Article Abstract
Background: Obesity, depressive symptoms, and periodontitis are major worldwide health concerns. Despite separate studies on both illnesses, no research has directly examined the link between depressive symptoms and periodontitis in obese people. Given the close correlation between obesity and chronic illnesses, as well as the possibility of a bidirectional impact between depressive symptoms and periodontitis, this study aims to investigate the link between depressive symptoms and periodontitis in an obese population.
Methods: This study analyzed data from the NHANES database (2009-2014), including 4,820 persons aged 30 years or older with a BMI over 30. The severity of periodontitis was assessed by clinical attachment loss and probing depth, while symptoms of depressive symptoms were measured using the PHQ-9 questionnaire. After gender, age, race, education, ratio of family income to poverty, sleep duration, diabetes, and cardiovascular illnesses were controlled for, the independent connection between depressive symptoms and periodontitis was investigated using multivariable logistic regression.
Results: The modified models indicated a significant negative correlation between depressive symptoms and periodontitis (effect size: -0.13, 95% CI: -0.24 to -0.01, p = 0.0266), indicating that depressive symptoms may operate as a protective factor against periodontitis. Interaction studies did not indicate substantial impact modification by factors like age, gender, or education level.
Conclusion: This study is the first investigation demonstrating a negative link between depressive symptoms and periodontitis in obese persons, indicating a significant interaction between mental health and dental health in this demographic. The results highlight the importance of comprehensive psychological and oral health care in obese individuals, providing a new avenue for future research and therapeutic applications.

Major depressive disorder is a prevalent and debilitating psychiatric illness that produces significant disability. Clinical data suggest that the pathophysiology of depression is due, in part, to a dysregulation of inflammation and glutamate levels in the brain. The systemic administration of lipopolysaccharide (LPS) has been shown to induce depressive-like behaviors in mice.

Anxiety and depression symptoms and disorders are the leading child mental health problems in western societies. This systematic review evaluated how parental emotion socialization (ES) relates to children's internalizing problems (from birth to age 18 years). Three meta-analyses, evaluating supportive ( = 50, = 10,698), nonsupportive ES behaviors ( = 47, = 10,970), and elaboration ( = 6, = 867) were conducted.

Objective: One of the most frequent neuropsychiatric complications after a stroke is poststroke depression (PSD). However, it is unclear whether disparities exist in PSD diagnosis. The authors examined a 10-year trend in PSD by socioeconomic and clinical characteristics.

Objective: The authors examined differences in resting-state functional connectivity (rsFC) in the brain between nontreatment-seeking adults with alcohol use disorder (case group) and recreational drinkers without alcohol use disorder (control group) and explored behavioral and psychological mechanisms underlying these differences.
Methods: This case-control study included 140 adults (N=71 with alcohol use disorder and N=69 demographically matched control individuals) who completed a 9-minute resting-state functional MRI scan. About 45% were men, and the mean±SD age was 32.

ancreatic cancer is an aggressive disease and often presents at an advanced stage with no curative options. The disease is often characterized by rapid progression, limited or short-lived responsiveness to standard therapies, and a profound impact on patients' quality of life. Despite advances in targeted therapies and immunotherapy, curative outcomes remain elusive for the majority of patients with advanced or high-grade disease with a 5-year survival rate of less than 10%.
