RESUMEN
BACKGROUND: We investigated the rates of acute kidney injury (AKI) post robot-assisted laparoscopic prostatectomy (RALP). METHODS: A comprehensive search was conducted to identify studies that reported the rates of AKI post-RALP. A random effects model was used, and the pooled rates of AKI were calculated. RESULTS: We identified 10 studies with 60,937 patients to be included. The mean age was 65.1 years. The mean anaesthesia time was 234.3 min (95% CI: 177.8-290.9). The mean operation time was 212.2 min (95% CI: 188.7-235.6). The mean estimated blood loss was 314.1 mL (95% CI: 153-475.3). The mean intraoperative IV fluids administered were 1985 mL (95% CI: 1516.3-2453.7). The pooled rate of AKI post RALP was 7.2% (95% CI 19-23.9). CONCLUSIONS: The rates of AKI after RALP are significant. Further studies are needed to detect the risk factors for AKI and to determine the rates of chronic kidney disease post-RALP.

In this systematic review and meta-analysis, we explored the utilization of cardiac magnetic resonance imaging (CMR) to detect fibrotic changes secondary to uremic cardiomyopathy during the early stages of chronic kidney disease (CKD) and in patients with end-stage kidney disease (ESKD). Uremic myocardial fibrosis can lead to arrhythmia and heart failure, and it is important to detect these changes. CMR offers a noninvasive way to characterize the severity of cardiac remodeling. A comprehensive search of multiple electronic databases was conducted. Studies were divided according to scanner field strength (1.5 or 3 Tesla). The random effects model was used to calculate the pooled mean, 95% confidence interval (CI), standard error, and standardized mean difference (SMD). The I2 statistic was used to assess the heterogeneity between study-specific estimates. The search retrieved 779 studies. From these, 20 studies met the inclusion criteria and had 642 CKD patients (mean age of 56.8 years; 65.2% males; mean estimated glomerular filtration rate (eGFR) of 33 mL/min/1.73 m2) and 658 ESKD patients on dialysis (mean age of 55.6 years; 63.3% males; mean dialysis duration of 3.47 years). CKD patients had an increased left ventricular mass index (LVMi) compared to controls, with an SMD of 0.37 (95% CI: 0.20-0.54; I2 0%; p-value <0.05). ESKD patients also had increased LVMi compared to controls, SMD 0.88 (95% CI: 0.35-1.41; I2 79.1%; p-value 0.001). Myocardial fibrosis assessment using T1 mapping showed elevated values; the SMD of native septal T1 values between CKD and controls was 1.099 (95% CI: 0.73-1.46; I2 33.6%; p-value <0.05), and the SMD of native septal T1 values between ESKD patients and controls was 1.12 (95% CI: 0.85-1.38; I2 33.69%; p-value <0.05). In conclusion, patients with CKD and ESKD with preserved left ventricular ejection fraction (LVEF) have higher LVMi and T1 values, indicating increased mass and fibrosis. T1 mapping can be used for the early detection of cardiomyopathy and as a risk stratification tool. Large, randomized trials are needed to confirm these findings and determine the effect of long-term dialysis on cardiac fibrosis.
RESUMEN
Alcohol septal ablation (ASA) is a well-established procedure for septal reduction therapy in patients with obstructive hypertrophic cardiomyopathy, significant at rest or provocable outflow tract gradients, and medically refractory symptoms. This percutaneous approach to relief of obstruction and eventual cardiac remodeling involves the infusion of a small quantity of ethanol into an appropriately targeted septal artery that is feeding the basal septum to create an iatrogenic and controlled focal infarction. Early akinesia is followed by subsequent thinning and remodeling, which widens the outflow tract, reducing or eliminating the obstruction. Historically, the use of ASA was reserved primarily for high-risk surgical candidates; however, more contemporary data suggest similar outcomes in the short-term and long-term safety of the procedure and overall effectiveness in relieving obstructive symptoms when it is performed in broader populations at experienced centers. Therefore, the current guidelines published in 2020 support ASA as a class 1 indication, similar to its open-heart surgical counterpart, surgical myectomy, when no concomitant significant coronary or valve surgical indication exists. This article summarizes contemporary management of patients with hypertrophic cardiomyopathy who were selected for ASA and details procedural methods and outcomes.

Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), later renamed coronavirus disease 2019 (COVID-19), was first identified in Wuhan, China, in early December 2019. Initially, the China office of the World Health Organization was informed of numerous cases of pneumonia of unidentified etiology in Wuhan, Hubei Province at the end of 2019. This would subsequently result in a global pandemic with millions of confirmed cases of COVID-19 and millions of deaths reported to the WHO. We have analyzed most of the data published since the beginning of the pandemic to compile this comprehensive review of SARS-CoV-2. We looked at the core ideas, such as the etiology, epidemiology, pathogenesis, clinical symptoms, diagnostics, histopathologic findings, consequences, therapies, and vaccines. We have also included the long-term effects and myths associated with some therapeutics of COVID-19. This study presents a comprehensive assessment of the SARS-CoV-2 virology, vaccines, medicines, and significant variants identified during the course of the pandemic. Our review article is intended to provide medical practitioners with a better understanding of the fundamental sciences, clinical treatment, and prevention of COVID-19. As of May 2023, this paper contains the most recent data made accessible.
RESUMEN
Background: Acute ischemic stroke (AIS) following left ventricular assist device (LVAD) implantation is a serious complication associated with device morbidity. AIS development following LVAD placement typically presents between 6- and 24-months post implantation.Case/Results: We report a case of a 67-year-old male who initially presented with reduced ejection fraction and severe coronary vessel disease. Following coronary artery bypass graft surgery, the patient remained in a low output state necessitating placement of an LVAD device. Approximately 4.5 hours following LVAD implantation, a severe acute decrease in mental status revealed new development of ischemic stroke of the basilar artery, which was successfully treated in one pass with catheter endovascular thrombectomy.Conclusion: While embolic stroke management in these cases remains difficult as patients are usually anticoagulated, our case demonstrates the utilization of endovascular thrombectomy as a viable therapeutic option in the setting of an uncommon occurrence of embolic stroke in the hours following LVAD implantation.
RESUMEN
Gonorrhea is a sexually transmitted infection caused by gram-negative diplococci, Neisseria gonorrhoeae. Disseminated gonorrhea is diagnosed infrequently, partly due to low suspicion at the time of presentation, and at times, due to overlapping symptoms associated with non-infectious conditions like systemic lupus erythematosus (SLE). In this article, we present a 42-year-old sexually active female with knee pain and swelling, fever, and rash. Knee aspirate showed the presence of monosodium urate crystals, and the synovial culture grew gram-negative diplococci, requiring multiple joint washouts. The urine nucleic acid amplification test (NAAT) was indeterminate. She was treated with high-dose intravenous ceftriaxone for one week post-joint washout with rapid improvement in her condition and resolution of the rash.
RESUMEN
The 2021 Percutaneous Coronary Intervention guidelines completed by American College of Cardiology/American Heart Association/Society for Cardiovascular Angiography and Interventions provide a set of guidelines regarding revascularization strategies. With emphasis on equity of care, multidisciplinary heart team use, revascularization for acute coronary syndrome, and stable ischemic heart disease, the guidelines create a thorough framework with recommendations regarding therapeutic strategies. In this comprehensive review, our aim is to summarize the 2021 revascularization guidelines and analyze key points regarding each recommendation.
RESUMEN
In the setting of an acute pulmonary embolism (PE), there is often an assumed association between a saddle PE (SPE) and increased clinical severity. We aimed to determine the magnitude of SPE proximal pulmonary artery (PA) flow obstruction and its impact on right ventricular (RV) function in the setting of acute PE in a single-center series. From 2005 to 2022, patients with acute PE presenting with acute RV dysfunction requiring intervention were classified as SPE and non-SPE based on presenting computed tomography (CT) scans. SPE flow obstruction was determined by the ratio of the orthogonal cross-sectional surface area measurements of clot and native PA at the location of maximum clot burden in the right PA and left PA. Presenting RV function based on clinical and imaging parameters (CT and transthoracic echocardiography) were compared between SPE and non-SPE cohorts. A total of 174 patients were identified (SPE 92 [52.9%] and non-SPE 82 [47.1%]). Demographics and co-morbidities were similar. In patients with SPE, there was a mean 25.9% total flow obstruction (right PA 26.9% and left PA 25.5%). Non-SPE had greater clinical RV dysfunction on presentation as reflected by more high-risk PE (43.9% vs 26.1%, p = 0.01), need for venoarterial extracorporeal membrane oxygenation (21.9% vs 10.9%, p = 0.05), and more preoperative cardiopulmonary resuscitation (16.7% vs 7.8%, p = 0.08). RV:left ventricular ratio (CT and transthoracic echocardiography) and RV fractional area change were statistically similar between groups. In-hospital mortality was statistically similar between cohorts (4.9% non-SPE vs 2.1% SPE, p = 0.32). In conclusion, in a single-center series of patients with acute PE with RV dysfunction, SPE did not cause proximal flow-limiting obstruction. Non-SPE was associated with more clinical RV dysfunction than SPE. Thus, it should not be assumed that a non-SPE is a marker of patient stability.

Severe mitral regurgitation (MR) is an important cause of acute heart failure and significant contributor to morbidity and mortality. Mechanical circulatory support (MCS) devices such as Impella are readily used to hemodynamically stabilize patients with cardiogenic shock (CS) secondary to this valvular pathology. Impella can also be combined with VA-ECMO to an "ECPELLA" configuration if further escalation of hemodynamic support is needed. We report a case of a 57-year-old female who presented with CS secondary to a perforated anterior mitral valve leaflet and non-ischemic cardiomyopathy that did not stabilize with initial choice of Impella 5.5. She required further escalation from axillary Impella 5.5 to the combined ECPELLA configuration, which allowed hemodynamic stabilization and ultimately a successful high-risk isolated mitral valve replacement. Despite adequate Impella flow, escalation to a combined MCS configuration, such as ECPELLA, may need to be considered upfront for acute valvular insufficiency in the setting of pre-existing cardiomyopathy.
RESUMEN
Anticoagulation and antiplatelet therapy are individually mainstays of treatment for multiple cardiovascular conditions. Antiplatelet therapy, most commonly with dual agents, is vital in the setting of coronary artery disease with acute coronary syndrome requiring percutaneous coronary intervention to prevent in-stent complications. A multitude of cardiovascular conditions with increased thromboembolic risk also require anticoagulation, including atrial fibrillation, venous or arterial thrombosis, and prosthetic heart valves to name a few. There is often an overlap in comorbidities as our patient population ages and becomes more complex, frequently necessitating a combination of both anticoagulation and antiplatelet agents, known as "triple therapy". To reduce or treat thromboembolic disease states as well as reduce platelet aggregation for coronary stent protection, many patients are placed at an increased bleeding risk without compelling evidence of reduction in major adverse cardiac events. With this comprehensive review of the existing literature, we aim to analyse different strategies and durations of triple therapy medication regimens.
RESUMEN
Histoplasmosisis a common mycosis in North and Central America caused by Histoplasma capsulatum. Affected patients typically remain asymptomatic. However, in some individuals, histoplasmosis can present as a severe illness, usually occurring in patients with underlying risk factors such as the immunocompromised (e.g., acquired immunodeficiency syndrome (AIDS), treatment with immunosuppressive agents), and the elderly without underlying immunocompromised conditions. Here, we present a case of disseminated histoplasmosis diagnosed as an incidental finding on bone marrow biopsy while treating a hospitalized patient for hemophagocytic lymphohistiocytosis. The patient presented with weight loss, anorexia, fatigue, and generalized weakness. The patient was successfully treated with amphotericin B and eventually transitioned to itraconazole.
RESUMEN
Vegetarianism in any of its various forms, particularly veganism, has been increasing in popularity over the past few years, especially among the young population in the United States. While several studies have shown that a vegan diet (VD) decreases the risk of cardiometabolic diseases, such as cardiovascular disease, type 2 diabetes mellitus, obesity, and non-alcoholic fatty liver disease, veganism has been associated with adverse health outcomes, namely, nervous, skeletal, and immune system impairments, hematological disorders, as well as mental health problems due to the potential for micro and macronutrient deficits. The goal of this review article is to discuss the current literature on the impact and long-term consequences of veganism on vulnerable populations, including children, adolescents, pregnant and breastfeeding women, and fetal outcomes in strict vegan mothers. It also focuses on the many deficiencies of the vegan diet, especially vitamin B12, and the related increased risk of malignancies.
RESUMEN
Nonalcoholic fatty liver disease (NAFLD) is a disease process that is gaining increasing recognition. The global prevalence of NAFLD is increasing in parallel with growing rates of risk factors for NAFLD such as hypertension, obesity, diabetes, and metabolic syndrome. NAFLD has been referred to as a risk factor for cardiovascular disease (CVD). As CVD is the leading cause of morbidity and mortality worldwide, there are constant efforts to describe and alleviate its risk factors. Although there is conflicting data supporting NAFLD as a causative or associative factor for CVD, NAFLD has been shown to be associated with structural, electrical, and atherosclerotic disease processes of the heart. Shared risk factors and pathophysiologic mechanisms between NAFLD and CVD warrant further explication. Pathologic mechanisms such as endothelial dysfunction, oxidative stress, insulin resistance, genetic underpinnings, and gut microbiota dysregulation have been described in both CVD and NAFLD. The mainstay of treatment for NAFLD is lifestyle intervention including physical exercise and hypocaloric intake in addition to bariatric surgery. Investigations into various therapeutic targets to alleviate hepatic steatosis and fibrosis by way of maintaining the balance between lipid synthesis and breakdown. A major obstacle preventing the success of many pharmacologic approaches has been the effects of these medications on CVD risk. The future of pharmacologic treatment of NAFLD is promising as effective medications with limited CVD harm are being investigated.

RESUMEN
Percutaneous catheter-directed interventions for pulmonary embolism is a rapidly evolving field. We present the first case report of simultaneous intravascular ultrasound (IVUS) use during transcatheter pulmonary embolectomy. Real-time IVUS guidance offers the advantage of better clot visualization and precise suction catheter localization while minimizing contrast medium exposure and wire exchanges. (Level of Difficulty: Advanced.).
RESUMEN
INTRODUCTION: Oral and dental health form an integral part of complete well being of an individual and society at large. Promoting oral health and societal progression go hand in hand. AIM: To investigate dentists' attitudes about pain and infection control while treating children and adolescents by assessing their recommendations of pre- and postoperative analgesics and antibiotics, and use of local anesthesia (LA) for definitive treatment in different clinical scenarios. MATERIALS AND METHOD: A total of 400 dentists, both general dental practitioners (GDPS) as well as specialist dentists, were surveyed over a period of 2 months by using a pre-tested close-ended questionnaire. The data was statistically analyzed using Pearson's Chi-square test and backward logistic regression analysis for analysis of categorical variables and independent variables, respectively. Level of significance was set at 5%. RESULTS: It was found that there was a gross overuse of antibiotics and analgesics and under use of LA by GDPs compared to specialist dentists. Postoperative antibiotics and analgesics were used more commonly than preoperative antibiotics and analgesics. These strategies were used more often in permanent teeth than primary teeth except the use of LA, which was used with equal frequency in both primary as well as permanent dentition. CONCLUSION: Dependence on antibiotics and analgesics for achieving pain and infection control in children has to be minimized and focus has to be shifted on judicious definitive treatment involving use of LA, aseptic techniques, and behavior management techniques.
RESUMEN
Background: Given that nearly a quarter of the US physician workforce are international medical graduates (IMGs), many of whom remain on temporary work visas for prolonged periods due to processing delays, the pandemic has posed unique challenges to these frontline workers and has arbitrarily limited our physician workforce. Methods: This is cross-sectional survey data obtained from IMGs on temporary work visas pertaining to their role in healthcare, impact of visa-related restrictions on their professional and personal lives was sent to the participants. Results: A total of 2630 IMGs responded to the survey. Most of the respondents (1493, 56.8%) were physicians in active practice, with Internal Medicine (1684, 65.7%) being the predominant specialty encountered. 64.1% were practicing in Medically Underserved Areas (MUA) or Health Professional Shortage Areas (HPSA), with 45.6% practicing in a rural area. Nearly 89% of respondents had been involved with direct care of COVID-19 patients, with 63.7% assuming administrative responsibilities for COVID-19 preparedness. 261 physicians (11.5%) were subject to quarantine, while 28 (1.2%) reported a confirmed COVID-19 infection. 93% physicians expressed inability to serve in COVID-19 surge areas due to visa-related restrictions, while 57% had been approached by recruiters due to staffing shortages. 72% physicians reported that their families would be at risk for deportation in case of their disability or death. Most respondents (98.8%) felt that permanent resident status would help alleviate the above concerns. Conclusion: A significant proportion of the US physician workforce is adversely impacted by work-based visa restrictions and processing backlog. Mitigating these restrictions could significantly bolster the current physician workforce and prove beneficial in our response to the COVID-19 pandemic.
RESUMEN
BACKGROUND: International Medical Graduates (IMGs) contribute to about 23% of the physician workforce in the USA. Certain US-trained IMGs face long wait times for transitioning to a permanent resident status, which limits their ability to work to fullest capacity, especially during a public health emergency. OBJECTIVES: To estimate the number of US-trained IMGs awaiting permanent residency. STUDY DESIGN: Data were obtained from National Residency Matching Program (NRMP) to quantify the number of IMGs who secured residency training in the US from 2004 to 2020. Estimates of physician demographics were based on NRMP/ECFMG 2014 match data and Federation of State Medical Boards (FSMB) physician census data. RESULTS: Between 2004 and 2020, a total of 57,160 non-US IMGs who were not US citizens successfully matched to residency training programs. Applicants from India and China were noted to be impacted by delays in adjustment to permanent resident status. Per our estimate, there are between 1,460 and 1,959 US-trained physicians from China currently awaiting permanent residency, with applicants waiting since October 2015, and between 13,250 and 14,230 US-trained physicians from India currently awaiting permanent residency, with applicants waiting since June 2009. CONCLUSIONS: The total number of US-trained immigrant physicians in active practice awaiting permanent residency to the USA is estimated to be ranging between 14,710 and 16,189.
