Depression and anxiety symptoms are underestimated risk factors for postoperative prognosis in patients with Type 2 diabetes and peripheral artery disease undergoing partial foot amputation: Results from a prospective cohort study.

OBJECTIVE: The aim of this study was to evaluate the prevalence and impact of depression and anxiety symptoms on post-operative prognosis and 1-year all-cause mortality in a large unique cohort of patients with Type 2 diabetes (T2D) and peripheral artery disease (PAD) after partial foot amputation (PFA). METHODS: Prospective cohort study with 1-year follow-up of 785 consecutive patients (mean age 60.9 ± 9.1 years; 64.1% males) with T2D and PAD after PFA. Depressive symptoms were assessed by Patient Health Questionnaire-9 (PHQ-9) and anxiety symptoms by Hamilton Anxiety Rating Scale (HARS). We used multivariable Cox proportional hazard models to examine the association of depression and anxiety with all-cause mortality. RESULTS: One-year all-cause mortality was 16.9% (n = 133). 331 (42.1%) patients had PHQ-9 score ≥ 10 indicating major depressive disorder. After adjusting for confounders, PHQ-9 score ≥ 10 was associated with an increased risk of 1-year all-cause mortality (HR = 1.68 (95%CI[1.16-2.44], p = 0.006). Depression dimensions of negative self-feeling and suicidal ideations were independently associated with 1-year mortality (HR = 1.26 (95%CI[1.24-1.55], p = 0.029 and HR = 2.37 (95%CI[1.89-2.96], p < 0.001, respectively). Compared to no depression, severe depressive symptoms (cut-off≥20) were associated with increased all-cause mortality (HR = 3.9 (95%CI [1.48-10.29], p = 0.006). Compared to no anxiety, severe anxiety symptoms (cut-off>30) were associated with increased 1-year mortality (HR = 2.25(95%CI [1.26-4.05], p = 0.006). CONCLUSION: Depressive symptoms and severe anxiety have shown independently increased risk of 1-year all-cause mortality in patients with T2D and PAD requiring PFA. Our results indicate that screening for anxiety and depression should be considered under these circumstances to identify patients at increased risk to allow appropriate intervention.

Impact of Persistent Medication Adherence and Compliance with Lifestyle Recommendations on Major Cardiovascular Events and One-Year Mortality in Patients with Type 2 Diabetes and Advanced Stages of Atherosclerosis: Results From a Prospective Cohort Study.

Background: The aim of this study was to evaluate the impact of single and combined effects of persistent medication adherence and compliance with lifestyle recommendations on the incidence of major adverse cardiovascular events (MACE) and one-year all-cause mortality in patients with type 2 diabetes (T2D) and peripheral artery disease (PAD) after partial foot amputation (PFA), representing a unique cohort of patients with advanced stages of atherosclerosis. Methods: This is a prospective cohort study of 785 consecutive patients (mean age 60.9 ± 9.1 years; 64.1% males). Medication adherence was evaluated by using the proportion of days covered (PDC) measure calculation and was defined as a PDC ≥80%. It derived as an average of PDCs of the following four classes of drugs: a) antidiabetics (oral hypoglycemic medications and/or insulin); b) ACEI or ARBs; c) Statins; d) antiplatelet drugs. Lifestyle compliance was defined as a PDC ≥80% comprising of PDCs of a) physical activity of ≥30 minutes per day; b) healthy nutrition and weight management; c) non-smoking. Cox proportional hazard models adjusted for confounders were used. Results: Total all-cause mortality was 16.9% (n = 133) at one-year follow-up. After adjusting for confounders, compared to adherent/compliant patients (n = 432), non-adherent and/or non-compliant patients had an increased risk of one-year mortality: HR = 8.67 (95% CI [5.29, 14.86] in non-adherent/non-compliant patients (n = 184), p < 0.001; HR = 3.81 (95% CI [2.03, 7.12], p < 0.001) in adherent/non-compliant patients (n = 101) and HR = 3.14 (95% CI [1.52, 6.45] p = 0.002) in non-adherent/compliant patients (n = 184). The incidence of MACE followed similar pattern (HR = 9.66 (95% CI [6.55, 14.25] for non-adherence/non-compliance; HR = 3.48 (95% CI [2.09, 5.77] and HR = 3.35 (95% CI [1.89, 5.91], p < 0.001 for single adherence or compliance. Conclusions: Medication adherence and compliance to lifestyle recommendations have shown to be equally effective to reduce the incidence of MACE and one-year mortality in patients with diabetes and PAD after PFA representing a population with highly advanced stages of atherosclerotic disease. Our findings underline the necessity to give lifestyle intervention programs a high priority and that costs for secondary prevention medications should be covered for patients under these circumstances. Lay Summary: This study analyzed the single and combined effects of medication adherence and compliance with lifestyle recommendations on cardiovascular events and mortality in patients with type 2 diabetes and advances stages of atherosclerosis over a period of one year.Evaluation of medication adherence included antidiabetics, statins, dual antiplatelets and ACEI/ARBs, whereas lifestyle recommendations included healthy nutrition, physical activity and smoking cessation.Persistent medication adherence and lifestyle changes have shown to be equally effective to reduce the incidence of MACE and one-year mortality in patients representing a population with highly advanced stages of atherosclerotic disease, and positive effects added up to a double effect if patients were persistently adherent and compliant with both interventions.

What is resistant arterial hypertension?

PURPOSE: The current review is to describe the definition and prevalence of resistant arterial hypertension (RAH), the difference between refractory hypertension, patient characteristics and major risk factors for RAH, how RAH is diagnosed, prognosis and outcomes for patients. MATERIALS AND METHODS: According to the WHO, approximately 1.28 billion adults aged 30-79 worldwide have arterial hypertension, and over 80% of them do not have blood pressure (BP) under control. RAH is defined as above-goal elevated BP despite the concurrent use of 3 or more classes of antihypertensive drugs, commonly including a long-acting calcium channel blocker, an inhibitor of the renin-angiotensin system (angiotensin-converting enzyme inhibitor or angiotensin receptor blocker), and a thiazide diuretic administered at maximum or maximally tolerated doses and at appropriate dosing frequency. RAH occurs in nearly 1 of 6 hypertensive patients. It often remains unrecognised mainly because patients are not prescribed ≥3 drugs at maximal doses despite uncontrolled BP. CONCLUSION: RAH distinctly increases the risk of developing coronary artery disease, heart failure, stroke and chronic kidney disease and confers higher rates of major adverse cardiovascular events as well as increased all-cause mortality. Timely diagnosis and treatment of RAH may mitigate the associated risks and improve short and long-term prognosis.

Resistant arterial hypertension is a serious condition that leads to severe cardiovascular complications, such as heart attack, stroke and death.It is defined as above-goal elevated blood pressure despite the concurrent use of 3 or more classes of antihypertensive medications administered at maximum or maximally tolerated doses and at appropriate dosing frequency.Non-adherence to antihypertensive medications must be excluded before resistant arterial hypertension is diagnosed.Blood pressure should be measured appropriately. A person should sit in a comfortable chair with back supported, both feet flat on the ground, and legs uncrossed for at least 5 min before blood pressure measurement. A cuff length is supposed to be at least 80% and a width of at least 40% of the arm circumference. Placing the cuff directly on the skin of the upper arm at the level of the heart. Obtaining 3 readings 1 min apart. Discarding the first reading and taking the mean of the second and third readingsResistant arterial hypertension should be distinguished from refractory hypertension, when blood pressure remains uncontrolled on maximal or near-maximal therapy of 5 or more antihypertensive agents of different classes.

Coronary artery calcium score and coronary computed tomography angiography predict one-year mortality in patients with type 2 diabetes and peripheral artery disease undergoing partial foot amputation.

METHODS: This is a single-center prospective cohort study including 199 consecutive patients with T2D, PAD (mean age 62.3 ± 7.2 years; 62.8% males), and preoperative CACS and CCTA undergoing PFA and followed-up over 1 year. RESULTS: Over a period of 1 year follow-up, a total of 35 (17.6%) participants died. The area under ROC curve to predict mortality for the CACS was 0.835 (95% CI:0.769-0.900), for CCTA 0.858 (95% CI:0.788-0.927). After adjustment for confounders, compared to no-stenosis on CCTA (reference), the risk of all-cause mortality in non-obstructive coronary atery disease (CAD) increased (HR = 1.38, 95% CI [0.75-12.86], p = .284), 1-vessel obstructive CAD (HR = 8.13, 95% CI [0.87-75.88], p = .066), 2-vessels (HR = 10.94, 95% CI [1.03-115.8], p = .047), and 3-vessels (HR = 45.73, 95% CI [4.6-454.7], p = .001) respectively. Increasing levels of CACS tended to be associated with increased risk of all-cause mortality (HR = 1.002, 95% CI [1.0-1.003], p = .061). 61/95 patients with obstructive CAD underwent coronary revascularization. CONCLUSIONS: Coronary artery calcium score and CCTA have a high predictive value for 1-year all-cause mortality in T2D patients undergoing minor amputations and may be considered for preoperative risk assessment allowing timely preventive interventions.

Renal denervation in the antihypertensive arsenal - knowns and known unknowns.

Even though it has been more than a decade since renal denervation (RDN) was first used to treat hypertension and an intense effort on researching this therapy has been made, it is still not clear how RDN fits into the antihypertensive arsenal. There is no question that RDN lowers blood pressure (BP), it does so to an extent at best corresponding to one antihypertensive drug. The procedure has an excellent safety record. However, it remains clinically impossible to predict whose BP responds to RDN and whose does not. Long-term efficacy data on BP reduction are still unconvincing despite the recent results in the SPYRAL HTN-ON MED trial; experimental studies indicate that reinnervation is occurring after RDN. Although BP is an acceptable surrogate endpoint, there is complete lack of outcome data with RDN. Clear indications for RDN are lacking although patients with resistant hypertension, those with documented increase in activity of the sympathetic system and perhaps those who desire to take fewest medication may be considered.

Opportunities and challenges of using social media big data to assess mental health consequences of the COVID-19 crisis and future major events.

The present commentary discusses how social media big data could be used in mental health research to assess the impact of major global crises such as the COVID-19 pandemic. We first provide a brief overview of the COVID-19 situation and the challenges associated with the assessment of its global impact on mental health using conventional methods. We then propose social media big data as a possible unconventional data source, provide illustrative examples of previous studies, and discuss the advantages and challenges associated with their use for mental health research. We conclude that social media big data represent a valuable resource for mental health research, however, several methodological limitations and ethical concerns need to be addressed to ensure safe use.

Is Lone Hypertension a Risk Factor for More Severe COVID-19 Outcomes?

Background: Based on current evidence, it is not clear whether lone hypertension increases the risk for severe illness from COVID-19, or if increased risk is mainly associated with age, obesity and diabetes. The objective of the study was to evaluate whether lone hypertension is associated with increase mortality or a more severe course of COVID-19, and if treatment and control of hypertension mitigates this risk. Methods: This is a prospective multi-center observational cohort study with 30-day outcomes of 9,531 consecutive SARS-CoV-2 PCR-positive patients ≥ 18 years old (41.9 ± 9.7 years, 49.2% male), Uzbekistan, June 1-September 30, 2020. Patients were subclassified according to JNC8 criteria into six blood pressure stages. Univariable and multiple logistic regression was conducted to examine how variables predict outcomes. Results: The 30-days all-cause mortality was 1.18% (n = 112) in the whole cohort. After adjusting for age, sex, history of myocardial infarction (MI), type-2 diabetes, and obesity, none of six JNC8 groups showed any significant difference in all-cause mortality. However, age was associated with an increased risk of 30-days all-cause mortality (OR = 1.09, 95%CI [1.07-1.12], p < 0.001), obesity (OR = 7.18, 95% CI [4.18-12.44], p < 0.001), diabetes (OR 4.18, 95% CI [2.58-6.76], p < 0.001), and history of MI (OR = 2.68, 95% CI [1.67-4.31], p < 0.001). In the sensitivity test, being ≥ 65 years old increased mortality 10.56-fold (95% CI [5.89-18.92], p < 0.001). Hospital admission was 12.4% (n = 1,183), ICU admission 1.38% (n = 132). The odds of hospitalization increased having stage-2 untreated hypertension (OR = 4.51, 95%CI [3.21-6.32], p < 0.001), stage-1 untreated hypertension (OR = 1.97, 95%CI [1.52-2.56], p < 0.001), and elevated blood pressure (OR = 1.82, 95% CI [1.42-2.34], p < 0.001). Neither stage-1 nor stage-2 treated hypertension patients were at statistically significant increased risk for hospitalization after adjusting for confounders. Presenting with stage-2 untreated hypertension increased the odds of ICU admission (OR = 3.05, 95 %CI [1.57-5.93], p = 0.001). Conclusions: Lone hypertension did not increase COVID-19 mortality or in treated patients risk of hospitalization.

The new differential diagnostic test for the lichenoid drug eruption.

The differential diagnosis between lichenoid drug eruption (LDE) and lichen planus (LP) is difficult due to similar clinical and histological signs but important for treatment and prognosis. The purpose of this study was to propose the new diagnosis method for differentiate LDE from LP. During 2015-2018, 20 patients with confirmed LDE, 13 patients with LP and 134 controls were examined and treated at the Lenoblcenter. All enrolled patients were underwent the injection of 0.5 mL of the 2% lidocaine solution by insulin syringe into the papule with following histological examination. The formation of a blister (bulla) at the site of injection was considered a positive test result. Among LDE, 18 of 20 patients were found positive for developing blister (bulla) and two results were questionable. In 12 of 13 LP patents, bulla on the site of injection was not identified and the result of one patient was nonspecific. All control patients were negative for the proposed test. The histological sections showed that the bulla has corresponded to the separation of the epidermis from the dermis. Intracutaneous injection of 0.5 mL of lidocaine into the papule is an easy highly specific and sensitive method to differentiate LDE from LP.

Tenfold risk increase of major cardiovascular events after high limb amputation with non-compliance for secondary prevention measures.

Background The aim of the study was to evaluate the impact of compliance with lifestyle recommendations and medication on 1-year prevention of major adverse cardiovascular events (MACE) in patients with type 2 diabetes (T2D) after trans-femoral amputation (TFA). Methods In this prospective single-center interventional cohort study, 179 consecutive T2D patients with symptomatic coronary artery disease (CAD) underwent 1-year follow-up examination after TFA in 2013. Lower limb and coronary artery CT angiography were provided before surgery; physical examination and laboratory tests were performed at baseline and every month after TFA for 1 year. A total of 77 patients (43%) were defined as compliant. They followed all recommendations, including >80% drug intake (anti-diabetic, antihypertensive drugs, dual antiplatelet and statin treatment), healthy diet, smoking cessation, physical exercise ≥30 min/day. A total of 102 patients (57%) were non-compliant (drug intake ≤80%, and did not fully follow lifestyle change recommendations). Results There were no significant differences at baseline between the two groups. Fuster-BEWAT score in 1 year was 9.83 ± 3.1 in compliant and 7.74 ± 2.9 in non-compliant patients ( p = 0.0001). At 1-year follow-up, there were 43 myocardial infarctions (40 patients (93%) were non-compliant) and 28 deaths (26 cases (92.8%) were non-compliant). Patients from the non-compliant group with three- and two-vessel obstructive CAD had higher 1-year MACE rate than those with one-vessel obstructive and non-obstructive CAD (95.24% and 70.5% versus 17.2% and 8.6%; p < 0.0001); more proximal coronary lesions were related to a worse prognosis. Conclusions Non-compliant diabetic patients had a tenfold increased risk for MACE within 1 year after TFA.

Coronary artery calcium score and coronary computed tomographic angiography for major perioperative cardiovascular complications in symptomatic diabetic patients undergoing trans-femoral amputation.

OBJECTIVE: Perioperative risk for major cardiovascular events (MACE) is particularly high in patients with type 2 diabetes undergoing surgery for trans-femoral amputation (TFA). The aim of this study was to identify prognostic value of coronary calcium score (CACS) and coronary computed tomographic angiography (CCTA) for perioperative MACE in these patients. METHODS: In this prospective single center interventional cohort study, we evaluated 331 consecutive symptomatic patients with diabetes and without history of coronary intervention or myocardial infarction (MI) undergoing TFA in 2013. 179/331 patients (54%) had no contraindications for CCTA and were included in the study cohort. RESULTS: All patients had revised cardiac risk index score of 3 or more points (class IV with MACE rate of 11%). Increasing calcium score was associated with increasing severity of CAD by CCTA and incidence of cardiovascular complications. During 25weeks of follow-up, there were 43 MACE (24%), 28(15.6%) of them cardiac death. Post-operative event rate increased in patients with increasing CACS from 10% with CACS 1-99 to 84% with CACS>1000 (p<0.001). Similarly, there were more post-operative events in patients with 3- and 2-vessels disease compared to 1-vessel obstructive and non-obstructive CAD (74.1% and 34.1% vs. 10.5% and 6.5%, p<0.001). CONCLUSIONS: Predicative value of CCTA and CACS is high for perioperative MI and death in patients with type 2 diabetes undergoing non-cardiac surgery for TFA. It may be considered as a valuable tool for preoperative risk assessment in these patients, where stress tests are not feasible and more sophisticated technical equipment is not available.
