A positive correlation between serum lactate dehydrogenase level and in-hospital mortality in ICU sepsis patients: evidence from two large databases

BackgroundSepsis presents a significant healthcare challenge, characterized by high morbidity and mortality rates. There is a scarcity of relevant studies investigating the association between serum lactate dehydrogenase level and the prognosis of sepsis in patients from intensive care unit, with smaller sample sizes compared to other studies.MethodsA retrospective analysis was conducted utilizing data from the Second Affiliated Hospital of Guangzhou Medical University and the Medical Information Mart for Intensive Care IV (MIMIC-IV). The primary outcome was the in-hospital mortality. Multivariate Cox proportional hazards regression was adopted to assess the independent association. Receiver operator characteristic (ROC) curve was used to evaluate the predictive value.ResultsWe included a total of 2148 patients in the Guangzhou Sepsis Cohort (GZSC) database and 5830 patients in the MIMIC-IV database. In multivariate Cox proportional hazards regression, high levels of LDH are significantly associated with higher mortality (HR = 1.21, 95% CI 1.13–1.30, p < 0.001 in the GZSC database and HR = 1.19, 95% CI 1.13–1.25, p < 0.001 in the MIMIC-IV database). The ROC curves showed that the AUC of LDH was 0.663 in the GZSC database and 0.660 in the MIMIC-IV database.ConclusionsA lower lactate dehydrogenase level is associated with reduced in-hospital mortality among patients with sepsis, suggesting its potential as a valuable marker for predicting prognosis in this patient population.

Evaluation of Ki-67 expression and large cell content as prognostic markers in MZL: a multicenter cohort study

Marginal zone lymphoma (MZL) can have varied presentations and pathologic features, including high Ki-67 expression ( > 20%) as well as increased numbers of large B cells (LC). However, there are limited data available demonstrating the prognostic significance of these variables in patients with MZL. In this multi-institutional retrospective cohort study of patients with MZL treated at 10 centers, we evaluated the association between the presence of Ki-67 expression and increased LCs on survival and risk of histologic transformation (HT). A total of 785 patients were included (60% with extranodal MZL, 20% with nodal MZL, and 20% with splenic MZL). Among the 440 patients with Ki-67 staining, 22% had high Ki-67 (Ki-67 >20%). The median progression-free survival (PFS) for patients with high Ki-67 was 5.4 years compared to 7.0 years for patients with low Ki-67 (HR = 1.45, 95%CI = 1.03–2.05). Ki-67 > 20% strongly correlated with high LDH level. The risk of HT was higher in patients with increased Ki-67 than those without (5-year risk, 9.8% vs 3.87%, p = 0.01). Twelve percent of patients had LC reported on biopsy with 6% having >10% LC. The presence of LC was associated with high Ki-67 (p < 0.001), but not associated with shorter PFS or overall survival (OS). The cumulative risk for HT was higher in patients with LC compared to those without LC (5-year risk, 9.4% vs 2.9%, p = 0.04). Receipt of anthracycline-based therapy did not impact PFS or OS in either group. Ki-67 staining >20% was a prognostic factor for worse survival and strongly correlated with elevated LDH. Novel therapies should be investigated for their potential ability to overcome the high-risk features in MZL. Our data reinforce the importance of obtaining biopsies at relapse or progression, particularly in patients with baseline high Ki-67 and increased LCs, given their increased risk for HT.

Outcomes and predictors of progression in progressive pulmonary fibrosis

Background Progressive pulmonary fibrosis (PPF) is a general term for a class of interstitial lung diseases (ILDs) characterized by a progressive fibrosing (PF) phenotype. Patients with PPF have decreased lung function, exercise ability, and quality of life. The purpose of this study was to investigate the clinical characteristics, potential associated factors for disease progression, and survival outcomes of patients in the PPF population. Methods This study retrospectively reviewed the data of patients diagnosed with ILD between January 2011 and December 2022 at The First Affiliated Hospital of Ningbo University. A PF phenotype was defined based on the criteria that were used in the PPF clinical practice guidelines, which led to the identification of 92 patients with a PF phenotype among the 177 patients with fibrotic ILD. Baseline clinical information and laboratory parameters were collected and analysed in our cohort. Results Patients in the PPF group had higher tumour marker levels and lower pulmonary function test results at baseline than did those in the non-PPF group. According to the multivariate logistic regression analysis, age >65 years (OR 2.71, 95% CI 1.26-5.89; p = 0.011), LDH >245 U/L (OR 3.07, 95% CI 1.39-6.78; p = 0.006), CA-153 > 35 U/mL (OR 3.16, 95% CI 1.25-7.97; p = 0.015), FVC <60% predicted (OR 4.82, 95% CI 1.60-14.51; p = 0.005), DLCO <50% predicted (OR 3.21, 95% CI 1.43-7.21; p = 0.005), and the UIP-like pattern on chest HRCT (OR 3.65, 95% CI 1.33-10.07; p = 0.012) were potentially associated with the progression of fibrotic interstitial lung diseases (f-ILDs) to PPF. Furthermore, the PPF group had a poorer survival rate than the non-PPF group (p = 0.0045). According to the multivariate Cox regression analysis, an SPAP ≥ 37 mmHg (HR 2.33, 95% CI 1.09-5.00; p = 0.030) and acute exacerbation (HR 2.88, 95% CI 1.26-6.59; p = 0.012) were identified as significant prognostic factors for mortality in patients with PPFs. Conclusions Patients who were older, had high CA-153 and LDH levels, had poor pulmonary function test results, or had a UIP-like pattern on chest HRCT were more likely to have indications for the progression of f-ILD to PPF. Increased SPAP and AE are independent risk factors for the prognosis of PPF patients, so additional attention should be given to such patients.

Neuropsychiatric manifestations of hospitalized patients with coronavirus disease 2019 during the second wave in Egypt

BackgroundStudies suggested that COVID-19 virus causes neurological and psychiatric manifestations with different mechanisms. However, prevalence of neurological and psychiatric manifestations among COVID-19 patients varies across studies from 18.1%: 82.3%. The objective of this study was to determine neuropsychiatric manifestations in a sample of Egyptian COVID-19 hospitalized patients during the second wave of the pandemic and to detect factors affecting neurological and psychiatric prevalence. This cross-sectional study was conducted at Ain Shams university isolation hospitals and included 110 hospitalized COVID-19 patients, over a 2-month period from June 2021 to August 2021. Patients underwent a careful history taking, full neurological examination including Mini-Mental State Examination, the Structured Clinical Interview for DSM-IV (SCID I), COVID-19 severity criteria. Any available imaging and laboratory tests were recorded.Results83 (75.5%) patients had neurological manifestations. The most common neurological manifestations were headache (50.9%), hypogeusia (24.5%), hyposmia, paresthesia (23.6% each) and coma (15.5%). After exclusion of 17 patients who could not be examined by Mini-Mental State Examination, psychiatric manifestations were seen in 56 patients (61.5%) out of the remaining 91 patients. The most prevalent psychiatric disorders were delirium (30.8%), depression (19%), and adjustment disorder (17.5%). Moreover, hypertension, COVID-19 severity, place of admission, and high levels of LDH and ALT affected neurological manifestations prevalence.ConclusionsCOVID-19 infection and its immune reaction along with its social and psychological effects have a great impact on mental and physical health. Hence, neuropsychiatric evaluation cannot be ignored in any case with COVID-19 infection.

Hyperprogressive disease in patients with advanced cancer treated with immune checkpoint inhibitors.

Hyperprogressive disease (HPD) is a new phenomenon developing in the era of immune checkpoint inhibitor (ICI) therapy. HPD is characterized by an unexpected and fast progression in tumor volume and poor survival. There is no standardized definition for HPD and clinicopathological variables associated with HPD are unclear. Herein, we assessed incidence, treatment outcomes and factors predictive of HPD in patients treated with ICIs. We retrospectively analyzed patients with advanced cancer treated with ICI at one academic center between 2014 and 2021. We used the Lo Russo's adopted criteria combined with clinical and radiologic parameters for the definition of HPD. All patients who underwent their first tumor evaluation according to RECIST1.1 were included. Of 155 patients, 147 were eligible for analysis. The median age was 61 and 83% were male. The cancer types were; lung 67.3%, bladder 12.9%, gastric 9.5%, 5, colon 5.4% and renal cell carcinoma 4.8%. 59.9% of patients were treatment-naive and others had one or more lines of chemotherapy. 19 (12.9%) patients had HPD. In patients who had HPD, progression-free survival (PFS) was significantly shorter (1.5 vs 9.8months, (HR 9.56; 95% CI (5.51-16.57), p < 0.001). The median overall survival (OS) was also shorter for HPD patients than non-HPD (3.0 vs 23.1months, respectively, HR 12.03, 95% CI (6.64-21.81), p < 0.001). Gastric cancer, larger sum of target lesion diameters at baseline, liver metastases, higher LDH level and higher neutrophil-lymphocyte ratio (NLR) were significantly associated with HPD. Our findings demonstrated that HPD was a rapid phenomenon with significantly poor survival rates. Several clinicopathological factors and tumor characteristics might indicate HPD.

Clinicopathological characteristics, prognostic factors, and outcomes of elderly patients with lymphoma-associated hemophagocytic lymphohistiocytosis: A multicenter analysis.

Lymphoma is the most common secondary cause of hemophagocytic lymphohistiocytosis (HLH) in adults. Lymphoma-associated HLH (LA-HLH) in the elderly population is not rare, however, little has been reported regarding clinicopathological characteristics, prognostic factors, and outcomes of LA-HLH in the elderly population. We retrospectively analyzed a multicenter cohort of elderly patients with LA-HLH. Clinicopathological features and treatment information were collected. The impacts of baseline characteristics and treatments on survival outcomes were analyzed. A total of 173 elderly patients with LA-HLH were included. Compared with young patients, elderly patients showed different clinical and laboratory features. Regarding lymphoma subtypes, B-cell lymphoma was more common in elderly patients (elderly 61.3% vs. young 32.3%, p < 0.001) while T/NK-cell lymphoma was more common in young patients (65.3% vs. 35.3%, p < 0.001). The median survival of elderly patients with LA-HLH was only 92 days. The prior use of HLH therapy or etoposide-containing HLH therapy was not associated with improved overall survival. T/NK-cell subtype, a lower platelet count (≤53 × 109/L), a lower albumin level (≤32.1 g/L), a higher LDH level (>1407 U/L), and a higher creatinine level (>96.8 μmol/L) were independent predictors of decreased overall survival and 60-day survival. A prognostic index was established and demonstrated to be robust in predicting the overall survival and 60-day survival of elderly patients with LA-HLH. LA-HLH in elderly patients displayed heterogeneous clinicopathological features and survival outcomes. Treatments need to be optimized to improve the outcomes of elderly patients with LA-HLH.

A comparison of clinical profile and treatment outcome of Hodgkin’s Lymphoma in Tanzania according to HIV status during the HAART era

BackgroundThe incidence of Hodgkin's lymphoma (HL) in people living with HIV (PLWHA) and on HAART is approximately 20–30 times higher than in HIV-negative individuals. Most patients with HIV-HL present at an advanced stage (III-IV) have 'B' symptoms and extranodal involvement. The natural history and risk stratification of HIV-HL has undergone a significant change as a result of HAART's rollout. This study investigated the differences in clinicopathological and survival patterns of HL among individuals with and without HIV disease in Tanzania during the HAART era.MethodologyThis hospital-based retrospective cohort study was conducted at the ORCI, Dar-Es-Salaam, Tanzania. Chi-square and Fisher’s exact tests were used to compare proportions. The student t-test was used to compare means. To determine factors that predict survival, we used the log-rank test to analyze the variables in univariate analysis. A Cox regression model was used to analyze the significant factors from univariate analysis in multivariate analysis.ResultsEighty-three patients with HL were recruited, and the prevalence of HIV-positive status was 27.7%. Most of the patients with HIV-HL had an age of > 30 years (73.9%), while most of the non-HIV-HL patients had an age of ≤ 30 years (63.3%) (P = 0.02). The 2-year OS rate for HIV-HL was 34%, while that for non-HIV-HL was 67%. Among the HIV-HL patients, predictors of a poorer outcome were a CD4 count ≤ 200 cells/mm3 (P = 0.05), lack of HAART use (P = 0.00), and the use of HAART for ≤ 10 months (P = 0.00).ConclusionThe prevalence of HIV-HL was 27.7% among HL patients. HIV positivity is still a poor prognostic factor in our setting, especially for patients not on HAART, on HAART for ≤ 10 months, or with a low CD4 count below 200 cells/mm3. Patients with HIV-HL were older and had higher LDH levels, whereas patients with non-HIV-HL were younger and had low LDH levels.

Investigating the Hepcidin Gene Polymorphisms in COVID-19-Associated Mucormycosis Susceptibility: A Clinical-Laboratory Study.

Following the coronavirus disease 2019 outbreak (COVID-19), it became a worrisome health burden worldwide. COVID-19-associated mucormycosis emergence, characterized by dysregulated inflammation and iron metabolism, exacerbated the prognosis of affected patients. Given the significance of hepcidin in regulating inflammation and iron metabolism, this study investigated the significance of hepcidin single nucleotide polymorphisms (SNP) in COVID-19-associated mucormycosis development, along with the association between the clinical and laboratory factors and COVID-19-associated mucormycosis. From September 2021 to November 2021, COVID-19 patients with and without mucormycosis were enrolled in this cross-sectional study. Their medical records and laboratory results were investigated. SNP genotyping was performed using Sanger sequencing. Hardy-Weinberg Equilibrium, Pearson's Chi square, and student t test were used for analyzing the data using SPSS software version 25. P<0.05 was regarded as statistically significant. Here, 110 COVID-19 patients with and without mucormycosis were investigated. Elevated levels of urea, aspartate aminotransferase, lactate dehydrogenase, and increased ratio of polymorphonuclear neutrophil to lymphocytes were associated with decreased risk of COVID-19-associated mucormycosis in patients (all P<0.05). Moreover, diabetes mellitus increased the risk of mucormycosis (P=0.028). In contrast to patients without mucormycosis, patients with mucormycosis did not display 442 GA and SNP335 GT genotypes. Unlike patients without mucormycosis, none of the patients with mucormycosis had SNP442 GA and SNP335 GT genotypes. Regarding SNP 443 C>T, and the combination of SNPs 582 A>G and 443 C>T, CC genotype and AA+CC genotypes were associated with increased lactate dehydrogenase levels in COVID-19 patients, respectively. Regarding SNP 443 C>T, the CC genotype was associated with increased lactate dehydrogenase levels in COVID-19 patients. In terms of SNP 582 A>G and SNP 443 C>T, COVID-19 patients with AA+CC genotypes had higher levels of LDH. None of the patients with mucormycosis had SNP442 GA and SNP335 GT genotypes.

The serum LDH level and KELIM scores are potential predictors of a benefit from bevacizumab first-line therapy for patients with advanced ovarian cancer.

The survival benefit of first-line treatment with bevacizumab in advanced ovarian cancer patients are multifaceted. In our study, we aimed to identify potential markers of bevacizumab efficacy to help predict which patients would experience survival benefits. This was a retrospective analysis of 114 patients examined from January 1, 2015, to March 1, 2023, and data on clinical, biological, and imaging variables, such as ascites, serum LDH, and CA125, were extracted from electronic medical records. We performed a correlation analysis and principal component analysis to investigate correlations among variables and reduce their dimensionality. Then, univariate and multivariate Cox proportional hazards regression analyses were used to identify the predictors of progression-free survival. Favorable KELIM score (≥ 1, HR 0.376, 95% CI [0.202-0.700], p = 0.002), which indicated better chemosensitivity, and lower LDH levels (≤ 210 U/L, HR 38.73, 95% CI [6.108-245.6], p < 0.001) were found to be independent predictors of a treatment benefit with bevacizumab in patients with advanced ovarian cancer. Regardless of LDH level, patients with favorable KELIM scores had a higher progression-free survival (PFS) benefit (p = 0.18). Among patients with unfavorable KELIM scores, those with higher LDH levels had the lowest PFS benefit (median: 11.5months, p = 0.0059). Patients with poor chemosensitivity and low LDH levels are more likely to benefit from first-line bevacizumab treatment. The combination of the two markers can be a helpful predictor of patients who are most likely to benefit from treatment and a guide for treatment decisions-making.

Clinical and epidemiological profile of patients with atypical melanomas treated with immunotherapy.

e21532 Background: Atypical melanomas, such as acral lentiginous, uveal, mucosal, spitzoid, desmoplastic, meningeal, and primary occult site, represent less than 5% of melanoma cases. Due to their different biological tumor behavior from cutaneous melanomas, their treatment is still challenging. Currently, checkpoint inhibitors are the main treatment based on extrapolations or data from small surveys. Methods: This study aims to describe the epidemiological profile, clinical and pathological characteristics, and treatment of patients with atypical melanomas treated with immunotherapy. It is an observational, descriptive, retrospective study that analyzed 72 medical records of patients with atypical melanomas, ECOG 0-1, &gt; 18 years old, treated with immunotherapy (neo, adjuvant, and palliative lines), between January 2015 and December 2023 at the A.C. Camargo Cancer Center, São Paulo, Brazil. Results: We gathered 72 patients, 61% male and 39% female, with an average age of 58.89 (±13.63) years; 57% were white, 15% African-descendant (black and brown), 8% Asian, and 20% not specified. Regarding primary site, 26% were acral, 24% mucosal, 24% occult primary site, 15% uveal, 8% desmoplastic, 1% amelanocytic, 1% spitzoid, and 1% cauda equina meningeal. Regarding staging, (3%) were stage I, (15%) stage II, (25%) stage III, (47%) stage IV, and (10%) unknown. LDH: 372.5 (±360) mg/dL. Metastases: lymph node 29%; hepatic 23%; pulmonary 21%; bone 18%; central nervous system 15%; peritoneal carcinomatosis 5%; stomach 3%; cauda equina 3%; adrenal 1%; in transit 1%; intestine 1%; bone marrow 1%; parotid 1%. BRAF mutations were present in 23% of cases (variants V660E, V600K, V660R, and G469R); NRAS 6% (codons 13 and 61); KIT 1% (exon 11) and NTRAK 1% (S701F). In relation to treatment, 5 received neoadjuvant anti-pd1 + anti-ctla4 combination, 13 adjuvant with anti-pd1+/- anti-ctla4. About 50 patients received systemic treatment for metastatic disease anti-pd1+/- anti-ctla4. Overall survival: 26 (±14.8) months. Conclusions: Atypical melanoma primary occult site is the most prevalent, with the majority diagnosed at stage IV, with high LDH levels and lymph nodes as the main sites of metastases. Twenty-three percent had a BRAF gene mutation. The majority were treated palliatively with first-line immunotherapy, with median survivals of 14.8 months.

COMPARISON OF DIFFERENT CLINICAL OUTCOMES AMONG ASTHMATIC AND NON-ASTHMATIC COVID-19 PATIENTS IN AN INTENSIVE CARE UNIT SETTING

Objectives: To compare the different clinical outcomes among asthmatic and non-asthmatic patients having COVID-19 in an ICU setting Materials and Methods: A cross-sectional study was conducted in the Covid ICU of Hayatabad Medical Complex Peshawar from April 2021 to September 2022. WHO validated questionnaire was used among 220 study participants who were selected in this study. A modified questionnaire was tested for validation through a pilot study. A Cronbach alpha of less than 0.80 was considered acceptable. A significant P value was considered as &lt; 0.05. SPSS version 22 was used for data analysis. Results: Out of a total of 220 participants, 10.9% (n= 24) were asthmatic while 89.1% (n= 196) were non-asthmatic. The majority of participants were non-asthmatic male 118 (60.2%, p-value 0.86). Different comorbidities were seen in different patients, most of the non-asthmatic patients, 81 (41.3%, p-value 0.57) had more than one co-morbidity. Most of the non-asthmatic patients, 178 (90.8%, p-value 0.40) had consolidation on their chest X-rays while 23 asthmatics (95.8%, p-value 0.40) had consolidation on their chest X-rays. The majority of the non-asthmatic patients, 161 (82.1%, p-value 0.23) had high D-dimer levels. Ventilator use in the hospital was found in the majority of the non-asthmatic patients (183/93.4%, p-value 0.75) while, 22 asthmatic patients (91.7%, p-value 0.75) were found to be on a ventilator. The majority of non-asthmatic patients had high levels of serum LDH, D-dimer, and Ferritin. Twenty asthmatic patients (83.3%, p-value 0.21) had severe ARDS, and 169 non-asthmatic patients (86.2%, p-value 0.21) had severe ARDS. The number of days of hospitalization was found more among the majority of the asthmatic patients (23/95.8%, p-value 0.61) and in non-asthmatic patients, 176 (89.8, p-value 0.61) were admitted to the hospital for 20 days. Conclusion: COVID-19 disease was found higher among non-asthmatic patients as compared to asthmatic patients. The presence of other significant comorbidities also increases COVID-19 infection severity. Key Words: Asthmatic, Non-Asthmatic, COVID-19, Comorbidities, Ventilator.

Predictors of Survival, Treatment Modalities, and Clinical Outcomes of Diffuse Large B-Cell Lymphoma in Patients Older Than 70 Years Still an Unmet Medical Need in 2024 Based on Real-World Evidence.

Diffuse large B-cell lymphoma (DLBCL) especially affects the older population. Old (≥60 years) and very old age (≥80 years) DLBCL patients often present high-risk molecular alterations, lower tolerability to conventional immunochemotherapy, and poor clinical outcomes. In this scenario, attenuated therapeutic strategies, such as the R-MiniCHOP and R-MiniCHOP of the elderly regimens, have emerged for this particularly fragile population. However, the responses, clinical outcomes, and toxicities of these regimens currently remain poorly understood, mainly because these individuals are not usually included in controlled clinical trials. This retrospective, observational, and single-center real-world study included 185 DLBCL, NOS patients older than 70 years treated at the largest oncology center in Latin America from 2009 to 2020. We aimed to assess the outcomes, determine survival predictors, and compare responses and toxicities between three different primary therapeutic strategies, including the conventional R-CHOP regimen and the attenuated R-MiniCHOP and R-MiniCHOP of the elderly protocols. The median age at diagnosis was 75 years (70-97 years), and 58.9% were female. Comorbidities were prevalent, including 19.5% with immobility, 28.1% with malnutrition, and 24.8% with polypharmacy. Advanced clinical stage was observed in 72.4%, 48.6% had bulky disease ≥7 cm, 63.2% had B-symptoms, and 67.0% presented intermediate-high/high-risk IPI. With a median follow-up of 6.3 years, the estimated 5-year OS and PFS were 50.2% and 44.6%, respectively. The R-MiniCHOP of the elderly regimen had a lower ORR (p = 0.040); however, patients in this group had higher rates of unfavorable clinical and laboratory findings, including hypoalbuminemia (p = 0.001), IPI ≥ 3 (p = 0.013), and NCCN-IPI ≥ 3 (p = 0.002). Although associated with higher rates of severe neutropenia (p = 0.003), the R-CHOP regimen promoted increased OS (p = 0.003) and PFS (p = 0.005) in comparison to the attenuated protocols. Additionally, age ≥ 75 years, high levels of LDH, B-symptoms, advanced clinical stage (III/IV), neutrophilia, and low lymphocyte/monocyte ratio were identified as poor prognostic factors in this cohort. In this large and real-life Latin American cohort, we demonstrated that patients with DLBCL, NOS older than 70 years still do not have satisfactory clinical outcomes in 2024, with half of cases not reaching 5 years of life expectancy after diagnosis. Although the conventional R-CHOP offers response and survival advantages over attenuated regimens, its myelotoxicity is not negligible. Therefore, the outcomes reported and the prognostic factors here identified may assist clinicians in the appropriate selection of therapeutic strategies adapted to the risk for old and very old DLBCL patients.

Peculiarities of pharmacological prevention strategy of pancreatic complications after endoscopic papillosphincterotomy for choledocholithiasis

The most frequent complication of endoscopic papillosphincterotomy (EPST) is acute pancreatitis. This complication is supposed to be based on mechanical, chemical, hydrostatic, enzymatic and thermal impact on pancreatic ducts and parenchyma. According to different literature data, the incidence of post-EPST pancreatitis (PEP) varies from 30 to 40%, and the mortality rate is 2-10%. The aim of the investigation was to expand information about peculiarities of early diagnostics and prevention of post-EST pancreatitis at the present stage. To reach the set goal we analyzed 559 case histories of patients with diagnosed cholelithiasis, 319 of them underwent EPST. During the study it was found out, that elevated neutrophils/lymphocytes ratio over 4,96 (p=0,001), high LDH level over 250 IU/ml (p=0,01), as well as C-reactive to albumin index over 0,180 (p=0,001) are reliable markers of early diagnosis. Also, indirect diagnostic markers of PEEP are biochemical signs of cholestasis and cytolysis of hepatocytes, as well as hyperglycemia combined with glucosuria. We consider the inclusion of intraoperative injections of papillotomy wound margins with Epinephrine in combination with subsequent Somatostatin administration in combination with rectal Diclofenac and intravenous hydration with Reamberin to be the most effective strategy for PEP prevention. Thus, we can conclude that despite the ongoing research and the search for effective algorithms for the prevention and early diagnosis of PEP, their data often contradict each other or simply do not confirm their effectiveness. The problem of prevention and diagnosis of PEP remains complex and requires further study. There are discrepancies, sometimes significant ones, in the current literature, which provides grounds for the development and research of new methods of early diagnosis and prevention.

Pediatric Hodgkin Lymphoma Overview in Albania during the Last Decade

Background: Hodgkin lymphoma (HL) is a rare malignancy characterized by a malignant proliferation of cells in the reticuloendothelial system, mainly lymph node, and the presence of Reed-Sternberg cells with a relatively good prognosis compared to other pediatric malignancies. This study aimed to produce epidemiologic and clinical data on HL for Albania, aiming for a better understanding of the disease presentation to diagnose it at an earlier stage with the result of a better outcome. Methods and Results: This single-center, retrospective study performed in the Mother Theresa University Hospital Center (Tirana, Albania) analyzed epidemiological and clinical data of pediatric patients under 14 years of age diagnosed with HL during a 10-year study period from 2012 to 2022. During the last 10 years, 25 children (ages 0-14) were diagnosed with HL at UHC "Mother Theresa," Tirana. From the demographic data of our study, most patients (68%) were in the age group of 10-14. The male-to-female ratio was 2.12:1. The first clinical presentation was mainly because of lymphadenopathy in 92% of patients, with the presence of B symptoms in 68%.In most cases, the CBC was not affected, yet 24% of patients had high platelets, and 12% had low RBCs, while WBCs increased in 16% of patients and decreased in 12%.Lymphopenia and monocytosis were found in more than half of cases. Around 68% of patients had high levels of LDH and CRP. ESR and ALP were high in 64% of patients, Ferritin was high in 32%, and fibrinogen level was high in 28%.According to the Ann Arbor system, most of our patients were at stage II (32%), followed closely by stage I (28%) and stage III (24%), and only 16% were at stage IV upon presentation.The most common histopathologic type was nodular sclerosis classical HL, presented in 44% of cases. Conclusion: HL is a relatively frequent pediatric malignancy in young adults, affecting mainly males, and is diagnosed at a relatively early stage in our country.

Differentiation of benign and metastatic lymph nodes in soft tissue sarcoma

Lymph node metastasis (LNM) occurs in less than 5% of soft tissue sarcoma (STS) patients and indicates an aggressive course of disease. Suspicious lymph nodes (LN) in staging imaging are a frequent topic of discussion in multidisciplinary tumor boards. Predictive markers are needed to facilitate stratification and improve treatment of STS patients. In this study, 56 STS patients with radiologically suspicious and subsequently histologically examined LN were reviewed. Patients with benign (n = 26) and metastatic (n = 30) LN were analyzed with regard to clinical, laboratory and imaging parameters. Patients with LNM exhibited significantly larger short axis diameter (SAD) and long axis diameter (LAD) vs. patients with benign LN (median 22.5 vs. 14 mm, p < 0.001 and median 29.5 vs. 21 mm, p = 0.003, respectively). Furthermore, the presence of central necrosis and high maximal standardized uptake value (SUVmax) in FDG-PET-CT scans were significantly associated with LNM (60 vs. 11.5% of patients, p < 0.001 and median 8.59 vs. 3.96, p = 0.013, respectively). With systemic therapy, a slight median size regression over time was observed in both metastatic and benign LN. Serum LDH and CRP levels were significantly higher in patients with LNM (median 247 vs. 187.5U/L, p = 0.005 and 1.5 vs. 0.55 mg/dL, p = 0.039, respectively). This study shows significant associations between LNM and imaging features as well as laboratory parameters of STS patients. The largest SAD, SUVmax in FDG-PET-CT scan, the presence of central necrosis, and high serum LDH level are the most important parameters to distinguish benign from metastatic LNs.

Targeted therapy or immunotherapy in BRAF-mutated metastatic melanoma: a Spanish center's decade of experience.

Targeted therapies and immunotherapy are currently considered the mainstay first-line treatment for advanced BRAF-mutated melanoma. However, the impact of treatment (targeted therapy and immunotherapy) and the prognostic factors are still not clear. Medical records of 140 patients diagnosed with advanced melanoma between 2011 and 2021 were retrospectively reviewed to extract demographic, BRAF status, treatment, performance status, and survival data. ORR, PFS, and OS were compared between patients diagnosed with advanced melanoma and treated with first-line IT or BRAF/MEKi. The prognostic factors were assessed using Cox regression models. In all patients and those treated with immunotherapy, we did not find any effect of BRAF status on ORR, PFS, or OS. In patients with BRAF-mutated melanoma, ORR was 43.8% vs. 70% (P=0.04), PFS was 19.2 vs. 11.5 months (p=0.22), and OS was 33.4 vs. 16.4 months for the immunotherapy and targeted therapy groups, respectively (P=0.04). ECOG, presence of brain metastases, and high LDH level from initiation of first-line treatment were all associated with differences in PFS and OS. Patients with advanced BRAF-mutated melanoma treated with first-line immunotherapy had a significantly longer PFS and OS than those treated with first-line BRAF/MEKi; however, first-line BRAF/MEKi treatment had a significantly higher ORR than first-line immunotherapy.

Shorter antitubercular therapy for extrapulmonary tuberculosis - a case report

IntroductionExtrapulmonary tuberculosis (EPTB) adds to India’s significant economic burden, with pericardial effusion being a potentially fatal complication. This case report highlights the need for early diagnosis and the feasibility of shorter-duration treatment for EPTB in developing countries.PresentationThis case report describes a 19-year-old male from Southeast Asia who had a history of bronchiectasis involving the left lower lobe and the right middle lobe, which was cystic in nature, as well as multiple episodes of non-tuberculous pneumonia. Currently, he presented with fever, hypotension, tachycardia, and acute kidney injury. Echocardiogram showed left ventricular dysfunction with a left ventricular ejection fraction (LVEF) of 45% and moderate pericardial effusion. Early signs of cardiac tamponade were noted, specifically the absence of respiratory variation in the right ventricle and left ventricle collapse. Emergent pericardiocentesis was performed, and hemorrhagic pericardial fluid was aspirated. Fluid analysis revealed high levels of LDH (5000 U/L), polymorphonuclear leukocytosis, and acid-fast bacilli that were visualized on microscopy, which led to the diagnosis of pericardial tuberculosis. A CT of the abdomen showed hepatosplenomegaly and polyserositis. Empirically, antitubercular therapy consisting of isoniazid, rifampin, pyrazinamide, and ethambutol was administered for 2 months and isoniazid along with rifampicin was given for the next 4 months. Serial echocardiograms in the following months showed an improvement in LVEF (55%) and decreased effusion. However, during this treatment period, due to frequent episodes of pneumonia, the evaluation of immunodeficiency disorders was performed and revealed low levels of IgG (4.741 g/L), IgA (0.238 g/L), and IgM (0.098 g/L). He was diagnosed with common variable immunodeficiency disease and received intravenous immunoglobulin therapy.ConclusionThis report emphasizes the timely identification of cardiac tamponade and the effective management of EPTB through a shorter-than-recommended course of antitubercular therapy, resulting in the alleviation of symptoms and better overall health outcomes.

Spontaneous pneumomediastinum in anti-MDA5-positive dermatomyositis: Prevalence, risk factors, and prognosis

ObjectiveTo depict the clinical panorama of spontaneous pneumomediastinum (SPM) in anti-MDA5 antibody-positive dermatomyositis (anti-MDA5+ DM). MethodsA total of 1352 patients with idiopathic inflammatory myopathy (IIM), including 384 anti-MDA5+ DM patients were retrospectively enrolled. The clinical profiles of anti-MDA5+ DM-associated SPM were analyzed. ResultsWe identified that 9.4 % (36/384) of anti-MDA5+ DM patients were complicated with SPM, which was significantly higher than that of non-anti-MDA5+ DM and other IIM subtypes (P all <0.001). SPM developed at a median of 5.5 (3.0, 12.0) months after anti-MDA5+ DM onset. Anti-MDA5+ DM patients complicated with SPM showed a significantly higher frequency of fever, dyspnea, and pulmonary infection including viral and fungal infections compared to those without SPM (P all < 0.05). Cytomegalovirus (CMV) and fungal infections were identified to be independent risk factors for SPM development in the anti-MDA5+ DM. SPM and non-SPM patients in our anti-MDA5+ DM cohort showed comparable short-term and long-term survival (P = 0.236). Furthermore, in the SPM group, we found that the non-survivors had a lower peripheral lymphocyte count, higher LDH level, and higher frequency of intensification of immunosuppressive treatment (IST) than survivors. The elevated LDH level and intensification of IST were independent risk factors for increased mortality in anti-MDA5+ DM-associated SPM patients. ConclusionsNearly one-tenth of patients with anti-MDA5+ DM develop SPM. Both CMV and fungal infections are risk factors for SPM occurrence. The development of SPM does not worsen the prognosis of anti-MDA5+ DM patients, and the intensification of IST does harm to the SPM prognosis.

Clinicopathological and oncological outcomes in upper extremity Ewing's sarcoma: A single institutional experience

BackgroundEwing's sarcoma is highly aggressive bone tumor having predilection for younger age groups with t (11,22) translocation, recombines the FLI-1 and EWS genes on chromosome 22. This disease requires multi-disciplinary treatment withneo-adjuvant chemotherapy followed by surgery or radiotherapy and adjuvant chemotherapy. This study was aimed to assess the demographic distribution, clinical behaviour and oncological outcome of Ewings Sarcoma involving upper extremity. MethodsFrom 2015 to 2022, 45 patients of upper extremity Ewing's sarcoma underwent treatment at a territory cancer centre. A total of 26 patients treated with surgical management were included in the study comprising 15 males (57.7 %) and 11 females (42.3 %). Mean age of presentation was 26 years (3–43 years). The most common site for Ewings sarcoma of upper extremity was Humerus(42 %) followed by Scapula(27 %), Radius(15 %), Ulna(8 %), Metacarpals(4 %) and Clavicle(4 %). Out of 26 cases, 19 (73%) underwent limb salvage surgery and 7 (27%) underwent ampuation surgery. ResultsIn limb salvage group reconstruction with Extra-corporeal radiotherapy (ECRT), Ulna centralization, Megaprosthesis and 3D printed scapula was performed following wide resection of tumor. In Amputation group ray resection in one case and forequarter amputation was performed in six cases. Mean serum LDH value was 335 IU/L (2.3X Normal value) and serum albumin was 4.04 gm/dl. Mean tumour necrosis after neo-adjuvant chemotherapy was 68 %. Out of 26 cases, 19(73 %) cases underwent limb salvage and 7 patients underwent amputation surgery. Out of 26, 13 (50 %) patients developed metastasis on follow up. The Event free survival (EFS) in current study was 70 % at 12 months and 40 % at 24 months. Mean Event free survival (EFS) in current study was 33.5 months (22.3–44.6) and Median Event free survival (EFS) in current study was 25 months (19.7–30.2). ConclusionThis study characterises demographic and oncologic outcomes of upper extremity ewings sarcoma in Indian subpopulation. Pain and swelling were prominent clinical findings at presentation in patients with upper extremity Ewing's sarcoma. The survival rate following limb salvage surgery in Ewings sarcoma of upper extremity was comparable to that of patients with amputation surgery. Ewings sarcoma of upper extremity was associated with higher LDH level which was raised more than twice the normal range and can led to worse oncologic outcomes. A comparative study on upper extremity and lower extremity ewings sarcoma will be of help to improve literature on this rare disease.

Using underwater currents as an occupational enrichment method to improve the stress status in rainbow trout.

This study investigated the effects of occupational enrichment, specifically underwater currents, on the stress status of rainbow trout (Oncorhynchus mykiss). A total of 540 fish were divided into three groups: control tanks without artificial currents (CO), tanks with randomly fired underwater currents (RFC), and tanks with continuous current throughout the day (CT). After 30days, half of the fish in each group underwent a 5-day pre-slaughter fasting (5D), while the others were fed until the day before slaughter (0D). Fish in the RFC group exhibited lower levels of plasma cortisol and acetylcholinesterase enzyme activity in hypothalamus and optic tract than other groups, suggesting an improved stress status. RFC group also showed higher levels of non-esterified fatty acids (NEFA) in 5D fish and higher liver glycogen stores, suggesting improved energy reserves. In comparison, the CT group had higher LDH levels, possibly due to their increased swimming activity. The CO group had significantly lower NEFA levels at 5D compared to the RFC group, suggesting lower energy reserves. The RFC fish had darker and yellow-reddish skin and liver color, suggesting an improved stress status and lower lipid reserves, respectively. Overall, although a significant stress response was not observed in fasted individuals, possibly due to the relatively short fasting period, the study suggests that providing occupational enrichment using randomly fired underwater currents for 1month helped to improve stress status in rainbow trout, indicating that occupational enrichment during the grow-out phase can positively impact the welfare of rainbow trout during routine handling procedures.
