Methods: Retrospective review of all patients included in the large Spanish multicentre registry for GCA (ARTESER) with at least two years of follow-up. SDFR was defined as the absence of typical signs, symptoms, or other features of active GCA for ≥12 months after discontinuation of treatment.

Mixed epithelial and stromal tumor of the kidney: A case report in elderly male patient.

Mixed epithelial and stromal tumor (MEST) is very rare neoplasm of the kidney, commonly affecting women at menopausal age. MEST is usually considered a benign tumor with low risk of local recurrence or distance metastases. Our case presents a case of a 66 years old male patient with a complex cystic lesion of the left kidney incidentally diagnosed on urinary tract computerized scan (CT) performed for other reasons.

The prognostic effect of neutrophil-to-lymphocyte ratio and De Ritis ratio in glioblastoma multiforme patients.

Aims: Individuals with a higher De Ritis ratio (aspartate transaminase/alanine transaminase) and neutrophil-to-lymphocyte ratio (NLR) have an inferior survival in varied malignancies. To our knowledge, the prognostic potential of the De Ritis ratio and NLR to predict the survival in nonmetastatic glioblastoma multiforme (GBM) patients remains unclear. In this study, we aimed to explore the prognostic power of the De Ritis ratio and NLR in patients with nonmetastatic glioblastoma multiforme.

The Concentration of Uranium-238 in Soil Samples from the Central Maysan Governorate Determined Using ICP-MS.

In this particular investigation, 30 surface soil samples taken from various locations across the Middle Omara governorate in southeastern Iraq were analyzed using ICP-MS (inductively coupled plasma mass spectrometry), and several of these, as far as the researchers know, had never been analyzed previously. The results are presented and compared with those from a different study. The studied soil samples had <100 ppm of uranium, which shows they are composed of overloads and garbage rather than mineable stocks.

Regorafenib therapy as a third-line treatment for metastatic colorectal cancer: A single center long term experience.

This study examined the effects of regorafenib (Reg) on progression-free survival (PFS), overall survival (OS), and adverse events (AEs) in metastatic colorectal cancer (mCRC) patients who underwent targeted treatment and chemotherapy. Reg was administered as a third-line treatment to 84 patients who had undergone 2 rounds of chemotherapy and targeted therapy and subsequently experienced progression. Treatment was initiated with a daily dose of 80 or 120 mg, based on the patient's ability to tolerate the medication, which was increased to 160 mg/day.

Materials And Methods: mNSCLC patients were retrospectively evaluated from January 2016 to December 2019.

The relationship between sarcopenia detected in newly diagnosed colorectal cancer patients and FGF21, irisin and CRP levels.

Aim: Sarcopenia is a progressive and generalized syndrome that can be linked to many causes such as cancers, and is caused by a quantitative and qualitative disorder (loss of muscle strength and/or physical performance) of skeletal muscle mass. Although sarcopenia has some hypothetical explanation in clinical practice, the mechanisms underlying this condition have not been clearly differentiated in patients with cancer. We aimed to investigate the relationship between irisin, FGF21 and CRP in detecting sarcopenia in colorectal cancer patients.

Being a Cancer Patient during the Time of COVID-19: Impact of the Pandemic on the Anxiety and the Sleeping Quality of Oncology Patients.

Objective: In this study, we aimed to assess anxiety and sleep quality in cancer patients treated or followed up at our clinic at the time of the outbreak of the COVID-19 pandemic.

Co-treatment with low doses of buspirone prevents rewarding effects of methylphenidate and upregulates expression of 5-HT1A receptor mRNA in the nucleus accumbens.

Accumulating studies consistently show that methylphenidate (MPD), the first line drug for treating Attention-Deficit Hyperactivity Disorder (ADHD), is abused by patients to whom the drug is prescribed. Like other psychostimulants, only low doses of MPD improve cognitive performance while higher doses impair it. Preventing the use of high doses of MPD is important for retaining its therapeutic efficacy.

Hyaluronic acid as a potential marker for assessment of fibrosis regression after direct acting antiviral drugs in chronic hepatitis C patients.

Introduction: Fibrosis is an inevitable complication of chronic hepatitis C virus (HCV) infection. Direct acting antivirals (DAAs) radically treated HCV and were suggested to ameliorate fibrosis. Silymarin (a natural herbal remedy) was proposed to further decrease hepatic inflammation and fibrosis.

Evaluation of different diagnostic modalities of minimal hepatic encephalopathy in cirrhotic patients: case-control study.

Introduction: Minimal hepatic encephalopathy (MHE) represents one of the most overlooked complications of liver cirrhosis.

Material And Methods: This case-control study was conducted on hepatitis C virus (HCV)-related compensated cirrhotic patients.

Differential effects of memory enhancing and impairing doses of methylphenidate on serotonin metabolism and 5-HT1A, GABA, glutamate receptor expression in the rat prefrontal cortex.

Methylphenidate (MPD), a psychostimulant, is a prescription medicine for treating attention deficit hyperactivity disorder (ADHD). Previously we have shown that moderate doses of MPD enhanced learning and memory while higher doses impaired it. To understand neurochemical mechanisms and receptors involved in memory enhancing and impairing effects of MPD, the present study concerns the effects of these doses of MPD on serotonin, 5-HT1A, GABA, and NMDA receptor mRNA expression in the prefrontal cortex (PFC).
