Comparison of biosimilar filgrastim and originator filgrastim for peripheral blood stem cell mobilization for allogeneic hematopoietic stem cell transplantation.

BACKGROUND: Nivestym, a biosimilar granulocyte colony-stimulating factor (G-CSF) to the originator filgrastim (Neupogen), is now being used for the mobilization of peripheral blood stem cells (PBSC) in allogeneic hematopoietic stem cell transplantation (allo-HSCT). We aim to compare the efficacy of Nivestym and Neupogen for PBSC mobilization in healthy allogeneic donors. METHODS: We conducted a retrospective single-center study including 541 adult allo-HSCT donors receiving Nivestym (January 2013-July 2020), or Neupogen (July 2020-June 2023) for donor PBSC mobilization. Bivariate analysis was conducted using SPSS version 28. Statistical significance was determined at a p-value <.05. RESULTS: Our study included 541 allo-HSCT donors who received Neupogen (n = 345, 64%) or Nivestym (n = 196, 36%) for PBSC mobilization. The median age was 47 years (range 17-76). The median donor weight was 86 kg (95% confidence interval [CI]: 87-91). Donors receiving Neupogen had similar pre-G-CSF white blood cell count, CD34+ percentages, and circulating CD34+ count compared with donors receiving Nivestym. The Neupogen group had similar median PBSC product total neutrophil count, CD34+ percentage, absolute CD34+ count, and infused CD34+ dose compared with the Nivestym group. For donors aged 35 years or younger, the median CD34+ dose was higher in donors who received Neupogen compared with Nivestym (6.9 vs. 6.3 million cells/kg, p = .044). CONCLUSIONS: Nivestym demonstrated similar efficacy for PBSC mobilization compared with Neupogen among allo-HSCT donors. In donors aged 35 years or younger, a slightly lower PBSC product CD34+ count was noted with Nivestym compared with Neupogen.

Tendency of Semaglutide to Induce Gastroparesis: A Case Report.

Semaglutide, an agonist of the glucagon-like peptide-1 receptor, is frequently used in the treatment of diabetes mellitus type 2, although, lately, weight loss has additionally become a reason for its use. However, if a patient is already experiencing bloating, nausea, abdominal pain, and discomfort in the abdomen, it is not recommended to use it due to concern about aggravating these symptoms. Although it is often well tolerated, there are occasions when it can have several gastrointestinal side effects. Therefore, we report a case of a patient who started taking semaglutide and later developed gastroparoresis.

Advancements in Diagnostic and Therapeutic Interventions of Non-alcoholic Fatty Liver Disease: A Literature Review.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common diseases of the liver globally. Non-alcoholic steatohepatitis (NASH) has a complicated pathophysiology which includes lipid buildup, oxidative stress, endoplasmic reticulum stress, and lipotoxicity. Recently, there has been tremendous improvement in understanding of NASH pathogenesis due to advancements in the scientific field. It is being investigated how non-invasive circulating and imaging biomarkers can help in NAFLD and NASH diagnosis and monitoring the progress. Multiple medications are now undergoing clinical trials for the treatment of NASH, and lifestyle changes have been acknowledged as one of the main treatment methods. The purpose of this review article is to discuss the incidence of NAFLD globally, management issues with NASH, and its relation to the metabolic syndrome. It explains pathophysiology as well as therapeutic strategies using natural items, dietary changes, and pharmaceutical treatments. While emphasizing the necessity for surrogate endpoints to facilitate medication development for NASH, the study also considers the potential of non-invasive imaging biomarkers including magnetic resonance imaging (MRI) and magnetic resonance elastography (MRE).

Advancements and Applications of Liquid Biopsies in Oncology: A Narrative Review.

According to the World Health Organization (WHO), nearly 10 million people died from cancer worldwide in 2020, making it the leading cause of mortality. Liquid biopsies, which provide non-invasive and real-time monitoring of tumor dynamics, have evolved into innovative diagnostic techniques in the field of oncology. Liquid biopsies offer important insights into tumor heterogeneity, treatment response, minimum residual disease identification, and personalized treatment of cancer through the analysis of circulating tumor DNA (ctDNA), circulating tumor cells (CTCs), extracellular vesicles, and microRNAs. They offer several advantages over traditional tissue biopsies, such as being less invasive, more convenient, more representative of tumor heterogeneity and dynamics, and more informative for guiding personalized treatment decisions. Liquid biopsies are being utilized increasingly in clinical oncology, particularly for patients with metastatic disease who require ongoing monitoring and treatment modification. In this narrative review article, we review the latest developments of liquid biopsy technologies, their applications and limitations, and their potential to transform diagnosis, prognosis, and management of cancer patients.

Mesalamine - A Revered Drug for Inflammatory Bowel Disease With Detrimental Effects on the Lung and Heart.

To keep inflammatory bowel disease (IBD) in remission, mesalamine is frequently utilized. It primarily targets the inflammatory response and lowers prostaglandin and leukotriene synthesis. It can be applied topically, orally, or as a suppository. It is typically well tolerated, but occasionally it can cause serious side effects, leading to a variety of medical problems. We describe two cases of severe mesalamine-induced toxicity, one of which manifested as cardiomyopathy and the other as pneumonitis. However, early detection and treatment of the side effects can be lifesaving.

Exploring the Impact of the Gut Microbiome on Obesity and Weight Loss: A Review Article.

The global obesity pandemic has prompted efforts to search for novel intervention options, including maximizing the health benefits of certain gut microbes and their metabolic byproducts. Our increased understanding of gut microbiota can potentially lead to revolutionary advancements in weight management and general well-being. We studied the association between gut microbiota and obesity, as well as the possible benefits of probiotics, prebiotics, and synbiotics in the prevention and management of obesity in this review. We observed a relationship between the metabolism of nutrients, energy consumption, and gut flora. Numerous mechanisms, including the synthesis of short-chain fatty acids, hormone stimulation, and persistent low-grade inflammation, have been postulated to explain the role of gut bacteria in the etiology of obesity. It has been discovered that the diversity and composition of the intestinal microbiome vary in response to various forms of obesity therapy, which raises concerns about the potential impact of these changes on weight loss. According to research, probiotics, prebiotics, and synbiotics may alter the release of hormones, neurotransmitters, and inflammatory factors, thereby diminishing the stimuli of food consumption that lead to weight gain. More clinical research is required to determine the optimal probiotic, prebiotic, and synbiotic supplementation dosages, formulations, and regimens for long-term weight management and to determine how different gastrointestinal microbiome bacterial species may influence weight gain.

Technology advancements have led to the development of powerful tools such as microfluidic technology, artificial intelligence, machine learning algorithms, and electrochemical biosensors to aid in early cancer detection. Non-invasive cancer screening methods like virtual colonoscopy and endoscopic ultrasonography have also been developed to provide comprehensive pictures of organs and detect cancer early. This review article provides an overview of recent advances in cancer screening in microfluidic technology, artificial intelligence, and biomarkers through a narrative literature search. Microfluidic devices enable easy handling of sub-microliter volumes and have become a promising tool for cancer detection, drug screening, and modeling angiogenesis and metastasis in cancer research. Machine learning and artificial intelligence have shown high accuracy in oncology-related diagnostic imaging, reducing the manual steps in lesion detection and providing standardized and accurate results, with potential for global standardization in areas like colon polyps, breast cancer, and primary and metastatic brain cancer. A biomarker-based cancer diagnosis is promising for early detection and effective therapy, and electrochemical biosensors integrated with nanoparticles offer multiplexing and amplification capabilities. Understanding these advanced technologies' basics, achievements, and challenges is crucial for advancing their use in oncology.

Pylephlebitis Complicated by Bacteremia: A Rare Complication Following Laparoscopic Cholecystectomy.

Pylephlebitis is a rare but serious condition caused by intra-abdominal or pelvic infections that can lead to septic thrombophlebitis of the portal veins. While laparoscopic cholecystectomy is considered a safe and effective treatment option, it is not without its risks, and pylephlebitis following this procedure is an extremely rare occurrence. Here, we present the case of a 73-year-old male who presented with lower abdominal pain for the last two weeks. He had undergone laparoscopic cholecystectomy for symptomatic cholelithiasis four weeks prior with an unremarkable follow-up. Laboratory tests revealed leukocytosis and blood culture showed Streptococcus constellatus. A CT scan revealed portal vein thrombosis causing diffuse periportal edema throughout the liver. The patient was treated with antibiotics and anticoagulation for pylephlebitis.

Role of Omega-3 Fatty Acids on Lipid Profile in Diabetic Dyslipidaemia: Single Blind, Randomised Clinical Trial.

INTRODUCTION: Diabetic dyslipidaemia is characterised by hypertriglyceridaemia, low High Density Lipoprotein (HDL), postprandial lipimea, small and dense LDL particles is considered to be a major predisposing factor for various macrovascular complications. Omega-3 fatty acids are fish oil derivative introduced in the market for dyslipidaemia associated with increased triglyceride level. AIM: To study the effect of omega-3 fatty acids on lipid profile in Type II diabetes patients. MATERIALS AND METHODS: This study was prospective, single blind, randomized comparative trial. Hundred patients were randomized into three groups. Group I received metformin 500 mg twice daily and placebo, Group II received metformin 500 mg twice daily and omega-3 fatty acids (1 gram) once daily and the Group III received metformin 500 mg twice daily and omega-3 fatty acids (1 gram) twice daily. ANOVA test was applied for analysis. RESULTS: Group II was effective in reducing the triglyceride level from 144.59±14.18 mg/dl to 101±13.31 mg/dl which was significant as compared to Group I from 147.67±18.57 mg/dl to 145.8±19.86 mg/dl respectively. Group III containing 1 g of omega-3 fatty acids twice daily showed decrease from 144.83±22.17 mg/dl to 86±17.46 mg/dl and was more effective in reducing triglyceride levels than Group II containing 1 gram of omega-3 fatty acids once daily. CONCLUSION: Omega-3 fatty acids can be given in conjunction with metformin to reduce triglyceride levels in diabetic dyslipidaemia without any adverse drug reactions or any drug interaction. Omega-3 fatty acids were effective in reducing the triglyceride level significantly as compared to placebo. Two grams of omega-3 fatty acids were more effective than 1 gram of omega-3 fatty acids in reducing triglyceride levels.

Enterobacter Meningitis and Challenges in Treatment.

Neurosurgical interventions are rarely associated with meningitis with a very low incidence rate ranging from 1.1% to 2.5%. Gram negative bacillary meningitis first described in the 1940's, previously uncommon has been increasing in the recent past associated with advanced age, immunosuppression and neurosurgery. Enterobacter meningitis though relatively uncommon is recently increasing in incidence and treatment is frequently complicated due to resistance to antibiotics making this a challenging, difficult to treat infection that may be associated with adverse clinical outcomes. Here, we describe a case of a 27-year-old patient diagnosed with brain sarcoma at the age of four years, who presented with Enterobacter meningitis following a neurosurgical intervention for resection of a recurrent brain tumor (meningioma on pathology) and had a prolonged hospital stay with a difficult to treat infection.
