Junior doctors' workplace well-being and the determinants based on ability-motivation-opportunity (AMO) theory: Educational and managerial implications from a three-year longitudinal observation after graduation.

PURPOSE: Junior doctors function as trainees from an educational perspective and as employees from a human resource management perspective. Employing the ability-motivation-opportunity (AMO) theory as a conceptual framework, this study longitudinally investigated the factors affecting the workplace well-being and career progression of junior doctors over a 3-year period following their graduation from medical schools. MATERIALS AND METHODS: This 3-year prospective cohort study enrolled junior doctors who graduated from 2 medical schools in June 2019 in Taiwan. This study collected data by implementing web-based, self-administered structured questionnaires at 3-month intervals between September 2019 and July 2022. The collected data encompassed ability indicators (i.e. academic performance and perceived preparedness for clinical practice), motivation indicators (i.e. educational and clinical supervision), opportunity indicators (i.e. clinical unit cultures), and workplace well-being indicators (i.e. burnout, compassion satisfaction, and job performance). A total of 107 junior doctors participated, providing 926 total responses. The data were analysed using univariate analyses and structural equation modelling with path analysis. RESULTS: Over the 3-year period following graduation, the junior doctors' confidence in their preparedness for clinical practice and the educational and clinical supervision had varying degrees of influence on the junior doctors' workplace well-being. The influence of clinical unit cultures, which can provide opportunities for junior doctors, became evident starting from the second year postgraduation; notably, unit cultures that emphasised flexibility and discretion played positive and critical roles in enhancing the junior doctors' workplace well-being lasted to the third year. CONCLUSIONS: Our findings provide insights into the distinct critical factors that affect the socialisation of junior doctors within workplace environments over 3 consecutive years. These findings can provide guidance for medical educators and healthcare managers, helping them understand and support the progressive integration of junior doctors into their work environments.

Association between angiotensin-converting enzyme inhibitors or angiotensin receptor blockers and community-acquired pneumonia: A nationwide population propensity-score matching study.

BACKGROUND: Few large-scale cohort studies have investigated the association between community-acquired pneumonia and the use of angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin II receptor blockers (ARBs). We aimed to study whether using ACEIs or ARBs had protective effects for community-acquired pneumonia. METHODS: This database cohort study was conducted retrospectively in Taiwan. The hypertensive patients were the target population of this study. Patients with ARB use were defined as our first study cohort. The second study cohort comprised patients who used ACEI. Propensity-score matching at 1:1 was used between ARB users and non-ARB users. We recruited 67 944 participants for the ARB study and 58 062 participants for the ACEI study. The same matching was also performed between ACEI users and non-ACEI users. Cox proportional hazard regression was used to analyse the risk of the outcome of viral pneumonia. RESULTS: The hazard ratio of community-acquired pneumonia for ARB users relative to non-ARB users was 0.33. The hazard ratio of community-acquired pneumonia was 0.71 times in ACEI users compared with ACEI nonusers. In stratification analysis, both ARB and ACEI both exhibited a protective effect for community-acquired pneumonia in each age and sex group. In the analysis of the effects of therapy duration, patients using ARB for fewer than 100 days exhibited a greater reduction in the risk of community-acquired pneumonia (adjusted HR = 0.58) compared with the non-ARB cohort. For the ACEI study, patients who used ACEI for 121-450 days were more likely to exhibit reduced risks of community-acquired pneumonia (adjusted HR = 0.5). CONCLUSION: Both ACEI and ARB uses were associated with decreased risk of community-acquired pneumonia infection.

Medical students' preclinical service-learning experience and its effects on empathy in clinical training.

BACKGROUND: Service learning (SL) is an educational methodology presumed to help medical students be more empathetic and compassionate. We longitudinally investigated the level of empathy in medical students and how preclinical SL experience was related to their level of empathy in their clinical clerkships. METHODS: Our cohort comprised fifth-year medical students engaged in clerkships as part of a 7-year medical programme at one medical school in Taiwan. Surveys were conducted at the beginning of the clerkship in September 2015 (T1) to collect data on the medical students' preclinical SL experience in curriculum-based service teams (CBSTs) and extracurricular service teams (ECSTs) and their SL self-efficacy, demographic characteristics, and empathy level. Subsequently, three follow-up surveys were conducted once every 3 months to determine the empathy level of the students during their clinical clerkships (T2-T4). Seventy students who returned the written informed consent and completed the baseline (T1) and two or more follow-up surveys (T2-T4) were included in our analysis with the response rate of 34%. In total, 247 responses across the 1-year clerkship were analysed. Descriptive statistics, paired t tests, and generalised estimating equations were employed. RESULTS: Our study revealed that changes in empathy level in the dimensions of perspective taking, compassionate care, and standing in patients' shoes in their clinical clerkships. Relative to that at T1, their empathy decreased in perspective taking and compassionate care at T2-T4 but increased in standing in patients' shoes at T3. Additionally, our study verified the positive effect of medical students' preclinical SL experience in CBSTs and ECSTs on empathy in terms of compassionate care and perspective taking, respectively, but not on that of standing in patients' shoes. CONCLUSIONS: Separate investigations into subconstructs of empathy, such as perspective taking, compassionate care, and standing in patients' shoes, in medical students may be necessary for exploring the various driving forces or barriers to developing empathy in medical students. Moreover, SL experience through both CBSTs and ECSTs at medical academies may have positive effects on medical students' empathy in their clinical clerkships and should be promoted at medical schools.

Medical students' resilience: a protective role on stress and quality of life in clerkship.

BACKGROUND: Resilience refers to the ability to be flexible and adaptive in response to challenges. Medical students in clerkship who are transitioning from medical studies to clinical practice face a variety of workplace demands that can lead to negative learning experiences and poor quality of life. This study explored whether medical students' resilience plays a protective role against the stresses incurred during workplace training and on their professional quality of life during clerkships. METHODS: This was a 1-year prospective web-based questionnaire study comprising one cohort of medical students in their fifth year who were working as clerks as part of their 6-year medical education programme at one medical school in Taiwan between September 2017 and July 2018. Web-based, validated, structured, self-administered questionnaires were used to measure the students' resilience at the beginning of the clerkship and their perceived training stress (i.e. physical and psychological demands) and professional quality of life (i.e. burnout and compassion satisfaction) at each specialty rotation. Ninety-three medical students who responded to our specialty rotation surveys at least three times in the clerkship were included and hierarchical regressions were performed. RESULTS: This study verified the negative effects of medical students' perceived training stress on burnout and compassion satisfaction. However, although the buffering (protective) effects of resilience were observed for physical demands (one key risk factor related to medical students' professional quality of life), this was not the case for psychological demands (another key risk factor). In addition, through the changes in R square (∆R2) values of the hierarchical regression building, our study found that medical students' perceived training stresses played a critical role on explaining their burnout but their resilience on their compassion satisfaction. CONCLUSIONS: Medical students' resilience demonstrated a buffering effect on the negative relationship between physical demands and professional quality of life during clerkships. Moreover, different mechanisms (predictive paths) leading to medical students' professional quality of life such as burnout and compassion satisfaction warrant additional studies.

Lactoferrin interacts with SPLUNC1 to attenuate lipopolysaccharide-induced inflammation of human nasal epithelial cells via down-regulated MEK1/2-MAPK signaling.

The short palate, lung, and nasal epithelium clone 1 (SPLUNC1) protein is an important innate material in the upper airway, and lactoferrin (LF) aids the innate functions in humans. In this study, a nasal epithelial model was used to investigate how LF modulates SPLUNC1 to reduce the inflammatory process mediated by lipopolysaccharide (LPS). The inflammation of human RPMI-2650 cells was induced with LPS to evaluate SPLUNC1 expression after treating the cells with bovine LF (bLF). The interaction pathway between LF and SPLUNC1 in LPS-induced inflammation was further investigated. Our study reveals that the addition of bLF results in the recovery of SPLUNC1 expression in nasal epithelial cells under LPS-induced inflammation. MAPK is involved in the main pathway for the SPLUNC1 and bLF interaction. Decreased SPLUNC1 function could be recovered by addition of bLF. The MEK1/2-MAPK signaling pathway is crucial for the SPLUNC1 and bLF interaction. Therefore, LF could support SPLUNC1 in the innate immunity recovery process.

Subcortical neural representation to Mandarin pitch contours in American and Chinese newborns.

Voice pitch carries important information for speech understanding. This study examines the neural representation of voice pitch at the subcortical level, as reflected by the scalp-recorded frequency-following responses from ten American and ten Chinese newborns. By utilizing a set of four distinctive Mandarin pitch contours that mimic the English vowel /yi/, the results indicate that the rising and dipping pitch contours produce significantly better tracking accuracy and larger response amplitudes than the falling pitch contour. This finding suggests a hierarchy of potential stimuli when testing neonates who are born in a tonal or non-tonal linguistic environment.

Pitch perception and frequency-following responses elicited by lexical-tone chimeras.

OBJECTIVE: Previous research has shown the usefulness of utilizing auditory chimeras in assessing a listener's perception of the envelope and fine structure for an acoustic stimulus. However, research comparing and contrasting behavioral and electrophysiological responses to this stimulus type is scarce. DESIGN: Two sets of chimeric stimuli were constructed by interchanging the envelopes and fine-structures of the rising/yi(2)/and falling/yi(4)/Mandarin pitch contours that were filtered through 1, 2, 4, 8, 16, 32, and 64 frequency banks. Behavioral pitch-perception tasks were administered through a two-alternative, forced-choice paradigm. Electrophysiological responses were measured through scalp-recorded frequency-following responses (FFRs) to the lexical-tone chimeras. STUDY SAMPLE: Twenty American and twenty Chinese adults were recruited. RESULTS: A two-way analysis of variance showed significance (p < 0.05) within and across the filter bank and language background factors for the behavioral measurements, while the frequency-following response demonstrated a significance only across the filter banks. CONCLUSIONS: Perceptual importance of envelope cues increases starting from 16 filter banks, while the FFR accuracy and magnitude decreases with increasing number of filter banks. These results can be useful in assessing experience-dependent neuroplasticity and in designing speech processing strategies for cochlear-implant users who speak tonal or non-tonal languages around the globe.

Influence of clerks' personality on their burnout in the clinical workplace: a longitudinal observation.

BACKGROUND: The clinical training of medical students in clerkship is crucial to their future practice in healthcare services. This study investigates burnout during a 2-year clerkship training period as well as the role of personality traits on burnout during training. METHODS: Ninety-four clerks at a tertiary medical centre who provided at least 10 responses to a routine survey on clinical rotation were included in this study, which spanned September 2013 to April 2015. Web-based, validated, structured, self-administered questionnaires were used to evaluate the clerks' personalities at the beginning of the first clerkship year, and regular surveys were conducted to evaluate their burnout at each clinical specialty rotation throughout the 2-year clerkship period. Overall, 2230 responses were analysed, and linear mixed-effects models were used to examine the repeated measures of the clerks. RESULTS: Our findings revealed that medical student burnout scores were lower in the second year than they were in the first year of clerkships. Using the Big Five personality factors, all of the propensities, namely extroversion, agreeableness, consciousness, emotional stability, and openness were related to different extents of burnout reduction in the first clerkship year (P < .05). However, only emotional stability and openness were related to clerks' reduced burnout in the second clerkship year. Furthermore, being female, older, and with accompanied living were more closely related to lower burnout compared with being male, younger, and living alone throughout the clerkship period. CONCLUSIONS: The students in the first-year clerkship, particularly those with higher burnout levels, had tendencies in the Big Five personality characteristics, exhibiting higher levels of introversion, antagonism, lack of direction, neuroticism, and not open to new experiences. The students in the second-year clerkship who do not exhibit a high propensity for emotional stability and openness should be of particular concern. The findings can serve as a reference for clinical teachers and mentors to effectively prevent and reduce the burnout of medical students during clerkship training at clinical workplaces.

Training demands on clerk burnout: determining whether achievement goal motivation orientations matter.

BACKGROUND: In the education field, learning experiences are considered learners' properties and are viewed as a key determinant in explaining learners' learning processes, especially for training novices such as clerks with varying levels of commitment to the medical profession. This study explored whether clerks' achievement goal motivation orientations might buffer the negative well-being to a certain extent, considering their training demands during clinical training. METHODS: Ninety-four clerks at a tertiary medical center were longitudinally traced during their 2-year clerkship spanning from September 2013 to April 2015. Web-based, validated, structured, self-administered questionnaires were used to evaluate the clerks' properties of achievement goal motivation orientation and personal background at the beginning of the clerkship. Regular surveys were conducted to evaluate their perceptions of training demands and burnout at each specialty rotation. Overall, 2230 responses were analyzed, and linear mixed-effects models were used to examine the repeated measures of the clerks. RESULTS: The results revealed that higher perceived psychological and physical demands of training were related to higher perceived burnout during the 2-year clerkship. Although both the clerks' task and ego orientations were related to reduced burnout (direct effects), only task orientation was indicated to exert a buffering effect on their perception of physical demands on burnout in the 1st year of the clerkship. CONCLUSIONS: Considering the negative effects of training demands (psychological and physical), we observed a limited effect of the task achievement motivation orientation of medical students; therefore, additional studies might focus on strategies to facilitate medical students in clerkships in addressing both the psychological and physical demands inherent in training workplaces to improve their learning experience and well-being.

Decreased PLUNC expression in nasal polyps is associated with multibacterial colonization in chronic rhinosinusitis patients.

PLUNC (palate, lung, and nasal epithelium clone) is an epithelium-secreted protein that plays a crucial role in the host's defense against bacterial infection. The function of PLUNC in the sinus remains poorly understood. To examine whether the expression levels of PLUNC could serve as a predictive outcome biomarker for patients with CRSwNP and bacterial colonization, we investigated the association of PLUNC expression levels with bacterial colonization in the sinuses. A total of 174 patients who underwent sinus surgery for chronic rhinosinusitis with nasal polyps (CRSwNP) were enrolled in this study. The tissue samples obtained from patients were examined using preoperative sinus computed tomography (CT) scans, postoperative bacterial cultures, and nasal polyp examinations. PLUNC mRNA and protein expression were quantified using RT-PCR and immunohistochemistry. We identified that decreased PLUNC expression is associated with multibacterial colonization (P = 0.0001), specifically those mediated by Staphyloccocus aureus (P = 0.037) and Pseudomonas aeruginosa (P = 0.002). The patients who required repeated sinus surgeries for recurrent or persistent sinusitis also presented much lower PLUNC expression than those who did not require repeated sinus surgery (P = 0.001). However, gender, age, and CT scores were not associated with PLUNC expression. These results suggest that reduced PLUNC expression is associated with bacterial colonization as well as treatment outcome in CRSwNP patients. Investigation of the association between PLUNC expressions and chronic rhinosinusitis may lead to the development of a novel biomarker for treatment outcome in CRSwNP patients.

A web-based audiometry database system.

To establish a real-time, web-based, customized audiometry database system, we worked in cooperation with the departments of medical records, information technology, and otorhinolaryngology at our hospital. This system includes an audiometry data entry system, retrieval and display system, patient information incorporation system, audiometry data transmission program, and audiometry data integration. Compared with commercial audiometry systems and traditional hand-drawn audiometry data, this web-based system saves time and money and is convenient for statistics research.

Recording frequency-following responses to voice pitch in guinea pigs: preliminary results.

Although scalp-recorded frequency-following response (FFR) to voice pitch has shown great potential to examine pitch processing mechanisms in human participants and animals, few reports have addressed the test-retest reliability of such a response in an animal model. The purpose of this study was to investigate the feasibility and reliability of recording such a response in an animal model and to evaluate the extent to which the response could be separated from background noise. A Chinese monosyllable with a rising pitch was used to elicit the FFR to voice pitch in four guinea pigs. Four objective measures (Root-Mean-Square, Amplitude, Tracking Accuracy, Frequency Error, and Slope Error) were computed from recorded brain waves and were used to examine the phase-locking magnitude and test-retest reliability of the response. Results demonstrated that the animal model produced FFR trends that were repeatable, reliable, and significantly different from responses to the background noise.

Effects of grit on medical students' wellbeing during clerkships: a longitudinal observational cohort study.

Introduction: In medical education, the clerkship phase is a demanding period during which medical students learn to navigate the responsibilities of medical school and clinical medicine. Grit, a personal quality regarded as a non-cognitive trait, refers to perseverance and passion; specifically, it represents the ability to endure hardship and work industriously toward a goal. Most studies analysed grit as a single concept and few studies have investigated the effect of grit on the well-being of medical students through the whole-specialty training (i.e. surgical and non-surgical specialty rotations) required in clinical clerkships. Therefore, this study investigated whether associations exist between medical students' grit, measured by the two subconstructs of perseverance and passion, and their well-being during clerkships in surgical and non-surgical specialty units. Methods: This one-year prospective web-based questionnaire study enrolled fifth-year medical students at a tertiary medical centre in central Taiwan between September 2017 and July 2018 in their first-year clerkship. The students' sex, age, and grit were measured at the start of their clerkship. Routine surveys were conducted over one year to assess burnout and compassion satisfaction for students' well-being, and the training specialty characteristics of the surgical and non-surgical specialty departments were recorded. This study included 92 medical students and 1,055 survey responses from individual specialty rotations. Descriptive, univariate and multivariate analyses were performed. Results: Our results revealed that medical students' perseverance, as part of grit, was related to lower burnout and higher compassion satisfaction during clerkships, but not the subconstruct of passion. Moreover, the positive trait of perseverance measured in our study had greater explanatory power for compassion satisfaction than for burnout. Furthermore, the results revealed that older medical students suffered from less burnout than their younger counterparts, and that male medical students expressed higher compassion satisfaction than their female counterparts. Discussion: Perseverance, as a subconstruct of grit, is a positive personal quality for medical students' clerkships, and methods driving the cultivation of perseverance in medical education should be considered. In addition, even though positive traits such as perseverance equipped medical students for compassion satisfaction, additional factors attributed to medical students' burnout must be identified.

Adult-onset congenital cholesteatoma in the hypotympanum initially presenting as Bell's palsy: A case report.

INTRODUCTION: Cholesteatoma is a rare disease characterized by the accumulation of keratinized squamous epithelial cells in the middle ear or mastoid cavity. Vertigo and facial palsy, which are rare complications, may indicate erosion into the semicircular canals or the fallopian canal. PATIENT CONCERNS: A 40-year-old woman presented to our clinic with progressive right-sided hearing loss over 5 years (primary concern). Approximately 10 years ago, the patient had developed acute right-sided facial weakness with no additional symptoms. A neurologist at another hospital had diagnosed her condition as Bell's palsy and treated it accordingly. DIAGNOSIS: Adult-onset congenital cholesteatoma in the hypotympanum. INTERVENTION: Combined endoscopic and microscopic removal of the cholesteatoma. OUTCOMES: Physical examination revealed slight improvement in right-sided peripheral facial palsy. LESSON: Routine eardrum examination is recommended for patients presenting with isolated peripheral facial palsy. If necessary, a patient should be referred to an otologist for further evaluation and treatment.

Bacteriology of Different Phenotypes of Chronic Rhinosinusitis.

OBJECTIVES: Chronic rhinosinusitis (CRS) reduces the health-related quality of life and subsequently causes a tremendous socio-economic impact. Although many studies have been conducted, few have identified a relationship between bacteriological characteristics and different phenotypes or endotypes. Therefore, this study aimed to elucidate the recent trends in bacterial cultures from different types of CRS in the Asian population. METHODS: This retrospective case-control study recruited patients diagnosed with CRS who underwent functional endoscopic sinus surgery (FESS) at a tertiary hospital in Taiwan. The patients were classified into those with chronic rhinosinusitis with nasal polyps (CRSwNP)/chronic rhinosinusitis without nasal polyps (CRSsNP), eosinophilic chronic rhinosinusitis (eCRS)/non-eosinophilic chronic rhinosinusitis (NECRS), and central compartment atopic disease (CCAD)/lateral-dominant nasal polyp (LDNP) groups. The demographic data and bacteriological characteristics of the groups were analyzed. RESULTS: We included 503 patients, identifying no significant difference between CRSwNP and CRSsNP for several common bacteria in CRS. The number of Staphylococcus epidermidis isolates in culture was significantly higher in the NECRS group (50.46% vs. 32.56%, p = 0.0003) than that in the eCRS group. The number of methicillin-resistant Staphylococcus aureus (MRSA; 8.51% vs. 2.35%, p = 0.0221) positive isolates was significantly higher in the CCAD group than that in the LDNP group. CONCLUSIONS: This was the first study in Asia to analyze the relationship between bacteriological characteristics and CCAD. MRSA is significantly higher in the CCAD group than that in the LDNP group. Recognizing the unique microbiology of CRSwNP, eCRS, and CCAD is crucial when selecting antimicrobial therapy to lessen the socio-economic impact.

Increased risk of hearing loss associated with MT-RNR1 gene mutations: a real-world investigation among Han Taiwanese Population.

BACKGROUND: Previous studies have implicated inherited mutations in mitochondrial DNA (mtDNA) in sensorineural hearing loss (SNHL). However, the definitive association between mitochondrial 12S rRNA (MT-RNR1) variants and hearing loss in the population has not been well established, particularly in Asia. The objective of this retrospective cohort study was to assess the association between MT-RNR1 variants and the risk of SNHL in patients in Taiwan. METHODS: The cohort included 306,068 participants from Taiwan between January 2003 and December 2020. Participants were classified based on genetic variants, particularly mitochondrial mutations (rs267606618, rs267606619, rs267606617). MT-RNR1 variant cases were matched 1:10 with non-mutant patients by age, gender, and visit year, excluding those with pre-existing hearing loss. The primary endpoint was SNHL, identified using specific ICD-TM codes with a 90% positive predictive value. Medication exposure history was determined via self-report or electronic medical records in the hospital. Cox proportional hazard regression models were used to assess the association between MT-RNR1 variants and hearing loss, adjusting for various covariates. Kaplan-Meier survival curves and log-rank tests compared hearing loss incidence between groups. RESULTS: The mean age of the mtDNA variants group is 32.4 years, with a standard deviation of 19.2 years. The incidence density of hearing loss for the mutation group was 36.42 per 10,000 person-years (95% Confidence Interval [CI], 27.21-47.73), which was higher than the 23.77per 10,000 person-years (95% CI, 21.32-26.42) in the wild-type group (p = 0.0036). Additionally, diabetes mellitus was associated with an increased risk of developing SNHL in individuals with MT-RNR1 variants (adjusted hazard ratio = 1.76 [95% CI, 1.00-3.09], p < 0.05). CONCLUSION: This study highlights the increased risk of hearing loss in patients carrying MT-RNR1 variants, particularly those with diabetes mellitus. Future research that integrates genetic and clinical data is crucial for developing more precise interventions to monitor and treat hearing loss in this vulnerable population.

Clinical Outcomes of Severe Rhinosinusitis Complicated with Cavernous Sinus Syndrome.

Background: Various diseases involving the cavernous sinus can cause a condition called cavernous sinus syndrome (CSS), which is characterized by ophthalmoplegia or sensory deficits over the face resulting from the compression effect of internal structure. While tumor compression is the most reported cause of CSS, statistical data on CSS caused by infections are limited. Its risk factors, treatment methods, and clinical outcomes are not well-documented. Methods: In this retrospective study, we reviewed the data of patients admitted to a tertiary medical center from 2015 to 2022 with a diagnosis of acute and chronic sinusitis and at least one diagnostic code for CSS symptoms. We manually reviewed whether patients were involved in two or more of the following cranial nerves (CN): CN III, CN IV, CN V, or CN VI, or at least one of these nerves with a neuroimaging-confirmed lesion in the cavernous sinus. Results: Nine patients were diagnosed with rhinosinusitis-related CSS. The most common comorbidity was type 2 diabetes, and the most common clinical manifestations were diplopia and blurred vision. The sphenoid sinus was the most affected sinus. One patient expired due to a severe brain abscess infection without surgery. The remaining patients underwent functional endoscopic sinus surgery, and 50% of the pathology reports indicated fungal infections. Staphylococcus spp. was the most cultured bacteria, and Amoxycillin/Clavulanate was the most used antibiotic. Only four patients had total recovery during the follow-up one year later. Conclusions: CSS is a rare but serious complication of rhinosinusitis. Patients with diabetes and the elderly may be at a higher risk for this complication. Even after treatment, some patients may still have neurological symptoms.

Increased risks of retinal vascular occlusion in patients with migraine and the protective effects of migraine treatment: a population-based retrospective cohort study.

Associations between migraine and retinal vascular occlusion have been reported, but there is no large-scale and comprehensive study. Therefore, we aimed to determine risks of retinal vascular occlusion in patients with migraine. Using the Taiwan National Health Insurance Research Database from 2009 to 2020, we enrolled 628,760 patients with migraine and 628,760 matched individuals without migraine. Study outcomes were diagnoses of retinal vascular occlusion, including retinal artery occlusion (RAO) and retinal vein occlusion (RVO). Adjusted hazard ratio (aHR) of retinal vascular occlusion related to migraine was estimated. The cumulative incidences of subsequent retinal vascular occlusion, RAO, and RVO were significantly higher in migraine patients compared with controls (0.31% vs. 0.21%; 0.09% vs. 0.05%; 0.22% vs. 0.17%; all p < 0.001). The hazards of retinal vascular occlusion, RAO, and RVO were significantly greater in the migraine group (aHR, 1.69 [95% CI, 1.57, 1.83], 2.13 [95% CI, 1.84, 2.48] and 1.53 [95% CI, 1.40, 1.68], respectively). Risks of retinal vascular occlusion were significantly higher in migraine both with aura (MA) and without aura (MO) (aHR, 1.77 [95% CI, 1.58, 1.98], and 1.92 [95% CI, 1.64, 2.25]). Among patients with migraine, nonsteroidal anti-inflammatory drugs, propranolol, and flunarizine significantly reduce their risks of retinal vascular occlusion (aHR, 0.19 [95% CI, 0.16, 0.22], 0.73 [95% CI, 0.62, 0.86], 0.84 [95% CI, 0.76, 0.93]). Migraine, MA and MO are independently associated with higher risks of retinal vascular occlusion, RAO, and RVO.

Endoscopic Versus Microscopic Type I Tympanoplasty: An Updated Systematic Review and Meta-analysis.

OBJECTIVE: Our objective was to perform a systematic review and meta-analysis comparing the clinical outcomes after endoscopic and microscopic type I tympanoplasty. STUDY DESIGN: Randomized controlled trials, two-arm prospective studies, and retrospective studies were included. SETTING: Medline, Cochrane, EMBASE, and Google Scholar databases were searched until March 1, 2022 using the combinations of search terms: "endoscopic," "microscopic," and "tympanoplasty." METHODS: Two independent reviewers utilized the abovementioned search strategy to identify eligible studies. If any uncertainty existed regarding eligibility, a third reviewer was consulted. Primary outcome measures were graft success rate, air-bone gap (ABG) improvement, and operative time. Secondary outcomes were the rate of need for canalplasty, the proportion of self-rated excellent cosmetic results, and pain visual analog scale (VAS). RESULTS: Forty-three studies enrolled a total of 3712 patients who were undergoing type I tympanoplasty and were finally included. The pooled result showed endoscopic approach was significantly associated with shorter operative time (difference in means: -20.021, 95% confidence interval [CI]: -31.431 to -8.611), less need for canalplasty (odds ratio [OR]: 0.065, 95% CI: 0.026-0.164), more self-rated excellent cosmetic results (OR: 87.323, 95% CI: 26.750-285.063), and lower pain VAS (difference in means: -2.513, 95% CI: -4.737 to -0.228). No significant differences in graft success rate or ABG were observed between the two procedures. CONCLUSION: Endoscopic type I tympanoplasty provides a similar graft success rate, improvement in ABG, and reperforation rate to microscopic tympanoplasty with a shorter operative time, better self-rated cosmetic results, and less pain. Unless contraindicated, the endoscopic approach should be the procedure of choice in type I tympanoplasty.

Efficacy of Adjuvant Sublingual Immunotherapy After Septomeatoplasty.

BACKGROUND: The efficacy of adjuvant sublingual immunotherapy (SLIT) in correcting structural problems in patients with allergic rhinitis (AR) caused by mite who have undergone septomeatoplasty (SMP) has not been studied. METHODS: This non-randomized controlled study recruited patients with AR (caused by mite) and concurrent septal deviation and inferior turbinate hypertrophy, at a tertiary hospital in Taiwan. SMP was performed on all patients as a surgical intervention. The patients were then divided into two groups: the control group, which underwent surgery only, and the experimental group, which received SLIT as an adjuvant treatment. Demographic data and rhinitis control assessment test (RCAT) results were analyzed. RESULTS: A total of 96 patients were enrolled in the study (SMP + SLIT group, n = 52; SMP only group, n = 44). No significant differences were observed in any of the variables between the two groups before and one month after surgery. However, during evaluations at the third and sixth month, the SMP + SLIT group showed significant improvement in the total RCAT scores compared to the SMP only group (28.6 ± 1.56 vs. 24.5 ± 3.66, p < 0.001; 27.1 ± 2.87 vs. 19.9 ± 5.56, p < 0.001). In addition, significantly better control of all RCAT sub-categories was observed in the SMP + SLIT group at the third and sixth month evaluations. CONCLUSIONS: SLIT may serve as an ideal adjuvant therapy after SMP in patients with AR. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3073-3079, 2024.
