Clinical Characteristics and Outcomes of Fungal Keratitis in the United Kingdom 2011–2020: A 10-Year Study

Fungal keratitis (FK) is a serious ocular infection that often poses significant diagnostic and therapeutic dilemmas. This study aimed to examine the causes, clinical characteristics, outcomes, and prognostic factors of FK in the UK. All culture-positive and culture-negative presumed FK (with complete data) that presented to Queen’s Medical Centre, Nottingham, and the Queen Victoria Hospital, East Grinstead, between 2011 and 2020 were included. We included 117 patients (n = 117 eyes) with FK in this study. The mean age was 59.0 ± 19.6 years (range, 4–92 years) and 51.3% of patients were female. Fifty-three fungal isolates were identified from 52 (44.4%) culture-positive cases, with Candida spp. (33, 62.3%), Fusarium spp. (9, 17.0%), and Aspergillus spp. (5, 9.4%) being the most common organisms. Ocular surface disease (60, 51.3%), prior corneal surgery (44, 37.6%), and systemic immunosuppression (42, 35.9%) were the three most common risk factors. Hospitalisation for intensive treatment was required for 95 (81.2%) patients, with a duration of 18.9 ± 16.3 days. Sixty-six (56.4%) patients required additional surgical interventions for eradicating the infection. Emergency therapeutic/tectonic keratoplasty was performed in 29 (24.8%) cases, though 13 (44.8%) of them failed at final follow-up. The final corrected-distance-visual-acuity (CDVA) was 1.67 ± 1.08 logMAR. Multivariable logistic regression analyses demonstrated increased age, large infiltrate size (>3 mm), and poor presenting CDVA (60 days of healing time or occurrence of corneal perforation requiring emergency keratoplasty; all p < 0.05). In conclusion, FK represents a difficult-to-treat ocular infection that often results in poor visual outcomes, with a high need for surgical interventions. Innovative treatment strategies are urgently required to tackle this unmet need

Burnout among surgeons before and during the SARS-CoV-2 pandemic: an international survey

Background: SARS-CoV-2 pandemic has had many significant impacts within the surgical realm, and surgeons have been obligated to reconsider almost every aspect of daily clinical practice. Methods: This is a cross-sectional study reported in compliance with the CHERRIES guidelines and conducted through an online platform from June 14th to July 15th, 2020. The primary outcome was the burden of burnout during the pandemic indicated by the validated Shirom-Melamed Burnout Measure. Results: Nine hundred fifty-four surgeons completed the survey. The median length of practice was 10&nbsp;years; 78.2% included were male with a median age of 37&nbsp;years old, 39.5% were consultants, 68.9% were general surgeons, and 55.7% were affiliated with an academic institution. Overall, there was a significant increase in the mean burnout score during the pandemic; longer years of practice and older age were significantly associated with less burnout. There were significant reductions in the median number of outpatient visits, operated cases, on-call hours, emergency visits, and research work, so, 48.2% of respondents felt that the training resources were insufficient. The majority (81.3%) of respondents reported that their hospitals were included in the management of COVID-19, 66.5% felt their roles had been minimized; 41% were asked to assist in non-surgical medical practices, and 37.6% of respondents were included in COVID-19 management. Conclusions: There was a significant burnout among trainees. Almost all aspects of clinical and research activities were affected with a significant reduction in the volume of research, outpatient clinic visits, surgical procedures, on-call hours, and emergency cases hindering the training. Trial registration: The study was registered on clicaltrials.gov "NCT04433286" on 16/06/2020

Epidemiology and survival of colon cancer among Egyptians: a retrospective study

Introduction: Colorectal cancer is the 4th commonest cancer in the world. Studies had shown different tumor behavior depending on the site, pathology and stage. However the characters of Egyptian colon cancer patients are not well addressed. Method: Computerized registry of a tertiary cancer hospital in Egypt was searched for colon cancer cases. Demographic, pathologic and treatment data were collected and analyzed using SPSS program. Results: About 360 colon cancer patients attended our center in the last 12 years. Tumor characters showed great diverse from that of developed countries, with especially different prognosis and survival. Conclusion: Egyptians have unique tumor characters and behavior, and different compliance with treatment regimens. Multicenter prospective studies, as well as evolving Egyptian treatment guidelines are needed to address this. Resumo: Introdução: Câncer colorretal é a quarta neoplasia mais comum a nível mundial. Estudos demonstraram diferentes comportamentos do tumor, dependendo do local, da patologia e do estágio. Contudo, ainda não estão devidamente definidas as características dos pacientes egípcios com câncer de cólon. Métodos: Foi realizada pesquisa no registro computadorizado de um hospital terciário para pacientes com câncer, à busca de casos de câncer de cólon. Foi feita coleta de dados demográficos, patológicos e terapêuticos. Tais dados foram então submetidos à análise com o programa SPSS. Resultados: Nos últimos 12 anos, cerca de 360 pacientes portadores de câncer de cólon foram atendidos em nosso Centro. As características dos tumores demonstraram grandes diferenças em comparação com os achados de países desenvolvidos e, em especial, com relação ao prognóstico e à sobrevida. Conclusão: Os egípcios exibem características e comportamentos singulares com relação aos tumores, além de diferentes graus de cooperação com os regimes terapêuticos. Para que tais aspectos sejam sanados, há necessidade de mais estudos prospectivos multicêntricos, bem como de um aprimoramento das diretrizes terapêuticas para os egípcios.

Association between HCV induced mixed cryoglobulinemia and pulmonary affection: The role of TNF-alpha in the pathogenesis of pulmonary changes

Background and aim of the work: Chronic hepatitis C virus (HCV) infection is associated with both pulmonary involvement and cryoglobulinemia. Therefore, this study was designed to investigate the relationship between pulmonary involvement and mixed cryoglobulinemia in chronic HCV infected patients and to investigate the role of TNF-alpha in the pathogenesis of pulmonary changes. Subjects and methods: After hospital ethics committee approval and formal patient consent were obtained, 100 patients with compensated hepatitis C virus infection as confirmed by PCR were recruited in this cross sectional study. Their demographic and laboratory data, abdominal ultrasound findings, pulmonary function tests (spirometry), arterial blood gas (ABG) parameters, TNF-alpha levels, and data from high-resolution chest CT were collected and analyzed using SPSS version 16, and a serum cryoglobulin assay was performed in all of the studied patients. Results: The prevalence of mixed cryoglobulinemia was 61.7% in the studied HCV patients. Pulmonary symptoms were observed in more than half of these patients. The most common complaint among the symptomatic patients was dyspnea (51.7%), followed by cough (43.3%). Oxygen saturation (Spo2 and Sao2%), and FEV1 and FVC levels, were significantly decreased in the cryoglobulin positive patients compared to the cryoglobulin negative patients. A statistically significant correlation was found between the presence of cryoglobulins and FEV1 level, FVC level, serum albumin level, viremia level, thrombocytopenia and arterial blood gas parameters. No correlation was found between cryoglobulinemia and TNF-alpha level. Conclusions: The results of this study suggest that pulmonary involvement is common in patients with chronic HCV infection and mixed cryoglobulinemia. Cryoglobulinemia may lead to pulmonary involvement through vascular and interstitial deposition of cryoglobulins, which results in impaired gas exchange and airway affection
