Data on the oral health of the elderly depict a worrying situation, with an elevated prevalence of caries and moderate periodontal disease, frequent edentulism, and numerous cases of dry mouth and oral cancer. There is wide evidence that periodontitis is a risk factor for certain systemic diseases, and impaired oral health has been associated with mastication and nutritional problems, especially among the elderly, with highly negative effects on their quality of life. In this nonsystematic review, the authors discuss the importance of evaluating the oral health of the geriatric population in a comprehensive manner, beyond simple clinical assessments.

Adherence to therapy, defined as the extent to which a patient follows prescribed therapeutic recommendations, is a pivotal factor in the effective management of chronic diseases such as diabetes, hypertension, and cardiovascular conditions. This review highlights the profound influence of adherence on clinical outcomes, healthcare costs, and patient quality of life. Despite its critical importance, non-adherence remains a pervasive challenge globally, contributing to suboptimal treatment results, higher rates of complications, increased hospitalizations, and substantial healthcare expenditures. This narrative review examines the multifaceted impact of adherence, focusing on its role in achieving clinical efficacy, mitigating economic burdens, and enhancing patient well-being. The findings reveal that poor adherence exacerbates the risk of disease progression, complications, and higher healthcare costs. Conversely, improved adherence promotes better disease control, fewer complications, and enhanced patient quality of life. Interventions such as patient education, streamlined treatment regimens, and the integration of digital health tools have shown promise in addressing adherence barriers. Furthermore, the role of healthcare professionals is underscored as fundamental, with their continuous support, effective communication, and efforts to build patient trust being essential to fostering better adherence. In conclusion, adherence significantly affects clinical outcomes, healthcare costs, and patient quality of life. Addressing barriers to adherence requires a comprehensive and personalized approach, considering individual patient needs and circumstances. Future research should prioritize the long-term evaluation of emerging technologies and the development of tailored strategies to improve adherence across diverse patient populations. Strengthening adherence is not only crucial for individual patient outcomes, but also for enhancing the sustainability and efficiency of healthcare systems.

Background: Dementia is a multi‐etiologic syndrome characterized by multiple cognitive deficits but not always by the presence of cognitive impairment. Cognitive impairment is associated with multiple non‐modifiable risk factors but few modifiable factors. Epidemiologic studies have shown an association between periodontitis, a potentially modifiable risk factor, and cognitive impairment. The objective of this study is to determine whether clinical periodontitis is associated with the diagnosis of cognitive impairment/dementia after controlling for known risk factors, including age, sex, and education level.Methods: A case‐control study was conducted in Granada, Spain, in two groups of dentate individuals aged >50 years: 1) cases with a firm diagnosis of mild cognitive impairment or dementia of any type or severity and 2) controls with no subjective memory loss complaints and a score >30 in the Phototest cognitive test (screening test for cognitive impairment). Periodontitis was evaluated by measuring tooth loss, plaque and bleeding indexes, probing depths, and clinical attachment loss (AL).Results: The study included 409 dentate adults, 180 with cognitive impairment and 229 without. A moderate and statistically significant association was observed between AL and cognitive impairment after controlling for age, sex, education level, oral hygiene habits, and hyperlipidemia (P = 0.049). No significant association was found between tooth loss and cognitive impairment.Conclusion: Periodontitis appears to be associated with cognitive impairment after controlling for confounders such as age, sex, and education level.

The Mediterranean Diet (MedDiet) is a healthy dietary pattern which has been related to a lower risk of certain chronic diseases, such as some cancers. However, its role in breast cancer development remains unclear. This umbrella review aims to summarize the highest available evidence on MedDiet and breast cancer risk. Pubmed, Web of Science, and Scopus electronic platforms were searched for relevant systematic reviews and meta-analyses. The selection criteria included systematic reviews with or without meta-analysis including women aged 18 years or older which evaluated the adherence to a MedDiet as the exposure and incidence of breast cancer as the outcome variable. Overlapping and quality of the reviews using AMSTAR-2 tool were independently assessed by two authors. Five systematic reviews and six systematic reviews with meta-analysis were included. Overall, 4 systematic reviews - two with and two without meta-analysis - were rated as of high quality. An inverse association was found in 5 of the 9 reviews which evaluated the role of MedDiet on the risk of total breast cancer. The meta-analyses showed moderate-high heterogeneity. The risk reduction seemed to be more consistent among postmenopausal women. No association was found for MedDiet among premenopausal women. The results of this umbrella review suggest that adherence to a MedDiet pattern had a protective effect on the risk of breast cancer, especially for postmenopausal breast cancer. The stratification of breast cancer cases and conducting high-quality reviews are aspects needed to overcome the current results' heterogeneity and to improve knowledge in this field.
