Is medical training solely to blame? Generational influences on the mental health of our medical trainees.

INTRODUCTION: The negative impact of medical training on trainee mental health continues to be a concern. Situated within a sociocultural milieu, Generation Z and Generation Y, defined by their highly involved parents and the widespread use of technology, currently dominate undergraduate and graduate medical education respectively. It is necessary to explore medical trainees' generational characteristics and job-related factors related to stress, burnout, depression, and resilience. This might provide different perspectives and potential solutions to medical trainees' mental health. METHODS: A cross-sectional study was conducted among medical trainees (students and residents) from two institutions in Qatar. A self-administered online survey included measures for trainees' social media overuse, their parent's parenting style, the educational support by the clinical teacher, job (demands, control, and support), and work-life balance and their relation with their stress, burnout, depression, and resilience. Relationships were tested with multiple linear regression analyses. RESULTS: Of the 326 medical trainees who responded, 142 (44%) trainees - 93 students and 49 residents - completed all items and were included in the analysis. Social media overuse and inability to maintain a work-life balance were associated with higher levels of stress, depression, and student burnout. Higher levels of job support were associated with lower levels of stress, depression, and resident burnout, and a higher level of resilience. Job control was associated with lower burnout levels. Parenting style was unrelated to trainees' mental health. DISCUSSION: The two generations 'Y' and 'Z' dominating current medical training showed more stress-related complaints when there is evidence of social media overuse and failure to maintain a work-life balance, while job support counterbalances this, whereas parenting style showed no effect. Measures to enhance medical trainees' mental health may include education about the wise use of social media, encouraging spending more quality social time, and enhancing job support and job control.

Reduction of Urinary Tract Infection in Pediatric Surgical Patients Using NSQIP-P and Quality Improvement Methodology.

BACKGROUND: Hospital-acquired urinary tract infections (UTIs) have a detrimental effect on patients, families, and hospital resources. The Sydney Children's Hospital Network (SCHN) participates in the NSQIP-Pediatric (NSQIP-P) to monitor postoperative complications. NSQIP-P data revealed that the median UTI rate at SCHN was 1.75% in 2019, 3.5 times higher than the NSQIP-P target rate of 0.5%. Over three quarters of the NSQIP-P identified patients with UTI also had a urinary catheterization performed intraoperatively. A quality improvement project was conducted between mid-2018 and 2021 to minimize catheter-associated UTIs (CAUTIs) at SCHN. STUDY DESIGN: NSQIP-P samples include pediatric (younger than 18 years) surgical patients from an 8-day cycle operative log. NSQIP-P data are statistically analyzed by the American College of Surgeons and provide biannual internationally benchmarked reports. The project used clinical redesign methodology with a 6-phase process for quality improvement projects. RESULTS: The objectives of the project were to reduce urinary catheter duration of use, educate parents or carers, and improve catheter care and insertion technique by health staff. The duration of a urinary catheter in situ reduced from a median of 4.5 to 3 days from 2017 to 2021. The median NSQIP-P UTI rate at SCHN was reduced by 47.4% from 1.75% in 2019 to 0.9% in 2022. CONCLUSIONS: A multifactorial approach in quality improvement has been shown to be an effective strategy to reduce UTI rates at SCHN, and patient outcomes were improved within a 3-year timeframe. Although this project has reduced UTI rates at SCHN, there remain opportunities for further improvement.

Co-Occurrence of Wing Deformity and Impaired Mobility of Alates with Deformed Wing Virus in Solenopsis invicta Buren (Hymenoptera: Formicidae).

Deformed wing virus (DWV), a major honey bee pathogen, is a generalist insect virus detected in diverse insect phyla, including numerous ant genera. Its clinical symptoms have only been reported in honey bees, bumble bees, and wasps. DWV is a quasispecies virus with three main variants, which, in association with the ectoparasitic mite, Varroa destructor, causes wing deformity, shortened abdomens, neurological impairments, and colony mortality in honey bees. The red imported fire ant, Solenopsis invicta Buren, is one of the most-invasive and detrimental pests in the world. In this study, we report the co-occurrence of DWV-like symptoms in S. invicta and DWV for the first time and provide molecular evidence of viral replication in S. invicta. Some alates in 17 of 23 (74%) lab colonies and 9 of 14 (64%) field colonies displayed deformed wings (DWs), ranging from a single crumpled wing tip to twisted, shriveled wings. Numerous symptomatic alates also exhibited altered locomotion ranging from an altered gait to the inability to walk. Deformed wings may prevent S. invicta alates from reproducing since mating only occurs during a nuptial flight. The results from conventional RT-PCR and Sanger sequencing confirmed the presence of DWV-A, and viral replication of DWV was confirmed using a modified strand-specific RT-PCR. Our results suggest that S. invicta can potentially be an alternative and reservoir host for DWV. However, further research is needed to determine whether DWV is the infectious agent that causes the DW syndrome in S. invicta.

Decreased Cerebrovascular Reactivity in Mild Cognitive Impairment Phenotypes.

BACKGROUND: Cerebrovascular health plays an important role in cognitive health in older adults. Cerebrovascular reactivity (CVR), a measure of cerebrovascular health, changes in both normal and pathological aging, and is increasingly being conceptualized as contributory to cognitive decline. Interrogation of this process will yield new insights into cerebrovascular correlates of cognition and neurodegeneration. OBJECTIVE: The current study examines CVR using advanced MRI in prodromal dementia states (amnestic and non-amnestic mild cognitive impairment phenotypes; aMCI and naMCI, respectively) and older adult controls. METHODS: CVR was assessed in 41 subjects (20 controls, 11 aMCI, 10 naMCI) using multiband multi-echo breath-holding task functional magnetic resonance imaging. Imaging data were preprocessed and analyzed using AFNI. All participants also completed a battery of neuropsychological tests. T-tests and ANOVA/ANCOVA analyses were conducted to compare controls to MCI groups on CVR and cognitive metrics. Partial correlation analyses between CVR derived from regions-of-interest (ROIs) and different cognitive functions were conducted. RESULTS: CVR was found to be significantly lower in aMCI and naMCI patients compared to controls. naMCI showed intermediate patterns between aMCI and controls (though aMCI and naMCI groups did not significantly differ). CVR of ROIs were positively correlated with neuropsychological measures of processing speed, executive functioning, and memory. CONCLUSION: The findings highlight regional CVR differences in MCI phenotypes compared to controls, where aMCI may have lower CVR than naMCI. Our results suggest possible cerebrovascular abnormalities associated with MCI phenotypes.

Complete chromosome-level genome assembly data from the tawny crazy ant, Nylanderia fulva (Mayr) (Hymenoptera: Formicidae).

The tawny crazy ant, Nylanderia fulva (Mayr) (Hymenoptera: Formicidae) has a native range that extends from northern Argentina to southern Brazil. In the U.S.A. this species has often been misidentified as Nylanderia (Paratrechina) pubens or N. cf. pubens and has likely been present in Florida and Texas for several decades [1]. In the early 2000's explosive population growth in Texas and neighboring states drew renewed taxonomic focus. Genetic analyses [2,3] aided in identifying the pest species as N. fulva. This species poses an invasive threat to native flora and fauna and human structures. In its invasive range it has been reported to displace another invasive species, the red imported fire ant. The specimens used for genome sequencing were obtained from the coastal region of Mississippi. DNA was extracted from pupae. The genome data set was deposited to the National Center for Biotechnology Information as submission ID: SUB10775679, Project ID: PRJNA796544, Accession IDs: SAMN24895442 and JAKFQQ000000000. The organism taxid is 613905, locus tag prefixes are L1K79. The assembly, USDA_Nfulva_1.0, was generated in collaboration with Dovetail Genomics (now Cantata Bio) to yield a chromosome-level assembly of 375 Mb with a 15.67 Mb N50 and 78X coverage and revealing 16 putative chromosomes. This high-quality chromosome-level genome assembly was released prior to publication as a public service to the research community.

Sailing the boat together: Co-creation of a model for learning during transition.

PURPOSE: Medical students' transition to postgraduate training, given the complexity of new roles and responsibilities, requires the engagement of all involved stakeholders. This study aims to co-create a transition curriculum and determine the value of involving the key stakeholders throughout such transition in its design process. METHODS: We conducted a mixed-methods study involving faculty/leaders (undergraduate/postgraduate), final-year medical students, and chief residents. It commenced with eight co-creation sessions (CCS), qualitative results of which were used to draft a quantitative survey sent to non-participants, followed by two consensus-building CCS with the original participants. We applied thematic analysis for transcripts of all CCS, and mean scores with standard deviations for survey analysis. RESULTS: We identified five themes: adaptation, authenticity, autonomy, connectedness, and continuity, embedded in the foundation of a supportive environment, to constitute a Model of Learning during Transition (MOLT). Inclusion of various stakeholders and optimizing their representation brought rich perspectives to the design process. This was reinforced through active students' participation enabling a final consensus. CONCLUSIONS: Bringing perspectives of key stakeholders in the transition spectrum enriches transition curricula. The proposed MOLT can provide a guide for curriculum designers to optimize the final year of undergraduate medical training in preparing students for postgraduate training with essential competencies to be trained.

Gross Morphology of Diseased Tissues in Nezara viridula (Hemiptera: Pentatomidae) and Molecular Characterization of an Associated Microsporidian.

Nezara viridula (L.) (Hemiptera: Pentatomidae), commonly known in the U.S. as the southern green stink bug (SGSB), is a cosmopolitan, highly polyphagous feeder that causes severe damage to a wide range of agronomically important crops such as fruit, vegetable, grain, tobacco, and cotton, throughout much of the United States, and is a global pest of considerable ecological, agricultural, and economical interest. During dissection of female Nz. viridula, conspicuous black and brown spots or lesions were observed on various internal organs. To determine the cause of these spots or lesions, tissues of fat body, spermatheca, ovaries, and ovulated eggs were collected from healthy and infected individuals. The gross morphology of the spots was characterized, and the microorganisms associated with the infection were identified by amplicon sequencing of the V4 region of the small subunit rRNA gene. The presence of a microsporidian pathogen Nosema maddoxi, Becnel, Solter, Hajek, Huang, Sanscrainte, & Estep (Microsporidia: Nosematidae) which has been observed on other species of stink bug, was evidenced for the first time. The characterization of the gross morphology of this associated microsporidian may enable more rapid determination of microsporidia infection in stink bug colonies and field populations.

Trypanosomatids Associated in the Alimentary Canal of Bagrada hilaris (Hemiptera: Pentatomidae).

Bagrada hilaris (Burmeister) is an invasive pest of economically important crops in the United States. During physiological investigations of B. hilaris, a flagellated protozoan was discovered in the alimentary canal of many specimens. This manuscript characterizes the morphology and molecular identification of the trypanosomatid, which appears similar to trypanosomatids identified in other stink bug species. It has been identified as a species in the Blastocrithidia genus based on morphological characteristics and molecular analyses.

Ever-increasing viral diversity associated with the red imported fire ant Solenopsis invicta (Formicidae: Hymenoptera).

BACKGROUND: Advances in sequencing and analysis tools have facilitated discovery of many new viruses from invertebrates, including ants. Solenopsis invicta is an invasive ant that has quickly spread worldwide causing significant ecological and economic impacts. Its virome has begun to be characterized pertaining to potential use of viruses as natural enemies. Although the S. invicta virome is the best characterized among ants, most studies have been performed in its native range, with less information from invaded areas. METHODS: Using a metatranscriptome approach, we further identified and molecularly characterized virus sequences associated with S. invicta, in two introduced areas, U.S and Taiwan. The data set used here was obtained from different stages (larvae, pupa, and adults) of S. invicta life cycle. Publicly available RNA sequences from GenBank's Sequence Read Archive were downloaded and de novo assembled using CLC Genomics Workbench 20.0.1. Contigs were compared against the non-redundant protein sequences and those showing similarity to viral sequences were further analyzed. RESULTS: We characterized five putative new viruses associated with S. invicta transcriptomes. Sequence comparisons revealed extensive divergence across ORFs and genomic regions with most of them sharing less than 40% amino acid identity with those closest homologous sequences previously characterized. The first negative-sense single-stranded RNA virus genomic sequences included in the orders Bunyavirales and Mononegavirales are reported. In addition, two positive single-strand virus genome sequences and one single strand DNA virus genome sequence were also identified. While the presence of a putative tenuivirus associated with S. invicta was previously suggested to be a contamination, here we characterized and present strong evidence that Solenopsis invicta virus 14 (SINV-14) is a tenui-like virus that has a long-term association with the ant. Furthermore, based on virus sequence abundance compared to housekeeping genes, phylogenetic relationships, and completeness of viral coding sequences, our results suggest that four of five virus sequences reported, those being SINV-14, SINV-15, SINV-16 and SINV-17, may be associated to viruses actively replicating in the ant S. invicta. CONCLUSIONS: The present study expands our knowledge about viral diversity associated with S. invicta in introduced areas with potential to be used as biological control agents, which will require further biological characterization.

Assessing the Quality of Care Delivered to Transgender and Gender Diverse Patients with Cancer in Ireland: A Case Series.

INTRODUCTION: "Transgender" and "gender diverse" are umbrella terms encompassing those whose gender identities or expressions differ from those typically associated with the sex they were assigned at birth. There is scant global information on cancer incidence, outcome, and mortality for this cohort. This group may present with advanced cancer, have mistrust in health care services and report anxiety and depression at higher frequencies, a finding often seen in marginalized groups because of minority stress. MATERIALS AND METHODS: Medical oncologists were contacted by secure email to identify patients who self-identify as transgender and gender diverse in three Irish hospitals. Five patients were identified. A retrospective chart review was conducted and a pseudonymized patient survey was distributed. RESULTS: All patients included in our chart review (n = 5) were diagnosed with advanced disease on initial diagnosis. Two patients identified as men, two as women, and one as a transwoman. Two of five patients' health record charts reflected a name or gender change. Three patients had gender transitioning treatment postponed. Assessing comorbidities, it was seen that four patients required psychiatry input. Predominant issues noted in our patient survey by the two respondents (n = 2) were "mis-gendering," lack of a gender-neutral hospital environment, lack of inclusion in cancer groups, and barriers in changing name and/or sex on hospital records. CONCLUSION: Components of care requiring revision include patient accessible pathways to change names and gender on health records, earlier access to psychological support and targeted screening and support groups. Resources for hospital staff to improve awareness of correct terminology and to provide gender neutral facilities are worthwhile. IMPLICATIONS FOR PRACTICE: The implications for practice on an international level include patient-friendly pathways for changing hospital name and gender so that patients may feel comfortable using wristbands. The need for international screening guidelines for transgender patients and national transgender cancer support groups is highlighted. On a day-to-day level for providers, the correct use of pronouns makes a big difference to patients. Asking about preferred pronoun on first visit and noting on patient's file is worthwhile. It is important for providers to know that increased psychological support should be offered early on first clinic visit and engaged with as necessary when patient has a history of anxiety or depression. Providers should discuss openly that some gender transitioning treatment will be postponed because of cancer care and refer to both the physical and psychological sequelae of this. Asking transgender patients which room or bathroom they would prefer when rooms are gendered is essential.

Immunotherapy for Infarcts: In Vivo Postinfarction Macrophage Modulation Using Intramyocardial Microparticle Delivery of Map4k4 Small Interfering RNA.

The myeloid cells infiltrating the heart early after acute myocardial infarction elaborate a secretome that largely orchestrates subsequent ventricular wall repair. Regulating this innate immune response could be a means to improve infarct healing. To pilot this concept, we utilized (ß1,3-d-) glucan-encapsulated small interfering RNA (siRNA)-containing particles (GeRPs), targeting mononuclear phagocytes, delivered to mice as a one-time intramyocardial injection immediately after acute infarction. Findings demonstrated that cardiac macrophages phagocytosed GeRPs in vivo and had little systemic dissemination, thus providing a means to deliver local therapeutics. Acute infarcts were then injected in vivo with phosphate-buffered saline (PBS; vehicle) or GeRPs loaded with siRNA to Map4k4, and excised hearts were examined at 3 and 7 days by quantitative polymerase chain reaction, flow cytometry, and histology. Compared with infarcted PBS-treated hearts, hearts with intrainfarct injections of siRNA-loaded GeRPs exhibited 69-89% reductions in transcripts for Map4k4 (mitogen-activated protein kinase kinase kinase kinase 4), interleukin (IL)-1ß, and tumor necrosis factor α at 3 days. Expression of other factors relevant to matrix remodeling-monocyte chemoattractant protein-1 (MCP-1), matrix metalloproteinases, hyaluronan synthases, matricellular proteins, and profibrotic factors transforming growth factor beta (TGF-ß), and connective tissue growth factor (CTGF)-were also decreased. Most effects peaked at 3 days, but, in some instances (Map4k4, IL-1ß, TGF-ß, CTGF, versican, and periostin), suppression persisted to 7 days. Thus, direct intramyocardial GeRP injection could serve as a novel and clinically translatable platform for in vivo RNA delivery to intracardiac macrophages for local and selective immunomodulation of the infarct microenvironment.

Near-Complete Genome Sequences of New Strains of Nylanderia Fulva Virus 1 from Solenopsis invicta.

Nylanderia fulva virus 1 (NfV-1) is a single-stranded positive-sense RNA virus that infects the tawny crazy ant. Three near-complete genomes of NfV-1SI (92% to 94% nucleotide identity to reference strain NfV-1) found infecting the red imported fire ant were determined. The genomes have 10,904 to 10,918 nucleotides and include most of the coding region for the polyprotein.

Transcriptome Sequencing of Immature Ants Reveals the Complete Genome Sequence of a New Isolate of Solenopsis invicta Virus 2 from the Mississippi Delta.

Solenopsis invicta virus 2 (SINV-2) is an RNA virus that infects red imported fire ants. I report the genome sequence of SINV-2MSD, an isolate infecting ants collected from Mississippi. The obtained genome is 11,303 nucleotides, including six open reading frames encoding four structural proteins, a helicase, and an RNA-dependent RNA polymerase.

Comparing web-based video interventions to enhance university student willingness to donate organs: A randomized controlled trial.

BACKGROUND: The efficacy of video interventions to increase organ donation willingness remains unclear. METHODS: Three-arm web-based randomized controlled trial involving 2261 students at 3 northeastern Ohio universities. Intervention students watched a live-action (n = 755) or animated (n = 753) donation video. Control students (n = 753) viewed wellness information from the Centers for Disease Control and Prevention (CDC). The primary outcome was proportion of students who visited their state electronic donor registry to consent. The secondary outcome was intervention quality. Logistic regression assessed the effects of interventions on visiting the state registry to provide donation consent while controlling for baseline variables. RESULTS: Students in the live-action video arm visited their state registry more frequently than students in the CDC arm (OR = 1.86, 95% CI = 1.20-2.88). There was no difference between students in the animated video and CDC arms (OR = 1.10, 95% CI = 0.69-1.76). The quality of the live-action video was rated lower than the animated video and the CDC text (75% ± 18, 84% ± 16, 80% ± 16, respectively; P < 0.001). CONCLUSION: Students who watched the live-action video were more willing to visit their electronic donor registry to register as organ donors, but rated it lower in satisfaction. Future work should identify the most potent components of organ donation interventions.

Differential Gene Expression in Red Imported Fire Ant (Solenopsis invicta) (Hymenoptera: Formicidae) Larval and Pupal Stages.

Solenopsis invicta Buren is an invasive ant species that has been introduced to multiple continents. One such area, the southern United States, has a history of multiple control projects using chemical pesticides over varying ranges, often resulting in non-target effects across trophic levels. With the advent of next generation sequencing and RNAi technology, novel investigations and new control methods are possible. A robust genome-guided transcriptome assembly was used to investigate gene expression differences between S. invicta larvae and pupae. These life stages differ in many physiological processes; of special importance is the vital role of S. invicta larvae as the colonies' "communal gut". Differentially expressed transcripts were identified related to many important physiological processes, including digestion, development, cell regulation and hormone signaling. This dataset provides essential developmental knowledge that reveals the dramatic changes in gene expression associated with social insect life stage roles, and can be leveraged using RNAi to develop effective control methods.

The current practice of mentoring across Accreditation Council of Graduate Medical Education - International accredited programs in Qatar from faculty and trainees perspectives.

PURPOSE: Mentoring plays a vital role in academic productivity, personal development, and career guidance for students, residents, fellows, and junior faculty. A culture of mentoring is spreading across residency and fellowship training programs in Hamad Medical Corporation, the main teaching tertiary care facility in Qatar. However, there is insufficient knowledge about the current practice of mentoring in these programs. METHODS: We conducted a cross-sectional study by surveying all faculty and trainees in all residency and fellowship training programs in Qatar. Each completed a web-based questionnaire that asked about the current experience, self-efficacy and measures of improvement of the current practice of mentoring across training programs. RESULTS: A total of 393/650 faculty members (61%), 187/250 fellows (74%), and 405/650 residents (62%) responded to the two surveys. Most (74% of faculty members) reported being current mentors, while 67% of residents and fellows reported that they currently have mentors. Faculty who received training in mentoring and those who had an established formal mentoring program in their departments were more likely to enroll in mentoring than others (86%, P<0.01; 71%, P<0.05%, respectively). Trainees suggested that the two main areas to improve the current mentoring initiative in their departments were to develop a structured mentoring program and to train the mentors. Content analysis revealed participants' confusion differentiating between the terms mentoring and supervision. CONCLUSION: Based on the current study, many existing mentoring relationships have an evident confusion between supervision and mentoring roles. Developing structured mentoring program and training both faculty and trainees in mentoring is recommended to improve the current practice of mentoring within the training programs.

Identifying acute cervicitis in an era of less-frequent routine gynecologic examinations.

Acute inflammation of the uterine cervix can lead to serious problems such as pelvic inflammatory disease (PID), endometritis, and complications of pregnancy and childbirth. As intervals for routine gynecologic screening examinations lengthen, cervical infections, especially if asymptomatic, may be missed. Annual wellness examinations and other patient visits outside routine gynecologic cancer screening visits should include brief evaluation with sexual risk assessment and a gynecologic examination if indicated. If cervicitis persists after standard treatment for sexually transmitted infections (STIs), consider Mycoplasma genitalium. Clinicians should be sensitive to the fact that the unexpected presence of infection may cause distress.

Allantoin Crystal Formation in Bagrada hilaris (Burmeister) (Heteroptera: Pentatomidae) Females.

Bagrada hilaris is a polyphagous herbivore reported as an invasive pest in the United States. During the course of dissecting Burmeister hilaris unique crystals were observed in both the midgut and oviducts. Crystals were identified using X-ray diffraction techniques. Both acicular (i.e., needle-like, slender, and/or tapered) and cubic (i.e., cube shaped) crystals were observed in six of 75 individuals examined (8.0%). The crystals were mainly observed in females (6.7%), followed by males (1.3%) with no crystals observed in the minimal number of nymphs examined (0%). Crystals of both types were detected in the midgut and lateral oviducts of the females and midgut in males. The acicular crystals often appeared as distinct bundles when present in the midgut and oviducts. Crystals varied in size with the acicular crystals ranging from 0.12 mm to 0.5 mm in length although the cubic crystals ranged in length from 0.25 mm to over 1.0 mm with widths of ∼0.25 mm. The cubic crystals were identified as allantoin although the acicular crystals were most likely dl-allantoin in combination with halite. While allantoin in a soluble form is often found in insect tissues and excreta; being present as a crystal, especially in such a large form, is curious and raises some interesting questions. More research is warranted to further understand mechanisms associated with such crystal formation in B. hilaris and can lead to a better understanding of the excretory process in this species and the role allantoin plays in the elimination of excess nitrogen.

Comparison of RNAi Sequences in Insect-Resistant Plants to Expressed Sequences of a Beneficial Lady Beetle: A Closer Look at Off-Target Considerations.

Sequences obtained from transcriptomes of the lady beetle Coleomegilla maculata were compared to those designed for incorporation into crops. Searches of the transcriptomes identified sequences as the most likely to be closely similar to the sequences described in RNAi plant incorporated products. Some proposed prime RNAi pest management targets were also used to identify predicted orthologs from C. maculata. The lady beetle sequences were aligned with sequences from corn rootworms and Colorado potato beetles and, as appropriate in the case of targets, regions of similarity were compared with the genetic model organism for beetles, Tribolium castaneum. Some high levels of nucleotide identity were identified, particularly with an actin-derived sequence from Colorado potato beetle. This actin-derived sequence shared identical sequences with the lady beetle and a parasitic wasp.
