ABSTRACT

Objective:This study aimed to compare the effects of cochlear implantation（CI） on vestibular function in patients with large vestibular aqueduct syndrome（LVAS） and in patients with extremely severe deafness with normal inner ear structure. Methods:A total of 28 LVAS patients and 28 patients with normal inner ear structure who suffered from extremely severe deafness were selected. The parameters of caloric tests, bone conduction evoked cervical vestibular-evoked myogenic potentials（cVEMP）, bone conduction evoked ocular vestibular-evoked myogenic potentials（oVEMP） and video head impulse tests（v-HIT） were compared between the two groups before and after CI. The data were analyzed using SPSS 26.0 software. Results:There was no significant difference in the results of the preoperative caloric test, v-HIT, and oVEMP（P1, N1） between the LVAS group and the control group（P>0.05）. Compared to the control group, the LVAS group exhibited a shorter cVEMP P1[（13.41±0.71）ms vs （16.28±0.89）ms, P<0.000 1], shorter N1[（19.83±0.54）ms vs （28.18±1.56）ms, P<0.000 1], higher amplitude[（123.60±83.80）μV vs （73.92±79.85）μV, P=0.049 4] and higher oVEMP amplitude[（16.60±13.87）μV vs （9.96±10.47）μV, P=0.028 5] before CI. The abnormal rate of caloric test increased in both groups after CI（25.00% vs 57.14%, P=0.028 8, 32.14% vs 82.14%, P=0.000 3, respectively）. There was no significant difference in the v-HIT parameters in both groups before and after the operation. As for the LVAS group, there was no statistically significant difference in cVEMP and oVEMP induction rates before and after operation. In the control group, there was a decrease in cVEMP induction rate（96.42% vs 64.28%, P=0.005 2） and oVEMP induction rate（96.42% vs 57.14%, P=0.000 9） after CI. LVAS group showed a shorter cVEMP P1[（13.41±0.71）ms vs （10.30±0.60）ms, P<0.000 1]; shorter cVEMP N1[（19.86±0.53）ms vs （18.97±1.33）ms, P=0.004 7]; decreased amplitude[（124.50±84.86）μV vs （64.35±61.57）μV, P=0.001 0] and shorter oVEMP amplitude[（15.92±13.03）μV vs （9.16±9.20）μV, P=0.009 9] after CI. The oVEMP N1 in the control group was longer than that before operation[（11.73 ± 0.91）ms vs （13.35 ± 2.60）ms, P=0.019 6], whereas there was no significant difference in other VEMP parameters after CI. Conclusion:Before CI, there was no significant difference in the results of the caloric test and v-HIT between the LVAS group and the control group, but the LVAS group exhibited increased sensitivity to acoustic stimulation-induced myogenic potentials. After CI, the function of the semicircular canal was impaired in both groups in the low-frequency area, and remained largely unaffected in the high-frequency area. Additionally, the function of the otolith in the LVAS group was less affected than that in the control group after CI, which may be related to the fact that the enlarged vestibular aqueduct of the LVAS patients acted as the third window of the inner ear.

ABSTRACT

Objective:To explore the feasibility of the multiple-choice auditory graphical interactive check（MAGIC） screening module in childhood hearing screening in children aged 3 to 6 years. Methods:A hearing screening was conducted on 366 children（732 ears） aged between 3 and 6 years. The screening methods included MAGIC, DPOAE, and acoustic immittance.The cooperation, screening time, pass rate, and correlation of the three screening methods were compared. Results:There was a statistically significant difference in the degree of cooperation among the three screeningmethods（P=0.004）.The MAGIC pure tone screening method was 98.6%, the screening DPOAE was 99.5%,and the acoustic immittance screening was 100%. For the screening duration, the MAGIC pure tone screening method was（116.3±59.1）s, the screening DPOAE was（27.2±19.7）s, and the acoustic impedance screening was（24.6±14.6）s. There was a significant statistical significance differences among the three or two groups（P<0.01）. The passing rates of MAGIC pure tone screening,screening DPOAE and acoustic immittance screening were 64.7%, 65.4%, and 69.3%, respectively, and there was no significant statistical difference among the three or two groups（P>0.05）. There was no significant difference between MAGIC pure tone screening method and screening DPOAE（P=0.827>0.05）, and acoustic impedance（P=0.653>0.05）, while the difference between screening DPOAE and acoustic impedance was statistically significant（P<0.01）. Conclusion:MAGIC pure sound screening method has good feasibility, can comprehensively reflect the hearing level of screened children, and can be promoted for hearing screening in children aged between 3 and 6 years.

ABSTRACT

PURPOSE: To investigate the protective effect of sub-hypothermic mechanical perfusion combined with membrane lung oxygenation on ischemic hypoxic injury of yorkshire brain tissue caused by traumatic blood loss.

METHODS: This article performed a random controlled trial. Brain tissue of 7 yorkshire was selected and divided into the sub-low temperature anterograde machine perfusion group (n = 4) and the blank control group (n = 3) using the random number table method. A yorkshire model of brain tissue injury induced by traumatic blood loss was established. Firstly, the perfusion temperature and blood oxygen saturation were monitored in real-time during the perfusion process. The number of red blood cells, hemoglobin content, NA⁺, K⁺, and Ca²⁺ ions concentrations and pH of the perfusate were detected. Following perfusion, we specifically examined the parietal lobe to assess its water content. The prefrontal cortex and hippocampus were then dissected for histological evaluation, allowing us to investigate potential regional differences in tissue injury. The blank control group was sampled directly before perfusion. All statistical analyses and graphs were performed using GraphPad Prism 8.0 Student t-test. All tests were two-sided, and p value of less than 0.05 was considered to indicate statistical significance.

RESULTS: The contents of red blood cells and hemoglobin during perfusion were maintained at normal levels but more red blood cells were destroyed 3 h after the perfusion. The blood oxygen saturation of the perfusion group was maintained at 95% – 98%. NA⁺ and K⁺ concentrations were normal most of the time during perfusion but increased significantly at about 4 h. The Ca²⁺ concentration remained within the normal range at each period. Glucose levels were slightly higher than the baseline level. The pH of the perfusion solution was slightly lower at the beginning of perfusion, and then gradually increased to the normal level. The water content of brain tissue in the sub-low and docile perfusion group was 78.95% ± 0.39%, which was significantly higher than that in the control group (75.27% ± 0.55%, t = 10.49, p < 0.001), and the difference was statistically significant. Compared with the blank control group, the structure and morphology of pyramidal neurons in the Prefrontal cortex and CA1 region of the hippocampal gyrus were similar, and their integrity was better. The structural integrity of granulosa neurons was destroyed and cell edema increased in the perfusion group compared with the blank control group. Immunofluorescence staining for glail fibrillary acidic protein and Iba1, markers of glial cells, revealed well-preserved cell structures in the perfusion group. While there were indications of abnormal cellular activity, the analysis showed no significant difference in axon thickness or integrity compared to the 1-h blank control group.

CONCLUSIONS: Mild hypothermic machine perfusion can improve ischemia and hypoxia injury of yorkshire brain tissue caused by traumatic blood loss and delay the necrosis and apoptosis of yorkshire brain tissue by continuous oxygen supply, maintaining ion homeostasis and reducing tissue metabolism level.

ABSTRACT

OBJECTIVES: To evaluate the self-etch bonding potential of universal adhesive systems with varying acidic compositions by analyzing the wettability properties, topographical change, and microshear bond strength (µSBS) to enamel.

METHODS: Eight universal adhesives were tested: All-Bond Universal (Bisco), Ambar Universal (FGM), Gluma Bond Universal (Kulzer), OptiBond Universal (Kerr), Peak Universal Bond (Ultradent), Prime&Bond Universal (Dentsply), Singlebond Universal (3 M ESPE), and Tetric N-Bond Universal (Ivoclar). Bovine incisors were prepared and treated with each adhesive according to the manufacturer’s instructions. The following tests were carried out: contact angle to measure the adhesives’ wetting ability; optical profilometry to evaluate the topographical changes obtained with adhesives’ application; energy dispersive X-ray spectroscopy (EDX) to quantify the removal of inorganic elements from enamel; and µSBS to verify the bonding potential of adhesives to enamel. Statistical analyzes included ANOVA, Kruskal-Wallis, Weibull analysis, Pearson correlation, and chi square test (α=0.05).

RESULTS: Significant differences were found in contact angles immediately after adhesive application and after 30 s, with Gluma Bond Universal and Tetric N-Bond Universal showing the lowest (the best wetting ability) and the highest values (the lowest wetting ability), respectively. EDX revealed varying degrees of Ca and P reduction, with Gluma Bond Universal resulting in the greatest Ca and P reduction from enamel (∼65 % and ∼62 % reduction, respectively. Topographical analysis indicated significant changes in roughness, mainly for Gluma Bond Universal. The µSBS mean values ranged from 14.7 MPa (Ambar Universal) to 26.8 MPa (Tetric N-Bond Universal). OptiBond Universal and Tetric N-Bond Universal exhibited the highest resin-enamel bonds. Weibull analysis was performed to better understand the bonding reliability of the tested adhesives, with OptiBond Universal demonstrating increased modulus and characteristic strength, performing as one of the most interesting compositions for enamel bonding. Adhesives based on carboxylic acids were more acidic than adhesives containing phosphate-based monomers (p = 0.033), and the removal of Ca and P elements from enamel was more intense with the use of adhesives based on carboxylic acids (p = 0.029). There was a strong relationship between the Sz values of adhesively treated enamel and the baseline contact angle (wettability) of adhesives (R² = -0.771; p = 0.025).

SIGNIFICANCE: The study highlights significant variability among universal adhesives in terms of their interaction with enamel. Adhesives based on GPDM (OptiBond Universal) and 10-MDP (Tetric N-Bond Universal) demonstrated the best bonding performance, suggesting they may be preferable in clinical settings where strong and reliable enamel bonds are critical. The presence of 10-MDP was not significantly associated with improved dental bonds. The present findings provide valuable information for dentists in selecting adhesives that optimize clinical outcomes in enamel substrate using the self-etching adhesive approach.

ABSTRACT

AIM: To evaluate predictive chest computed tomography (CT) findings associated with the development of adult T-cell leukemia/lymphoma (ATLL) in human T-lymphotropic virus type I (HTLV-1) carriers.

MATERIALS AND METHODS: This retrospective study examined 171 adult T-cell leukemia/lymphoma and 158 HTLV-1 carriers who were treated from November 2004 to April 2021. The radiological features of 888 chest CT scans in total were retrospectively assessed by two chest radiologists who were unaware of the underlying diagnoses and compared between the groups.

RESULTS: In patients with aggressive type ATLL (acute type and lymphoma type), lymph node enlargement was the most frequently observed abnormality (65.2%), followed by ground-glass opacity (33.3%) and pleural effusion (30.4%). In patients with indolent type (chronic type and smoldering type), lymph node enlargement, and bronchiectasis were the most frequently observed abnormalities (5.6% and 5.6%, respectively). In each type, centrilobular nodules were observed in none and in one patient, respectively. In the 158 HTLV-1 carriers, centrilobular nodules (n = 62; 39.2%) were the most frequently observed abnormality. Centrilobular nodules were significantly frequently observed in HTLV-1 carriers compared with ATLL patients. No HTLV-1 carrier with centrilobular nodules on CT developed ATLL during the duration of care. A comparative analysis between CT scans performed before ATLL development in ATLL patients and those of HTLV-1 carriers showed that no centrilobular nodules were observed on the pre-ATLL CT scans, and a statistically-significant difference in centrilobular nodules was found between these two groups.

CONCLUSION: The presence of centrilobular nodules may be an indicative CT finding in HTLV-1 carriers who are less likely to develop ATLL.

ABSTRACT

INTRODUCTION: Primary hyperparathyroidism (PHPT) is more prevalent in populations with obesity. Obesity-related vitamin D deficiency may affect rates of multigland parathyroid disease, but this relationship is less clear. We aimed to assess the relationship between obesity and the rate of multigland disease in patients with PHPT.

METHODS: Patients who underwent parathyroidectomy from 2015 to 2021 for sporadic PHPT at a tertiary center were retrospectively analyzed. The primary outcome was rates of single-gland versus four-gland parathyroid hyperplasia in relation to obesity. Secondary outcomes included analysis of serum biochemistries [parathyroid hormone (PTH), calcium, 25(OH) vitamin D (25OHD)] before and 6 mo postoperatively based on obesity classification: no obesity (body mass index [BMI] <30 kg/m²), Class 1 (BMI 30-34.9 kg/m²), Class 2 (BMI 35-39.9 kg/m²), Class 3 (BMI ≥40 kg/m²). Statistical analysis was performed using Chi-square, Mann-Whitney U, and Kruskal-Wallis tests where applicable.

RESULTS: Of 2634 patients who underwent parathyroidectomy, a total of 1173 had obesity. Obesity did not confer any differences in the proportion of four-gland versus single-gland hyperplasia (25 versus 26%, P = 0.79). Compared to patients without obesity, preoperative PTH levels were higher in patients with Class 2 [86 (interquartile range [IQR] 66-118) versus 95 (IQR 70-137) pg/mL, P = 0.001] and Class 3 [86 (IQR 66-118) versus 104 (76-150) pg/mL, P < 0.001] obesity. Conversely, 25OHD before surgery was lower across obesity subclasses [no obesity: 36.0 (25.3-49.3), Class 1: 32.5 (24.0-46.0), Class 2: 32.9 (22.0-44.6), Class 3: 31.7 (20.4-45.0) ng/mL, P < 0.001]. Postoperative PTH and 25OHD improved in all cohorts. No calcium-related differences were found among patients based on obesity classification.

CONCLUSIONS: Obesity is not associated with an increased rate of four-gland hyperplasia in patients with PHPT, and therefore should not alter surgical management. The levels of 25OHD in patients with obesity should be monitored for vitamin deficiency preoperatively and postoperatively.

Methods: One hundred and thirty two eight women with BC were enrolled in this research based on inclusion and exclusion criteria and were randomized into group A and B. Group A received breast cancer (BC) support group therapy whereas group B received multi-component exercise program. Waist Hip ratio (WHR), Body Mass Index (BMI), Circumference measurement and Functional Assessment of Cancer Therapy Breast (FACT-B) scale were employed as outcome measures. To validate the outcomes, pre- and post-assessments of the mentioned measures were conducted. Statistical evaluation was conducted with SPSS statistical software (version 26.0).

RESULTS: The findings revealed considerable improvement among the group for homolateral and contralateral arm and forearm, right and left thigh and right and left leg circumference (p=0.0087,0.0162, 0.0061, 0.0048, 0.0266,0.0142,0.0364, 0.0021), FACT-B (p=0.008, 0.002, 0.007,0.01,0.001,<0.0001), conversely no significant enhancement was observed for BMI (p=0.743) and WHR (p=0.6614) of patients undergoing multi-component exercise as compared to other group. Also, significant improvement between the groups was observed for circumference(0.0478,0.0305,0.0279,0.0240,0.0374,0.0293,0.0420,0.0334,0.0449,0.0260,0.0412 ,0.0160,0.0454,0.0324,0.0375,0.0214), FACT-B (0.51, 0.045, 0.313, 0.238, 0.593, 0.049, 0.405, <0.0001, 0.190, 0.015,0.131,0.176,0.006,<0.0001), conversely no significant enhancement was observed for BMI (p=0.9634, 0.364), WHR (p=0.988, 0.915) at post treatment 6 month and 1 year.

CONCLUSION: The study concluded that multi-component exercise program had shown a significant effect on body composition and PWB, EWB, SWB among BCS.

ABSTRACT

OBJECTIVE: Aim of the study was to evaluate and compare the prevalence female sexual dysfunction (FSD) in cervical cancer (CC) survivors to a healthy female population.

MATERIALS AND METHODS: This observational prospective trial was conducted at Thammasat University Hospital, Thailand, between April 2023 and February 2024. Participants were CC survival who attended an outpatient cancer clinic. Subject with age between 30 and 60 years old and engaged in sexual intercourse at least once within the last 4 weeks were recruited. The control group was women who attended outpatient gynecologic clinic for routine pelvic examination with no serious medical diseases and no malignancy. The female sexual function index (FSFI) was applied to all the participants during the survey. Other demographic data of the participants were collected.

RESULTS: A total of 116 cases were enrolled in the study. Participants were equally divided into the study and control groups. The mean age and BMI of participants were 49.4 years and 24.7 kg/m², respectively without statistical significance. The FSD’s prevalence of the CC survival was significantly higher than control group (34.5 and 10.4 percent, respectively). CC survivors reported significantly poorer outcomes in the domains of lubrication, sexual satisfaction, and pain compared to the control group.

CONCLUSION: The prevalence rates of CC survival and control group was 34.5 and 10.4 percent, respectively. Three out of six FSFI domains namely lubrication, satisfaction, and pain showed more problematic for CC survivors compared to control group.

ABSTRACT

BACKGROUND: Cancer screening is a crucial component in the fight to reduce cancer incidence and mortality. Currently, the WHO recommends highly effective cancer screening programs, including screening for cervical cancer (CC), breast cancer (BC), and colorectal cancer (CRC). Despite the implementation of a cancer screening program since 2014, an evaluation of the effectiveness of BC, CC, and CRC screening in the Kazakhstan has not yet been conducted. Study aimed to assess the effectiveness and coverage of BC, CC, and CRC screening in the Republic of Kazakhstan during the period from 2021 to 2023.

METHODS: Data for the retrospective analysis were extracted from the “Healthcare Statistics” database. Data on participants eligible for screening (n=8,167,184) for BC, CC, and CRC were included in the analysis.

RESULTS: In 2023, there was a noticeable decrease in the number of detected cases of CC (1.7) compared to previous years. The detection rates for BC (14) and CRC (around 1) per 100,000 population in 2023 remained almost at the same level as in previous years. The detection rate for BC was 0.74% in 2021, followed by a decline to 0.59% in 2022. In 2023, there was an increase to 1.69%. As for CC, the detection rate was 0.70% in 2021, it increased to 0.77% in 2022, but then decreased again to 0.53% in 2023. CRC shows a steady decline in detection rates. In 2021, the detection rate was 4.23%, then it dropped to 3.64% in 2022, and continued to decrease to 3.28% in 2023.

CONCLUSIONS: The data for 2021-2023 underscore the necessity for continuous monitoring, analysis, and adaptation of screening strategies, taking into account regional peculiarities and new challenges, such as the pandemic. Ensuring high screening coverage for BC, CC, and CRC is a key factor for the early detection and effective treatment of these diseases.
