Reproductive Tract Microbial Transitions from Late Gestation to Early Postpartum Using 16S rRNA Metagenetic Profiling in First-Pregnancy Heifers.

Studies in recent years indicate that reproductive tract microbial communities are crucial for shaping mammals' health and reproductive outcomes. Following parturition, uterine bacterial contamination often occurs due to the open cervix, which may lead to postpartum uterine inflammatory diseases, especially in primiparous individuals. However, investigations into spatio-temporal microbial transitions in the reproductive tract of primigravid females remain limited.

Bovine Ephemeral Fever Viruses in Israel 2014-2023: Genetic Characterization of Local and Emerging Strains.

Bovine ephemeral fever (BEF) is an arthropod-borne viral disease, which frequently causes significant epizootics in susceptible water buffalo and cattle in Africa, Australia, Asia and the Middle East. In the current study, a two-stage protocol for BEFV viral isolation was developed. Data on the clinical signs, geographic distribution and phylogenetic analysis of BEFV strains isolated in Israel in 2015, 2018, 2021 and 2023 were summarized.

Intraoperative Extracorporeal Support during Lung Transplantation: Not Just for the High-Risk Patient.

The use of intraoperative mechanical support during lung transplantation has traditionally been a controversial topic. Trends for intraoperative mechanical support strategies swing like a pendulum. Historically, cardiopulmonary bypass (CPB) was the modality of choice during transplantation.

The Evaluation and Management of Coronary Artery Disease in the Lung Transplant Patient.

Lung transplantation can greatly improve quality of life and extend survival in those with end-stage lung disease. In order to derive the maximal benefit from such a procedure, patients must be carefully selected and be otherwise healthy enough to survive a high-risk surgery and sometimes prolonged immunosuppressive therapy following surgery. Patients therefore must be critically assessed prior to being listed for transplantation with close attention paid towards assessment of cardiovascular health and operative risk.

Worth a Double Take? An In-Depth Review of Lung Retransplantation.

Provided advancements in Lung Transplantation (LT) survival, the efficacy of Lung Retransplantation (LRT) has often been debated. Decades of retrospective analyses on thousands of LRT cases provide insight enabling predictive patient criteria for retransplantation. This review used the Preferred Reporting Items for Systematic Reviews and Meta Analyses (PRISMA) guidelines.

Single Lung Transplant for Secondary Pulmonary Hypertension: The Right Option for the Right Patient.

: The optimal treatment for Secondary Pulmonary Hypertension from End-Stage Lung Disease remains controversial. Double Lung Transplantation is widely regarded as the treatment of choice as it eliminates all diseased parenchyma and introduces a large volume of physiologically normal allograft. By comparison, the role of single lung transplantation for pulmonary hypertension (PAH) is less clear.

Adding complexity to complexity: The role of concomitant cardiac surgery in lung transplantation.

Outcomes of lung transplantation have greatly improved over recent years. While patients with concomitant cardiac pathology used to be excluded from lung transplant, today, most of these cardiac conditions can be addressed safely and effectively. Interventional techniques should be preferred.

Cardiac Sympathetic Denervation for Refractory Ventricular Arrhythmia in Continuous-Flow Left Ventricular Assist Device.

Cardiac sympathetic denervation has been shown to reduce sustained ventricular arrhythmias and implantable cardioverter-defibrillator shocks by inhibiting sympathetic outflow to the heart. We describe the first case to our knowledge of cardiac sympathetic denervation in the left ventricular assist device population. ().

Retransplantation Outcomes at a Large Lung Transplantation Program.

Background: With the increase of primary lung transplantation across major centers worldwide, over the last several years the need of lung retransplant (ReTX) is likely to increase. Therefore, characterization of ReTX patients is prudent and necessary. Our study aimed to investigate and characterize the covariates and outcomes associated with lung ReTX survival in a single large U.

Long-Term Survival in Bilateral Lung Transplantation for Scleroderma-Related Lung Disease.

Background: Lung disease is the leading cause of morbidity and death in scleroderma patients, but scleroderma is often considered a contraindication to lung transplantation because of concerns for worse outcomes. We evaluated whether 5-year survival in scleroderma patients after lung transplantation differed from other patients with restrictive lung disease.

Methods: This was a single-center, retrospective cohort study of all patients undergoing bilateral lung transplantation for scleroderma-related pulmonary disease between January 2006 and December 2014.

Characterization and identification of microbial communities in bovine necrotic vulvovaginitis.

Bovine necrotic vulvovaginitis (BNVV) is a severe and potentially fatal disease of post-partum cows that emerged in Israel after large dairy herds were merged. While post-partum cows are commonly affected by mild vulvovaginitis (BVV), in BNVV these benign mucosal abrasions develop into progressive deep necrotic lesions leading to sepsis and death if untreated. The etiology of BNVV is still unknown and a single pathogenic agent has not been found.

Case Report: Chronic Recurrent Unilateral Pulmonary Infection: Result of Congenital Unilateral Agenesis of Pulmonary Artery.

Unilateral agenesis of the pulmonary artery (UAPA) is a rare congenital anomaly. This report describes a 52-year-old female who gave a long history of chronic, recurrent, left-sided pulmonary infections related to UAPA. For many years, she was managed medically but the infection continued to recur.

Impact of pre-operative coronary artery disease on cardiovascular events following lung transplantation.

Background: This study examined the correlation between pre-operative coronary artery disease (CAD) and post-operative cardiovascular events in lung transplant recipients.

Methods: Consecutive isolated lung transplant recipients from 2007 to 2013 in our institution were identified and categorized as having significant CAD (≥ 50% coronary stenosis in at least 1 artery or history of coronary revascularization) or no-mild CAD. Patient records and death index data were analyzed for a median of 2 years for death or cardiovascular events, including coronary, cerebrovascular, and peripheral artery events.

Case report: cardiac tamponade resembling an acute myocardial infarction as the initial manifestation of metastatic pericardial adenocarcinoma.

Pericardial malignancies are uncommon, usually metastatic, linked to terminal oncology patients, and rarely diagnosed premortem. A very small number of patients will develop signs and symptoms of malignant pericardial effusion as initial clinical manifestation of neoplastic disease. Among these patients, a minority will progress to a life-threatening cardiac tamponade.

The feasibility of lung transplantation in HIV-seropositive patients.

Rationale: HIV seropositivity has long been considered a contraindication to lung transplantation, primarily because of the potential risks of added immunosuppression. In the past decade, however, experience with kidney and liver transplantation in the setting of HIV infection, with achievement of satisfactory outcomes, has grown considerably. This promising development has created a need to reconsider this contraindication to lung transplantation.

Atrial arrhythmias after lung transplant: underlying mechanisms, risk factors, and prognosis.

Background: Atrial arrhythmias (AAs) early after lung transplant are frequent and have a significant impact on morbidity and mortality. However, the pathogenesis of AAs after lung transplant remains incompletely understood. In this study we aimed to determine the prevalence of atrial fibrillation (AF) and other AAs, as well as risk factors, clinical outcomes and possible underlying mechanisms associated with AAs after lung transplant.

Combined lung and liver transplantation: analysis of a single-center experience.

Patients with end-stage lung disease complicated by cirrhosis are not expected to survive lung transplantation alone. Such patients are potential candidates for combined lung-liver transplantation (CLLT), however few reports document the indications and outcomes after CLLT. This is a review of a large single-center CLLT series.

Bloodless lung transplantation in Jehovah's Witnesses: impact on perioperative parameters and outcome compared with a matched control group.

Background: Jehovah's Witnesses (JW) refuse to receive blood products due to their religious beliefs. Bloodless transplantation programs have made the successful transplantation of solid organs like heart, liver, kidney, and pancreas in JW feasible. In this study we present the third and fourth case of a successful bloodless lung transplantation and analyze perioperative parameters and outcome with a strictly selected matched control group (CG).

Percutaneous stenting to treat pulmonary vein stenosis after single-lung transplantation.

Pulmonary vein stenosis after lung transplantation is rare. Untreated, it can cause transplant failure and death. We describe the case of a 56-year-old man in whom pulmonary vein stenosis developed after single-lung transplantation.

Extracorporeal membrane oxygenation as a bridge to emergency heart-lung transplantation in a patient with idiopathic pulmonary arterial hypertension.

Lung transplantation with or without cardiac transplantation offers the only hope of long-term, symptom-free survival for patients with advanced idiopathic pulmonary arterial hypertension. We describe a patient who underwent an emergency pulmonary embolectomy. During surgery, it was discovered that the patient had idiopathic pulmonary arterial hypertension.

Esophageal perforation in a sword swallower.

We present the case of a 59-year-old man who sustained an esophageal perforation as a result of sword swallowing. An esophagogram established the diagnosis, and surgical repair was attempted. However, 19 days later, a persistent leak and deterioration of the patient's condition necessitated a transhiatal esophagectomy with a left cervical esophagogastrostomy.

Extracorporeal membrane oxygenation for early graft dysfunction in lung transplantation: a case report.

Although extracorporeal membrane oxygenation (ECMO) has become standard treatment for neonatal respiratory failure, the results of ECMO in adults have been less encouraging. With technical improvements in membrane oxygenators and revised ECMO protocols, there has been renewed interest in ECMO for adults with severe acute respiratory failure. However, few cases of ECMO as an adjunct to adult lung transplantation have been reported.

Effect of IgM-positive crossmatches on survival in heart transplant recipients.

To determine whether an IgM-positive crossmatch adversely affects the results of heart transplantation, we conducted a retrospective study of 125 orthotopic heart transplant recipients. A direct donor-recipient crossmatch was performed retrospectively on sera from all patients by the standard National Institutes of Health (NIH) method and the antihuman globulin (AHG) procedure. The patients were then divided into 3 groups as follows.

Graft replacement of the descending thoracic aorta: results of "open" distal anastomosis.

With the advent of rapid autotransfusion, we began to repair aneurysms of the descending thoracic and thoracoabdominal aorta by using an "open" technique, in which a single cross-clamp is placed proximal to the aneurysm to exsanguinate the lower body. To determine whether open distal anastomosis effectively protects against spinal cord injury, we studied 71 consecutive patients (50 men, 21 women) who underwent this procedure beginning in April 1989. The patients ranged in age from 31 to 83 years (mean, 63.
