OBJECTIVES: To determine the feasibility and efficacy of a laparoscopic approach to the radical retropubic prostatectomy (RRP). METHODS: A transperitoneal laparoscopic technique was developed to perform an RRP. Intra-abdominal access was obtained through five 10-mm trocars. After dissection of the prostate, the urethrovesical anastomosis was created via a transvesical approach. The prostate was removed by extending the umbilical incision. RESULTS: Between September 1991 and May 1995, nine laparoscopic RRPs were performed. The operative time averaged 9.4 hours. Only 1 of 9 patients had a positive surgical margin that involved the urethra. Six of 9 patients were completely continent postoperatively. Of the 4 patients who were potent preoperatively, 2 continued to have erections. There were three complications: cholecystitis, thrombophlebitis associated with a pulmonary embolism, and a small bowel hernia into a trocar site. CONCLUSIONS: Laparoscopic radical prostatectomy is feasible but currently offers no advantage over open surgery with regard to tumor removal, continence, potency, length of stay, convalescence, and cosmetic result.

With the advent and general acceptance of laparoscopy as a means of surgically treating intraabdominal disease processes, procedures on organs other than the gallbladder and female genital tract have slowly evolved. After developing basic techniques in an animal model, a clinical series (n = 19) of laparoscopic procedures for a variety of colonic lesions was undertaken and is herein presented. It included both malignant and nonmalignant disease processes and has carried an acceptable complication rate and survival. The average age of our patients was 68, and except for two extended postoperative hospitalizations and one death for non-procedure-related complications, the patients were generally ready for discharge in less than 96 hours. Our current techniques and indications for laparoscopic colonic surgery are detailed.

AIM: To examine job satisfaction and workplace engagement of millennial nurses. BACKGROUND: Millennial nurses are a rapidly growing segment of the workforce. They are significantly less satisfied in their jobs compared with nurses of other generations and are more likely to have perceptions that may negatively impact job satisfaction and engagement. It is important for nurse leaders to understand and value the perspective of these nurses to improve job satisfaction and engagement. METHOD: Exploratory-descriptive qualitative approach with 33 millennial nurses interviewed in nine focus groups. RESULTS: Five themes revealed areas that both enhance and hinder job satisfaction and engagement. Themes include the following: (1) professional relationships; (2) rewards; (3) communication; (4) professional development; and (5) workload/staffing. CONCLUSION: Concerns identified by millennial nurses provide direction for nurse leaders who are charged with fostering a workplace setting that nurtures empathy and respect for nurses of all generations. IMPLICATIONS FOR NURSING MANAGEMENT: Strategies to address preferences of millennials include employee rounding to ask about their needs, offer assistance and provide positive feedback. Ongoing mentoring regarding opportunities to support millennials' professional development includes offering participation in activities to advance evidence-based practice, preceptor training, financial assistance with national certification examinations and tuition reimbursement.

We report a laparoscopic approach to the drainage and ablation of symptomatic simple renal cysts. Ten patients with chronic pain, 6 of whom failed primary aspiration, underwent laparoscopic cyst ablation: 6 had solitary renal cysts, 3 had multiple cysts and 1 had a peripelvic cyst. The approach was transabdominal in 9 patients and extraperitoneal in 1. Intraoperatively, cyst fluid was obtained for cytological examination, and cyst walls were excised and sent for pathological examination. When possible, the remaining inner cyst walls were fulgurated to prevent recurrence. Mean total operating room time was 2 hours 27 minutes and blood loss was minimal. The sole complication was a postoperative retroperitoneal hematoma, which was managed conservatively. Malignancy was diagnosed in 2 patients, each of whom had a negative preoperative aspiration. These patients subsequently underwent radical nephrectomy. All remaining patients were asymptomatic at a mean followup of 10 months. Laparoscopic ablation of renal cysts is a safe and effective alternative to open surgery in patients who have failed conservative measures. Preoperative and intraoperative evaluation for malignancy should be performed.

Oral hygiene in seriously ill patients is a nursing responsibility. Oral hygiene regimens in conjunction with standardized ventilator-associated pneumonia "bundles" reduce the incidence of pneumonia, length of stay, and associated costs in critical care. Following strict adherence to the recommended ventilator-associated pneumonia bundle, the ventilator-associated pneumonia rate at the Northeast Baptist Hospital intensive care units has remained 0% for 36 months. Oral care in this patient population, however, has remained vague based on ritual and nurse preference. This article describes the development of an oral care protocol based on best evidence, providing a rationale for standardization of oral hygiene and the plan for surveillance and updating.

Abstract Background and Aims The role of dietary fat consumption in the etiology of hepatocellular carcinoma (HCC) remains unclear. We investigated the associations of total fat and fatty acids with risk of HCC among US adults in a hospital‐based case–control study. Methods We analyzed data from 641 cases and 1034 controls recruited at MD Anderson Cancer Center during 2001–2018. Cases were new patients with a pathologically or radiologically confirmed diagnosis of HCC; controls were cancer‐free spouses of patients with cancers other than gastrointestinal, lung, liver, or head and neck. Cases and controls were frequency‐matched by age and sex. Dietary intake was assessed using a validated food frequency questionnaire. Odds ratios (ORs) and corresponding confidence intervals (CIs) were computed using unconditional logistic regression with adjustment for major HCC risk factors, including hepatitis B virus and hepatitis C virus infection. Results Monounsaturated fatty acid (MUFA) intake was inversely associated with HCC risk (highest vs. lowest tertile: OR, 0.49; 95% CI, 0.33–0.72). Total polyunsaturated fatty acid (PUFA) intake was directly associated with HCC risk (highest vs. lowest tertile: OR, 1.82; 95% CI, 1.23–2.70). Omega‐6 PUFA was directly associated with HCC risk (highest vs. lowest tertile: OR 2.29; 95% CI, 1.52–3.44). Long‐chain omega‐3 PUFA (eicosapentaenoic acid and docosahexaenoic acid) intake was also inversely associated with HCC risk (highest vs. lowest tertile: OR, 0.50; 95% CI, 0.33–0.70). No association was observed for saturated fat and HCC risk. Conclusion Our findings support a direct association of omega‐6 PUFA intake with HCC and an inverse association of MUFA and long‐chain omega‐3 PUFA intake with HCC.

OBJECTIVES: To determine the sensitivity and specificity of a new myoglobin assay for acute myocardial infarction (AMI), considering both the total amount of serum myoglobin and its percentage change over 2 hours. METHODS: A prospective, observational test performance study for the recognition of AMI was done using serial myoglobin assays of 42 admitted chest pain patients at a large, urban teaching hospital ED. Myoglobin testing was performed at presentation (time 0) and at 1 and 2 hours after arrival. A myoglobin level > 100 micrograms/L (ng/mL) or a change > or = 50% from baseline (increase or decrease) any time during the 2-hour period was considered positive. Patients and their physicians were blinded to the myoglobin results. The managing clinician's final diagnosis of the presenting event was used as the diagnostic criterion standard. RESULTS: The sensitivity of the myoglobin technique for detection of AMI in the first hours in the ED was 13/14 (93%; 95% CI: 66-100%). The 1 patient who had a false-negative test had evidence of AMI on the ECG and an initially abnormal creatine kinase-MB (CK-MB) assay. The specificity was 22/28 (79%; 59-92%). However, of the 6 patients who had "false-positive" myoglobin tests, all had serious illness: significant cardiac disease (n = 4), in-hospital death (n = 1), or deep venous thrombosis (n = 1). CONCLUSION: Myoglobin level determinations are sensitive tests to detect AMI during the first 2 hours of a patient's stay in the ED and may complement current clinical tools.

BACKGROUND AND PURPOSE: Enrollment into acute stroke clinical trials is limited to experienced tertiary centers with emergency research infrastructure. Feasibility of remote enrollment via telemedicine into an acute thrombolytic clinical trial has never been demonstrated. METHODS: Using telemedicine, our hub stroke research center partnered with two spoke community hospitals to jointly participate in a randomized, phase III adjunctive thrombolysis clinical trial in the first 3 h after symptom onset to expand recruitment of the trial. Eligible patients were successfully identified, consented, randomized, and received therapy/placebo at the spoke hospitals under real-time direction by hub trialists via telemedicine. RESULTS: Ten patients were identified from May 2013 to July 2014, and six were enrolled via telemedicine. No study procedure delays, safety events, or major protocol violations occurred. CONCLUSIONS: It is feasible to randomize and enroll stroke patients via remote telemedicine into an acute thrombolytic clinical trial. This novel approach could expand access and accelerate completion of clinical trials if widely implemented.

PURPOSE: This phase 2 study compared OMS103HP (Omeros, Seattle, WA) with control (lactated Ringer's) irrigation solution in patients undergoing arthroscopic partial meniscectomy. METHODS: This was a prospective, multicenter, double-blind, randomized, vehicle-controlled, parallel-group study. Safety and postoperative pain, range of motion, and self-reported function were evaluated for 90 days. Statistical results were based on univariate analysis of variance and repeated-measures analyses. RESULTS: Mean visual analog scale (VAS) pain scores within 24 hours after discharge from the recovery room showed more pain in the control group beginning at 2 hours and peaking at 8 hours. Univariate analysis of variance of mean VAS scores over the 24-hour period did not meet statistical significance. Repeated-measures analysis yielded a statistically significant difference (P = .004) for time-by-treatment interaction, showing a clear drug benefit over time based on VAS scores. There were statistically significant differences at day 7 between the groups in passive flexion without pain (P = .022). The proportion of patients achieving flexion of 95° or greater, 110°, and 125° was greater for the OMS103HP group. The Knee Injury and Osteoarthritis Outcome Score (KOOS) showed statistically significant differences (P ≤ .05) between the OMS103HP and control groups for 4 of 5 outcomes (symptoms, pain, sport and recreation, and knee-based quality of life but not activities of daily living). All scores showed a treatment effect through day 90. The overall incidence of adverse events and abnormal laboratory values for the OMS103HP and control groups was similar. Serious adverse events occurred in 1 control patient. CONCLUSIONS: In this study of patients with meniscal tears who underwent simple debridement, the use of OMS103HP resulted in reduced acute postoperative pain (measured by VAS over the first 24 hours postoperatively), reduced pain during recovery (measured by the KOOS pain subscale, which measures both background levels of pain and exacerbations caused by movements or activities), improved postoperative knee motion, and improved functional outcomes as assessed with the KOOS Knee Survey. Clinical benefits of OMS103HP were consistent and sustained throughout 90 days of postoperative follow-up. LEVEL OF EVIDENCE: Level I, prospective, randomized, controlled trial.

INTRODUCTION: Preterm births account for disproportionately high healthcare costs, in large part due to expenses related to length of stay in the hospital neonatal intensive care unit (NICU). It is common for preterm infants to receive human milk fortifier (HMF) while in the NICU. Liquid HMF is available in both acidified and non-acidified formulations. A recent randomized clinical trial found that acidified HMF is associated with an increased incidence of metabolic acidosis, which may contribute to increased costs and longer NICU length of stay. OBJECTIVE: The present study is a secondary analysis of these data, seeking to determine whether additional factors contribute to metabolic acidosis, whether metabolic acidosis is associated with longer hospital length of stay, and whether these associations contribute to the burden of hospital costs. METHODS: The study sample consisted of 152 infants who were hospitalized in US NICUs. Multiple logistic regression was used to model the NICU length of stay. Data from the 2012 Healthcare Cost and Utilization Project (HCUP) Kids' Inpatient Database (KID) were used to calculate the average cost (charge) per day in a NICU. Costs (charges) were adjusted to $US, year 2018 values, using the health Consumer Price Index. RESULT: Results indicated that acidified HMF was a strong predictor of metabolic acidosis, more so than gestational age or birth weight. Furthermore, metabolic acidosis was associated with incremental NICU costs (charges) of $US19,002 ($US65,462) per infant and longer NICU LOS. CONCLUSION: Future studies should further investigate factors that contribute to NICU length of stay and associated costs of care. TRIAL REGISTRATION: ClinicalTrials.gov: NCT02307760.

Information and communication technology has left a print on all fields of life, including medicine and the health care system. Telemedicine is the perfect way to ensure adequate healthcare delivery to all people at any time, particularly during pandemics, regardless of any geographic or economic considerations. This article investigates the different types, categories, and benefits in addition to the barriers to telemedicine implementation, especially in the Middle East and North Africa (MENA) region. After a thorough review of medical literature related to telemedicine using PubMed, Google Scholar, and some other gray literature, it has been found that telemedicine has been involved in almost all medical specialties with a positive influence on healthcare delivery and medical education and research. It had a major role during the COVID-19 pandemic. However, many obstacles prevent its proper application and need to be addressed carefully by the government and relevant authorities. Due to the rapidly growing population, unequal distribution of healthcare services, and social distancing of the COVID-19 pandemic, the role of telemedicine has become increasingly essential. Regarding medical education and research, telemedicine facilitates the exchange of information and ideas between physicians and professionals from all over the world, bringing these various minds together on a single platform.

We read with great interest the manuscript written by Rosovsky et al1 entitled “Pulmonary embolism response teams: Purpose, evidence for efficacy, and future research directions.” We believe that the risk stratification, diagnostic approach, and therapeutic strategies from a given patient with suspected perioperative acute pulmonary embolism (PE) remain challenging for clinicians; thus, it is of paramount importance to actively involve a designated pulmonary embolism response team (PERT) in such difficult case scenarios, given its unique characteristics of being proactive, multidisciplinary, inclusive, and interactive, facilitating and leveraging multispecialty strengths and experience to come up with the best therapeutic strategy in an individualized manner and to make PERT performance better every time.2 We would like to share some questions and thoughts regarding the potential and future role of PERT in the special scenarios of perioperative PE. We strongly believe that the inclusion of a cardiovascular anesthesiologist with special skills in transesophageal and transthoracic echocardiography could be pivotal to activate PERT consultation, even intraoperatively, while the clinical pretest probability for acute PE is high. They can initiate diagnostic and therapeutic maneuvers in the operating room (OR). Do we know what percentage of PERT activations originated in the OR? As the PERT model gains wider acceptance, including among diverse surgical specialties (eg, general surgery, orthopedics, neurosurgery), more information should become available on whether PERT is a new standard of care in the complex clinical spectrum of venous thromboembolism as it affects surgical patients.3, 4 Provision of care to patients with perioperative acute PE is challenging. We believe that PERT, among other quality improvement efforts, will become an essential tool for surgeons and anesthesiologists who evaluate patients with suspected perioperative acute PE. PERT may result in effective and fast implementation of treatment, particularly in the intraoperative setting.

A group of 173 patients with abnormal cervical cytology underwent diagnostic or therapeutic conization following colposcopic examination. The series includes 23 patients with cold knife conization in the hospital under general anesthesia, 12 patients with an outpatient KTP laser procedure under local anesthesia, 53 patients with an outpatient CO2 laser procedure under local anesthesia, 10 patients with hospital-based loop radiothermal cautery conization and 75 patients with loop radiothermal cautery conization in the office under local anesthesia. Loop radiothermal cautery conization was advantageous, with a shorter duration of surgery, lower cost, reduced operative bleeding, less of a need for pain-relieving medication and shorter duration of postoperative disability. Cold knife conization patients had the most intraoperative bleeding and the longest hospitalization. KTP laser conization produced specimens of inferior quality, resulting in the least satisfactory histologic diagnosis. Office-based loop radiothermal cautery conization may be preferable to other methods of conization in the diagnosis and management of squamous intraepithelial lesions.

OBJECTIVE: This study examined the relationships between the dimensions of the nurse manager (NM) practice environment (PE) and burnout. BACKGROUND: NMs are critical to the success of their unit(s). Understanding the degree to which their PE characteristics impact their level of burnout is important to NM retention. METHOD: A cross-sectional research design using a 71-item questionnaire was used to measure NM characteristics, hospital characteristics, NM PE, and burnout. There were 110 completed respondents across 22 hospitals in the United States. RESULTS: Moderate inverse relationships exist between the NM PE and 2 of the 3 (work and personal) dimensions of burnout. NM age and tenure also showed an inverse relationship with burnout. CONCLUSIONS: This study added evidence showing a statistically significant relationship between NM PE and the work and personal dimensions of burnout. These results also suggest the relationships NMs have with the patients on their unit(s) do not add to their level of burnout.

Gastro-esophageal reflux disorder (GERD) is the most common gastrointestinal tract disorder with high morbidity and heavy economic burden. Despite being treated with high-dose proton-pump inhibitors or H2 receptor blockers, a considerable percentage of patients have GERD that is only partially controlled or refractory. The majority of these patients forego surgical treatment for fear of adverse outcomes, putting them at a financial disadvantage and causing loss of productivity. Untreated GERD is the sole known risk factor for developing Barrett's esophagus and esophageal adenocarcinoma if left untreated. With the advancement in therapeutic modalities in recent years, and given the issues such as medication compliance, the risk of adverse events with long-term antisecretory treatment, and fear of undergoing surgical treatment, endoscopic treatments such as Stretta and transoral incisionless fundoplication (TIF) have become a safe, cost-effective, and resilient option for the treatment of refractory GERD. Patients with refractory GERD ineligible for endoscopic therapies due to a large hiatal hernia can have their hiatal hernia corrected simultaneously with TIF (C-TIF). For the treatment of refractory GERD, endoscopic therapy is a viable and compelling option. Endoscopic therapies for refractory GERD patients are highly recommended due to their reproducible and standardized results as well as the potential to address the fundamental mechanical issue.

Evidence from preclinical and clinical studies suggests that human umbilical cord-derived mesenchymal stromal cells (HUC-MSCs) may be useful in treating heart failure and acute myocardial infarction (MI). However, the effects of stem cell therapy on patients with heart failure remain the subject of ongoing controversy, and the safety and effectiveness of HUC-MSCs therapy have not yet been proven. To date, there has been no systematic overview and meta-analysis of clinical studies using HUC-MSCs therapy for heart failure and MI. The purpose of this study is to assess the safety and efficacy of HUC-MSC therapy versus a placebo in patients with heart failure and MI. While preparing this systematic review and meta-analysis, we adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A computer literature search of PubMed was performed. We considered randomized controlled trials (RCTs) that reported data on the safety and efficacy of HUC-MSC transplantation in patients with heart failure and MI. Two investigators independently searched the literature, extracted data, and rated the quality of the included research. Pooled data were analyzed using the fixed-effect model or the random-effect model in Review Manager 5.3. The Cochrane risk of bias tool was used to assess the bias of included studies. The primary outcome was ejection fraction (EF), whereas the secondary outcomes were readmission and mortality rates. Three RCTs (201 patients) were included in this meta-analysis. The overall effect did not favor either of the two groups in terms of risk of readmission (risk ratio = 0.5, 95% confidence interval (CI) = 0.22-1.15, p = 0.10) as well as mortality rate (risk ratio = 0.44, 95% CI = 0.14-1.44, p = 0.18). However, there was an improvement in EF in patients who received HUC-MSCs compared to placebo after 12 months of transplantation (mean difference (MD) = 3.21, 95% CI = 2.91-3.51, p < 0.00001). At the six-month follow-up period, there was no significant improvement in EF (MD = 1.30, 95% CI = -1.94-4.54), p = 0.43), indicating that the duration of follow-up can shape the response to therapy. Our findings indicate that HUC-MSC transplantation can improve EF but has no meaningful effect on readmission or mortality rates. Existing evidence is insufficient to confirm the efficacy of HUC-MSCs for broader therapeutic applications. Therefore, additional double-blind RCTs with larger sample sizes are required.

Herpetic infections in body cavity fluids are unusual and are rarely reported in the cytology literature. We report a case of a 74-yr-old woman who developed ascites after undergoing an elective laparoscopic cholecystectomy for biliary colic. Cytology of peritoneal fluid revealed changes in a herpes simplex virus (HSV) infection that was confirmed by immunocytological staining.

BACKGROUND: Vascular endothelial growth factor inhibitors, including tyrosine kinase inhibitors (TKIs) and anti-angiogenics, are first-line therapies for advanced and metastatic hepatocellular carcinoma. Although TKIs have a greater potential for off-target adverse effects compared with bevacizumab (anti-angiogenics), a direct comparison of the risk of cardiovascular adverse events between these two types of therapies has not been performed. OBJECTIVE: To compare the incidence of and characterize cardiovascular adverse events in patients with hepatocellular carcinoma receiving TKIs versus bevacizumab. METHODS: This cohort study included adult patients with hepatocellular carcinoma who received first-line TKIs (sorafenib or lenvatinib) or bevacizumab at two academic medical centers and one community cancer center from September 2018 to August 2021. The primary outcome was risk of cardiovascular adverse events. Major secondary outcomes included the incidence of individual types of cardiovascular adverse events and risk factors associated with major adverse cardiovascular events (MACE). RESULTS: The study included 221 patients (159 TKI patients; 62 bevacizumab patients). At a median follow-up of 5 months, the probability of cardiovascular adverse events was not significantly different between the two groups (hazard ratio [HR]: 0.85; 95% confidence interval [95% CI]: 0.58-1.24; p = 0.390). The cumulative incidence of cardiovascular events was highest in patients receiving lenvatinib (sub-distribution hazard ratio [SHR]: 1.53; 95% CI: 1.02-2.30) compared with those receiving sorafenib (reference) or bevacizumab (SHR: 1.05; 95% CI: 0.68-1.64) after adjustment for comorbidities, liver transplant status, and presence of portal vein thrombosis at baseline. Cardiovascular adverse events were observed in 151 (68%) patients, and MACE were observed in 27 (12%) patients. Risk factors associated with MACE were hypertension (SHR: 3.5; 95% CI: 0.9087-15.83; p = 0.086), prior history of MACE (SHR: 2.01; 95% CI: 0.83-4.87; p = 0.124), and tobacco use (SHR: 2.85; 95% CI: 0.90-8.97; p = 0.074). CONCLUSIONS: Cardiovascular risk was not significantly different between TKIs and bevacizumab. Lenvatinib appears to have the highest risk of cardiovascular adverse events among these first-line VEGF inhibitors.

Coronary microvascular dysfunction (CMD) is becoming increasingly recognized as an important contributor to the development of ischemic heart diseases. Without obstructive coronary artery disease, the physiological function of the coronary microcirculation can be altered by structural, functional, and molecular factors, leading to myocardial ischemia. CMD can significantly impact the quality of life and prognosis and imposes a huge financial burden on healthcare systems and people. This meta-analysis aims to investigate the efficacy of angiotensin-converting enzyme inhibitors (ACEIs) for treating CMD. A systematic literature review identified randomized controlled trials (RCTs) comparing ACEIs with placebo in CMD patients. Review Manager, 5.3 for Windows, was utilized. Using the Mantel-Haenszel (M-H) method, improvement in coronary flow reserve (CFR) and systolic blood pressure events was pooled as mean difference (MD) in a meta-analysis model with a fixed effect model, whereas the number of chest pain episodes was pooled as MD with a random effect model. Five randomized controlled trials involving 209 patients were included in the analysis. The analysis demonstrated a statistically significant improvement in CFR in the ACEIs group compared to the placebo group (MD -0.3, 95% CI -0.61 to 0.01, P = 0.05). However, there was no significant difference in the number of chest pain episodes between the ACEIs and placebo groups (MD 1.79, 95% CI -3.99 to 7.58, P = 0.54). Similarly, no significant difference in blood pressure change was observed between the two groups (MD 4.02, 95% CI -3.25 to 11.28, P = 0.28). In conclusion, the appropriate treatment for CMD is a source of contention because adequate data is lacking. Our findings suggest that ACEIs may have a positive effect on improving CFR in patients with microvascular angina. However, ACEIs did not demonstrate a significant impact on the number of chest pain episodes or systolic blood pressure in this patient population. Further research, including RCTs with larger sample sizes and longer follow-up durations, is warranted to provide more conclusive evidence on the role of ACEIs in CMD management.

• The study explores the relationship between CUD and AIS risk among elderly PVD patients. • Of 5,115,824 geriatric PVD admissions, 21,405 had CUD. • Patients with CUD exhibited a 34 % increased risk of AIS hospitalizations compared to non-CUD patients. • The presence of CUD did not significantly impact all-cause in-hospital mortality. • Older PVD patients with concurrent tobacco use disorder surprisingly showed a protective effect against AIS. Further research is needed to understand this paradox effect. Given current evidence linking peripheral atherosclerotic disease, also known as cannabis arteritis, and acute ischemic stroke (AIS) in individuals with cannabis use disorder (CUD), we investigated the frequency and implications of CUD in relation to AIS risk and outcomes among elderly patients with peripheral vascular disease (PVD). The National Inpatient Sample (2016–2019) was used to compare geriatric patients with PVD and cannabis use disorder CUD. CUD was correlated with AIS admissions. Adjusted multivariable regression models assessed in-hospital mortality rates. Of 5,115,824 geriatric admissions with PVD, 50.6 % were male and 77.5 % were white. 21,405 admissions had cardiovascular and CUD co-occurrence. 19.7 % of CUD patients had diabetes mellitus (DM), compared to 33.7 % of non-CUD patients. Smoking and HTN rates were comparable between groups. Patients with CUD used more recreational drugs concurrently than those without CUD. AIS prevalence was 5.2 % in CUD patients and 4.0 % in controls ( p < 0.001). In the geriatric population with PVD, the presence of CUD was found to be associated with increased odds of hospitalizations due to AIS, with an adjusted odds ratio (aOR) of 1.34 (95 % confidence interval [CI] 1.18–1.52, p < 0.001). All-cause in-hospital mortality was not statistically significant, with an aOR of 0.71 (95 %CI 0.36–1.37, p = 0.302). In our study, older patients with PVD and hypertension (aOR 1.73) had a greater risk of AIS. Intriguingly, when we analyzed AIS predictors in elderly PVD patients with concurrent tobacco use disorder, we identified a counterintuitive protective effect (aOR 0.58, 95 % CI 0.42-0.79, p < 0.001). Our findings indicate that among geriatric patients with PVD and concurrent CUD, there is a notable 34 % risk of AIS. Importantly, this risk persists despite controlling for other CVD risk factors and substance use. Further investigations are warranted to elucidate and validate the intriguing phenomenon known as the smoker's paradox.
