Introduction: Long-term care (LTC) residents, especially the orally fed with dysphagia, are prone to dehydration. The clinical consequences of dehydration are critical. The validity of the common laboratory parameters of hydration status is far from being absolute, especially so in the elderly. However, combinations of these indices are more reliable. Objective: Assessment of hydration status among elderly LTC residents with oropharyngeal dysphagia. Methods: A total of 28 orally fed patients with grade-2 feeding difficulties on the functional outcome swallowing scale (FOSS) and 67 naso-gastric tube (NGT)-fed LTC residents entered the study. The common laboratory, serum and urinary tests were used as indices of hydration status. The results were considered as indicative of dehydration and used as ‘markers of dehydration’, if they were above the accepted normal values. Results: The mean number of dehydration markers was significantly higher in the FOSS-2 group (3.8 ± 1.3 vs. 2 ± 1.4, p = 0.000). About 75% of these FOSS-2 patients had ≧4 dehydration markers versus 18% of the NGT-fed group (p = 0.000). A low urine output (<800 ml/day) was significantly more common in the FOSS-2 group (39 vs. 12%, p = 0.002). Above normal values of blood urea nitrogen (BUN), BUN/serum creatinine ratio (BUN/SCr), urine/serum osmolality ratio (U/SOsm), and urine osmolality UOsm, were significantly more frequent in the dehydration-prone FOSS-2 group. This combination of 4 indices was present in 65% of low urine output patients. In contrast, it was present in only 36% of the higher urine output patients (p = 0.01). Patients with a ‘normal’ daily urine output (>800 ml/day) also had a significant number (2 ± 1.5) of positive indices of dehydration. Conclusions: Dehydration was found to be common among orally fed FOSS-2 LTC patients. Surprisingly, probable dehydration, although of a mild degree, was not a rarity among NGT-fed patients either. The combination of 4 parameters, BUN, BUN/SCr , U/SOsm and UOsm, offers reasonable reliability to be used as an indication of dehydration status in daily clinical practice.
The incidences of anemia and decreased serum B12 levels were high in these three groups of rheumatic patients. However, true tissue deficiency seems to be much rarer.
Apparently, with aging the immune surveillance of the already immune privileged prostate is progressively and further affected. This condition may result in the inability of the gland to eradicate emergent malignant cells.
Blood transfusion is a widely used supportive treatment of cancer patients, most of whom are anemic. In the particular subset of cancer patients that undergoes chemotherapy, blood transfusion is viewed as an essential part of supportive care. However, the place of blood transfusion in anemic terminally ill cancer patients is far less established. There are no well-defined blood transfusion guidelines ("transfusion trigger") for these patients. Hence, transfusion decisions are greatly influenced by the personal views of the medical team. Therefore, a mail survey of 500 physicians (from several specialties) and nurses was initiated to assess their personal opinions on this topic. The overall response rate was relatively high (70%). There was broad agreement that blood transfusions, as a rule, should not be withheld from terminal cancer patients. On the other hand, only nurses were of the opinion that these patients should be transfused "as usual." Significantly, there was but a slight majority (53% of participants) that was of the opinion that transfusions to these patients do not prolong suffering. There emerged a short list of agreed-on suggestions for blood transfusion--namely, Hb level < or = 7 mg/dL, active bleeding (acute and/or occult), functional deterioration of the patient, presence of anemia resulting from chemotherapy, anginal symptoms, dyspnea, and worsening congestive heart failure. The agreed-on suggestions for transfusions in terminally ill cancer patients may serve as a reasonable physician standard for this complex clinical, medical-legal, and emotional issue.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
