RESUMO

OBJECTIVES: Patients with Bell's palsy, the sudden onset of facial paralysis, have variable recovery. Frailty has been recognized as an important factor in predicting recovery. This study investigated the relationship between frailty and facial nerve recovery in Bell's palsy patients. METHODS: A retrospective review was conducted on 95 Bell's palsy patients at a single institution's Department of Otolaryngology from 2014 to 2023. A clinically relevant facial nerve recovery was defined as a House-Brackmann (HB) score decrease>1 between the initial and most recent visit. Patients without follow-up visits or initial HB scores <3 were excluded. Frailty was measured by modified frailty index-5 (mFI-5) at the time of Bell's palsy diagnosis. Elderly patients were those over 65 years at presentation (n = 29). Frail patients had mFI-5 > 1 (n = 8). Chi-squared analyses, Fisher's exact tests, and logistic regression models were conducted in SPSS. RESULTS: The analytic sample included 95 patients (median age = 56.8 years, IQR = 24.1) presenting with an initial HB score > 2. 36 % of patients' HB scores decreased by ≥2 within the follow-up period. Frailty (unadjusted Odds Ratio (OR) = 6.3, 95 % CI = [1.2, 33.1], p = .023) was associated with facial nerve recovery while age was not (unadjusted OR = 1.07, 95 % CI = [0.44, 2.59], p = .889). The mFI-5 adjusted OR was 8.43 (95 % CI = [1.38, 51.4], p = .021) when adjusting for age, gender, treatment modality, access to care, and follow-up duration in a logistic regression. CONCLUSIONS: Frailty correlated with enhanced facial nerve recovery after Bell's palsy in this cohort; age was not significantly associated. Further investigation into factors associated with frailty, including increased surveillance and treatment frequency, is warranted.

RESUMO

BACKGROUND: Acute Descending Necrotizing Mediastinitis is a rare but serious illness that carries a high mortality rate. It is not commonly part of the Emergency Physician's differential diagnoses for the chief complaint of chest pain when there has been no recent instrumentation to the area. Because the disease is so uncommon, there is a relative paucity of reports of the illness. CASE REPORT: We report the case of a 58-year-old male with a past medical history of HIV and history of intravenous drug use (IVDU) who presented to the Emergency Department with anterior chest pain for several days in addition to 3 days of fever and chills. The patient's presentation raised concern for intrathoracic infection and the diagnosis of Descending Necrotizing Mediastinitis complicated by internal jugular thrombosis was confirmed by contrast enhanced computed tomography and sonography.

RESUMO

BACKGROUND: Although there is an abundance of literature on nonablative laser and energy-based therapies for the management of skin conditions, adverse events are inconsistently addressed and range widely across studies. Fitzpatrick skin phototypes (SPTs) IV to VI are believed to be at higher risk. OBJECTIVES: The aim of this study was to determine the types and rates of adverse events in nonablative laser and energy-based therapies among patients with SPTs IV to VI. METHODS: Articles addressing nonablative laser and energy-based therapies for skin rejuvenation and acne scarring in patients with SPTs IV to VI that provided data on adverse events were included. The pooled prevalence of each adverse event was calculated. To determine whether age, treatment indication, SPT, and device type influenced incidence, subgroup and meta-regression analyses were performed. Heterogeneity was evaluated with the I2 statistic. RESULTS: Forty-three studies were included in the meta-analysis. The sample size was 1654, and the median age of subjects was 39.4 years. The most common adverse events were postinflammatory hyperpigmentation (PIH) (rate, 8.1%) and prolonged erythema (rate, 0.6%). The rate of PIH was significantly higher for diode and erbium-doped lasers compared with intense pulsed light and radiofrequency. PIH correlated positively with SPT, laser density, and total energy delivered. CONCLUSIONS: Although the overall rate of adverse events in nonablative laser and energy-based therapies for SPTs IV to VI is low, the incidence of PIH is not insignificant. Certain lasers, such as diode, Q-switched Nd:YAG, and erbium-doped lasers, tend to have higher rates of PIH, whereas intense pulsed light and radiofrequency have minimal risk. Higher SPTs and higher energy deliverance correlate positively with the incidence of PIH.

RESUMO

Uncertainty is ubiquitous in science, but scientific knowledge is often represented to the public and in educational contexts as certain and immutable. This contrast can foster distrust when scientific knowledge develops in a way that people perceive as a reversals, as we have observed during the ongoing COVID-19 pandemic. Drawing on research in statistics, child development, and several studies in science education, we argue that a Bayesian approach can support science learners to make sense of uncertainty. We provide a brief primer on Bayes' theorem and then describe three ways to make Bayesian reasoning practical in K-12 science education contexts. There are a) using principles informed by Bayes' theorem that relate to the nature of knowing and knowledge, b) interacting with a web-based application (or widget-Confidence Updater) that makes the calculations needed to apply Bayes' theorem more practical, and c) adopting strategies for supporting even young learners to engage in Bayesian reasoning. We conclude with directions for future research and sum up how viewing science and scientific knowledge from a Bayesian perspective can build trust in science.

RESUMO

OBJECTIVES: Recognize the avoidable costs incurred due to overpacking of rhinoplasty instrument trays. Reduce rhinoplasty instrument trays by including only instruments used frequently. Establish methods to reduce trays prepared for other otolaryngologic procedures. METHODS: This is a prospective study. The study evaluates the specific use of instruments opened for rhinoplasty procedures at the New York Eye & Ear Infirmary of Mount Sinai. Instruments were counted in 10 rhinoplasty cases. Usage rate was calculated for each instrument. Additionally, all instruments used in at least 20% of cases were noted. This "20%" threshold was used to create new rhinoplasty tray inventories more reflective of actual instrument usage. Some instruments above the 20% threshold were included in multiples (i.e. two Adson Brown forceps vs. one curved iris scissor). RESULTS: 189 instruments were opened, and 32 instruments were used on average in each rhinoplasty. 55 instruments were used in at least 20% of cases. The 55 "high usage" instruments were used to create new, reduced rhinoplasty tray inventory lists. Based on our analysis, a new rhinoplasty tray inventory was created comprised of 68 instruments, a 64% reduction from 189. CONCLUSION: Instruments are sterilized and packed in gross excess for rhinoplasty procedures. Previously published figures estimate re-sterilization costs of $0.51 to $0.77 per instrument. Reduction in instruments opened from 189 to 68 is expected to lead to cost savings ranging from $62 to $93 per case, yielding a savings between $6200 and $9300 per 100 cases performed. LEVEL OF EVIDENCE: II-3.

RESUMO

BACKGROUND: Nonsurgical rejuvenation of the tear trough area via the use of injectable filler material has become a popular procedure in facial rejuvenation. This procedure offers immediate, albeit temporary, results with minimal recovery time. OBJECTIVES: The aim of this systematic review was to report on patient satisfaction and complication rates to further guide practitioners. METHODS: PubMed, Cochrane, and Scopus libraries were queried for articles containing relevant terms. Articles with more than 5 patients who reported on satisfaction and/or complications from the procedure were included for review. In addition to these variables, we noted other aspects of injection, including filler material, technique, and needle or cannula delivery. Studies that did not otherwise fulfill inclusion criteria for statistical analysis but reported on intravascular injection-related complications were cited. RESULTS: Initial query resulted in 1655 studies which were assessed for duplicates and inclusion/exclusion criteria. After screening, 28 articles were included for analysis. In total, 1956 patients were captured who had been injected with 1 of 4 materials: hyaluronic acid (1535), calcium hydroxyapatite (376), autologous fibroblast/keratin gel (35), and collagen-based filler (10). Short- and long-term satisfaction rates were 84.4% and 76.7%, respectively. Minor complications were common (44%). Secondarily, we found the use of cannula for filler injection of this region to be associated with a lower rate of ecchymosis (7% vs 17%, P < 0.05). CONCLUSIONS: Filler injection volumization of tear trough deformity is an effective technique for facial rejuvenation associated with high patient satisfaction. Multiple filler materials offer acceptable satisfaction and complication profiles.

RESUMO

Privacy and confidentiality are core considerations in education, while at the same time, using and sharing data-and, more broadly, open science-is increasingly valued by editors, funding agencies, and the public. This manuscript responds to an empirical investigation of students' perceptions of the use of their data in learning analytics systems by Ifentahler and Schumacher (Educational Technology Research and Development, 64: 923-938, 2016). We summarize their work in the context of the COVID-19 pandemic and the resulting shift to digital modes of teaching and learning by many teachers, using the tension between privacy and open science to frame our response. We offer informed recommendations for educational technology researchers in light of Ifentahler and Schumacher's findings as well as strategies for navigating the tension between these important values. We conclude with a call for educational technology scholars to meet the challenge of studying learning (and disruptions to learning) in light of COVID-19 while protecting the privacy of students in ways that go beyond what Institutional Review Boards consider to be within their purview.

RESUMO

Our objective was to describe the prescribing practices, clinical characteristics, and outcomes of patients treated with ceftolozane-tazobactam (C/T) for multidrug-resistant (MDR) Gram-negative infections. This was a multicenter, retrospective, cohort study at eight U.S. medical centers (2015 to 2019). Inclusion criteria were age ≥18 years and receipt of C/T (≥72 hours) for suspected or confirmed MDR Gram-negative infection. The primary efficacy outcome, evaluated among patients with MDR Pseudomonas aeruginosa infections, was composite clinical failure, namely, 30-day all-cause mortality, 30-day recurrence, and/or failure to resolve or improve infection signs or symptoms after C/T treatment. In total, 259 patients were included, and P. aeruginosa was isolated in 236 (91.1%). The MDR and extremely drug-resistant phenotypes were detected in 95.8% and 37.7% of P. aeruginosa isolates, respectively. The most common infection source was the respiratory tract (62.9%). High-dose C/T was used in 71.2% of patients with a respiratory tract infection (RTI) overall but in only 39.6% of patients with an RTI who required C/T renal dose adjustment. In the primary efficacy population (n = 226), clinical failure and 30-day mortality occurred in 85 (37.6%) and 39 (17.3%) patients, respectively. New C/T MDR P. aeruginosa resistance was detected in 3 of 31 patients (9.7%) with follow-up cultures. Hospital-acquired infection and Acute Physiological and Chronic Health Evaluation II (APACHE II) score were independently associated with clinical failure (adjusted odds ratio [aOR], 2.472 and 95% confidence interval [CI], 1.322 to 4.625; and aOR, 1.068 and 95% CI, 1.031 to 1.106, respectively). Twenty-five (9.7%) patients experienced ≥1 adverse effect (9 acute kidney injury, 13 Clostridioides difficile infection, 1 hepatotoxicity, 2 encephalopathy, and 2 gastrointestinal intolerance). C/T addresses an unmet medical need in patients with MDR Gram-negative infections.

RESUMO

PURPOSE: To evaluate whether patient demographics and surgical metrics varied among differently trained surgeons performing blepharoplasty. METHODS: The Statewide Planning and Research Cooperative System database was used to identify patients who underwent blepharoplasty in New York State. Surgeons were grouped based on residency training as listed in the New York State Physician Profile. Multivariate regression analysis was used to determine predictors of patient characteristics based on surgeon training. RESULTS: There were 361 surgeons who performed 39,932 cases of blepharoplasty in New York State from 2008 to 2016. When aggregated by surgeon training, there were significant differences among procedure times and total charges for blepharoplasty. On average, cases performed by ophthalmologists took 66.7 minutes and patients were charged $6,860; cases performed by otolaryngologists took 158.2 minutes and patients were charged $9,084; and cases performed by plastic surgeons took 131.8 minutes and patients were charged $11,028. Unlike plastic surgeons or otolaryngologists, ophthalmologists tended to have older patients and more male patients. Ophthalmologists were more likely to operate on patients with comorbidities as well as non-white patients (p < 0.0001). They were also significantly more likely to have patients with insurance coverage than self-pay (p < 0.0001). CONCLUSIONS: Demographic and surgical metrics of blepharoplasty cases performed by surgeons trained in otolaryngology and plastic surgery are similar. Ophthalmology-trained surgeons performed blepharoplasty on patients that were more likely to be older, male, non-white, and had insurance coverage. Ophthalmologist procedure time for blepharoplasty was also less than half of the procedure time of otolaryngologists and plastic surgeons.Blepharoplasty is a surgical procedure commonly performed by ophthalmologists, otolaryngologists, and plastic surgeons to address cosmetic concerns or visual impairment related to the eyelids.

RESUMO

PURPOSE OF THE REVIEW: This review paper is a comprehensive look at the cardiovascular disease (CVD) risk that is associated with the use of androgen deprivation therapy in prostate cancer. It summarizes when certain cancer therapies are indicated and should guide physicians in identifying patients at increased risk for CVD during prostate cancer therapy. RECENT FINDINGS: GnRH agonist use and maximal androgen blockade (MAB) are associated with increased CVD. This association is not observed in patients on GnRH antagonists. One example is the novel agent abiraterone, which is associated with hypertension whose mechanisms are likely driven by mineralocorticoid excess. Incidence of cardiovascular disease events is greatest when using MAB, especially in patients with pre-existing CVD. There is significant confounding that exists given patients with more aggressive cancers tend to be older and have more co-existing CVD. Given the lower CVD event rates with GnRH antagonists, future studies and strategies should focus on high-risk cancer patients with co-existing CVD receiving antagonists over agonists.

RESUMO

Social determinants of health have been widely studied throughout medicine; however, their role relating to functional rhinoplasty has not been previously evaluated. The records of 178 patients who underwent functional rhinoplasty in a single health network from 2013 to 2016 were reviewed. The Nasal Obstruction Symptom Evaluation (NOSE) score was used to assess patient-reported symptoms, and patients with both preoperative and postoperative NOSE scores were included in this study. Basic demographics and surgical techniques were also collected. Differences between NOSE scores and surgical approaches to functional rhinoplasty on the basis of insurance type were measured. One hundred and sixteen patients were included for analysis, the mean age was 34.7 years (standard deviation [SD] = 16.2) and 57 (49.1%) were female. Twenty-one (18.1%) patients had public insurance and, of these, 18 patients had Medicaid. Patients (mean, SD) with Medicaid insurance (56.39, 15.6) had a slightly greater improvement in NOSE scores compared with patients with non-Medicaid insurance (47.90, 25.6) (p = 0.067). There was no statistically significant difference in preoperative NOSE scores or postoperative improvement in NOSE scores between patients with different health insurance. Furthermore, there was no statistically significant difference in surgical approaches. The majority of patients receiving functional rhinoplasty had private insurance. Medicaid patients trended toward a greater NOSE score improvement after functional rhinoplasty, but also had a closer association with a history of nasal trauma and prior surgery. Future study is needed to better understand the association between socioeconomic status and disparities in care. Understanding how social determinants of health affect patients may reveal potential inherent biases, improve delivery of care, and translate to better patient outcomes.

RESUMO

Out-of-school time programs focused on science, technology, engineering and mathematics (STEM) have proliferated recently because they are seen as having potential to appeal to youth and enhance STEM interest. Although such programs are not mandatory, youth are not always involved in making the choice about their participation and it is unclear whether youth's involvement in the choice to attend impacts their program experiences. Using data collected from experience sampling, traditional surveys, and video recordings, we explore relationships among youth's choice to attend out-of-school time programs (measured through a pre-survey) and their experience of affect (i.e., youth experience sampling ratings of happiness and excitement) and engagement (i.e., youth experience sampling ratings of concentration and effort) during program activities. Data were collected from a racially and ethnically diverse sample of 10-16 year old youth (n = 203; 50% female) enrolled in nine different summer STEM programs targeting underserved youth. Multilevel analysis indicated that choice and affect are independently and positively associated with momentary engagement. Though choice to enroll was a significant predictor of momentary engagement, positive affective experiences during the program may compensate for any decrements to engagement associated with lack of choice. Together, these findings have implications for researchers, parents, and educators and administrators of out-of-school time programming.

RESUMO

Hairy cell leukemia (HCL) is a rare, indolent B-cell disorder in which single courses of cladribine induce high rates of complete responses. We report on 88 young HCL patients (≤40 years of age at diagnosis) treated with cladribine from the Scripps Clinic HCL Database, of whom 83 were evaluable for response. Seventy-three patients (88%) achieved an initial complete response and 10 (12%) a partial response, with a median response duration of 57 months. Forty-eight patients (58%) relapsed, with a median time to first relapse for all responders of 54 months. Eight patients developed 11 second primary malignancies with an excess frequency of 1.60 (95% confidence interval, 0.80-2.89). Thirteen (15%) patients died with a mortality ratio compared with age-matched normals of 1.85 (95% confidence interval, 1.07-3.18). Median overall survival for all patients following the first cladribine course was 231 months, and 251 months from diagnosis. Single courses of cladribine induce high rates of complete and durable responses in the majority of young HCL patients and are therefore recommended for HCL patients regardless of age.

RESUMO

Hydrolytic enzymes play crucial roles in cellular processes, and dysregulation of their activities is implicated in various physiological and pathological conditions. These enzymes cleave substrates such as peptide bonds, phosphodiester bonds, glycosidic bonds, and other esters. Detecting aberrant hydrolase activity is vital for understanding disease mechanisms and developing targeted therapeutic interventions. This study introduces a novel approach to measuring hydrolase activity using giant magnetoresistive (GMR) spin valve sensors. These sensors change resistance in response to magnetic fields, and here, they are functionalized with specific substrates for hydrolases conjugated to magnetic nanoparticles (MNPs). When a hydrolase cleaves its substrate, the tethered magnetic nanoparticle detaches, causing a measurable shift in the sensor's resistance. This design translates hydrolase activity into a real-time, activity-dependent signal. The assay is simple, rapid, and requires no washing steps, making it ideal for point-of-care settings. Unlike fluorescent methods, it avoids issues like autofluorescence and photobleaching, broadening its applicability to diverse biofluids. Furthermore, the sensor array contains 80 individually addressable sensors, allowing for the simultaneous measurement of multiple hydrolases in a single reaction. The versatility of this method is demonstrated with substrates for nucleases, Bcu I and DNase I, and the peptidase, human neutrophil elastase. To demonstrate a clinical application, we show that neutrophil elastase in sputum from cystic fibrosis patients hydrolyze the peptide-GMR substrate, and the cleavage rate strongly correlates with a traditional fluorogenic substrate. This innovative assay addresses challenges associated with traditional enzyme measurement techniques, providing a promising tool for real-time quantification of hydrolase activities in diverse biological contexts.

RESUMO

OBJECTIVES: Augmented reality (AR) and virtual reality (VR) are emerging technologies with wide potential applications in health care. We performed a scoping review of the current literature on the application of augmented and VR in the field of facial plastic and reconstructive surgery (FPRS). DATA SOURCES: PubMed and Web of Science. REVIEW METHODS: According to PRISMA guidelines, PubMed and Web of Science were used to perform a scoping review of literature regarding the utilization of AR and/or VR relevant to FPRS. RESULTS: Fifty-eight articles spanning 1997-2023 met the criteria for review. Five overarching categories of AR and/or VR applications were identified across the articles: preoperative, intraoperative, training/education, feasibility, and technical. The following clinical areas were identified: burn, craniomaxillofacial surgery (CMF), face transplant, face lift, facial analysis, facial palsy, free flaps, head and neck surgery, injectables, locoregional flaps, mandible reconstruction, mandibuloplasty, microtia, skin cancer, oculoplastic surgery, rhinology, rhinoplasty, and trauma. CONCLUSION: AR and VR have broad applications in FPRS. AR for surgical navigation may have the most emerging potential in CMF surgery and free flap harvest. VR is useful as distraction analgesia for patients and as an immersive training tool for surgeons. More data on these technologies' direct impact on objective clinical outcomes are still needed.

RESUMO

BACKGROUND: The COVID-19 pandemic forced otolaryngologists to seek new methods of providing patient care in a remote setting. The effect of this paradigm shift on patient satisfaction, however, remains unelucidated. This study compares patient satisfaction with telehealth visits during the COVID-19 pandemic to that with in-office visits during the same period in 2019. METHODS: Press Ganey survey responses of patients seen by otolaryngologists within a large, academic, multicenter hospital system were gathered. Responses were included in analyses if they corresponded with a visit that occurred either in clinic March to December 2019 or via telehealth March to December 2020. Chi-Square Test of Independence and Fisher's Exact Test were employed to detect differences between years. Binary logistic regressions were performed to detect the factors most predictive of positive telehealth experiences. RESULTS: Patient overall satisfaction with in-office and telehealth visits did not differ significantly (76.4% in 2019 vs 78.0% in 2020 rated visit overall as "very good," P = .09). Patients seen by a Head and Neck (odds ratio 4.13, 95% confidence interval 1.52-11.26, P = .005), Laryngology (OR 5.96, 95% CI 1.51-23.50, P = .01), or Rhinology (OR 4.02, 95% CI 1.55-10.43, P = .004) provider were significantly more likely to report a positive telehealth experience. CONCLUSIONS: Patients seen via telehealth during COVID-19 reported levels of satisfaction similar to those seen in-office the year prior. These telehealth satisfaction levels, however, are contextualized within the expected confines of a pandemic. Further research is required to determine whether satisfaction remains consistent as telemedicine becomes a ubiquitous component of medical practice.

RESUMO

Complications posed by preterm birth (delivery before 37 weeks of pregnancy) are a leading cause of newborn morbidity and mortality. The previous discovery and validation of an algorithm that includes maternal serum protein biomarkers, sex hormone-binding globulin (SHBG), and insulin-like growth factor-binding protein 4 (IBP4), with clinical factors to predict preterm birth represents an opportunity for the development of a widely accessible point-of-care assay to guide clinical management. Toward this end, we developed SHBG and IBP4 quantification assays for maternal serum using giant magnetoresistive (GMR) sensors and a self-normalizing dual-binding magnetic immunoassay. The assays have a picomolar limit of detections (LOD) with a relatively broad dynamic range that covers the physiological level of the analytes as they change throughout gestation. Measurement of serum from pregnant donors using the GMR assays was highly concordant with those obtained using a clinical mass spectrometry (MS)-based assay for the same protein markers. The MS assay requires capitally intense equipment and highly trained operators with a few days turnaround time, whereas the GMR assays can be performed in minutes on small, inexpensive instruments with minimal personnel training and microfluidic automation. The potential for high sensitivity, accuracy, and speed of the GMR assays, along with low equipment and personnel requirements, make them good candidates for developing point-of-care tests. Rapid turnaround risk assessment for preterm birth would enable patient testing and counseling at the same clinic visit, thereby increasing the timeliness of recommended interventions.

RESUMO

This paper presents an analog front-end (AFE) for fast-scan cyclic voltammetry (FSCV) with analog background subtraction using a pseudo-differential sensing scheme to cancel the large non-faradaic current before seeing the front-end. As a result, the AFE can be compact and low-power compared to conventional FSCV AFEs with dedicated digital back-ends to digitize and subtract the background from subsequent recordings. The reported AFE, fabricated in a 0.18- µ m CMOS process, consists of a class-AB common-mode rejection circuit, a low-input-impedance current conveyor, and a 1st-order current-mode delta-sigma (ΔΣ) modulator with an infinite impulse response quantizer. This AFE achieves an effective dynamic range of 83 dB with a state-of-the-art 39.2 pArms input-referred noise when loaded with a 1 nF input capacitance (26.5 pArms open-circuit) across a 5 kHz bandwidth while consuming an average power of 3.7 µW. This design was tested with carbon-fiber microelectrodes scanned at 300 V/s using flow-injection of dopamine, a key neurotransmitter.

RESUMO

The fields of entomology, geospatial science, and science communication are understaffed in many areas, resulting in poor community awareness and heightened risks of vector-borne diseases. This is especially true in East Tennessee, where La Crosse encephalitis (LACE) causes pediatric illness each year. In response to these problems, we created a community engagement program that includes a yearlong academy for secondary STEM educators in the 6-12 grade classroom. The objectives of this program were to support inquiry-driven classroom learning to foster student interest in STEM fields, produce community-driven mosquito surveillance, and enhance community awareness of LACE. We trained educators in medical entomology, geospatial science, and science communication, and they incorporated those skills into lesson plans for a mosquito oviposition experiment that tested hypotheses developed in the classroom. Here, we share results from the first two years of the MEGA:BITESS academy, tailored for our community by having students ask questions directly related to Aedes mosquito oviposition biology and La Crosse encephalitis. In year one, we recruited 17 educators to participate in the project, and 15 of those educators returned in year two. All participating educators completed the academy, conducted the oviposition experiment, and informed over 400 students about a variety of careers and disciplines for their students. Here, we present a community-based program that helps to address the problems associated with long-term mosquito surveillance, health and science education and communication, career opportunities, and the community needs of Appalachia, as well as the initial data on the effectiveness of two years of an educator-targeted professional-development program.
