Bone density, Internal medicine, Bone mineral, Osteoporosis and Breast cancer are his primary areas of study.
His study in Bone density is interdisciplinary in nature, drawing from both Medical physics, Lumbar vertebrae and Dual-energy X-ray absorptiometry.
His Internal medicine course of study focuses on Endocrinology and Percentile.
The various areas that John A. Shepherd examines in his Bone mineral study include Young adult and Surgery.
His Osteoporosis research is multidisciplinary, relying on both Femur, Physical therapy, Activities of daily living, Natural history and Physical examination.
His research in Breast cancer intersects with topics in Gynecology and Oncology.
His most cited work include:
- Comparisons of percentage body fat, body mass index, waist circumference, and waist-stature ratio in adults (526 citations)
- The Bone Mineral Density in Childhood Study: Bone Mineral Content and Density According to Age, Sex, and Race (295 citations)
- Revised Reference Curves for Bone Mineral Content and Areal Bone Mineral Density According to Age and Sex for Black and Non-Black Children: Results of the Bone Mineral Density in Childhood Study (290 citations)
What are the main themes of his work throughout his whole career to date?
His main research concerns Internal medicine, Breast cancer, Bone mineral, Nuclear medicine and Mammography.
John A. Shepherd studied Internal medicine and Endocrinology that intersect with Cohort.
His Breast cancer study incorporates themes from Body mass index, Gynecology and Risk factor.
His study looks at the relationship between Bone mineral and fields such as Bone density, as well as how they intersect with chemical problems.
John A. Shepherd interconnects Repeatability, Densitometry and Dual-energy X-ray absorptiometry in the investigation of issues within Nuclear medicine.
His Mammography research integrates issues from Odds ratio and Radiology.
He most often published in these fields:
- Internal medicine (28.03%)
- Breast cancer (25.42%)
- Bone mineral (19.95%)
What were the highlights of his more recent work (between 2017-2021)?
- Internal medicine (28.03%)
- Breast cancer (25.42%)
- Endocrinology (12.35%)
In recent papers he was focusing on the following fields of study:
John A. Shepherd spends much of his time researching Internal medicine, Breast cancer, Endocrinology, Bone mineral and Anthropometry.
His biological study spans a wide range of topics, including Type 2 diabetes and Oncology.
The Breast cancer study combines topics in areas such as Body mass index and Confidence interval.
His Choline study in the realm of Endocrinology interacts with subjects such as Context.
His Bone mineral study integrates concerns from other disciplines, such as Bone density, Randomized controlled trial, Dentistry and Femoral neck.
His Anthropometry research includes elements of Optical imaging and Accuracy and precision.
Between 2017 and 2021, his most popular works were:
- Early safety indicators of COVID-19 convalescent plasma in 5000 patients. (208 citations)
- Convalescent Plasma Antibody Levels and the Risk of Death from Covid-19. (69 citations)
- Executive Summary of the 2019 ISCD Position Development Conference on Monitoring Treatment, DXA Cross-calibration and Least Significant Change, Spinal Cord Injury, Peri-prosthetic and Orthopedic Bone Health, Transgender Medicine, and Pediatrics (53 citations)
In his most recent research, the most cited papers focused on:
- Internal medicine
- Cancer
- Radiology
His primary scientific interests are in Internal medicine, Bone mineral, Endocrinology, Obesity and Anthropometry.
Internal medicine is closely attributed to Type 2 diabetes in his work.
His Bone mineral research includes themes of Pregnancy, Clinical trial, Randomized controlled trial, Pediatrics and Femoral neck.
His study on Vitamin D and neurology is often connected to Context as part of broader study in Endocrinology.
His study on Anthropometry also encompasses disciplines like
- Accuracy and precision, which have a strong connection to Functional training, Isometric exercise, Visceral fat and Nuclear medicine,
- Circumference together with Waist and Mexican americans.
John A. Shepherd focuses mostly in the field of Nuclear medicine, narrowing it down to topics relating to Plethysmograph and, in certain cases, Dual-energy X-ray absorptiometry.
