The advancement of medicine has reduced the rate of mortality and older adult population is increasing. Among the 7,700,000,000 world population in 2019, 1 in 11 people were at the age of 65 or more. The population is expected to increase to 1 in 6 people by 2050. Older adults have degenerative changes that become more severe with age. This study used the World Health Organization’s websites and PubMed and Google Scholar databases to review current global oral and systemic health issues. Studies generally reported that many older adults have no regular dental checkup. Common oral diseases such as dental caries particularly root caries and periodontal disease are highly prevalent among them. These oral diseases are often interrelated with their systemic problems. A meta-analysis reported diabetes increases the incidence and progression of periodontitis by 86%. A decrease in salivary output is common among older adults having polypharmacy. A review reported the caries risk in older adults increases by 60% with low resting pH and low stimulated salivary flow rate. Many older adults suffer from dementia and depression which complicates the delivery of dental treatment. Proper oral hygiene practice and dental care at supine position are often difficult to be carried out if they have rheumatoid arthritis. With the increasing need of elderly dental care, dentists and other dental personnel should understand interlaced oral and general health in order to provide a successful dental care plan for older adults. The aim of this study is to give an overview of the common medical conditions and dental problems and their impacts on older adults.

Objectives. (1) To determine whether manual (MTB), or electric, tooth brushing (ETB) modulates whole salivary flow rate in older adults who are free of systemic disease. (2) To determine the duration of the brushing-related modulation of salivary flow rate. (3) To compare salivary flow rate modulation associated with MTB and ETB. Method. Twenty-one adults aged 60 years and older participated in two experimental sessions during which they used a manual, or electric, toothbrush to brush their teeth, tongue, and palate. Whole salivary flow rates were determined using the draining method before, during, and after brushing. Differences in salivary flow rates across time periods, and between conditions, were examined using paired samples t-tests applying a Holm-Bonferroni sequential procedure (pcorr<0.0045). The relationship between tooth brushing and age with respect to maximum salivary flow rate increase was examined using Pearson’s correlation coefficient (p<0.05). Results/Conclusion. Whole salivary flow rates increased during, and for up to 5 minutes following, tooth brushing in adults aged 60 years and older who were free of systemic disease. The salivary effects of MTB and ETB were not significantly different. A moderate, positive correlation was observed between tooth-brushing-related maximum salivary flow rate increase and age.

Although there are numerous high protein products on the market, they are typically not designed with, or for, older consumers. This is surprising considering that dietary guidelines recognise the need for higher protein intake in later life. Protein fortified products are, however, associated with negative sensory attributes and poor consumer acceptance. This paper investigates the extent of mouthdrying sensations within a high protein solid food matrix, along with the effect of age and saliva flow. Solid models using cakes and biscuits, with or without protein fortification, were investigated. The sensory profile and physical properties were analysed and two volunteer studies (n = 84; n = 70) were carried out using two age groups (18–30; 65+). Volunteers rated individual perception and liking of products, and salivary flow rates (mL/min) were measured. Unstimulated salivary flow rates were significantly lower (p < 0.05) in older adults, although this was not found to influence product perception. Protein fortification of cakes and biscuits significantly increased (p < 0.05) perceived mouthdrying, hardness and “off” flavours, and significantly reduced (p < 0.05) melting rate, moistness and liking compared with the control versions. There is a clear need to address negative sensory attributes associated with protein fortification of cakes and biscuits to ensure product suitability for older adults.

Background: Exercise training such as balance, aerobic, and resistance training is able to improve physical functioning of older adults. Delivering such exercise regimes at home without supervision may be useful for older adults because they do not have to leave their homes. Objective: This systematic review and meta-analysis of randomized controlled trials aimed to establish the effect of unsupervised home-based exercise training regimes on physical functioning (balance and muscle strength) in older adults. Data sources: PubMed, CINAHL, Medline, Google Scholar, and Scopus databases and reference lists of included investigations were searched. Study selection: Thirteen randomized controlled trials (RCTs) of exercise training impact on balance and upper body strength with concurrent control groups were included in the analysis. Results: Our analyses revealed that in older adults, unsupervised home-based various exercise training was effective in improving measures of proactive balance (mean difference (MD) = −1.37 s; 95% confidence interval (CI), −2.24, −0.51 s; p = 0.002) and balance test battery (MD: 1.80; 95% CI, 0.46, 3.14 s; p = 0.009). There were no significant differences between the experimental and control groups for upper body strength ( p > 0.05). Conclusion: Unsupervised home-based exercise training improves balance in older adults. Future investigations are needed to clarify the mechanisms underlying unsupervised home-based exercise training’s effect on this population’s physical functioning outcomes.

Abstract Background Few studies have focused on exploring the clinical characteristics and outcomes of COVID-19 in older patients. We conducted this systematic review and meta-analysis to have a better understanding of the clinical characteristics of older COVID-19 patients. Methods A systematic search of PubMed and Scopus was performed from December 2019 to May 3rd, 2020. Observational studies including older adults (age ≥ 60 years) with COVID-19 infection and reporting clinical characteristics or outcome were included. Primary outcome was assessing weighted pooled prevalence (WPP) of severity and outcomes. Secondary outcomes were clinical features including comorbidities and need of respiratory support. Result Forty-six studies with 13,624 older patients were included. Severe infection was seen in 51% (95% CI– 36-65%, I2–95%) patients while 22% (95% CI– 16-28%, I2–88%) were critically ill. Overall, 11% (95% CI– 5-21%, I2–98%) patients died. The common comorbidities were hypertension (48, 95% CI– 36-60% I2–92%), diabetes mellitus (22, 95% CI– 13-32%, I2–86%) and cardiovascular disease (19, 95% CI – 11-28%, I2–85%). Common symptoms were fever (83, 95% CI– 66-97%, I2–91%), cough (60, 95% CI– 50-70%, I2–71%) and dyspnoea (42, 95% CI– 19-67%, I2–94%). Overall, 84% (95% CI– 60-100%, I2–81%) required oxygen support and 21% (95% CI– 0-49%, I2–91%) required mechanical ventilation. Majority of studies had medium to high risk of bias and overall quality of evidence was low for all outcomes. Conclusion Approximately half of older patients with COVID-19 have severe infection, one in five are critically ill and one in ten die. More high-quality evidence is needed to study outcomes in this vulnerable patient population and factors affecting these outcomes.
