PSMA-ligand PET for early castration-resistant prostate cancer: a retrospective single-center study
Low detection rate of conventional imaging and unspecific fluctuations of PSA can hamper early diagnosis of castration-resistant prostate cancer (CRPC). We thus assessed the value of PSMA-PET/CT in the detection of early CRPC (PSA ≤3 ng/mL). Methods: We identified 55 patients with early CRPC (PSA≤3 ng/mL) from our institutional database. PSMA-PET/CT and its CT component were interpreted independently by three blinded readers. Primary endpoint was the per-patient detection rate, secondary endpoints...

Risk of bowel obstruction in patients with mesenteric/peritoneal disease receiving peptide receptor radionuclide therapy (PRRT)
Background: Although radiation-induced mesenteritis or peritonitis can potentially exacerbate the risk of bowel obstruction, there are no data in the literature on the incidence of intestinal obstruction related to peptide receptor radionuclide therapy (PRRT). Methods: Records of all patients treated with 177Lu-Dotatate at Moffitt Cancer Center between 4/2018 and 10/2019 were evaluated. The number of patients who developed bowel obstruction within 3 months of a 177Lu-Dotatate treatment was...

Imaging the cancer immune environment and its response to pharmacological intervention- Part 1- The role of FDG PET/CT
Immunotherapy agents are now entering the clinic in a wide array of malignancies and have provided a valuable addition to the therapeutic armamentarium. These agents enhance the global immune response by modulating the tumor microenvironment but can lead to unconventional patterns of response, challenging the conceptual framework that imaging is a robust surrogate for therapeutic efficacy. There is also increasing evidence that an effective anti-tumor response requires a systemic immune response...

Synthesis of novel PET tracer 124I-trametinib for MAPK/ERK kinase distribution and resistance monitoring
Trametinib (MEKINIST™) is an extremely potent allosteric inhibitor of MEK1/2 that has been approved for treatment of metastatic melanoma and anaplastic thyroid cancer in patients with confirmed BRAFV600E/K mutations. Though highly efficacious, adverse side effects including skin, gastrointestinal and hepatic toxicity, are dose limiting and can lead to treatment termination. Development of a non-invasive tool to visualize and quantify the delivery and distribution of trametinib (either as single agent...

The prognostic value of quantitative bone scan SPECT/CT prior to 223Ra treatment in metastatic castration-resistant prostate cancer (mCRPC)
Rationale: Radiolabelled bisphosphonates such as 99mTc-DPD typically show intense uptake in skeletal metastases from metastatic castration resistant prostate cancer (mCRPC). Extensive bone involvement is regarded a risk factor for mCRPC patients treated with 223Ra-radiumdichloride (223Ra). Aim of this study was to quantify 99mTc-DPD uptake by means of SPECT/CT prior to 223Ra and compare results to the feasibility of treatment and overall survival (OS). Methods: 60 consecutive mCRPC patients were...

Sleep Quality and Associated Factors among Diabetes, Hypertension, and Heart Failure Patients at Debre Markos Referral Hospital, Northwest Ethiopia
Background. Chronic illnesses have a negative impact on the quality of sleep; however, patients with chronic illness do not bring sleep issues while they are coming to a health institution for a follow-up. As a result, poor sleep quality among patients with chronic illness is often unrecognized and untreated, and it results to a negative impact on the prognosis of chronic illness. Methods. An institutional-based cross-sectional study design was employed from February 22, 2018, to April 6, 2018. The...

“Not Above, Not Below: Right in the Middle!”—Novel Filler Technique for Temporal Augmentation and Rejuvenation
Facial Plast SurgDOI: 10.1055/s-0040-1709710The temporal region is challenging to treat due to its thin skin, which has the propensity toward showing irregularities. The literature on temporal hollowing augmentation suggests placing the filler either into the subcutaneous space or within the temporalis muscle. However, these techniques have been based upon opinion rather than supporting anatomical and clinical data. We introduce a novel injection technique to avoid complications and achieve lasting...

Persistence of Antipsychotic Use After Clozapine Discontinuation: A Real‐World Study Across Antipsychotics
Although clozapine treatment is often discontinued due to limited efficacy or low tolerability, there is a lack of guidelines and evidence on treatment options after discontinuation of clozapine in patients with schizophrenia. Persistence has proven to be an adequate indicator for treatment effectiveness in patients with schizophrenia. The aim of this study was, therefore, to compare persistence of antipsychotic use between antipsychotic treatment options in patients after stopping clozapine treatment....

MiRNA-495-3p Attenuates TNF-α Induced Apoptosis and Inflammation in Human Nucleus Pulposus Cells by Targeting IL5RA
Abstract Intervertebral disc degeneration (IVDD) is considered to be the fundamental cause of the occurrence and development of lumbar disc herniation (LDH). The degeneration of IVDD is mainly caused by the participation of inflammatory factors. Thus, it is of great significance to analyze the pathogenesis of IVDD, which may guide clinical prevention and treatment of LDH. Our current study aims to identify the role of miR-495-3p in LDH and to further unravel the underlying mechanisms....

Abstract Alzheimer’s disease (AD) is a serious neuropathologic disease characterized by aggregation of amyloid-β (Aβ) peptide. Aβ-mediated oxidative stress and neuroinflammation play crucial role in the development of AD. Engeletin is a flavononol glycoside that possesses anti-inflammatory effect. However, the effects of engeletin on AD have not been investigated. In the present study, we investigated the role of engeletin in AD using...

Adult mesentero‐axial gastric volvulus: Case report
Summary Acute gastric volvulus is a rare surgical emergency which can lead to severe complications such as gastric ischaemia and perforation. Gastric volvulus is classified by the axis upon which the stomach rotates into organo‐axial and mesentero‐axial subtypes, with the former more common in adults. We present an uncommon case of recurrent adult mesentero‐axial gastric volvulus and describe the associated radiological findings.

Abstract In an earlier article, Gordon Drummond summarized ongoing changes in how statistics are being used in experimental physiology (Drummond, 2020). He described the near ubiquitous use of the P value, cautioning against declaring an analysis “statistically significant”. He mentioned alternative approaches including Bayesian and likelihood approaches. This article focusses on the latter approach although we will first have another look at that P value. Then the likelihood approach will be...
