Cisgender cellular tissue-based products improve wound healing.

Neither the CTP sex effect of female CTP derived from cryopreserved human placental membranes, nor male CTP bioengineered from living human keratinocytes and foreskin fibroblasts has been described. Healing in wounds was examined to establish the CTP sex' s role in both males and females. Cisgender CTP wounds had better closure. Overall, male PC, PC-End, and CC rates over time were better than female rates. Outcomes were affected by access, etiology, and follow-up.

An objective comparative study of non-surgical cleansing techniques and cleanser types in bacterial burden management.

Cleansing is a vital component of effective wound hygiene and biofilm management, often accomplished through vigorous mechanical action or through soaking with moistened gauze. In the present study, a quantitative comparison of the effectiveness of different cleansing techniques and solutions in removing bacteria was conducted on 71 chronic wounds using bacterial fluorescence imaging as a real-time diagnostic for moderate to high bacterial loads. Vigorous gauze cleansing for 30 s proved most effective by reducing bacterial fluorescence by 33.99%, surpassing 10-min soaking in bacterial reduction (13.24%). Among different cleansers, no statistically significant differences in effectiveness were observed, but povidone-iodine showed the strongest trend towards bacterial reduction. Sub-analysis highlighted the superiority of antiseptic cleansers over saline and gentle soap (-33.30% vs. -1.80% bacterial reduction respectively). Five percent acetic acid was also shown to be more effective in removing specific bacterial strains (Pseudomonas aeruginosa). Findings from studies like this contribute to refining wound hygiene guidelines and clinical algorithms for bacterial and biofilm management.

Revisiting Heinz-Lippman disease as a complication of chronic venous insufficiency.

Chronic venous insufficiency with and without ulceration is a common complication of varicose veins. Heinz-Lippmann disease is a potentially underreported complication of chronic venous insufficiency that involves heterotopic ossification of the peri-wound that might contribute to the chronicity of venous leg ulcers. Most commonly, heterotopic ossification is associated with traumatic injury. We report the cases of three patients with chronic venous insufficiency and no history of trauma who were found to have subcutaneous calcifications consistent with Heinz-Lippmann disease. Osteomyelitis was confirmed in two patients. Physical examination and diagnostic imaging can be helpful in determining the diagnosis. Interventions can include biopsy to rule out osteomyelitis, with subsequent treatment, if needed.

Fetal bovine acellular dermal matrix in the management of chronic nonhealing lower extremity wounds.

BACKGROUND: The management of chronic nonhealing lower extremity wounds remains a problem that substantially affects patients and significantly burdens the health care system. Nonhealing wounds lead to increased hospitalization, decreased quality of life, minor and major amputations, and increased risk of mortality. Dermal matrices have advanced the science of wound healing. PURPOSE: To evaluate fetal bovine acellular dermal matrix (FBADM), an acellular dermal collagen repair scaffold derived from fetal bovine dermis, in the management of chronic nonhealing lower extremity wounds. METHODS: A single-center retrospective chart review was conducted to collect data on patients with chronic nonhealing lower extremity wounds treated with FBADM from January 2013 through December 2019. RESULTS: A total of 43 patients were enrolled, with a mean age of 68.5 years and a mean wound area of 27 cm2. Complete closure of the wound occurred in 53% of patients overall, with 28% of patients achieving healing within 12 weeks. CONCLUSION: Application of FBADM in the management of chronic nonhealing lower extremity wounds is safe, effective, and efficient.

Comparing U.S. and Canadian treatment patterns on venous thromboembolism outcomes in the GARFIELD-VTE registry.

BACKGROUND: Economically developed countries continue to find that venous thromboembolism (VTE) is a major cause of morbidity and mortality. OBJECTIVE: To compare baseline risk profiles and patient workflow patterns between the United States (U.S.) and Canadian management of VTE patients from 2014 to 2017. METHODS: The Global Anticoagulant Registry in the FIELD (GARFIELD-VTE) is a prospective, observational study of 10,679 patients with objectively confirmed VTE, followed for 3 years. In total 1101 patients enrolled in the U.S. and Canada were included in this analysis. RESULTS: Median age and body mass index were comparable between the U.S. (60.5; 30.2) and Canadian (59.7; 29) patients. A higher percentage of U.S. patients were black (n = 128, 24.1 %; n = 22, 3.9 %) and had a higher VTE-associated risk profile, including immobilization, hospitalization, and recent surgery. U.S. patients had a higher combined DVT and PE primary diagnoses (20.3 %) and were more likely to be treated in hospitals (77.2 %) than Canadians (13.3 %; 48.1 %). Direct oral anticoagulant therapy (DOAC) was nearly two-fold more frequent in Canadian patients (n = 218, 39.2 %) at the end of 3 years in comparison to the U.S. (n = 118, 23.0 %). Adjusted for sex, recent bleed event, heart failure, chronic immobilization, family history of VTE, history of cancer and prior VTE, and renal insufficiency, the risk of all-cause mortality was 51.9 % higher in patients from the U.S. compared to those in Canada after 3 years. Patients from the U.S. also had a higher likelihood of hospitalization, major bleeding, and recurrent VTE after controlling for prior history and comorbid conditions. CONCLUSION: Higher rates of adverse VTE-associated outcomes in the U.S. may be attributed to different baseline risk profiles, facility care, and distribution of specialists and their subsequent treatment strategies. TYPE OF RESEARCH: Global, multicentre, non-interventional, prospective registry titled Global Anticoagulant Registry in the FIELD - Venous Thromboembolism (GARFIELD-VTE). KEY FINDINGS: 531 U.S. and 557 Canadians patients included in study. DOAC use more frequent in Canadian patients after 3 years than U.S. (39.2 % vs. 23.0 %, respectively). Adjusted for sex, recent bleed event, heart failure, chronic immobilization, family history of VTE, history of cancer and prior VTE, and renal insufficiency, all-cause mortality risk remained higher in U.S. patients vs. Canadian patients after 3 years. U.S. patients had higher likelihood of hospitalization, major bleeding, and recurrent VTE. TAKE-HOME MESSAGE: Higher rates of adverse VTE-associated outcomes in the U.S. may be attributed to different baseline risk profiles, facility care, and composition of specialists and their subsequent treatment strategies. TABLE OF CONTENTS SUMMARY: Global, multicentre, non-interventional, prospective registry titled Global Anticoagulant Registry in the FIELD - Venous Thromboembolism (GARFIELD-VTE). Higher rates of adverse VTE-associated outcomes were observed in U.S. patients vs Canadian patients, which may be attributed to different baseline risk profiles, facility care, and distribution of specialists and their subsequent treatment strategies.

Reducing lower extremity hospital-acquired pressure injuries: a multidisciplinary clinical team approach.

OBJECTIVE: Optimal methods of reducing incidence of hospital-acquired pressure injuries (HAPIs) remain to be determined. We assessed changes in yearly incidence of lower extremity HAPIs before and after an intervention aimed at reducing these wounds. METHOD: In 2012, we implemented a three-pronged intervention to reduce the incidence of HAPIs. The intervention included: a multidisciplinary surgical team; enhanced nursing education; and improved quality data reporting. Yearly incidence of lower extremity HAPIs was tracked. RESULTS: Pre-intervention, incidence of HAPIs was 0.746%, 0.751% and 0.742% in 2009, 2010 and 2011, respectively. Post-intervention, incidence of HAPIs was 0.002%, 0.051%, 0.038%, 0.000% and 0.006% in 2013, 2014, 2015, 2016 and 2017, respectively. Mean incidence of HAPIs was reduced from 0.746% before the intervention to 0.022% after the intervention (p<0.001). CONCLUSION: An intervention by a multidisciplinary surgical team enhanced nursing education, and improved quality data reporting reduced the incidence of lower extremity HAPIs.

Lessons Learned: A Disruption in Care Leads to Increased Rates of Proximal Amputations.

BACKGROUND: In March 2020, due to the COVID-19 pandemic, hospitalizations in New York state were restricted to emergency purposes. Non-COVID related cases involving lower extremity wounds were only admitted for acute infections and limb salvage. Patients with these conditions were placed at higher risk for eventual limb loss. PURPOSE: To understand the impact of COVID-19 on amputation rates. METHODS: A retrospective review of lower limb institution-wide amputations was conducted at Northwell Health from January 2020 to January 2021. The amputation rates during the COVID-19 shutdown period were compared to the pre-pandemic, post-shutdown, and reopening period. RESULTS: The pre-pandemic period had 179 amputations, of which 8.38 % were proximal. 86 amputations were performed during shutdown, with a greater proportion being proximal (25.58 %, p=0.0009). Following the shutdown period, amputations returned to baseline. The proportion of proximal amputations during post-shutdown was 18.5 % and during reopening was 12.06 %. Patients had 4.89 times higher odds of undergoing a proximal amputation during the shutdown period. CONCLUSIONS: The effect of COVID-19 on amputation rates demonstrates an increase in proximal amputation during the initial shutdown. This study suggests an indirect negative effect of COVID-19 hospital restrictions on surgeries during the initial shutdown period.

Predictors of poor outcomes after lower extremity revascularization for acute limb ischemia.

OBJECTIVES: Acute lower extremity ischemia is one of the most common emergencies in vascular surgery and is a cause of considerable morbidity and mortality. The goal of this study was to evaluate outcomes of revascularization for acute lower extremity ischemia and to determine factors associated with perioperative morbidity and mortality. METHODS: A total of 354 patients underwent urgent revascularization for acute lower extremity ischemia at an academic medical center between 2014 and 2019. A retrospective review of patients' demographics, comorbidities, etiology and severity of limb ischemia, and procedural characteristics was recorded. Outcomes, including postoperative complications, perioperative limb loss, and mortality, were analyzed. RESULTS: The mean patient age was 69 ± 17 years, and 52% were females. 50% of patients presented with Rutherford Class IIb ischemia. Arterial embolization was the most common cause of limb ischemia, seen in 33% of cases. Open surgical revascularization was performed in 241 (68%) patients, while endovascular and hybrid approaches were utilized in 53 (15%) and 60 (17%) cases, respectively. Postoperative adverse events occurred in 44% of patients, including wound complications (11%), cardiac (5%) and pulmonary (16%) complications, strokes (4%), UTIs (10%), renal failure (14%), bleeding (5%), and compartment syndrome (3%). The rate of unplanned return to the operating room was 21%. Major adverse cardiovascular events were seen in 103 (29%) patients and major adverse limb events were seen in 57 (16%) patients. The median length of stay was 10 days (IQR = 4); 49% patients were discharged to skilled nursing facility and 19% were readmitted within 30 days.The rate of amputation during index admission was 10%, and perioperative mortality was 20%. Gender, tibial runoff, and etiology of limb ischemia were independent predictors of limb loss. Women had lower risk of limb loss than men (OR, 0.11; 95% CI, 0.023, 0.38). Poor tibial runoff (one-vessel or absence of flow below the knee) was a significant predictor of limb loss as compared to three-vessel runoff (OR, 14.92; 95% CI, 1.92, 115.88). Aneurysmal disease (OR, 38.35; 95% CI, 3.54, 42.45) and traumatic injuries (OR, 108.08; 95% CI, 8.21, 159.06) were the strongest predictors of amputation as compared to other etiologies of limb ischemia. Multivariate model identified ESRD (OR, 9.2; 95% CI, 1.8-46.3), degree of ischemia (class IIb or higher vs class IIa; OR, 3.5; 95% CI, 1.2-10.6), and age (OR, 1.5; 95% CI 1.1-2.0 for every 10 years) as independent predictors of perioperative mortality. CONCLUSIONS: Urgent revascularization for management of acute limb ischemia is associated with high morbidity and mortality. Elderly patients with ESRD presenting with severely threatened limbs have especially high risk of perioperative mortality and may not be ideal candidates for limb salvage.

This article provides a comprehensive review of chronic venous insufficiency outlining the anatomy, pathophysiology, clinical presentation, assessment and management options.

Virtual Events in the Era of COVID-19: Perspectives From a Virtual Interdisciplinary Wound Care Symposium.

BACKGROUND: The coronavirus disease-19 pandemic has created changes in the way medicine is practiced. The move to virtual conferencing to avoid mass gatherings is a significant change to how health care professionals meet, discuss current trends, and share research. METHODS: Data from exit polls conducted after annual wound care symposiums were reviewed. Physicians, nurses, podiatrists, and other health care professionals attended. Respondents were asked to comment and reflect on their experiences of attending a virtual conference. RESULTS: Over 60% of all (N = 283) respondents stated the virtual conference was better than or on par with a live event. Many respondents had attended this live event in person in previous years. Of all respondents, 83% stated that they planned to access conference materials for the 30 days they remained posted after the event. More than 50% of respondents stated they favored the ability to communicate effectively with colleagues via the instant messaging feature offered by the conference. Approximately 80% of respondents stated that they would like to attend this and other conferences virtually in the future. CONCLUSIONS: The shift from in-person to virtual conferences has the potential to remain a significant method of attending health care conferences. Conference organizers are encouraged to consider how they can implement virtual components, including postconference access to materials, to enhance the conference experience. Additional work needs to be done to understand the impact of the virtual format on knowledge retention.

Laboratory and Pharmaceutical Data Associated With Hospital Readmission in Persons With Diabetic Foot Ulcers.

Purpose: Diabetic foot ulcers (DFUs) are a leading cause of lower extremity amputations among persons with diabetes (PWD) and a common cause of hospitalizations. This study identified demographic characteristics, lab values, and comorbidities associated with 30-day and 90-day hospital readmission in persons with DFU.Methods: A retrospective chart review at our institution examined 397 patients with type 2 diabetes admitted with DFU between January 2014 and December 2018. Variables were analyzed using descriptive statistics, t-tests, and logistic regressions.Results: None of the studied demographic, laboratory (including Hemoglobin A1c) or comorbid diseases were associated with 30-day readmission in persons with DFU. Risk factors for 90-day readmission included discharge location to home with health care (OR: 2.62, 95% CI: 1.39, 4.95), anticoagulant use (OR: 2.36, 95% CI: 1.27, 4.39), and SQ insulin use (OR: 2.08, 95% CI: 1.20, 3.61).Conclusions: None of the variables examined were associated with 30-day readmission; however, potential predictors for 90-day readmission included anticoagulation or insulin use and discharge home with healthcare services. Future studies should devise interventions to improve transition of care in patients with DFU to further assess the role of medications and home health care as a potential predictor of 90-day hospital readmission.

Evaluating the Need of Continuing the Antiplatelet Drug Therapy in Patients Undergoing Minor Oral Surgical Procedures.

BACKGROUND: Dental treatment in patients on antiplatelet drug therapy is a long standing debate. Discontinuation of medication increases the risk of thrombotic complications, whereas continuation leads to increased postoperative bleeding. AIM: We conducted this prospective cross-sectional study to assess risk of bleeding in patients continuing antiplatelet medication while performing minor oral surgical procedures such as single or multiple teeth extraction, transalveolar extraction of third molar, biopsy, and alveoloplasty. MATERIALS AND METHODS: We calibrated the steps taken to achieve hemostasis, time taken to arrest bleeding, and correlated time taken to achieve hemostasis in patients under antiplatelet drug therapy (Group A [n = 64] - aspirin, Group B [n = 36] - aspirin and clopidogrel) and in patients without any drug therapy (Group C [n = 100] healthy patients). RESULTS: Out of 200 patients, Level 1 hemostatic measures were required for 129 (64.5%) patients, Level 2 hemostatic measures were taken for 68 (34.0%) patients, and Level 3 hemostatic measures were taken for 3 (1.5%) patients. Chi-square test conducted to compare the local hemostatic measures taken for minor oral surgical procedure for all groups was statistically significant (P ≤ 0.001). CONCLUSION: Overall, there was no postoperative bleeding within 24 h of extraction in any patient group. In conclusion, surgical procedures can be safely accomplished in patients receiving single or dual antiplatelet therapy when appropriate local hemostatic measures are taken.

An Interdisciplinary Team Approach to Decrease Sacral Hospital-acquired Pressure Injuries: A Retrospective Cohort Study.

BACKGROUND: Hospital-acquired pressure injuries (HAPIs) of the sacrum are among the most common iatrogenic events in health care. Multi-intervention programs have been shown to decrease the prevalence of pressure injuries. PURPOSE: To assess changes in the yearly incidence of sacral HAPIs before and after implementation of a 3-pronged interdisciplinary intervention to reduce HAPI incidence. METHODS: A retrospective study of all patients admitted between 2010 and 2017 was conducted to evaluate the effect of a 2012 initiative on the incidence of sacral HAPIs. In 2012, an interdisciplinary team was created, and enhanced education programs for nursing staff and quality data reporting measures were implemented for all patients admitted to North Shore University Hospital, Manhasset, NY. Pre- and post-intervention patient variables and sacral HAPI outcomes were compared. RESULTS: Pre- intervention, the sacral HAPI incidence was 0.353% and 0.267% (mean 0.31%) in the years 2010 and 2011, respectively. Post-intervention the HAPI incidence was 0.033%, 0.043%, 0.008%, 0.007%, and 0.004% in the years 2013, 2014, 2015, 2016, and 2017, respectively (mean 0.019%) (2-sample unpaired t-statistic: 11.5937; P < .001). Significant variables and outcomes differences between pre-intervention (n = 245) and post-intervention (n = 49) patients with a sacral HAPI were seen for race (P < .0001), length of stay (P = .0096), and HAPI stage (P < .0001). CONCLUSION: A hospital-wide, multi-part, interdisciplinary intervention resulted in a significant and sustained reduction in the incidence of sacral HAPIs.

Human Amnion Chorion Membrane Allografts in the Treatment of Chronic Diabetic Foot Ulcers: A Literature Review.

OBJECTIVE: To discuss human amnion chorion (placental) membrane allograft (HACMA) use for the treatment of chronic diabetic foot ulcers (DFUs) and to evaluate the effectiveness, cost, and product waste of this therapy. DATA SOURCES: PubMed, Cochrane, and OVID databases. STUDY SELECTION: Twenty-four articles pertaining to HACMA and DFUs published from 2016 to 2020 were selected. DATA EXTRACTION: The data collected included type of wound care product, study design, study size, baseline size of DFU, cost, product wastage, number of applications, and wound healing outcomes. DATA SYNTHESIS: Human amnion chorion membrane allografts in the treatment of chronic DFUs have led to a reduction in healing time and increased the overall percentage of healing, making them more effective in treating DFUs compared with standard of care. These products are offered in multiple sizes with various shelf lives and methods of storage, making them accessible, easy to use, less wasteful, and lower in cost compared with other commercially available products. Promising evidence demonstrates that HACMAs are beneficial in treating complex, high-grade DFUs with exposed tendon or bone. CONCLUSIONS: Human amnion chorion membrane allografts are effective in treating chronic DFUs with a greater percentage of complete wound closure and a reduction in healing time versus standard of care.

Maturation Rates of Arteriovenous Fistulas Using Small Veins in the Era of Endovascular Interventions.

BACKGROUND: Traditional practice suggests the abandonment of veins smaller than 3 mm in diameter for arteriovenous fistula (AVF) creation because of a low rate of maturation. This study aims to show that with balloon-assisted maturation (BAM), undersized veins can be used to create functional AVFs with a high rate of success. METHODS: All patients who underwent AVF creation between 2014 and 2018 at a tertiary academic medical center were retrospectively reviewed. The patients without preoperative vein mapping, those who failed to follow-up, and the patients who were not on dialysis were excluded. A fistula was considered to be mature if it was successfully cannulated for dialysis. A total of 596 patients were identified for analysis. The cohort was divided into the small-vein group (SVG, <2.5 mm) and large-vein group (LVG, ≥2.5 mm) based on preoperative vein size. Categorical variables were analyzed with the chi-squared test for their association with maturation status. Continuous variables were analyzed with the Wilcoxon rank sum test. A P-value less than 0.05 was considered significant. RESULTS: In the study cohort, 61.9% of the patients were male, with an average age of 62.8 ± 13.7 years, and an average preoperative vein size of 2.9 ± 1.1 mm. With similar demographic distribution, the participants in the SVG (n = 216) had significantly smaller preoperative vein size of 1.9 ± 0.4 mm than the patients in the LVG (n = 380), 3.5 ± 0.8 mm (P = 0.001). There were significantly more radio-cephalic AVFs created in the SVG (77.8% versus 48.7%, P < 0.0001). The overall maturation rate was 83.1% (n = 495), 219 fistulas (36.7%) matured primarily and 276 (46.3%) required interventions. Ninety-one percent of the patients required only 1 or 2 BAMs to achieve maturation. The SVG achieved a maturation rate of 75.9% as compared with 87.1% in the LVG (P = 0.002). A significantly higher number of patients in the SVG required BAM for maturation as compared with the LVG (67.7% versus 49.9%, P = 0.0002); however, there was no difference in the average number of BAMs required for fistula maturation between the groups (1.5 ± 0.8 for the SVG vs. 1.4 ± 0.7 for the LVG). In multivariable logistic regression analysis, vein size ≥2.5 mm (odds ratio (OR) = 2.11, confidence interval (CI): 1.36-3.27, P = 0.0009) and male sex (OR = 2.30, CI: 1.49-3.57, P = 0.0002) were independent predictors of maturation. CONCLUSIONS: Small veins can be used for AVF creation with lower but still favorable maturation rates using BAM interventions, especially in male patients. This practice can increase the creation of autogenous dialysis access and potentially reduce complications related to prosthetic dialysis access.

The Role of Duplex Ultrasound in Assessing AVF Maturation.

BACKGROUND: Arteriovenous fistulas (AVFs) are favored for hemodialysis (HD) access. However, in many instances, AVFs fail to mature. We examined the utility of postoperative color duplex ultrasound (CDU) in assessing AVF maturation and determining the need for balloon-assisted maturation (BAM). METHODS: A total of 633 patients underwent AVF creation at a single institution from 2015 to 2018. A total of 339 patients (54%) underwent CDU at a median of 8 weeks postoperatively. We collected the following parameters: vein diameter, volume flow (VF), peak systolic velocities in arterial inflow and venous outflow, and presence of stealing branches. A peak systolic velocity ratio (SVR) of ≥2 correlated with ≥50% stenosis in venous outflow, and SVR ≥3 correlated with ≥50% stenosis at the anastomosis. AVFs were considered mature when they were successfully cannulated on dialysis. A generalized linear mixed model (GLMM) was created to compare duplex criteria associated with successful use of AVF (maturation) to those AVFs that required further intervention or failed to mature. Fistulography images, the current gold standard, were compared with findings from CDU studies to determine validity of the duplex ultrasound. RESULTS: Of the 339 AVFs with postoperative CDU, 31.3% matured without interventions, 38.3% required BAM, 9.7% thrombosed, and the remaining patients were not yet on HD. Based on GLMM analysis, the probability of AVF maturation increases if CDU demonstrated one of the following: the vein diameter is ≥ 6 (odds ratio [OR] = 38.7), no evidence of stenosis in the venous outflow tract (OR = 35.6), no stealing branches (OR = 21.6) and VF ≥ 675 (OR = 5.0). Fistulography was performed in 195 patents. Sensitivity and specificity for each are as follows: vein diameter (84.3%, 28.6%), stenosis (59.3%, 78.8%), and stealing branches (20.7%, 92.7%). CONCLUSIONS: Postoperative CDU should be considered routine to correct anatomical findings that might limit AVF maturation and identify the need for further interventions.

Current Concepts in the Diagnosis and Management of Lymphedema.

GENERAL PURPOSE: To present a comprehensive review of lymphedema, including its pathophysiology, assessment, diagnosis, and treatment. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant will:1. Summarize the etiology, pathophysiology, and clinical manifestations of lymphedema.2. Describe the diagnostic and treatment approaches for patients who have lymphedema. ABSTRACT: Lymphedema is a condition characterized by localized protein-rich swelling caused by damaged or malfunctioning lymphatics. Patients with lymphedema have an increased risk of infection because of the lymphostatic nature of the disease. Chronic ulceration of the skin can make individuals vulnerable to infection leading to serious, sometimes fatal, complications. Proper diagnosis and treatment modalities can aid in the prevention of these complications and ensure better outcomes for the patient.

Nigella sativa and Trigonella foenum-graecum Supplemented Chapatis Safely Improve HbA1c, Body Weight, Waist Circumference, Blood Lipids, and Fatty Liver in Overweight and Diabetic Subjects: A Twelve-Week Safety and Efficacy Study.

In 2019, ∼ 463 million people globally had diabetes mellitus (DM), with China (25.1%), India (16.6%), and the United States (6.69%) representing nearly 50% of that total. The primary objectives of this exploratory study were to assess the safety and potential efficacy of Nigella sativa and fenugreek seed supplemented chapatis in overweight (OW) and type 2 DM subjects. Forty subjects (15/OW; 9/DM; 16/DM/OW) consumed two chapatis twice a day 6 days/week for a daily dose of 5.45 g of an N. sativa/fenugreek combination over 12 weeks with no changes in lifestyle or medications. Anthropometric, glycemic, and vascular variables were recorded at baseline and after 6 and 12 weeks. Glycated hemoglobin (HbA1c), plasma lipids, and complete metabolic profile were measured at baseline and termination. Compliance, estimated during twice-daily individual delivery of precooked chapatis, was 100%, with no significant adverse effects. At termination, body weights, body mass index, waist and hip circumferences, index of central obesity, HbA1c, fasting blood glucose, 2-h postprandial blood glucose, estimated average glucose over 12 weeks, total cholesterol (TC), non-high density lipoprotein (HDL) cholesterol, very low density lipoprotein (VLDL), and triglycerides (TG) were decreased (P < .05) over all subjects. Subjects with HbA1c ≥7.0 exhibited greater improvements in all glycemic variables than HbA1c <7.0 subjects. In addition, the decrease in HbA1c was positively correlated with decreases in (1) hepatic enzymes alkaline phosphatase (r = 0.301, P = .0067) and aspartate transaminase (r = 0.277, P = .0129), (2) systolic blood pressure (r = 0.388, P = .0004), and (3) number of diagnostic metabolic syndrome criteria exhibited per subject (r = 0.391, P = .0005), cardiovascular risk score (CRS) (r = 0.281, P = .0115), and hepatic steatosis index (HSI) (r = 0.223, P = .0467). Atherogenic and diabetogenic indexes TC/HDL, low density lipoprotein/HDL, VLDL/HDL, and TG/HDL were all decreased (P < .05). Among all subjects, improvement (P < .05) was seen in CRS (-10.7%), fatty liver index (-19.8%), lipid accumulation product (-13.8%), and HSI (-7.53%). N. sativa/fenugreek supplemented chapatis present a safe and seamless dietary modification to address cardiometabolic risk.
