From Bench to Bedside in Precision Medicine: Diabetes Mellitus and Peri-Implantitis Clinical Indices with a Short-Term Follow-Up: A Systematic Review and Meta-Analysis. J Pers Med 2022; 12:jpm12020235. [PMID: 35207724 PMCID: PMC8878354 DOI: 10.3390/jpm12020235] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2021] [Revised: 01/31/2022] [Accepted: 02/05/2022] [Indexed: 02/04/2023] Open
Abstract
Background and objective: Diabetes mellitus (DM) refers to a group of metabolic disorders characterized by hyperglycemia resulting from impaired secretion or action of insulin. The high levels of glucose in the blood can negatively affect the healing processes through alterations in vascularization, bone remodeling, and with increased susceptibility to infections. Diabetes mellitus is therefore a risk factor not only for many systemic diseases, but also for localized problems such as peri-implantitis. The objective of this systematic review was to identify a clear relationship between peri-implant inflammation indices and glycemic levels, through the investigation of prospective studies that report data on a short-term follow-up period. Our hypothesis was that peri-implant inflammatory indices may already present themselves in a statistically significant way as altered in patients with DM compared to patients without DM. Materials and methods: This review was reported according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA). Results: More than 992 records were identified in the PubMed, Scopus, and Cochrane Central Register of Controlled Trial electronic databases and only seven studies were included in the meta-analysis. The results of the meta-analysis report worse outcomes in patients with DM, even in the short period of six months, for peri-implatitis inflammation indices, such as Marginal bone loss (standardized (Std). mean difference (MD) 12\6 months 0.81 [0.45, 1.17]\1.82 [0.53, 3.10]), Bleeding on probing (Std. MD 12\6 months 2.84 [1.34, 4.34]\3.44 [1.41, 5.50]), Probing depth (Std. MD 12\6 months 1.14 [0.60, 1.68]\2.24 [0.66, 3.83]), and the plaque index (Std. MD 12 months 2.83 [0.09, 5.57]). Conclusion: The literature linking glycaemic control to peri-implant disease is highly heterogeneous due to lack of consistency of the definition of peri-implantitis and its clinical indicators among studies. Therefore, interpretation of finding and relevance to clinical practice should be considered on individual bases. In the era of personalized medicine, the clinician should utilize individualized information from translational researches and analyze all risk factors to provide the patient with evidence-based treatment options.

Abstract
Carotid artery atherosclerosis is a major risk factor for both stroke and cardiovascular disease. Appropriate management of asymptomatic patients with carotid artery stenosis (CAS) remains unclear. Although several randomized clinical trials support revascularization in asymptomatic patients with severe CAS to reduce stroke risk, the participants in these trials did not receive optimal medical therapy (OMT) by today's standards. For many individuals, medical therapy may provide excellent risk reduction without the periprocedural risk of endarterectomy or stenting. In this review, we discuss the risk factors for CAS and stroke and examine the data for each component of OMT in these patients.

Abstract
Introduction Intimal media thickness (IMT) of common carotid artery (CCA) is used as an index of atherosclerosis. IMT is increased in subjects with diabetes and also with diabetic nephropathy. Aim The study was undertaken in South Indian type 2 diabetic patients with different degrees of albuminuria to see whether albuminuria worsened IMT. Material and methods IMT was measured by ultrasonography in 273 diabetic subjects with normoalbuminuria (n=91), microalbuminuria (n=92), clinical proteinuria (Prot) (n=90) and in age-matched non-diabetic subjects (n=99). The diabetic subjects were older than the non-diabetic subjects hence IMT was age-adjusted using a linear regression formula. Results Age-adjusted IMT value in diabetic subjects was significantly higher (0.88±0.3 mm) than in non-diabetic subjects (0.57±0.34 mm) (p<0.001). Mean IMT in normoalbuminuria (0.87±0.26 mm), microalbuminuria (0.90± 0.33 mm) and Prot (0.86±0.39 mm) patients were not significantly different from each other. Male gender, age, diabetes and total cholesterol were independently associated with IMT, while duration of diabetes, hypertension and HbA1C were not. Conclusion Increased carotid IMT occurred in type 2 diabetes prior to the presence of albuminuria. Further deterioration in IMT did not occur with the presence of albuminuria.

Abstract
AIM Carotid atherosclerosis progression is associated with a higher risk of cerebrovascular events but there is no specific data for diabetes. We assessed in a cohort of patients with diabetes the rate of atherosclerosis progression by Doppler ultrasonography and the association with cerebrovascular events. METHODS We analyzed a retrospective cohort of 342 patients with a mean duration of diabetes of 13.6 ± 10.6 years. The mean delay between the first and last Doppler ultrasonography was 6.4 ± 4.6 years, with a mean of 3.4 examinations per person. Cerebrovascular events were noted. RESULTS A progression of carotid atherosclerosis was observed in 20.1% of cases. No factor was significantly associated with progression. A prophylactic carotid endarterectomy was performed on 6 of the 27 patients with a stenosis ≥50%. A cerebrovascular event occurred in 1.2% of patients; none of them had carotid atherosclerosis progression. CONCLUSIONS Carotid atherosclerosis progression in patients with diabetes is frequent but surgical treatment and cerebrovascular events are low. The benefit of a systematic follow-up of carotid atherosclerosis seems limited.

Abstract
The present review focuses on the roles of thromboxane A2 (TxA2) in arterial thrombosis, atherogenesis, vascular stent-related ischemic events and renal proteinuria. Particular emphasis is laid on therapeutic interventions targeting the TxA2 (TP) receptors and TxA2 synthase (TS), including dual TP-receptor antagonists and TS inhibitors. Their significant inhibitory efficacies on arterial thrombogenesis, atherogenesis, restenosis after stent placement, vasoconstriction and proteinuria indicate novel and improved treatments for cardiovascular and selected renal diseases. New therapeutic interventions of the TxA2 pathway may also be beneficial for patients with poor biological antiplatelet drug response, for example, to aspirin and/or clopidogrel. These new TP/TS agents offer novel improved treatments to efficiently and simultaneously interfere with thrombogenesis and atherogenesis, and to enlarge the existing panel of platelet inhibitors for efficient prophylaxis and treatment of arterial thrombosis and renal proteinuria.

Abstract
AIM To investigate the impact of a history of diabetes mellitus on the neurologic outcome in comatose survivors of cardiac arrest of cardiac origin treated with mild hypothermia. METHODS A prospective observational study was performed between September 2003 and July 2008. Eighty comatose survivors of cardiac arrest of cardiac origin were treated with mild hypothermia. Neurologic outcome at the time of hospital discharge, 30-day survival, and complications were assessed. RESULTS Twenty-four of the 80 patients (30%) had a history of diabetes. The rate of favorable neurologic outcome was significantly lower in diabetic (17%) than in nondiabetic patients (46%) (p=0.01). The rate of 30-day survival was lower in diabetic (33%) than in nondiabetic patients (54%), but the difference was not significant (p=0.10). Multivariate analysis suggested that a history of diabetes was an independent predictor of unfavorable neurologic outcome (odds ratio 7.00, 95% confidence interval 1.42-46.19, p=0.03), but not for 30-day survival. There was no significant difference in the prevalence of complications. CONCLUSION A history of diabetes is associated with poor neurologic outcome in comatose survivors of cardiac arrest treated with mild hypothermia.

Abstract
BACKGROUND AND PURPOSE In the discussion on the value of population-wide screening for asymptomatic carotid artery stenosis (ACAS), reliable prevalence estimates are crucial. We set out to provide reliable age- and sex-specific prevalence estimates of ACAS through a systematic literature review and meta-regression analysis. METHODS We searched PubMed and EmBase until December 2007 for studies that reported the prevalence of ACAS in a population free of symptomatic carotid artery disease. Data were extracted with use of a standardized form on participants' characteristics, assessment method, study quality, and prevalence estimates for moderate (>or=50% stenosis) and severe (>or=70% stenosis) ACAS. Metaregression was used to investigate sources of heterogeneity. RESULTS Forty studies fulfilled the inclusion criteria. There was considerable variation among studies with respect to demographics, methods of grading stenosis, and stenosis cutoff point used. The pooled prevalence of moderate stenosis was 4.2% (95% CI, 3.1% to 5.7%). Prevalence of moderate stenosis among people age <70 years was 4.8% (95% CI, 3.1% to 7.3%) in men and 2.2% (95% CI, 0.9% to 4.9%) in women. Among those >or=70 years, prevalence increased to 12.5% (95% CI, 7.4% to 20.3%) in men and to 6.9% (95% CI, 4.0% to 11.5%) in women. Metaregression showed that both age and sex significantly affected the prevalence of moderate stenosis. No contribution of study size, publication year, geographic region, assessment method, and study quality was found. The pooled prevalence of severe stenosis was 1.7% (95% CI, 0.7% to 3.9%). CONCLUSIONS Prevalence of moderate stenosis increases with age in both men and women, but men at all ages have the higher prevalence estimates. The number of studies that allowed meaningful data synthesis of severe stenosis was limited.

Abstract
Diabetes is associated with a high incidence and poor prognosis of cardiovascular disease, and with high short- and long-term mortality. Adequate treatment of cardiovascular disorders and aggressive management of coexisting risk factors have proved to be at least as effective in diabetic as in nondiabetic patients in randomized, controlled studies. Indeed, treating diabetic patients with cardiovascular disease results in a larger absolute risk reduction than in nondiabetic subjects. Nevertheless, diabetic patients often receive inadequate therapy, which may, to a certain extent, explain their poor prognosis. Recommendations for the treatment of diabetic patients with acute myocardial infarction should include beta-blockers, aspirin, and ACE-inhibitors in all patients in whom no specific contraindications exist. Fibrinolysis should be administered when indicated, and the benefits of improving glycemic control should not be forgotten either. In patients with multi-vessel disease who need revascularization, when selecting the type of procedure, the superiority of surgical revascularization over angioplasty should be borne in mind. Even heart transplantation should be included as a therapeutic option since there are no data to support the exclusion of patients on account of their diabetes. Finally, coexisting risk factors should be intensively treated through lifestyle intervention, with or without drug therapy, in order to achieve secondary prevention goals.

Abstract
BACKGROUND AND PURPOSE This study was designed to evaluate cerebral hemodynamic changes related to diabetes mellitus (DM) with transcranial Doppler ultrasonography (TCD). METHODS We measured the flow velocities and the Gosling pulsatility index (PI) of the middle cerebral artery (MCA), extracranial internal carotid artery (ICA), and basilar artery (BA) in 56 stroke-free, normotensive patients with type 2 DM and 70 age- and gender-matched healthy volunteers. Patients were divided into 2 groups according to the presence of microvascular complications such as retinopathy, nephropathy, and neuropathy. RESULTS Patients showed slightly lower hematocrit and higher serum fibrinogen levels than control subjects, but other clinical profiles, including stroke risk factors except for diabetes, were comparable between patients and controls. The flow velocity of the ICA but not the MCA and BA in patients regardless of the complication was significantly higher than that in controls. The PIs of the MCA and ICA were significantly higher in patients with complication than those without complication, as well as in controls. The PI of the BA was also significantly higher, even in patients without complication, than in controls. The PIs of the MCA and ICA but not the BA were closely correlated with the duration of DM (r(2)=0.46 and 0.34, respectively). CONCLUSIONS This study defines TCD findings of diabetes-related cerebral hemodynamic changes and suggests that the PI reflects microangiopathic changes of cerebral vessels.

Abstract
The purpose of this study was to examine the associations of carotid artery intima-media wall thickness (IMT) with hemostatic proteins and cardiovascular risk factors (CVRFs) in participants with and without non-insulin dependent diabetes mellitus (NIDDM). IMT measurements were determined by high resolution B-mode ultrasound imaging of the carotid arteries in 921 participants with NIDDM and 11,964 non-diabetic participants aged 45-64 years. Fasting glucose, serum lipids and activated partial thromboplastin time, factor VIII fibrinogen, factor VII, antithrombin III, protein C, and von Willebrand factor measurements were made. Compared to non-diabetic participants, participants with NIDDM had a more adverse pattern of CVRFs and a more procoagulatory profile. Participants with NIDDM had 0.06 mm (8.1%) higher mean IMT compared to non-diabetic participants after adjusting for age and gender (P < 0.001). However, only plasma fibrinogen concentrations showed statistically significant positive associations with IMT in both groups. After adjusting for CVRFs and fibrinogen, mean IMT remained 0.04 mm (5.4%) higher in diabetic compared to non-diabetic participants. Despite the more procoagulatory profile in participants with NIDDM, only plasma fibrinogen concentrations were independently associated with mean IMT. The association of NIDDM with mean IMT was only partly explained by CVRFs.

Abstract
Intrarenal hemodynamics were studied by duplex Doppler sonography in 112 inpatients with type II diabetes mellitus (DM; 65 males, 47 females, 58 +/- 13 years old). The resistive index (RI) and pulsatility index (PI) of the interlobar arteries were calculated. The patients were divided into four groups: group I consisted of patients with urinary albumin excretion (UAE) < 20 micrograms/min (N = 42), group II with 20 < or = UAE < 200 (N = 28), group III with UAE > or = 200 (N = 25), and group IV with serum creatinine > or = 1.5 mg/dl (N = 17). Both RI and PI values in groups II, III, and IV were significantly higher than those in the controls (age- and sex-matched healthy persons, N = 37; P < 0.001), and those in group IV were significantly higher than those in groups I, II, and III (P < 0.0001). Multiple regression analysis revealed that RI values in DM patients were significantly affected by creatinine clearance, age, and duration of diabetes (R2 = 0.554, P < 0.0001). When intima-medial thickness (IMT) of the femoral and carotid arteries were measured by B-mode ultrasonography, RI values were significantly correlated with both the femoral and carotid arterial IMT. These results demonstrate that intrarenal hemodynamic abnormalities are present in type II DM patients with nephropathy, and that intrarenal hemodynamics are affected by decreased glomerular function and also probably by advanced arteriosclerosis.

Diabetes mellitus is a risk factor for ischemic, but not hemorrhagic stroke. The frequency of transient ischemic attacks is not increased in patients with diabetes compared to the general population. Diabetes mellitus is associated with higher mortality, worse functional outcome, more severe disability after stroke and a higher frequency of recurrent stroke. Diabetes is not associated with an increased size of cerebral infarction. Controversy exists regarding whether hyperglycemia adversely affects stroke outcome or primarily reflects stroke severity. Cerebral blood flow disturbances, impaired cerebrovascular reactivity, and damage to large and small extra- and intracranial cerebral vessels have been found in humans and animals with diabetes. Combinations of some or all of these factors may underlie the high incidence and worse outcome of stroke in patients with diabetes. Knowledge of these pathophysiologic factors will assist in the design of future intervention strategies.

Abstract
BACKGROUND AND PURPOSE We assessed the effects of long-term treatment with picotamide, an antiplatelet agent with dual antithromboxane activity, on the evolution of early asymptomatic carotid atherosclerotic lesions in diabetic patients. METHODS In a double-blind, placebo-controlled, 2-year study, 50 type II normotensive diabetic patients (35 men; mean age, 66 +/- 5 years) with asymptomatic mild or moderate nonstenotic (< 50%) carotid atherosclerotic lesions and negative history of cerebrovascular ischemic events were enrolled and randomly given picotamide (300 mg TID) or the corresponding placebo. A high-resolution, real-time B-scan echographic assessment of carotid arteries was performed at baseline and after 1, 3, 6, 12, 18, and 24 months of double-blind treatment. Prevalence and evolutionary trends of carotid atherosclerotic lesions (number per patient and mean stenosis expressed as percent) were considered as efficacy primary end points. RESULTS At baseline, mean +/- SD numbers of carotid atherosclerotic lesions per patient were 2.7 +/- 1.8 and 2.2 +/- 1.2 in the picotamide and placebo groups, respectively. Mean +/- SD percent stenosis was 25.3 +/- 7% in the picotamide group and 27.3 +/- 6% in the placebo group. Forty-nine patients completed the study. At month 24, the placebo group (n = 24) showed a significant progression in number of carotid atherosclerotic lesions (3.04 +/- 1.8; P < .02 versus baseline) and in mean percent stenosis (35 +/- 17%; 95% confidence interval, 33% to 37%; P < .01 versus baseline). In the picotamide group (n = 25), mean number of carotid atherosclerotic lesions (2.7 +/- 1.6) and percent stenosis (26 +/- 9%; 95% confidence interval, 24.8% to 27.2%) remained unchanged. At month 24, compared with randomized placebo, lesion numbers (P < .03) and percent stenosis (P < .01) in the picotamide group were significantly lower. During the study, 12 patients experienced major or minor ischemic vascular events (9 in the placebo group and 3 in the picotamide group; P = .07). CONCLUSIONS In diabetic patients compared with patients receiving placebo, long-term treatment with picotamide can slow the evolution of early carotid atherosclerotic lesions, inhibiting progression of plaque number and growth.

Abstract
We studied the MRI appearances of the brain in 159 patients with diabetes mellitus (DM) and 2566 age-matched individuals without DM (controls). The images were reviewed for cerebral infarcts, hemorrhage, atrophy and subcortical arteriosclerotic encephalopathy. Cerebral atrophy was significantly more frequent in patients with DM than in controls (P > 0.005) from the sixth to the eighth decade. The frequency of atrophy was 41.2% in the 6th decade, 60.0% in the 7th and 92.3% in the 8th decade in DM, and 19.8%, 38.9% and 56.8% respectively in controls. Unexpectedly, there was no statistically significant difference in the incidences of cerebrovascular diseases at any age.

Abstract
BACKGROUND AND PURPOSE Little information is available on extracranial carotid artery disease in free-living elderly individuals. We sought to evaluate the prevalence of carotid lesions in the elderly. METHODS Using echo-Doppler, we assessed the prevalence of possible atherosclerotic lesions in the internal carotid arteries (n = 478) and the external and common carotid arteries (n = 956) of 239 subjects 65-94 years of age living in retirement homes in Seattle, Wash. RESULTS We found that 152 (31.8%) internal carotid arteries were affected by nonstenosing plaque and 37 arteries (7.7%) had stenosis or occlusion. In addition, 193 (20.2%) external or common carotid arteries showed nonstenosing plaques. There were 128 subjects (53.6%) with internal carotid disease, 106 (44.3%) with evidence of external or common carotid disease, and 75 (31.4%) affected by disease in all three sites. There were 80 subjects (33.5%) with no ultrasound evidence of carotid disease. We found that the presence and severity of carotid disease increased between the decades 65-74 and 75-84. We also demonstrated a positive association between systolic blood pressure and ultrasound evidence of carotid disease that was independent of age. CONCLUSIONS The prevalence of extracranial artery disease in an apparently healthy population was high, although stenoses in most instances were not severe. We conclude that noninvasive ultrasound methods identify a relatively small fraction of individuals (5% of the total) at high risk for stroke or transient ischemic attack. Echo-Doppler might be used to monitor further disease progression and to evaluate the efficacy of different therapeutic or preventive interventions.

Abstract
The prevalence of glucose intolerance and diabetic complications was determined in second-generation Japanese-American (Nisei) women and compared to previously obtained results in Nisei men. A volunteer study sample of 191 Nisei women 45-74 years old was enrolled from a study population of 1489 Nisei women born 1913-1942, raised and educated in the U.S., and residing in King County, Washington. The enrolled sample included 72 with normal glucose tolerance, 67 with impaired glucose tolerance (IGT), and 52 with non-insulin-dependent diabetes. A random sample was also drawn from the study population to form a reference sample of 157 women. Based upon observations in the reference and enrolled samples, an estimated 16% of Nisei women in the study population have diabetes and 40% IGT. These rates compare to 20% diabetes and 36% IGT previously estimated for Nisei men 45-74 years old. The prevalence of cardiovascular disease (hypertension, peripheral vascular disease, and/or coronary heart disease) was highest among diabetic women, lowest in those with normal glucose tolerance, and intermediate in women with IGT. In comparison to diabetic men, there was a significantly lower frequency of neuropathy, peripheral vascular disease, and coronary heart disease in diabetic women. However, hypertension occurred equally often in both. Thus Japanese-American men and women 45-74 yr old have a similar prevalence of glucose intolerance, although less severe in women, and complications, except for hypertension, are reduced in women.

Abstract
The degree of arterial stenosis in both the right and left extracranial (common and internal) carotid arteries (ECAS) was assessed in 118 elderly (65 years and older; male 66) stroke patients by a Duplex Pulsed Wave ultrasound system (ATL 500). Of these, 33 (28%) had severe stenosis (75-100%), 16 (14%) had moderate stenosis (30-74%) and 69 (58%) had no or minimal stenosis (0-29%). Overall, 34% (n = 40) of strokes were associated with moderate or severe stenosis in the ipsilateral extracranial carotid artery. Multivariate logistical regression analysis showed a significant (P less than 0.05) positive correlation between ECAS (as assessed in either artery) and ischaemic heart disease, systolic blood pressure and male sex (multiple correlation coefficient, r = 0.240). The results were similar when the analysis was repeated for ECAS in the 'clinically significant' (maximal stenosis ipsilateral to the stroke) arteries only (multiple correlation coefficient, r = 0.276). The relationships, however, were weak, suggesting that other factors not identified in this study are more important aetiological factors for extracranial carotid artery atherosclerosis in the elderly.

Abstract
We noninvasively evaluated the prevalence and severity of atherosclerotic lesions of the internal carotid artery in 146 nonobese, nondiabetic hypertensive patients who were free of cardiovascular symptoms. We found internal carotid artery disease in 63 patients (43%), 26 (18%) with unilateral disease and the other 37 (25%) with bilateral disease. Disease severity was correlated with age but not duration of hypertension, cholesterol level, or current smoking habit. We also followed disease progression and clinical outcome with respect to cardiovascular events for 3 years in a subgroup of 95 unselected patients. In 20 of the 93 survivors (21.5%) we noted progression of the atherosclerotic lesions that was predicted by neither risk factors nor initial status of the internal carotid artery. New neurologic symptoms developed in four survivors (4%) and symptoms of cardiac ischemia in six (6%). No survivor who developed new cerebrovascular symptoms showed progression of carotid disease. These data provide useful elements for a rational approach to prevention of the atherosclerotic complications of hypertension.

Abstract
Non-insulin-dependent diabetes mellitus is predominantly a disease of aging, with more than 70 percent of non-insulin-dependent (type II) diabetic patients older than 55 years of age. The prevalence of macrovascular, microvascular, and neurologic complications in outpatients with type II diabetes between the ages of 55 and 74 was compared with that in a similarly aged nondiabetic group of patients. The association between duration of diabetes, hypertension, age, and other putative risk factors that are prevalent in this elderly diabetic population and the occurrence of complications was explored. This cross-sectional survey confirmed a significant increase in retinopathy, neuropathy, impotence, and macrovascular complications in patients with type II diabetes. Within the diabetic population, duration of disease was associated with the occurrence of retinopathy and neuropathy, but not associated with such macrovascular complications as coronary artery disease. Gender, type of therapy, and previously identified risk factors for vascular disease such as hypertension had little impact on the prevalence of complications in this population. The notion that type II diabetes in the elderly represents "mild" diabetes with regard to complications must be discarded. Further identification of risk factors within this diabetic population may suggest therapeutic approaches that will prevent or ameliorate the development of complications.

Abstract
Diabetic patients suffer from atherosclerotic diseases more often and at an earlier stage than nondiabetic persons. The factors predisposing those with diabetes to premature arteriosclerosis are not fully clarified. Data from a 5-year follow-up of 615 diabetic outpatients of the Schwabing Study are reported. Forty-six (8.5%) died from a cardiovascular cause of death, 13 (2.4%) suffered from stroke, 68 (12.5%) showed electrocardiographic changes indicative of significant coronary heart disease, and 11 (2.0%) exhibited an ischemic foot lesion. Univariate and multiple logistic analyses of baseline variables revealed systolic blood pressure as the most consistent risk factor for these events. The frequency of major cardiovascular events was as high in men as in women. It is concluded that systolic blood pressure has been seriously underestimated as a predictor for macrovascular events.
