those who accepted versus declined PrEP. RESULTS: Over a 4-year period, 644 PrEP offers were made to 236 unique patients, all of whom were GMB, the majority of whom identified as male. Of the eligible patients, 50.8% accepted and 50.0% declined after multiple offers. Seven trajectories were identified in terms of reasons for accepting or declining PrEP. PrEP referrals made based on clinical guidelines and to those who had changes in risk factors over time were significantly correlated with PrEP acceptance. We noted five HIV diagnoses, all of which were among GBM who declined PrEP at least once. CONCLUSIONS: Based on these findings, it appears multiple PrEP may yield increased PrEP acceptance among a sample of GBM.

The experiences of people who use injection drugs with accessing hepatitis c testing and diagnosis in western countries: A scoping review.

BACKGROUND: The purpose of this scoping review was to summarize the literature that reported on the experiences of people who use injection drugs' access to hepatitis C testing and diagnosis in Western countries. METHODS: The initial search was conducted in 2020 and an updated review was completed in 2022. Seven electronic databases were searched using a peer-reviewed search strategy and included: full-text, peer-reviewed studies with people who inject(ed) drugs, hepatitis C testing or diagnosis, conducted in Western countries. Excluded were studies published prior to 2014 and intervention studies. Two-step screening was conducted in duplicate. Conventional content analysis was used. RESULTS: Six studies were found from the search. The studies were published between 2014 and 2021 in Australia, United Kingdom, and United States. A total of 19 participant characteristics were extracted to contextualize their experiences, demonstrating a lack of demographic data. Four themes were found: Awareness and Knowledge, Stigma, Healthcare Service, and Psychological Responses. There were 58 occurrences of client quotes where participants described their experiences, 29 occurrences of quotes describing client-identified barriers, and 14 occurrences of quotes describing client-identified facilitators. CONCLUSION: A scoping review was conducted to present the experiences, barriers, and facilitators of people who use injection drugs to hepatitis C testing. The lack of demographic data and connection to client quotes further exacerbates the inequities among the population by overlooking their intragroup identities. Understanding their experiences of accessing hepatitis C testing and collecting demographic data will help advance health policies and interventions targeting people who use injection drugs.

Criminal Code reform of HIV non-disclosure is urgently needed: Social science perspectives on the harms of HIV criminalization in Canada.

The criminalization of HIV non-disclosure represents a significant issue of concern among people living with HIV, those working across the HIV sector, public health practitioners, and health and human rights advocates around the world. Recently, the government of Canada began a review of the criminal law regarding HIV non-disclosure and invited feedback from the public about potential reforms to the Criminal Code. In light of this public consultation, this commentary examines social science research from Canadian scholars that documents the intersecting damaging effects of HIV criminalization. Canadian social scientists and other researchers have shown that HIV criminalization is applied in uneven and discriminatory ways, impedes HIV prevention efforts, perpetuates HIV stigma, and has a damaging impact on the daily lives of people living with HIV. We argue that there is an urgent need for reforms that will significantly restrict how the criminal law is applied to HIV non-disclosure.

RéSUMé: La criminalisation de la non-divulgation du VIH est une question très préoccupante pour les personnes vivant avec le VIH, celles qui travaillent dans le secteur du VIH, les praticiens et praticiennes de la santé publique et les porte-parole de la santé et des droits de la personne du monde entier. Récemment, le gouvernement du Canada a amorcé un examen du droit criminel portant sur la non-divulgation du VIH et a invité le public à commenter d'éventuelles réformes du Code criminel. À la lumière de cette consultation publique, notre commentaire porte sur les études en sciences sociales menées au Canada qui font état des effets croisés préjudiciables de la criminalisation du VIH. Des spécialistes des sciences sociales et d'autres chercheuses et chercheurs canadiens ont montré que la criminalisation du VIH est appliquée de façon inégale et discriminatoire, qu'elle nuit aux efforts de prévention du VIH, qu'elle perpétue la stigmatisation liée au VIH et qu'elle a des effets dommageables sur la vie quotidienne des personnes vivant avec le VIH. Nous soutenons qu'il existe un besoin urgent de réformes pour restreindre de façon appréciable l'application du droit criminel à la non-divulgation du VIH.

Clinical features, evaluation, and management of ophthalmic complications of facial paralysis: A review.

The purpose of this review was to study the evaluation, diagnosis, and management of ophthalmic complications associated with facial nerve palsy and to discuss the current and future interventions. The ophthalmic complications of facial paralysis include lagophthalmos, ectropion, exposure keratopathy, ocular synkinesis, and crocodile tears. Evaluation by an ophthalmologist skilled in recognizing and managing complications of facial paralysis shortly after its initial diagnosis can help identify and prevent long-term complications. Several types of grading scales are used to evaluate, measure the severity, and track surgical and patient-reported treatment outcomes. Lagophthalmos or ectropion are managed using temporary measures aimed at lubricating and covering the eye, including scleral lenses; however, these measures can be expensive and challenging to acquire and maintain. Temporary surgical interventions include lateral tarsorrhaphy, weighted eyelid implants, lateral canthoplasty, and other procedures that tighten or lift the eyelid or surrounding tissues. Management of flaccid facial paralysis due to iatrogenic injury or neoplasm requires neurorrhaphy or graft repair. The most common techniques for dynamic reconstruction in chronic facial paralysis are regional and free muscle flap transfer. Future directions for the management of ophthalmic complications aim to induce blinking and eye closure by developing systems that can detect blinking in the normal eye and transmit the signal to the paralyzed eye using mechanisms that would stimulate the muscles to induce eyelid closure. Blink detection technology has been developed, and a study demonstrated that blinking can be stimulated using electrodes on the zygomatic branch of the facial nerve. Further studies are needed to develop a system that will automate blinking and synchronize it with that of the normal eye.

Clinical application of physical therapy in facial paralysis treatment: A review.

This review aims to summarize recent studies regarding the specific modalities of physical therapy as a form of treatment for patients with facial paralysis, analyze the different components of physical therapy, and provide healthcare providers with guidance for their best practice in treating patients with facial paralysis. This paper will discuss the mechanism, indications, and impact factors for facial retraining, evaluate the standards for facial retraining, the creation of a treatment plan, and analyze the combined use of facial retraining with botulinum toxin injections and the application of facial retraining in post facial reanimation patients. Other modes of physical therapy, including electrical stimulation, dry needling, and acupuncture, will be addressed. Lastly, the application of new digital technology will be discussed.

Genome-Wide Association Study and Genomic Prediction of Fusarium Wilt Resistance in Common Bean Core Collection.

The common bean (Phaseolus vulgaris L.) is a globally cultivated leguminous crop. Fusarium wilt (FW), caused by Fusarium oxysporum f. sp. phaseoli (Fop), is a significant disease leading to substantial yield loss in common beans. Disease-resistant cultivars are recommended to counteract this. The objective of this investigation was to identify single nucleotide polymorphism (SNP) markers associated with FW resistance and to pinpoint potential resistant common bean accessions within a core collection, utilizing a panel of 157 accessions through the Genome-wide association study (GWAS) approach with TASSEL 5 and GAPIT 3. Phenotypes for Fop race 1 and race 4 were matched with genotypic data from 4740 SNPs of BARCBean6K_3 Infinium Bea Chips. After ranking the 157-accession panel and revealing 21 Fusarium wilt-resistant accessions, the GWAS pinpointed 16 SNPs on chromosomes Pv04, Pv05, Pv07, Pv8, and Pv09 linked to Fop race 1 resistance, 23 SNPs on chromosomes Pv03, Pv04, Pv05, Pv07, Pv09, Pv10, and Pv11 associated with Fop race 4 resistance, and 7 SNPs on chromosomes Pv04 and Pv09 correlated with both Fop race 1 and race 4 resistances. Furthermore, within a 30 kb flanking region of these associated SNPs, a total of 17 candidate genes were identified. Some of these genes were annotated as classical disease resistance protein/enzymes, including NB-ARC domain proteins, Leucine-rich repeat protein kinase family proteins, zinc finger family proteins, P-loopcontaining nucleoside triphosphate hydrolase superfamily, etc. Genomic prediction (GP) accuracy for Fop race resistances ranged from 0.26 to 0.55. This study advanced common bean genetic enhancement through marker-assisted selection (MAS) and genomic selection (GS) strategies, paving the way for improved Fop resistance.

Patient perspectives on the role of nurses in HIV pre-exposure prophylaxis care (PrEP-RN).

INTRODUCTION: In response to ongoing new HIV diagnoses among gay, bisexual, and other men who have sex with men (gbMSM) and limited access points for HIV pre-exposure prophylaxis (PrEP) care, we established Canada's first nurse-led HIV prevention service in Ottawa, Canada-PrEP-RN. As part of this service, registered nurses became the primary provider in PrEP delivery and monitoring. OBJECTIVES: To (1) gather patients' sentiments and experiences related to nurse-led PrEP and (2) identify the implications for nurses working in sexual healthcare. METHODOLOGY: Qualitative interviews were conducted with 14 gbMSM participants who had received, or were presently enrolled in, HIV prevention care from nurses in the PrEP-RN clinic. Interview transcripts were reviewed and analyzed using thematic analysis. RESULTS: Our analysis revealed two major themes of: The Sexual Health Nurse as the Expert and Patients Reliance on Nurses. The first theme discussed patients' positive attitudes toward nurses, in terms of the knowledge nurses possessed and the kind and efficient services they. The accommodating nature of nurses, however, led patients to become dependent on their care, which was the focus of the second theme. This reliance on nurses created challenges when patients transitioned from PrEP-RN to alternate providers for ongoing care. CONCLUSION: These findings were examined to understand the effect of patients' perceptions of nurses on nursing practice. Despite patients' confidence in nurses' ability to provide PrEP care, the expectations they placed onto nurses to address the totality of their needs created competing demands for nurses to be both a leader in HIV prevention care-and fulfill the image of the caring, healthcare 'hero', which created feelings of moral distress among nurses. As increasing initiatives focus on task-shifting of healthcare roles to nurses, understanding the patients' perspective is essential in maintaining effective nurse-patient relationships.

Clinical outcomes following intraoperative pedicle disruption in fibula free flaps.

OBJECTIVES: Iatrogenic injury of the fibula free flap pedicle is rare. Postoperative flap survival and reconstructive outcomes following intraoperative pedicle severance are unknown. This study assesses free flap outcomes following accidental severance of the peroneal vessels. METHODS: Multi-institutional retrospective chart review from 2000 to 2020. RESULTS: Of 2975 harvested fibula free flaps, 26 had a history of pedicle severance during surgical reconstruction. Reasons for intraoperative pedicle severance included transection during muscular dissection 10/26 (39%), accidental severance with the bone saw 12/26 (46%), and other 4/26 (15.6%). The surgeon responsible for pedicle severance included residents 5/26 (19%), fellows 10/26 (39%), attendings 10/26 (39%), and unknown 1/26 (3.9%). The pedicle artery and vein were severed 10/26 (39%), artery 8/26 (31%), and vein 8/26 (31%). Truncated pedicle vessels were used 3/26 (11.7%), intraoperative anastomoses were performed 23/26 (89%). Postoperative revision in the OR within 7 days of surgery was required 6/26 (23%); 4 flaps were salvaged and 2 flaps failed, both arterial thrombosis. Flap failure was attributed to vascular thrombosis. Long-term flap survival and successful reconstructions were reported 24/26 (92%). CONCLUSION: Accidental severance of fibula free flap pedicle vessels can be corrected with intraoperative repair, without affecting long-term flap survival or reconstructive outcomes. Protecting the flap vessels while using the bone saw and during intramuscular dissection prevents accidental severance.
