Abstract
Chronic skin wounds decrease the quality of life of millions of diabetic patients worldwide. Chitosan has previously been shown to possess hemostatic properties, decrease inflammation, promote fibroblast proliferation, and hair growth. We developed a relatively low-cost polyelectrolyte complex (PEC) film dressing made of chitosan and polygalacturonic acid and tested it for its ability to accelerate diabetic wound healing. Genetically diabetic male mice were shaved on the dorsum, and one day later a 1 cm diameter full-thickness excisional wound was created. The PEC film was applied immediately after wounding and left in place for 14 days. Controls consisted of wounds treated with a fibrin gel. Wounds covered with the PEC film had closed completely by post-wounding day 42, while untreated wounds were only half-way closed. Histological analysis of wounds confirmed that PEC-treated wounds had fully re-epithelialized, while control wounds lacked a continuous epidermis at the wound center. We also observed that the area of skin under the PEC film experienced much more rapid hair growth. Histologically, there were significantly more hair follicles around the scar area (p < 0.05) in the PEC-treated group as compared to the control group. Thus, chitosan-polygalacturonic acid PEC films can accelerate both wound healing and hair growth in diabetic mice, and should be further investigated as a potential future treatment for diabetic chronic wounds.

National evaluation of harm associated with patient safety incident reports related to the provision of parenteral nutrition to patients, using a national incident reporting system. Nutr Clin Pract 2023; 38:1392-1408. [PMID: 37063048 DOI: 10.1002/ncp.10989] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 02/06/2023] [Accepted: 03/13/2023] [Indexed: 04/18/2023] Open
Abstract
BACKGROUND Parenteral nutrition (PN)-related patient safety incidents have been associated with harm. Large-scale studies are scarce, and little is known about contributory factors. This study evaluated PN-related incident reports that described harm using a national database. MATERIALS AND METHODS A retrospective evaluation of incident reports involving PN in England and Wales reported to the National Reporting and Learning System between 2015 and 2020. We described frequency by degree of reported harm and incident characteristics. Content analysis was undertaken to understand contributory factors for reports related to moderate/severe harm or death. RESULTS 12,907 incident reports were identified. After screening, 2242 were evaluated; 1879 (83.8%) reported no harm, 309 (13.8%) low harm, 47 (0.02%) moderate harm, 4 (0.002%) severe harm, 3 (0.001%) deaths. The most reported age group, medication process, and error category were neonates (<28 days) (n = 570/1923, 29.6%), administration (n = 1126/2242, 50%), and omitted medication/ingredient (n = 291/2242, 13%), respectively. Content analysis of reports related to moderate/severe harm and death revealed patient age of <1 year, dependence on home PN (HPN), comorbidities, and staff errors as contributory factors. CONCLUSIONS This is the first evaluation of PN-related incident reports in England and Wales to our knowledge. We demonstrated a low frequency of reports related to moderate or severe harm or death. More incidents were reported for neonates and during the administration processes. To reduce harm, systems/procedures that reduce errors in high-risk patients (eg, neonates, patients receiving HPN) need to be established within organizations. Database limitations of voluntary reporting systems were recognized.

Expanded statistical analysis of squats on the Great Britain (GB) mainline network. Heliyon 2023; 9:e21112. [PMID: 37954362 PMCID: PMC10632690 DOI: 10.1016/j.heliyon.2023.e21112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 10/13/2023] [Accepted: 10/16/2023] [Indexed: 11/14/2023] Open
Abstract
Squat defects are one of the most common rail surface defects. Significant research effort has gone into understand squat defects over the last 10 years which has brought about important developments in the understanding of their initiation mechanism; however, further work is still required to fully understand squat and the best methods to control them. This study considers records of squat defects over a period 9 years, considering 2600 km of track across 8 different routes on the GB mainline network. The analysis separately reviews squats on: plainline, crossings, joints and welds. Results include an overview of the main factors influencing the development of each type of squats, practical methods to immediately reduce and manage squat defects and recommends focus areas for further research to understand squat defects. Results suggest that squats on plainline, crossings, joints and welds, all correlate with different influencing factors; headcheck defects appear to significantly influence the probability of squats and how other factors influence squat development. There is a strong connection between total head wear rate (combined material removal due to traffic and grinding) and squats; 90 % of all squats appear on rail with a headwear rate of <0.2 mm/year. Overall larger section rail (60 kg/m vs 56 kg/m) and harder material (260 Brinell vs 220 Brinell) is significantly less susceptible to squat damage. Track curvature has an influence of squat development, especially in rail with no headcheck cracking, where the tightest curves are significantly more likely to sustain squat damage. The probability of squat at vertical discontinuities, i.e. joints and crossings are significantly more likely as train speed increases. Whilst squats on joints are 1000 time more likely than squats on welds.

Abstract
The immune system plays a significant role in the development, invasion, progression, and metastasis of head and neck cancer. Over the last decade, the emergence of immunotherapy has irreversibly altered the paradigm of cancer treatment. The current treatment modalities for head and neck squamous cell carcinoma (HNSCC) include surgery, radiotherapy, and adjuvant or neoadjuvant chemotherapy which has failed to provide satisfactory clinical outcomes. To encounter this, there is a need for a novel or targeted therapy such as immunological targets along with conventional treatment strategy for optimal therapeutic outcomes. The immune system can contribute to promoting metastasis, angiogenesis, and growth by exploiting the tumor's influence on the microenvironment. Immunological targets have been found effective in recent clinical studies and have shown promising results. This review outlines the important immunological targets and the medications acting on them that have already been explored, are currently under clinical trials and are further being targeted.

A review of efficacy and safety of cetuximab and bevacizumab-based monoclonal antibodies in head and neck cancer. MEDICAL ONCOLOGY (NORTHWOOD, LONDON, ENGLAND) 2022; 40:66. [PMID: 36583766 DOI: 10.1007/s12032-022-01939-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Accepted: 12/19/2022] [Indexed: 12/31/2022]
Abstract
A combination of monoclonal antibodies prescribed along with the conventional standard of care has a potential to provide significant improvement in patients suffering from head and neck cancer. This combination has also shown a significant decrease in toxicities and improved overall quality of life. Cetuximab acts by inhibiting the human epidermal growth factors as its overexpression in head and neck tumours that are responsible for treatment failure, resistance, and metastasis. Whereas, bevacizumab acts by inhibiting the vascular endothelial growth factor since its overexpression leads to induction of tumour angiogenesis. Current research has not shown any remarkable beneficial effect in disease outcomes. Thus, the addition of these monoclonal antibodies to the standard regimen for head and neck cancer can be considered a prospect that might be beneficial. Cetuximab has already been included as an option under special recommendations in recurrent/metastatic head and neck cancer by NCCN in a platinum-based regimen as well as in combination with radiation therapy. This review outlines the applicability of cetuximab and bevacizumab in the treatment of head and neck cancer as well as the clinical trials performed that give an idea about the efficacy and safety of these monoclonal antibodies. Based upon the literature reviewed, it can be deduced that immunotherapy is to be adopted and different targets are to be explored in it in order to combat head and neck cancer. Currently, immunotherapeutic drugs of two major targets have been discussed. These agents are even effective in combination with other therapeutic modalities that are not being able to achieve desirable outcomes due to issues such as resistance and toxicities. Thus, newer targets as well as newer agents acting on established targets are to be explored in order to improve disease outcomes.

Abstract
Tuberculosis is a stern, difficult to treat chronic infection caused by acid-fast bacilli that tend to take a long time to be eradicated from the host’s environment. It requires the action of both innate and adaptive immune systems by the host. There are various pattern recognition receptors present on immune cells, which recognize foreign pathogens or its product and trigger the immune response. The epigenetic modification plays a crucial role in triggering the susceptibility of the host towards the pathogen and activating the host’s immune system against the invading pathogen. It alters the gene expression modifying the genetic material of the host’s cell. Epigenetic modification such as histone acetylation, alteration in non-coding RNA, DNA methylation and alteration in miRNA has been studied for their influence on the pathophysiology of tuberculosis to control the spread of infection. Despite several studies being conducted, many gaps still exist. Herein, we discuss the immunopathophysiological mechanism of tuberculosis, the essentials of epigenetics and the recent encroachment of epigenetics in the field of tuberculosis and its influence on the outcome and pathophysiology of the infection.

The influence of anastomotic techniques on postoperative anastomotic complications: Results of the Oesophago-Gastric Anastomosis Audit. J Thorac Cardiovasc Surg 2022; 164:674-684.e5. [PMID: 35249756 DOI: 10.1016/j.jtcvs.2022.01.033] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2021] [Revised: 12/22/2021] [Accepted: 01/18/2022] [Indexed: 12/08/2022]
Abstract
BACKGROUND The optimal anastomotic techniques in esophagectomy to minimize rates of anastomotic leakage and conduit necrosis are not known. The aim of this study was to assess whether the anastomotic technique was associated with anastomotic failure after esophagectomy in the international Oesophago-Gastric Anastomosis Audit cohort. METHODS This prospective observational multicenter cohort study included patients undergoing esophagectomy for esophageal cancer over 9 months during 2018. The primary exposure was the anastomotic technique, classified as handsewn, linear stapled, or circular stapled. The primary outcome was anastomotic failure, namely a composite of anastomotic leakage and conduit necrosis, as defined by the Esophageal Complications Consensus Group. Multivariable logistic regression modeling was used to identify the association between anastomotic techniques and anastomotic failure, after adjustment for confounders. RESULTS Of the 2238 esophagectomies, the anastomosis was handsewn in 27.1%, linear stapled in 21.0%, and circular stapled in 51.9%. Anastomotic techniques differed significantly by the anastomosis sites (P < .001), with the majority of neck anastomoses being handsewn (69.9%), whereas most chest anastomoses were stapled (66.3% circular stapled and 19.3% linear stapled). Rates of anastomotic failure differed significantly among the anastomotic techniques (P < .001), from 19.3% in handsewn anastomoses, to 14.0% in linear stapled anastomoses, and 12.1% in circular stapled anastomoses. This effect remained significant after adjustment for confounding factors on multivariable analysis, with an odds ratio of 0.63 (95% CI, 0.46-0.86; P = .004) for circular stapled versus handsewn anastomosis. However, subgroup analysis by anastomosis site suggested that this effect was predominantly present in neck anastomoses, with anastomotic failure rates of 23.2% versus 14.6% versus 5.9% for handsewn versus linear stapled anastomoses versus circular stapled neck anastomoses, compared with 13.7% versus 13.8% versus 12.2% for chest anastomoses. CONCLUSIONS Handsewn anastomoses appear to be independently associated with higher rates of anastomotic failure compared with stapled anastomoses. However, this effect seems to be largely confined to neck anastomoses, with minimal differences between techniques observed for chest anastomoses. Further research into standardization of anastomotic approach and techniques may further improve outcomes.

Abstract
BackgroundEULAR Sjögren’s syndrome disease activity index (ESSDAI) assesses systemic disease activity in patients (pts) with primary Sjögren’s syndrome (pSS); however, weaknesses include exclusion of patient-reported symptoms, tear and salivary gland function, and a marked placebo (PBO) response. Composite of Relevant Endpoints for Sjögren’s Syndrome (CRESS) is a recently developed composite outcome measure validated using data from three Phase 3 randomised controlled trials of pts with pSS.1 Concise CRESS (cCRESS) is used when ocular staining score and salivary gland ultrasonography are unavailable. ESSDAI was an endpoint in a Phase 2, PBO-controlled study, evaluating the safety and efficacy of belimumab (BEL) and rituximab (RTX) sequential administration (BEL/RTX), and BEL and RTX monotherapies in pts with pSS. Although the results numerically favoured BEL/RTX over PBO, this was not statistically significant.ObjectivesTo evaluate the efficacy of BEL/RTX and monotherapies using cCRESS overall responses at Weeks (Wks) 24, 52, and 68, and individual item responses at Wk 24 in pts with pSS who completed the Phase 2 study.MethodsIn the Phase 2, double-blind, 68-Wk study (NCT02631538) adults were randomised (2:2:2:1) into 4 treatment arms: BEL/RTX (n=24; weekly BEL 200 mg subcutaneous [SC] to Wk 24 followed by weekly PBO SC to Wk 52 + RTX 1000 mg intravenous [IV], Wk 8 + 10), BEL monotherapy (n=24; weekly BEL 200 mg SC to Wk 52), RTX monotherapy (n=25; RTX 1000 mg IV, Wk 8 + 10), or PBO (n=13). Pts were classified post hoc as cCRESS responders when ≥3 of the following 5 items were met: 1) Clinical (Clin)ESSDAI score <5 (low disease state); 2) decrease of ≥1 point or ≥15% from baseline (BL) in EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI); 3) increase of ≥5 mm from BL in abnormal Schirmer’s test, or no change to abnormal if normal at BL; 4) unstimulated whole saliva (UWS) increase of ≥25% from BL, or any increase from BL if score was 0 at BL; 5) decrease of ≥25% in the rheumatoid factor (RF) titre from BL, or decrease of ≥10% in IgG from BL.1ResultsOf 86 randomised pts, 60 completed follow-up to Wk 68 (completer population) and were included in the analysis. Most pts were female (95%, n=57); mean (SD) age was 49.6 (13.0) years. BL disease characteristics are presented in the Table 1.Table 1.Clinical, functional, and laboratory parameters at BL and cCRESS responders at Wks 24, 52, and 68 (completer population)PBO (n=8)BEL/RTX (n=17)BEL (n=19)RTX (n=16)Pt parameters at BL, mean (SD)ClinESSDAI11.1 (3.76)11.7 (5.47)9.2 (3.77)11.7 (4.76)ESSPRI6.4 (2.05)6.0 (1.97)6.5 (1.68)5.9 (2.20)Schirmer, mm/5 min2.7 (3.25)5.3 (6.44)3.3 (3.16)2.8 (3.15)UWS, ml/min0.1 (0.11)0.1 (0.12)0.1 (0.09)0.1 (0.14)RF, KU/l60.8 (42.24)30.9 (38.20)37.0 (34.98)105.0 (200.97)IgG, g/l20.4 (6.65)16.7 (5.00)18.1 (7.19)16.5 (6.09)cCRESS responders, n (%)Wk 244 (50.0)9 (52.9)7 (36.8)5 (31.3)Wk 524 (50.0)10 (58.8)8 (42.1)4 (25.0)Wk 681 (12.5)6 (35.3)7 (36.8)3 (18.8)At Wks 24 and 52, the proportion of cCRESS responders was numerically higher with BEL/RTX than with either BEL, RTX, or PBO, but the difference was not significant (Table 1). At Wk 68, the proportion of cCRESS responders was numerically higher with BEL/RTX than with RTX or PBO (Table 1). The 5 cCRESS items contributed relatively equally to total cCRESS response, with the highest response observed in the RF/IgG item and the lowest in the tear gland item (Schirmer’s test; Figure 1).Figure 1.cCRESS and individual item responders at Wk 24 (completer population)ConclusionAt Wks 24, 52, and 68, BEL/RTX was generally associated with a numerically higher cCRESS response rate compared with the monotherapies or PBO. The PBO response for cCRESS was notable and similar to the PBO response for ClinESSDAI. The PBO response in the tear and salivary gland items was greater than in the other treatment arms, perhaps due to the use of cCRESS instead of CRESS. Due to the small sample size, the results should be interpreted with caution.References[1]Arends S, et al.

Abstract
Abstract
Background
Textbook outcome has been proposed as a tool for the assessment of oncological surgical care. However, an international assessment in patients undergoing oesophagectomy for oesophageal cancer has not been reported. This study aimed to assess textbook outcome in an international setting.
Methods
Patients undergoing curative resection for oesophageal cancer were identified from the international Oesophagogastric Anastomosis Audit (OGAA) from April 2018 to December 2018. Textbook outcome was defined as the percentage of patients who underwent a complete tumour resection with at least 15 lymph nodes in the resected specimen and an uneventful postoperative course, without hospital readmission. A multivariable binary logistic regression model was used to identify factors independently associated with textbook outcome, and results are presented as odds ratio (OR) and 95 per cent confidence intervals (95 per cent c.i.).
Results
Of 2159 patients with oesophageal cancer, 39.7 per cent achieved a textbook outcome. The outcome parameter ‘no major postoperative complication’ had the greatest negative impact on a textbook outcome for patients with oesophageal cancer, compared to other textbook outcome parameters. Multivariable analysis identified male gender and increasing Charlson comorbidity index with a significantly lower likelihood of textbook outcome. Presence of 24-hour on-call rota for oesophageal surgeons (OR 2.05, 95 per cent c.i. 1.30 to 3.22; P = 0.002) and radiology (OR 1.54, 95 per cent c.i. 1.05 to 2.24; P = 0.027), total minimally invasive oesophagectomies (OR 1.63, 95 per cent c.i. 1.27 to 2.08; P < 0.001), and chest anastomosis above azygous (OR 2.17, 95 per cent c.i. 1.58 to 2.98; P < 0.001) were independently associated with a significantly increased likelihood of textbook outcome.
Conclusion
Textbook outcome is achieved in less than 40 per cent of patients having oesophagectomy for cancer. Improvements in centralization, hospital resources, access to minimal access surgery, and adoption of newer techniques for improving lymph node yield could improve textbook outcome.

Abstract
INTRODUCTION There is limited comprehensive literature focussing on the range of patient safety incidents related to parenteral nutrition (PN). OBJECTIVE The aim of this review was to examine patient safety incidents related to the use of PN in all patient age groups. METHODS Literature published in the English language between January 2000 and April 2020 were searched across the MEDLINE, CINHAL and Embase databases. Articles were included if they contained PN-related patient safety incidents related to an avoidable event. No restrictions were applied to patient populations. The screening process was undertaken independently by two authors. RESULTS In total, 108 records were included in the review: 52 case studies, 54 observation studies (e.g. prevalence studies, surveys) and two experimental studies. All age groups were represented, with 62% of studies in paediatrics (of which two-thirds were neonates) and 23% in adults. They included all medication processes: prescribing, dispensing, compounding, administration and monitoring. Incidents were related to microbial contamination, venous access and specific components (e.g. lipid emulsion, amino acids, glucose, micronutrients and electrolytes) or the whole product. Incident outcomes ranging from near miss to death were reported. Intervention studies looked at the impact on patient safety incidents of computerised tools, healthcare processes, e.g. pharmacist screening, and standardisation. One study demonstrated more severe outcomes with paediatric than with adult PN. CONCLUSIONS This review demonstrates the vast range of PN-related patient safety incidents in all patient age groups and all medication process stages. The need for a national study looking at patient safety incidents related to PN in England is highlighted.

[PMID: 35038327 PMCID: PMC8763367 DOI: 10.1093/bjsopen/zrab132] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Accepted: 11/15/2021] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The complexity of oesophageal surgery and the significant risk of morbidity necessitates that oesophagectomy is predominantly performed by a consultant surgeon, or a senior trainee under their supervision. The aim of this study was to determine the impact of trainee involvement in oesophagectomy on postoperative outcomes in an international multicentre setting. METHODS Data from the multicentre Oesophago-Gastric Anastomosis Study Group (OGAA) cohort study were analysed, which comprised prospectively collected data from patients undergoing oesophagectomy for oesophageal cancer between April 2018 and December 2018. Procedures were grouped by the level of trainee involvement, and univariable and multivariable analyses were performed to compare patient outcomes across groups. RESULTS Of 2232 oesophagectomies from 137 centres in 41 countries, trainees were involved in 29.1 per cent of them (n = 650), performing only the abdominal phase in 230, only the chest and/or neck phases in 130, and all phases in 315 procedures. For procedures with a chest anastomosis, those with trainee involvement had similar 90-day mortality, complication and reoperation rates to consultant-performed oesophagectomies (P = 0.451, P = 0.318, and P = 0.382, respectively), while anastomotic leak rates were significantly lower in the trainee groups (P = 0.030). Procedures with a neck anastomosis had equivalent complication, anastomotic leak, and reoperation rates (P = 0.150, P = 0.430, and P = 0.632, respectively) in trainee-involved versus consultant-performed oesophagectomies, with significantly lower 90-day mortality in the trainee groups (P = 0.005). CONCLUSION Trainee involvement was not found to be associated with significantly inferior postoperative outcomes for selected patients undergoing oesophagectomy. The results support continued supervised trainee involvement in oesophageal cancer surgery.

Abstract
Abstract
Aim
Orthognathic surgery corrects craniofacial deformity which compromises breathing or masticatory function. Patients typology influences their expectations for physical and psychological transformation before and after surgery and is an emerging area of research. This study aims to evaluate: 1) subjective expectations and/or perceived outcomes and 2) whether orthognathic surgery meets patients’ expectations.
Method
A questionnaire-based cross-sectional survey was administered pre- and post-operatively. Patients were classified according to typology, namely metamorphosizers - patients with high expectation of psychological and physical changes, evolvers - opposite of metamorphosizers, pragmatists - low expectation of psychological and high expectation of physical changes, and shedders - opposite of pragmatists. A chi-square test was used to examine whether orthognathic surgery met patients’ expectations.
Results
A total of 27 patients consisting of 19 pre-operative and 8 post-operative completed the survey over an 11-month study period (females = 11; males = 16; mean age= 22.5 years; range = 17-52). Typologically, metamorphosizers dominated, 48%, followed by shedders, 30%, evolvers, 13% and pragmatists, 9%. This indicates that most patients, 78% (metamorphosizers and shedders) had high expectations of psychological change pre-operatively [X2 (2, N = 90) = 43.9, p < .0001)] and perceptions of psychological change post-operatively [X2 (2, N = 90) = 48.8, p < .0001)].
Conclusions
Most patients in this study anticipated and perceived psychological changes after orthognathic surgery. Understanding patient typology may help the orthognathic surgeon understand, address and improve post-operative psychological outcomes in their patients.

Abstract
Purpose Ocular surface mucins and glycocalyx are critical for providing ocular hydration as well lubrication and repelling pathogens or allergens. Elevated levels of tear proinflammatory cytokines in dry eye may have detrimental effect on mucins and glycocalyx. The present study tested the effect of proinflammatory cytokines IL-6, TNF-α, and IFN-γ on membrane-tethered mucins expression, glycocalyx, and viability of ocular surface epithelial cells. Methods Stratified cultures of human corneal and conjunctival epithelial cells were exposed to different concentrations of IL-6, TNF-α, and IFN-γ for 24 hours. The mucins gene and protein expressions were quantified by real-time polymerase chain reaction (PCR) and enzyme-linked immunosorbent assay (ELISA). The glycocalyx was imaged using confocal microscopy after staining with Alexa 488-conjugated wheat germ agglutinin lectin. Apoptotic and necrotic cell death was quantified using flow cytometry. Results IL-6, TNF-α, and IFN-γ treatment resulted in a significant increase in mucins (MUC)1 and MUC4 gene and protein expression in human corneal epithelial cells but caused no significant changes in the levels of these mucins in conjunctival epithelial cells. Further, these cytokines decreased MUC16 expression in both corneal and conjunctival epithelial cells. Moreover, no notable change in glycocalyx or apoptotic cell death in corneal and conjunctival epithelial cells was noted with any of the tested cytokines, but IL-6 and TNF-α exposure increased necrotic cell death in corneal and conjunctival epithelial cells, respectively. Conclusions Our results demonstrate that proinflammatory cytokines have differential effects on human corneal and conjunctival epithelial cell mucins expression, but do not cause any damage to ocular surface epithelial cell glycocalyx.

Mortality from esophagectomy for esophageal cancer across low, middle, and high-income countries: An international cohort study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2021; 47:1481-1488. [PMID: 33451919 DOI: 10.1016/j.ejso.2020.12.006] [Citation(s) in RCA: 16] [Impact Index Per Article: 5.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 12/09/2020] [Indexed: 02/08/2023]
Abstract
BACKGROUND No evidence currently exists characterising global outcomes following major cancer surgery, including esophageal cancer. Therefore, this study aimed to characterise impact of high income countries (HIC) versus low and middle income countries (LMIC) on the outcomes following esophagectomy for esophageal cancer. METHOD This international multi-center prospective study across 137 hospitals in 41 countries included patients who underwent an esophagectomy for esophageal cancer, with 90-day follow-up. The main explanatory variable was country income, defined according to the World Bank Data classification. The primary outcome was 90-day postoperative mortality, and secondary outcomes were composite leaks (anastomotic leak or conduit necrosis) and major complications (Clavien-Dindo Grade III - V). Multivariable generalized estimating equation models were used to produce adjusted odds ratios (ORs) and 95% confidence intervals (CI95%). RESULTS Between April 2018 to December 2018, 2247 patients were included. Patients from HIC were more significantly older, with higher ASA grade, and more advanced tumors. Patients from LMIC had almost three-fold increase in 90-day mortality, compared to HIC (9.4% vs 3.7%, p < 0.001). On adjusted analysis, LMIC were independently associated with higher 90-day mortality (OR: 2.31, CI95%: 1.17-4.55, p = 0.015). However, LMIC were not independently associated with higher rates of anastomotic leaks (OR: 1.06, CI95%: 0.57-1.99, p = 0.9) or major complications (OR: 0.85, CI95%: 0.54-1.32, p = 0.5), compared to HIC. CONCLUSION Resections in LMIC were independently associated with higher 90-day postoperative mortality, likely reflecting a failure to rescue of these patients following esophagectomy, despite similar composite anastomotic leaks and major complication rates to HIC. These findings warrant further research, to identify potential issues and solutions to improve global outcomes following esophagectomy for cancer.

Abstract
Background:B-lymphocyte stimulator (BLyS) is increased in primary Sjögren’s syndrome (pSS) and plays a role in the B-cell hyperactivity thought to contribute to pSS. Belimumab (BEL, anti-BLyS) and rituximab (RTX, anti-CD20) target B cells through distinct and potentially complementary mechanisms.Objectives:To evaluate the safety and efficacy of subcutaneous (SC) BEL/intravenous (IV) RTX combination (BEL/RTX) in patients with pSS.Methods:This Phase 2, double-blind study (GSK Study 201842; NCT02631538) randomised 86 adults with active pSS to 4 treatment arms stratified for baseline EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI) scores 5-12 or >12: placebo (PBO; N=13), BEL/RTX (N=24; BEL 200 mg SC weekly to Week [Wk] 24 followed by weekly PBO SC to Wk 52 + RTX 1000 mg IV, Wk 8 + 10), BEL monotherapy (N=24; BEL 200 mg SC weekly to Wk 52) or RTX monotherapy (N=25; RTX 1000 mg IV, Wk 8 + 10). Follow-up was at Wk 68. Safety to Wk 68 was the primary endpoint (safety population; patients received ≥1 dose of study treatment). Secondary/other endpoints (completer population; patients completed treatment and follow-up phase) were ESSDAI score, stimulated salivary flow, CD20+ B-cell count within salivary gland biopsies, patient-reported oral dryness, and EULAR Sjögren’s Syndrome Patient Reported Index (ESSPRI) score.Results:Baseline demographics and disease characteristics were similar among arms. Adverse events (AEs) were balanced across arms. Serious AEs were infrequent but occurred only in active treatment arms (Table). No unexpected safety issues were identified with BEL/RTX relative to BEL or RTX. Treatment phase and follow-up were completed by 60/86 patients. ESSDAI reductions with BEL/RTX were numerically greater over time than PBO, with greatest difference at Wk 68 (Table), but were not differentiated from monotherapy. Stimulated salivary flow showed a trend favouring BEL/RTX vs PBO over later time points (Table). In contrast with PBO, BEL, and RTX, salivary gland biopsies from BEL/RTX showed almost complete B-cell depletion (Wk 24). There was no clear evidence for a positive effect of BEL/RTX on patient-reported oral dryness or ESSPRI score.Table 1.Key safety endpoints and selected efficacy endpointsAEs – safety populationPBO(N=13)BEL/RTX (N=24)BEL(N=24)RTX(N=25)AEs, n (%)13 (100)24 (100)23 (96)24 (96)Drug-related AEs, n (%)10 (77)17 (71)16 (67)14 (56)AEs leading to discontinuation/withdrawal, n (%)1 (8)5 (21)3 (13)5 (20)SAEs, n (%)03 (13)2 (8)4 (16)Number of SAEs0427Deaths, n (%)01 (4)*00Infections and Infestations, n (%)†11 (85)19 (79)21 (88)18 (72)Efficacy – completer populationPBO (N=8)BEL/RTX (N=17)BEL (N=19)RTX (N=16)ESSDAI change, LS mean (SE) from BL over time‡Wk 12-2.00 (1.449)-4.85 (0.996)-3.87 (0.949)-4.22 (1.048)§Wk 24-2.87 (1.324)-5.32 (0.911)-3.87 (0.869)-5.25 (0.940)Wk 52-2.87 (1.294)-5.67 (0.890)-4.76 (0.850)-4.32 (0.919)Wk 68-1.75 (1.400)-5.73 (0.962)-3.87 (0.918)-4.38 (0.994)Stimulated salivary flow (ml/min), mean (SD)BL0.47 (0.247)0.71 (0.629)0.43 (0.329)0.62 (0.621)Wk 120.49 (0.205)0.75 (0.834)0.49 (0.373)0.58 (0.527)Wk 240.55 (0.305)0.78 (0.790)0.45 (0.411)0.72 (0.890)Wk 520.53 (0.378)1.00 (1.146)0.58 (0.608)0.69 (0.781)Wk 680.36 (0.163)0.88 (0.817)0.52 (0.450)0.73 (0.785)§*Aspiration (n=1); not considered related to treatment; patient died of food aspiration; †System organ class with the highest percent of AEs; ‡Analysis was performed using mixed model repeated measures; §n=15.BL, baseline; LS, Least square; SAEs, serious AEs; SD, standard deviation; SE, standard errorConclusion:No unexpected safety issues were identified with BEL/RTX relative to BEL or RTX.

Comparison of short-term outcomes from the International Oesophago-Gastric Anastomosis Audit (OGAA), the Esophagectomy Complications Consensus Group (ECCG), and the Dutch Upper Gastrointestinal Cancer Audit (DUCA). BJS Open 2021; 5:zrab010.

Abstract
BACKGROUND The Esophagectomy Complications Consensus Group (ECCG) and the Dutch Upper Gastrointestinal Cancer Audit (DUCA) have set standards in reporting outcomes after oesophagectomy. Reporting outcomes from selected high-volume centres or centralized national cancer programmes may not, however, be reflective of the true global prevalence of complications. This study aimed to compare complication rates after oesophagectomy from these existing sources with those of an unselected international cohort from the Oesophago-Gastric Anastomosis Audit (OGAA). METHODS The OGAA was a prospective multicentre cohort study coordinated by the West Midlands Research Collaborative, and included patients undergoing oesophagectomy for oesophageal cancer between April and December 2018, with 90 days of follow-up. RESULTS The OGAA study included 2247 oesophagectomies across 137 hospitals in 41 countries. Comparisons with the ECCG and DUCA found differences in baseline demographics between the three cohorts, including age, ASA grade, and rates of chronic pulmonary disease. The OGAA had the lowest rates of neoadjuvant treatment (OGAA 75.1 per cent, ECCG 78.9 per cent, DUCA 93.5 per cent; P < 0.001). DUCA exhibited the highest rates of minimally invasive surgery (OGAA 57.2 per cent, ECCG 47.9 per cent, DUCA 85.8 per cent; P < 0.001). Overall complication rates were similar in the three cohorts (OGAA 63.6 per cent, ECCG 59.0 per cent, DUCA 62.2 per cent), with no statistically significant difference in Clavien-Dindo grades (P = 0.752). However, a significant difference in 30-day mortality was observed, with DUCA reporting the lowest rate (OGAA 3.2 per cent, ECCG 2.4 per cent, DUCA 1.7 per cent; P = 0.013). CONCLUSION Despite differences in rates of co-morbidities, oncological treatment strategies, and access to minimal-access surgery, overall complication rates were similar in the three cohorts.

Abstract
PURPOSE Two subgroups of fecal incontinence (FI) are described in literature and used in clinical practice. However, the pertinence of this classification of FI is still unknown as there are no clear established guidelines. To a better understanding, we performed a systematic review to characterize the different types of FI (active, passive, or mixed) on the basis of clinical presentation and complementary explorations. METHODS This systematic literature review was performed in reference to recommendations for systematic review using PRISMA guidelines without date restriction, until May 2020. This systematic review was performed without temporal limitation using MEDLINE-PubMed, Cochrane Library, and Google Scholar databases. RESULTS Six hundred nine unique citations were identified from all the databases combined. Of those, 21 studies met the inclusion criteria, with 8 retrospective observational studies and 13 prospective observational studies. There was a lack of homogeneity in definitions of passive and urge (active) FI among studies. Prevalence of passive and urge FI was respectively of 4.0-5.0 and 15.0-35.0%. Clinical characteristics, physical examination, and endoanal imaging were not evaluated in most studies. In anorectal manometry, maximal squeeze pressure was higher in passive FI subgroup in most studies and results regarding maximal resting pressure remain discordant. There seemed to be no difference regarding first sensation volume and maximal tolerable volume among subgroups. A few studies evaluated pudendal terminal nerve motor latency with no difference among subgroups. CONCLUSION There is a lack of well-conducted prospective studies comparing the different subtypes of FI with validated definitions in both clinical and paraclinical examinations.

Circadian influence on the microbiome improves heart failure outcomes. J Mol Cell Cardiol 2020; 149:54-72.

Abstract
Myocardial infarction (MI) leading to heart failure (HF) is a major cause of death worldwide. Previous studies revealed that the circadian system markedly impacts cardiac repair post-MI, and that light is an important environmental factor modulating the circadian influence over healing. Recent studies suggest that gut physiology also affects the circadian system, but how it contributes to cardiac repair post-MI and in HF is not well understood. To address this question, we first used a murine coronary artery ligation MI model to reveal that an intact gut microbiome is important for cardiac repair. Specifically, gut microbiome disruption impairs normal inflammatory responses in infarcted myocardium, elevates adverse cardiac gene biomarkers, and leads to worse HF outcomes. Conversely, reconstituting the microbiome post-MI in mice with prior gut microbiome disruption improves healing, consistent with the notion that normal gut physiology contributes to cardiac repair. To investigate a role for the circadian system, we initially utilized circadian mutant Clock∆19/∆19 mice, revealing that a functional circadian mechanism is necessary for gut microbiome benefits on post-MI cardiac repair and HF. Finally, we demonstrate that circadian-mediated gut responses that benefit cardiac repair can be conferred by time-restricted feeding, as wake time feeding of MI mice improves HF outcomes, but these benefits are not observed in MI mice fed during their sleep time. In summary, gut physiology is important for cardiac repair, and the circadian system influences the beneficial gut responses to improve post-MI and HF outcomes.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
The aim of this paper was to find out whether orthognathic surgery affects facial recognition at automated border controls in airports, and whether we should recommend that patients update their photographic identification postoperatively. We collected data on all 82 patients who had orthognathic surgery between August 2013 and June 2017. They were contacted by telephone and asked about any difficulties they had encountered when passing through automated or human-operated border controls or when using other forms of photographic identification such as driving licences. All questions were asked with reference to experiences before the operation. A total of 50 patients responded, of which 35 had travelled by aeroplane since their operations. Six of them had had problems passing through passport control (two human-operated and four automated) but after additional security checks had successfully continued their journeys. Four had had bimaxillary surgery, one had had maxillary advancement, and one mandibular advancement. Orthognathic surgery does affect identification at border controls, and most of our patients had had difficulties at automated checks because of the differences between the biometric data within the e-passport chip and the live biometric that was scanned. These findings will enable us to improve the information we give to our patients before operation, but further studies are required to increase the sample size and improve reliability.

Changes in glycaemic control, blood pressure and lipids 5 years following laparoscopic adjustable gastric banding combined with medical care in patients with type 2 diabetes: a longitudinal analysis. Clin Obes 2018; 8:151-158.

Abstract
The long-term outcomes of weight loss maintenance induced by laparoscopic adjustable gastric band (LAGB) followed by multidisciplinary medical care in patients with type 2 diabetes mellitus (T2DM) (beyond 3 years) are scarcely reported. Study aims were to determine the longer term metabolic outcomes following LAGB combined with medical care in patients with T2DM. This is a longitudinal analysis of 200 adults with T2DM who had LAGB between 2003 and 2008 and were followed up till 2013 at a single bariatric unit in a tertiary UK centre. A total of 200 patients (age 47 ± 9.7 years; body mass index [BMI] 52.8 ± 9.2 kg m-2 ; glycosylated haemoglobin (HbA1c) 7.9 ± 1.9% [62.8 mmol mol-1 ]; women, n = 123 [61.5%]; insulin treatment, n = 71 [35.5%]) were included. The mean follow-up was 62.0 ± 13.0 months (range 18-84 months). There were significant reductions in body weight (-24.4 ± 12.3% [38 ± 22.7 kg]), HbA1c (-1.4 ± 2.0%), systolic blood pressure [BP] (-11.7 ± 23.5 mmHg), total cholesterol and triglyceride levels. The proportion of patients requiring insulin reduced from 36.2% to 12.3%. The overall band complication rate was 21% (21 patients). LAGB when combined with multidisciplinary medical care significantly improved metabolic outcomes in patients with T2DM independent of diabetes duration, and baseline BMI over 5 years. Diabetes duration and baseline BMI did not predict changes in glycaemic control, BP or lipids following LAGB.

Cytoreductive surgery with intraperitoneal chemotherapy in the management of peritoneal surface malignancy: a pharmacist's perspective. Eur J Hosp Pharm 2016; 23:233-238.

Abstract
Objectives To explore the use of intraperitoneal chemotherapy in conjunction with cytoreductive surgery for the treatment of peritoneal surface malignancy and highlight the challenges this provides for the hospital pharmacist. Methods A literature search for relevant articles was performed using MEDLINE, PubMed and Cochrane databases. The following keywords and phrases were used: 'hyperthermic intraperitoneal chemotherapy', 'early postoperative intraperitoneal chemotherapy', 'carrier solutions' and 'cytoreductive surgery'. Local experience was also shared, referencing national guidelines and published literature. Results The rationale behind intraperitoneal chemotherapy is to directly administer drugs into the peritoneal cavity and achieve exposure of higher concentrations of cytotoxic agents to tumour nodules within the abdomen and on peritoneal surfaces for a prolonged period of time, without significant systemic toxicity. This has been widely demonstrated in intraoperative and early postoperative settings. Hydrophilic chemotherapy drugs with high molecular weights and permeable to the peritoneum, but slow plasma clearance create high concentrations of the drug in the peritoneal cavity, with lower systemic circulation. Commonly used drugs include mitomycin C, oxaliplatin, cisplatin, doxorubicin and 5-fluorouracil. Newer drugs such as the taxanes and bevacizumab have also shown promise. Heat increases drug penetration into body tissues and destroys tumour cells directly by causing damage to cells that have inherently faulty heat regulation pathways and also increases the cytotoxic effect of selected chemotherapeutic agents. Optimal temperature for hyperthermic intraperitoneal drug administration is between 41 and 43°C in a carrier solution that is compatible with the drug chosen. For early postoperative intraperitoneal chemotherapy high molecular weight starch carrier solutions prolong intraperitoneal dwell time and exposure of drug to tumour cells. Drugs are administered intraoperatively with the abdomen open or closed for between 30 and 120 min depending on the drug chosen and local protocols. Drug doses are traditionally calculated using body surface area. Toxicity such as neutropenia is encountered far less than with systemic chemotherapy. Conclusions This paper discusses the rationale for intraperitoneal drug administration following cytoreductive surgery and describes appropriate drug selection, methods of drug delivery and potential challenges in the use of the intraperitoneal route. It provides evidence and practical guidance for hospital pharmacists who may be involved in the surgical management of peritoneal malignancy particularly in dose calculation, preparation and administration of intraperitoneal chemotherapy.

Abstract
Rapid prototyping of bone tissue engineering constructs often utilizes elevated temperatures, organic solvents and/or UV light for materials processing. These harsh conditions may prevent the incorporation of cells and therapeutic proteins in the fabrication processes. Here we developed a method for using bioprinting to produce constructs from a thermoresponsive microparticulate material based on poly(lactic-co-glycolic acid) at ambient conditions. These constructs could be engineered with yield stresses of up to 1.22 MPa and Young's moduli of up to 57.3 MPa which are within the range of properties of human cancellous bone. Further study showed that protein-releasing microspheres could be incorporated into the bioprinted constructs. The release of the model protein lysozyme from bioprinted constructs was sustainted for a period of 15 days and a high degree of protein activity could be measured up to day 9. This work suggests that bioprinting is a viable route to the production of mechanically strong constructs for bone repair under mild conditions which allow the inclusion of viable cells and active proteins.

Abstract
Evidence-based therapeutic goals have been developed by European and North American experts in the field of Gaucher disease (GD, lysosomal acid beta glucosidase deficiency, OMIM 230 800) in an attempt to reverse the entire disease phenotype, improve quality of life and prevent life-threatening complications. Patients with GD usually have maximal clinical benefit when enzyme replacement treatment (ERT) efficiency is administered at the optimal time i.e. generally during the asymptomatic phase of the disease. Currently, imiglucerase is the standard of care for type 1 GD due to its high efficiency at improving bleeding tendencies, anemia, reversing heptosplenomegaly and part of skeletal damages and eliminating bone crises. ERT has also demonstrated a remarkable safety profile with tolerability at 3 years greater than 99%. Treatment of GD is a lifelong treatment that patients should not interrupt without a careful monitoring of the disease evolution.

Abstract
The rate of laser ablation at irradiances of approximately 2 x 10{14} W cm{-2} of solid iron has been measured using the transmission of a neonlike zinc x-ray laser at 21.2 nm through thin iron targets. Ablated iron becomes transparent to the x-ray laser flux, enabling the thickness of unablated material and hence the rate of ablation to be measured from time resolved x-ray laser transmission.

Abstract
The temporal evolution of the opacity of an iron plasma at high temperature (30-350 eV) and high density (0.001-0.2 g cm-3) has been measured using a nickel-like silver x-ray laser at 13.9 nm. The hot dense iron plasma was created in a thin (50 nm) iron layer buried 80 nm below the surface in a plastic target that was heated using a separate 80 ps pulse of 6-9 J, focused to a 100 microm diameter spot. The experimental opacities are compared with opacities evaluated from plasma conditions predicted using a fluid and atomic physics code.

Abstract
The Gaucher phenotype is very complex and it cannot be simply evaluated on the basis of blood counts or splenomegaly, but by the analysis of all disease compartments. To establish the diagnosis of Gaucher disease, biochemical assay of glucocerebrosidase activity is the most reliable method. However, it can be supplemented by molecular diagnosis, which may be helpful to predict the severity and the rate of progression of clinical manifestations. The genotype-phenotype correlations are very complex with a high inter-individual variability in the severity of clinical manifestations within a same genotype. Genetic modifiers may play an important role in determining the eventual Gaucher phenotype. Despite of some devastating complications, which can arise with advancing age, Gaucher disease worsen progressively in the majority of patients homozygous for the N370S mutation. The analysis of the data of the International Collaborative Gaucher Group registry should provide a better understanding of the natural history of the Gaucher disease.

Patients with Gaucher disease will benefit by maximum enzyme replacement treatment (ERT) efficiency if it is given at the optimal time i.e. generally during the asymptomatic phase of the disease. Currently, Cerezyme is the standard of care for all severities of type 1 Gaucher disease due to its high efficiency at ameliorating bleeding tendencies, reversing organomegaly and part of skeletal damages and eliminating bone crises. ERT has also demonstrated a remarkable safety profile with tolerability at 3 years greater than 99%. Treatment of Gaucher disease is a long-life treatment that the patient should not interrupt without a careful monitoring of the disease evolution.
