Introduction: Commissioning, calibration, and quality control procedures for nuclear medicine imaging systems are typically performed using hollow containers filled with radionuclide solutions. This leads to multiple sources of uncertainty, many of which can be overcome by using traceable, sealed, long-lived surrogate sources containing a radionuclide of comparable energies and emission probabilit
Chest computed tomography (CT) imaging with the use of an artificial intelligence (AI) analysis program has been helpful for the rapid evaluation of large numbers of patients during the COVID-19 pandemic. We have previously demonstrated that adults with COVID-19 infection with high-risk obstructive sleep apnea (OSA) have poorer clinical outcomes than COVID-19 patients with low-risk OSA. In the cur
BACKGROUND: There are few data on outcomes after reintervention for persistent or recurrent primary hyperparathyroidism (PHPT). The authors hypothesized that the variation in outcomes at the hospital level after reoperation would be significant. After accounting for this variability, some patient-level clinical criteria could be identified to help inform treatment decisions in this patient populat
Background and purpose — Concerns exist regarding the generalizability of results from randomized controlled trials (RCTs) evaluating arthroscopic partial meniscectomy (APM) to treat degenerative meniscus tears. It has been suggested that study populations are not representative of subjects selected for surgery in daily clinical practice. There-fore, we aimed to compare patients included in trials
To specify the incidence and risk factors for secondary autoimmune diseases (ADs) after HSCT for a primary AD, we retrospectively analyzed AD patients treated by HSCT reported to EBMT from 1995 to 2009 with at least 1 secondary AD (cases) and those without (controls). After autologous HSCT, 29 of 347 patients developed at least 1 secondary AD within 21.9 (0.6-49) months and after allogeneic HSCT,
This pilot study aimed to investigate whether mammographic compression procedures might cause shedding of tumor cells into the circulatory system as reflected by circulating tumor cell (CTC) count in peripheral venous blood samples. From March to October 2012, 24 subjects with strong suspicion of breast malignancy were included in the study. Peripheral blood samples were acquired before and after
A search is preseritecl for same-sign top-quark production and down-type heavy quarks of charge -1/3 in events with two isolated leptons (c or mu) that have the same electric charge, at least two jets and large missing transverse momentum. The data are selected from pp collisions at root s = 7 TeV recorded by the ATLAS detector and correspond to an integrated luminosity of 1.04 fb(-1). The observe
A methodology for local stakeholders' involvement in water management using a catchment model as a platform for dialogue has been developed and tested in the Kaggebo Bay drainage area in the southeast of Sweden. The process involved farmers, rural households not connected to municipal wastewater treatment facilities, local and regional authorities as well as different water and agricultural expert
OBJECTIVE: The objective of the study was to estimate the risk for postoperative adhesions and intestinal obstruction after cesarean delivery and to estimate whether the rate remains stable over time. STUDY DESIGN: Women who had the aforementioned diagnoses in the Swedish Hospital Discharge Registry were linked to the Swedish Medical Birth Registry. Women with diagnoses increasing the risk for adh
Few studies on fall risk factors use long-recommended methods for analysis of recurrent events. Previous falls are the biggest risk factor for future falls, but few fall studies focus on the youngest-old.
A methodology for evaluation of natural draft cooling tower (CT) performance and its application is presented. The study establishes the connection between CT performance and power output. It can estimate a change in a CT’s efficiency as well as an increase in power output as a function of cooling water temperature and load to the plant. The methodology consists of three subparts, i.e. Cooling Tow
Robot-assisted surgery is a promising technical innovation. Given the similarities between laparoscopic and robot-assisted surgery it is unlikely that randomized controlled trials would be conducted to disclose any differences between these two technical instruments. Thus, skepticism remains due to lack of any definitive conclusions in the literature.
Abstract in UndeterminedPicture books and other visual merchandize for children and youth have a central role in Euro-American Sunni Muslim efforts at religious socialization. The proposed paper aims at making some analytical remarks on the complex cultural interplay inherent to the visual aspects of such pedagogic–cum–commercial material.Islamic children’s literature originated in Muslim American
The nucleotide sequence coding for the beta chain of murine C3 was determined from cloned cDNA and genomic DNA fragments. Sonicated subfragments were randomly inserted into the bacteriophage M13 and sequenced using the dideoxynucleotide technique. Each nucleotide was sequenced on average six times in these studies. The derived amino acid sequence includes a signal peptide and a tetra-arginine sequ
Daylight is crucial for the well-being of individuals in indoor environments, providing numerous physiological and psychological benefits. Achieving satisfactory daylight levels can be particularly challenging during adaptive reuse of existing buildings for new purposes. This study determined the feasibility of adapting an office for residential use by assessing interior daylight availability and
The ALICE Collaboration reports measurements of the large relative transverse momentum (kT) component of jet substructure in pp and Pb-Pb collisions at center-of-mass energy per nucleon pair sNN=5.02 TeV. Enhancement in the yield of such large-kT emissions in head-on Pb-Pb collisions is predicted to arise from partonic scattering with quasiparticles of the quark-gluon plasma. The analysis utilizes
