Zinc Tập 30 Số 3 - Trang 371-382 - 2015
Callum Livingstone
The essential trace element zinc (Zn) has a large number of physiologic roles,
in particular being required for growth and functioning of the immune system.
Adaptive mechanisms enable the body to maintain normal total body Zn status over
a wide range of intakes, but deficiency can occur because of reduced absorption
or increased gastrointestinal losses. Deficiency impairs physiologic processes,

The Validity of Bioelectrical Impedance Models in Clinical Populations Tập 19 Số 5 - Trang 433-446 - 2004
Andrea C. Buchholz, Cynthia Bartok, Dale A. Schoeller
Bioelectrical impedance analysis (BIA) is the most commonly used body
composition technique in published studies. Herein we review the theory and
assumptions underlying the various BIA and bioelectrical impedance spectroscopy
(BIS) models, because these assumptions may be invalidated in clinical
populations. Single‐frequency serial BIA and discrete multifrequency BIA may be
of limited validity in ... hiện toàn bộ
Unraveling Mechanisms of Action of Probiotics Tập 24 Số 1 - Trang 10-14 - 2009
Philip M. Sherman, Juan C. Ossa, Kathene C. Johnson‐Henry
Probiotics are defined as living organisms that, when administered in sufficient
numbers, are of benefit to the host. Current evidence indicates that varying
probiotic strains mediate their effects by a variety of different effects that
are dependent on the dosage employed as well as the route and frequency of
delivery. Some probiotics act in the lumen of the gut by elaborating
antibacterial molec... hiện toàn bộ
Zinc and Liver Disease Tập 27 Số 1 - Trang 8-20 - 2012
Mohammad K. Mohammad, Mohammad K Mohommad, Zhanxiang Zhou, Matthew C. Cave, Ashutosh Barve, Craig J. McClain
Zinc is an essential trace element required for normal cell growth, development,
and differentiation. It is involved in DNA synthesis, RNA transcription, and
cell division and activation. It is a critical component in many zinc
protein/enzymes, including critical zinc transcription factors. Zinc
deficiency/altered metabolism is observed in many types of liver disease,
including alcoholic liver dis... hiện toàn bộ
D‐Lactic Acidosis Tập 20 Số 6 - Trang 634-645 - 2005
Craig Petersen
d‐Lactic acidosis, also referred to as d‐lactate encephalopathy, is a rare
neurologic syndrome that occurs in individuals with short bowel syndrome or
following jejuno‐ileal bypass surgery. Symptoms typically present after the
ingestion of high‐carbohydrate feedings. Neurologic symptoms include altered
mental status, slurred speech, and ataxia, with patients often appearing drunk.
Onset of neurolo... hiện toàn bộ
Barriers to Providing Nutrition Counseling Cited by Physicians Tập 25 Số 5 - Trang 502-509 - 2010
Kathryn M. Kolasa, Katherine Rickett
In a 1995 pivotal study, Kushner described the attitudes, practice behaviors,
and barriers to the delivery of nutrition counseling by primary care physicians.
This article recognized nutrition and dietary counseling as key components in
the delivery of preventive services by primary care physicians. Kushner called
for a multifaceted approach to change physicians’ counseling practices. The

Implications of Sarcopenia in Major Surgery Tập 30 Số 2 - Trang 175-179 - 2015
Jeffrey F. Friedman, Alisha Lussiez, J. A. Sullivan, Stewart C. Wang, Michael J. Englesbe
Background: Sarcopenia, defined as a decrease in skeletal muscle mass and
strength, is an important risk factor in clinical medicine associated with
frailty, mortality, and worse surgical and nonsurgical outcomes. Conventional
measures of sarcopenia rely on the subjective “eyeball test” and do not
adequately describe risk. Computed tomography (CT) imaging studies may be used
to objectively measure... hiện toàn bộ
Copper Deficiency: Causes, Manifestations, and Treatment Tập 34 Số 4 - Trang 504-513 - 2019
Marco Altarelli, Nawfel Ben‐Hamouda, Antoine Schneider, Mette M. Berger
AbstractBackgroundThe metabolism of the essential trace element copper remains
incompletely understood and, until recently, nearly ignored in acute medicine.
Menkes disease was for long the only known copper deficiency condition, but
several case reports and investigations conducted over the last 2 decades have
shown that deficiency is more frequent than previously suspected, with
devastating indi... hiện toàn bộ
Vitamin D and Rehabilitation: Improving Functional Outcomes Tập 22 Số 3 - Trang 297-304 - 2007
Leonid M. Shinchuk, Michael F. Holick
Vitamin D inadequacy is pandemic among rehabilitation patients in both inpatient
and outpatient settings. Male and female patients of all ages and ethnic
backgrounds are affected. Vitamin D deficiency causes osteopenia, precipitates
and exacerbates osteoporosis, causes the painful bone disease osteomalacia, and
worsens proximal muscle strength and postural sway. Vitamin D inadequacy can be
