The role of the genital microbiota in the acquisition and pathogenesis of sexually transmitted infections.

PURPOSE OF REVIEW: There are an estimated 374 million new sexually transmitted infections (STIs) worldwide every year. Our review article examines the current evidence of how STI acquisition, transmission, and pathogenesis is impacted upon by the genital microbiota, with a focus on epidemiological, biochemical, and immunological features. RECENT FINDINGS: At least in women, a genital microbiota dominated by lactobacilli has long been considered optimal for reproductive health, while depletion of lactobacilli may lead to a genital microenvironment dominated by anaerobic pathogens, which can manifest clinically as bacterial vaginosis. Recent research efforts have characterized genital microbiota composition in greater resolution, sometimes at species-level, using proteomics, metabolomics, and deep sequencing. This has enhanced our understanding of how specific microbiota members influence acquisition or clinical manifestation of STI pathogen infection. Other advances include a steady, though still slow, increase in the number of studies that sought to determine the genital (penile or urethral) microbiota of males and how it may impact that of their female partners' genital microbiota and risk of STI acquisition. Altogether, these data enabled us to explore the concept that genital microbiota may be sexually transmitted and influence pathogenesis and clinical presentation of other STI. SUMMARY: With STI infection rates increasing worldwide, it is important now more than ever to find novel STI prevention strategies. Understanding if and how the genital microbiota is a modifiable risk factor for STI transmission, acquisition, and clinical manifestation may prove to be an important strategy in our efforts to curb morbidity in at risk populations.

Meta-analysis of primary care delivered buprenorphine treatment retention outcomes.

Background: Currently, the capacity to provide buprenorphine treatment (BT) is not sufficient to treat the growing number of people in the United States with opioid use disorder (OUD). We sought to examine participant retention in care rates of primary care delivered BT programs and to describe factors associated with retention/attrition for participants receiving BT in this setting.Objectives: A PRISMA-guided search of various databases was performed to identify the articles focusing on efficacy of BT treatment and OUD.Method: A systematic literature search identified 15 studies examining retention in care in the primary care setting between 2002 and 2020. Random effects meta-regression were used to identify retention rates across studies.Results: Retention rates decreased across time with a mean 0.52 rate at one year. Several factors were found to be related to retention, including: race, use of other drugs, receipt of counseling, and previous treatment with buprenorphine.Conclusions: While we only investigate BT through primary care, our findings indicate retention rates are equivalent to the rates reported in the specialty care literature. More work is needed to examine factors that may impact primary care delivered BT specifically and differentiate participants that may benefit from care delivered in specialty over primary care as well as the converse.

Simulations using telehealth to collaborate with other health-care professionals: effect on pre-licensure nursing students' competencies and amount of collaboration in the clinical setting.

Nursing students must gain experience collaborating with other members of the health-care team. Simulation can provide intra- and interprofessional collaboration experience; however, there can be barriers such as scheduling difficulties. We evaluated multi-patient, standardized patient simulations using telehealth as a strategy to provide baccalaureate nursing students with opportunities to learn and practice intra- and interprofessional collaboration. Forty-four final-semester nursing students participated. Student groups rotated to the simulation laboratory over 12 weeks to participate in two simulations that used telehealth to enable them to communicate patient concerns to other clinicians: a nurse practitioner, respiratory therapists, and social workers. Self-reported collaborative competencies and amount of collaboration in the clinical setting were measured at the start and end of the semester. Satisfaction and self-confidence were measured immediately after each simulation. For collaborative competencies, there was a statistically significant improvement in all item, subscale, and overall scale mean scores. Amount of clinical collaboration significantly improved, with the amount who indicated they never reported a patient concern to another professional decreasing from 39.5% to 6.8%. Findings also revealed a high level of student satisfaction and self-confidence following the simulations. Using telehealth to collaborate during simulations is a promising strategy to prepare nursing students for practice by improving collaborative competencies and encouraging more collaboration in the clinical setting.

Increasing Nursing Students' Knowledge of Autism Spectrum Disorder by Using a Standardized Patient.

Nursing students participated in a simulation using a standardized patient role-playing an adolescent with autism spectrum disorder (ASD). The researchers used student feedback to develop and improve a simulation aimed at increasing learner skills and knowledge for treating ASD patients. Students indicated that the standardized patient provided realism not obtained when using static manikins or high-fidelity simulators. Students strongly agreed or agreed that classroom instruction prior to the simulation was important to increasing their knowledge of ASD. Overall, the simulation provided students an opportunity to practice and develop their clinical skills in caring for patients with ASD.

Strategies for Successful Nurse-Student Preceptorships.

Being a preceptor for a new nurse or a student is a great way to promote the future of nursing. However, most nurses have not been taught how to be an effective preceptor. Eight strategies for effective precepting are presented. Servant leadership is discussed as a theoretical basis for serving as a preceptor.

Treat students as potential employees.

In today's complex, chaotic, and rapidly changing healthcare environment, a newly registered nurse will face many obstacles on the journey into a professional role.

Developing a Research Agenda on Resident-to-Resident Aggression: Recommendations From a Consensus Conference.

This article provides an overview of the development of a research agenda on resident-to-resident aggression (RRA) in long-term care facilities by an expert panel of researchers and practitioners. A 1-day consensus-building workshop using a modified Delphi approach was held to gain consensus on nomenclature and an operational definition for RRA, to identify RRA research priorities, and to develop a roadmap for future research on these priorities. Among the six identified terms in the literature, RRA was selected. The top five priorities were: (a) developing/assessing RRA environmental interventions; (b) identification of the environmental factors triggering RRA; (c) incidence/prevalence of RRA; (d) developing/assessing staff RRA education interventions; and (e) identification of RRA perpetrator and victim characteristics. Given the significant harm RRA poses for long-term care residents, this meeting is an important milestone, as it is the first organized effort to mobilize knowledge on this under-studied topic at the research, clinical, and policy levels.

Native American ancestry affects the risk for gene methylation in the lungs of Hispanic smokers from New Mexico.

RATIONALE: Gene promoter methylation detected in sputum predicts lung cancer risk in smokers. Compared with non-Hispanic whites (NHW), Hispanics have a lower age-standardized incidence for lung cancer. OBJECTIVES: This study compared the methylation prevalence in sputum of NHWs with Hispanics using the Lovelace Smokers cohort (n = 1998) and evaluated the effect of Native American ancestry (NAA) and diet on biomarkers for lung cancer risk. METHODS: Genetic ancestry was estimated using 48 ancestry markers. Diet was assessed by the Harvard University Dietary Assessment questionnaire. Methylation of 12 genes was measured in sputum using methylation-specific polymerase chain reaction. The association between NAA and risk for methylation was assessed using generalized estimating equations. The ethnic difference in the association between pack-years and risk for lung cancer was assessed in the New Mexico lung cancer study. MEASUREMENTS AND MAIN RESULTS: Overall Hispanics had a significantly increased risk for methylation across the 12 genes analyzed (odds ratio, 1.18; P = 0.007). However, the risk was reduced by 32% (P = 0.032) in Hispanics with high versus low NAA. In the New Mexico lung cancer study, Hispanic non-small cell lung cancer cases have significantly lower pack-years than NHW counterparts (P = 0.007). Furthermore, compared with NHW smokers, Hispanic smokers had a more rapidly increasing risk for lung cancer as a function of pack-years (P = 0.058). CONCLUSIONS: NAA may be an important risk modifier for methylation in Hispanic smokers. Smoking intensity may have a greater impact on risk for lung cancer in Hispanics compared with NHWs.

Genetic variation in SIRT1 affects susceptibility of lung squamous cell carcinomas in former uranium miners from the Colorado plateau.

Epidemiological studies of underground miners suggested that occupational exposure to radon causes lung cancer with squamous cell carcinoma (SCC) as the predominant histological type. However, the genetic determinants for susceptibility of radon-induced SCC in miners are unclear. Double-strand breaks induced by radioactive radon daughters are repaired primarily by non-homologous end joining (NHEJ) that is accompanied by the dynamic changes in surrounding chromatin, including nucleosome repositioning and histone modifications. Thus, a molecular epidemiological study was conducted to assess whether genetic variation in 16 genes involved in NHEJ and related histone modification affected susceptibility for SCC in radon-exposed former miners (267 SCC cases and 383 controls) from the Colorado plateau. A global association between genetic variation in the haplotype block where SIRT1 resides and the risk for SCC in miners (P = 0.003) was identified. Haplotype alleles tagged by the A allele of SIRT1 rs7097008 were associated with increased risk for SCC (odds ratio = 1.69, P = 8.2 × 10(-5)) and greater survival in SCC cases (hazard ratio = 0.79, P = 0.03) in miners. Functional validation of rs7097008 demonstrated that the A allele was associated with reduced gene expression in bronchial epithelial cells and compromised DNA repair capacity in peripheral lymphocytes. Together, these findings substantiate genetic variation in SIRT1 as a risk modifier for developing SCC in miners and suggest that SIRT1 may also play a tumor suppressor role in radon-induced cancer in miners.

Elder abuse through a life course lens.

BACKGROUND: This paper provides the findings from a large pilot study, Defining and Measuring Elder Abuse and Neglect, a precursor to a national prevalence study to be conducted in Canada beginning in September 2013. One purpose of this study and the focus of this paper was to determine whether a life course perspective would provide a useful framework for examining elder abuse. The two-year pilot study, 2009-2011, examined the prevalence of perceptions of abuse at each life stage by type of abuse, the importance of early life stage abuse in predicting types of elder abuse, and early life stage abuse as a risk factor for elder abuse. METHODS: Older adults who were aged ≥55 years (N = 267) completed a cross-sectional telephone survey, comprising measures of five types of elder abuse (neglect, physical, sexual, psychological, and financial) and their occurrence across the life course: childhood (≤17 years), young adulthood (18 to 24 years), and older adulthood (5 to 12 months prior to the interview date). Data analyses included descriptive statistics, bivariate correlations for abuse at the various life stages, and the estimation of logistic regression models that examined predictors of late life abuse, and multinomial logistic regression models predicting the frequency of abuse. RESULTS: Fifty-five percent of the sample reported abuse during childhood, and 34.1% reported abuse during young adulthood. Forty-three percent said they were abused during mature adulthood, and 24.4% said they were abused since age 55 but prior to the interview date of the study. Psychological (42.3%), physical (26.6%), and sexual abuses (32.2%) were the most common abuses in childhood while psychological abuse was the most common type of abuse at each life stage. When the risk factors for abuse were considered simultaneously including abuse during all three life stages, only a history of abuse during childhood retained its importance (OR = 1.81, p = 0.046, CI = 1.01-3.26). Abuse in childhood increased the risk of experiencing one type of abuse relative to no abuse, but was also unrelated to experiencing two or more types of abuse compared to no abuse. CONCLUSIONS: Results suggest that a life course perspective provides a useful framework for understanding elder abuse and neglect. The findings indicate that a childhood history of abuse in this sample had a deciding influence on later mistreatment, over and above what happens later in life.

Students and simulation facilitators' experiences and perceptions of a distraction and interruption simulation: a mixed-methods study.

BACKGROUND: While distractions and interruptions are leading causes of errors during medication preparation, most nursing students are not taught how to manage distractions in a highly-interruptive environment. To help prepare nursing students to manage distractions and interruptions in clinical practice, we developed, implemented, and evaluated a medication preparation distraction and interruption simulation. OBJECTIVES: To explore student and simulation facilitators experiences and perceptions of a distraction and interruption simulation. DESIGN: A sequential explanatory mixed-methods design was adopted including surveys, interviews, and focus groups. SETTING: A mid-sized research intensive western Canadian university. PARTICIPANTS: A total of 112 third year nursing students who engaged in the distraction and interruption simulation, and five simulation facilitators who facilitated the distraction and interruption simulation, participated in this study. METHODS: Students were invited to complete a cross sectional survey following the distraction and interruption simulation and were then invited to participate in focus groups. Simulation facilitators were invited to participate in one-on-one interviews following facilitating the distraction and interruption simulation. All data were collected between June and December 2020. RESULTS: Data from surveys, interviews, and focus groups were delineated into 4 themes related to the phases of the simulation. The prebriefing provided an overview of the simulation and helped create psychological safety that was imperative for learning about potential medication errors when being distracted and interrupted. The simulation scenario had a high degree of fidelity and helped students implement strategies to manage distractions and interruptions. The structured debrief provided an opportunity for meaningful reflection. The impact of the simulation was apparent as students articulated the balance between speed versus safety and new strategies developed to manage distractions and interruptions in clinical practice. CONCLUSION: This study supports the use of simulation to develop key skills for managing distractions and interruptions during medication preparation in clinical practice.

Management of Otogenic Sigmoid Sinus Thrombosis: A Systematic Review on the Role of Anticoagulation and its Outcome.

To provide a systematic review on the use of additional anticoagulation in the management of otogenic sigmoid sinus thrombosis when compared with the cohort not receiving the anticoagulation. A systematic review until 2021 was done and relevant studies were screened. Based on a selective criteria, a database is constituted which were then rearranged and studied. 16 articles were selected with 113 patients. The group who received anticoagulation had more complications (23.33%) in comparison (21.74%), whereas the recanalization was successful in the anticoagulated group, 76.67%, as against 39.13%. In 74/90 patients who underwent mastoidectomy with anticoagulation, the recanalization and complication were 72.97% and 25.68% respectively. The second group with 16/90 patients who received conservative treatment, the recanalization and complication rates were 93.75% and 12.50% respectively. The third group with 23 patients were treated with mastoidectomy and antibiotics but didn't receive anticoagulants in which the recanalization achieved in 39.13% with a complication rate of 21.74%. For those patients who underwent mastoidectomy with concurrent anticoagulation, 44 showed radiological evidence of recanalization, and in sixteen patients that received the same treatment, no recanalization was achieved whereas in patients who received conservative treatment with anticoagulation, 12 patients showed recanalization and finally, for the patients underwent surgery without anticoagulation, five patients achieved recanalization and 7 did not become recanalized (14.29%). Recanalization seems more pronounced in those who were anticoagulated, but, did not seem to influence the clinical outcome. Complications were more in those who were undergone surgery with or without anticoagulation.

Central quadrantotomy for intractable childhood epilepsy: operative technique and functional neuroanatomy.

Refractory subhemispheric epilepsy has been traditionally treated by resection. The last few decades have seen the emergence of disconnective techniques, for both hemispheric and subhemispheric disease. The aim of this study was to describe the technique for a disconnective surgery for large epileptogenic lesions involving the central (perirolandic cortices), parietal, and occipital lobes. This junctional cortex within the hemisphere (in contrast to anterior and posterior quadrantotomies) presents unique challenges when contemplating a complete disconnection of the region. The surgical technique is achieved through six distinct steps: fronto-central, inferior frontoparietal, lateral temporo-occipital, medial frontal, basal temporo-occipital, and posterior parasagittal callosal disconnections. The functional neuroanatomy of each step is described, along with cadaveric dissections. The authors describe this technique and include a case description of a young girl who presented with childhood-onset intractable epilepsy associated with cognitive stagnation. The postoperative seizure outcome in this patient remains excellent at 2 years' follow-up, with gains in cognition and behavior. Excellent seizure outcomes can be achieved if the network encompassing the entire epileptogenic cortex is disconnected while ensuring preservation of fiber systems that link functionally eloquent uninvolved cortices adjacent to the central quadrant.

The transition from student to new registered nurse in professional practice.

This qualitative study presents the transition experience of new registered nurses during the first year of professional practice. Four themes emerged: feelings of frustration and being overwhelmed, preceptors, fear, and the orientation process. The orientation process, quality, competent preceptors, and reducing lateral violence are key strategies to successfully retain new nurses. Nurse educators have a crucial role during nurse orientation, training preceptors, and reducing violent behaviors in the workplace.

School nurse and COVID-19 response.

The role of the school nurse should not be understated when addressing the Covid-19 pandemic and its effects on children and families. Knowledge surrounding this virus is rapidly changing and quick adaptation within the school system is required. In addition to the provision of direct care and education to students, school nurse responsibilities include the development and implementation of new policies; consideration of social and emotional well-being; and effective communication with students, families, teachers, administrators, and community stakeholders. This article addresses current evidence related to the coronavirus disease 2019 (COVID-19) pandemic and the evolving role of the school nurse. A case study incorporates tips and suggestions for school nurses who will deliver professional care during this COVID-19 crisis.

Cadaveric White Matter Dissection Study of the Telencephalic Flexure: Surgical Implications.

Neurosurgery has traditionally been overtly focused on the study of anatomy and functions of cortical areas with microsurgical techniques aimed at preserving eloquent cortices. In the last two decades, there has been ever-increasing data emerging from advances in neuroimaging (principally diffusion tensor imaging) and clinical studies (principally from awake surgeries) that point to the important contribution of white matter tracts (WMT) that influence neurological function as part of a brain network. Major scientific consortiums worldwide, currently working on this human brain connectome, are providing evidence that is dramatically altering the manner in which we view neurosurgical procedures. The development of the telencephalic flexure, a major landmark during the human embryogenesis of the central nervous system (CNS), severely affects the cortical/subcortical anatomy in and around the sylvian fissure and thus the different interacting brain networks. Indeed, the telencephalic flexure modifies the anatomy of the human brain with the more posterior areas becoming ventral and lateral and associative fibers connecting the anterior areas with the previous posterior ones follow the flexure, thus becoming semicircular. In these areas, the projection, association, and commissural fibers intermingle with some WMT remaining curved and others longitudinal. Essentially the ultimate shape and location of these tracts are determined by the development of the telencephalic flexure. Five adult human brains were dissected (medial to lateral and lateral to medial) with a view to describing this intricate anatomy. To better understand the 3D orientation of the WMT of the region we have correlated the cadaveric data with the anatomy presented in the literature of the flexure during human neuro-embryogenesis in addition to cross-species comparisons of the flexure. The precise definition of the connectome of the telencephalic flexure is primordial during glioma surgery and for disconnective epilepsy surgery in this region.

Prospective analysis of DNA damage and repair markers of lung cancer risk from the Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial.

Mutagen challenge and DNA repair assays have been used in case-control studies for nearly three decades to assess human cancer risk. The findings still engender controversy because blood was drawn after cancer diagnosis so the results may be biased, a type called 'reverse causation'. We therefore used Epstein-Barr virus-transformed lymphoblastoid cell lines established from prospectively collected peripheral blood samples to evaluate lung cancer risk in relation to three DNA repair assays: alkaline Comet assay, host cell reactivation (HCR) assay with the mutagen benzo[a]pyrene diol epoxide and the bleomycin mutagen sensitivity assay. Cases (n = 117) were diagnosed with lung cancer between 0.3 and 6 years after blood collection and controls (n = 117) were frequency matched on calendar year and age at blood collection, gender and smoking history; all races were included. Case and control status was unknown to laboratory investigators. In unconditional logistic regression analyses, statistically significantly increased lung cancer odds ratios (OR(adjusted)) were observed for bleomycin mutagen sensitivity as quartiles of chromatid breaks/cell [relative to the lowest quartile, OR = 1.2, 95% confidence interval (CI): 0.5-2.5; OR = 1.4, 95% CI: 0.7-3.1; OR = 2.1, 95% CI: 1.0-4.4, respectively, P(trend) = 0.04]. The magnitude of the association between the bleomycin assay and lung cancer risk was modest compared with those reported in previous lung cancer studies but was strengthened when we included only incident cases diagnosed more than a year after blood collection (P(trend) = 0.02), supporting the notion the assay may be a measure of cancer susceptibility. The Comet and HCR assays were unrelated to lung cancer risk.

Teaching nursing students and newly registered nurses strategies to deal with violent behaviors in the professional practice environment.

Direct and indirect violent behaviors toward nursing students and newly registered nurses must be eliminated. Nursing students and newly registered nurses are particularly vulnerable to acts of violence. The article discusses the effect of violence on students and newly registered nurses, the role of the continuing education nurse in eliminating violence, examples of aggressive situations, and strategies to educate and support students and new nurses and empower them to eliminate violence directed toward them. Strategies include confrontation tips, implementation of violence-free contracts, participation in role-play activities, adoption of a professional communication technique, reflection journaling and cognitive recognition, promotion of carefronting, introduction of dialogue through the World Café, and use of nurse preceptors, practice partnerships, residency programs.

Promoting nursing careers using a storybook for children.

Recruitment into the nursing profession is an urgent need. Using the storybook Jill Learns About Nurses Around the Town, 11 nurses participated in a nursing promotion program with elementary-age children. Narrative analysis of participant experiences suggests nurses want to and can effectively participate in nursing promnotion programs with children.

Baccalaureate nursing students' experiences with multi-patient, standardized patient simulations using telehealth to collaborate.

BACKGROUND: Nurse faculty must utilize teaching strategies that promote student achievement of essential competencies, and simulation can provide experiential learning to help prepare students for professional practice. PURPOSE: The purpose of this phenomenological qualitative study was to explore baccalaureate nursing students' experiences with multi-patient, standardized patient simulations that used telehealth to provide opportunities to learn and practice intra- and interprofessional collaboration. Student perceptions of their ability to utilize lessons from the simulations in clinical practice were also examined. METHODS: Focus group interviews were conducted with 27 final-semester baccalaureate nursing students after they had participated in two telehealth-enhanced simulations. RESULTS: Analysis revealed five themes: Anxiety due to lack of experience, Improved clinical reasoning, Real world practice, How to communicate effectively, and Application to clinical practice. CONCLUSION: The use of telehealth helped overcome barriers to implementing collaborative simulations and provided students with experiential learning that addressed essential competencies for safe and effective professional nursing practice.
