Influence of Oral Dipping Tombak Smokeless Tobacco on Coagulation Profile and Platelet Counts. Hematol Rep 2022; 14:126-134. [PMID: 35466183 PMCID: PMC9036225 DOI: 10.3390/hematolrep14020019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 02/24/2022] [Accepted: 03/28/2022] [Indexed: 11/16/2022] Open
Abstract
The goal of this paper is to investigate the influence of oral dipping of Tombak Smokeless Tobacco (SLT) on prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio(INR) values, and platelet counts (PLTs), in Sudanese Tombak users. An analytical cross-sectional study was conducted at Kosti health insurance hospital, Sudan, in 2019. According to the inclusion and exclusion criteria, 100 adult users of oral Tombak for three or more years were chosen randomly as a study group. Another 100 matched healthy individuals who never used Tombak were randomly selected as a comparative group. Venous blood specimens were collected in ethylene diamine tetra-acetic acid (EDTA) containers for the PLT counts using the automated haematology analyser (Sysmex, Tokyo, Japan XK-21SYSMEX) and in trisodium citrate anti-coagulant containers for coagulation tests using a co-agulometer machine analyser. Our findings show a significant decrease in PLT count mean values in the Tombak users group (212.1 × 103/mm3 ± 74.3 × 103/mm3) compared with the non-taking Tombak group mean values (243.2 × 103/mm3 ± 83.0 × 103/mm3), (p < 0.006). Both PT and APTT were significantly prolonged in Tombak users (16.03 ± 1.22 s vs. 14.44 ± 0.557 s), p < 0.001 for PT, and (41.62 ± 7.28 s vs. 34.99 ± 4.02 s), (p < 0.001) for APTT. INR mean values were significantly longer in Tombak users (1.11 ± 0.096) vs. (1.07 ± 0.66; p < 0.001). Multiple linear regression analysis findings show a significant impact of the four investigated variables, including duration of taking Tombak, age, and frequency of taking Tombak per day (p < 0.001). In conclusion, using Tombak a Smokeless Tobacco (SLT) for a long period significantly affect Platelet counts and coagulation profile.

Abstract
PM2.5-related neurological and mental diseases, such as cognitive impairment and stroke, tend to cause disability. Six-week-old male C57BL/6 mice were divided into 6 groups and exposed to concentrated PM2.5 or filtered air for 2, 4, and 6 months, respectively. The neurobehavioral changes of mice were tested. The weight of the whole brain and olfactory bulbs were recorded at the end of exposure, and the brain structure was observed by hematoxylin and eosin (HE) staining. Serum indicators, mRNA, and protein expressions were detected. The spatial learning memory ability was impaired, and the mice were more anxious after PM2.5 exposure. Relative brain weight decreased with age, and PM2.5 exposure exceeded the decrease of relative brain weight. Interestingly, superoxide dismutase (SOD) and albumin decreased in the PM2.5-exposed groups although neuronal morphology and other serum indicators did not show significant difference between PM and FA groups. Moreover, PM2.5 induced the increase of plasminogen at 2 months but recovered at 4 months and then increased at 6 months again. The results from protein expression and transcriptomic test demonstrated that PI3K/AKT/FoxO1 pathway might be activated after 6-month PM2.5 exposure in mice. Indicators albumin, the percentage of albumin over IgG (A/G value), and plasminogen were the main serous changes in mice after early-stage (2 months) and long-term (6 months) PM2.5 exposure. In addition, early-stage injury induced by PM2.5 might recover at later time point and display significant injury again with the exposure time. PM2.5 exposure-induced brain injury might be associated with the activation of PI3K/AKT/FoxO1 pathway.

Abstract
Objectives: To study the effects of heavy cigarette smoking on coagulation (CGG) screening tests and platelet counts (PLTs) in a Sudanese male adults population. Methods: A case control study was conducted at both Kosti and Gabalein towns, Sudan, during October 2016 to May 2017. A 100 adult cigarette smokers were selected and another 100 matched non-smokers were selected as healthy controls. Blood samples were collected in trisodium citrate anti-coagulant for prothrombin time (PT), partial thromboplastin time (PTT), and international normalized ratio (INR), analyzed using standard methods (co-agulometer machine) and Ethylenediaminetetraacetic acid for the platelet counts, using an automated haematology analyzer (Sysmex, Tokoyo, Japan). Results: The results showed that the mean platelet counts were significantly lower in the smokers (183x103/cmm±64x103/cmm) versus (244x103/cmm±38x103/cmm) in non-smokers, (p<0.000). Pearson correlation analysis suggested a weak negative correlation between platelet counts with the duration of smoking (r= -0.289, p<0.004) and the age of the smokers (r= -0.238, p<0.017). The mean PT and INR were also significantly lower in smokers (12.9±1.2 seconds) compared with the non-smokers (13.7±1.04 seconds, p<0.000), for PT and (0.95±0.09 versus 1.01±0.08, p<0.000) for INR. In contrast, PTT had no significant variation in smokers (30.5±3.8 seconds) and the non-smokers (37.9±4.6 seconds). A p-value>0.05 was considered significant. Conclusion: Cigarette smokers tend to have lower platelet counts, shorter PT, and INR values, compared to non-smokers. Therefore, smoking might be associated with bleeding disorders but further investigations are needed.

Abstract
Systemic inflammation has been proposed as a physiological process linking socio-economic position (SEP) to health. We examined how SEP inequalities in inflammation -assessed using C-reactive protein (CRP) and fibrinogen- varied across the adult age span. Current (household income) and distal (education) markers of SEP were used. Data from 7,943 participants (aged 25+) of Understanding Society (wave 2, 1/2010-3/2012) were employed. We found that SEP inequalities in inflammation followed heterogeneous patterns by age, which differed by the inflammatory marker examined rather than by SEP measures. SEP inequalities in CRP emerged in 30s, increased up to mid-50s or early 60 s when they peaked and then decreased with age. SEP inequalities in fibrinogen decreased with age. Body mass index (BMI), smoking, physical activity and healthy diet explained part, but not all, of the SEP inequalities in inflammation; in general, BMI exerted the largest attenuation. Cumulative advantage theories and those considering age as a leveler for the accumulation of health and economic advantages across the life-span should be dynamically integrated to better understand the observed heterogeneity in SEP differences in health across the lifespan. The attenuating roles of health-related lifestyle indicators suggest that targeting health promotion policies may help reduce SEP inequalities in health.

Abstract
OBJECTIVE Confirmation of the association between smoking status and biological inflammatory or anticoagulant markers is required in the field of occupational therapy to promote anti-smoking education. The associations between the smoking status and biological markers were clarified. METHODS The study was performed in 5102 working men aged 30-60 years old. The author measured the plasma fibrinogen, white blood cell count (WBC) and serum high-sensitivity C-reactive protein (CRP) as biomarkers of the smoking status. RESULTS After adjustment for age, the mean plasma fibrinogen level in never-smokers was significantly lower than that in current smokers. The mean WBC count was also significantly lower in the never-smokers than that in current smokers and ex-smokers who had quit within the previous 1 year. Furthermore, the mean log-transformed serum CRP value in never-smokers was significantly lower than that in current smokers smoking ≥20 cigarettes daily. Spearman's rank correlation coefficients between the plasma fibrinogen and the serum CRP and WBC were 0.561 and 0.243, respectively. The mean plasma fibrinogen, serum CRP and WBC count in the ex-smokers showed a trend toward decreasing as the duration of abstinence became longer. CONCLUSION Among the three biomarkers, the plasma fibrinogen was the most strongly associated with the smoking status, its value being to be the highest in current smokers smoking ≥20 cigarettes daily. The same trend was also observed for the WBC count.

Abstract
BACKGROUND Despite animal evidence suggests that zinc modulates cadmium nephrotoxicity, limited human data are available. OBJECTIVE To test the hypothesis that low serum zinc concentrations may increase the risk of cadmium-mediated renal dysfunction in humans. METHODS Data from 1545 subjects aged 20 or older in the National Health and Nutrition Examination Survey (NHANES), 2011-2012 were analyzed. Renal function was defined as impaired when estimated glomerular filtration rate (eGFR) fell below 60 ml/min/1.73 m(2) and/or the urinary albumin-to-creatinine ratio surpassed 2.5 in men and 3.5mg/mmol in women. RESULTS Within the study cohort, 117 subjects had reduced eGFR and 214 had elevated urinary albumin. After adjusting for potential confounders, subjects with elevated blood cadmium (>0.53 μg/L) were more likely to have a reduced eGFR (odds ratio [OR]=2.21, 95% confidence interval [CI]: 1.09-4.50) and a higher urinary albumin (OR=2.04, 95% CI: 1.13-3.69) than their low cadmium (<0.18 μg/L) peers. In addition, for any given cadmium exposure, low serum zinc is associated with elevated risk of reduced eGFR (OR=3.38, 95% CI: 1.39-8.28). A similar increase in the odds ratio was observed between declining serum zinc and albuminuria but failed to reach statistical significance. Those with lower serum zinc/blood cadmium ratios were likewise at a greater risk of renal dysfunction (p<0.01). CONCLUSIONS This study results suggest that low serum zinc concentrations are associated with an increased risk of cadmium nephrotoxicity. Elevated cadmium exposure is global public health issue and the assessment of zinc nutritional status may be an important covariate in determining its effective renal toxicity.

Abstract
Background The pathomechanism and location of idiopathic sudden sensorineural hearing loss (ISSHL) is unclear. In a previous case-control study, we found elevated fibrinogen concentrations and a higher prevalence of T allele carriers of the glycoprotein (Gp) Ia C807T polymorphism in ISSHL patients. Methodology 127 patients with ISSHL (mean age 53.3 years, 48.8% females), who underwent a standard therapy with high dose steroids, pentoxifyllin and sterofundine over 8 days were included. We examined the influence of GpIa genotype and fibrinogen (BclI-, A312-, HaeIII-) genotype and fibrinogen plasma levels on hearing recovery after 8 weeks (change from baseline: 0 dB = no recovery, >0 to 10 dB = moderate recovery, >10 dB = good recovery). In a subsample of 59 patients with ISSHL, we further studied the association of platelet glycoprotein GpIa, Ib and IIIa densities on hearing recovery as well as the possible effect-modification of platelet glycoproteins on hearing recovery by plasma fibrinogen. Results In univariate analysis, neither the GpIa genotype nor fibrinogen genotype (all p>0.1) but lower fibrinogen levels (p = 0.029), less vertigo (p = 0.002) and lower GpIIIa receptor density (p = 0.037, n = 59) were associated with hearing recovery. In multivariate analysis, fibrinogen significantly modified the effect of GPIa receptor density on good hearing recovery (effect-modification on multiplicative scale OR = 0.45 (95% confidence interval (0.21–0.94)), p = 0.03). GPIb receptor density below the mean was associated with a 2-fold increase in good hearing recovery both in patients with fibrinogen levels above (p = 0.04) as well as in patients with fibrinogen levels below the mean (p = 0.06). There was no indication for an effect-modification (p = 0.97). Conclusions The findings suggest a vascular/rheological origin of ISSHL with unique features of thrombosis in the inner ear artery that may include complex interrelationships among platelet glycoproteins and plasma fibrinogen.

Abstract
Background Leukoaraiosis and cerebral microbleeds (CMB), which represent cerebral microangiopathy, commonly coexist in patients with acute lacunar stroke. Since they may have different impacts on stroke prognosis and treatment, it is important to know the factors associated with leukoaraiosis-predominant vs. CMB-predominant microangiopathies. Methods We prospectively recruited 226 patients with acute lacunar infarction and divided them into four groups according to the Fazekas’ score and the presence of CMB: mild, red (predominant CMB), white (predominant leukoaraiosis) and severe microangiopathy groups. For comparison, we also evaluated 50 patients with intracerebral hemorrhage (ICH). We evaluated the clinical and laboratory findings of microangiopathy subtypes in patients with acute lacunar stroke and then compared them with those of primary ICH. Results The risk factor profile was different among the groups. Patients with acute lacunar infarct but mild microangiopathy were younger, predominantly male, less hypertensive, and more frequently had smoking and heavy alcohol habits than other groups. The risk factor profile of red microangiopathy was similar to that of ICH but differed from that of white microangiopathy. The subjects in the white microangiopathy group were older and more frequently had diabetes than those in the red microangiopathy or ICH group. After adjustments for other factors, age [odds ratio (OR) 1.13; 95% confidence interval (CI) 1.08–1.18; p<0.001] and diabetes (OR 2.28; 95% CI 1.02–5.13; p = 0.045) were independently associated with white microangiopathy, and age (OR 1.05; 95% CI 1.01–1.08; p = 0.010) was independent predictor for red microangiopathy compared to mild microangiopathy. Conclusion Patients with acute lacunar infarction have a different risk factor profile depending on microangiopathic findings. Our results indicate that diabetes may be an one of determinants of white (leukoaraiosis-predominant) microangiopathy, whereas smoking and alcohol habits in relatively young people may be a determinants of mild microangiopahic changes in patients with lacunar infarction.

Abstract
PURPOSE Epidemiologic data suggest an association between cadmium exposure and cardiovascular disease though the underlying mechanisms remain unclear. This study explored the hypothesis that cadmium exposure is associated with elevated C-reactive protein (CRP) and fibrinogen, two risk factors for developing cardiovascular disease. METHODS The current study investigated associations between urinary cadmium and the prevalence of elevated blood CRP (> or = 2.2 mg/L) and fibrinogen (> or = 10.35 micromol/L) using data from a sample of 6497 participants aged 40-79 in the Third National Health and Nutrition Examination Survey. Logistic regression model was used to investigate existing associations while adjusting for confounding variables. RESULTS Both simple and covariate-adjusted models indicated that urinary cadmium was associated with elevated CRP and fibrinogen in a dose-dependent fashion (p(trend)<0.05 for both). Adjusted odds ratios for increased CRP and fibrinogen comparing highest with lowest quartiles of urinary cadmium were 1.62 (95% confidence interval [CI], 1.24-2.12) and 2.12 (1.43-3.14), respectively. CONCLUSIONS This analysis shows that cadmium exposure is associated with high prevalence of elevated CRP and fibrinogen. Additional study will be required to determine whether the increased risk derives from cadmium per se or from the environmental circumstances responsible for acquiring the contamination, e.g., cigarette smoking.

Abstract
UNLABELLED The role of plasma fibrinogen levels in predicting metabolic syndrome (MetS) and assessment of determinants of these levels were investigated. A total of 2234 men and women, aged 49+/-12 years, representative of Turkish adults who had plasma fibrinogen determinations, were prospectively evaluated and followed for a mean of 6.6 years. The modified Clauss method was used for assays. MetS was defined by ATPIII criteria modified for male abdominal obesity. MetS cases at baseline were excluded in prospective analyses. Median (interquartile range) fibrinogen values were 2.87 (2.29; 3.56) g/L. Fibrinogen levels predicted significantly newly developing MetS in men (RR 1.40 [95%CI 1.07; 1.83] for a 2-fold increment), after adjustment for age and smoking status, and (RR 1.32 [95%CI 0.95; 1.83] again for doubling), after additional adjustment for all 5 components of MetS. MetS was not significantly predicted by fibrinogen levels in women in either multivariable model. By regression analysis of eight covariates, not waist circumference, but systolic blood pressure, current smoking and C-reactive protein (CRP) in men, and age in women were predictors of elevated (>3.0 g/L) fibrinogen at follow-up (p<0.05 in all). CONCLUSIONS Plasma fibrinogen predicts MetS independently of its components in men, in contradistinction to women, and, hence, is likely one of its components. Hyperfibrinogenemia representing an inflammatory state is postulated as the underlying mechanism. Central obesity is linked to elevation in fibrinogen mainly through the mediation of blood pressure, CRP, and via being affected by cigarette smoking.

Abstract
The aim of this study was to evaluate the association between plasma FG levels and coexisting cardiovascular diseases (CVD) risk factors, comorbidities, functional status and cognitive function in a random sample of 270 (163 women and 107 men) community-dwelling elderly aged 65-79 years. The assessment included demographic and social variables, health status, nutritional state, physical and cognitive function. Physical activity was assessed by the Stanford Usual Activity Questionnaire. The average plasma FG level was lower in men 3.1+/-0.9 g/l (+/-SD) than in women 3.6+/-1.1g/l. In the whole group of elderly people, body mass index (BMI), percentage of body fat, calf circumference as well as total and low density cholesterol were positively correlated with FG levels, whereas the Stanford Moderate Index-negatively. Multifactor analysis of variance (ANOVA) revealed that female gender, calf circumference and the Stanford Moderate Index are the factors that independently predict FG levels. In conclusion, FG seems not to be related to functional status or cognitive function of older individuals. Nevertheless, our findings suggest that female gender, excess body fatness and low physical activity have an independent contribution to higher plasma FG levels in community-dwelling older subjects.

Abstract
Hemostatic processes are important in precipitating myocardial infarction and stroke. Elevated plasma fibrinogen is considered a risk factor for cardiovascular diseases (CVDs), but the results of previous studies on the association of plasma factor VIIc activity with CVD and diabetes have been inconsistent. The aim of the present study was to explore the association of plasma fibrinogen and factor VIIc to clinical characteristics and estimated coronary heart disease (CHD) risk in Aboriginal and Torres Strait Islander peoples. Cross-sectional surveys of Australian Aboriginal people (n = 852) and Torres Strait Islanders (n = 276) aged 15 years and older were conducted from 1993 to 1995. Anthropometric characteristics, blood pressure, fasting plasma fibrinogen, factor VIIc, total and high-density lipoprotein cholesterol, triglycerides, and glucose were measured. Levels of fibrinogen (mean, 95% confidence interval) for Aboriginal (3.52, 3.44-3.59 g/L) and Torres Strait Islander people (3.62, 3.49-3.75 g/L) were higher compared with previous reports from other populations. Factor VIIc (mean, 95% confidence interval) was especially high in Torres Strait Islanders (116%, 111%-122%) compared with Aboriginal people (99%, 97%-102%). Fibrinogen increased with age in both ethnic groups and sexes. Fibrinogen was independently associated with female sex, body mass index, renal dysfunction, low levels of high-density lipoprotein cholesterol and diabetes, whereas the independent predictors for factor VIIc were Torres Strait Islander ethnicity, female sex, body mass index, renal dysfunction, and total cholesterol. Average fibrinogen levels were high (>3.5 mg/dL) even for people considered "below average risk of coronary heart disease" according to conventional risk factor levels. For Aboriginal women, levels of fibrinogen and factor VIIc were significantly higher for persons at high risk than those at below average risk. The data suggest that plasma fibrinogen and factor VIIc might be important factors mediating the elevated CVD in Australian Indigenous Peoples. These data may have implications for prevention and treatment of CVD in Australian Indigenous communities.

Abstract
Family history of myocardial infarction (MI) is a known risk factor for coronary artery disease (CAD). The aim of the present study was to investigate whether there is a specific risk factor profile for CAD in individuals with a strong family history of MI occurring at any age. The Study of Health in Pomerania is a cross-sectional, population-based study in the north-east of Germany. A random sample was drawn from the population aged 20-79 years. From 3793 subjects with siblings, 34 (0.9%) reported a history of MI in at least one parent and one sibling. We matched these cases with 136 controls (1 : 4 matching for age, sex and presence of sibling). We then compared cases and controls with respect to known risk factors for MI. Subjects with a dual parental and sibling history of MI had higher plasma fibrinogen levels (3.5 versus 3.0 g/l, respectively), and also more often angina pectoris than the matched controls (P < 0.05). Multivariable analysis revealed an independent association between dual parental and sibling history of MI and plasma fibrinogen levels. We conclude that plasma fibrinogen levels may indicate an inheritable risk for CAD in subjects with a strong family history of MI.

Abstract
Beyond the already well-established strong causative relationship with cancer, smoking increases the risk for vascular disease. Smoking may act directly or adversely influence risk factors contributing to the development of vascular disease. Smoking causes endothelial dysfunction, dyslipidemia (decreased high-density lipoprotein cholesterol levels, hypertriglyceridemia and increased oxidation of low-density lipoprotein cholesterol) and platelet activation leading to a prothrombotic state. Smoking increases emerging risk factors (eg, fibrinogen, homocysteine, and high-sensitivity C-reactive protein) and increases insulin resistance and the risk of developing type 2 diabetes mellitus. The beneficial effects of statins and antioxidants (eg, vitamins C and E, beta-carotene) are counteracted by smoking. Smoking-induced alterations in growth factors, adhesion molecules, and even in genes can accelerate the progression of atherosclerosis. The aim of this review is to consider the adverse consequences of smoking on the factors predisposing to vascular disease and to emphasize the beneficial effects of smoking cessation.
