Evaluation of relationship between markers of inflammation and blood pressure in subjects attending OPD in a tertiary care center in Chennai

Background: The incidence and prevalence of hypertension have been increasing steadily in the present era. Inflammation is a proven key factor in the pathogenesis of hypertension. C-reactive protein (CRP) is a known marker of vascular inflammation leading to hypertension. High-sensitivity CRP (hs-CRP) is a sensitive marker of assessment of inflammatory changes before the rise in CRP. Aims and Objectives: The goal of this study was to decipher the stage at which inflammation starts related to changes in hypertension using CRP as well as hs-CRP. Materials and Methods: This is a cross-sectional study which included 120 individuals, who were subdivided into three groups - Normotensive: 40, pre-hypertensive: 40, and hypertensive. JNC classification was used for the categorization of blood pressure. hs-CRP was analyzed as per the principle of ELISA. Results: There was a significant difference in hs-CRP between normotensive and hypertensive. A strong association between hypertension, CRP, and hs-CRP was found. Conclusion: hs-CRP is a sensitive marker for early assessment of inflammatory components in hypertension.

Effects of forest bathing on pre-hypertensive and hypertensive adults: a review of the literature

The aim in this literature review was (1) to explore the physiologically and psychologically therapeutic benefits of forest bathing on adults suffering from pre-hypertension or hypertension, and (2) to identify the type, duration, and frequency of an effective forest bathing intervention in the management of pre-hypertension and hypertension, so as to provide directions for future interventions or research. The electronic databases PubMed, Cochrane Library, CINAHL, PsyINFO, and the China Academic Journals (CAJ) offered through the Full-text Database (CNKI) were searched for relevant studies published from the inception of the databases to April 2019. Of the 364 articles that were identified, 14 met the criteria for inclusion in this review. The synthesis of the findings in the included studies revealed that forest bathing interventions were effective at reducing blood pressure, lowering pulse rate, increasing the power of heart rate variability (HRV), improving cardiac-pulmonary parameters, and metabolic function, inducing a positive mood, reducing anxiety levels, and improving the quality of life of pre-hypertensive or hypertensive participants. Forest walking and forest therapy programs were the two most effective forest bathing interventions. Studies reported that practicing a single forest walking or forest therapy program can produce short-term physiological and psychological benefits. It is concluded that forest bathing, particularly forest walking and therapy, has physiologically and psychologically relaxing effects on middle-aged and elderly people with pre-hypertension and hypertension.
