Authors: Brake Daniela A. , Patel Rita R. , Risser Rebecca M. , Ambrose Gabrielle , Anthony Benjamin P. 
Published: September 2022

Objective: To compare voice-related outcomes of type 1 thyroplasty using Gore-Tex® between patients with and without augmentation injection laryngoplasty (IL) prior to surgery. Methods: Forty-five patients who underwent Gore-Tex® thyroplasty at a single institution by a single surgeon between November 2016 and February 2019 were identified as those who previously had IL (n = 20) and those without IL (n = 25). Pre- and post-operative voice-related primary outcomes were evaluated using the GRBAS, and CAPE-V auditory-perceptual rating scales and secondary outcome were evaluated using the VRQOL. Pre- and post-operative voice samples were blinded, randomized, and analyzed by 3 voice-specialized speech pathologists to obtain CAPE-V scores. The VRQOL and GRBAS scores were obtained from retrospective chart review. Student’s t test with a paired one-tailed distribution was used for comparisons within groups and 2-sample equal variance for comparisons between groups. Intraclass correlation coefficient determined interrater agreement. Results: GRBAS, and VRQOL significantly improved post Gore-Tex® thyroplasty. There was no difference in improvement between patients who received pre-surgery IL and those who did not in either GRBAS or VRQOL scores, but CAPE-V showed significant improvement in the IL group. A strongly positive correlation was demonstrated between the severity of CAPE-V pre-op score and the overall improvement following surgery for both groups combined. Conclusion: Patients with vocal fold paralysis have a significantly better voice after Gore-Tex® thyroplasty by self-report (VRQOL) and assessment by trained voice professionals (GRBAS). Having IL prior to surgery does not adversely affect later surgical outcomes. This paper represents one of the largest analyses of voice quality outcomes of Gore-Tex® thyroplasty using validated patient scales and randomized blinded analyses.

Background: Fortification of rice with slaked lime is an acceptable and inexpensive way to combat calcium (Ca) deficiency. However, bioavailability of calcium after intake of slaked lime fortified rice is yet to be investigated. Objective: To measure the fractional absorption of Ca (FAC) from slaked lime fortified cooked rice. Design: We conducted an experimental study using stable isotopes of Ca to measure FAC during a single morning test meal containing rice fortified with slaked lime. Participants (n = 22) were given slaked lime fortified rice 3 times a day for 4 days. On the morning of the fifth day, the participants were served the same amount of rice as previous the 4 days at the breakfast test meal with an accurately measured amount of 44Ca stable isotope oral tracer followed by an intravenous injection of 42Ca. Urine was collected over the next 24 hours in 3 consecutive 8-hour pools. Fractional absorption of Ca was calculated from the measurement of the relative enrichment of the of each administered tracer 44Ca and 42Ca using inductively coupled plasma mass spectrometry. Results: The mean Ca concentration in the test meal was 879.5 ± 152.9 µg/g with a coefficient of variance (CV) of 17.2%. Although Ca absorption efficiency decreases with higher calcium intake, the total amount of calcium absorbed from test meal using FAC = 0.391 calculated from the third 8-hour urine pool was 69.0 (CV of 15.6) mg. Conclusions: We showed that one-fifth of daily calcium recommendation for women of reproductive age could be met by ingesting ∼200 g cooked slake fortified rice.

Published: September 2022

Background: Agroecological methods have the potential to impact nutrition and food security, however, to date there is limited research evaluating this approach. Objective: A 5-year participatory research project with farming households in north and central Malawi was designed to train farmers on agroecological practices, alongside raising awareness on nutrition and gender equity. This cross-sectional study aimed to explore the relationships between crop diversity, food security at the household level, and individual diversity for women, within the context of an agroecology, nutrition education, and farmer mentoring program. Methods: Participating farmers were trained in and experimented with different farming methods. These farmers subsequently trained other farmers on these short-term agroecological practices and provided mentorship using community-based educational methods designed to address both household food security and nutrition. In year 4 of the intervention, a cross-sectional survey assessed farm practices, food security, and individual dietary diversity of 851 participating households. Results: Households with lower crop diversity were significantly less likely to be food secure (odds ratios [OR] = 0.829, P < .001). Women in households with higher crop diversity were more likely to have higher individual dietary diversity (OR = 1.120, P < .01), eat vitamin A rich foods (OR = 1.176, P < .01), and legumes, nuts, and seeds (OR = 1.141, P < .01). Conclusions: These findings suggest that within a participatory agroecological training combined with community-based nutrition education with a focus on social equity, crop diversity is associated with less household food insecurity and poorer diet quality for rural farming households. Crop diversity may improve dietary diversity by making nutritious foods more available.

Background Invasive ductal carcinoma (IDC) is the most common type of breast cancer so its early detection can lead to a significant decrease in mortality rate. However, prognostic factors for IDC are not adequate and we need novel markers for the treatment of different individuals. Although positron emission tomography and magnetic resonance imaging techniques are available, they are based on morphological features that do not provide any clue for molecular events accompanying cancer progression. In recent years, “omics” approaches have been extensively developed to propose novel molecular signatures of cancers as putative biomarkers, especially in biofluids. Therefore, a mass spectrometry-based metabolomics investigation was performed to find some putative metabolite markers of IDC and potential metabolites with prognostic value related to the estrogen receptor, progesterone receptor, lymphovascular invasion, and human epidermal growth factor receptor 2. Methods An untargeted metabolomics study of IDC patients was performed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The multivariate principal component analysis by XCMS online built a model that could separate the study groups and define the significantly altered m/z parameters. The most important biological pathways were also identified by pathway enrichment analysis. Results The results showed that the significantly altered metabolites in IDC serum samples mostly belonged to amino acids and lipids. The most important involved pathways included arginine and proline metabolism, glycerophospholipid metabolism, and phenylalanine, tyrosine, and tryptophan biosynthesis. Conclusions Significantly altered metabolites in IDC serum samples compared to healthy controls could lead to the development of metabolite-based potential biomarkers after confirmation with other methods and in large cohorts.

Published: September 2022

Purpose This review evaluated the knowledge, utilisation, prevention education, and policy response across the six geopolitical regions of Nigeria to inform national efforts for the prevention and control of cervical cancer. Methods A keyword-based systematic search was conducted in PubMed/MEDLINE (NCBI), Google Scholar, and AJOL electronic databases, including a manual scan of papers, journals and websites to identify relevant peer-reviewed studies. Articles were screened and assessed for eligibility. Results Many (158) articles were downloaded and after duplicates were removed, 110 articles were included in the final analysis. These were made up of qualitative, quantitative (cross-sectional), intervention and policy studies. Studies have generally reported poor knowledge and awareness of cervical cancer screening but those carried out in urban areas demonstrated a slightly higher level of awareness of Human Papilloma Virus (HPV) vaccine, HPV vaccination uptake and utilization of cervical cancer preventive services than the rural studies. The studies did not show strong government support or policies in relation to cervical cancer control. Conclusion Knowledge and uptake of cervical cancer preventive services across diverse groups in Nigeria remain poor. These could be linked to socio-cultural factors, the lack of an organised cervical cancer screening programme and low financial resource pool for cervical cancer prevention. Therefore, it is necessary to increase government, donor prioritisation and political support in order to ensure increased investment and commitment to cervical cancer elimination in Nigeria.

Published: September 2022

Introduction: Multi-omics data integration facilitates collecting richer understanding and perceptions than separate omics data. Various promising integrative approaches have been utilized to analyze multi-omics data for biomedical applications, including disease prediction and disease subtypes, biomarker prediction, and others. Methods: In this paper, we introduce a multi-omics data integration method that is constructed using the combination of gene similarity network (GSN) based on uniform manifold approximation and projection (UMAP) and convolutional neural networks (CNNs). The method utilizes UMAP to embed gene expression, DNA methylation, and copy number alteration (CNA) to a lower dimension creating two-dimensional RGB images. Gene expression is used as a reference to construct the GSN and then integrate other omics data with the gene expression for better prediction. We used CNNs to predict the Gleason score levels of prostate cancer patients and the tumor stage in breast cancer patients. Results: The model proposed near perfection with accuracy above 99% with all other performance measurements at the same level. The proposed model outperformed the state-of-art iSOM-GSN model that constructs the GSN map based on the self-organizing map. Conclusion: The results show that UMAP as an embedding technique can better integrate multi-omics maps into the prediction model than SOM. The proposed model can also be applied to build a multi-omics prediction model for other types of cancer.

Objective Carotid endarterectomy is associated with fewer procedure-related strokes than transfemoral carotid artery stenting in older populations, based on the results from previous quality randomized controlled studies. Transcarotid artery revascularization (TCAR) is a hybrid procedure completed in the setting of cerebral flow reversal to deploy a stent, making it an appealing choice for older patients. This study was completed to elicit any age-related differences in outcomes after undergoing TCAR in patients 70 years of age and older. Methods A retrospective review was completed of a dual institutional database between December 2015 and April 2022 to capture demographics, comorbidities, and perioperative results. The geriatric cohort was defined at a cutoff of 70 years. Univariate statistical testing between groups were completed with Student’s T-test or Fisher’s exact test at an α of .05 for continuous and categorical variables, respectively. Results 851 procedures were captured for statistical analysis. With age cutoff of 70 years, we generated 567 geriatric (78.4 ± 5.7 years) and 284 young (63.2 ± 5.7 years) patients. The older patients tended to have more baseline illness, as measured by a higher rate Charlson Comorbidity Index (4.4 ± 2.2 vs 6.0 ± 2.1, P < .01). Younger patients tended to be actively smoking (42.3% vs 17.6%, P < .01). Intraoperative variables were grossly similar by age, including blood loss (43.0 ± 45.0 vs 45.7 ± 50.3 mLs, P = .45), reverse flow time (9.0 ± 7.4 vs 9.0 ± 6.7 mins, P = .98), and technical success (98.9% vs 98.6%, P = .76). While we observed an increased rate of stroke in the older patients, this did not reach statistical significance (1.4% vs 2.6%, P = .33). There were no differences between age groups with respect to myocardial infarction (0% vs .5%, P = .55) and death (1.1% vs 1.1%, P > .99) in the 30-day perioperative period. Conclusion We found that TCAR was not associated with age-related increases in adverse outcomes and can be considered a viable option when treating carotid artery stenosis in patients older than 70 years of age.

Published: September 2022

Background: Brachial plexus reconstruction (BPR) is a rapidly advancing field within hand surgery. BPR procedures are complex, time-intensive, and require microsurgical expertise. As physician reimbursement rates for BPR are poorly defined, relative to more common hand procedures, we sought to analyze compensation for BPR across different payor groups and understand the factors contributing to their reimbursement. Methods: A retrospective review was performed of surgeries by a single senior staff member in a 4-year period to evaluate Current Procedural Terminology (CPT) codes from BPR cases. For comparison, all finger fracture fixations and skin graft reconstructions performed by the same surgeon over the same time period were analyzed as well. Results: A total of 57 BPR cases, 94 finger fracture fixation cases, and 69 skin grafting cases met inclusion criteria. Among the top 5 insurance providers, average work relative value unit (wRVU)/hour was 6.55, 3.49, and 12.67 for BPR, fracture fixation, and skin grafts, respectively. Reimbursements were an average $685.76/hour for BPR, compared to $590.10/hour for fracture fixation and $1,197.94/hour for skin grafts. Conclusions: BPR demonstrates a relative undervaluation, in terms of reimbursement per hour, given the time and surgical skill required for such cases, particularly compared to shorter, less complex cases such as skin grafting and fracture fixation. We find that this discrepancy is amplified across multiple levels of coding, billing, and reimbursement. We suggest specific strategies for physician leadership to more directly participate in the financial decisions that affect themselves, their patients, and their specialty.

Published: September 2022

Background: Osteoarthritis of the hand can lead to pain, stiffness, and deformation, and thus to functional disability. The purpose of this study was to compare short-term clinical outcomes of 2 silicone proximal interphalangeal (PIP) joint implants, NeuFlex and Integra, in patients with primary osteoarthritis. Methods: We included 72 PIP joints, of which 40 were replaced by a NeuFlex implant and 32 by an Integra implant. The average follow-up was 12 months for the Integra group and 16 months for the NeuFlex group. Results: There was no change in active flexion preoperatively and postoperatively. Extension lag and Disabilities of the Arm, Shoulder, and Hand score decreased substantially in both groups, whereas grip strength and Patient-Specific Functional Scale (PSFS) score increased. All patients were satisfied. Between groups, there was a significant difference in the PSFS score, in favor of the Integra group. Conclusions: Both implants have excellent results, but more research is needed with more patients to prevent bias and to determine the long-term outcome of these implants.

Published: September 2022

Background The use of balloon microcatheters in interventional neuroradiology is well documented. However, their use is sometimes limited by the small diameter and excessive tortuosity of the vasculature. The Scepter Mini dual-lumen balloon microcatheter (SMBM) (Microvention, Aliso Viejo, CA) has been designed to address these challenges by decreasing the distal catheter profile, allowing distal access to the target vessel. Methods This is a single-centre retrospective analysis of the initial cases performed using the Scepter Mini balloon microcatheter. The targeted conditions were vascular malformations. Patient clinical data, angiographic features of the vascular abnormalities and operation reports were reviewed and the procedural parameters, radiation doses, occlusion rates and complications were assessed. Results A total of 15 SMBM were used in 11 cases. In all cases the procedure performed was balloon inflation and antegrade delivery of precipitating hydrophobic injectable liquid (PHIL) (Microvention, Aliso Viejo, CA) for embolisation of a targeted feeding vessel and cranial and spinal vascular malformations. Successful feeding vessel distal access and antegrade liquid embolisation was achieved in 100% of the cases. One of the 11 cases was an emergency procedure. One procedural target vessel rupture, likely due to overinflation, and three minor post-procedure complications were observed. Conclusion The SMBM represents a significant advance in the treatment of cerebrospinal vascular malformations, allowing balloon catheter access into tortuous and small calibre vessels.

Authors: Koch Lydia , Csebi Peter , Lipnik Karoline , Gradner Gabriele 
Published: September 2022

Case summary A 2-year-old cat was presented with nasopharyngeal stridor and stertor. Radiographs of the upper neck region showed a mass lesion in the nasopharynx. A nasopharyngeal polyp was suspected, but an attempt at endoscopic removal failed, owing to fragmentation of the mass and excessive haemorrhage. A sample was taken and histology confirmed a dermoid cyst. CT was performed and the lesion was described as most likely to be a dermoid cyst, consistent with the histopathological findings. Surgical exploration and subsequent complete removal of the mass led to a full recovery. Relevance and novel information The nasopharyngeal location represents a previously unreported location of a dermoid cyst. This report raises awareness of dermoid cysts as a potential differential diagnosis within the nasopharyngeal region and highlights the importance of pre-interventional diagnostic imaging.

Published: September 2022

Background: Femoroacetabular impingement (FAI) is primarily caused by bony impingement between the acetabulum and femoral neck during hip motion. Increasing posterior pelvic tilt improves hip range of motion in patients with FAI. Purpose: To use computer simulation analysis to compare the effects of 3-dimensional (3D) changes in pelvic tilt (sagittal tilt [St], axial rotation, and coronal tilt) with changes in a single plane (St), with the aim of improving range of motion in patients with FAI. Study Design: Controlled laboratory study. Methods: We evaluated 43 patients with FAI treated by arthroscopic cam resection. A 3D simulation was used to construct the following pelvic models: a 5° and 10° increase posteriorly in St (St5° and St10°) and a combined 5° change in St, axial rotation, and coronal tilt (Complex5°) from the baseline of the anterior pelvic plane. Improvements in maximum internal rotation (MIR) at 45°, 70°, and 90° of hip flexion and improvements in maximum flexion with no internal rotation were compared among the St5°, St10°, and Complex5° models. The pelvic models of each single-plane change of 5° and 10° were evaluated in the same simulation. Results: At 90° and 70°, there was a significant difference between the Complex5° and St10° models with respect to improvement in MIR ( P = .004 at 90° of flexion; P = .017 at 70° of flexion). There was no significant difference in MIR at 45° of flexion ( P = .71) or in maximum flexion ( P = .42). Conclusion: At 70° and 90° of hip flexion, a combined change in 3D pelvic alignment of 5° (ie, St, axial rotation, and coronal tilt) was more effective in improving hip MIR than a 10° change in St only. Clinical Relevance: Effective physical therapy for FAI should address pelvic motion in all 3 planes rather than in a single plane.
