RESUMEN
OBJECTIVE(S): To investigate the effectiveness of ciprofloxacin/dexamethasone in reducing granulation tissue post-tracheostomy in pediatric patients. METHODS: This cohort study examined pediatric patients with a tracheostomy at a single academic institution from 2016 to 2020. Exclusion criteria included: deceased within 1 year (n = 38), >16 years of age (n = 21), decannulated within 1 year (n = 15), lost to follow-up within 1 year (n = 6), and revision tracheostomy (n = 2). Logistic regression or Wilcoxon rank-sum (α = 0.05) were used to compare demographic and clinical characteristics between patients who did and did not receive ciprofloxacin/dexamethasone within 1 year of their tracheostomy. RESULTS: In this cohort, (n = 126, median age 5.2 months, 54.0 % male), 62.7 % received ciprofloxacin/dexamethasone within 1 year, with 27.8 % taking the nebulized form. Granulation tissue occurred in 81.0 % of cases, predominantly peristomal (69.8 %) and suprastomal (34.9 %). Notable complications included accidental decannulation (13.6 %), suprastomal collapse (11.2 %), and bleeding (7.2 %). Although granulation tissue was more common in ciprofloxacin/dexamethasone users (92.4 %) versus non-users (61.7 %) (OR: 7.55, 95 % CI: 2.73-20.9, p < 0.001), patients exhibited less frequent granulation tissue events after initiation (z = 3.88, p < 0.001). No significant differences in antibiotic resistance (p = 1.0) or endocrinology complications (p = 0.1) were found between those with and without ciprofloxacin/dexamethasone. CONCLUSIONS: We found a statistically significant reduction of granulation tissue incidence with ciprofloxacin/dexamethasone use and no significant differences in antibiotic resistance or endocrinology complications were noted. Future investigation is warranted to explore timing of ciprofloxacin/dexamethasone administration for granulation tissue and its role in managing and preventing tracheostomy complications.

BACKGROUND: Medical student involvement in procedures, including pelvic exams under anesthesia (EUAs), is a fundamental part of medical education. While guidelines exist regarding informed consent for medical student participation, there is ongoing debate and uncertainty regarding the requirement and modality of obtaining explicit consent for pelvic EUAs. This study aims to explore the perceptions and experiences of medical students who do not favor an explicit informed consent process for pelvic EUAs. METHODS: An anonymous online questionnaire was distributed to third- and fourth-year medical students at the University of Pittsburgh School of Medicine who had completed their obstetrics and gynecology core clerkship. The questionnaire included both quantitative and qualitative sections. Qualitative analysis was conducted using a mixed inductive and deductive coding approach, with key patterns, categories, and themes identified through content analysis. RESULTS: Among the 201 students included in the analysis, 50 students did not endorse an explicit informed consent process for pelvic EUAs. Themes that emerged from their open-ended responses included: (1) the belief that medical student involvement is implicitly included in patient agreements at teaching hospitals; (2) the perception that pelvic EUAs are an essential first step in gynecologic surgery; (3) the view that pelvic EUAs are comparable to other medical procedures; (4) concern that explicit consent would limit educational opportunities; and (5) the belief that pelvic EUAs are not harmful or traumatic to patients. DISCUSSION: The findings highlight the justifications provided by medical students who do not support explicit informed consent for pelvic EUAs. While some arguments align with previous ethical analyses, this study provides empirical and qualitative insights into students' perspectives. The belief that patients implicitly consent to medical student involvement at teaching hospitals warrants further examination, as patient awareness and understanding may vary. The differentiation between pelvic exams and other EUAs, as well as the perception of minimal harm, should be critically evaluated in the context of trauma-informed care and patient autonomy. Furthermore, the interconnectedness of educational and surgical aspects of pelvic EUAs should be clarified in patient-physician communication. CONCLUSION: Understanding the perspectives of medical students who do not favor explicit consent for pelvic EUAs is crucial for developing and implementing consent processes. The findings emphasize the need for enhanced patient-physician communication, standardized frameworks for learner involvement, and curricular adaptations to address patient perceptions and trauma-informed care. Future research should explore these themes in larger and more diverse cohorts to inform best practices in obtaining informed consent for medical student participation in pelvic EUAs.

OBJECTIVE: To obtain an overview of medical student attitudes on the need for explicit consent for pelvic exams under anesthesia performed for educational purposes DESIGN: From February to October 2020, 201 medical students at a single medical school in the United States participated in a cross-sectional survey after completion of the obstetrics and gynecology clerkship. Outcome measures included endorsement of need for explicit informed consent for educational pelvic exams under anesthesia, and knowledge of informed consent processes for such exams. SETTING: University of Pittsburgh School of Medicine PARTICIPANTS: Third- and fourth-year medical students RESULTS: Overall, 75% of medical students endorsed a need for explicit informed consent for educational pelvic exams under anesthesia, which extended to prostate, rectal, and breast exams under anesthesia. Additionally, 45% and 77% of these participants indicated that consent for educational pelvic exams under anesthesia should take the form of a separate signature line on the surgical consent form and/or a verbal form, respectively. Only 40% of students correctly identified institutional policy for obtaining informed consent for educational pelvic exams under anesthesia. Rotation with the oncologic surgical service (pâ¯=â¯0.02) and correct identification of institutional informed consent policies (pâ¯=â¯0.002) were associated with decreased perceptions of the importance of explicit informed consent for educational pelvic exams under anesthesia. CONCLUSIONS: Medical students at the institution studied largely support explicit informed consent for educational pelvic and other sensitive exams under anesthesia, but a knowledge gap on institutional informed consent policy exists. Medical students support increased transparency and bodily autonomy. Due to the agreement of patients and medical students and the ethical rationale for this position, it may be appropriate for physicians and institutions to consider new processes of obtaining explicit informed consent for pelvic exams under anesthesia by medical students.

Luchador and Nerujay are two newly isolated mycobacteriophages recovered from soil samples using Mycobacterium smegmatis. Their genomes are 53,387 bp and 53,455 bp long and have 96 and 97 predicted open reading frames, respectively. Nerujay is related to subcluster A1 phages, and Luchador represents a new subcluster, A14.
