The Relationship

SummaryThe relationship between haematocrit and cardiovascular risk factors, particularly blood pressure and blood lipids, has been examined in detail in a large prospective study of 7735 middle-aged men drawn from general practices in 24 British towns. The analyses are restricted to the 5494 men free of any evidence of ischaemic heart disease at screening.Smoking, body mass index, physical activity, alcohol intake and lung function (FEV1) were factors strongly associated with haematocrit levels independent of each other. Age showed a significant but small independent association with haematocrit. Non-manual workers had slightly higher haematocrit levels than manual workers; this difference increased considerably and became significant after adjustment for the other risk factors. Diabetics showed significantly lower levels of haematocrit than non-diabetics. In the univariate analysis, haematocrit was significantly associated with total serum protein (r = 0*18), cholesterol (r = 0.16), triglyceride (r = 0.15), diastolic blood pressure (r = 0.17) and heart rate (r = 0.14); all at p <0.0001. A weaker but significant association was seen with systolic blood pressure (r = 0.09, p <0.001). These relationships remained significant even after adjustment for age, smoking, body mass index, physical activity, alcohol intake, lung function, presence of diabetes, social class and for each of the other biological variables; the relationship with systolic blood pressure was considerably weakened. No association was seen with blood glucose and HDL-cholesterol. This study has shown significant associations between several lifestyle characteristics and the haematocrit and supports the findings of a significant relationship between the haematocrit and blood lipids and blood pressure. It emphasises the role of the haematocrit in assessing the risk of ischaemic heart disease and stroke in individuals, and the need to take haematocrit levels into account in determining the importance of other cardiovascular risk factors.

In accordance with the requirements of paragraph 3.2.6 of sanitary rules and norms «Sanitary and epidemiological requirements for physical factors at workplace», in the event of exceeding noise level at workplace above 80 dBA, an employer is obliged to assess the health risk of workers and confirm an acceptable risk to their health. The connection between the incidence of occupational and occupationally conditioned diseases with noise exposure exceeding the maximum permissible levels (80 dBA) was estimated. The assessment was carried out at a food industry enterprise of Perm Region. Assessing the relationship between morbidity and noise exposure is the first step in evaluation of occupational health risks for workers exposed to noise exceeding MAL. If a reliable relationship between morbidity and noise exposure is established, an assessment of occupational risk is conducted. The odds ratio (OR) for diseases characterized by high blood pressure and disorders of autonomic nervous system was <1 (confidence interval CI=0.11–1.61 and CI=0.08–2.78, respectively). The relative risk (RR) for diseases characterized by high blood pressure and disorders of autonomic nervous system was <1. The received data testify absence of connection of morbidity with exposure to industrial noise, calculation of etiological share of responses and levels of risk is not required.

Abstract Background In neurocritically ill patients, one early mechanism behind secondary brain injury is low systemic blood pressure resulting in inadequate cerebral perfusion and consequent hypoxia. Intuitively, higher partial pressures of arterial oxygen (PaO2) could be protective in case of inadequate cerebral circulation related to hemodynamic instability. Study purpose We examined whether the association between PaO2 and mortality is different in patients with low compared to normal and high mean arterial pressure (MAP) in patients after various types of brain injury. Methods We screened the Finnish Intensive Care Consortium database for mechanically ventilated adult (≥ 18) brain injury patients treated in several tertiary intensive care units (ICUs) between 2003 and 2013. Admission diagnoses included traumatic brain injury, cardiac arrest, subarachnoid and intracranial hemorrhage, and acute ischemic stroke. The primary exposures of interest were PaO2 (recorded in connection with the lowest measured PaO2/fraction of inspired oxygen ratio) and the lowest MAP, recorded during the first 24 h in the ICU. PaO2 was grouped as follows: hypoxemia (< 8.2 kPa, the lowest 10th percentile), normoxemia (8.2–18.3 kPa), and hyperoxemia (> 18.3 kPa, the highest 10th percentile), and MAP was divided into equally sized tertiles (< 60, 60–68, and > 68 mmHg). The primary outcome was 1-year mortality. We tested the association between hyperoxemia, MAP, and mortality with a multivariable logistic regression model, including the PaO2, MAP, and interaction of PaO2*MAP, adjusting for age, admission diagnosis, premorbid physical performance, vasoactive use, intracranial pressure monitoring use, and disease severity. The relationship between predicted 1-year mortality and PaO2 was visualized with locally weighted scatterplot smoothing curves (Loess) for different MAP levels. Results From a total of 8290 patients, 3912 (47%) were dead at 1 year. PaO2 was not an independent predictor of mortality: the odds ratio (OR) for hyperoxemia was 1.16 (95% CI 0.85–1.59) and for hypoxemia 1.24 (95% CI 0.96–1.61) compared to normoxemia. Higher MAP predicted lower mortality: OR for MAP 60–68 mmHg was 0.73 (95% CI 0.64–0.84) and for MAP > 68 mmHg 0.80 (95% CI 0.69–0.92) compared to MAP < 60 mmHg. The interaction term PaO2*MAP was nonsignificant. In Loess visualization, the relationship between PaO2 and predicted mortality appeared similar in all MAP tertiles. Conclusions During the first 24 h of ICU treatment in mechanically ventilated brain injured patients, the association between PaO2 and mortality was not different in patients with low compared to normal MAP.

The association between blood pressure measured at home and handgrip strength in patients with diabetes has not been investigated. Therefore, in this study, we aimed to assess this association among patients with type 2 diabetes. In this cross-sectional study, 157 patients with type 2 diabetes underwent muscle tests and morning and evening blood-pressure measurements at home in triplicate for 14 consecutive days throughout the study period. Univariate and multivariate regression analyses were conducted to analyze the relationship between home blood-pressure parameters and handgrip strength. The average age and hemoglobin A1c of the patients were 70.5 years and 7.1%, respectively. Morning diastolic blood pressure of [β (95% confidence interval; CI): 0.20 (0.03, 0.37)] was associated with handgrip strength in men, while morning systolic blood pressure of [−0.09 (−0.15, −0.04)], morning pulse pressure of [−0.14 (−0.21, −0.08)], and evening pulse pressure of [−0.12 (−0.19, −0.04)] were associated with handgrip strength in women. Home-measured blood pressure was associated with handgrip strength. Sex differences were found in the relationship between home blood-pressure parameters and handgrip strength.

Blood pressure (BP) follows a circadian rhythm, it increases on waking in the morning and decreases during sleeping at night. Disruption of the circadian BP rhythm has been reported to be associated with worsened cardiovascular and renal outcomes, however the underlying molecular mechanisms are still not clear. In this review, we briefly summarized the current understanding of the circadian BP regulation and provided therapeutic overview of the relationship between circadian BP rhythm and cardiovascular and renal health and disease.

Abstract Introduction The sodium voltage-gated channel alpha subunit 7 (SCN7A) has been associated to renal Na regulation and hypertension. This study explores the relationship between blood pressure (BP) and urinary overnight Na/K ratio (UONaK) in hypertensives (HT) and normotensive (NT) subjects from from National Heart, Lung and Blood Institute funded, Family Blood Pressure Program (FBPP) that were genotyped for 3 SNPs for SCN7A: CV2161217, CV 356958 and CV433036. Hypothesis Genetic variations in the SCNA7 are differently associated to BP and UONaK in HT and NT. Methods 1,749 subjects genotyped for SCN7A SNPs CV2161217, CV 356958 and CV433036 were analyzed from FBPP. Subjects with diastolic BP (DBP) ≥80 or systolic BP (SBP) ≥130 mmHg were classified HTN; subjects with SBP &lt;130 and DBP &lt;80 mmHg were classified as NT. UONAK was calculated by dividing overnight Na by K concentration. Correlation analysis done with partial variables (use of antihypertensive drug, use of diuretics, overnight urine creatinine). Results For the CV2161217, HTN group (n=1,030), 52% had C/C, 39% C/T and 9% T/T. In NT group (n=719), 52% had C/C, 38% C/T and 10% T/T. In the HT group, subjects with CC genotype showed strong correlation between DBP and UONaK (Fig 1a) while no significant correlation with SBP. Those with CT genotype maintained the correlation between SBP and UONaK (r=0.10, p=0.03) with no correlation with SBP. The TT showed no correlation between UONaK and SBP or DBP. In the NT, subjects with TT genotype showed strong correlation between DBP and UONaK (Fig 1b) and with SB (r=0.256, p=0.03). Those with CT or TT genotypes showed no correlation between UONaK and SBP or DBP. Similar finding were obtained for CV356958 SNP; no similar association was observed in the CV433036 SNP. Conclusions Subjects with the genetic variations in the SCNA7, such as CV2161217 and CV 356958 SNPs, showed significant correlation between blood pressure and overnight urinary sodium potassium. This finding could have important implications in non dipping status observed in some hypertensive patients. Funding Acknowledgement Type of funding source: None
