Outcomes of Autologous Osteochondral Transplantation With and Without Extracellular Matrix Cartilage Allograft Augmentation for Osteochondral Lesions of the Talus
Authors: Mercer Nathaniel P. , Samsonov Alan P. , Dankert John F. , Kennedy John G. 
Published: November 2021

Background: Autologous osteochondral transplantation (AOT) using a cylindrical graft in the treatment of osteochondral lesions of the talus (OLTs) is typically indicated for patients with larger lesions. However, with lesions that are irregular in shape, the AOT graft may not completely replace the lesion. For these lesions, we utilize extracellular matrix cartilage allograft (EMCA) augmentation in AOT to act as a physiologic grout at the host-graft interface. Purpose: To determine if the combination of EMCA with concentrated bone marrow aspirate (CBMA) would improve integration of the host-graft interface and subsequently reduce postoperative cyst formation after AOT. It was also hypothesized that EMCA in conjunction with CBMA would demonstrate improved MOCART (magnetic resonance observation of cartilage repair tissue) scores and functional outcome scores at a minimum 2 years after surgery. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective analysis was performed comparing patients treated with AOT/CBMA alone and AOT with CBMA/EMCA. Clinical outcomes were evaluated with the Foot and Ankle Outcome Score. Magnetic resonance imaging appearance was evaluated with the use of the MOCART (magnetic resonance observation of cartilage repair tissue) score. Cyst formation was also evaluated on postoperative magnetic resonance imaging. Results: A total of 26 patients were included in the AOT + CBMA/EMCA group (10 male, 16 female), and 34 patients were included in the AOT/CBMA group (17 male, 17 female). The mean Foot and Ankle Outcome Score significantly improved in both groups ( P < .001) across all subscales (symptoms, pain, activities of daily living, sports activities, and quality of life), but there was no significant difference between groups at final follow-up. There was no significant difference in mean MOCART scores between the groups ( P = .118). In the AOT/CBMA group, 3 patients (8.8%) complained of knee pain, and 1 (2.9%) required additional surgery (hardware removal). In the AOT + CBMA/EMCA group, 2 patients (7.7%) complained of knee pain, and 6 patients (23%) required additional surgery (3 hardware removals and 3 arthroscopic debridements of scar tissue in the ankle). Conclusion: We found that while EMCA with CBMA has benefit in regeneration and repair of OLT treated with bone marrow stimulation, there appears to be little benefit of EMCA over CBMA alone as a physiologic grout at the graft-host interface in OLT treated with AOT.
Subcutaneous Dihydrocodeine Tartrate: Compatibility in a Syringe Pump With Other Drugs Frequently Prescribed for the Management of Symptoms Associated With Brain Tumors
Authors: Isherwood Ruth , Forsyth Amy , Wilson Anne 
Published: November 2021

Background Dihydrocodeine can be more effective in the management of headache due to brain tumor than other opioids. It can be used as a subcutaneous infusion, but at present, there is little available data to support its use in combination with other medicines in a syringe pump. Aim This project aimed to establish physical stability data for the use of dihydrocodeine with other drugs when combined in a syringe pump. Design: Dihydrocodeine was combined in a syringe pump with either cyclizine, midazolam, or hyoscine butylbromide at different doses chosen to represent routine clinical practice. Each drug combination was repeated twice—with 0.9% sodium chloride and with water for injections. Setting: The project was conducted in an independent hospice after seeking appropriate approvals to use the drugs for this purpose. Results Dihydrocodeine and midazolam appear compatible at when 0.9% sodium chloride is used as the diluent. Dihydrocodeine and cyclizine appeared compatible when either 0.9% saline or water for injections was used as the diluent. Dihydrocodeine and hyoscine butylbromide appeared compatible with either diluent at 24 hours. Conclusions Physical stability data has been described that will support the use of dihydrocodeine and other drugs that are commonly used to manage symptoms due to brain tumors at the end of life. This information will benefit patients and ensure that one syringe pump can be used where possible. Future work could expand on this data and explore the physical stability of three drug combinations in each syringe.

Idarubicin (IDA) is an anthracycline antibiotic, frequently used for the treatment of various human cancers. In vivo rodent model studies have identified a variety of possible adverse outcomes from IDA including heart effects like increased heart weights, myocardial histopathological injury, electrocardiogram abnormalities, and cardiac dysfunction. Despite significant investigations, the molecular mechanisms responsible for the cardiotoxicity of IDA have not been fully clarified. The aim of the current study was to investigate the effects of IDA on the HL-1 cardiac muscle cell. Different concentrations of IDA (10−6, 10−5, 10−4, and 10−3 M) were used at different time (6, 12, 24, and 48 h) periods, and the Cell Counting Kit-8 (CCK-8); 2,7-dichlorodihydrofluorescein diacetate (DCFH-DA) probe method; and enzyme-linked immunosorbent assay (ELISA) were used to detect the oxidative stress level. In addition, we used network analysis to predict IDA-induced cardiotoxicity. The TUNEL assay, qRT-PCR, ELISA assay, and Western blotting detection of related apoptotic factors including caspase family, Bax, and Bcl-2. Overall, we found that IDA was generally more toxic at high concentrations or extended durations of exposure. At the same time, IDA can increase the content of reactive oxygen species (ROS), malondialdehyde (MDA), and decrease the level of superoxide dismutase (SOD), catalase (CAT), and glutathione (GSH) in cells, and increase the content of lactate dehydrogenase (LDH) and nitric oxide synthase (NOS) in the medium. Network analysis showed that the apoptosis signaling pathway was activated; specifically, the caspase family was involved in the signal pathway. The results of the TUNEL assay, qRT-PCR, ELISA, and Western blot found that IDA can activate apoptotic factors. The mechanism may be related to the activation of apoptosis signaling pathway. These results indicate that the cardiotoxic effects of IDA are most likely associated with oxidative stress and ROS formation, which finally ends in apoptotic factors’ activation and induction of cell apoptosis.

Objective To determine differences in burden of care between nonsyndromic patients with unilateral cleft lip and palate undergoing treatment at American Cleft Palate-Craniofacial Association (ACPA)-accredited centers and nonaccredited centers in New York State. Design A retrospective review of the New York Statewide Planning and Research Cooperative System database from January 2001 to December 2014 was performed using ICD-9 and CPT coding. Patients, participants This study included patients with unilateral cleft lip and palate who underwent both lip and palate repairs during their first  6 years of life. Exclusion criteria included orofacial cleft syndromes, follow-up under  6 years, and one-stage combined cleft lip and palate repairs. Results Eighty-eight patients were treated at cleft centers, and 29 patients at nonaccredited centers (   n = 117). Age at primary palatoplasty (13.0 months vs 18.1 months;    p = .019), total number of cleft operations (2.3 vs 2.7;    p = .012), and total number of primary cleft-specific procedures (2.2 vs 2.5;    p = .0049) were significantly lower for patients treated in cleft centers. Age at primary cheiloplasty (4.8 months vs 4.6 months;    p = .865), post-cheiloplasty length of stay (1.2 days vs 1.2 days;    p = .673), post-palatoplasty length of stay (1.5 days vs 1.9 days;    p = .211), average hospital admissions (2.2 vs 2.3; p = 0.161), and total complication rates (34.1% vs 21.1%; p = 0.517) did not differ significantly between cleft centers and noncenters. Conclusions This data demonstrates some significant differences in overall 6 year burden of care for nonsyndromic patients with unilateral cleft lip and palate treated at ACPA-accredited cleft centers versus nonaccredited centers.

Introduction Robin sequence (RS) is a leading cause of obstructive sleep apnea (OSA) in newborns. Most studies have focused on understanding anatomic factors leading to OSA and changes in apnea–hypopnea index (AHI) on polysomnography (PSG) beyond the neonatal period. This study aims to define age-related OSA features between patients with RS, without RS and healthy controls using PSG-based analyses of respiratory arousal responses and gas-exchange parameters. Design Retrospective comparison of PSG features in a total of 48 children encompassing three groups: (a) infants with RS (n = 24, <1-year old), (b) non-RS older children (1-2 years old) with severe OSA (obstructive AHI (OAHI) of ≥10 events; n = 12), and (c) control infants and children (0-2 years old) without sleep apnea (OAHI ≤1.5/h, n = 12). We examined OSA sleep-stage specific and position-specific indexes, and the relationship between OSA severity and respiratory arousal indexes (OAHI/respiratory arousal indexes). Results OSA sleep-stage specific indexes (rapid eye movement [REM] vs non-REM[NREM]) as well as position-specific indexes (supine vs nonsupine) were similar in individuals with and without RS. Relative to the non-RS groups, infants with RS have more sustained hypoxemia (time with SpO2 < 90%) and reduced arousal responses to OSA demonstrated by higher OAHI/respiratory arousal indexes. OAHI/respiratory arousal indexes significantly correlated with the severity of hypoxemia in infants with RS. Conclusion Infants with RS and OSA show reduced arousal responses to apneic events, which correlates with higher hypoxemia severity. OAHI/respiratory arousal indexes in RS may identify high-risk individuals with upper airway obstruction and reduced arousal protective responses.

Published: November 2021

To analyse the morphological presentation of orofacial clefts, gender, syndromes and systemic anomalies associated with them. This was an epidemiological study performed in the patients who were registered for cleft lip and palate surgeries in our centre. The data was evaluated both retrospectively as well as prospectively. The patients registered from November 2006 to April 2021 were studied. Out of 5276 patients, data of 5004 cases were analysed, rest 272 patients were excluded due to lack of information. Statistical analysis and Chi square test were applied. Cleft deformities were more common in males than females. Cleft lip with palate was the commonest phenotype (52.2%). It was followed by isolated cleft lip (22.9%), isolated cleft palate (22.1%), rare clefts (1.62%) and syndromic clefts (1.18%). Unilateral variants were more frequent than bilateral. In unilateral, left side was more common than the right side. Among bilateral, most of the cases had premaxillary protrusion. In the present study, 3.46% of all the patients had associated anomalies affecting their other organs. Less common cleft phenotypes like microform cleft lip and submucous cleft palate ± bifid uvula showed frequency of 0.62% and 0.64% respectively. Thorough examination of cleft deformity should be done as it may appear as an isolated deformity or part of a syndrome and have associated systemic anomalies. This may help us to deliver comprehensive care to the patients and can prevent potential operative complications.

Published: November 2021

Objective A qualitative sub-study was carried out within a larger phase II feasibility trial, to identify and describe the burden experienced by advanced melanoma patients participating in a clinical trial and the factors affecting their capacity to cope with the burden. Methods Semi-structured interviews were conducted with fourteen patients with advanced melanoma recruited from National Health Service hospitals in the United Kingdom. Qualitative analysis was undertaken using a framework analysis approach. Normalisation process theory was applied to the concept of research participation burden in order to interpret and categorise findings. Results Burdens of participation were identified as arising from making sense of the trial and treatment; arranging transport, appointment and prescriptions; enacting management strategies and enduring side effects; reflecting on trial documents and treatment efficacy, and emotional and mental effects of randomisation and treatment side effects. Factors reported as influencing capacity include personal attributes and skills, physical and cognitive abilities and support network. Discussion This is the first study to highlight the substantial burden faced by patients with advanced melanoma in a clinical trial and factors that may lessen or worsen the burden. Consideration of identified burdens during trial design and execution will reduce the burden experienced by research participants.

Abstract
Background
The KidneyIntelX™ test applies a machine learning algorithm that incorporates plasma biomarkers and clinical variables to produce a composite risk score to predict a progressive decline in kidney function in patients with type 2 diabetes (T2D) and early-stage chronic kidney disease (CKD). The following studies describe the analytical validation of the KidneyIntelX assay including impact of observed methodologic variability on the composite risk score.

Methods
Analytical performance studies of sensitivity, precision, and linearity were performed on three biomarkers assayed in multiplexed format: kidney injury molecule-1 (KIM-1), soluble tumor necrosis factor receptor-1 (sTNFR-1) and soluble tumor necrosis factor receptor-2 (sTNFR-2) based on Clinical Laboratory Standards Institute (CLSI) guidelines. Analytical variability across twenty (20) experiments across multiple days, operators, and reagent lots was assessed to examine the impact on the reproducibility of the composite risk score. Analysis of cross-reactivity and interfering substances was also performed.

Results
Assays for KIM-1, sTNFR-1 and sTNFR-2 demonstrated acceptable sensitivity. Mean within-laboratory imprecision coefficient of variation (CV) was established as less than 9% across all assays in a multi-lot study. The linear range of the assays was determined as 12–5807 pg/mL, 969–23,806 pg/mL and 4256–68,087 pg/mL for KIM-1, sTNFR-1 and sTNFR-2, respectively. The average risk score CV% was less than 5%, with 98% concordance observed for assignment of risk categories. Cross-reactivity between critical assay components in a multiplexed format did not exceed 1.1%.

Conclusions
The set of analytical validation studies demonstrated robust analytical performance across all three biomarkers contributing to the KidneyIntelX risk score, meeting or exceeding specifications established during characterization studies. Notably, reproducibility of the composite risk score demonstrated that expected analytical laboratory variation did not impact the assigned risk category, and therefore, the clinical validity of the reported results.
Clinicopathology of non-infectious choroiditis: evolution of its appraisal during the last 2–3 decades from “white dot syndromes” to precise classification
Authors: Herbort Carl P. , Neri Piergiorgio , Papasavvas Ioannis 
Published: November 2021

AbstractChoroidal imaging investigation techniques were very limited until 2–3 decades ago.Fluorescein angiography (FA) was not suited for the analysis of the choroidal compartment and B-scan ultrasonography did not provide enough accuracy. It was on this background that a purely phenomenological approach was attempted to classify these choroiditis diseases by regrouping them under the vague potpourri term of “white dot syndromes”. With the availability of precise investigational modalities of choroidal inflammation or choroiditis-induced lesions, such as indocyanine green angiography (ICGA), spectral domain optical coherence tomography (SD-OCT) and enhanced depth imaging optical coherence tomography (EDI-OCT) it became possible to better classify these diseases based on clinico-pathological mechanisms rather than on purely phenomenological observation.Recently OCT-angiography has implemented the armamentarium of diagnostic techniques possibly also contributing to the classification of choroidal inflammatory diseases.Based on pioneering pragmatism, the aim of this article was to give a clear classification of non-infectious choroiditis. Thanks to new imaging investigations of the choroid, it is now possible to classify and understand the diverse clinicopathological mechanisms in the group of non-infectious choroiditis entities.

AbstractBackgroundMaternal obesity is a public health issue that could affect both women’s and children’s health. This qualitative study aimed to identify barriers to weight management of pregnant women with obesity and low socioeconomic backgrounds.MethodsThe current qualitative study has been conducted using a grounded theory approach by analyzing data collected from in-depth interviews with clients of Tehran’s public health care centers for prenatal care. The criteria for selecting participants were excessive weight gain during the first two trimesters of pregnancy, low socioeconomic status, and willingness to share their experiences. A semi-structured guide consisting of open-ended questions was asked in a private room. Open, axial, and selective coding were applied to the data.FindingsFour main themes emerged from data, each of which has some subcategories: 1) personal factors (unpleasant emotions and feelings, personal tastes/hobbies, workload and responsibilities, and history of diseases), 2) pregnancy status (unintended and high-risk pregnancy), 3) interpersonal relationships and support (lack of a spouse’s support and unhealthy role modeling of relatives), 4) socio-cultural factors/influences (social norms and values, lack of access to health services, and unreliable information channels).ConclusionsThis study provides an overview of the barriers to the weight management of pregnant women from low socioeconomic backgrounds. The results could help develop appropriate health strategies for low socioeconomic women with obesity. Also, health care providers for this group of women could use these findings as a guide to consider their conditions and background.

Abstract
Background
During pregnancy a high amount of fatty acids (FA) is necessary to meet foetus demands, which vary during gestation. The present study describes the changes in maternal fatty acid concentrations during pregnancy in a sample of pregnant women.

Methods
This is a longitudinal study of 479 pregnant women who were monitored from the first trimester to third trimester of pregnancy. Data on maternal characteristics were recorded and a serum sample was collected in each trimester. The fatty acid profile (saturated (SFA: total, lauric acid, myristic acid, palmitic acid, stearic acid), monounsaturated (MUFA: total, palmitoleic acid, oleic acid) and polyunsaturated fatty acids (PUFA: total omega-6 (n-6), linoleic acid, dihomo-γ-linolenic acid, arachidonic acid (AA), total omega-3 (n-3), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA)) was analysed with a gas chromatography-mass spectrometry combination.

Results
From the first trimester to third trimester of pregnancy, a significant increase in total SFA, total MUFA and total n-6 PUFA was found. (p < 0.001). Nevertheless, the serum concentration of arachidonic acid (AA), eicosapentaenoic acid (EPA) and total n-3 PUFA decreased during gestation (p < 0.001). A statistically non-significant result was observed for the docosahexaenoic acid (DHA) serum concentration between the first and third trimesters of pregnancy. Significant correlations were observed between each total fatty acid concentrations of the first and third trimesters.

Conclusion
The circulating serum concentration of SFA, MUFA and n-6 PUFA increases during pregnancy, whereas essential fatty acids such as AA and EPA decrease, and DHA remains unchanged. Further research is necessary to understand the role played by FA throughout gestation.
