Durable left ventricular assist devices following temporary circulatory support on a microaxial flow pump with and without extracorporeal life support

BackgroundCirculatory support with a catheter-based microaxial flow pump (mAFP) plays a major role in the treatment of severe cardiogenic shock. In most patients who fail to recover while on temporary mechanical circulatory support (tMCS) and who are not eligible for heart transplantation, durable left ventricular assist device (dLVAD) implantation is usually considered a reliable option. This study aimed to describe the outcome of dLVAD therapy following mAFP support and to identify predictors of mortality. MethodsThis was a retrospective analysis of data from a multicenter registry on patients who underwent dLVAD implantation following tMCS with a mAFP between January 2017 and October 2022 (n = 332) from 19 European centers. ResultsPatients were supported with an Impella 5.5 (n = 92), 5.0 (n = 153) or CP (n = 87) and were transitioned to a HeartWare HVAD (n = 128) or Heartmate 3 (n = 204) during the same period. One hundred and twenty-five patients (39.2%) also required extracorporeal life support before and/or during mAFP therapy. The 30-day and 1-year survival were 87.8% and 71.1%, respectively. The following risk factors for 1-year mortality were identified: age (odds ratio [OR], 1.02), specifically age over 55 years (OR, 1.09), body mass index >30 kg/m2 (OR, 2.2), female sex (OR for male sex, 0.43), elevated total bilirubin (OR, 1.12), and low platelet count (OR, 0.996). ConclusionsBased on the identified risk factors, a risk score for estimating 1-year mortality was calculated to optimize patient selection for dLVAD implantation.

Risk factors associated with dengue complications and death: A cohort study in Peru.

Dengue has emerged as an unprecedented epidemic in Peru, and it is anticipated that this issue will escalate further owing to climate change. This study aimed to determine the risk factors associated with death from dengue in patients treated at Hospital II in Pucallpa, Peru. This retrospective cohort study collected information from the medical records of patients with a diagnosis of dengue treated at Hospital II Pucallpa-Peru between January 2019 and March 2023. The primary outcome was death, and the secondary outcome was death, development of severe dengue, or Intensive Care Unit (ICU) admission. Cox regression models were used to determine risk factors. The clinical records of 152 patients were evaluated, with a median age of 27.5 years (interquartile range, 11-45). Among all patients, 29 (19.1%) developed severe dengue, 31 (20.4%) were admitted to the ICU, and 13 (8.6%) died during follow-up. In the survival analysis, bilirubin >1.2 mg/dL was associated with a higher risk of death aHR: 11.38 (95% CI: 1.2 106.8). Additionally, factors associated with poor prognosis included having 1 to 3 comorbidities aRR: 1.92 (1.2 to 3.2), AST ≥251 U/L aRR: 6.79 (2.2 to 21.4), history of previous dengue aRR: 1.84 (1.0 to 3.3), and fibrinogen ≥400 mg/dL aRR: 2.23 (1.2 to 4.1). Elevated bilirubin was associated with death from dengue, whereas an increase in comorbidities and a history of previous dengue were related to a poor prognosis of the disease. Early identification of severe dengue would be more feasible with improved access to laboratory testing, particularly in tropical areas with a high dengue incidence.

Effect of Lactiplantibacillus plantarum on the growth, hemato-biochemical, inflammation, apoptosis, oxidative stress markers, involved gens and histopathological alterations in growing rabbits challenged with aflatoxin B1

Aflatoxin B1 (AFB1) is a significant pollutant found in food and feed, posing a threat to public health. The objective of this study was to assess the effect of Lactiplantibacillus plantarum (LACP) against AFB1 in growing rabbits by investigating growth, serum metabolites, immunity, antioxidant capacity, and inflammatory response. A total of 60 growing male rabbits (721.5 ± 2.68g) were allocated to 4 experimental groups. The control group receiving only a basal diet, the AFB1 group (0.3 mg AFB1/kg diet), the LACP group (1 × 109 cfu/g /kg diet), and the combination group (1 × 109 cfu/g + 0.3 mg AFB1/kg diet; AFB1+ LACP) for 8 wk. The administration of AFB1 alone significantly decreased the final body weight, body gain, and feed intake, while significantly increasing the feed conversion ratio (P < 0.05). A significant decline in total proteins and globulins, along with elevated levels of hepatic enzymes (AST, ALP, ALT, and GGT) and renal function markers (creatinine and uric acid), were observed in the AFB1-contaminated group (P < 0.05). Immunoglobulins (IgG and IgM) were significantly decreased, alongside a significant elevation of triglycerides, direct bilirubin, and indirect bilirubin in growing rabbits fed diets with AFB1 (P < 0.05). Supplementing the AFB1 diet with LACP restored the growth reduction, improved liver (AST, ALP, ALT, and GGT) and kidney (creatinine and uric acid) functions, and enhanced immune markers in rabbit serum (P < 0.05). Antioxidant indices (SOD, GSH, and CAT) were significantly decreased in the AFB1 group (P < 0.05). However, the addition of LACP to the AFB1-contaminated diets improved antioxidant capacity and malondialdehyde (MDA) and protein carbonylation (PC) in hepatic tissues of rabbits (P < 0.05). Serum interlukin-4 (IL-4) and interferon gamma (IFN-γ) levels were significantly increased in the AFB1 group (P < 0.05), but the addition of LACP significantly reversed this elevation. AFB1 downregulated the expression of immune-inflammatory genes such Nrf2, IL-10, and BCL-2 genes, while up-regulating the caspase-3 (CASP3) gene (P < 0.05). Supplementing AFB1 diet with LACP significantly decreased the expression of immune-inflammatory genes (Nrf2, IL-10, and BCL-2) and reduced the expression of the apoptotic-related gene CASP3. This study highlights the potential of L. plantarum (1 × 109 cfu/g /kg diet) as a protective agent against AFB1 in growing rabbits by enhancing antioxidant and immune function and reducing apoptosis and inflammation pathways.

Reasonability of Frequent Laboratory Analyses during Therapy with Nivolumab and Nivolumab+Ipilimumab in Patients with Advanced or Metastatic Renal Cell Carcinoma during the Phase 2 Clinical Trial TITAN-RCC.

In clinical trials, laboratory values are assessed with high frequency. This can be stressful for patients, resource intensive, and difficult to implement, for example in office-based settings. In the prospective, multicentre phase 2 TITAN-RCC trial (NCT02917772), we investigated how many relevant changes in laboratory values would have been missed if laboratory values had been assessed less frequently. Patients with metastatic renal cell carcinoma (n = 207) received a response-based approach with nivolumab and nivolumab+ipilimumab boosts for non-response. We simulated that laboratory values were obtained before every second dose instead of every dose of the study drug(s). We assessed elevated leukocyte counts, alanine aminotransferase, aspartate aminotransferase, bilirubin, creatinine, amylase, lipase, and thyroid-stimulating hormone. Dose delay and discontinuation criteria were defined according to the study protocol. With the reduced frequency of laboratory analyses, dose delay criteria were rarely missed: in a maximum of <0.1% (3/4382) of assessments (1% [2/207] of patients) during nivolumab monotherapy and in a maximum of 0.2% (1/465) of assessments (1% [1/132] of patients) during nivolumab+ipilimumab boosts. An exception was lipase-related dose delay which would have been missed in 0.6% (25/4204) of assessments (7% [15/207] of patients) during nivolumab monotherapy and in 0.8% (4/480) of assessments (3% [4/134] of patients) during nivolumab+ipilimumab boosts, but would have required the presence of symptoms. Discontinuation criteria would have only been missed for amylase (<0.1% [1/3965] of assessments [0.5% (1/207) of patients] during nivolumab monotherapy, none during nivolumab+ipilimumab boosts) and lipase (0.1% [5/4204] of assessments [2% (4/207) of patients] during nivolumab monotherapy; 0.2% [1/480] of assessments [0.7% (1/134) of patients] during nivolumab+ipilimumab boosts). However, only symptomatic patients would have had to discontinue treatment due to amylase or lipase laboratory values. In conclusion, a reduced frequency of laboratory testing appears to be acceptable in asymptomatic patients with metastatic renal cell carcinoma treated with nivolumab or nivolumab+ipilimumab.

Gram-negative bacterial infections in surgical intensive care unit patients following abdominal surgery: high mortality associated with Stenotrophomonas maltophilia infection

BackgroundStenotrophomonas maltophilia, a multidrug-resistant gram-negative bacteria (GNB), is an emerging nosocomial pathogen. This study assessed the clinical outcomes of GNB infections in surgical intensive care unit (SICU) patients post-abdominal surgery, focusing on the differences between S. maltophilia and other GNBs, including Pseudomonas aeruginosa.MethodsA retrospective study was conducted on SICU patients at Kaohsiung Chang Gung Memorial Hospital from 2010 to 2020, who developed GNB infections following abdominal surgery.ResultsOf 442 patients, 237 had S. maltophilia and 205 had non-S. maltophilia GNB infections (including 81 with P. aeruginosa). The overall mortality rate was 44.5%, and S. maltophilia infection emerged as a significant contributor to the mortality rate in patients with GNB infections. S. maltophilia patients had longer mechanical ventilation and SICU stays, with a 30-day mortality rate of 35.4%, higher than the non-S. maltophilia GNB (22.9%) and P. aeruginosa (21%) groups. In-hospital mortality was also higher in the S. maltophilia group (53.2%) compared to the non-S. maltophilia GNB (34.6%) and P. aeruginosa groups (29.6%). Risk factors for acquiring S. maltophilia included a higher Sequential Organ Failure Assessment score and prior broad-spectrum antibiotics use. Older age, polymicrobial infections, and elevated bilirubin were associated with increased 30-day mortality in S. maltophilia patients.ConclusionS. maltophilia infections in post-abdominal surgery patients are linked to higher mortality than non-S. maltophilia GNB and P. aeruginosa infections, emphasizing the need for early diagnosis and treatment to improve outcomes.

Anaplasmosis concurrent with copper deficiency in a Salem Black kid

Four months old Salem black kid was brought with the history of alopecia around the face and ear. Clinical examination revealed severe alopecia on ears, face, trunk and easy epilation of hairs along with depigmentation, mild scaling in ear margins, steely appearance, pale mucosa and loss of body condition. Detailed dermatological analysis like skin scrapings and trichogram revealed negative for ectoparasites and hair growth abnormalities. Blood smear examination revealed Anaplasma ovis organisms, with blood picture of normochromic microcytic anemia. Amplified Polymerase chain reaction product found to be positive for Anaplasma ovis. Serum biochemistry revealed low level of copper (0.0598 mg/L), elevated total bilirubin (3.6 mg/dl), direct bilirubin (2.83 mg/dl), creatinine kinase (73 mg/dl) and LDH (348 U/L). Based on above findings and treatment response, the case was diagnosed as anaplasmosis in a kid with concurrent copper deficiency.

Histopathological impact of SARS-CoV-2 on the liver: Cellular damage and long-term complications.

Coronavirus disease 2019 (COVID-19), caused by the highly pathogenic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), primarily impacts the respiratory tract and can lead to severe outcomes such as acute respiratory distress syndrome, multiple organ failure, and death. Despite extensive studies on the pathogenicity of SARS-CoV-2, its impact on the hepatobiliary system remains unclear. While liver injury is commonly indicated by reduced albumin and elevated bilirubin and transaminase levels, the exact source of this damage is not fully understood. Proposed mechanisms for injury include direct cytotoxicity, collateral damage from inflammation, drug-induced liver injury, and ischemia/hypoxia. However, evidence often relies on blood tests with liver enzyme abnormalities. In this comprehensive review, we focused solely on the different histopathological manifestations of liver injury in COVID-19 patients, drawing from liver biopsies, complete autopsies, and in vitro liver analyses. We present evidence of the direct impact of SARS-CoV-2 on the liver, substantiated by in vitro observations of viral entry mechanisms and the actual presence of viral particles in liver samples resulting in a variety of cellular changes, including mitochondrial swelling, endoplasmic reticulum dilatation, and hepatocyte apoptosis. Additionally, we describe the diverse liver pathology observed during COVID-19 infection, encompassing necrosis, steatosis, cholestasis, and lobular inflammation. We also discuss the emergence of long-term complications, notably COVID-19-related secondary sclerosing cholangitis. Recognizing the histopathological liver changes occurring during COVID-19 infection is pivotal for improving patient recovery and guiding decision-making.

CLINICAL AND LABORATORY PROFILE OF ADMITTED PATIENTS PRESENTING WITH FEBRILE ILLNESS DUE TO DENGUE AND SCRUB TYPHUS COINFECTION FROM A TERTIARY CARE HOSPITAL IN SOUTH RAJASTHAN, INDIA

Objective: The present study aims at describing the clinical features, laboratory diagnosis, and complications in patients presenting with febrile illness due to scrub typhus and dengue coinfection from Southern Rajasthan, India. Method: This present prospective, observational, and hospital-based study conducted in the Department of Microbiology of AIMS &amp; RC, Rajsamand, located in Southern Rajasthan, from January 2021 to December 2021. Scrub typhus was diagnosed in the microbiology laboratory by performing SD Bioline, one-step scrub typhus for the detection of IgM antibody, and dengue fever using J.mitra and Co. Pvt. Ltd., rapid card test for the detection of NS1 antigen and IgM antibody. Result: Out of 500 patients suspected of AUFI, 25 (5%) patients diagnosed of having dengue and scrub typhus coinfection. Fever was present in all 25 (100%) patients and 13 (52%) of patients had arthralgia, nausea, and vomiting. The most common sign noticed in our study was pallor and icterus in 10 (40%) patients each followed by shock/hypotension in 8 (32%) and hepatosplenomegaly in 5 (20%). The most predominant laboratory finding was thrombocytopenia (&lt;1.0 × 106/cumm) in 23 (92%) patients, while elevated bilirubin (&gt;2 mg/dl) in 22 (88%) and elevated transaminase and prolonged aPTT in 21 (84%) patients each. The majority of patients 23 (92%) had hepatic dysfunction, i.e., in followed by multi-organ dysfunction (MODS) in 15 (60%). Conclusion: In developing countries like India, particularly in tropical areas, dengue, and scrub typhus coinfection is under-recognized entity. Additional investigation should be carried out in cases of AUFI patients with features such as hypotension, leukocytosis, early drop in platelet counts, and hypoalbuminemia.

Engraftment Syndrome in Autologous Hematopoietic Stem Cell Transplant Patients: Incidence, Associated Risk Factors, Features, and Outcomes.

BACKGROUND Autologous stem cell transplantation (ASCT) is the standard treatment for multiple myeloma (MM) and refractory/relapsed (R/R) lymphoma patients. Engraftment syndrome (ES) is a non-infectious febrile syndrome during ASCT. This study focused on the incidence, risk factors, manifestations, and outcomes of patients with ES receiving ASCT. MATERIAL AND METHODS This retrospective cohort study included MM and R/R lymphoma patients who underwent ASCT at Chiang Mai University Hospital from January 2014 to September 2020. ES was diagnosed by the consensus of independent reviewers based on clinical manifestations, laboratory, and radiological findings. RESULTS We included 124 patients, of whom 67 (54.1%) had lymphoma. The mean age was 48.0±12.3 years. The incidence of ES was 36.3%. The ES group had a significantly higher proportion of patients with fever, elevated liver enzymes, elevated bilirubin, hypoalbuminemia, and weight gain compared to the non-ES group. TNC more than 10×10⁸ cells/kg was an independent risk factor for ES (odds ratio 2.94 with a 95% confidence interval of 1.15-7.50, P=0.024). ES was associated with longer length of stay (22.5±8.2 vs 16.9±6.4 days, P<0.001) but was not associated with overall survival (OS). CONCLUSIONS The incidence of ES in this cohort was 36.3%. Features observed in ES patients were fever, elevated liver enzymes, elevated bilirubin, and hypoalbuminemia. TNC of more than 10×10⁸ cells/kg was an independent risk factor. ES was associated with longer length of stay but not survival outcomes.

Phase II study to evaluate safety and efficacy of neratinib, an irreversible pan-HER tyrosine kinase inhibitor, and trastuzumab biosimilar in patients with HER2 mutated advanced solid tumors (KCSG AL20-17).

3134 Background: Neratinib, an irreversible pan-HER tyrosine kinase inhibitor, has single agent clinical activity in HER2 mutated cancer. This open-label single arm phase 2 trial investigated the efficacy and safety of the dual anti-HER2 therapy, neratinib plus trastuzumab in heavily pretreated patients with HER2 mutated solid tumors excluding HER2 amplifications. Methods: Neratinib was administered 240mg p.o. daily with trastuzumab biosimilar (Herzuma) every 3 weeks. The primary endpoint was objective response rate (ORR) by RECIST v1.1. Secondary endpoints were duration of response (DoR), progression free survival (PFS), and safety. An exploratory biomarker study was also conducted. Results: Forty patients were enrolled with a median follow-up of 11.08 months (range, 0.39-21.63 months) and a median of 3 (range 1-9) lines of prior systemic therapy. Tumor types included lung (42.5%), colorectal (20%) biliary (12.5%), and breast (7.5%). Sixty percent (60%) of patients (n=24) had HER2 mutation in the kinase domain. Among evaluable patients (n=39), the ORR was 23.1% (CR=0, PR=9) with a median DoR of 11.18 months (95% CI 0-22.63). Median PFS was 3.42 months (95% CI 1.57-5.27) and median overall survival was 9.47 months (95% CI 2.93-16.01). Grade ≥3 adverse events (AEs) occurred in 47.5% of patients (n=19) and diarrhea was the most frequently reported AE (n=10; 25%) followed by bilirubin elevation (n=2; 5%), and anemia (n=2; 5%). Conclusions: In heavily pretreated patients with HER2 mutated solid tumors, neratinib plus trastuzumab showed a moderate response rate, with a durable duration of response. Most AEs were manageable, highlighting the need for prophylactic diarrhea management. Exploratory biomarker results will be presented at the upcoming meeting.

Preliminary results from a phase I expansion study of ZG005, a bispecific antibody targeting TIGIT and PD-1, as monotherapy in patients with advanced solid tumors.

2611 Background: ZG005, a PD-1 and TIGIT dual-specific antibody, is a promising immunotherapy for tumors as blocking these two pathways could synergistically activate T cells and enhance the anti-tumor activity of NK cells. Partial results from the dose-escalation stage of this first-in-human (FIH) study were revealed at ASCO 2023, and here we present the preliminary results from the dose-expansion stage. Methods: After a dose-escalation stage, patients (subjects) with solid advanced tumors were enrolled into this dose-expansion stage. Subjects in each cohort were randomized 1:1 to receive ZG005 treatment of either RP2D from the dose-escalation stage (10 mg/kg Q3W or 20 mg/kg Q3W) by intravenous infusion. Efficacy was assessed primarily according to RECIST v1.1. Results: The dose-escalation stage was completed with 32 subjects enrolled and the dose-expansion stage is currently ongoing. As of December 25, 2023, a total of 68 subjects were treated with ZG005 as monotherapy, including 33 males (median age 60) and 35 females (median age 58), wherein 33 had received PD-1/PD-L1 inhibitors before enrollment. Three subjects with either pancreatic neuroendocrine cancer, intrahepatic cholangiocarcinoma, or cervical cancer were treated for more than 20 cycles. The subject with cervical cancer maintained PR status for more than 35 weeks. A total of 1 CR, 6 PR, and 28 SD cases were reported from the 57 efficacy evaluable subjects, among them 1 CR, 5 PRs, and 8 SDs from the 17 subjects with cervical cancer. A total of 43 TRAEs (43/68, 63.2%) were reported, of which 6 were ≥ grade 3, including 2 liver function abnormalities, 1 elevated γ-glutamyl- transferase, 1 unknown death, 1 hypertriglyceridemia and lipase elevation, and 1 elevation in both aspartate aminotransferase and blood bilirubin. SAEs occurred in 19 subjects, 3 events were related to ZG005, including 2 liver function abnormalities (1 was a DLT event), and 1 unknown death. The death event occurred in one female, who received only one dose of ZG005, and the cause of her death was most likely due to poor underlying condition. The Cmax and AUC increased approximately in dose proportion. Conclusions: ZG005 has demonstrated a tolerable safety profile and encouraging anti-tumor activity during the FIH study. Expansion cohorts in specific advanced solid tumors are underway to warrant further development. Clinical trial information: CTR20220021.

Preliminary data of a phase Ib/II trial evaluating the efficacy and safety of adebrelimab, camrelizumab plus apatinib as first-line therapy in patients with advanced hepatocellular carcinoma.

e16221 Background: The CARES-310 study has demonstrated that the combination of the anti-PD-1 antibody camrelizumab and the VEGFR2 tyrosine kinase inhibitor apatinib exhibits improved progression-free survival (PFS) and overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC). We conducted this study to investigate whether the addition of the anti-PD-L1 antibody adebrelimab to camrelizumab and apatinib would further improve clinical outcomes. Methods: This is a prospective, phase 1b/2 clinical trial employing the i3 + 3 dose escalation design. Eligibility includes adults with unresectable or metastatic HCC, a ECOG PS of 0 or 1, a Child-Pugh score ≤ 7, and at least one measurable lesion per RECIST v 1.1. In phase 1b, patients (pts) received adebrelimab (10 mg/kg or 20 mg/kg, I.V., D1, Q3W), camrelizumab (200mg, I.V., D1, Q3W), and apatinib (250 mg orally daily). Phase 2 is a single arm, open-label trial in the first-line setting. The primary objective were dose-limiting toxicity (DLT), maximal tolerated dose (MTD), and recommended phase II dose (RP2D). With α = 0.05 and 80% power, the pts needed for stage I and total of the Simon 2-stage design was 17 and 41 pts, respectively. Results: As of 4 February 2024, 6 HCC pts progressed after or were intolerant to first-line treatment (systemic therapy ± surgical resection) were treated in 1 dose cohorts. 1 DLT occurred (Grade 3 elevated blood bilirubin increased). The RP2D was adebrelimab (10 mg/kg), camrelizumab (200mg), and apatinib (250 mg). The most common drug-related AEs were Hypertension (83.3%) and Rash (50%); and Serum amylase increased, Itching, ALT/AST increased, and Hypothyroidism (each 33.3%). Immune-related AEs were similar to those seen with other checkpoint blockade agents. No drug-related AEs led to death. 1 pts (16.7%) discontinued due to drug-related AEs. Conclusions: The combination of Adebelimumab, Camrelizumab, and Apatinib demonstrated manageable safety for unresectable HCC. Enrollment in the phase II trial is ongoing and updated clinical data will be presented. Clinical trial information: NCT05924997 .

A retrospective study of PD-1/PD-L1 combination therapy versus TKI monotherapy in elderly patients with uHCC.

e16191 Background: The rising elderly population worldwide has led to an increase in cases of liver cancer among individuals aged ≥65 years. With the advancement of medical treatments, the management of unresectable hepatocellular carcinoma (uHCC) now predominantly involves immunotherapy combination therapy. However, existing data in elderly patients are limited. Therefore, we conducted a retrospective analysis on the efficacy and safety of immune combination therapy compared with TKI monotherapy in elderly uHCC patients. Methods: A retrospective analysis was conducted on uHCC patients aged ≥65 years at the First Hospital of Jilin University between March 2019 and July 2023. The targeted therapy used in this study included, but not limited to, sorafenib, lenvatinib. PD-1/PD-L1 inhibitors such as pembrolizumab and atezolizumab were also utilized. Follow-up was conducted until death, loss to follow-up, or December 2023. The primary endpoint was overall survival (OS), while the secondary endpoints were progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), adverse events (AEs) and immune-related AEs (irAEs). Results: A total of 70 patients were included in this study, with 33 patients receiving monotherapy, and 37 patients receiving immune combination therapy. The median age was 68 years old, with 78.8% being male. The combination therapy group had a higher ORR (10.8% vs. 3.0%) DCR (48.5% vs. 45.9%) compared to the monotherapy group. However, there were no statistically significant differences in median PFS (7.0 vs. 12.0 months) and median OS (9.8 vs. 17.5 months) between the two groups. Among the subgroups, combination therapy showed better results except for patients with ascites. Immune combination therapy appeared to be superior to monotherapy in terms of both PFS (6.2 vs. 6.8 months, P = 0.888) and OS (6.8 vs. 10.2 months, P = 0.888). Multivariate analysis showed that elevated total bilirubin may be a risk factor for OS in patients ≥65 years old. Regarding safety, the adverse event (AE) rate was 39.3% in the monotherapy group. The most common AEs reported were abdominal distension (18.2%), fatigue (15.2%), and proteinuria (6.1%). In the combination therapy group, the AE rate was higher at 59.4%, with the most common AEs being thyroid function abnormalities (24.3%), fatigue(24.3%), decreased appetite(18.9%), and hypertension(18.9%). The rate of drug withdrawal due to adverse reactions was significantly higher in patients receiving combination therapy compared to those receiving monotherapy (40.5% vs. 12.1%, P = 0.008). Conclusions: In elderly uHCC patients (≥65 years old), immune combination therapy shows a higher ORR and potentially longer PFS and OS except patients with ascites. AEs and drug withdrawal rates are higher in the combination therapy group. Further discussions are needed to determine the optimal treatment strategy for elderly uHCC patients.

Correlation between gestational age and incidence of hyperbilirubinemia in neonates

The incidence of hyperbilirubinemia in neonates is a significant concern worldwide, with potential implications for morbidity and mortality. This study aims to investigate the correlation between gestational age and the occurrence of hyperbilirubinemia in neonates. Secondary data were collected from the Neonatal Intensive Care Unit of Buleleng Regional Hospital from October 2022 to March 2024. The study employed an observational-analytical design with a cross-sectional approach. Pearson correlation analysis examined the relationship between bilirubin levels and gestational age. The results revealed a negative linear correlation between neonatal bilirubin levels and gestational age, indicating a higher risk of elevated bilirubin levels in preterm neonates. The majority of neonates included in the study were preterm (72.3%), with 98.3% experiencing hyperbilirubinemia. This study contributes valuable insights into the relationship between gestational age and hyperbilirubinemia in neonates, particularly in resource-limited settings. Early identification of at-risk neonates and appropriate interventions are crucial for preventing complications associated with hyperbilirubinemia.

Cisplatin monotherapy as a treatment option for patients with HER-2–negative breast cancer facing hepatic visceral crisis or impending visceral crisis: A single-center cohort study.

e13057 Background: The international consensus guidelines, ESO-ESMO's fifth edition, characterize visceral crisis (VC) in advanced breast cancer (ABC) as a swift rise in bilirubin during disease progression. The guidelines also briefly address the impending VC (IVC) definition. Systemic treatment data for hepatic VC/IVC are scarce and lacking in international guidelines regarding BC treatment. This study explores cisplatin monotherapy's safety and efficacy in HER2-negative BC patients with hepatic IVC/VC. Methods: In this retrospective cohort study conducted at a Reference Cancer Center in Southern Poland, data from HER2 negative ABC patients who underwent cisplatin monotherapy (60-80mg/m2, every 3-4 weeks) between 2016 and 2023 were examined. Hepatic VC followed ABC5 definition of rapid bilirubin elevation &gt;1.5 times the upper limit of normal (ULN) due to diffuse liver metastases, in the absence of biliary tract obstruction or Gilbert's syndrome; IVC was characterized by rapid, symptomatic liver progression, a majority of liver involvement, with ALT or AST &gt;2 x ULN, and significant increases in LDH, alkaline phosphatase, or GGTP. Results: The study included 33 female participants (24 hormonal positive) with a mean age of 53.8 years (range 34-77). Among them, 10 were identified with hepatic VC, and 23 with IVC. Median number of previous palliative systemic treatment lines was 2 (range: 0-5). The median progression-free survival was 1.87 months and the median overall survival was 2.67 months. Patients received median 1 cycle of cisplatin (1-6): 17 patients received only one cycle, 6 patients two cycles and 10 patients ≥three cycles. Using the Conditional Inference Trees algorithm allowed to assess that patients with performance status (PS) 0 or 1 (15 patients) had a 66.67% chance of achieving stable disease (SD) or partial regression (PR) as the best response, while patients with PS ≥2 (18 patients) had a 5.6% chance of achieving SD or PR as per Response Evaluation in Solid Tumors 1.1 Criteria (median time from cisplatin initiation to imaging studies 2.23 months). Eight patients experienced adverse events of grade ≥3, such as fatigue or nephrotoxicity leading to dose reduction in 5 cases and treatment discontinuation in 2. Conclusions: The differentiation between IVC and VC lacks precision. Due to the hepatotoxicity of BC-active drugs, specific recommendations for systemic treatment are lacking. Our study explored cisplatin's potential use, finding it to be a feasible choice in patients with PS ≤1 experiencing hepatic IVC/VC, regardless of liver function parameters. Almost one-third of our patients were administered treatment in the last 30 days of life, potentially adversely affecting their quality of life and causing unwarranted suffering and costs. Academic clinical trials should be organized to address this pressing medical gap.

A pediatric case of Burkitt’s lymphoma with bile duct obstruction requiring surgical biliary reconstruction

BackgroundBiliary obstruction due to compression by a B-cell solid tumor occurs rarely. A few reports have described biliary reconstruction surgery for obstructive jaundice caused by Burkitt’s lymphoma. However, there are no detailed reports on pediatric cases. We report a pediatric case of obstructive jaundice due to malignant lymphoma treated with biliary reconstruction surgery.Case presentationA 5-year-old girl presented to our hospital with a massive abdominal tumor that caused biliary stricture. Chemotherapy was initiated after an open tumor biopsy. However, endoscopic biliary stent placement was performed owing to elevated bilirubin levels. We treated the patient with chemotherapy for 9 months while endoscopically replacing the biliary stent every few months. She achieved complete tumor remission. However, sclerotic lymph nodes were persistent on the dorsal side of the cholecystic duct junction, and biliary stricture at the same site had changed to stent-dependent biliary obstruction. Therefore, we performed choledochojejunostomy and retrocolic Roux-en-Y reconstruction 15 months after initial admission. There were no postoperative complications or tumor recurrences, and the bilirubin level remained low. Histopathologically, the resected bile duct wall was fibrotic and thick, and the bile duct lumen narrowed.ConclusionsBiliary reconstruction is effective to achieve long-term biliary patency in pediatric patients with stent-dependent biliary obstruction due to malignant lymphoma. However, the decision on when to stop biliary stent replacement and proceed to biliary reconstruction surgery is a matter of debate. Further case studies are required to address this issue.

Lung Manifestation of Dengue Fever: A Retrospective Study.

Introduction Dengue fever, caused by the dengue virus transmitted by Aedes aegypti mosquitoes, is a significant public health concern globally. Its resurgence in recent years, particularly in low- and middle-income countries, has led to increased morbidity and mortality rates. Atypical manifestations, involving the cardiac, liver, gut, renal, blood, bone, nervous, and respiratory systems, in dengue, can complicate both diagnosis and management. This study aimed to investigate the incidence of lung manifestations in dengue-infected individuals and their correlation with patient outcomes. Background The prevalence of dengue fever has risen dramatically over the past two decades, with Asia bearing the brunt of the burden, particularly India. The pathophysiology of lung complications in dengue remains unclear but is thought to be related to capillary leak syndrome and thrombocytopenia. Studies suggest that respiratory symptoms may be associated with severe cases and increased mortality rates. Despite limited research in India, understanding lung manifestations in dengue is crucial for improving diagnostic accuracy and patient care. Methods A retrospective study was conducted at K.S. Hegde Hospital, a tertiary care facility located in Mangalore, India, involving patients aged 18 years and above diagnosed with dengue fever between January and December 2019. Data gathered comprised patient demographics, clinical symptoms, laboratory findings, imaging results including radiographs, computed tomography (CT) scans of the chest (if accessible), ultrasound examinations of the chest and abdomen, and 2D echocardiograms, as well as patient outcomes. Diagnosis of lung manifestation was established through clinical assessment, chest X-ray interpretation, and ultrasound of the chest. Statistical analysis was conducted using SPSS Statistics (version 20), with a significance set at p<0.05. Results Out of 255 dengue cases, 10.19% (n=26) exhibited pulmonary manifestations, with pleural effusion being the most common. Older age (>50 years) and comorbidities were associated with a higher incidence of lung involvement. Respiratory symptoms, such as breathlessness, were more prevalent in patients with pulmonary complications. Laboratory parameters indicated distinct profiles in patients with lung manifestations, including elevated total count, urea, bilirubin, and liver enzymes, and reduced platelet counts. Mortality rates were higher in patients with lung involvement, older age, and comorbidities. Discussion The study findings highlight the importance of recognizing respiratory symptoms in dengue fever, particularly in older patients and those with underlying health conditions. The association between pulmonary involvement and adverse outcomes underscores the need for early detection and appropriate management strategies. Future research should focus on elucidating the pathophysiology of lung complications in dengue and developing targeted interventions to improve patient outcomes. Conclusion Lung manifestations in dengue fever represent a significant clinical challenge and are associated with increased morbidity and mortality. Early recognition of respiratory symptoms, along with prompt diagnostic evaluation and appropriate management, is essential for improving patient prognosis. Further studies are warranted to deepen our understanding of lung involvement in dengue and optimize therapeutic approaches to mitigate its impact on patient outcomes.

Vincamine alleviates intrahepatic cholestasis in rats through modulation of NF-kB/PDGF/klf6/PPARγ and PI3K/Akt pathways

The defect in the hepatobiliary transport system results in an impairment of bile flow, leading to accumulation of toxic compounds with subsequent liver disorders. Vincamine, a plant indole alkaloid that is utilized as a dietary supplement, has been known for its promising pharmacological activities. For the first time, the present study was planned to estimate, at the molecular level, the potentiality of vincamine against alfa-naphthyl isothiocyanate (ANIT)-induced hepatic cholestasis. Liver function tests were analyzed. Hepatic activity of SOD and levels of GSH and MDA were assessed. Hepatic contents of bax, bcl2, NF-kB, PPARγ, catalase, heme-oxygenase-1, NTCP, and BSEP were evaluated using ELISA. mRNA levels of NF-kB, IL-1β, IL-6, TNFα, PDGF, klf6, PPARγ, and P53 were examined using qRT-PCR. PI3K, Akt and cleaved caspase-3 proteins were assessed using western blotting. Histopathological analyses were performed using hematoxylin & eosin staining. ANIT-induced hepatic cholestasis elevated liver function tests, including AST, ALT, GGT, ALP, and total bilirubin. ANIT reduced the protein expression of NTCP and BSEP hepatic transporters. It induced the expression of the inflammatory genes, TNFα, IL-6, IL-1β, and PDGF, and the expression of NF-kB at the genetic and protein level and suppressed the anti-inflammatory genes, klf6 and PPARγ. Also, antioxidant markers were reduced during ANIT induction such as GSH, SOD, catalase, heme-oxygenase-1 and PI3K/Akt pathway, while MDA levels were elevated. Furthermore, the expression of P53 gene, bax and cleaved caspase 3 proteins were activated, while bcl2 was inhibited. Also, the histopathological analysis showed degeneration of hepatocytes and inflammatory cellular infiltrates. However, vincamine treatment modulated all these markers. It improved liver function tests. It inhibited the expression of NF-kB, TNFα, IL-6, IL-1β and PDGF and activated the expression of klf6 and PPARγ. Furthermore, vincamine reduced MDA levels and induced GSH, SOD, catalase, heme-oxygenase-1 and PI3K/Akt pathway. Additionally, it inhibited expression of P53 gene, bax and cleaved caspase 3 proteins. More interestingly, vincamine showed better outcomes on the hepatic histopathological analysis and improved the alterations induced by ANIT. Vincamine alleviated hepatic dysfunction during ANIT-induced intrahepatic cholestasis through its anti-inflammatory and antioxidant efficacies by the modulation of NF-kB/PDGF/klf6/PPARγ and PI3K/Akt pathways.

Evaluating the Nephroprotective and Hepato-protective Effects of Hypoestes rosea in Acetaminophen-Induced Toxicity in Albino Rats

The leaves of Hypoestes rosea are in use as traditional medicine in the Niger Delta areas in Nigeria and the Western part of Cameroun for the management of different ailments in children, such as anaemia, malaria, fever and other ailments. Regardless of its uses, scanty studies evaluating its organ protective effects exist. Therefore, this research study evaluates the nephroprotective and hepato-protective effects of Hypoestes rosea in acetaminophen-induced toxicity in Albino rats. The objectives of this research study are to evaluate the protective effect of Hypoestes rosea on the kidney and the liver of albino rats. Acetaminophen, which is frequently used as an analgesic and antipyretic drug at high doses, can be harmful to vital organs of the body, affecting the liver and kidneys. In this study, effects of an aqueous extract of Hypoestes rosea (AEHr) on liver function parameters and kidney function parameters of acetaminophen induced-toxicity in albino rats were evaluated using acute (15 days) and sub-chronic (30 days) duration of study and study group comprising of prophylactic (pre-treatment) and therapeutic (post-treatment) phases with six experimental groups in each phase. A total of 112 adult apparently healthy Albino rats weighing (180-220g) were used for this study, divided into six experimental groups of extract control (EC), negative control (NC), positive control (PC), AEHr100mg/kg b w., AEHr 200mg/kg b w., and AEHr 300mg/kg b w. groups each of six rats. At the end of the research study period, blood samples were collected through jugular puncture for liver and kidney function parameters. Results showed that acetaminophen-induced toxicity in albino rats caused toxicity to the kidney and toxicity to the liver, as evidenced by the raised levels of potassium, urea, creatinine and low bicarbonate from the renal function parameters and also as evidenced by significant elevation of bilirubin and liver enzymes with a significantly low total protein and albumin levels from the liver function parameters when compared with other experimental groups. Conversely, AEHr at different concentrations in a dose-dependent pattern at the different treatment phases and different duration periods were able to repair the injury to the kidney and liver caused by acetaminophen induction to normal. Consequently, the findings of this research propose that Hypoestes rosea contains active ingredients accountable for the nephroprotective and hepato-protective abilities in rats and can be recommended for more studies using higher mammals.

Clinical features of individuals with laboratory values suggestive of advanced liver fibrosis when first treated for alcohol use disorder.

Effective screening for alcohol-associated liver disease is relevant in the context of chronic, excessive alcohol consumption. Patients with alcohol-associated liver disease are often not diagnosed until their liver disease is decompensated. We analyzed the prevalence and associations of Fibrosis-4 index (FIB-4) values suggestive of advanced liver fibrosis in patients referred for their first treatment of alcohol use disorder (AUD). We conducted a cross-sectional, multicenter study of noncirrhotic individuals referred for their first AUD treatment between March 2013 and April 2021. We obtained sociodemographic data, substance use characteristics, and blood samples at admission. We considered a FIB-4 value ≥2.67 suggestive of advanced liver fibrosis and used logistic regression analyses to identify features associated with this value. We included 604 patients (67% male), with a median age at admission of 48 years [IQR: 41-56 years]. The median duration of regular alcohol consumption was 21 years [IQR: 18-30 years] and the median alcohol consumption was 105 standard drink units (SDU)/week [IQR: 63-160 SDU/week]. A FIB-4 value ≥ 2.67 was present in 19.3% of cases. These patients reported more frequent binge drinking (75.4% vs. 66%, p = 0.05) than those with FIB-4 values below 2.67. In multivariate analysis, a history of binge drinking (OR 1.9, 95% CI, 1.05-3.47), anemia (OR 2.95, 95% CI, 1.42-6.11), leukopenia (OR 7.46, 95% CI, 2.07-26.8), and total serum bilirubin >1 mg/dL (OR 6.46, 95% CI, 3.57-11.7) were independently associated with FIB-4 values ≥2.67. One in five patients admitted to treatment for AUD without evidence of decompensated liver disease have FIB-4 values suggestive of advanced liver fibrosis. The presence of a binge drinking history, anemia, leukopenia, and elevated bilirubin levels is associated with high FIB-4 values.
