This study demonstrates that small peptide domains derived from native protein amelogenin can be utilized to construct a mineral layer on damaged human enamel in vitro. Six groups were prepared to carry out remineralization on artificially created lesions on enamel: (1) no treatment, (2) Ca2+ and PO43- only, (3) 1100 ppm fluoride (F), (4) 20 000 ppm F, (5) 1100 ppm F and peptide, and (6) peptide alone. While the 1100 ppm F sample (indicative of common F content of toothpaste for homecare) did not deliver F to the thinly deposited mineral layer, high F test sample (indicative of clinical varnish treatment) formed mainly CaF2 nanoparticles on the surface. Fluoride, however, was deposited in the presence of the peptide, which also formed a thin mineral layer which was partially crystallized as fluorapatite. Among the test groups, only the peptide-alone sample resulted in remineralization of fairly thick (10 μm) dense mineralized layer containing HAp mineral, resembling the structure of the healthy enamel. The newly formed mineralized layer exhibited integration with the underlying enamel as evident by cross-sectional imaging. The peptide-guided remineralization approach sets the foundation for future development of biomimetic products and treatments for dental health care.

Parkinson ’s Disease is a condition characterized by degeneration of the nigrostriatal pathways resulting in marked bradykinesia. Studies have reported that nearly 25% of Medicare beneficiaries with Parkinson’s Disease reside in long-term care facilities (LTCFs). Residents of LTCFs are older and may also have other age-related mobility disorders. It is important for providers to know that Parkinsonism symptoms can also occur as a result of natural aging and will not respond to standard therapy for Parkinson’s Disease.

Atypical chest pain is of diverse origin. Typically, we initially consider cardiac etiology. When pain appears non-cardiac, there is a tendency to underestimate the illness, especially if the patient has neuropsychiatric illness. Our resident with dementia and anxiety disorder had chest pain; the diagnosis was unexpected.

Antipsychotic medications are a vital part of controlling psychosis in schizophrenic patients. However, when those patients live in nursing facilities, we are obligated by CMS to undertake gradual dose reductions of antipsychotic medication if possible. Sometimes, these efforts are successful and sometimes they fail. Antipsychotic medications have many side effects, including sedation, diabetes, hyperlipidemia, weight gain, motor rigidity, impaired gait, and falls. Monitoring of blood glucose, lipids, and extrapyramidal symptoms is mandatory.

Chronic pain is common among older adults, as is the use of medications to treat these symptoms. Aging physiology, in combination with a higher likelihood of medication use and declining renal function, makes older adults more susceptible to adverse drug effects. As such, monitoring for side effects and changes in renal function is important to avoid drug toxicity, especially during acute illness when medication errors and acute changes in renal function are more likely to occur among older adults.

Nutrition plays a vital role in the older adult, as weight in older adults is used as a marker of health and wellness. Individualization of meals is very limited; therefore, it is essential to offer a well-balanced diet options. In this regard, the national guidelines for the older adult can offer guidance to direct the meal options. There are national guidelines from the US Departments of Health and Human Services and Agriculture with dietary recommendations for community-dwelling healthy older adults.

Up to 38% of individuals with advanced dementia experience clinical depression. Although studies demonstrate lower rates of clinical depression as dementia advances, this may be attributed to the difficulty of assessment at this stage. Clinical interviews are thorough in assessing depression, though they are time- and resource-contingent. As such, healthcare providers often turn to screening tools or scales. However, conventional tools for assessing depression have problems with validity in this population.

There has been a growing emphasis towards emotional well-being in the care of older adults. This is especially important with regards to residents in a nursing home, where they can often feel marginalized or depressed. The aim of this study is to evaluate the effectiveness of pet-therapy in improving the mood and well-being in this subset of the population.

Many patients are discharged to post-acute care facilities (PACFs) following surgery. These patients have either had major surgery and require close monitoring and intensive rehabilitation, or have significant medical co-morbidities. Currently they are transported, sometimes at considerable cost, to the surgeon ’s office for post-surgery visits (PSVs). These trips can be painful and uncomfortable. A staff member from the PACF may need to accompany the patient. During PSVs surgeons observe the patient's incision(s), and assess potential complications following surgery, pain, and functional recovery.

Nursing home (NH) residents are at increased risk for malnutrition compared to community-dwelling older adults. Poor nutrition is associated with depression, functional decline, and higher 1-year mortality. Communal dining environments create a social dining atmosphere that increases the amount of food being consumed.

Background Streptococcus pneumonia is a significant cause of morbidity and mortality in adults who are immunocompromised and of advanced age. It is the standard of care to vaccinate all high-risk adults (18-64 years) and adults 65 years and older with 2 pneumococcal vaccines. However, pneumococcal immunization rates remain below the HealthyPeople2020 target goal of 90% nationally and locally.
