Malnutrition and dehydration are potential consequences of dysphagia, a common swallowing disorder among elderly individuals. Providing smaller, more frequent meals has been suggested (but not demonstrated) to improve energy intake among this group. Accordingly, this study was designed to assess whether the same energy content in five vs three daily meals would improve energy intake. Thirty-seven residents of an extended-care facility, aged older than 65 years, previously evaluated for dysphagia, and receiving a texture-modified diet, agreed to participate in a crossover study with random assignment to three or five meals during an initial 4-day study period, followed by the opposite meal pattern in a second period. Six were excluded from analysis, as their medical condition deteriorated before or during the study. Food and fluids consumed by participants during each study period were weighed before and after each meal. Average energy intakes were similar between the three- and five-meal patterns (1,325+/-207 kcal/day vs 1,342+/-177 kcal/day, respectively; P=0.565); fluid intake was higher with five meals (698+/-156 mL/day) vs three (612+/-176 mL/day; P=0.003). Because offering five daily feedings did not improve energy intakes when compared with three, dietitians caring for this vulnerable group might need to consider other nutrition intervention strategies.

When patients have severe dysphagia after a stroke, tube feeding may be recommended to reduce the risks associated with malnutrition, dehydration, and/or aspiration. Patients may not be able to participate in decision making, but they may have previously expressed strong preferences related to tube feeding. Clinicians must work together with the family to establish a treatment plan that is respectful of the person's previous wishes, yet mindful of the flaws in advance care planning. Although ethical issues cannot be avoided, clinicians can reduce uncertainty by understanding current ethical and legal views on these challenging issues.

Dysphagia, which can lead to nutritional deficiencies, weight loss and dehydration, represents a risk factor for aspiration pneumonia. Although clinical studies have reported the occurrence of dysphagia in patients with spinocerebellar ataxia type 2 (SCA2), type 3 (SCA3), type 6 (SCA6) and type 7 (SCA7), there are neither detailed clinical records concerning the kind of ingestive malfunctions which contribute to dysphagia nor systematic pathoanatomical studies of brainstem regions involved in the ingestive process. In the present study we performed a systematic post mortem study on thick serial tissue sections through the ingestion-related brainstem nuclei of 12 dysphagic patients who suffered from clinically diagnosed and genetically confirmed spinocerebellar ataxias assigned to the CAG-repeat or polyglutamine diseases (two SCA2, seven SCA3, one SCA6 and two SCA7 patients) and evaluated their medical records. Upon pathoanatomical examination in all of the SCA2, SCA3, SCA6 and SCA7 patients, a widespread neurodegeneration of the brainstem nuclei involved in the ingestive process was found. The clinical records revealed that all of the SCA patients were diagnosed with progressive dysphagia and showed dysfunctions detrimental to the preparatory phase of the ingestive process, as well as the lingual, pharyngeal and oesophageal phases of swallowing. The vast majority of the SCA patients suffered from aspiration pneumonia, which was the most frequent cause of death in our sample. The findings of the present study suggest (i) that dysphagia in SCA2, SCA3, SCA6 and SCA7 patients may be associated with widespread neurodegeneration of ingestion-related brainstem nuclei; (ii) that dysphagic SCA2, SCA3, SCA6 and SCA7 patients may suffer from dysfunctions detrimental to all phases of the ingestive process; and (iii) that rehabilitative swallow therapy which takes specific functional consequences of the underlying brainstem lesions into account might be helpful in preventing aspiration pneumonia, weight loss and dehydration in SCA2, SCA3, SCA6 and SCA7 patients.

Artificial nutrition is necessary when oral feeding becomes insufficient to cover protein and energetic needs and becomes dangerous (risk of malnutrition, dehydration and aspiration). In ALS patients, enteral nutrition is the method of choice and gastrostomy is preferable to nasogastric tube which must be limited for a short term enteral nutrition or if gastrostomy is at risk (because of pulmonary function) or refused by the patient. The percutaneous gastrostomy can be placed endoscopically (PEG) or radiologically (RIG), surgical gastrostomy has to be avoided because of general anaesthesia. Advantages of RIG are a success rate of about 100 percent and a placement feasible without sedation but its superiority on PEG in ALS patients especially if pulmonary functions are altered is not demonstrated. No objective criterion permits to define the exact moment of enteral nutrition. However, enteral nutrition is recommended when dysphagia becomes symptomatic (insufficient caloric intake with weight loss, dehydration, frequent choking and aspiration). Swallowing disorders must be detected early to give to patients and their family information about enteral nutrition and gastrostomy as soon as possible and to help them to decide. It is desirable to propose gastrostomy when forced vital capacity is yet above 50 percent and nutritional state not altered (body mass index>18kg/m2 and/or weight loss<10 percent). Enteral nutrition is not desirable in ALS patients with dementia or in the preterminal phase. Suitable enteral nutrition with regular nutritional evaluation can improve nutritional status. Currently, improvement of quality of life and survival due to enteral nutrition has not been proved in ALS patients.

Patients with head and neck cancer are at high risk for malnutrition due to dysphagia from the tumor and treatment. Despite difficulty with oral intake, these patients usually have a normal stomach and lower gastrointestinal tract. Enteral nutrition support via percutaneous endoscopic gastrostomy (PEG) administered in the home by the patient helps to prevent weight loss, dehydration, nutrient deficiencies, treatment interruptions, and hospitalizations. It also improves quality of life. Successful management of these patients requires orderly care and follow-up by a multidisciplinary nutrition team.

Individuals with dysphagia are commonly provided with oral fluids thickened to prevent aspiration. Most thickening agents are either gum-based (guar or xanthan) or are derived from modified starches. There is evidence, predominantly anecdotal, that dysphagic individuals are subclinically dehydrated. Dysphagia has a particular impact on elderly individuals and there is justifiable concern for dehydration in this population. It has been speculated that dehydration may, in part, be the result of the water-holding capacity of these thickening agents decreasing water absorption from the gut. The aim of this study was to determine the rate of intestinal absorption of water from thickened fluids. The method used was a laboratory tracer study in rats and humans in vivo. We found that there were no significant differences in water absorption rates between thickened fluids or pure water irrespective of thickener type (modified maize starch, guar gum, or xanthan gum). These data provide no support for the view that the addition of thickening agents, irrespective of type, to orally ingested fluids significantly alters the absorption rate of water from the gut.

Swallowing problems (dysphagia) can occur at any age but are most prevalent in elderly individuals and are a growing healthcare concern as the geriatric population expands. Without effective diagnosis and treatment, dysphagia may lead to serious medical conditions such as pneumonia, dehydration, and malnutrition. Experts in the field of dysphagia met on August 21, 2001, in Rockville, Maryland, to respond to this heightened healthcare need and to determine the course of dysphagia research. Presentations at the meeting included epidemiological data, geriatric-specific issues, diagnostic techniques, risk factors for pneumonia, and recent relevant trials. The experts identified outstanding issues in dysphagia research, such as study design, population selection, and the standardization of diagnostic and treatment protocols. They designed a clinical trial that represents what they deem is one of the greatest needs in dysphagia research, providing a critical springboard for research endeavors with far-reaching implications.

Many people with Down's syndrome (DS) experience eating, drinking, and swallowing (EDS) difficulties, which can potentially lead to life-threatening conditions such as malnutrition, dehydration, and aspiration pneumonia. As the life expectancy of people with DS continues to improve, there is an increasing need to examine how the aging process may further affect these conditions. Published research studies have yet to address this issue; therefore, this article draws on the literature in three associated areas in order to consider the dysphagic problems that might develop in aging people with DS. The areas examined are EDS development in children and adolescents with DS, EDS changes associated with aging, and EDS changes associated with dementia of the Alzheimer's type (DAT) because this condition is prevalent in older adults with DS. This article concludes that unlike in the general population, the aging process is likely to cause dysphagic difficulties in people with DS as they get older. Therefore, it is suggested that longitudinal studies are needed to examine the specific aspects of EDS function that may be affected by aging and concomitant conditions in DS.

Mucositis is a common complication of cancer therapy and can be a debilitating and dose-limiting toxicity. Nearly all patients with head and neck cancer treated with radiotherapy develop some degree of mucositis, as do the majority of patients undergoing high-dose chemotherapy in conjunction with hematopoietic stem cell transplantation. Mucositis can have significant clinical and economic consequences. It is associated with severe pain that requires opioid analgesics and often results in the loss of critical functions such as speech and swallowing. Swallowing difficulties can lead to dehydration, weight loss, and the need for nutritional support. Furthermore, patients with mucositis are at increased risk of infection. Unscheduled dose reductions or treatment breaks due to severe mucositis may potentially compromise the efficacy of therapy and result in diminished quality of life. Treatment costs for patients with mucositis are substantially higher due to increased rates of hospitalization, opioid use, and a greater need for fluids and nutritional support. Costs generally increase as a function of mucositis severity. Effective treatments to prevent or reduce the incidence and severity of mucositis are needed to decrease function loss, minimize symptom burden, and lower treatment costs.

Reduced flow (oligosialia) or the complete absence of saliva (xerostomia) decrease the quality of life. While patients suffering from xerostomia are painfully aware of their condition, oligosialia all too often remains unnoticed. The causes of reduced saliva flow are manyfold: somatic or psychosomatic disease, medication, medical therapy, dehydration, age, to name a few. The respective patients suffer from thirst, difficulties in speaking (dysphonia), chewing, tasting (dysgeusia), swallowing (dysphagia) and are at a very high risk for caries as well as for bacterial, viral or fungal infections of the oral mucosa. Early diagnosis and care of oligosialia is mandatory Oral prophylactic care for and dental therapy of xerostomic patients are challenging both for the patients and the dental professionals.
