Mortality after nasogastric tube feeding initiation in long-term care elderly with oropharyngeal dysphagia--the contribution of refeeding syndrome

Emilia LubartRefael Segal


The refeeding syndrome (RS) is an underappreciated but clinically important entity characterized by acute electrolyte abnormalities, mainly hypophosphatemia, fluid retention and dysfunction of various organs and systems, which can result in significant morbidity and occasionally death. To examine the incidence of death cases and death causes following nasogastric tube (NGT) feeding initiation in frail elderly with particular reference to RS. Forty patients with feeding problems for at least 72 h before restarting of alimentation by NGT were included. Excluded were those in any critical clinical situation. Clinical parameters and nutritional assessment were recorded before and after refeeding. Blood samples were taken before, daily for the first 3 days and 1 week after refeeding initiation. During the 1st week of refeeding, 9 patients (22.5%) died and within 1 month 10 more, summing to 47.5%. Most deaths were due to infectious causes [15 out of 19, (79%)]; some were due to no obvious reason [4 out of 19, (21%)]. Significant electrolyte changes were observed in the 2-3 days following refeeding. Significant were the decreases in phosphorus and elevations in potassium and lymphocytes (day 7). We found no correlations between the se...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
