Abstract
BACKGROUND The aim of the study is to evaluate the mortality risk factors and hospitalization outcomes of adenovirus pneumonia in pediatric patients with congenital heart disease. METHODS In this retrospective multicenter cohort study utilizing the Pediatric Health Information System database, we analyzed congenital heart disease patients with adenovirus pneumonia from January 2004 to September 2018, categorizing them into shunts, obstructive lesions, cyanotic lesions and mixing lesions. Multivariate logistic regression analysis was employed to identify mortality risk factors with 2 distinct models to mitigate collinearity issues and the Mann-Whitney U test was used to compare the hospital length of stay between survivors and nonsurvivors across these variables. RESULTS Among 381 patients with a mean age of 3.2 years (range: 0-4 years), we observed an overall mortality rate of 12.1%, with the highest mortality of 15.1% noted in patients with shunts. Model 1 identified independent factors associated with increased mortality, including age 0-30 days (OR: 8.13, 95% CI: 2.57-25.67, P < 0.005), sepsis/shock (OR: 3.34, 95% CI: 1.42-7.83, P = 0.006), acute kidney failure (OR: 4.25, 95% CI: 2.05-13.43, P = 0.0005), shunts (OR: 2.95, 95% CI: 1.14-7.67, P = 0.03) and cardiac catheterization (OR: 6.04, 95% CI: 1.46-24.94, P = 0.01), and Model 2, extracorporeal membrane oxygenation (OR: 3.26, 95% CI: 1.35-7.87, P = 0.008). Nonsurvivors had a median hospital stay of 47 days compared to 15 days for survivors. CONCLUSION The study revealed a 12.1% mortality rate in adenoviral pneumonia among children with congenital heart disease, attributed to risk factors such as neonates, sepsis, acute kidney failure, shunts, cardiac catheterization, extracorporeal membrane oxygenation use and a 3-fold longer hospital stay for nonsurvivors compared to survivors.

Accuracy of the Wound Healing Questionnaire in the diagnosis of surgical-site infection after abdominal surgery in low- and middle-income countries. Br J Surg 2024; 111:znad446. [PMID: 38747515 PMCID: PMC10895408 DOI: 10.1093/bjs/znad446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2023] [Revised: 09/07/2023] [Accepted: 10/12/2023] [Indexed: 05/19/2024]
Abstract
INTRODUCTION Telemedicine is being adopted for postoperative surveillance but requires evaluation for efficacy. This study tested a telephone Wound Healing Questionnaire (WHQ) to diagnose surgical site infection (SSI) after abdominal surgery in low- and middle-income countries. METHOD A multi-centre, international, prospective study was embedded in the FALCON trial; a factorial RCT testing measures to reduce SSI in seven low- and middle-income countries (NCT03700749). It was conducted according to a pre-registered protocol (SWAT126) and reported according to STARD guidelines. The reference test was in-person review by a trained clinician at 30 postoperative days according to US Centres for Disease Control criteria. The index test was telephone administration of an adapted WHQ at 27 to 30 postoperative days by a researcher blinded to the outcome of in-person review. The sum of item response scores generated an overall score between 0 and 29. The primary outcome was the diagnostic accuracy of the WHQ, defined as the proportion of SSI correctly identified by the telephone WHQ, and summarized using the area under the receiving operator characteristic curve (AUROC) and diagnostic test accuracy statistics. RESULTS Patients were included from three upper-middle income (396 patients, 13 hospitals), three lower-middle income (746 patients, 19 hospitals), and one low-income country (54 patients, 4 hospitals). 90.3% (1088 of 1196) patients were successfully contacted. Those with non-midline incisions (adjusted odds ratio: 0.36, 95% c.i. 0.17 to 0.73, P=0.005) or a confirmed diagnosis of SSI on in-person assessment (odds ratio: 0.42, 95% c.i. 0.20 to 0.92, P=0.006) were harder to reach. The questionnaire correctly discriminated between most patients with and without SSI (AUROC 0.869, 95% c.i. 0.824 to 0.914), which was consistent across subgroups. A representative cut-off score of ≥4 displayed a sensitivity of 0.701 (0.610-0.792), specificity of 0.911 (0.878-0.943), positive predictive value of 0.723 (0.633-0.814) and negative predictive value of 0.901 (0.867-0.935). CONCLUSION SSI can be diagnosed using a telephone questionnaire (obviating in-person assessment) in low resource settings.

Abstract
The presence of phosphorus in borosilicate glass (at 0.1 - 1.3 mol% P2O5) and in iron-phosphate glass (at 53 mol% P2O5) stimulated the growth and metabolic activity of anaerobic bacteria in model systems. Dissolution of these phosphorus containing glasses was either inhibited or accelerated by microbial metabolic activity, depending on the solution chemistry and the glass composition. The breakdown of organic carbon to volatile fatty acids increased glass dissolution. The interaction of microbially reduced Fe(II) with phosphorus-containing glass under anoxic conditions decreased dissolution rates, whereas the interaction of Fe(III) with phosphorus-containing glass under oxic conditions increased glass dissolution. Phosphorus addition to borosilicate glasses did not significantly affect the microbial species present, however, the diversity of the microbial community was enhanced on the surface of the iron phosphate glass. Results demonstrate the potential for microbes to influence the geochemistry of radioactive waste disposal environments with implication for wasteform durability.

A comparative study of outcomes of burns across multiple levels of care. Burns 2023; 49:1879-1885. [PMID: 37827938 DOI: 10.1016/j.burns.2023.03.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2022] [Revised: 02/13/2023] [Accepted: 03/05/2023] [Indexed: 03/14/2023]
Abstract
BACKGROUND Burn injuries are a significant contributor to the burden of diseases. The management of burns at specialised burn centres has been shown to improve survival. However, in low- and middle-income countries (LMICs) major burns are managed at non-specialised burn centres due to resource constraints. There is insufficient data on survival from treatment at non-specialised burn centres in LMICs. This study aimed to compare the outcomes of burns treatment between a specialised burn centre and five non-specialised centres. METHODS A prospective cohort study was conducted on patients aged 18 years or above from January 1, 2021 to September 30, 2021. Participants were selected from the admission register at the emergency department. All burns irrespective of the mechanism of injury or %TBSA were included. Data were entered into REDCap. Statistical analysis of outcomes such as positive blood culture, length of hospital stay (LOHS) and 90-day mortality between specialised burn versus non-specialised centres was performed. Furthermore, an analysis of risk factors for mortality was performed and survival data computed. RESULTS Of the 488 study participants, 36% were admitted to a specialised burn centre compared to 64% admitted to non-specialised centres. The demographic characteristics were similar between centres. Patients at the specialised burn centre compared to non-specialised centres had a significantly higher inhalation injury of 30.9% vs 7.7% (p < 0.001), > 10%TBSA at 83.4% vs 45.7% (p < 0.001), > 20%TBSA at 46.9% vs 16.6% (p < 0.001), and a median (IQR) ABSI score of 6 (5-7) vs 5 (4-6) (p < 0.0001). Furthermore, patients from specialised burn vs non-specialised centres had a longer median (IQR) time from injury to first burn excision at 7 (4-11) vs 5 (2-10) days, higher rate of burn sepsis 69% vs 35%, increased LOHS 17 (11-27) vs 12 (6-22) days, and 90-day mortality rates at 19.4% vs 6.4%. After adjusting for cofounding variables, survival data showed no difference between specialised burn and non-specialised centres (HR 1.8 95% CI 1.0-3.2, p = 0.05). CONCLUSION Although it appears that the survival of burn patients managed at non-specialised centres in a middle-income country is comparable to those managed at specialised burn centres, there is uncounted bias in our survival data. Hence, a change in practice is not advocated. However, due to resource constraint specialised burn centres in addition to managing major burns should provide training and support to the non-specialised centres.

Dysregulated energy metabolism impairs chondrocyte function in osteoarthritis. Osteoarthritis Cartilage 2022; 31:613-626.

Abstract
OBJECTIVES Metabolic pathways are a series of chemical reactions by which cells take in nutrient substrates for energy and building blocks needed to maintain critical cellular processes. Details of chondrocyte metabolism and how it rewires during the progression of osteoarthritis (OA) are unknown. This research aims to identify what changes in the energy metabolic state occur in OA cartilage. METHODS Patient matched OA and non-OA cartilage specimens were harvested from total knee replacement patients. Cartilage was first collected for metabolomics, proteomics, and transcriptomics analyses to study global alterations in OA metabolism. We then determined the metabolic routes by tracking [U-13C] isotope with liquid chromatography-mass spectrometry (LC-MS). We further evaluated cellular bioenergetic profiles by measuring oxygen consumption rate (OCR) and extracellular acidification rate (ECAR) and investigated the effects of low-dose and short-term effects of 2-deoxyglucose (2DG) on chondrocytes. RESULTS OA chondrocytes showed increased basal ECAR and more lactate production compared to non-OA chondrocytes. [U-13C] glucose labelling revealed that less glucose-derived carbon entered the tricarboxylic acid (TCA) cycle. On the other hand, mitochondrial respiratory rates were markedly decreased in the OA chondrocytes compared to non-OA chondrocytes. These changes were accompanied by decreased cellular ATP production, mitochondrial membrane potential and disrupted mitochondrial morphology. We further demonstrated in vitro that short-term inhibition of glycolysis suppressed matrix degeneration gene expression in chondrocytes and bovine cartilage explants cultured under inflammatory conditions. CONCLUSION This study represents the first comprehensive comparative analysis of metabolism in OA chondrocytes and lays the groundwork for therapeutic targeting of metabolism in OA.

Shock index as a prognosticator for emergent surgical intervention and mortality in trauma patients in Johannesburg: A retrospective cohort study. Ann Med Surg (Lond) 2021; 69:102710. [PMID: 34429962 PMCID: PMC8365323 DOI: 10.1016/j.amsu.2021.102710] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2021] [Revised: 08/06/2021] [Accepted: 08/07/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction Trauma is the leading cause of morbidity and mortality worldwide with exsanguination being the primary preventable cause through early surgical intervention. We assessed two popular trauma scoring systems, injury severity scores (ISS) and shock index (SI) to determine the optimal cut off values that may predict the need for emergent surgical intervention (ESI) and in-hospital mortality. Methods A retrospective analysis of patient records from a tertiary hospital's trauma unit for the year 2019 was done. Descriptive statistics, univariate and multivariate logistic regression analyses were performed. Receiver operator characteristic (ROC) curve analysis was conducted and area under the curve (AUC) reported for predicting the need for ESI in all study participants, as well as in patients with penetrating injuries alone, based on continuous variables of ISS, SI or a combination of ISS and SI. The Youdin Index was applied to determine the optimal ISS and SI cut off values. Results A total of 1964 patients’ records were included, 89.0% were male and the median age (IQR) was 30 (26–37) years. Penetrating injuries accounted for 65.9% of all injuries. ISS and SI were higher in the ESI group with median (IQR) 11 (10–17) and 0.74 (0.60–0.95), respectively. The overall mortality rate was 4.5%. The optimal cut-off values for ESI and mortality by ISS (AUC) were 9 (0.74) and 12 (0.86) (p = 0.0001), with optimal values for SI (AUC) being 0.72 (0.60), and 0.91 (0.68) (p = 0.0001), respectively. Conclusion ISS and SI are significant, independent prognosticators for the need of ESI and in-hospital mortality. The ISS cut-off of 15 for severe trauma may underestimate the severity of trauma within our local South African population. Our study reports an optimal SI cut off value of ≥0.72 for emergency surgical intervention. At an optimal SI cut off of ≥0.91 for in-hospital mortality, the odds of demise were 6.7 times higher. ISS was a stronger predictor than SI of both ESI and in-hospital mortality in our study.

Characterisation of ovine bone marrow-derived stromal cells (oBMSC) and evaluation of chondrogenically induced micro-pellets for cartilage tissue repair in vivo. Stem Cell Res Ther 2021; 12:26.

Abstract
Abstract Bone marrow stromal cells (BMSC) show promise in cartilage repair, and sheep are the most common large animal pre-clinical model. Objective The objective of this study was to characterise ovine BMSC (oBMSC) in vitro, and to evaluate the capacity of chondrogenic micro-pellets manufactured from oBMSC or ovine articular chondrocytes (oACh) to repair osteochondral defects in sheep. Design oBMSC were characterised for surface marker expression using flow cytometry and evaluated for tri-lineage differentiation capacity. oBMSC micro-pellets were manufactured in a microwell platform, and chondrogenesis was compared at 2%, 5%, and 20% O2. The capacity of cartilage micro-pellets manufactured from oBMSC or oACh to repair osteochondral defects in adult sheep was evaluated in an 8-week pilot study. Results Expanded oBMSC were positive for CD44 and CD146 and negative for CD45. The common adipogenic induction ingredient, 3-Isobutyl-1-methylxanthine (IBMX), was toxic to oBMSC, but adipogenesis could be restored by excluding IBMX from the medium. BMSC chondrogenesis was optimal in a 2% O2 atmosphere. Micro-pellets formed from oBMSC or oACh appeared morphologically similar, but hypertrophic genes were elevated in oBMSC micro-pellets. While oACh micro-pellets formed cartilage-like repair tissue in sheep, oBMSC micro-pellets did not. Conclusion The sensitivity of oBMSC, compared to human BMSC, to IBMX in standard adipogenic assays highlights species-associated differences. Micro-pellets manufactured from oACh were more effective than micro-pellets manufactured from oBMSC in the repair of osteochondral defects in sheep. While oBMSC can be driven to form cartilage-like tissue in vitro, the effective use of these cells in cartilage repair will depend on the successful mitigation of hypertrophy and tissue integration.

Abstract
OBJECTIVE To determine risk-reducing early salpingectomy and delayed oophorectomy (RRESDO) acceptability and effect of surgical prevention on menopausal sequelae/satisfaction/regret in women at increased ovarian cancer (OC) risk. DESIGN Multicentre, cohort, questionnaire study (IRSCTN:12310993). SETTING United Kingdom (UK). POPULATION UK women without OC ≥18 years, at increased OC risk, with/without previous RRSO, ascertained through specialist familial cancer/genetic clinics and BRCA support groups. METHODS Participants completed a 39-item questionnaire. Baseline characteristics were described using descriptive statistics. Logistic/linear regression models analysed the impact of variables on RRESDO acceptability and health outcomes. MAIN OUTCOMES RRESDO acceptability, menopausal sequelae, satisfaction/regret. RESULTS In all, 346 of 683 participants underwent risk-reducing salpingo-oophorectomy (RRSO). Of premenopausal women who had not undergone RRSO, 69.1% (181/262) found it acceptable to participate in a research study offering RRESDO. Premenopausal women concerned about sexual dysfunction were more likely to find RRESDO acceptable (odds ratio [OR] = 2.9, 95% CI 1.2-7.7, P = 0.025). Women experiencing sexual dysfunction after premenopausal RRSO were more likely to find RRESDO acceptable in retrospect (OR = 5.3, 95% CI 1.2-27.5, P < 0.031). In all, 88.8% (143/161) premenopausal and 95.2% (80/84) postmenopausal women who underwent RRSO, respectively, were satisfied with their decision, whereas 9.4% (15/160) premenopausal and 1.2% (1/81) postmenopausal women who underwent RRSO regretted their decision. HRT uptake in premenopausal individuals without breast cancer (BC) was 74.1% (80/108). HRT use did not significantly affect satisfaction/regret levels but did reduce symptoms of vaginal dryness (OR = 0.4, 95% CI 0.2-0.9, P = 0.025). CONCLUSION Data show high RRESDO acceptability, particularly in women concerned about sexual dysfunction. Although RRSO satisfaction remains high, regret rates are much higher for premenopausal women than for postmenopausal women. HRT use following premenopausal RRSO does not increase satisfaction but does reduce vaginal dryness. TWEETABLE ABSTRACT RRESDO has high acceptability among premenopausal women at increased ovarian cancer risk, particularly those concerned about sexual dysfunction.

Abstract
During January 1, 2020-May 18, 2020, approximately 1.3 million cases of coronavirus disease 2019 (COVID-19) and 83,000 COVID-19-associated deaths were reported in the United States (1). Understanding the demographic and clinical characteristics of decedents could inform medical and public health interventions focused on preventing COVID-19-associated mortality. This report describes decedents with laboratory-confirmed infection with SARS-CoV-2, the virus that causes COVID-19, using data from 1) the standardized CDC case-report form (case-based surveillance) (https://www.cdc.gov/coronavirus/2019-ncov/php/reporting-pui.html) and 2) supplementary data (supplemental surveillance), such as underlying medical conditions and location of death, obtained through collaboration between CDC and 16 public health jurisdictions (15 states and New York City).

Abstract
The capabilities of a radio-frequency atomic magnetometer for object detection based on magnetic induction tomography are explored. The determination of object orientation is demonstrated by utilizing the measurement geometry. The self-compensation configuration of the atomic magnetometer is implemented to address the issue of saturation of the sensor response by the radio-frequency primary field that generates the object signature. Three methods of "covert" detection are investigated as a testbed for exploring the functionalities of this sensor, where (1) the operational frequency of the sensor is continuously changed, (2) the primary field has non-monochromatic frequency distribution, and (3) the sensor operates in the so-called spin maser mode. The results of the measurements are also discussed in terms of possible magnetic field communication.

Abstract
Knee arthroscopy is a minimally invasive surgery used in the treatment of intra-articular knee pathology which may cause unintended damage to femoral cartilage. An ultrasound (US)-guided autonomous robotic platform for knee arthroscopy can be envisioned to minimise these risks and possibly to improve surgical outcomes. The first necessary tool for reliable guidance during robotic surgeries was an automatic segmentation algorithm to outline the regions at risk. In this work, we studied the feasibility of using a state-of-the-art deep neural network (UNet) to automatically segment femoral cartilage imaged with dynamic volumetric US (at the refresh rate of 1 Hz), under simulated surgical conditions. Six volunteers were scanned which resulted in the extraction of 18278 2-D US images from 35 dynamic 3-D US scans, and these were manually labelled. The UNet was evaluated using a five-fold cross-validation with an average of 15531 training and 3124 testing labelled images per fold. An intra-observer study was performed to assess intra-observer variability due to inherent US physical properties. To account for this variability, a novel metric concept named Dice coefficient with boundary uncertainty (DSCUB) was proposed and used to test the algorithm. The algorithm performed comparably to an experienced orthopaedic surgeon, with DSCUB of 0.87. The proposed UNet has the potential to localise femoral cartilage in robotic knee arthroscopy with clinical accuracy.

Abstract
A collaborative study was conducted to compare the VIDAS Salmonella (SLM) with Rappaport-Vassiliadis (RV) method for detection of Salmonella in foods to the current standard method presented in the U.S. Food and Drug Administration's Bacteriological Analytical Manual (BAM) and the culture method presented in AOAC's Official Methods of Analysis. The VIDAS SLM with RV method uses tetrathionate broth in combination with RV medium in place of selenite cystine broth for selective enrichment, thereby eliminating the hazardous waste issue for laboratories. Twenty five laboratories participated in the evaluation, each testing one or more of 8 test products: nonfat dry milk, dried egg, soy flour, lactic casein, milk chocolate, raw ground pork, raw ground turkey, and raw peeled shrimp. Results of the study showed no significant differences in the numbers of confirmed positive samples with the VIDAS SLM with RV procedure and the BAM/AOAC culture procedure. The VIDAS SLM with RV method was effective for rapid detection of Salmonella in foods. It is recommended that AOAC INTERNATIONAL modify the VIDAS Salmonella SLM procedure to include the RV method.

Whole-Exome Sequencing Reveals Frequent Mutations in Chromatin Remodeling Genes in Mammary and Extramammary Paget's Diseases. J Invest Dermatol 2019; 139:789-795.

Abstract
Paget's disease (PD) is an intraepidermal adenocarcinoma of the skin at the breast (mammary PD) or urogenital locations (extramammary PD [EMPD]). At present, there is lack of clarity on PD's pathogenesis, the relationship between its subtypes, and its lineage link with the underlying invasive carcinomas. Here we describe that mammary PD and EMPD have similar mutational profiles, with the most frequent recurrent mutations occurring in the chromatin remodeling genes, such as KMT2C (MLL3, 39%) and ARID2 (22%), with additional recurrent somatic mutations detected in genes previously not known to be mutated in cancers, such as CDCC168 (34%), FSIP2 (29%), CASP8AP2 (29%), and BIRC6 (24%). In paired mammary PD and underlying breast carcinoma samples, distinct gene mutations were detected, indicating that they represent independent oncogenic events. Finally, multistage EMPD tissue sequencing revealed KMT2C gene occurring early in EMPD oncogenesis, and that multifocal EMPD samples share the same early gene mutations, suggesting clonal origin of multifocal EMPD. Our results reveal similar genomic landscapes between mammary PD and EMPD, including early aberrations in chromatin remodeling genes. In addition, mammary PD and underlying breast ductal carcinomas represent independent oncogenic events. These findings provide approaches for developing diagnostic tools and therapeutic interventions for PD.

Abstract
Paget's disease (PD) is an uncommon intraepithelial adenocarcinoma with unknown pathogenesis. There are two anatomic subtypes: mammary (MPD) and extramammary (EMPD). Little is known about their molecular characteristics. Our objective was to discover novel molecular markers for PD and its subtypes. In the discovery phase, we used transcriptome analyses to uncover the most differentially expressed genes and pathways in EMPD biopsies compared with normal skin. In the validation phase, we performed immunohistochemistry analyses on the most promising marker (FOXA1) and other markers selected from a literature review (GATA3, estrogen receptor [ER], and androgen receptor [AR]) on independent biopsies of MPD (n = 86), EMPD (n = 59), and normal skin (n = 21). Transcriptome analyses revealed 210 genes differentially expressed more than 10-fold between EMPD and normal skin. These genes are involved in mammary and sweat gland development (FOXA1) and immune regulation, as well as epidermal differentiation. Immunohistochemistry staining revealed that FOXA1 was positive in 88% of both MPD and EMPD, whereas GATA3 was positive in 67% of MPD and 77% of EMPD, and ER was positive in 9% of MPD and 19% of EMPD. Finally, AR was positive in 33% of PD and 54% of EMPD. Mammary Paget's disease and EMPD share dysregulation of the glandular developmental regulator gene FOXA1, suggesting similarity in cell-specific transcriptional regulation. Further, FOXA1 may be a useful molecular target for developing PD therapies.

Abstract
Background Primary schools are increasingly used as arenas for public health initiatives. The aim of this study was to assess a primary school-based food intervention. Methods The intervention comprised timetabled kitchen classroom sessions (90 min, fortnightly). Pupils prepared and cooked food, which they then ate together. Children's relationship with food, including food enjoyment, experience and food neophobia, were addressed at the intervention school (baseline n = 154; follow-up n = 164) and at a matched control school (baseline n = 171; follow-up n = 174). Results Pupils at the intervention school scored significantly higher (M = 3.90, SD = 1.81) for scores on Kitchen Equipment, compared to the control school (M = 3.06, SD = 2.12); and again scored significantly higher (M = 9.34, SD = 3.79) for the overall Cooking Experience Score compared to the control school (M = 7.98, SD = 4.57). Shifts accompanying the intervention in three outcome measures for pupils (taste description, liking for cooking and helping with cooking at home) were also revealed. No main intervention effect for food neophobia and fussiness was found; a close to significant time by intervention interaction (P = 0.053) was evident. Conclusions The study indicates limited but encouraging changes, and contributes to the growing literature regarding school-based food initiatives.

Abstract
The MAGnetic Expansion Control (MAGEC) system is used increasingly in the management of early-onset scoliosis. Good results have been published, but there have been recent reports identifying implant failures that may be associated with significant metallosis surrounding the implants. This article aims to present the current knowledge regarding the performance of this implant, and the potential implications and strategies that may be employed to identify and limit any problems. We urge surgeons to apply caution to patient and construct selection; engage in prospective patient registration using a spine registry; ensure close clinical monitoring until growth has ceased; and send all explanted MAGEC rods for independent analysis. The MAGEC system may be a good instrumentation system for the treatment of early-onset scoliosis. However, it is innovative and like all new technology, especially when deployed in a paediatric population, robust systems to assess long-term outcome are required to ensure that patient safety is maintained.

Chondromodulin-1 ameliorates osteoarthritis progression by inhibiting HIF-2α activity. Osteoarthritis Cartilage 2016; 24:1970-1980.

Abstract
OBJECTIVES Hypoxia is known to stabilize hypoxia-inducible factor (HIF) and initiate angiogenic signaling cascade. However, cartilage living in hypoxia environment can maintain avascularity. It is well known that abrogation of avascularity is related to cartilage degradation in osteoarthritis (OA). The aims of present study were to investigate the role of chondromodulin-1 (ChM-1), an endogenously anti-angiogenic protein in cartilage, during chondrocyte maturation and OA progression, as well as to explore the molecular mechanisms underlying the function of ChM-1 with a focus on HIF-2α pathway. METHODS Angiogenic-related markers were evaluated in OA cartilage and different stages of chondrocyte differentiation. Chondrocytes transfected with ChM-1 lentivirus or siRNA was treated with tumor necrosis factor (TNF-α) to investigate the role of ChM-1 in chondrocyte hypertrophic changes. In vivo study was conducted by using a surgical induced OA rat model with intra-articular injection of lentivirus ChM-1 (LV-ChM-1) or mock lentivirus (LV-GFP) control. Transcriptional activity of HIF-2α was determined by chromatin immunoprecipitation (ChIP) assay to unveil the mechanisms of ChM-1. RESULTS Majority angiogenic factors increased in severe OA cartilage, while anti-angiogenic factors including ChM-1 decreased. ChM-1 expression was strongly related with chondrocyte differentiation and chondrogenesis in vitro. ChM-1 overexpression protected chondrocytes from TNF-α induced hypertrophy, and intra-articular injection of LV-ChM-1 delayed OA progression. ChM-1 delayed HIF-2α nuclear translocation at early time-points and decreased transcriptional activity of HIF-2α on collagen type Х α1 (COL10A1), vascular endothelial growth factor A (VEGFA) and matrix metallopeptidase-13 (MMP-13). CONCLUSIONS ChM-1 maintains cartilage homeostasis by inhibiting HIF-2α induced catabolic activity and regulation of ChM-1 in cartilage may be a promising therapeutic strategy for OA.

Abstract
OBJECTIVES In late 2013, an Ebola outbreak quickly grew into an epidemic of extraordinary magnitude, killing more people than all previous Ebola outbreaks combined. Although the epidemic was unprecedented, the world had previously experienced several acute public health emergencies requiring global coordination. HIV/AIDS, SARS and H1N1 tested global response, and in each case coordination proved problematic, making the 2013-2015 Ebola epidemic no exception. The purpose of this project was to identify persistent vulnerabilities within global public health emergency response and to identify areas for future research and improvement. STUDY DESIGN Non-systematic review and qualitative interview study. METHODS Using PubMed and Google, a comprehensive search of articles connected to the HIV/AIDS, SARS, H1N1 and Ebola responses was conducted. Then, 21 key responders involved in those emergencies, primarily from the US Centers for Disease Control and Prevention, participated in in-depth interviews. The content analysis and in-depth interview data were analysed using MAXQDA analysis software. RESULTS A number of issues emerged, including cultural and political clashes within relevant agencies and a lack of confidence in those agencies, policy barriers that hinder long-term international response, a shortage of personnel and resources, itemized funding streams that limit flexibility to direct resources, and challenges to deploying responders internationally. CONCLUSIONS The data suggest that the world remains ill prepared to handle sustained responses and global pandemics. The study identified major vulnerabilities persistent within US-led global public health response and offers recommendations for further focused research to fully understand why these challenges persist.

Abstract
Revision of a cemented femoral stem can be a challenging procedure. We present a series of cases utilising the "In-cement" revision, whereby the same size stem is introduced into the original cement mantle, without additional cementing. It requires a stable cement mantle in the correct version. We describe the technique and present a review of 23 revision total hip replacements performed over a 5 year period. At average follow-up of 67 months (12-128 months), the overall survivorship was 91.3% with no patient requiring re-revision for stem loosening or mechanical failure. Two patients required re-revision for infection and one of those patients is now deceased. No further operations were required in 21 patients. The "In-cement" revision can be a valuable technique for the revision arthroplasty surgeon. Early results suggest this is a safe and effective technique in the appropriate patient.

Abstract
This study explored the impact of a school-based kitchen project at a large inner London school. Timetabled kitchen classroom sessions (90 min every fortnight) were held with all 7-9 year old pupils. Semi-structured focus group discussions (with 76 pupils, 16 parents) and interviews (with headteachers, catering managers and specialist staff) were conducted at the intervention school and a matched control school. Categories and concepts were derived using a grounded theory approach. Data analysis provided three main categories each with their related concepts: Pupil factors (enthusiasm and enjoyment of cooking, trying new foods, food knowledge and awareness, producing something tangible); School factors (learning and curriculum links, resource implications and external pressures) and Home factors (take home effects, confidence in cooking and self-esteem, parents' difficulties cooking at home with children). Children's engagement and the opportunity to cook supported increased food awareness, skills and food confidence. In the grounded theory that emerged, take home effects beyond the school gate dominate, as children act as agents of change and influence cooking and food choice at home. These short term outcomes have the potential to lead to longer term outcomes including changing eating behaviour and diet.

Abstract
Anal cancer is uncommon, with an incidence rate of 0.5-1.0 per 100,000 of the population but incidence rates have been steadily increasing over the last 3 decades. Biological and epidemiological evidence have been mounting and demonstrate that anal cancer has many similarities to cervical cancer, especially in regard to its aetiology. High-resolution anoscopy (HRA) of the anal region – analogous to colposcopy of the cervix, is a technique that is not well-known in the medical and surgical fraternity. Evidence to support the use of HRA for detection and treatment in the surveillance of AIN exists and strongly suggests that it is beneficial, resulting in reduced rates of cancer progression. Pilot data from our study showed a local disease failure rate of 1.73 per 1000 patient-months compared with a published rate of 9.89 per 1000 patient-months. This demonstrates a 5.72-fold reduction in local disease failure rates of patients with T1-T3 tumours; the data therefore suggests that use of HRA for detection and treatment in surveillance of anal cancer patients will help prevent local regional relapse at the anal site. There is an urgent need for a large, randomised controlled clinical trial to definitively test this hypothesis.

Abstract
OBJECTIVE This study examines the impact of excision margin status after large loop excision of the transformation zone (LLETZ) under local anaesthetic for high-grade cervical intraepithelial neoplasia (HG-CIN) on the cytological and histological outcomes up to 5 years after treatment. METHODS Prospective cytological and histological data were obtained by examination of the colposcopy database at Addenbrooke's Hospital, Cambridge, UK. All women aged between 19 and 50 years who underwent treatment for HG-CIN by LLETZ under local anaesthetic were included in the study. Patients without follow-up data were excluded from the study. The excision margin status was correlated with the subsequent cytological and histological outcomes. RESULTS A series of 967 women with CIN2 and CIN3 underwent LLETZ excision under local anaesthetic. Overall, 42% of women had disease present at the excision margin following LLETZ. Women with CIN3 were more likely than those with CIN2 to have an involved excision margin (P<0.0001). Cytological recurrence was highest at 12 months (16%) and did not correlate with the CIN grade or excision margin status. Histological recurrence/persistence was also highest at 12 months follow-up (15%) and this correlated with grade of CIN and margin status (P<0.0001). CONCLUSIONS Histological recurrence/persistence correlates with grade of CIN and excision margin status. Management of HG-CIN in an outpatient setting under local anaesthetic is safe, cost effective and yields a favourable long-term outcome.
