Background. Recent studies suggest that the daily intake of lemon (Citrus limon) has a good effect on health, but this has not been confirmed in humans. In our previous studies, it was observed that people who are conscious of their health performed more lemon intake and exercise. An analysis that took this into account was required.Methodology. For 101 middle-aged women in an island area in Hiroshima, Japan, a record of lemon ingestion efforts and the number of steps walked was carried out for five months. The change rates (Δ%) of the physical measurements, blood test, blood pressure, and pulse wave measured value during the observation period were calculated, and correlations with lemon intake and the number of steps walked were considered. As a result, it was suggested that daily lemon intake and walking are effective for high blood pressure because both showed significant negative correlation to systolic blood pressure Δ%.Conclusions. As a result of multiple linear regression analysis, it was possible that lemon ingestion is involved more greatly with the blood citric acid concentration Δ% and the number of steps with blood pressure Δ%, and it was surmised that the number of steps and lemon ingestion are related to blood pressure improvement by different action mechanisms.

Abstract BACKGROUND The phenotype of diabetic kidney disease represents a lower estimated glomerular filtration rate (eGFR) and albuminuria. We investigated the association between day-by-day home blood pressure (BP) variability and the eGFR in subjects with diabetes and compared this association with that in subjects without diabetes. We then attempted to determine whether the association is present in albuminuria. METHODS We analyzed 4,231 patients with risk factors of cardiovascular disease (24.4% with diabetes) from the J-HOP (Japan Morning Surge-Home Blood Pressure) study. Home BP was measured in the morning and evening for 14 days. We calculated the SD, coefficient of variation, average real variability (ARV), and variation independent of the mean of the subjects’ morning and evening home systolic BP (SBP) as the indexes of day-by-day home BP variability. RESULTS A multiple linear regression analysis adjusted for covariates showed both average morning and evening SBP were associated with the log-transformed urine albumin-to-creatinine ratio (UACR) with and without diabetes (all P < 0.05), but not with the eGFR except for an association of average evening SBP in the no-diabetes group. None of the indexes of day-by-day morning and evening home SBP variability were associated with the log-transformed UACR except for the association between the ARV of home morning SBP in the diabetes group. All of the indexes of day-by-day morning and evening home SBP variability were associated with the eGFR only in the diabetes group (all P < 0.05). CONCLUSIONS The association between increased day-by-day home BP variability and impaired renal function was unique in diabetes.

SUMMARY OBJECTIVES To compare the serum concentrations of adipokines resistin and chemerin in children and adolescents with eutrophic and overweight and to evaluate their relationship with anthropometric, biochemical, and blood pressure variables. METHODS a cross-sectional epidemiological study was conducted with 234 students enrolled in public elementary schools in the city of Juiz de Fora / MG. Anthropometric evaluation, biochemistry, and blood pressure measurement were performed. Statistical analyzes included the Student-t or Mann-Whitney tests, Pearson or Spearman correlation, used according to the distribution of the variables, and linear regression analysis, by means of the evaluation of the effect of the independent variables on the serum levels of chemerin and resistin, adjusted for age and sex. For the data analysis, SPSS® software version 21.0 and STATA® version 10.1 were used, assuming a significance level of 5%. RESULTS the concentrations of chemerin were higher in eutrophic individuals than in those with excess weight (p> 0.05). In contrast, levels of resistin were higher in the young with excess weight than in the eutrophic ones (p <0.05). In the multiple linear regression analysis, the levels of chemerin were associated with the values of resistin, systolic, and diastolic blood pressure. Resistance levels maintained association only with BMI and chemerin values. CONCLUSION the adipokines analyzed presented a distinct profile in the groups of children and adolescents with eutrophic and overweight.

The purpose of this study was to evaluate the effect of slow breathing and prehypertension (PHT) on cardiovascular and HRV variables and on the Valsalva ratio (VR). ECG was recorded in 39 normotensives and 35 prehypertensives at 5 min resting and slow breathing (6 breaths/min) stages to obtain HR, LF and HF power; SBP and DBP were recorded at the end of each stage. The Valsalva manoeuvre was performed after resting and slow breathing stages. Two-way repeated MANOVA was used to test for the effects of PHT and slow breathing. Stepwise multiple linear regression analysis was used to reveal predictors of HR, SBP and DBP. The normotensives and the prehypertensives demonstrated reduction of SBP during slow breathing (117.95 ± 0.73 vs. 115.18 ± 0.91 mm Hg, P = 0.001 and 130.09 ± 0.08 vs. 125.91 ± 0.96 mm Hg, P < 0.001, respectively). At rest, the VR was lower in prehypertensives (1.69 ± 0.05 vs. 1.87 ± 0.05, P = 0.009). After slow breathing, the VR increased significantly only in prehypertensives (P = 0.008), it was no longer different from that of normotensives (1.82 ± 0.06 vs. 1.90 ± 0.06, P = 0.346). The LnLF power, interpreted according to our hypothesis described previously as sympathoinhibition, increased in both groups. Slow breathing reduced SBP in normotensives and prehypertensives as a result of an increase in sympathoinhibition in both groups and VR, considered as a surrogate marker of the baroreflex activity, in prehypertensives.

Abstract Background To investigate blood pressure variability among 3 successive blood pressure measurements in an unselected nationwide population in China. Methods A total of 77,549 participants were included from measurements in May 2017 in China. Blood pressure was measured 3 times consecutively with a half minute interval. Blood pressure variability was estimated with the standard deviation and coefficient of variation of the systolic and diastolic blood pressure. Results Not all participants showed a decreasing trend with increasing number of measurements. In fact, 14% of the participants showed at least 5 mm Hg increase in systolic blood pressure. The coefficient of variation of systolic and diastolic blood pressure in women was higher than in men [(4.2 ± 3.3)% vs. (4.1 ± 3.3)%, (4.7 ± 4.0)% vs. (4.6 ± 4.1)%; P &lt; 0.05]. The differences were significant (P &lt; 0.01) among different groups of age and blood pressure levels. Multiple linear regression analysis showed that the systolic blood pressure variability indexes were inversely associated with age but positively associated with the level of the first systolic blood pressure reading (P &lt; 0.01). The systolic blood pressure standard deviation and coefficient of variation in females were higher than in males (P &lt; 0.01). Conclusions Not all subjects demonstrate a decreasing trend with increasing number of blood pressure measurements. Within-visit blood pressure variability varies with age, gender, and blood pressure.

Abstract We compared the perception of two ethnic groups in relation to health, obesity and blood pressure problems and its management, and to compare the body fat patterning and blood pressure levels between Rai and Lepcha ethnic groups. We chose Rai and Lepcha ethnic groups living in Ranka, a place which is 16 kilometres away from the city of Gangtok, Sikkim. The study involved 160 males (Rai = 80 and Lepcha = 80) of age 25–35 years. The participants were initially interviewed about their perception towards health, obesity and blood pressure problems and its management along with other socio-demographic and lifestyle variables. Later, body fat patterning and blood pressure levels of the participants were measured and compared between these two groups. Multiple linear regression analysis was performed to understand the association of body fat patterning and blood pressure levels with socio-demographic and lifestyle variables. Multivariate analysis of covariance (MANCOVA) was used to examine the relationship of ethnicity with both body fat patterning and blood pressure levels. We found a noticeable difference between Lepcha and Rai ethnic groups in perception towards health and obesity, blood pressure problems and its management. Similarly, a significant difference was observed in body fat patterning and blood pressure levels between Rai and Lepcha participants. MANCOVA revealed that the measures of body fat pattering and blood pressure levels differed significantly between these two ethnic groups, after controlling for lifestyle variables and age of the participants at time of interview. We concluded that there remains ethnic diversity, embedded in cultural behaviours and practices concerning health and obesity, hypertension and associated lifestyle patterns. Such practices, rooted in the belief system of an ethnic group is likely to inform the health condition of group members.

Background: In the face of COVID-19, healthcare workers need to cope with the ongoing stressors at play and keep psychological distress at a minimum level. This study examined the psychosocial and demographic factors associated with nurse's resilience in the hospitals of Ahvaz that is one of the top cities infected with COVID-19 in Iran.Methods: The present cross-sectional study was conducted on 387 Iranian nurses in Ahvaz city. For data collection purposes, three online questionnaires (including Copenhagen Psychosocial, Demographic, and Connor–Davidson Resilience Scale) were distributed among the participants.Results: The mean resilience score was equal to 61.8 ± 14.8 for 387 nurses. Resilience had a statistically significant negative correlation with quantitative demand (r = −0.273, P &lt; 0.008), work pace (r = −0.262, P &lt; 0.011), emotional demand (r = −0.226, P &lt; 0.030), stress (r = −0.458, P &lt; 0.000), and burnout (r = −0.287, P &lt; 0.005). Multiple linear regression analysis indicated that stress, job satisfaction, burnout and age were the main predictors of nurses' resilience during the (COVID-19) pandemic (R2 = 0.45).Conclusions: We identified psychosocial and demographic predictive factors that may contribute to greater resilience among nurses during the COVID-19 outbreak. The findings of this study can be used to implement psychosocial interventions to amplify the resilience of medical staff during the COVID-19 outbreak.

Recently, insular cortex (Ic) is suggested to be a key site in limbic-autonomic integration. Association of Ic damage with diurnal blood pressure (BP) variation disruption, higher level of brain natriuretic peptide (BNP) and catecholamine were reported. We examined the relationship of Ic volume with ambulatory BP measures and these biomarkers. Amubulatory BP monitoring and brain MRI were performed in 55 elderly hypertensives. Right and left Ic volumes were measured using Intensity Contour-Mapping Algorithm. BNP, adrenaline and noradrenaline concentration were evaluated. Subjects were classified into Ic-atrophy group (n=14) and non-atrophy group (n=41) based on total Ic volume (right and left side) of 12.6 cm 3 (lowest quartile). In Ic-atrophy group, 24hr (144.5 vs 134.2 mmHg, p=0.032), sleep (143.4 vs 127.2 mmHg, p=0.002) systolic BP (SBP), nocturnal SBP dipping (1.30 vs 8.54 %, p=0.027) and BNP (60.6 vs 28.1 pg/ml, p=0.008) were significantly, and noradrenaline (373.5 vs 296.5 pg/ml, p=0.084) was marginally different from those in non-atrophy group. Right Ic volume was significantly correlated with 24hr (r=−0.271, p=0.046), sleep (r=−0.420, p=0.001) SBP, nocturnal SBP dipping (r=0.311, p=0.021) and noradrenaline (r=−0.334, p=0.013), while left Ic volume with 24hr (r=−0.279, p=0.039), sleep (r=−0.498, p=0.0001) SBP, nocturnal SBP dipping (r=0.409, p=0.002) and BNP (r=−0.363, p=0.006). In multiple linear regression analysis adjusted for age, gender and body mass index, left Ic volume was significantly negatively associated with sleep SBP (p=0.008) and BNP (p=0.001), and positively with nocturnal SBP dipping (p=0.044). In elderly hypertensives, predominant left Ic atrophy was significantly associated with sleep SBP measures and BNP. Ic damage, specifically in the left side, may partly contribute to disruption of diurnal ambulatory BP rhythm as well as cardiac function via central autonomic dysregulation.

Aim.Smoking is a major risk factor for diabetes mellitus, mainly due to decreased insulin secretion and increased insulin resistance. However, there has been little research on the effects of smoking cessation period on changes in insulin resistance. In this study, we investigated the relationships between the length of time since smoking cessation period and insulin resistance in asymptomatic Korean male ex-smokers.Methods.A total of 851 male adults were included in this study. We considered several factors that can affect insulin resistance, and through multiple linear regression analysis, we assessed the effect the length of time since smoking cessation on insulin resistance in ex-smokers. Insulin resistance was represented as the insulin resistance index estimated by homeostasis model assessment.Results. HOMA-IR values showed a statistically significant negative correlation with the length of time since smoking cessation (p=0.009) in ex-smokers. After performing multiple linear regression analysis using factors that could potentially influence insulin resistance, we found that waist circumference (p=0.026) and the length of time since smoking cessation (p=0.039) were independent predictors of HOMA-IR in asymptomatic male ex-smokers.Conclusion. The longer the smoking cessation period, the more the insulin resistance tended to decrease in asymptomatic Korean male ex-smokers.

In Saudi Arabia, data regarding salt-related knowledge and practices are still lacking. This cross-sectional study aimed to investigate salt-related knowledge and practices and associated factors in Saudi adults. Data on the following variables were collected from 467 participants living in Madinah or Jeddah via face-to-face interviews: demographics, anthropometrics (height and weight), blood pressure (assessed using a digital sphygmomanometer), salt-related knowledge, and practices related to salt intake. Salt-related knowledge and practices were limited among the study participants; however, they were not correlated (rs = 0.10). Multiple linear regression analysis revealed that salt-related practices were negatively associated with sodium intake and positively associated with body mass index (BMI) (p < 0.001 and p = 0.001, respectively), whereas salt-related knowledge was not associated with sodium intake, blood pressure, or BMI. Salt-related knowledge is limited and not linked to practices related to salt intake in Saudi adults. Interventions are needed to increase the accessibility of low-sodium food options and improve practices limiting sodium intake to prevent the occurrence of salt-related diseases among adults in Saudi Arabia.
