CLCA1 is Poorly Expressed in Stomach Adenocarcinoma and Correlates with Immune Infiltration / CLCA1 se Expresa Deficientemente en el Adenocarcinoma de Estómago y se Correlaciona con la Infiltración Inmune

SUMMARY: Calcium-activated chloride channel regulator 1 (CLCA1) is associated with cancer progression. The expression and immunologic function of CLCA1 in stomach adenocarcinoma (STAD) remain unclear. In this investigation, the expression of CLCA1 in STAD tissues and its involvement in the progression and immune response of STAD were examined using databases such as cBioPortal, TISIDB, and UALCAN. In order to validate the expression level of CLCA1 protein in gastric adenocarcinoma, thirty clinical tissue specimens were gathered for immunohistochemical staining. The findings indicated a downregulation of CLCA1 in STAD patients, which was correlated with race, age, cancer grade, Helicobacter pylori infection, and molecular subtype. Through the examination of survival analysis, it was identified that diminished levels of CLCA1 within gastric cancer cases were linked to decreased periods of post-progression survival (PPS), overall survival (OS), and first progression (FP) (P<0.05). The CLCA1 mutation rate was lower in STAD, but the survival rate was higher in the variant group. The correlation between the expression level of CLCA1 and the levels of immune infiltrating cells in STAD, as well as the immune activating molecules, immunosuppressive molecules, MHC molecules, chemokines, and their receptor molecules, was observed. Gene enrichment analysis revealed that CLCA1 may be involved in STAD progression through systemic lupus erythematosus (SLE), proteasome, cell cycle, pancreatic secretion, and PPAR signaling pathways. In summary, CLCA1 is anticipated to function as a prognostic marker for patients with STAD and is linked to the immunization of STAD.

El regulador 1 del canal de cloruro activado por calcio (CLCA1) está asociado con la progresión del cáncer. La expresión y la función inmunológica de CLCA1 en el adenocarcinoma de estómago (STAD) aún no están claras. En esta investigación, se examinó la expresión de CLCA1 en tejidos STAD y su participación en la progresión y respuesta inmune de STAD utilizando bases de datos como cBioPortal, TISIDB y UALCAN. Para validar el nivel de expresión de la proteína CLCA1 en el adenocarcinoma gástrico, se recolectaron treinta muestras de tejido clínico para tinción inmunohistoquímica. Los hallazgos indicaron una regulación negativa de CLCA1 en pacientes con STAD, que se correlacionó con la raza, la edad, el grado del cáncer, la infección por Helicobacter pylori y el subtipo molecular. Mediante el examen del análisis de supervivencia, se identificó que los niveles reducidos de CLCA1 en los casos de cáncer gástrico estaban relacionados con períodos reducidos de supervivencia posterior a la progresión (PPS), supervivencia general (OS) y primera progresión (FP) (P <0,05). La tasa de mutación CLCA1 fue menor en STAD, pero la tasa de supervivencia fue mayor en el grupo variante. Se observó la correlación entre el nivel de expresión de CLCA1 y los niveles de células inmunes infiltrantes en STAD, así como las moléculas activadoras inmunes, moléculas inmunosupresoras, moléculas MHC, quimiocinas y sus moléculas receptoras. El análisis de enriquecimiento genético reveló que CLCA1 puede estar involucrado en la progresión de STAD a través del lupus eritematoso sistémico (LES), el proteasoma, el ciclo celular, la secreción pancreática y las vías de señalización de PPAR. En resumen, se prevé que CLCA1 funcione como un marcador de pronóstico para pacientes con STAD y está vinculado a la inmunización de STAD.

Testes de Triagem Prevendo Metástase de Câncer na Etiologia do Derrame Pericárdico: HALP Score e PNI / Screening Tests Predicting Cancer Metastasis in the Etiology of Pericardial Effusion: HALP Score and PNI

Resumo Fundamento: A triagem do câncer é absolutamente necessária em pacientes com derrame pericárdico, pois o câncer é uma das doenças mais graves em sua etiologia. Estudos anteriores indicaram que o índice de inflamação imunológica sistêmica (IIS), o índice prognóstico nutricional (PNI) e o escore de hemoglobina, albumina, linfócitos e plaquetas (HALP) podem ser escores relacionados ao câncer. Objetivos: Este estudo foi iniciado considerando que esses sistemas de pontuação poderiam prever o câncer na etiologia de pacientes com derrame pericárdico. Métodos: Os pacientes submetidos à pericardiocentese entre 2006 e 2022 foram analisados retrospectivamente. A pericardiocentese foi realizada em um total de 283 pacientes com derrame pericárdico ou tamponamento cardíaco de moderado a grande no período especificado. Os índices de HALP, PNI e IIS foram calculados do sangue venoso periférico retirado antes do procedimento de pericardiocentese. O nível de significância estatística foi aceito em p<0,05. Resultados: O escore HALP foi de 0,173 (0,125-0,175) em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi de 0,32 (0,20-0,49; p<0,001). O escore de PNI foi de 33,1±5,6 em pacientes com câncer. Detectou-se que em pacientes não oncológicos o escore foi 39,8±4,8 (p<0,001). Conclusão: Os escores HALP e PNI são testes de triagem de câncer fáceis e rápidos que podem prever metástases de câncer na etiologia de pacientes com derrame pericárdico.

Abstract Background: Cancer screening is absolutely necessary in patients with pericardial effusion, given that cancer is one of the most serious diseases in the etiology of pericardial effusion. In previous studies, it was stated that the systemic immune-inflammation index (SII); the prognostic nutrition index (PNI); and the hemoglobin, albumin, lymphocyte, platelet (HALP) score can produce scores related to cancer. Objectives: This study began considering that these scoring systems could predict cancer in the etiology of patients with pericardial effusion. Methods: This study produced a retrospective analysis of patients who underwent pericardiocentesis between 2006 and 2022. Pericardiocentesis was performed in a total of 283 patients with moderate-to-large pericardial effusion or pericardial tamponade within the specified period. HALP, PNI, and SII scores were calculated according to the peripheral venous blood taken before the pericardiocentesis procedure. The statistical significance level was set at p<0.05. Results: The HALP score proved to be 0.173 (0.125-0.175) in cancer patients and 0.32 (0.20-0.49) in non-cancer patients (p<0.001). The PNI score proved to be 33.1±5.6 in cancer patients and 39.8±4.8 in non-cancer patients (p<0.001). Conclusion: The HALP score and PNI proved to be easy and fast cancer screening tests that can predict cancer metastasis in the etiology of patients with pericardial effusion.

Prognostic awareness and prognostic information preferences among advanced cancer patients in Kenya

Background: Cancer is the third leading cause of death in Kenya. Yet, little is known about prognostic awareness and preferences for prognostic information. Aim: To assess the prevalence of prognostic awareness and preference for prognostic information among advanced cancer patients in Kenya. Setting: Outpatient medical oncology and palliative care clinics and inpatient medical and surgical wards of Moi Teaching and Referral Hospital (MTRH) in Eldoret, Kenya. Methods: The authors surveyed 207 adults with advanced solid cancers. The survey comprised validated measures developed for a multi-site study of end-of-life care in advanced cancer patients. Outcome variables included prognostic awareness and preference for prognostic information. Results: More than one-third of participants (36%) were unaware of their prognosis and most (67%) preferred not to receive prognostic information. Increased age (OR = 1.04, 95% CI: 1.02, 1.07) and education level (OR: 1.18, CI: 1.08, 1.30) were associated with a higher likelihood of preference to receive prognostic information, while increased symptom burden (OR= 0.94, CI: 0.90, 0.99) and higher perceived household income levels (lower-middle vs low: OR= 0.19; CI: 0.09, 0.44; and upper middle- or high vs low: OR= 0.22, CI: 0.09, 0.56) were associated with lower odds of preferring prognostic information. Conclusion: Results reveal low levels of prognostic awareness and little interest in receiving prognostic information among advanced cancer patients in Kenya. Contribution: Given the important role of prognostic awareness in providing patient-centred care, efforts to educate patients in Kenya on the value of this information should be a priority, especially among younger patients.

Prognostic Value and Immune Infiltration of Anoikis-related LncRNAs in Lung Adenocarcinoma / 肿瘤防治研究

Objective To explore the prognostic value and immune infiltration landscape of anoikis-related long noncoding RNAs (arlncRNAs) in lung adenocarcinoma. Methods RNA-seq and clinical data of lung adenocarcinoma were downloaded from the TCGA database, and anoikis-related genes were obtained from the GeneCards and Harmonizome databases. Coexpression, differential, and WGCNA analyses were performed to screen differentially expressed arlncRNAs closely related to the occurrence of lung adenocarcinoma. A prognostic risk model was then constructed based on the arlncRNAs, and its predictive efficacy was further validated. Finally, consensus clustering was used to identify the molecular subtypes associated with anoikis in lung adenocarcinoma. Results Seven prognostic arlncRNAs were identified, and the prognostic risk models established based on them had AUC values of ROC curves greater than 0.7. Survival and immune infiltration analyses revealed that low-risk patients had high overall survival and immune infiltration, implying that they experienced good immune treatment effects. Drug sensitivity analysis showed that the high-risk patients were more sensitive to commonly used chemotherapeutic agents than the low-risk patients. According to the expression of model genes, subtypes C1 and C2 were identified through consensus clustering, and C1 showed a good prognosis. Conclusion The prognostic risk model based on the seven arlncRNAs can effectively predict the prognosis of lung adenocarcinoma patients. The results of immune-related and drug sensitivity analyses provide a reference for the precise individualized treatment of patients with lung adenocarcinoma.

Application status of risk assessment models for periodontal disease / 口腔疾病防治

@#Risk assessment models for periodontal disease provide dentists with a precise and consolidated evaluation of the prognosis of periodontitis, enabling the formulation of personalized treatment plans. Periodontal risk assessment systems have been widely applied in clinical practice and research. The application fields of periodontal risk assessment systems vary based on the distinctions between clinical periodontal parameters and risk factors. The assessment models listed below are commonly used in clinical practice, including the periodontal risk calculator (PRC), which is an individual-based periodontal risk assessment tool that collects both periodontal and systemic information for prediction; the periodontal assessment tool (PAT), which allows for quantitative differentiation of stages of periodontal disease; the periodontal risk assessment (PRA) and modified periodontal risk assessment (mPRA), which are easy to use; and the classification and regression trees (CART), which assess the periodontal prognosis based on a single affected tooth. Additionally, there are orthodontic-periodontal combined risk assessment systems and implant periapical risk assessment systems tailored for patients needing multidisciplinary treatment. This review focuses on the current application status of periodontal risk assessment systems.

Classification of bladder cancer based on immune cell infiltration and construction of a risk prediction model for prognosis / 浙江大学学报·医学版

OBJECTIVES@#To classify bladder cancer based on immune cell infiltration score and to construct a risk assessment model for prognosis of patients.@*METHODS@#The transcriptome data and data of breast cancer patients were obtained from the TCGA database. The single sample gene set enrichment analysis was used to calculate the infiltration scores of 16 immune cells. The classification of breast cancer patients was realized by unsupervised clustering, and the sensitivity of patients with different types to immunotherapy and chemotherapy was analyzed. The key modules significantly related to the infiltration of key immune cells were identified by weighted correlation network analysis (WGCNA), and the key genes in the modules were extracted. A risk scoring model and a nomogram for risk assessment of prognosis for bladder cancer patients were constructed and verified.@*RESULTS@#The immune cell infiltration scores of normal tissues and tumor tissues were calculated, and B cells, mast cells, neutrophils, T helper cells and tumor infiltrating lymphocytes were determined to be the key immune cells of bladder cancer. Breast cancer patients were clustered into two groups (Cluster 1 and Custer 2) based on immune cell infiltration scores. Compared with patients with Cluster 1, patients with Cluster 2 were more likely to benefit from immunotherapy (P<0.05), and patients with Cluster 2 were more sensitive to Enbeaten, Docetaxel, Cyclopamine, and Akadixin (P<0.05). WGCNA screened out 35 genes related to key immune cells, and 4 genes (GPR171, HOXB3, HOXB5 and HOXB6) related to the prognosis of bladder cancer were further screened by LASSO Cox regression. The areas under the ROC curve (AUC) of the bladder cancer prognosis risk scoring model based on these 4 genes to predict the 1-, 3- and 5-year survival of patients were 0.735, 0.765 and 0.799, respectively. The nomogram constructed by combining risk score and clinical parameters has high accuracy in predicting the 1-, 3-, and 5-year overall survival of bladder cancer patients.@*CONCLUSIONS@#According to the immune cell infiltration score, bladder cancer patients can be classified. And the bladder cancer prognosis risk scoring model and nomogram based on key immune cell-related genes have high accuracy in predicting the prognosis of bladder cancer patients.

Up-regulation of GINS1 highlighted a good diagnostic and prognostic potential of survival in three different subtypes of human cancer

Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.

Resumo O câncer é uma doença maligna fatal e sua crescente prevalência mundial exige a descoberta de biomarcadores moleculares mais sensíveis e confiáveis. Investigar o nível de expressão de GINS1 e seu valor prognóstico em cânceres humanos distintos, usando uma série de abordagens in silico em várias camadas, pode ajudar a estabelecê-lo como um potencial biomarcador de diagnóstico e prognóstico compartilhado de diferentes subtipos de câncer. O mRNA de GINS1, a expressão da proteína e a metilação do promotor foram analisados usando UALCAN e Human Protein Atlas (HPA), enquanto a expressão de mRNA foi posteriormente validada via GENT2. Os valores prognósticos potenciais de GINS1 foram avaliados por meio do plotter KM. Em seguida, o cBioPortal foi utilizado para examinar as mutações genéticas relacionadas ao GINS1 e as variações do número de cópias (CNVs), enquanto a análise de enriquecimento da via foi realizada usando DAVID. Além disso, uma análise correlacional entre a expressão de GINS1 e células imunes T CD8 + e a construção de uma rede de interação gene-droga foi realizada usando TIMER, CDT e Cytoscape. O GINS1 foi encontrado regulado negativamente em um único subtipo de câncer humano, enquanto comumente regulado positivamente em 23 outros subtipos diferentes. A regulação positiva de GINS1 foi significativamente correlacionada com a sobrevida global pobre (OS) de Carcinoma Hepatocelular de Fígado (LIHC), Adenocarcinoma de Pulmão (LUAD) e Carcinoma de Células Claras Renais de Rim (KIRC). O GINS1 também foi encontrado regulado positivamente em pacientes LIHC, LUAD e KIRC de diferentes características clínico-patológicas. A análise de enriquecimento de vias revelou o envolvimento de GINS1 em duas vias diversas, enquanto poucas correlações interessantes também foram documentadas entre a expressão de GINS1 e seu nível de metilação do promotor, nível de células imunes T CD8 + e CNVs. Além disso, também previmos poucos medicamentos que poderiam ser usados no tratamento de LIHC, LUAD e KIRC, regulando a expressão de GINS1. O perfil de expressão de GINS1 no estudo atual sugeriu que é um novo biomarcador de diagnóstico e prognóstico compartilhado de LIHC, LUAD e KIRC.

Prognostic factors for visual outcome after surgical repair of limbal corneal laceration at a tertiary eye care center in South India

Purpose: To determine the factors affecting the visual outcome after surgical repair of limbal corneal lacerations at a tertiary eye care center in South India. Methods: A retrospective analysis of patients diagnosed with limbal tears between 2011 and 2021 was conducted. Demographic information such as age, gender, cause of injury, and size of the laceration was recorded. Comprehensive ocular examination was performed, including gentle B scan evaluation whenever not contraindicated for detailed posterior segment evaluation. Only those cases with a minimum follow?up of one year were included. Postoperative best?corrected visual acuity, intraocular pressure (IOP), cornea clarity, and integrity of the wound at last follow?up were noted. Results: Out of the 20 patients, 15 (75%) were males and 5 (25%) were females. The mean age was 42.6 � 22.4 years. All 20 patients had a penetrating injury, with four (20%) injured by a stick, two (10%) by an iron rod, three (15%) due to road traffic accident (RTA), three (15%) by glass, and eight (40%) with other nonspecific objects [two (10%) with needle, two (10%) with elastic rope, two (10%) with bangle, and two (10%) with metal]. The average time between the injury and the surgery was 48 hours (2 days). Four (20%) patients underwent a second surgery within a week of repair. After limbal tear repair, at final follow?up at 3 years, 7 (35%) had VA worse than 20/800, 3 (15%) had VA between 20/100 and 20/800, and 10 (50%) achieved VA better than 20/80. Conclusion: Preoperative visual acuity (VA), mode of injury, and size of wound affect the final visual outcome after surgical repair of limbal corneal laceration. Preoperative VA and mode of injury were statistically significant even in the multivariate analysis.

Differential expression of “A Disintegrin and Metalloproteinase 10” in hepatocellular carcinoma and the noncancerous hepatic tissues: Contribution to HCV-promoted hepatocarcinogenesis

Background: A disintegrin and metalloproteinases (ADAMs) have emerged as therapeutic targets in many cancers. ADAM10 was particularly studied in hepatocellular carcinoma (HCC) for its potential role in hepatocarcinogenesis and HCC progression. Objective: To investigate the immunohistochemical (IHC) expression of ADAM10 in HCCs and the adjacent noncancerous tissues from 70 HCC patients, attempting to elucidate any association between ADAM10 and HCC development and/or progression. Materials and Methods: IHC staining for anti-ADAM10 was performed using horseradish peroxidase technique. An extent and intensity-dependent scoring was applied dividing samples into high- and low-expression groups. HCCs were statistically compared in relation with gender, age, cirrhosis, hepatitis C virus (HCV) status, alpha-fetoprotein (AFP) serum level, tumor size, multiplicity, encapsulation/invasion, grade, histological pattern and variant, mitosis, necrosis, vascular emboli, portal thrombosis, stage, recurrence, and mortality. Kaplan–Meier's method was used to analyze disease-free and overall survival (DFS and OS). Results: ADAM10 was expressed in 77.1% of HCCs compared with 42.9% of noncancerous tissues. Differential expression showed significant statistical difference (P = 0.02), as 38.6% of HCCs showed high expression, whereas 92.8% of noncancerous samples showed low expression. No significant differences were observed when high- and low-ADAM10 expression HCCs were compared with respect to all tested prognostic parameters except the HCV status. Patients whose tumors showed high-ADAM10 expression had relatively longer DFS and OS times, but with insignificant log-rank differences. Conclusions: ADAM10 is frequently expressed in HCCs compared with noncancerous hepatic tissues suggesting its role in hepatocarcinogenesis, especially in association with HCV. It has no association with HCC progression or survival. Further studies should be sought to investigate its validity as a therapeutic target.

Comparison of characteristics and laboratory tests of COVID-19 hematological patients from France and Brazil during the pre-vaccination period: identification of prognostic profiles for survival

ABSTRACT Introduction: COVID-19 disease presentation is heterogeneous, from asymptomatic up to severe life-threatening forms. Getting further insights into patients with specific diseases is of particular interest. We aimed to identify profiles of hematology patients hospitalized with COVID-19 that would be associated with survival and to assess the differences between cohorts Methods: A binational cohort of 263 patients with COVID-19 and hematological disease was studied in Paris, France and São Paulo, Brazil. Patient profiles were based on age, comorbidities, biological measurements, COVID-19 symptoms and hematological disease characteristics. A semi-supervised learning method with a survival endpoint was first used, following which, a classifier was identified to allow the classification of patients using only baseline information Main results: Two profiles of patients were identified, one being young patients with few comorbidities and low C-reactive protein (CRP), D-dimers, lactate dehydrogenase (LDH) and creatinine levels, and the other, older patients, with several comorbidities and high levels of the 4 biology markers. The profiles were strongly associated with survival (p < 0.0001), even after adjusting for age (p = 0.0002). The 30-day survival rate was 77.1% in the first profiles, versus 46.7% in the second. The Brazilian analysis emphasized the importance of age, while the French focused on the comorbidities Conclusion: This analysis showed the importance of CRP, LHD and creatinine in the COVID-19 presentation and prognosis, whatever the geographic origin of the patients.

The maximum total point motion (MTPM) in cemented TKAs was higher in 5 years, with a mean value of 0.67 mm (95% confidence interval [CI], 0.52 to 0.87). Uncemented TKAs also presented higher mean MTPM in 5 years (1 mm; 95% CI, 0.82 to 1.22). Uncemented coated ATKs had a higher mean MTPM in 10 years (1.30 mm; 95% CI, 0.70 to 2.39). MTPM was statistically similar in the short- and long-term for cemented and uncemented techniques, with a standardized mean difference of -0.65 (95% CI, -1.65 to 0.35). Conclusion Tibial component migration in TKA was statistically similar at 2, 5, and 10 years in cemented and uncemented techniques, either with or without coating. However, due to the scarce literature, further studies are required with a longer follow-up time.

Conclusão A migração obtida pelo componente tibial na artroplastia total de joelho (ATJ) foi estatisticamente semelhante em 2, 5 e 10 anos ao comparar as técnicas cimentada e não cimentada (com e sem revestimento). Entretanto, devido ao pequeno número de artigos existentes, são necessários mais estudos clínicos sobre tais técnicas e com maior tempo de acompanhamento.

Role of Glut-1 in Tumor Progression and Prognosis in Oral Squamous Cell Carcinoma: A Systematic Review

Introduction: Oral cancer, one of the most common cancers worldwide constitutes a major public health problem and is one of the leading cancer sites among men and women in India. Increased uptake of glucose in cancer cells are mediated by glucose transporters. Among 14 isoforms of glucose transporters, Glucose transporter 1 (GLUT-1) isoform expression predominate Oral squamous cell carcinoma (OSCC). Aim: To emphasize the expression of GLUT-1 in OSCC and to assess its role in tumor progression and prognosis. Materials and Methods: Hand searching and electronic databases such as PubMed/Medline, Google scholar and Science- Direct were done for mesh terms such as OSCC, GLUT-1, prognosis, tumor markers, prognostic marker and risk predictor. Studies were pooled and relevant articles were evaluated. Results: Final analysis identified thirteen articles after considering the inclusion and exclusion criteria. These studies evalu- ated 926 OSCC cases and 70 healthy controls for GLUT-1 immunoexpression. The data was extracted and evaluated manu- ally. GLUT-1 expression was found to be elevated in OPMDs and OSCC than in healthy controls. The pattern of expression of GLUT-1, its correlation with clinico-pathological features, role in tumour progression and prognosis, expression in tumor invasive front, correlation with other markers and role in therapeutics are also discussed in detail

Survival and prognostic factors in bullous pemphigoid: A retrospective cohort study

Background: Bullous pemphigoid is the most common subepidermal autoimmune blistering disease. Till now, the reported prognostic factors in bullous pemphigoid vary considerably. Aims: The purpose of this study was to determine the overall survival rate and prognostic factors in bullous pemphigoid. Methods: We conducted a retrospective cohort study on newly diagnosed bullous pemphigoid patients between July 2001 and November 2019 in a referral unit for autoimmune blistering skin diseases in Romania. Results: One hundred forty-eight patients were included in the study. The Kaplan–Meier overall survival rates at 1, 3, 5 and 10 years were respectively 74.2% (95% confidence interval, 67.5–81.6%), 53.4% (45.7–62.2%), 43.6% (35.9–53%) and 31.3% (23.5–41.7%). The median follow-up among survivors was 48 months (interquartile range: 11–150). Ninety (60.8%) patients died during the follow-up period; of them, 38 (42.2%) had active disease at the time of death. Advanced age, neurological diseases, valvular heart disease, malignancies, use of statins, skin infections and extensive cutaneous involvement were linked to poorer outcomes, while the use of topical corticosteroids was associated with increased overall survival. Limitations: This study lacks a control cohort to validate the obtained results. It was conducted in a retrospective manner in a single centre. In addition, indirect immunofluorescence microscopy was not performed in all patients. Conclusion: Beyond ageing and neurological comorbidities, the prognosis of bullous pemphigoid patients was significantly influenced by the presence of skin infections, valvular heart disease, use of statins and extensive cutaneous involvement. Topical corticosteroid treatment was associated with increased survival in these patients

Influence of Congenital Heart Defect Types over Cardiopulmonary Bypass, Aortic Cross-Clamping, and Intensive Care Unit Length of Stay and Their Association with Genetic Factors

Aim: Surgical correction of congenital heart defects (CHD) often requires interruption of blood flow through cardiopulmonary bypass (CPB) and aortic cross-clamping (ACC), for which duration(s) are considered to be prognostic factors, along with intensive care unit (ICU) length of stay (ICULOS). The aim of this study was to evaluate these surgical prognostic factors in pediatric patients with different types of CHD regarding their type of lesion and associated genetic factors. Study Design: Cross-sectional cohort study with 307 pediatric patients. Place and Duration of Study: Pediatric Intensive Care Unit (ICU) of Hospital da Criança Santo Antônio, in Porto Alegre/RS, Brazil, from 2006-2009 (3 years) Methodology: After inclusion criteria, we studied 266 pediatric patients admitted for the first time in a reference cardiac pediatric ICU from Southern Brazil following cardiac surgery. Intraoperative prognostic factors such as duration of CPB, ACC and ICULOS, in addition to dysmorphological and cytogenetic examinations were compiled and analyzed. P-values of <0.05 were considered significant. Results: CPB time was associated to four outflow tract defects (Tetralogy of Fallot [ToF], transposition of the great arteries [TGA], double outlet right ventricle, and truncus arteriosus [TA]), atrioventricular septal defect, and hypoplastic left heart syndrome (HLHS) (P < 0.001). ACC duration was associated with three outflow tract defects (ToF, TGA, and TA) and HLHS (P < 0.001). Moreover, CPB and ACC times showed an association with cyanotic and complex heart defects, as well as prolonged ICULOS (P < 0.001). There was no relationship between these prognostic factors and syndromic aspects or cytogenetic findings. Conclusions: CHD type has an impact over CPB and ACC duration and ICULOS, whereas genetic factors are not associated with those prognostic factors.

Factores de riesgo relacionados con la evolución intrahospitalaria de pacientes con síndrome coronario agudo con elevación del segmento ST

Fundamento: el síndrome coronario agudo con elevación del segmento ST es uno de los principales motivos de consulta e ingresos en servicios de urgencia. Su curso clínico y pronóstico pueden modificarse por diversos factores. Objetivo: analizar los factores de riesgo relacionados con la evolución intrahospitalaria de los pacientes con síndrome coronario agudo con elevación del segmento ST ingresados en la sala de cuidados intensivos coronarios del Instituto de Cardiología y Cirugía Cardiovascular. Métodos: se realizó un estudio analítico de tipo transversal que incluyó 99 pacientes que con diagnóstico de SCACEST ingresaron en la unidad de cuidados coronarios del Instituto de Cardiología y Cirugía cardiovascular, desde junio del 2018 a junio del 2019. Se recogieron las variables sociodemográficas, clínicas y angiográficas Las variables de respuesta fueron las complicaciones y la muerte de causa cardiovascular ocurrida durante el ingreso hospitalario. Se analizó la distribución de frecuencias, se realizó la prueba de Chi Cuadrado y se emplearon las diferencias de medias para muestras independientes. Resultados: predominaron los pacientes mayores de 60 años, con una edad media de 63 años y el sexo masculino. La hipertensión arterial fue el factor de riesgo más frecuente, seguido del tabaquismo. Se constató que la clasificación de Killip Kimball III-IV tuvo una fuerte asociación con una evolución desfavorable con un OR de 41,50 (p=0,000), seguido del infarto agudo de miocardio previo OR de 3,25 (p=0,03). Conclusiones: la clasificación de Killip Kimball II-IV, la escala Grace de riesgo moderado a alto, y los valores de creatinina tuvieron una mayor asociación con la evolución intrahospitalaria desfavorable.

Background: acute coronary syndrome with ST segment elevation is one of the main reasons for consultation and admissions to emergency services. Its clinical course and prognosis can be modified by various factors. Objective: to analyze the risk factors related to the in-hospital evolution of patients with ST-segment elevation acute coronary syndrome admitted to the coronary intensive care unit of the Institute of Cardiology and Cardiovascular Surgery. Methods: a cross-sectional analytical study was carried out that included 99 patients with a diagnosis of STEACS admitted to the coronary care unit of the Institute of Cardiology and Cardiovascular Surgery, from June 2018 to June 2019. Sociodemographic variables were collected, clinical and angiographic. The response variables were complications and death from cardiovascular causes that occurred during hospital admission. The frequency distribution was analyzed, the Chi Square test was performed and the mean differences for independent samples were used. Results: patients older than 60 years predominated, with a mean age of 63 years and the male sex. Arterial hypertension was the most frequent risk factor, followed by smoking. It was found that the Killip Kimball III-IV classification had a strong association with an unfavorable evolution with an OR of 41.50 (p=0.000), followed by previous acute myocardial infarction OR of 3.25 (p=0.03). Conclusions: the Killip Kimball II-IV classification, the Grace scale of moderate to high risk, and creatinine values ​​had a greater association with unfavorable in-hospital evolution.

Inverse correlation of CD3 & vascular endothelial growth factor in incisional oral squamous cell carcinoma biopsies predicts nodal metastasis & poor survival of patients

Background & objectives: Oral squamous cell carcinoma (OSCC) is widely prevalent in the Indian subcontinent mainly due to habit-associated aetiologies. Immune regulation and angiogenesis are the part of tumourigenesis that play a crucial role in metastasis and survival. However, the concurrent expression of vascular endothelial growth factor (VEGF) and CD3 (immune regulator receptor on T-lymphocyte) in the same OSCC tissue samples has not been reported in the Indian population. The present study evaluated the expression of CD3+ T-cells and VEGF in OSCC tissue samples and studied the clinicopathological correlation and survival analysis in an Indian population. Methods: This was a retrospective study conducted on 30 formalin-fixed and paraffin embedded sections which were histologically diagnosed as OSCC cases comprising of 15 metastatic OSCC and 15 non- metastatic OSCC with available clinical data and survival status. Results: Reduced expression of CD3+ T-cells and increased VEGF expression were observed in metastatic OSCC samples. The correlation of expression of CD3+ T-cells and VEGF with clinicopathological parameters showed a significant association between these markers with age, nodal status, site of the lesion and survival. Interpretation & conclusions: Reduced expression of CD3+ T-cells in OSCC was found to be associated with a significantly poor survival. VEGF was found to be over expressed in metastatic OSCC as compared to that in non-metastatic OSCC. The study findings suggest that the evaluation of CD3 and VEGF in incisional OSCC biopsies can be considered for predicting the survival outcome and metastasis

The Correlation between QRS Dispersion and Coronary Artery Disease Severity in Patients with Non ST Elevation Myocardial Infraction

Non ST elevation myocardial infarction (NSTEMI) has been the subject of numerous studies. Risk stratification is a fundamental element for the management of NSTEMI; therefore, several scores have been established in this direction, particularly prognostic markers derived from the ECG. Aims: The aim of our study is to correlate the dispersion of the QRS with the severity of coronary lesions assessed by the GENSINI score in patients admitted for NSTEMI at the University Hospital of Marrakech. Methods: A retrospective study was conducted in the cardiology department of Mohammed VI university hospital of Marrakech from January 01, 2022 to March 31, 2022. Data was derived from the hospitalization register, including 30 patients (16 women and 14 men). Age ranged from 56 to 74 years with an average of 64.6 ± 9.3. Data was analyzed by SPSS, the level of significance set at p <0.05. Results: We found, in our study, a highly significant positive correlation between QRS dispersion (considered important if >20 ms) and admission heart rate (p=0.003) as well as the level of ultrasensitive troponins (p=0.003). There is also a very significant correlation between QRS dispersion and corrected QT interval (p=0.005), Moreover, we concluded that in patients admitted for NSTEMI, the greater the dispersion of the QRS, the higher the score of GENSINI (p<0.0001). Conclusion: The dispersion of the QRS is a simple marker on the ECG that can have a predictive value in different clinical contexts, particularly in acute ischemic heart disease. Further studies are needed, however, to validate its usefulness in routine practice.
