COVID-19 associated mortality and cardiovascular disease outcomes among US women veterans
2021
The burden of COVID-19 has been noted to be disproportionately greater in minority women, a population that is nevertheless still understudied in COVID-19 research. We conducted an observational study to examine COVID-19-associated mortality and cardiovascular disease outcomes after testing (henceforth index) among a racially diverse adult women veteran population. We assembled a retrospective cohort from a Veterans Affairs (VA) national COVID-19 shared data repository, collected between February and August 2020. A case was defined as a woman veteran who tested positive for SARS-COV-2, and a control as a woman veteran who tested negative. We used Kaplan–Meier curves and the Cox proportional hazards model to examine the distribution of time to death and the effects of baseline predictors on mortality risk. We used generalized linear models to examine 60-day cardiovascular disease outcomes. Covariates studied included age, body mass index (BMI), and active smoking status at index, and pre-existing conditions of diabetes, chronic kidney disease (CKD), chronic obstructive pulmonary disease (COPD), and a history of treatment with antiplatelet or anti-thrombotic drug at any time in the 2 years prior to the index date. Women veterans who tested positive for SARS-CoV-2 had 4 times higher mortality risk than women veterans who tested negative (Hazard Ratio 3.8, 95% Confidence Interval CI 2.92 to 4.89) but had lower risk of cardiovascular events (Odds Ratio OR 0.78, 95% CI 0.66 to 0.92) and developing new heart disease conditions within 60 days (OR 0.67, 95% CI 0.58 to 0.77). Older age, obesity (BMI > 30), and prior CVD and COPD conditions were positively associated with increased mortality in 60 days. Despite a higher infection rate among minority women veterans, there was no significant race difference in mortality, cardiovascular events, or onset of heart disease. SARS-CoV-2 infection increased short-term mortality risk among women veterans similarly across race groups. However, there was no evidence of increased cardiovascular disease incidence in 60 days. A longer follow-up of women veterans who tested positive is warranted.

The current study assessed performance of the new Veterans Affairs (VA) women cardiovascular disease (CVD) risk score in predicting women veterans’ 60-day CVD event risk using VA COVID-19 shared cohort data. The study data included 17,264 women veterans—9658 White, 6088 African American, and 1518 Hispanic women veterans—ever treated at US VA hospitals and clinics between 24 February and 25 November 2020. The VA women CVD risk score discriminated patients with CVD events at 60 days from those without CVD events with accuracy (area under the curve) of 78%, 50%, and 83% for White, African American, and Hispanic women veterans, respectively. The VA women CVD risk score itself showed good accuracy in predicting CVD events at 60 days for White and Hispanic women veterans, while it performed poorly for African American women veterans. The future studies are needed to identify non-traditional factors and biomarkers associated with increased CVD risk specific to African American women and incorporate them to the CVD risk assessment.

Impact of a Quality Improvement Initiative on Medical Management of Veterans With Peripheral Artery Disease
2024
Guideline-directed medical therapy (GDMT) for peripheral artery disease (PAD) remains severely underused. Prevention of Amputation in Veterans Everywhere (PAVE) is a screening program designed to prevent or delay major lower extremity amputation. This study aimed to determine whether diagnosis of PAD through the PAVE program improves the prescription of GDMT in veterans with asymptomatic PAD. Patients enrolled into the PAVE program from our institution from 2020 to 2021 were included. Patients with an abnormal ankle-brachial index (ABI), defined as ABI <0.9 or >1.2, were selected for further analysis. Primary outcome was adherence to GDMT, following class I and class IIa recommendations. Secondary outcomes included changes in low-density lipoprotein (LDL), blood pressure, and hemoglobin A1c (HbA1c). A total of 6,313 patients were enrolled into the PAVE program between 2020 and 2021. Of these, 211 had abnormal ABI and were included in our analysis. With enrollment into PAVE, there was significant increase in the prescription of aspirin (74.4% vs 64.9%, p = 0.044) and statins (91.5% vs 82%, p = 0.006). The overall adherence to GDMT significantly increased (56.9% vs 38.9%, p <0.001). The number of patients needed to enroll in PAVE to improve GDMT adherence is 5.6 (95% confidence interval 3.6 to 12.3). Patients enrolled into PAVE program saw significant decreases in HbA1c, with mean decrease of 0.3 (p = 0.012) and a decrease in LDL, with a mean decrease of 6.2 (p = 0.01). In conclusion, enrollment into an amputation prevention program secondarily increased adherence to GDMT, driven by increases in the prescription of statins and aspirin, with resulting decreases in HbA1c and LDL.
Enrollment in an amputation prevention program through a quality improvement initiative (Prevention of Amputation in Veterans Everywhere program) secondarily improved low-density lipoprotein cholesterol levels and glycemic control in veterans with peripheral vascular disease. Future studies are needed to investigate the impact on mortality.

For endovascular treatment of below-the-knee (BTK) peripheral artery disease (PAD), independently adjudicated real-world outcomes comparing non–stent-based balloon angioplasty (percutaneous transluminal angioplasty) and adjunctive treatments with or without a concomitant ipsilateral femoropopliteal (FP) artery intervention are scarce. A total of 1,060 patients from the multicenter XLPAD registry who underwent non–stent-based BTK PAD intervention between 2006 and 2021 were included. The primary outcome was the 1-year incidence of major adverse limb events (MALEs), a composite of all-cause death, any amputation, or clinically driven repeat revascularization. A total of 566 patients underwent BTK and 494 BTK + FP interventions; 72% were men, with a mean age of 68.4 ± 10.9 years. Diabetes mellitus was more prevalent in the BTK-only group (76.5% vs 69%, p = 0.006). Mean Rutherford class was 4.2 ± 1.18; chronic limb-threatening ischemia was more frequent in the BTK group (55.3% vs 49%, p = 0.040). Moderate to severe calcification was more frequent in the BTK + FP group (21.2% vs 27.1%, p = 0.024), as was lesion length (110.6 ± 77.3 vs 135.4 ± 86.3 mm, p <0.001). Nearly 81% of lesions were treated with percutaneous transluminal angioplasty. Drug-coated balloon (1.6% vs 14%, p <0.001) and atherectomy (38% vs 58.5%, p <0.001) use was more frequent in the BTK + FP group. The rate of procedural success was higher in the BTK + FP group (86% vs 91%, p = 0.009), with amputation being the most common complication at 3.3% within 30 days after the procedure. The rates of 1-year MALE (21.2% vs 22.3%, p = 0.675) and mortality (4.6% vs 3.4%, p = 0.3) were similar between the BTK and BTK + FP groups. Nonstent treatment for BTK PAD with concomitant FP intervention leads to high procedural success and similar rates of 1-year MALE compared with isolated BTK intervention.
Condensed Abstract: The vast majority of below-the-knee (BTK) peripheral artery disease (PAD) interventions are performed with balloon angioplasty. Presence of inflow femoropopliteal PAD in patients who undergo BTK interventions can affect the outcome of the procedure. This report explores immediate procedural success and major adverse limb events at 1 year after balloon angioplasty treatment for isolated BTK PAD and in patients who underwent an additional femoropopliteal PAD intervention.

A proposed classification for uniform endoscopic description of surgical fundoplication
2014
Background
Objective assessment of postfundoplication anatomy is of utmost importance especially if reoperative intervention is being planned. There is a lack of uniformity in the description of endoscopic findings in these patients. The purpose of this study was to propose a classification for standardized endoscopic reporting of postfundoplication anatomy.
Methods
After institutional review board approval, preoperative endoscopic findings of patients who underwent reoperative intervention from 1992 to 2011 were reviewed and classified. The classification included four factors:
E
(distance of GEJ to crus),
S
(amount of gastric tissue between the GEJ and fundoplication),
F
(fundoplication configuration), and
P
(paraesophageal hernia).
Results
The endoscopic findings of 310 patients who underwent reoperative antireflux surgery were classified using the newly proposed classification model. A significant increase in the number of procedures was noted over the years. There was no change in presenting symptoms and patterns of failure over the years. The classification model was easily applicable to previous endoscopy reports. There was good symptom association with our classification model.
Discussion
An endoscopic anatomical classification is proposed for description of failed fundoplication. With this classification, we hope to fill the gap in developing a uniform classification of failed fundoplications. Further studies addressing widespread applicability and outcome analysis are needed.

Parkinson's disease is characterized by the loss of nigrostriatal dopaminergic neurons in the brain. Dopamine cannot be administered systemically because it does not cross the blood-brain barrier. Oral levodopa remains the gold standard to date. Currently, for patients who show a poor response to oral levodopa and for those who cannot take it orally, the alternate routes available are inhalation and continuous administration via intestinal and subcutaneous routes. In this report, a novel maxillofacial route was used for the first time in the world to administer levodopa to a Parkinson's patient. Furthermore, the efficacy of maxillofacial administration was compared with the oral route of administration.Parkinson's disease is characterized by the loss of nigrostriatal dopaminergic neurons in the brain.

. This paper examines empirically the unexpected compensation to the top managers of a sample of 45 firms that voluntarily changed to capitalizing interest on long‐term construction projects during the time period 1966–1974. The cash compensation to top management increased starting the year of the accounting change compared to that of top management for a firm in the same industry of similar size. Further, a comparison of the capital expenditure per dollar of sales between the sample and a pair‐matched set of firms expensing interest in the same industry suggests that the long‐term construction project was not taken up by diverting funds from routine capital expenditures. Collectively, the results are consistent with an inference that the managers were rewarded in the short term for a set of actions with expected future benefits in the long term. The accounting change, which may have facilitated the expansion, appears embedded in such a set of actions. Résumé. Les auteurs procèdent à l'examen empirique de la rétribution inattendue que reçoivent les cadres supérieurs sur un échantillon de 45 entreprises qui sont passées volontairement à la capitalisation des intérêts dans leurs projets de construction à long terme au cours de la période s'échelonnant de 1966 à 1974. La rétribution en espèces versée aux cadres supérieurs de ces entreprises a augmenté, à partir de l'année de la modification de la méthode comptable, par rapport à la rétribution versée à la haute direction entreprises de taille similaire appartenant au même secteur d'activité. En outre, une comparaison des dépenses en immobilisations par dollar de chiffre d'affaires entre les entreprises de l'échantillon et leurs homologues du même secteur d'activité ayant opté pour l'imputation des intérêts à l'exercice a révélé que les projets de construction à long terme n'étaient pas financés à même les crédits ordinairement réservés aux dépenses en immobilisations. Dans l'ensemble, les résultats confirment le raisonnement selon lequel les gestionnaires ont été rétribués à court terme pour un ensemble d'actions dont les avantages futurs prévus se manifesteront à long terme. La modification comptable, qui peut avoir facilité l'expansion, semble inscrite dans cet ensemble d'actions.
