Early Identification and Management of Congenital Cytomegalovirus

xlomafota13 shared this article with you from Inoreader Early Identification and Management of Congenital Cytomegalovirus Via Otolaryngologic Clinics of North America Congenital cytomegalovirus (cCMV) is the most common nongenetic cause of sensorineural hearing loss. Despite its prevalence, universal screening for cCMV is not currently performed. Hearing loss caused by cCMV is most often severe to profound, often bilateral, and may be fluctuating or progressive. Infants with hearing loss at birth and confirmed cCMV might benefit from antiviral therapy. Roughly half of hearing loss cases owing to cCMV are delayed in onset, and consequently, these children pass newborn hearing screening. Children with cCMV require close audiologic monitoring, require appropriate management with hearing aids, and should be monitored for cochlear implant candidacy. View on the web Inoreader.

Normal anatomy, variants and factors associated with the cervical vagus nerve topography: a high-resolution ultrasound study

xlomafota13 shared this article with you from Inoreader Normal anatomy, variants and factors associated with the cervical vagus nerve topography: a high-resolution ultrasound study Via radiol anat Surg Radiol Anat. 2021 Sep 15. doi: 10.1007/s00276-021-02832-4. Online ahead of print. ABSTRACT PURPOSE: To describe the cervical vagus nerve (CVN) topography at the thyroid lobe (TL) level using high-resolution ultrasound and to investigate the possible association with anthropometric data, TL size, and thyroid disease. METHODS: We prospectively examined 550 CVNs in 275 (205 female, 70 male) individuals with normal thyroid (53/275, 19.3%), multinodular disease (167/27 5, 60.7%), and Hashimoto thyroiditis (55/275, 20%). The CVN location relative to the common carotid artery was recorded as typical (lateral position) and atypical (anterior, medial, and posterior position). The shortest distance between CVN and TL margin, the TL dimensions, and volume were measured. RESULTS: Normal thyroid subjects had lateral-positioned right CVNs in 100% and lateral/anterior/medial left CVNs in 81.1%, 15.1%, and 3.8%, respectively. CVN types did not differ significantly bilaterally between study groups. Asymmetry in CVN topography in all subjects was found in 22.2%, of which anterior CVN was the most common atypical position (64%), especially on the left side (82%). Significant gender, age, body mass, and BMI differences among CVN types were observed on the left side only. Among CVN types, no difference in TL dimensions, volume, and CVN-TL distance was found in all study groups. A weak negative correlation was recorded between CVN-thyroid distance and TL vol ume only on the left side (r = - 0.147, p = 0.01). CONCLUSION: Asymmetry in CVN topography is mainly due to the increased incidence of the anterior location of CVN on the left side. Age and anthropometric parameters are different on the left side possibly due to the increased prevalence of left CVN variants.

xlomafota13 shared this article with you from Inoreader The development of auditory speech perception and spatial hearing abilities within one year after cochlear implantation in preschool prelingual deaf children Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Aug 7;56(8):812-818. doi: 10.3760/cma.j.cn115330-20200925-00771. ABSTRACT Objective: To investigate the development of auditory speech perception and spatial hearing abilities within one year after cochlear implantation in preschool prelingual deaf children and the relationship between the two abilities. Methods: This retrospective study analyzed 31 preschool children with an average age of (2.3±1.2) years. All cases were assessed at pre-implant, 6 months and 12 months post-implant using the Infant-toddler Meaningful Auditory Integration Scale (IT-MAIS), the Meaningful Auditory Integration Scale (MAIS) and the Mandarin Early Speech Perception test (MESP) to evaluate their listening and speech perception abilities, and using the Speech,Spatial,and Other Qualities of Hearing Scale for Parents (SSQ-P) questionnaires to evaluate their speech perception and spatial hearing a bilities. SPSS 23.0 was used for the statistical analysis. Results: All children performed better at 6 months and 12 months post-implant with IT-MAIS/MAIS, MESP than pre-implant, and the scoring rate continued to improve, with a significant difference (P<0.01). For the SSQ-P (Speech) and SSQ-P (Spatial) scores, the mean scores of pre-implant were (0.9±0.2) points and (0.8±0.3) points, those of 6 months post-implant were (4.6±0.2) and (2.6±0.3), and 12 months post-implant were (6.2±0.2) and (6.3±0.3), the scores of the two groups were significantly different at pre-implant, 6 months and 12 months post-implant (P<0.01). The growth rate of SSQ-P (Spatial) from pre-implant to 12 months post-implant was 675.3%, and the growth rate from 6 months post-implant to 12 months post-implant was 140.6%, the growth rate showed an significant increase compared with IT-MAIS/MAIS, MESP and SSQ-P (Speech).SSQ-P (Speech) and SSQ-P (Spatial) scores were moderate correlat ion at 12 months post-implant(r=0.465, P=0.008). Conclusions: Within one year after cochlear implantation, listening, speech perception and spatial hearing abilities of preschool prelingual deaf children could show a comprehensive, continuous and significant progress as the implantation time increasing. The growth rate of spatial hearing is greater than that of speech perception at 12 months post-implant, and the spatial hearing could still show rapid development characteristics after 6 months post-implant.

Studies on efficacy of a bioabsorbable steroid-eluting sinus stent in the frontal sinus opening of chronic rhinosinusitis with nasal polyps

xlomafota13 shared this article with you from Inoreader Studies on efficacy of a bioabsorbable steroid-eluting sinus stent in the frontal sinus opening of chronic rhinosinusitis with nasal polyps Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Aug 7;56(8):824-829. doi: 10.3760/cma.j.cn115330-20200809-00655. ABSTRACT Objective: To assess the efficacy of a bioabsorbable steroid-eluting sinus stent in improving surgical outcomes when placed in the frontal sinus ostium (FSO) following full endoscopic sinus surgery (ESS) in patients with whole group chronic rhinosinusitis with nasal polyps (CRSwNP). Methods: Patients with whole group CRSwNP who had similar lesions on bilateral sinus between September 2019 and March 2020 in Department of Otorhinolaryngology Head and Neck Surgery, Shanghai Changhai Hospital were chosen. Patients with CRSwNP who underwent extended ESS were randomly assigned to receive a steroid-eluting sinus stent in one FSO whereas the contralateral side received surgery alone. Endoscopic evaluations recorded at 30, 90 days postoperative were graded by an independent assessment panel to assess the ne ed for interventions in the FSO. Semi-quantitative data with CT and endoscopic score were performed by rank sum test. The need for postoperative intervention and the patency rate of FSO were analyzed using the McNemar test. Results: Thirty-one patients with whole group CRSwNP met all eligible criteria, including 17 males and 14 females, with the age of (44.5±11.8) years(x¯±s). Stents were successfully placed in one FSO of all patients. At 30 days post-ESS, the assessment panel reported that steroid-eluting stents reduced the need for postoperative interventions by 41.0% (χ2=5.314,P=0.021), the need for oral steroid interventions by 40.0% (χ2=4.133,P=0.042) and the need for surgical interventions by 74.8% (χ2=4.292,P=0.038) compared to control sinuses with no stents. Clinical surgeons also reported greater diameter of FSO compared to control sinuses at 30 days post-ESS (74.2% vs 48.4%, χ2=4.351, P=0.037). These results at 90 days post-ESS were consistent with those at 30 days post-ESS. Conclusion: Bioabsorbable steroid-eluting sinus stents in the FSO can reduce polyp formation, adhesion, and the need for postoperative interventions in FSO of CRSwNP patients and improve the early postoperative outcomes.

ABSTRACT Objective: To analyze the clinical features of patients with odontogenic sinusitis (OS) treated by endoscopic sinus surgery (ESS). Methods: A retrospective investigation was carried out in our 27 (16 males and 11 females) cases with OS aged (49.74±14.42) years old. Subjects were hospitalized between January 2018 and November 2020 from Department of Otorhinolaryngology Head and Neck Surgery, Beijing Chaoyang Hospital. The medical history, symptoms, result of nasal endoscopy and paranasal sinus computed tomography (CT) were analyzed statistically by SPSS 19.0. Results: OS mainly occured on unilateral sinuses, with a duration of (8.56±11.79) months. Seventy point four percent (19/27) of the patients had a course within six-month, only 11% was over 12 months (3/27). Symptoms mostly showed as n asal obstruction (88.9%; 24/27), runny nose (81.5%; 22/27), nasal stinks (16/19) and postnasal drip (10/10). Sixty-three percent (17/27) of the OS patients had a dental history. Nasal endoscopic examination revealed a swelling of the ostiomeatal complex (77.8%; 21/27), medial wall interhal displacement of maxillary sinus (55.6%; 15/27), white emulsion-like purulent secretion in the middle meatus (70.4%; 19/27) and nasal polyps (59.3%; 16/27). Etiology of OS included implant-related problems (14.8%; 4/27) and periodontal disease (85.2%; 23/27). Conclusions: OS is usually unilateral sinusitis with a short history. Its clinical features show nasal stinks, white emulsion-like purulent secretion in the middle meatus and imaging findings of unilateral maxillary sinusitis with tooth-related lesions.

ABSTRACT Objective: To explore the values of intraoperative fine-needle aspiration (IFNA) and parathyroid hormone (PTH) detection in the eluate of aspirated tissue during parathyroidectomy. Methods: Fifty-four patients with secondary hyperparathyroidism (SHPT) including 24 males and 30 females, aged 20-83 years, admitted to Zhongnan Hospital of Wuhan University from January 2019 to October 2019, were included. All patients received subtotal parathyroidectomy with autologous transplantation, during surgery, IFNA and PTH detection in the eluate of aspirated tissue were performed, and also routine postoperative pathological examination was performed. The results of PTH detection in the eluate of aspirated tissue and postoperative pathological examinations were compared and analyzed by SPSS and R software for e valuating of the sensitivity, specificity, positive predictive value, negative predictive value, misdiagnosis rate, missed diagnosis and accuracy. Results: Surgery was completed successfully in all patients. After surgery, the symptoms were improved in the patients except two who were asymptomatic. None had any serious postoperative complications such as hypocalcaemia or hoarseness. A total of 231 aspirated tissue samples were tested, of which 216 were identified as parathyroid and 15 non-parathyroid based on intraoperative PTH detection in tissue eluate; while 217 were confirmed as parathyroid tissues and 14 non-parathyroid tissues with postoperative pathological examinations. The specificity and sensitivity of intraoperative IFNA and PTH detection in tissue eluate for identifying parathyroid tissues were 99.5% and 100.0%, respectively. Conclusion: The IFNA and PTH detection in tissue eluate is a rapid, simple, and accurate procedure, which helps the surgeon to identi fy parathyroid tissue and to ensure the endocrine activity of preserved or autografted parathyroid tissue during parathyroidectomy.

xlomafota13 shared this article with you from Inoreader Detection of oropharyngeal sensory function in normal population Via Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi. 2021 Aug 7;56(8):830-836. doi: 10.3760/cma.j.cn115330-20200831-00713. ABSTRACT Objective: To study the oropharyngeal sensory function by Current Perception Threshold(CPT) detection, to explore the detection method of oropharyngeal sensory function in normal population, and to analyze the possible influencing factors. Methods: Fifty-eight normal subjects were included prospectively in this study. Age, gender, body mass index (BMI) were collected. The age of the subjects ranged from 20 to 76 (43.27±13.52) years old. There were 34 females with 17 in childbearing period and 17 in menopause; and 24 males were included.In all the cases, 6 cases were in low BMI, 39 cases were in normal BMI, 10 cases were overweight and 3 cases were suffering from obesity. The CPT system of Neurometer was used to stimulate bilateral palatoglossal arch and tongue base.The current used was 2000 Hz, 25 0 Hz and 5 Hz respectively.The function of type Aβ, Aδ and C sensory nerve fibers were tested and the CPT values were recorded.The values were inversely proportional to pharyngeal sensation function.To evaluate the oropharyngeal sensory function of the subjects, the CPT values of each frequency at each testing point were compared. SPSS 25.0 software was used for statistical analysis. Results: The CPT value of palatoglossal arch was significantly lower than that of tongue base (t=-2.58,-2.65,-2.54,-2.47,-2.37,-2.77,P<0.05), 2 000 Hz>250 Hz>5 Hz, and there was no significant difference between left and right sides(t=-0.03,-0.51,-0.49,0.06,-0.16,0.13,P>0.05). The CPT value of male was slightly higher than that of female (t=0.92,1.55,0.27,0.78,1.44,1.26,0.35,0.77,1.27,0.24,0.78,0.96,P>0.05). The CPT values of women in childbearing period were significantly less than those in menopausal women (t=-3.90,-3.64,-2.14,-4 .20,-4.28,-4.28,-3.52,-4.46,-3.41,-3.63,-4.66,-2.86,P<0.05). The CPT value increased with age, and the values of all frequency of 20 to 30 years old group was significantly lower than those of subjects over 40 years old at each point (The t values of bilateral palatoglossal arch at 2 000 Hz were -5.57,-6.22,-10.18,-11.00;the t values of bilateral palatoglossal arch at 250 Hz were -6.39,-8.79,-6.39,-15.61;the t values of bilateral palatoglossal arch at 5 Hz were -7.09, -5.57, -9.26, -15.23;the t values of tongue base at 2 000 Hz were -3.11,-3.88,-7.60,-8.55;the t values of tongue base at 250 Hz were -6.31,-10.59,-8.52,-10.60;the t values of tongue baseat 5 Hz were -6.69,-5.09,-8.70,-7.07,P<0.05).The values at all frequencies and testing points of 30-40 years old group were significantly lower than those of all subjects over 60 years old (The t values of bilateral palatoglossal arch at 2 000 Hz were -10.91,-12.42;the t values of bilateral palatoglossal arch at 250 Hz were -6.25,-10.87;the t values of bilateral palatoglossal arch at 5 Hz were -5.53,-11.01;the t values of tongue base at 2 000 Hz were -8.62,-10.12;the t values of tongue base at 250 Hz were -6.89,-7.82;the t values of tongue base at 5 Hz were -6.13,-6.48,P<0.05). Conclusions: CPT can be used to evaluate oropharyngeal sensory function. The sensitivity of tongue base is lower than that of palatoglossal arch, there is no significant difference in oropharyngeal sensory function between male and female,between left and right sides. There are many factors influencing oropharyngeal sensory function. Age, hormone level changes may affect the sensitivity of oropharyngeal sensory function.

Body mass index and type 2 diabetes and breast cancer survival: a Mendelian randomization study

xlomafota13 shared this article with you from Inoreader Body mass index and type 2 diabetes and breast cancer survival: a Mendelian randomization study Via American Journal of Cancer Research Am J Cancer Res. 2021 Aug 15;11(8):3921-3934. eCollection 2021. ABSTRACT The causal relationship between body mass index (BMI) and type 2 diabetes (T2D) and breast cancer prognosis is still ambiguous. The aim of this study was to investigate the prognostic effect of BMI and T2D on breast cancer disease-free survival (DFS) among Asian individuals. In this two-sample Mendelian randomization (MR) study, the instrumental variables (IVs) were identified using a genome-wide association study (GWAS) among 24,000 participants in the Taiwan Biobank. Importantly, the validity of these IVs was confirmed with a previous large-scale GWAS (Biobank Japan Project, BBJ). In this study, we found that a genetic predisposition toward higher BMI (as indicated by BMI IVs, F = 86.88) was associated with poor breast cancer DFS (hazard ratio [HR] = 6.11; P < 0.001). Furthermore, higher level of genetically predicted T2D (as indicated by T2D IVs) was associa ted with an increased risk of recurrence of and mortality from breast cancer (HR = 1.43; P < 0.001). Sensitivity analyses, including the weighted-median approach, MR-Egger regression, Radial regression and Mendelian randomization pleiotropy residual sum and outlier (MR-PRESSO) supported the consistency of our findings. Finally, the causal relationship between BMI and poor breast cancer prognosis was confirmed in a prospective cohort study. Our MR analyses demonstrated the causal relationship between the genetic prediction of elevated BMI and a greater risk of T2D with poor breast cancer prognosis. BMI and T2D have important clinical implications and may be used as prognostic indicators of breast cancer. PMID:34522458 | PMC :PMC8414374 View on the web Inoreader.

3'untranslated regions (3'UTR) of Gelsolin mRNA displays anticancer effects in non-small cell lung cancer (NSCLC) cells

xlomafota13 shared this article with you from Inoreader 3'untranslated regions (3'UTR) of Gelsolin mRNA displays anticancer effects in non-small cell lung cancer (NSCLC) cells Via American Journal of Cancer Research Am J Cancer Res. 2021 Aug 15;11(8):3857-3876. eCollection 2021. ABSTRACT RNA-based therapeutics has attracted substantial interest from both academics and pharmaceutical companies. In this study, we investigated the function and the underlying mechanism of Gelsolin (GSN) 3'UTR in NSCLC H1299 and A549 cells. We found that transfected Flag-GSN plasmids significantly increased the proliferation, migration and invasion of NSCLC cells, whereas GSN 3'UTR could suppress the promotional effect of GSN protein on the development of NSCLC in vitro. Interestingly, we observed that these in vitro anticancer effects of GSN 3'UTR was independent of the co-expression with GSN coding sequence. Moreover, transfected GSN 3'UTR affected the actin-cytoskeleton remodeling and epithelial-mesenchymal transition (EMT) processes in H1299 and A549 cells, and targeted the co-expressed proteins to the plasma membran e. Subsequently, RNA pull-down assays have been performed to identify Tra2β protein as a GSN 3'UTR binder. We then showed that Tra2β was important for the localized protein expression mediated by GSN 3'UTR. Taken together, our results suggested that GSN 3'UTR may exert anticancer functions in NSCLC cells through regulating the subcellular localized expression of GSN protein mediated by the interaction between GSN 3'UTR-Tra2β.

DNA damage in cancer development: special implications in viral oncogenesis

xlomafota13 shared this article with you from Inoreader DNA damage in cancer development: special implications in viral oncogenesis Via American Journal of Cancer Research Am J Cancer Res. 2021 Aug 15;11(8):3956-3979. eCollection 2021. ABSTRACT DNA lesions arise from a combination of physiological/metabolic sources and exogenous environmental influences. When left unrepaired, these alterations accumulate in the cells and can give rise to mutations that change the function of important proteins (i.e. tumor suppressors, oncoproteins), or cause chromosomal rearrangements (i.e. gene fusions) that also result in the deregulation of key cellular molecules. Progressive acquisition of such genetic changes promotes uncontrolled cell proliferation and evasion of cell death, and hence plays a key role in carcinogenesis. Another less-studied consequence of DNA damage accumulating in the host genome is the integration of oncogenic DNA viruses such as Human papillomavirus, Merkel cell polyomavirus, and Hepatitis B virus. This critical step of viral-induced carcinogenesis is thought to be particularly facilitated by DN A breaks in both viral and host genomes. Therefore, the impact of DNA damage on carcinogenesis is magnified in the case of such oncoviruses via the additional effect of increasing integration frequency. In this review, we briefly present the various endogenous and exogenous factors that cause different types of DNA damage. Next, we discuss the contribution of these lesions in cancer development. Finally, we examine the amplified effect of DNA damage in viral-induced oncogenesis and summarize the limited data existing in the literature related to DNA damage-induced viral integration. To conclude, additional research is needed to assess the DNA damage pathways involved in the transition from viral infection to cancer. Discovering that a certain DNA damaging agent increases the likelihood of viral integration will enable the development of prophylactic and therapeutic strategies designed specifically to prevent such integration, with an ultimate goal of reducing or eliminating these vi ral-induced malignancies.
