Estimating the CTDI with helical acquisitions: Results from a national generalizability study.

Background: While many clinical computed tomography (CT) protocols use helical scanning, the traditional method for measuring the volume CT Dose Index (CTDI) requires modifying the helical protocol to perform a single axial rotation. This modification can present challenges and mismatched settings across various scanner models.

Purpose: This study investigates the generalizability of a helical methodology for estimating CTDI across a diverse range of participants, CT scanner models, and protocol parameters.

Multifaceted growth promotion and biocontrol of Agroathelia rolfsii and induction of defense mechanism by Bacillus amyloliquefaciens SS-CR10 on chilli.

Plant-growth-promoting (PGP) endophytic bacteria are beneficial microorganisms that can help plants withstand biotic stress caused by fungal phytopathogens. In the present study, 78 endophytic bacterial isolates were isolated from chilli (Capsicum annuum L.).

Ranking the Relative Importance of Image Quality Features in CT by Consensus Survey.

Objective: This study sought to determine consensus opinions from subspecialty radiologists and imaging physicists on the relative importance of image quality features in CT.

Methods: A prospective survey of subspecialty radiologists and medical physicists was conducted to collect consensus opinions on the relative importance of ten image quality features: axial sharpness, blooming, contrast, longitudinal sharpness, low contrast axial sharpness, metal artifact, motion, noise magnitude, noise texture, and streaking. The survey was first sent to subspecialty radiologists in volunteer leadership roles in the American College of Radiology and Radiological Society of North America, thereafter relying on snowball sampling.

Acetabular fracture in India: An epidemiological study.

Introduction: Acetabular fractures, resulting from high-energy trauma, present significant orthopaedic challenges. Despite their rarity, the incidence of these fractures is rising, necessitating a comprehensive understanding of their epidemiological characteristics, especially in diverse populations like India.

Methods: This retrospective study analyzed data from 3643 patients across four level-1 trauma centers in India (North 1, North 2, West, and South) from January 2001 to December 2019.

Radiological and Hematological Parameters Predicting Success of Medical Expulsive Therapy in Patients With Ureteral Calculus.

Background Urolithiasis, characterized by the formation of stones in the urinary tract, is a common condition with significant morbidity. Medical expulsive therapy (MET) has emerged as a non-invasive treatment modality for facilitating the spontaneous passage of ureteral stones. However, MET success varies widely among individuals, and identifying predictive factors for treatment outcomes is crucial for optimizing patient care.

Comparison of Sagittal Condylar Guidance Angle Obtained by Radiographic Methods and Manual Programming of Articulators in Dentate Patients - A Clinico-radiographic Study.

Background: The ultimate goal of advanced procedures in prosthetic dentistry is to construct a prosthesis based on the accurate reproduction of condylar guidance.

Aim: To compare the sagittal condylar inclination obtained using the cone-beam computed tomography (CBCT), panoramic image, and two articulator systems.

Settings And Design: A cross-sectional study was carried out in 20 dentate patients in the age group of 20-40 years.

Diversity and representation within the literature on sexual dysfunction in multiple sclerosis: A systematic review.

Introduction: Sexual dysfunction (SD) is a common and distressing symptom for people living with multiple sclerosis (MS). Populations included in existing studies of SD may not fully reflect the diversity of people living with MS, with important implications for wider applicability. We aimed to evaluate reporting of sex, gender identity, sexual orientation, and ethnicity across studies of SD in MS.

Recurrent medical imaging exposures for the care of patients: one way forward.

Medical imaging is both valuable and essential in the care of patients. Much of this imaging depends on ionizing radiation with attendant responsibilities for judicious use when performing an examination. This responsibility applies in settings of both individual as well as multiple (recurrent) imaging with associated repeated radiation exposures.

Analytical method development, identification, and characterization of stress degradation products of idelalisib by ultrahigh-performance liquid chromatography with photodiode array and ultrahigh-performance liquid chromatography with electrospray ionization quadrupole time-of-flight mass spectrometry studies.

Rationale: As per International Council for Harmonization (ICH) drug stability test guideline Q1A(R2), inherent stability characteristics of a drug should be studied. This work was designed to investigate inherent degradation characteristics of the drug idelalisib under ICH prescribed stress conditions, identify its degradation products, and postulate their corresponding degradation pathways.

Methods: Idelalisib was subjected to the ICH prescribed conditions of hydrolytic (neutral, acidic, and alkaline), photolytic, oxidative, and thermal stress according to ICH guideline Q1A(R2).

Low Dose Radiation and Solid Tumors Mortality Risk.

Background: US nuclear capable shipyard workers have increased potential for occupational radiation exposure.

Objective: The aim of the study is to examine solid tumor mortality risks at low doses.

Method: 437,937 workers working from 1957 to 2004 at eight US shipyards were studied.

Proposed Priorities for Low-Dose Radiation Research and Their Relevance to the Practice of Radiology.

Because ionizing radiation is widely used in medical imaging and in military, industry, and commercial applications, programmatic management and advancement in knowledge is needed, especially related to the health effects of low-dose radiation. The U.S.

Ethnic differences in early onset multimorbidity and associations with health service use, long-term prescribing, years of life lost, and mortality: A cross-sectional study using clustering in the UK Clinical Practice Research Datalink.

Background: The population prevalence of multimorbidity (the existence of at least 2 or more long-term conditions [LTCs] in an individual) is increasing among young adults, particularly in minority ethnic groups and individuals living in socioeconomically deprived areas. In this study, we applied a data-driven approach to identify clusters of individuals who had an early onset multimorbidity in an ethnically and socioeconomically diverse population. We identified associations between clusters and a range of health outcomes.
