Objective: Iatrogenic vocal fold paralysis is an important issue in laryngology, yet there are few population-based studies regarding the epidemiology. This study used a nationwide population-based claims database (the National Health Insurance Research Database) to investigate the epidemiology of iatrogenic unilateral and bilateral vocal fold paralysis (UVFP/BVFP) among the general adult population in Taiwan. Method: This study analyzed patients (20-90 years old) who underwent thyroid, parathyroid, thoracic, cardiac, or anterior cervical spine operations with vocal fold paralysis among adults in Taiwan from January 1, 2007 to December 31, 2013. The codes for vocal fold paralysis were defined by International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Claims data in the Taiwan National Health Insurance Research Database were used. Results: The most commonly performed operations which were related to vocal fold paralysis in Taiwan were, in descending order of frequency, thyroid, cervical spine, cardiac, thoracic (esophagectomy), and parathyroid operations. The operations that put laryngeal nerves at risk (ONRs) most commonly associated with a diagnosis of UVFP were, in descending order of frequency, thoracic, thyroid, parathyroid, cardiac, and cervical spine. For both UVFP and BVFP, the most commonly associated age group was 51 to 60. For both UVFP and BVFP, the more commonly associated sex was women. Increased length of stay was associated with a higher incidence of UVFP and BVFP. Charlson medical co-morbidity index (CCI) was not associated with UVFP but BVFP was associated with higher Charlson medical co-morbidity scores. Conclusions: Thyroid operations, age 51 to 60, longer hospital stays are associated with vocal fold paralysis. Overall women are more surgically affected than men. This is the first population-based study of iatrogenic vocal fold paralysis.

Purpose: To evaluate the impact of parathyroid gland vasculature preservation in-situ technique (PGVPIST) on postoperative parathyroid hormone (PTH) and calcium plasma levels in thyroid patients undergoing total thyroidectomy for papillary thyroid carcinoma (PTC). Study Design: Retrospective cohort study. Methods: Patients with PTC who underwent total thyroidectomy by either the conventional technique (group 1, January 2019 to January 2020) or PGVPIST (group 2, January 2020 to January 2021) were compared. Postoperative blood calcium levels and PTH levels were assessed in these groups. Results: Totally 149 patients with consecutive PTC underwent total thyroidectomy, including 60 patients in group 1 and 89 patients in group 2. Postoperative serum calcium levels in group 1 were insignificantly lower than in group 2 at day 1 (2.18 ± 0.02 vs 2.15 ± 0.01 mmol/L) and day 30 (2.27 ± 0.02 vs 2.38 ± 0.11) after surgery. But postoperative serum PTH levels in group 1 were significantly lower than that in group 2 at day 1 (23.68 ± 2.54 vs 31.46 ± 2.11 pg/mL) and day 30 (45.63 ± 3.21 vs 55.65 ± 2.89 pg/mL) after surgery. Conclusion: Parathyroid gland vasculature preservation in-situ technique for PTC is associated with higher PTH level after total thyroidectomy. The parathyroid gland vasculature mostly strongly adheres with adjacent thyroid parenchyma. Therefore, deferred processing of tiny thyroid parenchyma of parathyroid gland vessels is essential to prevent devascularization.

Background: Growth retardation, malnutrition, and failure to thrive are some of the consequences associated with congenital heart diseases. Several metabolic factors such as hypoxia, anoxia, and several genetic factors are believed to alter the energetics of the heart. Timely diagnosis and patient management is one of the major challenges faced by the clinicians in understanding the disease and provide better treatment options. Metabolic profiling has shown to be potential diagnostic tool to understand the disease. Objective: The present experiment was designed as a single center observational pilot study to classify and create diagnostic metabolic signatures associated with the energetics of congenital heart disease in cyanotic and acyanotic groups. Methods: Metabolic sera profiles were obtained from 35 patients with cyanotic congenital heart disease (TOF) and 23 patients with acyanotic congenital heart disease (ASD and VSD) using high resolution 1D 1H NMR spectra. Univariate and multivariate statistical analysis were performed to classify particular metabolic disorders associated with cyanotic and acyanotic heart disease. Results: The results show dysregulations in several metabolites in cyanotic CHD patients versus acyanotic CHD patients. The discriminatory metabolites were further analyzed with area under receiver operating characteristic (AUROC) curve and identified four metabolic entities (i.e. mannose, hydroxyacetone, myoinositol, and creatinine) which could differentiate cyanotic CHDs from acyanotic CHDs with higher specificity. Conclusion: An untargeted metabolic approach proved to be helpful for the detection and distinction of disease-causing metabolites in cyanotic patients from acyanotic ones and can be useful for designing better and personalized treatment protocol.

Background: Transcatheter aortic valve replacement (TAVR) is associated with excellent results in patients with severe aortic stenosis. In highly calcified aortic anuli with increased risk of annulus rupture and in favor of the supra-annular design, self-expandable prostheses are frequently used. In this regard, we aimed to perform a comparative analysis of clinical and 30-day outcomes after TAVR using the self-expanding CoreValve® Evolut R or ACURATE neo™ prosthesis. Methods: Out of 343 consecutive patients treated with either CoreValve® Evolut R or ACURATE neo™ from January 2014 to December 2017, 76 patients were assigned each per group after 1:1 propensity score matching in regard of preoperative characteristics. Pre- and periprocedural outcomes were retrospectively collected and assessed. Outcomes at 30 days are reported according to the established Valve Academic Research Consortium (VARC-2) criteria. Results: Device success and 30-day survival accounted for 93.4% ( n = 71), respectively 97.4% ( n = 74) in both groups (p = 1.00). No statistically significant differences regarding clinical parameters were observed. The combined safety endpoint at 30 days was comparable (84.2% ( n = 64) CoreValve® vs 85.5% ( n = 65) ACURATE neo™; p = 0.848). Except a trend toward higher stroke (p = 0.08) and pacemaker (p = 0.07) rate in the CoreValve® group, major vascular complications, incidence of life-threatening or disabling bleeding, and incidence of postoperative acute kidney injury were comparable. Postoperative hemodynamic parameters showed no significant differences between the implanted valves. Conclusion: Both self-expandable prostheses showed good postoperative hemodynamic performance with a low incidence of severe paravalvular leakage, all- cause mortality, and comparable clinical outcomes.

We examined US parent and youth perceptions of how life events, both positive and negative, associated with COVID-19 resulted in changes in family and youth functioning. Families ( n = 105, 80% white, 48% male, and 87% mothers) completed surveys during the pandemic (May to July 2020) and 3 years prior (for youth ages M = 10.6, SD = 1.17 and M = 13.6, SD = 1.19). Declines in youth, though not parent, report of open family communication, parental support, and family satisfaction were found. Declines were associated with various domains of pandemic-related stress in parent report, though positive life events served as buffers. Pre-pandemic family functioning also predicted pandemic stress. Spillover effects in turn impacted youth functioning. The current findings shed light on how experiences of the pandemic are linked with family functioning and have implications for how to support families during this time.

Published: September 2021

Background: Autograft choice in anterior cruciate ligament reconstruction (ACLR) remains controversial, with increasing interest in the usage of quadriceps tendon (QT) autograft versus traditional hamstring tendon (HT) use. The current study undertakes an in-depth review and comparison of the clinical and functional outcomes of QT and HT autografts in ACLR. Hypothesis: The QT autograft is equivalent to the HT autograft and there will be little or no significant difference in the outcomes between these 2 autografts. Study Design: Systematic review and meta-analysis; Level of evidence, 4. Methods: The PUBMED, EMBASE, MEDLINE, and CENTRAL databases were systematically searched from their inception until November 2020. All observational studies comparing ACLR QT and HT autografts were assessed for their methodological quality. Patient outcomes were compared according to patient-reported outcome measures (International Knee Documentation Committee [IKDC], Cincinnati, Lysholm, Tegner, and visual analog scale [VAS] measures), knee extensor and flexor torque limb symmetry indices (LSIs), hamstring to quadriceps (H/Q) ratios, functional hop capacity, knee laxity, ipsilateral graft failure, and contralateral injury. Results: A total of 20 observational studies comprising 28,621 patients (QT = 2550; HT = 26,071) were included in the quantitative meta-analysis. In comparison with patients who received an HT autograft, those who received a QT autograft had similar postoperative Lysholm (mean difference [MD], 0.67; P = .630), IKDC (MD, 0.48; P = .480), VAS pain (MD, 0.04; P = .710), and Cincinnati (MD, -0.85; P = .660) scores; LSI for knee flexor strength (MD, 6.06; P = .120); H/Q ratio (MD, 3.22; P = .160); hop test LSI (MD, -1.62; P = .230); pivot-shift test grade 0 (odds ratio [OR], 0.80; P = .180); Lachman test grade 0 (OR, 2.38; P = .320), side-to-side laxity (MD, 0.09; P = .650); incidence of graft failure (OR, 1.07; P = .830) or contralateral knee injury (OR, 1.22; P = .610); and Tegner scores (MD, 0.11; P = .060). HT autografts were associated with a higher (better) side-to-side LSI for knee extensor strength (MD, -6.31; P = .0002). Conclusion: In this meta-analysis, the use of the QT autograft was equivalent to the HT autograft in ACLR, with comparable graft failure and clinical and functional outcomes observed. However, HT autografts were associated with better LSI knee extensor strength.

Introduction: The present study aimed to evaluate the feasibility and efficacy of CogmedRM, a computerized, home-based working memory (WM) training program, in children with NF1. Method: A pre-post design was used to evaluate changes in performance-based measures of attention and WM, and parent-completed ratings of executive functioning. Children meeting eligibility criteria completed CogmedRM over 9 weeks. Primary outcomes included compliance statistics and change in attention and WM scores. Results: Thirty-one children (52% male; M age = 10.97 ± 2.51), aged 8-15, were screened for participation; 27 children (87%) evidenced WM difficulties and participated in CogmedRM training. On average, participants completed 19.7 out of 25 prescribed sessions, with an adherence rate of 69%. Participants demonstrated improvements in short-term memory, attention, and executive functioning (all Ps < .05). Conclusion: Results suggest that computerized, home-based WM training programs may be both feasible and efficacious for children with NF1 and cognitive deficits.

Background Non-alcoholic steatohepatitis (NASH) is a global medical problem and macrophages’ activation is closely related to the pathogenesis of NASH. Curcumin is a polyphenol from turmeric with significant anti-inflammatory activity. Objective The objective of present study was to observe the effect of curcumin on macrophages’ activation and secretion of pro-inflammatory cytokines in NASH. Methods Hematoxylin and eosin and TUNEL staining were used to observe the hepatic function. RT-PCR was conducted to evaluate the hepatic mRNA expression of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β). Flow cytometry was adopted to detect the M1 polarization of macrophages. The RAW264.7 macrophage was pretreated with different doses of curcumin, and then lipopolysaccharide (LPS) and interferon-γ (IFN-γ) were given to activate the M1 macrophage. The activation ratio of M1 macrophage was observed by flow cytometry, and IL-1β and TNF-α expression was detected by RT-PCR and ELISA. Results After treatment with curcumin, the activities of alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the mRNA expression of TNF-α and IL-1β, and M1 polarization of macrophages were significantly decreased. Hematoxylin and eosin and TUNEL staining showed that inflammation and apoptosis in the liver were improved. What is more, curcumin can effectively inhibit M1 macrophage activation induced by lipopolysaccharide and IFN-γ and reduce the secretion of IL-1β and TNF-α. Conclusion Curcumin can effectively improve NASH and reduce hepatic cell necrosis by inhibiting the M1 polarization of macrophages and the secretion of inflammatory factors.

Objective Recent clinical trials confirmed the corticosteroid dexamethasone as an effective treatment for patients with COVID-19 requiring mechanical ventilation. However, limited attention has been given to potential adverse effects of corticosteroid therapy. The objective of this study was to determine the association between corticosteroid administration and impaired glycemic control among COVID-19 patients requiring mechanical ventilation and/or veno-venous extracorporeal membrane oxygenation. Design Multicenter retrospective cohort study between March 9 and May 17, 2020. The primary outcome was days spent with at least 1 episode of blood glucose either >180 mg/dL or <80 mg/dL within the first 28 days of admission. Setting Twelve hospitals in a United States health system. Patients Adults diagnosed with COVID-19 requiring invasive mechanical ventilation and/or veno-venous extracorporeal membrane oxygenation. Interventions None. Measurements and Main Results We included 292 mechanically ventilated patients. We fitted a quantile regression model to assess the association between steroid administration ≥320 mg methylprednisolone (equivalent to 60 mg dexamethasone) and impaired glycemic control. Sixty-six patients (22.6%) died within 28 days of intensive care unit admission. Seventy-one patients (24.3%) received a cumulative dose of least 320 mg methylprednisolone equivalents. After adjustment for gender, history of diabetes mellitus, chronic liver disease, sequential organ failure assessment score on intensive care unit day 1, and length of stay, administration of ≥320 mg methylprednisolone equivalent was associated with 4 additional days spent with glucose either <80 mg/dL or >180 mg/dL (B = 4.00, 95% CI = 2.15-5.85, P < .001). Conclusions In this cohort study of 292 mechanically ventilated COVID-19 patients, we found an association between corticosteroid administration and higher incidence of both hyperglycemia and hypoglycemia.

Published: September 2021

Purpose: To compare different intraocular pressure (IOP) readings in corneas with intrastromal corneal ring segments (ICRS) taken by three different tonometers; Goldmann applanation tonometry (GAT), air puff tonometer, and ocular response analyzer (ORA) corneal-compensated IOP (ORA-IOPcc) and determine the relation of these measurements to different corneal parameters taken by Pentacam. Methods: An observational cross-sectional analytic study included patients who underwent ICRS keraring implantation at 3 months. In each eye, the two rings were placed using the femtosecond laser assisted technique 5.5 or 6 mm from the center. IOP was measured using three different tonometers; GAT, air puff tonometer, and ocular response analyzer (ORA) corneal-compensated IOP (ORA-IOPcc). Results: Fifty eyes of 30 patients (20 males and 10 females) aged 27.56 ± 6.38 years were included. IOP measurements by GAT, air puff tonometer, and ORA-IOPcc were 13.28 ± 2.13 mmHg, 10.47 ± 2.55 mmHg, and 13.19 ± 2.78 mmHg, respectively. Comparisons between air puff and each of GAT and ORA-IOPcc were statistically highly significant ( p-value <0.001). Conclusion: IOP measurements taken by air puff tonometer were significantly lower than those taken by GAT and ORA-IOPcc. These differences were not constant across the pressure range but increased as the pressure values determined using GAT and ORA increased. ORA-IOPcc and GAT showed similar readings. No correlation was found between any of the IOP readings taken by the three tonometers and the central corneal thickness.

Authors: Clesham Jennifer , Reynolds Helen , Carr Peter J 
Published: September 2021

Introduction: The extent of vascular/venous access device (VAD) research output from the Island of Ireland is unknown. The identification of the papers available is important to create a future research agenda. Objectives: The main objective of this study is to answer three questions: What is the number and descriptive quality of reported Vascular Access Device literature from the Island of Ireland? Is the reporting of Catheter Related Infection rates for cancer patients common in Irish Hospital Groups, National Cancer Reports and Publication Outputs? What are the implications for future research in this area? Methods: We used a scoping review and searched selected databases, grey literature and hospital regulatory bodies websites following the Joanna Briggs Institute Guidelines 2017. A data charting form was developed based on a template from the Joanna Briggs Institute and this was used to extract data from the included reports. Results: A total of 660 reports were screened. Sixty-one full text articles were reviewed from which 20 reports were included for data extraction. Of the reports included the following designs were used: nine retrospective study designs, four guidelines, two prospective study designs, two literature reviews and one of the following; survey, case study and cross sectional analysis designs. We did not identify any randomised controlled trials, systematic reviews, meta-analysis, meta-synthesis and scoping reviews. Five studies included catheter related infection rates. Gaps in the research include the collection of data sets and the need to establish a VAD registry; develop core outcomes for VADs; assessment and evaluation of VAD care bundles among cancer patients; and, the inclusion of public and patient involvement in future VAD research. Conclusion: The reporting of VAD outcomes in published literature regarding cancer patients receiving treatment in Ireland is inconsistent and varied with no interventional studies addressing vascular access complications in cancer care.

HSV-1 is associated with oral lesions. Recently, anti-herpetic activity of different plant species has been investigated. In this study, the effects of Artemisia aucheri aqueous extract on the HSV-1 virus-infected Vero cells were assessed. The highest cell viability occurred in plant aqueous extracts was with a concentration of 75 μg/mL, 1–2 h before viral infection. The IC50 of the aqueous extract of 24.7 μg/ml was calculated. Most percentage of infected cell inhibition (89.6%) was with the chloroform fraction in concentration of 75 μg/ml, and the least percentage of infected cell inhibition (21.7%) was in concentration of 12.5 μg/ml with the ethyl acetate fraction in comparison with untreated control. Moreover, Q-PCR results revealed that the expression of genes UL46 and US6 were significantly reduced in the presence of different treatments utilized in the experiment. In conclusion, the present study proposes that aqueous extracts of medicinal plant Artemisia aucheri have anti-viral property and may be considered as a remedy for HSV-1 treatment.

We aimed to assess the influence of fracture location and comminution on acute scaphoid fracture displacement using three-dimensional CT. CT scans of 51 adults with an acute scaphoid fracture were included. Three-dimensional CT was used to assess fracture location, comminution and displacement. Fracture location was expressed as the height of the cortical breach on the volar and dorsal side of the scaphoid relative to total scaphoid length (%), corresponding to the fracture’s entry and exit point, respectively. We found a near-linear relation between dorsal fracture location and displacement. As dorsal fracture location became more distal, translation (ulnar, proximal, volar) and angulation (flexion, pronation) of the distal fragment relative to the proximal fragment increased. Comminuted fractures had more displacement. Dorsal fracture location predictably dictates the direction of translation and angulation in displaced scaphoid fractures. Surgeon attention to dorsal fracture location can help identify displacement patterns and provide guidance in adequately reducing a displaced scaphoid fracture. Level of evidence: III
