Protocol to study secretome interactions using extracellular proximity labeling.

Biotin ligase-based proximity ligation is a widely used, highly effective technique for the study of in vivo protein-protein interactions. However, there are few reports and little consensus on the most effective methods for studying the proximal interactomes of secreted factors. Here, we present a protocol for studying extracellular proximal interactomes using an adaptation of TurboID/BioID2-based proximity ligation.

Identifying therapeutic candidates for endometriosis through a transcriptomics-based drug repositioning approach.

Existing medical treatments for endometriosis-related pain are often ineffective, underscoring the need for new therapeutic strategies. In this study, we applied a computational drug repurposing pipeline to stratified and unstratified disease signatures based on endometrial gene expression data to identify potential therapeutics from existing drugs, based on expression reversal. Of 3,131 unique genes differentially expressed by at least one of six endometriosis signatures, only 308 (9.

Viral specific T cell therapy in kidney transplant recipients - A single-center experience.

Background: Viral infections such as adenovirus (ADV), BK virus (BKV), and cytomegalovirus (CMV) after kidney transplantation negatively impact outcomes in transplant recipients despite advancements in screening and antiviral therapy. We describe our experience of using the virus-specific T cell therapy (VSTs) in kidney transplant recipients (KTR) at our transplant center.

Methods: This is a retrospective, single center review of KTR with ADV, BKV and CMV infections between June 2021 and December 2022.

Impaired gastric accommodation in patients with postprandial distress syndrome type of functional dyspepsia assessed by 2D ultrasonography.

Background And Purpose: The pathophysiology of postprandial distress syndrome includes impaired gastric accommodation, hypersensitivity to gastric distension and delayed gastric emptying. 2D-ultrasonography is one of the methods to assess gastric accommodation by measuring proximal gastric area and we evaluated its role in calculating proximal gastric area and thus assessing gastric accommodation in Indian patients with postprandial distress syndrome.

Methods: In a hospital-based comparative analysis, proximal gastric area was measured with 2D-ultrasonography of postprandial distress syndrome (PDS) patients and compared with healthy controls.

Treatment Options for Coronavirus Disease 2019 in Patients With Reduced or Absent Kidney Function.

Coronavirus disease 2019, the disease caused by the severe acute respiratory syndrome coronavirus 2 virus, was first identified in the Hubei Province of China in late 2019. Currently, the only role for therapy is treatment of the disease, as opposed to postexposure prophylaxis, however multiple clinical trials are currently ongoing for both treatment and prophylaxis. Treating coronavirus disease 2019 relies on two components; the first is inhibition of the viral entrance and replication within the body and the second is inhibition of an exacerbated immune response which can be seen in patients with severe disease.

Use of Panel-Reactive Antibody Testing in the Planning and Management of Ocular Surface Stem Cell Transplantation.

Purpose: Panel-reactive antibody (PRA) testing has been widely adopted in solid organ transplantation for risk assessment in potential allograft recipients but has not been studied in the context of ophthalmic transplantation. The purpose of this study is to evaluate outcomes in patients undergoing ocular surface stem cell transplantation (OSST) for limbal stem cell deficiency (LSCD) relative to preoperative PRA level.

Methods: This is retrospective chart review of all eyes with documented PRA level that underwent OSST for LSCD between May 2000 and March 2019 at a single institution.

Clinical Outcomes of Allogeneic Ocular Surface Stem Cell Transplantation in Pediatric Patients.

Purpose: To describe the outcomes of allograft ocular surface stem cell transplantation (OSST) and the complication profile of systemic immunosuppression (SI) in pediatric patients with limbal stem cell deficiency.

Methods: This was a retrospective interventional case series from a single tertiary referral institution of 20 eyes from 13 patients who 1) underwent allograft OSST surgery, 2) were 18 years or less at time of OSST, and 3) received SI with 4) a minimum of 12-months follow-up. The main outcome measures were ocular surface stability, visual acuity, and SI adverse events.

Impact of obesity on dialysis and transplant and its management.

Obesity is increasing to unprecedented levels, including in the end-stage kidney disease population, where upwards of 60% of kidney transplant patients are overweight or obese. Obesity poses additional challenges to the care of the dialysis patient, including difficulties in creating vascular access and inserting Tenckhoff catheters, higher rates of catheter malfunction and peritonitis, the need for longer and/or more frequent dialysis (or peritoneal dialysis [PD] exchanges) to achieve adequate clearance, increased metabolic complications particularly with PD, and obesity is a barrier to kidney transplantation. In this article, we review special considerations in performing PD, hemodialysis and transplant in the obese patient, as well as the evidence behind medical and surgical management of obesity in dialysis patients.

Long-term Outcomes of Living-Related Conjunctival Limbal Allograft Compared With Keratolimbal Allograft in Patients With Limbal Stem Cell Deficiency.

Purpose: To compare the long-term outcomes of living-related conjunctival limbal allograft (lr-CLAL) with keratolimbal allograft (KLAL) in patients with limbal stem cell deficiency.

Methods: A retrospective, comparative, interventional cohort of patients with bilateral total limbal stem cell deficiency who underwent surgical treatment with a KLAL or lr-CLAL procedure alone (not combined with any other ocular surface stem cell transplantation procedures) with a minimum follow-up of 1 year and who received systemic immunosuppression. Ocular surface stability, best-corrected visual acuity (BCVA), and postoperative complications at the last follow-up were the main outcome measures.

Reducing Donor-specific Antibody During Acute Rejection Diminishes Long-term Renal Allograft Loss: Comparison of Early and Late Rejection.

Background: Reduction in donor-specific antibody (DSA) has been associated with improved renal allograft survival after antibody-mediated rejection (AMR). These observations have not been separately analyzed for early and late AMR and mixed acute rejection (MAR). The purpose of this study was to evaluate long-term responses to proteasome inhibitor-based therapy for 4 rejection phenotypes and to determine factors that predict allograft survival.

Perioperative implications of Coronary-cameral fistula.

Coronary-cameral fistulas (CCFs) are mostly congenital in origin and rarely acquired. Clinical symptoms are decided by the hemodynamic significance of the coronary fistula. Even in asymptomatic patients, it is essential to know about coronary CCF particularly if the patient is to undergo cardiac surgery with cardioplegic cardiac arrest.

Ipsilateral foot drop after aortobifemoral bypass.

Peripheral nerves can be injured by a direct result of the anesthetic technique of regional anesthesia or it can be contributed/compounded by poor perioperative positioning and padding, tourniquets, and the nature of surgery and diseases affecting the microvasculature of nerves. We present a case of perioperative peripheral nerve injuries which could not be explained by anesthesia technique nor surgery per se.

Long-term outcomes in patients with obesity and renal disease after sleeve gastrectomy.

Morbid obesity is a barrier to kidney transplant in patients with end-stage renal disease (ESRD). Laparoscopic sleeve gastrectomy (SG) is an increasingly considered intervention, but the safety and long-term outcomes are uncertain. We reviewed prospectively collected data on patients with ESRD and chronic kidney disease (CKD) undergoing SG from 2011 to 2018.

Methods: Retrospective interventional case series.

Results: We present 5 eyes of 3 patients with KID syndrome that developed LSCD and underwent OSST.

A curious case of raised gradient across mitral bioprosthetic valve.

High Doppler valve gradient is generally suggestive of valve thrombosis. However, it should be corroborated with the finding of restricted leaflet movement to confirm the diagnosis. In the present case, abnormally high gradient was not associated with limited leaflet movements or any valve thrombus.
