Abstract
The present study aimed to know the effectiveness of livestock services delivered by the veterinarians working under state regional cooperative milk producers’ union (SRCMPU) and farmers views on these services. An ex-post-facto research design was adopted for the study. A total of fifteen veterinarians working under SRCMPU, Kerala, and thirty livestock farmers dependent on SRCMPU for the livestock services were selected. Data collection was done through using structured interview schedule method. The result from the study revealed that majority of the veterinarians and livestock farmers perceived curative services (60.00% and 46.66%), production services (53.33% and 63.33%), preventive services (53.34% and 56.66%), extension services (60.00% and 50.00%) and miscellaneous services (60.00% and 60.00%) as average. About satisfaction level, majority of the livestock farmers had medium level of satisfaction towards curative services (66.66%), production services (43.33%), preventive services (60.00%), extension services (50.00%) and miscellaneous services (60.00%). It is concluded from the result that there is need to improve the quality of livestock services from both veterinarians and farmers point of view. It is the need of hour to analyze and interpret the current scenario of service delivery systems of state regional cooperative milk producers’ union through assessing the constraints perceived by them in livestock service delivery.

Abstract
Background: Code selection is crucial to the accuracy and reproducibility of studies using administrative data, however a comprehensive assessment of coding trends for major cardiac diagnoses and procedures is lacking. We aimed to evaluate trends in administrative code utilization for major cardiac diagnoses and procedures, and adherence to required methodological practices in cardiac research using the National Inpatient Sample (NIS). Methods: In this observational study of 445 articles, ICD-9-CM codes corresponding to acute myocardial infarction (AMI), heart failure, atrial fibrillation, percutaneous coronary intervention, and coronary artery bypass grafting were collected and analyzed. The NIS was used to compare the number of hospitalizations between the most frequently encountered AMI case definitions. Key elements were abstracted from each article to evaluate adherence to required methodological practices. Results: Variation in code utilization was observed for each diagnosis and procedure assessed, and the number of unique case definitions published per year increased throughout the study period (P < 0.001), driven largely by the significant increase in articles per year (P < 0.001). Off-target codes were observed in 39 (8.8%) studies. Upon reintroduction into the NIS for 2008–2012, the most commonly encountered case definitions for AMI were found to yield significantly different estimates of AMI hospitalizations and hospitalization trends over time. Three hundred and ninety-nine articles (84%) did not adhere to one or more required research practices. Overall adherence was superior for publications in higher-impact journals (P = 0.002). Conclusions: Substantial variation in code selection exists for major cardiac diagnoses and procedures, and non-adherence to methodological standards is widespread. These data have important implications for the accuracy and generalizability of analyses using the NIS.

Meta-analysis of intravascular volume expansion strategies to prevent contrast-associated acute kidney injury following invasive angiography. Catheter Cardiovasc Interv 2021; 98:1120-1132. [PMID: 33185335 DOI: 10.1002/ccd.29387] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2020] [Revised: 10/19/2020] [Accepted: 10/22/2020] [Indexed: 01/16/2023]
Abstract
OBJECTIVE To perform a detailed analysis of published data regarding intravascular volume expansion to prevent contrast-associated acute kidney injury (CA-AKI) and to determine if an ideal dose of IV fluids can be recommended. BACKGROUND Administration of contrast media during invasive angiography is associated with CA-AKI. Intravascular volume expansion is the most effective intervention to prevent CA-AKI, yet evidenced based protocols are lacking. METHODS Literature review and meta-analysis of randomized controlled trials (RCT) of patients receiving IV volume expansion as prophylaxis for CA-AKI was performed. Normal saline, Lactated Ringer's and sodium bicarbonate were included. The primary outcome was incidence of CA-AKI. RESULTS 37 RCTs studying 12,166 patients were included. Mean age was 67 ± 5 years, 70% of the patients were male. 68% had chronic kidney disease, 41% diabetes, and 30% heart failure. The incidence of CA-AKI was 9.5% (95% CI: 8-12%). IV expansion versus no volume administration was associated with a lower risk of CA-AKI (RR:0.62; 95% CI: 0.49-0.77, p < .001). Intensive IV volume expansion was associated with a reduced risk of CA-AKI(RR: 0.66; 95%CI: 0.52-0.85, p < .01). The intensive IV volume expansion arm received significantly more fluids than the standard protocols: 1,574(1,123 - 1,913) ml versus 849(558-1,067) ml (p = .03) without significant difference in the duration of infusion (median of 12 vs. 17 hr, p = .1) or pulmonary edema (1.7% vs 1.3%, p = .7). CONCLUSIONS Despite high variability in protocols used, IV volume expansion is effective in preventing CA-AKI. Intensive IVF expansion (median 1.6 L over 17 hr) was associated with decreased risk of CA-AKI.

Use of iso-osmolar contrast media during endovascular revascularization is associated with a lower incidence of major adverse renal, cardiac, or limb events. Catheter Cardiovasc Interv 2021; 99:1335-1342. [PMID: 34766727 DOI: 10.1002/ccd.30006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 07/31/2021] [Accepted: 10/26/2021] [Indexed: 11/09/2022]
Abstract
OBJECTIVE We examined the association of iso-osmolar contrast media (IOCM) versus low-osmolar contrast media (LOCM) with major adverse renal, cardiovascular, or limb events in patients at high-risk of acute kidney injury (AKI) undergoing peripheral endovascular procedures. BACKGROUND Procedural characteristics including iodinated contrast type and volume have been associated with adverse renal and cardiovascular outcomes in patients undergoing angiographic interventions. METHODS Patients at high-risk of AKI, undergoing peripheral endovascular procedures were identified using the Premier Healthcare Database and separated into claudication and critical limb ischemia (CLI) cohorts. For each cohort, we compared IOCM versus LOCM for the primary endpoint of MARCE (major adverse renal or cardiovascular events) and secondary endpoints of major adverse renal events (MARE) and major adverse renal and limb events (MARLE). These outcomes were captured within the indexed hospitalization via adjusted multivariable regression analyses. RESULTS Two procedure-based cohorts of high-risk patients were formed: claudication (N = 11,976) and CLI (N = 8713). Use of IOCM was associated with a significant absolute risk reduction (ARR) of 2.2% (p < 0.0001) for MARCE overall and in each cohort (claudication, 1.8%, p = 0.0070; CLI, 2.7%, p = 0.0054). The incidence of MARE and MARLE in the overall cohort was also lower with the use of IOCM: MARE (ARR = 1.4%, p = 0.0072) and MARLE (ARR = 2.0%, p = 0.0043). CONCLUSIONS Using IOCM versus LOCM in patients at high-risk of adverse renal events undergoing peripheral endovascular procedures was independently associated with lower risk of MARCE, MARE, and MARLE.

Abstract
OBJECTIVES The authors analyzed data from the NCDR (National Cardiovascular Data Registry) PVI Registry and defined acute kidney injury (AKI) as increased creatinine of ≥0.3 mg/dl or 50%, or a new requirement for dialysis after PVI. BACKGROUND AKI is an important and potentially modifiable complication of peripheral vascular intervention (PVI). The incidence, predictors, and outcomes of AKI after PVI are incompletely characterized. METHODS A hierarchical logistic regression risk model using pre-procedural characteristics associated with AKI was developed, followed by bootstrap validation. The model was validated with data submitted after model creation. An integer scoring system was developed to predict AKI after PVI. RESULTS Among 10,006 procedures, the average age of patients was 69 years, 58% were male, and 52% had diabetes. AKI occurred in 737 (7.4%) and was associated with increased in-hospital mortality (7.1% vs. 0.7%). Reduced glomerular filtration rate, hypertension, diabetes, prior heart failure, critical or acute limb ischemia, and pre-procedural hemoglobin were independently associated with AKI. The model to predict AKI showed good discrimination (optimism corrected c-statistic = 0.68) and calibration (corrected slope = 0.97, intercept of -0.07). The integer point system could be incorporated into a useful clinical tool because it discriminates risk for AKI with scores ≤4 and ≥12 corresponding to the lower and upper 20% of risk, respectively. CONCLUSIONS AKI is not rare after PVI and is associated with in-hospital mortality. The NCDR PVI AKI risk model, including the integer scoring system, may prospectively estimate AKI risk and aid in deployment of strategies designed to reduce risk of AKI after PVI.

Abstract
OBJECTIVE The purpose of this analysis was to examine the association of iso-osmolar contrast media (IOCM) vs low-osmolar contrast media (LOCM) with major adverse renal or cardiovascular events (MARCE) in patients at high risk of acute kidney injury (AKI), undergoing endovascular abdominal aortic aneurysm repair (EVAR). METHODS Patients at high risk of AKI (defined as age ≥75 years, or one or more of the following comorbidities: diabetes, anemia, chronic kidney disease (CKD stages 1-4) or congestive heart failure), undergoing EVAR from September 2012 to June 2018 were identified using the Premier Hospital Database. We compared the primary endpoint of MARCE (composite of AKI, AKI requiring dialysis, acute myocardial infarction [AMI], stroke/transient ischemic attack [TIA], and death) with IOCM vs LOCM via adjusted multivariable regression analyses. RESULTS Among 15,777 high-risk patients undergoing EVAR, the occurrence of in-hospital MARCE was 6.8%, including renal events (4.5%), AMI (0.8%), stroke/TIA (0.4%), and death (1.9%), IOCM was used in 7360 patients (47%). Multivariable modeling found IOCM was associated with 1.8% (95% confidence interval [CI], 0.4-3.3; P=.01) lower absolute risk for MARCE (23.9% relative risk reduction; 95% CI, 5.2%-44.2%). CONCLUSIONS Use of IOCM vs LOCM in patients at high risk of AKI undergoing EVAR procedures was associated with a lower risk of MARCE. As prevention of AKI or cardiovascular events after EVAR procedures may lead to reduced morbidity and mortality, this finding may have important clinical implications and should be confirmed through randomized controlled clinical studies.

Abstract
Acute kidney injury (AKI) is an ominous predictor of mortality in cardiogenic shock. The present review examines the pathophysiology of AKI in cardiogenic shock (CS), summarizes the pertinent literature including the diagnostic criteria/definitions for AKI and possible role of biomarkers, and identifies risk factors and possible therapeutic interventions for AKI in CS. Our review finds that AKI is common in patients with CS and is associated with increased morbidity and mortality. Urinary biomarkers of renal tubular injury appear more sensitive for detection of AKI but have yet to be incorporated into daily practice. Emerging data would suggest vasopressor choices, mechanical circulatory support, and renal replacement therapy may have important therapeutic roles in the management of CS.

Abstract
BACKGROUND The outcome of endovascular intervention (EVI) compared vs. surgical revascularization in patients with peripheral artery disease (PAD) due to chronic total occlusion (CTO) is unknown. METHODS Using the National Inpatient Sample database between 2007 and 2014, we identified all PAD patients with CTO who had limb revascularization. Multivariate analysis was performed to estimate the odds of in-hospital mortality and adverse outcomes between both groups. RESULTS A total of 168,420 patients who had peripheral CTO and underwent limb revascularization were identified. 99,279 underwent EVI, and 69,141 underwent surgical revascularization. The patients who underwent EVI were younger, more likely to be women and African American, and less likely to be white (p < 0.001 for all). EVI was associated with lower in-hospital mortality (1.2% vs 1.7%, adjusted odds ratio [aOR]: 0.54; 95% confidence interval [CI] 0.50-0.59). The EVI group had higher vascular complications, major bleeding, acute kidney injury (AKI), and major amputation compared with surgical revascularization. A subgroup analysis on patients with critical limb ischemia showed lower mortality in the EVI group (1.4% vs. 1.9, aOR 0.56; 95% CI 0.50-0.63). Although there was no difference in the incidence of AKI or major amputation between the two groups, the EVI group had higher vascular complication rates and major bleeding events. CONCLUSION EVI in PAD with CTO is associated with lower in-hospital mortality, likely due to the procedure's less-invasive nature; however, it is associated with higher postprocedural complications likely due to the CTO's complexity.

Personal Protective Equipment and Donning and Doffing Techniques in the Cardiac Catheterization Laboratory During the COVID-19 Pandemic: Insights From an Internet Search for Protocols. Front Cardiovasc Med 2021; 8:652298.

Abstract
Background: Due to the ongoing coronavirus disease 2019 (COVID-19) pandemic, a need for precise donning and doffing protocols for personal protective equipment (PPE) among healthcare infrastructures is paramount. Procedures involving the cardiac catheterization laboratory (CCL) are routinely non-aerosolizing but have the potential for rapid patient deterioration, creating the need for aerosolizing generating procedures. Multiple societal and governmental guidelines on the use of PPE during medical procedures are available on Internet websites; however, there is limited literature available in peer-reviewed formats in this context. This study aims to provide an overview of current PPE donning and doffing protocols specific to the catheterization laboratory. Methods: A series of internet searches regarding donning and doffing of PPE in the CCL including published articles and internet protocols were compiled and compared using Pubmed.gov, Google.com, www.twitter.com, and www.youtube.com. Results: Most institutions used N95 masks, shoe covers, at least one head covering, face shield or goggles, two pairs of gloves, and inner and outer gowns. Doffing variation was greater than donning. Doffing has the potential to contaminate the healthcare worker (HCW), and therefore, this step of PPE management requires further study. Common steps in temporal priority included cleaning of gloved hands, removal of outer (or only) gown, removal of outer gloves, repeat gloved hand cleaning, removal of facial PPE last, and a final non-gloved hand cleaning. Conclusions: This analysis provides a summary of commonly used practices that may be considered when designing CCL-specific PPE protocols. Analysis of consistent steps from the literature led the authors to formulate a suggested protocol for CCL HCWs when performing procedures on patients with confirmed or suspected/unknown COVID-19.

Abstract
Objective To determine patients’ willingness to undergo elective orthopaedic surgery during the COVID-19 pandemic. Method 4 groups of patients were chosen based on type of surgery. A telephone survey was conducted, including questions on diagnosis, symptom duration, pain severity, co-morbidities, anxiety levels for COVID-19 and surgery. Patients were given the conditions for surgery and asked whether they would undergo surgery, have the operation carried out by another consultant and any factors that would increase their confidence. Results Of 200 patients, 156 participated (78%). 78.2% were willing to undergo surgery. There was a statistically significant difference in willingness between age groups 40-49 (100%) and 80 + (58.3%). Differences in willingness between surgery types, BOA risk class, sex, symptom duration and pain scores, were not statistically significant. Patients unwilling to undergo surgery reported statistically higher anxiety scores for health (4.39) and surgery (4.62) compared to the willing group (2.89 and 2.71 respectively). Patients’ main concern was contracting COVID (35.2%). Conclusions Our study demonstrated that the majority of patients were willing to undergo surgery. This can be used to inform strategies for resuming elective surgeries. It has also highlighted several areas in patient perception that warrant further investigation and the importance of enhanced consent on the specific risks.

Abstract
OBJECTIVE There is a paucity of data regarding six-month readmissions in critical limb ischemia patients and the influence of management strategy during index-admission [endovascular, surgical, hybrid procedure, medical therapy, and amputation]. We aimed to investigate the incidence, predictors, and impact of management strategies on six-month readmission in patients with critical limb ischemia. METHODS A secondary analysis of the Nationwide Readmissions Database (2016-2017) was conducted. Propensity score matching was performed for subgroup analysis. RESULTS We identified 50,058 patients with primary diagnosis of critical limb ischemia. Six-month all-cause and critical limb ischemia-related readmission rate was 52.36% and 10.86%, respectively. The risk of all-cause readmission was lower with amputation but was similar among other subgroups. Patients receiving surgical [HR 0.62, CI(0.48-0.79), p < 0.001] and hybrid procedure [HR 0.65 (0.46-0.93), p = 0.02] had lower risk of unplanned critical limb ischemia-related readmission compared to endovascular, though the risk of unplanned revascularization/amputation during readmission was similar between the three strategies. The risk of non-critical limb ischemia-related readmission was higher with surgical [HR 1.13, CI(1.04-1.23), p = 0.003] and hybrid procedure [HR 1.17, CI(1.08-1.28), p < 0.001], driven by increased procedure-related/wound complications. Eventhough endovascular patients were older with more severe critical limb ischemia presentation, a lower proportion received home-health or placement upon discharge from index-admission. This could account for higher readmission without higher repeat revascularization in endovascular group. CONCLUSION The risk of critical limb ischemia and non-critical limb ischemia-related readmission differ according to the management strategy. Significant differences in discharge disposition exist depending on revascularization strategy. Study findings identify opportunities for reducing readmissions by focusing on nonprocedural aspects like wound-care, discharge planning and placement.

Abstract
The relative safety and efficacy of aspirin versus dual antiplatelet therapy (DAPT; aspirin+clopidogrel) in patients who underwent transcatheter aortic valve implantation (TAVI) and did not have a long-term indication for oral anticoagulation remains controversial. Digital databases were searched to identify relevant articles. The major safety end point was bleeding, while the efficacy end points included after-TAVI ischemic and thrombotic events. Data were analyzed using a random effect model to calculate the pooled unadjusted odds ratio (OR) for dichotomous outcomes. Eleven studies comprising 4805 patients (aspirin 2258, DAPT 2547) were included in the quantitative analysis. Patients receiving aspirin-alone had significantly lower odds of all cause bleeding (OR 0.41, 95% CI 0.29 to .057, p <0.00001), major vascular bleeding (OR 0.51, 95% CI 0.34 to 0.77, p = 0.001), Valve Academic Research Consortium 2 (VARC-2) major bleeding (OR 0.50, 95% CI 0.30 to 0.83 p = 0.008), VARC-2 minor bleeding (OR 0.55, 95% CI 0.31 to 0.97, p = 0.04), transfusion requirement (OR 0.39, 95%CI 0.15 to 0.0.98, p = 0.05) and major vascular complications (OR0.41, 95% CI 0.26 to 0.66, p = 0.0002) compared with after-TAVI patients receiving both aspirin and clopidogrel. These was no significant difference in the odds of VARC-2 life threatening bleeding (OR 0.52, 95% CI 0.25 to 1.07, p = 0.08), prosthetic valve thrombosis (OR 1.17, 95% CI 0.22 to 6.30, p = 0.85), cardiac tamponade (OR 0.77, 95% CI 0.20 to 2.98, p = 0.70), conversion to open procedure (OR 1.99, 95 % CI 0.42 to 9.44, p = 0.39), MI (OR 0.79 95% CI 0.38 to 1.64, p = 0.52), transient ischemic attack (TIA) (OR 0.89, 95% CI 0.12 to 6.44, p = 0.91), major stroke (OR 0.68 95 % CI 0.43 to 1.08, p = 0.10), disabling stroke (0R 1.01, 95% CI 0.41 to 2.48, p = 0.99), cardiovascular mortality (OR 0.81 95% CI 0.38 to 1.74, p = 0.59) and all-cause mortality (OR 0.86, 95% CI 0.63 to 1.16, p = 0.31) between the 2 groups. In conclusion, after-TAVI patients who received aspirin alone had lower bleeding events with no significant differences in mortality and stroke rate compared with those who received DAPT.

Abstract
As the severe acute respiratory syndrome coronavirus 2 virus pandemic continues to grow globally, an association is apparent between patients with underlying cardiovascular disease comorbidities and the risk of developing severe COVID-19. Furthermore, there are potential cardiac manifestations of severe acute respiratory syndrome coronavirus 2 including myocyte injury, ventricular dysfunction, coagulopathy, and electrophysiologic abnormalities. Balancing management of the infection and treatment of underlying cardiovascular disease requires further study. Addressing the increasing reports of health care worker exposure and deaths remains paramount. This review summarizes the most contemporary literature on the relationship of the cardiovascular system and COVID-19 and society statements with relevance to protection of health care workers, and provides illustrative case reports in this context.

Abstract
OBJECTIVES This study sought to assess periprocedural bleeding complications in lower-extremity peripheral vascular interventions (PVIs). BACKGROUND Few studies have examined the incidence, predictors, or outcomes of periprocedural bleeding after lower-extremity PVI. METHODS The study examined patients undergoing PVI at 76 hospitals in the National Cardiovascular Data Registry PVI registry from 2014 to 2016. Post-PVI major bleeding was defined as any overt bleeding with a hemoglobin (Hb) drop of ≥3 g/dl, any Hb decline of ≥4 g/dl, or blood transfusion in patients with pre-procedure Hb >8 g/dl within 72 h of their procedure. Hierarchical multivariable logistic regression was used to identify factors independently associated with post-PVI bleeding. The study also examined adjusted in-hospital mortality among patients with or without major bleeding complications. RESULTS Among 18,289 PVI procedures, major bleeding occurred in 744 (4.10%). Patient characteristics independently associated with bleeding included age, female sex, heart failure, pre-procedural hemoglobin <12 g/dl, nonelective PVI, and critical limb ischemia on presentation. Procedural characteristics associated with bleeding included nonfemoral vascular access, use of thrombolytic therapy, PVI of the aortoiliac segment, and multilesion interventions, whereas use of closure devices was associated with less bleeding. All-cause in-hospital mortality was higher in patients who experienced bleeding than in those who did not (6.60% vs. 0.30%; p < 0.001; adjusted hazard ratio: 10.9; 95% confidence interval: 6.9 to 17.0). CONCLUSIONS Major bleeding occurred in 4.10% of lower-extremity PVI procedures and was associated with several patient and procedural characteristics, as well as in-hospital mortality. These insights can be incorporated into strategies to reduce periprocedural bleeding after PVI.

Abstract
Contrast-associated acute kidney injury, resulting from the use of iodinated contrast media, is a well-known adverse event following endovascular procedures and is associated with poor prognosis when it happens. There is an abundance of literature studying acute kidney injury following percutaneous coronary interventions, with very few studies done in the setting of percutaneous peripheral intervention. Although both percutaneous coronary intervention and percutaneous peripheral intervention utilize iodinated contrast media, several differences exist that can affect the incidence and management of contrast-associated acute kidney injury. This article aims to review what we currently know about contrast-associated acute kidney injury and available prevention strategies, specifically following percutaneous peripheral interventions.

Multiple anthelmintic resistance in gastrointestinal nematodes of Caprines on Mountain Research Centre for Sheep and Goat at Kashmir Valley, India. Parasite Epidemiol Control 2020; 11:e00163.

Abstract
The study was conducted to evaluate the status of anthelmintic resistance in Gastro-Intestinal Nematodes (GINs) of goats at an organized farm located in Kashmir, as there is no report of resistance against these parasites of goats from this temperate region, although it has been reported worldwide including India. Caprines reared at this farm exhibited reduced efficacy to multiple anthelmintics following treatments with Fenbendazole (FBZ), Closantel and Ivermectin (IVM) in Faecal Egg Count Reduction Test (FECRT). The results suggested that the overall efficacy was highest for IVM at 83.5% and 90.0% on 7th and 14th day post-treatment, respectively and least for FBZ at 44.3% and 62.5%, respectively, whereas the corresponding figures for closantel were 68.3% and 86.2%, respectively. The pre-treatment faecal culture revealed Haemonchus contortus, Teladorsagia circumcincta and Trichostrongylus colubriformis as predominant strongyles, however, in post-treatment samples, only H. contortus was observed. Further, the infective larvae were subjected to Allele specific PCR (AS-PCR) for accurate diagnosis of BZ resistance. The AS-PCR revealed 52% of H. contortus were homozygous resistant (rr) and 17% were heterozygous (rS) on day “0” before treatment and 100% homozygous resistant (rr) on 7th day post treatment. In both T. colubriformis and T. circumcincta, 100% population was homozygous susceptible (SS) at day “0” before treatment. The overall frequency of resistant (r) allele for H. contortus was 60.5% and for susceptible allele (s) was 39.5%. For T. colubriformis and T. circumcincta the frequency of susceptible allele (s) was 100%. The survey indicated that the GINs of goats on the farm have developed multiple anthelmintic resistance to FBZ, closantel and IVM and the condition is alarming in the farm. Moreover surveillance studies about status of anthelmintic resistance in other farms (Govternment as well as Private) of Kashmir valley should be carried out at large scale to develop effective and sustainable control strategies against GI Nematodes.

Abstract
Since the first peripheral endovascular intervention (PVI) in 1964, the procedure's technical aspects and indications have advanced significantly. Today, endovascular procedures span the spectrum of presentations from acute limb ischemia to critical limb ischemia and symptomatic limiting claudication. Goals of PVI remain restoring limb perfusion, minimizing rates of amputation and mortality, and sparing the need for the high-risk bypass surgery. Unfortunately, there are no large randomized controlled trials that address the optimal approach to peripheral arterial disease revascularization in chronic kidney disease (CKD) patients.

Abstract
BACKGROUND Acute kidney injury (AKI) following transcatheter aortic valve replacement (TAVR) is a known complication. The prospective validation of various AKI definitions and estimated baseline renal function equations in the context of TAVR remains an ongoing area of research. This study examined the Valve Academic Research Consortium (VARC) 1 and 2 criteria for AKI, and impact of three estimated glomerular filtration rate (eGFR) equations (CKD-EPI, MDRD, and Cockcroft-Gault) on AKI incidence in TAVR patients. METHODS Retrospective review of 120 consecutive TAVR procedures over a 4-year period was performed. AKI, including stage, was defined using the VARC 1 and VARC 2 criteria. Univariate and multivariate analyses were performed for association between AKI and known patient, hemodynamic, and procedural variables. Further logistic regression, stepwise logistic regression, and association plots were performed for the three different eGFR calculations. RESULTS AKI occurred in 22% of VARC 1 patients and 23% of VARC 2 patients. On multivariate analysis, baseline eGFR was predictive of stage 1 AKI by CKD-EPI classification (VARC 1: odds ratio [OR], 0.93; 95% confidence interval [CI], 0.88-0.99; P=.02; VARC 2: OR, 0.93; 95% CI, 0.87-0.99; P=.03) and MDRD (OR, 0.93; 95% CI, 0.88-0.99; P=.03). Non-transfemoral approach was predictive of stage 1 AKI by VARC 2 (OR, 33.33; 95% CI, 1.6-696.41; P=.02). CONCLUSIONS The risk factor associations for AKI post TAVR vary by definitions used. Decreased GFR at baseline by both MDRD and CKD-EPI and non-transfemoral approach were associated with an increased risk of AKI post TAVR.

Abstract
BACKGROUND Despite a range of devices, medical interventions, and revascularization techniques utilized in cardiogenic shock (CS), there is a lack of evidence guiding management. We sought to characterize the contemporary trials through utilization of the ClinicalTrials.gov database. METHODS We investigated all phase II-IV interventional trials in the ClinicalTrials.gov database through June 29, 2019 that enrolled patients with CS. Published trials investigating medical interventions were evaluated for methodological quality using the Jadad scoring system. RESULTS The initial query yielded 28 registered studies, of which 28 directly studied CS through whole or subgroup analyses. Of these, five were withdrawn or terminated, while 13 were recruiting, not yet recruiting, or were of unknown recruitment status. The remaining 10 were published and had a median patient size of 69 patients and a median site size of 6. Of the published studies, all-cause mortality was the most common primary endpoint (60%), including composite endpoints that included mortality. The remaining endpoints examined surrogate hemodynamic parameters of cardiac function through echocardiography. The mean Jadad score of the published trials investigating pharmacological therapies was 2.42. Of the trials investigating device therapies or revascularization methods, all were randomized, parallel-arm studies that were open label. CONCLUSIONS Modern trials vary from single center to multicenter and are small in size. The primary endpoints were clinical, focusing on mortality and restoration of cardiac output or cardiac index. Methodological quality varies in the trials focused on pharmacologic therapy. Trials with devices or revascularization do not employ blinding, but do employ randomization.
