RESUMO
National cohort data collected during the coronavirus disease 2019 (COVID-19) delta and omicron periods in Korea revealed a lower risk of severe infection in recipients of three doses of the COVID-19 vaccine (adjusted odds ratio [aOR], 0.05-0.08). The risk of death was reduced during the omicron period compared to the delta period (aOR, 0.75; 95% confidence interval, 0.67-0.84).

We used a nationwide population registry in South Korea to estimate the effect of a second booster dose of mRNA COVID-19 vaccine on the risk for laboratory-confirmed SARS-CoV-2 infection, critical infection, and death in immunocompromised persons and long-term care facility (LTCF) residents. During February 16-May 7, 2022, among 972,449 eligible persons, 736,439 (75.7%) received a first booster and 236,010 (24.3%) persons received a second booster. Compared with the first booster group, at 30-53 days, the second booster recipients had vaccine effectiveness (VE) against all infections of 22.28% (95% CI 19.35%-25.11%), VE against critical infection of 56.95% (95% CI 29.99%-73.53%), and VE against death of 62.96% (95% CI 34.18%-79.15%). Our findings provide real-world evidence that a second booster dose of mRNA vaccine substantially increases protection against critical infection and death in these high-risk population groups.

PURPOSE: Sudden sensorineural hearing loss (SSNHL) is an otologic emergency. Despite multiple efforts to clarify the factors affecting the prognosis of severe-to-profound SSNHL, various studies showed inconsistent results and lack of clinical significance. Therefore, we examined the clinical features and outcomes of severe-to-profound SSNHL. MATERIALS AND METHODS: We included patients who experienced SSNHL between 2018 and 2021 and were diagnosed according to the American Academy of Otolaryngology-Head and Neck Surgery criteria; hearing loss over 70 dB on initial pure tone audiometry (PTA) was used to define severe-to-profound SSNHL. We retrospectively examine the demographic, laboratory, radiologic, and audiometric data of SSNHL patients. We also evaluated the final hearing gain of these patients by assessing their PTA findings and word-recognition scores. RESULTS: Of the 178 patients, 94 (52.81%) and 84 (47.19%) showed profound (>90 dB) and severe (>70 to 90 dB) hearing loss, respectively. The presence of vertigo and hypertension differed significantly between the severe and profound groups (p < 0.001 and p = 0.012, respectively), as did the initial serum creatinine level (p = 0.043). Recovery in PTA showed a reliable correlation with the interval between onset and treatment in the severe group and periventricular white-matter findings in the profound group (p < 0.001 and p = 0.011, respectively). The presence of hypertension was related to recovery of low tone (p = 0.023 for 250 Hz; p = 0.034 for 500 Hz), while glycated hemoglobin level was related to recovery of high tone in the severe group (p = 0.049 for 4000 Hz; p = 0.047 for 8000 Hz). CONCLUSIONS: Severe-to-profound SSNHL showed poor prognosis for hearing gain. The interval from onset to treatment was a significant prognostic factor for severe SSNHL, while the presence of vertigo, estimated glomerular filtration rate, and periventricular white-matter findings were significant prognostic factors for profound SSNHL.

BACKGROUND: Balloon eustachian tuboplasty (BET) is a minimally invasive surgical treatment that is effective and safe for obstructive eustachian tube dysfunction. However, BET complications include excessive widening of the eustachian tube, causing a patulous eustachian tube (PET). Herein, we report a case of PET following BET in a patient who underwent radiation therapy and reviewed the literature on considerations for reducing complications after BET. CASE PRESENTATION: A 63-year-old woman complained of bilateral ear fullness after concurrent chemoradiation therapy for nasopharyngeal lymphoma. BET was performed on the left side because the left-sided serous otitis media persisted. A left-sided PET was performed two weeks after the BET, along with eustachian tube silicone plug insertion on the left side. The patient became asymptomatic immediately after the surgery, with no recurrence reported after a 12-month follow-up period. CONCLUSIONS: To our knowledge, there has been no report of PET following BET in a post-radiation patient, and it was successfully treated via ET silicone plug insertion.

In November 2021, 14 international travel-related severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.529 (omicron) variant of concern (VOC) patients were detected in South Korea. Epidemiologic investigation revealed community transmission of the omicron VOC. A total of 80 SARS-CoV-2 omicron VOC-positive patients were identified until December 10, 2021 and 66 of them reported no relation to the international travel. There may be more transmissions with this VOC in Korea than reported.

The Mycobacterium tuberculosis H37Rv genome has been sequenced and annotated over 20 years ago, yet roughly half of the protein-coding genes still lack a predicted function. We characterized two genes of unknown function, rv3679 and rv3680, for which inconsistent findings regarding their importance for virulence in mice have been reported. We confirmed that a rv3679-80 deletion mutant (Δrv3679-80) was virulent in mice and discovered that Δrv3679-80 suffered from a glycerol-dependent recovery defect on agar plates following mouse infection. Glycerol also exacerbated killing of Δrv3679-80 by nitric oxide. Rv3679-Rv3680 have previously been shown to form a complex with ATPase activity and we demonstrate that the ability of M. tuberculosis to cope with elevated levels of glycerol and nitric oxide requires intact ATP-binding motifs in both Rv3679 and Rv3680. Inactivation of glycerol kinase or Rv2370c, a protein of unknown function, suppressed glycerol mediated toxicity in Δrv3679-80 Glycerol catabolism led to increased intracellular methylglyoxal pools and Δrv3679-80 was hypersusceptible to extracellular methylglyoxal suggesting that glycerol toxicity in Δrv3679-80 is caused by methylglyoxal. Rv3679 and Rv3680 interacted with Rv1509, and Rv3679 had numerous additional interactors including proteins of the type II fatty acid synthase (FASII) pathway and mycolic acid modifying enzymes linking Rv3679 to fatty acid or lipid synthesis. This work provides experimentally determined roles for Rv3679 and Rv3680 and stimulates future research on these and other proteins of unknown function.Importance A better understanding of the pathogenesis of tuberculosis requires a better understanding of gene function in M. tuberculosis This work provides the first functional insight into the Rv3679/Rv3680 ATPase complex. We demonstrate that M. tuberculosis requires this complex and specifically its ATPase activity to resist glycerol and nitric oxide toxicity. We provide evidence that the glycerol-derived metabolite methylglyoxal causes toxicity in the absence of Rv3679/Rv3680. We further show that glycerol-dependent toxicity is reversed when glycerol kinase (GlpK) is inactivated. Our work uncovered other genes of unknown function that interact with Rv3679 and/or Rv3680 genetically or physically, underscoring the importance of understanding uncharacterized genes.
RESUMO
OBJECTIVE: Sublingual immunotherapy (SLIT) has been considered as an effective and safe alternative to the subcutaneous route. However, different modalities and administration methods may lead to significant changes in their adherence and clinical outcomes. The purpose of this study was to compare the adherence, efficacy, and side effects of SLIT medicines: SLITone®, Lais®, and Staloral®. SUBJECTS AND METHODS: Eighty-two patients suffering from AR symptoms and sensitized only to house dust mite allergens were included. The patients were treated with SLITone®, Lais®, or Staloral®. Treatment outcomes related to efficacy, dropout rate, and adverse events were evaluated. The visual analogue scale (VAS) including sneezing, rhinorrhea, nasal obstruction, and itching was scored from 0 (normal) to 10 (severe), before and after SLIT. Dropout rate was defined as the number of patients who discontinue SLIT of oneself compared to the number of patients who receive SLIT. RESULTS: All of the nasal symptoms and total symptom scores were significantly decreased in SLITone®, Lais®, and Staloral®. Furthermore, there were significant difference in the improvement of rhinorrhea and TNSS between SLITone® and Staloral® group (p = 0.011 and p = 0.001, respectively). Four patients out of 26 in SLITone® group, 4 patients out of 30 in Lais® group, and 11 patients out of 26 in Staloral® group have stopped SLIT of themselves. The dropout rate was significantly higher in the Staloral® group than other two groups (p = 0.024). Only one patient complained adverse reaction such as swelling of mouth floor in the Staloral® group. CONCLUSION: Although all three SLIT medicines are effective in improving AR symptoms, the adherence to SLIT assessed in accordance with dropout rate was the lowest in the Staloral®.

BACKGROUND: Intraperitoneal isotonic saline instillation (SI) and pulmonary recruitment maneuver (RM) were indicated to alleviate post-laparoscopic shoulder pain (PLSP) effectively. The aim of this study was to compare the effects of the single strategy using SI alone and the combined strategy using SI and RM on PLSP reduction. METHODS: Subjects undergoing elective gynecologic laparoscopy were randomly allocated to a control group (no intervention, n = 48) and two intervention groups (single strategy of SI alone, n = 48; combined strategy of SI and RM, n = 48). In the control group, carbon dioxide was removed only via passive evacuation through the port sites at the completion of the laparoscopic procedure. In the saline instillation group, 20-mL/kg of body weight SI was performed. In the combined strategy group, RM using five pulmonary inflations was performed, in addition to SI. The PLSP scores, which were the primary outcome, were recorded using a visual analog scale postoperatively. RESULTS: The PLSP scores 24 and 48 h after surgery were significantly lower in the two intervention groups than in the control group (P = 0.014 and P = 0.001, respectively), while no significant differences were observed between the two intervention groups. CONCLUSIONS: The single strategy using SI alone is as effective as the combined strategy of SI and RM for removing residual carbon dioxide and consequently preventing PLSP. Therefore, considering the potential risks of pulmonary or hemodynamic complications associated with RM, the single strategy using SI alone might be a better choice than the combined strategy.

Background: Traditionally, minimum alveolar concentration (MAC) has been used as the standard measure to compare the potencies of volatile anesthetics. However, it reflects the spinal mechanism of immobility rather than the subcortical mechanism of analgesia. Recently, the surgical pleth index (SPI) derived from photoplethysmographic waveform was shown to reflect the intraoperative analgesic component. This study was designed to compare the SPI values produced by equi-MAC of two commonly used volatile anesthetics, sevoflurane and desflurane. Methods: Seventy-two patients undergoing arthroscopic shoulder surgery were randomly assigned to two groups receiving either sevoflurane (nâ =â 36) or desflurane (nâ =â 36). General anesthesia was maintained with the respective volatile anesthetic only. A vaporizer was adjusted to maintain end-tidal anesthetic concentration at age-corrected 1.0 MAC throughout the study period. The SPI value as an analgesic estimate and the bispectral index (BIS) value as a hypnotic estimate were recorded at predefined time points during the standardized surgical procedure. Results: During the steady state of age-corrected 1.0 MAC, mean SPI values throughout the entire study period were significantly higher in the sevoflurane group than in the desflurane group (38.1â ±â 12.8 vs. 30.7â ±â 8.8, respectively, Pâ =â 0.005), and mean BIS values were significantly higher in the sevoflurane group than in the desflurane group (40.7â ±â 5.8 vs. 36.8â ±â 6.2, respectively, Pâ =â 0.008). Conclusions: Equi-MAC of sevoflurane and desflurane did not produce similar surgical pleth index values. Therefore, sevoflurane and desflurane may have different analgesic properties at equipotent concentrations.

We investigated the combined moisturizing effect of liposomal serine and a cosmeceutical base selected in this study. Serine is a major amino acid consisting of natural moisturizing factors and keratin, and the hydroxyl group of serine can actively interact with water molecules. Therefore, we hypothesized that serine efficiently delivered to the stratum corneum (SC) of the skin would enhance the moisturizing capability of the skin. We prepared four different cosmeceutical bases (hydrogel, oil-in-water (O/W) essence, O/W cream, and water-in-oil (W/O) cream); their moisturizing abilities were then assessed using a Corneometer®. The hydrogel was selected as the optimum base for skin moisturization based on the area under the moisture content change-time curves (AUMCC) values used as a parameter for the water hold capacity of the skin. Liposomal serine prepared by a reverse-phase evaporation method was then incorporated in the hydrogel. The liposomal serine-incorporated hydrogel (serine level=1%) showed an approximately 1.62~1.77 times greater moisturizing effect on the skin than those of hydrogel, hydrogel with serine (1%), and hydrogel with blank liposome. However, the AUMCC values were not dependent on the level of serine in liposomal serine-loaded hydrogels. Together, the delivery of serine to the SC of the skin is a promising strategy for moisturizing the skin. This study is expected to be an important step in developing highly effective moisturizing cosmeceutical products.
RESUMO
OBJECTIVE: Hyperbaric oxygen therapy (HBOT) is an accepted treatment option for sudden sensorineural hearing loss (SSNHL), but it is still recommended in combination with corticosteroids. We investigated the efficacy of salvage HBOT in refractory SSNHL that does not respond to corticosteroid combination therapy. METHODS: Eighty-four patients were included, who had unilateral SSNHL with an improvement of pure-tone average (PTA) less than 10 dB after using intratympanic plus systemic corticosteroids (combined therapy) as the initial therapy. The control group (n = 66) received no further treatment, and the HBOT group (n = 18) received additional treatment with HBOT (10 sessions in total with 2.5 atmospheres absolute for 1 hour). RESULTS: No differences in PTA or WDS were found between the 2 groups. However, the mean hearing gain in the HBOT group (16.8 ± 4.49 dB) was significantly higher than that in the control group (4.45 ± 1.03 dB) (P = .015). The proportion of patients with hearing recovery (hearing gain of 10 dB or more) after treatment was significantly higher in HBOT group (38.9%) than in the control group (10.6%). CONCLUSIONS: In patients with refractory SSNHL after steroid combined therapy, salvage HBOT showed a significant effect on hearing gain and recovery rate.

OBJECTIVES: The operating microscope (OM) commonly used in ear surgeries has several disadvantages, including a low depth of field, a narrow field of view, and unfavorable ergonomic characteristics. The exoscope (EX) was developed to overcome these disadvantages. Herein, we compared OM and EX during mastoidectomy and found out the feasibility of the EX. STUDY DESIGN: Prospective randomized comparative study. SETTING: Tertiary academic medical center. PATIENTS: Patients who had mastoidectomy for chronic otitis media with or without cholesteatoma between January 2022 and April 2022. INTERVENTION: Canal wall-up mastoidectomy (CWUM) or canal wall-down mastoidectomy (CWDM) using OM or EX without endoscope. MAIN OUTCOME MEASURES: Operative setting time (the time between the end of general anesthesia and incision), operative time (from incision to suture), postoperative audiologic outcomes, perioperative complications, and the decision to switch from EX to OM. RESULTS: Of 24 patients who were diagnosed with chronic otitis media or cholesteatoma, 12 each were randomly assigned to the OM or EX group. The mean operation time was 175 ± 26.5 minutes and 172 ± 34.6 minutes in the EX and OM group, respectively, which was not significantly different ( p = 0.843). The procedures in the EX group were successfully completed using a three-dimensional (3D)-EX without conversion to OM. All surgeries were completed without any complications. The postoperative difference in the air and bone conduction was 11.2 and 12.4 dB in the EX and OM groups, respectively, which was not significantly different ( p = 0.551). CONCLUSIONS: EX is comparable to OM in terms of surgical time, complications, and audiologic outcomes following mastoidectomy. The EX system is a potential alternative to OM. However, further improvements are required to overcome some drawbacks (deterioration of image resolution at high magnification, requirement of an additional controller for refocusing).

BACKGROUND: Severe fever with thrombocytopenia syndrome (SFTS) has no vaccine or treatment and an extremely high fatality rate. We aimed to analyze and evaluate the risk factors for death associated with SFTS. METHODS: Among reports from 2018 to 2022, we compared and analyzed 1,034 inpatients aged 18 years or older with laboratory-confirmed SFTS who underwent complete epidemiological investigations. RESULTS: Most of the inpatients with SFTS were aged 50 years or older (average age, 67.6 years). The median time from symptom onset to death was 9 days, and the average case fatality rate was 18.5%. Risk factors for death included age of 70 years or older (odds ratio [OR], 4.82); agriculture-related occupation (OR, 2.01); underlying disease (OR, 7.20); delayed diagnosis (OR, 1.28 per day); decreased level of consciousness (OR, 5.53); fever/chills (OR, 20.52); prolonged activated partial thromboplastin time (OR, 4.19); and elevated levels of aspartate aminotransferase (OR, 2.91), blood urea nitrogen (OR, 2.62), and creatine (OR, 3.21). CONCLUSION: The risk factors for death in patients with SFTS were old age; agriculture-related occupation; underlying disease; delayed clinical suspicion; fever/chills; decreased level of consciousness; and elevated activated partial thromboplastin time, aspartate aminotransferase, blood urea nitrogen, and creatine levels.
RESUMO
OBJECTIVE: This study aimed to determine the optimal protocol of hyperbaric oxygen therapy (HBOT) according to various treatment settings for sudden sensorineural hearing loss (SSNHL). METHODS: A 112 patients with SSNHL were enrolled in this prospective study. All patients were treated with systemic steroid therapy, intratympanic steroid therapy, and HBOT. According to the pressure and duration of HBOT (10 sessions in total), the patients were divided into three groups: group 1, 2.5 atmospheres absolute (ATA) for 1 h; group 2, 2.5 ATA for 2 h; and group 3, 1.5 ATA for 1 h. The pure-tone average (PTA), word discrimination score (WDS), and mean gain were compared. RESULTS: A total of 105 patients completed the 3-month follow-up, and 6 patients were excluded. Differences among groups were found in PTA, WDS, and mean gain. In the post-hoc analysis, group 3 had significantly lower WDS and mean gain than groups 1 and 2; however, group 2 showed no significant differences from group 1. The proportion of patients with hearing recovery after treatment was significantly higher in group 1 (57.6%) and group 2 (58.8%) than in group 3 (31.3%). CONCLUSIONS: When HBOT (10 sessions) was combined with corticosteroids as the initial therapy for SSNHL, a higher pressure (1.5 ATA vs. 2.5 ATA) provided better treatment results; however, increasing the duration (1 h vs. 2 h) under 2.5 ATA did not result in a significant difference. Therefore, HBOT for SSNHL may be performed at 2.5 ATA for 1 h in 10 sessions. Laryngoscope, 133:383-388, 2023.

BACKGROUND: Using reliable measurement tools is becoming increasingly important as the prevalence of obesity among children increases in Korea. The Dutch Eating Behavior Questionnaire for Children (DEBQ-C) measures three eating behaviors associated with overeating. This study aims to validate the DEBQ-C for use among Korean children and adolescents with high body weight. It examines the psychometric features of the Korean translation of the DEBQ-C and investigates the relationship between the subscale scores of the DEBQ-C and the weight status of participants (categorized into overweight, obese, and morbidly obese). METHODS: A total of 233 children and adolescents (mean age: 11.4 ± 1.6 years) completed the questionnaire. The study verified the factor structure of the DEBQ-C using confirmatory factor analysis (CFA) and estimated its internal consistency with Cronbach's alpha. For convergent validity, it employed Pearson's correlation coefficient to assess relationships between the three eating behaviors of the DEBQ-C and the number of food addiction symptoms of the Yale Food Addiction Scale for Children (YFAS-C). Lastly, it examined the relationship between DEBQ-C scores and weight status via multinomial logistic regression analysis. RESULTS: The three-factor model demonstrated goodness-of-fit (χ2 = 253, df = 167, χ2/df = 1.515, p < 0.001, CFI = 0.944; TLI = 0.937; RMSEA = 0.047). The internal consistency of the three eating behaviors was also satisfactory (Cronbach's alpha = 0.707-0.890). The emotional and external eating subscales of the DEBQ-C were positively correlated with the number of symptoms of food addiction of the YFAS-C. Emotional (OR: 2.008; 95% CI 1.973-2.043) and external (OR: 2.074; 95% CI 2.029-2.119) eating were positively associated with obesity status. CONCLUSION: The results suggest that the Korean version of the DEBQ-C is suitable for the examination of problematic eating behaviors in Korean children and adolescents with high body weight.
The proportion of children and adolescents with obesity in Korea is increasing. Thus, the availability of a tool that can reliably identify problematic eating behavior linked to obesity would assist with prevention and management efforts. The Dutch Eating Behavior Questionnaire for Children (DEBQ-C) measures three types of overeating behavior in children that influence weight gain. This study examines the suitability of the Korean translation of the DEBQ-C questionnaire for use in studies on Korean children and adolescents with high body weight. The results of a survey on 233 adolescents (average age: 11.4 ± 1.6 years) suggest that the DEBQ-C translation would be useful in investigating overeating behavior in Korean children and adolescents. In addition, the findings suggest that eating in response to emotions and external cues are likely to play a role in the development of obesity among children and adolescents.
