The Pancreatic Cancer Early Detection (PRECEDE) Study is a Global Effort to Drive Early Detection: Baseline Imaging Findings in High-Risk Individuals

Pancreatic adenocarcinoma (PC) is a highly lethal malignancy with a survival rate of only 12%. Surveillance is recommended for high-risk individuals (HRIs), but it is not widely adopted. To address this unmet clinical need and drive early diagnosis research, we established the Pancreatic Cancer Early Detection (PRECEDE) Consortium. PRECEDE is a multi-institutional international collaboration that has undertaken an observational prospective cohort study. Individuals (aged 18-90 years) are enrolled into 1 of 7 cohorts based on family history and pathogenic germline variant (PGV) status. From April 1, 2020, to November 21, 2022, a total of 3,402 participants were enrolled in 1 of 7 study cohorts, with 1,759 (51.7%) meeting criteria for the highest-risk cohort (Cohort 1). Cohort 1 HRIs underwent germline testing and pancreas imaging by MRI/MR-cholangiopancreatography or endoscopic ultrasound. A total of 1,400 participants in Cohort 1 (79.6%) had completed baseline imaging and were subclassified into 3 groups based on familial PC (FPC; n=670), a PGV and FPC (PGV+/FPC+; n=115), and a PGV with a pedigree that does not meet FPC criteria (PGV+/FPC-; n=615). One HRI was diagnosed with stage IIB PC on study entry, and 35.1% of HRIs harbored pancreatic cysts. Increasing age (odds ratio, 1.05; P<.001) and FPC group assignment (odds ratio, 1.57; P<.001; relative to PGV+/FPC-) were independent predictors of harboring a pancreatic cyst. PRECEDE provides infrastructure support to increase access to clinical surveillance for HRIs worldwide, while aiming to drive early PC detection advancements through longitudinal standardized clinical data, imaging, and biospecimen captures. Increased cyst prevalence in HRIs with FPC suggests that FPC may infer distinct biological processes. To enable the development of PC surveillance approaches better tailored to risk category, we recommend adoption of subclassification of HRIs into FPC, PGV+/FPC+, and PGV+/FPC- risk groups by surveillance protocols

Surgical modifications to the conventional kidney transplant technique - the miami transplant institute approach: a retrospective cohort study

At our center, surgical modifications to the conventional kidney transplant technique were developed with two goals in mind: to minimize the risk of developing post-transplant urologic/vascular/other surgical complications, and to simultaneously eliminate the need for initial ureteral stent placement and surgical drainage. Here, we describe these modifications along with(what we believe are) their advantages over the conventional technique: creating an abdominal flap for easier abdominal closure(reflecting the parietal peritoneum from the abdominal wall), mobilizing the bladder before transplant(creating more space for bladder dissection, allowing it to move upward during abdominal wall closure), minimizing the dissection of iliac vessels to only anterior lymphatic tissue(attempting to minimize the incidence of fluid collections), using plastic arterial vascular bulldog clamps(causing less trauma to the iliac artery), performing vascular anastomosis of the renal artery first(making it easier for the surgeon to perform this anastomoses), creating longer ureteral spatulation, and inclusion of bladder mucosa along with some detrusor muscle layer in performing the ureteral anastomosis(attempting to minimize the incidence of urologic complications). Of note, no initial ureteral stent placement or surgical drainage was used. We report our experience during the first 12mo post-transplant of a single transplant surgeon who used each of these modifications among 707 consecutive recipients of kidney-alone transplants at our center since 2014. During the first 12mo post-transplant, 2.3%(16/707) of patients developed a urologic complication; only 1.0%(7/707) required surgical repair of their original ureteroneocystostomy. Additionally, 2.7%(19/707) developed a vascular complication; 8.8%(62/707) developed some other type of surgical complication(wound complication, lymphocele development, or development of a peri-renal hematoma or peri-renal collection). These overall results were clearly advantageous when compared with other studies. We believe that this modified kidney transplant technique clearly helped in reducing post-transplant risks of developing urologic/vascular/other surgical complications. Importantly, these results were achieved without initial ureteral stent placement or surgical drainage

A cross exploratory analysis between nursing working conditions and the occurrence of errors in the northeast region of Brazil

Analyze and verify the association between working conditions and the occurrence of errors in nursing work. Many of the known errors in nursing are based on the structural failure of the complex health service system. Our study addresses the question “Is there an association between errors made by nursing workers and working conditions?” The study was carried out through a cross-sectional exploratory analysis of 19 ethical-disciplinary processes focused on errors made by nursing workers. The articles were processed, judged, and archived at the Regional Nursing Councils of the Northeast Region of Brazil from 2000 to 2018. The chi-square test or Fisher's exact test was used to verify the relationship between the variables through multivariate analysis. The analyzes show that working conditions can interfere at occurrence in error. This increases the chance of an “inconsequential” error occurring for the patient in poor/very poor working conditions. The most serious errors, “with consequences irreversible” for the patient, only occur from more severe working conditions. Adversely, it was found that there is no statistically significant difference in the frequency of errors in hospitals (33.33 %) compared to “other places” (28.58 %) when these occurred in poor working conditions. When conducting the incident in poor working conditions, there was a minimum of 52 % protection OR = 0.48 % [0.16; 11.80]; (1–0.48)) against these errors in general in the nursing area. The strong association was exposed in working conditions classified as bad/very bad/very bad, resulting in the most serious errors and with irreversible consequences for patients. However, a level of protection for different types of workers was noticed in the field, which shows that there is hope that if the work environment changes with more organization, management, and standards of care, we can prevent future errors. •The study reveals the need for greater managerial supervision of services and prioritizing the provision of quality care.•There was no difference in the frequency of errors in hospitals compared to other places when in poor working conditions.•There is an association between working conditions and the period in which errors occur when in poor conditions

Early management of adult traumatic spinal cord injury in patients with polytrauma: a consensus and clinical recommendations jointly developed by the World Society of Emergency Surgery (WSES) & the European Association of Neurosurgical Societies (EANS)

The early management of polytrauma patients with traumatic spinal cord injury (tSCI) is a major challenge. Sparse data is available to provide optimal care in this scenario and worldwide variability in clinical practice has been documented in recent studies. A multidisciplinary consensus panel of physicians selected for their established clinical and scientific expertise in the acute management of tSCI polytrauma patients with different specializations was established. The World Society of Emergency Surgery (WSES) and the European Association of Neurosurgical Societies (EANS) endorsed the consensus, and a modified Delphi approach was adopted. A total of 17 statements were proposed and discussed. A consensus was reached generating 17 recommendations (16 strong and 1 weak). This consensus provides practical recommendations to support a clinician's decision making in the management of tSCI polytrauma patients

Measuring corneal pain in the clinic

Abstract only DED is a heterogenous disease with a variety of symptoms and signs. One reality of the disease is that its symptoms (e.g., ocular surface pain described as “dryness”, “irritation”, “aching”, and/or “tenderness”) often do not align with its signs (e.g., decreased tear production, tear instability). New data suggest that corneal nerve abnormalities underlie the noted discordance between symptoms and signs. DED symptoms out of proportion to signs, as is often seen co‐morbid with pain conditions such as migraine and fibromyalgia, may indicate that neuropathic mechanisms contribute to symptoms. DED signs out of proportion to symptoms, as is often seen co‐morbid with diabetes mellitus, may indicate that neurotrophic mechanisms are involved. Given this reality, testing for corneal nerve function is an important, but often overlooked, component of the ocular surface examination. This presentation will review strategies to test corneal nerve function in the clinical arena, and discuss treatments that can be used when corneal nerve abnormalities are detected

A phase 2 randomized, placebo-controlled crossover trial to evaluate safety and efficacy of platelet-rich plasma injections for Peyronie's disease: clinical trial update

Peyronie's Disease (PD) is characterized by fibrotic plaques in the penile tunica albuginea, causing curvature and painful erections. Current treatments have limited established efficacy. Platelet-Rich Plasma (PRP), known for modulating inflammation, offers a potential alternative. This randomized, placebo-controlled, crossover study at the University of Miami assesses PRP's safety and efficacy for PD. Forty-one PD patients were randomized into PRP-placebo (Group A) and placebo-PRP (Group B) sequences, receiving two injections of each treatment over three months, with a crossover to receive two injections of alternate treatment over the next three months. Assessments include pain scale, goniometry, questionnaires, and curvature evaluations. Preliminary analysis of 28 patients shows that PRP is safe. There were no adverse events, including penile complications, during follow-up. Pain scores during treatments showed no significant difference between PRP and placebo (p = 0.52). Over six months, the PRP-Placebo group's median PDQ score decreased from 1.9 (IQR: 1.7-2.9) to 1.4 (IQR: 0.7-2.1). This change was not statistically significant (p = 0.098). In contrast, the Placebo-PRP group showed a significant reduction from 1.8 (IQR: 1.4-2.6) to 1.2 (IQR: 1.0-2.0) (p = 0.020). No significant changes in IIEF scores were observed. Both groups initially had a median penile curvature of 40 degrees. At 3 months, the PRP-Placebo group's curvature decreased to 38 degrees (IQR: 35-47.5), while the Placebo-PRP group decreased to 35 degrees (IQR: 30-60). At 6 months, the PRP-Placebo group showed a significant reduction to 25 degrees (IQR: 20-40, p = 0.047), while the Placebo-PRP group's reduction to 32.5 degrees (IQR: 20-50) was not significant (p = 0.490). These early results indicate a delayed PRP effect, prompting further investigation into its long-term impacts. Although limited by sample size, this study suggests PRP injections as a safe treatment for PD, with ongoing research aiming to clarify its therapeutic value

SNUPN deficiency causes a recessive muscular dystrophy due to RNA mis-splicing and ECM dysregulation

SNURPORTIN-1, encoded by SNUPN, plays a central role in the nuclear import of spliceosomal small nuclear ribonucleoproteins. However, its physiological function remains unexplored. In this study, we investigate 18 children from 15 unrelated families who present with atypical muscular dystrophy and neurological defects. Nine hypomorphic SNUPN biallelic variants, predominantly clustered in the last coding exon, are ascertained to segregate with the disease. We demonstrate that mutant SPN1 failed to oligomerize leading to cytoplasmic aggregation in patients' primary fibroblasts and CRISPR/Cas9-mediated mutant cell lines. Additionally, mutant nuclei exhibit defective spliceosomal maturation and breakdown of Cajal bodies. Transcriptome analyses reveal splicing and mRNA expression dysregulation, particularly in sarcolemmal components, causing disruption of cytoskeletal organization in mutant cells and patient muscle tissues. Our findings establish SNUPN deficiency as the genetic etiology of a previously unrecognized subtype of muscular dystrophy and provide robust evidence of the role of SPN1 for muscle homeostasis
