OBJECTIVE: To estimate the association between oncologists' receipt of payments from the pharmaceutical industry and delivery of non-recommended or low value interventions among their patients. DESIGN: Cohort study. SETTING: Fee-for-service Medicare claims. PARTICIPANTS: Medicare beneficiaries with a diagnosis of incident cancer (new occurrence of a cancer diagnosis code in proximity to claims for cancer treatment, and no such diagnosis codes during a ≥1 year washout period) during 2014-19, who met additional requirements identifying them as at risk for one of four non-recommended or low value interventions: denosumab for castration sensitive prostate cancer, granulocyte colony stimulating factors (GCSF) for patients at low risk for neutropenic fever, nab-paclitaxel for cancers with no evidence of superiority over paclitaxel, and a branded drug in settings where a generic or biosimilar version was available...

BACKGROUND: The antibody-drug conjugates sacituzumab govitecan (SG) and enfortumab vedotin (EV) are standard monotherapies for metastatic urothelial carcinoma (mUC). Given the different targets and payloads, we evaluated the safety and efficacy of SG + EV in a phase I trial in mUC (NCT04724018). PATIENTS AND METHODS: Patients with mUC and Eastern Cooperative Oncology Group performance status ≤1 who had progressed on platinum and/or immunotherapy were enrolled...

BACKGROUND: Cytomegalovirus (CMV) reactivation is a major cause of morbidity and non-relapse mortality (NRM) in pediatric allogeneic stem cell transplantation (alloSCT) recipients. Approximately 80% of CMV seropositive recipients will experience CMV reactivation without prophylaxis. The impact of ganciclovir prophylaxis and subsequent CMV viremia on one-year survival and one-year NRM are unknown. OBJECTIVES: The primary objective was to determine the effect of CMV viremia on the probability of one-year survival and one-year NRM in pediatric alloSCT recipients receiving 100 days of ganciclovir prophylaxis...

PURPOSE: Valganciclovir (VGC) is the gold-standard for cytomegalovirus (CMV) prophylaxis (PPX) after solid organ transplant (SOT). Letermovir (LTV) was recently approved in high-risk kidney transplant and has reduced myelosuppressive toxicity. Conversion from VGC to LTV may be pursued in the setting of leukopenia. It is unknown if this strategy is effective. METHODS: Adult patients receiving abdominal SOT were included if converted from VGC to LTV between January 1, 2018 and January 31, 2023...

BACKGROUND: GCSF may improve the prognosis of severe liver disease by promoting liver regeneration and immune restoration. Our Aim was to investigate its controversial efficacy in decompensated cirrhosis, acute alcoholic hepatitis (AAH), or acute-on-chronic liver failure (ACLF) through meta-analysis. METHODS: Meta-analysis of proportions (random effect model) including 19 RCTs (1287 patients from 16 Asian and 3 European studies including 487 ACLF, 231 AAH and 569 cirrhotic patients) evaluating survival at day-28, day-90, 6 months, one year, and/or occurrence of sepsis as major outcomes...

Recently, several studies have explored inflammatory biomarkers associated with colorectal neoplasms in human plasma and investigated the prognostic value of systemic cytokine profiles and inflammatory markers in colorectal cancer. However, little is known about inflammatory biomarkers in colorectal adenoma and early cancer. We compared the level of 38 inflammatory markers in the plasma of 112 adenoma patients, 72 Tis`T1 staging of colorectal carcinoma patients, 34 T2-T4 staging of colorectal carcinoma patients and 53 normal subjects...

Ex Vivo Lung Perfusion (EVLP) can be potentially used to manipulate organs and to achieve a proper reconditioning process. During EVLP pro-inflammatory cytokines have been shown to accumulate in perfusate over time and their production is correlated with poor outcomes of the graft. Aim of the present study is to investigate the feasibility and safety of cytokine adsorption during EVLP. From July 2011 to March 2020, 54 EVLP procedures have been carried out, 21 grafts treated with an adsorption system and 33 without...

BACKGROUND: Decompensated liver cirrhosis (DC) has high mortality, but liver transplantation is limited due to organ scarcity and contraindications for transplantation. Granulocyte-colony stimulating factor (GCSF) shows potential for liver disease treatment with its regenerative and immunomodulatory properties. To assess the controversial use of GCSF in DC, a meta-analysis of randomized controlled trials (RCTs) compared survival benefits in patients receiving GCSF plus standard medical therapy (SMT) versus SMT alone...

Colony-stimulating factor 3 (CSF3) is a key factor in neutrophil production and function, and recombinant forms have been used clinically for decades to treat congenital and acquired neutropenia. Although biallelic inactivation of its receptor CSF3R is a well-established cause of severe congenital neutropenia (SCN), no corresponding Mendelian disease has been ascribed to date to CSF3. Here, we describe three patients from two families each segregating a different biallelic inactivating variant in CSF3 with SCN...

Many systemic treatments used in genitourinary oncology negatively affect haematopoiesis, thus leading to neutropenia. Neutropenic patients are vulnerable to bacterial, and other infections. Often fever is the only symptom in these patients. Neutropenic fever is a major threat for these patients, as it may lead to life-threatening therapy complications that significantly impair the patient's quality of life, Moreover, it may also worsen the prognosis due to therapy delays or necessary dose modifications. Granulocyte colony stimulating factors (GCSF), which can improve neutrophil granulocyte formation, are used both for supportive treatment in febrile neutropenia and for its prophylaxis...

Pediatric acute myeloid leukemia (AML) generally occurs de novo. The treatment of AML includes cytarabine (CYT) and other medications. The granulocyte-colony stimulating factor (GCSF) is used in the clinic in cases of neutropenia after chemotherapies. We show that the administration of GCSF in combination with CYT in AML-diagnosed mice (AML+CYT+GCSF) extended the survival of mice for additional 20 days. However, including GCSF in all treatment modalities does not affect the testis' weight or the histology of the seminiferous tubules (STs)...

The gel coagulation-spontaneous flotation (GCSF) process designed in this paper mainly rely on dissolved gas in water rather than auxiliary gas equipment to achieve spontaneous flotation. Compared with the traditional coagulation-dissolved air flotation method, GCSF has more stable flotation efficiency and shorter operation cycle under conventional hydraulic conditions. In this study, the GCSF scheme was applied for surface water treatment, and its operating efficiency, mechanism of action, and environmental implications were explored systematically...

Granulocyte colony-stimulating factor (GCSF) is a member of the hematopoietic growth factor family that acts primarily on neutrophils and neutrophilic precursors to promote cell proliferation and differentiation. Although multiple GCSF genes have been found in teleosts, knowledge of their functions during fish hematopoietic development is still limited. Here, we report for the first time the molecular and functional characterization of two goldfish GCSFs (gfGCSF-a and gfGCSF-b). The open reading frame (ORF) of the gfGCSF-a and gfGCSF-b cDNA transcript consisted respectively of 624 bp and 678 bp with its ORF encoding 207 and 225 amino acids (aa), with a 17 aa signal peptide for each gene and a conserved domain of the IL-6 superfamily...

IMPORTANCE: Premenstrual symptoms, including food cravings, are often a regular complaint among menstruating women. However, existing evidence regarding the biological mechanisms by which these food cravings occur remains unclear. Inflammation may play an essential role in the occurrence of these food cravings before menstruation. OBJECTIVE: The purpose of the present study was to examine the associations between inflammatory markers and the risk of moderate/severe food cravings while accounting for changes in hormone levels and stress across the menstrual cycle...

BACKGROUND AND PURPOSE: Administration of pegylated granulocyte-colony-stimulating factor (peg-GCSF) 24 to 72 hours after chemotherapy is usually recommended. Next-day administration (after 24 hours) resulted in fewer duration of grade (Gr) 4 chemotherapy-induced neutropenia (CIN) and decreased severity of CIN than same-day (within 4 hours). However, patients sometimes receive same-day Peg-GCSF for the sake of convenience. In addition, a few prior studies showed that the same-day method is comparable or superior to the next-day method in preventing CIN, especially in chemotherapy regimens that include day 1 myelosuppressive agents...

Background: In this study, uropathogenic Escherichia coli (UPEC) from pregnant and nonpregnant patients were characterized with respect to antimicrobial resistance (AMR) and expression of their virulence factors and cytokines elicited upon infection in urothelial (HTB-4) cells in vitro to frame proper therapeutics. Methods: Antibiotic sensitivity and adherence to HTB-4 cells were tested and PCR and real-time PCR were performed. Results: UPEC from nonpregnant patients showed the most resistance with a significant correlation between the expression of hlyA  and  TGF-β and  papC and GCSF ...

Parkinson's disease (PD) is the second most common neurodegenerative disorder and is characterized by the degeneration of the dopamine (DA) neurons in the substantia nigra pars compacta, leading to a loss of DA in the basal ganglia. The presence of aggregates of alpha-synuclein (α-synuclein) is seen as the main contributor to the pathogenesis and progression of PD. Evidence suggests that the secretome of mesenchymal stromal cells (MSC) could be a potential cell-free therapy for PD. However, to accelerate the integration of this therapy in the clinical setting, there is still the need to develop a protocol for the large-scale production of secretome under good manufacturing practices (GMP) guidelines...

Granulocyte colony-stimulating factor (GCSF) stimulates the proliferation of neutrophils but it has low serum half-life. Therefore, the present study was done to investigate the effect of XTENylation on biological activity, pharmacokinetics, and pharmacodynamics of GCSF in a neutropenic rat model. XTEN tag was genetically fused to the N-terminal region of GCSF-encoding gene fragment and subcloned into pET28a expression vector. The cytoplasmic expressed recombinant protein was characterized through intrinsic fluorescence spectroscopy (IFS), dynamic light scattering (DLS), and size exclusion chromatography (SEC)...

BACKGROUND: Multiple studies have demonstrated that human neurobiology and behavior is inextricably linked to the activity of our immune systems. Trauma is associated with a multitude of immune system changes; reflecting this, PTSD is often comorbid with immune related conditions such as autoimmune disorders. To further investigate this phenomenon, we tested our hypothesis that cytokine fluctuations during and after an acute stress response correlates with experienced life trauma. METHODS: Using a prospective observational approach, this cohort study measured biomarker profiles in firefighter participants (n = 63), with 9 participants having prior PTSD diagnoses, and 54 without prior PTSD diagnoses...

Introduction: The long duration of tuberculosis treatment, as well as the 2-year post-treatment follow-up period often required for predicting relapse, present a hindrance to drug development and treatment monitoring efforts. There is an urgent need for biomarkers of treatment response to aid treatment time shortening, clinical decision-making, and inform clinical trials. Objectives: To assess the abilities of selected serum host biomarkers to predict treatment response among active PTB patients. Methods: Active pulmonary TB patients (n = 53) as confirmed by sputum MGIT culture were enrolled at a TB treatment center in Kampala, Uganda...
